  • Upgraded from ubuntu 12.04 to 12.10 issues

    - by ubuntu novice user
    I recently upgraded 12.04 to 12.10 ubuntu and then all hell broke loose. Being more specific, I have a Compaq machine and its hard disk is partitioned into 3 parts, so when I installed Ubuntu 10.04, I installed it in windows, since then have upgraded with each new ubuntu release via the update manager without any problems. I have installed the 64 bit versions. 12.10 downloaded via update manager, and initial downloading of packages was without problems, however, as it tried to install the packages, error messages appeared. The first was one about missing lib files, but I clicked to continue, since I am a relative novice on ubuntu. It continued, and during the restart process, when it was powering down, the computer hanged on the shutting down bit without rebooting for more than half an hour, so I manually shut down the machine and restarted it. Then a new error message appeared stating could not find disk, and I hit the manual fix option, and it now boots to an empty ubuntu desktop with my wallpaper but no launcher and the graphics appears as if this was put on a 640 x 480 resolution, and the screen no longer fits onto my 19" LCD. I had to use Ctrl-Alt-T to log out and then restart from there. How can I resolve this issue. Please help!

  • Why does Ubuntu 12.10 Beta2 insist on commiting changes to the partition table?

    - by Uten
    Why does Ubuntu 12.10 Beta2 insist on commiting changes to the partition table even as no real changes has been done? This is a show stopper for me as I'm installing without a CD/DVD ROM. This is how I go about it. I downloaded the iso image and extracted vmlinuz and initrd.lz to the same folder I keep the iso image. Configured grub (0.9x) to boot /ubuntu/vmlinuz with the iso image like this: title ubuntu live-cd kernel /ubuntu/vmlinuz boot=casper iso-scan/filename=/ubuntu/ubuntu-12.10-beta2-desktop-i386.iso ro quiet splash initrd /ubuntu/initrd.lz boot This works well and I get a running livecd session. The iso image is mounted on /isomedia (or something similar). The spare HD space where I want to install Ubuntu is in the logical area (at the wery end of the disk). I have tried both to use the space as empty and preformated with ext4. After selecting the partition and selecting "use as ext4" and selecting a mountpoint (/) I get the message: "The installer needs to commit changes to partition tables, but cannot do so because partitions on the following mount points could not be unmounted" "/isomedia" (or something similar). Is this a "feature" of the installer? To insist that everything is unmounted even if no changes is nescesary (as fare as I understand). It's probably a safety feature but is it needed? I have cahnged layouts with parted and gparted (at the end of the disk) for years without any failures. I understand that booting the iso image like this is not the common way. But it is just such a beautifull way of doing it when you hav a running system and want to play with another. Any one had any success installing Ubuntu (12.10 beta2 ) like this? Best regards Uten

  • How do OSes work on multiple CPUs? [on hold]

    - by user3691093
    Assumption: "OS es (atleast in some part) should be written in assembly.Assembly programs are CPU specefic." If so how can one os run on different CPUs ? For example: how is that I can load Ubuntu on different systems having different CPUs (like intel i3,i5,i7, amd a8,a6,etc) from the same bootable disk? Does the disk contain seporate assembly programs for each CPU? Are these CPUs 'similar' enough to run the same assembly program? Is my assumption wrong? Something else.... Thanks for responding. I tried to find out in what way are the CPUs that I mentioned 'similar'. I came across the concepts of Instruction Set Architecture and Microarchitecture of CPUs.A CPU will understand a program if it is combatible with its ISA. Even if CPUs are 'wired up' differently (different microarchitecture) , as long as the ISA implemented on top is same ,the program will work. ARM and x86 have different ISA ( that why there are 2 windows 8 versions, right?). And if an app program is written in an HLL with compilers for both platforms we will saved from wasting time writing 2 programs. Did I understand anything wrong? Are there programs that can take a compiled program as input and produce a program executable on another CPU as output? Is it possible? (Virtualisation?) 32 bit windows programs do install on 64 bit windows ,dont they? Arent 64 bit CPUs 'differerent' from 32 bit CPUs? They do get seporate OS versions, right? Is this backward combatibility achieved using programes mentioned in (3) ?

    Hi folks: Using TeamCity with Perforce on the build server I'm setting up at work: It takes about 2 hours to check out the workspace each time I try to build.

  • How To Find Out If You are Using HTTPS Without $_SERVER['HTTPS']

    - by Chacha102
    I've seen many tutorials online that says you need to check $_SERVER['HTTPS'] if the server is connection is secured with HTTPS. My problem is that on some of the servers I use, $_SERVER['HTTPS'] is an undefined variable that results in an error. Is there another variable I can check that should always be defined? Just to be clear, I am currently using this code to resolve if it is an HTTPS connection: if(isset($_SERVER['HTTPS'])) { if ($_SERVER["HTTPS"] == "on") { $secure_connection = true; } }

  • Threading.Timer vs. Forms.Timer

    - by Jekke
    The short form of this question: When, if ever, is it appropriate to use the Forms.Timer in a multithreaded WinForms application? More specifically, I am architecting an application that uses multiple System.Threading.Timers to launch processes asynchronously, check queues containing the results of those asynchronous processes, and update the statistics to be shown by the application's main form. In an application like that, is it appropriate to use a Forms.Timer to actually check the application statistics and draw them to the main form or would that just throw a wrench into the application's smooth running?

  • What predefined macro can I use to detect clang ?

    - by Pierre Bourdon
    I'm trying to detect the compiler used to compile my source code. I can easily find predefined macros to check for MSVC or GCC (see http://predef.sourceforge.net/ for example), but I cannot find any macro to check for clang. Does someone know if clang defines a macro like __CLANG__ in order to know what is currently compiling my code ?

  • Python Class which checks input before passing to console (C) program

    - by Joseph Melettukunnel
    Hello, We are asked to write a web-frontend (in python) for a very complex (and old) console application, written in C. Since we have no access to the C Source Code, and we assume that there might be some unsafe methods, we'd like to check the input which will the passed to the console application. WebClient - Python Module - Console Application Do you have any suggestions or tips what we should check for? Right now we are only limiting the string length and filtering some (program specific) unallowed keywords. Thanks, Joseph EDIT: Will remove strings like %s because of format string attacks

  • FilteredTextBox - allow non-english characters

    - by superexsl
    Hey, I'm using the AJAX FilteredTextBoxExtender, but I'm not sure how to let it accept non-english characters such as é and á. I know I can manually add these in the InvalidChar's property, but is there an easier, more practical way? When using Regex, the [\w] seems to let it through, but I'm guessing the FTBE is using another system to check for valid characters? (I know I can use the regex validator, but for UI experience, I'd like a real time input check) Thanks for any suggestions

  • how to visualise/debug an imagemap?

    - by fearofawhackplanet
    I'm dynamically generating an imagemap for a chart tool I have. I was hoping to be able to set a border or color on the area tags so I could check everything was being generated with the right coords, but a little research shows this is not possible. So whats the easiest way to check my image map is correct? Are there any browser tools which will "visualise" the areas?

  • Naming booleans

    - by wrongusername
    If I only want to check if something is impossible or not (i.e., I will not be using something like if(possible)), should I name the boolean notPossible and use if(notPossible) or should I name it possible and use if(!possible) instead? And just to be sure, if I also have to check for whether it is possible, I would name the boolean possible and use if(possible) along with else, right?

  • Executing Custom Actions immediately in WIX

    - by jbloomer
    Is there any way to execute a custom action in WIX as soon as the first dialog (welcome) appears? The requirement is to check prerequisites, and some of those require a custom action. The custom action could be executed as we click to the next dialog, but then the standard WIX prereqs are determined apart from our custom prereq. (The custom action we need is to check that IIS 6 Metabase Compatibility is turned on and a registry search does not work on x64 machines with a 32-bit installer)

  • Implementing PyMyType_Check methods with Python C API?

    - by Paul D.
    All the Python-provided types have a check method (i.e., PyList_Check) that allows you to check if an arbitrary PyObject* is actually a specific type. How can I implement this for my own types? I haven't found anything good online for this, though it seems like a pretty normal thing to want to do. Also, maybe I'm just terrible at looking through large source trees, but I cannot for the life of me find the implementation of PyList_Check or any of it's companions in the Python (2.5) source.
