What mechanisms do you know that prevent your site from being abused by anonymous spammers. For example, let's say that I have a site where people can vote something. But I don't want someone to spam something all the way to the top. So I found (a) creating an account and only allowed to vote once and (b) CAPTCHA to decrease spam. What ...
I'm posting this on behalf of a co-worker. He gets a "The request was aborted: Could not create SSL/TLS secure channel" error while using a WebRequest object to make an HTTPS request. Th funny thing is that this only happens after a while, and is temporarily fixed when the application is restarted, which suggests that something is being...
When loading a page for the first time (!IsPostback), I am creating a button in code and adding it to my page, then adding an event handler to the click event. However, when clicking the button, after the page reloads, my event handler does not fire. Can anyone explain why? ...
Is there any benefit in using a blockquote over a div? I was looking at a website's mark up to learn css and I couldn't figure out why the blockquote was being used. EDIT: Yeah sorry I didn't clarify, it was used to hold the div tag with username as text and an input tag. There was clearly no quote. ...

It needs to allow fast development and enforce good development practices. The final application should be easy to deploy and handle well database migrations. The application will handle most of the time simp...
I'd like to do some server-side scripting using Python. But I'm kind of lost with the number of ways to do that. It starts with the do-it-yourself CGI approach and it seems to end with some pretty robust frameworks that would basically do all the job themselves. And a huge lot of stuff in between, like web.py, Pyroxide and Django. Wha...

I was wondering where and how I should start learning how to build a webpage from scratch. Which tools/technologies should I use? Any books to read? Websites to learn from? *I am previously experienced in Java, wi...
I'd like to get back into some web development after primarily working on native applications, and I'm looking for advice on how to set up my web development "stack" on my local Mac. Ideally I'd like a setup that is easy to setup and maintain, but remains flexible and extensible. In particular, I plan to use Python, so mod_python is ...

In my last job we ended up rewriting the complete ASP.NET stack (forms, controls, validation, postback handling, ajax library etc...) - the reason I was given was that the ASP.NET controls were not accessible enough, not were any of the third party controls that were assessed for the project. Can anyone point me to good accessible ASP.N...
I notice that Stack Overflow has a views count for each question and that these view numbers are fairly low and accurate. I have a similar thing on one of my sites. It basically logs a "hit" whenever the page is loaded in the backend code. Unfortunately it also does this for search engine hits giving bloated and inaccurate numbers. I ...
I am a web-developer working in PHP. I have some limited experience with using Test Driven Development in C# desktop applications. In that case we used nUnit for the unit testing framework. I would like to start using TDD in new projects but I'm really not sure where to begin. What recommendations do you have for a PHP-based unit test...
One of the problems I have come accross having complext tasks on the browser is with automatic timeouts. Currently our site has a sliding expiration of 30 minutes. Normally this isn't a problem because we use asp.net and most of the time the users update one or two fields and then submit the form. This obviously keeps the session acti...

Many websites, including this one, add what are apparently called slugs - descriptive but as far as I can tell useless bits of text - to the end of URLs. For example, the URL the site gives for this question is: http://stackoverflow.com/questions/47427/why-do-some-websites-add-slugs-to-the-end-of-urls But the following URL works j...
I am trying to create a horizontal menu with the elements represented by <span>s. The menu itself (parent <div>) has a fixed width, but the elements number is always different. I would like to have child spans of the same width, independently of how many of them are there. What I've done so far: added a "float: left;" style for every s...
