kkew3 / pickle_cached.py

Last active June 22, 2018 20:11

Cache function call (function name, positional arguments, keyword arguments) using pickle. The overhead could be huge, so don't try to use this decorator unless the decorated function call takes at least ten minutes to return.

Last active July 27, 2018 17:57

AutoHotKey script that toggles between arXiv abstract page and PDF. This script only supports Chrome for security (you won't want it to ruin other applications with possibly conflicting key bindings), but it's trivial to change.

	/*
	Under context of Chrome browser, and if the URL starts with "https://arxiv.org/":
	"Windows + Alt + P" - Go to PDF is in abstract page, and go to abstract page if in PDF

kkew3 / node-and-npm-in-30-seconds.sh

Last active September 21, 2018 22:07 — forked from isaacs/node-and-npm-in-30-seconds.sh

Use one of these techniques to install node and npm without having to sudo. Discussed in more detail at http://joyeur.com/2010/12/10/installing-node-and-npm/ Note: npm >=0.3 is *safer* when using sudo. The first two scripts work for me.

	echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
	. ~/.bashrc
	mkdir ~/local
	mkdir ~/node-latest-install
	cd ~/node-latest-install
	curl http://nodejs.org/dist/node-latest.tar.gz \| tar xz --strip-components=1
	./configure --prefix=~/local
	make install # ok, fine, this step probably takes more than 30 seconds...
	curl https://www.npmjs.org/install.sh \| sh
