Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).

PostgreSQL & PostGIS Cheatsheet

This is a collection of information on PostgreSQL and PostGIS for what I tend to use most often.

TOC

• Installing Postgres & PostGIS
• Using Postgres on the command line: PSQL
• Importing Data into Postgres
• Exporting Data from Postgres
• Joining Tables

Solidity lets you program on Ethereum, a blockchain-based virtual machine that allows the creation and execution of smart contracts, without needing centralized or trusted parties.
Solidity is a statically typed, contract programming language that has similarities to Javascript and C. Like objects in OOP, each contract contains state variables, functions, and common data types. Contract-specific features include modifier (guard) clauses, event notifiers for listeners, and custom global variables.
Some Ethereum contract examples include crowdfunding, voting, and blind auctions.
As Solidity and Ethereum are under active development, experimental or beta features are explicitly marked, and subject to change. Pull requests welcome.
