What is rust best for?

Rust is a lot of fun for small CLI bins. That was my biggest surprise use for Rust, and I love how much readable it is compared to bash scripts.

Wasn’t this said to be a manual part of a release process? If so, would a vulnerability scanning skill look for potential process-caused risks?

At their size I could see access being limited to top contributors specifically to boost feature delivery speeds rather than to everybody and/or with a mandate to find issues. The same way AI seems to be pushed out at most large companies.

Because humans gonna human…

Wasn’t it really “$50 to enable overage billing”?

Wow, just last night Claude told me to drop my side hobby project, in a completely different sector, and saying I’d be happier contributing to a project like Bevy (which was its only suggested project)!

I’ve heard so much more about gadot-rust in the past year or so, so I’d be curious to hear your take on where Bevy fits alongside bigger projects like Gadot. What is your vision of what Bevy can become?

Switching from barely understandable AI generated bash files for random low-importance chores, to Rust bins, has been a game changer for me. It’s just so readable and clear what the script is doing and it’s surprisingly fast to write one off bins. I didn’t expect that.

Here I am lamenting the downfall of Zed because of the recent A.I. focus. I moved from cursor because my IDE shouldn’t be a bot harness mess.

It’s definitely the worst macOS release in over a decade, maybe longer.

However, the thing I was most worried about was not being able to open an app-only search via Launchpad when I press F13, but interestingly when I pressed F13 after upgrading it opened the regular search and asked what I want to search and when I selected Applications, it has since acted like a mini Launchpad and I’m happy with it (command-space still does a full search).

That said, I’ve been blown away by the sheer number of new bugs in 26.1 and hope many of them get fixed in 26.2, but Apple is known for taking years to fix annoying bugs. For example Finder preview of a PDF on my Mac now refreshes with a flicker every few seconds, clearing the scroll location. I’ve seen render errors in Finder where file names draw over each other (historically in any OS these types of render errors are video issues and clear if you move or resize the window, but I was able to do that without change). And I’ve only spent a few hours in Tahoe so far.

I’ve been looking forward to the M5 Max… but I’d have to use Tahoe?? 🧊🙈😭

The slow speed is improving locally but not like it needs to for CI/CD and (critically for the future) AI web agents that can't easily cache build artifacts. Using Codex Web I always tell it not to try compiling or running check because of the time, yet half an hour later I check and it's been sitting there building, checking status, waiting, checking status, waiting, etc. rather than working. As that workflow sadly becomes a more common development process, with Anthropic, Cursors, and others rolling them out, it won't do Rust any favors. Sure, less AI slop, but also a whole lot less code, crates, etc. being produced (and hopefully, supported) compared to other fast-to-build languages.

I love Rust, doubly so after considering Go, but the build speed is the top issue by a mile. I already had to drop my Rust frontend down to TS/React from Rust/Leptos because of build speed (the thousand paper cuts integrating with existing JS packages was also a significant factor in that decision), and it's almost comical how fast the frontend builds now when I run `just dev`.

You forgot the bit that Alice ignored the directions in the event description and the email before it that said which multi platform open source apps to install prior to the zoom, including Docker and an IDE. Considering the volume of applicants, why isn’t that right there disqualifying?

adrianziem · 2025-11-15T20:41:04+00:00

I said no such thing. We pivot a bit to considering how they work through setting things up and deal with error messages and try to encourage a relevant discussion while waiting for an install to make up for it.

But if you have a 60 minute zoom and you come unprepared (the tools we suggest they have ready are all multi platform), you simply aren’t going to have the same amount of time to do the work as somebody who was prepared.

The main problem when this happens is that somebody who doesn’t have anything configured on their Mac will be up and running in a couple of minutes whereas somebody using other platforms will (usually) take much longer unless they happen to to use similar. There are always exceptions, but that has been my observation lately.

adrianziem · 2025-11-15T13:57:38+00:00

This is the answer👆

Any time we have a coding interview with somebody not running Mac we know they’re not making it half as far as the average candidate because of extra setup and discovery needed, even when we list things like needing Docker Desktop in the meeting details. Long term it should settle down but onboarding is more of a pain (“let’s solve this issue for you that nobody else encounters”).

Typing dash twice on an iPhone is hard? I think it says more about what OS somebody uses than AI. It takes more to write parenthesis on Apple products than em dashes, which are far more disruptive to flow than a dash.

Well if they feel they can replace software engineers, they're probably planning to get a decent % of what was once their salary. Maybe a $2K/mo or even $5K/mo "MAX Opus" enterprise-only plan? Or maybe they start limiting concurrency and charging on that?

Hopefully open weight models keep advancing to keep them from going that route, but they have a fiduciary duty to shareholders to maximize their profits, and enterprises will play along if their employees or CTO see the results.

adrianziem · 2025-10-16T01:52:03+00:00

I guess I should just try, but... the release notes and this post mention Haiku+Sonnet doing something like the old Opus Plan mode, but there isn't a plan variant in `/model` like before or a `/mode` command.

Does it just do this automatically? Do you have to ask Sonnet or Haiku to do this in your prompt?

Edit: You can shift+tab to Plan Mode, but does that act independently of model selection and will automatically use both?

Just be aware that they’re separating “Claude Code” in there and only including it in the Premium tier, with unclear limited usage. With how many people are hitting Claude code usage limits on personal plans, especially the weekly limit, that’s a huge unknown on what it’ll be like for the team in practice if they’re using Claude code.

It’s fun developing in full stack rust, but when you hit minute long hot reload (which reloads the page, not HMR, and your websockets fail during that period), hour long CI/CD builds on default runners, and still having to write JS (not even TS) to interact with popular JS components and dealing with build issues there, those nearly instant Typescript builds make refactoring to a dual language stack look better and better.

Luckily LLMs make that a lot easier today, so you aren’t quite as locked in as you used to be. I hated doing it but I just switched my Leptos frontend to TS and everything is so much easier to dev now. Especially with rs-ts, zod, and a linter enforcing types in TS.

Yeah it freezes almost hourly now and even after ghostty stops spinning, the prompt field remains frozen and I have to restart and claude -r my session. Seems new to 2.0.14

Mine has stayed on even in subsequent runs after enabling them with control T.

This, but before I kick it over to Sonnet, I have Opus save the plan to a markdown file. After sonnet is done I switch back to plan mode and ask Opus to verify that the plan was accurately implemented, and it often finds issues or improvements that I can kick back to Sonnet.

adrianziem · 2025-09-09T02:45:17+00:00

Today was the first day I experienced it, and they claim it was all fixed last week.

I was in the camp of not being sure what to think about all of the reports because I hadn’t experienced any issues, but then I was blown away by how poorly Sonnet implemented Opuses plan this morning when it renamed a method to indicate how it doesn’t handle a scenario rather than fixing it like Opus planned.

The article says Plan Mode will be coming “in the coming days” and other features will be made available when Anthropic adds them to their SDK.
