My application to be one of the exclusive beta users for the Google Android App Inventor has been accepted last month. Today while at the office, I was able to install the Google Android App Inventor on Ubuntu Linux Netbook Remix 10.04. This includes the Android Emulator and the web based App Inventor. Instructions for installing App Inventor can be found here : http://appinventor.googlelabs.com/learn/setup/index.html . If you do not have an Android phone, then use the Android Emulator which is located on your computer at /usr/google/appinventor-extras/commands-for-Appinventor/run-emulator .

Earlier this morning I subscribed to the Maxis Broadband Laptop bundle which features the Lenovo Thinkpad X100e subnotebook bundled with a 1GB broadband package and Huawei E1552 modem. The Thinkpad has an AMD Neo processor, 2GB RAM and 11.6 inch display. The main reason for upgrading from my existing Acer Aspire One with Intel Atom N270 processor, 1GB RAM and 8.9 inch display. The Thinkpad will arrive in 2 weeks time, but received the Huawei E1552 modem on registration.
Two months back, I registered for the Maxis 3GB package with Huawei E1762 which replaced my TM Streamyx 1Mbps package at home. The reason being lower price and mobility for the family. This was very easy to use, just stick it into USB port, then just follow the instructions to get connected. The E1762 modem is capable of speeds up to 7.2Mbps.
But with the Huawei E1552 modem, there is an additional step to do, which is to install usb-modeswitch. This package will enable to switch from a pendrive storage device to the 3G USB modem device. After that just stick the modem to your USB port and follow the instructions to get connected. The E1552 modem is capable of speeds up to 3.6Mbps.
And here I am using the E1552 modem to write this blog. I have also bought an Aztech HW550-3G 4-port wireless router to share the E1762 modem among the computers at home. The E1552 modem also works on that router, just stick it in the USB port, then press the connect button on the router.

This will guide the administrator on the procedures for installing and basic configuration of the Palo Business Intelligence Suite on a Ubuntu Linux Server with the Xfce environment. This is a three step process : (1) Install Ubuntu Server; (2) Install Xfce environment; and (3) Install Palo Business Intelligence Suite. In this case, I am installing the software on a server with Quad Core processor, 2GB RAM, a USB port, a CD/DVD drive, and connected to the internet via the local area network (LAN).
This is meant only as a guide (and not a detailed step-by-step process).

This is a very short guide for converting a worksheet in a xls file into a csv file using the open source gnumeric function on the ubuntu linux operating system (this will also work with other gnome based linux distribution like CentOS and Red Hat Enterprise Linux). By default the gnumeric ssconvert function will convert only the first worksheet in a xls file directly into a csv file. To convert any other worksheet, then it is necessary to convert it into txt file first then rename to a csv file.
iskandar@krimnet-netbook:~$ ssconvert -O 'sheet=sheet3 separator=; format=raw eol=windows' SOFTWARE-PROJECT_CASHFLOW.xls SOFTWARE-PROJECT_CASHFLOW3.txt
Using exporter Gnumeric_stf:stf_assistant
iskandar@krimnet-netbook:~$ cp SOFTWARE-PROJECT_CASHFLOW3.txt SOFTWARE-PROJECT_CASHFLOW3.csv
There are several impotant options to note:
- sheet : Name of the workbook sheet to operate on.
- eol : End Of Line convention; how lines are terminated. "unix" for linefeed, "mac" for carriage return; "windows" for carriage return plus linefeed.
- separator : The string used to separate fields. Defaults to space.
- format Acceptable values: "automatic", "raw", or "preserve".

I found another way to convert data in file format into another text format. This time extracting and converting data from http://econ.mpob.gov.my/upk/daily/bh_ffbapr10.htm into a csv (comma-separated value) format. After the data has been converted, then the Palo ETL (extract-transform-load) tool can be used to load into a MySQL database.
I have used jodconverter before but it was not able to convert from htm to csv.
In this method I am using Gnumeric as the converter and it is run on the command line on my Ubuntu Linux Netbook Remix 9.10. I am using the command line, so that it can be used as a batch process. I think the same method can be used on any other Linux distribution which has Gnome desktop environment.
The steps are really very simple (# indicates the command line prompt) :
- Download and install Gnumeric (this is only needed once):
# sudo apt-get install gnumeric
- Download the web page :
# wget http://econ.mpob.gov.my/upk/daily/bh_ffbapr10.htm
- Convert the web page into csv format :
# ssconvert bh_ffbapr10.htm bh_ffbapr10.csv

These are some useful terminal command lines on a Ubuntu computer to connect to a remote Linux server.
# ssh username@12.34.56.789 (to log into the server terminal)
# ssh-keygen -R 12.34.56.789 (to remove the previous RSA key, if the key on the server has changed)

This is an alternative method for converting xls files into csv files using jodconverter and OpenOffice.org as a service. JODconverter is an open source project by Art of Solving Ltd. It requires the Java 1.4 or higher and OpenOffice.org 2.x or 3.x . Click here about installing and using it in Ubuntu 9.10 Netbook Remix.

Here is a quick guide to convert an xls file into csv on Ubuntu. This is useful, when you need to setup a PHP job on a LAMP server to copy a xls file, convert it into csv file, and load the data in the csv file to a MOLAP cube via an ETL job. I am using the perl xls2csv script from Ken Prows and based on the guide by Kieran Barnes.
