How do I learn to program? - (37signals) →
It took me some twenty-plus years to really learn how to program. It wasn’t for a lack of trying either, it was just that I was trying the wrong way. I tried to learn to program by following tutorials that created programs I didn’t have the slightest interest in keeping. I was trying to learn for the sake of learning.
Now I’m sure that works for some people. Intellectually curious for the sake...

Most important vim hotkeys and commands
I can say that I speak fluently vim. And there are not much hokeys and commands I have to remember .. Because some peoples think vim is difficult, I want to share with you the most important of these ..
Hotkeys:
o insert new line after cursor and enter insert-mode (almost all of my vim-sessions start with this ;)
i enter insert-mode
ESC quit insert-mode, go back to cmd-mode

Re: The social utility of hacker humor
[..] The people who write and maintain these jokes are expressing and reifying hacker values. This is especially important for us, because our avenues of cultural transmission are in some ways quite restricted. We don’t have a material culture; we use and borrow the tangible artifacts of the culture(s) around us, but we don’t really have any of our own other than ephemera like T-shirts and mugs...

WatchThe last video embeded .. Again: You want to watch this :)
Software engineering as it’s taught in universities simply doesn’t work. It doesn’t produce software systems of high quality, and it doesn’t produce them for low cost. Sometimes, even when practiced rigorously, it doesn’t produce systems at all.
That’s odd, because in every other field, the term “engineering” is reserved for methods that...

Year 10,000 problem →
The Year 10,000 problem (also known as the Y10K problem or the deca-millennium bug) is the class of all potential software bugs that would emerge when the need to express years with five digits arises. The problem can have discernible effects today, but is also sometimes mentioned for humorous effect. (via Ian)
Perl Golf
From the Wikipedia:
Perl “golf” is the pastime of reducing the number of characters (key “strokes”) used in a Perl program to the bare minimum, much as how golf players seek to take as few shots as possible in a round.
Next is one example.
Problem:
Your program will receive one number on the standard input, written out, e.g. ‘one’, ‘two’ or...

Nati Shalom (Gigaspaces):
Today, with the availability of large multi-core and large memory systems, there are more cases where you might have a single machine that can cover your scalability and performance goals. And yet, there are several other factors to consider when choosing between the two options:
Continuous Availability/Redundancy
Cost/Performance Flexibility
