It will be weeks before this ship is free. Fuel and oil can be pumped out but that only makes up a fraction of the total weight of the vessel. Containers can be unloaded but again the lightest will be at the top so a significant number will

Even if you could unload a container per minute you could only unload less than 1000 containers per day (assuming it's too dangerous to work at night) so at least 3 weeks of continuous helicopter operations.

The cipher only uses two fairly simple techniques: transposition and homophonic substitution. Both of these are covered in any elementary book on codes and ciphers. Combining the two makes a cipher which is tough but not impossible to crack
214.
by barbegal 6y ago
It's pretty simple really. First you need to write out your plaintext and count the frequency of each of the letters in the plaintext. Now choose a set of 40+ symbols to do the homophonic substitution. You randomly assign these to the

It's hard to analyse devices like this. It's clearly not Turing complete but it isn't a Turing machine. It can clearly compute any output for any given input (like a programmable logic array) but it can do a bit more given it

This should of course be 300nm not 300mm referring to nominal feature size on the silicon. Edit: I'm wrong 300mm refers to the wafer size and the later reference in the article to 200nm should be 200mm.

There are no reliable sources that this was a scam or indeed any sources mentioning the building from the time. If this building gained investment on the basis of it being a 480 ft tall building then both the investors are complete idiots a

The M&Ms thing just seems plain weird to me. Communication is a two way street, the touring party needs to communicate clearly what is desired and what is essential. It would be better to spend more time in a meeting with the venue expl

The first blog post only seems to suggest a 10 times speed up. "A simple Ethereum transaction (to send ETH) takes ~110 bytes. An ETH transfer on a rollup, however, takes only ~12 bytes" But the 12 byte number makes some assumption

If a truck produces 1kg for every mile driven then 1.2 million miles would need to be driven over the truck's lifetime. It's a lot but certainly possible (some older trucks have driven over 5 million miles)

Vitalik says that layer 1 optimisations can enable a scaling up by a factor of 100 and layer 2 optimisations by another factor of 100. Does anyone know where the evidence to support these claims is? And if scaling up by these huge factors i

Whats the legal purpose of a letter of intent? If the letter isn't binding then surely it has no real legal power.

I really hate the idea of using a food delivery app to promote a complicated financial product. Retail investors will only be able to purchase IPO shares through the app after making a purchase through deliveroo so maybe they are just tryin

Maybe I should say didn't rather than couldn't. Everyone can rent a server for a few dollars a month to run a node. Most people home laptops are not suited to running a full node as they either have to be always on or are spending

Yes I remember when you could send Bitcoins and your transaction was practically guaranteed to get into the next block. I had fun solving puzzles created using Bitcoin scripts. If you could solve the puzzle you could win some Bitcoins. Tran

It's odd that no one has analyzed the 433 MHz band to find out what is interfering with all these signals. It's most likely to be a bit of misbehaving equipment permanently on a channel.

This is only a dozen users per active starlink satellite. I wonder how many customers each satellite can actually support in terms of both available bandwidth and the ability for the phased arrays on the satellite to target the customer. I

Airbnb has insurance that covers $500. Anything more expensive is your responsibility. To expect them to have insurance that covers more would be a waste of money to customers on a budget. Either get insurance that covers your expensive bel

I thought almost everyone uses some form of interpolation when resizing which would defeat this attack completely. Or are there use cases for not using interpolation (I know it requires less processing)?

Most of the propulsion of a modern turbofan engine comes from the fan rather than the jet turbine so ducted fans can match the speed of a turbofan.

This does work best but the sensor and light source can be on the same side of the skin using light reflected from within. This probably requires more separation between light source and sensor and some clever algorithms to handle different

The transaction was definitely declined but it seems unlikely that this was solely due to the username containing the sub-string "iran". The Bandcamp support engineer only speculated that this could be the cause. The user reports

It works for aviation though. Individual employees are protected by law (at least in some jurisdictions) to whistle blow on their employer and the evidence they provide can't be used in legal proceedings. This has been tested on multip
