I needed gcc 6 for testing and decided to upgrade the whole system about three weeks ago. It was very easy and it's still pretty stable. I might do a fresh reinstall now...
Edit: Wow a lot of bs going on in the comments. First of all, there's an immense number of ways a DNA strand can degrade, and only one of them splits the strand in two. The relative importance of all these pathways depend on the environment of the DNA, which obviously changes for each and every fossil you have. The global kinetics of "DNA degradation" are supposedly first-order, which implies constant half-life.
Standard SMTP and IMAP but only plaintext is allowed, no attachments. If it works out it will be encrypted by default with a privkey + passphrase upon account creation, and you can of course encrypt on your own on top of the defaults.
Hey, I know someone working on a plaintext email service which should be encrypted by default, without attachments. I can post to HN if/when it's public.
Agreed to an extent, but I think we're going to have to wait and see what the next four years have in store for us. A lot of being Canadian has to do with... not being American. The only place in Canada where I feel there is a definite core identity (completely separable from "not being american") is Quebec.
Harper being so pro-monarchy, insisting on the War of 1812 as being a national foundational myth, trying to assert soverignty in the North seem to be a realization of this identity problem. Also take the current celebrations for the federation's 150th anniversary: the branding completely skips the fact that there were people in the region calling themselves Canadiens for roughly 200 years prior...
Add to that the recent underwhelming documentary on the country's history done by the CBC and the current Premier's own belief that the country has no core identity (being "post-national").
All in all I believe there's a good chance that Canada as you and I know it today will not be around to celebrate another 100 years.
I've often wondered how long Canada can stay an independent country. I doubt it can last 100 more years, unfortunately. Some patriots in 1837 asked this very question as well, wondering why we shouldn't just join the USA and benefit from "more of everything" without sacrificing democracy. They were hanged.
The way Trump has acted towards Canada, talking about NAFTA etc, made me think of someone who has an eye for the territories up north...
The thing with thinking outside the box is that you never really know if you're doing it right unless you hit the "jackpot". I.e. an idea seems obvious to you, but not to your co-workers/friends/bosses/whatever and is usually met with serious resistance from them. Especially in a work setting where you have to convince "non-technical" people. Sometimes it takes more than nice words to get your message across.
Would you consider mathematics to help you in everyday life? I'm wondering because I know some people who argue that it doesn't, while I argue that it does. We might be confronted to a similar issue here?
An Elo score of 1500 is not considered being "really good" at chess.
In real life, you have to make choices. Some choices preclude certain futures while enabling others. Sometimes you can make a sacrifice now in order to "win" later. Etc.
I am not saying that memorizing complex mating patterns for example can be directly transposed to real life decision making. Rather, realizing these exist, and appropriating the patterns of thought that make such analyses possible is what is beneficial.
You are right that we aren't "built to exhaustively analyze game trees", but this is precisely what makes learning chess a good thing: you get to train your mind to do that. Transposing that skill in real life is, I believe, beneficial.
It is indeed, because "time" is not an operator in QM, unlike H or x or p. But from my limited understanding of the time-energy uncertainty relation, you could (as you say) consider it a measure of lifetime - the time it takes for a change in E . So if you get a higher energy, you also should get less change in time, and thus you could probe smaller timeframes.
I might be wrong though. Someone shoot that argument down if you have to ;)
I'm a neophyte player (1250), actively learning. I can definitely see how learning chess to a respectable level (~1500) can help you make decisions in everyday life. I could elaborate a bit but this is a subject about which much has already been written.
You might have heard of the Uncertainty Principle? Basically it says that ΔxΔp ≥ ℏ/2. Well the principle is more general (look up Fourier analysis) and it can be shown that ΔtΔE ≥ ℏ/2 as well.
