A tale about exploiting KernelCTF Mitigation, Debian, and Ubuntu instances with a double-free in nf_tables in the Linux kernel, using novel techniques like Dirty Pagedirectory. All without even having to recompile the exploit for different kernel targets once.
Bringing the great successes of financial engineering to Rust.
An in-depth analysis that explains how this console works internally
New research supported by Wu Tsai Neurosciences Institute could lead to novel treatments for

Talk is cheap, show me the code Introduction A common problem my friends and I have is receiving actionable emails whose priorities are medium level. They do require action of some sort ($ \geq lowest\ priority$), but the action is due in the near future ($\leq highest\ priority$). I tend to skim over these emails…
How a thinker who hated trends & fashions became trendy & fashionable
Our work shows that it is possible to trigger Rowhammer bit flips on DDR4 devices on AMD Zen 2 and Zen 3 systems despite deployed TRR mitigations. This result proves that AMD systems are equally vulnerable to Rowhammer as Intel systems , which greatly increases the attack surface, considering today’s AMD market share…
esbuild and Redis1 are two examples of codebases with exceptional documentation. Through their READMEs, changelogs, architecture documents, and code comments, both projects explain their design in such a way that someone new to the codebase can understand where things are, how things are done, and why they are done…
Apple is being sued by the DOJ, but most of the complaints aren’t about the App Store. I think, though, Apple’s approach to the App Store is what led to this case.

Thoughts and more by Tom Lingham
More than 60 percent of Ohio’s driver’s license suspensions do not stem from bad driving; instead, they arise because the driver owes an unpaid debt. Debt-related suspensions (DRS) could prevent people from getting to work where they could make the money needed to repay the debt. In this report, we investigate whether…
Back in 2019, Nick Fitzgerald published always bump downwards, an article making the case that for bump allocators, bumping “down” (towards lower addresses) is better than bumping up. The biggest reasons for this are bumping up requires 3 branches vs 2 for bumping down and rounding down requires fewer instructions…
A month ago, I flew from London to NYC, paid $3500 for a Vision Pro headset at Apple Fifth Avenue, and flew back home. I’ve been using it every day since — here’s what I think. My background, for context: I’ve been working in AR for many years. I built...
A brief introduction to antennas, superheterodyne receivers, and signal modulation schemes.
Backpressure is something nearly every software engineer will have to deal with at some point, and for some it’s a frequent problem. But…
A Hubris Bug Story
A common refrain is that threads can do everything that async/await can, but simpler. So why would anyone choose async/await?
I have this weird hobby of trying to get good unix tools to run natively on Windows. I find this is the most efficient use of my laptop's resources, and therefore the nicest experience. WSL is nice, but it takes up a lot of RAM on my system. I prefer to use MSYS2 . Getting unix tools to work correctly under MSYS2 is a…
Sometimes you have a pointer to a class, and you want to invoke a method. You can use the -> operator for that.
I implemented search and filtering for entities on our product at epilot. The users were heavily using the feature, however, a unique issue surfaced: difficulties in filtering file names containing diacritical marks like umlauts (Äpfel, über, schön, etc.).
