How a CPU works: Bare metal C on my RISC-V toy CPU

[ comments ]I always wanted to understand how a CPU works, how it transitions from one instruction to the next and makes a computer work. So after reading Ken Shirrif’s blog about a bug fix in the 8086 processor I thought: Well, let’s try to write one in a hardware description language. This post is a write up of my learning experiment. I’ll walk through my steps of creating an emulator, compiling and linking C for bare metal, CPU design and finally the implementation of my toy RISC-V CPU. implement a CPU in a hardware description language (HDL), code must be synthesizable (except memory), simulate it, and run a bare metal C program on it. While I had plenty research...

Why The Fire Hunter Is Your New Anime Obsession

Spend enough time in anime fandom and you hear a common refrain: "They don't make shows like they used to anymore." Do they? There's plenty of great anime still being made: Fall 2022 alone brought an incredible bumper crop of anime series across multiple genres. Some may prefer the masterpieces of the past, but those masterpieces were exceptional even then. Even so, it is indisputable that certain kinds of anime are simply not made anymore. Original anime series are scarce. Modern shows rarely last beyond 12 or 13 episodes. Robots drawn in traditional 2D animation, outside of specialist studios like Trigger or Sunrise, are rare. Even the newest "Gundam" series, usually the industry standard for 2D giant robot shows, struggled...

How I Met Your Father Season 2 Brings Back A Familiar Face — Could He Be The Father?

This piece contains spoilers for the season 2 premiere of "How I Met Your Father.""How I Met Your Father" proved right out of the gate to be a worthy successor to "How I Met Your Mother," and this second season is looking to be no different. Balancing millennial realism with sitcom hijinks is far from an easy feat, but the show's been able to charm from the beginning.

We're talking, of course, about the appearance of Robin Scherbatsky and how her encounter with Sophie (Hilary Duff) serves as a metaphorical baton-passing from one hopelessly-romantic...

Select-an-Effort: Under the Bathroom Sink

One of the rooms which tends to get overlooked and overworked is the bathroom, so we will be spending some time in there today and tomorrow. The focus for today’s task is the space under the bathroom sink(s). There are a couple of things to consider when it comes to bathroom storage: If you have “his” and “hers” sinks, focus on the one with your stuff. If you have pedestal sinks, go to the area where you keep the items that you might otherwise keep under the sink (e.g., extra toilet paper, toiletries, cleaning supplies, etc.). A lot of items end up under sinks. Common examples include: Feminine protection products Toilet paper and boxes of tissues Overflow supplies of shampoo,...
