The Obstetrical dilemma.

I've been watching the BBC program 'Horizon - What Makes us Human' and there's an interesting segment on the obstetrical dilemma. The dilemma is 'Why is human childbirth so hard when compares to other primates?' The conventional answer is that there are two conflicting requirements: larger brain are an advantage hips that are too wide are a disadvantage So women's hips cannot evolve to be really wide to make childbirth easy because that disadvantages the mothers too much compared to the advantages of a large brain. The program shows some research that demonstrates that wide hips don't make walking & running harder for a woman and so there's no walking/running related disadvantage to wide hips. The program goes onto show that as the fetus grows it demands more and more energy from the mother via the placenta. There's a limit to just how much energy the mother can deliver to the fetus via the placenta. It turns out that at 9 mont...

What about Khat?

Reading this weeks New Scientist I see that "Mephedrone is a synthetic analogue of the herbal amphetamine cathinone, found naturally in the leaves of the khat plant, Catha edulis ." Does that mean that khat will also be banned? Personally, I still think that drugs should be legalised, taxed and available to all adults in possession of a state issued 'junkie card'. The war on drugs was lost a long time ago and instead of making drugs barons rich we should raise some tax revenue. From time to time I ask people who claim to to take drugs if, following legalisation, they would take drugs. I've yet to have someone say yes. Do we really think there would be a tide of new drugs takers following legalisation? It's worth looking at what's happened in Portugal where personal possession has been de-criminalised. Deaths and rates of HIV infection are down. " Street drug overdoses dropped from around 400 to 290 annually" so that's 110 people saved du...

Stuck between an Android and a Hard Base Station

[ It seems that whatever was broken in the S6 1Nov 2017 security baseline update was fixed in the 1 Jan 2018 security baseline update.] Our Mesh WiFi is still great and working really well now. I'm using NETGEAR ProSAFE GS108 switches to provide the Ethernet backhaul for all the WiFi disks. It's a simple gigabit Ethernet switch and works a treat. However, I now have a problem device, my Samsung Galaxy S6. Following a recent Android security update from the August 2017 to November 2017 baseline ( in mid December) the S6 keeps disconnecting from the Mesh WiFi. After some Googling around it seems that the problem is the the security update does not like seeing the same WiFi SSID on both the 2.4Ghz and 5Ghz WiFi networks. The main symptom is that the S6 WiFi keeps disconnecting. First, I connect to the WiFi and all is well and importantly I've just entered the correct password. Then shortly afterwards I find the S6 has disconnected from the WiFi and the error message ...
