   Absolutely. Discipline can make all the difference.

   The whole thing needs to be redesigned, so that antivirus and EDR solutions do not require such high privilege. We need a high-performance way for a possibly privileged service to export all the data that is needed for a decision, and then

   I am well aware, but the quotes are timeless for a reason. Not to be cheeky, but "Want money" is exactly how you get to the many routinely broken endpoint solutions that wind up reducing reliability and at times increasing the att

   Security technology harming security? Shocker. We need less monoculture. Trouble is monoculture pays. Write the software once, deploy it everywhere - free money. I manage a simple Tier-4 cloud application on Azure, involving both Windows an

   I agree with almost all of your analysis. One has to be an excellent programmer to write secure code, doubly so in C. I disagree with your conclusion, though. To me, the above means that C FAILS to meet the goal of enabling secure programmi

   I would encourage the community to find a unit of measurement for security. Every defense can be breached, so every defense has an active region, much like transistors. Question is how to quantify.

    I thought wafers were round in part because edges get damaged or contaminated in handling, and one would not want to have a real chip on the edge be damaged that way?

    I think the trouble is that it is not possible to distinguish (through reliable technical means) a responsible overclocker such as yourself versus an unscrupulous actor editing EFI variables in flash. So, because some bad guys/gals fo

    You can. The main thing is that software-based attacks are easier to perform.

    Chips come on wafers. Wafers come in lots. To miss a wafer is to deliver a wafer later than promised, delaying the lot. Intel Israel has never delivered a wafer late.

    Precisely. Loosely speaking, CMOS power dissipation is governed by the equation P = alpha*F*V*V, where V is the voltage, F is the frequency of transistors toggling and alpha is an activity factor between 0.0 and 1.0, corresponding to how ma

    Normal user, agreed. You can find tutorials online, though, for those of us who still remember that the PC was something the user used to own.

    This was true for earlier implementations, but newer ones actually measure power. There is an ADC in there. At least for Intel. Not sure about AMD implementation.

    Yes. Much earlier architectures (e.g., Sandy Bridge) used event counters as a rough approximation for energy consumption. However, these days, we use calibrated current sensors, not approximations. These are rather accurate. And accurate en

    I would be curious to understand the constraints for adding new lines. When viewed as purely a network or graph problem it might seem "easy", but not all waters are created equal. Do they have to avoid high seas? Storms? Pirates?

    Thanks for this comment. The parent comment came off quite ageist. As though the person in question struggled to keep up with the times. In reality, human dynamics play a big role in software quality. I wonder, could it be that the younger

    I agree with the sentiment, but it is harder and harder to find truly "dumb" devices anymore. USB has a complicated (and vulnerable) firmware stack. Monitors have hackable on screen display controllers. Unless you want to go back

    I can recommend Fundamental Concepts in Programming Languages by Strachey 1967. This is an eye opener and a portal into the thoughts of that time. Some ideas are as relevant today as they were back then, for instance L-value versus R-value.
