In the Spring of 2017 on Habre (then at Geektimes) described the history of the 25-year-old mathematician and Professor at Moscow financial-legal Academy, Dmitry Bogatov, who spent three months in jail and then some time under house arrest basically because he was the operator of the output node of the Tor network (the address of its output nodes lit up among the addresses that are unknown publish extremist messages on social networks). Bogatov arrested and charged with two serious crimes, for which together provides for liability up to 22 years of imprisonment. History is rife with many inconsistencies, and outright fraud on the part of law enforcement. Tor Project then issued a statement sharply condemning the actions of law enforcement bodies of Russia...

Jeanine Guidry, Professor, school of media and culture Virginia Commonwealth University, together with colleagues in April published a study about the nature of talking about suicide in Instagram. The researchers found that...

TL;DR in Order to achieve high observability of containers and microservices, magazines and the initial metric a little. For a more rapid recovery and fault tolerance applications should apply the Principle of high observability (HOP, High Observability Principle). At the level of the application NOR requires: proper logging, careful monitoring, health checks and the performance trace/vias. as the item NOR use the check readinessProbe and livenessProbe Kubernetes.

All of modern design, web, typography, food, motion design is interesting because it combines the classical concepts of color and composition for the care of convenience of users. you Need to be able to draw icons, to figure out how in visual images to show actions or to explain the functionality, and constantly think about users. If you paint the logo or create identity, you have to convey the philosophy, the mood of the product, the emotions, and at the same time to count how the product will look consumers to consider how they will use it. So, designers that appeared at the beginning of the two thousandth were completely different. Now the designer is a universal soldier. The man who can go both in the digital and typographic design. Can do web, apps...

Hi, Habr! I can't afford to purchase traffic for mobile and desktop projects Mail.ru Group. Today in this post I will talk in detail about the traffic for games. It is written based on my presentation at the conference, The Big Deal. But first, a little about yourself. I worked with a huge number of projects on various marketing tasks, for the last year and a half working exclusively with mobile applications. During this time has worked with dozens of apps, most of which are in the soft launch, some of them are released in global, but several "rocked" more than $1 million turnover in a month. During the work I have formed a kind of vision, both from the point of view of traffic of the project to analyze the metrics and see if your project to grow, develop...

Smartphone Fairphone 3 the Dutch company Fairphone ("fair phone") believes that smartphones can and should be fully repairable. The second version of this device was released in 2015. Since the device is modular, you can replace the broken parts and buy batteries. At Fairphone there is no need to frequently release new versions, as do conventional producers, which are laid in planned obsolescence. the Third version of the apparatus has produced only four years later. A prototype of a Fairphone 3 fell into the hands of specialists in electronics repair from the company iFixit, and they made him a maximum score of 10 out of 10 see photos of the dismantling.

Audi showed a concept car AI:the Trail at the auto show in Frankfurt. The SUV looks futuristic: it is on the basis of the widely spaced wheels, composite body in the form of capsules are made of steel, aluminum and fiberglass doors are unusually open in different directions. The interior is minimalistic, but the steering wheel is not a wheel, and the wheel. But the thing that attracts attention is the absence of headlights, instead for the drones that light the way from the air. However, marker lights in place. Read more →

Continuing the series of articles about how Saint TeamLead Conf we are going to reveal the three most important block team-lead — work with a team, tools team-lead and development of awareness — today, talk about the topics which will be discussed in the format of private meetings, mitapov, master classes, round tables. the old TeamLead Conf in Moscow, we tried to highlight in a separate thread all round tables. Turned out pretty good (according to participants), but a lot of people wrote in the reviews that it would be good to narrow topics of conversation, to reduce the number of speakers to make the event more intimate, but at the same time get the opportunity to more deeply consider the topic, ask questions, listen to the opinion of colleagues. Said and...

Today we look at the Protocol link aggregation Layer 2 EtherChannel 2 level of the OSI model. This Protocol is not too different from the Protocol of the 3rd level, but before start learning about Layer 3 EtherChannel, I need to present you with multiple concepts, so the third level we will move later. We continue to follow the schedule of CCNA, so today we will discuss section 1.5 "setting, checking and faults Layer 2/3 EtherChannel" and subsections 1.5 and "Static EtherChannel", 1.5 b "Protocol PAGP" and 1.5 "Outdoor IEEE standard LACP". Before going further, we need to understand what EtherChannel. Let's say we have switch A and switch To, excessively United three lines. If you use the STP Protocol, two extra lines will be logically blocked to prevent...

The time period for reading the old journals helped me to identify the trial. In the late eighties and early nineties, AMD and Intel regularly meet in court. Initially, they exchanged technology. AMD produced under license from processors down to the 286-th (the second provider was a requirement IBM), but after the release of the Intel 80386, the situation has changed: the American manufacturer has decided not to share the developments with the AMD, and tried to ban the production of clones. Litigation finally ended only in 1996, Intel in General has lost, but managed to delay market introduction of the 386's processor from a competitor until March 1991. Trying to catch up, AMD is releasing the most powerful clone of the 80386 processor AM386DX with a...

IT-Alias — unique version of the classic Board game, game understanding and technical vocabulary. It made the engineers Badoo to play with the participants of conferences and our mitapov. And today we want to play in the IT Alias with readers Habra — and give a few hefty boxes of cards to those who are faster and more accurate than the call of the hidden words. Upd: thank you all for participating — 23 words guessed in just two hours! The results in the end of the post, but we offer don't stop and continue to play in the comments: make any words on IT themes. Read more →

AVR fairly cheap and widespread. I guess with them starting almost any embedded developer. And among lovers rules the ball Arduino, the heart of which is usually ATmega382p. I'm sure many wondered: how can you make them sound? If you look at existing projects, they are of several types: the Generators of square pulses. Generation using PWM or pull pins in the interrupts. In any case, it's a distinctive squeaking sound. the Use of external hardware MP3 decoder. the Use of PWM to output 8 bit (sometimes 16 bit) audio in the PCM format or the ADPCM. Since memory in microcontrollers for this is not enough, you usually use the SD card. Using PWM to generate sound based on the wave table, like MIDI. the Last type of all for me was particularly interesting...

Today we talk about the password recovery of routers and switches, upgrade, reinstallation and restoration of IOS and the Cisco licensing system for the operating system IOSv15. This is a very important topic relating to the management of network devices. How can I retrieve my password? You may wonder why you need it. Suppose you set up the device and installed all the necessary passwords on the VTY, console, in privileged mode on the Telnet connection and SSH, and then forgot the passwords. It is possible that the employee who installed it, quit and didn't give you record or you bought the router on eBay and don't know the password who set the former owner, so I can not access the device.

A Couple of weeks ago in our chat room appeared this message: And a little later — here it is: the author of the message — Eugene, programmer, head of the training Department and the electronics. In 5 years, he noticed that if you pull out the tape recorder motor, to connect the bulb and start to twist, the bulb will light. Six — what if the motor to change the polarity, it will spin in the other direction. At 18 he entered the innovative Measuring technology in Polytechnic. And at 24 he came to work in the "Siberix". This is to ensure that the purpose of the entire venture — not a Smart house and the station as such. The goal is to scratch hands (because itchy) and not allow them to oxidize (because of the gold alloy). So all who are perplexed, why waste...

The New version of Android (without the first "dessert" of the name) is already becoming available to users. As usual, at first only some: update get Google Pixel and Essential Phone and other device manufacturers it will appear later (if you're lucky). But this time the situation is more optimistic than usual: Google promises that have several partners, users will receive a "ten" to the end of the year (usually up to other manufacturers wave really dokatyvayutsya until next year). I Pixel upgrade has come so briefly felt innovations and wrote about what he saw. Read more →
