A Good Time to Upgrade PCs

PC hardware just keeps getting cheaper and faster. Now that so many people have been working from home the deficiencies of home PCs are becoming apparent. I’ll give Australian prices and URLs in this post, but I think that similar prices will be available everywhere that people read my blog.

From MSY (parts list PDF […]

IT Asset Management

In my last full-time position I managed the asset tracking database for my employer. It was one of those things that “someone” needed to do, and it seemed that only way that “someone” wouldn’t equate to “no-one” was for me to do it – which was ok. We used Snipe IT [1] to track the […]

About Reopening Businesses

Currently there is political debate about when businesses should be reopened after the Covid19 quarantine.

Small Businesses

One argument for reopening things is for the benefit of small businesses. The first thing to note is that the protests in the US say “I need a haircut” not “I need to cut people’s hair”. Small businesses […]

Rolling Stone has an insightful article about why the Christian Right supports Trump and won’t stop supporting him no matter what he does [1].

Interesting article about Data Oriented Architecture [2].

Quarantine Will normalise WFH and Recession will Denormalise Jobs [3]. I guess we can always hope that after a disaster we can learn to […]

Coronavirus and Work

Currently the big news issue is all about how to respond to Coronavirus. The summary of the medical situation is that it’s going to spread exponentially (as diseases do) and that it has a period of up to 6 days of someone being infectious without having symptoms. So you can get a lot of infected […]

Amazon Prime and Netflix

I’ve been trying both Amazon Prime and Netflix. I signed up for the month free of Amazon Prime to watch “Good Omens” and “Picard”. “Good Omens” is definitely worth the effort of setting up the month free of Amazon Prime and is worth the month’s subscription if you have used your free month in the […]

Truthout has an interesting summary of the US “Wars Without Victory and Weapons Without End” [1]. The Korean war seems mostly a win for the US though.

The Golden Age of White Collar Crime is an informative article about the epidemic of rich criminals in the US that are protected at the highest levels [2]. […]

DisplayPort and 4K

The Problem

Video playback looks better with a higher scan rate. A lot of content that was designed for TV (EG almost all historical documentaries) is going to be 25Hz interlaced (UK and Australia) or 30Hz interlaced (US). If you view that on a low refresh rate progressive scan display (EG a modern display at […]

Self Assessment

Background Knowledge

The Dunning Kruger Effect [1] is something everyone should read about. It’s the effect where people who are bad at something rate themselves higher than they deserve because their inability to notice their own mistakes prevents improvement, while people who are good at something rate themselves lower than they deserve because noticing all […]

Deleted Mapped Files

On a Linux system if you upgrade a shared object that is in use any programs that have it mapped will list it as “(deleted)” in the /proc/PID/maps file for the process in question. When you have a system tracking the stable branch of a distribution it’s expected that most times a shared object is […]
