So you could spray sticky rfid chips into an enemy’s hair, undetectable when scanned, and later on you could send the correct signal to identify enemies in the room. Later their hair would be trimmed, leaving no trace.

Aside from the cool privacy aspect, it seems like it would be cool to:

- Attach to insects to later use a detector to find their homes.

- Coat it and eat it to track your digestion.

- Use it in a miniature tornado model or wind tunnel along with a radio spectrograph to have cool visualizations.

- Embed in paintings, 3D models, clothing labels, and more to verify authenticity, get serial numbers, or track inventory.

- Drop a trail of them behind you so others can follow the trail and find you!

Were you the ghost writer for the Headhunters (2011) film ?

Is there a tool that records the timestamp of each executed command during a build, and when you rebuild, it tells you how much time is left instead of "building obj 35 out of 1023" ?

Or (for cmake or ninja) use a CSV that says how long each object takes to build and use it to estimate how much is left ?

The moment they started broadcasting any comment I made on any news story to everybody in my network was when it stopped being useful for me. It's one thing for it to be discoverable if people looked, it's another thing to feature every thought I have prominently in the feed of every person I'm connected to. This was probably a decade ago, and I haven't used it much since then.

That creeps me out, and probably everyone who realizes it. But, and it's not a tongue in cheek question, why not try to use it to your advantage ?

Would I sound better on Zoom if I took out one wireless earbud and spoke into it ?

I guess Signal is pretty safe, but the phone you are using it on is far from safe. Then there is the issue of being able to accidently add unvetted people to the chat. Is that pretty much the size of the technological issue here?
xuhu · 5 months ago
Yes. Then there's the fact that they do this on a daily basis to avoid accountability.

I really don't understand what their endgame is here. AI Search can't be good for their ads business, because by its very nature it bypasses most of the ads. Why would I spend money on Google ads anymore if it doesn't drive traffic to my web site?

"Assembly language of FFmpeg" leads me to think of -filter_complex. It's not for human consumption even once you know many of its gotchas (-ss and keyframes, PTS, labeling and using chain outputs, fading, mixing resolutions etc).

But then again no-one is adjusting timestamps manually in batch scripts, so a high-level script on top of filter_complex doesn't have much purpose.

I don't know about ffslice, but you can get frame-perfect slicing with minimal reencoding via LosslessCut's experimental "smart cut" feature[2] or Smart Media Cutter's[3] smartcut[4].

For some reason, when ffmpeg reencodes from 23.97fps h264 to the same fps and codec, the result looks choppy, like the shutter speed was halved or something. The smart lossless encoding you mentioned helps a lot here.

I don't think there's much hypocrisy in that statement. My interpretation would be something like this:

-- I don't personally think that sex work should be stigmatised

-- Other people do stigmatise it, however.

-- I would like to point out to these people that what I do is analogous to a light version of sex work [and arguably any professional sportsperson sells their body one way or another - so why not this?]

(flashbacks of reading comprehension exams intensify)

He doesn't seem to state his position on whether proper sex work should be stigmatized or not, just that others think it should be.
