I was gonna do something involving about 3 different neural nets:

a source separator: taking one audio stream as input and producing a set of audio streams as output.

a segmentation regression neural net: takes an audio stream as input and returns start and stop timestamps of individual samples as output, or alternativey, just trimmed copies of the audio stream

sample classifier: takes an audio stream and then returns “kick drum”, “snare drum”, “voice”, “guitar”, etc

then the pipeline would be like

source separator => segmenter => sample classifier

Hopefully with this I would be able to decompose music into constituent parts, useful for remixing and other kinds of musique concrete

I expect that the results with a deep pretrained generic image model + some tweaking with more niche training examples will be satisfactory, but if not it would be a good excuse to experiment with more traditionally seuqnece-oriented network architectures

> During testing I had to shut it off because it became increasingly more complicated every page reload. First it was just one page of traffic lights, but 20 minutes later I was having to click through 5-6 pages of images. This worries me that user's might get pissed off.

Why are you now badmouthing someone else for deleting Spotify over this exact same issue?
Yup, or even ask if you can work the suction yourself. I've done this lots of times with my current dentist.

I hold the handpiece out of the way, and if I feel like I'm drowning, I kinda wiggle it in the direction of my mouth, they make room, and I go in and vacuum things up. If they see the need before I do, they just say "suction", just like they'd say it to any other assistant.

It's no different than holding my own jaw open. If the patient is awake, they're part of the procedure. Might as well make the most of that. And if it means less anxiety and discomfort, which means you're happier and more likely to return, that's a win for everyone.

During one visit, I noticed that the swing-arm lamp had a flat plastic cover on it that acted as a mediocre mirror, and I could see what they were doing in my mouth. As soon as I noticed that, the random shoving and scraping (which always made me nervous as hell) gained context of the work they were doing, and I calmed way down. I ask for the lamp every time now.

Jesus, what’s the point of the comment section on Politico?
I think a tax is any compulsory fee levied by the state. Even if you generalise the concept to all compulsory fees, I don't think it fits in here. You're free to not use the card brands payment networks, and pay them no fees. You can say that it's not practical to do so because that would severely limit your ability to pay for goods and services, but that's what transactions were like before the card brands innovated the industry. They render a service that provides extraordinary convenience for consumers, that's what you're paying for. It's no more a tax than any other expense that's factored into the margins of the goods and services you buy.

Which self-driving car business would you bet on: One that's sinking most its capital into developing its self-driving technology, or one that's sinking most its capital into subsidizing drivers' incomes, and needs to do so simply to stay alive?

If Uber really, really believed that self driving was such a sure thing for them, their optimal strategy would be to wind down the rideshare business, the food delivery business, and all its other businesses that aren't self driving, so that it could redirect its mountains of capital toward developing self driving even sooner. Because as soon as cars that really can operate fully autonomously hit the scene, it's not going to matter who was incumbent in the rideshare space or how dominant they are. The company with the self driving cars will take over just about as quickly as they can manufacture new cars.

The fact that they're not playing it this way implies that they're not so confident that they're well positioned to be first past the post with self-driving cars. Which means we probably shouldn't be, either.
> Oh, I meant how long after you click the link should you stay logged in for?

That's up to the service. I think for most use cases having the login last 3, 6 or even 12 months is ok and then it would get invalidated early if the user explicitly logs out, they change their email address or the server blacklists the token.

> My bank makes me reenter my password after maybe 1 hour of inactivity for example which would be super annoying with magic links.

1 hour of inactivity is a very very long time for a bank. I think my bank logs me out after 15 minutes or so but I can't remember when that last happened.

Are you really idling for long periods of time on your bank's site? I typically login with a specific purpose. Maybe it's to check my balance, or see if a recent charge / deposit went through, etc.. It's things like that where I'm in and out in 30 seconds, or at most a few minutes.

In both the password and magic link case, you can still re-validate the session without any user intervention as long as they are actively using the site. If there was a legit use case where people's sessions needed to expire after 10-15 minutes of inactivity and it was very common for that session to expire I would re-think the entire user experience and design things so sessions expiring weren't so common because this sounds like a really poor user experience in any case. But if the 0.00001% use case came up where you wanted to torture your users with logging in every 10 minutes, then I would avoid magic links.
I should have posted this earlier.

I usually come to HN for some good analytical cynicism.

But not today. I wish I hadn't read some of the comments on this thread. I get it you disagree, you'd do it better, or different or for xyz reason.

This is a story. A touching one at that, about a hard decision two individuals had to make and the sacrifices they made along the way because of that decision. Ultimately it's theirs to make. If you are ever in this exact situation yourself I don't think you look to an article for advice, but instead consolation.

We were invited in for a glimpse, I don't think we need to criticize these people we don't know. I don't even want to pretend to be able to justify their actions either. I don't know them.
> the 137Cs concentrations were incredibly high, up to 480,000 Bq per square meter in their deepest samples.

But is that high? I don't know. Let's make some uninformed back of the envelope calculations. The energy of the Cs137 radiation is 662keV, let's assume a normal person with 100lb and a surface of 2m^2 (only half get the radiation). In a day this person will get https://www.wolframalpha.com/input/?i=480000Bq%2Fm%5E2+*+662... 48uSv per day. [If I didn't make a huge mistake.]

It's like 5 times the normal background radiation, a little more than the radiation you get during a flight in a plane, less than the maximum permitted radiation dose for a worked in a nuclear plant (when there is not an emergency). https://xkcd.com/radiation/

I was expecting a much lower value, but this is still on the side of the safe level (if I didn't make a huge mistake).
Here in Norway we got Vipps, a mobile payment system owned by the largest banks here, which recently beat all relevant competition.

At the beginning the transactions went through your credit card, but they added (optional) direct bank account access not long ago. They also quickly removed transaction fees for amounts < ~$500, above it's 1%.

They've also added ability to have company accounts, so that you can pay in kiosks, kebab shops or whatever with Vipps. And since they're backed by the banks you can get and pay your bills directly in the Vipps app. They're currently in integration talks with Paypal to make Paypal<->Vipps transactions more smooth.

So yeah, raising transaction fees isn't the first thing I'd do if I were Visa or MasterCard in Norway.
Yes? That's the "why" of the cost, not the "why" of people willing to buy sight unseen. The latter is explained by enthusiasts when it comes to lower end cars, as I mentioned. There are plenty of higher end cars that are even more exclusive than the Type R and RS and sold very poorly, such as the 2017+ GT-R Nismo and the new NSX.

You can't create tools for censorship in China and support a free and open Internet. Those things are completely opposed to each other.

Pointing out the actions of other companies, the good things Google has done, or the fact that they censor content in most countries doesn't negate that fact. Those are just mediocre argumentative tactics to try and downplay a public relations disaster.

We're not even dealing with the same Google from 9 years ago. Here's some good reading for everyone about how Google went out of it's way to protect Chinese dissidents and refused to comply with the Chinese government. Now they're doing the opposite:

It does when the defining properties of a company town include not being able to easily go elsewhere, and it's trivial to walk/bike/drive/take public transit from the 4.9 acres currently under consideration to the rest of Toronto.
Is this purely for software development/engineering or does applied research still qualify?
Sure, but neither have a guaranteed cash signup bonus. They have guaranteed first month earnings and bonuses per ride.

Uber trying to raise it's fees is an invitation for someone else to jump in with lower fees and compete. You don't need any kind of national reputation, taxi companies never did. You can just compete city by city.

That is lack of pricing power.

It seems that every "writing advice" article or blog entry posted to HN is laden with errors in grammar and usage. Ego without competence is a bad look.

Notes to author of this one in particular:

1) second sentence: drop the comma after "education"

2) second paragraph: drop the comma after "time"

3) third sentence: need a comma after "colleagues"

4) third paragraph opens with a horrible run-on. Quit the first sentence after "essay", then rewrite the rest as a separate, correct sentence.

5) This is followed by a seven-line monstrosity that should be taken out and shot.

I gave up at that point.

Readers, I suggest you not use this as a model to follow. A random pile of clauses does not make a sentence. Commas are not mere random decorations. Using dashes to bracket discontinuous thoughts renders the entire sentence unreadable; to quote WikiHow, "Keep in mind that the rest of the sentence should still flow naturally as if the dashed material were not there." Use semicolons to separate clauses that are complete sentences without a conjunction.

etc.

etc.
I interned for SNC Lavalin Construction in my undergraduate, and a finance guy gave a presentation where he literally laughed out loud in this evil way about how much money SNC was going to make out of it and what a stupid deal it was for the public.

Nobody seems to have read this article although many people seem to identify with the topic because of their own suicidal feelings. I found the article very moving and I learned a lot about suicidal illness. The article is brutally honest. I understood how it could be that a person would not think about the pain their suicide would cause. I appreciated the amount of hopelessness and pain the author was in. One thing that is clear is that his pain is his mother's pain is his sister's pain is his family's pain... It's a large and complex family system, that has beget this suicidal person. It gave me a lot of compassion.
>Look at how fast the Chinese are building them, or how fast e.g. the French or the US were at building them in the 60s and 70s.

"The country [China] has the capacity to build 10 to 12 nuclear reactors a year. But though reactors begun several years ago are still coming online, the industry has not broken ground on a new plant in China since late 2016, according to a recent World Nuclear Industry Status Report.

Officially China still sees nuclear power as a must-have. But unofficially, the technology is on a death watch. Experts, including some with links to the government, see China’s nuclear sector succumbing to the same problems affecting the West: the technology is too expensive, and the public doesn’t want it."

https://www.technologyreview.com/s/612564/chinas-losing-its-... (China’s losing its taste for nuclear power. That’s bad news.)

> That it takes so long now in the west is because we're not building enough of them, thus losing the advantage of experienced workforces and inability to leverage mass-manufacturing of standardized designs.

Can you provide evidence that the cost of nuclear would be comparable to solar and wind if built at scale?

> It's also slow because of onerous safety regulation seeking to make nuclear too safe, when we consider the result of a slowdown in commissioning of new reactors, thus increasing the reliance on coal killing way more people than if we were to hypothetically mass manufacture relatively unsafe reactor designs from the 60s today.

I'm unsure you can sell nuclear to the public or politicians as "it's expensive because it's too safe". It's unlikely we're going to relax safety regulations when cheaper alternatives already exist (solar, wind, natural gas, storage). We're not increasing our reliance on coal, we're temporarily increasing our reliance on natural gas (which is driving coal and nuclear out of business).

EDIT:

"but pointed out that it taking anywhere near 20 years to build a nuclear power plant is clearly off by an order of 4x at the very least."

I’d prefer nuclear reactors not be built in the developed world to Chinese standards.
The internet does not work on top of DNS. DNS works on top of the internet. Nothing about IPv4 was circumvented here, and IPv6 is even built to not need/use DHCP at all.

There is no mandate or expectation that all DHCP clients always use the advertised DNS settings. If there was than alternate DNS services like 1.1.1.1 or 8.8.8.8 wouldn't even exist in the first place, as your ISP would be in complete control of your DNS settings unless you splurged for a static IP.

The cast client decided to use its own DNS settings as many clients do - you can override the DHCP settings on just about any general purpose OS, for example. Even though they are DHCP clients. Do you call Linux allowing you to specify a DNS server as "circumventing how the internet works at a pretty basic level", too?
What's proven about PPPs is that the government always overpays and always shoulders all of the risk anyway. So there's not even the slightest benefit to the public, it's just a way for politically-connected companies to milk the public for free money.
For the most part, a taxi is only better when I'm at either an airport or a hotel. Otherwise, I far prefer Uber/Lyft because it's on-demand, no cash needed and don't have to explain my route or destination.

It's perfectly okay to tell someone to buy a cheaper car or one that's better on gas. Car owners spend thousands more than they need to commute to work.

The Model 3 sits alone in its own market segment at the moment. Buyers know exactly what they want because there's literally nothing else to want without spending significantly more. The i3 is a joke, the Model S and Model X are significantly more expensive (even with the Model 3's currently high pricing) and the rest of the "competitors" are hybrids.
You didn't have to try to be nice and then just push Jesus like that. I mean there's at least a handful of other religions that would go in its place just as fine, but the person you anwser to already gave you clear directions regarding religions, so why push harder?

>It's probably a symptom of death these days in developed countries being so rare.

In what sense is death 'rare'?

Last time I checked, every single person in every single country - developed or otherwise - will die.

The percentage of the population that dies each year, I would bet, is higher for developed countries than developing.

As a user, I love that Firefox has their own root store. It tends to be more up to date, and have higher standards in some circumstances.

As a sysadmin, the enterprise policy that came in 65 [0] was a "finally!" moment. Until then, Firefox was an incredibly irritating little special snowflake. It's still a special snowflake, but a little less annoying.

For comparison:

According to Wikipedia, granite contains 1-20 ppm of uranium [1]. One gram of natural uranium is about 25,280 Bq. Hence, one ton of granite is somewhere between 25,280 - 505,600 Bq.

In other words, if a beach is made of eroded granite, its radioactivity will be between 25,000-500,000 Bq/t: assuming the sand is more than a feet deep, I think it's safe to assume > 25,000 Bq/m^2.

[1] https://en.wikipedia.org/wiki/Granite

> Some granites contain around 10 to 20 parts per million (ppm) of uranium. By contrast, more mafic rocks, such as tonalite, gabbro and diorite, have 1 to 5 ppm uranium, and limestones and sedimentary rocks usually have equally low amounts.

You are mistaken for what google wanted to do. They are not "building houses" or "transportation" or "factories"

Google wanted to harvest data from citizens of Toronto so that they can understand what people do in a city.

It's a part of their data collection goal, and so they asked Toronto "what would it take for you to let us do this" and Toronto said "we need xyz, transport, etc" and then Google came back with the proposal, with the caveat that they are able to collect the data from whoever/whatever tenants move in, from both commercial entities as well as private citizens, and data mine it. It is in no way something Google is doing "for" Toronto. Toronto has enough property developers. The land that this is to take place on belongs to the city, and that's why it's never been really developed.

I would think data of this kind is worth enough that Google should actually be paying the city. At least then there's a proper exchange.

I would also welcome it if the city opened it up to a proper bidding process to let others put in their vision as well.
(1) Low margin is probably OK given the enormous market Uber/Lyft will share.

And yes, especially after a certain age, you should have a job where a few random $5 charges you don't recognize on your credit card statement are something you ignore and don't even bother disputing.
My recollection was that as soon as anyone - but especially techies - tried Google even once they never went back.

The lack of fresh index surely was a factor but not sure whether it was primary.

Obvious question - why did you not update the index? Was it that it was obvious Google was going to win and made people give up? (edit - never mind - you address this in other comments)
I won't generalize it.

I was the youngest child of an old couple, and I lost my mum about 10 years back, and I am going to lose my father sometime in future, and I have been constantly thinking about it - literally everyday I have time to think - for the last 20 years of my life. I am in my early 30s!

I have been grieving passively most of my life, because I have been acutely aware of the mortality of my parents, and cannot say its healthy. I wish I had "known" less about my parents mortality.

I guess, my point is - death of loved ones suck, and everyone handles grieving differently.
