enjoying the summer vacation with my family at the sea

An adult and a child sit on a concrete edge by the water, facing a marina with many sailboats docked. The adult, wearing a turquoise and blue jacket with a patterned hat, points towards the boats, while the child, dressed in a light-colored hooded jacket with star patterns, sits closely beside them. The sky is overcast, and the water is calm, reflecting the masts of the sailboats.

one year later

Masked rebel operative in tactical gear leaps over crates inside a dark industrial compound, surrounded by fiery explosions and swirling purple-red nebula waves. A glowing nebula portal and an erupting planet blaze in the background, with ‘S02E01 – One Year Later’ stenciled onto a metal wall.

new video dropping soon:

replacing my job at @runpod.io with agents: can mastra.ai really do it?

YouTube thumbnail showing a bald man with glasses and a surprised expression, pointing upward with his index finger toward a flowchart labeled "janitor." The flowchart outlines four main steps: git checkout, docker validation, repair, and pull request. Supporting tasks like build image, run container, check logs, list files, read file, write file, and search are shown underneath in a section labeled "dev." Additional labels include "Tool4CE-2-Llama-3.1-8B" and "claude-3.5-sonnet," indicating AI agents used in the process. The background is black with white text, creating a clean and modern tech-focused look.

dropping tomorrow

A screenshot of a chat interface titled “chat with DeepSeek-R1-Distill-Qwen-1.5B.” The user messages “hello, whats up with you?” and later asks, “how are you feeling tomorrow?” The AI assistant responds that it doesn’t have feelings, clarifying it is a virtual assistant ready to help, and includes a reasoning section about its neutral, chatbot-like nature.

democratize ai = free + private + local + open source access to ai for everyone

last thursday i introduced wandler at the DataStax Berlin AI meetup. my talk, "democratize ai with the browser," showcased how to break down the barrier between web devs and ai running in the browser with js.

A smiling, bald man named Tim Pietrusky holds a microphone and takes a selfie in front of a large group of people seated in rows. Many in the audience are smiling, waving, or giving thumbs up in a well-lit event space with chairs and an open floor area.

the feeling when updating cursor fails...

A Windows-style dialog box labeled “Cursor” with a red error icon. The message reads: “There was an error while Renaming: ‘tools’: Access is denied. (os error 5). Please verify there are no Cursor processes still executing.” Below are two buttons: “Retry” and “Cancel.”

lfg cursor + claude-3.7-sonnet

A screenshot of a dark-themed chat interface. In the text input field, the user has typed “lfg.” Above it, a button labeled “Add context” is visible. At the bottom, the agent selection reads “Agent Ctrl+I” with the model “claude-3.7-sonnet,” and a “Send” button is on the right. A plus icon and a back arrow appear at the top of the window.

let's jump into the actual fun here

without generating a new file, i had a file called "cat" on my computer containing the same code we saw in cursor agent

this file is full of hidden characters

SSUUMMMMAARRYY OOFF LLEESSSS CCOOMMMMAANNDDSS

Commands marked with may be preceded by a number N. Notes in parentheses indicate the behavior if N is given.A key preceded by a caret indicates the Ctrl key thus K is ctrlK

vibe coding in cursor and out of the sudden it tries to run

git log --since="2024-03-20" --pretty=format:"%h %s" | cat

to find my recent commits

and ended up in a total clusterfuck called

A multi-pane terminal window. On the left, a file navigator shows directories like 'clients', 'workers', 'submodules', and files including 'readme.md' and 'server-setup.md'. In the center, a pane displays a 'cat' command with references to 'C Cat'. On the right, a help-like text discusses commands marked with * or ^, explaining that ^ indicates the Ctrl key. Sections titled MOVING and SEMANTIC COMMANDS outline navigation keys (j, k, space, etc.) and mention pressing RETURN or 'q' to exit.

Below, another pane or window references the same text in a terminal command:
$ git log --since='2024-03-20' --pretty-format:'%h %s' | cat
followed by the same help content about commands, exit keys (q, Q, ZZ), and line-by-line navigation.

gm

A gentle forest slope with tall, slender trunks of both coniferous and leafless deciduous trees. The ground is entirely blanketed in dry, brown leaves, forming a soft trail that curves into the distance. Moss-covered patches of earth appear in spots along the left side. The sky peeks through bare branches, lending a subdued, wintry atmosphere.

end the day with altered carbon

A dimly lit room with a large projector screen showing a close-up of a man with short blond hair, his gaze directed upward. Across the bottom of the screen, white subtitle text reads, “You have 3,578 death threats left to view.” The background behind him is blurred in cool, bluish tones. Below the screen sits a small table holding a compact projector. Near the ceiling, a pink balloon or decoration hangs, adding a hint of color to the otherwise dark space.
