A new version of the GDB debugger, 9.2, has been released, which offers only bug fixes compared to version 9.1. GDB supports source-level debugging for a wide range of programming languages (Ada, C, C++, Objective-C, Pascal, Go, etc.) on various hardware (i386, amd64, ARM, Power, Sparc, RISC-V, etc.) and software platforms (GNU/Linux, *BSD, Unix, Windows, macOS). Starting […]
Hello, Habr! My name is Maxim Vasiliev, and I work as an analyst and project manager at FINCH. Today, I would like to share how we processed 15 million queries in 6 minutes using ElasticSearch and optimized the daily load on the website of one of our clients. Unfortunately, I have to skip names as we have an NDA, but we hope that […]
Information technology allows us to access incredibly cool educational resources with just one click. For free. I'm currently tackling the challenge of how to sift through a massive amount of vital content to figure out what should be tried first, how to 'mark up the data' so that the neural network of the younger generation learns more effectively. (ontol.org, 'Burnout', 'Remote Work', Telegram channel). I present to you a complete selection of all free courses from […]
I 'scanned' 560 posts on Habr and (preliminarily) highlighted the top 10 most useful materials on emotional/professional burnout for myself.

Experience from the Best Startups of Y Combinator' Aaron Harris(YC): 'Coping with Founder Depression' Jonathan Blow: 'Techniques for Dealing […]

'If you're not ashamed of the first version of your product, you've entered the market too late' Hello everyone, I’ve been dragging my feet for a long time, and now I've decided to share not even an MVP, but the idea I’m currently working on. It crystallized a year ago, following 7 years of writing on Habr. Many have heard of the pyramid 'data-information-knowledge-wisdom.' Interestingly, the number of projects about data […]
The subject of this article is connecting external devices to a Mac via SAS, Fibre Channel (FC), eSATA interfaces. Let's clarify right away that there is a healthy pathway to solve the problem of accessing such devices: assemble a cheap PC, plug a SAS or FC HBA controller card into it (for example, a basic LSI adapter), connect your devices to this controller, and install any […] on the PC.
Checkpoint has introduced the Safe-Linking protection mechanism, which complicates the creation of exploits that manipulate the definition or modification of pointers to buffers allocated during a malloc call. While Safe-Linking does not completely block the possibility of exploiting vulnerabilities, it significantly complicates the creation of certain categories of exploits with minimal overhead, as in addition to the exploitable buffer overflow, one must find another vulnerability that causes information leakage about […]
From the Google Blog Editor: Have you ever wondered how Google Cloud Technical Solutions (TSE) engineers handle your support requests? TSE support engineers are responsible for identifying and resolving user-reported issues. Some of these issues are quite simple, but sometimes a request requires the attention of several engineers at once. In this article, one […]
The developers of OpenBSD have released a portable version of the OpenBGPD routing package 6.7, which can be used in operating systems other than OpenBSD. Portability has been achieved using code from the OpenNTPD, OpenSSH, and LibreSSL projects. In addition to OpenBSD, support for Linux and FreeBSD has been declared. OpenBGPD has been tested on Debian 9, Ubuntu 14.04+, and FreeBSD 12. The development of OpenBGPD is supported by the regional […]
An experimental release of the open WinAPI implementation — Wine 5.9 — has occurred. Since the release of version 5.8, 28 bug reports have been closed and 337 changes made. The most significant changes include: Significant progress in the development of the WineD3D backend based on the Vulkan graphics API; Initial support for splitting DLLs into PE format and Unix shared libraries (.so). Initial […]
We are increasingly receiving requests from clients to provide access to the Kubernetes cluster in order to interact with services inside the cluster: to connect directly to a database or service, or to connect a local application with applications inside the cluster… For example, there is a need to connect from one’s local machine to the service memcached.staging.svc.cluster.local. We provide this capability using […]
