• Easy to use database with views for a medical student doing research?

  - by Sarah

  I'm having trouble finding a tool that does this for my friend (without designing it myself). What is needed is a simple program with a database where input forms and views can be designed and saved. A patient table might consist of, say, 50 columns, so it is imperative that it is possible to make columns be able to default, say, through a form for submission of data. By views I mean something like "saved selections" based on various criteria (WHERE runny_nose=True...) but as friendly as possible to save, and export options would be nice. Does this exist at all? It seems at one hand trivial and on the other, my Google fu is failing.

• Upgrade Subversion 1.6 to 1.7 on CentOS? (can't find yum repository)

  - by user743919

  I want to upgrade my SVN Server from 1.6 to 1.7. Unfortunately I can't find anything on the internet how to do this with yum. I have checked rpmforge-extras but it has only svn 1.6 and not 1.7 I wanted to update with yum because this is the most secure way for me. I'm not an experienced Linux user. Is there a yum repository that contains 1.7 (subversion.x86_64 0:1.7.xxxxx.el5.rfx) I hope somebody can help me out? If there is non, perhaps a short explenation how to update with just step by step.

• PC3200 RAM in Older Computer?

  - by skaz

  Hello all, I am inheriting a Dell Dimension 8200, but it needs RAM to get up and running. I have PC3200 sticks lying around, but I am not sure how to go about figuring out if the RAM is compatible, as RAM has always confused me. Here is the Dell Dimension 8200 Tech Specs: http://support.dell.com/support/edocs/systems/dim8200/specs.htm For RAM, it says: Memory type PC800 (non-ECC) I don't know if that is just the kind that comes with it, and I can put in PC3200 (I think, if it worked, this would run at the lower rating? Is that true?), or if that means only PC800 is compatible. Any help would be appreciated.

• How do I install Visual Studio 2010 Express somewhere besides C:?

  - by TwentyMiles

  I have a SSD as my primary (C:) drive, mainly used for quickly loading games. It's pretty small (~30 GB) so I want to keep things that don't really need a speed boost off of it. I attempted installing the Visual Studio 2010 Express beta last night, and It claimed to require 2.1 GB of space so I changed the install directory to a secondary, non-SSD drive. After this, the installer said that it would use 1.8 GB on C: and ~200 MB on the secondary drive. While this token gesture of moving 1/10 of the app to the place I told it to is cute, I really want to install everything I can to the secondary drive. Is there any way to install all of Visual Studio 2010 Express to a drive besides C:?

• How badly do SSDs degrade without TRIM?

  - by joev

  SSDs have been out for a few years, and have seen all kinds of usage patterns. Windows and Linux support the TRIM command, with Mac OS still trailing behind here. Update (2 Aug 2011): It appears OSX Lion has support for TRIM in Apple-branded SSDs. There is a utility that enables TRIM in non-Apple SSDs I'm sure plenty of Mac users (and pre-TRIM version of Win/Linux) have SSDs. So, to you folks: have you noticed a degradation of SSD performance during its lifetime? How long have you been using the SSD, and how bad is the degradation? I'm assuming that even at its most degraded state, a modern SSD would still smoke a traditional hard drive in terms of performance.

• Do TCP/UDP connections add to the Windows incoming connection limit?

  - by user47899

  Hi all, I've tried to figure out what Microsoft means by "Windows sockets" and it all seems very vague. Basically we have customers that sometimes try to set up workgroups with close to 10 Windows XP computers with drive and printer shares and we're worried that some of the non-Windows Ethernet devices on the network will cause issues with the inbound connection limit outlined here where only 10 inbound connections can be active at one time. For example, there is an Ethernet Caller ID device that broadcasts UDP packets to all computers, and a kitchen display system that likewise broadcasts UDP. They may also have incoming TCP packets for our custom online ordering module. Do these TCP/UDP connections count toward the inbound connection limit? I'm aware that Windows 7 has increased the limit to 20 but we might have future customers that will push that limit. Thanks in advance

• Redirecting traffic to a https site

  - by Saif

  In our mail server there are multiple virtual email domain hosted. User can use webmail.example.com (this is the first apache virtualhost) to check mail or they can use mail.THEIR-DOMAIN.com. If the put mail.THEIR-DOMAIN.com apache shows the webmail.example.com as it is the first virtualhost and mail.THEIR-DOMAIN.com doesn't exist. Recently we imposed https for webmail.example.com and added this mod_rewrite rule: RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} But now users not getting the default webmail page as they were getting before. How can we redirect all request coming to the URL "mail.ANY-DOMAIN.com" to "https://webmail.example.com"? I've tried the following but it didn't work: RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (mail.*) https://webmail.example.com Thanks for your help in advance.

• backing up ntfs disk using rsync on ubuntu

  - by user70366

  For a long time I was using windows. I have a separate drive I use to keep copies of my media files, photos etc. on, which I periodically backup to an external drive. In Windows I used SyncToy to do this. After my Windows stopped booting, I decided to switch to Linux (Ubuntu 10.10). That seems to be going fine, but now I want to backup my drive to the external drive like before. Mostly the two drives will be already the same with maybe about 10GB of extra files added. So I try to use rsync to synchronise the two drives like this: rsync --dry-run -rvlt --modify-window=1 /media/Antonio1TB/Backup /media/FREECOM\ HDD/Backup The problem is the dry run indicates that every file on the drive will be copied. Not just the files I have recently added. What is the correct command to synch two NTFS drives under Ubuntu so that files that already exist don't get copied again? Thanks.

• Apache mod_rewrite - remove extension/add trailing slash/preserve directory structure

  - by Henry Wrinkler

  I am currently using the following .htaccess file to remove the .php extension from my files and add a trailing slash to all URLs: RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.php -f RewriteRule ^([^/]+)/$ $1.php # Forces a trailing slash to be added RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$ RewriteRule (.*)$ /$1/ [R=301,L] This is working great, however, when I have a php file in a directory, and I want to serve that file from a directory I get a 404 error. Is there a way to do this with 1 .htaccess file in the root. I really don't want to remember to put a .htaccess file in each directory. Right now www.myexample.com/information/ Serves /information.php. Great! However www.myexample.com/categories/category-1/ this throws a 404 even though the file /categories/category-1.php does exist. I would like to modify my .htaccess file so this serves /categories/category-1.php.

• How to delete a faulty FTP connection in Aptana?

  - by Peter

  Hi, I just created an FTP connection in Aptana in which I made a mistake. I told Aptana to remember it anyway while I looked up the correct data (user/password and such). Now I want to edit the FTP connection but as soon as I click it tries to connect which results in an error. If I try to delete it, same story, it tries to connect and I get the error and the delete doesn't go through. So, I have a non working FTP connection that I can't delete nor edit.How do I get rid of this thing? Or how do I correct it? Cheers.

• Does Windows 8 support the "start in [folder]" property for shortcuts?

  - by FumbleFingers

  I use Foobar2000 to play music, and for years now I've run it in what they call "portable mode". What that means is that the program itself isn't actually "installed" in the traditional Windows sense. All "non-system" dll's required by the application are in the same folder as the executable; earlier versions of Windows find them there, and everything runs fine. But Windows 8 fails because it doesn't find them. I want things set up this way because I keep Foobar2000 on a portable external hard drive, so I can just move it between different computers without having to go through the Windows install process. With all previous versions of Windows, I could either directly run the application from File Explorer, or create a shortcut on the desktop with the "start in folder" property set to the actual folder containing the program. I can still use the first method, but I want a shortcut! Is there any way to do what I want?

• Help recovering lost text from a refreshed Chrome webpage (it was in the clipboard as well)? [closed]

  - by tobeannounced

  Possible Duplicate: Chrome: where is the location to save browse temporary files Ok, so here's what happened - and yes, it was pretty stupid by me: I wrote up and submitted a post on Stack Overflow It was not suited to be placed on Stack Overflow as someone pointed out to me, so I deleted the post (this was a few hours ago) I copied the text into a new question page on Super User, but didn't submit it yet I accidentally just refreshed the webpage that had the text, and the question has now been deleted from Stack Overflow I have Lazarus installed, however the Chrome version doesn't have many features and the text was not recoverable from there. I do not have a clipboard manager, but the text was copied to my clipboard - so is there any way to get this back (Windows 7)? Although the post on Stack Overflow was deleted, I suppose it would have existed in my cache - could I recover it from there? Would the post on Stack Overflow exist in an rss feed anywhere? Many thanks, and I hope I can find this - and I am sure that the solution will prove valuable for me (and others) in the not too distant future once again.

• Setting up Apache directory root behavior

  - by Corey

  I'm running Apache on a Windows machine for local testing and I'm new to it. Currently, if I navigate to localhost/ in a web browser, it will display an index.html page if one exists. Otherwise, it will display the directory listing. How can I make it so that navigating to a root directory will display more than index.html? What I need is so that if either: index.html, index.htm, or index.php exist, it will navigate to one of those. How can I disable showing directory roots? I would like it to return a 403 Forbidden error if no index page exists.

• Configuring MPI on 2 nodes

  - by Wysek

  I'm trying to create really simple "cluster" from 2 multicore computers using openmpi. My problem is that I can't find any tutorials on that matter. I don't want to use torque because it's not necessary in my case nevertheless all tutorials give configuration details either about torque or mpd (which doesn't exist in openmpi implementation). Could you give me some tips or links to appropriate manuals? Steps I've already completed: - openmpi installation - network configuration (computers see each other) - ssh password-less login to second computer I tried using machinefiles without further configuration and with just 2 IPs in it. But jobs don't seem to start at all after initialization part. (MPI seems to work because I'm able to scatter jobs on multiple cores of both computers without communication between them).

• How to disable the Windows 8 lock screen, without disabling the password?

  - by zeel

  Windows 8 now has a slide-away lock screen like so many other OSes designed for a touch interface. However on a non-touch PC/laptop this is just an extra annoying step in logging in. There is an option to disable it, but this also turns off the password requirement. Is there a way to disable the lock screen, and have Windows wake up directly to the password entry screen? Often when pressing a key to hide it there will be a noticeable delay before password entry is accepted, and no indicator, so one can easily lose the first character or so that they attempt to type, thus failing the login attempt.

• Run 2008 R2 Service under 2000 Domain Account

  - by NoDisassemble

  I'm trying to get a service to run under a domain account. When I try to add the account, I get the error The account name is invalid or does not exist, or the password is invalid for the account name specified I know the account exists and the password is correct. I am also having trouble adding it manually to the "Log on as a service" setting, I get the error An extended error has occured. Failed to save Local Policy Database After a day of research I'm starting to suspect it has to do with it being a 2008 R2 server trying to use a 2000 domain account. I've tried to change the LAN Manager authentication level and the Minimum session security looks okay per my Google digging. I'm not sure what else I can do?

• Own mediawiki/wikipedia naming convention for pages

  - by Andy M

  I recently installed a mediawiki at home and I'm looking for a way to name pages. Let's say I have the following structure : Main - Dev - C# - Tips Main - Cooking - Mexixan Cooking - Tips Main - Annoying my girlfriend - Tips Each final page is a different Tips page. Naming them only "tips" won't work because I need three different pages. Now, I could name each of my tips page with its "path" (ex: main_cooking_mexican_cooking_tips) but it looks cumbersome and the problem is that, whenever I'll change the structure of my mediawiki, some pages will need to change their name in order to be corrects. Does it exist some convention to follow regarding this ? Thanks for your help !

• How to Reset Windows 7 to its default font for the whole system?

  - by Fellknight

  This might sound a little bit silly but please bear with me. Somehow I changed my default display font, the one that Windows uses for system dialog boxes, accept/cancel buttons, pretty much everything in the system (it even goes as far as to change how my the text in my web browser appears). Now everything that it's affected looks like under the effects of the bold button in office (very black and very thick words). This is an inconvenience for example on some mail accounts who use this effect to display unread messages. Is there any way to return it to its default state, non "bold" typography for the whole system?

• How do I remotely run a Powershell workflow that uses a custom module?

  - by drawsmcgraw

  I have a custom Powershell module that I wrote for various tasks. Now I want to craft a workflow whose activities will use commands from the module. Here's my test workflow: workflow New-TestWorkflow{ InlineScript { Import-Module custom.ps1 New-CommandFromTheModule } } Then I run the workflow with: New-TestWorkflow -PSComputerName remoteComputer When I do this, the import fails because it can't find the module. I imagine this is because the workflow is executing on the remote machine, where my module does not exist. I can see myself running this across many machines so I'd really rather not have to install this module and maintain it on all of the machines. Is there some way to have my module in a central place and use it in workflows?

• What is the best way to compare vhost traffic?

  - by Bob Flemming

  Recently one of my servers has been subjected to malicious ddos attacks. I have about 12 websites hosted on the server which uses name based v-hosting. I am trying to identify which virtual host(s) are getting bombarded with traffic. I have used tools such as iftop which is good for identifying hosts which are consuming lots of bandwidth, and also apachetop which is useful for identifying which resources are being requested on a single v-host. What I really need is a tool which allows me to see the amount of traffic being received by each v-host in real time so I can easily see which v-host is being targeted. Does such a tool exist?

• How do I debug an upstart job?

  - by Cerales

  I have the following job in /etc/init/collector: start on runlevel [2345] stop on runlevel [!2345] expect daemon exec /usr/bin/twistd -y /path/to/my/tac/file When I start the job with sudo service collector start, it hangs. If I ctrl-c and run initctl list, I see this: collector start/killed, process 616 I can't see an instance of the twistd daemon in ps, and the HTTP server it's supposed to be providing does not exist. I even tried this without 'expect daemon' and with a simple call to a one-line bash script using a script stanza, and it still doesn't work. I think I'm doing something very wrong. What could it be?

• Missing time zones in OSX and Windows

  - by pellepim

  I am working on a javascript to automatically detect a user's timezone (https://bitbucket.org/pellepim/jstimezonedetect/). But there are two timezones that I have a really hard time to test, since I can not set my system to observe these timezones. The timezones I am talking about are UTC+1245 (Chatham Islands, NZ) and UTC+0845 (Australia/Eucla). As far as I can tell in OSX (Snow Leopard) and in Windows 7 these timezones do not exist as a setting. Granted, very few people live in these areas, and it might just not be worth it. Does anyone know of a way to set these timezones on a system level? In any operating system? If it is not possible in a trivial way, what do people who live in these areas do to get their systems working as they would like?
