notebook speakers.   Using ordinary sound and ultrasound, attackers can disrupt the process of reading or writing data with a hard disk. Also, this method can be used to disrupt the launch of the operating system, and in some cases, to damage the hard drives. This conclusion was made by a group of specialists in information security based on a series of their own experiments.  In this case, especially complex devices are not needed, they are almost suitable means. In order to perform a sound attack, you need local sound sources, the purpose of which will be a hard disk. The source can be ordinary low-cost speakers ...

When working with databases there is a problem that is called "SELECT N + 1" - this is when the application instead of one query to the database that selects all the necessary data from several linked tables, collections, makes an additional subquery for each result row of the first query, to get related data. For example, first we get a list of students of the university, in which its specialty is identified by an identifier, and then for each of the students we make an additional subquery in the table or a collection of specialties in order to get the name of the specialty by the specialty ID...

Michael DeHaan is the person who created Ansible. Many things that system administrators, release- and DevOps-engineers do on a regular basis are, to put it mildly, uninteresting. DeHaan wants these people to free their time for more interesting things (at work or outside the office door), and wrote a product code that frees administrator time.

With the end of 201? in which the Ryzen processor became one of AMD's most successful products, a logical question arose: what next? In early 201? plans were voiced: Ryzen of the second generation should appear in the middle of the year, after which the second generation of Threadripper will be released, at the 12-nm process GlobalFoundries. This is not the next new AMD microarchitecture, which, as we know, will be Zen 2 on the 7 nm process technology. This release of components with some improvements, plus the ability to use a manufacturing process that allows you to raise the frequency and performance ...
