// Bundling the .app is the first thing it does, and creating the DMG is the
// second. Making the DMG is optional, and is only done if you provide
// the template DMG file, which you have to create beforehand.

// Example use:

Where you able to produce a binary directly from the Rust build tools that you could submit to the app/play store?

---

Not quite, but I tried to get as close to that as was reasonably possible. Alas, things ended up a little convoluted.

For iOS, I have a nearly empty Xcode project with a build script that copies my cargo produced executable into the .app that Xcode generates (before Xcode signs it). The build script also uses lipo to merge the executables for each architecture I’m targeting (e.g. armv7 and aarch64 for non-simulator devices) into a single, universal binary.

On top of that, there are various iOS-y things that need to happen before my application’s main method is called. SDL2 provides the Objective-C code that does all of that. In a C or C++ game, SDL2 renames main to SDL_main, and then [inserts its own mai

#1. Download and install latest .deb for Unity3d from:
http://forum.unity3d.com/threads/unity-on-linux-release-notes-and-known-issues.350256/

#2. Download and install the Project Rider EAP (not sure if publicly available but you 
can sign up for early access here: https://www.jetbrains.com/rider/

#3. Open the Unity3d (.deb installs the executable at /opt/Unity/Editor/Unity )

Convert MOV to GIF using FFmpeg and ImageMagick

I tried a few different techniques to make a GIF via command-line and the following gives me the best control of quality and size. Once you're all setup, you'll be pumping out GIFs in no time!

Preparation

Install FFmpeg

• $ brew install ffmpeg [all your options]
  • Example: $ brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-frei0r --with-libass --with-libvo-aacenc --with-libvorbis --with-libvpx --with-opencore-amr --with-openjpeg --with-opus --with-rtmpdump --with-schroedinger --with-speex --with-theora --with-tools

Install ImageMagick

Why I Like Go

I visited with PagerDuty yesterday for a little Friday beer and pizza. While there I got started talking about Go. I was asked by Alex, their CEO, why I liked it. Several other people have asked me the same question recently, so I figured it was worth posting.

Goroutines

The first 1/2 of Go's concurrency story. Lightweight, concurrent function execution. You can spawn tons of these if needed and the Go runtime multiplexes them onto the configured number of CPUs/Threads as needed. They start with a super small stack that can grow (and shrink) via dynamic allocation (and freeing). They are as simple as go f(x), where f() is a function.
