I know this is an old comment, but I'm curious what manufacturer you're referring to - is it Lepin?

> unless you feed it source

Which isn't particularly difficult - the language docs and std source come with the installation, so all you need to do is tell Claude where those directories are in your skill/plugin/CLAUDE.md.

> and guide it closely (in which case it's useful for focused work)

It does struggle sometimes with writing code that compiles and uses the APIs correctly. My approach to that so far has been to write test blocks describing the desired interface + semantics, and asking Claude to (`zig test` -> fix errors) in a loop until all the tests pass.

Perhaps not every aspect of the query plan can be dictated, but both MySQL and Postgres (with pg_hint_plan) allow you to specify hints that enforce specify join order and scan behavior for the tables in your query, which is where the majority of "unexpected change in query plan" problems will arise. As for SQLite, I'm less familiar with the knobs available for query tuning, but a cursory Google tells me that join order is respected when using CROSS JOIN, and index usage can be forced with INDEXED BY/NOT INDEXED.

The cost plan is a crude approximation of the actual query cost. Sometimes, the query planner makes a terrible guess. Your resident DBA won't appreciate being sometimes paged at 3 AM on a Sunday. A good strategy is to freeze the query plan once you have sufficient sample size of data in the involved tables.

As a corollary, will we see a recurrence of congestion in the middle as FttH sees increased adoption? It's easy to believe that 10 Gbps ought to be enough for everyone, but history tells us that people will find a way to saturate any unused bandwidth (8K video with crazy bitrates, 1 TB video game installs, etc).

That's why you sandbox. You can mitigate most low-hanging DoS fruits by running your server side hooks in a per-tenant cgroup that limits CPU and memory usage. One tenant per public key for trusted contributors, and one general-purpose tenant shared by all new/unknown contributors.

Exponential search is useful when you're querying a REST API that addresses resources with sequential IDs, and need the last ID, but there's no dedicated endpoint for it:

  HEAD /users/1 -> 200 OK
  HEAD /users/2 -> 200 OK
  HEAD /users/4 -> 200 OK
  ...
  HEAD /users/2048 -> 200 OK
  HEAD /users/4096 -> 404 Not Found

And then a binary search between 2048 and 4096 to find the most recent user (and incidentally, the number of users). Great info to have if you're researching competing SaaS companies.

You can use a pre-receive hook on a git server to reject pushes that fail compilation. Downside is that it requires admin access on git forges, so you're only able to do this if you self-host.

It can work. Old School RuneScape runs almost entirely on nostalgia, but the community voting system they have for introducing new content keeps the game alive and fresh, even after 20 years.

Nothing stops you from adding a PRNG seed parameter to initialize your deterministic game engine.

If be curious to see what the IPv4/IPv6 breakdown looks like when looking at HTTP/2 and HTTP/3 connections only, which should exclude the vast majority of crawlers.

Definitely not for the biggest ones. Google and Meta have so many machines in their data centers that IPv6 addressing becomes a technical necessity due to the risk of exhausting the RFC 1918 address space. Naturally, they were early adopters of IPv6.

If SIP is kicking in, it sounds like you're using the clang that comes with Apple's developer tools. Does this same issue occur with clang sourced from homebrew, or from LLVM's own binary releases?

One or more of:

* Incorrect, or lack of, drag

New comment by 10000truths in "Finding all regex matches has always been O(n²)"

10000truths — Mon, 23 Mar 2026 21:00:37 +0000

Restricting regex features to guarantee time complexity works, but it requires sacrificing potentially useful features like backtracking (or in the article's case, constraining oneself to fixed-upper-bound-length needles).

In a real-world deployment where you want to run any arbitrary regex in an idiot/malice-proof manner, the best solution is the same solution you'd use for running any other kind of untrusted code - sandbox it! A good regex API should limit its execution time and memory consumption and return a timeout error in case those limits are exceeded. Ideally, those parameters would be configurable at the API level. Unfortunately, the only regex libraries I know of that get this right are .NET's standard library Regex API and the third-party regex package in Python.

New comment by 10000truths in "Our commitment to Windows quality"

10000truths — Fri, 20 Mar 2026 23:05:34 +0000

Windows' value is as a funnel to the Microsoft platform. Starving that funnel of attention might not have an immediate effect, but it's a slow death spiral for the company because it cannibalizes their long-term mind share. The 10-year-olds today who grow up using Chromebooks in school, Macbooks in college, and iPhones/Android phones in their daily lives, will end up investing in Google and Apple products as a working adult at home or at the office. The one remaining moat that Windows has over other operating systems is games and old software, but with Valve hard at work to get Steam games working on Linux, this last bastion of Microsoft's consumer presence is under attack as well.

More specifically, it's because Meta views the lack of ownership of their own hardware platform as an existential threat. They see AR/VR as the next revolutionary platform, so they're betting the farm on being first movers in a mass-market AR/VR space that they anticipate to exist in the future.

10000truths — Sat, 07 Mar 2026 15:27:03 +0000

None of these are rocket-science problems, they're just standardization issues. You build a library with your generate_id/serialize_id/deserialize_id functions that work with a wrapper type, and tell your devs to use that library. UUID libraries are exactly that, except backed by an RFC.

> The long-term outcome is Iran’s domestic drone production gets decimated.

That is impossible without committing to boots on the ground.

> Of course not. You blow up the factories and inventory.

Where are the factories? Where are the stockpiles? If they don't show up on satellite imagery, how do you find them? Boots on the ground. If they're hidden underground or beneath a mountain, how do you blow them up? Boots on the ground.

> No one has ever effected regime change with just air power. America could absolutely achieve a war aim with air power alone once Hegseth gets around to defining it.

The reason he hasn't gotten around to defining a war aim is that there is no legitimate war aim. Netanyahu wanted to blow shit up and the Pentagon foolishly followed along instead of telling him "you're on your own".
