But no linux client for workspaces? Anyone know if one is in the works? I see MacOsx is supported, as well as chromebooks, so it would seem to be a short hop...

on: Curry spice turmeric boosts memory by nearly 30%, eases depression, study finds
Here is the problem: If there is an actual large effect size, then you can detect this in small samples. However, the opposite is not true. In a small sample, spurious large effects are MORE likely, not less likely (outliers have a greater impact in a small sample). See:

on: MSU Scholars Find $21T in Unauthorized Government Spending
But these are adjustments that are larger than the entire (associated) budget. How is even possible? How do poor controls lead to these astronomical errors?

on: Is AlphaZero really a breakthrough in AI?
It seems to me that that someone can prove that the configuration mattered by pitting a correctly configured Stockfish against the configuration used by AlphaZero, and see what the outcome is for 100 games.
I haven't read the paper, but some of the constraint choices seem odd to me (1 minute max per move?).

on: Spam is back
This. I get a bunch of robo calls that appear to be for no purpose - there is no way to get a human on the other end of the phone (they just disconnect when you express interest in what they are selling). It's almost like the call itself is a scam, but not on me - like the call centers that offer this service are getting paid to make the call and not the conversion, so they dial my number and play a recording but have no facility to do more than that. Super frustrating.

on: Even God Would Get Fired as an Active Investor (2016)
They are trying to say "Please don't fire us - even God would have down years!". Although this depends quite a bit on when you start. They start in 1927, if they started in 1932, God might never be fired.

Maybe, you should read it again.
Look: the author has written the essay, when she did not have to. Does that not tell? She has picked details to report that are unflattering to her (and not because she is unaware). Does that not tell?

on: Google Will Stop Reading Your Emails for Gmail Ads
Or, maybe: the extra information gleaned from reading your emails is just not that valuable. Not because they have this via other means, but its just not that valuable, period - whether it comes from reading emails or scrutinizing your browser history. We like to imagine that if advertisers knew enough about us, they'd be able to direct our spending, but I think that is far from true.

If 98% of the sites generate what is rounding error on your sales, then you measure that benefit against the risk that your brand gets associated with a hate speech site (maybe in the nytimes no less). It's math alright, but it means that the brokers are not adding a whole lot of value.

Isn't that the thrust of the article though? They narrowed their ad spend to whitelisted sites and have not seen a drop in sales. If the major sports apparel company stopped paying for endorsements and saw no drop in sales, you might be tempted to conclude that those endorsements are not good investments.

on: The myth of using Scala as a better Java
Not to put words in the parent's mouth, but I think he is suggesting that we (developers) should spend less time creating / analyzing / debating / choosing frameworks and more time thinking about actual end user functionality.

Therein lies the rub. How can regulators or prosecutors discern after the fact that a canceled order was one you intended to have filled?

Or run out of room in the paging file. Your addressable memory cannot be larger than physical memory without a backing store.

Veritas was definitely better than the alternative. I was a dba at the time and it was a godsend.

And that was EMC's "low-end" array. The Symetrix (Symetrics?) I remember being much more expensive for the same throughput.

I used to eat mayonnaise sandwiches when I was a kid. Can't say I would eat these today, but a blt without mayo is not much of a sandwich.
