hazardous_area, in What are your favorite leftist podcasts?

Go visit maximum fun, the whole network is usually centre left or leftist. Whole range of topics and types with that perspective.

99 PI comes to mind as well Or wait wait don’t tell me’s podcast

Tathas, in What's a good way to prank your coworker?

An old boss of mine would find people who left their computer logged in and would send an email to the department from it saying “I love you all so much!”

I worked in a different office and didn’t realize that’s what was happening. I just thought the Russian guy was happy to be in America.

abbadon420,

I like this. It’s wholesome

Tathas,

One day when I was visiting home office I ran into him in the elevator. My lead introduced me to him. I blurted out, “Oh the guy who sends the I love everyone!” emails.

He promptly started swearing and cursing our manager and saying what things he would do to him if he caught him in a dark alley and ranted for the duration of the elevator ride. Then shook my hand and said “Nice to meet you!” and went on with his day.

ophelia, in How often do you brush your teeth?
@ophelia@lemmy.ca avatar

I brush at least twice a day for 2min 30sec each time. I have an oral b io toothbrush that times it for me, and helps me know when I’m brushing too hard or too soft. I also brush for about 30sec before and after naps, or if I’m about to go out somewhere.

My husband makes fun of me for it, but my teeth are super important to me!

KuroJ, in Does anyone actually enjoy working out?

Depends on the exercise. My favorites are heavy squat and deadlifts. It’s just a good feeling increasing the weight every week and hitting new maxes while getting stronger.

I suck at bench so I’m never looking forward to that, but I’ve set goals to hit by the end of the year so I’m sticking to it.

Honestly now, I feel terrible when I don’t workout and it really affects my mental state.

spclagntdanazoe, in What is a beautiful concept or idea that continues to blow your mind?

Frequency hopping. It’s like hiding messages in music. Always loved that idea.

Cl1nk,

Can you explain this concept like I’m 5?i searched on YouTube but the videos look extremely technical

treadful,
@treadful@lemmy.zip avatar

Frequency hopping as I understand it, is just multiple transceivers agreeing to cycle through different previously agreed upon frequencies to communicate. I don’t get the music analogy.

spclagntdanazoe,

So if you consider that different notes of music are different frequencies of sound, each radio frequency “hopped to” would be a different note on a piano being played on either end of the signal.

From Wikipedia: “Antheil and Lamarr developed the idea of using frequency hopping: in this case using a player piano roll to randomly change the signal sent between the control center and torpedo at short bursts within a range of 88 frequencies on the spectrum (88 black and white keys are on a piano keyboard). The specific code for the sequence of frequencies would be held identically by the controlling ship and in the torpedo. This basically encrypted the signal, as it was impossible for the enemy to scan and jam all 88 frequencies because this would have required too much power. Antheil would control the frequency-hopping sequence using a player-piano mechanism, which he had earlier used to score his Ballet Mécanique.”

nekat_emanresu,

aaaand there is the missing part of my understanding about jamming and frequency hopping radios! Thanks

LongRedCoat, in What's it like working night shift?

Look up "night shift belly." I did night audit at a hotel for a year and a half. By the end, I could only really stomach eating the kale salad from Whole Foods and not much else.

It also wrecked my social life and when I got sick, I got really sick, so I think my immune system was out of whack in general.

Like others have said, the commute is a dream. The shift itself is quiet with plenty of time to have deep conversations with any coworkers you may have, read, listen to podcasts, etc. It's like living in a different world.

I say give it a try, but listen to your body and find something else soon if your health is affected.

SFDope, in Does anyone actually enjoy working out?

I’m at a point where sometimes I don’t want to go lift, but it’s part of my routine that if I don’t go I feel like shit. a chore to go, change and warm up but 20min in I just fall in the zone

Rick512, in What is a beautiful concept or idea that continues to blow your mind?

The scale of the universe. It’s an incomprehensible amount of emptiness.

OsrsNeedsF2P,

Highly recommend the browser game Orbity.io

Cl1nk,

I just played it, such a fun game. Not exactly what I thought it was going to be when it come to the infinity of space

yunggwailo,
@yunggwailo@kbin.social avatar

It honestly pisses me off lol. I was so into space as a youngin but as Ive gotten a better grasp of the scale and what is actually possible in physics Ive realized its a massive boondoggle. Real pretty though

abbadon420,

I still refuse to believe that we can’t overcome the limit of the speed of light. Maybe it’s something like “warpspeed”, maybe it’s something like evolving beyond the need for a physical body, but I believe that at some (far) point in our future we will solve that problem.

yunggwailo,
@yunggwailo@kbin.social avatar

Speed of light is a bit of a misnomer, its really the speed of causality; the least amount of time it can take for one thing to interact with another. It will never be possible to overcome that limit unfortunately

Telodzrum,

Nah, it’s impossible with our current understanding of the nature of the universe and it’s rules. Every time that has been true of something, humanity has eventually either solved the problem or rendered it moot. This one may just take a while.

yunggwailo,
@yunggwailo@kbin.social avatar

Respectfully disagree. The math speaks for itself

Telodzrum,

How shortsighted.

AmbientChaos,

You should look into the effects on causality of going faster than the speed of light. If you can send information faster than the speed of light all kinds of wacky paradoxes show their heads. I used to believe what you did, that with time and knowledge we could overcome the speed of light. But after learning more about our universe I don’t think that’s the case anymore. I enjoyed this video on the topic youtu.be/an0M-wcHw5A

yunggwailo,
@yunggwailo@kbin.social avatar

Its shortsighted to trust math?

tatterdemalion,
@tatterdemalion@programming.dev avatar

A fact I’ve recently enjoyed spreading around: all of humanity’s radio communications have traveled about 200 light years from Earth. The diameter of the Milky Way galaxy is ~100K light years. So (in the worst case) we’re like 0.2% of the way to even being a “blip on the radar” of any alien life within our galaxy.

TitanLaGrange,

all of humanity’s radio communications have traveled about 200 light years from Earth

Also interesting is that because the energy of those signals is spreading out as they move away from their point of origin they become less detectable as they travel. Most signals would fall below practical detection limits before making it halfway to the nearest star. At the extreme, the Arecibo Message, transmitted with a ridiculous ERP, will be detectable to reasonably sized receivers for tens of thousands of light years, assuming they are located along the path of the beam.

Ab_intra, in Does anyone else struggle with silence, particularly when trying to sleep?
@Ab_intra@lemmy.world avatar

I would love absolute silence. I got Tinnitus in my right ear 24/7/365… It will probably never disappear… And I also sleep with a CPAP which makes annoying sounds when sleeping. So I would absolute silence.

lvxferre, in What is a beautiful concept or idea that continues to blow your mind?
@lvxferre@lemmy.ml avatar

Evolution as a concept; not just biological. The fact that you can explain the rise of complex systems with just three things - inheritance, mutation, selection. It’s so simple, yet so powerful.

Perhaps not surprisingly it’s directly tied to what OP is talking about cellular automata.

dipbeneaththelasers,

There's something interesting in here about the persistence of legacy systems that I can't quite put my finger on. Rest assured I will be consumed by the thought for the remainder of the day.

lvxferre,
@lvxferre@lemmy.ml avatar

There are plenty things that we could talk about legacy systems from an evolutionary approach. It’s specially fun when you notice similarities between software and other (yup!) evolutionary systems.

For example. In Biology you’ll often see messy biological genetic pools, full of clearly sub-optimal alleles for a given environment, decreasing in frequency over time but never fully disappearing. They’re a lot like machines running Windows XP in 2023, it’s just that the selective pressure towards more modern Windows versions was never harsh enough to get rid of them completely.

Or leftovers in languages that work, but they don’t make synchronic sense when you look at other features of the language. Stuff like gender/case in English pronouns, Portuguese proclisis (SOV leftover from Latin in a SVO language), or Italian irregular plurals (leftovers of Latin defunct neuter gender). It’s like modern sites that still need animated .GIF support, even if .WEBM would be more consistent with the modern internet.

treadful,
@treadful@lemmy.zip avatar

DNA still blows my mind. Some weird simple molecules that just happen to like to link together have become the encoding of how complex biological systems are constructed. Then mash two separate sets of DNA together, add a little happenstance, and you have another new being from those three things you mentioned.

lvxferre, in What replacement for each major social media do you use
@lvxferre@lemmy.ml avatar

Lemmy is a given, since I’m fairly active here.

I’ve been using Mastodon even if I was never a Twitter user. (Or at least, not a serious user. I had an account some time ago, as I was dating a girl who posted there often and she insisted that I should use it.)

I’ve been trying to convince people to migrate from Whatsapp to Signal. Easier said than done due to network effect.

Moonguide, in Does anyone actually enjoy working out?

I enjoy the simplicity of weightlifting. Make sure your form is good, count reps, count sets, take note of the weight lifted. All of that keeps my mind occupied for 2h, no room for it to wander into topics I’d rather not think about atm.

I also find some measure of joy out of knowing I’m lifting more today than I was last week, it’s simple and measurable progress. No room for subjective bias, unlike other things I’m trying to improve upon.

It also has the added benefit of tiring me out. GAD and ADHD make for horrible bedfellows, they’ve made nights sleepless for me more often than not, so I’ll take any help I can get.

Edit: otoh, I hate cardio with a passion. Its boring and does nothing but make me sweat and lets my mind wander. I’ve tried everything, from music, to audiobooks, to podcasts. Plus, I feel like I run loudly, like my feet are made of lead, and I don’t like being loud.

Locuralacura,

Have you ever tried swimming? No sweat, no loudness, great cardio.

Moonguide,

Used to swim when I was a kid, was pretty good too apparently. Coach wanted to put me in a pre-15 y/o (10-15 y/o) competition when I was 6 or 7. Got cold feet and dipped out. I dunno if I could take it as an alternative though, I’ve done it now and again but it feels like running. I prefer HIT and even that I don’t love.

Locuralacura,

I love swimming because of the rhythm, the breathing, the form and it feels like flying. It’s also very quiet. Like the noise of the world goes away first. And eventually, when I find my rhythm, my brain stops it’s busyness. People tell me this about running, but running just hurts my knees a bit.

Ab_intra, in Hey Lemmy, what are your favorite ear worms?
@Ab_intra@lemmy.world avatar

I hate that… Mostly because I can go around for days having a song in my head and can’t for the life of me stop getting it off.

cokane_88, in What password manager do you recommend?

Online password manager GTFO never ever doing that.

I use password safe desinged by Bruce Schneier, it’s legit AF, pwsafe.org

mojo,

Do you not need to sign in to your accounts from different devices? Not to mention autofill support is a big deal, hence why browser addons are so important. The other password managers are plenty secure, especially with 2fa and webauth which that app certainly is not going to have.

cokane_88,

The convenience factor is not there but you probably sacrifice security for the conveniences. Browser add-on is something else that can get hacked.

mojo,

What do you do for a living where you somehow don’t need mobile autofill? Do you not leave the house?

cokane_88,

I used do cyber security for a fortune 500, that’s where I got exposed to that password manager. Now I don’t work, stay at home dad aka house manager.

magicalbeast69,

Why are online password manager bad? Sure, the risk is obviously higher than the offline one, but online password manager would be sufficient for most people. Convenient outweigh for like 99.99% of people. Even if there is a data breach, passwords’ hashes are not easy to crack, even if you know the salt. The only way to crack it is that you reuse password. So, as long as you use strong enough master password, it’ll most likely be fine.

Also, if you care about security, you’ll also probably be using TOTP 2FA anyway. So unless, TOTP secret is leaked at the same time as your password, then you are fine.

cokane_88,

blog.lastpass.com/…/security-incident-update-reco…

That’s a breach they told the public about. What’s worse is when a company gets breached and they don’t know it happened or it takes them years to find out. I’d rather step on my own ding ding than put my credentials online.

DanTheMan827, in What replacement for each major social media do you use

Unless the communities you visit move, it’d be very difficult to move entirely.

This applies to discord especially.

They’re more of a compliment to the other social networks in many cases

OsrsNeedsF2P,

Yup. Reddit is 100% gone but Discord remains used for me

jackpot,
@jackpot@lemmy.ml avatar

convincw friends by saying no nitro there

Grimlo9ic,
@Grimlo9ic@kbin.social avatar

Same. I've stopped with Reddit since I've never posted there with my real name. No one knew me personally, and I didnt know anyone personally, so my switch to kbin was easy.

My real-life family and friends use Discord, Instagram, Messenger, Twitter, Viber, and WhatsApp, so I'll continue to at least have accounts on those.
