Introduction With a sufficiently large and distributed infrastructure using DFS as a single point of access to data and DFSR for data replication between data centers and branch servers, the question of monitoring the status of this replication arises. It just so happened that almost immediately after starting to use DFSR, we began implementing Zabbix with the aim of replacing the existing zoo of various tools and streamlining monitoring […]
I'm starting a series of articles where I want to share my experience connecting Exchange and ELK. This stack will help process large volumes of logs without questioning at what scale traditional logging tools will cease to assist us. Let's get acquainted with a new player in the log arena. Exchange has a rather intricate logging system. The most sought-after logs are tracking logs, which monitor step-by-step progress […]
Usually, top-notch speakers who have 'devoured Docker and Kubernetes for breakfast' present at DevOps conferences, sharing their successful experiences with nearly unlimited resources from the corporations they work for. However, DevOps Live 2020 will be slightly different. DevOps blurs the lines between development and infrastructure, and DevOps Live 2020 blurs the boundaries between […]
Hello, Habr! We at 'Rexsoft' have translated the article Feature Selection in Machine Learning into Russian. We hope it will be useful for everyone interested in the topic. In the real world, data is not always as clean as business clients often believe. This is why there is demand for data mining and data wrangling.

The destination server must have a mailbox with the required login and password. Before using IMAPSync, it is essential to install it (https://imapsync.lamiral.info/#install). Due to the organizationās restriction on using employee mailbox passwords in the script, the migration process is handed over to the user. For […]
With this brief post, I would like to clarify a misunderstanding related to AWR analysis of databases running on Oracle Exadata. For almost 10 years, I've consistently encountered the question: What contribution does Exadata Software make to performance? Or, with newly coined terms: How much does Exadata influence the performance of a specific database? Often, the correct answer to this important question, in my opinion, is provided incorrectly […]

If you find it hard to differentiate between KDE and GNOME, or you can tell them apart but would like to know what other alternatives exist, then this article is for you. It's a review, and while it contains a lot of […]
Hello, Habr! Probably everyone has that little file where we stash something useful and interesting for ourselves. Links to articles, books, repositories, and manuals. These could be bookmarks in a browser or even just open tabs left for later. Over time, all of this accumulates, links stop working, and most of the materials simply become outdated. And […]
