Nice article.

But, beware that grouping things also has its costs. It can grow the complexity of the software both vertically and horizontally.

I like your use of the instinct concept, similar to experience/seniority yet very different.
How does this compare with Estonia and their use of public ID numbers? I just know they don't consider their ID numbers secret the way SSNs are in the US, yet they use them for everything. How do they prevent fraud and ID theft?
You're probably noticing that the two numbers are not multiples of one another and time samples are discrete so the only way to convert sample rates between 44.1kHz and 48kHz is by interpolating. Going from 96kHz to 48kHz is easier, you just drop half the samples.

Obviously with low pass filtering for artifacts due to the nyquist frequency. But you are correct that it won't be a one-to-one correspondence between the audio samples like you'd get if it divided evenly.

If you had 24kHz encoded music would it bother you if it got upsampled to 48kHz? What if it was 26kHz? I think the prior would bother me less because I know the samples are synchronous in the two time bases.
Black silicon photodetector breaks 100% efficiency limit
This is a tricky UX issue at the moment, but I'm sure this will be doable in time.

The nice thing about blockchains is that once transactions are finalized, the state is known, independently of whether or not the user was hacked. With zero-knowledge proofs, voters could theoretically verify that their "right to vote token" (as I've explained in another answer above) was used to cast a certain vote, without revealing their identity.

Now, if the software they're using is malicious, or their device is vulnerable, the election is screwed.

It's worth noting that Estonia manages digital elections quite nicely with their digital ID cards, which use an underlying blockchain-type system to ensure system integrity

I can't agree with you more. I never understood why calendar and todo apps are separate apps.

At the time, Google Inbox tasks started to be visible in Google calendar, and it was an excellent idea IMHO.

When I want to manage my day, I need to mix events and tasks.
Events are not related to me, I don't need to complete them. Tasks are.
But for me, both kinds of items need to be planned over the day.

Currently, I'm using a todo app only, even for calendar events. It seems hacky to me, and I truly miss the calendar view, because 2-D visual representation of the time is really more understandable for my brain, than a simple list.

So, for me, the perfect soft would be something like this one (I do like the minimalistic UI), but with embedded calendar.
All of my screenshots are from the second round we went through after trying to remove apple login entirely.

They bully small developers, because big companies like Uber or Grab have the same functionality with zero problems. While when we try to explain that we use phone number for the same reason, Apple insists that we change how our app looks and works.

I can touch typing but I only used 6 fingers and a lot more on 4 fingers. That puts a lotof load on my fingers and I'm in process of trying to type with 10 fingers. Will this help me?

For some background, I train myself to be left handed as in I started to use mouse by left hand, writing on left hand to help my right hand recover. But nows it's my fingers
Best advice I ever had was to install the Habinator app and start executing my plan.
They already have exactly that, minus the unnecessary blockchain bit. It's called Transparency.

The problem is that manufacturers need to opt into it and there is no way as a consumer to tell on a product listing whether or not the product is part of the registry.

As someone who is relatively introverted, and is very frequently asked to do things outside my comfort zone in order to be successful in life, I can’t help but roll my eyes a little when people are asked to stop being so extroverted for once in their life. I have pity for those losing jobs or being unable to put food on the table because of this, and their complaints are perfectly valid, but for those complaining that they miss being able to go to parties and hang out with friends... I can’t help but roll my eyes.
How large should the sample be before it's substantive?

The British polling institute advises a sample of 1000 for a total UK population of around 60,000,000. Trans people make up 1% so roughly 600,000, with that in mind 57 doesn't seem that low?
Oh, you can easy distinguish the scientists from the snake oil salesman. One faction starts a fistfight mid-presentation over a "debated" detail - while the other goes smoothly into the sales pitch.
Angular is rising. 15 facts for 2020
Hey everyone. I've been into Angular for a couple of years now and I'm kind of excited. My team is developing an open source ngx-restangular and recently, my we gathered to think about the perspectives of working with Angular. The article is the result of it. You may enjoy.
For me it’s job opportunities. In the USA, I think there seems to be enough jobs but globally, it is still sparse.

Receipts Management
In Estonia, a user has a digital ID card, which contains a secure chip. Neither they or their computers can ever read the private keys contained in this chip. The card is minted like a passport or driver's license, so it's basically impossible to get a card for someone you aren't.

The voting system works similarly to this "right to vote" token model in the backend, from what I know of it. The only difference is that the ID card is where the sensitive data is statically encoded (not on a theoretically hackable computer).

They did have some cryptography problems a while back though. The government says it was not too big of a deal because they caught the bug, and would never have held an election with the bug still present.

This is so historically ignorant it’s amazing.
Maybe this is a dumb idea, but what if for each election we issued a ballot containing a unique, random, sequential prime number to every registered voter?

Then, when counting the votes for each candidate we display the running product of all the primes counted for that candidate as a "checksum", or "check product". This retains privacy while allowing individual voters to easily verify that their vote was counted by simply dividing their party's checksum by their prime ballot number and confirming that it is a factor of the check product. By displaying a running product of votes, you can also verify that your vote was not counted before you voted. Additionally, this prevents double counting because the "checksum" for N primes must match exactly N votes and no two candidates can share a factor. By issuing sequences of primes to certain regions, you can get some metrics by state.

Then you institute a rule that if some % of primes dispute that theirs was counted correctly, a recount is automatically triggered.
You can't but how can you prove the blockchain hasn't been tampered with?
If adding a SQL interface makes a system easier to access, that says a lot about how convoluted the original interface is...

Many countries have id numbers which are not a secret. In those countries you simply can‘t do anything with the number. Creating a bank account by mail with a ssn? Impossible you have to be at the department and show your passport.
You cant be at a department? The postal service in germany can verify your identity if you are there, or there are some online webcam solutions where you have to show your passport in the webcam, rotate it by instructions etc.

Yes, and therefore the retailer is incentivised not to sell junk in the first place.

The problem with being an "everything store" is that everything also includes an overwhelming majority of crap, looking at you crappy "genuine sony" camera batteries that held about 10 minutes of charge, fulfilled by amazon.

> True, but can you recall any moment in history, where market forces did not actually make producing "open" devices unprofitable?

I'd say that the early era of personal computers proved it. The Apple II and IBM PC were very open platforms-- thoroughly documented, developer friendly and made with very few parts you couldn't buy out of your favourite electronics distributor catalogue.

They were riotous successes in large part because the open platform meant they didn't have to guess or corral the entire market. Remember that most of the killer apps of the era (VisiCalc, WordPerfect, dBase, 1-2-3, etc.) were third party, and it was largely aftermarket firms selling "six-in-one" cards, Sound Blasters, and Hercules graphics cards that patched the gaping holes in the PC's hardware design.

Conversely, look at a machine like the TI-99/4 series: while on paper a decent machine for the time, it was as "closed" as a machine of the era could be: an unusually limited built-in development platform, and many of the desirable upgrades involved buying a very expensive expansion chassis.

It's interesting to consider what the business tradeoffs of today's walled garden model are. Apple could choose to do a "pure hardware" play, or emulate the early 1980s IBM, where they offered some popular software via their own product line as a trusted source. The result would probably be a marginally larger total addressable market, as it would bring some customers and developers to the platform who needed something that could never clear the App Store before. But would the growth in market size compensate for the reduction in the average cut they can command from the market?
Where is time in this setting? Synchronization of wave length does not involve time. The device is made according the abstract, derived notion of time, same as it used the notion of a number. Nature does not posses any numbers, however. Mind of an intelligent observer does.

It is useless to argue on HN. I have literally 5 or 6 accounts banned for attacking a textbook ideas. It is easy to trace them all using HN backend.

Most of current HN crowd assume that I am some flat earth anti 5G lunatic, while I have background in philosophy, and down to earth physics way above that of downvoters.
For anyone currently using a GUI mail client where HTML mail works out of the box, this is not something they will spend time figuring out before concluding that HTML mails just don't work. And this is a complete non-starter for those who like Mutt on the basis of having something that also works in non-graphical environments.
One hypothesis is that disbalance of 'gender-related' hormones during fetal development is a factor that can cause not only gender dysphoria but also autism / Asperger's spectrum related issues.
I strongly disagree. This is a comment from someone who (I presume) is unaware of the advances in Proof-of-Stake blockchains, and other consensus protocols like the Stellar Consensus Protocol. Databases do not have a distributed way to manage consensus - one of the main things that sets a blockchain apart from a distributed database.

This consensus mechanism is what's important when something important (like an election) hinges on the blockchain being an accurate representation of state. This requires a Byzantine-fault-tolerant agreement. See https://medium.com/loom-network/understanding-blockchain-fun....
The problem is having a proper and publicly defined name for the concept could piegon hole you. It might make it harder to escape in this world of hyper-specialism.

Did they also invent a system which protects against voter coercion? If they did not, they might as well stop now since no matter how secure the voting system is its relevance falls down to zero if it is possible for the local gang leader to coerce voters to vote for 'his' candidate - "my man stands behind you to watch you vote for candidate X, if you so much as twitch your little girl gets whipped" (which works but doesn't scale that well) or "you show me proof of you voting for candidate X or we'll burn down your house" (which scales but depends on vote verifiability and as such is rather easily foiled).
Modelling a quantum symmetric key exchange
That's a pain. It's the same problem as a class that constructs a particular object that you want to customize. The solution is also the same: dependency injection.
I had to do that because of the sheer amount of softcore porn (ads for Chinese livestream services such as MeMe and MoreIn) in the YouTube adverts in my region.
It allows for verification not only by the voter but also by third parties, doesn't it? That would make it possibly to sell votes (with proof!) or threaten people with repercussions unless they vote a certain way.
I think it would be good for people with autism to investigate probiotic food supplements. Digestive tummy issues is more common in people with autism. This is likely due to differences in tummy food metabolism in people with autism. There is a link between brain / autism and metabolism in the tummy bacteria system.

I would recommend looking into and reading up on Biogaia l.reuteri dsm 17938 and l.reuteri atc pta 6475. Brand name “Biogaia Gastrus”. There is a sub community which blends these food supplements with Yoghurt. Some people report better functionality of autism eating Biogaia Blue. Do Internet search for these Probiotic strands and Autism. Hope this can help.
What is a unique, random, sequential prime and how do you actually vote?
I never comment on Hacker News posts but I found this blog post to be so insightful that I had to give my two cents. VenderOps really is a different job and as a "senior" dev in my career I can say that it is a job that I would happily take at this point. I work for a small startup and there is no end to the AWS, Docker and K8s shenanigans we are called on to do day in and day out. The problem is no one wants to volunteer to do this kind of work so the CTO (the most experienced engineer on our team) ends up doing most of it himself. There are paid consultants who will gladly come in and Terraform all your shit but we don't hire them. While some of us may not consider that "real engineering" these professionals are essential to the success of your startup. Once they put the pieces in place then your devs can run with a fully automated CI/CD pipeline and deliver the features your customers want. Then as adoption starts to take off you get into observability, Prometheus, Grafana and the five nines. This is the point when the agile rock stars start to burn out or bail and the need to bring in experienced SREs becomes inescapable. This is the VenderOps state and it is the pit of success you want your startup to be in even if you yourself have no interest in partaking in it. There will always be a place for brilliant people who need to work and the hardest problems but let's face it a lot of us are not that. I know I am not. A lot of us are journeymen and women who just want put their kids through college and hopefully retire comfortably.

This is a ridiculous argument, because it could just as well apply to mail-in voting as blockchain-based voting. I also think this fear is far overstated (do we have any stories of this happening in the US?) and the more pernicious forms of voter suppression and misinformation are downplayed.

If blockchain systems allow 90% of the populace to vote unencumbered, with a 5% inaccuracy rate (which is far higher than to be expected), that's still more democratic than only 70% voting.

EDIT: There are also ways to guard against voter coercion, for example by allowing "fake votes" to be cast, which if not cast with a certain memo in the transaction, will not be counted. This memo can be a PIN that the user is given as their "legitimate vote PIN", without which the vote would be invalid. When the user wants to appease their "mob boss", they would simply vote with another pin, and the vote would show as having gone through.

This is a surface-level solution, but the technical architecture that can be built to avoid voter coercion in a digital system is far greater than that with mail-in voting. With mail-in voting, your "mob boss" just forces you to tick a box, and put the sealed ballot in the nearest USPS drop box.
20 years ago we all wanted 128Kbps MP3 Quality at half the bitrate, AAC-LC ( Yes they somehow market it that way ), MP3 Pro, HE-AAC etc. And yet 20+ years later no single Codec can produce MP3 128Kbps quality at 64Kbps.

It was hard to imagine then, but not only do we now have cheap enough storage to store more music that you will ever listen, bandwidth and Internet speed has becomes so cheap we can now afford to stream it.

So in an interesting turn of event, the major usage is now 128Kbps and above. So often I see lots of 1-2Mbps Video Files having 256Kbps AAC within it. ( Normally you would put 128Kbps Audio and save those bitrate for Video ) And bandwidth and Data are only going to be cheaper in the coming 10 years.

In terms of Standard 128Kbps bitrate and above, AAC-LC in on par with Opus. And AAC-LC is officially patent free, as all patent has expired. HE-AAC v1 will be patent free as well in 3 years time.

Unless you are doing anything that focus on sub 64Kbps, you have an Audio Codec that is not just royalty free with patent grant, but free of patents, and it is extremely good.

I hope one day we would have a decent patent free video codec too.

what's a bigger threat. "selling votes" or unverifiable election.

i.e. we generally say election fraud is not a huge problem because its too easy to get caught.

if that's the case, one would think any vote buying scheme would be even easier to get caught.

Though experiments are flawed in a way that a untyped logical statements may be - they mix and match abstract concepts with "concrete" ones so to speak. It is just a type error as multiplying birds by trees.

Everything which follow the famous two lighting and a train thought experiment is simply logially flawed. Full of type errors.

There is no center to the source of the background radiation, as it is was created at a moment the universe was still a fairly homogeneous soup (apparently) with these photons being created (and absorbed) everywhere roughly in equal quantity.

Only after the universe became transparent did these photons become free, and since they were produced roughly homogenously in that soup there are everywhere in the same quanitity: a background radiation.

Since they were not produced in a localized event, they won't have a center. But since they're everywhere, they are a sort of absolute reference for how fast you're going (actually that's a new and interesting idea for me too, pretty neat).
You can see this by the number of alternatives, I counted 14 different string implementations in one project I worked on.
> They usually don't quite look like their gender of choice

This is confirmation bias. You notice people who don't look like you think they should look. You then think those people are trans, and when you check a few it turns out they are trans. You've confirmed your bias, and now you think it's true.

What you haven't taken into account is all the people who don't fit this pattern: athletic black women who were born female and identify as female but who are assumed to be transwomen (see all the conspiracy theories around Michelle Obama or the Williams sisters), or the people who do pass well that you're just not aware of.
I've written a decent amount of Elixir for a personal project, and have come to a few conclusions.

For a start, it's very different. That will become self evident if you try to learn either Erlang or Elixir, when coming from a language like Python/C++/etc (and though Elixir looks a lot like Ruby, it's still more like Erlang, tbh). So that can be classed as a negative.

Secondly, fault tolerance in Erlang/Elixir/OTP is not quite as simple as commonly billed. Isolated processes and supervision trees can give you a lot of mileage, but the model is not a silver bullet. I found I still needed to create an error boundary to make an application 'Do the right thing' in very specific error conditions (for example, not killing a running process, when making a single, accidental RPC with the wrong arguments).

Apart from that though, I can't think of much else negative to say about Elixir.

The tools for introspection are amazing. I recently debugged a production issue by opening a console connected to a running system, and calling the functions I suspected to be failing to see what they were returning directly. Not sure if any other language has that facility.

Then there's all the stuff built into Elixir, like the test suite, the build tool, and even an official linter / code formatter.

Erlang interoperability is also a brilliant design decision. Anytime I need to use a library for a task, I look through the Elixir community first. But if I can't find something suitable, there's often Erlang code out there with years of Dev time behind it.

This is just a mere fraction of all I want to say about the language. And most it is very positive.
I think it's history: in the 1960's, machines were strongly card (or at least line) oriented, so pure right to left intracard yields a very small "parser" compatible with traditional mathematical notation, and the unavoidable intercard transitions become top to bottom on a teletype.

(FWIW in my array noodling, the equivalent of dfns are given in the haskell style of "expr where defs" instead of the strictly temporal "let defs in expr", which does result in a consistent right to left for those who wish to read bottom-up.)
Not necessarily a dumb idea, but blockchains provide us an easier way to do something similar.

Every voter would be provided 1 (one) "Right to Vote" token after verifying their identity or receiving it by mail (as is the proposed solution from the USPS). This is arguably just as secure as mail-in voting.

Each voter would also have an "on-chain voter ID", which would just be an anonymous public-private keypair in possession of 1 "Right to Vote" token. This on-chain voter ID would never have to be "mapped" directly to a voter. All that's provisioned by the the election overseers is the right to vote with one account by using this token.

Then, the vote is cast by redeeming this right to vote token, without the voting account ever being linked to a "real identity".

Of course, there are problems here too. Mainly with UX, and then at a low level the hardware used (the general public is very easy to hack if you have nation-state power).
