+1 for pointing out that Boeing has significant revenue from military contracts. The Seattle Times analysis seems not to take that into account, but rather focuses on purely commercial aspects.

New passenger planes are extraordinarily expensive to develop, and only 2-3 corporations in the entire world are capable of it.

Boeing traditionally has introduced new models with advantageous features, then continued selling them for decades, gradually rolling out slightly modernized versions that the airlines can purchase to refresh their fleets without completely retooling to support a newer model (retraining mechanics, purchasing new parts, etc.).

The article argues that Boeing will take ~5 years to break even. That actually sounds pretty good. I would give them 10-15 years.

The fact that only one Boeing person seems to have been consulted for this article suggests that it's mostly speculation by outsiders and former insiders, and not a realistic analysis based on comprehensive data. If Boeing's betting on military contracts to keep it afloat while the more profitable 787-9 and -10 models come online, so what? Sounds like a reasonable thing for this kind of manufacturer.
Here's the original MIT research group. Consider that this was done 17 years ago, so it's possible that relative performance differences are very different:

https://pdos.csail.mit.edu/exo.html

The speedup they observed was because they could bypass all the layers of the OS and implement abstractions specialized to their particular use-case, making use of information that is available to the application but not to the kernel when deciding how to allocate resources. For example, Cheetah stored preformatted IP packets on disk, which would be sent straight out to the NIC along with the file contents from the filesystem cache. There was no need for the overhead of a TCP/IP stack, no need for buffer copies between kernel and user mode, no need for scheduler overhead as the process is put on the wait queue while waiting for the filesystem, no need for kernel-mode context switches.

I could imagine several similar cases with modern apps, particularly as the NUMA penalty has grown and we've gotten hardware technologies like RDMA. Imagine a Node.js implementation with a locality-aware scheduler, for example: instead of running whichever closure is attached to the file descriptor that epoll happens to return, it preferentially executes the closure that was most recently enqueued, on the theory that all of its context is likely to be hot in cache. Or imagine memcached with full control over the TLB, so that you could lock certain entries (eg. active session objects) into the TLB and never page fault on them.
Good point. In this case it is essentially the same as using a known algorithm with unknown parameters.

Either way, this increases the space of possible upscaled images dramatically, which makes it a lot harder (if not impossible) to produce result of the demonstrated quality.
One of the issues is, once you cross a cost threshold, it's cheaper to automate. We're automating all kinds of things which used to be pretty hard (harvesting), translating, (sports) reporting, and even burger flipping, for the price point.
As the poster of this piece, I can suggest a simple explanation: upon reading one of the first pieces, I searched the web for more information. Upon finding an interesting followup, I posted it here.

Ask HN: Low marks vs. Side projects?

To be fair, most of those accidents seem to be pilot error of one sort or another, perhaps more a critique of airline competency in that part of the world, rather than the aircraft itself.

Anyone would agree the NYC subway system is mission-critical (without it, NYC would slow down to a crawl), yet its technology infrastructure has obviously been neglected for decades, due to lack of money, lousy management, corruption, or a combination of all these factors.

It is impossible for a company that makes money by saying no to it's customers to become a beloved brand. In healthcare we are constantly talking about disruptive innovation and the usual suspects that get mentioned in the news are genomics, big-data, wearables, etc. However, I believe that effectively exposing certain parts of the healthcare industry to market forces is a highly effective way to empower the consumer and further disrupt the market. Insurance companies are the obvious target here. We have moved from catastrophic coverage to a coverage catastrophe, where even the smallest claims are submitted to insurers. This has created a middleman that is ineffective, expensive, and almost universally terrible at customer service.

You pretty much have to give equity for that kind of risk, because the interest on bonds you could sell would not be commensurate with the projected cashflow.

But "betting the company" doesn't mean in this case that the company would disappear. It would just go bankrupt. That is a scary word, but in a case of Boeing, (some) equity would just be transferred from shareholders to creditors; operations would not be affected.
This could make for an incredible movie plot. Humans spend all this time studying climate change and debating about it, only to find out that we were staring the result of it right in the face the whole time: Venus. We discover that the origin of man is not Earth. Rather, we were colonized here by our great ancestors, forgotten in time. Ancestors that came from Venus. They left after destroying the planet. And now, here we are on Earth, repeating history.
Abstractions are important as they reduce complexity, and simplify operations.

The foundation of computing is based off abstraction - using layers and interfaces to hide complexity, so developers can focus on higher-order problems.

This article argues against abstractions citing security, performance and cost. But time and again it has been shown that most costly component in software is human time - and simplifying the underlying architecture is worth the trade-offs
Sounds like a self-inflicted mental anguish to me then.

Historically, in the 20th century, Boeing's only profitable planes were the 727 and the 747. See "21st Century Jet", which is about the 777. (The book, not the PBS special.)
And those designs live for quite a long time, the brand new USAF tankers which will come into service in 2017 are based on the 767.

https://en.wikipedia.org/wiki/Boeing_KC-46_Pegasus

Those tankers however will use new technologies from other projects like the cockpit displays and avionics from the 787.

And these ones will slowly replace the USAF current tankers the KC-135 which are based on the Boeing 367 (which turned into the 707 for it's commercial release) which has been flying since the mid 50's.

People underestimate the life span of most aircraft designs, at least of the good ones if the design is superior it's practically timeless.

The US is still building new U-2's because there's nothing comparable to it still.

You definitely can use online learning with logistic regression. There are also ways to get it to work with random forests / boosted trees.
I'm no stranger to insults, I can take what I can dish, but I also think this is true: everybody can argue their point without being personally insulting (some, like me, take getting hellbanned a bunch of times, others just do it straight away), but not everybody can look past the insults and focus on the points made. So a free-for-all this excludes people who simply don't like being insulted while gaining nothing when it comes to the content of the discussion, the arguments.

FWIW, I'm not a huge fan of downvotes, and I don't even like things being ranked by upvotes. But the rough spirit of focusing on substance and backing up claims, that I like.
An additional issue with supersonic is it doesn't save you time waiting in line at the airport or driving to and from. So the net comparison isn't 3.5 hours vs 7 hours of flight time (Concorde vs 747, New York to London); it's more like 6.5 hours vs 10 hours of total cab + airport + flight time. Either way, you're probably tired from the trip and won't be particularly productive, so why not pay less money for a more comfortable seat in a bigger, slower jet?

(While I never flew Concorde, I did babysit one in a museum. There isn't a single seat that isn't cramped -- even in the cockpit.)
It is one thing to have the government get access to software, and quite another to have truly open source software. Does the entire Chinese population have access to the source? I seriously doubt it.
In terms of passenger capacity and range, the CS300 falls somewhere in between the current 737-700 and 737-800, or current A319 and A320.

The CS100 is more of a 717/E-190 competitor, but the CS300 is absolutely aimed at the types of roles 737s and A319s/A320s are currently deployed in.

Hmmmm. Users spend far more time in apps on mobile, bit from what I've seen it is limited to a few big hits (Facebook, email, messenger apps, maybe games). I think if you are looking to be discovered, the web has no competition.

If, however, you are the kind of company who can provide utility often, and want to build loyalty, an app is great. But if it is just news stories, it's not much utility.
Now, correct me if I'm wrong, but haven't we essentially got the exact opposite direction and strengthened the abstractions separating hardware and apps? I would assume elimination of abstractions would reduce portability unless suddenly the market moved to a unified hardware architecture, while we've gone the other way; we have numerous platforms of hardware AND software, and code is generally more portable than ever before due to the use of standardized languages and APIs.

Nothing stops you taking the advantage of both.

I think the main question is why we feel a need to impose a single one-size-fits-all universal unit set onto disparate domains with different ideas of what properties make a unit desirable. There are domains where base-10 units are a good fit, and other domains where base-12 units are a good fit, and I don't see why we need to try to force one set of units to serve both.
So you got to the end solution of... uninstalling fail2ban to fix it? You didn't bother to check WHY it was maxing out the cpu?

Glad you got the issue resolved though and didn't fork over the $10 because you would've just run into the same issue in the future if you didn't get to the root cause of it (misconfigured Apache).

Absolutely. For lossless compression you just need to encode the difference between the predicted pixels and the actual pixels. Which hopefully has a lot of zeros, making it easier to compress. For lossy compression, you just throw away some or all of the difference info.

The biggest issue is speed. This doesn't look very fast to encode or decode. That's the biggest issue with new image compression algorithms, and makes it nonviable for most purposes.

It's really, really easy to misconfigure mod_proxy and set yourself up as an open proxy. The ProxyRequests directive sounds like it should be needed for any sort of proxying, but is only really needed if you're allowing your apache instance to act as a forward proxy, not as a reverse proxy. For reverse proxying, which is what you want most of the time, you really want ProxyPass and ProxyPassReverse .

No, the markups are still opaque and vary on an item-by-item basis.

Here's an example (from $5.99 to $7.39 plus a delivery fee. Still a really poor deal:) http://i.imgur.com/VwWk44h.png (To be clear, this picture is from their own site, because the item in question has a price label. Most things don't let you see the store price.)
"The other problem, as you can see from the videos, is that you're going to get some water on your face, clothes, and the table. That's the sacrifice you make for getting rid of water bottles from your life."

Of course, if you're concerned about disposable water bottles ending up in landfills, you could just use a conventional reusable water bottle (available in stores everywhere!).

I don't understand how you could carry around an edible water bottle without at least some kind of plastic wrapper to keep it clean. If so, the edible water bottle sounds less eco-friendly than a conventional reusable water bottle.

My experience with a malconfigured server interfacing Exchange is that Exchanges pretends everything is ok while receiving (with a 250 response at the end), and may sometimes notify its user (with a bounce message) while sending, but may also not.

It sounded as if they have mapped all of the connections between neurons in previous work. Which suggests these connections are genetic rather than learned, and the same in every individual worm. While that makes studying them much easier, I find it surprising. I suppose that's how innate abilities are conferred on the next generation even in humans where many connections will indeed be individually learned/constructed. Very interesting.

The paper says to move the abstractions, not eliminate them.

> It is important to note that we favor abstractions but they should be implemented outside the operating system so that applications can select among a myriad of implementations or if necessary roll their own 

For example, if my software doesn't like the OS's abstractions for networking, let me go find one that I do like and use it instead.
You had me up to "law". From the econ perspective, the "free market" does not include lobbying for particular laws. To define it as such is mockery of the term.

Assuming completely free property rights and contracts, unions would probably have almost no power. The power of unions stems from the fact that they are protected (e.g. you can't fire someone for joining a union) and the fact that the state ignores violent crime when unions commit it (but as far as I know that's not the issue here, I'm just mentioning for completeness).

I think that a legal system that is skewed towards labor is ok, for various reasons. But when you see wages pushed far beyond market wages, it's fair to ask if the system is too skewed.

So to answer your question, a person should not get whatever they can command by influencing the political system. Yes, both sides will try to do it, but in both cases the response should be to argue against them, and instead argue for impartial laws.

EDIT: the delay before the "reply" link becomes active is there for a reason. I'll respond to any reply that I consider to be based on a thorough reading of my post, and not a knee jerk reaction (for reference, the reply I'm referring to was written 4 minutes after my post).

This is one of the first papers introducing exokernels. The paper argues for breaking the shackles of OS abstraction and giving direct, (but mediated), control to the programs.

I like the idea, and am experimenting with it in my own OS. In the mainstream world, we see this paper's goals partially appearing with the people who give a network card directly to a server process in Linux.

If they said which architecture there were thinking about, I missed it. On x86 without IOMMU I can't think of any card I would trust. IOMMU implementation is so spotty I'm not sure I'd trust it either. There is a great deal to be said for keeping the device access locked away in the kernel where you know which features of the card you will use, and if it has a mode that lets it scribble elsewhere in memory, so aren't using it.
Because the main thrust of HTTPS at this point is regaining some privacy from snooping governmental organizations more than it is building a trust chain.

In lower-density areas, I think most supermarkets have found that online order + in-person pickup has been more successful, as a halfway solution that's much cheaper. A huge portion of their customers drive past one of their supermarkets on the way home from work anyway. Obviously this doesn't apply to people who don't drive to work in the first place, but about 90% of Americans do drive to work, so the numbers for that option are fairly favorable [1]. And in many zip codes the proportion approaches 100%. Walmart also recently rolled out an online-order / curbside pickup thing for groceries [2]. I'll be interested if any numbers emerge about how it's doing.

Of course the free market includes the rules that govern it. If you don't have rules, you don't have a market, just a rule of anarchic might-makes-right force.

If you're going to say "well, only property laws then," that's still laws! That's still a set of "this is how it should be" encoded into rules that we all have to agree to to take part in it!

It's just been, for so long, assumed that "screw the workers and don't let them fight back" is somehow "more free" that we treat that like a built-in thing, when really, that's just one way of doing it.

As for state-sanctioned, union-committed violent crime, oh please.

EDIT: Since you edited your remarks to include the last paragraph, I'll address that, too.

Why shouldn't people work to influence the political system in their favor? We all live here, we all have a role to play in the design and operation of the laws of our city/state/country. If enough people like strong worker protection laws, well, that's democracy, why shouldn't that stuff get encoded into law?

SECOND EDIT: Yeah, it only takes a minute or two to read what you're saying and respond to it. I saw a "reply" link right away, so if there's some extra delay built in, it didn't apply to me.
