rafinha··on Show HN: Think Turing Complete, but you write the circuits in TypeScript (WIP)
I think the "Turing Complete" part is about the "It has a campaign its not just a ts-to-circuit compiler"
rafinha··on Software engineers can no longer neglect their soft skills
The classic "technically strong but lacking soft skills" unheard story about you through the office after your results.
rafinha··on Show HN: Circuit Artist – Circuit simulator with propagation animation, rewind
Wow, thanks for the kind words!
rafinha··on Show HN: Circuit Artist – Circuit simulator with propagation animation, rewind
Hi thanks! Sure, certainly! I also want to eventually add some physics-based levels for fun, with like a box2D sim interacting with the circuits (with N circuit ticks = 1 box2D "tick"), or even little games on top of the circuit, but I need these tutorial campaigns first otherwise the step curve is way too high.
rafinha··on Show HN: Circuit Artist – Circuit simulator with propagation animation, rewind
Hi, thanks! Today the game is focused on digital logic, It would be fun to put resistors, capacitors or maybe transistors, maybe as a mod, but the algorithm would be a little different, would need analog simulation which I'm less familiar with.

Would probably be slower but doable, fun mod for the future!

Thanks!
rafinha··on Circuit Artist – Pixel art circuit design with NANDs, now with rewind and layers
Thanks! Yeah I got inspiration from Wireworld and Wired logic , just wanted to build a "paint" layer on top of it one day but i end up adding more and more :)
rafinha··on Circuit Artist – Pixel art circuit design with NANDs, now with rewind and layers
Hello, I've just added some new changes to my circuit simulation and game and wanted to share it here.

The game is open source and available in full in Github and on Steam:

https://github.com/lets-all-be-stupid-forever/circuit-artist

https://store.steampowered.com/app/3139580/Circuit_Artist/

More info on the github page, thanks.

rafinha··on Way past its prime: how did Amazon get so rubbish?
The genious leadership at prime video thought it would be a good idea to introduce adds not only on the beginning of movies but also in the middle of it, with an extra paid option (on top of prime) to remove it. When an add appeared I got so frustrated I cancelled my prime subscription at that very moment. I wonder if they even considered/cared about brand reputation impact.
rafinha··on Show HN: The current sky at your approximate location, as a CSS gradient
Same!
rafinha··on The Alexa feature "Do Not Send Voice Recordings" you enabled no longer available
It's handy for non-tech-savy people, namely the elderly. It can be used for playing music: "Alexa play X", "Alexa shutdown" is all the user needs to know.
rafinha··on Yi Peng 3 crossed both cables C-Lion 1 and BSC at times matching when they broke
If a cable goes down, isn't the traffic just re-routed? Don't see the point of intentional damage here.
rafinha··on Trump wins presidency for second time
That "enough of the damn emails" moment from Bernie Sanders during the democratic debate was very weird to say the least. It seemed he wasnt interested at all at moving forward with the nomination.
rafinha··on Show HN: I made a digital circuit drawing and simulation game
That looks cool, I'll take a look thanks! I've been studying how to implement blueprints+layers, that might give some good clues indeed, thanks!
rafinha··on Show HN: I made a digital circuit drawing and simulation game
You're right, I'll put better instructions this week. In the message you sent it seems to be a git submodule initialization thing.
rafinha··on Show HN: I made a digital circuit drawing and simulation game
I haven't thought of that. It might be cool to add something like that for some extra puzzle/optimisation element. I guess it might be useful for netlist export? thanks
rafinha··on Show HN: I made a digital circuit drawing and simulation game
I'm glad you liked it :) . That's a good idea for the colors, I'll put it in, thanks! You're also right about the trailer, I'll put it there.
rafinha··on DensePose: Dense Human Pose Estimation in the Wild
This looks so cool! I wonder if they'll make training data available
rafinha··on Big Tech Is Going After Health Care
Not necessarily. You can still provide decent services collecting anonymized data.
rafinha··on Hybridizer: High-Performance C# on GPUs
For "easy gpu programming" look for tensorflow or any of these "run on CPU and GPU" libraries. For anything else there's no magic, need to write kernel code and take care of memory layout.
rafinha··on Relicensing React, Jest, Flow, and Immutable.js
caffe2, proxygen
rafinha··on Amazon EC2 Elastic GPUs for Windows
Isn't there latency problems if you render your game on the cloud? I mean, you need to move the frame from Amazon GPU to your GPU I suppose.
rafinha··on Dangers of Sitting
you have to work from bed, as I'm doing now :)
rafinha··on Amazon data science interview questions
I have mixed feelings concerning this methodology. At the same time I feel I'm a bit rust on the details of the field, I still believe best way to assess academic background is by sending a paper "offline" and asking the interviewee to explain it. IMO all these quick-answer questions asses is how prepared is the interviewee in answering quick-answer questions.
rafinha··on Explaining React's license
Yes, just like he mentioned for the other projects. It even has the PATENTS file added to it: https://github.com/caffe2/caffe2/blob/master/PATENTS

Caffe and Caffe2 is also a good example!
rafinha··on OpenAI at the Dota 2 World Championships
All these fancy stuff and valve still can't detect people feeding chicken...
rafinha··on Build2 – A C++ Build Toolchain and Package Manager
Well I think exactly the opposite. In C++ it's a nightmare to build a prototype with a new library. You spend a huge time setting up the build system for that particular library, need to figure out how to plug into your code, fix dependencies (which in practice always have something broke/missing). That being, I think a propper package manager would add value to c++ dev,
rafinha··on U.S. Launches over 50 Missiles at Syrian Military Base
"Trump knows this" is a strong statement.
rafinha··on Ask HN: What medical datasets do you need?
I'm not sure such thing exists: "large companies with lots of medical data". Medical data is often confidential and belong to hospitals.
