Posts like this are why I love HN. I recently wrote a program to find anagrams of a given string (a Countdown solver if you live in the UK).
It includes a really naive method for generating all possible permutations of the string, but reading this post I can immediately see a far better way to do it.
That's my weekend taken care of! thanks to the poster and author.
Forgive me if this is a silly question but when he talks about "beautiful solar-roof-with-battery", is he talking about car roofs or roofs of buildings?
An electric car with a solar roof that charges all day would be pretty cool.
I think it already is pretty overcrowded and this has become a problem that NASA/ESA and others are thinking about. Here is a good ESA video on space debris:
I don't mean the range so much as it sounds like he could be hinting that the car will be capable of being fully autonomous. Considering the price point for the entry level version is ~35k, could we be about to see the first mass market self driving car?
But the fact is we can't stop people cooking up nerve gas and anthrax in their garages if they want to. Just like we can't stop them building their own encrypted apps. Banning it won't stop a determined group.
The IRA were known to recruit top stem students from universities in Ireland during their campaign to make bombs. Surely an entity as large and as well financed and ISIS would have little trouble finding bright young engineers & technologists sympathetic to their cause to simply build their own encrypted services? And then so much for the spooks 'backdoors'
I took it to mean the laser would be based on the station and so could transmit directly to a ground station cutting out the extra 22,000 mile extra hop to the geosync satellite?
I disagree. Although that technology is wonderful, you will still always need the kind the drive and determination to do figure things out for yourself.
It's one thing being shown how to do something, it's another thing to work it out for yourself, in much the same way as studying maths or physic etc.
Apollo 12 was struck by lightening shortly after launch. I wondered initially if this was the reason for the "extra long burn of the ullage motors".
But according to the Apollo 12 wikipedia page: "a small error in the state vector in the Saturn's guidance system caused the S-IVB to fly past the Moon at too high an altitude to achieve Earth escape velocity".
My understanding was that writing tests first is known as Test-First development which is a subset of TDD. TDD allows you some flexibility to write code first as long as the tests 'drive' the development process?
I agree. I think most if not everything he said can be applied to learning almost any discipline. I studied physics at university and I definitely recognize the authors description.
