Creating Timelapse Video From Photos With FFMPEG

Man, there are a lot of outdated and incomplete tutorials about creating timelapse videos from JPG images and photos. Here's a quick start guide to get going in late 2019.

Software

I'm using ffmpeg version 4.2.1 on MacOS. It is free, well supported, and scales up to practically any number of input images or output video length.

There are a dozen paid timelapse software offerings out there, but I suspect they are just polished front-ends to ffmpeg. Small timelapse videos are possible in iMovie 10.1, but adding even a modest number of images bogs it down badly. The easiest approach is to create a rough lightly compressed video with ffmpeg and then edit the result in iMovie.

A Simple Solution for Faked Tweets

Recently, a somewhat large selection of my timeline was shocked by the discovery that it's simple to make a fake-looking tweet on the web. Some feared it would be only a matter of time before some news organization is suckered by a fake tweet that seems to come from a real source.

Luckily, the solution already exists, and it's something you already use constantly: GNU PrivacyGuard signatures Here is an approach for verifying a tweet is authentic and hasn't been tampered with that is so simple even @KimKardashian could figure it out. To get started, we just need to do a little setup first:

1. Of course, you have already installed GnuPG for your own use, generated a keypair and uploaded it to a keyserver so that other people can look it up. Its email address must be publicly listed in your twitter profile.
2. Then, you must collect the public keys of the people you fo

Fibur

Fibur is a library that allows concurrency during Ruby I/O operations without needing to make use of callback systems. Traditionally in Ruby, to achieve concurrency during blocking I/O operations, programmers would make use of Fibers and callbacks. Fibur eliminates the need for wrapping your I/O calls with Fibers and a callback. It allows you to write your blocking I/O calls the way you normally would, and still have concurrent execution during those I/O calls.

Example

Say you have a method that fetches data from a network resource:

gavinheavyside

fizz    = [nil, nil, "Fizz"].cycle
buzz    = [nil, nil, nil, nil, "Buzz"].cycle

(1..100).zip(fizz, buzz) do |num, *fb|
  puts fb.compact.reduce(:+) || num
end

Open Conference Expectations

This document lays out some baseline expectations between conference speakers and conference presenters. The general goal is to maximize the value the conference provides to its attendees and community and to let speakers know what they might reasonably expect from a conference.

We believe that all speakers should reasonably expect these things, not just speakers who are known to draw large crowds, because no one is a rockstar but more people should have the chance to be one. We believe that conferences are better -- and, dare we say, more diverse -- when the people speaking are not just the people who can afford to get themselves there, either because their company paid or they foot the bill themselves. Basically, this isn't a rock show rider, it's some ideas that should help get the voices of lesser known folks heard.

These expectations should serve as a starting point for discussion between speaker and organizer. They are not a list of demands; they are a list of rea
