This is a guide on how to email securely.
There are many guides on how to install and use PGP to encrypt email. This is not one of them. This is a guide on secure communication using email with PGP encryption. If you are not familiar with PGP, please read another guide first. If you are comfortable using PGP to encrypt and decrypt emails, this guide will raise your security to the next level.
The easiest way to load the Mysql Time Zone tables from your Mac OS time zone fields is via this command:
mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql
However, on many systems like mine that will fail because some of the time zone information is incompatible with the database schema for the time zone tables.
Therefore, you'll want to load the time zone information into a text file and edit it to only include the time zones you need. (Or, attempt to find the data breaking the import.)
mysql_tzinfo_to_sql /usr/share/zoneinfo > zone_import.sql
A quick overview of the node.js streams interface with basic examples.
This is based on @brycebaril's presentation, Node.js Streams2 Demystified
Streams are a first-class construct in Node.js for handling data.
Think of them as as lazy evaluation applied to data.
This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.
The script is here:
#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"
When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:
const Article = require('../../../../app/models/article');Those suck for maintenance and they're ugly.
