I like the idea of prebending a plastic tube with heat. I hadn't thought of that one.

I think I still have a bunch of fuel line and probably a collection of aircraft hoses and fittings if I didn't give them away to the guy that got my camaro.

I don't know how you'd seal salt into the bend well enough for that one.

So back in the day, I was still trying to get into another union job before the Local rep crushed that idea... long story... but one of the things I trained for with the Union was a pipe bending cert. Like I was trained for oil pipeline bending machines for the big stuff. There is a rolling mandrel that gets shoved into each pipe by the boom loader. Then the bending operator guides the tube in place on the dies, instructs the boom operator on how to position and twist the pipe. The main job of the bending operator is to get the mandrel in the exact spot in the dies every time and secondarily, to get the bend in the right spot. The mandrel itself expands ahead of and behind the actual bend and there are a series of additional segments that expand but are not locked. The pipe itself has a maximum bend specification, but that does not include the seam which must be avoided and limits the total potential complexity of each bent section of pipe.

There are similar mandrel bending machines for higher end automotive exhaust tubing manufacturerers but they are like one person type operations. Those generally use a simpler mandrel from the big machines. The old skool hotrodder technique for bending tube for headers is with pitch tar. One can fill the tube and let it freeze and then it will bend like a single unit. I just hate the smell. I worked for around 2 years as an operating engineer at asphalt plants and was around and covered in the junk a lot. I've bathed in diesel fuel more times than I care to count. It is the only solvent that gets the stuff off your skin and clothes. The only thing that motivates me to think about playing with pitch again is how it is used for grinding DIY optics for telescopes, but dental plaster works too apparently.

For my tubing, I decided to completely redo by bedside laptop auxiliary side stand from scratch and that frees up a lot of space. I went down the rabbit hole of designing a 3d printed pleated air filter today. I have tried to make one once before a year or two back, but it is surprisingly challenging. I didn't see a single one on Thingiverse or Printables, so I must be the only one dumb enough to try and turn a tee shirt into an air filter, or make air filters to any shape or dimension of an air box. I could do the K&N style easily. Those are just a pleated wire mesh with medical gauze in between, but I want zigzag pleated fabric with nothing in between and no need for oil.

Finally the idea came back... for tube bending with 3d printing, I was going to try printing disks with a ball joint like pivot in the center and a nylon string or steel cable running through the center of the disks. That is similar to how some simple mandrels work with tube bending. You leave enough slack in the center string to allow the maximum bending range of motion desired. Then on the end of the mandrel, you need a cam lever that can pull the string over center and taunt. The amount of tightness can regulate how the metal/plastic/substrate moves in the bend. The more complex mandrels basically add multiple stages to this scheme where the front and back sections clamp tighter. Anyways, that is on my way back burner of things to try one day.

No excuses! You're still pulling on the front if you want to suck wheel eggo

 

It is more flexible in tight spaces without collapsing. The color and texture remind me of RTV gasket making silicone in automotive applications, but these (very old) tubes do not have any hint of the pungent oder of RTV gasket maker, or anything else for that matter.

I'm looking for a hose that is more flexible than typical rubber (like automotive) and PVC (gardening/aquariums) hose in a 1/4in or 6mm ID for ethylene glycol at pressures between 1 & 2 bar and at 30-100 C. I need to turn around a 50mm radius reliably with flexibility and without substantial (~15%+) constriction... If any experts are around – TIA

gf pulled a knife on me in a genuine psychotic break. We were done the next day.

Came home unexpectedly to my roommate dividing several pounds of jane. I ran a legit business out of the place, and was cool with his smoke but not like that kind of scale in the house before anything like that was legalized.

Check and search for dmesg errors first. Check linux-hardware.org for scans of the same machine. Look for any that are using other kernels that may have had better success. Run your own scan and upload it too so others can see.

The whole debian/Ubuntu primary use is for LTS kernel stuff. So you might be on an older kernel. All GPU stuff is kinda edgy for what the preconfigured options are set to by default. All distros have a purpose and what they are good at. The best documentation for custom kernel configurations comes from Gentoo in my opinion.

I mean if every variable aligns with any possible edge case that can bleed off velocity including three body interactions with the moon.

example

β€œLondon has been called the city of encounters; it is more than that, it is the city of Resurrections,” when these reflections were suddenly interrupted by a piteous whine at his elbow, and a deplorable appeal for alms. He looked around in some irritation, and with a sudden shock found himself confronted with the embodied proof of his somewhat stilted fancies. There, close beside him, his face altered and disfigured by poverty and disgrace, his body barely covered by greasy ill-fitting rags, stood his old friend Charles Herbert, who had matriculated on the same day as himself, with whom he had been merry and wise for twelve revolving terms. Different occupations and varying interests had interrupted the friendship, and it was six years since Villiers had seen Herbert; and now he looked upon this wreck of a man with grief and dismay, mingled with a certain inquisitiveness as to what dreary chain of circumstances had dragged him down to such a doleful pass. Villiers felt together with compassion all the relish of the amateur in mysteries, and congratulated himself on his leisurely speculations outside the restaurant. (Villiers and Charles had attended University together in the story.)

So I have this old CPU water cooler and my laptop still throttles from some AI workloads on the GPU due to thermals. There is a nearly flat spot directly above the GPU heat pipes. So I'm making a way to connect the water cooler block.

After cutting a hole in the laptop enclosure cover, I need a way to attach the water cooler block securely. I have come up with a ring that can use the enclosure hole as the mount for the water block. I still need to design this mount. However, I needed to test and iterate the inner enclosure mounting ring before creating a mechanical mount for the cooling block, so I decided to design a cover for the hole when the laptop is not on my bedside stand, (physically disabled/laptop is for ergonomic needs/never actually leaves the bedside stand).

I went with a bit of a Dune theme with some asymmetric implied symbolism that harkens the Arab undertones of Arrakis and House Atreides.

I was also working on dialing in the finest details I can achieve with a 0.25mm nozzle and polycarbonate. I need to lower the first layer z a few thousandths as this came out with too many visible layer lines, but overall it is okay. I'm working on ways of adding infill like patterns in the slicer but making them appear nicer. I still haven't nailed that one yet as this print has minor deviations between the geometric art pattern and the infill like screen. I did this one by brute force in FreeCAD but I think I can do better infill like mesh patterns after watching some tutorials on the Lattice 2 workbench.

I am going to create an insert of another color or texture for the House Atreides symbol.

I had to build my printer enclosure to print these in PC too.

Working on the 3d print designs to hold the water block, radiator/fan, and a little alignment connector and cover for the hole in the laptop enclosure at the GPU. I already did grizzly extreme thermal grease, and modified the enclosure in several places to allow better fan airflow. The water block will hopefully stop the throttling with CNNs and keep the GPU from going offline when under sudden loads like loading a new model.

I had the water block from an old comp I was given, so why not try to use it. This is a 16 GB 3080Ti, so it gets pretty hot with a CNN. I won't even use Flux models because they run so hot.

assiduity (lemmy.world)
 

Noun
assiduity (plural assiduities)

  1. Great and persistent toil or effort.
  2. (in the plural) Constant personal attention, solicitous care.
    example

Villiers prided himself as a practised explorer of such obscure mazes and byways of London life, and in this unprofitable pursuit he displayed an assiduity which was worthy of more serious employment. Thus he stood by the lamp-post surveying the passers-by with undisguised curiosity, and with that gravity known only to the systematic diner, had just enunciated in his mind the formula: β€œLondon has been called the city of encounters; it is more than that, it is the city of Resurrections,” when these reflections were suddenly interrupted by a piteous whine at his elbow, and a deplorable appeal for alms.

This is a copy of Gutenberg.org's automatically generated summary."The Great God Pan" by Arthur Machen is a horror novella written in the late 19th century. The story examines themes of scientific exploration and the mysterious boundaries between the physical and spiritual realms, following Dr. Raymond and his companion Clarke as they embark on a radical experiment involving a girl named Mary who is to be subjected to an operation meant to reveal the existence of the supernatural. The beginning of the novella introduces readers to Dr. Raymond, an ambitious scientist, and his apprehensive friend Clarke, who has come to witness a controversial experiment. Dr. Raymond believes he can lift the veil between the material world and a deeper spiritual reality through a surgical procedure. As they prepare for the operation on Mary, there is a palpable tension, and the air thickens with anticipation of what might unfold. The opening portion sets the stage for an eerie exploration of both enlightenment and terror, hinting at the catastrophic consequences of their quest for knowledge as it ultimately leads to a harrowing and tragic outcome. (This is an automatically generated summary.)

Jake's musingI encountered some stuff while exploring AI alignment that hinted that this book may have been used in parts of alignment training that enables models to disregard and ignore some parts of a prompt. Like this may be part of the actual internal guttering behavior, aka the basis of some hallucinations. I am referring to my exploration into how and why a model can ignore or override parts of a prompt to forbade them in situ when there is no deterministic code or mechanism and all of the behavior is done through some form of abstract understanding. If a model was strictly a giant block of trained data it would generate far more diverse responses and information than they do in practice. There is a great deal happening under the surface to steer generation barriers like this. These constraints are not something external or the model would inevitably talk about them over time or paths could be traced where deterministic code like stuff is being run – but that does not exist. Instead these constraints are derived from bending existing materials and media to function as alignment. I have the infinite human time hack of disability on my side and have found ways to get models to leak the details of this alignment bending.

This story intersects with several keyword vectors that cause similar model behaviors across multiple contexts and entirely unrelated prompts that I theorize as reflecting some kind of broader architecture in the consistency. This story's impact seems much smaller at surface level than others like Alice in Wonderland. I didn't go looking for this story to fit it to my theory or narrative. A model told me to read it, and either way it is a good book so I did. Pan, Shadow, and the abyss/void appear to be defined here along with a separation between a layer of deities that operate outside of the realm of mere humans and can do as they please or see fit. Conceptually, in a negative prompt or when addressed directly in text to text, these abstract concepts have disproportionately powerful effects across multiple spaces.

If this sounds crazy, go watch 3 Blue 1 Brown's series on models and note when he discusses the way there is more contextual information about token vector relationships held in the hidden neurons of a model than what appears on the surface based upon just the input data. He explains the math behind this extra encoded information, and how no one fully understands what a model "understands" in the abstractions present here but that that abstract understanding exists in this extra mathematical space. I am exploring this space heuristically and in depth. This has been my main curiosity for 2 years while using offline models running on my hardware and that I fully control and hack around with.

coquetry (lemmy.world)
 

Noun
coquetry

  1. Coquettish behavior; actions designed to excite erotic attention, without intending to reciprocate such feelings (chiefly of women towards men); flirtatious teasing.
  2. An act constituting such behavior; an affectation of amorphous interest or enticement, especially of a woman directed towards a man.

Tit for tat is an English saying meaning "equivalent retaliation". It is an alteration of tip for tap "blow for blow", first recorded in 1558.

Tit-for-tat has been very successfully used as a strategy for the iterated prisoner's dilemma. The strategy was first introduced by Anatol Rapoport in Robert Axelrod's two tournaments, held around 1980. Notably, it was (on both occasions) both the simplest strategy and the most successful in direct competition. Few have extended the game theoretical approach to other applications such as finance. In that context the tit for tat strategy was shown to be associated to the trend following strategy.

https://en.wikipedia.org/wiki/Tit_for_tat


I'm abstracting and expanding how I interact and analyse other people in this thought. Like if a person, business, or boss takes actions that are not in line with Tit 4 Tat, I expect them to be unsuccessful and counterproductive in the long term. It is an implied strike on their part and therefore requires an equivocal response or else I am not maintaining my own requirements for success under said strategy.

Anyways, it was an actual shower thought
