2021 Updated! Install WordPress on Ubuntu Server with add-on features as HTTPS support, SSL certificate and HTTP2 supports

If we carefully followed all my steps above , you should have a running wordpress page by now.
You might need to run as the wordpress uses php file extensions.
sudo rm -rf /var/www/html/index.html

Enable HTTPS supports:

Create a ssl-params.conf file and add the following definition below to it, then save it.

Next thing to do is create a backup of the original default-ssl.conf file.

Then modify it accordingly, we are deploying a wordpress site in this particular example we use the following adjustments.

Enable HTTP2 supports:

It is also recommended adding strong ciphers for Apache to increase SSL Security on the server.
Part of my Best Practices to deploy a secure webserver, virtual personal server or database serve is to add the recommended ciphers from SSL Server Test.

Valgrind 3.16.0 for MacOS Mojave 10.14.6

After many unstable versions and unsuccessful tries found a working but still experimental solution for MacOS Mojave 1.14.6 using homebrew. This solution also working with Qt5.14.1 using QtCreator 4.11.2 on Mojave 10.14.6.

My conclusion after carry out some analysis on some of my cross platform projects, simple and more complicated once. This solution works on simple projects, however as the complexity increases the results are totally unpredictable.

I’d like to emphasise that after comparing my results, I still NOT recommend to rely on results running Valgrind on MacOS, found fairly high number of critical errors and false positives. My results based on comparing the two following development environments:

– MacOS Mojave 10.14.6, Valgrind 3.16.0, Qt5, gcc, clang
– Ubuntu 18.04, Valgrind 3.16.0, Qt5, gcc, clang

Hardware Probe Tool for Linux

This project really deserves a post, just came across with it and will definitively use it. The HW PROBE project aim to collect hardware details of Linux-powered computers over the world and help Linux users and developers to collaboratively debug hardware related issues.

There are other very useful tools on their main git repository, if you need to collect more specific hardware details, these tools will come very useful.
