Web scraping is a computer science technique for extracting information and data from web sites. In data mining research scraping and analysing of information is discussed. Practically web scraping is necessary if you want to develop a web application where you want to show customised information from various websites. For this you’ve to first scrap data from the sites and then apply some logic to filter the information.
In my M.Sc study & research me along with my supervisor had written a paper related to Health Informatics that had published in the conference Global Telehealth 2012, Sydney, Australia. The paper had also received one of the best conference paper award in the conference. In my research in MMU, I’m working in health technology and informatics and this is the first time I’ve written an academic paper in my life.
Today my wife and me were going to KL from Melaka by our own car. We started our journey at 12:42PM from Melaka. When we are in 54 KM, 233.5 (Highway mark) distance, suddenly a piece of strong wood or metal type things fly and hit my windscreen. And my windscreen totally cracked and broke, I switched on the left signal and went to the emergency lane. I phoned Plus service (express way service people) number 1800-88-00-00 described my situation, given my car number and the express way position (233.5). They told me they will send service. We are waiting within 5 minutes, 2 Indian people from opposite lane (KL to Melaka) come and told us what happened. I told the situation and told I called the police, because at the first sight it seems to me that the guy may be fraud. The guy told me yeah we are from the phone call (but the guy actually very poor in English). Whatever my wife and me thought ok may be it possible the service dept. quickly send some service for help.
Today I was working in some SQLite3 tasks for one of our iPhone application. One of the problem I faced is that, I’ve to know the string data that contains a certain number of ‘ ‘ space. Suppose If I need to know the string data that has 2 space or may be 3 space then how can I do so.
The simplest thing I tried and that solved my problem by the following way:
if I one to search 1 space:
SELECT * FROM tbl_name where str_field LIKE '% %'
if I one to search 2 space:
SELECT * FROM tbl_name where str_field LIKE '% %% %'
if I one to search 3 space:
SELECT * FROM tbl_name where str_field LIKE '% %% %% %'
Some people ask me why I’m absent in Facebook app development tutorial writing? There are actually several reasons behind it. Firstly I retired active Facebook app developing for last 1 year. Then I involved myself for iPhone application development specially in last year along with freelance web development. And beginning of this year I’ve started my Masters study by research. So today I’m going to share my experience and thoughts in last 3 months of my study and research.
In late 2011, I wrote a blog post where I mentioned that I was trying to come in Malaysia for M.Sc study. I was trying and trying, applying here and there and finally in February 2012 I got the good news that, I’ve approved to get Research Fund in Multimedia University (MMU), Melaka Campus for study and research in Health Information Technology. My supervisor and co-supervisor are great and highly experienced people. My supervisor is by born American, completed his B.Sc & M.Sc in US, Ph.D in Germany and worked in various university. My co-supervisor is also Ph.D holder. So I will learn many things from them.
A few months ago I worked in a web project where we had to develop web & SMS application. Our main project is fully web application where we need to integrate SMS and some voice feature. We also wanted to integrate this feature easily and cost effectively. After some R&D in google search we found several web services for this purpose. Among all the services we liked Twilio.
There are several reasons to choose Twilio. One of the most important reason is, its very easy to integrate Twilio’s REST API. The price is also cheap compare to other services. In this post I’ll not write details about Twilio. You can easily learn more about it by there web site. I’ll mention some features that we integrated in our application.
Firstly I want to say sorry to my blog readers because I didn’t publish much article about facebook app development in 2011. Because I was very busy for my job, life and honestly said I was not an active facebook web developer in 2011. In computer science algorithm and data structure subject we learned “Time space trade off”. That means if you need faster solution you’ve to use more space and vice versa. This is happened in our life also. If you invest some time in a work you definitely have to leave some time in other works.
Whatever I’m writing this post to inform my friends and blog readers about my activity in 2011
I’ve an iOS application named Translator Free where I have been using Facebook iOS library to share translated text as user’s facebook status. Some day ago I noticed that facebook deprecated the message field. They deprecated it in July 12, 2011 and I noticed it much later. I’m surprised for their decision.
Most of the time people write code locally, upload them in remote server and test whether his facebook connect base application works or not. They either has a domain name or a dedicated IP address. Because when we create a facebook application we have to provide an URL in the setting page. In this tutorial I’ll show you how to develop and test facebook connect base application locally. This tutorial will only work for facebook connect base application or website, not for facebook Iframe base canvas or page application.
- We want to develop a facebook connect base website/application
- We want to test everything in our laptop or local pc not on the remote server
- Suppose we don’t have a dedicated IP address or any domain
