> It seems to me that there's little reason to upgrade [to ECC RAM] if there have been no issues in the past. One of the benefits of ECC RAM is the ability to detect single and double-bit memory errors. In the absence of that capabi

So using your same rhetorical style, let me respond: - While the error rate of memory is "low" (however you define that to mean), it is not zero, so the risk of memory errors persists. - A machine without ECC memory has no reliabl

I'm in an area where Google Fiber offers 2 Gbps service. Unfortunately, for whatever reason, the 2 Gbps service doesn't allow for (or didn't, when I looked into it) the use of your own routing equipment -- you have to use the

Virtualbox VM encryption can be useful if the host hypervisor is compromised and the unauthorized party uploads data on disk that the host can trivially access (as is frequently the case with ransomware).

The only way I've been able to get good virtualized 2D performance without providing a GPU directly to the VM has been to use a display manager where you can disable compositing. Otherwise, you end up having to use a software 3D raster
