Culture feedback: how not to slip to charges

3r3355. Quality feedback on time signals how true we are moving towards the goal, whether we need to correct the course or change the speed. Or in general, urgently move in the opposite direction and change the mode of transport. Kontur University has recorded a video about major OS errors, how to avoid them and not spoil relations with colleagues.
 3r3365. 3r3355. The rules, which will be discussed, work in all spheres of our life. When properly applied, they will help to provide an effective and mutually useful feedback.

Checking the LibrePCB project using PVS-Studio inside the Docker container

Checking the LibrePCB project using PVS-Studio inside the Docker container 3r38080. 3r3669.  
This is a classic article about how our team checked the open LibrePCB project with the help of the PVS-Studio static code analyzer. However, the article is interesting because the check was carried out inside the Docker container. If you are using containers, we hope that the article will demonstrate another simple way to integrate the analyzer into the development process. 3r3669.

How Clang Compiles a Function

 3r3308. 3r3-31. I planned to write an article about how LLVM optimizes a function, but first you need to write how Clang translates C or C ++ to LLVM.

if (a> a[i + 1])

} 3rr989.  3r3308. Since Clang does not make any optimizations, and since LLVM IR was originally designed to work with C and C ++, the conversion is relatively easy. I will use Clang ??? (or a close version, since this one has not yet been released) on x86-64.

The secret of the ritual “warming up” or why “warm” headphones sound “better”

 3r3144. 3r3-31. A couple of years ago we already touched so-called themes warming up the headphones . Then we found out that the manufacturers of headphones are consider "warming up" heresy do not have specifications about the "warm-up" and declare that it does not change anything. In particular, representatives of Shure and Sennheiser noted that Their products are ready for use without additional rituals 3r33333. does not need prior preparation or adjustment for accurate sound reproduction.

Headphone Review Sony SBH90C: Wireless or USB Type-C?

Headphone Review Sony SBH90C: Wireless or USB Type-C? 3r3365.  
3r3365.  
The widespread abandonment of the 3.5 mm headphone jack broke smartphone users into two camps: some were unhappy that they would have to make compromises in terms of sound quality and charge another device, others enthusiastically accepted this change, appreciating the more monolithic design of the devices and the convenience of the wireless connect. The most advanced even fantasize about the possible rejection of wired charging, but this still seems to be a too radical change in user experience. A compromise between the two opposing sides was found in the Sony SBH90C headphone model ...

Two bits per transistor: Intel 8087

Two bits per transistor: Intel 8087high-density ROM on a floating point chip.Intel developed the 8087 chip in 1980 in order to improve PC performance with 8086/8088 processor lines (such as the IBM PC) when performing floating point operations. Since the first microprocessors were designed to perform operations with integers, the execution of operations with floating-point numbers was slow, which already speak of performing transcendental operations, such as trigonometric functions or logarithms. The 8087 coprocessor significantly increased the speed of performing tasks with a floating point, everything was performed almost 100 times faster. The 8087 architecture was also ...

FCC: SpaceX satellites in orbit - a source of debris dangerous to Earth’s inhabitants

FCC: SpaceX satellites in orbit - a source of debris dangerous to Earth’s inhabitants  
 
According to the analysis of the figures given by the FCC regarding the lifetime of SpaceX satellites (Starlink system) in Earth orbit, the probability of hitting someone on Earth with a satellite fragment will reach 45% every six years. It sounds a little difficult, literally it means that the fragments of satellites will fall to Earth every day, sometimes reach the surface of the planet, and sometimes kill someone from the people.
