I had a raspberry pi 3a+ and the old raspberry pi touchscreen laying around. So I'm writing a custom dashboard for it using Rust/Slint[1]. It directly uses opengl without any display manager/window system. It mostly talks to home assistant. Right now, when I start a 3d print, it automatically switches to a view with live camera of the printer and some stats. I can monitor the status of my washer/dryer so I know when they are done (using cheap TP-Link Tapo smart plugs[2]). My favorite thing it does, is if any motion is detected on my Ring cameras, it just automatically pulls up that live feed. Took a little work to get decent playback performance but the pi 3a+ has hardware h264 decoding.
Its nice, overall, to have a little dedicated touchscreen on my desk that I can easily tweak to display whatever I want. Its silent and low power.
They also did this for the original steam controller, which I used a lot. When the back panel broke (its a trigger and battery cover) I was able to 3d print a replacement that has held up great.
I really want to know how he solved this problem, which I also face:
>last year i bought a Rodecaster Duo to solve some audio woes to allow myself and my girlfriend to have microphones to our respective computers when gaming together and talking on discord in the same room without any echo
When I read this, I thought that the author would be calculating the derivative of the potential energy with respect to nuclear charge for some reason. Here, the derivative being evaluated appears to be the atomic forces, using jax magic, as opposed to the standard Hellmann-Feynman theorem approach.
Calculating the derivative of the energy with respect to nuclear charge would be fun, as it would let you perform some type of "alchemy" smoothly changing from one element to another. I'm not sure that has any practical use.
I think that the audio we are listening too is from some ground recording station that isn't necessarily near the airport. We aren't listening to a recording of what the pilots heard or what air traffic control hears.
I can't believe how affordable Hetzner is. I just rented a bare metal 48 core AMD EPYC 9454P with 256 GB of ram and two 2 TB NVME ssds for $200/month (or $0.37 per hour). Its hard to directly compare with AWS, but I think its about 10x cheaper.
I play fortnite and marvel rivals with my family. We have lots of fun. I think this genre of game is fantastic if you play with people you know on voice comms. "Solo queuing" in these types of games is not fun for me at all, so I get what you are saying, but they are popular for a reason!
Just currently exploring how custom AI workflows (e.g. text to sql, custom report generation using private data) can help given the current SOTA. Looking to develop tooling over the next 3-6 months. I'd like to see what we can come up with before dropping $50-100k on hardware.
Do you think that you can use those machines for confidential workflows for enterprise use? I'm currently struggling to balance running inference workloads on expensive AWS instances where I can trust that data remains private vs using more inexpensive platforms.
Just in case anyone else reads this and is confused. MRIs only use radio waves. No ionizing (or visible or even IR) radiation is used. The strong magnetic fields are a risk (due to interacting with metallic items embedded in the body). The contrast agents also can cause some undesirable side effects.
I agree that DFT is an approximate solution to the Schrodinger equation, but what would you like to see them do? Quantum monte carlo or configuration integration? These methods do not scale well especially when heavy elements are involved. DFT is the current sweet spot for accuracy vs computational complexity in this field. Making DFT better has been an on-going effort for the 30-40 years at least. It is not an easy task. For many real world materials, DFT is the best we can do.
I'm in a similar boat. A UK bank thinks I'm one of their customers (someone with a similar name). The reply address is no-reply@ and I'm not about to call a foreign bank.
I use fusion 360 several times a week, but I'm not quite able to follow what you said. Can you provide an example or a link to where they announced this feature?
I would love to know. I currently have an embedded product using buildroot and as it is not exposed to a network at all, I don't have any worries about security. However, I'd love to hear of a nice mechanism to basically upgrade the system image in place. I imagine you could use something like a pair of partitions and just change the kernel boot parameters to point at the most recent one, but I'm curious about what solutions people use.
It is even easier to just say, given a fixed area of paper, and a finite printing resolution, there is a finite number of symbols possible?
Say you have a 1 in by 1 in area of paper and a printing resolution of 300 DPI then there are 300*300 total dots. If the printer is monochrome and each dot is either black or white then there are 2^(300^2) possible symbols.
Thermostats ensure that the average _kinetic energy_ remains constant (on average or instantaneously depending on how they are implemented). Your parent post wants to enforce the constraint that the total energy remains constant. So its a bit different from a canonical ensemble (NVT) simulation. This is a microcanonical ensemble simulation (NVE). This means you don't know if you should correct the position (controlling the potential energy) or the velocities (controlling the kinetic energy).
Basically, there will be error in the positions and velocities due to the integrator used and you don't know how to patch it up. You have 1 constraint; the total energy should be constant. There are 2(3N-6) degrees of freedom for the positions and velocities (if more than 2 bodies). The extra constraint doesn't help much!
Edit: Also, the only reason thermostats work is because the assumption is that the system is in equilibrium with a heat bath (i.e. bunch of atoms at constant temperature). So there is an entire distribution of velocities that is statistically valid and as long as the velocities of the atoms in the system reflect that, you will on average model the kinetics of the system properly (e.g. things like reaction rates will be right). In gravitational problems there is no heat bath.
I used to work at a company that wrote an atomic scale simulation package. Every dev was a physics/chemistry PhD turned coder. We didn't quite hit one comment for _every_ line of code, but we were close! At first I really hated this style; one comment every few lines. However, I eventually learned to kind of like it, even though it was a bit redundant.
I don't really have a point here, but I just wanted to echo your statement that the physicists-turned-coder style is real!
Its nice, overall, to have a little dedicated touchscreen on my desk that I can easily tweak to display whatever I want. Its silent and low power.
