Question: Computing Messages per Second
I'm trying to rationalize this in my head, any help is welcome.

"1 million individuals, each participate in 3 text message conversations per hour.

Each text message conversation involves 6 text messages over a 300 second (5 minute) period.

You are designing a system to handle this load. What is the number of text messages per second being generated, why?"

Here's my reckoning

1 million x 3 text conversations/hour x 1/3600 x 6 messages per second

But, that doesn't reflect the fact that each exchange lasts 5 minutes and therefore each text conversation only produces 1 text message per minute.
> what does it mean to be strong? is it without weakness? or the strength to acknowledge that weakness. If you're so strong you never cry is that really strength?

To be strong is to know that society will pull you down if you don't react with the same or more strength. I'm talking about men that don't have rich and/or protective parents, which is most of us, afaik.

> being dominant sounds like a good idea but once you think about it, it seems a bit absurd. everything humans do well we do as a team. being dominant only means you can be in charge of a team and not a supporting part.

There is so many roles in society still to be fulfilled. Social dynamics are this: dynamic. Someone might be in charge of one interaction but play a supporting part in another. I don't see any incongruence on this.

> and lastly success. What is success? is it just money? that's hardly a good measure. is it to be happy? and if that comes at the expense of not being "strong and dominant" then what have you left?

There is no need to fix the discussion around the 3 adjectives used in the article, but does it really make sense to question that men want to be successful? Not even this can be just simple acknowledged?

> You're describing a fantasy, an archetype and it does you and men in general no favours by striving to be something so ephemeral.

The article described. I just asked why not?

I had been working as a web dev (full stack) for some years, so the freelancing gigs I found were mostly web programming. One gig was for my ex-employer, other one was for other company. Of course you need to have some selling skills as well and know some people who need to do business.

During that time app stores were a relatively new thing, so the products I was developing were apps. They started making a decent revenue after 2 years if I remember right. The first year I didn't make about any money. I had very low-cost lifestyle, and cheap rent in a tiny apartment, which helped a lot. If I would have kids or some expensive hobbies it would have been much, much more difficult.

Having a big screen is so nice. The 17” MacBook Pro is the second best computer I ever had, after my current Thinkpad T530. If I had to buy a new computer today (hopefully not, as my Thinkpad is still going strong at five years old), I’d probably go for the P70.

I don’t mind having a big and heavy laptop though. I carry it in a backpack, and a few pounds more or less on my back is pretty insignificant.
Why the keyboard layout? End next to up key? Insert above backspace? What's wrong with the classic 2x3 block?

> The numbers are supposed to based on the child generation. If the numbers were based on the parent generation ("likelihood of passing down job preference") then a growing field should indeed increase the likelihood.

If we denote the event "Child is a programmer" by C and the event "A parent is a programmer." by P, then the sentence "Computer programmers have parents who are computer programmers at a rate 6 times the rest of the population." can be expressed in terms of probability as P(P|C)/P(P) = 6. Bayes' rule tells us that P(P|C) = P(C|P)P(P)/P(C), so the sentence is equivalent to P(C|P)/P(C) or "Parents who are computer programmers have children who are computer programmers at a rate 6 times the rest of the population."

It doesn't matter whether you are looking at the child generation or the parent generation, the heritability relative to the general population will come out to the same number. A growing field may increase the P(C|P) part of the ratio, but it will also increase P(C) in general, so it is not clear whether the relative measurement will change at all, and in which direction.
I thought your statement was rather aggressive (you basically say that the linux brand is used to bump the price), until I saw this :

Your backend should be double-checking any escaping the frontend does.

Does anyone know why the last two lines in main() fail? AFAICS, v has the same type as both functions.

fn try_option_some() -> Option<u8> {
let val = Some(1)?;
Some(val)
}

fn try_option_none() -> Option<u8> {
let val = None?;
Some(val)
}

fn main() {
assert_eq!(try_option_some(), Some(1));
assert_eq!(try_option_none(), None);

let v: Option<u8> = None;
assert_eq!(v, Some(None));
}

One other thing troubling me here - shouldn't try_option_none() return `None` and not `Some(None)`?

Looking at the diff for the commit, there's now a NoneError? Is there any documentation updates to look at how this works? Because AFAIK, now all matches will have to explicitly be updated to check for NoneError, otherwise they won't compile (since matches are not complete)?
4 months savings is nothing in self-employment or for freelancing.

A million things can happen that delay payment and sales coming in. A year to keep personal and businesses cost running is a good and sane minimum that also keeps your mind from the worries you get when suddenly alteady 2,5 of these 4 months are gone and another expected positive sales/payment event didn’t happen for whatever, maybe accidental, reason.

(Says a 10 year running freelancer who started with 12 months savings and currently runs on only 5 for some events in the past 2 years - but luckily with good project and customer base)

I am not a battery expert by any means. But the article says:

Isn't megawatts the measurement of power? Wouldn't Watt Hours be the measurement for capacity? Sometimes people use Apmere Hours also. Like the Chevy Bolt has 60 kWh of capacity.

Yep, I think that ipfs, being peer to peer, would be actually negatively affected by p2p traffic being in the slower lane. Globally.
"We should all be asking ourselves where such big distrust is coming from."

Well, I would say it starts with basic things early, like Santa Claus brings the presents. Later you find out, oh a lie.

And so on with many things. Church, all loving god, nice and caring government, war only for peace, health corporation's only make good medicine, etc. etc.

And then things like Kennedy and 9/11. I don't know what happened and I also don't care so much, but the more I looked into it, the less convincing became the mainstream truth.

Or less controversial lies, like weapons of mass destruction in Iraq and so on.

No wonder people then start to believe in more goofy things like the moon landing hoax, or climategate - or ultimately, flat earth.

They have just been lied too often by their authorities. And then make the stupid assumption, everything opposite must be true then.

You should be careful with that -- you can get nastier IP agreements through consulting firms than you might at full-time employment.

Similarly, even if it's not in the contract, you probably want your contracting work to be fairly orthogonal to your side projects, so you don't get sued for something by a client. It never looks good if you work on say, a networking project, and then a month later, your networking related product appears on the market.

Exactly this. In fact, even if you support NN, you should oppose Title II NN. It literally does the opposite of what NN supporters think, plus it allows strong government regulation of the internet.

I’m oppose to NN on principle (because it goes against the basic operation of the Internet and restrict innovation), but I’d much rather see a modern law passed than A law written 80 years used to implement it.

Average salary before taxes for all jobs is about $1000. Developers are paid about $1500 to $2500 gross on average, so my salary (about $3400 gross) is about the absolute maximum you can make before jumping to a manager/architect role (which are really scarce).

Quality of life is good but cost of living is also surprisingly high - about the same as in a city not in the US coasts, and the extremely high taxes cut into the chance of savings.

Real estate is very expensive (according to Numbeo, 50% higher than in most of the US) and there's no easy access to mortgages (interest rates are ludicrous, you need at least 20% of the property cost up front, some expensive overhead too).

The one huge benefit is healthcare being both cheap and REALLY good (the kind of service only very rich people get in the U.S.).

From https://en.wikipedia.org/wiki/Hornsdale_Wind_Farm the battery can do 70MW for ten minutes and 30MW for three hours. They also say "capable of discharge at 100 megawatts" but that might be margin of safety.

I wonder if things are limited by cooling? Maybe the battery only has enough cooling to sustain 30MW of output and doing 70MW for ten minutes is all heat soak.

I'm pro-net neutrality and I'm against dishonest marketing, but I think overall it's important to take the higher ground and remain intellectually honest. Doing otherwise results in a mud-slinging contest.

Existing regulations are a restriction on the freedom of service providers. That is undeniable. There many cases where we restrict freedoms for the greater good, but I don't like to pretend we are not doing so in those cases.

I'd also add that freedom is not the right to demand other people give you something you want. I wouldn't say that I've lost my freedoms if there are no good ISPs left after the regulatory change. Everyone involved can still either choose an existing provider or set up their own. We have monopoly/anti-trust laws when that ceases to be the case. Of course, this may not be the efficient path to a world that a huge majority of people want - which is why I slightly side with net neutrality.

> But if having 6 or 12 months worth of savings is a requirement, then you can rule out just about everyone except rich kids and upper middle class teenagers.

If you’re a good Software developer and have no idea how to save some 20-30k bucks in 2-3 years for your plan of your own business you’re doing something wrong.

Like you are bad at contract negotiations, no good contact network in the industry to find someone willing to pay for good people, have too high expenses, too low saving potential, or, you’re just not as good of a dev as you think.

Any of those should be reason enough for you to think again about your plans.

Not a few of those people, assuming they hear this story, will come away from it with a vague idea that those space and rocket guys aren't really all much that in agreement about the round-or-flat thing.

There's a term in the industry that's used for the amount of sugar that makes a food tastier/more addictive while not making it too sweet, don't remember what it is though. But yeah, it's like you said, they add it to everything to make it better tasting and more addictive.

There was some lab-rat study super long ago where they got mice/rats addicted to sugar and cocaine, then let them pick between the two - and they chose the sugar every single time.
I wouldn't call this distrust but an extreme level of skepticism. I think being Skpetic means you're not supposed to believe anything just like that and always be willing to see the other side of the story in fact believing the there is another side to this story.

But like every philosophical and religious institutions getting extreme believers and followers, Science Skeptics have also reached that point.

This is very much like an Atheist seeing Atheism as a religion itself. Being Skeptic also means you gotta be ready to fix your belief when you get an alternative that could seems rational or right, if you are not ready to do that, you are not a skeptic

100 hours a week is an insane amount to work. Depending on how much you sleep each day (and working this much is going to mean you'll end up sleeping longer) that's probably going to leave you less than than 3 hours each day to travel to/from work and eat. It doesn't matter how much passion you have for something, the majority of the population is not going to be to do this without slowly killing themselves.

60 hours per week is far more feasible (if you have few obligations outside of work), but I think that once that number starts increasing the number of people physically capable of working that long is going to drop very sharply.

As the error says,

found type `std::option::Option<std::option::Option<_>>`

The return types of those functions are Option<u8>, but Some(None) is an Option<Option<_>>.

> there's now a NoneError?

It's not stable yet.

> now all matches will have to explicitly be updated to check for NoneError

NoneError only comes into play when you have a function that returns Result, but uses ? on an Option in the body. That code never compiled (and still doesn't on stable until Try is stabilized, and only if you have Result<T, NoneError> as your return type or some Err type that implements From<NoneError>, which you also can't write until it's stable.

Does that help?
Exactly that! :)
