Upgrading PostgreSQL from 9.4 to 9.6 on Debian Jessie

To use the most modern version of Postgres software we need to add postgresql repository. Edit /etc/apt/sources.list or create /etc/apt/sources.list.d/pgdg.list and add there a line: deb http://apt.postgresql.org/pub/repos/apt/ jessie-pgdg main Then import the repository signing key, and update the package lists:

wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update

Install a new version of PostgreSQL server.

Once the Debian upgrade finished, I used dpkg-query -l postgresql* to check which versions of postgres I have installed.

Git HowTo: revert a commit already pushed to a remote repository

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:

How I set up my Chromebooks' dev environment

Chromebook Setup Options

Option 1: Stay in Chrome OS

If you're writing bare-bones javascript for the browser, creating Chrome Apps and Extensions, or using remote coding apps like cloud9, Koding, or Nitrous, you may not need to install Ubuntu. Some tutorials can be done entirely within the browser. The tradeoff is that you won't have a full-featured command line, and you may hit a point where you can't install something that you need.

To start coding within Chrome OS, install Text or Caret as a text editor. (Text stores files in Google Docs and Caret stores the files locally on your machine, which may help you choose.) After that, you're good to go, since Chromebooks come with a browser installed.
