  • Harmonic frequencies are more likely to be an issue.

    If you have an antenna transmitting at 2.4ghz, you will also see subharmonic bumps at 1.2ghz, 800mhz, etc. A receiver at 800mhz could potentially get “washed out”, or overpowered, by a 2.4ghz transmitter that is too close simply because of subharmonics.

    Transmitters aren’t perfect either. While you can get really strong transmissions at very specific frequencies that can propagate really far, electronics resonate at many frequencies and that resonance will make it to a TX antenna as noise.

    Unless the antennas are designed to work together, you shouldn’t put them that close together. (I am also speculating that in extreme cases, a weird configuration like that could detune the transmitter antenna in a such a way that it would blow out the transmission circuit. I dunno about that though.)


  • Air, water, AIO, whatever. If it cools well, use it. I just prefer AIOs and there really isn’t any maintenance, was my main point. There are always tradeoffs between AIO, air or a proper water rig, so there is that. (Fans are crazy quiet these days, but when I made the switch, it was mainly for noise. I always run an overclock, so my fans were always hauling ass which probably isn’t needed now.)

    Ultimately, I prefer AIOs for the way airflow is managed. It’s not better or worse than air in many instances, but I like working with a radiator rather than a chonky heatsink.

    I cannot disagree though: zero maintenance is better than maybe-maintenance. Like I said, it’s about tradeoffs. (I can still make my PC sound like a fucking jet engine, though. Noctua server fans kick ass.)






  • Vyvanse wasn’t a pleasant experience for me. It felt like it crushed all of my dopamine receptors and life got really boring, really quick. (Obviously, this isn’t everyone’s experience, but it was mine.) It took a few weeks for my brain to recover.

    I didn’t try switching because I wanted to (adderall works just fine for me), it’s because the adderall supply was low in my area for a bit and I wanted it find an alternative.



  • I agree with the comments on this forum (https://www.thehighroad.org/index.php?threads/mushrooming-22-lr-case-heritage-rough-rider.891807/) that the cylinder could have a machining defect. (Basically a headspace issue, also but kinda not. The cartridges are sitting too deep in the cylinder itself.)

    If there is room for the brass to get pushed back far enough for it to mushroom out, something is seriously wrong. The issue could manifest from a machining error as small as 5-10 thou, I am speculating.

    My first thought was excessive chamber pressure, but the bulging would be much worse around and behind the rim itself if that were the case.

    The bullet and the brass get pushed in opposite directions and if the brass can move, it will move before it deforms. If it deforms, it’ll deform at the weakest spot first, like we see in your pic. (Excessive chamber pressure tends to expand the brass and lock it in place. With center-fire, it’ll blow the primers out or have a hole punched in them from the firing pin first. With rim fire, the pressure pushes back on the rim.)

    Also, check for excessive slop with the cylinder. If it can move forwards and backwards too much, that could also telling of issues with other parts of the gun. (Like I mentioned before, it doesn’t take much for a gun to be out of spec enough to cause issues with brass.)

    Mixed theories on that, and most are older.

    On earlier computers, I had several ICs walk themselves out of sockets due to repeated thermal expansion cycles. Keeping the computer turned on eliminates most of that.

    Mechanical wear was another problem. Booting a computer was extremely taxing on old HDDs and floppy drives.

    Edit: Mechanical stuff also takes much more power to spin up and get running. The energy savings might be measurable if you just kept a computer running and didn’t power cycle it everyday.

    Most power supplies are really well designed now but they had a tendency to spike power briefly in when turned on. This was especially bad for older capacitors but also not healthy for the ICs. This still happens to a degree, but it’s not an issue.

    Now that boot times are reasonably fast and most everything is solid state and power managed really well, turning a computer off is fine.

    However, I just assume most electronics now just go into some type of deep sleep mode unless fully disconnected from any power source. That likely isn’t true in many cases, but I consider it healthy level of paranoia.




  • (The correctly used double negative was confusing for me at first, btw.)

    You make a very interesting point I haven’t ever thought about before.

    While I have always considered myself a patriot to a mild degree, I never associated it with tribalism directly. Even with the many faults of all countries, it’s OK to be proud of where you are from. (It does make perfect sense that tribalism is the end goal of state sponsored patriotism though.)

    In my mind, the fine line after patriotism was usually nationalism where tribalism runs deep and hate-based rhetoric becomes extremely effective. The definition of a patriot is somewhat twisted at that point. (ie: unless you believe [insert something random], you aren’t actually a patriot and therefore an enemy of the state.)

    I am not agreeing or disagreeing with you, btw. Your perspective is something interesting to think about, s’all. (I am leaning on the agreement side, FWIW.)

    (For the people reading this that may not realize that I am using the word “nationalism” in a negative context, I am. If that chaps your hide still, replace it with ‘christian nationalism’ or ‘white nationalism’ and fuck off. Everyone else, sorry for the disclaimer.)

    That combo is too inefficient for me. I like coffee, but if I am prioritizing caffeine and still want something more sugary, an energy drink would be fine.

    So, a bottle of water and a large Red bull would be sufficient and easier to transport, while also staying in-line with what I would carry around if I really wanted multiple experiences.
