I had a similar experience when doing my first serious work in a compiled language. I found and reported a compiler bug in double-precision division (in a commercial C compiler). It took me years to stop blaming the compiler for my bugs.
I've skimmed over it and didn't see if there's a compelling reason to use this over CBOR, or vice versa.

Anyone have any insight?

It's for a specific library of course, but there are some numbers here:

https://github.com/neuecc/MessagePack-CSharp
I believe a more standard approach is to say

0 := {}

1 := {{}} (= {0})

2 := {{}, {{}}} (= {0, 1})

3 := {{}, {{}}, {{}, {{}}}} (= {0, 1, 2})

n+1 := {0, 1, 2, ... n}

This has the advantage that the numbers are equal to the cardinality of the sets that define them. In the construction you gave (which I agree is conceptually easier), the cardinality of 1 is 0, and then the cardinality of every greater integer is 1.

A cool feature of this version is

x < y := x ∈ y

I am a Bitwarden user (three years paying for premium) and while I like it the desktop app isn't as feature rich or as smooth to use as 1Password imho.

It lacks biometrics support for one which is something I wish they would add but I believe as it is an Electron app they cannot do so, at least not on macOS.

The iOS and Android apps are decent enough though. They support Touch/FaceID and the Android equivalents. With the exception that the iOS app has "Live Sync" (i.e. push notifications to sync the vault when a change is made elsewhere) but they never work. I recently made a post about this on the Bitwarden support reddit [0] but had no response from the developer there or on Twitter which is a shame. Live Sync works fine on Android though so it is clearly an iOS issue only.

If 1Password were cheaper, or if my needs were more complex, I would switch away from Bitwarden but as a home user it is "good enough".

I've long struggled getting Emacs to interop with all things Mac, and so happily pulled down Spacehammer to give it a shot. It seems snappy and generally like a Good Idea, but whenever I try one of the configured Emacs-related commands, it briefly pops open a new Emacs GUI window and then immediately closes it. Nothing useful seems to come from Messages or Warnings.

I don't suppose you've run into & dealt with this or similar, or have any ideas? I'd love to use Spacehammer.

Your answer doesn't explain to me how it's meaningfully different from boosting and bagging.

Boosting finds the "hard" datapoints by figuring out what the early weak learners fail on, and then trains further weak learners by boosting the weights of those "hard" datapoints in the training data. Sounds just like what you described

How is the method used by the "military industrial complex" meaningfully different?

Genuine question - is it dangerous to memcpy X bytes that we know must be interpreted as, say, an integer?
Walkthechat, without saying too much, be careful with that site (and it's so-called data). Double-check any facts before you trust it.
But there's a nuance there that I think needs clarification: is the right to not be discriminatorily singled out or a right to be provided access to infrastructure in all circumstances?

I think the right has to be the former, and general, nondiscriminatory restrictions would be OK. I posted in another comment that state governments regularly shut down roads and other infrastructure due to public safety concerns. I think closing roads in a lockdown could be done under similar authority.

The latter, to be provided access to infrastructure in all circumstances, is kinda nonsensical when you think about it. For instance, it would mean everyone had a constitutional right to drive through roads that have been closed for construction, which would be ridiculous.
I don't ever machine parse it, but it can be useful for manual discovery if you get an API that isn't super well documented. I think I might generally prefer Swagger, too, but not everything is implemented in a language that has a library like that.

At the end of the day, though, I'd seriously much rather just have a halfway well commented *.proto file. Work smarter, not harder. It's just that I won't recommend that for public-facing APIs because GRPC isn't universally well supported, while JSON over HTTP is.

Some surely do, but his supporters, in general, are less likely to believe that Russia had a significant impact on the 2016 election than their more centrist counterparts in the Democratic Party (who were surprised that Hillary didn’t win by a landslide and struggled to come up with an explanation).

Another piece of the puzzle is they describe consumer electronics in very generic terms. So the real answer is "it depends". A while back I saw an iMac on the show. I had been looking at that exact model and new all the various price points it could be, but they didn't give enough information to narrow it down at all. It was just "an Apple computer" and then the detailed description labled it "an iMac".

Please be careful not to generalize when proposing solutions, because their is not the depression(1): Depressions can be caused by very different things, can cause somewhat different symptoms and certainly can be solved using very different approaches. I met a lot of of depressed people, most them got out of them with different approaches (meds, therapy, changes in their environment).

I myself tried the approach mentioned, during therapy, without any success: Achieving something just didn't produce any positive effect for me. Then I got treated (as last resort) with ECT, my condition improved temporarily, and suddenly, within the same therapy, I started to feel an effect and was able to stabilize.

In short: Propsing "Do <x>, it most likely will help you" is not a good idea, as it is quite depressing for the depressed (at least for me it was). Maybe it's better to say sth like "Try <x>, maybe it helps, if not, there is also <y> or <z>. There is a lot that can be tried, maybe something might help you. "

(1) A doctor explained it to me like that: "depression" is more like a term to group together conditions that partially share symptoms, and that is it basically used for handling the insurance stuff etc. For treatment (at least for severe depressions), the term is too rough to be useful. E.g. a lot of severely depressed people also show symptoms of psychosis as side effect.

EDIT: Formatting and reformulated a bit (I think I was too harsh)
We would love to kill it, but that's not really an option right now. To kill it we either need a vaccine or to quarantine every single person 24/7 because we don't know who has it. We don't have a vaccine yet and the other option would completely kill all economic activity. More people would die from lack of access to food, water, and emergency services.
Would make more sense for the elderly and vulnerable, and those that work/live in close proximity with those to be self-quarantined. Makes little sense to apply those measures to the young and healthy, for whom the effects (both symptoms and mortality rate) are similar to contracting flu without vaccine.
Because, between the lines, the level of top down, military like action and trampling of civil rights that is possible in China is likely not possible here without sparking a civil war - making the whole situation worse.

What do you mean by protect?
Actually , I think thats no longer the case.

(Except if you want to use JSON for configs, which a strongly recommend against for a bunch of reasons including missing support for comments).

I mean by now nearly all times you send thinks over the wire they are ecrypted or at least compressed. So inspecting on-wire messages without "proper" more complex tooling doesn't really work. But if you have already more complex tooling involved there is no reason why you need to be able to read the raw message, it could be just converted on-the-fly into a readable format.

Same applies for application development when e.g. logging, you always do some formatting/conversion when logging some data, so not a problem to convert msg-pack to a human readable format. But then today logging of e.g. servers should always go to some form of log server which does add features like search ability by indexing the log and similar. So no problem to have a msg-pack viewer there, too.

Honestly I believe the only reason human readable formats made/(still do make sometimes) sense was due to limited tooling sometimes caused by server limits in computation power on the developers system. And the fact that many binary formats are totally over engineered making handling of them painful. Especially debugging of slightly corrupted data. Which isn't the case for MsgPack.

Nothing IMO but a lot of folks argue that using immutable state and functional paradigm results in more predictable applications.

Not sure if all this immutability talk in the JS community is parroting because "it's what Facebooks does" or what. Maybe it makes sense once you are building really big front end projects but personally I've never had an issue with mutable state in small to medium sized projects (less than 50k LOCs). Although I admit I've never worked on a Facebook-scale kind of project.

This is actually not accurate. The payments loop is entirely closed in an SE-based system. There are keys loaded on the enclave in manufacturing that come from the card networks, they encrypt tokens on the way to the SE and they can only be decrypted on the SE itself. Then during an actual transaction there is another encrypted exchange over RFID and again the encrypted blob is generated by an applet on the SE.

The United States of America in the same list as India, North Korea, South Korea, Somalia, Angola, Liberia, and Guinea-Bissau. Some of these countries are poor or low income. The USA isn't one of them though. I'd be ashamed of my country.

In The Netherlands, an entire [large] province (North Brabant) has been ordered to stay home if they have anything resembling illness. People are asked to work from home. Children can't go to school. Still, working from home is better than nothing.

Also, some people are in quarantine. The people who have COVID-19 but otherwise don't have it severe can stay home, in quarantine, instead of in the hospital.

One thing I wish I knew way earlier is that COVID-19 victims rarely suffer from a runny nose. I recently got it from Our World In Data [2], it was linked here on HN. I did not read about this in our local media, sadly.

Strange study. Maltodextrin is basically pure glucose, it hits the bloodstream right away and in a very high concentration. This is why it is used in "gainers" bodybuilders take after hard workouts, to trigger insulin response and replenish muscle glycogen.

Sucrose has to go through the liver first, so its release and concentration will necessarily be much lower. Not as low as for fructose, but lower than for maltodextrin. Its half life will be longer as well.

The point is, the two sugars aren't even using the same metabolic pathways, and yet they compare them as interchangeable. WTF?

Whenever I wonder this, I always think back to wargames’ example of phone phreaking. The answer seems obvious: early hardware/software was insanely easy to exploit because hardware/software security was not a thing. It was trivial to use features in a malicious way. We’re currently in an arms race because eventually society decided it wanted computer security.

That’s not to say systems were all insecure in the past. You just didn’t trust computers to be secure.
I am facing a similar issue with my aging parents. They are both 70+. They both get respiratory issues every year. My Mom in particular is convinced she is healthy and doesn't need to worry about it. I understand why she is resistant towards the notion that she is vulnerable (I have similar issues confronting my own aging, and I am roughly 40 years younger), but it still pains me to discuss this with them. I lose my patience, which isn't helpful. I am growing more and more fearful that they will put themselves at risk, become infected, and then not survive when the hospitals are overwhelmed.

If anyone has any ideas about how to communicate about this with them, I am all ears.

Thank you! I've been pretty obsessively thinking about meta-science issues around interpretability for the last six months or so. :)

A notable researcher privately told me that they think all interpretability research is nonsense. As someone who's dedicated the last six years of my life to this field, that was pretty uncomfortable to hear. But I think it's important to pay attention to, because I think it's actually a pretty common, unspoken view.

As a result, this has been on my mind a great deal. I think two important questions are:

(1) How can we surface the disagreements that are leading to such divergent views between different members of the research community? (Especially when people are generally too polite to say that they think something is total nonsense.)

(2) What would a more epistemically stable foundation for interpretability look like?

I'm not sure what the right answers to these are, but I think they're important to discuss.
We're already most of the way there with self checkout. My local Home Depot only has self checkout now, with 1 person managing something like 10-15 registers. They left the person running the "Pro"/lumber checkout area, but that area looks like it's being set up for self checkout too. They also seem to have removed the Garden Center checkout.

I'm not saying it's a great thing, just that the jobs Just Walk Out will be replacing are already being replaced by self checkout.
Except that the discussion is common ... it's all about the concept of flattening the curve to reduce the peak and thereby not exceed the capacity of the health service.

It's the same data, it's the same idea, it's the same argument, but from a different source.

It's also all now all over the place ... I could find 8 or 10 different sites to submit, all with the same message. Is it useful then to have 8 or 10 discussion on HN all hacking over the same ground, all making the same points, all having the same "insights" and disagreements?

I think not, and that's why I linked this submission to the existing discussion.

The new Tesla roadster coming soon(TM) does 0-60 mph in 1.9 seconds, and the quarter mile in 8.8, which is staggeringly fast even by ultra car standards. People that spend years and hundreds of thousands of dollars on their dedicated drag car never get that fast. I don't believe there's ever been a production car that runs in the nine second range, let alone into the eights.

I believe with EVs, traction is not as much of an issue because the computer can adjust the torque output 1000 times per second, unlike an Internal Combustion Engine which takes eons to react and change it's power output. Obviously off the line it is, but certain as you get moving more you can dump a lot of torque into sticky rubber.

Tesla are having a "battery day" soon, and I for one suspect their new batteries (maybe just for the new Roadster, maybe for all their cars) will be some kind of hybrid capacitor, or at least have some of their capacity does that way.
