Haskell: How is pronounced? [closed]
... .
Not quite as catchy as Monad, I think.
What all this basically boils down to is that Applicative doesn't correspond to any concept that's particularly interesting mathematically, so there's no ready-made terms lying around that capture the way it's used in Haskell. So, set the math aside for n...
Any idea why I need to cast an integer literal to (int) here?
...imes the synthetic sugar fails in subtle ways. I've had some hard to track down null pointer exceptions in large applications due to auto-boxing. We went as far as treating auto-boxing as errors in order to save headaches in the future. Magic is nice, but when it fails, heads hurt. I find it is bett...
How to disable XDebug
...xtension at all, and only load it, if needed. XDebug actually slows things down a lot, even if disabled. One might not feel performance has degraded that much, when debugging/profiling some scripts that create a web page, but with daemon scripts, it shows a lot. I just wrote a blog post on why not l...
git undo all uncommitted or unsaved changes
...lly equivalent to fresh git clone from original source (but it does not re-download anything, so is much faster):
git reset
git checkout .
git clean -fdx
Typical usage for this would be in build scripts, when you must make sure that your tree is absolutely clean - does not have any modifications ...
Serializing PHP object to JSON
...object type is custom, I would tend to agree with your solution - break it down into smaller segments using an encoding method (like JSON or serializing the content), and on the other end have corresponding code to re-construct the object.

Managing constructors with many parameters in Java
... projects, there's an class hierarchy that adds more parameters as it goes down the chain. At the bottom, some of the classes can have up to 30 parameters, 28 of which are just being passed into the super constructor.
