Migrated to Wordpress

I've abandoned Blogger.com in favour of Wordpress. You can see my new blog (with all of this blog's posts) at sinewalker.wordpress.com

Later (2015): I migrated from Wordpress to my own personal domain: milosophical.me

Why have I done this?
  1. Nobody actually reads this blog besides me (I think) so it won't inconvinience anyone
  2. Blogger is good, but it has some limitations with post formatting and doing out-of-the-ordinary things. I find I need to work around Blogger too much. Wordpress is more hackable
  3. Features such as Categories (tags) and link-rolls are not built-in, so I need to do some crufty hacks and maintain two different Delicious accounts, where I'd rather just have one. Wordpress has these extra features built in
  4. Wordpress converts emoticons. I like that :-)
  5. I can ultimately host my blog on my own server with Wordpress (currently I'm using Wordpress' free hosting at wordpress.com)
  6. Wordpress is open-sourced, Blogger is Google. This doesn't really bother me politically, but I do like the idea that I can take my blog with me with Wordpress, whereas with Blogger, my blog depends on Google's fortunes. While betting on Google is pretty-much a sure thing, you never know... ;-)
  7. Migrating to Wordpress was mostly painless. It even fixed up the problem I've had with Flickr posts, where the citations drop off if I add my own “Filed in” division
So, if you've been reading my blog, thanks! It's not over, I'm still blogging at wordpress now.

Dvorak keyboards


I prefer Dvorak keyboards to QWERTY, which confounds my work colleagues no end :-)

I've been typing on Dvorak for about 3 years now. The main reason I use the Dvorak keyboard layout is because, after 15 years of six-finger typing on QWERTY, I decided to learn to touch-type, and Dvorak is very easy to learn (I learnt it in 2 weeks, back to my old typing speed after a month).

I don't believe Dvorak makes me a faster typist inherently (though I am faster now that I can touch-type), but it's much more comfortable and the shooting pains in my arms have gone.

At home, I use a slightly older model of the A4 KB(S)-2350ZRP (pictured). I chose this keyboard over more radical designs that I like, because the A4 2350 is not too different from a stardand typewriter layout — so it plays nice with other people in the family. The A-shaped keys help a lot with my lower-arm pains too, but not so much as the Dvorak layout, since most of the time I'm typing at work on a standard Dell SK-8125.

Making up strong passwords with this keyboard layout is much easier now. Think of a fairly good password (fee1bo7ch, for instance) and then type it on Dvorak as-if you were typing on QWERTY (becomes u..1br7jd).

I'm thinking about teaching my left hand to type one-handed dvorak too, to improve my mousing experience.

Issues I've encountered with Dvorak

There are some minor annoyances when you switch away from QWERTY. Anybody in a minority group (such as left-handed people) will identify with some of these. None of these issues have been serious enough to cause me to switch back to QWERTY though, as the benefits I've gained (typing speed, no more pain) far outweigh any of them, even all considered together.
  • Typing on someone else's QWERTY keyboard becomes very uncomfortable. I frequently shudder at the thought of having to touch someone's keyboard now (not because of hygene, but it's the same feeling). I can still do it, and since I never learnt to type properly on QWERTY anyway, it's no trouble to look at the keyboard. Years of familiarity with this layout means I don't need much reminding, so it's not like I have to hunt for keys, more like a mental changing of gears and putting up with awkward key combinations (like, for instance A-W-K-W-A-R-D)
  • In the same vein, letting someone else use your keyboard can be fun! Most operating systems allow an easy/quick way to switch layouts. Windows sort-of does, but it only applies to the current window, not the whole system (what a stupid design!), so you need to remember that gotcha. I sometimes use this as an opportunity to advocate Dvorak, but usually this is interpreted as “just Mike evangelising again…” ;-)
  • Some programs and games make use of the QWERTY layout in selecting keyboard short-cuts. For example, vi uses the H J K and L keys for cursor movement, since this arrangement is sensible in QWERTY. On Dvorak, it's usless as those keys are located at the J C V and P positions. But then again, vi sucks anyway, so it's not a problem. Winamp uses Z X C V and B for pause, playback and track selection functions, but it can be re-programmed, at least for the global shortcuts. Some games suffer, so you need to switch back to QWERTY for them
  • Passwords can be tricky. On systems that lock your account after too many bad tries, you have to be very confident that you know where the keys are! An alternative is to use my password trick above, and always look at the keys when entering passwords. This is accurate, but if you need to put in your password on a QWERTY keyboard, you have to know the real password, and not the easier QWERTY–Dvorak mapping you have memorised

New blog stuff, and issues

I've recently added blogging tags to my blog, courtesy of Userscripts.org and Greasemonkey for Firefox.

Unfortunately, it (or the way I've put it in my template) appears to have a conflict with Flickr's BlogThis feature, such that the image citations are hidden when the posting is viewed… not sure what's causing it or how to fix yet.

So, if you're the owner of some flickr photo's that I've blogged and wonder where the citations are, then I'm sorry, they get hidden as soon as I tag my post, and I'm working on how to restore them. In the mean-time, clicking the picture does still take viewers to your page, so they can view the actual owner details from there.

Organised books



Wouldn't it be nice to organise your books like this?

Only, you'd have to have some sort of catalogue with the book's colour to be able to find anything (probably use LibraryThing and add a colour tag).

Still, it looks nice.

Crashed Linux


Crashed Linux
Originally uploaded by milliped.
This is a pretty neat shot of the in-flight entertainment system on an Airbus A330 having a boot-up issue. Note, the kernel is Linux.

This photo has a big rant in the flickr comments about whether or not it's a Linux crash. Well, what's a Linux crash? Most of the public Windows crashes do not involve the Windows kernel (except for blue-screens) but they get called Windows crashes. So, to be fair, this is a Linux crash, even if it appears that the kernel itself is fine.

Shifting Interfaces

Once again, Microsoft have drastically changed their Office interface.

While the new interface is very nice eye-candy and probably has some new features that could help (arguably), it represents yet another need to re-train.

The old argument that OpenOffice is too different from MS-Office to be quickly useable has just vanished. OpenOffice is more like MS-Office 97 than MS-Office 2007 will be, and really, who has needed any of the features in Office XP or Office 2003? What were they, again…? Oh yeah, anoying interface changes, and removal of the stupid Paperclip.

I think I'll be distributing my work documents in PDF, created by OOo now, except where I must absolutely use MSO documents for work. Everthing else will be OOo. Now I just need to convince my wife that it's not worth continually purchasing MSO, or even having it on our home PC.

Using punctuation entity names in XHTML

You can use the following XHTML entity names to put propper punctuation symbols into your web pages.

The W3C maintains a complete list, though finding what you need can be a bit tricky. I'm working on a complete list that actually displays the characters together with the other detail from W3C's table, a lot neater coding than this Blogger post too, I hope…

In the mean-time, here's a short-list of common characters that I use quite a lot:

Double quotes: “ ” ⇒ use ldquo and rdquo
Single quotes: ‘ ’ ⇒ use lsquo and rsquo
Ellipsis: … ⇒ use hellip
En-dash: – ⇒ use ndash
Em-dash: — ⇒ use mdash
Minus sign: − ⇒ use minus

Multiplication: × ⇒ use times
Division: ÷ ⇒ use divide
Approximately equal: ≈ ⇒ use asymp

Trade Mark: ™ ⇒ use trade
Copyright: © ⇒ use copy
Registered: ® ⇒ use reg

New Printer “Just Works” in SUSE 10

Well, here's a first for me: go to local Dick Smith's, buy a cheap printer, for my wife (HP Deskjet 3940, AU$66). Because I don't really care about printing from Linux, I didn't care if it works or not on that OS, just bought whatever Windows printer was cheapest.

Brought it home, plugged it into my PC (in Windows) and it works, after installing drivers and software and about 15 mins of setup time.

For the heck of it, I rebooted to Linux to see what would happen. Well lordy “New hardware detected: HPdeskjet3940” and an offer to set it up. After 5 minutes — just accepting all the standard options — out comes a test page, in colour, bi-directional and fast.

Neat. Linux is ready for me....

?? New template doesn't work ??

New del.icio.us rolls do not appear at right-hand side of this site, even though they did in Preview? Strange. Maybe it's a blogger glitch? See what happens in a few days, I suppose...

UPDATE: 2006-03-20 12:45 -- Not a glitch. Strange behaviour when I commented the del.icio.us block in the template. It seems that the comment block wasn't terminated? Odd. Fixed by removing my comments. This is sub-optimal, but works at least.

Organising my bookmarks

I've added the new “tag roll” and “link roll” to the right in this blog's template. Looks great, but examining my tags reveals I'm a bit disorganised, huh?

That's nothing, you should check out my tags in Flickr. Definitely could do with some improvement there.

Tags are a great idea. The trouble is, I'm uncertain how best to use them. That is, what are the best tag words to attach to a link or photo so that I can find the right one again? How can I best group my del.icio.us tags into Bundles to facilitate research? Should I even try?

I guess only experience will help. So I'll keep persevering :-). Also, since tags are social, looking at how other people have tagged their stuff could be instructive too.

Alternatives for data transmission in over-secured areas

The IETF (Internet Engineering Task Force) is the international community of network experts who have been designing the main Internet “standards” for the past 30 years or so. These include such landmark standards as RFC822 (email) and RFCs2045-2047 (MIME). New standards continue to be published and implemented today.

Two IETF contributions may be especially helpful for our current issues at work in transferring data between two isolated systems. For the published IETF documents, see:
(please note the publication dates when reviewing these recommendations)

Of special note: RFC1149 has been implemented in Bergen, Norway: http://www.blug.linux.no/rfc1149/

DVD-CSS in SUSE

There are excellent instructions for installing/patching SUSE to play commercial (CSS encrypted) DVDs. I had no trouble following them either. Wonder of wonders.

The whole issue of libdvdcss being “illegal” in DMCA-enlisted countries seems to be mute now, from my perspective... so long as your intent is only to watch movies that you have legally obtained (and not fincancial gain), then it should be fine — if it's good enough for the MPAA, then it's good enough for me. This would seem to me to work well with Australia's existing copyright law, which specifically grants fair-use copying and playing anyway, and goes against the dogma of the DMCA.
