"There’s a myth that if we were really good at programming, there would be no bugs to catch. If only..."

Sat, 29 Jan 2011 13:39:51 +0200

“There’s a myth that if we were really good at programming, there would be no bugs to catch. If only we could really concentrate, if only everyone used structured programming, top-down design… then there would be no bugs. So goes the myth. There are bugs, the myth says, because we are bad at what we do; and if we are bad at it, we should feel guilty about it. Therefore, testing and test case design is an admission of failure, which instills a goodly dose of guilt. And the tedium of testing is just punishment for our errors. Punishment for what? For being human? Guilt for what? For failing to achieve inhuman perfection? For not distinguishing between what another programmer thinks and what he says? For failing to be telepathic? For not solving human communications problems that have been kicked around… for forty centuries?”

Google tricks worth knowing

Google tricks worth knowing:

Some of that stuff is pretty well-known even outside the circles of the well-informed webizens, but it’s still worth saving because of it’s extensiveness and good formatting.

On the concept of searching for photos people took with their digital cameras using filenames as the basis, there is a webapp utilizing Bing for that: Random Personal Picture Finder.

A Ruby editor in Ruby

A Ruby editor in Ruby:

A promotional video about Redcar, a Ruby editor written in Ruby (using JRuby as it’s engine). Sure, it isn’t as good as the proprietary editors such as textmate or e, but still does the job and fulfills the paradigm that any language should have a specialized editor written in that same language.

DIY transhumanism

Mon, 03 Jan 2011 23:46:00 +0200

DIY transhumanism:

It’s a pretty interesting insight into what can be described as extending ordinary body modification (piercings, tattoos) and something less than “true” transhumanism (augmented reality eyes, prosthetic limbs stronger and better than natural ones). Of course as skeptics point out in the comments, this looks a bit like some post modern performance than true revolution in biomechatronics. To hell with them, new ideas can’t always come from the clean white-lit rooms of corporate R&D labs.

Essential Linux shell commands

Sat, 11 Dec 2010 18:40:25 +0200

Compiled from this thread on reddit.

Shift + PageUp lets you scroll up in console.

pstree - shows process list as a tree, useful for viewing dependencies between processes
reset - initializes terminal, good for cleaning it up after some nasty binary files
tmux or screen - for letting remote sessions stay up even in case of disconnects
htop - improved top, for better viewing of resource usage by processes
history - shows command line history
!! - last command again
!67 - command from line 67
!?asdf? - most recent command containing string ‘asdf’
Ctrl-D - EOF, terminates programs. Ctrl-C is interrupt, Ctrl-Z will stop the process (so you can either bring it back to foreground with fg or send it to background with bg)

There’s lots more good stuff in that same thread and also on http://www.commandlinefu.com/commands/browse

Future of processors

Sat, 04 Dec 2010 21:43:14 +0200

I have got a pretty strong feeling that most questions about the future of processor technology can be reduced to this:

For how long will the trend of Moore’s Law continue?

For the most optimistic guess one can just use the number from ‘Universal Limits on Computation’ by Krauss and Starkman, which puts it at 600 years. Of course that will require such breakthroughs in all disciplines related to computing that few of us can imagine today.

Looking at this question on a more down-to-earth kind of way, one might guess that it will continue to uphold for about 10 years, including the breakthroughs in technology. At least that is how it has worked so far and also because 10 years is such a short time frame when talking in an abstract way - of course we cannot say that when talking purely about technology!

Fixing broken refresh rate in Fedora 14 and KDE

Sat, 04 Dec 2010 21:40:43 +0200

So you’ve got a weird or old monitor and none of the desktop environments seem to fix it. After a few hours of hair-pulling and googling I managed to fix it.

As a preparation you need to know your monitor’s modeline. Under Windows you can use PowerStrip, but if you’ve only got Linux, check out this guide. There are other ways also of course.

First you need to generate /etc/X11/xorg.conf because F14 doesn’t come with one. Either do

# init 3

Because this one might not work, you might have to modify /etc/inittab

id:3:initdefault:

and then restart. Actually I suggest the second option, because Xorg seems to keep infinitely restarting in case of a faulty configuration, so you might be locked out of your system and then you have to use the rescue CD…

So after having restarted,

#X -configure

That will create a configuration file. As the command will say, test it. If nothing blows up, copy it to the appropriate location:

#cp /root/xorg.conf.new /etc/X11/xorg.conf

Now use your favorite text editor to modify that file and this is the relevant part what I ended up with (don’t touch the other stuff and of course substitute what I have with what you have!):

Section “Monitor”
        #DisplaySize      330   240     # mm
        Identifier   “Monitor0”
        VendorName   “GSM”
        ModelName    “”
        HorizSync    85.0
        VertRefresh 50.0 - 160.0
        Option      “DPMS”
        ModeLine “1152x864_85.0” 119.812 1152 1224 1352 1552 864 865 868 907 -HSync +VSync
        Option “PreferredMode” “1152x864_85.0”
EndSection

Try running X again, preferably using kdm or gdm. If it works, it’s all good. If it doesn’t, there’s 2 other things you have to do:

Modify /etc/kde/kdm/Xsetup and add these 3 lines

xrandr —newmode “1152x864_85.0” 119.812 1152 1224 1352 1552 864 865 868 907 -HSync +VSync
xrandr —addmode DVI-1 1152x864_85.0
xrandr —output DVI-1 —mode 1152x864_85.0

Add a new file into ~/.kde/Autostart I named mine resolution.sh and it’s contents are:

#!/bin/bash

xrandr —newmode “1152x864_85.0” 119.812 1152 1224 1352 1552 864 865 868 907 -HSync +VSync
xrandr —addmode DVI-1 1152x864_85.0
xrandr —output DVI-1 —mode 1152x864_85.0

When you are logged in, you can see from the terminal, that it indeed works:

$ xrandr
Screen 0: minimum 320 x 200, current 1152 x 864, maximum 8192 x 8192
DVI-0 disconnected (normal left inverted right x axis y axis)
DIN disconnected (normal left inverted right x axis y axis)
DVI-1 connected 1152x864+0+0 (normal left inverted right x axis y axis) 310mm x 230mm
   1280x1024      75.0 +   75.0
   1600x1200      65.0
   1152x864       75.0
   1024x768       85.0     75.1     75.0     70.1     60.0
   832x624        74.6
   800x600        85.1     72.2     75.0     60.3     56.2
   640x480        85.0     72.8     75.0     66.7     60.0
   720x400        87.8     70.1
   1152x864_85.0   85.1*

Now restart and your problems should be solved. During login the screen will change resolution 2 times, but at least you will get the resolution you want. Of course any better solution would be much appreciated. : )
