Finally upgrading from Debian Lenny

If you like me was putting of an upgrade from Debian 5.0 Lenny you might find yourself blocked out, because ftp.us.debian.org/debian/dists/lenny doesn't exist anymore anywhere on the US mirrors. However, I needed to do one last update before getting on dist-upgrade. 

Luckily enough I was able to find a mirror in Germany which still has Lenny dist around. So, if you find yourself in my shoes edit /etc/apt/sources.list on your system and replace 
 ftp://ftp.us.debian.org/debian/
with
 ftp://ftp.de.debian.org/debian-archive/debian/

then do usual update and then an upgrade. Good luck!

Mark Twain and data science

When I look at data science nowadays it reminds of
In the space of one hundred and seventy-six years the Mississippi has
shortened itself two hundred and forty-two miles.  Therefore ... in the Old
Silurian Period the Mississippi River was upward of one million three hundred thousand miles long ... seven hundred and forty-two years from now the Mississippi will be only a mile and three-quarters long.  ... There is something fascinating about science.  One gets such wholesome returns of conjecture out of such a trifling investment of fact.
                 Mark Twain
I don't know why...

Hadoop genealogy simplified

I have decided to simplify the elephant genealogy tree by separating pre-Hadoop 2.x part out of it. The new supported version will only be reflecting Hadoop 2.x. The last updated full version of the diagram is available for anyone from my github workspace under the tag WDD4

Smart-ass recruiters out there....

An spam-email from a recruiter (target company name isn't mentioned _anywhere_):

   I came across your resume on Dice and would like to talk to you about
   a Hadoop Engineer position with our client, which is a Fortune
   10 company based in Cupertino, CA. This is the largest and most
   valuable consumer electronics/technology company in the world today
   which makes cutting edge smart phones, personal computers & music
   players. 


Now I wonder which one of us is an idiot?

Git is absolutely fabilous, of course

After using git for like 5 years - and shall I say I know most of the tricks in the book and outside of the book ;) - I still find some neat things in it, that please me immensely in spite of being simple.

I am doing this Gradle implementation of Apache Bigtop build system and thought that would be about time to split one Gradle file in two: separation of concerns and all that stuff. So, naturally I have fired-up IntelliJ IDEA, did some splitting, and copying, and other things. Got all my functionality working to the same extend as it were. And now it is time to commit: I have original build.gradle and new packages.gradle files. So,

% git commit -a -m 'Separating build logic into its own module'

[BIGTOP-1201 f319b55] Separating build logic into its own module
2 files changed, 53 insertions(+), 429 deletions(-)
rewrite build.gradle (90%)
rename build.gradle => packages.gradle (90%)

Seriously, how smart and cool is that?

ASUS t700 keyboard layout switching with dock

If you - like myself - are dealing with more than a single keyboard layout (e.g. Russian and English) you might have experienced the pain of using on-screen keyboard even if the dock is attached. Look no more - here's the easy 2 steps solution for your troubles.

I think it really doesn't matter if you're using Android keyboard or Hacker's keyboard (like I do), as this functionality seems to be coming from dock keyboard driver.Now...
Open up Settings -> Language & Input


Under Physical Keyboard select "asusdec" and configure it to your liking.

To switch between layouts just hit Ctrl-Space and you're all set. Enjoy!
