Good day, dear masters! This is my first article, I will try to be interesting. Many years ago (Oh the horror) when I was super energetic, young and eyes are burning I wanted to automate everything that moves and does not move. I felt your endless possibilities and was confident on 100% and more, in front of me there was not a single not a solved problem and burning in the hands. However, tracbar from youth to wisdom all moved towards the second. So with time came experience, which the son of errors difficult, and unfortunately, there's also the genius of paradoxes. Just looking ahead to say that many of the processes in the public service, where he worked and your faithful servant is automated, developed and put into operation a system which is...

Paragon Software has published a set of patches with full implementations of NTFS file system by opening the driver code under the GPL. The driver supports operation in read mode and in write mode. According to the developers, this implementation supports all the features of NTFS version 3.1.Now the driver uses a stripped-down implementation of the NTFS journal. But in the future Paragon Software adds support for the full journaling on top of the already built-in to the kernel generic block device JBD, which organized the journaling ext3, ext4, OCFS2.

Annually via cryptocurrency exchanges are millions of dollars of dubious origin. Often they belong to projects that later disappear with the users. Suffice it to recall the sensational case PlusToken, the founders who was deceived "investors" of three billion dollars. Team members are detained — is a consequence, but the stolen funds still not arrested. Attempts by regulators to get control of the crypto operations is not always effective. The situation has not changed after the entry into force of the Fifth EC Directive on combating money laundering (5AMLD). According to a report by research firm Peckshield for the last two quarters through the largest cryptocurrency exchanges have passed 147,000 BTC ($1.3 billion) received from suspicious addresses. The...

About the grants we found out the day of fools April 1, 2020. There was a lot of news propaganda wing with clickbaiting headers on how will help business and people in crisis. In fact, it has been found that will not all businesses and not all people. But I basically monitor all of the support packages, and I'm frankly infuriated by the inconsistency of the contents of the headers. In our office the last working day was March 13, and we still have another remote with the exception of the engineers of data centers. Any hope on getting real support was not. We've learned that the government usually only creates problems. Read more →

An Important component of protection against unauthorized access Every reasonable person has something to hide. This is normal. No one wants leaked his private keys to access the repository, important code or personal pictures in a reindeer sweater. So, I've thought about it and decided to gather in one place a standardized check-list for the comprehensive protection of your laptop. I deliberately cut stationary PC because they are less susceptible to threats of the "accidentally left in a bar". With 6 pounds of hard drives, heat pipes and tower cooler to make it much more difficult. I'll try to go through the main threats and methods of protection. For example, people often forget that to enter the password under the camera is a bad idea. I would be very...

Introduction As often happens, the database architect needs to develop a database for the specific solution. One Friday evening, returning on the train home from work, I thought, how would I have created a service for the recruitment in different companies. After all, none of the existing services makes it difficult to understand how suitable you candidate, you cannot create complex filters it is for specific skills, projects, and positions or exclude certain skills, positions and projects. The maximum that offer services are the filters by companies and partially by skill. In this article, I will allow myself to slightly dilute the strict technical presentation of the material, stir technical information non-technical real-life examples. In this example...

My name is Rostislav Salad, I work in the eSports organization for almost three years. Joined the company for the position of user experience designer, has grown to the UX lead, and are currently the grocery Manager. grocery Task Manager and approach to work we are very different from the responsibilities of product managers in other companies. This means that your company's ideas about the functionals and the set of skills for product Manager and designer may vary. For example, in some companies, the product Manager designs the interfaces, and we – no. the reason I raised this topic? We spent a lot of interviews with product designers. Based on my experience and the experience of colleagues, I can safely say that the question of the terms of reference asks...

RFC exists since 1969 — it was introduced during the discussion of the ARPANET. Then the engineer, Steve Crocker wrote RFC 1, on the software host. Since then it has been more than 50 years, but the Request for Comments is still in Vogue — published ~9 thousand documents on the network protocols, models of data storage and encryption algorithms. this diversity meet RFC that have no practical application. Wrote them mostly for fun. Today we will talk about some of the finds from this area. Read more →

We analyzed the data collected using container-honeypots — they were created by us to track threats. We found a significant activity of unsolicited or unauthorized miners cryptocurrency deployed as fraudulent containers with the use of published community of the image on Docker Hub. The image is used as part of the service that delivers malware-crypto currency miners. in addition, established programs to work with networks to penetrate in the open nearby containers and applications.

Author: Bart Hendricks, Monday, August 10, 2020 Warning — this is a Google translation.original an Early concept of the main mirror diameter of 2.4 m, which will be used for the Russian reconnaissance satellites of the new generation of "Hrazdan". (Source: journal Kontenant) currently, Russia has in orbit, there is only two existing satellite optical reconnaissance, the lifetime of which may have expired. They should be replaced by a more powerful satellites with a primary mirror about the same size as those believed to be installed aboard U.S. reconnaissance satellites, but it is unclear when they will be ready to fly. Experimental satellite launched in 2018 is probably the precursor of the much smaller constellation of spy satellites that will complement...

Entry, or where it is taken the Career programmer and engineer in General is a very interesting thing, and often leads to project management, as happened to me in T-Systems. Project management is beautiful: the experience, honor, and respect, but the scope for engineering activities there are to do. And the hands-that remember! (C) it Remains to use the obtained knowledge and skills in their outside projects, the good, it is. today I will tell in addition, I have a little (5-6 years old) saxophonist. And all is well in this beautiful instrument, but it is very loud it is. And with his first lessons, I dreamed about the appearance of my life of the same saxophone, but to be able to play it with headphones and not bother the neighbors, so it was sort of a...

In the last part it was shown the development process of the cylinder. In this we will focus on its materialization. At the beginning of this work I have had experience casting several hundreds of small parts made of aluminium casting and painful the last version of the cylinder, which was never finished. It managed to cast only from the fifth or sixth times, I do not remember... But in each set one-off forms had to spend about a month of work. The problem was in the capture of the air Gating system for pouring the metal has captured the air, which formed cavities in the body. Which only the Gating system I tried, which only Soviet cast Talmud did not read it was to no avail. And it would continued until I decided to try a radical solution — is inclined at...

Source: Vecteezy Yes, linear regression is not the only Quickly name five machine learning algorithms. it is Unlikely that you would call a lot of algorithms for regression. In the end, the only common algorithm of regression is linear regression mainly because of its simplicity. However, linear regression is often not applicable to real data because of too limited capacity and limited freedom of maneuver. It is often used only as a basic model for evaluating and comparing new approaches in research. the Team Mail.ru Cloud Solutions has translated an article in which the author describes 5 regression algorithms. They should have in their tool kit along with the popular classification algorithms such as SVM, decision tree and neural network. Read more →

When you buy a new car, you sit in it and hope that it will soar into the sky and fly over the traffic jam on the Avenue? Comes in a that it can replace a diesel generator in the country? If I want, without leaving the comfort of the cabin, to fish there in the summer from the middle of the river? No? So why a significant portion of customers want from the CRM system all at once: that she was sold and grew sales by 50%, oversaw employees and fined them, worked itself in built business processes based on machine learning and space technology, and then be issued the sound of the cash machine and counted salary for the entire company. Okay, the last she might not do, but the rest will. CRM is a very cool tool to say the multi-tool among software. Let's see how...
