Is there a command-line tool that takes arbitrary UTF-8 text and formats it into 72 characters per line with linebreaks set properly and two spaces after a period? :BoostOK:

Alternatively, I might write my own one by creating a small lexer.

Are there any recent epoll(2) vs. fork(2) benchmarks for TCP servers? Most of what I can find is from the early 2000s, but a lot has changed since then, including a new scheduler. :BoostOK:

@feld Maybe not a scheduler issue, but was COW during fork(2) a thing 20 years ago?

engler,
@engler@chaos.social avatar

@feld I believe COW improves the performance because it should save the time lost during the memory copy.

And no, I certainly want to use processes instead of threads because they offer a more fine-grained control over permissions, such as with technologies like seccomp(2) and pledge(2).

@Uni_Stuttgart please stop blocking UDP traffic in your eduroam, it’s required for QUIC and WebRTC and generally makes your network a pain to use with anything except old-style web browsing.

@filmroellchen @Uni_Stuttgart Have you considered running a WireGuard service at port 53/UDP? Having an intense conversation with your DNS server is a pro gamer move in order to circumvent UDP blockage.

Advantages of bicycles:

  • No need to worry about fuel or gasoline prices

  • No need to worry about car insurances and general inspections

  • No need to worry about finding a parking lot, you can park it almost everywhere

  • Even if it gets stolen, you can simply get another one without much financial damage

  • Repairing it does not require you to be a mechanic

  • It keeps you fit and healthy

Why do people love their cars so much?

A street cat came to me today in order to get patted by curling around my leg. Today was a good day.

The urge to submit a talk about a toy project started a week ago in the last minute and hoping to still have interest in it when the event takes place.

@fallenvalkyrie As someone who almost exclusively writes libraries or very low-level C components, I can tell you that a missing front-end never makes something entirely useless. 🙂

@fallenvalkyrie As someone who contributed several patches to curl, usage of this tool never gets old for me. :)

My handwritten signature should be a valid Ed25519 signature computed in my head.

to my understanding doas is always the better choice over sudo

unless u use the special features sudo provides. like it is more powerful but also has huge security holes every few years

engler,
@engler@chaos.social avatar

@grillchen Even better: Do not use such a tool at all.

Using the root account manually made me much more careful in executing commands as root.
