Tesla was the only EV choice for Hertz

Hertz goes with Tesla The news that Hertz is purchasing 100,000 Tesla's has pushed the stock above $1000 its market cap over $1 trillion. This deal was an excellent move by Hertz and about the best one to get into the EV game that they could have made. #1. The Tesla Brand Tesla is a household brand, yet it has no advertizing budget. Tesla is also struggling to keep up with vehicle sales, achieving a 73% increase in vehicles shipped between 2020 Q3 and 2021 Q3. Hertz has gained a unique association with the Tesla brand.

No one worries about driving someplace and not finding a gas station but finding a charging station is a real concern with an EV, even in 2021. When I got a Tesla Model S in 2016 there were far fewer charging sta...

CPUs and instruction set architecture (ISA)s - Introduction

As programmers we often work several layers above cpu instructions, working with tools that make our lives simple, easy, and stress free! Hahah, of course that isn't the case. We face different challenges at different levels in the system. It really is amazing to think about what goes into a typical appliation level software stack, for example: These millions+ lines of code that a Linux, Windows, or web application is running on top of means the details of the hardware and processor are abstracted to a far away land. Processor features and the Instruction Set Architecture (ISA) often don't matter from a functional perspective. Tools, OSes and other systems take care of lower level details. You might choose a particular processor or processor family for specific attributes, but often as long as you've got a compiler and other tools for that processor you don't really care what ISA is being used. Goal Care about CPU and ISA? Application develop...
