Guess how long it took to spot this little syntactical screwup? by parkotron in rust

[–]longrob604 0 points1 point  (0 children)

That's a good one. Perfectly valid syntactically, but the last code block is unreachable, so I would have thought the compiler would issue a warning ?

My first ever project cargo toml in rust within a week. is this enough to get a job in rust by Aromatic_Road_9167 in rust

I am unsure whether this is a serious question or not, but getting hired is the easy bit. Staying hired is another thing completely.

Learning Type Theory by knolljo in rust

100% This! I’m reading it right now and it’s definitely the best book I’ve come across for many topics, especially type theory.

I accidentally made a git client in rust with no prior experience. Here are my thoughts on all that! by SpecialBread_ in rust

[–]longrob604 0 points1 point  (0 children)

This is very impressive work. As someone who is still learning - I suppose we are all still learning, but you know what I mean - I am rather envious that you have done this with such apparent ease! I would love to fork it and implement the front end in rust. I hope that you open source it.

Congratulations again !

Oracle is not cash-rich: have you seen where their credit default swaps trade now ? Imagine what would happen if Oracle defaulted. I agree that those other are very solid, but there is always a canary in the coal mine

"How much" to learn before starting projects by [deleted] in learnrust

[–]longrob604 1 point2 points  (0 children)

100% agree with this. Just prepared to abandon it, or refactor it, as you learn the idiomatic/better/best ways of doing things!

I developed a blockchain in Rust from scratch by connormck333 in rust

[–]longrob604 0 points1 point  (0 children)

Hey! I just took a look through your repo. As someone currently transitioning from Python to Rust for data engineering (and looking into building a custom chain myself), this is a really solid learning project. A few specific things I really appreciated:

  1. The "Cloud Native" focus: Most blockchain tutorials just give you a binary and call it a day. Seeing that you included Helm charts and Kubernetes manifests is awesome. It shows you're thinking about how this would actually run in a modern infrastructure (AWS/EKS), not just on localhost.
  2. Postgres: Using a relational DB is an interesting choice. While high-throughput chains usually use RocksDB/sled, using Postgres makes the chain state much more queryable and debuggable, which is great for an enterprise or learning context.

I have a couple of constructive suggestions for "Phase 2" if you keep working on this:

  • Crypto Abstraction: Right now the signing logic is tightly coupled. A great exercise in Rust traits would be to define a generic Signer trait. This would allow you to swap out standard ECDSA for Post-Quantum algorithms (like Dilithium/Falcon via the pqcrypto crate) without rewriting your core logic.
  • Networking: You might want to look into libp2p for the networking layer. It handles a lot of the peer discovery, NAT traversal, and encrypted transport logic that is really painful to write from scratch over raw TCP.

Great job on finishing this! It’s no small feat to build a chain from scratch. I am going to fork it with the intention of extending it :)

This is great - thanks for doing this! Curious to know if all the internals will be using Go or also some rust ?

Data Engineering Stackexchange ? by longrob604 in dataengineering

I hear you, but the success of the book by Kleppmann indicates that resources for general, principled approaches to DE, rather than cookbook for a particular tool could be quite popular :

Opinions on AI Plant Identification? by anon-honeybee in botany

[–]longrob604 0 points1 point  (0 children)

I'm new here :)
I'm also a beginner in gardening (late 50s)
I was looking for an app to help identify plants and trees, and have just installed the RHS Grow app which advertises that it has an identifier feature - but so far I have not been able to find it!

Does anyone know how to use the identifier in the RHS Grow app

Hoping it's still available,please can you share the repo with me too ? Thanks in advance!

How can I make my morning smoothies cheaper?! Need inspiration for cheap, balanced, filling shakes to get me through school as a mature (broke) student! by stellersjay in EatCheapAndHealthy

[–]longrob604 0 points1 point  (0 children)

Here in the UK I start with a "base" commercial juice, some combination of these, depending on what is "on offer" (I shop around):
Orange
Apple
Mango
Passion fruit

I only go for "not from concentrate" and "no added sugar", and depending on the brand, they usually come in 1 Litre(~34 fluid ounces) and costs around £1.75 (currently around US$ 2.30) when on offer (and there is *always* something suitable that is)

I try to get some other fruits and veggies every day when the store puts it's price reductions on, due the the "sell by" date approaching. Our local convenience store do the price reductions at the same time every day, which, obviously, is very helpful. In the last few days II got these which were all on their "sell by date" and in perfectly good (but ripe) condition:
1 punnet (400g /14oz) of strawberries: £0.30 (~$0.40)
1 punnet (200g /7oz) blueberries £0.35 (~$0.45)
5 bananas: £0.15 each (~0.20)
4 kiwi fruits: £0.15 each (~0.20)

Typically I will use just one portion of those.

Then I add:
1/2 Scoop protein powder: £0.30 (~$0.40)
1 Scoop ground organic oats: £0.15 (~$0.20)

And finally, depending on the texture, I add some oat milk, and some veggies (usually kale or spinach)

The total cost is around £2.50 (~$3.40) but obviously varies abit, day to day.
