• Using Gradle with an existing Android project

  - by Tom Reznik

  I have an existing Android project with the following structure: - ProjectName -- AndroidManifest.xml -- local.properties -- project.properties -- assets -- libs (containing all jars) -- modules (containing all library projects my project depends on) -- res -- src ---- com/namespace/projectname (all my classes including main activity are here) I haven't been using any specific build system to build my project other than the one provided by default with the Android Studio IDE (though the project was originally created with IntelliJ CE. I would like to use Gradle with the android plugin and do some work on my build process. I have tried several configurations in order to achieve this and have failed to complete a successful build every time. What's the recommended approach in this scenario? should I change my project structure? or is it possible to configure gradle using the existing structure? Any help would be greatly appreciated. Thanks!

• C#: proprietary DLLs requiring access to my assemblies

  - by Craig Johnston

  My solution uses a proprietary assembly, which when debugging the solution throws an Exception saying it can't find an assembly that is meant to be one of the projects in my solution. I cannot add a reference to the proprietary assembly because all I have is the DLL. When I compile everything into a single application directory and run the app it works fine, but I want to debug. Where should assemblies be placed if you want a proprietary assembly in the solution to see them? I assume the issue is that there is no path specified and it is just looking in a default directory of some kind.

• Correctly Applying an Open Source License

  - by Johannes Rudolph

  My question consists of multiple points that are inherently related, I apologize for that. I tried splitting it up a little more, but I would keep repeating myself. What exactly is required to apply an open source license to a code base that is my Intellectual Property? A lot of Open Source projects include a full copy of the license somewhere in a root directory but do also have some sort of file header including a license description, disclaimer and a copyright notice. Is that really necessary or does it depend on the license type? If someone else contributes changes to this file, does he need to be named in the copyright notice too?

• Recursive compilation using gcc

  - by curiousexplorer

  I am using the gcc compiler. My project source tree looks like somewhat like this test$~: tree . . |-- folder | |-- hello.cpp | `-- hello.h `-- main.cpp 1 directory, 3 files test$~: The file main.cpp contains the main() function and all the functions invoked by main.cpp lie in the directory named folder So far in all my little projects I never had to put some source code under a sub-directory. What I am looking for, in short, is some gcc command for recursive compilation in sub-directories and their subdirectories and so on... This command should be invoked from the home directory of the code project.

• Security in API authentication

  - by Carlos

  We are in the process of revamping our server side API, and we need to manage security. Our current model requires that a credentials object (containing user, password, and pin) be included in each method invocation. Our development team, however, has decided that we should have session objects instead (which is fine by me), but the new credentials are just a GUID. This is very different from what I've seen in other APIs in our industry, so I'm a bit concerned about how secure the new model will be. I asked them if they had analyzed both alternatives, and they said they haven't. Does anyone know if there're any clear advantages, disadvantages, risks, etc. of using a set of credentials versus just one element (complex as it may be)? PS: the communication channel would be secure in either case, and it's separate from this particular topic

• design question for transportation agency/workflow system

  - by George2

  Hello everyone, I am designing a transportation agency/workflow system, and it including 3 types of people, customer who requests to transport some stuff, drivers who deliver the stuff, and truck manager who manages transport source/destination truck coordination and communicates/organizes drivers. The system is expected to be a web site, and 3 kinds of people could use the web site to submit request, accept request, monitor status of specific stuff transportation, etc. The web site is more like an open agency or a workflow system. I am wondering whether there are any existing technologies, tools or projects (better to be open source, but not a must) which I could build my application faster based on? I prefer to use .Net technologies, but not a must. thanks in advance, George

• Java: Line appears when using AffineTransform to scale image

  - by Malakim

  Hi, I'm having a problem with image scaling. When I use the following code to scale an image it ends up with a line either at the bottom or on the right side of the image. double scale = 1; if (scaleHeight >= scaleWidth) { scale = scaleWidth; } else { scale = scaleHeight; } AffineTransform af = new AffineTransform(); af.scale(scale, scale); AffineTransformOp operation = new AffineTransformOp(af, AffineTransformOp.TYPE_NEAREST_NEIGHBOR); BufferedImage bufferedThumb = operation.filter(img, null); The original image is here: http://tinyurl.com/yzv6r7h The scaled image: http://tinyurl.com/yk6e8ga Does anyone know why the line appears? Thanks!

• html tag attribute displayed in unicode

  - by user297975

  I have the following code, from which you can see that, I use the same way to create the text in utf-8. The text shown between html tags are shown corrently. But the text shown as html tag attribute are shown in unicode. I'm positive that on the server side(PHP), both texts are treated in the same way and are encoded in utf-8. Why the text as html tag attribute shown in unicode? ?????????????????????? ??

• Can't see or add Website Data Sources in RDLC report in ASP.NET MVC

  - by RobertC

  In the RDLC report, in Design view in Visual Studio 2008, we don't see anything in the Website Data Sources tab and the button to Add New Data Source is grayed out. Only the Refresh button is enabled, and clicking it doesn't do anything. Our business logic layer returns Lists of business objects and the business logic and business object projects are both referenced by the MVC project. This is an MVC app, so there is no App_Code folder. How do we get our business objects to appear in the Website Data Sources list so we can drag and drop fields from the object onto our RDLC report?

• Call glutinit in a PHP extension

  - by Yijinsei

  Hi guys, I am developing a php extension that require the use of opengl. I tried to initialize the library with glutinit; it works in CLI environment but when I tried on browser it doesn't seem to execute the code. The code is actually executed on the server side. It is part of a process to extract features from an image, and the server will return a list of closest image to the user. I very new to opengl, so I'm not sure what kind of error is this, does anybody have any knowledge with this?

• Should I really be expected to work more than 40 hours a week just because I am 'salaried developer'

  - by Ryan

  My boss says that I shouldn't be counting hours, but I am only getting paid for a full time job 40 hours per week. I don't get it. I could be using the rest of the hours in my day to run a small side business and get more income. However I have noticed other people just working and working whatever hours to hit the deadline. How is this fair? Of course the argument was 'if you worked more and increased your value then you will get more money'. A friend I regard as one of the smartest people I know (engineered his own sonar system for example) said that you should never work beyond what you are getting paid for. Thoughts?

• Is there a better way than #if DebugMode for logging

  - by Daniel

  I'm making a c++ library thats going to be P/Invoked from c#, so i am unable to breakpoint/debug the c++ side of things. So i decided to add logging so i can see if anything goes wrong and where it happens. I add a #define DebugMode 1 in order to determine if i am to log or not. First of all i'm not very good at c++ but i know enough to get around. So my questions are: Is there a better way than wrapping #if DebugMode #endifs around every Log call? I could simply do that inside the method and just return if logging isn't disabled but won't that mean then all those logging strings will be in the assembly? How can i emulate what printf does with its "..." operator enabling me to pass something like Log("Variable x is {0}", x); Thanks!

• What is the best logging solution for a C# .NET 3.5 project?

  - by Odd

  My team is about to start a new enterprise wide ASP.NET development project, quite possibly the largest undertaken by my department so far and the largest project that I've ever worked on. I'm looking for a good logging solution for the system. Firstly, what logging tools are currently available and widely used? Secondly, for an ASP.NET (probably MVC) enterprise applicaiton, which tool is most appropriate based on your experience? So far I've used Log4net almost exclusively for all my previous projects. It's a fantastic tool, however I would like to see if there is anything I've not used out there before I start a project of this magnitude or if there is any reason I would not want to use Log4net for a project of this size.

• Git: removing selected commits from repository

  - by xk0der

  I would like to remove selected commits from a linear commit tree, so that the commits do not show in the commit log. My commit tree looks something like: R--A--B--C--D--E--HEAD I would like to remove the B and C commits. So that they do not show in the commit log, but changes from A to D should be preserved. Maybe by introducing a single commit, so that B and C become BC and the tree looks like. R--A--BC--D--E--HEAD Or, ideally, after A comes D directly. D' representing changes from A to B, B to C and C to D. R--A--D'--E--HEAD Is this possible? if yes, how? Some notes that might be helpful: This is a fairly new project so has no branches as of now, hence no merges as well. Side note: It's a personal project, so no, I'm not trying to destroy any evidence :)

• Buffer management for socket application best practice

  - by Poni

  Having a Windows IOCP app............ I understand that for async i/o operation (on network) the buffer must remain valid for the duration of the send/read operation. So for each connection I have one buffer for the reading. For sending I use buffers to which I copy the data to be sent. When the sending operation completes I release the buffer so it can be reused. So far it's nice and not of a big issue. What remains unclear is how do you guys do this? Another thing is that even when having things this way, I mean multi-buffers, the receiver side might be flooded (talking from experience) with data. Even setting SO_RCVBUF to 25MB didn't help in my testings. So what should I do? Have a to-be-sent queue?

• Problem with assigning elements of a class array to individual variables in MATLAB

  - by Marc

  This is a bit of a duplicate of this question, this question, and this question, however those solutions don't work, so I'm asking mine. I've got an array of locally defined classes and I'd like to assign it to multiple, individual variables. This pattern doesn't work: %a is 2x1 of MyClass temp = mat2cell(a); [x,y] = temp{:}; %throws: ??? Insufficient number of outputs from right hand side of equal sign to satisfy assignment. Because temp is a single cell, with my 2x1 array in one cell, rather than a 2x1 cell array with one element of each of my original array in one cell. Any ideas?

• Unable to view ChildWindows in Silverlight

  - by Doug Nelson

  So here is the deal. I have created a silverlight dll that contains two ChildWindow dialogs. These dialogs are self contained with a WCF service reference. I want to reuse these dialogs across multiple projects. I have added a reference to the dll in another project. I am able to new up the childWindow, however, I am not able to set the public properties on it and when I call the Show method, nothing is displayed. Not really sure where to start to figure out why this is not working.

• How well does Scala Perform Comapred to Java?

  - by Teja Kantamneni

  The Question actually says it all. The reason behind this question is I am about to start a small side project and want to do it in Scala. I am learning scala for the past one month and now I am comfortable working with it. The scala compiler itself is pretty slow (unless you use fsc). So how well does it perform on JVM? I previously worked on groovy and I had seen sometimes over performed than java. My Question is how well scala perform on JVM compared to Java. I know scala has some very good features(FP, dynamic lang, statically typed...) but end of the day we need the performance...

• Spotlight search with PHP

  - by htf

  Hi. I want to add a spotlight search functionality - search results being displayed with rich contents like thumbnail etc in a drop down menu changing on each keyup event - just like the apple.com search - to a site, having data in MySQL InnoDB tables. The data is spread into separate tables for categories, help pages, blog pages and so on. The search script must take into account just a subset of columns. Since it seems to be a popular demand, I guess there are some PHP search engine projects (preferably open-source and with memcached support), which could be integrated into the existing system on the basis of regular exports of relevant data from the working db/tables. Are there any solutions out there? Which one would you recommend? Or maybe it would be better to implement it the other way around? Thanks

• Folder cleanup with PowerShell

  - by 280Z28

  I'd like to clean up some directories after my script runs by deleting certain folders and files from the current directory if they exist. Originally, I structured the script like this: if (Test-Path Folder1) { Remove-Item -r Folder1 } if (Test-Path Folder2) { Remove-Item -r Folder2 } if (Test-Path File1) { Remove-Item File1 } Now that I have quite a few items listed in this section, I'd like to clean it up. How can I do so? Side note: The items are cleaned up before the script runs, since they are left over from the previous run in case I need to examine them.

• st-ordering library function?

  - by chang

  I'm in the search for an implementation of an ear-decomposition algorithm (http://www.ics.uci.edu/~eppstein/junkyard/euler/ear.html). I examined networkx and didn't find one. Although the algorithm layout is vaguely in my mind, I'd like to see some reference implementation, too. Side problem: First step could be an st-ordering of a graph. Are there any implementations for st-ordering algorithms you know? Thanks for your input. I'd really like to contribute e.g. to networkx by implementing the ear-decomposition algorithm in python.
