I am a Product Designer with 10+ years of experience. I began my professional journey working at design studios and gradually migrated towards digital product design. My specialization came about through entrepreneurship, graduate programs and experience in tech companies, from startups to larger enterprises.

Although my recent role was managerial, I am deeply committed to maintaining a hands-on approach, leading by example to inspire creativity and excellence within the team.

I was laid off last week, so I'm starting to explore where I might focus on now. Whether you're looking for a founding partner, aiming to elevate the design maturity in your organization, or anything in between, let's chat.
What signals cause rewiring of the cerebellum?

Is there any way to induce that state exogenously?

Some thoughts include dopamine / pain receptor reinforced learning. Maybe there's a faster way?
Seems more parsimonious to explain aggressive optimisation everywhere as contraction pains. Efficiency and optimization as the obsession of a society aiming to rescue itself from encroaching constraints within a historically successful but fading paradigm- the facade of which may long outlast its public interest utility, propped up for the convenient credibility it lends private, perhaps mercenary, interests
Thanks for giving examples. When I look at them one by one, though:

1. Regarding the TV, I would much prefer having a big screen TV, around which I could interact with a group of people, than having us all wear glasses in the same room to watch a movie.

2. Regarding the multi-monitor use case, I know some people have said they already use VR goggles for that, and maybe the tech will eventually get there but I'd never want to do that for long periods - the strain on my eyes and head would be horrible.

3. Regarding AR for new furniture, there are already cellphone camera apps that do this (Amazon already does this with some furniture products). I think doing this with AR goggles instead of a phone camera would be worse in nearly every way.

4. Similarly, there are already AR guides that do this with your phone camera.

If anything, your points 3 and 4 really highlight to me why I think AR goggles are generally a bad idea. I agree that AR is useful in those small examples, but for those relatively short "let me just see how this would look against this physical thing" use cases, being able to quickly pull out my phone (which I already have) and put it back again when I'm done completely obliterates the need for a second dedicated piece of hardware.

The only places goggles/glasses really make sense is where people will be wearing them for extended periods, and my argument is that in most cases people will not want to wear them for long periods.
I know, that was my point. But there was a time from 50s to 2010? or so that US Navy was so strong compared to the Chinese Navy that invasion was not possible at all, the Chinese wouldn't even be able to reach the shores of Taiwan.
Svelte has been amazing compared to React.
> For the past year, I have been searching for a replacement for my Lenovo Ideapad. Its 8 GB RAM couldn't keep up with the bloated software I run these days.

I have the same laptop (using it right now). You can add another 8GB, even though the specs say you can't. (thanks, lenovo...) The big limitation seems to be CPU, despite having an i7-6500U in this one. Opening Google Maps makes the machine crawl, but most other sites don't have a problem. It's definitely not speedy but it is functional with about 100 tabs open.

The main reason I want to replace it is to use a USB-C docking station, have real graphics support ("hybrid" graphics is crap in Linux), and have more than 5 hours battery life. Otherwise it's kind of amazing how well it's working after 7 years.

Even though it's technically "heavy" for a modern laptop, it actually feels easier to pick up and carry around than lighter laptops. The corners are angled/sloped so that they're very easy to slip a hand around, and the case is sturdy held in one hand even when open (thanks to the case being half-metal, half-plastic). Way easier to move around than my Macbook. A great example of how design makes a big difference to usability.

As long as it's clear to the user that they're making a site-wide UI customization choice and just not choosing the language for this specific example I agree with you, but I don't think it's clear in the typical case.
Apple's headset will have a significantly higher field of view so comparing PPI doesn't mean much
I have long gotten used to the idea that I cannot remotely read all my books in my years remaining. It bothers me only a little. When I feel like reading, I have a curated collection to choose from. A large fraction of it is deep dive material, so went I want more than the shallow tripe on the internet, it's available.
My overall read on this article is that its claims are probably overconfident. Like, it seems interesting, but like she's seeing a few results and making big claims about how the cerebellum plays into overall cognition, and my general sense is that lots of humility is usually warranted here: that simple and decisive statements usually turn out to be riddled with provisos and unexplained behavior.
I lived in Spain and never understood how the DNI/NIE's weren't an easy vector for identity theft. You need to give the number to do the simplest things, and many people wanted to see the card (and possibly make a copy). As far as I know the smart chip on my card wasn't used once in 2.5 years. I suspect the digital certificates you could get from the government likely aren't as well protected by the general (non-technical) populace as they should be. What makes it harder for someone to steal identity via a DNI/NIE in Spain than someone could use a drivers license + SSN in the US?

(For what it's worth, I actually liked the national identity card, and didn't hear too much about identity theft - I'm just curious).
Not sure what you mean. I can tell you it pitches a fit if I tell it to go above ~1800x1800 on my 8GB card. I think automatic1111 has a flag to let it page stuff out to main RAM, but then everything is hideously slow.
Then well-made SPAs seem to be exceptionally rare. Somehow that site lags more than opening a new page on HN. You list all the work the browser is doing and yet somehow the SPA is making it do more. I agree it makes no damn sense and yet that is the experience I have of using them.
Anti-fraud departments have apparently not gotten the memo, and the whole situation has gotten obscene in the last few years.

I regularly travel for work and it's impossible for me to make any purchases on major sites like Walmart, Best Buy, Target, Costco, etc. They all will accept an order, charge my card, and then randomly cancel the order some hours to days later, and refund me.

Similarly when traveling internationally, Schwab bank decided they didn't like one of my debit charges and blocked the card. I called Schwab and they gave me some "publicly sourced" 3 question quiz about myself that I apparently failed and they locked my entire account until I can fly back to the states and come into a branch.

Luckily I have a 2nd bank account and was able to change my payroll. But it's just insane to me that some random debit charge has resulted in my inability to access most of my money or my brokerage positions.

I hear similar issues and horror stories from all my coworkers and friends that travel.
I've used WebRTC in JavaScript, but I can't quite get why I would use this library. Can anyone respond with use cases?
Not necessarily. Imagine a microbe that loves to eat lipids, proteins, and other complex organic matter but has itself an utterly alien biology that presents little or no attack surface for immune systems that have evolved to tackle Earth life. Known antibiotics and even most antiseptics have no effect and we don’t have time to find anything that works before we all die, then all plants, then all large animal life. Our biosphere is reset to the pre-Cambrian but with ruined cities and petrified forests.

I’ve studied a fair amount of biology and don’t see a reason this is impossible. Would it be guaranteed to happen if we brought back an alien microbe? No. In fact the most likely scenario is probably that the alien microbe would not survive well in our biosphere. But it’s definitely a plausible scenario especially if alien life were some ultra tough extremophile that can handle a huge range of temperatures and chemical environments and metabolize all kinds of complex organic molecules. Evolutionary pressures in a radiation filled environment with extreme temperature cycles would select for something simple but very very hardy.

This is why intelligent biological entities will never land here in person or vice versa. If we found a crashed UFO with bodies the prudent action would be to drop a hydrogen bomb on it since if they’re anything like us their bodies are walking microbe zoos. We will never shake hands with ET but could totally swap mp3 collections.
It's why I never really bothered with Mac OS or iOS development. I don't have time to waste searching for answers. What an absolute PITA.

I like learning from 3rd party sources, but there HAS to be an official, maintained 1st party source or there is no point.

> A lot of our motor learning is in fact wiring the cerebellum correctly.

That got me interested: since the wiring is so long (from limbs to cerebellum), what kinds of motor learning?

Do we know, if cerebellum needs more energy than the rest of the brain?

Really interesting!! I wanted to implement this kind of system at Wikimedia but I quit my release engineering job at the beginning of 2022. Still think about this specific problem pretty often though. I never thought to use the score in order to determine how much testing needs to be done! That's actually really genius! If I had thought of that I probably could have pitched it and gotten more people behind the whole risk-scoring idea since overall testing times were getting really long on Wikimedia's codebase and targeted testing could have some real benefits in velocity of changes through the pipeline (with associated knock-on effects on developer productivity and job satisfaction).
This is actually the same reason Friendster failed in the face of Facebook, pun intended. Friendster simply could not keep up technically and had to shut down. Later, Facebook actually had a more solid technical footing and could scale quickly.

To be a bit more general about this, I have found that the returns to combatting fraud are highly nonlinear.

Having a better national ID than SSNs would have effectively no negative impact while being a huge benefit for security and fraud prevention. It would also, if implemented well, be hugely beneficial for privacy. For instance things like Signal could move from requiring phone numbers to a ZKP using a national ID.

That worked - once I managed to catch them in the office.

It took more than one try to catch them during office hours. The problem of course is that their office hours numbered just 12 hours a week, and smack in the middle of the workday! 10:30 - 1:30, M-Th
It’s lower boundable though
This hardwired coping mechanism is why populism is so effective, as well as religions, some governments and much more
When I got into iOS development (about a decade ago now) I was absolute blown away by how good Apple's documentation was. It was accessible to someone unfamiliar with their platform, well written, and covered everything from the high level to low level details. Sadly that seems to have also been the exact moment that they fired everyone working on documentation.
I find it odd that you pour scorn on an article that, in the end, agrees with you:

> Despite having seen many arguments that one can extrapolate clean dominance from doped dominance, I will make the case that when a critical mass of the dramatic personae are doping, it is impossible to say what would have happened in a world where everyone was clean.
To me the point of these is not to explain size but more to address the feeling of "it's bigger than the biggest thing you might have experienced"

An other common reference in Japan is the Tokyo Dome baseball stadium also used for live performances, and it feels exactly the same as telling someone you store 5 Library of Congress worth of data in your NAS.
Hold on there!

Are talking about American American football fields, or Canadian American football fields? Or American arena football fields?
I believe this is a trivial thing with a misleading title.

Of course the optimal amount of fraud for a business is zero. A world with zero fraud would be optimal for them.

And (also of course) given that combating fraud has costs, there is a level at which investing more money and effort into anti-fraud has diminishing returns.

Therefore it is not worth it to go all in into the fight against fraud, but accept that some amount of it happens.

Surely none of this is surprising.
Fyi... submitter put "not zero" instead of original title of "non-zero" which causes the "past" link's search algorithm to not list this previous discussion:

What a marvellous article. One thing I’ve never quite appreciated in neuroscience is how useful physical movement is as a debugging layer. During a task, in observing gaits, tremors, speed, accuracy, etc., you’re able to gain a deeper understanding of how cognition works for non-movement tasks. I guess cognition is, after all, still just movement, but through a conceptual plane instead of a physical one.
It still remains a mystery to me why browsers felt they should "fix" this server misconfiguration.

It's particularly vexing to me as the main reason that people end up with misconfigured servers at all is because after they've configured their new cert (incorrectly) their web browser gives them a tick and they think they've done it right - after all, why wouldn't they?

which might not cause any problems.
So classical conditioning in humans requires special cells in the Cerebellum (Purkinje cells), which can even do single-cell learning. Which artificial neurons can't do, as only weights (artificial synapses) are updated. So how is classical conditioning actually implemented in artificial neural networks? I assume there is some minimum network which makes it work.
Recently have the same experience, I was writing a small SwiftUI app for macOS and wanted to detect the hardware keys and handle it, especially the Delete key. It was hard to find it in Apple’s doc. But I figured it out with some random blog and a lot of print() on my end.
They still have a cheaper (by a bit) SE version. The current one's internals are basically the same as the iPhone 13. Still sells for $429 so above the $300 price point. They picked the designation back up in 2020 with an iPhone 11 based one (released concurrently with the 11) and updated it in 2022 concurrent to the 13's release.
The article calls out the reason why this happens in academia: administrators need to perform the thorough investigations even if things appear obvious in order to protect themselves against a lawsuit. See what’s happening with Francesca Gino for example: she’s suing Harvard and the four scientists who uncovered her fraud for $25 million, and you can bet that she would win (or at least make it very expensive for the defendants) unless the evidence is very strong. Institutions are obviously incentivized to not prosecute misconduct strongly, or at least not until the misconduct is so blatantly obvious it cannot be ignored.

They don't because the birth rate tanked, and besides China is going to claim the new land as originally part of the Seventh Kingdom and invade it after Taiwan.
I agree somewhat, but when I separated from my first and only iPhone, iPhone 4, I did miss the ecosystem but that's also why I didn't want another one. From my Macbooks, iCloud, iPhone, the syncing and backing up and all that was seamless, but too intrusive and difficult to even share a damn image w/ a non-Apple device.

TLDR; the Apple ecosystem handcuffs the user, so people stay.

The charitable view would be that they come from language/platform that does include the base-class's methods/apis.

Your example of dotnet/C# doesn't seem to be the best - DotNet/C# repeats the base documentation - for example the SaveFileDialog class [1] lists all of the methods but indicates when the methods come from the base class.

Flutter also seems to list inherited methods - for example the TextButton [2].

To me, a useful cutoff would be to define "C compiler" as anything that can compile TCC (the tiny c compiler, that can more-or-less compile the old C versions of GCC).

Maybe it's legitimate to say "TCC must be a single-file amalgam first and you have to use an external preprocessor".
Case in point, here's the archived documentation on how to use Open and Save Panels, with example code:

Every WWDC is a good time to get in touch with them where they host Slack chats.
My understanding is that they used media they don’t have the rights to or something like that.
I went through four different use cases in the last two months or so, about 1.5 of them not the state. I'd say the chicken/egg phase is over. But it won't be an everyday tool anytime soon, but the same is true for the physical ID, its not like you need to show it around all too often.
I propose using multiples of 1% of the length of the 100m dash. Maybe we can find a shorthand way to write it.

> always surprises me to read people don't regularly use Notepad.

There have always been so many free/shareware editors better in every way you wanted, even in launching speed.

It always surprised me to hear people regularly using it

> I use it as a clipboard scratchpad. It strips RTF when copying between programs since Windows itself has no built-in way of doing so and you can also use it to clean up whatever you're copying.

I'm pretty sure it's not Notepad that strips RTF, it only exploits the windows clipboard feature: the clipboard can store data in multiple formats, and it's actually the applications that support storing it in RTF that also store it in normal text (this is actually usually handled by a control that the application is using, such as win32's Rich Edit).

In short, you can do the same by pasting the text in anything that doesn't support rtf (the only caveat is that the application might reencode and mangle the text when it reads it - old versions of Notepad could do it, for example).

There are also utilities that let you paste the clipboard's plain text directly.

To see what's really inside the clipboard you can use e.g. https://www.nirsoft.net/utils/inside_clipboard.html , if it still works.
I hadn't heard of either of those projects -- both look really cool. Thanks for the pointers!
How is this supposed to protect against timing correlation attacks? If each time User 1234 signs into a particular site, Bob Smith requests a token, we know with high probability that Bob Smith is User 1234 (or anyway is using his ID to request tokens).

You can solve this by giving the user a generic token that asserts that the bearer is e.g. over 18 and is valid on any site for e.g. 30 days, and then Bob can request arbitrarily many tokens on the first of the month and use them as needed. But now all of this ZK proof stuff is making things unnecessarily complicated, because you could then give every user the same token that expires at the end of 30 days. They're fungible and anonymous. Anonymous means you can't distinguish one from the other means you don't need different users to be different, and then you don't have to worry about vulnerabilities in your ZK system.

Which leads back to the main problem with this whole mess: All it takes is for one person with an adult ID to share the token. Which is the problem with all of these systems -- most of the population has an ID and they can share access to it. There is no way to catch them or stop them if they're actually anonymous. If you could, they wouldn't be, and then the system fails as an invasion of privacy.
out of curiosity, are you "privacy conscious", as in minimize sharing your location, personal information, etc?

I have a pet hypothesis that a lot of the security heuristics they use are based on being able to spy on you everywhere you go, and the trail of digital litter you leave behind "confirms" it's you where you are.

It's difficult to draw conclusions from my own experience because the security landscape changes and I don't know what other people encounter. I do know people who spend their lives online on the phone and they don't complain about having problems blowing their whole paycheck every week; like for instance my assistant who doesn't either have trouble purchasing things for me.
It's very unintuitive. It's come up on threads here several times, with people incredulous about the statement.

It has ramifications for the kinds of discussions we have on HN, because the primary stimuli we get are news anecdotes, and anecdotes about fraud can be galling but still under some sane noise floor that organizations don't bother to stop.
For the use case of presenting JSON in a pretty way, SwiftUI is great - let’s call that the happy path. But Flutter is also great at that, and you’d only need one implementation that way.

The problems begin when you are doing less trivial or obvious things on iOS/Mac, like interacting with Bluetooth, or displaying large amounts of data in a list, or forms that scroll like your designer wants them to, or background processing, or…
