>Fractions are like groups of pencils or tables of girls and boys.

No, they aren't. I can have a fraction like -1/3... what's a negative one-third of a table of boys and girls? I can multiply -1/3 * -100/3 and get a positive fractional value - if we're talking about tables of boys and girls - what the heck happened there? How about 1/0 or 0/1?

>Mathematicians have come up with rigorously defined approximations of them so that can work on them using formal methods.

I think you have it reversed. The formal definition is the pure definition, which is ancillary to the application to the real-world but covers much much more.
As someone who occasionally streams, max latency would be around a consistent 7-10 seconds - that makes some interaction patterns (the quick "which choice do I pick?") harder but still allows some reasonable level of feedback.

Part of the reason I personally watch streams is to feel connected to the rest of the audience - when something good happens we all cheer immediately, when something bad happens there's immediate commentary. Being split up from part of the audience would cause me to feel weird - as one of the vocal minority I'd be cheering in a much smaller crowd, and as one of the passive viewers I'd always be wondering what the vocal minority were on about.

There's also another type of stream that's popped up on reddit's RPAN - just random people chatting and interacting with their audience. That's not really feasible in Peertube's model.

Note that there's some types of streams that Peertube's model could be great for - pre-planned event shows without much interactivity, live captures of current events, and so on. GDQ, various music and performance events, broadcasts from protest zones, and so on could use this.
Actually, batteries win on refuel time. Swapping batteries is much faster than filling a tank. Gas wins on meantime between refuels and in other categories. Farmers can and happily will spend super long periods of time recharging if they can operate during the recharge.

My own initial experiences have been mixed. Overall advantage still goes to gas. But I think we're very close to getting this battery thing figured out. Just a few years away. When we look back it will seem like it happened overnight.
This is one of the reasons I annoy people by following Wolfram’s convention in Mathematica of using square braces to denote arguments passed to a function: f(x)=fx=f×x while f[x] means “apply the function f to the argument x”. An unusual convention it may well be, but at least it’s one devoid of ambiguity.
"Logging is a feature", as the authors of Growing Object-Oriented Software Guided by Tests state. As such, we need to treat them as we would treat any other feature. One relatively straightforward way of adding logs is by decorating your objects. Logging decorators.

For example, if `Client` is defined as an interface, we can have two concrete implementations. One that holds business logic – `NetClient` – and one that holds logging/developer logic – `VerboseClient`. As we inject dependencies, we can compose a client like this: `NewVerboseClient(NewClient())`. This way you may even test you logging logic by composing it with different implementations of clients (one that always fails, for example) to test the different kinds of logs.

I kind of don't like how "lolicon" is being used -- because pedophilistic orientation don't seem to correlate all that well to how likely people is banned from Twitter. There's a real pedo guy on it, who I've seen public about how arts don't substitute stuffs, who posts his... arts a bit jagged, and doing it for years, then on the other hands there are artists getting banned nth times this year posting an abstracted person with clean and continuous lines.

My theory is there's a set of curve parameters that evaluate to "legality" in a sigmoid response that has less to do with ages or even if it's depicting a human or an animal or not, like a picture of desert hills looks pornographic sometimes or how sumo wrestlers charging evoke no sexual emotion. That human curve scoring yet to be discovered is, to me, looks like how legality is determined worldwide on and off internet, so calling those drawings as loli or people doing those curves as lolicon is inaccurate in my opinion.
Not really in the market for one, but in the US the 2019 Hyundai Ioniq (range of ~120 mi, so not ideal if you don't have a charger at home) is $99/mo with $1000 down for a 3 year lease, which is dirt cheap. I'm guessing after three years the battery will still be valuable, so they can be aggressively pricing it this way.

I think if Tesla had better leasing, you'd see way more of them

Running old binaries is absolutely routine in production systems. You're just saying that no one would write new code to use this, and that's true.

But to Intel, refusing to support that stuff means that no one will migrate their existing system running some old 32 bit code to a modern cloud system, and that's lost revenue.

You may find this hard to believe that but there is very little evidence that masks work for this particular disease,

The group think is strong with the masks - but in reality, the scientific evidence is scant and inconclusive at best. This is why CDC never recommended them in the first place.

There are a large number of people that put all their faith in masks, because what else is there? They fervently hope and really want masks to work. And I understand that I wish masks worked, but do they really? The scientific evidence is just not there.

This post will be heavily downvoted for the same reason. It is a psychological thing. When they put on the mask people feel like they are doing something.

People strongly believe that masks HAVE TO WORK it just MAKES SENSE THAT THEY WORK, HOW COULD MASKS NOT WORK?, in reality, the evidence is not there. Masks feel to me like a superstition or flat earth belief. Where is the evidence?

Questioning the efficiency of masks is heresy, you'll get banned from Youtube or Facebook for questioning masks, but not for questioning vaccines or for promoting vitamin C as a cure for cancer ...

Why is that? Because there is no evidence, if there were you'd be pointed to that.

Funny to see this thread to be complete opposite with a lot of praises, e2e discussions and mastodon onboarding.

I feel that Mr. Gargron has been his own worst enemy at times. Mastodon.social instance is notoriously bad, overmoderated and often down-right abusive.
While Mastodon itself in many ways a brilliant project with great dev team and direction it's that just they seem somewhat socially inept/extreme at times.
This is why I taught my kids to label units.

( 1 girl / 3 students at table L + 1 girl / 3 students at table R ) can't be added, because the denominators are different.

To fix that, you can multiply by the factors ( 3 students at table L / 6 students at both tables ) and ( 3 students at table R / 6 students at both tables ) so you get ( 1 girl / 6 students at both tables + 1 girl / 6 students at both tables ) = ( 2 girls / 6 students at both tables ).

To hammer it home, you point to the table that has 2 or 4 students at it, and ask someone how to add the proportion of girls at that table to the two already under consideration.

“Exponentially higher” can refer to magnitudes, not growth. If I have $1000 (10^3) today and $100 (10^2) some time ago, I have exponentially more dollars now than then even if that value grew linearly over that time period and continues to grow linearly. I won’t have exponentially more over the next time period, because it’s not growing exponentially, but it’s still correct to say at that point my bank account is exponentially higher.
I do everything with the keyboard in VS Code, in normal, non-vim mode and it's way better than vim. What vim does when you type out entire command sequence words and patterns, VS Code lets you do with a single keystroke or chord.

In VS Code there's also no hidden mode with zero discoverability on how to exit it. And it's easy to configure VS Code with new extensions that you can find and install right in the program, while vim will have you searching blog articles to find the right plugin manager and plugins to manually download and configure - what a hassle.

There's absolutely no reason for modern programmers to learn vim.

>We didn't invent fraction out of nowhere.

But we did. When mathematicians provided a rigorous definition of fractions (rational numbers) they separated them from the real world. Rational numbers do not exist in the real world. Real-world does not have infinities. It does not have negative values. In the real world 1/3+1/3 does equal 2/6 in the way that the fourth-grader applied the analogy.

>The moment where you have to stop relying on intuition is a pretty delicate matter

I didn't argue that metaphors and analogies shouldn't be used. I argued that analogies and metaphors are intrinsically flawed and this article provides a great example. At some point, you have to give up on the analogy and fallback on the underlying axioms. You can't do "1/3+1/3=2/6" not because it doesn't make sense for tables of boys and girls (because it does) but because it's against the rules for adding fractions.
I think we should call two points that are separated by more distance than the first point squared. For something to be exponentially away from something else, it would have to be at least itself squared. So 26 is exponentially far from 5 (5^2).
Outside of Linux Desktop, the operating system and applications are considered separate beasts, so you're able to have a stable OS and a mix of stable/up-to-date applications as you see fit.

The package manager/distro model that Linux employs only ever seems to give you the choice of one or the other, because it doesn't have a clear differentiation between "OS" and "application".
Obsession does not mean religion. I can't believe such drivel makes it past the Atlantic's editorial. Does Qanon have any unique belief that describes how the world came to be? why people exist? what the purpose of people is? What happens when you die? What the correct way of living is? Even a cult thinks their leader knows all these things.

I mean come on, you can't be sillier that Qanon when trying to do discredit them. I hate partisan propaganda so much,it thrives on intellectual dishonesty.

Qanon is a social movement,ideology,cultural phenomna and other things. Much like the teaparty movement a few years ago (one can say it evolved from it).

Of course I personally think it is something people who hated Obama rallied around. A social movement to promote modern xenophobia and racism and implement fascist rule in america and the west. Perhaps a Russian thing. (Reminds od this bad guy speech from "The sum of all fears" : https://youtube.com/watch?v=Wzp2rpe06j8)

That's a terribly poor argument.

> With 39.26 deaths per 100,000, Sweden's mortality rate is not only higher than that of the U.S. (29.87 deaths per 100,000) but also exponentially higher than those of its neighbors Norway (4.42 per 100,000) and Finland (5.56 per 100,000)

Every country has variables. The USA is handling things pathetically and still has a far lower rate than Sweden.

Sweden goofed, that's a fact.

*Edit: To the people giving me shit, I am pointing out that this commenter is using a strategy (I don't know if there's a formal name) to tangentially push an agenda. 1. Sweden did the right thing, and 2. Brown people are 'invading' Sweden.

Personally the idea to sacrifice anybody's life for 'quality of life' or 'economy' is bullshit. Western governments all had the resources to help more than they did.
Shame, really. I love distributed P2P applications built around dumb, simple techniques or tools. Super complex abstractions are useful but as a project creator it's difficult to rely on new technology if you can't support it yourself.

It depends on the context. As an intermediate step I definitely write things like x (3) meaning multiplication, as it can more clearly indicate what's just happened (see my other comment in this thread).

There's other context too, based on what is known. Up to a certain point in first year at my university, most engineering students haven't ever seen functions named x and y, and so they'd mostly interpret x(3) as multiplication. Then we show them parametric curves, and suddenly x(3) looks like the x coordinate of a point on the (x(t), y(t)) curve.

Do you see how absurd it is to present an anti-racist slogan and a racist slogan as equivalent? Your logical contortions require the removal of all context from the discussion. Context is important. In this case, the context is that the overwhelming majority of this phrase's usage is as a white nationalist slogan. You're deliberately ignoring this in an incredible attempt to paint anti-racist activists as equivalent to racist activists.
This is done by some apps today, though the motivation was typically network perf (http2 and then QUIC support). The stacks are large - on iOS it's difficult to take over a portion of networking without rebuilding a substantial amount of it, so you'll have TLS, a full http stack, plus all supporting logic for connection pooling, etc.
The closest thing to an open-source, drop-in option like this is cronet, the networking core of chromium packaged as a standalone library. Last I looked it was multiple megabytes in size, which is still a substantial cost for iOS apps. They can also be quirky to use because they fight against the system's defaults in some areas and can cause other inefficiencies (typically outweighed by the network improvements).

I believe Uber talked publicly about adopting cronet, and Facebook gave a talk about mobile proxygen (though it is not open-source). If you pop open the Netflix and Youtube apps, you will likely see the same.

Every node on a local network would need to be able to know whether another node is on the local network (unless you want all traffic to go through a router). So do you send arp requests for every ip you try to contact? Distribute a list through DHCP?

All upstream routers needs to know about your node. So every time someone somewhere in the world connects a new device a message gets sent up to the core routers of the internet? And the core routers needs to keep track of routing tables in the size of billions and be able to look entries up in nano seconds.
