The atheist delusion | Review | guardian.co.uk Books An atmosphere of moral panic surrounds religion. Viewed not so long ago as a relic of superstition whose role in society was steadily declining, it is now demonised as the cause of many of the world's worst evils. As a result, there has been a sudden explosion in the literature of proselytising atheism. A few years ago, it was difficult to persuade commercial publishers even to think of bringing out books on religion. Today, tracts against religion can be enormous money-spinners, with Richard Dawkins's The God Delusion and Christopher Hitchens's God Is Not Great selling in the hundreds of thousands. The abrupt shift in the perception of religion is only partly explained by terrorism. For Dawkins and Hitchens, Daniel Dennett and Martin Amis, Michel Onfray, Philip Pullman and others, religion in general is a poison that has fuelled violence and oppression throughout history, right up to the present day. As in the past, this is a type of atheism that mirrors the faith it rejects.
Computer virus Computer viruses currently cause billions of dollars worth of economic damage each year,[14] due to causing systems failure, wasting computer resources, corrupting data, increasing maintenance costs, etc. In response, free, open-source antivirus tools have been developed, and a multi-billion dollar industry of antivirus software vendors has cropped up, selling virus protection to users of various operating systems of which Windows is often the most victimized, partially due to its extreme popularity.[citation needed] No currently existing antivirus software is able to catch all computer viruses (especially new ones); computer security researchers are actively searching for new ways to enable antivirus solutions to more effectively detect emerging viruses, before they have already become widely distributed.[15] Vulnerabilities and infection vectors[edit] Software bugs[edit] Social engineering and poor security practices[edit] Vulnerability of different operating systems to viruses[edit]
Worry doll An assortment of worry dolls. Worry dolls (muñecas quitapenas), or trouble dolls, are very small and colorful dolls traditionally made in Guatemala.[1] A person (usually a child) who cannot sleep due to worrying can express their worries to a doll and place it under their pillow before going to sleep. Some medical centers use them in conjunction with treatment for disease in children.[2][3] According to folklore, the doll is thought to worry in the person's place, thereby permitting the person to sleep peacefully. The person will wake up without their worries, which have been taken away by the dolls during the night. Parents may remove the doll during the night, reinforcing the child's belief that the worry is gone. Some parents involve the child in making the dolls to further increase the psychological benefits of releasing worries, and instructions may be found online. Because they are inexpensive and small to transport, many tourists buy the dolls.[4] References[edit]
Easy Backup and Restore - Linux Introduction Until recently the extent of my backup efforts were to take the occasional CD copy of my home directory and keep copies of important files somewhere else, usually on another disk partition, or a floppy disk. All this changed with the need to run some Windows legacy applications. The only machine really suitable for this work was my main workstation, a 1.2 GHz Athlon machine, multiboot with four distributions. I freed up the 1st primary partition by transferring the contents of that to the 7th partition, overwriting an expendable Vector Linux 3.0 Distribution. At this point one would normally just DOS format the now free first partition and install Windows. The machine was now running Mandrake 9.0, Debian 3.0 and Slackware 8.1. At that point the desire to have a simple, easy and foolproof backup and recovery method took hold. What do we really need for a backup and recovery system? If we are a home or SOHO Linux user I would suggest the following, it should: What can we use #! #!
Evil Bible Home Page Microcap stock fraud The "night singer of shares" sold stock on the streets during the South Sea Bubble. Amsterdam, 1720. Microcap stock fraud is a form of securities fraud involving stocks of "microcap" companies, generally defined in the United States as those with a market capitalization of under $250 million. Its prevalence has been estimated to run into the billions of dollars a year.[1][2][3] Many microcap stocks are penny stocks, which the SEC defines as a security that trades at less than $5 per share, is not listed on a national exchange, and fails to meet other specific criteria.[4] Microcap stock fraud generally takes place among stocks traded on the OTC Bulletin Board and the Pink Sheets Electronic Quotation Service, stocks which usually do not meet the requirements to be listed on the stock exchanges. Microcap fraud encompasses several types of investor fraud: Pump and dump[edit] Many penny stocks, particularly those that trade for fractions of a cent, are thinly traded. Chop stocks[edit]
What Congress Would Look Like If It Were Demographically Representative of America More Infographics on Good Network Time Protocol - NTP Purpose - to discuss what NTP is, and to discuss coding issues relating to this protocol.DAYTIME port 13 RFC 867 [1]TIME port 37 RFC 868 [2]NTP port 123 RFC 1035 [3]SNTP port 123 RFC 2030 [4]The DAYTIME and TIME protocols are simple responders. When a connection is made or a packet recieved the server simply responds with the current time as an ASCII string for DAYTIME or as a binary value for TIME.SNTP is a reduced version of the NTP protocol that can be used to replace TIME clients.NTP is a far more sophisticated protocol created by Dave Mills. Version 3 of NTP is described in RFC1305 [5]. More information including links to Dave Mills' ntpd implementation is available at Documentation and other links are at NTP is implemented via UDP over port 123, and can operate in broadcast and multicast modes, or by direct queries. tcllib includes an implementation of a client for SNTP and TIME. exec cmd.exe ... ].
