I’ve always thought there were only two reasonable interpretations of quantum mechanics; Copenhagen (lots of dead cats, very unsatisfying) and many worlds (even more unsatisfying than dead cats) but today I learned about QBism and I was blown away. I seriously think this is (until now at least) the best interpretation; It is concerned with the interpretation of the  observer which is embedded in the system instead of seeing an observer as an outsider to the universe.

Schrödinger thought that the Greeks had a kind of hold over us — they saw that the only way to make progress in thinking about the world was to talk about it without the “knowing subject” in it. QBism goes against that strain by saying that quantum mechanics is not about how the world is without us; instead it’s precisely about us in the world. The subject matter of the theory is not the world or us but us-within-the-world, the interface between the two.

The publication we’ve written is now included in the IEEE Xplore library! I am super excited, you can access the paper by clicking the following link. Also the Git repository containing the algorithm and a short demo is still live and can be accessed through the following url: https://triangle1.net/repo/ReTS.git/. You can copy and paste this when creating a new project in RStudio or just use the Git command line to clone.

I actually made some additions to the algorithm such as variable cluster radii and tidied up the code a bit more in preparation for a new publication or conference, just didn’t have had the time yet to start writing and implement the new ideas. I am planning to update this site with some info and background on fuzzy self-learning algorithms, I’ll hope someone will find it useful and apply or modify the algorithm I have written.

If you are interested in machine learning, fuzzy systems and time series prediction you should definitely check this out though. I would like to thank Rui and Uzay from the Eindhoven Technical University for their great help and knowledge.

When I moved from sftp to ftps I experienced extremely slow directory listing (regardless of the client I used Cyberduck/Filezilla). I first suspected something was wrong with the passive mode (maybe it fell back to active mode or something) as I am behind a NAT router after all.

In the end it turned out to be the SPI firewall integrated in my Archer C8 router, so if you’re behind NAT and experience the same problems don’t forget to also check your integrated firewall.

PS This is why you never should use plain ol’ ftp in the first place.

So I’ve finally managed to get the TLS certificates working for all websites running on this server (note the green padlock on the left hand side next to the url, yay!). To get marked save by the major browsers I had to ditch all the embedded stuff (Soundcloud etc.)  so I converted everything to plain ol’ hyperlinks.

Certificates are provided for by Let’s Encrypt, an awesome initiative to distribute free certificates for regular server admins such as me! [link]. Set-up was fairly easy (I’m running Ubuntu server and Apache) too!
