• Unix list absolute file name

  - by Matthew Adams

  Given an arbitrary single argument representing a file (or directory, device, etc), how do I get the absolute path of the argument? I've seen many answers to this question involving find/ls/stat/readlink and $PWD, but none that suits my need. It looks like the closest answer is ksh's "whence" command, but I need it to work in sh/bash. Assume a file, foo.txt, is located in my home directory, /Users/matthew/foo.txt. I need the following behavior, despite what my current working directory is (I'm calling the command "abs"): (PWD is ~) $ abs foo.txt /Users/matthew/foo.txt $ abs ~/foo.txt /Users/matthew/foo.txt $ abs ./foo.txt /Users/matthew/foo.txt $ abs /Users/matthew/foo.txt /Users/matthew/foo.txt What would "abs" really be? TIA, Matthew

• Mac gcc non-virtual thunk error

  - by fret

  I'm getting these non-virtual thunk errors only in the Deployment build of my app. It uses a private framework called Lgi. Building on 10.5.8 using XCode 3.1.4 (latest for leopard?) The error looks like this: Ld /Users/matthew/Code/Scribe-Branches/v2.00/build/Development/Scribe.app/Contents/MacOS/Scribe normal i386 cd /Users/matthew/Code/Scribe-Branches/v2.00 /Developer/usr/bin/g++-4.0 -arch i386 -L/Users/matthew/Code/Scribe-Branches/v2.00/build/Development -F/Users/matthew/Code/Scribe-Branches/v2.00/build/Development -F/Users/matthew/Code/Lgi/build -F/Users/matthew/Code/Scribe-Branches/v2.00/../../Lgi/build/Development -F/Users/matthew/Code/Scribe-Branches/v2.00/../../Lgi/build/Development -F/Users/matthew/Code/Scribe-Branches/v2.00/../../Lgi/build/Deployment -F/Users/matthew/Code/Scribe-Branches/v2.00/../../Lgi/build/Development -F/Users/matthew/Code/Scribe-Branches/v2.00/../../Lgi/build/Deployment -filelist /Users/matthew/Code/Scribe-Branches/v2.00/build/Scribe.build/Development/Scribe.build/Objects-normal/i386/Scribe.LinkFileList -framework Carbon -framework Lgi -o /Users/matthew/Code/Scribe-Branches/v2.00/build/Development/Scribe.app/Contents/MacOS/Scribe Undefined symbols: "non-virtual thunk to GWindow::OnDrop(char*, GVariant*, GdcPt2, int)", referenced from: vtable for ScribeWndin ScribeApp.o vtable for GShutdownin ScribeApp.o vtable for CalendarUiin Calendar.o vtable for CalendarViewWndin CalendarView.o vtable for CalendarConfigin CalendarView.o vtable for ScribeExportin Exp_Scribe.o vtable for GNewMailDlgin GNewMailDlg.o ....etc for lots of classes.... Anyway I know I'm not leaving those undefined because it does in fact link and run fine in the development build. Now after googling the issue the first thing to try is changing the optimization setting, which I did... and no dice. Some link error. So these virtual functions are initially defined in GDragDropTarget, and GWindow's inheritance looks like this: class LgiClass GWindow : public GView #ifndef WIN32 , public GDragDropTarget #endif (LgiClass being for __declspec export/import on win32) Any ideas on what to try next? Maybe I need to provide more info.

• Complete Guide to Symbolic Links (symlinks) on Windows or Linux

  - by Matthew Guay

  Want to easily access folders and files from different folders without maintaining duplicate copies?  Here’s how you can use Symbolic Links to link anything in Windows 7, Vista, XP, and Ubuntu. So What Are Symbolic Links Anyway? Symbolic links, otherwise known as symlinks, are basically advanced shortcuts. You can create symbolic links to individual files or folders, and then these will appear like they are stored in the folder with the symbolic link even though the symbolic link only points to their real location. There are two types of symbolic links: hard and soft. Soft symbolic links work essentially the same as a standard shortcut.  When you open a soft link, you will be redirected to the folder where the files are stored.  However, a hard link makes it appear as though the file or folder actually exists at the location of the symbolic link, and your applications won’t know any different. Thus, hard links are of the most interest in this article. Why should I use Symbolic Links? There are many things we use symbolic links for, so here’s some of the top uses we can think of: Sync any folder with Dropbox – say, sync your Pidgin Profile Across Computers Move the settings folder for any program from its original location Store your Music/Pictures/Videos on a second hard drive, but make them show up in your standard Music/Pictures/Videos folders so they’ll be detected my your media programs (Windows 7 Libraries can also be good for this) Keep important files accessible from multiple locations And more! If you want to move files to a different drive or folder and then symbolically link them, follow these steps: Close any programs that may be accessing that file or folder Move the file or folder to the new desired location Follow the correct instructions below for your operating system to create the symbolic link. Caution: Make sure to never create a symbolic link inside of a symbolic link. For instance, don’t create a symbolic link to a file that’s contained in a symbolic linked folder. This can create a loop, which can cause millions of problems you don’t want to deal with. Seriously. Create Symlinks in Any Edition of Windows in Explorer Creating symlinks is usually difficult, but thanks to the free Link Shell Extension, you can create symbolic links in all modern version of Windows pain-free.  You need to download both Visual Studio 2005 redistributable, which contains the necessary prerequisites, and Link Shell Extension itself (links below).  Download the correct version (32 bit or 64 bit) for your computer. Run and install the Visual Studio 2005 Redistributable installer first. Then install the Link Shell Extension on your computer. Your taskbar will temporally disappear during the install, but will quickly come back. Now you’re ready to start creating symbolic links.  Browse to the folder or file you want to create a symbolic link from.  Right-click the folder or file and select Pick Link Source. To create your symlink, right-click in the folder you wish to save the symbolic link, select “Drop as…”, and then choose the type of link you want.  You can choose from several different options here; we chose the Hardlink Clone.  This will create a hard link to the file or folder we selected.  The Symbolic link option creates a soft link, while the smart copy will fully copy a folder containing symbolic links without breaking them.  These options can be useful as well.   Here’s our hard-linked folder on our desktop.  Notice that the folder looks like its contents are stored in Desktop\Downloads, when they are actually stored in C:\Users\Matthew\Desktop\Downloads.  Also, when links are created with the Link Shell Extension, they have a red arrow on them so you can still differentiate them. And, this works the same way in XP as well. Symlinks via Command Prompt Or, for geeks who prefer working via command line, here’s how you can create symlinks in Command Prompt in Windows 7/Vista and XP. In Windows 7/Vista In Windows Vista and 7, we’ll use the mklink command to create symbolic links.  To use it, we have to open an administrator Command Prompt.  Enter “command” in your start menu search, right-click on Command Prompt, and select “Run as administrator”. To create a symbolic link, we need to enter the following in command prompt: mklink /prefix link_path file/folder_path First, choose the correct prefix.  Mklink can create several types of links, including the following: /D – creates a soft symbolic link, which is similar to a standard folder or file shortcut in Windows.  This is the default option, and mklink will use it if you do not enter a prefix. /H – creates a hard link to a file /J – creates a hard link to a directory or folder So, once you’ve chosen the correct prefix, you need to enter the path you want for the symbolic link, and the path to the original file or folder.  For example, if I wanted a folder in my Dropbox folder to appear like it was also stored in my desktop, I would enter the following: mklink /J C:\Users\Matthew\Desktop\Dropbox C:\Users\Matthew\Documents\Dropbox Note that the first path was to the symbolic folder I wanted to create, while the second path was to the real folder. Here, in this command prompt screenshot, you can see that I created a symbolic link of my Music folder to my desktop.   And here’s how it looks in Explorer.  Note that all of my music is “really” stored in C:\Users\Matthew\Music, but here it looks like it is stored in C:\Users\Matthew\Desktop\Music. If your path has any spaces in it, you need to place quotes around it.  Note also that the link can have a different name than the file it links to.  For example, here I’m going to create a symbolic link to a document on my desktop: mklink /H “C:\Users\Matthew\Desktop\ebook.pdf”  “C:\Users\Matthew\Downloads\Before You Call Tech Support.pdf” Don’t forget the syntax: mklink /prefix link_path Target_file/folder_path In Windows XP Windows XP doesn’t include built-in command prompt support for symbolic links, but we can use the free Junction tool instead.  Download Junction (link below), and unzip the folder.  Now open Command Prompt (click Start, select All Programs, then Accessories, and select Command Prompt), and enter cd followed by the path of the folder where you saved Junction. Junction only creates hard symbolic links, since you can use shortcuts for soft ones.  To create a hard symlink, we need to enter the following in command prompt: junction –s link_path file/folder_path As with mklink in Windows 7 or Vista, if your file/folder path has spaces in it make sure to put quotes around your paths.  Also, as usual, your symlink can have a different name that the file/folder it points to. Here, we’re going to create a symbolic link to our My Music folder on the desktop.  We entered: junction -s “C:\Documents and Settings\Administrator\Desktop\Music” “C:\Documents and Settings\Administrator\My Documents\My Music” And here’s the contents of our symlink.  Note that the path looks like these files are stored in a Music folder directly on the Desktop, when they are actually stored in My Documents\My Music.  Once again, this works with both folders and individual files. Please Note: Junction would work the same in Windows 7 or Vista, but since they include a built-in symbolic link tool we found it better to use it on those versions of Windows. Symlinks in Ubuntu Unix-based operating systems have supported symbolic links since their inception, so it is straightforward to create symbolic links in Linux distros such as Ubuntu.  There’s no graphical way to create them like the Link Shell Extension for Windows, so we’ll just do it in Terminal. Open terminal (open the Applications menu, select Accessories, and then click Terminal), and enter the following: ln –s file/folder_path link_path Note that this is opposite of the Windows commands; you put the source for the link first, and then the path second. For example, let’s create a symbolic link of our Pictures folder in our Desktop.  To do this, we entered: ln -s /home/maguay/Pictures /home/maguay/Desktop   Once again, here is the contents of our symlink folder.  The pictures look as if they’re stored directly in a Pictures folder on the Desktop, but they are actually stored in maguay\Pictures. Delete Symlinks Removing symbolic links is very simple – just delete the link!  Most of the command line utilities offer a way to delete a symbolic link via command prompt, but you don’t need to go to the trouble.   Conclusion Symbolic links can be very handy, and we use them constantly to help us stay organized and keep our hard drives from overflowing.  Let us know how you use symbolic links on your computers!

• Test All Features of Windows Phone 7 On Your PC

  - by Matthew Guay

  Are you developer or just excited about the upcoming Windows Phone 7, and want to try it out now?  Thanks to free developer tools from Microsoft and a new unlocked emulator rom, you can try out most of the exciting features today from your PC. Last week we showed you how to try out Windows Phone 7 on your PC and get started developing for the upcoming new devices.  We noticed, however, that the emulator only contains Internet Explorer Mobile and some settings.  This is still interesting to play around with, but it wasn’t the full Windows Phone 7 experience. Some enterprising tweakers discovered that more applications were actually included in the emulator, but were simply hidden from users.  Developer Dan Ardelean then figured out how to re-enable these features, and released a tweaked emulator rom so everyone can try out all of the Windows Phone 7 features for themselves.  Here we’ll look at how you can run this new emulator image on your PC, and then look at some interesting features in Windows Phone 7. Editor Note: This modified emulator image is not official, and isn’t sanctioned by Microsoft. Use your own judgment when choosing to download and use the emulator. Setting Up Emulator Rom To test-drive Windows Phone 7 on your PC, you must first download and install the Windows Phone Developer Tools CTP (link below).  Follow the steps we showed you last week at: Try out Windows Phone 7 on your PC today.  Once it’s installed, go ahead and run the default emulator as we showed to make sure everything works ok. Once the Windows Phone Developer Tools are installed and running, download the new emulator rom from XDA Forums (link below).  This will be a zip file, so extract it first. Note where you save the file, as you will need the address in the next step. Now, to run our new emulator image, we need to open the emulator in command line and point to the new rom image.  To do this, browse to the correct directory, depending on whether you’re running the 32 bit or 64 bit version of Windows: 32 bit: C:\Program Files\Microsoft XDE\1.0\ 64 bit: C:\Program Files (x86)\Microsoft XDE\1.0\ Hold your Shift key down and right-click in the folder.  Choose Open Command Window here. At the command prompt, enter XDE.exe followed by the location of your new rom image.  Here, we downloaded the rom to our download folder, so at the command prompt we entered: XDE.exe C:\Users\Matthew\Downloads\WM70Full\WM70Full.bin The emulator loads … with the full Windows Phone 7 experience! To make it easier, let’s make a shortcut on our desktop to load the emulator with the new rom directly.  Right-click on your desktop (or any folder you want to create the shortcut in), select New, and then Shortcut. Now, in the box, we need to enter the path for the emulator followed by the location of our rom.  Both items must be in quotes.  So, in our test, we entered the following: 32 bit: “C:\Program Files\Microsoft XDE\1.0\” “C:\Users\Matthew\Downloads\WM70Full\WM70Full.bin” 64 bit: “C:\Program Files (x86)\Microsoft XDE\1.0\” “C:\Users\Matthew\Downloads\WM70Full\WM70Full.bin” Make sure to enter the correct location of the new emulator rom for your computer, and keep both items in separate quotes.  Click next when you’ve entered the location. Name the shortcut; we named it Windows Phone 7, but simply enter whatever you’d like.  Click Finish when you’re done. You should now have a nice Windows Phone icon and your fully functional shortcut!  Double-click it to run the Windows Phone 7 emulator as above. Features in the Unlocked Windows Phone 7 Emulator So let’s look at what you can do with this new emulator.  Almost everything you’ve seen in demos from the Mobile World Conference and Mix’10 are right here for you to play with.  Here’s the application menu, which you can access by clicking on the arrow on the top of the home screen, which shows how much stuff they’ve got in this!   And, of course, even the home screen itself shows much more activity than it did in the original emulator. Let’s check out some of these sections.  Here’s Zune running on Windows Phone 7, and the Zune Marketplace.  The animations are beautiful, so be sure to check this out yourself. The new picture hub is much nicer than any picture viewer included with Windows Mobile in the past…   Stay productive, and on schedule with the new Calendar. The XBOX hub gives us only a hint of things to come, and the links to games now are simply placeholders. Here’s a look at the Office hub.  This doesn’t show up on the homescreen right now, but you can access it in the applications menu.  Office obviously still has a lot of work left on it, but even at a glance here it looks like it includes a lot more functionality than Office Mobile in Windows Mobile 6. Here’s a look at each of the three apps: Word, Excel, and OneNote, and the formatting pallet in Office apps.   This emulator also includes a lot more settings than the default one, including settings for individual applications. You can even activate the screen lock, and try out the lift-to-peek-or-unlock feature… Finally, this version of Windows Phone 7 includes a very nice SystemInfo app with an advanced task manager.  We hope this is still available when the actual phones are released. Conclusion If you’re excited about the upcoming Windows Phone 7 series, or simply want to learn more about what’s coming, this is a great way to test it out.  With these exciting new hubs and applications, there’s something here for everyone.  Let us know what you like most about Windows Phone 7 and what your favorite app or hub is.

• SQL SERVER – CTE can be Updated

  - by Pinal Dave

  Today I have received a fantastic email from Matthew Spieth. SQL Server expert from Ohio. He recently had a great conversation with his colleagues in the office and wanted to make sure that everybody who reads this blog knows about this little feature which is commonly confused. Here is his statement and we will start our story with Matthew’s own statement: “Users often confuse CTE with Temp Table but technically they both are different, CTE are like Views and they can be updated just like views.“ Very true statement from Matthew. I totally agree with what he is saying. Just like him, I have enough, time came across a situation when developers think CTE is like temp table. When you update temp table, it remains in the scope of the temp table and it does not propagate it to the table based on which temp table is built. However, this is not the case when it is about CTE, when you update CTE, it updates underlying table just like view does. Here is the working example of the same built by Matthew to illustrate this behavior. Check the value in the base table first. USE AdventureWorks2012; -- Check - The value in the base table is updated SELECT Color FROM [Production].[Product] WHERE ProductNumber = 'CA-6738'; Now let us build CTE with the same data. ;WITH CTEUpd(ProductID, Name, ProductNumber, Color) AS( SELECT ProductID, Name, ProductNumber, Color FROM [Production].[Product] WHERE ProductNumber = 'CA-6738') Now let us update CTE with following code. -- Update CTE UPDATE CTEUpd SET Color = 'Rainbow'; Now let us check the BASE table based on which the CTE was built. -- Check - The value in the base table is updated SELECT Color FROM [Production].[Product] WHERE ProductNumber = 'CA-6738'; That’s it! You can update CTE and it will update the base table. Here is the script which you should execute all together. USE AdventureWorks2012; -- Check - The value in the base table is updated SELECT Color FROM [Production].[Product] WHERE ProductNumber = 'CA-6738'; -- Build CTE ;WITH CTEUpd(ProductID, Name, ProductNumber, Color) AS( SELECT ProductID, Name, ProductNumber, Color FROM [Production].[Product] WHERE ProductNumber = 'CA-6738') -- Update CTE UPDATE CTEUpd SET Color = 'Rainbow'; -- Check - The value in the base table is updated SELECT Color FROM [Production].[Product] WHERE ProductNumber = 'CA-6738'; If you are aware of such scenario, do let me know and I will post this on my blog with due credit to you.

• Dependency injection with n-tier Entity Framework solution

  - by Matthew

  I am currently designing an n-tier solution which is using Entity Framework 5 (.net 4) as its data access strategy, but am concerned about how to incorporate dependency injection to make it testable / flexible. My current solution layout is as follows (my solution is called Alcatraz): Alcatraz.WebUI: An asp.net webform project, the front end user interface, references projects Alcatraz.Business and Alcatraz.Data.Models. Alcatraz.Business: A class library project, contains the business logic, references projects Alcatraz.Data.Access, Alcatraz.Data.Models Alcatraz.Data.Access: A class library project, houses AlcatrazModel.edmx and AlcatrazEntities DbContext, references projects Alcatraz.Data.Models. Alcatraz.Data.Models: A class library project, contains POCOs for the Alcatraz model, no references. My vision for how this solution would work is the web-ui would instantiate a repository within the business library, this repository would have a dependency (through the constructor) of a connection string (not an AlcatrazEntities instance). The web-ui would know the database connection strings, but not that it was an entity framework connection string. In the Business project: public class InmateRepository : IInmateRepository { private string _connectionString; public InmateRepository(string connectionString) { if (connectionString == null) { throw new ArgumentNullException("connectionString"); } EntityConnectionStringBuilder connectionBuilder = new EntityConnectionStringBuilder(); connectionBuilder.Metadata = "res://*/AlcatrazModel.csdl|res://*/AlcatrazModel.ssdl|res://*/AlcatrazModel.msl"; connectionBuilder.Provider = "System.Data.SqlClient"; connectionBuilder.ProviderConnectionString = connectionString; _connectionString = connectionBuilder.ToString(); } public IQueryable<Inmate> GetAllInmates() { AlcatrazEntities ents = new AlcatrazEntities(_connectionString); return ents.Inmates; } } In the Web UI: IInmateRepository inmateRepo = new InmateRepository(@"data source=MATTHEW-PC\SQLEXPRESS;initial catalog=Alcatraz;integrated security=True;"); List<Inmate> deathRowInmates = inmateRepo.GetAllInmates().Where(i => i.OnDeathRow).ToList(); I have a few related questions about this design. 1) Does this design even make sense in terms of Entity Frameworks capabilities? I heard that Entity framework uses the Unit-of-work pattern already, am I just adding another layer of abstract unnecessarily? 2) I don't want my web-ui to directly communicate with Entity Framework (or even reference it for that matter), I want all database access to go through the business layer as in the future I will have multiple projects using the same business layer (web service, windows application, etc.) and I want to have it easy to maintain / update by having the business logic in one central area. Is this an appropriate way to achieve this? 3) Should the Business layer even contain repositories, or should that be contained within the Access layer? If where they are is alright, is passing a connection string a good dependency to assume? Thanks for taking the time to read!

• Add Your Own Domain to Your WordPress.com Blog

  - by Matthew Guay

  Now that you’ve got a nice blog on WordPress.com, why not get your own domain to brand your site?  Here’s how you can easily register a new domain or move your existing domain to your WordPress site. By default, your free WordPress address is yourblog’sname.wordpress.com.  But whether this is a personal or a company blog, it can be nice to have your own domain to really brand your site and make it your own.  Or, if you already have another website and want to use WordPress as a blog for it, you could even add blog.yoursite.com or any other subdomain. Adding a domain to your WordPress.com is a paid upgrade; registering and mapping a new domain to your account costs $14.97 a year, while mapping a domain you already own to your WordPress blog costs $9.97 a year. Getting Started Login to your blog’s dashboard, click the arrow beside Upgrades in the sidebar, and select Domains. Enter the domain or subdomain you want to add to your site in the text box, and click Add domain to blog.   If you entered a new domain you want to register, WordPress will make sure the domain is available and then present you a registration form to register the domain.  Enter your information, and then click Register Domain.   Or, if you enter a domain that’s already registered, you will see the following prompt. If this domain is a domain you own, you can map it to WordPress.com.  Login to your domain registrar account and switch your nameserver to: NS1.WORDPRESS.COM NS2.WORDPRESS.COM NS3.WORDPRESS.COM Your DNS settings page for your domain may be different, depending on your registrar.  Here’s how our domain settings looked. Alternately, if you’re wanting to map a subdomain, such as blog.yoursite.com to your WordPress blog, create the following CNAME record on your domain register.  You may have to contact your domain registrar’s support to do this.  Substitute your subdomain, domain, and blog name when creating the record. subdomain.yourdomain.com. IN CNAME yourblog.wordpress.com. Once your settings are correct, click Try Again in your WordPress dashboard.  The DNS settings may take a while to update, but once WordPress can tell your DNS settings point to it, you will see the following confirmation screen.  Click Map Domain to add this domain to your WordPress blog. Now you’re ready to pay for your domain mapping or registration.  Depending on your purchase, the information and price shown may be different.  Here we’re mapping a domain we already have registered, so it costs $9.97.  Select your method of payment, enter your payment information or signin with your Paypal account, and continue as usual. Once your purchase is finished, you’ll be returned to the Domains page on WordPress.  Try going to your new domain, and make sure it opens your blog.  If it works, then click the bullet beside the new domain, and click Update Primary Domain.  Now, when people visit your WordPress site, they’ll see your new domain in the address bar.  You can still access your blog from your old yourname.wordpress.com address, but it will redirect to you new domain. Conclusion Having a personalized domain is a great way to make your blog more professional, while still taking advantage of the ease of use that WordPress.com offers.  And, if you have your own domain, you can easily move to your site traffic to a different hosting provider in the future if you need to.  The process is slightly complicated, but for $15/year we found this one of the best upgrades you could do to your WordPress.com blog.

• Fastest light-weight image viewer over forwarded x11 session (linux)

  - by Matthew

  I have a slow network connection over which I'm forwarding x11 over ssh. I want to view images on the remote host (Ubuntu) quickly and efficiently. I'm looking for an image viewer that will take into account the image viewer window's resolution and downsize the image before sending it over the network, instead of sending the full size image. The images I want to view will be around 5MB and I only need to be able to browse through tiny thumbnails of the images to identify the image I'm looking for. It is not necessary to be able to see more than one image at a time. Highest speed over slow network connection is the priority. Thanks! Matthew EDIT: It's possible that the way x11 forwarding works, only the image at the display resolution will be transferred anyway. If that's true, please confirm and the question still stands for which image viewer will be the fastest over a slow connection

• gnu screen - mouse does not work in nested screen session

  - by Matthew

  I started a screen session inside another screen session, both on my local machine. This is using cygwin, but I don't think it matters. I have tried via ssh to a real unix machine but the behaviour is the same. Mouse works great in the first screen session, I'm able to open vim with :set mouse=a and I can click to move the cursor or switch tabs, and the mouse wheel scrolls. But in the nested session it does not work, mouse is only useful for selecting terminal text that gets put in the clipboard, but is not able to interact with vim. I want this to work because I usually work with a local screen session, then ssh to a remote server and have a remote screen session running too (hence the nesting) and I like to scroll swiftly in vim by using the mouse wheel. Can anyone tell me why the mouse works in the first layer of screen but not in the second, nested screen session, and how I can make it work? Thanks in advance, Matthew

• How do I correctly set up Application Request Routing in IIS7 to route SSL requests?

  - by Matthew Belk

  I have a 3-node web farm being managed by IIS7 and Application Request Routing. I have a folder hierarchy in my web app that needs to be secured via SSL. What is the best practice for getting ARR to correctly route these SSL requests? I have installed the same certificate on all web farm servers and the server running ARR. I have tried enabling and disabling the SSL Off-loading feature Thanks, Matthew

• Wait for function to finish before starting again.

  - by Matthew Brown

  Good Morning, I am trying to call the same function everytime the user presses a button. Here is what happens at the moment.. User clicks button - Calls function - function takes 1000ms+ to finish (due to animation with jQuery and AJAX calls) What I want to happen is every time the user presses the button it adds the function to the queue, waits for the previous call to finish, and then starts.. Is this possible? Sorry if my explanation is a bit confusing.. Thanks Matthew

• Apache2 Enabling Includes module causes svn access to quit working

  - by Matthew Talbert

  I have dav_svn installed to provide http access to my svn repos. The url is directly under root, eg mywebsite.com/svn/individual-repo. This setup has been working great for some time. Now, I need SSI (server-side includes) for a project, so I enabled this module with a2enmod include. Now, tortoisesvn can't access the repo; it always returns a 301 permanent redirect. Some playing with it reveals I can access it in a browser if I'm sure to include the trailing / but it still doesn't work in TortoiseSVN. I've looked at all of the faq's for this problem with TortoiseSVN and apache, and none of them seem to apply to my problem. Anyone have any insight into this problem? I'm running Ubuntu 9.10 with Apache 2.2.12. The only change I've made to my configuration is to enable the includes mod. Here's my dav_svn conf: <Location /svn> DAV svn SVNParentPath /home/matthew/svn AuthType Basic AuthName "Subversion repository" AuthUserFile /etc/subversion/passwd Require valid-user </Location> and here's the relevant part of my virtual host conf: <Location /svn> SetHandler None Order allow,deny Allow from all </Location> Edit: OK, I've discovered that the real conflict is between the include module and basic authentication. That is, if I disable the include module, browse to the subversion repo, enter my user/pass for the basic authentication, I can browse it just fine. It even continues to work after I re-enable the include module. However, if I browse with another browser where I'm not already authenticated, then it no longer works.

• Crazy problem with Nginx, PHP5-FPM on Ubuntu

  - by Emmanuel

  I've been trying to get a domain from shared hosting to my new VPS. Everything was working just 100% fine, and then all of a sudden rewrites stopped working, pictures that should work started returning 404s. I've got no idea why, but for some reason on my site: http://www.onlythebible.com/ only the home page works, all the other pages depend on rewrites which were working perfectly fine at one stage, but all of a sudden stopped working. Some of the pictures like this url: http://www.onlythebible.com/bgsPreview/Matthew-8.10.jpg which doesn't use a rewrite throws a 404? I almost certain it was nothing to do with the nginx configuration. I've got suspicions that it could be something to do with php5-fpm? The funny thing is, all of a sudden it started working again. And then an hour or so later it broke again and has now gone back to only displaying the home-page and all of the links (and some of the pictures) are just showing 404s. Does anyone have an idea of what the problem might be? I'm pretty new to the whole Linux VPS thing, but this just seems very strange. *edit Here's a line from the error log which might shed some light on the problem: 2011/02/06 03:04:59 [error] 2873#0: *220 open() "/usr/local/nginx/html/bgsPreview/Matthew-8.10.jpg" failed (2: No such file or directory), client: 114.77.115.211, server: onlythebible.com, request: "GET /bgsPreview/Matthew-8.10.jpg HTTP/1.1", host: "www.onlythebible.com", referrer: "http://www.onlythebible.com/" I wonder why it's trying to find the file in /usr/local/nginx/html instead of the proper root which is /var/www/ etc... Oh, and for some reason it's just started working again... for how long I don't know. Another thing that was a bit weird, is that the pages on my website are pulled from a database. But when I edited the database, the pages didn't change... It's almost like they've been cached or something.

• Where is empathy-log.xsl?

  - by Tom Savage

  Conversation logs saved by Empathy are in XML format. Each one links to a stylesheet "empathy-log.xsl": <?xml-stylesheet type="text/xsl" href="empathy-log.xsl"?> I've trawled my hard drive and the web but cannot find it (there is a empathy-log-manager.xsl but this is different). Does it even exist? If there is no such file I'll create my own but I'd rather use the one provided.

• Bonjour/mDNS Broadcast across subnets

  - by Matthew Savage

  I have just setup a new OSX Server in our office and verified that everything is working fine over our wired network (192.168.126.0/24). The problem that I am having is that our clients (Mac Laptops) are mainly connected via Wireless, which are running on a different subnet (192.168.1.0/24), and the mDNS Broadcast isn't reaching this subnet. The network configuration is somewhat foreign to myself (I don't manage the network in this location, but as of just recently the servers), however I don't believe there is any firewalls or routing rules between the two subnets which might cause the traffic to be rejected. I'm wondering if this is simply the mDNS broadcast not able to broadcast over the two different subnets (I'm still reading up on broadcast to understand it more) or there is something else which I might be able to try.

• OSX Mail.app - how to prevent addresses being automatically added to Address Book

  - by Matthew Savage

  Is there any way to disable the feature where Mail.app on OS X 10.6 will automatically add addresses into the address book when replying to an email from someone not in your address book already? I have looked through the settings and tried to find ways around this on Google but nothing has come up, so I thought it best to ask the genius pool. Cheers!

• SSH Login to an EC2 instance failing with previously working keys...

  - by Matthew Savage

  We recently had an issues where I had rebooted our EC2 instance (Ubuntu x86_64, version 9.10 server) and due to an EC2 issue the instance needed to be stopped and was down for a few days. Now I have been able to bring the instance back online I cannot connect to SSH using the keypair which previously worked. Unfortunately SSH is the only way to get into this server, and while I have another system running in its place there are a number of things I would like to try and retrieve from the machine.

• Can Castle Monorail and ASP.NET MVC coexist in the same project?

  - by Matthew

  I have a large Monorail project that we have decided we are going to move over to ASP.NET MVC. Most of the underlying system will likely be reusable, but the Controllers will of course have to be rewritten, and proabably at least some of the views. It strikes me that a low risk avenue for this is gradually convert well defined sections of the system to MVC, and perhaps as MVCContrib Portable Areas. Does anyone know if there are any non-obvious gotchas that I am likely to run into with this approach? Thanks for your input, Matthew

• Blocking internet poker applications

  - by Matthew Savage

  I 'look after' the wireless internet for a cafe where I live, and we've noticed that there's quite a substantial slow down of internet speeds when certain users are playing internet poker. I've put in filters to block any HTTP traffic referencing gambling and poker etc, however I want to be able to block any applications (i.e. poker clients) which don't use HTTP. I've tried searching around for a list of poker clients and perhaps their ports, but have had no real luck. Does anyone know what these might be?

• Install mSATA SSD on Lenovo A720

  - by Chuck Savage

  I apologize in advance for using tag names in title, it seemed it would be clearer this way I just purchased a Lenovo A720 and they have a more expensive version than what I purchased that has a SSD. I figured to buy the SSD separately and save myself a little money and install it myself. I've taken off the base cover but there doesn't seem to be a place to put the SSD. Here are some pictures - any suggestions? There are places on the web where people have said they've done the installation but not how or with pictures. Edit: On Lenovo forums, someone had done it but doesn't say how - I've replied asking how. Added two more pictures per request:

• Configuring OS X L2TP VPN to use Certificate for IPSEC layer instead of Pre Shared Key

  - by Matthew Savage

  I'm trying to setup a L2TP VPN on an OS X Snow Leopard Server setup, and have had success using a pre-shared key, however I would rather not rely on a simple string, and use a certificate instead. Setting this up on the server side is seemingly easy, you simply select a certificate you have generated from the list, and hit apply, however when I try to use the certificate on the client side it fails. I have exported the certificate into a P12 file, and then transferred to the client, and imported into the login keychain, however when I try to choose the certificate (from Network preferences, clicking Authentication Settings, then selecting Certificate and pressing Select) I am shown the following error: No machine certificates found Certificate authentication cannot be used because your keychain does not contain any suitable certificates. Use Keychain Access to import the certificate into your keychain. If you do not have the certificates required for authentication, contact your network administrator. Unfortunately even when I try to generate a certificate where I override the defaults, ensure the DNS name etc are set properly this doesn't change. When I select Certificate Authentication for the User Auth, and click Select the certificate for the server shows up there, but obviously this isn't where I need it to be available.
