To Repeat Yourself

by in CodeSOD on

Java’s history with web applications is, well, complicated. Java, heavily focused on being the True Object Oriented language, went the route of containers and service-providing classes and runtime bindings and dynamic hooks and lookups well before anyone else.

The core layer which underpins a lot of the web interactions is the Servlet specification. Servlets are just classes which are wired up to handle HTTP requests. Do whatever you want there. Slap a bunch of annotations for JAX-RS on there, and it’s a restful web service. Drop a JSP file in there, a it runs as a servlet with a template. Start playing with Java Server Faces? It’s servlets all the way down.


Now I Need an Injection

Frankie was handed a pile of PHP and told, "Move this to a new host." The process didn't go well- simply copying the code to the server chucked out a 500 error. So Frankie started digging into the code.

Like a lot of PHP code, this code wasn't written. It happened. A long chain of revisions, emergency fixes, quick and dirty hacks, and "I dunno what I did, but that fixes it," meant that it was a twisty pile of spaghetti that wasn't drained properly and now is all sort of sticking together into a starch blob that only vaguely resembles the pasta it once was.


Translatováno

Let’s say you’re a native English speaker. Let’s say you’re writing a library which is going to be used by Czech speakers, like our submitter Jan Krynický. You’ve been told to make sure the code is usuable by them, so you decided to use C#’s annotations to provide Czech documentation of various fields.

There’s just one problem: you don’t know Czech. You know enough to know that the Czech equivalent of “-ed”, as in “uploaded” is “-ováno”, so “uploadováno” seems perfectly reasonable to you. Czech documentation, done. It might not be the best choice, but they'll get the point.


Tern Java Into Python

Thomas K was browsing around, trying to give folks some technical help. While doing that, he found a poor, belaguered soul who had been given a task: convert some Java code to Python.

This was the code:
