• How can I determine what is causing SQL Server 2008 Express to hang Windows 7?

  - by thelaughingdm

  I have SQL Server Express 2008 installed on a Windows 7 (32-bit) developer workstation. Whenever I run an application that accesses SQL Server the Windows 7 shell hangs when the application closes. Applications like Windows Explorer and Task Manager become completely unresponsive. The task bar will not allow any interaction. The only way to recover the system is to power cycle. Two of the applications in use when this happens are NUnit and SQL Server Management Studio. NUnit always runs the unit tests that interact with the database fine. SQL Server Management Studio will sometimes cause the problem while trying to explore the database. The Windows event log does not show any events that are obviously connected to the problem. I have reverted and reinstalled SQL Server Express 2008 several times. What can be done to identify what is causing SQL Server Express 2008 to hang the Windows 7 shell?

• How to protect Ruby on Rails code on external server?

  - by Phil Byobu

  I have to deploy a Ruby on Rails Applications on a client's server and I do not want them to be able to view or modify the source code. How would you protect the code technically? I thought about building a linux-based virtual machine with an encrypted filesystem where the application code resides. The client has no root access, or direct access to the system at all. All services start automatically and the application is ready to use. What would you suggest?

• Efficient way to secure tomcat database connections

  - by Greymeister

  Our customer has a problem with database information in plaintext within a server.xml or context.xml file on the Tomcat server. I've looked at several sites like OWASP and it seems like there's no obvious solution. I've also seen things like this wordpress blog which describe implementing a custom Tomcat extension to do this. There must exist some standard implementation(s) already without having to roll your own. Does anyone have experience with such a solution?

• What should I know before considering a VPS or dedicated server?

  - by Corey Sarnia

  I have a plan for the future for an application and web service. The client will have an application that will send requests to a server-side Java back-end that will process requests, and the server should also be able to host a website, preferably on a WAMP setup (which is what I'm used to; very little *nix knowledge). Now, I cannot provide any hard stats because this is only a plan that's in a discussion stage. However, we do fully expect it will scale enough to need some type of dedicated hosting. My question is this: what types of things should I know about before looking into getting hosting? What should I be asking the hosting providers before I decide on a purchase? When is it appropriate to switch from a VPS to a fully dedicated server?

• Downloading content greater than 2000 bytes from local network hangs in browser on Windows XP

  - by artplastika

  We have web application that runs under Tomcat in a local network. Our customers experience strange problem using this web application. Let's say Tomcat server runs on host1 and we open webapp URL in browser on host2. Any browser on host 2 starts opening page and downloading of content "hangs" for hours. We've made bunch of experiments and found that any content larger than 2000 bytes makes browser request hang. Tried in Internet Explorer 8, Opera 12, Firefox. At the same time if user opens website from internet, it works. Opening webapp from the same host1 where Tomcat is running works normally. Local network is organized with D-Link DGS-3120-48TC switch. Additional info. During experiments we've noticed XP Tweaker installed on hosts. Network settings from that tool: MTU is manually set to 1500 RWIN = 14600 Support of TCP frames larger than 64 KB is on Time to Live = 32 SACK is on

• Setting up apache rewrite rule to only forward if in a directory

  - by wooowoopo

  Hi, I currently have a site setup with the following in httpd.conf: <VirtualHost x.x.x.x:80> ServerName testsite ExpiresActive On ExpiresByType image/gif A2592000 ExpiresByType image/png A2592000 ExpiresByType image/jpg A2592000 ExpiresByType image/jpeg A2592000 ExpiresByType text/css A2592000 ExpiresByType application/x-javascript A1 ExpiresByType text/javascript A1 AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css application/x-javascript text/javascript DocumentRoot /usr/local/www/apache22/data/thesite/trunk RewriteEngine On RewriteRule !\.(htc|js|tiff|gif|css|jpg|png|swf|ico|jar|html|doc|pdf|htm|xml)$ %{DOCUMENT_ROOT}/../platform.php [L] </VirtualHost> Where x.x.x.x is my IP. At the moment it forwards anything which is not in the set (htc|js|tiff|gif|css|jpg|png|swf|ico|jar|html|doc|pdf|htm|xml) to platform.php How htp://x.x.x.x/phpmyadmin to also forward. Would it be possible to only perform this rewrite conidtion if I am in a subdirectory. Eg. http://x.x.x.x/projectone So htp://x.x.x.x/projectone/login would direct to the platform.php Thanks

• How to restrict HTTP Methods

  - by hemalshah

  How can I restrict HTTP methods to those required by the MOSS07 application(s) using IIS6? Update This is what was written in the document IIS6 should be used to restrict HTTP methods to those required by the MOSS07 application(s). I also searched some books and saw something curious in O'Reilly's Sharepoint 2007 by James Pyles and others. There is no real suppported way to use HTTP POST and HTTP GET because of the web.config settings and the static definition of the WSDL. In the web.config <protocols> <remove name="HttpGet"> <remove name="HttpPost"> <remove name="HttpPostLocalHost"> <add name="Documentation"> </protocols> If we do this in the Web.Config file, would it solve the problem?

• Has ec2 made self-hosting possible for 'amateur' sysadmins possible?

  - by Blankman

  I'm a developer, and it seems ec2 has made it possible for a amateur sysadmin like me to setup and maintain a fairly large set of servers. Now I don't mean to undermine real sys admins, as I know the value of them but what I am trying to get at is that someone like me can setup and maintain a cluster of servers (front end web servers, with some db servers) using tools like ec2 and capistrano with the help of google. Now this isn't something I would do as a long term thing, but as a startup, one-man operation, I think I can pull this off until business takes off and I can hire this important role out. With ec2, I get my firewall, so I basically open up port 80 on my public facing server, which will run haproxy and route requests to my cluster of servers. Ofcourse I am simplifying the setup, but just want a feel for what you guys think about my perception. My application is a web application, that will be runing Ruby on rails (passenger) and talking to mysql or postgresql.

• Launch apps or run commands on Windows via shortcuts

  - by Francisc

  Is it possible to register shortcuts on Windows 7 so that regardless where you are looking (Desktop, a folder etc) the shortcut gets "heard" and the appropriate action is performed. For example, creating a shortcut in the System32 folder which will work if you use Run with the shortcut's name, will not work if you set a key combination when focus is set on the Desktop for example. Is there a native way of registering top-level shortcuts or even an application for enabling this? Example of things I want keyboard shortcuts for: open a specific folder like %path% create a new .js file in the current folder launch an application eventually with its path set to the current location if the app supports this (e.g. command prompt) Thank you.

• Django fails to find static files served by nginx

  - by Simon

  I know this is a really noobish question but I can't find any solution despite finding the problem trivial. I have a django application deployed with gunicorn. The static files are served by the nginx server with the following url : myserver.com/static/admin/css/base.css. However, my django application keep looking for the static files at myserver.com:8001/static/admin/css/base.css and is obviously failing (404). I don't know how to fix this. Is it a django or an nginx problem ? Here is my nginx configuration file : server { server_name myserver.com; access_log off; location /static/ { alias /home/myproject/static/; } location / { proxy_pass http://127.0.0.1:8001; proxy_set_header X-Forwarded-Host $server_name; proxy_set_header X-Real-IP $remote_addr; add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM NAV"'; } } Thanks for the help !

• Problem with screen redrawing at DOS app in VmWare Player

  - by MicTech

  I have very old DOS Application (CadSoft Eagle - PCB Designer) and I want to work with it on my workstation with Windows 7. Then I install Windows 98 and that software into VmWare Player. But that software has serious problem with redrawing screen. It's very slow in comparison with my Intel Celeron 333MHz with Windows 98. I have same problem if I try to use DOSBox on Windows XP (same Celeron 333MHz). I also trying run this application directly on Windows XP (same Celeron 333MHz) with compatibility mod set to "Windows 98", but I get "(0Dh): General Protection Fault". Can someone give me good advice how I solve that?

• PHP 5 will not work in Centos 6 for me

  - by LaserBeak

  Just created a new install of Centos 6.0 64-bit on a virtual machine and running on Vmware workstation 8, windows host. yum install php service httpd restart And when trying to run a html file from the var\www\html dir which just has <?php phpinfo(); ?> in it or pointing browser to localhost. Nothing comes up. Also opened up httpd.conf and added: AddType application/x-httpd-php .php AddType application/x-httpd-php-source .phps Tried reinstalling, installing php-common, then php etc. to no avail. Otherwise going for the typical LAMP. installed: php.x86_64 5.3.2-6.el6_0.1 @updates php-cli.x86_64 5.3.2-6.el6_0.1 @updates php-common.x86_64 5.3.2-6.el6_0.1 @updates Yet to update to Centos 6.1 PHP5 is probably comes installed by default with Centos and I maybe stuffed it up by running yum install php?

• How to reliably run a batch job every 5 seconds?

  - by Benjamin

  I'm building an application where the sending of all notifications (email, SMS, fax) will be asynchronous. The application will write the notifications to the database, and a batch job will read these notifications and send them with the appropriate transport. I was first reading at ways to run cron faster than the minute, and realized this was a bad idea. The batch scripts are written in PHP, and I guess that writing a proper daemon would be quite an overhead (though I'm open to any suggestion, as PHP car run indefinitely as well). What I have in mind is a solution that would: Run the PHP script every 5 seconds Check that the previous run has finished, or abort (never 2 concurrent batches running) Kill the script if live for more than x minutes (a security in case it hangs) Start with the system (if a reboot occurs) Any idea how to do this?

• Windows 7 XPS Document Writer has stopped working

  - by jamie

  I have successfully used the Windows 7 XPS Document writer for quite a while under windows 7 (64 bit). Now however when i try to print i get prompted twice for the output file name and then get different error messages depending upon the application being used. e.g. Notepad gives a 'The I/O operation has been aborted because of either a thread exit or an application request'. I have disabled and reenabled the XPS facilities of windows features and have similiarly removed and readded the printer. But the end result is the same. I've uninstalled all applications i have installed since the time when i know it worked but this also has not made any difference. Suggestions please!

• How to link data in different worksheets

  - by user2961726

  I tried consolidation but I can not get the following to work as it keeps saying no data consolidated. Can somebody try this dummy application and if they figure out how to do the following below can give me a step by step guide so I can attempt myself to learn. I'm not sure if I need to use any coding for this: In the dummy application I have 2 worksheets. One known as "1st", the other "Cases". In the "1st" worksheet you can insert and delete records for the "Case" table at the bottom, what I want to do is insert a row into the Case Table in worksheet "1st" and enter in the data for that row. What should happen is that data should be automatically be updated in the table in the "Cases" worksheet. But I can't seem to get this to work. Also if I delete a row from the table in Worksheet "1st" it should automatically remove that record from the "Cases" worksheet table. Please help. Below is the spreadsheet: http://ge.tt/8sjdkVx/v/0

• Changing size of window when testing Adobe AIR mobile applications

  - by Peter

  Im making a mobile phone Android application in Flash CS 5.5. I set the width/height of the stage to 480/800 px. When I hit CTRL+ENTER to test run the application I get a window that is 480/800 px. It cannot be resized. I want to change the size of that window WITHOUT changing the stage width/height. For example if I run the APK on a mobile phone with a 1000x1000 display the flash will scale automatically to fit the 480/800 stage to the 1000x1000 screen. So it should be possible to change the window size to 1000x1000 without having to change the stage width/height. But how?
