I am building an Excel extension that lets me use LLMs in formulas. For example, I can write =PROMPT(A1:E1, "Extract keywords") in a cell to extract keywords from a row and drag the cell to apply the prompt to many other rows. I find this useful when I want to use AI for repetitive tasks that would normally require copy-pasting data in and out of a chat window many times. I actually built it for my girlfriend who was…

#553My first job was in a FinTech and the way production access was managed scared me. This is my approach at streamlining the process. Basically a PR review flow for SQL queries, enforcing the 4-eyes principle so you never accidentally can do a Delete * form users, forgetting the where clause.

#554In the best case, the developers of e-commerce website create unit-, integration-, and functional tests to make sure, they do not break existing functionality.
But a website is not only code. Its also data and configuration.
Since these types of configuration (e.g. prices, legal texts, bonusses) can change quite often and can get quite complex from the business perspective, it does not make sense to have developers create automatically executable tests to make sure, the website is configured as it should be.
And its often not the developers who change the configuration. Maybe its a product manager, a marketeer or the ceo.
These people often do not know if they configured something correctly. In additiom, they often don't get any notification, if an process, that is important for them, breaks due to a misconfiguration or some bug in the code (not every code base has a test coverage of 100%).
So, I am creating a No-Code Black Box E2E Monitoring Tool, that the process owners/configurators can use to regularly check, if everything is working fine.

#555I'm very proud of the way the architecture turned out - with most notably a components-driven architecture [1].
There's just a major performance roadblock in posts with many comments that I should be able to clear with some more multithreading. Then I just need to make it available in brew and other distribution solutions.

#556Hey guys! We're engineers/designers from France, and we've built the Ultimate DIY Battery that you can repair and refill! It works with 90% of the bikes/motor brands on the market, so I assumed that some people here might be interested, if they got a non-functional batteries but they still want to use their e-bike? We believe that everybody should have control about stuff they own, and we should fight against planned…
That being said, I am a bit skeptical about your claims to be fireproof. Did you try to start a battery fire inside your enclosure? Aluminum melts at about 600C, while lithium burns much hotter than that.
