So, I've got a mandate to make our aged trillion lined Delphi app web based and it needs to make heavy use of the <canvas> element (HTML5 compatibility doesn't seem to be a big issue since we can just make our clients use a compatible browser the way we'd make them use a compatible version of Windows in the win32 envir...
I've been reading up on Entity Framework, in particular, EF 4.1 and following this link ( http://weblogs.asp.net/scottgu/archive/2010/07/16/code-first-development-with-entity-framework-4.aspx) and it's guide on Code First. I find it neat but I was wondering, is Code First supposed to be just a solution for rapid develo...
I've been reading two books about web usability issues and tests (Rocket Surgery Made Easy¹ and Prioritizing Web Usability²) and they claim some strategies and typical problems about website usability and how to lead them.

Our team is distributed in space and time, so we have no ability to discuss the architecture of the code in real time. How can we discuss it via documentation: write code interfaces/ comment/ modify, track history of the code architecture? Are there some specific tools for this?

I have been designing and developing code with TDD style for a long time. What disturbs me about TDD is writing tests for code that does not contain any business logic or interesting behaviour. I know TDD is a design activity more than testing but sometimes I feel it's useless to write tests in these scenarios. For exa...

I have read this questions and answers, but I still don't understand what exactly do I need to do if I dynamically link with a library that uses a LGPL license (the SDL library in my case). If I understand LGPL text correctly, I need to somehow provide the source for the library. Is this enough? If not, what else needs...
I am not talking about stealing code, or reusing someone's for profit. But I am assuming that if a program or plugin is distributed in a format where I can't readily view the source, that is a deliberate action on the part of the programmer. Is it acceptable to look anyway, for the purpose of learning? And if so, are ...
I'm wondering if there are any less-biased resources that give good, specific overviews of programming languages and their intended goals.

In a shop that is intended to be tight-knit and supportive, should it be part of the culture that senior developers are paired with junior developers as mentors? Or should this mentoring be something that is more organic and spontaneous, i.e. not required, but allowed to develop without artificial encouragement?
Is it better to assemble permanent teams of developers within the company that always work together, from project to project, or is it better to have dynamic teams that assemble for a project, and then dissasemble afterwards?

I've always been curious, how libraries such as DirectX, OpenGL and OpenAL are implemented. Do they use some sort of unified API provided by OS? Talk directly to kernel?

Here's some interesting debate going on between me and my colleague when coming to handle SOA exceptions: On one side, I support what Juval Lowy said in Programming WCF Services 3rd Edition: As stated at the beginning of this chapter, it is a common illusion that clients care about errors or have anything meaningful...
I saw today that Firefox released a new version (5). I tried reading about what was added and ran into this link.

When I start a new project, I often times immediately start thinking about the details of implementation. "Where am I gonna put the DataBaseHandler? How should I use it?

Is PHP-GTK widely used for desktop application? Is it recommended to use? Is there a big company who uses PHP GTK?
I need to verify what data wasn't downloaded yet. For example, how does Twitter or Facebook verify if a specific client has already dowloaded a piece of information? When a mobile app like twitter make a request to twitter.com will receive only new data but not data that it has already downloaded in old requests.

How do I "convert" the newly added teams to this methodology and way of thinking ...
This is just a question to think about. When you write technical documentation and programming comments, do you ever find yourself writing run-on sentences in order to be more precise? Is packing more technical information into one sentence better than creating many little sentences each with a little bit of technical ...
TL;DR What are the prospects of writing applications which are completely based on a REST database server (CouchDB) and web applications which directly access the DB instead of having a web server in between? I recently started looking up some NoSQL databases. MongoDB seems to be a popular choices. I also liked the pr...
One of the driving points behind OOP is code reuse. I am curious about the actual logistics of this and how others both in team or solo handle it. For example lets say you have 5 projects you have worked on and between them you have a ton of classes that you think would be useful in other projects. How do you store the...
I work in an environment where we have several different web applications, where each of them have different features but still need to do similar things: authentication, read from common data sources, store common data, etc. Is it better to build the shared functionality into a set of services, to be called by the web...

So, HTML5 is the Big Step Forward, I'm told. The last step forward we took that I'm aware of was the introduction of XHTML. The advantages were obvious: simplicity, strictness, the ability to use standard XML parsers and generators to work with web pages, and so on. How strange and frustrating, then, that HTML5 rolls...
How does one get started with web development for mobile devices (including phones)? I know some old good HTML & JS, but I'm wondering what the modern way is. To make it concrete, I need to implement a client for an enterprise app. Think of a login-protected dashboard for managers. Given that I only have basic knowledg...
I typically run across gurus at SO and other places (instructors, book authors etc.) that would say something along the lines "This will cause alignment issues" or other low level tidbits. I want to learn about all these tidbits that are relevant to programming. Now usually when I see low level books (computer archite...
We are writing a program that does a standard "auto update software on startup". If the software finds an update ready, it will start the update process and then exit (and not run the program).

I used to work alone on small to medium sized programming projects before and have no experience working in a team environment. Currently, there will be 3 of us in an in-house software development team that is tasked to develop a number of software for an academic institution. We have decided to use the web for the maj...
How do you track licenses for third-party libraries that you use in your software? How did you vet the licenses? Sometimes licenses change or libraries switch licenses--how do you stay up to date?

I have to create a table where each row needs to store 50 number values. Each row will always need to store 50 number values. If this was a smaller number of values, I would just make fields for each of the values, but because there are 50, this approach seems a bit cumbersome (but since it will always be 50 values,...
A knowledgeable friend recently looked at a website I helped launch, and commented something like "very cool site, shame about the inline scripting in the source code". I'm definitely in a position to remove the inline scripting where it occurs; I'm vaguely aware that it's "a bad thing". My question is: what are the r...
I'm working on an ASP.NET MVC app, and I've been getting into the habit of putting what seem like helpful and convenient getters into my model/entity classes.

Right now we are having to upload 3 separate images that are sized exactly right, prov...
In my current project (a game, in C++), I decided that I would use Test Driven Development 100% during development. In terms of code quality, this has been great. My code has never been so well designed or so bug-free. I don't cringe when viewing code I wrote a year ago at the start of the project, and I have gained a ...
I read Stephen Walther's article about Test Driven Development (TDD) and unit testing. I think it was an excellent article. The author makes a distinction between what he calls "TDD Tests" and unit testing. They appear to be different tests to him. Previous to reading this article I thought unit tests were a by-product...
I'm learning Ruby on Rails for a new project of mine. I am referring the book 'Agile Web Development with Rails' which shows how to build a shopping cart and they use scaffolding.

I use regular expressions on a daily basis, as my daily work is 90% in Perl (legacy codebase, but that's a different issue). Despite this, I still find lookahead and lookbehind to be terribly confusing and often unreadable. Right now, if I were to get a code review with a lookahead or lookbehind, I would immediately se...
This answer and the comments added to it show a way to disable several compiler warnings using #pragma directives. Why would one want to do that? Usually the warnings are there for a reason, and I've always felt that they're good reasons. Is there any "valid case" where warnings should be disabled? Right now I can't th...

There is some code which is GPL or LGPL that I am considering using for an iPhone project.

The question Is it illegal to rewrite every line of an open source project in a slightly different way, and use it in a closed source project? makes me wonder what would be considered a clean-room implementation in the era of open source projects.
