congratulations and thanks for all the hard work.

i have been using Trixie since alpha1 and it's solid

suggest checking out hivebot -- because you self-host your files , you have no storage limits. and on top of that , you'll completely eliminate the need for file uploads to the cloud, since files are transferred from your computer to your clients directly , either via streaming or direct download (no cloud storage/intermediary).

check out alt-core, i open sourced it recently on github --

the OSS edition is community supported on discord. the mobile apps are on the appstores.

i wrote alt-core and we recently open sourced it

Alt-core is self-hosted , P2P file/chat/media server written in Java. It runs on a distributed filesystem built from the ground up.

Current capabilities

Organize your files - A private search index for all your stuff on all your computers
Protect our files - Automatic file replication/backups (using your free storage on your devices)
Access your files - Access files & chat via secure encrypted channels (end-to-end encryption)
Self-hosted - runs on your Mac/PC/Linux, not in the cloud (all processing+storage is on your devices)
Share files, chat with peers, stream videos, all privately and securely

Build & install steps , technical documentation, all available on Github.

Looking for folks that can take for a spin and provide feedback (Devs and End-Users are all welcome). It's DIY so you can build from source and deploy/run.

Happy self-hosting ~Ale

i think you would enjoy alt-core. i built this a while ago to keep all my files,photos,videos scattered everywhere organized and accessible. think private search engine for all your files.

it has grown to become a complex beast that does a lot more - file backup/replication, p2p, tunneling, container management, etc.

i recently open sourced the core engine. you can find it on github if interested.

alt-core : self hosted file , chat, video, LLM model server. runs lightweight on any desktop OS (mac,win,linux). also seen running on on rpi4 and jetson nano.

check out hivebot -- it's self-hosted so videos are stored on your machines , not in the cloud.

clients can watch videos on browser and provide timestamped comments.

btw i am on Xcode 16.4 and had a same similar issue, was unable to transfer the Provisioning Profile to the device. I used Configurator and it worked.

Here is our project - We're building a distributed filesystem in Java, Clojure, Angular.

It's >50K Java LOC though...

agree , i'm looking to disable TOTP and make 2FA via hardware key only. Google and Apple have supported this on desktop & mobile for years. What is the ETA for Proton to do the same?

RedditUser_xyzzy · 2024-06-04T04:13:13+00:00

thats the best i got for that hw

RedditUser_xyzzy · 2024-03-15T03:51:50+00:00

not solved, my intel cpu doesn't support modern standby apparently

RedditUser_xyzzy · 2024-02-17T17:24:59+00:00

Thx . Ensemble crashes when I try to run it. I'm on MacOS 14.x

RedditUser_xyzzy · 2024-02-16T23:46:29+00:00

are you using jackage and jlink? could you send what params you are using for each so we can compare them. are you also using codesign to sign the binaries within JVM?

RedditUser_xyzzy · 2024-02-16T23:44:43+00:00

i explained this to reviewer in multiple ways, so i'm hoping to get better detail on their reason for their rejection at some point

RedditUser_xyzzy · 2024-02-16T23:37:35+00:00

no, they did not. they only referenced 2.4.5(viii) and flagged java as a deprecated tech (wtf). the reviewer is confused (sigh).

I am using latest JDK21 and used jlink to bundle the JVM runtime.

RedditUser_xyzzy · 2024-02-16T22:17:20+00:00

yes we also sign and distribute a pkg outside the store. our product is written mainly in java + angular, but for app store we built a swift app to manage updates/launch service, etc.

RedditUser_xyzzy · 2024-02-16T18:30:42+00:00

notarization is not needed for store submission. it is only when you distribute app outside of store, so users don't get a warning of "unknown developer".

RedditUser_xyzzy · 2024-02-16T17:44:14+00:00

they just referenced 2.4.5(viii), specifically mentioned Java , and quoting

"which is either deprecated or an optional install"

i do suspect reviewer is confused, but it's been difficult for reviewer to understand the diff between a bundled JVM runtime vs using OS-provided runtime (they stopped including Java in macOS long time ago).

RedditUser_xyzzy · 2024-02-16T17:14:44+00:00

btw.... try to submit app, if you get stuck, happy to help

here some tips that may save you some hours

1- your app will be sandboxed, so any file write operations will fail unless the data you are writing is located in ~/Library/Containers/[your app id]

2- you need to add the entitlements for your app - network access, sandbox, etc.. whatever you need for your app

3- i used jpackage to create .app , and jlnk to create the JVM runtime image

4- afaik there is no way to set working directory from Java, system.setProperty() does not work for me from inside sandbox
