From the Translator: We have published an article by Maria Perna that discusses the typical JavaScript tasks most often offered to developer candidates during interviews. This article will be particularly useful for beginner programmers. Interviews at tech companies have long been the stuff of legend. It's no surprise — successfully passing an interview opens the door to a good job. But […]
The goal of this project was: To study the DHCP protocol while working in an IPv4 network To learn Python (a bit more than from scratch 😉 ) replacing the DB2DHCP server (my fork), the original here, which has become increasingly difficult to compile under the new OS. Moreover, I dislike that the binary, which cannot be 'swapped out right now', is expected to provide a functioning DHCP server with the option […]
In the view of the uninitiated, the job of a security administrator seems like an exciting duel between an anti-hacker and malicious hackers who continually invade the corporate network. Our hero deftly parries their bold attacks with swift command inputs in real time, ultimately emerging as the shining victor. Truly a royal musketeer, armed with a keyboard instead of a sword and musket. And on […]

An update numbered 1.6.1 has been released for the Telegram messenger, introducing a number of long-awaited features. In particular, this includes the ability to delete any message in a chat. This will remove the message from both users in a private chat. Previously, this feature worked only within the first 48 hours.

On the first day of spring (or the fifth month of winter, depending on your perspective), the submission period for KnowledgeConf — a conference on knowledge management in IT companies — came to an end. I must admit, the results of the Call for Papers exceeded all expectations. Yes, we knew the topic was relevant; we saw this at other conferences and meetups, but that it would uncover so many new facets and angles — […]
Any operation with big data requires substantial computing power. Regular data transfer from a database to Hadoop can take weeks or cost as much as an aircraft wing. Don't want to wait and spend? Balance the load across different platforms. One way to do this is through pushdown optimization. I asked leading trainer in Russia on development and administration of Informatica products, Alexey Ananyev, to share about […]
Abstract: Levels of IT infrastructure maturity within enterprises. Description of the advantages and disadvantages of each level individually.

The demonstrated application of reconnaissance techniques pertains to internal networks, which are isolated and not accessible from the outside. Such networks are typically present in even the smallest companies. The [...].
The Hinrich Foundation, an organization focused on international economic issues, published excerpts from an analytical report by AlphaBeta on the threats to China's economy by 2030. It is projected that retail and other trade in the consumer segment, including online, could generate approximately $5.5 trillion (37 trillion yuan) for the country over the next 10 years. This is about one-fifth of China's expected gross domestic product [...].
Recently, I was somewhat surprised to find out that in one of the departments of the large company where I work, launching SQL profiler during business hours is prohibited. I don't know how they manage to analyze performance issues that occur during business hours. Performance views often do not provide an accurate picture, especially if one or two procedures/queries are causing the slowdown without heavily loading the system. […]
