With it, you can create backups of EC2 instances and store them in Amazon Simple Storage Service (Amazon S3) cloud storage, as well as create EC2 snapshot chains in native format. For […]
Hello Habr, this is MyOffice. The year 2019 was significant for us. More and more users trust us. The number of licenses sold is measured in hundreds of thousands, and over 1 million free licenses have been provided to the education system. The rapid growth in the number of clients prevents us from resting on our laurels. We are constantly improving the product, including working on unique features that […]
VACUUM can only 'clear' from a table in PostgreSQL what nobody can see — that is, there are no active queries that started before those records were changed. But what if there's an unpleasant type (a prolonged OLAP load on an OLTP database)? How can one clean an actively changing table in an environment with long-running queries without stumbling over the rake? […]
Long holidays are ahead, which means it’s time to revisit your Read later bookmarks or reread important articles from the past year. In this post, we have compiled and prepared a list of the most interesting materials from our blog for 2019 and hope you find them useful. The past year has been interesting and […]
I always thought I was slow-witted. More precisely, I thought I was a dimwit. This manifested simply: during meetings and discussions, I couldn't quickly come up with solutions. Everyone else was talking about something, sometimes insightful, while I sat there in silence. It was even a bit uncomfortable. Everyone else also thought I was slow-witted. As a result, I stopped being invited to meetings. They invited […]
The release of Zulip 2.1 has been introduced, a server platform for deploying corporate messengers suitable for facilitating communication among employees and development teams. The project was originally developed by Zulip and was made open-source after its acquisition by Dropbox under the Apache 2.0 license. The server-side code is written in Python using the Django framework. The client software is available for Linux, Windows, macOS, Android, and […]
After six years since the branch 4.0 was formed, phpMyAdmin 5.0 has been released, a web interface for managing MySQL and MariaDB databases. The application allows for managing databases, tables, columns, relationships within databases, indexes, users, permissions, executing SQL queries, importing and exporting data, visually viewing the structure, performing global searches across the database, and transforming stored data (for example, for viewing saved images) […]
The release of the Min 1.12 web browser has been published, offering a minimalist interface focused on addressing the address bar.

Barry Kauler, the founder of the Puppy Linux project, presented the experimental Easy Buster 2.2 distribution, which attempts to use container isolation along with Puppy Linux technologies. The distribution offers the Easy Containers mechanism for running applications or the entire desktop in an isolated container. The release of Easy Buster is based on Debian 10 package base. The distribution is managed through developed […]
In the previous article, we introduced the ELK stack and its components. The first task an engineer faces when working with the ELK stack is sending logs for storage in Elasticsearch for subsequent analysis. However, this is easier said than done; Elasticsearch stores logs as documents with specific fields and values, meaning […]
There is a large CHP plant. It operates as usual: burning gas, producing heat for heating homes, and electricity for the grid. The primary task is heating. The second is to sell all generated electricity on the wholesale market. Sometimes snow appears in freezing weather under clear skies, but this is a side effect of the cooling towers. An average CHP consists of several dozen turbines and boilers. […]
You are faced with the task of object detection again. The priority is to enhance speed while maintaining acceptable accuracy. You take the YOLOv3 architecture and finetune it. Accuracy (mAp75) exceeds 0.95. However, the processing speed is still low. Damn. Today we will sidestep quantization. Instead, we will look at Model Pruning — trimming excessive parts of the network to speed up inference without losing accuracy. Visually — from where, how much, and how […]
