Hold on to Your Hardware: BadRAM

We’re living in unprecedented times, once again, in which holding on to our existing hardware has become more important than ever before. With prices for solid state drives and especially RAM going through the roof, it can be at the very least frustrating to have a computer malfunction due to faulty memory. In this post, I’d like to show how to check a system’s memory for defects and how to work around those defects to prolong a system’s life without needing to replace the RAM module(s), or worse the whole mainboard, right away.

GL.iNet Slate 7

If you happened to have stumbled upon my write-up almost four years ago about running an open source home area network, you might know that I’m enjoying a fairly elaborate and mostly FOSS-based infrastructure, that is as lightweight and travel-friendly as possible. Although many things have changed ever since and an update to the original post is well overdue, the fundamentals remained the same: My personal infrastructure has to be as flexible and portable as possible, to fit my ever-changing life.

One key component of my setup had been the Linksys WRT3200 ACM router running OpenWrt, an embedded Linux distribution designed primarily for network devices. The Linksys has been...

Видеорежимы в восьмибитных компьютерах. Coolsystem — Часть 2

В данной статье кратко рассмотрены видеоконтроллеры для следующих ретро-компьютеров: ZX Spectrum, Вектор 06Ц, Commodore 64, Commodore PET, Микроша, Радио-86РК, БК-0010, Агат (модели 7 и 9) и Апогей БК-01Ц.

Поскольку мой будущий самодельный компьютер их косвенно поддерживает, необходимо собрать информацию в одном месте.

Build a highly customizable mobile friendly HTML5 level selection screen controllable by tap, swipe and mouse wheel, written in TypeScript and powered by Phaser

A clean, fully paginated level selection system built in Phaser 4 with TypeScript, featuring horizontal drag, direction-aware snap, mouse wheel navigation and event-driven thumbnails. The UI components are fully decoupled from scene logic and designed with clear state separation. Complete source code available for download, ready to use and extend.

Hold on to Your Hardware

Tl;dr at the end.

For the better part of two decades, consumers lived in a golden age of tech. Memory got cheaper, storage increased in capacity and hardware got faster and absurdly affordable. Upgrades were routine, almost casual. If you needed more RAM, a bigger SSD, or a faster CPU or GPU, you barely had to wait a week for a discount offer and you moved on with your life. This era is ending.

What’s forming now isn’t just another pricing cycle or a short-term shortage, it is a structural shift in the hardware industry that paints a deeply grim outlook for consumers. Today, I am urging you...

Simulating rotating gravity and perimeter based movement like in “Be Brave, Barb” game with Phaser, without any physics engine

HTML5 platformer engine inspired by Be Brave, Barb, built without physics. Hero walks along a dynamically generated perimeter, switches between four gravity directions, and reattaches to surfaces using continuous collision detection. Everything is driven by pure geometry, vector math, and segment intersection.
