There's something mildly charming about fixes to ed(1) in software released today.

Fixed ed(1) to print bytes read/written and the ? prompt to stdout, not stderr.

hestefisk• 3 years ago

ed is still the standard editor.

VWWHFSfQ• 3 years ago

what do you mean by standard editor

cperciva• 3 years ago

And there's even a book about it, in case anyone has trouble figuring out how to use ed: https://www.tiltedwindmillpress.com/product/ed/

In the old days, Unix rescue boot floppy disk to fix workstations or servers only included minimal text editors such as ed (i think vi was added later). So if you were a Unix admin or power user, you need to know ed to fix the dam system. The 'ed' text editor was available everywhere. These days rescue disks boot from USB or CD/DVD-ROM and may have a full desktops or operating systems running. A little bit of history, I guess. BTW, I prefer https://www.system-rescue.org/ these days to fix Linux bare metals.

Perhaps more important, as a line editor, 'ed' would often work when your terminal was otherwise too borked up for vi or pico to work.

vbezhenar• 3 years ago

Last time I checked, OpenBSD installer didn't have any editors but ed.

Is there much that absolutely can’t be ran on OpenBSD without dropping into code? With its history of sane security it might offer some useful applications now.

"Modern" .NET is not compatible with it (or as Microsoft would say, "OpenBSD is not compatible with .NET"), and there doesn't seem to be much interest in resolving that. For comparison, it is available from official repositories at least on Ubuntu, Fedora, RHEL, and Arch Linux, and I use it daily to build and host stuff for $DAYJOB.

clort• 3 years ago

I don't know about .NET or OpenBSD specifically but Mono claims to be available on all BSD platforms -> https://www.mono-project.com/docs/about-mono/supported-platf...

daneel_w6• 3 years ago

Is there a huge difference between that and what Mono offers?

tester756• 3 years ago

As far as I've been there was some effort in .NET for BSD

Virtual machines for non-openbsd guests? That's the only thing blocking me to fully move to openbsd.

zokier• 3 years ago

Faq says that vmm supports Linux guests? https://www.openbsd.org/faq/faq16.html

I had issues with some Rust-backed python libraries, last time I tried to use it in anger.

Basically anything that is not C/C++ is a pain on non linux system...

seanw4444• 3 years ago

There seems to be a fairly low memory limit on processes, so when I tried to run a Minecraft server on my OpenBSD system, it complained about not having enough memory to start. Turns out the value seems to be hardcoded and compiled into the kernel. So... I'm not really sure how to run high-memory processes at this point, without self-compiling it in its entirety, which I don't really feel like doing.

t-34• 3 years ago

The limits are set in login.conf, it's not hardcoded.

xxpor• 3 years ago

It's relatively straight forward to recompile the kernel. Especially compared to Linux.

Most of the proprietary world, things like Mathematica and fast WiFi (they only support up through 802.11n, I believe), and the entirety of Steam. Things where for-profit companies make an effort to support Linux, but ignore smaller OS's. So it's a monastic experience compared to the modern Linux desktop.

(Monasteries are beautiful – still won't choose to live in one!)

t-34• 3 years ago

(they only support up through 802.11n, I believe)

Some newer wifi (iwx at least) work at higher speeds, but I believe this is mostly due to hardware functionality being moved to firmware. 802.11ac should be supported, but I haven't followed closely enough to know how well and in what drivers.

If you do a search the number one problem or concern for running OpenBSD is performance. And I dont think much has changed. I dont doubt there are certain domain where you would value security over everything.

kjs34• 3 years ago

OpenBSD had pretty poor support for SMP for quite a while, but lots of work has gone into fixing that in the last decade. That plus how much smaller the OpenBSD footprint is than, say, Linux, and you might find these days it performs pretty well.

citizen_friend2• 3 years ago

In this very release they give examples of many kernel APIs which are now unlocked.

LeoPanthera• 3 years ago

Hardware-wise, OpenBSD (deliberately) has no support for Bluetooth.

kelp• 3 years ago

Because their previous Bluetooth implementation was broken in various ways, and no one volunteered to fix it. So they just removed it.

j_not_j• 3 years ago

Every six months for the last 24 or 25 years (the web pages came after the early releases so a bit of uncertainty there. Explore for yourself at https://cvsweb.openbsd.org/www/)

And even vi gets fixes these days (Fixed handling of escaped backslashes in vi(1) ex_range).

Almost 28 years.

6.8 was released Oct 18, 2020. (OpenBSD's 25th anniversary)

gladiatr72• 3 years ago

Nice. I ran into an nvi bug years ago... if ":set numbers" and ":set noleftright" and then loaded a file of more than several kilobytes it would go into a malloc loop and segfault. We tracked it down and submitted a patch (this was to FreeBSD) and was told patches to src/contrib were not accepted (nvi was still "owned" by sleepycat). Good to know that at a certain point, function can overtake form!

MobiusHorizons• 3 years ago

Exciting to see some initial work to support the rk3588 soc. It has a lot of potential for use as a NAS or router or home server.

neodypsis• 3 years ago

Could it support the PinePhone?

Panino• 3 years ago

Not yet, but see this:

Probably [1], but it certainly needs more hands on deck last time I talked to Crystal.

About to upgrade my amd64 system.

I already upgraded my very old i386 (R51e), no issues and very easy. I am getting some mystery core dumps, will look at that later. I suspect the new "Permissions (RWX, MAP_STACK, etc.) on address space regions". but only guessing :) On the i386 I am planning on using a new "old" disk since the old disk is getting tight. Then I will worry about the dumps after an install.

edit: Fully updated to 7.3 on amd64, no issues all working perfect. Again easy no no manual configs for me.

unethical_ban• 3 years ago

When I was in college I followed FreeBSD and Solaris for a bit just to dabble outside Ubuntu and Fedora.

I remember looking for info on FreeBSD versions and wondering what the heck RELENG was.

I've always found building/running your app code on OpenBSD (even if it's not your target OS) - makes for a better app overall because of how strict OpenBSD is - it forces your app to run "correctly" more than any other OS.

I've been able to find and fix way more app bugs, than when I ran my software on other OS'es

darknavi• 3 years ago

Any specific examples? I don't daily drive Linux but that sounds interesting.

Somewhat related, for Minecraft (Bedrock, C++) we compile with a ton of different tool chains and I really appreciate Clang versus MSVC for how strict the compiler can be (even with /-permissive).

Ted Unangst’s “Developing Software in a Hostile Environment” talk from EuroBSDcon 2019 is a good start. Controlling malloc(3) behaviour with malloc.conf to catch initialisation and Use After Free bugs is a great example from there.

Personally, a different userland and directory structure usually also beats out Linux-isms.

synack• 3 years ago

I wish I could run OpenBSD on the arm64 EC2 instances. Last I checked, there's no driver for Amazon's ENA network interface.

pedrow• 3 years ago

I have an OpenBSD install in a VM for the reason cited by ninjin:

Personally, a different userland and directory structure usually also beats out Linux-isms.

I just upgraded from 7.2 with sysupgrade then pkg_add -u and it worked perfectly without any intervention from me. In the past I remember it needing a bit of tweaking and finger-crossing. Bravo OpenBSD!
