That all sounds exhausting (introvert here).

The last thing I want to do when out in public is be stuck talking with strangers.

Huh, I just ran the same timing command for my fish shell (with starship prompt) and got 168ms.

What all is happening in the Zsh profile?

If you don’t owe then you have 3yrs (IIRC) to file.

Of course, you also don’t get a refund until you file.

And you usually have to do all the same work to know whether you owe or not…

Just wait until you _don't_ buy something...

Throw some items in your cart and enjoy all the emails reminding you to check out, look at similar items, share with your friends, and use discounts before they expire!

> A neat trick I was told is to always have sleep statements in your code. Just a few sleep statements that you can delete in cases like this. This won't fix the problem, but will buy you time and free up latency for stuff like slow algorithms so you can get faster code.

FTFY ;)

New comment by jasonpeacock in "Improving my focus by giving up my big monitor"

My viewing distance is one-arm-length (kinda close), when I raise my arm my fingertips just touch the screen. Definitely closer than my previous monitor, as you need to sit within the curved-screen radius to be in the sweet spot.

Looks like it's 32:9 aspect ratio - it's this Samsung, it was on sale last week for $800: https://a.co/d/0f884LPO

I just upgraded to a 49" curved display because it lets me view everything I need _for the current task_ at one time.

One virtual desktop is Messages, Slack, and Outlook for all my comms needs.

Another is IDE & browser for development work.

Another is todo list, planner, notes, and browser for task management.

Having to constantly swap app between browser, email, IDE, slack, etc is interruptive. Being able to switch to a single-focus desktop with everything visible is much more productive for me and reduces context switching.

My guess is that it's for drop-in compatibility with make.

There is (at least) one open issue about this - the solution/alternatives are not trivial:

Long ago, I bought the O'Reilly "Sed & Awk" book with plans to become a true unix guru.

Then I realized I already knew Perl (and Perl one-liners), so there it sat unused on the shelf.

I'm concerned that someone had the permissions to make such a change without the knowledge of how to make the change.

And there was no test environment to validate the change before it was made.

Multiple process & mechanism failures, regardless of where the bad advice came from.

Flakes fixes this for Nix, it ensures builds are truly reproducible by capturing all the inputs (or blocking them).

You can network-jail your builds to prevent pulling from external repos and force the build environment to define/capture its inputs.

jasonpeacock — Tue, 24 Feb 2026 21:58:57 +0000

I’m curious why they didn’t deploy diagnostics in the field if they couldn’t replicate in the lab?

Every few months for 7yrs is a lot of opportunities to iterate on collecting field measurements. And it could be done in a holistic way that doesn’t break the safety certification.

I’ve always that forums are much better suited to corporate communications than email or chat.

Organized by topics, must be threaded, and default to asynchronous communications. You can still opt in to notifications, and history is well organized and preserved.

The bullet points for using Slack basically describe email (and distribution lists).

It’s funny how we get an instant messaging platform and derive best practices that try to emulate a previous technology.

Btw, email is pretty instant.

New comment by jasonpeacock in "A header-only C vector database library"

jasonpeacock — Sat, 14 Feb 2026 21:27:00 +0000

C libraries have advertised "header-only" for a long time, it's because there is no package manager/dependency management so you're literally copying all your dependencies into your project.

This is also why everyone implements their own (buggy) linked-list implementations, etc.

And header-only is more efficient to include and build with than header+source.
