> About 5% of customers will not hesitate to be abusive, pay extremely late or exploit the fact that you're small. Learn what they feel like in the sales process. The first time you'll be convinced it's you, and blow at least a month. Learn to fire them during the sales process or insulate yourself with much worse terms for them and stronger for you (paid up front, higher rate, easy out for you). Dealing with abusive customers is one of the hardest "didn't expect that" things I've experienced. Otherwise, enjoy.

Some of the best advice I've seen in a while.

In my situation, most clients/users are amazing, understanding, and appreciate the work we're doing.

Between 5% and 10% are insane. In my very small part of the market, I've learned that most horrible clients will be either very small (1-2 employee businesses or family operations) or enterprise level with sloppy internal policies. I try to catch on early and tweak the terms to: a) discourage them from using us b) insulate us from their hellish behavior.

Google's search results have never really been that great, to be honest, but their relative quality has drifted up and down over the years. For the quick-and-dirty searches that most people use Google for (including me) it's "good enough". But if you try to use it for a truly detailed search, and even if you pay close attention to what often gets returned for the average Q&D search, the results can be surprisingly lacking.

Funny story: Some years back I happened to mention the above casually in an online discussion concerning some unrelated topic. One of the participants in that discussion then challenged me to provide details, which I did. I thought that would be the end of it, but instead the other guy came back at me with what can only be described as "nasty" responses to my critique. This got me curious, so I dug into his posting history and it turned out that he actually worked for Google. When I brought this to everyone's attention he then proceeded to start deleting his posts, both the current ones and the ones in his history, which I thought was funny.

Now, under the circumstances he could have come back with suggestions on how maybe to improve my searches, or explaining why I might sometimes be seeing incomplete and/or inconsistent results, or what have you. But that's not what happened. Instead he treated me as if I were some kind of saboteur or something, one who was attempting to besmirch the good name of Google.

It's not about malice. It's well known that public statements by corporate officers and other key people can move the market so their statements tend to be scrutinized by all sides, including regulators. Another problem is it's often difficult to prove/disprove if a statement is an honest mistake or a misrepresentation (or even outright lie.) That's why it's so rare for company officials to go 'off script' when making public statements... pretty much everything they say is vetted by legal, PR and pretty much any impacted group in the company to ensure they don't step in it. Walking back / clarifying statements in his role can be much more costly than just keeping silent until you have the facts right.
Germany's population growth is already negative, people still want to live in cities, hence they grow while rural areas decline.
Yes, you're absolutely right! And actually, much more recently we have been been trying to steer our work towards addressing point (2) you raise above.

It became apparent to us, as you say, that most people will find this stuff simply by asking google specific questions e.g. "how many people are there in the world?". And a lot of our existing content will not appear in Google or Siri as the answer, despite us having it in longer articles on the site.

So we've been very recently trying to answer much more explicit questions that people would ask (although we should have been doing this much earlier), and are thinking of reformatting a lot of our existing content in this way too.

Thanks so much for sharing your thoughts - it's really helpful perspective for us.

Since these comments imply that research firms already mine this, I think there's a hilarious opportunity for rank-and-file engineers at these tech companies to vend fake features/experiments (in which nobody receives the treatment), and watch hedge funds overstep then get the rug pulled out on them. At the least, the practice would cheapen the practice of data mining of the experiment names without having to implement any substantial fix.

> It's a bad interview question IMO because it's a puzzle question.

You asserted this in your first message. The point of my reply is to show that it's not a "puzzle", and that a reasonable line of thinking and reasoning can guide you through the problem to an answer. The naïve answer one might get here is fairly "undisciplined", in that there's no rigor in language theory, no deep discussion, but the question is still answerable.

> the magic trick to use a stack

My suggested line of reasoning does not use a stack, beyond function calling. If using the actual stack is a "magic trick", again, I think we have removed so much material from consideration as to not be able to ask anything of use.

Again, if we simply dismiss any line of reasoning that a candidate might not see as a "puzzle", then every question is a puzzle, and nothing can be asked in an interview. Simply repeating your thesis that it's a puzzle does not advance this discussion: do you not think the line of reasoning I laid out is reasonably obtainable in an interview? And if not (since I think it's a fairly minimal one), then what types/sorts of questions should an interview ask, since it would seem like I'm left with only things that are dead obvious (b/c if it wasn't, it's now a magic trick puzzle), and that leaves me with nothing to screen candidates with.

As an interviewer, I want to see you struggle with something you might not fully understand, and I want to know your reasoning and thinking as you go along with it. The real job is not going to come with a manual, after all.
Why do governments go this direction when it causes so many problems?

In a market economy, which includes both housing construction and home rentals, price is the signal by which demand is measured. Rent control either eliminates or severely distorts that signal.

I’m going to predict that:1) fewer new homes will be constructed and 2) rents will sky rocket where it’s possible (tenant turnover).

In this case I don't think what the article says is exactly right. Naively, tensors are just n-dimensional arrays, which TensorFlow supports. The paper linked in the article appears more to be talking about how derivatives of tensors are represented in TensorFlow. The difference doesn't seem to matter unless you are taking higher-order derivatives. This makes sense, since TensorFlow is focused on first-order derivatives needed for gradient descent, but traditional machine learning algorithms also rely on second-order derivatives to make use of more powerful optimization algorithms based on Newton's method. I'm not sure exactly where the difference comes from, but it comes from a convenient notation for tensors used in physics, known as Einstein notation (Einstein invented this notation to make his life easier when deriving general relativity). In this notation, tensors are represented by a single scalar variable. For example, matrix multiplication y = A x is expressed as

y_i = A_ij x_j.

If I understand correctly, the paper points out that an algorithm for computing derivatives based on this notation is faster for taking higher-order derivatives compared to using TensorFlow.

Mathematically, tensors are more complicated objects. Basically, they are what you get when you take higher-order derivatives of a function. In particular, the first-order derivative of a function f: R^n -> R^m at a point x \in R^n is the best linear function A_x \in R^{m X n} that approximates the original function, i.e.,

f(x + dx) ~= f(x) + A_x dx.

A linear function is represented by a matrix, so a first-order derivative is a matrix. If I take the second-order derivative, I get a more complicated object B_x, which represents the quadratic term in the Taylor expansion:

f(x + dx) ~= f(x) + A_x dx + B_x(dx, dx)

where B_x(a, b) is a linear function (or more precisely, a "multilinear" function) of two vectors a, b (which are the same in the above formula). That is, whereas A_x is a (linear) function R^n -> R^m, B_x is a (multilinear) function R^n X R^n -> R^m. This mathematical object B_x is an example of a tensor. In R^n and R^m, tensors are pretty boring, but they become more interesting when dealing with functions on manifolds.
I actually wrote a program which showed behavior that appeared to be "social" after predictors were added to the simulation.

The postulation being organisms have a pressure (from predators) to form groups and eventually societies. Essentially, they'd either survive by evolving to be social, evolve defense mechanisms or die out. Social evolution may actually be the shortest path for non-aggressive species because they simply have to bare one another, as opposed to evolve long claws or something.

Very hard to prove, but our model showed given the options social interactions appeared more likely with basic reward circuitry.

I could see from an ideological perspective Twitter's entire mission being to delete the middleman and the moderating PR managers and public statement lawyer sanitation of everything public figures ever say, which was the only way laypeople heard anything a famous person ever said (that or tabloid gossip "overheard"s). I can respect that ideology, but it of course comes with its own set of problems.

Personally I'm amused and ok with famous people facing the consequences of voicing their opinions, and also them getting roasted by normal civilians in public thanks to twitter.

That depends on whether you consider a misphrasing to be "information".

That's unfortunate, because inflation is a social policy, that, by design steals from the poor to give to the government, which generally gives to the politically connected (read: wealthy). Even when it gives to the poor, it's filtered through the wealthy, I once was on a volunteer route and found solyndra panels on top of section 9 housing, which undoubtedly increased the cost-plus of the construction project.

Why do I say it steals by design from the poor? Don't take my word for it, take Paul Krugman's:

https://krugman.blogs.nytimes.com/2010/02/13/the-case-for-hi...

> It goes like this: even in the long run, it’s really, really hard to cut nominal wages. Yet when you have very low inflation, getting relative wages right would require that a significant number of workers take wage cuts. So having a somewhat higher inflation rate would lead to lower unemployment, not just temporarily, but on a sustained basis.

Let me reframe this in cruder terms: "The proles are dumb and management is too lazy to negotiate correctly so it's better for society if we put workers on a rolling treadmill"

No way that can go wrong.

As for correcting income inequality by fiddling with upper tax rates or providing social services. They won't work. Those effects are linear. The effects of inflation are compounding.

Would you be able to explain some of these questions further?

It seems self-evident to me that there are only a few options:

- Human brains aren't conscious (which we humans tend to dispute)

- Human brains are conscious and have experiences as an inherent byproduct of accepting and processing sensory input which includes input on their own internal states (ie. there is no 'hard problem')

- Human brains are conscious through some other, as-yet-undescribed mechanism which operates in parallel with the systems described in the last option (a 'strange loop' separate from the 'mundane loop' of our normal feedback system)

- Human brains aren't inherently conscious and consciousness is imbued into them via some supernatural phenomenon (which feels like abdication to me - 'a wizard did it' is never a satisfying answer.)

I'm only an armchair philosopher so I'm well aware there may be some widely accepted conclusions on this stuff that I've just missed so far.

Farm animals don't have long lives. It's likely possible to continuously escalate the dose such that they'd never have to suffer. If not, wireheading can bypass problems with tolerance.

It looks like our real disagreement is "perfect is the enemy of good". If you don't want animals to be killed for food, then animal suffering is actually a good thing, because animal suffering helps convince people not to farm them. I'm working on the assumption that humans are going to continue killing animals like they've always done, and therefore it's better to reduce suffering with the most effective methods available. If animals are going to be farmed anyway, I'd rather they have access to an unlimited supply of recreational drugs (or equivalent brain modification technology). Animals don't care about the top of Maslow's hierarchy of needs.

Why is using a test set for evaluation a deadly sin?

As I understand it, you fit() with training, then do parameter tuning with validation and the best parameter tuned model is used on test.

Now I'm still a little confused as to why we don't just fit() then do hyperparameter tuning with the test set (best-tuned model wins, no need for test). Why would calling predict() on a model cause it to update its weights and overfit?

I am really excited about things like operator<=> which with a compare like interface will allow the creation of all the comparison operators. This is a lot of boilerplate that won't be needed any longer. Also, it has sane defaults so you can get them without doing anything in many cases.

Also, Non-Type Class Template Arguments. Finally strings and other things in template arguments. This will allow for some really neat things like CTRE https://compile-time.re which generates optimizes regex at compile time instead of constructing them at runtime. Also allowing the optimizer to do its magic( match<"regex here>">( "Some string" ) is the syntax). Using the type system to describe parsers will allow for really clean code for such a common task.

It's a deadly sin considering that many (most?) researchers do not treat it as a test set, but as a "validation set #2". Basically, you tune your hyperparameters (up to the random seed!) to fare better on the test set. So, as shown in the cited paper, the results are not generalization results anymore.

I think the idea is that "calling predict and tuning on a model with the test set" is the "overfitting". It's not actual overfitting like we know in ML; it's as if the researcher is performing "descent" to get the best hyper-parameters. Problem is, if we use the test set to find these hyper-parameters, we'll have no idea how well it does in the real-world/in general. We'd need another set to figure that out - and we're back where we started.
