Start with MongoDB

MongoDB is hot these days.  So, it never bothers to give a try.

Quick start: http://docs.mongodb.org/master/tutorial/install-mongodb-on-debian-or-ubuntu-linux/

Amazon AWS

I’m trying Amazon EC2 as VM.  It’s the very first I heard about it and tried a little bit.  Basically, it’s just exactly like remote server in the school professor set up everything for you and gives you an account.  That’s what we called ‘cloud’?

The setup instruction is :https://docs.google.com/document/pub?id=1yqdM0kzx-iiD4tvyyIne3KfpntK7TcwMJnxcVWqV2iE

Maybe, you wanna exploit more: http://aws.amazon.com/developertools/351

Install Java in Ubuntu

Installing Oracle Java SDK in Ubuntu is not easy as before because not so long ago Oracle decided to change licensing of Java. Which in the long run will hurt only users. Distributions can no longer make automated installs of Oracle Java, users are required to agree with the license displayed on Oracle’s web site.  I googled two way to install it:

Instructions were written on x64 so if you are running 32bit version of Ubuntu, adjust accordingly. First, you will need Oracle Java SDK which you can get here. Extract it in /usr/lib/jvm directory and give the newly created directory a pretty name and a symlink:

$ cd /usr/lib/jvm/
$ sudo tar -xvzf ~/jdk-7-linux-x64.tar.gz
$ sudo mv jdk1.7.0 java-7-oracle
$ sudo ln -s java-7-oracle java-1.7.0-oracle

Now, create a file .java-1.7.0-oracle.jinfo in /usr/lib/jvm with the following contents:

alias=java-7-oracle
priority=100
section=non-free

After you created the file, you will need to tell the system about your new Java. For this you will have to use a bunch of pretty cryptic commands.

At last you can use update-alternatives to select newly installed Java SDK. When you run the first command, make sure that you select the newly installed Java SDK. At the end, don’t forget to exit from the root shell.

# update-alternatives --config java
# update-java-alternatives --set java-1.7.0-oracle
# exit
sudo apt-get install python-software-properties
sudo add-apt-repository ppa:ferramroberto/java
sudo apt-get update
sudo apt-get install sun-java6-jdk sun-java6-plugin

You may want to also add the following

sudo update-alternatives --config java

You should get the following

  Selection    Path                                      Priority   Status

  2            /usr/lib/jvm/java-6-sun/jre/bin/java       63        manual mode

Press enter to keep the current choice[*], or type selection number: 2

Select (2) and press enter

Now running:

java -version

Returns:

java version "1.6.0_26"

Term

3GPP was originally the standards partnership evolving GSM systems towards the 3rd Generation. However, since the completion of the first LTE and the Evolved Packet Core specifications, 3GPP has become the focal point for mobile systems beyond 3G.

ITU Radiocommunication Sector (ITU-R) is one of the three sectors (divisions or units) of the International Telecommunication Union (ITU) and is responsible for radio communication, whose role is to manage the international radio-frequency spectrum and satellite orbit resources and to develop standards for radiocommunication systems with the objective of ensuring the effective use of the spectrum.

International Mobile Telecommunications-Advanced (IMT-Advanced) are requirements issued by the ITU-R of the International Telecommunication Union (ITU) in 2008 for what is marketed as 4Gmobile phone and Internet access service.

GSM (Global System for Mobile Communications), is a standard set developed by the European Telecommunications Standards Institute (ETSI) to describe technologies for second generation (2G) digital cellular networks. Developed as a replacement for first generation (1G) analog cellular networks, the GSM standard originally described a digital, circuit switched network optimized for full duplex voice telephony. The standard was expanded over time to include first circuit switched data transport, then packet data transport via GPRS (General Packet Radio services). Packet data transmission speeds were later increased via EDGE(Enhanced Data rates for GSM Evolution) referred as EGPRS. The GSM standard is more improved after the development of third generation (3G) UMTS standard developed by the 3GPP. GSM networks will evolve further as they begin to incorporate fourth generation (4G) LTE Advanced standards.

Universal Mobile Telecommunications System (UMTS) is a third generation mobile cellular technology for networks based on the GSM standard. Developed by the 3GPP (3rd Generation Partnership Project), UMTS is a component of the International Telecommunications Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology. UMTS employs Wideband Code Division Multiple Access (W-CDMA) radio access technology to offer greater spectral efficiency and bandwidth to mobile network operators. UMTS specifies a complete network system, covering the radio access network (UMTS Terrestrial Radio Access Network, or UTRAN), the core network (Mobile Application Part, or MAP) and the authentication of users via SIM cards.

The European Telecommunications Standards Institute (ETSI) is an independent, non-profit, standardization organization in the telecommunicationsindustry (equipment makers and network operators) in Europe, with worldwide projection. ETSI has been successful in standardizing the Low Power Radio, Short Range Device, GSM cell phone system and the TETRA professional mobile radio system.

High Speed Packet Access (HSPA)[1] is an amalgamation of two mobile telephony protocols, High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA), that extends and improves the performance of existing WCDMA protocols.

Alien

Alien is a program that converts between Red Hat rpm, Debian deb, Stampede slp, Slackware tgz, and Solaris pkg file formats. If you want to use a package from another linux distribution than the one you have installed on your system, you can use alien to convert it to your preferred package format and install it. It also supports LSB packages.

Run this command to install alien and other necessary packages:

sudo apt-get install alien dpkg-dev debhelper build-essential

To convert a package from rpm to debian format, use this command syntax. The sudo may not be necessary, but we’ll include it just in case.

sudo alien packagename.rpm

To install the package, you’ll use the dpkg utility, which is the internal package management tool behind debian and Ubuntu.

sudo dpkg -i packagename.deb

SQA

SQA大致上可分3大組

1.SIT Team: 負責系統整合測試, 也就是雜七雜八的都包了

每個軟體版本我們會去做BAT(Basic Acceptace Test)來判斷這個軟體版本是不是可被整個PROJECT各單位使用

也會做很多不同fUNCTION EX: WIFI, BT等的functional, IOT, stability, performance等的測試

2.CE Team: Carrier Engagement

負責LAB實驗室認證及實網Field Trial test，主要跑底層Protocol的測項

3.Logo Team: 負責Logo相關的Certification

ex: Wi-Fi, BT, MS, Android相關Logo的取得等

大致上分這三個Team，另外量產前也要負責release軟體給產線的工作

簡單來講是這樣的模式
