My wife, Claire, and I have been members of the Planetary Society since its founding in 1980. I was fortunate to be working at The Jet Propulsion Laboritory when Carl Sagen, Bruce Murray and Louis Friedman founded the society. Bill Nye, “The Science Guy” and space advocate, is now CEO. The society’s mission has changed […]

[UPDATE: 26 August 2017 – The binaries referenced in this post only work with Raspbian Jessie! If you have upgraded to Raspbian Stretch on a R-Pi 3 or R-Pi 3B+, get the newer binaries] The mongoDB documentation at mongodb.com states that 32-bit binaries are deprecated with release 3.2 and will be unavailable in future releases. The

I’m a big fan of MongoDB but contrary to its “humongous” orientation, I like to think small as in ARM-based SBCs like the Raspberry Pi or ODROID-C2 and DBs under a terabyte 😉 You can get a lot of power out of tiny inexpensive computers and USB disk drives! You can find my blog entries,

The Apache Software Foundation has released CouchDB version 2.0. CouchDB 2.0, is a “distributed” version of CouchDB, a mature NoSQL, document-oriented data-store that is accessable via a RESTful JSON API. Developers can take advantage of CouchDB’s offline capability and reliable data sync for web, mobile and IoT apps at (any) scale. [NOTE: September 2017 — CouchDB

We had a really old alarm clock in our bedroom. Really old. The LED number segments, which were a nice dim red in color, had been dying at the rate of 1 segment a year and it was getting hard to read the time. My wife finally had enough of my “I’ll get a new

I use MongoDB as my database of choice as you can tell by my blog entries. Under current Raspberry Pi OSs, MongoDB is limited by 32 bit binaries. Databases are restricted to 2GB. The Raspberry Pi 3 sports an ARMv7 processor that supports 64 bits. At this time (May 2016) there is no official OS

I’ve written about getting MongoDB running on the Raspberry Pi 2. View my other posts where you can get binaries (3.0.9) or learn how to compile from scratch (3.0.7). The mongo shell works great but you may want/need to code in Python, especially for device control or data logging, etc. PyMongo is a Python distribution containing

I’ve received feedback that some folks are having problems compiling MongoDB 3.0.7 per my instructions AND it takes a long time 😉 MongoDB 3.0.9 just became available but needs quite a few changes to source in order to compile on the Raspberry Pi. I worked through MongoDB build scripts for ARCH ARM Linux and managed to

I have successfully compiled MongoDB version 3.0.7 and tools on the Raspberry Pi 2. Full instructions are after the break — click on “more“. As usual I found great help from the Linux community for getting this to work on ARM7. mongo, mongod, mongos, and tools are all working great. The WiredTiger Engine does NOT work

I had been experimenting with the world of Javascript on the server-side using Node.js. I “fell off the horse” when Node.js had an identity and direction crisis and io.js was forked. Node.js and io.js have reunited and the latest supported version is v4.2 with v5.0 just released. The latest “apt-get” version of Node.js as of 15
