• Java web app deployment and ControlTier adoption

  - by Ran

  I've been searching for a configuration and deployment manager tool for my java-linux based web service and have been looking mainly at ControlTier (http://controltier.org). We operate at a medium scale (100's of hosts, multi-DC, dozens of services). There seem to be be plenty of lower level system admin tools such as chef, puppet, cfengine, bcfg2 and more and my understanding and the reason I'm calling them "low level" is that they are great for system level administration tasks such as setting up a mount, file permissions, users etc but aren't designed, for example for java deployments, which usually come with a build process and special java semantics. In many cases any tool can be used to do anything but if it was not designed for the task it can get uncomfortable. OTOH control-tier seem to have been designed just for that - java application deployments, at least that's what all the tutorials on their site demonstrate but here's the problem - The wiki at http://controltier.org/wiki/ is pretty good and stuffed with examples and the company behind the open source CT product is very responsive (pushy...) however, I'm yet to have seen any material from 3rd party users on the net. No success stories, no detailed blog posts, no best practices, no cheat sheets, not even hate letters, nothing. This plays badly for DTO solutions, CT's sponsor for two reasons, one is that it makes me suspicious what's the reason for the poor adoption? and second, what do I do if I get stuck and there's no help page on CT's wiki page and the mailing list is too slow to answer. I'm stuck with a "free" product that a consultancy company is pushing. So my question here - I'd be interested in hearing if anyone has had real world experience with CT for java based web app deployments and if he'd thumb up the product? Any other comments that may enlighten me are welcome of course...

• How to deal with the extremely big *.ost files in a Terminal Server environment which is running out of space

  - by Wolfgang Kuehne

  Our Terminal Server is running out of hard disk space, and the major files which occupy most of the space are *.ost files of the Outook, which come form the users which use the Terminal Server all the time through remote desktop. The Outlook is installed on the Terminal Server and various users can use it. What would be a solution in this case. Is there a way to limit the size of the *.ost files? I read in forums that having the Outlook 2010 set up in Cached Exchange Mode isn't the best practice for an environment where the hdd space is a major constraint. First thing that came to my mind is using folder redirection, and place the ost files (together with the AppData forlder) in a network share, but this does not help, because the ost files are saved a part of the AppData folder which can not be redirected. Then I thought if it is possible to limit the size of the ost file? Or limit the time that it keeps emailed cached, say just emails from the last 6 months are sufficient. Another solutions that came to my mind, moving the ost files somewhere else, this required the old ost file to be removed, and creation of a new one. I am not quite sure if the new OST file will still have cached the emails which where available in the old ost, or will it start caching from where the other one left. What do you suggest?

• Puppet Decentralized Setup

  - by paul.tw

  I want to migrate my existing Puppet setup from master/client to a decentralized solution. I know other solutions, such as Ansible are easier to setup for that purpose, but I really want to stay with Puppet. I found "supply_drop"(https://github.com/pitluga/supply_drop) on github, so I followed the instructions and did the following: rvm gemset create testing rvm use 1.9.3@testing gem install supply_drop The output is the following: [m@ms-MacBook-Pro:~ $ irb 1.9.3-p547 :001 require 'supply_drop' NameError: uninitialized constant Capistrano from /Users/m/.rvm/gems/ruby-1.9.3-p547@testing/gems/supply_drop-0.17.0/lib/supply_drop/tasks.rb:1:in `' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/m/.rvm/gems/ruby-1.9.3-p547@testing/gems/supply_drop-0.17.0/lib/supply_drop.rb:10:in `' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:135:in `require' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:135:in `rescue in require' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:144:in `require' from (irb):1 from /Users/m/.rvm/rubies/ruby-1.9.3-p547/bin/irb:12:in `' Since that doesn't work without problems, I was wondering which alternatives are there available to do the same. Do you have any suggestings?

• URL sniffer/downloader

  - by Ricket

  Some websites have Flash content that plays music or videos. Most of the time they don't show you the URL of these music or videos, but for example, you can sniff a YouTube webpage and find the flv file that YouTube is actually requesting and playing. Right now I'm using Orbit Downloader, which has a feature called Grab++ that does just this; you start it, and then you refresh the page, and it shows you all files of certain types (image, audio, video) that the webpage requests, and then you can select one or more and download and it downloads them. But, I don't like Orbit, it installs plugins and has the whole download manager thing which I don't really want. What is a good alternative program? I'm not looking for websites like kickyoutube.com, I want a URL sniffer I guess. HTTPGuideDog used to be my Firefox add-on that did exactly this, but it hasn't been updated even to FF3 (and yes I know I can hack it to load anyway, I'm looking for something natively available preferably). I vaguely know of WireShark but last time I used it, I believe it captures individual packets, which is a little too fine-tuned for me. I just want to be able to see what's happening, and download something that the webpage downloaded. Oh, and I'm using Windows 7. Linux probably has some fancy command-line tool, but it just won't cut it for me. :-\ Edit: Oh, and something free please. Feel free to mention paid solutions though.

• Merge changes in Microsoft Word documents

  - by Álvaro G. Vicario

  I'm using Microsoft Word 2002 to maintain some documentation. The documents are stored in a version control repository (Subversion) together with the source code it documents. My Subversion client (TortoiseSVN) comes with a little VBA script that allows to leverage the built-in revisions feature when merging different branches. In other words, when I want to copy changes from one document to another, Word compares both documents (source and target) and builds a third document that has the contents of the source doc tagged as revisions, so I can then review differences one by one and confirm or discard changes. While this is handy, it also means that making a single change to the source document forces me to review all the differences between both documents and discard all of them except the only actual change. My questions is... Do you know about an application or plug-in that's able to find the differences between two Word documents and apply those differences to a third document? (I know 2002 is very old but that's what my company gives me; I'm open to solutions that use newer versions though.)

• Forwarding HTTP Request with Direct Server Return

  - by Daniel Crabtree

  I have servers spread across several data centers, each storing different files. I want users to be able to access the files on all servers through a single domain and have the individual servers return the files directly to the users. The following shows a simple example: 1) The user's browser requests http://www.example.com/files/file1.zip 2) Request goes to server A, based on the DNS A record for example.com. 3) Server A analyzes the request and works out that /files/file1.zip is stored on server B. 4) Server A forwards the request to server B. 5) Server B returns file1.zip directly to the user without going through server A. Note: steps 4 and 5 must be transparent to the user and cannot involve sending a redirect to the user as that would violate the requirement of a single domain. From my research, what I want to achieve is called "Direct Server Return" and it is a common setup for load balancing. It is also sometimes called a half reverse proxy. For step 4, it sounds like I need to do MAC Address Translation and then pass the request back onto the network and for servers outside the network of server A tunneling will be required. For step 5, I simply need to configure server B, as per the real servers in a load balancing setup. Namely, server B should have server A's IP address on the loopback interface and it should not answer any ARP requests for that IP address. My problem is how to actually achieve step 4? I have found plenty of hardware and software that can do this for simple load balancing at layer 4, but these solutions fall short and cannot handle the kind of custom routing I require. It seems like I will need to roll my own solution. Ideally, I would like to do the routing / forwarding at the web server level, i.e. in PHP or C# / ASP.net. However, I am open to doing it at a lower level such as Apache or IIS, or at an even lower level, i.e. a custom proxy service in front of everything. Thanks.

• Email encoding on IIS7

  - by Ivanhoe123

  All emails sent from the server are displaying Cyrillic letters as weird characters, for example: Можно. Regular alphabet letters are properly rendered. I searched all across the web but was not able to find any solutions. Here is some information about the system: Dedicated server with Windows 2008 and IIS7 Application are in PHP (run as FastCGI) If of any importance, Smartermail is installed on the server The emails are sent using PHPs mail() function through a Drupal website. Encoding on that site is set up properly and there are no display issues on front end. Where is the problem? How can I make Cyrillic letters to be properly encoded? Any help is greatly appreciated. Thanks!

• Why can't I boot in to Windows Recovery Environment to fix my HDD or salvage my data?

  - by Kevin

  I've been trying to get in to WindowsRE to salvage the files on my Sony Vaio laptop after it failed to load Vista (it finally, consistently displays "Error loading operating system" after months of such intermittent failures, usually rectified via restarts or utilizing Startup Repair or CHKDSK from WindowsRE) . The problem is, after successfully accessing it once after this failure (and many times before over the course of the laptop's life), I can no longer get it to load. During the last successful access (right after the failure), I ran startup repair, which itself failed and notified me that the boot sector was corrupt. I attempted to head in to Sony's proprietary recovery tools menu, which is accessible from WindowsRE when it is loaded from the recovery partition or recovery disk, however it hung. I have since been unable to access the recovery environment after restarting, using any of these methods: Access via the recovery partition (pressing F10 on boot) Access via recovery DVD (created using the same computer when it was healthy) Access via a Windows Vista installation DVD All three methods produce the same results: The computer acknowledges the boot attempt The computer successfully gets passed the "Windows is loading files" screen The computer successfully gets passed the Windows loading screen The computer then stalls at a black screen, while showing HDD activity (via indicator light). After a few minutes, the HDD activity ceases, and after a few more minutes, the over sized cursor that is utilized in WindowsRE appears on the black screen. The actual recovery environment, however, never appears, even after leaving the computer in such a state overnight. What is fustrating is that other bootable utilities, such as SeaTools for DOS and MemTest, boot up and run fine. In running perfectly normally, MemTest was able to produce a plethora of errors utilizing my RAM. I'm inclined to believe the RAM's faultiness may causing the WindowsRE booting to fail. Would this be a valid assumption? If I'm not mistaken, booting from external media utilizes the RAM, so such a reason is plausible, assuming my knowledge of bootloading is correct. Other than that, I can't figure out any reason why all the bootable utilities except WindowsRE run fine. Does anyone know what the problem is, or could be? Any solutions?

• Problem with mydomain.com no prefix

  - by user10711

  Short question is. I have a domain name mydomain.com, we have a company website hosted on an IIS server 2003 configuration. Going to the address bar and typing www.mydomain.com will show my website properly. Typing mydomain.com into the same address bar will return an under construction website that seems to be hosted on my webserver. My domain name is hosted by Network Solutions, and I think I have it configured correctly using their advanced DNS services. In their settings I have www.mydomain.com, * and @ also pointed to the ip address of my webserver. On my webserver itself using the IIS manager, under the Web Site, and Web Site Identification. I have configured both www.mydomain.com and mydomain.com configured to work on the IP address on the webserver. I am hosting 4 different websites on my IIS server, all the other sites use prefixes other than www, an example is mail.mydomain.com and a couple of others. None of them show an under construction page as their default homepage. I am really at a loss as to why it would show an under construction page, especially since it seems to be pointing to the correct server. The reason this is such a big deal is because when you search for my company on google, the link there is for mydomain.com and by clicking on the link it shows under construction which is really quite embarrassing. Thanks in advance for any help and if there are further questions let me know.

• How do I disable the firewall on blackberry?

  - by user15660

  I own a Blackberry 9630 tour.(Sprint). The firewall is enabled with a lock sign and grayed out. I'm not able to disable it. Because of this many of my blackberry apps don't work as it gives a message "The application has tried to open a connection that's not allowed by your IT policy". I tried all options and there's nothing to disable. This is a personal blackberry and I don't have an IT policy on it. I did all methods like wiping, formatting/resetting to factory settings acc. to blackberry site by running their reset app from PC etc etc. but nothing works I tried CrackUtil for blackberry and that worked and wiped the blackberry. I restored my bb and started using it just to notice that the firewall is enabled back after a desktop manager connection to PC. I even made sure the policy.bin file on PC is a regular one with no IT policy. How do I get this disabled? I had the same problem on my old blackberry 8330 and crackutil disabled the firewall. but after a few days after a desktop manager update of blackberry OS and other small stuff the firewall got enabled again. Please give me a solutions to disable the firewall on blackberry

• Fully FOSS EMail solution

  - by Ravi

  I am looking at various FOSS options to build a robust EMail solution for a government funded university. Commercial options are to be chosen only in the worst case scenario. Here are the requirements: Approx 1000-1500 users - Postfix or Exim? (Sendmail is out;-)) Mailing lists for different groups/Need web based archive - Mailman? Sympa? Centralised identity store - OpenLDAP? Fedora 389DS? Secure IMAP only - no POP3 required - Courier? Dovecot? Cyrus?? Anti Spam - SpamAssasin? what else? Calendaring - ?? webmail - good to have, not mandatory - needs to be very secure...so squirrelmail is out;-)? Other questions: What mailbox storage format to use? where to store? database/file system? Simple and effective HA options? Is there a web proxy equivalent to squid in the mail server world? software load balancers?CARP? Monitoring and alert? Backup? The govt wants to stimulate the local economy by buying hardware locally from whitebox vendors. Also local consultants and university students will do the integration. We looked at out-of-the-box integrated solutions like Axigen, Zimbra and GMail but each was ruled out in favour of a DIY approach in the hopes of full control over the data and avoiding vendor lockin - which i though was a smart thing to do. I wish more provincial governments in the developing world think of these sort of initiatives As for OS - Debian, FreeBSD would be first preference. Commercial OS's need not apply. CentOS as second tier option...

• Windows 7 taskbar groups to use vertical menus only, not thumbnails?

  - by Justin Grant

  I frequently have 10 or more windows of the same application (e.g. Outlook, Word, IE, etc.) open at one time. Windows 7's new taskbar grouping thumbnail feature shows a preview of open windows (aka thumbnails) when you single-click on the taskbar group for that application. But when I have over 10 windows open (more thumbnails than will fit horizontally on my screen), Windows reverts to a vertical menu. This is disconcerting since I need to train myself to deal with two separate behaviors and can never anticipate what I'm going to see when I click on a taskbar group. Furthermore, I find the thumbnails more difficult to visually scan through (vs. the vertical menu) because only 1-2 words of each window's title are shown. Typically that's not enough text to disambiguate and help me find the right window. I'd like to force Windows 7's taskbar grouping to always show a vertical menu (like in XP) instead of sometimes showing thumbnail previews and sometimes showing a vertical menu. Anyone know how (whether?) this can be done? UPDATE: BTW, I'm running the RTM version (build 7600) of Windows 7. There are apparently other solutions out there which work on earlier builds, but which don't work on the RTM build.

• iPhone Lag Terrible - SLOW - What's going on with the iPhone OS?

  - by Sam Schutte

  I've had my iPhone 3G for about a year now, and it seems like at least once a month, it gets bogged down and gets slower and slower - horrible lag when typing, going back to the home screen or opening an app can take 20 seconds. Has anyone else run into this and found "the" solution. What you always read on other boards is to reboot the handset (hold down home and the power button), but that doesn't improve anything for me. I've reinstalled the OS like 5 times now, and I'm getting pretty sick of doing it so often. And I don't buy that it's a hardware issue really, since it works fine for weeks after a fresh install. Anyone have a solution or an idea of what specific actions cause this kind of evident data corruption (OS corruption?) and slowness? Note - I'm looking for specific things here. That is, has anyone done the research to see exactly what on the phone operating system is getting messed up that causes this lag (which is discussed all over the internet, with no working solutions). I don't own a mac, so I can't delve into the guts of the iPhone very well to see what's up with it... Some additional info: Reboots (hold down power/home) and "Sleeps" (slide off) do nothing. Only fresh re-installs help I only have about 15 apps installed - sometimes you see the answer to uninstall apps if you have too many, I'd hope that 15 isn't too many, and even when I've had none installed, it still gets hung up after a period of time. This phone is not jailbroken, and it is running the 3.0.1 release.

• What are some techniques to monitor multiple instances of a piece of software?

  - by Geo Ego

  It was recommended that I ask this question here by a member of StackOverflow. I have a piece of self-serve kiosk software that will be running at multiple sites. I'd like to monitor their status remotely. The kiosk application itself is pretty much finished. I am now in the process of creating a piece of software that will monitor all of the kiosks from a central location so that the customer can view particular details remotely (for instance, how many bills are in the acceptor's cash cartridge, what customer is currently logged in, etc.). Because I am in such an early stage of development, my options are quite open. I understand that I'm not giving very many qualifications, but I'd like to try to get a good variety of potential solutions. Some details: Kiosk software is a VB6 app running on Windows Embedded Monitoring software will be run on a modern desktop version of Windows (either XP, Vista, or 7) Database is SQL Server 2008 My initial idea was to develop a .NET app that would simply report the last database transaction for each kiosk at a set interval (say every second or so) but I'd really like for the kiosk software to report its status in real-time. I'm not exactly sure where to begin in terms of what modifications may need to be made to the kiosk software, and what the monitoring software will require. Links to articles on these topics would be most welcome.

• Ping server NETBIOS name returns wrong IP and "Destination host unreachable"

  - by music2myear

  Problem server is Windows 2008 R2 VM running on VMWare ESXi 4 host. Single network adapter manually assigned single IP address (192.168.1.11). When I ping the server from any other network computer, it returns 192.168.1.124 and "Destination host unreachable". Yesterday I found a second network adapter assigned to this server with an IP of 169.254... indicating it had no real valid IP. Using the MAC addresses I determined which adapter was not needed/not wanted, and removed it using VMWare systems. This is the network Printer Server and, understandably, nothing is printing right now. I've looked at the solutions here Why was my ping answered by a different IP address than the one pinged? and they aren't applicable to my situation for the following reasons: Output of arp -a on another computer returns the correct IP address (.1.11) assigned to the correct MAC address, the incorrect IP .1.124 is not listed, and the MAC of the network adapter I removed yesterday is not listed at all. I checked out the Microsoft KB article which listed pretty much my exact symptoms ( http://support.microsoft.com/kb/981953 ) and it says to check binding orders and look for hidden adapters. But there are no hidden adapters, and there is only one Network Adapter listed in the Binding Order list. Essentially, I can communicate from the server TO any other network device, but I cannot communicate from any other network device TO the server. Help! UPDATE: Solution found, see this solution for the details.

• Search inside of text files

  - by Matt

  So here is the situation. I currently run a mail server for my small non-profit company. My mail server (Merak Mail Server) keeps logs in .log files and mail as .tmp files. Essentially these are just text files that are kept on the server. Problem is that when I put text into the "Containing text" field on Windows Explorer, it always misses the files and tells me no results returned. Then when I search the files one by one (painful at best), I find the files I need. Do I not understand the search feature well enough, or maybe I have it indexing wrong. I really don't care what I need to use to search the files, even a third-party app is fine with me, I just want to type an email address into a box and search all of my log files or email files and find out which one I am looking for. It can be Windows Search or something else, as long as I can find a way to get the job done I will be happy. Pay solutions are fine as well. Thanks everyone in advance.

• How do I redirect my website from non-www to WWW using Apache2?

  - by Andrew

  I'm currently trying to set up my personal webpage. I am using a VPS and have manually installed Wordpress, and everything seems to work... except if I go to the non-www version of my website, it comes up with a page not found. www.andrewrockefeller.com <-- Works andrewrockefeller.com <-- Does not (and I want to redirect it to www.andrewrockefeller.com) I have tried adding RewriteEngine functionality to my .htaccess, and that isn't working. I have also tried adding the 'most-voted' method of adding to my default file (which apache2.conf pulls from: <VirtualHost *> ServerName andrewrockefeller.com Redirect 301 / http://www.andrewrockefeller.com/ </VirtualHost> Seeing how many people are able to get the above working, is there something else I may be missing to allow that to function? Thank you for your time! EDIT: My .htaccess file is as follows: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress The #Wordpress section was autocreated when I changed the settings from ?p=1 (ugly links) to prettylinks. Any proposed solutions I've found on here I've tried out and restarted apache2, and it hasn't worked.

• How to fix Quicktime video color problems on nVidia chipset and Windows XP?

  - by Matthew Glidden

  My laptop frequently plays video as if in very low-color mode. Though the sound remains clear, it looks terrible, showing only a few shades of red, blue, or yellow. (It's even worse than 8-bit color.) The problem doesn't happen consistently, so I'm looking for troubleshooting advice or known solutions. I use a Dell Latitude D620 laptop with Windows XP, on-board nVidia video chipset, Quicktime, and multiple monitors (laptop screen + VGA-connected LCD). Color problems happen in each application I tried, iTunes, a browser, and the Quicktime standalone player. It doesn't happen right after reboot, so could be from a sleep-wake cycle, or at least being on for an extended period. Google results suggest reinstalling nVidia drivers, which I've done several times with no change. I have found 2 workarounds. Reboot, sacrificing significant time and disrupting work In nVidia control panel, change color to 16-bit, and then back to 32-bit This happens with all video playback, so it's definitely not one corrupt file. I use workaround #2 consistently, but would love a longer-term solution.

• Free tiered storage automation in linux?

  - by NginUS

  I have a couple virtualized fileservers running in QEMU/KVM on ProxmoxVE. The physical host has 4 storage tiers with significant performance variances. They're attached both locally and via NFS. These will be provided to the fileserver(s) as local disks, abstracted into pools, and handling multiple streams of data for the network. My aim is for this abstraction layer to intelligently pool the tiers. There's a similar post on the site here: Home-brew automatic tiered storage solutions with Linux? (Memory - SSD - HDD - remote storage) in which the accepted answer was a suggestion to abandon a linux solution for NexentaStor. I like the idea of running NexentaStor. It almost fits the bill. NexentaStor provides Hybrid Storage Pools, and I love the idea of checksumming. 16TB without incurring licensing fees is a huge plus as well. After the expense of the hardware, free is about all my budget can handle. I don't know if zfs pools are adaptive or dynamically allocated based on load, but it becomes irrelevant since NexentaStor doesn't support virtio network or block drivers, which is a must in my environment. Then I saw a commercial solution called SmartMove: http://www.enigmadata.com/smartmove.html And it looks like a step in the right direction, but I'm so broke I'd be wasting their time to even ask for a quote, so I'm looking for another option. I'm after a linux implementation that supports virtio drivers, and I'm at a loss as to which software is up to it.

• Storing changes to multiple databases in a single centralized database

  - by B4x

  The setup: multiple MySQL databases at different locations with the same scheme. The databases are in production. The motivation: we want to present information in these databases in a web interface, clearly showing which database the row originated from. We want to be able to get this data from one single source (for different reasons, one of them is pagination which gets tricky if you use multiple sources). The problem: how do we collect data from multiple databases, storing it at a central location and clearly marking the origin of each row? We have discussed using a centralized DB that tracks changes to the production DBs, with the same schema and one additional column for origin. If possible, we would like to avoid having to make changes in the production environment. Since we can't use MySQL's replication (multiple masters to a single slave isn't allowed), what are our other options? Are there any existing solutions for something like this or do we have to code something ourselves? Is the best solution to change the database schemas in production and add a column for origin? The idea of a centralized database isn't set in stone. If there is a solution to this that solves our other problems without a centralized DB, we can be flexible. Any help is much appreciated.

• Almost every Inkscape extension yields an error in Mac OS X

  - by andyvn22

  I've run the latest few versions of Inkscape (currently landed on "0.47+devel"), and have been having trouble with the Extensions menu. So far, in every version of Inkscape I've tried, nearly every extension yields the following error: The fantastic lxml wrapper for libxml2 is required by inkex.py and therefore this extension. Please download and install the latest version from http://cheeseshop.python.org/pypi/lxml/, or install it through your package manager by a command like: sudo apt-get install python-lxml I've tried the instructions listed there, of course, with no effect. I've also found many references to this issue on fora, in bug trackers, etc., and as such also tried: sudo easy_install lxml cd /Applications/Inkscape.app/Contents/Resources/lib mv libxml2.2.dylib libxml2.2.dylib.old ln -s /usr/lib/libxml2.dylib and a few similar solutions. Nothing has produced any change in Inkscape's behavior. Does anyone know A) what's really going on here? Because from what I gather the error is not describing the actual problem. And of course B) a simple solution? I need those features! :)

• Ways to have audio output without wires

  - by viraptor

  I'm trying to find a way of using my home speakers/amp without actually having to connect them. There are two laptops that use them normally (so I don't like changing the connection all the time) and I'd rather move the speakers to a place that's away from the couch. I'm not sure how to do this though... The options I can think of are: some kind of wireless jack-jack connection finally getting a media server Unfortunately I can't find any good product for the first solution. I've seen some headphones which have the receiver integrated and a separate transmitted, so in general the idea is already out there, just not the way I need ;) I've seen also http://www.miccus.com/products/blubridge-mini-jack, but I'd have to have a compatible receiver which I can't find on its own (maybe there's some application that the media server could use?). As far as media server goes... many of the plug servers look really interesting, but I'm not sure how to create an audio output and how to redirect the input really. None of the plug servers I've seen so far advertises the option of audio output jack port. I think this part could be fixed by getting one with an usb port and a separate cheap usb soundcard. I hope that input can be sorted out in some rather simple way. I've got Linux running on both laptops so I hope that would be possible to configure jack/pulse/whatever to use the remote endpoint, or even write a simple local-/dev/dsp:network:media-server-/dev/dsp forwarder. So the main question is... are there better ways? Are there any out of the box solutions? Or maybe this was already done by someone and described somewhere?

• Microsoft SQL Server Management Studio causing system freeze

  - by CRoshanLG

  I'm experiencing very slow response from MSSMS and it causes other applications to slow down. Specially Skype crashes after few seconds from opening MSSMS, showing an error called "Disk I/O Error". I'm regularly using few applications (Sublime text, MS Word, Firefox, Outlook, Skype and one or two other apps) simultaneously. The system works fine when MSSMS is not in use! But as soon as MSSMS is opened, all the apps start to freeze (MSSMS also responds very slow). This problem has been there for about a week now (I haven't installed any apps or haven't made any changes to the system during that time). -- System Specifications -- Processor: Core i3 (3.1 GHz) RAM: 4 GB OS: Windows 7 Professional (64 bit) Free space in C drive: ~ 100 GB MS SQL Server 2008 R2 Microsoft SQL Server Management Studio version - 10.50.1600.1 I've tried to find a reason for this but there are no helpful information in the web! There are some solutions suggested (in forums and in Skype Support pages) for the Skypes' "Disk I/O Error", all of which I tried but does not solve the problem. Has anyone faced the same senario? (and hopefully) knows a solution? Systems Log I don't have much knowledge in interpreting the System Log, but I think the Critical and Warnings are not helpful. But there are lots of Error logs which might be useful. In source Kernal-General there are few similar errors saying "An I/O operation initiated by the Registry failed unrecoverably.The Registry could not flush hive (file): <some file>" In source atapi also there are few similar errors -- "The driver detected a controller error on \Device\Ide\IdePort0." (all errors has occurred in 'IdePort0') In Application Error, there are several errors logged, and following is the latest one. Both the Errors which has occurred today is similar (to this one). As it is from Ssms.exe, I guess this is relevant to the cause of problem. But as I said above I can't understand what it means!

• How to serve pages through multiple frameworks/template engines efficiently

  - by Leftium

  I would like to render a file that has both PHP tags and Web2Py tags mixed together. To do this, I would like the web server to pass the file through Web2Py, then PHP. I found a method to call PHP from Web2py via Python (based on this method for running PHP on top of django), but this method loses the benefits of any server optimizations from mod_php or FastCGI like caching and multi-threaded operation. A new process is created for each PHP request, which is very slow. Is there a better way to efficiently render pages with both Web2Py(Python) and PHP tags in the same file? Note I am not looking for methods of serving PHP-only and Web2Py-only files from the same server/domain. I prefer solutions for Apache2 or Cherokee. I'm open to using other web servers, though. Background info: I prefer to develop in Web2Py, but we have this pre-existing system written in PHP. I would like to augment the PHP system with some of Web2Py's features like auth authentication/user management and the T() internationalization object. Also it would make it much easier to port the PHP project to Web2Py if it could be done piecemeal. Since the PHP project consists of many files, it would greatly help if they did not need modification.

• tail -f and then exit on matching string

  - by Patrick

  I am trying to configure a startup script which will startup tomcat, monitor the catalina.out for the string "Server startup", and then run another process. I have been trying various combinations of tail -f with grep and awk, but haven't got anything working yet. The main issue I am having seems to be with forcing the tail to die after grep or awk have matched the string. I have simplified to the following test case. test.sh is listed below: #!/bin/sh rm -f child.out ./child.sh > child.out & tail -f child.out | grep -q B child.sh is listed below: #!/bin/sh echo A sleep 20 echo B echo C sleep 40 echo D The behavior I am seeing is that grep exits after 20 seconds , however the tail will take a further 40 seconds to die. I understand why this is happening - tail will only notice that the pipe is gone when it writes to it which only happens when data gets appended to the file. This is compounded by the fact that tail is to be buffering the data and outputting the B and C characters as a single write (I confirmed this by strace). I have attempted to fix that with solutions I found elsewhere, such as using unbuffer command, but that didn't help. Anybody got any ideas for how to get this working how I expect it? Or ideas for waiting for successful Tomcat start (thinking about waiting for a TCP port to know it has started, but suspect that will become more complex that what I am trying to do now). I have managed to get it working with awk doing a "killall tail" on match, but I am not happy with that solution. Note I am trying to get this to work on RHEL4.
