• Trying to retrieve data with a thermaltake blacX enclosure: Windows 7 believes the drive to be "uninitialized"

  - by Peeter Joot

  I have a laptop that won't boot. It appears to be a power problem ... laptop auto-turns-off within about 10 seconds of pressing the power button (with power buttons lighted temporarily and no display with or without external monitor). I've followed the dell troubleshooting guide which suggested reseating the memory modules and the hard drives, but that didn't help. Before trying to have the laptop serviced, I wanted to get some data off off the hard drive. I bought a thermaltake blacX enclosure, intending to use this to both use to retrieve the drive data with, and then later use as external storage. Following the instructions (insert cables, insert drive power on) goes fine, and Windows 7 on another laptop installs the device driver software. However, no drive letter shows up in 'Computer'. Under Computer-manage-storage I see the drive is there, and there's an option to "initialize" the drive. The Windows "initialize" dialog gives me the option to pick between "MBR" and "GPT" partitioning, which sounds like a good way to destroy the data on the drive. I'm thinking that I've purchased the wrong device for the job (or that my old drive is damaged). The old drive to recover info from is a Western Digital 500G/7200rpm SATA drive if that is relavent. Both the original laptop and the one I'm using for recovery are running Windows 7. Does anybody have experience with using a blacX enclosure to recover data off an already formatted drive?

• Games consoles won't connect through the TP-Link TL-WA500G Access Point

  - by Manfred Wolff

  I hope that someone can help me. I have several Laptops and other devices, all using my Wireless Router (Sky Digital Netgear) To extend the range to the back of the house, I purchased a TP-Link TL-WA500G Range extender. configured just as a pure repeater, it picks up the signal from the Netgear Router. The Netgear Router does the DHCP, handing out the IP addresses. This all works a treat with several different laptops and my iPone4S, but when my son tries to use his XBox360, Sony Playstation3 or the Nintendo Wii those devices fail to acquire an IP address. They just sit their waiting for the IP config. This also happens with my wife's HTC desire ONE Android phone. My son says that, when his HTC Desire C won't get an IP address, he just unplugs the AP briefly - the phone will connect and he puts the AP back on. Once he is connected to the Router, the AP won't disturb function. The Games Consoles don't seem to work like that. They stop working, when the AP is reconnected. I had my son try to configure permanent IP addresses, and he said that did not work either, though I have to confirm that, as I did not see that for myself. Has anybody seen this before? I have searched the Net and have not found any similar problems anywhere. I wonder if there is setting somewhere that would fix this. Many thanks for anyone reading this and trying to help. M

• Matched or unmatched drives for RAID arrays?

  - by Will

  Looking around there is conflciting information on this, with some strongly suggesting one or the other. From my understanding the issue with matched drives is that the wear on both drives is more or less the same, so the potential for the second drive failing with or very soon after the first is pretty high. People also claim matched drives give substianatally higher performance however assuming the unmatched drives are more or less the same (eg 2, 1 TB STATA II 7200rpm drives with 32MB cache), would the minor differences between say a Seagate and a Western Digital one (say one has a 128MB/s read rate, and the other a 150MB/s read rate, as well as I guess various other minor differences) actually cause any notable performance loss, ie potentialy worse than two matched 128MB/s drives, or does RAID not really care and give you essentially an optimal solution (eg upto 278MB/s total read speed for RAID 0 and 1) and similar for other RAID with more "unmatched" drives (5 and 1+0 come to mind as possibilities)? Also I couldnt find much info on how this is different on different RAID setups, eg RAID 0 or RAID 1, software or hardware RAID, etc. I'm assuming such things have an effect, and thats it's not all the same for RAID in general?

• Hard drive causing BSOD

  - by JoshIrving

  I've come across a problem after building my new PC and installing a clean Windows 7. I originally planed on a RAID 1 or 0 but after further research I decided against it. So I was left with two 1TB Western Digital Black SATA 6Gb/s hard drives. My plan now was to use my second hard drive as a backup (using Windows Backup or 3rd party software). I set both hard drives to AHCI in the BIOS and installed Windows 7. I went through the lengthy process of downloading and installing each driver manually (latest versions), using the motherboard disk for a list of what I need. After a few restarts and before installing any software, I took an image backup onto DVD and the second hard drive. First witnessed the problem during the first scheduled Windows backup. The progress bar froze at about 70% (doc backup done, image backup in progress). It stayed still for 2 hours until it blue screened. Next time the backup froze, I tried shutting down. It logged me out and got stuck at the last step ("Shutting down" and blue spinner) for an hour, until I hard shutdown. I later realised this hasn't got anything to do with the backup. I ended up blue screening on almost every shut down (same place). Turns out, it's because of the second hard drive spinning down or turning off. The computer will now shutdown properly, as long as I remember to read or write to the second drive before executing shutdown. I've now set "Turn off hard disk after: Never" - No problems, so far. Do I have dodgy hard drive(s) or should I investigate the POWER_STATE_DRIVER_FAILURE BSOD - can it be a driver issue? AHCI?

• Apache Named Virtual Hosts and HTTPS

  - by Freddie Witherden

  I have an SSL certificate which is valid for multiple (sub-) domains. In Apache I have configured this as follows: In /etc/apache2/apache2.conf NameVirtualHost <my ip>:443 Then for one named virtual host I have <VirtualHost <my ip>:443> ServerName ... SSLEngine on SSLCertificateFile ... SSLCertificateKeyFile ... SSLCertificateChainFile ... SSLCACertificateFile ... </VirtualHost> Finally, for every other site I want to be accessible over HTTPS I just have a <VirtualHost <my ip>:443> ServerName ... </VirtualHost> The good news is that it works. However, when I start Apache I get warning messages [warn] Init: SSL server IP/port conflict: Domain A:443 (...) vs. Domain B:443 (...) [warn] Init: SSL server IP/port conflict: Domain C:443 (...) vs. Domain B:443 (...) [warn] Init: You should not use name-based virtual hosts in conjunction with SSL!! So, my question is: how should I be configuring this? Clearly from the warning messages I am doing something wrong (although it does work!), however, the above configuration was the only one I could get to work. It is somewhat annoying as the configuration files have an explicit dependence on my IP address.

• Virtualhost one https site, the rest http

  - by RJP1

  I have a linode server with Apache2 running a handful of sites with virtualhosting. All sites work fine on port 80, but one site has a ssl certificate and also runs okay. My problem is as follows: The non-https sites, if visiting https://domain.com - show the contents of the only secure site... Is there a way of disabling the *:443 match for these non-secure sites? Thanks! EDIT (more information): Here's a typical config in sites-available for a normal insecure http site: <VirtualHost *:80> ServerName www.insecure.com ServerAlias insecure.com ... </VirtualHost> The secure https site is as follows: <VirtualHost *:80> ServerName www.secure.com Redirect permanent / https://secure.com/ </VirtualHost> <VirtualHost *:80> ServerName secure.com RedirectMatch permanent ^/(.*) https://secure.com/$1 </VirtualHost> <VirtualHost *:443> SSLEngine on SSLProtocol all SSLCertificateChainFile ... SSLCertificateFile ... SSLCertificateKeyFile ... SSLCACertificateFile ... ServerName secure.com ServerAlias secure.com ... </VirtualHost> So, visiting: http:/insecure.com - works http:/www.insecure.com - works http:/secure.com - redirects to https:/secure.com - works http:/www.secure.com - redirects to https:/secure.com - works https:/insecure.com - shows https:/secure.com - WRONG!

• Multiple SSL certificates on Apache using multiple public IPs - not working

  - by St. Even

  I need configure multiple SSL certificates on a single Apache server. I already know that I need multiple external IP addresses as I cannot use SNI (only running Apache 2.2.3 on this server). I assumed that I had everything configured correctly, unfortunately things are not working as they should (or maybe I should say, as I expected them to work)... In my httpd.conf I have: NameVirtualHost *:80 NameVirtualHost *:443 Lets say my public IP is 12.0.0.1 and my private IP is 192.168.0.1. When I use the public IP in my vhost my default website is being shown instead the one defined in my vhost, e.g.: <VirtualHost 12.0.0.1:443> ServerAdmin [email protected] ServerName blablabla.site.com DocumentRoot /data/sites/blablabla.site.com ErrorLog /data/sites/blablabla.site.com-error.log #CustomLog /data/sites/blablabla.site.com-access.log common SSLEngine On SSLCertificateFile /etc/httpd/conf/ssl/blablabla.site.com.crt SSLCertificateKeyFile /etc/httpd/conf/ssl/blablabla.site.com.key SSLCertificateChainFile /etc/httpd/conf/ssl/blablabla.site.com.ca-bundle <Location /> SSLRequireSSL On SSLVerifyDepth 1 SSLOptions +StdEnvVars +StrictRequire </Location> </VirtualHost> When I use the private IP in my vhost everything works as it should (the website defined in my vhost is being shown), e.g.: <VirtualHost 192.168.0.1:443> ...same as above... </VirtualHost> My server is listening on all interfaces: [root@grbictwebp02 httpd]# netstat -tulpn | grep :443 tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 5585/httpd What am I doing wrong? If I cannot get this to work I cannot continue to add the second SSL certificate on the other public IP... If more information is required just let me know!

• How do you permanently disable the 'This Connection is Untrusted' page on Firefox

  - by TheIronChef9

  I'm going insane. Can someone please help me to COMPLETELY DISABLE the 'This Connection is Untrusted' page on Firefox. Facts: I am running Firefox 23.0 on an Ubuntu machine (downloaded and installed ubuntu today) It is a work computer and I have to use my employer's proxy While visiting Webpages/webapps like Gmail or Google brings up the 'This Connection is Untrusted' page and I have to go through the whole tedious task of selecting 'I understand the Risks' and add Exceptions, etc. etc. The fact is, I don't care about the risks. I would rather this computer melt into the ground than have to see that page ever again. I want to dance naked in untrusted pages and not give a damn about the consequences. I just never want to see that page again. Ever. For some sites (eg. wikipedia), the css doesn't load and I end up seeing them in plain text. As a result these sites are completely useless. Wasted hours trying to solve this for stackoverflow.com. These issues happen on the Firefox on my Windows XP machine as well (also using the same proxy). I don't want to export/import certificates or create exceptions for every site that shows this bloody page. I just want this page gone. I don't want Firefox to tell me what's safe and what's not. Also, my system time and date are correct. I've also tried the lies on this page too with no good results. Edit: I've also tried the whole going into the Advance-Certificates-validation setup page and unchecked 'Use the Online Certificate Status Protocol (OCSP) to confirm the current validity of certificates' checkbox. Nothing happened even after restarting firefox or rebooting. I need help. Thanks.

• Apache https is slow

  - by raucous12

  Hey, I've set apache up to use SSL with a self signed certificate. With https (KeepAlive on), I can get over 3000 requests per second. However, with https (KeepAlive off), I can only get 13 requests per second. I know there is supposed to be a bit of an overhead, but this seems abnormal. Can anyone suggest how I might go about debugging this. Here is the ab log for https: Server Software: Apache/2.2.3 Server Hostname: 127.0.0.1 Server Port: 443 SSL/TLS Protocol: TLSv1/SSLv3,DHE-RSA-AES256-SHA,4096,256 Document Path: /hello.html Document Length: 29 bytes Concurrency Level: 5 Time taken for tests: 30.49425 seconds Complete requests: 411 Failed requests: 0 Write errors: 0 Total transferred: 119601 bytes HTML transferred: 11919 bytes Requests per second: 13.68 [#/sec] (mean) Time per request: 365.565 [ms] (mean) Time per request: 73.113 [ms] (mean, across all concurrent requests) Transfer rate: 3.86 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 190 347 74.3 333 716 Processing: 0 14 24.0 1 166 Waiting: 0 11 21.6 0 165 Total: 191 361 80.8 345 716 Percentage of the requests served within a certain time (ms) 50% 345 66% 377 75% 408 80% 421 90% 468 95% 521 98% 578 99% 596 100% 716 (longest request)

• Glassfish and SSL [closed]

  - by Richard

  I'm struggling to get SSL working on Glassfish 3.1.1. I've been following tutorials like http://javadude.wordpress.com/2010/04/06/getting-started-with-glassfish-v3-and-ssl/ and SO posts like this Issues with setting up SSL on Glassfish v3 The above links are for information only. I've summarised what I've done below. As far as I can tell I'm doing everything correctly but I'm getting this error: SSL configuration is invalid due to No available certificate or key corresponds to the SSL cipher suites which are enabled Some background of what I have done: My cert is from GoDaddy. I generated the CSR from a new keystore (keystore.jks), then imported the resulting certs back into the same keystore and set the keystore password to the same pwd as the GF master password. Then created a new SSL listener in GF and pointed it at my keystore file (which I copied into domains/domain1/config). Set the Nickname to the alias of my cert (which is something liem 'mydomain.org' i.e. the name that I get when I run keytool -list. In my ciphers section in the network listeners page, I leave the defaults in place (empty, which means all ciphers are available I think). In domain.xml I've replaced all instances of s1as to 'mydomain.org'. This is the question: What exactly is causing the error highlighted? I'm guessing it's a mismatch between my listener config and aliases in my keystore, or something similar, but I'm not really sure what. Thanks

• Microphone array support in Windows. Info on performance and compatible hardware?

  - by exinocactus

  It is officially claimed by Microsoft (Audio Device Technologies for Windows), that Windows Vista has an integrated system-level support of microphone arrays for improved sound capturing by isolating a sound source in target direction and rejecting ambient noise and reverberation. In more technical terms, an implementation of an adaptive beamformer. Theoretically, microphone arrays with 2-4 mics can substantially improve SNR under some conditions like speaker in front of the laptop in noisy environment (airport, cafe). Surprisingly, though, I find very little information about commercially-available products supporting these new features. I mean products like portable usb micropone arrays or laptops or flat screens with integrated mic arrays. I could only find info about two laptop models having "noise cancelling digital array microphone". These are Dell Latitude and Eee PC 1008P-KR. Now my questions: Do you have any experience with the Windows beamformer implementation? For instance, in the above mentioned laptops. How well does it work? Are there any tests results available in the net or in print (papers?)? Do you know about other microphone array hardware? What could be the reason why mic array technology didn't get sucess Is there mic arrays support in 'Windows 7'?

• Debian 100% cpu every 30 minutes but not loggable?

  - by user654123

  I have a Debian 7 x64 machine running with Digital Ocean that has every 30 Minutes a 100% cpu usage for about 1 minute. A couple of days ago it stayed there for a couple of hours so the server finally crashed and I had to repair my Mysql databases. The server is a pure webserver running apache2 and Mysql. I tried tracing which processes use the cpu but with no luck. The script I used: #!/bin/sh while true; do ps -A -eo pcpu,pid,user,args | sort -k 1 -r | head -3 >> proclog.txt; echo "\n" >> proclog.txt; sleep 2; done I was monitoring htop as well while this was happening, but the top processess' cpu usage didn't add up to ~15% even though htop's cpu meter showed constant 100%. htop was configured to show all users' processess, user- and kernel-threads. Edit: By stopping Apache2 & Mysql prior to the expected 100% usage I can tell both are not responsible for it. The 100% usage occurred anyway. This is what the graph looked like the past hours:

• Can I use HP Recovery Discs for a different hard drive capacity and make?

  - by Fasih Khatib

  About two years ago I created HP Recovery Discs (3 of them). Now my hard drive has crashed and new one is still a week from delivery. I was reading up on how to reinstall the genuine OS using the Recovery Discs as i was not given any Windows 7 installation discs. I did my bit of research after getting answers from the community on what these discs do and found out on other sites that people experience issues when recovering their OS from the disc. Especially when they change the make or capacity of the harddrive. Unfortunately I had to change the make as the hard drive that came built in has gone out of production. This question is just a part of my checklist to avoid problems when recovering the OS. I have: HP DV4-2126TX (available only in India I guess) I had: Seagate Momentus 320 GB I ordered: Western Digital Scorpio Black 500 GB Windows 7 Home Premium 32-bit Is there a possibility to encounter any problems due to the changed capacity and make? I only want my genuine OS and drivers – not my data. I was told that Disc 1 contained the OS and drivers, and the rest of the discs contained data. I couldn't verify that.

• Can Windows Media Player create playlists based on folder structure?

  - by Chaulky

  Over the years I've carefully molded my digital media collection into a series of folders that make it easy for me to find what I'm looking for. I recently discovered the awesomeness that is streaming video from Windows 7 Media Player to the PS3 so I can watch it on the big screen without all the hassle of hooking the computer up to the TV. The problem is, I totally lose my carefully crafted folder structure and all my videos become one giant mess again... not cool! As a temporary solution, I've created a few playlists for my favorites (Dexter Season 4, Dexter Season 5, Breaking Bad Season 1, etc.). This is a HUGE pain in the a$$. So, is there a way to get Windows Media Player (on Windows 7) to maintain some sort of folder structure based on the location of the actual video files? So if I have my videos sorted into folders by show and season, Media Player will pick that up and let me browse it in the same way. As an alternative answer, I'll accept suggestions for a program that can also stream to PS3 and has this "folder organization" feature.

• Noob with git repository on Windows Storage Server 2008?

  - by HibbyHoo

  I have a Western Digital Sentinel at home running Windows Storage Server 2008 R2 Essentials. I have several git repositories on it for my own personal projects, and have no problem pushing and pulling over my local network. I want to be able to access those repos remotely from anywhere. I am able to log in and remotely access folders and files on it, but I cannot clone repos using the same address. It hangs for a REALLY long time before finally failing with an error: git.exe clone --progress -v "https://myIpAddressHere/Remote/fs/files.aspx?path=%5C%5Cmydevicename%5Cmyreposfolder%5Cmyrepo.git" "D:\repo" Cloning into 'D:\repo'... error: Failed connect to myIpAddress:443; No error while accessing https://myIpAddress/Remote/fs/files.aspx?path=%5C%5Cmydevicename%5Cmyreposfolder%5Cmyrepo.git/info/refs fatal: HTTP request failed git did not exit cleanly (exit code 128) I'm not too privy to networking or web development, and I have only a rudimentary understanding of how to use git (with TortoiseGit).

• Linux can dual display but windows can't?

  - by Mr_CryptoPrime

  I have two monitors, one that is hdmi-to-dvi and the other vga-to-dvi. I have an AMD HD Radeon 6900 series graphics card installed. I got Ubuntu to display dual monitors, but then I restarted for an update and then Ubuntu wouldn't even boot in recovery mode, it just kept cycling forever...displaying something about "timeout: killing [filepath] [hexadecimal]. So I tried booting into windows (7-professional) and it crashed and displayed this after rebooting: IRQL_NOT_LESS_OR_EQUAL, PAGE_FAULT-IN-NONPAGED-AREA. I went into Bios and reverted to the system defaults and ran system restore and it booted ok, but the dvi-to-dvi monitor would not display. I made sure my drivers were updated and catalyst was updated. Also through research discovered only one is for vga and the other is digital only, so I put the vga-to-dvi in the vga slot and so on. Neither windows or catalyst will detect the dvi-to-dvi montior. Any suggestions? Thanks. EDIT: Found out that booting into Ubuntu with only one monitor (using either monitor with either cable) worked perfectly fine. I could then add another monitor and it displays ok. However, it will, out of the blue, suddenly distort the display. At first I thought the computer crashed, but it is something with the video output from the GPU to the monitor because I pushed the power button and it would refresh every 5secs or so and I could see the "Ubuntu will power down in X seconds", even though it was horribly distorted. Any ideas what's causing this?

• How can I get DVDs playing after a Vista to XP change?

  - by Liath

  I replaced my vista install on a Dell Inspiron 1525 with XP and have managed to get most things up and running again however I'm having trouble with playing DVDs. When I try and play a DVD I get the following message: Windows Media Player cannot play this DVD because there is a problem with digital copy protection between your DVD drive, decoder, and video card. Try installing an updated driver for your video card. I have ensured that my drive is configured to play Region 2 discs (I'm in the UK), I've installed the most up to date XP codec pack which makes me think it's a driver issue. In device manager I have got my DVD drivers up to date however under "Other Devices" I'm missing several which sound key: Audio Device on High Definition Audio Bus Modem Device on High Definition Audio Bus Video Controller Video Controller (VGA Compatible) However I've installed all the relevant drivers I can find on the Dell website. The drive itself is working - I've run software from the drive. I'm afraid I am far from a sys-admin so I'm struggling on this one. How can I get my DVDs playing again?

• Windows 7 does not detect my new hard drive?

  - by jasondavis

  I just built a really nice new PC. Some specs... Intel i7-930 CPU ASRock Extreme X58 motherboard with sata 3 and USB 3.0 12gb of G-Skill DDR3 RAM 80gb Intel G2 Solid state drive for Windows 7 and other programs to run on Windows 7 Pro 64bit OS 2 1gb grapghic cards for 4 monitor support Thats the main components. Well today my new 1tb western digital hard drive came which I plan to use for data to preserve the life of my SSD (hopefully). I hooked up it's sata power input and then hooked up it's sata data cable to a sata 2 port on my motherboard, I boot windows 7 and go into my computer and the drive is not showing up with my other drives. I then re-boot again and check again, no luck. I then shut down the PC and open the case back up, I then check my connections and they all look good. I then boot up and I can see the new HD is on and spinning. I then go into my BIOS settings to see if it registers there and it DOES! It shows I have a WD 1tb hard drvie on sata 2 port 6. So I am at a loss of why it is not showing up as an option in windows? Windows acts as if the drive is not there. Please help

• Removing Phantom Registry Entries

  - by shedd

  First, some background: I'm trying to install an HP OfficeJet 6500. I've got the printer setup on my network fine, but the driver software installation on Windows XP (SP3) is a PITA. The installation program keeps dying with the following error: Product: Network -- Error 1324. The folder path 'WD Sync Data' contains an invalid character. WD Sync Data is a program on external Western Digital harddrives, which I used to use on this computer, but no external drive is current mounted. I've searched my registry for those keywords, but haven't found anything. I also ran CCleaner on the registry just to make sure, but no loose ends detected there, either. There are a number of Google results for the error, but no solutions. One post pointed me to the Windows Installer Cleanup Utility, but this utility doesn't even run - it dies with the same error before even starting. Any thoughts on where I could look to clean up this invalid character so I can get the HP installation wizard to successfully run? Many thanks in advance!

• Allow connections to only a specific URL via HTTPS with iptables, -m recent (potentially) and -m string (definitely)

  - by The Consumer

  Hello, Let's say that, for example, I want to allow connections only to subdomain.mydomain.com; I have it partially working, but it sometimes gets in a freaky loop with the client key exchange once the Client Hello is allowed. Ah, to make it even more annoying, it's a self-signed certificate, and the page requires authentication, and HTTPS is listening on a non-standard port... So the TCP/SSL Handshake experience will differ greatly for many users. Is -m recent the right route? Is there a more graceful method to allow the complete TCP stream once the string is seen? Here's what I have so far: #iptables -N SSL #iptables -A INPUT -i eth0 -p tcp -j SSL #iptables -A SSL -m recent --set -p tcp --syn --dport 400 #iptables -A SSL -m recent --update -p tcp --tcp-flags PSH,SYN,ACK SYN,ACK --sport 400 #iptables -A SSL -m recent --update -p tcp --tcp-flags PSH,SYN,ACK ACK --dport 400 #iptables -A SSL -m recent --remove -p tcp --tcp-flags PSH,ACK PSH,ACK --dport 400 -m string --algo kmp --string "subdomain.mydomain.com" -j ACCEPT Yes, I have tried to get around this with nginx tweaks, but I can't get nginx to return a 444 or abrupt disconnect before the client hello, if you can think of a way to achieve this instead, I'm all ears, err, eyes. (As suggested by a user, bringing this inquiry over from http://stackoverflow.com/questions/4628157/allow-connections-to-only-a-specific-url-via-https-with-iptables-m-recent-pote)

• My PC suddenly reboots

  - by ChocoDeveloper

  Yesterday I opened my PC hub (after like, 5 years) to add more RAM and a new HDD. It was full of dust and balls of fluff, so I cleaned it a bit by blowing. I also removed the fan that was attached to the motherboard (I think it's there to cool the processor) and I cleaned it also by blowing and with a paintbrush, then put it back where it was (it had 4 weird plastic screws, it wasn't easy). Then I added 2 x 2Gib of RAM (Kingston 1333MHz), and the new HDD (Western Digital Caviar Blue 1TB SATA 3). I couldn't find another wire like the one my first disk had, which was thicker, but there was one that was more flat, so I plugged it and it worked fine (I also plugged the wire that I think is for the data, which looks like many little wires glued together). I'm running Ubuntu 12.04, and in the new disk I've just installed Windows 7. Between yesterday and today, two reboots ocurred while working on Ubuntu. I haven't used Windows 7 that much so I don't know if it will happen there too. So where can I begin to debug this?

  Hi, I'm trying to set-up a subversion server with apache2/webdav access. I've created the repository and configure Apache according to the official book, and I can see the repository in a webbrowser. The browser shows: conf/ db/ hooks/ locks/ Although clicking any of those links gives an empty xml document like: <D:error> <C:error/> <m:human-readable errcode="2"> Could not open the requested SVN filesystem </m:human-readable> </D:error> I've never used subversion before so I assume this is correct? Anyway, when I try to connect via a command line client, it asks for my password, I give it, then I get the (useless) error message: svn: OPTIONS of 'https://svn.mysite.com': Could not read status line: Secure connection truncated (https://svn.mysite.com) The command I'm using is: svn checkout https://svn.mysite.com/ svn.mysite.com Subversion was installed using Ubuntu's package manager. It's version 1.6.6 on Ubuntu 10.04. My Virtualhost Cofiguration: <VirtualHost 123.123.12.12:443> ServerAdmin [email protected] ServerName svn.mysite.com <Location /> DAV svn SVNParentPath /var/svn/repos SVNListParentPath On AuthType Basic AuthName "Subversion Repository" AuthUserFile /etc/subversion/passwd Require valid-user </Location> # Setup The SSL Certificate Paths SSLEngine On SSLCertificateFile /etc/ssl/certs/mysite.com.crt SSLCertificateKeyFile /etc/ssl/private/dmysite.com.key </VirtualHost>

• Duplicate monitor on highest resolution in Windows 7

  - by AlexanderMP

  I have a monitor with a native resolution of 2560x1440, connected through display port. I also have an AV Receiver connected to the video card via HDMI, to have surround sound in games. All using Radeon HD 5670 (will upgrade soon to HD 7850). The problem is that my computer detects the receiver as a separate monitor, with the highest available resolution of 1920x1080. I have 3 options: Disconnect the second display. But then the sound (digital audio output through video card) also disappears. Duplicate displays. But then my primary monitor resolution is reduced to a maximum of just 1920x1080, that being the maximum of the second monitor. Extend desktop. This is the solution I picked so far, it being the least evil. The problems I face in this situations are 2: I have a blank part of the desktop where I sometimes lose my mouse pointer, so I made the extension small, 640x480, and placed it in a corner; when I turn off the main display, all windows resize to 640x480. In Kubuntu I had the option to duplicate the displays, while keeping the higher resolution. Which was great. I tried overriding using the Win7 netbook hack, but it's not available on non-netbooks. Is there a similar solution for this problem in Windows 7?

• Matched or unmatched drives for RAID arrays?

  - by Will

  Looking around there is conflciting information on this, with some strongly suggesting one or the other. From my understanding the issue with matched drives is that the wear on both drives is more or less the same, so the potential for the second drive failing with or very soon after the first is pretty high. People also claim matched drives give substianatally higher performance however assuming the unmatched drives are more or less the same (eg 2, 1 TB STATA II 7200rpm drives with 32MB cache), would the minor differences between say a Seagate and a Western Digital one (say one has a 128MB/s read rate, and the other a 150MB/s read rate, as well as I guess various other minor differences) actually cause any notable performance loss, ie potentialy worse than two matched 128MB/s drives, or does RAID not really care and give you essentially an optimal solution (eg upto 278MB/s total read speed for RAID 0 and 1) and similar for other RAID with more "unmatched" drives (5 and 1+0 come to mind as possibilities)? Also I couldnt find much info on how this is different on different RAID setups, eg RAID 0 or RAID 1, software or hardware RAID, etc. I'm assuming such things have an effect, and thats it's not all the same for RAID in general?
