langtechdepot

Distribution layer for the LangTechDepot software repository, built on Syncthing (open source, no licenses, actively developed). Replaces Resilio Sync.

How it works: the repository server in California marks every catalog folder Send Only and offers all of them to each registered device. Your Syncthing client shows the offers — the pending-folder list is the subscription catalog. Accept the folders you want (software packages, training videos, ...) and they stay current on your machine automatically. Devices holding the same folders sync from each other too, so machines on one office LAN pull from their neighbour instead of from California, and everyone's upload bandwidth helps everyone else — the old btsync swarm, without the licensing.

Getting access

1. Register at https://depot.langtech.cloud. You get a token by email. It works once, on one machine — register again for a second machine.
2. Run the installer for your platform (below) and paste the token when it asks.

That's the whole handshake. The token goes over HTTPS to the registration service and never touches your Syncthing configuration, because Syncthing broadcasts device names to every peer in the cluster — a token embedded in one would be visible to every other field user.

Install

Windows — right-click client/setup-langtechdepot.ps1 and choose Run with PowerShell. It installs Syncthing through winget; on a machine without winget, download Syncthing from https://syncthing.net/downloads/ first and put syncthing.exe next to the script. (The script never downloads the executable itself — antivirus dropper heuristics flag scripts that fetch a binary and then register it for startup.)

Linux

bash client/install-langtechdepot.sh

No admin rights on either platform. The installer sets Syncthing to start automatically, registers the machine, and opens the web GUI at http://127.0.0.1:8384. Within a minute or two the folder catalog appears as offers at the top — click Add on the ones you want. Files land under ~/LangTechDepot/ (or %USERPROFILE%\LangTechDepot\).

Prefer the command line? langtechdepot-subscribe.sh / langtechdepot-subscribe.ps1 list the catalog and subscribe by folder ID.

Folders are receive-only on your machine: if something local gets edited or deleted by accident, Syncthing flags it and one click restores it. Nothing you do locally propagates to anyone else.

Sneakernet

Any synced machine holds a complete plain-files mirror of the folders it subscribes to — copy the tree to a thumbdrive and carry it. For repeatable offline updates, install Syncthing portably on the drive itself and let it sync as its own device whenever the drive visits a connected machine.

Server

See server/SETUP.md — Syncthing standup, the folder catalog, and the registration service (server/register.py) that serves the form, issues single-use tokens, admits devices, and keeps the catalog shared. Administration is register.py admin list|approve|revoke.
