Introduzione allo sviluppo di applicazioni mobile cross-platform

Lo sapevi che si possono sviluppare applicazioni mobile cross-platform di elevata qualità utilizzando solo HTML, CSS e JavaScript ? Ok, domanda banale, molti oramai lo sanno ma tantissimi developers non ne sono ancora al corrente o, sono ancora scettici o comunque non ancora del tutto convinti riguardo l’uso di queste tecnologie in ambito mobile; proprio per quest’ultimo motivo ho deciso di scrivere una serie di blog posts ed alcuni articoli tecnici che verranno linkati man mano in calce a questo blog post per, mostrarti come con l’uso delle tue skills in ambito web e, con l’IDE Intel XDK si possano sviluppare applicazioni mobile di elevata qualità in maniera veloce ed infine estremamente efficiente.

Exposing processor features to dynamic languages

It always causes me exquisite pain to see someone laboriously copying down a long number from their computer screen, just to type it in to another window or application. Doesn't it for you?

After all, doesn't everyone know about the cut-copy-paste keys? I'm talking about selecting text with your cursor and using control-C for copy and control-V for paste.

Diagnostic 3180: unrecognized OpenMP #pragma

The test code bellow worked with Intel Composer 2013 but not with SP1 Update 5,
and gives me "Diagnostic 3180: unrecognized OpenMP #pragma".
Thanks in advance.

// OpenMPTest.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <map>
#include <omp.h>

int _tmain(int argc, _TCHAR* argv[])
{
	std::map<int, int> box;
	box[0] = 0;
	box[1] = 0;
	box[2] = 0;

#pragma omp parallel for
	for (auto iter = box.begin(); iter != box.end(); ++iter) {
		(*iter).second = rand();
	}
	return 0;
}

 

Dynamic Languages take over the internet

What would happen if you were hauling a trailer down the road, and suddenly you realized that the trailer you thought you were pulling passes you on the highway. (Which I guess can actually happen, I just saw a video capture of this exact disaster, happening to a trucker). You might not feel kind of blind-sided!

This is kind of the way I feel when a technology trend sneaks up on me and suddenly I feel like I'm way behind the curve.

Innovation Think!

I have been hosting a program, started in March of 2015, called “Innovation Think” with the intent to get people exposed to technology that stimulates innovation either directly or through the exercising of the creative mind.

OpenMP slower than serial codes

Hi,

I am trying to do the parallelization of a serial preconditioned conjugate gradient solver codes for 3D fire simulation using OpenMP (Intel compiler). But the performance seems not to be improved.

The grid dimension is 79x81x79 and the solver can converge after 565 iterations. The serial codes cost 3.39 seconds and the OpenMP version needs 3.86 seconds on Intel i7 2600.

Please help me to check  the codes. Thanks a lot.

Meshcentral - Now with integrated Manageabiltiy Commander Web Edition

The new Manageability Commander code base offers many benefits. For example, the hardware KVM feature in Meshcentral used to not support compression, and so, was very slow. The new viewer supports full ZRLE8 and ZRLE16 tile compression allowing for much better KVM performance over the Internet. All of the WSMAN/KVM/SOL smarts is built in JavaScript and runs in the browser, greatly simplifying the server that focuses on connection relay. Administrators can now manage Intel AMT user accounts, event log and more… as Manageability Commander evolves, new versions of the code will be integrated into Meshcentral, so the console will get better over time.

Portación de aplicaciones de Chrome* a plataformas móviles con Crosswalk y Chrome Apps for Mobile

Las aplicaciones de Chrome funcionan en todas las plataformas para las que existe una versión actual de Chrome, entre las que quedan abarcadas casi todas las plataformas de escritorio; este no es el caso de las plataformas de dispositivos móviles, que a menudo usan un modelo diferente de hosting de aplicaciones y tienen sus propias tiendas digitales. Como las aplicaciones de Chrome se crean a partir de tecnologías basadas en el navegador, técnicamente podríamos reempaquetarlas para móviles con Apache Cordova* y enviarlas a las tiendas.
