D_Jul @ Habr 1 place · 09/30/2022 02:23 EDT

Коллективу Альфа-Банка и корпоративным коммуникациям больше 30 лет. За нашу историю накопилось огромное количество систем, которые внедрялись разными командами. Отпуска мы планируем в SAP HCM, командировку оформляем в SAP АХД, кандидатов ведём в E-Staff, обучение проходим в WebTutor — список внушительный. Что это значит для сотрудника? У каждой системы свой интерфейс, и нужно разбираться, где что находится. Неудобно.Неудобства проявлялись не так явно, когда команда собиралась в офисе. В нём проще... Read more ›

Add to bookmarks Don't show Habr

Nemets85 @ Habr 2 place · 09/30/2022 02:00 EDT

Я администрирую серверы на базе Astra Linux и хочу рассказать о своем видении настройки ALD домена: серверной части, клиентской, использовании файла hosts (по сравнению с DNS сервером). Также дам описание настройки резервного сервера. ALD мне интересен в первую очередь потому, что уже имеет интеграцию с Astra Linux. Статья будет вам полезна, если вы собираетесь узнать больше о Astra Linux не только из официальной wiki. Кроме того, эту операционную систему (вместе... Read more ›

Schlenz @ Habr 3 place · 09/29/2022 13:45 EDT

I thought my previous post rather funny, and was surprised seeing it initially receive so few views. I thought the entertainment flopped, but fortunately I was wrong. I therefore feel it my duty before my readers to address the subject of the Landau & Lifschitz proof of the invariance of the interval.You can find the summary of it in Wikipedia. Making their starting point the light-like interval always being equal... Read more ›

This question comes up for a lot of us as we trying to advance our career and reach new heights.

And today I want to share the compilation of things that I have found useful from the book. This... Read more ›

Even as I am posting this, I can see that my previous post received a hundred and twenty plus views, but no comments yet. I am saying again that my pursuit is not to give an answer, but to ask a question. I only wonder if there is in fact no answer to the questions I am asking – but anyway, I will continue asking them. If you know how... Read more ›

Let’s Discuss Relativity of Simultaneity

Schlenz @ Habr 1 place · 09/20/2022 08:27 EDT

There is one only too obvious problem with relativity of simultaneity in the way it is normally introduced, and I have never found an answer to it – what’s more, I never read or heard anyone formulate it. I will be grateful for an enlightening discussion.The framework of the thought experiment introducing relativity of simultaneity is this. Two rays of light travel in opposite directions and reach their destination simultaneously... Read more ›

e-Learning is an extension of/ alternative to a traditional classroom setup. e-learning, commonly known as ‘online learning’ or ‘virtual learning’ is ideally a one-way or two-way digital communication established on a device with video and voice call integration using internet access. The last two years made us realize how technology can facilitate and improve communication. Digital technology had its impact in almost every industry including the sensitive education sector.

It's alive

gekh @ Habr 1 place · 09/15/2022 11:31 EDT

I wonder why IT developer interviews are so strange most of the time. It feels as if the people are looking for computer science teachers, not engineers. All those theoretical questions that have no relation to the working reality. It is strange to be looking for eloquent teachers, who can perfectly explain any term or pattern, and then ask them to do the actual work. Maybe it is the imprint... Read more ›

The Positive Hack Days 11 forum, which took place May 18–19, 2022, was truly epic. The bitterly fought ATM hacking contest featured no fewer than 49 participants. How cool is that? The winner of this year's prize fund of 50,000 rubles, with the handle Igor, was the first to hack the virtual machines.

Generally, the most critical AS in the region is the dominant ISP on the market, but not always.As the number of alternate routes between ASes increases (the "Internet" stands for "interconnected networks" - and each network is an AS), so does...

Imagine someone withdrew money from a company's account at night. The next morning panic breaks out, leading to yet more problems. The IT department can reinstall a compromised system from scratch or restore it from backup. Reinstalling from scratch will wipe out all traces left by the attackers, and external investigators will have to search for clues in other systems. Restoring from backup carries the risk of accidentally reinstating a... Read more ›

Grow as a UX Designer by Learning Copywriting Basics

Add to bookmarks Don't show Habr

juliafjol @ Habr 1 place · 08/29/2022 08:16 EDT

Getting a task from a client, UX designers tend to pay attention to the design goals, not the contents of the website/app itself. There’s something completely wrong with it because the visual part might be superb, but when it frames a vague or wordy message, the client's goals won’t be reached.To avoid this, a UX designer should dive deeper into the content, analyze it, and restructure it in an interface-friendly...
