    GLOBAL THERMONUCLEAR WAR

    [–] What's the pettiest reason you won't date someone over? jnicho15 2 points ago in AskReddit

    Do they do interviews for normal marriages between two citizens? Or just if one is a foreigner?

    [–] False, I don’t want to be in any of these places at 8am jnicho15 1 points ago in BlackPeopleTwitter

    At my school, Convolutions aren't taught until Differential Equations (Calc 4).

    [–] it works (praise Jesus) jnicho15 1 points ago in FRC

    I'd use some sort of igus rail

    [–] How this star is cut jnicho15 4 points ago in oddlysatisfying

    V-carve cutters are more confusing since they don't have a constant diameter and go up and down, so it's pretty difficult to set up multiple passes well (depending on your CAM software)

    [–] What's something that seems obvious within your profession, but the general public seems to misunderstand? jnicho15 3 points ago in AskReddit

    It's cheaper to do switching in the audio band, but there are ways to prevent the sound itself (which are kind of a pain). I had a graphics card that whined under heavy load (among other issues) and was replaced under warranty with one that is silent.

    Switch mode power supplies (like phone chargers or basically anything electronic besides fancy stereo amps) regulate the wall power to useful voltages by switching on and off very quickly. Some components in the circuit emit small amounts of sound when they charge/discharge. Some nice power supplies operate at a higher frequency than the audible range but that becomes inefficient, so many are in the teens of kHz, audible to younger people but not older. For example, my laptop charger is silent when nothing is plugged in or when the laptop is charging, but it gets loud when the laptop is plugged in but fully charged, drawing a tiny bit of power. The sound is usually visible as a sharp peak on an audio spectrum analyzer. There are a ton of apps (at least for Android) that use your phone's microphone so you can just hold your phone near the charger and see the sound even if it's hard to hear (or other people don't believe you).

    Edit: Wall power itself is a very low frequency (50-60Hz, or the first harmonic at 100-120Hz). It's the hum you hear if you turn a sound system to a very high volume with no input signal.

    [–] Its so cold here in Iowa that there is now Frost on the inside of my door hinges jnicho15 1 points ago in mildlyinteresting

    Same for all of lower Michigan. Consumers energy had a fire at one of their pumping stations so they're running every short term storage facility at 100% to keep up. The state has issued a "severe threat" to all phones saying to turn your heat down to 65.

    [–] That's true you know jnicho15 7 points ago in ProgrammerHumor

    Or if you're writing in RISC assembly, it takes like 20 lines to do anything.

    [–] Seriously though... jnicho15 2 points ago in dankchristianmemes

    The worst is the "I sing praises to your name" song. It's so passive and pointless.

    Those are the only good mechanical pencils every made. The one problem with them is that there is not any stress relief at the bottom of the notch in the body where the eraser/clip snaps in. Most of mine have cracked there, so I have to super glue the eraser in and then muzzleload the lead. Which isn't that bad since that is the superior loading method.

    Or you might get many thousands of dollars per year in scholarships

    I've found the best strategy is to write painfully verbose, then trim it down to be just barely long enough. Like I'll write a terrible paper that's like 1000 words too long and super redundant, then cut out a ton of stuff until it is just barely long enough and get an A.

    [–] What movie sound effects are wildly inaccurate, and what does it actually sound like? jnicho15 326 points ago in AskReddit

    It depends on the type of lights. Some lights might strike an arc which makes a sound, or others might have relays/contactors which make a sound.

    [–] So are U of M Dearborn students actually wolverines? jnicho15 7 points ago in dearbornwolverines

    And, most importantly, we can buy student football tickets

    [–] So are U of M Dearborn students actually wolverines? jnicho15 5 points ago in dearbornwolverines

    They used to be the Wolves until Dave Brandon decided a few years ago that we have no pride.

    [–] RIP Chief Delphi jnicho15 4 points ago in FRC

    Maybe Brandon's vBulliten license renews on January 1st?

    [–] Hot take: Teams should be forced to publicly disclose how much money went into their FRC budget jnicho15 1 points ago in FRC

    Or what would probably happen is that a team would split into 5 technically sperate teams that "work in a shared build space" and basically build the same robot, but the students are technically split into 5 teams.
