but I recently started thinking about trying out some lightweight data projects on it. I know it’s not a powerhouse machine, but it’s fun to see what it can handle.
Right now, I’m facing a bit of a wall trying to run a small Python script that pulls CSV data and processes it. The script runs fine on my main PC, but it crashes midway on DevTerm. No clear error, just hangs. Anyone else run into similar issues with basic data tasks?
Also, I’m learning about different data tools and came across something called Power BI dashboard. I know it’s Microsoft-based, but I’m curious..what is Power BI dashboard exactly, and can something similar be built with open-source tools that might run on DevTerm?
Would love to hear if anyone has used DevTerm for data logging or dashboard-style projects. Thanks in advance for any tips or insights!
Not using my DevTerm for data tasks, but it can handle SDRangel with a LimeSDR MIni just fine for decoding various signals.
Without doing some basic instrumentation we can’t help much in that regard.
As a start I’d try to open up htop and monitor CPU and memory usage.
Another thing worth trying is the hanging_threads package to rule out any deadlocks with processing the CSV.
As for dashboards, I once tried tview for the terminal.
Maybe using gopy you can directly interface with that if you like terminal graphics.
Apart from that, I’d love to know more about data dashboards running on a DevTerm.
I know there’s grafana, but I also once dabbled with NASA’s openmct for telemetry.
If you have the R-01 CPU the DevTerm is astounding slow. But unless you’re churning through megabytes of data in a hurry you can probably do what you want with the DevTerm.
I haven’t done much with Python and CSV simply because its a pain and I have other tools for dealing with CSV, like “Pi Shack BASIC”. I often use it in conjunction with AWK, since AWK can provide really useful summary functions with an extreme economy of code.
If you haven’t given up entirely I’d like to take a gander at your code and maybe a sample data file. I could run it on my DevTerm and see if and where it hangs, possibly providing some insight.
Unfortunately I have not seen any decent DB tools in Linux since Open Office gutted the DB layer from Star Office. Even then the Star Office layer was clumsy at best. Things like Fox Pro, PFS Window Works, Access, … simply don’t exist. Most all Linux DB has moved into the SQL + web site realm. But if you don’t mind writing some code any computer will do DB work.
