This is a completely useless, impractical, yet amusing little post about directories in *nix systems. It’s Friday after all. During interviews, boring questions about inodes and everything-is-a-file often arise, which few can answer sensibly. But if you dig a little deeper, you can find some interesting things. To understand the post, here are a few points: everything is a file. A directory is also […]
We often discuss energy-saving opportunities in data centers through thoughtful equipment placement, optimal cooling, and centralized power management. Today, we will talk about how to save energy in the office. Unlike data centers, electricity in offices is needed not only for equipment but also for people. Therefore, achieving a PUE ratio here around […]
The Webalizer utility and Google Analytics tool helped me for many years to get an idea of what happens on websites. Now I understand that they provide very little useful information. With access to my access.log file, figuring out statistics is very simple and requires only basic tools such as sqlite, html, SQL, and any scripting […]
At the end of July, developers released the long-awaited version of one of the best content management systems—Plone. Plone is a Python-based CMS using the Zope application server. Unfortunately, it is relatively unknown in the post-Soviet space, but widely used in educational, governmental, and scientific circles worldwide. This is the first release fully compatible with Python 3, and work on […]
Welcome, Habr! Once upon a time, we were the first to introduce the Kafka topic to the Russian market, and we continue to monitor its development. In particular, we found the interaction between Kafka and Kubernetes interesting. An overview (and quite cautious) article on this topic was published in the Confluent company blog last October, authored by Gwen Shapiro. Today, we […]
The biggest transport problem in St. Petersburg is the bridges. At night, you have to rush out of the pub before finishing your beer because of them. Or pay twice the usual taxi fare. In the morning, you need to carefully calculate your time so that as soon as the bridge opens, you can quickly make it to the station like a nimble mongoose. The option of ‘staying somewhere in the center near the station’ is not […]
A collection of interesting statistical facts inspired by posts from my Telegram channel Groks. The research results described below once changed my perception of venture capital and the startup environment. I hope these observations will be useful for you too, especially for those who view capital from the perspective of founders. 1. The startup industry is fading in the face of globalization. Young companies aged less than […]
If I were to award a Nobel Prize to Jean Tirole, I would do so for his game-theoretical analysis of reputation, or at least include that in the description. I think it’s one of those cases where our intuition aligns well with the model, even though it's hard to validate that model. It falls into the category of models that are difficult or impossible to verify and falsify. But the idea seems completely […]
Despite the fact that Intel has yet to release the long-awaited 10nm Ice Lake processors, it is already actively working on their successors — Tiger Lake. One such processor was discovered by the well-known leak source under the pseudonym KOMACHI ENSAKA in the UserBenchmark performance testing database. To start, let's remind that the release of the Tiger Lake processors is expected in […]
The release of the Duktape 2.4.0 JavaScript engine, aimed at embedding in the codebase of C/C++ projects, has been published. The engine is characterized by its compact size, high portability, and low resource consumption. The source code of Duktape is written in C and is distributed under the MIT license. The Duktape code occupies about 160 kB and consumes only 70 kB of RAM, and in low memory consumption mode, it is 27 kB […]
The Windows 10 operating system includes various troubleshooting tools that allow you to either save files or perform a clean reinstall of the system. However, it seems that the folks in Redmond are experimenting with other recovery formats. After all, a bootable USB drive or DVD is not always at hand, nor is there access to another computer. In the latest build of Windows 10 Insider Preview, numbered 18950, a section was discovered […]
