Updated version of elephants genealogy

2012-02-09T22:45:00.000-08:00

The release manager of Hadoop 0.22 and my namesake Konstantin pointed out that my diagram has alignment problems. So, I have posted a latest version to the same post. Enjoy.

I wish I can draw like Scott Adams

Because this is a complete Dilbert strip. Please, Mr. Scott - make the next one like this? :) I sweat - this is was the weirdest chat in my life (grammar and all that are original): Me: Good morning ;) A Person: no need to wink AP: I don't like it AP: not professional Me: Am I winking? Me: Interesting... Me: sorry for the non-professional offense AP: You emoitcons Me: ah… I don't have any

What you wanted to know about Hadoop, but were too afraid to ask: genealogy of elephants.

Hadoop is taking central stage in the discussions about processing of the large amount of unstructured data. With raising the popularity of the system I found that people are really puzzled with all the multiplicity of Hadoop versions; the small, yet annoying differences introduced by different vendors; the frustration when vendors are trying to lock up their customers using readily

Can SEI really teach you how to be Hadoop contributor?

2012-01-03T13:25:00.000-08:00

Or of anything else for that matter? I am kidding you not... I just got this email from SEI. In the interest of full disclosure - here it is: To the attention of: The Software Engineering Institute (SEI) has been asked to conduct a sample survey of committers to the Hadoop Distributed File System. The results will be used to supplement existing documentation that can be used in

New blog for Apache BigTop!

2011-12-27T16:57:00.000-08:00

We've just kicked off new blog for BigTop project - Apache Hadoop data stack creation and validation. Surprisingly, if got started with post on BigTop history Blog is available from ASF Blog roller at https://blogs.apache.org/bigtop/ - bookmark it!

Conception and validation of Hadoop BigData stack: putting the record straight.

2011-12-11T19:25:00.000-08:00

With more and more people jumping on bandwagon of big data it is very settling to see that Hadoop is gaining momentum by a day. Even most fascinating is too see how the idea of putting together a bunch of service components on top of Hadoop proper is getting more and more momentum. IT and software development professionals are getting better understanding about benefits that a flexible set of

Pointy-haired boss from Sun Microsystems...

2011-10-23T22:43:00.000-07:00

No kidding - there was a manager back at my last job at Sun Microsystems whom I had to explain 4 times a week why you can't "just add a link to that page" of the enterprise application and have it available in 15 minutes. I am kidding you not

Back in the day, in my alma mater, we used to have mandatory reserve officers training (one of the reasons why socialism sucks noodle). The lecturers were the dumb-ass officers who couldn't be kept any longer in the active military forces (among active military dumb-asses). At some point one of these imbeciles was blabbing about artillery calculations and in the course of "solving" an equation

Are former Sun executives cursed by a strong spell?

2011-07-25T23:23:00.000-07:00

I wonder if this is a curse of some kind that former Sun Microsystems execs are bringing viable companies down one after another? As many can remember great ponny-tailed pinhead applied some black magic to become Sun's CEO and then smacked it to the ground. Now it seems like we are seeing a similar patter in Yahoo! I wonder how Google survived through the times with their great defender and

I swear - I used to have that kind of manager... twice ;(

2011-07-22T22:00:00.000-07:00

I am sure most of you had the same kind from Dilber If you want to know what company you should never ever go to work for - leave me a comment: I promise to answer ;)

Spent at least an hour trying to mount an smb shared from my Debian server to 10.6.+ OSX laptop (I have no idea what kind of feline name it carries, nor I care enough for Apple to figure it out). As always the best answer comes from Ubuntu forums where a dude mentioned that certain tweaks need to be done to the samba server configuration. Namely, password encryption has to be enabled (even for '

OMG: my late (fortunately former) manager is in the news again!

Interesting analysis of iPhone pass code frequencies. Golly Gee, they are gullible, man! Besides, iPhone pass code protects nothing at all once iPhone is connected to a Linux system via USB cable ;)

Dilber nailed that again: I see dumb people (C)

2011-06-13T23:54:00.000-07:00

I am fascinated by Scott Adams: he expresses the story of my life very close to its sources... Very often (not all the time though). I have noticed that I am not a people person some odd years ago (despite various suggestions to read a book of Habits of Highly Crippy People Contrastively to the book, I like people in short bursts - 1-1.5 minutes long max. That's all because I have a very low

I'm sure everyone can recognize my late manager...

The fella is recreated in front of my mental eye with 100% accuracy! Oh yes, I am sure you had one like this in your professional life. You didn't? I am envious cause I already had two of those ;(

Thank you, Dilbert, for debunking open workspace crap!

Being an alumni of Sun Microsystems for more than 15 years I love isolated offices. I have one at home which is a sort of sacred place even for my dog. In fact, one of a biggest hardies of getting accustomed to Yahoo! environment were cubicles. Don't get me wrong - I like Yahoo! a lot: great company and mostly nice engineering culture! However, I hate cubicles with my guts - the noise level is

"Hadoop isn't without faults" said GigaOm

2011-04-26T15:59:00.000-07:00

I came across this GigaOm article which among some legitimate points (such as lack of innovations to hide the complexity of MR framework) also says that "Hadoop is the talk of the town when it comes to big data, but it’s not without faults...". Apparently folks @GigaOm have been looking into Hadoop very close to notice that Hadoop has faults. It has a lot of them. In fact, it has a special fault

Today I am going to tell you a true blood chilling horror story!American education sucks badly. US students and mostly indoctrinated morons without any real tangible knowledge. I have seen them making molecules models out of foam balls to pass a chemistry class (I guess it was 9th grade

As taken from this blogpost on Forbes"...Because there are only a limited number of potassium iodide tablets in the world, people hoarding them in the U.S. are preventing them from getting those who really need them—like the people in Japan. The Union of Concerned Scientists issued a statement saying that Americans should not stockpile the tablets..." (emphasis is mine)I am not discussing this

2010-11-28T19:21:00.000-08:00

A really interesting case of Freudian slip is in recent Bernanke's speech. The guy seems to understand that we are up to out throats in the steaming pile of economic recovery. Even more interesting is the fact that he seems to be using his brain often enough to admit that that steaming pile is only going to get deeper over time with all unfunded liabilities the Great Society endure us in the last

First derivative of US national debts (i.e. the speed of grow) is increasing

2010-03-14T12:53:00.000-07:00

Only a year ago I posted this little script to show a growth of US national debts in real time. According to this article the speed of growth was about $42K a second.As of today, the speed has increased to about $46K a second. Thus the acceleration is about $4K/sec over last year.Back in November 2009 US was at $12T of debts.At the moment of this writing (March 2010) the level of this nation

If you aren't sure how "money printing" works, or what is "reserve multiplier" is, and you have no stomac to read brilliant Murray Rothbard's "What Government Done to Our Money?" this video is for you.And Dr. Murthy is funny and brisk as usual :-) So watch it - you won't have any regret.

US national debt is outgrow $12T by 11/10/09

Basically, all people leaving in this country and being mugged by its tax collection, are indebted for an extra $44K each second. Doesn't sounds like much? Well...According to my calculations the national debt of US will outgrow $12T (yes, it is trillions!) by midnight of 11/10/2009 (Tuesday of coming week). Take a look for yourself - Debt ClockLet's celebrate, folks! It's going to be a true fest

I was watching this little video and came across the idea that it'd be much cooler to see how fast the debt is actually growing at each iteration (I can't subtract numbers in the proximity of 1014 every second or so just in my head).The crazy thing is that US government is piling up about $42,000 of fresh debt every second. It's like a size of annual gross income for many americans :-(Here I came

Hopefully, you'll like what you'll about to see.What reliability means for us.According to
