In the last 2 parts I mostly talked about proper indexing. But indexing is not everything. Sure, it might be helpful in some situations, but today I’d like to show you a situation where a search can be improved without them. Disclaimer: I failed to write queries returning proper results. I have no idea why […]
Optimizing Django Database Queries – Part 2
In the previous post about optimizing Django database queries I showed how to detect and improper use of indexes and what Django creates by default. Today I’d like to show a better usage of indexing on a potentially expensive operation which is text searching. Task: Search an Author By Name As you might remember the […]
Optimizing Django Database Queries
Before we move on to the topic, I’d like to apologize for the irregular updates, but I’m going through a few courses that take a lot of time. On the other hand, from time to time they result in inspirations for new posts. One of such a case is a course focused on working with […]
How to Manage Project Dependencies with GitLab – Part 2.

What is Staging Area in Git?
If you’re a software developer, you’re likely using Git on everyday basis. It’s a very useful tool that hardly anyone learns to use properly. I’d say it’s a little bit like with driving cars: we learn for a moment, pass an exam, then we don’t do anything to boost our skills. Sure, with time we […]
Black Sheep Suspends
I hoped it wouldn’t happen, but looking back at last few months I must say I can’t meet the goals I’ve set for myself.

Metasploitable Walk-through 1 – Reconnaissance
Welcome to the new series, which is going to be a tutorial-like walk-through of a popular metasploitable project.

HackPy Part 4 – pcap files analysis with scapy
