Hi, I'm Mike! 👋

You might know me as the chicken-avatar that runs @ludumdare.com. We've inspired many thousands of game creators the past 20+ years, so follow us for that. 😁

As for me, I've worked on dozens of games since the 90's (console, mobile, etc). I focus on "tech" these days. I'm owned by:

Yeah, that does sound right up my alley. I literally wrote a book (chapter) on writing portable game code. Chapter 6, Page 153. 😋

Latest resume is here:

That said, my driver hacking shenanigans was from a personal project, not something I was paid to do. Found these cheap blade servers shaped like a GPU (ASROCK BC-250). The guts are binned PlayStation 4 APU's with 16GB of shared GDDR memory.

Yes. The issue I was tracking involved libDRM on the kernel side, and the RADV AMD driver in Mesa. In short, there's a bug with AMD APUs that if system memory is ever smaller than GPU memory, then it would misreport the available VRAM. Affected both Mesa and ROCM, hence why I needed to dig in libDRM

Not sure specifically what you mean by "engine platform definitions", but I have built custom game engines and shipped products in then. I've created bindings that Unity can use to call native code (mainly netcode), though in general I try to avoid anything C#. I've debugged Linux GPU driver code.

That said yes I've troubleshooted OpenGL ES rendering issues across many GPU vendors: NVidia, AMD, and Intel (GMA and HD), as well as Qualcomm (Adreno), PowerVR, ARM (Mali), and Vivante/Broadcom (VideoCore). I think I even worked with a Samsung GPU, but I don't think many devices ever used it.

Limited Vulkan experience, and I've not touched Metal. I'd say I understand how to work with Vulkan, but in practice I haven't needed it. I have ported rendering code to other "command queue" stye APIs including Direct3D 12, but most of my work has been with OpenGL, OpenGL ES, and Angle.

Well written and it goes further back than I expected. Great job. 👍

Nope! Ugh! I offer proof I was a paying customer, but nope! I'm stuck with a parking ticket for over 3x what I was there to spend! 🔥

Tangentially, I still stand by my previous statement that Qualcomm's job application process sucks.

Make Kasprzak 🦖🍁 @distraction.engineer · 1d

I'm just miffed that it's been months since I've heard anything (aside from next day rejection auto responses). 🤷

Qualcomm is acquiring Arduino, and they're launching a new SBC (Uno Q) combining a Dragonwing SoC with an Arduino microcontroller in the Uno form factor. What implications does this have for makers and education? Quick video covering the news: www.youtube.com/watch?v=CfKX...

I'm tempted to re-apply for a few of the jobs I've previously applied for, ones where my qualifications are indisputable, and I heard nothing for months. One of those jobs I saw was recently delisted, only to learn it was relisted under a new magic number. 🤷

Wild morning (I can't say why), but things did work out 😓. I'm completely exhausted tho, didn't sleep a wink last night. Now I'm multitasking attempting to nap and refreshing my inbox for some/any sign of an interview. 😴😳😴

Ah my apologies. I had assumed you send a new email, or at leas poked any previous one. If you did, then I guess I missed it (oops). I'll take care of this for ya.

Cool, you can file disputes online. I hope its enough that I have receipts from both the grocery store I shopped at there, and the Wendy's I grabbed breakfast from. 🤷

WTF though.

Cool. Sounds like it may happen in either 10.x or 11.x.

Make Kasprzak 🦖🍁 @distraction.engineer · 3d

Agreed. That said plugins do look awfully easy to write, but certainly native support for some form of "this isn't used much please ignore until requested" would be best.

Unsurprisingly, both MSET (msetCommand) and SET (setCommand) are just wrappers around setKey.

*shrug* I guess I just expect to hit some of the limits of Node.js at that scale.

Which is exactly the scenario Northsky may have with its 4000+ user waitlist.

Ideally not, as that means if a few users are uploading video clips simultaneously, that's less bandwidth/latency/pipe for all the other users. Less of a problem with a handful of users, but when you're talking thousands of active users it becomes a concern.
