I hate TDD, but I do it anyway.
I hate TDD.
TDD is slow. It takes longer time to ship features. This is obvious as you have to code for the features as well as the tests.
TDD is wasted effort. During the early turbulant stage of an application development when business requirements change like a 16 year old’s hairstyle, 90% of tests you write will become useless later. They are usually not salvageable either as features...

mysqldump is used to dump the data of one database to another database. Normally command for mysqldump to dump data from database1 to database2 goes something like the following.
mysqldump -h [host1] -P [port1] -u [user1] -p[password1] [database1] | mysql -h [host2] -P [port2] -u [user2] -p[password2] [database2]
But you might get this kind of error.

If you don’t, Passenger will spit out this error message.

Negate function in Eloquent Javascript's...
Just had a bit of wtf moment over this function from Eloquent Javascript.
function negate(func) {
return function(x) {
return !func(x);
};
}
Negate function takes another function as an argument. It returns another function that takes an argument. The other function that gets returned is a negation of the original function with the argument.
As an example,
var isNotNaN =...

Closure in Javascript
Sometimes javascript is really cool.
function makeAdder(amount) {
return function(number) {
return number + amount;
}
}
var addTwo = makeAdder(2);
addTwo(3);

edit: good catch, phortx. Thanks, it’s fixed now.

Nostalgia
We are a generation that wants to live in the past, not the future. Even when we dream about the future forward, we long it to belong in the past, the good old days. We live in a digital age that wants to emulate the lifestyles of analogue, slow but firm, a few in numbers but genuine, experience something rich and authentic. But we can never go back. There was a turn somewhere along the road,...

Editing hosts file for Android emulator on Mac OS...
Web developers who are using Android emulator to check the content on Android environment might have noticed that they can’t connect that localhost created by the local machine. This puzzled me as I thought the Android emulator running on local machine should have no problem accessing localhost created by the same local machine.

If your Cucumber test encounters a javascript alert in the browser, it will throw this sort of error.

Things I take when I move
I moved around so many times. Ever since I started going to university, frequency of moving around increased even more. I don’t think I’ve stayed in one place for more than a year since 2006. Because I moved so frequently, I had to really cut down on things I bring around.
Electronics
Macbook
Cell phone (not smartphone)

Currying in Scala
Coursera: Functional Programming Principles in Scala with Martin Odersky
Why Currying?
def sumInts(a: Int, b: Int) = sum(x => x, a, b)
def sumCubes(a: Int, b: Int) = sum(x => x * x * x, a, b)
def sumFactorials(a: Int, b: Int) = sum(fact, a, b)
The three functions above all have a, b as parameters. It gets passed unchanged from sumInts to sum. What if I told you Currying can get rid of...

Youtube Leanback gives a pretty awesome native app feel. I was wondering how their video is automatically resized to fit the browser. I tried to use Chrome inspector to checkout how Leanback video is resized, but the code is minified to obscurity that you can’t read it. I also checked out fitvidsjs and Chris Coyier’s solution to similar problem. But these two suggestions work only for...
