My big gripe with Sony headphones is the touch interface. It's just not very good, triggers accidentally and is awkward to use intentionally (and gloves are out). I wish I'd bought the equivalent Bose headset (they cost the same)

This is partly a labour law thing. The EU benefits from freedom of movement and work, so people can apply to different countries without worrying about immigration. Residents outside the EU (third countries) may have to prove why they'

Google Zurich is the European research hub. They do a lot of very cool stuff, particularly mobile deep learning. Salaries are commensurate with the Bay Area, but Switzerland is as if not more expensive (though arguably higher standard of li

Photogrammetry is extremely compute-intensive, but it is embarassingly parallel. You need to compute feature points in all your images (which is generally fairly fast, even if you use something like SIFT). Then you have to match features wh

You can buy a FLIR Boson at 640x512 for that price. The cost of thermal cameras is roughly linear with the number of pixels. I realise that's not cheap, but you can get double the resolution (e.g. 4x pixels) for the same money.

It's expensive because of economy of scale. EZ Flash sells way more devices. However, it's more power efficient than the EZ Flash I believe due to better use of the FPGA. The Omega looks good though, and it also supports save stat

I strongly recommend upgrading your GBA if you still have it - you can get an IPS replacement screen (bare minimum, it's an enormous improvement), USB-C Lipo battery, new shells/buttons, louder speaker, etc. I think it costs aro

Thorlabs don't make their own cameras by the way, they're white-label IDS Imaging products (at least they used to be). Most of these [machine vision] cameras will communicate using genicam, so you can use libraries like Aravis and

It depends on the language pairings. Take a look at Don Quixote in English and Spanish, they're very comparable at the sentence level (at least this translation). Also if course it depends on the artistic license of the translation. Ma

In theory you could do this with books? Sentences in translations should still be the same, and you could add some heuristics to identify paragraphs, quote marks, etc. You might be wrong occasionally, but doing the extraction per chapter or

If your pipeline depends on running inference on a single frame at a time, for example some kind of control loop, then you need to be a bit careful about how you measure speed; you have to use the effective time per batch (ie batch size 1),

I would have thought that the max SPI speed on the Pi is probably faster than your peripherals can deal with. Your bigger problem is system interrupts which might cause discontinuous capture. The speed is derived from the core clock which c

Perhaps it reduces interference in the same cable if the USB Vbus is noisy? It might also be just to suppress radiation from the cable which could affect other devices. Though I'm not sure you really need it on USB2. I've built cu

There is a base circadian period which is roughly the length of a day, but it varies between individuals. If you put people in caves with no light at all, they'll still naturally fall into a sleep/wake cycle around 24 hours (it te
