These are basically timing belts for cars. Inside the belt are usually metal or aramid fibers that prevent any elongation of the tooth pitch. A lot of the automotive aftermarket principals of a timing chain versus a timing belt drive apply exactly the same here. The belt lasts longer and operates dry with more accuracy over time.
The positives of a belt drive are maintenance, and that it stays clean so they are most popular with commuters that do not want a dirty pants leg or newbie chain tat. They are only common on heavier bikes like short haul commuters in general and require a “broken frame” that is designed for them in the first place. The lack of transmission gearing means you need to either know exactly what gear ratio you need and deal with only having one speed or you need an internally geared hub. All internally geared hubs have monstrous weight to add. So in practice, you do not find many of these on the market. Even with an e-bike, you still need a geared transmission unless you have throttle control without pedaling.
On the other hand, for a hipster roadie, a fixie with a belt drive is some serious cred. Especially if they can dish it at the local group ride against people on flagship bikes.
That is a spell from Harry Potter and you cannot convince me otherwise
Supporting infrastructure is equally complex. It was the consolidation of so many industries into a global supply chain that only has a few players that makes the present cost effective. The forces at play are far greater than you realize in scope and scale. Your pitching a post civilization dystopia of death and misery. It’s bearings, chemistry, metallurgy, medicine, the list goes on and on.
The future you want will exist a long time from now, but not in the way you imagine it. Biology is the ultimate technology. It is where we are headed a millennia from now. Once the age of scientific discovery is long past and science is nothing more than an engineering corpus, a complete mastery of biology will mean we can create ecosystems with all life and technology existing within elemental cycles balance. At that point, human life will likely simplify in many ways and evolve in others.
Simplification is always regressive and backwards. When complexity seems insurmountable, the solution is to refine and reform. In science, eliminate all the ridiculous names associated. It’s not Maxwell’s equations; they are the magnetic equations. Reform stupid conventions like using the term light speed to mean the speed of causality. We need massive educational reform at all levels accounting for the wellbeing of career educators while also modernizing to account for video recording technology. We need to make housing a fundamental unalienable human right and the exploitation of survival needs like food and housing should have massive consequences.
But no, pushing against complexity is nonsense. It shows you’re naive of the use cases. I recommend you start daily watching Anton Petrov on YT or Odyssey. He covers a white paper research summary daily. You’ll learn many applications of technology and this complexity. Watch Frazier Cain for more depth on present astronomy, and watch Isaac Arthur for a view of what a distant future might look like. Read Asimov’s books like The Caves of Steel and The Naked Sun to see a glimpse of a realistic future.
The world without complexity was only able to feed around 2 billion humans. To suggest that the complexity supporting the modern world is unwanted or unneeded is to kill 6 billion people.
Are you an advocate for authoritarianism and the death of 6 billion humans to achieve the simplicity of the past? The vast majority of goods and trade are for food and the raw materials of life produced in the largest and only areas of the planet capable of sustaining this population.
I come from growing up as a Jehovah’s Witness. (Atheist now). I’m intimately familiar with the blindness of belief systems and how futile they are to fight against. The best way to counter them is by example and drawing people into asking their own questions. Often we need to tell them the questions to ask in such a way that they feel as though they constructed the questions you lead them to ask. Any other form of opposition becomes a fruitless partisan opposition as a foreigner. I’m physically disabled now and my survival pivots on my understanding of this dynamic. This is not hyperbolic.
It is from this perspective that I say, you can’t fix stupid in anyone else. You can only fix yourself and show others what life is like when you do not conform. Like, I rode a bike everywhere until I lost 160 pounds. Several friends and family started riding bikes as a result. I can do anything on Linux and it has caused others to question and try it. I never watch ads for anything and have no subscriptions of any kind, and yet I watch interesting edutainment. Few people understand or are willing to setup a network like mine but still find it interesting that it is possible to live without corporate influences or intrusion, especially when I have no desire to make frivolous purchases like nearly anyone on corporate social media. I think for myself because I am disconnected and that seems to be rare in the present world. I tend to be both a realist and a hopeful futurist.
The way I see it, you don’t make change through authoritarianism or pocket isolationism. You’ll never win the world through a partisan operation or mindset. At best you might win half, but even then, the game is already rigged by the last person that played this hand generations ago. You make real change by living it, talking about it, and making it cool. You’ve got to post and talk about upcycling, about the benefits of riding a bike, about reusing electronics and hacking around, you talk about how you make food without commercial recipes, your fermentation experiments without buying anything, your balcony or window seal gardening with seeds from you food refuse. If you post and talk about these things, you motivate yourself and others to change. When everyone whines at work about their commute, you tell them how great your 6 mile route down the beach was this morning and how there wasn’t a person anywhere around, or you tell them about the mediative value of the hour and forty five minutes it took you to ride 33 miles like you’ve done for the last two years. You might be surprised at how often you find your coworkers joining you on those rides to work as you pass by their merging path from home, I certainly was for those two years before I got a better job closer to my home.
Fighting them only makes you the enemy or opposition, and oppose you they will. If you want to make change, you must show people what is possible, lead by example, travel the harder path but do it in style or just your style. This is my style. The only more direct and effective path is to get a law degree and get into political office… IMO
Ultimately, we are likely on the brink of major change in the next few decades. I think the big one will actually be from M-type asteroid mining. A single object is likely to hold more mineral wealth than everything humanity has accessed since the Holocene began. Dwarfing the wealth of the world will have massive consequences. Earth’s resource scarcities are due to gravitational differentiation (all heavy elements sunk in the center of Earth when it was fully molten). Accessing the core of a differentiated body in near Earth orbit will drive humanity into space in an unprecedented shift of exponential growth and geopolitical upheaval. Wealth disparity will be massive, but the focused pressure and exploration will shift away from the general population. We will just be stuck with the aftermath of the climate change caused by space men. It is likely to be about how the 1920’s were still an era of bicycles steam trains and horse carriages while the 1930’s was the sudden era of the automobile for only slightly above average people. The 2030’s will be the beginning of the space economy and mining colony. It is a much less hyped aspect of the current push into space, but it is the primary unspoken objective if you read between the lines, especially at what Japan has been doing to explore space mining and prospecting… but that is just my big picture hunch about where things are going and why billionaires are kinda acting like doomsday prepers in private and in business… It’s probably a good time to build agrarian skills too tho
To me, culture has more scope. If people refused to waste two hours a day commuting by the mental health disorder of the automobile, we would likely reshape zoning and housing to accommodate the population density required. This is longer term generational culture. It is hard for any of us to take the reigns of such a large scope. Ultimately the comprehensibility is irrelevant to the fact each of us only has one voting wallet. You either accept the way things are or you do not. Only you can change the culture you accept and live within. No one is born into an idealized circumstance that enables them. If you want the democratic freedoms of France you need to build and use a guillotine first. The people that do such a thing were not born into it. I’m not inciting violence. I am citing the magnitude of measurable change. No one is gong to make it easy for you. In this world people will exploit you in every way you are only barely willing to withstand. Ultimately it is impossible to set the bar of how much exploitation and abuse a population can or will withstand. That is not how society works. Governments do the minimum required to satisfy your collective community expectations enough to maintain power only. This minimum governance also involves letting business push people ad far as they can get away with before angering enough people of the wrong class to become a problem. Ultimately, you are the one that decides when to become a problem that gets attention in one way or another. You might try to become the person in power that does the minimum or you might take other avenues. However, your first and easiest vote is with your wallet. If you commit at this level, you will then feel far more motivated and vocal about the changes needed to create an acceptable culture you want to be a part of. You can’t expect anyone to create a better world for you if you’re not looking for one in the first place. The status que is the level of acceptable abuse with that bar set by others. You can’t accept that bar if you want more or anything better.
That article’s perspective sucks IMO. It is not the technology that is the problem in this case. The distance traveled to the meadow on foot versus the suburbs in the car had nothing to do with the technology or lack thereof. The person decided this was the normal they wanted and where they chose to live.
The fact is that this is cultural. You’re willing to work a job that is an hour’s drive away because you choose to take the job.
The one constant with technology is specialization. Things are going to increase in complexity unless civilization collapses. When noticeable shifts happen like with AI, many people groan at the additional burden of change. This has always and will always be the case, especially for people that are overworked and their livelihood put at risk from a technology they do not understand and struggle to learn. AI is especially troublesome because it is extremely complex and difficult to understand just under the surface of the near useless subscription services and basic publicly accessible tools.
Ultimately, the issue is cultural. You must stop working for free and stop treating corporate social media like a form of self promotion. I expect my job description to contractually state what my responsibilities are. If I answer phone calls for anything off the clock, I have a two hour minimum pay for my time. This culture of responsibility without compensation is a massive problem, as is acceptance of “it’s just the way things are” mentality. Unplug from all corporate nonsense and think for yourself. Then push others to do the same. Only take a job that is close by, or move. Find a better job and don’t accept abuse. It is a cultural problem.
Yeah, but it lacks the tree that tends to support more specialization. I still get on the EEVBlog forum from time to time but that kind of concentration of specialization is just not the default.
To replicate that kind of ecosystem I think the platform would need a similar complex branching hierarchy and far more effective utility for searching. The element of time is too prioritized on a link aggregator like Lemmy. Community depth of specialization remains shallow because more intellectual engagement is slower and the mechanics of most recent comment engagement are not effective/implemented. Places like the EEVBlog often have the most engagement on very old threads that also concentrate a ton of history and useful information within the single thread. These threads are the primary anchor for the whole community. I think it would take some novel innovation to bridge a link aggregator’s ADHD with a forum’s depth and utility.
As the kind of noob type to ask dumb questions, I talk out a lot of issues with larger LLM’s now. What I can not, I ask here.
I feel like the forums logins thing is too antiquated. I wish they would all be on the fediverse and compatible with Lemmy. I would love the depth and scope of many forums as niche communities with their own trees of subjects and discussions.
Casting is much harder to access now in many urban settings. I wish I could but have no space for it where I live.
The textured Prusa version is still best IMO, (for a textured sheet). I have one of the textured aliex bronze looking plates and the Prusa PEI film/Textured powder coat/Smooth powder coat. I pretty much only use the textured(s) for PETG. I use glue stick or modge podge 10:1 spray for ASA ABS and PC. Texture is irrelevant with adhesive and adhesive cleans off best from the smooth powder coat sheet. That is my universal go-to. I don’t like printing PETG in general unless I design for it specifically.
You need to watch it carefully. PETG has a lot of trouble with moisture. In practice, it has a lot of trouble with seams. When I print PETG, it is not a passive choice, but is instead built into the design. To be fair I pretty much design everything I ever print. I might prototype in PLA and then print in ABS, ASA, or Polycarbonate, but I will not swap to PETG. With PETG I am designing the orientation and features around seam placement from the very beginning to hide them in the middle of the back faces of a parts where they have 4-10mm to start and establish consistency. If I need a better seam in a tighter area, I make a small curved v-groove like the center inner spine of an open book. This feature can be extremely small so long as the mesh resolution can render it and the slicer also picks it up. The groove and curve will place the seam start and end on the inside of the wall just enough to make the ugliness isolated to a smaller area.
This may at first seem unrelated, but I suspect you might find a similar type of issue where starting seams are not attaching properly and causing a cascade of issues.
The actual underlying mechanism to the seam issue is that PETG is extremely sticky when molten. Moisture will sound like little popping sounds in the extruder and these can push out a tiny bit extra of filament. Even with dried filament, PETG will want to create strings on almost every passing surface that so much as looks at the nozzle the wrong way. When PETG goes stringy, it tends to pull more strongly on the melt zone than any other common filament. This tends to pull out more than the typical wisp of a string and instead pulls a slightly larger bit of the melt zone just outside of the tip. This deviation makes seams difficult to ground consistently.
If you try to just go hotter, you’ll ooze more and the problem will be worse. If you try to z-hop higher, you’ll likely find that the string from the last extrude is just as problematic. You might add more retraction, but you’ll still have the previous issue of the last extruded wisp pulling on the melt zone. If you print in vase mode, the problem will disappear, but that is useless advice. PETG can be extremely consistent in performing badly at the seams. This makes it pretty good for print far production in cases like with Prusa. They can dial in every issue on a layer by layer level and achieve prefect and repeatable parts in PETG. I don’t want to print 500 iterations of my design to dial in perfection, so I only use PETG when I can completely hide the seams in the design and create enough margin to avoid any external ugliness. PETG is awesome because it is the only common filament that will conform to the print plate texture with no visible layer lines. This feature is my primary reason for using PETG.
It is just a hunch, but I bet this is a seam issue.
The abominable billionaire loop makes me happy
Biometrics are passwords you can’t change. Depends on the implementation and hashing, but the digitization of your body is still just a complex number that maths through the ALU in a compare registers operation. That number can be replicated on some level, but you cannot change that number if it is lost.
Other than the attempt to obfuscate the TNI and multi-object bodies, what else have they changed in FreeCAD? I haven’t kept up with it, but have seen stuff in passing like Mangojelly’s titles/thumbnails. I like that I learned the proper old skool CAD ways with the TNI, so I kinda lack much motivation to follow the latest nightlys. I’m not trying to gatekeep or anything. It was deeply frustrating to learn the important ins and outs of the topological naming issue and why all proper design revolves around it. If I stayed informed I’d likely be vocal about how people will (likely) fail to learn why things still break in ways they do not understand even though it is entirely their own fault. So I stay a little distant for now and have done so ever since the real thunder drama. Anything new of note?
All of them except the Prusa. They are all proprietary schemes to get you to subscribe to software. There are hacked sub par tool chains to attempt to use them freely, but no one really does it in practice enough that you see them using the thing regularly.
All high resolution displays are proprietary and completely undocumented publicly. Every display is different in how to communicate with it and they change constantly where reverse engineering one will do nothing of value. The next batch of displays manufactured will change in some fundamental way that means the previous reverse engineering efforts must be redone from scratch. Reverse engineering displays and their protocol is a PITA and usually ruins a display or few. You need complex jigs to handle them outside of their final packaged assembly or things break extremely easily. I’ve messed with some smaller simple graphics and LCD displays and reverse engineering, and it is not fun. So you’re unlikely to ever see one of the proprietary resin printers reverse engineered for use with open source software. So full ownership is not an option. It is basically just like bambu but worse. As far as I’m concerned, the Prusa is the only resin printer for sale because I am not for sale/exploitive manipulation, or renting stuff for a one time payment of an equivalent cost of ownership. The Form Labs stuff is probably the prosumer level go-to.
All phones have orphaned kernels. They are orphans because the source code to run the physical hardware is not available. The manufacturer adds these binaries in the last step of the ROM. They cannot be reverse engineered effectively and every model is different. Reverse engineering one does nothing for the next.
The hacked ROMs are maintained by people that know the kernel source at a crazy deep level. They know both the original kernel that the orphan is based on along with the state of every change and CVE that gets fixed in the current kernel. They are back porting all changes to the old kernel in order to keep it going. Eventually this becomes untenable or they lose interest.
