johnyzee··on Amelia Earhart's Reckless Final Flights
WTF is with the "coördinated" umlaut... Seriously the New Yorker works hard to earn their monocled caricature.
johnyzee··on Coding without a laptop: Two weeks with AR glasses and Linux on Android
First thing I thought. If I go to a coffee shop or the park, it's because I want to enjoy that place, not do the same work I could do (better) at my desk. That's an aside, though, the OP's setup is really cool and intriguing.
johnyzee··on OpenAI releases image generation in the API
I wanted to try this in the image playground, but I was told I have to add a payment method. When adding this, I was told I would also have to pay a minimum of $5. Did this. Then when trying to generate an image, I was told I would have to do "verification" of my organization (?). OK, I chose 'personal'. I was then told I have to complete the verification though some third party partner of OpenAI, which included giving permission to process my biometric information. Yeah, I don't want to try this that bad, but now I already paid you and have to struggle to figure out how to get my money back. Horrible UX.
johnyzee··on Athena spacecraft declared dead after toppling over on moon
If they can control the angle of each leg with enough precision, that might be enough to compensate for (slightly) uneven terrain.

I understand that the recently successful Blue Ghost has sensors to detect suitability of the landing spot, and used it to re-position twice while landing. Starship would probably need something like that, too.

johnyzee··on Dozens of U.S. academics lose grants from Minerva Research Initiative
(1) I am wary that the Pentagon aims to make the world safer, at least in the sense of the word that most regular people share, (2) I particularly dislike the Pentagon meddling in secret social science undertakings to pursue those goals, (3) even if the Pentagon's efforts were benign, I believe there are better places and ways for those pursuits to be undertaken.
johnyzee··on Station of despair: What to do if you get stuck at end of Tokyo Chuo Rapid Line
If you're alluding to immigration, this cannot be blamed for vandalism and littering. Other kinds of crime, arguably, but not those, there are plenty of middle class shitheads who will happily do their part.
johnyzee··on Type 2 Diabetes and cardiovascular disease attributable to sugar beverages
>I do the same for fats. The way I look at it, I want to maximize the "enjoyment per kcalorie". :)

We are increasingly moving away from looking at fat as an indulgence, towards understanding it as an essential nutrient, with a large variance in fat types and their benefits. E.g. some people would avoid eating nuts, because they are high in fat, and not as tasty as something similarly fatty, like a pastry. This seems wrong both intuitively, but also from empirical findings about the impact of certain omega-3 fatty acids (such as in nuts) versus that of, say, omega-6 fats, which are way overrepresented in our diets due to being so cheap.

johnyzee··on Our muscles will atrophy as we climb the Kardashev Scale
They keep lowering the standards for acceptance into the military, because young people are becoming less and less fit.

johnyzee··on Scientists are learning why ultra-processed foods are bad
The refined sugar you buy in the store ('table sugar') is clarified with phosphoric acid and bleached using a number of other chemicals. In addition to this, it goes though a number of other industrial processing steps that you would not be able to perform at home. Hence, it is 'highly processed'.

johnyzee··on Scientists are learning why ultra-processed foods are bad
Refined sugar is extremely concentrated compared to the natural sources. You need like 50 kilos of sugar cane to produce one kilo of refined sugar, and through multiple steps of heavy industrial processes.

You could make a case for honey, but, like all other natural sources, it contains other ingredients that somehow limits ingestion or metabolization.

johnyzee··on Scientists are learning why ultra-processed foods are bad
You can process wheat into flour at home. You cannot process sugar cane into table sugar without an industrial plant.
johnyzee··on GLP-1 for Everything
Fasting increases growth hormone release (dramatically, in the case of extended fasting), which counters muscle loss. Does this happen with GLP-1?
johnyzee··on GitHub cuts AI deals with Google, Anthropic
> “The size of the Lego blocks that Copilot on AI can generate has grown [...] It certainly cannot write a whole GitHub or a whole Facebook, but the size of the building blocks will increase”

Um, that would make it less capable, not more... /thatguy

johnyzee··on What is the history of the use of "foo" and "bar" in source code examples? (2012)
There was a concept of treating women with respect.
johnyzee··on Reports of the death of dental cavities are greatly exaggerated
The tone of the article is for some reason very dismissive and derisive of alternatives to plain dental hygiene. As you point out, if a simple supplement in the form of harmless bacteria could improve caries reduction by even a small amount, it seems it would be a valuable option.

There is an existing 'probiotic' that has been around for years and works the same way, and promises the same benefits, as the one described in the article, it is called Streptococcus salivarius M18, there are quite a few studies that indicate it does work to some extent [1]. You get them in the form of lozenges that you put in the mouth while sleeping and they dissolve by themselves, so not a very invasive treatment if one wanted to use it.

johnyzee··on Show HN: Infinity – Realistic AI characters that can speak
It's incredibly good - bravo. Only thing missing for this to be immediately useful for content creation, is more variety in voices, or ideally somehow specifying a template sound clip to imitate.
johnyzee··on Telegram founder Pavel Durov arrested at French airport
It's largely second generation immigrants (yes, mostly from Africa and the Middle East, since that's where most immigration - in the shape of refugees - comes from).

And take it from someone who actually lives in the area (as opposed to HN speculators): YES it has gotten significantly worse over the last five years (having already been bad for decades), and YES 14 year old hitmen with explosives and automatic weapons are now an actual thing, not just a couple of incidents.

The politics of this is so inflamed, which makes it harder to discuss, much less solve the problems. I am not against immigration per se, from any given country. But right now, it is obviously causing major problems that need to be handled with extreme prejudice.

johnyzee··on Open source 'Eclipse Theia IDE' exits beta to challenge Visual Studio Code
I share your befuddlement. Eclipse is good and overall better than even paid proprietary IntelliJ. I think there is a lot of bandwagon jumping, especially with newish devs.
johnyzee··on How Alexa dropped the ball on being the top conversational system
If only there was a technology that understood unstructured natural language really well.
johnyzee··on Can ketones enhance cognitive function and protect brain networks?
That is the general experience, I think.

I did pretty strict keto for 2.5 years. Been off it for about a year now, while many of the habits stick (I eat next to zero added sugar, and generally low carb, less processed food, etc.).

I got rid of a lot of weight and some skin conditions. It was generally very positive. It was weird to have such stable blood sugar that you never feel hungry, even when not eating at all. There were some adverse results too, like zero muscle strength. I also digest carbs worse now it seems like. There might well be ways to avoid those issues with a more carefully managed keto diet.

I'm not sure if I will jump back on a strict keto regimen, it requires quite a bit of effort to plan meals, especially when other people in the household eat a regular diet. I have come to see keto as an intervention, very effective at fixing acute issues. Once you have done that reset, I think a lot of those wins can be maintained through generally healthy habits (which you now understand a lot better).

johnyzee··on The Space Quest II Master Disk Blunder
I love the change history comments. They show a high level of attention to detail and craftsmanship, at a time long before source control tools made this kind of thing obvious (and honestly, even after CVS/SVN/Git it still wasn't obvious to a lot of people).

This post also makes me think of the famous 'No Silver Bullet' essay[1], which in 1986 predicted that software would more or less continue to be written they way it was then, by programmers, painstakingly, one instruction after the other. The similarity of the game engine code (along with the comments) in the OP, to something I might have written today, bears this out, I think, almost 40 years (!) later.

johnyzee··on I can see AI genuinely amending or even curing the male loneliness epidemic soon
That seems obvious, but then I considered for a moment how many (in-person) relationships are based on lies, illusions, and misunderstandings about the other person - often not discovered until years into the relationship. With AI, at least you know that it isn't real. Which, maybe, somehow makes it more real...
johnyzee··on X confirms plans for NSFW Communities
> Elon Musk twitted about moderation being censorship

And instead, X has implemented hellbanning, where nobody outside X knows who is being censored and why. People just slowly figure out that, actually, no one sees their posts. At least with outright <scare-quote> "moderation" you would know that you had been cancelled.

johnyzee··on Parrots love playing tablet games. That's helping researchers understand them
Pretty good forward vision, better than I would have expected. Usuallly (non-predatory) birds turn their head to examine things. Maybe a curved screen would be one idea for better parrot UI.
johnyzee··on Java 22 Released
You can write write code outside of methods in a Java class, called an initializer block:

  class MyClass {
    {
      System.out.println("Hello World!");
    }
  }
This will run when an object of the class is instantiated. So not useful for the case in question (you could get rid of the class declaration but would presumably still need a main method).

(It's also pretty poor style, but occasionally useful in a pinch, like when instantiating an anonymous inner class, which has no constructors that take arguments)

johnyzee··on Starship's Third Flight Test [video]
Because that is their stated design goal for Starship.
johnyzee··on Starship's Third Flight Test [video]
Yeah, breaking up in-air during re-entry (at 65 km going by last telemetry) seems like a potential big issue to fix.
johnyzee··on Wear OS "Hybrid" design has two OSes, two CPUs, "100 hour" battery life
I will only use a watch that can viably replace a phone. That basically means a small smartphone, including LTE. With this package, I don't need my phone most of the time (leave it at home, or in a bag or coat). I can make payments, take calls and messages, and check my email. No need to carry a big hunk around in my pocket.

Current gen smartphones are basically there, with just a few improvements to UI and battery life. But even now, I don't mind charging every day. I just put the phone on the charger before going to bed, it's not a big deal.
