] | Download something like [Sublime](https://www.sublimetext.com/) and highlight the code. Spaces will be dots and tabs will be dashes. | I put that code in my editor and it compiled just fine. So I went to line 12 where you have `sieve = [True] * n` and got rid of the indentation so it was indented the same as the line above it `def primes(n):` and I was able to recreate your error.
Perhaps try and add an additional indentation than you think. You can also try Enthought Canopy which is free if you go to a university if you want a different editor. |

67,779,344 | I am trying to compile an Alpine Go container which uses [GORM](https://gorm.io/docs/connecting_to_the_database.html#SQLite) and it's [SQLite driver](https://github.com/go-gorm/sqlite) for an in-memory database.

] | I'm not sure if this is what you ask, but you cannot (well, it depends...) reverse a hashing algorithm to acquire an original password from the hash. You do the opposite: hash password provided by the user and check if a resulting hash is the same as the one stored earlier:
```
if (user == "user" && password == md5("1234")) {
``` | You should not store user credentials on the device, encrypted or not. If the user uninstalls your app or clears cache, they will be locked out. They also would not be able to log in from another device. Credentials should be handled by the server.
To encrypt passwords you should use a library like bcrypt. It allows you to salt the hash, making it very difficult to decrypt. Again, this should be done in your backend.
If you really want to do this on the device, this is a good resource

You can even re-map them all you want! | In a code block, you can use "Code block start" and "Code block end" actions (Cmd-Alt-[, Cmd-Alt-] in the default Mac keymap, Ctrl-[ and Ctrl-] in the default keymap on other operating systems).

6,144 | I'm currently in a weird situation - I have a large amount of accrued debt (85k principal, ~15k accrued interest so far), spread amongst multiple smaller student loans. Some are federal stafford loans, which were taken out at Max, and some are large private student loans.
Currently, I'm paying them at minimum through each loan, and paying some money directly to the principal whenever I can. The problem is that with so many loans (8 different loans through four different lenders), it's very easy to forget and miss a payment, and I may have been late once or twice. (wince.)

Going through a Government Agency as opposed to a private lender might reduce the burden (co-signers, collateral) you need to pass to get the loan. | I can't help you with consolidation, but I'd suggest automating as much of the payments as possible.
* Do your lenders support automatic debit of your checking for the payments?
* Can you use online bill pay to make the payments?
If not, you might take a look at any of the numerous online banks that have online bill pay, and open an account with them. (E.g. ING Direct, Ally, etc.) You can set up the online account to pull from your current checking/savings account, and then make payments from that online account to your loans.
When you have that set up, if there is some extra payment you want to make, you can set up an automatic additional periodic payment to get rid of one lender at a time until everything is paid off. |

] | To add to @bstpierre's answer, you should automate all your loans except for the one with the highest interest rate. Leave that one manual, and pay the most you can afford each month, to pay it off as quickly as possible. Once you finish that loan, move to the next highest interest rate.
Ultimately, this won't be quite as convenient as just having 1 loan. The differences are:
1. You need to set up all the automatic payments. This is probably comparable to in complexity of consolidating your loans.
2. Each time you finish one loan, you need to turn off an automatic payment, and start doing the next loan manually. If you organize yourself well initially, you'll know exactly what order to do the loans in, so this shouldn't take too long.
However, unless your consolidated loan has the same interest rate of your cheapest current loan, you will likely save money over-all by using this method. | The U.S. Department of Ed offers Loan consolidation that you may want to take a look at:

59,808,007 | I'm working on this guessing game where the user needs to guess the word in under 6 tries. They have the ability to try and guess the whole word but if guessed incorrectly the game ends. When the game ends it gives them the option to play again. My problem is that when I try to guess the word for the second time it gives me an error only when I enter `n` character.
I'm later going to replace add an array instead of the static BRAIN word and randomize it but I want to figure this out.

letterGuess = letterGuess.toUpperCase() ;
/* increment number of guesses */
//numGuesses += 1;
/* player correctly guessed a letter--excract string in wordSoFar
* up to the letter guessed and then append guessed. letter to that
* string Next, extract rest of wordSoFar and append after the guessed
* letter
*/
if (SECRET_WORD.indexOf(letterGuess) >= 0) {
updatedWord = wordSoFar.substring(0, SECRET_WORD.indexOf(letterGuess));
updatedWord += letterGuess;
updatedWord += wordSoFar.substring(SECRET_WORD.indexOf(letterGuess)+1,
wordSoFar. length() ) ;
wordSoFar = updatedWord;
}else {
numGuesses += 1;
}
/* display guessed letter instead of dash */
System.out.println(wordSoFar + "\n");
} while (!letterGuess.equals(FLAG) && !wordSoFar.equals(SECRET_WORD) && numGuesses < 6);
/* finish game anil display message anil number of guesses */
if (letterGuess.equals(FLAG)) {

}
if (wordGuess.equals(SECRET_WORD) || wordSoFar.equals(SECRET_WORD)) {

Since you are doing everything manual right now (building & test) I would also deploy manually, that can also mean that you write some scripts that check the right version out from subversion and deploy it to whatever environment you want it to.

We are starting to use Hudson for testing and deployment (at least for the sandbox environment). We don't intend to use it for production. Because we did not check into the promotion plugin yet. When researching CI servers, I noticed that commercial systems usually offer a better support for release management. | There are several ways that you can do this:
**Use a build server**
I've heard of teams using CCNET.net or FinalBuilder Server for this. Basically, what happens is that the build script has code to push the latest build, every time somebody makes a check in. I wouldn't recommend this for production though. This should work fine for a staging environment though.
I'm not very familiar with build servers on Linux, but I know that there are a few. There's also Ant, and even Make scripts that could be used for this.
**Put a working copy on the staging server**
Just do a check out, and map the correct folder to be the root of the web app. Somebody on the team will have to manually update this working copy, but this gives you the flexibility to revert to a previous version if necessary.
**Caveats**
You'll need to make sure that you exclude the .svn folders when you pointing the website to the working copy.

When researching CI servers, I noticed that commercial systems usually offer a better support for release management. | This question is really a question about release procedures (and tools), rather than system administration, but here's my best answer:
Any recent version of Subversion takes excellent care of your configuration management needs, but, like Peter said, it's not a deployment tool. One option would be to build deployment into your regular build infrastructure (e.g 'make deploy') and manage your deployment rules alongside your code.
From a configuration management point of view, you need to keep track of everything your application needs to function, including code, external libraries (in specific versions), webserver, OS versions, etc. 'make deploy' should try to ensure all those things exist before it attempts to deploy a new version.
Tools like Hudson can also handle deployment for you, but you'll still need to tell it what to do and I simply prefer to keep my configuration management procedures as simple as possible. One example would be to let Hudson invoke 'make deploy' but store no other information in Hudson that you'd need to recover to recreate on additional machines.
How often are you going to be doing releases that need to be deployed? I would consider something along the lines of tagging your webapp into tags/ and having a post-commit mechanism that knows that tags/webapp-1.0.4 needs to be exported to your webroot. If your webapp is large, consider having the hook drop a special file in /tmp which a cronjob checks every minute and takes appropriate action on.
If you want more detailed answer, please elaborate on your release schedule, size of codebase, choice of language, OS environment and dependencies. |

Take $v' = v \odot \pi$ as the new output probability of your model, where $\odot$ denotes an element-wise product.
Now, your question can be reformulate to this: Finding the $\pi$ which optimize the metrics you have specified (eg. `roc_auc_score`) from the new output probability model. Once you find it, the $\theta s (\theta\_1, \theta\_2, ..., \theta\_N)$ is your optimal threshold for each classes.
The Code part:
---
1. Create a `proxyModel` class which takes your original model object as an argument and return a `proxyModel` object. When you called `predict_proba()` through the `proxyModel` object, it will calculate new probability automatically based on the threshold you specified:
```
class proxyModel():
def __init__(self, origin_model):
self.origin_model = origin_model
def predict_proba(self, x, threshold_list=None):
# get origin probability
ori_proba = self.origin_model.predict_proba(x)
# set default threshold
if threshold_list is None:
threshold_list = np.full(ori_proba[0].shape, 1)
# get the output shape of threshold_list
output_shape = np.array(threshold_list).shape
# element-wise divide by the threshold of each classes
new_proba = np.divide(ori_proba, threshold_list)
# calculate the norm (sum of new probability of each classes)
norm = np.linalg.norm(new_proba, ord=1, axis=1)
# reshape the norm
norm = np.broadcast_to(np.array([norm]).T, (norm.shape[0],output_shape[0]))
# renormalize the new probability
new_proba = np.divide(new_proba, norm)
return new_proba
def predict(self, x, threshold_list=None):
return np.argmax(self.predict_proba(x, threshold_list), axis=1)
```
2. Implement a score function:
```
def scoreFunc(model, X, y_true, threshold_list):
y_pred = model.predict(X, threshold_list=threshold_list)
y_pred_proba = model.predict_proba(X, threshold_list=threshold_list)
###### metrics ######
from sklearn.metrics import accuracy_score
from sklearn.metrics import roc_auc_score
from sklearn.metrics import average_precision_score
from sklearn.metrics import f1_score
accuracy = accuracy_score(y_true, y_pred)
roc_auc = roc_auc_score(y_true, y_pred_proba, average='macro')
pr_auc = average_precision_score(y_true, y_pred_proba, average='macro')
f1_value = f1_score(y_true, y_pred, average='macro')
return accuracy, roc_auc, pr_auc, f1_value
```
3. Define `weighted_score_with_threshold()` function, which takes the threshold as input and return weighted score:
```
def weighted_score_with_threshold(threshold, model, X_test, Y_test, metrics='accuracy', delta=5e-5):
# if the sum of thresholds were not between 1+delta and 1-delta,
# return infinity (just for reduce the search space of the minimizaiton algorithm,
# because the sum of thresholds should be as close to 1 as possible).
threshold_sum = np.sum(threshold)
if threshold_sum > 1+delta:
return np.inf
if threshold_sum < 1-delta:
return np.inf
# to avoid objective function jump into nan solution
if np.isnan(threshold_sum):
print("threshold_sum is nan")
return np.inf
# renormalize: the sum of threshold should be 1
normalized_threshold = threshold/threshold_sum
# calculate scores based on thresholds
# suppose it'll return 4 scores in a tuple: (accuracy, roc_auc, pr_auc, f1)
scores = scoreFunc(model, X_test, Y_test, threshold_list=normalized_threshold)
scores = np.array(scores)
weight = np.array([1,1,1,1])
# Give the metric you want to maximize a bigger weight:
if metrics == 'accuracy':
weight = np.array([10,1,1,1])
elif metrics == 'roc_auc':
weight = np.array([1,10,1,1])
elif metrics == 'pr_auc':
weight = np.array([1,1,10,1])
elif metrics == 'f1':
weight = np.array([1,1,1,10])
elif 'all':
weight = np.array([1,1,1,1])
# return negatitive weighted sum (because you want to maximize the sum,
# it's equivalent to minimize the negative sum)
return -np.dot(weight, scores)
```
4. Use optimize algorithm `differential_evolution()` (better then fmin) to find the optimal threshold:
```
from scipy import optimize
output_class_num = Y_test.shape[1]
bounds = optimize.Bounds([1e-5]*output_class_num,[1]*output_class_num)
pmodel = proxyModel(model)
result = optimize.differential_evolution(weighted_score_with_threshold, bounds, args=(pmodel, X_test, Y_test, 'accuracy'))
# calculate threshold
threshold = result.x/np.sum(result.x)
# print the optimized score
print(scoreFunc(model, X_test, Y_test, threshold_list=threshold))
``` | This was helpful, thanks! But it is not applicable during model training. When it comes to using this method after training the model (after finding the hyperparameters relevant to the model), it's valid; only that there has to be some way of standardizing this to avoid loss of generality and for it to be applicable on test data. |

] | Well, let me teach you a trick to you do not need an extension to "see" the elements if is that you want.
You can paste it in the console of the developer mode. It will create an mouse event that will capture the tag which you mouse over, then outline it with random color:
```
document.addEventListener("mouseover", function(e){
e.fromElement.style.outline = "";
e.toElement.style.outline =
'1px solid rgb(' +
Math.floor(Math.random()*256) + ',' +
Math.floor(Math.random()*256) + ',' +
Math.floor(Math.random()*256) + ')';
})
```
**This one is more interesting because it leaves a trail of edges:**
```
javascript:document.addEventListener("mouseover", function(e){
e.path.forEach(function(i){
i.style.outline=
'1px solid rgb(' +
Math.floor(Math.random()*256) + ',' +
Math.floor(Math.random()*256) + ',' +
Math.floor(Math.random()*256) + ')';
})
});
document.addEventListener("mouseout", function(e){
e.path.forEach(function(i){
i.style.outline="";
})
});
```
A best trick is to create a false favorite, and then edit it adding `javascript:` before the code.
-------------------------------------------------------------------------------------------------- | Which debugger are you using? if you are debugging layout for elements you can simply add the below line in css of a webpage to show outlines, like this:
```css
* {
outline: 1px solid red;
}
```
For example:
```css
* {
outline: 1px solid red;

] | Java doesn't provide a native method to achieve that. The easiest way might be to use NFS mount the other computers' disks to your computer, then your Java code could operate those remote disk just like local disk. | First, you have to share the file over the Network, and give the remote computer read/write permissions to all the files. Then you can use the java.nio classes to do it very easily:
```
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
public class MoveRemoteFiles
{
public static void main(String[] args) throws IOException
{
String originalLocation = "\\\\NETWORK-LOCATION\\MyFile.txt";
String newLocation = "\\\\NETWORK-LOCATION\\MyFile_2.txt";
Path originalPath = Paths.get(originalLocation);
Files.move(originalPath, Paths.get(newLocation));
}
}
```
And regarding the listing of all files, I'd recommend using the [Apache Commons IO](http://commons.apache.org/proper/commons-io//) library with the `FileUtils.listFiles()` method to save time engineering your own solution, like so:
```
import java.io.File;
import java.util.Collection;
import org.apache.commons.io.FileUtils;
public class ListRemoteFiles
{
public static void main(String[] args)
{
String originalLocation = "\\\\NETWORK-LOCATION\\Folder\\";
//List all files of all extensions (No Folders)
Collection<File> files = FileUtils.listFiles(new File(originalLocation), null, true);
//List all files and folders
Collection<File> filesAndFolders = FileUtils.listFilesAndDirs
(
new File(originalLocation),
TrueFileFilter.INSTANCE,
TrueFileFilter.INSTANCE
);
}
}
```
And then you can use the method above to move them after. |

If you still want to keep the declarations is rather a matter of style (but will get important when managing code in different compilation units, as you'd then have the declarations in header files – you'll encounter soon in next lessons). | Reason is variables are not defined before they are used.
Following changes added to the code.
* since you have named functions as "getSomeValue()" better to use a return type instead of void.
* its better to use double instead of int, because there are divisions in the calculation
* also used nested function calls to reduce number of lines of code.

1. You have function declarations which are redundant. You only need them if you plan on calling the function before the definition.
2. In your main method, you don't declare gallons
3. In your main method, you don't give values for wall and pricepaint.
4. In your functions, you operate via side effects, meaning you print to the console, rather than returning anything. |

] | Reason is variables are not defined before they are used.
Following changes added to the code.
* since you have named functions as "getSomeValue()" better to use a return type instead of void.
* its better to use double instead of int, because there are divisions in the calculation
* also used nested function calls to reduce number of lines of code.
Fixed Code:
```
#include <iostream>

int getGallons(int wall);
int getHours(int gallons);
int getCostpaint(int gallons, int pricePaint);

51,983,019 | Skip to EDIT2 which works
There is:
* Project (has\_many :group\_permissions)
* GroupPermission (belongs\_to :project)
I have a form where you can create a new project. A project has several attributes like name, status etc. and now important: iit. iit is selectable with radio buttons: yes or no.
What I want:
If someone selects **yes** on iit in the Project form, there should be a new record in GroupPermission. So in EVERY project where iit= 1 there should be a certain GroupPermisson.
Can I make / check this in the GroupPermission model? Like if
```
class GroupPermission < ActiveRecord::Base
if Project.where(iit: 1)
make me a record for each project
end
```
Can I even make database entries in the model like so?
Is this the right way?
**EDIT1:**
In the Project controller I added:
```
if params[:iit] = 1
record = GroupPermission.new(cn: 'ccc-ml', project_id: params[:id])
record.save
end
```
It then adds a new record in GroupPermissions. But I need the :id of the project. How can I access the id of the project which is about to be saved?
**EDIT2**
In the Project Controller
```
after_filter :iit_test, :only => [:create]
...
private
def iit_test
if @trial.iit == 1
record = GroupPermission.new(cn: 'ccc-ml', project_id: @project.id, name: 'CATEGORY_3')
record.save
end
```
end
EDIT2 works fine. I just have to check it with update etc.

] | add your inputformatter as the first formatter `InputFormatters.Insert(0,new StringRawRequestBodyFormatter())` then in this formatter in CanRead method check if the parameter that is being bound has a custom attribute you specify alongside FromBody
```
public override Boolean CanRead(InputFormatterContext context)

if (context == null)
throw new ArgumentNullException(nameof(context));
var contentType = context.HttpContext.Request.ContentType;
if (supportedMimes.Contains(contentType) &&
context.Metadata is DefaultModelMetadata mt &&

Controller action:`public IActionResult BeginExportToFile([RawJson,FromBody] string expSvcConfigJsonStr)`
So in simple terms this formatter will only be used for the supported mimes and for parameters that have a custom attribute.
Hope it helps. | Yes this can be in the Startup.cs by adding a new route in the config method, you should have something like this by default you need to add a new one for the controller that you want:

app.UseMvc(routes =>
{

The incorrect placement of the dividend is shown by the code output:
To solve the problem correct the first row `\cline` to `\cline{2-7}` and second row as `\multicolumn{5}{c}{24811.48}` then make consistent number of `&`s in all rows:

As pointed out by @egreg, however, the markup becomes too complex, especially if we also need align the digits (10 columns at least may be needed in this case). Yet a simple markup solution (three columns) with a typographically pleasing output plus aligned digits can be the following:
```
\documentclass{article}
\begin{document}
\[
\setlength{\arraycolsep}{0pt}
\begin{array}{rcl}
& & 7.24 \\ \cline{2-3}
3427\,&\big)\,& 24811.48 \\
& & \underline{23989_{}} \\ %\cline{3-3}
& & \phantom{23}{8224} \\
& & \phantom{23}\underline{6854_{}} \\ %\cline{3-3}
& & \phantom{23}{13708} \\
& & \phantom{23}\underline{13708_{}} \\ %\cline{3-3}
& & \phantom{231370}0 \\
\end{array}
\]
\end{document}
```
I used `\phantom{}` for alignment and replaced the `\cline`s with `\underline{}` to exactly fit the digits above. The extra `_{}` inside each `\underline{}` is to lower the line a bit for improving the visual appearance. | Are you looking for a long division? How about something like this:

While all the answers you have been given thus far are absolutely correct, what they are failing to understand is what is the underling question: How to I, as a 'total geek with a need to control all aspects of my techno-life" (<- tongue and cheek), gain total control over MY machine?!
I get this... I hate when apps and processes are run on my machine and I don't understand what they are doing.
Let me first point you too a really great site that will give you a clear list of each process that is running :http://triviaware.com/macprocess/all. This site will let you upload a text file (that you collect threw your terminal app by running:
"ps -A > process.txt". You will then upload it and get the definitions of each thing you are running.
Once you have that info you will be able to determine what you might be able to kill off and if you really want to.
Next spend a little time in your ~/Library folder and look into "LaunchDaemons" & "LaunchAgents". This is where all the process that start up with your account live. You should also look into your "StartupItems" while your there.
Now if your really want to go crazy look into your /System/Library folder and look at the same folders in there. This is where all the process are that Apple wants you to run. You can go nutz!
All that said I give you this fair warning!!!! Mess around in these folders all you want but know you can TOTALY SCREW UP your machine to the point of needing to do a total rebuild. So before you start make a complete and total backup of everything!!!
So from one control freak to another... Good luck in your chase to become a master of your environment! It's taken me 28 years and I'm only 3/4 of the way there. :-) |

Write
```
while(.... lots of conditions ...)
{
//stuff
}
```
Notice the lack of the `;` in the 2nd one.
Other than that, what if you had to check for the word `Pneumonoultramicroscopicsilicovolcanoconiosis`. How many combinations of upper & lower cases would you end up checking?
Instead, convert the input into upper case & compare against upper case `YES` or `NO` or `PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS`. | A control statement executing a single line of code can be written in two different way.
```
if (optketchup == "yes") {
slcketchup = "with";
}
```
```
if (optketchup == "yes") slcketchup = "with";
```
Also the following code is valid; the difference is that there isn't any instruction to execute when `optketchup` is equal to `"yes"`.
```
if (optketchup == "yes");
```
This is true for other control statements, such as your `while`.
Also, `=` is the assignment operator, while `==` is the comparison operator. You are using the latter when you wanted to use the first.
Then, as others already pointed out, just convert `optketchup` to lowercase: You will just need to compare the lowercase value with `"yes"`, instead of checking any possible variant of "yes" written using a mix of lowercase/uppercase characters. |
31,037,749 | Is there any way to disable selection of multiple columns for a Swing JTable? I've disabled selection all together in the "Tid" column by overriding the selection intervals of the selection model:
```
myTable.getColumnModel().setSelectionModel(new DefaultListSelectionModel() {
private boolean isSelectable(int index0, int index1) {
return index1 != 0;
}
@Override
public void setSelectionInterval(int index0, int index1) {
if(isSelectable(index0, index1)) {
super.setSelectionInterval(index0, index1);
}
}
@Override
public void addSelectionInterval(int index0, int index1) {
if(isSelectable(index0, index1)) {
super.addSelectionInterval(index0, index1);
}

I realised upon reviewing the JavaDoc and the `DefaultListSelectionModel` that the `index0` and `index1` were just what I was looking for - the column span. So by doing the call to the superclass if and only if the two column indices are equal, selection of multiple columns is not possible. |

You should actually use the single line (which in your case is called `lines` or rephrase your variables).
Thus, think about this here:
```
for line in text:
data = line.strip().split(',')
```
Do you see the difference? `lines` and `line`?

Also, reading the comments and the provided files, you should `split(',')`.
Or even better, use the [csv](https://docs.python.org/2/library/csv.html) module, that comes with a csv reader. |

23,396,053 | I'm calculating the determinant of a matrix, the calculations and therefore a method is called depending on the dimensionality of the data, for example:
```
template<int X, int Y>
float determinant(X, Y, std::vector<Vector> &data)
{
// Determine the dimensionality of matrix data (x and y)
}
```
The problem that I am having is that in the class that calculates the PCA, which calls this function, only accepts an iterator:
```
class PCA {
public:
template<typename T>
PCA(T begin, T end)
{
// Determine the X and Y here
float det = determinant(X, Y, ....);
}
};
```
Now I am wondering whether or not it is possible to deduce the `X` and `Y` from the iterator that has been passed through PCA, rather than passing in two integer values.
Any advice would be greatly appreciated
EDIT:
Apologises, my question was not clear.
Basically, `typedef std::vector<double> Vector;` is used so therefore `std::vector<Vector> data;` would therefore be a vector of vectors.
I sample this doing the following:
`std::vector<Vector> data1 = { {1, 2}, {3, 4}, {5, 6}, {8, 9} }; // 2x2` whereas when I want to add the following: `std::vector<Vector> data2 = { {1, 2, 3}, {4, 5, 6}, {7, 8, 9}, {10, 11, 12} }; // 3x3` so obviously, when calculating the determinant there is a different calculation for this.
I want to deduce that data1 is a 2x2 and data2 3x3 from the function without having to specifically pass these values in. | 2014/04/30 | [

] | Since vectors aren't fixed-size, they could be jagged. (Constrast this with, e.g. `std::array<>` or `T [N][M][L]`; you could deduce their ranks at compiletime).

] | As [Jonathon Reinhart noted](https://stackoverflow.com/a/32674865/1256452) you just need to diff commit `s` against the tip of `feature`. As you noted, you forgot to mention that you want to have git find commit `s` for you.
The general way to ask git to find `s` is to find the "merge base" between `HEAD` (`master`) and `feature`. The `git merge-base` command does this, so in a shell, you could do:
```
$ s=$(git merge-base HEAD feature)
```
and then
```
$ git diff $s feature
```
Conveniently, though, `git diff` takes over the three-dot syntax: `git diff X...Y` (note the three dots) means "find the merge-base of `X` and `Y` and then diff that merge-base against `Y`". So:
```
$ git diff master...feature
```
Or, since `HEAD` is currently a symbolic name for `master`, you can write:
```
$ git diff HEAD...feature
```
and this then means that you can simply write:
```
$ git diff ...feature
```
as omitting one of the names means "use `HEAD`". (Or, if you prefer and your git is not too ancient, you can use `@` to spell `HEAD`.) | If you want to see the changes from `s` to `feature`, then:
```
git diff s feature
```

] | *Debris* is broken-apart pieces of stuff arising from some sort of violent event that pulls things apart. (*Rubble* is a close synonym, although it carries more of a static feeling; we wouldn't usually say "rubble flying in the air," for example.) *Wreckage* is what's left of something identifiable that has been damaged beyond repair. *Remains* is also used in this context, but it is also used to refer to what's left of someone or something that has died, or a corpse. (We would not use *wreckage* to refer to such.)
A few pictures of tornado damage should clarify the differences.
This is a picture of flying debris from a tornado:
Here is a picture of a large piece of debris sticking through the wreckage of a car:

Here is the wreckage of a house and a truck after a tornado blew the truck into the house. As you can see, there is a fair amount of debris scattered about:

(e.g. the wreckage of a bus that has fallen over a small cliff).
**Debris** is from the French word *débris*, originally meaning to *break down*, and refers to many small pieces of wreckage or remains.
(e.g. the debris from a bus that had contained a terrorist bomb.)
**Remains** are what *remain* of something that has decayed, rotted, rusted, scavenged, etc. over a long time period (e.g. the remains of an abandoned bus). |

The properties in `data` are only reactive if they existed when the instance was created. That means if you add a new property, like:
```
myData.b = 12;
```
Then changes to `b` will not trigger any view updates. If you know you'll need a property later, but it starts out empty or non-existent, you'll need to set some initial value. For example:
```
let myData = { a: 1, b: 0 }
// or,
let myData = { a: 1, b: null }
```
Now you can see changes to `b` are showing in the UI also:
```js
let myData = { a: 1, b: 0 }
const app = new Vue({
el: "#myApp",
data: myData
})
myData.b = 12;

You **must** add a key to the root level object so you can update it later.
You can either:
* create a key with a default value that you'll update. This means that you know the key before hand
* create an empty object with a generic key (for instance `dynamicProps`) and use `Vue.set` to add dynamic keys at runtime to it. | >

hdsongs.txt and sdsongs.txt
I wrote a simple script to list all songs and output to text files, to then run a diff against.
It works fine for the most part, but the actual diff command in the script is showing the same line as being different. This is actually happening for multiple lines, but not all.
Here is an example of a song in both files:
```
$ grep Apologize \*songs\*
hdsongs.txt:Timbaland/Apologize.mp3
sdsongs.txt:Timbaland/Apologize.mp3

```
$ cat -A hdsongs.txt sdsongs.txt | grep Apologize
Timbaland/Apologize.mp3$

wait.connection().then(done);

});
```
Thank you for any response.
[EDIT]: Here there is the code I want to test:
```
var wait = {
connection: function()
{
'use strict';
var settings = {retry: 1000};
return new Promise(function(resolve)
{
(function poll()
{
needle.get('https://api.ipify.org', function(error, response)
{
if(!error && response.statusCode === 200 && /^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$|^(([a-zA-Z]|[a-zA-Z][a-zA-Z0-9\-]*[a-zA-Z0-9])\.)*([A-Za-z]|[A-Za-z][A-Za-z0-9\-]*[A-Za-z0-9])$|^\s*((([0-9A-Fa-f]{1,4}:){7}([0-9A-Fa-f]{1,4}|:))|(([0-9A-Fa-f]{1,4}:){6}(:[0-9A-Fa-f]{1,4}|((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3})|:))|(([0-9A-Fa-f]{1,4}:){5}(((:[0-9A-Fa-f]{1,4}){1,2})|:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3})|:))|(([0-9A-Fa-f]{1,4}:){4}(((:[0-9A-Fa-f]{1,4}){1,3})|((:[0-9A-Fa-f]{1,4})?:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(([0-9A-Fa-f]{1,4}:){3}(((:[0-9A-Fa-f]{1,4}){1,4})|((:[0-9A-Fa-f]{1,4}){0,2}:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(([0-9A-Fa-f]{1,4}:){2}(((:[0-9A-Fa-f]{1,4}){1,5})|((:[0-9A-Fa-f]{1,4}){0,3}:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(([0-9A-Fa-f]{1,4}:){1}(((:[0-9A-Fa-f]{1,4}){1,6})|((:[0-9A-Fa-f]{1,4}){0,4}:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(:(((:[0-9A-Fa-f]{1,4}){1,7})|((:[0-9A-Fa-f]{1,4}){0,5}:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:)))(%.+)?\s*$/.test(response.body))

In this case the Promise will remain pending since a new connection is available. How can I simulate an error on the `needle` get request? | 2016/04/29 | [

] | You can use [sinon](http://sinonjs.org/) to stub `needle.get`
```
var needle = require("needle");
var sinon = require("sinon");;
before(() => {
sinon.stub(needle, "get", (url, calback) => {
var dummyError = {};
callback(dummyError);
})
});
// Run your 'it' here
after(() => {
needle.get.restore();
});
``` | If you have no connection or any problems of connection, use the `reject()` of your promise and catch them. `done` is a function, and if you call the function with a non-null parameter, it means that your test is not good.
Maybe you have to try:
```
my_object.wait.connection()
.then(() => done(1))
.catch(() => done());
