Legislative initiatives, especially in the United States, have often become the subject of irrepressible controversy and sincere misunderstanding. So today I want to tell you about bill 246 - a legal act that was considered in the Senate of Indiana in 1897.

imageThree years earlier, rural physician Edward Goodwin (1825-1902), who considered himself a good mathematician, published an article in the American Mathematical Months in which he claimed to have solved the problem of squaring the circle.

We do not intend to count here all the hardware and software problems that a computer can present, far from it. But we are going to tell you some of the most common ones.

Computer repair1. The PC is very slow. If your computer has decreased its performance, you may need to defragment the disk or you have installed a malicious executable that affects the speed of the system and you need a virus cleaning.

2. Operating system errors. If you see that Windows does not turn on correctly and indicates that there are errors or that your BIOS does not recognize the operating system, there may be important files that have been corrupted.

3. The computer does not turn on. Or it turns off. You may be talking about some kind of startup problem, but it's also possible that the power supply is failing.

4. Problems with the laptop screen. Sometimes the computer turns on, but if money casino games the screen is black. It may simply be that it was set to open on an external monitor, but the lighting may also have been broken.

The 7-Zip archiver does an excellent job of compressing data efficiently. It can be called a "Swiss knife" in the world of archivers. It supports various compression algorithms and a wide variety of data formats such as ZIP, gzip, tar and RAR. A separate plus is that the archiver is free.

The first version of 7-Zip was released on July 18, 1999; in a relatively short time, the archiver could become very popular. A relative disadvantage of 7-Zip is that there is only a version for Windows (official client). But now, after only 22 years, there is also a version for Linux, an official build from the developers.

As a rule, hackers try to lead a secretive lifestyle and maintain anonymity. Many succeed, but some of them are gaining popularity against their own will. This happened, for example, with Kevin Mitnick or Robert Morris. But there are other computer geniuses, about whose fate much less is known than about their exploits. One of these guys who left a noticeable mark in the history of world hacking was called Jonathan James. This is a man with a vivid but tragic life history that ended with an early and mysterious death.

imageA few days ago, researchers drilled the Antarctic shelf in order to take samples of sediments on the ocean floor. Instead, they found a colony of animals that couldn't be there. About their find tells Wired.

To study the history of the continental shelf, geologist James Smith and colleagues wanted to collect sediments on the seabed beneath Antarctica. To get there, they had to melt 20 tons of snow and create 20,000 liters of hot water. This water was pumped into a pipe lowered into a well. Which gradually melted the ice and sank lower and lower. It took them 20 hours to break through a kilometer of ice in this way.

imageimage After that, the geologists lowered a soil collection tool along with a GoPro camera into the borehole. But the manifold returned empty. They tried again. It's still empty. It was not possible to collect any soil.

This story began when I learned about existence bpytop ... I was amazed at the detail of the charts and I began to figure out how it was done. It turned out that Braille characters were used to display the graphs, which are a combination of 8 points: 2 points in width and 4 points in height. After looking for ready-made solutions using this approach, I found on reddit announcement such the project ... In the very first comment of the announcement, I read:
It's cool, but why don't people just rediscover ReGIS (vector graphics in the terminal) and sixel (pixel graphics in the terminal).
Until this moment, I did not know anything about sixel. Digging deeper, I found out that in theory sixel should be supported by xterm. I ran xterm on my ubuntu 20.04 in vt340 emulation mode

xterm -xrm "XTerm*decTerminalID: vt340" -xrm "XTerm*numColorRegisters: 256" executed the following command (convert is a command from the imagemagick package)

clear && convert <(curl -s https://upload.wikimedia.org/wikipedia/en/7/7d/Lenna_%28test_image%29.png) sixel:- and saw this:

Wow, it works!

You are at an altitude of ten kilometers, and you fall without a parachute. You have little chance, but a small number of people, finding themselves in a similar situation, managed to survive.
6:59:00, altitude 10,000 m

You went to bed early yesterday and you had an early flight today. You fall asleep shortly after takeoff. And suddenly you wake up abruptly - cold air whistles around you and a noise is heard. Terrible and loud. Where I am? - you think. Where is the plane?

You are at an altitude of 10 km. One. And you fall.

PM - Project manager (project manager).

You say that only 5 kettle will boil. PM insists that the client is asking very much and this is extremely important to us, you bend under the onslaught and decide to think about something. You throw a bag into the kettle, fill it with water and wait for the water to turn brown. You clearly understand that you will have to remember to wash the kettle, because this will leave tea rings and possibly mold. You pour the resulting colored water for the client, the PM says with a happy face: well, you see, you can. And you think that you would not want to do that to you ... But circumstances demand. And as soon as you relax, the PM flies in and says: have you even tried this?

You realize that there is no taste for the campaign ... You try to justify yourself, but then the PM interrupts you and says: what does the taste have to do with it, it's not boiling water and you quickly start thinking what to do. You think about boiling for a long time and find a ready-made solution - an old boiler in the closet. You throw it into a mug, plug it into an outlet, it heats up, and the PM looks at you and says: hmm ... We can't leave such dependence on the cable ... And you understand that a good solution just needs to be finished, naively believing that you are went in the right direction. You find the battery, connect it, and everything works, even though even the PM realizes that something is wrong here. And then the intrigue arrives ... PM-but there is no hour, two ... You start to think that they are either discussing your dismissal, or PM-and lost somewhere, maybe he has already decided to finish. But then the PM flies in and without a drop of explanation says: the client is very satisfied, it is necessary to make pasta just as quickly. You are at a loss - they say, okay, it worked, you go and look at the kettle and think, what else can be done in it. But since it's Friday night, you think that you've had enough of such adventures and agree with the PM for Monday.

When humans settled in Central America (about 15,000 years ago), they didn't have to domesticate the avocado. Pick these wonderful fruits from the tree and eat. Save the bones and plant wherever you want. No fiddling around raising fruitful varieties from wild ancestors. These are not millennia-long attempts to domesticate corn.

But how did it turn out so well? The fact is that all the breeding work, even before people, was done by someone else, simple, but big. And people came to everything ready.

imageTo understand how this happened, let's observe how natural selection works in plants. To win the competition, they have to come up with clever breeding methods. The task is to spread the seeds over a large area.

If your seeds just fell and rotted under the tree, there is little use. Part of it will certainly germinate, an even smaller part will survive to adulthood. But the population of such trees is at great risk, because the parent is competing with its own children in a small area. You need to spread in all directions and occupy free spaces, then the species will flourish.

Google said that community, bringing people together is at the core of their corporate culture and office spirit, so they are investing $ 7 billion in an existing office, as well as opening offices in Minnesota, Texas (the highest priority point for technological growth in recent years) and North Carolina. Also Google plans to double office expenses. This decision seems significant and even somewhat surprising against the backdrop of the triumphant march of the distance, which the companies became closely acquainted with in the "covid" 2020.

imageIn a pandemic year, Google, like everyone else, slowed down recruitment, but now is the time to pick up steam. The company said it will add thousands of new employees at existing sites in Atlanta, Washington, DC, Chicago and New York, expanding the company's multi-year expansion beyond Silicon Valley. According to Alphabet, there were over 135,000 Google employees worldwide as of last year.
