What a magical demo! That made my day. I had largely written off console gaming as a never-ending sequence of brain-dead first person shooters. I'm glad to see real innovation in the graphics space - coupled with advances in AI and NLP, I think we could see a crop of incredibly realistic and meaningful games in the next few years.

IMHO, a key innovation that still needs to occur is a shift away from flunky and unintuitive hand-held controllers to a more natural and vibrant method of input. I really liked the scene in the movie Her, for example, where the protagonist is playing a video game and uses hand gestures to control his avatar, all without a physical controller. Wii and Kinect were the first few steps in this direction - I'm not sure what the next steps are.

I think voice input and NLP is an incredibly fruitful space to explore - imagine what video games would be like if you could actually talk to the characters, instead of merely punching and shooting them.
Yeah it looks nice but the price is that it's broken everywhere else and will probably be overtaken by newer engines until it reaches a release. That is...if it ever does.

Otherwise, not many games made it to release on that engine: https://en.wikipedia.org/wiki/Amazon_Lumberyard
All you really need is quoting and eval to get something close enough to macros. Most Lisp dialects will have that much.
Such as? Most software that runs on Linux runs on BSD and WSL as well.
> If you don’t have a problem with user quality then sure, avoid the verification step. But if you have a good reason for the verification step then don’t sweat the drop-off rates.

If you have any contact method for the user (email, SMS, phone) you should be doing some level of verification on it. Users are clumsy, some of them don't know or mistype their own email addresses, phone numbers, etc. Verification ensures you're talking to the person you expect to be talking to.
Ray tracing is a scam to push more hardware we dont need.

https://www.youtube.com/watch?v=RNRp9Y33xWE Can you spot the difference worth >2-3x performance drop?
Of course they are. If they weren’t it would be surprising. Question is what are we gonna do about it? Usually nothing.
If a scene has been filmed in this setup, how easy is it to separate the physical foreground from the background screen if they want to re-composite the foreground with a more detailed rey traced background?
> Investment properties are like stocks, except that retail investors are much more likely to be leveraged and much less likely to be diversified.

If by retail investor you mean the person holding stocks, I disagree.

Most countries allow comically high levels of leverage when it comes to real estate. 5X is normal, 20X is not rare, and even infinity (e.g. no money down) was possible. On top of that I can use a mortgaged property as collateral for another mortgage to another property. It's leverage backed by leverage in the most hazardous way possible.

Compared to other markets, the average real estate "investor" is so leveraged it would make even the most degenerate of WallStreetBets poster blush.
Those were theories to describe specific phenomenas, not facts.

Certain facts are indisputable and not open to interpretation:

Hi guys,

I'm community support at Dgraph. Reading that question. I come to clarify some points.

First of all, I don't particularly know Memgraph internally. So, I'll stick to Dgraph and related only.

About Karimtr's reply

1. The graph model: Although Dgraph uses RDF as input data. Dgraph is not a Triple Store per se - and the RDF we have is a customized version, which means that it is not 100% compatible with any RDF model (e.g. Turtle RDF) - But eventually, many RDF syntaxes may be compatible.

The decision to use RDF was made a long time ago, for reasons that I am particularly unaware of. It was long before I joined Dgraph. We also accept JSON as data input. By the way, I also don't understand why Neo4j uses CSV as input data since it is not a Graph standard. RDF itself would be more acceptable than CSV. I assume they use CSV for strategic reasons.

1.1 In practice Dgraph is technically a "Property graph" like. There are no fundamental differences between the Dgraph's graph model with Neo4j other than the language itself and the way the data is stored and injected.

1.2 In Dgraph the data is stored in KV using BadgerDB.

1.3 Ontologies can be represented in any GraphDB. The difference is that Triple Store DBs have a language created to infer data specifically with the concept of ontology. And Triple Stores has standardized data input for this.

2. That's right. However, I think we will soon have the option to keep it in memory. But I don't particularly know how useful this is. Today you can keep some Memory first data, but with the guarantee that they will be saved on disks. This helps in performance when there is no use of NVMe.

3. We have GraphQL+- which is a rich language and inspired by GraphQL. And we also have GraphQL which is an "API" language that is now native in Dgraph. A friendly front-end language. And it works "out of the box" once you mount your schema. Dgraph creates a CRUD model based on your Schema. This reduces production time for your application and less logic on your business side. We are still adding "Black Magic" so that the experience in producing APPs is exceptional. And less code typing.

About performance. I suggest doing a test against ludicrous mode https://discuss.dgraph.io/t/sharing-some-numbers-from-the-lu...

Cheers.
In the US, lots of things that involve licensing are publicly available even if they aren’t available online.

For example, if you own land, your name is listed in a register along with the purchase date and price. The floor plan for your house is also listed, as is the condition of your utilities.
Not very commonly discussed, but great topic to be aware of. One particularly powerful use of this is in learning models with interaction terms: more powerful than a linear model but still interpretable, [1].

The only reason pizza delivery "works", is because it's a very high margin food.

In no real world can <$5 on-demand delivery work out unless you have a very high volume of order and can pool the delivery.
I recently tried nix package manager and I gotta say - if your pain point is devops it could take away a sizeable chunk of problems. Steep learning curve though.

Minimal Web Browsers: Why You Need Less Stuff on the Browser
Ask HN: What's your preferred output format?
Do you prefer JSON, XML, Plaintext, CSV, XLS, YAML, etc? And why?
Makes sense. I didn't really want to poke at the server itself in a manner any more in depth than firing a web browser at the thing in the normal manner.
This makes it part of the web page though, which isn't useful. Useful is making it part of the browser itself, perhaps as an extension.
You've not been to wild parties, I guess.
Correct. TLS-wrapped protocols don't seek to offer anonymity of the source and destination. They're designed to protect the confidentiality and integrity of data in transit. The best tools we have for anonymity are things like onion routing.
I'd much rather get my food from someone that has not been interacting with the previous 100 customers.

And now every customer after me won't be exposed to me, either.
Are you being extremely obtuse on purpose?

Not everyone is an engineer who have employers fawning over them. A lot of people have few prospects of employment - especially right now - and have bills to pay. So weighing the two options : no food this month, or installing spyware willingly they take the easiest route.
The point is not autonomy. The point is that it keeps you alive, so that you know that if you leave your job, at least you'll still have health care and food, so you won't die by being jobless.

It sets a minimum bar.

Realistically you need both -- a UBI and a union. The UBI sets the minimum bar that all jobs must reach, the Union sets the livable bar for one particular workplace (or maybe a group of similar workplaces).

UBI and Unions serve different purposes. A UBI prevents modern slavery, a Union provides for a decent quality of life.

I think the business model is solid. I think the implementation of said model is to be blamed. However I am having difficulty in logically pinpointing why my kneejerk reaction is to the implementation.

Contrast gig economy (I cannot believe I am using that term) workers of today with milk delivery workers of the past. What's different? A schedule? A subscription?

They charge super-high fees to restaurants and their service doesn't seem that complicated or expensive to run.

What do these companies spend so much money on that they struggle to break even?
Huh? The authors of this (flawed) study are making the claim that Vitamin D deficiency correlates with negative outcomes from COVID-19.

They are doing this by using public measures of country-wide serum-based Vitamin D deficiency rates and COVID-19 outcomes.

How is "where the Vitamin D comes from" relevant at all to this particular correlation? It might be relevant if you're interested in a correlation of Vitamin D deficiency and anything having to do with the sun -- but that's not the correlation they're making here.

I tried instacart for the first time this year because of the stay at home order and while we've had a couple good orders for the most part it has been a frustrating experience and we will change over to a different grocery store which offers their own app and pick up instead of delivery.

A few problems with instacart and other deliveries for me:

- uncertain delivery times. Even when the shopper marks the order as completed it can take up to an hour to get to my door. It seems they bundle orders but this isn't clear and makes me worry about cold or hot food

- inaccurate orders. I have gotten 3 extra ranch dressings which I have never ordered!

- constant changes to orders due to items being out of stock. Not instacarts fault but it is still a bad user experience

- I am tempted to leave a poor review of a shopper but then I think they know where I live! Less than ideal.

Overall I would rather interface directly with the stores and restaurants. There are just too many things which can't be generalized across a platform. New restaurant discovery isn't something I need either.
Can someone steer me to some good benchmarks, discussions of perf characteristics and gotchas of the BEAM? My search-fu is weak and I'm not finding the sort of content I'm after.

I'm trying to learn Elixir and being a systems thinker so before I (can) get too comfortable I'm gonna want to dive into origin stories to build up my holistic map of why things are the way they are, what can be done and what can't be done, and understanding bottlenecks in the BEAM seems like it's gonna have to be part of that (the way I studied JVM tech documentation when I did perf and architecture work in Java)

If Instacart was able to pivot to full end to end food delivery with their own distribution chain it could have long term viability. Their current model of just having people shop in normal stores is problematic for many reasons, not the least of which because normal stores are BY DESIGN slow and inefficient for picking up a list of items.

Instacart had early advantage because full scale grocery delivery infrastructure was broadly in its infancy but if and when the likes of Amazon, Wal-Mart and others go full scale on their own offerings then structurally it would seem impossible for Instacart to compete with that.
What is it supposed to be the output of? I think that it would depend on that

SQLite includes an extension to deal with JSON, and the command shell can also deal with CSV, and I also wrote a JSON parser in PostScript, so that means it can easily be used with PostScript codes too now, and of course JavaScript also has JSON built-in.
Overflight of US airspace does give the US authority to choose who is allowed on the plane, to require the airline to provide specified information to them through the passenger manifest, and to impose other conditions simply for being allowed to overfly. A person born in a plane overflying US airspace at the time of birth is a US citizen. An emergency landing of a flight overflying the US will often land in the US, and a plane ordered by US authorities to land while overflying has to comply. Lots of US influence in this area.

You're right that many direct flights between Canada and Europe or Asia don't overfly the US. Many of the affordable options are via US connections, however, and travelers from the rest of the world to Canada frequently overfly the US.

As for Alaska, it's very much a part of the US, to the level that everything I said above is true for flights which only overfly Alaska and none of the rest of the US.
I think of all the stuff I liked as a kid that my teachers and parents thought was trivial. Watching this, I wonder how much more interested I would have been in school if that stuff had been a part of it, instead of mocked.
> Europe is gelling into a political unit, with the EU and all.

Hejlsberg already designed a language with its own runtime from scratch - that was C#.
I've ordered at least 10 times through the Chipotle app (delivered via DoorDash) and never had problems. I was very surprised to get the food in under <20 minutes.

A few times the estimate was off and from the status/tracking page, it looked like the driver was making another delivery before mine, but that didn't delay my order more than 10 minutes or so.
It is not merely that people are old that makes them susceptible to Covid-19. It is other factors that correlate with age that make them more susceptible. One of those factors could very well be lack of vitamin d.
The ULA triumvirate is different from the others. There are few businesses that can survive prolonged quarantines without outside help.

The fact that delivery business is having trouble in the most fecund business state is a testament to the (non) viability of the business as structured.

In other places food delivery is assisted not by expensive four-wheeled vehicles but by cheap two and three-wheelers.
I've also seen 20% improvement with TypeScript when working with developers in a big corporate environment (especially when no one cares about the project and everyone gets paid hourly).

But when working with senior developers on open source projects (when people don't get paid), I've seen at least 50% drop in developer velocity using TypeScript and lower code quality.

My theory is that developers who are passionate about coding don't need TypeScript to produce high quality code. It mostly just takes the fun out of it.

But I guess if there is no passion to begin with, then I can see how TypeScript can't hurt in that respect. I've worked for a company like this once for 6 months; I had to quit because I enjoy coding too much to spend most of my time writing and renaming type definitions and waiting for the compiler.
1. I'm sure there are software engineers in Ohio working remotely making 500k and more, but no it's not the norm.

2. That's not the point: we're talking about a hypothetical shift where top software engineering talent is fleeing the bay area. If that talent moves to Ohio, and there is no cheaper alternative of similar quality, Google might not have a choice.

Again, not pretending like I know what's going to happen. My point is that big-tech doesn't have total power in setting prices. If at any point in the last 20 years they could have hired qualified engineers in Ohio for $100k they would have already done it.
This is looking at population-wide measures of Vitamin D deficiency from before COVID-19, so...maybe the argument you're making is that these populations with lower Vitamin D were already sick and thus more prone to COVID-19?

Because they're not measuring post-COVID-exposure Vitamin D levels.
This actually exists for pickups already in Canada, called Ritual.

A recent $30 Thai dinner for myself and my wife came to $58 after delivery fee, service charge, and tip. Ridiculous for the convenience of saving 20 minutes (round trip) of drive time.

Of course we didn't pay it did takeout instead. I feel bad because there's a tier of service workers that I'm not supporting anymore, but marking up ~100% prices us out.

This would be awesome tech if everyone had gigabit fiber. You could just stream all the assets during loading time or if possible during gameplay. On second thought, 125MB per second probably wouldn't be fast enough. A 30 second load time would only result in 3750mb of assets at best. 4k on a Google Stadia doesn't sound bad if the latency is good.
> I think you overestimate the ratio of riot cops to renters.

Nope, I watched the conflict between the WTO protesters and cops first hand, and got caught out during the beer riot of the SLC Olympics. Crowd control is scary effective, and it's backed by lethal force including rooftop snipers. Folks will need to come with gas masks, body armor and armor-piercing rounds to overtake the riot cops. The folks willing and prepared for that aren't nearly as populous as "renters."

But then what happens? Is the auction "legitimate" after this escalation? The aggressors would need to overthrow the courts as well. Not saying it can't / hasn't happened, but it's quite a leap.

> There would be essentially no way to find who did it, following the principles of stochastic direct action.

The surveillance state is pretty bad too.

Here, we agree. A second civil war has seemed like an obvious eventuality to me since circa Bush II.

We have been saying for years, posting financial statements, showing hard bottom line figures, that these SV unicorns are unprofitable, trying to undercut the existing markets by funneling in VC money to make up for the lack of an actual profit.

Take Uber, for example.

You cannot, in all seriousness, charge a piss poor amount for a 30-minute taxi ride, and then take a cut from it, and expect people to somehow be okay with it. It doesn't work and it's disrespectful to people involved. It ruins the economy and no amount of handwavyness about market forces will make things better.

The same thing here applies to their food delivery businesses.

There is a reason why what they are doing is illegal - predatory pricing. But they think they are too big to fail.
Under and unemployed people staying in their homes are not going to order. They save money. People working from home could order but many of them feel insecure abut the future and also save money. Notice spike at the end: https://fred.stlouisfed.org/series/PSAVERT (the Dec 2012 spike was due to accelerated payment of bonuses and compensation in anticipation of increase in tax rate)

You can innovate and VC all you want, but it the demand decreases, so does the revenue.
I'm curious as to how a basic app could replace the on demand delivery logistics / handle the volume that a platform like UberEats sends to restaurants ?

Maybe my urban area is different but restaurants here are doing 10+ orders per hour across all delivery channels. The bottleneck becomes the # of delivery couriers available and smartly assigning them to deliveries.
Though we've relied on TLS tunnels universally this required a node on each end of the connection. Great for management and availability, not so great for ease of use and cost. With Wireguard users can manage their own endpoints and still expose networks/hosts into our virtual network overlay.
Why is it surprising?

SMEs tend to buy cheap laptops, that come with "free" Windows Home. (I don't that that version can even be added to a domain)
Then they start expanding and just stick with "what works", until it doesn't.

But I see this dropping drastically in the next decade, as PC replacements(read even cheaper Chromebooks and tablets) take more hold and web takes over even spreadsheets.
Why Agile Velocity is the most dangerous metric for software dev teams
Food delivery the traditional way (the pizza delivery guy) is profitable for restaurants and provides a wage for the delivery person.

If there's a problem with things it's the model of the delivery apps and sharing economy, not the economics of food delivery itself.
So if you have high standards instead of being content with mediocrity, you.. have a problem? Well, that kind of thinking most certainly would encourage people who want and can do better to leave.

"This is crap" is, for a lot of people, a way to say that this is utterly mediocre (aka. not good, and not satisfying).
I would love to work at the same company until I retire. The problem is that to actually make more money and gain skills you MUST, as a software engineer, hop jobs every 2-3 years. I wish it weren't so, but that's just how it is right now. Add to it the fact that most companies don't care to actually train or retain their talent, and you've just got more incentive to hop.
Probably the efficiency of a milk route, you can do more of a traveling salesman walk. Rather than a one order to one driver, which is probably substantially less efficient. Amazon/Wholefoods doing more of a scheduled delivery might be a money maker in the long run, it is less gig like though than Uber Eats, Grubhub, etc.
Bingo.

Subsidized not only by VCs, but also by gig economy workers who genuinely don’t understand how little they’re being paid because their liabilities are complicated and often hidden/deferred.

This seems to happen a lot especially with food service startups, because of how price-sensitive that market is. Selling anything below cost or undercutting the competition by even a little bit in that industry will give you exponential growth for as long as you can sustain it, but the instant you want to turn a profit the market will turn their back on you and go somewhere else.
