5 intersecting rotating cubes, cpu-rasterized in correct order thanks to a custom depth buffer (aka uint32_t[width*height]). Right side shows the actual depth buffer values. This works at a miserable ~25fps, but at least it works 😅

I tried rendering in 4K, but the Nokia N95 runs out of memory (although rendering the frame in tiles and stitching it together should make it possible). 1080p, however, works. This video shows a 720p render with four compositing passes: Color, Alpha, Normal, and Z-buffer

** Sega Genesis 3D engine update 4 ** Never can leave a good rabbit hole undug ! .. updates since last update : Changed frame buffer from a VDP tile friendly buffer to a linear buffer which needs CPU translation , which speedup drawing a LOT not having to worry about tile boundaries albiet slows buffer sending to VRAM. The interior filling of triangles now is running at 1.5c ( 68k cycles ) per pixel ! however sending the buffer is twice as slow per byte as we need the CPU to send the buffer to VRAM to write to the tile format the VDP needs, rather than DMA directly to VRAM . Overall speedup 25% + as the drawing speedup is much greater than the frame buffer slow down. Optimised Line drawing and Triangle filling -near optimal now for the linear frame buffer. Triangle drawing might get a little bit more yet. Quad drawing is next on the list as that will speedup drawing quads. Some gains will come from been smart about partial clearing of RAM buffers and partial sending to VRAM buffers, rather than send the whole buffer. Vertice rotation and projection needs a lot of optimising .. i expect good gains to come from this - this is all in C at present and all calced in real time. Line and Triangle drawing are in assembly but all vertex manipulation is in C. #SGDK #MegaDrive #SegaGenesis

How to have macro positioning advantage? Avoid the Core (Miolo). I call it "Miolo" in portuguese. Try to be at the opposite side to the Core. Not always you will be able to do it, but at least you have to understand the pattern and how it works. Pause the video and read! 1/7 🧵

Quant on Polymarket turned $313 into $296,000 in one month - and it never predicted Bitcoin's direction once. 65% win rate on 15-minute Up/Down markets. The edge wasn't the forecast. It was the order book. Wallet proof: It's the one thing retail never sees and bots live on: full bid/ask depth on any BTC/ETH/SOL Up/Down market, at any second in its history, down to 300ms - Binance depth beside it, replayable tick-by-tick on real fills. I've been pulling it from PolyHistorical Here's why it matters. Bloomberg ran the numbers: the top 1% of wallets, mostly bots, took 80%+ of all profits. Retail lost $131M net. Same predictions - better data. What that data shows: pull the depth on a BTC 5-minute market and watch the last minute. Resting bids at T-60 sit around $1,210. At T-10, $240. At T-3, $90. 95% of the liquidity you think you can hit vanishes before resolution. A $500 buy at T-30 eats ~4.2¢ of slippage - half the edge, gone. One tested pattern: when depth leans 65/35 while price sits flat, it reverts within 60s 73% of the time. Median lag from depth to price: 11 seconds. 312 signals in 30 days. The depth wasn't lagging. It was waiting. That's the whole game here - not calling the candle, but seeing depth shift before price does. This wallet did exactly that. Every level, every 300ms, 13,000+ resolved markets, free to replay.

This 24 year old man stands at the door of the business he works at to let in customers and to keep ICE out! This shouldn’t have to be happening especially when everyone that works there is a U.S citizen,but he’s also protecting his customers! 👇👇

This is a really great video 1) She actually works in investment banking in a front office role, and therefore her nights are an actual representation of the job 2) This shows that even with long hours, you can go to sleep at 1AM and have a perfectly sustainable lifestyle 3) If you are tired of turning comments after 10pm, the buy-side is actually better

YO ADRIAN! I DID IT! Update on my TMNT SNES port. This is the most extensive OAM overhaul I've ever done with a port, and I'm damn proud of myself! Lot of reverse engineering with the OG OAM engine, and I was finally able to incorporate a new method of writing to the buffer. This game does some heavy ADC/TAX for OAM buffer rotation to try to work around the sprite flicker. But that ADC/TAX rotation was complicating things for me when I was trying to incorporate a 16-bit index engine. What is also tricky, is that this game uses 8x16 sprites, and what is special on the NES, its hardware creates the bottom 8x8 sprite tile, without the need of the OAM to have it present. You can't do that on the SNES, you have to create that 2nd 8x8 sprite tile within code. The reason this is such a big deal, is before with 8x16 titles i've worked on, I would first simply copy the games original oam buffer to my snes buffer, but that addded alot of extra cpu time, this is present in my Legend of Zelda SNES port. Later ports I've done, I don't do that anymore, I modify the games original storage of OAM values, and send them directly to my custom snes OAM buffer, eliminating extra cpu cycles. So what's the big deal? My method of doing 8x16 sprites, is using my first 256 byte oam buffer for the top 8x8 tile, and my second 256 byte oam buffer for the bottom 8x8 tile. The issue I was having, was errors with sprite priority when sprites overlap each other. I noticed this right away during the dam sequence where the turtles have to disarm the bombs. Here is a before and after my port. Now I can finally move on with the port! 🙂

Most C Programmers don't have a clue as to how the CPU works. Here is a lecture from my course on the C Language that introduces how to visualise the CPU as a C (or general software) Programmer.... More Details are at: Being able to model the behaviour of CPU provides a solid base to reason about your code. The summary is - - The CPU is a state machine which maintains it's states in registers. - It has busses to memory for requesting data/instruction read/writes. - Interrupts to attend to events. I discuss this and more in my course on the C Language.
