I thought I was clever and tried to enable it from the Apple News web browser so I wouldn't get ads there even when I follow links. But it doesn't seem to work due to third party cookies being blocked. I wonder if that also means

If you are interested in an overview of B-Trees, similar data structures, and how well they work on modern hardware, you may also find the survey bit of my master thesis interesting: See here: https://www.researchgate.net/pr

Or phrased with a bit more seasoning: "Reading from L1 cache is like grabbing a piece of paper from your desk (3 seconds), L2 cache is picking up a book from a nearby shelf (14 seconds), main system memory is taking a 4-minute walk dow

Sorry for the blatant plug, but it might be relevant — in my M.Sc. thesis I surveyed main memory optimized index techniques and also provided some background for why traditional binary search is not very optimized for modern hardware. There

If we can extrapolate from the numbers at [1] (not sure how representative it is) then about 29% of the 233,000 total petitions would be filed under the Master's cap. That'd be around 67,337 Master's cap petitions. [1] http:

Would it be possible to use this to render the current state of a canvas to the console? That's something I'd find very useful for debugging. Edit 1: Looks like they build the memes exactly that way. It still needs to convert the

AFAIK str2 = str will just share the RVALUE-Pointer. I think to actually see shared strings behavior, you would have to do str2 = str.clone or str2 = str[0..-1].
