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.

We’ve had prob­lems with get­ting the baby (now 10 months) to sleep prop­erly dur­ing the day, and when she also star­ted wak­ing more often dur­ing the night I decided I had to fig­ure out an answer. Our first child slept read­ily, took sched­ule vari­ations in his stride, and so it was a big shock when our second child was com­pletely dif­fer­ent. We tried put­ting her on vari­ous routines, but could­n’t find one that worked until recently (yay! sleep!). Giv­en that lots of searches on my blog are about how to get babies to sleep, and the vast num­ber of books out there on the sub­ject, I fig­ure some oth­er people might be inter­ested in the sub­ject. The rest of you will undoubtedly have already tuned out by now.

I got heaps of books out of the lib­rary, but can only recom­mend two. Some of the books seemed to be writ­ten along the lines of “this worked for me, I don’t know why, maybe it will work for you too” and per­son­ally I prefer an approach that has a little more research to it. I’m not going to talk about the books I read and did­n’t like since oth­er people may find them use­ful; I’m just going to review the two books I liked best.

If your baby is young, you could try The Hap­pi­est Baby on the Block: The New Way to Calm Cry­ing and Help Your Baby Sleep Longer, which looked like it had some use­ful tips. I would­n’t both­er with it if your baby is more than about 6 months old though.

The book I liked a lot, and even bought, is Healthy Sleep Habits, Happy Child, which con­tains a lot of inform­a­tion, includ­ing some research into how long chil­dren sleep at vari­ous ages, a strict routine (which really suits our baby but would­n’t have been neces­sary for our first child), and dis­cus­sions about what to do as the child gets older in terms of chan­ging the sleep and nap routine. A lot of people may find the advice to let the baby cry harsh — you do have to be able to recog­nise the vari­ous types of cry your baby makes so you can respond to fear or dis­com­fort while ignor­ing the baby when she’s annoyed. It worked very well for us (at least so far and we’ve been on the sched­ule for a week) and we not only have our happy baby back, I’m also catch­ing up on sleep. Get­ting up at 6:30 am every morn­ing is a bit of a change, but not being woken up at 11 pm, 2 am, and 5 am more than makes up for it.

Yes­ter­day the latest release (4.0) of Debi­an came out. I decided to be big and brave and upgrade imme­di­ately; I’ve nev­er had any prob­lems with upgrad­ing Debi­an before and did­n’t expect to now. It took forever to down­load, ages to install (with me keep­ing all the old con­fig files as I always do). And then, at the end, our inter­net con­nec­tion was dead. Our inter­net con­nec­tion is via PPP, which was tricky to set up, so it seemed best to tackle the prob­lem in the morn­ing rather than risk mak­ing things worse.

This morn­ing I found that the ppp script in the /etc/init.d dir­ect­ory was­n’t there, but a #ppp# script was, with the right con­tent. So I renamed the file back to ppp, checked the backups to put the right sym­links into the vari­ous /etc/rx.d dir­ect­or­ies, and rebooted. Voila! An inter­net con­nec­tion. Now I just have to fig­ure out why apache2 isn’t run­ning. [Update: because it was upgraded to ver­sion 2.2 and the authen­tic­a­tion con­fig file syn­tax was changed, that’s why.]

I have no idea wheth­er the PPP prob­lem came from the dis­tri­bu­tion, or some­thing odd in my con­fig­ur­a­tion (although I’ve done full dist-upgrades before with no prob­lems). I did a hunt on the Debi­an wiki and found that Debi­an has added more PPPoE sup­port recently, so maybe there was a clash in there some­how. I’m glad I was para­noid enough to make backups of the /etc dir­ect­ory to com­pare with. At some stage I guess I should fig­ure out wheth­er to replace the cur­rent con­fig­ur­a­tion with the new Debi­an sys­tem, although I don’t like muck­ing about too much with things that actu­ally work, espe­cially when it comes to some­thing as vital as being able to con­nect to the Net.

I’ve star­ted using the Bad Behavior/Bad Beha­viour plu­gin for Word­Press, which is meant to cut down on the num­ber of spam­bots that attempt to access my site. In the­ory it should­n’t block any real vis­it­ors, although this has been known to hap­pen, so if you notice any prob­lems (e.g., can­’t get to my blog from a feed, or from a link or search), please let me know. The plu­gin has been installed a week and nobody’s repor­ted any prob­lems so far. It works nicely with Spam Karma, the spam block­er I use.

I can recom­mend this plu­gin based on my exper­i­ence so far; I’ve noticed the amount of spam that I get is much less, which means that I will be able to check the Spam Karma logs for any real com­ments that were inad­vert­ently caught. If you’re plagued by spam bots on your blog and you have some con­trol over the envir­on­ment, it might be worth try­ing out.

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.
