I use Google Fit to track my health data extensively since the end of 2023. In the meantime, Google released Health Connect, which is a platform to store health data from different providers instead of them using the Google Fit API. In 2024, I got a new Phone (P9P), but my historical Google Fit data is not showing up on my new phone's Google Fit app. Now I found a workaround.
Cro is a German rapper and producer. He is known for blending rap with pop and has paved the way for rap music in the mainstream. I think he has cool songs.
Rayhunter by EFF is an open-source tool to detect cellular spying, aka IMSI catchers, aka Stingrays. This tool monitors the cellular network and detects anomalies. Specifically, it looks for IMSI requests, 2G downgrade, SIB types 6 and 7, and null cipher. It is originally written for the Orbic RC400L, which is hard to purchase in Europe. GitHub user m0veax has created a fork and documentation to bring Rayhunter to the TP-Link M7350, which is available in Europe.
I noticed today that I have been attending the Gulaschprogrammiernacht (GPN) for 10 years now.

2025-03-30 -Analyzing FIDO MDS: The Good, The Bad and The Ugly or Which Passkey Vendor to Buy
Passkeys are a new authentication method that is gaining popularity. They are designed to be more secure and easier to use than traditional passwords. This scheme is developed by the FIDO Alliance, who also offer a database of certified passkey vendors. This database is called the FIDO Metadata Service (MDS).

In the next years, I want to achieve a few things. The general theme is doing more computer science and security. I think I can realistically achieve these things, if not I need to analyze it. Some of these things are more important than others and some are a byproduct of the general direction.
When you plan out something, a project, a process or something else, you can generally take more simple approaches or more complex approaches. There are plenty of examples where you need a complex approach, because there are very high requirements, I think of RF, semiconductor manufacturing, data intensive applications. But there are also plenty of examples where you can take a more simple approaches. Complexity or simplicity are unrelated to the quality of the result.
I am often critical of my work. I think of things I did in the past and I think it was bad. I could have done it better. There are always people who are better than me, people who studies faster than me, people who did two bachelor degrees, people who had better grades, who published more papers, who published at better venues, who won best paper awards at a* conference and so on.
