Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real

My thoughts on MessagePack

Hi. My name is Sadayuki "Sada" Furuhashi. I am the author of the MessagePack serialization format as well as its implementation in C/C++/Ruby.

Recently, MessagePack made it to the front page of Hacker News with this blog entry by Olaf, the creator of the Facebook game ZeroPilot. In the comment thread, there were several criticisms for the blog post as well as MessagePack itself, and I thought this was a good opportunity for me to address the questions and share my thoughts.

My high-level response to the comments

To the best of my understanding, roughly speaking, the criticisms fell into the following two categories.

						// Encrypt where jo is input, and query is output and ENCRPYTION_KEy is key
						byte[] input = jo.toString().getBytes("utf-8");
						
						MessageDigest md = MessageDigest.getInstance("MD5");
						byte[] thedigest = md.digest(ENCRYPTION_KEY.getBytes("UTF-8"));
						SecretKeySpec skc = new SecretKeySpec(thedigest, "AES/ECB/PKCS5Padding");
						Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
						cipher.init(Cipher.ENCRYPT_MODE, skc);
						
						byte[] cipherText = new byte[cipher.getOutputSize(input.length)];

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style

MOC on OS X

I waited for years for a Homebrew formula for MOC. I finally found one today, but it didn't work for me. So I decided to try to compile it from source.

Requirements

Here is a list of requirements, taken directly from the MOC README:
