Appreciate your help with my questions What are conceptual requirements? How do they compare with stakeholder, business and functional requirements? what CASE tools can be used to capture conceptual requirements and scope?
I am developing an iphone app and working through some sample code I saw, which uses libz.dylib. I did some research and found nothing enlightening, other than libz.dylib could be used for zip files, but other frameworks are prefered... I'm dealing with a pdf sample, so why use libz.dylib? In general, what are dylib? A...
In bidding a complex project for a client, I wanted a way to determine their reliance upon software. They have many people doing manual entry and Excel spreadsheets power many pieces as well as legacy code and some off the shlef solutions that do not interact in any way. Its one thing to say "You need software to run y...
I'm experimenting with a naming convention I've devised and am seeking opinion. It involves the use of an "As" infix, and at this point I am envisioning it in the context of JavaScript, C# and C++ coding to assist with clarity of data format/contract when dealing with conversions or multiple representations of the same...
I am looking for a good release notes template. Possibly in a plain text or HTML form. What do you guy use? EDIT: I forgot to mention that these notes will be used internally in our company for other developers using our libraries. I am interested in what you believe a release note should and should not contain. E.g. ...
I wasn't sure if this was more suited to here or StackOverflow. I've always resisted doing web development because the technology stack just seemed a mess. It seems the web has become quite popular so I'm actually going to embrace web development, at least for a little project I'm thinking about. I'm a Microsoft develo...
I am wondering what is the default graphics engine used in Photoshop? It's great tool. And I don't know how they make it? I mean, if I want to create a simple tool like it, I will use MFC/GDI+. So, what is core to make Photoshop being great tools?
I have an interview coming up for a company operating in the financial markets. Other than generic skills like OOD, refactoring, testing and so on, what are the core areas that a financial software developer specifically needs?

While it's almost impossible to apply for a freelance job without a sufficient portfolio/work experience, I see selling my scripts as a solution. Problem is, so far I've seen only one forum, where such trade is going on - DigitalPoint. Are there any more +/- trusted places to offer your scripts for sale?
I found a small bug in the microsoft mvc3 remote validation, concerning the clientside javascript implemented in jquerys unobtrusive javascript. The problem/bug can be fixed by adding a few lines to jquery.validate.unobtrusive.js which is bundled in the microsoft mvc3 installation. I can't seem to find a bug repository...

I've always found XML somewhat cumbersome to process. I'm not talking about implementing an XML parser: I'm talking about using an existing stream-based parser, like a SAX parser, which processes the XML node by node. Yes, it's really easy to learn the various APIs for these parsers, but whenever I look at code that p...

I'm considering a project to migrate part of our WCF-based SOA over to a service bus model (probably nServiceBus) and using some basic pub-sub to achieve Command-Query Separation. I'm not new to SOA, or even to service bus models, but I confess that until recently my concept of "separation" was limited to run-of-the-mi...
I work in a small company as a solo developer. I'm the only developer at the company in fact. I have several (relatively) large projects I've written and maintain regularly, and none of them have tests to support them. As I begin new projects I often wonder if I should try a TDD approach. It sounds like a good idea...
In a typical software development environment, project closures mark the end of a project. Project records are completed and archived, resources released, issues and lessons are documented, and a formal dinner/party held for celebration. Last step is optional, though is very motivating for participants. :-) Cont...

Notice how view counts of youtube videos are always laggy? For example, a video has like 1000 comments and still has 500 hits, and will have 10000 hits hours after. Youtube isn't alone in this. Most message boards are implemented that way and view counts are updated like every 10 minutes or so. Does anyone know the rea...
In your experience, what is a useful rule of thumb for how many lines of code are too many for one class in Java? To be clear, I know that number of lines is not even close to the real standard to use for what should be in a particular class and what shouldn't. Classes should be designed according to proper OOP philos...
I'm sure I am not alone in this issue so I wanted to see what others do to handle this problem. Whenever I have to reinstall my IDE, one of the first things I do is go out and look for addons. It starts out just grabbing whatever I plan on primarily doing but ends up with getting anything that looks interesting or may ...
I had a job interview today for a Job position as developer on an important site. They asked tonnes of programming language related questions, which I managed to answer without problems, but then they started asking question about how TCP/IP requests were made once I made a request on my PC to a web server. I did recei...
I've heard of TDD as an organizational development paradigm, where all developers are asked to let testing drive development, and I've also heard of organizations who don't embrace TDD so long as unit test coverage reaches close to 90 percent for the application. One thing I never hear is why an organization would set ...
Why has Python been backed by google and become so rapidly popular and Lua has not? Do you know why Lua has stayed in background?
I was recently thinking about the large variety of lisp languages, specifically the fact that while they all have similar syntax, and could all in theory be implemented from the same small set of primitive functions, the way in which one typically uses each lisp can vary widely compared to all the others. I realized th...
Programming isn't alien to me. I first starting doing markup (HTML, now please don't laugh at me) when I was 12 and a little bit of BASIC when I was 13 (I knew much about Flowcharts, Pseudocodes at this point), but then I was admonished into Biology in high school and hence missed out on "real" programming knowledge of...
I'm building a fairly complex interpreted program in Python. I've been working on most of this code for other purposes for a few months, and therefore don't want my client to be able to simply copy and try to sell it, as I think it's worth a fair amount. The problem is that I need the script to run on a server that my ...
I have created my own forum on ASP.NET MVC 3 and Razor. It's a decent forum with, say, version 1 functionality. I plan to work on other features as well after my release of this version. 1) What site apart from Codeplex can I post my application on as open source? 2) What are the guidelines I need to follow before pos...
I've always wondered how to apply agile methods really are in large complex embedded system software (100+ engineers). Firmware development has some unique characteristics that make it difficult to do agile (ie. Hardware is not available until late in the dev cycle; Once product is released, can't easily update firmwa...
I like languages that give me the ability to extend the syntax of the language. At the same time, all the languages that I know will let me extend the syntax have relatively heavy type systems. Are there lighter-weight languages that allow the same sort of syntax extensibility? Or does flexible syntax require that you ...
I need your opinions and suggestions about storing documents in a DMS system. I think the DMS should save its own copies of the documents, not their original path on the disk. So, the DMS should have its own space to write on. But what about the way they're stored? Do they have their own extension different from the or...

My current organization has stated clearly that I should not work on any freelancing projects in the fields where the company offers their service. I agreed to that and joined the organization.

There are still groups of programmers who support old microprocessors, e.g., Z80, 6510, 68000, etc. What can we learn from old assembly languages at a time when functional programming is becoming fashionable? EDIT I imagine that there would be more to learn for embedded systems. However, assembler styles apply to a mor...
As a rule of thumb, generalisation is used only in specific circumstances. For example, when we can say that X is literally a subclass of Y. So, we can happily say that a Horse is a subclass of Mammal. I have always been lead to believe that we should use generalisation and inheritence here. If we do not have this stri...
Imagine that an unfaithful (or maybe careless) employee at Microsoft managed to sneak in three lines of GPL code into a the core of a distribution of Windows. Wouldn't this mean that Microsoft would need to publish all their source code under GPL as well? Or could they just rewrite the three lines once they are notifie...
IMHO binding a variable to another variable or an expression is a very common scenario in mathematics. In fact, in the beginning, many students think the assignment operator(=) is some kind of binding. But in most of the languages, binding is not supported as a native feature. In some languages like C#, binding is sup...
Where I work we practice scrum-driven agile with 3-week iterations. Yes, it'd be nice if the iterations were shorter, but changing that isn't an option at the moment. At the end of the iteration, I usually find that the last day goes very slowly. The actual work has already been completed and accepted. There are a coup...
It looks like K&R "C Programming Language (2nd Edition)" covers ANSI C, but another book that I'm starting (Stephen G. Kochan "Programming in C") says that it uses C99. I'm coming from a C#/JavaScript/Python/PHP/Java background and looking to round out my skills. I'm currently using GCC, but I'm curious about Clang....
Does anyone know the testing activities carried out in an Object-Oriented development project that uses an incremental approach to development and delivery?
What is it about great APIs that makes them great? I think that adhering to the "do one thing and do it well" mantra is a good sign and being is a good mapping to the problem domain is important, but what do great APIs have in common?
What language should I seek to learn if I would like to develop for Windows? Not command-line stuff (obviously, I guess) but with Windows Forms and such? I've used C before (when working with Rockbox), but that's it. Up until now, I've used Autoit (for basic, simple stuff), but I'm looking for something that has more f...
Many programmers, upon first encountering Python, are immediately put off by the significance of whitespace. I've heard a variety of reasons that this is inconvenient, but I've never heard a complaint from a Python programmer. Of course, I haven't met a lot of Python programmers, as I have spent my career in the Java w...

I'm trying to work something out which isn't quite covered in any of the other "contractor vs employee" threads. In a nutshell: Is there a natural (possibly even hard-wired and inborn) tendency for people to be meant for one or the other? A bit of background: I suffered a serious burnout over the past couple of years ...
I wanted to get your thoughts. I see build systems like scons, make, jam, ants, autotools. Why do they exist? are they something like cross platform 'project files'?

One meme about Rails is that Rails can't Scale. Is it known how this meme started? Was there a particular blog post that argued this is the case?
I think most programmers prefer to work solo on projects, even when it's not feasible. I prefer to work alone, even outside of programming projects. When working with other developers, I typically find that I don't like their formatting or conventions (such as variable or method names) I don't have a good understandin...

I am considering open sourcing some software, but when I read the answers on this questions, it seems like the penalty of ignoring a GPL license is rather small, compared to the costs of the suing party to document that the other party has included GPL code in their proprietary code and the costs of suing.

If you were putting some work of yours online (say, a research project still in development or something alike) and it had to be made available to the public, but you wished that if someone uses it, he has to acknowledge the original author (i.e. you don't want anyone pushing your research as their own) what would be a...
I work in a company that runs on a model of using one developer as tech lead (me), with an onshore co-ordinator/developer who co-ordinates the offshore team, and on the offshore team there's an off-shore co-ordinator. It sounds bizarre but it basically works. The rest of the developers are offshore. I happen to be on...
Whether an object physically exists or not, we can choose to model it in different ways. We could arbitarily use generalisation or composition in many cases. However, the GoF principle of "favour composition over generalisation [sic]" guides us to use composition. So, when we model, for example, a line then we create a...
I find that when I am trying to learn something high level I end up worrying about problems that are out of scope like how is this thing implemented etc. For example, when I am learning Python's Twisted, I end up thinking how can Python define things in such a manner and stuff which leads me to worry mostly about inte...
I'd say that we're developing software in a world where the front-end of an application is probably the most important. The increasing ability for a user to access and interact with software almost instantly in the cloud is making the first few minutes of user interaction crucial in determining whether the application ...

Is there any data on which paradigms allow for code which is easier/cheaper to maintain?
