5 entertaining things you can find with the GitHub Search API

Let's have some command-line fun with curl, [jq][1], and the [new GitHub Search API][2].

Today we're looking for:

• The hottest repositories created in the last week.
• The oldest user accounts with zero followers. (So sad.)
• Issue trends by language.
• Clojure projects defying convention.

// Just before switching jobs:
// Add one of these.
// Preferably into the same commit where you do a large merge.
//
// This started as a tweet with a joke of "C++ pro-tip: #define private public",
// and then it quickly escalated into more and more evil suggestions.
// I've tried to capture interesting suggestions here.

How to set up user authentication for a Chrome Extension using the Chrome Identity API

1. Create a private key file, from which you can create the manifest key and Application ID, as detailed here: https://stackoverflow.com/questions/23873623/obtaining-chrome-extension-id-for-development
2. Add the manifest key to "key" in manifest.json
3. Create a new project in Google Developer Console https://console.developers.google.com/project
4. Go to "APIs & auth > Credentials" and create new client id for a Chrome Application using the Application ID generated in step 3.
5. Copy the Client ID to oauth2.client_id in the manifest.json

The Problem

Defining records in Haskell causes accessor functions for the record's fields to be defined. There is no seperate namespace for these accessor functions.

The Goal

Be able to

• use records in Haskell, which share field names.
• use lenses for accessing these fields
