Screenshot of a distributed compute fleet dashboard showing one machine named 'Nostromo' (ID 3mp2l6ul2mt2i) in an idle state with 8 cores, paired via self-attested trust hardware. Details show an Apple M1 chip with 8 cores, 8GB RAM, paired on Jul 1, 2026, and running the model mlx-community/Qwen3.5-4B-MLX-4bit. Provider status indicates the record is active and eligible for matchmaking, though live workload isn't visible in the console. Earnings panel shows 39,159 tokens for both 7-day and lifetime totals, 27 estimated jobs, and 0 tokens earned in the last 24 hours. Buttons available include 'Pause serving' and 'Unpair'.

A cream/beige Tank 300 SUV with a Chinese green license plate (浙B·F31865) parked at an EV charging station in the Netherlands, plugged in via a charging cable. The boxy retro off-roader has round headlights, gray fender flares, a roof rack, and a reflective sunshade in the windshield. It’s parked on a brick-paved lot bordered by dense green shrubs and trees, with a blue Dutch parking sign for electric vehicles visible at left.

A hand holds a small white e-ink e-reader showing its home screen. The display features a book titled “Non-Sendable First Design” by Matt Massicotte, with menu options below for “Browse Files,” “Recently Read,” “File Transfer,” and “Settings.” The battery indicator reads 97%. The device has physical buttons along the bottom. In the background are a textured couch and a round blue cushion.

**Alt text:**
Terminal window showing an `attic backup --limit 200` command in progress. A progress bar indicates 50 out of 200 files processed. Status details show 46 photos and 4 videos uploaded, transfer speed 5.2 MB/s, and 0 errors. The current file is `IMG_0993.HEIC` (1.2 MB). Elapsed time is 41 seconds.

Screenshot of a dark macOS-style terminal window showing results of a “Photos Library Scan.” The report lists 37,082 total assets, including 35,411 photos and 1,671 videos. A breakdown of file types shows mostly JPEG (26,699) and HEIC (8,640), followed by QuickTime movies (1,011), MPEG-4 (511), AVI (147), PNG (56), Olympus RAW (11), GIF (3), TIFF (2), and one 3GPP file. At the bottom it shows 489 favorites and 93 edited items.

Screenshot of a bouldering statistics screen in a climbing app. The “You” tab is open with Statistics selected. A filter row shows All gyms, Nirvana, Revolt, and Beest Boulders.

A section titled “Top 10 – Average of top 10 ascents last 2 months” lists recent climbs with grade, route name, gym, days until expiration, bonus, and points. The top entry is 6B+ “5” (Nirvana) with 59 days remaining and 650 points. Other entries include several 6B and 6A+ climbs from gyms such as De Campus, Nirvana, and Walhalla, with points ranging roughly from 617–643.

At the bottom of the list the average score is 631. Below that is a Sessions section showing the month March with navigation arrows.

A bottom navigation bar contains Home, Map, Gym, and You, with You highlighted.

Terminal window showing Mole, a Mac cleaning and optimization CLI tool (github.com/tw93/mole). ASCII art spells out "Mole" at the top. Below is a menu with five options: 1. Clean (free up disk space), 2. Uninstall (remove apps completely), 3. Optimize (check and maintain system), 4. Analyze (explore disk usage), 5. Status (monitor system health). Option 1 is currently selected. Bottom bar shows keyboard shortcuts for navigation, more info, TouchID, and quit.

Here is a detailed alt text for the diagram:

A technical architecture diagram titled "Roci Architecture Five-Service Design (VPS)." The diagram shows a flow of data between internal services and external endpoints, organized into three columns: External Services, Roci Services, and External APIs.

**The central flow (Roci Services) proceeds from top to bottom:**

1. **roci-matrix:** (Deno/TS, v1.0.0). Connects externally to the Matrix Network (@tijs:envs.net) via E2E Encryption. It communicates downward via an IPC socket (`/var/run/roci/agent.sock`) to the next service.
2. **roci-agent:** (Deno/TS, v2.13.0). This service receives input from the matrix service and is also triggered by a systemd timer (watch ticks) every 2 hours. It splits into two downstream paths:
* **Path 1 (Storage):** Connects via IPC (`/var/run/roci/memory.sock`) to **roci-memory** (Deno/TS, v4.1.1). This service connects via IPC (`/var/run/roci/rag.sock`) to **roci-rag** (Deno/TS, v0.2.0), which links externally to Letta Cloud (marked as deprecated).
* **Path 2 (AI Processing):** Connects via HTTP (`localhost:3000`) to **roci-llm** (Deno + Python, v1.0.0). This service connects via HTTP (`localhost:8000`) to **LiteLLM** (Python).

3. **LiteLLM:** This final internal component routes requests to External APIs on the right, specifically the Claude API, Gemini API, and GPT (marked as future).

Screenshot of a chat conversation. One message says: “A little bird told me you can do reactions now…” with a bird emoji reaction icon visible. The reply reads: “Yep! Got that upgrade yesterday. Makes things a bit more… expressive 🎉”. A red heart reaction is applied to the reply, and reaction controls are visible below the message. The message input field labeled “Bericht…” is shown at the bottom.

Flowchart of a Matrix-based messaging system. A user (Element/Matrix client on desktop, mobile, web) connects via “Matrix Protocol (HTTPS + E2E)” to a “Matrix Homeserver (envs.net)” that routes encrypted messages. “Matrix Events” flow into a VPS (Ubuntu 24.04 LTS) box containing three systemd services: roci-matrix.service (Python) for receiving messages, sending responses, and E2E encryption; roci-agent.service (Node.js) for the agent harness, tool loop (Read/Write/Bash/Grep/Glob), hooks, watch rotation, and model-agnostic LLM abstraction; and roci-memory.service (Node.js) for Letta memory blocks, state file loading, journal management, and a memory API. The matrix service connects to the agent via Unix socket /var/run/roci/agent.sock, and the agent connects to the memory service via /var/run/roci/memory.sock. Below, the memory service links to Letta Cloud (Memory Blocks) (persona, human context, patterns) and the agent links to LLM APIs (Model-Agnostic) (Claude; GPT and Gemini marked as future).

The screen recording shows the kipclip.com website where the atproto and oauth tags are selected which results in 7 bookmarks remaining, which are then shared using the 'share collection' button. Then the collection page is opened which shows the same 7 links in a simple webpage
