Wow. Two years here on #qoto, nearly 2k toots. Always happy to be here @freemo and grateful for this place.
I remember when I decided to try mastodon and signed up on more than one instance to find the rules written in a way that could be used to easily target users restrictively and found users very unfriendly and rude to others with the slightest difference of opinion. Not on qoto. Thanks to everyone here for making this a good place to be.

I think I may have finally finished the Version 2 Schematic of my "Ridiculously Over Engineered SWR meter" or ROES for short.
Its basically an Arduino based SWR meter with an LCD display (not depicted here as that is a seperate shield). But it provides all the functions of a Vector Network Analyzer (VNA) and goes way beyond your typical SWR meter. The only thing it doesn't have that a VNA would have is a function generator, as it relies on the transmitter to do that.
Generally you'd hook a directional coupler into your feedline (I'll be providing that as a seperate kit) and then tie the forward and reflected ports into this shield.

A neat circuit simulation I worked on a while back that was intended to provide automatic RF gain control.
In other words regardless of how strong or weak the input signal is the circuit would either attenuate or amplify the signal to bring it to ~ 3V. The idea was to be able to use it to analyze signals with a wide range of input voltages on a 3.3V chip. It was going to be part of a frequency counter but I created a simpler design for that in the end.
Either way check it out and play with it even if the circuit doesnt interest you as this web-based circuit simulator is pretty cool if your a beginner or just want to mess around with a circuit idea.
@freemo
I agree. It was very bad choice of language on my part, and I appreciate it being pointed out to me.

@Demosthenes @Tel sexual orientation has nothing to do with how masculine you are.
There are really masculine gays while there can be really feminine straight men. Also if it wasn’t the case, there wouldn’t be lesbian trans women.
You can dress all the way you want, but when you say things like : I don’t want to be perceived as gay, you perpetuate negative stereotypes about LGBT people which only ends up hurting them.

A slightly delayed #FollowFriday / #FF I know, but I also don't want to skip this one as we have a lot of new cool people
===== New =====
@louiscouture - A new user from Quebec, his profile reads: I like coding, technology and taking long walks, photography, politics and science. 8values says I’m libertarian socialist but I am just confused and only want a better world for all of us. Do not talk to me about inches and feet unless it’s body parts because I do not understand what it is.
@compass_straight_edge - His interests (that I know of) seem to be #programming and #Math
@svmihar - A gamer and a coder, does some #python.
@EVoCeO From his profile: Hi, new to decentralized social media and social media in general. I chose Mastodon because if its uncensored nature and chose qoto because of its philosophy. Such a fresh take on social media I'm excited to try it out.
@Demosthenes - Also brand new, but has jumped right in and been pretty active since he signed up.
@ml - Seems like an Open-source / #Linux user. He is brand new but gonna keep an eye on him for future posts.

@2ck - From his profile: A capable software engineer and aspirating (sic) cook
@JulianRott - Mostly posts interesting #STEM articles.
@zleap - Interested in #Technology, #Science, Fediverse, Linux and free software.
@lupyuen - One of our embedded / IoT guys, seems to focus a lot on digital hardware and software. Lots of cool projects on his feed, he brands himself as "Techie and Educator in #IoT "
I was only half-listening to a reading of #TheMappist, but I dialed in during the meeting with Corlis. It really connected with a lot in my personal history w.r.t. to #maps, #archiving, and #planning for the future

software licensing long post
Something which I haven't heard about, but which I think is a good idea, is to license free software projects under a strong copyleft license, but add a clause so that it becomes public domain after X years (my preference is 10).
This would have a few advantages. One advantage is that it would be more consistent with my desire to reduce copyright term lengths.
Another advantage is that it would make re-licensing easier, while still being difficult enough that it couldn't be done on a whim. In the worst case everyone could dual-license every new contribution under both the old and new licenses for 10 years, and then 10 years later it would be under the new license. This is just the worst case, though. If you got every contributor for the past Y years to agree to re-license, then you'd only need to wait for 10 minus Y years.
A broad consensus would still be required to re-license the project, so it would still generally be safe from malicious re-licensing, but it would also be easier to fix licensing mistakes (for example, if the project was GPLv2 but the community wanted to switch to GPLv2+). It would also become less risky to experiment with different licenses, because it would be easier to correct the mistake if it became clear it *was* a mistake in the future.
This greater allowance for experimentation would also be useful, I think, because there exist interesting new copyleft licenses which might be a good idea or which might not, like the Parity license.
Technically I've already applied this idea today in some small things I uploaded to github, but they're not projects used by anyone else, so I'm not sure they really count.
Anyway, if anyone is curious, here's a link to the contents of a "LICENSE.txt" file applying this idea, for a project whose last contribution date was in 2019. The idea is that you'd bump up the year in this file each year, so older versions would gradually enter the public domain 10 years after their release. Note that I'm not a lawyer, so I can't actually vouch for this being legally valid.
