  • I do audiology research and can tell you right now, short of a cochlear implant -no we can’t. And we are easily about two decades away from anything close. And even then, a CI can’t make music sound as good as your ears. There is no ‘one’ place in the brain you can imput music into. The most dense and easiest place to input the music is in the cochlea, like a cochlear implant does. Every place up the chain then branches out to thousands of connections and makes it harder and harder. And every step higher up that you try to interface into means you are skipping the initial signal generator and lose out on all the needed fidelity. The next step above a CI is an ABI, auditory brainstem inplant. And they sound so bad, just going one stop up from the cochlea, that those users barely can understand speech and only in the best settings. And normally after about a year of auditory therapy with it. Realistically we tell people (the handfull a year who will end up with one) that they should expect to get sound awareness, and that’s it, from their ABI. And now Elon talks about wanting to go another half dozen steps up from that and magically have the fidelity to make it sound like music?? GTFO. This guy is a moron and doesn’t know what he is talking about.


  • Too soon for Obi Wan? 1977? Nah.

    But I will tell you what was too soon. I was at a firefly/serenity trivia night back in about 2008 or 2009 and everyone had various firefly related cute names. Kaylee’s commandos, the 'Washbucklers, team ‘leaf on the wind’, and such. Then you had the one team that chose fire. Their team name was “Reaver cleaning company: putting spears in the wash since 2005”

    That was too soon…


  • For as much as everyone is saying to buy now out of economic fear, I wouldn’t say they are wrong, but there are several steps that will have to happen first. Tarrifs must be congressional approved first. That means the bill must be presented, debated on, voted on, then signed. I would start to worry a little when we see the bill presented, but even then if he presents some insane ranting that everyone knows will kneecap the economy for the rich, then it won’t go through and I wouldn’t worry. But if he lets his economic hit men write it and it is airtight, targeted, and specifically- then I would be buying my computer parts before the effective date hits for the reasons people are saying.



  • When it is easy bull markets, I go heavy on growth stocks. When the market is bear, I go heavy on dividends. Right now though there is a high beta turmoil, so I have a mix of both. My IRA is also set up as more od a “leave this alone” investment. My etrade account has my “fuck around and find out” money. I mention this because it is hard to directly compare the two. So far my dividends have strongly out performed the growth stocks, but only in the last 3 months or so has the gap widened. I credit it to 2 specific ones that are getting me 30%-ish yields with stable prices. They are also new etf’s, so the hedge money is still strong before the stripping gets to its prices. I mentioned in a post lower that that my little under 30k is netting me 800/month. Honestly it is paying a higher yield than renting out my condo is getting me.




  • Little under 30k in higher risk dividend. Bring in about 800 a month.

    I have a mix of large cap, small cap growth stocks, then dividend high risk and low risk. Stock like this (I do not own PETS, I was just using it as an example) would be a high risk due to its price instability. But you mitigate that with stop loss orders.

    I have a vanguard/roth for my longs (large cap growths and stable dividends with DRIP) and then use etrade for the small cap or high risk ones. I like their tax documents and easy interface.

    People make arguments against dividend stocks, I simply call it a different strategy. Some years it beats out my growths, some years it is about on par. Depends on where I have it at the time and slightly more market dependant.

    I have recently gotten into ex-date chasing. While it has increased the returns, it is more work.




  • $10,000 at 4% gives you $400 interest in one year.

    Just about any decent dividend stock will outperform that. Look at PET for example. It is sitting at $3.65/share right now and offers a quarterly dividend of $0.30. That puts you at $1.20/share per year. 10k = 2739 shares = $3,286.80 dividend payout in one year.

    Banks are the worst place to put investments. Money in bank accounts are only supposed to be there if you need it liquid, like an emergency fund or your checking account.

    For all the nay sayers downvoting me as if it is impossible to find dividend stocks that outperform their precious SPY or high yield savings rates, here is a great list I found with shit loads. I count 60 different stocks that offer 10% yields or more. 100 in total all offering over 8% -double what some bullshit ‘high yield’ savings offers.

  • The grenade thing depends on the generation of grenade. Also depends on the country of origin. Assuming we are talking about the American M67 one you see in most movies, there are 3 different generations of safeties.

    Quick basics of an American grenade- the spoon is the handle looking thing that is sticking out the top and runs along the side. Under it in the head of the grenade is a spring that is always trying to push the spoon off its hinge and make it fly off, while then starting the fuse and the whole bang process. The safety pin (a codder pin with a ring on one side to pull on) runs through the head of the spoon and is held in place simply through binding into its hole/channel by tension provided by the spring. For a little bit of extra safety the end of the pin sticks out about a quarter inch and is bent for a little, but easily straightened and pulled out with the ring (look up a picture and you will see what mean).

    The old ones were just the safety pin held in place by the spring/spoon mechanism. But if you had excessive vibration or just enough pressure and you had pre-straightened the safety for pulling ease, it would negate the spring pressure and the safety pin could slip in and out with ease (thus easy to pull with teeth for Rambo effect). People didn’t trust it, so it was typical to then use electrical tape to hold the spoon down wrapped around the full body and then a bit extra folded back to make a quick pull tab. To throw: pull e-tape, pull pin, throw. The army then added a secondary safety to the safety. It was this secondary safety clip that held the spoon down to the head, providing constant tension and stopping the vibration loosening issues. They were also intentionally designed to have to get pulled off in opposite directions. To throw: (I am left handed) sweep safety clip left, pull pin right, throw. This was in my opinion the best setup and my favorite of grenade generations. Apparently this was about 50/50 with other others. So the army then came out with their third generation, the “confidence” thumb guard thing. It is a metal flap switch that locks/latches the safety clip onto the pin ring. I thought it was dumb. Most people hate it. But credit where credit due- it is impossible to fuck it up. Now to throw: thumb/sweep up on confidence latch, sweep left on safety clip, pull right on pin, throw.

    I am a fan of all good sci-fi, regardless of the time it was made or the limits of the budget. This one is on the list. I will warn others as it has been pointed out- very rape centric plot and story beats. Be sure to watch it with a good level of suspension of disbelief and understanding of the setting. Beyond that, it is one of the best post apocalyptic stories out there and I wish it was redone with more plot, tighter story, and less rape related with the exception of the Topeka plot line. Highly recommend for anyone who enjoys old sci fi or post apoc.



  • Congenital? No. Acquired? Yes. The area of the brain that processes and interprets sound has to develop. Without sound input as a child, that won’t happen.

    Current leading theory of tinnitus is called the ‘central gain’ theory. This is where the brain becomes accustomed to seeing signals from the ear at a certain level, and when that neural level is no longer at that level it will add in its own noise to make up the difference. This noise is then perceived as a tone or sometimes a broadband sound, commonly described as either a ringing or a whooshing sound. Sometimes it can also be described as crickets. Depends on the person and cause. Not all hearing loss comes with tinnitus, but most tinnitus comes with hearing loss. In audiology school we had a whole class on tinnitus and covered many interesting aspects exactly like your shower thought here and went over papers on every angle you could think of. It was fun. But in the end, the brain has to at a minimum know what sound is to even perceive sound.



  • Seriously. We are talking about tire tread compared to weight. Both use multiple sizes of tire depending on the year/model. There are a few that overlap in diameter to get the closest to comparison but they still have a very different width. We are talking about a 235/35R18 vs a 235/75R18. That is a huge difference in wall height/aspect ratio and changes how the tire gives under power. Those numbers massively change depending on model as well. Something like an f150 raptor could have a 315/70R17, almost a foot wide. So comparing just the weight and saying they are close enough is far from a fair comparison.



  • While any aircraft sent to ukrane is nice, I sure hope they aren’t paying much for them. That airframe is about 60 years old with the last major design overhaul in 1990 and its last electronics upgrade in 2000. They would be better off buying F15e’s or even the new f15ex. He’ll, even getting some last Gen f16’s or f18’s over there would be as good or better, but cost probably more. The f15 though is probably the best multiroll jet for the cost.

    Now, if we are talking about sending some OG Mirage 2000 fighters over there, then that sounds like the ultimate white elephant gift France could give. The US could sent some F4 phantoms over while we are at it.

    The big news I the training of 4500 pilots. That is huge. If they could do that, then the mirage 2000 could basically turn into their base fighter trainer and use it as the training wheels to get the new pilots experience and into bigger and better things.


  • You are on a nuke loving platform and people are going to downvote anything that isn’t hard pro nuke. But you are correct. I have had this exact same discussion before. The numbers you are looking for are called the LCOE, or the ‘levelized cost of electricity’ where the lifetime of the technology cost if factored in. Offshore wind is currently the lowest followed by solar. Nuke is clost to 10x the cost. There is even an international nuke consortium that has several reports agreeing with exactly what you are saying and basically sum it up as: if you invested in nuke early, then it is cost efficient to just keep upgrading. If you didn’t invest in it early, then the cost to implement it so high that you are better off going wind/solar. Even if you add in the cost of battery systems, it is still cheaper than building a new nuke plant. And more than that, with these new nuke plants you have to upgrade all your infrastructure because your old wires can’t handle the output loads. If you look at the 30+ billion Georgia spent on this plant, they could have simply given out a micro generation grant to everyone to add solar to their roofs, not needed to upgrade the lines, and been far better off. But hey, just like reddit, if you are commenting on lemmy you better be pro nuke only and ignore the other numbers.
