Making rent as an open source developer.

This is not usenet, it's the openbsd misc@ mailing list.

No.

Perhaps relevant, Students from the University of Southern Denmark released a paper earlier this month, which once again noted the fact that over ~90% of the OpenBSD base system uses pledge(2). Almost certainly all of the network speaking daemons in base do.

I'm pretty sure a MIPS doesn't have them on port 60h/64h, or indeed any I/O ports.

Funnily enough, it does. They're just sitting behind a AMD CS5536 PCI-to-ISA bridge.

Other machines, such as the DEC Alpha were similar.

Also in addition to funding the open source projects you use, if you can, please consider directly supporting individual contributors/developers personally who work on those projects, many are volunteers and even a small monthly contribution could mean the difference.

Defending open source should begin with real, tangible support for both the projects and its developers. Not just words.

With my OpenBSD developer hat on, getting new hardware in the hands of developers is really important, many of us are hacking on 5-10 year old thinkpads that need replacing.

If you're interested, you should check out Miod Vallat's Motorola 88k story.

http://miod.online.fr/software/openbsd/stories/m88k.html

One interesting bit of trivial is Luna-88k workstations were heavily used to implement CMU Mach (which would eventually be used by Apple).

I don't see any "gibberish".

The artwork on the store may have been an earlier (non-final) version, or there's just simply multiple variations, which is usually the case for the t-shirt art.

Job Snijders works closely with the artists each release, and runs the store.

OpenBSD supports sparc very well and is compatible with old sunos stuff (iirc)

No 32-bit sparc anymore (only UltraSPARC, aka sparc64).

No SunOS compatibility (despite Theo de Raadt inventing it for NetBSD, before being copied by other BSDs).

Technically there's a niche flavour of 68k that still is supported because of a very dedicated man in Japan

luna88k, while related, is not 68k.

Shameless low-volume rss feed drop.

Also the embedded mastodon feed on my site uses rss.

I haven't, honestly the application processes, paperwork, project reporting expectations and eligibility criteria for these kind of funds just gives me too much anxiety. I never know how to navigate it as a Canadian either, most of them are US or Europe based.

I guess I'm naive to hold out for the anonymous bitcoin millionaires to donate "no strings" until I find something a bit more frictionless.

Thanks anyway for the suggestion, glad to hear you're getting sponsored for your FreeBSD work.

Trying something different again here, sorry.

Location: Canada

Remote: Yes

Technologies: C, OpenBSD

I'm looking for monthly/yearly "no-strings" sponsors, not employment, if any individuals, companies (or bitcoin millionaires) would like to help a long-time OpenBSD slacker, unslack, I'd really like to focus more of my time on open source development (and advocacy), rather than making rent. Feel free to contact me (see HN bio).

GotHub is pretty cool, it's from the developers of the Game of Trees project, but git compatible.

.. macOS only ever programs CS42L84 to operate at either 48 or 96 kHz, we could only add support for those two sample rates to the Linux driver ..

However, CS42L42 supports all the other common sample rates, and while the register layout and programming sequence is different, the actual values programmed in for 48 and 96 kHz are the same across both chips. What would happen if we simply took the values for all other sample rates from the CS42L42 datasheet and added those to the CS42L84 driver? As it turns out, you get support for those sample rates!

The patch to enable hardware support for 44.1, 88.2, 176.4 and 192 kHz sample rates on both the input and output of the headphone jack was submitted directly upstream, and has been merged for 7.1. We also backported this to Asahi kernel 6.19.9, allowing users to take advantage of this immediately.

Nice bit of chip sleuthing and reverse engineering from the Asahi team!

EDIT: Article seems to have been updated to remove mention of Chromium.

It's very difficult to reason about, for instance compare the OpenSSH sshd sandbox implementations.

w/ Capsicum, beyond faffing around with some file descriptors, it's unclear what security cap_enter() adds:

https://github.com/openssh/openssh-portable/blob/master/sand...

EDIT: Article seems to have been updated to remove mention of Chromium.

This article contains a lot of errors, for example Chromium on FreeBSD does NOT use Capsicum, it never has. That was experimental and invasive work done 17 years ago that was NEVER committed to their official ports repository. In fact, not a single browser on FreeBSD uses Capsicum or any form of sandboxing _at all_.

https://github.com/rwatson/chromium-capsicum

https://www.freshports.org/www/chromium/

https://cgit.freebsd.org/ports/log/www/chromium/Makefile?qt=...

Contrast that with OpenBSD, where the Chromium port has used pledge(2) since January 2016, and unveil(2) since 2018. Both are enabled by default. Mozilla Firefox ports also use both pledge and unveil since 2018-2019, with refinements over the years.

OpenBSD's fork of tcpdump has been privsep for ~22 years, and its packet parser runs with no privileges. It's pledged tightly "stdio" and has no network/filesystem access, and uses OpenBSD specific innovations like bpf descriptor locking (BIOCLOCK) missing from both FreeBSD/Linux tcpdump today (despite FreeBSD adding the ioctl in 2005).

In the years since it was added, the reason Capsicum has only been applied to a handful of utilities is because it's a tree barren of decades worth of incremental work on privilege separation and security research.

I didn't say Loogson the company was dead, or that LoongArch was either. I said the predecessor Loongson/Godson CPUs are, like the 2E and 2F, which were MIPS-compatible. They're not manufactured anymore, and were practically unobtainium when they were.

LoongArch is not MIPS, despite it having similarities. It's a new platform/ISA and requires a completely different toolchain and new OS port.

It is not at all "new MIPS-family hardware is being made today" like you originally wrote, and it has little to no relevance to SGI hardware.

AFAIK Loongson is dead and isn't made anymore, and unlike OpenBSD/sgi, Loongson was a little-endian arch. OpenBSD/octeon is a closer match, but also discontinued as Cavium switched to making ARM CPUs.

LoongArch is a new ISA and isn't MIPS compatible, and OpenBSD doesn't support it.
