• What is the current state of development for the FLAC codec?

  - by TwentyMiles

  I have a pretty large collection of FLAC files created from my CD collection. I love the FLAC format and the sound quality that you can get from it. Lately, however, I've been trying to write a few tools to manipulate the files and I've been noticing what seems to be a stagnation of the community around the codec. Some of the links on the official FLAC page point to thing that are no longer relevant (7digital, for example, appears to no longer sell FLAC encoded songs). It's pretty hard to find hardware players that support FLAC any more (most noticeably it's not present on lower end players when it used to be, and playback is absent on Android). Programming language tools (Java and .NET libraries) are at best old, and at worst unfinished. What's the current state of FLAC development? Has it been replaced by another codec?

• Disk full, du tells different. How to further investigate?

  - by initall

  I have a SCSI disk in a server (hardware Raid 1), 32G, ext3 filesytem. df tells me that the disk is 100% full. If I delete 1G this is correctly shown. However, if I run a du -h -x / then du tells me that only 12G are used (I use -x because of some Samba mounts). So my question is not about subtle differences between the du and df commands but about how I can find out what causes this huge difference? I rebooted the machine for a fsck that went w/out errors. Should I run badblocks? lsof shows me no open deleted files, lost+found is empty and there is no obvious warn/err/fail statement in the messages file. Feel free to ask for further details of the setup.

• Installing Windows 7 on a BSOD Windows Vista (ASAP)

  - by anonymous

  On a previous question i posted, i asked for help on fixing my windows vista box because it keeps going to blue screen. No one seems to have the answer, so now i want to install Windows 7. I want to know if i can install 7 without having to reformat my hard drive and having to lose all my files. I've already confirmed the hardware is working because i installed Ubuntu 9.10 on my external hard drive and it runs on my system fine. I tested the memory using vista's memory test and Ubuntu's memory test. here's the previous post: http://superuser.com/questions/125897/i-really-need-help-resolving-a-window-vista-bsod-blue-screen-crash-on-my-deskto

• xinet vs iptables for port forwarding performance

  - by jamie.mccrindle

  I have a requirement to run a Java based web server on port 80. The options are: Web proxy (apache, nginx etc.) xinet iptables setuid The baseline would be running the app using setuid but I'd prefer not to for security reasons. Apache is too slow and nginx doesn't support keep-alives so new connections are made for every proxied request. xinet is easy to set up but creates a new process for every request which I've seen cause problems in a high performance environment. The last option is port forwarding with iptables but I have no experience of how fast it is. Of course, the ideal solution would be to do this on a dedicated hardware firewall / load balancer but that's not an option at present.

• Virtual box lost files

  - by Paul Lloyd

  I have been running Virtual Box on a Macbook Pro for a year or more, with an old version of Windows XP running on the virtual machine. Recently my Mac battery dies completely and I had left VB / Windows running. When I re-started the Mac, VB would not load. I reinstalled a recent download of VB from a DMG file I had stored. Now VB starts but when I try to start the virtual machine I get the following message, Failed to open a session for the virtual machine Windows XP. Failed to load VMMR0.r0 (VERR_SUPLIB_WRITE_NON_SYS_GROUP). Result Code: NS_ERROR_FAILURE (0x80004005) Component: Console Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb} I have been backing up the MAC using Time Machine and have backups going back months. I really need to access the windows files as they have my Accounts and other business critical stuff. Any ideas please, or does anyone know where I can get some support for this combination of hardware / software, apologies I am a novice in this area. Thanks in advance.

• How to install old versions of gcc on Fedora without a VM?

  - by mikeh

  Hi, I need gcc 4.3 running alongside the shipped 4.4 on an FC13 machine. I can't do the VM solution discussed at http://serverfault.com/questions/88445/how-to-install-old-versions-of-gcc-on-fedora-12 since I need hardware access (CUDA computations on the graphics card). There's no compat-gcc-43 package (only compat-gcc-34). So I've built gcc by hand and am now trying to decide how to "install" it. Could anyone confirm that this was my only option, and/or suggest a best practice for how to manage the side-by-side gcc versions?

• Quiet Sound while recording using the "Stereo Mix" option on Windows XP.

  - by DragoonX

  I'm trying to record some of my work, and the video capture program I'm using works fine. It's HyperCam2, and since it's not really professional, I don't care about that little thing in the corner. Anyways, If I check the record sound option and put it on the highest quality, and I want it to record the sounds playing from my computer, I have it record the "Stereo Mix" setting. However, after a quick test, I saw that even though my computer was at max volume, the recorded sound was very quiet, almost inaudible. Thinking it was just HyperCam, I downloaded Audacity, and only met similar results. While I'm not entirely savvy with hardware, I BELIEVE this to be my soundcard: SoundMAX Integrated Digital HD Audio

• Upgrade AirPort on Macs to support Snow Leopard's Wake on Wireless/WLAN?

  - by wojo

  Snow Leopard now supports Wake on WLAN, but not all hardware supports this. For example, my Octo Mac Pro from early 2008 has an AirPort card, but it does not support this. Nor does my 2007 2.33GHz MacBook Pro. For reference to what is needed, look at http://www.macrumors.com/2009/08/28/a-closer-look-at-snow-leopards-wake-on-demand-feature/ which includes a screenshot of what the System Profiler should show. It's pretty hard to find Apple parts, but is it possible to put newer cards into these machines to have them support Wake on Wireless?

• Transferring Windows XP Mode VM to Another Machine?

  - by Omar Kooheji

  I've been running Windows XP mode on my Windows 7 Laptop for a while now and I've got my VM set up just how I like it. I am switchign laptops due to an intermittent hardware failure. Is it possible to transfer my Windows XP mode VM to my new laptop? I know it's just a Windows Virtual PC VM, how would I go about transferring it if this is possible? Will the Fact that I'm moving from Windows 7 Ultimate to Windows 7 Pro make a difference? AFAIK they both support Windows XP Mode.

• Recommended CPU upgrade for Dell Vostro 220 with E7300 processor?

  - by Justin Grant

  I've got a Dell Vostro 220 with an E7300 processor (Intel Core 2 Duo @ 2.66Mhz, LGA775 socket) and I'm thinking about upgrading my processor so I can run Windows Server 2008 R2 with Hyper-V, which requires Hardware Virtualization support in the processor. Yes, I know this is underpowered for a server, I'm actually using it as a desktop machine but I'd like to use Hyper-V instead of Virtual Server (which I'm using now for running VMs). I'd like to keep the same motherboard and ideally the same CPU fan and RAM too. Any suggestions for a good, relatively cheap (under $200) processor upgrade?

• Disable Bing search entirely from IE when using sysprep

  - by takesides

  I'm creating a Windows Server 2012 R2 image for our product (an all-in-one appliance installed on server hardware) and I am having incredible trouble with getting Bing removed from Internet Explorer. Our clients do not want Bing at all, not as a default search, not as a "search from address bar" feature, not in any sense. I've managed to configure everything else that I want in IE using WAIK to generate an unattend XML file but this has me completely stuck. Ideally I want Bing removed from IE altogether but I would make do with it just being completely disabled. I can find no options in either WAIK or Group Policy to configure this as I need it. Any ideas gratefully received.

• Door with keypad that can be controlled by website

  - by pbz

  Hi, I'm looking for some kind of the door/system that would allow us to install a door lock with a keypad. When somebody goes to that door they would enter a number that would open the door. The twist is that we need to be able to change the key combination that opens the door from a website. It needs to allow me to programmatically change the key combination required to open the door without somebody physically going there to do it. Any ideas what kind of hardware/software we would need to do this? Thanks a lot!

• Using 2-port LSI 2308-8e card to control 24 SAS HDDs

  - by GregC

  I would like to rely on a RAID-on-chip solution to control 24 SAS hard drives in a direct-attached environment. How would you approach this to get best bandwidth given that I'd like to spend less than $10,000 on the interconnect. I've read that LSI 2308 chip can easily handle 8-drive SSD RAID6 in hardware. I'd like to harness its power to control 24 SAS hard drives over an expander in an external enclosure. Currently I use an Infortrend S24S-G2240 external enclosure. It provides its own controller and expander. I'd like to use LSI 2308 controller for RAID6 somehow instead of the mystery controller in the enclosure. P.S. I tried to create SAS-expander as a tag, but my rep on this site is low.

• How to diagnose repeated freezing of windows 7 (comes back alive in few seconds)

  - by Akash Kava

  I installed Windows 7 in a 3 year old machine, it installed successfully, took all drivers and running great, but what happens is every 5-6 minutes it freezes for few seconds... 30 seconds to 1 minute and then comes back alive. I checked Event Viewer, nothing matching the frozen timeline. I would appriciate any help on how to detect causing service/hardware. After it comes alive, everything runs normal, I did run task manager and checked cpu usage, at time it freezes just before and after that no task took more cpu or memory, it was like idle machine. No external usb drives or no devices, on board intel desktop board with SATA HDD, SATA hdd running in absolute good mode.

• How can I login to Ubuntu using a USB serial port?

  - by marc

  How can enable remote terminal login into Ubuntu 9.10 using a USB serial port? I created device /dev/ttyUSB0 and i want to allow logins using Hyper-Terminal. I found some resources but they are related to real hardware rs232 ports. I can't find any information about USB converter. So far I have established connection between that USB-serial port and my laptop. I can send text to the port (cp sometext.txt /dev/ttyUSB0) and read it using hyperterminal. What do I need to do to enable logins on this port?

• dell u2410 3dMark Benchmark distortion problems

  - by Scanningcrew

  Ive been doing burn in testing for a new system I have put together and I am running into some video distortion problems with running the 3DMark benchmark tools (Both 06 and Vantage). The graphics will be fine, then sometimes during a test switch the screen will light up with thin horizontal ranibow lines (Something that looks very "glitchy") If i turn the monitor off and back on it clears up. All the tests "pass" and my system gets good marks but it concerns me if I might have problems with games (The screen returns to normal if I dont resest monitor and just let tests pass). I want to return a problem component now before its too late if it is something with the new hardware. Also, I am monitoring temp with thermal laser gun and the card itself is not going above 65c. Any ideas? System: Asrock x58 Xtreme - Last BIOS (1.80) EVGA Geforce GTX 285 w/ latest nvidia drivers (Connect via DVI1) Dell U2410(Set to 59hz refresh 1900x1202 -although I believe benchmarks run 1200x1024) Windows 7 Ultimate 64 12Gb DDR3 1600 RAM

• Unable to run VMs on hyper-v

  - by PRAWAT-DS

  Folks/Mates, I need some advise and assistance regarding the testing of Hyper-V. Here is my h/ware configuration: 1) Intel i5 processor (i5-750) 2) Intel M/B DP55WB 3) 6 GB DDR3 RAM OS = Server 2008 R2 Standart (evaluation copy). I installed 2008 r2 on my machine and added hyper-v role to it. I created 2 VMs and installed OS. But after finishing the OS installation the VMs are not booting up. After finishing the OS installation, the VM reboots automatically (normal behaviour) and shows "preparing your system for first time" after that it reboots and didn't come online. Few things to notice, when I am running "securable" on my server 2008 R2 OS it shows that processor is not supporting h/ware virtulization, but (since my desktop is dual boot) when I am running "securable" on my windows 7 OS, it shows that process "does" supports hardware virtulization. VT option is already enabled in BIOS. Any help and suggestions are highly appreciated :) Thanks in advance. Pradeep Rawat

• cloud/grid computing

  - by tom smith

  Hi guys. I'm appologizing in advance to the guys who will tell me this isn't a tech/server/IT issue! But I've been beating my head around this for a couple of days now. I'm trying figure out who to talk to, or which company I can approach to try to see if there are Grid/Cloud Computing companies who have programs setup to deal with colleges. I'm dealing with a compsci course, and we're looking at a few projects that would require a great deal of computing/computational resources. But in calling different companies (HP/Rackspace/etc..) I'm either not getting through to the right depts, or to the right people, or the companies just aren't setup for this. There are plenty of companies who have discounts for desktop software/hardware, but who in the biz deals with discounts/offerings for Cloud/Grid Computing solutions?? Any thoughts/pointers would be greatly appreciated. Thanks -tom

• What are the best options for a root filesystem hosted on SSD under Linux

  - by stsquad

  I'm working on an embedded system which is going to be booting and hosting it's rootfs on an SSD disk. We are currently looking at using Intel X-18M SSDs. The file system structure will have a fairly static /usr section (modulo software upgrades) and an active /var and /var/log for maintaining state and logging. Given the wear-levelling done by the underlying flash does having separate partitions help or hinder? As modern SSDs appear as straight block devices and hide their mapping magic behind their firmware is there any point trying to optimise the choice of file-system that sits on-top of the SSD? Finally does enable SMART monitoring make any sense in this context or are their SSD specific ways of determining the underlying health of the storage hardware?

• RAID P410i and P812 performance issues

  - by Alexey

  I'm having much trouble with I/O performance of HP DL360 server with two RAID controllers - P410i and P812, Windows Server 2008, 36 GiB RAM and 16 x Intel Xeon x5550. The server runs a bunch of tasks producing heavy sequential I/O, and after about 20-30 minutes of intensive work it looks like the tasks are stuck, not using CPU and with enough free memory (so this cannot be a bottleneck). The same tasks were running quite well on the older server (Windows Server 2003, 4 x Intel Xeon, 12 GiB RAM). RAID cache is present, write-cache battery is installed. Cache is configured as 25% readahead/75% writeback. The swap file resides on the logical disk served by P410i and other logical disks are on P812. Can someone tell me what can be the matter of this? Is this a hardware problem or misconfiguration?

• Linux Logitech QuickCam Pro 9000 - microphone issues

  - by drahnr

  I got a Logitech Quickcam Pro 9000, the cam itself is working as it honors the UVC spec. This fancy WebCam has a integrated mic which worked some time before but now, it does no more. (Note: I use pulseaudio as it is a USB Mic and I am not really keen on the hassle of ALSA setup) Things I check already are if it gets detected at all: $ lsusb |grep Logi Bus 002 Device 002: ID 046d:0809 Logitech, Inc. Webcam Pro 9000 is muted in alsa-mixer - not the case, volume at 100 pavucontrol shows it too, but no input level bar! On top of that, if I open the gnome3 (fallback mode) audio panel(from the desktop panel), and disabel/reenable it in the hardware tab, it works "for some time"... Any hints? Any ideas? I am really out options for now, and the fact it worked like 6 months ago (perfectly) makes it no better.

• Why doesn't my sound card start? It reports code 10.

  - by Sarim Ali

  When I installed the XP for first time my sound card was working fine. But only after the first reboot it has stopped working. Under Device Manager, the section "sound video and game controller" the entry YAMAHA Native DS1 WDM Driver, has a exclamation mark on it. On left clicking and selecting properties it shows this message "This device cannot start. (Code 10)". On trying to update driver it says a better driver can not be found. Any idea how I can solve the issue? Update: As suggested by harrymc I uninstalled the device "YAMAHA Native DS1 WDM Driver" , and scanned for hardware changes. The windows detected and installed the soundcard and it started working properly.BUT, after restarting the same problem occurs. So, now everytime I reboot the computer I am stuck to, repeating the process of uninstalling the device to make it work.

• Windows 7 Via Hyperion 4-1 drivers

  - by Gratzy

  I have a clean install of Win 7 on some relatively old hardware. Everything works pretty well however my cpu is pegged at 100% most of the time. Task Manager shows srvchost as being a main culprit of course but also system interrupts. I have a Biostar socket 478 MB with Via chipset. I have tried to find Windows 7 drivers for this but when I download and try to install what VIA/BIOSTAR say should be good for all OS's it will not load. I get a message saying can't find components for this OS. Anybody have any idea where I might find suitable drivers for the Chipset? BTW I'm not using the integrated graphics on the board but have a radeon 4500 pci-e card.

• Universal Windows XP With Ghost and Sysprep

  - by RobertPitt

  Hey I have an idea but im not sure whether it is possible and looking for advice on how to accomplish this. If i was to try and deploy Windows XP Sysprepped image from a Lenovo Thinkcentre 6073-CTO and tried to drop it onto a Dell Optiplex for instance I would get a BSOD due to the hardware change. What im looking to do is create a few images like so: Windows XP x86 SP3 (Sysprepped) Windows XP x64 SP3 (Sysprepped) ... So that we can use throughout the organization without having to create individual images per computer type. Is there anyway's to accomplish this such as some modification of files pre-ghost, removal a certain drivers pre-sysprep Any advice is appreciated.
