I wonder which of my "pet" virtual machines will hit it first: slackware or voidlinux ?

Out of curiosity, what do you do with either of these "pet" machines? I always have an idea to make a virtual machine cluster, or something similar, but I haven't taken the plunge yet.

enriquto2• 6 years ago

I find them very useful for testing codes, as a sort of rapid-response travis. I run a script that pulls any new modification into each of my five "pets" (openbsd, slackware, freebsd, voidlinux+musl, dragonflybsd) and runs the tests. Since the systems are so different, it is very easy to break something. Since you notice it immediately (and not after waiting 1 minute for the travis answer) you develop a sense for avoiding non-portable things.

Slackware... they still active? No new stable builds in 4 years but seems to get security updates curiously. Their store leads to an error page in what looks like Chinese, confusingly.

The changelog seems to be, uhh, changing, so that's good I guess. I'm not sure they have many users left though.

Slackware still lives. I'm running it on my daily driver right now. I actually just started using Slackware a few months ago too, so it's gained at least one new user in the last 12 months.

Many updates are pushed to https://slackbuilds.org/ every week.

Things definitely seem to move slower than on other OSes, but I much prefer it that way. I still run a supported LTS kernel and a supported LTS Firefox release; as long as security updates keep coming I don't feel the need to upgrade to newer software by and large.

The store thing is a sad state of affairs. Basically, as I understand it, the store was not run by Patrick Volkerding but by a third party that agreed to share profits with him from sales of Slackware branded merchandise. Patrick states that after a few years and much review he was basically being ripped off by them and withdrew permission for them to continue.

Although helped by many volunteers Slackware is mostly a one man show and Patrick's income from the project was basically drawing down to zero. It seems to be a long, drawn out affair and I'm trying to come across as neutral here as I'm sure I don't have all the information. But I'll admit some bias as I started my life with Linux using Slackware from a CD that came with a book about Linux, I think in 1994, maybe early 1995. I switched to more mainstream distros at some point based on me using them at various jobs but always liked the idea of Slackware (the most BSD like Linux!).

And I'm posting this from a laptop running -current. Yes, 15 has been a long time coming but Patrick continues to publish updates and the Slackware Security mailing list is alive and active.

I'm off topic here so I'll wind this up with a note that the GCC package for Slackware Current is gcc-9.2.0-i586-4.txz. So I'm sure 9.3 will be coming along soon, though not as quickly as with some other distros.

For those interested in more about the store I found the most relevant information here[1] when I last went looking for a way to contribute money to the project (i.e. to Patrick).

Their both on 9.2 in their "current", rolling releases so I guess the race is on!

It landed in the Gentoo tree 12 hours ago :D

Are there changelogs for gcc point releases? gcc.gnu.org has a 'changes' link but it is actually a 8->9 changelog, rather than 9.2->9.3

not2b• 6 years ago

The ChangeLog file is in the source code distribution. But the point releases mainly have a large number of bug fixes, there are no new features.

garenp• 6 years ago

Yup. If you look at the end of the 'changes' link[1] you'll see individual bugzilla links for issues (or PRs as they call them) that were resolved in a given point release.

a lot of fortran fixes!

Honest question: what value does GCC have in 2020? It seems like llvm is the better designed compiler, more commercial support, more permissive license, etc. Pretty much everyone designing new languages today is using LLVM for backend codegen; and the people who aren't sure as hell are not using GCC.

alfalfasprout• 6 years ago

It's still the "de facto" compiler on most flavors of Linux and still tends to produce faster binaries in practice than Clang. That gap, however, continues to narrow.

CannoloBlahnik• 6 years ago

I always viewed Clang as faster, and perceived GCC as catching up.

mratsim2• 6 years ago

GCC is bad for anything related to big integer arithmetic or cryptography unfortunately. Something like 20 to 40% slower than Clang.

Example of GCC awful codegen on add with carry: https://gcc.godbolt.org/z/2h768y

gmfawcett• 6 years ago

GCC has the same value that LLVM had when it was first released: healthy competition for the market leader. The need to compete with LLVM was the best thing that ever happened to the GCC project. A world with only LLVM could easily lead back to a stagnant monoculture.

Therefore, it's in everyone's selfish interest to promote and use both toolchains.
