Disclosure: Work on mobile infrastructure at Spotify.

A lot of the Spotify app isn't perhaps visible at a first glance. Besides the key features I'm sure you're already familiar with, there is also an extensive number of 3rd party integrations (cars, wearables, voice, social sharing etc).

The app as a whole is 1-2M LOC Objective-C & Swift.

> I mean, phones were very very different when the law went into place.

I don't know exactly when the previous law came into effect, but I remember the Nokia 3310 (released 2000) had games on it already.

> If you ban it completely you'd also ban using GPS/Maps/Sat Nav apps.

Yeah, hence I wrote about excepting navigational purposes in my comment.
Hah. Yes.

The redaction/retraction confusion here is rather funny.

"Redacted" scientific research on covid, would make a conspiracy theorist out of me too :)
To be fair, it's not necessarily the case that an unvaccinated population is the best case for masks. If vaccination reduces infectiousness, adding a mask on top could push a small exposure down to a noninfection, whereas a one-time large exposure would overwhelm it.
You did the right thing. If it were a client, I would have said hey, I wrote this amazing way to automate your job and I'm going to save you half the time I estimated.

Half being contingent on how much originality went into the automation process. If you just did away with 300 hours of work for yourself in one hour, charge 150 hours.

[edit] How many hours they were expecting is also key here.

[edit2] but you morally did the right thing, and your colleague who took the summer off is a jerk. Hopefully you spent the time doing something more useful than repetitive work, and that is a reward in itself.
Check out Richie. It is a modern MIT-licensed LMS built with Django and React.

It is used by FUN (France Université Numérique) a public MOOC platform, and EduLib, which looks like the equivalent in Canada.

> For a smaller dev, does saving some percentages of profits to distribution make sense?

No, because NFTs don't cover distribution because even a 2d indie game can be multiple gb so won't be on the blockchain.

It also ignores that a big feature these distribution platforms offer to developers is discovery too, whether by recommendations, charts, or just seeing what your friends are playing
> We can see easily that no human has an IQ of 10x the average.

IQ is by definition normally distributed. If you define wealth the same way as you define IQ (basically as position in normal distribution), not even Jeff Bezos will have 10x "wealth IQ". He is richer than ~99.9999999857% of people, but he will score in such test test around ~6.3 standard deviations, as you can verify through https://keisan.casio.com/exec/system/1180573188 That would correspond to score 250 IQ (Cattel scale).

And about cognitive abilities in general - yeah, some people exhibit 10x times bigger working memory (roughly corresponding to RAM) than average.
Well, i'm in the EU and wire transfer fees are capped at 2 EUR no matter the amount. And they're close to instant.

I don't see the improvement here.
Why do you think that I am being snarky? I thought it was the very first question anyone would ask?! If you can't even do this basic thing that only devs would use (hence I assume it to be a much easier first target to get working as they are technical and can jump through hoops if necessary), then I imagine there's very few things you can make work, currently?

That said, it's nice to see there's some serious work going into this new stuff... driven by a non-profit foundation https://radicle.foundation/ , that does make me take it more seriously, I will check it out.
I happen to be double-vaccinated; but being a rebel I went to have a cafe breakfast a few weeks ago without the appropriate paperwork. The waiter didn't feel like making a fuss so I got to eat.

Being ejected, fined and/or arrested for not having the correct paperwork to have breakfast is not a situation that has ever come up for me before. This is different from in-school vaccinations.
I don't get what your point is in relationships with what I wrote.
People are usually talking about being against having tax payer subsides for hydrogen powered consumer vehicles being inexplicably higher than those for battery powered vehicles.
Vitalik is one of the best people to follow in the space because he generally ignores a lot of the hype and focuses on way decentralization can change (and improve) the world. While there is a lot of value in defi, by its nature it attracts users and builders to the space for the wrong reasons (and in some ways taints the general perception of what blockchain tech is capable of)

If anyone is interested in the decentralized web without the ponzi-like elements (I say ponzi-like though I should reiterate again that I think defi has value), I'd recommend this talk by Vitalik, "Things that matter outside of defi": https://www.youtube.com/watch?v=oLsb7clrXMQ
The most likely source for the assumption:

Straight staircases running against defensive castle walls have intentional design rule where those going up have right hand against the wall. Right handed defender can hack downward freely. They can also have intentionally uneven step length that makes running the stairs difficult.

Similar rule is not as useful inside the castle or tower but, it might have been still used from time to time.
So you have a choice, while the alternative is very inconvenient.
I've always heard it as masks being more to protect others during the time where you're infectious but largely asymptomatic. At any rate, you can't prove you're uninfected easily - but masks are trivial to validate.
I find it disturbing that everytime someone points out the actual science of masks (ineffective for stopping viral transmission) they are immediately downvoted or shouted down online.
One of the more interesting things I've felt about web3 is the idea of portable identities not being locked to centralized account management systems/walled gardens. This applies to tokens as well - eg, an asset that is no longer locked in to a particular game and could be used anywhere on chain. I'm thinking of MMORPGs having their servers shut down. It's interesting to imagine these things existing beyond the games themselves. I'm not a gamer (nor a collector of anything really), but I could imagine how interesting it would be to hold on to one's relics from these games, bringing them into new virtual worlds, even passing them down like family heirlooms. It seems like something that was often dismissed until the NFT boom lent some credence to the notion that digital artifacts need not be entirely disposable. Be it better or worse for the world, ultimately it really is a bizarre but fascinating experiment/exploration into our ideas of value and provenance.
There's no such thing as a "one way tint".

With all its warts NestJS is still a great choice if you want everything to be well structured with a touch of "enterprise grade" - whatever that means. Compliment it with an Angular front end and you've got a frontend and backend with very similar structure.
> Just ban phone usage nonstop already like other, sane countries.

Can you give a specific example? There are only a few countries with safer roads (e.g. Norway, Sweden, Switzerland depending how you measure) and I know that Norway has less restrictive laws and Sweden has almost none except for egregious behaviour like texting (last time I checked.)
> For many of us a dearly loved date has already been selected, which makes our estimation efforts really interesting as we endeavor to shove more and more "stuff" into that bag.

The problem is not to ask for estimates, companies need to budget, plan hiring, and inform clients. The problem is that many companies do NOT ask for estimates but create delivery dates out of thin air.

So, I agree that estimates are a waste of time if they are not used. But they should be used as are part of any reasonable-managed engineering project.
Isn't that the point? Navigation software has audio cues for turns that let the driver keep his eyes on the road.

If you need to read a map, pull over, stop the vehicle, and read the map.
For the most time we had vaccination quotas beyond 95% with voluntary vaccinations. Truth is, the performance of the current ones is mediocre at best as Covid already mutated. This isn't comparable with vaccines for a lot of other diseases aside maybe for the flu.

What brought us into this mess was idiots in charge and part of the population being exceptionally scared. We will continue this way and the situation won't improve until we are in a state like Sweden or Spain.
I got sucked into React, graphQL and Nodejs and and always missed Rails, with all the hype I never thought that the environment would be so far behind. It's all my fault.

But now that Rails has incorporated Stimulus as a sane approach to the client-side of things, I'm coming back and it will be difficult to take me away again.
Not only C# and Java, but C++ has auto, Typescript has let, Rust has let and I think many other languages have type inference.
I don't understand how Decentraleyes would prevent sites from fingerprinting me. It is an extension by itself.
There are hundreds of studies. And, it’s pretty conclusive that masks have zero efficacy for stopping viral transmission. But, you’ll get shouted down by the mob for pointing this out. Nobody reads the actual studies.
You claimed distributed computing was unrelated to blockchain. Now you're saying the relationship is one thing and not another, but you're admitting a relationship all the same.
On my current project we don't estimate. It might not be suitable for most projects but we just pick up tickets off the kanban board instead of wasting days every month arguing whether a ticket is a '5' or an '8' we just do the work that needs doing the most.

Apart from underfunding, I think fundamentally the problem is that a good LMS needs to be extremely flexible and customisable to support different learning styles of students, and also pedagogic techniques which vary a lot across subjects and disciplines. It's a complex problem to solve IMHO, with the greatest risk being an overly simplified and constraining system that ends up getting in the way of learning.
I just got a new mac and it came with a fingerprint sensor and asked me to fingerprint myself the minute I opened it.

They can always keep shaking down teenagers for money by hyping a new thing, but they have to keep dumbing down teenagers for it to keep working. Ultimately people won't be smart enough to earn enough to buy the shit they sell, but then again, selling objects isn't really the end goal.
I'm surprised at how few spammers have stolen my non-GMail address from my public GitHub commits or my one AUR package. I've gotten one scam email within the last month, and none I can remember for the past few years before that.
With Visual Studio also. Intellisense works wonders.
> Navigation software has audio cues for turns that let the driver keep his eyes on the road

Considering lots of people place their phone/nav device on the windshield and block enough sight to hide a schoolbus in their direct view I don't think this actually matters all that much.
> The story goes that all castle staircases turn clockwise so that primarily right-handed defenders, fighting downwards, would have an advantage over attackers whose weapon would be impeded by the newel post.

Even if the direction was chosen to give downward fighting defenders an advantage, I don't think that would be the specific advantage given.

Consider a person standing on the staircase. Whichever direction they are facing, the wall side is more impeded as far as swinging a sword goes than the newel side. Proof: imagine you are standing on the center of your step facing forward, with identical swords in each hand, holding them in mirrored positions. As you move the swords around in mirrored motion any time the newel side sword hits the newel the wall side sword will be hitting the wall. But there will be many positions where the wall side sword hits the wall but the mirrored newel side sword does not.

The advantage the newel post side has is that the person going up can can lean the top of their body a little ways over the edge, partly shielding behind the newel post from the point of view of someone going down.

If the newel post is on the same side as their sword then when they take advantage of their shielding they make it harder to use their sword (unless they can lean far enough over to attack around the post). If their sword is on the wall side, then they get the newel post shielding for free.

If you were worried about castle defense when designing your staircase, I'd guess that it is this shielding considering that would lead to clockwise.
Masks have been heavily studied re viral transmission and been show to have zero effect. It’s like people are ignoring the giant body of prior scientific research. Masks aren’t a new idea in medicine.
Even if you have great world-class software, you will get bogged down so easily in university politics and the slooooooow moving oil tankers that they are that I would strongly recommend you to spend your time and energy elsewhere.
That article shows a graph of cement cost increases from alternative energy use, and says:

> As you can see, every low-carbon alternative raises costs more than 50 percent above baseline. The only ones that don’t raise it more than 100 percent are CCS (of the heat source only), blue hydrogen, or resistive electric in places with extremely cheap and plentiful carbon-free energy.

> The alternative that climate hawks would most prefer, the carbon-free option that would work best for most applications, is green hydrogen. But that currently raises costs between 400 and 800 percent. Ouch.

Green hydrogen is by far the most expensive option. 3-4 times more expensive than electric heat. That's the direct opposite of "the real reason we need “green” hydrogen now is for making [...] cement".

This new work will hopefully make green hydrogen cheaper. But if you're using electricity to make that hydrogen, i don't think it can ever be cheaper than electric heating.
Ask HN: Bitter-Free Coffee
Good day!

On most days, instant coffee with milk works for me. However, I have recently started intermittent fasting (5:2), and i find the black coffee to be too bitter. While adding a bit of salt helps, I am on the lookout for coffee that is not bitter, even if that meant i have to learn how to roast/grind, so on fasting days i can enjoy caloree-free coffee.

Currently I am living in Spain, and I could budget ~250EUR. Any suggestions on beans/equipment, and also where to buy? any resources/books (in English) to learn more on this topic?

Thanks much in advance!
Yep im doing this right now. It’s not even required to save too much. Just salary sacrifice everything into your pension

You might not care about types but the computer you are running your code on, cares very much.
What about touchscreens in the car itself?

I’m sure they’re not as much distracting, but they still require more attention than they should.
Maybe I'm misunderstanding the intention of your response, but this doesn't answer the question. Regardless of whether an extension injects code into the page or not, or if it's recommended by Mozilla, it will alter my fingerprint, wouldn't it?
That is a more extreme example so by it will make what I say sound more extreme.

>So I can start owning slaves, if I claim it fits my values?

Keep in mind that owning a slave is illegal in many places. Laws are also shaped by culture. So if you moved somewhere were slaves were legal then yes you could.
I don’t know why but it always gets on my nerves when people decide to address a multinational forum with people from every corner of the world and ask for their time and attention, but at the same time decide to save 2 seconds of their own time to avoid typing out “Learning Management System (LMS)”.

We all are from different backgrounds and industries and same acronyms can mean different things.

I worked in finance, for me LMS is Loan Management System.

The Netherlands bans all holding of mobile phones, enabled or not. Pressing something like "alternative route" is allowed (in the same sense as operating the radio) but only when the device is firmly attached to the car like in a mount.
I work on a team where we build around and run Open edX. It's incredibly complicated to run because it's not built as an open source product. It's just that edX open sources their software after the fact, so they're not investing in making it easy for anyone to run, of to contribute features.

On the team I'm a part of, our strategy is to build open source tools around Open edX, using it as a site builder that stitches together all our external services (video hosting, live conferencing, course content, quizzes, web-facing portal, forum, etc.). That is, until we cover enough scope that we can start to replace it with a flexible and lightweight LMS that would basically just do the aggregation.

IMO it's not necessarily a good fit for the LMS category to try and build a gigantic software codebase that handles everything the way every single learning institution wants it. You end up with a glorified site builder with a bunch of specialized features tacked on.

I see that you brazenly conflate the country with the party in an attempt befuddle HN readers, but that does not work. They are not tricked that easily.

No, we are back to where we started, placing blame where it belongs, on the CCP: first for suppressing the information about a new SARS outbreak and claiming it was not human transmissable, then second for a laughably ineffective Wuhan lockdown. It was ineffective, allowing asymptomatic infected people to escape, for two reasons:

• Some people who did not fancy being put under lockdown left the region by car and found holes in the secure perimeter or simply bribed the patrols, those who were successful doing so shared the routes and bragged about it on Wechat.

• The party secretariat ordered the airport to stop domestic flights, but the international flights continued as usual. Tracing revealed the virus was subsequently carried off abroad, initially to Thailand.
/edit since you've edited your comment/
The law around usage of a phone whilst driving was not so clear cut. A minor UK celebrity famously evaded prosecution by claiming he wasn't using a phone 'as a phone' when he was caught.

https://www.ashmanssolicitors.com/blog/have-you-been-caught-...

Re the case of the lorry driver:
There was video footage of him browsing his phone, he killed 4 people. This isn't normally the case which is why many people think it's OK to drive whilst distracted by their phones ('multi-tasking' is the phrase I think they often use?).

If laws around usage of mobile phones whilst driving were tightened up and rigorously enforced from the outset then it is less likely such a tragedy would have happened.

This was my point. As well as a gentle reminder for anyone who thinks there are never going to be serious consequences of doing similar.

I wondered the same as well. My idea was to change this and build one that worked....

A few thoughts:

All LMSes need to be seen as a result from their surroundings. Education is a very bureaucratic sector with lots of money, just not in the places to make a teachers' life easier.

Current applications are in this equilibrium where they are good enough for the field as a whole. Yes, there needs to be innovation and it will happen, just very slowly.

My 2 cts, it can be done by lobbying with politicians, deans and school boards. Getting them on board, creating a pilot program and buzz. That part will take more time than actually developing the software.

Disclaimer, I build such a system for a customer. It was very specific and trimmed down for their use case.
I find commercial LMSs to be full of dark patterns that substitute learning and value with gaming-like interfaces with achievements, medals, bars to be filled, check-boxes to be checked, Netflix-like hard to navigate to give the appearance of endless choice, lack of human curation so you can only find the most popular but not the most valuable and so on.

If your interest is in selling then yes, nobody has done the work for you for free. Why would they? Open source is geared towards sharing, not selling.
And don't forget the option of just calling into pry at the line in question and typing ls and show-doc. Also ripgrep is incredibly useful for navigating new codebases.
The answer is that decentralization is in many ways considered a spectrum. We're a long ways away from being able to interact with web3 with no centralized points. As an example, you're reliant on your ISP, DNS, and the web of trust (involving tiers of certificate authorities) to even connect to a web3-enabled site from your browser. The most popular wallet for interacting with smart contracts in the browser is source-available, but not open source.

Of course, any interactions with the blockchain directly (calling methods of deployed smart contracts, or transferring tokens), are decentralized, but if you want to verify the source code of the contract you're interacting with, the most convenient way again involves relying on a centralized service (etherscan or similar for other blockchains), while the decentralized way would involve downloading the contract source yourself, compiling it, and comparing that with what's on the blockchain.

My history teacher brought this topic up in my class. He had a less violent theory about the reason for clockwise stairs, which is still related to the majority right-handed population.

That people carrying things up these staircases would be using their right hand to carry the item(s), and so would use their left hand to steady themselves on the wall (or the rope/rail/etc affixed to the wall).
Slightly related, examples for exceptionally beautiful spiral staircases that turn anti-clockwise are the original [0] and 1930s [1] Bramante staircases in the Vatican, which feature a double-helix design. The original could be used by carriages.
