in video/image space most code we deal with day to day is still C, lots more rust plugins in gstreamer ecosystem, but 90%+ still C

goeiedaggoeieon Inheritance was invented as a performance hack (2021)

>> People created AbstractFactoryFactoryBuilders not because they wanted to,

I don't think this is accurate. people created factories like this because they were limited by interface bounds in the languages they were coding in and had to swap out behaviour at run or compile time for testing or configuration purposes.

goeiedaggoeieon RustAssistant: Using LLMs to Fix Compilation Errors in Rust Code

I find that these area all pretty bad with more advanced code still, especially once FFI comes into play. Small chunks ok, but even when working with specification (think some ISO standard from video) and working on something simple (eg a small gstreamer rust plugin), it is still not quite there. C(++) same story.

All round however, 10 years ago I would have taken this assistance!

goeiedaggoeieon Healthy soil is the hidden ingredient

our city has no bio waste. we make all our own dried fruit, eat mostly fresh from market (so little to no plastic for our veggies), but an immense amount of organic waste.

goeiedaggoeieon Healthy soil is the hidden ingredient

it allows us to get all our organic and bio plastic waste for a big family with pets, including most bones once we have cooked stock from it, in a compost heap in the city.

we tried composting before and the volume of organic waste we produced was too much and we had to dispose a lot of our waste in general trash (our location has no organic waste disposal that runs in our neighborhood) meant animals ripped our curb side bags open.

I am not a degrowther to save the planet either, so a company putting compostable products in place of plastic ones seems like good economic activity.

goeiedaggoeieon Healthy soil is the hidden ingredient

Space is the main reason. We live in the city and the amount of organic waste we (family of 4 + numerous pets) produce is staggering. additionally meat attracts animals. This I run an overnight cycle and I can add it to my compost heap and let it degrade more and no issues with rodents and other animals who dig through food waste. after using this device, in the future I would always grind/break up my organic waste as fine as possible just to save space.

goeiedaggoeieon Building an AI that watches rugby

if you using CV to track the player, the ball etc from a broadcast it is fine, the scoreboard however not so straight forward. fwiw, doing CV from broadcast for accurate scoring of sports is neigh near impossible due to edges, but human in the loop systems exist. there are also numerous in venue CV systems which auto collect game and player information.

goeiedaggoeieon Healthy soil is the hidden ingredient

great post. I posted in this thread above about using a Lomi to convert our organic waste into organic fertilizer (along with a worm farm), a and cultivating nitrogin fixing bacteria with our outdoor fish pond and a flood and drain system. Soil is great to grow in, if you treat it well.

goeiedaggoeieon Healthy soil is the hidden ingredient

We use a Lomi to convert our organic waste into compost I can add to my worm farm

and then from the worm farm, mix with outdoor soil and grow in that. A automated a flood and drain system with our fish and cultivate nitrogen fixing bacteria with that, and water the plants with this water every couple of days.

Using these two approaches I have not had to buy any nutrients in years and our soil is doing well.

goeiedaggoeieon Building an AI that watches rugby

I think you misunderstand that case "compiled its scores and statistics by employing people to listen or watch the games, then enter the scores on the computer which transmits the scores to STATS' on-line service, to be sent out to anyone using a SportsTrax pager.[1]"

Notice how they watched the game and got the statistics like that. The restrictions are about using the scoreboard and the data displays and reselling/commercialising that data. It is however legal to watch the game and compile and distribute your own stats due to the game entering public domain.

Due to this many betting companies and data collection companies have to pay people to watch the game vs just scraping the scoreboard (which is the context from which I learnt about this). ironically at venue OCR is a common way to get scoreboard data.

goeiedaggoeieon Building an AI that watches rugby

Reading the scoreboard from a TV screen and selling that data is restricted in many jurisdictions. This work is pretty naive I think.

goeiedaggoeieon We asked camera companies why their RAW formats are all different and confusing

Things like camera intrinsics and extrinsics are not fixed. 1000 bytes seems small to me given the amount of processing in modern cameras to create a raw image. I could easily imagine storing more information like focus point, other potential focus points with weights as part of the image for easier user on device editing.

goeiedaggoeieon HTTP/3 is everywhere but nowhere

As an Akamai user I already serve all my DASH traffic (video) over http3. Akamai itself return to origin only supports http 1.1 LL-HLS forces me use HTTP2.

The problem here is Akamai really in only supporting HTTP1.1 to the origin. Cloudfare I think only supports HTTP2 to origin. Does Fastly yet support QUIC to origin? Does Cloudfront, I could only find information about it supporting QUIC the last mile.

Maybe more CDN support will drive web server support.

Yes, conductivity is pretty useless over time.

more tricky frequently because you need to measure the moisture for each plant as maintainance is difficult without, but this is generally the most efficient low cost method in very arid regions from what I have seen (dad is prof in the field, so exposure is years of unpaid labour as a child and student)

goeiedaggoeieon Open Source Farming Robot

you don't need anything fancy for drip, a small hole in the pipe and a timer on your pump is is generally enough. If you really want to go fancy you can isolate the system and use moisture sensors, which are cheap.

goeiedaggoeieon POV-Ray – The Persistence of Vision Raytracer (2021)

pricing is the exercise of determining value, even in a non monetary economy (think barter or contribution) you still need to price the value of materials and time. obviously money creates secondary effects which are not related to value due to arbitrages and other effects, but I do not believe you can have finite resources without determining value, which is what I meant by pricing.

A key problem with unfettered capitalism is the tragedy of the commons. If left alone rogue/selfish actors will destroy that which belongs to all of us and is required to live (see nature). How do you propose to solve this without "benign" interference?

goeiedaggoeieon POV-Ray – The Persistence of Vision Raytracer (2021)

even if we restructure everything to meet human basic needs, pricing will still be part of the equation. finite resources means value has to be attached to materials.
