Inference at the Edge: Running a Large Language Model Chatbot on Consumer Hardware Updated

Generative artificial intelligence and conversational chatbots like ChatGPT have made headlines in recent months. These virtual assistants sound nearly human because they are based on extremely large datasets that contain real human conversations or other sources of data that contain the desired output for a given input.  Hobbyists and open source enthusiasts are experimenting with ways to run size optimized versions of large language models that have been tuned for instruction based interaction with humans and run locally on consumer-grade hardware.

A Primer on Conversational Artificial Intelligence Agents & Large Language Models Updated

Conversational agents and the large language models (LLM) at their core have become increasingly proficient at mimicking human language and behavior, so that they can respond to a wide variety of instructions. They have been shown to be effective in many different tasks such as question and answering, dialogue generation, text summarization, machine translation, and even programming. But the questions remain: do LLMS actually know anything? And, how do they actually work? Continue reading A Primer on Conversational Artificial Intelligence Agents & Large Language Models Updated

How To: Watch Movies in Your Honda Pilot or Odyssey Using Android TV Updated

We recently purchased a 2018 Honda Pilot Touring edition that has a rear entertainment system (RES). In addition to playing Blu-rays, DVDs, and CDs, the Honda entertainment system can play anything that connects via either an HDMI or component auxiliary video input. My wife asked me for a media solution that was as simple as inserting a DVD disc but that permitted us to play a number of movies on demand for our children.

How To: Deploying a Ubiquiti UniFi Home Network including Multiple WiFi Access Points (Part 2) Updated

Following are my recommended configuration changes for an optimized Ubiquiti UniFi home network. I use them in our home with a gigabit-speed Internet connection. To get the best results, you will need to tune your wireless home network. This includes accounting for neighboring networks, interference, the density of your APs, the number of your wireless clients and their idiosyncrasies in terms of wireless standards support. If you don’t use Sonos, IoT, or femtocell devices, some of these settings below may not be necessary for you.

Sonos One & Sonos Beam (Part 2): Review of Voice Services Including Amazon Alexa, Google Assistant & Apple Airplay 2 Updated

Sonos speakers will be able to bridge the gaps between Amazon, Apple, and Google’s smart home ecosystems. Sonos owners will be in the unique position of choosing their preferred voice assistant for a task, independent from the music source, method of streaming, or smart home control. For example, a Sonos owner could maintain their music library in iTunes, their music subscription service on YouTube or Amazon, their home control on Apple HomeKit, and ask general knowledge questions to Google Assistant or Alexa. Similarly, Sonos consumers could control Nest and HomeKit devices from a single smart speaker.

Sonos One & Sonos Beam (Part 1): The State of Smart Speakers Updated

Amazon Echo’s primary function appears to be extending Amazon’s ecosystem including e-commerce and advertising. Like Amazon, Google Home’s primary goal appears to be lowering the price of its devices so that users will install multiple devices in their homes, generating more user data for Google’s advertising business. Apple’s product design treats smart speakers as a relatively dumb and local extension of the iPhone. The Sonos One hits the price-performance sweet spot: although it costs nearly twice what an Echo or Home does, it provides significantly better sound.

How To: Play HD Radio Throughout Your Home Using Google Cast or Airplay

Not every radio station is available in a high fidelity (high bitrate) format online. So, for some local radio stations, you are better off tuning them over the air. Fortunately, many broadcasters in the US also broadcast a digital signal, “HD Radio”. The challenge is how to create a local server to stream the HD Radio station to either Google Cast or Airplay-enabled devices.

How To: Optimizing Your Multiple Access Point, Wireless-AC WiFi Network (Part 1)

Mesh-network based, multi-unit WiFi access point solutions from Google, Eero, Luma, and other vendors are popular now. Compared to typical networking gear, they look unobtrusive, so you won’t mind placing the access points out in the open for maximum wireless reception. Mesh WiFi systems connect multiple units (nodes) to move data from the client to the router. If your goal is to fill in wireless dead zones with the minimal amount of installation effort (meaning no wire pulling), then this approach will give you the largest coverage but at the expense of throughput.

How To: Upscaling Lower Resolution Video to 4K Updated

So you just bought an expensive new 4K (UHD) television set. The issue is that most live and recorded video distributed today is less than 4K (2160p) resolution. Blu-rays are 1080p format while DVDs are only 480i/p. TV broadcasters use either 1080i or 720p. Some cable and satellite companies are downscaling 1080i to 720p format. Although some over-the-top video service providers like Amazon and Netflix have select content in 4K, most of their content is in 1080 resolution. To solve this, UHD TVs include upscalers for lower resolution content originating from cable/satellite settop boxes, Blu-ray and DVD players and gaming consoles. Continue reading How To: Upscaling Lower Resolution Video to 4K Updated
