Xenial seems to include nginx 1.9.15 and OpenSSL 1.0.2, so it should fully support HTTP/2. Personally I would still use the official upstream nginx packages.

IIRC, xenial beta1 included nginx 1.9.12 with http2 explicitly disabled.

Fortunately the support was enabled in the final release: https://bugs.launchpad.net/ubuntu/+source/nginx/+bug/1565043

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.

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.

This very much depends upon whether you want the latest OpenGL 4.x features or not. Compute shaders, etc. Most people won't notice, but if you want to develop or use applications using these features, the open drivers aren't yet up to par, so for these cases it is indeed a major downgrade.

I love the part about simplifying packaging via 'snap'. Now, I would love to know, if I'm a maintainer of Foo (and you can get it today via `apt-get install foo`), how will I be able to start packaging using snap rather than relying on deb packages that come from debian? I'd love any feedback, cheers!

> I love the part about simplifying packaging via 'snap'. Bleargh. More container bullshit, now with even less control over it by end users. Now each tiny library update (think OpenSSL security fixes) will pull hundreds of "snaps" instead of a single package… assuming the developers even realize they have to rebuild their snaps.

Something as core as OpenSSL should be provided by the system and updated by the system maintainers. That's what happens in Windows and OS X land, where the system provides a broad base of functionality that every application can count on (e.g. https://msdn.microsoft.com/en-us/library/windows/desktop/ff8...). Thus third party programs only need to bundle the elements not already provided by the system. When goto fail was discovered in the OS X crypto libraries, Apple simply issued a system update and that was the end of the story.

This reminds me, I'd really like to know what to expect with a 4K monitor in 16.04.

I've been running 16.04 beta for the past month on a Thinkpad P70 with a 4k display, and scaling has been great. The OS UI elements (like menu bars) can be scaled to any size. Most applications seem to work out of the box. The ones that have given me the most problems are a handful of desktop apps implemented in an embedded browser (like Spotify) where I have to set an extra command flag to properly scale.

That's great to hear, thanks. I'm using Xubuntu most of the time but I'll probably give it a shot and upgrade myself.

Say what you will about Canonical, their whimsical naming scheme has helped expand my vocabulary of both obscure African mammals and little-used adjectives.

17.10 might switch to flowers and "Apologetic Anemone" is a proposed name :-)

Anemone is also a sea animal.

I've been using an XPS 13 for 8 months as my main development machine and battery life hasn't been an issue. I regularly go out for a (e.g. coffee shop) working day and I don't have to charge. There were some issues with earlier Ubuntu/Linux/BIOS versions, but most have disappeared with new releases. The last one is a palm detection issue with the touchpad, but it should to be fixed in 16.04. And if you can't wait, a…

Are you using the sputnik "developer edition" or the standard retail version of the XPS 13?

The Sputnik version. That indeed reminds me I swapped the wifi card for an Intel one. Because they are better supported and it was cheap.

The original one was definitely working though.

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]…

You're conflating collision attacks like the Flame malware with a preimage attack that would be necessary to produce a malicious Ubuntu release with the same MD5SUM. I.e. what's "broken" about MD5 is if you have a lot of CPU time and I allow you to give me two unrelated blobs, you can craft those blobs to have the same MD5 sum. What's not "broken" (beyond a theoretical 2^123.4 attack) with MD5 and not broken at all f…

Collision attacks matter if you don't (want to) trust the Ubuntu release team.
