How to enter FEL mode on Lichee nano

If SPI flash isn't on the board, just remove the TF(microSD) card from the board and supply the power. It's the same if SPI flash is empty,

If your board have a SPI flash with preloaded image, pull D4(SPI CLK) down to GND. You can use the metal part of USB micro B or TF card slot as GND. Diagram is in the comment below. Thanks: @ernestp for the correction and providing a diagram.

Or you can use the special boot image [link]. Just write it to a TF card and boot.

Don't forget to remove the GND connection after entering FEL mode otherwise you will never be able to write the boot image to the SPI flash.

Creating a clean gh-pages branch

This is the sequence of steps to follow to create a root gh-pages branch. It is based on a question at [SO]

cd /path/to/repo-name
git symbolic-ref HEAD refs/heads/gh-pages
rm .git/index
git clean -fdx
echo "My GitHub Page" > index.html

libdispatch efficiency tips

The libdispatch is one of the most misused API due to the way it was presented to us when it was introduced and for many years after that, and due to the confusing documentation and API. This page is a compilation of important things to know if you're going to use this library. Many references are available at the end of this document pointing to comments from Apple's very own libdispatch maintainer (Pierre Habouzit).

My take-aways are:

• You should create very few, long-lived, well-defined queues. These queues should be seen as execution contexts in your program (gui, background work, ...) that benefit from executing in parallel. An important thing to note is that if these queues are all active at once, you will get as many threads running. In most apps, you probably do not need to create more than 3 or 4 queues.

• Go serial first, and as you find performance bottle necks, measure why, and if concurrency helps, apply with care, always validating under system pressure. Reuse
