Atacama's Cloudy Night

Storm clouds do sometimes come to Chile's Atacama desert, known as the driest place on Earth. These washed through the night sky just last month during the winter season, captured in this panoramic view. Drifting between are cosmic clouds more welcome by the region's astronomical residents though, including dark dust clouds in silhouette against the crowded starfields and nebulae of the central Milky Way. Below and right of center lies the Large Magellanic Cloud, appropriately named for its appearance in starry southern skies. City lights about 200 kilometers distant still glow along the horizon at the right, while bright star Canopus shines above them in the cloudy sky.

Sunset on Deck 10

We had another lovely sunset off the deck here on the cruise through Alaska. Just inside that glassed room to the left is where I spend a lot of my days, drinking coffee and editing photos... or getting ready to go out and take more photos!  

This one was handheld with the NEX-7 and 10-18mm lens... I was worried about the low-light handheld stuff, but everything aligned easily enough!

If you've been through the HDR Tutorial at http://www.StuckInCustoms.com/hdr-tutorial/ -- you'll see I often don't suggest letting Photomatix auto-align your handheld shots... but I think I may be reversing my theory on that.  I think something has changed in that algorithm, and it's getting very very good.  Anyway, I may have to update that bit of the tutorial soon after more testing...

What?!!
 
Wow...

" In their research paper titled RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis, Daniel Genkin, Adi Shamir and Eran Tromer et al. present a method for extracting decryption keys from the GnuPG security suite using an interesting side-channel attack. By analysing the acoustic sound made by the CPU they were able to extract a 4096-bit RSA key in about an hour (PDF). A modern mobile phone placed next to the computer is sufficient to carry out the attack, but up to four meters have been successfully tested using specially designed microphones."

This place has something of an nostalgia associated with it. They don't accept cards, the place is not very large. Having said that, I find myself going back again and again simply for the food. The manager knows me now and greets me every time I walk in. Also the desserts are to die for! Tip: try the Churchill favorite salad and cheddar baked chicken.

Excellent and authentic bengali food. As a Bengali myself who is out of Kolkata, this joint amongst others has helped me survive through crippling home sickness. Try the bhetki mach er paturi and chingri malai curry.
