  • Why can't I upgrade my kernel via the terminal?

    - by Alvar
    If I type sudo apt-get update && sudo apt-get upgrade I can only see that the kernel packages are kept back, and not installed. As the screenshot shows. If I then start the update manager I can install the kernel, with no problems at all. As the second screenshot shows. Why is this? The kernel is a new package and not an upgrade of an old one, this is why you can't use the command upgrade that upgrades packages. You need to use the command dist-upgrade to install new packages.

  • How to test my programming experience

    - by Oden
    Hey guys, I'm very excited about how experienced I am in programming. The first, working program that I have written, was in 2004 with C. Since this I have tried many programming languages, now got stuck with php. Currently I'm working as a web-developer, and everyones pleased with the work I do. Except me :) Thats the reason why i want to know, how high my experience and my knowledge is. Could you tell me, some tips, tricks, test, or anything, on what I can see how much I need to learn and practice to get a mastermind in programming? (at first place in php)

  • updating to 3.0.0-18-generic linux kernel is causing system instability - and no backwords compatability

    - by Gaurav_Java
    I was prompted for an update of kernel 3.0.0-18-generic, so I upgraded and rebooted my system now its behaving really strange. Applications are crashing . System is randomly restarting Files are randomly disappearing off of my desktop I've tried booting into Linux kernel 3.0.0-17-generic but it doesn't help. Subsequently I am not able to connect to the INTERNET when I use the 3.0.0-17-generic kernel. Are there any ideas on what may be wrong? How I can go about debugging this?

  • Is there ongoing work in the kernel team to improve battery life under linux?

    - by leousa
    I have read in some forums that the kernel team is working on improving battery life and energy efficiency in linux. Unfortunately our community really lags behind windows and mac in that regard. I would like to read about the reasons why this difference exists with other platforms. Is it purely due to closed hardware specs from vendors or does it has to be with kernel design issues? Apple devices with unix cores have amazing battery times, but they also design their own hardware...just want to understand this issues in a less technical way I know that recent kernel updates in Ubuntu have improved the battery life in most computers, but I was wondering if there is still development going on and where can I read more about it. Thanks in advance

  • Ubuntu Server 11.10 AMD64: Installation of graphical desktop changes kernel!?

    - by MindGap
    I've a Ubuntu Server 11.10 amd64 installation that needed a graphical desktop to execute some visual apps. While searching for the correct way to achive this, I noticed that there was a lot of people saying that invoquing the gnome desktop installation (apt-get install ubuntu-desktop) would switch from server to desktop kernel. Is this true!? I've checked and the kernel seems to remain unchanged after the install. I need to be sure of this because the desktop flavoured kernel doesn't seem to support the ServeRaid 8K controller sitting on my IBM server and I have no ideia on how to enable support for it. (I'll be grateful if someone could point me a good guide on how to install ubuntu when the storage controller is not detected) Any comment on this matter will be greatly appreciated! Good linuxing!

  • Kernel NTFS driver vs NTFS-3G

    - by Jack
    A more comprehensive phrased question since I lost access to the other one. I would ask that the other one be deleted, not this one, as it should not have been migrated in the first place. There are currently two NTFS drivers available for Linux. The NTFS driver included in the kernel, and the userspace NTFS-3G driver that makes use of FUSE. By all accounts, NTFS-3G works perfectly. My question then, is if the NTFS filesystem has been successfully reverse engineered, why have the kernel NTFS team not implemented the changes in their driver? At the moment it is still marked as experimental, and there is a good chance it will destroy your data. Note: This has absolutely nothing to do with distributions...

  • Upgrading kernel on Debian server hosting Xen 3.2.1

    - by mitnosirrag
    I have a physical server running Debian 6 and Xen Hypervisor 3.2.1, and kernal -a says "2.6.26-1-xen-amd64". I have not updated for a long time, because when I run apt-get upgrade, one of the updates is linux-image-2.6-amd64. My understanding was that my kernel needs to have Xen support, will upgrading to this kernel break my dom0? I have myself up against a wall, because I host a VM for a website that isn't mine, so I need the latest security updates, but can't risk taking them offline. Eventually they will move off, and I won't be hosting something I am unqualified to host, but that isn't the point right now.

  • Linux kernel startup problems: how to analyze?

    - by java.is.for.desktop
    Hello, everyone! After manually updating the kernel from 2.6.33 to 2.6.34 on my OpenSuse 11.2 Notebook, it stops after the message Loading drivers, configuring devices... This stop can be interrupted with Ctrl-C, but when the system enters runlevel 5, no partitions are mounted (but the root partition), many services fail to start, and other strange things are going on. No X11. NOTE: I manually updated the kernel many times before, it worked. Yes, I know, in case of NVidia, the driver has to be recompiled. The question is: How can I analyze the cause of the problem? Doing dmesg gives me soooo much output, I can't "map" it to the output which I see at startup. The output does not contain the string Loading drivers, configuring devices, or similar.

  • V4L2 and ALSA: Kernel SPI or User API?

    - by pnongrata
    I'm trying to understand what Video for linux and ALSA are (exactly), and I can't discern whether they're APIs for Linux application to use (the userspace) or if they are backend services that are only available to the Linux kernel (sort of a kernalspace SPI). Or, if they are something entirely different. On one hand, those articles make it sound like its an API for applications to use. However, on the V4L2 page it has a section title Software supporting Video4Linux... So is V4L2 a library that applications use, or is it a module that "snaps into" the kernel? I'm so coonfused, thanks in advance.

  • How to benchmark kernel (-Os vs -O2)

    - by NightwishFan
    It seems logical to me that on a 64-bit kernel compiling it to optimize for size might help overall. (My distro of choice uses -O2) It has the benefits of more registers and memory and perhaps less cache contention than normal optimized code. I have a kernel compiled like this and it seems excellent. However my question is how can I prove this? I like using Phoronix for "real world" sort of benchmarks so I would prefer to test cases like that. What should I pick to test? Does anyone else have any alternatives? Thank you very much in advance.

  • Kernel compiling with -j2+ parameter ends prematurely with no error message or output bzImage

    - by Minix
    I've noticed quite a while ago that compiling a kernel with the parameter -j set to 1 or more doesn't produce a bzImage. Instead, it ends prematurely without any advice. I have reproduced the same behavior in both my netbook and home server. As far as I'm aware, the point where the compilation stops is random - Compiling twice with the same parameters will probably stop at different files. However, when I run make with no -j* parameter the compilation ends just fine and outputs a working bzImage. Both machines run Intel Atom (N270 on the netbook and 330 on the server) and I've compiled for these processors. If I recall correctly, I've tried compiling both with Atom and with generic x86_64 options. The kernel version I'm building is 2.6.34.1 I've always compiled normally with those options in my Core2Duo and Pentium Dual Core machines. Has anyone experienced this issue? Any ideas why does this happens? Is there a fix or workaround?

  • compiling the linux kernel

    - by user482819
    Just for learning, I have recompiled the linux kernel with different options, installed and boot from it. It was both instructive and straight forward. However, I was overwhelmed by the big number of options available. My questions are: 1.- Does it make sense to spend time trying to optimize the linux kernel for my particular laptop? Will it make a significant improvement? 2.- Is there any tool that can read the configuration of my computer and suggest a config? Thanks, H

  • iscsitarget suddenly broken after upgrade of the 12.04 Hardware Stack

    - by RapidWebs
    After an upgrade to the latest Hardware Stack using Ubuntu 12.04, my iscsi service is not longer operational. The error from the service is such: FATAL: Module iscsi_trgt not found.

  • problem in allocating kernel memory by malloc(),

    - by basu sagar
    Is there any protection provided by kernel? Because when we tried to allocate memory using an malloc(), the kernel allowed to allocated around 124 MB of memory, and when we try to write into it, the kernel crashed. If there was protection of kernel memory area, this wouldn't have happened, I guess.

  • Having trouble wrapping functions in the linux kernel

    - by Corey Henderson
    I've written a LKM that implements Trusted Path Execution (TPE) into your kernel: https://github.com/cormander/tpe-lkm I run into an occasional kernel OOPS (describe at the end of this question) when I define WRAP_SYSCALLS to 1, and am at my wit's end trying to track it down. A little background: Since the LSM framework doesn't export its symbols, I had to get creative with how I insert the TPE checking into the running kernel. I wrote a find_symbol_address() function that gives me the address of any function I need, and it works very well. I can call functions like this: int (*my_printk)(const char *fmt, ...); my_printk = find_symbol_address("printk"); (*my_printk)("Hello, world!\n"); And it works fine. I use this method to locate the security_file_mmap, security_file_mprotect, and security_bprm_check functions. I then overwrite those functions with an asm jump to my function to do the TPE check. The problem is, the currently loaded LSM will no longer execute the code for it's hook to that function, because it's been totally hijacked. Here is an example of what I do: int tpe_security_bprm_check(struct linux_binprm *bprm) { int ret = 0; if (bprm->file) { ret = tpe_allow_file(bprm->file); if (IS_ERR(ret)) goto out; } #if WRAP_SYSCALLS stop_my_code(&cs_security_bprm_check); ret = cs_security_bprm_check.ptr(bprm); start_my_code(&cs_security_bprm_check); #endif out: return ret; } Notice the section between the #if WRAP_SYSCALLS section (it's defined as 0 by default). If set to 1, the LSM's hook is called because I write the original code back over the asm jump and call that function, but I run into an occasional kernel OOPS with an "invalid opcode": invalid opcode: 0000 [#1] SMP RIP: 0010:[<ffffffff8117b006>] [<ffffffff8117b006>] security_bprm_check+0x6/0x310 I don't know what the issue is. I've tried several different types of locking methods (see the inside of start/stop_my_code for details) to no avail. To trigger the kernel OOPS, write a simple bash while loop that endlessly starts a backgrounded "ls" command. After a minute or so, it'll happen. I'm testing this on a RHEL6 kernel, also works on Ubuntu 10.04 LTS (2.6.32 x86_64). While this method has been the most successful so far, I have tried another method of simply copying the kernel function to a pointer I created with kmalloc but when I try to execute it, I get: kernel tried to execute NX-protected page - exploit attempt? (uid: 0). If anyone can tell me how to kmalloc space and have it marked as executable, that would also help me solve the above problem. Any help is appreciated!

  • KISS principle applied to programming language design?

    - by Giorgio
    KISS ("keep it simple stupid", see e.g. here) is an important principle in software development, even though it apparently originated in engineering. Citing from the wikipedia article: The principle is best exemplified by the story of Johnson handing a team of design engineers a handful of tools, with the challenge that the jet aircraft they were designing must be repairable by an average mechanic in the field under combat conditions with only these tools. Hence, the 'stupid' refers to the relationship between the way things break and the sophistication available to fix them. If I wanted to apply this to the field of software development I would replace "jet aircraft" with "piece of software", "average mechanic" with "average developer" and "under combat conditions" with "under the expected software development / maintenance conditions" (deadlines, time constraints, meetings / interruptions, available tools, and so on). So it is a commonly accepted idea that one should try to keep a piece of software simple stupid so that it easy to work on it later. But can the KISS principle be applied also to programming language design? Do you know of any programming languages that have been designed specifically with this principle in mind, i.e. to "allow an average programmer under average working conditions to write and maintain as much code as possible with the least cognitive effort"? If you cite any specific language it would be great if you could add a link to some document in which this intent is clearly expressed by the language designers. In any case, I would be interested to learn about the designers' (documented) intentions rather than your personal opinion about a particular programming language.

  • Functional programming compared to OOP with classes

    - by luckysmack
    I have been interested in some of the concepts of functional programming lately. I have used OOP for some time now. I can see how I would build a fairly complex app in OOP. Each object would know how to do things that object does. Or anything it's parents class does as well. So I can simply tell Person().speak() to make the person talk. But how do I do similar things in functional programming? I see how functions are first class items. But that function only does one specific thing. Would I simply have a say() method floating around and call it with an equivalent of Person() argument so I know what kind of thing is saying something? So I can see the simple things, just how would I do the comparable of OOP and objects in functional programming, so I can modularize and organize my code base? For reference, my primary experience with OOP is Python, PHP, and some C#. The languages that I am looking at that have functional features are Scala and Haskell. Though I am leaning towards Scala. Basic Example (Python): Animal(object): def say(self, what): print(what) Dog(Animal): def say(self, what): super().say('dog barks: {0}'.format(what)) Cat(Animal): def say(self, what): super().say('cat meows: {0}'.format(what)) dog = Dog() cat = Cat() dog.say('ruff') cat.say('purr')

  • First ATMs programming language

    - by revo
    First ATMs performed tasks like a cash dispenser, they were offline machines which worked with punch cards impregnated with Carbon and a 6-digit PIN code. Maximum withdrawal with a card was 10 pounds and each one was a one-time use card - ATM swallowed cards! The first ATM was installed in London in the year 1967, as I looked at time line of programming languages, there were many programming languages made before that decade. I don't know about the hardware neither, but in which programming language it was written? *I didn't find a detailed biography of John Shepherd-Barron (ATM inventor at 70s) Update I found this picture, which is taken from a newspaper back to the year 1972 in Iran. Translated PS : Shows Mr. Rad-lon (if spelled correctly), The manager of Barros (if spelled correctly) International Educational Institute in United Kingdom at the right, and Mr. Jim Sutherland - Expert of Computer Kiosks. In the rest of the text I found on this paper, these kind of ATMs which called "Automated Computer Kiosk" were advertised with this: Mr. Rad-lon (if spelled correctly) puts his card to one specific location of Automated Computer Kiosk and after 10 seconds he withdraws his cash. Two more questions are: 1- How those ATMs were so fast? (withdrawal in 10 seconds in that year) 2- I didn't find any text on Internet which state about "Automated Computer Kiosk", Is it valid or were they being called Computer in that time?

  • Pair Programming, for or against? [on hold]

    - by user1037729
    I believe it has many advantages over individual programming: Pros By pairing senior with relatively junior staff, the more junior can get up to speed with both project and computing experience, and the senior will re-think the problem in order to communicate with the junior, thus re-checking his own thinking (rubber duck principle!). At least 2 people will know about any single piece of work, if one person is away the other can cover, or if some one leaves a project knowledge transfer is easier. Two brains on a complex task is more effective, communication keeps the work free flowing and provides redundancy in decision making. Code is effectively reviewed as its being written, no need for a separate reviewing phase which requires a context switch as someone who has not been working on the piece in question would be required to understand and review the related code. Reviewing code on your own which you haven't written or architected is not fun, hence counter productive. Cons Less bandwith for performing tasks, lets say we have 4 devs, pair programming requires 2 devs per task, so we would be doing 2 tasks concurrently as a posed to 4. I believe this "Con" does not stand up as the pair programmed task would complete sooner and comes with a review built in for free! Ie the pair programming task would be more efficient and thus free up resources earlier. Less flexibility to chop and change tasks as two developers are tied into a task, when flexibility is required this could be a problem.

  • Development environment for embedded system

    - by Howard Lee Harkness
    I need to develop software in C/C++ for an embedded system. I have Debian 6 running off of a USB hard drive. I would like to be able to generate a stripped-down kernel with modules, and install them either on a CF card or a USB 'thumb' drive. I succeeded in building a Linux 3.6 kernel and running it in Debian off of the USB hard drive, but I am having trouble figuring out how to install it on the thumb drive. I would like a build cycle that looks like this: 1) Build module or kernel with desired software 2) Install it on thumb drive 3) Boot and test I would like to use the same system for both development and testing, if that is feasible. I am looking for resources and tutorials that would help me understand how to do this.

  • Parallel programming patterns for C#?

    - by VoidDweller
    With Intel's launch of a Hexa-Core processor for the desktop, it looks like we can no longer wait for Microsoft to make many-core programming "easy". I just order a copy of Joe Duffy's book Concurrent Programming on Windows. This looks like a great place to start, though, I am hoping some of you who have been targeting multi/many core systems would point me to some good resources that have or would have helped on your projects?

  • md/raid:md2: cannot start dirty degraded array, kernel panic

    - by nl-x
    After having made use of a remote power switch, my server did not come back online. When I went to the datacenter and reboot the computer on the spot I see the server booting (I see the centos progress bar with running almost all the way to the end) and eventually giving the following messages: md/raid:md2: cannot start dirty degraded array. md/raid:md2: failed to run raid set. md: pers->run() failed ... md/raid:md2: cannot start dirty degraded array. md/raid:md2: failed to run raid set. md: pers->run() failed ... Kernel panic - not syncing: Attempted to kill init!

The only backup I have is of /home and the database dumps. (Glad to at least have those though.) Since the server is an old Dell PowerEdge 1750 with no CD-ROM drive, I have no way of booting the machine from a boot disk. I also remember in the past that the server also wouldn't boot from a bootable USB disk. So the only way I know how to boot the server is to go to the datacenter, pick up the server and take it to the office. Screw open the server. Attach a cdrom drive to an IDE slot on the motherboard. And then boot it. I am hoping you guys could help me avoid this. I have looked a bit through the boot options and I found the following boot options. When CentOS is about to boot and interrupt the boot-countdown: CentOS (2.6.32-279.1.1.el63.i686) CentOS Linux (2.6.32-71.29.1.el6.i686) centos (2.6.32-71.el6.i686) I think the first configuration is the default one, because choosing that gets me to the above mentioned kernel panic. The other ones end with something like "Sleeping forever". I can press 'e' to edit boot commands, press 'a' to modify kernel arguments and press 'c' for grub command line. The command line gives a grub prompt. But I have no idea how to get the system to boot without (trying to) access the dirty partitions. What I want to do is off course: - boot the machine - check hard drive for errors - mark the drive as clean

  • tracing a linux kernel, function-by function (biggest only) with us timer

    - by osgx
    Hello I want to know, how does the linux kernel do some stuff (receiving a tcp packet). In what order main tcp functions are called. I want to see both interrupt handler (top half), bottom half and even work done by kernel after user calls "read()". How can I get a function trace from kernel with some linear time scale? I want to get a trace from single packet, not the profile of kernel when receiving 1000th of packets. Kernel is 2.6.18 or 2.6.23 (supported in my debian). I can add some patches to it.

  • Wireless not working with a RaLink RT3090
