Factors that will drive Python growth in 2018

Python was the fastest growing programming language in 2017. Although Python has been around quite a while, the recent growth factors many aspects. One of the major aspects is the rise of data science, data mining and machine learning.

Hi, I’m sure many of you are probably sick of answering this question, so apologies in advance.

I’ve been following (not trading) BitCoin for the last year. A few friends etc have invested in it, etc.

I have a few questions:

01 - I know this is hard to call, but I’m sure I’m too late to the BitCoin game, BUT are all crypto currencies the same in this regard or are some only worth very small now but could potentially explode like BitCoin?

02 - How do different things influence different crypto currencies, or are they all influenced by the same thing?

One of my favorite things to do is play games. Seriously, I built an entire table from scratch for nothing other then to play and store my many games.

I also know new parents and veteran parents who are looking for more fun to have with their young children.

So when Google Announced that the Assistant, Home and Mini would be able to play games…I had to investigate.

Google breaks it down into these categories:

Learn Together
Have fun with your family and little ones with quizzes or learn things together.

CK-12 EDU Trivia (Hey Google, talk to CK-12)

Subject of the week | Tell us about a technology you'd like to learn.
I'm fascinated by developments in Machine Learning and want to, heh, learn more about it. Not so much because I want to create Machine Learning systems myself—I have very little interest in the math involved—but so I can know how to leverage the sort of things that are being built. I easily envision the future of most work being about managing various bots and knowing how to apply them to higher level problem solving.

To get started on that path, I'm currently teaching myself Python (via several books on the subject) and would then transition into the use of it to dig deeper into the Machine Learning libraries. (And if I have to, even some refresher on the math... I did pass the AP calculus test, but that was 20 years ago!)

Any of you out there with more knowledge in these areas have some advice on this?

Not sure about "huge", but at least plausible. Lots of research needed for use by football players, since they won't quite match species evolved for constant usage like that. Veins/capillaries might not have quite the appropriate wall strength for regular stress, and other related issues might arise. Long term effects might approach those of high blood pressure.

It maybe could be much more interesting if we could learn effects at much younger ages. But it's not so easy studying younger than informed consent ages.

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

Become a CompTIA Certified Healthcare IT Tech

This course will help prep you to earn the CompTIA Healthcare IT Technician certification showing that you have the knowledge and skills needed to succeed in installing, managing, and troubleshooting IT systems in medical and clinical settings.

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!

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 ...)
