Polymarket Trading Bot:How to Build a Market Maker Bot: Order Management, Limit Orders, and Partial Fills

Day 5 of 7: Building a Polymarket Market Maker Bot From Zero to Complete In Day 4, we explored how a Polymarket market maker bot calculates bid and ask prices, manages spreads, and adjusts quotes based on inventory. But calculating the right price is only half the job. What happens after your bot places an order? Imagine your Python trading bot wants to buy YES tokens at $0.48 and sell them at $0.52. Before either order fills: If your bot cannot handle these situations, even a good market-making strategy can lose control of its positions. In this tutorial, we'll explore how to build the order-management foundation of a Polymarket trading bot. The examples use Python and Decimal for financial values. They demonstrate the decision-making logic, not a complete integration with the live Polymarket API. Order management is the part of a trading bot responsible for controlling the orders it…

Anthropic now lets Claude users jump out of plane without parachute

Anthropic, prone to pronouncements about model safety, has given developers using Claude Code the opportunity to throw its guardrails out the window. The company's latest Claude Code build (v2.1.311) supports an environmental variable designed to allow the AI agent to run the rm command, which deletes files, without asking for approval. The designated environmental variable (a value developers set in their shell) is called: Daisy Hollman, a member of technical staff at Anthropic, announced the change in a social media post. Not everyone believed Hollman, perhaps due to the absurdity of the variable name or because the change isn't listed in the v2.1.311 change log. But she offered reassurance that it's real. "Not a joke!" she responded. "I hope this helps, and I hope the variable name is memorable." The name is easy to remember because it is very much like the aforementioned Claude Code…

Alternatives to Tailwind CSS: Name the Complaint First

I defend Tailwind more than I probably should, which makes me a biased judge of its alternatives. So this post is me trying to write down the honest case for leaving, then checking which of the alternatives actually survive it. Short version: most people who search for alternatives to Tailwind CSS don’t need a different framework. They need to know which of four complaints they have, because each one has a different fix, and two of the fixes are plain CSS. Tailwind complaints tend to come bundled together, and they shouldn’t be. Pulled apart, I hear four of them. The first is markup noise. A card with eleven classes on the wrapper and six on every child is hard to scan, and it’s hard to review in a pull request when the real change is one class in the middle of a long string. This one is legitimate. Components help, but only if you actually extract them. The second is the build step.…

How to Learn Vim (and Actually Remember the Commands)

Most people who try Vim quit in the same week. They run vimtutor, get through it in half an hour, feel pretty good, and then open a real file on Monday and can't remember how to delete a word. So they reach for the arrow keys, then the mouse, then VS Code. I don't think the problem is Vim being hard. It's that people learn the commands once and never see them again until they need them under pressure. If you're searching "how to learn Vim," you'll find cheat sheets with 150 commands on them. Skip those for now. This post is about learning a small set well enough that your fingers know it, and then growing it slowly. vimtutor ships with Vim. Type it in a terminal and you get a plain text lesson you edit as you go. It covers moving around, deleting, changing text, undo, search and saving. It takes about 30 minutes. Do it once. Then stop reading tutorials for a while. The tutor gives you…
