Experimentation in SE (by Claes Wohlin et. al)

Four research methods in the field of of software engineering (SE), defined by Glass (1994) and Basili (1993):-
1. The scientific method - The world is observed and a model is built based on the simulation (e.g. a simulation model)
2. The engineering method - The current solutions are studied, and changes are proposed, and evaluated
3. The empirical method - A model is proposed and evaluated through empirical studies, eg. case studies or experiments
4. The analytical method - A formal theory is proposed and then compared with empirical observations.

Since SE is a cross-disciplinary subject, researches in SE were very much governed by human behavior when dealing with software development (Wohlin et.al). In this relation, the need to understand the underlying process when performing empirical studies is very important. Wohlin et. al (2000) outlines three major categories of empirical strategies:-

• Survey - normally performed in retrospect, when for instance a tool or technique has been used for a while
  
• Case Study - are used for monitoring projects, activities or assignments. Data is collected for specific purposes; is an observational study with lower level of controls
• Formal experiment - normally a controlled study done in a lab environment, thus provide high level of control. Subjects are either assigned to different treatment on random basis (true experimentation) or non-random (quasi-experiments)

Be careful if you go to Albert Park alone at 7pm onwards

This is just to remind all my frens (especially girls) and for those who reside in Auckland. Yati told me the story that one of our colleague (Korean guy) was attack by several guys when he was walking through the Albert Park at around 7pm sth. It was almost dark at that time and he was on the way back home. While he was walking, suddenly there was a man (with few others) grabbed his bag and punched his face (kesian, lebam muka dia..). He couldn't see the face of the man. Luckily the wallet and mobile phone was in the pocket, so there's not much valuable item inside the bag. But morale of the story is always be careful when you have to walk alone. Where possible, try to use the road or street that many other people used.

Akibat terlebih Vitamin "M"

Salam para pembaca blog yang budiman,
Inilah akibatnya terlebih Vitamin M..blog pun dah malas nak update...Nak cerita pun, cerita dah basi da... Tadi borak ngan Chea baru teringat meh la tengok sat..
Minggu ni sebenarnya sibuk melayan kenkawan yg dtg dr Msia, Titov dan Syazwan. Titov dtg sini ada hal keja sket, Syazwan pulak ada present paper kat conference ER2007. Both are my good friends. Titov now is doing PhD at IIUM and Syazwan baru abis last year. Syazwan was my batch mate mase undergraduate zaman dulu kala..Lama seh tak jumpa lepas 10 tahun baru terjumpa hahaa banyak nak cerita... OK lah itu citer pasal kenkawan saya.
Now, the reality is I've to settle my work for tomorrow's meeting. Again, will meet my wonderful supervisor at Downtown. This will be our last meeting before she go home to Brazil for raya plus holidays. Holidays??? yuhuuuu bestnya pegi holidays... Once a while, we need to take a break..we need to reward ourselves for our achievement (hopefully ada achievement! :-)) and one of the way is to leave aside the work and spend time for yourself to do anything you like during the break. Set the target to plan for holidays can also be a motivation factor. After working so hard, try to imagine and keep remind ourselves that once we get it done, we can take a break and go for holidays.. Remember that "Life is too short to worry about so many things!"

:-)

Back to work, to office, to the usual routine..

Korang raya sebulan ke?? Zaman tu dah berlalu...dah takde maknanye....hehe..So back to the reality of life! Back to research work, back to office, back to the usual stuffs we do everyday hopefully with the spirit of Syawal we can do our work with full energetic and enthusiasm insyaAllah..
Semoga kita semua mendapat keberkatan dariNya Yang Maha Esa..Ameen...

Have a blessed Eid to all...

Salam...I would like to wish "Selamat Hari Raya" to all my family and friends at all over the country- Malaysia, UK, Australia, US, Canda and New Zealand. I also wish to seek apologies (zahir & batin) from you for any of my misdeeds or wrongdoing.. May we able to celebrate the coming 'Eidul Fitri as a reward from Allah SWT for us after completing the fasting in the holy Ramadhan. InsyaAllah, may Allah SWT accept our effort and good deeds. May each and everyone us, had a wonderful and meaningful 'Eid..insyAllah..ameen..

Ihya Ramadhan

Ramadhan datang lagi..Selamat berpuasa kepada semua muslimin dan muslimat sekalian. Semoga puasa kita diberkati, insyaAllah semoga kita ikhlas mengerjakan ibadat ini semata-mata keranaNYA. Esok mula puasa di Malaysia, tapi kami di Auckland ni petang ni baru nak tengok anak bulan, jadi puasa mungkin start esok atau lusa (Jumaat). Rindu la pulak puasa mase kat M'sia. Rindu iftar dgn hosmet ku dulu, dila, zun..Skang ni diorang iftar dgn somi masing2 Alhamdulillah semoga gembira bahagia hendaknya...:) Rindunye solat tarawikh kat Tmn Perwira Indah, Tmn Setia, Tmn Melati.. Lepas bukak pose, bila azan Isyak kita kalut2 lari gi surau hahaa...Dila, ko ingat tak script nih "kamu benar2 kelewatan!" hahaaa hanya kau dan aku yang tahu. Maaf ye pembaca yg lain, ada kejadian yg sgt kelakar berlaku di sebalik script tu..ehehe..:)) Tahun ni pengalaman pertama aku berpuasa di perantauan, tapi aku bukan keseorangan di sini..Alhamdulillah, ada ramai lagi kawan2 lain di sini.
Ape pun, semoga kita semua berusaha melipatgandakan ibadat kita di bulan suci ini, mudah-mudahan mendapat pahala yg berkekalan insyaAllah.

One day at Auckland Zoo ;)

Oh I love animals..!! Cherish the moment seeing this lovely animals..!

lovely sea lion and its baby!
a mother giraffe waiting to deliver her baby!!! Tgh sarat sgt tu...kesian!
si lion king pemalas nih...kuat tidor...4 four them actually, and all sleeping!!!
And this one..cheeky huh??
there are more pics stored at my personal repository hehee... contact me for further details.
And here is the trio..from left: Kak Aida, Roger and me at the Japanese garden :)

Believe it or not? There's a garden inside the Zoo!! I was amazed... It's really awesome!! One thing I observed, the zoo here is really taking care the cleanliness of the surrounding place and they're doing best to preserve the environment to keep the animals feel at home as in their natural habitat. If you're animal lover + have free time = I recommend you to apply for voluntarily work in the zoo ;)

Let's love the animals!!

If you don't, learn to love the animals... they're so lovely!!
