tmux cheatsheet

As configured in my dotfiles.

start new:

tmux

start new with session name:

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
H: preserves hard-links
A: preserves ACLs

NetworkManager WiFi Power Saving

NetworkManager supports WiFi powersaving but the function is rather undocumented.

From the source code: wifi.powersave can have the following value:

NM_SETTING_WIRELESS_POWERSAVE_DEFAULT (0): use the default value
NM_SETTING_WIRELESS_POWERSAVE_IGNORE (1): don't touch existing setting
NM_SETTING_WIRELESS_POWERSAVE_DISABLE (2): disable powersave

I) Introduction

Taken from: [https://groups.google.com/forum/#!topic/devpi-dev/S-3ioWILTiY]).

We wanted to do some python developpement but we had a problem : our working network is completely isolated from any internet access, only having servers providing services like distribution packages repository mirror and web servers. The question then was how to make a full pypi mirror for usig pip install and pip search.

This is possible to be done using devpi, a web server, bandersnatch and an external hard drive. The idea is to dump all pypi packages with bandersnatch, transfer them to the server with the hard drive,

	"""Procrustes align two gensim word2vec models (to allow for comparison between same word across models).
	Code ported from HistWords <https://github.com/williamleif/histwords> by William Hamilton <[email protected]>.
	(With help from William. Thank you!)

	First, intersect the vocabularies (see `intersection_align_gensim` documentation).
	Then do the alignment on the other_embed model.
	Replace the other_embed model's syn0 and syn0norm numpy matrices with the aligned version.
	Return other_embed.

	"""
	Basic implementation of William Hamilton (@williamleif) et al's measure of semantic change
	proposed in their paper "Cultural Shift or Linguistic Drift?" (https://arxiv.org/abs/1606.02821),
	which they call the "local neighborhood measure." They find this measure better suited to understand
	the semantic change of nouns owing to "cultural shift," or changes in meaning "local" to that word,
	rather than global changes in language ("linguistic drift") use that are better suited to a
	Procrustes-alignment method (also described in the same paper.)
