This week has been all about LocalLLM experimentation. Google Releases Gemma4 - Google DeepMind released Gemma4 and I’ve been experimenting with it. The boilerplate for this post’s markdown file was automatically written by gemma4:26b. It wasn’t as fast as Claude Code, but it worked equally well. Jan.ai - I found out about this in an HN thread suggesting alternatives to Ollama. I’m a little sketched out by how difficult it is to find info on who produces it - much lik LM Studio. But, it’s open source and on Github, properly attributes the projects it’s built on, and offeres a lot of customization, so I’m giving it a go. ...

Gemma4 LocalLLM Resource Usage

For the past few months, I’ve been using Zed because its coding assistant and AI features fit better than other editors’. I’ve been using Zed’s built-in Claude agent to help me write code for toy programs, generate blog post boilerplate, and review blog posts to ensure I’m completing my ideas. I’ve been using a Mac with 40 GPU cores, 48GB Unified RAM, and 546 GB/s memory bandwidth and have been toying with models to find the most capable model per GB of memory. I try to keep my used swap at 0 as a self-imposed constraint, so I am interested in finding the model that can live within 5-20GB or so. ...

Claude Mythos Preview

Introduction Yesterday, Anthropic revealed information about Mythos, the successor to Opus 4.6. From their initial reporting, Mythos will have capabilities far surpassing those of existing frontier models - especially in the cybersecurity domain. These capabilities are currently being deployed in Project Glasswing: a joint initiative between Anthropic and several leading American tech companies, including Apple and Crowdstrike, to use Mythos to secure software produced by those companies. Anthropic’s Red Team posted additional details about vulnerabilities identified by Mythos, including their testing methodology details. ...

Claude Code Source Code Leak - Reporting indicates the Claude Code source was leaked via a .map file pushed to the npm registry. As a Security Operations guy, I am simultaneously surprised and unsurprised by this: On one hand, I would expect a company with the resources at Anthropic’s disposal to have world-class processes and monitoring in place to prevent such disclosure. On the other, even at a company operating at Anthropic’s scale, I imagine the information security team may not be involved with the activities of all teams. Ollama gains MLX Support - This is in preview, and seems to only work for one model according to the blog post, but I’m beyond excited. I wrote last Summer about Ollama and LM Studio. More tools have released since then, including omlx that are compelling alternatives to Ollama. I’m glad to see them catching up in this regard. ...

Apple at 50

Apple was founded on April 1, 1976 — fifty years ago today. I can’t say I grew up with Apple devices: ours was an IBM PC and eventually a Windows NT household because that’s what Mom and Dad used at work, and because I fell in love with video games at age five. We did have Apple Macintosh IIs in my elementary school classrooms, however, and I would race to finish my work early so I could play SimCity or KidPix. ...

USA Debt Clock - It’s depressing to look at, but I remind myself of this periodically. TurboQuant - I’m excited to see if this technology can reduce the resources needed to run AI. LiteLLM Package Compromise - As defenders lock down the attack surface of organizations, attackers will adapt and find ways to exploit vulnerabilities or weaknesses in other areas. Supply chain attacks are nothing new, but this one is remarkable. ...

I traced $2 billion in nonprofit grants and 45 states of lobbying records to figure out who’s behind the age verification bills. The answer involves a company that profits from your data writing laws that collect more of it. : linux - I love effective citizen journalism. Ghostty 1.3.1 release - This release fixes some macOS-specific issues. I’ve been a huge Ghostty fan since it hit general availability, and just yesterday, ran brew uninstall --cask iterm2. ...

Firefox Is Cooking

Mozilla published a blog post on Tuesday that excited me for several reasons: More reasons to love Firefox: What’s new now, and what’s coming soon Communications First, I appreciate the improved communication. Along with recent posts like AI Controls are coming to Firefox, Mozilla has been teasing new features and creating anticipation with these product posts. These articles show that Mozilla is proud of what its building and wants to raise excitement. For me, it’s working! ...

Partnering with Mozilla to improve Firefox’s security \ Anthropic - Inspiring writeup about how Anthropic and Mozilla leveraged Claude Opus 4.6 to identify and fix several dozen moderate-to-severe security flaws. The key takeaway for me from this article is the following: Opus 4.6 is currently far better at identifying and fixing vulnerabilities than at exploiting them. This gives defenders the advantage. And with the recent release of Claude Code Security in limited research preview, we’re bringing vulnerability-discovery (and patching) capabilities directly to customers and open-source maintainers. ...

Notes on Setting up Open WebUI with Ollama

Some time ago, I wrote about Local LLMs and specific pain points (like weeping as memory and swap usage shoot through the roof). One of these pain points is not having a single frontend from which I manage and interact with models. This approach may be slightly antiquated in the age of OpenClaw, but as OpenClaw security issues mount, I’m convinced it would be best to start with the basics before moving onto automation that exposes my device to Remote Code Execution (RCE). ...
