deepnet commented on Learn you Galois fields for great good (2023)   xorvoid.com/galois_fields... · Posted by u/signa11

The problem with algebra teaching is, they just declare a thing without explaining the root reason of why it's there in first place.

Root reason & comp sci application is mentioned near start :

“ Many moons back I was self-learning Galois Fields for some erasure coding theory applications.”

Erasure codes are based on finite fields, e.g. Galois fields.

The author is fraustrated by access to Galois fields for the non-mathematician due to Jargon obscucification.

Also large Application section : “

Applications

The applications and algorithms are staggering. You interact with implementations of abstract algebra everyday: CRC, AES Encryption, Elliptic-Curve Cryptography, Reed-Solomon, Advanced Erasure Codes, Data Hashing/Fingerprinting, Zero-Knowledge Proofs, etc.

Having a solid-background in Galois Fields and Abstract Algebra is a prerequisite for understanding these applications.

I sympathise with your fraustration at math articles.

This is not one of them, it is rich and deep. Xorvoid leads us into difficult theoretic territority but the clarity of exposition is next level - a programmer will grok some of the serious math that underpins our field by reading the OP.

I wonder if the similar molecule Xylitol has the same problem. It seems like so many artificial sweeteners have dangerous health effects, I don't trust any of them. Unless you're diabetic or something, regular sugar seems to be the healthiest choice (in moderation!)

Xylitol is a sugar from birch tree sap.

Yep, the safe assumption with a profile like that is that it's something automated.

Also yes, that's the file size column. Uncompressed left, compressed right. It's a directory but the screenshot doesn't say how many files it contains.

Thank you German is not my strong point

>Because the article is currently down so the summary is all there is for now.

Although ironically this "release" article also seems like an ai summary. Although prose could just be foreign language speaker speaking english.

Ironically, a primary use case for AI will be to summarise AI summaries of articles and CVs.

In a sea of slop…

Judging by the OP's profile, we should be happy that the "AI" managed to recognize a number :)

I am not an LLM [edit] ( as far as I know ;-), but thanks for the profile crit I probably should tidy it up.

Why are you quoting AI slop from reddit? That's an incredibly vague summary of the article about the leaked data and provides no useful information.
deepnet · 5 months ago
Because the article is currently down so the summary is all there is for now.

Yes it provides no extra information but in the [hnews hug of death] of the article it is the only information at the moment

> is easily automated.

At scale, in the backyard not so much. I'm open to being wrong though... got any sources of low scale automation?

deepnet · 8 months ago
Yes !

tl;dr air pump saves turning the heap, insulation keeps heat in, currently Raspi sensing methane, moisture and temp controlling water & air inputs has improved my home hot heap yields 80% and completely automated it - 100% labor free.

The 4 key factors for a hot heap are moisture, temperature and oxygen and green ( high nitrogen ) to brown ( high carbon ) ratio ( approx 2 green to 1 brown by weight ).

I have a 1 cubic metre heap ( the minimum to generate the necessary heat ) and I have an specialised product, a double wall insulated ‘hot’ bin which keeps it working even in winter.

A hot heap steams so water input is necessary.

Hot heaps need oxygen, which is the hard part - manually turning the heap.

The temperature rises to 70 degrees C after a week, which kills all but the extremophile hot heap bacteria which are aerobic rather than the cold heap anaerobic bacteria.

I added an air pump input to the bottom and I have a water hose and sprinkler the top.

I run the air every day for 10 minutes. And the water for when it feels dry.

Now it never smells and composts in 7 weeks instead of 12.

I have now bought a methane, moisture and temperature sensors, electric valve for water and so a RaspberryPi is graphing the sensor inputs and recording the heap water and oxygen timings.

Very importantly, I have a pile to collect greens ( veg and grass ) and a pile for browns ( leaves and cardboard ) so I can fill the hot bin in one go.

Once I get some time I’ll write it up.
