I love the new shell but the one thing I missed from the old shell was the ability to use a pager like more or less to throttle the output of the screen.  Low and behold the engineers have added paging in MySQL Shell 8.0.13!!

Turn Paging On
Things can scroll off the screen quickly and pagination programs keep the output to small chunks.  To pick the more program as you pagination program, simply enter \pager more or for less enter \pager less

Yes, a to-do app, seems like something we’ve all done in the past. The great thing about a to-do app is that it covers all 4 aspects of CRUD; Create, Read, Update, Delete. As a developer, we need to know CRUD and a to-do app is the best way to start that learning or refresh some of the things we may be a little rusty on.

React is the frontend JavaScript library we are going to be using today. Whether you are new to React or are an avid React user, we can all agree on one thing: React is pretty great.

We've already done a React To-Do App here at Scotch, but that was with Class components. Today we will have no Class components by integrating React Hooks, React’s …

In the last few months, I had to install Percona Server 5.7 (PS5.7) on Debian a few times.  I was regularly annoyed by apt-get -y install percona-server-server-5.7 prompting me for a password.  But that annoyance did not push me to investigate the subject in detail: it was always a quick manual fix and Googling did not lead to a straightforward solution.  However in the last days, I had to

MySQL Shell makes it easy to develop tools you can use for example to generate reports. In a previous blog, I showed how to use external modules in MySQL Shell. In this blog, I will take it one step further and use the curses Python module to create auto-refreshing reports. The first example will be kept very simple to show the idea, then a more realistic example will be shown where the top N files sorted by I/O will be returned.

Note: Out of the box, this does not work on Windows as Python does not ship with the curses library. Basic Example

As a basic example, consider the query SELECT NOW(). This returns …

Recently, I did some maintenance on Innotop and I merged several pull requests including one to support MySQL 8.0 (thank you yoku0825 for the contribution).

As you know, Innotop is written in Perl and to be able to use it with MySQL 8.0, you need to have Perl DBD for MySQL compatible with MySQL 8.0 too (a driver that support the new default authentication plugin, caching_sha2_password).

If you are using Fedora 29, I created such package and you can download it here: …
