mighty-snitch VS linux

6 months in to my first pc build. had one other pc for past 2 years from letsbld.

the build is easy, but it will take a full day. it is also a bit nerve racking, but mostly that’s just inexperience. parts are all sturdy and snap together. i will be building every nvidia generation from now on.

i used to code on laptops, then game on a pc. now i have to ssds, one windows one linux. bios boot option is unborkable. it’s a great setup.

it’s nice to be able to play fortnite, compile the linux kernel[1], and do gamedev[2] all in a single session.

be aware ddr5 amd boards boot kind of slow. i’ve heard intel is faster.

if you can afford it, go god spec. otherwise spec down into your price range. letsbld and originpc have good configurators to choose parts. newegg prices will be 30% less.

check out fractal torrent cases and dh15 coolers! 4090 fe fits in the nano and 4090 pny fits in the compact.

learning cloud is not necessarily using cloud for all things.

cloud adds legitimate new capabilities to every engineer.

if i’m on coffeeshop wifi with my low power laptop, and i need to do something intense like compile linux, i’m sol.

unless i know aws. then i can open a new terminal, spin up a massive spot instance for 19.27 minutes, get that done, then self destruct. [1]

being able to test lambda to s3 io, or ec2 to s3 io, with the same ease one uses grep and sed, is for great good. also it’s fun.

you jest, but this is actually fine.

do this via mighty-snitch[1] on any postmarketos phone. any network request passing through the linux kernel gets filtered.

still hosed if it’s hardware level nonsense unfortunately.

the only reason i’m not daily driving postmarketos if lack of gpu acceleration for firefox. hopefully soon!

i just built 6.2 for arm64. what timing!

use a network snitch[1] on desktop and mobile. The original slogan says it all: makes the invisible visible. i’d love to use a disk snitch too, but no exist yet afaik.

it’s interesting to see firefox or any other legitimate app i’m using make many unsolicited requests to weird domains. it feels good to interactively deny those connections.

make sure that cloud[2], which includes git hosts[3], are untrusted. unencrypted data should never hit remote. keys should never leave local.

consider the tradeoffs with online interactions. engaging with other humans in public on github and hackernews is likely worth. engaging in impassioned op-ed debate with bots on engagement monetization platforms like twitter or youtube is likely not.

FFS predates FreeBSD and is in some capacity supported by all 3 major BSDs. I'm fairly confident that Linux actually supports it through the ufs driver ( https://github.com/torvalds/linux/tree/master/fs/ufs ); whether the use of different names in different places makes it better or worse is an exercise for the reader.

These are a bit easier to see what's going on:

Unfortunately Github doesn't have a way to render symbols for whitespace, but you can tell by selecting the spaces that the previous version had leading tabs. Linus changed it so that the tokens `default` and the number e.g. `12` are also separated by a tab. This is tricky, because the token "default" is seven characters, it will always give this added tab a width of 1 char which makes it always layout the same as if it were a space no matter if you use tab widths of 1, 2, 4, or 8.

There was also a Gentoo effort to run atop FreeBSD[0]. The challenge of course is that afaik none of the BSD kernel ABIs are considered stable. The stable interface is the BSD libc. That said, with binfmt_misc, I don't see a reason you couldn't just run (at least some) FreeBSD binaries on Linux with a thin syscall translation layer (rather something like qemu-system) and then your layer hooked via binfmt_misc. I'm not aware of anyone who has done this for FreeBSD, but prior efforts existed as alternate binfmts for SysVr4/5 ELF binaries[2]. Either way would take some elbow grease, but you *might* even be able just reuse binfmt_elf and just have a new interpreter for FreeBSD elf.

> The original less-than check was deemed incorrect

It was only deemed incorrect because of an information leak. Not because it's a valid use-case for user space to copy smaller portions of *hwrpb into user space. https://github.com/torvalds/linux/commit/21c5977a836e399fc71...

Correct. And the combined work needs to carry the MIT license text and copyright attributions for the MIT software authors. With binary distribution it must also be overt, not hidden in some source code drop, but directly accompanying the binary.

Many people who talk about relicensing never credit the MIT developers or distribute the MIT license text. "Because it's GPL now."

I don't think that you believe that, but many developers do.

Some don't see the need for source code scans for Open Source compliance, because the license.txt says GPL, so it's GPL. Prime example is the Linux kernel. There is code under different licenses in there, but people don't even read https://github.com/torvalds/linux/blob/master/COPYING till the end ("In addition, other licenses may also apply.") and conclude it's simply GPL 2 and nothing else.

Also be aware that sublicensing is not the same as relicensing.

He notoriously hates GNU Emacs, yes.
