Is Facebook Going to Start Forcing Us to Make Some Info Public?

To say that Facebook has come under fire for its privacy (or lack there of) would be an understatement. They’ve been opening up users’ data to the world with changes to privacy settings after the introduction of several new features. All of that seemed to come to a point for me today when I logged in to my profile and was greeted with a new feature to find pages I might be interested in linking to. Handy? Well, maybe. The feature scans your profile for key elements and finds pages “for you” so you can join. Problem is, it does things like search hometowns, jobs, etc. which is all the information in our profiles that we’re trying to keep private in the first place. Keep in mind that pages are public to the world, and for me personally, I’ve become very selective in the pages that I link to. But what was scary were the options at the bottom of the prompt:

If you’ll notice, there’s a very important option that’s missing: “No”. Perhaps this is a misconception due to a poorly-worded prompt, but it was a bad one to screw up at this stage in the privacy game.

Hands on with Opendedup

After reading about Opendedup on Slashdot this weekend, I decided to try it out to see how well it all really worked. My test server was an install of Ubuntu 9.10 x64. If you happen to be using that stack, the installation isn’t too difficult:

Download required files (adding links to the most recent versions of each, check for newer versions as necessary):
cd /usr/local/src
wget http://download.java.net/jdk7/binaries/
wget http://opendedup.googlecode.com/files/debian-fuse.tar.gz
wget http://opendedup.googlecode.com/files/sdfs-latest.tar.gz

And install:
chmod +x jdk-7-ea-bin-b87-linux-x64-25_mar_2010.bin
./jdk-7-ea-bin-b87-linux-x64-25_mar_2010.bin
(follow instructions – afterwards, but sure to set the JAVA_HOME variable)
export JAVA_HOME=/usr/local/src/jdk1.7.0
tar zxf debian-fuse.tar.gz
cd debian-fuse
dpkg --install *.deb

Next, just extract the SDFS packages and use:
tar zxf sdfs-latest.tar.gz
cd sdfs-bin

Now, we make our filesystem and mount it:
./mkfs.sdfs --volume-name=deduped --volume-capacity=5000MB
./mount.sdfs -m /srv -v deduped

Assuming all goes well, you should have a newly mounted deduped mount.

Great results from testing in the small
As a test, I copied over a sample song from my music collection (what nerd doesn’t enjoy a little Weird Al?). Copying to /root, the file size was 2.9MB. Once I copied it to my deduped /srv directory, the file size took just 46K on disk! Not too shabby. Just as a sanity check, I copied the file back off the deduped filesystem and the file size grew back to normal.

Things not all rosy in Opendedup-land
I decided to try throwing a little more data at it as a test and copied over the Documents directory from my desktop. The folder that I copied was slightly over 600MB of docs, text files, images, and a few other file types. During the file copy, Opendedup took a significant amount of memory (it hung around the 90% mark). My test machine was a small virtual machine (1 CPU, 2GB of RAM) and the file transfer slowed it down significantly. Eventually, I got curious as to how much had been transferred. I cd’d to the test dir and did an ‘ls’ which never completed and I could no longer open a new shell via SSH to the vm either. I’m sure this would be much better if I had the resources to throw a little more RAM and CPU at it (since I’m running the minimum), but I don’t have time the resources to try at the moment.

Conclusion
Overall, the technology seems really promising and pretty straightforward to use. If my compression rates hold true, this could dramatically cut down on the amount of disk space needed to store my backups and virtual machine templates. Judging by the performance I’ve seen thus far, I don’t think I’d want to run this in production, but it looks promising, nonetheless.

Who’s Laughing Now? Windows Mobile to Copy iPhone?

Ballmer’s famous reaction to the iPhone seems all the more funnier now, looking back. According to claims, Microsoft is planning some changes for Windows Mobile 7:

  1. No multitasking
  2. Use a push notification for updates
  3. Use the iPod Touch ZuneHD interface
  4. Force apps to be installed via the iTunes App Store Windows Marketplace

While these changes aren’t confirmed yet, even if one or two of those changes are true, they scream jealousy. Why these changes? Microsoft needs to be able to compete with Apple on speed, battery life, and stability. While I am certainly not in any inner-circles close to this, I’m sure Microsoft is finding that people want stability, responsiveness, and good battery life in their cell phones. I know that responsiveness and stability are top on my list (I haven’t been overly happy with a phone with the exception of my BlackBerry ((no AT&T coverage in my area))  for some time now over those very things).

Whether Microsoft wants it or not, the world is slowly drifting away from do-it-all devices that have to be setup by power users. The world wants phones that they can turn on, install apps, and start using without having to worry about one application slowing down the phone or having too many open causing the phone to crash.

But not to worry, to those now doubting Microsoft, they thought of all of these radical changes all on their own..

Gmail to Add Twitter-Like Clutter

While I can’t say that I’m surprised, I’m a bit frustrated and disappointed in Google over the recent news that they are adding a Twitter-like clutter status to the Gmail interface. While I appreciate fancy new tools built into apps I already use as much as the next geek, I really, really don’t need yet another social networking tool to update, integrate, and look at. Seriously, it’s not new content. Does anyone really put unique content on Facebook, Twitter, Linkedin, and every other social networking site they belong to? I certainly don’t and don’t know anyone who does. My accounts are all inter-twined and I’m tired of having to filter out the duplicate data on those sites. Adding yet another list of the same things from my friends is just clutter in a used-to-be clean interface.

UPDATE:

According to a Slashdot article today, the problem looks like it may be much worse. According to the article, Gmail will be adding Facebook-like photo albums and comment feeds. Fortunately, the Gmail social networking tools are opt-in, so perhaps I won’t have to see the clutter when I don’t want to? We’ll see.

Soon We Will See Just How Loyal Search Users Are

With today’s announcement that Canonical is changing the default search provider to Yahoo, Apple’s rumored talks with Microsoft, and cell phone providers such as Verizon also jumping to Bing, we may get to see just how big of a role the default settings have on people’s search preferences. Google has been dominating the search market pretty much since the beginning with a significant boost coming from the fact that Google is the default in several of the world’s browsers, though some of it is some good old-fashioned branding and marketing.

Canonical’s decision to change the Ubuntu default search engine and rumors that Apple may be soon to switch the default provider on the iPhone (I’m assuming with regular old Safari soon to follow), Google will no longer be the default on most of the major desktop OS’s of our time. Verizon has also struck a deal with Bing and made it the default search provider on its mobile phones. I personally was pretty mad the day that the Bing icon on my BlackBerry, but that’s a story for another day.

Citing concerns over privacy, there have been several who have spoken out against Google as well. Google has even stated that it is considering pulling out of the huge market of China.

Despite these things, Google’s search market share has continued to increase month after month. These next few months will be interesting to see what happens to market share as these talks fall into place. The true test of the Google brand will be for those users who have to go out of their way to choose Google as their search provider, rather than Google enjoying its nice defaults that it has enjoyed over the past few years.
