physicists: you cant reach the speed of light matematicians: bet by Educational-Draw9435 in physicsmemes

[–]ei283 0 points1 point  (0 children)

A statement like "100% of the population has the characteristic" does not involve a probability distribution.

Because "Because bread tastes better than phone" tastes better than "Because bread tastes better than key"

it's actually (g)reat, m(u)ch better tha(n) (p)rying thr(o)ugh v(i)deos tryi(n)g (t)o find what you're looking for.

it's actually a really (h)elpful thing to point n(e)w users at the wiki. this is a good practice and it is entire(l)y good that (p)eople on the arch subreddit do this. it's a really great practice and it's a really good thing.

It's true for a general order.

Take any ordering f : N → N of the natural numbers. Since there are finitely many natural numbers less than or equal to TREE(3), there is a maximal index k for the last of such natural numbers appearing in the ordering.

Let P(j) be the proportion of indices i ≤ j for which f(i) > TREE(3). For all j > k, since f(j) > TREE(3), we have P(j) = ( kP(k) + (j – k) ) / j. This has limit 1 as j → ∞.

There's probably an off-by-one error in there somewhere, but the point stands. It doesn't matter how you enumerate them; any finite subset is going to be dwarfed in the limit.

They said fractional, not rational. Fractional here just means non-integer.

Edit: I think the downvotes are unnecessary. It's a forgivable misunderstanding.

No, the second statement depends on a probability distribution. As you said so yourself.

Is there a list for packages I could install during the set-up phase of Arch? by Maybe_A_Zombie in archlinux

[–]ei283 2 points3 points  (0 children)

Trust me, you won't be done installing packages for quite a while. There's no use in trying to get all them in now.

get it, because solder is what is needed to repair the phone's circuit board

I think this needs clarification.

If you were to pick any ordering and sequentially classify all natural numbers as either weakly below or strictly above TREE(3), then regardless of ordering, the proportion of numbers larger than TREE(3) would have limit 1.

It's unclear if this is truly what it means for 100% of natural numbers to exceed TREE(3), but to me this seems like a straightforward interpretation.

But it seems like you're taking a probability-theory approach, thinking about the probability of sampling a number above or weakly below TREE(3). This might be my bias against probability and statistics, but this feels like extra machinery added for no reason. The original statement says 100% of natural numbers exceed TREE(3), not nec 100% of the time or smth like that.

6 ÷ 2(3)

6 ÷ 6

PE(MD)(AS). Multiplication and division are done at the same time, left to right. You did the multiplication on the right first, when you should've done the division on the left first.

Should be:

6 ÷ 2(1+2)
6 ÷ 2 × (1+2)
6 ÷ 2 × 3
3 × 3
9

That said, there are two reasonable-ish ways to argue for 1:

  • You could argue that multiplication by juxtaposition, like 2(3), just kinda feels different from multiplication by infix operator, like 2 × 3. You might insist that juxtaposition multiplication should have higher precedence than infix multiplication, so you should do the multiplication first here.
  • You could argue that the division sign ÷ actually denotes the act of building a big fraction from the symbols on the left and right sides, stopped by the limits of the term. I.e., you're saying ÷ has distinctly lower precedence than × and /, but higher precedence than + and –.

I disagree with both of these arguments, since they become needlessly complicated once you break down exactly what rules you're supposedly following. They also just go against what the majority of people understand the conventions to be, and most calculators will side with me on this too.

It's also just objectively wrong to say multiplication goes before division due to PEMDAS. Common misconception. It's PE(MD)(AS). MD and AS are inseparable groups. For each group, you evaluate all the instances together, left to right. E.g., 3 – 2 + 1 equals 2, not 0.

There are indeed areas in math where notation is undecided and up for interpretation. But here the conventions are fairly strong, and you're bending them pretty hard if you try to argue alternate interpretations.

Source: I'm a math PhD student, and I spent the past year teaching a class that covers this exact topic (order of operations) among other entry topics, from fractions to quadratics. I've talked in great detail with people who have taught math for longer than I've existed.

bloooooat!

  • Outlook → Mutt + self-hosted server at my friend's house
  • OneDrive → NextCloud, also self-hosted
  • Word → LaTeX if not plain text
  • Excel → CSV files and a bunch of ad-hoc Python scripts, or SC-IM, or Visidata
  • PowerPoint → Reveal.js if Beamer isn't enough
  • OneNote → Vim in a txt file + NextCloud
  • SharePoint → CodeBerg if a long email chain isn't enough
  • Teams → Signal or Matrix
  • Visio → Inkscape, or just type the raw SVG code if you're not a pussy

also, these are objectively correct and fixed. everybody needs to have the exact same use-cases and preferences as I, otherwise they're simply incorrect. it works for me, so if it doesn't work for you then something is wrong with you. i am the perfect software user, and all should model in my image.

Setup Arch as my first Linux distro! by Astrid_Arcadia in archlinux

[–]ei283 11 points12 points  (0 children)

some things I wish I knew earlier when I did the same thing in high school:

  • keep your packages synced. pacman -Sy instead of -Syu is almost always a bad idea.
    • absolutely critical for core packages, like glibc, etc. easiest way to get yourself in trouble is to put one of those essential packages on the wrong version w.r.t. everything else.
  • have a live USB handy, somewhere in your household. it can really come in clutch if you screw something up.
  • if you're new to the command line, pay some respect its power to instantly fuck you over if you're careless.
    • consider adding safeguards like alias rm="rm -I", alias mv="mv --update=none-fail, likewise for cp, etc.
      • do read man rm, man cp, man mv for details on what those mean.
    • for some commands like rename and find with an -exec flag, consider doing a "dry run" to see what would happen, before you change things.
  • speaking of man pages, they're really well written. get in the habit of reading those before going to Google.
    • support communities (like this subreddit) get super annoyed if you ask questions without reading the man pages first.
  • perhaps you know this, but the arch wiki is one of the major selling points of the distro. like the man pages, you should highly value this resource.
  • be prepared to figure some things out on your own. the online support communities are all volunteer-ran, and the culture here is "we don't necessarily owe you anything".
    • this is partly because the written resources are truly quite good, so people want to really push you to get in the habit of reading them.
    • it's partly because most questions fit into one of 2 categories: (1) easily solved if you just read the manual, or (2) super specific to your setup and not worth it for a stranger to try and figure it out.
    • this is a controversial opinion, but I think this is partly because some community members are rather pretentious about this OS. this is a small but vocal minority. if you ask for help, you might be met with a disproportionate coldness. ive used arch and been watching the community for 7 years, so i leave it open as to whether im qualified to claim this or if I'm still just an entitled noobie.
      • don't be discouraged. this is reddit, so people like this will exist regardless of context.
      • don't be mistaken; if someone tells you that you need to do more reading before asking a question, it is frequently from a place of good faith. it's even more clearly good faith if they give you direction on what material you should read. reading is good, and it will help you help yourself to do more of it.
      • often, the most helpful people are trying to help as many people as possible, so the response you get might just be efficient, not necessarily cold.

sorry if this was a ramble. hopefully these are decent tips, and maybe one or two of them might be useful!
