Following on the heels of Mirai, a family of malware exploiting Internet of Things devices, [Sam Edwards] and [Ioannis Profetis] of Rapidity Networks have discovered a malicious Internet worm dubbed Hajime which targets Internet of Things devices.
Around the beginning of October, news of an IoT botnet came forward, turning IP webcams around the world into a DDoS machine. Rapidity Networks took an interest in this worm, and set out a few honeypots in the hopes of discovering what makes it tick.
Looking closely at the data, there was evidence of a second botnet that was significantly more sophisticated. Right now, they’re calling this worm Hajime.
In what might be one of the coolest applications of laser cutting, joinery, puzzles, writing, and bookbinding, [Brady Whitney] has created the Codex Silenda — a literal puzzle book of magnificent proportions.
[Whitney] had originally conceived the idea of the Codex for his senior thesis research project at Iowa State University, and the result is something for almost everyone. On each of the Codex’s five pages lies a mechanical puzzle that must be solved to progress to the next, while an accompanying text weaves a story as you do so. These intricate pages were designed in SolidWorks and painstakingly assembled from laser cut wood. Breaking the fourth wall of storytelling by engaging the reader directly in uncovering the book’s mysteries is a unique feat, and it looks gorgeous to boot.
Yes, yes. We all love to laugh at a technology in its infancy. It’s like when robots fall down: it’s a cheap shot and things will surely get better, right? Indeed, the Guardian has had its fun with this particular WiFi kettle before — they’re British and nothing is more important than a remote-controlled cuppa.
Every time we hear about one walled-garden protocol not speaking to another, and the resulting configuration mayhem that ensues, we can’t help think that [Mike] was right: home automation has a software problem. But that’s putting the blame on the technology. (We’re sure that [Mark] could have made the kettle work if he’d just applied a little Wireshark.)
There’s another mismatch here — one of expectations about the users. A water kettle is an object that should be usable by grandmothers, and a complex networked device is clearly aimed at techies and early adopters. Combining the two is asking for trouble. Non-functioning IoT devices are the blinking 12:00 of our generation.
What do you think? Where’s the blame here? Poor design, bad software stack, stupid users, or failure of mega-corps to integrate their systems together? More importantly, how could we make it better?
Looking at the ingredient list of some popular processed foods will produce a puzzled look on the typical hacker’s face. Tricalcium phosphate, thiamine mononitrate, zinc proteinate, pyridoxine hydrocloride… just who the hell comes up with these names anyway? It turns out that there is a method to the madness of chemical name structures. Some of them are well known, such as sodium chloride (NaCl) and hydrogen peroxide (H2O2). Others… not so much. In the early years of chemistry, chemical substances were named after their appearance, affects and uses. Baking soda, laughing gas and formic acid (formic is Latin for ant, and responsible for the sting in an ant bite) to name a few. As more and more chemical substances were discovered over time, a more structured naming convention was needed. Today, the above are known as sodium bicarbonate (NaHCO3), nitrous oxide (N2O) and a type of carboxylic acid (R – COOH, think of the “R” as a variable) respectively.
In today’s article, we’re going to talk about this naming structure, so that next time you admire the back of soup can, you won’t look so puzzled. We’ll also cover several common definitions that every novice biohacker should be familiar with as well.
Like all our meetups, we’ve gathered some of the neatest technologists to spill the beans on what they’re doing and how they’re doing it. Madison Maxey, founder of Loomia and designer of soft, blinky circuits will be there. Dr. Ellen Jorgensen, co-founder and executive director of Genspace, the citizen science biotech ‘hackerspace’ in the heart of New York will be there too. Kari Love & Matthew Borgatti of Super-Releaser, most famous for their super cute pneumatic soft robots will also be there. It’s still up in the air if we’ll be racing these robots. Of course there will also be opportunities for you to present a lightning talk at the meetup.
A lot of people have already signed up for the Show and Tell but we do still have some time left for your project. Email sophi@hackaday.com to get on the list.
The “Navigation Thing“ was designed and built by [Jan Mrázek] as part of a night game activity for high school students during week-long seminar. A night-time path through a forest had stations with simple tasks, and the Navigation Thing used GPS, digital compass, a beeper, and a ring of RGB LEDs to provide a bit of “Wow factor” while guiding a group of students from one station to the next. The devices had a clear design direction:
“I wanted to build a device which a participant would find, insert batteries, and follow the beeping to find the next stop. Imagine the strong feeling of straying in the middle of the night in an unknown terrain far away from civilization trusting only a beeping thing you found. That was the feeling I wanted to achieve.”
The Navigation Things (there are six in total) guide users to fixed waypoints with GPS, a digital compass, and a ring of WS2812 LEDs — but the primary means of feedback to the user is a beeping that gets faster as you approach the destination. [Jan] had only four days to make all six units, which was doable. But as most of us know, delivering on a tight deadline is often less about doing the work you know about, and more about effectively handling the unexpected obstacles that inevitably pop up in the process.
Today’s engineers are just as good as the ones that came before, but that should not be the case and there is massive room for improvement. Improvement that can be realized by looking for the best of the world to come and the one we left behind.
Hey kids! Let’s learn why the CE certifications exist!
Survivorship bias is real. When we look at the accomplishments of the engineers that came before us we are forced to only look at the best examples. It first really occurred to me that this was real when I saw what I still consider to be the most atrocious piece of consumer oriented engineering the world has yet seen: the Campbell’s soup warmer.
This soup warmer is a poor combination of aluminum and Bakelite forged into the lowest tier of value engineering during its age. Yet it comes from the same time that put us on the moon: we still remember and celebrate Apollo. It’s possible that the soup warmer is forgotten because those who owned it perished from home fires, electrocution, or a diet of Campbell’s soup, but it’s likely that it just wasn’t worth remembering. It was bad engineering.
In fact, there’s mountains of objects. Coffee pots whose handles fell off. Switches that burned or shocked us. Cars that were ugly and barely worked. Literal mountains of pure refuse that never should have seen the light of day. Now we are here.
The world of engineering has changed. My girlfriend and I once snuck into an old factory in Louisville, Kentucky. The place was a foundry and the only building that survived the fire that ended the business. It happened to be where they stored their professional correspondence and sand casting patterns. It was moldy, dangerous, and a little frightening but I saw something amazing when we cracked open one of the file cabinets. It was folders and folders of all the communication that went into a single product. It was an old enough factory that some of it was before the widespread adoption of telephony and all documents had to be mailed from place to place.
