    1. using a reflex camera with a macro objective (Nikon D60 with AF-S Micro NIKKOR 60 mm f/2.8G ED lens)

      I'm curious if there are any drawbacks to training the model using a different camera than the one that is implemented on the OT-2?

    1. [mp4 @ 0x7fe98400dc00] track 1: could not find tag, codec not currently supported in container This means that pcm_mulaw is not allowed in the MP4 output container format. Your choices are: Use a different output container format ffmpeg -i input -codec copy output.mkv Or re-encode the audio ffmpeg -i input -c:v copy -c:a aac output.mp4
    1. IP cameras are of varying quality, some behaving erratically in my experience. Dealing with their RTSP streams requires a dose of fault-tolerance.

    1. Fortunately, the latest-model iPhones feature camera resolutions up to 12 MP; and DSLR cameras often feature 18 MP and up, so you don’t need to be a professional photographer to start with a high-resolution image.
    2. Another name for 7.2 million pixels is 7.2 megapixels (MP); which means you’ll need a minimum 7.2 MP camera to get the best resolution for your 8” x 10” photo.

    1. Found a @facebook #security & #privacy issue. When the app is open it actively uses the camera. I found a bug in the app that lets you see the camera open behind your feed.

      So, Facebook uses your camera even while not active.

    1. first draft could represent a free outpouring of thoughts

      This paragraph outlines a truly augmented way of writing that cannot happen using paper. To me noting on paper has changed purpose. Sometimes it is an echo noting of a quote, a key word, a diagram. It is closer to drawing. But writing as thinking out loud, writing as trying to make sense...that is tech aided. I am sure my mind changes its processimg focus depending on whether I face a screen or a copybook. Just as you shift perspective when you watch through a camera lens to take a good pic...you see more.
