Some places do ask “puzzle questions” - but they aren’t generally for testing IQ, they are intended to allow the interviewers to see how the candidate approaches a problem. We don’t say: “Here is a problem, figure out the answer” - we say “Here is a problem, we don’t care whether you get it right or not - but just tell us how you’re trying to solve it.”
There are many examples - we used:
You’re playing ‘Russian roulette’ where you have a loaded revolver, and take turns with another person putting it to your head and pulling the trigger. This time, there are two bullets, placed in consecutive chambers of a 6 shot revolver. The other person spins the cylinder, puts it to their head and pulls the trigger…CLICK!…nothing happens. They hand the gun to you - you have the choice to either spin the cylinder again or to leave it as-is before putting the gun to your own head and pulling the trigger. Which is the safest thing to do?
If you just tell us the answer - that’s not what we wanted - so we’ll just grab another question and give you that instead.
We want you to be doodling on the white board - or doing statistics with math - or…whatever it is you do to figure it out.
Worst thing you can do is to guess…”It doesn’t matter”…is a typical guess and that would be a black-mark on the interview form!
I like reactions like “Well, if I spin again, I have no information about the outcome - but if I don’t spin again, then I must know something I didn’t know before the last guy pulled the trigger”…which is good. Then we can ask “So…what use is that information?”…and so forth.
Work Injury Attorney
Workers comp laws give an approach to injured representatives to verify advantages following a mishap at the work environment. By recording a case with the protection firm of the employer's, casualties of working environment mishaps begin the way toward recouping repayment for lost wages, medicinal costs, and handicap installments. The establishment of a fruitful workers comp guarantee is the restorative documentation and proof that the activity caused damage.
The California workers pay framework gives focal points to specialists who've been harmed in a mishap that happens out of and over the span of work regardless of deficiency. At the point when a sufferer is harmed at work in a gear mishap, they're qualified for these advantages. For example, if a specialist is in charge of illuminating apparatus issues yet neglected to do as such, they wouldn't be banished from recuperating benefits on the off chance that they endured wounds over the span of their work.
The Linux Certified Engineers ensures the network of an organization is up to date and is secured on the Linux platform. IT professionals participate considerable time learning about server computing for everything from installation, configuration, maintenance and virtualization to application support, among other things.
Various IT professionals are working with and nearby Linux operating systems regularly, along with Windows and different UNIX OS brands as well.
Linux Certified engineers should monitor, tune, and update operating systems to provide the required functionality and security. Linux Engineers install new software releases, system upgrades, evaluates and installs patches and resolves software related problems. Engineers maintain data files and monitors system configuration to ensure data integrity.
Firebird, MySQL, and PostgreSQL are probably the most famous representatives of DBMS. Naturally, these projects often are compared with each other - by functionality, usability, etc. We have decided to perform our own code quality comparison of these projects.
The article gives a review of bugs, detected using PVS-Studio static code analyzer. A 'direct' approach of comparing by the number of warnings in this case is badly applicable, so you have to find other ways to compare. For example, you can analyze projects for potential vulnerabilities, as well as to see which of the most interesting errors will be found. By undertaking such a review, you can estimate, which code is better, and find out who will emerge victorious from this battle.

Honestly I warn: take this text with a certain amount of skepticism. I just recently started to get acquainted with the internals of PHP, but I would like to tell you about what is happening behind the scenes bug # 75237 .
Is the rabbit hole deep?
How many minutes do you need to understand what the chip is?
Francis Bacon in 1620 divided the sources of human error in the way of cognition into four groups, which he called "ghosts" or "idols" (Latin idola).
"Ghosts of the genus" stem from human nature itself, they do not depend on either culture or individuality of a person. "The human mind is like an uneven mirror, which, mixing the nature of things, reflects things in a distorted and disfigured form."
The inspiration for writing this article was obtained after reading a similar publication for the x86 architecture .
This material will help those who want to understand how the programs are built from the inside, what happens before entering the main and why all this is done. Also I'll show you how to use some of the features of the glibc library. And in the end, as in the original article , the traversed path will be visually represented. Most of the article is a parsing of the glibc library.
So, let's start our trip. We will use Linux x86-64, and as a debugging tool - lldb. Also sometimes we will disassemble the program with objdump.
The source text is normal Hello, world (hello.cpp):
std::cout << "Hello, world!" << std::endl;
Something is happening. People are unhappy. The specter of civil unrest is pursued by our programming communities.
For the first time a significant number of web developers openly question the web platform. Here is a typical article and discussion of . I could list more, but if you are sufficiently interested in programming to read this article, you probably already read this year at least one pompous recitation about the current state of web development. This article is not one of those. I can not compete in bullying the existing status quo with people who have to deal with web development every day. This is another article.
It's you, the front end hacker
Slightly less than the fastest, portable, 64-bit hash function, with decent quality.
Yes, in the air and in the king, about like that. Read on?
Instead of Disclaimer We drop the definition of hash functions along with a detailed listing of properties and requirements for their cryptographic application, assuming that the reader either owns the necessary knowledge minimums, or will make up for them . Also we agree that here and further we mean non-cryptographic (cryptographically non-persistent) hash functions, unless otherwise specified.
In fact, it's been two days already, but no one has yet written an article on Habr, so I will have to eliminate this omission, which I do with pleasure.
So, what's new in this version of PostgreSQL?
First, the versioning itself has changed. Prior to the "dozens", we observed a lot of minor versions of 9.x that came out about once a year and at the same time introduced serious, far from minor changes. Therefore, since version 10, it has been decided to number 10, 11, 12, etc. By the way, MySQL seems to have gone the same way, jumped from 5.7 to 8.0
Okay, it's all trivia, let's move on to the essence of the question
