> More generally, the reason there are high valuations for companies that are growing users by selling a $20 bill for $18 is that they can drive out all of their competitors who can't afford to burn money.

Which is a prime example why the whole business model is harmful for a capitalistic marked as it undermines any idea of "fair" competition and marked self balancing. (At least in a context where the money burned comes from an external source like e.g. VC, through close to quasi-monopoles spreading to new markets also fall into this category IMHO).
It's not a straight line. Brake Specfic Fuel Consumption (gal/hp-hr) is often higher in the lower 3rd of the rev band. Across the bulk of the RPM range the BFSC curves are basically flat for most engine. Throttle position matters much more than RPM.
It’s OT but I will totally forgive Zoom for their security issues. Their CEO openly admitted they were wrong, promised to fix it, made real changes fairly quickly to better lock down default settings, have upgraded their ciphers, and made a major acquisition to build-out their security chops (Keybase) to address the larger problem of easy to use key management.

Personally I’ve relied on Zoom to get meetings running quickly (without wasting precious time fighting with hard to install client software) many times on meetings where I would gladly trade ease of use for security posture.

I think Zoom messed up but has shown they can admit fault and course correct.

They are—as far as I’m aware—an entirely content neutral communications network that lets me pay for a service, doesn’t try to analyze and data mine my content, isn’t operating as a middleman between me and my customers, and isn’t at risk of becoming my competitor if it detects my product is becoming successful. They aren’t leveraging a monopoly position to maximize rent seeking and crushing the little guy through arbitrarily enforced content moderation policies. They aren’t exploiting cheap labor or phish a business to intercept their customers.

So as far as growth-hacks go, playing some API tricks on Mac and Windows to get their client ridiculously easy to install and running in a meeting — which risked you entering a meeting without an extra prompt, or potentially provided a pivot for unsigned code....

Frankly they seem about as un-villainous as they come in terms of publicly listed tech companies or venture-backed unicorns.
A moment's study of NYC real estate over the last thirty or even 300 years is sufficient to disabuse one of the explanatory power of supply and demand, except in a very broad macro trend sense that ridiculously oversmoothes the actual data.

Especially recently, right up to COVID times. There were hundreds of thousands of empty living spaces, even more vacant commercial spaces, and virtually no changes in prices.

An important insight is that there are very few markets in the world. Most transactions take place in a context where the players have been playing for a very, very long time, and the game is optimized for the repeat participants. These are mostly cartel games, private contracts among the heavies. Not markets.

In particular, real estate in New York is a subsidized game of capital and patience. It has been so since the 1700s. At this late stage there are only benefits and virtually no penalties for holding a property vacant. Property taxes are vanishingly low. Claims of loss from vacancy are used to reduce business taxes. I could go on but you really should do your own research.

It astonishes me that people can be so convinced by a model, especially such a facile one, as to disregard actual data.

Best wishes to you.
It depends on the type. The most common type, Obstructive Sleep Apnea sounds way worse than loud snoring. If you've ever heard it, it's like the person is suffocating while they sleep (because they almost are).

Sure, I have nothing against getting enough sleep but the book's first 10 pages contain so much misinformation and given that Walker outright falsifies the data in the book (https://guzey.com/books/why-we-sleep/#appendix-what-do-you-d...) I would struggle to call it anything other than bullshit.

Yes, I believe that you should take this factor into account while reading my experiment. As I write:

The main thing I miss from OS X is Droplr (pain free sharing of annotated screenshots) and Jumpcut (pastebuffer history tool). Can't find anything on Linux for either of those that works nearly as well.

I'm not a lawyer either. As I understand it, the design document itself is protected by copyright, but the physical device itself is not.

I think the reason for this is that copyright and patent law exists to promote the advancement of the arts and sciences. When copyright covers a work it also covers smaller portions of it. With machines there's often only a few efficient ways of making it work. If those were covered by copyright then everyone else would have to invent new ways of doing the same thing. You can get a patent on a novel machine though, but patents last for much less time than copyright does.

It's a bit like copyrighting an API and then everyone else has to rename their math.min and math.max functions.
Nobody except newcomers to the codebase look at documents on code structure, and of course no one is fired for not producing it/producing a crappy version of it.

When the newcomer can't get anything out of that doc, if it exist, he/she just need to ask the creator, who will explain very nicely how everything is done, and that newcomer become a code guru in that codebase, and the cycle continues.

There needs to be a more sustainable model for scooter rentals than "when the scooter breaks, we just throw it out and replace it with another $20 white label scooter from China"

The reason they're treated like trash, by both the company that put them there and by pedestrians, is because that is what they are.
Yeah and the perverse incentive here would be to avoid these kinds of stats by....not actually policing much.

You can't derive story rank from timestamp and point score alone—the system is more complex than that and includes many countervailing factors, including user flags, software downweights, and moderation downweights. All of this is to try to prevent the front page by being dominated by the few hottest and most outrageous topics of the day, which is what would happen without them. I've reduced one downweight, though, so this one is back on the front page now.

There was a huge thread earlier about the rank of this thread and related ones relative to others, which you'll find somewhere in these pages.

Yeah, I did that too, I can get away with most of the task with my skill, I'd say it's 'brute force' method. Though I found that it's not really sustainable and took toll on your overall health(both body & mind) if done frequently. TBH I hates how I operate.

I'm trying to create a system that move away to a more proactive mindset about task, the result is still hit or miss, but it's definitely better than pure last-minute-miracle style.

There will definitely be massive reduction in business travel + local commute that makes up a huge chunk of Uber business that is not coming back. There is also a risk around politics, as we get into election, Uber is going to be a prime target for the Democrats, the legal bills are going to pile up pretty quickly.

I definitely think there would developers ready to use your API.

Hope you will expand beyond Slack. We use RocketChat. But I assume the other platforms will be a priority first for you.

Good luck growing the company by the way and offering a non-FAANG alternative.
If you find a tool you like, check the offerings of the sub-brands from the same group. The mechanical difference between them might be little to none, while the price between them may vary wildly. Unfortunately you aren't going to be allowed to take them apart before purchase so its still hard to compare the internals, but you can check reviews and comparisons of those products.
I moved to LA in the pre-Uber days. Trips from LAX back home were miserable. When my ex-wife had the car and I needed to go somewhere - forget about it. Taxis were impossible to find, even in the middle of West Hollywood. I really don't like Uber, but they did change many peoples' lives.
Idris2 is now self-hosted
Here we are, its 2020, and intel's single core memory bandwidth numbers haven't really moved at all since nehalem. Despite the additional memory channels, and the increase in DDR bandwidth moving from DDR2 to DDR4 leading to machines with 100GB+/sec memory bandwidth (the large NUMA machines have significantly more).

So, its pretty obvious they are choking off the single core bandwidth to keep a single core from starving the others in the machine. This 100% makes sense for server applications, but for workstation and desktop usage its completely crazy that a single core has 50-60 GB/sec L3 bandwidth, but can only utilize 10-20% of the available ram bandwidth to flush the L3 even when the other cores in the machine are idle.

The ARM machine literally has somewhere between 2-4x the single core memory bandwidth, despite being in a configuration with more actual cores than intel offers.

>I wonder if most end users just don’t care about resource usage, as long as they can comfortably run all their apps, why should they?

It's death by a thousand cuts. You're probably not going to switch your MBP from 8GB to 16GB because of spotify/slack alone, but if you have four electron apps using 500MB each, you're missing a quarter of your memory. That may very well push you to get the option 16GB (+$100).

> Determining which organizational complexity is essential and which is accidental is likely the quintessential hard problem of business.

Three questions.

(1) "What would the impact on our business be if we built the best possible, state of the art feature here?"

(2) "What would the impact on our business be if we half-assed a solution in a quarter of the time?"

(3) "What would the impact on our business be if we utterly failed?"

(Usually, the different between 1 & 2 is negligible. Sometimes, between 1 & 3. Don't ask people to justify success. Ask them to justify why we should spend any more time than slightly-above-failure.)
I have come to the (non-scientific) conclusion that this is probably genetic. I know some people who sleep a lot less than me and seem to be fine with that. I am not fine with less sleep, but I wish I was because I would love to have the extra hours each day.

I thought of this for the first time when listening to a Freakonomics podcast series interviewing major company CEOs. Several of them mentioned schedules where they average 3-5 hours sleep per night, forever. They all seemed to think that was fine.

I think I would be severely ill, maybe even literally die, if I averaged 3-5 hours sleep for a duration of many months.

When listening to that series it hit me, maybe this is a genetic thing. In the same way that you kind of need to be tall to make it into the NBA, maybe you need the "minimal sleep is okay" gene to make it as a CEO or rocketship founder. People with those genes get anywhere from 10-20 hours more time per work week than I do, and that's a big advantage over one week, let alone compounded over a career.

I don't know what the research says about this, but my lived experience makes me think it's pretty likely, and unfortunately that also means I may have to be more realistic about what my body is and is not capable of.

> Pointers are an exposure of the underlying computer architecture. Whereas references are more of a property of common language design.

Sorry, I just don't follow. How are the pointers in Go more exposing of the underlying architecture than a reference? (I'm using Go as an example to make it concrete, but any language with similar properties will do).

The syntax and some of the semantics of assignment and rebinding are different between say go pointers and python references, but that's the point I'm contesting, I don't see how one is necessarily higher level than the other. If you put automatic memory management, null pointer checks, removal of any "undefined behavior", pointers aren't necessarily low-level. It wasn't the pointer, it was the memory safety.

I personally think that once you tease it out that it becomes a semantics argument that unfortunately doesn't shed much light on what is "high-level".

Someone wanting to purchase and hold NYC real estate is still demand that would have to be outpaced in order to reduce prices. If you could somehow wave your magic wand and over night there could be 100x as many total units in NYC, do you believe prices would hold steady? Of course magic isn't real, it's just about questioning whether, in principle, there is some threshold past which the price would drop. If so, the model holds.
I am somewhat surprised and taken aback by the level of negative comments in the thread...

However, I suspect that the article “touched a nerve”.

In my experience, the “stronger the reaction” the more likely something is there (think Lean Startup). The opposite of love is not hate, but indifference.

That said, I will echo/slightly modify some of the positive comments I read: it isn’t about being “abnormal” in working 20 hour days. It is being abnormal on where you spend the time you have.

Most of the extremely successful people I know personally dont accept “reasons” for why “x didn’t occur”. I think one of the famous quotes from Steve Jobs at Apple was that once you reached a certain level (VP?), no reason is good enough, it all lands on you.

Or to paraphrase my advisor: “How do you know someone wanted something (past tense)? They got it.”

Not everyone can be abnormal. By definition, 95% of folks can’t be. The question is: What do YOU want for yourself. What is important to you that you will fight for?
For me personally, it has meant to have a meaningful family life AND a meaningful career. It hadn’t been easy. It took many short term sacrifices and focus on the long game. But in general, I have what I wanted.

Examples of sacrifice: taking a “lower paying job” so I would have more freedom to pursue what I thought was important. Going “part time”/passing up opportunities so I can be with my kids while they are super young. Taking “risks” in jobs that weren’t really “sexy” on the face of it, but had the potential for long term impact.

I mention the above to say it can work (but even now my life is far from perfect). The key however (Per the original article) is to adopt a mindset where you are in the driver seat and conversely are responsible.

By focusing on what you can control, and not wasting energy on what you can’t, you free up resources that compound over time.
To make this concrete for folks: let’s say you spend 10 mins a day on thinking how “awful” <insert pain point> is. In the course of a week, you would have spent an over an hour unproductively. Over the course of a year, over a full work week. What could you have done with an extra “week”?

It doesn’t take much, done repeatedly to make a profound difference on your life in the long term. The question is whether you are willing to.
