Phishing Mails (lemmy.world)

This will be a quick post. We have received a phishing mail to our [email protected] mail address telling that they are “lemmy.world Security Team”, telling that they will “disconnect” your account from our instance. This is ofc, not us. Do not fall for it! The attached image is how the mail looks like....

affiliate,

how do you know it’s not from the secret second mod team?

affiliate,

i click every link that shows up in my email, keeps life interesting

affiliate,

having [email protected] as your personal email would be pretty sick. i would love to put that on my resume

affiliate,

you don’t have to tell your peers that, you can still convince them to switch anyways

affiliate,

this a good explanation.

capitalist apologists love to invent new terms like “corporatism” and “crony capitalism” that basically just mean “every problem with capitalism”. they then say “capitalism isn’t the problem, the problem is crony capitalism” which makes about as much sense as saying “capitalism isn’t the problem, the problem is all of capitalism’s problems”.

they live in a different dimension

i thought they meant 2^0^ + 1, but this makes way more sense

affiliate,

for anyone curious, here’s a “constructive” explanation of why a^0^ = 1. i’ll also include a “constructive” explanation of why rational exponents are defined the way they are.

anyways, the equality a^0^ = 1 is a consequence of the relation

a^m+1^ = a^m^ • a.

to make things a bit simpler, let’s say a=2. then we want to make sense of the formula

2^m+1^ = 2^m^ • 2

this makes a bit more sense when written out in words: it’s saying that if we multiply 2 by itself m+1 times, that’s the same as first multiplying 2 by itself m times, then multiplying that by 2. for example: 2^3^ = 2^2^ • 2, since these are just two different ways of writing 2 • 2 • 2.

setting 2^0^ is then what we have to do for the formula to make sense when m = 0. this is because the formula becomes

2^0+1^ = 2^0^ • 2^1^.

because 2^0+1^ = 2 and 2^1^ = 2, we can divide both sides by 2 and get 1 = 2^0^.

fractional exponents are admittedly more complicated, but here’s a (more handwavey) explanation of them. they’re basically a result of the formula

(a^m^)^n^ = a^m•n^

which is true when m and n are whole numbers. it’s a bit more difficult to give a proper explanation as to why the above formula is true, but maybe an example would be more helpful anyways. if m=2 and n=3, it’s basically saying

(a^2^)^3^ = (a • a)^3^ = (a • a) • (a • a) • (a • a) = a^2•3^.

it’s worth noting that the general case (when m and n are any whole numbers) can be treated in the same way, it’s just that the notation becomes clunkier and less transparent.

anyways, we want to define fractional exponents so that the formula

(a^r^)^s^ = a^r^ • a^s^

is true when r and s are fractional numbers. we can start out by defining the “simple” fractional exponents of the form a^1/n^, where n is a whole number. since n/n = 1, we’re then forced to define a^1/n^ so that

a = a^1/n•n^ = (a^1/n^)^n^.

what does this mean? let’s consider n = 2. then we have to define a^1/2^ so that (a^1/2^)^2^ = a. this means that a^1/2^ is the square root of a. similarly, this means that a^1/n^ is the n-th root of a.

how do we use this to define arbitrary fractional exponents? we again do it with the formula in mind! we can then just define

a^m/n^ = (a^1/n^)^m^.

the expression a^1/n^ makes sense because we’ve already defined it, and the expression (a^1/n^)^m^ makes sense because we’ve already defined what it means to take exponents by whole numbers. in words, this means that a^m/n^ is the n-th square root of a, multiplied by itself m times.

i think this kind of explanation can be helpful because they show why exponents are defined in certain ways: we’re really just defining fractional exponents so that they behave the same way as whole number exponents. this makes it easier to remember the definitions, and it also makes it easier to work with them since you can in practice treat them in the “same way” you treat whole number exponents.

nooo don’t delete california

Californians will be able to delete all personal online data with first-in-US law (www.theguardian.com)

The new bill reinforces that all data brokers must register with the California privacy protection agency, and it requires the CPPA to establish an easy and free way for Californians to request that all data brokers in the state delete their data through a single page, regardless of how they acquired that information. If data...

affiliate,

the full sentence you’re quoting is

The new bill reinforces that all data brokers must register with the California privacy protection agency, and it requires the CPPA to establish an easy and free way for Californians to request that all data brokers in the state delete their data through a single page, regardless of how they acquired that information.

i’m not a lawyer, but it seems to me that it’s saying the new bill would require data brokers to register with the CPPA in order to operate in california (regardless of where the companies are based). then, this registration process would force them to comply with the “delete their data through a single page” process (or pay a fine).

the rest of this article seems to support this interpretation.

it may be of some comfort to know that some geometric things are impossible to draw. this can make them tricky to visualize.

not even all “2-dimensional” things can be drawn. a classic example of this is the klein bottle, (a 2-dimensional manifold) which would need 4 dimensions for a “proper representation” in euclidean space.

that would really help with playing video games

that’s some nice 6-dimensional thinking! very well suited to the new blockchain project

Twitter is losing daily active users. CEO Linda Yaccarino confirmed it. (mashable.com)

By now, you may have heard about Elon Musk’s handpicked CEO for X, Linda Yaccarino, and her disastrous interview with CNBC’s Julia Boorstin at Vox Media’s Code 2023 event. However, somewhat overlooked amid some of the more viral moments of the discussion, Yaccarino dropped some previously unknown stats that don’t exactly...

i’ve never really understood why they get so uptight about hair color and dress codes in general. is it just to maintain uniformity and control because they’re scared of change?

i’m not that stylish and personally don’t like the look of hair that’s dyed a color that doesn’t “show up naturally” (for lack of a better term), but it’s just my own personal taste and i think it’s important people are able to look and dress how they want. i also don’t like sports jerseys, but wouldn’t go around trying to ban those.

but it seems like these people get offended when they see people dress a way they don’t like, and their gut reaction is to make rules forbidding it. why? it seems like a lot of work that ultimately makes everyone miserable, when it’s much less effort to just accept that people are different and move on.

maybe he wants something in his pocket that he can bring up to say “see! i’m not racist!”. or maybe he thought it was a losing battle? (it would probably be extremely easy for a court to rule that a dreadlocks ban is unconstitutional)

according to this article, the law was introduced by a democrat and “sailed through both chambers of the Legislature with overwhelming support”. so that at least gives some support to the second hypothesis.

i haven’t seen one first hand but i can imagine such a scenario. this was a very good explanation, thank you.

what you said got me thinking a bit more about this and it’s made me wonder how much of this might be related to all the etiquette rules that people used to live by. i remember some of my older relatives getting visibly bothered if i held a fork the wrong way or put my elbows on the table, because it went against what they had drilled into their heads in classes when they were younger.

the ways i’ve heard the classes described make them sound like the teachers were very strict and were basically teaching children to be offended at behaviors that were “deviating from the norm” (for lack of a better term). i don’t know any people my age who attended etiquette classes, but my understanding is that it used to be much more common for older people.

i can’t help but wonder if the decreased cultural importance of etiquette is part of the reason people are more tolerant of different appearances. in some sense, they weren’t “taught” to be offended.

the problem is that making the line go up even a little gets exponentially harder with time. because the graph not going up at any given point in time is so unimaginably horrible to them, they keep having to think of new insidious ways of satisfying it
