Discord Timestamps

Discord timestamps can be useful for specifying a date/time across multiple users time zones. They work with the Unix Timestamp format and can be posted by regular users as well as bots and applications.

The Epoch Unix Time Stamp Converter is a good way to quickly generate a timestamp. For the examples below I will be using the Time Stamp of 1543392060, which represents November 28th, 2018 at 09:01:00 hours for my local time zone (GMT+0100 Central European Standard Time).

Formatting

Style	Input	Output (12-hour clock)	Output (24-hour clock)
Default	<t:1543392060>	November 28, 2018 9:01 AM	28 November 2018 09:01

Memory Leak Testing in 2017

Hi, I am Andy, creator of leakage - the node-powered memory leak testing library.

Instead of manual debugging it provides a structured approach to fix or even prevent memory leaks.

How to set up stress-free SSL on an OS X development machine

One of the best ways to reduce complexity (read: stress) in web development is to minimize the differences between your development and production environments. After being frustrated by attempts to unify the approach to SSL on my local machine and in production, I searched for a workflow that would make the protocol invisible to me between all environments.

Most workflows make the following compromises:

• Use HTTPS in production but HTTP locally. This is annoying because it makes the environments inconsistent, and the protocol choices leak up into the stack. For example, your web application needs to understand the underlying protocol when using the secure flag for cookies. If you don't get this right, your HTTP development server won't be able to read the cookies it writes, or worse, your HTTPS production server could pass sensitive cookies over an insecure connection.

• Use production SSL certificates locally. This is annoying
