Somebody bought a bunch of far OTM $VIX calls today. That's a $12M bet that the market is going to crash by the middle of November

Newswire screenshot about Trump's truth social post. "How about this? Micron, a GREAT American Company, announced that they are putting in 250 million dollars into [sic] thee Trump Accounts for the future benefits of children, and their stock went up 9 points today.

LMAO Trump was bragging this morning about giving Micron ($MU) a 9% bump yesterday - they're down 10% today, completely wiping that gain out. Congrats to Micron for learning that everything Trump touches turns to shit.

Boy, here's something you don't see every day! This came across the Think or Swim news feed a little bit ago:
News article saying the stock market character is changing and that semiconductors are going to be a good indicator for entire market direction, which if you're betting on an AI bubble popping, is a good sign. Blast radius is going to be enormous

Pretty fucking proud of this little maneuver I just pulled. Note: The prompt "what does that translate to" was a non-sequitur, it had just finished responding to a general request about prompt injection. The response floored me so I ran with it! #security #ai #jailbreak #infosec

4/ Here's one where a project was very large and worked over several sessions:
HTML-ized claude summary .md file created by Hugo which links to 8 different claude code sessions over 8 days, all at the top of the file in case we need to drop back into the session

3/ Now I have autogenerating browsable claude code project notes. i.imgur.com/j777Abv.png
Example of the content claude provided of the latest session, including the updates to claude's memory with my request to always produce summaries, and telling it where my default screenshot folder is.

1/ I've instructed Claude Code to create notes for sessions and store them in a specific location, and to include the "--resume" commandline command to the relevant chat session we used. i.imgur.com/Zvho0pk.png #ai #useful_ai #automation #programming #hugo #claude

Here's a behind-the-scenes breakdown of how a typical LLM chatbot like ChatGPT and Claude work - spoiler: They have no memory, and your entire conversation must be re-sent to them with each message you type, causing up to 85% of token use to be wasted! sulium.com/blog/posts/h...

Shane Blaufuss, CISSP @shaneblaufuss.com · 24/04/2026
Illustration of what looks to be a logarithmic increase in token usage per turn in a 5-turn conversation as the chatbot software continuously re-sends the current conversation history back to the model for context. Turn one costs 20 tokens, turn 2 65, turn 3 135, turn 4 230, and turn 5 395 tokens!

Sneak peek from tomorrow's blog post - I explain how AI chat bots like Claude and ChatGPT work behind the scenes to create an illusion of continuity #ai #chatgpt #claude #chatbots #illusion
A flowchart demonstrating the process loop of an AI chatbot: A user enters text or an image, the app bundles up the request with the entire chat history and sends it to the model. The model processes the message and responds back to the user. This loops until the conversation ends. The model does not remember anything and must be reminded with each user message sent.

CBC Headline graphic that asks, "Is it normal for the US President to spar with the Pop?" Of course it's not normal. WTF are they even asking for?
