Digital Living Network Alliance (DLNA) is a cross-industry standard supported by leading consumer electronics, computing industry, and mobile device manufacturers that supposedly will enable a seamless environment for consumers to share and grow new digital media content within a network area.
Works somehow like bluetooth does except that it has more area range, DLNA is a new standard covering both wired and wireless environment that will allow distribution of media content through the 2 networks environment. Since it is supported by many leading electronics goods manufacturers, it is expected to be the new crave of the technology that will give value to the consumers.
Just imagine, we buy a camera and take photos with it. Supposedly the camera adopted the DLNA standard, it will be very convenient to move photos around to another DLNA-based device such as TV or PSP just to view the image on a click effort. Examples of DLNA-based device that can be seen on the market is on mobile devices category, take for example Sony Ericsson W715.
So, in summary, I could say that DLNA will enable consumers to easily acquire, store, access, and share digital content within DLNA-based device interconnection. Who knows whats the limit and hopefully plenty of features still to come.

Types of Domain
When you first subscribe to a web hosting service, most of the hosting service provider will give you privileges to create 'extra' domain in addition to your registered domain name. The term extra is vague. It refers to 3 types of domain available for implementation. The types of domain are:
1) Sub domain
A type of domain that belongs to the original domain. Configuration can be made to the web folder that will allow visitors to visit a website by creating a new folder called either 'www.domain.com/subdomain' or 'subdomain.domain.com'. Setting up sub domain is free and you can add as many as you want (memory allocation is the limit). It was generally use to separate different functions of your website. One maybe used to login, and another for chatting. Ever see mail.google.com or mail.yahoo.com. This is the type of sub domain.
2) Addon Domain
A domain that is much like the sub domain was but the only difference is it is treated independently of each other. It can be created within your web folder and visitor will look at it as it was a usual domain that does not related to your website. For example, instead of 'subdomain.domain.com', you can publish a new domain called 'subdomain.com'. See the difference. It was completely unrelated to the original domain. Usually, web hosting provider will charge an additional fee for each new Addon domain added.
3) Parked Domain
A type of domain that redirects visitors to a predefined domain. For example, if you type 'www.somename.com' on the address bar and press enter, you will be redirected to the predefined domain such as 'www.afterredirect.com' instead of the typed domain url. Webmaster loves to do this if they have multiple domain that conveys the same information and sometimes it can be used by spammers to redirect a visitor to a forged website. So be careful. Park domain is free to implement (depends on web hosting provider).

A lappy niche
Planned to buy a laptop but unsure of which and what are the best for you? You come to the right place. I recommend for those who want to buy a new laptop, buy a new one or if you buy 2nd hand one, make sure it is still covered by warranty or the owner is your close friend, not a meet once friend.
So, here are the tips on buying a laptop. I would like to credit the shop assistant of All IT hypermarket, my tech-savvy friend kaizeru, and of course the triple www for giving me the tips:
1) Processor
Based on current trend, duo core is common. But please take note that out there there are dual core processor and core 2 duo processor. Technically, core 2 duo means there are 2 processor inside while the dual core means 1 processor that was divided into 2 parts. In this situation, it is recommended that you choose core 2 duo because it is faster than dual core.
2) Memory / RAM
Easy to say, the highest the better. If you are a kind of user that lives in the world of IT (like me a computer science student), 4GB RAM is enough. It depends on the type of Operating system you use too. I fyou use windows XP, 1GB RAM is sufficient, if you use Vista, At least 2GB RAM is recommended. The usual type of RAM is DDR SDRAM. Look at the DDR number though, as if it was DDRII, it is twice much faster than DDR. DDRIII is of course much faster. Depending on the processor, DDRII is more suitable to be used with core 2 duo since it can utilizes up to 75% of the bus speed, which is typically 667MHz (bus speed is the transfer speed of data between processor, memory (RAM), and Hard disk drive ; the highest the bus speed, the better).
3) Wi-fi
There are 4 standard in place currently for wifi which are 802.11 a/b/g/n. Each standard delivers different speed (refer here for more description), but the common are 802.11g and the latest is 802.11n. Technically speaking, 802.11n has a data rate of more than 100Mbps, double of 802.11g data rate.
4) Bluetooth
Bluetooth technology are common in laptops but it is unnecessary because it consumes laptop battery. If we intend to have bluetooth, just buy a bluetooth adapter (cost not more than RM30). Bluetooth can be used to setup a private area networks (PANs) on which involved user can transfer files up to 1Mbps between each other in a 10m range. Indeed limited, there are research going on to enhance the speed and range of bluetooth that will boast the speed equivalent to that of Wi-fi by the bluetotoh special interest group (SIG). The research propose that bluetooth use the wifi channel to transmit data on 'use as needed' basis.
5) Battery
Battery lifespan is the most important thing to consider when buying a new laptop. Typically, a laptop can reach a 3 hour mark base on norm usage. If we use it at home, plugged the power adapter and remove the battery from its compartment. Fail or forgot to do so, the battery may drain. Also, only charge when the battery is about to drain, don't charge if it still has more than quarter of power. Before buying a laptop, look at the battery power specification, there is a number like 4800mAh. The highesr the number, the longer the battery can last.
