Embedded Linux Takes to the Skies (Video) 25

Posted by Roblimo
from the robot-drones-want-you-to-take-them-to-your-leader-(beep) dept.
This is an interview with Clay McClure. He makes his living designing 'custom Linux software solutions for technology start-ups in Atlanta and the San Francisco Bay area.' He also works on Embedded Linux for autonomous drones. Here's a link to slides from a talk he gave on exactly that topic: Flying Penguins - Embedded Linux Applications for autonomous UAVs, and that's far from all he has to say about making Linux-controlled drones. However, for some reason Timothy and Clay didn't talk about using drones for target practice. Perhaps they can discuss that another time.

NOTE: We urge you to read the transcript of this interview even if you prefer watching videos; it contains material we left out of the video due to sound problems.

IT Consultant Talks About 'Negotiating for Nerds' (Video) 61

Posted by Roblimo
from the paying-it-forward dept.
Matt Heusser did a Slashdot video interview back in 2013 titled How to Become an IT Expert Companies Seek Out and Pay Well. Despite noise from a few yammerheads about Matt getting 'free advertising' on Slashdot, which is unlikely since the vast majority of Slashdot users are more likely to compete with him than to hire him, most of the people who saw that video (or read the transcript) knew he was giving helpful advice to peers who might want to get out of the cubicle and work for themselves.

Today, Matt is with us again. This video is about 'Negotiating for Nerds.' Matt talks about negotiating a pay raise or consulting fee increase, starting with learning who has the actual power to negotiate with you. This is essential knowledge if you are employed (or self-employed) in IT and want to make sure you're getting all you are worth.

Another 'Draw Your Own Circuits' System at SXSW (Video) 27

Posted by Roblimo
from the is-this-an-easy-way-to-connect-the-'rear'-speakers-in-your-home-theater-system? dept.
While Timothy Lord was at SXSW, he chatted with Yuki Nishida of AgIC and learned about the company's conductive ink products. But AgIC wasn't the only company at SXSW showing off conductive ink. You could also meet the Electroninks people and see their Circuit Scribe product, which had a Kickstarter campaign a while back that raised $574,425.

This kind of product seems to be attractive to the kind of people who fund Kickstarter projects, and this bunch seems to have good resumes and some interesting, well thought-out products. There is apparently room in the 'draw circuits and learn electrical basics' market for both AgIC and Electroninks -- and probably for another dozen competitors, too.

Armstrap Claims to Make ARM Prototyping Easier (Video) 41

Posted by Roblimo
from the not-just-easy-but-fun-too dept.
It almost seems too perfect that the originator of the Armstrap 'community of engineers and makers' is named Charles Armstrap. He just introduces himself as 'Charles' on the Armstrap.org website. Names aside, Armstrap.org is 100% open source, including circuit board designs. This is not a 'draw your own circuit boards' bunch, although you certainly could if you wanted to badly enough since they provide schematics and even full CAD drawings of what they make. The reason they do this is laid out on their Core Values page. The boards Armstrap sells are not expensive, but if you are going to be truly open source, you need to supply the means to duplicate and modify or extend your work, as is totally permitted under the MIT License they use.

How to Prepare for an IT Security Disaster (Video) 23

Posted by Roblimo
from the 2-ounces-of-prevention-are-worth-32-ounces-of-cure dept.
What should you do if your company's servers are hacked and your customers' credit card info or other data are stolen? Neill Feather, president of SiteLock, says you should have a plan of action tested and ready to go, the same way it's wise to hold fire drills so that everyone knows what to do in case of fire. Neill also recommends checking out the Online Trust Alliance and the many resources it makes available to businesses of all sizes whether or not they are OTA members. One document that would be a good place to start is their Data Protection & Breach Readiness Guide, which covers topics including liability and insurance considerations; basic forensics (to help catch the evildoers -- and prevent them from doing evil to you again); and even what information you should include in a letter to customers after a Target or Home Depot-type data theft. We can sum all of this up with the old saying, 'An ounce of prevention is worth a pound of cure,' but you should also know what to do if a problem happens, whether that problem is data theft, a ransomware attack or anything in between.

Hand-Drawn and Inkjet Printed Circuits for the Masses (Video) 33

Posted by Roblimo
from the give-your-kids-paper-plates-with-lights-that-tell-them-to-eat-their-veggies dept.
We started looking at ways to make instant hand-drawn or inkjet-printed circuit boards because Timothy met an engaging young man named Yuki Nishida at SXSW. Yuki is a co-founder of AgIC, a company that makes conductive ink pens and supplies special paper you can use to write or draw circuits or, if you have the right model of Brother printer, to print them with special inkjet inks. The AgIC people are aggressively putting the 'A' in STEAM by marketing their products to artists and craftspeople. Indeed the second line on their website's home page says, 'AgIC offers handy tools to light up your own art works.' This is an excellent niche, and now that AgIC has developed a circuit eraser (due to ship this April), it may lead to all kinds of creative designs. And as is typical with this kind of company these days, AgIC has been (at least partly) crowdfunded.

A little cursory Google searching will soon lead you to other companies selling into the home/prototype circuit board market, including Cartesian Co and their Argentum 3-D printer that does prototype and short-run PCBs and only costs $899 (on special at the time this was written) and Electroninks, which markets the Circuit Scribe pen and associated materials with an emphasis on education. There are others in this growing field, and a year from now there will probably be more of them, all working to replace the venerable breadboard the same way electronic calculators replaced slide rules.

Dueling Home Automation Systems at SXSW (Video) 47

Posted by Roblimo
from the to-serve-man dept.
Austin has a strong western heritage and more country and western music than you can shake a fiddle bow at. So when Timothy came back from SXSW with video clips from two home automation companies with different approaches to this question: "How can you work with a whole bunch of lights and thermostats and other IoT home automation pieces that all have different OSes and control APIs?" we obviously had to call the resulting video 'Dueling Home Automation Systems.'

The two companies shown in this video are called WigWag and Yonomi. WigWag sells you a "Relay," which they say "is a powerful mini computer that gives you control of your home's smart devices." The minimum pre-order buy-in for WigWag seems to be a $149 WigWag Relay. Their 'products' page his page shows the Relay -- and many other gadgets and kits that could easily run your total tab up to $1000 or more. Yonomi, on the other hand, "resides on your phone and in the Cloud. No need for a hub, controller box or other additional hardware. Yonomi magically finds and enhances your existing connected devices allowing them to interact with one another in ways never before possible."

Yonomi may start with a free Android app (iOS coming soon), but you still need to buy lights, speakers, thermostats, and other things that are Internet-aware, so you're not going to save much (if anything) over buying a WigWag relay and the rest of what you need to create your own, private Internet of Things. And what about good old X10 and other home control systems? They're still out there, still doing their thing in millions of homes even if they aren't getting all the IoT buzz. In any case, it's nice to see new home automation alternatives coming down the pike, even if their cloudness may make them easier to hack than an old-fashioned appliance like this coffeemaker.

How 'The Cloud' Eats Away at Your Online Privacy (Video) 86

Posted by Roblimo
from the it-seems-the-network-is-the-computer-after-all dept.
Tom Henderson, Principal Researcher at ExtremeLabs Inc., is not a cloud fan. He is a staunch privacy advocate, and this is the root of his distrust of companies that store your data in their memories instead of yours. You can get an idea of his (dis)like of vague cloud privacy protections and foggy vendor service agreements from the fact that his Network World columnn is called Thumping the Clouds. We called Tom specifically to ask him about a column entry titled The downside to mass data storage in the cloud.

Today's video covers only part of what Tom had to say about cloud privacy and information security, but it's still an earful and a half. His last few lines are priceless. Watch and listen, or at least read the transcript, and you'll see what we mean.

Project an Interactive Game on Your Floor or Wall (Video) 57

Posted by Roblimo
from the bounce-it-on-the-floor-or-bounce-it-on-the-wall dept.
Lumo is an interactive projector. You can use it to bore people with PowerPoint slides or you can use it as a game machine. It has a built-in (low res) camera that can detect a kick (as shown at the beginning of the video) and make a (virtual) ball move as a result of that action. 'But,' you ask, 'do they have an Indiegogo campaign?' Not yet. It launches on March 23.

The Lumo projector was originally designed for commercial use at children's museums and as a trade show attention-getter -- at $10,000 a pop. The consumer version is expected to cost less than $500, according to Lumo CEO (and Slashdot interviewee) Meghan Athavale. And while she doesn't talk much about it in the interview, if you already have a computer, a projector, and a Kinect or webcam, you can buy the a stripped-down version of the company's 'interactive-floor-wall projection' software for $39, plus games or customizable game templates.

You Don't Need to Start as a Teen to be an Ethical Hacker (Video) 56

Meet Justin Whitehead. While a lot of his contemporaries were going to college, he became an Airborne soldier. After that he went to college, became an IT technian, got some experience as a Computer Forensic Analyst, and met people who looked like they were having a good time as penetration testers. So he took some recommended classes,got hired by One World Labs, and last week at B-Sides Austin, he and coworker Antonio Herraiz gave a talk titled 'Spanking the monkey/How pen testers can do it better.

Justin is 40, an age where a lot of people in the IT game worry about being over the hill and unemployable. But Justin's little video talk should give you hope -- whether you're a mature college student, have a stalled IT career or are thinking about a career change but want to keep working with computers and IT in general. It seems that there are decent IT-related jobs out there even if you're not a youngster; and even if you didn't start working with computers until you were in your 20s or 30s.
It's funny.  Laugh.

from the not-everything-is-about-money dept.
In February we ran a video titled Rich Olson Embodies the Spirit of the Maker Movement. We aren't saying Rich is a superman, but more like everyman or, in this case, everymaker. He is a hobbyist who, like many others, shares his designs freely in the best spirit of open source. Today we have some more words from Rich that may help you if you are just starting to use a 3-D printer and similar tools either at home or in a makerspace. and a note: If you know someone we should interview, please email robinATroblimoDOTCOM.
