Starting a second stream on lightweight concurrency in Guile Scheme:

#guile #scheme #fibers #concurrency #lisp
Keep experimenting with fibers and for a good reason I need an operation, which waits until thread is exited.
https://paste.sr.ht/~abcdw/12b2547726c3061f408d3d0f3229408af214cad1
I implemented it and it works, but obviously blows up the memory. I've not finished a "Parallel Concurrent ML" paper and have a very little clue what I do in block-fn, I'll appreaciate if someone can give me a quick solution for now.

"I'm jealous with all the attention 'threads' are getting lately."
- a process, however lowly & otherwise humble
"Me too!"
- a coroutine
"Honestly, same."
- a goroutine
"It me."
- a fiber
"My people!"
- a tasklet
"Represent!"
- a greenlet, looking suspiciously like a fiber and tasklet, but colored green

as a fan of oldskool dystopic/apoc fiction & drama TV (esp from the 60s to 80s, & UK/Euro) let me just say Meta's choice of the Threads name is terrible... & PTSD-inducing
as a decades-long programmer with plenty of scars from doing & seeing multi-threaded programming at scale, well, let me just say Meta's choice of the Threads name is also terrible... & PTSD inducing

#Fibers 1.3.x was released a few days ago:
https://github.com/wingo/fibers/releases/tag/v1.3.0
Moltes gracies @aconchillo!
#Fibers provides synchronous ‘put’ and ‘get’ operations on channels (inherited from Concurrent ML?).
This can be problematic if the sender doesn’t trust the receiver: the receiver can trivially DoS the sender. I wonder how Spritely comrades deal with this? @cwebber @tsyesika @dthompson
This was a hot topic among μkernel designers: https://srl.cs.jhu.edu/courses/600.439/shap03vulnerabilities.pdf
Not just in humans I'll bet...
The Human #Microbiome Is Going Extinct, Scientists Say. The End Will Be Devastating.
by Tim Newcomb, May 19, 2023
"The human microbiome is endangered. And that’s not a good thing for your health—or the health of the rest of the world.
"A new documentary, The Invisible Extinction, highlights how the human microbiome—also known as the bacteria and microorganisms living within the human body, most prevalent in the gut—is on the verge of extinct. And it’s all your fault.
"In a discussion with People, two researchers behind the doc, Martin Glaser and Gloria Dominguez-Bello, say the human microbiome is essential for us to digest food, make vitamins, and train our immune systems. “When we eat,” Blaser tells People, “we are nourishing both our human cells and also our microbial cells.”
"The slow death of the human microbiome is thanks to our modern way of life. We use #antibiotics to kill off bad bacteria. But antibiotics kill off plenty of the good stuff, too. Blaser says the more antibiotics given to a child, the more likely they are to develop a range of illnesses. Blaser adds that the Centers for Disease Control and Prevention (CDC) estimates about one-third of antibiotic prescriptions are unnecessary, leading to the overuse.
"Then there’s the highly #processed, chemical-laden #food that’s wreaking havoc on our gut health. “The single most important component of the diet to feed the microbiome is fiber,” Dominguez-Bello says. These #fibers feed your microbiome, while #ProcessedFood removes the fiber, posing a negative result for your microbiome.
"The researchers want better options for the antibiotic issue, both with improved testing to see if a bacterial infection is really in play, and by developing new antibiotics that don’t have the “collateral damage that are killing every bacterium inside.”
“We are making a complete mess of biodiversity, including microbial,” Dominguez-Bello says. “Microbes are essential in every ecosystem, not only in humans or animals or plants, but also in the oceans. He whole thing is linked together by impact of human activities. We need to preserve microbes because they really modulate functions of Earth. They modulate the climate. They modulate everything. They modulate our own gene expression.”
"The human microbiome is a big deal. Let’s not kill it."

#Fibers are relatively new to #PHP, even though it isn't new to developers of other languages. This is a nicely written overview of this feature:

What exactly is this obsession with "meat substitutes"?
Just don't eat meat
Period
Full stop
You don't need to eat meat, or "meat substitutes"
Eat vegetables, grains, legumes and nuts
Some dairy if you choose

There is one more for this week's #Newstodon:
Meat substitute: a realistic steak made from plant proteins
With a new type of fiber technology, the startup "Project Eaden" imitates the structure of pieces of meat. Visually, the product already looks very real.

The global #sportscomposites market size is estimated to be USD 4.1 billion in 2021 and is projected to reach USD 5.1 billion by 2026, at a CAGR of 4.8% during the forecast period. The demand for #carbon #fibers is very high in carbon frames, golf sticks, and rackets manufacturing due to excellent performance properties such as high strength, good grip, anti-corrosion properties, and lightweight.

@fluepke @herrbett @danimo @buschlabor actually not.
Most subsidized projects are done by #DeutscheGlasfader and even #DTAG is just reselling their #GPON.
Personally, I want dedicaded #fibers like #OM5 & #OS2 (depending on how far away the POP is) and them fed into the building.
#PON / #GPON as #SharedMedia is only better than #DOCSIS in terms of #Energy efficency...

Second part of "Every fiber of my body" - a generative art project created with Blender Geometry Nodes. For the three renderings I used the great procedural materials from Sanctus.

Every fiber of my body - generative art project created with Blender Geometry Nodes. For the head I used a 3D Model from MakeHuman. The seeds of the fibers are distributed randomly over the face and afterwards displaced by a musgrave texture.

Real time B vs A is on average -22% with fibers. +93% without. Spread is -44% lower with fibers vs without.
Fibers are clearly useful even in presence of a faster URI response.
User+sys time are practically the same with and without fibers and so are spread. But represent less than 1% of real time.
