How do software companies get things so wrong?  I aim this at both Google and Apple here, as both are equally as guilty of this.  Maybe Microsoft can learn from this?

So you see something on an “app store” that might be useful on the device you’re using.  Ohh, a free download, great!  Let’s download.  You click the link, and immediately get asked for a login and password.  There’s no option to proceed without.  They insist you create an account with them even if it’s the one and only thing you’re interested from them.

In the past my gripe has been with the Google Play store.  Even the “free” apps, require you to log in.  Ohh, and to add insult to injury, the Google Play store doesn’t just expect any Google account, it has to be one of their Gmail accounts.  Back in the late 90s I had an email address with most providers as the average quota was about 5MB.  I’ve had a mailbox of my own with a multi-gigabyte (actually limited only by disk capacity) “quota” since 2002, I have no use for Gmail, and only keep my old Yahoo! address (created in 1999) for historic reasons.

I have an Android phone (release 4.1: thanks to ZTE’s backward thinking and short attention span), and thankfully there’s the F-Droid store which has sufficient applications for my use.  So I can work around the Google Play store most of the time and so far, haven’t needed anything from there.

Today, my gripe is at Apple, and the “app” in question is MacOS X, which cannot be obtained anywhere else.

With all the high-profile attacks on websites that store user accounts, one has to ask, why?  It’s one extra username and password, which given the frequency I’m likely to use it, will have to be written down and stored somewhere secure as it won’t get sufficient use to commit it to memory.  Before people point out password managers, I’d like to point out one thing: it’s still writing it down!

There’s absolutely no need for an “app store” to know your email address, usernames, passwords, or any details.  If you are actually purchasing an application, they only need enough information to process a payment.

Usually this is by a debit/credit card, so they need to know the details on the card.  An alternative might be direct deposit through a bank, at which point they need to supply you with details on how to make the payment — details that include the information they need to match your payment in their ledger to your store purchase.  At no point do they need anything else.

For convenience an email address might be supplied so they can confirm your order or contact you if there’s a problem, however for debit/credit cards, this happens so quickly that it can be achieved via the web browser.

Despite this, they insist on you providing just about everything.

I’m no stranger to the “app store” concept.  Linux and BSD distributions have had this sort of concept for years.  BSD has had ports for as long as I can remember.  Debian had apt since 1998, Gentoo has had portage since its inception in 2003 and RPM-based distributions have had yum for some time too.

None of these actually need to know who you are in order to download a package.  Admittedly none of these are geared toward commercial sales of software, and so lack the ability to prompt for credentials or payment information.

Since both Google Play and the Apple App store have solved the former problem, I see no reason why they couldn’t solve the latter.  I don’t want to post anything to the site, I don’t want to leave feedback as I can hardly comment on something I haven’t received yet, and I don’t know when I’ll next visit the site.

If I was going to be back repeatedly, sure, I’ll make an account.  It’ll make everyone’s lives easier. (Including the blackhats!)  But I’m not.  I have a late-2008 model MacBook, probably the oldest machine that Apple support for their latest OS.  The machine dual-boots MacOS X 10.6 and Gentoo Linux, and spends 99% of its time in the latter OS.

Given the age of the machine and the frequency at which I use its native OS, it is not worth me spending a lot of time or expense updating it.  A 2GHz Core 2 Duo with 8GB RAM and a 750GB HDD is good enough for many tasks under Linux, but is the bare minimum to run OS X 10.10.  The only reason this machine doesn’t grace my desk at work anymore is the fact the lack of ports (USB in particular) proved to be a right pain.

Why update?  Well, applications these days seem to expect at least MacOS X 10.7 now.  I either have to build everything myself or update the OS, so I’m investigating the possibility of updating the OS to see if it’s feasible.  Apparently it’s a free download, so why not?

Well, why not indeed!  Instead of having a simple http, https or ftp link to the file in question (maybe a .dmg image) for software they’re not actually selling to me in the traditional sense, they instead insist on making me jump through hoops like requiring their “app store” client — so I can’t just grab the link, tell the web server here to download the file then grab it from there when I’m ready.

Since I can’t do the download any other way than via their “app store” client, I have to remain booted in MacOS X in order to download it regardless of what I might otherwise wish to do the machine and what OS that requires.

However, before I can even think about starting the download, I’ve got to register an account, supplying a username and password for something that will probably be used exactly once.  Details that they have to pay people big money to store securely.

Instead of spending some money paying someone to add an extra one-off button and form to their “app store” clients, they instead spend significantly more on infrastructure designed to meet the privacy requirements of various laws to store user information that simply is not necessary for the transaction to proceed.

In light of the sophistication of the modern cracker and the cut-throat nature of the mobile market, is this such a wise use of company funds?

Dec 102014
 

This afternoon we started getting some unusual calls.  Now I hate those survey calls, or telemarketing calls wanting to sell you some kind of service.  I especially hate them when they’re delivered by a recorded voice, and there’s a special place in HELL for those which claim to have found “problems with your computer”.

My troubles started earlier this afternoon.  Having gotten home from work around 3PM, I make a call to my father to find out what was happening tonight, got no answer, and so I just hung up rather than leaving a message (it wasn’t important).  He rang back and we had a quick discussion.

Some time later, the phone rings.  Now, normally when the phone rings, it’s two bursts, then silence, then two more bursts, then silence … etc.  This had a different initial rhythm: one long burst, then silence, then the usual pattern.  I answered, only to be greeted by silence, then an automated voice.  I hung up straight away.

Normally that’d be the end of it.  Then history repeats itself, after 5 minutes the phone ring again.  Same pattern.  I answer, and get the same silence, followed by a voice recording.  I hang up, again.

Cue this happening about 3 or 4 times.  So I look up the Telstra website and found their help-desk number.  I also paid a visit to the Do Not Call register for good measure.  (We had done it before, but maybe it had expired?).  A computer system answers (typical), and after answering a few prompts, I’m told there will be a 7 minute wait.

Well, 7 minutes turned out to be 25 minutes, but who’s counting?  I guess Steven Travalgia is right about the “variable viscosity of time” theory, it certainly applies to help-desk queues!  That said, at least I wasn’t getting nuisance calls.

I explain the situation to the operator.  Naturally, not being the account holder, they cannot do much, but at least there’s a record of me calling, they mention they can enable tracing to find out what’s going on.  They give me a direct line for their unwanted calls department, and I reply stating I’ll take some logs of what happens and call that number when I have some evidence.

17:04 4 rings, dial tone on pick up
17:05 3 rings, stopped ringing before answer
17:12 2 rings, dial tone on pick up
17:52 Answered and recorded.

I recorded this (apologies for the clipping, my mic gain was up a bit high):

Now it’s worth noting that nothing currently plugged into the phone line can receive SMS messages.  Our phone line terminates in our garage at a ADSL2+ central splitter (installed by yours truly).

One CAT5e cable is divided into one ADSL circuit and 3 voice circuits and runs into the office, providing service for the ADSL router/modem, a multi-function fax/printer/scanner, a General Electric speaker phone (with corroding AA batteries, so maybe that phone will go in the bin now), a (Telstra-branded) cordless phone base station and a 56k modem.

The other feed coming out of the splitter box is original house wiring, and terminates upstairs with an old Telecom Australia Touchfone 200 that probably remembers the days of our house having a 6-digit number.  (Our line is that old.)

Nothing that will receive messages, or confuse the hell out of the delivery centre.  It seems if there’s nothing on the line, they just keep ringing persistently, making the service a very cheap and efficient way to harass someone at all hours of the night!

Sadly, a quick search does not tell one how to disable this service.  I have no reason to receive SMS messages on a land-line, I have a mobile for that.  If I find out how, I’ll be updating this.

Geez, you’re getting as bad as another mob I could mention, although in your favour, you at least make it clear from the WHOIS data that it’s a guest on your network that’s stirring up trouble.

Well, it has been a long time since I last logged in on the Atomic MPC forums.  Years in fact.  I was at one time, quite active, particularly in what was the “Unix, Linux and Open Source” forum, back in the days when their forum software was an entirely in-house production.

Lately, my work has been very IT intensive, and while some days things go great, other days it’s a struggle.  And when it’s a struggle, the last thing one wants to look at is a computer.

Now when I was active on the Atomic forums, the threads used to move rather fast.  In their move to VBulletin we gained the ability to subscribe to threads and get notified of replies.  A feature I made quite extensive use of.  It was a useful way to keep track of what was happening.

One day I decided I had enough, rather than draw attention to myself with a leaving thread, I just quietly left.  I continued to watch the threads from a distance, and over time, the replies got less and less frequent as the threads slipped off the front page.  I hadn’t seen an email from Atomic for well over two years, until the other day.  Bam!  I had over 200 emails in one hit!

I thought this was just a one-off glitch, so I ignored it.  Then Bam!  A few days later it happened again.

I suppose it’s happened 4 or 5 times now.  What does it look like?

Atomic MPC spam

Atomic MPC spam

Yes indeedy, that’s my email inbox, and there is more crap from old threads that are old enough to be stored on wooden platter hard drives than legitimate email in my Inbox.

I’ve just recovered my account and hopefully unsubscribed myself from these notifications.  However, to the Atomic MPC mods, be warned, if this continues I will be taking this up with the ACMA as the constant barrage my server is copping is getting beyond a joke.

Oi, Microsoft, yes You!

See this?  Now Bugger Off!  Your lack of self-control was pushing my poor server’s CPU through the roof, so I blocked you.  Now I see you’re back and after the 403 you still aren’t taking the hint!

Search just about anywhere else on this site, no problems.  But the git repositories, those are both CPU and I/O intensive.  Had you noticed how long it was taking, and backed off, I might’ve put up with you, but 5-minute CPU load averages in excess of 80 on a dual-core Intel Atom are no fun.

Go bing up someone else’s host!

Just a quick note. I’ve been getting a lot of spambots registering on this site of late. Probably at least 3 an hour.

Thus I have implemented a new policy. Inactive accounts older than a week 3 days old who have posted no comments will be deleted. I will quarantine the account, and can re-instate it should an account be mistakenly deleted.

The comment doesn’t have to be approved, it can be in moderation. If the comment is spam, the account and comment will be deleted upon discovery. So spambots, go ahead, it’ll let me hunt you sooner. Or don’t even bother creating the account, no one will see it so it’s a waste of time anyway.

Entered into an eBay contact form.

Hi, Just a short note.

I am closing my account: the form that asks why didn’t really capture the true reason why I’m closing.

It’s not quite “identity theft”, but it is security-related.

I haven’t been using my eBay account, so I thought I’d set the password to something nice and *strong*. On the password change form, I noticed a 20-character maximum limit.

This was red flag no. 1.

Then I pasted a randomised password from a generator. The site complained I had forbidden characters.

This was red flag no. 2.

By placing limits on the size of password and its content, it is clear to me that eBay is *not* serious about making its systems truly secure, and that breaches like the one experienced recently will be a recurring event.

By hiding behind “proprietary encryption” it isn’t even serious about reassuring the public: good crypto doesn’t need secret algorithms to work well.

As there’s now very little I buy off eBay, I feel the time has come to say goodbye. If you ever do get your act together, I might consider returning, but until then, farewell.

Hi all,

Not often I have a whinge about something, but this problem has been bugging me of late more than somewhat.  I’m in the process of setting up an OpenStack cluster at work.  Now, as the underlying OS we’ve chosen Ubuntu Linux which is fine.  Ubuntu is a quite stable, reliable and well supported platform.

One of my pet peeves though, is when some package manager decides to get lazy.  Now, those of us who have been around the Linux scene have probably discovered RPM dependency hell… and the smug Debian users who tell us that Debian doesn’t do this.

Ho ho, errm… no, when APT wants to go into dummy mode, it does so with style:

Now this is probably one of my most hated things about computing, is when a software package accuses YOU of doing something that you haven’t. Excuse me… I have held broken packages? I simply performed a fresh install then told you to do an install!

So let’s have a closer look.

Okay, closer, so we need to install those too. But hang on, isn’t that apt‘s responsibility to know this stuff? (which it clearly does).

Also note we don’t get told why it isn’t going to be installed. It refuses to install the packages, “just because”. No reason given.

We try adding in the deps to our list.

Aha, so there’s a newer version in the Ubuntu repository that’s overriding ours. Brilliant. Ohh, and there’s a mysql-client binary too, but it won’t tell me what version it’s trying for.

Looking in the repository myself I spot a package named mysql-common_5.5.33a+maria-1~raring_all.deb. That is likely our culprit, so I try version 5.5.33a+maria-1~raring.

Gentoo: Increasing blood pressure since 1999.

it doesn’t just apply to Gentoo!

Mar 082013
 

Just recently, I managed to kill yet another hand-held. Not deliberately, just a combination of conditions and not adapting my behaviour to suit.

I have a Yaesu VX8-DR, which I mainly use on the bicycle for APRS. It isn’t bad, the GPS could be faster, and the Bluetooth is more of a gimmick (in that it only works with some Bluetooth headsets and is intermittent at best), but my biggest nit with it, is that you can’t charge the thing while it’s turned on.

This leads me to the bad habit of just leaving a DC power lead semi-permanently plugged into the side, with the other end plugged into the 12V supply on the bicycle. You guessed it… one bad day of rain, some water got in via the DC jack and basically destroyed it.  I’m pretty sure warranty doesn’t cover that kind of abuse.

I’m not in a hurry to buy another one.  In fact, I probably won’t.  I’m too clumsy to look after an expensive one, so better just to keep the two Chinese cheapies going (Wouxun KG-UVD1P’s).  This lead me to thinking about what I specifically like in a hand-held, and what features I’d look for.

Looking around, it seems the vast majority of sets out there are evolutionary.  An extra handful of memory channels, higher power, bigger battery, ohh look Bluetooth, and this one has {insert some semi-proprietary-digital-mode here}.  Yawn!

Most of them have tiny screens which can’t show a decent amount of information at a glance.  Digital voice is a long way being usable, with about 3 or 4 proprietary or semi-proprietary competing standards.  What about D-Star you say?  Well, what about it.  Nice mode, pity about the codec.  How about P25?  Same deal.

If a digital mode is going to succeed in Amateur radio, it’ll be necessary for a home base to be able to implement it with nothing more than a desktop or laptop computer loaded with appropriate Free Software and a sound card interface.  Not a silly proprietary “DV-Dongle” or some closed-source blob that speaks gibberish no other software can understand.

As for portable use; it should be possible for a hand-microphone that implements the mode on a DSP be plugged into an existing hand-held (like the Wouxun or Yaesu sets I mentioned earlier) to make it interoperable — open standards will help keep costs down here.

Until such a mode comes along (and they’re working on it — already making excellent progress on HF, keep it up guys!) there’s no point in pouring money into a digital mode that will be a white elephant in a few years.

By far the most popular mode on VHF and UHF is plain old FM.  The mode Armstrong made.  It’s everywhere, from your cheap $100 Chinese firecracker set to the most expensive SDR, they all offer it.  Repeaters abound, and it’s available to pretty much all amateur license classes.  And it works good enough for most.

The big problem with FM, is interfacing with repeaters.  In particular, the big use case with hand-helds and repeaters, is being able to recall the settings for a repeater where ever you happen to be.  Now you can carry around a booklet with the settings written in, and punch them into your radio each time.

This works better for some than others.  On the KG-UVD1P with its horrid UI, it is a tiresome affair.  The Yaesu VX-8DR and Kenwood TH-F7E aren’t bad, once you get used to them.  It’s still fiddly and time consuming, definitely not an option while mobile.  This is where memory channels come in.

Now I realise that sets which stored more channels than you could count on one digit-challenged hand were considered a revolution about 10 years ago.  Back then the idea that you could basically control a digital counter, which would supply an address to an EEPROM that would spit out the settings to drive a PLL synthesizer and other control circuitry was truly remarkable.

Today, the EEPROM and counter have been replaced by a MCU that reads the keypad matrix and outputs to a LCD panel, but we’re still basically incrementing a counter that’s acting as an address offset into non-volatile memory.  The only change has been the number of channels.  The Kenwood set I had gave you 400.  The VX-8, gives you 1000 — which can be optionally grouped into 24 banks (by far the best system I’ve seen to date).  The Wouxun gives you a poultry 128.

The hardest thing about this is finding a given repeater in a list.  128 is more than enough if you don’t travel, or if you pre-programme the set with the appropriate channels in some logical ordering before you leave.  In there hints another factor; “logical ordering”, since there’s no way to sort the memory channels by anything other than channel number.

In this day and age, 1000 channels, linearly indexed, is a joke.  I can buy a 2GB MicroSD card from the supermarket for $10.   How much repeater data could you store on one of those?  FAT file system drivers are readily implementable in modern MCUs and a simple CSV file is not that big a deal for a MCU to parse.

It wouldn’t be difficult to build up a few indexes of byte locations to store in NVRAM, and have the CSV store frequency, call sign, a Maidenhead locator and other settings of all the repeaters in the country, then allow the user to choose one searching by frequency, by call-sign, or if the user gives their current grid square (or it derives it from a GPS), by proximity.  That would be a revolution.  The same card could also store a list of Echolink and IRLP nodes, and make a note of such nodes via RF so it can automatically suggest the nearest IRLP node, take you there, then dial whatever node for you after you announce yourself on the frequency.

I’ve seen more elaborate software written for 8-bit micros like the Apple II, the Commodore 64 and the Sinclair ZX Spectrum back in the day, so clearly not beyond today’s equally powerful AVR, PIC, MSP430 and ARM chips.  A STM32F103RE packs 64KB RAM, 512KB flash and a SDIO interface in a nice small TQFP64 package and costs less than $8.  Even for a Wouxun, that’ll maybe add no more than 20% still keeping it rather competitive with the opposition.

As for user interface?  We don’t need Android on there, although that could be nice.  A decent size resistive touch-screen with a reflective dot-matrix LCD would more than suffice.  This technology, thanks to mobile phones, is cheap enough to implement in this application.  The MCUs needed to drive them have also come down in cost greatly.

Even without the touch-screen — a LCD bigger than a matchbox would allow for text that is easily readable, menus that aren’t constrained in their presentation, and a generally nicer user experience.

SDR hand-helds will likely be the next big revolution, if they are affordable, but I feel that’ll be a way off, and for rag chew on a local repeater, I doubt SDR will be that much superior.  It certainly will push the price up though.

I suppose a start will be to try and come up with a suitable front-end device that can be bolted onto existing transceiver hardware, maybe something that drives the computer control port of a mobile rig such as the FT-857 or IC-706.

From there, it just takes one brave manufacturer to package such a device up with a suitable transceiver in a hand-held form factor to put something to market.  If they did so in a way that could keep this UI module open-source, even better.  Bonus points if there’s a bit of an interface that can take a DSP for digital modes.

Want D-Star, P25, FreeDV, Wongi?  You got it, just slot in the right module, load on the firmware into the UI module, and away you go.  Want to do something special?  Break out the text editor and compiler and start hacking.  The RF side of things can still be as it was before, so shouldn’t pose any more of a problem for regulators than a transceiver with a digital modes jack and computer control interface.

I’m not sure if anyone has worked on such a front-end.  Another option would be a cradle that takes a modern smart-phone or tablet, interfaces via USB to the set, and uses the smart-phone as the UI, also extending the phone’s battery at the same time by supplying the 5V it needs to charge.  Bonus points if it can feed the audio signal to/from the phone for digital modes and/or interfacing with BlueTooth.  A pocket APRS I-Gate and Echolink node, perhaps?  Whatever takes your fancy.

I guess the real answer here will be to come up with something and see if there’s any interest — the “throw it against the wall and see what sticks” approach.

Warning, this is a long post written over some hours. It is a brain dump of my thoughts regarding user interfaces and IT in general.

Technology is a funny beast. Largely because people so often get confused about what “technology” really is. Wind back the clock a few hundred millenia, then the concept of stone tools was all the rage. Then came metallurgy, mechanisation, industrialisation, with successive years comes a new wave of “technology”.

Today though, apparently it’s only these electronic gadgets that need apply. Well, perhaps a bit unfair, but the way some behave, you could be forgiven for thinking this.

What is amusing though, is when some innovation gets dreamt up, becomes widespread (or perhaps not) but then gets forgotten about, and re-discovered. No more have I noticed this, but in the field of user interfaces.

My introduction to computing

Now I’ll admit I’m hardly an old hand in the computing world. Not by a long shot. My days of computing go back to no later than about the late 80’s. My father, working for Telecom Australia (as they were then known) brought home a laptop computer.

A “luggable” by today’s standards, it had no battery and required 240V AC, a smallish monochrome plasma display with CGA graphics. The machine sported a Intel 80286 with a 80287 maths co-processor, maybe 2MB RAM tops, maybe a 10MB HDD and a 3.5″ floppy drive. The machine was about 4 inches high when folded up.

It of course, ran the DOS operating system. Not sure what version, maybe MS-DOS 5. My computing life began with simple games that you launched by booting the machine up, sticking in a floppy disk (a device you now only ever see in pictorial form next to the word “Save”) into the drive, firing up X-Tree Gold, and hunting down the actual .exe file to launch stuff.

Later on I think we did end up setting up QuikMenu but for a while, that’s how it was. I seem to recall at one point my father bringing home something of a true laptop, something that had a monochrome LCD screen and an internal battery. A 386 of some sort, but too little RAM to run those shiny panes of glass from Redmond.

Windows

I didn’t get to see this magical “Windows” later until about 1992 or ’93 or so when my father brought home a brand-new desktop. A Intel 486DX running at 33MHz, 8MB RAM, something like a 150MB HDD, and a new luxury, a colour VGA monitor. It also had Windows 3.1.

So, as many may have gathered, I’ve barely known computers without a command line. Through my primary school years I moved from just knowing the basics of DOS, to knowing how to maintain the old CONFIG.SYS and AUTOEXEC.BAT boot scripts, dealing with WIN.INI, fiddling around with the PIF editor to get contankerous DOS applications working.

Eventually I graduated to QBasic and learning to write software. Initially with only the commands PRINT and PLAY, baby steps that just spewed rubbish on the screen and made lots of noise with the PC speaker, but it was a start. I eventually learned how to make it do useful things, and even dabbled with other variants like CA Realizer BASIC.

My IT understanding entirely revolved around DOS however and the IBM PC clone. I did from time to time get to look at Apple’s offerings, at school there was the odd Apple computer, I think one Macintosh, and a few Apple IIs. With the exception of old-world MacOS, I had not experienced a desktop computer OS lacking a command line.

About this sort of time frame, a second computer appeared. This new one was a AMD Am486DX4 100MHz with I think 16MB or 32MB RAM, can’t recall exactly (it was 64MB and a Am5x86 133MHz by the time the box officially retired). It was running a similar, but different OS, Windows NT Workstation 3.1.

At this point we had a decent little network set up with the two machines connected via RG58 BNC-terminated coax. My box moved to Windows for Workgroups 3.11, and we soon had network file sharing and basic messaging (Chat and WinPopup).

Windows 95

Mid 1996, and I graduated to a new computer. This one was a Pentium 133MHz, 16MB RAM, 1GB HDD, and it ran the latest consumer OS of the day, Windows 95. Well, throw out everything I knew about the Program Manager. It took me a good month or more to figure out how to make icons on the desktop to launch DOS applications without resorting to the Start ? Run ? Browse dance.

After much rummaging through the Help, looking at various tutorials, I stumbled across it quite by accident — the right-click on the desktop, and noticing a menu item called “New”, with a curious item called “Shortcut”.

I later found out some time later that yes, Windows 95 did in fact have a Program Manager, although the way Windows 95 renders minimised MDI windows meant it didn’t have the old feel of the earlier user interface. I also later found out how to actually get at that start menu, and re-arrange it to my liking.

My father’s box had seen a few changes too. His box moved from NT 3.1, to 3.5, to 3.51 and eventually 4.0, before the box got set aside and replaced by a dual Pentium PRO 200MHz with 64MB RAM.

Linux

It wasn’t until my father was going to university for a post-grad IT degree, that I got introduced to Linux.In particular, Red Hat Linux 4.0. Now if people think Ubuntu is hard to use, my goodness, you’re in for a shock.

This got tossed onto the old 486DX4/100MHz box, where I first came to experiment.

Want a GUI? Well, after configuring XFree86, type ‘startx’ at the prompt. I toiled with a few distributions, we had these compilation sets which came with Red Hat, Slackware and Debian (potato I think). First thing I noticed was the desktop, it sorta looked like Windows 95.

The window borders were different, but I instantly recognised the “Start” button. It was FVWM2 with the FVWMTaskBar module. My immediate reaction was “Hey, they copied that!”, but then it was pointed out to me, that this desktop environment was somewhat older than the early “Chicago” releases by at least a year.

The machines at the uni were slightly different again, these ones did have more Win95-ish borders on them. FVWM95.

What attracted me to this OS initially was the games. Not the modern first person shooters, but games like Xbilliard, Xpool, hextris, games that you just didn’t see on DOS. Even then, I discovered there were sometimes ports of the old favourites like DOOM.

The OS dance

The years that followed for me was an oscillation between Windows 3.1/PC DOS 7, Windows 95, Slackware Linux, Red Hat Linux, a little later on Mandrake Linux, Caldera OpenLinux, SuSE Linux, SCO OpenServer 5, and even OS/2.

Our choise was mainly versions of SuSE or Red Hat, as the computer retailer near us sold boxes of them. At the time our Internet connection was via a belovid 28.8kbps dial-up modem link with a charge of about $2/hr. So downloading distributions was simply out of the question.

During this time I became a lot more proficient with Linux, in particular when I used Slackware. I experimented with many different window managers including: twm, ctwm, fvwm, fvwm2, fvwm95, mwm, olvwm, pmwm (SCO’s WM), KDE 1.0 (as distributed with SuSE 5.3), Gnome + Enlightenment (as distributed with Red Hat 6.0), qvwm, WindowMaker, AfterStep.

I got familiar with the long-winded xconfigurator tool, and even getting good at having an educated guess at modelines when I couldn’t find the specs in the monitor documentation. In the early days it was also not just necessary to know what video card you had, but also what precise RAMDAC chip it had!

Over time I settled on KDE as the desktop of choice under Linux. KDE 1.0 had a lot of flexibility and ease of use that many of its contemporaries lacked. Gnome+Enlightenment looked alright at first, but then the inability to change how the desktop looked without making your own themes bothered me, the point and click of KDE’s control panel just suited me as it was what I was used to in Windows 3.1 and 95. Not having to fuss around with the .fvwm2rc (or equivalent) was a nice change too. Even adding menu items to the K menu was easy.

One thing I had grown used to on Linux was how applications install themselves in the menu in a logical manner. Games got stashed under Games, utilities under Utilities, internet stuff under Internet, office productivity tools under Office. Every Linux install I had, the menu was neatly organised. Even the out-of-the-box FVWM configuration had some logical structure to it.

As a result, whenever I did use Windows on my desktop, a good amount of time was spent re-arranging the Start menu to make the menu more logical. Many a time I’d open the Start menu on someone else’s computer, and it’d just spew its guts out right across the screen, because every application thinks itself deserving of a top-level place below “Programs”.

This was a hang-over of the days of Windows 3.1. The MDI-style interface that was Program Manager couldn’t manage anything other than program groups as the top-level, and program items below that. Add to this a misguided belief that their product was more important than anyone elses, application vendors got used to this and just repeated the status quo when Windows 95/NT4 turned up.

This was made worse if someone installed Internet Explorer 4.0. It invaded like a cancer. Okay now your screenful of Start menu didn’t spew out across the screen, it just crammed itself into a single column with tiny little arrows on the top and bottom to scroll past the program groups one by one.

Windows 95 Rev C even came with IE4, however there was one trick. If you left the Windows 95 CD in the drive on the first boot, it’d pop up a box telling you that the install was not done, you’d click that away and IE4 Setup would do its damage. Eject the CD, and you were left with pristine Windows 95. Then when IE5 came around, it could safely be installed without it infecting everything.

Windows 2000

I never got hold of Windows 98 on my desktop, but at some point towards the very end of last century, I got my hands on a copy of Windows 2000 Release Candidate 2. My desktop was still a Pentium 133MHz, although it had 64MB RAM now and few more GB of disk space.

I loaded it on, and it surprised me just how quick the machine seemed to run. It felt faster than Windows 95. That said, it wasn’t all smooth sailing. Where was Network Neighbourhood? That was a nice feature of Windows 95. Ohh no, we have this thing called “My Network Places” now. I figured out how to kludge my own with the quick-launch, but it wasn’t as nice since applications’ file dialogues knew nothing of it.

The other shift was that Internet Explorer still lurked below the surface, and unlike Windows 95, there was no getting rid of it. My time using Linux had made me a Netscape user and so for me it was unneccesary bloat. Windows 2000 did similar Start Menu tricks, including “hiding” applications that it thought I didn’t use very often.

If it’s one thing that irritates me, it’s a computer hiding something from me arbitrarily.

Despite this, it didn’t take as long for me to adapt to it as I did from Windows 3.1 to 95 though, as the UI was still much the same. A few tweaks here and there.

In late 2001, my dinky old Pentium box got replaced. In fact, we replaced both our desktops. Two new dual Pentium III 1GHz boxes, 512MB RAM. My father’s was the first, with a nVidia Riva TNT2 32MB video card and a CD-ROM drive. Mine came in December as a Christmas/18th birthday present, with a ATI Radeon 7000 64MB video card and a DVD drive.

I was to run the old version of Windows NT 4.0 we had. Fun ensued with Windows NT not knowing anything about >8GB HDDs, but Service Pack 6a sorted that out, and the machine ran. I got Linux on there as well (SuSE initially) and apart from the need to distribute ~20GB of data between many FAT16 partitions of about 2GB each (Linux at this time couldn’t write NTFS), it worked. I had drive letters A through to O all occupied.

We celebrated by watching a DVD for the first time (it was our first DVD player in the house).

NT 4 wasn’t too bad to use, it was more like Windows 95, and I quickly settled into it. That said, its tenure was short lived. The momoent anything went wrong with the installation, I found I was right back to square one as the Emergency Repair Disk did not recognise the 40GB HDD. I wrustled up that old copy of Windows 2000 RC2 and found it worked okay, but wouldn’t accept the Windows 2000 drivers for the video card. So I nicked my father’s copy of Windows 2000 and ran that for a little while.

Windows XP was newly released, and so I did enquire about a student-license upgrade, but being a high-school student, Microsoft’s resellers would have none of that. Eventually we bought a new “Linux box” with an OEM copy of Windows 2000 with SP2, and I used that. All legal again, and everything worked.

At this point, I was dual-booting Linux and Windows 2000. Just before the move to ADSL, I had about 800 hours to use up (our dial-up account was one that accumulated unused hours) and so I went on a big download-spree. Slackware 8.0 was one of the downloaded ISOs, and so out went SuSE (which I was running at the time) and in went Slackware.

Suddenly I felt right at home. Things had changed a little, and I even had KDE there, but I felt more in control of my computer than I had in a long while. In addition to using an OS that just lets you do your thing, I had also returned from my OS travels, having gained an understanding of how this stuff works.

I came to realise that point-and-click UIs are fine when they work, hell when they don’t. When they work, any dummy can use them. When they don’t, they cry for the non-dummies to come and sort them out. Sometimes we can, sometimes it’s just reload, wash-rinse-repeat.

No more was this brought home to me when we got hold of a copy of Red Hat 8.0. I tried it for a while, but was immediately confronted by the inability to play the MP3s that I had acquired (mostly via the sneakernet). Ogg/Vorbis was in its infancy and I noticed that at the time, there didn’t seem to be any song metadata such as what ID3 tags provided, or at least XMMS didn’t show it.

A bit of time back on Slackware had taught me how to download sources, read the INSTALL file and compile things myself. So I just did what I always did. Over time I ran afoul with the Red Hat Package Manager, and found myself going in cycles doing many RPM solving dependency hell.

On top of this, there was now the need to man-handle the configuration tools that expected things the way the distribution packagers intended them.

Urgh, back to Slackware I go. I downloaded Slackware 9.0 and stayed with that a while. Eventually I really did go my own way with Linux From Scratch, which was good, but a chore.

These days I use Gentoo, and while I do have my fights with Portage (ohh slot-conflict, how I love you!!!), it does usually let me do what I want.

A time for experimentation and learning

During this time I was mostly a pure KDE user. KDE 2.0, then 3.0. I was learning all sorts of tricks reading HOWTO guides on the Linux Documentation Project. I knew absolutely no one around me that used Linux, in fact on Linux matters, I was the local “expert”. Where my peers (in 2002) might have seen it once or twice, I had been using it since 1996.

I had acquired some more computers by this time, and I was experimenting with setting up dial-up routers with proxy servers (Squid, then IP Masquerade), turning my old 386 into a dumb terminal with XDMCP, getting interoperation between the SCO OpenServer box (our old 486DX4/100MHz).

The ability for the Windows boxes to play along steadily improved over this time, from ethernet frames that passed like ships in the night (circa 1996; NetBEUI and IPX/SPX on the Windows 3.1, TCP/IP on Linux) though to begrudging communications with TCP/IP with newer releases of Windows.

Andrew Tridgell’s SAMBA package made its debut in my experimentation, and suddenly Windows actually started to talk sensible things to the Linux boxes and vice versa.

Over time the ability for Linux machines and Windows boxes to interoperate has improved with each year improving on the next layer in the OSI model. I recall some time in 1998 getting hold of an office suite called ApplixWare, but in general when I wanted word processing I turned to Netscape Composer and Xpaint as my nearest equivalent.

It wasn’t until 2000 or so that I got hold of StarOffice, and finally had an office suite that could work on Windows, Linux and OS/2 that was comparable to what I was using at school (Microsoft Office 97).

In 2002 I acquired an old Pentium 120MHz laptop, and promptly loaded that with Slackware 8 and OpenOffice 1.0. KDE 3.0 chugged with 48MB RAM, but one thing the machine did well was suspend and resume. A little while later we discovered eBay and upgraded to a second-hand Pentium II 266MHz, a machine that served me well into the following year.

For high-school work, this machine was fine. OpenOffice served the task well, and I was quite proficient at using Linux and KDE. I even was a trend-setter… listening to MP3s on the 15GB HDD a good year before the invention of the iPod.

Up to this point, it is worth mentioning that the Microsoft world, the UI hadn’t changed all that much in the time between Windows 95 and 2000/ME. Network Neighbourhood was probably the thing I noticed the most. At this time I was usual amongst my peers in that I had more than one computer at home, and they all talked to each other. Hence why Windows 95/98 through to 2000/ME didn’t create such an uproar.

What people DID notice was how poorly Windows ME (and the first release of 98) performed “under the hood”. More so for the latter than the former.

Windows XP

Of course I did mention trying to get hold of Windows XP earlier. It wasn’t until later in 2002 when the school was tossing out a lab of old AMD K6 machines with brand new boxes (and their old Windows NT 4 server for a Novell one) that I got to see Windows XP up close.

The boxes were to run Windows 2000 actually, but IBM had just sent us the boxes preloaded with XP, and we were to set up Zenworks to image them with Windows 2000. This was during my school holidays and I was assisting in the transition. So I fired up a box and had a poke around.

Up came the initial set up wizard, with the music playing, animations, and a little question mark character which at first did its silly little dance telling you how it was there to help you. Okay, if I had never used Windows before, I’d be probably thankful this was there, but this just felt like a re-hash of that sodding paperclip. At least it did eventually shut up and sit in the corner where I could ignore it. That wasn’t the end of it though.

Set up the user account, logged in, and bam, another bubble telling me to take the tour. In fact, to this day that bubble is one of the most annoying things about Windows XP because 11 years on, on a new install it insists on bugging you for the next 3 log-ins as if you’ve never used the OS before!

The machines had reasonable 17″ CRT monitors, the first thing I noticed was just how much extra space was taken up with the nice rounded corners and the absence of the My Computer and My Network Places icons on the desktop. No, these were in the Start menu now. Where are all the applications? Hidden under All Programs of course.

Hidden and not even sorted in any logical order, so if you’ve got a lot of programs it will take you a while to find the one you want, and even longer to find it’s not actually installed.

I took a squiz at the control panel. Now the control panel hadn’t changed all that much from Windows 3.1 days. It was still basically a window full of icons in Windows 2000/ME, albeit since Windows 95, it now used Explorer to render itself rather than a dedicated application.

Do we follow the tradition so that old hands can successfully guide the novices? No, we’ll throw everyone in the dark with this Category View nonsense! Do the categories actually help the novices? Well for some tasks, maybe, but for anything advanced, most definitely not!

Look and feel? Well if you want to go back to the way Windows used to look, select Classic theme, and knock yourself out. Otherwise, you’ve got the choice of 3 different styles, all hard-coded. Of course somewhere you can get additional themes. Never did figure out where, but it’s Gnome 1.0-style visual inflexibility all over again unless you’re able to hack the theme files yourself.

No thank-you, I’ll stick with the less pixel-wasting Classic theme if you don’t mind!

Meanwhile in Open Source land

As we know, it was a long break between releases of Windows XP, and over the coming years we heard much hype about what was to become Vista. For years to come though, I’d be seeing Windows XP everywhere.

My university work horses (I had a few) all exclusively ran Linux however. If I needed Windows there was a plethora of boxes at uni to use, and most of the machines I had were incapable of running anything newer than Windows 2000.

I now was more proficient in front of a Linux machine than any version of Windows. During this time I was using KDE most of the time. Gnome 2.0 was released, I gave it a try, but, it didn’t really grab me. One day I recall accidentally breaking the KDE installation on my laptop. Needing a desktop, I just reached for whatever I had, and found XFCE3.

I ran XFCE for about a month or two. I don’t recall exactly what brought me back to KDE, perhaps the idea of a dock for launching applications didn’t grab me. AfterStep afterall did something similar.

In 2003, one eBay purchase landed us with a Cobalt Qube2 clone, a Gateway Microserver. Experimenting with it, I managed to brick the (ancient) OS, and turned the thing into a lightish door stop. I had become accustomed to commands like `uname` which could tell me the CPU amonst other things.

I was used to seeing i386, i486, i586 and i686, but this thing came back with ‘mips’. What’s this? I did some research and found that there was an entire port. I also found some notes on bootstrapping a SGI Indy. Well this thing isn’t an Indy, but maybe the instructions have something going for them. I toiled, but didn’t get far…

Figuring it might be an idea to actually try these instructions on an Indy, we hit up eBay again, and after a few bids, we were the proud owners of a used SGI Indy R4600 133MHz with 256MB RAM running IRIX 6.5. I toiled a bit with IRIX, the 4DWM seemed okay to use, but certain parts of the OS were broken. Sound never worked, there was a port of Doom, but it’d run for about 10 seconds then die.

We managed to get some of the disc set for IRIX, but never did manage to get the Foundation discs needed to install. My research however, led me onto the Debian/MIPS port. I followed the instructions, installed it, and hey presto, Linux on a SGI box, and almost everything worked. VINO (the video capture interface) was amongst those things that didn’t at the time, but never mind. Sound was one of the things that did, and my goodness, does it sound good for a machine of that vintage!

Needless to say, the IRIX install was history. I still have copies of IRIX 6.5.30 stashed in my archives, lacking the foundation discs. The IRIX install didn’t last very long, so I can’t really give much of a critique of the UI. I didn’t have removable media so didn’t get to try the automounting feature. The shut down procedure was a nice touch, just tap the OFF button, the computer does the rest. The interface otherwise looked a bit like MWM. The machine however was infinitely more useful to me running Linux than it ever was under IRIX.

As I toiled with Debian/MIPS on the Indy, I discovered there was a port of this for the Qube2. Some downloads later and suddenly the useless doorstop was a useful server again.

Debian was a new experience for me, I quite liked APT. The version I installed evidently was the unstable release, so it had modern software. Liking this, I tried it on one of the other machines, and was met with, Debian Stab^Hle. Urgh… at the time I didn’t know enough about the releases, and on my own desktop I was already using Linux From Scratch by this time.

I was considering my own distribution that would target the Indy, amongst other systems. Already formulating ideas, and at one point, I had a mismash of about 3 different distributions on my laptop.

Eventually I discovered Gentoo, along with its MIPS port. Okay, not as much freedom as LFS, but very close to it. In fact, it gives you the same freedom if you can be arsed to write your own portage tree. One by one the machines got moved over, and that’s what I’ve used.

The primary desktop environment was KDE for most of them. Build times for this varied, but for most of my machines it was an overnight build. Especially for the Indy. Once installed though, it worked quite well. It took a little longer to start on the older machines, but was still mostly workable.

Up to this point, I had my Linux desktop set up just the way I liked it. Over the years the placement of desktop widgets and panels has moved around as I borrowed ideas I had seen elsewhere. KDE was good in that it was flexible enough for me to fundamentally change many aspects of the interface.

My keybindings were set up to be able to perform most window operations without the need of a mouse (useful when juggling the laptop in one’s hands whilst figuring out where the next lecture was), notification icons and the virtual desktop pager were placed to the side for easy access. The launcher and task bar moved around.

Initially down the bottom, it eventually wound up on the top of the screen much like OS/2 Warp 4, as that’s also where the menu bar appears for applications — up the top of the window. Thus minimum mouse movement. Even today, the Windows 7 desktop at work has the task bar up the top.

One thing that frustrated me with Windows at the time was the complete inability to change many aspects of the UI. Yes you could move the task bar around and add panels to it, but if you wanted to use some other keystroke to close the window? Tough. ALT-F4 is it. Want to bring up the menu items? Hit the logo key, or failing that, CTRL-ESC. Want to maximise a window? Either hit ALT-Space, then use the arrows to hit Maximise, or start reaching for the rodent. Far cry from just pressing Logo-Shift-C or Logo-Shift-X.

Ohh, and virtual desktops? Well, people have implemented crude hacks to achieve something like it. In general, anything I’ve used has felt like a bolt-on addition rather than a seamless integration.

I recall commenting about this, and someone pointing out this funny thing called “standardisation”. Yet, I seem to recall the P in PC standing for personal. i.e. this is my personal computer, no one else uses it, thus it should work the way I choose it to. Not what some graphic designer in Redmond or Cupertino thinks!

The moment you talk about standardisation or pining for things like Group Policy objects, you’ve crossed the boundary that separates a personal computer from a workstation.

Windows Vista

Eventually, after much fanfare, Microsoft did cough up a new OS. And cough up would be about the right description for it. It was behind schedule, and as a result, saw many cut backs. The fanciful new WinFS? Gone. Palladium? Well probably a good thing that did go, although I think I hear its echoes in Secure Boot.

What was delivered, is widely considered today a disaster. And it came at just the wrong time. Just as the market for low-end “netbook” computers exploded, just the sort of machine that Windows Vista runs the worst on.

Back in the day Microsoft recommended 8MB RAM for Windows 95 (and I can assure you it will even run in 4MB), but no one in their right mind would tollerate the constant rattle from the paging disk. The same could be said for Windows NT’s requirement of 12MB RAM and a 486. Consumers soon learned that “Windows Vista Basic ready” meant a warning label to steer clear of, or insist on it coming with Windows XP.

A new security feature, UAC, ended up making more of a nuisance of itself, causing people to do the knee-jerk reaction of shooting the messenger.

The new Aero interface wastes even more screen pixels than the “Luna” interface of Windows XP. And GPU cycles to boot. The only good thing about it was that the GPU did all the hard work putting windows on the screen. It looked pretty, when the CPU wasn’t overloaded, but otherwise the CPU had trouble keeping up and the whole effect was lost. Exactly what productivity gains one has by having a window do three somersaults before landing in the task bar on minimise is lost on me.

Windows Vista was the last release that could do the old Windows 95 style start menu. The newer Vista one was even more painful than the one in XP. The All Programs sub-menu opened out much like previous editions did (complete with the annoying “compress myself into a single column”). In Vista, this menu was now entrapped inside this small scrolling window.

Most of Vista’s problems were below the surface. Admittedly Service Pack 1 fixed a lot of the problems, it was already too late. No one wanted to know.

Even with the service packs, it still didn’t perform up to par on the netbooks that were common for the period. The original netbook for what it’s worth, was never intended to run any version of Windows, the entire concept came out of the One Laptop Per Child project, which was always going to be Linux based.

Asus developed the EeePC was one of the early candidates for the OLPC project. When another design got selected, Asus simply beefed up the spec, loaded on Xandros and pushed it out the door. Later models came with Windows XP, and soon, other manufacturers pitched in. This was a form factor with specs that ran Windows XP well, unfortunately Vista’s Aero interface was too much for the integrated graphics typically installed, and the memory requirements had the disk drive rattling constantly, sapping the machine of valuable kilojoules when running from the battery.

As to my run-in with Vista? For my birthday one year I was given a new laptop. This machine came pre-loaded with it, and of course, the very first task I did was spend a good few hours making the recovery discs then uninstalling every piece of imaginable crap that manufacturers insist on prebloating their machines with.

For what I needed, I actually needed Linux to run. The applications I use and depend on for university work, whilst compatible with Windows, run as second class citizens due to their Unix heritage. Packages like The Gimp, gEDA, LaTeX, git, to name a few, never quite run as effortlessly on Windows. The Gimp had a noticable lag when using my Wacom tablet, something that put my handwriting way off.

Linux ran on it, but with no support for the video card, GUI related tasks were quite choppy. In the end, it proved to be little use to me. My father at the time was struggling along with his now aging laptop using applications and hardware that did not support Windows Vista. I found a way to exorcise Windows Vista from the machine, putting Windows XP in its place.

The bloat becomes infectious

What was not lost on me, was that each new iteration of full desktops like KDE brought in more dependencies. During my latter years at University, I bought myself a little netbook. I was doing work for Gentoo/MIPS with their port of Linux, and thus a small machine that would run what I needed for university, and could serve as a test machine during my long trips between The Gap and Laidley (where I was doing work experience for Eze Corp) would go down nicely. So I fired off an email and a telegraphic money transfer over to Lemote in China, and on the doorstep turned up a Yeeloong netbook.

I dual booted Debian and Gentoo on this machine, in fact I still do. Just prior to buying this machine, I was limping along with an old Pentium II 300MHz laptop. I did have a Pentium 4M laptop, but a combination of clumsiness and age slowly caused the machine’s demise. Eventually it failed completely, and so I just had to make do with the PII which had been an earlier workhorse.

One thing, KDE 3.0 was fine on this laptop. Even 3.5 was okay. But when you’ve only got 300MHz of CPU and 160MB RAM, the modern KDE releases were just a bit too much. Parts of KDE were okay, but for the main desktop, it chugged along. Looking around, I needed a workable desktop, so I installed FVWM. I found the lack of a system tray annoyed me, so in went stalonetray. Then came maintaining the menu. Well, modern FVWM comes with a Perl script that automates this, so in that went.

Finally, a few visual touches, a desktop background loader, some keybinding experiments and I pretty much had what KDE gave me, that started in a fraction of the time, and built much faster. When the Yeeloong turned up and I got Gentoo onto there, the FVWM configuration here was the first thing to be installed on the Yeeloong, and so I had a sensible desktop for the Yeeloong.

Eventually I did get KDE 4 working on the Yeeloong, sort of. It was glitchy on MIPS. KDE 3.5 used to work without issue but 4.0 never ran quite right. I found myself using FVWM with just the bits of KDE that worked.

As time went on, university finished, and the part-time industrial experience became full-time work. My work at the time revolved around devices that needed Windows and a parallel port to program them. We had another spare P4 laptop, so grabbed that, tweaked Windows XP on there to my liking, and got to work. The P4 “lived” at Laidley and was my workstation of sorts, the Yeeloong came with me to and from there. Eventually that work finished, and through the connections I came to another company (Jacques Electronics). In the new position, it was Linux development on ARM.

The Windows installation wasn’t so useful any more. So in went a copy of the gPartED LiveCD, told Windows to shove, followed by a Gentoo disc and a Stage 3 tarball. For a while my desktop was just the Linux command line, then I got X and FVWM going, finally as I worked, KDE.

I was able to configure KDE once again, and on i686 hardware, it ran as it should. It felt like home, so it stayed. Over time the position at Jacques finished up, I came to work at VRT where I am to this day. The P4 machine stayed at the workplace, with the netbook being my personal machine away from work.

It’s worth pointing out that at this point, although Windows 7 had been around for some time, I was yet to actually come to use it first hand.

My first Apple

My initial time at VRT was spent working on a Python-based application to ferry metering data from various energy meters to various proprietary systems. The end result was a package that slotted in along side MacroView called Metermaster, and forms one of the core components in VRT’s Wages Hub system. While MacroView can run on Windows, and does for some (even Cygwin), VRT mainly deploys it on Ubuntu Linux. So my first project was all Linux based.

During this time, my new work colleagues were assessing my skills, and were looking at what I could work on next. One of the discussions revolved around working on some of their 3D modelling work using Unity3D. Unity3D at the time, ran on just two desktop OSes. Windows, and MacOS X.

My aging P4 laptop had a nVidia GeForce 420Go video device with 32MB memory. In short, if I hit that thing with a modern 3D games engine, it’d most likely crap itself. So I was up for a newer laptop. That got me thinking, did I want to try and face Windows again, or did I want to try something new?

MacOS was something I had only fleeting contact with. MacOS X I had actually never used myself. I knew a bit about it, such as its basis was on the FreeBSD userland, the Mach microkernel. I saw a 2008 model MacBook with a 256MB video device inbuilt, going cheap, so I figured I’d take the plunge.

My first impressions of MacOS X 10.5 were okay. I had a few technical glitches at first, namely MacOS X would sometimes hang during boot, just showing nothing more than an Apple logo and a swirling icon. Some updates refused to download, they’d just hang and the time estimate would blow out. Worst of all, it wouldn’t resume, it’d just start at the beginning.

In the end I wandered down to the NextByte store in the city, bought a copy of MacOS X 10.6. I bought the disc on April 1st, 2011, and it’s the one and only disc the DVD drive in the MacBook won’t accept. The day I bought it I was waiting at the bus stop, figured I’d have a look and see what docs there are. I put the disc in, hear a few noises, it spits the disc out again. So I put it back in again, and out it comes. Figuring this was a defective disc, I put the disc back in and march back down to the shop, receipt in one hand, cantankerous laptop in the other. So much for Apple kit “just working”.

Then the laptop decided it liked the pussy cat disc so much it wouldn’t give it back! Cue about 10 minutes in the service bay getting the disc to eject. Finally the machine reneged and spat the disc out. That night it tried the same tricks, so I grabbed an external DVD drive and did the install that way. Apart from this, OSX 10.6 has given me no problems in that regard.

As for the interface? I noticed a few things features that I appreciated from KDE, such as the ability to modify some of the standard shortcuts, although not all of them. Virtual desktops get called Spaces in MacOS X, but essentially the same deal.

My first problem was identifying what the symbols on the key shortcuts meant. Command and Shift were simple enough, but the symbol used to denote “Option” was not intuitive, and I can see some people getting confused for the one for Control. That said, once I found where the Terminal lived, I was right at home.

File browsing? Much like what I’m used to elsewhere. Stick a disc in, and it appears on the desktop. But then to eject? The keyboard eject button didn’t seem to work. Then I remembered a sarcastic comment one of my uncles made about using a Macintosh, requiring you to “throw your expensive software in the bin to eject”. So click the CD icon, drag to the rubbish bin icon, voilà, out it comes.

Apple’s applications have always put the menu bar of the application right up the top of the screen. I found this somewhat awkward when working with multiple applications since you find yourself clicking on one (or command-tabbing over to) one window, access the menu there, then clicking (or command-tabbing) to the other, access the menu up the top of the screen.

Switching applications with Command-Tab works by swapping between completely separate applications. Okay if you’re working with two completely separate applications, not so great if you’re working on many instances of the same application. Exposé works, probably works quite well if the windows are visually distinct when zoomed out, but if they look similar, one is reminded of Forrest Gump: “Life’s like a box of chocolates, you never know what you’re gonna get!”

The situation is better if you hit Command-Tab, then press a down-arrow, that gives you an Exposé of just the windows belonging to that application. A far cry from hitting Alt-Tab in FVWM to bring up the Window List and just cycling through. Switching between MacVim instances was a pain.

As for the fancy animations. Exposé looks good, but when the CPUs busy (and I do give it a hiding), the animation just creeps along at a snail’s pace. I’ll tolerate it if it’s over and done with within a second, but when it takes 10 seconds to slowly zoom out, I’m left sitting there going “Just get ON with it!” I’d be fine if it just skipped the animation and just switched from normal view to Exposé in a single frame. Unfortunately there’s nowhere to turn this off that I’ve found.

The dock works to an extent. It suffers a bit if you have a lot of applications running all at once, there’s only so much screen real-estate. A nice feature though is in the way it auto-hides and zooms.

When the mouse cursor is away from the dock, it drops off the edge of the screen. As the user configures this and sets up which edge it clings to, this is a reasonable option. As the mouse is brought near the space where the dock resides, it slowly pops out to meet the cursor. Not straight away, but progressively as the proximity of the cursor gets closer.

When fully extended, the icons nearest the cursor enlarge, allowing the rest to remain visible, but not occupy too much screen real-estate. The user is free to move the cursor amongst them, the ones closest zooming in, the ones furtherest away zooming out. Moving the cursor away causes the dock to slip away again.

Linux on the MacBook

And it had to happen, but eventually Linux did wind up on there. Again, KDE initially, but I again, found that KDE was just getting too bloated for my liking. It took about 6 months of running KDE before I started looking at other options.

FVWM was of course where I turned to first, in fact, it was what I used before KDE was finished compiling. I came to the realisation that I was mostly just using windows full-screen. So I thought, what about a tiling window manager?

Looking at a couple, I settled on Awesome. At first I tried it for a bit, didn’t like it, reverted straight back to FVWM. But then I gave it a second try.

Awesome works okay, it’s perhaps not the most attractive to look at, but it’s functional. At the end of the day looks aren’t what matter, it’s functionality. Awesome was promising in that it uses Lua for its configuration. It had a lot of the modern window manager features for interacting with today’s X11 applications. I did some reading up on the handbook, did some tweaking of the configuration file and soon had a workable desktop.

The default keybindings were actually a lot like what I already used, so that was a plus. In fact, it worked pretty good. Where it let me down was in window placement. In particular, floating windows, and dividing the screen.

Awesome of course works by a number of canned window layouts. It can make a window full screen (hiding the Awesome bar) or near full-screen, show two windows above/below each other or along side. Windows are given numerical tags which cause those windows to appear whenever a particular tag is selected, much like virtual desktops, only multiple tags can be active on a screen.

What irritated me most was trying to find a layout scheme that worked for me. I couldn’t seem to re-arrange the windows in the layout, and so if Awesome decided to plonk a window in a spot, I was stuck with it there. Or I could try cycling through the layouts to see if one of the others was better. I spent much energy arguing with it.

Floating windows were another hassle. Okay, modal dialogues need to float, but there was no way to manually override the floating status of a window. The Gimp was one prime example. Okay, you can tell it to not float its windows, but it still took some jiggery to get each window to sit where you wanted it. And not all applications give you this luxury.

Right now I’m back with the old faithful, FVWM.

FVWM

FVWM, as I have it set up on Gentoo

Windows 7

When one of my predecessors at VRT left to work for a financial firm down in Sydney, I wound up inheriting his old projects, and the laptop he used to develop them on. The machine dual-boots Ubuntu (with KDE) and Windows 7, and seeing as I already have the MacBook set up as I want it, I use that as my main workstation and leave the other booted into Windows 7 for those Windows-based tasks.

Windows 7 is much like Windows Vista in the UI. Behind the scenes, it runs a lot better. People aren’t kidding when they say Windows 7 is “Vista done right”. However, recall I mentioned about Windows Vista being the last to be able to do the classic Start menu? Maybe I’m dense, but I’m yet to spot the option in Windows 7. It isn’t where they put it Windows XP or Vista.

So I’m stuck with a Start menu that crams itself into a small bundle in one corner of the screen. Aero has been turned off in favour of a plain “classic” desktop. I have the task bar up the top of the screen.

One new feature of Windows 7 is that the buttons of running applications by default only show the icon of the application. Clicking that reveals tiny wee screenshots with wee tiny title text. More than once I’ve been using a colleague’s computer, he’ll have four spreadsheets open, I’ll click the icon to switch to one of them, and neither of us can figure out which one we want.

Thankfully you can tell it to not group the icons, showing a full title next to the icon on the task bar, but it’s an annoying default.

Being able to hit Logo-Left or Logo-Right to tile a window on the screen is nice, but I find more often than not I wind up hitting that when I mean to hit one of the other meta keys, and thus I have to reach for the rodent and maximise the window again. This is more to do with the key layout of the laptop than Windows 7, but it’s Windows 7’s behaviour and the inability to configure it that exacerbates the problem.

The new start menu I’d wager, is why Microsoft saw so many people pinning applications to the task bar. It’s not just for quick access, in some cases it’s the only bleeding hope they’d ever find their application again! Sure, you can type the name of the application, but circumstance doesn’t always favour that option. Great if you know exactly what the program is called, not so great if it’s someone else’s computer and you need to know if something is even there.

Thankfully most of the effects can be turned off, and so I’m left with a mostly Spartan desktop that just gets the job done. I liken using Windows to a business trip abroad, you’re not there for pleasure, and there’s nothing quite like home sweet home.

Windows 8

Now, I get to this latest instalment of desktop Operating Systems. I have yet to actually use it myself, but looking at a few screenshots, a few thoughts:

  • “Modern”: apart from being a silly name for a UI paradigm (what do you call it when it isn’t so “modern” anymore?), looks like it could really work well on the small screen. However, it relies quite heavily on gestures and keystrokes to navigate. All very well if you set these up to suit how you operate yourself, but not so great when forced upon you.
  • Different situations will call for different interface methods. Sometimes it is convenient to reach out and touch the screen, other times it’ll be easier to grab the rodent, other times it’ll be better to use the keyboard. Someone should be able to achieve most tasks (within reason) with any of the above, and seamlessly swap between these input methods as need arises.
  • “Charms” and “magic corners” makes the desktop sound like it belongs on the set of a Harry Potter film
  • Hidden menus that jump out only when you hit the relevant corner or edge of the screen by default without warning will likely startle and confuse
  • A single flat hierarchy of icons^Wtiles for all one’s applications? Are we back to MS-DOS Executive again?
  • “Press the logo key to access the Start screen”, and so what happens if the keyboard isn’t in convenient reach but the mouse is?
  • In a world where laptops are out-numbering desktops and monitors are getting wider faster than they’re getting taller, are extra-high ribbons really superior to drop-down menus for anyone other than touch users?

Apparently there’s a tutorial when you first start up Windows 8 for the first time. Comments have been made about how people have been completely lost working with the UI until they saw this tutorial. That should be a clue at least. Keystrokes are really just a shortened form of command line. Even the Windows 7 start menu, with its search bar, is looking more like a stylised command line (albeit one with minimal capability).

Are we really back to typing commands into pseudo command line interfaces?

The Command line: what is old is new again

The Command line: what is old is new again

I recall the Ad campaigns for Windows 7, on billboards, some attractive woman posing with the caption: “I’m a PC and Windows 7 was my idea”

Mmm mmm, so who’s idea was Windows 8 then? There’s no rounded rectangles to be seen, so clearly not Apple’s. I guess how well it goes remains to be seen.

It apparently has some good improvements behind the scenes, but anecdotal evidence at the workplace suggests that the ability to co-operate with a Samba 3.5-based Windows Domain is not among them. One colleague recently bought herself a new ultrabook running Windows 8.

I’m guessing sooner or later I’ll be asked to assist with setting up the Cisco VPN client and setting up links to file shares, but another colleague, despite getting the machine to successfully connect to the office Wifi, couldn’t manage to bring up a login prompt to connect to the file server, the machine instead just assuming the local username and password matched the credentials to be used on the remote server. I will have to wait and see.

Where to now?

Well I guess I’m going to stick with FVWM a bit longer, or maybe pull my finger out and go my own way. I think Linus has a point when he describes KDE as a bit “cartoony”. Animations make something easy to sell, but at the end of the day, it actually has to do the work. Some effects can add value to day-to-day tasks, but most of what I’ve seen over the years doesn’t seem to add much at all.

User interfaces are not one-size-fits-all. Never have been. Touch screen interfaces have to deal with problems like fat fingers, and so there’s a balancing act between how big to make controls and how much to fit on a screen. Keyboard interfaces require a decent area for a keypad, and in the case of standard computer keyboards, ideally, two hands free. Mice work for selecting individual objects, object groups and basic gestures, but make a poor choice for entering large amounts of data into a field.

For some, physical disability can make some interfaces a complete no-go. I’m not sure how I’d go trying to use a mouse or touch screen if I lost my eyesight for example. I have no idea how someone minus arms would go with a tablet — if you think fat fingers is a problem, think about toes! I’d imagine the screens on those devices often would be too small to read when using such a device with your feet, unless you happen to have very short legs.

Even for those who have full physical ability, there are times when one input method will be more appropriate at a given time than another. Forcing one upon a user is just not on.

Hiding information from a user has to be carefully considered. One of my pet peeves is when you can’t see some feature on screen because it is hidden from view. There is one thing if you yourself set up the computer to hide something, but quite another when it happens by default. Having a small screen area that activates and reveals a panel is fine, if the area is big enough and there is some warning that the panel is about to fly out.

As for organising applications? I’ve never liked the way everything just gets piled into the “Programs” directory of the Start Menu in Windows. It is just an utter mess. MacOS X isn’t much better.

The way things are in Linux might take someone a little discovery to find where an application has been put, but once discovered, it’s then just a memory exercise to get at it, or shortcuts can be created. Much better than hunting through a screen-full of unsorted applications.

Maybe Microsoft can improve on this with their Windows Store, if they can tempt a few application makers from the lucrative iOS and Android markets.

One thing is clear, the computer is a tool, and as such, must be able to be adapted for how the user needs to use that tool at any particular time for it to maintain maximum utility.
