Hide a User from the Windows XP Welcome Screen

This will prevent the user from showing up on the welcome screen. You will need to press CTRL-ALT-DEL twice at the logon screen to get the old W2K logon style box to be able to logon to the account you’ve hidden. Adding a username and setting the value to 1 will cause that user, such as Administrator, to show up on the Welcome screen as well.

Illusions

I love optical illusions. They remind me of the limitations of our sensory engagement with the world and just how much our brains really contribute to processing those inputs. Our brains do ‘fill in the blanks a lot’, exemplified by this paragraph that was prolific on the web in the early 2000s: Aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn’t mttaer in waht oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht the frist and lsat ltteer be at the rghit pclae. The rset can be a toatl mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe. Net result: reality is in the mind. Animals remind us of those sensory constraints. The commoner garden blackbird has far greater colour-vision/acuity than humans. From its perspective, other blackbirds are a multitude of colours. Perhaps the octopus illustrates the sentiment better though as Peter Godfrey-Smith discusses in Other Minds: The Octopus, The Sea, and the Deep Origins of Consciousness – the octopus is an intelligent creature whose evolutionary path diverged from our own 750 million years ago and its[…]

Headless Human Clones

My forum post on MedWeb (Birmingham University) It seems to me, that discussions of medical ethics with peers, in journals and the media tend to focus on ethical implications of only current medical abilities, despite however long they have been in exercise. An example would be abortion which was practised in Greek and Roman times. The first recorded recipe for an abortion producing drug was in 2600BC. Thomas Aquinas considered the scientific and theological aspects of abortion in depth in the 13th century. Other examples include organ transplantation and euthanasia. Medicine, is one of the most, rapidly changing disciplines in society. Constantly new techniques, evidence and trials are being developed. I wonder whether or not we should be considering ethical issues concerning medical practice where the possibility of that medical practice will not emerge until a few decades. Cloning and the benefits to humans are becoming more obvious. Scientists have already a headless frog embryo. It does not seem a distant possibility of headless human clones. In fact, it is real possibility that in a few decades we could have the ability to grow clones of ourselves from birth. These clones would be engineered to be biographically dead (a persistent[…]
