Please note that this adapter does NOT use USB3.0 signalling. The only USB signalling going on is USB2.0 to the STM32 micro which seems to configure the actual Display-Port to HDMI-Bridge chip. The "High Speed Lanes" (on which n

When you connect to processes in a pipe such as ... a | b you connect stdout (fd #1) of a to stdin (fd #0) of b. Technically, the shell process will create a pipe, which is two filedescriptors connected back to back. It then will f

I seriously doubt that you could manage to start a fire from the device in question. First the total power of the USB port is ~2,5W on average and given the constraints of the device in terms of size (~ a normal USB thumb drive) you cannot

So they've done their users a favor by providing a consistent experience over all supported platforms? I'd really like to listen in to one of the meetings where decisions to do such kind of blatant platform-abuse is being discusse

We probably agree that any program should be allowed to uniquely identify the files making up the input data. And if Mike would have spotted the (other) more obvious loophole, which is to store input data in only the filenames, he could hav

So, is this a feature that will also appear in Chrome for Android? Is there even an overlap in codebase? [I honestly have no idea] Given that a lot of handsets run ridiculously old Kernels, I assume that this feature will not be usable for

I think one of the first things I'd try when finding such a device on my premises would be to try and login to the self-service portal of the mobile carrier that issued the SIM card. At least in the case of my phone-service provider (I

Depending on how you might want to use the GPIO pins, this is a clear yes, or no... Traditionally, GPIO is somehow a strange beast when integrated as tightly on SOCs like the Broadcom on the Raspberrypi. On one side, it's a pretty dumb

The CTO also claimed that the preinstalled software would be appreciated by users ;-). So better take his words with a grain of salt. ❝In general, we get pretty good feedback from users on what software we pre-install on computers.❞ And yes

Lenovo is a big company, and I'm pretty sure that the department responsible for the preloaded junk is completely separate from the people doing security (or, for that matter, any) testing on their regular drivers and utilities. Unfort

I completely agree. Especially the "streamlined" programming, with the wealth of existing modules for all kind of peripherals make it incredibly easy to prototype most things. In that regard, it's also a very good replacement

That's certainly true if you mix accesses to the same object via volatile and non-volatile pointers. It's even explicitly undefined in the standard. (C99 §6.7.3/5). [while in practice it will work most of the time] But if you

I understand that spawning a shell to do the expansion work probably is a good idea when your goal is to "expand a string like the shell". But my guess is that most users will call wordexp() just to expand a few variables or tilde
