On child #2, can confirm. We actually planned for it. By planning for no activities. Just bunkering and resting for 2 months straight.

We began partial daycare on Thursdays + Fridays in winter. Daycare is like Cancun for bacteria. Dry cold can weaken the skin, and cold is good for bacterial protein stability.

The cycle begins: kid starts incubating on Thursday. On Saturday he's sick, and you hope for a good lottery. Diarrhea? Puking? Maybe not. But a runny nose most probably. These may ruin your nights, still.

Sunday they are sick, and you begin to feel unwell. Monday the kids is recovering, but you're still in it. By Wednesday you should be good though. And then it's Thursday again.

On another topic air filtering is great for the kids I'm sure; but I can't help wonder if it's just kicking the can down the road.
Show HN: SerdeV – Serde with Validation
A serde wrapper with `#[serde(validation ...)]` extension for validation on deserializing
This is perfect, thanks!

... well except it stores up to 15 bytes inline rather than using the UTF-8 trick to cram an extra byte. (But maybe it can't; or at least, ByteYarn really can only store 15 bytes, even though Yarn could store 16 bytes maybe, but this would pose problems when converting between those types because I suppose this conversion is zero cost)
Although I'm not on the super sweaty side of trying to grok some of those items in your list, I have been going back to square one from the perspective of having started with and followed the whole dependency tree of frontend but never understanding the really low level.

Over time, I've learned to appreciate getting "reps" in whatever subject, and just sitting with it for ages and grinding your brain into dust trying. Something I've also been noticing now in my 30s, is that your and my ability to do that is something to be proud of—even if it won't come as fast as for someone innately faster or with more prereqs—because many people are truly not curious and don't push themselves. The amount of otherwise smart people even that won't or can't sit down to learn something for curiosity sake, and I'm not talking something very long-term like game engines, is... like next to zero people.

And it not just true for learning hard or impractical subjects, but the overwhelming majority of the surprisingly high number of decent friends I have, do not have the patience for pushing themselves and will bail on hard physical activities as quick as possible, even if they're pretty fit. It's quite eye opening. They tell me they want to go do __, but not if they can't squeeze it in to an afternoon, even if they definitely have the time, and it really detracts from trying to share the experience or curiosity.
I wouldn't call this a statistically significant result, and the fact that the buildings in question had good mechanical air ventilation could very well explain the results:

> "Utilizing the model, we used portable air cleaners in two day care units (A and B, number of children participating in the study n = 43) and compared infection incidents between the two intervention units to the rest of the units in city of Helsinki (n = 607). The intervention buildings had mechanical supply and exhaust air ventilation."

https://www.sciencedirect.com/science/article/pii/S295036202...

You also have to consider external air quality, as ventilating a building with polluted air would have negative effects like increased asthma. In that case perhaps a sealed building with air purifiers is a better option, but then CO2 buildup is a concern, so you'd need CO2 scrubbers, which are expensive.

That's why clean air regulations matter, and getting off fossil fuel combustion as an energy source (and limiting pesticide/herbicide use in agricultural zones) is the easiest route forward.
Many defend Telegram by likening it to a neutral platform, akin to TCP, claiming it merely provides a service without responsibility for the content. However, this comparison fails because TCP is a simple protocol with no ability to control or monitor content, whereas Telegram holds keys for most data and is capable of content moderation. Unlike E2EE platforms like Signal, which cannot comply with requests without breaking encryption protocols, and whose jurisdictions often prohibit forced backdoors, Telegram's refusal to cooperate, despite having the ability, shifts it from being unable to act to willfully aiding or sheltering criminal activity.

In this context, Durov's arrest isn't unjust - Telegram knowingly allowed illegal content to thrive while ignoring legal obligations to assist law enforcement. Refusing to provide data when you can, under lawful requests, is tantamount to facilitating or even protecting criminal activity. This dismisses the complexities of cross-jurisdictional law enforcement, but the general concept remains valid.

By the way, I’m not a fan of censorship, but I do believe that a platform’s baseline for moderation should be compliance with the current laws in each jurisdiction, rather than the founder’s personal moral judgment.
Hi - Who is 'we' and how can I get involved.

I tried to build this after leaving Lockheed in 2007 where we built the RFID tracking for .mil as Savi Networks..

All the cell integrations (pre IoT) were cost prohibitive.

Its wonderful to see how much has taken place in this area since a bunch of us tried and failed to get funding back then :-)
Apple Approves iDOS Emulator
I am a front-end developer, and I am glad to chat with you here.
I had the same problem as you before, so I also built many blogs. Recently, I open-sourced a blog project named DevNow based on Astro. You can find it here https://github.com/LaughingZhu/DevNow . The content of the article can be md/mdx. I recommend you to use .mdx, which can better support some advanced features, such as media embed, callout, copy code, etc. The project supports vercel for one-click deployment. You only need to write .mdx content in md format in vscode, and then push it to github. Vercel will redeploy itself. If you are interested, you can try it, but the unfriendly thing is that the comments used in my project are mostly in Chinese. If you are interested, I am happy to provide some help.
No. Your source makes clear that Marconi sent the first message (Tesla failed to send a radio message in 1895, Marconi succeeded). Read "My Father Marconi" by his daughter Degna. Fantastic book.

Other than that, a very fascinating read, the link you shared. Patent stuff is silly, but were way less silly back then, and had more positive 2nd order effects back then.

It was cool how Tesla and Marconi held each other in high regard, and built on each other's works.
Worse still, we lead kids to believe that 'doing math' is performing computations. And so even many kids that can calculate passably grow up thinking that 'math' is boring and they hate it.
Riot: An actor-model multi-core scheduler for OCaml 5
No idea. It seems to have gone off in the direction of "shiny and new" without deeply considering more practical architectural decisions like isolating system vs. userland, configuration management, or manageability. It's unfortunate because there are zillions of Linux distros, and most of them (numerically) are terrible, insanely impractical, user hostile, and/or poorly documented. If you're going to create a distro, at least have a use-case justification for it where other distros or other OSes ([wd]o|ca)n't meet the needs of them adequately.
Robotics is way too hard and they should look elsewhere IMHO.

Software has this beautiful property of being magical: if you can imagine it, it can be written, given sufficient effort.

The physical reality puts constraints that you often can't work around with decades-long, distributed research... which isn't really profitable or timely for a business to do.

There are countless cases of companies trying to "solve" problems in the physical world with ingenuity carried over the virtual one. Self-driving cars come to mind as one topical and recent example, even if I do believe in their success in the long enough term.

Sometimes examples are more catastrophic failures, like Theranos... which is why I'm generally short on promises of "healthcare tech" in general.

And as much as I enjoy my Apple devices and appreciate the second-to-none ingenuity of their hardware, I think a lot of their value proposition comes from software. They would do well to refocus these greenshoot innovation efforts to software categories that are dominated by subpar experiences and reinventing them from a fresh perspective. Easier wins and no shortage of profits to be made near term...
Why are these service providers being punished for what their users do
[...]
maybe I'm just being naive?

In this case, the comment does strike me as naive.

Back in the 1990s the tech community convinced itself (myself included) that Napster had zero ethical responsibility for the mass piracy it enabled. In reality, law in a society is supposed to serve that society. The tech community talked itself into believing that the only valid arguments were for Napster. In hindsight, it's less cut-and-dry.

I have never believed E2EE to be viable, in the real world, without a back-door. It makes several horrendous kinds of crime too difficult to combat. It also has some upsides, but including a back-door, in practice, won't erase the upsides for most users.

It is naive to think people (and government) will ignore E2EE; a feature that facilitates child porn, human trafficking, organized crime, murder-for-hire, foreign spying, etc etc. The decision about whether the good attributes justify the bad ones is too impactful on society to defer to chat app CEOs.
Finding a therapist who takes your insurance can be nearly impossible
This oversimplifies the original idea behind what you're trying to recall. Being sick in and of itself is not the beneficial part, it's exposure that can be beneficial in certain cases. If you can get the exposure without actually falling ill it's all the better, it's a win-win. Note that not all exposure is good, for example you never want to be exposed to the bubonic plague if at all possible.
My current project is TrendBowl (https://www.trendbowl.app) which summarises trending entities across multiple sources on the web, including Mastodon and Wikipedia. On a 24 hour basis you can see which terms are relevant in different languages and sites.

It is implemented in Go, Python and JS, with support from Postgres, TimescaleDB and Kubernetes.
To see the brilliance of advanced ideas, you need to be quite advanced yourself.

What you wrote is analogous to saying that playing football in the Premier League is nothing special compared to me and my weekend buddies playing in the yard, it's still human beings kicking a ball, just with better coordination and strategy. Yeah. Coming up with new math at a research level is also just manipulating conceptual objects in your mind. Except this insight doesn't make the average person capable of either.

For some reason people have a big hangup around admitting that some people are more talented at abstract thought and advanced math than others, even though this is absolutely obvious even to a schoolkid. The existence of the Premier league in no way diminishes the value of kicking the ball with friends over the weekend. Math can be fun in the same way, but not everyone will reach the same levels.
An open source US president election model from polling data
I don’t know the dbus crate, so I’m not trying to say anything about that crate’s usage, I’m simply saying that referencing after dereferencing is idiomatic Rust.

For example, the standard library `String` type dereferences to `str` which you can then re-reference to `&str`.
A anecdote about Pavel in a HN comment from few weeks ago (not that I have a stance anything in this situation):

https://news.ycombinator.com/item?id=41149755
We also have e.g.:

When it comes to Jewish settlements in the West Bank, 40% of the public say they help Israeli national security, while 35% say they hurt. An additional 21% think settlements don’t make much difference to the country’s security.

https://www.pewresearch.org/global/2024/06/20/settlements-an...

Plus there's the fact that the country, despite all its internal divisions, managed to put a certain Benjamin Netanyahu -- who has declared the expansion of the settlements to be a "top priority" -- in office 3 times (for some 17 years total so far). And all the mainstream society hate for Oslo and 2SS, and so on.

These are just a few of many obvious indicators. Of course many feel conflicted about the settlements, and only support them the perceived "security" advantages, and so on. But it's just not tenable to say that the settlements "don't really have mainstream support".

When by all indications, the imperative to support and maintain them has been national consensus for several decades now.
The Origin of Gravity and the Laws of Newton (2010)
Could this be combined with masks for greater efficacy?
This was my takeaway from college. In HS, you don’t have a lot of prerequisites, excepting the “II” level classes. I quickly found out how unstable my math and physics foundations were. Luckily, few realize that Bs are closer to failing than they are to mastery.

Even the college gut courses have hidden dependencies. I still feel for the business majors in my entry level stats class when the prof, bragging about learning calculus at 10, required calculus proofs for all the things.

Much like Civilization and Diablo games, and @godber’s comment, those tech trees should be required for all course syllabuses.
> It's not. They use a split-key encryption system so it's not exactly the same as storing the keys where the data is.

Yes, again, it all comes down to your threat model. No one can kick down the door and get to the keys.

But Telegram can get to all the keys, and thus can be legally expected to. The data is effectively plaintext to Telegram.

> Is MTProto 2.0 Cloud Encryption plaintext? No.

Just to note: "effectively plaintext" has been in use for a couple of decades as a term of art. We don't say it's plaintext, because it's not. It means there's effectively no security properties lent by the encryption.

For example, my web browser encrypts a few passwords for me and stores them on disk, but doesn't need a cryptographic secret from me to decrypt them; they're effectively plaintext, because no one has to break any encryption to read them.

Indeed, here's a thread on HN from 2013, where Durov is participating, where people are using "effectively plaintext" in exactly this way to describe exactly what we're talking about: https://news.ycombinator.com/item?id=6937097
Improving the human condition.
His intentions could be interplanetary expansion, profits, or more likely both. It doesn't matter. At the end of the day we now have reusable rockets and starlink thanks to this.
>The "170%" number is bogus.

Actually, it's 253%. I made a mistake assuming the 890M was limited to 35w. It was actually 46w as measured by Notebookcheck.[0]

>Reducing the power of 890M to 17 W, the same as quoted for M3, would reduce the performance much less than the reduction in power consumption, improving the energy efficiency.

That depends. Sure, give almost any chip less power and it will be more efficient. I'm not arguing against that.

The problem with reducing power for the 890M is that it's already slower than the M3 by 26% while using 2.7x the power.

If you give the 890M 17w, yes, it will be more efficient than 46w. It just just be even slower than the M3.

>The better performance of the Apple GPU could be entirely caused by the much higher memory bandwidth

M3's bandwidth is 102.4 GB/s. AMD Strix Point uses LPDDR5X-7500 in dual channel mode so it should be around 120GB/s.

>and by the better CMOS process used for the Apple GPU.

AMD's Strix Point is manufactured on TSMC's N4P. M3 is on N3B, which is roughly 10% more power efficient than N4P. It doesn't explain the huge discrepancy in efficiency.

I've actually given up trying to post on Reddit for this reason. Whenever I've tried to join in on a discussion in some subreddit that's relevant(eg r/chess) my post has been autoremoved by a bot because my karma is too low or my account is "too new". Well how can I get any karma if all my posts are deleted?
Every person I see working retail has an Apple Watch. Think it’s some weird mix of they can’t have their phone and also rampant materialism through exposure at work.

I loved my $30 EBay Apple Watch as a cheap running watch with GPS before the battery got so weak it wouldn’t even do my 1.5 hour runs anymore. Apple wasn’t helpful about a battery replacement and encouraged me to buy a new one (starting at $249) and said they couldn’t replace the battery since it was so old, when I met a Genius at the Apple Store. That soured me quite a bit on the whole thing.
I'm speaking more generally than git here, part of being any type of inventor is to simplify for the user and make it intuitive, that way if the internals change, the abstraction/external look the same.
Let's travel back to 2016 ...

> It does feel like Apple innovation is either stagnating or small, incremental gains. Certainly not huge leaps like iPhone or iPad. Apple Watch hasn’t really taken off yet.
You are assuming this is purely a French endevour.

I am assuming the opposite.

Maybe you forgot how us democracies work together for good and evil.
They shot themselves in the foot with eSim for Apple Watch (Samsung did he same with Galaxy Ultra watch). You have to buy a contract for both your iPhone and your watch, because you cannot put your Apple Watch on a pay as you go plan. This is a big obstacle in Europe where PAYG plans are popular. It's not going to change, because operators like it and LTE smartwatches do not cut into smartphone sales.
Read the founder exit letter. whatsapp is definitely not e2e encrypted for all features.

You leak basic metadata (who talked to who at what time).

You leak 100% of messages with "business account", which are another way to say "e2e you->meta and then meta relays the message e2e to N reciptients handling that business account".

Then there's the all the links and images which are sent to e2e you->meta, meta stores the image/link once, sends you back a hash, you send that hash e2e to your contact.

there's so many leaks it's not even fun to poke fun at them.

And I pity anyone who is fool enough to think meta products are e2e anything.
Which environments/systems have you tried?

A search of your site doesn't have a match for "Literate Programming" --- I've found it a benison when developing, esp. in that it allows me to review code which already exists, and to create a structural index while writing which allows a quick/easy check if a given module already exists in a context where it should --- managed to make a system for this w/ a bit of help from generous folks on tex.stackexchange:

Let's take an example: protecting a car. There are countless possible attacks on the software that runs automobiles, but the most common attacker goal is to steal the car. That means you want to protect the paths to that goal, regardless of what they look like or whether they are even specific to software.

Sure, attackers can also exploit CVEs to DOS the entertainment system but who really cares if that happens?
Neutron stars are the literal limit to how much matter can be collapsed before it turns into a black hole and yet still remain a star.

A neutron star 12-16 miles in diameter contains the mass over HALF-MILLION earths, it is very hard to fathom but yet they exist!

So popping out an earth-sized chunk of gold after collision with say another neutron star (kilonova) and ejecting matter to "normal" density is plausible.
That sounds wild. I don’t know where you are but in the USA you could reach out to a university extension program/office and ask them to look into it. It’s bizarre enough to catch their interest and come at no cost to you.

Edit: it really is bizarre because Radon is primarily produced by reactions underground/in the earth and has a relatively short half life (3.5 days). I don’t see how it could be atmospherically sourced without it being a hazard to the whole community, regardless of the bizarre convection currents that bring it into your house. It’s unlikely to be produced in your attic.

If I were you, I’d want to know more and understand how this is all happening lest you raze and rebuild and find you still have a problem.

> The answer is it's faster and (in my experience) generally accurate for common command syntax.

If you don't mind, around what level of complexity are you querying it for? Are the queries along the lines of "how do I find a keyword in a directory in UNIX?" or more along the lines of "write a bash script that will do foo recursively and treat edge case bar by doing baz"?

In my experience, if the queries are closer to the latter, it takes less time to "man page" the holes in my knowledge than to identify and to fix whatever is wrong with the LLM's initial guess. If you more often than not receive correct answers, even in non-trivial cases, could you please provide the LLM and any custom parameters if they exist? I'd be happy to be proven wrong and learn something in the process.

> Googling is very hit or miss these days you end up with a load of sponsored results and then have to try and find an example with ideally the exact syntax you're looking for.

May age be a factor here? I grew up as search engines were becoming a thing and ignoring "fake" results has become second nature.
This might be true on the user-facing side of things, but moving chip design in-house and transitioning their entire hardware lineup to the ARM ISA is a big innovation. M-line Macs can't be beat in efficiency or performance any time soon.
I've been working on Lorcast (https://lorcast.com/) a Scryfall like search for Lorcana. Scryfall offers a powerful search engine and query language to search for Magic: The Gathering cards. Lorcana is a new card game by Disney that also has a competitive scene. As the number of cards grows it will become more important to have good search _and_ good APIs for the community to build with.

It's been a breath of fresh air to work on something that I have no plans to monetize. I just want to build something useful for the community to use and that has allowed me to be relaxed with building it.

Anyways, if you play Lorcana I encourage you to check it out! The game is lots of fun.
