Writing more Julia programs…specifically file I/O I had read about it before, but string concatenation got me a few times today, must use ‘*’ and NOT ‘+’

Julia
I think I’m going to like Julia it’s VERY much like Python.
Julia
Discovered and installed the programming language Julia. It’s been around for a few years but just attained version 1.0 status less than a month ago. Also wrote my 1st simple program to get a feel for the language.
Docker
Created my 1st docker container running a small python program I wrote called slice.py. The dockerfile…contained… FROM python:2.7 RUN mkdir /root/pythonlib/ COPY slice.py /root/pythonlib/myapp.py CMD [“python”, “/root/pythonlib/myapp.py”] The container is created from the above by… docker build -t bill-py . It is the run like so… docker run bill-py
More Julia/VS Code
Really enjoying Julia. Although geared towards scientific, data science and numerical computing, it’s also, I’ve read, a great general purpose language. I’m not a data scientist so my intent lies more in line with general programming. Doing things I might have used Python for. Thing’s I like! Very Python like!!! Integrates very well with a …
Docker
Installed docker using most recent Youtube Video for Ubuntu 16.4, on which Linux Mint 18.3 is based. Had some problems because of differences between Ubuntu & Linux Mint.
Python greenbar program
Python greenbar program coming along…PDF [1st page blank]. This is probably as much work as I’m going to put into this. I started out just to see if I could.
IBM greenbar/bluebar computer printout
Start work on Python program to create old IBM green or blue bar computer printout listings…for that vintage look. Was inspired from a MS-Windows only program [HercPrt] that uses sockets to print computer listings to PDF. Mine is different and not as sophisticated. It formats regular text files to PDF after output. I did this …
MVS
Continuing retro. MVS. An OS more advanced than the one…OS/360 [MVT] I used at school. I had no interactive editor, I had to punch cards and submit to a card reader! Then wait an hour or more for the computer operator to print out my listing…after it’s turn in the job queue. Then if any …
DOS/VS operator console
Continuing retro. Here’s a DOS/VS operator console which looks very much like the VSE systems I worked on for years. I had some trouble finding the DOS/VS 5 pack. But thanks to “computeroperator” on YouTube…he was able to help me find it! My desktop is obscured by the editor. but you can see it’s taskbar …
