• System randomly freezes yet mouse still moves

  - by user784446

  This problem has lasted for the past 48 hours. The first time it happened, a program I was running stopped responding, so I tried to end it from task manager. The processes at first were listed fine until hovered upon. Eventually, despite the mouse still being able to move, after a few persisting clicks the mouse finally stopped moving. The screen went blank shortly thereafter. The second time it occurred, items on the screen stopped responding - hovering over the taskbar or such wouldn't elicit a response. Sound would still play however. Eventually, the mouse became unresponsive and the system restarted itself. I suspect that it may be a problem of my SSD drive. After looking through some Google search results, I downloaded HDTunePro to determine if there's a problem with the drive. Results returned a problem of reallocated sector count. An error scan also revealed 48 bad sectors. Also, an attempt to backup the contents of the most important areas of the drive returned a few explorer "Error: cannot read source from disk" errors. Should I ditch the drive and use another drive or is there anything that can be done to repair the drive? SSD: OCZ Petrol 64gb CPU: AMD Athlon II X4 640 RAM: Generic 3GB DDR2 Motherboard: Gigabyte MA74GM-S2H OS: Windows 7 Ultimate x64 Thanks!

• Kickstarting an Ubuntu Server 10.04 installation (DHCP fails)

  - by William

  I'm trying to automate the network installation of Ubuntu 10.04 LTS with an anaconda kickstart and everything seems to running except for the initial DHCP autoconfiguration. The installer attempts to configure the install via DHCP but fails on its first attempt. This brings me to a prompt where I can retry DHCP and it seems to always work on the second attempt. My issue is that this is not really automated if I have to hit retry for DHCP. Is there something I can add to the kickstart file so that it will automatically retry or better yet not fail the first time? Thanks.

• tomcat vs FULL J2EE Solutions

  - by jrhickey

  We are getting ready to make a major revision in our Web Application architecture which currently is running on JBoss 4.2. At first we were looking at moving from 4.2 to JBoss 6 but after some research tomcat may be a better solution for us. My first question is their anything that JBoss can do that tomcat cannot do assuming you are using the correct plugins. We do not really use EJB's in our solution and it would appear there are simple plugins for web services, JMX and other features. Tomcat appears to have much better support, faster upgrade cycles and many, many books. Since there is less to the system it also seems much easier to support from an admin point of view. What am I missing? The main features we want to enable are better clustering support and session replication / persistence. We will consider other application servers as well such as Glassfish / Geronimo. quote form a web article: Apache Tomcat is the world’s most widely used web application server, with over one million downloads per month and over 70% penetration in the enterprise datacenter. Tomcat is used to power everything from simple one server sites to large enterprise networks.

• Public Folders - Delete Public Folders from 2003 after migrating to 2010 (via Adsiedit) - safe?

  - by HeavenCore

  Similar Question: How do I delete a public store in Exchange 2003? We are ready to remove our Exchange 2003 server after having migrated all public folders and mailboxes to 2010. We ran for a week with the exchange 2003 server shutdown and everything seemed to work. When I try to delete the PF database from 2003 it says it contains replicas. Whilst migrating i only had one was sync working (from 2003 to 2010) so i believe that 2003 hasn't received the responses from 2010 saying replica removed. When I look in Public folders on the 2003 box none are listed, when i look in PF Instances they are all listed. I know everything has moved to the 2010 server and I know 2010 is not showing the 2003 server as a replica for any folders. I am looking to use ADSI edit to remove the Public folder database from the 2003 server, but want to ensure i am going to delete the right thing so that they do not get deleted from the 2010 database. Should i delete configuration, Services, Microsoft Exchange, Company Name, Administrative groups, First administrative group, Servers, Server name, Information store, First storage group, public folder store (Server name)? Or something else? I have checked and the only public folder with the old exchange server listed as a replica is SYSTEM CONFIGURATION. Thanks in advance.

• Windows 7 boot manager not localized on UEFI systems

  - by Massimo

  I originally posted this on SuperUser because I discovered this behaviour on my home computer, but this seems to be a general issue on UEFI systems, thus I'm posting here too; I also hope someone here can shed some light on what's going on. Italian version of Windows 7 x64 SP1, same installation media used for both situations. When running on BIOS systems, the boot manager is fully localized, both for the loading screen and for the F8 boot menu. When running on UEFI systems, the boot manager always runs in English, even if it's correctly configured to use the it-IT locale, as BCDEDIT clearly shows: Windows Boot Manager -------------------- identificatore {bootmgr} device partition=\Device\HarddiskVolume1 path \EFI\Microsoft\Boot\bootmgfw.efi description Windows Boot Manager locale it-IT inherit {globalsettings} default {current} resumeobject {9ef36aa6-4188-11e3-909d-d32f0c3871c8} displayorder {current} toolsdisplayorder {memdiag} timeout 30 Caricatore di avvio di Windows ------------------- identificatore {current} device partition=C: path \Windows\system32\winload.efi description Windows 7 locale it-IT inherit {bootloadersettings} recoverysequence {9ef36aa8-4188-11e3-909d-d32f0c3871c8} recoveryenabled Yes osdevice partition=C: systemroot \Windows resumeobject {9ef36aa6-4188-11e3-909d-d32f0c3871c8} nx OptIn I also noticed something strange here; the motherboard setup shows "Windows Boot Manager" as the main boot option, while the actual boot disk is listed as the second one. Looks like the Windows Boot Manager is actually being loaded from somewhere else than the first partition of the first disk... what's going on here? Update I've also checked the EFI boot manager using bcdedit /enum FIRMWARE. That one looks correctly localized, too: Boot Manager per firmware --------------------- identificatore {fwbootmgr} displayorder {bootmgr} {9ef36aa4-4188-11e3-909d-d32f0c3871c8} {a30e8550-47e4-11e3-9ad1-806e6f6e6963} timeout 1 Windows Boot Manager -------------------- identificatore {bootmgr} device partition=\Device\HarddiskVolume1 path \EFI\Microsoft\Boot\bootmgfw.efi description Windows Boot Manager locale it-IT inherit {globalsettings} default {current} resumeobject {9ef36aa6-4188-11e3-909d-d32f0c3871c8} displayorder {current} toolsdisplayorder {memdiag} timeout 30 Applicazione firmware (101fffff) ------------------------------- identificatore {9ef36aa4-4188-11e3-909d-d32f0c3871c8} description CD/DVD Drive Applicazione firmware (101fffff) ------------------------------- identificatore {a30e8550-47e4-11e3-9ad1-806e6f6e6963} description Hard Drive

• virtual host settings fail on multiple sites

  - by Ricalsin

  Wow. I'm puzzled. On my ubuntu system I've setup an apache2 server and configured three virtual hosts in the /etc/apache2/sites-available directory. a2ensite to symbolic link the sites-enabled. The first two work great; a simple url of localhost.mysitenames.com works great for the first two sites, both finding their DocumentRoot and Directory paths. The third always generates a Bad Request (Invalid Hostname) response. No server error.log as it never hits it. I've copied/pasted the working vhost files, made the minor changes to the ServerName, DocumentRoot and Directory and the same problem persists. I always "sudo /etc/init.d/apache2 restart" whenever I make a change. I've cleared the browser cache as well. No love. There's not a limit to the number of sites you can host, right? My goal was a localhost development environment with the expectation I can run any number of websites locally before pushing them to a live server. Any thoughts on how to debug this? Or, just a simple solution I am missing?

• S.M.A.R.T. broken sectors

  - by Jeffrey Vandenborne

  Recently I received my hard drive (LaCie) that I've sent away for warranty, my disk failed, and I used Palimpsest Disk utility to check if anything was wrong in the S.M.A.R.T Status. And it said that there were a few broken sectors. So the next day, I went to the store and told the story. 4 weeks later I actually got my drive back. The first thing I did was plugging it in and starting the disk utility, and weirdly it showed me pretty much the exact same things, even the values of most tests were the same as they were before when my drive broke. The serial number is different though, but it does show a very peculiar value. Now I'm wondering, I'm almost sure it's the exact same drive and it still says I've got broken sectors, does it just say that because it has been cached in the drive somewhere while LaCie DID actually fix it? Or should I run the extended self test (which seems to take hours) first? Also I've tried the smartctl command tool, it says the drive has smart support, but it doesn't show anything, it says that it's enabled, but then it says that it's disabled, picture below The picture of the Disk utility: Thanks in advance

• Is there an Installer Analyser tool that can list what Registry Keys will be created?

  - by EvoGamer

  I can think of 3 ways to achieve my goal: Create a clean VPC, install a given piece of software, and compare the before and after states. Somehow reverse-engineer the installer. Somehow redirect the output of the installer in question so that all registry calls and copy/move file commands are recorded, but not executed. The first option can be done manually, or potentially automated, but I feel it's rather OTT for my needs. The second could cause all sorts of licencing issues, not to mention it may not always return a correct result. Also, without delving into hex editing, I can't think of a way that it would be possible to do manually (some installers - eg Anti-Virus software - may react unfavourably on automated attempts to investigate the installer). The third option shows the most promise, although if the first could be stripped down into a lightweight throwaway environment, it would work pretty much the same way. However, I'm not sure how to do it. So my question is: What tools are available (if any) and/or how could I find out this information manually? I'm not looking to reverse-engineer anything (if I can help it), but I just want to know exactly what changes are being made to my PC by a given piece of software.

• Allow SFTP in iptables

  - by Kevin Orriss

  I have just purchased a VPS from linode and am going through the setup guide. I have everything running (apache2, php, mysql etc) but I am being denied access via SFTP when using fileZilla to upload a file. Now this is my second time installing the server as I missed a section out the first time. I was able to connect to my server through SFTP on filezilla the first time and the thing I missed out was adding a new user and editing the iptables in the firewall. So it would seem that the guide I have been following has blocked SFTP but allowed SSH. Here is the iptables file: *filter # Allow all loopback (lo0) traffic and drop all traffic to 127/8 that doesn't use lo0 -A INPUT -i lo -j ACCEPT -A INPUT ! -i lo -d 127.0.0.0/8 -j REJECT # Accept all established inbound connections -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # Allow all outbound traffic - you can modify this to only allow certain traffic -A OUTPUT -j ACCEPT # Allow HTTP and HTTPS connections from anywhere (the normal ports for websites and SSL). -A INPUT -p tcp --dport 80 -j ACCEPT -A INPUT -p tcp --dport 443 -j ACCEPT # Allow SSH connections # # The -dport number should be the same port number you set in sshd_config # -A INPUT -p tcp -m state --state NEW --dport 22 -j ACCEPT # Allow ping -A INPUT -p icmp -m icmp --icmp-type 8 -j ACCEPT # Log iptables denied calls -A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: " --log-level 7 # Reject all other inbound - default deny unless explicitly allowed policy -A INPUT -j REJECT -A FORWARD -j REJECT COMMIT All I would like is a line I need to put in there which allows SFTP over port 22. Thank you for reading this.

• How to back up initial state of external backup drive?

  - by intuited

  I've picked up an HP Simplesave external drive. It comes with some fancy software that is of no use to me because I don't use Windows. Like many current consumer-targeted backup drives, the backup software is actually contained on the drive itself. I'd like to save the drive's initial state so that I can restore it if I decide to sell it. The backup box itself is somewhat customized: in addition to the hard drive device, it presents a CDROM-like device on /dev/sr0. I gather that the purpose of this cdrom device is to bootstrap via Windows autoplay the backup application which lives on the disk itself. I wouldn't suppose any guarantees about how it does this, so it seems important to preserve the exact state of the disk. The drive is formatted with a single 500GB NTFS partition. My initial thought was to use dd to dump the disk (/dev/sdb) itself, but this proved impractical, as the resulting file was not sparse. This seemed to be because the NTFS empty space is not filled with zeroes, but with a repeating series of 16 bytes. I tried gzipping the output of dd. This reduced to the file to a manageable size — the first 18GB was compressed to 81MB, versus 47MB to tarball the contents of the mounted filesystem — but it was very slow on my admittedly somewhat derelict Pentium M processor. The time to do that first 18GB was about 30 minutes. So I've resorted to dumping the disk state and partition data separately. I've dumped the partition state with sfdisk -d /dev/sdb > sfdisk.-d.out I've also created a compressed image of the NTFS partition (the only one on the disk) with ntfsclone --save-image --output - /dev/sdb1 | gzip -c > ntfsclone.img.gz Is there anything else I should do to ensure that I can restore the precise original state of the drive?

• Unexpected media key behavior on new Acer Aspire

  - by Morgan May

  I'm having weird issues with the media keys (play/pause, previous, next, etc.) on a new Acer Aspire laptop. This is the first Acer I've owned and also my first Windows 7 computer, so I'm not sure whether the behavior is a result of some hidden Acer process that I haven't rooted out yet, or some Windows 7 option that I'm not aware of, or something else. I'm experiencing two issues that I suspect are related. Both problems are intermittent but happen more often than not. The media player I'm using is Winamp. I'm pretty sure I've had the same problem when using other media players, but when I tried to verify that before posting this, I only had the problems with Winamp. Because the problems are intermittent, I'm not sure if that's significant. 1) When I press the Play/Pause media key, in addition to playing or pausing the media player, it brings up a little menu in the center of the screen that lists my removable drives (CD/DVD, USB drives, etc.). To make the menu go away I have to either click away from it or hit Escape. Selecting a drive on the menu doesn't seem to do anything. 2) When I press the Previous or Next media keys, it skips 2+ tracks instead of just one (the exact number seems to vary). I've poked around all the control panel options that I can find, and looked through all the utilities that came with the computer with no luck. There's nothing that I can find in the (very slim) documentation, either. I have a hunch that the problem is caused by whatever utility manages global hotkeys, but I haven't found any way to configure that. Any guidance would be greatly appreciated. UPDATE: It looks like Winamp was the culprit. I did have the problem when using other media players, but when I uninstalled Winamp, the problem went away. I'd like to use Winamp, but I can survive with other players.

• #550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

  - by gtaylor85

  I've searched serverfault and found this question pop-up quite a bit. Unfortunately others problems aren't exactly like mine, and because I'm a true beginner I wanted some more "specific to me" help. If you don't mind. I just set-up a new computer for a user. Copied over her auto-populate and archive emails. Her email, for the most part, works fine. But when she tries to send anything to [email protected] she gets the #550 5.1.1 error. If she uses the exchange webapp she does not have the issue. I can send email to BSMITH, and so can everyone else. The user, as far as I can tell from the EMC reports, is the only person having emails sent back to them and only from BSMITH. I have googled the crap out of this, and attempted some of the solutions to no avail. I've looked for the bmith account in the disabled accounts and copied and attempted to add "IMCEAEX-_O=CHILD+20STUDY+20CENTER_OU=FIRST+20ADMINISTRATIVE+20GROUP_CN=RECIPIENTS_CN=BSMITH@mydomain.com" as an X500 email. I honestly am just following instructions though and I don't really understand what it is I'm doing. Diagnostic information for administrators: Generating server: FS2.FS1D.local IMCEAEX-_O=CHILD+20STUDY+20CENTER_OU=FIRST+20ADMINISTRATIVE+20GROUP_CN=RECIPIENTS_CN=BSMITH@mydomain.com #550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ## BTW I love this site and only found out about it a few weeks ago. My girlfriend now loves the photo.stackexchange. So thanks for such a helpful community.

• Issue with a secure login - Why am I being redirected to the insecure login?

  - by mstrmrvls

  Im having some issues getting a website working at my place of work. The issue was rasised when a "double login" occurred from the secure login site. The second login was actually being prompted by the HTTP domain and not HTTPS. In essence the situation is like this: The user navigates to https://mysite.com/something The login prompt pops up Enter username and password The user is presented with ANOTHER login prompt (IE will say its insecure, and the address bar reflects that) If the user puts in their password the insecure one, they will login to the insecure site. if they hit cancel it will present them with a 401 page Navigating back to https://somesite.com/something will by pass the login prompt and log them in to the secure site automatically (cookie maybe) I'm a bit confused to why the user isnt being logged in properly the first time (redirected to non-ssl) but any consecutive login will be okay? I've been trying to use fiddler to see what is happening after the user puts in their password the first time and trying to get fiddler to automatically login to the site (with no luck) I believe the website in question is using Basic Digest authentication. Thanks for any help

• Strange Domain name under the same IP Address

  - by Mike Chip

  There's something really weird happening in my server. But first things first: I wanted to have my website and chose the domain name "myowndomain.com", Now on my domain registrar I point "myowndomain.com" to the address of my recently setup VPS, let's say 50.50.50.50 So I installed everything I needed to run my website, and I started to notice strange queries coming from different IP Addresses. Like these [client 123.123.123.123] File does not exist: /var/www/html/api, referer: http://www.strangedomain.com/api/manyou/my.php [client 456.456.456.456] File does not exist: /var/www/html/api, referer: http://www.strangedomain.com/api/manyou/my.php or like this (Really a long line, I cut some things) GET /?s=vod-show-id-22-area-%E5%85%B6%E4%BB%96-language-%E9%9F%A9%E8%AF%AD.html HTTP/1.1" 301 295 "http://v.strangedomain.com/?s=vod-s ...[cut]... spider" That above is happening the most. The 'strangedomain.com' returns the same IP address of my VPS which my website is hosted on. The whois of such domain shows it's registered to a chinese. But the street name didn't look so right (like a huge single word), so I think all of that info might be fake, but still might be a chinese. I also noticed that all 'clients' trying to access the 'strangedomain.com' is coming from china. If I type in the browser 'strangedomain.com', I see my website. I'm worried, because my website is actually an e-commerce. I don't know if 'strangedomain.com' WAS a website on 50.50.50.50 in the not so far past, or if it's something else.

• Using a degrading corrupted hard disk with a brand new one. Is this ok?

  - by EApubs

  My old 500 GB hard drive started to give bad sectors. Its slowly going down. So, I bought a new 1TB Seagate drive. I first attached the 500GB drive as the first primary drive and installed Windows. I want Windows boot loader to be placed in the old drive so it won't conflict with the Linux system. But the actual Windows system (Including the C drive) is placed on my new hard drive. After this, I attached the new drive as the primary and installed Linux. Now if I want to re install windows, I can do it without any issues by simply setting the old drive as the primary. So the Linux system will be untouched. But is it a good idea to set things like this? Will the old degrading drive have an impact on the new one? The old drive is slower than the new one. Won't I be able to get the maximum speed out of the new drive even when its used to install everything (including the OS)? PS : When I ran the Windows Experience Index, I was using the old drive as the primary. Did it got the hard drive ratings from the old drive? What if I run it now with the new drive as the primary?

• can't change wallpaper real time regedit commands

  - by itagomo

  i'm a first time 'SuperUser' poster .. what i want is to programatically change Desktop Wallpaper every few hours .. i'm using a batch file (.bat) and don't want to use other languages or programs, just the pre-installed stuffs with Windows XP .. i've already made my script that will modify values in the Registry reg add "HKCU\Control Panel\Desktop" /v Wallpaper /d "C:\Pictures\picture1.jpg" but it's not taking effect real time even with this command: RUNDLL32.EXE USER32.DLL,UpdatePerUserSystemParameters ,1 ,True need to reboot first to take effect. if i'm going to use Display Properties, it'll show at once. what i've noticed is that changes will take effect real time if it's a .bmp file and not for .jpg images. Second option is to convert JPG to 24-bit BMP files (to look exactly the same, but will triple the file size), but i'm hoping a better way .. i've already googled things but no avail.. i hope you (the helpful reader) can post any .bat or even vbs script to change Desktop Wallpaper instantly with JPG pictures .. hoping there's an answer without installing other apps or scripts ..

• Looking for a powershell script that can pull a file from a set of PC's and FTP

  - by DangeRuss

  I'm looking to write a script (preferably powershell) that will essentially copy a file from a bunch of PC's and FTP it to a server. So the structure of the environment is that we have a file on multiple PC's (around 50 or so) that need to placed on a server. Sometimes one of the PC's may be turned off so the script would first need to ensure the PC is up and running (maybe a ping result), then it would need to go into a directory on that PC, pull a file off of it, rename the file, place into a source directory, then remove the file. Naming convention doesn't matter, but date/time stamp would be easiest. Ideally, it would be best to first move all the files to a source directory to save on FTP bandwidth, but since the files will be named the same, the files must be renamed during the move process. Move not copy because the directory needs to be empty so the file can be re-created the next day. So once moved to the source directory, now all the files need to be FTP'd to a server for processing. After all of this, we need to know which PC's on the list did not respond so we can manually retrieve the file so the script should output a file (txt is fine) that will show which PC's were offline. Everything is one domain and script will be run from an server with admin creds. Thank you!

• Join Domain from VM

  - by Adis

  I have two VMs running on VMWare Player. I use NAT adapter settings. The host machine for VMs is running on corporate network. First VM has Domain controller running and I can log in on that machine using domain credentials. I named domain wm.local When I run IP config on this machine: IP: 192.168.87.132 Def Gataway: 192.168.87.2 DNS server: 192.168.87.2 DHCP server: 192.168.87.254 Second VM cannot join domain. When I try it with domain WM I'm propmted for credentials. And I enter Administrator credentials and than it waits for some time and I get response: "The specified domain either does not exist or could not be contacted" If i type wm.local as domain when trying to join it does not prompt me to login but just shows "An Active Directory Domain Controller (AD DC) for the domain wm.local could not be contacted. And here it takes no time to get this error message. Ipconfig on this machine: IP: 192.168.87.134 Def Gataway: 192.168.87.2 DNS server: 192.168.87.2 DHCP server: 192.168.87.254 I can ping second VM from first one. And I disabled firewalls on both machines. Any ideas? Is there any manual for this?

• Same script, different behavior [migrated]

  - by Antoine_935

  I just stumbled upon an interesting bug... Still trying to figure out what is exactly happening. Maybe you can help. First, the context. I'm currently building yet another man to html converter (for some reasons I won't motivate here, but I need it). So, have a look at the screenshot below (see the link), more precisely at the outlined spots. See? On the upper shell, I have &lt ; and &gt ;, that is, escaped html. While on the shell below I have < and directly. But as you can see (or do I seriously need looking glass ?), the command man 2 semget | webmanneris the same on both sides, as is the which webmanner. The two are executed roughly at the same moment, with no modification made to the script between. [Oops, cannot post pictures just yet... Here comes the link] http://aspyct.org/media/webmanner-bug.png But the shell below is older (open about 1 hour ago). Newer shells all print out &lt ;. So my first guess was that it somehow had a cached reference to the old inode of the file, or old blocks or whatever. So I modified parts of the script, at the start and then at the end, to print different messages. And, surprise, the message shown up on both terminals. But still, same difference between &lt ; and <. I'm confused... How to explain that behavior? I'm working on a OSX 10.8 (Mountain Lion) EDIT: OK, there is one big difference: the shell below uses ruby 1.9.3, while above is 1.8.7. Is there any known difference in string handling between the two versions ?

• Dual Monitor + Virtual Desktop software (plus for cube)

  - by xenithorb

  I've recently purchased another monitor, my first one being a TV and being much larger. I now sit at a desk and use my shiny new 24" LED more often, but I like to extend the desktop into the TV. The problem presented with this is to save power and the longevity of my 47" VIZIO, I try to keep it off when possible. What I'm seeking sounds very simple - If any of you have ever used Compiz or Deskspace (Yod'm) - You'll know what im referring to when I talk about a "cube." The most important functionality I'm looking for is the ability to scroll desktop contents between both displays and virtual desktops. Deskspace does and excellent job of presenting an attractive cube, but it creates a separate cube and virtual desktop space for the second extended monitor (now the TV) - Again, what I'm looking to do is scroll between virtual desktops, by passing through both monitors. The net effect of this functionality would allow me to scroll the contents of the extended monitor to the first monitor should a window get caught there without having to turn on the TV. So imagine the horizontal portion of a cube as being actual real monitors - is there anything that allows one to rotate desktops between displays?

• Linksys SFE2000 Interface

  - by boburob

  I have a real problem with a layer 3 Linksys switch. First, every time it looses power, it seems to reset back to an older config. Not only this, but when this happens it looses interface settings on one subnet. This would not be a problem but I am completely unable to get to the interface on the working side. It allows me to log on and then just displays a blank screen. I have tried this on: IE6 IE7 IE8 IE9 Firefox 3.5 Opera Chrome All with the same results, except for Opera, which loads half the interface but nothing I can really use. I really need to get onto this switch so I can sort out routing and VLAN tagged ports, so if anyone has any ideas on either of these issues please let me know ASAP! Thanks! Also, due to its location and my lack of laptops with serial connections I cannot putty into it. UPDATE: Looked into this a bit more and it looks like this model of switch does not save the current config to boot unless you make sure to save it yourself, which explains the first issue, however the broken interface is more worrying!

• Bing Desktop not updating the wallpaper anymore

  - by warmth

  For some reason, first my workstation and then my tablet stopped updating the wallpaper. First I thought it was my company that was avoiding the app to work properly but then I started noticing that the app itself is a mess: It has two storage and formats for the wallpapers: C:\Users\<username>\AppData\Local\Microsoft\BingDesktop\en-US\Apps\Wallpaper_5386c77076d04cf9a8b5d619b4cba48e\VersionIndependent\images with a #####.jpg (single number) image format & C:\Users\<username>\AppData\Local\Microsoft\BingDesktop\themes with a ####-##-##.jpg (date) image format. I read here that deleting the themes folder it will get remade with the new images, and it worked. However those are not the files used by the Wallpaper app and deleting the images folder won't get the same result. I have added Bing Desktop to the Firewall white list and the issue is still there. Any ideas? Currently I'm using DisplayFusion to place the wallpaper manually because the company doesn't allow change the wallpapers (policies). Note: I wrote to the DisplayFusion developers to suggest adding a feature to support Bing Wallpapers. They told me there was no API support to implement it but they will study this possibility (workaround) for the future: http://stackoverflow.com/questions/10639914/is-there-a-way-to-get-bings-photo-of-the-day

• Make nginx config like apache2 virtualhosts

  - by user2104070

  I have web server with apache2 with many subdomains on it like, domain.com, abc.domain.com, def.domain.com etc. etc. Now I got a new nginx server and want to set it up like apache2, so to test I created configs (2 files in /etc/nginx/sites-available/ and link to them from sites-enabled/) as shown, domain.config: server { listen 80 default_server; listen [::]:80 default_server ipv6only=on; root /srv/www/; index index.html index.htm; # Make site accessible from http://localhost/ server_name domain.com; location / { # First attempt to serve request as file, then # as directory, then fall back to displaying a 404. try_files $uri $uri/ =404; } } abc-domain config: server { listen 80; listen [::]:80; root /srv/www/tmp1/; index index.html index.htm; # Make site accessible from http://localhost/ server_name abc.domain.com; location / { # First attempt to serve request as file, then # as directory, then fall back to displaying a 404. try_files $uri $uri/ =404; } } but when I access with domain.com I am getting index.html from /var/www/tmp1 only. Is there something I'm doing wrong in the nginx config?

• i7-980X at 70% speed

  - by Buxley

  Hi we bought a nice computer to use to solve optimization problems. Intel i7-980X@3,33 GHz with 12 GB of Team Group 1600 MHz DDR3 RAM. When we use Gurobi the computer uses all 12 cores at maximum in the beginning of the solve. However after a while (about 8 hrs) it all cores jump between 65 and 85% When I solve the same models on an i7 930 all cores are at a near 100% level even after longer solution times. We first thought that the Hard disk was the bottleneck since Gurobi writes out nodefiles after the memorylimit is used. However since the new computer have 12 GB of RAM we put the memorylimit to 7 GB so the solver only used the RAM and still with the same performance in the processor. Any ideas about the bottleneck? As I said earlier it works at 100% for the first hours or so . Thanks very much for any answers! Our plan was to overclock it but we can't even get it to work at normal speed yet!

• Can't get 1440x900 resolution with GRUB2 although vbeinfo says it's available

  - by TomSW

  I'm trying to use GRUB2 in graphical mode with 1440x900 resolution, but the result is always garbled nonsense: the highest resolution I can get is 1280x800. Word is from googling that long as vbeinfo lists a resolution, GRUB2 can use it. This doesn't seem to be true: vbeinfo says that 1440x900 is available but it doesn't work. Testing it from the GRUB2 command line: set gxfmode=1440x900 terminal_output gfxterm # -> garbled nonsense # back to trusty 640x480 terminal_output console The graphics card is an Intel GM965. Once linux boots the framebuffer switches to 1440x900. Added after epheminent's reply and various experiments vbeinfo lists two sets of modes. The first set runs from 0x160 to 0x16b, with resolutions 768x480, 960x600, 1280x800 and 1440x900 Then - after a bunch of text-only modes - the second set, containing resolutions 1024x768, 800x600, and 640x480 The first set of modes aren't altered by 915resolution. They all work except 1440x900. The resolution of modes in the second set can be altered using the 915resolution module / command available in GRUB2 = 1.99. # in /boot/grub/grub.cfg insmod 915resolution # 30, 32, 34 all work for me: all that varies is which modes are altered 915resolution 30 1440 900 # setting an impossible resolution changes the mode to "text-only" # in my case 1280x1024 is not supported 915resolution 30 1280 1024 Clearly, 1440x900 should just work: adding it with 915resolution is just a workaround.
