Someone asked me how Twitter made money. I said it wasn’t making any. At that time Twitter wasn’t making any profit at all. Promoted tweets will change all of that. Twitter plans to roll out the much anticipated “promoted tweets” in the next two weeks. It makes sense for Twitter to finally earn some well-deserved profit. The question that is in everyone’s mind is, how annoying will these promoted tweets be. I don’t mind an ocassional ad or two as long as it is keep in check.

If you are in the market for a 2011 MacBook Air, you better check the SSD (solid state devices) that comes with the laptop. Apple ships both Samsung and Toshiba SSDs. Why is Apple using two suppliers? It’s probably due to shortage of SSDs. What’s the difference between Samsung and Toshiba SSD? The difference is in speed, not by a whole lot, but it’s something to consider when making a big purchase. You want the best bang for your buck. Here the details about the speed difference from Engadget:
The 128GB Samsung SSD in his 11-inch Air was able to achieve 246 MB/s write and 264 MB/s read speeds. When he switched to the 13-inch model, however, speeds dropped to 156 MB/s and 208 MB/s, respectively, using that notebook’s 128GB Toshiba SSD.
We compared speeds on two generations of 13-inch models, and confirmed Jonathan’s findings.
During our tests, the 256GB Samsung drive in our older model achieved 214 MB/s write and 251 MB/s read speeds, while the 128GB Toshiba drive in the new MacBook Air scored 184 MB/s and 203 MB/s during write and read tests, respectively.
Samsung SSD is definitely the way to go. How can you tell if you have the Samsung or Toshiba SSD? From ZDNet:
You can check which SSD module you have by going to About this Mac > More info… > System Report… (the new name for System Profiler) and clicking on Hardware > Serial-ATA in the left pane. If the enter for APPLE SSD is followed by SM, you have the Samsung, if it’s followed by TS you have the Toshiba module.
It might be preferable to buy a 2011 MacBook Air directly from an Apple Store, rather than buying it online. At the very least, you can check the SSD before making a purchase.
You can now watch movies at Walmart.com on the very same day when the DVD comes out. Wal-Mart bought Vudu.com eighteen months ago and is now poised to serve over 20,000 movie titles online. ABC.com breaks down the price structure like this:
Movies are available at Walmart.com to rent for $1 to $5.99 or to purchase for $4.99 and up. Wal-Mart is not offering subscriptions, making its service more similar to Apple Inc.’s iTunes, which charges $3.99 to rent newly released movies and $14.99 to buy a movie.
In addition to Netflix, another competitor streaming movies and TV shows by subscription is Hulu.com, which now offers a premium service for $7.99 a month with more back-season shows and more movies. Without a subscription, Hulu viewers can watch shows and movies free in exchange for watching advertising.
The online streaming companies, Apple, Netflix and Hulu, now have legitimate competition from Wal-Mart. And it’s cheaper.
I’ve signed up for Google Plus invite several weeks ago, but still no invitations from Google or anybody. It’s similar to my experience when Gmail first appeared many years ago. I didn’t get one until a few months later. So, if you have extra Google Plus invite, please send them my way. Please send the invite to:
