Why Ubuntu's LTS releases are inferior to Red Hat Enterprise Linux

Filed under
Linux

It's time to update my view of Ubuntu with my most recent set of feelings. Well, with why I feel my most recent set of feelings, which is that Ubuntu LTS is significantly inferior to Red Hat Enterprise Linux.

Ubuntu's LTS releases (Ubuntu 6.06 and Ubuntu 8.04) promise five years of support (hence the 'Long Term Support' label). This support is why we're able to consider them, since we need more than 18 months of support that you get with regular Ubuntu releases; we're simply not in a position to update our servers that frequently.

(There are two reasons. First, moving operating systems in a production environment requires a fairly large amount of careful testing (and a certain amount of dealing with changes). Second, we run login servers and our users do not want to have to do migration work that frequently either; they have better things to do with their time, like complete their PhDs or do research.)

University students create award-winning open source projects

In my short time working for Clarkson University, I've realized what a huge impact this small university is making on the open source world. Our 4,300 student-strong science and technology-focused institution, located just south of the Canadian border in Potsdam, New York, hosts the Clarkson Open Source Institute (COSI), dedicated to promoting open source software and providing equipment and support for student projects. While many universities offer opportunities for students to get involved in open source projects, it's rare to have an entire institute dedicated to promoting open source development. COSI is part of Clarkson's Applied Computer Science Labs within the computer science department. It, along with the Internet Teaching Lab and the Virtual Reality Lab, is run by students (supported by faculty advisers), allowing them to gain experience in managing both facilities and projects while still undergraduates.

Linux 4.17-rc2

So rc2 is out, and things look fairly normal. The diff looks a bit unusual, with the tools subdirectory dominating, with 30%+ of the whole diff. Mostly perf and test scripts. But if you ignore that, the rest looks fairly usual. Arch updates (s390 and x86 dominate) and drivers (networking, gpu, HID, mmc, misc) are the bulk of it, with misc other changes all over (filesystems, core kernel, networking, docs). We've still got some known fallout from the merge window, but it shouldn't affect most normal configurations, so go out and test. Linus Read more Also: Upstream Linux support for new NXP i.MX8
