  • LAN speeds and firewall/switch connections

    - by microchasm
    I have a small network with about ten users. All workstations flow into a Dell PowerConnect 3424 which then has a single link to a SonicWALL firewall and from there to a cable modem. More important than internet connectivity is speed between machines (specifically a Windows Server box on the LAN which everyone uses simultaneously). I believe the 3424 has gigabit connections, but they look like they're for stacking. Is there a way to test the speeds on the LAN to see where the speeds are at? Is there any low-hanging fruit insofar as increasing speeds?

  • What type of SATA cable will I buy?

    - by Mehper C. Palavuzlar
    I've bought a new optical drive. It's a Samsung SH-S223C with SATA connection. Since it is OEM with no box, no cable came with it, so I need two cables now. Since I have an extra SATA power cable, it's OK, but I have to buy the data cable. What type of cable should I buy? If you please give a picture of it besides its type as well, I'll be happy. My motherboard is GigaByte P43-ES3G. TIA.

  • Mac keeps switching to second graphics card

    - by 1.21 gigawatts
    I have a MacBook Pro and whenever I enter certain apps (video camera app or Photoshop for example, the graphics card switched. I didn't know this was going on at first; just that the screen kept changing colors as I opened or closed different software. Later someone told me that the software was causing the OSX to switch graphics cards. It's annoying. How do I keep one graphics card (the better one) enabled all the time? I don't care about power consumption because it is plugged in all the time (though I'm curious how much difference it makes). I just want one graphics card enabled.

  • subset in geom_point SOMETIMES returns full dataset, instead of none.

    - by Andreas
    I ask the following in the hope that someone might come up with a generic description about the problem.Basically I have no idea whats wrong with my code. When I run the code below, plot nr. 8 turns out wrong. Specifically the subset in geom_point does not work the way it should. (update: With plot nr. 8 the whole dataset is plottet, instead of only the subset). If somebody can tell me what the problem is, I'll update this post.

  • How can I convert videos for Sony Xperia U on my Linux box?

    - by Konstantin
    I would like to send a few videos for my girlfriend, but I would ensure they are playable on her mobile phone. I want to carry out the encoding tasks on my Arch Linux box, because my PC is a low end. I can use only ffmpeg or mencoder or other CLI tool. She can play youtube videos but I don't want to upload such videos to youtube. Are there any presets for specific mobile phones? And when she simply clicks a video direct link will it play directly on the cellphone or should I embed it in a html5 / flash player, like on youtube?

  • DSP - Filtering in the frequency domain via FFT

    - by Trap
    I've been playing around a little with the Exocortex implementation of the FFT, but I'm having some problems. Whenever I modify the amplitudes of the frequency bins before calling the iFFT the resulting signal contains some clicks and pops, especially when low frequencies are present in the signal (like drums or basses). However, this does not happen if I attenuate all the bins by the same factor. Let me put an example of the output buffer of a 4-sample FFT: // Bin 0 (DC) FFTOut[0] = 0.0000610351563 FFTOut[1] = 0.0 // Bin 1 FFTOut[2] = 0.000331878662 FFTOut[3] = 0.000629425049 // Bin 2 FFTOut[4] = -0.0000381469727 FFTOut[5] = 0.0 // Bin 3, this is the first and only negative frequency bin. FFTOut[6] = 0.000331878662 FFTOut[7] = -0.000629425049 The output is composed of pairs of floats, each representing the real and imaginay parts of a single bin. So, bin 0 (array indexes 0, 1) would represent the real and imaginary parts of the DC frequency. As you can see, bins 1 and 3 both have the same values, (except for the sign of the Im part), so I guess bin 3 is the first negative frequency, and finally indexes (4, 5) would be the last positive frequency bin. Then to attenuate the frequency bin 1 this is what I do: // Attenuate the 'positive' bin FFTOut[2] *= 0.5; FFTOut[3] *= 0.5; // Attenuate its corresponding negative bin. FFTOut[6] *= 0.5; FFTOut[7] *= 0.5; For the actual tests I'm using a 1024-length FFT and I always provide all the samples so no 0-padding is needed. // Attenuate var halfSize = fftWindowLength / 2; float leftFreq = 0f; float rightFreq = 22050f; for( var c = 1; c < halfSize; c++ ) { var freq = c * (44100d / halfSize); // Calc. positive and negative frequency indexes. var k = c * 2; var nk = (fftWindowLength - c) * 2; // This kind of attenuation corresponds to a high-pass filter. // The attenuation at the transition band is linearly applied, could // this be the cause of the distortion of low frequencies? var attn = (freq < leftFreq) ? 0 : (freq < rightFreq) ? ((freq - leftFreq) / (rightFreq - leftFreq)) : 1; // Attenuate positive and negative bins. mFFTOut[ k ] *= (float)attn; mFFTOut[ k + 1 ] *= (float)attn; mFFTOut[ nk ] *= (float)attn; mFFTOut[ nk + 1 ] *= (float)attn; } Obviously I'm doing something wrong but can't figure out what. I don't want to use the FFT output as a means to generate a set of FIR coefficients since I'm trying to implement a very basic dynamic equalizer. What's the correct way to filter in the frequency domain? what I'm missing? Thanks in advance.

  • Laptop VGA Output Stopped Working

    - by Jack7890
    I regularly use an external monitor with my laptop. Today, when I booted up, the external monitor refused to work--it just keeps going into power save mode. I tried a different external monitor and had the same problem, so it must be a problem with the laptop itself. Things I've tried: Going into the Display Settings via the Control Panel (I'm running Vista) and attaching/unattaching/reattaching the external monitor. Turning the computer off, unplugging, plugging it back in, and rebooting Blowing into the VGA out to get rid of any dust Toggling through the Fn+F7 options I'm thinking maybe this is an issue with my video card? If necessary, I'm comfortable opening up my laptop and playing around with things, but I'm not sure what to look for. Does anyone have any suggestions?

  • windows vms unpredictibly require login

    - by marrrkus
    I have a cluster of vms on a number of cloned servers using libvirt/qemu. Occassionally the windows 7 vms randomly require a login screen, even though I've done everything I can think of and can google to turn off a login screen. I've used netplwiz to turn off requiring a password (http://pcsupport.about.com/od/windows7/ht/auto-logon-windows-7.htm) manually changed the regsistry using the instructions here: http://superuser.com/a/28654 changed requiring a password in the power saving settings in the control panel if the screen goes to sleep told the screen to never go to sleep (in the control panel) Even with all of these things, some of the vms *still* randomly require a login. I have no idea what else to try. Any ideas??

  • What is the Best Free Linux Gateway

    - by rockinthesixstring
    I'm looking at moving away from using my DIR-825 as a gateway and moving into a Linux box to do it all for me. I've found IPCop, but I'm looking for something with a little more power. My main goal is basically to be able to point different external domain names to different internal servers. backup.example.com - 192.168.0.5 home.example.com - 192.168.0.1 I host my DNS on my own dedicated server (windows), so I don't know much about doing the gateway thing in my home (my hosting provider does it all for me). Do any of you know of any free Linux Distros that can accomplish what I'm looking for?

  • Computer froze up

    - by Arlen Beiler
    Why would my computer freeze up out of the blue? I have Apache Webserver w/php, and MySQL server installed. I am not sure exactly when it happened, but I was doing something on a wordpress site that I have installed, and it just waited and waited and waited. Then, all the folders on it that were open on my other computer closed, as though I had disconnected it. Then the skype account went offline. The computer was totally froze. I thought maybe it was someone on logmein, but disconnecting it from the network didn't do anything. I had to "crash" it (held in the power button till it shutdown). It started up normally then and the logs showed absolutely nothing wrong. And doing the same thing that I did when it froze didn't repeat the freeze. Any ideas, I never had this happen before.

  • how to use ggplot conditional on data

Any help that will get me started is much appreciated. Thanks in advance.

  • Full Backup & Restore for Windows Vista

    - by Thomas Matthews
    I'm looking for a freeware or low cost application that will backup everything, including registry on Windows Vista Home Premium and to restore from a CDROM disk. The destination is an external hard drive on USB 2.0. Searching on SuperUser and Stack Overflow show articles, but don't mention full backup of the registry and complete restore using CDROM. I would also like to have compressed output and incremental backups. One article mentions CloneZilla, but their web page says that the incremental feature is not supported. I am using Windows Vista Home Premium, Service Pack 1. I need to backup 200 GB onto a 230 GB drive and would like to have multiple backups (thus the need for compression). Other requirements: Single file restore Quality is more important than performance. Application must run on Windows Vista. Extra: Run as daemon or background task on 4 user system. Thanks

  • 912 stream processor available in OpenCL

    - by tugrul büyükisik
    I am thinking of assembling this system: AMD CPU (A8-3870 APU which has Radeon HD 6550D inside: 400 stream processors:xxx GFLOPS) nearly 110$ AMD Graphics card: HD 7750 (512 stream processors:819 GFLOPS peak performance) nearly 170$ Appropriate ram (1600MHz bus) Mainboard What GFLOPS level can I reach as a stable mode with using OpenCL and similar programs? Can I use all 912 stream processors at the same time? I am not trying to do a VS question. I need to know what could be better for scientific computing (%75 of the time) and gaming (%25 of the time) because I have a low budget. With "scientific calculations" I mean fluid dynamics/solid state physics simulating; with games I mean those that need openCL and PhysX.

  • Suggestions for Troubleshooting WIndows 7 lockups

    - by Craig L
    I've got a Dell Latitude E6500 that was working fine under Vista x64. I got one of the new Seagate 500GB Hybrid SSD/HD 2.5 drives and thought.. hmm.. let's try Win 7 x64 on it. Bottom line: It works great for hours and then it will hard lock. I don't mean BSOD (or whatever the Win7 equivalent is). I mean my screen is displaying a static image (if there is a clock displayed, it will be frozen at the time the lockup occurred) and the mouse and keyboard do not work. Control-Alt-Delete will not work. I have to hold down the power button to reboot. The event log records NOTHING at the time the lockup occurs. Obviously something is happening to the system to cause the lockup, but the default Windows 7 x64 doesn't log it. How can I log the things Windows doesn't normally log in Event Viewer ?

  • Laptop VGA Out Stopped Working

    - by Jack7890
    I regularly use an external monitor with my laptop. Today, when I booted up, the external monitor refused to work--it just keeps going into power save mode. I tried a different external monitor and had the same problem, so it must be a problem with the laptop itself. Things I've tried: Going into the Display Settings via the Control Panel (I'm running Vista) and attaching/unattaching/reattaching the external monitor. Turning the computer off, unplugging, plugging it back in, and rebooting Blowing into the VGA out to get rid of any dust Toggling through the Fn+F7 options I'm thinking maybe this is an issue with my video card? If necessary, I'm comfortable opening up my laptop and playing around with things, but I'm not sure what to look for. Does anyone have any suggestions?

  • Dell U271 monitor DisplayPort suddenly not working

    - by Amir Latif
    My new(ish) Dell U271 took a bit of a knock and it now suddenly doesn't recognise the Macbook plugged into it via DisplayPort - this had been working great for several months up until now. When I "Scan Sources", it doesn't find anything on DisplayPort. However, one suspicious behaviour leads me to think all might not be lost. When the Mac is woken from sleep, this used to kick the monitor in (as an monitor would) and while it no longer does that, the light on the monitor does go from standby orange to blue briefly, then the monitor says it's going into "power save" mode. It seems like it gets some kinda signal. Any ideas on how I can diagnose the problem? I'm trying to find another mac but no one near me has one ...

  • Unmounted root partition

    - by Jack
    My server running Debian lenny has just had a power cut recently and its come back up with the root partition in read only mode. I tried to remount the filesystem in read write mode with mount -n -o remount,rw / which then gave the output mount: block device /dev/hda1 is write-protected, mounting read-only. But now the root filesystem isn't mounted at all so I can't run anything to mount the partition again or any other command for that matter such as shutdown because /bin/ isn't there. Is there anything I can do remotely?

  • Python multithreading not working on VPS server

    - by Sabirul Mostofa
    I am running an python multithreaded application with multiple processes which scrapes data from some websites. While running on my localhost It works great, but on the vps server I am using( Centos 5.8, 2.6 GHZ with 4 cores) performs very slow. From the nethogs command I get the network usage too low. I get around 8KBps with 15 threads. On other hand, in my PC I get the usage around 100-120KBPS. I have read about the Python GIL and threading limitations. It seems GIL never releases the lock on the VPS though it should while doing I/0 Is there any configuration in the VPS that I need to change for the threading to work properly?

  • How do I get 480i resolution for an external monitor in Windows 7?

    - by Carson Myers
    I'm trying to get a laptop video signal to my really old television, so that I can play movies on it. But the TV won't accept the video signal. I found the manual online, and apparently the output has to be 480i. But I don't know how to do that -- Windows 7 will only let me set the resolution down to 800x600. Even if I get it down to 640x480- is that 480i or 480p? How do I tell the difference? How do I switch between them? How do I get the resolution down so low in the first place?

  • Copying Metadata Between Files in iTunes

    - by Levi Hackwith
    A while back, I converted some AVI files to .m4v files that would be playable on my iPhone. When I play these files on my PC using iTunes the quality is terrible because the resolution is so low. My solution is to convert the AVI's using Handbrake using the "Universal" preset; it works like a charm and I can now watch them both on my PC and iPhone. The Problem I want to import the newly converted files into my iTunes library and be able to copy the metadata (show, season (these are TV episodes) Description, etc) without having to manually copy and paste values from one file to another. Is it possible to just say "copy this file's metadata to this file"?

  • Scripts under pm/sleep.d are not getting called when suspending with KDE 4.3

    - by Richard Corden
    Fujitsu-Siemens H240, Slackware-current, KDE 4.3.2. I would like to perform some additional steps when my laptop suspends. I found this SU question which is very close to what I am asking, however the scripts that I placed in that directory are not being called for me. This could be a Slackware thing, or its possible that KDE has a different location for these scripts. I am suspending by using the "Suspend" radio button on the "Guidance Power Manager" dialog of KDE. Is there a standard location where I can place my scripts so they'll be run before and then after the machine has suspended?

  • Multiple servers acting like a single one with all the hardware?

    - by marc.riera
    Hello, by now I have 10 servers for hpc, power computing oriented. My users need to launch several processes using qmake. The users are used to work with ubuntu 9.10, and the software from the repositories is switable for them. I've deployed ubuntu 9.10 to all 10 servers (pxe rocks). By now we work with parallel-ssh and cluster-ssh, which allows as to launch the same process to all servers. With this tools this tools the servers remain as independent but with the same software and the same launched command. Now we would like to go to next step and see all the servers as a single one with all the resources from the other 9 as if was its resources. The difference would be substantial in time to process and also time to design the command to launch. Any advice on wich software to use will be very useful? Thanks

  • Why doesn't my Droid phone charge when connected to a powered USB hub that is not connected to my computer?

    - by pkaeding
    I notice that my new Motorola Droid phone charges perfectly fine when I connect it to my computer via the USB cable, or if I connect it to a car cigarette lighter-USB adapter, or a wall power-USB adapter. It also works fine when I connect it to a powered USB hub that is connected to my computer. However, if that same powered USB hub is not connected to my computer when I connect the phone, it does not charge. If I connect the computer to the hub, and then connect the phone to the hub, it will charge. If I then disconnect the computer from the hub, the phone will continue to charge. Does anyone know why this is happening, or what I can do to be able to charge my phone from a powered hub, without my computer being present?

  • Printer Problems: Snow Leopard with Epson CX 4200 - worked and then didn't?

    - by user33521
    We got a new laptop in the office with Snow Leopard. We installed the new driver for the Epson CX 4200 printer we have and it seemed to be working okay. However, after an Apple update, the printer stopped working. A few days later we saw an update for the Epson driver and so we downloaded and installed that. However, the printer still isn't working. We plugged and unplugged the printer power cable and usb cable, and also tried replacing the ink (because the colour ink light was blinking)...however the printer still isn't working?

  • MacBook says to replace battery. Should I?

    - by Palantir
    Hi! My MacBook says that battery is not charging, and the battery is completely empty (in fact, pressing the button on the battery illuminates no LEDs). If I plug the power adapter off the mac shuts off immediately. I tried with a spare adapter, and it won't charge it. System information says it has 380 cycles. The battery is 2.5 years old. System profiler says the battery has 0 mAh of capacity, and that it should be replaced. Should I just buy a new battery, or should I bring it to an apple point, and leave it there? They can take a look at it (it's on AppleCare), they told me that they will repair it is there is anything wrong with the charging circuit, but they won't give me a new battery. They will keep the laptop for 10 working days at least... I hate when this happens :P
