What's the flyest Z80 assembly instruction? "POP AF"

Wrote more about my DOS-Compatible OS, talking about how the kernel and DOS API are structured: medium.com/@andrewimm/wri… There was a lot of inline assembly and register juggling to jump in and out of the system calls. Learning how to use QEMU's debug monitor was critical here.

10+ years ago I fell into a $10M investment fund when I worked at @facebook. It did pretty well and we ended up as the 1st investors in @lyft (IPO-ed last week). A few thoughts about seed investments & how diverse investment teams really make a difference. bit.ly/2CZu5KC

Using a rural internet conn is always good for empathy, but this current time made me realize how many sites are using iconfonts. When we talk about FOIT or FOUT, we should also be concerned about FOUC - Flash of Unknown Character - boxes with Xes errwhere

Started a new wasm emulator using the same WebGL2 memory-mapped-graphics methods from my GB one. Brought up both the CPU and basic rendering in a single night!

As we support more internal use cases at Oculus, React 360 is actually becoming a powerful "React Native for WebGL" core with some 3D/VR functionality layered on top... I'm excited about the new, way-fast, SDF-rendered Views landing soon

Oculus Go early adopters! If you're planning to transport your sweet new headset a lot, I recommend investing in a bag designed for photographers. They're designed to protect lenses, and have removable inserts that can snugly nestle your HMD.

If you host a webassembly demo on a github.io page, Ublock Origin is gonna block it 😭

Opened up the code for the #WASM GB emulator: github.com/andrewimm/wasm… Broke down the arch in the readme, more documentation will get dropped in as I find the time.

First part of my series on building a Game Boy emulator in #WebAssembly : medium.com/@andrewimm/wri… Talks about why I chose WASM, how I handled JS interop, some of the lingering challenges. Up next, a piece on implementing the CPU and basic I/O. Code coming soon!

One #WebVR anecdote I picked up last night adding VR to the emulator: VRDisplay.isPresenting is surprisingly expensive on Chrome for Android – don't call it every frame, it'll slow things down to a crawl

Google's new Poly API is fantastic. Here's a really easy way to pull Poly objects into your React VR app: gist.github.com/andrewimm/a7c4… Just create an API key (described here: developers.google.com/poly/develop/w…) before getting started
