• 1080p monitor: connected through VGA - perfect, HDMI - awful

  - by develroot

  When I connect my 23" monitor (1920x1080) to my pc through HDMI, I encourage some problems. It's not full screen That's it. There are ~1cm black borders on right and left side and ~0,5cm black borders on the top and the bottom of the monitor. That's pretty frustrating. I tried adjusting overscan, but I can't mannualy type the % of overscan that I need. I can only select between ex. 8 and 10% in AMD Vision Engine Control center, but what I need is 9%. Next, even if i select 10% and the image fits all the corners, but after log off all the settings are lost and I have to do it again and again. Text, images, everything looks blurry That surprised me a lot. Should'nt HDMI quality be better than VGA's one? When connected through HDMI, the text isn't readable. It's like a very low refresh rate, although i'm running at 60Hz. Also the text has something like little shadows, very very annoying. Are there any tips to get the same quality as with VGA, with HDMI ? (running on integrated ATI Radeon HD4200, which, appearently, is the best card I have ever seen in terms of integrated ones)

• External Dell Display doesn't work with MacBook Pro (2011) after Thunderbolt Firmware Update (1.0 and 1.2)

  - by tom

  Today two Thunderbolt Firmware Updates (1.0 and 1.2) became available for my MacBook Pro (Early 2011). After installing both, my external monitor, a Dell U2713HM, does no longer work. The system detects the display, but the display shows only black. An Apple Thunderbolt display works fine and a MacBook Air can use the Dell monitor without problems. My MacBook Pro can use the Dell monitor just fine when I boot from a USB stick. Therefore, clearly the Thunderbolt Firmware Update seems to be the problem. Does anyone have the same problem? Any solutions or workarounds? I guess there is no way to remove a Thunderbolt Firmware Update once it's installed, right? Update 24.10.2013: Is there no one else with this problem? In the meantime I tried three different cables – none worked. My colleague with the same generation MacBook Pro also can't use my display after installing the firmware update. All colleagues with MacBook Airs and newer MacBook Pros (all didn't receive the firmware update) can use the display. Update 29.10.2013: Wow, ok today my new MacBook Pro Retina 13' (Late 2013) arrived. Guess what, I cannot use the display with it. Only HDMI works – not with the full resolution.

• Unable to Align Layers in Photoshop Properly with CS2

  - by Jonathan Sampson

  Cannot Align Semi-Transparent Items? Windows Vista, Photoshop CS2. Steps to repeat: Create new document Fill a circle on a new layer Drop opacity of filled circle to 10% Create new empty layer below circle layer Merge empty layer with filled circle layer Select entire canvas Attempt to align layers to selectionlayer > align layers to selection > vertical centers I get the following error: Could not complete the Vertical Centers command because there are no layers to be moved. Clearly this is not true, as I'm selecting the layer with the semi-translucent ball on it. Now, if you had tried this same command prior to step 5 (when the layer was at 10% opacity) it would have worked. Is there some way around this problem? I need to move layers around that begin as transparent items, with a layer opacity at 100% where 100% of the layers opacity results in showing objects that are themselves not-very opaque. I've confirmed on another machine that this problem doesn't exist in CS3. I may exist in earlier copies of Photoshop, but I only have access to CS2 (has the problem) and CS3 (does not have the problem).

• Small maximum number of connections on a Linux router

  - by Eugene

  I have a Linux box acting as a router with no iptables or other firewall and no networking applications running on it, just pure router. I've put it in a test environment that generates many TCP connections, each having unique source and destination IP, and those connections go through this router. I'm observing that number of connections successfully created rise to approximately 500 and then no more connections can be created for several minutes, then another 100 connections can be created and there is another pause, and so on. If 10 connections for each source-destination pair are created, then maximum numbers go about 10 times up, so the problem is probably with many connections from different IPs. As traffic is simply routed, it doesn't have to do with number of file descriptors, iptables connection tracking and other things often proposed to check in similar cases. The box has plenty of free RAM and CPU, both NICs are gigabit. The kernel is 2.6.32. I've already tried increasing net.core.*mem_max, net.core.netdev_max_backlog and txqueuelen on both NICs, with completely no effect. What else should I check ? Is there some rate-limit in the kernel itself ?

• Terratec Cinergy Hybrid T USB XS is not recognized anymore on Mac OS X

  - by Gabble

  I have used Terratec Cinergy Hybrid T USB XS for years now, alongside with Elgato EyeTV software. I am a happy and completely satisfied user! Since a couple of weeks the USB sitck stopped working on my MacPro1,1 (OS version 10.6.3): EyeTV does not see any device attached, and actually, the green led on the stick stays off. It is not a USB port fault: I have unplugged any other USB/Firewire device and tried with different USB ports, to no avail (any other USB devices work as expected on any port) I have completely uninstalled EyeTV software, including preferences and system daemons/extensions, rebooted and reinstalled the latest EyeTV. No way. Reset the PRAM. Nope. Checked the Apple System Profiler - USB: No device attached, The MacPro does not see it at all. I need to say that: a) The device worked as a charm even with the latest OS 10.6.x (so it's not a OS upgrade cause). b) I have plugged the Terratec Cinergy Hybrid T USB XS to my MacBook5,1 where EyeTV is not installed and was never installed: The green led on the stick turns on, the growl bubble pops up, and the device is perfectly recognized by the system. Apple System Profiler says (sorry, Italian language): Cinergy Hybrid T USB XS (2882): ID prodotto: 0x005e ID fornitore: 0x0ccd Versione: 1.10 Numero di serie: 061102005755 Velocità: Fino a 12 Mb/sec Produttore: TerraTec Electronic GmbH ID posizione: 0x04100000 Corrente disponibile (mA): 500 Corrente necessaria (mA): 500 At this point I am pretty sure the Terratec stick is not damaged and there is something wrong with my MacPro. I kindly ask you: Is there a way to force my MacPro recognize the USB device? What can I check? Is there something that caches USB connection that can be reset? A OS reinstall would be the very last resort for me. Thanks in advance for any help you will offer!

• Trobleshooting extremely slow opening times in Win7 for documents on Win2k8 server

  - by Mazupan

  Hello. It's hard even to describe my problem. It seems there's only problem with extreme slow openings (up to 10 minutes) on Windows 7 (on XP things works fine) for files that are stored on Windows Server 2008. And now what I discovered up till now. If I open (some files, not all, not allways) .doc and .xls files with doubleclicking it takes up to 10 minutes to finaly open the file. In that time, file seems to be locked for all other users. If I cancel opening, file remains locked for some time. Owner on that files is the one who last wrote changes in them. If I change the owner to larger group, which I am member of file gets opened super fast. When opened file can be saved normaly and fast. That file reopens fast. One other user reports that there is only problem when opening the files for the first time in a day. When he openes first file he has no problems with other files at all (or so he says). He also states that when accessing files from home via VPN he has no such problems with files. And now: anybody has a clue where to start looking? I suppose that is misconfiguration problem. But where? File system? Permissions? DFS? VMWare network config? My setup is as follows: Physical server: HP Prolian ML350 G6 Virtual host: VMWare ESXi 4 Guest: Windows Server 2008 Standard Files are accessed via DFS shares. Please help me. Thanks. Mazupan

• FTP Server upload and filesystem questions

  - by Alex

  I'm a photographer who mainly does event photography. A while ago I bought myself a Nikon WT-4 wireless transmitter, a small device which connects via USB to my Nikon D700 DSLR, and then establishes a WiFi connection to an existing WLAN. It can then upload any pictures I take via FTP to an FTP server somewhere in the network. On my laptop I then have a piece of software which will check a given folder on the disk regularly, this software is smart enough to look at the modified file timestamp, if this timestamp is less than 10 seconds ago, it will not attempt to import the folder and skip the file in this iteration of the import scan. The problem I've discovered seems to be inherent to the FTP protocol, as I have the same problem with Windows 7 built in IIS server, as I do with FileZilla FTP server. When the transmitter starts to upload a file, the FTP server will create a small 300-500 KB file with the correct filename on the disk, but then do nothing with the file until it has completely received the file via FTP. So it seems to create this small dummy file, and then buffer the remainder of the FTP upload until it's finished, and then dump the rest of the file into the dummy file making it the correct size. Problem is, these uploads take about 15-30 seconds depending on reception, but since the folder watch tool will already try to import any file older than 10 seconds, it will always try to import the small dummy files which obviously fails as they're not copmlete yet. Is there any way to 'disable' this behaviour? Ideally I would like my file only to show up once it's been completely uploaded. Or perhaps someone knows another FTP server application (it has to run on win7) which does not show this behaviour?

• 100% CPU when doing 4 or more concurrent requests with Magento

  - by pancake

  Currently I'm having trouble with a server running Magento, it's unbelievably slow. It's a VPS with a few Magento installations on it used for development, so I'm the only one using them. When I do 4 request all 2 seconds after each other I'm finished in 10 seconds. Slow, but still within the limits of my patience. When I do 4 "concurrent" requests, however (opening 4 tabs in a row, very quickly) all four cores go to 100% and stay there for like a minute. How is this possible? I know that there are a lot of possibilities here, so any tips on how to make an Apache/PHP server go faster are also welcome. It used to go a lot faster before, and I've also tried APC, but it kept causing problems (PHP errors, something with memory pools) so I've disabled it. By the way, the Magento cache is off and compiling is also off. I know this makes Magento slower than usual, but I don't think a 60 second response time is normal for any Magento installation. Virtual hardware: 4 Cores and 4096MB RAM Swap is never used (checked with htop) 100GB disk space, of which 10% is in use Software: Debian 6 DirectAdmin and apache custombuild PHP 5.2.17 (CLI) If you need more info, please tell me how to get it, because I probably don't know how. I do know how to use the command line in linux and the usage of quite a few commands, but my experience with managing a server is limited.

• VPS Memory Exchausted Even With Light Settings

  - by user101570

  Linux noob here. I have a 256MB VPS on Ubuntu 11.04 server and when I run "free -m" the result shows all memory being used (including the second line re: buffers/cache). I found this very strange, considering I only have 5 Apache processes running each chewing up about 20MB each. MYSQL is taking up 30MB. To my knowledge, and according to "top", I have no other memory hogs operating. Settings that may be relevant: PHP memory_limit = 32M MYSQL key_buffer = 16M Prefork MPM Maxclients = 10 So when I reviewed these settings, I naturally thought maxclients was too high, so I tried switching it to 5. Now not only does my memory still show as being 100% used, my website loads much, much slower, despite not getting any traffic aside from mine at the moment. I don't understand this. I thought a single Apache process handles all requests from a client received within the "KeepAliveTimeout" window, which I've set to 2 seconds. With my initial config. of 10 maxclients, my page load times are around .3ms, so a single process should handle that no problem, correct? So next I went to an extreme level of 1 for maxclients. My memory is still at 100% usage and my site loads painfully slow. I'm a noob at a complete loss here. According to the many tutorials I've read on basic server setup, I should be good to go. Help! Please! Edit: total used free shared buffers cached Mem: 256 256 0 0 0 0 -/+ buffers/cache: 256 0 Swap: 0 0 0

• How do I change the default ftp folder in MacOS X 10.6?

  - by Wild_Eep

  I'm running WordPress 2.9.1 from a Mac running 10.6.3. WordPress is installed to the /Library/WebServer/Documents folder. WordPress has a feature called AutoUpdate. Clicking an autoupdate button will download and install updated versions of the WordPress software, or third-party plugin tools. It's a convenient way to keep things up to date. WordPress uses FTP to download the files. I've enabled FTP and set up a user account and opened the requisite ports in my firewall for FTP traffic. This doesn't seem to be enough for my self-hosted installation, though. I'm sure this feature was originally designed for someone who has access to a remote shared webserver, and that it's merely a configuration challenge related to the FTP setup. I feel that if I can adjust the initial directory that the FTP service presents to the AutoUpdate feature, everything else will work properly. So, my question is, how do I adjust what folder is presented when a given user connects to a Mac running 10.6.3 via FTP?

• AA doesn't work due to monitor?

  - by MikeQ

  I have a monitor (with TV tuner - Philips 221T1SB), native resolution of 1920x1080, but there is an Overscan in Catalyst. It says from left to right '10%' and '0%', if i set it (all the way to the left) on 10%, i get screen with black borders (you know what i mean), but if i set it to 0%, i get a filled monitor. It does make sense, but why the hell is there such an option? I never had any AA issues before, but now, with this monitor, here they go. I can't find any solution, i have only one lead = overscan, or pretty much anything with the CCC settings. Yes, i almost forgot. After a bit of trying to configure the monitor with remote, i found there is a PC channel option, few other channels, and then a HDMI option. I have monitor through HDMI, but why i get black screen when i select the PC channel? That might be another problem. I tried almost everything. Please guys, give me a hand. I don't want jaggies! CPU: Intel I5-750 @4,0GHz RAM: Corsair Vengeance 8GB 1600MHz GPU: AMD Gigabyte HD 7950 Windforce @1100/1400, 1,174V Motherboard: ASUS P7P55D-E EVO

• Computer making strange sound when turned on, ever since power outage

  - by Dot NET

  Recently we experienced a power outage, and the PC was off. However, once the power came back, I switched on the PC and heard a strange noise - almost as if the hard disk or fans were struggling to work. I can't really describe the sound, but it's a laboured, loud sound almost like a jack-hammer. This has been persisting ever since the power outage, however the noise stops after around 10 minutes or so, and doesn't start again until the computer is turned off and on again. At first I thought it had something to do with the HDD, but all my files are intact, chkdsk did not report any issues and performance is 100% unchanged, even in games (so the gfx card is fine, and so is the HDD most likely). My PC setup basically has around 3 cooling fans, but I'm not sure if it's one of these either as the noise actually stops after 10 minutes or so, and if I leave the PC on for 4 hours (for example) the noise never starts again. It's there solely when turning on the PC. I haven't got a UPS, and it's important to note that the computer was not on when the power went out - it was merely plugged in. I then promptly unplugged the PC once the power was out, and only plugged it in again when the power came back. Could it be the power supply? Unfortunately I can't open my tower as I would void the warranty. Are there any tests which I could carry out without voiding the warranty?

• Basic IPTables setup for OpenVPN/HTTP/HTTPS server

  - by Afronautica

  I'm trying to get a basic IPTables setup on my server which will allow HTTP/SSH access, as well as enable the use of the server as an OpenVPN tunnel. The following is my current rule setup - the problem is OpenVPN queries (port 1194) seemed to be getting dropped as a result of this ruleset. Pinging a website while logged into the VPN results in teh response: Request timeout for icmp_seq 1 92 bytes from 10.8.0.1: Destination Port Unreachable When I clear the IPTable rules pinging from the VPN works fine.

• Do I need to update some of my Debian Squeeze software?

  - by stan31337

  I have installed Debian 6, and LAMP stack from squeeze repository (default). After upgrading Apache 2.2.16 from unstable repository to 2.2.22, thanks to this post - how to upgrade already installed apache2 on debian (lenny) I'm thinking to upgrade all other software packages that I've previously installd from squeeze repository. Should I upgrade them to the ones from unstable repository? Should I upgrade all of them or just selected ones? Here's the list: * arno-iptables-firewall 1.9.2.k-4 >> 2.0.1.c-1 * bind9 1:9.7.3.dfsg-1~squeeze6 >> 1:9.8.1.dfsg.P1-4.2 * php-apc 3.1.3p1-2 >> 3.1.13-1 * fail2ban 0.8.4-3+squeeze1 >> 0.8.6-3 * exim4 4.72-6+squeeze2 >> 4.80-4 * altermime 0.3.10-4 >> 0.3.10-7 * rrdtool 1.4.3-1 >> 1.4.7-2 * vsftpd 2.3.2-3+squeeze2 >> 3.0.0-4 Also I would like to ask how to upgrade 5.3.3 5.3.16, unstable repository has 5.4.x versions only, I don't think I'm ready to move from 5.3 to 5.4 yet. Actually I'm a newbie in Linux, and after Windows experience I have a paranoidal idea to update software to the latest release. I'd be glad for any suggestions and recommendations! Thank you very much!

• How to show what will be updated next pull?

  In SVN, doing svn update will show a list of full paths with a status prefix: $ svn update M foo/bar U another/bar Revision 123 I need to get this update list to do some post-process work. After I have transferred the SVN repository to Git, I can't find a way to get the update list: $ git pull Updating 9607ca4..61584c3 Fast-forward .gitignore | 1 + uni/.gitignore | 1 + uni/package/cooldeb/.gitignore | 1 + uni/package/cooldeb/Makefile.am | 2 +- uni/package/cooldeb/VERSION.av | 10 +- uni/package/cooldeb/cideb | 10 +- uni/package/cooldeb/cooldeb.sh | 2 +- uni/package/cooldeb/newdeb | 53 +++- ...update-and-deb-redist => update-and-deb-redist} | 5 +- uni/utils/2tree/{list2tree => 2tree} | 12 +- uni/utils/2tree/ChangeLog | 4 +- uni/utils/2tree/Makefile.am | 2 +- I can translate the Git pull status list to SVN's format: M .gitignore M uni/.gitignore M uni/package/cooldeb/.gitignore M uni/package/cooldeb/Makefile.am M uni/package/cooldeb/VERSION.av M uni/package/cooldeb/cideb M uni/package/cooldeb/cooldeb.sh M uni/package/cooldeb/newdeb M ...update-and-deb-redist => update-and-deb-redist} M uni/utils/2tree/{list2tree => 2tree} M uni/utils/2tree/ChangeLog M uni/utils/2tree/Makefile.am However, some entries having long path names are abbreviated, such as uni/package/cooldeb/update-and-deb-redist is abbreviated to ...update-and-deb-redist. I deem I can do with Git directly, maybe I can configure git pull's output in special format. Any idea?

• How do you enable webcam support in Facebook for Ubuntu 10.04?

  - by Jonathan

  I think I have finally arrived at an insolvable equation: Chromium v.7 + Ubuntu 10.04 + Sun Java 6 + Webcam + Facebook + Flash 10 = non-functional All of those items listed above are potential points of failure in this situation, and any help narrowing them down would be fantastic. I am simply trying to enable webcame support directly through Facebooks website. Forum searches and the usual googling turn up few posts related to this specific equation. Two of the major suggestions include: 1) Installing the Sun (I refuse to say oracle sob)-provided Java implementation instead of the OpenJDK normally installed in Ubuntu. And yes, after installing it, I did update all my default supports to use the sun commands over the openjdk. 2) Somehow enabling Facebook as a permitted site to access my webcam using Flash settings. I have not been able to explore option 2 because I cannot find a way to adjust the Flash settings in chromium 7. Other factors that do not help include the fact that I am pretty sure facebook changes its webcam interface every 10 seconds just to keep troubleshooters and support personnel on their toes. If anyone has a OTP that informs us of the next shift in the app, a leak would be greatly appreciated!

• Windows Server wbadmin recover with commas

  - by dlp

  I want to do a recovery of files with commas in their names from the command line, ala: wbadmin start recovery -version:10/01/2013-12:00 -itemType:File -overwite:Overwrite -quiet "-Items:C:\Path\To\File, With Comma.txt,C:\Path\To\File 2, With Comma.txt" So there are two files: C:\Path\To\File, With Comma.txt C:\Path\To\File 2, With Comma.txt The problem is wbadmin assumes commas separates each file, so it sees 4 files specified instead of 2. I've tried putting a \ in front of commas that are part of the file names like so: wbadmin start recovery -version:10/01/2013-12:00 -itemType:File -overwite:Overwrite -quiet "-Items:C:\Path\To\File\, With Comma.txt,C:\Path\To\File 2\, With Comma.txt" but it doesn't work, it just says there's a syntax error. The documentation on Technet doesn't seem to mention anything that'll help either. OS is Windows Server 2008 R2. A clarifying comment: I've changed the file names to be different than the actual names to be less revealing, but I also see I dumbed it down too much. The comma can occur either in the file name itself like C:\Path\To\File, With Comma.txt' or in the path to the file, like:C:\Path, To\Other\File.txt`.

• Connect USB hard drive to wireless router on RJ45 port? Possible?

  - by lawphotog

  just a quick story behind. I was trying to set up wireless networked hard drive at home. My wireless router doesn't take USB. I am considering few options. First i was considering to get something like WD My Cloud. My router is an old one provided by service provider. It only has 10/100 Ethernet. WD My Cloud has Gigabit interface. So unless i changed a new router, data transfer will be slow. So upgrading the router is a must if i want fast transfer speed. Plus I already own an external hard drive with USB 3.0 interface. So if I get a router like Netgear D6300, i can get a decent speed wireless shared drive at home. And i can use my existing HDD instead of WD My Cloud. But the router isn't cheap so I am saving up for that. In the meantime I found out the existence of USB to RJ45 adaptor. I read the reviews and some say it works for them and for some don't. They didn't really say what they were trying to do so I'm confused. So if i bought an adaptor like this, can i connect my existing HDD (USB) with my existing router (RJ45) and use it as a shared drive for data transfer? I know it will be slow as the adaptor will only have USB 2.0 and 10/100 for Ethernet. But it's fine as it's for temporary until i got my new router.

• VPS goes slow at more than 20 users online at the same time

• How large is the performance loss for a 64-bit VirtualBox guest running on a 32-bit host?

  - by IllvilJa

  I have a 64-bit Virtualbox guest running Gentoo Linux (amd64) and it is currently hosted on a 32-bit Gentoo laptop. I've noticed that the performance of the VM is very slow compared to the performance of the 32-bit host itself. Also when I compare with another 32-bit Linux VM running on the same host, performance is significantly less on the 64-bit VM. I know that running a 64-bit VM on a 32-bit host does incur some performance penalties for the VM, but does anyone have any deeper knowledge of how large a penalty one might expect in this scenario, roughly speaking? Is a 10% slowdown something to expect, or should it be a slowdown in the 90% range (running at 1/10 the normal speed)? Or to phrase it in another way: would it be reasonable to expect that the performance improvement for the 64-bit VM increases so much that it is worth reinstalling the host machine to run 64-bit Gentoo instead? I'm currently seriously considering that upgrade, but am curious about other peoples experience of the current scenario. I am aware that the host OS will require more RAM when running in 64-bit, but that's OK for me. Also, I do know that one usually don't run a 64-bit VM on a 32-bit server (I'm surprised I even got the VM started in the first place) but things turned out that way when I tried to future proof the VM I was setting up and decided to make it 64-bit anyway.

• Strategy for Incremental Datasource fetchings in Excel

  - by user1352530

  I am in an scenario with a table that is refresh by a third app every week. I need to keep accumulating all data in Excel, using an ODBC connection to the database. I am wondering Approach 1: Is there a way to force Excel to append results for every update (this update would be triggered according to a parameter that indicates week)? I tried to define the table for which the connection loads using a dynamic reference but once is anchored first time, table position is never redefined Approach 2: Use an ETL to accumulate all weekly results into a staging table and then connect Excel to it in real time. But, I would need a mechanism for caching old data, as I cannot grow exponentially the time Excel opens. Imagine after 10 years, Excel would need to update at opening 10 years fo data before showing it. Is there a way to store already fetched data and increment it at real time (when book is opened) by selecting new data (with a query/filter of something) Thanks EDIT: Maybe it's better to ask it that way: What is the optimal strategy for a table that keeps growing and needs to be read in real time by Excel? I just don't want to fetch absolutely all data after some months...

• How do you enable webcam support in facebook for ubuntu 10.04?

  - by Jonathan

  I think I have finally arrived at an insolvable equation: Chromium v.7 + Ubuntu 10.04 + Sun Java 6 + Webcam + Facebook + Flash 10 = non-functional All of those items listed above are potential points of failure in this situation, and any help narrowing them down would be fantastic. I am simply trying to enable webcame support directly through Facebooks website. Forum searches and the usual googling turn up few posts related to this specific equation. Two of the major suggestions include: 1) Installing the Sun (I refuse to say oracle sob)-provided Java implementation instead of the OpenJDK normally installed in ubuntu. And yes, after installing it, I did update all my default supports to use the sun commands over the openjdk. 2) Somehow enabling Facebook as a permitted site to access my webcam using Flash settings. I have not been able to explore option 2 because I cannot find a way to adjust the Flash settings in chromium 7. Other factors that do not help include the fact that I am pretty sure facebook changes its webcam interface every 10 seconds just to keep troubleshooters and support personnel on their toes. If anyone has a OTP that informs us of the next shift in the app, a leak would be greatly appreciated! Cheers!

• Quickly close all Word and Excel instances?

  - by dyenatha

  Suppose I open 10 Word files and 10 Excel files and make no changes, how do I quickly taskkill all at once? Because I must repeat several attempts to replicate race, I'm hoping for a command-line solution. I'm willing to try PowerShell and cygwin (1.5) if necessary. The OS is Windows XP SP3 with current patches (still IE7). I tried "taskkill /pid 1 /pid 2 /t" where 1 is PID of EXCEL.EXE and 2 is PID of WINWORD.EXE, but it closed only 1 window of each program. I'm trying to replicate a race where an add-in for Microsoft Office 2007 fails to exclusive-lock one of its own files, which caused the 2nd Office program to stop exiting with a warning: System.IO.IOException: The process cannot access the file 'C:\Documents and Settings\me\Application Data\ExpensiveProduct\Add-InForMicrosoftOffice\4.2\egcred' because it is being used by another process. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options) at System.IO.StreamWriter.CreateFile(String path, Boolean append) at System.IO.StreamWriter..ctor(String path, Boolean append, Encoding encoding, Int32 bufferSize) at System.IO.StreamWriter..ctor(String path, Boolean append, Encoding encoding) at System.IO.File.WriteAllText(String path, String contents, Encoding encoding) at ExpensiveProduct.EG.DataAccess.Credentials.CredentialManager.SaveUserTable() at ExpensiveProduct.OfficeAddin.OfficeAddinBase.Dispose(Boolean disposing) at ExpensiveProduct.OfficeAddin.WordAddin.Dispose(Boolean disposing) at ExpensiveProduct.OfficeAddin.OfficeAddinBase.OnHostShutdown() at ExpensiveProduct.OfficeAddin.OfficeAddinBase.Unload(ext_DisconnectMode mode)

• Windows 7 breaks even in safe mode

  - by delenda

  Hi, I have a Dell XPS M1730 with Windows 7 installed. I noticed last night that after a few hours of use, the fans kicked into full and I couldn't do anything without it taking forever. Minimising windows, opening device manager or even opening process explorer took minutes and a game install I had just started took nearly 4 hours to complete. When procexp finally loaded, the refresh was so slow that it was mostly useless. From what I could gather, it was reporting 60% idle processes with procexp using nearly 40%. There were no hardware interrupts listed. When I rebooted, the problem went away for about 10 minutes and then the same thing happened. The issue persists in safe mode and even after I removed the graphics drivers, which have been an issue in the past, it still happens. Icons flash quite quickly on the desktop periodically and screen refresh is painfully slow. When booting now, the fans kick in to full as soon as the windows logon box comes up and it's taking 10 minutes to bring the desktop up. Chkdsk reports nothing and the raid check says that everything is fine. I'm thinking hardware failure, probably HDD but wanted some other opinions. I'm planning to try a linux live cd to see if it works without using the hard disks. If anyone has any input, it would be greatly appreciated. Delenda

• Why is my rsync so slow?

  - by iblue

  My Laptop and my workstation are both connected to a Gigabit Switch. Both are running Linux. But when I copy files with rsync, it performs badly. I get about 22 MB/s. Shouldn't I theoretically get about 125 MB/s? What is the limiting factor here? EDIT: I conducted some experiments. Write performance on the laptop The laptop has a xfs filesystem with full disk encryption. It uses aes-cbc-essiv:sha256 cipher mode with 256 bits key length. Disk write performance is 58.8 MB/s. iblue@nerdpol:~$ LANG=C dd if=/dev/zero of=test.img bs=1M count=1024 1073741824 Bytes (1.1 GB) copied, 18.2735 s, 58.8 MB/s Read performance on the workstation The files I copied are on a software RAID-5 over 5 HDDs. On top of the raid is a lvm. The volume itself is encrypted with the same cipher. The workstation has a FX-8150 cpu that has a native AES-NI instruction set which speeds up encryption. Disk read performance is 256 MB/s (cache was cold). iblue@raven:/mnt/bytemachine/imgs$ dd if=backup-1333796266.tar.bz2 of=/dev/null bs=1M 10213172008 bytes (10 GB) copied, 39.8882 s, 256 MB/s Network performance I ran iperf between the two clients. Network performance is 939 Mbit/s iblue@raven $ iperf -c 94.135.XXX ------------------------------------------------------------ Client connecting to 94.135.XXX, TCP port 5001 TCP window size: 23.2 KByte (default) ------------------------------------------------------------ [ 3] local 94.135.XXX port 59385 connected with 94.135.YYY port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 1.09 GBytes 939 Mbits/sec
