Well, the TREZOR is already a dedicated "smart card". If you ran the same code on a smart card, you'd have the same side channel attacks.

Darktable already has a database of base curves and noise profiles for many cameras. I don't know what else you really need?

The good news is that presumably the introduction of this bug means that they needlessly rewrote the RTC for this generation of chips, which means they might meaninglessly rewrite it again and the bug will be fixed!

This has existed for a long time, see the Linux kernel's mtd infrastructure, and the filesystems designed to run on top of it (jffs, yaffs). It used to be used in a lot of embedded devices before eMMC became cheap, and is still used in

Logging to poorly specified Flash storage is the real problem. They were likely using a cheap eMMC flash, which are notorious for having extremely poor write leveling. Unfortunately the jump to good flash is quite expensive, and often hard

To be fair, with any amount of actual testing of the hardware IP before production, this would have been caught, it's a pretty bad bug. Or Rockchip could have simply implemented a linear seconds counter, which would have worked fine an

It's still a security win, because the CDM sandbox is allowed to do substantially less than the Flash sandbox. Flash can access your webcam, filesystem, make any network connection, etc. The CDM only decrypts and decodes frames.

Not any easier than other browsers, such as Chrome's Widevine, for example.

They still do it. For some Bluetooth device classes, you must get your device signed by Apple and use certain chips. One product I worked on had a dual Bluetooth and BLE stack - Bluetooth for Android, and BLE to circumvent the Apple limitat

I do most of my music discovery on Soundcloud these days. That plus Bandcamp covers most of my needs. Many artists are starting collectives which publish albums with a variety of artists approximately monthly, which also is great for discov

A bandcamp for books? This must exist already, but nothing comes to mind...

I generally end up using an online tool [1] for high pin count parts. It's not the best though, someday I will write something better. BTW, in most professional contexts, parts are all created by the engineer - vendor part libraries ar

I recently switched from Altium Designer to KiCad, because while I do have access to Altium Designer, I wanted it to be more accessible. KiCad is quite good, once you get the hang of it and the differences between Altium. I was able to put

Well, from a development perspective a SD card is a lot nicer because you can pop it out and write it easily if you brick it, whereas eMMC requires fastboot or weird OEM loaders that only run on 32 bit XP on Tuesdays. Also, eMMC's bus

The networking on the other Pis is attached via USB. It's a very easy and obvious thing to drop.

It probably won't blow anything up, but the active PFC might not be very happy as it tries to track the AC waveform to control the current draw. It might just not work. You'd be better off getting one of the cheaper clone adapters

>hardware HEVC support, so we suggest to use it if patents are an issue. This will not save you from the HEVC Advance content fees, which are a percentage of your website's total revenue related to the images.

You will need at least two licenses, one from MPEG-LA and one from HEVC Advance. MPEG-LA publishes a list of patents so you can see if there are any covering your country. In addition, HEVC Advance also licenses based on the total revenue y

Using the hardware decoder requires creating a new decoder for each size of image you're decoding, and round-trip latency to get the frame back and do compositing on the web page. In addition, most hardware decoders have a limited numb

They absolutely can. My Sony Xperia Z3 (benchmarks worse than the new Apple chips) can play 1080p VP9 fine with software decoding.

It's buildable and works, but you obviously could never submit it to the App Store.

XP is still supported via POSReady 2009. It's still got 5 years of life left in it for updates.

VP9 software decoder implementations are also far ahead. Both ffvp9 and libvpx are faster than current hevc implementations with one core, and ffvp9 also scales well to multiple cores. https://blogs.gnome.org/rbultje/20

Well, one could argue that just sending bits cannot be in violation of any patents, though I'm not aware of any cases where this has been tested in court. If you have any encoding / decoding anywhere in your company though, then y

Yeah, those are the only options. The second option is what Blu-Ray and EME currently do, for example. But yeah, basically no one is going to use this ever.

Yes it would - but that's how all DRM systems work, plus an attempt to make the image unreadable to "unauthorized" JPEG implementations.

The Ethernet phy is actually pretty expensive, especially compared to USB 1.0. The isolation transformers alone are $1. Of course you could skip the isolation like some backplanes do. The ID assignment for USB is pretty awful and so is the
