Fermat's Library

Fermat's Library 23456789 is the largest prime number with consecutive increasing digits. > What about the reverse case? >> 98765431, though I like 98764321 better because it's 2 groups of 4 descending numbers

It's been under discussion on Hacker News all day... the conclus

It's been under discussion on Hacker News all day... the conclusion from people that specialize in materials science seems to be: Looks very much like they'd expect such a discovery to look - the graphs make sense, and in the video linked from the second paper, the material behaves as would be expected of a superconductor on a magnet. The numbers reported for conductivity and other properties are not ideal for a practical superconductor. Suspicion is that the initial samples suffer from crystal growth limitations and that if that is the case, getting better conductivity is mostly about better manufacturing methods The production process is dead simple, involves no exotic materials, and probably could be done in a garage. This appears to be precisely what's going on as I'm writing this, with labs and garage tinkerers (Applied Science, maybe?) alike racing to try to duplicate the material described in the paper. Because it's simple to make, we'll know very very quickly (tomorrow or later this week) whether this is a real ambient temp/pressure superconductor, because someone should be able to reproduce the paper's results. The notable thing about this material is that it exists and proves that room temp (actually above that, up to 127C) superconductors are possible. It may be possible to refine the material to become a practical superconductor itself, but the fact that this is possible AT ALL is mind blowing and worthy of a Nobel prize. Gonna be an interesting week.

英文报道来了:“上海警方的数据库被出售,这可能是中国有史以来最大规模的数据泄露”

英文报道来了:“上海警方的数据库被出售,这可能是中国有史以来最大规模的数据泄露” Shanghai police database for sale in what could be China’s biggest ever data breach A database purportedly containing information about one billion Chinese residents has been listed for sale on Breach Forums for Bitcoin, or approximately US$,. Attracting replies and , views within hours, the listing was posted a short time ago by an anonymous user named ChinaDan. “In , the Shanghai National Police (SHGA) database was leaked. This database contains many terabytes of data and information on Billions of Chinese citizens,” said the post. “Databases contain information on Billion Chinese national residents and several billion case records, including: name, address, birthplace, national ID Number, mobile number, all crime/case details.” The seller has provided what he claims is a sample data set, with , files from the database. The sample data has been uploaded to the forum’s servers. #China #databreach

Inherent complexity does not go away if you close your eyes.

Inherent complexity does not go away if you close your eyes. When you choose not to care about complexity, you're merely pushing it onto other developers in your org, ops people, your customers, someone. Now they have to work around your assumptions to make sure everything keeps running smoothly. And nowadays, I'm often that someone, and I'm tired of it. Because there is a lot to like in Go at first, because it's so easy to pick up, but so hard to move away from, and because the cost of choosing it in the first place reveals itself slowly over time, and compounds, only becoming unbearable when it's much too late, this is not a discussion we can afford to ignore as an industry. Until we demand better of our tools, we are doomed to be woken up in the middle of the night, over and over again, because some nil value slipped in where it never should have. It's the Billion Dollar Mistake all over again.
