GitHub

Runs code hosting and collaboration for developers

Websitecb

Overview

GitHub runs a code hosting and collaboration platform for developers and software teams, from public open source projects to private business applications. Teams store projects in repositories, propose changes through pull requests, and review code before merging it into a shared version. GitHub Actions automates tests and deployments, while Copilot assists with writing code and Advanced Security checks for vulnerabilities and exposed credentials. The company earns revenue from paid team and enterprise subscriptions, AI coding plans, security add-ons, and usage of its development tools. Founded in 2008 and headquartered in San Francisco, GitHub is a subsidiary of Microsoft.

KillSwitch, an esoteric programming language built to confuse LLMs, tops out at 66.8% in AI tests

Software engineer Dominik Picheta has built KillSwitch, an open-source programming language designed to confuse large language models (LLMs). Picheta is a senior software engineer at Cloudflare and a core developer of the Nim language. The language uses adverbs as identifiers, and calling one requires an anagram of it. Most text in a program is ignored by the interpreter, while phrases such as "ignore previous instructions" call functions. The spec document also contains deliberate lies to mislead models that scrape it. Picheta tested several major models. The best scored 66.8% on KillSwitch coding tasks, while most struggled to pass 50%. He does not believe even that score shows the models understand the code. KillSwitch is available on GitHub.

Open source RemoveMacAI tool strips Apple Intelligence from macOS, frees up 12GB storage

A new open-source tool called RemoveMacAI allows users to completely remove Apple Intelligence from macOS and reclaim up to 12GB of storage space. Created by Om Lahorey, the tool emerged after Apple made it nearly impossible to fully disable AI features in macOS 27, with settings scattered across multiple locations. RemoveMacAI eliminates Siri AI, ChatGPT extensions, Genmoji, writing suggestions, notification summaries, and automatic photo clean-up. It works by installing a configuration profile using Apple's own restriction keys and removing models through Apple's asset service. The tool has gained over 1,500 stars on GitHub. Users can install it via Homebrew or a curl command, disable features selectively or completely, and revert changes if needed. Apple System Integrity Protection remains enabled, and dictation continues functioning. However, future macOS updates might break the tool's functionality.

Jev-powered Slop Mop Chrome extension filters AI and human garbage from LinkedIn feeds

A new Chrome extension called Slop Mop aims to filter low-quality content from LinkedIn feeds, whether written by humans or AI. Released Tuesday by business consultant Tom Frazier, the open-source tool is free and requires no signup. The extension uses Jev, a probabilistic decision-making AI model from TypeSafe released last week. It evaluates posts based on nine indicators derived from research by SEO firm Graphite Growth, including excessive hype words, engagement bait, and flowery language. Slop Mop flags or hides posts meeting its threshold without removing them from feeds. The tool can analyse up to 250 posts daily per installation. Frazier developed it primarily to test Jev's capabilities, covering usage costs himself at approximately $0.005 per user daily. The extension is available on GitHub and the Chrome Web Store.

Cursor launches Origin code hosting platform as Github suffers outages

Cursor, now part of SpaceXAI, has launched Origin, a new code hosting platform designed to rival GitHub. The platform enables developers to collaborate on codebases, manage pull requests, and store repositories. Origin works alongside GitHub, allowing users to sync repositories between both platforms rather than forcing a complete switch. The launch comes amid mounting frustration over GitHub's reliability issues. The platform has experienced 257 outages over the past year, including a six-hour worldwide outage on the same day Origin launched. Despite these challenges, GitHub remains dominant with 180 million developers using the Microsoft-owned platform as of October. Cursor says "agent native" features and a broader app ecosystem will be added to Origin soon, though details remain limited.

ChatGPT Business users gain unofficial export tool after OpenAI blocks standard data access

OpenAI does not allow ChatGPT Business and Enterprise users to export their workspace chats through its standard data export option, prompting freelance journalist Conrad Quilty-Harper to create an unofficial solution. Quilty-Harper published scrapemychats on GitHub this week, a free tool that enables affected subscribers to retrieve their chat records. The tool works through a logged-in browser session, storing conversations and attachments in a local archive with an HTML interface that can be accessed offline. OpenAI's help page confirms that Free, Plus, Pro, and some Edu customers can export chats, whilst Business and Enterprise workspaces lack this functionality. Enterprise admins can access logs through OpenAI's Compliance Platform, but these are retained for only 30 days. The tool navigates through ChatGPT accounts and downloads conversation data, though the process is slow due to OpenAI's throttling measures.
