  • Dell Dimension 2400 problem

    - by murgatroid99
    I have a new problem with a Dell Dimension 2400 PC. Until yesterday or the day before, it was working fine, but today when I press the power button the light on the power button turns yellow instead of green, the fan behind the processor increases speed until it sounds like a jet engine, and the computer does not boot up. I cleaned out the dust in the computer so that is not the problem. Also, the fan was blowing cold air. Do any of you know what might be causing this and how I might be able to fix it?

  • Data Recovery needed with a Sector Zero problem on a HDD

    - by Jay Robins
    Left my computer (running XP) copying files to an external drive. Came back a few hours later, and the laptop was pretty hot and had frozen (Ironic aint it). Forced a reboot, and the laptop HDD hasnt worked since. Set it up in an external enclosure, but XP cant mount the HDD to a drive letter, but is able to recognize the manufacturer and drive size (Hitachi-320GB). No noise or rattling when the drive is spinning, but I cant get anything off of it, since i cant mount it, or see much of anything. Computer repair shop ran some software tests and says it came back with a "Zero Sector bad" message, and need to send it to a professional data recovery service. Any other options or ideas, before I have to spend thousands of dollars to recover my data? Any help would be GREATLY appreciated!!! I'm desperate and a poor student! Thanks in Advance, -Jay

  • dual boot preinstalled windows 8 laptop with windows 7

    - by sarathi
    I am having a hard disk in gpt partition style and Windows 8 is pre-installed in uefi mode. While trying to dual boot using usb bootable disk(using rufus,gpt partition style,fat32),it displays "Windows is loading files", then while displaying "Starting Windows" it hangs. So, I tried to install it inside Windows using setup.exe. Everything was running fine, but when it gets self restarted again, it got stuck at "Starting Windows". When restarted in Windows 8, it showed a htm file stating that "Windows cannot be installed on a computer using battery power. If the battery runs out of power during the installation, you might lose data. To continue the installation, plug in the computer's power adapter." I am sure that power adapter is connected. I Googled a lot on this, but I didn't get solution.

  • nc or socat: How to read data from remote:/dev/ttyACM0 ?

    - by AndreasT
    I have a device running at a remote computer on /dev/ttyACM0 Now I want to read that data on my computer. I can connect to it over ssh. Unfortunately I am a nc/socat rookie and no howto covered this. Semantically like this: cat remote:/dev/ttyACM0 The remote system has a limited linux on it, and I can't install packages. (socat is not available there, nc is) Super cool would be to have some forwarded device: local:/dev/ttySOCK0 pointing to remote:/dev/ttyACM0 Thanks for any help.

    Ever get the desire to control your computer, Star Trek-style? With Windows 7’s Speech Recognition, it’s easier than you might think. Microsoft has been working on its voice command steadily over the years. XP introduced it, Vista smoothed it, and 7 has it polished. It’s strangely not advertised as a feature, even though other voice command and speech recognition programs are hundreds of dollars.

  • How Do I Properly Run OfflineIMAP in a Crontab

    - by alharaka
    Installed Fedora. # cat /etc/redhat_release | awk ' { print F "> " $0; print ""; }' Fedora release 14 (Laughlin) Installed offlineimap from yum, cuz I'm lazy these days. # yum info offlineimap | awk ' { print F "> " $0; print ""; }' Loaded plugins: langpacks, presto, refresh-packagekit Adding en_US to language list Installed Packages Name : offlineimap Arch : noarch Version : 6.2.0 Release : 2.fc14 Size : 611 k Repo : installed From repo : fedora Summary : Powerful IMAP/Maildir synchronization and reader support URL : http://software.complete.org/offlineimap/ License : GPLv2+ Description : OfflineIMAP is a tool to simplify your e-mail reading. With : OfflineIMAP, you can read the same mailbox from multiple : computers.

For instance, you can delete a message on your home : computer, and it will appear deleted on your work computer as : well. OfflineIMAP is also useful if you want to use a mail reader : that does not have IMAP support, has poor IMAP support, or does : not provide disconnected operation. And, lo and behold, every time I run offlineimap and try to redirect output in a crontab, it does not work. Below is my .offlineimaprc.

  • Can't telnet to SQL Server

    - by Thiago
    Hi there, I have an SQL Server running on a computer, and I'm trying to access it from another computer in the same local network (potentially VPN, since it's located in a datacenter). The point is that I can't even telnet to the port in which SQL Server is listening. And yes, SQL Server is working, since I can telnet to it from my workstation. I think it's something in the host, since there's no hop between the two computers, but I don't know how to troubleshoot this. Basically I get a connection failed, when I try to telnet. What can cause such problem, since apparently there's no firewall and the server is accepting connections from other computers? Thanks in advance

  • iPhone 3G S sync services problem

    - by Ryan McCue
    When I try and synchronise my iPhone with iTunes, I get a dialog informing me that "syncing has been disabled on this computer". (I've never disabled syncing myself, and it worked perfectly fine a day ago) Music synchronises fine, as do videos, however, my contacts do not. Google Contacts no longer appears in the list to choose from, and the select box is empty. When I choose to re-enable syncing, iTunes informs me that "iTunes was unable to load provider data from Sync Services". I've followed several steps I've found on the internet, including deleting the C:\Users\Ryan\AppData\Roaming\Apple Computer\Sync Services directory, but to no avail. Any ideas on what could be causing this? Is there a Service (in the Windows-form-of-daemon sense) that I accidentally disabled?

  • Travelling MVP #2: Community event at Bucharest, Romania

    - by DigiMortal
    My second trip was to DevReach with two stops. My first stop was at Bucharest where I met with my friend Dimitar Georgiev who is one of authors of Gym Realm service. Romanian MVP Andrei Ignat was our host there and organized meeting with local community guys. With me – it was first time in my life – was one more guy from Estonia visiting DevReach and he made the whole trip with me. Bucharest We arrived to Bucharest 29.09 at night. We stayed at Hotel Michelangelo. It’s small hotel with nice rooms, free WiFi and very good service. Although my room was on the first floor there was no street noise. We visited one restaurant that offers national cuisine and it was really great. Next day we went out with local guys and had some beers in “old town”. Bucharest “old town” is nice and cozy. There are many bars open and I am sure everybody will find there some very okay place. After supper we visited one warm karaoke bar where we had beers with local guys. Andrei Ignat – karaoke star Agu Suur and Andrei Ion Rinea enjoying karaoke and tequila Community event Next day we had community event. I made my session about ASP.NET Web API and Dimitar told about how to port ASP.NET web applications to cloud environment. Sessions were held at study class of one local company. Dimitar Georgiev speaking about porting web apps to Windows Azure. As it was usual community evening and not some bigger event there were about 12 guys attending from Bucharest. There were both IT-PROs and developers and one nice thing about Bucharest community is that they are listening to you very well and they ask questions if something is unclear or if you slide over from topic they are interested in. Okay, we tried to keep up good tempo so people stay awake and I think we succeeded. After sessions we went all together to local Piranha pub that was near event venue. We had some beers with local guys and talked with them on different technology topics. It was another good and interesting evening at Bucharest. I want to go back there for sure. As it was my first trip to Bucharest and mostly I gathered experiences I think my next community trip there will be way stronger. I take it as a challenge. Plus – I have there some new friends and I want to meet them too – be it community event or not. :)

  • Finding the Twins when Implementing Catmull-Clark subdivision using Half-Edge mesh [migrated]

    - by Ailurus
    Note: The description became a little longer than expected. Do you know a readable implementation of this algorithm using this mesh? Please let me know! I'm trying to implement Catmull-Clark subdivision using Matlab (because later on the results have to be compared with some other stuff already implemented in Matlab). First try was with a Vertex-Face mesh, the algorithm works but it is of course not very efficient (since you need neighbouring information for edges and faces). Therefore, I'm now using a Half-Edge mesh (info), see also the paper of Lutz Kettner. Wikipedia link to the idea behind Catmull-Clark SDV: Wiki. My problem lies in finding the Twin HalfEdges, I'm just not sure how to do this. Below I'm describing my thoughts on the implementation, trying to keep it concise. Half-Edge mesh (using indices to Vertices/HalfEdges/Faces): Vertex (x,y,z,Outgoing_HalfEdge) HalfEdge (HeadVertex (or TailVertex, which one should I use), Next, Face, Twin). Face (HalfEdge) To keep it simple for now, assume that every face is a quadrilateral. The actual mesh is a list of Vertices, HalfEdges and Faces. The new mesh will consist of NewVertices, NewHalfEdges and NewFaces, like this (note: Number_... is the number of ...): NumberNewVertices: Number_Faces + Number_HalfEdges/2 + Number_Vertices NumberNewHalfEdges: 4 * 4 * NumberFaces NumberNewfaces: 4 * NumberFaces Catmull-Clark: Find the FacePoint (centroid) of each Face: --> Just average the x,y,z values of the vertices, save as a NewVertex. Find the EdgePoint of each HalfEdge: --> To prevent duplicates (each HalfEdge has a Twin which would result in the same HalfEdge) --> Only calculate EdgePoints of the HalfEdge which has the lowest index of the Pair. Update old Vertices Ok, now all the new Vertices are calculated (however, their Outgoing_HalfEdge is still unknown). Next step to save the new HalfEdges and Faces. This is the part causing me problems! Loop through each old Face, there are 4 new Faces to be created (because of the quadrilateral assumption) First create the 4 new HalfEdges per New Face, starting at the FacePoint to the Edgepoint Next a new HalfEdge from the EdgePoint to an Updated Vertex Another new one from the Updated Vertex to the next EdgePoint Finally the fourth new HalfEdge from the EdgePoint back to the FacePoint. The HeadVertex of each new HalfEdge is known, the Next HalfEdge too. The Face is also known (since it is the new face you're creating!). Only the Twin HalfEdge is unknown, how should I know this? By the way, while looping through the Vertices of the new Face, assign the Outgoing_HalfEdge to the Vertices. This is probably the place to find out which HalfEdge is the Twin. Finally, after the 4 new HalfEdges are created, save the Face with the HalfVertex index the last newly created HalfVertex. I hope this is clear, if needed I can post my (obviously not-yet-finished) Matlab code.

  • Disk Response Time in Windows 7 Resource Monitor?

    - by Keith Nicholas
    In the resource monitor I'am looking at the disk response time. There are a lot of processes where the response time is thousands of milliseconds consistently, I'm pretty sure this is the source of my computer slowing down. I'm not sure what normal response times are though? I'm running win 7 64bit ultimate. This is running on a new computer, i5 with a terabyte drive, 4gigs of ram, etc, disk is still pretty much empty, so it should all be pretty snappy. And if it is going really slow, how do I track down whats causing it? I've turned off things like real time virus protection as experiments to see if there is something weird there, but makes no real difference (other than it doesn't contribute to the problem by accessing the disk)

  • How do I get fan control working?

    - by RobinJ
    I know there something called fancontrol, that enables you to control the speed of your system's ventilation. I'd like to let my fans spin a bit faster as my laptop is heating up very easilly. All tutorials and stuff I've found are for old versions of Ubuntu and don't seem to be working anymore. Can anyone explain to me or give me a good link on how I can get it working on Ubuntu? Something different with the same effect is also fine.

  • Sharepoint Server 2007 generates event log entry every 5 minutes - "The SSP Timer Job Distribution L

    - by Teevus
    I get the following error logged into the Event Log every 5 minutes: The SSP Timer Job Distribution List Import Job was not run. Reason: Logon failure: the user has not been granted the requested logon type at this computer In addition, OWSTimer.exe periodically gets into a state where its consuming almost all the CPU and only killing the process or restarting the Sharepoint services fixes it (although I'm not sure if this is a related or seperate issue). I have tried the following (based on various suggestions floating around the web), all to no avail: iisreset (no affect) Added the Sharepoint and Sharepoint Search service accounts to Log on as a batch job and Log on as a service policies in the Group Policies for the domain. I went into the Local Computer Policy on the Sharepoint server and verified that those policies had actually been applied Verified that the Sharepoint and Sharepoint Search service accounts are both in the WSS_WPG group Verified in dcomcnfg that the WSS_WPG group (and indeed the Sharepoint and Sharepoint search service accounts) has local activation rights for SPSearch. Any more suggestions would be valued. Thanks

  • Linux to Solaris @ Morgan Stanley

    - by mgerdts
    I came across this blog entry and the accompanying presentation by Robert Milkoski about his experience switching from Linux to Oracle Solaris 11 for a distributed OpenAFS file serving environment at Morgan Stanley. If you are an IT manager, the presentation will show you: Running Solaris with a support contract can cost less than running Linux (even without a support contract) because of technical advantages of Solaris. IT departments can benefit from hiring computer scientists into Systems Programmer or similar roles.  Their computer science background should be nurtured so that they can continue to deliver value (savings and opportunity) to the business as technology advances. If you are a sysadmin, developer, or somewhere in between, the presentation will show you: A presentation that explains your technical analysis can be very influential. Learning and using the non-default options of an OS can make all the difference as to whether one OS is better suited than another.  For example, see the graphs on slides 3 - 5.  The ZFS default is to not use compression. When trying to convince those that hold the purse strings that your technical direction should be taken, the financial impact can be the part that closes the deal.  See slides 6, 9, and 10.  Sometimes reducing rack space requirements can be the biggest impact because it may stave off or completely eliminate the need for facilities growth. DTrace can be used to shine light on performance problems that may be suspected but not diagnosed.  It is quite likely that these problems have existed in OpenAFS for a decade or more.  DTrace made diagnosis possible. DTrace can be used to create performance analysis tools without modifying the source of software that is under analysis.  See slides 29 - 32. Microstate accounting, visible in the prstat output on slide 37 can be used to quickly draw focus to problem areas that affect CPU saturation.  Note that prstat without -m gives a time-decayed moving average that is not nearly as useful. Instruction level probes (slides 33 - 34) are a super-easy way to identify which part of a function is hot.

    I'm re-writing an old virtual world/browser based game. It is text and HTML form based with some static graphics. The client is HTML and JS. I want to introduce some interactive graphical elements to certain parts of the game, for example a 'customise character' page, with hooks to server side and local data storage. I want to use HTML5/JS, what is the best approach to designing the web-site? For example could I use Boilerplate and then embed these interactive elements in the page? Thanks

  • Ask the Readers: Do You Use the Command Line?

    - by Jason Fitzpatrick
    Despite over two decades of GUI interfaces many power users still turn to the command prompt. This week we want to hear about when and how you use the command prompt on your computer. Long ago in a time before you could manipulate your computer with a mouse and a series of buttons and windows, the command line ruled all. Even after years of GUI development and refinement many people still turn to the command line to get things done. This week we want to hear all about your command line tips and tricks. Do you use the default command line for your OS? Have you enhanced it? Replaced it? What keeps you coming back to the command line when everyone happily works away in the OS’s GUI?

    I would like to buy a computer for Rendering purpose. The Rendering is based on DirectX in Windows 7. It needed to support multi-thread rendering which is highly demanding (around 20 threads doing rendering and connection to MS SQL Server job simultaneously). Could I have some suggestion on the configuration of the computer? e.g. what kind of CPU, GPU, Mother Board should be used? The budget is around US$1000. Thank you very much.
