The fact that a lot of Chromebooks are being sold is fairly solid; I would reckon that the questionable claim is that Chromebooks have strong sales traction with retail consumers. I bought myself a Lenovo Duet tablet last fall because I wanted a device that could last multiple days with intermittent streaming use and I missed the feeling of a cramped 10" netbook. I got it on sale for $200 USD and was floored by how nice the experience was on a PC that cheap. But friends and family who saw me with the tablet were shocked that I, an adult who likes computers, owned a Chromebook. I only know one other person IRL with a personal chromebook, and they bought it after being given a school-deployed one in college.
A transaction is definitionally something that has been written to the blockchain, so no it isn't.

In the case of layered solutions, you're no longer using blockchain. If we want to count uncomitted transactions on a second layer as "reversible", that comes with a host of its own issues, and points out another intrinsic flaw of blockchain: incapable of fulfilling its philosophical purpose, and requires secondary solutions that violate the very core philosophy of the data structure in hopes of overcoming just one of its many issues.

> We're at early stages of planning an architecture where we offload pre-rendered JSON views of PostgreSQL onto a key value store optimised for read only high volume.

If possible, put the json in Workers KV, and access it through Cloudflare Workers. You can also optionally cache reads from Workers KV into Cloudflare's zonal caches.

> To be honest, I'd hoped that it could be a bit more 'magic', like S3

You could opt to use the slightly more expensive DynamoDB On-Demand, or the free DynamoDB Auto-Scaling modes, which are relatively no-config. For a very ready-heavy workload, you'd probably want to add DynamoDB Accelerator (an write-through in-memory cache) in front of your tables. Or, use S3 itself (but a S3 bucket doesn't really like when you load it with a tonne of small files) accelerated by CloudFront (which is what AWS Hyperplane, tech underpinning ALB and NLB, does: https://aws.amazon.com/builders-library/reliability-and-cons...)

S3, much like DynamoDB, is a KV store: https://news.ycombinator.com/item?id=11161667 and https://www.allthingsdistributed.com/2009/03/keeping_your_da...
Same. I'm convinced OBEs are a form of dreaming, especially when comparing the techniques used for initiating wake-back-to-bed lucid dreaming (relaxing the body & mind, feeling vibrations, being amazed how "real" it is, etc).
This i a good idea, it could use a standardized word list, like the one from Diceware[1] or EFF's Diceware wordlist [2]. Of course there's also an XKCD for that [3].

Yes.

> Should Riad be found guilty, “it’s going to send shivers up and down everybody’s spine who has one of these vehicles and realizes, ‘Hey, I’m the one that’s responsible,’”

Duh. There's plenty of warnings, you are still responsible and your attention is required at all times to intervene when needed.
Of course, there are going to be plenty of situations where it will be too late for a human to intervene. Those are going to look harder, but purely from a legal standpoint you are not (yet) allowed to hand off responsibility to some algorithm just because it's baked into the car you buy.
X% of people are obese, Y% of people are vaccinated. An extremely outsized portion of hospitalizations are unvaccinated. Are you saying that obese people are more or less likely to be vaccinated? Otherwise, it's irrelevant. Yes, hospitalizations likely skews toward obese people, but what's relevant is whether they are vaccinated or not, and clearly most (hospitalizations) aren't.

Let's take the Australia example in the thread. 92% of population vaccinated, 50% hospitalizations are unvaccinated. Unless there's a claim that obese people are less likely to be vaccinated, you would free up every other hospital bed by everyone getting vaccinated (minus the portion still going in, which here would be a ratio of 0.5 x total_beds out of 0.92 x population of those 8%).

Yes, if less people were obese there would also be less hospitalizations, but that's an entirely separate problem. Maybe if no one was obese you would halve (as an example) the number of hospitalizations again, but that's much harder than getting a needle.
Terrific story. Personal, authentic, and very relatable. Interest in and an aptitude for computers also saved me. (I even had a job in a computer store.)

> I made the cold calculation that as painful as my life was, it was probably better than rolling the dice with the child protection services.

Yup. I too decided at age 11, choosing to live with the less bad parent.

And shortly thereafter, those decisions were made for me, resulting in the state putting me into foster care. Somehow I avoided the worst; while the 1st family was pretty much what you'd expect, I later lucked into a good family.

--

I wonder how many of us there are. I've known so many runaways, beaten kids, sexually abused kids, kids with broken parents. And that's just in my wealthy, prosperous city. I can't imagine how much worse it is every where else.

I also marvel that somehow some of us find a way out, while seemingly most others get sucked into the abyss. So much human potential lost due to poor circumstances and stupid luck. It fills me with deep sadness.

And I wonder what the difference is. How are some able to escape their fate? If we can identify those success factors, maybe we can maximize chances for success. Could even be small measures, like how we now have suicide prevention hotlines, and resources for victims of human trafficking.

--

I had many, many people help me over the years. People who had no reason to help, but did nonetheless. I call them my angels. People like a little league coach (who'd drive me to practice), a youth pastor (who mentored me), the foster family that raised me, etc, etc.

As society becomes harsher, more coarse, more dog-eat-dog, I worry that other lost kids won't have their own angels.

One advantage of enums is that you can iterate over all possible values of an enum, but not a union type.
Your impressions are cordect: DynamoDB is quite low-level and more like a DB kit than ready to use DB, for most applications it's better to use something else.
Similar for me, thought I was dying because of the intensity of physical symptoms. Got a lot of blood tests, turned out it was anxiety related - I was surprised at the intensity of physical symptoms that can happen from it.

While I’d guess some “long Covid” is related to serious cases that caused underlying organ damage, my suspicion is in the more general cases where vague symptoms are described it’s probably anxiety.
Yes, that's a good point and I overstated.

Microsoft needs a _few_ software engineers.

Most of their developers won't be and shouldn't be, though.

Conversely, NASA will have plenty of software systems that have nothing to do with spaceflight, like their website.

They shouldn't be paying software engineers to engineer those systems, but rather software developers to build and maintain them.
Autopilot is a free feature on Teslas, and is a simple lane assist system, akin to cruise control. It is not Full Self Driving.
FSD is an expensive upgrade, and is supposed to do things like stop at lights.

Driver was on autopilot, which explicitly warns you upon activation that it doesn't stop.

Clickbait from a once great, now awful newspaper.
The arguments against the four language features in this article all boil down to it not being Javascript. If I wanted to write in Javascript, I'd use files with a .js extension. If you've picked Typescript, I don't think you should worry about whether your code is also valid Javascript "if you remove all the type information" (who's going to do that anyway.)

Unless you're a solo developer, what's more important it to agree on languages and conventions that apply to your team's projects. Once that's done, any change to the team's work process should be a conscious, measured decision.

Note that I also used CoffeeScript 10ish years ago and still consider it to be a superior experience to working in plain-old Javascript.
I don’t practice mindfulness, and I’m certainly not a neuroscientist. That said, from the study linked in the article you referenced to I don’t get the conclusion that the exact opposite has been proven true. I can see roughly 1/4 of participants reported bad experiences that they attributed to mindfulness, but I found nothing about the other 3/4. Did the feel no difference? An improvement? Without that, I don’t reach the same conclusion as you.

Given I’m just a layperson, can you help me understand what I am missing here?
Neither. Change the law to make platforms like Facebook accountable for the content published on them. Here's how you do that without damaging speech or making platform companies impossible: make platform protections dependent on revenue stream. If you are paid by the author to publish their work, you are a protected platform and it isn't your content. If you make money by selling advertising alongside the content or by selling a subscription to the content stream, you are exposed to libel lawsuits, incitement, hate speech, false advertising, etc. The rest will sort itself out.

Previously journalism cleaned itself up because it could be held accountable for outright lies. There is incentive to make outrageous claims because outrage sells. The balance is to create civil and criminal repercussions for provable lies. Lies spread on social media like wildfire because outrage sells and more eyeballs means more money for the platform, so the platform and the authors are incentivized to create and spread misinformation. There is no balance against it, so it will continue to grow.
Who is this clownery even for? Does anyone care about „fact checking“ at all? Personally I have maximum distrust towards those fact checking offers, there always seems to be an agenda behind it.
The US labor force participation rate does not swing by 10's of percentage points. During the pandemic it fell from a little over 63% to a little over 60%. Over the long term, it was above 58% in the 1950's and topped out around 67% in the early 2000's.

Median net worth in the US is $120,000, which includes home equity. You can't retire early on that.
The reasoning behind most of this, that the output JS is not a strict subset of the input is silly and imho represent a misunderstanding of what Typescript is going for. It’s a full fledged language that compiles to readable JS, not just annotated JavaScript.

There are many features in Typescript where it simply isn’t just outputting a subset of the input, and many of them are the best parts of Typescript.

If you just want JavaScript with types, there are other languages that do that, but Typescript offers so much more.
The premise of this article is that a trial involving a crash with a level 2 system[1] is fundamentally different than one involving a level 1, without making the case for that.

In both cases the driver is responsible, and expected to monitor the road. Why would someone crashing while using e.g. a lane-keeping system be in a different position legally than someone using cruise control? Level 1 driving assistance has been in use for decades, and there's surely legal precedence to draw from.

That depends on what your definition of "anti-communist" is.

Given that there are a lot of people who see stuff like universal healthcare insurance, usable public transport or a livable minimum wage as socialist/communist, "anti-communism" can be outright reactionary/ultra-conservative in reality.

It's fine to be against authoritarian communism (China/NK-style governments) / existing "realsozialismus" governments (e.g. Cuba, Venezuela). But labelling actually positive policies like the ones I mentioned as "socialist"/"communist" and opposing these on the banner of "anti-communism" is pretty bad.
Yes. Tesla cars are not self-driving cars, despite their marketing. They probably won't be for years to come. I don't think anyone who has read up on the current state of self driving would come to any other conclusion.

At best the convicted drivers could sue Tesla for damages because of their advertising after conviction, because Tesla puts a lot of effort into their marketing materials to convince people that the car drives for you, but on the paperwork you sign you're reminded that it doesn't, and the software features that force you to keep your hands on the wheel at all times are a constant reminder of that.
I honestly wonder if this is a reading speed thing. I don't notice keeping my eyes on them at all.
And I think (hope) they will ship it.
> American misconception of democracy is that the majority decides the way

I don't understand, a large part of the last 20-30 years of American elections have been an entire outrage over how a such a small amount of people can have such outsized results in elections because of how the system is structured. Its literally the opposite of your take.
> People need to adapt to not believing every stupid thing they read on the internet and actually thinking critically about things.

Sure, free speech is optimal if this happens. But what if it doesn't happen? People are extremely irrational [0], and that certainly won't change anytime soon. What changed is that we got better at exploiting that irrationality at scale.

There's no practical value in stating "in an ideal world, free speech is the solution". We don't live in that world, and we don't get any closer to it by complaining on HN about people not doing enough critical thinking.

I am happy the Internet is here. I feel that it was inevitable, and I also believe that we are just starting to emerge from the "rough teenage years" of teh Internets Tubes.

Maturity can be a real bitch. We'll be seeing a lot more guardrails and walled gardens. People that have become accustomed to (and thrived in) the "Wild West" nature of early Internet, will throw tantrums, but it will be for naught.

I definitely couldn't do my work, without the Internet, a persistent, high-speed connection, and a whole lot of folks that contribute to various sites out there. I often have to google even the most basic stuff. Because of the Internet, these sidebars seldom take more than about five minutes. I do it several times a day.

I have a Facebook account that I barely use. The place is a cesspool. I just keep it, because I need to help support a technical initiative that has a fairly prominent Facebook presence.

What struck me most about her story, is how little help her mother got. Sadly, I am familiar with exactly that type of mental disease, and know how destructive it can be, and how treatable it is, nowadays.
>Short answer is “yes” same way a homeowner can be responsible if they negligently leave some issues on their property and a person falls to their death.

There's a lot of gray area in those kinds of cases. The idea that one is negligent because one could have done something differently tends to permeate internet circle jerks about legal responsibility but these sorts of things tend to be very specific to the facts in question and the burdens of proof differ greatly between civil lawsuits and criminal prosecutions.

In this case the driver will probably be probably be financially responsible for the outcome but being found guilty of manslaughter is a much higher bar. However, many states have various vehicular <type of crime> statutes with lower requirements or "but if driving a vehicle then X" type qualifiers on the definitions of normal crimes so that may complicate things.
F5 and a tally!
Entire fact-checking thing is just the media under disguise, so click-baity articles are to be expected. They often try to present their claims as if the subject they write about is entirely false, even when it isn't. Moreover, it's not only that they are not qualified to write on most topics they write about: all fact-checking studios act under guidelines of IFCN, the "International Fact-Checking Network", so it doesn't matter whether cases like these happen on Facebook or Twitter, they are governed by the same entity that is likely to pursue its own political interests and bias.
Thanks for this! I have doubts about our old building's power being able to support PoE properly but I might give them a shot and see how it goes.
Linux had page cache for a while. Not sure what this should show.

Independently can we pls stop using floppy disks to show how slow, fast, small or big something else is in comparison?

I haven't had a floppy disk in my hands for 19 years and they were shitty 2000 already.

I also guess even less people are even getting anything out of floppy disk comparisons.
> realizes, ‘Hey, I’m the one that’s responsible,’” Kornhauser said. “Just like when I was driving a ’55 Chevy”

Um, no shit the driver’s responsible. This seems like a weird question to be confused about prior to level 5, which Tesla’s 2022 “full self-driving” isn’t and 2019 wasn’t either.
Of course he's liable. He should have been driving. Fully autonomous cars aren't yet legal for anyone to drive autonomously, the driver still is responsible.
This dichotomy of gifted/not gifted learners is heavily biased on what you see is all that is and ignores the cognitive medium, the water we all swim in and through we all interact.

Yes, as s private tutor (mostly for maths) I witnessed young people (1 of 10) who are not only exceptionally fast at grasping abstract concepts but in the same breath can actually use them to infer/deduce correctly (at times in new ways).
In that case I have to switch gears to keep them excited but at the same time rebuild their formal foundation which is weathered through the school system (strechted in time beyond recognition and disintegrated in small "digestible" pieces i.e. uncomplete or no proofs at all) without hampering their great intuitions, a very difficult task.

That being said from a purely cognitive/neurological perspective the possibilities in "wiring the brain" are for all intents and purposes the same between healthy newborns.
Our culture tends to overemphasize the little differences which has its upside in empowering the individual (very important!) but its downside in the indifference of the overwhelming similarities.
Once I positively acknowledged the (nearly identical) neurophysiological start parameters in every human especially during the critical period from birth to adulthood, it changed my whole attitude. It is like realizing we all share the same very recent - in evolutionary terms - African origin, it puts relatedness into perspective.
From that vantage point I feel much better equipped to appreciate the wonderful individual differences and discover the light and shadows of giftedness in every learner without the need for them in participating or winning math olympiads, international music competitions, chess tournaments, gymnastics championships ...

Being familiar with the empirical example (admittedly small in sample size but nevertheless what are the odds?) of Judith Polgár [0] the impressivness all nearly lies in the determination of her father's experiment without having to resort to some dubious concept of "giftedness".
This of course does not imply we should all teach everyone the same, but - quite the opposite- to the needs of the young (hearing them out), that's were I agree in conclusion but without the needless distinction between some upper limit of gifted and not gifted.

That's an opinion not a statement of current policy or reality.

In the real world we have pretty extensive precedents about consumer product safety, and manufacturers are very often liable for design decisions that lead to harm, even if nominally speaking the user was supposed to be ultimately responsible.
Agreed! Next time I will gather more arguments.
False dichotomy. We can and do already have both, on multiple forums, and even on the big social media platforms. That's the case despite there being a few large entities, just as small restaurants continue to exist despite the existence of MacDonald's. The premise that "centralization" of the internet through FAANG gatekeepers forces people to adopt either one or another model as universal to either accept or reject those gatekeepers is fallacious. Centralization of attention isn't centralization of the network.

If this trend of fact-checking causes too much bad press and hassle for social media platforms, then platforms will simply stop fact checking or people will turn to alternatives. But the internet isn't going to turn into an Orwellian thoughtcrime dystopia nor will it turn entirely into 4chan.
It's intentionally built to be crap. If your requirements are constantly changing, you want to be able to turn on a dime. If you have "nicely architected" software, that's going to be a lot of work. If the "software" is just a folder of Python files and some shell scripts, adding in some hack to meet some business need is very quick work.

In mathematical terms, the ratio of A - the amount of hours spent writing the software to B - the amount of hours spent running the software is going to be very high. It doesn't make sense to spend two hours to fix a bug, if you can just spend ten seconds applying a workaround, unless you'll run it more than 720 times within its intended design lifespan.
It was interesting. Good to see the sources cited :) Then I got to this:

> there is compelling evidence [1] that such extreme weather phenomena are becoming more common [0].

The links looked interesting, so I followed them. The second one was an abstract [0] saying, basically: "the last 50 years have seen more of these types of events", fair enough. The first one [1], though, had a paragraph that stuck out to me (apologies for the long quote):

> “It’s tough, though,” Butler continues, “because we don’t have a very long record of observations of the stratosphere. We’ve only been observing it directly since the 1950s. That’s not very long to understand what kind of natural variability the polar vortex might be capable of. One researcher did a historical reconstruction by correlating the overlapping portions of the North Atlantic Oscillation index—which goes back much farther—and the polar vortex record, and then extrapolating the polar vortex record farther back in time using the NAO index. It showed no long-term trend, and no big differences in recent decades compared to previous decades.”

and then near the end, as the conclusion:

> Still, by most of the metrics experts use to describe winter climate, Overland agrees the big picture is clear: on average, winters are warmer and cold extremes are less likely than they were a century ago.

How is this article cited as evidence that extreme weather phenomena are becoming more common? How is the science.org article able to claim that there have been more in the last 50 years when we've only been observing them for ~70 years?

Anyone able to shed some light here?

Do you have criticisms of the feature or is this facile cynicism?
Do we hold pilots accountable when the plane in on autopilot? Genuinely curious.
Out of curiosity, who and what on Slack, Twitter and Mastodon?
