Driving 8 hours round trip today to pick up one person, and I'll never understand why Americans think this is more convenient than my colleague taking a train.
In America the train costs as much as a plane ticket.
While this is often true, I think there’s a habit of comparing apples-to-apples, when they are not the same. Getting to/from the airport is often expensive while train stations are commonly in convenient downtown locations.
Driving is cheaper.
Again, I feel like a lot of people over simplify and just go, “My gas is X, the train ticket is Y. X<Y, so driving is cheaper.” It completely ignores maintenance costs and depreciation, which are a lot more than people give them credit for.
Again, I feel like a lot of people over simplify and just go, "My gas is X, the train ticket is Y. X
I don’t think it is an oversimplification honestly. It might work out as a favorable arrangement if we’re only talking about only moving around within a larger city with robust infrastructure, but the scenario of the post with a 4 hour drive speaks to the fact that this isn’t the case.
For driving a fair distance your expenses will be gas, tolls, and parking generally. A long-range train ticket will likely cost more than all those combined and then on top of that you’ll still likely have to pay for extended parking and/or other transportation on one side of the trip if you don’t have someone you can rely on.
I don’t by any means live in the middle of nowhere and the nearest train station to me is still over a two and a half hour drive. I don’t enjoy it, but the infrastructure just isn’t there to make this a feasible option for many people.
No, the test itself is definitely the problem. Regardless of whether you believe a personality type test can be effective, the MBTI is particularly and provably ineffective in just about every measurable way:
It’s not reliable. It has terrible test-retest reliability. If I’m X personality type, I shouldn’t test as X type one time, and Y type the next, and Z 6 months laters.
It’s not predictive. If a personality test accurately judges someone, it should mean you now know something about someone’s behaviours, and can extrapolate that forwards and predict behavioural trends. MBTI does not.
It fundamentally doesn’t match the data. MBTI relies upon the idea that people fall neatly into binary buckets (introverted vs extroverted, thinking vs feeling, etc). But the majority of people don’t, and test with MBTI scores close to the line the test draws, following a normal distribution. So the line separating two sides of a bell curve ends up being arbitrary.
And finally, it’s pushed very hard by the Myers-Briggs foundation, and not at all by independent scientific bodies. copying straight from wikipedia:
Most of the research supporting the MBTI’s validity has been produced by the Center for Applications of Psychological Type, an organization run by the Myers–Briggs Foundation, and published in the center’s own journal, the Journal of Psychological Type (JPT),
I notice programming stuff leaks into my thinking and writing often but I actually enjoy the various constructs that help clarify thinking. I don’t have any formal background in logic tho :(...
Well maybe this is too basic but here are the most important to me:
formal implication:
X ⇒ Y (X implies Y)
means that if X is true, Y is also true. Note that the reverse is not necessarily true, Y being true does not mean X is true (or that X is false). There is truly a staggering number of people who make this mistake in thinking all the time. And If X ⇒ Y and Y ⇒ X then X ⇔Y (X if and only if Y).
Understanding ∀ (for all) and ∃ (there exists) is also very valuable.
Understanding these concepts is enough to understand the basic notation of a lot of math, with it you can start reading basic math papers and really expand your horizons.
It said that Google put it in their aggregated report. Not that they disclosed it. There is a big difference between ‘we got 100 requests’ and ‘we got 10 requests for X info, 30 for Y info’.
ETA: I just looked at the data again, it’s broken in to categories like FISA NSL etc, then it just gives a range of requests 0-1000 etc.
I’m not putting too much hope into this. People have been saying the Russian economy would collapse soon because X and Y since the beginning of the war, and so far it has resisted all threats. I’m sure they are operating on borrowed time, but I’ll believe in a collapse when it’s actually happening.

I’m currently working on a FOSS Discord bot. When I host an official instance of said bot, do I need a TOS and or Privacy Policy, or is a link to the license (in my case GPLv3) enough?...
Disclaimer: also Hobby person but did some more reading on that topic in the past. . Think about what those things are then decide:
The tos are your conditions: I as provider of this service will reserve the right to x. When a user does y I will do z. It’s cover your ass for businesses.
A privacy policy on the other hand might be required by law as soon as you process user data in any way. This is something that I would look into your jurisdiction and their requirements. I’d guess Germany is more on the formal side on things (clichés and everything)
In short: you don’t need a tos but most likely want one. You don’t want a privacy policy but most likely need one. :)
lol, math is literally the only subject that has rules set in stone. This example is specifically made to cause confusion. Division has the same priority as multiplication. You go from left to right. problem here is the fact that you see divison in fraction form way more commonly. A fraction could be writen up as (x)/(y) not x/y (assuming x and y are multiple steps). Plain and simple.
The fact that some calculator get it wrong means that the calculator is wrongly configured. The fact that some people argue that you do () first and then do what’s outside it means that said people are dumb.
They managed to get me once too, by everyone spreading missinformation so confidently. Don’t even trust me, look up the facts for yourself. And realise that your comment is just as incorrect as everyone who said the answer is 1. (uhm well they don’t agree on 0^0, but that’s kind of a paradox)
They’re still wrong, in my humble opinion. I’m aware of this notion, and I’ve even had people share a snip from some book that states this as fact. However, this is not standardized and without the convention being widely understood and recognized as the standard in the world of mathematics (which generally doesn’t use the symbol (÷) at all at post-algebra levels), there is no reason to treat it as such just because a few people assert it is should be.
It doesn’t make sense at all to me that implied multiplication would be treated any differently, let alone at a higher priority, than explicit multiplication. They’re both the same operation, just with different notations, the former of which we use as shorthand.
There are obviously examples that show the use of the division symbol without parentheses sometimes leads to misunderstandings like this. It’s why that symbol is not used by real mathematicians at all. It is just abundantly more clear what you’re saying if you use the fraction bar notation (the line with numerator on top and denominator on bottom). But the rules as actually written, when followed, only reach one conclusion for this problem and others like it. x÷y(z) is the SAME as x÷y*z. There’s no mathematical or logical reason to treat it differently. If you meant for the implicit multiplication to have priority it should be in parentheses, x÷(y(z)), or written with the fraction bar notation.
So 1/2x is universally interpreted as 1/(2x), and not (1/2)x, which would be x/2.
Sorry but both my phone calculator and TI-84 calculate 1/2X to be the same thing as X/2. It’s simply evaluating the equation left to right since multiplication and division have equal priorities.
X = 5
Y = 1/2X => (1/2) * X => X/2
Y = 2.5
If you want to see Y = 0.1 you must explicitly add parentheses around the 2X.
Before this thread I have never heard of implicit operations having higher priority than explicit operations, which honestly sounds like 100% bogus anyway.
You are saying that an implied operation has higher priority than one which I am defining as part of the equation with an operator? Bogus. I don’t buy it. Seriously when was this decided?
I am no mathematics expert, but I have taken up to calc 2 and differential equations and never heard this “rule” before.
For example, if f(x,y)=x2+yx, then (∂f/∂x)y=2x+y, and (∂f/∂y)x=x. We can extend this idea to higher derivatives: ∂^2f/∂y^2 or ∂^2f/∂y∂x. The latter symbol indicates that we first differentiate f with respect to x, treating y as a constant, then differentiate the result with respect to y, treating x as a constant. The actual order of differentiation is immaterial: ∂2f/∂x∂y=∂2f/∂y∂x.
Notice: ∂^2f/∂y∂x is clearly written to mean ∂^2f/(∂y∂x).
What an interesting error to point out in support of pemdas.
Clearly the formatting of a paragraph of text in a textbook full of clearly and unambiguously written formulas discussing the very order of operations itself compared to the formatting of an actual formula diagram is going to be less clear. But here you’ve chosen to point to a discussion of why the order is irrelevant in the case under question.
Your example is the conclusion of a review of mathematics.
First we shall review some mathematics.
…
The actual order of differentiation is immaterial:
The fact that the example formula is written sloppy is irrelevant, because at no point is this going to be an actual formula meant to be solved, it’s merely an illustration of why, in this case, the order of a particular operation is “immaterial”.
Even if ∂^2f/∂y∂x is clearly written to mean ∂^2f/(∂y∂x), it doesn’t matter because “∂2f/∂x∂y=∂2f/∂y∂x”. So long as you’re consistently applying pemdas, you’re going to get the same answer whether you derive x first or y.
However, when it’s time to discuss the actual formulas and equations being taught in the example text, clearly and unambiguously written formulas are illustrated as though copied from Ann illustration on a whiteboard instead of inserted into paragraphs that might have simply been transcribed from a lecture. Which, somewhat coincidentally, is exactly what your citation is.

Legally, if I tell the government to call me by X name and use Y pronouns, they must respect it.
Rapheal “loves-the-feeling-of-freshly-pissed-pants” Cruz, or as he is most commonly known, Piss Pants Cruz, doesnt like mandating respect for an individuals preferred form of address.
I’ve talked about it with people who are not rich themselves but who are around the mega rich because of their jobs… Apparently at a certain point, “things” lose their meaning and experiences become their new materialism. Hence why so many rich people get caught up in depraved shit that makes it on the news, because theyre down the rabbit hole of collecting wild experiences as opposed to cars or jewelry or whatever other entry level rich person stuff. Flexing becomes more about “have you been to x, have you done y” etc
GUI and CLI are tools, both with separate advantages and disadvantages.
CLI let’s you chain different commands easily to create functionality that originally wasn’t there. It’s really flexible, but it’s also very non-obvious. Even after more than a decade of Linux usage, I still find new commands I have never heard of that do exactly what I wanted to do for a while.
GUI is great for visual stuff (nobody in their right mind would do video/audio/image editing on CLI). It’s also very obvious/explorable, so you tend to find functionality much quicker. That makes it great for any tools that you don’t use on a daily basis. And GUIs can utilise the bandwidth of human visual input much better, which makes them better whenever large amounts of data are presented.
Neither CLI nor GUI are better, they just have different use cases where they are better.
And it annoys me a lot that people don’t get that.
When you say “X is better than Y”, you always need to state for what it is better.
