• Erlang programming exercises

  - by valya

  I'm learning Erlang. I've moved from Haskell so I don't want to and have to learn functional programming. But Erlang is quite specific because of the microprocesses. So, can you give me some examples which will be simple to test and measure and use all the power of Erlang?

• Sqlite table constraint - unique on multiple columns

This is what I have that is causing a SQLiteException with the message "syntax error".

• Change "cancel" text on dijit.Dialog close box?

  - by zberger

  Is there any possible way to change the "cancel" tool tip that pops up over the X box on a dijit.dialog? I just want it to read "close". I'm somewhat new to dojo. I expect this might be just a dumb question that has a really easy answer, but I am finding no examples. Thanks in advance.

• New functional languages

  - by AnnaR

  Functional programming has been around since at least 1958 (creation of Lisp), but is experiencing a renaissance now with old functional languages being dusted off and new functional languages being created. Which functional languages are there that are newly developed or are in the making? I realize that you can write purely functional programs in most high level languages, so with functional languages I imply languages that are specifically designed for functional programming such as F#. If you have links to tutorials, wikis or code examples I encourage you to add them to your answer!

• Integrating Apache Shiro with ASP.NET MVC

  - by Garry Shutler

  I'm looking at using Apache Shiro as a central authentication service for all our applications over a variety of platforms.

Does anyone know where I can find an example of how to do this?

  I'm trying to define a step to test the value of alt text of an image using capybara and the css selectors. I wrote one for input values based on the readme examples: Then /^I should see a value of "([^\"])" within the "([^\"])" input$/ do |input_value, input_id| element_value = locate("input##{input_id}").value element_value.should == input_value end But I can't figure this one out...something like: Then /^I should see the alttext "([^\"]*)"$/ do | alt_text | element_value = locate("img[alt]").value Anyone know how I can locate the alt text value?

  - by Mech Software

  I need a regex expert to help out on this one. Examples I've found on here and the net I cant seem to get right. I'm using PHP and I have the following regex expression /([^a-zA-Z0-9])GC([A-Z0-9]+)/ This matches items like GCABCD GC123A, etc. What i need to do is EXCLUDE GCSTATS from this. So basically I want it to work just as it has, except, ignore GCSTATS in the regex.

  Probably everyone knows about Chrome Experiments: http://www.chromeexperiments.com/ that contain some stunning examples of what JS is capable of.

• Higher-order unification

  - by rwallace

  I'm working on a higher-order theorem prover, of which unification seems to be the most difficult subproblem. If Huet's algorithm is still considered state-of-the-art, does anyone have any links to explanations of it that are written to be understood by a programmer rather than a mathematician? Or even any examples of where it works and the usual first-order algorithm doesn't?

• Netlogo programming question - is it possible to put balanced chemical equations in a model?

  - by user286190

  hi I was wondering if it was possible to put balanced chemical equations, and if possible including state symbols, in the existing netlogo model that i am using, i havenot seen any examples in the models library so was not sure if it was possible. I wanted the model to be able to allow the user to input a balanced chemical equilibrium equation, or the model displays the the equation so then the user can select from them if they do not want to enter their own any help will be greatly appreciated thanks for example ethane + oxygen -- carbon dioxide + steam C2H6 + O2 -- CO2 + H2O

• How to secure an AJAX call from a facebook canvas application.

  - by user259349

  Reading this Ajax example, http://wiki.developers.facebook.com/index.php/FBJS/Examples/Ajax#Working_Example I found the following line. I'm not sure what to understand out of it, how do you "check the sig values per Platform spec"? "Note: For brevity's sake we are trusting $_POST['fb_sig_user'] without checking the full signature. This is unsafe as anyone could easily forge a user's action. Always be sure to either use the Facebook object which is supplied with the client libraries, or check the sig values per Platform spec"
