and your response:
Is there a way to know if my relationship is healthy? I have a friend who is in a relationship and they have been fighting lately. I think they are in a toxic relationship, but I don't know how to tell if mine is healthy.
|
It is important to understand that there is no "one size fits all" answer to your question. Every relationship is different, and there is no single way to define a "healthy" relationship.
That said, there are some general guidelines that you can use. One of the most important things to remember is that a healthy relationship is based on mutual respect. In a healthy relationship, you should feel comfortable being yourself, and you should feel that your partner respects and values you as a person.
Another important aspect of a healthy relationship is honesty. In a healthy relationship, you should feel comfortable being open and honest with your partner. Your partner should feel the same way towards you. If you find that you are lying to your partner or that your partner is lying to you, that is a sign that the relationship is not healthy.
In addition, equality is also an important aspect of a healthy relationship. In a healthy relationship, neither partner should feel that they are "superior" to the other, and neither should feel like they are "inferior". The relationship should be equal in every way.
Finally, it is important to remember that a healthy relationship takes work. You shouldn't expect a healthy relationship to be perfect. You will have arguments and disagreements just like any other couple, but how you deal with those disagreements is what makes the relationship healthy.
In conclusion, the best way to know if your relationship is healthy is to ask yourself if you feel comfortable being yourself around your partner, if you feel like your partner respects you, if you feel like your partner is honest with you, if you feel like your partner is equal to you, and if you feel like you can talk to your partner about anything. If you can answer yes to all of those questions, then your relationship is probably healthy.

I am interested in the performance of code that involves floating-point operations. I have written code that computes a vector sum and a vector difference. I have also written code that computes the sum and difference of two matrices. I am wondering if the first code is more efficient than the second code.
For the first code, I have a vector $v$ of length 2000 and two matrices $A$ and $B$ of size 2000 by 2000. I compute the sum of the matrices and the difference of the matrices by computing the sum and difference
|
Except for code which does a significant number of floating-point operations on data that are held in cache, most floating-point intensive code is performance limited by memory bandwidth and cache capacity rather than by flops.
$v$ and the products $Av$ and $Bv$ are all vectors of length 2000 (16K bytes in double precision), which will easily fit into a level 1 cache. The matrices $A$ and $B$ are 2000 by 2000 or about 32 megabytes in size. Your level 3 cache might be large enough to store one of these matrices if you've got a really good processor.
Computing $Av$ requires reading 32 megabytes (for $A$) in from memory, reading in 16K bytes (for $v$) storing intermediate results in the L1 cache and eventually writing 16K bytes out to memory. Multiplying $Bv$ takes the same amount of work. Adding the two intermediate results to get the final result requires a trivial amount of work. That's a total of roughly 64 megabytes of reads and an insignificant number of writes.
Computing $(A+B)$ requires reading 32 megabytes (for A) plus 32 megabytes (for B) from memory and writing 32 megabytes (for A+B) out. Then you have to do a single matrix-vector multiplication as above which involves reading 32 megabytes from memory (if you've got a big L3 cache, then perhaps this 32 megabytes is in that L3 cache.) That's a total of 96 megabytes of reads and 32 megabytes of writes.
Thus there's twice as much memory traffic involved in computing this as $(A+B)v$ instead of $Av+Bv$.
Note that if you have to do many of these multiplications with different vectors $v$ but the same $A$ and $B$, then it will become more efficient to compute $A+B$ once and reuse that matrix for the matrix-vector multiplications.

Can you please write a Python script that extracts the ten most populated cities in Germany from the free Maxmind World Cities database and displays the result in a console-readable format?
The database is available here:
[Maxmind World Cities](https://www.maxmind.com/en/data-products/world-cities)
The script should be platform independent.
|
Sure, please take a look at csvkit. It provides a set of tools that adhere to the UNIX philosophy (meaning they are small, simple, single-purposed and can be combined).
Here is an example that extracts the ten most populated cities in Germany from the free Maxmind World Cities database and displays the result in a console-readable format:
```$ csvgrep -e iso-8859-1 -c 1 -m "de" worldcitiespop | csvgrep -c 5 -r "\d+"
| csvsort -r -c 5 -l | csvcut -c 1,2,4,6 | head -n 11 | csvlook

Most children around age 2 or 3 are ready to begin using scissors. It's important for children to know how to be safe with scissors. Once they're ready, using scissors can be an excellent way for the child to build fine motor skills and patience.
## Prepare to teach
1. Try fine motor skill activities to prepare the child for using scissors. Children need to build fine motor skills before they're ready to use scissors. Here are some activities that can help build the child's skills, and help you know if the child is ready:
* Precision: Squeezing watercolor paint from an eyedropper onto paper, playing with finger puppets
*
* Bilateral coordination: Tearing up paper from the recycling bin
*
* Finger and hand strength: Spinning a top, punching holes with a hole punch, playing with squirt guns, using clothes pins
2. Evaluate the child's ability to follow directions. The child should be able to follow instructions like "stop" or "put it down, please." If a child isn't able to follow safety rules, then they shouldn't be given anything dangerous.
3. Choose the right pair of scissors. Safety scissors are ideal for young children. Choose right-handed or left-handed scissors based on your child's dominant hand.
4. Know that most kids are ready to use scissors around the age of 2 or 3. Many young children are able to use scissors.Talk to an occupational therapist if you think your child is struggling or has a disability that might delay their learning to use scissors. There are adaptive scissors for kids with disabilities, and special techniques to help kids who struggle with scissors. A delay isn't the end of the world. It just means things will happen a little differently.
## Teach how to use scissor
1. Let the child see you use a scissors. Show them how you do it, and let them watch.
2. Ask the child to point at the scissors. Have them look at the scissors and point at them.
3. Ask the child to open their hands. Let the child know that the scissors need to be open.
4. Ask the child to open the scissors. Let the child know that they need to open the scissors.
5. Ask the child to take the scissors in their hands. Let the child know that they need to take the scissors in their hands.
6. Ask the child to take the scissors to their mouth.

Above ground pools are a modern, easy-to-install alternative to traditional underground pools. If you want to blend your above ground pool in with the rest of your yard, decorating it is a great way to start. With a few natural and practical decorations, like plants or a pool chairs, you can make your above ground pool a stylish part of your backyard. For siding options, you can install a deck, concrete or wood paneling, or glass panels.
## Add natural decorations
1. Set up potted plants as botanical decorations. Adding potted plants around your above ground pool can help it blend in with the rest of your backyard. If you install a deck, position a few potted plants around the sides or around the bottom of the pool. You can also grow trees or shrubs around the above ground pool as a long-term alternative.
2. Add tiki torches to brighten up the area surrounding your pool. Tiki torches are a popular way to give your above ground pool an outdoorsy touch. Stake the tiki torches in the ground surrounding the pool at an even distance from each other, positioning them upright to prevent them from tilting. You can buy tiki torches online, from a garden center, or at many home improvement stores. String lights around the tiki torches for cheap and stylish lighting while swimming at night.
3. Use straw bales if you want a rustic siding. Straw bales can make a cheap, natural siding for above ground pools. Stack the straw bales around the sides to approximately halfway up the above ground pool's height to use as a decoration and partial step into the pool. You can buy straw bales from some agricultural supply stores or plant nurseries. To keep the straw out of the pool, do not stack the straw bales to the full height of the pool.
## Choose practical decorations
1. Set up a cover to use as shade. Put up an umbrella, trellis, or pergola over the pool during summer months or in hot, sunny climates. If you have any naturally shady areas in your yard, like a large tree, you can also hang a tarp from it over the pool to provide shade.
2. Install a deck. You can install a deck around the above ground pool to provide a natural siding. Decks are a popular way to give your above ground pool a natural look. If you want a cheap, easy deck, you can install a wooden deck that is around the same height as the pool. You can install a deck using pressure-treated lumber or composite lumber, which is more durable and easier to maintain.
3. Install a pool chairs. You can

Flipping someone off is a classic nonverbal signal for showing anger and frustration toward a person. You might "flip the bird" to someone who has cut you off, insulted you, or otherwise provoked your ire. At its simplest, flipping someone off is just pointedly displaying your middle finger in their direction. More advanced techniques take on an element of comedy or performance art. Remember: when you flip someone off, you are calling him or her out – so use with caution, or be prepared for the consequences!
## Basic flip-off move
1. Give someone the finger. There is a simple straightforwardness to the classic "flip-off." Turn the back of your fist toward someone, as though you are shaking a fist at them. Then, extend your middle finger. Hold the pose and look the person in the eye. This is a quick and easy way to get the point across. Wave your finger around for emphasis. Hold it out firmly and emphatically to make sure that you get the point across.
2. Try using both hands. For added effect, whip out the "double-finger" flip-off. Flip the person off with both middle fingers at the same to show them that you are unusually angry. Do "the X": cross your middle fingers into an "X," and then hold them against your chest facing the offender.
3. Switch fingers. For a somewhat more dynamic insult, flash your left and right middle fingers at the person in rapid succession. Alternately, keep both middle fingers extended and wave them around for emphasis.
## Discreet flip-off move
1. Act like you are itching your nose. Reach up to your face as though you are going to itch your nose or your face. Look in the direction of the person that you want to flip off. Then, use your middle finger to scratch your nose while staring pointedly. The person that you are flipping off might not notice this move. However, it might give other onlookers a laugh.
2. Flip the person off behind their back. You might feel a bit better simply by releasing your anger somehow, even if the person you are flipping off doesn't see it. Try flipping the person off from behind their back. Make sure that your middle finger is clearly visible to the person that you are flipping off.
## Comedic flip-off move
1. Try flipping the person off with your pinky finger. Use your pinky finger instead of your middle finger. This move is a bit more subtle and comedic than using the middle finger.
2. Use your middle finger to make a "V" for victory. Extend your middle finger with your other fingers cur

First, Mazur's paper is arguably the first paper where the new ideas (and language) of the Grothendieck revolution in algebraic geometry were fully embraced and crucially used in pure number theory. Here are several notable examples: Mazur makes crucial use of the theory of finite flat group schemes to understand the behavior of the $p$-adic Tate modules of Jacobians at the prime $p$. He studies modular forms of level one over finite rings (which need not lift to characteristic zero when the residue characteristic is $2$ or $3$). He proves theorems about mod-$p$ modular forms using what are essentially comparison theorems between etale cohomology and de Rham cohomology, and many more examples. The proof of the main theorem ($\S5$, starting at page 156) is itself a very modern proof which fundamentally uses the viewpoint of $X_0(N)$ as a scheme.
Second, there are many beautiful ideas which have their original in this paper: it contains many of the first innovative ideas for studying $2$-dimensional (and beyond) Galois representations, including the link between geometric properties (multiplicity one) and arithmetic properties, geometric conceptions for studying congruences between Galois representations, understanding the importance of the finite-flat property of group schemes, and the identification of the Gorenstein property. There is a theoretical $p$-descent on the Eisenstein quotient when previously descents were almost all explicit $2$-descents with specific equations. It introduces the winding quotient, and so on.
Third, while it is a dense paper, it is dense in the best possible way: many of the small diversions could have made interesting papers on their own. Indeed, even close readers of the paper today can find connections between Mazur's asides and cutting edge mathematics. When Mazur raises a question in the text, it is almost invariably very interesting. One particular (great) habit that Mazur has is thinking about various isomorphisms and by pinning down various canonical choices identifies refined invariants. To take a random example, consider his exploration of the Shimura subgroup at the end of section 11. He finishes with a question about a certain $p$-adic Hilbert modular form. Mazur then considers various isomorphisms between Shimura subgroups, and in doing so identifies the Hilbert modular form which he can then study.
Finally, Mazur was one of the first to recognize the importance of the geometric viewpoint, and his writing reflects this. The language he uses is the language of algebraic geometry, with some new ideas. For example, Mazur is the first to use the language of $p$-adic curves in this context, which is very important. The paper also contains many beautiful arguments,

Most people have heard of Down syndrome. But there are hundreds of other chromosome disorders a child can have, many of which are diagnosed in only a few children, or may even be unique to that child.
## Get information
1. Learn about genetics. Most people have 46 chromosomes, arranged in 23 pairs. One pair is the sex chromosomes, which in males is usually XY and in females XX. The other 22 pairs, known as autosomes, are numbered by size, with chromosome 1 being the biggest. Each chromosome has a longer arm, called the q arm, and a shorter arm, called the p arm. Each arm has bands that are numbered, with the band closest to the middle (centromere) being numbered 11.1. Terminus (shortened to "ter") refers to a tip of a chromosome. A "terminal" chromosome disorder is not fatal; it just involves the terminus. Learn about the types of changes. Nullisomy means that there are zero copies of a chromosome. Deletion/monosomy means that there is only one copy of the chromosome or piece of chromosome. Duplication/trisomy means that there are 3 copies. Tetrasomy and pentasomy refer to 4 and 5 copies, respectively. Translocations are when chromosomes swap material. If it is balanced, this means the same number of copies of material is present, but they are arranged differently - for example they have part of 3q on 2q and part of 2q on 3q, but it all adds up to the same thing. If it is unbalanced, the child has trisomy and/or monosomy for some part of the involved chromosomes. Very often, an unbalanced translocation is inherited from a parent with a balanced translocation, but it can also occur as a new mutation, which is called 'de novo'. For example, they may have part of 2q missing and part of 3q in its place, causing partial monosomy of 2q and partial trisomy of 3q.
### Get information
2. In a Down syndrome child, the chromosome is trisomic (has 3 copies), but the type of change is translocation. The long arm of chromosome 21 (q arm) is translocated to the short arm of chromosome 11 (p arm), causing the child to have 4 copies of part of 11, 3 copies of part of 21, and no copy of part of 11.

I need help with this line:
```cp /templates/apple /templates/used && cp /templates/apple /templates/inuse && rm /templates/apple```
What do you mean by:
```&&``` executes the right-hand command of ```&&``` only if the previous one succeeded.
```||``` executes the right-hand command of ```||``` only it the previous one failed.
```;``` executes the right-hand command of ```;``` always regardless whether the previous command succeeded or failed. Unless ```set -e``` was previously invoked, which causes ```bash``` to fail on
|
You are using ```|``` (pipe) to direct the output of a command into another command. What you are looking for is ```&&``` operator to execute the next command only if the previous one succeeded:
```cp /templates/apple /templates/used && cp /templates/apple /templates/inuse && rm /templates/apple
```
Or
```cp /templates/apple /templates/used && mv /templates/apple /templates/inuse
```
To summarize (non-exhaustively) bash's command operators/separators:
* ```|``` pipes (pipelines) the standard output (```stdout```) of one command into the standard input of another one. Note that ```stderr``` still goes into its default destination, whatever that happen to be.
* ```|&```pipes both ```stdout``` and ```stderr``` of one command into the standard input of another one. Very useful, available in bash version 4 and above.
* ```&&``` executes the right-hand command of ```&&``` only if the previous one succeeded.
* ```||``` executes the right-hand command of ```||``` only it the previous one failed.
* ```;``` executes the right-hand command of ```;``` always regardless whether the previous command succeeded or failed. Unless ```set -e``` was previously invoked, which causes ```bash``` to fail on an error.

Why are variable declarations in C similar to how they are used in expressions?
|
Dennis Ritchie’s paper on The Development of the C Language gives some idea of the reasoning behind this: namely, the fundamental rule in C that declaration syntax should match expression syntax"
For each object of such a composed type, there was already a way to mention the underlying object: index the array, call the function, use the indirection operator on the pointer. Analogical reasoning led to a declaration syntax for names mirroring that of the expression syntax in which the names typically appear. Thus,
```int i, *pi, **ppi;
```
declare an integer, a pointer to an integer, a pointer to a pointer to an integer. The syntax of these declarations reflects the observation that ```i```, ```*pi```, and ```**ppi``` all yield an ```int``` type when used in an expression. Similarly,
```int f(), *f(), (*f)();
```
declare a function returning an integer, a function returning a pointer to an integer, a pointer to a function returning an integer;
```int *api[10], (*pai)[10];
```
declare an array of pointers to integers, and a pointer to an array of integers. In all these cases the declaration of a variable resembles its usage in an expression whose type is the one named at the head of the declaration.
It appears this rule trumped parser considerations. Its immediate consequence is that function declarations can’t use specific keywords, or impose a different ordering of declaration components.
It’s worth noting that parsing was somewhat different in early C, since function declarations didn’t specify their arguments, and function definitions separated the argument list from the argument declarations (which weren’t necessary for ```int``` arguments):
```sum();
```
declares a ```sum``` function, which would then be defined as
```sum(a, b) {
return a + b;
}
```
(no types needed here, the default is ```int```). So the parser didn’t deal with types inside argument lists.

How can I connect to my mysql container from the outside of the container?
|
By default after deployment MySQL has following connection restrictions:
```mysql> select host, user from mysql.user;
+-----------+---------------+
| host | user |
+-----------+---------------+
| localhost | healthchecker |
| localhost | mysql.session |
| localhost | mysql.sys |
| localhost | root |
+-----------+---------------+
4 rows in set (0.00 sec)
```
Apparently, for the security purposes you will not be able to connect to it outside of the docker image.
If you need to change that to allow root to connect from any host (say, for development purposes), do:
* Start your mysql image with all port mappings required:
```docker run -p 3306:3306 --name=mysql57 -d mysql/mysql-server:5.7```
or, if the complete port mapping is required:
```docker run -p 3306:3306 -p 33060:33060 --name=mysql57 -d mysql/mysql-server:5.7
```
* If this is the fresh installation - grab the default password:
```docker logs mysql57 2>&1 | grep GENERATED```
* Connect using ```mysql``` client directly to the mysqld in docker:
```docker exec -it mysql57 mysql -uroot -p```
* If this is the fresh installation you will be asked to change the password using ```ALTER USER``` command. Do it.
* Run SQL:
```update mysql.user set host = '%' where user='root';```
* Quit the ```mysql``` client.
* Restart the container:
```docker restart mysql57```
Now you will be able to connect from MySQL Workbench to
```host: `0.0.0.0`
port: `3306`
```
After all the changes the query will show:
```select host, user from mysql.user;
+-----------+---------------+
| host | user |
+-----------+---------------+
| % | root |
| localhost | healthchecker |
| localhost | mysql.session |
| localhost | mysql.sys |
+-----------+---------------+
4 rows in set (0.00 sec)
```

Whether you need to touch up a scratch on your living room wall or your child wants their bedroom to be the exact same color as their favorite toy, it can be difficult to find a perfect match to an existing paint color. Luckily, there are plenty of tricks and tools that can help you find the color you’re looking from, including using paint samples, smartphone apps, and in-store computerized color matching!
## Match paint without a sample
1. Clean the area you're trying to paint match. Over time, fingerprints, dust, and dirt can collect on the surface of an object or a wall, and this can make the paint color seem darker than it actually is. To make sure you're testing the actual color, wipe the paint down with a damp, soapy sponge, and allow it to dry completely before you try to match the color. In addition to giving you a more accurate color match, cleaning the wall will help the new paint adhere better.
2. Scrape off a 1 in (2.5 cm) sample of drywall paint with a razor knife. If you’re trying to match paint on sheetrock or drywall, the easiest way to get a perfect match is to bring a sample with you to the paint store. Use a utility knife to score a square into the surface of the sheetrock about ⁄8 in (0.32 cm) deep, then peel away the paper. Place the sample in a plastic bag or an envelope so it doesn’t get smudged before you get to the paint store. Once the store has analyzed the color, dab a little of the paint onto a corner of the sample and let it dry to ensure it’s a perfect match.
3. Bring the item you’re matching to the paint store if it's portable. Thanks to the computerized color-matching technology at most paint stores, you can match almost anything! If you’re trying to find a paint that’s the same color as an object, you can bring that object in with you when you go to buy paint. The staff at the paint store will then scan the item and come up with an exact or near-exact color match.
## Match paint with a smartphone app
4. Download a color-matching app. A variety of smartphone apps can help you find an exact paint color match, even if you don’t have a sample of the paint. Many apps are free, and they allow you to take a picture of the object you’re trying to match and get a color match instantly. If you’re in a pinch, this is a great way to get a color match.
5. Get an exact match with a paint sample. If you’re painting a wall or another large surface, it

How do you avoid SQL injection attacks in a PHP web application that uses MySQL as a database?
### Context:
You are a PHP developer who has been tasked with creating a web application using PHP that uses MySQL as a database. You want to ensure that your application is secure against SQL injection attacks, but you are unsure of the best practices for doing so.
SQL injection attacks are a type of security vulnerability that can allow an attacker to inject malicious SQL commands into a database query, allowing them to access sensitive data or even take control of the database. To prevent these attacks, it is
|
The correct way to avoid SQL injection attacks, no matter which database you use, is to separate the data from SQL, so that data stays data and will never be interpreted as commands by the SQL parser. It is possible to create an SQL statement with correctly formatted data parts, but if you don't fully understand the details, you should always use prepared statements and parameterized queries. These are SQL statements that are sent to and parsed by the database server separately from any parameters. This way it is impossible for an attacker to inject malicious SQL.
You basically have two options to achieve this:
1. Using PDO (for any supported database driver):
```
$stmt = $pdo->prepare('SELECT * FROM employees WHERE name = :name');
$stmt->execute([ 'name' => $name ]);
foreach ($stmt as $row) {
// Do something with $row
}
```
2. Using MySQLi (for MySQL):
Since PHP 8.2+ we can make use of execute_query() which prepares, binds parameters, and executes SQL statement in one method:
```
$result = $dbConnection->execute_query('SELECT * FROM employees WHERE name = ?', [$name]);
while ($row = $result->fetch_assoc()) {
// Do something with $row
}
```
Up to PHP8.1:
```
$stmt = $dbConnection->prepare('SELECT * FROM employees WHERE name = ?');
$stmt->bind_param('s', $name); // 's' specifies the variable type => 'string'
$stmt->execute();
$result = $stmt->get_result();
while ($row = $result->fetch_assoc()) {
// Do something with $row
}
```
If you're connecting to a database other than MySQL, there is a driver-specific second option that you can refer to (for example, pg_prepare() and pg_execute() for PostgreSQL). PDO is the universal option.

The headline for this article reads:
NASA to pay $187,000 for ‘Planetary Protection Officer’ to defend Earth from aliens
I have read the article, and the first bullet point in the 'Highlights' section reads:
'Highlights' - protect Earth from aliens
It seems as though this person is getting paid to defend Earth from aliens. Is this a good use of taxpayer money?
Should the government be defending us from aliens?
|
You're observing shamefully bad journalism. The "protect Earth from aliens" bullet point in the "Highlights" section of the article was put there by an editor who either ignorantly or willfully distorted the actual role of the Planetary Protection Officer.
The first paragraph of the story gets a little closer:
The full-time role of "planetary protection officer" will involve ensuring that humans in space do not contaminate planets and moons, as well as ensuring that alien matter does not infect Earth.
"Planetary Protection Officer" isn't a new position; the current one is retiring. The primary focus of the planetary protection office is sterilizing probes that are going to other planets and moons. This is done both to preserve any existing life elsewhere in the solar system from Terran competition, and so that if and when we find life on other bodies, we will know we didn't bring it ourselves.
Preventing microbes from other worlds reaching Earth is also a concern, for similar reasons.
Developing and implementing the policies of the planetary protection office is a complex job requiring a broad array of both technical and human skills, and so a $187K salary is not remarkable for it:
Candidates will be required to travel frequently — but like any job, there will be a significant amount of emails, proposals and other reading.
Candidates must have at least one year's experience as a top-level civilian government employee, and an advanced degree in physical science, engineering or mathematics. They must also have "advanced knowledge" of planetary protection.
The position also requires "demonstrated skills in diplomacy that resulted in win-win solutions during extremely difficult and complex multilateral discussions". The new hire will also receive "secret" security clearance. Only US citizens and US nationals can apply.

Water towers are large, elevated tanks of water that are essential for the distribution of clean water to many communities across the globe. Not only do they come in many different shapes and sizes, but it’s intriguing to learn about the way water towers work. Whether you need a model water tower for a train set or school project, or you simply want to learn about the way they work, you can easily build your own model with the right materials and know-how.
## Create a function model water tower
1. Locate a small plastic bottle and a large plastic bottle. The small water bottle can be a standard-sized Coke, juice, or water bottle, as long as it has a screw-on cap. The large bottle should be a 2-liter soda bottle, jug, or a large juice bottle. Test the size of your bottles by placing the small bottle upside-down, with its neck sticking into the opening on the large bottle. The small bottle should sit comfortably on top of the large one. If it does not, you will need to find different bottles. The bottles must be plastic, as you will need to cut them.
2. Remove the cap from the small bottle and cut a hole in the middle of it. Use scissors to punch a hole into the center of the cap, then widen the hole until it’s slightly smaller than the circumference of the holes at both ends of the tubing. Water will leak out of the hole if it’s too big, but it will still need to be big enough to push the tubing into it. It’s better to have a hole that’s too small than a hole that’s too big, as you can always use your scissors to widen it if necessary.
3. Punch a pin-sized hole in the bottom of the small water bottle. Use a pin, needle, earring, or any other device that will create an almost invisible hole. This will allow the bottle to vent when the water starts flowing.
4. Cut a medium-sized hole in the side of the large bottle. Make the hole big enough to fit the tubing through. This will allow the water to flow from the large bottle to the small bottle.
5. Cut a small hole in the side of the large bottle. Use your scissors to cut a small hole in the side of the large bottle, big enough to slip the tubing through. This will allow the water to flow back into the large bottle when the water tank is full.
6. Stretch the tubing between the bottles. Slip the tubing through the hole in the side of the large bottle, then through the hole in the

Are there any gases that can diffuse through metal? If so, can you describe the process of
|
Yes, some gases can diffuse into and through metal. It is the bane of the high-vacuum engineer's life. Hydrogen is the worst because it tends to dissociate into atoms at the surface and the nucleus, a single proton, can then leave its electron behind and wander through the metal lattice until it picks up another electron when it leaves.
For example Mu-metal, favoured for some applications, typically has to be annealed in hydrogen at high temperature. Once that is over, it can take weeks or months for the residual hydrogen to diffuse out of the metal before a high enough vacuum can be achieved and the work proceed.
A "virtual leak" occurs where a small bubble of gas is embedded in the material inside a vacuum chamber. The leak usually happens because a tiny hole exists for the gas to diffuse out through, but sometimes the "hole" is no more than an ultra-thin skin of metal (invisible to the frustrated technician) and the gas diffuses through it. These little horrors can keep going for months or even years and generally mean replacing suspected parts and pumping down over and over again until the dodgy one is finally stumbled on.
Helium is both monatomic and the physically smallest atom. It can diffuse more easily than any other neutral atom or molecule, making certain metal foils unsuitable as say gas-tight liners for airships. As noted in another answer, in quantity it can also affect the bulk properties of the metal.
On a more energetic scale, hydrogen and helium nuclei (protons and alpha particles) can pass through thin metal foils if fired with sufficient energy, and this has been used to establish the crystalline structures of some metals and alloys (where, for whatever reason, electrons were unsuitable).
Other gases have much larger atoms (neon and other noble gases) or molecules (nitrogen and other diatomic molecules, water and other hydrides), but they can still diffuse extremely slowly through some metals. This can limit the lifetime of some microchips. A "dead" chip (one with no power supply and no way to test it) may appear to be fine for months or even years, but eventually, the internal gases will diffuse through the metal layers, and they will leak out. The leak can then be detected by measuring the internal pressure. This is why a chip manufacturer will typically keep a sample of every batch of chips, and periodically test the pressure, in case any are leaking.

This is a rather complex math problem, and a few more steps would be needed to get a definitive answer. But the overall logic is sound and I like the idea of using rarity to prove that the claim is wrong. The IQ comparison site has some great information.
|
This claim can actually be tested very easily. Others have done it, e.g. Brian Dickerson: The perils of repeating political nonsense and came to the conclusion that the claim was wrong.
You just need the chance a random person from a large group has a genius level IQ, then multiply it with the number of people in China and compare the result with the number of people in the USA. The IQ follows a Gaussian distribution where 100 is the mean by definition and a standard deviation (SD) of 15 (after Wechsler) or 16 (after Stanford-Binet). The rarity of a particular IQ can be calculated easily and are listed by the IQ Comparison Site. These numbers give the percentage of people with an IQ equal or lower than the given IQ and the rarity of this occurring.
The main question actually is what an genius level IQ is. There is no definite answer. According to the IQ Comparison Site, it is 140 or higher ("Genius or near genius") while another source states it as at least 160.
The rarity of such an IQ is 1/261 (with a SD of 15) or 1/161 (SD=16) for an IQ of 140 and 1/31,560 (SD=15) or 1/11,307 (SD=16) for an IQ of 160 according to Wikipedia.
The population of USA for 2012 is about 313,221,000 according to the U.S. Census Bureau. The population of China for 2011 is about 1,370,537,000.
Taking the lowest rarity of 1/161 from above then there are about 1,370,537,000/161 = about 8,513,000 geniuses in China, which is significantly less then the 313,221,000 Americans.
If you take the higher rarity of 1/261 then there are about 8,513,000 geniuses in China and about 313,221,000 geniuses in USA.
It can be concluded that the claim is false.

## View your sample
1. Hold a UV light up to the gel sheet to reveal results. With your gel sheet in front of you, find the switch on a tube of UV light to turn it on. Hold the UV light 8–16 inches (20–41 cm) away from the gel sheet. illuminate the DNA samples with the UV light to activate the gel and read the results. If the test was performed properly, your sheet should have 2-8 sets of vertical stripes in parallel rows.Warning: Wear gloves and protective eyewear when physically handling a gel sample. Touching the gel can interfere with your results and some of the gels are harmful if they get in your eyes. Place the gel sheet on a piece of wax paper if you’re removing it from the machine. The individual stripes indicate specific strands of DNA. The strips should have varying levels of thickness. If you’re reading results that have been printed on a sheet of paper, you can skip this step.
2. Find the wells by looking for the biggest pools of color. To properly orient yourself, you need to find the original location of the samples, called the wells. With your sheet in front of you, look for the end of the sheet with a big pool of colored gel. The wells are the locations where the gel samples are loaded into the sheet and indicate the start of the sample.There should be one well for each of your samples. If one of the wells is lacking color, the sample may have been applied poorly. The wells indicate the negative end of the sheet. The opposite side of the sheet is the positive end. When each sample is applied to the sheet, the negatively-charged DNA travels across the sheet to the opposite side, leaving individual samples of DNA behind as it moves.
3. Classify each strip by noting the origin of the samples. If you’ve been given a key, understand that each horizontal row depicts a unique set of DNA. Use your key to determine what each row represents. The number of samples can be determined by counting the number of rows. If you haven’t been given a key, you cannot determine the source of each sample, but you can determine if there are enough samples to complete the experiment.The number of samples can be determined by counting the number of rows.
4. Read the samples by noting the location of the stripes. The stripes indicate the presence of specific DNA. They are typically a darker color than the rest of the sheet. The stripes can be used to determine the type of DNA in each sample. The number of stripes in each sample indicates the number of DNA sequences. If you’re reading results that have been printed on a sheet of paper, you can skip this step.

Why do some women go up a shoe size during pregnancy?
|
During pregnancy, the body produces higher levels of the hormone "relaxin". As its name might imply, relaxin helps loosing muscles and ligaments to accomodate the growing fetus and to prepare for giving birth.
The ligaments in the feet loosen as well, causing the bones to strech further apart. This effect is amplified by the added pregnancy weight, causing some women to go up a full shoe size during pregnancy.

The Prague Uprising of 1848 (Czech: Pražské červnové povstání), also known as the Pentecostal Storm, was an armed conflict on 12-17 June 1848 in Prague, which culminated in the revolutionary process in the Czech lands. The uprising was a spontaneous unprepared uprising, which was suppressed by the army and killed about 43 people.
##Background
From March 11, 1848 (Assembly in Svatováclavské lázně) there was a political unrest in Prague, by which Prague joined the wider revolutionary current in the whole of Europe. At that time, Czech politics had already split into a liberal current (František Palacký, Karel Havlíček Borovský) and a radically democratic one (Karel Sabina, Josef Václav Frič, Vincenc Vávra Haštalský, Vilém Gauč, Emanuel Arnold). In the first phase, the moderate liberals prevailed. They preferred constructive and cautious steps, such as the establishment of the St. Wenceslas Committee on March 12. On 19 and 31 March, the Committee prepared two petitions to the Emperor, which mainly included the requirements of linguistic equality, the establishment of the National Newspaper (April 5), the transformation of the St. Wenceslas Committee into the National Committee (April 10), Palacký's Writing in Frankfurt (April 11), founding of the Lípa slovanská association (April 30), organization of the Slavic Congress (June 2-12). Meanwhile, the radical wing also strengthened. On June 1, its press body, the Prague Evening Paper, began publishing. It was then supported by the arrival of some delegates to the Slavic Congress (especially Mikhail Bakunin).
At the beginning of June, the commanding general in Bohemia, Alfred Windischgrätz, decided that the growing tensions would be dampened by military demonstrations of the garrison in Prague. The radical press of the Prague Evening Paper and the radical wing of the National Committee began to publish an aggressive tone, and on June 4, the National Committee decided to take up arms. The radicals, however, considered this decision too moderate. They called for an uprising in the streets, which was supported by the radical wing of the National Committee.
On June 5, the revolutionary process began in Prague. In the evening, 600-700 men, mostly workers, set out from the Konečná (

What is the equilibrium constant for combustion of organic matter in air with oxygen? Is it small or extremely large? Why?
### Clarification:
Can you provide some information about why combustion of organic matter in air with oxygen is extremely large? How do you know that the reaction is extremely large? Is it because the reaction is extremely exothermic?
Why can life exist in an oxygen atmosphere? Is it because the combustion of organic matter in air with oxygen is extremely large, or is it for some other reason? How does Life figure out
|
The equilibrium constant for combustion of organic matter in air with oxygen is not small, but extremely large ($K_\mathrm{eq} \gg 1$), as is expected from a reaction that is simultaneously very exothermic and (usually) increases entropy due to the formation of more gaseous molecules than the input oxygen.
The major reason carbon-based life can exist at ambient temperature in an oxygen atmosphere is purely kinetic, not thermodynamic. You, the tree outside and everything else made of carbon is right now undergoing continuous combustion. However, in the absence of catalyst, this process is too slow below a couple hundred degrees Celsius for it to be self-sustaining. More technically, combustion of organic matter is a highly exergonic process, but the activation energy is high. The meagre amount of heat generated by the handful of molecules reacting is too quickly diluted into the surroundings, and the reaction does not accelerate and spiral out of control (a fire, as described by the eternal Feynman).
Very luckily for us, Life figured out this vast untapped source of chemical energy held back by kinetics approximately three billion years ago and developed a whole metabolic process to extract this energy in a stepwise fashion using catalysis, which we call aerobic respiration. Without it, multicellular organisms could well never had evolved.

How can I do this in python:
```
x = {'a': 1, 'b': 2}
y = {'b': 10, 'c': 11}
z = dict(list(x.items()) + list(y.items()))
```
So the final dict in ```z``` will have ```x```'s values for the keys ```a``` and ```b``` and ```y```'s values for the keys ```c``` and ```b```.
### HINT:
In python, dicts are created with a single
|
Here is what you can do for the case you described:
```
z = dict(list(x.items()) + list(y.items()))
```
This will, as you want it, put the final dict in ```z```, and make the value for key ```b``` be properly overridden by the second (```y```) dict's value:
```>>> x = {'a': 1, 'b': 2}
>>> y = {'b': 10, 'c': 11}
>>> z = dict(list(x.items()) + list(y.items()))
>>> z
{'a': 1, 'c': 11, 'b': 10}
```
If you use Python 2, you can even remove the ```list()``` calls. To create z:
```>>> z = dict(x.items() + y.items())
>>> z
{'a': 1, 'c': 11, 'b': 10}
```
If you use Python version 3.9.0a4 or greater, you can directly use:
```>>> x = {'a': 1, 'b': 2}
>>> y = {'b': 10, 'c': 11}
>>> z = x | y
>>> z
{'a': 1, 'c': 11, 'b': 10}
```

What is the difference between having economic growth and protecting the environment? Aren't these two things mutually exclusive?
|
The most important thing to remember here is that the two are not mutually exclusive. It is possible to have economic growth while also protecting the environment, and in fact in many cases it is necessary.
For example, pollution control is often seen as an impediment to growth, but in many cases it actually leads to it. Consider the Clean Air Act in the United States. When it was passed in 1970, many predicted that it would cripple the economy. In reality, while it did cause some short-term economic pain (as any transition does), in the long term the economy grew substantially, and the cost of compliance with the act was actually less than predicted. This is because a cleaner environment leads to a healthier population, which is more productive. It also leads to less sickness, which reduces healthcare costs.
Similarly, investment in renewable energy has been a huge driver of economic growth in many countries. And it creates more jobs than fossil fuel energy production.
So in most cases, protecting the environment and promoting economic growth go hand-in-hand. You can't have long-term economic growth without a healthy environment, because without a healthy environment, the economy will eventually collapse.

Why do raymarching and sphere tracing belong to the same family?
|
## TL;DR
They belong to the same family of solvers, where sphere tracing is one method of ray marching, which is the family name.
## Raymarching a definition
Raymarching is a technique a bit like traditional raytracing where the surface function is not easy to solve (or impossible without numeric iterative methods). In raytracing you just look up the ray intersection, whereas in ray marching you march forward (or back and forth) until you find the intersection, have enough samples or whatever it is your trying to solve. Try to think of it like a newton-raphson method for surface finding, or summing for integrating a varying function.
This can be useful if you:
* Need to render volumetrics that arenot uniform
* Rendering implicit functions, fractals
* Rendering other kinds of parametric surfaces where intersection is not known ahead of time, like paralax mapping
etc.
## Sphere tracing
Sphere tracing is one possible Ray marching algorithm. Not all raymarching uses benefit form this method, as they can not be converted into this kind of scheme.
Sphere tracing is used for rendering implicit surfaces. Implicit surfaces are formed at some level of a continuous function. In essence solving the equation
```F(X,Y,Z) = 0
```
Because of how this function can be solved at each point, one can go ahead and estimate the biggest possible sphere that can fit the current march step (or if not exactly reasonably safely). You then know that next march distance is at least this big. This way you can have adaptive ray marching steps speeding up the process.

Write a story about how a writer was planning to publish a novel.
He was sure he had all the necessary safety measures in place.
But then, when he was just about to publish, his novel was stolen and self-published.
It was all a prank by a cybercriminal.
The cybercriminal was the writer's friend.
He knew that the writer had safety measures in place to keep his novel safe, and had hacked into the writer's PC to steal it and publish it.
The cybercriminal was confident that

He titled his first two works “Rough Draft”.
This time he called it “Completed Draft”.
He let his friend in on the plan when they met up face-to-face.
Firstly, he sent her fake text messages outlining how this time he was "very confident" he knew how to keep his works safe on his PC from ‘hackers’.
He sent a text stating that he would create a handwritten draft that would be fully edited, which he would then type up on his computer in a few hours on the 25th of May and publish quickly within 24 hours.
It was a win-win situation.
He knew that if the hacker wasn't watching his texts, he would be able to publish his novel.
But if they were, they'd be caught out.
His completed draft was stolen on 25th of May and self-published to Amazon before he had the chance to do so himself.
He erased all traces of the draft on his computer.
Just to make sure, the hard-drive was destroyed as well.
He knew the cyber thief wouldn’t be able to completely check and edit the story within the short timeframe.
So, on page 198 of his light-hearted fantasy novel, he decided to abruptly interrupt the story to detail “intelligence leaks and tips” in Arabic to “potential terrorists” from a “professional criminal hacker/high-level government employee”, (his two best guesses as to who had repeatedly hacked his computer).
He sent an anonymous tip to the FBI.
They decided to check if the original publisher really was a high-level government employee.

I'm interested in the topic of handedness and wanted to know more about it. Can you tell me about handedness and how it affects people? How common is it for people to be left handed? Are there any environmental factors that influence handedness? Are there any genetic factors that influence handedness? Is it common for a child's handedness to change over time?
|
Handedness is a very interesting phenomenon, but it is not as simple as being either left or right handed.
In most people the brain is asymmetrical, with some functions, such as language, being localised to one hemisphere. In most people this is the left hemisphere, which leads to these people being right handed as they use their dominant hand to perform tasks involving fine motor control, such as writing. Left handed people have their language centres in the right hemisphere, and while they may perform other tasks with their left hand they can often do tasks involving fine motor control with either hand.
There are also people who are truly ambidextrous, capable of performing tasks with either hand equally well. These people, while rare, do not have brains that are symmetrical, but have developed connections between the two hemispheres that allow them to access both motor cortices.
The genetics of handedness are complex and not well understood. There does appear to be a genetic component, but it is not straightforward. Identical twins who are brought up in the same environment are not always both left or right handed, suggesting that environmental factors also play a role.
One of the most interesting things about handedness is how early it becomes apparent. Children as young as two years old can be assessed for handedness, and it is very rare for a child's handedness to change over time. This suggests that it is very strongly influenced by genetics, with environmental factors playing a minor role.

## Plan and prepare for the trip
1. Plan to visit between June and August. Since snow and ice usually cover the cave temple, you won’t be able to access it during the cold winter and spring months. Wait until mid-June or July to plan your trip to the Amarnath Temple. Usually, the cave stays open through the first 1–2 weeks of August before it closes due to the terrain getting too difficult for travel. The actual dates when you can travel to the temple are chosen by the Shri Amarnathji Shrine Board (SASB) and it varies depending on the weather and how clear the trails are. You will not be able to reach the Amarnath Temple at any other time of the year.
2. Get a Compulsory Health Certificate by a doctor approved by the SASB. Look at the list of approved doctors on the SASB website and schedule an appointment to see one. Bring the Compulsory Health Certificate from the site with you and fill out the self-assessment on top. Allow your doctor to run any tests to check if you’re fit for traveling to the Amarnath Temple. If they approve you for traveling, then you’ll be able to make the journey.You can find the Compulsory Health Certificate for 2020 here: http://www.shriamarnathjishrine.com/Yatra2019/CHC%20form%20for%20Yatra%20-%202020.pdf. The certificate you need changes each year, so make sure you’re using the proper one. Since the Amarnath Temple is 4,000 metres (2.5 mi) above sea level, it’s possible to get altitude sickness if you aren’t fit enough for the trip.Warning: You will not be allowed to go to Amarnath Temple if you are under 13, over 75, or more than 6 weeks pregnant.
3. Submit a registration form online to the SASB. Select the date you want to travel to the temple on the calendar at the top of the page. Fill out the personal details on the registration form and upload a passport-sized photo of yourself. Submit the form with the payment for the fee, which is currently INR 4,500.00 for Indian citizens and INR 9,000.00 for foreigners. The registration form is in English, Hindi, and Kashmiri.You can find the registration form for 2020 here: http://www.shriamarnathjishrine.com/Yatra2019/Yatra%20Registration%20form%20-%202

## Play the concentration game
1. Create game pieces. Make small cards using paper or something sturdier such as cardstock. Cut small squares out and be sure to make each piece the same size. Since this is a memory game, it is important that each card looks the same so you are unable to differentiate one card from the next.
2. Write out information on game pieces. Work in pairs when writing out your review information on these cards. Write down a vocabulary word on the first card in the pair and its definition on the second. Continue writing on your cards until each review item has been covered. This game words best when reviewing things like definitions, spelling, examples, etc.
3. Organize your cards. Flip over all your cards so that the writing is underneath. Place your cards face down and organize them into rows and columns until every game piece is situated.
4. Flip over one card. Begin the game by choosing just one card to turn over. Read the definition or vocabulary word and choose one more card to turn over. If you flipped over the correct card, you should have a pair in which both cards are a match. When first starting out, this game is sheer luck, but after a few tries you will be able to remember where each card lies and can do your best to find its correct match.
5. Set aside pairs. When you have found two cards that are a match, set that pair aside so that your game board becomes smaller. Continue playing until every card has been turned over and you have created matches for each game piece. When you are finished playing, you can simply shuffle your cards and redistribute them to create your game board and play again.
## Play with card
1. Obtain a deck of cards. The first thing you need to do is get an entire deck of cards. Be sure you aren’t missing any because it will affect how you play the game.
2. Create a list of review items. Using your study materials, create a list of items you want to review. This list must be numbered and can be anything from definitions to vocabulary.
3. Pull out face cards from your deck. You want to eliminate any face cards from your deck. The reason for this is that you do not want to be able to differentiate between a card and its number. Since this game is a memory game, you need to be able to remember each card so it is easier to remember if it is in your list of items to review.
4. Organize your deck. Pull out your list and organize your deck so that each number is in its corresponding column. For example, if you have 20 items to review, you should have 20 cards. If you have more cards than items to review, simply use the face cards as your number

Given the following array
```
$arr = [
'foo' => 'bar',
'bar' => 'foo'
];
```
How would you retrieve the first key and value in PHP?
|
PHP
If you don't know enough about the array (you're not sure whether the first key is foo or bar) then the array might well also be, maybe, empty.
So it would be best to check, especially if there is the chance that the returned value might be the boolean FALSE:
```$value = empty($arr) ? $default : reset($arr);
```
The above code uses ```reset``` and so has side effects (it resets the internal pointer of the array), so you might prefer using ```array_slice``` to quickly access a copy of the first element of the array:
```$value = $default;
foreach(array_slice($arr, 0, 1) as $value);
```
Assuming you want to get both the key and the value separately, you need to add the fourth parameter to ```array_slice```:
```foreach(array_slice($arr, 0, 1, true) as $key => $value);
```
To get the first item as a pair (```key => value```):
```$item = array_slice($arr, 0, 1, true);
```
Simple modification to get the last item, key and value separately:
```foreach(array_slice($arr, -1, 1, true) as $key => $value);
```
performance
If the array is not really big, you don't actually need ```array_slice``` and can rather get a copy of the whole keys array, then get the first item:
```$key = count($arr) ? array_keys($arr)[0] : null;
```
If you have a very big array, though, the call to ```array_keys``` will require significant time and memory more than ```array_slice``` (both functions walk the array, but the latter terminates as soon as it has gathered the required number of items - which is one).
A notable exception is when you have the first key which points to a very large and convoluted object. In that case ```array_slice``` will duplicate that first large object, while ```array_keys``` will only grab the keys.
PHP 7.3+
PHP 7.3 onwards introduced ```array_first``` and ```array_last``` which are exactly what you need, if you don't need the key:
```$item = array_first($arr);```

Tell me about your first day as a barista in a cafe that caters to non-human customers. Include your feelings and emotions.
|
I had expected a worse first day.
Some of them are amicable, others decidedly less so.
There is, however, one thing that lingers in my mind. Human or beast, they all have one thing in common. Though I have seen a vast array of colours, a kaleidoscope of vivid green, crimson red and amber, they all seem to stare into my soul. Their eyes, piercing and penetrating bore into me, into the dark abyss that is my soul. I can't help but feel a sense of wonder, mingled with the dread of chaos and anarchy and destruction.
Some of them are noble. They have a profound look of sorrow on their faces that mirrors my own expression, and ignites a spark, a fire that rages below the surface of my apathetic existence.
I call for the next customer, and he approaches my desk. He lays a gnarled claw next to my hand, and begins to whisper; a low growl, barely audible, and yet I hear him as though he is screaming. He wants a piece of my soul, and a vial of my blood. He pays with fire.
He is no more a monster than I am.
Soon, it will be over, and I will be allowed to rest.

Write a short story that begins with the following sentence: "It was the day of Judgement, and the little town was found wanting."
The town of Blueberry Creek was a quaint little place, nestled in the foothills of the Blue Ridge Mountains. It was a tight-knit community, with families that had been there for generations. But on this day, the town was found wanting.
The volcano that had been dormant for centuries had suddenly erupted, spewing lava down the slopes. The townspeople had tried to fight back,
|
It was the day of Judgement, and the little town was found wanting.
Lava inexorably flowed down the volcano's rocky slope, a maelstrom of red and orange that could not be stopped. Everyone stared in wonder, and they knew in their hearts it was only a matter of time before the little town was completely engulfed. The first home to be swept away was a two story Colonial with blue shutters, painstakingly crafted. It was not just a mere house; it was a home. But lava does not care who you are and what you love. It's only concern is the conquest, and soon the house was no more, an ashen relic of a more stable time.
One by one, the houses of the little town were systematically eradicated, and it was inevitable that they would never be rebuilt. Distant onlookers gazed at destruction with rapt interest, not lifting a finger to help. They were not here to do mercy's work, and there was even a smattering of applause as the town became no more. There were no screams, no cries for help, no frantic pleas to God.
Ms. Hayworth told me it was the best model volcano she'd ever seen.

How do I keep my plants alive indoors?
I recently bought a few house plants and the soil was not very healthy. I have a small balcony, but it is very shaded. I live in an apartment and my
|
Indoor gardening is a bit more difficult then the regular outdoor gardening, there are several factors but in most cases it boils down to: Temperature, Humidity, Light, The air in your apartment.
You didn't mention exactly where your dying plants are being placed. Do you have a fan within the apartment? Plants need air whether it is natural or even if it is coming from a fan. What type of lighting is inside the apartment? Are you only using natural light? These are important factors to aide the growth of the plant as well. How is the temperature within the apartment? If you notice a lot of temp ups / downs in the area you are gardening than it is probably worth moving the garden or choosing another spot. With apartments that becomes all the more difficult.
Your plant also probably came from some nice greenhouse, an english gardens, a ray weigands, etc etc...They have plenty of light, they also have plenty of means of water and the temperature well most of this is all outside, so they have the advantage of using mother nature. Your plant needs to adjust to these conditions. You should try to begin to place your plants in a very lit area with as much natural wind / fan as possible, these plants need to breath. If your plants are not conditioned for this type of environment you run the risk that they give up and die.
When potting the plant ensure the actual pot is cleaned up to remove any unnecessary plant diseases from prior plants. Look on the bottom of the actual pot, are you getting drainage? If not drill a hole in the bottom of the pot if you can, if not toss that pot out and get you a pot that has a good amount of drainage. Overwatering plants will destroy them, and without nature (wind, temperature, etc) the water sitting there takes all the longer to dry out.
When it comes to veggies Tomatoes need a ton of sunlight and humidity is great for them as well. Herbs are probably the simpliest to get going but I'm not sure if this is what you are after. Cucumbers and squash don't need as much light. If you have a sunny window you can put these in as well. When it comes to herbs try to choose those that are more common. Dill, Basil, Parsley, Mint, Cilantro, Rosemary, Sage, Oregano, etc.

There is a window of opportunity for a launch to occur, known as a launch window. This certainly occurs when trying to get somewhere such as the International Space Station, but even earth orbiting satellites have a window of time where the rocket can meet its performance.
Bottom line is, the exact time of launch is very important, and a complex sequence of events have to happen in just the right order to make it happen. SpaceFlightNow provided a generic countdown timeline for the Falcon 9, I'll re-post a few of the highlights. Some of these things are done to keep the batteries topped off till the last minute. You don't want to put the fuel in until the last minute, to save it (Most rocket fuel is cryogenic). When the rocket has its fuel loaded, you want to keep non-essential personnel away from it, making it so any tasks they need to do is put off until the end. You don't want to arm the system to launch until you are completely ready, thus, it only happens right before. There are many more such examples of why things are done in a particular order, but hopefully this will give you a sense.

A short story, 100 words or less, about a child and their mother. The child's best friend is a teddy bear. The teddy bear's left eye has been cut out. The child is upset. Their mother tells them that they will fix it up together. What happens next?
|
Sammy didn't understand. Who would do such a thing?
The left eye of his best friend lay on the carpet floor in front of him. The shredded strands that once held it in place trailed behind, tattered and crimson.
All he could do was cry. He was the best friend anyone could want. A soul both soft and understanding. How could this happen? Sammy's mind was a mess of confusion and questions.
His mother entered the room, dragging the carcass.
"Now, now, Sammy. Everything going is to be okay."
Sammy spied something shiny and sharp in her hand.
Mommy smiled.
"Hand me his eye, sweetheart."
Sammy froze.
"We'll fix your teddy right up...together."

What is the best place to put the submit button in a form or dialogue?
|
Where to put the submit button should be decided in order to meet user expectations, it was best to put the button in the place that users expect to find it in the context of the form or dialogue they are using and with regard to the window size.
Forms tend to be left justified while the browser window can leave a ton of white space to fill up a large monitor (especially in full-screen mode). Since the users' eyes never leave the left portion of the window, we place the button on the bottom left. This is especially important for forms that use the field name above the field, with most fields lying flush left on the form (as opposed to fields to the right of their names).
Small Dialogue & Modal Windows are fixed width and tend to be small. Most contain simple phrases or questions, read right to left: having a button on the bottom right feels like both the most progressive position and the final resting place for the eye. Were the modal window large enough to contain a long form, we would probably follow the first principal for forms.
In the end, the heuristic is this:
* Large Windows & Forms get the button on the bottom left.
* Small Windows & Dialogues get the button on the bottom right.
Note the buttons on stackexchange sites:
* Post Your Answer button at the bottom-left of the longer form
* Add Comment button to the right of a small field
Furthermore, with mobile-first responsive being the new law of the land, the button placement varies even more based on context and user expectation. Sometimes, it's in the middle, too!
We're now starting to just put buttons on the left for even small forms if they're inline … and more forms are showing up inline through javascript.

If you had an unlimited amount of time, what would you do with it?
### Input:
I can spend my life never sleeping.
|
If I could spend my life never sleeping, some of the things I might do with that extra time include:
* Spend more time with friends and family. I can use the extra time to develop stronger ties and bonds with my loved ones, including my family members and close friends. I might watch films more often with them or host games at night that we can play together. Or, I might organize more potluck parties where each one bring a dish.
* Enjoy my favorite hobbies more (or discover new ones). I could use the extra time to take dance and music lessons, read more fiction books, collect action figures, etc. In addition, I would love to develop some new hobbies that I have always wanted to try, e.g. skiing and bouldering.
* Travel and see more of the world. If I had lots of extra time, I would use them to travel around the world to experience life in different ways. I could explore new places, cultures, cuisines, traditions, and ways of living. I can also make friends with people from different backgrounds.
* Exercise and improve my physical condition. With more extra time, I would become more active and commit to a healtier lifestyle. For example, I'll stick to a regular fitness plan and increase my physical activity by adding strength training and taking a Yogo class.
* Work more to advance my career and personal growth. I might use the extra time to learn new skills outside of my primary career. For example, I would learn a new language or pursue a part-time job in art history or education. Moreover, I would get out of my comfort zone and become more proactive in buidling my network.
* Get more involved in my community. With all of the extra time available to me, I could devote myself to volunteering or giving back to my local community. This might involve working with organizations like soup kitchens, animal shelters, or environmental conservation groups. Alternatively, I might consider starting my own nonprofit organization focused on addressing issues that matter most to me.

In a chess game, if I make an illegal move, what happens?
### Context:
This question is for a casual chess game played over the internet.
|
This only really applies to over the board games (since online chess servers prevent illegal moves).
In a standard time control game, under USCF rules, when the illegal move is noticed by one of the players, a few things happen. First, the illegal move must have been made within the last 10 moves. If not, then the current position stands, and play continues. Assuming that the move is recent, the position is restored to the position immediately before the illegal move.
Then, the player that made the illegal move now must make a legal move with the same piece (if one exists). If there are no legal moves, then the player is free to make any move. This is due to the touch move rule. Finally, if the offending player has pressed the clock, a two minute "bonus" is added to the opponent's clock to compensate them for any time lost and to penalize the offending player.
Here is the relevant passage from the USCF rulebook:
11A. Illegal move during last ten moves. If, during a game, it is found that one of either player's last ten moves was illegal, the position shall be reinstated to what it was before the illegal move. The game shall then continue by applying Rule 10, The Touched Piece, to the move replacing the illegal move. If the position cannot be reinstated, then the illegal move shall stand. Move counters on clocks that have them may by readjusted.
11D. Illegal move. If, a player completes an illegal move by pressing the clock, in addition to the usual obligation to make a legal move with the touched piece if possible, the standard penalty specified in rule 1C2a applies (i.e. two minutes added to the opponent's clock).
In blitz chess, the rules are different. According to the WBCA (World Blitz Chess Association) rules, a player who makes an illegal move loses the game instantly. This rule is frequently enforced in casual games too. The most common way that this occurs is that one player doesn't notice that they are in check and makes a move that doesn't check the opposing player. In this situation, it is often acceptable to ask the offending player to resign instead of playing on in a game that is effectively lost. If the offending player insists on playing on, then the only option is to inform the arbiter and play is stopped while the arbiter resolves the issue.

Write a story of a man named George who has a series of short stories. He's a prolific writer who has written many stories. The catch is that he has a hard time finishing his stories. He's gotten to the end of one story, but he can't figure out how to finish it. Write the next part of the story that describes what happens next.
|
George shot up in bed like a bolt of lightning. At long last he knew how to end his series. He excitedly explained to the young prostitute he had purchased at the Lord Baelish's pleasure house.
"Oh me, Lord.... you are such a clever man" she twirled a lock of her golden hair and looked at the large and sweet man with a curious look in her eyes
George stood up and pulled up his robe and carefully fashioned the turtle emblem to the front of his black attire."I don't know... it just came to me all of a sudden... I have the best ideas when I'm half asl-" The small yet quick handed girl had opened his throat and he fell face first into the Dornish sausage and spoiled a goblet of his favorite summer wine.....A sweet bread roll also fell to the ground. She headed to his room in the Red Keep to complete his story for him.

What are some little things you can do to save energy while renting a place?
|
There are a lot of little things you can do that can add up. Here are some suggestions:
* Wash clothes in cold water only.
* Turn your freezer/refrigerator up a few degrees.
* Purchase insulated curtains/shades, and close them during the day when you are at work.
* Make sure your furniture is arranged so that it is not blocking any vents or radiators.
* Purchase a draft guard to place at the bottom of your door leading to the outside where temperature-controlled air can escape from your apartment.
* Install a low flow shower water head. Shower head screw on/off easily. Keep the old head to replace when/if you move.
* Clean Your Refrigerator: It's unlikely that you'll purchase new energy efficient appliances for your rental, but you can tweak the ones you already have. For example, by cleaning the coils on the back of your fridge you'll help one of the biggest energy hogging appliances run more efficiently.
* Use Energy Efficient Bulbs, even if you're put off by the slightly higher upfront cost, you can simply unscrew them and take them with you when it's time to move.
* Use Power Strips: A lot of energy is wasted through electronics left plugged in, and the resulting vampire energy. Put a stop to it by using one of a number of cool, smart energy strips, which will turn off vampire energy when the electronics are not in use.
* Use a Humidifier & Lower Your Heat: Keeping humidity levels up during the winter is not only good for your health, but also for your air and furniture. It also helps keep the ambient air temperature feeling warmer than dry air, which means you can turn your thermostat down. If your HVAC system doesn't have a humidifier built-in, then you can get an inexpensive and portable humidifier to use during dry conditions.

If you have a history of heart problems or related disease, call emergency services (911 in the US) immediately. Do not try to drive yourself to the hospital. Before the ambulance comes, here are a few things you could do:
* Take a deep breath and count to 3. This will help relax you and slow your heart rate.
* Lie down in a comfortable position.
* Loosen your clothing, particularly your shirt. This will allow your heart to cool.
* Take an over-the-counter aspirin tablet, unless you are allergic to aspirin or have been told by your doctor not to take it. This can help thin blood and prevent clots from forming.
* Monitor your pulse. If you feel your pulse getting faster or slower, this is a sign your heart is in trouble. Tell the paramedics when they arrive.

The three-body problem is one of the most famous problems in the history of mathematics, which also has an important application in science: it was supposed to explain the Moon's motion, among other things. Enormous effort was spent on this problem by many famous mathematicians of the 18th and 19th centuries. Since Newton's time it was clear that there was no simple closed form solution. (The problem also had an important practical application in 18th century, namely to navigation. If you can predict the motion of the Moon for few years ahead with sufficient accuracy, you can determine longitude at sea without a chronometer, just by observing Moon's position with respect to the stars).
In the middle of the 19th century, an exact mathematical formulation of what was desired was achieved: to express the motions of the bodies in the form of convergent series of functions of time, valid for all times. Few people remember nowadays that in this precise form the problem was actually solved (by Sundman, at the very end of the 19th century). This solution can be found in Siegel's book on celestial mechanics.
But by that time it was already understood that this solution was useless for practical purposes, namely for prediction of the Moon's motion over long time periods. It was also useless for understanding the qualitative features of the motion.

By definition, nothing's going to happen in an empty room (though see below). There are no hidden doors to find, no puzzles to solve, no enemies to fight. So what's their purpose?
## Bringing the dungeon to life
While all the orcs may sit around in a guard room waiting for PCs to show up, where do they sleep, what do they eat, what happens to their trash? Think of a dungeon not just as a place to have fights in, but as an actual place that serves a purpose. Once you do, the dungeon will start making sense. "Empty" rooms will increase immersion for the players, and force you to consider things you may not have otherwise. Should there be a pet otyugh that eats the trash? Are the orcs demanding cows from the local farmers for "protection"? Do they keep a famed halfling cook enslaved, to make them rare steaks?
## Foreshadowing
Once the dungeon makes sense, you can use that to place clues for things that dwell deeper within. Has a horde of zombies marched through to guard the necromancer's abode within, and left a few rotten body parts here and there? Has a malevolent force been summoned and spoiled all the meat and milk in the dungeon? Is there a golem maintenance station, with oil to grease them, rags to polish them, and a mad goblin mechanic? These may be vital clues PCs need to prepare for a tough fight, or they can simply let them form theories and feel smart about being right once they do come upon a golem or three.
#Currently empty
These rooms are empty now, but they don't have to stay that way. PCs may choose to fortify a room and bring the enemy to them - such tactical choices could be an important part of dungeoncrawling. Orcs may chase PCs through the dungeon, or randomly come across them in a kitchen because they were feeling peckish.
Note that some of these ideas would introduce creatures you haven't yet placed, which could throw off your planning. However, some creatures may only appear once per adventure, and you can save them for a future adventure.
## Tactical fights
The orcs aren't there to fight you. They're just there to keep the dungeon safe. They're also the dungeon's defenders, and it makes no sense for them to be hanging out in the hallways and not in the guard rooms. However, there may be a few orcs on guard duty. They are the bosses of

Where is the Ark of the Covenant in Indiana Jones and the Last Crusade?
|
There was a deleted scene that explained it:
A plot element involving the Ark of the Covenant was cut from the film and is only hinted at during the finale when the Ark is opened.
Basically, there were 2 rules about the Ark not mentioned in the final cut of the film:
* If you touch the Ark, you die
* If you look at the Ark when it is opened, you die
This is first explained in additional dialogue for the scene when Indy and Sallah visit Imam. Before translating the writings on the headpiece that give the height of the Staff of Ra, Imam warns Indy not to touch the Ark or look at it when it is opened.
[Source]
The next scene involving this Ark subplot is when Sallah and Indy remove the Ark from the Well of the Souls. When Sallah first sees it he reaches out to touch it. Indy stops him before he does and reminds him of Imam's warning. Then they insert long poles through each side of the Ark to lift it out of its crypt.
[Source]
Notice that nobody ever touches the Ark throughout the rest of the film until the finale.
And from the Bible (King James Version):
1 Samuel 6:19:
And he smote the men of Bethshemesh, because they had looked into the ark of the Lord, even he smote of the people fifty thousand and threescore and ten men...
2 Samuel 6:6-7
And when they came to Nachon's threshingfloor, Uzzah put forth his hand to the ark of God, and took hold of it; for the oxen shook it. And the anger of the Lord was kindled against Uzzah; and God smote him there for his error; and there he died by the ark of God.

Can I start an auction at $1000 when I only have $1000 in cash?
I'm playing monopoly.
### Context:
I'm playing Monopoly.
### Task:
Explain why this is allowed.
### Task:
Explain why this is not allowed.
|
This is definitely allowed, and a good tactic to leverage a cash advantage.
There is no minimum or maximum price for an auction. The rules state:
Bidding may start at any price.
Monopoly auctions do not have "the bidding will start at $10". They just have "bidding is open". Once the auction begins, a bid by any player sets the minimum price for the auction at that bid. Your opponent could easily bid $10 on the property, forcing you to either let them have it for $10 or bid more than you have in cash. You could bid first, say starting the bid at $5, but that doesn't meaningfully change the situation, as they can just respond by out-bidding you at $10.
You may bid more money than you have in cash, but you are still obligated to pay it if you win the auction. This may be a reasonable play if you can afford it by mortgaging property and/or selling houses, especially to drive up the price for your opponent. But be careful not to bid more than you can pay after mortgages and sales, as if you win the auction and can't pay your bid, you go bankrupt. In particular, if you bid more than you can afford, you opponents can all just let you win the bid, at which point you go bankrupt and the property you just bought would go up for auction again (in addition to all your other properties).

Which genes are "turned on" when performing a complex musical piece? Why are they turned on?
|
Based on a 2015 article from Nature Scientific Reports, many genes are "turned on" when performing a complex musical piece.
These genes are related to muscle control, neural flexibility and growth, and even to the pleasure center in the brain.
Interestingly, variants of about a third of these genes were also previously identified as relating to song production and perception in songbirds.

Fuzzy String Matching is the process of performing a human-like estimation of the similarity of two words or phrases. In many cases, it involves implementing the Levenshtein distance algorithm, which determines how many changes must be made to a string or phrase to turn it into another string or phrase. The following implementation in VBA involves a weighted comparison of the length of the two phrases, the number of changes between each phrase, and whether each word could be found in the target entry.
```
'Calculate the Levenshtein Distance between two strings (the number of insertions,
'deletions, and substitutions needed to transform the first string into the second)
Public Function LevenshteinDistance(ByRef S1 As String, ByVal S2 As String) As Long
Dim L1 As Long, L2 As Long, D() As Long 'Length of input strings and distance matrix
Dim i As Long, j As Long, cost As Long 'loop counters and cost of substitution for current letter
Dim cI As Long, cD As Long, cS As Long 'cost of next Insertion, Deletion and Substitution

* Is there a way to make a ImageView keep the original image aspect ratio when scaling the image?
* How can I use the imageView.setBackground() to keep the original image ratio?
* How can I use the imageView.setBackground() to scale the image to the view?
* How can I make the ImageView scale to the image, instead of the image scale to the view?
* How can I tell Android to not scale the image when loading it into the ImageView?
* How can I tell Android to scale the image to the ImageView?
### Context:
|
* Yes, by default Android will scale your image down to fit the ImageView, maintaining the aspect ratio. However, make sure you're setting the image to the ImageView using ```android:src="..."``` rather than ```android:background="..."```. ```src=``` makes it scale the image maintaining aspect ratio, but ```background=``` makes it scale and distort the image to make it fit exactly to the size of the ImageView. (You can use a background and a source at the same time though, which can be useful for things like displaying a frame around the main image, using just one ImageView.)
* You should also see ```android:adjustViewBounds``` to make the ImageView resize itself to fit the rescaled image. For example, if you have a rectangular image in what would normally be a square ImageView, adjustViewBounds=true will make it resize the ImageView to be rectangular as well. This then affects how other Views are laid out around the ImageView.
Then as Samuh wrote, you can change the way it default scales images using the ```android:scaleType``` parameter.
By the way, the easiest way to discover how this works would simply have been to experiment a bit yourself! Just remember to look at the layouts in the emulator itself (or an actual phone) as the preview in Eclipse is usually wrong.

How do I get started investing?
|
First off, I highly recommend the book Get a Financial Life. The basics of personal finance and money management are pretty straightforward, and this book does a great job with it. It is very light reading, and it really geared for the young person starting their career.
Now, with that out of the way, there's really two kinds of "investing" to think about:
1. Retirement (401k, IRA, SIMPLE, etc)
2. Non-Retirement (Brokerage account, investing in individual stocks, day trading, etc)
For most individuals, it is best to take care of #1 first. Most people shouldn't even think about #2 until they have fully funded their retirement accounts, established an emergency fund, and gotten their debt under control.
There are lots of financial incentives for retirement investing, both from your employer, and the government. All the more reason to take care of #1 before #2!
Your employer probably offers some kind of 401k (or equivalent, like a 403b) with a company-provided match. This is a potential 100% return on your investment after the vesting period. No investment you make on your own will ever match that. Additionally, there are tax advantages to contributing to the 401k. (The money you contribute doesn't count as taxable income.)
***The best way to start investing is to learn about your employer's retirement plan, and contribute enough to fully utilize the employer matching.***
Beyond this, there are also Individual Retirement Accounts (IRAs) you can open to contribute money to on your own. You should open one of these and start contributing, but only after you have fully utilized the employer matching with the 401k. The IRA won't give you that 100% ROI that the 401k will.
Keep in mind that retirement investments are pretty much "walled off" from your day-to-day financial life. Money that goes into a 401k or IRA doesn't count as taxable income, and you can't withdraw it early without incurring a penalty. However, if you have some money left over, it is generally a good idea to put it in a brokerage account to invest in the stock market.

What is an appropriate word to use in place of "overdominant" in the following sentence:
"There are many religions in the world. However, only a few religions are overdominant."
I want to make the sentence sound like a dictionary definition. I want to avoid the use of the word "overpowered", because it implies that the other religions are weak. I want to avoid the use of the word "preponderant", because I don't know how to pronounce it.
|
There is the term "overdominant":
From Collins dictionary:
>overdominant [adjective]
excessively dominant
To begin with, the design aspect is the most striking and arguably remains overdominant. [Times, Sunday Times (2010)]
Here is an example:
> [Steps must be taken to prevent any one] religious or ethnic group being overdominant. Otherwise, we will see a repeat of the unfortunate history of much of the 20th Century...
Other possible terms that have similar meaning include "overpowered", "obtrusive" and "preponderant".

I want to create an app that helps people to order pizza together in a large group. How could I do that?
|
Ordering a pizza in a large group can be tricky, especially if there are varying preferences and dietary constraints. To address this problem, here is a proposal of an automatic pizza ordering app named AutoSlice. AutoSlice is installed on each user's phone, and contains each user's manually configured preferences (e.g. toppings, number of slices, allergies, etc.), which can be adapted in real time when ordering. One user (the host) starts an order and invite the other users to join. The app also uses location services to find nearby pizzerias from which to build a recommended order. Once the order is confirmed, the host can then distribute the bill automatically to each user, or decide to pay for everyone.

Does this sentence make sense? "If you never intend to use your objects in hash tables (or anything else that relies on the rules of GetHashCode), your implementation doesn't need to follow the guidelines."
If not, what is missing? If so, is it a valid rule or guideline?
|
The answer is mostly, it is a valid guideline, but perhaps not a valid rule. It also doesn't tell the whole story.
The point being made is that for mutable types, you cannot base the hash code on the mutable data because two equal objects must return the same hash code and the hash code has to be valid for the lifetime of the object. If the hash code changes, you end up with an object that gets lost in a hashed collection because it no longer lives in the correct hash bin.
For example, object A returns hash of 1. So, it goes in bin 1 of the hash table. Then you change object A such that it returns a hash of 2. When a hash table goes looking for it, it looks in bin 2 and can't find it - the object is orphaned in bin 1. This is why the hash code must not change for the lifetime of the object, and just one reason why writing GetHashCode implementations is a pain in the butt.
A guideline is just a guide, not a rule. In reality, ```GetHashCode``` only has to follow these guidelines when things expect the object to follow the guidelines, such as when it is being stored in a hash table. If you never intend to use your objects in hash tables (or anything else that relies on the rules of ```GetHashCode```), your implementation doesn't need to follow the guidelines. When you see "for the lifetime of the object", you should read "for the time the object needs to co-operate with hash tables" or similar. Like most things, ```GetHashCode``` is about knowing when to break the rules.

Write a poem about a time you felt sad and how you felt after you took a break.

It takes a while to climb this mountain. Your feelings like a fountain, your flow strained.
The darkness rampant, it pulls you into a hole. While your goal is to climb ever higher.
You can fight it off, but it keeps you drained. You feel weak and framed.
The sadness looms, you feel so tired. But suddenly you are wired and sprinting up a mountain side.
Self preservation is lost, you embitter. People fear and flitter away as your mania grows stronger.
Now you've reached the top and feel like jumping. Without hesitation your heart pumping, you take that step.
You fall far, deeper then you ever have before. Your heart is scored deep and bloody.
When you think this is all over it can begin again. Your life is a blackened campaign.

What is the most common issue with IoT devices? How can I avoid them?
### Context:
I'm an IoT enthusiast and I'm looking for ways to improve the security of my devices. What are some simple things I can do to protect my IoT devices?
|
The absolute most common issue with IoT devices is default passwords. So change all the passwords. Pick a unique, random password for every device and write it down on paper (paper is safe from remote attackers and hard drive failures). 12 random (i.e. computer-generated) lowercase letters represent a good compromise between security and being hard to type. Each device should have a different password so that breaking one doesn't let the attacker break all of them. Enter the passwords in a password manager and use that password manager in the computers you use to control the devices.
If the device has different authorization channels, for example an administration password and a day-to-day usage password, use different passwords for both and only record the administration password on selected devices.
The second generic security measure is to ensure that all your devices are behind a firewall or at least a NAT device. A typical home router is sufficient, but you should turn off UPnP which can allow inadvertent back channels from the outside. The goal is to ensures that there's no direct way to connect from the Internet to the device. Connections should always go through a gateway that itself requires authentication to cross, and that you keep patched with any security updates.
You should also apply security updates on all the device if they exist at all, which can be a problem.

Cowboy hats have a long tradition, both for functional purposes while working and as a fashion statement. Even if it seems as simple as setting the hat on your head and going about your business, there are some rules to follow if you want to wear a cowboy hat properly. You need to get a hat that fits right, shape it a little bit, make sure the front is forward, and angle to give your look the proper attitude.
## Choose your hat
1. Get the right size. The first step to properly wearing a cowboy hat is making sure the hat is the right size and fits your head properly. Cowboy hats should typically fit snug around your head. If you are buying one, know your hat size ahead of time but also try the hat on before you buy it.
2. Fix your current hat to fit better. You may have a hat already that is just barely too big but not big enough that you would want to get a smaller size. You can fix this. You can buy foam strip that is specifically made to put into hats to make them fit tighter. Depending on how much you need, and the shape of your head, you can either put this foam all the way around, or you can put a little in the front and back, just on the sides, or even just the front or just the back. Figure out where your hat is fitting too loosely. If the whole hat is sitting too low on your head, you probably want to put some sizing foam around the whole hat. There should be a band around the inside of the hat that you can flip up and place the foam strip under. Then flip the band back down before wearing the hat.
3. Pick the right hat. You have a lot of options when it comes to cowboy hats. The main material choices are felt (made of beaver or rabbit pelt), leather, and straw. Felt hats are warmer so they tend to be worn more in the cold seasons. Straw hats are better for staying cool during hot days.
4. Shape your hat. Most cowboy hats can be conformed to a certain shape by gently bending and squeezing them. How exactly you do this will depend on what kind of hat you have, but you should be able to shape it a little bit without breaking the material. This is good for hats that fit too loosely. It's also a good idea to make sure the brim (the edge of the hat) is facing forward, and the side of the hat is facing to the side, so it gives the hat an overall more natural look.
5. Know the hat styles. There are several different styles of cowboy hats, so if you're looking for a particular style you should have some idea what that is. The most popular

, How can I scale my UI to large font sizes?
For the Ubuntu desktop there are some ways to scale your UI to large font sizes.
1. System wide Menu and titlebar scaling
Starting with Ubuntu 14.04 we have an option that helps a bit:
```LANG=c unity-control-center
```
Go to "Displays" and set the "Scale for menu and title bars".
2. Universal Access
Go to "Universal Access" (```unity-control-center universal-access```) and select "Large Text".
Note:
|
There are some steps to take:
1. System wide Menu and titlebar scaling
Starting with Ubuntu 14.04 we have an option that helps a bit:
Scaling Support
open the System Settings (here in english:)
```LANG=c unity-control-center
```
Go to "Displays" and set the "Scale for menu and title bars".
Since Ubuntu 17.10 the scaling can be set in
```LANG=c gnome-control-center
```
Go to ```Settings > Devices > Displays``` there
see also: How to find and change the screen DPI?
2. Universal Access
Go to "Universal Access" (```unity-control-center universal-access```) and select "Large Text".
Note: not all applications handle this correctly, some will not reserve the extra space, so some UI elements are not accessible with this option!
3.Increase unity dock size
In ```unity-control-center```->```Appearance```->```Look``` at the botom, you can adjust the size.
4. Adapt Firefox
see: Adjust Firefox and Thunderbird to a High DPI touchscreen display (retina)
(or use Chrome, which works fine since Version 41.0.2272.76 Ubuntu 14.10, though Chrome will need to be restarted to take effect)
5. Increase font in Pidgin
There is a plugin you can install:
```sudo apt-get install pidgin-extprefs
```
Then you can increase the font in Plugins->Extended Prefs
6. Create starter for applications that still don't scale
Some applications still don't obey the global scaling (mainly java) for those few applications you can create a starter to only Fix scaling of java-based applications for a high DPI screen
Note: In older Ubuntu versions, with unity-tweak-util in the section "Fonts" you can set the "Text Scaling Factor" to 2.0. This will scale the fonts in most applications to double size.

In general, employers in the United States are free to fire you for your speech. The First Amendment does not apply to anyone except the government (other than a narrow set of circumstances where private parties act on behalf of the government or take on government roles, like when private universities employ campus police). If the officer was being fired from a job at a private company, this would not be an interesting question -- the answer would clearly be "no, there is no First Amendment claim here." That’s not to say labor laws might not come into play (for instance, federal law prohibits firing an employee for organizing a union, and some states prohibit firing for off-duty political speech); however, labor law protections exist by statute and are not derived from the First Amendment.
What makes this interesting is that the government is involved. Unlike private employers, government agencies are bound by the First Amendment. In Pickering v. Board of Education, the Supreme Court held that this does restrict them in their role as employer and that they can't necessarily fire an employee for speech. Pickering imposes a balancing test, where the harm to the employee's First Amendment rights is weighed against the government's interest in efficient operation. Courts have given particular leeway to police departments punishing speech that would undermine public trust and confidence in the department. A police officer expressing racist views, even privately, can seriously hamper the effectiveness of the department if the speech gets linked back to them. For instance, see Pappas v. Giuliani, where the Second Circuit upheld the firing of an NYPD officer for anonymously mailing racist diatribes from home in his off-duty time.
Another answer suggests that the main question is a public safety one: whether the officer could be trusted to carry out his duties without bias. But that's not the only legitimate consideration for the government employer. The courts have repeatedly held that public perception of an agency is a legitimate concern, especially when it comes to agencies (like the police) whose job requires maintaining good relations with the community. In Pappas, the officer was assigned as a computer operator and not a patrol officer. The court held that this was not enough to overcome the risk of harm to the NYPD's reputation and trust with the public.

Here is the abstract and introduction of a research proposal about controlling biases and unwanted behaviors in large language models:
#Controlling Biases in Large Language Models
##Abstract
While large language models are unlocking previously unimaginable applications, their extensive usage also exacerbates the risk of generating toxic text that amplifies adverse biases in the training data. We propose utilizing the newfound instruction understanding abilities of large language models to identify, explain, and mitigate undesirable biases in text. Our research plan begins with a novel method for eliciting natural language explanations of why a particular text is harmful, without any training data or definition of what constitutes toxic text. We then propose to investigate whether explicitly instructing models to avoid biases using natural language prompts can steer them away from unwanted outputs. Finally, we aim to explore a more permanent solution by fine-tuning the model on anti-harm instructions (behavioral guidelines, codes of conduct, diversity training), and thus informing it on which utterances should be avoided. Successfully tuning large language models to better align with acceptable behavior will dramatically advance the ability to deploy safer, fairer models in real-world settings.
##Introduction
Language models, the cornerstone of modern natural language processing (NLP), are known to reflect and even amplify biases in training corpora, often resulting in racist, sexist, and generally toxic outputs. Susceptibility to such harmful biases hinders the deployment of these models and limits their applicability.
A common approach for developing safer models is to try to control the training corpora. [Citations], for example, used a list of banned words to filter potentially harmful text from the C4 corpus. This simple approach fails to remove all adverse biases from the text, as toxic content can be written using words that are, by themselves, benign. Another technique for corpus intervention is data augmentation [Citations], which adds a counterfactual example for each utterance of a potentially biased text. This technique, however, only applies when counterfactual swaps are possible, e.g. gender, race, or location.
In this work, we aim to use the newly unlocked ability of large language models to understand instructions and control their own behavior. Specifically, we propose to use the model's language understanding abilities to identify harmful biases in text and to elicit natural language explanations as to why the text is harmful. We then aim to use these explanations to fine-tune the model on anti-harm instructions, such as codes of conduct and diversity training.
In this way, we hope to control the behavior of large language models and steer them away from harmful

I'm trying to get ffmpeg to save a gif from a flv. I tried the command line:
```ffmpeg -i input.flv -vf scale=320:-1 -r 10 -f image2pipe -vcodec ppm - | convert -delay 10 -loop 0 - output.gif```
I've read that you can use the -layers Optimize command in ImageMagick, but I can't seem to get it to work with ffmpeg. Can you tell me how I can optimize the output to produce
|
If you would prefer to avoid intermediate image files, the commands provided by LordNeckBeard can be piped between ```ffmpeg``` and ImageMagick's ```convert``` so that no intermediate files are required:
```ffmpeg -i input.flv -vf scale=320:-1 -r 10 -f image2pipe -vcodec ppm - | convert -delay 10 -loop 0 - output.gif
```
The ```-f image2pipe``` tells ffmpeg to split the video into images and make it suitable to be piped out, and ```-vcodec ppm``` specifies the output format to be ppm (for some reason if the format is png, either ```convert``` does not read all the images from the pipe, or ffmpeg does not output them all). The ```-``` for both commands specifies that a pipe will be used for output and input respectively.
To optimize the result without saving a file, you can pipe the output from ```convert``` to a second ```convert``` command:
```ffmpeg -i input.flv -vf scale=320:-1 -r 10 -f image2pipe -vcodec ppm - | convert -delay 10 -loop 0 - gif:- | convert -layers Optimize - output.gif
```
The ```gif:-``` tells ```convert``` to pipe its output as gif formatted data and ```-layers Optimize``` tells the second ```convert``` to perform ```optimize-frame``` and ```optimize-transparancy``` methods (see the ImageMagick Introduction to Animation Optimization). Note that the output from the ```-layers Optimize``` may not always provide a smaller file size, so you may want to try converting to a gif without optimization first to be sure.
Remember that during this whole process everything is in memory so you may need sufficient memory if the images are quite large.

How to delete all symbolic links in the current directory?
|
Please make sure to read the alternative answer. It's even more to the point although not voted as high at this point.
You can use this to delete all symbolic links:
```find -type l -delete
```
with modern ```find``` versions.
On older find versions it may have to be:
```find -type l -exec rm {} \;
# or
find -type l -exec unlink {} \;
```
To limit to a certain link target, assuming none of the paths contain any newline character:
``` find -type l | while IFS= read -r lnkname; do if [ "$(readlink '$lnkname')" == "/your/exact/path" ]; then rm -- "$lnkname"; fi; done
```
or nicely formatted
``` find -type l |
while IFS= read -r lnkname;
do
if [ "$(readlink '$lnkname')" = "/your/exact/path" ];
then
rm -- "$lnkname"
fi
done
```
The ```if``` could of course also include a more complex condition such as matching a pattern with ```grep```.
Tailored to your case:
```find -type l | while IFS= read -r lnk; do if (readlink "$lnk" | grep -q '^/usr/local/texlive/'); then rm "$lnk"; fi; done
```
or nicely formatted:
```find -type l | while IFS= read -r lnk
do
if readlink "$lnk" | grep -q '^/usr/local/texlive/'
then
rm "$lnk"
fi
done
```

Write a short story that describes a time when someone was faced with the inevitable destruction of their home.

A lantern shone atop a pole
Through shielded panes of glass
And brightly burned against a swollen
Cloak of smothering mass
Below it swirled, that blackened sheet
And sometimes it would climb
Along the stalk, then slip, retreat
Like now was not the time.
For all his life the flame stayed home
Atop his iron perch
Refusing calls to leave, to roam
And risk the monster's lurch
Until, one day, when wear and age
Had rendered all to rust
That cool and clear protective cage
Collapsed, returned to dust.
It's then the lantern knew at last
The end he could not halt
He blazed defiant, holding fast
And braced for the assault
But though in youth with verve and force
He swore to give a fight
His wick had run its proper course
And caved to endless night.

Como é possível que o banco de dados seja melhor do que um sistema de arquivos para armazen
|
Além do custo ser mais alto como mencionado, deve-se levar em conta vários fatores:
* Volume de dados: para um baixo volume de dados pode não haver problema. Por outro lado, para armazenamento de grande massa de dados o banco de dados é praticamente inviável. Pergunte ao Facebook ou ao Google se eles usariam banco. O Facebook, por exemplo, usa um sistema de arquivos personalizado para tornar o acesso mais rápido ainda e diminuir a o overhead por arquivo exigido pelos sistemas de arquivos tradicionais.
* Clusterização: uma vantagem do banco de dados é no caso do seu sistema rodar em vários servidores, todos terão acesso uniforme aos arquivos. Porém, usar uma unidade na rede para armazenar os arquivos.
* Disponibilidade: seu sistema vai ter muitos acessos? Isso pode sobrecarregar um banco de dados tradicional. Por outro lado, seu servidor HTTP pode usar as rotinas de acesso de baixo nível ao sistema de arquivos para enviar o stream de dados ao cliente.
* Escalabilidade: se a demanda de volume ou disponibilidade aumentarem, será possível adicionar mais capacidade ao sistema? É muito mais fácil dividir arquivos entre servidores diferentes do que distribuir registros de uma tabela em mais servidores.
* Flexibilidade: fazer cópias de segurança, mover arquivos de um servidor para outro, fazer algum processamento nos arquivos armazenados, tudo isso fica mais fácil se os arquivos estiverem num diretório. Se você faz o deploy em ambiente de cliente, os arquivos no disco não inviabilizam você de receber cópias do banco de dados para testes. Tente pedir para o seu cliente enviar terabytes de dados para você analisar se der alguma vantagem para ele, e veja como isso se parece com o custo de manutenção.
* Diferenças entre sistemas de arquivos: certas tecnologias de sistema de arquivo podem ser mais eficientes do que o sistema de arquivo do banco de dados. Por exemplo, o sistema de arquivo do banco de dados não permite a criptografia do arquivo.

None linger by his side but the bitter wind's empty murmur. Memories flickering by his mind's eye, he is reminded of his loss. The whole world seems to mock him, gibe him, twist him into comedy, surround him with sinister mirth.

So his misery wells up within him, woeful hysterics erupting from his very soul, echoing through this bitter new world.

Taking in information as it suits their personal agendas.
Ignoring the things that they wish not to see.
Assuming that no one else feels the way they do.

The implementation of ```std::function``` can differ from one implementation to another, but the core idea is that it uses type-erasure. While there are multiple ways of doing it, you can imagine a trivial (not optimal) solution could be like this (simplified for the specific case of ```std::function<int (double)>``` for the sake of simplicity):
```struct callable_base {
virtual int operator()(double d) = 0;
virtual ~callable_base() {}
};
template <typename F>
struct callable : callable_base {
F functor;
callable(F functor) : functor(functor) {}
virtual int operator()(double d) { return functor(d); }
};
class function_int_double {
std::unique_ptr<callable_base> c;
public:
template <typename F>
function(F f) {
c.reset(new callable<F>(f));
}
int operator()(double d) { return c(d); }
// ...
};
```
In this simple approach the ```function``` object would store just a ```unique_ptr``` to a base type. For each different functor used with the ```function```, a new type derived from the base is created and an object of that type instantiated dynamically. The ```std::function``` object is always of the same size and will allocate space as needed for the different functors in the heap.
In real life there are different optimizations that provide performance advantages but would complicate the answer. The type could use small object optimizations, the dynamic dispatch can be replaced by a free-function pointer that takes the functor as argument to avoid one level of indirection, but the idea is basically the same.
Regarding the issue of how copies of the ```std::function``` behave, a quick test indicates that copies of the internal callable object are done, rather than sharing the state.
```// g++4.8
int main() {
int value = 5;
typedef std::function<void()> fun;
fun f1 = [=]() mutable { value = 2; };
fun f2 = f1;
f2(); // 2
f1(); // 2
return 0;
}
```

Write a response that describes the task.

First of all I’d like to start by saying I ordered a cheap sword that was only supposed to look shiny so I could have a play sword fight with my son. Instead I accidentally chopped his sword in half and took one of his fingers with it. Along with him losing that finger I’ve now lost custody of my children. Thanks, assholes.
Secondly I now have the voice of God in my head and he won’t stop screaming. The only words he’s said to me are “It’s been far too long since I last checked in on my subjects. Let’s see how everything’s go-” and since then there’s been non-stop screaming which has kept me from sleeping for a week. On top of that I also am being told by the voices of angels that I need to “cleanse the world” of sinners. Specifically they keep telling me to go after some “Jack Paulers” and, after googling that, I don’t feel so bad about cutting off my son’s finger seeing as many parents have done much, much worse for their children.
Third and finally my biggest complaint of all; this sword is just too big. Honestly I think I’ll get used to the screaming of God and the angels can go shove a holy sword up their ass and somebody else can take care of all the Florida Men but this sword is bigger than the one I ordered. See I’d already ordered a cool holder for the sword so I could hang it on my wall when I wasn’t using it but the sword is too big and it doesn’t fit.
I wouldn’t suggest this product to anybody interested, it’ll make you lose your children, your privacy, your sanity, and any hope for humanity. 0/5
Sincerely, CrocsNSocks113.

The situation you're describing is tough. Layoffs have a very real impact on both the individuals that are let go and those that remain. I'm sorry you're experiencing this.
Here are some things to consider that may help you and your colleagues cope with the added stress and emotions following a layoff:
* Acknowledge the layoff and the feelings of your colleagues. Avoiding the topic can extend negative feelings and disenfranchise those most impacted. You should find an opportunity to connect with your colleagues for an honest conversation about your feelings following the layoff. Perhaps reach out to hold a number of 1-on-1 conversations, or gather your team for an off-site lunch and prompt the discussion.
* Acknowledge that everyone will be impacted differently. Some of your colleagues will feel totally okay and ready to get back to work. Others will feel anxious and worried in a way that prevents them from performing the same way they did before the layoff. There is no right or "professional" reaction to a layoff. Be open to the feelings and reactions of all of your colleagues equally.
* Create practical solutions to new processes and responsibilities. If your team now has a greater workload, be a generator of solutions. Try out ideas for making processes in your team more efficient and predictable.
* Create transparency about the state of the business and potential future staff changes. Layoffs are a clear indication of business trouble. Facilitate sharing facts about the state of the business and actively work to eliminate rumors. Additionally, layoffs will likely cause shifts in responsibility as roles are consolidated or reorganized. Make clear who has specific responsibilities both inside and outside of your team. Actively eliminate any sources of uncertainty and anxiety that you can.
* Be a role model. Don't participate in gossip or complaining about the layoff. Don't disparage management or other colleagues in casual conversation. Be a model for professionalism and caring.
* Maintain work standards and a caring meritocracy. A layoff isn't an excuse for allowing work standards to slip. A layoff shouldn't mean that your team stops working hard to meet deadlines and deliver quality work. Keep a caring meritocracy alive. Be a model of openness, empathy, and fairness. Your actions will inspire others.
* Don't give up. Layoffs can be demoralizing, and it's easy to start doubting yourself. Don't give up on your career, your team, or yourself. You're more resilient than you might think.
I hope that you and your colle

Tell me about a time you have run a task for a company.
|
Run (and run fast) - here are just a few points to consider:
* That's a very unorthodox task for somebody still in the interviewing stage.
* How you going to present a solution you aren't familiar with?
* Since you aren't an employee of said company yet you have no grounds to represent them or even hustle their products.
* You aren't on their payroll yet so why should you waste your time looking for customers?
* There are a bunch of legal issues arising from such a 'task' (think NDA etc..).
* How will your potential employer determine if your task has been carried out successfully?
* Any CEO/CTO or even higher management of any automotive company will NOT engage in such a conversation with a random stranger.
* Such an unprofessional approach is extremely disrespectful of the prospective customer's time.
These are all major red flags and should lead any mentally sane person to the conclusion that the person asked for such tasks is unreasonable and has no clue about business in general.
Additionally - what kind of impression do you think they will have of you or your potential, future employer considering the above mentioned points?
Thank them for their time and continue applying elsewhere because this company is a nut-house.

The following is an explanation of the uses of the underscore is Scala _ [underscore] magic.
Examples:
``` def matchTest(x: Int): String = x match {
case 1 => "one"
case 2 => "two"
case _ => "anything other than one and two"
}
expr match {
case List(1,_,_) => " a list with three element and the first element is 1"
case List(_*) => " a list with zero or more elements "
case Map[_,_] => " matches a map with any key type and any value type "
case _ =>
}
List(1,2,3,4,5).foreach(print(_))
// Doing the same without underscore:
List(1,2,3,4,5).foreach( a => print(a))
```
In Scala, ```_``` acts similar to ```*``` in Java while importing packages.
```// Imports all the classes in the package matching
import scala.util.matching._
// Imports all the members of the object Fun (static import in Java).
import com.test.Fun._
// Imports all the members of the object Fun but renames Foo to Bar
import com.test.Fun.{ Foo => Bar , _ }
// Imports all the members except Foo. To exclude a member rename it to _
import com.test.Fun.{ Foo => _ , _ }
```
In Scala, a getter and setter will be implicitly defined for all non-private vars in a object. The getter name is same as the variable name and ```_=``` is added for the setter name.
```class Test {
private var a = 0
def age = a
def age_=(n:Int) = {
require(n>0)
a = n
}
}
```
Usage:
```val t = new Test
t.age = 5
println(t.age)
```
If you try to assign a function to a new variable, the function will be invoked and the result will be assigned to the variable.
```val t = new Test
val f = () => println(t.age)
f
```
If you want to use the result of a function in another function, you need to assign it to a new variable.
```val t = new Test
val f = () => println(t.age)
f
val g = () => t.age
g
```
```// Usage of _ and _*
object Foo {
def bar(x:Int, y:Int): Int = x + y
}
object Fun extends scala.util.matching.

Want some Halloween food ideas? Well then look at this article.
## Step
1. Make Vampire punch. Your guests may be thirsty so here's the perfect drink: Vampire Blood Fruit Punch. All you have to do is buy/make some red fruit punch.
2. Serve bone crunch sandwiches. Put some salad on some white bread and add tomatoes and more. You choose!
3. Serve spider leg trail mix. Add some M&M's, Pretzel sticks, etc. in a bowl and there you go. Simple, easy and good.
4. Make some monster toes. Make the mini hot dogs, and then carve out a toenail area on the hot dog. Then dab ketchup on the "toenail".
5. Have some blind tasting. Serve the guests regular food, but tell gross stories, describing some disgusting objects with the same texture as the food.
6. Serve uncut blood oranges in water with red food coloring!
7. Make dirt- get a large bowl or clean flower pot and put some chocolate pudding in. Mix in crushed Oreos and gummy worms.
## Make dirt cake
1. Make Brownies. For best results, make them as gooey as possible.
2. Find chocolate accessories. Pour chocolate syrup on the finished brownies, then sprinkle them with coco powder. You could also consider adding little bits of a chocolate bar.
3. Add creepy crawlies. Put gummy worms and other gummy critters on top of and around the cake. Cover some of them with coco powder to make it look like they're coming out of the dirt.
4. Add flesh and guts. Melt red starburst, jolly rancher chews, and tootsie rolls. Then, tear them into chunks and spread them around certain parts of the cake. To make them look even more real, you can add them to the creepy crawlies from step 3.
5. Cover in spider webs. To make a spider web, simply take a large piece of wax paper, lay it out flat, and stick to it with spray adhesive. Then, sprinkle it with powdered sugar and cut it into strips.
6. Add candy bugs. You can buy these from a craft store, but you can also make your own. For the body, make a slit in a marshmallow and insert a candy corn. For the legs, make another slit in a different marshmallow and insert

###Piloting
A crew member who is controlling a helm gains one point of experience for each incoming projectile that is dodged during combat. This includes asteroids, so long as you are in combat at the time. (Note that the dodges do not count while you ship is under the effects of +60% evasion from a cloak.)
This can be explicitly trained by finding an enemy that cannot break through your shields, and letting him fire at you. Increasing your dodge chance (i.e. more power to engines) will help this occur quicker, but even with the default chance you can max out the skill eventually.
###Engines
Exactly as for piloting, a crew member manning the engines gains one point of XP for each projectile evaded while uncloaked in combat - and so it can be trained in the same way.
###Weapons
A crew member who is manning the weapons station gains one point of experience for each weapon that is fired. It doesn't matter whether it hits or misses, or whether it can do damage (e.g. a beam weapon fired at a shield).
(Multi-shot weapons such as burst lasers still count as a single fire order and hence a single XP.)
This can be trained by firing non-lethal weapons (e.g. ones that do ion damage) repeatedly against a target that cannot damage you.
###Shields
A crew member manning the shields station gains one point of experience for each shield "bubble" that is brought back up during combat. It doesn't matter why the shields were down, be that direct enemy fire, ion damage, asteroid strikes, or even manually removing and then restoring power to the shield systems.
This can be trained by letting a target that cannot break through all of your shields repeatedly take one layer down. (For fastest results, move your pilot away from the helm, or reduce your engines to 0 power. This will reduce your dodge chance to 0%, ensuring that everything hits your shields.)
Note that you used to be able to manually remove power and restore it in combat, to get XP, but that has been removed in a later patch.
###Cloak
A crew member manning the cloak station gains one point of experience for each cloak use. It doesn't matter whether it was used to cloak the ship, or to bring it back out of cloak.
###Evasion
A crew member manning the evasion station gains one point of experience for each evasion that is performed during combat. This can be trained by getting the evasion skill up high, and then using it to dodge attacks.

## The basics
1. Start with a short slackline. The shorter the distance between the two anchor points, the more stable the slackline. As the slackline gets longer, a few things happen:
* The tension in the line increases, making dismounts more dangerous due to the extra force;
* The height of the line off the ground increases to allow for greater sag when weighted;
* It requires more force to tighten it, which can be difficult with some tightening systems.
2. Place one foot lengthwise in the middle of the slackline. Starting barefoot is a good idea. Using bare feet will allow you to feel the line better and find your balance more quickly. Step on the line so that it runs from between your big toe and second toe back to the middle of the heel. As you improve, practice turning your feet and standing sideways, with your shoulders parallel to the line. Once you improve (or if the landing is not safe for bare feet), you may want to switch to shoes since they provide greater protection when attempting tricks and landing.
3. You can mount the slackline at any point, but starting in the middle is generally safer, since it is usually away from obstacles you might hit when falling. The line is also lower to the ground in the middle once weighted, reducing the height of the falls. Practice from the same place each time since the slackline oscillates differently at different distances from the anchors. The wobbles are faster and smaller near the anchors and slower and larger near the middle. But wherever you start, it is going to wobble a lot. This is natural; everyone wobbles the first time.
4. Take a couple deep breaths and settle yourself. If you are relaxed, your foot will be less shaky on the line.
5. Focus intently on a single point, such as the anchor. This will help you find and keep your balance. Resist the temptation to look straight down at your feet on the line. Looking down at the wobbling line will simply make you wobble as well. Look ahead instead of down at the line.
6. Put your arms out wide, slightly bent and keep an upright posture. Keep your back straight. It helps to keep your eyes focused on a point in front of you, such as a tree, and hold your head up.
7. Tighten your core muscles, and keep your legs slightly bent.
8. Once you are balanced, tighten your abs and tighten your legs.
9. When you are ready to dismount, tighten your core muscles and push your butt back, so you are sitting on your heels. This will help you balance better and make it easier to dismount.

I am planning on using ethernet cable to connect my computer to my router, however I have heard that the cable itself can add a small amount of delay to the connection. Will this make a noticeable difference to the speed of my connection, or is this negligible?
|
For all practical purposes, there will be no effect on the speed of your connection.
There will be a very insignificant amount of delay due to long cables. This won't affect the maximum speed of your connection, but it would cause some latency. pjc50 points out that it's about a nanosecond for every foot of cable length, which is a good rule of thumb used by many engineers when developing systems which are very dependent on latencies on those timescales.
In reality, you will never notice a difference. A "fast" ping time on the Internet is 10 ms, which is 10,000,000 ns. Adding even a few hundred feet of cable isn't going to have a noticeable effect at that point. In fact, nearly every step of the way involves delays which are more extreme than those seen from signal propagation. For example, most consumer grade routers will wait for the last byte of an incoming packet to be received and check it for errors before sending the first byte of the packet on its way. This delay will be on the order of 5,000 ns! Given that the maximum length of cable you can run (per the Ethernet spec) is 300 ft, the cable length could never cause more than 300 ns of delay due to the cable!

Write a poem that describes a scene of combat. The combat is between two armies of your creation. Each army has its own leader and its own strategy. The poem should tell the story of the battle. The scene should be from the perspective of the leader of the losing army.
|
I had never known such a weapon.
The stone hurtled through the air and stuck me down.
I tried. By all our Gods I tried.
The Israelites came, and we drove them back. I drove them back. For forty days I called my challenge to end this with single combat, the sight of my brothers dead around me had sickened my soul and poisoned my mind. I had to end this.
It was for naught. I strode out, my armour gleamed, my shield shone and my sword was sharp.
But I could not be ready for him.
For a stone to fly so fast. I would not have thought it possible. If only our own soldiers had such weapons.
I fell heavily, my bulk crashed hard weighed down by the armour.
I'm so sorry...
He took my head, and fed our corpses to the wild animals.
Run, David comes.

How can I comfort a dog in mourning?
|
## Comfort the dog
1. Spend extra time with the dog. A dog in mourning may need extra love and attention. Try to increase the amount of time you spend with the dog. You might spend twenty extra minutes in the morning and evening to help give the dog support while they are grieving the death of their owner. During this time, you can:
* Talk to the dog
* Walk the dog
*
* Groom the dog
*
* Go on a car ride
* Visit the dog park
* Pick out a new toy together at the pet store
* Cuddle the dog on the couch or in bed
* Take the dog for a run, if the dog is healthy enough
* Play a game, like fetch or tug-of-war
2. Pet the dog. Touch increases the bond between dogs and people. Extra cuddling, petting, and brushing can improve the dog’s mood and distract them from the loss of their owner. As you spend time with the dog, rub their belly or scratch their ears. Give them a little extra grooming time each week. This will help you bond and comfort the dog.
3. Play their favorite games. Playtime can distract the dog from the loss of their owner. The extra exercise can also boost their mood and decrease the likelihood of grief-related health issues. Try to identify the dog’s favorite games or toys, and spend extra time playing with them. Some older dogs may not want to play as much. Each dog is different. If the dog is uninterested in playing, you might try another way of distracting them. You can also give the dog new and interesting toys. Food puzzle toys can help keep the dog busy while you are not home, reducing the dog’s separation anxiety.
4. Invite company over. The dog may appreciate having people over to spend time with. Invite a few friends over, and see how the dog reacts. If the dog enjoys the company and socializes with the people, you may want to keep it up. If the dog avoids your guests, you should respect their space. However, if the dog is friendly, they may enjoy the company.
5. Try to make the dog’s routine as normal as possible. Dogs thrive on routine. If the dog has a regular feeding time, stick to it. If the dog sleeps on a specific bed, use it. If the dog has a regular time for walks, try to keep it.

Hi Jude,
I'm here to help you make some choices. Your life is a bit of a mess. You have been living in the past, and are afraid of getting hurt. I'm here to tell you that it's ok to love again, and to be vulnerable. If you find a good woman, don't be afraid to let her into your heart. Don't be afraid of making mistakes, as long as you learn from them. I'll be your guide, and your friend.
|
I say hello to the man called Jude
Asking that he make happier notes from sad tunes
Once you let inside your love, notes happier hued
Afraid not my dear man, for with the newer moons
You shall find your love, come into to happier places
Carrying too much upon yourself, with so much weight
Lying to yourself will lead only to dark spaces
You have found your love, now take the bait
Again, you must allow her access inside your heart
Do not play games of stop and go, it shall get better
Your will and love are strong enough start
So come now Jude, you must go out and get her

Dijkstra’s algorithm is very similar to Prim’s algorithm for minimum spanning tree. Like Prim’s MST, generate a SPT (shortest path tree) with a given source as a root. Maintain two sets, one set contains vertices included in the shortest-path tree, other set includes vertices not yet included in the shortest-path tree. At every step of the algorithm, find a vertex that is in the other set (set not yet included) and has a minimum distance from the source.
```
// The program aims to implement Dijkstra's single-source shortest path algorithm in C language.
// The program utilizes an adjacency matrix as the representation of the graph
#include <limits.h>
#include <stdbool.h>
#include <stdio.h>
// The number of vertices present in a graph.
#define V 9
// A function that is used to identify the vertex with the smallest distance value
// among a set of vertices that have not yet been included in the shortest path tree.
int findMinDistance(int dist[], bool sptSet[])
{
// Initialize min value
int min = INT_MAX, min_index;
for (int v = 0; v < V; v++)
if (sptSet[v] == false && dist[v] <= min)
min = dist[v], min_index = v;
return min_index;
}
// A utility function to print the constructed distance
// array
void printSolution(int dist[])
{
printf("Vertex \t\t Distance from Source\n");
for (int i = 0; i < V; i++)
printf("%d \t\t\t\t %d\n", i, dist[i]);
}
// a function that applies Dijkstra's algorithm for finding the shortest path between
// a single source node and all other nodes in a graph. The graph is represented using
// an adjacency matrix.
void dijkstra(int graph[V][V], int src)
{
int dist[V];
bool sptSet[V];
// Initialize distance
for (int v = 0; v < V; v++)
dist[v] = INT_MAX;
dist[src] = 0;
// Identify the vertex with the smallest distance value
for (int v = 0; v < V; v++)
if (dist[v] == INT_MAX)
dist[v] = findMinDistance(dist, sptSet);
// Create the shortest path tree

Silent Hill 3 is the third installment in the Silent Hill video game series. It is considered to be a survival horror video game in which your character must solve different puzzles and psychological challenges in order to advance. The Shakespeare puzzle can be found during the Shopping Center stage. It’s inside a bookstore called My Bestsellers.
## Solve the puzzle on easy mode
1. Pick up the Shakespeare books that have fallen on the ground. In this difficulty, there will only be 2 books on the ground: Anthology 1 and Anthology 3.
2. Examine the bookshelf. You’ll be allowed to place the books you found on the floor in the empty slots.
3. Click on Anthology 1 and place it on the first slot of the bookshelf.
4. Click on Anthology 3 and place it on the third slot on the bookshelf. A code will appear after placing the two books correctly.
5. Use the code on the door at the back side of the bookstore. In this puzzle, you only need to arrange the books in the proper order: (from left to right) Anthology 1, Anthology 2, Anthology 3, Anthology 4, and then Anthology 5.
## Solve the puzzle on normal mode
1. Read the note on the door. It will read “Fair is foul, and foul is fair. Put these books out of order.”
2. Pick up all the books on the floor. There will be 5 books in normal mode.
3. Examine the bookshelf. You’ll be allowed to place the books on the empty space on the shelf. Put the books in randomly; order doesn’t matter as this puzzle is generated randomly.
4. Take a good look at the books. You’ll see there are black markings on it; this is the code you need.
5. Arrange the books until you get the correct order. It won’t be too hard as the numbers are written quite obviously. Try to make out the numbers written on the spine of the books and keep moving them until you get it right.
## Solve the puzzle on hard mode
1. Read the note on the door. It will read “Fair is foul, and foul is fair. Put these books out of order.”
2. Pick up all the books on the floor. There will be 6 books in hard mode.
3. Examine the bookshelf. You’ll be allowed to place the books on the empty space on the shelf. Put the books in randomly; order doesn’t matter as this puzzle is generated randomly.
4. Take a good look at the books. You’

Describe a utopian society.
|
Smooth edges. Clean streets. People bustle about, heading to lunch, with smiles on their faces. Posters line the walls of the city saying "Be Your Brother's Keeper" or "Arcadia is Our Mother". Loudspeakers chime in with daily reminders about citywide events or milestones met. "Without Arcadia," says the woman on the announcements, "we are nothing." Police in crisp white uniforms patrol the streets on foot, and everyone smiles and nods at them. Above, through the small clouds, an impossibly tall tower can be seen standing at the center of the sprawl.
A great wall surrounds the city. The First Founders began building it long ago, during their age, and by the time their generation had passed it was finished. A dull grey barrier, blocking Arcadia off from the outside world. Every man, woman, and child knows what lies beyond. Ruins of the fallen world, the world that came before. Anyone is free to leave, but such a thought rarely ever crosses the mind. They are taught the truth when they are young, how societies collapsed after fossil fuels ran out. How wars were fought not for land, but for water. How the nuclear missiles, the Dust Makers, were made. How terrifyingly destructive they had been. How they had sailed through the air like shooting stars before crashing back down to Earth like meteors.
They picked through the ashes and learned from their ancestor's mistakes. They come together as a community, and stay together as a community, for each other's sake. Division, the teachers said, is what split the old world apart. People were separated, not just by the borders of their country, but by the borders they made themselves. Race. Class. Religion. Political views. In Arcadia, these things still exist, but the people are taught to embrace their difference. To cherish it. To not let it consume and divide them.
Because if there is division, there is no Arcadia. And without Arcadia, they are nothing.

Write a story of 300-500 words where a young man named George Washington discovers a thin, white book on the ground. He picks it up and finds it is a small, black notebook with the phrase "I'm a book of my own" written on the front. Write the story, explaining the events that occur after he discovers the notebook.
|
The young man was walking by the street when he stepped on a small, thin, white book. He looked at it, kneeling down to pick it up. The man analyzed it left to right. It looked familiar, like one of those Anime's he watched, except the wording was different. It said life instead of death, which was weird.
The man thought nothing of it, simply taking oht a pen from his shirt pocket and writing the first name to come to mind. Of course the first president was the first name. He wasn't very creative, so he sloppily wrote it down, throwing the notebook down afterwards and walking off.
The next day, he was making breakfast, looking at the tiny tv sitting in the kitchen until he heard something he never thought he'd hear from a news source.
"George Washington is alive? Is it an imposter? He seems to be very serious about it."
The mans jaw gaped open, seeing pictures of the man in the modern era.
"Guess he'll have to survive this."

Why do the Arabic letters "K" and "Q" have different sounds in English?
|
In Arabic, in fact, they've always been separate sounds! The sound we write "K" is spelled with the letter ك in Arabic, and is pronounced a little bit further forward in the mouth; the sound we write "Q" is spelled with the letter ق and pronounced a little bit farther back. In phonetic terms, "K" is a velar sound, and "Q" is a uvular sound.
English doesn't distinguish between these two different sounds. But since we've got a spare letter lying around—the English letter "Q" is actually related to the Arabic letter ق, if you go back far enough!—it's become conventional to separate them in writing. "Kuwait" is spelled with a ك, so it gets a "K"; "Qatar" is spelled with a ق, so it gets a "Q". The "Qur'an", similarly, has a ق in it.
Nowadays, by the way, the letter "Q" has started to be associated with Arabic in particular, since it shows up significantly more there than in English. So in pop culture, you'll sometimes see names like "Hakeem" respelled to "Haqim"—even though the original Arabic has a ك in it! Linguistically, this is called hypercorrection, and it's the same reason you'll see words like "forté" with an é: English-speakers associate the acute accent with Romance loans (café, fiancé, résumé), but it has no special meaning in English, so it sometimes gets inserted where it doesn't actually belong (the original Italian word is simply forte).

You dropped a screw while installing your new computer. You don't have any extra screws. You're pretty sure it's buried in your carpet, but you don't have the time to go digging through it. You need to find the screw, but you can't afford to buy new ones. What can you do?
|
This is why you should always have spare screws on hand. Fortunately, there is a way:
## Light Method
Most screws are silver. Shine a flashlight into the carpet and look for little silvery glints. This may take some time, but you'll probably find it. If your carpet is unnaturally thick...
## Magnet Method
Take a powerful magnet (like a bar magnet, hardware stores - fridge magnets might work) and run it over the surface where you think the screw is. You should find it. If that still fails...
## Vacuum Method
Take a good vacuum cleaner. Put a sock over the extending arm, and run it over where you think the screw is. The sock will prevent the screw from being vacuumed up, but it will be stuck to the sock. There will still be enough suction to pick up the screw, even with the sock. If not, get a new vacuum! If that fails...
## Organize your screws
There are many useful tools to organize screws. Go to your local RadioShack and get one, or make one out of a magnet for that awesome lifehack feel.
## Stop using carpet!
[Not a "find your screws" method - a tip about not frying your computer]
Carpet can cause static discharge, which is very very very bad for a computer (personal experience). Work on a hard floor with an antistatic strap to reduce the chance of frying your PC.

What is the "cards speak" rule in a poker game? Can a player say that a person has a certain hand and then the dealer awards the pot to the player who had the best hand? What are the caveats for this rule? What happens if a player deliberately overcalls his hand to induce a player with a better hand to fold?

Casinos in the US generally have the "cards speak" rule. That is, when a hand is properly tabled--exposed to everyone at showdown--it is the responsibility of all players, the dealer, floormen, and anyone else present to see that the pot is awarded to the best hand shown, regardless of what the players might say.
Some players object to this rule: they believe that if a player or railbird says "Wait, Bob has a flush", that's unfairly helping a player. But the rule is clear: once the hand is tabled, others have not only the right but the obligation to help ensure the pot is awarded correctly.
There are a couple of caveats: if a player only shows his hand to another player, or to the dealer, or to any other person, without properly tabling it for everyone, that player has no rights yet and those to whom the hand was shown should remain silent to protect other players' properly shown hands. But once the hand is tabled, it's fair game and everyone can and should assist in reading the hands.
Finally, in some cases, if a floorman feels that a player has deliberately overcalled his hand to induce a player with a better hand to fold, he may penalize that player by awarding the pot to someone else, even possibly to a folded hand. Some California lowball clubs even had a rule that a player who remained silent rather than explicitly calling out a pair could be ruled against in this way.

How can I sort a list using Python? I would like to know how to do it with list.sort() and sorted().
|
Python provides two ways to sort a list, the built-in list method `list.sort()` and the built-in function `sorted()`.
The primary difference between the two is that list.sort() will sort the list in-place, mutating its indexes and returning None, whereas sorted() will return a new sorted list leaving the original list unchanged. Another difference is that sorted() accepts any iterable while list.sort() is a method of the list class and can only be used with lists.
Here is an example of using `list.sort()`:
```
# the list to be sorted
x = [2, 3, 1, 5, 6, 4, 8]
# sort by list.sort()
x.sort()
print(x)
```
The output of the above code is
```
[1, 2, 3, 4, 5, 6, 7, 8]
```
Equivalently, you can use `sorted()`:
```
sorted_x = sorted(x)
```
