In the x86 architecture, the CPUID instruction (identified by a CPUID opcode) is a processor supplementary instruction (its name derived from CPU IDentification) allowing software to discover details of the processor. It was introduced by Intel in 1993 with the launch of the Pentium and SL-enhanced 486 processors.

A program can use the CPUID to determine processor type and whether features such as MMX/SSE are implemented.

Coley's toxins (also called Coley's toxin, Coley's vaccine, Coley vaccine, Coley's fluid or mixed bacterial vaccine) is a mixture consisting of killed bacteria of species Streptococcus pyogenes and Serratia marcescens, named after William Coley, a surgical oncologist at the Hospital for Special Surgery who developed the mixture in the late 19th century as a treatment for cancer.

There is no evidence that Coley's toxins have any effectiveness in treating cancer, and use of them risks causing serious harm.

Biophilic design is a concept used within the building industry to increase occupant connectivity to the natural environment through the use of direct nature, indirect nature, and space and place conditions. Used at both the building and city-scale, it is argued that this idea has health, environmental, and economic benefits for building occupants and urban environments, with few drawbacks. Although its name was coined in recent history, indicators of biophilic design have been seen in architecture from as far back as the Hanging Gardens of Babylon.

Everybody Draw Mohammed Day (or Draw Mohammed Day) was a 2010 event in support of artists threatened with violence for drawing representations of the Islamic prophet Muhammad. It stemmed from a protest against censorship of the American television show South Park episode "201", led by the show's distributor Comedy Central, in response to death threats that had been made against some of those responsible for two segments broadcast in April 2010. A drawing representing Mohammed was posted on the Internet on April 20, 2010, with a message suggesting that "everybody" create a drawing depicting Mohammad on May 20 in support of free speech.

U.S. cartoonist Molly Norris of Seattle, Washington created the artwork in reaction to Internet death threats that had been made against animators Trey Parker and Matt Stone for depicting Muhammad in an episode of South Park. Postings on RevolutionMuslim.com (under the pen name Abu Talha al-Amrikee; later identified as Zachary Adam Chesser) had said that Parker and Stone could wind up like Theo van Gogh, a Dutch filmmaker who was stabbed and shot to death.

Norris claimed that, if people draw pictures of Muhammad, radical Islamist terrorists would not be able to murder them all, and threats to do so would become unrealistic. Within a week, Norris' idea became popular on Facebook, was supported by numerous bloggers, and generated coverage on the blog websites of major U.S. newspapers. As the publicity mounted, Norris and the man who created the first Facebook page promoting the May 20 event disassociated themselves from it. Nonetheless, planning for the protest continued with others "taking up the cause". Facebook had an "Everybody Draw Mohammed Day" page, which grew to over 100,000 participants (101,870 members by May 20). A protest page on Facebook against the initiative named "Against ‘Everybody Draw Mohammed Day'" attracted slightly more supporters (106,000 by May 20). Subsequently, Facebook was temporarily blocked by Pakistan; the ban was lifted after Facebook agreed to block the page for users in India and Pakistan.

In the media, Everybody Draw Mohammed Day attracted support from commentators who felt that the campaign represented important issues of freedom of speech, and the need to stand up for this freedom.

🔗 Cryptography 🔗 Cryptography/Computer science

In cryptography, nothing-up-my-sleeve numbers are any numbers which, by their construction, are above suspicion of hidden properties. They are used in creating cryptographic functions such as hashes and ciphers. These algorithms often need randomized constants for mixing or initialization purposes. The cryptographer may wish to pick these values in a way that demonstrates the constants were not selected for a nefarious purpose, for example, to create a backdoor to the algorithm. These fears can be allayed by using numbers created in a way that leaves little room for adjustment. An example would be the use of initial digits from the number π as the constants. Using digits of π millions of places after the decimal point would not be considered trustworthy because the algorithm designer might have selected that starting point because it created a secret weakness the designer could later exploit—though even with natural-seeming selections, enough entropy exists in the possible choices that the utility of these numbers has been questioned.

Digits in the positional representations of real numbers such as π, e, and irrational roots are believed to appear with equal frequency (see normal number). Such numbers can be viewed as the opposite extreme of Chaitin–Kolmogorov random numbers in that they appear random but have very low information entropy. Their use is motivated by early controversy over the U.S. Government's 1975 Data Encryption Standard, which came under criticism because no explanation was supplied for the constants used in its S-box (though they were later found to have been carefully selected to protect against the then-classified technique of differential cryptanalysis). Thus a need was felt for a more transparent way to generate constants used in cryptography.

"Nothing up my sleeve" is a phrase associated with magicians, who sometimes preface a magic trick by holding open their sleeves to show they have no objects hidden inside.

The effects of stress on memory include interference with a person's capacity to encode memory and the ability to retrieve information. Stimuli, like stress, improved memory when it was related to learning the subject. During times of stress, the body reacts by secreting stress hormones into the bloodstream. Stress can cause acute and chronic changes in certain brain areas which can cause long-term damage. Over-secretion of stress hormones most frequently impairs long-term delayed recall memory, but can enhance short-term, immediate recall memory. This enhancement is particularly relative in emotional memory. In particular, the hippocampus, prefrontal cortex and the amygdala are affected. One class of stress hormone responsible for negatively affecting long-term, delayed recall memory is the glucocorticoids (GCs), the most notable of which is cortisol. Glucocorticoids facilitate and impair the actions of stress in the brain memory process. Cortisol is a known biomarker for stress. Under normal circumstances, the hippocampus regulates the production of cortisol through negative feedback because it has many receptors that are sensitive to these stress hormones. However, an excess of cortisol can impair the ability of the hippocampus to both encode and recall memories. These stress hormones are also hindering the hippocampus from receiving enough energy by diverting glucose levels to surrounding muscles.

Stress affects many memory functions and cognitive functioning of the brain. There are different levels of stress and the high levels can be intrinsic or extrinsic. Intrinsic stress level is triggered by a cognitive challenge whereas extrinsic can be triggered by a condition not related to a cognitive task. Intrinsic stress can be acutely and chronically experienced by a person. The varying effects of stress on performance or stress hormones are often compared to or known as "inverted-u" which induce areas in learning, memory and plasticity. Chronic stress can affect the brain structure and cognition.

Studies considered the effects of both intrinsic and extrinsic stress on memory functions, using for both of them Pavlovian conditioning and spatial learning. In regard to intrinsic memory functions, the study evaluated how stress affected memory functions that was triggered by a learning challenge. In regard to extrinsic stress, the study focused on stress that was not related to cognitive task but was elicited by other situations. The results determined that intrinsic stress was facilitated by memory consolidation process and extrinsic stress was determined to be heterogeneous in regard to memory consolidation. Researchers found that high stress conditions were a good representative of the effect that extrinsic stress can cause on memory functioning. It was also proven that extrinsic stress does affect spatial learning whereas acute extrinsic stress does not.

The Vinegar Tasters (三酸圖; 'three sours'; 嘗醋翁; 'vinegar tasting old-men'; 嘗醋圖, 尝醋图) is a traditional subject in Chinese religious painting. The allegorical composition depicts the three founders of China's major religious and philosophical traditions: Confucianism, Buddhism, and Taoism. The theme in the painting has been interpreted as favoring Taoism and critical of the others.

The three men are dipping their fingers in a vat of vinegar and tasting it; one man reacts with a sour expression, one reacts with a bitter expression, and one reacts with a sweet expression. The three men are Confucius, Buddha, and Laozi, respectively. Each man's expression represents the predominant attitude of his philosophy: Confucianism saw life as sour, in need of rules to correct the degeneration of people; Buddhism saw life as bitter, dominated by pain and suffering due to desires; and Taoism saw life as fundamentally perfect in its natural state. Another interpretation of the painting is that, since the three men are gathered around one vat of vinegar, the "three teachings" are one.

The "Dokkōdō" (Japanese: 獨行道) ("The Path of Aloneness", "The Way to Go Forth Alone", or "The Way of Walking Alone"), is a short work written by Miyamoto Musashi a week before he died in 1645. It consists of 21 precepts. "Dokkodo" was largely composed on the occasion of Musashi giving away his possessions in preparation for death, and was dedicated to his favorite disciple, Terao Magonojō (to whom the earlier Go rin no sho [The Book of Five Rings] had also been dedicated), who took them to heart. "Dokkōdō" expresses a stringent, honest, and ascetic view of life.

The 21 precepts of Dokkodo:

1. Accept everything just the way it is.

2. Do not seek pleasure for its own sake.

3. Do not, under any circumstances, depend on a partial feeling.

4. Think lightly of yourself and deeply of the world.

5. Be detached from desire your whole life long.

6. Do not regret what you have done.

7. Never be jealous.

8. Never let yourself be saddened by a separation.

9. Resentment and complaint are appropriate neither for oneself or others.

10. Do not let yourself be guided by the feeling of lust or love.

11. In all things have no preferences.

12. Be indifferent to where you live.

13. Do not pursue the taste of good food.

14. Do not hold on to possessions you no longer need.

15. Do not act following customary beliefs.

16. Do not collect weapons or practice with weapons beyond what is useful.

17. Do not fear death.

18. Do not seek to possess either goods or fiefs for your old age.

19. Respect Buddha and the gods without counting on their help.

20. You may abandon your own body but you must preserve your honour.

21. Never stray from the Way.

World on a Wire (German: Welt am Draht) is a 1973 West German science fiction television serial, starring Klaus Löwitsch and directed by Rainer Werner Fassbinder. Shot in 16 mm, it was made for West German television and originally aired in 1973 in ARD as a two-part miniseries. It was based on the 1964 novel Simulacron-3 by Daniel F. Galouye. An adaptation of the Fassbinder version was presented as the play World of Wires, directed by Jay Scheib, in 2012.

Its focus is not on action, but on sophistic and philosophic aspects of the human mind, simulation, and the role of scientific research. A movie based on the same novel titled The Thirteenth Floor starring Craig Bierko was released in 1999.
