Working on modifications, mini-challenges or new levels?

Got a question or comment about the app?

You’re in the right place.

Post your questions (and answers) right here and we’ll help you as best we can.

To create Dev Story/*HACK THE CODE*/ we used the Intel XDK and Crosswalk with a couple of open-source javascript libraries.

Hadoop Hbase 升级

Hadoop HDFS 与Hbase升级笔记

由于之前使用了hadoop1.0.2,hbase 使用的是hbase-0.92.1 但是一次事故导致元数据丢失,且修复元数据的类本身有BUG
所以摆在眼前的只有两条路:
1、修改hbase源码重新编译 hbase 修复BUG
2、升级到下一个版本,且这个版本已经修复了此BUG 从release node中看到 0.92.2及以后版本均修复了此bug
  所以决定升级到最新的稳定版 hbase-0.94.3 而此版本的hbase 和hadoop-1.0.4 的兼容性最好,所以hadoop 连带升级到hadoop-1.0.4

1. Hadoop升级步骤:
 (1)停止集群上的所有MR任务,包括Hbase(如果Hbase在使用中,先停掉,接着是zookeeper)
 (2)停止DFS(1、2两步也可以在hbase和zookeeper关闭后使用stop-all.sh脚本直接关闭)
 (3)删除临时数据,即在core-site.xml中设置的hadoop.tmp.dir的value所文件目录下的文件
 (4)备份HDFS元数据

java socket 多线程网络传输多个文件

     由于需要研究了下用 java socket 传输文件,由于需要传输多个文件,因此,采用了多线程设计。客户端每个线程创建一个 socket 连接,每个 socket 连接负责传输一个文件,服务端的ServerSocket每次 accept 一个 socket 连接,创建一个线程用于接收客户端传来的文件。

Intel® IoT Roadshow Taipei, Taiwan

We had an Intel IoT roadshow at Taipei on 16th and 17th of May 2015 at CLBC flagship.

128 attendees developed 32 working prototypes in 48 hours. We provided our IoT developer kit to each attendee which had an Intel Edison board, Arduino expansion board and many basic sensors. People also got their own sensors to work with Edison.

We gave a session to the participants on how to get started with Edison and an overview of all the supported software tools and SDK to get their work going.

Participe do Intel IoT Roadshow 2015 - Sao Paulo

Nos dias 19 e 20 de Junho, vamos realizar em São Paulo, no Insper, a edição brasileira do Intel IoT Roadshow 2015, uma série de 20 eventos que serão realizados em diversos países, divulgando o kit para desenvolvimento de IoT da Intel.

Com o formato de hackathon, iremos utilizar no evento a placa Intel Edison e o Grove Starter Kit, em conjunto com o kit para desenvolvimento de IoT da Intel, um conjunto de softwares e bibliotecas Open Source que permitem o desenvolvimento de soluções utilizando a IDE do Arduino, Javascript (node.js), C/C++, Python e Scratch (via Wyliodrin).

How to correct setting AVD

Dear Guys,

Does anyone know how to set AVD correctly. Let the front camera on your laptop can be like a real machine front camera running at the same

application? I tried to change but the results are not good. Hope help me to resolve the issue by intel developers,Thanks a lot.

Communicate to Arduino code with your Android* Phone by Bluetooth Serial Port Profile (SPP) on Intel® Edison

Introduction:

In Arduino environment, it's convenient to access BT SPP like a serial port and react to the command string sent from the BT serial port. Many Arduino projects have utilized this way to allow remote control for their projects. In the past, you'll need additional BT shield or BT kit to archive it on Intel® Galileo. Now, since we have built-in BT support on Intel® Edison, you can use Edison module with Arduino breakout board to do it. NO additional BT shield is required!
