I think the flash card space is interesting because I think Anki users are very much "power users". Because it takes a curve to learn how to use it (poor UI) and there are lots of extensions, the type of person who ends up using it is a more advanced user.

The rate limiting is a big issue and I think something can be overcome. I'm working on my own app and what I've done is made it so you can limit the number of cards you review per day. Your daily lessons will usually be some combination of overdue cards and new cards. However, if you have too many overdue cards, there's no point in adding new cards to your lesson.

I know with SRS reviewing a card "just before you are going to forget it" is a big part of why people believe it's effective. However, I think that's just an imperfect model, so I think if you push an overdue card by a day or two, it'll still be effective. (i.e. there's no reason to force someone to review cards on a given day, obviously there's a window here where if you review too far in the future, you're going to find it harder) With this in mind, I made it so if you rate limited your daily lesson, the app just pushes the overflow to the next day. I think there are also other variables that make the models imperfect (some facts are easier to remember than others, how you present the content might make it easier/harder to remember, and so on).

Regarding easy input, I'm not familiar with how easy or hard it is to input images and audio, but I made sure that my app allowed a super easy drag and drop. In general, the app should make it incredibly easy to create new cards, edit existing, and add various media. Cards are the lifeblood of the tool, so working with them should be super fluid.

As for other modalities, I think that's an interesting topic to dive into. With self-learning applications, you have to balance making the most general use cases easy. Once you started adding more complex card types, your UI is going to have add affordances to make those possible, which has the effect of making it more challenging for the novice (who just uses text, images, and audio) to use.

Anyway, to sum up, it's definitely an interesting space because you have power users who may want to pull your app one way and regular users who may pull the app another way. I think finding the right balance of features is a challenge.
Yes, the goal was/is to start with a very high level example then get more into crypto specific concerns.

The audience is for devs without any real experience/knowledge of using crypto that might go into it too casually.
Since Machu Picchu has been at least partially restored up to an arbitrary level of "ruin-ness", I wonder how much of this impression is due to that vs. the original construction.

I have the impression that the place has been optimizing for maximum tourism, not preservation, for some time now.
It compiles to JS, ARM, and x86, for web, mobile and desktop support respectively.

Also, Dart has code generation so you can write your own language features, like the freezed package which implements algebraic data types even though Dart doesn't have them natively.
1% chance is for you. But if you are able to infect another person, that is no longer 1% as a whole.

> Pre-made decks of cards on a range of subjects available on the web ("shared decks").

This is of very varied quality though. Some decks are made by university professors that teach a class on an advanced topic, and they are top notch. Other decks are simply wrong, and questionable. This especially applies to language learning, since people creating the decks aren't proficient yet.

That's why I loved Wanikani [1]. In the end, it is just Anki with some extra stuff, but you pay for the excellent quality of the content.

Yes.

EDIT: I'll clarify. You refer to safety. I grew up in a place where being outside as a teenager was perfectly safe, also at night. I want the same for my kids, and it's totally achievable. I think the whole idea that the world is somehow "unsafe" and that the parents need to constantly helicopter to guard their offspring from all the evil pedos and thieves and lunatics, is a fundamentally harmful idea.

Now, I do recognize that America is pretty scary, with their gun laws ensuring that either a gang member of a cop can shoot you dead on the spot if you dare take a snickers out of your pocket while they see it, but not all places are like that. Iceland sure isn't.

There's no good reason, in affluent places at least, for "the outside" to be dangerous. And if it is then that's the problem that needs to be addressed, not parents who want to allow their kids to learn their own life lessons.

I think this article has plenty good ideas but I don't think legally enforced helicopter parenting is one of them.
But even those services are sometimes questionable in actual value (and overall experience.)

Example: At the college I went to, the food service company that handled the cafeteria had some interesting clauses in their contract that gave them a lot of control over who else could cook food for an 'on campus/university sanctioned' event. It's been a long time so I can't remember the specifics, but I think we had to switch some fraternity events from cooking hotdogs/hamburgers outside to just bringing some Carry Out pizza.

On top of that, the workers for that company weren't paid well, the food was typically about what you'd expect from, say, bulk purchases from Gordon Food Service, and very expensive for students.

Speaking of that, IIRC if you lived on campus you had to have some form of meal plan (I assume that was also in the contract.)
Again, the number filter mangled the title. The full title from the article is "Inside the 8086 processor, tiny charge pumps create a negative voltage". In the interest of brevity, "processor" could be omitted or replaced with "chip."
Both the FoundationDB docs and Spanner whitepapers are very clear that their definitions of strict serializability match with the conventional academic one. FoundationDB does keep track of the read set of every transaction: there are nodes dedicated to doing that in their architecture. You can even add things to the read set of each transaction without actually reading them to get additional guarantees about ordering (e.g. to implement table-level locks). FoundationDB (and obviously Spanner as well) don’t have any massive penalties for this; FoundationDB clusters can handle millions of operations per second with low single digit read and commit latencies: https://apple.github.io/foundationdb/performance.html.

If your condition for believing these claims is approval from Jepsen (i.e. Kyle Kingsbury), he apparently didn’t both testing FoundationDB because their test suite is “waaaay more rigorous”: https://twitter.com/aphyr/status/405017101804396546. In particular their test suite is able to produce reproducible tests of any variation in messaging (dropped messages, reordered messages) across their single-threaded nodes, which is extremely useful in narrowing down places where serialization violations can hide. He also seems to believe Spanner’s claims: https://www.youtube.com/watch?v=w_zYYF3-iSo

I’m not sure where this “conventional wisdom” about serializability having an unavoidable large performance hit is coming from; the databases I mentioned are very well known in the distributed systems field and not some random vendors making outlandish claims.
Interesting to see the difference in perspectives: Reddit is jumping on that quote about it being a bug and saying it's definitely intentional, while HN is taking a more conservative approach. Personally, I always err on the side of bug/incompetence rather than maliciousness in matters like this because even Facebook isn't brazen enough to pull something this obvious.
Washington Post settles $250M lawsuit filed by Nick Sandmann
Depends how you sport. In London, my daily 15km cycle to work would have me constantly starting and stopping, sprinting small hills, dodging tourists, racing fellow bikers, brushing cars, and basically being alert at all times for any and all dangers (this was before the mass cycle lanes). There was a weird adrenaline induced rhythm to it that would grant me both physical and mental relief everyday that I had somehow made it to work without dying.

Since I've moved to the countryside; boring endless gentle hills, breathtakingly stunning scenery that offers no challenges, and my brain basically goes into autopilot. I get to work feeling physically fulfilled but mentally drained.
Firefox at least has DNS over https enabled by default.
Thanks, that’s even more interesting. I thought cuckoo filters were near the theoretical limit of information density so it looks like I have some more learning to do.
Dart has compile time ADTs with the freezed package. I like Dart since it has code generation features so you can write or import custom language features, much like JS with Babel.

Yeah, especially when trustworthy news and facts are all the more important now.
I agree that "Teaching Isn't About Managing Behavior", in the same way that programming isn't about avoiding syntax errors and driving a car isn't about staying between the marked lines on the road.

I was a teacher for fifteen years. The writer of this article started about the same time I got into the profession, so has nearly 20 years of experience.

The first thing you need to do with any class is manage behavior. This can be tricky in your first couple of years, but after a while it just becomes part of who you are. You're more confident in the classroom, you have a reputation in the school, you can recognise and shutdown disruptive behavior before any of the other kids have realised something is about to kick off. At that point your classroom changes, and you can practice what the author calls "Reality Pedagogy", or any other type of pedagogy you like.

Believe me, having observed and mentored plenty of student teachers over the years, the first thing you need to tackle is behavior management. Once that is established then you have the opportunity to be the "captain, my captain" teacher, or whatever you like really.
I don't think we could do that without also removing the Federal government from the student loan process.
I think the key here is that it's a bug in iOS, not in Instagram. So FB isn't even the responsible party.

Additionally, it's a beta version of iOS, so we're supposed to be expecting bugs anyway.
What are the security guarantees about this?
Samsung has been assembling flagships in India for a couple years now. Certainly not new. New for Apple definitely.
No it isn't (outside shortening to fit to HN title length I assume), and no it doesn't? It clearly quotes an Instagram spokesperson saying it's a bug and that Instagram is fixing their app?
While you are right in a sense, if you don't make a constructive point with your assertion it's just pointless arguing.
I'm really hoping this will make AngularDart a lot nicer to write. Inputs might have a null value and it's very easy to forget to account for it, will be great to catch that at compile time.
I don't believe I've abandoned any middle ground. I can come to the defense of those arguments. They just don't seem relevant to the urgent question of how to get rid of the mobs trying to burn down the courthouse. I'm sure we can agree that federal agents manning siege defenses every night isn't a workable long-term solution.
Ebert really didn't enjoy it. I assume you have good reason to recommend. What did he miss?

Apart from the bonding mechanisms of sex that they mentioned, the strongest natural love drug I've encountered is newborn smell.

Somehow for the first few weeks after they're born, sniffing a newborn releases a powerful hit of dopamine and oxytocin in the brain. https://www.smithsonianmag.com/smart-news/the-smell-of-newbo...
Obligatory favorite obscure book that everyone should at least have read a Medium summary of citation:

https://www.amazon.com/Keeping-Together-Time-Dance-History/d...

Super-tiny summary: humans have used coordinated rhythmic movement and the feelings it evokes as an aid to build communities and create efficient synchronized behavior. This behavior may even predated the human separation from other apes, and there is some evidence that certain other modern apes may use this too, though to a more limited degree.

If this is truly such an ancient mechanism (the author's case is not ironclad, but good), it wouldn't be surprising to find connections between "coordinated rhythmic movement" and brain function.
If we are looking at brain effects, the advantages must outweigh the risk of brain injury inherent to the activity. Playing football might help brain plasticity but at considerable risk of brain injuries. Most all the team sports (soccer, lacrosse, hockey etc) have varying degrees of associated brain injury risks, but not dance or other non-competitive sports. At lease when dance (or rock climbing) is competitive the competitors do not share a movement space and so don't knock heads.
Looking at this:

"Dancing compared to conventional fitness activity led to larger volume increases in more brain areas, including the cingulate cortex, insula, corpus callosum and sensorimotor cortex. Only dancing was associated with an increase in plasma BDNF levels. Regarding cognition, both groups improved in attention and spatial memory, but no significant group differences emerged. The latter finding may indicate that cognitive benefits may develop later and after structural brain changes have taken place."

May I translate: They saw improvements in things they could easily measure. They hope this translate into improved cognitive ability. But it actually didn't. But they still hope it'll do that later.

(FWIW: I'm an active Lindy Hop dancer - ok, I have been before covid... - I love dancing and I am really looking forward to when I can visit dance festivals again.)

I had a bad trip and afterward I had anxiety. No anxiety before then.

I don’t have “Anxiety” requiring meds and such—the effects taper off over the years.

Believe me, I know the effects I felt and what it did to me—statistics and external “scientific proof” are not required.

Also, true there are many ways to manipulate people. It’s what you can make them do while they are on LSD that is scary. If you try LSD you will know what I mean—you could walk into a train without hesitation or fear. At least if the other methods are used to manipulate people their underlying emotions, hesitations, and consciousness is intact.

Again, I agree certain drugs should be legalized. And perhaps LSD can be therapeutic in a good way. But, it is also very dangerous stuff—more so than other drugs.

That is my opinion and not based on rigorous research. But I have done a lot of drugs in my day—and I can say if I went back in time I still would have done the natural stuff (mushrooms, cannabis) but never would touch the man-made chemicals.
It certainly helps that we have the last 30 years of mistakes to learn from.
It may be typical but it is a useful counterpoint to the idea that markets are efficient for consumers. If markets “worked” as so much propaganda insists they do, banks would rush to increase interest rates, and gas stations to cut prices, when market conditions allow in order to better attract customers. In reality market inefficiencies allow predatory behavior (it takes time for consumers to notice interest rate changes; gas stations can practice soft informal forms of collusion). Free market and anti regulation advocates like to deny or avoid discussing this.
One benefit dance has is being low risk, especially for someone that might be in a partially compromised state.
You could still change to LTE on your phone. Just sayin...
Don’t put down to malice that which can be explained by incompetence.

It’s generally a happier way to live and view the world.
Despite being a fan of Goethe's writing and poetry, I somehow never knew about his work with color. I find this area fascinating, especially how it relates to language. What an interesting read to find on HN.

Where you're from generally makes no difference to getting a green card, unless you're trying to get it through the green card lottery, in which case certain countries are disqualified. But if you're doing it through employment, you need to fit into one of the preference categories (https://www.uscis.gov/green-card/green-card-eligibility/gree...).

I live in the mid-west. Most of what I said in my previous comment is probably not very applicable to NYC though!
Dang, I thought we had discussed this: moderating based the mere risk of controversy is how echo chambers form. Doesn't this go against HN's guidelines of fostering interesting, civil discussion?
I've been a dancer for 30 years, of many forms.

The best way I can describe dancing to non-practitioners is that it's like playing a silent, wearable musical instrument that demands attention from your entire body.

It is not like playing a sport, except perhaps if you do it competitively :-)
>There are no novel ideas without a source.

All sources are ideas in itself and If all "ideas" under your definition have a source, this means every source also has a source because they are ideas themselves. By induction this leads to the existence of ideas with an infinite chain of sources... Which is impossible.

By logic, the Chain must terminate at an idea without a source. Thus it can be said that:

All ideas are built from an idea without a source.

We call this an "axiom" in mathematics.

The exception to this rule is the existence of a cycle in this chain:

An initial idea that refers to another idea that refers to the initial idea as its source; A closed loop.

However, we as humans tend to shun these cycles as we call them "paradoxes."

What the poster means by "novel idea" as opposed to "idea" is the terminal idea at the end of these source chains.

In short, the inception of all "novel ideas" begin without a source. Again, we call this "novel idea" The axiom or the assumption.

The strange thing about the axiom itself is an entity that "bans the distinction between truth and fiction" and is ironically the foundation of all human logic.

Another word for this is a "paradox" something we both shun and use as the foundation for all human logic.
You outsource it. Like I’m not on FB but my wife is.
why?

EDIT: I think that the 10pm/midnight cutoff point is less about some danger switch getting flipped at midnight and more about there being some well-defined point where CPS need to step in and ask the parents why their children are unsupervised. If it's vaguely defined it makes enforcement of the law more difficult or will cause the law to be unevenly applied (something like poor kids get neglected because CPS can't prove neglect).
Except we’re not talking about companies, we are talking about the actual app in question. The app is called instagram and it is separate from another app called Facebook by the same company.
I should also have said that this competing idea was raised literally in the very same Burton Bloom 1970 paper that the more famous filters come from.

Analysis of speed these days (where a single main memory hit is thousands of superscalar dynamic instructions) is tilted differently than it was in 1969. Still, even back then Bloom's own original paper had a footnote qualifying his superiority conclusion as dependent upon memory system assumptions. Beats me how this gets lost. Call it "The Bloom filter mystique".
"Virgin Media’s Marketing Team" for sure, because it's their responsibility to test if their message works. There always will be some buggy software around. It could be feature phone, iOS, Windows Phone (devices are still alive), some tablet with SIM or whatever. It is "Marketing Team"'s responsibility to test if their message can actually reach their customers. Everything should be tested. Always.
Since no one has explained it,

The joke is that he is enjoying local brewers so much that he has gained a lot of weight or has some behavior changes due to increased alcohol intake that bother his wife :)
Nice, been 'raving' for years ;)
>To access Reddit you first need a device AND an internet connection AND you need to be literate.

That's an incredibly low barrier. Homeless people are merely people without homes. Compare the cost of a smartphone and mobile internet to how much you would have to spend on rent to cease being homeless. Let's be extremely reckless and just get an iPhone Xs plan for $60 per month including 20GB worth of data. Even the most expensive option is basically less than 10% of my rent. It's easy to find a prepaid smartphone for $200-$300 that will be equally useful as the iPhone, last you at least 6 years and you can charge the balance up by going to a retail store where you can simply pay with cash.

Although I agree that literacy is priceless it's probably not 100% required with a modern smartphone. You can probably use voice commands and watch videos and listen to podcasts.

>This doesn't even touch the surface of what real problems most of the world in poor countries face.

Poor countries only have themselves to blame. The real problem they face is primarily the result of government incompetence or corruption and conflicts between countries. In a globalized world prosperity is coming to everyone that is embracing it.

Slums are the result of the poor showing their willpower to pull themselves out of their misery but they are usually prevented by government policy to make their dreams come true. Tent cities in San Francisco are truly worthy of being called slums because their root cause is exactly the same.

I personally think your argumentation is weird. (Don't feel bad about this) You classify homelessness in the US (or any other developed country) as a "First World Problem" because it does not compare to "true poverty" experienced in "truly poor" countries. The implication is that we should be glad that poverty in the US is this "insignificant" but therein lies the paradox. If it's truly insignificant then why should homelessness/poverty as we know it exist at all? People somehow think that the poor should suffer as if they have received a punishment that they badly deserved but yet the poor should also feel good about themselves because it could be even worse. All of this is merely a justification to not help anyone. What you are doing is the same thing you accuse the author of doing. The author isn't thinking about people poorer than her but what about you? Are you thinking about people poorer than you (such as the author)? No, you aren't, not even after reading one article from a poor person.
This is just the TikTok clipboard problem all over again. Reasonable developers who've dealt with initializing APIs that are complex or not their initial forte will make decisions like "initialize the camera on app open if we need it and then pull data from it later." It's pretty trivial to make that mistake.

I wouldn't even be surprised if this is part of Instagram having a goal to make opening camera capture really fast. They've done very similar things intentionally before. [0][1]

I work with cryptographers daily and crypto is magic, and the amount of variables you need to consider when working on crypto systems is so large and varied that it takes a team to succeed. You should not roll your own crypto because your recruiting is not good enough to gather that team around you.

The only thing from that article that I agree with is that gate keeping is bad. Crypto is so hard that we need more cryptographers to help us, not less.
