We Have a definitely good news: the search giant Google apparently has changed its strategy regarding competitor DuckDuckGo. The company has included "duck" in the list of search engines by default, Chrome for 60 different regions. The update comes with version 73 Chromium. In this case, the engineers at Google claim that no "trick" in their actions there — they just updated the lists according to previously collected data about the user's preferences. therefore, the company recognizes that the popularity of DuckDuckGo grew up and became noticeable to make such adjustments. The list of countries that have received DuckDuckGo out of the box are very diverse: from Costa Rico and Honduras, to Canada, UK and even India. By the way, for the Russian Federation...

Introduction matrix Multiplication is one of the basic algorithms, which are widely used in various numerical methods, and in particular machine learning algorithms. Many implementations of the forward and backward signal propagation in convolutional layers pronnoi network based on this operation. Sometimes up to 90-95% of the total time spent on machine learning, it is necessary on this operation. Why is this happening? The answer lies in a very efficient implementation of this algorithm for processors, graphics accelerators (and in recent years, and special accelerators matrix multiplication). Matrix multiplication is one of the few algorithms that allows you to effectively utilize all computational resources of modern processors and graphics cards. It is...

You Know, when I almost accidentally found out by reading the excellent book by Dmitry Ketov "inside Linux" (and not advertising) that each of us downloaded the file from the Internet with a light hand of the browser leaves in extended attributes of the file (in the inode of the file, not the file itself) as a minimum, the full url where it was downloaded, I came to a slight excitement and wanted to immediately rush to save the world. Later, a little after studying this issue, reading "commits" and "comments" saying that this feature, built into the GNU/Linux kernel, at least for about 10 years that it is not only browsers, but also, for example, the popular utility wget (curl is not), and that this thing is almost the norm in Linux (and as it turned out...

If, on the report of Artem Malyshev (proofit404) will make a film that will be directed by Quentin Tarantino movie Django he has already made, will be removed, and the second.

Hi, Habr! This article inspired me to write a wonderful story of how one new Zealand company, 8 weeks, worked with three days off. And how we use them as if proud. Context the Last time I care about here is what topic: from turquoise as a great team not to become chelovekami Corporation. Still concerned about toxic teams, burnout and the pursuit of happiness. In labor. We figure out how to control it and that the first trials and experiments, of course, put on yourself. It is obvious: we are engaged in HR in it. so Experiment: four day work week. the Place: Moscow and Kiev. A distributed team. Intellectual labor. Self-sustaining commercial company. the duration of the experiment: over 100 employees/years. more under the cut. Read more →

Introduction since his youth, when we had an old DeskJet, I was interested in the cartridges of inkjet printers. These cartridges seemed very interesting and as soon as they were out of ink, I immediately took them myself. At the time I couldn't do anything with them, but to disassemble and to get your hands dirty... even Though I knew that inside there's some complicated electronics, but when you touch the battery contacts nothing interesting has happened, but my knowledge on electronics no longer enough. a Little later, when I became a student, I was able to get an old inkjet printer. At that time itself I used a laser printer, so I was not very interested, but was curious to explore the cartridges and try to perform them reverse-engineering. I actually...

With the advent of Intel Core processors of the seventh generation many became clear that the strategy of "Tick-tock" that Intel should have all this time failed. The promise to reduce the technological process from 14 to 10 nm has remained a promise, began a long era of "Taka" Skylake, during which happened Kaby Lake (seventh generation), flash Coffee Lake (eighth) with a slight modification of process technology 14 nm to 14 nm+ and even Coffee Lake Refresh (ninth). It seems that Intel really needed a little coffee break. As a result, we have a number of different generations of processors, which are based on the same microarchitecture Skylake, on the one hand. And the assurances of Intel that every new processor much better on the other. Though not very...

Recently I came across a mysterious electronic component in a metal housing. From conventional integrated circuits differed appearance — were flatter and overall. What it is and what it eats, it became clear after the autopsy and reverse engineering of schemas. Before me was the operational amplifier, created for NASA in the 1960-ies with the use of hybrid technology. It turns out that the development of this component involved several important people in the history of semiconductors, and one of these operational amplifiers is on the moon. Read more →

How would you describe the year 2018? Was it the same as you expected? We would answer this question rather negatively. Since the most devastating natural disasters, and ending with a record number of women running in the elections, 2018 year has been full of surprises. Looking back, we appreciate the world is not as it seen in the predictions a few years ago. the advantage of the surprises is that they can often serve as a call to action. People may be concerned about the fact that reality did not match their expectations. Some surprises help people understand that the status quo needs to change. Some surprises underscore the fact that transformation has already begun. Twenty-five years ago, we read an article where it was written that hundreds of...

Hello! Today we want to talk about how he sees the VDI market vendor VMware. the Digitalization rules the world. In many companies there is no fixed working day, and even fixed workplace. Businesses need to employees have always been connected — at least, would read the mail and respond quickly to some events. That is picture perfect from the point of view of business is: the company has a convenient, transparent, secure access to work tools from any device from anywhere in the world. Read more →

Earlier, we did code reviews major mathematical packages such as Scilab and Octave, and calculators have been left as a small utility, which is difficult to prevent errors due to their small code size. We made the mistake of not paying attention to them. The case of publication the source code of the Windows calculator shown are all that interesting to discuss, what mistakes are hiding, but the error there is more than enough to write about it article. My colleagues and I decided to explore code a number of popular calculators and found that the code of the Windows calculator was not too bad (spoiler). Read more →

Guess it's over. https://twitter.com/JimBridenstine We need to consider all options to meet the Exploration Mission-1 target launch date of June 2020, including on launching commercial rockets. /We need to consider all options to achieve the target launch date for Exploration Mission-1 in June 2020, including the launch of commercial rockets./ The only commercial rocket, similar in parameters to the SLS, and that in principle it is possible to be certified for manned flight for the remainder of the year, called the Falcon Heavy. But even the Falcon Heavy, according to published reports, may not odnoosnom to send around the moon Orion KK, the total weight of 25,848 kg. Read more →

When I was still in school, in class 7, I had a cheap Chinese FM radio. It was a display and only 2 buttons to rewind to the station ahead and reset to the initial frequency of 88 MHz. I was happy, went, and was always listening to music from the radio. MP3 players only then began to appear and were very expensive. One day, a cool autumn evening, before bed flipping through radio stations hoping to sleep, I came across some, as I first thought, phone conversation. I started to listen, to understand, and after a few hours of listening I realized, this is not a phone conversation. Read more →

In the Autumn of 17 years was not only the Great October socialist revolution. In the fall of 2017, the state began the campaign of harassment online messenger- Telegam. First, from the creators of the messenger requested the keys that allow to decrypt all correspondence of its users, failure — sued him in court, and in the spring of ' 18, began the most ambitious in its absurdity and inefficiency — "Epic Wave Lock". In the process of these locks, there were large-scale failures in work of a huge number of online services, from small personal projects to banking services. ILV is not stopped, to this day, contrary to all laws, the Constitution and common sense, remain blocked millions of IP addresses. Yesterday in the channel Telegram was a message on...
