unkown-unknowns··on Can a Living Creature Be as Big as a Galaxy?
Sure but my past selves are also part of who I am. Without them I would not be me, and so I think they are more me than not me.

I think the delay is due to Twitch itself.

I am quite stupid, I always thought that when people on HN talked about their weekend projects they meant something that they'd made in a single weekend. Only now upon reading your comment do I realize that it means something one is working on over any number of weekends. I've been on HN for about 7 years :/

All this time I've been wondering why it takes me weeks of weekends to complete what others do in a single weekend even though I regard myself as highly competent at both software engineering and programming. Then it turns out I had simply misunderstood the meaning of "weekend project".

Oh and also, very nice project, kudos.

Why not? I would.

I use dc every now and then but I wish it'd do decimal math by default.

    9 35 5 12 *+/p
Furthermore I think it's strange that the order of the operands of the division operator is divisor as top-most value on the stack and dividend as second top-most value and not the other way around.

For example, to me it'd feel more natural if

    3 5 /p
was equivalent to

    5 / 3
in infix notation, not

    3 / 5
Because when I think of a fraction I think of it as "dividend over divisor".

Edit: Actually I Googled and it makes sense now. I've been focusing on what's on the stack but if we look at what is provided as input instead then it becomes "calculate dividend, calculate divisor, divide". Longer example which shows this:

Algebraic expression

    (4 + 2 * 5) / (1 + 3 * 2)
RPN

    4 2 5 * + 1 3 2 * + /
unkown-unknowns··on Malicious crossenv package on npm
I wonder how it was detected. Also someone ITT said something about if they'd squatted the dependencies it wouldn't have been seen or something? Can't find back to that comment.

Like sibling says, doxxing implies that you'll post their personal info online.

The problem does not lie in attacking bad people, the problem is that there is a high risk that you THINK you've identified who the bad actor is but actually the person you decide to "retaliate" against had nothing to do with what was done to you. That's why we leave law enforcement to the law enforcement officials and justice to the justice system. Even they make a lot of mistakes but at least there is a process that gives a chance for the truth to be found.

But sharing info about a suspect with law enforcement is what you should do yes.

Whose NPM account? If you mean the attacker it was removed by the NPM people after it was reported.

No that's not good. Do scope but don't make package names unique.
unkown-unknowns··on Is Amazon's cloud service too big to fail?
There are some open source implementations of parts of the APIs of cloud providers that might help someone a bit when trying to migrate. For example, Minio [1] [2] implements the AWS S3 v4 API.

But will you hand over the private keys for the wallets your customers have with you so that they can use the BCH, or will you only transfer money to another BTC wallet and so the ship has sailed?

> the trash company is the same as the recycling company, so it's very likely the recycle (at least some portion of it) ends up in the trash

No that doesn't make sense. If they didn't care about recycling why would they make people sort their trash in the first place?

unkown-unknowns··on Show HN: Compile-time HTML parsing in C++14
Even though it's not the real machine it's still a lot closer to it than you get from the higher level languages mentioned by parent commenter like they said.
unkown-unknowns··on The digital native is a myth
Yes but when done correctly it also brings a lot of value to their employers so it's a win for both sides.
unkown-unknowns··on The digital native is a myth
I agree completely.

I sometimes think that perhaps the myth of the digital native generation arose because an insanely high percentage of the population is so illiterate with computers that they think that just because the kids are spending all of their time in front of screens it means that those kids automatically "understand" computers when in fact they are just learning very specific applications of computers.

I also think it's a bit of a cop out on their part (not sure that it's the right word). The computer illiterate are so turned off by the idea of trying to understand computers that they will gladly throw compliments at any kid just so that the kids will shut up about anything relating to computers. "Oh ho ho, I'm so old you know I don't know anything about them computers and phones and what have ya. But you kids, you grew up with these things, so to you they are second nature."

Edit: Sibling commenter about millennial vs gen z has a good point. Still I think that it's mostly those of us that made an effort to learn that it goes for though, just like with the people that grew up before that with home computers.

When you say as bullet point, do you mean as in before the text? That's not how to use emoji in general. But a single emoji at any place within the text (as opposed to many of them) is a good idea.
unkown-unknowns··on The confusing way Mexicans tell time
I enjoyed the article and I think that someone who's going to travel to Mexico and don't know anything about the country might find this article useful.
unkown-unknowns··on Netboot Linux over the internet
> Lets you do things like make RAM only Postgres databases servers, or run your web server applications purely from RAM without any login, for speed and security.

Holy crap, I've been wishing for this for a long time! Thank you very much for creating this!

But even though the protocols are big endian, is it generally the case that you always make the data itself big endian? (Asking out of ignorance, not rhetorically or sarcastically.)

Nope, accidental.
unkown-unknowns··on Ask HN: Protect loved ones from online scams?
However you can still check the IP address of the mail server that sent the mail. Some things to look at:

1. Check PTR for IP and verify that the A or AAAA record for that name points back to the same IP.

2. Compare with IP address of server that sent previous mail to you.

3. Check SPF records for the domain.

4. Check MX records for the domain. Keep in mind that they might be using different servers for sending than for receiving though and that MX is for receiving.

But for his own sake wouldn't it be better you told him so that he can either get a burglar proof safe if that's what he wants or get a new fireproof safe that he then doesn't destroy by drilling through it?

I know that a lot of people don't appreciate advice though, but still if this relative respects you they should listen.
