Comment: No mention of crop factor WTF? (Score 4, Interesting) 192

by lhaeh (#48853719) Attached to: Samsung's Advanced Chips Give Its Cameras a Big Boost

Notice how the 5dMKII pics are zoomed out? That is because it is a full size sensor. Due to sensor crop, the image produced by the other two cameras gets zoomed in by a factor of 1.6 or so. Naturally, you can see more detail if it is zoomed in. Also, the reviewer is talking about having issues with camera shake while on a tripod, has he not ever heard of a remote shutter release?

It is interesting to wonder how much process size vs. pixel density effects sensor noise, and Samsung certainly has some nice fab facilities.

Still this reviewer seems like an idiot or a paid shill. I’ll wait for something from DPReview.

So, Bitcoin wil be subject to volatility, like every other currency and precious metal in history, and that will cause troubles for the people who actually extract the stuff. Who (aside from anyone in the mining business) knew?

The problem with bitcoin is its volatility relative to other currencies. Combine purely speculative/thinly traded exchanges with a lack of an underlying economy of any note, and that's what you get.

Anonymous Declares War Over Charlie Hebdo Attack 509

mpicpp writes with news that hackers claiming to represent Anonymous have declared war on terrorists. They pledged to take down websites and social media accounts being used by jihadists as retaliation for the Charlie Hebdo attack. They said, "It is clear that some people do not want, in a free world, this inviolable and sacred right to express in any way one's opinions. Anonymous will never leave this right violated by obscurantism and mysticism. We will fight always and everywhere the enemies of freedom of speech. ... Freedom of speech and opinion is a non-negotiable thing, to tackle it is to attack democracy. Expect a massive frontal reaction from us because the struggle for the defense of those freedoms is the foundation of our movement.

Bots Scanning GitHub To Steal Amazon EC2 Keys 119

New submitter juniq writes: As one developer found out, posting your Amazon keys to GitHub on accident can be a costly mistake if they are not revoked immediately.

"When I woke up the next morning, I had four emails from Amazon AWS and a missed phone call from Amazon AWS. Something about 140 servers running on my AWS account. What? How? I only had S3 keys on my GitHub and they where gone within 5 minutes! Turns out through the S3 API you can actually spin up EC2 instances, and my key had been spotted by a bot that continually searches GitHub for API keys. Amazon AWS customer support informed me this happens a lot recently; hackers have created an algorithm that searches GitHub 24 hours per day for API keys. Once it finds one it spins up max instances of EC2 servers to farm itself bitcoins."

Build a system that even a fool can use and only a fool will want to use it.
