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:

https://toanoa.com/

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.

Hilarious analogy

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)

https://toanoa.com/

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.

Slightly related but how does WAL-G stack up as far as backup/restoration options go for Postgres? https://github.com/wal-g/wal-g

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.

Would you be interested in sharing the code? I'm working a similar project and wouldn't mind exploring your code base.

Unfortunately its closed source at the moment but happy to discuss the problem space. E-mail in bio.

> I built it initially as a favor

That's a hell of a favor. Is this something you built by yourself or were you part of a larger team?

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.

Sounds very interesting. I'd love to take a look if open source?

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 good news is that if your car has a 3G embedded modem, it probably doesn't have any networks to connect to anymore.

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)

TLDR: OP is using geography as a dog whistle.

I have a problem when governments decide it is perfectly alright to interfere in how citizens should conduct their religion or even what religion they should follow, which I believe is a deeply personal affair. I have a problem when there is no separation of state and religion, and when said governments regularly criminalise (up to capital punishment) things like apostasy and blasphemy, which are decidedly mediaeval attitudes.

It so happens that the large majority of these governments are in Muslim-majority countries, where Islam is the 'state religion' (I have a problem with 'state religions' too). Therefore, a reasonable conclusion: it is that particular religion that demands these of its adherents (and worse, non-adherents), and therefore, I mistrust it.

> a number of North African countries as well

For the record, I have little problem with Tunisia.

> criminalise (up to capital punishment) things like apostasy and blasphemy, which are decidedly mediaeval attitudes.

Another HN post today motivated me to look up the history of British blasphemy law and it turns out it was not medieval. Criminal blasphemy laws appeared right at the end of the Middle Ages (at least in England and Wales) so are mostly modern. Before that the punishment for blasphemy was excommunication.

Enough said. This isn’t an informed opinion

"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.

GP knows there are large numbers of oppressed people living in Dubai and concludes there must be large slums.

That article says he was trying to flee to the Dominican Republic, not the UAE.

The article is from October - in the meantime it turned out he actually fled to UAE. The Polish government tried to extradite him but failed. There are many sources on that, unfortunately in Polish only.
