An interesting perspective on why Russia seems to have a higher representation of hackers as compared to the US:
https://krebsonsecurity.com/2017/06/why-so-many-top-hackers-hail-from-russia/

This article focuses primarily on how Russia has integrated computer science into school curriculums at much earlier grade levels than the US. On top of that, there are less opportunities (ie. Silicon Valley) in Russia for leveraging this education. It doesn't really delve into the "hacker" aspect, but shows that Russia has twice the amount of students taking AP Comp Sci exam as the US.

I think they've missed the mark a bit in only focusing on the education aspect, as many countries have great developers, but it's rare that you see them represented in the more malicious side of dev work.

Back in the early 2000's when I was focused heavily on affiliate marketing, I'd often see hacking of affiliate sites (for malicious cookie stuffing) and Adwords accounts (for rogue PPC ad groups) via Russian groups regularly and didn't understand why it was so prevalent.

After speaking with a friend who grew up there, I asked why he thought there was such a high volume of hackers coming out of Russia. His perspective was that "everyone steals, it's part of the culture and is one of the best ways to survive." One example that didn't click until he explained is how you see so many dash cam videos from Russia

I know I post a lot of article on here, but this is one you really should read.  Right now we are reaching the limits silicone.  The smallest transistors (that I have heard of) are just 7 nm (7 atoms wide).  At this point it becomes very difficult to make the transistor stable.  We are going to have to come up with a new material.  That's where quantum computing steps in.  It uses qubits , small particles that are smaller than an atom.  Unlike traditional computing, a qubit can exist as both a 1 and a 0 at the same time.  Again it is very hard to make them stable, but as we continue to increase them it will be the next big jump in computer technology.  And this one will make the jump from vacuum tubes to the transistor look like a pinprick!

I think you mean silicon, not silicone.

Hence informing the following:
Answer count depends on
1. data type you are using.
2. related programming language
3. compiler whether 32 bit or 64 bit
4. related applications(either a.out or program.exe or java or browser or ...)

Yesterday was Pi Day, and Experts Exchange held a little contest in honor of all things pi! Take a moment to read through the Pi-ku entries and leave your favorite in the comments.

As a mathematician, I have to go with Doug W's => he satisfied the requirements (# of syllables) with one word for each line, and did it with words relevant to pi :-)
