  • How to make OSX application that just runs opens some file type and runs arbitrary Ruby code?

    - by taw
    It's trivial to make a program executable from shell - just put #!/usr/bin/ruby on top, chmod +x it and done. Unfortunately OSX won't let me associate file type with such scripts - it requires its .apps instead. This sort of distinction doesn't seem to exist on other operating systems. What's the simplest way of making such .app, which would merely execute some arbitrary Ruby code?

  • PHP Changing Class Variables Outside of Class

    - by Jamie Bicknell
    Apologies for the wording on this question, I'm having difficulties explaining what I'm after, but hopefully it makes sense. Let's say I have a class, and I wish to pass a variable through one of it's methods, then I have another method which outputs this variable. That's all fine, but what I'm after is that if I update the variable which was originally passed, and do this outside the class methods, it should be reflected in the class. I've created a very basic example: class Test { private $var = ''; function setVar($input) { $this->var = $input; } function getVar() { echo 'Var = ' . $this->var . '<br />'; } } If I run $test = new Test(); $string = 'Howdy'; $test->setVar($string); $test->getVar(); I get Var = Howdy However, this is the flow I would like: $test = new Test(); $test->setVar($string); $string = 'Hello'; $test->getVar(); $string = 'Goodbye'; $test->getVar(); Expected output to be Var = Hello Var = Goodbye I don't know what the correct naming of this would be, and I've tried using references to the original variable but no luck. I've come across this in the past, with the PDO prepared statements, see Example #2 $stmt = $dbh->prepare("INSERT INTO REGISTRY (name, value) VALUES (?, ?)"); $stmt->bindParam(1, $name); $stmt->bindParam(2, $value); // insert one row $name = 'one'; $value = 1; $stmt->execute(); // insert another row with different values $name = 'two'; $value = 2; $stmt->execute(); I know I can change the variable to public and do the following, but it isn't quite the same as how the PDO class handles it, and I'm really looking to mimic that behaviour. $test = new Test(); $test->setVar($string); $test->var = 'Hello'; $test->getVar(); $test->var = 'Goodbye'; $test->getVar(); Any help, ideas, pointers, or advice would be greatly appreciated, thanks.

  • NHibernate and MySql Keywords

    - by jalchr
    Why Nibernate HQL can not handle the following query: from Deal D where (D.ApprovalDate + INTERVAL 1 Year) < current_timestamp() < (D.RenewalDate + INTERVAL -1 Year) knowing that INTERVAL and YEAR are keywords in MySQL, so this is kind of mixing Sql within Hql (unless Hql can handle date functions like so and I don't know) . The dialect is MySQLDialect Its perfectly valid to execute this query SELECT '2005-01-01' + INTERVAL 1 Year;

  • Load Balancer Timeout

    - by Anilkumar
    "This website is temporarily unavailable. Please check back later. Unfortunately there were no suitable nodes available to serve this request." When I request a stored procedure from my program (SP is taking 2 minutes to execute) the above error is getting. I believe this is because of Load balancer Time out. How we can increment the load balancer time out.

    I have a site that I'm optimizing using Google Website Optimizer where the goal is to have someone click on a link to download some software. But the google optimizer code that's provided will get triggered on any page where the link is on. Is there any way to have it execute only when someone actually clicks the download button? Thanks so much!

  • How secure is .htaccess protected pages

    - by Steven smethurst
    Are there any known flaws with htaccess protected pages? I know they are acceptable to brute force attacks as there is no limit to the amount of times someone can attempt to login. And a user can uploaded and execute a file on the server all bets are off... Anything other .htaccess flaws?

  • JQuery: How do I perform a callback on JQuery once it's loaded?

    - by Teddyk
    I'm downloading JQuery asynchronously: function addScript(url) { var script = document.createElement('script'); script.src = url; document.getElementsByTagName('head')[0].appendChild(script); } addScript('jquery.js'); // non-jquery code ... // jquery specific code like: $()... As such - how do I call my JQuery specific code once JQuery is loaded (because since I'm downloading my JavaScript asynch - it's not blocking, which is good, but is trying to execute my JQuery specific code before JQuery has been loaded).

  • Is a server an infinite loop running as a background process?

    - by Tony
    Is a server essentially a background process running an infinite loop listening on a port? For example: while(1){ command = read(127.0.0.1:xxxx); if(command){ execute(command); } } When I say server, I obviously am not referring to a physical server (computer). I am referring to a MySQL server, or Apache, etc. Full disclosure - I haven't had time to poke through any source code. Actual code examples would be great!

  • Let varnish send old data from cache while it's fetching a new one?

    - by mark
    I'm caching dynamically generated pages (PHP-FPM, NGINX) and have varnish in front of them, this works very well. However, once the cache timeout is reached, I see this: new client requests page varnish recognizes the cache timeout client waits varnish fetches new page from backend varnish delivers new page to the client (and has page cached, too, for the next request which gets it instantly) What I would like to do is: client requests page varnish recognizes the timeout varnish delivers old page to the client varnish fetches new page from backend and puts it into the cache In my case it's not site where outdated information is such a big problem, especially not when we're talking about cache timeout from a few minutes. However, I don't want punish user to wait in line and rather deliver something immediate. Is that possible in some way? To illustrate, here's a sample output of running siege 5 minutes against my server which was configured to cache for one minute: HTTP/1.1,200, 1.97, 12710,/,1,2013-06-24 00:21:06 ... HTTP/1.1,200, 1.88, 12710,/,1,2013-06-24 00:21:20 ... HTTP/1.1,200, 1.93, 12710,/,1,2013-06-24 00:22:08 ... HTTP/1.1,200, 1.89, 12710,/,1,2013-06-24 00:22:22 ... HTTP/1.1,200, 1.94, 12710,/,1,2013-06-24 00:23:10 ... HTTP/1.1,200, 1.91, 12709,/,1,2013-06-24 00:23:23 ... HTTP/1.1,200, 1.93, 12710,/,1,2013-06-24 00:24:12 ... I left out the hundreds of requests running in 0.02 or so. But it still concerns me that there are going to be users having to wait almost 2 seconds for their raw HTML. Can't we do any better here? (I came across Varnish send while cache , it sounded similar but not exactly what I'm trying to do.)
