Venture Capital and consulting businesses are incompatible by nature.

Venture capital is about scalability (i.e. cost per unit goes down when number of units goes up - preferably considerably...)

Consultancies are unscaleable business by design, because they sell "hours". Every employee can deliver a certain number of hours only, so per-unit (marginal) cost is flat.

And therefore VC and consultancies does not match... at all..
Usually they care more about internal things than outside. See China.
Pizza slices. Different sized slices. Fractions of a pizza.
Half a pizza plus a quarter plus a quarter = one pizza.
A pizza is 4/4 of a pizza = a pizza sliced into 4 but still together.

The benefit of this approach is you can easily go to 1/8 and 1/16 and do addition and subtraction. Even multiplication and division. Get two pizzas to show 8/4 and 16/8 etc.

And you can eat the whole thing afterwards. Fractions are delicious.
And allegedly, security issues too, including possible SQL injection.

It's not specific to Pakistan: the same problem tends to be seen in many if not all cultures with a strong dowry tradition. If substantial wealth is transferred with a bride, there's a powerful incentive to marry within the family.

(This used to happen in Europe, but during the middle ages the church banned cousin marriages for political reasons: it stopped the nobility consolidating too much power.)
Because knowing both helps realise how it works. Yes it's faster to use short division, but long helps you se the step by step process, giving a better understanding.

Freedom of speech has nothing to do with private platforms that are subject to market effects. Zuckerberg's claims that corporations can and will guarantee free expression is obviously not true.
They are hugely effective.

Even if only a small percentage (e.g. <2%) click on the and, and then a similar small percentage actually buy anything after clicking, you are still making money so long as the cost-per-conversion (i.e. per sale) comes out low enough that you still make a profit. Spending $3-5 to make a sale in say a pair of shoes that retails at $100 with a profit margin of $30-40 is good business.

People are making huge amounts of money/doing huge amounts of business directly as a result of the ads, and that is not just Google and Facebook, but everyone all the way down to little mom and pop businesses.

When you track things down to the level of sales it very often works (not always - depends on products/business models etc), and that is why people are using online ads. AdWords and Facebook ads would have fizzled out years ago if people were not benefiting from advertising their business
So Singapore has Ministry of Truth that decides what's fake or not?

Hmmn, it's awfully familiar, I think I read about that in a book somewhere.
Yeah, when we were taught short and long division I had the same question and it was not until quite late in high school we got the explanation.

I went to school in Sweden where we do teach all this things, but in a strange order.
From my quick google it's arriving at the answer, without the step by step process of calculating each division.

Edit: although if someone else can explain it better I'd really like to know.

From what I have searched,(quickly mind you), it seems to be a mind set.
Isn't this what Sacha Baron Cohen asked for in his speech? That there be state mandated rules on what's fake vs not. I don't think this issue has any good solutions - damned if you do, damned if you don't. The only 'okay' way to solve for this is to crowd-source a variety of opinions on the issue and show what else people are saying about it - not as the ultimate truth, but rather to broaden people's perspective on it that there are different ways to look at the same issue.

I've always wondered how Wikipedia has solved this... Isn't it essentially the same problem?
For me there are two particularly important topics that concern me and that I think are worth a lot of research. The first is the effect of the smartphone (starting with the iPhone, I guess), and the second is easy access to porn.

When it comes to smartphones, I'm just amazed at how much it has changed how people behave not just on a daily basis, but apparently on 5-minute (or so) intervals. That's gotta have some significant consequence.

When it comes to porn, I'm slightly less confident that things have changed significantly, but it still feels like things are different enough to possibly have some kind of large-scale consequences. I mean, I remember a pre-internet and pre-smartphone time where porn was relatively difficult to have access too. The difference is less pronounced than the change to the 'internet-smartphone age', but considering how powerful sexuality is to us, I can't help but wonder how much easy access to porn is affecting us, for better or worse.
Nothing with my Singapore VPN location either.
This is just re-stating the algorithm for the umpteenth time. I can read the algorithm. I just can't intuit why it works or why it has been designed this way.

I mean your very first line has a logarithmic operation that was not mentioned anywhere in your text or your comment! Just pops in there out of nowhere. I guess it's about the number of decimal digits? But why? Why are we doing things in decimal?

A dense ten-line algorithm like this seems far more complicated than other algorithms we try to get school children to memorise.
I've looked at both Wikipedia pages and still can't really understand the difference. Is it anything more than notational? Either way, you're calculating divisors for each component of the problem, and it only seems to matter whether you calculate it on paper or in your head.
I went to elementary school in the 90s and we were taught both long and short.

I think you're right that there is an arbitrariness to this algorithm, and there are other ways of normalizing your data. And you could probably build entire new branches of statistics off of them (like non Euclidean geometry), and they'd probably even be better in some way. But, you'd be speaking a different language from everybody else.

Speaking of language, have you ever thought about how all names and grammatical structures are arbitrary as well? There are parallels.

I don't want to keep going on because it sounds like I'm trolling, but when you tell me 'it tells us what the final normal distribution would look like if you averaged a lot of independent distributions' I just want to say 'why do I care about that? where did that requirement come from?'
I had Olin as a professor while he was still at Georgia Tech.

Below is roughly as I recall from him telling the story. Olin has a colorful sense of humor (see his usenet posts).

The anti-acknowledgements page was originally intended for his doctoral thesis. It was going to contain everyone who discouraged or otherwise hindered his efforts to degree (e.g. parents, girlfriend). His advisor talked him out of it.

Later when he was at the one of MIT's lab he puts in the SCSH manual. The manual gets printed and distributed. He doesn't hear anything. Later he gets called into the head of the lab's office. Olin comes in and sits down. The director takes out the manual and opens it to the acknowledgements section. The first question is "Who has been stealing your work?", the second one is "do you need to go into rehab?". Olin tells him it's a joke. It ended up being a career limiting move for him.
As a former high school math teacher, chances are you did a disservice to them.

Many kids never "get" fractions, but do remember cross multiplication! And so they use it for anything with a fraction. 1/3 + 4/5=? CrossMiltipy! 1/3 x 4/5=? CrossMiltipy! 1/3 - 4/5=? CrossMiltipy! 1/3 ÷ 4/5=? CrossMiltipy! 1/3 + ? = 4/5 ... CrossMiltipy?

Lots of kids complain about math because there is so much to remember. That's a bad sign because there is so little to remember if you understand the concepts as you can always re-discover forgotten tricks.

In similar fashion, as a little kid, I was not allowed Velcro shoes when learning to tie my shoes. After I showed I could master tying them, then I had the option to go back to the easier Velcro option.
I saw my nephew play this. It’s a great idea but I found the implementation lacking.

He got stuck on a level where he had to solve a simple equation, and tried to do it in the “wrong” order. He eliminated an unknown from one side first, and then the system wouldn’t allow him to do the type of operation necessary to complete the other side, maybe because that particular technique hadn’t been taught yet. It would have been a perfectly natural way to solve the equation on a blackboard. I could see they probably wanted him to do the other side first.

My nephew tried the same basic approach 3 times in a row, and then gave up and threw the tablet down and went off to play with Lego or something.
This killed my budget on a display campaign I setup last year and there seems to be no easy way to mass exclude these channels. I even tried setting the content of my ads as not family friendly but still found this didn’t solve the problem for retargeting campaigns.
My spare time is kind of... weird. They were related to concurrency in an actor system, I validated a design and implementation (can’t share much more). I recommend checking Hillel’s blog as suggested, he has excellent examples (and his book is a good starting point for TLA+ and Pluscal as well)
Start with the Normal or Multivariate normal. We start with this because it is the distribution that emerges naturally when we have lots of little errors adding up around a basically consistent effect (see also [0]). So basically any situation where something ought to happen but 101 things could also happen to cause small changes will turn out to be normally distributed. An exceedingly common occurrence + one that almost inevitably turns up when dealing with a practical error prone process.

Now that we have a normal distribution, the mean is an obvious metric to pick because it captures the notion of 'middle' in a useful sense. Then we have proofs that we can characterise the normal with the mean and 1 other parameter (normal normal) or a matrix (multivariate normal). We call that the standard deviation^.

The exact formula wasn't a coincidence. The normal can obviously be characterised by the mean and a statistic from another formula. There were a bunch of experiments tried (eg, using |x| instead of sqrt[x^2]) but it turned out that sqrt[x^2] had some other nice property that minimised some sort of error so they went with it as a standard. I forget what one, might be error of estimating the true parameters from a sample or similar.

We could characterise the the normal as an infinite sum or something quirky, but when people say 'easy to work with' they mean instead of a function or something quirky we can simply pick a number.

Standard Deviation isn't as important when working with non-normal distributions, although I think it still turns out to be useful. But its importance is that it characterises a normal apart from the information captured in the mean. I'm not a mathematician, YMMV, could be wrong, standard disclaimers.

[0] https://en.wikipedia.org/wiki/Central_limit_theorem

^ I'm not going to edit this but it occurs to me that we call it the Variance. Same thing as std. dev in my opinion.

' There is a fairly subtle observation to make - Normal is characterised by mean and std. dev, but the most efficient ( https://en.wikipedia.org/wiki/Efficiency_(statistics) ) unbiased estimator of the std. dev of the population is the adjusted std. dev of the sample. Therefore, accounting for mean, you can't get a more efficient characterisation of the normal than mean & std. dev. Ie, if you picked a formula other than std. dev then the most efficient estimators to characterise it would still be mean and std. dev. Don't recall if there are equally efficient choices but I think that proves there are none better.

That might have been the logic for why std. dev was chosen. Just a guess.
I don't know and welcome any correction to my grammar or spelling.
From elsewhere in this thread I learned that this is actually called "short division"!

I can distinctly remember learning long division as a kid, and I wonder why this isn't immediately taught afterwards as the logical progression
Philosophy is an 'entirely outdated paradigm'..? This is news.
No, standard deviation is special. If you have a large enough amount of independent distributions which gets averaged or added in some way, then the only thing which matters are their standard deviations and average values for what the final distribution looks like.

I'm pretty sure fixing bugs that make money is on the very bottom of the list of priorities....
That was quite an eye opener though when we were taught polynomial division in high school. Not necessarily for how long division works because I already understood that, but because it was an example where short division could not be used.
That's the book 1984 which has a ministry of truth and thought crimes.

They don't, and they are tied into long term exclusivity contracts in many territories.

About a tenth of 1% is totally new content. There's really a couple of documentaries, two features and the Mandalorian. And that's it.

They couldn't launch the service with just that - Apple are struggling a lot and basically giving away their service and they still have more than that.
It was certainly common for a long time in many places, and still is across what's now the muslim world (although I think it long predates Islam). But I'm not sure dowry tradition is quite the right marker, IIRC it's much less common in Hindu tradition (where the pattern was larger caste groups instead).

But it's certainly a way of concentrating power in the family. And presumably, for a very long time, having lots of grandsons of undivided loyalty was important in conflicts with the neighbouring family/tribe... worth the individual fitness cost (and the extra miscarriages etc -- many of these strange illnesses would of course have killed the child).
That isn't a good reason.

We’re subtracting off multiples of 10^N because that’s easy when you write your numbers in base 10. Try subtracting off multiples of 9^N, or multiples of N!, or some other choice, and you’ll see why.
Oh wow! Well, glad I went with Snips then.
Well, that’s like saying “Trump lost the popular vote”. Sure, he did. But that wasn’t the game Trump was playing. Trump was aiming for the electoral college, which is the actual game that matters. In the same way, (Scott Adams claims) Trump is skilled in convincing the people who matter for each issue, Trump is not trying to convince all people in general.
"you are essentially then reverting back to and relying on non-blockchain technologies at that point"

Yes, my point is that's not a choice. It's like making the "choice" to fall down after you free yourself from the shackles of the "conventional crutch system".

Clearly this is not an actual problem with walking without crutches - millions of people handle walking that way all the time!
One of the reasons WWI broke out when it did was that the German General Staff knew that within ten years they would not be able to win a war with the Russian Empire. The USSR was a lot more backward economically than the Russian Empire, as would be expected when you cut yourself off from world trade and investment and kill large portions of your educated classes.

Serfdom was abolished in 1861, so no the USSR did not go from serfdom to the space race.
The problem with this kind of accounting is that it doesn't consider whether the ad was really necessary to make a sale in the first place.

With a lot of brand keyword advertising, companies are paying for people to click an ad when they were already looking for your website anyway. So spending $3 on that customer is not a $27 profit but rather a $3 loss....
Best is a subjective term. When Windows won the desktop it was the best at running MS Office. I don't know enough about hg to say how git is better, but I'm sure there are areas where git excels. From what I've read hg has a better cli, but that alone may not be enough to be the 'best'.
A definition of how the aggregate would look, and explanation on why lesions have predictable results in every brain, as pure annealing based process would produce amorphous results. Why brains are similar in structure?

This model just does not deal well with lesions. After all, a lesion would be even stronger of a change than normal processes or psychedelics, causing the annealing to revert locally while it is healing. We do not observe this "untraining" behavior caused by healed neural lesions as per experiments on quadriplegic rats that get spinal therapy. They need next to no rehabilitation to run again.

Likewise, existence of phantom pain phenomenon is counterevidence - and why it just cannot be simply untrained.

Yes, I literally poked a hole through this idea. If it actually ever produces working results, then it should be able to fix phantom pain.

Likewise, single seizures would cause permanent changes in personality or skill as aftereffects, which is not observed.
Whereas repeated ones do, but still not exactly with permanent effects.
How does this model explain the difference? The applied "energy" is the same...
However epileptics rarely show similar effects, even if they also suffer Grand Mal seizures. Why the difference?

Why do mood disorders show up most often in adolescence and say not later? How does this model explain age related dementia? Why only certain anesthetics cause mental problems? (Or sometimes cure, e.g. ketamine.) Etc.

The model perhaps works partially in a normally functioning brain, but does not help us understand at all how memory is formed or why is it located mostly in hippocampus. Why cerebellum handles balance and movement, why there is another cortical movement handling?
"An attractor forms" begs the question of "why" or "why in this form", which this theory cannot answer. (Especially why these structures are mostly already formed in utero, but still need additional training.)

Whereas developmental neuroscience based on proper hormonal basis can. (Up to a point, it's quite new.)

The whole thing is a logical (as in high level) explanation based on no biological basis. It lacks the complete causation chain for how psychedelics operate and why every one of them produces different results.
Most importantly, an underlying chemical based model would produce identical results as the neurons themselves change permanently in response. (See: neuronal memory allocation mechanisms.) We just do not understand all the neurochemistry related to specific chemicals. Likewise how psychedelics and induced seizures are related. They are, but not entirely and any useful model would explain the difference rather than cover it up.

Neuroplasticity is being studied, a simplistic model of "annealing" is not helping in understanding - whereas results relating to say biology of cell given specific inputs are. (E.g. LTP and its relation to CREB and thus other neurochemistry. Synaptogenesis and axonal chemotaxis. More... That get activated during normal and abnormal operation.)
Economics of stocks is a good example, when you put a lot of stocks in one portfolio you can calculate its risk (standard deviation) and returns (average value), and see how much each piece of stock contributed to that. This is because the results of many variables looks like a normal distribution with the combined average and standard deviation. Now it gets a bit more complicated in the real world since stocks are not independent from each other, but it shouldn't be hard to understand why knowing the standard deviation of something is useful.

The last two actually imply what they are about, but the .org could be anything.

Trust and faith in the service associated with a domain needs to be built with standard channels like word of mouth, advertising, good business practices, etc.
