Chuck Norris in Ruby
intinig ported Chuck’s roundhouse kick power to ruby! Have a look..
http://github.com/intinig/chuck_norris/tree/master/chuck_norris.rb
It’s a proof-of-concept, of course :).
I've already got Mac OS Snow Leopard 10.6
And this is the proof:
( Of course, if you know about SystemVersion.plist, skip this entry ;) )
What does your .bash_history say?
A friend of mine told me that on techie blogs there is a new meme going on: show off the most used commands, starting from shell history:
history | \
awk '{a[$2]++}END{for(i in a){print a[i] " " i}}' | \
sort -rn| head -15
I’ve got 20 times the default bash history size (10k lines), so it’ll yield interesting results. I also use the history timestamp feature, so I’ve added a little sed to the code in order to strip timestamps out.
Let’s see:
13:19:50 vjt@voyager:~/code*$* history |
sed 's#^[ 0-9\[\/\:]*\]\([^ ]*\).*#\1#' |
awk '{a[$1]++}END{for(i in a){print a[i] " " i}}' |
sort -rn | head -15

yeah, I do a LOT of ls, l is actually ls -alFGs (I’m on Darwin). This list exposes my recent habits, because I’m coding less and managing more (no gcc, no irb, lots of dig & whois). svn is still there, of course ;). ssh means that these results should be aggregated with other histories coming from the other boxes I log on to.. but that’s a topic for anoter post ;).
Which are your results?
Post them here! :D
UPDATE 2008-06-03
As my recent habits are more coding than writing docs, I re-ran the history analysis.. and these are the new results:

We still can do it
Well, it seems that I’ve got no reason to be paranoid about my age: I still can do inline like I did (everyday) when I was a bit younger :).
On international workers day, 1st of may, sam literally carried my out from home, far from the computer, and we went skating. It’s been an awesome day, we skated a lot, and shot some nice photos.
But the real good ones have been shot when ndstr caught us. He is by far the best photographer you could met, and of course my favourite one (take a look at his site!).
He’s been also a skater, so he knows very very well how and when to shot in order to take out the most from your tricks :). Here are two of them, portraying me and sam while doing our best!
It was fun. Really fun. Thank you sam for taking me out of home :D.
Oh, and don’t forget to visit my deviantart, and look at this one :D
10.5.2 Odissey: a small journey in Mac OS X services and components
Well, I’m really happy with OSX 10.5.2. Even I’m not the one that blamed Apple for the translucent menu bar that everyone dislikes.. well, I like it. I don’t care about the TM menu bar tool, because I haven’t bought (yet) the nifty Time Capsule, I like the spinner in the Airport menu and, most of all, I really like the updates to the BluetoothSCOAudioDriver.kext that drives my bluetooth headset.
Spotlight also feels faster and faster on every upgrade, and I’m a heavy spotlight user, so this makes me really happy. Thanks Apple engineers!
Back to the topic: why odissey? Because as per my battery hints, I managed to make my MacBook2,1 SHUT DOWN while at 74% of the “Writing files” phase of the combo update… resulting in a completely broken system, as every geek could imagine :). Apple updated some libraries, and upon reboot simply nothing worked, and the darwin console was filled with lots of error messages.
Google Maps (part I of "The Googling")
Ever had some concerns about Google Maps and how much that app can see about your house, your car, yout neighbours and … maybe … yourself?!? Well, maybe you are right! Have a look at this video from the vacationeers ...
;D
how to keep your apple notebook battery healthy
3 simple rules:
- DO NOT leave your charger connected when the battery is charged, even when you go to sleep.
- DO let it discharge completely, when using it wait till it reaches 0%, when sleeping it leave it alone, when you’ll wake up and you’ll open it, a resume from suspend to disk will greet you. OSX FTW.
- Monitor it and show off OSX performance counters to your friends (images courtesy of CoconutBattery.app and System Profiler.app)
Ruby 1.9 has got the answer to life, universe and everything
22:33:24 vjt@voyager:~$ irb19 -f
irb(main):001:0> Symbol.all_symbols.grep /^the/
=> [:the_answer_to_life_the_universe_and_everything]
! :)
unluckily, the answer isn’t 42:
irb(main):002:0> _.first.object_id
=> 5048
:\
Thanks for this strange finding, nextie! :D
When Sysadmins Ruled the Earth
A really really really NERD novel by Cory Doctorow that tells about a bunch of sysadmins that strive to keep the good ol’ Net online, after a catastrophic event that brought the entire world to its knees. They fight with scarce power and food supplies, and communicate over the Usenet… using the “good old alt. hierarchy”.
Vote: 10+ for the geekiest thing I’ve ever read, it’s really worth the hour needed to read it completely. Enjoy it.
How to backup with time machine on a network share
Ingredients: Debian, Netatalk, Avahi, some trickery.
Step 1: recompile netatalk adding SSL Support: blackmac.de.
You can safely ignore the ”.passwd” stuff, because afpd uses PAM for user authentication.
Hint: disable the atalk protocol handlers in /etc/default/netatalk, for a faster startup:
