Favorite UNIX

by Kevin Bowling

What is your favorite UNIX. Three possible categories, choose one or more: 1) Free 2) Forced to use a commercial platform. I guess that could include macOS and z/OS with some vivid imagination, maybe even NT. 3) Historical Me: 1) FreeBSD - I find it to generally be the least annoying desktop and laptop experience with admittedly careful selection of hardware to ensure compatibility. It's ideal to me for commercial appliances and servers due to the license, tight coupling of kernel and base, … [View More]

Re: [TUHS] UNIX of choice these days?

by Norman Wilson

Warner Losh: It's an abundance of caution thing. This code had security problems in the past, we're not 100% sure that we've killed all the issues, though we believe we have. ==== And if there isn't anyone who's actively interested in the code, willing to dig in to clean it up and make security issues less likely, deal with multiprocessing matters, and so on, that's a perfectly reasonable stance. I think it's an unfortunate result, and I wonder how much of it comes from a cultural … [View More]

UNIX of choice these days?

by Arthur Krewat

What's your UNIX of choice to do normal "real" things these days? Home file server (NAS), business stuff, develop code, whatever. Mine is Solaris 11.3 at this point. Oracle has provided almost all the "normal" utilities that are used by Linux folk, and it runs on Intel hardware rather well. My main storage is a raidz2 of 24TB and I get 1.2GB/sec to a bunch of 3TB 512-byte-sector SAS drives. It serves my vmware farm with iSCSI at 10gbe using COMSTAR, which also houses a bunch of Solaris … [View More]

Re: [TUHS] [Groff] pic.ps

by Doug McIlroy

>> The Fedora system I have access to lacks /usr/share/doc/groff > Fedora defaults to loading only the package "groff-base" so that man pages can be displayed. To actually use groff for any other purpose, the packages "groff", "groff-doc", "groff-perl", and "groff-X11" have to be installed. Annoying, but there it is. That explains all. Thanks. doug

This sounds _exactly_ like a bad bug found in the RVD protocol (Remote Virtual Disk - a simple block device emulator). Disks kept suffering bit rot (damage to the inodes, IIRC). After much suffering, and pain trying to debug it (lots of disk writes, how do you … [View More]

Re: [TUHS] UNIX of choice these days?

by Norman Wilson

Larry McVoy: > +1 on what Ron said. I don't get the rationale for going back to ptrace. > Anyone know what it is? Is there a perf issue? Kurt H Maier: The usual rationale presented is that someone can exhaust the fd table and then you can't get anything done. Instead of fixing that problem, the popular approach is to add more syscalls, like with getrandom(2). ==== Funny that that rationale isn't extended to its logical conclusion: get rid of open and creat. Then nobody needs … [View More]

My MUA of choice, Alpine, certainly does, and it's hardly uncommon.
