> Also, what IDF is doing is not genocide.

A total aside here. I wonder for how much longer this kind of speech will be tolerated? I‘m sure jjaksic believes this and is not actively trying to be hateful (or at least I hope so), but when it comes to other genocides we don’t usually tolerate genocide denial, and correctly mark it as hate speech. I wonder what makes the Gaza genocide different?

One reason could be that the Gaza genocide is ongoing, and history has yet to judge it, but I doubt that. Denying an ongoing genocide is much much worse than denying past one. Another possible reason is that we give people slack because of the lax information environment. If so I hope we stop that. Victims of genocide deserve better, and we should not be considering the reason people say such hateful things.

imo this is what good parenting should be about regardless of one’s class or upbringing.

It’s good to show kids which possible “doors” they can go down in life. It’s easy to claim that door X is better than door Y, but unless you have them _see_ the difference, or at least talk to someone that’s been through door Y, they won’t believe you.

There’s nothing wrong with focusing on a difficult track! But if you grow up to be an adult that doesn’t comprehend how a normal person lives, then you’ve got a problem lol.

Galvanized rebar and epoxy coated rebar have been available for many decades.

They are so much more expensive than ordinary carbon steel rebar to be unicorn poop rare.

If there is a break in the finish, it is as susceptible to corrosion as carbon steel. This means every step requires special handling and rigorous inspection. It cannot be field fabricated with a hand bender if a stirrup is missing or damaged. Tying and placement has to be done with unusual care to avoid damage (and again non-standard level of inspection).

Galvanizing and epoxy coating are long lead time and require prefabrication (bending). So you are shipping, handling and receiving bespoke space filling shapes instead of commodity straight bars to specialty job shops with limited capacity and well booked dance cards.

At every step, everyone has to price their work against all that complexity, uncertainty and potential for delays.

I don’t want to burst your bubble but be careful how much money you decide to set on fire with Rork. In vibe coding, the solution is always 1 prompt away, it can feel like “one more and everything will slot into place”, unless you are actively coding and steering you will not be able to produce and iterate on an app with AI alone.

If your app is simple enough (1-10 prompts) you might be able to pull it off but only as an MVP (maybe that’s all you need), you won’t be able to actually launch, or rather you might launch but the app will collapse under its own weight after more prompt iterations.

And yes, if you want a good app, £100K with a full time senior dev seems completely reasonable (knowing nothing more about your app). That number doesn’t shock me. If your app is very simple then that’s high but that number is not out of them question for an app (and backend?).

The share that Japan has today is a fraction of what it was at 50 years ago, and South Korea's is a fraction of where it was 20 years ago. Both Japan and SK's shipbuilding capacity shifted to China by the 1990s and 2000s when their keiretsus and chaebols like Mitsui and Hyundai began investing in CN (and Singapore's Temasek and GIC co-invested in port management and logistics), but both began shifting rapidly away from China in the mid-2010s due to the Senkaku Diaoyu standoff and the THAAD standoff respectively.

For example, Japanese shipbuilding conglomerates like Mitsui and Kawasaki began a large partnership with the Philippines to ToT much of their technology and invest in building an alternative capacity in Subic 15ish years ago [0] which helped increase PH's share. HD Hyundai and Hanwa began a similar expansion in Subic over the past 3-4 years as well.

HD Hyundai and Hanwha began doing something similar in Vietnam in the past 5 years due to the FTA and VN's industrial incentives for shipbuilding [1] and India's recent PLI over the past year [2][3]. The UAE has been playing a major role on this front as well because DP World has been co-investing in shipbuilding and port capacity in Vietnam (Saigon), India (just about every container port), and SK (BJFEZ) - the largest ports in all 3 countries are either owned or managed by DP World. One of the best strategies I've used in my career is to follow where and what Abu Dhabi and Dubai affiliated SWFs and SOEs invest or partner in - they have become similar to what Temasek and GIC were 20-30 years ago.

It's always weird to me that acetaminophen has such a low therapeutic index, like in order to get enough for it to do anything, you're also on the verge of liver failure (especially if you also drink alcohol). Also it just doesn't work super well in my personal experience --- I hardly feel anything when I take it. And yet it's one of the most commonly taken medicines worldwide.

Yes, I think this is why mermaid is hard to beat right now. LLMs seem to understand the syntax well.

I’ve used AI to build mermaid diagrams during ongoing system design discussions from transcripts as they progress.

I’ve rendered them, shared them and then the group can look at them and iterate very quickly.

A bunch of the rendering tools aren’t great, but some are and decent basic styling makes a big difference.

Ive designed bathroom fixtures before Apple and had been parked at Apple making the dumbest looking computers you can image for a very long time until my Dad's lifelong coworker brought Steve back --something I am on record telling people would be the only thing that would save Apple's arse (usually adding that Hell would freeze over before that happened). When Steve returned, he found all they had left was an ability to make laptops and so, the race was on to surround them with fixtures..enter his old pal Jony Ive. In the time since, things got a bit out of hand (pun intended) with the Vision Pro, he's moved on and Tim Apple figured out a way to get all the R&D money back...but

did Ive just land $6B+ for incarnating "Dr. Theopolis"?

Yes, https://youtu.be/1ZCxXjDlaf8 yes, I think he did... Good on Him! :D

> Allium adds a thin protective layer of stainless steel on top of traditional steel rebar to make it more resistant to corrosion

So it's like galvanizing but with stainless steel. Thing is, stainless steel still rusts; just how much depends on a number of factors. And if you slightly nick the stainless coating to expose the iron rebar, now the whole rebar rusts.

Maybe it will reduce the amount of corrosion, and that's great. But I highly doubt it would double the life of bridges.

I suggest a similar experiment and let some English professors explain the meeting of some contemporary rap songs. I guess they would struggle as well (depending on which song one chooses). Now the professors likely would argue that the rap songs are not relevant, which tells me they (as English professors) are simply not interested how their language evolves.

All that to say it's difficult to read and understand texts that are from a culture you're not familiar with. And I would argue that one can be perfectly fine as an English major in the US not being familiar with Dickens.

> I don't want to be a conspiracy nut, but I have to wonder how many separatist and protest movements are unknowingly getting external support to produce geopolitical disorder.

I'm Latin-American, so this doesn't sound at all nutty to me. The USA has long been doing this: from successful attempts promoting separatism in Panama and Texas, to failed attempt in Sonora and Baja California (officially a private citizen acting in his own accord, but conveniently enjoying the complacency of the US Government). It's one of the strategies big powers use, and there's more examples of this in Europe, Asia, and the rest of the world.

I think it's worth considering that perhaps this isn't Russian-fueled separatism, but American-fueled. The would gain a lot USA from an independent Alberta. It'd go the way of Texas— independent for about a year and then incorporated into the United States. Moreover, Alberta statehood would create a geographical rift in Canada that would place immense pressure on British Columbia to go independent or join the United States too.

It would also make the future annexation of the Northwest Territories and the Yukon much more likely, which would not only give the USA better access to the North-West Passage [1] and a wealth of resources, but it would connect Alaska to the rest of the continental USA.

> From my observations, having low parental involvement and excessively unstructured upbringing doesn't automatically produce determined and self-directed adults.

Sample of one, it indeed didn't. However being knocked around did help with being somewhat more ready and open to new things and uncharted territories. It also dramatically reduces the fear of the unknown and can be a significant confidence booster.

> Conservatives are the defacto minorities in a modern western country.

Conservatives are a minority in the U.S., but conservative-to-moderate populists are a majority. According to Vox, Trump would have won by almost 5 points if everyone had voted: https://www.vox.com/politics/403364/tik-tok-young-voters-202.... And don’t forget that the populist faction of the Democratic Party doesn’t exactly love Harvard either, as the beating heart of borderless neoliberal elitism. A large chunk of the party is in it for the Obamacare.

Heck, the Democratic Party as it exists today would not be viable at the national level without first or second generation immigrants. It’s reliant on the people who have the shallowest roots in and least understanding of america, who can be most easily be manipulated through ethnic machine politics.

After the U.S. nearly banned immigration in the 1920s, the foreign born population slowly shrank, reaching a low of under 5% by 1970. Italians and Irish lost much of their separate ethnic identity and began voting as individuals free. Between 1972-1992, Republicans then won 4 presidential elections by landslides over 5 cycles. That’s what happens when the electorate comprises mostly assimilated americans.

Yes, I guess this is what self-taught looks like. Although I have seen the use of mnemonics to remember the order of things in many contexts in music, including formal teaching. I thought some of these were universal: FACE and Every Good Boy Deserves Fudge for the note names on the staff, Father Charles Goes Down And Ends Battle, Battle Ends And Down Goes Charles' Father.

By this time I must admit that the random note playing is just an activity that I enjoy improving at independently, while I do think it's also making it easier for me to pick up new pieces quickly.

> "So far, we have (at least): RSA keys, SHA256 digests, RSA signing, base64 but not really base64, string concatenation, JSON inside JSON, Location headers used as identities instead of a target with a 301 response, HEAD requests to get a single value buried as a header, making one request (nonce) to make ANY OTHER request, and there's more to come.

We haven't even scratched the surface of creating an order, dealing with authorizations and challenges, the whole "key thumbprint" thing, what actually goes into those TXT records, and all of that other fun stuff."

I flagged this article and later saw it dead, so I’m quite surprised it came back. I found the content extremely shallow and lacking nuance. Others have mentioned, but it leaves out huge caveats because it would destroy the the conclusion - the cost of moving to the place in the first place, social connections, health (even worse for those with disabilities), emergency services, retirement, etc etc. The list of obvious hurdles that immediately disqualify most people is a glaring omission and I really don’t understand why this article garnered upvotes aside from affirming confirmation bias. This is the first time I’ve been greatly soured by the response from the HN community. What substance are people finding in this article?

Of course you are right, not everyone has the option to move back in either their parents, and of course that option (when available) is often not rent free (nor should it be.)

However I don't think that's what the parent poster meant. I think he meant "home" is the "home town" sense.

There's a perception that young people (for probably 60 years now) see "getting out of this town" as a major life goal. Small towns find it hard to hold on to folk in their 20s as they head off into the world seeking the excitement of a bigger city, industry location, or indeed just the option of choosing from a list of more than 2 places to eat.

The parent poster is suggesting that after experiencing that, and discovering the negatives (high housing cost being one), if you have a job which can be done remotely, then Starlink allows you to do that from your home town.

Of course this is a viable option for some, and likely not for most.

I read somewhere that designing a new plane would be a financially challenging proposition, with a comparatively small return far down the road.

Plus, it would be a new type and airlines would end up with hybrid fleets, increasing logistics costs (spare parts stocks, retraining of mechanics, pilots who couldn't readily switch between new and old planes and probably more).

In short, not a compelling proposition for anyone involved.

This is correct imo.

...and just like no one is prepared to pay 500 different vendors for micro-transactions, no one is prepared to pay 500 different websites for their MCP services.

Much much more likely is that a few big players (like google and AWS) will have paid-tier 'mega-MCP' servers, that offer 90% of what people need and fit in with existing payment/auth solutions (like your AWS account) and...

...everyone else with an MCP server will be left out in the cold.

That's what's going to happen.

These MCP servers will be cute for a very very short amount of time until people try to monetize them, and then they will consolidate very very quickly into a much smaller set of servers that people are already paying. Mostly cloud providers.

If I read this correctly they plead guilty at the end of bidens presidency but the plea deal was rejected by a judge.

Reasoning being the the DOJ was being accused of potentially making a choice for a person to monitor the pea deal terms based on DEI instead of competency.

Adminstaration changed, and with the DOJ of the current administration in place they instead got out of it with a settlement instead of a felony?

There is a few things here.

One, most people would really mean "not worse than average" when they say "better than average": we mostly don't want to be the very bad ones.

Then, like with Murphy's law, we mostly notice the bad, and compare ourselves to the worst we've seen: any every one of us is sometimes a bad driver, sometimes a bad teacher, or does stupid non-intelligent things.

Next, people usually compare themselves to the "union" of all the instances of bad events of everybody else: it's obviously more likely that there are more "bad" things thousands of people around us (eg. in traffic) do compared to our single self which we "observe" 24/7.

Finally, we are more lenient with ourselves and won't make much of a fuss when we sometimes mess up because we'll know we don't do that very often: so "average" number of bad events would seem lower than it is for ourselves. But 4 times in 100k is much lower than 12 times in 100k (eg. imagine you've been in 4 minor traffic accidents in 100k drives over your lifetime, but really, only someone else has saved your ass another 8 times or you'd be in 200% or 3x more).

Instead of just assuming I am below or above average, I assume everyone else is like me: as smart as me, as a good driver as me, as a good teacher as me...

But human behaviour is complex, and determining what "good" really is is very hard, so I think you can also look at it objectively and sometimes really claim you are better than average as long as you are aware there are things where you are worse than average (admitting those publicly is also another matter).

Maybe the ozone layer protects them? Your conclusion that nitrogen molecules in the atmosphere only survive a minute or so during the daytime isclearly wrong; if it were true, the atmosphere would be about 2% brown nitrogen dioxide like the output of a Birkeland–Eyde reactor a couple of minutes after the sun came up (or more, since the temperature and pressure are lower) and everyone would have died at sunrise today. Or, rather, biochemistry would look almost unimaginably different, having evolved to resist being oxidized by nitric acid.

UV breakdown doesn't appear as a significant source in http://nmsp.cals.cornell.edu/publications/factsheets/factshe... although lightning does. So, if this mechanism is operating at a significant scale in Earth's atmosphere, it's escaped the attention of the scientists who specialize in the terrestrial nitrogen cycle, which seems implausible.

> You can think of algebraic effects essentially as exceptions that you can resume.

How is this substantively different than using an ApplicativeError or MonadError[0] type class?

> You can “throw” an effect by calling the function, and the function you’re in must declare it can use that effect similar to checked exceptions ...

This would be the declared error type in one of the above type classes along with its `raiseError` method.

> And you can “catch” effects with a handle expression (think of these as try/catch expressions)

That is literally what these type classes provide, with a "handle expression" using `handleError` or `handleErrorWith` (depending on need).

> Algebraic effects1 (a.k.a. effect handlers) are a very useful up-and-coming feature that I personally think will see a huge surge in popularity in the programming languages of tomorrow.

Not only will "algebraic effects" have popularity "in the programming languages of tomorrow", they actually enjoy popularity in programming languages today.

go to ChatGPT and ask it to ask you relevant questions w.r.t. what blood tests you should order. then book them at Quest Diagnostics yourself for like $100 total. then ask it how to interpret the results.

voice any other concerns you might have as well.

follow up with human doctor only if necessary.

These charts are serving a few purposes. First of all, it is motivating to me to see improvement. I can see for instance learning curve dropout when I skip practice, and knowing what a gap will look like on the chart motivates me to keep going. I also use the key-specific curves to choose keys to focus on, so that I don't keep going on the ones I know well. I'm planning to add some more visualisation to understand if there is a pattern to perhaps sharps or flats being harder, or if there is a sharp to flat transition effect which I suspect at the moment - after playing a few days where all the keys are sharps, it feels weird to move to flats.

I have considered lessons but I didn't like the prospect of searching for a teacher. This particular piece of practice is only one part of my larger music-making activity. I make mostly electronic music using Ableton Live and a Push 2. I play guitar with enough proficiency that I don't feel like I need lessons. I started this sight reading excercise to access the sheet music I have and I'm using that just fine to learn pieces. So I guess I don't feel any particular frustration in my learning right now that would push me to ask for help. The main challenge I face in my music making is finding longer stretches of time to work on my songs.

In my first few years on the job, I would fill out peer evaluations honestly. We have peer evaluations where you rate people out of 5 on various performance elements like "innovative" and "leader" or whatever. Then I survived a couple of rounds of awful layoffs where really good people lost their livelihoods.

Since then, I put 5 out of 5 on everyone for everything always, and say something nice in all the boxes.

The claim is that it will reduce corrosion by 3x. If corrosion of rebar is the primary bottleneck to bridge longevity, a 3x longer life seems like a reasonable claim.

Of course in practice if this rebar is used in a bridge you might start to discover other things become the bottleneck, but that remains to be seen.
