Mother’s Day, in its best manifestation, is a day to celebrate family and togetherness and children, as well as mothers. On this day though, it’s also good to spare a thought for those who would like to be mothers but can’t be, for whatever reason, and for those who’ve lost their mothers, in whatever way. These celebratory days aren’t unalloyed joy for everyone.

Unthinking Sexism
When I was at university in Auckland, one guy said to me that he hadn’t realized he was sexist until he met me. I’ve always found discrimination based on the biological capability of bearing children to make about as much sense as discrimination based on eye colour. It seems much of the world doesn’t agree, preferring prejudging abilities to the hard work of figuring out real, rather than presumed, capabilities. A lot of discrimination is simply not thinking, accepting the movie or television view of the world and the roles that women and men (or for that matter, people not of western european extraction) have in it.
There’s quite a lot of sexism in technology. One woman I know hates starting a new job, since, as she says, it takes six months to convince the guys I know how to turn on the light
. Shelagh Callahan told me of an experience she had doing booth duty at a conference. She was starting to explain something to this guy when he interrupted her, said she didn’t know enough and he knew Dr Callahan, the leading expert on this topic, and he (Dr Callahan) had a different opinion. At which someone standing next to him suggested he look at Shelagh’s name badge. I’ve had my fair share of condescending males assume I wouldn’t understand what they’re talking about or be able to contribute anything of value to a technical discussion. One could argue that most women wouldn’t understand a technical discussion, but that’s no excuse for the assumption.
Of course, this problem isn’t limited to technology. A female lawyer friend of mine takes some pains to dress differently to the way secretaries dress, for example, so it’s clear she’s a lawyer and not a secretary. She says it’s been interesting watching the development of some men, who at university assumed everyone was a professional and treated them all equally, but once out in the legal workforce started treating men and women differently, assuming women were secretaries and men were lawyers. With the large number of women graduating from law school these days that should change. Whether the practice of pushing women lawyers off into family court (“you’re so good at being understanding”) where they earn less than criminal court lawyers changes soon is an interesting question.
There are lots of aspects to sexism, quite a few where people don’t understand why I find them irritating, or even upsetting. As an example, sending mail addressed to Mr and Mrs {husband’s name}. Having people assume married people share a surname is not unreasonable, but assuming we also share a first name is. To me it smacks of Victorian-era treatment of women, where they were an appendage of the husband, not beings with separate identities. I guess it seems petty to worry about these sorts of things when women in so many countries have it so much worse, but on the other hand sexism creates an environment that is not welcoming. If you don’t feel your presence is valued in a society, then you’re not going to be a full part of that society.
Twins and Genetics
Modern genetics sometimes has a bit of a “believe it or not” feeling to it, things are reported that sound like they come out of Greek mythology. One of the recent news items on the BBC had that feeling for me, where they write about semi-identical twins. These babies, who come from one egg fertilized by two sperm, have the same maternal genetic material and each has some of the paternal genetic material from each sperm. So they’re both chimeras, and one is also a hermaphrodite. Searching through the web for information about society’s treatment of hermaphrodites through the ages is a good way of spending a lot of time reading interesting articles; various cultures and societies have differed greatly in how they treated these people. But I digress.
In mythology chimeras are those beasts that are partly one animal or monster, and partly another. In the modern medical usage of the term, a chimera has two sets of genetic material, so a DNA test taken from one part of the body will give a different result to a DNA test taken from some other part of the body. Some people with eyes of different colours are chimeras, for example, the different colours coming from the differing genetic material.
Another genetically interesting condition that involves twins is the vanishing twin syndrome, where one twin absorbs all the genetic material of the other, sometimes leading to a chimera. The person, if born before early ultrasounds were common, probably won’t even know that he or she started off as one of twins. There was a well-known case of a mother who could only accept a kidney transplant from one of her three sons because the other two had genetic material from the vanished twin rather than the mother who gave birth to them (see the above link or this one for more details).
These things give rise to some interesting issues, such as what about DNA testing? If one person can have the DNA of two people, with one set of DNA in some tissues, and the other set in other tissues, DNA testing becomes problematic. Currently there’s no way of knowing the real proportion of vanished twins, since there is only seldom a reason to test any given person thoroughly enough to find out (one example being needing to prove parentage of children, as in the relatively recent Lydia Fairchild case). Chimeras can have two blood types as well, making them ideal blood recipients, but less than ideal blood donors. That’s another way people may find out, I guess, when they get their blood type tested, but again it’s hard to know what proportion of chimeras have two blood types.
I hope the parents of those babies (now toddlers) succeed in keeping their names and other information private. The interest in their unusual genetic make-up could badly affect their lives if the parents aren’t strong enough to withstand pressure from the press, or scientists, or the curious public. I also hope they’re treated with compassion and empathy as they grow older, rather than intrusive nosiness.
There Are Crazies Out There
I’ve had my share of internet crazies, but nothing like this. Kathy Sierra has had death threats posted on her blog and other blogs. Whatever anyone may think of her (or others’) opinions, threats of this nature are not the answer.
HotMetaL
When I first came to Canada I worked at SoftQuad. SoftQuad was one of the first SGML companies, well known (in some circles, anyway) for its President, Yuri Rubinsky. And well known in many other circles for its HTML editor, HoTMetaL. The Surrey office did most of the development work on HoTMetaL and it was my main focus for quite some time. So it was with a certain amount of nostalgia that I saw HoTMetaL listed on eWeek’s Jim Rapoza Picks the Top Web Technologies of All Time — gone but not forgotten, as they say. Thanks to Kim for sending me the link.
Compostable Plastic
The other day Tim brought home some food in a container that claimed to be made of corn and therefore compostable. I was intrigued by this, since I remember going to street parties and Christmas markets in Germany where the disposable plates were grain-based and even edible (not that people usually did eat them) but haven’t seen them here. So I looked into it a bit more.
The container was made out of something called PLA, which is made from starch. The label said not to microwave it, which had me puzzled — isn’t corn safe to microwave? What would happen? Would it melt? I tried microwaving some water in the container and nothing untoward happened, so I poked around on the website for the company (NatureWorks LLC, a subsidiary of Cargill) to find out more.
The website didn’t give any details that I could find as to why not to microwave the container, so I emailed them. And got back a rather mixed reply. Some breathless marketing prose (new, revolutionary, bridges the gap between natural and synthetic products), the actual answer in the middle, a somewhat odd paragraph about how all the technical info they’re prepared to disclose is on the website (if the answer to the microwave question had been there, I wouldn’t have emailed them). Anyway, the answer is supposedly that PLA has a low melting point, so the containers might leak in the microwave.
Next Step
So if this container is compostable, where can one compost it? The store has a big bin to take them back, but what about the Vancouver compost facility? Or indeed my compost bin? The cashier said “oh, just throw it in your compost bin.” “Are you sure?” “Yes, absolutely”. According to the PLA brochure, you need 140ºF and humidity between 80% and 90% for extended periods of time
. So that rules out my compost bin. And the Vancouver City compost facility as well, unfortunately, since they use an open windrow process. I emailed the relevant people in the Vancouver City engineering department, and they pointed out not only would it not compost, if I put the plastic in the yard waste bin, it might encourage other people to put unsuitable plastic containers in there. So it’s back to the store with the containers; fortunately it’s not a big deal since it’s one of the local stores we shop at anyway.
