Microsoft has a serious and ongoing PR crisis, and not just for historical reasons (90s antitrust, etc). There are undoubtedly many highly intelligent, well-meaning people working there, but the ongoing occurrence of highly-publicized custo

That's more or less true only if you are retired & not re-investing dividends (not regularly purchasing new, high-basis lots). The key problem is the one that loeg mentioned: on a $500k+ account you will likely be paying >$1k in

One obvious issue with this post is that it uses historical S&P500 returns from a period of high performance. To be predictive, it would have been helpful to also examine expected future returns for the next 10-20 years, which are gen

Like it or not, IMO there is little reason to expect this to have a material effect on the stock price, as it is not a product recall, and it probably will not seriously impact Intel's competitive position (given its main competitor is

While not exactly what you were suggesting, DDR4 ECC DIMMs and SO-DIMMS are already "pin compatible" with non-ECC modules. So it is straightforward to design a CPU and motherboard that support both, with a control bit in the IMC a

Well, for the past 4+ years "arbitrary kernel code execution through mounting a malformed FS" has been considered a major security issue, and a lot of effort does go into finding and fixing stuff like that through fuzzing, code au

I would argue that we pretty much reached peak single-core x86_64 scalar instruction stream concurrency ~6 years ago with Sandy Bridge. SIMD has gotten wider since then (AVX2, etc) and there are occasional new instructions for certain workl

Yup & the most recent flash memory consumer price drops are due to a process shrink plus 3D die stacking, rather than just MLC/TLC. Stacking can and will be used for DRAM as well but 3D DRAM-based products have not hit high-vol con
