  • A Statement From Linda Ronstadt

    Sept. II, 2024

    San Francisco

    Donald Trump is holding a rally on Thursday in a rented hall in my hometown, Tucson. I would prefer to ignore that sad fact. But since the building has my name on it. I need to say something.

    It saddens me to see the former President bring his hate show to Tucson, a town with deep Mexican-American roots and a joyful. tolerant spirit.

    I don’t just deplore his toxic politics, his hatred of women. immigrants and people of color, his criminality, dishonesty and ignorance although there’s that.

    For me it comes down to this: In Nogales and across the southern border, the Trump Administration systematically ripped apart migrant families seeking asylum. Family separation made orphans of thousands of little children and babies, and brutalized their desperate mothers and fathers. It remains a humanitarian catastrophe that Physicians for Human Rights said met the criteria for torture.

    There is no forgiving or forgetting the heartbreak he caused.

    Trump first ran for President warning about rapists coming in from Mexico. I’m worried about keeping the rapist out of the White House.

    P.S. to J.D. Vance:

    I raised two adopted children in Tucson as a single mom. They are both grown and living in their own houses. I live with a cat. Am I half a childless cat lady because I’m unmarried and didn’t give birth to my kids? Call me what you want, but this cat lady will be voting proudly in November for Kamala Harris and Tim Walz.

  • Multiple camera angles are used for two reasons:

    1. Added visual interest. People tend to want variety and colour and movement offered by different views can provide that. This is the obvious reason it’s being used.
    2. Ability to edit without it being obvious. Often a presenter will require multiple takes to “get it right”. If you edit in the take, the picture “jumps” because humans move around. If you have multiple cameras you can edit and switch cameras without it looking like an edit. If you then also look at a different camera when you make a mistake, you can keep recording and fix it when you edit it together.










  • I suspect that your success rate will be very low. Bone conduction microphones might be your best bet.

    Fundamentally a microphone doesn’t know the difference between “good” sound and “bad” sound.

    Most noise cancelling solutions are based around the idea that nearby sound is good and distant sound is bad.

    It differentiate between the two by using the fact that it takes time for sound to travel.

    If you have two identical microphones, you can set them up so that you talk directly into one, but not the other.

    Any environmental sounds are picked up by both and used to cancel it - sometimes in software, other times just by reversing the microphone polarity.

    Bone conduction microphones get their signal from physical contact with the audio source, your body.

    Source: I’ve done a little bit of audio recording over the years in and outside of studios. My information might be incomplete and out of date. YMMV.



  • Generally laziness helps.

    If you host a system, then you have to dedicate resources to maintaining it, which quickly escalates to lack of interest.

    If you pay someone to host it, you get to spend your energy on things that you’re interested in.

    If you can find people to pay you for things that you’re interested in, but they just want fixed, you have a business.

    So, be conservative in what you host and frivolous in what you outsource.

    Note that this says nothing about FOSS. since that’s about a related but different concepts.

    From a FOSS perspective, be frivolous (as in, do lots) in your bug reports and patches, be conservative in which projects you own.
