This is a good lesson on perspectives. I've had a few encounters that have brought it home to me. Here's a list of experiences...

- A hated executive team that wreaked absolute havoc in the lives of thousands of people for the sake of a thought experiment which failed, which had failed elsewhere, and could have been implemented in a sensitive and non damaging way anyway. I met a member of this cabal socially years later, and because of personal connections and the need for social smoothness (I have a family and a mortgage so I can't just flounce about) I was compelled to play nice and chat. Over the course of the conversation I realised that this team believed that they had been on a mission to save the company and that they had succeeded, that they were loved by the people they had maimed (many of whom would have had to be restrained had they been in earshot of the conversation) and that they had been removed and denied the credit by "dark forces"!

- Employees who when asked opinions about strategic decisions articulate positions that are the polar opposite of the agreed corporate position and sound lunatic (initially) but on reflection, well it turns out that these positions are absolutely as consistent and coherent as the product of 100 slide decks.

- Retired colleagues who ask about some initiative or team that is now entirely forgotten in the corporate body, but when it is mentioned I suddenly realise that it was hugely important and significant, but like Stalin's victims, it's been airbrushed out of history!

- Execs who's focus is on trivial aspects of the business and / or who openly articulate conspiracy theories about grass root business units "I bet they're itching to..."

From Wilson's point of view the pressures and outcomes that he observes are likely significantly resolved and mitigated by the IPO that they did. He probably reflects over a view that moved from immanent displacement and forced illiquidity (due to investors refusing to wave conditions and covenants in agreements that would then mean that no new cash could be generated) to a sunlit upland of board freedom (now threatened by asset strippers). This is not a perspective shared by the founders or employees or even customers, but Wilson almost certainly hasn't spent the considerable cognition required to get that idea.

And this is the problem, even relatively little companies like Etsy are staggeringly complex, there's just too much to consider for a human to fit the required views in. To get the view you have to constantly review and consider and check.. leaving no time to do, and do is needed!

There's been studies to this, for example [1]

"Dando's previous research had already found that when you chemically block people's ability to taste sweet flavors, it makes them crave more sugar and seek out higher-calorie treats. Based on his collective research, we now know that drinking a caffeinated cup of coffee, which has the same blocking effect, makes people want cookies or cake more than they otherwise would."

Caffeine seems to blocks the adenosine receptors, which makes us feel less sleepy, but these same receptors also play a part in helping us taste sweet flavors. While doing this, it pushes us to find more sweet, sugary tastes. This might be a part of why when drinking coffee especially, which is also pungent and bitter in taste, opposed to sweet, might drive us toward these sugary treats.

Also I feel coffee depletes our energy levels very fast, making us feel more tired when the effect comes down, making hte body want to replenish those energies quickly, and high in sugar ingredients do that fast, with a price though.

It's interesting why tea and mate for example don't have this effect so clearly, maybe it has to do with the bitternes of coffee and the way it is roasted, not sure.

Yes. That is how it happens in urban India. Even for nursery admissions schools interview both the kid and parents to see if they have potential.

Okay then he should do something else.
The lesson is that extremes and monocultures are generally failures. Moderate and diverse economies are probably better fit to long term success; in the short run ideology can generate massive benefits - like war communism did. I would argue that many of the economies of the developed world have swung far to far toward plutocracy and injustice.
Avira Antivirus Pro 2018 Crack Plus Registration Key Free Download
I'm saying, I currently pay for a quality of service, e.g. 30 Mbps up/down, certain monthly bandwidth, maybe 'boost' during non-peak, whatever. I also use a VPN when I work from home, I have to. One day I notice my VPN speed has dropped, the VPN is fine, but I'm not getting the level of service I'm paying for. A call to complain would fix it, either with them apologizing or them saying "oh, you have to pay $xx/mo to get on our business tier with no throttling."

Note, Comcast actually does something like this already. If you get on their gigabit plan, their dumb monthly cap of 1 TB still applies, but you can pay more to remove that cap and go back to the unlimited it used to be.

No, not really. London doesn't have a high density of high quality independent cafes/delis. The majority are worse than Pret.
L-Theanine is great when combining with coffee, but at least for me when I've experiment with this combination, if doing it routinely, it really can start to deplete maybe the serotonin levels or something in my brain, because I start to feel more dull in a way, it's hard to describe, it's kinda like this slight fuzziness.

Just for more info, I've been experimenting with 200 mg of L-theanine combined with one cup of coffee. Not something I would take in long periods, but definitely useful for those stints where you just have to get something done and need the stimulants.

L-theanine is good also for relaxation alone, and calming the nerves down, I sometimes take it by itself if I feel too anxious also.

> But does that not invalidate the article's entire thesis? Maybe if they listed the representatives who voted against the bill, and showed that there is a significant difference in contributions, it would support their thesis. But they don't do that.

A significant difference would not so much support their thesis as fail to support the negation of their thesis.

What articles such as this almost never consider is that donors might choose which politicians to donate to and how much to donate based on the publicly stated positions of the politician and the politician's party, that politician's past votes, and the general political philosophy of the politician and party.

If we banned all political donations, and put a limit on political spending by the candidates or on behalf of the candidates, switching to funding campaigns entirely out of public money, a bill like this would STILL be largely supported by Republicans and largely opposed by Democrats because of their philosophical differences.
Ah, yes.

Well, anyways I value code simplicity more than anything.

Maybe CPUs will learn to do cache prefetch for link oriented languages: if a "load and dereference" pattern is detected, CPU could prefetch the data referenced by pointers it has in registers or recently fetched cache line.

BTW, linked list elements are not necessary located far away from each other, if we allocated them one after another chance are they are near each other in memory.

Okay, but I'm still not following the initial comment on "they won't throttle", when you just described a situation in which they throttle?

What I'm missing is how the initial comment relates to the first, specifically they won't throttle or make any QOS changes because too many people use it. We've seen that Comcast in particular is more than happy to throttle services just because they can or want to, and in the case of Netflix, consumers didn't even have an option to pay more to make it work properly; Netflix just would be terrible for them no matter what.

What I'm saying was a response to the idea that people can somehow just use a VPN to circumvent any restrictions, which makes no sense to me. Usage reports will clearly show a high level of traffic going over VPN, and the response will just be to make this part of a new tier of service as well; to recoup the value lost by people bypassing tier/package service with a VPN, the price will be adjusted accordingly.

So I'm sorry, I guess I'm just being dense, but I'm not sure exactly why VPN services wouldn't be affected if VPNs became a means of circumventing the intended Tiering/Package offers.
This is a valid criticism from a practitioner point of view. From someone doing research in algorithms and data structures or someone just curious about it at an intellectual level, there is a different criticism:

All this focus on algorithms for the sake of interview-preparation gives the false impression that the field is a closed body of work. In reality it is an active and lively field of research with many (even most) basic questions not yet understood.

Someone could go through these 500 questions and for (almost) all of them formulate variants/extensions that would be open research questions. So instead of memorizing them, ask for each: Is this the best possible solution? Can I prove it? What if I restrict what the algorithm can do? What if I give the algorithm extra powers? What if the data comes online? What if the input is noisy? What if I want to optimize space usage instead of time? Is there a trade-off between the two? Etc. etc.

And related to the parent question: does the problem model a real practical problem? Why not? Can the model be changed to be more realistic?

All that being said, at a first look, the list seems like a quite nice collection of techniques.
Whatever happened to the BananaBread Engine demo that was supposed to show off WebRTC based game networking? Now the only public demo is single player. A twitch FPS shooter pushes networking more than a social chat room.

Seems WebRTC wasn't mature enough at the time. Would be a good showcase if it was brought back.
> Next cool possibility: use a Rust-like LISP

Why do you want a Rust with Lisp syntax? I don't see the benefits of such a "Lisp" if you take the core benefits of metaprogramming at runtime away which depends on the equality of code and data.

Safe software can also be written in other languages than Rust. Ada is still industry standard of safe programming today. Even Lisp can be used to write safe software since Lisp's memory management takes care of possible pointer problems.

Rust shines in the field where Mozilla developed it for -- safe Internet browsers. However, safe Internet browsers could also be written in Ada and Lisp. The Lisp version would just not be as performant as Ada's and Rust's.
I find that green tea is often more useful than coffee if you just want a mild push, since it’s basically low dose caffeine. It also has L-theanine which is a mild anxiolitic and can counter caffeine’s anxiogenic effect. Some also find that taking an L-theanine supplement (OTC) along with coffee can also counter most of caffeine’s anxiogenic effect while keeping the wakefulness and focus.

This is a junk article in my opinion. I ran the global collaboration open source environment for sony Playstation last decade and was heavily involved with 'enterprise 2.0' in the web 2.0 era.

The idea that 'collaboration' is cramming everyone into an open plan office is idiotic and has more to do with corporate cost saving than any coherent attempt at getting people to work better together.

Remote/home working collaboration is the norm now, yet the old command and control hierarchies, because they generally don't work that way, still have little visibility or understanding of how people actually work together.
Right, though I'm not sure what this has to do with our discussion?

I think your argument is a perfect summary of the conventional progressive view. I'm progressive and very sympathetic to the argument you make.

But I think there's a lot more going on in politics than this neat narrative spells out.

I pulled out the Trump thing, because it's a great example of a person who spent a lot less than his opponents but won anyway.

https://www.vox.com/2016/2/9/10941690/campaign-finance-left (which was written prior to Trump) has a lot more details on this.

To pull a quote: research on lobbying suggests that lobbyists are not the omnipotent power brokers that voters sometimes imagine them to be. Further, it suggests that insofar as they matter, they matter for reasons that are hard to regulate away.

I think campaign finance is important, but more than that I want to see progressive candidates win.

I don't think the nihilist argument that "politics is broken" is correct. Nor do I think there is anything which implies an inherent conflict of interest in politicians. A pro-NRA candidate will be supported by the NRA, and if they win they will listen to people they already know. The same with a pro-environmental issues candidate.

This isn't simply being beholden to special interests - there is a strong interdependence between the group and the candidate and it runs both ways.

Most wealthy people are moderately intelligent.

Really intelligent people often are poor... Once you get rich, you get lazy because your money starts working for you and people around you constantly feed you with false confidence and optimism and this makes you even lazier.

The smartest people I know are all poor in terms of wealth but sometimes they have high incomes.

Intelligence is not a single thing because there are many different types and almost no one is good at all of them.

There is emotional intelligence, reasoning ability, critical thinking, communication ability, spatial reasoning skills, mathematical ability, subconscious reasoning, etc...
The second part of this confused me as well, because the algorithm only detects the existence of the cycle, not its length. However, once you know a node in the cycle (which this algorithm will provide), you simply go around the cycle once more and you have the length.
I agree. An an author of several command line tools I would never document it's usage in the way the classical man pages are structured. They are in times of dire need, frankly, unhelpful.

I ALWAYS have to Google it, since the man page gave me nothing.

I may have just misinterpreted your statement, "So go ahead and use a VPN, but it won't matter when you're throttled to 50 kb/s" to mean they would throttle all VPNs no matter what, which is what I was saying wouldn't happen because in the worst case you have to pay extra for unthrottled VPN use but it's still available. It's not a great outcome, nobody likes having to pay for things they used to get for free, but it's not an existential threat to the internet. If you didn't mean that, probably my fault for not reading carefully enough this late.
The only thing that can be deduced from this observation is that these traditions are not deadly in the short term. After all, smoking is a tradition in some cultures, even though we are sufficiently certain smoking is harmful.

In the original comment of mine that you replied to, I suggested how to make the methodology even more scientific with a double-blind study. As far as anecodtal evidence this is going to be the best that you can do. I personally find it convincing. These are reasonable people testing things as scientifically as they can.
Some of these answers are not great, and wouldn't stand up to interview scrutiny. For example, the "Check if linked list is palindrome or not" problem says copying the list would be too expensive. The proposed answer (recursion) some how avoids this.

The solution is technically right, but it's making a copy of the list too. The intuition is wrong.

Creativity seems unimpeded when the one being creative is at the very top of the hierarchy. It doesn't really work for anyone else unless they have a direct contribution and connection to the dictator though.

Any requirement that new stuff be reviewed by committee (e.g. a board of directors) will tend to destroy anything truly innovative.

Why? Because the creative people can see much further than the (much less involved) committee. They seem like crazy people talking about a world that doesn't (yet) exist.

Elon Musk is doing so well because he has such an iron grip over his companies. If he ever becomes subject to real oversight he'll fail as hard as Jobs did under Scully.

It’s more like acquiring knowledge of the mechanics of a safe dial lock: if the mechanism exposes a safe interface, it doesn’t matter. Only if there’s a flaw in the inner workings of the lock, that an attacker can exploit from the outside, does it pose a problem.
> Meanwhile, in 1869 an American medical publication called medicine “the most despised of all the professions” and advised undergraduates: “Don’t study medicine: anyone can be a doctor.” In 1913 the American Medical Association estimated that no more than 10% of physicians were able to earn a comfortable living.

1869... 1913... These years were not high-points in the development of medicine. Bloodletting was a standard treatment until at least 1850. The first wonder-drug, Asprin, was over-used in 1913.
We seem way too focused on whether coffee is good or bad for our health.

You are right that a lot of Lisps consider themselves more procedural than functional and I was extrapolating Clojure there. (In my defense, the Scheme community is also very functional and immutable oriented)
This is a great question. I think the answer is, you, as a creative person, need to come up with good abstractions that let you present your idea well-enough without having to do too much work.

I have been thinking about abstraction recently (for other reasons, related to learning). To me, abstraction is transformation of the space with the problem to a space where you can easier manipulate the objects the way the problem requires it. For example, we can have image represented as pixels, and we can abstract it into lines and geometric shapes. So the operation, such as moving this triangle from here to there, that would be complicated in pixel representation becomes trivial in the more abstracted, geometric shape representation.

Back to the original point. Here are some examples of people invoking abstraction in order to solve some problem:

E.F.Codd invented relational model (abstraction) for databases. It let him solve some issues that people struggled with before (how to organize data and build queries) more efficiently.

Jeff Dean invented the map-reduce paradigm of distributed computation. The original map-reduce implementation was only about 1000 lines of code.

You can also see that abstraction has a cost - it doesn't let you do all possible operations more efficiently, just some that you might be interested in. It's a trade off that you have to make in order to present your idea to the world, to make it work. However, the point is to solve enough with the new abstraction that other people take notice and will naturally help dealing with the complexity of the edge cases.

There are many other examples of abstraction from computer science (for example, high-level languages), and even more examples in mathematics. It's how many mathematicians conduct their business - trying to come up with new abstractions (new definitions) that let you handle complicated proofs in a more straightforward way.
