  • Cannot change permissions in symlinked dropbox directory in Ubuntu 10.10

    - by Reactor5
    Title pretty much says it all, but here's what I'm doing... ls -l produces this... drwx------ 1 brian brian 4096 2010-12-28 14:19 foldername -rw------- 1 brian brian 0 2010-12-28 15:54 index.html after typing something like chmod o=rx index.html the output of ls -l is the same. This happens whether or not I'm in the original location or the symlink location. However, as a further twist, the output of chmod -v o=rx index.html is the following: mode of `index.html' changed to 0605 (rw----r-x) The location is also being symlinked to by apache. What's going on with my permissions?

  • Can't boot from SATA dvd, seen as SerialCH1_Master

    - by dierre
    Here's the problem: I have an old computer based on an AsRock motherbord, the p4vt8+. I have 2 IDE HDs , one per each channel (IDE0 and IDE1) and I have a SATA dvd LG GH22N550. When I go into the BIOS panel on the boot devices list I can see IDE0 and IDE1 but not the dvd that I need to install Windows. When the computer is booting I can see it under the voice SerialCH1_Master. I know I'm doing something wrong but I can't figure out what it is.

    The mouse pad on my laptop has stopped working. It has not been turned off as we already checked. The computer tech stated it was a windows 7 problem. The laptop is only 3 months old. They suggested that I try to run a recovery. However, I put the disk in and nothing happens. How can this problem be fixed?

  • slow internet Problem on kubuntu 9.10 amd x64

    - by Abdelkrim-NET
    Hi everyone, i've recently installed kubuntu 9.10 amd x64, on an HP 6830s. The installation went smoothly, with only one problem: when I try to use the internet, it's incredibly slow. I couldn't install Firefox or anything that requires the internet. I have tried most of the solutions I found through Google, but none of them solves the problem. If anyone has an idea, I would appreciate the help.

  • IE11 throws error in IEFRAME

    - by c69
    When I try to see "properties" of JSFiddle's logo, IE11 shows script error in file res://ieframe.dll/anchbrws.js Looking at the file, I see function BodyLoad() { var arrAll = document.all; for (i=0; i < arrAll.length; i++) { var elm = arrAll[i]; if (elm.id.substring(0,1) == "_") { if (elm.innerText== "undefined" || elm.innerText == "") { elm.innerText = L_NotAvailable_Text; } } } } from what I see, trying to read document.all is a stupid idea to do in IE11, which puts me to concern - is this a bug in IE's internal script or I have old version of some file(s) or my PC was compromised ? p.s: this error does not happen on other pages, nor on other elements of JSFiddle site.

  • How to lock Windows7 from installing anything.

    - by Andy
    A family member continually needs me to reinstall his PC after it gets viruses and spyware. He claims that he never downloads anything but evidence suggests otherwise. Unless there is some way that watching 'videos' can get spyware on there. AFAIK the computer is kept up to date. Possible solutions? Make a login where its impossible for him to install anything. Windows 7 standard account doesn't appear to be enough. Is a standard account enough here? I tried this once before and he still seemed to get IE toolbars installed up the wazoo Somehow make an automated image where if he 'messes up' or even on log off the computer restores the whole drive image. Similar to what I've seen in Kinko's Something I've not thought of.... And I know you are all going to say 'stop fixing it you are an enabler'... yes I know but I'm not going to have another fight with my wife over helping her family... right now I'm doing this to keep her happy not the idiot with the 'video' addiction ;-) So the name of the game is minimizing my overhead.

  • What is the fastest MD5 sum calculator?

    - by netvope
    I tested the speed of md5sum on a few Ubuntu 8.04 servers Pentium III 700 MHz: 52 MB/s Atom 1.6 GHz, 32-bit: 119 MB/s Core 2 (Yorkfield) 2.5GHz, 32-bit: 194 MB/s Core 2 (Yorkfield) 2.5GHz, 64-bit: 222 MB/s Then I downloaded a tool (by apt-get install) called md5deep and found that it's roughly 20% faster (as tested on the 32-bit Core 2 server). This makes me feel that the "vanilla" md5sum included in Ubuntu isn't the fastest one. Questions: Other than md5deep, are you aware of any MD5 calculators that are potentially faster than md5sum? (Answers for software from other OS are also welcomed.) If I want to compile md5sum myself, where can I download the source? What compiler options would you suggest for the Core 2 server? (note: gcc 4.2.4 in Ubuntu 8.04 does not seem to support -march=core2)

  • Windows 7 x64 blue screen of death

    I've been running Windows 7 Ultimate x64 on my HP EliteBook 8530w for a few months now, and during that time, it has blue-screen-of-deathed 3 times. This time, I was able to snap a pic with my cellphone before it automatically rebooted: Any idea what might be causing this? Thanks!

  • How to install/upgrade to Windows 8.1 RTM without a Microsoft account

    - by abstrask
    When I installed Windows 8, I deliberately chose not to use a Microsoft account to sign in. I like to keep things separate, and just logon with a tradional local account. Any apps that require me to sign-in with my Live account, will have to prompt me to sign-in. Now, I just updated to 8.1, but towards the end of the setup process, I was asked to sign-in with a Microsoft account or create one. Unlike when installation Windows 8, there didn't seem to be any option to skip that step, or otherwise close the sign-in prompt and continue to my updated Windows installation. At least not that I could find. This is particular annyoing, when setting up computers for friends and family, whom I support. They may not have, or have any interest in getting, a Microsoft account and I'm reluctant to use my own. I realize I can disconnect my Microsoft account after the fact, but is there really no way to install, or upgrade to, Windows 8.1, without being forced to create a Microsoft account? If there is, how does one go a about that?

  • Mircosoft Expressions rejecting FP extensions

    - by Moe
    Hey there, I've just moved to a new server and I can't seem to get FrontPage extensions to work with Mircosoft Expressions. I like to edit my site Live rather then local to server. But Now, when I access my domain.. eg: http://domain.com It'll come up with: Access Denied. And if I click details it returns 501 Method Not Implemented Method Not Implemented GET to / not supported. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. If I define (in .htaccess): ErrorDocument 404 /404.php The Details returns the Title and contents of 404.php. And if I define (in .htaccess): ErrorDocument 404 /404.php ErrorDocument 501 /501.php The Details return nothing. What Am I doing wrong? Thanks.

  • Epson Stylus C84 Won't Print

    - by Chris
    The printer won't print with empty color cartridges. I want to print only black ink. From what I've read so far the Epson Stylus C84 won't print like this because it uses a little bit of color in even when you print only in black to prevent the ink heads from drying out. Is there ANY way that I can bypass this?

  • Is it reasonable to have multiple SSH keys?

    - by Leonid Shevtsov
    So far I've created a separate SSH key for each server I need to login to (for each purpose, to be more accurate). I did it out of a sense of security, just like different passwords to different sites. Does having multiple SSH keys actually improve security? All of them are used from the same machine, are located in the same ~/.ssh, most even have the same passphrase. So... should I give up the whole system and just use one SSH key for everything?

  • How does it hurt to use Linux (Ubuntu) as a guest OS for all my tasks?

    - by sauparna
    I have a machine running Windows, where the disk has two partitions C (50 GB) and D (250GB). I do research in Information Retrieval and need to work with a large corpus (more than 50 GB) and in Linux. So if I want to install Linux on the existing system, keeping the Windows installation intact, will it be fine to run it in a virtual box? (say, QEMU, VMWare, etc.) An alternative is using Wubi. In that case the Linux installation has to be on drive C. Then, if I keep a small Linux installation (say 5GB) on C, and my corpus on D (mounted in Linux), how will it affect the performance of my programs which would be accessing the mounted Windows drive D. Is it feasible to use Linux this way? Which of the above is better if at all they are a way out? Note : Since my post in July 2010, I have been using and have tried several ways of maintaining a disk-image that I can mount in Linux. I had a 100GB qcow2 disk and a 100GB raw disk, both formatted to an EXT3 file system. I was mounting and connecting to the qcow2 disk using qemu-nbd. The problem was that every now and then, the connection to the disk would get lost and the running programs would throw disk I/O errors. The raw disk would mount and work fine as a loop mounted device, but when writing data to it, the mount.ntfs program would hog the CPU and the process would take an enormous amount of time. I was in fact running make on a piece of software located on this raw disk, and after a point of time make was waiting while mount.ntfs would show 100% CPU usage.

  • How to diagnose disk errors when disk appears to be ok?

    - by Kylotan
    I have a six-month-old 1TB Seagate drive formatted into 2 NTFS partitions, and the disk appeared to be failing with Windows dropping down from UDMA to PIO mode, reporting Delayed Write Errors, and hanging Explorer when browsing directories. My initial suspicion was that the disk was dying. However, on further examination it appears that Ubuntu, which doesn't write to the volume frequently like Windows does, was able to read the disk properly and retrieve all the data intact, saving me from having to use an older backup. Finally, running the Seatools DOS diagnostic reported that the disk has no problems, ie. SMART errors and no bad sectors, apparently. This, in combination with the relative youth of the disk, suggests that something else is broken. The cable? The PSU? The integrated disk controller? But what would be a good way to diagnose the problem without risking damaging the data? I intend to extract the disk and try it in an external eSATA enclosure and see if the write errors cease, but in the event of the disk appearing to be fine, I would like to be able to confirm what part of the hardware is actually broken here in order to know just what needs replacing. Are there any good ways to go about this?

  • Blue screen of death while installing any Adobe Air application

    - by Gaurav Sharma
    Whenever I try to install an Air application I get a Blue Screen and then my system restarts. I cannot even take a screenshot of it. This happens with every air application I try to install. I also searched for the same on Adobe forums and found the same problem being faced by someone else. His problem was resolved by uninstalling a software named "Folder Lock". I searched my hard disk for this software and found one, so I deleted that software (shift+delete) and removed all it's traces from registry too but that still doesn't solved the problem. I also tried disabling the antivirus software and then install the air application but this also didn't helped. Here is the screenshot of the BSOD. I was able to install air applications earlier, but now I can't. Anybody having same sort of problem. One colleague of mine is also having the same problem. Please help me out. My system's config is as follows: Windows XP Home sp3 Flash Builder 4, with SDK 4.1, 3.5 installed in it. Adobe Air v 2.5 1.5 GB RAM 1.66 MHz processor Thanks

  • Driverless printer sharing on Windows.

    - by MiffTheFox
    I have a printer hooked up to a computer running Windows XP. It prints fine from that computer, but I'd like to set up other computers (running Vista and 7) to print from it as well. I tried setting up printer sharing, but it wouldn't work because the client computers needed to install the print driver as well. (The driver itself has been discontinued and there's no version for Vista or 7.) Is there some (hopefully free) software I can install to, say, add a virtual printer that sends the data to a host computer to print it, rather then having to directly access the printer over the network via the Windows printer sharing model?

  • Tools to (privately) annotate/markup a website for maintenance

    - by rob
    I've been tasked with updating a website. Rather than proofreading and updating each page (one at a time), I want to make a single pass over the entire website, marking graphics/images/videos that need to be rewritten, removed, or updated. I thought about taking screenshots, marking those up, and putting them in our bug-tracking database, but that seems like an extremely tedious solution. Some of the content is similar on various pages across the website, and the entire site itself is localized into several languages (so any changes made to the English version will have corresponding changes for other languages). I also want all of my markup to remain private (that is, if it's stored online somewhere, I should be the only person who can see my comments). I found an article that lists several website annotation services, but it's not clear whether they allow private annotations, or whether these tools are even appropriate for website maintenance (many of them look more geared toward social networking). I've started making a list of some necessary and desired features below, and may add more as necessary. Annotations/markup/comments remain private (only visible to me) Comment history/tagging (so I can reuse the same comment for shared footers, items requiring similar updates, etc.) Ability to print/export a list or report of all comments for the entire website Ability to produce a categorized list of changes (e.g., to produce a list of images that need updating, which I can send to the graphic designer) What processes and tools do you use to keep track of all the changes that need to be made to a website? What features are painfully absent from the tools you use?

  • Excel - export sheet to fixed-width text file?

    - by jkohlhepp
    I know that Excel has functionality to import fixed-width text files where it presents a dialog that lets you choose where the begins and ends of fields are which it puts into columns. Does it also have functionality where, given an existing spreadsheet, you can export to a fixed-width text file? If so, how do I access this? I have tried using Save As and choosing Text File but it seems to only save as Tab-delimited which doesn't help me. This is Excel 2003 if it matters. Thanks, ~ Justin

  • Get rid of Vista security warning

    - by Ken
    I found this question. The question exactly matches my problem, but the solution doesn't work. In the Properties window, I see "Security: This file came from another computer and might be blocked to help protect this computer. ((Unblock))". When I click Unblock and Apply, the Security section disappears. But when I go to run it again, I still get the security warning. If I right-click and choose Properties on the exact same thing, the Security section is back, offering me the chance to Unblock it again. So unblock seems exactly as useless as the "Always ask" checkbox. Anyone seen this before? How do you really Unblock an app that Vista doesn't want to let you Unblock?
