The GraphBLAS[1] is an amazing API and mathematical framework for building parallel graph algorithms using sparse matrix multiplication in the language of Linear Algebra.

There are Python and and MATLAB bindings, in fact MATLAB 2021a now uses SuiteSparse:GraphBLAS for sparse matrix multiplication (A*B) built-in.

I think Bitcoin is genuinely exciting. I know it's not exactly "under-the-radar", but a lot of the discussion on HN is unfortunately only related to the price. It's a bit of a shame, but I can understand it's hard to see through the noise sometimes.

The fact that there isn't more discussion around the cryptography, networking, etc. suggests to me that many are still unfamiliar with the power of the underlying technology.

Data Hubs. It’s queriable like a database but it doesn’t store your data - it proxies all your other databases and data lakes and stuff, and let’s you join between them. Trino is a great example.

I don't think these are really under the radar. We have Hue. We also have other apps that act as data hubs, but are slightly more constrained.

is that stuff like Presto?

I've used Presto within Hue. I'm not sure if Presto is, but I know Hue is.

Narrowband IoT data service. Very low power, low bandwidth, cheap, with increasingly great coverage. It’s like an offshoot of LTE but classified as a 5G technology for massive numbers of low power internet connected devices.

I have to admit, the idea of a run-of-the-mill security-hole-ridden IoT device being exposed to the bare internet over a wireless connection that's out of my control gives me the heebie-jeebies... and that's ignoring the possibilities for malicious use (e.g. using a low powered wireless connection for uncontrollable surveillance/data collection).

200% this. Pretty soon I'd have to live in a Faraday cage, or put all my devices in a Faraday case/jacket.

I'm not too deep into the data side of things, but this is interesting to think about.

Aren't stuff like data lakes and warehouses supposed to address the need for a centralized datastore?

Outside of perhaps an easy-to-apply interface, what benefit would a data hub provide over just streaming duplicates from all of your databases into a single data lake like Snowflake?

https://paddle.com - it's like Stripe, but their "Reseller of record" means that they handle all sales tax / VAT issues. For most SaaS businesses it seems to reduce headaches a lot.

I’m a customer, and it handles a lot of headaches for accounting. Basically you have 1 client - paddle, as far as the law is concerned. Plus has an easy checkout feature that’s inline for collecting payment info that never touches your server, no headaches securing that info.

Can you share an approximate percentage they take from a transaction for offering that service? Their pricing information seems to be hidden behind an email form.
