    Allegedly there are lots of underutilized features in hardware, graphics cards included, due to the lowest common denominator factor and insane rate of hardware change as of late. I don't know a lot about it, but this guy seems to:

    Could be room for optimization in the future as far as software and hardware goes.

    As far as storage, though? Don't know how you optimize that. I'm baffled at how much data there is in general. Alphabet's Youtube content for example: approx. 270,000 hrs of content per day. What the heck does that physically look like?

    Some research studies have suggested that Alzheimer’s disease should also be classified as a type of diabetes, called type 3 diabetes.

    This “type 3 diabetes” is a term proposed to describe the hypothesis that Alzheimer’s disease is caused by a type of insulin resistance and insulin-like growth factor dysfunction that occurs specifically in the brain.

    I've heard (in a commercial mind you) that tinnitus is somehow linked now with Alzheimer's, the claim being that the entire time you're hearing the ringing sound in your ears, your memory centers are being further destroyed—and that the tiunnitus is actually causing the memory loss. No idea how plausible this is, it's just something that might bear some looking into. I suspect the claims are extremely inflated if not completely made up.

    A Google search turned up some results correlating tinnitus (phantom auditory perception) and cognitive impairment, including the following:

    I've had this constant ringing in my ears for as long as I can remember, and my memory is swiss cheese.

    I'm so sorry to hear that. I'm sure you're doing all you're supposed to do to protect your memory - like eat well, sleep well, and get physical exercise.

    Exercise is key. My niece sent me a TikTok video this morning - a doctor saying that research shows a person who smokes but get exercise every day is expected to live longer than someone who doesn't smoke but gets no exercise.
    (lol, why did she send that to me?)

    Of course, we have to remember that correlation isn't causation. I also have nagging ringing in my ears and it becomes very audible soon as the room gets quiet (like when I'm about to go to sleep).

    My entire family from my Dad's side always had hearing problems. My dad is nearly sixty and I really have to raise my voice to be heard. Same story with my Grandmother, who passed away recently. She had bad health problems but her mind was razor sharp.

    But my memory is also swiss cheese. I have to rely on reminders or else I forget.

    Foods help indeed. A healthy diet does wonders in the long-term.

    I love salads. I can live on the green stuff. In fact, sometimes I worry I don't get enough protein.

    I do know the importance of eating well and exercise, trust me. I did both extremely well for a good 5 years, but gradually fell of on the eating and found myself eating a lot of junk food. I'm getting serious about it again. Man, the beginning stages are so tough! But as you develop discipline and your body gets used to it, it does get a lot easier.

    Eggs are a very good source of protein! They're also very, very nutritious.

    But peanut butter is also really good in terms of protein. It is quite fatty but most of those fats are mono-unsaturated!

    Very much so! I have heard eggs described as "nature's perfect food." Loaded with nutrition (all of them except for vit. C) in a little package with only about 80 calories.

    My first PC was a 386 with what was called at the time a Math Coprocessor. I needed it to run a bootleg copy of AutoCAD, one of the first successful vector graphic softwares. I was a college student and couldn't shell out $4k for the 25 1.44mb floppies it came on. I don't feel guilty since I got good enough at it that I produced dozens of skilled users of the product while teaching it at that Technical Institute that Shall Not Be Named. Autodesk should give me a copy. They won't. I have found a lower priced alternate with a very similar, intuitive, UI. GStarCAD.

    I had a budget choice to make. 16mb RAM or a 500mb HDD. I got away with a 250mb HDD. Those early CAD drawings didn't have the processing overhead a lot of it has now. Vector graphics store that data more efficiently than raster, and is easier to process mathematically into all of that fancy 3d stuff. Vector data can be coded with more than just visual data as well, such as physical properties like mass and temperature.

    A 386! Those kinds of machines are my favourite. I have one back in Greece and I plan to upgrade it with a SoundBlaster once I make my way to Greece for the summer. But early Pentiums are cool too.

    I don't think mine has a math co-processor. Maybe I should get one before I go back... although I don't plan on doing anything that requires floating point math.

    Overclocking is something I'm considering too. Gotta source a crystal oscillator!

    There's nothing quite like powering those old machines. It's the closest thing to transporting back in time.

    You sound like a few people I knew who were always souping up their cars, and constantly buying new parts for them. I'd always be laying on garage floors handing them wreches and doohickeys I don't even know what they're called. You know, the cars would have one primered body panel they bought at a junkyard and painted with spray cans, and for weeks at a time the hood was propped against a wall so they could get to the engine better. Fun stuff even if I didn't understand what the heck they were talking about most of the time.

    I have a friend like this, and his car is completely jerry-rigged. He doesn't even bring it to the service-center anymore, even though the "service" light has lit up. He tells me that it's okay and that it doesn't matter. And I believe him since the car runs fine and all... though it is quite the Frankenstein if I do say so myself :D

    I don't know anything about cars but I know lots about computers. I tinker with them all the time and I built a little modem a while back to connect those ancient computers to the Internet. The next tool I want to invest in is an oscilloscope. Those are expensive but very useful! They let you see what the electricity "looks" like.

    Wow, I didn't think anybody was still doing that! It's a lot harder to do now, partly because you have to take your car in for emmisions tests regularly, and if anything isn't standard they pretty much make you replace it with what they think is supposed to be there. They want all work on cars to be done by registered and government-controlled professionals, using nothing but standard approved parts. Plus the engines are all wired into computers now and you need a diagnostic computer to work on them. As I understand it that makes it almost impossible to get junkyard parts and swap them out in your engine or exhaust system. But it was very easy to do up through the 80's or so, and there was a big culture built around it. Movies like American Graffitti and One Lane Blacktop cover it. These guys would cruise around looking for other obviously modified cars and then rev their engines or stop at a parking lot and lift their hoods and talk shop admiringly (or condescendingly), and then race. They all knew where there was a quarter-mile stretch of good straight road nearby to use for a dragstrip.

    I helped my friend get a new hood for his Mustang home from the junkyard, sand it down and primer it, and cut a hole in it to install a hood scoop he had made in shop class from sheet metal, that we called the Doghouse. It was big and boxy and looked kind of weird sitting there on his hood. But it was his pride and joy, he loved it and it was what let everyone know his Mustang wasn't just stock, but that he modified it lovingly and maintained it, like a Jedi with his lightsaber. You could always tell when you'd see another modified car on the road, though some just had replacement fenders or hoods because of an accident, and they couldn't afford to get it painted so they left them either primered or the original color. I haven't seen cars like that in a few decades now. Everything has that new design aesthetic, and they all look completely stock and identical. It's like a switch from the wild west to modern uniform civilization, where individuality and self reliance are strongly frowned upon.

    You're forgetting one important detail: I'm from Greece. Nobody cares about regulations there. The economy is terrible and pretty much everyone drives cars from the early 2000s. The most restrictive thing my friend encountered is the immobilizer unit. Outside of that, he can do anything he wants. He could probably even put a turbocharger in and nobody would still care.

    The same thing is happening in the computer industry and I'm so not into it. A computer used to be very discreet in terms of parts and you could "build" your own. But the more the years pass, the more the parts are being condensed into multi-purpose microchips that simplify overall design. Phones have already gone in that direction. They use a SoC (System-On-a-Chip) in their circuit boards that include the functionalities of many parts that used to be individual.

    That also makes them much harder to fix once they break. And the manufacturers are pushing parts out of the hands of users so they can control the repair market of their own devices. A world where you can't customize and fix your own computer is a sad one... at least for people like me.

    Yeah. One thing has been developing as technology has advanced by leaps and bounds the ability of most people to access the depths of it has gone down. I used to work on cars. I still have a Pentium II running Windows 98, about the last one you could keep running without an internet connection. I have on it a licenced copy of AutoCAD 2001. In the last twenty or more years I have violated that licence five ways to Sunday. It was an educational licence I got. Unlike most educational versions at that time mine was the Instructor's Edition. It had all of the features of the professional version. I haven't used it professionally for quite some time, but use it to design model planes, a lifelong hobby. It is capable of producing files that can be fed to laser cutters to produce precisely fitting parts.

    Modern versions of these programs are bloated by mostly UI fluf. Up until about 2005 I would create design drawings from keyboard commands. I wrote macros using Autodesk's native List Processing language, or .txt script files using ACAD's drawing command structure. You could manipulate drawings by accessing coded properties of things like lines and circles.

    Did I mention I used to teach that stuff? What has happened with cars has gone along similar lines.

    Now we got AI.

    Start planning now for the total solar eclipse of April 8, 2024. The next one after that will be in 2044.

    Not me, but very close to my house in New Hampshire. Or a quick jaunt into Burlington, which is on the way to my sister in Montreal.
