While those are indeed major factors, there are others that come into play. For example, a change in your thyroid behavior can cause a loss/gain in weight without changing anything else.
It seems like you are saying that it would be fine for someone to eat nothing but potato chips and candy bars, as long as they:

a) don't eat so much they get obese, or
b) take an anti-obesity drug so they don't get obese

Which is ridiculous. They would still get sick and die early due to lack of nutrition.
Twitter is kind of ok for what I need from it.

Also mobile Web is good enough for most forms over data kind of applications.

> Why is computing like this?

IMHO because the happy path is easy, but guarding against error conditions, and then either taking action or advising someone of that outcome is horrifically hard. It's hard not only because it requires the experience to know that not every HTTP request is 200, not every method call is a-ok, not every disk has plenty of space, nor permissions to write to whatever, and even with a huge checklist of the way things go toes up, a disciplined library author can have 250 different illustrative return codes that the caller can then throw in the trash, iterate all the way up the call chain and everything has to align perfectly for the actionable error to reach the end user

That especially plays out, in my experience, in programming languages that place the "please check the return code" upon the programmer, as opposed to ones where errors are more "in your face," but the joy of `try { doSomething(); } catch (ex) { /* lolol */ }` makes it all too easy to ship something because It Works On My Machine

Being on the pointy end of your checklist makes me have a great deal more empathy for users of my software, but I am merely one person who thinks swallowing errors is a crime against humanity

I think most Linux systems have this too. GNOME definitely, for the applications pinned in the overview, and I would be very surprised if KDE didn't do this too.
I’m not sure there are any good ways of tracking sources of data through the model.

The best way would perhaps be to
do it backwards: dream up 2-3 answers. Search for support for those answers after they are created by looking up individual facts in them in reference sources like Wikipedia. Then respond with the answer that could generate sources.
> one of the foremost experts of fat metabolism.

What makes you say that? In my experience, there are no 'experts' in empirical fields who are no themselves deeply and practically engaged with actual research. Being well-read does not make you an expert. Writing blog posts and appearing on YT doesn't make you an expert. Critics are not experts. To be an expert in anything you have to get your hands dirty.

Nothing I can see from this guys publications or bio make it seems like he's an expert in human fat metabolism at all, let alone a 'foremost' one. I base this on a fairly cursory survey, so I'm happy to be corrected. But convincing corrections would absolutely require details regarding what he has contributed to the field.
For chatgpt, when you try to teach it some few-shot learning task it's painful to watch at first. It makes some mistakes, has to excuse itself for making mistakes when you correct it and then try again. And then at the end it succeeds the task, you thank it and it is happy.

It doesn't look so different than the process that you describe for humans...

Because in its training loop it has to predict whether the conversation will score well, it probably has some high-level features that lit-up when the conversation is going well or not, that one could probably match to some frustation/satisfaction neurons that would probably feel to the neural network as the qualia of things going well.
when I was mostly doing ruby, with the occasional foray into python, I would have agreed with you. but having gotten a python day job and using it as my primary language for the past several years, I think there are features that python got right and ruby did not, as well as vice versa of course. the top one is the way the two languages handle modules and namespaces (ruby lets you reopen modules, which is nice, but python lets you easily see at the call site whether you are calling a function from an imported file, which is amazing for large projects), but I also miss introspectable doc strings, and syntactic support for type annotations (which are also introspectable at runtime!) when I'm writing ruby these days.

How was it socially isolating? I’m curious because I exercise and diet and this is not my experience. I understand it being challenging though.
The first time I tried ketchup after strictly avoiding added sugars for several weeks was a WILD experience. It tasted sweeter than maple syrup. I used to douse my food in ketchup and now I can't even eat it on fries because it's so sickeningly sweet. I noticed the same with most bottled salad dressings and sauces (barbecue sauce and honey mustard being even more egregious than ketchup).

Obesity is 100% caused by food is plentiful, with a catch....

There has to be excess calories in the first place, much like there must be oxygen for there to be a fire (don't you try to get florine involved in this).

Humans eating behavior seems to be driven by the first few years of our lives. If you eat like garbage as a kid, it follows you into adulthood. The US was (somewhat, there are still plenty of other even fatter countries) first with the TV to counter advertising that taught us that Trix was part of a balanced breakfast and that we should carry a coke wherever we go.

Other countries likely had confounding factors that slowed the excess calorie uptake. For example common traditional meals that were only replaced slowly. Other things that can tip the scale are things like higher walkability in their cities.(for example higher walkability in the US correlates with lower body mass).

But as stated, those confounding factors only slowed the fattening, it didn't stop it and the EU now is growing in weight just like the US did in the past.
> M1 has huge L1 cache, huge reorder buffers

At first I thought it would be the close integration of memory, but it seems the consistent instruction size makes the reorder buffers a lot simpler to implement than for x86, so you can get a much larger aarch64 reorder buffer for the same area of an x86 (amd64) one.

Weekend Health | Founding Engineer | Onsite/hybrid in San Francisco | Full-time | $150-200k + generous equity

Weekend Health's mission is to make healthcare more accessible, especially for those with chronic diseases like obesity, diabetes, and heart disease. We're pre-Series A with a small team, but we've already grown to >$10m in ARR and have been profitable since July (only 7 months after launching).

We're looking for motivated full-stack engineers who are passionate about using their eng skills to make a positive impact in the world. You'd be building software that allows patients to get insurance to cover medications that would otherwise be prohibitively expensive while working with a tight-knit team of serial entrepreneurs and all-star performers.

Our stack: TypeScript | React | Node | CDK

As an industrial EE dealing with hydraulics of much larger scales than those on a garbage truck, those other functions do not require significant power to operate when compared to actually accelerating the vehicle and cargo up to speed (and then slamming on the brakes/regen again for the next stop).

The engines in diesel garbage trucks often run at idle when those hydraulics are working, lifting a 100 kg residential can or a 1-ton dumpster through a few meters of motion is not noticeable to a 350 HP diesel, accelerating 30 tons of truck and trash in the same amount of time is why they're equipped with so much more engine power.

My US doctor recommended it to me last week and said there was a way for it to cost about $200/mo if I want to do that.

I'm supposed to book a follow up appointment after I've read about it, so I guess I'll find out what he means then.
Yeah but majority of employment contracts are 'at-will', so either party can say bye-bye anytime they want. I work, you pay me - pretty simple, lets keep it that way.

> Why are they using garbage trucks to plow snow?

Fewer vehicles to acquire, maintain, store, etc. That seems self evident.

Further, the scheme works fine. The issue isn't whether plowing snow and collecting garbage with the same vehicle is a workable idea. The issue is that there isn't an electric replacement available yet.

Maybe you can plug it in. But then you'd be tethered to the computer.

However, Mac might not have low enough latency / high enough bandwidth for best experience. My thinking is that it will be an ultra-optimized highly integrated device designed to do just AR/VR, and that's also why it can beat all competitors which interface with standard PCs. I have a very high-end VR headset and GPU, and it just isn't good enough. Apple has to make some miracles here.

https://slimemoldtimemold.com/2021/07/07/a-chemical-hunger-p...

TLDR: The modern obesity epidemic is mostly a mystery, things like higher caloric food, western diet bad don't tell the whole story. Most likely answers are chemical contaminants in our foods and water i.e. lithium or PFAS chemicals. Interestingly enough both wild animals and lab animals(rats) have been getting fatter over time as well which clearly invalidates the "bad diet" theory. The Human body has a lipostat, you "natural weight" mechanism if you will and it seems these contaminants increase the lipostat and this results in widespread obesity.
Considering the benefits of good diets and exercise, I think it's worth it not trying to hack or shortcut our way to a healthy life with weird drugs or whatever.
So you agree, the overwhelming impact of diet on health is from reducing obesity?

And surely you also agree with the science that we now have drugs that are far more effective at reducing obesity than any diet known to man.

This piece makes assumptions that turn this into a very boring discussion with little depth.

How effective is preliminary learning vs on-demand learning? If I can have 80% of the conceptual understanding in 1/10 of the time is that a good trade-off?

For preliminary learning, how do you know which knowledge will be useful in the future and which will be abstracted over?

How fast is the field moving and what do you want to focus on?

For example, someone asked on the ML subreddit about theoretical ML research and many comments said theoretical research was unnecessary:

"But, regarding the value of pure ML theory research e.g. convergence bounds, versus practical ML research e.g. quantization methods, my personal feeling for quite some time has been that purely theoretical ML research has been predominantly bunk. Machine Learning is so high dimensional that things that can't be proven universal can be nearly guaranteed probabilistically, and things that can be shown to be possible can be staggeringly unlikely; for example, just because the No Free Lunch theorem exists, doesn't mean that Adam won't work in the vast, vast majority of cases."

https://www.reddit.com/r/MachineLearning/comments/101qbfl/d_...

This topic is extremely grey, and blunt arguments like "on-demand learning is ruining the tech industry" are not interesting.

I recommend you watch this talk by Laurie Voss where he (They?) explains that fundamentals are always shifting. What you consider "conceptual understanding" now was a tool many years ago. Tools solidify into the new generation of concepts over time. One controversial point he makes is that at some point, new developers will not know HTML and that's ok!

Notably, this is (presumably) why our bodies often think it's a very good trade-off to turn everything down instead of burning fat. Fat is important long-term storage that might be what gets us through the winter starvation, and storing/burning it is a lossy process -- turning down the tap on our energy usage for a little while, however, might be all we need to get through a lean few weeks.

> Technically, they aren't trained that way, their opposite recognition AI is trained that way.

No, they are trained that way. These aren't GANs or anything resembling that. There is a reinforcement model that is build from expert human guidance which is then used to fine-tune the LM.

From the HuggingFace explainer page I linked above: [there are] three core steps:

1. Pretraining a language model (LM),

2. gathering data and training a reward model, and

3. fine-tuning the LM with reinforcement learning.

Read https://arxiv.org/abs/2203.02155 if you want all the details (although the HF explainer is easier to follow). From the abstract of that paper:

> Starting with a set of labeler-written prompts and prompts submitted through the OpenAI API, we collect a dataset of labeler demonstrations of the desired model behavior, which we use to fine-tune GPT-3 using supervised learning. We then collect a dataset of rankings of model outputs, which we use to further fine-tune this supervised model using reinforcement learning from human feedback.

There is no "opposite recognition AI".
PFAS chemicals are a likely culprit, their presence increased dramatically as obesity rates took off and they are stubbornly persistent in the water and food supply.

I think it's pretty well agreed upon in the medical community (and proven) that a healthy diet (lots of fruit and vegetables, not too much sugar, etc) and regular exercise leads to better health.

“when lifestyle changes aren’t enough.”

People don’t want to hear it, but we do nobody any favors by pretending this is more complicated than it is. It’s actually pretty simple. The solution is to adjust calories in vs calories out. Fast a few days a week. Cut out bread, sugar and other simple carbs.

We don’t help alcoholics or opioid addicts by enabling them with statements like “when not getting drunk isn’t enough…”

As a user - I don't want web based "apps" - I actively avoid anywhere I can.

I want native apps - they better align to my operating systems native UI/UX, are more performant, have less (potentially insecure).

Yes - Platform APIs absolutely should be made available to varying technologies where security is less of a concern, But I'll take a few high quality apps over a plethora of 'creative' web-apps any day of the week.

If you only need a website - just have a website, you don't need an "app" to order a beer at the pub.

In my experience a large majority of people that want other people to use web-apps / glorified chrome wrappers are those that write them and often (but not always) have a vested interest promoting getting their product/features out the door over quality, performance and security.
Encryption was export-restricted until 1996.

Actually that isn't really relevant - most of the systems the authors are talking about (and that they worked on) would have been running on enterprise or campus LANs, and it wasn't totally clear (at least to the sysadmins at the place where I worked) whether it was even legal to connect corporate networks to the internet at that point in time if you weren't a govt contractor.

Based on what I recall, most of the security threats we were worried about had to do with corporate espionage and information theft, and would have required physical access to the network. In that environment, encryption isn't important in the same way as it is on today's Internet.
