Are you happy with battery life? For laptops, I've always stuck with Apple machines but in my experience even Windows uses less power than Linux.

My laptops at least for the past 5 years have been fine with Ubuntu - much the same battery life as windows, and with a little tweaking quite a lot longer. I'm currently getting 7 hours out a commodity Asus with a couple of dev environments and a VM running. It drops to 5 if I'm running the fairly intensive service I'm developing, 4 if I do anything foolish like run the service from within eclipse, and 3 if I leave t…

> I'm currently getting 7 hours out a commodity Asus with a couple of dev environments and a VM running

Wow, that's very good. I've always found running a VW absolutely destroys battery life.

For laptops, I've only ever managed to get 9+ hours on a Macbook and that's pretty much the threshold that I'm comfortable with to leave with a laptop as my work machine for the day. If you're getting 7+ on your Asus running a VM, you have to be over 9 without the VM running, right?

I'm going to load 16.04 on my ThinkPad and see how it does.

Yes, there was a reason: Having to support other distros. The big deal now is that all the major distributions support the same mechanism.

Which of course still leaves OS X, *bsd, Solaris AFAIK. But it should cut down on the internal Linux incompatibilities a bit. I'm not a fan of systemd, but having one broken standard is much better than having four broken standards :-)

> Which of course still leaves OS X, bsd, Solaris AFAIK.

AFAIUI OS X has launchd, and Solaris has OMF[1]?

... so basically the BSDs are the ones left behind?

[1] I think that is the acronym for Solaris' XML-based standardized system service files? (I don't care that they're XML. It care that they're standardized.)

I never moved to mint, but I did recommend trying it to some people who really didn't like unity. I pretty much stopped doing that when they had the security issues last year. Is that what is prompting you to look at switching back, or are you just more reconciled to unity in general now?

If one wants Ubuntu and GNOME, there's

For anyone packaging software on Linux, this now means every major distro - Debian, RHEL/CentOS, Arch and now Ubuntu - supports .service files. No need for bash scripts, custom watchdog and daemonise tools, etc.

Upstart provided comparable service for years. There was no reason to use bash scripts and watchdogs / restarters before.

Except upstart actually allowed shell code in its configuration files[1]. Now, it did have the "exec" stanza which was far cleaner, but if you look through what Ubuntu actually did in practice, I think you'll find quite a lot of "script" stanzas in there.

I'm actually not sure the VM is making that much difference, which is surprising, although it's pretty much only running nginx, and having all the bare-metal virtualization stuff enabled has helped a lot with performance.

This is with core-M, so in many ways the things to watch out for are screen brightness and anything which makes the processors ramp over 800mhz - that actually seems more damaging than processes that just wake a lot

Another interesting tidbit, this version comes with

Cephfs v10.2.0 Jewel: "This major release of Ceph will be the foundation for the next long-term stable release. (...) This is the first release in which CephFS is declared stable and production ready!"

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.

Only temporarily. The closed source ones are legacy now, afaik. I believe AMD has said they want to only use open source drivers with closed source plugins; i.e. hybrid drivers.

Anyone know if it's going to be the same on Windows? Open source with proprietary plugins?

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.

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

Unless you've actually tested it with a shell other than bash, you should be marking it as bash. Otherwise it's likely it will not actually be portable between shells, and you will have made your software less reliable.

I've encountered many scripts written by developers on Fedora that totally fail over when run on Ubuntu specifically due to using #!/bin/sh when they really required #!/bin/bash.

Been using 16.04 on my XPS 13 for a week or so now, it finally supports nearly everything (bluetooth is a couple of extra commands) out of the box, and I've not had any issues so far.

how's the audio jack working, I got my XPS 15 last week, and planning to install ubuntu LTS once released. I read that audio jack is tricky to get working

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…

Why isn't just upgrading OpenSSL to version 1.0.2 enough? Seems easier than a wholesale OS upgrade.
