Unfortunately PHP by definition is blocking. While this holds true for the majority of functions and operations you will normally be handling, the current scenario is different. The process which I like to call HTTP-Ping, requires that you only touch a specific URI, forcing the specific server to boot-strap it’s internal logic. Some functions allow … Read more

Just wanted to make clear that only the latest_receipt_info field is returning the latest renewed receipt. This is based on what we’re actually getting back from Apple. The relevant documentation is here on page 21. Although it states that latest_receipt and latest_receipt_info fields are “Only returned for iOS 6 style transaction receipts for auto-renewable subscriptions”, … Read more
Not at all a weird question – I’ve been trying to sell Angular to a lot of java developers and they ask this. I asked it myself when I was learning (I’m still learning, btw) If you take a ‘conventional’ java webapp as you’ve described and Angular-ize it, you’ve got to first take your server … Read more

As HTML5 Rocks puts it “Server-Sent Events on the other hand, have been designed from the ground up to be efficient.” Server-sent events open a single long-lived HTTP connection. The server then unidirectionally sends data when it … Read more

Imagine the user clicking on a simple link: <a href=”https://stackoverflow.com/hello”>Hello!</a> On a webapp that uses server side routing: The browser detects that the user has clicked … Read more

Update Since Meteor 1.0 you can just type meteor debug which is essentially a shortcut for the … Read more
It’s not AJAX, unless people are using the term improperly. As its name suggests, SSJS is JavaScript that runs on the server, interpreted by a standalone (i.e., browser-independent) JavaScript engine, like SpiderMonkey. Why bother? Well, one area I currently see it underutilized in is in data validation. With SSJS you write one piece of code … Read more
Send a redirect response with the cookie set; when processing the (special) redirected URL test for the cookie – if it’s there redirect to normal processing, otherwise redirect to an error state. Note that this can only tell you the browser permitted the cookie to be set, but not for how long. My FF allows … Read more
Exit code 143 means that your process was terminated by a SIGTERM. This is generally sent when you do any commands that require your dynos to restart (config:set, restart, scale down…).
