Great read. TLDR Shannon's approach to creativity and few mental tools for problem-solving: * simplify by eliminating everything from the problem except the essentials; cut the problem down to size * seek similar known problems,

Just to follow up on the first issue: my laptop has a touch screen. The framework I use (Love2D, which is built on SDL2) can detect this and receives multiple simultaneous touches. In Harmopark the touchscreen is detected, but multi-touch d

Now I've spent some time with harmopark, let me share some thoughts. Experience is somewhat clumsy on laptops without mouse. Maybe in 'select mode' the left click could also toggle selected nodes. On tablet the interface make

I've been down that rabbit hole. Math and music aren't really in such harmony as advertised. Yeah, equal tuning gives your instrument ability to play in any key, but it will always be slightly off. For more enjoyable tuning, your

I solved easy 4, but easy 7 looks impossible. Very addictive puzzle game, BTW. Edit: easy 7 solvable and now my wife is addicted too.

One Night: Ultimate Werewolf is always popular with bigger crowds. It's streamlined version of Mafia game, with convenient phone app that acts as moderator. One match lasts no more than 10 minutes, but no one ever wanted to stop after

Very impressive indeed. I dug around and found his tweet: "uses a neural network I trained on choral pieces to generate the harmonization for your melody" [0] https://twitter.com/daviddotli/status/1075068

Looks and works great. I would put in some control over sustain, without it melodies drown in cacophony. The easiest way would be implementing ASDR envelope where key release triggers R phase.

The article and this video don't describe the same algorithm. As stated at the end of article, "this is not true perlin noise! Hugo's algorithm is not based on gradients like Perlin Noise is. Instead it is what's known a

I actually missed the built-in noise function and instead used the same library you linked to. I tried switching to built-in C++ implementation just now and it was actually slower. The Lua library for simplex does some FFI trickery and avoi

The SDR they talk about in article introduction is specifically using cheap USB TV tuners in combination with open source software to capture various signals. The list of applications is really impressive: https://www.rtl-sdr.com

It's not bad planning, it's about being _first_ on market. Yes there's lots of BS about 5G, but it's still filling the headlines. Also, island-wide field test makes sense before commercially deploying new tech.

I'm also drawing a lot diagrams and the best tool I found is yED. You have to input diagrams manually (no hand sketching), but it's fast and resulting diagram is impressive. Just learn the keyboard shortcuts. For example, with Ctr

Very interesting project. Few questions: Even though flash is memory-mapped, running code from flash will still be order of magnitude slower than executing from RAM. Speaking of which, it would be interesting to know how much of flash is co

Could you point out what the problems were, and what technique did you replace it with?

by veli_joza 8y ago
Here's my take. Back in 80s there was no established concept what video game was supposed to play like, so developers experimented much more than today. Some of those experiments didn't belong to any established genre (Seven Citie

Good for them. They manage to increase revenue without increasing production, and they refuse to be evaluated based on production numbers. Still, 46 million devices just in the last quarter? And investors want it increased?

I remember some 15 years ago when I played few hours of tetris on fastest mode to see if I would be able to learn it. At first the game would last 3 seconds, but I managed to bump it up to some 10 seconds before becoming overwhelmed. It was

IMO the point _should be_ to educate, and not to belittle readers. The list looks very interesting, but it's too terse to take away anything from it.

I'm surprised you feel that way. Lua seems like a perfect choice for pico-8. Its syntax is friendly and concise, and it's maybe simplest language to embed, with tiny footprint. Almost all other languages I know of would be a worse

5ms is bit on the low side. If you're playing from guitar amplifier that's 4 meters from you, you get 12 ms latency just from sound propagation (and most amps introduce additional latency). As extreme example of what the brain can

by veli_joza 8y ago
Completely agree. Hardware itself doesn't introduce any noticeable latency, it's just whole lot of buffers at various software layers because audio stuttering and power consumption is always prioritized over latency. Some devices
