    Disabled cyclist; with one bad choice behind her, needs help with a new bike

    AP has recently done a poll on how much US voters are motivated by fear of the other side winning at November 5th election. 70% of Democrat voters fear Trump winning, 40% republican voters fear Biden winning. It's true that if Biden wins, it's no change but if Trump wins, they fear the worst...

The problem is every country wants to build ever larger data centres. Cerebras is another big player. They build wafer scale AI chips. Their...

    I sometimes feel sorry for Donald Duck. He's used to not paying small contractors so when they took him to Court, he could wriggle out. Now he has to deal to Deep State's lawfare. It can't be easy while suffering from bouts of memory lapses.

    They are still speculating about the source of the cyber attack to attract more clicks. I guess it will be China or maybe netanyahou to hit back at Biden.

    apparently, the usual 'info warriors' have already theorised who controlled the boat and steered it toward the pylon.

    physical gold price this day in 2007 is around $664 per ounce. 14 years later, current price of the same ounce is $2153. It's just an investment. It can go up as well as down. Mortgage crisis 2008-2012, Covid and war in Ukraine boosted gold price. If you bought Tesla shares in or before 2020...

    Most of those who trade on gold don't hold physical stock, even when they deal in physical gold. Money is just a means of exchange. Just look at bitcoin. As long as you can exchange bitcoins for physical gold, then the two are equivalent. The rest is just trade. If war broke out for instance...

    Your example falls into the area of QA in design and manufacturing while the bulk of battery research goes still on their chemistry at the moment.

    The risk factors are well-known though. Larger cells are less risky. The problem is how to maintain good gravimetric density with larger cells. Still, the risk is small compared to ordinary petrol oe diesel. The average car has 30-40 litres of petrol or diesel, or about 400kwh, much more than...

    We paid France £50 millions in the last 3 years. They stopped and slashed about 30%-50% of the boats. That's roughly 100,000 migrants in the same period, £500 each. We are now offering migrants £3,000 to get on that Rwanda plane. Each person on that plane earns rwanda £1 million plus us...
