I won't disagree that the data could be better. It can always be better. But it gets better. With every. single. update.

You're just wrong about no ways to use this data. I've personally dramatically improved my health via wearables over the past 7 years. A close friend with a heart condition has perhaps had his life saved by these things. Check out the FitBit forums or subreddits. When you have a lot of data with high dimensionality and apply modern ML/DL methods you can discover connections that just aren't visible with fewer dimensions.

I though you were talking specifcally about the low-power cores (and I couldn't find a site specifically comparing those, but even you could find those, it would be a weird niche (micro) benchmark, because it's not clear if those cores are used like that.

In any case, the link you shared (https://www.anandtech.com/show/16192/the-iphone-12-review/2) backs up what I said; the overall SoC perf of the 865 is quite close to that of the A13 (which is it's same-gen competitor). The specfp score of the 865 is 74% of the A13; the specint 64% (the 865+ is 3 percentage points better here). And the joules consumed by the A13 is significantly higher than the 865 for both benchmarks (the 865+ uses more energy than the 865, but less than the A13).

In fact, the geomean of perf and power between A13 thunder and lightning cores is pretty close to on the money for the 865, for both power and perf!

All in all, the 865 looks pretty competitive in the benchmark you linked; pretty much smack between the high-power and low-power cores of the A13: more efficient than it's high-power cores, but slow, and faster than the A13's low-power cores, but less efficient. Unfortunately, the page doesn't include the 865's low-power cores in the benchmarks, but from the point of view of disproving the apple-domination story it doesn't really matter: clearly competitors can build cores that are close to the cutting edge of apples power/perf tradeoff; they just choose slower, more efficient designs.

Where are you getting a 4x improvement in performance?
> I feel like a lot of today’s mistrust of news stems from publications not verifying sources

First, a nitpick: that is a thought not a feeling: you didn't state how it made you feel, you stated an idea.

Moving on... That's not why people mistrust the media. They mistrust the media because they are told to by politicians seeking to discredit journalism and control the narrative.
Back to ext4 because btrfs had crazy bugs?

ext4 had at least two critical data corruption bugs in the past 5 years in stable kernels (personal anecdote: one ruined the root filesystem on a server that I used, after which I stopped using ext4).
It's def a slippery slope, but all of hiring is bound by implicit bias. If random people are evaluating random people against a set of subjective metrics, you're always going to get _some amount_ of bias in your decision making.

In reality, I think a surprising amount of bias goes into "tech screening", maybe even moreso than evaluating "soft skills." If you're asking random engineers at your company to conduct tech screens, the odds that those engineers are emotionally and mentally reflective enough to be fair and bias-free in the questions they ask and the solutions to those questions are very low. This is why so many places struggle with tech interviews that feel like debates. Engineers dislike candidates that do well on the tech portion of the screen because those engineers feel it is a competition that they must "win". I've seen this time and time again at FAANG and non-FAANG. Random engineers from a team should not be assessing candidates, pretty much ever.

Yes, that is what I alluded to at the end. There's a few points here that still need some interop work. The intention is to fix that, but it's non-trivial. We'll get there.
Sure. It's like the part in the movie when the ax murderer invites the young coed into the dungeon-like basement.

It hasn't happened yet, but you know how it's gonna go.
Fair enough.

I thought it was targeted more towards the general population. I was a bit too harsh.My apologies.

The harmful bit was because I read it as though you were preaching rather than talking about intensely personal choices. With that qualification, my statement of it being harmful was unwarranted.
I think it would just smoke you from the outset. As far as I know it doesn't have a structured intelligence it can scale back - it would make the optimal move every time, destroying you like it destroyed top-tier players.

Comic Sans and its descendants are... indestructible. No matter how much some font designers complain about it, and how often they criticize it, Comic Sans keeps coming back, like the Terminator: https://en.wikipedia.org/wiki/Comic_Sans#Reception_and_use_i...

Among the most incongruous uses of Comic Sans I've seen, a few stand out:

* A plaque on a large statue of a historical figure in a public space: https://www.biobiochile.cl/noticias/nacional/region-metropol...

* A letter announcing the creation of new political party in Greece, breaking off with the then-current Prime Minister: https://web.archive.org/web/20151004131442/http://www.volosn...

* A letter to the US Congress from the legal team defending the President against impeachment proceedings: https://www.fastcompany.com/90414127/trumps-old-lawyers-real...

Thankfully, in these examples the authors chose not to use a different color for each letter!
What I don't see in this comment is an acknowledgement that for all practical purposes (besides niche venues like IBKR Pro) all retail order flow is done through brokerages that do PFOF. Can you be more precise about what part of Robinhood's "model" you're talking about? Depending on what you mean, I might agree with you, or I might strongly disagree with you. Does your critique apply to all brokerages, or Robinhood in particular? If it applies to everyone, what does it matter what the SEC says? The SEC doesn't have any problem with Schwab.
On a slightly related note, I really am enjoying the browser extension "remove youtube suggestions" My home page and completely blank and any video that I watch has no recommendations on the side.

Show HN: Cryptomas Cards – Create holiday-themed crypto gift cards
> 13 Taming circular type dependencies

I really despise the 'common' module approach because it scatters code that should be in the same file.

One workaround I use to avoid this is to break the cycle of type dependencies by replacing one of the dependencies with a generic parameter. This works great if the type that has a generic parameter only deals with opaque objects of that type.

Once concepts are fully supported (they may already be now), this pattern will be able to describe more complex relationships.
> Session-based Auth

> It's stateful. The server keeps track of each session on the server-side. The session store, used for storing user session information, needs to be shared across multiple services to enable authentication. Because of this, it doesn't work well for RESTful services, since REST is a stateless protocol.

What stops you from keeping the JWT token in there? In fact, I doubt that it's some random session ID and not some encrypted payload that gets decrypted instead of looking it up in the database.
This is technically neat, but I really wish that browsers would just have a config option that would allow me to turn on trust on first use for certs. Also, all other software that use TLS.

It works fine for mailservers. No on expects a mailserver cert to be from an authority, you can self sign and it works fine.
Rationalist circles make just as many horrific logical errors. If you want to dig into this stuff philosophy has dug deep, and frankly all they came up with is all sources should be treated as suspect. Aka, even if a source got the stuff you know about right, you should still be be skeptical. And yes, that includes purely logical reasoning about math.

It’s not a satisfactory answer, but ¯\_(ツ)_/¯

Hey, HN--author here! Sharing this site I hacked together over the weekend--I wanted to send my friends crypto for Christmas this year but couldn't find a good solution, so I made my own!

The site is essentially a multi-currency paper wallet generator. All keys are generated locally on your computer and are never sent out (you can verify this by monitoring your network requests, or turning your wifi off once you load the website and turning it back on once you've closed the site).

All you need to do is pick a theme for the card, add the cryptocurrencies you want, and optionally add a message. From there, you can print it out or send a shareable link. The links themselves contain all the information needed the render the card--again, private keys are never collected or stored.

Hope you enjoy! Maybe this'll be useful if you're looking for that last-minute gift ;) Happy to answer any questions here or on twitter @iamtonypeng!

The most scarring interview experience I've ever had was with Amazon, when I was very young, where they exhibited a similar amount of not listening to me at all and evaluating skills that I never claimed to have.

Ultimately Amazon is too big and too popular to listen or care to candidates. They're going to do whatever they're going to do, regardless of what you say, and that'll naturally filter out a ton of candidates.
I truly don't understand why. Are people just that sick of Times New Roman and Calibri? It's not like I especially hate Comic Sans, but it seems so wildly inappropriate for all of the uses mentioned above.

This was my title at my last job. It's just the title for coders. Nothing more. I think it's a bit pretentious personally, so I usually just say programmer.
This would be one of mine too.

I remember reading a (speculative) argument that the earliest gospels were much more ambiguous about the "miracles" and exactly what happened after Jesus' death. Was the account of seeing him rise to heaven a later addition?

Likewise I'd also like to see what the real Christ had to say (if he did in fact exist - that's still disputed AFAIK). I've always liked to imagine he was much less spiritual and more political. I imagine there were a few other would-be messiahs doing the rounds, I wonder what they were up to, and how similar they were (I think we can be confident they were about because the New Testament does mention them - albeit very unfavourably).

Another time / place to go would be when the first books of the Old Testament were written. There's a theory doing the rounds that the first book written was Leviticus, which acted as a kind of early legal code. Then the theology was added later as a means of justifying the law and marrying it to a religion rather than just a city state. There are also arguments that early Judaism was polytheistic and Yehova was a god of a city rather than "the god" in the original conception.

I've always been curious about the origins of those belief systems and how close our Bible reflects the actual beliefs and cosmology of Iron Age proto-Israelite society.
I already know, you're missing the point.

I love React and JavaScript but I completely disagree with this. I've moved to Django for my back-ends and it's an infinitely better experience than any Node.js-based backends. It provides a structure and set of facilities which are completely unmatched in the JS server world.

I would only use Node.js again for the back-end if I explicitly needed its performance characteristics.

You could be right. I am also worried about a FitBit under Google. But no one came up with a better alternative and the competition was too great. I would have loved if FitBit could have remained independent. It would have taken a true believer like an Elon to make it happen.
Wow, cant imagine being in your situation. I would say try to ease yourself into lowering your dose slowly. I am not sure if its even possible with your situation but with IBS I try to control everything else including stress, food and sleep. I take loperamide if those dont work and it allows me to reset myself into being normal for sometime, that way I can retry. I try to go as long as I can without one and see if I can push myself. But I dont get too far due to work stress anyway.

Honestly the whole thing about people abusing it and FDA clamping down works against normal people who are genuinely using it.
Mmh, Python 2... The troll goes deep, love it.
Which is indeed the case for us. We are (I am) based in Ireland, and there is a significant time different. Even though that's not the main culprit here but still applicable.
The economics don't quite work the way you describe.

The brokerage is forwarding your flow to one of it's partner broker-dealers who is providing the actual execution service. Those BD's would happily take this flow for free (as evidenced by the fact that they now _mostly_ pay for it). The executing BD, not the brokerage, is on the hook for trading fees _if_ they need to execute the order in the public market - which is rare as they mostly internalize that flow. The executing BD's business model is based on the assumption that the flow is not particularly toxic and that at scale, the profit margin per share exceeds any execution costs.

The larger point stands though: from the perspective of the executing BD the payment for order flow + price improvement are both costs, which they want to cap. If you dial up PFOF, you naturally get less price improvement.
As someone who knew Durov personally, I'd say that it's very unlikely that the UX will be ruined by ads, and even more unlikely that users will be manipulated and/or tracked in any way. If there's one thing he does well it's respecting his users. He knows what "we're earning enough to cover our expenses" means. The company is privately owned so no one will be pushing him into anything either.

Many popular Telegram channels already have ads in them, posted by their creators. My understanding is that Telegram will be taking control of this by acting as an intermediary, taking a cut and possibly deciding what goes through. Thinking of it, it makes sense, and doesn't alter the UX at all for the average user.
Yep, which means he effectively doesn’t own them right now, in any meaningful financial sense. For the purposes of control, sure.

This will do great harm in markets where there are no protection for health data.

Health insurers in my country(India) are already discriminatory, top health insurers here denied me health insurance because I disclosed my disabilities[1] despite Govt. guidelines against blanket denial of policies for the disabled. This is pretty much the case for anyone who discloses their disability truthfully here[2][3].

This is because they're not keeping in sync with the progress in medical science, why should my orthopedic troubles be a risk factor for providing insurance to cover COVID-19 treatment?

Now with say health data from devices, they'll likely find more statistical data to deny coverage (with some obscure reason) or increase premium to many even if the applicant isn't sick and thereby denying a chance of health insurance coverage if they really get sick. Especially when an unqualified underwriter decides whether I should get a health insurance or not.

Used to have IB: that broker is no joke. I would see ads on TV of $7 a trade while I was paying their crazy .001 cents per share or whatever their price was. Great paper trading account, and a Java/C++ API for everything. Plus level-2 data.

These kids with their RH accounts have no idea..
I agree with this.

I would add, these holier-than-thou FAANG interviewers writing blog posts about how to clear a FAANG interview are actually bullshitters. They want to feel good about themselves. So they write.

When push comes to shove, these same interviewers would clear the candidates who've pretty much memorized all the medium-level leetcode problems, but lie during the interview by claiming that they've never seen the problem before in their lives, but just happen to be "so good" they end up solving the whole thing in 30-35 minutes.

P.S.: The non-tech part is not that hard. Just don't be a dick.

>As if checksum collisions aren’t something that state actors could trivially create [5].

>[5] https://shattered.io/

Collision attacks are an issue when using md5/sha1, but I don't see how it's relevant in this case. If state actors wants to replace the signal apk with a backdoored one, they'll need to pull off a preimage attack, not a collision attack. A collision attack wouldn't be useful because you still need the original publisher to sign the apk for you, which seems unlikely considering OWS isn't a CA or anything. If OWS was compromised by state actors into signing, then they can just sign the backdoored version directly, no need for a collision attack.
Yea atleast from personal experience with n=1, I think it does affect cognition and honestly I am glad it works that way and I discovered it lol. On other days when IBS is in full effect, I dread doing any work and have zero focus.
+1. If what they were working on was not Signal but some proprietary applications (possibly with DRM), the hilarious blog post on their "code cracking" effort can actually be a legitimate one. In principle, the process is the same - break into something when you are root already. The only difference is the challenge of code obfuscation - which is a real one, unlike Signal.

Could be it doesn't work as well; while obviously eyes can move in n all directions, it's possible long left-right sweeps with small up-down adjustments are more natural/comfortable than swapping the axes.

Certainly horizontal scanning seems to be more a common activity generally, so it would make sense for it to be favored.

Ask HN: What are some concrete examples of good SPA's?
Hi all,

One of the arguments I keep hearing being said on Twitter and Hackernews is you should use React/Angular/Svelte when you have an more 'appy' website but I can never figure out what is meant by that.

Can we have some examples of concrete sites that are actually benefiting from SPA frameworks and would be infeasible in a typical Rails/Django/Laravel setup.

Anyone know of any resources taking a reference point of a more complex user interface and implementing it in both React and templating with Rails?

Turbolinks for me has fixed the white page refresh issue and Hotwire seems to have unlocked a few more interactivity tricks CRUD things, see https://twitter.com/noelrap/status/1341520142258348035.

But I'd like to know what interactivity I'm missing out on.
