Ubuntu Firewall Setup in Less Than 5 Minutes (Plus One Step That Will Lock You Out)

Setting up a Virtual Private Server (VPS) without a firewall is asking for trouble. Ideally, you’d have a dedicated security person to handle all of this, but that’s rarely the case. One thing I always do on a fresh Linux server is configure a firewall. It used to be a real headache, but […] The post Ubuntu Firewall Setup in Less Than 5 Minutes (Plus One Step That Will Lock You Out) appeared first on PHP Architect.

Socket for Jira Is Now Available

Security findings only matter if organizations can act on them. That usually means getting the right issues into the systems where engineering and security teams already work. Socket for Jira is now available, making it easy to turn Socket alerts into Jira issues and keep remediation work moving as alerts change over time. Teams can create tickets manually from individual alerts or set up automated ticketing rules to create, update, and resolve issues based on activity in Socket. The…

llm-openrouter 0.6

Release: llm-openrouter 0.6 llm openrouter refresh command for refreshing the list of available models without waiting for the cache to expire. I added this feature so I could try Kimi 2.6 on OpenRouter as soon as it became available there. Here's its pelican - this time as an HTML page because Kimi chose to include an HTML and JavaScript UI to control the animation. Transcript here.

SQL functions in Google Sheets to fetch data from Datasette

TIL: SQL functions in Google Sheets to fetch data from Datasette I put together some notes on patterns for fetching data from a Datasette instance directly into Google Sheets - using the importdata() function, a "named function" that wraps it or a Google Apps Script if you need to send an API token in an HTTP header (not supported by importdata().) Here's an example sheet demonstrating all three methods. Tags: spreadsheets, datasette, google

Claude Token Counter, now with model comparisons

Claude Token Counter, now with model comparisons

Claude Token Counter, now with model comparisons I upgraded my Claude Token Counter tool to add the ability to run the same count against different models in order to compare them. As far as I can tell Claude Opus 4.7 is the first model to change the tokenizer, so it's only worth running comparisons between 4.7 and 4.6. The Claude token counting API accepts any Claude model ID though so I've included options for all four of the notable current models (Opus 4.7 and 4.6, Sonnet 4.6, and Haiku…

Headless everything for personal AI

Headless everything for personal AI Matt Webb thinks headless services are about to become much more common: Why? Because using personal AIs is a better experience for users than using services directly (honestly); and headless services are quicker and more dependable for the personal AIs than having them click round a GUI with a bot-controlled mouse. Evidently Marc Benioff thinks so too: Welcome Salesforce Headless 360: No Browser Required! Our API is the UI. Entire Salesforce & Agentforce…

Changes in the system prompt between Claude Opus 4.6 and 4.7

Changes in the system prompt between Claude Opus 4.6 and 4.7

Anthropic are the only major AI lab to publish the system prompts for their user-facing chat systems. Their system prompt archive now dates all the way back to Claude 3 in July 2024 and it's always interesting to see how the system prompt evolves as they publish new models. Opus 4.7 shipped the other day (April 16, 2026) with a Claude.ai system prompt update since Opus 4.6 (February 5, 2026). I had Claude Code take the Markdown version of their system prompts, break that up into separate…

Claude system prompts as a git timeline

Research: Claude system prompts as a git timeline Anthropic publish the system prompts for Claude chat and make that page available as Markdown. I had Claude Code turn that page into separate files for each model and model family with fake git commit dates to enable browsing the changes via the GitHub commit view. I used this to write my own detailed notes on the changes between Opus 4.6 and 4.7. Tags: system-prompts, anthropic, claude, generative-ai, ai, llms

Adding a new content type to my blog-to-newsletter tool

Agentic Engineering Patterns > Here's an example of a deceptively short prompt that got a lot of work done in a single shot. First, some background. I send out a free Substack newsletter around once a week containing content copied-and-pasted from my blog. I'm effectively using Substack as a lightweight way to allow people to subscribe to my blog via email. I generate the newsletter with my blog-to-newsletter tool - an HTML and JavaScript app that fetches my latest content from this…
