Linux 3.5 Released
diegocg writes "Linux 3.5 has been released. New features include support for metadata checksums in Ext4, userspace probes for performance profiling with systemtap/perf, a simple sandboxing mechanism that can filter syscalls, a new network queue management algorithm designed to fight bufferbloat, support for checkpointing and restoring TCP connections, support for TCP Early Retransmit (RFC 5827), support for android-style opportunistic suspend, btrfs I/O failure statistics, and SCSI over Firewire and USB. Here's the full changelog."
It's funny. The Linux community put so much effort into trying to win the OS of the Desktop with so little success, but secretly won the battle of the OS on phones and tablets with hardly a fanboy.
Now this looks interesting. Hopefully it works as described on the net (http://lwn.net/Articles/479841/). Automatic suspend would be wonderful.
even though i'm logged in, kernelnewbies page says "Immutable Page" - so maybe somebody with write privs can fix "makes impossibles" ;)

Ext4 metadata checksums. I like that. Note that it isn't data CRC checksums, just metadata. Still, I like the way Ext4 keeps evolving and getting tuned. Btrfs sounds really great, but it may still be some time before it is stable enough for my data storage needs.
Does this feature work transparently and automatically, or does one need to enable it?
the politics of old school Unix hackers. It is the kind of politics that keeps distros from really standardizing on a GUI, and also results in oddities like the Linux Foundation having an SDK for mobile, but none for desktop. Likewise, Android has an SDK but Ubuntu (and all the other desktop distros) do not.
Anyone knowledgeable can tell me what is "checkpointing and restoring TCP connections"?
A GNU/Linux kernel that is libre, there's a redundancy if I ever heard one. Like Sun Solar company.
So, is this thing finally usable in production or is everybody who actually cares about data still stuck with ZFS?
I'm impressed... no really (even though I am a known "Windows fanboy" around here): I've tried KUbuntu 12.04 recently, & am impressed, but moreso w/ the Linux kernel circa 3.3 onwards (no known security issues I am aware of at least - not even LOCALLY exploitable ones, & that's pretty damned good, unless others here can show me otherwise to correct me with more current information...).
* Thus, I only expect Linux to continue to excel based on that foundation...
APK
P.S.=> I've said it here before here on /., & I might as well again now too:
Linux is proof that the people of the world CAN & do work well together to produce something pretty cool of their own freely given time & effort... without having the "taskmaster's whip" applied to their back (in other words, for work alone to support their families but not really because it'd be what they'd want to do or be doing possibly - just a means to the ultimate end, supporting you & yours).
Linux = what I call a "socio-technological phenomenon" & proof that humanity has good going for it (even though I am convinced the world's messed up large overall)... apk
When referring to the kernel, it's just Linux, not GNU/Linux.
GNU has nothing to do with the kernel at all. The LiGnuX and then later gnu/linux renaming suggestions were for entire systems that contained software written as part of gnu projects and not a totally different project such as the linux kernel. The gnu kernel is called hurd.
The point of the renaming was stated to be to "advertise" gnu on the back of a higher profile project, but personally I think it was just petty MIT staffroom politics that escaped out into the world. "But what have you done lately Mr Stallman" turned into pretended ownership of linux which certainly has the above poster and a pile of journalists fooled.
Matt Blaze tweeted that Apple doesn't support the full resolution of the Retina display on the MacBook - the most you can set is 1920x1200, and it scales it from there. He also reports that there's a workaround which will let you get the full resolution.
But still, SRSLY? You'd think Apple could get font scaling correct, especially since they've been selling big desktop displays for years.

Back when I was running X Windows versions 10.x and early 11s, there was no requirement that I use TWM. And while the Sun 2 came with SunView, the Sun 3 could run either SunView or X, and you could get Grasshopper Group's implementation of NeWS if you preferred, which drove your screen in Postscript. Among other things, that meant that if you wanted to change the font size to match the size of your monitor and your eyesight, you just did it, and What You Saw Was What You Wanted. None of this "need a third-party developer's hack to use the full resolution of the expensive Retina Display you just bought" nonsense. But even if you were running X, you weren't limited to Motif or OpenLook; you could run whatever window manager you liked with it.
As far as "Ubuntu [does] not [have an SDK]" goes, you can use the Gnome SDK or KDE or LXDE or several other fairly full-featured SDKs.

AFAICT, Linux-libre takes the standard Linux distribution and removes all software that doesn't have source code, most of which is device drivers, and also removes applications that don't have politically correct licenses. I'm not too worried about applications (apt-get easily fixes that), but I'd rather not load it on my hardware and find I don't have device drivers for the screen or the audio card or whatever. Does using Linux-Libre mean I can't use AMD graphics sets, or NVidia, or both? What about Intel chipsets?

Any ideas when Ubuntu will support the 3.5 kernel? Real Soon, or not until 12.10?

some of us prefer blunt honesty over passive-aggressive politically correct doublespeak that dominates 'professional' interaction nowadays...those of us with spines, skin, and self-confidence anyway.
Linux, the kernel developed and distributed by Linus Torvalds et al, contains software that is included without source code, with obfuscated or obscured source code and code under non-Free Software licenses. Linux-libre removes these parts.

So, you're saying it is a lot, lot less functional, possibly even to the point of uselessness. Hmm. Doesn't sound like my cup of tea.
True, and it was an Intel chip, IBM PC, etc, etc, the list goes on through a lot of connections and will eventually involve Kevin Bacon. I think the connection is far too tenuous to name it after gnu and at least a few years ago the FSF agreed with me, suggesting calling linux the kernel and gnu/linux a distribution.
I remember Microsoft tablets, there's no doubt they were first...
Except they weren't, maybe you mean "they came before". Microsoft Windows for Pen Computing was a ripoff of GO's PenPoint from 1991, right down the the notebook metaphor in their promotional slides. PenPoint launched on tablet computers from IBM and NCR before Microsoft was able to cobble together their first demo. And before GO there were attempts such as Pencept and Momenta to interact with an LCD screen with a tethered pen.
- and unusable
Stylus computing works great for annotating existing content (cue AT&T's "Some day you will fax from the beach" ads) but handwriting recognition remains terrible, even 98% successful recognition means you stop every few words to correct. PenPoint and software written for the O.S. won awards but never got traction, just like Windows for Pen Computing never went anywhere. A web full of content to consume didn't exist and there were only a few vertical markets of doctors, insurance adjusters, and construction supervisors to mark up existing documents (and fax them from the beach).
It was just like a PC, except with a stylus instead of a keyboard
Yes, Windows for Pen Computing just added an ink layer to the desktop. It was the other companies that rethought interaction: besides GO, the later Apple Newton and Palm PDA innovated. PenPoint provides a huge trove of prior art for direct screen manipulation, tap and drag, other gestures, and novel metaphors for a bookshelf, notebook, and page-turning, which is why Apple hasn't been able to broadly patent IOS features.

Let me judge you by the way you abuse the English language. You don't need a double-spaced gap after every sentence or two. The first word in a sentence starts with a capital letter. You are a disgusting, uneducated buffoon. Your posts are not worth reading.
Customers? You are really making a fool of yourself.
Please mod parent funny. :)
You'll notice that lots of phones in todays world are like that.
Thanks though.

It was locked down in the aspect that the choices weren't there.
You bought a computer with MS-DOS, or Windows 95/98/ME/2000/XP/Vista/2008.
You could not go in say "ya know guy, I think I'd much rather put Novell DOS on there instead of MS-DOS." unless you bought a copy of Novell DOS as you bought your computer. Then, you had a license to MS-DOS & Novell DOS.
There, you see the problem.
Since we're talking about PC, I'll play the field that everyone seems to play and simply say that it's WinTel, not Apple.

MS Tax means you have to pay for it, because it's forced on you when you buy the computer and auto-rolled into the price of the computer.
Now that you know what it is, try to say it didn't exist. I admit I know dell is offering Linux with their computers now, but that's very recent.

Dude, the license is GPL, not GNU.

True. Apple is better than most at starting a trend. So now suddenly hardware-based keyboards are seen as less cool, at least as far as smartphones are concerned.
I thought the odd number minor number meant it was for the beta version for the next kernel. Has this changed.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
Has this changed.
Yes - a long time ago.
A word of warning, Linux Mint really needs to fix up how their installer drops X onto the system. The LiveCD will run great, but then you get all sorts of corruption till you get the right drivers installed.
It's a great distro - running it right now in fact - but oh god does that ever need to be fixed.
Relative to the market size, BSD has about the same amount of resources getting poured into it from corp. Licensing has little to do with it.
As this is such a fundamental and obvious failure in Ubuntu and the WDTVLive, has this been fixed yet?
If you want a useful answer to this question you'll need to clarify it a bit.
What do you mean by "select a network device too quickly"? The only thing it brings to mind is going into your local computer bits store and grabbing the first NIC on the shelf.
Likewise, "BAM, that's it". What sort of problem symptoms do you observe?
Keen to help, but more information needed.
The point is to give a name to the overall system, so people wouldn't confuse GNU/Linux with Linux systems that don't run GNU.
This point was made moot recently, as Androind made a precedent, and now it is impossible to use the name "Linux" for anything that isn't GNU/Linux. We settled at the most confusing nomeoclature that isn't ambiguous, but at least, it isn't ambiguous.
Rethinking email
bhahaha, Android market share has risen to 60% in the USA and climbing.
Apple phones are for the style-conscience, it's like those who spend $120 for a $30 pair of athletic shoes because the asian maker had license to slap a big name like Nike on it.
Your system is getting indications that it's about to fail (or you want to take it down for maintenance). You migrate all the currently-running tasks to another server (without the clients even knowing about it), then take down your server and do your maintenance.
"Linux would still have failed if it had not been backed by google .. and they used their resources to make Android Linux a success, by selling direct to manufacturers
...
That's incorrect, the reasonGoogle succeded was that the Android OEMs didn't have a special relationship with Microsoft. Which explains MS going after them in court with the 'Microsoft Tax`

Excuse me? You are definitely living in some kind of reality distortion field. While enterprise businesses and governments (mostly) bought their operating systems, that certainly was not the case when it came to smaller enterprises and especially small-to-medium businesses, small-office/home-office, nor the home user. They almost always just installed whatever suited their fancy from work or a 'friend'. I know since I'm the one the come to to fix their machines which, with very rare exception, running stock whatever. They don't buy it, in the words of Microsoft and the rest of the software firms, they steal it. They certainly steal the updgrades! And applications, with exactly one exception (a grandma), are nearly always stolen.
So in terms of costs, Linux is free, (PC/MS/Novell/Free/there's-many-more) DOS, or Windows, they might as well be considered free as well. Now you could almost make a case for apps, but you run into the brick wall of compatibility at work issue, so you are back to enterprise adoption and they'll adopt when they can make a total-cost-of-ownership case and not one second before. Free ain't really free when you have to factor in your IT staff (especially pay levels, since Window flunkies are dirt cheap) nor the training costs of your staff as well.
One last nit. I constantly run into people that can't grasp system administration chores but are complete at ease in using the latest jailbreak, application/operating-system crack, or other means of getting what they want at zero price (not cost mind you which involves other consideration such as time). This used to be true of music until the price came way down. I do notice that MS has the upgrade to Win 8 Pro pegged at a much lower price so it'll be interesting to see how many cracked machines I run into after its release. In any case, come back to me when you turn off the reality distortion field.

That's no longer the case.
Exactly the kind of a response I was expecting, thank you ;)
well then if the cursing is irrelevant, why get upset about it? focus on the content of the message, if it has any.
uh? what? cursing is supposed to show other people that you have self-confidence? quite the opposite.
not necessarily. I was talking more about the insane overreaction modern society has to it.
in many parts of the world, showing your anger (and that includes cursing) will cause you to lose face and lose respect.
that exposes a fundamental problem with most of the world. it focuses too much on presentation and not enough on respecting content, to the point of ignoring truth when it's too uncomfortable to swallow. 'saving face' is just social mechanism to hide behind for those with no rational criticism to a position they don't like. these people are welcome to not respect content they don't like the look of, but if that content is truthful, they're not causing the messenger to lose face, they're spiting their own.
In this case, torvalds is expressing public criticism and frustration at nvidia for their policies. Sometimes a simple 'fuck you' sends a much clearer and more meaningful message than passive aggressive corporatespeak. he wants them to feel his frustration.
Thanks.
