On Sunday night the WikiLeaks-style group Distributed Denial of Secrets is revealing what it calls GabLeaks, a collection of more than 70 gigabytes of Gab data representing more than 40 million posts. DDoSecrets says a hacktivist who self-identifies as "JaXpArO and My Little Anonymous Revival Project" siphoned that data out of Gab's backend databases in an effort to expose the platform's largely right-wing users. Those Gab patrons, whose numbers have swelled after Parler went offline, include large numbers of Qanon conspiracy theorists, white nationalists, and promoters of former president Donald Trump's election-stealing conspiracies that resulted in the January 6 riot on Capitol Hill.

A digital photo frame is a small screen that can sit on your desk in your office or in your kitchen displaying your favorite pictures, changing at regular intervals. The first commercial digital photo frame was introduced in the 1990s shortly after the digital camera. Digital photo frames made a comeback in popularity during 2020, perhaps because people were staying at home more. In this tutorial, we’ll turn our Raspberry Pi into a digital photo frame using MagicMirror and the GooglePhotos module. Please note, we will skip installation of the 2-way mirror in the original Magic Mirror project. Consider this project, “Magic Mirror, without the mirror.” Read How to Build a Raspberry Pi-Powered Digital Photo Frame via Tom's Hardware An interesting link found among my daily reading

Coding can seem scary at first - but it's actually not that hard! Let's learn how to program in C#.

During my Track and Field training sessions, my coach often expressed his desire to have a more precise way of measuring an athlete's performance. However, living in a third-world-country means that shipping from the US is expensive and sports clubs and educational institutions do not have precise timing systems as a funding priority. I had been working on line-follower robots with Arduino for some time, so I realized that an affordable, wireless and precise laser gate timing system made of easy to find components should be possible. Accounting for the different prices across the world, absolutely all of the components and parts needed for the complete system should cost around 100USD. This is a major price difference with other systems, considering that it has a very decent precision and has a wireless range that exceeds almost any Track and Field oval in the world. The system consists of two finish line modules and one start line module. Read A wireless timing system for

BrachioGraph - arm-writer - is an easy-to-build pen-plotter, driven by a library of simple Python applications.A BrachioGraph can be built in an hour or so without any special skills. The total cost of all components can be as low as €15 or so. Apart from a Raspberry Pi computer and some hobby servo motors, the plotter can be built with everyday household items such as a clothes-peg. The software in the BrachioGraph library includes code to drive the hardware and vectorise bit-map images.

After a thorough cleaning, most of the innards of the SNES controller had to be hollowed out to fit the LCD while still holding the controls in place. Josh0O0 used the LCD from a Waveshare Tiny GamePi15, which measures just 1.54" diagonally and has a perfect 4:3 aspect ratio, to display games. The LCD happened to fit right where the Start and Select buttons on the SNES controller normally reside. That meant moving those buttons to the bottom of the controller to retain functionality, but just about everything else from the controller appears to be standard. To get the Raspberry Pi Zero to fit, almost all of the surface-mounted ports had to be removed. Josh0O0 retained the micro USB port, though, because it's necessary to charge the built-in 600 mAh battery, which lasts between one and two hours. While the first video doesn't show the completed device, it appears that the LCD and battery attach to the Tiny GamePi15. Josh0O0 cut down the GPIO pins on the Waveshare device

This is an important reminder that your technology work can have dramatic consequences far outside your original plans. We need to think ethically about technology as well. — Douglas NBC News reports:A number of pro-Trump extremists used Facebook to plan their attack on the U.S. Capitol, a watchdog organization has found, contradicting claims by Facebook's leadership that such planning was largely done on other sites. Private Facebook groups spent months advising one another about how to "take down" the U.S. government, particularly after Joe Biden was elected president, according to a report from the nonprofit Tech Transparency Project, which tracked several of them. Many of the groups specifically talked about traveling to the Capitol on Jan. 6, the date Congress counted the electoral votes that affirmed Biden's victory."Calls to 'occupy Congress' were rampant on Facebook in the weeks leading up to the deadly Capitol riot, making no secret of the ev

Ivan Miranda has come up with a novel method for drawing messages in the sand, using a tread assembly that prints as it travels along the beach. The robot uses a length of square tubing to connect a pair of half tanks, with 50 SG90 micro servos spaced out on the bottom. As it pulls itself, the motors are controlled with a total of three Arduino Mega boards, intermittently extending into the sand. This creates lines that combine to form individual letters.
