Car companies haven't had a major impact on American culture and politics? Have you been to an American city or suburb?
A general formula is:

d1 = n % 10

d2 = n/10 % 10

...

dk = n/10^(k-1) % 10

There are a number of implementations possible, iterative is probably more economical. Another way that avoids integer division (if you just want +/-/* ) is doing all your arithmetic in BCD (binary coded decimal), using 4 bits per digit.

I think those kinds of exercises are useful because there is some confusion around arithmetic. Sometimes there's confusion between what are numbers, and what are number encodings or digits (which themselves represent individual numbers). I found myself confusing (or simply not having the concept of differentiating) the digits of a number and a number itself. Say '14' to me was uniquely associated to those two digits. When you learn binary arithmetic, you start generalizing and see it could be written '1110' as well. The number 18 is a concept independent of its representation. So you can talk about the digits of a number: the digits represent individual numbers themselves, but they are taken together to represent another number. In my example, I had 'dk' and 'n', where n is a number that will usually be represented in binary form, but that is irrelevant, and 'dk' are their digits, as numbers, also usually represented in some binary form (again might or might not be relevant). You even consider simpler encodings such as unary (e.g. as used in tally marks or finger counting), those of course have lower efficiency (O(logn) vs O(n)). They're all just representations of this abstract concept that are numbers (with which we can do mathematics and arithmetic operations).

I think it's illuminating to distinguish between digital properties (properties specific to a digital representation), and properties of numbers. For example, 4 in base 3 is 11, which violates the property that even numbers are those whose last digit is even (only true for even bases). Divisibility by two is a numerical property, last even digit (implying evenness) is a digital property.

Numbers are so simple conceptually, it's their digital representation (and digital arithmetic) that's a bit more complicated.

It seems that this is aimed exclusively at operators that already have the infrastructure to issue SIM cards et al, and communities that are barred from deploying their own infrastructure but willing to pay for it. A weird use case but clearly aimed at US and AU markets I'd guess.

You need a community that will want to front the cost of laying fiber, and then instead of distributing or starting a small ISP/coop will give that new termination to a telecom giant who will plug this device into their existing billing network to provision their new subscribers with access under the existing plans costs.

Lol, it's not because police are engaging in shoot-outs with the cartel. It's because we have a judicial system that will not stop going after you, and that is all done non-violently.

I would say that calling libertarianism an extremist ideology is a gross misunderstanding of it. My guess is everything you think you know about libertarianism, was what you were told by somebody who hates it.

Full-on anarchism, or anarcho-capitalism, ok, that's a hard sell.

Libertarianism? It's basically "never initiate aggression" and "live and let live". That's about it. I don't know what's extreme about that.

> Anaconda does, which makes it possible to import those libraries in projects without explicitly listing them as dependencies.

I think your main problems are very naive users of conda. If you bring years of experience using pip, but use conda thoughtlessly, I can see your point.

If you don't want packages included, just use miniconda and install the ones you like. You could just create a new empty environment: `conda create -n py36 python=3.6`

Either way, it's completely reproducible.

When not using wheels, pip can be pulling in various versions of dependencies. Conda makes it easy to see all of them before they are dumped into your environment.

> Anaconda overwrites the system python by messing with the user's $PATH regardless

I understand what you are saying now. It's covering up system python in the PATH, but it isn't overwritten. Using `type python` (or which python will be correct 99% of the time).

> The issue with conda is it's different package repos, not the ability to lock package versions.

I thought this was your major argument. "Collaboration is difficult" when in fact it is much, much easier. You are getting the same binary everytime without slight differences in how it ends up compiled on the user's system.
No, but I think that's more comparable to e.g. the Civil Rights Act of 1964 (only the opposite). Even then, it's outside the scope of these software projects, in my view.
- methane is a very potent greenhouse gas. What's the effect of methane in the stratosphere?

- there are some results suggesting soot emissions in the stratosphere could be a problem if space launches increase a lot. Methane burns a lot cleaner than kerosene, but afaiu some soot is still formed.

Now all things considered, given nobody seems interested in a pure hydrolox lower stage due to the poor impulse density, methalox certainly looks better than alternatives.
> But we have evidence about respiratory viruses and masks, and it all says they don't work.

What? Medical personnel regularly utilize surgical masks against respiratory viruses spread by droplets successfully.

They're less useful against aerosolized stuff like measles, but SARS-CoV-2 is primarily spread via droplet.
Yes, you can re-write it without using cat, but many people (including me) think it's clearer to read from left-to-right. Plus the mixing of sending the file through stdin and then using a pipe always makes my brain pause.

I just personally find that using cat as the first part of the pipeline makes everything easier.

Plus, if you're going to argue against useless use of cat, there's also no reason to send the file in through stdin. jq can read the file directly.
The input redirection pipe is not necessary either:

>There are no "close-call mistakes" in the situations which have caused outrage

I agree with you on that! As I said, "the clear cut ones pull at our heartstrings because they are so egregious."

The problem as I see it is that it's hard to tailor a bright-line policy that creates increased personal liability for police for their clear abuses of power and brutality, that doesn't also create increased personal liability for their close-call, reasonable mistakes. Some of the "5 demands" I have been seeing seem like reasonable starts [0]; none that I have seen focus on increased personal liability.

>If changing that causes some people to "avoid taking a job", good.

I would guess that you and I have drastically different estimations of how large an exodus from policing the wrong kind of policy change could cause. We need police reform, but we also need police.[1]

This reminds me of the James Damore incident. They asked for people's honest thoughts, and that's what they got. What they actually wanted was for their employees to shut up and toe the line.

I always wonder what the thought process is behind this sort of thing. Do executives live in such a bubble that they honestly believe all their employees agree with them? Or do they simply expect them to be too intimidated to speak their minds?

I suppose the answer is clearly the latter, since their solution is to de-anonymize the meetings.

Authority isn't the point and is irrelevant when it comes to simply observing the pattern. The point is a pattern where violence can often escalate with a more violent response. Recognizing that pattern can help in short-circuiting it.

However, if you do want to get into "authority", just look at the many officers around the country in the last few week that have been suspended or fired for unjustified use of force against protesters after being caught on camera. They had no authority for that use of force. Authority has limits, and those limits do not prevent the escalating pattern of violent behavior. But again, that isn't the point: Authority is irrelevant when speaking of observed behavioral patterns like this. The pattern exists, authority doesn't prevent that, and a failure to recognize that pattern or simply brush it aside by saying, "well the police had authority to do it" is not helpful, not if you're interested in actually solving the problem

Let me put it into technical terms if that helps you understand it better: Imagine a buffer overflow results in a escalated permissions for code execution. Here I am saying "This is what's happening." While there you are saying, "But that code had no authority to execute like that!" It is both true, and irrelevant. It is happening, and recognizing that problem helps in moving towards a solution.

so my original claim was that:

> i can extrapolate even further and say that everything is a state machine. humans are a state machine, plants are a state machine, reality itself is a state machine.
we don’t see it like this because of the sheer complexity, but in the end we are a continuous computation that occurs at every moment in time.

Godel incompleteness applies for math, logic, etc but you need to understand that math is human construct. formulas and numbers don't exist in a void. they need a substrate like a human mind or a computer.

Also by state machine i mean a system is basically a current state + state transitions. I was not using state machine as a way of modeling and solving a problem. That's a narrow definition of a state machine only applicable within a certain domain.

so everything in reality can be seen as a state machine

also as an orthogonal side note to the the halting problem: in theory you may conceive of systems and/or programs that will never halt but remember they are theoretical. Eventually, entropy gets to us all so for anything, even ideas of algorithms that may never halt, is temporary and are guaranteed that given enough time they will halt.

I am all for private businesses' right to censor their platforms as they please. But let's consider why they do so. Amazon and others aren't banning "covid dissidents" because they are worried about people's health nor is it because of some evil conspiracy. The reason is simple and obvious: because they've determined it to be the best course of action PR-wise. Or in other words, it's because what the public wants.

And that is where it stars to rub me very, very wrong way. Just think about it. Not only the average Joe knows exactly how this totally novel global problem with a shit ton of unknown variables should be handled (that's par the course). But he's so certain of his knowledge that he wants anyone trying to voice a different opinion to get the treatment that was previously reserved only for obvious dangerous crazies like the nazis. To me this is the empirical proof that the slippery slope does exist, unfolding before our eyes.

There have been reports on this site, of severe healthcare provider (as in HIPAA protected data) privacy violations, that occurred via data broker intermediaries through popular social media platforms. You know, getting a $60 FedEx package consisting of baby formula, during the month that the baby you miscarried should have been born, that almost cost you your life too.

The amount of bad medical data, erroneous medical data, and just medical errors in the US is actually unbelievably astonishing.

Finding correlations in datasets (even the most perfect dataset!) for use in healthcare is a profoundly unethical social experiment, both among the population and the individual.

We all know that the field of software engineering has faced scandal after scandal when it comes to ethics. The list of examples is practically endless now, and this is one of the most dangerous examples by far.

That's not what I remember. Wikipedia backs up that recollection as well [0], marking systemd's initial release in 2010. Docker's initial release is listed as 2013 [1]. Maybe that was true of the dotCloud internal releases, and certainly, not all of the EL and other Linux distros had not adopted systemd during 2010 - 2013. Certainly after 2014 or 2015, systemd had spread to the major Linux distros so Docker could have chosen to take a systemd-based approach at that point.

Why are web tools/services so expensive?
It seems like web-based software programs have gotten so expensive. This includes things like diagnostics, uptime monitoring, mobile phone emulators, and other SAAS products etc. Often there is a free trial but it is very lacking and in order for it to be useful, they require payment, but it is so expensive. $100/month for one month or $40/month if you sign up for 400 months or some lame gimmick like that. Are web service apps that costly to develop that it costs 4-10x as much as a Netflix subscription?

I understand where you’re coming from but it still seems dangerous. There will come a point when we will not be allowed to discuss inconvenient facts or debate controversial and sensitive topics (some would argue we are already there), and the definition of what fits into that bucket will shift. A vocal enough contingent just has to declare something a “bad faith idea” and you’re done.

What’s worse is the new trend of digging up something you said/did that was of little societal impact at the time, but is now unforgivably offensive, and society punishing you retroactively under the new rules.

that is the strangest re-telling of the Flint water-quality story that i've ever heard.

Nearly everything indicates that the steps in Flint were cost-saving measures that the citizens either 1) didn't know about, 2) were told that there wouldn't be problems, and 3) were promised health concerns wouldn't be a factor.

Where exactly does this 'wealthy town that's overly confident" narrative fit? That hasn't been my perception at all with Flint.

I reason the difference is mostly when metaprogramming can happen. In Java, redefining or adding code is very explicit, it can't just happen whenever. Same with C#. And there are lots of rules. A class can't modify itself, and there's limits to what changes you can make. And to make changes you must have control over the "classloader" that loaded that code.

JS on the other hand can do most of what ruby does, to my knowledge. Objects are key value pairs so you're free to mess with them in virtually any way you please. You can also mess with the inheritance by altering JS prototype chains.

I don't think metaprogramming itself has much to do with the speed of Ruby, with my admittedly limited knowledge of this stuff
