snek_boi, in What are some useful or just cool stuff to memorize?

The mneumonic major system. Once I learned it by heart, it helped me memorize all kinds of numbers: cards, IDs, passwords, addresses…

Anticorp,

That sounds a lot more complicated than just memorizing the number itself. How long did it take before you felt comfortable with this?

snek_boi,

To give an extreme example:

“I solemnly swear that I am up to no good.” vs. “053250411391271”

But to be fair, I never end up with nice sentences. It’s more like “Thank you, rainbow. Clock firework” and I imagine myself thanking a rainbow and telling it to “clock firework”, whatever that means…

As to how long, I think it could’ve been a couple of months doing a dozen or so conversions. In total it’s a very small investment of time, assuming you space it out and don’t cram. It really helps to use the Wikipedia mnemonics (like how 4 is kinda like a mirrored R).

Anticorp,

Thank you. I’ll give it a shot, since the example you gave is awesome.

This is the one I'm waiting for. @ArtemisApp

BionicHippo,

I’m using the iOS beta right now and really enjoying it. It’s working through kinks but very promising. I believe the dec said Artemis will support Lemmy in the future too. It would be awesome to have multiple platforms in one app.

I've been using the beta on Android for about a week. It gets updates constantly, sometimes multiple times a day. Keeps getting better and better.

Igloojoe,

I believe the dude who made sync is working on a kbin app.

Dreamer_joy,

Thanks for the information.

Pepperette, in What do you use Vaseline for?

When I get a cut on my hands and they are very dry my skin heals over the wound, but the wound still stays there. Callouses just kind of grow over it and it gets painful and shitty. I put a glob of Vaseline on it and cover it with a bandaid or something and I a few days it’s back to normal.

DM_ME_SQUIRRELS,

Now I wonder if it would work on those tiny painful as fuck cuts that you get around your fingernails during winter when your skin is dry. I’ve been using those expensive Compeed bandaids which do provide instant relief but if it’s just about blocking the air then maybe Vaseline could be just as good.

Pepperette,

Absolutely it does. I work with chalk and know exactly what you’re talking about. The super treatment is to lube up and wear cotton gloves. Really works quick.

That’s a lot of the reason why Neosporin or any other antibiotic ointments help you heal faster. There’s petrolatum in all those products.

AceFuzzLord, (edited ) in What gaming console / platform do you prefer?

If we are talking strictly console, then the xbox360 is my all time favorite console and preferred console, especially since my absolute favorite controller goes to them as well.

Otherwise, PC is just more convenient for the fact I can use a 3rd party 360 controller and play console games via dedicated emulators or RetroArch cores.

I have a few other consoles, but my desktop and 360 are most definitely my picks for what I’d use if given the choice.

If I had a hacked switch and my computer had better specs to run pokemon violet at even close to 30 frames per second, you bet I’d just back up my games onto my desktop and play them on it using my 3rd party 360 controller.

80085, in Why is youtube recommending conservative "talking points" to me?

If I use a private window, and don’t log in I get a lot of right-wing stuff. I’ve noticed it probably depends on IP/location as well. If at work, youtube seems recommend me things other people at the office listen to.

If I’m logged in, I only get occasional right-wing recommendations interspersed with the left-wing stuff I typically like. About 1/20 videos are right-wing.

YouTube Shorts is different. It’s almost all thirst-traps and right-wing, hustle culture stuff for me.

It could also be because a lot of the people who watch the same videos you do tend to also watch right-wing stuff.

In general, the algorithm tries to boost the stuff that maximizes “engagement,” which is usually outrage-type stuff.

PriorProject, (edited ) in Advantages to selfhosting a Lemmy instance?

The upsides are that you control your defederation list and you’re your own admin so you’re in control of whether your instance goes down and what it’s policies are.

The downsides are:

  • Potential privacy leaks. Your all feed is public. If its full of creepy shit and you’re the only person in your instance, it’s there cause you subscribe to creepy shit.
  • You’re in control of whether your instance stays up. Security vulnerability gets mass exploited? Your problem.
  • Potential hosting liability. Your instance mirrors what you sub and serves it to the public unauthenticated internet. If you subscribe of stuff that’s questionably legal in your jurisdiction, that liability can become yours unless you’re familiar enough with your laws to know how to protect yourself.
  • All the standard self-hosting stuff like cost and hassle.
ScreaminOctopus, (edited )

An option to remove unauthenticated access to the main feed would be a great fix for the first issue, and probably would be desirable on single user/invite only instances where the admins don’t want random people taking up server resources with the web interface

PriorProject,

This isn’t a terrible idea, but it’s also important to understand single-user and tiny invite-only instances as analogous to “leechers” in the torrenting world. The federation load that an instance instance imposed on other instances depends much more on the number of communities it subscribes to than the number of active users. If a user stops using Lemmy but leaves their instance up, it’s generating federation load for no reason.

Tiny instances are inefficient, and while it is desirable for the network to be able to scale to the point where it can reasonably support lots of them anyway, right now federation queues are backed up and messages are frequently getting dropped. Encouraging lots MORE tiny instances is probably not the efficient thing right this second. Rather, we’d want more users joining mid-sized instances that are not overloaded locally and that are making efficient use of the federation load they generate by using it to serve 100-1000 users rather than 1 or 2.

“Nice to see you’ve hosted your instance. Quick question: Why is your instance filled with hentai that that features underaged characters?”

red,

Potential privacy leaks. Your all feed is public. If its full of creepy shit and you’re the only person in your instance, it’s there cause you subscribe to creepy shit.

That’s why you always invite a few victims friends, so you can throw someone under the bus if need be.

stealth_cookies, in What series did you rewatch most often?

I don’t rewatch series very often, but every couple years I watch the British comedy Coupling again.

Sharkapotamus,

The Giggle Loop is still one of the truest elements of human life ever explained by a sitcom.

Tyfud,

The sock gap.

guleblanc, in What do you use Vaseline for?

Lubricating the cork in a saxophone neck or a clarinet tenon. It turned out to be not a good idea at all, since the Vaseline speaks into the cork and dissolves the glue holding the cork to the instrument. But until then it does a great job.

tiredofsametab,

speaks into the cork

Soon, Cork could no longer ignore those dark whispers, those awful voices. Cork knew what needed to be done, and that only they could do it.

VerdantSporeSeasoning,

Cork let go. Cork was… Free.

And then came an explosion of sound.

arthur, in What are some useful or just cool stuff to memorize?

Do you remember the Fibonacci sequence? You can use it to convert miles to kilometers .

2 mi ~= 3km

5mi ~= 8km

8mi ~= 13km

13mi ~= 21km

And so on.

soggywhale,

That’s awesome thanks !

DoctorWhookah,

Wait, is this true until its not or is it true forever as you go higher in the sequence?

masochismworld,

Conversion factor of miles to kilometers is about 1.609 and golden ratio is about 1.618, it will be pretty accurate for quite a while…

liam_galt,
@liam_galt@lemmy.blahaj.zone avatar

It’s true forever. The Fibonacci sequence used in this way converges on the golden ratio, which is close to the conversion of km and mi.

Anticorp,

So are you telling me that the inventors of the mile were using the golden ratio?

Maya,

We wish they were that cool, the inventors of the modern mile were more concerned about land measurements. A square mile is 640 acres. Which neatly can be cut into quarters 3 times. 160, 40, 10.

arthur,

Just a neat coincidence

kakes,

Someone already replied with a graph, but I also got curious and checked for some higher numbers. Sure enough, it held up.

For example:
832,040mi => 1,346,269km (actual: 1,339,039km)

snek_boi, (edited )

I think the way to formally prove this is to find the difference between the Fibonacci approximation and the usual conversion, and then to find whether that series is convergent or not. Someone who has taken the appropriate pre-calculus or calculus course could actually carry it out :P

However, I got curious about graphing it for distances “small enough” like from Earth to the sun (150 million km). Turns out, there’s always an error, but the error doesn’t seem to be growing. In other words, except for the first few terms, the Fibonacci approximation works!

This graph grabs each “Fibonacci mile” and converts it to kilometers either with the usual conversion or the Fibonacci-approximation conversion. I also plotted a straight line to see if the points deviated.

https://lemmy.ml/pictrs/image/528b1166-8b5d-481d-a7bc-180947c29520.png

Edit: Here’s another graph

https://lemmy.ml/pictrs/image/003c6f1a-5555-45d3-a4d6-e4b5ddae71ec.png

So it turns out:

  • Fibonacci-approximated kilometers are always higher than the usual-conversion kilometers
  • At most, the difference between both is 25%. That happens early on in the terms.
  • After that, the percentage difference oscillates around a value and comes closer to it.
  • When talking about more than 100 miles, the percentage change approximates 0.54.

TL;DR:

  • Yes, the Fibonacci trick is true forever as you go higher in the sequence if you’re willing to accept a 0.54% error.

You just did the math!

snek_boi, (edited )

If someone wants to play around with the code, here it is.

Note that you need RStudio and the Tidyverse package.

klemptor,

Mmm dat ggplot2 but ggthemr::ggthemr(“flat”) is where it’s at.

snek_boi,

Checked it out and love that package! Thanks for the recommendation :)

kogasa,
@kogasa@programming.dev avatar

The ratio of consecutive terms of the Fibonacci sequence is approximately the golden ratio phi = ~1.618. This approximation gets more accurate as the sequence advances. One mile is ~1.609km. So technically for large enough numbers of miles, you will be off by about half a percent.

abejfehr,

It’s always true because the ratio of miles to km is really close to the golden ratio.

If you do it for a zillion miles you’ll be off by a lot of km, but proportionally the same amount as for 1 mile

mp3, in The Best Two-Factor Authentication App? (iOS)
@mp3@lemmy.ca avatar

There’s 2FAS. It’s open source, available on Android and iOS as well as on desktop through the browser extension.

rustydomino, in The Best Two-Factor Authentication App? (iOS)
@rustydomino@lemmy.world avatar

Surprisingly, Microsoft Authenticator works very well. On iOS it lets you back up your authentication tokens to iCloud and on Android I believe there is some way to do this too (I don’t have an Android phone so idk). I would avoid Google Authenticator because to the best of my knowledge there is no way to back up, and at some point in the past it crashed on me and I lost all my 2FA logins, which was a huge pain to recover from.

TORFdot0,

Authenticator allows you to back up your passcodes to to your google account. I actually prefer DUO’s way of backing up 2FA codes by protecting them with a different password. I don’t like google’s approach as it basically means that if your google account is compromised then the attackers have the keys to the castle.
