- Comment on How come laptops or pc's don't have a "webcam" facing both ways instead of just the user? 2 days ago:
It’s just not as useful as the rear-facing camera on a phone or tablet. You can’t aim it easily, so it’s stuck pointing slightly downward at the surface it’s sitting on, unless you’re interested in making your screen harder to see.
Plus it’s more expensive for a feature that few people would find useful.

Well, currently Ball doesn’t make any jars, as I understand it. And I don’t think it’s in Muncie anymore either. So the term is just a holdover.

Those do look really nice, for sure. They’d make great snack cups.

Oof. I think I lean more toward her side, to be honest. I don’t like having cold hands.

Believe what you like. Including that all mathematics communication and education is flawless and incapable of any ambiguity, apparently.
But for your own growth as a person, I recommend you chew on this: the people who write these “questions” to put on Facebook are exploiting the exact same mindset that made you decide that insulting my intelligence was the best way to have this conversation, and using it to get a massive amount of rage-baity engagement. They’re not teachers trying to educate. They’re scammers trying to build up a following so that they can execute a scam.
Actual math educators, on the other hand, are moving away from using the “PEMDAS” (or “BEDMAS”) acronyms because of the ambiguity inherent in them, and using “GEMS” (or “GEMA”) instead. Partially because, if even smart people who know PEMDAS can get confused, the acronym must not be all that useful.
Anyway. You’re trying to make me mad, and for a minute it worked. But I’m over it. Again–have a good one.

Yeah, for sure. Though if you drink it fast enough, it won’t warm the drink noticeably before it’s gone.

Great at conduction, but with not a lot of thermal mass, meaning that actually your drink will usually just make whatever it’s touching (your hand, often) super cold or hot.
- Comment on Meanwhile Ball 2 weeks ago:
Muncie, Indiana is the home of the Ball Corporation, which is the company referenced in this meme. Also of Ball State University, founded by his endowment. Like “Mason jar” before it, “Ball jar” has become a genericized trademark for the object itself, especially in the Midwest.

I’ve been ad-free for long enough at this point that I feel physically assaulted when I see one (at a friend’s house or whatever). It’s insane that we ever thought that was ok, and it’s become worse.
At this point, adblock is a survival measure. Piracy is self-defense. The first presidential candidate who campaigns on legalizing graffiti on billboards and mandating their eventual removal gets my vote. Burn it all.
- Comment on Is gold investing a scam? 3 weeks ago:
Definitely a fair point. But for the most part, being in the country that collapses is going to be worse than being in a different country.
- Comment on Is gold investing a scam? 3 weeks ago:
This is just me, and I’m no expert. But I kind of think that, if you’re legitimately worried about your country’s currency collapsing, you might want to consider leaving your country. Any sort of collapse that leads to hyperinflation or the large-scale elimination of financial infrastructure is probably going to be difficult if not impossible for the average person to survive, gold or no.
That said, precious metals are a niche enough market that I can’t imagine it not being rife with predatory sellers; companies that aren’t offering scams per se—you’ll probably pay them and receive what you pay for—but companies which are counting on people not knowing anything about the market and accepting a terrible price or poor quality goods.
Again, not an expert. But my end-of-the-world investment would be in shelf-stable food, easily-stored seeds (for planting), medicine, hand tools, high-quality camping gear, books, that sort of thing. If there is a collapse, those sorts of things will be immediately useful and also tradeable.

I think part of what you’re saying is why the Kowloon build can’t deliver that, though.
- Comment on This Minecraft map that recreates, [Kowloon Walled City], one of history's most notorious slums made me reconsider what's important in 3D level design 4 weeks ago:
It’s a very good summary of the article. The things the author reconsidered were pretty nuanced, and trying to describe them in a headline without making the headline even longer than it is.
Would you have liked this better?
“This Minecraft map that recreates Kowloon Walled City, one of history’s most notorious slums, made me realize that 3D level design isn’t just about the complexity or the environmental challenge, but about the internal lives of the people who live there and the way that the game implies a greater reality that exists beyond the confines of the camera’s field of view”
Because that’s too long to fit in a tweet.

I read the article. It appears to deliver on the promise of the headline pretty completely. The headline also isn’t sensationalized or misrepresentative of the content. Are you just upset because it sounds a little bit like a LinkedIn status in its construction?
- Comment on Why do some Americans "feel ashamed" for being American even when it's not their fault? 4 weeks ago:
Speaking only for myself: because the American government has, for 250 years, claimed to act on behalf of the American people. When it was liberating concentration camps and sending people to the moon, that was something to be proud of.* When it was upholding slavery and winking at Jim Crow laws, it wasn’t.
It’s a government “of the people, by the people, and for the people,” and so he purports to speak and act on my behalf. That’s deeply embarrassing and shameful, even if I couldn’t have done anything differently to prevent it.

That…seems so obvious, now that you say it.
- Comment on Is it completely impossible to do age verification without compromising privacy? 4 weeks ago:
That’s not about Bob trusting Grace specifically (that’s a premise of the entire operation), it’s about trusting that the letter Alice handed Bob was actually signed by Grace.
- Comment on I dunno 4 weeks ago:
Well and truly noted. I was unaware until I got called out on it, so the whole experience has made me wonder how often I do that sort of thing without realizing it.
Pretty hypocritical on my part, since I’m usually on team hey-actually-read-it-before-you-comment.
- Comment on Is it completely impossible to do age verification without compromising privacy? 4 weeks ago:
That could very well work, yes; but I think that would require Bob verifying Grace’s signature, and that would require trusting that Grace didn’t make a unique signature that she only used for Alice, and making a note of who verified it.
There might be a way to verify those signatures with public keys in a way that didn’t require Bob to tell Grace that he was verifying the signature, which is still rattling around in my brain.

Are you kidding? I might actually stop buying new games and make it through my backlog now! This is great!
- Comment on Is it completely impossible to do age verification without compromising privacy? 4 weeks ago:
I’m inclined to say no. Reducing the problem down to its most basic parts: Alice is authorized to talk to Bob, but Bob doesn’t know that. How can Alice prove it?
Bob has to assume that anyone asking to talk to him could be Mallory, who isn’t authorized to talk to him but will always answer “yes” if asked whether she is. So the authorization he gets has to be from a trusted third party; it can’t come from Alice.
Grace is a trusted third party. If Alice doesn’t care about privacy, and is okay with Grace knowing that Alice talked to Bob and with Bob knowing Alice’s identity, Alice can just tell Bob, “here’s proof that I’m Alice. Show this to Grace and she’ll confirm that I can be here.” This is SSO, essentially.
If Alice doesn’t want Bob to know who she is, but is ok with Grace knowing that Alice talked to Bob, she can ask Grace to give her a secret code, and give that code to Bob, who can check with Grace to know whether or not that code corresponds to someone who is authorized.
If Alice doesn’t want Grace to know that she’s talking to Bob, though, she runs into a problem. Because there’s no way for Grace to send Bob a message without knowing who Bob is, he can’t ask anonymously, and because there’s no way for Grace to confirm that Alice is authorized without knowing who she is, Grace will always know that Alice has asked for authentication to talk to Bob.
Adding Dave in as a trusted fourth party could solve the problem—Alice asks Dave to check with Grace, and lock his answer in a bag with a unique key that only Dave has. Then Grace could give the bag to Bob, who doesn’t need to know who Grace is to pass the bag to Dave and ask him to unlock it. But Alice would be trusting that Dave won’t keep records on which bag corresponds to which person.
I don’t think that’s a surmountable problem. I’ll have to think about it some more.

Nope, you’re right. I just read the words and assumed it was one of the terrible ones.
This one is just…math.
- Comment on I dunno 4 weeks ago:
You’re right. I honestly just assumed it was one of those intentionally engagement-baiting posts when I saw it and didn’t even process the problem itself.

In fairness, this one isn’t nearly as bad as most of the ambiguous problems that get passed around on Facebook with multiple parentheticals and such.
Your word problem is excellent.
