Technology is accelerating

As Ray Kurzweil says, (information) technology is accelerating.  This is great but increasingly we are seeing devices turning obsolete faster than ever.

Who want's to get CRT tv, anymore - even if it was free?Why would I want to buy a motorcycle that doesn't have fuel injection?Would you want a 3 year old cell phone? When you watched a movie on TV, for the longest time, it was difficult to tell which decade it was filmed in.  You sometimes noticed when there were k-cars on the road and the movie wasn't trying to be set in the 80's.  But once computers and cell phone started appearing then you could tell quite quickly what decade, even what year the movie was probably made. What worries me is the change of more expensive technologies in the future:My car is obsolete because it doesn't have fulltime internet access or because it doesn't self drive.My house is obsolete because it isn't smart or is too far in the countryside for high speed internet.My city is ob… homepage back up

My old web page had been down for more than a year.

It had used an old version of TurboGears which eventually my provider stopped supporting and then finally last month my account expired and I didn't renew.
So it was really without a home.  This weekend I decided that I should put it back up.  It's been pretty good to me, it got me this great job because they found my resume on my site.

As I got the old files I found that I actually had more than 3 versions of the site.  The very first one was using Microsoft FrontPage.  My backup was littered with .htm files.

Later I had used PHP, and quite a bit. It's interesting how I used PHP more as programming language and less as a templating language.  It was difficult to understand how the site looked, it was all code and functions.  I had to use the Wayback Machine to find out what it really looked like.

Finally I had used Python and TurboGears.  After that I pretty much left alone, until now.

Since I like learning …

Hello Streetview

Hello streetview, how are you doing?

Vanity URL

Finally decided to buy for my vanity URL, why not?

It points to my blog.instead of the less memorable and paying for 5 years is relatively cheap.

Key-Train Launched

In the spirit of "Release Early/Release Often" I've shipped the first version of key-train (

Here's a screenshot:

Features include:Training for all the lowercase keys on the main part of the keyboard in two languages (English/Brazilian Portuguese) and two keyboards (qwerty/ABTN).  More languages and keyboards should be easy to add.Easy for others to contribute better lessons and new keyboards.Easy for others to translate the software using the standard gettext package (I recommend using poedit). The key-train.pot file is created automatically - so don't edit it.  For your language, you would create a .po file like, this one.A reasonable progression of keys and training (27 lessons).Speed and accuracy training by typing in parts of Wikipedia articles.Only one lesson file is required for different languages and keyboards.But the program isn't complete, here's a list of the biggest problems:The package is way too big, I have to split out …

fsck'd my drive

After a few power failures during a week of storms I rebooted my Ubuntu Linux computer and fsck found some errors. Next time I booted it found (and corrected) even more errors, until, eventually I wasn't able to boot anymore (couldn't find grub).

I have a good backup system* so I wasn't too concerned (although this was my first real test).  I had run smartctl on the first sign of trouble and it didn't give any errors, so it didn't appear to be a hard disk failure. I figure this is an opportunity for me to setup 64bit version of Ubunt and I've also been thinking about dual booting to Windows® because Steam looks like an easy and cheap way to install games.

I put an old version of Windows XP in the drive and... it blue screened.  It just didn't want to install.  I tried two other versions and it also failed.  I then got the Ubuntu disk and it installed with no problems.  I tried Windows again, again it failed to install even though I had reformatted the disk …

Seven Segment Display in Inkscape

Today I got a little sidetracked while working on my key-train (keyboard training) project.  I thought I might spruce it up a little by using a seven segment display for the digits (say for the words per minutes), similar to what kTouch has.  I found an open source font, but it appears to be difficult to just use a ttf font in GTK.
So I figured, it's only 10 images, I'll just make them in svg.

I vaguely remembered a heathenx inkscape podcast describing how to make an LCD display and decided to use that at my base. Unfortunately, they didn't provide any source files in the show-notes (as far as I could see) so I had to watch and redo the drawings myself!

By naming each of the seven segments I could create the 10 digits simply by deleting a few elements in one template svg file.  I can create the template as beautiful as I like and quickly create the 10 derived images with theseprograms.

Unfortunately, both ImageMagick and GraphicsMagick don't handle svg blur properly so …
