In less than two weeks the Maker Faire will come to Rome. It’s a 3-day gathering of makers, hackers, companies and hobbyists with the passion for electronics, programming, manufacturing, artistry, learning and creating. There will be some practical workshops, tons of lectures, and bigger talks called “cortocircuiti” (shortcircuits). It will be hosted in the University of La […]

TED talk on everyday cybercrime

September 17, 2013

0

The following talk by James Lyne is an interesting wake-up call. It’s a video that technology enthusiasts could share with anyone even if they’re not familiar with computer science. James executes, in real time, two practical examples of hacking, and also shows what data and statistics can be collected by scanning a room full of […]

JTAGWhisperer: Arduino as a XSVF programmer

February 5, 2012

0

Dangerous Prototypes features an interesting project, that is similar to my JTAGduino idea. JTAGWhisperer is a solution to program FPGAs and CPLDs using Arduino and a small client-side Python script. It reads files in the XSVF format, which stands for Xilinx Serial Vector Format and is one of the formats used to program Xilinx chips. […]

New Convergence notaries emerge

When I talked about Convergence (a new SSL paradigm that improves security while browsing HTTPS sites on Firefox) in this blog post, I noted that the system needed a kickstart to become effective. Luckily, new Convergence notaries start to emerge. SSL Labs now runs its own notary servers, here the details and the instructions to […]

Recently the main Linux website, kernel.org, was compromised by an hacking attack. Since then, Linus Torvalds decided to use GitHub as the master repository for the whole kernel (here the announcement), and kernel.org has been down for a long time. This has broken some of my old tutorials on this blog. In my tutorials, I […]

Convergence: fixing SSL security

September 4, 2011

Today I discovered how broken is the current situation for SSL, HTTPS and Certification Authorities (CA), thanks to a Reddit post about a “BlackHat USA 2011” 48-minutes presentation that is very entertaining to follow: SSL And The Future Of Authenticity “too long; didn’t watch” Here’s a quick summary. The speaker tells a story of a […]

Capturing an analog signal with Arduino and python

March 26, 2011

Last week I salvaged a magnetic sensor from a stationary bike and connected it to my Arduino Uno in order to analyze the sensor’s behavior with the ADC converters.   I wanted to capture a good enough signal, so I searched about the Arduino capabilities: From analogRead() reference description: It takes about 100 microseconds (0.0001 […]

Salvaging an old stationary bike RPM sensor

March 20, 2011

I had to dispose of an old stationary bike that little by little fell apart. Before throwing it away I wanted to see if I could salvage something from its simple electronics. The bike has a sensor that somehow detects the rotation of the crankset and then is used to display the RPM on a […]
