Welcome to decuser's blog
Topics on this blog include computing, retro-computing, operating systems, math, and whatever other technical subjects I happen to be exploring that I find interesting enough to take and share notes about.

Warren Toomey Awarded 2022 USENIX Flame
Warren Toomey, the founder and maintainer of all things related to The Unix Heritage Society (TUHS) https://www.tuhs.org/ has been awarded the 2022 USENIX Lifetime Achievment Award ("The Flame").
Without TUHS, it would hardly even be possible to enjoy retro unix explorations. This is a well earned accolade by an unassuming and very hard working individual.
Congratulations, Warren!

unix python
dircmp.py - a plan to improve and extend
dircmp.py
A plan to improve and extend
This note pertains to dircmp.py a program that I wrote to give me information about two directories for the purpose of deciding what to keep and what to remove and to learn about python. The note is a draft note and as such it's not very refined and it may lack in many ways, but I thought it might be interesting to put it out there and let anyone see it. Email me if you have comments or suggestions.

Site Update for Thursday, December 8, 2022
The Blog is completely migrated! It's good to be over that google blog experience. Too little control. It's like I stopped having to take lyft and got my own car with a free parking pass.
We are live! Of course, if you see any issues, just shoot me an email. Yeeha!
Oh, and I added search :).

Site Update for December 3, 2022
Added pagination. Whew, took a bit of work, but seems more manageable on the whole. I'll add a post about it :).

Site Update for December 2, 2022
Everything up through June 29, 2022 is live. If you see any problems, shoot me an email. In the meantime, I'm working on getting the rest of 2022 posted and then I will take care of the explorations tabs. I also have some ideas for new content that I would like to get posted before I take a break.

Under Construction Notice
This blog is currently under construction. As part of the migration discussed in [Welcome Post (Nov 29, 2022)]({% post_url 2022-11-29-welcome-to-jekyll %}), I am moving content from various places into the blog. The Exploration links will eventually refer to content that I bring in or add, but for now they just link to this notice. I am working from oldest to newest and just finished 2002-2015. I'll be moving the rest little by little to backfill. Please be patient!

Welcome to Decuser's Blog on GitHub
This Blog ranges over diverse technical topics such as Retrocomputing, Unix, and Programming
Over the coming weeks, I will be moving my blog posts over from blogspot to here. My reason for moving is apolitcal and is simply because I wanted more control over my content. With GitHub Pages, my content is my own and it is simple to create new posts. With blogspot, it was difficult to do backups and creating content was a pain as well. Here's hoping the transition will be relatively painless :).

unix research-unix v7
Installing and Using Research Unix Version 7 in the OpenSIMH PDP-11/45 and 11/70 Emulators 3.1
This note covers building a working v7 instance from tape files that will run in the OpenSImH emulator. First, the reader is led through the restoration of a pristine v7 instance from tape to disk. Next, the reader is led through adding a regular user and making the system multi-user capable. Then, the reader is shown how to make the system multi-session cable to allow multiple simultaneous sessions. Finally, the system is put to use with hello world, DMR style, and the learn system is enabled.
The note explains each step of the process in detail.
