Nerfs don’t contain a surface representation, but instead contain a occupancy field to represent the shape. This has implications for rendering speed (you generally need more samples along each ray to get an accurate representation). It also has implications for uses outside of rendering, e.g. in physics simulations where you need to know exactly where the surface is. Lastly, you can use SDFs to get arbitrarily detailed meshes by sampling the field at some resolution, who which is trickier with nerfs because the surface is more fuzzy.

Unmodified motorcycles don't actually meet the 80 decibel limit in all situations, they just have to pass when ridden in the specific profile the test defines.

Making this limit 80 decibels in all situations would require major changes from manufacturers.
It's definitely fair to blame the book when the book gives advice that is impossible to follow.

If it's not possible to always give help and advice, sometimes you have to give an error message and unless the book mentions that then it is definitely fair to blame the book.
They do, I even used that professionally at a previous position.

$5-10/mo box with Dokku installed gave us a heroku-ish platform that could be scaled up if needed. The main downside being that you have to manage it yourself, but it really was quite easy for the scale we operated at. Can't speak for larger systems. But if you need a pretty simple, quick-deploy, small-ish-load servicing then it's a breeze.

This reminds me of phase-problem from protein crystallograpy (PX). I'm 15+ years away from that space, so I have no idea what the modern solution space looks like, but it seems like there's a corollary between reverse-AD-over-SDFs (in this work) and the MLE methods for inverse space in PX. It feels like we should be able to take an initial estimate of some SDF over the direct space (2d object) as an ellipsoid, flip to inverse space, do an MLE for phase improvement, and then just do the regular ping-pong on that. The MLE (and successor?) methods are really robust.

Now you're telling me airplane fares also don't include airport construction? I'm beside myself!
So on the point of maths, maybe you should break maths down like people would break a computer program down in order to teach programming?

What I mean by this, is that many maths symbols are like functions or constants, and once you know the rules for a language and its compiler you can code, the same goes for maths, except its a universal language all over the world and the compiler is the rules which is the same all over the world.

Thats why some teachers say if you are good at maths you will be good at programming.

So identify the functions, constants & rules a 5year old will be expected to learn, teach them those, repeat for the next year.

How hard can it it be?

There is a debate over whether people should be expected to learn to do the long hand calculations on paper in this day and age, but thats like teaching kids to bang their heads against a wall when there is no need for it, although I'm sure some hackers will jump in a say there is a need for it just like there is a need for working out binary in a memory register, although the later is a more common example.

Obviously there are a lot of tricks in maths which can also be taught.

This gives you a Heroku-like experience on a single machine and could be enough for your needs.
I think there's a key difference that puts programming a bit further ahead in my opinion - you can make a backup with software. You can 'undo' what you've tried, or reset the whole thing. In general with physical things you can only move forwards, and potentially you can make things way more broken than they already are. That's a useful lesson in itself, but if people are learning it's good that they're not scared of making mistakes. It's a lot harder to make things catastrophically broken with code (despite my best efforts).
They do also appear to work out stuff I’m interested in… there are rare days where I’ll get a stream of promoted Kickstarter projects that actually match my interests… then it goes back to the most generic advertising and I’ll be back to slamming the skip button.

Why you think people expect free? People buy expensive games on consoles and steam, some developers buy expensive IDEs,editors, subscription to services. The only expectation is that crap should be free, like you made a shit TODO app in a weekend why would someone pay for it?

I agree, a simple way to free trial an mobile application would help, also have the greedy giants tax apps exactly the same how themselves pay taxes (only on profit and only after all possible loopholes are used)

...or maybe the risk of "getting hacked" is not as big as it is made out to be given some simple precautions? I am not the only one who "got lucky" after all. Given an up to date distribution with only needed ports open to the 'net and a sensible password for those who use SSH password authentication you'll be safer than at most cloud providers. It is, after all, far more lucrative to try to gain access to the likes of Heroku than it is to JoeSchmoe.org.

Also, "needlessly condescending", give me a break. This site is called Hacker News so it is silly to call a call for exploration - the essence of the hacker spirit - "condescending".

Recently, I've been with people who unlike me don't have youtube premium and I loathe the ads. I'm so happy I pay for premium so I don't have to experience this.

I want to say "subscription is the right answer" but it clearly isn't enough for some people (netflix).
My dad got an internet connection when I was 15; 1999 or something. One summer I got bored, got on my ISP's "portal" website, there was a chatroom feature (powered by IRC), I entered a channel about Buffy the Vampire Slayer. I didn't care for the show, but the ratio of guys/girls was great. All were teenagers like me, made some friends and chatted with my first girlfriend which I met some time later.

It was an easier time back then.

While it’s frustrating to deal with situations like this, in my experience Apple doesn’t have a problem compensating customers for the trouble. I’ve gotten free iPhones, an upgrade from a 15” to a 17” laptop, and free headphones among other things. You just need to ask, as it’s rare for Apple to offer.

Do these variations only appear on the website version of YouTube? I use an ad-blocker so I haven't noticed this pattern exactly. However, one pattern I've noticed using the mobile app is that in order to disrupt the automatic habit to skip, they seem to randomise whether or not they make any specific ad skippable. It seems some ads are always skippable, some are sometimes skippable and sometimes not and some are never skippable. It doesn't always correlate to how long the ad is either. Overall this seems to result in my actually watching the ad all the way through because it takes too much effort to figure out what kind of ad it is and whether I can press the button at the right time. At least if I do nothing, I know the video I want will play eventually.

I've found the highest success rate by adding on to what they're already interested in when I see an opportunity.

To have a valid train ticket on your phone (for those without printer), you are also required to accept the google or apple terms of service and privacy policy. You can download a pdf ticket, but the data matrix on there is only valid if you print it out!

Last year a big hosting company in the Netherlands introduced a requirement for existing customers to accept the Google TOS/PP before being allowed to log in. Support of course did not see the issue, like literally could not find it. I had to send them screenshots with markings before they saw that the google captcha they had introduced includes some small gray links.

This might not even be such a big deal if the privacy policy explained the data sharing that will actually happen. Rather, there is one fairly short document that applies to literally everything from hosted email to captchas to hardware in your home. Thus it has to say that they will use all gathered data for basically any purpose. Something tells me this cannot possibly be legal (iirc GDPR requires specific and understandable language), but that's the state of affairs.

(Another interesting example was me asking in a chat with ~100 people whether anyone had read the TOS update yet from our broker—the place where you keep your pension money and stuff. The only reaction I got was "anyone reads that? xD".)

Kinda bothers me that everyone is just going along with any terms for convenience. It's ripe for abuse and doesn't have to be this way.
Yeah, that's my experience as well. They've always run ETL type jobs.
I saw this on producthunt i believe half a year ago and over the last few days tried to find it, great timing :D
At work, we spend a LOT of money with heroku every month. We really wanted to use Protobuffers (please let's not discuss that ;) ), which require HTTP 2 for the streaming stuff. So we talked with them and were like "heyy, we need this" and while they didn't explicitly say they weren't going to support it, the response basically boiled down to "yeah, i wouldn't be holding your breath" ;)

1) To gain an appreciation or the gist of programming. I mean, most careers these days involve technology, software. Many non developers have to use "low code" software.
2) They might discover they DO like it and pursue a career in it. I think this is no different than other skills or disciplines. Give something an honest try first.
If security guidelines say that you'd be more secure without an ad blocker than with one, then you should probably find a new set of guidelines to follow.
I don't have empathy for loud pipes on trucks, but for motorcycles I give 'em the benefit of the doubt. Speaking as somebody that rides a quiet motorcycle and has almost been hit by inattentive drivers. The people that complain about the noise are implicitly valuing their own comfort over another person's safety. Even if you say that riding a motorcycle is an unnecessary risk, the tradeoffs are still obvious to me.

When it comes to life and death on a motorcycle, the precautionary principle applies- anything that makes you more conspicuous is generally safer. I'd trust my own intuition over the unreliable state of scientific research on the matter.
I do not find it condescending. I find the perspective refreshing. Of course self hosting is not an option when building a product, you want to outsource what you do not expect to become an expert at and which is not part of your core business. Any form of operations and hosting quickly becomes such a thing.

Having said that I have also self hosted to 15 years. Arguably services that gave high utility, but never anything related to core business. I for one host everything on Digital Ocean. As a consultant I dont do enterprise cloud deployments very often, but when I do, I chose AWS and the client has the funding and pays for it.

Wait, you’re talking about Hollywood/ PostWW2 Western media, right?

I agree that it's not valid to claim that websockets are the best fit in every situation. If the requirement is simply to stream server to client events, in an application where that doesn't depend at all on having any per-client state, then you can serve those things statelessly with SSE or HTTP/2. However, much of the time, the thing that makes websocket implementations complex isn't anything to do with websockets per se, but the fact that the server has per-client state; this state needs to exist somewhere in the backend, and it needs to survive reconnections (and so can't simply be some ephemeral session state in the specific server handling a connection). In this case, you could be using HTTP/2, or comet over HTTP1, or websockets, and the main technical issues you will face scaling to millions of users are going to be essentially the same. Websockets (at least, until web transport is here) just give you a more convenient and efficient primitive.

Sure, my point is that a post on pratt parsing is not a substitute for a post on recursive descent, which is what it seemed like GP was implying.
Instead of trying to argue for the point, take it from a point of view of trying to be a teacher and everyone reading your post is a student.

Only ideologues are going to demand phd thesis levels of sourcing for an anonymous forum; but if you source well enough... this ratio becomes unimportant.
> Rechargeable AAAs are crap though. Power density sucks. Voltage level sucks (and voltage regulators will suck the battery dry before your micro does). And the form factor sucks.

Not in my experience: our main TV is connected to a 2008 computer running Linux Mint that we use for netflix and amz prime. I've been using it in this way since 2016. The remote is an off-the-shelf wireless pointer thingy with a few buttons on it (works like a Wii controller) that takes 2x AAA batteries.

I've been recharging those 2x AAA batteries since 1996, and it still works fine enough that I don't feel compelled to replace them.
Uber CEO: company will cut down on costs, treat hiring as a ‘privilege’
Yes, reputable digital calipers are fine for thousandths of an inch. A micrometer is good for further precision and when you what more consistent measurements of softer materials. For example, if I measure my set of - gage pins, the caliper agrees exactly with the spec (a .210 pin reads 0.2095), and it's pretty hard to torque down too tightly on hardened steel. But if they were nylon and not steel, you'd probably get better repeatability with a micrometer. (And it's worth noting that the pins generally aren't actually half a thou smaller, a micrometer reads 0.20990. If 4 ten-thousandths of an inch are important to your project, yeah, you need a micrometer.)
I'd be a lot more willing to pay for Premium if it were strictly to get rid of ads, without any of the bundled features that don't matter to me (e.g., Music, background playback, etc.).
