Silnik bezszczotkowy prądu stałego, silnik BLDC () – rodzaj silnika elektrycznego, sam silnik jest silnikiem synchronicznym, w którym nieruchome i umieszczone w magnetowodach cewki są zasilane impulsami prądu przez układ elektroniczny zwany elektronicznym komutatorem. W wirniku znajdują się magnesy i w niektórych modelach pręty przewodzące prąd tworzące obwód zamknięty jak w silniku asynchronicznym klatkowym.

W zależności od konstrukcji i sposobu sterowania jego praca jest podobna do silnika synchronicznego z magnesami trwałymi (PMSM), może być również krokowym silnikiem reluktancyjnym lub silnikiem indukcyjnym (asynchronicznym).

Elektroniczny komutator zasilany jest prądem stałym. Układ komutatora kolejno włącza i wyłącza cewki, tworząc wirujące pole magnetyczne, powodujące obrót wirnika.

Silniki bezszczotkowe, których układ elektroniczny jest zasilany prądem przemiennym są nazywane silnikami inwerterowymi.

Zaletami silnika bezszczotkowego w porównaniu z silnikami szczotkowymi są: wysoki stosunek mocy do masy, duża prędkość, prawie natychmiastowa kontrola prędkości i momentu obrotowego, wysoka wydajność i niskie koszty utrzymania. Silniki bezszczotkowe znajdują zastosowanie w takich miejscach, jak komputerowe urządzenia peryferyjne (napędy dysków, drukarki), ręczne elektronarzędzia i pojazdy, od modeli samolotów po samochody. W nowoczesnych pralkach bezszczotkowe silniki prądu stałego umożliwiły zastąpienie gumowych pasków i skrzyń biegów konstrukcją z napędem bezpośrednim.

Zasada działania silnika
Podstawą działania silnika BLDC jest, podobnie jak w wielu typach silników elektrycznych, wzajemne oddziaływanie pól magnetycznych stojana i wirnika. W tym silniku pole magnetyczne stojana jest wytwarzane przez uzwojenia nawinięte na rdzeniu z materiału ferromagnetycznego. Wirnik jest magnesem trwałym, dzięki czemu nie ma potrzeby doprowadzania prądu do wirnika, tak jak to robione przez szczotki i komutator w silniku szczotkowym. By w miarę obrotu wirnika silnik wytwarzał moment obrotowy, pole magnetyczne wytworzone przez cewki musi obracać się. Przełączanie uzwojeń silnika określane jest jako komutacja elektroniczna, a układ to realizujący komutatorem elektronicznym.

Schemat zastępczy

W podstawowej konstrukcji silnika, cewki stojana tworzą układ trójfazowy połączone w gwiazdę. Odpowiednie podłączanie uzwojeń tworzy pole magnetyczne w przybliżeniu prostopadłe do pola magnetycznego magnesów.

Uzwojenie każdej fazy ma indukcyjność (L), rezystancję (R), a ruch względem magnesu wytwarza w nim siłę elektromotoryczną (przeciwelektromotoryczną) (UG).

W idealnym silniku BLDC przebieg generowanej w uzwojeniu siły elektromotorycznej ma kształt trapezu, jej wartość jest proporcjonalna do prędkości obrotowej wirnika. Związek siły elektromotorycznej z obrotami silnika określa parametr silnika zwany stałą siły przeciwelektromotorycznej:

gdzie:
  – wsteczna siła elektromotoryczna,
  – stała siły przeciwelektromotorycznej
  – prędkość obrotowa.

Wartość momentu obrotowego jest proporcjonalna do natężenia prądu pobieranego przez silnik, jej wartość określa wzór:

gdzie:
  – moment obrotowy,
  – stała momentu obrotowego,
  – natężenie prądu pobieranego przez silnik.

Komutacja

Do przełączania uzwojeń (komutacji) synchronicznie z obrotem wirnika stosuje się metody czujnikowe i bezczujnikowe. W metodzie czujnikowej na wale silnika instaluje się układ magnesów trwałych odpowiadający układowi magnesów głównych. Pole magnetyczne odczytuje się używając halotronów o liczbie równej liczbie faz (tu trzy), tylko w najprostszych konstrukcjach niewielkiej mocy tylko jeden. Stosuje się także układy optyczne rozpoznawania położenia wału. Zasilanie uzwojeń silnika realizowane jest przez układ W układzie trójfazowym szeregowym w zależności od stanu czujników położenia (H1, H2, H3), jedna faza silnika jest podłączana do bieguna dodatniego (+), jedna do ujemnego (-), a jedna jest odłączona (z). W wyniku czego prąd płynie przez dwa uzwojenia.

Komutacja czujnikowa wymaga instalowania w silniku układu magnesów i halotronów oraz połączenie ich ze sterownikiem. Układ ten komplikuje konstrukcję i bywa zawodny, dlatego stosuje się konstrukcje nie zawierające czujników położenia wału. Taka metoda sterowania nazywana jest bezczujnikową, które dzieli się na kilka grup:
 wykorzystujące pomiar siły elektromotorycznej uzwojeń,
 wykorzystujące pomiar prądów i napięć oraz równania opisujące silnik,
 wykorzystujące sterowanie rozmyte, w tym i sieci neuronowe.

Precyzyjne przełączanie uzwojeń umożliwia dokładną kontrolę prędkości obrotowej i momentu obrotowego silnika.

W celu uzyskania dużego momentu obrotowego, a tym samym i mocy silnika magnesy wirnika i cewki stojana są układami wielobiegunowymi.

Regulacja
Po podłączeniu uzwojenia prąd w nim narasta, szybkość wzrostu natężenia prądu ogranicza indukcyjność cewek uzwojeń i siła elektromotoryczna (przeciwelektromotoryczna) powstająca w wyniku ruchu magnesów wirnika w pobliżu cewki, oraz rezystancja uzwojeń i zasilania. Przebieg natężenia prądu jest analizowany, a po osiągnięciu wartości maksymalnej, przepływ prądu jest przerywany, by chronić tranzystory mocy i silnik. W układach o zmiennym bądź nieznanym w obciążeniu, a także w celu nadania odpowiedniej charakterystyki silnikowi układ ograniczania mocy uwzględnia prędkość obrotową silnika i jej zmiany. Ograniczenie jest realizowane przez okresowe przerywanie przepływu prądu. W tym celu stosuje się modulację o stałej częstotliwości a zmiennej szerokości impulsów oraz metodę histerezy, w której odchylenie natężenia prądu od zadanego o wartość histerezy powoduje włączenie lub wyłączenie tranzystorów mocy. W obu technikach stosuje się twarde albo miękkie przerywanie prądu. W technice twardej włączane i rozłączane są jednocześnie tranzystory fazowe i zerowe, w technice miękkiej tranzystory zerowe są załączane tylko komutacją, a fazowe komutacją i ograniczeniem prądowym. Stosowanie do ograniczania natężenia prądu układu impulsowego, w porównaniu do sterowania liniowego, poprawia sprawność silnika i umożliwia lepsze jego sterowanie.

Porównanie do silników szczotkowych
Główną zaletą silników bezszczotkowych jest dużo wyższa trwałość i niezawodność wynikająca z wyeliminowania z konstrukcji szczotek, będących najczęstszą przyczyną awarii oraz najszybciej zużywającym się elementem mechanicznym silnika. Dzięki temu jedynym zużywającym się elementem silnika są jego łożyska. Eliminacja szczotek zapewnia cichszą pracę silnika oraz wyższą sprawność energetyczną. Dodatkowo konstrukcja silników bezszczotkowych umożliwia zastosowanie szczelniejszych obudów, gdyż ciepło z cewek może być odprowadzane bezpośrednio poprzez obudowę, co eliminuje konieczność zapewnienia cyrkulacji powietrza. Kolejną zaletą silników bezszczotkowych jest możliwość kontroli prędkości obrotowej prawie niezależnie od momentu silnika. Główną wadą silników bezszczotkowych jest wyższy koszt produkcji. Wynika on z konieczności zastosowania specjalnych sterowników elektronicznych.

Zastosowanie
Ze względu na niezawodność oraz możliwość sterowania prędkości silniki bezszczotkowe są stosowane w napędach dysków optycznych (CD, DVD, BD), dyskach twardych, gramofonach, większości pojazdów o napędzie elektrycznym (np. segway, samochodach hybrydowych), wentylatorach komputerowych i urządzeniach w których iskry powstające na szczotkach mogłyby doprowadzić do zaprószenia ognia czy wybuchu. Dzięki możliwości stosowania szczelniejszych obudów oraz możliwości lepszej kontroli są one również popularne w ogólnie rozumianym modelarstwie zdalnie sterowanym.

Obecnie silniki bezszczotkowe stosuje się coraz częściej do budowy elektronarzędzi akumulatorowych uzyskując zwiększenie ich wydajności.

The Struggles of Syria's Christians
By Greg Kandra

With the situation in Syria worsening by the day, Tom Gallagher of the National Catholic Reporter this week interviewed by e-mail CNEWA's Issam Bishara, regional director for Lebanon, Syria and Egypt. Based in Beirut, Bishara offered a comprehensive assessment of what is happening to Christians in the region:
NCR: What is the current situation at this time for Christians in Syria, who make up about 10 percent of the 2.5 million population?
Bishara: The majority of Christians in Syria are not concentrated in one specific geographical area, but are rather dispersed all over the country, which makes their security situation more critical. However, at present and with only the exception of the Christians of Homs, the majority of Christians remained in their communities and in their homes. But as we knew from different sources related to the church, the Christian families started looking for a contingency plan consisting of finding a safer place for their families in case the uprising and the military events escalated all over Syria, with the same scenario as Homs.
Christians in Syria are in a difficult spot because if they support the protestors, they could be targeted by Assad's government forces, and if they support Assad, and his regime falls, they could be retaliated against by a new Islamist regime. So what are Christians currently doing during this conflict?
During this conflict, the majority of church leaders from different confessions and rites expressed their concern toward the escalation and violence and the repercussions on the minorities, and called their communities to remain calm and to avoid taking sides in this conflict, whether against the regime or against the protesters.
But the general feeling among the Christian communities is a deep concern based on the reality that where the Arab Spring has flourished, political life has become more fanatic and less tolerant of recognizing equal rights for Christians. Even Tunisia, where the former regime was based on a complete secular approach and tradition for more than 50 years, turned into an Islamic-dominated government, and just yesterday, large demonstrations there were calling for the establishment of a full Islamic state.
Have Christians been specifically targeted by Assad and his government forces?
No. On the contrary, the regime is still providing protection to the Christian communities in almost all places where the regime is still controlling the ground. But the problem occurred especially in Homs after the protestors and the Islamic groups had controlled a part of the city (Bab Amro Quarter) where around 200 Christians were killed. The other concern is related to terrorism, which can target anyone and any place and especially Christian military officers and their communities.
The city of Damascus is important historically and has religious significance for Christians. The city has also been a city tolerant of religious minorities. Is this still the case or have things changed for the worse for Christians during this conflict?
Damascus and Aleppo, the two largest cities of Syria, remained relatively well-secured and controlled by the Syrian regular forces, and all Christians in those cities are still enjoying their freedom and practicing their faith as regular.
On Feb. 24-25, the ancient St. Virgin Mary Church was damaged in the fighting in Homs. Can you tell us more about that?
St. Mary Church of the Holy Belt is located in the downtown of Homs, or what is so-called "the Old City," and is considered the siege of the Syrian Orthodox Archdiocese of Homs. The majority of churches and Archbishoprics of other confessions are also concentrated in the same surrounding (Hamidiya, Boustan el Diwan, etc.), and this quarter was subject to military confrontations between the militias and the government forces, and most of the time militiamen were using the churches and the Christians as shields to protect themselves from shelling. It is also important to mention that some icons inside the churches were damaged on purpose by the militias.
With so much fighting going on, many people are leaving their homes in order to find refuge in safer areas. Is this the case with Christians, especially those Christians in and around Homs? If so, where are Christians going to seek refuge?
Despite the difficulties of getting accurate statistics from the field, our updated information estimates that before the military escalations in Homs, the Christians used to number around 1,500 families (all rites). At present and after two weeks of the withdrawal of the militias from Bab Amro, the security situation is still very critical, especially with all the sniper fire on the civilians and the army on one hand and the acts of pillage on the other hand.
A religious sister told us this morning that the 500 families who left their houses during the battle and found shelter in Tartous and Damascus found their houses and properties completely stolen or even confiscated.
The families who decided to remain are in danger, are living in fear and poverty. Most of them cannot go outside their dwellings because of sniper fire, and of course none of them have any kind of income; the only reason they stay in Homs is to preserve their properties and because they have no other place to go to.
There's much more at the NCR link. And you can read more about Syria's Christian Valley in the January 2011 issue of ONE.

Xblaze Lost: Memories review for PS Vita, PS3
PS Vita, PS3, Reviews
by Matthew Pollesel
Platform: PS Vita
Also On: PS3
Publisher: Aksys Games
Developer: Arc System Works
Medium: Digital/Vita Card/Disc
ESRB: M
Xblaze Lost: Memories may just be the most niche game I've ever played. It's a sequel to Xblaze Code: Embryo, which itself was a spin-off from the Blazblue fighting game universe. Except…it's not a sequel, so much as it's a retelling of the events of the first game, only with a little more detail. In other words, it's a game specifically for people who not only love BlazBlue so much that they just must know its origins, but who also didn't feel those origins were told in sufficient detail the first time around and are desperate for even more information.
I'm not sure there's anything in my life — game-related or otherwise — that I'm quite that obsessed with.
I know that I certainly didn't leave Xblaze Code: Embryo feeling like I had to know more. One time was more than enough, in fact. It was a neat little curio, sure, and I liked how it was basically a branching Choose Your Own Adventure story in video game form, but I can't say that I was staying up at night, agonizing over some loose plot threads. The existence of Xblaze Lost: Memories, however, would seem to suggest that my experience was a bit of an anomaly, and that there were a sufficient number of people out there who wanted to know more to warrant this game's release and localization.
Will they be satisfied with this? I honestly have no idea. From the perspective of someone who questions why the game exists in the first place, though, I can't say I get it. In fact, Xblaze Lost: Memories actually kind of annoys me, since not only does it retell Code: Embryo in extreme detail, it does so at the expense of a frame story that seems to be a whole lot more interesting. Lost: Memories takes an easy-to-understand story about a girl trying to get her sister back and mucks it up with…well, literally everything that happened in Code: Embryo, and then some.
Not only that, it throws in all kinds of extra interactivity, as it to bury the interesting plot even further. On the one hand, I do appreciate that they expanded the gameplay beyond "Press X to continue", since that was kind of dull. On the other hand, the way they do so is by introducing the concept of Memory Fragments (which aren't that difficult to find and collect) and pop quizzes on the story so far (which are never all that difficult, since you have an infinite number of opportunities to retake the tests every time you get a question wrong). The latter seems to be there for the sole purpose of padding the game's length, while the former exists in an odd place: it's mandatory to pick them all up, but not mandatory to watch them. I did, of course, since they're kind of the point of the game, but it's a little bizarre to think that anyone would pick this game up unless they really wanted to know the full Code: Embryo story.
Because seriously, I can't think of why anyone else would want to pick up Xblaze Lost: Memories. It's for extraordinarily dedicated Xblaze Code: Embryo fans only — and I don't think I could possibly emphasize that "only" enough, because if that phrase doesn't describe you, you'd be better off picking up literally any other game in existence.

Beauty, Art, and Race
October 29, 2008 Kevin Alfred Strom
by Kevin Alfred Strom (American Dissident Voices broadcast of October 2, 2004)
TODAY I'VE BEEN READING a book entitled Personal Beauty and Racial Betterment. The book is very rare today. It was published in 1920, during that hopeful time when a strong and mostly-healthy America was awakening to the scientific truths about race and the infinite possibilities of racial progress. Knight Dunlap, the author, was a professor of experimental psychology at Johns Hopkins University in Baltimore, and a substantial portion of his book was delivered by him as a lecture at Randolph-Macon College, just down the road from me in Lynchburg, Virginia. Despite some faults, the book is insightful and inspiring.
Dunlap, who later went on to head the psychology departments at both Johns Hopkins and UCLA, says much in his book that would get him hooted off the stage by the equalitarian thugs who dominate the academy today. Dunlap's thesis is that what we call personal beauty is really the emotional appreciation of the many qualities which make an individual a fit and healthy parent for a fit and healthy next generation of our race.
Beauty, then, is more than just something that thrills the lover and the poet — though it is assuredly that.
Dunlap tells us that beauty is "something which… is for the race and for civilization of such profound importance that no other fundamental consideration of human welfare and progress can be divorced from it."
Beauty is a measure of racial fitness for the future. Men and women ache for it in their mates, even if they do not understand the nature or significance of their ache and their passion. The desire for a beautiful mate is an ineradicable, primordial urge. It is an instinctive part of us. It guides us on our recently-interrupted upward journey to higher intelligence, greater strength and power, and increased consciousness and wisdom.
Dunlap says that the preservation of beauty is inseparable from the preservation of all civilized values and progress. Lose one and you lose the other. And further, Dunlap warns, our civilization is fostering an increase of human ugliness and a withering away of human beauty so drastic that only strenuous and radical changes will suffice to reverse it. This was in 1920, mind you — things have gotten far worse since then.
And so this is the theme of today's program: beauty and its significance to the race. I shall go a little beyond Dunlap's subject, which was strictly the beauty of the person, and also discuss the beauty of our surroundings, particularly the beauty of art, which is also withering away in today's multiracialist society.
Personal Beauty
What is beauty of the person? Dunlap tells us that it varies distinctly from race to race, so that such concepts cannot be accurately compared across racial lines, though he acknowledges that darker races sometimes change their standards when influenced by Whites, and some even come to desire White mates — a phenomenon with which we are all too familiar in our century. Dunlap states:
"The broad flat nose and thick wide lips are often repulsive [to us] because they suggest the African, if for no other reason….
"Among certain African tribes, whose men are uniformly over seven feet tall, and as thin as a rail, a normal Anglo-Saxon is probably not beautiful. Among other African tribes, and certain Islanders of the Pacific, a woman is not considered beautiful unless she reaches a degree and a distribution of fatness which makes her either repulsive or comical to European eyes….
"[But] the type which is highest in value tends to approximate the European type, wherever the European type becomes known. All dark races prefer white skin, and it is a general rule that the female of the inferior race prefers the male of the superior race to the male of her own race, no matter how striking the difference. That the inferior male considers the superior female more beautiful than the female of his own race is indicated everywhere, and clearly demonstrated among the Turks."
Dunlap is highlighting one danger of multiracialism: the unique racial standards of beauty and sexual attractiveness held by each race can break down when there is prolonged contact. Whether this unnatural attraction for mates of a higher kind is some kind of instinctive longing for what is greater and better, a primitive proclivity to improve one's stock by mating upward, or whatever, it nevertheless represents a great danger — and no benefit whatever — to the higher race. The danger is particularly acute if many members of the higher race are characterized by out-group altruism and empathy.
What is personal beauty for us? My answer must be very abbreviated and incomplete, but we can trace the outlines.
Personal beauty first consists in the lack of a number of negative characters. It is lack of deformity. It is lack of visible weakness or sickness. It is lack of extreme thinness or obesity. It is lack of a slack-jawed or moronic appearance. It is lack of body or limb size wildly outside the norm. It is the lack of misplaced sexual characteristics — femininity in men is undesirable, as is masculinity in women.
For the woman, stature and strength greater than her own rank high in her estimate of male beauty (as long as the man's stature is not far beyond the norm) — both signs of a man who can protect and provide. And the most attractive man for the single woman is usually one who is sufficiently young to have years of vigor ahead, so he will still be strong when the couple's offspring are almost grown — even though his age may be considerably greater than the woman's in some cases.
For the man, the woman's body is beautiful which has the harmonious swelling of the hips and breasts so much celebrated in art, and the perfect softness of the skin (which shows not too little nor too much underlying fatty tissue), the glowing complexion, and the vivacity and energy that together show a healthy ability to bear and nurture children. The greatest sexual beauty is found in the woman in her child-bearing years.
And there are a great many characters of beauty which apply to both sexes. In some cases, these marks of beauty are also marks of an advanced race, characteristics which signify the greatest possible difference from more primitive forms.
Facial angle: from Edwin J. Houston, The Elements of Physical Geography, for the use of Schools, Academies, and Colleges
Looking at the profile of the face, we note the facial angle (the angle, relative to the horizon when a man is standing normally, of a line drawn from the greatest protuberance of the jaw to the most prominent part of the forehead). The average facial angle of the European race is the closest to vertical of any human race. We also see that non-human creatures have lower and lower facial angles as we make our way from the more advanced to the more primitive. Less-advanced and smaller-brained creatures (and races) have a lower, more sloping forehead (and hence less capacity in the frontal regions of the brain). More primitive races and creatures also tend to have larger teeth, and larger jaws which jut forward, thus making the facial angle even closer to the horizontal.
The man or woman with a high or 'noble' forehead is better-looking to us than a man or woman with a steeply-sloping forehead, which we instinctively view as primitive and ugly, whether we use those words or not. The protruding jaw, so common in Africans and Australasians, or the underdeveloped chin and outsized nose common to some Semites, to European eyes give the human profile a convex and snout-like appearance, and hence are bars to beauty as we perceive it. We may not be conscious of the reason, but our instincts, our souls if you will, are telling us that the highly-evolved is beautiful and the primitive-looking is not.

The most primitive human races have rather stiff and kinky hair, and so, to the European, softly curling, waving, or smoothly soft and straight hair are the most beautiful. Again, we instinctively admire the advanced traits and shrink back from the primitive.
Dunlap tells us that the eyes are special beauty marks, though the precise analysis of why or how that is so — why we instinctively feel that the eyes are expressive windows on the soul — is a subject that needs further study:
"Aside from the indication of physical condition which the eyes afford (and every physician makes use of these indications), the importance of the eye is probably largely racial. The blue or the black, the large or the small, are not in themselves of moment, but they indicate stocks from which we expect certain other characters, mental and physical."
The eyes of the people of our race range from brown to the lightest hues, but I think that in general our race possesses — not exclusively, but more than any other on average — the quality of clarity of the eyes, of whiteness of the orbs when healthy, and of translucency of the iris so that the colored matter is visible clearly through the cornea. This is what gives our eyes an expressive and lucid quality which we see as beautiful.
The cast of the expression of the human face may be the most important single factor in personal beauty. Even in classical art, where the ideal of European beauty is literally set in stone and the entire nude form is revealed, it is still the sublimely high and spiritual expression of the face which arrests our attention more than any other single quality. Dunlap tells us:
"The voluntary muscles of the face, scalp, trunk, arms, and legs are kept in a condition of tonus by nerve currents constantly supplied to them by the motor nerves. Tonus is a state of partial contraction, which constitutes the state of readiness for action of the muscle. If the motor nerve trunk which supplies any voluntary muscle be severed, the muscle at once becomes flabby. …the muscle must be in the appropriate chemical condition to receive the stimulus, and this chemical condition is dependent not only on the general metabolic conditions of nutrition, fatigue, and rest, but also on the specific actions of hormones…."
The face is the site of the most complex muscle structure anywhere on the body, with a complex nerve structure to match, thus giving our faces an extremely wide and subtle variation of expression. With the dependence of these many muscles on the structure, health, and current state of the nerves, it is not surprising that we can learn much of the temperament, state of health, and intelligence of a man or woman by looking at his or her face. The face, and to a lesser extent, the other parts of the body, are giving us a constant and multifaceted 'readout' of the brain and nervous system within.
The 'look' that we call beauty is partly composed of an harmonious arrangement of these complex muscles, combined with an overall poise of the body — both achievable only in a healthy organism with a healthy nervous system.
Of course, we find that our instinctive ideals of beauty — not only as expressed in our sexual selection, but also in our art when it was uncorrupted and free — far outstrip reality in these regards. Very few of us embody all these ideals anywhere close to perfection, though on average we approach them more closely than any other race. But they are our ideals, and insofar as those ideals are favored in our selection of who will be the mothers and fathers of generations to come, they will indeed be a glimpse of those unborn generations, a glimpse of what will be, a glimpse of the future.
The Death of Beauty
We also find that in modern society, it is the highest and most intelligent and most beautiful who effectively sterilize themselves and have the fewest children. It is the best among us who have the most urgent and difficult career tasks to perform; the least time for children. It is largely the bright and the beautiful who are siphoned off to be used and abused by the 'entertainment industry' in their prime parenting years, and who are the most likely to be able to 'arrange things' for the consumerist ideal of a life of trinkets, gadgets, indolence, indulgence, and childlessness. To the dull and the dark come the largest families, these days.
We are effectively exterminating the beautiful.
Part of this problem is due to anti-natal propaganda (which has its greatest effects on the intelligent and responsible), to be sure, and the intensive promotion of every kind of sexual activity except the kind that leads to offspring. But much is due to the simple collision of modern reproductive technology with selfishness and laziness and shortsightedness. (When Margaret Sanger promoted birth control in the early part of the last century, she honestly believed it would relieve the misery of the underclass — and simultaneously have a eugenic effect — because the genetically poorly endowed would still be rational enough to see the quality-of-life benefit in having fewer children. She was wildly optimistic. On balance, it is the responsible and intelligent who limit their numbers. The irresponsible and stupid are as profligate as ever. The effect of Sanger's crusade has been the opposite of what she intended: It has been dysgenic.)
Our social policies — which greatly reward the childless career woman who spends her life, say, overseeing the making of landfill-destined widgets in a Chinese factory, and which also reward the borderline-retarded semi-savage who can increase her tax-money handout by having a seventh child — are also dysgenic in the extreme. The same policies essentially punish the intelligent White woman who has Tommy and Sally and Jenny instead of having a position on the board of the widget company or a corner in the crack house. That has got to stop.
By essentially killing off and sterilizing our best and multiplying our worst, we are killing beauty and killing ourselves. We are doing the exact opposite of what Nature is urging us to do.
Multiracialism also leads directly to the death of beauty in art. Different races have vastly different ideas of beauty. Michelangelo did not produce African masks. Chopin did not write rap or beat on hollow logs. John William Waterhouse and Jackson Pollock inhabited very different inner worlds. In a multiracial society, standards and traditions are abandoned — White standards are too "Eurocentric," and no group can impose its standards on any other nor even hold on to its own traditions for long. In painting, sculpture, architecture, music, literature, and the decorative arts, there is no center any more. The continuity of thousands of years is broken. There is chaos.
Out of it all, a bland, offensive-to-no-one, make-it-as-cheaply-as-possible artistic ethos invades our lives from every side, coupled with an "avant-garde" which revels in the equally-empty perverse. As we begin to live in a society of ugly people, we also see ugly paintings, ugly advertisements, ugly clothing, ugly body deformations and decorations, and ugly buildings everywhere we look. A people disconnected from its own traditions of beauty, a people inundated with the bland and ugly — mixed in with the weird and trendy and ugly — is sickened and greatly weakened.
As I've said before on this program: White children need White art. We need to inculcate a feeling for the highest kind of beauty — our kind of beauty — in our children from the very first day of their lives. In every direction we turn, we should see or hear something beautiful. Most important is the beauty of the human body, European man and woman portrayed in art that exalts and worships, but never degrades.
Beauty Speaks to Us
When romantic love first strikes a man and a woman, beauty speaks loudly: The lovers may consciously think or say, my beloved has beauty, but aeons-old instincts are saying at the same time he is strong and wise and will make a good father; she is bright and fertile and life-giving and will make a good mother. And also they are saying of the loved one that he or she is a fine example of my own kind, a perfect match for me. That is what Nature is telling us with that rush of love and beauty that greets us in our youth.
And Nature is right. We as individuals have lives that are too short for the tasks that Nature is trying to accomplish. Nature needs generations upon generations to reach her goals, the ultimate ends of which even our best minds cannot see, though we know the path leads upward. And so that wisdom, that strength, that vitality, that intelligence, that character — that beauty that our race still possesses — must be carried on from generation to generation, getting stronger, or at least not diminishing, if we are to reach that destiny, if we are not to prove ourselves to be one of Nature's dead ends who failed to do what must be done to survive. Beauty is Nature's way of giving us that message on an emotional level.
I believe that for our race to follow that upward path, for us to maintain the strength it will take to endure the trials of competition with other races and the unknown disasters of the future, we must treasure that beauty and increase it every year, every day. We must build a culture of European beauty and splendor so we shall ever have before our eyes and in our ears the beauty that we and only we can create. If we do that, we shall never forget that our primary purpose on Earth is to bring forth the future generations of our uniquely beautiful race.

Lobsters versus right whales: The latest chapter in a long quest to make fishing more sustainable
Maine lobster fishermen received a Christmas gift from Congress at the end of 2022: A six-year delay on new federal regulations designed to protect critically endangered North Atlantic right whales.
The rules would have required lobstermen to create new seasonal nonfishing zones and further reduce their use of vertical ropes to retrieve lobster traps from the seafloor. Entanglement in fishing gear and collisions with many types of ships are the leading causes of right whale deaths.
Maine's congressional delegation amended a federal spending bill to delay the new regulations until 2028 and called for more research on whale entanglements and ropeless fishing gear. Conservationists argue that the delay could drive North Atlantic right whales, which number about 340 today, to extinction.
This is the latest chapter in an ongoing and sometimes fraught debate over fishing gear and bycatch – unintentionally caught species that fishermen don't want and can't sell. My research as a maritime historian, focusing on disputes tied to industrial fishing, shows the profound impacts that particular fishing gear can have on marine species.
Disputes over fishing gear and bycatch have involved consumers, commercial fishermen, recreational anglers and environmentalists. With conservation pitted against economic livelihoods, emotions often run high. And these controversies aren't resolved quickly, which bodes poorly for species on the brink.
Millions of tons wasted
Bycatch is difficult to measure. Estimates vary widely, but scientists have calculated that 10% to 40% of total yearly catches worldwide are species that weren't targeted, including fish, whales, dolphins, turtles and seabirds.
According to the United Nations, global fishery harvests totaled 178 million tons in 2020. Even by the most conservative estimates, then, some 20 million tons are likely wasted annually. Advocacy focuses on high-profile species like sea turtles, dolphins and sharks, but the problem is much more pervasive. Recent studies of U.S. Atlantic fisheries indicate that flounder, herring and halibut are among the species most frequently landed as bycatch.
At the same time, global demand for fish is rising. From 1961 to 2019, world fish consumption grew by an average of 3% annually, and yearly per capita consumption increased from 22 pounds (10 kilograms) to 46 pounds (21 kilograms). Today, fish consumption is split evenly between aquaculture, or farmed fish, and wild-capture fisheries, where bycatch occurs.
Bycatch is a major global problem that kills fish, marine mammals, sea turtles and seabirds.
Dolphin-free tuna
Most wild-catch fishing takes place far from shore, so bycatch occurs out of the public spotlight. Sometimes, though, threats to charismatic species make news.
Perhaps the most prominent example is U.S. consumers' campaign against the tuna fishing industry for killing dolphins. In the 1950s, tuna fishermen adopted the purse seine – a long, rectangular net that hangs vertically in the water. Boats encircled schools of fish with these nets, then cinched them at the top and bottom. Some nets extended hundreds of feet deep and more than a mile from end to end.
Purse seines often swept up dolphins that swam alongside tuna. Using a method called "setting on dolphins," tuna fishermen would search for pods of dolphin feeding at the surface, which generally indicated that tuna were beneath them feeding as well. By the 1960s, it was estimated that nearly a quarter of a million dolphins were dying every year when they became trapped in nets and suffered traumatic injuries or suffocated.
Logo approved by U.S. regulators in 2000 for tuna caught without targeting dolphins.
When Congress held hearings in the early 1970s on a proposed ban on the capture of all species of whales, including dolphins, this practice sparked outrage. The New York Times accused the tuna industry of "wanton slaughter." Millions of viewers watched televised documentaries with titles like "Last Day of the Dolphins?" and "Where Have All the Dolphins Gone?" Advocacy groups campaigned with slogans like "Would You Kill Flipper for a Tuna Sandwich?" and boycotted canned tuna.
Under pressure, major suppliers including StarKist, Chicken of the Sea and Bumble Bee pledged to use only tuna that was not caught using methods that endangered dolphins. In 1990, Congress passed legislation creating a label that identified canned tuna caught appropriately as "dolphin-safe." Other measures banned tuna imports from countries with dolphin mortality rates higher than those in U.S. fisheries.
Trap doors for turtles
The spotlight next shifted to the U.S. Gulf Coast, where shrimp catches were skyrocketing thanks to gear like otter trawls – large conical nets towed through the water behind fishing boats. By some estimates, for every 1,000 pounds of fish that these nets gathered, less than 100 pounds was marketable shrimp. Other species – usually dead, dying or injured – were tossed overboard.
Environmentalists and recreational anglers accused the fishing industry of endangering popular sport fish, such as red drum and spotted trout. But sea turtles, which often were found in the same coastal waters as shrimp, became critics' poster animal. A 1990 report from the National Research Council estimated that shrimping killed up to 55,000 Kemp's ridley and loggerhead sea turtles yearly.
Federal regulators initially proposed voluntary use of turtle excluder devices, or TEDs – small trap doors in fishing nets that could allow captured turtles to swim free. In 1987, the National Oceanic and Atmospheric Administration published mandatory TED usage regulations, which went into effect in 1989 after several years of lawsuits, injunctions and state legal action.
Turtle excluder devices, or TEDs, direct sea turtles toward openings in shrimp nets that allow the turtles to escape.
Many fishermen argued that TEDs greatly reduced their shrimp catches and resisted the new regulations, sometimes agressively. Over time, however, shrimpers began working with federal regulators to develop and test TEDs that released turtles and retained shrimp more effectively. Today, sea turtles are still at risk, but there is wide agreement that modern TEDs effectively reduce turtle bycatch. Conservation organizations are working to increase their use worldwide.
Slow progress
Fishermen often are quick to rebut claims that their methods endanger other species. They typically assert that their fishing has little impact on the broader ecosystem and that new gear and practices will be too costly or ineffective against a minor problem.
Ultimately, public pressure – including lawsuits – can lead to regulation, especially when a potent symbol like dolphins, sea turtles or, perhaps, right whales, is threatened. The Maine lobster fishery has lost several sustainable certifications because of concerns about right whale entanglements.
But regulation isn't enough. Reducing dolphin and sea turtle bycatch also required extensive engagement between regulators and fisheries to educate fishermen and develop and test gear. It's not clear whether this will happen fast enough to save North Atlantic right whales.
Across broad swaths of the globe, including much of Africa and Asia, more than 3 billion people obtain from 20% to over 50% of the animal protein in their diets from aquatic sources. Rising demand for wild-caught fish is likely to increase bycatch. In my view, unintentional capture of any species – whether it's a winsome spinner dolphin or a bottom-dwelling scavenger like the hagfish – harms the ocean's ecological health and threatens communities that rely on the sea for sustenance.

La genette aquatique (Genetta piscivora) est une espèce de carnivore de la famille des Viverridae. C'est la seule espèce du genre Osbornictis. On trouve cette genette dans les forêts équatoriales d'Afrique centrale. Elle se nourrit essentiellement du poisson qu'elle pêche dans les torrents auprès desquels elle vit (ADW).

La plupart des auteurs anglo-saxons (voir les références ci-dessous) considèrent que ce Viverridé ne peut appartenir au genre Genetta, tellement il en diffère à la fois par sa morphologie spécialisée adaptée à la vie aquatique, par son pelage et les couleurs de celui-ci. C'est ainsi qu'ils maintiennent le genre Osbornictis de la description d'origine de J.A. Allen en 1919.

Dubai seeks French investments in AI, smart solutions
Keywords:DubaiUAE
Dubai is looking to expand its cooperation with French firms in the field of blockchain, artificial intelligence and other innovative technologies, said a senior official in Dubai on Sunday.
"The UAE-France non-oil trade in 2016 reached $21 billion, up 46 per cent from 2010. There is a significant scope to expand collaboration to new sectors like smart city solutions, healthcare, blockhain and innovative technologies. More than 66 French companies have already presence in Dubai Silicon Oasis from where they run their Middle Eastern operations," said Mohammed Alzarooni, Vice Chairman and CEO of Dubai Silicon Oasis Authority.
"Dubai has embarked on a journey to become smartest city in the world. We are committed to play a key role in the ambitious vision of our leadership. We will continue working on developing communities that are based on smart technologies and building communities that provide comprehensive smart living," he added.
Alzarooni was speaking at the inauguration of Innovation Hub on Wheels by French firm Schneider Electric at the Dubai Silicon Oasis on Sunday.
Schneider is showcasing its next-generation EcoStruxure architecture and platform that delivers IoT-enabled open solutions for partners to develop new applications.
Luc Remont, executive vice-president, international operations, Schneider Electric, said: "We see this region growing and the potential for development is very strong which is not completely expressed yet. In order to grow in absolute terms here, we will continue to invest in people and expand industrial footprint which has been driving us in the last 30 years."
He noted that this would strengthen the company's ability to drive the significant part of group's business from Dubai – which is one of the company's four hubs around the world. Its other hubs are Paris, Boston and Hong Kong.
Jean-Pascal Tricoire, Chairman and CEO of Schneider Electric, said that the company has almost equally distributed in North America, Europe, Asia-Pacific and in the Middle East Africa and South America. Osman Sultan, CEO, du, said the world is moving from centralised to decentralised.
Citing examples, he pointed out that now the world's largest taxi – Uber – doesn't own a tax and the world's largest voice operator – Skype – doesn't own network, reflecting how the world is moving from physical to the virtual world.
He said people are at the heart of everything the UAE does. "This is the only country where you have minister of artificial intelligence in parallel with minister of happiness and a minister of tolerance. This is where the country is pioneering and putting the people at the centre of everything."

Eating (and drinking) is inextricably woven into the fabric of our lives. For events mundane and extraordinary food and drink play an inevitable role. When there is a diagnosis of cancer it is not uncommon to explore if how and what we eat can help with cancer treatment and living well with cancer.
The past few years have seen an explosion of information – often conflicting – about the relationship between dietary elements and cancer, especially breast cancer. It can be difficult for the layperson (and the health professional) to determine the relevance and significance of variously sourced information, especially when there are so many aspects of diagnosis and treatment to consider. What is incontrovertible is that eating a healthy, plant-centred diet and engaging in appropriate physical activity will help you keep up your strength, tolerate your therapy and improve your sense of well-being, both during active treatment and beyond.
This short paper seeks to address some of the most commonly considered topics for those living with breast cancer. The advice herewith is for information and consideration only. If you decide to make any changes to your diet, or are having problems with appetite, eating or digestion, please speak to your doctor or hospital dietitian.
For those with secondary disease: Although being at an optimal weight is desirable, overall well-being and energy are of most importance. For some people cutting back on calories and fat can be stressful, tiring or difficult, and without any perceived benefit. If you feel like you need to lose weight discuss this with your doctor or dietitian.
•Planning –healthy and nutritious eating doesn't happen by accident. Make a weekly meal plan and stick with it.
•Cut down or out processed food (even so-called diet foods).
•Eat more plant foods (fruit, veg, pulses, beans, whole grains) – health experts suggest at least 3/4 of the diet should be plant foods and 1/4 of animal origin (including dairy). Vegetables are better for weight loss than fruits (less sugar). Gradually does it though: sudden changes in your normal diet can cause digestive upset in many people.
•Avoid skipping meals (especially breakfast) for better blood glucose and craving control. Breakfast eaters typically weigh less than those who don't.
•Control portion sizes – this can make a big difference, especially with starchy carbohydrates. Using a smaller plate can help us accept smaller portions.
•Join a slimming club if you would benefit from the outside support. Beware of the diet food that is often flogged through these groups though – eat real food but less of it instead of 'diet' biscuits and processed cheese things.
Eat a small salad or slowly sup a bowl of vegetable-based soup before eating your main course. You will probably eat less and still be satisfied.
Low glycemic carbohydrates reduce hunger as they are digested slowly and keep a steady supply of blood sugar (which influences appetite and fat storage). Glycemic load (GL) is a way of measuring how our bodies digest, absorb and use different carbohydrates and is based on serving sizes (unlike the GI – glycemic index – diet). In general the less processed the food the lower the GL. For example, an apple will have a lower GL than stewed apple and both have less than apple juice. Most veg and pulses are low GL. If you stay away from the faddier approaches to GL you'll gradually lose weight and feel great too. There are plenty of books and websites that explain this approach to eating, and the foods that make it happen.
During active treatment you may have eaten more 'treat' foods than you would normally: friends' homebaking, comforting meals to cheer you up, easily swallowed milkshakes and creamy soups. These certainly have their place during treatment when eating what you fancy is the standard – and appropriate – advice from doctors. But post-treatment is for many a time to 'start as you mean to go' – eating well for recovery, and beyond. To do this we often need to re-establish helpful and healthy eating patterns.
A good first step is learning to distinguish between true hunger and appetite. Grazing and nibbling may have been the order of the day during treatment, but in the long-term this way of eating divorces us from the needs of our body. The result can be spiralling weight and diminishing energy and mood. If this sounds like you, try this exercise: after a meal go four hours before eating, even if you feel a bit peckish. Let your tummy start to rumble so that you know what true hunger feels like. Do this a few times over the course of a week, jotting down the circumstances and times that you were tempted to eat during the four hours.
What brought food to mind? Were you bored? Did you detect a nice smell? Did your soap opera come on and you reached for the usual packet of crisps? Can you identify any patterns? How long did it take for the desire to pass? Keep track for a few days and note down the things that you would have eaten had you 'given in'. Tot up the calories, and fat, if possible. This can be a real eye-opener. It is said that breaking ingrained habits takes as little as six weeks. For a month and a half challenge yourself to say no to unneeded snacks and seconds. See if you can break any long-standing unhelpful eating patterns. This can help with weight loss and weight maintenance without resorting to boring old diets. If you are having trouble keeping weight on, obviously ignore all of the above and eat what you ned to be a good weight for yourself: see below for more advice.
Some of you may be concerned about losing weight or being underweight. Just like trying to lose weight, gaining weight can take time. If your appetite isn't up to much, add olive oil (it has a more neutral taste than extra virgin) or cold-pressed rapeseed oil (both are very healthy fats) to your servings of food. Small amounts of butter, whole milk products, hard cheese and even hard-boiled eggs add calories and protein. Avocados, bananas, dried fruits, quality energy bars, nuts and nut butters are healthful ways of getting extra calories without saturated fat and extra hormones. Smoothies and freshly pressed juices deliver necessary nutrients without stomach-filling bulk. See my article on Help With Gaining Weight.
You may also wish to use a dietary supplement to add calories and protein. These include powders to add to your food and stand-alone soups and drinks. Your GP or hospital dietitian can advise on the right product for you – there are many taste varieties and nutrient formulations to choose from. These are available on prescription.
Phytoestrogens are a group of compounds found in varying concentrations in numerous plant foods such as whole grains, green vegetables, beans, pulses, flaxseeds and alfalfa sprouts. Soy beans (edamame) and soy products such as tofu, tempeh, miso, soy milk and soy yogurt are particularly high in phytoestrogens. Supplements containing phytoestrogens have much higher concentrations than are found in food sources. The interest in phytoestrogens is due to their similarity to human estrogen.
2) soy is harmful for those with a diagnosis of breast cancer or those at high risk for breast cancer.
Unfortunately there is no concrete evidence either way, especially with regard to food. It seems probable from the evidence thus far that soy products consumed in a broad and mixed diet are safe. The general advice from most of the scientific literature is that one serving a day in a mixed diet is fine, but some women with estrogen-sensitive disease may be advised by their treatment team to further limit, or eliminate, soy foods Ask your doctor for advice if this is a concern. Most of the scientific literature shows that naturally phyto-estrogen containing foods in a normal diet do not affect breast cells. But, if you are on Tamoxifen or aromatase-inhibitors you will not want to be eating soy foods. Remember that you are blocking/eliminating circulating estrogens of all kinds. Physto-estrogen-containing foods may generally be eaten freely by those with estrogen-negative disease. But again, check with your doctor.
The view on supplemental phytoestrogen is somewhat clearer: most health professionals currently agree that herbal phytoestrogen supplements should not be used by those with breast cancer. Although some women report menopause symptom relief with these supplements their overall effectiveness and safety is not established; soy protein powders used as meal supplements also fall into this category. Again, this may be an issue to discuss with your doctor. Those with estrogen-negative cancer should also discuss supplements if this is relevant to you. There are numerous large studies currently examining soy's impact on cancer so hopefully we will soon have guidelines soon.
Like soy there is some controversy over the part dairy products play in breast cancer. It is not clear whether potential risks of the naturally occurring growth factors present in milk and milk products outweigh the clear benefit of dairy as our best source of absorbable calcium. It is also unclear whether any demonstrated effect is dose-related. It is known that organic dairy products have less total growth factors than non-organic.
Large observational studies of Asian women who move to the West and consume more dairy and less traditional soy products appear to have an increased incidence of breast cancer compared to those who do not make changes. It is unclear how big a part additional 'confounding' factors – such as less exercise and more processed food – play in this generalised finding.
Calcium is vital for bone health and for other functions in the body. Although dairy products are our best source of calcium, some plant foods and soy products, as well as fish also give us calcium. Good sources to include in the diet include whitebait, tinned small fish (sardines, anchovies) and tinned salmon, some leafy green vegetables (watercress, broccoli, kale), dried figs and apricots, baked beans, ground sesame seeds (try tahini), white bread and breakfast cereals (these are fortified). If you rely on non-dairy sources for calcium it is important to vary your sources as described above. Combined Vitamin D and calcium supplementation is an option for those with a limited diet. Ask your doctor for advice.
Some people believe that cancer 'feeds' off of sugar and recommend that people with cancer stop eating sugar (this sometimes includes fruit too). Studies show that people who consume lots of sugar generally do not eat much in the way of fruits and vegetables, and they consume more processed foods and fatty meats. These factors (and others) may account for any apparent increase in cancer risk.
Highly-refined or sugar-laden foods, which are low in nutrients, low in fibre, and high in simple carbohydrates give us calories and little else. Foods high in refined sugars or refined carbohydrates may also increase insulin resistance. It is not clear whether insulin resistance is important in cancer progression.
Taking in enough calories and maintaining energy may be your goal during treatment and beyond. Your doctor or breast care nurse may advise you to include high-calorie foods in your diet in order to meet this goal. Including refined carbohydrates or sugared foods in your diet may help you to maintain weight or gain weight, along with foods that are more typical in a healthy diet. Refined carbohydrates are typically easy to digest and absorb.
Most major cancer centres and research bodies concur that sugar does not cause cancer, nor, despite the claims of some 'alternative' practitioners, does it hasten the growth of cancer cells.
You may have heard or read about some diets or supplements preventing recurrence or stopping cancer in its tracks. Some women feel that they may influence disease control. Although there are numerous theories linking diet causatively and preventatively to breast cancer there is no clear scientific evidence that certain foods or diets will modify disease. The best science-based advice is to strive to be at your optimum weight for your height and age. Although there is interesting anecdotal evidence for some 'anti-cancer' diets, it is advisable to consult a dietitian or your doctor about the pros and cons of various diets. Everyone is different and what suits one person may not suit another.
One a cautious note, some diets used in cancer therapies can cause weight loss and weakness. These diets are characterised by being high in bulk, low in calories and protein, fairly tasteless, difficult to prepare and expensive to follow. Additionally, herbal and non-nutrient supplements can have very strong effects and should only be taken on the advice of someone experienced in advising those with a cancer diagnosis. Those considering an alternative diet or herbal therapy while going through treatment should ideally inform their doctor as both may have implications for treatment.
•Incorporate some walking into your daily routine unless this makes your fatigue worse.
•Keeping up with your protein. Adequate protein helps with tissue building and repair as well as helps to provide energy.
•Getting enough vitamins and minerals, directly from food. If you are experiencing eating or digestion-related difficulties for more than a few days at a time you may wish to discuss with your doctor whether it would be beneficial to supplement your diet with prescribed supplement drinks and/or an appropriate multivitamin.
•Staying well hydrated, especially when undergoing radiotherapy or if you are vomiting or have diarrhoea.
•Asking for help in dealing with stress, anxiety or depression.
•Talking to the hospital dietitian. He or she will be able to advise on any nutrients that you may be lacking and help to create a diet plan that addresses your current and future needs.
"Calcium is vital for bone health and for other functions in the body. Although dairy products are our best source of calcium…." ARE THEY REALLY??? I have seen some documentaries that prove exactly the opposite. More than that – milk, cheese and dairy take calcium out of our body!
Calcium bound in dairy products is the most absorbable form. Too much can indeed leach nutrients out of bones but so can too much (unfermented) soya and too much whole grains, due to phytic acid. If someone is not completely avoiding dairy we usually advise mixed sources, not relying on dairy.
Absolutely! Calcium can be obtained through plants and nuts. Dairy products will fuel breast cancer. They are loaded with hormones – both natural and injected. Growth hormones. Stress hormones. It causes a body to be acidic, which is an environment that cancer thrives in. And while we're at it, sugar can cause and does feed cancer. When you go for a scan you are injected with a radioactive die that is mixed with a sugar substance. It is in this way that the technicians and doctors can see where cancer is in the body when there is an increased uptake in any area. I've been battling my breast cancer completely naturally for two years. It's rule number 1 when you are diagnosed with cancer. No sugar.
This is a terrific site/ blog. We are making small but important changes in my family's meals and this is a very helpful guide.
Thanks for today's event and lunch at Maggie's by WGH. I enjoyed both.
I will email again soon!
You 're very welcome. I'll see you next week.

John Morley Lee (12 October 1825 – 20 January 1903) was an English clergyman and cricketer who played in first-class cricket matches for Cambridge University, Surrey, Marylebone Cricket Club (MCC) and various other amateur teams in the late 1840s. He was born at Chelsea, London and died at Botley, Hampshire.

Family and background
Lee was privately educated at Oundle and then at St John's College, Cambridge. He was the son of a London-based builder, Henry Lee, described as coming from Chiswell Street in Finsbury but later settling in Balham; John Lee's younger half-brother, Frederick, 15 years younger, was also a first-class cricketer, playing for Cambridge University, Surrey and other amateur sides.

Cricket career
As a cricketer, Lee appeared in a couple of matches for Cambridge University in the 1845 season as a tail-end right-handed batsman, but made little impression; he did not take any wickets with his right-arm medium-fast bowling, and scorecards being incomplete for these games it is not clear whether he bowled or not. In his first match of 1846, his round-arm bowling proved decisive with nine wickets in a narrow victory for the university over the MCC. He took 10 wickets in the return match in London, though this was a 12-a-side first-class game. He was then picked for the 1846 University match against Oxford University which was played in Oxford. Later in the 1846 season, Lee played a couple of first-class matches for the Gentlemen of England side.

Lee's success as a bowler continued in 1847 and in the university side's MCC match at Lord's he took seven wickets in the first innings and five in the second, his best figures in first-class cricket (as in most of Lee's matches, the full bowling figures have not been recorded). He played in the University Match for a second time and later in the season played for Surrey, the Gentlemen in the annual Gentlemen v players match at Lord's, and MCC. In his single game for Surrey, he played successfully as a batsman, scoring 40 and 20 in a game with Kent, and appears not to have bowled. There was a similar pattern to Lee's cricket in 1848, his last season at Cambridge and his third appearance in the University match; He appeared for Surrey and for "Gentlemen of England" after the university cricket season ended. But his bowling was less effective in 1848 and he often batted high in the batting order, scoring an innings of 110, by a long way his highest score, in the Cambridge game against the Gentlemen of Kent, when he opened the innings.

Lee played very little cricket in 1849 but returned, without distinction, in 1850 in eight first-class games, including an appearance for the All-England side, and another in the Gentlemen v Players series. He also played in a remarkable South v North match which was scheduled for three days but completed in one day with John Wisden taking all 10 South wickets, including Lee's, in the second innings. He did not play first-class cricket after 1850.

Career after cricket
After graduation from Cambridge University in 1848, Lee was ordained first as a deacon and then as a Church of England priest. He was curate at Long Melford, Suffolk and then at Abbot's Langley, Hertfordshire. In 1855, his father bought for him the benefice of Botley, Hampshire, and he remained as rector there for 48 years to his death in 1903, also acting as rural dean of Bishop's Waltham and from 1877 as an honorary canon of Winchester. In 1855 also, Lee married Emily Mary Gingell of Wood House, East Ham; they had two daughters.

Hoosiers get bigger with Britt Commit
Bloomington, IN — The Hoosiers continues to prepare for the war in the trenches on the defensive side of the ball with big recruits like Defensive Tackle Derrius Mullins and defensive end Britt Beery. Mullins stands 6'4" and weighs in at 340 lbs, while his fellow Indiana commit is an imposing 6'6" and 250 lbs. There's not doubt that the Hoosiers have put a considerable amount of emphasis on making sure their defensive linemen are huge and ready to bully whoever gets in their way.
Britt is another homegrown Hoosier like Bryant Fitzgerald that's looking forward to playing an instrumental role in the Indiana football revival and they are arriving in Bloomington just in time.
The Big 10 is the new SEC. They are by far the most competitive conference in college football and in order to compete with the likes of Michigan, Ohio State, Wisconsin and PSU they're going to need hog mollies like Beery and Mullins to stand tall against these historically dominant programs. And I have a feeling they're up for the challenge.
Britt Beery
Hometown: Carmel, IN
School: Carmel
Highlights from our interview with Beery
Q: Who's your biggest influence when it comes to football?
A: "My dad is my biggest influence in football. He played at a high level in College and his experiences have helped me along the way. He has really encouraged me to work hard and good things will happen, play with confidence, and always be a great teammate!"
Q: What made you choose Indiana over other schools?
A: "Indiana felt right from the beginning of my recruitment. It felt like home to me. I really enjoyed getting to know the coaches and players and building relationships with them.the strong commitment to football and academics along with the fact it is close to home all separated IU from other schools. I'm very excited about the future of IU Football."
Q: What do you plan on majoring in at Indiana in the fall?
A: "Exercise Sciences and communications."
Q: What do you like to do in your free time?
A: " I enjoy hanging out with my family and friends and vacationing with my family and celebrating the holidays and special occasions together. I also play basketball at Carmel and have enjoyed the friendships I've made there. I've never played hockey, but have been a long-time fan of the Chicago Blackhawks and enjoy all different types of music."

Discussion in 'Scripting' started by eses, Feb 13, 2019.
Then I have a bunch of ifs to decide if there's a wall or block in move direction. Finally I check if it has a open door. Only if the direction is not blocked, I allow transition from tile to tile.
Anyone have idea how old school dungeon crawlers and some other types of games handled these?
I bet these didn't use OOP style. Like here I've got a Tile cell, which knows it's neighbor cell tiles and each cell has a list of walls in NESW directions around it.
I haven't found any articles on this topic, but I remember some games that used this kind of tile movement. I was considering also some sort of tile-wall-tile type structure bit like in Pac-Man, but I haven't quite got it right in my head yet.
So I got it working but it feels clumsy and ugly. I feel there must be cleaner way to do this.
Normally the point of a grid is that you know a tile is enterable based on what is in it. You also know the neighbors of a given tile are always +1 or -1 away in each of the four (or eight) directions.
You can continue to do this simple neighboring and traversability, but if you wrap it up in a class, then you can ALSO have other providers of either linkage or blockage, such as these walls between two otherwise-traversable tiles.
But the key is if you wrap it up in some kind of "navigability manager" class, then your underlying maneuver code doesn't have to change: it just asks "can I go from here to here?" and then the nav class can decide based on the state of the map, any doors opening/closing, chasms opening, etc.
In other news, PacMac was a pure grid, but not quite in the way you visually see it as: the cells are actually smaller than the size of the hallways that you navigate.
Here's an AWESOME article on how the PacMan AI worked, and it gives you an insight into how they did such a great game with such limited hardware.
The whole article is a great read for any game developer.
Thanks, I already did mention that I'm aware of Pac-Man tile system, where it is basically tile-wall-tile kind of setup...and I've read that article twice a while ago, however IIRC it was mostly about ghost movement logic, not about map structure. I've yet to read Pac-Man dossier.
I do already have a grid of Tile cells that each know their neighbors, and which edges can be crossed, but the implementation is quite clumsy. And I do have sort of manager for map, that entity in map can query for free positions, possible transition from tile to neighbor tile, but it's not pretty. I'm eventually going to modify it to fit A star (if I have time), but not sure how long this will take. It just bothers me how the doors / non-crossable edges are now sort of special cases, and not map data like walkable/non-walkable tiles. I bet this has been solved in much better way already.
