Challenges of Big Data Analytics in High-Energy Physics
There are four key issues to overcome if you want to tame Big Data: volume (quantity of data), variety (different forms of data), velocity (how fast the data is generated and processed) and veracity (variation in quality of data). You have to be able to deal with lots and lots, of all kinds of data, moving really…

Displaying Dimuon Events from the CMS Detector using D3.js
I became a Python geek and GnuPlot maniac since I joined CERN around three years ago. I have to admit, however, that I really enjoy the flexibility of D3.js, and its capability to render histograms directly in the web browser. D3 is a JavaScript library for manipulating documents based on data. This library helps you to bring data to life…

CERN: Where Big Bang Theory meets Big Data Analytics
The volume, variety, velocity and veracity of data generated by the LHC experiments at CERN continue to reach unprecedented levels: some 22 petabyte of data this year, after throwing away 99% of what is recorded by the LHC detectors. This phenomenal growth means that not only must we understand Big Data in order to decipher…

bitcoin.de: Erster deutscher Marktplatz für Bitcoins
Bitcoins sind derzeit auch bei uns am CERN ein brandheißes Thema. Innerhalb weniger Wochen stieg der Wert eines Bitcoins (BTC) von 20 Cent im Dezember 2010 auf Größenordnungen von bis zu 30 Dollar. Dennoch lohnt sich das Mining kaum, zumindest nicht zu den aktuellen Strompreisen. Die Bitcoin-Börse bitcoin.de schafft hier nun Abhilfe! Ein gutes halbes…

CERN: The world’s first website went online 20 years ago today
On this day 20 years ago the world’s first website went live. The website, created by Tim Berners-Lee at CERN, was a basic text page with hyperlinks and went live on August 6, 1991. The website was hosted on Berners-Lees’ NeXT computer, the first web server ever, which had a note taped to the front…
