You’ll be interested to read about aspect ratio: https://en.wikipedia.org/wiki/Aspect_ratio_(aeronautics)

As the ratio of the span to the chord increases, the ratio of lift to drag increases as well.

The drag of an object in the sense of forcing its way through the air (eg a semi truck on the highway) is important, but for airplanes there is also a very important phenomenon of drag due to lift (“induced drag”). It’s kind of non-intuitive. But if you’ve ever seen those strong vortices coming off a wingtip, you’re seeing induced drag. Think of the energy creating this: https://youtu.be/uXrnGiIMGLs

It’s energy created by propulsion but turned uselessly into spinning air.
Because the same way rent-controlled units trend towards deregulation as a result of death, Mitchell-Lama co-ops trend towards privatization and no longer being a part of the Mitchell-Lama system.

I think the FAA is more concerned with 500+ people on a high-explosive ballistic missile we call a 777 than they are the one or two people on a plane they built themselves. I'm not sure how you begin to compare the two.
I am not in anyway an aerospace engineer, but from the bits I do know about airline safety, but that seems like a pretty obvious question to ask so I feel like this scenario has to have been considered.

We just had that southwest flight land with a missing engine and a hole in the side, and back in the 80s we had that hawaiian flight land safely with the roof ripped off (https://en.wikipedia.org/wiki/Aloha_Airlines_Flight_243). Modern airliners are built to fly in some pretty insane conditions.

I wouldn't want to be on the plane to find out, but my gut says you'd be fine.
I'm pretty sure that at UBeam they are following this with some anxiety.

Still, the investors that sued (who got back ~half of their investment) only have themselves to blame.

The part that I think they should go to jail for is the health aspect. That's something you don't mess around with on any level.
I had a Cassiopeia with WindowsCE in the late 90s and a program called Calligrapher that did this. I was impressed because I have horrible handwriting and it was able to consistently recognize it.

So it's always strange to hear that no one offers handwriting recognition on these devices.
I once was in Manhattan with Dr. Engelbart during the NIME conference (New Interfaces for Musical Expression). We were riding the subway together. I think he must've seen the poster (presentation) I was carrying and we struck up a conversation. It ranged over all kinds of topics: ergonomics, performance/audience interpretation, mechanical vs. gestural control, etc. I remember us being pretty sharply critical over each other's ideas, and just being skeptical of "good" solutions in general for the problems of modern musical control.

Of course, I didn't realize who he was at the time. I only had seen grainy old videos of him from decades ago. I'm really glad I didn't recognize his face at first. You see, he had always been a huge hero of mine, and a big motivation for me to go to grad school. For a brief moment, we got to argue over small technical details as if we were any old pair of jaded researchers. It was a totally normal exchange in any other context, and a highlight in hindsight.
> Grab two versions of the package (1.5.1 and 1.7.3), rewrite the import paths of the stuff that requires 1.7.3, and kind of opaquely have two version of the same thing?

Yes, in systems like Cargo you end up with multiple versions of the same package. This typically "just works". It works so well, in fact, that often times people don't even realize they're using multiple versions of the same package, and they want Cargo to report an warning here.

> This seems a fairly reasonable tradeoff; on the upside is a _very_ fast, very simple, and very predictable dependency manager.

For other package managers, speed of the core dependency resolution algorithm has never been a problem for me or anyone else I know.
Seems like every comment at this stage is about getting shafted when your startup gets an exit. Other than supposed the lack of politics and more bleeding edge tech - what is the point of working at a startup if you aren't looking for an exit? (Especially for early hires)
This is not Adobe's first e-commerce dance.

Adobe attempted an acquisition of Hybris Software, a Java-based e-commerce platform back in 2013 (see first link). This would have meshed well with their Adobe Experience Manager, their CMS solution (an integration already existed, and was also based on Java/Spring). SAP offered Hybris the opportunity to operate independently for two years, and Hybris was acquired by SAP.

What is surprising is how AEM and Magento will integrate, considering that AEM is a Java/Maven based CMS and Magento is PHP.

Extra Credit History did a really great animated history lesson on this: https://www.youtube.com/watch?v=fgQahGsYokU
Wing efficiency increases with the wing's aspect ratio, and the aspect ratio is the quotient of the span (b) squared and the area (S): b^2/S. So making the wingspan longer with relatively little increase in wing area increases efficiency.
The challenge is 'we' is not a homogenous group within a city such as LA. In fact they are very much heterogenous groups lumped together.

We want affordable housing = existing residents who want to rent their affordable apartments or continue to own their single family house without additional traffic/school overcrowding and their network of friends to have that opportunity too, politicians who want to represent these folks

We want tech jobs, more office space, more apartments = real estate developers, young tech professionals who want job options, incoming residents who aren't aware of how uncrowded these neighborhoods used to be, politicians who want to represent these folks

> And for legally binding documents the tenant has to deliver within a deadline, he can, if it's that bad (at least in Germany), pay a court bailiff to deliver the document and certify this delivery.

That's true in the US as well, but again, the point is that a landlord who wants to make your life hell and drag you through the court system has plenty of opportunities to do so.

A conversation about how minds change with Misha Glouberman
well, I'm grateful for some of the sense in this forum. i know PC and he's one. that's it - the end of the story. but some of these twitter and blog trolls don't care about real-life consequences. I agree with Shivetya that protecting the right to anonymity - particularly in thsi vile manhunt - should be paramount. i think PC is probably experiencing a lot of stress and would welcome some more solidarity around this. twitter has been rife with speculation, people post addresses on forums, someone even posted a death threat on craig murrays blog in the comments today... i mean , come on... anyone got any suggestiosn how to handle this and de-escalate? it seems totally unwarranted (as you say, he's prolific but not even in the top 300), and is getting really serious... :(

Probably a bad assumption given that this model is not flying yet.

The FAA's approach is that any kind of problem that has been seen already needs to be investigated. Planes crashed on some other model because flaps were not locked on takeoff? That type of error goes into a checklist of things to look at. Now everything that needs to be right for takeoff needs to be locked into place!
memcached had already been around for years before Magento - if they needed an example of how to do a key/value store.

We we using that back when it was a LiveJournal Perl project, probably late '90s. There were a bunch of "persist memcached to disk" projects too - from memory we used a Java thing called Prevlayer or something...

Having said that, I too mis-used MySQL as a key/value and EAV store back then, because it was the pragmatic choice at the time. If some of my work from the late '90s and early 2000s had grown into platforms still being used today - people would probably be questioning my sanity for choices like that as well...
Very inspiring. Made me happy - to know that after programming for 28 years, I might only be half-way through my career.
The market is very good at allocating resources, setting prices, and meeting demand.

Countries with freer economies like Switzerland and Hong Kong have higher standard of living on average. Countries which free up their economies have higher relative standards of living after doing so. Countries which oppress their economies have lower relative standards of living after doing so. (By relative, I mean relative to the growth rates of neighboring countries and before the changes, as standards of living rarely decrease absolutely).
According to the recent update of the Japanese Telecommunications act, its illegal to record the packet payloads without a court order. However recording the headers, e.g. TCP headers if fair game.

So its perfectly legal for ISPs and agencies to record the metadata. Then again Japan dosent have freedom of the press and many other things you might expect.
I don't know if this is still the case, but at least in 2010 Reddit used Postgres as a key-value store [0]

> All Holmes & Co have to do is to claim that they thought it would work and that if there was a critical flaw they only became aware of it long after the investment was made.

you probably missed (it was just on radio) how Holmes & Co showcased their tech by conspicuously loading samples into the machine and then leading the audience away while rushing the samples to Siemens hardware and presenting the results from it like it was produced by their own machine. Basically investors got a slew of hands of a birthday magician for 400M (though for that kind of money i think even Houdini would rise from the dead to do the show in your backyard)

Since at this time you seem to be the first user of the f word on this thread, it seems like a good time to say that me and a lot of my database friends and colleagues use Magento as a replacement for it. So you could rewrite that bit of your comment as "what the Magento?" and it would not lose meaning for us!
That's my biggest reservation about Sony products. They treat software and computers like consumer electronics that are expected to function with a fixed feature set from the day they're born to the day they die.

I can see the merits in this for the less tech savy and that might have made sense in the 90s but not today.
In Search of Dark Stars (2014)
I have had the original DPT-S1 since 2015. I got it before starting school and have used it for textbooks throughout. Weighs a few pounds less than any textbook, let alone all my textbooks. For this it is amazing.

For handwriting... Not so much. Can only write with one hand in one orientation.

New split screen mode is pretty tantalizing. I could be persuaded to upgrade if this model has a better stylus situation--I could stop carrying a notebook altogether most days.

It's not. The suit Janus actually filed is the closest thing to that.
> Under what crimes would you like them charged?

They apparently (based on statements from employees involved) falsified FDA filings under direct pressure from executive management, so, good old 18 USC § 1001 [0], the catch-all crime of lying to any federal agency about anything within it's scope of concern that usually gets trotted out as a reason never to speak to federal law enforcement without the advice of counsel would seem among the more probably potential charges.

Skimming over the excerpt (I haven't gotten that far in the book), it seems to be omitted, which makes sense given that the excerpt focuses on the company's corporate dysfunction. I have to admire Carreyrou's and his WSJ editors' restraint in not reporting such a salacious detail during the course of their Theranos investigation, because a case could be made that Holmes's and Balwani's relationship is germane to how Theranos turned out.

> In early August 2007, Ed accompanied Elizabeth to Nashville. Sunny picked them up from the office in his Porsche and drove them to the airport. It was the first time Ed met him in person. The extent of their age gap suddenly became apparent. Sunny looked to be in his early forties, nearly twenty years older than Elizabeth. There was also a cold, businesslike dynamic to their relationship. When they parted at the airport, Sunny didn’t say “Goodbye” or “Have a nice trip.” Instead, he barked, “Now go make some money!”

Or maybe, perhaps the damning evidence against Theranos was so voluminous that the Holmes+Balwani relationship was small potatoes in comparison and not worth the newsprint.

edit: The WSJ recently published an excerpt of the book's chapter devoted to Balwani. Here's the Twitter link (WSJ paywall seems to let in twitter.com referral domain): https://twitter.com/JohnCarreyrou/status/997522528301174784
As tempting as it is to just completely diffuse the blame and claim its "nobody" or "the system", there are humans at the tip of the spear. Even if its just the lawyers who choose to take the case or the muscle who shows up to do the eviction.

You beat me by two minutes on the aspect ratio bit :)

Here's another good video showing wingtip vortices: https://www.instagram.com/p/BhzCLgFnVzL/?hl=en&taken-by=edse...

Not sure what you mean by "energy created by propulsion." The vortices result from low pressure on top and high pressure below making the air want to curl around. That imparts downwash on the wing, reducing its effectiveness.

>> Instead, focus on declarative properties: Does your predicate (or DCG) succeed in cases it shouldn't? Then your program is too general, and you need to add constraints. Or does your predicate fail in cases it should succeed? In that case, at least one of the goals is too specific. You can use declarative debugging to find out which goals are responsible for the failure.

That's good advice and I realise it articulates the way I reason about why my programs fail when they do (which is all the time).

The problem is when reasoning doesn't shed any light on what's wrong. There are many such situations for me, often caused by the fact that Prolog still manages to surprise me even after many years of programming in it.

For example I recently found out that findall/3 (which I use liberally) actually copies terms with fresh variables causing subtle changes to the structure of a term that are hard to detect with the naked eye. It took me I think an hour or so of debugging my code until I realised (and accepted) what was going on and I still had to go on to the Swi mailing list and ask, just to be sure. This is not something you can reason about, unless you know the semantics of a specific predicate (in this case, findall/3) in detail.

In another recent example I was debugging code that backtracked over the combinations of a set, waiting for that one combination that caused the problem to reveal itself. It's very difficult to just reason about situations like this, when almost everything works but there is a subtle bug hiding in the wings.

In my experience, kids recognize the brightly-colored sanitized tools as "not real" programming. The moment they hit the overwhelming UI or unfriendly error messages of many environments, they feel under-prepared for "real" programming and take a hit to their confidence.

I tentatively agree with them. If I can take a stab at what "real" programming is, it's when you can't expect everything to just work out of the box. You can screw it up in unexpected ways. Sure, that's demoralizing. But you either win or you learn, and I wonder if winning too much, too early prevents cultivating the mental ruggedness it takes to really program.

Same. I'd stop somewhat short of saying "I like Magento just fine." - but I'd admit to having continued to select it as the least-worst option, even after having been burnt by it several times previously.
I think in this case contemplating preferences might be more important than rights.

How much do tenants actually value a guaranteed right to live in a given community? When we look at anywhere in the U.S. that isn't rent controlled, we figure out, it's not much at all.

There is nothing illegal about signing a very long lease with a landlord. Commercial real estate contracts routinely include a a clause which allows tenants to extend a lease at a very similar price for many years in the future.

Landlord would absolutely love to do leases like this. But the reason this doesn't exist in the non-commercial settings is because no one cares enough about living in a place long enough to actually pay for that option.

Rent control only exists because its a a popular transfer of wealth, and is emotionally appealing, not because it actually makes people better off.

This is the most "BMW driver" quote I have ever read.
I own the DPT-RP1 and regret purchasing it. If you compare it to the latest iPad Pro the battery life is worse (no joke), the handwriting is very laggy, the end of the pen wears down like a pencil, the software is a joke, the lack of blacklight disappointing and the lack of updates or third party apps unacceptable.

Remarkable looks genuinely interesting.
I wish all companies had the internal connectedness to be able to react to realtime updates and coordinate the exact split second to hold up the friendly stop sign!

There have been few stories on here of bounty hunters who've either been scared to go any further than they have, obviously giving the remote end a good excuse to pay less; or who've taken things slightly too far, generating mildly put-out emails and stepped-on toes (which can't bode too well for future interactions).

So this the best thing you can hear from that standpoint as well.

Straightforward communication seems to be a holy grail, which is understandable: besides needing full internal access to all the areas affected by the full scope of vulnerability (either directly or via intermediaries who are good communicators) so you can figure out when to hit the stop button, you also need to have the resources to delicately balance management risk and developer egos.

That sounds like a "fun" job...

I guess this demonstrates the fundamental requirement of security: the recipient is the one who needs the non-broken understanding of security, both a) properly in and of itself, and b) how it relates to the domain they're in.

There are a thousand public examples of where this has been gotten hopelessly wrong; my bookmarks are a mess, so here's the (somewhat poorly related) one I can remember how to find via Google (it's as bad as all the others, wouldn't mind being reminded and learning about new ones). This one is not the same kind of vulnerability (there's no need to coordinate pushing a stop button, it's a data breach), it's just an example of grossly misunderstood security and utterly broken internal communication.

Prosaically, the elderly have higher voting rates than the young so they win this fight.

Philosophically, I don't like placing two sympathetic groups on opposite sides of a scale and weighing them, because that's usually a false choice and there is some external factors unaccounted for that make the choice less normative. In the case of rent control, this externality is clearly that it depresses new unit construction, exacerbating the problem. So I oppose rent control.
Latency on the DPT-RP1 is exactly the same as those third party pens with an old iPad. Very noticeable.
