As an example, I have ~/Library/Android/sdk which takes 8 Go.

If I know I do not need the Android SDK, I can safely delete it.

Yes!

You can go to the folder ~/Library and then delete what you want.

To open the folder from a terminal: cd ~/Library open .

In the Finder, you can enable "Calculate all sizes" from "View options," which will calculate folder sizes to understand what to clean first.

This folder contains data from all apps; sometimes it is cache, sometimes persistent data. You will find all your previous apps taking gigabytes...

I run Arq Backup automatically in the background.

It copy Photos, iCloud files and my mails once every days to S3 with incremental backups.

It requires to have a full copy locally.

Works great!

It is not hard to configure once, with the proper folders and settings.

My name is Martin.

8+ years of professional experience. 12+ years of coding if counting my passion since childhood.

I have built and launched Weezem on 2021, and maintained it since. 100k registered users.

I have built and launched SPART on 2021 too, and maintained it until 2024. (for a client)

I have fun projects such as an OpenGL engine or completed the Turing Complete game (learn about CPU design).

I am an excellent communicator and listener, self-directed, and fast learner.

I left my previous job after 5 years with the same people. I am now looking for my next chapter.

I have been working for the past four years exclusively on react-native apps and their backend API, from bootstrap to publishing, adding new features every few months and maintaining the apps.

It was a mixed experience. When I migrated to expo two years ago, many problems were solved but not all.

But I still encounters bugs and problems with many common dependencies. It is not uncommon to have bugs on certain Android brands, with the community on github reporting the bug but waiting months for it to be fixed.

iOS is by far better and more stable than Android.

Performance is great on iOS, but less great on Android.

Our apps are animation heavy using react-native-reanimated and react-native-skia. Everything went perfect on iOS but we had to remove some animations or simplify them on Android.

Upgrading your dependencies every four months will probably break something somewhere : deep links stop working, some animations stop working, or maybe it's another dependency from the JS world. Sometime the fix is easy, other time an issue with the regression can be found on Github, other time we have no data.

Overall I'd say react-native is perfectly servicable and is easy to learn for anyone, which is a big plus. I'd recommend react-native because it is easy, have a big JS ecosystem, but I am now on the Flutter side.

We’re have a community only in France for now so the website is in french. It will be translated soon.

App: Expo, React-Native, Typescript, Apollo Client

Server: Node.js, GraphQL, TypeGraphql, Apollo Server, PostgresQL 14, Redis

Website: Webflow (great for a good website with minimal work)

Hosting: Digital Ocean (it’s cheap but I prefer GCP)

Internal tools: Retool

I had good times with Opus.

We have been capturing then encoding audio using Opus from a low-power chip (nRF52840) then sent encoded data through BLE.

Worked liked a charm! Encoding used 50% of the CPU time.

I can relate, I broke my MBP16 screen because of a camera cover. Apple repaired my mac for free without a hitch.

I like that question!

I am thankful for School 42 - Paris. In France, it is the only school which offer a (very) good software engineering training for free. Without that school, I would have made a 3-year study in a public school and my life would not have been nowhere close my today's life.

I am thankful for all the people who likes and accept me even if I may be a weird guy.

I am thankful for the enterprise where I am working since 2 years, it is a real family.

And, I am thankful to all the individuals, organizations, open-source project, initiatives, all around the world which makes a better world to live in.

Last but not least, I am thankful to all the people which are hidden, but makes our lives being worth to live in today standards.

Thank you for your help!

It actually run only on Node (but could be adapted on browser). Yes an online demo is a good idea!

I did used prettier and Xo in the past. I know I'm in the wrong but my eye are so much adapted to that C/C# style that it is way easier for me to read. For a next update/my next open-source projects, I'll think twice about it.

I have no doubt Typescript is great. I've tried use it in previous very complex projects pushing JS to limits. It had a few quircks that made it unable to use, same thing for Flow. But same thing here, I'll think about it twice next time!

Thanks!

42 Paris. Tested and approved. Really. Come to see by yourself how it is amazing. You'll be surprised.
