• Controlling an amplifier power supply from Squeezebox/SqueezeCenter

  - by teabot

  I have a Squeezebox that is connected to an amplifier. I'd like the amplifier to switch on/off whenever the Squeezebox is powered on/off. I don't mind writing some plugin code to SqueezeCenter to do this but in hardware terms I am looking for off-the-shelf components. I imagine that I need some kind of Ethernet controlled power outlet. I have looked at X10 (I can't bring myself to link to their terrible site), but their product range seems extremely confused and it looks as though I'd have to use both RF and comms-over-mains to implement a computer controlled socket. Does anyone have any alternative suggestions? Note: Any components should be available and certified for use in the UK.

• Is there a simple Load Balancer app for development environment on Windows?

  - by djangofan

  Does there exist a simple Load Balancer app for development on Windows? I am running a pair of JBoss 5.x instances in a cluster on a single machine. Normally , this configuration is load balanced by a nice hardware load balancer but I am wondering if there is a simple piece of software to enable load balancing in my Eclipse dev environment. Basically, for example, I want a load balancer running on port 11111 that round-robins between the 2 clustered JBoss instances on ssl ports 8443 and 8543 . (or http port if thats not possible) I know that Glassfish has a built-in load balancer but I can't use Glassfish. One idea I have is to try to setup a separate instance of Tomcat with the "balancer" web app. Im trying that now... not sure if it will work... and its a complicated setup and I wish there was something really easy.

• TP-LINK-8901 modem does not connect automatically; only works in bridged mode [closed]

  - by Arash

  Possible Duplicate: Cannot Connect To Internet In Automatic (pppoe) Mode Of Modem My TP-LINK-8901 modem does not connect to internet with "always on" (automatic) connection. I have to put it in bridge mode and make a connection in Windows to connect to internet. Also, there is no configuration problem. What I did: Reset modem Update firmware Is there any way to solve the problem myself, e.g. through hardware or software? I can't have it repaired because the warranty already expired.

• Guaranteeing ACID properties for InnoDB databases.

  - by plinehan

  What steps must one take to ensure that an otherwise defaultly-configured InnoDB server is truly ACID compliant? The InnoDB configuration page mentions that the hardware itself must be configured to honor fsync calls, i.e. disable any write-back caches. This page mentions some other concerns, but may be conflating the binary log and the InnoDB log, and may be a bit out of date regarding default settings for MySQL 5.x. Upon reading the binary log document page it would seem that the "sync_binlog=1" setting is not required for ACID properties in general, only for ACID properties vis a vis point-in-time recovery and replication. So, is disabling write-back disk caching sufficient, or are there other settings that must be tweaked?

• Windows Vista stuck on crcdisk.sys

  - by hristo

  Hello everyone, I'm here with some Vista-trouble. After a cigarette-break I returned to my desk to find my PC with a black screen, and after failing to wake it up did a forced restart. I haven't been installing any hardware or software for quite a while. Ever since, Vista gets stuck on the animated 'Microsoft Corporation' progress bar with the animation still running and no hard disk activity. With an F8 and safe-mode + prompt I saw that the boot gets stuck at crcdisk.sys. I'm running Vista64 SP1. What could the problem be? Any advice?

• Corporate Wiki Organization - Technical Documentation

  - by Dave Jarvis

  Corporations have documents describing various aspects of their technical systems, including: Custom Applications Custom Development Frameworks Third Party Applications Accounting Bug Tracking Network Management How To Guides User Manuals Software Tools Web Browsers Development IDEs Graphics GIMP xv Text Editing File Transfer ncFTP WinSCP Hardware Servers Web Database Exchange File Network Devices Printers If you had to use a Wiki to manage the documentation, what other items would you add to the list, and how would you organize it? (For example, would Software Tools make more sense under Third Party Applications?) A few constraints: The structure should not go beyond three levels deep. Avoid the word "and" in favour of two different categories. Keep the structure general: it should appy as broadly as possible. Target audience is primarily technical, but could be visible by anyone.

• What software can I use to pinpoint why Windows Server 2003 takes 15 seconds for any operation?

  - by Dr. Zim

  Ram is about 1/2 in use, four CPUs are all but idle. I tried "Microsoft Server Performance Advisor" with no luck. No entries in the Event Log for hardware failures, etc. And yet I can click on the start menu and wait 15 seconds for any new attempt. Launching software takes 30 seconds to respond. The server has an 8 drive WD RE 250 gig each Dell Perc 6 Sata raid array with Intel gigabit network cards. Anyone have any software titles that could analyze what is going wrong with this server?

• Windows Disk I/O Analysis

  - by Jonathon

  It appears that we are having a problem with the disk i/o speed on our Windows 2003 Enterprise Edition server (64-bit). As we were initializing a database that created two 1G tablespaces on 3 different machines, it became obvious that the two smaller machines (each 32-bit Windows 2003 Standard Edition with less RAM) killed the larger machine when creating the files. The larger machine took 10x as long to create the tablespaces than did the other machines. Now, I am left wondering how that could be. What programs or scripts would you guys recommend for tracking down the I/O problem? I think the issue may be with the controller card (all boxes are hardware RAID 10, but have different controller cards), but I would like to check the actual disk I/O speed as well, so I have some hard numbers to work with. Any help would be appreciated.

• How to secure Firefox traffic (+DNS) through SOCKS proxy under Ubuntu 10.04?

  - by Maarx

  I'm using Ubuntu 10.04, and starting a SOCKS proxy with 'ssh -D', and setting Ubuntu to use it with "System - Preferences - Network Proxy". Firefox uses the proxy, and the proxy's IP appears when I visit a site like http://www.whatismyip.com/. My question is, is Firefox resolving DNS requests through this proxy? Is my web-browsing truly secure? (That is, until I exit the other end of the proxy. I know it's insecure after that.) (And I've verified the keys, I'm not being man-in-the-middled) (And--screw it. You know what I mean. Is it resolving DNS requests through the proxy?) I don't know how I would go about verifying such a thing for myself. Using additional hardware such as another debugging proxy is not an option. If Firefox isn't resolving my DNS requests through the SOCKS proxy, how do I go about fixing it?

• Toshiba monitor not displaying anything

  - by MirroredFate

  Alright, so I agreed to fix a friends computer, thinking it was a software problem, not hardware. I was going to use an XP disc and valid code to swap her from Vista to XP, as apparently Vista had some driver issues. I found out, however, that the real problem was her heat sink was completely clogged, causing the computer to overheat and shut down. So, I took the computer apart and cleaned the heat sink. However, after putting it all back together, and turning it on, nothing at all shows up. I plugged in an external monitor, and nothing shows up on that either. I have double, triple, decuply checked all the connections and everything appears to be plugged in, attached, and in the right place. I am out of ideas. So, my question is, does anyone have any clue what is going on, and have suggestions I could try?

• development and music recording machine suggestions?

  - by dean nolan

  I wasn't sure if this belongs on SuperUser so flag if so. I am looking to build, primarily, a windows development machine that is also good for recording using Cubase. I know I should use seperate machines but I'm on a budget this time of year. I also havn't kept up with hardware for quite a few years. Basically I know I want quad core, multiple monitor support (no gaming requirements). A lot of RAM, very quiet case and super fast HDD (SSD OR 10,000RPM)for compiling and latency. I will store libraries and other data on a USB drive. Sound card is not needed as I will be using an audio interface, all other music recording equipment is taken care of also. I could do with some decent monitor recomendations also. All suggestions welcome, thanks.

• "custom" routers for VPN - useful or waste of money?

  - by Andrew Heath

  I use VPN in China and my current service contract expires soon so I was checking what sort of plans are out there now. I found that Witopia offers a "Cloak Box", what appears to be a Linksys wireless router with allegedly hacked/custom firmware to support VPN. Aside from allowing multiple computers to share one VPN connection, is there anything else at work here to justify that price when most new routers are $100 or less these days? Or is this something targeted towards the cd-rom cupholder crowd? And yes, I've contacted them, but haven't heard back yet... EDIT I've heard back from the company - here are the details if anyone else is interested: the router is a Linksys WRT54GL running TomatoVPN custom firmware the hardware waranty is one (1) year, from Linksys/Cisco the VPN is hard-set, so any device connected to the router MUST use the VPN (Witopia blocks torrents) I've decided it's not for me, but hopefully this information will prove useful to others.

• Exchange 2010 domainprep messing up mailbox permissions on existing Exchange 2003 server

  - by tearman

  So our environment is basically we have an Exchange 2003 server, and we're attempting to move to Exchange 2010 gradually, and move to new hardware while we're at it. So our first step was obviously to get Exchange 2010 installed on the new box. However, after running the domainprep steps listed in http://technet.microsoft.com/en-us/library/bb125224.aspx (including PrepareLegacyExchangePermissions) our mailbox permissions get messed up. Normally, we have an AD security group for Exchange Administrators that allows anyone in that group to view all folders inside any user's mailbox. However, now, this functionality is gone and our Exchange Admins can't access anyone's mailboxes. We'd like to get this functionality back if we could. Thanks

• Re-enabling audio on an iMac

  - by Warren Seine

  Hello guys, I know Super User is not a 'tech support' forum, so I will try to make it short: my computer's sound does not work anymore. I have asked for support on the Apple board but I feel a bit on my own. To summarize, the Sound Panel of my iMac does not display any outgoing channel (headphones or internal speakers). It does not work on Windows either. Contrary to what it may seem, I have the feeling that it is not a hardware issue (and that GarageBand is somehow interfering). If you have an idea to solve the problem, please share. Making it work again is a lost cause without sending it back to Apple, so the question I'm asking is: What is the best workaround (cheap Firewire sound card?) for getting my sound back? Thanks.

• Kernel config file generator

  - by lisak

  Hey guys, could please anybody recommend some kind of kconfig generator that would trim modules and built-in stuff that is not needed according to current hardware ? The best I have found is this : http://lkml.org/lkml/2008/9/16/290 I don't care about compilation time and the amount of modules that are not built-in. I'm concerned about performance. I don't know how much memory and runtime is wasted on huge kernels with almost everything possible. I'm a java developer and I don't know what most of the modules and drivers are for. So there is not much I can disable and be sure that I don't screw it up. Thanks in advance

• Can I upgrade an Asus M51Sn laptop to 2x4GB of RAM? (DDR2)

  - by matteo

  My Asus M51Sn has 2 RAM slots which currently have 1x1GB + 1x2GB DDR2-800 SODimm RAM modules installed. I've found out that 4GB DDR2 SODimm modules do exist, though they are impossible to find in local stores nere here, but I've found them in online stores like these: http://www.pccomponentes.com/g_skill_ddr2_800_pc2_6400_4gb_so_dimm.html They seem to meet the specification, so can I replace both my current modules with 2x4GB modules, and reach a total of 8GB? Or should I worry about some limit (e.g. 4GB max or 2GB per slot) imposed by the matherboard, chipset or whatever? (I currently use Ubuntu 12.04 32 bit, so I plan to use the pae kernel, which supposedly supports 4GB ram on a 32bit system; or I may consider switching tu 64bit ubuntu; the question is about hardware limitations, not OS limitations).

• How to customize Windows 7 HAL library during installation (BSOD STOP: 0x000000A5)?

  - by koldovsky

  While trying to install Windows 7 x86 Ultimate on Samsung M40 laptop (Pentium M 1.7 Dothan, 2 GB RAM/ 100 GB HDD) i receive BSOD STOP: 0x000000A5: The bios in this system is not fully ACPI compliant. Please contact your system vendor for an updated bios. The bios on the system is updated to latest version. If ACPI is the real source of the issue it means that I possibly could use another HAL library. In Windows XP it is possible to install system with generic HAL library pressing F7 when installer asks to supply drivers, but on Windows 7 I can't find such option. Ironically, Vista installs and works nice, even if they said that Windows 7 is less demanding for hardware. Windows 7 Advisor also tells nothing suspicious. Can anybody tell me how to customize Windows 7 installer to use generic HAL library (if it is possible, of course) or point me to another solution?

• How can I watch TV on my Computer (Not Online)?

  - by Sammy

  Novice question here, but how can I watch TV on my PC without using online sites? I have heard of tv tuners but is it just a matter of hooking a tv tuner to your computer and that's it? Do I have to just buy a tuner or pay for a service as well? If no service needs to be paid for, will I get just regular channels or cable/satellite channels as well? Will my PC need to be connected to the Internet when I want to watch TV? Do I need any type of software aside from the hardware tuner?

• ATI / AMD HIS HD 7870 Graphics card fan speed below 16% / 20% 26%

  - by Thorsten Niehues

  I bought a AMD / ATI HIS HD 7870 to replace my old HD 4870. I noticed that the fan speed does not scale with the temperature: The fan speed does not get below 28% (read from catalyst / automatic fan speed) If I manually change it in the catalyst to 20% then it has the same speed than 28% : about 900-1000 rpm. With HIS iTurbo i manually can change the fan speed below 20%. But I noticed that changing the fan speed below 16% results in 3200 rpm. This is really stupid and annoying since my PC is a ultra silent PC and all fans are running with about 500 rpm when the PC is idle (windows / musik movies, etc.) Is there any way to change the fan speed to a reasonable speed like 500 rpm by software or hardware adapters (I really don't like to put a poti between the 12V line)

• Double VPN Network Authentication

  - by Pyromanci

  I have a project I'm working on and looking for some info. Right now I have a VPN network using Cisco Pix 501's for the vpn clients and a Cisco VPN Concentrator 3000 for the VPN Server. Since the Pix is constantly connected to the vpn, I want to add a extra level of authentication. Meaning when the user on the other end goes to access anything on the VPN they are asked for a username password before the connection is established. I've never done this sort of structure before. So I'm not even sure where to really being or even if my current hardware can do something like this, or if i need to through in some sort of radius/LDAP/Active Directory type server into the mix.

• What is causing my newly built PC with Windows 7 to BSOD?

  - by Ben S

  I recently built my own PC from parts and installed Windows 7 and I have been getting BSODs with various different stop codes. The latest was 0x24, but I've also had 0xd1 and 0x1e. However, Windows does not let me know where the fault occurred, so I have no idea how to go about resolving this. I know the cause is likely a hardware driver, but I don't know which and cannot find information about how to use the minidumps to troubleshoot my problem. I've uploaded the last three minidumps in case someone can make sense out of them and let me know what could be causing my BSODs. Thanks, Ben

• PS/2 vs USB keyboards: performance and energy consumption

  - by Mister Smith

  As far as I know, PS/2 keyboards are interrupt driven, while USB are polled. Typically a PS/2 keyboard was assigned IRQ_1 on Windows. I'm no hardware expert, but at a first glance seems like the PS/2 keyboards are more efficient. So here are my questions: On modern day computers, are PS/2 keyboard better (or faster), and if so, would it be noticeable at all? (e.g.: in gaming) Since they don't need polling, do PS/2 keyboards save energy compared to USB? (notice I'm not talking only about the peripheral here, but about the overall computer energy consumption). In case PS/2 had any advantage over USB, would adding a PS/2 adapter to my USB keyboard make the device as good as an actual PS/2 keyboard? Conversely, would adding a USB adapter to a PS/2 make it as bad as a USB KB? Thanks in advance.
