What this?

So one of the painful points of using docker on OS X is that you need to run a virtualbox VM, which often suffers from performance issues. With xhyve, a OS X virtualization system, and docker-machine-xhyve you can now have docker use the native OS X hypervisor to run containers.

No more dealing with virtualbox shenanigans!

In this script, I've also set up a way to autoconfigure terminal sessions to load docker's environment vars (dependent on docker-machine) so you do not have to run eval $(docker-machine env whatever) every time you open a new terminal window.

#        ./clone.sh TESTENV_TO_CLONE_DIR NEW_TEST_ENV_DIR
#        ./clone.sh TESTENV08-HOST TESTENV03-HOST
#	 The above will clone 08 to 03 and register the vm

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

• Close Android File Transfer
• Open Activity Monitor and kill “Android File Transfer Agent”
• Go to where you installed “Android File Transfer.app” (I have it under /Applications)
• Ctrl+click –> “Show package contents”
• Go to Contents/Resources
• Rename “Android File Transfer Agent” to e.g. “Android File Transfer Agent_DISABLED”
• Then go to “/Users/username/Library/Application Support/Google/Android File Transfer” and again rename the Agent app.

revolunet

General

• create a single page javascript application
• be as low-level as possible to be able to control performance (=minimize layers)
• masterize your dev/build environnement so you can work/play nicely

Debug apps

• Open safari console in development menu with simulator or attached devices (enable debug in ipad/safari dev options)
• debug your app from xcode to get native debugger and performance metrics

Combining two git repositories

Use case: You have repository A with remote location rA, and repository B (which may or may not have remote location rB). You want to do one of two things:

• preserve all commits of both repositories, but replace everything from A with the contents of B, and use rA as your remote location
• actually combine the two repositories, as if they are two branches that you want to merge, using rA as the remote location

NB: Check out git subtree/git submodule and this Stack Overflow question before going through the steps below. This gist is just a record of how I solved this problem on my own one day.

Before starting, make sure your local and remote repositories are up-to-date with all changes you need. The following steps use the general idea of changing the remote origin and renaming the local master branch of one of the repos in order to combine the two master branches.
