• Force download through markup or JS

  - by mschoening

  Lets assume I have a file on a CDN (Cloud Files from Rackspace) and a static html page with a link to that file. Is there any way I can force download this file (to prevent it from opening in the browser -- for mp3s for example)? We could make our server read the file and set the corresponding header to: header("Content-Type: application/force-download") but we have about 5 million downloads per month so we would rather let the CDN take care of that. Any ideas?

• Monad in plain English? (For the OOP programmer with no FP background)

  - by fig-gnuton

  In terms that an OOP programmer would understand (without any functional programming background), what is a monad? What problem does it solve and what are the most common places it's used? EDIT: To clarify the kind of understanding I was looking for, let's say you were converting an FP application that had monads into an OOP application. What would you do to port the responsibilities of the monads into the OOP app?

• Supporting twitter-like user page urls with apache/php?

  - by user246114

  Hi, I'm using php on apache with mysql. I want to let users enter a url into their browser to see a custom user page for themselves, just like twitter does. For example, they could enter urls like: www.mysite.com/johndoe www.mysite.com/janedoe and see that user's page. How could I do this with php and apache? I don't want to create a folder on disk for every user like above, I'd instead kind of like to catch the url and generate the page on the fly for them, Thanks

• Methods in Ruby: objects or not?

  - by Mladen Jablanovic

  Inspired by this discussion, after some googling I wasn't able to find an answer to a pretty simple question regarding methods in Ruby: are they objects or not? There are different opinions here and there, and I would really like to hear, let's say, an in-depth explanation. I'm aware of Object#method method, which takes a method name and returns a Method instance, but, on the other hand, there's a similar thing you can do with blocks to make them into Proc instances, and blocks aren't objects, so what makes methods any different?

• How can I show just the icon of the currently selected option?

  - by Paul Tomblin

  Is it possible to have a bunch of <select> dropdowns in html that only display a small (say 10 pixels wide) icon, but when you click it the drop down has a list with the icons beside a descriptive string. (Let's see if ASCII art works on SO): [X] | X - Disable | | v/ - Enable | | O - Ignore | +-------------+ [O] [v] [X] Can that be done in CSS? Or in jQuery?

• How to get number of entries in a Lua table?

  - by romkyns

  Sounds like a "let me google it for you" question, but somehow I can't find an answer. The Lua # operator only counts entries with integer keys, and so does table.getn: tbl = {} tbl["test"] = 47 tbl[1] = 48 print(#tbl, table.getn(tbl)) -- prints "1 1" count = 0 for _ in pairs(tbl) do count = count + 1 end print count -- prints "2" How do I get the number of all entries?

• Redirecting only if user asks for the root of the domain nad are froma particular country

  - by lphmedia

  Hi, I need a rule and condition to handle this scenario: User from US visits www.domain.com, domain.com, www.domain.com/ or domain.com/ this should be redirected to www.domain.com/usvisitor/ However, if a user from the US visits www.domain.com/anydirectory it will let them straight through without a redirection occurring. eg. RewriteEngine On RewriteBase / GeoIPEnable On GeoIPDBFile /var/share/GeoIP/GeoIP.dat RewriteEngine on RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^US$ RewriteCond %{HTTP_HOST} ^domain.com$ [L] RewriteRule ^/$ http://www.domain.com/usvisitor$1 [L] I know the RewriteConditons and rules are wrong - just can't get my head around it!

• When not to use a private field

  - by coffeeaddict

  When should it be considered dangerous to use a private field all over the place in the methods of your class? I mostly just create the variable and set it to a default value like null. Then in my methods reference it and set it to an instance of that object type from the methods. I don't know if my question makes sense but let me know if it doesn't and I'll clarify.

• Waiting for a subset of threads in a Java ThreadPool

  - by David Semeria

  Let's say I have a thread pool containing X items, and a given task employs Y of these items (where Y is much smaller than X). I want to wait for all of the threads of a given task (Y items) to finish, not the entire thread pool. If the thread pool's execute() method returned a reference to the employed thread I could simply join() to each of these Y threads, but it doesn't. Does anyone know of an elegant way to accomplish this? Thanks.
