back to article Linux kernel 3.9 lands

Linus Torvalds has unleashed version 3.9 of the Linux kernel. Key features in the release include caching for SSD storage, new processor architectures, power management improvements targeting tablets and phones, Chromebook support, and a nod towards Android. The caching change, present as the dm-cache target and currently …

    3.9 already??

    Is Linux in competition with Firefox now?

      I suppose it is, that is, if you think that 3 versions over 22 years is the same as 20 versions over 11 years.

      That's before you consider they are two entirely different versioning methods for entirely different software. When you think about actual releases, I imagine the Linux kernel easily has close to double the releases of Firefox, if not more - I can't be bothered checking that.

      Ultimately it doesn't matter if Firefox is version 20 or 200, so long as the version uniquely identifies a release, it is doing it's job.

        3 Version over 22 years

        Well yes, that is right and your points are valid. But version 3.0 was launched on July 22, 2011. Less than 2 years later we have already hit 3.9. Version 2 was lauunched on June 9, 1996.

        I think the OP was referring to the numbering inflation rather than complaining about promiscuous versioning. I thought that 11 down votes for that post a bit excessive.

        I t leaves me wondering if this post can beat his downvotes :)

      No. They are just version hungry, you should expect version 5 to be there soon. With all the bugs and the normal problems.

  2. lupine

    yes

    some of that sounds nice (SSD caching especially) but as i use debian stable on my servers i might get it around 2027...

    1. Skoorb

      Re: yes

      Seriously, why would you use Debian Stable? Even a Red Hat clone should be more up to date than that, and they certainly don't crash!

    SSD caching

    sounds very very nice. I guess that should lead to practically instant on for even my crappy old desktop - though I may have to clean out an ISA slot for an SSD card!

    @eadon "The Linux Desktop is cool, named after a god and mankind desperately wants to go there."

    Let me fix that for you...

    1.17% of mankind who use a desktop desperately wants to go there.

    1. h4rm0ny

      @spoddyhalfwit. Don't let Easdon provoke you into negative attacks. GNU/Linux has loads to offer. Windows is good too. These things are not mutually exclusive. Linux powers at least half of the Internet for a start. Not to mention the Linux kernel being a critical part of Android. If you like Windows (I do), then Linux was one of the best things that happened to security in Windows by pushing MS to compete against a better opponent ten years ago. It's not a war, even if posters like Eadon want to make it one. Chill.

        @harmony

        My comment wasn't negative. Linux is great I'm glad it's there.

        Eadon logic dictates that market share is all when it comes to windows phone. Applies different logic to desktop.

        Facts are that Linux isn't breaking through on the desktop, and to me that is partly because of people like eadon.

        1. 1Rafayal

          @harmony, completely agree with you on that. Without choice, the options available will just stagnate. Linux has caused Windows to evolve and I think the same is the other way around to a certain extent (desktop experience, installation etc).

          @spoddyhalfwit, I think the take up of Linux by the regular home user boils down to a few points:

          - They dont want to use

          - They dont know how to get it

          - They dont know how to install it

          MS has some advantages, they make a product and let people know all about it and offer help on how to use it. Additionally, there are only a couple of flavours of Windows, Server and not-Server.

          Linux, on the other hand, has multiple distros all trying to get attention. You have Mint for instance, which is fine for most users but then you get things like RHEL which has more flexibility but little support for media etc (I chose those two on purpose).

            I reckon the majority of them don’t know its there to use. If you started shipping Ubuntu out on laptops like windows I reckon people would look at it and say wow that looks pretty nice. I will just install iTunes and move my music over.......oh no wait. Obviously you can sync music buts it not as easy as plugging it in and the PC doing it for you.

            I think its as simple and as complicated as that. Simple applications that people use like iTunes, Netflix etc etc. They just dont work on Linux.

            1. Pete Spicer

              Actually one manufacturer did ship both for a while, forget who it was, might have been Dell, and they got a lot of returns because people didn't understand/realise it wasn't Windows and they couldn't use the software they'd bought elsewhere.

              Iwill just install iTunes and move my music over.......oh no wait.

              Or, wait, that's crApple's decision, iTunes is completely locked-in stuff. So neither Linus, nor MS, nor even Ubuntu have anything to do with it. You can move your music back and forth with other tools though. However, noway to activate an iDevice. Who would care about iShite anyways? crApple doesn't even bother about FreeBSD. What a nice irony?

            As someone running a Linux home office here...

            I have an Xubuntu desktop and a Centos 6.3 server (also running a couple of VMs under KVM). For the server stuff, Linux just runs and runs and runs. For the desktop stuff, I still have niggles.

            Honestly, is there a decent RDP client for Linux, because I'm running Remmina, and whilst it's close, I still have lots of issues with it. Also locking up whilst playing music (or it might be Flash - nothing is logged),and YP is a bit of a pain in the arse. I'm going to get around to an LDAP setup, but it's a faff.

            For all it's faults, Windows tends to just work straight away. At the same time, I'm glad to have a little space from it. Oh the dichotomy!

              Technet is your friend, as is the Windows online help, but like UNIX/Linux web pages and man pages you have to know what your problem is, in order to resolve it. This is why you'll always need IT professionals whichever OS you use, as there needs to be someone to tell the end user what the problem they've got actually is.

                When trying to decrypt the "Windows has encountered a system error f3-f100-0010 and will have to shut down" Windows 7 error message, found 3 explanations:

                1) it's malware, remove it/ reinstall Windows

                2) it's you hdd dying (none was suggesting hdparm tools though), ran hdparm test off a live Linux media ruling this out

                3) MS people pointed fingers at Toshiba, Toshiba mirrored it back to MS

                Running Linux Mint/Ubuntu was a more straightforward business. Logs are most of the time are your friend. Things are more logical. At first, although laptop did not shut itself down out of the blue, wifi would stop working rendering the rtl8192ce driver useless until the next reboot (!!!) . Just get a fresher mainline kernel, it just fixes it.

                Nevertheless, the most competent Windows tech person will almost always suggest you to either find a better AV or reinstall Windows.

            Problem of definitions

            MS is a for-profit organisation strong enough to compel/convince OEMs to bundle MS on their machines.

            "Linux", bar a few exceptions, is non-profit "community" that generally doesn't give a damn about "getting on the desktop". You can take or leave it. No Linux user loses anything from your not using it.

            The plethora of "Distros" (versions of Linux/GNU) is not confusing. It's liberating. You can choose exactly what you want for the job.

            Personally, once I've shown friends and colleagues my Linux setup, they go for it. Disregard the propaganda put out by the CLI ranters. Linux is easier, safer, more flexible than MS or Apple. And it's free.

            The few for-profit Linux organisations eg Redhat, Canonical, Novell, are increasing market share, admittedly not always on the desktop.

            And, er, the other 10 flavours.

            But, otherwise, yes MS has a huge advantage in that they have a large advertising budget and they have the monopolistic power to force their product onto almost every new desktop computer sold.

            Where MS don't have that power, Linux is pretty well tied for users with iOS and is probably going to overtake that soon.

          Ah, I see. It wasn't clear from your post that you were highlighting Eadon's double-standards, I thought you were taking an unwarranted shot at Linux. He really is hugely destructive to debate.

    1. 1Rafayal

      Re: @1Rafayal

      dont get me wrong, Linux has come a long way with regards to installers over the years, in some respects they are way better than the Windows equivalent - the ability to spin it up live off the disc or USB drive is one of them.

      As far as the user experience goes, there is still some way to go before the average punter will strongly consider replacing Windows. As Bill The Sys Ad mentioned, people want iTunes etc. If they can get things like that then I dont think they would care one bit about their OS.

      At home, there is a whole bunch of things that need to be done to push Linux. In the workplace, its a different matter completely. Will the average home user care about things like disk caching, SELinux, Jboss etc? No, they will probably care about Facebook, Skype, iTunes, Spotify etc

      I remember in the mid 90's when PC magazines provided Red Hat on the cover disk, its things like this we are missing in modern times. Maybe some enterprising group will start handing out distros at the tube, train stations etc. That would get people thinking

      1. Spoddyhalfwit

        Re: @1Rafayal

        "Maybe some enterprising group will start handing out distros at the tube, train stations etc. That would get people thinking"

        I think most people with the skills to use those would probably be aware of Linux already.

        I tried Red Hat years ago and was surprised at how easy it was to install - since then I've installed Mint and Ubuntu and both were easy to install.

        I think the big reason most people don't use Linux on the desktop is because they are largely happy with Windows. They like the fact that they are running the de facto standard, because as others have posted it means they have no problem using the programs they want to use. Its the same reason Windows Phone is going to struggle to gain market share - its not to do with the quality of the product (which has received good reviews), ultimately most people will stick with what they know unless they have a very pressing reason to change.

        I thought Windows 8 might provide that reason, but looks like MS might be fixing the problems with that in a future release.

        1. 1Rafayal

          Re: @1Rafayal

          largely happy with Windows sums it all up really. I have long believed that the consumer doesnt really care about the OS, as long as it does what they want it to do.

          I really think there is an opportunity for some group or organisation to go giving out free distros on a cd or a USB drive though. If there was a larger appetite for Linux in the consumer market then we would quickly see things like iTunes on it etc, well, I would like to think that would be the case.

          What is their choice? Yeah, it's like voting back in the USSR. It's democracy, right. So you have the right to vote. Fine. How many candidates are there? One. Can you vote against him/her though? No? Are you allowed to not vote at all? No.

          The current Windows 8 EULA providing no declining options might be borrowing its letter "U" from the USSR voting system.

            Actually the USSR did have the "none of the above" (против всех) option in ballots. How effective it was in "elections" that were otherwise seen as rigged is another matter.

              I id not mean the the last years of Perestroika, but the first 70 years of it. The "против всех" thing came only in 1987 right before the collapse of USSR. I think it has been removed recently from the ballots in modern Russia yet again.

    Quick Noob Q.

    Silly question from someone who simply does know.

    Can the kernel be set to override UEFI BIOS and get around this whole MS lock down of motherboards? I am looking at a new Linux home machine on new hardware. My new Mobo has UEFI, so it is a concern obviously.

    1. Anonymous Coward
      Anonymous Coward

      Re: Quick Noob Q.

      Secureboot is a function of uEFI, BIOS is nothing to do with uEFI/EFI excepting that uEFI/EFI is what was designed by the vast majority of hardware and OS manufacturers to replace BIOS.

      Secureboot cannot be switched off by the Kernel, it wouldn't be very much use were that the case, however if you want to use Linux you've got three options:

      1) Many Linux distros are signed by MS, in order that they can be installed on systems which only have MS' keys on them.

      2) You can enter your own key into the uEFI yourself and compile the appropriate portions of the kernel signed with your personal keys. It's also entirely possible that some distributions will give you a key to enter yourself and use non-MS signed bootloaders.

      3) You can switch secureboot off. This is a pretty important requirement, not least because you're not going to be installing versions of Windows prior to v8 if it weren't there.

      I have Windows 7 installed on a uEFI Thinkpad and Ubuntu installed on a random Intel mobo which has uEFI, I switched secureboot off to install both. I may have a look at installing a more recent version of Ubuntu with secureboot switched on at some point.

    3. eulampios

      Re: Quick Noob Q.

      Hopefully, the OEM you choose would let you boot off a usb media by turning secure boot off. Even if it is possible it might have some secret option to be turned on/off within the EFI interface, before you can do just that.

        It's not possible that you may be able to switch off secureboot, it's required. I have installed oses which don't support secureboot on a a few systems without a problem and have never, even anecdotally, heard of a system that won't allow you to turn it off.

        it is possible it might have some secret option to be turned on/off within the EFI interface, before you can do just that.

        The UEFI standard is just that - a documented standard shared created by a large range of big hardware players from AMD to Apple to Intel to Lenovo. There wont be "secret options" to turn on Secure Boot against the user's will. There's no such option in UEFI and no-one wants to fake a UEFI system.

        1. eulampios

          @h4rm0ny

          We've heard it from you already. I know at least two OEMS, with products I had to deal myself. Say on Acer machines turning off secure boot only if you have set a BIOS/EFI password. No other OEM is known to require it. It's not in those (U)EFI docs. Neither do you receive documentation with an Acer machine purchase. Asus got another option to turn off prior to booting from an external media.

      You'll be fine. Part of the requirements from MS for Windows 8 certification actually specify that a physically present user must be able to turn Secure Boot off. Additionally, with some GNU/Linux distributions, you wont even have to do that as they have signed boot loaders. The Secure Boot hysteria was actually a big piece of FUD from MS critics. Meanwhile, Google's Pixel, that can only have your choice of OS installed on it by repeatedly putting the device in developer mode everytime you boot, has passed with nary a whisper of criticism.

      1. eulampios

        anti-MS FUD

        Lack of the Microsoft Win8 EULA decline button is also someone's FUD? The Linux community doesn't have money to squander on FUD, like some people in Redmond, it is not a "don't get scroogled" campaign. UEFI is a pain in the arse but seemingly not enough for Microsoft, so they came up with the new EULA that you always agree with!

    Rolling development project

    Just think of the Linux Kernel as exactly that. At least the new support will get tested by its peers (ie us in the IT world) and it's documented as to problems and tweaks to get it to work better than previous versions. It'll never be perfect, but at least its open development community keeps it, well, open. In contrast to maybe using paying customers to effectively beta test your products.

    Also consider that although you may think Linux is somewhat fragmented, as it's the choice you can have in its configuration, it does have the edge IMHO in innovation terms.

    Old pattern

    Lately Im witnessing a pattern from years ago: someone trolling with an apparent bias toward Linux and then an horde of supposed balanced people fighting the troll with the classic "Linux is good and all BUT WINDOWS blablabla...", but now you have Android and WP8. Looks like a self-preserving strategy, like when cheap netbooks with linux threatned Windows XP and ultimately the lunch of Windows 7.

    An article talking about a new release of the Linux kernel with interesting new features ends to be infested with comments about Linux as an OS desktop vs Windows. Microsoft is doing a good job shooting in the foot, with Windows Vista, weird decisions in 7, the Ribbon and now with W8. GET OVER IT. With Android and iOS they are contacting with alternatives and if WP8 its not doing well its because of 2-3 simple things: the steps needed to access the app store, no apps enough and because ordinary people HATE it after 2 weeks using it. I know because they bang on my door to help them after the HR dept swapped the old 6.5 phones for WP7.5 and 8 phones.

    Having said this, Linux kernel development its not going disappear overnight, not matter what, its been here for more than 20 years. It have been mainstream on the server camp and appliances. Now its mainstream on mobile. And the march to the desktop, albeight very slow, it will happen. You know why? The "IT guy" started to refuse to clean windows machines and offer to install and support the new linux desktop users...
