Hello software developers,

Please check your code to ensure you're not making one of the following mistakes related to cryptography.

I. General Mistakes

Writing your own home-grown cryptography primitives (For example: Mifare Classic)
- Exception: For the sake of learning, but don't deploy it in production.
Using a fast hash function (e.g. MD5, SHA256) for storing passwords. Use bcrypt instead.
Not using a cryptographically secure random number generator

rage-quit support for bash

HOW TO INSTALL

Put flip somewhere in your $PATH and chmod a+x it.

Copy fuck into ~/.bashrc.

Sabretooth

Anyway, we do use a custom service written in C++ that holds all of the tag data in-memory. Each tag holds ordered set of topic IDs. The order is by last post time and then by topic ID for tie breaking; this ordering is consistent between different tags, which gets important later. If you iterate through one of these sets you'll get all the topics tagged with that tag, most recently updated to least recently updated.

Tags also define and implement a very simple cursor interface. This interface is basically three functions; "advance the cursor by one topic", "advance the iterator until it's pointing to or past this topic (passing in a reference topic)", and "give me the currently pointed-to topic". When you are talking to the service, you can say "skip 50 topics and then give me 50 topics", and it will advance the cursor 50 times and throw away the result, and then advance the cursor 50 more times while returning each result. Pretty straightforward.

The cursor interface is also implemen

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	CREATE TABLE accounts(
	id serial PRIMARY KEY,
	name VARCHAR(256) NOT NULL
	);

	CREATE TABLE entries(
	id serial PRIMARY KEY,
	description VARCHAR(1024) NOT NULL,
	amount NUMERIC(20, 2) NOT NULL CHECK (amount > 0.0),
	-- Every entry is a credit to one account...
