18:00 - 18:45
Processing 600M requests per day with a bit of PHP, JS & USD
(Michal Špaček, Web developer, security engineer, hax0r, @Report URI)

We love JSON. We love it so much we get 500M+ requests on a good day,
15k/sec peak.

Report URI is a browser & email reporting aggregator. The reports tell site
owners things like "this JS shouldn't be here", "this browser feature will
be deprecated", "your cert has expired" etc.

We run PHP, JavaScript, Cloudflare and 25+ machines. This is a story about scaling the hell out of it, using clouds and oceans. Oh, and two developers.

Michal is a software developer and an application security engineer who's on a mission to show developers how & why to write secure code. He started building web sites and apps during the "First browser war" when "Best viewed in Netscape" logos were still a thing.

Michal has worked for Skype and others and is half freelancing, half working on a reporting aggregator

18:50 - 19:10
Lightning talk #1: Serverless Machine Learning at
(Michal Šimon, CEO at

Source code analysis is a difficult task in the world of more than 450 different programming languages.
We use machine learning for language recognition as well as finding specific patterns in our client's codebases to help them improve their code quality and fight the technical debt.
Serverless is an integral part of Codeac's infrastructure which enables us to make our product secure and scalable. Michal will go through the main parts of the architecture and talk about the challenges we faced.

19:15 - 19:35
Lightning talk #2: Using Prometheus for monitoring of network devices via SNMP
(Štefan Šafár, Senior CDN Engineer @Showmax)

We're moving our monitoring to prometheus. We needed to gather more SNMP metrics, store them on our German servers, but gather data from South Africa. I'll tell you some war stories about this process and show you some awesome dashboards that we created.
