Local Chatbot RAG with FreeBSD Knowledge

Out of multiple conversations with people at BSD conferences, I noticed that many would love to see a chatbot that provides precise information on FreeBSD—for users, admins, and developers. I strongly believe that there should not be an official chat.freebsd.org . Local chatbots work well and can be tweaked to fit personal needs. This documentation is written for macOS with Apple Silicon (because of the GPU support), but should work on other OSes as well. Step 1: Install Ollama (API for Multi

I'm more proud of these 128 kilobytes than anything I've built since

No FOUT About It There were some hard choices to make immediately. The first thing we discarded was webfonts, as these were bytes we simply didn’t have to spend. font-family: -apple-system, ".SFNSText-Regular", "San Francisco", "Roboto", "Segoe UI", "Helvetica Neue", sans-serif; Discarding webfonts and instead using the system font on the device had three benefits for us. First, it meant we didn’t have to worry about a flash-of-unstyled-text (FOUT). This happens when the browser renders the

Elon Musk Says He Is So Sorry for His Horrible Behavior

In February, as the disastrous effects of the so-called Department of Government Efficiency's gutting of federal agencies started to emerge, the agency's figurehead Elon Musk took to the stage of the Conservative Political Action Conference and waved a chainsaw in the air. Standing alongside Argentinian president Javier Milei, Musk wielded the shiny metal-plated prop to send a blunt message: the federal government's budget was being slashed beyond recognition. Many months later, the devastatin

Next-gen procurement platform Levelpath nabs $55M

Levelpath, a procurement software startup founded by the duo behind Scout RFP, has raised $55 million in Series B funding led by Battery Ventures as the company looks to quadruple its revenue this year. The funding round also saw participation from existing investors, including Benchmark, which led Levelpath’s $14.5 million seed round, and Redpoint, the lead investor in the $30 million Series A round announced in 2023. The startup was founded by Stan Garber and Alex Yakubovich (pictured right)

Verizon's Project 624 Is an AI-Powered Customer Service Initiative

In April, Verizon's CEO of its consumer group, Sowmyanarayan Sampath, dropped a cryptic teaser on his LinkedIn Page: "Project 624. All about the customer. Coming soon." And then… nothing more about it. Until today. Now we know that 624 represents the date, June 24, and the project is an ambitious customer service program intended to make it so subscribers can resolve issues by contacting Verizon just once. And yes, AI is involved, but don't roll your eyes just yet. Sampath laid out changes to

Software 3.0 is powered by LLMs, prompts, and vibe coding - what you need know

dan/Getty Are large language models (LLMs) our new operating systems? If so, they are changing the definition of what we consider to be software.

Introduction to the A* Algorithm (2014)

Created 26 May 2014, updated Aug 2014, Feb 2016, Jun 2016, Jun 2020, Jul 2023 Graph search algorithms let us find the shortest path on a map represented as a graph. Move the blob (start point) and cross (end point) to see the shortest path found by the A* Algorithm: A* is one of a family of related graph search algorithms: Breadth First Search[1] explores equally in all directions. Dijkstra’s Algorithm[2] takes into account movement costs. A*[3] explores more towards a single destination. In ad

The Travel Writer's Dilemma: Share, or Gatekeep?

No reviewer of books or movies faces this predicament, and if an overlooked novel or documentary suddenly wins recognition, most of us rejoice. But destinations are fragile, on several fronts — many can’t bear the weight of thousands. While sailing around Antarctica, even as I marveled at its otherworldly beauty, I was selfishly glad that not many visitors are permitted there, so precarious is its environment. Sometimes, therefore, I simply delight in the fact that my tastes are not the same as

Sitecore CMS exploit chain starts with hardcoded 'b' password

A chain of Sitecore Experience Platform (XP) vulnerabilities allows attackers to perform remote code execution (RCE) without authentication to breach and hijack servers. Sitecore is a popular enterprise CMS used by businesses to create and manage content across websites and digital media. Discovered by watchTowr researchers, the pre-auth RCE chain disclosed today consists of three distinct vulnerabilities. It hinges on the presence of an internal user (sitecore\ServicesAPI) with a hardcoded pa
