The story goes like this. ComputerCraft is a mod that adds programming to Minecraft. You write Lua code that gets executed by a bespoke interpreter with access to world APIs, and now you’re writing code instead of having fun. Computers have limited disk space, and my /nix folder is growing out of control, so I need to…
JPEG is a clever image compression algorithm that exploits a human perceptual bias and the structure of natural images. It makes a change of basis before encoding so that the rewritten image representation concentrates the signal that humans are most perceptive to, and thus, the remaining details can be discarded…
We’re excited to announce that Google will launch Chrome for ARM64 Linux devices in Q2 2026, following the successful expansion of Chrome to Arm-powered macOS devices in…
This one is going to be a quick one as there wasn't anything new discovered. In fact, I feel quite dumb. This is really a tale of " Do your research before acting and know what your goal is, " as you'll end up saving yourself a lot of time. Nobody likes throwing away work they've done either, and there could be…
143 vs 36 minutes is far too big difference
Python loses every public benchmark by 21-875x. I took the exact problems people use to dunk on Python and climbed every rung of the optimization ladder -- from CPython version upgrades to Rust. Real numbers, real code, real effort costs.
The FreeBSD Release Engineering Team is pleased to announce the availability of FreeBSD 14.4-RELEASE. This is the fifth release of the stable/14 branch.
Why 'indirection has a cost' is usually the wrong reason to inline and what actually costs you.
In the previous article we explored how Go’s memory allocator manages heap memory — grabbing large arenas from the OS, dividing them into spans and size classes, and using a three-level hierarchy (mcache, mcentral, mheap) to make most allocations lock-free. A key detail was that each P (processor) gets its own memory…
FFmpeg is truly a multi-tool for media processing. As an industry-standard tool it supports a wide variety of audio and video codecs and container formats. It can also orchestrate complex chains of…
How ParadeDB uses principles from search engines to optimize Postgres' Top K performance.
Introduction An obscure quirk of the /proc/*/mem pseudofile is its “punch through” semantics. Writes performed through this file will succeed even if the destination virtual memory is marked unwritable. In fact, this behavior is intentional and actively used by projects such as the Julia JIT compiler and rr debugger…
NOTE June 2026: Hetzner announced over 100% increases in prices. They will honour old prices for instances built before June 15th 2026, but for new instances the performance/price ratios show below are no longer valid.

Back in January, the ThunderScope team sent me a PCIe card version of their prototype open hardware oscilloscope.
what's a few systemd services in initramfs between friends?
Let's talk about the "Windows Baseline Security Mode," too.
Rust struct serialization problem caused by many nullable SQL columns.
Maybe the code shouldn't be the only documentation?
What makes BEAM and OTP different from async/await, threads, and actors. Process isolation, supervisors, and why Erlang's model keeps winning 40 years later.
Why is my first C++ (m)allocation always 72 KB?? It’s the ’emergency pool’ for exceptions, here’s how I uncovered it using GDB and digging through the source code of libstdc++, glibc and Valgrind!
Although I have to have a machine running macOS Tahoe to support our customers, I personally don't like the look of Liquid Glass, nor do I like some of the functional changes Apple has made in macOS Tahoe.
The memory management in DOS is simple, but that simplicity may be deceptive. There are several rather interesting pitfalls that programming documentation often does not mention.
Discover how Bootc and OSTree are revolutionizing Linux system deployment, offering modern, efficient, and immutable management.
A dive into the spectrum of sandboxing and isolation, from Linux namespaces and gVisor to hardware-enforced microVMs and WebAssembly, and why picking the right boundary matters for multi-tenant workloads.
A description of some of the recent changes to do allocations on the stack instead of the heap.
How good is the random_page_cost default, and should you lower it on modern flash storage?
The author of Java 26's MemoryMXBean.getTotalGcCpuTime() analyzes the CPU-memory trade-off and why pause times fail to capture explicit GC cost.
