RTI Eliminates the HTTP Middleman
We’ve spent quite a bit of energy talking about various communication patterns for use in the Internet of Things (IoT). There’s the ever-popular publish/subscribe (P/S) for sending data around, and then there’s request/reply (R/R) for controlling devices.
And we’ve blithely referred to data being sucked into the Cloud for more processing before commands are sent back down to devices. But we haven’t looked in any detail at how data gets from the local infrastructure (perhaps a gateway) into the Cloud. It turns out that this is where two very different worlds meet, as described by RTI with their recent release of Connext DDS 5.2.
A Fish Fry Greatest Hit
What has your power supply done for you lately? In this week’s Fish Fry, we take a closer look at a revolutionary new technology that's taking power supplies by storm. My guest is Michael Freeman (CEO/CTO - Semitrex) and he’s here to introduce us to the power of the muxcapacitor and unveil how Semitrex plans to stem the tide of the world’s energy consumption...one power supply at a time. Also this week, we take a closer look at the newest rumors surrounding Intel's buyout of Altera.
From “Hello World” to Saving the World
After the EE Journal team’s inspiring and fascinating trip to last year’s World Maker Faire in New York, we were pumped this year to head out again to the New York Hall of Science in Queens for the 2015 World Maker Faire. Once again, the “Greatest Show (and Tell) on Earth” did not disappoint. We came away excited and energized and ready to tinker around with our own Arduino boards, 3D printers, robots, and quadcopters at home.
Without further ado, here are EE Journal’s Top 5 Favorite Things from World Maker Faire 2015:
Volkswagen and Beyond
We must not do this.
We are not soldiers.
We are not slaves.
Engineers are not mindless minions, obligated to serve at the whims of oppressive overlords. We are among the best and the brightest of humanity. For engineering is the one vocation that most separates humans from other species wandering the planet. Engineers are an exclusive and privileged fraternity instilled with the knowledge, skills, and passion to solve problems, to create things that have not existed before, and to make the world a better place.
Volkswagen’s Firmware Kerfuffle Highlights Engineering Responsibilities
“Will no one rid me of this troublesome priest?” – King Henry II [1133 – 1189], referring to Thomas Becket, Archbishop of Canterbury
In Grand Theft Auto V you can press LB, LT, RB, RT, Left, Right, Left, Right, Right to fly like Superman. Or, in Plants vs. Zombies, you can type the word “future” to give the zombies funny 3D glasses. If you enter the correct cheat code on your PlayStation 4 you can change the players’ jerseys in NBA2K14. But on a Volkswagen Jetta you just have to take it to the shop to get smog tested.
Which Designers Need to be Schooled?
A simple, straightforward EDA whitepaper recently got me asking some demographic questions. The answers say something about where analog and digital designs are being done – and where they’re coming together. (And yes – sorry, but the Internet of Things (IoT) is involved.)
Whitepapers are popular these days. Nothing new about the whitepaper concept, but how many of them get written during a given period of time (shall we call it the “whitepaper density”?) varies with the economic cycle. And the density is high at the moment.
Whitepapers can be a really useful way to get a technical message out without it sounding like marketing – if done right. You can talk about your product, unlike in an editorial article. But if you keep the tone analytical and professional, it doesn’t come across as marketing. You hold back on the, “OUR PRODUCT EFFING ROCKS” enthusiasm. More like, “Given these numbers and the trends in the industry, there’s a high likelihood that our product would be perceived as effing rocking.”
