WebUSB is so great.

I can ship a cross-platform application that accesses a hardware device without having to deal with all the platform specifics, and with decent sandboxing of my driver.

I think one way to make it more "secure" against unwitting users would be to only support WebUSB for devices that have a WebUSB descriptor - would allow "origin" checking.

For me PulseView unfortunately has been very buggy and I never really got it to work (neither with an old Saleae 8, a new Saleae Pro 16, or an FX2 clone) well and without constant crashes.

I tried on Linux & mac, but never could get it to run well. I'd be super curious to chat with someone who had a different experience on what you've been doing differently from me!

I love the idea of Sigrok, so would love to get it to work (well) for me

Couple of things I learned from helping some blind people:

- All used iPhones (Check out https://www.apple.com/accessibility/vision/ )

- Disable passcode if he's okay with it

- Enable VoiceOver (Settings -> Accessibility) and learn how to enable/disable it (triple-tap the side button. Might be difficult for elderly) - Apple video on it: https://www.youtube.com/watch?v=qDm7GiKra28

- Having a learning partner really helps the blind person. Try to learn to use a phone blind with him, it will allow you to help debug his (most definitely occuring) issues

- Watch some videos on how blind people use the iPhone, lots of tips there. For example Molly Burke, or even simple ones like this one: https://www.youtube.com/watch?v=3FVjLXIaBC4

- For elderly, an iPad is really nice. Especially as dexterity gets worse it's easier to use blindly. Also usability between iPhone and iPad is almost the same, so easy transition between both (i.e. on the go)

- For movies, check out Greta. It plays the AD in parallel with a movie via the iPhone - so they can watch movies together with the family, without everyone listening to AD https://www.gretaundstarks.de/starks/GretaAndStarks

And bring lots of patience :)

What is really amazing is how fast people tend to improve: VoiceOver lets you adjust the speech speed etcpp, and so it "grows" with you

BladeRF 2.0 micro 8 years ago

Unfortunately the software support for the BladeRF 2.0 micro is not yet very mature - the official installation instructions do not work (don't install udev rules etc).

I would recommend waiting a couple of months and see how the ecosystem develops.

I feel like this demo is not really good. A video where a (real) face is learned in and then the mask is used to unlock would be good, this could just show that the mask is learned into FaceID.

Actually, from an embedded perspective, almost all SD cards do not guarantee that they don't corrupt when you kill power during a write. This is because of the internal workings of SD cards and completely unrelated to shoddy engineering/programming.

Afaik quite some of the major apps were leaving it in the last years (Sketch comes to mind), but might just be my filter bubble.. Would be interesting to hear from some Mac OS devs

It is reasonable to keep up-to-date with Mac hardware if you use computers a lot. If things go wrong, it is far easier to take the laptop to the Genius Bar than options for other laptops.

To be honest, the best service I so far was with my Lenovo machines.. Next-(work-)day technician on site, whether I'm at a customer or at home.

Now with my MacBook Pro with Apple Care they have to send it in to replace the screen.. (According to the Apple Store personell here at least)

Works quite well (on iOS), really good work! Here is a small issue I experience on a lot of mobile sites with embedded maps and also on yours:

If I zoom the page outside of the map and then scroll so that the map fills the full screen there is no way to zoom out/get away from the map again. You will just scroll and zoom the map and eventually will have to reload the page. It also allows to scroll far out of bounds of the world which can be a bit confusing.
