Few words about pragmatic software development.

Well, here is an interesting poll. In my opinion, the userbase of HN tends to be more open and experimental than the average programmer crowd and that makes these results even more interesting to me:

ps. I used the following quick-and-dirty script to parse the results. You can get the current results by running this:

var scores = {}, name, sign;
[].slice.call($0.querySelectorAll("tr:not([style])"), 0)
    .forEach(function(row, i) {
        if(i%2 === 0) {
            var nameAndSign = row.innerText.trim().split(" - ");
            name = nameAndSign[0];
            sign = nameAndSign[1] === "Like" ? 1 : -1;
            return;
        }
        scores[name] = scores[name] || 0;
        scores[name] += sign * parseInt(row.innerText.trim().split(" ")[0]);
    });
var scoresArray = [];
Object.keys(scores).forEach(function(key) {
    var entry = {};
    entry[key] = scores[key];
    scoresArray.push(entry);
});
scoresArray.sort(function(b,a) {
    return a[Object.keys(a)[0]] - b[Object.keys(b)[0]];
});
scoresArray.forEach(function(a) {
    var name = Object.keys(a)[0];
    console.log(name, a[name])
});

How do you get the minute difference between two 12-hour dates encoded in a string like

"12:05am-02:55pm"

?

Short Answer

You shouldn’t. Get your data properly!

But Still…

I hate myself.

The Problem

I hate clichés but there we go:

What is the 10 001st prime number?

The Solution

Let’s try a one-liner this time:

var a=[],b;for(b=2;10001>a.length;b++)a.some(function(c){return 0==b%c})||a.push(b);console.log(a.pop());

yay.

The Problem

Find the difference between the sum of the squares of the first one hundred natural numbers and the square of the sum.

The Solution

Supposed to be harder, or?

The Problem

What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?

The Solution

I know this can be calculated very easily with pen and paper but overcomplicating stuff is just fun, I guess =)
