Most damages are settled out of court. Going to court is more expensive so lawyers on both sides try to avoid this.

I agree, the patent is slightly odd in that it only makes a single claim on the media processing units. I think any multi-core processor would fit the claim of the patent. It seems that in this case the engineer was told to file the patent

The 15 in operation are not the puffy sails that the headline is talking about. They are a rotor design by a different manufacturer. The rotor style sails can save about 10 to 20% of a ship's fuel https://theicct.org/si

The headline is misleading they haven't put anything on a cargo ship yet and likely never will. They have a single prototype yacht which can be seen in this image https://cdn.trendhunterstatic.com/phpthumbnails/454

All modern appliances should have a bleed resistor fitted to drain the capacitor within a few seconds of the power being switched off.

In which cases can you hear phase? I know you can hear phase from interference where there are two sources but I didn't know you can hear phase of a single audio source.

What they don't mention is that orbiting the L2 point is unstable requiring constant manoeuvres to keep the satellite in position. You can think of it like going around the top of a hill. The top of the hill is relatively flat so it di

This also shows how little security probing is performed on cryptocurrencies and smart contracts. It took over a month and a huge bounty to find the bug in this contract. The likelihood of finding bugs in other currencies and contracts is e

This is covered in the blog post. There doesn't currently appear to be any rate limiting. And the rate limit would be tricky to implement because there are times when you need to catch up on the location of a device over a longer perio

If you have an existing Bluetooth device like a Tile then you can reprogram it to emulate an AirTag and Apple users will help you track it https://www.theverge.com/2021/3/4/22313461/openhaystack-appl...

It won't start beeping if you open the tag up and disable the speaker. The beeping is not an anti stalking measure.

You can very easily open the tag up and disconnect the wires that connect to the speaker coil so it makes no noise.

Water is considerably different to air and there is no analogous effect for ground effect in water. Edit: I realise now that you mean hydrofoil as in the boat rather than the submerged wing (it's confusing that they both have the same

It turns out that it is easy to detect that since the signal strength remains about the same, the new MAC appears just after the old one disappears and the contents of the Bluetooth advertisement remain broadly the same. However you do have

The AirTag is based on an nRF52 Bluetooth microcontroller which should have protection against firmware extraction. Last year an exploit was found to bypass this using a glitch in the power supply at the right time in the boot up process. N

I really hate when the press releases don't actually reflect the science in the paper. In this case there are no indestructible light waves and there is no opaque material. There is simply a wavefront which passes through free space (a

So the value is in the content of the guides. How do you write these? Do you get input from the manufacturers or other experts? Fakes can be very convincing and genuine manufacturing processes can be very variable.

I can't see how this is possible. There is no published research on using light to detect blood glucose and blood alcohol with any accuracy. Blood pressure is just about possible [1] if you calibrate with a real pressure sensor but eve

This articles makes absolutely no sense. It uses market capitalisation of Apple and bitcoin to compare the CO2 emissions of an iPhone and a bitcoin transaction which is clearly nonsense. You could calculate the rough CO2 emissions of a 1 BT

It doesn't really work in practise. For example you could have two clients sharing a hard drive with both claiming to independently store the same files. There is no way of actually proving the data is being usefully stored.

I can't see how using photos as a basis for artwork is fair use. If that were the case, advertising agencies wouldn't have to pay photographers or other asset creators, they could claim fair use for transforming those photos and a

Tetris only had the lowest because the cartridge contains just a ROM chip and doesn't have RAM or memory bank controller chips as other cartridges have. I'm sure the halt instruction does reduce CPU power but it isn't that si

This simple code produces a square wave which can sound ok when fed through a buzzer which has a string resonant frequency. The harmonics are attenuated enough that it sounds ok playing notes close to the resonant frequency. For anything el

It's very easy to remove the pull up resistors from most break out boards. The most likely issue you will encounter with trying to connect many I2C devices is address collisions where devices have fixed addresses or at least some fixed

And how much salt would you need? At least 100kg per m3. Assuming the canal is 250m wide you need a 400m section dammed and average depth is 15m then you need 150 thousand tonnes of salt. Thankfully Egypt produces more than 3 million tonnes
