I've shared this one before but I built a logistics management system to power deliveries for a business I founded years back and I've continued to refine it since:
Since the initial MVP, it's done close to 100k orders and I've added new functionality like:
- Intelligent order batching & route optimization that can interleave tasks across orders in such a way that they still have the best chance possible of completion within their delivery windows
- Further refined the mobile tracking logic in our driver app to improve the quality/frequency of position updates while continuing to be as efficient as possible on battery
- Numerous backend/DB optimizations such that average response times are in the tens of ms at the current volumes it's handling.
It's not open source but if you have an interesting use case and are curious about it, feel free to reach out.
Built a last-mile delivery/logistics management system to power deliveries for on-demand/hyperlocal services and launched it last year (mentioned it in another one of these threads last year)
To date it's handled more than 70k orders, ingested nearly 10m telemetry records, has been extremely reliable, is almost entirely self-contained (including the routing stack so no expensive mapping dependencies) and is very efficient on system resources.
It handles everything from real-time driver tracking, public order tracking links, finding suitable drivers for orders, batch push notifications for automatic order assignment, etc.
I guess it's not ENTIRELY a favor since I founded that company but stepped away a few years back and always felt a bit guilty ever since. They certainly weren't expecting me to build it though.
I built it all myself (including the integration with our ordering platform) It was sort of my white whale project that I've always wanted to do but didn't have the chops/time.
The advancements in AI-assisted coding encouraged me to give it a shot though and the results turned out great. It was a heavily supervised vibe-coding project that turned into a production-ready system.
Just built a last-mile logistics management solution to replace a SaaS solution for a delivery company I used to be involved with.
Handles everything from real-time driver tracking, public order tracking links, finding suitable drivers for orders, batch push notifications for automatic order assignment, etc.
Backend: Feathers.JS, Postgres + TimescaleDB & PostGIS, BullMQ, Valhalla (for multi-stop route optimization although most of our deliveries are on-demand)
Frontend: SvelteKit
Mobile App (Android only for now): React Native/Expo, Zustand, Expo push notifications, and two custom native modules for secure token storage and efficient real-time GPS tracking. The tracking was probably the toughest to get right to find the best balance between battery/data efficiency and more frequent updates.
Been testing it for a couple weeks and as of last week, that company moved their operations over to it with 50+ drivers and thousands of orders processed through it so far (in a country with pretty unreliable connectivity/infrastructure).
I built it initially as a favor but open to other applications for it.
Great link! Might have found a bug in Chrome with it though :)
I was curious to see more about the internals so I opened up Chrome Devtools and as soon as I clicked on the "Application" tab, it crashes Chrome and did it every time.
The implication of using "632 CE" appears to be a reference to the proliferation of Islam after the death of Muhammad (I didn't know this until I Googled)
So if that individuals distrust towards the Arabian peninsula begins in the exact year Islam began to spread, it wouldn't be a stretch to assume that OP is an Islamaphobe (and it would include a number of North African countries as well)
"I went to <insert any major city here> and there's tall buildings and slums beyond"
Even Vienna has slum-like areas, every major city does. Not sure how that's a knock against Dubai. I'm not even sure what slums you saw in Dubai, Having lived there for a few years there's definitely low income housing in certain parts but I'd struggle to call them slums.
I just used Pitivi recently to cut something and quite liked its straightforwardness.
The only thing I don't like is the lack of preview monitor so I can work with raw clips before bringing them into the timeline but for quick cuts, it's a great tool.
I had some of these issues with the 5.17.x kernels but once I switched to Fedora 36 and 5.18.x, and updated the BIOS, the situation improved dramatically and sleep was fixed.
