I just want my OS to work with minimal interaction from me. Right now I’m trying to study and get better at Julia and Python/pandas and that can occupy enough of my time right now. And after that…maybe docker. There’s always plenty to learn. That’s what I want to spend my time studying…NOT OS’s. Not …

Julia PyCall
Successfully used a Python library from Julia! May not sound like a big deal, but have tried unsuccessfully in the past. Suspect problem at my end, possibly install issues between Python 2 and Python 3. But now Python 2 has gone bye bye!
Big Data
I remember when a million customers records was a good size database…not so much today. I talked about Big Data recently. In this article Programming languages: Julia touts its speed edge over Python and R. They mention a benchmark that looks at Apple stock price states – open, high, low and close – using a …
NextCloud laziness
I’ve been very lax in the use/upkeep of my NextCloud server. So finally updated from 18.0.3 to 18.0.7 I really need to play with and explore NextCloud more. The GoodServer mostly turned off and disconnected from the network The Bad and the Ugly…and stupid!Crossed my fingers, rolled the dice…and updated without doing a backup.
Julia on Linux Mint Mate
For some reason the lastest version of Julia 1.4.2 doesn’t work [I get “Illegal instruction (core dumped)] on Linux Mint Mate 19.3. Which is what I’m using at the remote location I’m at during the day. But Julia V1.0.5…does work! I checked the checksums also. And the SQLite changes work also. However the version for …
Julia…Time to first plot
I was watching a YouTube video on Julia by RichardOnData and he talked about the Time to first plot problem. Which I’ve experienced using the SQLite package but never knew it was a Julia thing or heard the term before. Evidently it’s because Julia is a JIT language and compiles modules the first time run …
Julia in Jupyter Notebook
Added the IJulia package in Julia so I can use Julia in Jupyter Notebook! So from julia REPL type:using PkgPkg.add(“IJulia”)
New programming language itch
I have recently been interested in exploring a new programming language…Go and Rust. But now that I again see a future in Julia. I think it will scratch that itch…for a while anyway. I used it enough to be productive with it, but not enough to call myself much more than a beginner. My log …
Julia & VS Code
Found some odd behavior. I usually press F5 (because I’m lazy) to run my programs…and if I made no errors they seem to run fine. However the startup seems slow. Anyhoo because I’ve been working with Jupyter Notebooks a lot lately, out of force of habit I pressed <Shift><Enter> and the program ran very fast. …
More on Julia and SQLite
While I’m excited to get back into Julia, I think I should take it slow with any program using the SQLite package. A quote I always liked kept popping up in my head overnight… Those who cannot remember the past are condemned to repeat it – George Santayana. And if history has shown me anything …
