The underarm bowling incident of 1981 is a sporting controversy that took place on 1 February 1981, when Australia played New Zealand in a One Day International cricket match, the third in the best-of-five final of the 1980–81 World Series Cup, at the Melbourne Cricket Ground.

With one ball of the final over remaining in the match, New Zealand required a six to tie the match. To ensure that New Zealand were unable to achieve this, the Australian captain Greg Chappell instructed his bowler (and younger brother) Trevor Chappell to deliver the last ball to batsman Brian McKechnie underarm along the ground. Trevor did so, forcing McKechnie to play the ball defensively, meaning Australia won. This action, although legal at the time, was nevertheless widely perceived as being wholly against the traditional spirit of cricketing fair play.

The outrage caused by the incident eventually led to an official amendment to the international laws of cricket to prevent it from occurring again.

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.

The National Radio Quiet Zone (NRQZ) is a large area of land in the United States designated as a radio quiet zone, in which radio transmissions are heavily restricted by law to facilitate scientific research and the gathering of military intelligence. Roughly half of the zone is located in the Blue Ridge Mountains of west-central Virginia while the other half is the Allegheny Mountains of east-central West Virginia; a small part of the zone is in the southernmost tip of the Maryland panhandle.

🔗 Crime 🔗 Mining

Sand theft or unauthorised or illegal sand mining leads to a widely unknown global example of natural and non-renewable resource depletion problem comparable in extent to global water scarcity. Beach theft is illegal removal of large quantities of sand from a beach leading to full or partial disappearance of the beach.

🔗 Electronics

In signal processing, the Nyquist frequency (or folding frequency), named after Harry Nyquist, is a characteristic of a sampler, which converts a continuous function or signal into a discrete sequence. For a given sampling rate (samples per second), the Nyquist frequency (cycles per second) is the frequency whose cycle-length (or period) is twice the interval between samples, thus 0.5 cycle/sample. For example, audio CDs have a sampling rate of 44100 samples/second. At 0.5 cycle/sample, the corresponding Nyquist frequency is 22050 cycles/second (Hz). Conversely, the Nyquist rate for sampling a 22050 Hz signal is 44100 samples/second.

When the highest frequency (bandwidth) of a signal is less than the Nyquist frequency of the sampler, the resulting discrete-time sequence is said to be free of the distortion known as aliasing, and the corresponding sample rate is said to be above the Nyquist rate for that particular signal.

In a typical application of sampling, one first chooses the highest frequency to be preserved and recreated, based on the expected content (voice, music, etc.) and desired fidelity. Then one inserts an anti-aliasing filter ahead of the sampler. Its job is to attenuate the frequencies above that limit. Finally, based on the characteristics of the filter, one chooses a sample rate (and corresponding Nyquist frequency) that will provide an acceptably small amount of aliasing. In applications where the sample rate is pre-determined (such as the CD rate), the filter is chosen based on the Nyquist frequency, rather than vice versa.

🔗 Computer science

The Squeak programming language is a dialect of Smalltalk. It is object-oriented, class-based, and reflective.

It was derived directly from Smalltalk-80 by a group at Apple Computer that included some of the original Smalltalk-80 developers. Its development was continued by the same group at Walt Disney Imagineering, where it was intended for use in internal Disney projects. Later on the group moved on to be supported by HP labs, SAP Labs and most recently Y Combinator.

Squeak is cross-platform. Programs produced on one platform run bit-identical on all other platforms, and versions are available for many platforms including the obvious Windows/macOS/linux versions. The Squeak system includes code for generating a new version of the virtual machine (VM) on which it runs. It also includes a VM simulator written in Squeak. For these reasons, it is easily ported.

🔗 Writing systems

A lipogram (from Ancient Greek: λειπογράμματος, leipográmmatos, "leaving out a letter") is a kind of constrained writing or word game consisting of writing paragraphs or longer works in which a particular letter or group of letters is avoided. Extended Ancient Greek texts avoiding the letter sigma are the earliest examples of lipograms.

Writing a lipogram may be a trivial task when avoiding uncommon letters like Z, J, Q, or X, but it is much more challenging to avoid common letters like E, T, or A in the English language, as the author must omit many ordinary words. Grammatically meaningful and smooth-flowing lipograms can be difficult to compose. Identifying lipograms can also be problematic, as there is always the possibility that a given piece of writing in any language may be unintentionally lipogrammatic. For example, Poe's poem The Raven contains no Z, but there is no evidence that this was intentional.

A pangrammatic lipogram is a text that uses every letter of the alphabet except one. For example, "The quick brown fox jumped over the lazy dog" omits the letter S, which the usual pangram includes by using the word jumps.

In radio communications, an evolved antenna is an antenna designed fully or substantially by an automatic computer design program that uses an evolutionary algorithm that mimics Darwinian evolution. This procedure has been used in recent years to design a few antennas for mission-critical applications involving stringent, conflicting, or unusual design requirements, such as unusual radiation patterns, for which none of the many existing antenna types are adequate.

🔗 Greece 🔗 Songs

"Misirlou" (Greek: Μισιρλού < Turkish: Mısırlı 'Egyptian' < Arabic: مصر Miṣr 'Egypt') is a folk song from the Eastern Mediterranean region. The original author of the song is not known, but Arabic, Greek, and Jewish musicians were playing it by the 1920s. The earliest known recording of the song is a 1927 Greek rebetiko/tsifteteli composition. There are also Arabic belly dancing, Albanian, Armenian, Serbian, Persian, Indian and Turkish versions of the song. This song was popular from the 1920s onwards in the Arab American, Armenian American and Greek American communities who settled in the United States.

The song was a hit in 1946 for Jan August, an American pianist and xylophonist nicknamed "the one-man piano duet". It gained worldwide popularity through Dick Dale's 1962 American surf rock version, originally titled "Miserlou", which popularized the song in Western popular culture; Dale's version was influenced by an earlier Arabic folk version played with an oud. Various versions have since been recorded, mostly based on Dale's version, including other surf and rock versions by bands such as the Beach Boys, the Ventures, and the Trashmen, as well as international orchestral easy listening (exotica) versions by musicians such as Martin Denny and Arthur Lyman. Dale's surf rock version was heard in the 1994 film Pulp Fiction.
