Introduction


Hello my dear umumbleuser! In this post I am going to discuss the sleep and productive activity. I am interested in the topic of my own productive sleep. The last few years I thought that the sleep is just a waste of time, and therefore, I tried to shorten the time of my sleep. But the more I did it, the more I began to look like a zombie, and then I began to look for an alternative. Consequently, this post will be a synthesis of all the information I found. Let us begin!

We learn during our sleep

I would like to begin that sleep is not a waste of time. It was a great discovery for me. Our brain does not rest during our sleep, it processes the information. All the time while we are peacefully sleeping and dreaming, the brain is processing all the received information for the day. What it finds useful it puts in long-term memory for years to come, but that is not needed it throws out. Thus, when we are awake, we only collect information for further processing in our sleep. So, how does this happen? Here we need to get acquainted with concepts such as the types of sleep.

Copy-Paste, Ctrl-C, Ctrl-V
I create the PVS-Studio analyzer detecting errors in source code of C/C++/C++11 software. So I have to review a large amount of source code of various applications where we detected suspicious code fragments with the help of PVS-Studio. I have collected a lot of examples demonstrating that an error occurred because of copying and modifying a code fragment. Of course, it has been known for a long time that using Copy-Paste in programming is a bad thing. But let's try to investigate this problem closely instead of limiting ourselves to just saying "do not copy the code".

Recently I came across a video on Youtube, which shows technology of the Smart Window.

The Smart Window casts a touch-controlled interface onto transparent glass with ambient light. Samsung was demonstrating a whole range of applications from Twitter to Microsoft Office, all touch-controlled and viewable directly on the glass. Images are viewable in daylight, and there's a nighttime mode that uses side-lighting and flipped colors. It could be found in hundreds of movies and TV series, starting from the Star Trek.

It seems that you only have to solve the problem of voice recognition, and the touch screen will be exactly the same as in the Star Trek.


Can you imagine putting one of these in every room of your house?

"C++11 feels like a new language." - Bjarne Stroustrup

Recently, Herb Sutter has opened on its website a new page “Elements of Modern C++ Style”, where he describes the advantages of the new standard and how they will affect the code.

C++11 standard introduces many new features. Next, we focus specifically and only on those features that make C++11 really feel like a new language compared to C++98, namely:

• They change the styles and idioms you will use when writing C++ code, often including the way you will design C++ libraries. For example, you will see more smart pointer parameters and return values, and functions that return big objects by value.
• They will be used so pervasively that you will probably see them in most code examples. For example, virtually every five-line modern C++ code example will say “auto” somewhere.

Who remembers the game called WipeOut, those will please Japanese movie from Japan Advanced Institute of Science and Technology(JAIST). They have made a model of WipeOut track in reality


Levitation is based on the Meissner Effect. Bolides are cooled with help of liquid nitrogen.
Сonsiderable interest arousing the bolides controlling system, but unfortunately we don't have any additional information

The design management is a very interesting thing, it seems as if it is, but on the other hand, it is not. At the same time, there exists an unstable verge between reality and fiction, and many people make good money on that, including me.

Honestly, this text writing pursued the selfish goals: it is some touchstone to be sent to people with which we will have to collaborate.

After we dot the i's and cross the t's, we have to either rush headlong into the abyss of passion, or delimit our areas of activity completely. So, let us talk about the screwups and why they cannot be fixed.

Introduction


I have a Toyota Corolla 2003 with the factory built-in a car cassette radio. Of course, I have never used the cassettes, but a radio and fm modulator came in handy for me.
I am not particularly a music lover, but I wanted something more. Here are options what I had:
1. Put the frame for 1 or 2 din and install the ordinary cassette radio.
2. Buy its native one for $ 70 dollars on eBay with the CDs, but without the MP3 :)
3. Buy a fancy one for $ 600 dollars that would fit to my car.

However, I did not like any of the above…
1. An ordinary cassette radio did not have any computer.
2. Trade bad for worse :).
3. It is too expensive and not very popular ...

There came an idea to install the computer in the car. Here is what it was before and after.

I have always been interested in a subject of electric transport. When I finally moved from theory to practice, the long-awaited moment came. I would like to share my experience below.

Here are a couple of thoughts as an introduction.
Why now is everybody talking about electric cars, electric airplanes and electric bikes so actively? Finally, the main problem of electric transport was almost resolved, because there began appearing the quite compact and high-capacity batteries. Moreover, they are being charged for the acceptable time. In fact, just this was waited, and all the rest as a car body, chassis, electronics and electric motors were created a long time ago. All of this has already being used for a hundred years. The electric motors allow using the new solutions; for example, to be installed in the hubs of wheels.

Let us get to the point!

Technical characteristics:

- ordinary bike, the price is about $ 200
- electric motor: 48V / 380W
- battery: 48V / 10A
- speed without pedaling on a flat road 35-40 km / h
- traveling distance: 22-25 km on the hilly country and the city
- total charging time: 2 hours
