• HTTP Caching Server that supports POST

  - by Jeroen

  I am hosting a REST service which is sending appropriate cache-control headers. I use Varnish as a caching server in front of my webserver. However, a limitation of varnish is that it doesn't support caching HTTP POST and HTTP PUT. Is there any alternate caching server that will be able to cache these requests? I understand that caching POST is a bit tricky because you cannot just cache based on the url as a key like for GET; it needs to actually inspect the request body. In case of multipart/form-data requests, there should probably be a limit on the size of the request body for it to be cached (so that big file uploads, etc won't be cached). Nevertheless I really want to be able to cache short HTTP POST, or at least the application/x-www-form-urlencoded ones.

• How does Windows handle Time? Updating RTC, etc. (Active Directory and Novell E-Directory)

  - by bshacklett

  I'm troubleshooting some time issues in my domain and before making any big changes I want to have a thorough understanding of what's going on. I've got a few lingering questions at the moment: What sources (rtc, ntp, etc.) are queried by Windows to keep time? How does this differ in a mixed Active Directory / Novell environment? What is the order that each source is queried in? How does Windows decide whether to act as an NTP client, peer or server? In what situations will Windows update the RTC, if ever?

• Is SmoothWall a good firewall alternative?

  - by Oden

  I found this linux distribution, called SmoothWall. I read its documentation and it looks pretty for me. The only problem is, that I'm not a big linux professional and I have also not a lot of experience but I want to know your thoughts about this "Firewall OS"! Can it be used for small-business environment, with 15-17 PC-s? I would use the server also as cache proxy. Is this a good idea? (I mean, using one server for two things)

• How to delete system default printer forms?

  - by matt wilkie

  On Windows there are system default printer forms which can't be deleted from the Print Server Properties dialog. Is there some other way they can be removed? We are never going to use page sizes like Envelope, B5(JIS), US Std Fanfold, etc. and I'd like to save users (and myself!) from having to scroll through a big long list of noise. Our print servers are Windows Server 2003 if that makes any difference. thanks.

• What happens if an OpenStack cloud controller dies?

  - by magu

  I've been reading up on OpenStack and how we can re-create an EC2/S3-style cloud for our internal development and I'm having a hard time finding information on how the OpenStack cloud controller provides redundancy of the cloud management services. I know I can setup multiple Swift and Nova nodes, but not a single document/article/howto/wiki contains information on: a) what happens if the cloud controller node dies; and b) how to setup redundant cloud controllers. It seems to me that, although it is massively scalable, there is a big single-point-of-failure built into OpenStack. Can anyone with more experience on OpenStack please shed some light as to how it all works in regards to high-availability?

• Which CMS for a mobile app? No HTML, just XML or JSON

  - by Sascha

  I am a newbie in content management systems. I would need a CMS that can transfer content by XML or JSON to a client. It is ok if the CMS can also manage HTML websites, but the priority is on the data transfer over a web service. Which is the best CMS to use here? I want to avoid spending endless hours learning all the big CMS systems just to find out that they don't support this feature or that it's badly integrated. Thanks.

• Files slow to save sometimes after Ubuntu upgrade

  - by Matchu

  I haven't quite been able to track down why this happens sometimes in Ubuntu 10.04 and not other times. I'll go into gedit or OpenOffice.org and try to save files, and, during some sessions, it will take up to 10 seconds to save the file, sometimes causing the program to become unresponsive. But during these same sessions, the files sometimes save instantly. This didn't start happening until after the 10.04 (Lucid) upgrade. I suspect that something is reading all the changes I make, or that there's some other big file action going on, or something like that. I disabled Tracker a while back, before the upgrade, and don't see it under the settings - could it be back under a different name under Lucid? You probably don't already know the answer, but how can I go about finding the cause of this problem?

• A desktop Wiki editor/viewer: is there anything out there?

  - by MrBertie

  I'm a big user of wikis, mainly Dokuwiki, I really like the clarity and ease of use of simple text files. However all good wikis seem to require a web-server of some kind; has anyone come across a good desktop wiki editor/viewer that work with plain-text files, and allow me to work with wiki text files just like any other document file type (note: not a desktop wiki running inside a local webserver) Before you rush to suggest (I hope!) I have done months of research on this and have tried Wixi, Wikidpad, zulupad.... Any ideas anyone?

• How do I securely share / allow access to a drive?

  - by sleske

  To simplify backing up a laptop (Windows Vista), I'm planning on sharing its C: drive (with password protection) and using that to back it up from another computer. What are the security implications of this? If I share C: with a reasonable password, how big is the risk of compromise if the system is e.g. inadvertently used on a public WLAN or similar? Background: I'm planning to use [Areca Backup][1] to back up two systems (Windows XP and Vista). My current plan is to install Areca on the XP box, and share the Vista system's C: as a shared folder, so the XP system can read it. Then I can set up the drive as a network drive and have Areca read it like a local drive. Of course, if you can think of a more elegant way of doing this, I'm open to suggestions.

• Copying files from Public folder to C: takes a minute, even though they are same hard drive and same

  - by Jian Lin

  I have a big file, like 2GB, and would like to copy it from Network -> Bookroom -> Users -> Public (this is the computer in the bookroom in the house) to c:\myfiles and they are actually on the SAME hard drive (and same partition). But copying still takes a minute or so? I thought if on the same hard drive and partition, then it is a "move" and it should take 2, 3 seconds only. that public folder also is \\Bookroom\Users\Public

• Offline installer for .net 3.5 sp1 not working

  - by Tim Tom

When will the microsoft learn? Now this is a loop. When I try to install from Server Manager, I get installation cannot be done. It needs installation disk. Does that mean I can't install at all without the installation disk in presence?

• `rsync` NEVER uses its 'famous' delta-transfer!

  - by o_O Tync

  I have a big iso image which is currently being downloaded by a torrent client with space-reservation turned on: that means, file size is not changing while some chunks in in (4 Mib) are constantly changing because of a download. At 90% download I do the initial rsync to save time later: $ rsync -Ph DVD.iso /some/target/ sending incremental file list DVD.iso 2.60G 100% 40.23MB/s 0:01:01 (xfer#1, to-check=0/1) sent 2.60G bytes received 73 bytes 34.59M bytes/sec total size is 2.60G speedup is 1.00 Then, when the file's fully downloaded, I rsync again: total size is 2.60G speedup is 1.00 Speedup=1 says delta-transfer was not used, although 90% of the file has not changed. Why?!

• hardware: delay and distinct 'click' before hard drive access

  - by matt lohkamp

  I have a windows 7 box stashed away in my closet, containing (among other things) 2 big HDDs linked together as a mirrored volume - basically a super lazy NAS / media server. I've noticed that when that drive is accessed (whether locally, on the machine itself, or remotely, from another computer, or my xbox, for example) there's a noticeable pause, and then from the computer itself, a 'click!' noise, after which the drive is accessed; e.g. open \\computername\shared\, wait 2 seconds, hear 'click!' and then see files appear in windows explorer. Any ideas? Otherwise the drive preforms normally - is it a windows thing? a HDD-about-to-die thing? Or a "yeah that always happens, you've just never noticed it before" thing?

• What is a good php 5.3.x shared hosting company?

  - by Abba Bryant

  I am looking for the best shared host - features-wise, not price - for hosting CakePHP and Lithium applications. I would like to be able to use MongoDB / MySQL as well as have access to some of the more common PHP extensions like MCrypt, etc. I currently use dreamhost with a custom PHP 5.3.x build on my sandbox domain - Please do not suggest this as a solution. I want to move away from managing my own PHP build if possible. I need ssh access but email support isn't as big of an issue.

• Why is access to my database very slow?

  - by Fabien

  I have a mysql database that used to work perfectly fine, but now it is dead slow on startup. When I type in $> mysql -u foo bar I get the following usual message for about 30 seconds before I get a prompt : Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Of course, I tried it and it goes a lot faster : $> mysql -u foo bar -A But why do I have to wait so long in regular startup ? This is not a very big database, and data does not seem to be corrupted (everything looks fine after startup). I have no other client connecting to the mysql server at the same time (only one process is shown with the command show full processlist) and I have already restarted the mysqld service. What's going on ?

• How do I start silverlight on netflix in full screen automatically?

  - by KronoS

  I know that there this great big button that I can click for full screen on the bottom left of the screen. What I'm doing though is launching the direct movie/tv episode in chrome from XBMC using XBMCflicks. It's like pasting the video html address in the address bar and going directly to the video feed. Here's my dilemma, I want a fully working, no need for a keyboard/mouse HTPC, which means I don't want to have to click on the 'full screen' button. Is there a way to run chrome and silverlight automatically in full screen mode when launched?

• Best method(s) to backup VMs running on HyperV?

  - by Kara Marfia

  We're in the middle of P2V'ing most of the network, so the current backup method is likely the worst - the backup agent is still installed on the guest OSs, and the backup device is dutifully pulling them onto tape, one file at a time. I suspect there's a clever way to script (PowerShell?) a suspend on the VMs, then backup of the .vhd files, and unsuspend the VMs. This seems like it would provide big speed benefits, while losing file-level restore (might be best for things like DCs and app servers). What methods/policies have you hammered out?

• Where to download MS SQL Server 2005 Developer Edition?

  - by Mark

  Just got put in charge of a big web project. All I know is the web server is running MS SQL 2005, so I need something comparable to test locally. I figure developer edition is my best bet because it offers everything that the enterprise edition does, but is for development purposes only. But this page is pretty worthless http://www.microsoft.com/sqlserver/2005/en/us/developer.aspx Where do I actually download it? What about SQL 2005 Express? Would that meet my needs? I can't figure out all the differences between these stupid MS products.

• What's the easiest way to create an HTTP proxy which adds basic authentication to requests?

  - by joshdoe

  I am trying to use a service provided by a server which requires basic HTTP authentication, however the application I am using does not support authentication. What I'd like to do is create a proxy that will enable my auth-less application to connect via the proxy (which will add the authentication information) to the server requiring authentication. I'm sure this can be done, however I'm overwhelmed with the number of proxies out there and couldn't find an answer how to do this. Basically it seems all I want to do is have a proxy serve this URL: http://username:password@remoteserver/path as this URL: http://proxyserver/path I can run it on Linux, but a plus if I can run it Windows as well. Open source or at least free is a must. A big plus is if it's fairly straightforward to setup.

• Request Multiple Maya Floating Server Licenses for extra Satellite clients

  - by Rob

  Hello all: I am currently setting up a 'render farm' for Maya 2008 Unlimited. One Maya workstation license comes with the ability to render on eight satellite nodes. It works perfect, the remote rendering works like a charm. However, we have additional boxes to set up as satellite rendering nodes, and we have extra Maya workstation licenses. Ideally, the workstation can take two licenses and thus render on 16 nodes, but I haven't been able to figure it out, or determine if it is actually possible. It's a big project, where rendering the entire thing is in the scope of weeks, so the speed up would be worth it. Any thoughts?

• VLC subtitle size

  - by Kayhano

  My problem is with VLC subtitle sizes. With different movie resolutions subtitle font size is same and when i make the movie fullscreen subtitles became too small or too big depending on the res. For example a movie with 360p res i use 25px for font size and then if i watch another movie with 1080p this 25px becomes too small to read. Then i had to adjust font size for each movie. Is there a setting to automatically resize the font or set a single font size for fullscreen?
