The worst thing about the Hyperloop concept is how it takes different smart people with slightly different assumptions about what is being described, how it should work, and how it does work in the fields they are familiar with or experts in and the other fields they are only conversant in, and turns those people into rabid defenders of their own calculations that somehow lose the ability to reassess where mistakes might have been made. I'm not sure how or why this happens, because as far as I know none of this is theoretical science, it's just a matter of applying the principles accurately (which seems to be the sticking point). For example, here's a whole playlist of people arguing over the physics of it, which does devolve into name-calling at points.[1] There appears to be good science involved in the assessments though, but could be said for the most part about both parties. The interesting parts are where people step outside their areas of expertise and their unfamiliarity with the application of the principles causes mistakes.

The preprogrammed difficulty bomb is not to stop people who want to intentional stay on the old fork. It's to stop the old fork winning consensus by default due to people who don't actively upgrade.

Pushing through protocol changes could be hard if everyone who takes the default action of doing nothing is counted as a vote against any protocol change. I think we see this with bitcoin where change is very conservative and slow because any change has to gain enough support to be actively upgraded by a majority.

The difficulty bomb just means that if there is ever disagreement about a protocol change, everyone will have to actively choose a side rather than the 'no' side getting all the non-active default votes.

It basically just means that changes can be done faster.

The amount of work that goes into creating and selling a brand, running the actual business (selling, implementing, supporting), on top G&A, is way more than people realize.

On top of that, the amount of work that goes into raising money, preparing for IPO, etc. is also quite a lot.

That's before you get into building the actual product, developing the roadmap, working with product marketing, R&D, etc.

I run this issue especially when building software for parts of the business that aren't product - engineers are so condescending it's remarkable.
The incompetence is mindblowing. Could this be a good argument for software engineers to get their professional license?
AI is just a tool, a way to automate making more kinds of decisions. The decisions are not better or inherently more right by virtue of taking a human out of the loop. In fact, they're usually worse, because humans are intelligent for real and computers are not.

But the decisions are automated, and that makes more things possible. And sometimes you need to deal with the effects of automation.

Nobody could reasonably declare an AI "free from biases", but you can work on particular aspects. Here's an example: Meetup de-biases their recommender system so that it doesn't automatically recommend knitting instead of coding meetups if you are a woman. [1]

Yes, in the data, there are relatively more women going to knitting meetups and fewer going to coding meetups, but it doesn't have to use that data or its correlates to make predictions. In fact, it shouldn't. If you do like knitting, it can still learn that from your actual personal preferences and not infer it bluntly from your gender.

Some minor pedantry that winds me up a bit, and that I thought I'd try to correct:

> Note that one of the co-authors of this paper, Amit, is the author of https://www.tockos.org/

The definite article "the" precludes the existence of other authors, who (from personal experience) can get wound up by language like this.

You may have meant "author of the web site", in which case I have no opinion, but if you meant "author of the project" I'd totally use the indefinite article "an".

Also all of the work is very interesting and people should read it.
Xidnaf has a good video introducing AAVE from a linguistics perspective.

https://www.youtube.com/watch?v=pkzVOXKXfQk
Yeah, he is really quite good at this. (I wonder if it came naturally to him, or if it's just a matter of practicing very regularly for like 20 years?)

I wish he would give Elon Musk some mentoring on how to communicate with a technical audience. Or just a regular audience, I guess.

Sure, and many rules of AAVE are more consistent.

For instance take the following words in standard English:

* yourself
* myself
* ourselves
* himself
* itself

One of these things is not like the other! All of these take the form of possive + "self," except "himself." And sure enough, in AAVE we have "hisself" instead. A more logical, consistent replacement.

> It evolved out of necessity in the absence of education.

Citation needed.

My main exposure to black American English is through popular music (hip hop / rap), so take what I'm saying with a grain of salt, but there has been so much change in the vocabulary just in the 20 years that I have been exposed to it that, IMO, there's no way that it can be due to anything other than deliberate linguistic experimentation/innovation. You might be familiar with somebody who experimented and innovated with English in the same way: Shakespeare [1].

There is a very big aspect that people overlook in this conversation.

There is what is known as the "dialect of power" and in the US that is Standard American English.

It's not necessarily "wrong" to speak AAVE but in doing so, you will disqualify yourself from opportunities that could otherwise be open to you based on your education and/or experience.

If someone calls you to schedule a job interview and you don't sound the way you're expected to sound when you speak, they'll mentally cross you off of the short list before you ever cross the threshold of their place of business.

As an African American man, I'll admit that when I'm exclusively in the presence of other black people, I'll code switch and speak in a way that I never would at work or in mixed company.

I have a very Anglicized name and I speak Standard American English. As a result of that, people who haven't previously met me in person are sometimes surprised to learn that I'm not a white guy.

Being inclusive is a worthy goal but I think that education should stress the importance of speaking Standard American English because it's necessary to do so if one wants to be successful in this society.

When groups of people separate (for whatever reason, including social oppression reasons) language drift can happen. It doesn't have to be lack of education that causes language drift.

I think you are throwing the baby out with the bath water. You don't have to invalidate the language used by millions of people TODAY (e.g. by calling it a "so-called" language) in order to question why this language emerged. In fact I think that your comment perpetuates a harmful idea that the language that a certain oppressed group uses is not legitimate and broken.
You can't make a valid recursive tree without a pre-image attack against SHA1. However `git` doesn't actually verify the SHA1s when it does most commands. If you make a recursive tree and try `git status` it will segfault because the directory walking gets stuck in infinite recursion.

The paper talks about that, calling it a distinct language is what the Oakland school board did, and this spurred a semantical debate that devolved into exactly what you mentioned, while being a red herring in and of itself.

This paper lends credence to it being a valid dialect.

Yes, your thoughts could be said of an absence of education in Appalachia too. That doesn't lessen the distinctiveness and perpetuity and acknowledgement of the dialect.
The problem tends to stem from misplaced feedback, not intentional badness. In this case the scenario is set by copy-pasting the dev cycle of previous games onto a new one. The game gets designed from the surface(marketing, and specifically marketing artifacts like the Gex character and a pitch that dictates the design) inwards and so ends up with huge gaps in what it wants to do versus what it actually does, and tons of stuff that gets thrown out as unusable. And then new technology gets in the way.

I am actually finishing up a project that went very similarly, just at a smaller scope.

If you see from my discussions, many in the community (not the Rust designers) seem to be unaware, willing or not, of all the great work that came before Rust.

Rust is making a great progress infecting other languages with the idea of having affine types for resource management and concurrency is possible, just that the ergonomics still need some fine tuning.

No need to glace over the ideas of other strong type systems programming languages.

Axial compressors aren't the only compressor design. Rotary vane compressors have no problem with those pressures.

The internal pressure was chosen explicitly because it was easy to maintain with simple, single stage mechanical vacuum pumps (see Figure 13 on page 22). Heck, the first result on Amazon for "vacuum pump" goes down to 5 Pa. https://www.amazon.com/dp/B012CFTYX4/

Compare the Hyperloop to true "vacuum train" designs, which need to run at 1/1,000,000th of an atmosphere to mitigate sonic booms (an alternate way to get around the Kantrowitz limit). This requires multi-stage pumping with mechanical roughing, followed by turbomolecular pumps and cryopumping. That 1000x harder vacuum takes 1000x as much pumping power (not because the differential pressure is meaningfully different, but because you expel 1000x less air per stroke).
Ok, but why? Why are people willing to pay that much for it?

So when some people think of AAVE speakers as incorrect, it is because they don't use the right wrong way to talk. Linguistics is a weird field.
No, it's not. It's just erroneous here; AAVE has an internally consistent grammar just as any other language does. I know quite a few people who code-shift between AAVE and standard American English, just as I do between that and the (admittedly somewhat less different) dialect of my youth.

The remainder of Overtonwindow's comment flows from that error and one other, which is to assume that AAVE is a "degraded" form of standard American English. It is not; it has old and many-branched roots of its own, only some of which lie within American English.

But who knows? Perhaps Overtonwindow is a more accomplished historical linguist than those on whose statements I here rely.

Note that the headline is saying that the Yemen cholera epidemic is the worst in recorded history by number of cases. I assume rehydration salts are available and being used by the simple fact that the case fatality rate is fairly low-- 0.26%. Seasonal flu, by comparison, has a CFR of ~0.1%.

Cholera before rehydration salts could be quite deadly-- as recently as 1974, Yemen reported a CFR of 16.67%: http://apps.who.int/gho/data/node.main.177

(Some of the numbers reported in that table are oddly high-- Vietnam reported a CFR of 100% in 1954, then 4.32% ten years later. They're not showing the denominator, so the hundred percent figure could be just from a handful of cases. Reminds me of Ebola, which was thought to be a death sentence from the awful CFRs reported from small outbreaks, but brought down to a "mere" 25% with aggressive treatment in Western hospitals.)

> You're just describing a usual vacuum pump

Scaling is hard. The largest vacuum chamber we've built is a fraction of the size of the proposed Hyperloop. It was a very, very hard problem [1]. It's expensive, sucks up loads and loads of power and needs lots of thermal management, structural reinforcement and vacuum-off maintenance.

> Keep in mind that the absolute pressure difference is far less for Hyperloop than for a typical natural gas pipeline

Pipes are pressurized from the inside. See my comment from elsewhere in the thread on why vacuums are different [2].

All this said, I generally agree with you. I don't think building a giant vacuum is beyond current technological capability. I do think building one structurally sound and thermal-expansionwise stable enough to carry passengers at high speeds is.

The PC shareware version of this game was the very first thing I ever downloaded from the internet back in 1995. I never got the audio to work. With my Sound Blaster 16 card it would always produce the "data noise" that you would hear if you were to play back a data track in a CD player.

This is one of those unanswered questions in my computing career. Did anyone else play the PC version and if so, did you also have problems getting the sound to work in the shareware demo? Does anyone have any ideas as to what could have caused this problem? Was it just not tested?

If I never do get an answer, one day when I have time, I hope to set up a test environment, find that old shareware demo and try to reverse that part of the code to see what it is doing.
They'll need to strongarm BNSF, which is trying to charge egregious fees for passage rights on their railways. It really gets my goat that the government is the one that gave the railways to BNSF for basically free in the first place.
Sure, but lots of people code switch. As a southern white guy, I also don't speak on interviews the same way I do to my friends. Even around other southerns, you want to "turn it down" in a professional setting.

I don't think there's any danger of English teachers not pushing standard American English. Mastering it does open doors. But I think we should also learn about other dialects, because in learning about them we learn more about language.

I also think reducing the stigma of certain dialects is a good thing.

As it relates to the article, the school board basically sanctioned speaking this dialect. My thought was that, this action is increasing the obstacles to overcome: textbooks are written in "white" english and the teachers speak that way, but they're promoting that it's ok to not read, write, or understand the dialect, furthering the divide between the communities.
Not only that, we are considered the best non-native English speakers of the world, so even if you aren't keen on learning Dutch (boo!) you'll manage pretty easily :)
