Just because it’s possible to outrun a diet it doesn’t mean it’s an accurate or helpful description of what most people are struggling with. If you look at the population of the United States as a whole, and the percentage of people who meet the criteria for obesity, it seems obvious that for the vast majority of people today, the problem is food, both quality and quantity.

As for your swipe at people in cities, I don’t know what to say - the fastest way to lower the amount of “diet outrunning” you and your kids do, is to move to a place where every daily activity requires a car and because everyone drives everywhere all the time, it’s not safe to let your kids roam.

I'm actually pretty excited about this, and I've always been surprised that there isn't an electric bike like this.

One of the main user interface challenges with a pedal assist E bike is how to make the experience feel as intuitive as just pedaling a normal bicycle with a chain, but be able to embrace all of the UX freedom afforded by the "Pedal by wire" separation.

Consider that because there's an electric generator that the pedals are powering, the software can vary how much amperage is allowed to be generated and so provide variable force feedback as it were, and the software can set any relationship between the input (pedaling frequency, torque, rate of change etc.) and the behavior of the traction motor. I think that's the basis for actually a very exciting pedaling platform.

They also say in the article that the generator itself can create enough power to substantively move the motor, which is pretty awesome in my mind but I can totally understand how that feels circuitous.

This is tricky to get right.

If the false positive rate is consistently 0.0%, that is a surefire sign that the detector is not effective enough to be useful.

If a false positive is libel, then any useful malware detector would occasionally do libel. Since libel carries enormous financial consequences, nobody would make a useful malware detector.

I am skeptical that changing the wording in the warning resolves the fundamental tension here. Suppose we tone it down: "This executable has traits similar to known malware." "This website might be operated by attackers."

Would companies affected by these labels be satisfied by this verbiage? How do we balance this against users' likelihood of ignoring the warning in the face of real malware?

I don’t really know who you’re talking to?

Your options are,

1. Buy Windows. Means you has absolutely no control.

2. Promote the development of anti-cheat on the linux, where you can not install it because you don’t like it.

No idea that you’re arguing against me, when all I’m doing is arguing for increased amount of freedom is tad silly.. no?

HTTP/3 replaces parts of OSI layer 4 (TCP/UDP). There's a perspective that HTTP has been trying to lower its layer for decades. Especially the way that TLS originated as HTTPS but now is almost a "universal" vertical chunk of Layers 4, 5, and 6. In that perspective HTTP is probably the new Layer 6.

Sure, but the responsibility for this dynamic is still on them. They've been buying into this abjectly brain dead narrative about the cause of the demographic slide - blaming immigration instead of the looting elites who have been turning the financial screws of wealth extraction, making it ever-harder to have kids.

As women entered the workforce, the definition of full time employment hours should have halved, right? And failing that, people's saved wealth should have gone up such that they had more negotiating power with their employers and working hours naturally went down. Instead the looters turned up the financial treadmill of low interest rates, dumping all the gains from having double the workforce, plus technological progress, plus offshoring into an asset bubble to benefit the wealthy. This is precisely why "the rent is too damn high".

But still rather than coming to terms with how they've been continuously enabling this by supporting fake "fiscal responsibility" Republicans (Democrats would have still printed most of that new money but at least spread it around a bit), they're leaning right back into that broken immigration narrative like a child's fucking security blanket - always getting stuck focusing on individuals who are different and turning to personal hate, while never even perceiving the system that has been deliberately set up to screw them over.

Yes, it allows them to solve their desperate need to combine spreadsheets, creating one big merged spreadsheet with pockets of corrupted data and fake last-names. It either lies undiscovered until clients complain, or I notice and have to redo the work for them properly, without an LLM. :p

> > History shows people are also very resilient at moving on from trauma

> i’m extremely skeptical that people move on

Historically, essentially everyone who lived long enough to have children had some of those children die [1]. So either:

- that wasn't traumatic

- they managed to deal with that trauma

- or they didn't move on, and everyone was somewhat traumatised

You can take your choice from the above, but on the whole this was the normal state of affairs for most of human history and prehistory.

How old is the kid?

When my kids were less than 10 I took them to the Computer History Museum in Mountain View CA and showed them how all the mechanical computers work. They have some exploded and simplified exhibits that are very visual so kids can get it pretty easy. Especially if they’re the kind of kid that builds with blocks. Games like Turing Tumble are good too. Then you just wave your hands and say chips work like this on the inside, but with electricity instead of gears because it’s faster, smaller, cheaper and uses less energy. But at the end of the day, it’s basically all clockwork. Then they smile and say, “makes sense”. And I leave it at that.

When the kids were teenagers I gave them a more thorough explanation.

If you’re not in the Bay Area then the Computer Museum does have YouTube videos. There are many others as well.

> ... then you've known someone who has struggled to eat enough to maintain and build weight.

I'm not trying to strawman here, but I've never met a person like that who was ever overweight at any point in their life.

It seems pretty obvious to me that saying "some people can't eat enough to put on weight / get fat" is a distinct thing from saying "someone who cannot stop putting on weight / getting fatter will almost never be able to lose the weight without adjusting their diet". Do you agree or am I missing something?

It's not even broken as the edge cases are addressed by ad-hoc solutions.

OP is complaining about global infrastructure not having a pristine design. At best it's a complain over a desirable trait. It's hardly a reason to pull the Jr developer card and mindlessly advocate for throwing everything out and starting over.

Despite reading the README and the article I am still unclear about how these templated values are populated. So presumably we store our HTML on the sql server along with some templating syntax then how do we plug that value so to speak?

Secondly, what do we do about things like HTML fragments à la HTMX / Datastar hypermedia approach? Do we just hit the DB for 10 lines of HTML to populate the next card in a multi step form?

People do skip words or scan for key phrases, but reading still happens in sequence. The brain depends on word order and syntax to make sense of text, so you cannot truly read it all at once. Skimming just means you sample parts of a linear structure, not that reading itself is non-linear. Eye-tracking studies confirm this sequential processing (check out the Rayner study in Psychological Bulletin if you are interested).

I read this article with a healthy amount of scepticism and read two separate stories:

1. This guy was targeted by spyware.

2. This guy was an iOS 0-day exploit developer and is involved with a bit of drama with his previous employer.

Everyone seems eager (including himself) on connecting the two, but why would the ex-employer go after him using illegal methods when they've agreed to a settlement and termination? Unless there's more to the story (which I strongly doubt) it seems to be combined mix of legitimate but misplaced paranoia and lashing out.

Google invented transformers. OpenAI just released their model to the public first. Good for them, but not exactly impressive research.

Reasoning models are pretty cool, but it was just taking what every body was already doing manually ("and please show your work") and making it automatic. The whole agentic shift is also nice but kinda obvious. But I'm still struggling with hallucinations and context rot all the time and it's becoming increasingly clear that that's not something that can be solved incrementally. We need more architectural breakthroughs like the transformer to achieve something like real AGI. Possibly several more.

> That is, yes, some trauma sticks with you. History shows people are also very resilient at moving on from trauma. Kind of have to be, so that we aren't devastated when we ultimately do lose some family.

This is textbook survivorship bias. If you try hard enough you'll eventually discover a never-ending list of examples where people never recovered from trauma and even outright died directly or indirectly die to it.

EMDR is based on the earlier, broad therapeutic and communications paradigm Neurolinguistic Programming (NLP) [1] of Richard Bandler and John. NLP is broad approach borrowing a lot from linguistics (Chomsky, Korzybski) and cybernetics. It also has been a bit tarnished by its connection to marketing and other things.

From the blog " Gemini CLI spawns a new process within a pseudo-terminal in the background, leveraging the node-pty library...So how does this virtual terminal running in the background show up on your screen? Think of it like a video stream. Our new serializer takes a snapshot of the pseudo terminal at every moment—capturing every piece of text, every color, and even the cursor's position. These snapshots are then streamed to you, allowing you to see and interact with the terminal application in real-time. It's not just a stream of text; it's a live feed."

I think "have players online at any given time" is the tough part there, but it's also the tough part for many non-abstract games. If you look around on Board Game Arena you can see a number of abstract games available, but with many you'll struggle to find any other players.

There are some cool abstract games out there, but they're not super popular. Abalone was mentioned in another comment here. Octi is another cool one. Some like Azul or Patchwork have a light theme but it doesn't really affect the rules, mostly just an excuse for the piece design, which I think puts them in a similar category to chess.

I'm not sure I'd say we won't get another deeply studied game. I mean, if we're comparing to chess and go, it will take hundreds of years to really know if any modern game has that staying power, let alone remains interesting to analyze. But I do wonder if we'll ever get a game that's both deep and popular.

The popularity of RPGs, TCGs, and expansion-based games suggests to me that a lot of people really like feeling a sense of immersion into a "world" that's constantly revealing new "content", rather than discovering new variety within an existing system. Maybe this is just a stereotype, but I also feel like there's a synergy this and a similar vibe prominent in stuff like fanfic, where people like to engage in this sort of generative building on some core ideas. The "pure" or "cerebral" gamer who is really interested in the ramifications of a fixed ruleset is somewhat more rare. Also there are so many games out there now that even cerebral gamers may be tempted to explore new ones rather than digging deep into familiar ones.

This is just to say that maybe some existing abstract games are actually deep, but in order to know that, we'd need people to take the time to analyze them and explore them. Maybe time will tell.

Dominion is licensed in various online incarnations anyway.

With limits on expansions and other rules, it is possible to get Dominion competitive enough to study games and optimize for turns, the original isotropic had a decent ranking and rating system (RIP and add’l shoutout for their implementation of the Innovation card game):

There's no way to identify ahead of purchasing a game whether or not it's got DRM.

Valve has been gatekeeping long before this year's Visa and Mastercard crackdowns. It's been an ongoing problem since at least 2018. They'll flunk a title at review without telling the developer what they did wrong, or even allowing them to resubmit with adjustments. I don't see any sign of them fighting.

You're missing something.

More or less anyone can get to the point of being active enough where their body's ability to absorb calories is a limiting factor. It's not genetic or "some people" kind of thing, everybody has this limit and can hit it and people who are really excited about exercise and do a tremendous amount of it have to have strategies about how to get enough calories in their body on a day to day basis.

It's a lot of activity to get to this point, but some folks have magical thinking about eating.

Anyone absent a significant disability can be active enough to lose weight regardless of diet.

I'm not saying the "go insane and spend most of your free time exercising" is the best course of action, but far too many people have magical thoughts about changing diet or changing activity levels being ineffective for changing body composition.

Getting sat down in a doctors office and being told to do this isn't particularly effective, but that's different from actually doing it being effective.

> I had a friend who would drink a gallon of whole milk a day to maintain weight because he did so much at the gym.

That honestly might be an absorption issue, not an intake issue - you can hit aerobic limits enough for your body to skip digesting stuff & just shove protein directly out of the stomach instead of bothering to break it down.

My experience with this was a brief high altitude climb above 5km in the sky, where eating eggs & ramen stopped working and only glucon-d kept me out of it.

The way I like to think of it is that the fat in your body can be eaten or drank, but needs to be breathed out as CO2 to leave it.

The rate at which you can put it in and the rate of letting it go are completely different.

> I had a friend who would drink a gallon of whole milk a day to maintain weight because he did so much at the gym.

That's around 2.4k calories.

That's like three slices of costco pizza and a large coke. I can do that like 3-4 times and I am not even that fat.

And that's like half to a third of the absolute peak. Like the rock who basicaly works out all day, eats 5-7k calories.

The point is there are people that are eating large fries and triple thick milkshakes as snacks driving from place to place because it makes them feel happy instead of just eating to feel full. And you just can't outrun that.

The feedback is loud and clear and honestly it's fair, though I feel sad.

My intent was to use Apple as a metaphor for interoperability, but it came across as a fantasy post totally disconnected from the real world hell of industrial automation. I skipped the why (legacy hardware, safety, vendor lock-in) and it made the whole post feel naive. That's on me.

As for the AI feel everyone picked up on, You're not wrong. I wrote the original draft and all the core ideas, but I did use an LLM to help review and polish the language.

I see now that was a huge mistake. It polished away all the personal voice and in the trenches, grit that made my previous posts work. It turned a real idea into that slick, empty keynote feel you all hated.

It's a painful but really valuable lesson in authenticity. Thanks for keeping me honest. I'll stick to the gritty, unpolished engineering problems from now on.

> Many, if not most, folks I've met in the scientific community are intensely opposed to this sort of open ended experimentation. NASA has a whole team that insures things we send to other bodies are not carrying any organisms (single cell or otherwise) for this very reason.

That's the scientific community being parochial and self-interested, though. Their priority is writing more papers, and if that means holding the rest of us back, they're fine with it.

This is an extremely common story for anyone who does through hiking on the Appalachian Trail (or Pacific Crest Trail, Continental Divide Trail, etc.). Quite a lot of people start overweight (although I have no idea what the percentage looks like). Almost everyone ends up losing a very significant amount of weight along the way. It is very difficult to stay overweight on the trail. People are intentionally choosing the absolute most calorie-dense food they possibly can, gorging themselves at every opportunity, consistently eating integer multiples of the standard recommended caloric intake, and are still losing large amounts of weight.

This is definitely an outlier case though.

So I'm right and you'd like to change the stakes so you can continue to argue the incorrect point of the author. Just stop. It's possible, it's not a myth, the author's thesis being basically incorrect invalidates the rest of the rambling post, try again next time.

I think you're venturing into denialism territory. There is a mountain of evidence supporting the fact that traumatic experiences have a negative impact on health. See for example the impact of stress on, say, cardiac issues, and even growing grey hair and/or going bald altogether.

As another comment mentioned, sodium ion batteries compete very poorly against lithium when portability is paramount.

But more on that point, it always struck me as bizarre that lithium was dominant in so many areas despite vastly different requirements. For home and grid storage, battery weight is almost immaterial, while it's a paramount concern in portable devices. I think it would be very surprising indeed if one chemistry performed best in all scenarios. Lithium became dominant primarily because it had so much research and supply chain maturity behind it, even if it was suboptimal for areas like grid storage. Glad to see other battery chemistries are getting more investment.

the point of sodium batteries is that for stationary applications (e.g. ups/house backup), we've been using scaled up cell phone batteries for the last decade because the tech space was doing all the r&d. now that we know how good batteries can be, every important niche is getting it's own billions of dollars spent to find the perfect battery for that application

If you can't figure out what I mean, maybe don't be so confident it's dumb?

I'm not talking about pedaling, I'm talking about sitting. Because now my weight combines with the bike. The difference between 215 and 250 pounds is not that impactful.

Edit: There are some differences in weight distribution, but I clearly don't mind those because they exist while the bike is powered too. The issue at hand is the pedaling, and that depends on total weight.
