Make Ubuntu packages 90% faster by rebuilding them

TL;DR

You can take the same source code package that Ubuntu uses to build jq, compile it again, and realize 90% better performance.

Setting

I use jq for processing GeoJSON files and other open data offered in JSON format. Today I am working with a 500MB GeoJSON file that contains the Alameda County Assessor's parcel map. I want to run a query that prints the city for every parcel worth more than a threshold amount. The program is

Why Multiple SSH keys?

There are numerous reasons you may need to use multiple SSH keys for accessing GitHub and BitBucket

You may use the same computer for work and personal development and need to separate your work.

When acting as a consultant, it is common to have multiple GitHub and/or BitBucket accounts depending on which client you may be working for.

You may have different projects you're working on where you would like to segregate your access.

Check out the xinput command. xinput list will give you a list of input devices; find the ID of the one which looks like a touchpad. Then do xinput list-props <device id>, which should tell you what properties you can change for the input device. You should find one called something like Tapping Enabled and a number in parens after it (in my case, it's libinput Tapping Enabled (276). Finally, run xinput set-prop <device id> <property id> 1, and tapping should work.

To make the change permanent, find a way to run that command on startup. One way would be to add exec xinput set-prop <device id> <property id> 1 to ~/.i3/config.
