debug-me - secure remote debugging
Debugging a problem over email/irc/BTS is slow, tedious, and hard. The developer needs to see the your problem to understand it. Debug-me aims to make debugging fast, fun, and easy, by letting the developer access your computer remotely, so they can immediately see and interact with the problem. Making your problem their problem gets it fixed fast.

A debug-me session is logged and signed with the developer's GnuPG key, producing a chain of evidence of what they saw and what they did. So the developer's good reputation is leveraged to make debug-me secure.

Haskell Concepts in One Sentence
After years of dragging my feet I've been learning Haskell with the help of a few friends. Many Haskell concepts can be quite daunting so I decided to write one sentence summaries to simplify them for myself. These are not by any means complete but are useful as a jumping off point. This post draws inspiration from hemanth/functional-programming-jargon and the Standardized Ladder of Functional Programming.

JOSE (Javascript Object Signing and Encryption) is a Bad Standard That Everyone Should Avoid
A lot of developers try to use JWT to avoid server-side storage for sessions. This is almost always a terrible mistake and invites developers to come up with clever explanations and workarounds instead of careful engineering.

The standard itself is bad and leads to insecurity.

So I decided to go on a treasure hunt and write about my findings in this blog post.

The Internals of PostgreSQL
In this document, the internals of PostgreSQL for database administrators and system developers are described.

PostgreSQL is an open source multi-purpose relational database system which is widely used throughout the world. It is one huge system with the integrated subsystems, each of which has a particular complex feature and works with each other cooperatively. Although understanding of the internal mechanism is crucial for both administration and integration using PostgreSQL, its hugeness and complexity prevent it. The main purposes of this document are to explain how each subsystem works, and to provide the whole picture of PostgreSQL.
