Installing Emacs 24.4 on Ubuntu 14.04 without sudo privilege

Just run:

sh ./ubuntu14.04-emacs-24.4-install.sh

This will install ncurses which is dependency of emacs24.4. It may requires another dependencies depending on your environment. Note that configure options in emacs installation are for disabling GUI features.

A script to interactively git-merge multiple future branches

This is usefull when you are working with open source codes and you have several future branches that you want to use and is still not merged to the main stream.

Workflow:

1. Edit variables BASE_BRANCH and BRANCHES
2. Run ./future.sh
3. If you see conflicts, fix them and commit, then run ./future.sh again.
4. Repeat 3, until you see the message Done. in the result of ./future.sh.

Behaviors of Python threading, multiprocessing and concurrent.futures

I saw the behaviors as follows:

1. threading.Thread and multiprocessing.Process do not raise to the main thread.
2. multiprocessing.Pool and multiprocessing.pool.ThreadPool (this is not documented at all) leave zombie threads.

The results show that concurrent.futures is the best choice for threading and multiprocessing in Python!

I did this experiment on Python 2.7.9, and Python 2.x does not have concurrent.futures, so I installed it by pip command pip install futures.
