> Quad engine? — why not 2?

Because thrust is proportional to mass flow times delta v. But power is proportional to mass flow times delta v squared. So the way to increase efficiency is to increase the mass flow as much as possible. A limiting factor is the prop/fan diameter <--> ground clearance. See the 737 MAX. But more prop/fans means more engines. And the complexity costs that come with that. Hence the popularity of two engine airliners.

I think there is a realization that with hybrid electric designs, you can have one engine + battery driving four prop/fans. My read on the depiction is an aircraft with one engine and four props.
When our government was much smaller, it committed genocide of American Indians and recognized slavery. Similar things can be said of some other countries with small governments. I'm not convinced that government corruption is much of a function of its size.
this only gets 67% accuracy, which is obviously an improvement, but it's still not close to sufficient accuracy to be useful. Historically a good test was how many "gods" or what not were invented in a translation.

E.g. at 67% accuracy a translation of Linear A would probably being meaningless

I've always felt US mathematics education is a case study in what happens when "lies for children" goes terribly wrong because the teachers never actually encounter a version of the field that isn't a lie.

My experience volunteering in an AP CS class makes me wonder if something similar is happening in K12 CS at the moment. The students knew by heart the JavaDoc for String.format but struggled with loops. The teacher also struggled with simple nested for loops. Kind of made me want to throw away the damn laptops and just spend some time solving problems on pencil and paper...

Quite fair, but not 100% certain.

Almost nobody really knows how developed is the state-of-the-art theory / applied technology in confidentials advances that the usual suspects may have already achieved. I.E. deepmind, openai, baidu, nsa, etc.

AGI could have already been achieved - even theoretically - somewhere, and like when Edison got to make work a light bulb, we're still using oil and not knowing anything about electricity, or light bulbs or energy distribution networks / infrastructure.

The actual current - new, mostly unimplemented yet - technology level.

I think this works fine for a lot of things.

The argument though is that can't run an EC2 (AMI) anywhere except AWS.

The advantage of Virtual box images or Docker/OCI images is that you can run them in multiple places (locally, AWS, GCP, Raspberry Pi, etc.) with consistent results.

I used to collect vinyl, but now I have a 3 year old who consumes most of the time I would otherwise devote to hobbies. She destroyed a couple Bob Dylan records early on, so all of my records are in hiding.

In the last few weeks, my girl and I have built several train tracks, built dozens of puzzles, read parts of about a hundred books, gone to see dinosaurs at our local Museum of Natural History and gone to watch planes take off at the airport. I play a lot of Monster and talk like a unicorn. Sometimes, I let one of her stuffed puppies pretend to drive. She’s potty training so we talk about poop and pee far more than I’m comfortable admitting. It’s a non stop laugh riot...
Yeah I have. I should re-evaluate. But other failure modes are sort of similarly random: bump into paint, get grease on it that stains it, lose it, rip it, or just honestly get bored of it. There definitely are items I own that are more timeless, but T shirts are something that I am hard on and get bored of easily. I am not a guy who wants to own five expensive polos, I want a bunch of different choices.
We make speaker wire and sell it primarily on Amazon, so I have some experience on the manufacturer side of UL/ETL marks. My advice is to never buy any product with an ETL mark. As an organization, they are way less stringent about enforcing the integrity of their mark. And I would also never buy anything at a low price tier that bears a UL mark, since it’s probably counterfeit. If you want quality, pay for it. When you pay for a brand which markets on quality at a higher price point, there’s a pretty
good chance you’re getting something legitimate. The reason is that it’s hard to compete at a higher price point, so honesty is probably the only reason a brand would willingly choose to scale that kind of a barrier.

No, not at all. But you have to find a partner that likes you for the height you are.

Are you saying that short people should lie about their height and hope they can convince someone who's met them to change their affectational preference? "Conversion therapy" doesn't work. If someone is only attracted to tall people, you can't change them.

So, you've stated that non-interference in the beliefs of people is a crucial element of the West. Either that applies to all states (vacuous) or you believe that states have some power to impose or not impose beliefs. Call it what you will, but those beliefs are enshrined in those states, whether they're universal, or not. They have them.

> The US Declaration of Independence and Constitution, for example.

Why do you believe that these documents which describe the US state are emblematic of the "west"?

> I haven't.

Awesome, so why does Rome circa 500 AD or the constitution have anything to do with the definition or character of the "west"?

For the sake of balance -- I do want to clarify that there is definitely land-grabbing happening on both sides of the aisle here. cri-containerd is a good example of the "Docker side" trying to land-grab cri-o's niche.

But again, I don't like all of this stupid politics over such trivial crap. It's ridiculously draining that I have to deal with people from the Docker project demanding me to apologise for things that Dan Walsh has said (or playing dumb when someone else from the SUSE makes a snide comment about several-year-old PRs that have burned out several of our engineers -- and then asking me to try to force them to apologise for it), as well as having to deal with the issues I outlined above. All of this back-and-forth has no benefit to anyone involved (or outside) and is just a waste of our collective lives. Posting this publicly probably won't help either, but I really don't know what the solution is other than to just quit and work on something else where we aren't just collectively accelerating human entropy.

To be frank, this is the main reason I've been working more with the LXC folks in recent years -- there are more interesting problems there and I don't have to deal with this crap. They also have really brilliant engineering, but that's not the main thing that attracted me to working with them.
Typing “git commit” when you reach a milestone costs nothing, and can save hours of trying to get back to a previous working state.
Based on recent experience in West Africa, it is rapidly looking like the internet traffic exchange and interconnection points for ISPs/mobile phone carriers/telecoms in that region is coalescing into two cities:

Lagos, Nigeria

Accra, Ghana

Both have the advantage of being on the ocean (where cable landing stations are built), major population centres, major business centres, and IT/networking/telecom education and training programs are run in the English language.

If you are a mid sized ISP in Accra it is still quite costly to buy transport circuits going "both directions" - to get a 10 or 100GbE circuit from Accra to Cape Town, to peer with ISPs and content sources there, and also to buy a 10 or 100GbE circuit from Accra to western europe (Paris, London) to meet major IXes there.

From what I've seen looking at BGP topology for a lot of these ISPs, Accra is sort of a suburb of London.

I only skimmed this, so perhaps there is more to this than meets the eye. But after reading I'm left with the question: Why does this need to be "neural"?

Given that there is a history of using classical NLP methods for sequence alignment / noisy channel decoding, I would've expected a more extensive discussion of how NNs might be able to overcome limitations of simpler methods.

But it seems the opposite is true--here they're using classical approaches to overcome limitations of their neural approach. The paper concludes by observing the "utmost importance of injecting prior linguistic knowledge" into the model. This "linguistic knowledge" is outlined in Section 3, and basically appears in the model as a regularization term based on a classical noisy channel / word alignment model. These regularization terms basically just encourage the neural network to behave like the classical models. And "neural" approach only performs marginally better than the (Berg-Kilpatrick & Klein 2011) paper they're comparing to, which takes a more classical combinatorial approach.

I don’t think US carriers can legally institute a no-children rule — i think this sort of policy would constitute age discrimination [0]. Not sure about other localities. Removing particularly disruptive/belligerent passengers seems to be fair game, but really that’s exceptional and doesn’t apply to most of the interactions being discussed here.

I don’t think anyone in this thread is saying that travelers should be entitled to shush other people’s children, which would be incredibly rude. You’re perfectly entitled to go through the intermediary of the airline, but I think polite engagement along the lines of what GP suggested would be a positive feature of society.

Another smart position from Warren (again, relating to her understanding of how the financial sector has an outsized prominence in our economy):

Devalue the (overvalued) US dollar:

https://www.nytimes.com/2019/06/16/opinion/elizabeth-warren-...

A common concern of vast swaths of middle America which appeals to both Trump voters and potential Warren voters is loss of industrial capacity / jobs / people / and stagnant wages. A huge cause of that (arguably orders of magnitude more than "free trade"/tariffs issues) is the imbalance of running the reserve currency and our dependance on capital inflows (bond market & wall street) to fund our trade deficit.

Either we run a super strong reserve currency and have a financialized economy, or we close the trade deficit. We can't have both. But choosing to have a large capital account surplus and huge trade deficit is making a choice who the winners and who the losers are. It would be nice if more policy debates centered on that dynamic.

This is amazing advise through and through. Ticks all the boxes. For many of us we spend so much time at work that we perceive our colleagues as friends. This is a fallacy. I left a job after 15 years and have maybe 1-2 real friends out of that time.

Drinking at company parties is so on point. If you need to drink a lot, make an appearance at the party and go drinking with trusted friends after.

Constructor validation is great, but it’s hard to tell from this example whether Book is meant to be a domain object (POJO) or a transfer object (JavaBean). It _looks_ like a transfer object (since CRUD was mentioned), but it’s unclear.

Either way, a more appropriate solution might be to stop using “stringly” types and use Value Objects for the properties on Book.

For example, “genre” should be either an Enum or some limited-value choice (perhaps from a database or external service). “Title” should be a Value Object class that constraints it to be of a certain length (at least 1 character). “Author” should be another limited-value choice (at least of type FullName, that has validity constraints). And “pageCount” should be a class that ensures it’s always >=1 (or maybe >=0 if that makes sense) and isn’t some outrageous value (granted, there’s always going to be some outlier that has an eBook that’s literally billions of pages, but that’s a biz decision that would be encoded in the PageCount class).

Using types instead of Strings would prevent confusion/mistakes by other users, and push the validation to the exact type, instead of making Book do all the work.

I think the main advantage that Tesla brings to this effort is the fact that they are creating everything in house. This means that they can concentrate on how the system works together as a whole and not have to fight about interfaces between disparate systems. Instead of having to learn how the entertainment center APIs work and writing code against that, they can just walk down the hall and talk to the people creating that code. I think that gives them a massive head start for this type of project. Plus, they have been writing automotive software for quite a while be well versed in it's peculiarities, not to mention the tooling they've likely created to help.

Editors which can always crash, because they are as stable as the least stable plugin? Formulas you can no longer edit because you do not have that specific formula editor installed? Completely closed and proprietary binary storage formats? Security as weak as the weakest app installed on your machine?

Granted, in the 1990's, COM was probably a pretty good thing -- it was very fast and efficient, at the expense of stability. Today, I'd prefer different tradeoff -- stable, secure and open; and if I have to wait 5 seconds for my auto-rendered markdown to get updated, it's OK, I can do so.

How to manage expectations.

That communication is incredibly important.

That the higher up the org chart someone is the busier they are. So what you spend 40 hours a week thinking about they might not spend 45 minutes thinking about. So over-communicate and remind them of important information about the project. Because they will forget lots of important details, and things that are glaringly obvious to you won't even show up on their radar.

Unfortunately some landlords/property managers have made declawing mandatory in their lease agreements, and many cat owners may be unaware of what the procedure actually entails.

In fact, the property management group that handled placing us in our home had mandatory declawing in their standard lease agreement. This was a no-go for us, and we quickly contacted the property owner (who is super awesome, and we lease from her directly so doubly so) and had it taken out. Our landlady didn’t fuss about it, but I highly encourage renters stand up against clauses like this and bring facts against misconceptions against “declawing”.

At the time the re-write started, Django hadn't yet seen a public release, Rails barely existed (and had zero traction, and Ruby-the-runtime was horrible), dotnet was barely a thing, Clojure and Go didn't exist yet, dotnet barely existed. 2005 was a weird time.

Ironically, I think most of Racket's popularity is driven by its Lispiness. People want to get into this 'Lisp' stuff and everyone recommends Racket. I personally learned Racket because as a dumb teen Googled "how to become a hacker".

The first result was Eric Raymond's article How To Become A Hacker, which recommended learning Lisp. I looked into Lisps and ran into the book How to Design Programs which recommended the IDE DrRacket.
Sorry, I meant for the customer. I agree that Amazon could both better validate and indicate to the customers which vendor are the official manufacturer, as well as allow you to opt out of comingling and actually say you want the item to have been from that vendor (even if at an extra cost)

But if there were no marketplace such as Etsy, Amazon or Ebay, I think it would be harder for the customer to trust a random website. At least with these marketplaces, you can trust the payment channels, the security of the data you give them, that the support contact will be responsive, that the item will be delivered properly and at all, etc.
Given that the speed of light is around a third less in currently installed fiber than it is in a vacuum, LEO could be in theory comparable. Also, beamforming phased arrays could presumably replace dish tracking given the distance is not that far and having the signal have to go down to earth midroute would also seem to be an unneccesary requirement. I agree that weather will more than likely poop on your signal though.
What's even more frustrating is that its impossible to find even a brand that uses good quality fabrics all the time. Even expensive outdoor gear can be hit and miss.

Not everyone responds the same. I hated when people would use fluffy language: "would it be okay if you could do X?" Dammit...just tell me to do X. I know you're not really asking me you're just trying to be nice for something that has to be done.

Well... turns out just because I like to hear feedback or orders directly, doesn't mean everyone else does. Part of why your manager treads carefully is because they have to try and create a shared language across your whole team (and really good managers know how to talk to each of their directs because they know exactly what kind of tone is effective for each of them).

Not everyone is the same. Understand that everyone likes to be treated well, but the way you do that is different. Empathy is an extremely underrated skill to have.
