Articles from drwxr-xr-x.org transferred to dleigh.net
All of the articles from my 2019-2021 blog Readable by all (drwxr-xr-x.org) have been moved to this site, with one exception - the very first “About” post which was about how the new blog format should help me post more frequently, which obviously didn’t happen.
Returning Home(page)
So, no updates for over two years.
I’ve been very unwell to the point I need assistance to do even basic household tasks like cleaning and preparing meals. Unfortunately I’ve already used the title “Rumours of my death have been slightly exaggerated” back in 2018, and it wasn’t even the last post I had to make on this topic.
While most of my life is a complete mess, I do have a few ideas about being able to actually get some more stuff I’ve done posted online.
Disability and Rarity of Updates
Haven’t made any updates to this site or my “new” blog in over a year until I cleaned up and posted this biology article a few days ago. Even before then, I hadn’t made a post talking about my disabilities and past and how badly it affects my ability to get things done.
This post (originally on the new blog) will explain some of those issues, what I’ve been up to since last year, and what I might be able to do in the future.
Forms of Life part 2: Overview of the Phylogenetic Tree of Life and Endosymbiosis
In the first part of this series, I discussed taxonomic terminology such as clades and kingdoms, but didn’t go into the actual groups and the lifeforms within them. This article will provide a top-down phylogenetic overview of all lifeforms on Earth, as well as a discussion of how endosymbiosis has provided an alternate path for genetic material and evolution.

The Delightful Diversity of “Cup” Sizes in UK/US/AU/NZ Cooking
Volumetric measurements (using the volume of a container) are inferior to Gravimetric measurements (i.e. weight) in most ways. Weighing is faster (for a given pareto-optimal degree of accuracy), can achieve greater accuracy, and most importantly there will be less dishes to clean up afterwards.
Most irritatingly, “cups” and “spoons” mean different amounts in different countries. Even worse, sometimes three “thirds” of a cup are less than one cup…
[Updated 2020-03-22: Added cup densities for wheat bran and oat bran]
10 Minute “Meaty” Vegan Moroccan Pilaf
10 minutes cooking time, that is, so to be honest it’s about 12-15 minutes total.
- This is my usual standby meal because it meats (heh) all my requirements:
High in fibre (wholegrain burgul and veg)
High in protein (soya mince and wholegrains)
Relatively low in calories
Filling meaty taste, but no animal products
Each serve contains two 75g Australian “serves” of vegetables
Only uses non-perishable ingredients, so no need to plan ahead
Faster to make from scratch than to get takeaway
Only uses one pan/pot

More Evidence Early Human Diets Were Highly Plant/Carb Based
An article in last month’s Science, “Cooked starchy rhizomes in Africa 170 thousand years ago”, provides some archaeological evidence of early humans cooking and eating tuber-like vegetables.
