All 3 are brunettes, but look how that little one bounces off the fake blonde's ass

As someone that has learned FreeCAD/slicing/printing and someone that can set feed, speed, and sizzle bacon with a side of chips, I'm not as proficient/experienced with machine tools as I am with design and printing, but for the time I've spent doing both, the total learning curve is about equivalent in my opinion.

See, the thing is, with 3d printing functional stuff, you can't just grab a file and print like this. It sounds plausible in theory, but it is honestly a recipe for a Darwin award when handling tiny explosives (primers technically are) like ammunition for firearms. This can be difficult for many people to grasp, but consumer 3d printers are accurate, but not precision machines. This constraint of accuracy without precision is important. In the most basic explanation, the movements of the printer begin by assuming a 0 (x) and 0 (y) position. All movements assume they are relevant to this 0,0 location and absolute. There is always variance in this 0,0 location.

If you get deep into the weeds, there are also several factors that make every 3d printer's motion system unique to where two files will never print exactly the same between two machines. It does not matter at the tolerances of most parts people share, but this is usually at least 0.1mm-0.5mm tolerances. For something like a gun, or other precision mechanism, you really need a design tolerance of 0.01mm to 0.05mm. This kind of tolerance is beyond the capability of most cheap machines and beyond the kinds of tolerances that can be shared in files with other people and have any kind of relevance. The reason this matters is because the printed parts need to interface with external toleranced parts like the steel barrel. It is very possible to print these parts, but the technique requires skill. One could start scaling a part to try and solve this issue. However, in almost all cases, the X Y and Z axis will have different tolerance ranges that need to be accounted for in the design.

The actual functional way to do this requires designing your own parts. Most people that are sharing stuff like gun prints are really just showing off their chops. A fool might try and just print the stuff, but fools rarely get very far on their own. I might take such a file as a baseline to further play around with in design, but I am far more likely to place the part in FreeCAD and use it as a visual reference only while I rebuild the item from scratch. I can easily dial in 0.01mm tolerances, but I do so in reverse. I print many unit tests and adjust my design measurements until the test prints match my real world measurements. I've spent thousands of hours in CAD learning to design well. I can easily design something like a functioning gun. I do not support others doing so or showing off such content because I think it is irresponsible. This is why the general community consensus, and I banned (real) gun related content from [email protected]. I love functional printing and design at these levels, but the subject of guns is not conducive for a healthy general 3d printing community. Not to mention, it is the kind of thing some foolish kid might try without a full understanding of design, and accuracy versus precision.

Systems like a CNC mill use absolute position motion systems. With these, there is no assumed relative position; if the motion command fails to produce the specified movement there is direct feedback and error handling. Closed loop linear motion systems are far more expensive and/or difficult to realize. These are the basis of any real concern. The ability to print something truly robust enough to function like a gun is a matter of quite skilled learning and practice in the real world.

I find these articles funny. A glock switch can be made out of almost anything from a bit of bent metal sheet to carved wood. 3d printing one is irrelevant. When it comes to guns, the arguments are usually idiotic. I can making nearly anything with a small lathe and mill. The gun problem is a multifaceted cultural problem. Their misuse is largely the result of hopeless disenfranchisement of the poor and average person, along with politically leveraging ignorance and corporate capitalist abuses.

How you doing Squid? Any progress on the food health front?

Right. Natural minimalist makeup/look is WAY hotter than face paint

The undocumented proprietary SoC and Modem. I want complete bit register level documentation of every piece of silicon used.

That is not how real point of sale systems and stores operate in practice. I actually managed a retail chain of bike shops as the Buyer and back office manager. I was the one maintaining the point of sale connections and system. There are always errors in these systems largely due to new and incompetent sales staff that sell/return/enter duplicates of the wrong items. They can enter almost anything wrong, from gender to color, from model year to brand. I've seen them all.

Connecting these systems online is an absolute nightmare. I tried it with shopify, but had to limit the sku's to items I could completely control with minimal intervention from other staff. Generally speaking, the POS system in a local retail store can be more loosely managed where the staff can make up the gaps and mistakes when the POS system numbers do not perfectly match the local stock. If you want to track inventory like is required for online retail, you need a whole different kind of micromanagement and responsibility from staff. You also need something like quarterly inventory audits. These are quite time consuming and are a total loss in the labor time involved.

For online retail to be competitive, the margins with e-tail are absolutely untenable trash for brick and mortar retail. They are not even close. The biggest expenses are the commercial space rent and labor costs. With e-tail, the labor is less skilled, and the space is a cheap warehouse somewhere remote. General retail margins must be 40%+ while e-tail is 15-20%. The two are completely incompatible. This is why real quality brands do not sell e-tail. It has to do with how distribution and preseason wholesale buying works. There is more complexity to this, but overall the two are not compatible. In fact, most high quality brands will not allow most of their products to be listed online except under certain circumstances. This is to keep things fair to all parties and prevent undercutting based on whomever has the lowest overhead cost.

Selling online is only for low end junk and certain circumstances. If you are a high end consumer, you will likely understand this already. It is hard to produce high end goods and distribute them successfully. It takes local Buyers that know their niche market and can do massive preseason spending to collectively give the manufacturer an idea of what they need to produce at what scale. Otherwise, the business will not last long, or they must produce lower end and more reliable/limited products. This strategy will likewise fail due to over saturation of the market segment. It is far more complex than most people realize.

Yeah this has been my experience too. LLMs don't handle project specific code styles too well either. Or when there are several ways of doing things.

Actually, earlier today I was asking a mixtral 8x7b about some bash ideas. I kept getting suggestions to use find and sed commands which I find unreadable and inflexible for my evolving scripts. They are fine for some specific task need, but I'll move to Python before I want to fuss with either.

Anyways, I changed the starting prompt to something like 'Common sense questions and answers with Richard Stallman's AI assistant.' The results were remarkable and interesting on many levels. From the way the answers always terminated without continuing with another question/answer, to a short footnote about the static nature of LLM learning and capabilities, along with much better quality responses in general, the LLM knew how to respond on a much higher level than normal in this specific context. I think it is the combination of Stallman's AI background and bash scripting that are powerful momentum builders here. I tried it on a whim, but it paid dividends and is a keeper of a prompting strategy.

Overall, the way my scripts are collecting relationships in the source code would probably result in a productive chunking strategy for a RAG agent. I don't think an AI would be good at what I'm doing at this stage, but it could use that info. It might even be possible to integrate the scripts as a pseudo database in the LLM model loader code for further prompting.

After my spinal damage from a crash, I can't lay on the hard floor any more. I have bones and muscles shift around in weird ways that seem to stay out of place. In many ways, my chronic issues are like someone that is much older than myself. You're likely to experience similar at some point much later in life, when your body physically needs that extra support to stay in one piece effectively.

That is 100% me. I've had many friends tell me someone was into me but I'm usually oblivious. I never want anyone to feel awkward or intruded upon and basically never act on such opportunities. I would love to, but my mind is usually partitioned off on a half dozen other projects, and at least one big rabbit hole of a curiosity. I have the capacity to shift my attention, but it takes someone being quite forward or otherwise remarkable in ways beyond a casual encounter or simple looks to capture my attention in a way where I might take spontaneous initiative. Basically, every girl I encounter is like my sister on a platonic level unless I have a clear indication otherwise. All my long term relationships are from social encounters with friends of friends where over time I could tell there was clear chemistry. Just saying, if you're a girl, being direct and forward is quite effective with some of us, especially the more quiet types.
