In fact optimizing the Falcon 9 for first stage re-use has lead it down a very different development path from most modern launchers.

On an expendable architecture the priority is saving weight on the second stage, because every kilogram saved there saves many kilograms for the first stage. So pound for pound the second stage usually costs more than the first stage. Also the cheapest way to build a first stage is with one or just a few big engines. Both these optimization criteria are reversed for a re-usable design. In the Falcon 9 the first stage is re-used while the second stage isn’t, so that’s the stage you want to spend your money on. Also a few big engines can’t be throttled low enough or gimbaled precisely enough for a landing burn. Even the using just one of the relatively small engines in the Falcon 9 can’t be throttled low enough to hover. Hence the Falcon 9 has many smaller engines to give it a much greater range of thrust settings and better attitude control.
Ofc they will fail at some point, there is nothing magical about a self-driving car. What I meant with the previous post is that it could be fail-operational see for example the volvo drive-me.
I think it's probably because traders who actually trade options for a living know how to use existing laws to minimize their tax bill.

The people you are talking about in startups are likely the tiny minority of people getting screwed, while seasoned traders use all sorts of tactics to have a very small tax bill at the end of the year.

John Muratore now works at SpaceX, but this is a pretty good interview with him during his NASA days.

There's a particularly enlightening paragraph about how he retooled Houston's mission control using the "pirate paradigm" and the "build a little, test a little, fix a little" philosophy. Even though this was back in the 80's, it seems like the kernel of more rapid/agile/test-based dev process that's well known today.
Enormous parts reduction: Much less labor to assemble, much less ongoing maintenance. I feel like this is so much more critical and has much larger ramifications than other second-order consequences.

It does more than that. AWS or Linode are not, to my knowledge, deploying the sort of intrusive, ad-centric deep packet inspection that Comcast, for instance, is. It is also a layer of separation from your actual IP address, which is worth less than it may seem at first, but helps.

Of course, that could change if everyone starts using homebrew VPNs. That's a bit hard to imagine, but stranger things and all that.

I'm feeling really manipulated by the media here. So if I am understanding this correctly, this is what ISPs have already been doing forever, and it will continue. There was a new rule put in place to increase privacy protections, but it wasn't in effect yet, and that rule is what is being rescinded.

So the status quo is being maintained, Telecommunications Act already makes it illegal to sell personally identifiable information, and there is no browser history apocalypse coming.
What are you using to judge the quality of the sub?

I can name many subs that attract some of the top members in the world in that field. If you are fascinated by rocketry, then yes /r/spacex is going to really impress you.

There are knitting subs attended by the top knitters in the world that write the knitting books everyone else uses. But I think it less likely to impress you if you don't value knitting as a skill, like you value rocketships.

Track Our Startup – Ep01 – S01
I am not Einstein but in my 40s and definitely doing a lot with my time: on one side it was hard commitment and fierce hustling for 15-20 years in the past, on the other side hustling increases efficiency and high-level productivity dramatically, so that I can now do a lot (and well conceived / designed) in a very short time. Low-level implementation is invariantly slower though, be it by yourself or delegating. As an analogy with more talented people, I suspect scientists finding their Eureka! moments easier worked very hard for a long period in their past.
On the other hand, people have gotten curious in the past. If I wanted to hire innovative top talent, I would expect them to have interests outside the immediate company project requirements.
Actually most good ideas come from domain experts and not some business managers.
Furthermore, many people just naturally like to share their ideas and discoveries to the world.
> If you look at nature ~50% (various research points to 40% to 60%) of fertilized eggs are lost before a woman's menstruation cycle. So half are lost without attaching to the uterine wall and anybody noticing it.

That strikes me as a bit of an unfair argument. I can't speak for all religious people, but for many there's a huge difference between losing fertilized eggs 'naturally' and inducing this outcome. Within their world-view, this distinction makes sense.

> So the whole ethical concern about copper IUDs and preventing nidation is a misguided at best. And more realistically, it is a harmful and outdated belief clocked in arbitrary religious rules ... meant to exert control over women and families.

While I agree on the arbitrariness, and while I'm not religious anymore, I once again don't think it's fair to argue that 'realistically' these beliefs exist to exert control. I'm sure many people have used religion to exert control, but most of the deeply religious people I know can do a decent job arguing why they believe what they do, I just disagree with their axioms.
Here's the question though: Why don't ERs have a billing code that is essentially a walk in visit that costs a sane amount?

My vague understanding is that the answer is along the lines of "they don't understand economics" and have worked over time to push lower risk care out of the ER, instead of working to handle it at lower cost inside of the ER, making the typical ER visit more and more expensive to handle...

The architect of the ACA literally said the same thing about hospitals, moving services out of the hospital where possible to save money. But that just means that either the utilization of the hospital goes down (driving up costs) or the complexity of the care delivered goes up (driving up costs).
1. If you can pay for around 24.6 hours of VA speech data, you can get enough data to run this process with the same quality that Google presented. (that's from the "Experiments section") Not cheap (definitely not free, especially considering the amount of quality control you have to apply), but not expensive either.

2. You can rent out a 96GB GDDR5 GPU instance from Google's cloud for pretty cheap. (https://cloud.google.com/compute/docs/gpus/) I don't think you need anything more powerful than that (but feel free to prove me wrong).

I think your last paragraph is totally misguided/uninformed. You can download models for cheap/free (for non-commercial/edu use) from UPenn (https://www.ldc.upenn.edu/language-resources/data/obtaining). People don't give away models for free with 0 strings attached because they're a pain to make.

And if you want something you can run on a home computer for cheap/free, you can try DeepSpeech: https://github.com/mozilla/DeepSpeech. All you need is an Nvidia GPU.
I have Vue and I really like it. It's nice to use on the PS4 and even the Windows browser client is good.

But I pay just about the same for it as I paid for a cable package...so at the end of the day I'm not sure what the victory is other than not having to use a set top box designed in the aughts.
TL;DR: Yes.
> Similarly, knowledge of the future was incompatible with free will. What made it possible for me to exercise freedom of choice also made it impossible for me to know the future. Conversely, now that I know the future, I would never act contrary to that future, including telling others what I know: those who know the future don't talk about it. Those who've read the Book of Ages never admit to it.

That right there pretty much sums up the point I had trouble with. How does knowledge make it impossible to exercise free will? Or since it's stated the other way around, is it that you just don't know the things you would be compelled to change, so it's not that you see all of the future, but that you only see the future that you can't or won't change?

In any case, I find "Conversely, now that I know the future, I would never act contrary to that future" hard to accept at face value. I find it hard to reconcile how free will will coexists with a system like this, since I imagine someone will try to fight that purely on principle. Maybe those people would know little or nothing about the future though, since their desire to change it would prevent it's knowledge in the first place.

Finally, "including telling others what I know: those who know the future don't talk about it. Those who've read the Book of Ages never admit to it." is odd to me. Why do they not talk about it? To me, this implies a lack of free will, otherwise again, someone would talk about it, even after the fact. Is it really that people do not or is it that they can not, because I can't really see do not being followed.

In the end, I'm left with a very muddy and inconsistent view of how this works because of those explanations. Then again, doing this well may have been an impossible task for me. If there isn't an explanation that blends free will and knowledge of the future that exists, or in a way I can understand and accept, the alternative for this story is no free will, and while consistent, it's also bleak and disconcerting, since I'm not sure there's much that's quite as bad as knowledge of the future and along with it knowledge that you can do nothing to change it. Either you never want to change it, which points to sentience being a lie, or you do but cannot, in which case you are a prisoner in your own body. :/

Company managers have a responsibility to consider numerous factors when designing a total rewards strategy (pay + benefits + career opportunities/work environment). Among these is to deliver rewards using as efficient a currency as possible. When the perceived value of a pay element (or benefit program or perquisite) exceeds the economic value, then a company should deliver more of the total reward opportunity using such currency. Many companies have determined that perquisites are valued more highly by employees than the economic cost to deliver such perks. (Same for the perceived value vs. economic value of equity compensation.) By "underweighting" employee benefits, perhaps companies are actually choosing to deliver their total reward opportunity more efficiently than those companies which have more "market competitive" benefit programs.
Differentiation of HR strategy is not automatically wrong.
You are not factoring in costs that will one day materialize.

Believe it or not, one day many people decide they want to have kids. To send them to a decent school in the U.S. costs money. I've seen $10k for K-12. That's 13years of $10k per child. So 3 kids = $390k U.S. That's $U.S. dollars and after taxes.

Then there will be a day where you get laid off. The AI/ML industry will suffer a downturn at some point. In the U.S. your severance will be tiny (?2 weeks salary?), whereas in Canada it will be a minimum of something like a month plus 2 weeks per year of service - but often much more than that. So 10 years of service will be provide 24 weeks.

Vacations - in the U.S., 2 weeks seems common, but many Canadians enjoy 4-5 weeks of vacation.

Then there's the increased crime and violence. Guns in particular. In the U.S., if you want to be as safe as Canada, you need to live in a gat

It is intentional. There are creepy providers out there that really want you to use their DNS so they can surveil/gaslight you, so they block or redirect traffic to well-known DNS ports.

Putting it on 443 forces a choice between letting people manage their own DNS or blocking every store on the planet.
The message isn't encrypted for each device; the message is encrypted once for the room, as part of a 'session' of messages - and then the key data for that session is shared with the devices who are allowed to read it. Thus you can share old session key data with other devices if you want, meaning that new devices /can/ see old messages, although we're still working through the UX for that. (Currently the only way to do it is by import/export session key data in settings and transferring it between devices).
#2 is illegal under Medicare/Medicaid rules.

We are required by law to charge the same price to all payers, including patients. We can't offer a cash discount at the time of service, as it is Medicare fraud. We can charge you, accept a lower payment, and then write off the rest as a loss.

In your example, who is this magic insurer? Which reimbursement rate are we setting as the bar? I hope its not medicare or medicaid, as they often reimburse below cost.

Is it the highest negotiated reimbursement a given imaging center has negotiated?

Each of these contracts are negotiated individually between the payers and the imaging center. Because of the variable reimbursement and the federal requirement that one price be charged to EVERYONE, you see huge markups lest you undercharge a payer that would have paid the full amount.

ESPN is honestly the single biggest selling point FOR cable. If not for ESPN I'd have cut the cord long ago. Live broadcasts to millions of people at the same time make tremendously more sense in a broadcast model than a TCP connection per viewer model.

It works fine for sporting events that are expected to have fairly low viewership or for content like Netflix which gets preprocessed and pre delivered to closer-to-viewer nodes. If I'm trying to watch Clemson vs Alabama in the national title game and the feed goes out because so many people are trying to watch it at the same time I'm not going to be a happy camper.

Ask HN: Negotiation advice with top tech companies?
Hi
I was lucky enough to pass the standard software engineer interview with 3 of the top SV tech companies (think Google, Facebook, Apple, Netflix, Amazon). I have about 7 years of experience (some titles held: Software Engineer, Tech Lead, Engineering Manager), and the various recruiters handling my case said the feedback from the various interviewers was generally on the strong/very strong side.

Problem is: how much can I negotiate?

In my current company (medium stage startup) my total cash comp is about $200k and I have unvested equity in the form of stock options that are valued on paper at $~1M (based on the price the investors paid for the last round) and, while the equity is obviously illiquid, the company still has a very considerable growth potential and the business is going well. I already vested a decent amount (not included in my calculation above), so if I leave I would capture to some degree the upside of a liquidity event, should that ever come. I am interested in leaving my current position purely for new technical challenges (I am experiencing a very mild form of burnout due to the lack of new exciting projects), but I am not so desperate to accept a lowball offer. In other words, my BATNA is reasonably high.

In terms of offer, what I have gotten so far from one of those companies is:

- $180k base salary

- $200k RSU package over 4 years

- 10% target performance bonus

- $25k signing bonus

Considering my unvested compensation, this seemed low, so I told the recruiter that and, after a couple days, he came back with more RSUs (total package $300k now). How more can I play this game? It would be nice if the RSU package could get as close as possible to my current potential unvested value, but I don't know if that's even possible and if that would have other negative effects (e.g. unreasonably high expected performance level, so that I would be an easy target for termination after 11 months?).

Any advice would be great.
Good point, otherwise cheating would be a valid strategy (ethics aside).
Tree diff varies between O(N^2) and O(N^4) for simple solutions of varying complexity of matches possible, with a complex fully general algorithms coming in at O(N^2 log^2 N).

Tree diff is harder because the range of operations is bigger.

React.js cheats by insisting on keys for arrays so matching is much easier.

> Not everyone is interested in across-the-board reduction of government power. I understand it appears to be your view, but you need to be careful to treat that as another political position, not as a global constant.

It kinda depends on what you mean by "across-the-board reduction of government power." I do believe that everyone is interested in peace. And justice. And creativity. And hope. And being able to relax and do what they want.

And even if government isn't in opposition to these things in every case, empire certainly is. And people recognize that.

So yes, deprecating the American Empire is something that enjoys very broad support; certain aspects enjoy consensus.

I hear people say how important it is to participate in the political process. But when the process itself is broken, what's the point of participating?

We can vote alright, but what we are actually voting for is the person who is the most convincing liar and makes the most appealing "promises", without them being obligated in any way to actually implement their promises once elected.

As I see it, individuals only have a couple of effective ways to influence politics:

- withdraw your financial participation in things you don't agree with. This is extremely difficult: most people are not willing to endure the sacrifices necessary, and we're not coordinated to do it together. If everyone (or even 10%) canceled their Internet service, cable service, or whatever, for 1 month, THAT would get attention. If 10% were willing to lower their standard of living in order to reduce the government's tax take by 10%, that would get attention.

- regular individuals need to donate more money to politicians than corporations and wealthy individuals. It's a sickening thought to me that the only way to get public servants to actually serve the public is to bribe them, but obviously that works.
Ask HN: Does anybody follow the Pomodoro Technique religiously?
I happened to watch the video on Productivity by Robert C Martin (author of Clean Code). He recommends following Pomodoro technique everyday to estimate our avareage number of tomatoes/day on the long run and also achieve the benefits of high productivity. Has anyone followed this? If yes, what are your estimates and have you reaped the benefits?
But you're treating the symptom then. Shouldn't the illness be the target?
Is that so? I have never seen a hospital in my life without an ER. Most hospitals in my area loudly advertise their ER even from the interstate.
