Your comment is right above someone saying RJ-45 may be the worst connector! That’s just the internet I guess. I think both opinions are right. If you’re a professional working in the field, RJ-45/8P8C is awesome because you can do lar

You’re absolutely right and here’s an open source self-hosted project for MBTiles: https://github.com/akhenakh/kvtiles More info from the author here: https://blog.nobugware.com/post/2019/self

Will this be available for the open-source/self-hosted version? Would be awesome if this makes it there and we can self-host Timescale within AWS with S3 backing the storage of older data. I use Timescale for internal analytics tools -

Nice! Loved driving around and trying to break the physics. At first I was disappointed you couldn't leave the road until I found you just needed to use more speed + boost. After that I spent all the time driving off-road. I drove back

Outer Wilds. The best sci-fi exploration game I’ve ever played. A very beautiful & profound experience that leaves you reflecting on life. If anyone sees this and plays the game, don’t read any reviews or information online! Go in compl

Do you have a particular investment thesis/focus? I think many early-stage startups are hesitant to take investment vs. bootstrapping unless that investment also comes with some significant domain experience, scaling advice, connection

Linking to the primary source, Joe Barnard’s YouTube channel, BPSspace: https://m.youtube.com/watch?v=SH3lR2GLgT0 . He’s got many videos on this. Would recommend, it’s been very cool to follow his progress over the years.

Spotify won’t even let you view an artist’s songs in order, which frustrates me because I like to listen to entire discographies in order while working. I spent one weekend building a free tool to generate chronological playlists for an art

Related, check out raylib, the rendering/game engine made by the same author! I’ve used Raylib and raygui on a few RPi based projects and recommend it. It’s a really simple, intuitive way to get an OpenGL-based UI running. Good alterna

I’ve been fascinated with wooden boat-building for most of my software career, and that interest has driven me towards the marine space. It’s cool to read of other people who have a cross of software/computer skills and woodworking. I

Big fan of using DigitalOcean droplets instead of AWS for hosting simple backend APIs. A few perks: - Fixed pricing, very predictable billing - No CPU throttling vs. EC2 instances - Bandwidth included in the cost of the droplet I've bu

It's already a reality -- See https://www.saildrone.com/technology/vehicles . A few companies building serious fleets for ocean data collection.

I clicked on the site just to check it out and ended up spending 15 minutes on your demo puzzle... well played. Awesome job on all the user interactions. The dragging controls are pretty intuitive, it always did what I expected, and it&#x27

As far as I know, you can seamlessly join Timescale tables with normal Postgres tables in a query. Timescale is activated on a per-table basis.

I think you are both agreeing -- He's saying that what's "bogus" is the idea that the market is perfectly efficient and there are no opportunities.

Okay, so I've looked more into the stats based on their marketing material, and I just don't see how the math works out... They're claiming a 200kWh battery which seems a bit high for the size of the boat. An equivalent batte

Absolutely agree, couldn't have said it better myself. It's a systems engineering problem and requires rethinking of nearly every component, from the propeller design to the architecture of motors and controls. Torqeedo is an inte

The power required to plane in a boat looks a bit like a normal curve -- Power consumption scales upwards exponentially with speed until you either 1) Get going fast enough to hydroplane and reach a high efficiency regime 2) Hit the peak po

Unfortunately that's probably not going to happen anytime soon -- These electric boat startups are the real deal, but they all tend to rely on a lightweight hull to get ahead of the power density issues. Most composite boat hulls are w

Not a huge amount of information to comment on (They don't even show the fully-loaded weight of the boat which is probably the most important factor), but the focus on a lightweight hull seems like the right path and is similar to othe

For sure miniature gensets exist! They're often used on gas RC / autonomous airplanes to generate supplemental electricity. Here's one: https://www.youtube.com/watch?v=1yB49G756OI I think the answer is that t

This is great! Love seeing hardware hacks like this on HN :) Beyond just being a cool project, the detail in the README on Github is really amazing and I've bookmarked this as a great reference for releasing open-source hardware as a g

One nice use case of COBS is to clearly delimit packets being sent over a serial stream. Framing packets with zero bytes is particularly convenient for small projects because it’s easy to implement and debug. I’ve used COBS and MessagePack

Most recently I built https://www.timelineify.com/ - Spotify messes with the order of albums & singles, making it difficult to hear an artist's works in the order they were released. Timelineify generates a chronol

I reach for Spring Boot as my tool of choice for most APIs, but I feel your pain. There’s always a particular corner, the dreaded “configuration” folder, filled with a collection of random annotations, single-purpose beans, filter chain set

Definitely agree -- It's on par with the Smithsonian Air and Space Museum, and very fun to explore since it's divided between four hangers. Definitely worth a visit for anyone in that area.
