I was looking for a replacement for the syntax highlighter I was using on my blog, since SyntaxHighlighter Evolved never really gave me satisfaction (unwanted advertisements next to the code blocks, poor styling).

Migrate Routines to Laravel
I had to work on a project that made heavy use of MySQL routines: stored procedures, views, functions and triggers. In the process of adding Laravel to the application, I found good packages to seed the database from existing data, create models from the existing schema and create migrations from existing tables.
Recently, I was looking for a way to deploy a Laravel application with ease and no headache. After some time, I wrote a very basic Bash script to automate the common deployment tasks: pulling changes from Git, installing Composer dependencies, building NPM scripts, running migrations and so on. But it was still feeling primitive. There had to be a better way.
As part of my Software Verification and Testing class at Concordia University, my team and I chose to study empirically the performance of some popular Laravel applications. The goal was to replicate the paper “How not to structure your database-backed web applications: a study of performance bugs in the wild” by Junwen Yang et al.
Recently, I had to counter a layer 7 HTTP Flood DDoS attack on my server, that is using CloudFlare. I started by setting up Fail2Ban using the Nginx logs, and Fail2Ban would ban attackers but they would still be able to hit my server. I finally understood that since they were passing through CloudFlare, I had to block them at a higher level, CloudFlare itself. Fortunately, CloudFlare offers a firewall and an API to block offenders.
Thus, the solution I found is to analyze Nginx’s logs with Fail2Ban, and trigger a ban once a certain threshold is met. We will ban the user from the server but also from accessing CloudFlare using their REST API.
