From some sources, I've heard that it appears that those with AMD graphics will suffer a downgrade in performance until the point release in June. I think by June, the open source AMD drivers should be up to speed or have the same features as the previous flgrx ones. From what I gather it's more like a downgrade in supported features. I think this is just an issue if you are doing 3D graphics work or gaming.

Could you, please, explain what .service files are and how they eliminate the need for bash scripts etc? Couldn't find anything in search results.

systemd services, that replace traditional init.d scripts and provide watchdog options, daemonising, etc. https://www.freedesktop.org/software/systemd/man/systemd.ser...

PSA: If you're running a HTTP/2 server like NGINX on the 14.04 LTS you'll want to upgrade to this release. Google Chrome will no longer support HTTP/2 on vanilla 14.04 after May 15th [0], even if you're using the latest official upstream NGINX packages. This is because 14.04 ships with a version of OpenSSL that does not support the ALPN extension (prior to OpenSSL 1.0.2 you're limited to NPN, now deprecated). There w…

Is http2 supported on xenial now? It wasn't as of beta1 -- http2 was considered 'experimental' and wasn't included in the builds. We're using the PPA instead.

My understanding is that HTTP2 support in Apache was held out of Xenial but may be included later.[0] nginx in Xenial does have HTTP/2 support but no SPDY.

It looks like Ubuntu 16.04 comes with Nginx 1.9.15, which is both not the latest stable release (it's a development, aka MAINLINE, release, although Nginx development branch is pretty stable) and it's one minor version ahead of Nginx's own development PPA, which is at 1.9.14.

The ppa[1] notes there's a newer version[2] also

Most people with AMD graphics have been using the open source drivers and will just see all around improvements.

edit: Also, you can get Vulkan with the new drivers.

You're getting downvoted to oblivion, but I'm old enough to remember not being able to take bash for granted. The default shell on some modern systems (OpenBSD for example) comes to mind as well. I feel this battle has mostly been lost, however.

Default on debian is dash.

But bash is installed by default if I'm not terribly mistaken, and it's classified as an essential package. If you put in a bash shebang, it should work.

HN coolkids downvoting advice that makes software more portable and reliable. What a fucking shock.

They use bash as a service. It's integrated in node.js 2041.4.1.

A little more verbosity on the advice might have helped. I wouldn't have properly understood you were saying without @peatmoss's reply. So without the context, your original comment just seemed like knee-jerk bash-bashing.

They should just stop publishing MD5SUMS for new releases. By now, everybody should have gotten the word that MD5 has been broken. The security of the MD5 has been severely compromised, with its weaknesses having been exploited in the field, most infamously by the Flame malware in 2012. The CMU Software Engineering Institute considers MD5 essentially "cryptographically broken and unsuitable for further use". [1] [1]…

i thought the use of md5 here was just to check that your download wasn't damaged, by comparing your hash to theirs.

The purpose of publishing a public MD5 sum of a software release from the developer is to prevent tampering with an image. If I download an ISO of Ubuntu and check the MD5 value, and it doesn't match what Canonical says it should, then it's been tampered with.
