• Can't move or access WSS Central Administration site

  - by Jim

  We have several WSS Servers: WSS1 WSS2 WSS3 WSS4 SharePoint thinks that Central Administration is on WSS3 and that it can be access via SSL on port 22641. The problem is that central administration is not there. It was removed using the config wizard. We removed central admin from all servers to clean everything out, and we tried installing Central Admin on WSS1. The alternate access mappings still point to central admin on WSS3. We tried deleting the alternate access mappings, but SharePoint won't let you delete central admin's mapping. Later, we removed central admin from all of our servers and tried creating the Central Admin website on WSS3, where SharePoint already thinks it is. But for some reason SharePoint is creating the alternate access mappings using SSL, and we don't have a certificate for the server. Why is SharePoint creating alternate access mappings routing an https internal URL by default? How can we move central administration to a new server? We are using WSS 3.0.

• How can I send a GET request containing a colon, to an ASP.NET MVC2 controller?

  - by Cheeso

  This works fine: GET /mvc/Movies/TitleIncludes/Lara%20Croft When I submit a request that contains a colon, like this: GET /mvc/Movies/TitleIncludes/Lara%20Croft:%20Tomb ...it generates a 400 error. The error says ASP.NET detected invalid characters in the URL. If I try url-escaping, the request looks like this: GET /mvc/Movies/TitleIncludes/Lara%20Croft%3A%20Tomb ...and this also gives me a 400 error. If I replace the colon with a | : GET /mvc/Movies/TitleIncludes/Lara%20Croft|%20Tomb ..that was also rejeted as illegal, this time with a 500 error. The message: Illegal characters in path. URL-escaping that | results in the same error. I really, really don't want to use a querystring parameter. related: Sending URLs/paths to ASP.NET MVC controller actions

• The cleaner way to upgrading a Mac

  - by AngryHacker

  This page list a way to do a clean install of Snow Leopard without loosing any of your settings. This sounds pretty darn good since my mac did get a bit slower over time. The method basically involves copying your existing drive to an external one, then doing an Erase and Install from the installation DVD. After the installation, supposedly, I'll be presented with an option to migrate settings from another Mac. I am not all that familiar with the Mac, hence what is probably a simple question. With this migration option, will I be able to copy over all my applications or will I have to reinstall them from scratch?

• Why won't the floppy mount?

  - by dboarman-FissureStudios

  The 1.44Meg floppy won't mount in my Nautilus file browser. When I try to mount it, it says there is no media in the drive. Yet, I can write to the floppy through the terminal using the 'cp' command. I can enter the command: mount -t ext2 /floppy and it mounts. I have also run a check and the disk itself is 100% clean. So, why can't I get the nautilus browser to open up the floppy? Is there a way to see the actual floppy from the terminal?

• Many RewriteBase in one .htaccess file?

  - by Martti Laine

  Hello I have a domain and a wordpress-blog on same server. Now I have a problem (surprise). The wordpress is located on /httpdocs/blog/ and domain is pointing to /httpdocs/ and I'm trying to redirect it to /httpdocs/domain/. But, obvisiously, I have permalinks in Wordpress. Here's my current .htaccess: RewriteEngine On RewriteBase /blog/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /blog/index.php [L] RewriteBase / RewriteCond %{HTTP_HOST} domain.com RewriteCond %{REQUEST_URI} !^/domain RewriteCond %{REQUEST_URI} !^/cgi-bin RewriteRule ^(.*)$ domain/$1 [L] But as you already propably assumed, this doesn't work. Wordpress' permalinks affects to /domain/ also, so my images and other urls go wrong. Any advice? Is it possible to use RewriteBase like this? Martti Laine

• Persisting right click menu highlight

  - by Charlie Somerville

  I used to have this problem sometimes in Vista, but now I'm using Windows 7 (it was a clean install, reformatted hard drive) I'm disappointed that it's happening again. Basically what happens is sometimes when I right click on something and click an entry in the context menu, the highlight from entry remains on the screen, in front of everything else. I can get rid of it by changing my theme to Aero Basic and back again, but it's not a nice solution as it takes too long and often once I get rid of it, it comes back. Here you can see an example of what's happening - the highlight is there from Chrome's context menu. Does anyone know how to fix this?

• Client/server application RPC connection gets disconnected very frequently

  - by Chris Thompson

  I have a client/server application that uses RPC for the client to communicate with the server. Fairly regularly, I get an event in the Application log that the RPC connection was disconnected: Client callback failed ((0x80010108) ) I have the Windows Firewall disabled on both machines. I've even run the client on a second computer with a clean Windows XP install without any group policies. This has been going on for a long time and no one has been able to figure out why it's happening. The same client/server app works fine at other client locations. Any thoughts?

• Use mod_rewrite to redirect from example.com/dir to www.example.com/dir

  - by kavoir.com

  Assume / is the document root of my domain example.com. /.htaccess RewriteEngine on RewriteCond %{HTTP_HOST} ^golfcoursesd\.com$ [NC] RewriteRule ^(.*)$ http://www.golfcoursesd.com/$1 [R=301,L] /dir/.htaccess <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /dir/index.php [L] </IfModule> I know how to redirect example.com/dir to www.example.com/dir, because /.htaccess does the very job. However, the trick here is that I have to keep /dir/.htaccess to serve up virtual directories (such as /dir/state/AK/35827/ which aren't actual directories) if you know what I mean. Problem is, if I keep /dir/.htaccess, a request of: http://example.com/dir/state/AK/35827/ DOES NOT redirect to: http://www.example.com/dir/state/AK/35827/ as would: http://example.com/ redirect to: http://www.example.com/ Not sure if I made it clear. Basically, how to make http://example.com/dir/state/AK/35827/ correctly redirect to http://www.example.com/dir/state/AK/35827/ AND I can serve virtual URLs?

• Recover from a corrupted couchbase install

  - by jcolebrand

  We have a couchbase installation on a Windows 2008 R2 server that got corrupted (this was from before my tenure, now I want to clean it up). There is no add-remove entry in the Programs and Features list. There is no active service in services.msc. However, something still thinks Couchbase is installed. Shy of wiping the box (we aren't quite to "redeploy test environment servers at the push of a button" altho I'm working on it), how can I ensure that all remnants of couchbase installs prior are now gone? I believe the previous install was in the Couchbase 2.x range, but it may have been 1.7+ Running the installer again gives "Installer needs to update registry value in order to upgrade from the previous version. Please run installer again to continue."

• Skip sanitization for videos in html5lib

  - by pug

  I am using a wmd-editor in django, much like this one in which I am typing. I would like to allow the users to embed videos in it. For that I am using the Markdown video extension here. The problem is that I am also sanitizing user input using html5lib sanitization and it doesn't allow object tags which are required to embed the videos. One solution could be to check the input for urls of well-known video sites and skip the sanitization in those cases. Is there a better solution?

• Something eating space on OS drive

  - by noquery

  I am facing low disk space issue from last few days. I checked with Restore,System Volume Information, $Recycled folders. But there is nothing which is occupying space. I had scanned my system for virus too. Total size of C: is 18 GB. But when I select all folders inside C: and query for used space, it shows 20+ gb space is used. I vacate space some how by deleting temp files, program's cache files, disk clean up etc up to (3 gb). And I ensured that no cache/temp files are recreated who can use the space again. Even after cleaning so much data, I am again facing low disk space issue. Something is eating disk space within 15-20 mins.

• Windows Upgrade vs Full Install

  - by James Atkinson

  I'm in the process of purchasing a Netbook for use while traveling. The included OS is XP, however, I would like to upgrade(?) to Windows 7. My question: Does a Windows Upgrade have the same physical footprint and performance as a full install? Does an upgrade leave behind non used files/resources that were originally included in XP? If so, are there ways to reduce this? I'm trying to reduce as much OS bloat as possible. Please let me know if my question is unclear. Thanks. Related to http://superuser.com/questions/60646/is-a-clean-install-really-better-than-an-upgrade however, this doesn't address the "leftovers" question.

• Django - categories & sub-categories

  - by Bluey

  Some advice needed on how I can structure my models for my site. I have seen this post from Django project but still a little lost. Also come across Django-MPTT - but that's no help and possibly overkill. I'm looking to have categories & subcategories that are shown in the URLs like this: mysite.com/Level1/Maths/Calculations/Addition/ mysite.com/Level3/English/ mysite.com/Level2/English/Storytelling/ In my admin interface I'm looking to have drop downs for each level of category or subcategory. Also at each level I will be querying items (another model) like get all items that have the category 'Level1' AND 'Maths'. There could also be a situation where I have five or more subcategories. How is it best to create my models for best performance? It it worth using tagging instead?

• Django/MySQL - __istartswith not producing case-insensitive query.

  - by TheLizardKing

  I make use of generic views and I am attempting to query my MySQL db (utf8_bin collation) in a case insensitive manor to try to find all my song titles that start with a particular letter. view.py def tracks_by_title(request, starts_with): return object_list( request, queryset = Track.objects.filter(title__istartswith=starts_with), template_name = 'tlkmusic_base/titles_list.html', template_object_name = 'tracks', paginate_by = 25, ) and my urls.py urlpatterns = patterns('tlkmusic.apps.tlkmusic_base.views', (r'^titles/(?P<starts_with>\w)/$', tracks_by_title), ) the query it produces according to the django debug toolbar is: SELECT `tracks`.`id`, `tracks`.`url`, `tracks`.`artist`, `tracks`.`album`, `tracks`.`genre`, `tracks`.`year`, `tracks`.`title`, `tracks`.`comment`, `tracks`.`tracknumber`, `tracks`.`discnumber`, `tracks`.`bitrate`, `tracks`.`length`, `tracks`.`samplerate`, `tracks`.`filesize`, `tracks`.`createdate`, `tracks`.`modifydate` FROM `tracks` WHERE `tracks`.`title` LIKE a% LIMIT 1 specifically this line: WHERE `tracks`.`title` LIKE a% LIMIT 1 Why is it not ILIKE which is what I was expecting by using __istartswith? I am using Django 1.1.1 on Ubuntu.

• vista winsxs folder eats disk space

  - by Simpzon

  My machine has been running Vista Ultimate 64-Bit for about two years now. ServicePacks SP1 and SP2 are installed, too. The system partition has a size of 55 GB, which should be quite comfortable under normal circumstances, but about 40GB (no typo) are used by the Windows-Folder, especially the subfolder winsxs, which takes about 35 GB. I have already uninstalled as many programs as possible and did run compcln.exe, to reduce it, but this only gained 2-3 GB. What can I do to clean up without risking system stability? I'm a software developer and this is my daily work environment, which means - I can't risk to get strange side-effects from blindly deleting stuff. - You can maybe deduce some typical usage patterns from this information. Any suggestions?

• rsync to windows (cygwin)

  - by abergmeier

  We have a windows file storage (don't ask) and now I want to rsync with the machine from Windows, Mac and Linux. So I installed freeSSHd (login shell is set to C:/cygwin64/bin/sh.exe), set up certificates and testing from Linux the test.dat has 0 bytes: ssh myuser@winmachinename "C:/cygwin64/bin/true.exe" > test.dat Even double checking with actual output works fine: ssh myuser@winmachinename "C:/cygwin64/bin/ls.exe" > test.dat Now, when I call rsync: rsync --progress -avz -e ssh myuser@winmachinename:/c/Users ~/test it fails with: protocol version mismatch -- is your shell clean? (see the rsync man page for an explanation) rsync error: protocol incompatibility (code 2) at compat.c(174) [Receiver=3.1.0] As far as reading the docs, this should not happen, when the first test is successful!? I am by now out of ideas - any recommendations how to debug this? EDIT: | OS | rsync version | |:--------------|:------------------------------------------| | Windows | rsync version 3.0.9 protocol version 30 | | Linux | rsync version 3.1.0 protocol version 31 |

• Why does iTunes make 2 copies of my music when adding to library?

  - by NoCatharsis

  I set iTunes to "Keep iTunes Media folder organized" and to "Copy files to iTunes Media folder when adding to library" because I prefer to keep my music consolidated, organized, and consistent. However, when I have MP3s that are external to iTunes, then try to add via File Add Folder to Libary, iTunes creates 2 copies of the file in the iTunes folder - one with the original song name and another with the original song name followed by the number 1. Here is what I thought would happen, and I hope is possible: 1) Click File Add Folder to Library 2) Select folder external to iTunes 3) Click OK 4) iTunes creates a clean new folder in the iTunes Music directory with exactly 1 of each file 5) Only 1 of each song is shown within iTunes Is this too much to ask? I am not an iTunes fan at all after 2 years dealing with the poor programming of this application. I hope someone can help me find the faith...

• Is there a standard site structure format?

  - by artlung

  Is there a standard site structure format? The use of this would be for export and import into a CMS or framework to define the urls, content, metadata for a website. Something tool agnostic would be the goal. JSON, YAML, XML, whatever. Maybe something like: { 'baseurl': 'http://example.com', 'site': [ {'slug': '/', 'title': 'ExampleCo. Inc.'}, {'slug': '/about', 'title': 'About Our Company'}, {'slug': '/services', 'title': 'Our Services'}, {'slug': '/products', 'title': 'Products'}, {'slug': '/products/purchase', 'title': 'Purchase Products Now'}, {'slug': '/products/downloads', 'title': 'Downloads'}, {'slug': '/contact', 'title': 'Contact Us'} ] } My thinking is that it would allow you to quickly populate a content management system or framework with a generic site navigational structure. Does something like this exist?

• Is there an offline version of Smush.it available?

  - by Jonathon Watney

  Sometimes I use Smush.it via the YSlow Firefox plugin to non-destructively reduce the file size of JPG images. Is there an offline version available that runs on Windows? And if not is there an alternative? The reason I'd like an offline version is that I'd like to optimize images before I deploy them. Currently Smush.it accepts only public facing URLs for images or a web page (via YSlow) and can't access my internal network. That means I have to deploy, optimize, replace images and deploy again. I'd really like to deploy the optimized images on the first deploy. Update: Here's a very similar question.

• MODI leaking memory

  - by Khragg

  I have an app where I'm using MODI 2007 to OCR several multi-page tiff files. I have found that when I kick it off on a directory that contains several good tiffs but also some tiffs that cannot be opened in Windows Picture and Fax Viewer, then MODI also fails to OCR those "bad" tiffs. When this happens, the app is unable to reclaim any of the memory that was used by MODI to OCR those tiffs. After the tool tries to OCR too many of these "bad" tiffs, the machine runs out of memory and the app crashes. I have tried several code fixes from the web that supposedly fix any MODI memory leaks, but so far none have worked for me. I am pasting in the part of the code below that does the OCRing: StringBuilder strRecText = new StringBuilder(10000); MODI.Document doc1 = new MODI.Document(); doc1.Create(name); try { doc1.OCR(MODI.MiLANGUAGES.miLANG_ENGLISH, true, true); // this will ocr all pages of a multi-page tiff file } catch (Exception e) { doc1.Close(false); // clean up if (doc1 != null) { GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers(); System.Runtime.InteropServices.Marshal.FinalReleaseComObject(doc1); doc1 = null; } } MODI.Images images = doc1.Images; for (int imageCounter = 0; imageCounter < images.Count; imageCounter++) { if (imageCounter > 0) { if (!noPageBreakFlag) { strRecText.Append((char)pageBreakChar); } } MODI.Image image = (MODI.Image)images[imageCounter]; MODI.Layout layout = image.Layout; strRecText.Append(layout.Text); GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers(); if (layout != null) { System.Runtime.InteropServices.Marshal.FinalReleaseComObject(layout); layout = null; } if (image != null) { System.Runtime.InteropServices.Marshal.FinalReleaseComObject(image); image = null; } } File.AppendAllText(ocrFile, strRecText.ToString()); // write the OCR file out to disk GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers(); if (images != null) { System.Runtime.InteropServices.Marshal.FinalReleaseComObject(images); images = null; } GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers(); doc1.Close(false); // clean up if (doc1 != null) { System.Runtime.InteropServices.Marshal.FinalReleaseComObject(doc1); doc1 = null; } GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers();

• Recover RAID 5 data after created new array instead of re-using

  - by Brigadieren

  Folks please help - I am a newb with a major headache at hand (perfect storm situation). I have a 3 1tb hdd on my ubuntu 11.04 configured as software raid 5. The data had been copied weekly onto another separate off the computer hard drive until that completely failed and was thrown away. A few days back we had a power outage and after rebooting my box wouldn't mount the raid. In my infinite wisdom I entered mdadm --create -f... command instead of mdadm --assemble and didn't notice the travesty that I had done until after. It started the array degraded and proceeded with building and syncing it which took ~10 hours. After I was back I saw that that the array is successfully up and running but the raid is not I mean the individual drives are partitioned (partition type f8 ) but the md0 device is not. Realizing in horror what I have done I am trying to find some solutions. I just pray that --create didn't overwrite entire content of the hard driver. Could someone PLEASE help me out with this - the data that's on the drive is very important and unique ~10 years of photos, docs, etc. Is it possible that by specifying the participating hard drives in wrong order can make mdadm overwrite them? when I do mdadm --examine --scan I get something like ARRAY /dev/md/0 metadata=1.2 UUID=f1b4084a:720b5712:6d03b9e9:43afe51b name=<hostname>:0 Interestingly enough name used to be 'raid' and not the host hame with :0 appended.

If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 Per Shanes' suggestion I tried root@tanserv:/home/mushegh# mkfs.ext4 -n /dev/md0 mke2fs 1.41.14 (22-Dec-2010) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=128 blocks, Stripe width=256 blocks 122101760 inodes, 488379392 blocks 24418969 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=0 14905 block groups 32768 blocks per group, 32768 fragments per group 8192 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968, 102400000, 214990848 and run fsck.ext4 with every backup block but all returned the following: root@tanserv:/home/mushegh# fsck.ext4 -b 214990848 /dev/md0 e2fsck 1.41.14 (22-Dec-2010) fsck.ext4: Invalid argument while trying to open /dev/md0 The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device> Any suggestions? Regards!

• Windows 8.1 fresh install with Windows 8 licence

  - by typ1232

  I purchased Windows 8 online from Microsoft a while ago. Today Windows 8.1 was released as a free update to Windows 8 users over the Windows Store. I was planning to do a fresh install of Windows 8.1 to have a clean system again and UEFI support because I got new hardware since the Windows 8 installation. So my questions are: Where do I get the ISO installation medium for Windows 8.1 64-bit? I tried this microsoft site where I initially got my Windows 8 ISO from, but when entering my Windows 8 key in the Windows 8.1 installer, it says the key is wrong. Even if I get the ISO, will my old key work? I'm concerned because it didn't work in their installer (see previous point) Do they seriously want me to reinstall Windows 8 and after that upgrade to Windows 8.1 through their Store?!

• read url in binary mode in java

  - by Andrew Zawok

  In java I need to read a binary file from a site and write it to a disk file. This example http://java.sun.com/docs/books/tutorial/networking/urls/readingURL.html could read webpages succesfully, but when I try to read a binary file from my localhost server and write it to a disk file the contents change, corrupting the binary file. Using fc I see that 0x90 is changed to 0x3F and other changes. How do I acess the binary files (read url and write to file) without java or anything else changing ANY characters, like doing any newline conversions or character conversions or anything else, simply reading input url and writing it out as a file.
