Isn't being "underweight" generally shown to reduce the speed of aging

Yes, people have been trying this the "old fashioned way" since the 90s https://en.wikipedia.org/wiki/CRON-diet

At the expense of weakened immunity, bone health, muscle wasting, and fertility issues!

Probably you both really mean the same thing.

Every gram of body weight needs energy to stay alive. If you are in a caloric deficit, you will lose weight until your energy expenditure matches the caloric intake. If you stay in "caloric deficit" forever you will actually starve by definition.

Properly defining what you mean (comparatively low caloric intake without defining it via the current weight) is actually quite tricky, as your height, body composition and physical activities are all inputs to what counts as a "normal" caloric intake.

I saw reports on that before the GLP1 craze. Calorie reduced diets for lab animals generally increased their life span.

I thought caloric deficits lead to starvation.

Poison is in the dose.

Counterpoint: vertical tabs are way better

Vertical tabs are only better because there is more horizontally space on a as screen and listing things vertical allows you to both gauge the list size and keep a mental reference of what slot a tab was. And those tab headers don’t move because of resizing when the width fills up.

But horizontal tabs are still better. Not technically better or ascetically better. Some other immeasurable, indescribable better.

these are good / accurate, but what's the error-rate? assuming these have been cherry picked, and he made more predictions

I think it's fun. You'll also get the IKEA effect helping you to appreciate the book more

> context a session moves grows with roughly the square of its length

Readme doesn't mention that LLM providers do context caching — your costs aren't quadratic unless you frequently invalidate the cache.

I'm starting to wonder if any of this is better than local newspapers, where there's an editor with oversight over all content...

You can run a lot of these on e.g. M1 max 64gb

Erm that's higher than the healthy BMI range, so not "fairly light". >25 is considered overweight.

It's still lighter than the average American BMI, which is around 29. On average, Americans are classified as overweight.

Yes thats what i was referring to, you're both correct on your respective angles.

My BMI is 28.7 at 181cm and 94kg at 45.25 years old.

Am I overweight, not far off obesity?

You probably wouldn’t say so if you saw me.

BMI is mostly only a useful metric when it is.

I'm with ya at 29.4. I carry a lot more muscle than the average populace, so I'm both high BMI and appear to be "fit" to casual onlookers. But dexa says 26% which is about double what I would like.

How do you conclude you carry more muscle than the average?

The scorer (computer) on my dexa scan noted I carried "elite" (ie high percentile) muscle mass.

> taking backwards compatibility so seriously

Python’s backward compatibility story still isn’t great compared to things like the Go 1.x compatibility promise, and languages with formal specs like JS and C.

The Python devs still make breaking changes, they’ve just learned not to update the major version number when they do so.

Indeed, Python's version format is semver but it's just aesthetics, they remove stuff in most (every?) minor version. Just yesterday I wasted hours trying to figure out a bug before realizing my colleague hadn't read the patch notes.

I would argue that the libraries, and specifically NumPy, are the reason Python is still in the picture today.

It will be interesting to see, moving forward, what languages survive. A 15% perf increase seems nice, until you realize that you get a 10x increase porting to Rust (and the AI does it for you).

Maybe library use/popularity is somewhat related to backwards compatibility.

Disclaimer: I teach Python for a living.

Python it's a language that really good libraries for different domains. like web: django/flask AI numpy pytorch and more. All the ecosystem for scripting and being already installed in most linux distros and on macs. For GUI it has really good bindings for the major frameworks QT,GTK.

> you get a 10x increase porting to Rust (and the AI does it for you)

So, you keep reading/writing Python and push a button to get binary executables through whatever hoops are best today ?

(I haven't seen the "fits your brain" tagline in the recent past ...)

And PyTorch, and Pandas, and, and…

Built and or inspired by NumPy...

Python does not take backwards compatibility very seriously at all. Take a look at all the deprecated APIs.

I would say it's probably worth it to clean up all the junk that Python has accumulated... But it's definitely not very high up the list of languages in terms of backwards compatibility. In fact I'm struggling to think of other languages that are worse. Typescript probably? Certainly Go, C++ and Rust are significantly better.

They don't just deprecate APIs, they remove them completely to make sure you really stop using them.

Python does not take backwards compatibility seriously. 2 to 3 is a big compatibility break. But things like `map(None, seq1, seq2)` also broke; such deliberate compatibility break is motivated by no more than aesthetic purity.

It's very clear that the consumer is getting a worse experience than what is technically possible. There is no good phone-slash-laptop, purely because it's less profitable than locking down the devices and selling them separately.

Looking at the price vs what's inside - sorry but I'll pass.

Allow me to tell you about Samsung DeX.

The real problem is that there is no market for it.

I used it for years with a Nexdock. I just don't really use a phone anymore (mostly Daylight computer, where attaching a keyboard and most mostly gets me what I want).
