I’ve earlier written a norwegian piece on why Vista isn’t coming near my computer over at Nettvint.net, but since the arguments have grown during time and I felt the need for a recap, I’ll do it again.
To sum it up: Vista isn’t coming near any of my computers, and I’ll tell you why right here and now:

My pet peeve regarding usability is the lack of (let’s face it, most) developers ability to put themselves in the situation of computer beginners (aka newbs). Eric S. Raymond describes exactly how bad this can get in The Luxury of Ignorance. And in my own opinion, this also describes why Linux is still miles away from being a viable desktop alternative for the regular Joe. I’ve had too many similar encounters like this myself.
A key point in understanding users is also discussed in Raymond Chen’s The default answer to every dialog box is “cancel”. Nice to see that Microsoft has people around that realizes this. Now if they could only understand that the default answer to security alerts is “allow” as well (atleast after the users learn what cancel does to them), they’d probably understand why those are useless aswell. ;)
Todays lesson? People shouldn’t need to read manuals to get things working, and they don’t read dialog boxes. I’ve always meant that any piece of software should be so straight forward that the manual becomes redundant.

Just to state some basic facts…
- Flash doesn’t work _everywhere_, unlike normal HTML. My computer runs a 64-bit OS without 32bit emulation, and Adobe has yet to provide a Flash player for any 64-bit platform.
- Flash requires a proprietary plugin.
- Flash does not let users change font sizes or contrast settings using personalized stylesheets.
- A lot of screenreaders and other accessibility tools does not work with Flash (some screenreaders does using a Windows-specific API).
- Flash is not indexable by all search engines. Some does index text in Flash files, but since there is no way to link to the subpage your query was found in, people can’t be redirected to the result, making the result useless for users.
- If a browser doesn’t support Flash, you get nothing unless the entire website is also saved in a standard compliant (also know as HTML) way. If a browser doesn’t support CSS, you will still get a readable website.
- Flash doesn’t not present my usual OS widgets (textfields, submit buttons and such) or use my OS settings for these (larger fontsizes, higher contrast and such).
- Flash is owned by a commercial entity and even though the format specification is open, it is not licensed for free use.
- Flash sites breaks the back button, a fundamental function that users are used to.
- There is no way to bookmark a subpage of most Flash-only sites.
- Flash doesn’t work in most alternative browser devices, like PDAs or Smart phones.
- Printing content from a Flash site is extremely difficult and most of the time comes out weird on paper, if at all.
Flash doesn’t provide a standard way of navigating without the mouse (tab navigation is possible by default).
Note: I’m not saying Flash should be banned from the net, I think there are numerous valid reasons to use Flash. But my opinion is that it should only be used for interactive multimedia which cannot be represented in HTML/CSS/JS in an easy way. Stuff like games, ads and (because of terrible object tag support in browsers) video playback. If you need to use Flash to have graphical menu buttons with mouseovers or display a logo in the header of your site you really should reconsider your profession. :)

Since I’m tired of Googling it up every time I need the link, I thought I’d just post it here. Seybold tells you why tables for layout is stupid.

Via Learn Out Loud you can read about why DRM is a bad, bad thing… And for the less technical of my readers, DRM is the copy protection on all music bought online from MSN (for your Zune player) or iTunes (for the iPod). This is a must read, the end of the article contains a lot of tips on where to get music without DRM, even cheaper than MSN and iTunes!

When I first got a customized Firefox install demonstrated to me I was immediately awestruck by the functionality offered by extensions. Sure, Firefox isn’t the fastest nor the most standard-compliant browser around, but the extensions really got me hooked (thanks, HHJ)! So I did the conversion after having used Opera for 5-6 years. And now, after half a year I find it a real pain to install all extensions every time I install a new computer. So as much for the benefit of myself as well as a public service, I thought I’d list all my extensions together with links. :)

Today I stumbled upon an article by Lachlan Hunt which lists some of the problems with using XHTML for webpages. After having read through it, I was nearly ready to reimplement my XHTML pages in HTML… The main cause for this was IE’s lack of support for application/xhtml+xml content. It won’t render it, but instead provides you with a standard download dialog. Serving XHTML as text/html, like most people do nowadays is actually fooling older user agents (like IE) to treat the page as good ole’ HTML. But there were a lot of other issues with XHTML I didn’t like the sound of either.
This would actually make my employer have to use HTML Transitional, since some of the ad serving is done using <iframe>, which isn’t allowed in the strict doctypes. You can read more on the differences between strict and transitional markup here. I might be arrogant, but HTML4 Transitional sounds a bit too nineties for me to accept, even if it is an acknowledged standard. ;-)
Luckily, the XHTML specs states that text/html is ok to use for XHTML documents, and they even included a thorough appendix on how to make sure your XHTML document renders correctly in browsers that treat it like HTML. Very good reading, and it contained several implications I weren’t aware of!
Edit 1: There’s an article over at workingwith.me.uk about sending mime headers depending on what the user agent supports. Highly recommended reading. Works like a charm here. :) Though I was a bit shocked to notice that W3C’s validator doesn’t send the correct ACCEPT-headers.
Edit 2: W3C has a table with the definitive overview of contenttypes for the differenct specs.
Edit 3: The code from www.workingwith.me.uk har some bugs if a browser explicitly states it does NOT want application/xhtml+xml. I rewrote my handling using some code from www.autisticcuckoo.net which seems to work more reliably (setting Q to 1 as default).

Lately I’ve done some research for free (as in beer) development environments, both for web and Java. The result was, to put it blunt, a huge disappointment. What actually disappointed me more, was the horrible pricing for commercial solutions with no “personal use only” licenses available.
The “can do everything known to man but is like removing a lash in the eye with a shovel”-approach would ofcourse be Eclipse or Netbeans, but after using them for a couple of days you loose all faith in using Java for creating large desktop applications. They’re essentially large and fancy texteditors with the possibility of launching external compilers. Why this task should need to require the good half of my 1 GB RAM is totally beyond me… Add to this a startup-time that matches that of the OS itself, and your productivity probably needs to be picked up from the floor by the time you’re ready to do some actual programming.
For smaller things I’ve found myself using Notepad++ lately, and while it lacks a lot of automation it’s still the best Notepad replacement I’ve seen, so I advice you to give it a try none the less. But I was stilling missing some things in order to use it as a full IDE so I set out to test the competition. My wishlist went something like this:
- Open-source and actively developed
- Syntax highlighting
- Project- or filebrowser panel
- Some sort of context-sensitive lookup
- FTP support for web development
- Shortcuts for build/run/preview
- Should support the languages I use most (XML, Java, JSP (this one’s surprisingly rare!), PHP, HTML, CSS, JS and ideally Python)
- Subversion support
I don’t think I’m particularily picky, so why were there so few programs that managed to fill half of these? I have no idea myself, but the only one that fitted the bill for me was PSpad. It supports a ton of languages, but lets you define compilators, run commands and preview commands for each one yourself. The only things missing from my list are opensource (it’s closed but still freeware) and SVN support. But SVN updating isn’t something you do continously anyway, so TortoiseSVN does the job fine for now. In addition you get macro support, chm-file help integration, class browser for several languages, integration against TopStyle CSS editor, direct FTP edit, template library, hex edit, export with highlight to RTF or HTML, HTML processor (tidy up or just compress), internal webbrowser and more. This one is truly my recommended download of the day! :)

After Microsoft pushed the Windows Genuine Advantage Notification (hereafter refered to as WGAN) tool out using Windows Update a lot of people cried out in despair. While I actually sympathize with Microsoft for trying to protect their intellectual property, there were several things that didn’t quite sound right:
- Microsoft originally assured the press that the tool could easily be uninstalled, but this was clearly not the case.
- Without mentioning it in any documentation WGAN send information about you and your computer to Microsoft once a day.
- Microsoft itself states in the user-agreement that WGAN is beta software. Forcing users to install beta software doesn’t sound like anything a qualityminded software company would do. The fact that many people has received false notifications underscores this fact.
- The description of Automatic Update clearly states that it only installs high-priority updates crucial for the security of your computer, but this is clearly not how anyone would describe WGAN.
Luckily, I have set Automatic Update to notify me before installing any updates, and I always select custom install so I can review the updates prior to installing them. This made me able to unselect WGAN for installation. Therefore my laptop is still free from spyware and beta software. I strongly advice everyone to do the same.
If however, you were one of the unlucky ones to get this piece of deceitful software on your system, I have the cure for you. Firewallleaktester.com has made a utility called RemoveWGA which helps you remove the update from your system.

In my earlier days (before I switched from Opera to Firefox, now I use the AdBlock Plus Firefox extension to block ads) I used to surf the web with Flash disabled. I was actually quite shocked to notice how many websites that just didn’t display anything when read though a browser without Flash support. This might be fixed by what I am about to discuss here, but it’s not my main point.
Have you ever tried validating a page with Flash in it? Chances are it didn’t validate. Even Adobes official material on how to embed Flash encourages use of the <embed> tag, which is not a valid tag in any of the W3C specs for markup languages on the web. It’s a Netscape invention, and it actually took quite some time until the Mozilla-based browsers managed to support the <object> tag in a satisfactory fashion. Frustrated with this fact, I started Googling, and this opened up a can of worms, as Internet Explorer didn’t fully support the <object> tag in a standard-conforming way either…
All I really wanted was a way that…
- Was completely valid (X)HTML.
- Sent the user to the Flash download center if the Flash plugin is missing or out of date.
- Didn’t use the IE-specific conditional construct <!–[if !IE]> <–> (I don’t like browser-specific coding, even if it doesn’t break the standard).
