[SANS ISC] Obfuscated bash script targeting QNap boxes

Posted on by

I published the following diary on isc.sans.edu: “Obfuscated bash script targeting QNap boxes“: One of our readers, Nathaniel Vos, shared an interesting shell script with us and thanks to him! He found it on an embedded Linux device, more precisely, a QNap NAS running QTS 4.3. After some quick investigations,

Arduino Gets a Command Line Interface

Posted on by

When using an Arduino, at least once you’ve made it past blinking LEDs, you might start making use of the serial connection to send and receive information from the microcontroller. Communicating with the board while it’s interacting with its environment is a crucial way to get information in real-time. Usually, that’s as far as it goes, but [Pieter] wanted to take it a step farther than that with his command line interpreter (CLI) for the Arduino.

The CLI allows the user to run Unix-like commands directly on the Arduino. This means control of GPIO and the rest of the features …read more

Launching Fireworks with Raspberry Pi this Fourth of July

Posted on by

It’s that time of year again in the United States, and the skies will soon be alight with pyrotechnic displays, both professional and amateur. Amazing fireworks are freely available, sometimes legally, sometimes not. For the enthusiasts that put on homebrew displays, though, the choice between watching your handiwork or paying attention to what you’re doing while running the show is a tough one. This Raspberry Pi fireworks show controller aims to fix that problem.

[netmagi] claims his yearly display is a modest affair, but this controller can address 24 channels, which would be a pretty big show in any neighborhood. …read more

Linux-Fu: Keeping Things Running

Posted on by

If you’ve used Linux from the early days (or, like me, started with Unix), you didn’t have to learn as much right away and as things have become more complex, you can kind of pick things up as you go. If you are only starting with Linux because you are using a Raspberry Pi, became unhappy with XP being orphaned, or you are running a cloud server for your latest Skynet-like IoT project, it can be daunting to pick it all up in one place.

Recently my son asked me how do you make something run on a Linux box …read more

These Sands Of Time Literally Keep Time

Posted on by

Hour glasses have long been a way to indicate time with sand, but the one-hour resolution isn’t the best. [Erich] decided he would be do better and made a clock that actually wrote the time in the sand. We’ve seen this before with writing time on a dry erase board with an arm that first erases the previous time and then uses a dry erase marker to write the next time. [Erich]’s also uses an arm to write the time, using the tip of a sea shell, but he erases the time by vibrating the sandbox, something that took much …read more

Revel Systems inks payments deal with Shell as rumors swirl of a sale to IBM

Posted on by

14807800057_06db2ece9e_k Reports claim that point of sale startup Revel Systems is in early acquisition negotiations with IBM, and while both Revel and IBM declined to comment when we asked about it, a deal that the startup announced today could provide an interesting clue for why a company like Big Blue might be interested in buying it. Today Revel announced a deal with Shell, the oil and gas giant, to implement… Read More Continue reading Revel Systems inks payments deal with Shell as rumors swirl of a sale to IBM→

One Man, A Raspberry Pi, and a Formerly Hand Powered Loom

Posted on by

[Fred Hoefler] was challenged to finally do something with that Raspberry Pi he wouldn’t keep quiet about. So he built a machine assist loom for the hand weaver. Many older weavers simply can’t enjoy their art anymore due to the physical strain caused by the repetitive task. Since he had a Pi looking for a purpose, he also had his project.

His biggest requirement was cost. There are lots of assistive looms on the market, but the starting price for those is around ten thousand dollars. So he set the rule that nothing on the device would cost more than …read more
