Everyone compares Li-ion recycling to starter battery recycling, but starter battery recycling is extracting a single element that makes up almost all of the mass of the battery. There are many different cathode chemistries all in use for lithium ion cells, so the logistics problem is significantly more complicated.

Presumably a specific chemistry will end up winning out for chars, but, IMO, most of the cars on the road now will never have their cells recycled.
> We still have to solve aviation and maritime don’t we?

Hydrogen for aviation is turbocharged stupidity. Particularly when we're making solid progress on synthetic (and biomass) aviation fuels [1]. (Which wouldn't require a global aircraft and airport infrastructure overhaul.)

Errr. So your point is I should be reassuring my friend, by telling him he’s getting fantastic healthcare.

I don’t get it. My friend doesn’t need reassurance. He doesn’t need to take comfort in the fact that France has good healthcare. He’s going to die and he knows it.

I am here just because I want to tell him: if you want to try something crazy, and it may not work at all, there’s this. If you prefer not to, that’s fine too.
Inflation is a tax because capital gains taxes aren't inflation adjusted. The higher inflation, the higher your nominal capital gains are, and you get taxed on nominal gains, not real gains.
Person with cancer: I hope this new treatment works for me

You: FALSE!
I mean the probe itself, which appears to be wire encased in plastic. When I said "left behind" I just meant that the probe is placed below the skin as intended, not that anything remains after the sensor is removed. This is the part that would be considered "invasive."

> That being said, $10/mo is also expensive.

It is more expensive than $0, but if you value your time more than a dollar an hour, the time saved is worth more than $10. I've found I scroll a lot less and have fewer false positive sites where I click in and look around only to find it isn't what my search was looking for.

That is just for the basic search feature. TBH, I haven't even investigated its other features, like lens and the ai stuff.
I get you hate writing unit tests (we all do), but in reality it's a more technically difficult and intricate problem than writing business logic code itself. Testing is the very last place I'd trust an AI.
Wait? In the US you can have "limited sick days"? But what happen if you have something bad and must be off work for 6 months? Who pays you?

> Why not try a moonshot? It’s stupid not to.

I'm a researcher in the biosciences, and know how unlikely it is that these one-off and in-vitro findings are likely to work but I would 100% scour the literature and try experimental treatments on myself if I were in this situation. You've made a good start in looking at some interesting ideas, and there are a few more in the replies. At the very least, it might provide some information that would help someone else. I'm not sure how one would actually go about getting infected with zika.

I'd also try to come to terms with the fact that these are very unlikely to work, and focus on getting my life in order, according to my values and goals. I'd also re-read Epictetus.

However, I will also provide what you are asking for here: If you want an anti-authoritarian biohacker with radical but not stupid ideas - especially about treating cancer look at the late Ray Peat's blog. I've published well received academic papers inspired by his work. But avoid his online followers, they are idiots. Much of his specific ideas and suggestions are basically outdated, but his general attitude towards understanding biology and solving problems on your own is excellent.

However, if it were not me, I would not suggest anything unless they very seriously asked me to do so. I am very much into weird medical ideas and theories, have a biomedical PhD, and yet do not try to play doctor to my friends and family. Sometimes I will offer to share ideas if they want to hear them, but leave it at that.
Just being able to rank domains (and nuke the ones that are usually spam) is enough to make it worth $10/mo for me. This is a tool you’re using constantly, so even small time savings per use adds up to a lot.
> That being said, $10/mo is also expensive.

Back in the beta they planned on launching with a $20-$30/month unlimited plan and they didn't think they'd be able to bring the price down. That was a little too expensive for me so I moved on. I like what they're doing and I'd pay $10/month but I just don't have a use for it anymore.
This hits me in the feels right now. I've been trying to convert from JetBrains to VS Code. And every time I do, stuff like this gets in my way.

For instance: Python. Pycharm: I click on the side for a breakpoint, and then trigger a test to run, and it just works. I keep thinking I'm missing something for VS Code as it never quite works as smooth, but I have better things to do and I move on.

And then I see an article like this which makes it seem like it's not so straightforward.

I have to wonder if responses like this are genuine. Do you really think Hitler came into power on promises of war and mass murder? Do you think that "virtually all politicians" promise things like this?

California squirrels are eating another rodent study finds
Telix https://telixpharma.com that is working on theraputics and diagnostics for gioblastomas (amongst other cancers).

The Australian of the Year (a quasi government annual position) was last year given to Professor Scoyler, who is a leading melanomia researcher. He was diagnosed with gioblastomas 2-3 years ago and was able to make himself a research subject for immunologic and other approaches to dealing with brain cancer.

My friend was diagnosed with gioblastoma 2 years ago, she is very much dependent on steroids and has exhausted the chemo/radio possibilities.

It sucks, but hopefully getting better.

How does that even work? I assume the unique identifiers are generated along the lines of https://zws.im but do they send a different version of the same email to each unique recipient? Or does the watermark get inserted by some email client when copying text?
In this case the other government is the employer.

Robotics has less people involved in and less hype at least in open source GitHub projects. The good part that there is still lot of low hanging fruit to harvest even without touching real hardware. Namely simulators, models (most don't need multimillion dollar rigs) and infrastructure / robotic os projects such as ros.
Agents, LLMs are real cool stuff these days but it is too early to say that this topic won’t fade in next few years if we can’t return to ZIRP.

Robotics on the other hand is entrenched segment and will always be there and will probably gain popularity covertly as automation is de-facto goal of all businesses.

Lastly, keep the Agents as side project(org people getting impressed by agent workflow tells more about them than you) as when/if Agent hype collapses, you are sure to be gutted, but robotics is probably the core business and long term secure. Eventually we will need more robotics(production automation, natural disaster recovery, rising global conflicts, medical surgeries etc.) but we may get these agents replaced by some other ground breaking power efficient models in next few years.

Zika virus is in the wild and in virus banks.

Since no virus banks will hand you out a live virus strain, your best shot is to fly to the rain forest, and get bitten by mosquitoes.

At worst, it gives you an excuse for one last trip to Thailand… you may contract dengue fever and chikungunya though, which is not exactly pleasant.

The case is not a patient, the woman caught the virus cause she lives in Brazil.

I think you are failing to understand how much $2T actually is. That's 200m things you'd need to add up. That's nearly the population of America. It's more than the population of California, Texas, Florida, and New York combined. More than the number of square miles in California. If you started at the southern border of California, you could place a $10 bill side by side (the short side!) while traveling north you'd get more than half way through Oregon! [0] That's the number of things you need to add up, which is still far short of $2T

I cannot express how large of sum of money this is. Only that if you think you understand you're wrong (I do not understand). If you are indeed correct and a large portion of the money is composed of things costing under $1m then we're seriously SERIOUSLY fucked. Because a trillion is a million million.

As with most things, I have extremely high confidence that follows a power distribution (go look up Pareto). So there's going to be thousands of things more than $100m in cost.

So I'm extremely confident that if you're picking 10 examples to show on screen and of any single one of those values is under $10m then you're either grossly incompetent or showing rage bait. Because even $10m is chump change when we're talking about these numbers. You certainly aren't providing any meaningful communication to your viewers. At best you're accidentally grossly misrepresenting the problem. While I'm a fan of Hanlon's Razor, extreme incompetence in your domain of expertise is no different from malice.

[0] a bill is 156mm x 66.3mm. California is 1,220km long. 1220000/0.063=19,365,079. Oregon is 580km long. $2T is so much fucking money you could place $100 bills side by side along the length of California and if you did this a thousand times you'd be $63.5bn shy of $2T. If you did it 1033 times you still be $1.5bn short.
I think there's some truth here, but part of the change is that people have become aware they are/have to be a brand. Like MKBHD is his initials and a brand.

In the past, I think it was the same thing, like actors typecasting themselves, but named differently.

Also, I think the internet has degraded brands. Getting a decent brand to show up on amazon is sort of ridiculous since no name upper-case "brands" get equal or better billing, and better (fake? nudged?) reviews.

> LLMs have proved amazing facile with language.

If you took a transcript of a conversation with Claude 3.6 Sonnet, and sent it back in time even five years ago (just before the GPT-3 paper was published), nobody would believe it was real. They would say that it was fake, or that it was witchcraft. And whoever believed it was real would instantly acknowledge that the Turing test had been passed. This refusal to update beliefs on new evidence is very tiresome.

Hydrogen is not a source of energy, it is a carrier. You have to create hydrogen gas from water (or as is done today, from fossil gas). This takes energy. This energy can just as well be used to power the thing directly. Which is significantly more efficient.

https://pbs.twimg.com/media/D0MuwO9V4AEGbUo.jpg

Hydrogen is brought up as a potential storage method which may work, but it makes metals it touches brittle. It is not like storing fossil gas. There are ways to limit it, but it has costs.

Hydrogen in cars also uses expensive metals, platinum in the fuel cell.

2. If you aren’t able to work, you need to use a PSSL day.

What’s not fully clear to me is whether the expectation is normally that you work on a PSSL day, as it seems to be the case that you get paid on those days whether you work or not.

Could it be argued they're producing big picture tech demos of robotics ideas?

I'm fuzzy on how much their in-house robotics work to-date is actually in use.

Absolutely, their hardware and software are widely used across numerous robotics companies, but keep in mind the number of actually successful robotics businesses is still super small and a minority of those you hear about in the news. (and how much are those companies actually doing with "agents"?)
In my experience nearly every decent product ive ever wanted I either sought out myself first or found through word-of-mouth, almost none of it through marketing materials which these days I completely disregard because it is 99.99% bullshit. And I believe word-of-mouth would be even more effective and useful if mass advertising simply didn't exist to pollute peoples thoughts and preferences with a bunch of deceptive marketing garbage. I firmly believe over 99% of marketing could be easily replaced by simple word-of-mouth if it wasn't drowned out by marketing materials and advertisements.

Sadly, aviation is looking like only hydrocarbon combustion will work for anything aside from very short-haul flights.

No battery breakthrough will get around the fact that medium and long-haul planes get the bulk of their range from the fact that they get substantially lighter as they burn fuel. Short-haul routes and trainers can be all electric ( https://byeaerospace.com/ ).

We'll probably end up with something like "green" hydrocarbon synthesis--at substantial cost increases. The vast bulk of aviation will never be de-carbonized in any foreseeable future short of something akin to "Mr. Fusion" from Back to the Future.

There's good hope for ammonia in maritime. Man in Germany has had working ammonia fueled gas turbines on a variety of vessels and routes for years with forthcoming retro-fits available this year. https://www.man-es.com/discover/two-stroke-ammonia-engine

Ammonia won't work well in aviation due, primarily, to its very short/slow combustion wave-fronts and low combustion temperatures, but also due to its lack of specific energy density with storage infrastructure that's light enough to be airworthy. It's "do-able", but a very distant "2nd fiddle" to even lite/green Jet-A (kerosene) synthesis.
iPhones, Pixels, and Samsung phones have been defaulting to HEIC for around five years now, so it’s unlikely that compression alone would prevent tracking dots or other unique noise or patterns from being preserved. Steganography is a well-established technique that can definitely survive through photographs, even under compression. Variations in fonts or typography could be used for tracking too. There are plenty of creative ways this could be achieved.

> That would be next level corp spyware

Would it be? I was implementing similar stuff for a crappy PHP forum 15+ years ago that wanted to track which users were sharing private posts outside their community. It started with screenshot-tracking by embedding small 1xN base64 images that were almost completely transparent except for some tinting on each pixel to represent a 1 or a 0 bit at the edges of several elements where they wouldn't be noticed. That didn't survive jpeg compression or photos, so I added text transforms that represented tracking bits as well. Things like one vs two spaces after a period or an expanded contraction would correspond to a bit of the ID of the user the text was served to.

That worked fine since the site was mostly prose, but I couldn't help but think about generalizing it to encode tracking bits as page styling information as well. Never ended up finishing that implementation because I got too in the weeds trying to account for rendering differences in customized user agents by adding error correction bits to the IDs. That way it wouldn't matter if a few styles were overridden or obscured.

I don't think any of these ideas were particularly novel or difficult to think of, so I'd expect plenty of independent implementations over the years. If they do their job right you'd never know about them, so there's likely more than you expect.
Hydrocarbons are already good at that. Its the fact that the carbon comes out of the ground instead of the air that is a huge, pressing problem. Use the excess electricity to split water, and bond it with carbon in the air.

Hey, at least git owns it by calling the shell commands "porcelain" (with git itself being the plumbing -- https://stackoverflow.com/questions/6976473/what-does-the-te... ).

Yeah real wages are the same as they were 4 years ago. At the same time real returns from the stock market are up 10%. [1] And this isn't an isolated event. Since 1979 (not cherrypicking, that's the first date of the FRED table you linked) real wages are up 10%, and real returns from the stock market are up 3200%.

There's something just not quite right about these things. Imagine telling somebody in 1979 that, with the current system, in 50 years they'd be earning 10% more but the stock market would be up 3200% more! Nobody would accept this (well unless they had a ton of money to dump into the markets), but with inflation and everybody thinking "wow I'm earning thousands more than last year - think of where I'll be in 20 years!", all of this is made invisible.
