Fil's Unbelievable Garbage Collector Fil-C uses a parallel concurrent on-the-fly grey-stack Dijkstra accurate non-moving garbage collector called FUGC (Fil's Unbelievable Garbage Collector). You can find the source code for the collector itself in fugc.c, though be warned, that code cannot possibly work without lots of support logic in the rest of the runtime and in the compiler. Let's break down FUGC's features: Parallel: marking and sweeping happen in multiple threads, in parallel. The more

That was fast. A week after a new feature for sharing long-form text was spotted in the Threads app, Meta is making the experiment official. Threads users will now be able to append text snippets of up to 10,000 characters to their posts in a feature Meta says is meant to support journalists and creators on the platform. As Engadget detailed last week, the feature is fairly basic for now. Selecting "text attachment" from the post composer opens up a simple text editor that has some formatting o

Threads challenges X by offering free support for up to 10K characters, plus prominent links

After recently being spotted testing a way to share longer text, Threads, Meta’s X competitor, is now officially rolling out the feature that allows users to attach up to 10,000 characters of text to their post. The addition has been designed with the needs of creators in mind, as it supports linking out to content outside of Threads, like newsletters, blogs, podcasts, and more. Before this update, Threads supported 500 characters — which is already far more than the 280 characters offered to X

Meta seems to be working on ways for Threads users to share long-form writing within a single post. Several users have reported seeing a new "attach text" feature on the service, which allows them to embed large chunks of text within a single post.

This post will cover the new design, and will also touch upon some of the unexpected and unintuitive performance characteristics of NVMe SSDs when it comes to read sizes. The index is already fairly large, but can sometimes feel smaller than it is, and paradoxically, query performance is a big part of why. If each query has a budget of 100-25

Threads crosses 400M monthly active users as it gains on X

Following a recent series of welcome updates as Threads turned two, Meta CEO Mark Zuckerberg announced today that his X competitor crossed 400 million monthly active users (MAUs), a 50 million boost since April. Zuckerberg’s announcement today was short, but significant: The last time Meta detailed its monthly active user number was on April 30, during its Q1 2025 earnings call, up from 320 million in Q4 2024 in late January.

In sledgehammer every operation is encoded as a sequence of bytes packed into an array. Every operation takes 1 byte plus whatever data is required for it. Each operation is encoded in a batch of four as a u32. Getting a number from an array buffer has a high constant cost, but getting a u32 instead of a u8 is not more expensive. Sledgehammer bindgen reads the u32 and then splits it into the 4 individual bytes. It will shuffle and pack the bytes into as few buckets as possible and try to inline
