• When to choose LAMP over ASP.NET?

  - by Carlo

  Hello. A friend wants to start a dating website, she wants me to help her. We still haven't discussed on what platform it'll be developed, but I'm thinking she'll suggest LAMP to save a buck (which is one reason already to chose over ASP.NET already). If the dating website does well, it'll potentially hold a large amount of data (I'm not sure if this would be another reason to consider either ASP.NET or LAMP). Anyway, I ask this from an ASP.NET developer point of view. I have very little, almost null experience with LAMP, and I don't like it very much either, so if she decides to go with PHP odds are I won't help her. So what would be some good points to bring up when deciding which platform to develop on? Please be objective, I don't want this to be argumentative or anything, try to stick to facts, not opinions alone. Thanks!

• linux display drivers

  - by salman

  I've run into a major display problem on newly installed fedora 11, on my 6 years old pc which runs a pentium4 2.4 GHz processor, 1 gb ddr ram, intel 845 motherboard with integrated graphics card. When i open an image or play a video, my complete screen turns garbled. I simply cannot make out whats on my screen. With difficulty i have to close the image/video window and move around the folder window to clean the screen image. Is it because of my display drivers? How can i fix it? I also ran into mp3 plugins and flash issues which i was able to resovle. I'm new to linux, the sole purpose of isntalling it on my old pc was to learn linux but this display problem is frustrating me. Thanks, Salman

• Example code of libssh2 being used for port forwarding

  - by flxkid

  I'm looking for an example of how to use libssh2 to setup ssh port forwarding. I've looked at the API, but there is very little in the way of documentation in the area of port forwarding. For instance, using PuTTY plink, There is the remote port to listen on, but also the local port that traffic should be sent to. Is it the developers responsibility to do this part? Can an example be developed of this? Also, for the opposite, where a remote port is brought to a local port, do I use libssh2_channel_direct_tcpip_ex? What about an example of this? I really need to do this exact thing on a project right now. How hard would it be to develop a couple of samples of this? I'm willing to put up a bounty if need be to get a couple of working examples of this.

• jQuery change selected option's background on change of selected item

  - by Scott B

  I have a routine that dynamically changes a select list's "selected" option when the corresponding image from a carousel widget is clicked (it's a wordpress template selector). I'd just like to add a flash of background color, then fade to white, to give the user a visual cue that they've just changed the value of the template chooser select list. I've attempted at it below to assign the className "mySelectedOption" to the selected option, but its not working. I'm sure there is perhaps a better way to get the visual cue I'm looking for, (since the css change is static and wont fade back to white background) $('#carousel ul li').click(function(e) { var myOption = $(this).children('img').attr('title'); $("#myTheme option[value='"+myOption+"']").attr('selected', 'selected'); $("#myTheme :selected]").attr('className', 'mySelectedOption'); });

• Mercurial in Windows doesn't see .hgignore - why?

  - by AP257

  Windows fails to pick up my .hgignore file. I'm running Mercurial from the command line, and "hg status" shows lots of files in the ignored directories. The .hgignore file looks like this (there's no whitespace at the start of the file, or at the start of each line). I've put it in the root directory of the repository. \.pyc$ \.pyo$ \.DS_Store \.Python \.installed.cfg ^bin$ ^build$ ^develop-eggs$ ^eggs$ ^include$ ^lib$ ^parts$ ^pip-log.txt$ ^web/localsettings.py$ I've tried saving the file in ANSI and UTF-8, and it doesn't seem to make a difference. I know the file is working OK on Linux, is there anything different about the paths in Windows?

• Compiling .NET component that uses a non specific required version of a 3rd Party Vendor component

  - by Dan

  If someone were to develop a .NET component that relied on non specific versions of a vendor DLL - let's say it worked with My3rdPartyComponent.dll which is a .NET assembly, but it didn't matter which version. Some instances of classes found in this component would need to be passed into my component. Developers would reference my component dll but not have access to the source code. Basically, I want to be able to require the user to pass in an instance of 3rdPartyComponent.MyClass to my component functions but I do not care if it's version 1.1, 2.2, 2.23.980, etc of the 3rd party dll. Is there a way to do this while still typing the parameter I want to be passed in to my component? I don't want to use Object as the reference. In my component project I could specify SpecificVersion=True on the assembly reference. Will this solve my problem or will there be other 'dll hell' issues to deal with that I am not seeing?

• Finding distance travelled by robot using Optical Flow

  - by user280454

  Hi, I'm working on a project right now in which we are developing an autonomous robot. I have to basically find out the distance travelled by the robot between any 2 intervals. I'm using OpenCV, and using the Optical Flow functions of OpenCV, I'm able to find out the velocity/distance of each pixel in 2 different images. Using this information, I want to be able to find out the distance travelled by the robot in the interval between those 2 images. I thought of a way in which we could develop an input output mapping between the distance travelled by pixels and the distance travelled by the bot (using some tests). In this way, using neural networks, we would be able to find the relationship. However, the optical flow would depend on the distance of the camera from the pixel, which would cause problems. Is there any way to solve this problem?

• Best way to implement a Rest API with PHP on Wamp web server

  - by DomingoSL

  Hello, i own a web server running windows (WAMP). I want to know the best way to implement a Rest API (a very simple one) in order to let a user do something. Diagram flow: I have programming skills, in fact, i developed some time ago a web server in VB6 who process the querys and when it find the command (http:/serverIP/webform.php?cmd=run&item=any) it do something, but know i really want to develop a solution using the WAMP server. Some people consider the solution of executing a exe when a command is detected a bad solution for security issues, but this specific proyect i have is for the use of only some people (trusted people) who dont have intentions of hacking the server. So, what do you think? Remember: Its not a public API, its for some people and some programs who will use the API Its a very simple one, only one command using POST or GET. Thanks

• Execute an autocommand only once

  - by Andrej M.

  I have an issue with using GVim on Windows. I have set up the following in my .vimrc: if has("gui_running") autocmd VIMEnter * :source C:/session.vim endif Unfortunately this creates a problem. If I'm a the top of the file and try to move up a line (k), the screen flashes. If I hold the key for just a second it will flash a few dozen times, it is really nasty too look at. I've tried using GUIEnter instead but I got the same results. The docs mention that I can fire an autocommand only once, but I couldn't figure out the exact syntax. Care to help?

• Measuring Programmers' Productivity. Bad, good or invasive?

  - by Fraga

  A client needs my company to develop an app that will be able to measure the programmer productivity, by getting information from VS, IE, SSMS, profiler and VMware. For example: Lines, Methods, Classes (Added, Deleted, Modified) How many time spent in certain file, class, method, specific task, etc. How many time in different stages of the development cycle (Design, Coding, Debugging, Compiling, Testing) Real lines of code. Etc They told me they want to implement PSP. Would you resign if a company wants to measure this way? OR Would you install this kind of software for self improvement?

• Passing data between states PHP

  - by esryl

  So I am using Limonade PHP which has a RESTful design which emulates PUT, POST, DELETE routes for create, update, delete. I am trying to develop some form validation which is going well. The major problem I am facing though is how to return my filtered data (which has failed validation) back to repopulate the create or edit form. How would this be done? I currently have for creating a page: /admin/page/new -> GET function /admin/page -> POST function + validate + pass, update db + fail, add errors to flash, redirect to /admin/page/mew It all falls down as I do not know how to populate the /admin/page/new with the invalid, but filtered data.

• Is it possible to run a MIDP application under Android

  - by SteveM

  The Google Market offers an application purporting to run J2ME MIDP applications on the Nexus One. I have tried this application but it only appears to run MIDP applications that are downloaded from particular web sites; it does not seem capable of picking up a MIDP application that is stored on the SD card in the phone. I have suggested to the developers that they might like to add such functionality, but they have not been particularly responsive to my messages. So I would like to build my own MIDP runner for Android and would like to see if I can find a pointer as to where to start, or even whether this is possible. The MIDP application in question was supplied on CD along with a security camera system and permits remote viewing and remote control over the security system. Clearly it wasn't built with the Android platform in mind. However, if it is possible somehow to run MIDP applications on Android (perhaps by creating some kind of sandbox environment for example) then I'd be quite keen to develop it.

• Recording Audio through RTMP/Rails

  - by Lowgain

  I am in the process of building a rails/flex application which requires audio to be recorded and then stored in our amazon s3 account. I have found no alternative to using some form of RTMP server for recording audio through flash, but our hosting environment will not allow us to install anything like FMS, Red5, etc. Is there any existing Ruby/Rails RTMP solution that will allow audio recording? If not, is it possible for Rails to at least intercept the RTMP stream and then I can hope to reference red5 or something for parsing the data (long shot, I know)? The other alternative I can think of is hosting a red5 server on another host and communicating with our rails app once the saving/uploading is done, which is not preferred. Am I going to have any luck here?

• Ruby Actions: How to avoid a bunch of returns to halt execution?

  - by Alexandre

  How can I DRY the code below? Do I have to setup a bunch of ELSEs ? I usually find the "if this is met, stop", "if this is met, stop", rather than a bunch of nested ifs. I discovered that redirect_to and render don't stop the action execution... def payment_confirmed confirm_payment do |confirmation| @purchase = Purchase.find(confirmation.order_id) unless @purchase.products_match_order_products?(confirmation.products) # TODO notify the buyer of problems return end if confirmation.status == :completed @purchase.paid! # TODO notify the user of completed purchase redirect_to purchase_path(@purchase) else # TODO notify the user somehow that thigns are pending end return end unless session[:last_purchase_id] flash[:notice] = 'Unable to identify purchase from session data.' redirect_to user_path(current_user) return end @purchase = Purchase.find(session[:last_purchase_id]) if @purchase.paid? redirect_to purchase_path(@purchase) return end # going to show message about pending payment end

• how to get an SDP record for bluetooth service??

  - by user302798

  Hi I'm new to both winsock and bluetooth programming. I need to develop a bluetooth service to run on a pc. Looking at the MSDN library they say to use WSASetService(http://msdn.microsoft.com/en-us/library/aa362921%28VS.85%29.aspx) function to publish a service. The problem is that the WSAQUERYSET(http://msdn.microsoft.com/en-us/library/aa362920%28VS.85%29.aspx) structure, that has to be passed to WSASetService, needs a binary SDP record and i don't know how to get it. In the Windows embedded section of the MSDN library they describe a procedure to obtain an SDP record using Bthnscreate. I installed Windows CE 6 to use this tool but i can't find it in the install directory nor in the entire system. How can i get an SDP record? Thanks!

• How can I create a MethodInfo from an Action delegate

  - by Michael Meadows

  I am trying to develop an NUnit addin that dynamically adds test methods to a suite from an object that contains a list of Action delegates. The problem is that NUnit appears to be leaning heavily on reflection to get the job done. Consequently, it looks like there's no simple way to add my Actions directly to the suite. I must, instead, add MethodInfo objects. This would normally work, but the Action delegates are anonymous, so I would have to build the types and methods to accomplish this. I need to find an easier way to do this, without resorting to using Emit. Does anyone know how to easily create MethodInfo instances from Action delegates?

• Real winforms/wpf projects which use MVC, MVP, MVVM

  - by Belousov Pavel

  Hello everybody, I have looked some videos and read some articles about MVC, MVP, MVVM. I think, that I understood basic principles and differences. But it seems to me that samples in articles and videos are very easy. I think that it's easy to learn how to apply these patterns when you can look on some projects. So I'd like to look on real projects(Winforms/WPF), which use MVC, MVP or MVVM. Could you provide me links to sources of such projects? (If it is open source) It will be great if projects will have unit tests for Controller/Presenter/ViewModel, because it's one of my problem when I develop applications. Thanks in advance.

• Blackberry development on scripting language ?

  - by zvr

  From what I've seen, the preferred way to develop Blackberry applications is Java. Is this the only way? I'm dreaming of a rapid application environment where you can create GUIs (using the Blackberry UI components). Something like a port of Tcl/Tk on Blackberry... or Python/Tkinter... or something new, but similar. Does something like that exist ? (I doubt it) Can something like that exist ? (i.e., given the money, is it feasible/reasonable/...)

• ATL OR C# for windows shell/namespace extenssion?

  - by _Avishay_

  Hi, i have a question, after allot of hours in googling and reading articles, i understood that namespace extenssion in windows is quite tricky (In C++ at least), now i've also seen its possible to do so in C# , but microsft does'nt officaly confirms using .net for namespace extensions... though i have seen very nice commercial Namespace Extenssion framework , but none is free.... so to my question :) , i want to develop my own Namespace Extenssion ,i have C++/C# knwoledge and basic COM/ATL , but if it can be done i prefer c#, so does c# inteop can fully do the work without too many tricks ? or one shall go diving in the ATL to create the neccessary COM objects... and another question , can i program to Windows O/S with C# anything that can be done in C++/ATL/MFC ? thanks!

• DBMS for POS software

  - by Andrew Smith

  Hello, I want to develop a POS application in .NET (C#) that would be used to rent items. I have a good idea of what will be done and the famous question that I have is about the DBMS that I should use. I would like to use MySQL database. The question is: If some places use only one computer (no network, no internet connection), can I use a MySQL database in local? Do I need to install MySQL server on all thoses computers to be able to use such a database? I know SQLite but I'm not sure if the limitations can cause problems in the future... I also looked at SQLServer Express versions. (I must consider that other point of sales are using multiple computers and more transactions so there I can't put sqlexpress or sqlite) So can anybody suggest me what I should do in that situation? Thanks
