PEX pipe is cross-linked polyethylene. It is mostly HDPE, though it is possible to crosslink LDPE as well, creating a slightly different kind of PEX. PEX is much more durable than other forms of Polyethylene.

PEX is not as common for several reasons. To my mind, the two most likely ones are that PEX, while resistant to the Ultraviolet light is not immune, it can't last more than about 2 or 3 months if exposed to direct sunlight.

The second is cost. PEX is more expensive than most other forms of Polyethylene.

So, PEX is pretty much only used for plumbing, technically is almost always a form of HDPE.

You 1) Misunderstood what I was saying and 2) are wrong about the rest.

I am not calling out Uber alone, I am calling out ALL ride sharing apps. Uber, Lyft and the other ride share apps do not earn what they take.

Let me explain.

There used to be cab companies that did everything Uber did EXCEPT for the internet app that lets you summon a car to you. They used old, out dated technology - i.e. phones - to summon cars. The business was ripe for disruption. Uber created new technology that was valuable and worthwhile. It disrupted the dinosaur business. And for that they deserved to make money. 100s of millions even.

But they (including Lyft and their other competitors) were not normal reasonable capitalists. They were all greedy bastards.

Instead of making 100s of billions selling their software to existing cab companies as a normal tech company does, they decided to use their innovation to destroy all the small businesses that should have been their customers.

Instead of letting companies sign up to use their internet service for a reasonable 10% fee, they wanted to own the business while making their employees (that they pretended were sub-contractors - even while breaking the rules about subcontractors). fund the large capital costs of owning the vehicles.

They started their business by overpaying drivers, spending investor money to do so. They did this losing money for years. Then once they had destroyed the competition, they cut the money they were paying drivers and raised prices for customers. Suddenly they became companies worth hundreds of billions, instead of the hundred of millions they deserved.

The drivers went from taking all the risk and having the chance to become wealthy business owners themselves to low paid employees with no health care, no employee protections etc

All those things you talked about Uber etc doing? Car crashes, insurance, liability: THEY USED TO BE DONE BY THE DRIVER-OWNERS.

They DID afford the commercial insurance from one bad ride. Remember, some of them paid a million dollars at auction for the right to run their business. Yeah, they had everything you praise Uber, Lyft etc for.

What happened was this - a tech guy that invented software that should have been something they sold to all the taxi companies instead decided to take them over. All because they wanted to own everything instead of just being a vendor.

They are greedy bastards because they stole an industry from the people that did the work, took it over and made the old workers into low paid contractors. They deserve to be millionaires, not billionaires.

They lost 50% of their pay when Uber took over.

Before the 'ride share' apps, taxi cab drivers was a highly paid position. The badge that let you drive a cab in NYC sold for $1 million dollars. You would drive it yourself 1/3 the day, then hand the cab off to employees. You would make enough in 10 years to buy another badge, then in 5 years get a third, etc etc. Your employees would save up for 15 years to buy their first badge and start the process over again.

Now, those same taxi badges sell for as low as $200,000. Lot of people lost their life savings on them.

The apps charge you money which you think goes to the driver. Nope, most of it goes to the company. They pay the driver barely enough for the gasoline, car payment, and insurance. They expect the driver to make a profit from their 'tip', treating them as a waiter, rather than the owner of the equipment that makes the business possible.

Uber etc are scumbags that basically double the cost to ride. Should they get SOMETHING for the app? Yes. Definitely. But their profit should be tiny, not large.

Glass is significantly more recycled than plastics. In Europe I think the numbers are over 70% of glass is recycled, as compared to around 41% for plastics. (The US numbers are lower - even in California.)

Glass can be recycled unlimited times, while plastic tends to degrade over time. I think the main reason is that glass melts at a higher temperature and you basically burn off the labels and other crap.

Also, glass is a compound of mostly silicon: NaâO plus CaO plus SiOâ. Note short chemical formulas and no Carbon in any of the components. That means it is inorganic, none of the components are poisonous or even similar to things found in the body. Plastics are long chains of organic chemicals containing carbon. They and the things they degrade to are VERY similar to hormones and other things naturally found in the body.

Glass is basically safe, as long as it is not sharp. Plastic are similar to things we know cause medical problems.

Comment Should have tested all 6 common plastics. (Score 2) 38

There really are only 6 common plastics used in the US:

PET: Polyethylene Terephthalate (soda bottles, polyester clothing)
HDPE: High-Density Polyethylene (Milk Jugs)
LDPE: Low-Density Polyethylene (Plastic Bags)
PVC: Polyvinyl Chloride (Pipes)
PS: Polysterene (Styrofoam)
PP: Polypropylene (car parts, medical devices)

Pretty stupid to only test PS, when there are only 5 other commonly used.

That said, I am seriously thinking about abandoning root vegetables. Carrots, potatoes, ginger may taste good, but they just do not seem like they are worth the risk. Stick to the stuff a bit higher up and harder to get to.

Comment logarithmic (Score 1) 157

The charts I saw looked logarithmic. In other words, each successive high is not just larger, but ten times larger.

That is, being 17x as dangerous as something that happened 20 years ago means the next problem should be at 100 x not 17x.

A better comparison would be against the most recent correction, not one a long time ago

Comment Baby stupidity (Score 1) 128

Babies inspire humans in strange ways. We look at them and conceive of them becoming Presidents, Saints, Geniuses. But according to the odds, they are far more likely to become bank robbers, drug addicts, and con men.

Right now AI is barely out of infancy. Yes we can see the lies, oh, sorry I mean 'hallucinations', but we think of them as the anomalies rather than the standard operating procedure.

Some people are disillusioned with mankind and hope this new thing will be better, so they wish they will take over. This is wishful thinking. Nothing about AI indicates it will be morally superior to us. Especially as children take after their parents.

More importantly, it looks to be inferior not just morally but intellectually. AI is not just stupider than us, but we have no path toward any significant improvement.

Current AI technology will almost certainly never get beyond a toddler stage. The signs are clear - graphs showing limitations even with unlimited money, when we fix one mistake we uncover similar other ones (indicating we are bandaging symptoms rather than solving actual causes), etc. etc.

AGI looks to me like the next 'cure for cancer', "flying cars", etc. - it will always be just a few years in the future. Never arriving, just constatly predicted by fools that do not truly understand the limits of what we can do.

(Note, a good argument for flying cars have been here since 1968. Powered Parachutes can travel on a road, no problem. When up to speed, they can deploy the parachute and reach speeds as high as 40 mphs in the air. But with almost no carrying capacity and really low speeds, nobody thinks of them as flying cars despite working both on normal roads and the air).

Comment Lots of mitochondria. (Score 2) 1

I find it unlikely this is a major problem. First of all, mitochondria are in all multi-cellular eukaryote - which is pretty much every living thing you have seen with the naked eye. Plants, animals, fungi, all of it. It wouldn't be a problem for humans, it would be a problem for all living things on planet earth. And we would have noticed that by now.

Second of all, there are hundreds of mitochondria in most living cells in your body (blood cells might be an exception). So if one of them gets screwed up, it dies and the others reproduce themselves. An Ovum has more than 50,000 mitochondria, so even less likely to have a problem and if it were a problem, the embryo would likely miscarry long before birth.

I suspect that if we ever find an example of this, it would be a rare genetic disorder. The kind of things that gets no money because so few people get it.

Comment Wrong on all levels. (Score 1) 57

No one should do this. And no one should use it as an excuse to a cancel working from home programs. Why not? The police officers willing to use illegal methods to pretend to work are not the hero cops.

These people, they would not be working in the office either. They are the guys that by the water cooler talking and bull shitting. They are the ones that take a four hour long lunch break.

The best situation is what happened - the main guy quit. Hopefully the others will be fired too.

This is not a good reason to end work from home. It IS a good reason to update the key logger software with an AI to check for key jamming - both the stupid one they used and to also detect an AI based key jammer that does more than hit a single letter.

Submission + - Your Fresh Vegetables Could Be Sucking Up Plastic Right From The Soil (sciencealert.com)

alternative_right writes: A team of scientists from the University of Plymouth in the UK placed radishes into a hydroponic (water-based) system containing polystyrene nanoparticles.

After five days, almost 5 percent of the nanoplastics had made their way into the radish roots. A quarter of those were in the edible, fleshy roots, while a tenth had traveled up to the higher leafy shoots, despite anatomical features within the plants that typically screen harmful material from the soil.

Submission + - British Transport Police Decriminalize Bicycle Theft (bbc.com) 8

An anonymous reader writes: The British Transport Police (BTP) says it will not investigate bike thefts outside stations where the bicycle has been left for more than two hours.

Commuters leave thousands of cycles on racks outside stations every day, including in specially built bike parks with CCTV. Critics say the BTP policy means those facilities are not secure and theft has effectively been decriminalised.

Any bikes stolen worth less than £200 will not be investigated, neither will car thefts if the vehicle has been left for more than two hours.

1) Learn to code was not a success. People that are not good at coding went into it, did poorly and left. Similar to those idiots that thought going to law school/MBA/Medical school was a good idea if they had nothing better to do.

2) Ai is now reducing the need for coders. In 10 years, something new will reduce the need for what we call AI.

3) Even assuming AI skills are still needed, whatever tech skills will be needed in a decade will likely be new skills that the current tech workers will create.

Hint, for most people the best way to create a prompt for AI is to have the AI craft the prompt itself. Tell the AI to look at the current best practices for the current model of itself and then have the AI craft a prompt to do ????.
