@dannypostma I've been working with aws and gcloud with my enterprise clients for many years. The common dogma is that storage is cheap so there is no point of cost optimisation. This just shows how bluntly wrong this thinking is. Cloudflare FTW!

Do you work with #helm in monorepo setup? This is what you can do to "dry" your setup

@NewhamLondon I guess that's why. 0 emission is still emission according to this table. Maybe just change the name from "emission charges" to just "charges".

@NewhamLondon How is it that my zero-emission car increases my parking permit because of emissions?

@robdix My local GP has 8am game sadly. I’ve switched to eMed for virtual appointments but sometimes you need to wait days. GP access seems a tad broken currently

gpt-4o blows gpt-4-turbo out of the water.
So quick & seemingly better answer.
Also love the split-screen playground view from @OpenAI

We’ve started deploying changes to Amazon S3 to make unauthorized requests with certain error codes which were not initiated by you to be free of charge. This change covers a range of HTTP 3xx/4xx status codes. It will take a few weeks for the roll out to complete in all #AWS Regions.
For more details check out aws.amazon.com/about-aws/what…

Update: S3 engineers are working to make unauthorized requests that customers did not initiate free of charge. This change will cover a range of HTTP 3xx/4xx status codes, including all of those cited in the article. We're moving quickly and we plan to share more details this week.

NEW: S3 will no longer charge for requests resulting in HTTP errors.
The fix is rolling out today and will take a few weeks

AWS needs to stop charging for 4xx requests to s3 buckets immediately. In GitHub here are 63k references to us-east-1 buckets alone. Anyone can start racking up massive bills for these users with a simple PUT request!

@nicoschriever Cloudflare. This gives you easiest setup web proxy as most likely next step

@virattt I didn’t know query routing could be that simple. Thanks for sharing the code.
English

Financial assistant query routing🚦
I implemented 3 data sources for query routing:
• polygon api
• vector db
• google search api
Given a user query, the assistant will route query to correct data source.
Then, the assistant will use the data source.
If the query relates to stock prices, use polygon.
If the query relates to SEC filings, use vector db.
If the query relates to recent events, use google search.
All of the code for query routing and calling data sources is implemented.
I use $MSFT in my code, but you can use any ticker.
Future improvements:
• more polygon api endpoints
• more filings in vector db
• clicking into google search results

I really struggle with selling my old stuff once its no longer needed. Decided to see if I can write a small @streamlit app that will help me with it.
It supports multi file upload so it really should speedup the whole process

@david_nix 👏💯I can sign under this with both hands. After a dacade in enterprise your brain is wire for “best practices”. Those are mainly there so you can work on a huge teams. When you work alone you have to scrap 95% of what you believe is the right way. Not easy
English

Software engineers wanting to be entrepreneurs think we have an advantage.
I've built distributed systems that process billions of events in realtime which run at near 100% uptime.
These systems are so reliable, the critical incident rate is about one per quarter.
And yet, I struggle.
I'm not a successful entrepreneur yet. But I have learned one thing:
Unlearning is more important than learning.
You don't need:
- e2e tests
- CICD pipelines
- Data warehouses
- >80% unit test coverage
- To handle that edge case
- Zero downtime deployments
- AWS, Google Cloud, or Azure
- Metrics, alerting, and monitoring
"Best practices" are a liability to an entrepreneur.
Case in point:
I use a data warehouse in my project, YourNextDomain .com, and I should've used sqlite or duckdb.
I wasted weeks learning the platform. And now I'm stuck with a $70/mo bill and rising.
Your job, as an entrepreneur, is to find pain where people pay you to take it away.
Your superpower is you can build something truly unique - not some no-code CRUD app or AI wrapper.
But finding the pain is paramount. And it takes a lot of trial and error.
You can't afford "best practices" slowing you down.

@LynAldenContact Hopefully more people will have this realization. It’s enough to have your account frozen or transaction blocked just once to start looking for alternatives
