code-is-codeon Nvidia predicts AI models 1,000,000X more powerful than ChatGPT within 10 years

Training in parallel on more then one GPU is pretty hard. Distributing the training over many random computers and adding at least some kind of validation, seems to kill the performance. So it would always be easier to rend cloud GPUs.

code-is-codeon Local-First Web Development

Not true. Most RxDB users use the dexie.js storage which is for free: https://rxdb.info/rx-storage-dexie.html Also you should compare it to the alternatives like firestore or AWS datastore which are not even open source partially and cannot even be used with a self-hosted server.

code-is-codeon Downsides of Offline First

Firebase works until you want a different conflict resolution then last-write-wins. It is also only offline first if the user is authenticated. Otherwise you need a connection to the servers before using the local state.

code-is-codeon Web Applications from the Future: A Database in the Browser

You should have a look at RxDB which does exactly what you have described. Also notice that neither firebase nor supabase is really offline-first.

code-is-codeon Ask HN: How do you organize yourself ?

I made a whatsapp group where I am the sole participant. This makes it easy to work on my "todo-list" on all devices synchronized.

I had to close 5 popups just to read the first line of text.

code-is-codeon Is WebAssembly magic performance pixie dust?

code-is-codeon Create an anonymous link that will hide the HTTP Referer header

No, just dangerous for your users.

code-is-codeon Create an anonymous link that will hide the HTTP Referer header

This is so dangerous to use. There have been hundrets of these sites in the past. As soon as they have enough traffic they silently redirect or change affiliate ids etc. Do not use them, the rel=noreferer is good enough.

I think the time has come where a PWA does it for most kind of projects.

code-is-codeon Ask HN: What companies are you excited about?

I am waiting for the time when every "normal" website is so censored and shitty that the average joe is using tor. Then we can create a truly free internet and the cycle starts again. Seems like I have to wait just a few more years.

Also we can predict the short shift to altcoins again before the bubble explodes.

code-is-codeon We’re Google Workers, and We Are Forming a Union

No this is not a good thing. Binding workers right to political views is dangerous and other countries show that unions can work without any party propaganda.

code-is-codeon Ask HN: Why aren't one-time sign in links more popular for authentication?

This. Same happens with the sms verifcation in microsoft teams. On older devices switching to the sms app will restart the teams authentication process. So you have no chance in every typing the correct 2 factor sms key.

code-is-codeon Ask HN: I wish I knew before I launched my project

code-is-codeon Ask HN: What were the things you did that made the biggest impact at your work?

Doing API-first.

Start with defining the swagger.json Then generate:

- frontend-typings

- frontend request services

- backend routes and DTOs

- database fields

- use angular-jsonform for forms

- use the swagger for frontend validation

- use the swagger for backend validation

- use the swagger to discuss api changes with the client

This saves half of developing time and prevents 90% of your bugs

code-is-codeon Replicache: Easy Offline-First for Existing Applications

RxDB maker here.

You can do conflict-resolution by subscribing to the changeFeed and when multiple versions with the same revision-height exist, you create a new version with a 'merged' document. Depending on your dataset this can be tricky and painful.

RxDB can only be used with javascript and will likely ever be.
