I read a story about Dreame. The founder worked in aerospace, but wanted to make a mass-produced motor with aerospace standards. So he modelled air flow using aerospace tools, built the motor to tight tolerances. Conventional vacuum motors run at 30k rpm, his runs at 100k rpm. Then he standardises on a single motor, for all his devices, robovacs, stick vacs etc, so he gets scale.
Dont be. Source: tried roborock and dream. They are both useless because you spend so much time troubleshooting it dealing with stuck issues you may as well get the cheap vac out.
Datapoint: I've used my Roborock s7 max ultra in three different households (2 houses, 1 apartment) and have had zero issues with this.
It actually was night and day compared to the $1000 equivalent roomba I had at the time. lidar is the game changer in this space, and roomba was complacent with their technology.
I've had a few issues, but they're far from useless. The issues are, e.g. a sofa has tapered legs so the end part is very low to the floor and basically invisible so the vacuum gets stuck there. I've placed a rag that stays there above the leg and nobody sees it or cares except the robot.
If hybrid seeds provide economic and material benefit then the laws should be written to prevent counterfeits, not specifically banning people from replanting.
Presumably if the payer displays and the recipient scans; however that's technically solved by the POS showing the target address, amount, and bill/reference ID; the shopper then scanning, visually confirming the amount, and approving.
A few seconds later the money can have arrived (depending on system):
in Europe today with normal banks and their online banking apps:
the QR-on-POS-screen concept using the standard SEPA instant push transaction encoding, to prompt a <10 seconds confirmed-or-aborted "Echtzeit-Überweisung" (German phrase; the standard works across some borders already though) that's polled by the recipient (to release the customer out of the store), with the obvious fallback of "guess you have to pay a different way".
If for example the self-checkout terminal would just print a bill that then has to be paid by scanning a code on the bill or bringing it to a manned till or such, before the gate releases you from the area just behind the self-checkout kiosks (in response to you scanning the bill at the gate), this could absorb the online banking app friction/delays and offer a fallback of presenting the bill and a backup credit card at one of those kiosks as soon as one frees up in addition to the mentioned human-till cash payment or whatever else they do if your card suddenly misbehaves.
Where I am most of the systems have an option to use static printed QR codes that the payer scans. This is easy to use for small businesses like bars since it requires zero hardware or staff training.
There have been reports of people printing their own QR codes and sticking them over the QR codes for businesses.
why does this arbitrage exist? Why is the cost of energy, the fundamental input into every economy, cheaper in Asia? Tractors consume fuel, fertilisers do too. Human labour is the least efficient at converting fuel into energy. When you dig a little deeper, you'd find an economy structured around keeping rentiers away from the basics: housing, energy and food.
Energy doesn’t come from just raw materials. It takes extraction, refinement, transportation etc in the case of petroleum, or manufacturing, installation etc in the case of wind and solar.
If you mean in terms of general economics, why are some countries cheaper than others, I’m not really qualified to make a statement there. I’m also not talking about if it’s right or wrong. But it is the reality today.
Don’t you think if we understand why energy, the fundamental unit of economics is lower in China we can gain much insight into the rest of the economy? Economists have often praised an energy tax for its non distortionary effect.
SOAP started life as XmlRpc. It was a simple model used in Python. It was a simple serialisation format. It was a micro format and could be implemented in a day. It didn’t cover encryption, signing , routing, cyclic references. But it could be implemented in a day. It’s all text and easy for implementers to fix. Since these were early days of the web, there were no openidconnect, no jwt, no encryption standards. If you used Ruby you couldn’t easily interoperate if there were standards calling for all these things. The SOAP specs were big documents.
LLMs’ design is around novelty and creativity. It was the missing left brain of computation. We should stick to traditional styles of computation for compilation.
What’s there to perceive? Ballmer talked at length about how challenging it was and how often they disagreed on things.
“That's where I moved back to be president of the company and then CEO, and Bill and I went through a year where we didn't speak”
“Basically our wives were the ones who pushed us back together. We had a very awkward dinner at a health club down the street here, but we get back together. But we never really got the right mojo.”
I’ve often wondered about PPP and why China is cheaper. Deepseek provided interesting answers, and it’s nothing to do with pollution or cheap labour. Turns out socialist policies, investing in free markets, cheap education, open competition, public infrastructure result in competitive manufacturing.
