Probability is easy!
  • Solving this problem is easy, if A or D were correct, P = 0.5, if C or B were correct P = 0.25, since A and D require P = 0.25, and since C and B require P = 0 or 0.5 respectively, there is no correct solution that can be given, therefore the solution is "Undefined".

    Anyway, have a good troll!

  • Pentagon orders AMRAAM missiles worth over $1 billion for Ukraine
  • Well, with Putin suddenly deciding to unveil his newest intercontinental dildos, I doubt even the orange rapey puffball could have stood against the urges of the military industrial complex. This is it folks, we're once again comparing explosive rage boners for sport, what fun!

    Humans are interesting, a little disappointing, but interesting nonetheless...

  • Any gamers on here? What are you playing?
  • Destiny 2 as a F2P user has been surprisingly fun. Yeah, there are paywalls, but there's at-least 60-80 hours that you can play for free with how well the game is designed. Great group PvP and PvE challenges, public group PvE challenges, and over-all gorgeous modeling. Plus the combat mechanics aren't insanely hard to learn, but they can still provide a great challenge. I had my doubts because I've heard it was a microtransaction nightmare, but turns out it's not a pay-to-play scheme like Genshin. I might even buy the expansions and unlock the rest of the game.

  • This is the "food" a 3k per month nursing home serves its residents
  • I juried a case regarding long term care, and I have to say that some businesses definitely treat their patients as numbers. While this is not what happened in the case I juried, I do know that in many states elderly care has gotten so bad that some clinics will intentionally misdiagnose and mistreat elderly patients for no other reason than to keep rooms filled.

  • Lemmy is CEO-proof. After Digg, Reddit and Twitter, that term should be a thing
  • TL;DR: Yeah, I 100% agree, if everyone had a strong safety net, we'd be much better off.

    When it works it works. I mean I have met several people who've expressed a lot of sincere dissatisfaction with the VA's medical services, including limited access to mental healthcare among other things. Particularly of concern is the high degree of veterans who end up on the street--many with severe mental health issues, with some even self-medicating and/or dealing with addictions.

    Of course, I'm sure there are more factors that contribute to homeless veterans than limited accessibility to medical care, mental healthcare, and other social services provided by the VA--but it is important to consider.

    ..and of course, as you are aware, it's better to have those social systems in-place than nothing at all. Even when run to a degree of mediocrity, socialist programs can and do tend to benefit a population. While not everyone may like the Supplemental Security Income and FAFSA programs: without them, I wouldn't be able to attend a university as a future job-seeking student.

    Specifically without SSI, many who are unable to pursue a degree would end up homeless and hungry, becoming a greater burden on society. In my opinion, it's unfortunate that you have to have a disability in order to qualify for this safety-net program; as I know several people who turned to less favorable means of providing for themselves, because they were rock-bottom and didn't qualify for any programs.

    So, yeah, the VA program, and many other programs in the US are great examples of both some of the harms, but also the significant positive benefits that socialist policies can have for a population. Indeed, the greatest harms done by socialist programs in the US seem to be caused by their limitations and inability to properly serve enough people. Providing a everyone access to a solid safety net would do wonders for us as a society and for our economy.

  • Lemmy is CEO-proof. After Digg, Reddit and Twitter, that term should be a thing
  • Not entirely true, I sort of jest when I make hyperbolic statements about socialism being the anti-CEO. I personally believe in mixed economies that are well regulated. I know a lot of people dismiss the successes in Norway and neighboring countries on ideas of "cultural/racial homogeneity" among other things, but they do quite well with a mixed economies.

    In mixed economies, you have both the right and incentive to start a small to medium sized business; and if you become too big and ubiquitous, the government can step-in to help govern your company.

    It's not a perfect solution (I'm not sure if that exists), but I think it's one of the best models we have--and a lot of the governing principles are derived from socialist criticisms of unregulated capitalism. Especially in the US I think we'd benefit from this sort of economic structure; but in-order for that to happen in a meaningful and positive way for the public, we will need electoral reform.

  • Does anyone actually use LibreOffice?
  • I use LibreOffice! Calc, Draw, and Writer are very user friendly once you get used to where the tools are. Impress is a pretty good replacement for Powerpoint: the stock graphics leave a lot to be desired--but that's a simple fix with a good stock image service. About the only thing LO doesn't do is notes, but I'd check out Xournal++ if you were looking for a way to replace OneNote. Plus, LibreOffice doesn't push OneDrive down your throat. It's been a win-win for me.

    Another thing to consider if you really like typesetting is to learn LaTeX: it's a slightly steep learning curve(especially for advanced topics), but it'll do things that your typical WYSIWYG word-processing suite couldn't dream of doing. Plus there are a lot of templates available that you can adapt for your purposes.

  • Four outta five ain't bad...
  • Thanks, that is fascinating, I'm definitely gonna check that out. No microscope yet, but it is on my list of things to obtain, although a proper HEPA filter and fan/motor will come first though, haha! Kind-of wondering if I should switch majors, but I'm already in my 400 series engineering classes--oof.

  • Four outta five ain't bad...
  • Oh, that's a great idea! I'm clearly new to mycology, so I'm just kind-of experimenting--but you're right, we're talking billions of spores, and only two need to meet in order to form a strain. Hmm...

  • Four outta five ain't bad...
  • I used the tip of a specialized tooth-brush, and I dipped it into water and then swiped-up spores from the sample. I wouldn't recommend it though, because it turns out the brush fibers are too stiff and caught on the agar, pulling the plate around. It's probably better just to stick to swabs and use the same method.

    Side thought: a lot of people recommend the z-shape swabbing, but it seems kind-of counterproductive if you're trying to select for the apparent speed and strength of mycelium growth.

  • Fungi seem to 'sweat' to stay cool and scientists don't know why
  • Not to mention the periodic spore clouds, haha! It would be really cool if it were possible though!

    I wonder if it would be possible to get some radiotrophic fungi to absorb IR and UV, so they could functionally act as a thermal barrier, cooling during the summer and heating during the winter...

  • Four outta five ain't bad...

    Day 4 of growing Pleurotus ostreatus cultures from spore. Only one plate got contaminated, but it was bad. There are two contaminant fungi going to battle, and around three possible bacterial colonies. I must have been losing it at the end, haha! Can't wait to see how they progress!

    Adventures in Pleurotus-land
  • Well, for a redneck FFU I would probably just be shooting from the hip--because I'd be building the fan from scratch--meaning it would be easier to build then measure the airflow rate of the custom fan, and then modify the design of the fan or modify the filter size until I get something good.

    As far as resources, this seems to be on-point if you want to just buy the parts outright in a less redneck manner: https://learn.freshcap.com/growing/keeping-it-clean-how-to-design-and-build-a-laminar-flow-hood/

  • Adventures in Pleurotus-land
  • Nice! Yeah, I mostly want it for convenience of working with agar--but the need just isn't there yet. I'm considering a redneck version using one of the 4" thick MERV 12 filters, which are rated to filter 0.3um particles, just not 99.99% of them. I know for a fact it would be much better than my SAB in terms of contamination risk, and I'm considering building my own wooden impeller fan, so if I can scrap an old high RPM motor--I may be able to finagle a basic FFU together for under $50.

    Been working on this one for a hot minute, and I think I'm happy with it!

    Nyandy Beach

    Created this almost half a year ago while experimenting with some fm sounds. Been absent from producing for a little while, but I always come back, because I love storytelling with sounds!

    This is mostly a hobby of mine, but I hope you enjoy!

    Adventures in Pleurotus-land

    From the left to the right (in the attached photo): two jars of Pleurotus ostreatus spores (now mycelium) growing in grain, two jars of P. ostreatus liquid culture cloned from agar, and two jars of Pleurotus pulmonarius liquid culture cloned from agar.

    I also have five agar plates I inoculated with a different collection of P. ostreatus spores, but there's no visible growth yet--so I'll leave those out.

    The P. pulmonarius was cloned from a fruiting body growing on a commercial grower's spent block that was salvaged from their waste pile. It's actually a pretty happy, and fast-growing variety. It seems that it hasn't reached senescence yet.

    The P. ostreatus LC was cloned from a several-generations old sample that was initially from a liquid culture bought through amazon. It hasn't performed super well--which is why I've taken it to spore in two different experiments. I may end up disposing of this LC, but I'll probably store it in the fridge while I work on isolating some new strains from the spore experiments. Hopefully I'll win the P. ostreatus lottery...

    All of this is just done in a simple Still Air Box, it's just a hobby for now. Some day I want to assemble a proper lab with a FFU/LFH, but that day is not today!

    Anyone else culturing anything fun?

    Torsion Hinge Box

    I hope the 3D Printing community welcomes other CNC tools. This is a project I made on my custom-built laser table, utilizing "Living Hinges" aka "Torsion Lattice Hinges". They're a really neat mechanism that allows for a variety of different arrays or "lattices" of shapes that facilitate bending--and of-course these can also be created with an FDM printer as well!

    This particular lattice is a simple design, cut into a 5mm plywood, and the divisions are all 2mm. Due to the length of the torsion pattern and the space between adjacent parts, the lattice featured in this box is actually quite flexible--it's capable of about 180 degrees rotation before risking damage, so for a beveled corner, it works quite well!

    Another cool thing about these lattices is that they are essentially springs! My next project is going to implement a shorter lattice that instead of bending perpendicular to the lattice's plane, will act as a spring along the horizontal axis of the plane. The forces won't be torquing around the vertical columns of the lattice, but rather pressing those columns until the gaps close, so the torque will be along vectors perpendicular to the lattice plane near the thicker connecting regions.

    Over all these are really useful designs, and due to the near infinite ways they can be designed, they can both deform in very unique ways, and also scatter light in very unique ways.

    Hope this has inspired some of you to explore these really cool mechanisms in your own work; and if you have used these before, let me know in the comments!
