1) My role is the STEM amateur enthusiast, not even a student, nevermind in the professional line. If I were starting fresh, I would gravitate towards that.

2) My enthusiasm for changing to a "sibling server" ranks up there with my interest in changing my email address. Again. Which is to say, "not very," and for the same reasons. I'm not clear I can alter my handle on the Birdsite without losing any means to have my fediverse address in there at all.

3) My wife and the very few friends that started accounts on qoto do not appear to be using this much if at all. "Moving" would for them would sound an awful lot like, "forget you bothered with Mastodon."

4) I'm highly confident any ties between you and any other server will bring on the Ultra Self-Righteous crowd that got qoto on the naughty list, and a new site would be on that list faster than word could get out the site exists.

I accidentally put my VHF/UHF transmission into a long coax cable i had that was disconnected at the far end.... Still got about 4.5 SWR on VHF and about 2.5 SWR on UHF... anyone who says they cant put up an antenna has never tried :) That said I probably wouldnt have gotten much of a signal out.

My VHF APRS beacon has now officially went live again after 2 years! You can track its packets and location here:

@freemo In the immortal words of Miley Cyrus: "everybody make mistakes, everybody has those days...just, preferably not with highly reactive chemical species" 😂

So no one responded to this one, so just wanted to give the answer.

In big-o notation you drop all the terms except for the one of the highest order (the term with the highest exponent).. you do this because the notation is about how things scale to infinity, and as you scale towards infinite only the largest term is significant.

This is the same thing that happens with near and far fields in RF.. the equation that describes the field doesnt make any distinction, its just a long polynomial.. but at close distances (near field) all the terms are significant, so the lower exponent terms are valid, so the near field decays at the rate at which the highest exponent becomes dominant and the lower exponents become insignificant... so near field decays at 1/r^6 while the far-field decays at 1/r^2

Understanding big-O notation is what gave me the revelation to understand why RF far-fields and near-fields exist. Specifically why one occurs over...

I guess Ill reintroduce myself: Hello, S.R. Weaver here.

Im am an Ruby developer, Author, Poet, and Composer. I tried doing game design with RPG Maker VX but could never finish a game.

Ive written seven novels, one poetry collection, and some poetry.

Ive recently gotten back into music #composing, and aspire to play like Claude Debussy and Nobuo Uematsu.

Look forward to meeting people.

@freemo Same. Yea I became dissappointed in the direction eugene was talking Mastodon.

Its weird seeing so many new people,.but Im all for it.

I wasnt expecting myself to get swamped by AI. Not large language models though.

Small Language Models.

@LWFlouisa Havent seen you in years, figured you left the fediverse.. Its wonderful to see you again!

So I was thinking a bit and want to get some input... As you all know QOTO is for anyone in STEM as a professional or with a passion for the topic.

I just had an idea of starting a sister-server, one based on the same principle as QOTO but oriented specifically for students and amateurs as seperate from QOTO, which will remain open to everyone.

This separation can have a few advantages. For starters a new server that will have a new reputation in the fediverse so will have much larger initial reach . But more importantly we can use the main server as sort of a source for mentorship for those on the younger server. I'd like to setup extracurricular servers that might be good to facilitate this and provide learning resources as well as publish more advanced content. Maybe even start a scientific journal or organize a shared blog where all our members can post to as a collective...

I'd love some thoughts.

Welll …
as qoto.org instance admin,
you're working for me, so I stick around.

@Romaq

Please this to help others, thanks!

I offer free tutoring in most college level courses. Can be online, just random questions, video chat, or even in person.

If anyone needs help learning any STEM topic (even you arent in school), please reach out to me I am always happy to help. If I dont know the subject I can also maybe connect you with someone who does, but I am well versed on most of the basics like , and design.

I want to code so bad, but even now as I contemplate a green field project I just cant convince myself its a pragmatic decision...

I really need to find siome way to use this amazingly gun language!

@tatzelbrumm Usually if the interviewee is struggling or stressed I will remind them of this story, that I have had people who couldnt answer a single question that I've hired and that I care more about how they reason their way through a problem than what they know... so hopefully that helps the unequal treatment somewhat.

As for some of the questions I ask, I usually have a range of them from simple, to advanced but most of them are designed to have multiple levels of answers.

Also keep in mind since ive worked in so many diverse fields, usually as the boss, that the questions vary dramatically based on the field. Hiring chemists are very different questions than programmers, or medical doctors, or electrical engineers. So its hard to give you good examples that really covers the gammut.

I think you're a programmer IIRC so let me give you some examples from there:

On the whiteboard, in psuedocode, write for me an algorithm that will check if a number is prime. How would you be able to optimize it if you were asked to generate a bin of primes rather than to test for prime?

What is the difference between little-O, big-O little-omega and big-omega?

How would you evaluate a conventionally written algorithm to determine if it is likely to be suitable for GPU acceleration?

What is the fork-join pattern useful for and why is it so important?

Understanding big-O notation is what gave me the revelation to understand why RF far-fields and near-fields exist. Specifically why one occurs over short distances and the other over long.

Anyone can guess what the connection between the two were for me?

I have been told I give some of the most technically challenging interviews most people have ever experienced.. once a lady couldnt answer any of my questions, even the easy ones, and just started crying.. little did she know she got the job because im not looking for people who know the answers, I'm looking for people who ask the right questions to arrive at and understand the answers.

As a climate scientist who has warned about the threat of climate change for decades, I think the fact that we just saw what was probably the hottest day in recorded history, and probably in thousands of years, is deserving of attention...
