Python Particle Simulation

 I have started working on a particle simulator in python.  I have limited knowledge of Quantum Mechanics, but thinking about the weird way particles and entanglement work has lead me to some ideas that I want to try in a computer simulation of particles.  My idea is that certain properties not existing, or being described by probability functions will allow the simulation to run very fast with large numbers of particles.

I have been thinking about this for several years and made other attempts to get started. The current attempt is the furthest I have ever gotten. I have finally gotten it clear in my head what I want to do.

I am going to setup an array of particles.  Each particle will have a position and a direction.  When 2 particles interact I will optionally create more particles and select new directions for each particle.  At that point I will, using the direction of each particle, look for future interactions with other particles.  These interactions will go onto a queue that will be processed starting with the earliest event in time.

My thought is that doing this will mean that I only need to loop over the particles when an interaction happens, not for every frame like you would in a traditional animation type program.

I still haven't worked out all the details.  It is possible that it just doesn't work, or doesn't make sense in some way.

Canvas Paint

Here is another small JS project that I built quite a few years ago.  It was basically just an exploration of the canvas tag, which was somewhat new at the time.  I called it "Canvas Paint".  It allows you to draw on the canvas.  You can change the color and width of the brush by changing the numbers in the boxes and clicking either "Set Color" or "Set Width".

Life Game

Previously I posted about a game (really a simulation) that I made several years ago.  I called it the Fish Game.  A few years later I made another very similar simulation that I called "Life Game".

It is similar, but quite a bit more complex, and I think somewhat better written code.  In this version there are three life forms; fish, bugs, and plants.  The fish eat the bugs.  The bugs eat the plants.  The plants gain energy each frame as if they are getting energy from the sun.  Each life form has a fairly large set of properties.  These are copied to the individual life forms as they are created.

Custom Thumbnails for Magento 2 Products

I recently migrated a site from Magento 1 to Magento 2.  The product image thumbnails work differently in Magento 2.  In Magento 2 they use a JS library called Fotorama.  It has several options that can be modified in the view.xml if you have a custom theme setup.  However, none of the thumbnail options match the way that the thumbnails work in Magento 1, and my client wanted them to look more like the old version.

Fish Game

Many years ago, probably about twelve to fifteen, I was working on building a custom e-commerce system using Adobe Coldfusion.  I was a young developer and so were the rest of the developers I worked with.  Non of us were really qualified to build such a complex system, but we didn't know that, so we did it anyway.  It ended up working fine for the customers we had.  I'm sure I would not be happy with most of the code if I saw it today.

Playing Local Network Media on a Chromecast with Python

I have several Chromecast devices in my house.  Recently I was playing around with the Python module pychromecast.  It has given me a much better understanding of what the Chromecast does.  The module allows you to find devices on your network and play videos or other media on the device.

Using Brave

For a few weeks now I have been using the Brave browser.  It is based on Chromium, so switching from Chrome was a quick adjustment since I have been using Chrome for years.  Brave includes an ad blocking system that blocks what they call "very intrusive ads" and most attempts to track users across sites.  They have also setup a system using BAT currency that allows you to directly pay content providers that you visit.  I have also setup my site as a content provider so I can receive tokens.


Browser




The browser was created by Brendan Eich, the creator of Javascript.  The browser has worked well so far.  It updates automatically similarly to the way Chrome does.  They have a system for syncing bookmarks between your devices.  You also have a wallet built in for your BAT tokens.  I am using it on a Mac, and my Android phone.



AI and Aliens

 Maybe I'm just putting things together because they are both in the news recently, but I have come up with a theory about aliens. I thi...
