Short answer: No. E.g. if you buy 'shares' in an index (via an ETF), you're effectively buying a weighted basket of the component shares in the index. If the individual shares are overpriced then so is the index as a whole. H

Shorting the bubble would be more like: 1) Alice owns a property. 2) Bob borrows the property and gives Alice an 'IOU one house'. 3) Bob sells the property. 4) Market falls 5) Bob buys the property back, hands it back to Alice, an

SSDT is insanely slow rebuilding our database model in the 'background'. And it's clearly tripping over itself somewhere because system CPU and IO is typically near zero while these rebuilds are running. Very annoying.

The other factor here is that the increase in up-front development and fabrication plant costs has been absorbed by economies of scale, i.e. the semiconductor market has grown massively in recent years, and it's debatable how much furt

Moore also specifically referred to the cost per transistor, a metric that is complicated by the increasing costs of fabrication now that the low hanging fruit has long gone.

It's also often useful to think of the true distribution of the underlying system/dynamic in question, and to consider a histogram as a sample that therefore has sample error. E.g. if the histogram's tail bins have very few s

Still got three A500s in the garage. One was recently saved from going into landfill and is in pristine condition. Still got the original 'Simpsons' packaging and discs.

Minified js doesn't need decompressing whereas gzip would, but I'll admit it's probably a minuscule amount of CPU even on a smartphone, especially if you cache the decompressed version.

Yeh, I think there are probably a few different ways you could 'slice' up the body of the pdff. E.g. I mention using sloped ends to the segments to reduce the amount of pdf area outside of the segments, which would reduce the expe

Very cool. Note that my C# version is fixed to use 128 segments based on George Marsaglia's original calculations; Calculating them dynamically for a given PDF is an impressive achievement indeed. E.g. I did wonder if there was a more

One could say that the high level source code is elegant, but overall its use of log and sqrt invoke a lot of complex machinations (inside the CPU).
