Somebody said to me once. “I don’t talk about religion or politics. Why? Everyone has their own opinion and I’ll just pull the other into a negative emotional state if we talk about those topics. Thus I have to stay on other subjects, so they associate positive emotions with me.”
Nothing new. However I have to add the topics of :
For this project the customer wanted TeamViewer running on a Raspberry Pi Nano so that a programmer he hired from interstate could connect easily to get some scripts running. For the more tech savvy an SSH terminal connection is by far more solid and runs easily on a Pi Nano, but the configuration is harder as a port forward would have to be setup on the customers home or business router and then DNS resolution has to happen. In the end that set up would be more fault tolerant, but then again it depends on how you look at it.
TeamViewer has almost become an industry standard as it is generally fast, reliable and easy to set up. I’ve not done a speed test between TeamViewer and FreeNX, but for ease of use TeamViewer is great. It also bypasses the firewall using tunneling without compromising security.
Back to the job at hand. It turns out that the older older ARM chips found in the Nano and the Pi 1 do not support SIMD (Single Instruction Multiple Data). SIMD is a type of parallel computing involving vectors (beyond the scope of this article). Either way the ARM processors in the Pi3 have an architecture called NEON which supports SIMD.
After 4ish hours of flattening the OS, reinstalling Raspbian, hunting for the appropriate version of TeamViewer host for Linux and then figuring out what the spurious errors meant I finally realised the NEON SIMD issue above. I popped the SD card out of the Raspberry Pi Nano and put it in a Pi3 B+ and away it went. Mission accomplished.
I was in a small town outside of Zurich a few years ago for NYE. Her house is slightly higher than her town and you could face any direction from there and the horizon was a sea of fireworks. At my cousins unit in the middle of Vienna he took a video 360 degrees and it’s the same. It’s just everyones personal fireworks everywhere. Brazil is the same as this video shows from a plane.
