⚙️ Engineering¶

1. Aggressive caching for a Mastodon reverse proxy: what to cache, what to never cache, and why content negotiation will eventually betray you¶

Link — it-notes.dragas.net · 13h ago · ⭐ 22/30

The author details an aggressive caching strategy for a Mastodon instance (mastodon.bsd.cafe) using nginx on FreeBSD, explaining what to cache (public, static assets) and what to never cache (user-specific, authenticated content). A key finding is that HTTP content negotiation (for different media types like JSON vs. HTML) can break caching if not handled carefully, leading to stale or incorrect responses. The configuration shared achieves significant load reduction on the application server. The author concludes that with careful rules, a reverse proxy can absorb the vast majority of public, repetitive requests.

🏷️ Mastodon, caching, reverse proxy, content negotiation

2. Quoting Andreas Kling¶

Link — simonwillison.net · 11h ago · ⭐ 21/30

Andreas Kling announces that the Ladybird browser project will no longer accept public pull requests due to the rise of AI-generated code. He argues that a substantial patch is no longer a reliable proxy for good faith effort, as AI can produce large amounts of plausible-looking code. The project will now require contributors to be directly responsible for changes they introduce. Kling concludes that for a browser targeting real users, code provenance and accountability must take priority over open contribution volume.

🏷️ open source, pull requests, AI-generated code, maintainer trust

3. Rotation revisited: Cycle decomposition in clang’s libcxx¶

Link — devblogs.microsoft.com/oldnewthing · 1 days ago · ⭐ 19/30

Raymond Chen explains how clang's libc++ implements array rotation using cycle decomposition to achieve the minimum number of element moves. The technique works by tracing the permutation cycles of the rotation operation and moving elements directly to their final positions. This approach is more efficient than naive methods like repeated single-element shifts. Chen concludes that while mathematically elegant, cycle decomposition is primarily useful when element moves are expensive, such as with non-trivial types.

🏷️ rotation, cycle decomposition, libcxx, clang

4. Using Safetensors with Flax¶

Link — gilesthomas.com · 23h ago · ⭐ 18/30

The author documents porting PyTorch LLM code to JAX/Flax and needing to use Safetensors for checkpoint storage. Despite Safetensors' official docs lacking a JAX implementation, the trick is to use the safetensors.flax module (from the safetensors Python package) which works seamlessly with Flax models. The key insight is that safetensors.flax exists and is functional, even though it's not prominently documented, solving the checkpoint compatibility issue between PyTorch and JAX.

🏷️ Safetensors, Flax, JAX, checkpoints

5. JAX backends and devices¶

Link — gilesthomas.com · 3h ago · ⭐ 18/30

While porting PyTorch LLM code to JAX, the author encountered a CUDA out-of-memory error when loading a 19GiB dataset (10.2 billion 16-bit integers) using safetensors.flax.load_file. The error occurred because JAX's default device placement tries to load the entire tensor onto a single GPU. The solution involves using jax.device_put with sharding or loading data in chunks to distribute across available devices, highlighting a key difference in memory management between PyTorch and JAX.

8. Checking in on Perplexity¶

Link — daringfireball.net · 7h ago · ⭐ 20/30

John Gruber revisits his earlier skepticism about Apple acquiring Perplexity AI, noting that the startup has since slipped into the 'afterthought' tier of AI companies. He references ongoing negative press and declining relevance, arguing that Perplexity's rumored acquisition talks with Apple are more likely seeded by Perplexity itself than by Apple executives. Gruber concludes that Perplexity's current position makes it an unlikely and unattractive acquisition target for Apple.

9. Nieman Journalism Lab: Twitter/X Punishes Accounts That Post Links¶

Link — daringfireball.net · 1h ago · ⭐ 18/30

Nieman Journalism Lab analyzed 200 recent tweets from 18 large publishers (6 paywalled, 9 free) on X and found that posts containing links receive significantly lower engagement (likes + comments + retweets) than those without. The analysis suggests X's algorithm actively suppresses link-containing posts, harming news publishers' organic reach. Paywalled publishers like Bloomberg and NYT were among those affected, while non-paywalled outlets like BBC and Reuters saw similar penalties. The core finding is that X's algorithm devalues link-sharing, undermining a primary traffic driver for news organizations.

🏷️ Twitter, X, engagement, publishers

10. Elon Musk’s X Is a Freak Show¶

Link — daringfireball.net · 2h ago · ⭐ 18/30

Nate Silver analyzes a bubble chart of X's most-engaged accounts in February 2026, finding the platform's top traffic is dominated by low-quality, highly partisan accounts he had never heard of. He argues that X's remaining engagement is a 'freak show' of extreme content, with mainstream or quality accounts largely absent from the top ranks. The data suggests the platform's algorithm rewards outrage and partisanship over substance, accelerating its decline into a niche space for toxic engagement.
