vlisivka··on How a Mexican Drug Cartel Makes Its Billions
Food and water are even more addictive than nicotine.

Drugs are changing your brain by altering it rewarding system.

vlisivka··on How a Mexican Drug Cartel Makes Its Billions
So, if you will be legal drug seller and you will be tight on money, what you will do? Just invest into few small doses and you will have clients for life...
vlisivka··on How a Mexican Drug Cartel Makes Its Billions
What will happen to consumers when prices will be so low, so no body will want to sell drugs, because they are no longer profitable?
vlisivka··on How a Mexican Drug Cartel Makes Its Billions
Why you are worrying about revenues of cartels? If you think that selling drugs is legal, then their business is equally legal to business of Apple or Microsoft. Why you are not worrying about revenues of Microsoft or Apple?
vlisivka··on How a Mexican Drug Cartel Makes Its Billions
So if everything illegal will be legal, like in America before USA, then all gangs will gone?
vlisivka··on How a Mexican Drug Cartel Makes Its Billions
:-)
vlisivka··on How a Mexican Drug Cartel Makes Its Billions
Alcohol is already legal, so why gangs are not gone?
vlisivka··on How a Mexican Drug Cartel Makes Its Billions
Meth is very cheap already. Any changes?
vlisivka··on June 30th 2012 will be 1 second longer: 23:59:60
And if somebody will change time zone, then it will be total disaster for small tiny elevator controller: wall time will be shifted by hour!

SSL certs issued at :60 may have problem with validation. Just reissue them.

NTP can adjust clock by minutes. User can adjust clock by minutes, days, months, or even years.

EDIT: Simple time torture script is added:

  for((I=0; I<100; I++)); do date --utc --set=@$(( `date --utc +%s`+1 )) ; date --utc --set=@$(( `date --utc +%s`-1 )) ; done
vlisivka··on Zeolite retains heat indefinitely, absorbs 4x more heat than water
Can I use sodium acetate to heat my energy passive home (which I will build soon) by heating it at day in Trombe wall and discharging it at night?
vlisivka··on Anders Hejlsberg Is Right: You Cannot Maintain Large Programs In JavaScript
Definition of large program is "program, which is hard to maintain". So large programs are hard to maintain by definition.
vlisivka··on Why I Hate Test Driven Development
Did you ever saw how program crashes when run, but works fine in debugger (or vice versa)? What you will do in such case? What you will do after few such cases?
vlisivka··on Every Black Hole Contains a New Universe
Why you need 'other side'?

Our Universe has disproportion between (visible) matter and antimatter. Black holes my contain missed anti-matter. So when black hole will consume all matter of our Universe, it will bang again, without help of any parent Universe.

vlisivka··on Why I Hate Test Driven Development
So question is: why I awarded as "Top Performer", while I avoiding debugger at all cost? ;-)
vlisivka··on Why I Hate Test Driven Development
Why you need to look at them manually? Computer will compare all that much faster.

If you are good programmer and bug is non-trivial, you will create code to catch bug much faster than you will catch it manually. Moreover, you will be rewarded next time, because your code will be already written and ready to use.

vlisivka··on Why I Hate Test Driven Development
If you are programmer, why you debug your programs manually ?

I, personally, stopped to use debugger more than 10 years ago.

vlisivka··on Why I Hate Test Driven Development
Execute all these test cases by hands 10 times a day and feel the difference. You will enjoy automating after that.
vlisivka··on Functional programming in sh
You shouldn't write anything serious in shell or python, use serious language for serious jobs, please.

(But if you do, use bash-modules, please).

vlisivka··on Why do web sites and software take so long to build? And why is it so hard?
> But then, why would you rewrite from scratch?

Why not? Professionals knowns their tools much better, so they will made better choices in every aspect of project. If you place restrictions on their tools, they will work less efficient, unless you are already professional developer.

> The source (with doc) of a software is a compiled version of business/technical knowledge of the team that developed it and not really that good as a guide to the next team.

Of course. They will ask questions, so somebody from first team should respond to them.

vlisivka··on Why do web sites and software take so long to build? And why is it so hard?
Use Agile for R&D, user Waterfall for D only.

E.g. use Agile and smart guys with good knowledge of application domain for first version, then drop it and rewrite from scratch using Waterfall and outsource professionals.

vlisivka··on EU: Possession/distribution of hacking tools to be made a criminal offence
What about your brain, the best hacking tool?
vlisivka··on LENR device will be present today at NETS-2012
Nuclear and Emerging Technologies for Space 2012

Friday, March 23, 2012 ADVANCED CONCEPTS: LENR, ANTI-MATTER, AND NEW PHYSICS 3:30 p.m. Waterway Ballroom 2

3:50 p.m. Yang X. Miley G.

A Game-Changing Power Source Based on Low Energy Nuclear Reactions (LENRs) [#3051]

Excess heat generation from our gas-loading LENR power cell has been verified, confirming nuclear reactions provide output energy. Neglecting unlikely chemical reaction contributions, the energy gain is virtually unlimited due to negligible power input with gas loading.

vlisivka··on The one interview question I always ask
Mediocre is always good enough for employer. But mediocre employee will put additional burden on your top employees, so they will wear off quickly and jump off the board.
vlisivka··on Graphene supercapacitors are 20x as powerful, can be made with a DVD burner
So RepRap will be able to print it own circuit board? Astonishing.
vlisivka··on Tevatron confirms a 115-135 GeV Higgs
How you can confirm that there is no pauses in time? To confirm that, we need to watch something outside of our space-time continuum.
vlisivka··on A Classic Startup Horror Story
Army of lawyers may cost much more than NDA. :-)
vlisivka··on Advanced Bash Scripting
It is hard to write really large and complex programs in bash, so scripts stay small, which is good thing.

In my scripts, I declare and describe command line interface of each script, so it is not hard to rewrite script in an other language when necessary. About 5% of my shell scripts were rewritten in an other language (Perl, Java, C). I had no problem with that.

Other developers and admins are happy with my software, I even got some internal awards.

My documentation/code ratio is about 7/4 (7 lines of comments and documentation per 4 lines of code), so it is easy to catch design errors - they are hard to describe in documentation in most cases. :-)

I am avoiding debugger as much as I can (lack of builtin debugger in bash helps me a lot :-)), so my software handles errors in most cases and error messages are _very_ descriptive.

I have no problems with bash, perl, C, Java, JavaScript, etc.
