They are used for most pairing sequences, but we don't type them in anymore. They are used more to validate that it's you that are connecting two devices.
Honestly, I have never heard of that term before. Regardless, here is a cute pic for you.
(thinks out lound..)
If you could force different speeds and different voltages, you can make some guesses as to what the cable might support.
USB packets use CRC checks, so a bad checksum may indicate a speed or physical problem. (Besides stating the obvious, my point is that doing strict checks for each USB mode gives CRC more value.)
I just looked over the source code for libusb (like I knew what I was looking for, or something) and it seems that some of the driver(?) components hook really deep into the kernel. There might be a way to test specific parts of any type of handshake (for dataflow or voltage negotiation) to isolate specific wires that are bad by the process of elimination.
I think my point is that a top-down approach is likely possible, but it's probabilistic.
Why not? Don't you wish you could detach your hand and send it on its own mission?
Cable testers can bypass all of the standard driver and USB negotiation bullshit before anything else. I would imagine building a device to manually control when and how the connections are made is much easier than fighting for low level device control on systems like Windows, macOS and Android.
I am going to leave it.
Still, you might want to look up the history of your leaders and their opinions on free speech.
I would say your an idiot.

In my case, they keep sending me pictures of my neighbors house. Oh well.
I want to reply to them telling them they should be paying me for my dick pics, but they are either using spoofed emails or compromised Gmail accounts. (They wouldn't care about a reply, even if they go to the trouble of looking for one.)
Seriously, I wish they would at least check my linked in profile first, which is yet another pointless ask because of the automation that is probably involved. I guess they don't want to talk to someone who has been in security for +20 years who's side hobby is wasting email scammers time with virtual machines that are goatse themed. Sigh.
I called that out. It was the weight of the earth.... on earth.
The earth is estimated to "weigh" 13,170,000,000,000,000,000,000,000 pounds. (That is weird when you think about it. The weight of the earth being based on what something weighs on earth, I mean.)
Mt. Everest is only about 357,000,000,000,000 pounds and is just a tiny fraction of the mass of the earth.
So. My point is that we need a better way to portray scale of things in the universe. AUs work to a point but then we have to quickly move to parsecs. Parsecs quickly give way to light years. (Or vice-versa, depending on how you visualize things better.) Light years kinda work, but only for between 14-26 billion years. Even after all of that, I can hardly still fathom the size of Mt. Everest. (This was a rant, but not an angry rant.)
the sound from my sub £100 2.1 soundbar which obviously puts the TV speakers to shame.
Absolutely don't start writing music then. Once you do, it'll destroy your perception of how sound bars simulate 5.1 channel audio. (Most consumer grade Atmos sound bars have a pair of speakers that point up from the center channel to reflect sound off your ceiling. I would be able to hear that "trick", unfortunately.)
My "studio" is super simple and I only use 2.1 audio but with proper monitor speakers that have a mostly "flat" sound. While sound bars are great for limited space, I'll never use one again. For music and most movies, 2.1 is all you need. Rear channels are nice and everything, but kinda pointless in a living room. (If people want a real theater experience at home, good luck buying a proper +30 channel system.)
When it comes time for you to invest in new headphones, buy some ATH-M50x's. Once you hear what relatively flat sound is like, you'll probably end up throwing every other speaker you own in the trash.
Edit: Deleting this post. It's starting to get controversial, but that's OK. Not what I planned on, but whatevers.
I have been attempting to extract the firmware from an HVAC controller board using my Pickit3 and MPLAB X.
It seems that many HVAC controllers are PIC based and most are kind enough to include debug/flash pins. Grabbing the firmware images should be trivial once the correct pins are traced out. MPLAB X will see my Pickit3 and the target MCU, but it fails to pull an image that isn't all zeros. (The "bin" file is a text file with each line noting the start address, followed by 16 byte values.)
I do get an occasional "Target device ID invalid message" but that is usually due to my janky wiring to the board. Once I get that issue cleared, MPLAB will always warn that the debug bit (byte?) is set on the MCU. (That doesn't make sense as the MCU should be running standalone on the board during normal operation.)
Is there some kind of read protection that may be enabled on the PIC? Do I just need to unsolder the PIC and put it in its own dedicated circuit for pulling the firmware?
The one trick that Big Music doesn't want you to know!
I was absolutely struggling when I went to do a final mix after writing everything in stereo. For me, it was a whack-a-mole game: Fixing one problem created ten more, bass was unmanageable, highs tended to blare or everything was a midrange soup and I constantly struggled with frequency cancellation.
Above all other problems, music was not portable. It would sound great with headphones, but became a blown out mess on external speakers.
Mono. Just write everything in mono. If the track sounds good in mono, even just the slightest bit of stereo separation makes it sound awesome!
As a perk, it forced me to learn more about compression and limiting and when it is applicable. If something is inaudible in mono, it's going to sound like absolute garbage in stereo. (It also forced me into EQ'ing nearly every component of a song at first. I am not nearly as aggressive with that now, but again, it opened up new doors that I didn't realize existed.)
Why, oh why, is this technique not pushed more to hobbyists and beginners? Is there a shortcoming that I am not aware of?
Obviously, this isn't a cure-all and I kinda framed this post as a magic trick. Its one hell of a teaching tool, if nothing else.
New system enables faster production, greater optical quality and design flexibility
(Wait, what? This is from 2022??? I have known about CAL for a while, but this glass stuff is new to me.)

CAL: computed axial lithography
Researchers at UC Berkeley have developed a new way to 3D-print glass microstructures that is faster and produces objects with higher optical quality, design flexibility and strength, according to a new study published in the April 15 issue of Science.
I am fed up with resin slicers.
Chitubox is about as stable as a drunk on a tightrope, Lychee is bad for engineering models and over-priced if you just want some basic support functions and PrusaSlicer is under-developed. All of these solutions work for different things based on the goals of the user. (For some, Lychee is an excellent value so my distaste is likely not universal.)
What really pissed me off is that support painting shouldn't be a paid feature. You hold the mouse button down and drop a support at specific distance from the last. It doesn't take massive cloud computational clusters or huge storage requirements but yet, money. Fuck. That.
I want a completely FOSS tool that is stable and includes functionality for auto-positioning models and has a full set of knobs and levers for support generation, support painting included.
So, I spent the morning getting a dev environment setup for PrusaSlicer to use as a base for resin-only tools. Over the next month or so, I'll take some time to strip out all the FDM support and get the slicer into a bare-bones state with only the existing resin features. Of course, it'll be on GitHub.
Back to the main subject. I was hoping that y'all had references in regards to anything resin printing: Support placement methods, model rotation optimization, resin strength data, FEP peel force data or anything that could be coded and implemented into a slicer. Hell, even discovering different methods for hollowing an STL would be nice.
Data and strategies for various tools would be nice to have at this point to at least start forming a roadmap for development. (One of the first goals is to integrate UVTools as a snap-in, somehow.)
FDM tools are plentiful because of wide spread adoption. Resin printers still seem niche so printer manufacturers naturally gravitate to writing their own tools for their own hardware in their race to the bottom.
With all of that said, I am actually curious if others would even want to see a project like this kicked off.
I have been using FL Studio for years. It was easy to pirate when I was younger and broke, and it's still flexible enough for anything I want to do now without hassle. (The license these days is "meh" for clips and plugins. However, I am designing and beginning to record most of my own instruments now with a core set of plugins.)
I would like to experiment with an open source DAW, but not sure which routes to take there.
Spinner shows while thumbnail is being shown after upload and thumbnail is being generated, but not when actually uploading. (I am attempting to attach gif to this post, but not sure if upload has failed, still going or just not possible.)
I am mobile while I am creating this post, so uploads are laggy anyway.
Search is fine, but there have been several cases where I have wanted to manually enter a community name and instance.
Search can be odd at times and being able to have connect at least attempt to jump to a community would be a nice to have.
Edit: I can now post and view cat pics. Yay!
Searching for "cat" or "cats" yields cat@lemmy.world with Connect, but not from web. "cat" is an invalid community.
cats@lemmy.world should be correct community and listed in search results.
A few hours later, I just discovered how long this cheesy noodle trend has been going on for.
Also, this idea was already taken by a previous poster who likely started this trend quite a few days ago, I see.
My mistake!
I am simply on a quest to find an effective non-distillation method for purifying isopropyl alcohol used for rinsing resin 3D prints.
I have seen some elaborate systems for curing and then filtering resin that is suspended in the isopropyl by running it through standard carbon water filters. That just seems a bit over-complex and does a poor job of removing dyes. In some cases, the filters are not fine enough and the isopropyl will eventually get "sticky".
It seems to me that a finer filtration system would work much better. Carbon and celite should catch most of the monomers and oligomers, but I am not sure about the photoinitiators and other additives.
Distillation is obviously the best method for purity, but there may be a worse cleanup and a higher fire hazard risk.
Are there better materials that I could use for filtering besides celite and carbon? IPA is tiny compared to the rest of the molecules I am dealing with so filtration seems viable.
(I should note that I would bulk develop the used IPA in clear plastic containers in the sun for a day or two first.)
Before I get into my comments, I just want to ask that if you haven't bought the dev a coffee, please buy him a coffee. Personally, I have bought several with the intent of covering for those who cannot. Our dev has earned it.
I am just going to say that Connect is awesome. Even through early development, when there were huge issues, it progressed at a good pace. And yeah, it has gotten super stable and functions great as a simple and easy to use Lemmy client.
I would also like to make clear that I respect this app as the sole devs creation. He/She is 100% able to direct this project as they see fit. Period.
However. One person development teams can be a serious risk to the longevity and stability of an app. People get tired and burned out. People have actual lives outside of working on a single app. People can just vanish from dev work. That is all normal.
With the recent Lemmy instance updates and some subtle bugs that are showing, my concern is that it may become a much larger challenge to keep this app up to date. In my limited dev experience, core API changes (or API bugs) are a royal pain in the ass to deal with. A person could spend more time just keeping their app functional instead of developing new features or working on minor bugs.
I was hoping that people in this community that have experience with the development of large open source projects, can contribute ideas for our dev that may make it palatable to open this project up to additional contributors.
I think the biggest things I would like to call out is that if this project is opened, it may damage any revenue that is being generated by this app for the dev and I don't want to see that happen. (People gotta work and people gotta eat. )
What open source licenses are available that would keep full control of this app in the hands of the original dev? (Is that even a viable option?)
Quite simply, other than opening this app up fully, I don't quite know exactly what I am asking for. It would be nice to keep full control of this app in the hands of the dev, while also allowing community development.
Just to reiterate, this post is not meant to be rude or pushy. If anything I said came off that way, it was absolutely not the intent and offer a humble apology if it did.
Edit: Just copy the original filename, Chinese and all, to a custom RERF file. It tested fine with the factory tests and also custom test parts I made. I didn't test with only "R_E_R_F.px6s" as the filename as I proved the original filename works fine with custom models.
Edit2: I had the motivation to check the file today without that Chinese and it works fine as well.
Just got a new Anycubic Photon Mono X 6Ks and the RERF file on the included USB has Chinese characters in the name. ("R_E_R_Fchch.px6s" / ch being Chinese characters...) Does the printer require those characters for custom RERF test prints, or is it actually just "R_E_R_F.px6s"?
The documentation is unclear and online searching is jumbled with several issues regarding this filename across different printer models.
I am business dumb, but I have a very unique mix of skills I would like to turn into a side hustle. Needless to say, there is going to be a huge learning curve for me.
Sure, I could just sell 3D prints on Etsy, but I would rather focus on B2B type work with a more hands on approach than the Chinese print farms/PCB manufacturers. (I'll start an Etsy shop for practice, but that particular market seems extremely saturated.)
So, if you have started a business before, what are some basic things that you wish someone had told you before you did? Are there good books or other references I could use?
Update: Not a Connect issue.
Strange. I don't see this as a pinned post on that community, but yet, there it is. Did an admin pin a post from another instance on .ca somehow or is this a bug with Connect? (Strange things are happening like this since the last Lemmy update. I can't tell if it's a Connect issue, or a Lemmy issue.)
That feed is not /c/cat on lemmy.world, it seems.
I just logged out and logged back in with no change. I'll clear my cache to see if that helps and will update this post if successful.
Edit: Clearing the cache did not help. Must be a Lemmy API issue?
Edit 2: NSFW communities are not hidden in the faux community feed either. Thankfully, they are blurred, but not hidden. Posting a comment with a picture from what was supposed to be lemmy.world/c/world. (Did I use "faux" correctly? I rarely use that word, so hopefully the intent shows.)
Edit 3: Ok, weird. cat on lemmy.world is broken from my account on .ca, but other communities are not, like business on lemmy.world. lemmy on lemmy.ml is also broken. The issue is more random than I thought.
Fenn and Sudo. (Yes. I am nerd and Sudo is "my" kitty.)
I am very much a DIY'er and doing my own HVAC repairs have never been out of the question. Actually, I have rebuilt a couple of systems, less the pressurized parts of the system.
HVACs are great until they aren't and the need for repairs always comes up at the worst possible time. It would be nice to know more details for those reasons.
If you ignore the direct question about charging an HVAC, there could actually be a small, slow leak in my system as it stands. That'll get troubleshot in due time. (Still, I don't think I have ever had a system that didn't need the system to be topped off after a few years, even with no detectable leaks...)
It doesn't seem difficult: Ensure system is at correct temperature; attach a gauge; depressurize/pressurize as needed.
There has to be some "gotchas" in there somewhere. The equipment is cheap enough and I am fairly sure I can source the correct refrigerant easy enough.
Aside from needing to store and manage a small supply of refrigerant and that there are some annoying risks (like a system freezing over, etc..), what cost factor and equipment am I not taking into account?
