Revert the full commit

Sometimes you may want to undo a whole commit with all changes. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it.

git revert {commit_id}

About History Rewriting

Delete the last commit

Deleting the last commit is the easiest case. Let's say we have a remote origin with branch master that currently points to commit dd61ab32. We want to remove the top commit. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:

Unit testing Angular.js app with node.js, mocha, angular-mocks and jsdom	unit-testing-angular-js-app-with-node	2015-07-05T18:04:33Z	en	Majority of search result about unit testing Angular.js apps is about how to do it by using test frameworks that run the tests in a real browser. Even though it's great to be able to test your code in multiple platforms, in my opinion it creates a lot of boilerplate code and makes it hard to run the tests in, for instance a CI-server.

Testing Angular.js app headlessly with node.js + mocha

Lean unit tests with minimal setup

Uses capped collection, tailable cursors and streams.

What's here?

init.js recreates collection capped collection 'queue' on mongodb.
writer.js spams queue with new messages
worker.js processes all messages saved to queue,
onceWorker.js processes only unprocessed messages, so you can spawn several of them and each of your messages will be processed by only one worker.

Steps

= Problem =

timeit.timeit() doesn't let you pass local vars to the code to be timed.

= Solution =

(pdb) !import sys, timeit
(Pdb) !dv = (lambda sys=sys: (lambda **kw: setattr(sys.modules['__main__'], 'VARS', kw)))()
(Pdb) !tt = lambda s, sys=sys: sys.stdout.write('%.3g ms\n' % timeit.timeit(s, 'import sys; self = sys.modules["__main__"].SELF', number=10)/10.*1000)
