ESP32 Buyer’s Guide: Different Chips, Firmware, Sensors

Thu, Feb 02, 2023

The ESP 32 was the most fun side project for me in 2022. For those who don’t know: the ESP32 is a small, cheap and wifi-enabled microchip. Many smart devices that you buy on Amazon have an ESP32 inside. It’s really amazing what you can do with a board that costs less than a good sandwich.

You can build a small, low power WebCam for $7 (shipping from China included).
You can build a wireless temperature and humidity sensor, that sends you your current room temperature for $10 (again shipping included).
You can even run a small neural network on it to detect whether cat faces are running through your camera for $19.

Have I sparked your interest? Good. That’s why I’m excited about these chips.

Tips for beginners using Anki: the best software

Mon, Jan 16, 2023

Anki is my software of the year 2022. If you don’t know Anki, I highly recommend checking it out.

My Journey to Anki: Mind Palace

When I started my journey of using mnemonics to learn better, I first put everything into mind palaces. For a while this went great, but over time I found it very difficult to remember all the loci’s and as my palace grow, it would take me hours to go through the whole thing. it wasn’t practical. This is when I first found out about Anki and spaced repetition. It would help me tremendously remembering Loci’s. If you haven’t tried out Mind Palace, give it a try. It’s a perfect tool for remembering passwords and sequential data. It is not a great tool for random information Or remembering and learning something for a lifetime: that’s what Anki is for.

Swift and SwiftUI Learnings

Tips, Tricks and Stuff I want to remember

This is a living article. It’s not finished, and it’s written as I learn. It may be updated over time.

Don’t download Xcode from the App Store. Xcode is huge and takes a long time installing from the App Store. Instead, download it from Apple directly. This way you can see a progress bar and it’s way faster.
This is a struct (I would call it a dict in JS):

Build a Raspberry Pi NAS they said. It will be easy...

Build a Raspberry Pi NAS they said. It will be easy...

* Nobody said that, I had the idea myself.

First off, what were the goals? The NAS should be:

redundant and protect from a drive failure.
cheap.
an easy to use solution for my onsite backup.
powered by a single USB-C Cable.

Just connect two SSDs via USB to a Raspberry Pi 4 and run the NAS. What could go wrong?

Yeah, no:

Searching an E-Book for malicious code with VIM

Searching an E-Book for malicious code with VIM

Mon, Nov 30, 2020

I recently received a rather suspicious E-Book in epub format. Like PDFs, these can also contain malicious code. I wanted to open it, but I wasn’t sure if I could trust it.

In the past, I would have deleted it straight away. But this time I wanted to actually know if there is malicious code inside this file. So, how do I find that out?

You Are Planning Too Much

You are planning too much

Fri, Sep 11, 2020

Or at least this is one of the things I realized myself. Why do I say that?

I’ve built a project and I invested quite some time into it. I planned how to deploy it, how to market it, and how to launch it. But after some customer conversation, I realized: It will most likely fail.

So all these plans will not actually help me anything. It would have helped me a lot more if I have actually done these things: marketing & launching. If I had done that, I would have realized earlier that this project will fail.

Tipps to Code more secure Web-Apps

Mon, Aug 24, 2020

Disclaimer: I am not a security expert.

This post is a collection of quick tiny little things that could improve your security drastically. We would have a much safer web if more developers would know some of these resources and tips.

Use a checklist

This might sound a bit weird, but checklists are a great and powerful tool.

Ever heard of the Surgical Safety Checklist from the WHO? In their study, this checklist reduced the morbidity rate of patients by almost 50% ¹. This effectiveness will also apply to WebSecurity.
