• Supporting and testing multiple versions of a software library in a Maven project

  - by Duncan Jones

  My company has several versions of its software in use by our customers at any one time. My job is to write bespoke Java software for the customers based on the version of software they happen to be running. I've created a Java library that performs many of the tasks I regularly require in a normal project. This is a Maven project that I deploy to our local Artifactory and pull down into other Maven projects when required. I can't decide the best way to support the range of software versions used by our customers. Typically, we have about three versions in use at any one time. They are normally backwards compatible with one another, but that cannot be guaranteed. I have considered the following options for managing this issue: Separate editions for each library version I make a separate release of my library for each version of my company software. Using some Maven cunningness I could automatically produce a tested version linked to each of the then-current company software versions. This is feasible, but not without its technical challenges. The advantage is that this would be fairly automatic and my unit tests have definitely executed against the correct software version. However, I would have to keep updating the versions supported and may end up maintaining a large collection of libraries. One supported version, but others tested I support the oldest software version and make a release against that. I then perform tests with the newer software versions to ensure it still works. I could try and make this testing automatic by having some non-deployed Maven projects that import the software library, the associated test JAR and override the company software version used. If those projects build, then the library is compatible. I could ensure these meta-projects are included in our CI server builds. I welcome comments on which approach is better or a suggestion for a different approach entirely. I'm leaning towards the second option.

• Add Multiple Types of Items to the Desktop Context Menu in Windows 7 or 8

  - by Lori Kaufman

  The context menu in Windows provides a convenient place to start programs, access websites, and open folders. There are several ways to add programs to the menu including a registry method and a free tool. We’ve found another free tool, called Right Click Context Menu Adder, that allows you to add more than just programs to the desktop context menu and the folders context menu. It allows you to add folders, web addresses, and files to the menus, as well as programs. Right Click Context Menu Adder is portable and doesn’t need to be installed. To run it, simply extract the .zip file you downloaded (see the link at the end of this article) and double-click on the .exe file.

• Aggregating customer service emails from multiple ecommerce sites for easy handling

  - by nitbuntu

  For one of my main customer help email addresses I use Mozilla Thunderbird with a combination of tags and saved searches. As the number of my e-commerce sites grows from 1 to more, customer service handling gets more tricky. Is there any simple and efficient way of handling emails from the different sites? Perhaps what I'm looking for is a way of aggregating customer service emails from different sites, into one place? Perhaps there's a way of already doing this within Thunderbird or Gmail?

• How to get uncaught PHP errors from fcgi server

  - by jason

  My web hosting company recently replaced suPHP with fcgi on my dedicated server because I needed opcode functionality. Since then I see loads of 500 errors in apache error and php error log is empty. I have no way to figure out whats the root cause. One reason I found out was time out so my hosting company changed FcgidConnectTimeout and FcgidIOTimeout to a value of 200. I believe there are no more timeout errors in my php script. My question is how do I capture PHP error before 500 internal server error page display to user? I am using Centos 5.8 server, WHM 11.34.0 (build 9), PHP 5.3.18 and Apache/2.2.23 (Unix) mod_ssl/2.2.23 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 mod_fcgid/2.3.6

• Multiple X screens without Xinerama

  - by Kalle Elmér

  Is there some way to move Windows between separate X screens in Ubuntu 12.04? With 3 monitors on 2 GPUs, using Twinview is not an option. Xinerama allows me to drag windows between all monitors, but it also means that I lose all hardware acceleration. I don't expect to be able to drag windows between the screens and have them occupy two monitors simultaneously, but there must be some way to transfer a program while it is running. At the moment, I don't even know how to select which monitor it will use when launched. Any pointers?

• Centralizing a resource file among multiple projects in one solution (C#/WPF)

  - by MarkPearl

  One of the challenges one faces when doing multi language support in WPF is when one has several projects in one solution (i.e. a business layer & ui layer) and you want multi language support. Typically each solution would have a resource file – meaning if you have 3 projects in a solution you will have 3 resource files.   For me this isn’t an ideal solution, as you normally want to send the resource files to a translator and the more resource files you have, the more fragmented the dictionary will be and the more complicated it will be for the translator. This can easily be overcome by creating a single project that just holds your translation resources and then exposing it to the other projects as a reference as explained in the following steps. Step 1 Step 1 -  Add a class library to your solution that will contain just the resource files. Your solution will now have an additional project as illustrated below. Step 2 Reference this project to the other projects. Step 3 Move all the resources from the other resource files to the translation projects resource file. Step 4 Set the translations projects resource files access modifier to public. Step 5 Reference all other projects to use the translation resource file instead of their local resource file. To do this in xaml you would need to expose the project as a namespace at the top of the xaml file… note that the example below is for a project called MaxCutLanguages – you need to put the correct project name in its place.   xmlns:MaxCutLanguages="clr-namespace:MaxCutLanguages;assembly=MaxCutLanguages"   And then in the actual xaml you need to replace any text with a reference to the resource file. <TextBlock Text="{x:Static MaxCutLanguages:Properties.Resources.HelloWorld}"/> End Result You can now delete all the resource files in the other projects as you now have one centralized resource file.

• .htaccess file to implement multiple redirects

  - by RobMorta

  I have a dynamic site and from .htaccess file creating clean URLs: RewriteCond %{REQUEST_URI} !(\.png|\.jpg|\.gif|\.jpeg|\.bmp)$ RewriteRule ^([a-zA-Z0-9_\-\+\ ]+)$ flight.php?flights=$1&slug=$1 This code worked fine for me but when I created a new type of page and trying to get clean URLs with the same code i.e.: RewriteCond %{REQUEST_URI} !(\.png|\.jpg|\.gif|\.jpeg|\.bmp)$ RewriteRule ^([a-zA-Z0-9_\-\+\ ]+)$ manual-page.php?url=$1&slug=$1 it's not working and if I comment the previous two lines then its is working fine. Only one code is working at a time. For first I have a URL domain.com/flight.php?flight-san-fransisco-london-flights and I want this being redirect to domain.com/san-fransisco-london-flights & from the second one I have domain.com/manual-page.php?url=my-new-page and I want this being redirect to domain.com/my-new-page. Is these any way to get both working together?

• Multiple objects listening for the same key press

  - by xiaohouzi79

  I want to learn the best way to implement this: I have a hero and an enemy on the screen. Say the hero presses "k" to get out a knife, I want the enemy to react in a certain way. Now, if in my game loop I have a listener for the key press event and I identify a "k" was pressed, the quick and easy way would be to do: // If K pressed // hero.getOoutKnife() // enemy.getAngry() But what is commonly done in more complex games, where say I have 10 types of character on screen and they all need to react in a unique way when the letter "k" is pressed? I can think of a bunch of hacky ways to do this, but would love to know how it should be done properly. I am using C++, but I'm not looking for a code implementation, just some ideas on how it should be done the right way.

• SQL Server stored procedure + set error message from the records of a table

  - by lucky

  Hello, My question is I have a table with the set of records. I am calling a stored procedure for some other purpose. But when ever it finds some duplicate records. It need to return as error message back to php. C1 C2 c3 abc 32 21.03.2010 def 35 04.04.2010 pqr 45 30.03.2010 abc 12 04.05.2010 xyz 56 01.03.2010 ghi 21 06.05.2010 def 47 17.02.2010 klm 93 04.03.2010 xyz 11 01.03.2010 For the above set it need to check for the records that has the same c1. The stored procedure should return as abc,def,xyz are duplicate. I tried something like this. This will not work it has more than 1 set of duplicate records. Please help me to enhance this to solve the purpose. SET @duplicate = (SELECT c1 FROM temp GROUP BY c1 HAVING count(c1) > 1) --Check for duplicate concession Nr. IF(len(@duplicate) > '1') BEGIN SET @error = @error + ' Duplicate C1 Number:- ' + @duplicate SET @errorcount = @errorcount + 1 END As this one type error I am checking for errorcount. IF @errorcount <> '0' BEGIN GOTO E_General_Error END -- If an error occurs, rollback and exit E_General_Error: PRINT 'Error' SET @error = @error IF @@error <> 0 SET @error = 'Database update failed' ROLLBACK TRANSACTION update_database RETURN END Now it is able to return Duplicate c1 number abc. If there are more than 1 problem comes. Thanks in advance!

• Problem with ubuntu 10.10 running from USB drive

  - by Surjya Narayana Padhi

  Hi Geeks, I recently downloaded Ubuntu 10.10 and created an USB drive with that. I started to run the Ubuntu from that USB drive. But I am facing so much problem. I am thinking why its not so much easy like Windows to do all my job in ubuntu. Always I get some error message or to install something. This time I am getting the following errors. I am trying to download and install Aircrack-ng. So used the command sudo apt-get install aircrack-ng. But the installation stops with the following error : update-initramfs: deferring update (trigger activated) cp: cannot stat `/vmlinuz': No such file or directory dpkg: error processing bcmwl-kernel-source (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: initramfs-tools bcmwl-kernel-source E: Sub-process /usr/bin/dpkg returned an error code (1) I don't even have the aptitude command installed till now. Are all these errors because of I am running the ubuntu from USB drive? Is there any simple and easy way to go to Ubuntu Software Center and download all the required essentials at one shot and then Aircrack-ng? I could not find the Aircrack-ng in Ubuntu Software Center Can anybody give me detail steps to solve all my problems above. I am frustrated searching for updates and installations. When something works and something does not work. Can anybody suggest me how I should proceed after installing ubuntu to run on a USB drive. So that I can use the OS like Windows. Like software download,wireless driver, sound, video, documents, C:, D: all things should be there. Please somebody help.

• Learning by doing (and programming by trial and error)

  - by AlexBottoni

  How do you learn a new platform/toolkit while producing working code and keeping your codebase clean? When I know what I can do with the underlying platform and toolkit, I usually do this: I create a new branch (with GIT, in my case) I write a few unit tests (with JUnit, for example) I write my code until it passes my tests So far, so good. The problem is that very often I do not know what I can do with the toolkit because it is brand new to me. I work as a consulant so I cannot have my preferred language/platform/toolkit. I have to cope with whatever the customer uses for the task at hand. Most often, I have to deal (often in a hurry) with a large toolkit that I know very little so I'm forced to "learn by doing" (actually, programming by "trial and error") and this makes me anxious. Please note that, at some point in the learning process, usually I already have: read one or more five-stars books followed one or more web tutorials (writing working code a line at a time) created a couple of small experimental projects with my IDE (IntelliJ IDEA, at the moment. I use Eclipse, Netbeans and others, as well.) Despite all my efforts, at this point usually I can just have a coarse understanding of the platform/toolkit I have to use. I cannot yet grasp each and every detail. This means that each and every new feature that involves some data preparation and some non-trivial algorithm is a pain to implement and requires a lot of trial-and-error. Unfortunately, working by trial-and-error is neither safe nor easy. Actually, this is the phase that makes me most anxious: experimenting with a new toolkit while producing working code and keeping my codebase clean. Usually, at this stage I cannot use the Eclipse Scrapbook because the code I have to write is already too large and complex for this small tool. In the same way, I cannot use any more an indipendent small project for my experiments because I need to try the new code in place. I can just write my code in place and rely on GIT for a safe bail-out. This makes me anxious because this kind of intertwined, half-ripe code can rapidly become incredibly hard to manage. How do you face this phase of the development process? How do you learn-by-doing without making a mess of your codebase? Any tips&tricks, best practice or something like that?
