They have a megashader with an entire 64 bit float emulation library, which takes a good while to compile.

Their shader is doing software 64 bit float emulation, including trignometric functions. That city graphic is really precise. (edit: it looks like the 64 bit math is used only for the map projection part of the shader... so it's not

The LLVM IR doesn't define an ABI - in particular, most of the ABI is already "burned in" at the point where LLVM IR exists.

The DAO. It was, indeed, pretty disruptive.

I used to have a couple I would attach to coworker's computers randomly to confuse them. Doesn't work anymore because no one uses desktops with PS/2 ports...

It will save you, because while your compromised machine could change the transaction before it's signed, the hardware wallet will display the transaction and the change will be visible. Even if the user fails to properly check the des

I hit this issue two years ago while writing a "hardware wallet" that ran on Rockbox (so it could be sued with a Sansa Clip or other commodity hardware). It put me off finishing the project due to the complexity needed to work aro

WebRTC is the HTML5 equivalent of RTSP (they are both based on RTP). You can use Janus to translate between the two - feed RTSP into Janus and it'll apply the necessary encryption and do the necessary firewall hole-punching to make it

Side note: "hard fork" has a special meaning for Bitcoin and derivatives, but no meaning for a software fork. I've seen that phrase used several times in the comments though - is this a new trend?

You will also need a license from MPEG-LA: http://www.mpegla.com/main/programs/HEVC/Documents/HEVCweb.p... And also one from Technicolor, whose licensing fees are undisclosed.

Afaik every phone made in the last year has a VP9 hardware decoder.

Do you have details on the encoding? I'm a bit suspicious of it being actually ultrasonic (device microphones often filter at 20khz or below) - seems more likely it would be audible spectrum noise with a ton of FEC.

Image and video codecs don't actually use the fourier transform as presented in the article, they use the DCT. Check out the example section on Wikipedia: https://en.wikipedia.org/wiki/Discrete_cosine_transform Th

Most codecs split the image into prediction blocks (for example, 16x16 for MPEG-2, or from 4x4 to 64x64 for VP9). Each of these blocks has its own motion vector. All of the transformations you mentioned look like a translation if you look a

Nope, it's a clientside "polyfill of <video>", basically. Try out the demo in the page - it does all playback in Javascript and WebGL.

Many solar cell installations use maximum power point trackers with an internal high voltage DC bus - you could presumably tap that and distribute it directly throughout the house (often it's also directly attached to lead-acid battery

You can do it live, there is a device node you cat the bitstream to. You will also need coordination with any drivers for that hardware, of course.

libW in this case would pretty clearly be a derived work in this case, so would also need to carry the GPL license.

What previous "bad IPC" mechanisms were integrated into mainline Linux? Only one I can think of is sysv shared memory.

... that's pretty much the point of ioctl - a syscall multiplexer in the context of a fd. 9 is pretty low - check out /dev/cdrom or /dev/dri/* if you want to see a lot.

Bear in mind that owners of either coin are financially motivated to promote it vs the alternative, as its value is driven by demand. Expect to disregard the majority of comments about altcoins (Monero and ZCash are among the few doing anyt

I don't think the variable-length encoding itself is the author's concern, it's adding additional filters later without an overall version number. Unlike long file names in FAT32, adding additional filters is not backwards co

Perhaps an easier example is Janus, such as their 2-way demo that forwards all media packets through the Janus server: https://janus.conf.meetecho.com/videocalltest.html Or the more complex demo, for a video conference wher

In fact, you can easily add a streaming server in the middle (and many-participant WebRTC servers do exactly this), it's just that you can't have it happen unintentionally.

Yeah, it seems to be a pretty high-end but otherwise standard smartphone camera. Almost all of the features they advertise are of the software or related peripherals, but not of the lens or sensor itself.

It is possible that the researcher also secretly shared the results with Google, but then nothing happened?
