Ask HN: What problem can I help you with?

How can I refactor a monolithic codebase when every change breaks everything?

I'm not sure what you're looking for, but a fun problem I ran into one day (one that I solved, but ultimately we went a different route) is to find an existing key in a js object, and insert a new key/value js object after that key.

For example:

const userdata = [ { name: "Emma", age: 21, hobby: { reading: true, gaming: false, sport: "tennis" }, class: ["Java", "Go", "Nginx"] }, { name: "John", age: 22, hobby: { reading: true, gaming: false, sport: "football" }, class: ["JavaScript", "HTML", "CSS"] }, ]

const newdata = { knitting: true }

And then, the task is to make a utility function to find "name: John", then "hobby" and append newdata in the "hobby"object. Try to apply immutability. Try to do without the overhead of JSON string conversion.

Employment. I'm old enough to wonder if it's age discrimination. I've got a messed up work history that it probably isn't, but I never had problems finding work until after I was 35 (I'm 47 now). I've done enough crazy things that I've added additional obstacles to normal sane employment. But, I'd like a stable job, one that pays well enough to import my wife, in the UK/Ireland or US based working remote (EU would also be great but brexit took that away from me). I've been working short term contracts that are okay and I live in a cheap place (I am living in Turkey), but my last contact just ended.

My last job was game dev but I'd rather do things I previously was doing, Python/perl/C/Matlab scientific computing.

I have an open-source web testing framework that I've been working and I'm preparing to launch. I you're interested, I'd love any feedback on using it or where to improve the documentation.

I need help building Wixsharp deployments of my note-taking app that hasn't seen the light of day, and/or otherwise migrating the code to Github to allow others to build from source.

In general I need help launching.

You are software developer so have you created any hobby product? If yes, how do you start marketing of it?
