CaspianXI, in How fluent do you think one have to be to be considered "bilingual"?
@CaspianXI@lemmy.world avatar

“Bilingual” is really hard to define.

I live in Taiwan (English is my native language), and have studied Chinese to be passably fluent. I can trick people into thinking I can follow advanced conversations, interjecting comments here or there (even though I’m mostly lost – just picking out the tidbits I do understand and commenting on them).

But am I bilingual? At the end of the day, it doesn’t really matter. What matters the most is whether your level is “good enough” to do what you want! In my case, I just want to be able to go to the store, buy things, and hang out with friends. I can read the newspaper, but I’ll never be able to read/write business contracts – but that’s not a goal of mine.

There are so many different shades of bilingual. Don’t worry about it… and just be as good as you need to reach your goals!

agoramachina, in What series did you rewatch most often?

Love, Death, Robots; Black Mirror; and The Good Place.

Each of those is comfort media for me in their own way.

Edit: Oh! And Star Trek, particularly TNG

@BrainisfineIthink@lemmy.one avatar

Yeah, I use it to wipe on my nose when I’m sick or my allergies are bad. It helps prevent it from getting all dried out from the tissues! I also rib a little on my hands sometime#, it goes a long way as a moisturizer. In summer I rub some between my toes if they get dried out.

You’ll have a local copy of any communities you follow, even if their origin is offline

Upsides:

  • You can federate with whoever you want and not be at the whim of other system admins.
  • You have your data and won’t lose it if your instance suddenly shuts down.

Downsides:

  • Your instance won’t be federated very well at first. You may need to use some tricks like Lemmony to get broad federated content to show up in your instance.

Another possible downside is a lack of an administrative toolchain. Hopefully one should be forthcoming soon. My database may end up growing huge.

PriorProject,

Folks should not use lemmony to bootstrap their subscription count. It’s not that hard to hit lemmyverse.net and just manually sub a bunch of stuff you’re actually interested in, or to visit a big instance and browse their all feed unauthenticated.

But if you really want to automate community bootstrapping, lemmony is the worst of the scripts that doit because it defaults to subscribing to EVERYTHING, including all the porn, piracy, and hate communities on the most absent-admin’ed under-modded instances in the lemmyverse. Then your instance will mirror all those questionably legal communities and re-serve them to the public unauthenticated internet, creating hosting liability for you. Not to mention being a bad fediverse citizen and creating massive amounts of federation load on the instances forwarding you posts and comments from 20k communities that you don’t read.

These two subscription bootstrapping scripts limit you to top subs by default… So you’re more likely to be in well-modded territory and just the number of subs is smaller you you can review them and back out of anything sketchy. Subscriber-bot’s docs do a good job of explaining the risks and problems of mass-subscription so you know what you’re getting into.

mcmxci,

Commenting to vouch for lcs. It works well and isn’t resource heavy

Additionally it’s going to cause you headaches if your server is low spec. The federation queue is not well optimized for GIGANTIC subscription counts like this. There is an active draft PR working on it, but using that script is still a bad idea.

clutchmatic,

Then your instance will mirror all those questionably legal communities and re-serve them to the public unauthenticated internet, creating hosting liability for you.

To be frank, this liability risk exists even in well-moderated communities as it only takes one rogue poster/commenter to “contaminate” your own instance…

PriorProject,

Liability is not binary. There is a qualitative change in risk as you transition from “I subscribed to 100 actively moderated communities that I read and am familiar with” toward “I subscribed to everything there is including the worst of the worst and I didn’t realize I was doing so and don’t look at the results”.

Also, moderation activities federate. So even if a rogue poster does “contaminate” the actively moderated communities on a well-admin’ed instance… when those mods and admins delete the offending material they’ll automatically cleanup your instance as well. As a result, it’s the creepy crawly communities that don’t clean up or don’t want to clean up that generate the lion’s share of risk.

Is it 100% safe to sub to well-moderated communities, no. You have to know your local laws and protect yourself. Do you do yourself favors by running lemmony? Also no. These two statements can be simultaneously true.

Blaze,

Thank you for this!

Harlow is in the fireplace, Adobo is in the window, and Sesqua is on the couch.

For some reason, I used the memory palace to remember that several years ago when I first heard about it and I still remember it.

abbadon420,

ohlaph,

Pure randomness. Just wanted to try and memorize random things to see if it works.

Do it! I struggled to get mine going. But in doing so, I got a lot better using docker.

jetsetdorito,

One day I’ll learn how to use Docker

TheSaneWriter,
@TheSaneWriter@lemmy.thesanewriter.com avatar

Docker’s honestly really easy to use, is there anything specifically challenging you about it? I’d be happy to explain how any of it works or how to use its features.

housepanther,
@housepanther@lemmy.goblackcat.com avatar

It’s only easy if you know how. If you’re just learning it can be challenging because documentation is spartan and makes assumptions.

I use it to prevent chafing when swimming.

I use it on the threads of plastic filter housings in my engine room. It’s keeps the salt water from seizing them.

If you also use a password manager, then 1Password is what I use since it handles both and does cross platform and can auto fill on mobile.

Any solution that holds both together… is not really a 2fa solution imo.

rusticus1773,

True but still better than no 2FA. Would be great if these password managers informed a second level of security (ie different password) into their 2FA.

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.

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

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
