Using Tiny (ID obfuscator) with Symfony2's ParamConverters

• Symfony's convenience methods for automatically fetching database entities from URL parameters are super-handy.
• Obfuscated/hash IDs are a great idea, especially in APIs (where you aren't concerned with SEO, but might be concerned about sequential numeric ids or exposing database information).
• Here's how to make them work together.

The stuff in this gist sets up a Twig filter (obfuscate) to create the obfuscated ids (for URLs), makes the obfuscator available as a service (id_obfuscator) so you can also generate obfuscated URLs in your controllers or whatever, and extends the DoctrineParamConverter to allow it to retrieve entities by their deobfuscated id.

Following Phil Sturgeon's excellent advice in Build APIs You Won't Hate, I've also added an option to allow multiple ids to be loaded at once, like /resources/id1,id2,id3,id4. It's really quite handy sometimes. Bewarned though; it won't

To terminate user sessions or queries on DB instances, Amazon RDS provides the following commands:

            PROMPT> CALL mysql.rds_kill(thread-ID)
            PROMPT> CALL mysql.rds_kill_query(thread-ID)
        
For example, to kill the session that is running on thread 99, you would type the following:

            PROMPT> CALL mysql.rds_kill(99);
        
To kill the query that is running on thread 99, you would type the following:

Easy pthreads Pools

The final solution !!

Since the first version of pthreads, PHP has had the ability to initialize Worker threads for users. Onto those Worker threads are stacked objects of class Stackable for execution concurrently.

The objects stacked onto workers do not have their reference counts changed, pthreads forces the user to maintain the reference counts in userland, for the extremely good reason that this enables the programmer to keep control of memory usage; and so, execute indefinitely.

This is the cause of much heartache for newcomers to pthreads; if you do not maintain references properly you will, definitely, experience segmentation faults.

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.
