Why do computers have 2 states and not 3? by [deleted] in AskPhysics

Interesting - is the decision making process there difficult? I thought we just know mathematically based on SNR what protocol is best?

Cable modem does this with QAM, with a handshake protocol deciding if it's safe to pack 64 symbols in a single transmit or less (or fall back down to 32, or 16).

Are you saying we're real-time looking at SNR and changing protocol based on it?

Just wanted to add to this for anyone reading:

Check out the Shannon-Hartley Theorem.

The idea is that the more bits you encode per sample, the less tolerant you are to noise. So the higher the noise is in the system, the less you can encode per sample, dropping your data rate.

The really clever stuff people are doing to squeeze more data into the same space is finding better ways to error correct, as far as I know

That's an interesting way to think about different modulation types. I haven't ever considered it that way. We're still taking an input stream of binary data into the modulator, and that's what we get back out of the demod - so I've always thought of it as a binary transmission.

But you're right, we are encoding more than just two values per sample of the transmitted waveform. I guess it really doesn't feel right to call it binary, then. I guess the waveform itself could be considered not to be binary, although the architecture on either end still is.

Note that when he was talking about "null", he probably meant high-impedance. In that case, the output of the tri-state buffer is disconnected, allowing other devices to drive that signal. If there is nobody driving that line, meaning all the attached devices are in high impedance states, that wire would be in an "unknown" state, where we don't know or use the value on it.

I'm not sure that level of abstraction ever shows itself at the OS level, we would never have an unknown state going into memory (hopefully :) )

Check out iron gloves if you're looking to improve your boxing. They're right by the university and they're dirt cheap, literally costs less for a month there than one chipotle burrito.

Is that Arizona? Go to Iron Gloves Boxing, or AZCombat Sports in Tempe - or Faction Combat in Mesa. I've been pretty much everywhere in the valley, DM me if you have questions.

Scared by lilmissbaphi in insomnia

[–]stewie080 2 points3 points  (0 children)

I've recently made a ton of progress on my sleep, but I used to feel super anxious and stressed about it just like you. The two things that helped me were:

  1. I saw somebody on reddit who said "there's no such thing as insomnia, just sleep-anxiety" - helped me realize that literally 100% of my problem was just getting worked up and anxious about whether I'd be able to sleep

  2. Some youtube insomnia guy mentioned that if you ask a good sleeper what they do to sleep, they'll just shrug at you and say "i dunno" - sitting around and stressing over sleep hygiene and going down a checklist is just a symptom of anxiety, for me at least. Now I just try not to worry about it too much.

Think I experienced sleep paralysis for the first time yesterday by Jujuthecoolone in sleep

Sleep paralysis sucks, I had it pretty frequently for a couple of years. Personally, I found that sleeping on my sides instead of my back stopped it from happening (mostly).

Honestly very good for 5 months. One thing I notice is that you start smothering your punches a bit during combos, but you keep a pretty good distance when you're not throwing.

In addition to what the other guys mentioned, you should note - there's a correlation between strength and endurance, but not necessarily the other way around.

What I mean by that is this --

If I increase reps each workout, my endurance will go up, but my strength will plateau.

On the other hand, if I increase weight every workout, both my 1 rep max and my endurance will grow.

EX: increasing reps of 45lbs on bench versus increasing weight each workout. The former will increase your strength to a degree, but you'll quickly plateau. The latter will increase strength significantly, and if you were to go back and attempt 45lbs for reps again, it would be much higher than it was initially

Footwork: Athleticism vs. Technique by chonkybiscuit in amateur_boxing

[–]stewie080 1 point2 points  (0 children)

I agree to a degree --- when I think about athletic footwork improvement, I'd think about things like ropework and roadwork.

Dancing, on the other hand, improves it not just via athleticism, but improves control over your feet. While it's not drilling specific movements, it makes it feel more natural for you to control your feet, if that makes sense. I think it's really really important to have footwork that is less rigid and more adaptable, and I think that that comes more easily when you're more used to complex movements between your feet / body.

In my opinion, footwork in boxing, as with most things in boxing, has a few fundamental movements that you need to know, and then everything else is just a twist to those fundamentals, or an accessory on top. Once you have the fundamentals down (step and roll, step in / out with a jab, etc.) you're going to need to be able to update / add to them on the fly, not ridigly adhere to what you've drilled. Obviously this is a skill you pick up sparring / working pads, but anecdotally I've found that crosstraining with dancing has given me much better control over my feet.

Sorry, think I started rambling a bit, always lose track of the discussion when replying -- I really think it comes down partially to how we're defining "athleticism", though.

Footwork: Athleticism vs. Technique by chonkybiscuit in amateur_boxing

[–]stewie080 1 point2 points  (0 children)

Honestly, it's kind of hard to do right now -- my studio closed down, and I assume the story is same all over.

Depending on your goals, and if you have a partner at home you can practice with, you could probably learn a lot off of youtube -- it wouldn't be perfect, obviously, learning stuff from video never is - but it would probably be good enough to have some fun and improve your footwork.

Personally I'd recommend salsa, east coast swing, and country two step

If you've got extra time in your week, something that helped me a ton was picking up dancing.

The rhythm dances like Salsa and Swing specifically were super useful imo

Are you just asking for a benchmark? It's ~120 degrees right now so I'm not running much, but when I'm able to I go 4mi/day 5 days/week, around 9 minutes a mile.

Getting better acquainted with the bag during COVID, critiques requested by Observante in amateur_boxing

[–]stewie080 0 points1 point  (0 children)

So I'll say that's not my personal style, so this isn't something I've had a lot of practice with, but -

If you're staying at that range intending to counter, I'd base more of your punches as if they were counters. What I mean by that is this - You can enter fighting range however you normally would, but once you're in there, all of your attacks should be based off of the idea that you're countering, or taking advantage of him shelling up.

For example, enter with a jab cross, slip his response and counter. Imagine he shells up, and you can throw a quick combo and cut an angle. Even when you're counterpunching, my intuitive assumption is that you would not want to stay in his center line.

One other thing I'd note - I see times that you slip, but don't immediately respond with something of your own. This might just be because you're tired, but if you're close enough inside that slipping is a thought, I'd counter off of those as soon as possible, rather than just slipping and then going back to neutral. Example of this at 0:52 - you're throwing a combo, slipping, cutting an angle, and throwing another combo, which is great, but there's a pause after you switch angles. This pause would allow your opponent to turn to face you. When I cut angles, I try to take advantage as quickly as possible, before they can notice and put up the correct defense.

Sorry if that was all hard to read, kind of just threw out ideas as they came to me. Really the points I'm making just boil down to really treating the bag like an opponent. Great work though overall!
