DigitalOcean FTW

In the past, DigitalOcean had a big security issue, and I told people that I don’t recommend using them. They responded to the issue pretty well, but I felt that the issue they had should not have happened in the first place.

Some time has passed since then without any major issues, and they hired an all-star systems administrator. Recently I was working on a project using AWS, and in my search for information, I came across some useful tutorial pages on their site. Because of this, when the time came to switch hosts for my personal site, I started using DigitalOcean and have had a great experience. I can heartily recommend them now.

Of course, they may still have major security issues, but I expect that they’ll have better than average security going forward.

jschain: converting strings to and from binary (#14)

Encoding to binary:

'hello'.replace(/./g, function(c) {
function pad(n) { return (n > 0) ? ('0' + pad(n - 1)) : ''; }
var s = c.charCodeAt(0).toString(2);
return pad(8 - s.length) + s;
});

Decoding binary to a string:

'011101110110111101110111'.replace(/.{8}/g, function(s) {
return String.fromCharCode(parseInt(s, 2));
});

jschain: meanjs (#11)

I like building up a project from small parts but sometimes it’s good to try using a full framework to see what parts I’m missing. Today I tried starting a mean.js app with yeoman. It comes with a lot preconfigured, including five different authentication options, and since I chose it, an articles model. I removed four of the five authentication modules and changed the name of Article to Bin. In the process I found where things are stored in mean.js. It seems to do a good job of following the rails mantra of Convention Over Configuration.

  • The Code (unfinished, and most of it isn’t mine, the commits show what I did)

I want to return to this experiment and get it working the rest of the way and deployed on Heroku. The basic idea is a minimalistic jsfiddle.

jschain: map with d3 (#10)

I used d3 to make a map. It was good practice. I had forgotten how d3?s chaining API works. When a function mutates an element, it returns the same element back. When a function appends something to an element, it returns the new element back.

I also tried using patterns in svg. I still have to learn some more to understand them and to get the results I want, and I also need to brush up on biezer curves.

Update: I adjusted the vertical offset of the pattern to remove gaps between states.

jschain: grunt, unindented (#8)

A lot of node programmers like to code on the left margin. This is made possible by JavaScript’s dynamic nature. Prototypes can be built up and exports.

In Grunt the examples and virtually all code are wrapped up in one big function. Gulp doesn’t require this, and I’m under the impression many prefer this. However Grunt has a huge standard library.

I like code that doesn’t leave the left margin for long because it’s easier for me to see chunks of code. It also allows me to interleave code, which sometimes makes a lot of sense.

Using OOP, Grunt can be made to have this style. I took the Gruntfile for jquery and made it stay to the left margin while working the same way.

I won’t be sending a pull request, but I may do this on one of my own projects.
