Google Plus vs Facebook

- Extract from New York Times -

Google has tried several times, without much success, to take on Facebook and master social networking. Now it is making its biggest effort yet.

On Tuesday, Google introduced a social networking service called the Google+ project — which happens to look a lot like Facebook. The service, which is initially available to a select group of Google users who will soon be able to invite others, will let people share and discuss status updates, photos and links, much as they do on Facebook.

But the Google+ project will be different in one significant way, which Google hopes will be enough to convince people to use yet another social network.

It is meant for sharing with groups — like colleagues, roommates or hiking friends — not with all of one’s friends or the entire Web. It also offers group text messaging and video chat.

“In real life, we have walls and windows and I can speak to you knowing who’s in the room, but in the online world, you get to a ‘Share’ box and you share with the whole world,” said Bradley Horowitz, a vice president for product management at Google, who is leading the company’s social efforts with Vic Gundotra, a senior vice president for engineering. “We have a different model.”

When it comes to social networking, Google finds itself in an unusual position, one that its competitors in Web search know all too well: playing catch-up with a service that dominates the market.

The debut of Google+ will test whether Google can overcome its past stumbles in this area and deal with one of the most pressing challenges facing the company. At stake is Google’s status as the most popular entry point to the Web. When people post on Facebook, which is mostly off-limits to search engines, Google loses valuable information that could benefit its Web search, advertising and other products.

But Google+ may already be too late. In May, 180 million people visited Google sites, including YouTube, compared with 157.2 million on Facebook, according to comScore. But Facebook users looked at 103 billion pages and spent an average of 375 minutes on the site, while Google users viewed 46.3 billion pages and spent 231 minutes.

Advertisers pay close attention to those numbers — and to the fact that people increasingly turn to Facebook and other social sites like Twitter to ask questions they used to ask Google, like a recommendation for a restaurant or doctor.

Analysts say that Facebook users are unlikely to duplicate their network of friends on Google+ and post to both sites, but that they could use them for different types of communication. Google+ could also attract Facebook holdouts who have been uncomfortable sharing too publicly.

“Can someone eclipse Facebook in terms of its hold? It is a fantastic broadcast mechanism,” said Charlene Li, a social media analyst and founder of Altimeter Group, a technology research firm. “But if Google becomes the owner of your private groups, it’s going to be a splintering of our social lives.”

Mr. Gundotra and Mr. Horowitz said that knowing more about individual Google users would improve all Google products, including ads, search, YouTube and maps, because Google will learn what people like and eventually personalize those products.

“To think we could achieve Google’s stated mission of organizing the world’s information absent people would be ludicrous,” Mr. Horowitz said.

But Google has been criticized for failing to understand the importance of social information on the Web until competitors like Facebook and Twitter had already leapt ahead.

Larry Page, Google’s co-founder, regrets Google’s failure to lead in this market and has spent time working with the team since he became chief executive in April, people at the company say. He promoted Mr. Gundotra to senior vice president this year, placing him on an equal level with the heads of Google’s core products like search and ads.

Part of the blame, analysts say, falls on Google’s engineering-heavy culture, which values quantitative data and algorithms over more abstract pursuits like socializing.

Legal to JailBreak your IPhone

It is now legal to jailbreak your Iphone in US. In the new exemption of the Digital Millennium Copyright Act (DMCA) that was updated yesterday, users can now legally break through copyright protection on their mobile phones in order to "execute software applications, where circumvention is accomplished for the sole purpose of enabling interoperability of such applications."

Users are also now able to unlock firmware that ties a mobile phone to a particular wireless network.

Advanced Format from Western Digital

Western Digital recently launch the first Advanced Format drives. It is develop as an education campaign about the technology. So what actually is the Advanced Format? It is actually the drives that uses 4KB sectors instead of the traditional 512 byte hard drive sector.

Hard drive uses Error Correcting Code (ECC) to find and correct any errors that occur. For a drive maker to add more space, they ultimately need to improve their error-correction capabilities, which means the necessary ECC data requires more space.



The problem is on ECC correction in 512B chunks, ECC can be more efficient when using a larger chunks of data. Even though larger sector rquires more ECC data than for a single 512B sector. But the overall ECC required on a larger sector is less than the sum of multiple sectors in order to maintain the same level of operational reliability. One estimate for 4K sector technology puts this at 100 bytes of ECC data needed for a 4K sector, while 320 (40x8) bytes for 8 X 512B sectors.



But this new format had a downside. There is a risk that a partition could be misaligned compared to the 4K physical sectors - where it would be unwittingly started in the middle of such a sector. As a result, the clusters of a file system on that partition would end up straddling 4K sectors, which would cause performance problems.

Kingston SSD 64GB SSDNow V+

Nowadays, we see alot of SSD (Solid State Drive) in the market. And here comes the new SSDNow V+ series from Kingston, not to be confused with the original V series. The original V series is part of Kingston's new value series lineup targeted at the mainstream DIY and upgrade market with a decently fast drive at affordable prices. Its read/write speeds are advertised at 100MB/s and 80MB/s respectively and comes in 64GB and 128GB capacity.

The newer V+ series that is mention here have better specifications such as 220MB/s sequential read speeds and up to 140MB/s write speeds for the 64GB edition. It also comes in capacities up to 256GB and has lower idle power draw than the original V series. Both are basically MLC-flash equipped drives but the V series uses the jointly developed controllers from JMicron and Toshiba, whereas the V+ series uses a Samsung controller. Another highlight point for the V+ series is its huge 128MB cache memory that should definitely distinguish it from the normal V series that has none.

Seagate first solid state drive


Pulsar, is Seagate first solid state drive (SSD). It is designed for enterprise blade and general server applications. It uses single-level cell (SLC) technology, delivers up to 200GB capacity, and is built in a 2.5-inch small form factor with a SATA interface.

It achieves a peak performance of up to 30,000 read IOPS and 25,000 write IOPS, 240MB/s sequential read and 200 MB/s sequential write. Its SLC-based design optimizes reliability and endurance and helps provide a .44% AFR rating with a 5-year limited warranty.

“The enterprise SSD market is now primed and well-positioned for growth from both a revenue and unit perspective, with Gartner estimating unit growth to double and sales to reach $1 billion for calendar year 2010,” said Joseph Unsworth, research director at Gartner.“Superior enterprise SSDs provide transformational capabilities when optimized in storage and server environments.”

Re-invent the plug


"The MacBook Air is the world's thinnest laptop ever. However, here in the UK, we still use the world's biggest three-pin plug," says Min-Kyu Choi, a Royal College of Art's graduate, who design a plug that folds down to the width of an Apple MacBook Air.

The plug is just 10mm wide when it is folded. To unfold it, the two live pins swivel 90 degrees, and the plastic surround folds back around the pins so the face of the plug looks the same as a standard UK plug. Choi also created a multi-plug adaptor, a compact standard plug sized unit with space for three folded plugs to slot in, as well as one that charges USB devices.

Choi picked an everyday product that most other designers find too mundane to dabble with and drastically improved it. This should make other designer start thinking again.
