Creator here. I built ChartGPU because I kept hitting the same wall: charting libraries that claim to be "fast" but choke past 100K data points. The core insight: Canvas2D is fundamentally CPU-bound. Even WebGL chart libraries still do most computation on the CPU. So I moved everything to the GPU via WebGPU: - LTTB downsampling runs as a compute shader - Hit-testing for tooltips/hover is GPU-accelerated - Rendering uses instanced draws (one draw call per series) The result: 1M points at 60fps with smooth zoom/pan. Live demo:…

undercutf1 is a F1 live timing app, built as a TUI. It contains traditional timing pages like a Driver Tracker, Timing Tower, Race Control, along with some more detailed analysis like lap and gap history, so that you can see strategies unfolding. I started to build undercutf1 almost two years ago, after becoming increasingly frustrated with the TV direction and lack of detailed information coming out of the live feed. Overtakes were often missed and strategies were often ill-explained or missed. I discovered that F1 live timing data is available over a simple SignalR stream, so I set out…

I'm working on a GPS track visualizer for quite some time. It shines in hilly and mountaineous terrain (where a 3D view makes more sense), but it also offers quite a lot of Strava-like features (statistics etc.). You can upload your GPX and FIT files manually, or sync directly with Garmin, Coros and Polar. See https://cubetrek.com for the live app and check out some examples there. It's free and opens source. Also, anyone who likes to work with 3D visualizations (especially Babylon.js), let me know if you like to help polish this thing further.

Instead of playing video and trying to display timing information next to it, how about we build a simulation based on timing data and become able to determine the state of the race at any given point in time based on the few 'radar blips' of sector loop passes we have? This is that. It takes the video and timing material of a 24h race (The IMSA Weathertech Sportscar Championship ROLEX24 at Daytona 2024) - 4 videos hosted on YouTube and a big CSV of laptimes and reimagines how a race replay might look like. It comes with a few non-standard visualizations, and a lot of possibilities for…

The standard GPU utilization metric reported by nvidia-smi, nvtop, Weights & Biases, Amazon CloudWatch, Google Cloud Monitoring, and Azure Monitor is highly misleading. It reports the fraction of time that any kernel is running on the GPU, which means a GPU can report 100% utilization even if only a small portion of its compute capacity is actually being used. In practice, we've seen workloads with ~1–10% real compute throughput while dashboards show 100%. This becomes a problem when teams rely on that metric for capacity planning or optimization decisions, it can make underutilized systems…

Hi I'm Dan from Elodin, making an open source real-time capable flight software simulation. For AI Grand Prix contestants, the wait for the Round 1 virtual qualifier simulation has been grueling. If you’re competing, check out our simulation harness to tide you over, built to match the published competition constraints and message format. It runs against real Betaflight, which we learned requires at least 1000 sensor samples per second to run real-time correctly. The competition warranted introducing a new feature to generate the camera sensor directly in the simulation loop. Typically…

Hey everyone! I'm a huge F1 fan and got tired of juggling multiple tabs and apps during race weekends, so I built F1 COSMOS. What it does: - Live timing: Real-time data updates in milliseconds - sector times, telemetry, team radio, you name it. No more refreshing pages or waiting for delayed updates. - Replay feature: Missed qualifying or fell asleep during practice? You can replay the live timing from any past session. Pretty handy when you're in a bad timezone. - Proper data visualization: I went beyond just showing lap times. There's race analysis with telemetry data, championship…
