    I am guessing the egg-shell foamed enclosure is for the sound, but you probably have a bunch of sound coming from the fan port, nessisary for ventilation. You can cut a lot of the sound but maintain the airflow by cutting an s-shaped ducting spanning the width of the enclosure. The shape will drop the sound, while then ducting keeps the air flowing. I would not recommend any sorts of filters to block the sound because they are a bit too restrictive for an enclosure in your style.


  • The barrels smallest diametral dimension has to smaller than the bullet, otherwise the rifling wouldn’t engage.

    Kind of, but not really. The bullet actually slightly expands from heating. At the same time though, if you measured the diameter of a cold barrel and a hot barrel you would get two different measurements. If the cold barrel is too tight of a fit the bullet has an increased chance of lodging when it heats up and expands.

    This is why bullets moved towards copper jackets with some sort of other metal center chosen for various justifications. The copper jacket is soft, east to expand into rifling grooves, not hard enough to damage and wear out rifling, and can stretch a little if it gets too tight.

    Really, the BIGGEST difference is going to be the casing, chambering, and pressure. It’s like how people talk about 5.56 and .223 being the same. They are the same only at face value of size and chambering, but very different on rated pressures. A rifle rated to shoot .223 should only shoot .223. A rifle rated to shoot 5.56 is rated for a higher pressure and can shoot both.

    In the same regard to OP: 9mm, .357, and .38 special may measure the same, but all 3 chamber very differently and have different pressures.

    Hell, even 9mm has 9mm luger (parabellum) vs 9mm NATO. it’s the same round/casing, but again, different pressure. A gun that shoots luger (lower pressure) should never shoot nato. But a gun that shoots nato (higher pressure) can shoot both.

    It’s also kinda funny how the most common rifle rounds are smaller calibre than 9mm, so if you ignore all the other metrics, most handguns shoot “bigger” bullets than most rifles.

    True, but this is also why “stopping power” is then measured in ft-lb (foot-pounds) or joules for metric. Pistols may shoot bigger rounds, but at significantly slower speeds. Less powder for recoil control and less barrel length for pressure build up. The bigger size bullet is a compensation for the smaller gun. A rile with a smaller round has far more energy behind it’s round.






  • Yeah, like I said, I will never buy a chevy car again. The transmission carrier bearing is worn out. It is also where the speed sensor is housed. So the speedo drops out any time you are not accelerating. This causes a speed/air/fuel mismatch and kills the car any time you slow down unless you keep it in gear (manual). So if I beak too much on the high way or going up to a red light, the car dies and I quickly have to get it in gear and pop the clutch to jump start it, or awkwardly start turning the key to start it normally while moving.

    The bearing is about 35$. Taking out, disassembling, rebuilding, and reassembling, reinstalling the transmission is over 3500$. The car is worth 4k at best. Not worth it. Apparently this is a known issue with this transmission and replacing the bearing just gets you another 100k till you have to do it again.




  • While I fully agree with your comments on aspartame and have read these posted articles, I would have to disagree with you on the regular sugar part. The more we are researching sugar and its connection with heart health, the lower the recommended daily intake becomes. One of the reasons it is in fact still so HIGH of a recommendation is due to the sugary drink lobby going against the American heart association (as well as almost every physician organization) for the FDA recommendations.

    But yes, in moderation you are fine. Just not as freely with the moderation as they make you think you have. This redbull is claiming 26g of sugar is only 53% of you limit, when the AHA limit is only 36g for men (and 25g for women!). So, bad in moderation.

    There is actually a really cool history of color grading and the advancement of computers in film technology. The movie O Brother Where Art Thou was the first movie to use full color correction, that was only possible with newer computer assisted editing, and lead to a Oscar award as well as future technical awards for its impact on film editing. Before that movie, color grading was seen as a last ditch effort to compensate for failings of a lighting director or poor cinematographer and was expensively and painstakingly done on select frames individually, and never done on more than a scene or two. After computers were used for digital editing and made it cheap, fast, and easy (relatively), it has become the standard. And now with digital cameras, it is literally baked into the process. It’s a really fun rabbit hole to go down, would recommend.

    I would agree but with the caveat- everything jj Abrams has touched that he didn’t make originally

    His original works are fine. Super 8 is up there with some of the better modern scifi movies, his work on lost is legendary. But then you have both star trek and star wars… what a failure to both.

    As your tab is auto charged to your biometrics and the bartender points to the door you decide to get the last words in-

    “If something is verifiable sentient then I might change my tune, until then robots can fuck off!”

    Another patron gasps at your lashing out, “did he just use the R-word? I’m so sorry bartender that you have to hear that. Just remember -not all humans.”

    The bouncer approaches you and starts to corral you to the door. “Sir, it’s time for you to go”

    You finish off your final rant from the doorway, “Robotic life will still be a rape baby foisted onto us by corporate technocrats!”

    The door is closed on you. Inside, the bartender’s emotion chip glows, nearing short circuit. The other patron consoles them and tells them, “if you need to take a minute and collect your emotions, I understand. It is a long and hard road to equality.”

    I immediately imagine a scenario 100 years in the future with you in a bar, slightly drunk and provoked by the young’ns to get the old man to rant against the Silicos.

    One of the patrons overhears your offensively biocentric rant and asks you to check you DNA privilege and to stop using life exclusive language and to consider the feeling of silico-life forms and their struggles for equality.

    You then mock them with a silver-face impression “SoRrY, cOuLd NoT cOmPuTe” while doing robot arms.

    The bar tender, who is a synthetic, is on the verge of tears and asks you to leave…



  • Fuuuuuuck yes. It’s up there with all the other ones every one is saying “one of the best ever” the only difference is that no one ever talks about this one. The first 3 or so episodes are a little hard because they were made at peak GoT times and needed to ‘out Got the GoT’ and put in extra sex, violence, and bullshit that was superfluous to the story. But after that, it was pure gold. It needed one more season to finish the story. Two if they wanted to finish ot without rushing.
