Several comments here mentioned shift work as a possible explanation.

The paper concedes that shift work is unhealthy[1] but claims that shift work doesn't explain their finding[2]. And their conclusion is "avoiding night light may be a promising approach for preventing cardiovascular diseases," but without telling us why. It's going to be fascinating if there's a mechanism by which sleeping with light can cause heart disease.

[1] "Evidence demonstrates higher risks of adverse cardiovascular events, coronary heart disease, heart failure, atrial fibrillation, and mortality due to cardiovascular disease in rotating shift workers."

[2] "Following separate adjustments for pre-existing diabetes, hypertension, high BMI, high cholesterol ratio, short, long, or inefficient sleep, and exclusion of shift workers, the relationships of night light with cardiovascular risks were attenuated but remained statistically significant for all outcomes except stroke."

At that age I’ve had great success with simple sports toys (wiffle ball set, or toddler sized soccer ball and net). Those little two-wheeler bikes that start without pedals and can have pedals attached once she masters the walking version. A wagon. A beach/sandbox sand toy set.

Also those Brio wooden train sets. And magnetic blocks or wooden puzzles. Any type of building set accessible to hands that don’t yet have precise control. Basically something tactile that helps them engage with the physical world.

She’ll also be learning to identify numbers and letters and mastering colors and shapes. Kids that age LOVE learning if they’re encouraged in it and it takes the form of play. The more open-ended the better.

If her parents read to her on a regular basis, she’ll probably love new books. At this age, think Dr. Seuss and Where the Wild Things Are.

Expensive digital stuff adds very little compared to simple open-ended timeless toys at that age. Some of the best gifts are very inexpensive — crayons and coloring books. Bubble wand and soap. Alphabet magnets. A bucket of plastic zoo animals. A doll or plushie small enough for her to carry around with her.

Consider getting something inexpensive that will delight her and then ask her parents what they wish they had $150 to spend on for her.

I avoid LLMs so I have not bothered with MCP, but what you need is trivial. Node provides multiple ways to connect to local services like IPC channels, network sockets, child process and more.

I recommend using the child process spawn method to create the MCP service behind your node based web server. You would write to stdin.write of your spawned process and you would read from the stdout and stderr data events.

The slope isn't slippery, it's paved with a Starbucks on the way. This process is outlined in detail in Project 2025 to get around 1A being used as a defense because the aim is to define anything as lgbt related as pornography.

The current administration has collected nearly all the pieces of Exodia to be able to legally criminalize homosexuality and transgenderism without ever writing a law that says those exact words and have it be held up as constitutional. I'd say it was clever if it wasn't awful.

Its really sad to see this getting attacked, now, after all that's transpired, after so many years. You'd think if it was that dire, again maybe 10 years in there would have been more action. But again its not genuine, so its really about the ulterior motives. Not even to mention the 1st amendment issues, which again don't just magically dissapear when a bunch of people stick to party lines.

Alas, we are in an age of hyper over-regulation though and this is just another example. I could come up with countless others in wildly different fields which have one astonishing commonality. That business has been running fine for ages and all of a sudden, we need to regulate.

We don't know whether or not we'll have stackless coroutines; it's possible that we hit design problems we didn't foresee. However, at this moment, the general consensus is that we are interested in pursuing stackless coroutines.

While Andrew has the final say, as Loris points out, we always work to reach a consensus internally. The article lists this an an implementation that will probably exist, because we agree that it probably will; nobody is promising it, because we also agree that it isn't guaranteed.

Also, bear in mind that even if stackless coroutines don't make it into Zig, you can always use a single-threaded blocking implementation of `Io`, so you need not be negatively affected by any potential downsides to fibers either way.

This new `Io` approach has made it strictly more likely than it previously was that stackless coroutines become a part of Zig's final design.

How so? Why would I not default filter e.g. Iran or Chad or El Salvador or most of the world on my home network? I can always unblock a specific IP if needed, but chances are that will never happen.

My kids aren't old enough for computers yet, but I'm mostly of the mindset that a whitelist or curated offline cache (at least for anything on the web) is the sanest approach for younger kids. Outside of .gov, .edu, a handful of discussion forums, and stuff not relevant to them like shopping/banking, there's honestly not a lot of utility to the web. If they end up interested in programming, reference material can be kept offline, libraries downloaded through a proxy repository, etc.

Really a great piece of work. At the opposite of the usual studies posted here.

With the headline we can easily guess that the study should be flawed, with the sample not representative, or developers not expert enough with the AI or so, and then, they give a very well done list of all valable objections with arguments about why they don't think that contradict the study.

That replied to all the questions I could have had in the end.

I tried to use Orion as my daily driver on Mac OS (instead of Firefox) but I couldn't get the simplelogin extension to work (it wouldn't authenticate to my account). Also, it was slower than FF (I know, everything says that it is super fast, but that wasn't my experience).

After a month or so, I gave up and switched back to FF.

I think the trouble is that certain adblocking features (like skipping ads on YouTube, Twitch, etc) require modifying the page you're viewing in your browser; just filtering network requests isn't enough. So right now a browser extension is the most natural choice for an adblocker, but honestly that might change if browsers keep being so hostile towards them.

I don't "bypass" Chrome when they want to melt my brain with their business model, I use Firefox. I don't "bypass" Windows when they want to melt my brain with their business model, I use Linux. No idea why so many "hackers" doing "bypasses" can't instead take action that is simpler, long lasting, and easier. Do people need to jerked around 50 times for 20 years before realizing it will keep happening and their "bypasses" are just temporary bandaids?

Cf also allows adding authentication. Everything from OTP to third party OIDC. Including major providers like google , github etc. In edition blocking access by region or country.

Also not everyone can simply open a port on their router. Lot of people have ISPs that prohibit that or are behind CGNAT. So CF tunnels makes it lot easier for them to selfhost and expose those apps.

> Corruption is not always the simple graft of the CEO and board. Corruption also comes in the form of a system where too many people make too much profit to want to make the system better.

maybe i misinterpret, but are you saying but it seems your saying some profit from govt spending is ok, but too much crosses a threshold to corruption?

if thats the case, how do we set that threshold? whats the criteria?

(i don't disagree per se, just curious on the thinking around this)

I think people are putting far too much of an ideological lens on this ruling. As a "matter of law" this seems like the right decision. The supreme court is not a board of dictators making societal decisions based on their flavor of the day. Their job is too see if the ruling is consistent with all other laws we have and the normal function of a modern society. Pushing the envelope one way or another is not their job even if they end up doing that. At the end of the day the (elected) state governments have decided to create a policy that reflects what their constituents want. The supreme court job is not to question the logic of that. They did not run for office or win elections. They just need to make sure that what being done is reasonable and not violating any existing laws. As a tech guy I think these laws are stupid but this case was not the right hill to die on. What needs to happen is that these laws get enacted, costs and unintended consequences happen and THOSE parties sue on the supreme court on that basis

> io.async expresses asynchronicity (the possibility for operations to happen out of order and still be correct) and it does not request concurrency, which in this case is necessary for the code to work correctly.

This is the key point for me. Regardless of whether you’re under an async event loop, you can specify that the order of your io calls does not imply sequencing. Brilliant. Separate what async means from what the io calls do.

These satellites are in a rather thin band of space and it's clearly a problem as debris has already hit the space station and satellites. Tracking satellites is clearly a necessity. Could we use some partners? Probably worth look into with the ESA and Japan/India to share cost, burden, and information. Not doing it because of a trite expression doesn't seem like a good idea.

Aren't most licenses "not fully understood" in any reasonable legal sense? To my knowledge only the Artistic License and the GPL have seen the inside of a court room. And yet to this day nobody really knows how the GPL works with languages that don't follow C's model of a compile and a link step. And the boundaries of what's a derivative work in the GPL are still mostly set by convention, not a legal framework.

What makes us comfortable with the "traditional open source licenses" is that people have been using them for decades and nothing bad has happened. But that's mostly because breaking an open source license is rarely litigated against, not because we have some special knowledge of what those licenses mean and how to abide by that

What would you use in its place? I've never had an issue with it. I use it for 1) early termination 2) carrying custom request metadata.

I don't really think it is fully the coloring problem because you can easily call non-context functions from context functions (but not other way around, so one way coloring issue), but you need to be aware the cancellation chain of course stops then.

I have the opposite experience with a router. I use mine when I need to, but I find using the correct hand tool far easier to control. If I had to do what you were describing I’d chisel the vertical cuts with a hand chisel so I had nice clean edges and I would hog out the material with a router plane. This one is my favorite: https://www.lie-nielsen.com/products/1-71-ct-large-router-pl...

The moulding plane book I linked really opened my eyes to creating profiles. I’ve had to match multiple non standard profiles cut into different mouldings, window sashes, mutton bars, etc in the old house I live in, and that would be impossible without cutting a custom profile for a shaper. Seems like a huge waste of effort to cut a tool steel profile for a one off when I can just grab a couple hollows and rounds and make literally anything.

Check out the maker of HNT Gordon using his planes. https://youtu.be/fHsEjiXv0c4?si=jyXdUilNnCtH7Xci

He actually has a different technique than the one in the moulding plane book I linked, and I like the book technique a lot more. It’s foolproof

Classic MBA scam. Hertz dont own the cars outright, they borrow money to pay for them. So they have an interest in driving down the value of the cars so they can refinance at lower costs. Then, on the income side, they'll be gouging customers for fees to cover damage (or take out curiously expensive damage insurance). It's a continual shakedown and I imagine there were high fives all around when the Finance intern came up with the idea.

Of course, Hertz has been a dumpster fire of a business for the last five years. Burning billions on electric vehicles, torching the share price, switching CEOs, not to mention falsely accsuing customers of theft. Maybe best to stay away from them for a bit.

It depends on how you interpret the word "properly". There are ads and adblocker-detection techniques that can't be blocked by MV3-style static filtering.

If "properly" means "can block all ads" then you're wrong. If it means "can block some ads" then you're right. If it means "can block most ads" then you're currently right, but likely to become wrong as adtech evolves around the new state of play.

Don't forget Chrome launched with built-in popup blocking. Now we just have popunders, in-page popups, back-button hijacking etc. Ads, uh... find a way.

This is being framed all dystopian, but I'm not so pessimistic.

The current process is ridiculous - a random teenager in a vest with 15 minutes of training inspects the car when you check it out, and then you get a former drill sergeant when you check it back in. The current process is no less fair and Hertz is no less evil - but in this case its at least impartial and the scans are transparently available.

The switch must be lifted and turned. The optional posts block you from inadvertently knocking the switch (that you must pull up and turn).

I second that it’s not an accidental motion, you must actively manipulate the switch. But just like your turn signal in your car, it is muscle memory when you use it. I just wonder what action the pilot mistook the fuel cutoff for. Looking around the cockpit shows just how unique those switches are and not something you mistake with another common activity.

Pretty sad day if this was an intentional action

I recall back in the day when I was an embedded systems programmer at the coal face I had similar antipathy towards a pattern. I think it was called the State pattern or similar. It involved a class hierarchy and virtual functions, one for basically every state, event pair.

I preferred my simple C design whic used a lookup table to quickly access a structure for each state, event pair instead. The structure would provide an output state, a message to send, an action to emit, a bitmask to select zero or more other standard operations, and yes a function to run in those rare cases where something really special was needed. All fields optional.

The point is I didn't need to write N x M functions, I just needed to edit a table. And I didn't need to understand any rocket science.

The report can be found here: https://aaib.gov.in/What's%20New%20Assets/Preliminary%20Repo...

> did the report say a one second delay or that the two switches were turned off at consecutive seconds?

The report states, on page 14: The aircraft achieved the maximum recorded airspeed of 180 Knots IAS at about 08:08:42 UTC and immediately thereafter, the Engine 1 and Engine 2 fuel cutoff switches transitioned from RUN to CUTOFF position one after another with a time gap of 01 sec.

"with a time gap of 01 sec" seems fairly clear. The final report will have more granularity, but I don't think that's very ambiguous.

You are still free to run the program as you wish, you just have to provide attribution to the end user. It's essentially CC BY but even more permissive, because the attribution only kicks in once when specific, relatively uncommon conditions are met.

I think basically everybody considers CC BY to be open source, so a strictly more permissive license should be too, I think.

I think Trump is dangerous because he's a particularly explosive combination of Evil and Stupid.

Evil alone (i.e. intelligent evil) isn't as dangerous most of the time, because usually it's manifested as ultra-egotism -- usually if they're smart enough they don't come to government at all. Because, as Trump saw, that's just asking to get shot in the face; although sometimes e.g. in the form of racism taken as a life goal, there's more power-seeking, but then intelligence excludes most stupid forms of racism as simply demonstrably false, and it's very difficult to run on blatantly evil missions like that, post-Hitler.

Stupid alone obviously is useless: they usually don't even achieve power, and if by sheer luck they do, assuming they're not evil, they just fumble around and ask for assistance without too much damage, and might end up resigning or being effectively sidelined.

Now Trump isn't 100% stupid, or 100% evil. He's a very dangerous combination: he probably really doesn't believe in climate change due to very seriously stupid propaganda (in turn produced and stimulated by evil parties) from the far-right/inforwars/whatever, which is pretty stupid. You can even disagree climate change is harmful for yourself (some scientists even did -- at least a few decades ago), but denying it just reflects not having studied the matter at all or listened to anyone that understands a tiny bit of the science. And he is evil in the sense that he might think that, even if this were true, the US stands to profit from oil (again, evil and stupid!). He is evil in his reckless commitment to rile up hate speech, while not seeing the policies he is pursuing are incredibly stupid, and just self-destructive.

The end result is I expect this to be a huge enormous mess for the US, but also for the world. We live in the same planet, and unlike some who like to cheer on their perceived enemies' demise, everyone will be affected if the US (and for example the science they support) destroys so much value. Just like Russia and others, they hold massive nuclear arsenals. I shudder at those who cheer for US's total demise.

The hopeful thing is that insanity inevitably shows how great sanity is. Evil tends to self-destruct. Just do what you can, and brace for impact. Then rebuild from the wreckage. Never lose hope in human potential for good stuff. Good night and good luck.

> Boston Metal uses electricity in a process called molten oxide electrolysis (MOE). Iron ore gets loaded into a reactor, mixed with other ingredients, and then electricity is run through it, heating the mixture to around 1,600 °C (2,900 °F) and driving the reactions needed to make iron. That iron can then be turned into steel.

Big picture - it's like smelting Aluminum, but with Fe instead of Al.* And about 600 °C (1,000 °F) hotter.

On the plus side, Fe is not nearly as fond of oxygen as Al is - greatly reducing the electrical energy needed to reduce the ore to metal.

> The next step is to build an even bigger system, Rauwerdink says—something that won’t fit in the Boston facility. While a reactor of the current size can make a ton or two of material in about a month, the truly industrial-scale equipment will make that amount of metal in about a day. That demonstration plant should come online in late 2026 and begin operation in 2027, he says. Ultimately, the company hopes to license its technology to steelmakers.

From a quick search, it looks like steel is worth ~$500/ton. So calling a 1-2 ton/day system "truly industrial-scale" might be correct language among metallurgical researchers...but it's probably orders of magnitude smaller than you'd need for an economically viable facility.

Maybe start with trying to manufacture some very expensive, low-volume specialty steels?

*EDIT: The usual https://en.wikipedia.org/wiki/Hall-H%C3%A9roult_process , for smelting aluminum, does emit a fair amount of CO2 - because [messy details]. The article basically says nothing about the actual process they're using for iron, ruling out a close comparison.

> unless it’s like, the news

Yes, but that’s part of the point: in the most formal registers, “America” is incorrect-if you’re a lawyer drafting a legal contract, or an academic writing an article for a peer-reviewed journal on international relations, you’d be much more likely to write “the United States” (or “the US” for short) than “America”-and if despite that you wrote the second rather than the first, it is likely someone else would “correct” it in the editorial process

So there is a very real sense in which “the United States” is more formally correct than “America”. But it is of course context-dependent: using the most formally correct term is likely pragmatically incorrect if your audience is a classroom of average seven year olds

Also, formality of speech isn’t just determined by context (a legal contract or a peer-reviewed article versus speaking to a primary school class)-it is also determined by the background of the speaker (and audience)-people who come from more educated/professional/higher SES backgrounds tend to speak more formally even when speaking informally; the same is true of higher IQ people and higher AQ people (AQ=autism quotient, measuring autistic traits)

I think it doesn't make any difference. Back in Russia, I used 2700K or 3000K LEDs. Here in the Philippines, high-CRI warm-color LEDs are unobtainable, and the culture exhibits a nearly-universal shift to 6500K indoor lights (unlike in Europe), so I use 6500K, just like everyone else here. It still works.
