You are obviously not used to dealing with thermal expansion in other designs, but this has been done time and again before so from an engineering point of view this is mostly a solved problem and not a 'big deal'.

For instance, you could have periodic sleeves that can slide over one another so you don't end up with the expansion on the final endpoints accumulated, the trajectory could be adjusted to allow for translation of some end-to-end expansion into a sideways expansion (much like what you see in long runs of heating tubing where they throw in the occasional U or loop to make sure the tubing stays put on the longer stretches) and so on.

There are a lot of really hard technical challenges involved in the hyper loop concept, I'm not sure why you'd focus on the thermal expansion as the major one, it's trivial in comparison to some of the others.

Btw, in railroads (that other long distance transportation method) the expansion is dealt with by putting a small gap between two adjacent rails. That's obviously not possible with the hyper loop as it is currently envisioned but I think that the answer is in there: don't allow the differences to accumulate over long stretches. We already have plenty of long pipelines, this one is just a big bigger in circumference.
Your comment does not compute: SeanDav collects women's phone numbers but does not actually call them.
Or, in Apple keynote style: "Richard Rhodes has introduced the best account of the development of the atomic bomb, a top-notch biography of the greatest minds of the 20th century, and a terrific summary of early-mid 20th century physics. These are NOT three separate books--this is one book, and he's calling it The Making of the Atomic Bomb."
I feel like I remember seeing a steampunk variant of this idea in some animation/comic (maybe in the Flight series or Bolt City?)

Scene: ten miles over a major metropolitan city, an ICBM is racing in. Seconds later the nose cone is jettisoned and a cluster of small cones begin pouring out. Little grid fins pop out and they scatter out like dandylion seeds to the wind. Zooming on one, we watch it hurtle towards an enormous skyscraper. The cone's nose begins blinking from green to red, blinking faster as it approaches its target. Screaming closer and closer, we see the tower suddenly open a panel showing a large tank and the cone slams into it with an enormous splash. As it settles a platform gently captures it and raises it up to a crew of people with mail carts ready to distribute the packages.
True story. I could not tolerate most programming without consistent conventions to guide me. Pretty much every programming language has had a meta-language of convention that went with it, to support learning and readability.
> Because you can't go below zero. There's a floor to how much you can lose, and it's "everything you've put in", not "everything plus additional debt".

If you're leveraged, you are borrowing money, which means you can lose more than you put in as you could lose the money you borrowed and thus would owe on the debt. Further, if you are shorting bitcoin for instance, there is no floor.
I see your point, and I repeat I'm not arguing with you, I don't have the knowledge you clearly do, but onion layer security is I guess useful when mistakes are made -

> Lets say you create a encrypted LUKS partition with a 32 character password. Would it be [...]

Quite so, but if someone does a booboo and uses a 3 character password for one of them (well, imagine more sophisticated form of such a mistake) then the extra layers become valuable.

I guess it's about guarding against dumbness or accidents rather than correctly implemented best practice.
The article mentions that antimatter is explicitly excluded to keep the diagram/model simpler. It sounded like it would be basically another whole copy of the same shape, bit I have no idea how it would be connected, which would be interesting!
This used to be common in parts of Europe as well. There is a book called From Poison Sweets to Counterfeit Coffee—The Dark History of the Food Cheats, from the food journalist Bee Wilson [1], which tells (among many other things) a lot of stories about arsenic poisonings in 19th century London, caused by the usage of certain red dyes in food. The saying that certain regulations are written in blood comes from these kinds of stories.

Extreme acceleration and extreme heat from extreme velocity in the lower atmosphere.

Problems that could be solved but at what cost? The marketing for this is the reduced cost --- which may or may not hold up in practical terms with real satellites that are usually more than a simple projectile.

In other words, the cost to engineer and build a satellite capable of withstanding the launch may exceed any savings.
Correct, garbage collector was added to PHP 5.3, prior to 5.3 PHP did only reference counting. PHP 5.3 was released in June of 2009.

Here is a series of articles that describes it in detail

I listened to this excerpt from a book by an Icelander who was captured and enslaved by Barbary raiders. Very interesting, would recommend.
Prioritization will depend on your goals, so it is hard to give specific advice. But I will say that defining your goals is the first step. Once you have those, you can figure out which tasks take you towards those goals most effectively, which tasks are blocking others, and prioritize accordingly.

FWIW, I split my tasks into three lists - Personal Tasks, Home/Property Maintenance (I live on a 40 acre hobby farm, so this adds up), and Work Tasks. Personal Tasks are driven by my goals to stay healthy and create artwork. Home/Property tasks are driven by my goals to increase food production at my home and improve our self-sustainability, and Work tasks follow my employer's goals.

Your goals likely won't match mine, but a similar breakdown might help.
A lot of this was common in the US and Europe a hundred years ago, but laws and changing culture have stopped it. Just look at snake oil, or the many other “remedies”. See, eg, “ Down and Out in Paris and London” by Orwell, where among many other things he talks about how the restaurant kitchens in early 1900s Paris were extremely gross and dangerous, but because the front of the restaurants were clean, the customers seemed happy.

“A customer orders, for example, a piece of toast. Somebody, pressed with work in a cellar deep underground, has to prepare it. How can he stop and say to himself, 'This toast is to be eaten—I must make it eatable'? All he knows is that it must look right and must be ready in three minutes. Some large drops of sweat fall from his forehead on to the toast. Why should he worry? Presently the toast falls among the filthy sawdust on the floor. Why trouble to make a new piece? It is much quicker to wipe the sawdust off. On the way upstairs the toast falls again, butter side down. Another wipe is all it needs. And so with everything.”

China is at an interesting point because they’ve developed economically so much in the last fifty years. Their culture and law enforcement hasn’t caught up yet while the internet has, so this is shared with us.
I've had something like this happen to me, albeit less serious: I was snowboarding, went over a jump poorly, and found myself totally disoriented as I careened through the air. Every single other the I'd found myself flying through the air flashed through my head at unbelievable speed, in an attempt to search for some past experience to leverage wtf I should do. Ultimately I found nothing, made peace with the fact that I was going to slam into the ground, and promptly did so.
Here are a few links that give slightly more information:

Have anyone evaluated Matomo vs Countly vs PostHog?
I am going to disclaim this, by stating upfront that I have no fundraising experience. I think what I would do if I were in your shoes, would be to squeeze the roadmap, I do not think anyone would be willing to put down 500k and then wait 4/6 months before the product is even launched.

I would look for a launch in the next month.

To draw on a successful example I seem to remember twitch raised a similar sized seed, but launched 3 products in the first year before launching twitch.
I am becoming increasingly skeptical whenever I read claims of transphobia being made. To be sure, there are those who seek to undermine the rights of transsexuals, and who seek to pass legislation accordingly. But at the same time I see issues like this one, or the one with J. K. Rowling, and it does not seem so clear cut at the least, and at the worst is bad faith sanctimony.
Is it showing the date in local Australian time, or translating for your time zone?
No, it's actually the opposite - it has very rigid build rules with rigid inputs and outputs so the toolchain can reason about dependencies and it doesn't really allow adding arbitrary execution in the BUILD files to prevent code messing up caching and remote builds.

It was build to solve a problem of building software at scale across multiple languages, platforms in a single monorepo. And it's great at that. It becomes limiting as your use-case steps away from this "monorepo, across languages" approach.
I find comments like this confusing. It seems that you agree with leftists that equality is important value.

But then you say:

> all the "tax the rich" regulations in the end mean "tax those who cannot escape taxation"

Why is avoiding taxes different than any other moral problem? Why cannot you say, "putting conmen in prison" in the end means "smart conmen will avoid prison". It's this moral defeatism that gets me.

Sure, there will be people who do immoral deeds and avoid being caught, but how are we better off by not trying to catch anyone?

It's even in the open, that the large corporations pay little taxes, everybody is a witness to that. You (as a society) can change that system if you want.
This is very true. You get the same thing with people who live in Japan for a bit and declare that the political climate there is so much better. Eh, no, you just can't read the newspapers.

What if Google also stopped routing emails to Australia? All ads advertising Australian products around the world?

I wonder how hard they're willing to play here.
> If an employer over-rewards a group of employees, it's at the expensive of the employer, not the other employees.

I don't know where you got this idea...

Most places I've worked have at the very least a vague definition of a budget for talent acquisition and retention

If you give person X more of a bonus, there's less to go around for everyone.

It's not that complicated.
So if I understand this design doc correctly, a Linux program invokes SYSCALL to call mmap(). The Fuchsia kernel throws an exception to signal a separate starnix userspace process which peeks into the Linux process to read its arguments and then it issues even more SYSCALLs indirectly via the Fuschia DLL in order to ask the kernel to manipulate the PML4T page table radix trie which controls the Linux process memory, before finally issuing yet another SYSCALL to signal it to resume running.

Since the overhead of each SYSCALL is ~1000 cycles and that this overhead just keeps getting worse thanks to things like Spectre, I'd say that's a real high performance operating system you've got there Google. History shows us that developers never choose microkernels. The only reason people use the things is because big corporations force us to. Like how Intel preinstalled MINIX on its chips without the consent of its customers. Where are the early authentic Google values that technology should be simple fast and stay out of the way? Your o/s is bad and you should feel bad for all the reasons Linus explained to Tannenbaum back in 1992.

If Google was smart they would support something people love which makes perfect technical sense, like Cosmopolitan, which enables normal POSIX programs to boot as unikernels that needn't incur any syscall overhead at all. The Actually Portable Executable format is also a valid disk image that can boot on bare metal in Google's Cloud. This is perfect for our brave new world of cloud services where instances only really need sockets to talk to network services like bigtable and therefore don't care about the overhead of a timesharing system. Google created this new world, yet it fails to understand its own creation if we consider how Fushcia is dragging us into the past by resurrecting designs that were too slow even during the days where multitenancy on a single machine mattered. See https://github.com/jart/cosmopolitan and https://github.com/jart/cosmopolitan/issues/20#issuecomment-... to learn more.
I'm guessing it's because most people spend very nearly their entire careers nestled comfortably within a single programming language family. So one maybe gets used to the idea that one should be able to decipher an unfamiliar programming language just by reading it carefully, without needing to do any background study first.

It's most pronounced with lisp and ml-style languages, but I've also seen Java lifers bounce off of things as innocuous as Python's list comprehensions.

If it is the same as the glucagon hormone mentioned by the grandparent comment, it SHOULD be 'natural' and have no side effects.

But just look at reproductive hormone treatments (the pill) to see how things like this can go wrong (serious mental side effects; my sister struggled with seasonal depression for half her life, turns out it was just the pill. My girlfriend developed suicidal ideation from the Mirena coil. They stopped a research in male anticonception medication because of the mood swings).
Who are you asking this question? Let's stick to the facts of the investigation, please, and not cast about beyond what we know.

It could be related to the fact that Spring is starting in the Northern Hemisphere, and thus, the body reacts to the increased amount of polen in the air.

I'm allergic, so it's normal for me to suffer those symptoms every Spring.

I’m really going for a purposeful tool here that you can use to get what you want. Something a bit more than SFXR but a lot less than Reaktor.
Why not take some of the discrete components out and introduce another cpu to handle both video and sound? it would make the design much simpler and programming easier overall.

Also, why not use a more capable cpu with more embedded ram? These things are very cheap nowadays.
How's this different from QuantConnect and Quantopian? Also, people are not very open about their strategies.
isn't anybody else creeped out by this??
Yep, that's the problem, it doesn't know. But for a good product it should know, these things should be possible to integrate trivially with the result being both reliable and automated.
It's not really a free market that's why these tech companies all have anti trust investigations. This is censorship. It's just censorship lots of us agree with.
> I think we probably broadly agree

I think we do - like you said, anyone without an iron in the fire isn't going to make it, and VW at least have that going for them (likewise Porsche which VW own).
Private market censorship is legal w.r.t. the first amendment. If it's good for society is a separate question.

Why does anyone ever open up a store in the real world? I mean there's already Macy's, Safeway, Cartier, Aldi's, practically any type of store you want, you can already find. So why open up a new store?
It's too awesome in scale and depth to be adapted for a three hour film or "Sci-Fi Miniseries". I love the book, it is my all time favorite.

What I would like to see, however, would be small focused shorts; that could go over well I think (sort of how Neill Blomkamp and Jackson did those Halo shorts).
To me, the only reason to hate Flash is that Adobe has continued to market it as a platform for things it's just not appropriate for.

A VM is not appropriate for banner ads.

A VM is not appropriate for a restaurant menu.

A VM is appropriate for a complex RIA such as http://www.audiotool.com .

I think there would be a lot less hate for Flash if Macromedia and later Adobe had stuck to promoting it as an RIA environment and not as a solution to everything else.
HackerNews is almost omniscient. I am in the Apple Store right now, waiting for a genius to talk to me to replace my first gen Air drive. I did not know I couldn't get my drive. Now I can at least prepare for the argument and try to stay civil.
The pandering-but-truthful answer is that I once started the world's most trivial software project out of a desire to afford video games without deferring student loan repayment.

On a more practical note, it turned out that the software project had one really, really useful facet: it sat on top of (and allowed) a nearly infinite variety of easily templatable content creation tasks, for which the Internet's existing answers were uninspiring to say the least. At the time I was not exactly a naive babe in the woods about SEO, and I knew that would be helpful, but I had no clue the extent of how helpful. I don't know if I would have failed but for that marketing hook, but it was huge for me in my early days and still represents a major chunk of my business.
this article is ridiculous. He makes blanket claims based on the performance of a very specialized application. For many / most applications, memory is so cheap that you CAN effectively ignore VM. Where some thought about the relative latency of memory is useful though is in parallel applications on NUMA hardware.
he believes the cost of switching operating systems escalates with time

Where's the evidence for that?

Desktop OS behavior has been converging for years. Linux gradually gets more and more features that were formerly restricted to proprietary systems (e.g. iPod compatibility). Emulators have gotten better. The hardware has converged: Everything runs on Intel now. The OS has converged: Everything runs with Unix underneath now. The browsers have converged: there's Webkit browsers for Mac, and Webkit browsers for Linux.

What makes it harder to move from Mac to Linux (or vice versa) than it was, say, three years ago, or five years ago?

What I really don't understand is how you can simultaneously argue that Apple isn't going to continue introducing new Mac OS features and that Mac OS is going to get increasingly hard to migrate away from. Stationary targets are easy to hit. It's moving targets that are difficult to track.
In his video interview for Reddit, I thought Rowe came across as exceedingly genuine and self-aware of his position as actor and television personality, rather than worker. He also expounds on the things he has to say in the TED talk in a way that made me think the "lesson" was not just tacked on, but rather something he has spent a lot of time thinking about.

There are multiple communities of 'creative coders' who already work with this paradigm using tools like vvvv[0], MaxMSP[1], PureData[2] & others.

Closer(ish) to home we have QuartzComposer[3] available for OSX.

I like all of these tools but can't help feeling I'd be more effective if I could just get at the underlying code half the time (in cases where that's not an option).

They are all over any major story on reddit. And the HBGary release proved this to be actively implemented fact.

The fact that a significant amount of Reddit traffic comes from Eglin AFB, indicates that this may be where these MISO agents are based.
Again, you have to understand that Sunstein is an academic. When he says "the right thing to do" he means "what an economically rational actor" would do, not "what the government thinks an economically rational actor would do." The step from the former to the latter is the difference between academia and reality. The fact that the latter might make certain ideas unworkable does not mean that its sinister to consider the former in an academic context.

Important VIM tip that cheatsheets never mention for some reason: text objects. First, remember these two things: a for a, and i for 'inner'. 'daw' deletes a word under the cursor. 'diw' deletes the contents of a word (the 'inner' of a word) under the cursor.

What? How is that useful?

'das' deletes a sentence under the cursor. 'dap' deletes a paragraph under the cursor.

'da{' deletes the block of text that's currently surrounded by braces. 'ci(' deletes the inner content that's surrounded by parentheses and puts you in insert mode. 'gqap' reformats the contents of the paragraph under the cursor ('gqip' will end up leaving your cursor at the beginning of the paragraph instead of the end.)
The DoD doesn't exactly promote a hacker culture in the civilian roles; however, depending on branch of service (e.g most likely not marines) and role (officers and above), there is latitude for creativity.

Of course, anyone who has worked the civilian side of DoD knows how bureaucratic it is, and I think pg is right to say that if DoD likes it, it's probably not a great sign. For instance, you can't submit invoices (you have to use a convoluted procurement application and enter it through a very 90s looking app). There are paperwork mandated by Congress and administrative agencies (GSA). And let's consider the Goliath that is DFAS. They use Oracle. And Oracle Forms.
Agreed, there are certainly exceptions to the rule but I don't think anyone would put the level of Java's "hacker acceptance factor" anywhere near Python or Ruby or the like.
I am shocked that "value" or "value add" didn't appear on this list.
