Ubuntu tips

Ubuntu is great, but here are some tips to fix some issues that I regularly encounter.

Mouse doesn't seem quite right

If its a logitech mouse, install solaar with Unity/gnome extensions, sudo apt-get install solaar-gnome3. Then unplug the mouse and restart the system. Or try lomoco to manually configure.

wget

Wget is a handy commandline utility for grabbing stuff off the web. It is built into most UNIX systems. If you are on windows, install Git for Windows which comes packaged with Git Bash, a very handy UNIX terminal emulator (note: check if Git Bash has wget installed by typing wget --version. If it is not installed, check this Gist). Another handy windows option is MobaXterm.

Check all the commands by typing wget --help in your terminal.

How to update Grub boot order on multi boot system

When logged into Ubuntu, open terminal:

sudo nano /etc/default/grub

Change GRUB_DEFAULT= to the value you want, based on its position on the GRUB menu when your computer starts up (the top OS is 0). You can use the number or use the exact label like GRUB_DEFAULT="Ubuntu 15"

Install OpenRefine on Mac

Mac seems to have a few issues when trying to install OpenRefine. The official instructions are on the OpenRefine wiki, but this list brings together resources to trouble shoot some common issues.

  1. Open Refine needs Java JRE. OS X has a few issues with Java, many are documented at Oracle Java on Mac OS X. Older versions of Java are automatically disabled by OS X. Its best to go to the Java page and just download and install the most up-to-date version for Mac.

How to add more to Git Bash on Windows

Git for Windows comes bundled with the "Git Bash" terminal which is incredibly handy for unix-like commands on a windows machine. It is missing a few standard linux utilities, but it is easy to add ones that have a windows binary available.

The basic idea is that C:\Program Files\Git\mingw64\ is your / directory according to Git Bash (note: depending on how you installed it, the directory might be different. from the start menu, right click on the Git Bash icon and open file location. It might be something like C:\Users\name\AppData\Local\Programs\Git, the mingw64 in this directory is your root. Find it by using pwd -W). If you go to that directory, you will find the typical linux root folder structure (bin, etc, lib and so on).

If you are missing a utility, such as wget, track down a binary for windows and copy the files to the corresponding directories. Sometimes the windows binary have funny prefixes, so

You can’t perform that action at this time.
