Facebook is the virtual home to more than 800 million active users, so any change to how the network operates is a big deal. And nothing could be bigger for the social hotspot than completely revamping everyone's front-facing profile page, and that is exactly what is happening today. Starting this morning, the new Timeline feature — that up until now has been an optional switch — is now mandatory.

The Timeline differs from the default profile pages we know and love in several ways. Now, rather than showcasing only your most recent posts, your personal front page can be scrolled back months or years at a time. Most importantly, this change can offer visitors a glimpse at your entire social networking past, all the way back to the day that you joined up. The revamp can be both a blessing and a curse for seasoned social networkers, as it can produce a bit of pleasant nostalgia, but also drag up some of your less proud public moments.

Left untouched, your Timeline may remind of you of breakups, job troubles, or even a few unfortunate party photos that you have long since buried. Depending on your settings, these black marks on your digital past could allow new followers — including friends or business associates — to see a side of you that was better kept tucked away.

Privacy is already a hot topic for Facebook users and the network's litany of sharing options can be difficult to navigate, even for the most experienced users. The company isn't oblivious to how the Timeline may drag up some unwanted past events, so a short buffer zone is in place to allow you to modify your online persona before making its new debut. You now have until Tuesday, January 31 to erase any past Facebook scars you'd prefer to hide.

The mandatory Timeline rollout will undoubtedly catch some by surprise, but you don't have to fall victim to the ghosts of past updates. Take some time to review your social networking history and don't hesitate to prune anything that you wouldn't want on the front page of a local newspaper, because as of right now, the clock is ticking. Or, of course, you could always jump ship to Google+ instead. # By Mike Wehner, Tecca

As you already knew, there are only five default languages for SIRI on iPhone4S. It has the Australian English, British/UK English, and English in the United States, French, and German. But wait, Singapore’s version of Siri is now available! Surprised? Well, you better listen on Mr Brown’s version of Siri.  Meet SIMI, Singapore’s funny and witty assistance on iPhone4S! 

Like anybody else out there who have been waiting for the most-awaited release of iPhone4S, I had finally gotten mine after Apple Singapore released it last October 30.  I was so excited to take it out from its beautiful hard box after queuing for more than an hour at a local licensed store.

What is so special about the iPhone4S?  The amazing Siri, Apple’s new voice recognition technology, has been the topic of much conversation over the last month.  I too am left speechless when asking questions that at first blush seem ridiculous.  Responses to questions such as “Siri, what do you look like?”  or “Siri, I love you so much!” will elicit laughter and jaw dropping looks only magicians are used to seeing.

All fun and games aside, what Apple just released represents a fundamental shift on how we will interact with computers – and to an extent the rest of the world. Asking her to send messages from your list of contacts, calling someone, checking emails, setting-up reminders and appointments, asking her to answer the conversion of units, current time, weather conditions from a specific location, and even searching a particular information from the web are the awesome and fantastic features of Siri.

As impressive as Siri can be, we still hear naysayers balking at the current ineffectiveness of the technology.  They say it’s not perfect, it can’t yet complete complex tasks such as interacting with the Apps on your device, and when in doubt it defaults to a web search for your request. Siri couldn’t even find and locate hotels and restaurants here in Singapore. That is because its GPS has been designed to work in the US, UK, AU, Germany and France and soon in Singapore, I guess.  Although I am fascinated with Siri I must agree we have only scratched the surface and more work is ahead.

Nevertheless, I still love the iPhone4S because it has a dual-core A5 chip. All-new camera and optics. iOS 5 and iCloud. It’s the most amazing iPhone yet.
