> Should someone get a ticket for going 66 mph in a 65 zone?

Speed limit laws should not even exist in the first place. They are a paradigmatic example of laws that are unreasonable and should not exist. The fact that it is impossible to enforce them as written, or even with light-years of as written, is one reason for that.

> I don't really think officer discretion is avoidable to a certain degree.

To a certain degree, yes. But it should be limited. In the system we have now, it's not; the scope of laws on the books is huge, to the point that all of us are probably technically violating multiple laws every day, and we are all relying on a huge amount of discretion on the part of law enforcement to allow us to go about our business without continually being interrupted. That's not good.

> there are always going to be Karens that call the cops for no reason and the system has to be able to deal with that.

Yes, and the way to deal with it is to have the law be reasonable. It is not to have lots of unreasonable laws on the books and then hope that law enforcement exercises discretion in practically all cases, only actually prosecuting the "really serious" ones. It's to not have unreasonable laws on the books at all, so when a Karen calls the cops for no reason, the cops can just say "Ma'am, that's not against the law, nothing for us to do."
Glad to see "chemical imbalance" make the list. It is very common to see people use terms like "dopamine hit", "endorphin rush", "low serotonin", etc. in ways that don't make scientific sense.

I assume people do it to sound knowledgeable or to make it sound like their ideas are backed by science, but neurotransmitters are vastly more complicated and subtle in their effects than is implied by these kinds of usages, and emotions and behaviors are tremendously more complex than the "my neurotransmitters made me do it/feel it" narrative would suggest.
There's far more than 2.

Even just taking RV32I, you have M, A, F, D standard extensions which are all optional. A CPU could include any combination of these, so you have 3! possible instruction sets off the start line. But let's assume we're working with G (which means all of IMAFD)

Many PC grade processors will support some or all of extensions B (bitmanip), T (transactional memory), P (packed SIMD), V (Vectors), C (compressed instructions), RV64I, RV128I, Q (quad floats), and not to mention all the non-standard extensions.

See: https://groups.google.com/a/groups.riscv.org/g/isa-dev/searc... for non-standard extensions.

You also have vendor specific extensions such as those from Huawei: https://github.com/riscv/riscv-code-size-reduction/tree/main...

As an application developer, finding the right set of features for your users will mean having to distribute many different binaries unless you stick to plain old RV32G, which has the capabilities of a ~20 year old x86 processor.

If you assume all standard extensions, it only takes a processor to lack 1 of them for the program to not work.

You can test for feature sets before running any of these instructions, but this is more commonly done at compile time via the preprocessor. This is what I mean about developers changing their perspective. It will be necessary to move all of those #ifdef __FEATURE__ to runtime, unless you recompile on each processor.
What does leverage mean here?
You are actually right, but it is not contradictive in any way to what I wrote.

'Westernization' of Ukraine is a problem for Putin, since Russians could realize that Russia can have a much better government that would make life of normal people better (now hundreds of them die in Ukraine every day, while oligarchs rob the nation).

Putin got into power since 'westernization' of Russia failed (also helped that KGB blew up some apartments). Different thing is that this 'westernization' was poorly done if not sabotaged from the start. Also the clique that rules Russia (including Boris Yeltzin) was never interested in 'westernizing" Russia. They just wanted to be rich and powerful.
Gorbachev was the one that tried to move the country forward, one thing is if the country was even ready for that, other thing is that in many ways he failed.

Also Ukraine is not Russia. Ukrainians are the ones who can decide what will their country do - and they decided to move closer to the West.
Wow. Really crazy. I know it was not right to revoke the key, he touched into their system. He probably broke someone’s production.

But it was also absolutely the right thing to do. A god mode key floating around for over a year unrevoked, with real human beings’s medical data on the other side… I am glad the post author revoked the key. It is probably too little too late but they did close that door and maybe saved someone some pain: not the negligent development team, but a real patient and human being, perhaps many of them.
For context, I work for Amazon, have multiple Alexa devices, an Oculus Quest 2 and I think the Metaverse is absolute bullshit and will never bring a cent.

But I totally disagree with the comparison between Alexa and the Metaverse. Alexa has adoption and struggles with monetization, while the Metaverse struggles with adoption but would have endless possibilities for monetization.

What is condemning a lot of Alexa teams today is the complete inability for Alexa to be anything more than a music speaker that also tells you the weather and sets timers. It's tedious to interact with and it's impossible to monetize, just because of how limited the "interface" is.

The Metaverse will never struggle with the same problems. It's not gonna work, but not because it can't be monetized.

This isn't going to disrupt any kind of airline traffic. Battery energy density needs to improve by at least an order of magnitude - probably two - before it has any significant aerospace application outside of drones.
Very realistic, I one had a different idea of how we would build a retool-like tool for a company I worked at. I spent 4 days to reimplement our app from scratch, I didn't include even 10% of what we had, but the framework was much more powerful.

I typically code for like 3-4 hours a day, maybe 6-7 when I'm super into what I'm doing. BUT, I very frequently think about my work when I'm not working.
Absolutely. I'm singling out suburbia (specifically, suburban car-dependent monoculture) here as the least ideal of the three "spheres."
Anyone want to break this down for us? I thought we had no idea how the brain worked especially at the synapse level.
Just want to point out that adults can be just as cruel or even crueler than children with just as little empathy. I don't believe or buy the idea that it just a kid thing.

Like most apple software, it only considers users who are totally bought into the ecosystem. I hardly know what you mean, "grab a copy of my notes", all my notes are copied to all my devices, as long as those devices run Apple Notes ;)
If you adapted it for software, it's almost the same as saying "don't focus too much on the happy path, make sure you limit the blast radius for the failures cases", which just sounds like sensible advice.

You really have to take the adversarial mindset when thinking about large scale systems like this, to make sense of how they can break.
In most areas it is probably safe enough... but they like to keep the population scared as they are easier to control that way... and the police budgets keep increasing.

On average, the cops are nuts in the US... It just take one hot head in a group to make them all act badly...
For the sake of the Hacker News audience I wish "introvert" was its own category and not under "Personality Type". It is baseless pseudo-science but comes up in tech-related circles all too often.
Hahaha, this is delightful :)
By all measures being what?

I think if we’re using a definition of “middle class” based around at least half the population always falling into it, a proper summary here would be that the lifestyle of the middle class continues to deteriorate as traditional assets like homes become increasingly unobtainable.

The average car lasts about 12 years. Sure some collectors cars will be kept running for decades, but it will take about less than 2 decades to replace essentially all cars if we only made EVs. Only selling EVs is the law set to take effect in a few years.

I'm sure that the law will be rolled back a little when one of the 5-10% usecases where EVs don't work screams loud enough (probably shipping and remote areas), but it will become hard to find fuel for your gas car in a couple decades.
Show HN: A crypto social trading platform that force people to practice stoploss
Hi HN,

I was watching an interview of Caroline Ellison (CEO of Alameda Research) the other day and found it interesting that she never uses stoploss (no wonder shit happened). One of the most important skills for traders is know how to set up stoploss and stick to it when stoploss is about to hit. I see that most crypto traders don't follow this principle.

On the other hand, there is a segment in fintech called prop-trade challenge. This is a proven business model in forex & stock trading with multiple platforms having 100k+ active users (such as Topstep or FTMO). These platforms evaluate day traders’ performance in real-time simulated accounts, in which those who pass the evaluation/challenge earn a funded trading account (while still being monitored against its max drawdown rule).

I realized that prop-trade challenge can be integrated with copy-trade functions and create a better version of crypto social trading platform than the current Etoro model. That's why I built Tordess (a “misspelling” of tortoise).

We launched our MVP (open-beta) on October 15th, acquired 700+ beta users/testers as of today and secured affiliate partnership with 2 major Vietnamese crypto trading & prop-trade (Facebook) groups that have more than 200 thousand members.

Since launch, several top traders on our platform have produced 100%+ return on simulated accounts, without breaking our rule of maximum 10% drawdown. While it is amazing how talented retail traders are able to achieve such results in crypto bear market, it also shows the potential of fixing social trading (copy-trade) model by combining prop-trade challenges.

If you find this interesting, please give Tordess a try. Our competition mode is always for free.

Go look at comments at some place like Ars Technica. They are covering/click-baiting all this stuff like crazy. I don't know how clued in commenters are there or if they are actually tech workers but the groupthink there is very strong.

Eh depends on what you call equivalent. A base model 2023 Toyota Corolla is $21k, a fully decked out one is $28k or so. A 2022 Nissan Leaf is $27k. So not quite double.
It really depends on the exact framing of the question.

Like Linus Torvalds. Lispers tend to make similar claims. So does Alan Kay about Smalltalk. Yet most of the world runs on top of C/C++, or COBOL (or Java) for financial transactions and Fortran for heavy duty numerical calculations. Not that FP, Lisp and ST don’t have their advantages. They clearly do. But their supremacy is overstated when it comes to code that runs the world.

No, it doesn't, it's still a matter of luck.

I've certainly experienced this; and I've experienced cases where I'm lucky and we can sit together. But it's very typical for parties to leave single seats between and for you to be stuck with scattered single seats.

It's erroneous to equate "empirical" with "experimental" or "quantitative". Those terms don't have a relationship like 4 = 4.0. Your example in your second sentence is an example of equating empirical with quantitative.

Empirical makes more sense when you contrast empiricism with rationalism. It's a split between things you observe and things you think. If you're doing chemistry calculations, that's not empirical but it is quantitative. If you're pouring stuff into beakers and writing down what you see, it is empirical and quantitative.
At the same time we have a need to make sense of things. And having a rough relatable framework can be part of the therapy. I can also see why it might be dangerous “e.g. dopamine hit good, what foods/drugs will give me that”
There have been an unending stream of Musk worshippers, or general billionaire-worshippers such as yourself, but there have been many people highlighting Musk's many, many, many, many failings for several years.

It’s interesting to think about how much of a perspective shift this must have been, especially the service oriented bits. Interestingly, I think it might not have even been made completely in the authors’ minds at the time of this proposal. (Which is understandable, of course. It’s a proposal, not a retrospective on already accepted ideas.)

For example,

> In the case of DC processing, customer service and other functions need to be able to determine where a customer order or shipment is in the pipeline. The mechanism that we propose using is one where certain nodes along the workflow insert a row into some centralized database instance to indicate the current state of the workflow element being processed.

definitely doesn’t seem to reflect the hiding of a database behind an interface. (From a workflow node’s perspective, rows in that centralized database should be an implementation detail it has no knowledge of.)

Then again, this is part of their pitch for workflow processing, not service-oriented architecture.

I have autism and only discovered it two years ago at age 33. I have been intensely researching it.

The book Neurotribes presents a very in-depth picture of the history of autism and the research and theories for the past century.

This is not saying that autism is not real, that it is not a thing to understand, or something that should not be researched. It is only saying that the idea that autism is On The Rise in a terrifying way, that it is something to be feared, is misguided.

As this article says, and as the book Neurotribes explores in depth, autism used to have much more strict criteria for diagnosis. Connor, the leading researcher of autism for much of the 20th century, was convinced autism should only cover the most severe cases, and he did not like the spectrum idea. As time went on and it was realized that many more persons may have some aspect of autism even if it isn't extremely severe led to the DSM making the criteria much looser. The authors of the DSM particularly noted that this may make it seem like the prevalence was increasing when in fact it was simply more widely diagnosed.

The reason for caution of using the term "autism epidemic" is that it spooked many parents into thinking there was a horrible plague afoot, and that it needed to be cured.

My current understanding of it in myself and wider society is that it has always been around, that those on the spectrum hold an important place in society, and that rather than finding a cure (if this is an epidemic) is more important than understanding autism and advocating for services to help those who have autistic children.

This absolutely does not seek to discredit the indeed heroic efforts many parents have gone to to support their children, in fact by being more precise about what is happening the hope is that autistics like myself can have even better outcomes.
Nearly every system I worked on that had significant business logic in SQL turned out to be a maintenance nightmare. Used to be a lot of this in the 90s or early 2000s. Where dB venders encouraged it for obvious reasons.

It's not particularly early in technology terms. It's very early in terms of society, finance and money, though.

It took us at least 3000 years to go from coins to fiat currency, and we still don't really know how it works. It took 50 years to go from physical money to mostly digital, and we're still not completely there. Contactless payments predated Bitcoin and they're still rolling out in the USA, despite being a very minor upgrade on the existing technology. Up until fairly recently, finance industries wouldn't even touch the cloud. I mean the USA only reached 50% internet penetration in 2000, and packet switching was invented all the way back in 1965, and was still considered a new technology by many in the mid 2000s.

Cryptocurrencies might completely fizzle out, or they might completely replace the modern finance industry. Personally, I think they'll die in their current form, but we'll take some of what we learnt to build new technologies. My view is that CBDCs have more potential than cryptocurrencies, but there's still a lot of cross-pollination going on between the two right now.

For what it's worth, I don't own any cryptocurrencies and haven't for years. Never touched NFTs and I'm still not really entirely sure what Web 3 is. I stopped paying much attention when the whole industry was overrun by bros and shysters. I just don't think it's wise to completely dismiss this branch of technology so readily. Certainly not in a global bear market when everyone is doubting everything and dumping their risky investments.

We want to ensure fairness. We know this situation was confusing, and it was unclear to players how many Pheons they should claim and how it was exploited by others. Although we initially stated we would not take back any of the Pheons that were distributed, we feel that fairness means everyone receiving an equal amount of Pheons.

To accomplish this, we will be removing the Pheons that players initially received from the mail and instead granting 30 total Pheons to all players. Please note that with this adjustment, players who previously collected and spent more than 30 Pheons from this incident will keep their purchased items but may see a negative Pheon balance.
