Apple does not claim ownership of your output that is done on your own time, with your own resources, as long as it doesn't relate to work you're doing at Apple. I recently signed an employment agreement with them. It was the most

In my opinion, Nvidia took over the market because they picked up the pieces from SGI when the company failed. SGI had all of the engineering talent to make a world class 3D chip for PC gaming but SGI management was too busy clinging to the

RISC-V is not that close to ARM, and it's not mature enough for Apple to move to it. RISC-V is interesting but I think we'll see it adopted in commercial embedded systems first.

The Amiga was a huge leap forward once ARexx became popular. It was an easy to use scripting language that allowed you to receive events and instruct the OS and applications to run commands and functions. After the release of AmigaOS 2 it b

I recently ordered two Microsoft Signature Edition laptops from the Microsoft store. Both of them were great out of the box. No crapware at all.

Von Neumann Architecture has been dead and buried for 20 years. We only imagine our x86 is Von Neumann because there is coherence between the instruction and data caches. Every modern machine is a Modified Harvard Architecture. http:/

X86 system management mode is not something you can turn off. It is there to protect motherboard firmware code that runs on the CPU. That code does things like emulate PS/2 mouse and keyboard. See chapter 34 in [1]. SMM is not for ente

A hypervisor runs below ring 0 and system management mode runs below that.

VT-x allows guest operating systems to run in Ring 0. If this exploit works then a guest OS can exploit the hypervisor.

Altera is claiming they will have >10 TFLOPS next year. They designed floating point DSP blocks in the Arria 10 and Stratix 10 (due out 2016Q1). https://www.altera.com/content/dam/altera-www/global/en_

PTX is a virtual ISA that is not the same as the machine code that runs on the device. In his Introduction[1] wiki page, he says that he studied sgemm implementations and came to the conclusion that NVidia is not using PTX, but an assembler

It would be prohibitively slow. Division and modulus are the slowest integer operations.

I know this code is just an example, but it seems like it's entirely backwards. The "bad" code at the beginning is immediately clear in what it's doing, but the refactored code is significantly longer and hard to underst

Digital designers still use it. I'd bet that most of the silicon in your computer was designed with a lot of TCL involved.

Logic circuits are frequently modeled with four states: 0, 1, X, and Z. X means unknown, or "don't care" in some contexts. Z usually means high impedance.

No, they don't always achieve the same results but there is a lot of engineering dedicated to correct the errors. You can find academic papers on the subject of GPGPU soft errors around 5 years ago when people started doing general pur

There's only one easy way to cancel service with a company like Comcast. You have to lie and tell them you're moving to a city that they don't serve. They don't transfer you to customer retention and you'll be off t

They really do care if you register. If you don't register by 26 and decide to go to college later, you'll lose a significant amount of financial aid offered to independent students. There's no way to register after 26, so yo

I think your equation is modeling an exact savings of 300 for sending 1000 pieces of mail. The discount is 10% for sending 1000 pieces. Mine is simply comparing the cost of sending n pieces of mail at $3 each to 90% of the sum of n pieces a

It's even less than that. The equation that describes the decision to send envelopes is: 0.9(3n + 1000 - n) < 3n Which is the same as n > 750.

My first FPGA was a cheap Lattice kit and I never fully wrapped my head around their toolchain (Diamond). It has everything you need but the workflow and UI made it hard for me as a beginner. I also found the documentation and tutorials to

I don't know what he used, but its probably based on the model specific registers for performance counters. See Chapter 18 of the Intel 64 and IA-32 Architectures Software Developer's Manual.
