Multi-variable optimization is an incredibly useful tool for writing software. It allows you to specify a desired result and delegate finding the solution to a reliable algorithm. If you know what you want but not how to get it, optimization can probably help. Problems with many interacting variables that are…
Lately I’ve been thinking about Stephan Berger’s recent blog post on hiding Linux processes with bind mounts. Bottom line here is that if you have an evil process you want to hide, use …
Now they’ve gone an done it. An unidentified agency has spread a potent computer virus across all the world’s computers and deleted the binaries for every copy of every software development tool. Even the offline copies — it’s that potent.
Almost every traditional database keeps its write-ahead log and data files on one machine's disk, which is the root cause of data loss risk, expensive read replicas and high-availability clones, and analytics queries that drag down transactions.
Technical maxims that define Urbit's approach to engineering.
Improving software memory safety is a key security objective for engineering teams across the industry. Here we begin a journey into the XNU kernel at the core of iOS and explore the intricate work our engineering teams have done to harden the memory allocator and make our software much more difficult to exploit.
If I navigate to https://blog.cloudflare.com/, my browser will connect to a remote TCP address from the local IP address assigned to my machine, and a randomly chosen local TCP port. What happens if I then decide to head to another site?
This post is best described as a technology demonstration; it melds together web servers, plugins, WebAssembly, Go, Rust and ABIs. Here's what it shows:
Why TOAST is the best thing since sliced bread
This post explains how CAP-Consistent systems can be highly available, how the CAP theorem applies to CockroachDB, and why consistency is the better choice.
The detailed story of how to build a vector-based storage model from scratch.
CUDA grep : Manish and Brandon's 15418 final project
A few weeks ago I criticized a proposal by Antirez for a hypothetical linearizable system built on top of Redis WAIT and a strong coordinator. I showed that the coordinator he suggested was physically impossible to build, and that anybody who tried to actually implement that design would run into serious problems. I…
As it turns out, font rendering is a highly controversial topic. If you don’t see anything wrong with Linux font rendering, please disregard this as a shitpost. Thanks.
I am lucky in that I have a few side projects which have grown up to become full fledged companies. One of them builds little tools to detect different types of financial crime.
TL:DR Successive, well intentioned, changes to architecture and technology throughout the lifetime of an application can lead to a fragmente...
Google Cloud will now offer the ability to encrypt data in use, while it’s being processed in a Google data center
In this article I share the results of a home-lab experiment in which I threw some different problems at ZFS, Btrfs and mdadm+dm-integrity in a RAID-5 setup.
If you’ve spent any amount of time at a Unix command line you’ve probably already seen xargs . In case you haven’t, xargs is a command used to execute commands based on arguments from standard input.
Wettbewerb um die ultimative Mindestanforderung für Windows XP zu finden.
tl/dr: it can deliver big performance speedups at modest area cost
The Microvium JavaScript engine for microcontrollers takes less than 16 kB of ROM and 64 bytes of RAM per VM while idle, making it possibly the smallest JavaScript engine to date with more language features than engines 4x its size
