Donald Knuth is a computer science scholar who cares so much about the correctness of his books that he offers a hexadecimal dollar ($2.56, 0x$1.00) for any found "mistake," where a mistake is anything that is "technically, historically, typographically, or politically incorrect." I really wanted to receive a check from Knuth, so I decided to look for errors in his outstanding work "The Art of Computer Programming" (TAOCP). I managed to find […]
If you don't understand what DevOps is, here's a brief cheat sheet. DevOps is a set of practices that reduce engineers' fears and decrease the number of failures in software production. Generally, they also shorten the time to market — the period from idea to delivering the final product to customers, allowing for quick business experiments. How to start a DevOps transformation? […]
AMD's CEO Lisa Su stated at the annual shareholders' meeting that advanced packaging solutions, such as the use of 'chiplets', will be one of the foundations of the company's success in the future. Chief Technology Officer Mark Papermaster highlighted current issues facing the semiconductor industry in the latest episode of The Bring Up series created by AMD's press service. Mark stated, […]
I've long wanted to write about how I store my files and make backups, but I've just never gotten around to it. Recently, an article appeared here that's somewhat similar to mine but with a different approach. The article itself. For many years, I've been trying to find the perfect method for file storage. I think I've found it, but there's always […]
Last Saturday, May 18, Jerry Gamblin from Kenna Security checked 1,000 of the most popular images on Docker Hub for the password used for the root user. In 19% of cases, it was empty. Background on Alpine The trigger for this mini-research was the Talos Vulnerability Report (TALOS-2019-0782) that was published earlier this month, which the authors — thanks to the discovery by Peter […]
How to configure OpenLiteSpeed for reverse proxying in Nextcloud, which is located on the internal network? Surprisingly, a search on Habr for OpenLiteSpeed yields nothing! I hasten to correct this injustice, as LSWS is a worthy web server. I love it for its speed and stylish web administration interface: Despite being most famous as a 'accelerator' for WordPress, in today's article I […]
Jerry Gamblin decided to investigate how widespread a recently identified issue is in the Docker images of the Alpine distribution, related to setting an empty password for the root user. Analysis of a thousand of the most popular containers from the Docker Hub catalog showed that in 194 of them (19.4%), the root user has an empty password without the account being locked ("root:::0:::::" instead of "root:!::0:::::"). In case of usage in […]
Hello, friends. In anticipation of the launch of the course "Backend Developer in PHP", we traditionally share with you a translation of useful material. Software is solving more and more everyday tasks while becoming increasingly complex. As Marc Andreessen once said, it is eating the world. As a result, over the past few years, approaches to application development and delivery have seriously […]

Currently, the topic of DevOps is trending. Continuous integration and delivery CI/CD pipelines are being implemented by all who are interested. However, many do not always pay enough attention to ensuring the reliability of information systems at various stages of the CI/CD Pipeline. In this article, I would like to discuss my experience in automating software quality checks and implementing possible scenarios for its "self-recovery." Source […]
The release of the in-memory data caching system Memcached 1.5.15 has taken place, which operates with data in key/value format and is characterized by its ease of use. Memcached is commonly used as a lightweight solution to speed up the performance of high-load websites by caching access to databases and intermediate data. The code is distributed under the BSD license. The new version features experimental support for authentication with the ASCII protocol. Authentication is enabled […]
It has been over a year since the discovery of Spectre and Meltdown, and the processor market has been in turmoil due to the discovery of new vulnerabilities related to speculative execution. The most affected were Intel chips, including the latest ZombieLoad. Of course, AMD seized the opportunity to emphasize the security of its CPUs. On the page dedicated to Spectre-like vulnerabilities, the company proudly stated: “We at AMD […]
