  • Can Perforce backup files?

    - by Macca
    From reading the Perforce docs it sounds like only changelists and version history can be backed up. Is it possible to get Perforce to create a backup of files too, so that in the event of loss, through hardware failure for example, a complete set of files could be recovered?

    - by Pydev UA
    I'm looking for solution for a public wifi spot.. I want that all people who connect to our wifi network should be redirected to special website(after they open any internet page) where they should reed and agree with our terms of services(by clicking a button). After that they can open any internet page. I have a router and a linux box with site(with agreement page ready), so I'm looking for some software/or hardware solution for this, preferable open-source.

  • Are there any advantages to using windows 7 ultimate? I can't tell the diference

    - by Jack Dawson
    I just upgraded my new desktop which came installed with Windows 7 Home Premium 64 bit with a copy of Windows 7 Ultimate 64 bit and so far I have not noticed any difference in performance. Even my Windows Experience Index number is the same 5.5 that it was before the upgrade. So what's the point, are there any performance advantages that I'm not seeing? Additional Info My system hardware specs: AMD quad core 2.6 GHZ 1 TB 4200 RPM HDD 8 GB DDR2 RAM ATI Radeon HD 4650 w/ 1GB dedicated video memory

  • FFMPEG: how to add watermark to video?

    - by DocWiki
    My Platform: Ubuntu 10.10 + FFMPEG 0.5.3(I installed ffmpeg from source) I try to add Watermark to a .MOV video with FFMPEG 0.5.3 imlib2.so (Please note FFMPEG 0.6+ dont support imlib2.so, so I use ffmpeg 0.5.3) Here is my code: ffmpeg -sameq -i example.mov -vhook '/usr/local/lib/vhook/imlib2.so -x 0 -y 0 -i /var/www/files/watermark.png' newexample.mov Here is the output: FFmpeg version 0.5.3, Copyright (c) 2000-2009 Fabrice Bellard, et al. configuration: --enable-avfilter --enable-filter=movie --enable-avfilter-lavf libavutil 49.15. 0 / 49.15. 0 libavcodec 52.20. 1 / 52.20. 1 libavformat 52.31. 0 / 52.31. 0 libavdevice 52. 1. 0 / 52. 1. 0 libavfilter 0. 4. 0 / 0. 4. 0 built on Jul 3 2011 12:05:08, gcc: 4.4.5 Seems stream 1 codec frame rate differs from container frame rate: 59.94 (5994/100) - 29.97 (30000/1001) Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'example.mov': Duration: 00:03:14.06, start: 0.000000, bitrate: 3350 kb/s Stream #0.0(eng): Audio: aac, 48000 Hz, stereo, s16 Stream #0.1(eng): Video: h264, yuv420p, 1150x647, 29.97 tbr, 29.97 tbn, 59.94 tbc Output #0, mov, to 'newexample.mov': Stream #0.0(eng): Video: mpeg4, yuv420p, 1150x647, q=2-31, 200 kb/s, 90k tbn, 29.97 tbc Stream #0.1(eng): Audio: 0x0000, 48000 Hz, stereo, s16, 64 kb/s Stream mapping: Stream #0.1 - #0.0 Stream #0.0 - #0.1 Unsupported codec for output stream #0.1 What could be the possible problem?

HOWTO: Install and use the latest FFmpeg and x264 or there is a simpler solution?

  • How do I combine static and dynamic DHCP leases on a Cisco router?

    - by Brad
    Basically, what I need is super similar to the unanswered cisco forum question below: https://supportforums.cisco.com/message/3139749#3139749 I have a Cisco 850 Series router. I have configured a DHCP pool for the 10.0.0.0/24 network. I have excluded 10.0.0.1 - 10.0.0.99 from the DHCP pool. I want to add a static DHCP pool for stuff and I want DHCP to statically assign them the addresses of my choice below 100. Actually, I don't care what addresses I statically assign. They can be anything in the pool for all I care, I just want it to work. Why are you doing this? Just statically assign the IPs on the devices! I don't want to do this because I have some laptop users. They could obviously only use that static IP here. This isn't a problem if they could be bothered to change any location setting or something. They can't. So it HAS to be DHCP. It also has to be static IPs because I need to forward ports to them. I know, I know, this is weird but it's an apartment LAN/WLAN so this isn't exactly a typical use case. Relevant sections of config below: ip dhcp excluded-address 10.0.0.1 10.0.0.99 ! ip dhcp pool Internal-net import all network 10.0.0.0 255.255.255.0 default-router 10.0.0.1 domain-name 1770.local lease 7 ! ip dhcp pool static-pool import all origin file flash://staticmap default-router 10.0.0.1 domain-name 1770.local Contents of staticmap: *time* Aug 5 2010 09:00 AM *version* 2 !IP address Type Hardware address Lease expiration 10.0.0.100/24 1 001f.5b3e.d50a Infinite *end* You can see here I was trying addresses outside the excluded-address range to see if that would make any difference. My testing machine's MAC: mainframe:~ brad$ ifconfig en1 en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether 00:1f:5b:3e:d5:0a What shows up in the DHCP binding table: basestar#show ip dhcp binding Bindings from all pools not associated with VRF: IP address Client-ID/ Lease expiration Type Hardware address/ User name 10.0.0.112 0100.1f5b.3ed5.0a Aug 12 2010 10:06 AM Automatic What's up with the funny looking MAC in the DHCP binding table?? Is what I'm trying to accomplish basically impossible? Am I going about this the wrong way? All I want to to be able to port forward some ports to specific devices. The way I would do this with a consumer router is to do what I'm trying to do here; assign static DHCP to those devices then configure PAT for ports on those addresses.

  • Video memory buswidth vs video memory Bandwidth

    - by Mixxiphoid
    My current video card (9600GT) is dying and I'm searching for a new video card. Between acquiring my current one and now, I got a lot more knowledge about hardware and I want to use that to pick my new card. So I decided to not just buy some popular card blindly, but to search for a card able to handle my hardware requirements. I searched the specs at the NVidia site for the GT640 and was confused by the memory section and some questions raised. My current card's memory bus width is 256bit and has 1GB of memory. I checked Google about the importance of bus width. And all the links basically said the same 'The higher the number the more potential simultaneously traffic can be transferred'. This was already clear to me, yet there are currently a lot of new cards which are considered better than my current one with a lower bus width. To go in more detail about my question I copied the memory info from the NVidia site: GT 640 GT640 GDDR5 Memory Specs: Memory Clock 1.8 Gbps 5.0 Gbps Standard Memory Config 2048 MB 1024 MB Memory Interface DDR3 GDDR5 Memory Interface Width 128-bit 64-bit Memory Bandwidth (GB/sec) 28.5 40.0 What puzzled me is that the Memory Bandwidth seems to me the most important part, yet the lower bus width has the higher 'performance'. Is this due to the fact the memory interface is GDDR5 and is therefore able to have a higher memory clock speed (5Gbps)? If I am to buy a new video card, should I check the bus width? Memory clock? Bandwith? Amount of memory? My current card ahs 1GB memory, so I was searching for a 2GB memory card, but now I'm not so sure any more whether that is really 'better'. My main question: To me it seems that memory performance is made up by the combination of bus width and frequency. Is this true? If yes, why are there so many sites telling me I need to get a card with a high bus width? If no, then what IS important when it goes about memory performance on a video card. NOTE: The memory bandwidth is (almost) never displayed on vendor sites. How can I determine which card is better without knowing the bandwith?

  • Where can I get Windows XP Images for WMware Workstation

    - by Saif Bechan
    Does anyone know where I can get windows images for vmware. I know Microsoft gives away the images for Virtual PC. These images work pretty well, but when I try to import them in VMware I need to activate the copies again, because the virtual hardware they use is just to different. I want Images of different versions of windows 2000, xp, vista. Does anyone where I can download them, or do I need to build them from CD.

  • Tool that will virtualize BIOS

    - by Nrew
    Is there any application that can virtualize the BIOS?So that you can see the effects of what the changes in the setting of your BIOS. I know that there are many versions of BIOS depending on your hardware. But is it possible to copy it and then virtualize it when you are running your system. So that you can see if your system can still run after changing the settings.

  • Epson Artisan 800 on Ubuntu/Linux

    - by Tim Lytle
    Update for Ubuntu 10.04: Printing should work 'out-of-box', scanning still needs the newer sane backend. Looking for a known good way to setup an Epson Artisan 800 on Ubuntu specifically or any linux box in general. It is a printer/scanner with ethernet/wifi/usb. I'd like to use it as a network printer/scanner being able to do both from my Windows and Ubuntu machines; however, if it needs to be physically connected to a computer (preferably the Ubuntu machine) that is doable (again, then sharing print/scan functions to the network). Basically, I'm looking for someone who has used this printer/scanner (or similar) in a multi-platform environment to share how the set it up and how well it worked. Updated: A little more information, like most printers (I expect) the documentation for the printer basically says, "don't use plug-n-play, run our setup CD from your Windows/Mac system", to do anything (set it up for network use even). I guess that's to make it easy for anyone else to setup, but when you're looking to use it with an unsupported (by Epson's documentation) OS, you're just stuck on your own. What I was hoping for was someone who could say, "Forget the bundled software, do [this] to set it up on wifi manually, install [this] to connect to the scanner from [os], printing works with [this] driver - at least that's how I set it up." I'll will (and have so far) use the information here, and post my own setup when I'm done, if there's no one else out there with that experience.

  • Make isolinux 4.0.3 chainload itself

    - by chainloader
    I have a bootable iso which boots into isolinux 4.0.3 and I want to make it chainload itself (my actual goal is to chainload isolinux.bin v4.0.1-debian, which should start up the Ubuntu10.10 Live CD, but for now I just want to make it chainload itself). I can't get isolinux to chainload any isolinux.bin, no matter what version. It either freezes or shows a "checksum error" message. I'm using VMWare to test the iso. Things I have tried: .com32 /boot/isolinux/chain.c32 /boot/isolinux/isolinux-debug.bin (chainload self) this shows Loading the boot file... Booting... ISOLINUX 4.03 2010-10-22 Copyright (C) 1994-2010 H. Peter Anvin et al isolinux: Starting up, DL = 9F isolinux: Loaded spec packet OK, drive = 9F isolinux: Main image LBA = 53F00100 ...and the machine freezes. Then I've tried this (chainload GRUB4DOS 0.4.5b) chainloader /boot/isolinux/isolinux-debug.bin Result: Error 13: Invalid or unsupported executable format Next try: (chainload GRUB4DOS 0.4.5b) chainloader --force /boot/isolinux/isolinux-debug.bin boot Result: ISOLINUX 4.03 2010-10-22 Copyright (C) 1994-2010 H.

  • External USB HD issues with a twist (works on Windows7 but not XP)

    - by Eruditass
    I have this older external USB HD, 160 GB. I was using it to copy my Steam games to another computer. On the source computer, Windows 7 64-bit, everything worked fine. Drive reported no errors, had no hiccups, etc. Plugging it into the Windows XP 32-bit computer, it worked fine for looking through the files, moving files around on it (no real reading/writing, just modifying the filesystem table). However, when copying files from it to my internal HD, after a couple seconds to tens of minutes (seemingly random times), the USB device becomes unrecognized and it reports a delayed write error. Events in system log go like this, chronologically: (number times displayed)xSource (Event ID): "message" 2xdisk (51): An error was detected on device \Device\Harddisk1\D during a paging operation. 1xftdisk (57): The system failed to flush data to the transaction log. Corruption may occur. 1xApplication popup (26): Windows - Delayed Write Failed : Windows was unable to save all the data for the file E:\$Mft. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. 1xntfs (50): {Delayed Write Failed} Windows was unable to save all the data for the file . The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. These repeat for a while, then there is 10+ disk messages or ftdisk messages. Other notes: This occurs on random files at random times. This problem cannot be replicated on the Windows 7 source machine when copying from the HD to a different location on its local disk chkdsk /f was run and found no errors. chkdsk /f/r has the delayed write issue. drive was set to quick removal. Setting to performance in device manager yielded same result I am not writing anything to the USB external drive, so I am not sure why there is even a delayed write error (writing file access times?) local Windows XP was chkdsk'd without problems Windows XP machine has no problems with other USB HD's Various USB ports were attempted Rebooting did not help Occurs with SyncToy as well as windows explorer SMART status is good on both local drive and the external one Lack of gaming is making me cranky

  • 3 Servers, 2 Work Fine, One Has Network Issues

    - by ScaleOvenStove
    i have 3 servers, all relatively the same hardware/config, etc. I run some data pulls on all 3, and on 2 of them, they have 1 nic, and they work fine. On the other , there are 2 nics, and unless they are both plugged in or teamed, the processes time out. Any ideas on why this would be? It doesn't make sense to me, as the other two work fine with 1 nic and don't time out when running the same processes.

  • HDD from Mid-2009 MacBook Pro works OUTSIDE laptop, but not INSIDE.

    - by Jaime
    Leading up to the problem: I was working late one night on a Keynote presentation. My battery ran out, and the computer did that hibernation thing it does when there's no battery power. I got my charger, connected it to my computer, and then pushed the power button. It started up for a second in to the gray screen it usually goes to. Then I turned around, tugging the magsafe charger out of the connector on the computer. This caused my computer to shut down again. Now I can't get it to boot at all -- just a blinking folder icon with a question mark in it on boot up. I've tried pretty much everything to deal with this. Multiple forced reboots, resetting PRAM and NVRAM, etc. I booted to original OSX disc and ran disc utility, but I discovered that there is no disc to boot to. I ran the Apple Hardware Test, and it came back 100% good. I booted to an Ubuntu live-boot disc and ran that disc utility, just to see if it recognized a disc at all. It didn't. So I removed the HDD, and replaced it with a bootable volume running BSD. It didn't recognize that HDD either. I then attached my HDD to my computer via an external enclosure with a USB interface. Lo and behold, it booted! So my computer now only work with my HDD attached externally. This means that the HDD is functional. And the AHT returns no hardware malfunctions. So what the hell is going on? … In the meantime: I've put the HDD back into the computer but it still doesn't do anything at all (I'm running it externally right now). I just checked the serial number and my 1 year warranty expired recently, so I can't send it back for repair. … Little Help Thoughts? I've been searching everywhere for leads, but no luck. …

  • Lucid Lynx login issue

    - by Bart Silverstrim
    Recently upgraded from Karmic to Lynx. Upgrade seemed to go well, no noticeable issues. I logged in, and my window manager wasn't starting. An application would appear, but sans control buttons and border, so figured the windows manager needed to be given a swift kick. Opened a web browser and a quick google had me run "metacity --replace &" and everything popped up. I re-ran the Compiz configuration tool to enable my rotating desktop cube to the way I liked it, and had to reconfigure my desktop switcher to the right number of desktops (although the first time I ran it, it crashed on the panel and reloaded...odd, but once it relaunched it seemed fine.) Today I installed updates, rebooted and logged in for the second time since my upgrade. Again, the window manager was dead, and my compiz settings were gone, and the workspaces were set back to four (and when I clicked on the preferences to change them, it crashed on the panel and reloaded again). Resetting everything made things look somewhat normal again. I'm guessing it'll work until I reboot again. Googling around isn't turning up similar complaints about Lucid Lynx and the window manager. Before I go deleting preference files, anyone else know of this kind of issue and what could be done about it? Or should I start taking the stab in the dark approach of deleting preference files hoping one of them is corrupt or has something unsupported in it that's throwing LL for a loop?

  • Dell 36400 Display issue - "doubling up" intermittently

    - by alex
    I've got a Dell E6400 It's suddenly developed an intermittent fault with the display Every now and again, it seems to boot up with "double vision" By that I mean, its split horizontally, with each half showing the same thing, but with low resolution, and looks grainy - if that makes sense (I will try to get a couple of pictures if I can) I haven't changed any hardware or anything. I have re-built windows, to see if that fixed the problem, it didn't. I've upgraded the BIOS to see if that would help, still same problem. I'm out of ideas :-(

  • How can you connect to a SQL Server not on your domain?

    - by scotty2012
    I have a test machine that's not allowed on our domain because we are testing corporately unsupported applications (SQL 2008 and Server 2008). I want to use management studio to connect to the SQL2008 server but can't get it working. I have authentication set to mixed-mode, I've checked 'allow remote connections to this server', but when I try to access it, I get the error A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53) Since it says the provider is Named Pipes, I enabled Named Pipes on the server, but still no dice. I've tried connecting to the system name, the IP, the system name\instance and IP\instance, all to no avail. Is what I'm trying to do not possible? Edit: Well, through some basic troubleshooting, I've found that I can't ping the server from my client computer, but I can ping the client computer from the server? They are both plugged into the same switch, and are sitting next to each other. The windows firewall on the server is turned on, is there some specific settings I need to enable? DAH! So it was the firewall blocking me. How can I enable the firewall and still connect?

  • Rack layout tools

    I'm wondering if there's any tools (preferably offline) that would allow me to layout all of the new equipment that will be going into several standard racks. Currently I'm using Excel to map out all of the slots columns for the data but I suspect that there is some better method of doing this. Suggestions? Edit: Dell has an online tool, but doesn't seem very good at actually saving the data that you're working on (and obviously it's geared towards Dell hardware).
