• How to install programs downloaded from the internet?

  - by Rosamunda Rosamunda

  I've downloadad the latest XAMPP file, to install it into Ubuntu 13.04. After downloading the file, I just can run it. I've double click it (and I've tried right click and clicking "open", whith the same result). All the answer I get is this message: Could not display “xampp-linux-1.8.3-1-installer.run”. There is no application installed for “executable” files. Do you want to search for an application to open this file? I've tried searching for an application, with no result... Also, I haven't found any questions related to this issue with the 13.04 Unity version... I've tried this solution, with no result. Please note that this isn't a Xampp question, the same happened to me when I tried to install Skype. UPDATE: I've tried this solution: cd ~/Downloads chmod +x myfile.run sudo sh myfile.run And I've got this error: Syntax error: "(" unexpected What should I do? Thanks!

• how to avoid or minimise use of check/conditional statement?

  - by Muneeb Nasir

  I have scenario, where i got stream and i need to check for some value. if i got my any new value i have to store it in any of data structure. well it seems very easy, i can place conditional statement if-else or can use contain method of set/map to check either received is new or not. but the problem is checking will effect my application performance, in stream i'll receive hundreds for value in second, if i start checking each and every value i received than for sure it effect performance. Any body can suggest me any mechanism or algorithm that solve my issue. either by bypassing checks or atleast minimize them?

• Gateway laptop module bay light repeating 12 flashes - what error is that?

  - by Simurr

  I have a Gateway M465-E laptop currently running fine with a T2300E Core Duo installed. I wanted to upgrade it to a Core 2 Duo. My brother has the same model laptop and that took a Core 2 Duo (T7200) just fine. Picked up a T7200 on ebay and installed it. Normally when booting all the indicator lights flash once and the fan spins up before the machine actually starts to POST. With the T7200 installed all the lights flash and the fan spins up, but the module bay activity light flashes 12 times repeatedly. I'm assuming this is an error code, but can find no information about it. There are no beep codes. I've removed the ram, HD, Bay module and no change. Switched back to the T2300E and everything works fine. Anyone know what that error code is? The motherboard was actually manufactured by Foxconn if that helps. Update 1 Returned the CPU as defective. I tested it in 3 M465-E's and all of them did exactly the same thing. I still have no idea what the error code is. I'd still like to know for future reference. Perhaps I should try removing the CPU from one of them and see what happens.

• Wifi worked after reinstalling the driver, but why did it stopped working in the first place?

  - by Ankit

  I was having an issue with connecting to my wifi router since yesterday; could see the router in the wireless networks available but the router was not authenticating my password. I tried unblocking the hardware switches though non was blocked. Finally on discussing with the ISP i gave a re-installation of the wireless driver a try; and to my surprise that worked.(I was assuming faulty wifi router). So as per the subject of the question; I am very curious to know what actually happened that prevented me to connect to my wifi. Any logs that I could see to confirm the cause of this suspicious activity.

• Unstable wireless connection on Ubuntu only (router config problem?)

  - by crunch

  so I'm using Ubuntu 14.04 and I could connect to all Wi-Fi's that I've tried and it worked fine... Except for this router that I have at home. This connection seems to be unstable, it just randomly disconnects and reconnects. On the same machine I have Ubuntu 13.10 (same problem) and Windows 8 (no problem). Also there are no Wi-Fi problems when I connect with my Android phone. So I figured it must be some config issue. I tried tweaking some settings/restoring default on the router but I don't really know what I'm doing so, unsurprisingly, it didn't fix the problem.

• Has anyone had issues with Google Analyticator authenticating?

  - by Marc Benzakein

  I'm using Analyticator on a site and am having an issue. I am getting an error (see below) when I go to authenticate from the settings panel on Analyticator. The structure on this is a bit different and I think that's what is causing it. The website is on a subdomain which is hosted on a different server than the top-level domain. The analytics account on google only has the subdomain listed. Is it possible that the reason for the error is that the primary domain either: A. doesn't have an Analytics account or B. does have an Analytics account but it is not linked to the Analytics account of the subdomain? The page you have requested cannot be displayed. Another site was requesting access to your Google Account, but sent a malformed request. Please contact the site that you were trying to use when you received this message to inform them of the error. A detailed error message follows: The site "http://xxxxx.com" has not been registered.

• poor performance while exporting data to excel from DB2

  - by Naga

  I am facing a performance issue while exporting data from DB2 to Excel 2003. Well the very first reason is file is about 10+ MB where it goes outofMemory Exception. I am using XLSTransformer and HSSFWorkbook classes to transform my xls file. I also have joins in my query( optional). But user most likely is going to choose these options. When they do so, of course, the data becomes huge and take lot of time and some times goes outOfMemory too. So Please advice me on this.

• How can I get gcc to write a file larger than 2.0 GB?

  - by fred.bear

  I wanted to recompile 'xxd' (written in C), so I installed CodeBlocks as the IDE. All seemed to go well unil I discovered that I couldn't write past the 2.0 GB barrier... I've read that 'gcc' needs to be recompiled... (That sounds a bit dramatic..) I've read that I can use 'fread64()' instead of 'fread()' ... (didn't work) I've read something about a compiler options (?)... but I get lost at that point? I am surprised that it didn't work out-of-the-box, as I thought the 2.0 GB limit was ancient history as far as defaults go ... wrong again?:( My OS is 32-bit, on 32-bit hardware. The gcc version report in as: gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3 Is there a simple way around this issue? PS.. I was fascinated by the WARNINGS: section of 'info xxd' (..only on Linux ;)

• No Launcher or bars on desktop when running from a VPS

  - by jeff

  I'm using tightVNC on Ubuntu 12.10 and can see and change the desktop background pic. I can also press f3 to get a file viewer. But there is no topbar or left side launcher. I do not think its an nvidia problem because I'm using a VPS and I logon remotely. I've tried so many variations of /root/.vnc/xstartup such as gnome-session &, or gnome-session –-session=gnome-classic &, my head is spinning. I've seen other people have this issue and was wondering if anyone solved it.

• Alternatives to using cookies?

  - by theclueless1

  Whate are alternatives to using cookies/client-side storage for a PHP/MySQL based site on Apache. Scenario/Requirements: I want to try using some anti-bot code to prevent specific scrapers etc. from accessing the site. I would like to run this code before launching the rest of the site (before DB access etc.). I don't want to constantly run the same code on every page-load after a visitor has passed the initial check. I'd like to avoid the use of Cookies/Client side storage if at all possible. The only solution I can currently think of is to write files to the server based on the visitors IP/UA, or to write a list of them to a single file. Yet this has the limitation of multiple users through a proxy/same connection, etc ... So, any ideas/suggestions? Or am I simply over working the issue?

• VMWare Player pauses often

  - by pascal

  I'm using a 64bit Windows 8 inside vmplayer, with 2 virtual processor cores, virtual hard disk resides on a fast local disc and is not preallocated; host CPU is Intel i7 3770, should be capable of hardware virtualisation but I don't know if VMWare uses it; NAT networking; Sound card connected, USB connected, accelerated 3D graphics (NVidia 313.30 on host) My problem is, that the VM often pauses for a few seconds, and then speeds up for a few seconds to reach real time again. Time in the VM actually moves faster after the pause, for example all animations using timers speed up. When running, the vmware-vmx process shows ~150% CPU usage in top, but 0% when pausing (and D state i.e. waiting for IO). iotop shows normal disk writes from vmware-vmx threads, but during pauses, the flush kernel thread uses 99%. Are there some options to try so that VMWare doesn't wait for IO? I've tried a few things available from the GUI but the issue never went away…

• Repairing Windows 7 boot after Ubuntu 10.10 install

  - by Ted

  I've read various threads on this after googling, including one on this site. I had Windows 7 installed on an SSD. I wanted to try Ubuntu so I created a partition for it on the SSD and booted with the live CD to install Ubuntu. Went through the install and somehow Ubuntu carved out another partition on the SSD rather than using the one I had already created. Windows 7 would then not boot but Ubuntu would. I booted with my 7 cd and ran the automatic startup repair, it didn't find any problems. I then ran the bootsect command on the drive with 7. It said it repaired the bootmgr but Windows still would not boot and now Ubuntu won't either. I read somewhere else that it may be due to the partition that 7 was on being changed during the install. I don't care about the Ubuntu installation but I don't want to lose the 7 install, can I delete the ubuntu partition through booting with the 7 cd? Will that do any good? Thank you all! I'm stumped even though I've done startup repairs before, just not after Ubuntu install.

• Video playback not working in Ubuntu 11.10

  - by Dave M G

  (Ubuntu 11.10, Gnome Classic with Compiz, Nvidia graphics card) This problem occurs with every and all video, whether it's a Youtube video in Firefox, an AVI file in movie player, or any other video. Video simply does not work. When I start any kind of video, the image halts after a second or two. The sound, however, continues. Before it seemed that if I delete all the files in ~/.gstreamer-0.10/, then reboot, the video will play. However this is no longer the case. Manipulating files in that directory does nothing to help the situation. I am now no longer sure this is a gstreamer issue or something else. I am open to any and all possibilities. How can I get video playback to run smoothly on my machine?

• Unrelated Files Corrupted on System Restore

  - by Yar

  I restored OSX 10.6.2 today (was 10.6.3 and not booting) by copying the system over from a backup. The data directories were not touched. In the data directories, I'm seeing some files as 0 bytes, and getting permission-denied errors when copying, even when using sudo cp or the Finder itself. Some programs, differently, take the files at face value and see no permission problems (such as zip), but they see the files as zero bytes, which would be game-over for recovery. cp: .git/objects/fe/86b676974a44aa7f128a55bf27670f4a1073ca: could not copy extended attributes to /eraseme/blah/.git/objects/fe/86b676974a44aa7f128a55bf27670f4a1073ca: Operation not permitted I have tried sudo chown, sudo chmod -R 777 and sudo chflags -R nouchg which do not change the end result. Strangely, this is only affecting my .git directories (perhaps because they start with a period, but renaming them -- which works -- does not change anything). What else can I do to take ownership of these files? Edit: This question comes from StackOverflow because I originally thought it was a GIT problem. It's definitely not (just) GIT. Anyway, this is to help put some of the comments in context.

• INACCESSIBLE_BOOT_DEVICE after installing Linux on same drive

  - by kdgregory

  History: My PC was configured with two drives: an 80G on IDE 0 Primary that was running Win2K, and a 320G on IDE 0 Secondary that was running Linux (Ubuntu). I decided to pull the 80Gb drive out of the system, so dd'd the entire 80 G drive (/dev/sda) onto the 320 (/dev/sdb) -- this included the MBR and partition table. Then I pulled the drive, plugged the 320 into IDE 0 Primary, and rebooted. The Windows partition worked at this point. Then I installed Ubuntu into the remaining space on the 320. It works. However, when I try to boot into Windows, I get a BSOD with the following message: *** STOP: 0x0000007B (0x89055030,0xC000014F,0x00000000,0x00000000) INACCESSILE_BOOT_DEVICE Before the BSOD I see the Win2K splash screen, and it claims to be "starting windows" for a couple of seconds -- so it appears that the first stage boot loader is working as expected. Ditto when I try booting in Safe Mode. After reading the Microsoft KB article, I booted into the recovery console and tried running chkdsk /r. It refused to run, claiming that the drive was corrupted (sorry, didn't write down the exact error message). However, I can mount the drive from Linux, and access all files. And for what it's worth, I can scan the drive using the Linux "Disk Utility" (this is Ubuntu, the menus don't show real program names), it claims the drive to be clean. The KB article mentioned that boot.ini could be the problem, so here it is: timeout=10 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows 2000 Professional" /fastdetect Any pointers on what to do next?

• Getting Started with Component Architecture: DI?

  - by ashes999

  I just moved away from MVC towards something more component-architecture-like. I have no concept of messages yet (it's rough prototype code), objects just get internal properties and values of other classes for now. That issue aside, it seems like this is turning into an aspect-oriented-programming challenge. I've noticed that all entities with, for example, a position component will have similar properties (get/set X/Y/Z, rotation, velocity). Is it a common practice, and/or good idea, to push these behind an interface and use dependency injection to inject a generic class (eg. PositionComponent) which already has all the boiler-plate code? (I'm sure the answer will affect the model I use for message/passing)

• Managed servers getting down regularly by Node Manager. WAD?

  - by csoto

  Recently I have been working on a service request where several instances were running, and several technologies were being used, including SOA, BAM, BPEL and others. At a first glance, this may seem to be a Node Manager problem. But on this situation, the problem was at JMS - Persistent Store level. Node Manager can automatically restart Managed Servers that have the "failed" health state, or have shut down unexpectedly due to a system crash or reboot. As a matter of fact, from the provided log files it was clear that the instance was becoming unhealthy because of a persist6ent Store problem. So finally, the problem here was not with Node Manager as it was working as designed, and the restart was being caused by the Persistent Store. After this Persistent Store problem was fixed, everuthing went fine. This particular issue that I worked was on an Exalogic machine, but note that this may happen on any hardware running Weblogic.

• USB drive was bootable, but no longer isn't

  - by i-g

  I'm trying to install a new OS onto a computer from a bootable USB stick. I previously installed Ubuntu Linux and it was a piece of cake -- I downloaded the ISO image, used UNetbootin to copy it to the USB drive and make it bootable, and that was that. Now, however, no matter what I try, I can't make the same USB drive bootable again! I've tried formatting it as FAT32 and NTFS. I've tried several different Linux distributions and Windows 7. I've tried using UNetbootin, Windows 7 USB Download Tool, WinToFlash, and manually making it bootable with diskpart/bootsect/bootrec. (Yes, I've tried bootsect /nt60 x: /force.) None of this seems to be working! When I try to boot from the drive, the machine reads from it (I can see the drive's LED blinking) and then gives me the same "Insert system disk and press Enter" message. (I've disabled booting from the hard drive.) Am I missing something I need to do to make the USB drive bootable again? The USB drive in question is a SanDisk Cruzer 8GB SDCZ6. The computer I'm working on is running Windows Vista SP1.

• XNA content.load Dependancy

  - by Richard

  Quick question, My project i'm building for test purposes is working fine but i have dependencies flying around everywhere due to the XNA framework. In Update i have gametime passed everywhere... this is okay. In Draw i have gametime & spritebatch passed everywhere... this is okay. My issue is in the content.load textures/sounds/fonts. I have them as public variables ie Texture1 = Content.load(of texture2d)("Texture1") I'm passing a 'Game1' pointer into the constructor of every new class being instantiated to gain access to these variables. Am i missing an OOP trick to prevent me having to pass a pointer to 'game1' to every New class?

• Do navigation menu links negatively impact SEO for pages' content?

  - by Rodolfo

  I've always had my doubts about navigation menus effect on SEO. You know, the vertical menus on the top that show in every page in the site linking to main sections and subsections. My issue is that if not done dynamically (i.e. after page is loaded or something), from a search engine's point of view it probably looks like a whole bunch of links in the beginning of the page, and links that probably have nothing to do with the page being analyzed, so it's probably not only confusing it, but also giving link 'juice' to the wrong pages or reducing its value. When I've asked SEO people about this, I usually get a "Google is smart, they'll recognize it as a menu and ignore it" response, but I'm not convinced (and the 'Google is smart' argument sounds almost like religion discussion to me). So does it affect SEO negatively or not? Are there any official posts on this topic?
