You need to ask why the organizers of the Meetup are doing it. If they are corporates, of course they will plug their products. That's the sole reason for them to invest their time. With this in mind, one can easily distinguish betwe

That looks like a dangerous misrepresentation. The original implementation is a bit more involved [1]. Here, the stub entry is not considered at all during the pop. [1] http://www.1024cores.net/home/lock-free-algorithms

Driver support should not be a problem for Google. They can reuse existing drivers with a rump kernel approach [1]. And on mobile devices, many hardware component vendors provide custom drivers (with binary blobs) anyways. It will not be ha

Why use modbus, a protocol that is nothing more than remote access to a bitfield, when you can have OPC UA, a semantic object-database with an (encrypted) meta-object protocol for remote access and real-time notifications. If you look at th

I am sorry if you feel your friend was offended. I did not say all members of elite military units are psychopaths. Some are. And after all I've seen, the concentration seems higher in those military units than in the general populatio

The article basically says that some members of elite military units are psychopaths and acting as such. How ... unsurprising, given their choice of occupation.

That's not difficult at all. You can just say env['f'] = myfunc and the function will be available as f within the environment.

Assuming f is a function, just do local env = {} env['args'] = {...} setfenv(f, env) return f()

Julia and Matlab use the same (Fortran-based) linear algebra codes in the background. I think it is great to see that a port of the Fortran code in Julia is nearly as fast as the Fortran code itself. So you can take Julia and write concise

The book Red Plenty [1] is about why centralized planning didn't work in the USSR. It is not a very technical book. But it shows quite well the reasons why central planning of an economy does not work. Cybersyn is basically the same th

An optimist might read that to mean "Europeans found out that trade deals can be a lot better than what TTIP offered. Such as CETA which the EU is about to close with Canada".

The idea of GuileEmacs is not to move away from the elisp language. The idea is to use an elisp implementation based on the Guile virtual machine. Elisp will not go away. So any arguments for lisp and against scheme are void in this context

You're talking cars. The EU is talking survival. The UK will get indeed a bad deal. And the rest of the EU will stick together even closer. I hear "fiscal harmonization", e.g. common taxation is the new big thing.
