  • Generative AI tools further the importance of quality over quantity in employee evaluation. Another key future skill: managers who can spot true excellence amid AI-enhanced mediocrity.

  • Meta/AI and wearables

    Nilay Patel and Mark Zuckerberg Podcast notes:

    – I’m on board with the idea that computing’s future is shifting away from mobile towards wearables, likely eyeglasses. Might be worth looking into Luxottica investments given their Facebook partnership.

    – The concept of companies using AI chatbots as customer-facing agents with real agency? Yes, I can see that happening. These AI instances could represent brands, proactively engaging customers through messages, ads, etc.

    – AI-generated content in social media feeds seems inevitable, but I’m not thrilled about it. It’s unlikely to match the novelty or appeal of human-created content. However, the idea that social networks’ role is to spark conversations in private channels is intriguing. Take TikTok, for instance – people watch videos there but share and discuss them in private chats elsewhere.

    – There’s definitely going to be a demand for user-friendly, private channels that offer more than just text messaging. But can anything really beat the richness of a letter with a photo? I’m not so sure.

  • Of all the new features on ios 18, the one that no one has talked about and that has made the most impact on my day-to-day life is that Siri now AutoCorrects wanna to “want to.”

  • I’m not sure if it’s just me or if it’s a universal experience for musicians but: periods of progress and improvement when practicing my instrument usually translate—at least temporarily—to lousy public performance.

  • The Right Amplifier

    A few years ago I picked up a pair of KEF q150 speakers for my small listening room, at the time I had them paired with a NAD 7125 amplifier. When I first fired up that pairing I was a bit dissapointed in how bass-heavy everything sounded. I learned that the KEF’s came with some foam baffles that I could put in the back of the speakers and that helped a lot. I ran that setup for a couple of years.

    Yesterday while cruising FB marketplace I came across an older Cambridge Audio amp for cheap- the 340a. I wired up the speakers and at first was shocked at how much less power the Cambridge had from a sheer volume perspective but, that said, the room is so small that it’s plenty of power, just much much less than the NAD.

    But more importantly, the overall frequency response is light years better than the NAD. I was able to take the foam baffles out of the back of the KEF’s. The high end is a little less brittle than the NAD which just makes the overall stereo imaging feel that much better.

    People rave about the KEF’s. I was honestly a bit dissapointed with them and was always keeping my eyes out for possible replacements but paired with the right amp, they are a killer pair of speakers, especially if you can find them used.

  • Delaware Valley Bluegrass – 2024

    This is the best bluegrass festival, period. The size is perfect. One stage, no lines, nothing is crowded* Almost everyone who attends plays an instrument so the campground jams can be amazing.

    (*except the handicap bathroom stall of which there is only one and when you’re helping someone navigate the festival in a wheelchair that makes it tough, but that’s my only complaint.)

    Del McCoury’s set was legend. Just kept on going. At 85 years old they had to practically drag him off the stage at 11PM. Del feels like the last living bridge to Monroe from a musical and performance pov and his band is the quintessential traditional bluegrass sound.

    Asleep at the wheel also killed it. The intricacy of the unison/harmony parts on fiddle, pedal steel, guitar and sax was just awesome to watch. They made it look soooo easy which is half of the appeal given how complicated Western swing is.

    I didn’t get in nearly as much playing as I’d hoped but it was great to know that scattered across the fairgrounds were pockets of players who I knew and had jammed with in the past so that, had I had more time to play, I could have jumped into any of several different sessions.

    Guitar nerd notes: I’ll add that the picking I did do was on my D-18 which i strung up with martin PB lifespans (13/mediums) just before leaving for DelVal and the guitar just felt so lifeless compared to my 28. It was a challenge to really make any music on it. It did start to feel better towards Sunday morning so either the strings needed to break in a bit or i got used to the lifelessness of it. I don’t know. I haven’t played my 28 since I’ve been home. I need to do a side by side. I did play my OM-18 when I got home and that is the most comfortable guitar to play but i need new strings on it.

  • Greyfox 2024 Highlights

    Molly Tuttle

    Molly Tuttle’s show was light years beyond anything that’s ever hit the main stage at Greyfox. Unlike most other artists, Tuttle and her band brought their own lights, equipment, and sound team. This initially seemed strange, given the festival’s typically excellent sound management. However, minutes into her Friday night show, it became clear why: the lights and processing effects used for her performance were amazing, strategically synced to specific moments in each song, adding a new dimension to her music.

    Her band is incredible. Bronwyn Keith-Hynes on fiddle, Dominick Leslie on mandolin. Incredible lineup. Was very cool that halfway through the show they called onto stage the McCoury’s fiddle player, Jason Carter, to announce that he and Bronwyn are getting married. The two of them playing together was a real treat.

    Just as I thought, “This is great but straying a but too far from traditional bluegrass,” Tuttle seamlessly transitioned to performing a string of songs with her band around a single mic at center stage, sans effects. This versatility showcased their ability to excel in both modern and traditional styles. Tuttle’s songwriting shines through, particularly in her masterpiece “Crooked Tree.” She is 100 times the musician/songwriter of Taylor Swift. Her candid discussion of her alopecia diagnosis, culminating in the removal of her wig, created a genuinely emotional experience for the audience.

    Le Vent du Nord

    Highlights: Quebec-based band, unique sound, exceptional musicianship

    Le Vent du Nord from Quebec initially sounded bizarre on paper, but their performance on the Catskills stage was mind-blowing. Their act was unlike anything I have ever seen or heard before, featuring an extraordinary level of musicianship and a unique stage presence. The experience was so impactful that it would warrant immediate ticket purchases for any future performances in the area. More information about the band can be found at https://leventdunord.com/en/ I really do not know how to explain these guys so perhaps YouTube would be a good way to learn more about them.

    Hawktail

    Highlights: Trio formation, captivating live performance, “Chambergrass” genre

    Hawktail, (once a quartet but MT’s mando player, Dominick Leslie) now a trio consisting of fiddle, guitar, and bass, delivered a super engaging performance at the intimate Creekside stage. Despite my preconceptions of their music being suitable for napping, their live act challenged this notion entirely. The power and emotion conveyed in their performance, coupled with their exceptional musicianship, interplay, and dynamics, made for a captivating experience. Watching them perform live was akin to witnessing six hands working in unison to construct a musical sculpture that materialized and vanished with each tune. I can not wait to see this band again. Here’s a good taste of the band (from last year with Leslie on mandolin) definitely watch all the way through to Brittney Haas’ killer fiddle solo at the end of the video.

    Darol Anger and Bruce Molsky

    Highlights: Experienced fiddle duo, memorable rendition of “I Wish I Knew How It Would Feel to Be Free”

    This fiddle duo’s performance on the small Creekside stage was a delight to watch. Their music and the interplay between them reflected a long-standing musical relationship. Their rendition of “I Wish I Knew How It Would Feel to Be Free” was particularly infectious. As soon as i got home I learned the chord changes to this piece. Upon doing a further dive on this piece, I can not recommend enough watching Nina Simone’s heart-wrenching performance of the same song at the 1976 Montreux Jazz Festival.

    Other Notable Performances

    Twisted Pine offered a fun twist on Bluegrass/Americana (or “fringe Americana”) by incorporating a flute into their ensemble, making them worth checking out. Brennan Leigh was excellent to watch. She’s a gifted songwriter/storyteller. Travelin’ McCoury’s killed, as always. I don’t think there are higher caliber musicians playing anywhere in any genre of music.

    The Sam Grisman Trio/Project delivered performances that lived up to the expectations set by Sam’s musical pedigree. Having grown up with Jerry Garcia playing in his basement, Sam showcased great musicianship and stellar song choices. His evening electric show with a drummer, where he played electric bass, provided a different but equally excellent vibe compared to his acoustic performances.

    I saw a lot of other great bands but these stood out as highlights and are likely to inspire further exploration of their catalogs in the coming year.

  • AI/LLM Interfaces

    I’m testing out msty as a way to compare some different AI tools. The ability to create “knowledge stacks” (and, moreover, use different models for embedding that knowledge for RAG) is really amazing.

    Here I took some VW training materials and couple of YouTube links and created a “Volkswagen Vanagon” knowledge stack using 2 different embedding models: Snowflake Arctic and OpenAI’s Text Embedding. The tradeoff here is that by using Snowflake, you’re keeping the embedding local as you’re running that model locally, the openai text embedding requires you send the content via API to OpenAI for embedding.

    Next, I used GPT-4o and Claude3 Opus to interrogate the training materials. The ability to see this output side by side is helpful.

    open this in a new tab and zoom if you want to read output.

    SO here we see from left to right:

    GPT w/ Snowflake, GPT w/ OpenAI Embedding, Claude with Snowflake and Claude with OpenAI Embedding

    As I know a bit about Vanagon idle issues, I’d say that if I had to rank these responses, Claude with OpenAI embedding barely beats out GPT’s Open AI embedding simply because it communicates the same info as GPT but slightly more user-friendly.

    Next would be GPT using the Snowflake embedding which gave accurate though not thorough or complete information. Finally, Claude with Snowflake was a total fail.

    That said, I could probably tweak the prompting a bit and get a slightly different set of responses.

    I then tried the same query using a local LLM, TinyDolphin, which msty installs as a default option and had it query both the Snowflake embedding and the open AI embedding.

    The TinyDolphin + Snowflake, importantly, is an entire local process. All data, processing and embedding happens locally. Here is the response:

    To troubleshoot the idle issue on your 1986 Vanagon, follow these steps:

Inspect Vacuum Lines: Check for any leaks or disconnections in the vacuum lines and hoses.
Clean the Idle Control Valve: Remove and clean the idle control valve to ensure it isn't clogged.
Check the Throttle Body: Inspect and clean the throttle body and throttle position sensor.
Test the Idle Control Unit: Ensure that the idle control unit (ICU) is functioning correctly.
Check Fuel System: Examine the fuel filter, fuel injectors, and fuel pump for blockages or malfunctions.
Evaluate Electrical Components: Evaluate the condition of the spark plugs, ignition wires, distributor cap, and rotor for damage or wear.
Remember to allow time for the readings to stabilize when checking or making adjustments.

    Not bad, but not as good as the response that TinyDolphin gives when using the OpenAI embedding, which, here remember that the source material for the knowledge stack is embedded using the API so it’s not an entirely local process.

    To troubleshoot the idle issue on your 1986 Vanagon, follow these steps based on the provided information:

    1. Check Engine Operating Temperature:
      • Ensure the engine is at operating temperature with an oil temperature of at least 80°C (176°F).
    2. Inspect Throttle Position Switch:
      • Ensure that the throttle position switch is connected and functioning properly.
      • Move the throttle linkage to full throttle position and listen for a clicking noise.
      • Return the throttle linkage to the idle position and listen for a clicking noise.
      • Adjust if necessary to ensure the switch clicks at both full throttle and idle positions.
    3. Idle Stabilization Valve (ISV) Check:
      • Turn off all electrical consumers and ensure the ignition coil is switched on at the connector for the idle stabilization control unit.
    4. If Readings are Off:
      • Refer to “Idle Speed/CO Content – Checking and Adjusting” as indicated on page 37 of your manual.
    5. If Readings are Fixed (Not Fluctuating):
      • Check for a signal from terminal 1 of the ignition coil at the connector for the idle stabilization control unit.
      • Use the US 1115 LED tester between terminals 5 and 17 of the connector to ensure proper signal.

    By following these steps, you should be able to identify and potentially correct the idle issue on your 1986 Vanagon.

    So the weak link here really seems to be the local embedding process. This embedding process is still opaque to me and there are many parameters that may improve the quality so that is going to be my next step here.
