Moore's law is not about doubling clock speed, it is about doubling the transistor density.
This has continued after clock speed improvements have stopped.
>That's more than what a large refrigerator uses ..
That's partially due to good insulation in modern fridges. After all, if the insulation is perfect, you could run a fridge on 0W (assuming you don't open the doors).
Watts are joules/second - with perfect insulation and doors not opening, the only energy used is the energy used to cool the contents initially. As time approaches infinity watts approach zero, despite the energy consumed initially. c/t -> 0 as t->INF given constant c.
Anandtech's testing showed full load power consumption of 279.82 W (3960X) and 286.72 W (3970X). OTOH the "255W" Xeon W-3175X full load power consumption was 381.08W...
Overclocking chips does tend to cause power usage to spike, yes. That's not exactly a new thing, nor is the increase that surprising. A slight bump to voltage will cause power consumption to skyrocket. Heck, i9-7980XE's at 4.9ghz are pushing 1kW in consumption. Hence why intel's 28 core @ 5ghz demo used a 1700W capable cooler.
The power consumption of an individual core can vary greatly depending on its clock speed (and voltage, which can be reduced when running at a lower clock speed). Putting 64 cores into the same TDP as their 32-core chip is actually pretty easy. If you actively use all 64 cores, they'll be running at a lower clock speed than if you were only using 32 cores.
I like Duolingo because it is so accessible, however I found that it doesn't bring you up to the level where you are able to speak a language in practice.
For instance, I completed the entire French course but I still can't have even a basic conversation when I'm in France.
What do you think is holding you back? Is it that you don't know how to form a sentence, are you unsure to come up with the right words, do you think the course didn't contain the words you need?
In my opinion the Duolingo course does contain the necessary words, phrases and grammar for holding a conversation. But it may not be enough to understand native speakers at native speeds. And maybe you need to be more confident!
I would recommend listening to French podcasts or videos even if you don't understand them. With subtitles if available.
What was holding me back was:
1. Spoken French goes much faster than the French spoken in the course so I wasn't able to understand most of it.
2. To form a sentence to express yourself in real life is much more difficult than to translate a given English sentence like in DuoLingo.
I agree that to be able to use a language you need to do more than just follow a course like DuoLingo; you have to read books, watch television and most important practice it in real life.
Listening comprehension is the toughest part for virtually everyone.
Forming sentences gets easier once you make the switch from translating sentences into composing them without the intermediate step. That's also possible when translating in Duolingo, you just have to concentrate on formulating the idea in the foreign language.
I made that switch in English first, and I seem to do it by default in any other language. It's much easier that way.
I'm sure that a lot is wrong with our current eduction system for teens and that giving some amount of responsibility to teens would be good. But the claim that adolescents are as good or even better than adults when it comes to decision making or responsibility is just plain wrong and there is plenty of physical evidence that disproves it.
When teens reach their adolescence, the functioning of the frontal lobe in the brain is tuned down. The frontal lobe is what gives people self control; tune it down and you become more impulsive, emotional and risk seeking. The frontal lobe only returns to its normal mode when people reach their early twenties.
Would you care to provide any evidence that a publication from the University of Rochester medical center, reviewed by an MD and two RNs is not credible?
I have been looking around for Haskell jobs for a while because I would love to program in Haskell professionally, and what I've noticed that there are very few opportunities and the salaries are quite low.
You can expect to make much more as a Scala programmer, for instance.
The effort of learning Scala vs Haskell as at a professional level would be more or less equal.
