Hi! Author here. You are absolutely right, and I called out a lot of those limitations in my original design doc.

http://cushychicken.github.io/bfunc-design-doc/

I'm just starting to get to work on the second version of this board, and I'm planning on addressing all of these in that design.
Scientists identify gene responsible for butterfly’s dazzling structural colours
This is a bold assertion, and one that is not obviously true, especially in cases like 0.999... and 1.0
I reject any argument which justifies behavior because it makes someone money that they otherwise might not. Captalism does not justify a lack of ethics.
I thought this also. SQLite as a default would have been nice.
The “data presented by the two doctors” has obvious reasoning errors to anyone who has taken even high school math.

At this point, how can you look at the number of people who died from COVID-19 in just the last month in NYC and claim this is no worse than the flu? https://www.nytimes.com/interactive/2020/04/27/upshot/corona...

The last flu to cause such a severe spike in mortality statistics was the devastating 1918 Spanish flu. Even the Asian Flu and Hong Kong Flu pandemics didn’t do this.

Edit: corrected the Spanish flu year. My bad :-)
Yes. British people have already paid the lion's share of what is cost to produce these images, ie getting the artifacts cleaned and into a place where they can be easily photographed. We should be able to use it to generate revenue, since this is further taxed anyway. Seems like a wasted opportunity.

Ironically many works of the British Library are out of copyright abroad, but remain in copyright within the UK.
If it's really so great for the high income students, then maybe the schools there should be shut down permanently so the money can be redirected to where they are necessary.
I think your arguing against some position that I am not even suggesting.
You think im saying "if we took the money of billionaires we would have enough to give the whole country 1k/month forever"

Im suggesting that there is enough money when you think in totality so this is merely a question of how comfortable you are with redistribution. Your saying 2.5 trillion annually; ok thats only like 12% of GDP.
It is also completely logical that in the 21 century that only about 10% of value generated is enough to keep everyone fed clothed and sheltered.
> This is why, after decades of controversy, Google Translates still renders the gender-neutral “they are doctors” in German as “sie sind Ärtze” (masculine) and “they are nurses” as “sie sind Krankenschwestern” (feminine). Google Translate was not programmed to be sexist. The corpus of texts it received happened to contain more instances of male doctors and female nurses. [...] BriefCam’s spokesperson added that they used “training datasets consisting of multi-gender, multi-age and multi-race samples without minority bias,” but declined to provide any evidence or details.

Okay, will we at some point admit that we want machine learning algorithms to be able to interface with symbolic rules rather than pretending that everything is a data issue as if we're living in the era of 1930s inductionism? It's clear that the misgendering issue here is not a stochastic one that ought to be solved by 'balancing out' data, it's that we want to impose strict linguistic rules and constraints on a system in a clear manner.

There really needs to be more work done in AI that makes it possible to interface with the models we built rather than trying to reframe everything as a data problem and then shove it in some end-to-end black box and then hope that whatever comes out at the other end is correct.

The automated systems used in the article are supposed to make judgements about "Detection of body movements that constitute assault." This requires genuine understanding and high-level capacity to reason rather than just pixel-based inference from some camera.
Amazon.de does free delivery to Sweden, but it is not next-day of course.

To me the idea for ordering toilet paper online is a bit foreign. In order to collect the package, I would have to go to my local store, where they already sell toilet paper.
Uh, Linux and its derivations drive over half of the computing power in the world, yielding insane productivity gains for people of all classes, races, ages, and geographic locations.

I think that speaks for itself.
Refund and replacement aren't always easy depending on where you live or which amazon firm it is (different countries, different contractor company). But that's not even the point, wasted time and headache is not something many want to deal with.
This looks much nicer than the wasm2c output for that binary. I compiled it with `clang wasm.c -c -target wasm32 -O2` just like in the instructions (I'm on LLVM 10), and used the latest wasm2wat with `wasm2wat -f wasm.o` and got this instead:

(module
(type (;0;) (func (param i32 i32) (result f32)))
(import "env" "__linear_memory" (memory (;0;) 0))
(import "env" "__indirect_function_table" (table (;0;) 0 funcref))
(func (;0;) (type 0) (param i32 i32) (result f32)
(f32.add
(f32.add
(f32.mul
(f32.load
(local.get 0))
(f32.load
(local.get 1)))
(f32.mul
(f32.load offset=4
(local.get 0))
(f32.load offset=4
(local.get 1))))
(f32.mul
(f32.load offset=8
(local.get 0))
(f32.load offset=8
(local.get 1))))))

wasm2c (also from WABT) returns this thing: https://paste.linux.community/view/7877995f

Reduce activity as little as possible (if your local health care is overwelmend, that is a total lockdown), and keep watching the curve. If you get spare health care capacity, free people a bit, if that capacity fills-up put restrictions back.
Things Tech and Real Sourdough Have in Common
We need a new plan. Every single job before-covid (BC) is not coming back. Even if we opened the country at 100% tomorrow not every job will come back. There’s a paranoia that’s set into the American psyche that will take years to adjust.
American living in Vietnam right now.

The first part of your post is true.

The second, is in my opinion, completely false.

As others have mentioned, the government is incredibly diligent in tracking the virus. And why shouldn't they? They were freaked out by SARS in 2003 and as a growing 3rd world country, they simply cannot afford to have the virus spread.

Also, if one person gets the virus or one person is placed in quarantine in Vietnam, it's all over Facebook and shared. The government can't hide shit when it comes to the virus.
> Health savings accounts doesn't seem that great though - I don't know if I'll ever have health issues so if I'm socking away $x00/month I'm removing that from the economy betting against my health.

A pretty safe bet, seeing as most people's health gets quite a bit worse over time.
In the article:

> Zoom selected Oracle to expand its cloud, bypassing major industry leaders Amazon Web Services, Alphabet’s Google Cloud Platform and Microsoft’s Azure Cloud.

I guess GCP isn't significant enough to be in the headline
Except the fact that XR2206 and all similar analog sig-gen-on-a-chip devices are obsolete and essentially unobtainable as raw parts. Ok, you can buy cheap chinese "arduino-like" module that purportedly is built around such chip....
> the availability of employer-provided health insurance seems to disincentivize price discovery.

That I certainly agree with.
Sorry, not a direct answer. You might want to look into Lions Mane mushroom extract. There is a double blind study out of Japan that shows nootropic properties (regrows nerves). Good luck to your father.
As long as consumers trust Amazon and don't trust the merchants, it doesn't matter. They have to use Amazon anyway. This is presented as a strategic problem for Amazon, but it isn't.
That statement is based on:

> First hopefully we can agree that if we have two real numbers x and y that are not equal then we have a number z, such that x < z < y. The easiest example is z = (x + y)/2.

It's one of the properties of the reals and rationals that if two numbers aren't equal, then there are infinitely many numbers between them. It doesn't work with the integers, 2 and 3 aren't equal, but there's no integer x, such that 2 < x < 3.

So if we say 0.999... != 1 then that means 0.999... < 1 and then that means (0.999... + 1) / 2 is a number different from 1 and different 0.999... but that lies between them.

But this is modern mathematics. In the past mathematicians dealt with "infinitesimals", especially in the early days of calculus, but I think they were discarded because they were confusing and also not necessary in favor of limits. This is where I think where some of your confusion is coming from. Infinitesimals don't exist in the real (and therefore rational) number space, but the concept exists for other "weirder" number systems.

According to the wikipedia page "This repeating decimal represents the smallest number no less than every decimal number in the sequence (0.9, 0.99, 0.999, ...)"

The clearest resolution to "if you interpret 0.999... as the "biggest possible number below 1"" is that in the reals and rational this concept doesn't exist. There's no biggest number smaller than x and ditto for smallest number bigger than y. (The distinction from the wikipedia definition is the difference between < and <=, <= exists, but < doesn't)

It's similar to saying you can't divide by 0. Sure in some cases you can define it, but doing so causes many issues and costs you so much that it's not worth it.[1] Another example is 1 not being prime, there's no reason for it not to be prime, but it's just much more convenient to say arbitrarily that it's not prime.[2]

The other thing that might confuse you is a proof by contradiction, I know it certainly confused me the first few times I saw it. I'm happy to help you if this is tripping you up too.

> I'm slightly embarrassed I don't know more mathematics, but I'm trying to learn some more...

No problem, we all start knowing nothing :)

Use GraphQL instead of SQL to fetch complex related data from your DB in GO
The idea behind this library is to build an alternative way to query databases using GraphQL instead of SQL. Unlike with direct SQL or an ORM you don't have to write all the steps required to get the data you want in the structure you need, instead just describe it with GraphQL and you'll get exactly the data back.

package main

import (
"database/sql"
"fmt"
"time"
"github.com/dosco/super-graph/core"
_ "github.com/jackc/pgx/v4/stdlib"
)

func main() {
db, err := sql.Open("pgx", "postgres://postgrs:@localhost:5432/example_db")
if err != nil {
log.Fatal(err)
}

sg, err := core.NewSuperGraph(nil, db)
if err != nil {
log.Fatal(err)
}

// And here's the GraphQL query to fetch posts, comments, author, etc
query := `
query {
posts {
id
title
body
comments(limit: 5) {
id
user {
id
name
}
}
user {
id
name
}
}
}`

res, err := sg.GraphQL(context.Background(), query, nil)
if err != nil {
log.Fatal(err)
}

fmt.Println(string(res.Data))

}

>> They had a part in it, but it's the people/ecosystem that creates the wealth, not an individual. Linus didn't create all the distros. He didn't install it on all the servers around the world.

One is a much more replaceable skill than the other in this equation. That's why Torvalds has contributed more to world productivity than most.
>it’s a struggle to get them to pay attention during the zoom class

Given the attention a lot of adults pay during boring Zoom calls or virtual events that don't grab their attention, I would say the elementary school children are in good company.
I doubt the Fed has the legal authority to impose employment-related restrictions on companies.
The Hubble has a launch mass of 10000kg and has a mirror with a 2.4m diameter and 4.525 m^2 collecting area. The ELT has a diameter of 39.3m area of 978 m^2, that is 216 Hubbles.

The target cost of getting stuff to LEO using Starship/SuperHeavy is $2m per 100000kg, or $200k per Hubble. It would only cost $43 million to launch the light-gathering equivalent to the ELT. Now, $20/kg to LEO is very optimistic, but even at 5-10x that rate, a more believable $100-200/kg, that would still make the launch possible for 200-400m, which is roughly the cost of a Delta Heavy launch. Scaling this up, a 100m telescope (The OWL) would be 1,735.69 Hubbles and cost $350m to launch at the optimistic price, but still less than $3.5B at the believable price.

Basically, if Starship is successful it could have a dramatic effect on astronomy. 216 Hubbles may sound a bit insane, but mass producing them would drive the cost for each down considerably. Without the atmosphere, you don't need the fancy laser-actuator correction mechanism, and you certainly don't need to fight local activists for one of very few locations worldwide where you can plausibly put these things (AFAIK, there are only 3 such locations worldwide - Canary Islands, Cerro Amazones and Hawaii). Not only that, but if you had a constellation of Hubbles, they could be spread out and use interferometry to construct a telescope larger than the Earth (this is the technique that Event Horizon Telescope used).

So the question is, is it possible to design a standardized, flatpack hubble-sized mirror+cam sattelite and pull it off for the price of a regular telescope? At ~1.2Eur for the ELT, that would imply $45m per "hubble". Seems doable.
Unless Oracle is doing it for free, I see little reason to go with them
What about the eventual vaccine?
This may come as a shock to you, but I didn't have to be working a job at the same time.
I work for SAASPASS which is an Identity & Access Manager (IAM) which has a credential provider with 2FA for Windows computers, including MacOS and Linux computers. There is also an RDP for computers with multi-factor authentication. You can even Remote Lock or Remote Unlock with 2FA your computers. This is all configurable by the admin.

SAASPASS is also an Identity Provider with a passwordless architecture built on a zero-trust framework and can be used to manage all your users, employees and devices. There are over 100 thousand pre-built integrations. There are more pre-built SAML integrations (over 1700+) for the Single Sign-on.

SAASPASS can be integrated with Active Directory or be used as a Directory Service as well.

I'm not against the idea of voter ID. But a well-intentioned voter ID law would make ID easier and cheaper to obtain. It would set up ID registration at banks, post offices, libraries, courthouses, city halls, senior centers, college campuses, churches or other religious/community centers, workplaces, school gyms, supermarkets and convenience stores, gas stations. Make it as easy as buying Girl Scout cookies. Heck, let Girl and Boy Scouts get merit badges for volunteering to take pictures - with adult supervision even a 10-year-old can handle a camera well enough to take an ID picture. Maybe even have a person who comes to your door to take your picture, if you're physically disabled - contract it out to Uber or something.

> Sure, there's opportunity cost to everything. What do you suggest we do about it?

When it comes to voter ID...reduce it? Make it as close to zero as possible? Is that really so crazy? If we care about free, fair, and secure elections, they're worth investing in, right?

> And not just on this issue, but filing taxes, marriage licenses, etc.

Ditto. Tax filing shouldn't cost hundreds of dollars and hours of work.
Thanks! I'll make sure that feedback gets some time in front of the relevant product folk.
Well, here you go, Zoom disruptors - they just tied a lead weight around their neck, time to go to and eat their lunch.
> it's really more like shopping at a bazaar, since really their website is almost nothing more than Ebay in some sense

So, yeah, eBay, Ali-express ... might as well go there.
No one is entitled to free software and should not expect others to slave off and give away fruits of their hard work for free. This entitled communist mentality is unethical.
That's a good question.

Another good question is "Should the nation of Greece and the Greek people be allowed to profit off of pictures that the British Museum has taken of objects that are only in the British Museum because they were pillaged by British soldiers?"

It seems really bad that a nation can invade many other nations and pillage their cultural pieces to squirrel them away in a museum and then dictate to the citizens of those nations what they can or can't do with pictures of the artifacts.

The notion that the British Museum can tell Egyptian citizen what they can or can't do with photographs of the Rosetta Stone is pretty odious.
How far lagging behind is that assessment, or how likely is it that perceived trust is just lagging behind?

Anecdotical, it's wasn't long ago that I was deeply impressed by Amazon's customer service and quality. This has changed drastically, and today I go as far as only using Amazon if I basically have to. Thanks to recent developments (I'd say over the past few years), I now prefer either the manufacturer's website, or shops specialized on the relevant subject. I even get my consumer electronics from Best Buy.

I might be a bit extreme there (or maybe just "further along", depending on how you look at it), but Amazon having gone downhill--from once being well-known for its customer facing qualities no less--is certainly not a new or hot take.
Personally I found LimeLM offering a pretty amazing and sophisticated product at very decent prices. Personally, I would never want to suffer the pain of keeping licensing servers running etc. :-)

In my experience, software licensing will just “get rid of the casual piracy” - but I could never see not having a licensing solution in software work for business...

Beyond protecting software I found it similarly necessary to take down illegal software copies. There are automated tools for that luckily.

Yeah, your software will be cracked sooner or later. But it is not all black and white and there are now really great sophisticated solutions out there that minimize the frustration for paying customers whilst also protecting your IP...
> If we don't have comprehensive audits, how do we know it is not a problem? Eg. How do you know your server is secure if you don't have an IDS?

A few politicians with strong motivations to find any evidence of significant election fraud they can, and holding positions that give them the authority and, indeed, responsibility, to go looking for it have done so, and so far as I know they've all found little enough that I think it'd be fair to round what they've discovered down to "nothing". All evidence I'm aware of is that there's a vanishingly small amount of not-particularly-well-coordinated honest-to-god deliberate voter fraud, plus a somewhat larger but still small amount of accidental illegal voting (I gather this is somewhat easy to do unintentionally if one might claim residence in more than one state) and bad book-keeping or clerical errors. If deliberate voter fraud were a significant problem I would expect these efforts to have turned up far more, even if they didn't find the full scope of it.

> I can't remember the source but one study said there are about 3 million extra people registered in the US (people who are eligible - people actually registered). They may not be acting fraudulently, say if they moved from one state to another, or a different precinct in the state. The 2000 election was decided by 500 votes.

I take your broader point, but do note that the 3,000,000 -> 500 here is comparing apples and oranges, due to the way our Presidential elections work (it wasn't decided by 500 votes nationally)
Oh, ok. If I understand correctly, you mean that there isn't any standard algorithm for handling a sum with infinite terms if you don't include limits.

Well, I do disagree, not with the above statement, but the meaning of "0.9..." itself requires limits, so the discussion can never go anywhere if your assumptions do not include limits.
The subtitle is "do you want to get one to try?", but I can't figure out how I would do that. I might be missing a link or something, but you might want to make the funnel more obvious.

I also have no idea what the specs are; bandwidth, drive, interface, etc., so I am not really sure whether I'd be interested. I would suggest adding a brief summary of the device's capabilities to the top.

edit: just realized that you're suggesting people e-mail you to express interest at the end, but I'm probably not going to go to the trouble of writing an e-mail for the faint prospect of maybe getting a board.
Totally guessing here but I imagine this is a super cheap deal for Zoom.
I missed this the first time, but there are two sets of parentheses in the example. Apparently the first set are like template parameters, and the second are the actual arguments to the function.
I would go further and even say that on HN you see these extremes. People that previously consumed massive, unhealthy amounts of coffee now authoring testimonials and blog posts about how life is better without coffee. People that previously could not go 5 minutes without checking news headlines and Twitter hot takes now authoring testimonials and blog posts about how life is so much better when lived in total ignorance of current events. Lukewarm takes about moderation aren't inspiring and dynamic enough to generate views, upvotes, and discussion. We're always looking for that neat life hack, and "don't do quite as much of X and maybe do a little more of Y" is not very neat.
What's the problem of running node for your developer tools?
We don't know that it's not 10 times worse. Data is confusing and sketchy, but there are many datapoints that indicate that the IFR is over 1%, and maybe as high as 2%.
very cool! my first thought was that it looks way more complicated than a simple joystick/steering control.
Why compare a commercially available top of the line function generator with a hobby project?

Because as soon as you do, you start to realize that you can get quite a ways with commodity hardware. Hence, why I started this project. The research I've done on the frontend of this on what's available in the market suggests to me that there's a niche for something that's a little cheaper, and a little easier to use. I also have a hunch that portability is a nice feature for most folks as well.

(Hi Jacques!)
Thank you! This thread is full of people insisting on something wrong because they were taught incorrectly; an irrational number is defined in terms of integer ratios for a reason.

It's not like those people haven't worked with an irrational base before, either! Radians have an irrational base. When we talk about 2π radians, or 1/4π radians, that's exactly what we're doing.
Minor nit, open source != free as in beer. In FSF philosophy it's not wrong to charge money. It is wrong not to include the source with the customer's purchase.
That was an obvious error in their reasoning.

Not surprising, though.

Idiotic (and, yes, such an error IS idiotic) fumbling with statistics is displayed on a daily basis.

It doesn't matter what 'side' you are on: idiots abound.

Doomer fallacies:
Charts showing exponential growth of positives, without taking into account the exponential growth of tests...

Flu-Bro fallacies:
Antibody surveys that don't take into account false positives and make no mention of the expected number of positives in a population (both needed to make ANY sense of the results.)

Doomer fallacies:
No distinction between dying 'with' versus dying 'from'.

Flu-Bro fallacies:
Relying on death counts from the Chinese Communist Party.

Doomer fallacies:
Comparing 'positive' test rates between populations and countries with utterly different criteria for administering tests.

etc.

One thing you can count on, though: You will usually get a downvote on Hacker News if you deviate from the mainstream.
