SpaceX Commercial Crew will cost 55M per seat for NASA. Add to that need need to amortize 2.3 billion in development financing that NASA has given out (includes 2 astronaut flights). SpaceX can sell the other seats on the capsule.

They payed almost 90M per seat for Soyuz at least in the last couple.

In comparison, the program cost of Shuttle per flight was 1.5 billion per flight. They would almost never fly more then 4 people on those flights (just as Dragon can also take 7 people, but NASA only takes 4). And the Shuttle was not getting cheaper and the flight rate was not getting faster.

NASA of course has 2 contractors the other was 4.2 billion and the per seat cost is somewhat higher, not sure exactly with the numbers, like 70M or so.

What the per seat cost overall cost are we will see over time. After the initial maximum flight Commercial Crew contracts run out, NASA can renegotiate after that initial contract and likely get a lower per seat price then.

We will see what the end-to-end lifetime per seat cost are for NASA.

I can't give you perfect numbers for perfect Cargo without a lot of research. It depends if we are talking CRS1 or CRS2 contract and there are 3 providers that are all somewhat different, different proportions of up-mass, down-mass and other capabilities, some that the Shuttle didn't have.

The Shuttle could theoretically transport a huge amount of unpressurized cargo but if you are not building a Space station its hard to actually utilize that space fully. So an analysis would have to include the actual payload and so on. That is getting to complex here.

What NASA values seems to be having much less risk on one system. Having different vehicles on different rockets and being able to deliver what they want when they want it and get it back when they want it back.
I had to post this link exactly 7 days ago. Is there some misinformation currently being pushed in the climate change denialist bubble recently that accounts for the sudden questioning of the validity of historical modelling?

Yes I'd certainly use isopropyl alcohol. I'm pretty sure I can get it with a purity of 95% or more at my local pharmacy.

Dry ice is the other problem it's not something readily available in my town. I don't think regular ice is cold enough especially when using isopropyl alcohol which isn't as volatile as methyl alcohol (methanol).
Betting on that now is insane.

We haven’t even felt the main wave of bankruptcies and disruption yet.

Credit is locking up (try getting an unsecured loan) and people aren’t paying bills. 50% of New York tenants didn’t pay rent. Every seasonal business is dead. Life looks ok for IT people working in their underwear right now, but we are heading into a very challenging time with fundamental changes in consumer behavior.

The next big thing will be underwater mortgages.
I’m always looking for better tools. For informal projects Trello or GitHub issues works, but if I ever have to track anything, it isn’t easy.

I went from MSProject and ClearCase to Jira in the mid 00s and thought it was so much better. I’ve gradually changed to hate it, but can’t find a better tool.

The alternatives I’ve tried have been way worse in terms of complication, cost, and specialized training required. I work with people who use MSTeams and it makes me yearn for Jira. I’ve used GitLab, but it’s cost is too high for non software projects.

It’s weird how this seems so simple that there would be a clear default tool that just captures user stories, routes them among people, and gives reports.
SPX at ~1600 so that CAPE matches its historical median. 1600 would be the "neutral" position on that metric.

And, if history is any guide, SPX can fall all the way to ~500 without breaking all time lows on CAPE (this would be extreme, but is not entirely impossible, and inflation is not required for this scenario - look at 1950s).

Numbers would have to be adjusted if inflation speeds up. It hasn't sped up at all yet, in fact all we see today is deflation.
I think you confuse simplicity with overt verbosity.

There is no reason simple code can't have higher-level constructs. The interface to them is just likely very domain specific, and you don't start with them.

But after you notice you are copying the same sort of code to a third place, you usually notice a pattern, extract that pattern (with no abstract frills attached) to a unique implementation that can be used everywhere, and move along.
Does this mean they have immunity? Is it a false positive?
Wouldn’t directly linking system calls make every address space more unique and thus make it harder to write (generic) exploits for?
> Notice identifies the year of first publication

Oh, I didn't realize this. I always thought I should use the current year as the copyright year. My impression was that using a year in the past makes it look like the website hasn't been updated for a long time, or that the website owner doesn't pay attention to detail.

Should I always be using the first year in the copyright footer on my website, instead of the current year?

I just looked at some very large websites (e.g. Facebook, Twitter), and they all use 2020. Maybe it's just better to follow this convention.

Ask HN: Are GatsbyJS / Next.js “worth it?”
I know this is a highly subjective, and possibly loaded, question. But here are the related questions at the back of my mind when I ask this:

- Do I really need to use React (a client-side framework) to generate static websites? What's wrong with Ruby + Liquid (that I'm familiar with), or anything similar (Python, PHP, etc)?

- Assuming that the static website doesn't include a lot of JS in the first place, exactly how much faster is the Lighthouse/PageSpeed score for static websites built with Gatsby/Next JS? Are there any benchmarks available? Do these frameworks optimize the CSS delivery as well (remove unused CSS, inline the CSS, etc)?

- What are the chances that the JS community will jump to the "next new thing" in 2 years and I'll be stuck with a pile of unmaintained mess?

- Are there frameworks for Ruby/Rails that do a similar job? Does Jekyll (or Hugo) come close?

- Are Gatsby / Next JS really for static website, or for mostly static websites with a sprinkling of dynamic elements (eg. e-commerce, travel booking, etc), that people unnecessarily wrote in React, and ended-up creating a problem where none existed?

- What is truly the sweet spot for this kind of technology? Google search results are full of blog posts where people are just discovering these frameworks (or by companies who are pushing them).
Have you made any non-trivial use of the Qt bindings for those languages? Qt is a big and complex library, and most bindings are incomplete or poorly documented. As far as I know, PyQt is the only Qt binding is the only one that you can really rely on to work now and in the future.
I see. I'm interpreting the DoJ's choice as a claim that Google is the most harmful monopolist in the US, since they've chosen to go after Google (and not anybody else). That's why I wrote my original comment. However, that's not actually stated in the article.

I think my interpretation is reasonable, but I get why it's whataboutism in a discussion of the topic "is big tech monopolistic?".
Thank you so much for CoffeeScript! I bet on CoffeeScript in 2016 and surely would bet again in 2020, it is still great for those who want to focus on compact and clear coding. Your creation helped unknown developers like myself to actually find frontend coding bearable.

After seeing video with you talking about CoffeeScript design aspects ( https://www.youtube.com/watch?v=DspYurD75Ns ), it was clear that CoffeeScript was created by genius. I think the explanation why big corps did not contribute to your work is simple: they just could not. CoffeeScript was perfect from the start. It was ahead of time when it appeared and now it is still ahead of time for features you mention. It is like SQL or functional programming or algebra. Often best tool to get things done, but not for everyone.

If you ever read this, may I please ask one question? Imagine universe where all software is commercial. How much would CoffeeScript cost to its users?
Hello Guys,

Me and my co-founder having hard time to find great resources because of noisy web , and to organize our pile of tabs. So, we build a place where like minded people can share best resources under a subject as a collection to teach one another and store their links whether privately or publicly.

We were frustrated by tab pile in our browsers and also we hate to lose time on fluff content.

*we didn’t have time to change actual landing page so we used our old website builder account to create new landing page but actual sites name is jooseph
oh ya thats very interesting, i feel like the majority of websites just use the current year
With Java I've seen coding standards that you can use `var` only when type is obvious from declaration. For example:

var person = new Person();
var car = selectCarById(carId); // Car

if type is not obvious, it should be explicitly declared.
> which I understand to be "only a monopolist would make it easy for consumers to choose a competitor"

No, not "only".

The argument is that while non-monopolists have a motivation to add those choices, monopolists have a motivation too.

Therefore seeing the end result isn't very strong evidence for whether something is a monopoly or not.

It's good that doctors and scientists are learning more about the virus, which will help them improve the standard of treatment, so I welcome this discovery.

On the other hand, I find that the style of reporting contributes to the irrational panic and fear around COVID-19.

Only a tiny fraction of those with COVID-19 are admitted to the hospital, a third of those develop blood clots (assuming the reporting is accurate), and, presumably, in some unknown fraction of those cases, the blood clots cause death or permanent injury.

However, people will focus on this "1/3 of people get blood clots!" number, and their intuition about the risk of themselves or people they care about being maimed or killed by COVID-19 will increase irrationally.

What it's like to fly in the US right now
It is in there under the "With the pandemic, now the food supply has been exposed as too consolidated. Even hedge funds are saying it, when hedge funds are worried you should be worried as these are the wealth extractors." [1]

Too much consolidation and waste due to super efficiency that is inflexible like code that is too coupled and specialized for a certain cpu over being flexible.

Right now pork is being wasted as slaughterhouses and meat packing has been reduced dramatically in the US since the 90s, larger facilities, less of them. Too efficient that it created a security issue and potential national security attack vector. Everything is not as localized, so there are choke points in our food supply that become massive backlogs.

>In 1977, the four largest meat processing firms constituted just 25% of the market, claims Bond. Today, they control 85% of the slaughter market, as well as some 35% of cattle ranches and around 65% of the entire chicken industry, he said.

> Since 1990, the number of slaughter houses, excluding poultry, has declined by 46%, from 2,709 establishments to just 1,461 establishments.

My amateur guess is the stock prices are being adjusted for the implied inflation due to trillions being pumped into the economy.

The stocks are not worth more inherently, you just need more (depreciating) dollar units to describe the price.

Everyone should earn more. The best thing you can do for the economy is giving ordinary people more money.
The "AI" part here is a bug, not a feature. I wouldn't have to do it if I had an API for sending requests, or a condo-provided app, or at least if the concierge service used e.g. Telegram officially. Since neither of these is true, I had to resort to a workaround.
For me it is either US stocks, gold, or bitcoin , or USD / EUR. Central banks have made it clear they plan to destroy your wealth. Bitcoin is still frowned upon, gold is out of reach, so what's left?

Sure, US stocks is a pyramid, but Euro stocks have been and keep performing very bad. Only china could surprise the world , but they are not going to open up their economy anytime within the next 2 years.
Does this mean that it was much more contagious than thought, if it spreads so fast while so many already have some immunity? Also, if 1/4 of New York City has already had covid-19, then maybe there is only ~1/4 left who wouldn't have immunity. Which would imply that if all restrictions were lifted (in NYC) the "curve" of new infections would be much lower than the first one.
Variadic templates are essential for simple, argument forwarding template functions. std::vector::emplace_back is a very simple example, this kind of use comes up now and then during work.

[1] https://en.cppreference.com/w/cpp/container/vector/emplace_b...

edit: This also shows that you don't have to be able to write variadic templates to reap the benefits of it. You can enjoy the benefits while using a library that uses it.

One thing that I don’t see addressed in these posts, but I think makes a huge difference, is that the stock price reflects global demand for ROI. It’s entirely possible for stock values to go up while SP500 expected profitability goes down if the expected profitability of other markets goes down even more, shifting money out of Europe/HK/Japan into the USA.

Aka you don’t have to outrun the bear just the other guys.
It is never semantically important (in a context that is multithreaded anyway) because you don't have more control over scheduling with async/await than you do with Loom's virtual threads. In either case, the code doesn't know if scheduling takes place on a single kernel thread or multiple ones. Nor does it know about the existence of other threads running concurrently. There could be some technical differences, like various GPU drivers allowing only specific kernel threads to use it, but Loom answers that with pluggable schedulers.

The difference in the native call case isn't semantic; it's, at worst, a difference in performance [1], and as far as I know, no one is making that distinction today, so there's nothing to erase. Moreover, as Java doesn't have async/await, there isn't even an artificial distinction to erase.

I don't know all the reasons Java abandoned green threads. One of them was that the classic VM that had green threads was simply replaced with HotSpot; it wasn't an evolution of a single VM. But more practically, and putting aside the fact that it was M:1, at the time there Java code relied on native FFI a great deal, whereas today it is very rare in general.

[1]: This is a little inaccurate. There could be a difference in liveness properties (deadlock) in that case, but neither async/await nor kernel threads, for that matter, make intrinsic liveness guarantees. You have to trust your scheduler in all cases.

When the content changes, that new content is under a new, and current copyright. So most of the time using the current year is legitimate.

Of course, it’s probably just automated, since updating the copyright with changes once a year is probably too big of a pain.
Unfamiliar with the man beyond basic things like the Game of Life, I had his biography on my to read list for a while. His passing unfortunately propelled it to the top of the pile, and I read it in a few days. Conway truly was a once in history kind of person, and the biography feels so casual yet intimate - it feels a little bit like having lost a friend.

Since, I've been slowly diving into the various books and papers he published - they are all awe inspiring. His proof of Morley's trisector theorem is stunning - I can't wait to share it with nieces and nephews because it is that straightforward, it literally can be taught to young children. A proof for a theorem that stumped all mathematicians for over a century. Just utterly stunning.

I have "Winning Ways for your Mathematical Plays" coming in the mail today. Can't wait.

Traditionally C++ code is often considered harder to read than code in these other languages, and the "excessive" use of 'auto' does not make understanding code easier. Still, according to my observations the split in opinions on this is about 50/50; mine is that the use of 'auto' improves the "genericity" of code (on par with the use of templates) and its amenability to refactoring with less chance to make a mistake. As to the readability of code, it also improves due to not having to repeat yourself as often - as long as the names of the variables remain self-describing or are clear from the context.
Which stock? If you want to price any individual company, traditional value-based analysis using earnings, assets, and future revenue growth expectations will get you a number. This number varies wildly between different companies. If you're talking about a broad index like the S&P, I personally look at 30 years of price history, draw a best fit line to average out growth to a normal level, then discount 7% for our current economic trough (5% output drop Q1, likely 10% or more this quarter). By this method, S&P should be somewhere around 2150.

The problem, of course, is that we've been in an unprecedented financial situation since 2009 fueled by massive debt inflation among corporations due to near-free money from the government for an entire decade. When will the party end? Who knows. The other problem is that it's hard to predict what will happen post-lockdown globally. As a result, traditional analysis is easily beat by irrational investment even on multi-year timescales these days.

The stock market is not the economy, as we can tell today.

I do think “things are different” in many ways, in the sense that it’s impossible to ignore the interventions the Fed has taken to blow up their balance sheet to $7T and will likely reach $10T by end of year. The speed and size is unprecedented.

Unfortunately I think Millennials will be the ones that have to deal with the massive debt we are in as a country and unwinding of the Fed’s massive balance sheet, which will play out 10-20 years from now.
