I think you're talking about a different type of mistake than nitrogen is. You seem to be talking about accidental discoveries, or discoveries that were discovered while using mistaken techniques.

When Alexander Fleming discovered that penicillin fought bacteria, he was not mistaken at all. He was spot on- it did kill bacteria. Sure, its discovery may have been caused by a mistake, but what he learned about penicillin was correct, as far as I know.
The main problem with analog computation is lack of reliability (analog is not always deterministic and manufacturing defects are more difficult to eliminate) and density (analog components are usually much larger, in part to increase reliability). That's a huge blocker for faster chips. How do you think we will get around those problems?

Also, perhaps I'm misreading their paper[1], but that DARPA project is still using digital logic. In fact, they specifically say that they decided against using analog computation due to the increased density of digitial (one of the main problems with analog computing, as I mentioned). Regardless, it's pretty clear that the project doesn't have the goal of replacing general purpose computing, so I'm curious why you consider this evidence that analog computing will replace digital computing?

Finally, in what way are FPGAs much closer to analog computing than microprocessors? The advantages of FPGAs (configurability) are orthogonal to analog vs digital.

Java mapping library between spreadsheet(excel) and object
It's pretty easy to open up a webpage that says "install this extension to finish installation" or update or what have you. Simple fact is, most computer users are not very tech savvy and will trust what their computers tell them if it looks official enough - especially if it's from a major player like Adobe.
You mentioned earlier:

>"I use part of my student loan payments to shield against higher taxes. AKA I can write off the interest payments on my tax return."

and then:

>"All the money I made from the prior years investments + tax return I usually dump into other investments that hold up over time i.e. gold, real estate"

I am sorry but that kind of sounds like you are gaming the system. I don't think the intention of the student loan tax deduction was to allow people to buy gold and real estate but rather to help people to make ends meet. You don't actually need that deduction it sounds like.
The conflict is that in the real world, people have momentum. They take a bit of time to change their velocities. In video games, we are accustomed to sprites that can instantly change velocity and sometimes go from motionless to moving significant distances in a single frame.

The publisher wanted both simultaneously. They wanted the human player character to instantly change direction in response to controls. But, they also wanted the character to move like a semi-realistic human who has momentum and takes a while to change directions instead of like a sprite that instantly changes direction. :/
> "The study of God" is useless

With respect, "God" is just a term referring to a being that has supreme powers that humans imagine to be the best of the best - and different people define these powers and other attributes differently. So even if you are an atheist, the study of Gods can still be an interesting reflection of people and society!
I think you missed one of the points. How many of those 95% of Americans want to/are willing to work in a call center?
It's only a Twitter alternative if people I care about will read what I write, or I can read what people I care about write.

This is a refreshingly honest shutdown notice.

Congratulations to Dalton and co for trying something hard and worthwhile, and wrapping it up responsibly when it didn't pan out.
Or to put it another way, people care more about money than their own privacy.
This is an unfortunate, but not unexpected, end of an era. App.net was created at a time when discontent was high with how Twitter was treating its users and 3rd party app developers. Even though App.net wasn't hugely successful, its existence provided a needed check against Twitter exercising user-hostile control over their platform.

However, it has not been a viable platform (one that people actually used) for many years, so while I am saddened that it is finally being shut down, I'm not surprised. Many thanks to Dalton and everyone who built it and kept it going these many years!
Not necessarily. I'd make some comment about people's price elasticities (or maybe "people overvalue free"), but I'm not exactly sure what it would be.

What PG calls "bets" I would call interesting topics for Newton. Maybe he just liked the subjects. Calling bets is saying he was trying to actually accomplish something out of their studies and work. I don't think a curious mind would work like that. Even in physics, he studied a broad range of topics, not only Mechanics.

Furthermore, you don't need to make a breakthrough in everything to satisfy your desire for knowledge. Even more so for Newton, which was known by his seclusion and introversion.

But given more efficient means of production, isn't it likely our current lifestyles are "easier" than 1929 lifestyles?

Washing machines, for example, use less water than dish washing by hand. Laundry machines similarly. I bet printing presses have gotten better too.

If you accept that maintaining a 1929 lifestyle you can do 16 hour weeks: the price of food alone has dropped immensely, I bet fridges are more efficient than they were in the 30s, not even to talk about automation... Shouldn't we be able to do our current lifestyle with less than 16 hours
Use Amazon Prime, but they'll need to deliver a bigger catalog and better recommendation feature for me to try Prime Music. I have hundreds of songs saved in Spotify playlists, love the selection, as well as the recommendation feature (Discover) - Spotify is sticky for me.
My sentiment exactly. And I agree with Dalton it was worth trying to see if it could fly.

It raises a lot of interesting questions about the sustainability of the "app economy" for me.

The transparency I'm after is that majority of your code can be oblivious to whether it's running in OS or green thread.

So, for example, you could configure your web server to use use green threads to handle incoming http requests but configure other part of the system to run with real threads (for whatever reason).

In the end, internally, it will of course end up similar to async/await - you need to capture the execution state and resume it which is what async/await does. I just want to be able to do it without rewriting majority of my code.

My wife listens to and enjoys Pandora daily. She especially enjoys the curated playlists put together by Pandora. I remember the gimmick at launch had the system build playlists for you based on your preferences. It's interesting to see how the service has pivoted to provide a more radio station-like experience.

What other services do folks enjoy? What's the best streaming service out today?
They don't necessarily have to be louder but the two AC units shown in the photo appear to be of the 'louder than a car idling next door' variety. At full bore on a hot summer day you probably wouldn't want to try having a conversation within 10-15ft of them. Hard to say without knowing the details of the sizing or any aftermarket soundproofing they may not be visible in the photo. The neighbors may have a legitimate reason to be upset.
Totally. I pay the $15/month for Spotify family (up to six people); I have Amazon Prime and I've never once used a Prime digital service.
And when you show a reference design for a smart phone with provably strong security capabilities its going to get very real indeed. Kudos for continuing the push toward real parts.
App.net and Medium have the same issue (why advertising is more lucrative than selling blogging software directly to content creators):

Let's say for every one content creator that are on average 100 eyeballs on the content they create (1:100). Almost universally, the 100 eyeballs can be translated to more economic value than the 1, and hence why the advertising model is so lucrative.
I'd love to see those. It's worth an ask I figure.
What you wrote about not needing "to generate certificates" is quite wrong, though I suppose I get what made you think this.

ACME uses public key cryptography in (at least) three separate places, the keys pairs are different in each place. Like completely different - one could be 2048-bit RSA, one could be a shiny Elliptic Curve key, and one 4096-bit RSA.

1. Access to HTTPS ACME service over SSL/TLS. Let's Encrypt has a private key, users of their ACME service get a public key, this allows them to be confident they are dealing with the genuine Let's Encrypt ACME service

2. ACME accounts and associated challenges. Every would-be subscriber using an ACME service must create an account, this account has a private key (which they know, usually stored in a file on their computer) and a public key, which they send to the ACME service.

The ACME private key is used to sign data in ACME challenges. This proves that whoever is passing the challenges (e.g. by putting files on a web server) is also making the ACME requests. This provides the confidence to issue certificates to the account holder.

3. The SSL certificates have a public key baked inside them, which corresponds to a private key owned by the subscriber. The subscriber proves they control the private key and want a certificate by signing a Certificate Signing Request, CSR with their private key.

The Certbot software often used with Let's Encrypt automates most of this, making the key pair for (2) automatically and just requesting you OK a PDF describing the rules for Let's Encrypt. By default it will make the key pair for (3) as well BUT if you're getting a certificate for some device that issues its own CSRs, you can hand over a CSR and it will use that one. If it didn't allow this, you couldn't get the right certificate for a device that only issues CSRs, because those devices provide no way to upload a different private key.

--

Finally, we expect that third parties will want to offer ACME services where a mandatory challenge is like "Fax us all the paperwork and pay $50 verification fee" and then you get an EV certificate instead of the DV certificates that Let's Encrypt issues. Also, never underestimate the willingness of big businesses to pay money for things.

Historically, working- and middle-class people have spent all and almost all of their money respectively on 'just living'. House prices are really high now, but other things have dropped. Whatever the combination of prices, 'just living' will always consume all of the income of the poor... unless something truly unusual happens.

> so they can trivially never experience a type error

(car a), a contains 42. Application bombs.

> However, full path coverage does not guarantee that a value assigned a certain tag ... will have that tag in all executions.

Not having the same tag in all executions isn't necessarily an error, and the guarantee is not required. It being vanishingly improbable that there isn't a type error is good enough. A guarantee in this area has limited value; it doesn't anywhere near prove correctness.

> For instance, if you grab a value out of an array, assuming that the value you grab is an object with a certain property, and then access that property, requiring 100% path coverage still admits programs where the property will not be found (or where the property will be found, but have a different type than what is expected).

I'm skeptical. An example program (Common Lisp, Ruby, Python, Scheme, ...) would be useful, which is fully exercised, via external inputs, such that no errors occur, yet more inputs can be found that trigger a slot-not-found type problem, or a wrongly typed value pulled from a slot. It's not that I don't think the program is possible, but that it has to be contrived. I don't care about catching fraud, only mistakes.

I don't think they should be stigmatized, but I also don't think that was really what pg meant to do. How much was Newton able to contribute to theology and chemistry, compared to how much he contributed to physics?

Sure, maybe he just worked less hard on theology+chemistry, or he wasn't good at those topics, but what seems more likely is that there were no useful discoveries to be made there at the time given the tools + world context Newton had.
In SF proper you're probably not going to have much luck unless you are at a very high end salary. Hundred year old Victorian one bedrooms in a crappy neighborhood will start around $3k. If you don't mind roommates though, and you really just want to live in the city, it's possible.

The best place to look IMO is the east bay, from Oakland to Berkeley. It's still a quick BART ride into downtown SF but prices are 50% cheaper than in the city. Other than that San Jose is decent but you will be forced to drive everywhere.

My suspicion is "yes" -- the PS2 wasn't great at memory access, and modern CPU tend to have better caching/branch prediction anyway.
actually, the 'controller' specifies the interpreter to be used at the client, there can be more than 1 and the '1st one in path' is not always the correct one.
I'm curious where the 40x slower figure came from. It would really depend on what you are doing inside the method.

If the method is a small amount of "synchronous" code in a tight loop, then yeah, the overhead of the async call is going to outweigh any benefits (a few orders of magnitude slower).

However, if your method is doing something like reading in a 40MB file to do some processing and calls the ReadAsync methods then the difference will be negligible and you get the benefit of better parallel throughput.
I just received my pandora one subscription renewal notice and it is due on Sunday. I've thought about it and the only reason I would stay with Pandora is that I have trained it to play music I like. When I turn on my station, I know I'll hear music I want to work to. With that said ...

Today was the first time I've listened to pandora in close to a month. I've been listening to playlists through Prime Music .. the free version. I listen through our echos, my phone and my desktop. I haven't missed the tailored station I've built through Pandora over 10+ years. I think you are correct with "good enough."

Oh, and the Pandora Premium doesn't sound like much of a game changer unless I missed a killer feature:

When we first switched to ZFS, we had some ingestion issues. It turned out the problems were caused by poor architecture decisions we made and was merely exaggerated by ZFS. So yes, there was a noticeable increase in latency, but ZFS was only a tiny piece of it.

As others have pointed out, there's no need to store heat for six months. But you bring up a common enough viewpoint, one that I think bears re-examining:

>I'd imagine there's not enough water to do this inland..

We quite often forget that there's no physical limitation on the amount of water available inland. Water is constantly flowing from the oceans onto land, being recycled (mainly by trees pushing it back up into the airstream), and flowing back out and mixing with the ocean.

So the amount of water per square meter of land is limited by only two variables:

* The rate at which fresh water falls on land (liters/hectare/year)

* The time it takes that water to flow to the ocean (years).

The amount of water available on land (liters/hectare) is simply these two quantities divided by each-other.

The flow is fundamentally limited by the energy balance of the sun, so there's not much we can do there. But the time is entirely determined by our ability to design infrastructure and land use patterns that store water on the land in useful catchments instead of draining it off rapidly. Farm-scale dams are one visible way of doing that, but it's much cheaper to store water in the ground via infiltration systems.

The amount of water is inversely proportional to the amount of time it takes water to flow back to the ocean after it falls. So if we want to "wet up" the landscape, we should make it follow a loooong path with a lot of passive friction and storage buffers.

Just to show my math here, in the USA on average there's 715 mm of rainfall per year, which works out to 19,000 gallons for the average 100 m^2 house footprint. And next year you get that much water again.

In extremely arid areas like California it would even be possible to use salt water for thermal storage.
This article is confusing and contradicting in so many ways. To start with, I was expecting some kind of trustless self-contained system whereby everything can be independently verified and concretely recorded in an autonomous system similar to a blockchain. But instead what OP seems to be describing here is more like a distributed database for storing AI training set data (similar to Storj) where he uses the blockchain more as a metaphor than anything specific.

To give you an example, he uses the distributed nature of the blockchain (as it pertains to storing full copies of the chain on multiple nodes) as a model for storing training set data within a distributed system and the benefit he states for this is that since the infrastructure isn't controlled by one person - organizations will be more inclined to share.

The author then goes on to describe how the integrity of training set data can be attested to in the form of ... "I believe this data / model to be good at this point" which is about as far away from verifiable as you can get. The problem is, the article is very high level and its filled with meaningless buzz words and double-speak like "DAO" ... which is apparently something that can be applied to a human-based reputation system and a blockchain (hence useless.)

There are ways to use artificial intelligence as [part of] the reward mechanism for a blockchain by creating an initial AI to recognize specific types of content and then rewarding miners for finding said content ("datachains" in data mining.) And there are also trustless ways for rewarding people for creating the best general-purpose intelligence for understanding a given type of data. But from the author's account its very hard to see if we're talking about anything concrete here as the article is so technically vague on details.

He does go into detail for several of these ideas. But of the ideas stated none of them are discrete, trustless, self-contained systems like a blockchain (or even really need a blockchain) which is a shame because AI, data, and blockchains can actually be unified to create bullet-proof entities (which in my opinion will be much more purpose-specific than any vague Ethereum-type "AI DAO" non-sense.)

Edit: The authors treatment of AI DAOs is worth the read.
Prime Video is very good by the way. Their original series catalog is expanding, but they also have other great shows available. For instance, you can stream lots of popular HBO classics for free (Curb, The Wire, etc.).

Oh, and the video player is excellent. The "X-Ray" feature is pretty nifty when it's done well: it lists on-screen actors, name of music playing, and general trivia. The Prime Video Android app is surprisingly smooth as well, and in my opinion is as good as the Netflix app.

For me, it's essentially a free video service, as I already need Prime for the free shipping.
