SQL Dialects Reference/Select queries/Select without tables

Select without tables
Sometimes one needs to execute SQL scalar expressions without table context, i.e. make a query that would act as normal SELECT operator, evaluate given comma-separated expressions and return a table with single row and one or multiple columns (one for every individual expression). Obviously, expressions can't reference any columns from the tables, as there are none.

An example is determining the value of a mathematical function, using Oracle syntax:

=Philidor Counter-Gambit= The situation is getting complicated. Black deliberately weakened his king-side to keep chances at the center.

 * /4. dxe5/ isn't the best solution. After 4...fxe4, the knight is forced to move to d4 or d2, blocking queen's attack against the Black pawn. Then, Black can rebuild his center with d5. A few games have been tried with 5. Ng5 where Black development is made harder by the White pawn.
 * /4. exf5/ may lead to weird pawn structures in both camps. If 4...exd4 5. Nxd4 White has only an advanced pawn on f file left, while Black has still his d6 pawn (but with a weakened king side).
 * /4. Bc4/ poses the Ng5 threat and Black should remain vigilant for any attempt to launch a Qh5+ attack.

Horticulture/Resistant Varieties

Resistant varieties are plants within a certain group that are less vulnerable to attack by plant pests or diseases. In seed catalogs, these are often indicated by codes, which may vary from company to company.

The use of resistant varieties is strongly recommended if pest or disease issues have arisen in the past.

Horticulture/Otiorhynchus sulcatus

The black vine weevil, Otiorhynchus sulcatus, is native to Europe, but common in North America as well. This weevil is a pest of many garden plants, causing the most damage on evergreen trees and shrubs.

The adult weevil is black with fused wing covers, and is unable to fly. Adults feed at night on the outer edges of leaves, causing the leaves to have a notched margin.

Grubs live below the soil surface, and feed on the roots and on the cambium at the base of the trunk.

Host plants
Host plants include but are not limited to the following genera:
 * ../Arisaema/
 * ../Aster/
 * ../Astilbe/
 * ../Camellia/
 * ../Echinacea/

Cookbook:Low-Allergen Cooking

Allergens
There are many allergens, not all of which are foods, and any food can potentially be an allergen, however some foods are more common causes of allergies than others. There are some particularly common food allergens, warnings of the presence of these in foods are normally in an "Allergy Advice" section underneath the ingredients list on food packaging. Some of the main food allergens are:
 * Nuts
 * Legumes (particularly peanuts and soy)
 * Egg
 * Milk
 * Fish
 * Shellfish
 * Wheat
 * Sesame seeds
 * Corn
 * Maize

Alternative names
Confusingly, when these ingredients are present in foods, although they will be mentioned on the ingredients list there are many different names for some of these. This is normally due to the ingredients specifying, for example, the part of milk present rather than stating 'milk'. This is less of a problem with foods which are mentioned in the allergy advice section. Below are some of the alternative names which can be found.

Soya:
 * edamame
 * miso
 * natto
 * shoyu sauce
 * soya (soya albumin/lecithin, soya fiber, soya flour, soya grits, soya milk, soya nuts, soya sprouts)
 * soya (soy albumin/lecithin, soy fiber, soy flour, soy grits, soy milk, soy nuts, soy sprouts)
 * soyabean (curd, granules)
 * soyabean butter
 * soya protein (concentrate, isolate)
 * soya sauce, tamari
 * tempeh
 * textured vegetable protein (TVP)
 * tofu
 * E322 is sometimes derived from soya bean.
 * E476 is sometimes derived from soya bean.

Egg:
 * E322 can be derived from egg

Milk:
 * Lactose
 * Whey
 * Whey powder

Cookbook:Gluten-Free Flour

Various gluten free and wheat free flours are available. For people with celiac disease and no wheat allergy, gluten free flour is probably the best option as it is the most similar to normal flour. Gluten free flour is available in most supermarkets and can be obtained on prescription in some places if you have a diagnosis of celiac disease. Wheat free flours are a little more difficult to get hold of and can be harder to cook with but there are many different types available. Be aware that some wheat free flours still contain gluten, however wheat free and gluten free flours are available. Some of the most common wheat free flours are: potato flour, rice flour and soya flour.

Cookbook:Flapjacks

Flapjacks (UK) are a type of sweet bar dessert that can be made in less than an hour. They should not be confused with American flapjacks, which are a type of pancake or griddle cake. Also see the traditional Scottish recipe.

Ingredients

 * 150 g (6 oz) margarine
 * 75 g (3 oz) syrup
 * 75 g (3 oz) granulated sugar
 * 200 g (8 oz) quick rolled oats (not porridge oats)

Procedure

 * 1) Melt the margarine gently in a saucepan.
 * 2) Once the margarine has melted, add the syrup into the saucepan and stir well.
 * 3) Add the sugar into the saucepan and stir well.
 * 4) Add the quick rolled oats into the saucepan, and stir well until well mixed.
 * 5) Press the mixture into a well greased non-stick tin.
 * 6) Bake at 180°C (350°F) for 30 minutes (change as necessary for the oven).
 * 7) Leave to cool in the tin.

Notes, tips, and variations

 * Oats may be unsuitable for people with wheat allergy or celiac disease, because oats can be contaminated with wheat during processing. If cooking for someone with one of these conditions, be sure to look for oats that are specifically marked 'gluten-free' or 'wheat-free'.
 * To make this recipe suitable for people with milk or soya allergy use a dairy free, soya free margarine.

The Ten Commandments/Do Not Covet

You shall not covet is one of the Ten Commandments, which are widely understood as moral imperatives by legal scholars, Jewish scholars, Catholic scholars, and Post-Reformation scholars. The book of Exodus describes the Ten Commandments as being spoken by God to Moses, inscribed on two stone tablets by the finger of God, and later written on tablets by Moses. The full text of the commandment reads:

Unlike the other commandments which focus on outward actions, this commandment focuses on the human heart. It is an imperative against setting one’s desire on things that are forbidden. One commandment forbids the act of adultery. This commandment forbids the desire for adultery. One commandment forbids stealing. This commandment forbids the desire for unjust acquisition of another’s goods. The New Testament describes Jesus as interpreting the Ten Commandments as issues of the heart’s desires rather than merely prohibiting certain outward actions.

The command against coveting is seen as a natural consequence of the command to “love your neighbor as yourself.” The prohibition against desiring forbidden things is also seen as a moral imperative for the individual to exercise control over the thoughts of his mind and the desires of his heart.

Ancient usage
The Hebrew word translated “covet” is “chamad” which can be translated into English as “covet”, “lust”, and “strong desire.” The Hebrew Bible contains a number of warnings and examples of negative consequences for lusting or coveting. For example, when God was instructing Israel regarding the false religion of the Canaanites, he warned them not to covet the silver or gold on their idols, because this can lead to bringing detestable things into the home. The Book of Joshua contains a narrative in which Achan incurred the wrath of God by coveting prohibited gold and silver that he found in the destruction of Jericho. This is portrayed as a violation of covenant and a disgraceful thing.

The book of Proverbs warns against coveting, “Above all else, guard your heart, for it is the wellspring of life.” The prophet Micah condemns the coveting of houses and fields as a warning against lusting after physical possessions. The Hebrew word for “covet” can also be translated as “lust,” and the book of Proverbs warns against coveting in the form of sexual lust.

Jewish interpretation
Maimonides (the Rambam) viewed the prohibition of coveting as a fence or boundary intended to keep adherents a safe distance away from the very serious sins of theft, adultery, and murder.

Maimonides’ admonition to learn from the example of Ahab and Naboth refers to the narrative in 1 Kings 21 in which King Ahab of Israel tried to convince Naboth the Jezreelite to sell him the vineyard Naboth owned adjacent to the king’s palace. Ahab wanted the land to use as a vegetable garden, but Naboth refused to sell or trade the property to Ahab saying, “The LORD forbid that I should give up to you what I have inherited from my fathers!” Ahab’s wife Jezebel then conspired to obtain the vineyard by writing letters in Ahab’s name to the elders and nobles in Naboth’s town instructing them to have two scoundrels bear false witness claiming that Naboth has cursed both God and the king. After Naboth was subsequently stoned to death, Ahab seized possession of Naboth’s vineyard. The text describes the LORD as very angry with Ahab, and the prophet Elijah pronounces judgment on both Ahab and Jezebel.

Other Jewish views portray the prohibition of coveting as having its own fundamental and independent significance apart from the other nine commandments. For example, the Bava Batra teach that a person can even harm his neighbor with his eyes. It asserts that damage caused by looking is also regarded as damage that is prohibited. Even if the covetous desire is concealed in the heart, the covetous desire in itself is regarded by the Torah as damaging to the neighbor.

Philo describes covetous desire as a kind of revolution and plotting against others, because the passions of the soul are formidable. He regards desire as the worst kind of passion, but also one over which the individual exercises voluntary control. Therefore, near the conclusion of his discourse on the Decalogue, Philo exhorts the individual to make use of this commandment to cut off desire, the fountain of all iniquity. Left unchecked, covetous desire is the source of personal, interpersonal, and international strife.

Ibn Ezra taught that a person can control his desires by training his heart to be content with that God has allotted to him.

New Testament view
The Gospel of Luke describes Jesus' warning to guard one’s heart against covetousness. "Take care, and be on your guard against all covetousness, for one’s life does not consist in the abundance of his possessions." Jesus also describes the sins that defile a person as sins from coming from untamed desires in the heart. The book of James portrays covetous desire residing in the heart as being the internal source of temptation and sin. James goes on to describe how covetous desire leads to fighting and that lack of material possessions is caused by not asking God for them and by asking with wrong motives.

The books of Ephesians and Colossians regard the sin of covetousness as a kind if idolatry and list this sin along with sexual immorality and impurity which give rise to the wrath of God.

The New Testament stresses thanksgiving and contentment as proper heart attitudes that contrast covetousness. John the Baptist exhorted soldiers to be content with their pay rather than extorting money by threats and false accusations. The book of Hebrews encourages one to keep his life free from the love of money and “be content with what you have” and depend on the promises and help of God rather than trusting in wealth. The book of 1 Timothy contains a classic warning against the love of money and stresses that it is great gain to be content with food and clothing.

Teaching of the Roman Catholic Church
The Catholic Church considers the prohibition on coveting in Deuteronomy 5:21 and Exodus 20:17 to include two commandments, which are numbered the ninth and tenth commandments in Catholic teaching. In the Catholic view, the ninth commandment is a prohibition on carnal concupiscence (or lust), and the tenth commandment prohibits greed and the setting of one’s heart on material possessions.

Prohibition of carnal concupiscence (lust)
A key point in the Catholic understanding of the ninth commandment is Jesus’ statement, “Every one who looks at a woman lustfully has already committed adultery with her in his heart.” There is an emphasis on the thoughts and attitudes of the heart as well as the promise that the pure in heart will both see God and be like him.

While baptism confers upon the Christian purification of sins, the baptized must continue to struggle against disordered desires and the lust of the flesh. By God’s grace he can prevail 1) by virtue of the gift of chastity which empowers love with a undivided and upright heart 2) by purity of intention which seeks to find and fulfill the will of God in everything 3) by purity of vision which disciplines the feelings and imagination and refuses complicity with impure thoughts, and 4) by prayer which looks to God for help against temptation and casts one’s cares upon God.

Adherence to the ninth commandment’s requirement of purity requires modesty, which protects the intimate center of the person. Modesty refuses to unveil what should remain hidden. Modesty is a servant of chastity and guides how one looks at others and behaves toward them in protective conformity with the dignity of the human person. Modesty encourages patience and moderation in loving relationships, requiring that the conditions for the definitive giving and commitment of man and woman be fulfilled to one another. It is a decency that inspires one’s clothing. Modesty is discrete and avoids unhealthy curiosity.

In addition to personal purity and modesty, the Catholic Church teaches that Christian purity requires a purification of the social climate. Communications media ought to demonstrate respect and restraint in their presentations which should be free from widespread eroticism and the inclination to voyeurism and illusion. Moral permissiveness rests on a wrongheaded understanding of human freedom. Education in the moral law is necessary for the development of true freedom. Educators should be expected to give young people “instruction respectful of the truth, the qualities of the heart, and the moral and spiritual dignity of man.”

Prohibition of greed and envy of possessions
Catholic teaching on the prohibition of greed and envy center around Christ’s admonishments to desire and store up treasure in heaven rather than on earth, “For where your treasure is, there will your heart be also.” The tenth commandment is regarded as completing and unfolding the ninth. The tenth commandment forbids coveting the goods of another, as the root of the stealing and fraud forbidden by the commandment, “You shall not steal.” "Lust of the eyes" leads to the violence and injustice forbidden by the commandment, “You shall not murder.” Covetousness, like sexual immorality, originates in the idolatry prohibited by the first three commandments. The tenth commandment summarizes the entire law, by focusing on the intentions and desires of the heart. Covetous desires create disorder because they move beyond satisfying basic human needs and “exceed the limits of reason and drive us to covet unjustly what is not ours and belongs to another or is owed to him.” Greed and the desire to amass earthy goods without limit are forbidden. Avarice and passion for riches and power are forbidden. “You shall not covet” means that we should banish our desires for whatever does not belong to us. Never having enough money is regarded as a symptom of the love of money. Obedience to the tenth commandment requires that envy be banished from the human heart. Envy is a capital sin that includes sadness at the sight of another’s goods and the immoderate desire to acquire them for oneself. The baptized person should resist envy by practicing good will and rejoicing and praising God for material blessings granted to neighbor and brother. God warns man away from what seems "good for food . . . a delight to the eyes . . . to be desired to make one wise," and law and grace turn men’s hearts away from avarice and envy and toward the Holy Spirit who satisfies man’s heart. Catholic teaching reminds that Jesus enjoins his disciples to prefer him to everything and everyone, and bids them "renounce all that [they have]" for his sake and that of the Gospel. Jesus gave his disciples the example of the poor widow of Jerusalem who gave out of her poverty all that she had to live on. Detachment from riches is portrayed as obligatory for entrance into the Kingdom of heaven. "Blessed are the poor in spirit" represents the expectation that those who do not receive all their physical longings are more inclined to seek fulfillment of their spiritual longings through Jesus Christ. “The Lord grieves over the rich, because they find their consolation in the abundance of goods.” "I want to see God" expresses the true desire of man. The water of eternal life quenches the thirst for God. Attachment to the goods of this world are a bondage. The Scriptural remedy is the desire for true happiness that is found in seeking and finding God. Holy people must struggle, with grace from on high, to obtain the good things God promises. Christ’s faithful put to death their cravings and, with the grace of God, prevail over the seductions of pleasure and power. For what does it profit a man to gain the whole world, yet lose his own soul?

Reformation and Post-Reformation views
Martin Luther views sinful human nature such that no person naturally desires to see others with as much as oneself, each acquiring as much as he can while pretending to be pious. The human heart, Luther says, is deceitful, knowing how to adorn oneself finely while concealing one’s rascality.

Luther further explains that the tenth commandment is not intended for the rogues of the world, but for the pious, who wish to be praised and considered as honest and upright people, because they have not broken any of the outward commandments. Luther sees covetousness in the quarreling and wrangling in court over inheritances and real estate. He sees covetousness in financiering practiced in a manner to obtain houses, castles, and land through foreclosure. Likewise, Luther sees the tenth commandment as forbidding contrivances to take another man’s wife as one’s own and uses the example of King Herod taking his brother’s wife while his brother was still living.

John Calvin views the tenth commandment as a demand for purity of the heart, above and beyond the outward actions. Calvin distinguishes between making an explicit design to obtain what belongs to our neighbor and a covetous desire in the heart. For Calvin, design is a deliberate consent of the will, after passion has taken possession of the mind. Covetousness may exist without such a deliberate design, when the mind is stimulated and tickled by objects on which we set our affection.

In explaining the prohibition on covetousness, Calvin views the mind as either being filled with charitable thoughts toward one’s brother and neighbor, or being inclined toward covetous desires and designs. The mind wholly imbued with charity has no room for carnal desires. Calvin recognizes that all sorts of fancies rise up in the mind, and he exhorts the individual to exercise choice and discipline to shifting one’s thoughts away from fleshly desires and passions. Calvin asserts that God’s intention in the command is to prohibit every kind of perverse desire.

Matthew Henry sees the tenth commandment striking at the root of many sins by forbidding all desire that may yield injury to one’s neighbor. The language of discontent and envy are forbidden in the heart and mind. The appetites and desires of the corrupt nature are proscribed, and all are enjoined to see our face in the reflection of this law and to submit our hearts under the government of it.

Blender 3D: Noob to Pro/Creating Basic Water animation

Water and Other Fluids
Water is without a doubt one of the most important compounds in our lives; It covers about 75% of the earth and is therefore incredibly important in quite a few Blender animations. Wouldn't it be great if we could get an accurate physical representation of this liquid in Blender? We can, using a tool called Fluid Simulation. This tool looks unnervingly complex at first glance, but this tutorial should clear it up for you. At least to a basic level.

The Domain
One can imagine how much time it would take Blender3D to think about everything in the infinite space of a 3D world in terms of fluid objects and deflection, so we obviously need to cut down on that size. Create a fairly large cube. This will eventually be set as the volume in which all of the fluid simulation occurs. Don't make it too large, but not too small either, let's say 10 times bigger. With this cube selected, go to to the Physics context of the Properties window. Find the button that says "Fluid", and click the "Fluid" button to enable the function. Set type to "Domain". All the fluid physics will be calculated inside this cube. Also in that tab, you'll see 3 sub-sections, "Fluid World", "Fluid Boundary" and "Fluid Particles". Each one opens a different set of settings. These will be explained as they become important.

Under "Time" you can adjust how many seconds the fluid animation will take. Due to this you should change the "End" frame to "96", under the "Timeline", because the standard setting is "4". You can also change it how you like.

To make the other objects go into the "Wireframe" viewport.

The Fluid
As a basic start up for your experiments with fluid simulation, I am going to take you through a small demo in which we drop an object into a pool of water, creating a splash. To do this, we need a fluid object and an obstacle object. For the fluid, create another cube, scaled down to cover the bottom of your domain. Make a rectangle, that hovers just inside the domain and is half as high as the domain. Enable this object in fluid simulation also and set type to "fluid". When we start to bake the fluids, this will be set up as your liquid.

Let us go over what you have now. You have your starting cube, with fluid physics and type "domain", and will be referred to as "Domain". Inside this is the rectangle that will cover the bottom of your Domain, which is the liquid. The liquid will be a different object with the type "Fluid".

The Obstacle
Create a third object which we will call "Obstacle". This will be the object dropped into the water, and will be described further in the explanation. Give it an IPO/Animation to drop into the water, and enable it as --you guessed it-- an obstacle (click the "fluid" button, in physics, and set type to "obstacle").

Set up the animation in the front/side views, not the top view. The z-axis is where gravity works.

Baking Fluids
Now we get to see what it all looks like. Select the domain object, and find the big button that says "BAKE" under "Physics" - "Fluid". If you want to use a bake again, don't choose a temporary location, otherwise you'll have to bake it all over again. Press it. Be patient, blender has to bake this simulation, something like it would render the final product. The loading bar of this baking will stay in the bar at the top of the screen with the blender logo. If at any time you feel that you want to abort this process, press "Esc". Once the bake is finished, click under the "Timeline" on the play button. You should be able to view the full simulation.

Finishing touch
Blender will make your water its default opaque grey, unless you set its color. A good way to make realistic, clear water (as well as glass for that matter) is to edit the color, then apply a simple mirror effect plus transparency effect. After your water has rendered, select the domain in object mode. This selects the liquid in the frame you have just added. in the "Materials" tab (if when you click on this, the colors settings are not up, just press add new under the only panel there). Go to the "Mirror" section, play around with the settings until you get what you fancy. Suitable settings include Reflectivity to 0.1 for water, 0.15 for glass, set depth to 7; Under the Transparency section, click on Raytrace and set IOR to 1.3 for water, 1.5 for glass; Then set the Alpha value to 0.1 while adding an appropriate color under the "Diffuse" section, like: "6279E7". I should do the same for the "Fluid"

Other Fluid Objects
There are other incredibly useful types of fluid objects like "inflow" and "outflow". The both of these do exactly what they sound like. Inflow objects pour more fluid into the scene, and outflow objects drain it away.
