If they choose feudalism, I chose to join (or start) the siege outside their walls. I am a citizen. I refuse to submit to a king or a lord albeit in politics or this anti capitalism move against democracy and an open market. You cannot have citizenship and democracy without the fundamental human right of ownership.

While it is outside of the scope of most people's abilities, the bios is on a flash chip that can be removed, read, and disassembled. I'm no expert here by any stretch. That said, my usual check with software is to simply check for http in strings. Even with a binary like a bios ROM, I can pass it through the $ strings command to look for any addresses. No matter what kind of malicious nonsense the software is doing, it has very low value unless it can dial out.

My lack of a complete understanding in this area is why I use a whitelist firewall for most of my devices. It is also the ultimate ad and tracker blocker as I only visit the places I chose to access. I don't conform to the lowest developer's ethics and will simply stop using any site or service that fails to be direct and transparent.

The thing is, even most whitelist firewalls are inadequate. They only filter incoming packets. That is really an inadequate model in most cases now, especially with local large language models where it is impossible to verify their capabilities. My reason for all thus bla bla bla is to say, a whitelist on a trusted 3rd party device is a PITA but an effective low barrier way to prevent any bad actor from communicating with the questionable device. It still leaves you open to a potential situation where the device could be sending a packet stream to the outside world over something like UDP.

Otherwise, the main thing I would be concerned with, if it is a UEFI device, are the UEFI secure boot keys. Whomever holds these keys has a lower ring access than the operating system kernel. Anything happening in kernel or user space is effectively under their control.

Anyways, the main way to monitor and check the device is a trusted 3rd party router that blocks any unauthorized connections. This can be challenging to setup with something like OpenWRT. There is a forked OpenWRT device running a version that makes a lot of this easier called PC WRT. That can make a whitelist fw a little easier than sorting out NF Tables and scripting a whitelist firewall.

Went out with this girl I really liked but brought a friend too just to make it less one on one and more casual. I really liked her and thought it went well. When I drove my friend home, in conversation, he told me I could do better. It was such a stupid destructive thought. All three of us were into the arts. He was into videography, she was photography, and I was painting airbrushed graphics on motorcycles. I dated her for a little while again later and more seriously, but my life was more of a mess then and it didn't work out. That was one of my biggest mistakes in life; not realizing my lack of emotional depth and letting other's opinions hold sway or weight. I partition my emotions now. I'm not sure how I feel in the moment. My first reaction is likely worthless, so "I'll have to get back to you later" - is my usual response. People who whine about how everyone is about to lose their job at work, or tell me how I should feel about others are like giant red flags telling me to avoid them as toxic. Really, in a way I do not lack emotional depth as much as that part of my inner voice speaks quietly and I need to take the time to listen to it carefully. That girl and life lesson are the same thing to me; an abstracted patch, forever holding that part of my personality. When that red flag flies in my head, she is the one waving it; holding me back; telling me to think it through.

IIRC there was a blog post article in the last year-ish about a researcher at Intel that had been working on using FPGA's for AI. IIRC, they mentioned that the issue they could not overcome was power and scaling. I seem to recall them mentioning that analog had a similar issue with scaling and throughput, but that is the weakest aspect I recall in my abstractions when my main curiosity is why large FPGA's are not the present goto tech.

I'm on the edge of my understanding here, but I think the issue with analog is the depth of tensor rank dimensions. Analog is great and super efficient for the first few dimensions, but AI can have many rank dimensions, and there is no telling what the future of algorithms will hold. Building for optimising the way models work presently is practically guaranteed to result in a useless product by the time it is fabricated and brought to market.

This is insane logic. Like there are killers in prison so all humans are killers type of nonsense. I can go out on the street and give someone a hundred bucks to say absolutely anything on camera. At an individual level, submitting this as proof of anything is psychotic. As far as I'm concerned the criminal gerrymandering corruption is the noise floor. When some asshat can lose the popular vote and still win, you better sure as hell show me evidence of a disparity greater than that percentage of difference. That is the standard of conservative criminality. Your standard. It works both ways buddy. If you can't show multi sourced bipartisan evidence if this scale, you fail your own corrupt standards of voting requirements. You need proof of hundreds of thousands and not some tin foil hatted trailer trash speculative garbage or half baked conspiracy nonsense.

They are a contributing factor in the whole system of gratuity as pay. WH is an interesting niche in that, those that work there generally make decent money, like a good bit better than most fast food joints. It requires people skills, and a crisis management type of multitasking, but often there will only be the minimum required staff in the better run places. It is not too unusual to see a place with only 2-4 people working with a packed restaurant.

The gratuity culture is that you always must tip, but not excessively. However staying past your welcome/meal is not considered acceptable behavior, nor is showing up and not ordering. There are slower WH's in smaller towns where it is more acceptable to hang out when the place is not busy, but these are more like the exception. This is also a place that typically is associated with the idealized single working mom stereotype. You'll often find places where the employee shifts are flexible for these types of circumstances. There is often also some tangible drama to a WH, both from the staff and the customers. There are usually WH's within many residential communities or right on the outskirts. You'll often find the same people present as part of a regular routine. It usually does not involve dangerous culture or violence, but WH is a funny place to go find out and watch the drama of the local community if one is close to where you live.

When I lived in the suburbs of Atlanta, I knew everyone that worked at my local WH and could find out what was going on in the neighborhood based on the collective conversations that happened there. In a WH there is no real privacy or formality. It is one of the few places where striking up a conversation with anyone is acceptable if not expected. You can sit there and be quiet and answer tersely to indicate you just want to be left alone, but that is the exception.

This is part of the southern libertarian republicanism ideal of independent hard work to bootstrap success. This is an illusion that leads to decay and poverty, as time has shown, but is still a core part of southern culture. I'm not saying it is right or wrong. I live in California now. There are no Waffle Houses here because California does not participate in this poverty wage type of exception to ethical pay. Overall, there is no effective alternative to turn to for people on either side, customers or workers. Places like California do not have an equivalent establishment for ultra budget dining 24/7 either. I've lived in both areas long term. I don't know of a good solution.

Waffle House is a chain of restaurants mostly in the Southeast USA. They are almost always open 24/7. It is like a tiny sitting bar with stools and a dozen or so tables. The food is really cheap, the staff is nice, and everything is built around the griddle cook top where all the food is made on the spot. There is no alcohol. This is the goto place to eat if you are by yourself. There is also a strong (poverty) community culture of endearment towards those that work at a WH. Everyone knows the staff basically only get paid in tips. WH is often busiest in the middle of the night when nothing else is open, at least in places like Atlanta, Chattanooga, Huntsville, or Orlando.

I figured out how to remove most of the safeguards from some AI models. I don't feel comfortable sharing that information with anyone. I have come across a few layers of obfuscation to make this type of alteration more difficult to find and sort out. This caused me to realize, a lot of you are likely faced with similar dilemmas of responsibility, gatekeeping, and manipulating others for ethical reasons. How do you feel about this?

Edit: not bait. not loaded. I genuinely want to know how to better visually depict this. Redirect the narrative if you'd like. I am 100% ally, really really. If any toasters come along, we'll toss em in the bathtub. Asking this should be safe in a well adjusted world like here.

I've been messing with advanced Flux generative AI and LLM integration. I came up with this image goofing around for 5 min before shutting down the comp yesterday evening:

TBC: I'm not claiming I can or want to make such a thing, or that there is relevance in such a creation. The passing thought of representative visual humanoids piqued my curiosity. I'm far more interested in the philosophical answers, engagement, behavior, and meta collective awareness that might come from this question, and much more than I care about any image or creation.

tl;dr don't bother. This is too abstracted and nuanced. That is okay to skip.

I like to understand the abstract scope of engineering. This is way beyond the simple surface level, with pics below to illustrate my point.

With electric guitar pickups, the complexity of field shaping and design control over the sensor seems like a place where optimising the profitable manufacturability of the final product remains the primary constraint with little deviation.

I struggle to qualify and quantify my intuitive hunch that there is a whole lot more potential to engineer something new and better within the realm of modern manufacturing. I don't know the principal questions I should ask or what might disprove my ideas from the get go.

  • Most transformers shape the magnetic field far more than guitar pickups.
  • a guitar pickup appears to be more of a two dimensional sensor that picks up the motion of a ferromagnetic string in the two primary directions of motion
  • there are more complex harmonic motions present than a pickup can register in two dimensions
  • the coil and slugs of a pickup are surrounded by a single large winding, yet the strings each have very different frequencies
  • it is now possible to make a powdered ferrite core of nearly any shape and frequency
  • the traditional pickup has little effective shaping of the magnetic field path
  • guitar pickups are not optimised to a point where they are readily used elsewhere in other sensory applications and devices as economy of scale should dictate in an open and manipulation free market... I don't think they are anyways
  • what might be the result if a 270° toroidal powdered core were designed and shaped for each string while tailoring the copper winding and ferrite for each string's mean frequency and shielding each of these
  • would a chord segment gap in a toroidal core pick up more 3d motion from the string
  • what effect would a primary and secondary winding wound in the opposite dot notation direction have on the pickup of more complex harmonics and motion
  • why does none of this matter due to the filtering of LCR and the noise floor or other aspects

Like here is the basic range of commercial products:

The typical schematic of operation:

Basic construction:

This is a typically low noise toroidal transformer that has been around for ages:

Now I need you to abstract this concept with me a little bit. Imagine if a small toroidal core was below each string and offset towards the neck or bridge so that they will fit. Nothing would stick out or surround the string. The 270° is not a radius cut like a pie. Instead it is a chord and removed segment:

There are totally random pics from DDG that are somewhat illustrative in abstract:

These are just some random powdered core ferrites that illustrate how these can be formed into any shape now:

I usually avoid anything audiophile related because it draws out pseudo science nonsense like crazy, but at the center of this question is really a desire for a deeper understanding of sensors and magnetics that have much broader applications in precise motion control and sensors for a range of equipment.

In a higher level of abstraction, I'm also really asking when and where does this subject become the realm of the illusive bearded nude virgin demigods that get enslaved to corpo NDA masters from birth. ^.5^/s

The following is a 14 minute edutainment upload presenting the funicular hanging chain and other techniques of deriving optimal structural compression geometry using the opposite form in pure tension (sounds more complicated than it is), by Architecture and Design Professor Stewart Hicks: https://www.youtube.com/watch?v=iRv_syz2DAc

This is a must watch as it shortcuts math and modeling in useful ways for design with minimal materials. I'm sharing as a 3d printing FreeCAD parts designer that likes to integrate all elements without printed supports in every possible case. The funicular draping chain idea is very much adjacent to how I think about integrating elements into a print design. I have designed with shells that integrate my structural elements, but this upload was an aha moment that takes my empirical design process to a new conceptual level. Modeling structural elements and knowing the math to apply can be challenging, but this kind of principal is a very useful shortcut.

I've been watching some One Marc Fifty stuff on YouTube. I can follow him well, and I'm decent at much of the hardware stuff. At least I can compile OpenWRT or do a basic Gentoo install with a custom kernel. I dread staring at NFTables, but can hack around some. I don't fully understand networking from the abstract fundamentals. Are there any good sources that break down the subject like Ben Eater did with the 8 bit bread board computer, showing all the basic logic, buses, and registers surrounding the Arithmetic Logic Unit? I'm largely looking for a more fundamental perspective on what are the core components of the stack and what elements are limited to niche applications.

I just realized I want to use self signed client certificates between devices. It was one of those moments where I feel dumb for the limited scope of my knowledge about the scale of various problems and solutions.

I'm looking for a place to find any special info on soil nutrients, and simple image comparison type diagnostics. Something like the Wikipedia of a farmer's almanac or something. I'm looking for the best public commons type sources with no ulterior motives or influences; farm nerds for farm nerds.

I'm not looking for copy and paste articles, ads funded nonsense, or anyone that is influenced by sponsorships or product reviews of any kind.

If I have holes in the leaves of my tomato plants, or want to know the ideal lighting conditions, or soil pH, or hydroponics versus potted watering regimes, etc., I want to know where to look for info with everything from basic to advanced academic level depth.

Playing around with the FOSS game Cataclysm DDA, I felt compelled to parse and connect the CPP and JSON to see relationships and complexity. It's the first time I've really felt motivated to do so. I'm just trying to wrap my head around how some features are implemented like z-levels, mining tools and various actions; simple stuff really. I find it challenging to parse something quite this large, so I started scripting a way to track down objects across the code base to see what is defined in JSON and what is hard coded. Normal? Obvious? FOSS alternatives to do this? I'm basically chaining a bunch of grep commands to print pretty trees with bat.

Is all of life a game of showpersonship? (external-content.duckduckgo.com)

I was asking myself what makes for good reading. Perhaps it is relatable acumen, technical prowess, or a philosophically well defined notion brought to sharp focus from beyond the edge of my conscious awareness.

What do you appreciate, about others? Is it ultimately their moments of showpersonship, albeit based on any realm of thought? From kindness to empathy, from technical knowledge to relentless dependability; are all spaces ultimately a platform of performance and success or appreciation correlated with the show one is willing and able to perform?
