  • 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.

  • .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?

  • 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.

  • 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?

  • Will having multiple domains improve my seo?

    - by Anonymous12345
    Lets say I have a domain already, for example www.automobile4u.com (not mine), with a website fully running and all. The title of my "Website" says: <title>Used cars - buy and sell your used cars here</title> Also, lets say I have fully SEO the website so when people searching for the term buy used cars, I end up on the second or first page. Now, I want to end up higher, so I go to the google adwords page where you can check how many searches are made on specific terms. Lets say the term "used cars" has 20 million searches each month. Here comes the question, could I just go and buy that domain with the search terms adress, in this case www.usedcars.com and make a redirect to my original page, and this way when people search for "used cars", my newly bought domain name comes up redirecting people to my original website (www.automobile4u.com)? The reason I believe this benefits me is because it seems search engines first of all check website adresses matching the search, so the query "used cars" would automatically bring www.usedcars.com to the first result right? What are the downsides for this? I already know about google spiders not liking redirects, but there are many methods of redirecting... Is this a good idea generally?

  • Good, simple reasons for having multiple environments

    - by smp7d
    Throughout my career I had worked at companies that had a collection of different environments for different purposes. We always had more or less our desktop environment, a test environment, a QA environment, a staging environment and a production environment. This went for both servers/applications and any data sources we were using. When I started at my current company I found that 90% of the apps were either developed on a desktop environment against production data sources or developed directly on the production server depending on the platform. I wasn't fazed because I was hired in part to make changes to improve the way the development team functioned, which was clear from my interview process. We slowly started to turn the philosophy and pretty soon, most of the apps could be run in either a desktop, test or production environment. Not too long after that staging came around as well. Now most of our developers see the benefit of this methodology and defend it vigilantly. However, we have a number of legacy apps that never got migrated. We also have a number of legacy programmers who think of this as a waste of time. Unfortunately, we got lip service but never full buy-in from management. We got what we thought was a commitment to invest substantially in this about a year ago, but nothing materialized despite the considerable planning that we put into it. Now we are finding that we need more and more environments. We need help from the server/network administration teams for setup and we need participation from the business stakeholders to support the release cycle. We are at a place now where a project can function what I consider "normally" only if you have the right people on the project and the time to set up the proper environments. I'd love to present a complete argument, but management really has no time and interest in hearing me out until there is a critical issue. I can't really articulate the benefits simply as it always just seemed second nature to me. I was wondering if there are any good, simple, irrefutable reasons for the separation of environments that would get managers with no development experience to get behind this idea. Are there any good resources/literature on the topic?

  • 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.

  • 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.

  • Triple (3) Monitors under Linux

    - by widgisoft
    I have a 3 monitor setup (each 1680x1050) via an Nvidia NVS440 (2 GPUs, 2 outputs per GPU totalling 4 outputs); this works fine under Windows XP,7 but caused considerable headaches under Linux (Ubuntu 9.04). I had previously used an XFX 9600GT and the onboard XFX 9300GS to produce the same result but the card was noisy and power hungry and I was hoping that there was some magical switch in the NVS4400 that got rid of this annoying problem - turns out the NVS440 is just 2 cards on one physical PCB :-p (I searched the net high and low for people using this card under Linux but found nothing, if anything the card uses less power and is fan less so I was to benefit from it either way) Anyway, using either set up there were 5 solutions available: Have 3 separate X instances, all un joined Have 3 separate X instances, adjoined by Xinerama Have 2 separate X instances - One using twin-view, both adjoined by Xinerama Have 2 separate X instances - One using twin-view but no Xinerama Have a single Twin-view setup and leave the 3rd screen unplugged :-p The 4rd option, using 2 separate X instances and twinview (but no xinerama) was the best balance in terms of performance and usability but caused 2 really annoying issues You couldn't control (without altering the shortcuts) which screen an application opened onto - and once it was opened you couldn't move it to another screen without opening up terminal and forcing it to move Nvidia's overriding or falsifying of Xinerama breaks and the 2 screens joined by Twin view behave like a single huge screen causing popups to open in the middle of both screens and maximising of windows stretches to the width of the first 2 screens Firefox can only run one instance as the same user so having multiple firefox windows requires at least 2 users The second option "feels" like the right option, but OpenGL is basically disabled and playing any sort of game or even running anything graphical causes a huge performance drop and instability - even trying to run a basic emulator for gba or gens just causes the system to fall over. It works just enough to stare at your desktop and do nothing but as soon as you start doing some work - opening windows, dragging things around - running multiple copies of firefox it just really feels slow. The last open, only going dual screen works perfectly and everything performs as required, full GPU acceleration - two logical screen spaces - perfect, just make it work across GPUs like windows! :-p Anyway, I know RandR was supposed to pick up the slack when it would introduced GPU objects of sorts to allow multiple GPUs to be stitched together to create one huge desktop at a much deeper layer than Xinerama. I was wondering if this has now been fixed (I noticed X server 1.7 is out) and whether anyone has got it running successfully? Again, my requirements are: One huge desktop to drag any window across Maximising of windows to each screen (as XP does) Running fullscreen apps on the primary screen and disabling the mouse from moving onto the others or on all 3 stretched Finally as a side note; I am aware of the Matrox triple (and dual) head splitter but even the price they go for on eBay is more than I can afford atm, my argument: I shouldn't have to buy extra hardware to get something to work on Linux when it's something that's existed in the windows world for a long time (can you tell I don't get on with X :-p); If I had the cash I'd have bought the latest version of this box already (the new version finally supports large resolutions as the displays I have 1680x1050 each).

  • All in a Day's Work: Unblocking Multiple Downloaded Files with a Single Command

    - by Sam Abraham
    Files downloaded using Internet Explorer retain Internet Zone permission level and hence are “Blocked” by default on Windows 7 machines. Honestly, while an added overhead for developers; I really appreciate this feature as it provides a good protection layer for casual web users. My workaround is to simply unblock the downloaded zip file (if download was a zip file) which, in turn, unblocks the files stored within. Today however, I was left with a situation where I had to “Open” and “Copy” the content rather than “Save” a zip file. That of course left me with a few dozen files I have to manually unblock. A few minutes of internet search lead me to the link below which worked like a charm: 1-Download streams.exe from SystInternals - http://technet.microsoft.com/en-us/sysinternals/bb897440.aspx 2-Go to command prompt (cmd.exe) 3-Navigate to where you have streams.exe installed 4-Use command line switches: streams.exe –s –d “<folder path>” This removed the Internet Zone restrictions from all files under “<folder path>” and its subfolders as well. [Deleted :Zone.Identifier:$DATA] References: http://social.technet.microsoft.com/Forums/en-US/itproxpsp/thread/806f0104-1caa-4a66-b504-7a681d1ccb33/

  • Test-Driven Development with plain C: manage multiple modules

    - by Angelo
    I am new to test-driven development, but I'm loving it. There is, however, a main problem that prevents me from using it effectively. I work for embedded medical applications, plain C, with safety issues. Suppose you have module A that has a function A_function() that I want to test. This function call a function B_function, implemented in module B. I want to decouple the module so, as James Grenning teaches, I create a Mock module B that implements a mock version of B_function. However the day comes when I have to implement module B with the real version of B_function. Of course the two B_function can not live in the same executable, so I don't know how to have a unique "launcher" to test both modules. James Grenning way out is to replace, in module A, the call to B_function with a function pointer that can have the value of the mock or the real function according to the need. However I work in a team, and I can not justify this decision that would make no sense if it were not for the test, and no one asked me explicitly to use test-driven approach. Maybe the only way out is to generate different a executable for each module. Any smarter solution? Thank you

  • Ubuntu multiple issues (blank screen)

    - by Donavon
    Computer Specs I am having difficulties, to get Ubuntu 11.10 to work. For the 11.10 version, if I click install, or if I click try Ubuntu, I only get a blank screen, that just stays there. If I use "nomodeset", it changes to a loading screen and after about 2 minutes it goes back to black screen - however, before it goes black, i get a few errors, like: bad target number, or passwd error mode (something like that). I've also tried (xforcevesa, i915.modeset=0, nomodeset, radeon.modeset=0, i915.modeset=1) I have also tried the alternate installation, which installed fine, however when I boot up, select it from "grub", it goes black. I did manage to install 10.04, however the screen resolution was 800x600 and I couldn't fix it to 16:9 (my resolution). I don't wanna use 10.04, because I would like the new one 11.10, and would like to use it. Any help would be GREATLY appreciated. Thank you

  • ASP.NET MVVM Handling multiple Data Transfer Objects on a single page

    - by meffect
    I have an asp.net mvc "edit" page which allows the user to make edits to the parent entity, and then also "create" child entities on the same page. Note: I'm making these data transfer objects up. public class CustomerViewModel { public int Id { get; set; } public Byte[] Timestamp { get; set; } public string CustomerName { get; set; } public etc.. public CustomerOrderCreateViewModel CustomerOrderCreateViewModel { get; set; } } In my view I have two html form's. One for Customer "edit" Http Posts, and the other for CustomerOrder "create" Http Posts. In the view page, I load the CustomerOrder "create" form in using: <div id="CustomerOrderCreate"> @Html.Partial("Vendor/_CustomerOrderCreatePartial", Model.CustomerOrderCreateViewModel) </div> The CustomerOrder html form action posts to a different controller HttpPost ActionResult than the Customer "edit" Action Result. My concern is this, on the CustomerOrder controller, in the HttpPost ActionResult [HttpPost] public ActionResult Create(CustomerOrderCreateViewModel vm) { if (!ModelState.IsValid) { return [What Do I Return Here] } ...[Persist to database code]... } I don't know what to return if the model state isn't valid. Right now it's not a problem, because jquery unobtrusive validation handles validation on the client. But what if I need more complex validation (ie: the server needs to handle the validation).
