Pwned!

Smashed laptop screen

Tonight’s romantic task, once Jane had returned home from a lecture at Glasgow Caledonian University, was to back-up Jane’s Mum’s laptop. Which, as you can see from the photograph, has a somewhat pwned screen!

And in case you were wondering, yes we did try that technical support favourite of switching it off and switching it back on again, but it didn’t fix the problem with the screen.

It gets returned to Hi-Grade UK tomorrow for some cosmetic surgery and a screen transplant.

Wanted: new PC system without Windows Vista

Computer system with three monitors

I’m now officially™ on the market for buying a new computer system, ever since the Saunders’ household Director of Finance gave the thumbs up to my application last week. The thing is now is not necessarily the best time to be looking for new hardware. Not because there isn’t any cool gear out there just now (see Intel Core 2 Duo CPU, Creative X-Fi soundcard, and the latest graphics card chipsets from nVidia and ATi for details); it’s not the hardware that’s the problem, it’s the software.

On January 30 Microsoft’s latest operating system, Windows Vista, was released to the public (it having already gone live to businesses at the back-end of 2006). But I don’t want it. I don’t want to ‘upgrade’ to this massively bloated, unnecessarily resource-hungry operating system. It might look glitzy and shiny, packed with Web 2.0-esque gradients, rounded corners and reflections but I don’t want it. I’m happy with Windows XP, thank you very much.

Windows Vista hardware requirements

The above image was shown to me by a friend earlier today. It just about sums up the problem with Vista. It’s from the Dell website and explains simply what different hardware configurations can achieve under Windows Vista. Dell have defined three categories depending on your hardware:

  1. Good: Windows Vista Capable
  2. Better: Windows Vista Premium Ready
  3. Best: Dell Recommended (in other words, more than enough)

And as is says:

Windows Vista Capable is great for … booting the Operating System, without running applications or games.

Hmmm … so if my hardware is Windows Vista Capable then that means I can boot into Windows but won’t necessarily be able to run anything on it! Which is a bit like having a car that you can sit in but won’t actually go anywhere. A bit like a sofa.

Any recommendations

So, I’m looking for a new system any recommendations on companies that I might try? I’d like roughly the following spec:

  • Having always used AMD CPUs, I wouldn’t be adverse to an Intel Core 2 Duo
  • 2 GB RAM (at least — I wouldn’t turn my nose up at 3 or 4 GB)
  • Powerful graphics card — I’d prefer an ATi rather than nVidia — enough to run modern games on it. By which I really mean Battlefield 2 and Battlefield 2142, and which can support two monitors (CRT or LCD).
  • At least 500 GB hard drive — SATA
  • Dual Layer DVD writer
  • Space on the motherboard to install my Creative Soundblaster X-Fi soundcard
  • If possible, one old-school COM/Serial port for my beloved Psion PDA.

Any thoughts? So far I’ve been looking at PC Specialist and Cube 247. If you were to buy something today where would you go? (I’m hoping to buy sometime in the next month or two.)

Why web standards matter

These last couple of weeks I’ve spent much of time, both at home and work, puzzling over a coding project I’m currently working on at the University; which is partly why my blogging activity has been more intermittent than usual.

Baseline browsers

For this particular project we set a baseline of which browsers we would support, based in part from the visitor information we gather on the University’s homepage. This collects information about which browsers are being used, the user’s screen resolution and the number of colours their computer will support; no personal information is gathered. Having examined this data we decided to support Safari (Mac OS X), Internet Explorer 6 and 7 (Windows), Mozilla Firefox (Windows, Mac and Linux) and Opera 9 (Windows, Mac and Linux).

What happens when you have to support IE6

That we have to support IE6 — because many of the PCs at the University run Windows 2000 which will not run the newer IE7 — has had a serious impact on our coding time. Here’s what happens on a typical day as I work through our specifications list:

  1. I spend maybe 30-60 minutes coding one particular aspect of the site, e.g. page layout, using standards-compliant CSS.
  2. I test it in Firefox 2 – it works.
  3. I test it in Opera 9 – it works.
  4. I test it (by sending the code to colleagues) in Safari and Linux Konqueror – it works
  5. I test it in IE7 – it (usually) works.
  6. I test it in IE6 … and then say something like “Oh dash it!”
  7. I spend anywhere up to 3 or 4 hours ‘debugging’ it to find out exactly why IE6 won’t render the page correctly. This usually involves either adding an additional CSS statement (e.g. width: 200px;) or completely rewriting the code from scratch.
  8. Repeat with the next element on my project spec.

As you might imagine, this can get quite tedious.

Acid2 Browser Test

The problem lies in the way that different browser manufacturers have interpreted the web standards as laid down by the World Wide Web Consortium (W3C). These standards, published as W3C Recommendations, are guidelines for, amongst others, browser software developers so that they know how their products should properly render web pages.

And as you might guess, some are better than others. Some follow the rules closely; others are a little more relaxed. And to test how compliant a particular browser is the kind folks at the Web Standards Project have provided an online ‘acid test’, called the Acid2 Browser Test. Using XHTML and Cascading Style Sheets — so no graphics, just div tags and background colours, and stuff™ — it tries to display a smiley face with the words “Hello world” above it.

Acid2 Browser Test results

Here is how the four Windows browsers I mentioned before (Firefox, IE7, IE6 and Opera 9) fare with the Acid2 test:

Firefox 2

Firefox tries the Acid 2 test and almost passes

As you can see Mozilla Firefox does not too badly. At least, it looks sort of like a face, even it is wearing a mask. If it were a film it would probably be Girl Interrupted.

Gran Paradiso (Firefox 3) Alpha 2

Firefox 3 passes the Acid2 test

Thankfully the core layout code has been rewritten for Firefox 3 (currently in Alpha) which fixes the problems evident in Firefox 2’s rendering of the Acid2 page.

Internet Explorer 6

IE6 fails the Acid 2 test

The troublesome Internet Exploder 6 utterly decimates the page. It should perhaps be renamed Internet Exploder and left in a drawer to gather dust. Would you believe this is the world’s most popular browser? Look what it has done to some nice programmer’s code! If it were a film it would probably be [insert name of gore-fest horror pic here].

But worry not, Microsoft improved things and released …

Internet Explorer 7

IE7 tries the Acid 2 test and fails spectacularly

The latest (and greatest?) version of the mighty Microsoft’s browser, Internet Explorer 7, which erm … well, to be honest, fares only a little better than its little brother (browther?). If it were a film it would probably be the sequel to [insert name of gore-fest horror pic here]!

Opera 9

Opera 9 passes the Acid 2 test and shows a smiley face and Hello World!

And then Opera 9 steps up to the plate and delivers 100%. That is how the page should look. If it were a film it would be your favourite feel-good movie, one that you could watch day-in, day-out. Lovely.

Konqueror (Linux)

Konqueror passes the Acid 2 browser test

And since I know you’re all wondering the same thing: “But how well does the Linux browser Konqueror do on the Acid 2 Browser Test?” I’ll tell you. It passes with flying colours too. (Thanks to Mike for the image.)

Safari (Mac OS X)

Safari passes the Acid 2 test

And good old Apple also manage to get their browser to pass the Acid 2 Browser Test with their Safari browser. (Thanks to “a mate” of Mike for this screenshot.)

The moral of the story

Imagine if your tv did this to the programs, videos or DVDs you watched. Viewers wouldn’t stand for it. So why do web users stand for it?

The moral of the story is don’t use Internet Explorer, use something better. I can thoroughly recommend both Firefox and Opera, which I’ve been using for a good few years now.

If you like customizing your software, with various add-ons, then choose Mozilla Firefox. If you just like a fast, attractive browser that shows things the way they should look then download and install Opera 9.

If you’re using Mac OS X then you are probably using Safari already, which I believe is pretty cool. And if you are using Linux then you’ve probably already compiled the Konqueror source code and installed it on your über-geeky homemade distro yourself, and I’m preaching to the converted!

You know it makes sense.
