Glory is only 11MB/sec away (2023)
One thing is certain in life: if you’re getting something for a steal, someone is getting screwed, and it’s probably you elsewhere. This isn’t an anti-capitalist rant, it’s just the truth. Companies don’t exist if they don’t make money. Unless there’s some innovation, rest assured that you’re overpaying somewhere else.

An IRC client in your motherboard
I made a graphical IRC client that runs in UEFI. It’s written in Rust and leverages the GUI toolkit and TrueType renderer that I wrote for axle’s userspace.

HTTP/2 Continuation Flood: Technical Details
Preface In October 2023 I learned about HTTP/2 Rapid Reset attack, dubbed “the largest DDoS attack to date”. I didn’t have deep knowledge of HTTP/2 back then.

Ethereum has blobs. Where do we go from here?
On March 13, the Dencun hard fork activated, enabling one of the long-awaited features of Ethereum: proto-danksharding (aka EIP-4844 , aka blobs). Initially, the fork reduced the transaction fees of rollups by a factor of over 100, as blobs were nearly free. In the last day, we finally saw blobs spike up in volume and…

Bump Allocation: Up or Down?
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…

ARM64EC (and ARM64X) Explained
ARM64EC (and ARM64X) Explained Probably the most confused looks I get from other developers when I discuss Windows and ARM64 is when I used the term " ARM64EC ". They ask is the same thing as ARM64? Is it a different instruction set than ARM64? How can you tell if an application is or ARM64 ARM64EC?

Hyprland Crash Course
For the past week I have been configuring hyprland and using it as my daily driver. Coming from major Desktop Environments like KDE or Gnome, this was definitely quite challanging, specially when implementing features that we take it for granted on these DEs, like screen sharing or screenshot annotating.
