- Comment on YSK that you can create keyboard shortcuts to adjust brightness and contrast of your computer monitors even on a desktop PC 4 days ago:
Not as of a year or so back. I’m not sure how it works but there are several settings available in the manufacturer’s app that are not in Linux. Only the hotkey settings from the fn+ function keys work. Dmesg spits out a block of unrecognized memory that is something like 8 or 16 bits long that is the likely culprit. There is some odd microcontroller on a serial bus that is unrecognized too IIRC but that I have never seen before like any of the thousands found on LCSC. Last time I checked linux-hardware.org, it looked like no one had solved this one on any of the scans. I’m not motivated to chase it down myself. Poking some registers or watching for the changed location after using the built in hotkey would be peripherally interesting as a general thing to know.

How does one find an unknown register in hardware for a similar but undocumented setting? My laptop has an undocumented microcontroller for the RGB keyboard. I can change it through the extra function keys but only to a 3 level preset and not the real fine tuned control. I can dual boot and change the setting with their app and it is persistent. If I could discover all registers their app uses I would totally ditch w11 and free up a good bit of space. I figure it is just a block of memory somewhere, (thinking like Arduino stuff), but I am clueless about how to find that at OS level complexity… If anyone here casually knows at a conversational social level here, like don’t go looking it up for me or whatnot

This is a 2.4 GHz directional WiFi antenna. Only the back element is connected to the transceiver. All of the other elements are there to focus the signal. Anything metallic within a few feet of an antenna will have a substantial effect on the signal. Think of it as light, because it is, only transparency of materials is a bit weird. The biggest issues will come from metallic materials that are earth grounded and anything with a wire length that is close to the wavelength of the radio light or below, especially around half and a quarter of the wavelength. That pictured wire pitch is spaced very close to the approximate 2.4 GHz wave length. For example most antenna are an insulated trace on a circuit board that is insulated with ground up to a point and then there is a small circuit element that stops the ground and the actual antenna trace continues for the respective light wavelength to transmit or receive. All an antenna is here is an exposed length of single conductor wire.
- Comment on New God tier filament for me 5 days ago:
Who responds to a general skepticism as a personal insult while having no substantive material or value in reply and projects further onto absolutely unfounded and unrelated nonsense in a rant. That was remarkably pathetic and quite disappointing to see from any human. I expect you to act exactly like in real life and if you said this to my face, I’d call you a stupid asshole too.

- Comment on New God tier filament for me 6 days ago:
Totally paranoia fueled here, but I’m thinking along the lines of extrapolating ‘extraordinary claims require extraordinary evidence’ into the practical applications space of ‘extraordinary material properties that deviate substantially from baseline must have extraordinary compromises elsewhere.’
You know, like the saying, ‘pick any two engineering targets of three: Good, Cheap, Fast’.
The materials are not magic, so why was this not some baseline for all of these years. Why is it when the world is deregulating and accountability for exploitation and criminality are none existent, suddenly some miracle chemistry product comes along?
As stated, this is probably unfounded paranoia and is entirely baseless speculation. However, I think the prudent course as consumers in the present is to be extraordinarily skeptical of all new products. I want to know exactly what additives and base materials are used, what volatile organic compounds these create at all printing temperatures and well beyond. There is poor actual thermal coupling and feedback between a thermistor and the real melt chamber temperature gradient. The thermistor is only measuring a block’s temp with heat dissipation and averaging, not the cartridge temperature or hottest point in the melt zone. So what happens at higher temps than recommendations is important to know especially with high speed printing where the extrusion is pulling most heat out of the block but super inconsistently for PID control loop stability.
I think about Tetraethyllead in gasoline as the standard of chemistry in capitalism. It was the miracle property enhancer solution to stabilize combustion to avoid premature detonation at the cost of harming every human alive.
Whatever is in these products is in the air inside your home. We live in primitive times where biology is only in a precursor stage of discovery and poorly understood. It is not yet an engineering science where humans can wield the power of a complete understanding to create and modify living systems at will. We have never even created life from precursors and reverse engineering a known system.
Until exceptionally transparent disclosure of materials, and testing are provided, (haven’t looked maybe they exist tbh), I’ll stick to older materials that have been somewhat vetted by time and availability with the public as lab rats showing no particularly concerning health issues. For this new stuff, feel free to be the rat in a cage. I’m watching with popcorn ready (sry).

Club night - Comment on Federated 3D print files (Manyfold) 1 week ago:
Love the idea, unfortunately it relies on cdn.jsdelivr.net to work so I won’t use it. It also is trying to access the server: analytics.eu.umami.is to view. I can see the 3dprint.social website, but not any images. I personally never use a website that requires a 3rd party connection to any server that could be accessed by other websites. The standardization of this practice is none of my concern, but it is wrong on many levels of ethics and big picture politics that ultimately impact democracy. Specifically, I may decide to trust your server, but I will never give you agency, real or potential, over me and implicitly trust others as a result of that relationship. Anyways, that is my personal choice, speaking as a user, but as a Mod: also why I’m not going to directly promote this site as it is configured currently. This is no different than my stance on Printables or Thingiverse.

Been saying all along. Climate change is only a population problem from the perspective of the super rich exploiters. When the gov gives up on climate change due to the rich investing in politics, you can count on them having a plan and solution that does not involve the rest of us.
- Comment on Priorities 1 week ago:
It gets really old after 3-5 years and you really start to encounter the unspoken needs like social interaction and the purpose work brings to one’s life. The failures way pretty heavily; far more that you’re likely to expect. A lot of my best ideas and dreams for projects were unexpectedly tied to other chance circumstances that were not present when I had all the time in the world.
Mind you, I am very physically limited, still fully mobile but I can’t hold upright posture to sit up or stand for more than an hour at a time. That has never changed in 11 years, but I am degrading and was slightly more physically capable years ago. I was super capable with my hands before things changed like, painting cars, building engines, high level fabrication, some machining, mig, stick, and tig welding etc. I had to learn new interests like electronics, programming, and 3d printing. Still I have had the unlimited time hack in life, largely in social isolation due to limitations. Lemmy is actually a substantial remedy to this very problem for me.
Anyways, life is about the journey, not the destination, so don’t get too hung up on those dreams of unlimited time. Should you be unlucky enough to experience something like I have, you’ll likely miss what you have now and realize the richness of your present dynamic range of life experience.
- Comment on UPS is bullshit for international shipments 1 week ago:
UPS is for domestic small items only. FedEx is for larger items as they price for dimensions not weight, i.e. shipping a bicycle box or similar is only something to do with FedEx. DHL is your goto for small international so long as it crosses boarders. USPS is also an option. The paperwork to ship will take an order of magnitude longer.
All shipping insurance is a 3rd party scam. Any mistakes are fatal too.
I was a pro eBay’r for a couple of years and knocked down $136k in total gross sales on the platform selling high end bicycle consignments. (It is not a viable business market due to the overhead and sleazy nature of fees structure obfuscation and bad seller services/support. Total overhead for the platform in 2017 with all fees, taxes, and shipping lumped together was never below 39% with a perfect account history. They go to great lengths to prevent you from knowing this number. It takes 3-4 months of meticulous accounting to extract this figure for any given month and close the books on real sales.)
The inability of USPS to reform and improve efficiency to reduce cost is one of our biggest grassroots small business inhibiting atrocities in the USA. It is a massive factor that few people understand or realize. Much of the poor performance of other carriers is due to the outdated and overpriced nature of USPS. Amazon has obliterated retail in the USA because they exploit this incompetent mismanagement of logistics. It goes all the way to terrible government. Like there is absolutely no reason for daily mail in all rural areas.

- Comment on 109 children rescued, 244 arrested in Operation Soteria Shield, exposing widespread child exploitation in North Texas 1 week ago:
I think you’re right in some cases, but also somewhat attributing malice to stupidity. There are primitive people that are far too scared to risk abandoning their mutually exclusive social support network. They exhibit angst at the unknown and unfamiliar and sway in the direction of fight from their fight or flight mechanism. None of this behavior is within the scope of their self awareness. They exist in a fixated cult like state of tribal ignorance and stupidity, and are wholely incapable of curiosity and learning from sources outside the scope of their tribal isolation.
I was this way before my self awareness grew past the point of reflection. My entire family is like this as are my former and abandoned social support network I am now ostracized from as a result.
This is the actual barrier in place that enables cult like isolation and fixation. Meanwhile, these systems are wholly built upon outsourcing ethics to an organization that only wields shame to keep members in line. Shame can never motivate positive action. Shame can only negatively curb behaviors. Without positive feedback, these systems can only produce depression and negative austere conservative people able to cope with the lack of endorphins. It is truly sadistic in nature. Those that are still out of balance are considered undesirable when their cognitive dissonance pushes back in actions the person may not even understand or register.
Religion is largely a cognitive dissonance factory because of these factors. This does not excuse actions that harm others. But it is this antiquated system of subtle harm in the religious tribal structure and its cult like exclusivity of social network isolation that create people with no independent ethics, unable to learn and reason well, and scared of everything outside of their tiny bubble of a life.
- Comment on If you can afford it, PeerTube is having a fundraiser for its mobile app 1 week ago:
Sure, you can send me a nas with drives and another network switch, wiring, and pay for labor to run it, while setting it up to work with my hardware and firewall. I have no interest in these projects to support something maybe useful to you but that I already know. I’d rather just do what I do now and keep it to myself. I’m physically disabled with no meaningful income. Gatekeep your hobby and financial position all you’d like, but **** your random prejudiced negative vitriol towards strangers.
- Comment on If you can afford it, PeerTube is having a fundraiser for its mobile app 1 week ago:
Not necessarily. Like I don’t have my YT stuff stored anywhere any more.
Shorter format stuff – sure, and that seems to be the only focus really for peertube now. Most of the YT stuff I posted was like bits and pieces of my journey of creating a product photography studio and progress I was making while still in my collar with a broken neck. I also made electrical hobby and bicycle stuff. I typically uploaded long format with 20-40 minutes detailing what I tried and what did or did not work when fixing stuff that is supposed to be unserviceable or undocumented and like reverse engineering type content. Some of those proved to be a reference I used many years later. My digital storage has never been at a very high quality level. Most of my motivation is like here on Lemmy; I want to share and just be a little social while maybe providing some useful tidbit that helps someone. I’d rather relegate that digital archiving to someone else mostly because my life has never been well supported or super stable.
- Comment on If you can afford it, PeerTube is having a fundraiser for its mobile app 1 week ago:
We probably need to also get more of us actually uploading to peertube and posting stuff here with better integration.
First step is streamlining account creation and uploading. Is there a post goto for how to sign up? What servers are stable versus maybe not so much? Really useful video content is a major undertaking for technically useful stuff. I did several on YT in the past and some in the hundreds of thousands of views about how to fix or hack stuff where I was the only source posted. Editing something well is at least 1 hour per minute, and twice that with a good setup and recording. So like, I’d be far more bummed if that stuff got lost by instances disappearing. That is probably the biggest hesitation I have had. IMO, useful original content is the holy grail for this kind of thing, or maybe that is just my perspective bias.

- Comment on Bambu Lab Controversy Deepens: Firmware Update Sparks Backlash 2 weeks ago:
Voron carries the original community torch that started all of this with RepRap and Adrian Bowyer. That is not some minor guerilla thing around Voron specifically. It grew out of the era when Prusa started making excuses and doing anti community stuff. Like they are still great, but not for the same reasons that built them. You can’t build Prusa firmware and mod it easily like with a Marlin config or Klipper. And the Mini is a custom hacked Marlin config that looks nothing like Marlin at all. That killed community contributions and the iterative nature of open source. The offshoots and side projects of Voron used to exist around Prusa and were around RepRap before that. Joseph got his start with RepRap selling kits on the side. That is where the MKx nomenclature comes from.
Adrian Bowyer broke what was a stratasys commercial monopoly and singlehandedly built the open source community and entire hobby. If Adrian did not exist, there would be no hobby 3d printing at all. The whole thing is due to this open source project and the community it built. That is why Bambu is hated so much. They are a stratasys like parasite here to exploit and oppress as a capitalist cancer. They are the ultimate type of leopard eating face buy.

- Comment on I made an audio thing 2 weeks ago:
Cheapest Chinese Bluetooth headphones from AliEx around 2019. I think it is an AC6905 chip. The toolchain is rather obscure and piecemeal with write-ups on GitHub and eevblog, but that is beyond my interest. This one was too weak to be useful or one of the audio drivers went out or wire was bad. I have a half dozen of these sports ear buds style headphones that have gone bad over the last decade. Even ones that come from the same brand end up having different boards.
- Comment on I made an audio thing 2 weeks ago:
It does what Bluetooth headphones do but with regular headphones. More usefully, it is a Bluetooth line-output to plug into an amplifier which is what I am actually working on. This will go into an amplifier that can connect to my laptop and is integrated into my bedside laptop stand (I’m physically disabled so in bed most of the time). I’m working on making several parts of my laptop stand more modular. I want this to be removable to use elsewhere if I want and charged when not in use. It therefore has a use, a place of storage, and is always available.
