Exactly right - it's a legacy feature we keep not to break some user flows, we're looking to rebuild that pretty soon.

Some parts are actually in C, but they've all been.. containerized. I'll see myself out.

We're focused on routing (shoreside) and not navigation at the moment, so we've been able to build a custom in-house map focused on the needs of crew managers and operators. Unfortunately you're right about the rest - it&#x27

It's a mix really: all of them care about the cost savings, but the UI and the opportunity to digitize and connect different parts of the business have also been strong drivers. First-generation software has been around just long enoug

Could be! Sometimes things get stuck up there and over time weather down to something I can no longer Google or remember attribution for :)

this is awesome, will definitely be checking it out. ADS-B is definitely more popular than AIS, and I've always wondered why. Perhaps it's that airplanes evoke more wonder, and is more accessible over land than poor old ships? Do

We've been using PostGIS' internal storage mechanism for routes and tiles so far. We've attempted to build our own indexing (through quadtrees indexed similar to OSM's), but it's never crossed the performance we get

We've been using a mutated blend of our own patterns with the ones you mentioned, but you're 100% spot on. The reason we have a product today with 100% uptime and reasonable tech debt is that we front-loaded the cost of data by ma

The most challenging aspect for us has been getting integrations with client software done and out of the way. Unlike other industries, the existing software around crew, reporting and planning are often in-house and in some disrepair, from

Thanks! Nick can chime in here once he's up - I'm the night owl (we're on SGT) and he's up in a few hours. But the way I see it, most of the problems around piracy are systemic. I'll skip going into too much detail,

I meant we're not as good at simplifying the narrative, as we hope Greywing is at simplifying the task of vessel operations :) We don't currently use any AI - we're yet to exhaust deterministic knowledge-based algorithms, but

Completely agreed - and it's something we've had to work very hard at. A rule of thumb that's worked for us is that the more information you show, the more tolerant your users are. However, that's also directly in opposi

Thanks! It's a mixture of all of these things, to be honest. We had visibility into and in the industry due to our work with maritime security, as well as the benefit of being in an uncontested space (vessel operations intelligence) wh

None directly, but we believe improving crew well-being and providing more assistance to ensure vessels operate smoothly will have a long-term impact. Ships can only function as well as the people on-board, but it's an often overlooked

Thanks! Our process has been client-driven from day one: we've got a good amount of technical and maritime expertise on our side, but it pales in comparison to the mountain of operational knowledge that our users have. What this means

We take all the information you (a ship manager) have about a vessel (route, plans, crew composition), with all the information externally available (piracy, flights, fuel costs), and tell you where to route your vessel and what the best ch

I didn't know that either until I joined maritime! They are still very much a thing, and Nick could tell you stories forever - in some cases it's a well oiled machine, where the pirates know the insurance negotiators and vice vers

Thanks! Interesting that you ask that - we have very little (if any) overlap with Flexport. They focus on the cargo and the freight, and we focus on operations. We've definitely helped operate some of their vessels in the past! There i

I agree. I forget who I'm quoting (and butchering), but it's become one of my favorite aphorisms that "Data is everything. Once you have the right data structures and relationships, the algorithms are apparent."

Agreed, but entirely dependent on context. Most writing on the web (including most of my work) is designed for reach, for all of the narcissistic reasons like retweets and shares, but also the reason that we live in a more democratic world

Margin Call was exactly what I was thinking as I read this. Underappreciated movie - definitely worth a watch for a more realistic take on 2008nthan The Big Short.

Agree with most of the comments, but it's worth mentioning that you will never get those things for cheap. The reason most of the things you buy are cheap is due to economies of scale - you want something a lot of people want. Want a b

Thanks! Really appreciated. I've gotten the hang of SVGs, is MBostock's blog still the best place to start with D3?

by hrishi 6y ago
Could you elaborate on the best way to get started with this specifically? Any articles/tutorials you'd recommend? I've been meaning to forever but both svgs and d3 are complex enough I'm not sure where to start.

It's amazing how many comments suggest training a neutral net for prediction. Additional fitting through elo ratings I believe are suggested, as is dynamic tuning. To me, having played games with rollback, this takes away one of the ke

The problem (and the solution, in some cases) is the middlemen. You need to use a well-defined, pre-agreed interface (ERC-20 for tokens, and ERC-721 for NFTs I believe) so middlemen like OpenSea can understand and transact your NFT on their

I think the value of NFTs purely based on "ownership" will not last very long. Yes it's cool, but most of these are already on the way to becoming almost purely speculative instruments. Some - like punks and hashmasks among o

It is indeed bitchy! I'd say simply having different scaling needs may not suffice to isolate services, especially if all the other parameters I mentioned stay the same. Even so, some cases for needing to isolate purely based on scalin

A good primitive rule of thumb that's worked for us is to fork services when: a. They're performing an action fundamentally different to the the block they originate from (one service may respond to user driven actions, another ma
