Excrubulent

This is about a bad patent that is preventing slicers from making brick-layer prints that would increase strength enormously, despite the fact that there is clear prior art that has expired for nearly a decade. The patent is full of bad references to the prior art and clearly shouldn't have been approved - even if the person saying it isn't a lawyer, it's obvious.

The new bad patent from 2020 would keep the invention away for another 20 years, and do real harm to the development of 3d printing.

The creator asked viewers to share this with people in the FOSS slicer community. I don't know if that's anyone here, but lemmy is pretty FOSS-happy. Also the FOSS communities here might be interested to hear about how this patent is hamstringing development of FOSS features. I don't have the time right now to search through the communities so any crossposts would be welcome.

Mods, this is self-promo since it's my own video. Please let me know if it crosses the line into ads/spamming, but the main reason I post it here is to contribute content.

it's just better this way

I'm currently paying a moderate amount to atlassian to host jira for me, and I'm looking for a FOSS way to replace it. I don't use it every month and I've decided it's not worth continuing to pay, plus I want to transition to FOSS wherever I can. I just feel trapped. I'm sure people here know the feeling when using proprietary stuff.

I've used hosted bugzilla before, and possibly I didn't know enough about how to make it work, but the web frontend they had was garbage, it was unintuitive and took forever to respond, and I just transitioned to jira because it was easier to use.

I'm happy to self-host for now and maybe pay for hosting if I want to collaborate in the future. I have a Ubuntu server at home with miles of headroom to run a webserver.

I would love to hear anyone's opinions here. Also any other relevant lemmy subs would be very welcome.

Edit: some good questions about my requirements. I'm doing software development on personal projects using git, and I'm tracking issues using jira. I'm also developing hardware, which means 3d print files, CNC files and possibly gerbers for PCBs. All this can be tracked via git, so actually having an in-house way to host all that would be great too.

So I need an issue tracker that syncs with git, essentially.

I have also been using jira to kind of ad-hoc document any research involved in these things, but it's not great because to find any of that documentation I need to dig into my closed issues. I'd like a documentation system that can handle diagrams, drawings and stuff like that, and if this could double as a general note-taking solution I'd love that too, because I've been trying to replace trello/onenote for that.

EDIT 2: Thanks for all the replies. I plan to investigate all the suggestions, my health has just been really bad since I posted this, but I always try to update anyone who offers help.

EDIT: I think this video shows a better design, although I note some improvements below:

Making a DIY analog force sensor under quarantine, with the Kontrol Freak. | KontinuumLAB

The main video linked uses two strips of copper bridged by the velostat, but this creates deadzones where those copper strips are, and probably also gives different responses depending on the shape of the region being pressed. I've done more research and a much more consistent method should be to sandwich the velostat between the two conductors so that the entire surface gives a consistent response that goes directly through the material. This should also give a more pronounced response because the length of the circuit through the velostat is only the thickness of the sheet, not the width of the pad. This should also make it less sensitive to changes in the pad size.

Some videos use conductive fabric, but the best one I found uses adhesive copper tape. If you're getting this, make sure to use copper tape that is conductive on the adhesive side, as not all of them are.

And a follow up video with a more refined method of building the pads and ideas about how to improve the analog-to-digital conversion:

Eight pressure-sensitive Velostat/Linqstat pads for a velocity-sensitive MIDI controller

There is also this method using piezo sensors, but from experience I know that this is completely insensitive to sustained holds. It's used for electronic drumkits because it measures percussion, not pressure:

DIY midi controller with 8 Velocity-Sensitive Drum Pads (on one chip Atmega328) 'Very simple'

I suppose combining a piezo sensor with a simple touch-sensitive control might achieve a good effect, but velostat seems like a simpler solution to me. Also if you want a capacitive sensor on the surface you probably can't use the soft rubbery material that nice MIDI pads use.

Also this guy is quite good at his explanations and breaks down quickly how to make a full button pad, although he still uses regular buttons and pressure-sensitive ones would need a bit more logic to understand:

So I've been looking into how to do this, and I found someone on reddit asking this same question like 3 years ago, and they're still active. I was planning to log in just to link them the video since literally everyone just told them to use regular buttons, but they obviously want to make the real thing, and it's a night and day difference between using velocity sensitive pads and simple buttons. Also they said they live in India where a lot of musicians can't afford the more intuitive interfaces because they're massively marked up, and I thought they should have the information they need to make a DIY solution.

Anyway, I realised giving them that link would be contributing to making reddit the go-to place for information, but I didn't find this there, I don't spend time there, and in fact my alts keep getting banned, and I'm the one adding the information.

So since reddit doesn't want me, I figure the best way to solve this is to make a post here and link them to it. That way I'm helping them with their problem, adding content to the fediverse, and linking people here.

The only thing to add is that I plan to expand on this to make a proper MIDI controller using some of the second video's suggestions for improvements, and I'll be making a modular set of boxes that can magnetise together to arrange however we want. Also I'm going to look for translucent silicone rubber that I can illuminate with RGB LEDs so the sequencing can be animated.

Anyway, if that person or anyone else finds their way here, hello! Welcome, this is a much better place than reddit.

She just happened to catch this meteor and her own reaction to it, entirely by accident. Absolutely watch the video, the shadows playing through the clouds as the meteor passes through the frame are stunning, but the most remarkable thing to me is this moment where laughing with her friends is interrupted and she doesn't yet know where to look. It's such a universal reaction and really special to see. This image is taken as one of the very bright flashes is blowing out the camera. Some frames are almost entirely white, others look much clearer. I chose a frame to make the subject legible but also give a sense of how overwhelmingly bright the flashes really were.

Obviously this man was an important anarchist thinker, but I think this is particularly relevant to anarchism right now in a US election year where this conversation will come up ad nauseum.

He stops short of decrying electoralism in general here, but makes the point that the milquetoast emptiness of the US liberals enables a rightward slide. What he says is short and to the point and avoids getting bogged down in wider issues. He acknowledges that "at least they're not nazis" is an appeal of the liberals, but points out that is the only appeal.

I just think this is a good thing to have if you don't want to type out this argument every time you see it, to point out that this has been happening for a very long time, and to hear a voice of sanity when every single liberal is yelling at you to stop criticising poor Joe or else we'll get the fascists again.

I love how this community knew exactly what to do.

I've recently started getting into parkour and I love its inherently political bent. It reminds of me of Graeber's quote that "Direct action is, ultimately, the defiant insistence on acting as if one is already free," which is exactly how traceurs behave.

This is the lads just showing up to a dilapidated public space and transforming it into a playground. They didn't get permission, they just made the place better.
