less than 1 minute read

Although Juno makes coding on iPad a breeze, there are still some tricks you need to know — one of them is working with the file system and handling paths. For example, when your code is supposed to read file’s contents or write data to a file, how do you specify file’s location in iOS?

Jupyter client for iPad

4 minute read

I have been a huge fan of Jupyter for a while now, and most importantly of the flexibility it is offering: I strongly believe that the fact that you only need a screen and network connection to get access to pretty much unlimited computational resources has enormous potential.

Self-signed SSL certificate in Jupyter Permalink

less than 1 minute read

In order to use Jupyter Notebook on iPad, one needs to correctly configure SSL certificates. Since issuing a proper certificate from a trusted authority could be challenging in some cases, a self-signed certificate should suffice, provided it was signed by a CA that is trusted by device. Follow these steps to get it working on your iPad!

Visualizing lidar data

4 minute read

Arguably the most essential piece of hardware for a self-driving car setup is a lidar. A lidar allows to collect precise distances to nearby objects by continuously scanning vehicle surroundings with a beam of laser light, and measuring how long it took the reflected pulses to travel back to sensor.

Detecting road features

16 minute read

The goal of this project was to try and detect a set of road features in a forward facing vehicle camera data. This is a somewhat naive way as it is mainly using computer vision techniques (no relation to naive Bayesian!). Features we are going to detect and track are lane boundaries and surrounding vehicles.
