• Open source report framework

  - by Tiax

  I'm looking for a open source report framework for statistics. A more detailed explanation is: We have a number of tests running on different servers collecting data (for example, login time) every 5min. What we need is a framework that collects this data (or exposes web services for us to push the data into the framework) and presents it in form of graphs and so on. Does anyone know of a framework that's easy to use out of the box but has the power to grow? If you know what I mean. Thanks in advance!

• Has anyone had luck getting an external hard drive working with a PCMCIA USB card?

  - by Carl

  I would like to know if anyone has had any success in getting and external 2.5" IDE hard drive in an external case (w/USB cable) working when plugged into a PCMCIA USB card. My hard drive doesn't work when plugged into my HT-Link Cardbus/PCMCIA USB 2.0 2-port card (NEC / 32-bit). My MP3 player will work fine when plugged into it. I tried plugging in both of the USB cables that are one one end (Y cable), and it doesn't make a difference. I read the problem may be insufficient power.

• Using VLC to Unicast High Definition Webcam over local gigabit LAN with low/zero delay

  - by Robin Day

  We're setting up a webcam "window" between two offices in the same buildilng. The two PC's are connected to the same gigabit switch. We're using VLC to stream the webcam over HTTP using the following commands. vlc dshow:// :dshow-caching="0" :dshow-size="640x480" :sout=#transcode{vcodec=h264,vb=0,scale=0}:http{mux=ffmpeg{mux=flv},dst=:8080/} :no-sout-rtp-sap :no-sout-standard-sap :ttl=1 :sout-keep vlc http://192.168.0.1:8080 :http-caching="0" Even with the caching set to zero, the delay in the image is a good 2-3 seconds. The CPU usage of each pc is also maxed. I'm guessing it's the transcoding that's causing much of the delay. Can anyone give me some changes to these command lines that will reduce the transcoding power, or send the webcam over a different protocol, or anything that will reduce the delay of the cameras? Bandwidth is not an issue at all as the pc's can be connected to a dedicated switch/vlan if required.

• How do I pick a motherboard?

  - by EpsilonVector

  When building your own computer one part was always a mystery to me: the motherboard. Picking a CPU/GPU/memory is easy- you just figure out where the various chips are in the low end to high end scale, do a little market research on what current games demand, and pick the parts from their respective continuums of low-to-high-end models. A mother board is more complicated though. Its features are not as obvious as "this motherboard is faster than that motherboard". Now you need to deal with part compatibilities, bus speeds, maybe power management stuff, etc. I'm interested in a short guide for selecting a motherboard, especially- what pitfalls to avoid (for example, can bus speed become a bottleneck?). To clarify: I'm not looking for motherboard recommendations. I'm looking for guidance regarding how to evaluate the fitness of a motherboard given the rest of the computer parts.

• Ubuntu 9.10 freezes when HDMI port is connected

  - by Felipe Hummel

  Hi, I have a Sony Vaio FW350 with a HDMI output. I'm trying to use it under Ubuntu 9.10 with a LG LCD monitor 21,5'. I've tried two approaches: Boot the laptop with the HDMI cable connected and monitor turned on. Result: LCD Monitor keeps turned on but the whole screen is black and Ubuntu do not seem to be initializing. Boot Ubuntu until the end. I then connect the HDMI cable into the Laptop. The mouse and the whole system freezes. In both cases the only way to turn off the laptop is holding the power button. I've looked around the internet for similar problems, but only found workarounds for the same problem with VGA input, not HDMI. I also tried to use metacity before connecting the cable, but still got the same result. Any hints?

• Looking for a router with multiple WAN ports and load balancing

  - by Cyrcle

  I'm going to be moving in a few months. The location I'm moving to is great except it's on a road with very few people, so the internet access option is limited to DSL at 1.6Mbps down, 384kbps up. This is much slower than I'm used to. One option is to get at least two of the DSL lines. There's also good possibility that I'll be able to get WiMax or similar. I've been looking around a bit and it seems like what I need is a load balancing router with multiple WAN ports. Can anyone recommend some good ones? I could also go with a small power efficient Linux box with multiple NICs. What would be good software for that? It'd need to be able to handle around 10Mbps. Thanks for any help

• Keyboard doesn't work after Windows resume from sleep (S3) -- how to fix?

  - by Marco Z

  I have a weird issue with my keyboard after resuming from S3 sleep: I can type perfectly for maybe 5 seconds, but afterwards the keyboard ceases to work until I hibernate or restart (or sleep again -- see below.) The rest of my system runs just fine -- just the keyboard apparently "freezes" up. Some closer observations: The keyboard will work for 5 seconds (and freeze again) every time I resume from sleep, even if it was frozen from a previous sleep The caps lock light will work fine within the 5 seconds. But after the keyboard "freezes", the light will remain on, but I'll be unable to turn it off. Perhaps this means power wasn't cut off from the keyboard, but it's just some software freezing up the port??? Given this info, would this indicate a problem with Windows itself? Drivers, maybe? Can I rule out the BIOS as the culprit? Finally, any ideas on how to fix? Thanks! Specs: Windows 7 x64 HP tx1000 laptop

• How can I determine what is causing SQL Server 2008 Express to hang Windows 7?

  - by thelaughingdm

  I have SQL Server Express 2008 installed on a Windows 7 (32-bit) developer workstation. Whenever I run an application that accesses SQL Server the Windows 7 shell hangs when the application closes. Applications like Windows Explorer and Task Manager become completely unresponsive. The task bar will not allow any interaction. The only way to recover the system is to power cycle. Two of the applications in use when this happens are NUnit and SQL Server Management Studio. NUnit always runs the unit tests that interact with the database fine. SQL Server Management Studio will sometimes cause the problem while trying to explore the database. The Windows event log does not show any events that are obviously connected to the problem. I have reverted and reinstalled SQL Server Express 2008 several times. What can be done to identify what is causing SQL Server Express 2008 to hang the Windows 7 shell?

• Decent 1gb switch (16-24 port) for rack...

  - by TomTom

  Hallo, for a rack containing a smaller nubmer of servers (5 at the moment, going to stay in this area), I look to replace the currently aging 100mbit switch with a 1gb switch. This is for the backend between the servers. I expect some ISCIS traffic there ,so a 10gbit option would be nice (preferably for two ports, as extension modules). I dont need management, this is a pure backend of an internal cluster. I do VLAN, but there is no sensible management the switch can do there. I wuold like: * 1he only, obviously * preferable limited moving parts. * Low price ;) * Enough power to run at least half the ports in full speed at the same time. Anyone any recommendations?

• Ubuntu 11.04 hangs at "checking battery state" while booting

  - by MisterSir

  When I try to boot Ubuntu 11.04, it just hangs when it gets to checking battery state. I know this issue is usually related to graphic drivers, but it worked like a charm for months now. Last time I was on Ubuntu I updated my system with the update manager, so maybe an update caused it. Anyway, I really need Ubuntu. I'm in the middle of work on a website and I have a deadline, so I need some help over here. Thanks. p.s. I tried reinstalling gnome-power-manager. Didn't work. And I'm not on a laptop.

• Any experience with SATA SAS Interposer Cards?

  - by korkman

  Driven by the current price difference between SATA and SAS disks on one side and the potentially bad behaviour of SATA disks in bigger storage arrays on the other side, I have found so-called SATA-to-SAS interposer cards. Advertised as "seamlessly adding SAS capabilities to existing SATA disk drives", I wonder if anyone here has had some experience with these or similar products. The major benefits I can identify are the increased cable voltage (if all drives are SAS connected), the ability to power-cycle the drive and multipath (if desired). Obviously the SATA drive will still have to be RAID edition. The question is: Do these cards indeed increase the overall reliability of a storage system, or will failing SATA disks cause trouble nevertheless? Edit: I'm not asking for hypothetical answers, only actual experience please. I'm well aware that the typical 10k SAS drive is more reliable (and better performing) than 7200 SATA drives. But how does a nearline SAS, which is phyiscally the same disk as its SATA counterpart, compare to the SATA version with interposer?

• Blackberry Won't Sync: Says Processing

  - by Noah

  I have a blackberry storm 2 and I have it set up to sync, just like I've done with all the other ones in the company. They pull the address book/contacts from outlook, and aren't synced to an exchange server. I have everything setup and then when I hit synchronize it flashes "processing" the phone shows it trying to sync and then it is done in less than a second. It did warn me that the computer was not supplying enough power to charge the device and it said that I should make sure the drivers are correct. Also, I was warned that the device might not function properly down in the bottom right hand corner. Any ideas? I've uninstalled and reinstalled the blackberry software off the disc.

• Trying to turn an WD Mybook 1TB to slave drive in PC

  - by Steph W

  Yes I realise that most external Hard Drives would not be transitioned into internal sitting Hard Drives, but unfortunately we broke the miniUSB connection that transfers the data from external Hard Drive to laptop. What we are TRYING to do now, is get the WD MyBook 1TB to funtion alongside (preferably as SLAVE) to my currently exsisting Desktop Hard Drive. both are SATA drives. We have the SATA power, and Data cables, and these are in place (but - somehow NOT working) - Help please - I am not computer illeterate, just don't know how to switch this so it works. How do I turn one into master, and the newer one (that was external) into the slave drive?

• My MacBook Pro (2011) is dead

  - by Dave

  I connected my Sony digital camera with the MacBook and the screen turned black. I wonder why because the Sony camera was not on at the time and technically could not be accessed. So I thought it might be temporary and I turned on my camera. Well, it did not work, but my MacBook Pro has been dead since then. It will not turn on - when I hold the power button for five seconds, nothing happens. When I connect the charger cable, the green light is very dim and blinks a little (with about 20% illumination). I wonder what the problem is. I have to call Apple Care, but just so that I know, what could be wrong? Is my MacBook permanently dead? It might be under warranty but I am not sure.

• USB-keyboard & mouse powered off in windows-7

  - by sinned

  I have a problem with a pc where usb devices are not getting any power as soon as windows starts up (it works in preboot). This pc has no ps/2, so there is no chance for input, also not in secure boot mode. I "tidied up" using sysinternals autostart, so there is a chance I messed something up here, although I'm quite sure I only deleted some old printer drivers from autostart. I do not know how to reset this, I cant even log in because there is no input possible. I could use a linux live cd, but I don't know what to do there because there is no sysinternals from linux into a not running windows... To make things even worse, I have the windows installation completely encrypted with truecrypt, so I haven't even tried windows recovery cd yet. There is no loss of data since I can access the disc with a live-linux, I only want to use it again without resetting up everything. Any suggestions?

• Why the different coarse threaded screws?

  - by Luke

  I'm seeing more and more of these screws (pictured below), which are almost triangular. I find I can only put them into Power Supplies and PCI(e) cards in cases, but they will break/strip away if I put them into a hard drive or a standoff for a motherboard Notice the triangular shape on it? On the Root Access chat, I started asking, but no concrete answer yet. I don't assume it's a production flaw, as I've seen hundreds and replaced them with the "proper" round screws. It is coarse-threaded, not fine-threaded (i.e. for a DVD drive or floppy drive). What are they for, and why do we need them instead of the regular round ones?

• How to charge an iPhone on a Windows PC without Installing iTunes

  - by Martin Hollingsworth

  I want to be able to charge my iPhone on my work computer, which is running Windows Server 2008 SP1 64-Bit. When I plug the iPhone in with the USB cable, it will not charge. Windows attempts to locate a driver for the device but only comes up with a generic Camera device and even if I allow that to be installed, the iPhone still does not charge. I have checked the computer's BIOS settings and did not find anything relating to power on the USB devices. I also tried this on ports at the back of the computer in addition to those on the front. The PC is a Dell Optiplex 780. As far as I can tell USB devices do not charge unless Windows has installed an appropriate driver. Since it is a work computer I do not want to install iTunes which does include a driver. I have a workaround that I will post as an answer for reference.

• Sharepoint insists it knows the link to my UNC and won't let me remove hyperlink formatting

  - by ray023

  We have a file share at work (one I do not have the power to rename) and it contains a space in it: \\WorkFileShare\Visual Studio\SP1 I'm creating a Wiki Entry that informs users they can locate the VS2010 SP1 download on this Share. For some reason, SharePoint will highlight and hyperlink the UNC up to the space. (I've been dealing with this behavior for years in Outlook and I fix by putting focus on the character before the space and then hitting backspace to remove the formatting). Simple enough and SharePoint also removes the formatting when you backspace on the character before the space. However, as soon as I move away from the link, SharePoint goes right back to highlighting and hyperlinking what it thinks is the UNC. Naughty Sharepoint!! So does anyone have any idea how to clear the formatting? NOTE: Highlighting the text and clicking on the "Clear Format" icon does not work.

• Debian crashed, file system is read-only and cannot backup - How Do I find/mount a USB drive?

  - by Spiros

  We have a Debian server (vm's) here at work and the server crashed after a power failure. I can only boot the system in maintenance mode, and the whole file system is set to read only. I can run fsck though maintenance mode, however I would like to get a backup of some files before I do. Problem: I cannot access the net since there is no network connectivity in maintenance mode, and for some reason I try to add a USB flash drive to the computer but I can't find it through the console. Question: how to you find/mount a usb drive on Debian? I have tried several resources from the internet but nothing worked. Is there any other way I could get a backup of my files? I cannot start networking since the filesystem is set to read only. Any help would be appreciated.

• How do you explain ethernet cable problems to non networking people?

  - by Bryan McLemore

  We've recently been doing a large network migration in our datacenter. We've had a few cables in this start to deliver really bad pings (in excess of 500ms on a LAN) before they could be replaced. The cables we were replacing weren't made the best. They where all hand made and the runs were so short on some of them that the bend radius was definitely too tight. Some of them ran in bundles right in front of the heat exhaust of the power supplies. The cables were running ok until we started pulling the ones surrounding them out. Then a few started having the problem I mentioned above degrading performance and causing reliability issues. I'm trying to figure out the best way to explain this to non networking people. Is there any documentation that people could recommend or other methods?

• How to choose between Mac Laptop and Desktop

  - by Sakamoto Kazuma

  I am looking at getting a Mac soon for both iPhone development, and video editing. Should I be looking at a desktop or MacBook? I do not plan for the machine to move from my desk at home, so portability is not an issue, however it will be next to both a windows 7 desktop as well as a Linux laptop with dock. Main things that I'm concerned about is whether or not a MacBook has the power needed to do the video editing that I'm planning on doing and whether or not I can afford a desktop.

• PC powers up but there is no display

  - by Matthew

  I built a computer with standard components I bought from Newegg about three years ago. It ran great for 2 years and has sat powered down for the last year. I tried to power it up today and the display was blank. It powers up, lights come on, drives start spinning but there is nothing on the display. I verified that the monitor and video adapter work. I also tried the video adapter in a different slot on the mother board with no luck. What's the next thing I should try? Is the mother board shot? Thanks.

• Streaming audio to headless linux box

  - by Ralph

  I have a dual boot (Win 7 + Ubuntu) PC connected via wifi with my music collection on a local HDD. I usually use Rhythmbox on Ubuntu or Winamp on Windows to listen to my music but I'll change if I have to. I also have a Raspberry Pi (low power PC running Debian) in the living room that is usually headless and connected via ethernet. The Raspberry Pi is also connected to my living room speakers via an amp. I would like to be able to stream music from my PC over the network to the linux raspberry pi. What software can I use to do this? Some sort of audio client\server?

• How can I access my mini-pc (RaspberryPi / MK802 / Mele A1000 / VIA APC) via ethernet/wifi without having Monitor?

  - by sky770

  Soon I will be getting my own mini-PC (RaspberryPi / MK802 / Mele A1000 / VIA APC). But I was wondering whether is there any possibility that I can just power up and access my mini-pc's OS by connecting it to wifi/ethernet link and remotely access it over the LAN without actually needing a monitor (throughout the process?) ? I currently own a laptop and need a download box and later will be getting a HDTV for converting to a HTPC :D So, I don't really own a spare monitor now but I do have an extra keyboard and mouse. Is there exists any linux distro for the same? which I can use to directly fireup my mini-pc and hook it up across my LAN to remotely access through my laptop? Any suggestions appreciated :) Regards, sky770

• oracle virtualbox doesn't work for host Kubuntu since Lucid Lynx 10.04

  - by 13east

  I have a thinkpad edge 14 core i3 2.4 ghz and 4g ram; I have tried kubuntu 10.04, 10.10, 11.10, 12.04 and 12.10 (all x64 architecture); Both oracle and ose virtualbox only works properly to install XP and windows 7 quest system on kubuntu 10.04; For every other kubuntu release since, the guest installation goes as far as formatting the virtual drive, freezes at this step, and doesn't even go as far as copying files to hard-drive to begin installation. But virtualbox has not stopped responding to commands; I can kill that one specific window with the problem installation ("machine" - "close" - "power off the machine") and start over again without having to force-kill virtualbox application. If anyone knows how I can go about addressing this problem, any help you can provide would be very much appreciated. Thank You.
