I like AI and have been working with the technology for over a decade. It’s been exciting, interesting, and inspiring — until recently.
As I write this in mid-February of 2026, software stocks are in freefall and social media is inundated with videos of AI company CEOs predicting the looming collapse of the software industry.
They tell us the story we’ve heard on loop for two years:
Built my own UART Web-Serial terminal.
Drew the mockups myself, read and edited the code. HTML/CSS — 99% AI generated, JS — roughly 80%.
Key feature: zero installation, works on locked-down machines. Open tab — plug in USB-UART — go. You can browse HABR and sniff UART simultaneously in another tab.
What makes it different
Unlimited export. Real-time packet counter for the future log file — instantly see how much you've captured.
No lag under load. Batched DOM updates, handles 500k+ log lines without freezing.
JSON scripts for automation. Useful when hardware needs precise handshake timing — describe command sequences in JSON, terminal executes with proper delays.
Multiple input fields with separate send buttons. Convenient for switching between frequent commands — no copy-pasting needed.
Hex input with auto-formatting. Automatic spaces, validation — no mental byte counting.
Packet grouping by inter-arrival time. Helps visually spot message boundaries when traffic is dense.
Custom baud rates. Beyond standard 9600/115200 etc. — enter any rate your hardware supports.
Technical details
Clean interface — only what actually matters from 20 years of HW/FW/Embedded experience. Vanilla JS, zero frameworks. Not for ideological reasons, just wanted no dependencies and minimal bloat.
Web Serial API provides direct COM port access through the browser — works in Chrome/Edge on desktop.
Might come in handy for flashing Arduino, debugging firmware, sniffing hardware communication.
LLMs fail at elementary math. Corporations spend billions, but ultimately are forced to attach calculators to computing machines of incredible power. All attempts to fix this via Chain-of-Thought, fine-tuning on arithmetic tasks, or context expansion have failed.
I conducted a series of experiments to understand why, and came to the conclusion that neural networks are simply not meant for discrete arithmetic. Their true purpose is continuous transformations.
This article describes the implementation of a novel neural network architecture that combines the precision of symbolic AI with the generalization capabilities of LLMs. As always, experiments and code are included.
Windows 11 is a modern and beautiful operating system, but sometimes it can run slower than you'd like. This is especially noticeable on older or less powerful PCs. The good news is that there are several simple and effective ways to improve system performance, making it faster and more convenient to use.
In this article, we'll look at how to properly configure Windows 11, get rid of unnecessary processes, and optimize its performance so that your computer runs smoothly and stably.
By the way, if you're interested in IT and useful tools, check out my Telegram channel. I regularly post fresh news, life hacks, and other useful things there. And now, to the heart of the article.
A major package of amendments to the Tax Code of the Russian Federation (hereinafter referred to as the Tax Code), draft federal law No. 1026190-8, may come into force on January 1, 2026. The law passed its first reading on October 22, 2025, and on November 10, revised amendments for the second reading were published, and it is these current changes that I have taken into account in this article.
Accessing Claude from Russia might seem like a daunting task due to the service's regional restrictions. In this article, I will explain in detail how to register for the web version and API of Claude, what tools are needed to bypass the restrictions, and how to use the service safely in the future. This guide is based on personal experience and includes registration methods that are current as of late 2024 and have been tested in practice.
After searching Russian-language resources, I realized that there is very little practically useful information, or it might not account for changes in the service's operation. Ordinary users have to gather information piece by piece - from various YouTube videos, forums, or superficial articles.
Therefore, I decided to create an up-to-date guide based on my personal experience and knowledge, taking into account all the pitfalls that an inexperienced Claude user might encounter.
I regularly choose various things for myself and always strive to get the best price/quality ratio. The warm season has begun, walks have become longer, and my new Redmi 13 Pro+ 5G, as luck would have it, doesn't have a headphone jack. This means it's finally time to buy myself a pair of TWS earbuds.
As a long-time audiophile with a FiiO M11 player and FiiO FH5 earphones, I have always avoided wireless headphones. Some 5-10 years ago, I tried early TWS models and, frankly, was disgusted—the sound quality was terrible. Since then, I haven't trusted wireless connections at all, preferring wired solutions.
In the previous article, we got acquainted with the Meshtastic project. We learned that it's possible to build your own radio chat based on a Mesh network, a regular smartphone, and a radio modem. The next logical questions people started asking were: What's next? How do I build this network? What should I buy?
The second part will describe several commercial kits for a Meshtastic modem from Aliexpress, their differences, and application features. If for some reason you are not interested in ready-made products, you can build a radio modem yourself. It's not difficult at all and is manageable even for the youngest and most novice radio amateur. Interested? Welcome to the second part under the cut.
November 20 marked the official launch Nano Banana Pro (Gemini-3-Pro-Image-Preview) with the powerful Gemini 3 Pro as its foundation. This is a more mature tool for design, infographics, and content. We will not only look at the new features and why this particular model is a breakthrough, but we will also see it in action with real examples.
DeepSeek is increasingly unavailable due to server overload. In this article, we will solve the problem in an original way – by installing Deepseek locally so that it works without any internet connection at all.
Hello, Habr! I once conducted a small test of virtual machines from various hosting providers and compared them with each other — it turns out that five years have passed since then. And in that test, the conditions for all servers were the same, as similar configurations were being tested.
Today I'd like to talk about how the cheapest (in the price range of 100 to 300 rubles) offers from popular hosting providers behave.
Not so long ago, about a year ago, I finally received my long-awaited package. Flipper Zero. For those who don't know, Flipper Zero is a small device that allows you to engage in all sorts of fun activities in life. The fun starts with the Sub-1 GHz antenna and continues with micro-scripts for PC. If you're interested, please read on.
Yesterday I wrote about the graphical shell Launcher for GoodbyeDPI, which allows you to intuitively use the GoodbyeDPI solution from ValdikSS to solve the problem of YouTube throttling and the unavailability of a number of sites in Russia. Everything was fine, but these were solutions only for Windows. In the comments, the main questions were about what to do with Android, Linux, and Mac, and why not in the source code. Alas, the repressions of the RKN (Roskomnadzor) force the Habr administration to censor articles, I am forbidden from making changes to yesterday's article, and the link itself is only available outside of Russia, so I am explaining about Android, Linux, and Mac here, with links to the source code.
So, for Android there are a lot of projects, I liked Release ByeDPI 1.0.0 · dovecoteescapee/ByeDPIAndroid · GitHub. For Mac and Linux I would install https://github.com/xvzc/SpoofDPI/releases. All in source code.
ByeDPI for Android is an application that runs a local VPN service to bypass DPI (Deep Packet Inspection) and censorship. A SOCKS5 proxy ByeDPI is launched locally on your device and all traffic is redirected through it.
In this guide, we will install the v2rayA package on OpenWRT using the stable 23.05.0. A router with at least 128 MB of RAM (256 is preferable) and more than 16 MB of storage is recommended (the installation takes about 30 MB of storage)
v2rayA is a simple-to-use and powerful client focused on Linux. Despite its name, the current version uses xray-core, although it's also possible to use v2ray-core. It has a web interface for managing settings and importing configurations and subscriptions. It supports everything that xray-core supports:
Shadowsocks (incl. 2022), ShadowsocksR, Trojan, Vless (including XTLS-Reality, XHTTP), Vmess, Juicity, Tuic
The guide will include:
1. Installation from the repository
2. Configuring v2rayA and bypassing blocks using Re:filter, Antifilter GeoIP, Geosite
The other day I was watching a video about artificial intelligence and its future development in editing software. It was a typical webinar: the speaker was showing off features in DaVinci Resolve while a talking head was broadcast in a small window.
And then I had the idea to write a post about the best screen recording programs. Many people need them: bloggers, teachers, online course sellers. Companies use them to create tutorials and send them to employees, and gamers record their gameplay.
I tested 11 options, and I'm sharing my thoughts in this review.
Wireshark is a widely used tool for capturing and analyzing network traffic, actively used for both educational purposes and for troubleshooting computer or network issues. Wireshark works with almost all OSI model protocols, has a user-friendly interface, and a convenient data filtering system. In addition, the program is cross-platform and supports the following operating systems: Windows, Linux, Mac OS X, Solaris, FreeBSD, NetBSD, OpenBSD.
Recently, I needed to run a VLESS subscription on Windows, make it work with my work VPN, and deal with all the associated 'joys.' I tried v2rayN, Nekoray, and Hiddify—and quickly realized I wanted to write my own client.
And so, singbox-launcher was born:
