IBM PC Jr. Language Reference

Well, it’s more generic than that, but I needed it to recall how to do some display stuff on the PC Jr.

I set the Jr. up because I was talking with some future coworkers, and they had a history, or familiarity, with the PC Jr, so I figured it’d be a funny introduction to throw a big letter greeting up on the screen.

I started to think about how to create a ‘real’ program to generate banners based on input, but I realized perhaps I should be focusing on forward looking items, not stuff from 40 years ago! So the Jr. is back on the display shelf, and I’m moving onto AWS stuff.

Great writeup: Specificity: Your Brain’s Superpower

Not mine, but very good. While some of this can come off negatively (think about how you say things!), the overall thought process is great. Frequently I use some of these techniques and they are very effective!

Results of a Password Cracking Contest

Just hanging onto this for future reference. Not for the passwords obviously, but the process that the ‘best password cracker’ student used – pretty effective.

Relational vs. NoSQL Databases

This article provides a nice, brief, overview of the differences between relational and NoSQL databases.

So far in all the systems I’ve developed, we’ve stuck with relational databases for the primary data stores, and then used others, such as ElasticSearch, and key-value based caches, for areas where traditional SQL couldn’t keep up (or didn’t need to be hit 50,000 times per minute for something that rarely changes). It definitely takes some effort, but mixing and matching to meet your needs works out better than being religious about a given data storage and access methodology and technology!

Want MS services to use your primary account?

Many of us log into multiple MS or AAD accounts, and when visiting MS sites, it will present a list of logged in accounts to pick from. However, for many of us, those other accounts are only for things like email, so it is an extra step we really don’t need.

This Edge plug in solves the problem. You can toggle it on and off very easily for those times when you do want to be prompted.

37% of COVID-19 Patients Diagnosed With A Long-COVID Symptom

A lot of people look at Covid-19 as having two possible results when you get it – you’re either perfectly fine, or dead. Reality is much more complicated. I know several people who have died from it, several who have had no symptoms, and several who are dealing with long term complications from it.

I’m just tossing this up here to keep track of it.

YouTube video – the video game collecting bubble

It takes quite a bit to hold my attention for 50 minutes, especially on YouTube, but this video did it. I’ve watched from the sidelines as the prices of all antique computer collectables have gone through the roof, and I’ve been shocked at the crazy pricing of video games in particular. The video linked above does a great job of exposing the fraud and deception in the retro video game market (oddly, that’s the title of the video!).
