System Prompt Leaks - In the mind of ChatGPT
A collection of system message instructions for various publicly deployed chatbots. If you ever wonder what developers are whispering to GPT-5 before it answers any of your questions, this is the place to go.
For those wanting to give Agents.md a shot (see last week article), this repository can be a great source of information for designing your guidelines.
Winapps - Your Windows native apps but on a real OS
Run Windows apps such as Microsoft Office/Adobe in Linux as if they were a part of the native OS, including Nautilus integration for right clicking on files of specific mime types to open them.
GhostTrack - Track Ips, phone numbers and usernames like a ghost
Love the design of this one, and it works quite well. I tried it to track myself (like a ghost). I didn’t manage to find where I had left my keys, but at least the information was accurate.
Not too sure what you’re supposed to do with it once the fun phase is over, though.
Microsoft VibeVoice - Your new State of the audio deepfake generator
VibeVoice is a framework designed for generating expressive, long-form, multi-speaker conversational audio such as podcasts from text. Backed by Microsoft, the repo is already widely used to generate media content (including plenty of low-effort YouTube videos).
By the way, if you’re not yet familiar with AI-generated junk on YouTube, go check some out it honestly feels like it’s trying to inject dopamine straight into your brain. To get you started: https://www.youtube.com/shorts/HaTAhsgk_l0 (140 millions views already)
