emadehsanon “Open source” seeds loosen Big Ag’s grip on farmers

> The farmers saved a percentage of the seeds and sowed them again the next spring. However, this is not a lucrative model for profit-oriented multinational companies, since the seed breeders only earn a profit during the first sale and not again every year.

Was the "inability of the produced seeds to be sowed again and turn into a crop" intentionally baked into the seeds sold by these companies, purely for profits?

Or was there a genuine biological / physical limiting factor? E.g. crop will be more susceptible to pests?

I'm trying to avoid that if I could automate that typing process and just do voice over to explain the code.

This is a good idea. Thank you for mentioning

On a side note, Observable is stupendous. Interactive Network Graphs, Charts, Maps, Animations. Not sure why we don't see it used enough.

emadehsanon DALL-E Chess in Jungle and Dunes

Most inputs were a combination from these:

"Painting/Digital Art/3D Render] of [Animals/Foxes/Monkeys] playing Chess in [Jungle/Dune/Desert]"

Some inputs were specific: "Capaybara vs Groundhog Chess match" or "Llama vs Panda/Red Panda in chess match"

I almost used all the credits OpenAI gave me for DALL-E. This set consists of about 50-60% of all the images I generated.

emadehsanon Show HN: Pipes puzzle (a.k.a. Net) on a hexagonal grid

You are right. It is possible that branches (pipes) cut from one Spanning Tree might be re-arrangeable into a different Spanning Tree.

emadehsanon Show HN: Pipes puzzle (a.k.a. Net) on a hexagonal grid

My understanding is that since the game mentions:

"Rotate the tiles so that all pipes are connected with no loops."

These is exactly what a Spanning Tree is. So, any spanning tree generation algorithm would do. You just generate a random ST each time and cut this tree where the hexagon borders intersect with it (to get pipe pieces) and randomize their orientation.

These algorithms are not going to disappoint you in terms of performance.

I made tutorials on the topic as well. Might help me clear my point: https://youtu.be/d5yzKkG1n1U?t=36

Apologies for spamming. Sorry, if I'm suggesting premature optimization.

emadehsanon Show HN: Pipes puzzle (a.k.a. Net) on a hexagonal grid

I see. Amazing work you have done! This game is enticing.

emadehsanon Show HN: Pipes puzzle (a.k.a. Net) on a hexagonal grid

if the pipes are cut from a Spanning Tree connecting all the hexagons (like the one you witness once you have solved), then yes, for those give pipe pieces, there should be only one solution.

emadehsanon Show HN: Pipes puzzle (a.k.a. Net) on a hexagonal grid

Captivating! So, while generating the puzzle, you are essentially creating a random Spanning Tree for the given nodes (hexagon) arrangement? Then you randomize each pipe piece's direction within a hexagon?

What algorithm are you using for it Spanning Tree?

I have been working on Maze Generation[0] and found randomized Prim's, Kruskal's to be useful for Spanning Tree creation but the good old Depth First Search increases the difficulty of solving a Maze.

Sports are not regarded as intellectually fulfilling but these channels would change your perspective on how much Technique and Game Planning is involved at the highest level:

emadehsanon Ask HN: How far could you get Coding without Google?

web is so saturated, it is hard to turn off the internet if you want to put some distraction free hours of coding. There will be something you don't know

My guess is that OS programming (Linux etc) has not been affected that much form this overflow of redundent tools and you can stay productive offline?

emadehsanon Ask HN: How far could you get Coding without Google?

Very interesting. I'm curious that what software did you build or maintain? :)

emadehsanon OpenDroneMap

What are some algorithms involved in building a project like this?

emadehsanon Ask HN: I always beat the technical interview but never get the job. Why?

Ask for their feedback. In the meantime, treat the variables for your rejection as "Unknown unknowns". You don't even know what you don't know.

To find out, work on an interesting project. Build something that involves the whole tech stack you are targeting. You will actually find a lot of gaps in your knowledge. The idea should be something that you care about... that will keep you interested in seeing the final outcome if it is a large project.

You have to showcase your ability to work on large sophisticated projects and the confidence that you can get them done.

emadehsanon Show HN: Why I started another Public Volunteer Computing project?

Each inference takes about 110 ms in chrome on a core i3. And memory consumption is ~ about a tab with Facebook open.

Of course a native client would be much efficient considering Tensorflow.js runs over WebGL on top of browser.

What do you suggest for the name?
