• In a pylons web app, should a cookie be set from a model class or a controller?

  - by ensnare

  Trying to figure out the best way to do this: Should I do something like: def index(self): if request.POST: u = User(id) u.setCookie() #All session logic in def setCookie() Or set the cookie in the controller like: def index(self): if request.POST: u = User(id) response.set_cookie('session_key', u.session_key, max_age=3600) Why do it one way or the other? Thank you.

• jQuery find text and replace (or BBcode hack)

  - by Harvengure

  Basically I am attempting to use jQuery so that it will search out text on the page and replace it with something else. For example [x]text[/x] will be converted to text which then gets converted from text to the actual html...a round about way of it I am sure but it seems to be the best way to do it given that the forum seems to understand html as plain texst anyway...but ultimately the goal is to use this jQuery to in a way create new bbcode on the forum.

• How to replicate PS multiply layer mode

  - by Andrew Philpott

  Does anybody know of a good way to replicate Photoshop's multiply layer mode using either an image or CSS? I'm working on a project that has thumbnails that get a color overlay when you hover over them, but the designer used a layer set to multiply and I can't figure out how to produce it on the web. The best thing I've come up with is either using rgba or a transparent png, but even then it doesn't look right.

• Letting users trial your web app before sign-up: sessions or temp db?

  - by Mat

  I've seen a few instances now where web applications are letting try them out without you having to sign-up (though to save you need to of course). example: trial at http://minutedock.com/ I'm wondering about doing this for my own web app and the fundamental question is whether to store their info into sessions or into a temp user table? The temp user table would allow logging and potentially be less of a hit on the server correct? Is there a best practice here?

  I have a situation where I have Model A that has a variety of properties. I have discovered that some of the properties are similar across other models.

• Looking for interesing formula

  - by Thinker

  I'm creating a game, where players can make an alloy. To make it less predictable, and more interesting, I thought that durability and hardness of an alloy can't be calculated by simple formula, because it will be extremely easy to find extrema, where alloy have best statistics. So the questions is, is there any formula for a function, where extrema can be found only by investigating all points? Input values will be in percents: 0.0%-100.0%. I think, it should look like this: half sound wave
