• microformats, rdf or microdata

  - by Shlomi.A.

  Hi. is there any difference between using one of this technologies? I'm building now a site using HTML5, and I'm having hard time to decide which of them to use. I cannot see any difference between them, else the syntax size, which i'm not quiet sure is an advantage for the microformats side.

• PHP: Cookie only sent to http://www.xxx.com and NOT http://xxx.com

  - by Axel

  Hi, I have a php login which sets 2 cookies once some one login. the problem is that if you login from : http://www.mydomain.com and you go to http://mydomain.com you will find your self not logged in, I think that's because the browser only send the cookies to the first syntax. It's only one domain, the difference is the www. before the domain name, so how to set cookies to the whole domain whatever there is www. or not ? Thanks

• Do any JS implementations currently support (or have support on the roadmap for) fast, vectorized op

  - by agnoster

  I'd like to do a bit of matrix/vector arithmetic in JavaScript, and was wondering if any browsers or other JS implementations actually have support for vectorized operations, for instance for quickly summing the entries of two Arrays (or summing, or whatever). Even if that currently doesn't mean it compiles down to vectorized operations, at least some language support would be nice for when it does get implemented - I'd take the existence of functions or syntax to support it as a step in the right direction. (Understandably, "vectorization javascript" searches are pretty much all about graphics and SVG.)

• Ruby on Rails 2.3.5: update_all failing on ActiveRecord

  - by randombits

  I'm trying to update a collection of records in my database using ActiveRecord's update_all. Enter script/console. MyModel.update_all("reserved = 1", :limit => 1000) ActiveRecord thinks limit is a column, says it's unknown and throws an exception. According to the documentation though, my syntax looks sane. This is RoR 2.3.5. When doing MyModel.update_all("reserved = 1") alone, it works just fine.

• System.Timers.Timer/Threading.Timer vs Thread with WhileLoop + Thread.Sleep For Periodic Tasks

  - by Alan

  In my application I have to send periodic heartbeats to a "brother" application. Is this better accomplished with System.Timers.Timer/Threading.Timer or Using a Thread with a while loop and a Thread.Sleep? The heartbeat interval is 1 second. while(!exit) { //do work Thread.Sleep(1000); } or myTimer.Start( () => { //do work }, 1000); //pseudo code (not actual syntax)...

• Validating XML using XSD with regex pattern

  Hello, I am parsing a XML file against a XSD containing some regex patterns used for checking input data, but only this regex generates an error, even if it passes into the Eclipse XSD plugin: InvalidRegex: Pattern value '(((com|it|org)\.)+(\b[a-z]+[.]{1}\b)+)?[A-Z]{1}[A-Za-z]+' is not a valid regular expression.

• Nested Functions in C - Best Practices

  - by Justin Ethier

  I just realized a function may be defined inside another function in C: void main(){ int foo(){ return 2; }; printf("%d\n", foo()); } Besides being a neat trick, the useful thing about this is that the inner function is private to the outer function. But... is that a good enough reason to do this in a "real-world" application? What are the best practices for using this syntax?
