The problem-solving process requires two preliminary steps: explain and incubate.
The process of problem-solving is first to explain and explore the situation and objectives. We can ask questions and share information, but we can’t propose solutions. Then we require an incubation period for subconscious problem-solving during which we undertake some mundane activity. Then we cooperate on finding solutions.Graeme Simsion – The Rosie Result
Security exists in a continuum. Something pretty obvious for the people in the industry, but which has to be stated more often since there are many parties claiming perfect security or, as in the case of Bloomberg, arguing that better security is just as useless as little security:
Security is not binary, which is obvious if you give it even a moment’s thought. A locked door is more secure than an unlocked one. A door with two locks is more secure than one with a single lock. A locked door with a locked gate in front of it is more secure than one without a gate.John Gruber – Bloomberg on cybersecurity
In the same way a door is more secure locked than unlocked, messaging of any sort is more secure encrypted than unencrypted. End-to-end encrypted messaging is more secure than encryption that is not end-to-end.
The Locard’s Exchange Principle – met in one of the best books I read recently:
NOT EVERYBODY KNOWS THIS – OR CARES PROBABLY – BUT THE FIRST LAW of forensic science is Locard’s Exchange Principle, and it says ‘Every contact between a perpetrator and a crime scene leaves a trace.’ As I stand in this room, surrounded by dozens of voices, I’m wondering if Professor Locard had ever encountered anything quite like Room 89 – everything touched by the killer is now in a bath full of acid, wiped clean or drenched in industrial antiseptic. I’m certain there’s not a cell or follicle of him left behind.Terry Hayes – I Am Pilgrim
The efficiency gain of the electric vehicles is overwhelming. This time Bloomberg gets it right:
About 10 million barrels a day of oil demand – roughly what Saudi Arabia produces now – isn’t merely switched into another form of energy. It’s just gone. Such is the power of efficiency. EVs convert a far higher proportion of the energy from the socket to power their wheels than a conventional vehicle does.Liam Denning – Electric vehicles are overwhelmingly more energy efficient
Thermal energy generates a lot of waste in the form of heat. Only about one in four or five of those gallons of gasoline you pump and pay for provide energy you actually use, and perhaps 60-70% of what statisticians call the world’s primary energy use is really just waste
