Good day to all!
3r3335. We had an open webinar last week as part of our 3-3338 course. Linux Admin
where Leonid parsed the quick configuration of Vagrant, as well as the possibilities and nuances of the joint use of Vagrant and Git.
3r3335. Questions and comments, as always, are waiting either here, or you can ask our teachers by going to Open Day .

How to reduce the number of experiments on animals

11/10/2018 10:31

Continuing previous topic about implants and prosthetics 3r3-360. An interesting technology of laboratory studies of the behavior of an orthopedic implant in conditions as close as possible to the human body was proposed by the same scientific group. The study can be conducted in vitro - that is, without the participation of laboratory animals.

3r366. Endoprosthetics - replacing a damaged joint or bone with a high-tech prosthesis is a complex operation, using the most advanced metal, ceramic and polymeric materials.

Career steroids

11/10/2018 09:31
A lot of books, films, articles and even songs are devoted to building a career. I read many of them - wonderful works. But Some are too correct, or something.

In the works of a lighter genre - for example, in songs and films - it is said about building a career much more prosaic, often with humor and irony. From what comes to mind immediately, I will name two songs - "Manager" groups Leningrad and, sorry for the idiom, The booty Gaza (the song is really called that),

But, as it should be for the light genre, there is no systematic approach, fullness, and examples from life...

How to patch find under FreeBSD?

11/10/2018 08:24


We teach FreeBSD to look for files by extended attributes

Summary: The FreeBSD OS has a file system-level control mechanism for extended file attributes (extattr). Using the standard commands setextattr, getextattr and rmextattr you can create, read and delete comments, keywords and other file metadata. But you cannot search for files by extended attributes. In addition, extended attributes are lost when copying a file. In two articles, I will offer my patches for the find and cp commands that eliminate these shortcomings. However, I am not a professional programmer ...[/h]

There is evidence of the presence of spyware chips in Supermicro

11/10/2018 07:25 servers. 3r3-31.  Where is a smart man hiding a leaf? In the woods. Where does he hide the spy chip? In server 3r336.  Only yesterday on Habré was r3r311. publishedAn article stating that there is no evidence of the presence of spyware in Supermicro hardware. Well, today they appeared . I found them in the equipment of one of the largest telecommunications companies in the US network security expert Yossi Applebaum.  The expert is one of the leaders of Sepio Systems, which specializes in the security of hardware solutions. Relatively recently, she fulfilled the order of one of the clients (whom ...

How to write in an assembler program with overlapping instructions (another bytecode obfuscation technique)

11/10/2018 05:22 We present to your attention the technique of creating assembler programs with overlapping instructions, - to protect the compiled byte-code from disassembling. This technique is able to withstand both static and dynamic analysis of bytecode. The idea is to pick up such a stream of bytes, when disassembling which starting from two different offsets, two different chains of instructions were obtained, that is, two different ways of executing the program. To do this, we take multibyte assembly instructions, and hide the protected code in the variable parts of the byte code of these instructions...

Convert words and phrases into an anagram

11/10/2018 04:35

Anagram (from the Greek. Ανα- - “per” and γράμμα - “letter”) is a literary device consisting in rearrangement of the letters or sounds of a certain word (or phrases), which results in another word or phrase 3r3155.
Anagrams are used to encrypt the answer to a quiz question (charade, crossword, etc.).

I bring to your attention two functions that implement the algorithm for obtaining anagrams from individual words and phrases.

The work of the functions “in combat”, as they say, can be seen in 3r3-316. here
