LaTeX is cool and easy

Well, last week I was working on a document that needed to be neatly formatted and I didn’t want to go with the usual chores with WISIVIG environment. Yes, I am a big fan of OpenOffice, but these guys have some drawbacks when it gets to the accurate representation of your work once printed.

Anyway, I decided to give LaTeX a try. I’ve been avoiding this thing since my time in the grad school: I thought it is crazy. a mess and hard to learn. Well, either I got much smarter in the last 20 years or Mr. Knuth is an incredibly clever person, or likely the both 😉

It took me about twenty minutes to get everything installed and running (thank you Ubuntu for packaging up TexMaker!) and the draft version of my paper neatly formatted. Well, I have spent another two hours polishing it to where I finally liked it, but this is beyond the point – I have high standards 🙂

Did I fell in love with Tex? No, I don’t think so, but it turned out that programming your papers is fun and let you have a professional looking documents with ease.


HortonWorks distribution: secretly powered by iTest and BigTop?

As I’ve mentioned here, and here BigTop is a real neat concept that I and a couple of my friends have put together a couple of years ago. Interestingly enough, second incarnation of the concept (known as iTest) made (back then) my manager to accusing me of stealing software in favor of ASF, followed by forceful departure from Cloudera (kick in the ass, with ‘I am sorry’ kinda smile on their face). But this all this in the past. The present however is much more interesting…

Some evidences were found that BigTop project (see first two links above) is seen as a power behind commercial offerings of some of the leading Hadoop vendors. Here how interesting it gets:

  • you can get HortonWorks’ stack AMI from this link to play with and learn about Hadoop and stuff.
  • now let’s see what they are using to power-up their distro

$ grep -i     –extra-dir=DIR    path to Bigtop distribution files     –build-dir=DIR    path to Bigtop distribution files [ -e /usr/libexec/bigtop-detect-javahome ]; then  . /usr/libexec/bigtop-detect-javahome [ -e /usr/lib/bigtop-utils/bigtop-detect-javahome ]; then  . /usr/lib/bigtop-utils/bigtop-detect-javahome
oozie.init:if [ -e /usr/libexec/bigtop-detect-javahome ]; then
oozie.init:  . /usr/libexec/bigtop-detect-javahome
oozie.init:elif [ -e /usr/lib/bigtop-utils/bigtop-detect-javahome ]; then
oozie.init:  . /usr/lib/bigtop-utils/bigtop-detect-javahome
oozie.spec:#Requires: bigtop-utils

now if you look a bit further, there some more hints that BigTop has been used big time, but that hasn’t been hidden away very well…

oozie.init:if [ -e /usr/libexec/bigtop-detect-javahome ]; then
oozie.spec:#Requires: bigtop-utils

Wow, I feel proud, guys, I really am. Now I can officially claim that my ideas are giving the push to some of the biggest vendors of what is considered the hottest technology on the market 😉 Although, they are unlikely to admit this publicly, predicating on the above example.

I will keep you posted on the development.
