There are 3 types of lies: Lies, damned lies, and statisticsStatistics, infographics, data analysis and data science – who isn’t doing it right now. Everyone knows how to do it right, just left for someone to write how you SHOULDN’T do it. In the article we’ll try to fix it.

You are so lucky to be a programmer. I would like to be the programmer.
- Why do not you learn?
- I already tried. I checked out codeacademy and other websites, but it is not mine.
- Yep, the programming is not really for everyone.
- You are well paid, and you can create different things. Almost every day you get some crazy offers at least for 100 thousand dollars.
- Yep, honestly it's very flattering and a little mind-blowing.
- You get your share in the company and you know that the software engineers are always respected. You can implement any idea in the app and get rich. Moreover, you do not need to hire anyone for this.
- Actually, the programming makes me miserable.
- Wow. What do you mean by that?
- In order to be a good programmer, I need to develop a special mindset and that makes me sad. I noticed this in other programmers, of course, not all, but in many.
- What is this mindset?
- This is concentration on the strengths, and not on the weaknesses.
- Why do you need this to become a good coder?
- I work like this:
Do you remember this movie? What is it doing here? Why the hell such post on Kukuruku at all?
I guess, because I think that the main piece of IT is human, or rather our brain. I’ll tell you about another possibility of using your brain a bit more effectively. Everything described here has been tried out on me. It’s important to note that I’ll highlight if I haven’t tried something out. I didn’t use any drugs or devices. Popular methods have only been used. And yes, it’s devastatingly realistic. Having tried it once, you'll never resist telling about it.
GPGPU technology has stimulated the appearance of several renderings on the GPU in the market, including iRay, V-ray RT, Octane, and Arion. But open-source community made available at least two free renders on the GPU: SmallLuxGPU and Cycles Render. I want to share my impressions about the second one.
Cycles Render is unbiased render with the ability to render on the GPU (CUDA and OpenCL for ATI). It lies in a box with the Blender that runs on Windows, Linux, and OSX.
Cycles Render, this is a car with the procedural texture, FullHD was prepared in 2 minutes using GTX580.
Since the days of a Gold Rush a little has changed in the rating of high-risk enterprises by the man. A half century later, still in the same California is the Silicon Rush epicenter.
Here are in the photo San Francisco in XIX century and today.
These days it is almost impossible to find a clear and understandable description. Honestly, this is my first article (hopefully not the last one). I will give you an example of top 5 3D printed models.
The main part of the list is taken from the official blog post of Stratasys Ltd, (in the past it was Objet. Two companies merged into one), but this is not the point. The purpose of my post to show the capabilities of three-dimensional printing.
Presently, the distance learning system has been developing all the time. There is no longer a problem to get a good education remotely. Online learning has several advantages, such as learning at own pace, freedom and flexibility, accessibility, and social equality. The Web offers a variety of services to help gaining new knowledge.
MSL Curiosity did the most detailed geological research on Mars
Chemistry & Mineralogy X-Ray Diffraction is one of the most accurate methods of mineralogical analysis. Due to this method it is possible to find out the mineral composition, not the chemical. For example, diamond and graphite are identical in terms of chemistry, but the different formation conditions affected the crystal lattice structure and radically changed the mineral nature. The purpose of Curiosity was just to determine what conditions led to the mineral formation on Mars in the past.
Racing simulator experts know that the computer always uses the ideal trajectory, and it does not make any mistakes, but this is only in the game. What about the real life?
A couple years ago, I worked together with Ken Thompson on the interactive graphics language that was developed by Gerard Holzman in Bell Labs. I was typing quicker, therefore, I sat at the keypad, and Ken stood behind me. We worked quickly and when the compiler gave out an error, I started reflexively digging in a problem, studying the call stack, program output and launching a debugger, and so on. But Ken simply was standing nearby and thinking, ignoring me and a code, which we just wrote. Soon I noticed regularity that Ken often understood the problem faster than me and was saying, “I know, what is going on”. Usually, he was right. I understood that Ken built the mental model of a code, and when something was broken, it was the error in this model. He was thinking of how this problem could arise, so he explained what was wrong with model, or where our code could mirror this model incorrectly.
