A small fix can go a long way

Recently, I resumed using my MacBook Pro 2015 while my main Linux machine is down. However, when I started using it with my good old Logitech MX Master, the gestures were going crazy: thumb button acted as <Tab> and the backward button acted like a middle button.

The fix was surprisingly easy, however, I am not sure which step did the trick.

  1. Reinstall the latest Logitech Options

Beware! The default download link that appears in the search bar dropdown points to an ancient version!

Version 5.10.24 is super old…

You should go to the product’s page and download the latest one. (Mine was 7.12.82)

2. Reset the Options…

So today I went on with my Python Web Dev study with NoSQL. Evironment setup requires MongoDB and Redis so I just searched for the installation guide for these two packages. Sadly the official one for MongoDB does not work and Redis does not have such a thing (at least not as explicit as I would like). The guide from Digital Ocean was pretty detailed (and complicated) but I could not pass all the tests of make test. Luckily, there is a simpler way out.

Install MongoDB

sudo apt-get install mongodb

Installing the latest 3.6.x MongoDB is easier than I thought. A small trap here is that if you want to check the version, you should type mongod --version rather than mongodb --version. …
