Why would you think that fusion would give you unlimited energy? All it does is allow you to get energy from cheap, nearly unlimited fuel. You still have to produce, transmit, store, and distribute that energy.

It's great for the environment but for most people not much would change.

What you pay in a free market is (highly simplified) the marginal cost. So even if the setup is highly expensive, in the end, if your fuel is abundant and cheap, your electricity will be abundant and cheap

This is from the post:

> "Monster Green shoppers are likely younger (Gen-Z/Millennial/Gen-X) male, lower income & Caucasian (skews Hispanic)."

Later in the post:

> The scariest part wasn't the training portal or the questionable customer profiling.

Questionable customer profiling is just basic research about their customers.

Seriously, I wish more companies were honest at least internally who their customers are. A lot of problems could be solved if places like Marvel realized who their core base is, accepted it, and made products for their audience.

Marvel knows pretty well who their audience is. The problem is Disney trying to tap into emerging markets, because the stereotypical audience is pretty much saturated. Like, there is zero need to market an Avengers movie to white male comic nerds.

Reading this article feels like seeing somebody you don't particularly like get pantsed, but feeling bad for them because the person pantsing them is an even bigger idiot. Like Monster is not in tech. In any regard. I'm sure that they contract for 100% of their development.

I wouldn't be surprised if their lack of any response is because they literally have noone to deal with this. They can't seem to fill (or hold) some pretty important IT roles:

I had a 5090 some months ago but couldnt get flash attention to work. Does it now work natively? What about 5080?

I think that string length is one of those things that people (including me) don't realise they never actually want. In a production system, I have never actually wanted string length. I have wanted:

- Number of bytes this will be stored as in the DB

- Number of monospaced font character blocks this string will take up on the screen

- Number of bytes that are actually being stored in memory

"String length" is just a proxy for something else, and whenever I'm thinking shallowly enough to want it (small scripts, mostly-ASCII, mostly-English, mostly-obvious failure modes, etc) I like grapheme cluster being the sensible default thing that people probably expect, on average.

I have wanted string length many times in production systems for language processing. And it is perfectly fine as long as whatever you are using is consistent. I rarely care how many bytes an emoji actually is unless I'm worried about extreme efficiency in storage or how many monospace characters it uses unless I do very specific UI things. This blog is more of a cautionary tale what can happen if you unconsciously mix standards e.g. by using one in the backend and another in the frontend. But this is not a problem of string lengths per se, they are just one instance where modern implementations are all over the place.

We use Google meet and it has Gemini transcriptions of our meetings.

They are hilariously inaccurate. They confuse who said what. They often invert the meaning "Joe said we should go with approach x" where Joe actually said we should not do X. It also lacks context causing it to "mishear" all of our internal jargon to "shit my iPhone said" levels.

That's the difference between having real AI guys and your average linkedIn "AI guys." The other post is a perfect example for a case where you could take a large but still manageable, cutting-edge transcription model like Whisper and fine-tune it using existing hand made transcriptions as ground truth. A match made in heaven for AI engineers. Of course this is going to work way, way better for specific corporate settings than slapping a random closed source general purpose model like Gemini on your task and hoping for the best, just because it achieves X% on random benchmark Y.

> autophagy [...] usually takes at least 18 hours of continued fasting to even start

False. That would mean cellular debris would pile up unconstrained for pretty much everybody, which is clearly absurd.

> It is also an extreme cell response that is associated with high levels of cellular stress

Also false. It is a very essential cellular process. Read up on it, please.

You should read up on the literature. There isn't much, but this part is pretty well established.

Personally I'd add 'consume and make tons of fermented food' to that list and also eat lots of prebiotics. Gut health is key to so many aspects of a healthy life - I have to imagine it helps with longevity (and lower stress). Nobody likes having stomach pain!

People love their probiotic pills but I'm not convinced - the amount of beneficial microbes is measured at bottling or production and who knows how many survive by the time they get to you. Not to mention how many survive into your gut once consumed.

Homemade sauerkraut or natto though? Pretty much guaranteed to be teeming with the stuff. And your grandparents and their parents were probably eating it their whole lives. It's a whole forgotten art / science that is thankfully making a comeback.

Anecdotally (obviously sample size of 1 so big grain of salt here) every person in my personal life who I saw live to a super long age and also maintain good mental fitness followed what you are saying above plus made their own fermented food into their elderly years.

At the worst it does nothing for longevity and you end up with more unique tasty food for yourself and your friends :-D

Probiotics fall into the same category as all other supplements: i.e. they can have some short term effects if your diet is really bad or you are recovering from GI disease, but there is not much evidence regarding general health improvement. And you also have the same issues as with all food supplements in that they are not FDA regulated or approved. So even if you think you actually need a particular dosage, you can't rely on what is written on the packaging. A balanced diet is a much better and healthier approach without any downsides.

Even stuff like "don't be overweight" is a maybe. This meta-analysis famously found that being overweight actually has a moderate protective effect: https://pmc.ncbi.nlm.nih.gov/articles/PMC4855514/

sigmoid10 · 8 days ago

This is a BMI-only study and should be treated carefully. They also found a protective effect for one of the obese categories, which seems extremely weird (unless you consider bodybuilders or strength athletes, in which case it would be reasonable). If you replace "don't be overweight/obese" with "don't have excess amounts of fat" (in particular vascular fat) it is certainly not a maybe.

> Fast for short intervals regularly, and longer fasts as they feel good to you.

You can effectively do this every day if you just eat once per day. When I was properly obese, this technique resulted in rapid weight loss. Zero exercise was required to see results, which was good at the time because the not eating part was about all I could handle.

Being in a fasted state is as close as you can get to actually reversing aging. Your body engages in a process called autophagy when nutrient-sensing pathways are down-regulated. When you are stuffing your face constantly (i.e., every ~8 hours), there is less opportunity for this mechanism to do its job.

https://en.wikipedia.org/wiki/Autophagy

sigmoid10 · 9 days ago

While autophagy does correlate with fasting and some studies link it to health markers, it should be noted that it usually takes at least 18 hours of continued fasting to even start and only goes into full swing after 48 to 72 hours. It is also an extreme cell response that is associated with high levels of cellular stress, which might have understudied long term detrimental effects. A simple calorie reduction either by eating fewer highly processed meals or regular intense exercise is much more universally accepted as longevity boosting, because it combats overweight, which is by far the most common disease that shortens general lifespan in the western world. There's really no good reason to force your body through these extreme diets. Don't be overweight, don't smoke, don't drink alcohol, maybe go easy on junk food and maybe do some exercise. And get your regular medical check-ups. Then you're already at the pinnacle of clinical longevity science. There is no actual anti aging drug yet that has a proven effect on humans. Best we have are some moderately promising monkey and small mammal studies, but they generally don't translate well.
