> That means investing in poor neighborhoods and undeserved communities, providing equal access and opportunity and removing as many barriers as possible to those who have been traditionally marginalized.

It seems to me that precisely the worst forms of that are the ones promoted most heavily. It is not difficult in the slightest to test a person's financial means, and that is the best proxy for the kind of inequality you're talking about; but American (and Canadian) schools tend to focus on imperfect, politically-charged metrics of "marginalized" (usually mainly race).

Since the current forms of this kind of policy tend to mainly attract racists (the subtle, erudite kind), they tend not to address the broader issues, and they tend to push away true progressives.
Launch HN: Black Brook, ethical consumerism launch
Hi HN,

I'm Tys, founder of Black Brook Apparel. My vision is to build a mixed-revenue model clothing company with responsibility at its core: to workers, to the environment, to customers. The HN community has a wealth of knowledge on every aspect of business and startups: I welcome your feedback, advice, enthusiasm, criticism, etc.

I'm currently funding our first product in Kickstarter (http://kck.st/2SbREJx), and building our team.

I study economics and politics at Tufts University and I've always been an entrepreneur. I'm more of a supply chain guy than a coder, but I've worked with tech startups before, including a great food delivery company from Madrid, and these experiences have informed my own business ventures. I'm driven by the desire to build something and a respect for the natural world, so after going back to the drawing board many times, that's what I've designed with Black Brook.

My dream is bigger than a simple eco-friendly clothing company. I want to deliver real affordability ($100 is not affordable for many people) without sacrificing environmentalism, but I also want to use 45% of profits to fund micro-loans for community development and the transition to renewable energy. The real dream here is broad-scale integration.

The best way to try to start (this type of project) at first is Kickstarter-that way I can easily demonstrate demand to wholesalers. I talked to many factories about meeting my specifications, and now I have a product line ready to launch. Securing wholesale accounts and maintaining a commitment to a sustainable supply chain are my biggest priorities, and of course team-building is just as important. I'm looking for driven people to join my team and help bring Black Brook into the world--perhaps some of you will be interested. As a student, I have so much to learn about business.

I love creating, and though I've started businesses before, this is my first really big project.

I find the use of "we" as a CEO to be disingenuous. Being the head of the company means taking ownership for your company's actions and I feel at that level you don't get to deflect to "we".
You may be interested in https://www.nytimes.com/interactive/projects/college-mobilit... which compares Harvard against "other Ivy league schools" on a typical / above / below average. Looks like just under 5% is typical for bottom-20%-income background for admitted students.

It's also worth noting that Harvard, for example, admits fewer than 3,000 students per year. That means that 100-150 students (out of 40,000 applicants) will come from a poor background.

Seems like being rejected from an Ivy league school is statistically the most likely outcome, regardless of what your qualifications are.
I did $55k USD/year in SF recently. I had great healthcare as part of my job. After rent/expenses I didn't really save any money, but my experienced was preparing me to have a substantive private sector salary after a few years.

I could have cut it down to 40k/year somewhat easily, if I also went for a long commute and gave up some luxuries like eating out. Below 40k I would have had to learned some more serious frugality tricks.
It's actually slightly cleverer than that.

When quicksort recurses into a subarray that is less than the critical size, (call it k) it does not switch to a simpler O(n^2) sort: it simply returns, leaving the subarray unsorted. The result is that the final array is mostly sorted, where no element is more than k distance from its true position. Once the array is mostly sorted, it then runs insertion sort, which is fast on mostly sorted arrays. Despite the fact that in the general case insertion sort is O(n^2), it is O(nk) on this mostly sorted array.

Selection sort performs no better on mostly sorted arrays than insertion sort. Which is why insertion sort is used instead of selection sort.

You CAN NOT screw up. Because if you did, it even won't work or won't build.

> So in practice, 120 VAC or 48 VDC are the limits for household wiring

About 20% of the world uses 110-120 V and 60Hz. The rest uses mostly 240V at 50Hz.

Although 110V is safer, the US seems to ignore many of the safety features I see used elsewhere in the world.

How that translates to deaths per million people per year comparing to similarly rich countries, I don't know.
YC is very Blockchain friendly, Wozniak likes it,Larry Page is mining Ethereum, Jack will bring Bitcoin micropayments to Twitter, inventor of javascript runs a crypto browser now and Reddit CEO loves it too. I wonder why the top comment here is someone that hates bitcoin with all his power. A psychology study will surely be interesting about why some techies hate it so much really.
This is a stupid argument. Say we have 100 people in our economy, 90 of them $50k, 9 of them make $200k, and 1 person makes 1 million. Everyone invests 10% of their income in 'stoks' which cost $5/each.

Each of the 90 people invest $5k and have 1000 stoks.

Each of the 9 people invest $20k and have 4000 stoks.

The millionaire invests $100k and has 20,000 stoks.

The top 10% have 99.96% of the stoks.

It would be weird if the richest people didn't own most of the stocks. It doesn't necessarily mean there's a problem.
>Would incumbent transportation companies have had more time to catch up, leading to a more competitive market?

i'm not sure that in general incumbents catching up leads to increased competition, i think it leads instead to the incumbents protecting their position and using it to stop the innovation and the resulting threat of disruption.

In case of Uber it wasn't about incumbents per.se., it was about regulators. The blitzkrieg allowed to crush regulators and thus increase competition by adding "ridesharing" into the mix.

Similar thing of using your huge weight to crush a chokehold on the industry happened when Jobs took control over phone apps away from the telecom companies.
The headline is flat out false. You can see Netflix financials here:

They paid 15 million in tax for 2018.
We can never be data driven. The important data is what customers will be willing to spend money on next year - we can only make guesses. Data can educate the guess somewhat, but it is still a guess. Will our competition come up with some not patent on a product that is so much better than us that we sell nothing - if so the right answer is for the CEO to lay me off now. Will our new product be enough better with expensive to develop feature X to be worth the price - we can do focus groups and the likes but it is still a guess in the end.

I completely agree, flicker has been the most distracting part of switching to LEDs, for me.

Here are two good sites that posted graphs of light intensity over time for a bunch of different bulbs:
http://www.ledbenchmark.com/

Unfortunately, they both stopped updating around 2015. Anyone know of similar sources for more recent bulbs?
Judging from the text of the article:

> Netflix did it twice, and paid an average tax rate of 13.6 percent over the eight-year period

Carryover losses is the most likely reason, and focusing it on only one year makes for a good headline but terrible economic/policy analysis.
For me it was "sharing".

It was when original content got pushed aside to non-stop sharing and re-sharing of memes and propaganda.
Doing the right thing after significant public outcry still seems wrong.
As the page notes, this is a result of a surveillance transparency ordinance adopted in 2017. Some other cities are considering these; readers could advocate for them elsewhere too.
We have a Thor Class C on a Sprinter chassis. Chassis is awesome, if you have the means I highly recommend one. Thor build quality (and RV quality in general) is laughably bad. I'm confident the "bones" are good, but what's screwed to the frame is screwed on as quickly as possible. I've been through just about every inch of that thing while I was installing and running wire for solar and a big inverter. If it's behind a screwed-on panel (IOW, customer will never see it), there is leftover shit everywhere. Saw dust, wire ends, whatever.

I'm surprised when I go to unscrew something and find that the screw was actually screwed in straight. I'm dead serious, there aren't a dozen straight screws in the whole thing (well, there are now). Assuming the $WHATEVER even got a screw; I keep forgetting to run to Home Depot for screws for those brackets that are hanging by two wobbly screws.

So, yeah, build quality on RVs is shit. But if you can do your own van, you can redo anything in an RV. And the RV is already plumbed and wired, mostly. You can fix the stuff they missed. :-) Despite my complaints, I've put in far less effort correcting Thor's mistakes than I would into building my own van.

We seem to be converging on this sense of the word (Merriam-Wester 4):

> marked by the imaginative or emotional appeal of what is heroic, adventurous, remote, mysterious, or idealized

Surely, even in full context, certain things can be legitimately seen as heroic, adventurous, remote or mysterious without being overly idealistic in an unrealistic way. It seems valuable, to a point at least, to allow our emotional reaction to such events guide our dreams and plans. That's an upside to romanticism.

I'm a fan of SpaceX, et. al. If those outfits had to be funded and staffed by unromantic people primarily interested in return on investment, would they exist?
How do you recommend allocating it, then?

They were caught stealing from their employees/contractors. Did the right thing? They are pleading forgiveness for abhorrent behavior, let's not sugar coat this.
Scientists also warned that we have around 12 years to avoid a climate catastrophe [1].

And some scientists [2] claim the next decade can be very challenging - more droughts which can cause crop failures - causing food security issues and in worse cases some kind of societal collapse, the famous 9 meals to anarchy.

What are your views? Are these scientist just mega alarmist?

Do you worry about climate change in the near term?

Are you changing your strategy, e.g. planning to live more self sustainable and move away from cities?

Do you think we could go extinct this century if the world doesn't take this climate emergency serious and launch something like a Manhatten project to tackle it?

I quit tipping on DD as soon as I found this out about a month ago because it'd almost always be less than $4.50, so wouldn't affect the dasher's bottom line anyway. If I start again it'll be cash, but I don't typically carry that in small bills.

But I'm pissed. I've been a heavy DD customer for years and I'm an excellent tipper. Apparently I've been offsetting DD's costs for quite awhile now thinking "100% goes to Dasher." Bad enough that I have to tip in advance of the service--Uber Eats does this right--but they've been stealing those tips the whole time on top of their "service charge" and "delivery fee". I'd love to see them burn.

It doesn't take a class action--last I saw comparative stats they were only doing well in the Bay Area, San Jose specifically, and were rock bottom of the market share elsewhere. We probably just need one educated market to trash this strategy.
Pretty basic for good leaders:

This is a similar straw man to someone claiming the trend of cars is clearly going electric and you saying "I doubt it, look at all these gas propelled cars we have today".

Python and Javascript are going to be around for a while, sure, but 1) they are also moving toward static type safety and 2) fewer and fewer projects will be started in these languages because statically typed alternatives are a better choice across the board.
I agree, but the US has the wrong cultural mindset for this issue.

The example I turn to -- and I'd be interested in the hard data on this -- is the explosion of STEM education in the US after WWII. It seems to me that a massive institution of STEM education was built on the idea that we needed to "beat the soviets" in the tech race. Ample public funding made tuition cheap and expanded opportunities for huge swaths of the population. But access to these institutions is being shut out by increasing costs. Students pay a fortune in tuition and housing, and yet every intro science and technology class doesn't have enough seats.

I think it's a subtle change that has occurred. The universities don't much care about providing the best possible education. They care about signaling to the market that their graduates are the best, so that graduates can pay their loans back. This is because there is no unified mission any more. We're not engaged in a technological race with anyone, so the institutions only need to perpetuate the signal of quality--not quality itself--to maintain their existence.

We're resting on the inertia, which is slowly waning until we are not the best in the world any more. At that point, the true magnitude of the deficit will become apparent, because immigrants will look elsewhere to be educated.

The institutions that are really picking up the slack here are community colleges. Their resources are dwarfed by the scope of their mission.

"Every enlisted man in the Navy only gets 4-5 hours of a sleep a night" seems to be a common anecdote service-wide, including from people I know personally who served.
I remember seeing this account forever ago and thinking nothing of it. It seemed like another stupid meme account that posted some funny occasionally but mostly seemed pointless/harmless.

These result, generally, in a 120Hz flicker, which some people are sensitive to.
Well, the easiest way is to just not use the service...
That would be more than enough if this was an accident -- but it wasn't. Dropping compensation when a customer tips is a deliberate choice that required engineering time and manager signoff to implement and ship. Building and shipping this feature was a calculated, deliberate decision.

Who made this choice, and how has the company changed things to ensure that they won't make this choice again?
Oh, do tell? Please point me at the scientific and mathematical evidence. I would be interested to see it.
I think that blockchains can provide more trust than the current system because the ledger is publicly visible. The societal system still kicks in to remediate the effects of a mistake but the blockchain is an additional tool used to provide the evidence and support for such a reversal. For me, personally, I think the best solution is a form of blockchain run by a state/federal agency. You're putting trust in an institution, yes, but the underlying technology helps support that trust.

That is actually not normal in the restaurant industry.

In restaurants, tipped workers get a base wage and earn tips on top of that. If they don't hit minimum wage from that base wage+tips, the restaurant has to pay them so they at least make minimum wage. If you have an issue with the low base wage, take it up with your local legislature.

InstaCart and DoorDash are doing something different: they're promising a minimum payment to drivers but that minimum payment is in lieu of a tip. A or B, not A+B=C.
A metal working friend told me recently that in Australia we're not meant / allowed to use fluorescent lights above lathes, as the flicker can disguise movement.

FWIW Rust has "The Rust Book" as their primary long-form documentation, separate from their reference documentation. It's a common starting point for people new to the language. I read it in chunks as I was getting started.

I'm not sure how it compares to those works of the past (perhaps less detailed?), but I found it much more approachable than most languages' documentation and more in-depth than most languages' tutorials.

The old ways may not be entirely lost.

I don't know if requiring a comment for an upvote is so necessary; but requiring a comment (or an upvote of a comment) in order to downvote seems like it could help. I think the problem with upvoting tends to exist where there is no downvoting.

I'm mostly at peace with net scores on my replies, though I feel a bit confused when the scores down without explanation. I think it is healthy to some extent to seek validation, but in order for it to be productive, I think we ought to know why people feel the way they do about what we say.
