Bots Arrive

On Monday I received an Amazon Echo.  I am impressed.  "Alexa" is the keyword that gets the Echo's attention and it works near flawlessly.  You can barge-in, get Alexa's attention,  any time, even when the Echo is playing music.  The speech recognition works well in our large kitchen, even with  water running!  It is limited in its range of tasks at this time, but they are sufficient to make it worthwhile.  The music quality is fine, especially for an aging tin ear.  Although Siri does much better in search, I am really impressed by the Echo's speech recognition which is better than Siri's due in part, I am sure, to the 7 microphones.  I also am interested to see how Amazon uses the echo app in conjunction with the Echo device.  Currently the app logs your interactions with the Echo. Also  folks have hacked the API!  If you come across it in a friend's house, Alexa deserves a talking to!

  

My experience with Alexa has me thinking more about home bots.  Not all robots need to be mobile and my suspicion is that Alexa like entities will become more common in our homes earlier than Rosie like entities. It seems to be a natural transition to go from our smart phone based, social media and search engine interactions to an ambient bot that provides the same functionality by saying "Alexa."

I am still struggling with my copter but I did get software updates into it and learned a bunch about the arduino.  May have to set for a while as I crank up my iBeacon and other Bluetooth low energy devices. More on that in a future post.  Later!

 

Anyware

I just completed reading an article from O'Reilly by Mike Barlow, "When Hardware Meets Software."  It is short and free and does a great job of framing perhaps one of the next technological revolutions.  It makes at least three key points:  (1) hardware is beginning to achieve the same speedup in product realization that software has experienced using similar techniques, (2) hardware and software will be more equal partners in the future, and (3) software has  to raise the bar on quality, security, reliability, (name you favorite "ility"), internet quality of service is simply not good enough for the combination.

What does this say about the next generation of software engineers and especially hackers? They have to be as well versed in hardware too!  I think the hacker culture still retains it to a certain extent but not as completely as early Ham Radio enthusiasts or the Byte generation that had no choice but to pick up a soldering iron in order to do their software.

This next wave is a good thing.  Just as the rise of social media increased how connected we were to each other.  The rise of the Internet of Things/Industrial Internet/ Internet of Everything/Cyber Physical Systems will provide us with an appreciation of the  things around us, how they work and what they provide.  Great reading for my train ride to Hoboken!

I spent the weekend building some lego and trying to coax a mini-quadcopter to life.  Sadly it is not connecting to my iPhone so a new version of the software is in order. Double sadly I am struggling with earlier versions of Java related to earlier version of the arduino IDE. Hopefully progress this week and the next post will have a video of my success. Later!

Culture Mapping of Higher Education

We are all struggling to understand how we can convey the joy and excitement of technology to our children.  I have been involved at modest efforts focusing on grade school and high school students, some of which is chronicled at my aarphacker site.

Tim Stock and Marie Lena Tupot are focusing on using technology to understand what is available for students and using culture mapping and college syllabi to map and interrelate courses.  What a concept, to understand what is available and how it relates. They have a kickstarter to accelerate this mapping and I just stumbled across it with less than twenty hours to go.  So I am asking you if you read this on January 2nd would you please check out their kickstarter and hopefully back it and hopefully let others know.  Thanks!

I did not meet my resolution of last year for more posts but in 2015 I hope to average a post a week.  It has some probability of success since much of what I am doing in my new gig (Industry Professor at Stevens) will hopefully be of interest.  I am redoing my previous udoo benchmarks and am working on some items from kickstarter, so hopefully more soon.  The best to all of you in 2015, later!

Context and Cities

I just read a book, The Responsive City, by Stephen Goldsmith and Susan Crawford that I highly recommend.  First, it provides great case studies on how apps and analytics could transform city services and the relationship between city government and citizens. But the book is so much more.

In particular many of the case studies relate to what some folks are calling contextual computing(see for example, Age of Context: Mobile, Sensors, Data and the Future of Privacy, by Robert Scoble and Shel Israel.  To begin their foreword they provide a great Nicholas Negroponte quote, "Computing is not about computers any more.  It is about living."    They define five technologies as forming contextual computing: mobile devices, social media, big data, sensor and location based services.  More on the Age of Context  after I finish it, back to The Responsive City.

More broadly I think The Responsive City  is of general interest to anyone interested in understanding what is involved in introducing technology and building high tech systems. The principles noted are as timeless as those provided in Fred Brooks, Mythical Man Month. Some examples: (1) you not only introduce a system but change the process and empower employees, (2) management support is essential (3) user driven is key - test the apps in actual use (4) be mindful of privacy (5) work within the system but often with a small number of folks outside the system. I could go on but hopefully you get the idea and each is supported by several case studies.  Well worth the read for understanding city hall's side of smart cities and for understanding the general issues with introducing new technologies especially contextual systems.  This goes way beyond the Internet of Things or Cyber-Physical systems and the issues it addresses will greatly contribute to the success of such systems.  Highly recommended!

I have been away for awhile but hope to ramp up my posts as the year closes.  My goal is one per week until the end of the year.  Later!

Active STEM

This was my summer of STEM (Science, Technology, Engineering and Math).  First, with Matt Amoroso as my TA,  I taught six workshops at Stevens for their ECOES (Exploring Career Opportunities in Engineering and Science) program.  The workshops were three hours, half lecture and half workshop. Workshops were with raspberry pis, a breadboard and exercises.  The programming language was Python.  The high school students had variable experience in computer science, only about a quarter were active programmers.  Nonetheless the labs worked well with some tuning through the summer.  A later post will discuss some of these experiences.

We reprised this experience at r00tz, a spin off  workshop at DEF CON, with mostly grade school students.  The labs held up, especially the first few, and it was nice to see parents becoming absorbed too.

I am making the labs available on my new homepage, aarphacker.com.  I am adding resources and code to this site over the next few weeks and will keep you posted on the progress.  You are free to use any materials on the site with attribution and the promise that if you improve it you wil let me know so I can incorporate it in future versions.  Later!

Death and Bits

I have posted a few blogs on how to prepare your digital property for your demise.  This includes surveying the large ebook providers, commenting on Google's excellent and ground breaking policy and referring you to articles discussing the topic. 

Well another article surfaced today that discusses the topic and how friends and relatives potentially can be in trouble for taking possession of your friend or relatives bits.  Anne Flaherty does a great job in her article, much of the information is complimentary to what has been discussed in this blog.  So take a look at it now or bookmark it to return when you need it.  I hope that day is far away!

I will continually come back to this topic and hope you find the compendium of articles, knowledge and research useful.

Next blog on my summer of STEM with pointers to all the materials.  Later!

Of Course(s)

I have been teaching courses for an Executive Master's in Technology Management at the University of Pennsylvania, EMTM, since 2004.  This is the last year of the program and I decided to provide all my class notes on the web.  The class notes are for three courses: Software engineering, security and privacy in IT and human computer interaction. They can be found at my personal web site.  I hope you find it useful.

Some statistics from my involvement int he program: taught 26 trimesters involving 126, 3 hour lectures.

I hope you enjoy the material.  More posts soon, I have a backlog finally.  Later!
