Linux A new version of the real-time Linux scheduler called SCHED_DEADLINE has been released on the Linux Kernel Mailing List. For people who missed previous submissions, it consists of a new deadline-based CPU scheduler for the Linux kernel with bandwidth isolation (resource reservation) capabilities. It supports global/clustered multiprocessor scheduling through dynamic task migrations. This new version takes into account previous comments/suggestions and is aligned to the latest mainline kernel. A video about SCHED_DEADLINE is also available on YouTube.

You`ve been on osnews too long. "Perhaps linux is.." Actually if you have had all three mainstream OS`s installed, say windows XP (which can be made to run quite smooth), OSX (actually slow, sometimes even taking 5s for keyboard response here) and for instance Ubuntu (many would call it a bloated linux, but still), you would actually prefer Ubuntu. So how can linux be badly written? Indeed it seems to be the better of them all. If you wanna talk about badly written, think about the product MS sells. That is all, no enthusiasm, just a dollarmonkey, a product sold, just as cp/m once was. Also junk. I think most enthusiasts agree that windows is POORLY written. And OSX shows that even original unix code, can turn to a windows-like annoyance. Linux though, and Ubuntu, lots of choice. Modular mindset. And the best of code. You wanna run a windowmanager from the time of pre-overobfuscated high-level concepts, try IceWM, with a good theme. And you don`t have to worry about all the desktop-soapopera either. "no desktop id dead" "no desktop is alive" "no linus killed the desktop with evil mentalrays". And here I was running IceWM and not noticing a thing. And Wayland is coming in a big way.

"Poorly written" - no. And it has a lot of innovation, and seems to be incorporating more and more of realtime aswell. Have you ever played an openGL game with ACCURATE fps? It is just so much more enjoyable. Not to speak of how lowlatency/lowjitter improves the responsiveness of the desktop, making activity already on the next frame, after input.

No "lie", no evil coders. But as many places linux has been associated with several things. And for instance something many people "know" is that Gentoo is for "performance". However it`s mostly a myth, and in their forums you will get some really bizarre answers from time to time.

What I suggests is really just trying out the most popular distributions like Ubuntu/Suse/etc.

If you`re into realtime, or low-jitter, you might want to build yourself a PC just for that purpose also.

I am doing one, and it looks like this currently: http://paradoxuncreated.com/Blog/wordpress/?p=4176

It`s gonna be great.

Peace Be With You.

I'm a quite able Linux user and I have to fiddle around with Windows XP/7 on a regular basis while I personally use OS X.

Sadly I have reached a stage in my life where I don't have the time or motivation to check out Linux distributions, testdrive different GUIs or build my own PC. There was a time when I did this and I'm happy it's over.

Linux desktops are fast, even heavy ones like KDE, but my gripe is with the application software. IMO it's just not good, certainly when compared to Windows and OS X counterparts. There is some good software, but in few numbers.

When I use Linux I prefer CLI only. That's fun to use and all the CLI commands and programs are very useful, powerful and just work.

For the usual stuff that a typical user likely needs, the software is fine I'd say. Browsers, Open/Libre Office, bittorrent clients, image viewers/organisers are perfectly OK, plus throw in some media player and IM - those last two tend to be somewhat better actually: multi-communicators and plays-everything seem to be more the rule on Linux than on Windows & OSX.

(sorry for a late reply, again ...I think I went to sleep when I had this reply window opened ;) )
