Am I the only one here who is skeptical that the MRNA shots have a positive risk-reward tradeoff for healthy people?

My job is to rush out complicated things, and biology is much more complex than even hardware. I know how fallible experts are. I know what hysteria and pressure driven deadlines do to build quality. And I know that you can't really test long term effects of biological products without long term human trials.

I think everyone here knows these things too, but most have a tribal political reaction to trust these shots because you dislike the people questioning them.

> Induction motors can be used instead

Most of the automotive industry uses Electrically Excited Synchronous Motors (EESMs) as an alternative to NdFeB magnet motors not induction motors, but they have's taken off yet because investment in mass scale production only began 1-2 years ago.

This will change over the next 2-3 years because BMW, JLR/Tata, Mercedes-Benz, Nissan, and Renault Group have begun moving to EESMs. EU OEMs who have a major foothold in the EESM market like Valeo are lobbying 80% EU indigenization for automotive parts in the EU [0], and India is also started a fairly large industrial subsidy to mass produce EESM powertrains [1] and a number of the players like Sterling Gtake have gotten tech transfers from European vendors like AEM that started off as NatSec funded applications [2]. That said, I also haven't seen a same push for a domestic EESM supply chain in the US unlike the EU and India - GM vendor Niron Magnetics [2] is the only American manufacturer I know trying to manufacture EESMs domestically.

That said, for a number of brownfield military applications, the migration away from NdFeB magnets cannot occur without essentially rendering entire product lines inoperable and unrepairable. This is why NiB magnet chains are viewed as extremely critical.

> the road to becoming good

In my experience, it's totally not true.

Many college students of my generation are pretty good with LC hards these days purely due to FOMO-induced obsessive practice, which doesn't translate to a practical understanding of the job, (or any other parts of CS like OS/networks/languages/automata either).

I will give you an exercise, pick an LC hard problem and it's very likely an experienced engineer who has only done "real work" will not know the "trick" required to solve the problem. (Unless it's something common like BFS or backtracking).

I say this as someone with "knight" badge on leetcode, whatever that means, lest you think it's a sour grapes fallacy.

Going to the gym regularly is a strictly American thing. Americans are obsessed with gym culture in a way that other countries generally aren't.

Most exercise in Japan takes the form of constant walking. You can walk from most homes to stores and restaurants, from many homes to train stations, from many workplaces to train stations, etc. For many Americans, the most walking they do is the walk from the door to the car.

It's substantially easier to build up a lot of time exercising by just walking as part of the things you do in daily life; a dedicated workout is generally only about 45-90 minutes. And the people going to the gym in Japan are also participating in all that walking, generally.

Fun fact: in the 90's, the reference gauge for aircraft safety was 1 accidental fatality per 100 million hours of passenger flight. Which is amazingly safe, far better than car and on a par with train.

Now, facing the growth of air travel, it was decided to raise this bar to 1 per billion hour. Not as an end by itself - this comes at very high cost and had a significant impact on travel prices. But because, with the growth of air travel, this would have implied one major accident per fortnight on average. And because those accident are more spectacular and relayed by media, civil aviation authorities feared this might raise angst and deter the public from air travel.

So, safety was enhanced, but mostly for marketing reasons.

Anecdotal, but living in Japan now and I do eat much healthier and walk way more than I ever did. Sometimes it's just for fun since the city I live in is walkable, but also my commute to work involves at least an hour of walking to and from stations which I have gotten used to.

As others have mentioned, social pressure plays a role in fitness, but there definitely is an abundance of unhealthy food. A previous generation may have had less unhealthy food options, so I'd be interested to see if this trend continues. All the greasy fast food chains exist here too and they are always packed.

That is true. A lot of journalism and street photography is 35 mm and that was considered wide by then. The difference is that distortions were seen as an error back then. Wider angles were, as you said, not widely available but I think also not much desired. This changed in the 90s when some embraced the distorted look and made it part of our photographic vocabulary.

From the top of my head, for about 300 nuclear power plants around the globe, there have been 3 core meltdown accidents. It is a 1% catastrophic failure rate. It is quite bad!

Whatever the circumstances of these accidents, human nature and unexpected events allowed them to occur. Just like every accident, you can say after the fact they could have been avoided. However it is impossible to revert the consequences of a core meltdown at human time scale.

I am not anti-nuclear at all. But I certainly wonder what kind of organization is required to operate it safely.

> PHP community lacks the resources to see a non-PHP tool thrive.

Why do you think so?

The PHP Foundation has raised over 2 million USD in contribution and has over 500K in their balance currently according to:

https://opencollective.com/phpfoundation

PHP has some well funded groups using it like Wordpress, Wikipedia, Laravel to name a few.

And recently the PHP Foundation started officially sponsoring a Go project, FrankenPHP.

https://thephp.foundation/blog/2025/05/15/frankenphp/

So PHP looks like a friendly and well supported community to foster tooling made in other languages.

Solar has this problem to a much greater extent though. If you have a market where solar is >100% of demand during the day then it will be dispatching at or below $0/MWh for almost all of its life.

But of course the marginal market is not the whole story. In reality solar largely receives effectively fixed prices in most markets (via CfDs or PPAs). Nuclear does the same and can also take capacity payments and sell into flexibility markets where those exist.

> One could say the same of installing packages in most modern programming languages instead of writing the code from first principles.

I disagree, because libraries define an interface with (ideally) precise, reproducible semantics, that you make use of. They provide exactly what the grandparent is saying, namely a formal abstraction. When you have the choice between a library and an LLM, requiring equal effort, the library is clearly preferable.

When an LLM is more time-efficient at a given coding task, it can be taken as an indication of a lack of a suitable library, tooling, or other abstraction for the use case.

> all the Ohio sucks memes are part of a concerted effort to convince people it's terrible here and they shouldn't come.

This is completely true. Speaking of, I can connect you with a number of long-term Ohio residents who would be willing to execute a sale-leaseback agreement that expires when their youngest kid graduates high school. For a fee, since you’d be getting such a great deal and early access to prime real estate. I can even get you hundreds of acres of prime farmland, if your budget stretches that far. Let me know!

The photographer had to move quite a bit further back to get the subject to be the same size in the frame at 150mm as the subject was at 35mm.

They could have used the 35mm lens at the same distance as the 150mm lens and simply cropped and the perspective compression would be the same (it'd just be a lower resolution image).

And yet we've done it, and everyone around it likes it: https://en.wikipedia.org/wiki/ExPlace_Wind_Turbine#/media/Fi...

It's not particularly practical of course, because the real estate is expensive and the tall things in a city all fuck with the airflow... but then that's why this is a publicity stunt and not where we usually put them.

As a Japanese, I will also mention that what you see out to eat in Japan is not exactly what we eat at home traditionally. I doubt many would know about all the multitude of traditional dishes that my mom regularly made at home that one would typically not go out to eat, such as hijiki salad (ひじきの煮物) or kinpira gobo (きんぴらごぼう). These and others are the types of dishes that remind me of home (and not tamago-sandos and ramen). My mom emphasized eating things of different colors, which came in the form of assortments of various types of vegetables.

Also, portion sizes in America are huge.

When I was at DARPA, I worked for a spell on CALO, which eventually turned into Siri. The team that was doing the follow on to Siri eventually spun off of SRI as Quato (Kwato?). And I guess they liked me cause they wanted to interview me. During the interview, they pitched their service as "The Primer." Which was kind of funny since the Primer as described by Stephenson was as much a mechanical turk as it was a marvel of technology. I wound up working for Linden Lab instead, but really appreciated some of the people I met at SRI and Quato.

Also ... Hardly a day goes by that I don't think of the Feed / Seed distinction Stephenson talked about. When I look at the digital media ecosystem, it looks as if we're getting the worst aspects of the feed.

this is easily shown to not be true? from 2025 numbers I think:

You are again looking at yearly figures instead of instants. I already included data from 2021. It follows a similar trend in 2020, 2019 and earlier.

Here's a few examples:

https://energy-charts.info/charts/power/chart.htm?l=en&c=FR&...

https://energy-charts.info/charts/power/chart.htm?l=en&c=FR&...

https://energy-charts.info/charts/power/chart.htm?l=en&c=FR&...

https://energy-charts.info/charts/power/chart.htm?l=en&c=FR&...

Let me break it down for you:

Is a cold spell a yearly happening or an instant? It is an instant.

What does French neighbors do? They have large amounts of fossil capacity because they know they can't rely on French exports when a cold spell hits.

They need to both supply their own grid and supply France.

Who cares if France is exporting enormous amounts of electricity all around Europe during early autumn when temperatures are mild and no one cares?

When the grid is strained France relies on 35 GW of fossil based electricity production since the nuclear electricity is so incredible inflexible that it can't be utilized to match a grid load.

What would happen if you had two French grids next to each other both trying to export massive electricity when no one needed it while not being able to supply itself when a cold spell hits?

The majority of people I know who had homes built in the past 15 years are miserable or sold the houses after only a few years. Builder buries the homeowner in paperwork, contractual litigation, and passing them around subs, and ultimately they are left spending a fortune fixing glaring issues or finishing tons of incomplete work (I had a friend where they didn’t install an entire bathroom and then argued it was added late by the customer even though it’s on the blueprints for all the houses in the development).

Except, no, Starship is already hugely behind schedule when it comes to promises made for the Artemis program alone, and the design of Artemis has massive compromises to account for Starship (up to a dozen or more Starship launches for a single trip to the moon), which also requires SpaceX to come up with a solution for in-orbit refueling (which they don't yet have, and has never been demonstrated, and by all accounts SpaceX appears to be unreasonably optimistic about the shelf-life of rocket fuel in a hypothetical orbital depot, which is a huge risk to the feasibility of Artemis). In the meantime, Starship has limited independent economic prospects because the world just doesn't have the demand for that much launch capacity, and there's no reason to think that Starship will be more economical for the vast majority of launches (for the same reason that the vast majority of commercial airline flights are not on jumbo jets). SpaceX's mercurial leadership represents an existential risk to the entire company by working on the wrong things and making unrealistic promises that they have no clue how to fulfill, for the same reason that Tesla's mercurial leadership represents an existential risk to the entire company by working on the wrong things (cough, cybertruck, cough) and making unrealistic promises that they have no clue how to fulfill (cough, camera-only autonomous vehicles, cough).

This revolutionary alarm system combusts upon detecting flammable materials within close proximity. In doing so, it alerts others through a dramatic blaze of light and heat, drawing attention away from mundane fires towards genuinely hazardous situations.

I only started seriously looking for work again about a month ago. I'd like to stay in this area for a few reasons but I would relocate if necessary. I worked remotely from 2015 until a layoff in late 2023 and this was the first thing I came across after that. It was okay for awhile and actually pretty interesting at first but the hours aren't reliable and there doesn't seem to be much opportunity for getting promoted.

There probably will be, but they don't need transit to transform development because no one wants three years of competing with their neighbor for developer and contractor resources. 80% will rent or buy elsewhere. Some may return and purchase into a new Palisades development.

Probably worth noting that Rick Caruso, an LA developer and mayoral candidate, has one of the few developments ("Palisades Village") that was not burned due to it was designed with fire resistant exteriors, roofs and cladding.

I created a Nano Banana Prompt Generator. Instead of just browsing existing prompts, you can now generate fresh ones with a bit of guidance. The idea is to make it easier for people who are new to Nano Banana (or prompt writing in general) to get started.

For example, if you enter "3d figure" in the input box, a complete 3d figure image prompt will be generated.

Try it here: https://nanobananaprompt.org/prompt-generator

Well I went to the updated Guardian article that is the original source [1], and it now states:

This article was updated on 12 September 2025 to remove quotes after the verified source who attended high school with Tyler Robinson said after publication that they could not accurately remember details of their relationship.

That reads more like "there's too much room for doubt for us to be willing to publish it", and not at all like "known-untrue bullshit". But it's a nice argument we're having - any uncertainty debunks my position, even when nobody has even disputed my strongest evidence, the shell casing messages, while the position I'm arguing against is simply taken as true without any evidence.

Hey why don't we flip things around? Why don't you give a source for "didn't know him at all", as well as for the "retracted as bullshit" (specifically the as bullshit part, not just "source was unreliable"). And if you can't find a reliable source, we'll assume the opposite is true. That's how you're making me argue, so it's only fair the same rules apply, isn't it?

Now that is not to say that this story is false, or even that the business model is necessarily bad, I will leave that up to you to decide. But this media source has a different set of motivations than most readers are used to. You'll notice that the news is about two US companies that are easily shortable, DHI and LEN.

Germany could have decarbonized faster by maintaining its nuclear power, but only to a limited extent because the bulk of the coal (especially lignite, a high CO2 emitter) is burned to generate electricity in the former East German regions, which have been devoid of nuclear power since 1995 (Soviet reactors were shut down due to their unsafety). Therefore, all active reactors were located in West Germany, and there is no adequate high-voltage line capable of transporting their output to the East.

At its peak (in 1999), nuclear power produced only 31% of Germany's electricity, itself less than 25% of the energy consumed (even considering primary energy, it only provided 12.7%), and by 2011 (Fukushima...), it was producing less than 18% of the electricity.

Moreover, in the East, coal-fired power plants have long produced high-pressure steam for district heating (industry and heating many premises), which a remote reactor cannot provide.

To claim that Germany shut down its reactors for no reason (after Fukushima...) or that only a minority of environmentalists decided to do so is misleading as, in Germany, all political parties close reactors, and most reactors were not closed by "Greens".

Furthermore, this nuclear potential would result in higher costs and dependency since it would have replaced part of the huge coal industry, which is very difficult to get rid of.

My ideal coding configuration is 3-4x vertical 32" UHD screens (with the smallest bezels you can get) in a 'curved' formation.

I find that configuration miserable for any hobby activities. I really like a horizontal screen, and curved is nice, but one screen even the ultra wides just isn't enough for work.

Maybe I could imagine a pair of ultra wides in an over/under configuration, but I really like vertical real estate.

Exactly, it's easier than developing a CPU the normal way and offers the possibility of making something that has unique capabilities as opposed to the mostly boring option of revisiting the Z-80 [1] or the near certainty of getting bogged down trying to implement a modern high performance CPU and getting pipelining, superscalar and all that to work.

[1] with the caveat that extending that kind of chip to support a larger address space and simple memory protection is interesting to me
