One of the big promises of software is composability. You can build rich, powerful experiences out of basic building blocks.

APIs add new things to the toolbox. For example: Treasury, which lets an app/platform store, move, and track a business’

I've been a small business owner and can talk at length about SMB banking, and will later, but let's put on the software developer hat right now.

Lots of software talks about money, keeps records about money, does calculations about money, but can't *touch* money.

This is extremely frustrating when you're building SaaS apps for businesses, because you have total control over your UX right until your app needs to touch money... at which point all data about it lives in a silo you can't access.

So you generally push work to the operator.

For example, suppose you’re writing a business-in-a-box system for electricians, including an invoicing feature.

You need to be able to read bank transactions to reconcile. You probably can't. The owner can. So you ask the owner to do mind-numbing work a computer does better.

It sure would be great if your business customers had bank accounts you could actually introspect and operate on their behalves! You could just get the list of incoming payments and match against the invoices.

There is some software to write but it is not rocket science.

I've gotten a few questions about Aurora Serverless v2 preview, so here's what I've learnt so far. Please feel free to chime in if I've missed anything important or got any of the facts wrong.

Alright, here goes the 🧵...

Q: does it replace the existing Aurora Serverless offering?
A: no, it lives side-by-side with the existing Aurora Serverless, which will still be available to you as "v1".

Q: Aurora Serverless v1 takes a few seconds to scale up, that's too much for our use case where we get a lot of spikes. Is that the same with v2?
A: no, v2 scales up in milliseconds, during preview the max ACU is only 32 though

Q: is the cold start for Aurora Serverless v2 still a few seconds?
A: yes, unfortunately...
Q: so if you want to avoid cold starts, what's the minimum ACU you have to run?
A: minimum ACU with v2 is 0.5

Q: does v2 still scale up in double increments, e.g. 4 ACU -> 8 ACU?
A: no, it scales up in increments of 0.5 ACUs, so it's a much tighter fit for your workload, so you'll waste less money on over-provisioned ACUs

It's incredibly hard to become a customer of @Telstra so you can give them money. They absolutely despise money, and do everything in their power to erect as many obstacles as possible in the way of a normal person establishing a billing relationship with them.

First: "I'd like to buy a 4G WiFi hotspot please."
"Umm, we don't have any. Maybe try K-Mart."

Are you serious? You can't sell me a mobile broadband service, and you'd prefer me to go to a department store. Okay...

So I go to the department store, and they have the same Telstra product $20 cheaper than Telstra does.

Go to activate it. Error message, SIM serial number has already been activated. Well goddamn.

So, back to the @Telstra shop. "Yes, I know I can return the whole thing, but all I want is a $2 SIM to get started. Can you just sell me one of those?"

No. They don't have any. Zero SIMs in the store.

ARE YOU KIDDING ME? WHAT OTHER PURPOSE DOES A TELSTRA SHOP HAVE?

Their first suggestion was to buy one from @AusPost, but they take 24 hours to activate their prepaid SIMs. Maybe try Woolies?
