Embedded Rust Hack Chat

May 10, 2021 by 18 Comments

Join us on Wednesday, May 12 at noon Pacific for the Embedded Rust Hack Chat with James Munns!

Programming languages, like fashion, are very much a matter of personal taste. Professional developers often don’t have much say in which language they’ll use for a given project, either for legacy or team reasons, but if they did have a choice, they’d probably choose the language that works best with the way they think. Some languages just “fit” different brains better than others, and when everything is in sync between language and developer, code just seems to flow effortlessly through the keyboard and onto the screen.

One language that consistently scores at the top of developers’ “most loved” lists is Rust. For a language that started as a personal project and has only existed for a little more than a decade, that’s really saying something. The emphasis Rust puts on safety and performance probably has a lot to do with that. And thanks to its safe concurrency, its memory safety, and its interoperability with C and other languages, Rust has made considerable in-roads with the embedded development community.

To learn more about Rust in embedded systems, James Munns will stop by the Hack Chat. James is an embedded systems engineer, with a history of working on software for a wide range of systems, including safety-critical avionics, and rapidly prototyped IoT systems. He’s a founding member of the Rust Embedded Working Group, as well as a founder of Ferrous Systems, a consultancy focused on systems development in Rust, with a specialty in embedded systems development. James also used to write for Hackaday, so he must be a pretty cool guy. So swing by the Hack Chat and find out where Rust might be able to help you out with your next embedded project.

join-hack-chatOur Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, May 12 at 12:00 PM Pacific time. If time zones have you tied up, we have a handy time zone converter.

Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io. You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about.

This Week In Security: Iran’s ITG18, ProcMon For Linux, And Garbage Collection Fail

July 24, 2020 by 4 Comments

Even top-tier security professionals make catastrophic mistakes, and this time it was the operators at Iran’s ITG18. We’re once again talking about the strange shadowy world of state sponsored hacking. This story comes from the IBM X-Force Incident Response Intelligence Services (IRIS). I suspect a Deadpool fan must work at IBM, but that’s beside the point.

A server suspected to be used by ITG18 was incorrectly configured, and when data and training videos were stored there, that data was publicly accessible. Among the captured data was records of compromised accounts belonging to US and Greek military personnel.

The training videos also contained a few interesting tidbits. If a targeted account used two factor authentication, the attacker was to make a note and give up on gaining access to that account. If a Google account was breached, the practice was to start with Google Takeout, the service from Google that allows downloading all the data Google has collected related to that account. Yoiks.

Mr. Trash Wheel Cleans Baltimore’s Harbor

October 14, 2015 by 40 Comments

Quite frankly we’re rather surprised we haven’t heard of Mr. Trash Wheel before. It’s a community project by the Baltimore Waterfront’s Healthy Harbor program where they are trying to make the harbor both swimmable and fishable by 2020. One of the coolest projects that resonates with us is Mr. Trash Wheel — a waterwheel-powered-trash-collecting-conveyor-belt. Say that 10 times fast!

It was built in early 2014, and according to the latest data it has removed a whopping 160 tons of garbage from the waterway already. Floating buoy-nets direct the garbage floating on top of the water into a narrow passage where the conveyor belt powered by a waterwheel slowly picks up the trash, and then deposits it into a large dumpster on a barge.

In fact, it’s even saved a python from the water too!
