erm: A Local CLI That Strips Ums, Uhs, and Erms From Speech

0 CommentsEntertainment

🔥 Read this insightful post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: Linguists have a word for the ums, uhs, ers, and elongated versions (ummmm, uhhhhh) that pad spoken English: disfluencies. I don’t record a lot of voice audio, but a few friends do, and they tell me editing those out by hand is miserable. So I built erm to do it. That’s the whole interface for the common case. It writes a cleaned .wav and a JSON cut list next to the input. This post walks through how it works, because the obvious approach doesn’t sound…

coder/boo: A GNU screen style terminal multiplexer built on libghostty. · GitHub

0 CommentsEntertainment

🚀 Explore this awesome post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: A GNU screen style terminal multiplexer built on libghostty (libghostty-vt), written in Zig. Every session's output is parsed through Ghostty's terminal emulation core, so boo always knows the exact screen state of every session: contents, styles, cursor, scrollback, and terminal modes. That state is used to rehydrate your terminal on attach, to answer terminal queries for detached sessions, and to let scripts and AI agents read the screen exactly as a human would see it. Sessions that survive disconnects: detach with Ctrl-A d, reattach with…

🚀 Discover this must-read post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: Engineers at The University of Texas at Austin have developed a jacket that harvests drinking water directly from the air. The technology could benefit anyone who spends much time in areas without easy access to drinking water, from hobbyist hikers, campers and runners to agricultural workers, emergency responders and soldiers. “Water harvesting from air is usually imagined as a stationary device such as a box, a panel or a large sorbent bed,” said Guihua Yu, chair professor of the Cockrell School of Engineering’s Walker Department…

🚀 Read this awesome post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: Claude Fable is relentlessly proactive 11th June 2026 After two days of experience with Claude Fable 5 I think the best way to describe it is relentlessly proactive. It knows a whole lot of tricks and it will deploy pretty much any of them to get to its goal. I’ll illustrate this with an example. I was hacking on Datasette Agent today when I noticed a glitch: a horizontal scrollbar that shouldn’t be there in the jump menu chat prompt. I snapped this screenshot: Then…

If You are Asking for Human Attention, Demonstrate Human Effort

🔥 Check out this trending post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: An ever-increasing volume of debug investigations, document writing, and code is written by robots. This has created a new etiquette question when working with a team - when is it OK to forward the output of an AI to another human to read? On one hand, an AI with robust integration to internal code bases and documentation often produces genuinely useful output. On the other, as an increasing amount of a software engineer's day is spent reading AI text, a fatigue sets in. If…

Biological Evolution and Information Acquisition

🔥 Discover this insightful post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: A few weeks ago we looked at a simulation of technological evolution by economist Brian Arthur, in which he was able to start with simple building blocks (such as a NAND gate) and evolve surprisingly complex circuits (such as a 12-way AND gate or a 4-bit adder) by randomly combining increasingly useful existing components. We analyzed this as a way of simplifying a search problem: by using existing, working components as modules that can be combined, a few at a time, into more complex modules,…

The new "Licensed Materials" terms cover code, containers, and modules run on local machines or private cloud, and require permanent deletion of every copy on termination. Contract language for on-prem delivery tends to ship before the product it is written for.In human terms: A business evaluating a locally deployed model for security-sensitive work reads the new section and finds the exit cost spelled out: when the contract ends,…

Why I’m Forced to Say Farewell: Google Management Has Lost Its Moral Compass

0 CommentsEntertainment

🔥 Discover this awesome post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: When Google offered me the job of Director of Android Platform Security in 2017, it was impossible to refuse. Yes, Trump was already president—my family and I had qualms—but he seemed contained, even ineffective. More importantly, Google was a different company 9 years ago. Android was open source first and had just surpassed 2 billion users. I’d been studying its security from the outside since 2009, and it was (and still is!) the most exciting end-user facing operating system to work on. However, while the…

🚀 Explore this must-read post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: One of the most freeing things I’ve ever done in my business is to stop tracking time.I used to religiously track where I spent my time when on my computer. Client work in one bucket, personal branding in another, and side projects/adventures in a third. Inside of those, I would then categorize which engagement/project I was working on.At the end of the year, it was awesome! I had this huge breakdown of where all of my time went. I could even cross-reference it against what…
