• On what basis would you split donation money among your open source team members without any strife?

  - by Vigneshwaran

  I am a developer of an open source project which is hosted in SourceForge. It started out as a little app then after some releases, it got more and more popular and it started consuming more time and responsibility from me. So I have enabled the donation option in SourceForge. I'm passionate to continue developing it for free but if (ever) any money comes in, how should I split it with my team? Should I split the amount equally among the number of team members? (50-50 as it is two-member team now) Number of classes, commits or any other valuable submissions by team members? Any other idea? What would you do in such situation? Please give your opinions. I hope this question will be useful for others.

• The cost of longer delay between development and QA

  - by Neil N

  At my current position, QA has become a bottleneck. We have had the unfortunate occurence of features being held out of the current build so that QA could finish testing. This means features that are done being developed may not get tested for 2-3 weeks after the developer has already moved on. With dev moving faster thean QA, this time gap is only going to get bigger. I keep flipping through my copy of Code Compelte, looking for a "Hard Data" snippet that shows the cost of fixing defects grows exponentially the longer it exists. Can someone point me to some studies that back up this concept? I am trying to convince the powers that be that the QA bottleneck is a lot more costly than they think.

• How do you track bugs in your personal projects?

  - by bedwyr

  I'm trying to decide if I need to reassess my defect-tracking process for my home-grown projects. For the last several years, I really just track defects using TODO tags in the code, and keeping track of them in a specific view (I use Eclipse, which has a decent tagging system). Unfortunately, I'm starting to wonder if this system is unsustainable. The defects I find are typically associated with a snippet of code I'm working on; bugs which are not immediately understood tend to be forgotten, or ignored. I wrote an application for my wife which has had a severe defect for almost 9 months, and I keep forgetting to fix it. What mechanism do you use to track defects in your personal projects? Do you have a specific system, or a process for prioritizing and managing them?

• design pattern for unit testing?

  - by Maddy.Shik

  I am beginner in developing test cases, and want to follow good patterns for developing test cases rather than following some person or company's specific ideas. Some people don't make test cases and just develop the way their senior have done in their projects. I am facing lot problems like object dependencies (when want to test method which persist A object i have to first persist B object since A is child of B). Please suggest some good books or sites preferably for learning design pattern for unit test cases. Or reference to some good source code or some discussion for Dos and Donts will do wonder. So that i can avoid doing mistakes be learning from experience of others.

• How to properly structure a project in winform?

  - by user850010

  A while ago I started to create a winform application and at that time it was small and I did not give any thought of how to structure the project. Since then I added additional features as I needed and the project folder is getting bigger and bigger and now I think it is time to structure the project in some way, but I am not sure what is the proper way, so I have few questions. How to properly restructure the project folder? At the moment I am thinking of something like this: Create Folder for Forms Create Folder for Utility classes Create Folder for Classes that contain only data What is the naming convention when adding classes? Should I also rename classes so that their functionality can be identified by just looking at their name? For example renaming all forms classes, so that their name ends with Form. Or is this not necessary if special folders for them are created? What to do, so that not all the code for main form ends up in Form1.cs Another problem I encountered is that as the main form is getting more massive with each feature I add, the code file (Form1.cs) is getting really big. I have for example a TabControl and each tab has bunch of controls and all the code ended up in Form1.cs. How to avoid this? Also, Do you know any articles or books that deal with these problems?

• Complete RESTful API debugging/testing tool

  - by vartec

  I'm looking for the most complete tool, preferably portable GUI or browser plugin to test RESTful API. What I need is: GET/POST/DELETE/PUT support multiple file uploads as fields (multipart/form-data) file uploads as body Extra points for: possibility to save multiple configurations and use them to pre-fill parameters OAuth support nice JSON response formatting Currently I'm using 3 tools: Chrome REST Console extension — My favorite, very nicely done. Has OAuth. However the functionality missing for me is sending file as a body of the request; Cannot send multiple files; Firefox Poster add-on — Quite nice, but the functionality it's missing for file as POST fields parameters; Also cannot send multiple files; cURL — can do anything, but it's quite tedious to use it from command line.

• How do you name your projects?

  - by Corey

  Naming is hard. Really, really hard. Even StackExchange is a prime example of this -- remember the huge domain name controversy that occurred when SE sites first started graduating? Anyway, I've got a project I'm working on but I have no idea what to name it! This simple fact has caused production to cease, because I'm at the point where I want to create repositories and database tables, and I don't want to name everything "Untitled project" and have to change potentially hundreds of lines of code in the future. Also, I would like to collaborate with others but it's difficult to be taken seriously if I refer to this as "some project I'm working on." It makes it seem like a new project in its infancy and doesn't garner a lot of interest. Just the simple fact act of having a name will make a huge impact in how it registers in others' minds. How do you guys name your projects? This particular one is a website, so not only do I need to find a good name, I need to find one with an available domain, which is next to impossible these days. How do you brainstorm? Who do you talk to (or not talk to)? Is there an "eureka!" moment when you stumble across something that works?

• Understanding clojure keywords

  - by tjb1982

  I'm taking my first steps with Clojure. Otherwise, I'm somewhat competent with JavaScript, Python, Java, and a little C. I was reading this artical that describes destructuring vectors and maps. E.g. => (def point [0 0]) => (let [[x y] point] => (println "the coordinates are:" x y)) the coordinates are: 0 0 but I'm having a difficult time understanding keywords. At first glance, they seem really simple, as they just evaluate to themselves: => :test :test But they seem to be used is so many different ways and I don't understand how to think about them. E.g., you can also do stuff like this: => (defn full-name [& {first :first last :last}] => (println first last)) => (full-name :first "Tom" :last "Brennan") Tom Brennan nil This doesn't seem intuitive to me. I would have guessed the arguments should have been something more like: (full-name {:first "Tom" :last "Brennan"}) because it looks like in the function definition that you're saying "no required arguments, but a variable number of arguments comes in the form of a single map". But it seems more like you're saying "no required arguments, but a variable number of arguments comes which should be a list of alternating keywords and values... ?" I'm not really sure how to wrap my brain around this. Also, things like this confuse me too: => (def population {:humans 5 :zombies 1000}) => (:zombies population) 1000 => (population :zombies) 1000 How do maps and keywords suddenly become functions? If I could get some clarification on the use of keywords in these two examples, that would be really helpful. Update I've also seen http://stackoverflow.com/questions/3337888/clojure-named-arguments and while the accepted answer is a great demonstration of how to use keywords with destructuring and named arguments, I'm really looking more for understanding how to think about them--why the language is designed this way and how I can best internalize their use.

• Is writing software in the absence of requirements a skill to possess or a situation I should avoid?

  - by Brian Reindel

  I find that some software developers are very adept at this, and often times are praised for their ability to deliver a working concept with abstract requirements. Frankly, this drives me crazy, and I don't like "making it up" as I go. I used to think this was problematic, but I've started to sense a shift, and I'm wondering if I need to adjust my thought (and programming) process when given very little direction. Should I begin to acquire this ability as a skill, or stick to the idea that requirement's gathering and business rules are the first priority?

• Are flag variables an absolute evil?

  - by dukeofgaming

  I remember doing a couple of projects where I totally neglected using flags and ended up with better architecture/code; however, it is a common practice in other projects I work at, and when code grows and flags are added, IMHO code-spaghetti also grows. Would you say there are any cases where using flags is a good practice or even necessary?, or would you agree that using flags in code are... red flags and should be avoided/refactored; me, I just get by with doing functions/methods that check for states in real time instead. Edit: Not talking about compiler flags

• i need ur help [closed]

  - by aisha khan

  Write a program that prompts the user to enter the size of the array, allocate memory using malloc(), ask the user to enter elements of the array and displays if the puzzle is solvable. As part of this program, write a recursive function int Solvable(int start, int squares[]) that takes a starting position of the marker along with the array of squares. The function should return 1 if it is possible to solve the puzzle from the starting configuration and 0 if it is impossible

• Can this word search algorithm be made faster?

  - by Ashwin Singh

  Problem: Find a match of word S in text T Given: S and T are part of spoken and written English. Example: Match 'Math' in 'I love Mathematics' NOTE: Ignore CASES. My algorithm: STEP 1) Convert S, T to char[] STEP 2) for i=0, i < T.length , i++ STEP 3) for j=S.length-1, j>0 , j-- STEP 3 is the magic, instead of going about matching M,A,T,H, this matches M, H, T and finally A. This helps in eliminating a lot of possible partial matches. For example, if I go sequentially like M A as in Boyer Moore's method ... it can match Matter, Mass, Matchstick etc. using M _ _ H will bring down size of partial matches. STEP 4) if S[j]!=T[i] -> break; else if j==i -> PRINT MATCH

• Shortest Common Superstring: find shortest string that contains all given string fragments

  - by occulus

  Given some string fragments, I would like to find the shortest possible single string ("output string") that contains all the fragments. Fragments can overlap each other in the output string. Example: For the string fragments: BCDA AGF ABC The following output string contains all fragments, and was made by naive appending: BCDAAGFABC However this output string is better (shorter), as it employs overlaps: ABCDAGF ^ ABC ^ BCDA ^ AGF I'm looking for algorithms for this problem. It's not absolutely important to find the strictly shortest output string, but the shorter the better. I'm looking for an algorithm better than the obvious naive one that would try appending all permutations of the input fragments and removing overlaps (which would appear to be NP-Complete). I've started work on a solution and it's proving quite interesting; I'd like to see what other people might come up with. I'll add my work-in-progress to this question in a while.

• What are the advantages of programming to under an OS as opposed to bare metal executive?

  - by gby

  Assume you are presented with an embedded system application to program, in C, on a multi-core environment (think a Cavium or Tilera) and need to choose between two environments: Code the application under Linux in SMP mode or code the application under a thin bare metal executive (something like a very minimal RTOS), perhaps with a single core running UP Linux that can serve control tasks. For the purpose of this question, assume that both environment provide the same level of performance guarantees in any measurable aspects of run time performance, including number of meaningful action per second, jitter, latency, real time considerations - the works. (and yes, I realize this is by far not a trivial assumption at all, bare with me). How would you justify going with a Linux SMP based solution rather then a bare metal thin executive solution? The question may seems silly. It certainly seems obvious to me - but I have to convince someone that does not think the same. Could you help make a list of arguments in favor of choosing a real SMP aware OS (Linux) vs. a bare metal executive assuming performance guarantees are NOT an issue? Many thanks

• Difference between bug, defect and flaw

  - by Hossein

  I was reading "Software Security: Building Security In" and in the first chapter I faced with 3 terms: bug, defect and flaw. The author gave a definition for each of them but I couldn't completely understand these. Can someone give me some examples for each term? What is a defect and what is a flaw? I think I know what bug is, a bug is a malfunction of a part of system which produces undesirable result, be it crashing on a wrong input or miscalculating a series of computations. Can someone elaborate more and correct me if I am wrong in this? UPDATE To be more precise in the book I mentioned above, they (the words) are presented in a way to make a distinction, that's why I am asking to know more. In that book there are some examples denoting which sample belongs to what and which category. For example: Buffer overflow is said to be a bug and issues in method overriding (subclassing issues) is being related to flaw category. Again race condition handling issues are considered bugs and Error-handling problems (fails open) are told to be flaws! I want more elaboration on these regards.

• Should a poll framework be closed sourced

  - by samquo

  I was having a chat with a coworker who is working on a polling app and framework. He was asking technical questions and I suggested he open source the application to get more quality opinions from developers who are interested in this problem and are willing to give it heavy though. He has a different point of view which I think is still valid so I want to open this question for discussion here. He says he believes something like a polling framework should not be open sourced because it will reduce its security and validity as people reveal loopholes through which they can cheat. Can't say I completely disagree. I see a somewhat valid point there, but I always believed that solutions by a group of people are almost always better than a solution thought by a single person asking a small number of coworkers, no matter how smart that person is. Again I'm willing to accept that maybe some types of applications are different. Does anyone have an argument in his favor? I'd really like to present your responses to him.

• Seeking solution for printing-reporting .NET

  - by Parhs

  I am developing an application that prints in separate threads in extreme cases about 20-25 pages per minute to various thermal printers. Currently templates for these are XAML xps documents. All printers have graphics drivers that support EMF/GDI printing. So GDI-EMF is done by operating system resulting in slower performance. Sending raw text for printing is another good solution but doesnt work always , because some clients have old chinese thermal printer that nobody support thus impossible to change codepage / emulation. So it doesnt work always. Also most computers running my software are low end ATOM CPU. So I am thinking to return to GDI, EMF printing and have both Text-Only reports and EMF reports. Another reason i want EMF is because here receipts are signed by Electronic Fiscal Memory device.Most of these dont do good job extracting text from XPS as they dont follow the standard but how windows convert GDI to XPS.Even with text-only mode some of them dont support all character encodings and are impossible to send paper cut command after the sign. I know that using a reporting engine would solve rendering problem but I dont want to buy one. All I want is to be able to show tabular data and insert an image and replaced text.I know there is StringTemplate that could do the generation of template but the problem is i should parse somehow the template and render it using GDI commands. Is there any other solution/approach for this ? Or is there anything ready ?

• Do you believe it's a good idea for Software Engineers to have to work as Quality Assurance Engineers for some period of time?

  - by Macy Abbey

  I believe it is. Why? I've encountered many Software Engineers who believe they are somehow superior to QA engineers. I think it may help quench this belief if they do the job of a QA engineer for some time, and realize that it is a unique and valuable skill-set of its own. The better a Software Engineer is at testing their own programs, the less cost in time their code incurs when making its way through the rest of the software development life-cycle. The more time a Software Engineer spends thinking about how a program can break, the more often they are to consider these cases as they are developing them, thus reducing bugs in the end product. A Software Engineer's definition of "complete" is always interesting...if they have spent time as a QA engineer maybe this definition will more closely match the designer of the software's. What do you all think?

• How do you manage a complexity jump?

  - by glenatron

  It seems an infrequent but common experience that sometimes you're working on a project and suddenly something turns up unexpectedly, throws a massive spanner in the works and ramps up the complexity a whole lot. For example, I was working on an application that talked to SOAP services on various other machines. I whipped up a prototype that worked fine, then went on to develop a regular front end and generally get everything up and running in a nice, fairly simple and easy to follow fashion. It worked great until we started testing across a wider network and suddenly pages started timing out as the latency of the connections and the time required to perform calculations on remote machines resulted in timed out requests to the soap services. It turned out that we needed to change the architecture to spin requests out onto their own threads and cache the returned data so it could be updated progressively in the background rather than performing calculations on a request by request basis. The details of that scenario are not too important - indeed it's not a great example as it was quite forseeable and people who have written a lot of apps of this type for this type of environment might have anticipated it - except that it illustrates a way that one can start with a simple premise and model and suddenly have an escalation of complexity well into the development of the project. What strategies do you have for dealing with these types of functional changes whose need arises - often as a result of environmental factors rather than specification change - later on in the development process or as a result of testing? How do you balance between avoiding the premature optimisation/ YAGNI/ overengineering risks of designing a solution that mitigates against possible but not necessarily probable issues as opposed to developing a simpler and easier solution that is likely to be as effective but doesn't incorporate preparedness for every possible eventuality?

• How to get that first development job

  - by cju

  I have been in QA for 10 years, trying to get into developement for about 5 of them. I have taken classes in C++, Java and C#. I was able to write some tools and unit tests in C# at my current job and (by all accounts) did a good job of it. However, 8 months ago, my employer tasked me with the responsibility of establishing the new QA group. Now, I'm doing manual testing and deployment with no promise of returning to development. I have looked at the job boards and there are a lot of jobs for Web developers and wondered how I could break into that. I've picked up some books on Ruby on Rails that I plan to work through on the Mac at home, but I'm not sure employers would be interested in anything but commercial web development. Do you have any suggestions on how I can use my experience to get a job as a junior developer? And I mean one that entailes programming...the postings I've seen for junior developer amount to doing all the grunt work besides coding. They should just call them "Technical Secretaries".

• What are good reasons to use explicit interface implementation for the sole purpose of hiding members?

  - by Nathanus

  During one of my studies into the intricacies of C#, I came across an interesting passage concerning explicit interface implementation. While this syntax is quite helpful when you need to resolve name clashes, you can use explicit interface implementation simply to hide more "advanced" members from the object level. The difference between allowing the use of object.method() or requiring the casting of ((Interface)object).method() seems like mean-spirited obfuscation to my inexperienced eyes. The text noted that this will hide the method from Intellisense at the object level, but why would you want to do that if it was not necessary to avoid name conflicts?

• Actor library / framework for C++

  - by Giorgio

  In the C++ project I am working for we would like to use something like Scala actors and remote actors (see e.g. this tutorial). Being able to use remote actors (actors living in different processes, possibly on different machines and communicating via TCP/IP) has higher priority for us because we have an application consisting of several processes deployed on different machines. Being able to use several actors living in the same process (possibly different threads) is also interesting, but has lower priority for the moment. On wikipedia I have found some links to actor libraries for C++ and I have started to look at Theron. Before I dive too deep into the details and build an extended example with Theron, I wanted to ask if anybody has experience with any of these libraries and which one they would recommend.

• What is the use of Association, Aggregation and Composition (Encapsulation) in Classes

  - by SahilMahajanMj

  I have gone through lots of theories about what is encapsulation and the three techniques of implementing it, which are Association, Aggregation and Composition. What i found is, Encapsulation Encapsulation is the technique of making the fields in a class private and providing access to the fields via public methods. If a field is declared private, it cannot be accessed by anyone outside the class, thereby hiding the fields within the class. For this reason, encapsulation is also referred to as data hiding. Encapsulation can be described as a protective barrier that prevents the code and data being randomly accessed by other code defined outside the class. Access to the data and code is tightly controlled by an interface. The main benefit of encapsulation is the ability to modify our implemented code without breaking the code of others who use our code. With this feature Encapsulation gives maintainability, flexibility and extensibility to our code. Association Association is a relationship where all object have their own lifecycle and there is no owner. Let’s take an example of Teacher and Student. Multiple students can associate with single teacher and single student can associate with multiple teachers but there is no ownership between the objects and both have their own lifecycle. Both can create and delete independently. Aggregation Aggregation is a specialize form of Association where all object have their own lifecycle but there is ownership and child object can not belongs to another parent object. Let’s take an example of Department and teacher. A single teacher can not belongs to multiple departments, but if we delete the department teacher object will not destroy. We can think about “has-a” relationship. Composition Composition is again specialize form of Aggregation and we can call this as a “death” relationship. It is a strong type of Aggregation. Child object dose not have their lifecycle and if parent object deletes all child object will also be deleted. Let’s take again an example of relationship between House and rooms. House can contain multiple rooms there is no independent life of room and any room can not belongs to two different house if we delete the house room will automatically delete. The question is: Now these all are real world examples. I am looking for some description about how to use these techniques in actual class code. I mean what is the point for using three different techniques for encapsulation, How these techniques could be implemented and How to choose which technique is applicable at time.

• How can I keep directories in sync

  - by Guillaume Boudreau

  I have a directory, dirA, that users can work in: they can create, modify, rename and delete files & sub-directores in dirA. I want to keep another directory, dirB, in sync with dirA. What I'd like, is a discussion on finding a working algorithm that would achieve the above, with the limitations listed below. Requirements: 1. Something asynchronous - I don't want to stop file operations in dirA while I work in dirB. 2. I can't assume that I can just blindly rsync dirA to dirB on regular interval - dirA could contain millions of files & directories, and terrabytes of data. Completely walking the dirA tree could take hours. Those two requirements makes this really difficult. Having it asynchronous means that when I start working on a specific file from dirA, it might have moved a lot since it appeared. And the second limitation means that I really need to watch dirA, and work on atomic file operations that I notice. Current (broken) implementation: 1. Log all file & directory operations in dirA. 2. Using a separate process, read that log, and 'repeat' all the logged operations in dirB. Why is it broken: echo 1 > dirA/file1 # Allow the 'log reader' process to create dirB/file1: log = "write dirA/file1"; action = cp dirA/file1 dirB/file1; result = OK echo 1 > dirA/file2 mv dirA/file1 dirA/file3 mv dirA/file2 dirA/file1 rm dirA/file3 # End result: file1 contains '1' # 'log reader' process starts working on the 4 above file operations: log = "write file2"; action = cp dirA/file2 dirB/file2; result = failed: there is no dirA/file2 log = "rename file1 file3"; action = mv dirB/file1 dirB/file3; result = OK log = "rename file2 file1"; action = mv dirB/file2 dirB/file1; result = failed: there is no dirB/file2 log = "delete file3"; action = rm dirB/file3; result = OK # End result in dirB: no more files! Another broken example: echo 1 > dirA/dir1/file1 mv dirA/dir1 dirA/dir2 # 'log reader' process starts working on the 2 above file operations: log = "write file1"; action = cp dirA/dir1/file1 dirB/dir1/file1; result = failed: there is no dirA/dir1/file1 log = "rename dir1 dir2"; action = mv dirB/dir1 dirB/dir2; result = failed: there is no dirA/dir1 # End result if dirB: nothing!

• Is it common practice to hire third parties to do code reviews for contractors?

  - by blueberryfields

  I recently observed some contract offers which included a "code review by third party" clause - the contract would not pay out fully until the code review was completed and it received a pass. I was surprised, especially considering that these were fairly simple, and small-scale contracts (churning out vanity apps for the iPhone). Is this kind of third-party code review a common thing to run into when contracting out as a programmer?
