There was a recent presentation on this at EuroBSDCon for those interested.

Something like https://github.com/wheybags/glibc_version_header may be of interest to wean off using older OS’s in your build system.

Is it worth the effort to review until such implications are understood?

Wow that thread just kept going. Whilst the LWN article covered most of the "highlights" I think this reply from Theo is pretty suscient on the topic at large [1].

You may be interested in OpenBSD's pledge[1][2][3].

> Why trust a program to set its own capabilities?

An example may be that a program starts needing a wide range of capabilties but can then ratchet down to a reduced set once running, aka "privdrop".

> why isn't there a way to set capabilities from the parent process when execing?

There have been replies on other systems so just to stick with pledge which provides the abiliy to set "execpromises" to do this.

> Before rebasing, push your current work to your remote fork. This gives you a backup you can recover from if anything goes wrong

I don't follow this. Just abort the rebase?

The latest Oxide and Friends podcast episode is - as one may expect - a great pairing if you enjoyed reading this.

Don't parse the output of ls, use globbing or find. Here are some examples https://mywiki.wooledge.org/ParsingLs

Title truncated to fit within character limit.

Just to emphasize part of your comment as I think a lot a people aren't fully aware - Vim has an undo tree https://vimhelp.org/usr_32.txt.html#usr_32.txt

Dupe of https://news.ycombinator.com/item?id=38578247

Maybe I'm just of a different vintage but I'm just not a fan of these e-mail newsleters that seem to be the trend these days. I'd much rather follow a Github repo for this sort of thing.

I added the "(XNU inofleak)" to the title as I felt it was a bit too lacking in context without it. Hope that's OK.

It may be worth this submission being merged into https://news.ycombinator.com/item?id=38266773

Reminds me of similar post with some nice visualisations

Huh TIL Git can do this for non C-like languages out of the box. Is there a reason these custom hunk handlers are not defined by default for the languages Git ships support with?

Great now I can wait for this and Nantero! /s

I can’t say I’m overly fond of the writing style but thought this still had some interesting technical bits.

The general athesetic reminds me of the design concept "Mercury OS".

It's actually "Mathematical Double-Struck Capital X"

I had to truncate the title to fit within character limits, if a mod could expand this to the full "Half&Half: Demystifying Intel’s Directional Branch Predictors for Fast, Secure Partitioned Execution" that would be great thanks!

The paper can be found at the following link.

Wow that's a blast from the past! I'd totally forgetten about it, thanks for the link I'm goung to have to rewatch it for some laughs whilst I feel old.

Hi, I saw the Oxide Twitter account mention you’d be answering some questions from this thread on this evenings podcast so I hope this gets seen in time. Though firstly I should say congratulations!

Q: Are you shipping Milan racks and if so what does the moving to Genoa entail for Oxide?

Take some time out of your day and watch this presentation[1]. Regardless if you have any interest in the SR-71 or not.

I’m not a particularly sentimental person but hearing the following from Shul has stuck with me and feels like an appropriate reminder for today.

Yet another classic Cantrill talk nails this IMHO https://www.youtube.com/watch?v=MtrZJ4UqSn8
