One more day in Kansas City. One of my stops was the Negro Leagues Baseball Museum, in the same building that also houses the American Jazz Museum. I paid $15 to see both, and thought it was money well spent. I stayed for several hours just looking and reading, especially in the baseball museum.
It’s packed with a lot of history, much of it made during my lifetime. I came across an entry for Hank Aaron (“Hammerin’ Hank”). He started playing for the Boston Braves a year before I was born. He came to Atlanta with the then Milwaukee Braves in 1966 (the Boston Braves became the Milwaukee Braves became the Atlanta Braves). From that point I kept up with him and the team.
The museum didn’t allow photography in the museum proper, and I understand that. My few photos are of the street exterior and the foyer.
After a few hours just soaking in the NLBM I meandered a bit around the city, enjoying the late afternoon sunshine and the balmy 65° weather. And then I drove back to the hotel and supper.
My work with the Raspberry Pi started with the original Raspberry Pi 1 model B, the version that came with just two USB ports and the most amount of RAM at the time, 512MB. I purchased the B+, and then earlier this year, the Raspberry Pi 2 Model B. During all that time I’ve run some distribution of Linux on it; Arch first and for the most amount of time, then Raspbian when Arch suddenly corrupted itself after what turned out to be an ill-advised update on the B+.
If you look at the entries in this blog under Raspberry Pi you’ll note that it’s been for the most part light weight and a way to get to know how the hardware and software work together. I’ve looked up and followed along, making changes necessary for it to work on my end. I’ve not published anything unique that advanced the use of the Raspberry Pi. My excuses boil down to lack of time to really research and then apply what I’ve learned. I’ve got all sorts of big ideas, but just need to figure out how to make them real.
To that end I’ve started to look at the latest releases of operating systems available for the latest Raspberry Pi 2. Before the trip I managed to install the latest Arch, Raspbian, and Windows 10 for IoT. Here’s a quick rundown on what I discovered.
Once the installation process was finished, I put the micro SD card into the RPi 2 and watched it book into a text console. Nothing out of the ordinary in that, and in a way I prefer text over a GUI. My only complaint with the latest Arch is the lack of out-of-the-box WiFi support for the most common WiFi dongles. I had to install WiFi support after my first initial installation of Arch Linux nearly two years ago. Here I am with the latest and I find I’ve got to do that same all over again. My main reason for looking at Arch is its relatively lean footprint, but lack of WiFi support is just a bit too lean. It’s annoying to fix this issue, especially as WiFi networking on the Raspberry Pi is a big feature, two years since the last time is a long time, and when it’s not there out of the box, it’s a big issue.
The latest Raspbian image was installed using my Ubuntu system and the ‘dd’ method for copying the image onto another micro SD card. Once booted, Raspbian will walk you through an initial configuration and expand the file system, consuming the rest of the card. It now boots immediately into a graphical desktop. This is all well and good, but even with a quad-core ARM processor and 1GB of memory, the GUI still taxes the Raspberry Pi 2. This so-called taxing shows as a jitteriness of the mouse cursor as it moves across the screen, among other issues.
I give points to the distribution for fully recognizing my Apple USB keyboard without having to perform any kernel-level configurations, and it recognized both of my WiFi dongles and thus joined the network at boot. For a distribution where you want the greatest assurance it will come up and be usable by an absolute novice to the Raspberry Pi, the current Raspbian distribution can’t be beat. To quote Apple, “It Just Works.”
But I’m still not quite happy with it…
Windows 10 IoT
This was the most sophisticated, and in the end, the most disappointing of the three. I’m glad I gave it a spin, but I would never use it for my own work nor can I recommend it for anyone else to use.
Microsoft has a page to help you get started here. I chose to download an ISO image and to install the tools necessary to flash a micro SD card with the IoT image that comes bundled with that ISO. Once installed on the Raspberry Pi, the Pi booted into Windows 10 with absolutely no problem. The problems came later when it turned out it wouldn’t work with either of the two WiFi USB dongles I’ve been using with Linux ever since the original Raspberry Pi B was purchased.
I spent more time than I cared to slumming through the forums, but no-one seemed to know how to get WiFi working. After about an hour of trying various so-called solutions I shut it down and deleted everything. Yes, I could have plugged the Pi 2 into an open network port on my home router, but I still had no guarantee I would find the proper drivers to make WiFi work. I know how to get all that to work under various Linux distributions. The bigger issue is the requirement to have a desktop Windows system in order to develop for the Raspberry Pi 2. As I’ve written about here you can do some serious and sophisticated work natively on the Raspberry Pi, reaching back to a desktop/laptop only when the development needs are fairly serious. I don’t want to be forced to do this out of the gate. I lived that development life back in the 1990s with Wind River’s VxWorks. While that was fine back then, I don’t want to go back to that, especially now. Even the Beagle Bone Black, which requires a laptop to bootstrap it’s development tools, has everything local to the BBB, and only requires you use a browser.
Unless it changes drastically I’m done with Windows 10 IoT.
There’s a lot that has happened over the last two years, especially with regards to security and encryption. I knew the Internet had devolved into a dangerous place, but I didn’t know how dangerous until the leaks from Edward Snowden and other’s he’s inspired. That has in turn motivated me to think about best practices for securing an internet-of-things device such as the Raspberry Pi 2, and how best to encrypt data both at rest on the device as well as across the wire into and out of the Pi. I’ll have more to write about later, but for the present, I can’t approach this with the same naivete I did in the beginning.
