Bloom energy: The next generation power?

Recently, a Silicon Valley startup has come into the news. Bloom energy has started manufacturing new age fuel cells that are claimed to be small, reliable and clean. These small cells can be used as mini power-plants anywhere from a basement to power a house to datacenters and large establishments.

The research which was secretive for a long while was unveiled last week, led by KR Sreedhar. He happens to be an alumni of NIT, Trichy: a proud moment for all us Nittians! (His profile says Madras University but it happens so that REC, Trichy back then was not autonomous, but was affiliated to Madras University).

Catch the following video to get a first hand update on whats new about Bloom energy fuel cells.

BitTorrent Visualization

This is a good Javascript visualization of p2p file exchange using BitTorrent.

You can add seeds, peers and see how the bitfield on each peer changes with time.
This is helpful to understand how it works.

Upgrading Apple memory

Everyone wants computers to be faster than what they are! For an average user, the default memory option is more than sufficient. After about a year after buying my Macbook, I realized that Firefox memory usage, being able to run VMs and keep a lot of applications open surely needed more memory. Its hard to find out if you really need more, but I had been frequently monitoring Activity Monitor to know that I was almost never CPU-bound.

So once I was partially convinced of buying new RAM, I went over to Apple Store and saw that 4GB of compatible RAM costs $200! That was a bit too much for just RAM. A little browsing around told me that Apple made customers think that Macbooks are too picky with RAM, and may not work with all memory or brands.

More browsing with sellers like MacConnection and MacMall gave me utter confusions about memory specs and compatibility. I wish I had come across MacRumours guide to buying new RAM earlier. So I followed their advice and downloaded the Crucial Memory scanner to identify my system model and the right memory. I had the 2.4GHz 13" late 2008 aluminum unibody model (MB467LL/A) and crucial found me the right RAM with some model number (CT898327).

Using more Google in parallel, I arrived at another popular Crucial model number (CT2KIT25664BC1067) which had worked for people before. And with the final search with both these model numbers, I landed on a forum where I learned that someone had inquired with Crucial itself, and these model numbers were indeed the same (marketing tactics!).

Finally, the Amazon search led me to this, and I was able to buy it for $20 cheaper than Crucial's website, and $100 cheaper than Apple's website! Happy as I was, the next challenge was to get the RAM fitted properly into my mac. Again, Mac rumors pointed me to OWC's website which has awesome installation videos.

If you have the right type of screw drivers and follow the instructions, it indeed takes less than 10 minutes to get the job done and boot up into 4Gigs. Well, its a positive experience and I've not had any issues for 2 days :) Now, I can run Windows 7 and see how good it is really. And seriously, Microsoft has done a good job in making it look good and yet feel as light as XP. It has been a year since I left Windows completely and I have not had any issues that make me want to use Windows - I am a happy Apple customer.

Specs: 4GB Kit (2GBx2), 204-pin, PC3-8500, SODIMM, DDR3, Non-ECC, Unbuffered. Amazon, Crucial, Apple store.

Hibernation

I realized a couple of days back (and many more times earlier) that this blog has been hibernating. All this while, I just did not bring myself to sit and pen something down. This one is to catch up on those missed months.

I have been keeping myself busy primarily with my PhD coursework in my 4th semester at Purdue. This is the time when I finish most of my coursework and delve into research. I'll be taking my final oral Qualifier exams this semester and I hope it goes well and I officially become a PhD candidate. We worked on a couple of paper submissions and the reviews are pending on them.

Last Thanksgiving tempted me a lot into buying my first DSLR camera - a Canon 500D (Rebel T1i). I can see people going - "Aah, one more guy with a fancy camera", but I really hope I can impress myself with my photos. I truly believe that photos keep memories alive through the years. Anyway, I've decided to start with the kit lens 18-55mm and a 55-250mm telephoto zoom lens. I've transformed into a Flickr user over Picasa after receiving recommendations from a couple of friends and here is my Photostream. The zoom lens is producing some superb images when I use it for shooting portraits with easy background blur.

My camera is my second best companion while traveling. I prefer spending and visiting different places instead of lazing back at home. Last winter, I went on a small road trip with Ashwathi to Brown County state park. I was pessimistic at first about the worth of this trip during winter, but it turned out to be quite a nice trip. Brown county park is located near the small town of Nashville - I really mean small; the whole town is built around Van Buren street. The park was a quiet escape and the weather was in the 40s and partially cloudy with bright skies, perfect for photography. I'd love to head out to a similar park sometime in Fall to camp and spend more time close to nature. And finally, I spent a quiet and exciting New Year back home at W Lafayette with an Italian Dinner at Olive Garden.

I've also been doing this one-new-restaurant-every-Friday thing, which actually started out last Fall. A couple of us guys pick some new cuisine and restaurant every Friday and try it out. Although we've had a few experiences that were not too good, we get to try out so many different styles of cooking. And after all, its TGIF!

Meanwhile, I also caught up on movies such as Sherlock Holmes, 3 Idiots (Hindi) and Avatar (3D IMAX) and a couple of other older movies. I am so happy we discovered the Purdue DC++ network for content. We had a similar one in our GZ LAN at NITT and this brings memories back..
