This launchd script will ensure that your Docker environment on your Mac will have 10.254.254.254 as an alias on your loopback device (127.0.0.1). The command being run is ifconfig lo0 alias 10.254.254.254.
Once your machine has a well known IP address, your PHP container will then be able to connect to it, specifically XDebug can connect to it at the configured xdebug.remote_host.
Copy/Paste the following in terminal with sudo (must be root as the target directory is owned by root)...

Install ImageMagick for image conversion:
brew install imagemagick
Install tesseract for OCR:
brew install tesseract --all-languages
Or install without --all-languages and install them manually as needed.
| literally always have to look up the meaning of :limit in migrations when it comes to integer values. Here's an overview. Now let's memorise it (oh, this works for MySQL, other databases may work differently): | |
| :limit Numeric Type Column Size Max value | |
| 1 tinyint 1 byte 127 | |
| 2 smallint 2 bytes 32767 | |
| 3 mediumint 3 byte 8388607 | |
| nil, 4, 11 int(11) 4 byte 2147483647 | |
| 5..8 bigint 8 byte 9223372036854775807 | |
| Note: by default MySQL uses signed integers and Rails has no way (that I know of) to change this behaviour. Subsequently, the max. values noted are for signed integers. |
One of the many things I do for my group at work is to take care of automating as many things as possible. It usually brings me a lot of satisfaction, mostly because I get a kick out of making people's lives easier.
But sometimes, maybe too often, I end up in drawn-out struggles with machines and programs. And sometimes, these struggles bring me to the edge of despair, so much so that I regularly consider living on a computer-less island growing vegetables for a living.
This is the story of how I had to install Pandoc in a CentOS 6 Docker container. But more generally, this is the story of how I think computing is inherently broken, how programmers (myself included) tend to think that their way is the way, how we're ultimately replicating what most of us think is wrong with society, building upon layers and layers of (best-case scenario) obscure and/or weak foundations.
*I would like to extend my gratitude to Google, StackOverflow, GitHub issues but mostly, the people who make the

docker-composebrewThis gist was originally created for Homebrew before the rise of Docker, yet it may be best to avoid installing mysql via brew any longer. Instead consider adding a barebones docker-compose.yml for each project and run docker-compose up to start each project's mysql service.

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.
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.
