Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      I am not familiar with the details, but I've been told that in this case ITAR is involved. Not sure if that's a better or worse reason than "Apple screws with supply chains"

      Replying to @rqou_

      Indeed, it seems plausible that there's no demand for the ultra-low-quality sensors (thus them being overpriced), and that the medium- to high-quality ones only comply with ITAR when they're integrated in a product that restricts framerate in firmware...

      Replying to @RichFelker @rqou_

      But that's utterly idiotic because anyone wanting to make weapons with the high-quality ones would just buy a cheap consumer product containing the sensor and rip it out.

      I heard that some of these actually perform the limiting in the firmware deeply embedded in the sensor itself, but I have no further details. @azonenberg do you have more information?

      Replying to @rqou_ @RichFelker

      Nope. My only thermal gear is unlocked 60fps and is very much export-controlled. I don't think the Boson 320 core is ITAR though, pretty sure it's considered dual-use and on the CCL instead.

      According to FLIR's website FAQ for the Tau2 and Quark sensors, the <9 FPS versions are still natively 30 FPS at both the sensor and host side interfaces, however the core discards 3 out of every 4 frames and replaces them with copies of the previous frame.

      Replying to @azonenberg @rqou_ @RichFelker

      So they're drop-in compatible with the full-rate sensor (since they spit out 30 fields per second) but comply with export restrictions regarding <9 FPS effective video output (since only ~8.3 frames per secon contain new data)

      I came across a Chinese manufactured TI camera for iphone/Android the other day that was hires and hi frame rate...and not ITAR controlled because it wasn't US sourced... wish I could find the brochure now...

      Well.... this is the company's site... I can't see the hi-res phone add-on camera, but the lo res one is here http://www.magnity.com.cn/product/id/7.html … but 17um 640x480 25Hz here http://www.magnity.com.cn/product/id/8.html … and 14um 1024x768 25Hz here http://www.magnity.com.cn/product/id/1.html … These are above ITAR limits

      Nice. WIsh they had something more compact/practical for attachment to phone/tablet or embedded.
