Don't worry, it also hits birthday cards from my cousins, Christmas presents from my siblings, care packages with those favorite candies and coffees that aren't sold in the US. My sibling can't send me hand-knit items or hand-me-down kids items, items truly of de minimis monetary value.

It may be accomplishing what was intended -- but I don't think that people in the US (even those paying attention) understand what was intended. The lack of clarity in terms of regulations and collection of fees/tariffs show that it is not about efficiently collecting the $ but instead about breaking the chain of goods, from big business to small business to family ties, and cutting off flow to the USPS, supporting the privatization of the entity.

I agree that the de minimis exemption was being abused at scale.

I'm also salty that my family can't send birthday or Christmas presents, even a home-made card.

Whatever you want to say about this administration, always look one level down for the wholesale reconfiguration of supply chain and international connections that they're aiming for.

This looks great. I invest over an hour a day on Anki, so I'm probably your target audience.

I'd love to try Phrasing, but there is no way that I'm going to give my credit card information if I've never seen how it works. I'm not asking for special treatment. I think the 4 Euro 14 day trial should be free. Not because I don't want to pay, but because I don't want my credit card details shared with every service I ever try.

Yes, I understand that your credit card provider is safe and that is not my worry. It's just that handing over that information is a very large hurdle, and one that users get over only after you built trust with them. If we can never see what we're getting, we have no reason to get over that hurdle and develop that trust.

I'm much more interested in actively filtering it than cutting it. Think yahoo pipes except DIY and more sophisticated. That'll take time to build though.

In the near term I've found that asking an LLM with search/deep research to summarize news helps. Obviously zero shielding from bias, but at least its concise & all in one place

There is also kagi and newsminimalist for out of the box semi-filtered:

And if you believe nothing ChatGPT says then you simply suffer from the opposite bias. The dilemma is that it is mostly right, most of the time, isn't it? Almost like... people? I mean, one person responded with an error that ChatGPT almost certainly wouldn't have made: https://news.ycombinator.com/item?id=45158430

If ChatGPT says things that are empirically provable, then it's not wrong, is it?
Cecil B. DeMille and the Google Android Gmail App
by chrisjj | 2025-09-07 14:24:15+00:00
Cecil B. DeMille once filmed a pretty important battle scene ... or tried to. At completion he called to the cameraman “Did you get all that?”. The cameraman waved and shouted back, “Ready when you are, C.B.!

This was clearly the inspiration for the Google designers of the Android Gmail app. I click Send on an /important/ /time-critical/ message that would have gone immediately on the old Gmail web site, and the app dutifully closes... with not a hint of warning. When one hour later the recipient tells me /the message was not received/, I open the Gmail app... which pops up "Sending...".

The difference is of course that Cecil had three backup cameramen, whereas I trusted Google's /flagship mail app/ so didn't send the same message via three other Google products too... /i /i

Good **ing grief. It is not rocket science.

> The implication seems to be that the workers didn't have authorization to work there.

No one ever does, by that standard. In the US, if you're a professional coming in to do some short-term thing, there's no visa process. You just fly in and get the stamp in your passport, which is technically treated as a "waiver of visa". Then you do your job and go home.

Like, have you every flown somewhere to attend a conference and a meeting? Same thing. Where's the "authorization"?

Optional::map returns an empty optional if the passed function returns null. This is incorrect and can be especially hurtful in intermediate operations. Allowing Optional::map to return an Optional<void> would have been correct.

Alternatively, just don't call it 'map'.

I agree implementing your Option<T> type is better. The problem is that people will use whatever is available in the standard library—I am not working in isolation.

Berlin also invested billions into rebuilding much of its metro system in the 1990s and early 2000s. Now, 25y later, with investment having dropped off, it's occasionally creaking.

That said, to "beat BART" isn't a milestone for any public transport system anywhere. Except ... in the US, where even BART stands out as great. Hmm. Relatively.

(one part of me is kinda curious how the 101 would look like if you didn't do any work on it for 20 years. Mostly because it'd probably be a rather cool setting for some dystopian movie. Anyway ... transport infrastructure, whether public transport or roads, costs a f*ckton of money)

> We've already seen some huge, positive structural changes to our economy

None of this is good for working Canadians right now. The shit is about to hit the proverbial fan in this country in the next few months. And as bad as things might get in the US they're likely to be worse here.

Maybe in the long run we'll be on a stronger footing but it could also just lead to even more entrenched monopolies in the Canadian economy, and a victimized Canadian consumer.

I never claimed conclusivity; words like "apparently" were supposed to suggest that, which is why I didn't use "obviously," "definitely" or "conclusively".

Also, maybe be less of an asshole next time. People are allowed to be wrong, that is the whole point of a discussion, and ridicule is not a counterargument.

> The one detail I can't seem to find anywhere was what type of visa these SK nationals used to enter the US, and if they overstayed.

Because there is no visa process for short term professional work in the US, and never has been.

> A lot of countries are very careful to avoid letting you in on a tourist visa if you give off the appearance of entering to work.

That's just wrong. Virtually the entirety of the professional world travels around between industrial countries on tourist visas. Otherwise anyone going to a trade show is an "illegal" at risk of deportation.

I am homeless, I live in a minivan, and I have a solar battery charger with a small carbon filter/HEPA air filter that I use every night and it helps me so much. I am a very "sensitive" person to many things in the environment, but many times while traveling i find myself in the midst of wildfire smoke. (I also carry a facemask respirator for the same reason).

>Like, have you every flown somewhere to attend a conference and a meeting? Same thing. Where's the "authorization"?

Something tells me that working at a factory, even for "training" purposes is very different than attending a conference. Wikipedia confirms this:

>There are restrictions on the type of employment-related activities allowed. Meetings and conferences in relation to the travelers' profession, line of business or employer in their home country are generally acceptable, but most forms of "gainful employment" are not. There are however poorly-classifiable exceptions such as persons performing professional services in the United States for a non-U.S. employer, and persons installing, servicing and repairing commercial or industrial equipment or machinery pursuant to a contract of sale.[26] Performers (such as actors and musicians) who plan on performing live or taping scenes for productions in their country of origin, as well as athletes participating in an athletic event, are likewise not allowed to use the VWP for their respective engagements and are instead required to have an O or P visa prior to arrival. Foreign media representatives and journalists on assignment are required to have a nonimmigrant media (I) visa.[27]

With all due respect, I don't think you understand. The 128 bits are just to sort the 52 cards into a random-enough order, and they have sufficient entropy and space for that.

We're not interested in sorting all possible decks, just all possible cards (52) into 1 unique randomized deck. The more bits we assign to these, the more any error or bias in the source goes to nil. (In contrast, consider the use of only 4 bits.)

Since everyone's bashing my use of ChatGPT, I don't think ChatGPT5 would have made that categorical error.

I have tuned the news out as much as possible, as soon as I've realized it's mostly show biz.

The News, like any other media, is in the business of producing content and being watched/read/listened to, as much as possible. Not in the business of keeping me informed about what's going on in the world (that's relevant to me).

I don't want to bury my head in the sand. I do read/watch/listen to some of it. Usually weeklies, like The Economist, and I have a daily digest newsletter that dedupes and sends me local news from the day before. Between that and what I hear on the grapevine / from my friends, I trust that I am informed enough.

I was in the market for a new running watch recently, and was kinda disappointed no LTE options existed.

I'm very happy we're finally getting there, although pushing LTE down to the lower tier will take a while (I'm never going to buy a >1200$ smartwatch).

LTE support will kill battery life if online full day without doubt, but if Garmin plays it smart by limiting it to activity (with per-activity settings, e.g. a run may need an update every 3m, a trek maybe every 15m), sending periodic pings if out of BLE/Wifi range, and activating it only on user request for features, I could very happily live with 8 days of battery life (instead of 11) and LiveTrack support while I'm running, at least I don't need to carry >150g phone on my arm for 1h anymore.

I guess it would be a large and massive upswell in the coming decades because dementia isa trailing indicator and takes decades to have effect on populations. China only started pumping out massive amounts of dirty pollution in the mid 90's and China probably in the 2010s or so, so the impact is yet to hit them but if the conclusions are correct then wow...

> Solving the “what color is your function” problem.

Eh. I currently use monads for my effects, and am open to the idea of language-based effects.

But this isn't a solution to the colour problem - it is the colour problem. The compiler stops you accidentally calling red from blue. If you want to do it deliberately, you change the caller from blue to red.

Wow, this is a cartoon level villain. You're working too hard making us look bad! Didn't know there were people that actually thought like this.

Perversion of egalitarianism. Reduce everyone to the lowest common denominator as not to allow for any differences in people. Basically remove free will. Truly dystopian stuff.

The issue is, what else do you expect people to do?

They will destroy their own lives if all they worry about is the bigger stuff. There is no clear path from what an individual can practically do, to addressing those bigger things either.

For example, politically - anyone trying to do the actual effective thing in this situation is going to be thrown in jail, often with praise and finger wagging by the nominal folks in charge of those who it would be benefitting.

And since everyone would rather yell and scream back and forth at each other rather than actually do anything that matters, what else is going to happen?

That goes for pretty much every one of these hot button topics. People can only control what they can actually control, and at some point, those things are in bad enough shape that they require 100% of a persons attention. Or more.

This is 'California politics' by the way - and it's spread everywhere. Nothing is good, everything is bad, no one can do anything that actually benefits them, etc, etc.

Good question, but I will say yes just based on the science I know. The type of pollutant does not matter, it is whatever effects heat shock proteins to effect protein folding.

Heat shock proteins (and cold shock proteins) are affected by more than temperature, but temperature is really important as well.[1][2]

It seems to be multifactorial. Per an OpenEvidence query, which cites many recent studies:

"In summary, the mechanism of PM2.5-induced brain damage involves entry via the olfactory system and BBB, activation of glial cells, neuroinflammation, oxidative stress, BBB disruption, and downstream neurodegenerative changes."

In the 1920s poem, Desiderata, I was always surprised that Max makes a reference to career:

Keep interested in your own career, however humble;

it is a real possession in the changing fortunes of time.

Exercise caution in your business affairs;

for the world is full of trickery.

But let this not blind you to what virtue there is;

many persons strive for high ideals;

and everywhere life is full of heroism.

From Khrushchev's own words (27 October 1962) [1]:

> Your missiles are located in Britain, are located in Italy, and are aimed against us. Your missiles are located in Turkey.

> You are disturbed over Cuba. You say that this disturbs you because it is 90 miles by sea from the coast of the United States of America. But Turkey adjoins us; our sentries patrol back and forth and see each other. Do you consider, then, that you have the right to demand security for your own country and the removal of the weapons you call offensive, but do not accord the same right to us? You have placed destructive missile weapons, which you call offensive, in Turkey, literally next to us. How then can recognition of our equal military capacities be reconciled with such unequal relations between our great states? This is irreconcilable.

According to General Boris Surikov [2]:

> 'Khrushchev and his Defence Minister, Rodion Malinovsky, were at Khrushchev's estate on the Black Sea. They went for a walk and Malinovsky pointed in the direction of Turkey and said: 'That's where the American rockets are pointing at us. They need only 10 minutes to reach our cities, but our rockets need 25 minutes to reach America.' Khrushchev thought for a while and then said: 'Why don't we instal our rockets in Cuba and point them at the Americans? Then we'll need only 10 minutes, too.'

This article goes on to quote the Soviet Ambassador to Cuba, Alexander Alexeyev, who was a direct witness and a go-between between Khrushchev and Castro:

> 'On 14 May 1962 I was called to a meeting of the Defence Council at the Kremlin. Khrushchev said, in effect: 'Comrades, I think it would be a good idea to instal rockets in Cuba. Do it clandestinely. I don't want it known in the US until November (after the mid-term Congressional elections). Alexander Alexeyev, how will Fidel react when we present him with our decision?'

I personally think stopping the use of AI is silly. I mean you could apply this logic to everything that you would be using specialized tools for, to make life better.

Why would you use a car? studies show walking is better. Why would you use a calculator? studies show mental math sharpens your brain. Why would you type on a computer? studies show writing on a physical paper is better for you.

Fundamentally people tend to use AI to get a result and then just use it instead of critically thinking over it. It makes sense, we take the path of least resistance. Why care about how something works when it just works? This leads to cognitive decline.

Rather I propose that you use AI as one of the greatest search engines ever invented. Think of AI (LLMs) as a dataset of fixed knowledge that can talk back to you and actually help you find the information you want.

When I was looking into making selenium scripts, that I had to write for work, more robust, I came up with a solution to create an object for each page and use that object to navigate and interact with the page. I then had a conversation with gemini pro regarding this where it told me that, what I am trying to achieve is technically just Page Object Model (POM), a pre-existing concept in the world of test automation. This lead to a deep dive into the advantages/disadvantages and I then pitched it as a change to better write selenium code and it was accepted at work.

Likewise, you should not use AI to vomit you code but as a rubber duck that quacks back at you [0]

The real serverless horror isn't the occasional mistake that leads to a single huge bill, it's the monthly creep. It's so easy to spin up a resource and leave it running. It's just a few bucks, right?

I worked for a small venture-funded "cloud-first" company and our AWS bill was a sawtooth waveform. Every month the bill would creep up by a thousand bucks or so, until it hit $20k at which point the COO would notice and then it would be all hands on deck until we got the bill under $10k or so. Rinse and repeat but over a few years I'm sure we wasted more money than many of the examples on serverlesshorrors.com, just a few $k at a time instead of one lump.

I’ve reduced my news intake to broadly just AP News, with color commentary/opinion/perspectives coming from The Guardian and Al Jazeera as needed. For local news, it’s my NPR station (WBUR) and Universal Hub in RSS format.

The good news is I spend significantly less time doomscrolling (down, on average I’d say, over 90%). My anxiety levels are largely gone, and when they do spool up I’m equipped with the tools to interrupt or stop them.

The downside to this has been an increased reliance on my news intake by others who have abandoned it wholesale or only consume opinion pieces like the “nightly news”. It’s a markedly different kind of anxiety, because now I also have to be ready to teach these other people about things they really should be building habits for themselves - but if I bail out, they just rely on ChatGPT instead to explain complex topics while remaining bereft of nuance and historical contexts.

The current landscape sucks, because everyone is chasing bullshit KPIs (engagement metrics, attention economy, advertising revenue, etc) instead of just delivering high-quality journalism at rates the common man can’t afford to pass up (i.e., affordable). I do not blame people from noping out, but I remain angry that everyone basically abandoned RSS feeds and digestible news in lieu of clickbait, algorithms, and walled gardens.

That's true we don't know anything about markings that were made on organic materials.

We do know that art and other markings date tens of thousands of years before the first proto-writing. Writing is specifically about markings that form a language. So doodles and visual jokes (e.g. phalluses) wouldn't count. I don't know what you mean by notes, but writing notes without a language would be difficult I suspect.

But there could early languages that were written on organic materials. The main problem is there's a bootstrapping problem where you need to account for how the first one developed at all. After that you can continuously improve over time.

Not _really_. AWS has a budget tool, but it doesn’t natively support shutting down services. Of course, you can ingest the alerts it sends any way you want, including feeding them into pipelines that disable services. There’s plenty of blueprints you can copy for this. More seriously - and this is a legitimate technical limitation - of course AWS doesn’t check each S3 request or Lambda invocation against your budget, instead, it consolidates periodically via background reporting processes. That means there’s some lag, and you are responsible for any costs incurred that go over budget between such reporting runs.

Study: Household air pollution from solid fuel use as a dose-dependent risk factor for cognitive impairment in northern China

Link: https://www.nature.com/articles/s41598-022-10074-6

Conclusions (summarized by ChatGPT):

> People who use solid fuels (like wood, coal, or crop residue) for cooking or heating tend to do worse on cognitive tests compared to those who use clean fuels (like electricity or natural gas). This effect shows up across several areas of thinking, but the biggest impacts were on attention (for cooking) and orientation (for heating).

> The more often people currently use solid fuel stoves, the worse they do on attention-related tasks. For example: if someone cooks with a solid fuel stove 100 extra days in a year, their attention score drops by about 0.05 points (a small but measurable decline).

> Long-term exposure matters too. For every 5 extra years of solid fuel stove use (over the past 20 years), people scored about 0.07 points lower in attention tests. In other words: the longer you’ve been exposed, the worse your performance tends to be.
