C3 solved memory lifetimes with scopes

news.ycombinator.com Unknown 2025-07-28 01:27:42

2025-07-11 Modern languages offer a variety of techniques to help with dynamic memory management, each one a different tradeoff in terms of performance, control and complexity. In this post we’ll look at an old idea, memory allocation regions or arenas, implemented via the C3 Temp allocator, which is the new default for C3. The Temp allocator combines the ease of use of garbage collection with C3’s unique features to give a simple and (semi)-automated solution within a manual memory management

The ChompSaw: A benchtop power tool that's safe for kids to use

Of all freestanding power tools, perhaps the jigsaw or scrollsaw would be the most fun for kids to use, as they allow freeform cuts. They're also pretty darn dangerous, with the jigsaw being powerful enough to remove fingers.

Table of Contents Introduction Recently I was looking at an issue on mimalloc, a "state-of-the-art" memory allocator developed by Microsoft. The issue was quite simple, developers wanted a way to preallocate a piece of memory and use it as mimalloc's heap. Seeing that mimalloc does not offer this feature, I thought: "how hard can it be to write a memory allocator to manage a preallocated region?". The answer to this question is: "given enough time, even a monkey with a typewriter can write

Ancient Roman Street Vendors Served Up Songbirds

A researcher working on the island of Mallorca found bones of song thrushes inside a trash pit near the ruins of an ancient fast food joint. The study, published in May in the International Journal of Osteoarchaeology, suggests that thrushes were commonly sold and consumed in Roman cities. This challenges the long-held belief that these small, speckled birds were a delicacy reserved for elite ban
