Galaxy Gift
by. Dolvin ≈ February 20, 2015
These days, I like to get a free gift from Galaxy Gift
As a Samsung user, we can get a free gift from Samsung every day using Galaxy Gift, it give us a voucher or a free foods / drinks from your favorite tenants.

But you have to tap fast when it show up, coz its limited and your connection have to good enough coz if not you'll be lose it

Galaxy Gift for Samsung Users

So, when my phone was vibrated, I tap it right away to get it as fast I could
sometimes I didn't see the place for redemption first, and I just saw it after I tap..
because of that, sometimes I didn't redempt it coz the redemption place was far or I didn't have time to do it

but it still fun! It's became a little bit addict for me.. hahaha..

Oracle Troublesome
by. Dolvin ≈ November 9, 2010
Oracle is cool.. and have a bigger size than SQL I think.. *correct me if I'm wrong*

but some feature is makes it complicated I think..
like LIMIT..
in SQL we can use limit to do pagination
but in Oracle we have to count it first and use rownum for know the data position.

Rownum Example :
in this example I show 5 data per page.. and this is to show page 2

SELECT *
FROM (SELECT ROWNUM AS rn, x.*
FROM (SELECT client_id, client_name
FROM tbl_client
ORDER BY client_id) x
WHERE ROWNUM <= 10)
WHERE rn BETWEEN ((2 - 1) * 5) + 1 AND (2) * 5


The others is autonumber..
in SQL we can use auto increment for it
but in Oracle.. we have to update from application or use trigger to count it

Example of create auto number in Oracle:

1. CREATE TABLE tbl (
2. tbl_id INTEGER PRIMARY KEY,
3. );
4.
5. CREATE SEQUENCE eq_seq;
6. CREATE TRIGGER eq_seq_trigger
7. BEFORE INSERT ON tbl FOR EACH ROW
8.
9. BEGIN
10. IF (:new.tbl_id IS NULL) THEN
11. SELECT eq_seq.nextval INTO :new.tbl_id
12. FROM DUAL;
13. END IF;
14. END;
15. /


so irritating..
humm.. why I miss this word? hihihih...

Hide and Seek Alarm Clock
by. Dolvin ≈ March 6, 2009
Do you have difficult to get up in the morning?
hohoho.. I think this gadget is suitable for u.. hmm.. especially for someone in my mind.. (and.. myself too..) hihii...
Run Away Alarm Clock
The alarm clock that runs away and hides to get you out of bed.
Clocky gives you one chance to get up. But if you snooze, Clocky will jump off your nightstand and wheel around your room looking for a place to hide, beeping all the while. You'll have to get out of bed to silence his alarm. Clocky is kind of like a misbehaving pet, only he will get up at the right time.
Price: 45.00

Features Include:
  • Set your alarm and as soon as it goes off the Clocky will lurch forward and then move off in random directions for 30 seconds (ensure you have set the snooze time to 0).
  • A snooze function on the alarm.
  • When the snooze expires the clock will launch off.
  • A retro cream colour.
  • Do not place Clocky on surfaces higher than 3 feet.
  • Not suitable for use on very thick carpet.
  • Suitable for ages 8 years+.
  • Requires 4 x AAA Batteries (not included).
  • Size: 13.5 x 9 x 9cm.

Mamoru Robot to Assist the Forgetful
by. Dolvin ≈ February 26, 2009
I found something interesting thing this morning.. hohoho...

This is an interesting conceptual robot created by the University of Tokyo, and is designed to assist the elderly in their daily tasks or for people who are suffering from dementia or simply forgetful.

Mamoru RobotMamoru-kun, an immobile and diminutive robot that could tell you where you last left those keys that you lose at an average of twice a day. Developed in cooperation with Fujitsu and Toyota, Mamoru-kun measures a mere 40cm tall and weighs 3.8kg. Mamoru-kun can find an object the owner is looking for within specified areas and alerts the owner about it either via verbally through speaker or by pointing at it using its jointed arm (it has another two joints at the neck). We're still very early on into the technology though - Mamoru-kun's lost-item-finding powers are limited to pre-programmed items in a specified area only.


For the system to work, you'd have to input items that often get misplaced for identification later. The whole area where you need Mamoru-kun to monitor would also have to be wired with cameras connected to the robot. While these requirements are severely limiting, Mamoru-kun's developers believe that it could provide great assistance "especially beneficial for elderly and sick persons. " Additionally, commercialization of the technology isn't expected until 2018, so there's a bit of time to improve it for practical use.
