I notice that there is a new species of flat panel television called LED TV available in the electrical shops nowadays. Here are some of the fact finding.
Pioneered by Samsung, LED TV is in fact a LCD TV using Light-Emitting Diodes (LED) as its backlight, contrasting to the Cold-Cathode Fluorescent Lamps (CCFL) backlight of normal LCD TV. This innovation has made Samsung to receive a prestigious award from European Image and Sound Association (EISA) in 2006, for its premium display technology in terms of true colour representation with a 46% larger colour gamut and the industry's highest contrast ratio of 10,000:1 by then.
According to Samsung, their LED TV provides improvements in 3 distinct areas:
1. Breakthrough picture quality with higher contrast, sharper motion and enriched colour.
2. Ultra slim design at only 1.2" deep with lighter weight.
3. Environmental friendly with 40% electric power savings than normal LCD TVs, produce less heat, and also lead and mercury free.
It is also claimed that the LED light source can double the TV panel life compared to the CCFL panels.
Beside Samsung, other manufacturers such as Sharp, Sony, LG, Panasonic, etc. have also produced their own series of LED TV. Of course, you will expect the price of LED TV to be higher than LCD TV of the same size.
Meanwhile, the television technology keeps on progressing, and the next generation will be a true LED TV called Organic LED TV (OLED) using the Active-Matrix Organic Light-Emitting Diodes (AMOLED) technology, this time to be led by Sony.
The primary benefit of OLED displays over the LCDs is that OLEDs do not require a backlight to function, and consume even less power. This technology also enable the panel to be ultra-slim, weight even lighter, and more robust. Of course, better quality display can also be expected.
On the other hand, we can notice that the plasma TV gradually step down from the TV technology warfare, following the CRT TV, as there is not much technology breakthrough and also less R&D investment allocated by the major manufacturers.

Database synchronization/replication with SymmetricDS
SymmetricDS is an open source, feature rich, web-enabled, database independent, data synchronization/replication software. It is written in Java 5 and released under GNU Lesser General Public License (LGPL) version 3.
It uses web and database technologies to replicate tables between relational databases in near real time. The software was designed to scale for a large number of databases, work across low-bandwidth connections, and withstand periods of network outage. By using database triggers, SymmetricDS guarantees that data changes are captured and atomicity is preserved.
-
MySQL version 5.0.2 and above
Oracle version 8.1.7 and above
-
PostgreSQL version 8.2.5 and above
-
Sql Server 2005
-
HSQLDB 1.8
-
H2 1.1
-
Apache Derby 10.3.2.1 and above
-
IBM DB2 9.5
-
Firebird 2.0 and above
SymmetricDS allows for 2-tier and even n-tier synchronization, which can be configured to push data (trickle-back) or pull data (trickle-poll) at an interval, as illustrated below:
The software is installed either standalone, as a web application in a Java application server or can be embedded into another Java application.
SymmetricDS will be useful for data synchronization between a central database and multiple remote databases. This kind of requirement is often in:
- HQ and branches
- General office and retail outlets
- Police HQ and stations
- Ministry of education and schools
- Ministry of health and hospitals & clinics
- etc.
