I think that is a frequently asked question about the behavior of figures in beamer slides produced from Pandoc and markdown. The real problem is, R Markdown produces PNG images by default (from knitr), and it is hard to get the size of PNG images correct in LaTeX by default (I do not know why). It is fairly easy, however, to get the size of PDF images correct. One solution is to reset the default graphical device to PDF in your first chunk:

```{r setup, include=FALSE}
knitr::opts_chunk$set(dev = 'pdf')
```

Then all the images will be written as PDF files, and LaTeX will be happy.

Your second problem is you are mixing up the HTML units with LaTeX units in out.width / out.height. LaTeX and HTML are very different technologies. You should not expect \maxwidth to work in HTML, or 200px in LaTeX. Especially when you want to convert Markdown to LaTeX, you'd better not set out.width / out.height (use fig.width / fig.height and let LaTeX use the original size).

I have reformatted your slow sql query with www.prettysql.net

SELECT *
FROM some_table
WHERE
 relevant_field in
 (
  SELECT relevant_field
  FROM some_table
  GROUP BY relevant_field
  HAVING COUNT ( * ) > 1
 );

When using a table in both the query and the subquery, you should always alias both, like this:

SELECT *
FROM some_table as t1
WHERE
 t1.relevant_field in
 (
  SELECT t2.relevant_field
  FROM some_table as t2
  GROUP BY t2.relevant_field
  HAVING COUNT ( t2.relevant_field ) > 1
 );

Does that help?

A note for people who created the local copy on Windows and want to create a corresponding remote repository on a Unix-line system, where text files get LF endings on further clones by developers on Unix-like systems, but CRLF endings on Windows.

If you created your Windows repository before setting up line-ending translation then you have a problem. Git's default setting is no translation, so your working set uses CRLF but your repository (i.e. the data stored under .git) has saved the files as CRLF too.

When you push to the remote, the saved files are copied as-is, no line ending translation occurs. (Line ending translation occurs when files are commited to a repository, not when repositories are pushed). You end up with CRLF in your Unix-like repository, which is not what you want.

To get LF in the remote repository you have to make sure LF is in the local repository first, by re-normalizing your Windows repository. This will have no visible effect on your Windows working set, which still has CRLF endings, however when you push to remote, the remote will get LF correctly.

I'm not sure if there's an easy way to tell what line endings you have in your Windows repository - I guess you could test it by setting core.autocrlf=false and then cloning (If the repo has LF endings, the clone will have LF too).

Use .NET reflector.

Here is an idea as you may have multiple newline in a textbox:

 var text=document.getElementById('post-text').value.split('\n');
 var html = text.join('<br />');

This HTML value will preserve newline. Hope this helps.

Following are the results when we use both [MaxLength] and [StringLength] attributes, in EF code first. If both are used, [MaxLength] wins the race. See the test result in studentname column in below class

 public class Student
 {
    public Student () {}

    [Key]
    [Column(Order=1)]
    public int StudentKey { get; set; }

    //[MaxLength(50),StringLength(60)]    //studentname column will be nvarchar(50)
    //[StringLength(60)]    //studentname column will be nvarchar(60)
    [MaxLength(50)] //studentname column will be nvarchar(50)
    public string StudentName { get; set; }

    [Timestamp]
    public byte[] RowVersion { get; set; }
 }

plt.rcParams['figure.figsize'] = (15, 5)

BitmapFactory.decodeResource() automatically scales the bitmap, so your bitmap may turn out fuzzy. To prevent scaling, do this:

BitmapFactory.Options options = new BitmapFactory.Options();
options.inScaled = false;
Bitmap source = BitmapFactory.decodeResource(context.getResources(),
                                             R.drawable.resource_name, options);

or

InputStream is = context.getResources().openRawResource(R.drawable.resource_name)
bitmap = BitmapFactory.decodeStream(is);

Try this command

msiexec /x {product-id} /qr

SELECT DISTINCT city
FROM   station
WHERE  city RLIKE '^[^aeiouAEIOU]'OR city RLIKE'[^aeiouAEIOU]$'

I had the same problem.

This php setting solved my problem:

allow_url_fopen -> 1

Mehrdad makes some good points, but the main thing I noticed is that you never run the query...

SqlParameter retval = sqlcomm.Parameters.Add("@b", SqlDbType.VarChar);
retval.Direction = ParameterDirection.ReturnValue;
sqlcomm.ExecuteNonQuery(); // MISSING
string retunvalue = (string)sqlcomm.Parameters["@b"].Value;

I resolved the problem with this code:

HTML Form

<input type="checkbox" id="is-business" name="is-business" value="off" onclick="changeValueCheckbox(this)" >
<label for="is-business">Soy empresa</label>

and the javascript function by change the checkbox value form:

//change value of checkbox element
function changeValueCheckbox(element){
   if(element.checked){
    element.value='on';
  }else{
    element.value='off';
  }
}

and the server checked if the data post is "on" or "off". I used playframework java

        final Map<String, String[]> data = request().body().asFormUrlEncoded();

        if (data.get("is-business")[0].equals('on')) {
            login.setType(new MasterValue(Login.BUSINESS_TYPE));
        } else {
            login.setType(new MasterValue(Login.USER_TYPE));
        }

Reference on PHP net:

http://php.net/manual/en/info.configuration.php#ini.max-input-vars

Please note, you cannot set this directive in run-time with function ini_set(name, newValue), e.g.

ini_set('max_input_vars', 3000);

It will not work.

As explained in documentation, this directive may only be set per directory scope, which means via .htaccess file, httpd.conf or .user.ini (since PHP 5.3).

See http://php.net/manual/en/configuration.changes.modes.php

Adding the directive into php.ini or placing following lines into .htaccess will work:

php_value max_input_vars 3000
php_value suhosin.get.max_vars 3000
php_value suhosin.post.max_vars 3000
php_value suhosin.request.max_vars 3000

Try passing columns of the DataFrame directly to matplotlib, as in the examples below, instead of extracting them as numpy arrays.

df = pd.DataFrame(np.random.randn(10,2), columns=['col1','col2'])
df['col3'] = np.arange(len(df))**2 * 100 + 100

In [5]: df
Out[5]: 
       col1      col2  col3
0 -1.000075 -0.759910   100
1  0.510382  0.972615   200
2  1.872067 -0.731010   500
3  0.131612  1.075142  1000
4  1.497820  0.237024  1700

Vary scatter point size based on another column

plt.scatter(df.col1, df.col2, s=df.col3)
# OR (with pandas 0.13 and up)
df.plot(kind='scatter', x='col1', y='col2', s=df.col3)

Vary scatter point color based on another column

colors = np.where(df.col3 > 300, 'r', 'k')
plt.scatter(df.col1, df.col2, s=120, c=colors)
# OR (with pandas 0.13 and up)
df.plot(kind='scatter', x='col1', y='col2', s=120, c=colors)

Scatter plot with legend

However, the easiest way I've found to create a scatter plot with legend is to call plt.scatter once for each point type.

cond = df.col3 > 300
subset_a = df[cond].dropna()
subset_b = df[~cond].dropna()
plt.scatter(subset_a.col1, subset_a.col2, s=120, c='b', label='col3 > 300')
plt.scatter(subset_b.col1, subset_b.col2, s=60, c='r', label='col3 <= 300') 
plt.legend()

Update

From what I can tell, matplotlib simply skips points with NA x/y coordinates or NA style settings (e.g., color/size). To find points skipped due to NA, try the isnull method: df[df.col3.isnull()]

To split a list of points into many types, take a look at numpy select, which is a vectorized if-then-else implementation and accepts an optional default value. For example:

df['subset'] = np.select([df.col3 < 150, df.col3 < 400, df.col3 < 600],
                         [0, 1, 2], -1)
for color, label in zip('bgrm', [0, 1, 2, -1]):
    subset = df[df.subset == label]
    plt.scatter(subset.col1, subset.col2, s=120, c=color, label=str(label))
plt.legend()

For not looping this worked for me-
ReferenceLoopHandling = ReferenceLoopHandling.Ignore,

I've solved it all here - Entity Framework children serialization with .Net Core 2 WebAPI https://gist.github.com/Kaidanov/f9ad0d79238494432f32b8407942c606

Will appreciate any remarks. maybe someone can use it sometime.

As documented under CREATE TABLE Syntax:

Note
The older TYPE option was synonymous with ENGINE. TYPE was deprecated in MySQL 4.0 and removed in MySQL 5.5. When upgrading to MySQL 5.5 or later, you must convert existing applications that rely on TYPE to use ENGINE instead.

Therefore, you want:

CREATE TABLE dave_bannedwords(
  id   INT(11)     NOT NULL AUTO_INCREMENT,
  word VARCHAR(60) NOT NULL DEFAULT '',
  PRIMARY KEY (id),
  KEY id(id) -- this is superfluous in the presence of your PK, ergo unnecessary
) ENGINE = MyISAM ;

ECMAScript is a standard for JavaScript, look at these statements from MDN:

JavaScript

JavaScript (JS) is a lightweight interpreted or JIT-compiled programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as node.js, Apache CouchDB and Adobe Acrobat. JavaScript is a prototype-based, multi-paradigm, dynamic language, supporting object-oriented, imperative, and declarative (e.g. functional programming) styles. Read more about JavaScript.

ECMAScript

The standard for JavaScript is ECMAScript. As of 2012, all modern browsers fully support ECMAScript 5.1. Older browsers support at least ECMAScript 3. On June 17, 2015, ECMA International published the sixth major version of ECMAScript, which is officially called ECMAScript 2015, and was initially referred to as ECMAScript 6 or ES6. Since then, ECMAScript standards are on yearly release cycles. This documentation refers to the latest draft version, which is currently ECMAScript 2018.

You have 2 options, as described bellow:

Distribution package like Glaslos suggested:

# sudo apt-get install python-mysqldb

In this case you can't use virtualenv no-site-packages (default option) but must use:

# virtualenv --system-site-packages myenv

Use clean virtualenv and build your own python-mysql package.

First create virtualenv:

# virtualenv myvirtualenv
# source myvirtualenv/bin/activate

Then install build dependencies:

# sudo apt-get build-dep python-mysqldb

Now you can install python-mysql

# pip install mysql-python

NOTE Ubuntu package is python-mysql*db* , python pypi package is python-mysql (without db)

You can do it without dealing with encoding by using BlockCopy:

char[] chars = new char[bytes.Length / sizeof(char)];
System.Buffer.BlockCopy(bytes, 0, chars, 0, bytes.Length);
string str = new string(chars);

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

Update

There is a better write up if this is confusing people; check out finding documents and how queries work in the mongoose manual. If you want to use the fluent api you can get a query object by not providing a callback to the find() method, otherwise you can specify the parameters as I outline below.

Original

Given a model object, per the docs on Model, this is how it can work for 2.4.1:

Post.find({search-spec}, [return field array], {options}, callback)

The search spec expects an object, but you can pass null or an empty object.

The second param is the field list as an array of strings, so you would supply ['field','field2'] or null.

The third param is the options as an object, which includes the ability to sort the result set. You would use { sort: { field: direction } } where field is the string fieldname test (in your case) and direction is a number where 1 is ascending and -1 is desceding.

The final param (callback) is the callback function which receives the collection of docs returned by the query.

The Model.find() implementation (at this version) does a sliding allocation of properties to handle optional params (which is what confused me!):

Model.find = function find (conditions, fields, options, callback) {
  if ('function' == typeof conditions) {
    callback = conditions;
    conditions = {};
    fields = null;
    options = null;
  } else if ('function' == typeof fields) {
    callback = fields;
    fields = null;
    options = null;
  } else if ('function' == typeof options) {
    callback = options;
    options = null;
  }

  var query = new Query(conditions, options).select(fields).bind(this, 'find');

  if ('undefined' === typeof callback)
    return query;

  this._applyNamedScope(query);
  return query.find(callback);
};

HTH

$('#' + id).is(":checked")

That gets if the checkbox is checked.

For an array of checkboxes with the same name you can get the list of checked ones by:

var $boxes = $('input[name=thename]:checked');

Then to loop through them and see what's checked you can do:

$boxes.each(function(){
    // Do stuff here with this
});

To find how many are checked you can do:

$boxes.length;

personally I favor validating without a callback:

public bool ValidateSchema(string xmlPath, string xsdPath)
{
    XmlDocument xml = new XmlDocument();
    xml.Load(xmlPath);

    xml.Schemas.Add(null, xsdPath);

    try
    {
        xml.Validate(null);
    }
    catch (XmlSchemaValidationException)
    {
        return false;
    }
    return true;
}

(see Timiz0r's post in Synchronous XML Schema Validation? .NET 3.5)

Since this question is quite old, but still comes up in google searches, I thought it would be good to point out the newer (and recommended) way to save Keras models. Instead of saving them using the older h5 format like has been shown before, it is now advised to use the SavedModel format, which is actually a dictionary that contains both the model configuration and the weights.

More information can be found here: https://www.tensorflow.org/guide/keras/save_and_serialize

The snippets to save & load can be found below:

model.fit(test_input, test_target)
# Calling save('my_model') creates a SavedModel folder 'my_model'.
model.save('my_model')

# It can be used to reconstruct the model identically.
reconstructed_model = keras.models.load_model('my_model')

A sample output of this :

16 bit installer will not work on windows 7 it's no longer supported by win 7 the most recent supported version of windows that can run 16 bit installer is vista 32-bit even vista 64-bit doesn't support 16-bit installer.... reference http://support.microsoft.com/kb/946765

noexcept can dramatically improve performance of some operations. This does not happen at the level of generating machine code by the compiler, but by selecting the most effective algorithm: as others mentioned, you do this selection using function std::move_if_noexcept. For instance, the growth of std::vector (e.g., when we call reserve) must provide a strong exception-safety guarantee. If it knows that T's move constructor doesn't throw, it can just move every element. Otherwise it must copy all Ts. This has been described in detail in this post.

You can add any Git repository (or tarball) as a dependency to yarn by specifying the remote URL (either HTTPS or SSH):

yarn add <git remote url> installs a package from a remote git repository.
yarn add <git remote url>#<branch/commit/tag> installs a package from a remote git repository at specific git branch, git commit or git tag.
yarn add https://my-project.org/package.tgz installs a package from a remote gzipped tarball.

Here are some examples:

yarn add https://github.com/fancyapps/fancybox [remote url]
yarn add ssh://github.com/fancyapps/fancybox#3.0  [branch]
yarn add https://github.com/fancyapps/fancybox#5cda5b529ce3fb6c167a55d42ee5a316e921d95f [commit]

(Note: Fancybox v2.6.1 isn't available in the Git version.)

To support both npm and yarn, you can use the git+url syntax:

git+https://github.com/owner/package.git#commithashortagorbranch
git+ssh://github.com/owner/package.git#commithashortagorbranch

Today you can select elements with the same id attribute this way:

document.querySelectorAll('[id=test]');

Or this way with jQuery:

$('[id=test]');

CSS selector #test { ... } should work also for all elements with id = "test". ?ut the only thing: document.querySelectorAll('#test') (or $('#test') ) - will return only a first element with this id. Is it good, or not - I can't tell . But sometimes it is difficult to follow unique id standart .

For example you have the comment widget, with HTML-ids, and JS-code, working with these HTML-ids. Sooner or later you'll need to render this widget many times, to comment a different objects into a single page: and here the standart will broken (often there is no time or not allow - to rewrite built-in code).

You could do this:

NSNumberFormatter* f = [[NSNumberFormatter alloc] init];
[f setNumberStyle:NSNumberFormatterDecimalStyle];
[f setFormat:@0.00"];

// test
NSNumber* a = @12;
NSString* s = [f stringFromNumber:a];
NSLog(@"%@", s);

When I added IIS_IUSRS permission to site folder - resources, like js and css, still were unaccessible (error 401, forbidden). However, when I added IUSR - it became ok. So for sure "you CANNOT remove the permissions for IUSR without worrying", dear @Travis G@

(And if you have no admin access to the server)

ALTER ROLE <your_login_role> SET search_path TO a,b,c;

Two important things to know about:

1. When a schema name is not simple, it needs to be wrapped in double quotes.
2. The order in which you set default schemas a, b, c matters, as it is also the order in which the schemas will be looked up for tables. So if you have the same table name in more than one schema among the defaults, there will be no ambiguity, the server will always use the table from the first schema you specified for your search_path.

The size of the pointer may be something different than that of int. Also an implementation could produce better than simple hex value representation of the address when you use %p.

Determining of root cause is not an issue since Go 1.8; field name now is shown in the error message:

json: cannot unmarshal object into Go struct field Comment.author of type string

You have to add a shebang. A shebang is the first line of the file. Its what the system is looking for in order to execute a file.

It should look like that :

#!/usr/bin/env python

or the real path

#!/usr/bin/python

You should also check the file have the right to be execute. chmod +x file.py

As Fabian said, take a look to Wikipedia : Wikipedia - Shebang (en)

I have created function to disable previous date, disable flexible weekend days (Like Saturday, Sunday)

We are using beforeShowDay method of jQuery UI datepicker plugin.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
var NotBeforeToday = function(date) {_x000D_
  var now = new Date(); //this gets the current date and time_x000D_
  if (date.getFullYear() == now.getFullYear() && date.getMonth() == now.getMonth() && date.getDate() >= now.getDate() && (date.getDay() > 0 && date.getDay() < 6) )_x000D_
   return [true,""];_x000D_
  if (date.getFullYear() >= now.getFullYear() && date.getMonth() > now.getMonth() && (date.getDay() > 0 && date.getDay() < 6))_x000D_
   return [true,""];_x000D_

_x000D_
_x000D_
jQuery("#datepicker").datepicker({_x000D_
  beforeShowDay: NotBeforeToday_x000D_
    });

Here today's date is 15th Sept. I have disabled Saturday and Sunday.

For a bit of facts here is the relevant text from the specifications

Equality operator (==,!=)

Pointers to objects of the same type can be compared for equality with the 'intuitive' expected results:

From § 5.10 of the C++11 standard:

Pointers of the same type (after pointer conversions) can be compared for equality. Two pointers of the same type compare equal if and only if they are both null, both point to the same function, or both represent the same address (3.9.2).

(leaving out details on comparison of pointers to member and or the null pointer constants - they continue down the same line of 'Do What I Mean':)

• [...] If both operands are null, they compare equal. Otherwise if only one is null, they compare unequal.[...]

The most 'conspicuous' caveat has to do with virtuals, and it does seem to be the logical thing to expect too:

• [...] if either is a pointer to a virtual member function, the result is unspecified. Otherwise they compare equal if and only if they would refer to the same member of the same most derived object (1.8) or the same subobject if they were dereferenced with a hypothetical object of the associated class type. [...]

Relational operators (<,>,<=,>=)

From § 5.9 of the C++11 standard:

Pointers to objects or functions of the same type (after pointer conversions) can be compared, with a result defined as follows:

1. If two pointers p and q of the same type point to the same object or function, or both point one past the end of the same array, or are both null, then p<=q and p>=q both yield true and p<q and p>q both yield false.
2. If two pointers p and q of the same type point to different objects that are not members of the same object or elements of the same array or to different functions, or if only one of them is null, the results of p<q, p>q, p<=q, and p>=q are unspecified.
3. If two pointers point to non-static data members of the same object, or to subobjects or array elements of such members, recursively, the pointer to the later declared member compares greater provided the two members have the same access control (Clause 11) and provided their class is not a union.
4. If two pointers point to non-static data members of the same object with different access control (Clause 11) the result is unspecified.
5. If two pointers point to non-static data members of the same union object, they compare equal (after conversion to void*, if necessary). If two pointers point to elements of the same array or one beyond the end of the array, the pointer to the object with the higher subscript compares higher.
6. Other pointer comparisons are unspecified.

So, if you had:

int arr[3];
int *a = arr;
int *b = a + 1;
assert(a != b); // OK! well defined

Also OK:

struct X { int x,y; } s;
int *a = &s.x;
int *b = &s.y;
assert(b > a); // OK! well defined

But it depends on the something in your question:

int g; 
int main()
{
     int h;
     int i;

     int *a = &g;
     int *b = &h; // can't compare a <=> b
     int *c = &i; // can't compare b <=> c, or a <=> c etc.
     // but a==b, b!=c, a!=c etc. are supported just fine
}

Bonus: what else is there in the standard library?

§ 20.8.5/8: "For templates greater, less, greater_equal, and less_equal, the specializations for any pointer type yield a total order, even if the built-in operators <, >, <=, >= do not."

So, you can globally order any odd void* as long as you use std::less<> and friends, not bare operator<.

This should get you started: Using VBA in your own Excel workbook, have it prompt the user for the filename of their data file, then just copy that fixed range into your target workbook (that could be either the same workbook as your macro enabled one, or a third workbook). Here's a quick vba example of how that works:

' Get customer workbook...
Dim customerBook As Workbook
Dim filter As String
Dim caption As String
Dim customerFilename As String
Dim customerWorkbook As Workbook
Dim targetWorkbook As Workbook

' make weak assumption that active workbook is the target
Set targetWorkbook = Application.ActiveWorkbook

' get the customer workbook
filter = "Text files (*.xlsx),*.xlsx"
caption = "Please Select an input file "
customerFilename = Application.GetOpenFilename(filter, , caption)

Set customerWorkbook = Application.Workbooks.Open(customerFilename)

' assume range is A1 - C10 in sheet1
' copy data from customer to target workbook
Dim targetSheet As Worksheet
Set targetSheet = targetWorkbook.Worksheets(1)
Dim sourceSheet As Worksheet
Set sourceSheet = customerWorkbook.Worksheets(1)

targetSheet.Range("A1", "C10").Value = sourceSheet.Range("A1", "C10").Value

' Close customer workbook
customerWorkbook.Close

In addition to @Aleksandr Tukallo's answer, you could also obtain the output and error message (if occurs). Compressing a folder using tar is explained pretty well on the following answer.

import traceback
import subprocess

try:
    cmd = ['tar', 'czfj', output_filename, file_to_archive]
    output = subprocess.check_output(cmd).decode("utf-8").strip() 
    print(output)

Node.js itself offers an HTTP module, whose createServer method returns an object that you can use to respond to HTTP requests. That object inherits the http.Server prototype.

I also encounter with that problem. In my case the problem was that i closed the scanner inside one of the funcs..

public class Main _x000D_
{_x000D_
 public static void main(String[] args) _x000D_
 {_x000D_
  Scanner menu = new Scanner(System.in);_x000D_
        boolean exit = new Boolean(false);_x000D_
    while(!exit){_x000D_
  String choose = menu.nextLine();_x000D_
        Part1 t=new Part1()_x000D_
        t.start();_x000D_
     System.out.println("Noooooo Come back!!!"+choose);_x000D_
  }_x000D_
 menu.close();_x000D_
 }_x000D_
}_x000D_
_x000D_
public class Part1 extends Thread _x000D_
{_x000D_
public void run()_x000D_
  { _x000D_
     Scanner s = new Scanner(System.in);_x000D_
     String st = s.nextLine();_x000D_
     System.out.print("bllaaaaaaa\n"+st);_x000D_
     s.close();_x000D_
 }_x000D_
}_x000D_
_x000D_
   

The code above made the same exaption, the solution was to close the scanner only once at the main.

That's a very complex question for a simple answer.

You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.

Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.

• https://api.coinsecure.in/v1
• https://api.coinsecure.in/v1/originalUI
• https://api.coinsecure.in/v1/slateUI#!/Blockchain_Tools/v1_bitcoin_search_txid

At the very top level I think quality REST API docs require at least the following:

• a list of all your API endpoints (base/relative URLs)
• corresponding HTTP GET/POST/... method type for each endpoint
• request/response MIME-type (how to encode params and parse replies)
• a sample request/response, including HTTP headers
• type and format specified for all params, including those in the URL, body and headers
• a brief text description and important notes
• a short code snippet showing the use of the endpoint in popular web programming languages

Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.

The way to do this to take your nested target array and copy it in single step to a non-nested array. Delete the key(s) and then assign the final trimmed array to the nested node of the earlier array. Here is a code to make it simple:

$temp_array = $list['resultset'][0];

unset($temp_array['badkey1']);
unset($temp_array['badkey2']);

$list['resultset'][0] = $temp_array;

Yes, that is supported.

Check the documentation provided here for the supported keywords inside method names.

You can just define the method in the repository interface without using the @Query annotation and writing your custom query. In your case it would be as followed:

List<Inventory> findByIdIn(List<Long> ids);

I assume that you have the Inventory entity and the InventoryRepository interface. The code in your case should look like this:

The Entity

@Entity
public class Inventory implements Serializable {

  private static final long serialVersionUID = 1L;

  private Long id;

  // other fields
  // getters/setters

}

The Repository

@Repository
@Transactional
public interface InventoryRepository extends PagingAndSortingRepository<Inventory, Long> {

  List<Inventory> findByIdIn(List<Long> ids);

}

"Add a reference to MySql.Data.dll" means you need to add a library reference to the downloaded connector. The IDE will link the database connection library with your application when it compiles.

Step-by-Step Example

I downloaded the binary (no installer) zip package from the MySQL web site, extracted onto the desktop, and did the following:

1. Create a new project in Visual Studio
2. In the Solution Explorer, under the project name, locate References and right-click on it. Select "Add Reference".
3. In the "Add Reference" dialog, switch to the "Browse" tab and browse to the folder containing the downloaded connector. Navigate to the "bin" folder, and select the "MySql.Data.dll" file. Click OK.
4. At the top of your code, add using MySql.Data.MySqlClient;. If you've added the reference correctly, IntelliSense should offer to complete this for you.

This class tries to connect to min_gps_sat_count satellites if GPS is enabled. Else returns LocationManager.getBestProvider() location. Check the code!

I can't find anything that deals with clock times exactly, so I'd just use some functions from package:lubridate and work with seconds-since-midnight:

require(lubridate)
clockS = function(t){hour(t)*3600+minute(t)*60+second(t)}
plot(clockS(times),val)

You might then want to look at some of the axis code to figure out how to label axes nicely.

Unless there is a specific optimization that checks if the argument passed to removeAll() is the collection itself (and I highly doubt that such an optimization is there) it will be significantly slower than a simple .clear().

Apart from that (and at least equally important): arraylist.removeAll(arraylist) is just obtuse, confusing code. It is a very backwards way of saying "clear this collection". What advantage would it have over the very understandable arraylist.clear()?

Latest and greatest way to do this:

Node supports file and buffer operations with the base64 encoding:

const fs = require('fs');
const contents = fs.readFileSync('/path/to/file.jpg', {encoding: 'base64'});

Or using the new promises API:

const fs = require('fs').promises;
const contents = await fs.readFile('/path/to/file.jpg', {encoding: 'base64'});

onkeyup, onpaste, onchange, oninput seems to be failing when the browser performs autofill on the textboxes. To handle such a case include "autocomplete='off'" in your textfield to prevent browser from autofilling the textbox,

Eg,

<input id="inputDatabaseName" autocomplete='off' onchange="check();"
 onkeyup="this.onchange();" onpaste="this.onchange();" oninput="this.onchange();" />

<script>
     function check(){
          alert("Input box changed");
          // Things to do when the textbox changes
     }
</script>

This situation happens because you haven't installed/start service of ASP.net.

Use below command in windows 7,8,10.

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i

Another solution could be using jquery button selector inside the if else statement $("#buttonId").text("your text");

function showFilterItem() {
if (filterstatus == 0) {
    filterstatus = 1;
    $find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().showFilterItem();
    $("#ShowButton").text("Hide Filter");
}
else {
    filterstatus = 0;
    $find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().hideFilterItem();
     $("#ShowButton").text("Show Filter");
}}

In addition to the CheckedChangedEvent wiring one could use the Controls "Tag" property to distinguish between the radio buttons... an (spaghetti code) alternative would be the "TabIndex" property ;P

First, you need to add HttpHeaders with HttpClient

import { HttpClient,HttpHeaders  } from '@angular/common/http';

your constructor should be like this.

constructor(private http: HttpClient) { }

then you can use like this

   let header = new HttpHeaders({ "Authorization": "Bearer "+token});

   const requestOptions = {  headers: header};                                                                                                                                                                            

    return this.http.get<any>(url, requestOptions)
        .toPromise()
        .then(data=> {
            //...
            return data;
    });

if you use more thread ExecutionServices SEQUENTIALLY and want to wait EACH EXECUTIONSERVICE to be finished. The best way is like below;

ExecutorService executer1 = Executors.newFixedThreadPool(THREAD_SIZE1);
for (<loop>) {
   executer1.execute(new Runnable() {
            @Override
            public void run() {
                ...
            }
        });
} 
executer1.shutdown();

try{
   executer1.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);

   ExecutorService executer2 = Executors.newFixedThreadPool(THREAD_SIZE2);
   for (true) {
      executer2.execute(new Runnable() {
            @Override
            public void run() {
                 ...
            }
        });
   } 
   executer2.shutdown();
} catch (Exception e){
 ...
}

Your command line should have a -d/--data inserted before the string you want to send in the PUT, and you want to set the Content-Type and not Accept.

curl -H 'Content-Type: application/json' -X PUT -d '[JSON]' \
     http://example.com/service

Using the exact JSON data from the question, the full command line would become:

curl -H 'Content-Type: application/json' -X PUT \
    -d '{"tags":["tag1","tag2"],
         "question":"Which band?",
         "answers":[{"id":"a0","answer":"Answer1"},
                    {"id":"a1","answer":"answer2"}]}' \
    http://example.com/service

Note: JSON data wrapped only for readability, not valid for curl request.

I think you should try this

From php5.6 to php7.1

sudo a2dismod php5.6
sudo a2enmod php7.1
sudo service apache2 restart

sudo update-alternatives --set php /usr/bin/php7.1
sudo update-alternatives --set phar /usr/bin/phar7.1
sudo update-alternatives --set phar.phar /usr/bin/phar.phar7.1

From php7.1 to php5.6

sudo a2dismod php7.1
sudo a2enmod php5.6
sudo service apache2 restart

sudo update-alternatives --set php /usr/bin/php5.6
sudo update-alternatives --set phar /usr/bin/phar5.6

In order to build your repo after new commits, use Bitbucket Plugin.

There is just one thing to notice: When creating a POST Hook (notice that it is POST hook, not Jenkins hook), the URL works when it has a "/" in the end. Like:

URL: JENKINS_URL/bitbucket-hook/
e.g. someAddress:8080/bitbucket-hook/

Do not forget to check "Build when a change is pushed to Bitbucket" in your job configuration.

something like below

var idList=new int[]{1, 2, 3, 4};
using (var db=new SomeDatabaseContext())
{
    var friends= db.Friends.Where(f=>idList.Contains(f.ID)).ToList();
    friends.ForEach(a=>a.msgSentBy='1234');
    db.SaveChanges();
}

UPDATE:

you can update multiple fields as below

friends.ForEach(a =>
                      {
                         a.property1 = value1;
                         a.property2 = value2;
                      });

The options property contains all the <options> - from there you can look at .text

document.getElementById('test').options[0].text == 'Text One'

Zookeeper is a centralized open-source server for maintaining and managing configuration information, naming conventions and synchronization for distributed cluster environment. Zookeeper helps the distributed systems to reduce their management complexity by providing low latency and high availability. Zookeeper was initially a sub-project for Hadoop but now it's a top level independent project of Apache Software Foundation.

More Information

For file operations, Python uses the operating system's default buffering unless you configure it do otherwise. You can specify a buffer size, unbuffered, or line buffered.

For example, the open function takes a buffer size argument.

http://docs.python.org/library/functions.html#open

"The optional buffering argument specifies the file’s desired buffer size:"

• 0 means unbuffered,
• 1 means line buffered,
• any other positive value means use a buffer of (approximately) that size.
• A negative buffering means to use the system default, which is usually line buffered for tty devices and fully buffered for other files.
• If omitted, the system default is used.

code:

bufsize = 0
f = open('file.txt', 'w', buffering=bufsize)

Interestingly enough, very often len(unique()) is a few times (3x-15x) faster than nunique().

sometimes this error came beacause failed to compile in middlest of any build. The best way to try is by doing make clean and again make the whole code .

Try this:

$fruits = array( 4 => 'apple', 7 => 'orange', 13 => 'plum' );_x000D_
echo reset($fruits)."\n";

var myCallback = function(data) {
  console.log('got data: '+data);
};

var usingItNow = function(callback) {
  callback('get it?');
};

Now open node or browser console and paste the above definitions.

Finally use it with this next line:

usingItNow(myCallback);

With Respect to the Node-Style Error Conventions

Costa asked what this would look like if we were to honor the node error callback conventions.

In this convention, the callback should expect to receive at least one argument, the first argument, as an error. Optionally we will have one or more additional arguments, depending on the context. In this case, the context is our above example.

Here I rewrite our example in this convention.

var myCallback = function(err, data) {
  if (err) throw err; // Check for the error and throw if it exists.
  console.log('got data: '+data); // Otherwise proceed as usual.
};

var usingItNow = function(callback) {
  callback(null, 'get it?'); // I dont want to throw an error, so I pass null for the error argument
};

If we want to simulate an error case, we can define usingItNow like this

var usingItNow = function(callback) {
  var myError = new Error('My custom error!');
  callback(myError, 'get it?'); // I send my error as the first argument.
};

The final usage is exactly the same as in above:

usingItNow(myCallback);

The only difference in behavior would be contingent on which version of usingItNow you've defined: the one that feeds a "truthy value" (an Error object) to the callback for the first argument, or the one that feeds it null for the error argument.

In addition to all the other answers you received, I want to explain the unknown option -- o error: Your command was

$ adb shell 'su -c  mount -o rw,remount /system'

which calls su through adb. You properly quoted the whole su command in order to pass it as one argument to adb shell. However, su -c <cmd> also needs you to quote the command with arguments it shall pass to the shell's -c option. (YMMV depending on su variants.) Therefore, you might want to try

$ adb shell 'su -c "mount -o rw,remount /system"'

(and potentially add the actual device listed in the output of mount | grep system before the /system arg – see the other answers.)

If you'll check smaller than 10, you haven't to create a new function for that. Just assign a variable into brackets and return it with ternary operator.

(m = new Date().getMonth() + 1) < 10 ? `0${m}` : `${m}`

I used the first answer, but I felt was missing a recursion in it.

The result was this:

function dump(obj) {
    var out = '';
    for (var i in obj) {
        if(typeof obj[i] === 'object'){
            dump(obj[i]);
        }else{
            out += i + ": " + obj[i] + "\n";
        }
    }

    var pre = document.createElement('pre');
    pre.innerHTML = out;
    document.body.appendChild(pre);
}

The problem with most of these is that the user can still scroll up and see the addressbar. To make a permanent solution, you need to add this as well.

//WHENEVER the user scrolls
$(window).scroll(function(){
    //if you reach the top
    if ($(window).scrollTop() == 0)   
    //scroll back down  
    {window.scrollTo(1,1)}
})

XSLT 1.0 does not have an integer data type, only double. You can use number() to convert a string to a number.

If your using Visual Studio just run the application with Crtl + F5 instead of F5. This will leave the console open when it's finished executing.

app.manifest should be like this:

<?xml version="1.0" encoding="utf-8"?>
<asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <assemblyIdentity version="1.0.0.0" name="MyApplication.app" />
   <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">

         <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
            <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
         </requestedPrivileges>
      </security>
   </trustInfo>
</asmv1:assembly>

df.where(df.col("friend_id").isNull)

Another related tip is to use "%~1" instead of "%1". Type "CALL /?" at the command line in Windows to get more details.

You can also use 2 methods from java.time.YearMonth( Since Java 8 ):

import java.time.YearMonth;
...
int year = YearMonth.now().getYear();
int month = YearMonth.now().getMonthValue();

echo 0.0.0.0 websitename.com >> %WINDIR%\System32\Drivers\Etc\Hosts

the >> appends the output of echo to the file.

Note that there are two reasons this might not work like you want it to. You may be aware of these, but I mention them just in case.

First, it won't affect a web browser, for example, that already has the current, "real" IP address resolved. So, it won't always take effect right away.

Second, it requires you to add an entry for every host name on a domain; just adding websitename.com will not block www.websitename.com, for example.

Another way of saying it is that the i in your function is bound at the time of executing the function, not the time of creating the function.

When you create the closure, i is a reference to the variable defined in the outside scope, not a copy of it as it was when you created the closure. It will be evaluated at the time of execution.

Most of the other answers provide ways to work around by creating another variable that won't change the value for you.

Just thought I'd add an explanation for clarity. For a solution, personally, I'd go with Harto's since it is the most self-explanatory way of doing it from the answers here. Any of the code posted will work, but I'd opt for a closure factory over having to write a pile of comments to explain why I'm declaring a new variable(Freddy and 1800's) or have weird embedded closure syntax(apphacker).

Here is how do it with single statement

WITH deleted_rows AS (
DELETE FROM source_table WHERE id = 1
RETURNING *
) 
INSERT INTO destination_table 
SELECT * FROM deleted_rows;

EXAMPLE:

    postgres=# select * from test1 ;
 id |  name
----+--------
  1 | yogesh
  2 | Raunak
  3 | Varun
(3 rows)


postgres=# select * from test2;
 id | name
----+------
(0 rows)


postgres=# WITH deleted_rows AS (
postgres(# DELETE FROM test1 WHERE id = 1
postgres(# RETURNING *
postgres(# )
postgres-# INSERT INTO test2
postgres-# SELECT * FROM deleted_rows;
INSERT 0 1


postgres=# select * from test2;
 id |  name
----+--------
  1 | yogesh
(1 row)

postgres=# select * from test1;
 id |  name
----+--------
  2 | Raunak
  3 | Varun

Now you can use device file explorer instead of device monitor. Go to

view > tool windows > device file explorer

screenshot: opening device file explorer in android studio 3.1.3

More details

1. Click View > Tool Windows > Device File Explorer or click the Device File Explorer button in the tool window bar to open the Device File Explorer.
2. Select a device from the drop down list.
3. Interact with the device content in the file explorer window. Right-click on a file or directory to create a new file or directory, save the selected file or directory to your machine, upload, delete, or synchronize. Double-click a file to open it in Android Studio.

Android Studio saves files you open this way in a temporary directory outside of your project. If you make modifications to a file you opened using the Device File Explorer, and would like to save your changes back to the device, you must manually upload the modified version of the file to the device.

screenshot: The Device File Explorer tool window

When exploring a device's files, the following directories are particularly useful:

data/data/app_name/

Contains data files for your app stored on internal storage

sdcard/

Contains user files stored on external user storage (pictures, etc.)

Note: Not all files on a hardware device are visible in the Device File Explorer. For example, in the data/data/ directory, entries corresponding to apps on the device that are not debuggable cannot be expanded in the Device File Explorer.

If you wanted to stay with a class level selector then you could do something like this (using the same jfiddle from Mahn)

$("div.fetch_results input:text").each(function() {
  this.value = "testing";
})?

This will select only the text input boxes within the div with a fetch_results class.

As with any jQuery this is just one way to do it. Ask 10 jQuery people this question and you will get 12 answers.

Just to simplify the example of Tyler.

test:-prefix is not needed.

So according to his example:

In the sbt-console:

testOnly *LoginServiceSpec

And in the terminal:

sbt "testOnly *LoginServiceSpec"

For anyone still reading this: setTargetFragment() has been deprecated. It is now recommended to use the FragmentResultListener API like this:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setFragmentResultListener("requestKey") { key, bundle ->
        val result = bundle.getString("resultKey")
        // Do something with the result...
    }

    ...

    // Somewhere show your dialog
    MyDialogFragment.newInstance().show(parentFragmentManager, "tag")
}

Then in your MyDialogFragment set the result:

button.setOnClickListener{
    val result = "some string"
    setFragmentResult("requestKey", bundleOf("resultKey" to result))
    dismiss()
}

Using a collection initializer

From C# 3, you can use collection initializers to construct a List and populate it using a single expression. The following example constructs a Human and its ContactNumbers:

var human = new Human(1, "Address", "Name") {
    ContactNumbers = new List<ContactNumber>() {
        new ContactNumber(1),
        new ContactNumber(2),
        new ContactNumber(3)
    }
}

Specializing the Human constructor

You can change the constructor of the Human class to provide a way to populate the ContactNumbers property:

public class Human
{
    public Human(int id, string address, string name, IEnumerable<ContactNumber> contactNumbers) : this(id, address, name)
    {
        ContactNumbers = new List<ContactNumber>(contactNumbers);
    }

    public Human(int id, string address, string name, params ContactNumber[] contactNumbers) : this(id, address, name)
    {
        ContactNumbers = new List<ContactNumber>(contactNumbers);
    }
}

// Using the first constructor:
List<ContactNumber> numbers = List<ContactNumber>() {
    new ContactNumber(1),
    new ContactNumber(2),
    new ContactNumber(3)
};

var human = new Human(1, "Address", "Name", numbers);

// Using the second constructor:
var human = new Human(1, "Address", "Name",
    new ContactNumber(1),
    new ContactNumber(2),
    new ContactNumber(3)
);

Bottom line

Which alternative is a best practice? Or at least a good practice? You judge it! IMO, the best practice is to write the program as clearly as possible to anyone who has to read it. Using the collection initializer is a winner for me, in this case. With much less code, it can do almost the same things as the alternatives -- at least, the alternatives I gave...

You can use below class to schedule your task every day particular time

package interfaces;

import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.temporal.ChronoUnit;
import java.util.Date;
import java.util.concurrent.Executors;
import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.TimeUnit;

public class CronDemo implements Runnable{

    public static void main(String[] args) {

        Long delayTime;

        ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(1);

        final Long initialDelay = LocalDateTime.now().until(LocalDate.now().plusDays(1).atTime(12, 30), ChronoUnit.MINUTES);

        if (initialDelay > TimeUnit.DAYS.toMinutes(1)) {
            delayTime = LocalDateTime.now().until(LocalDate.now().atTime(12, 30), ChronoUnit.MINUTES);
        } else {
            delayTime = initialDelay;
        }

        scheduler.scheduleAtFixedRate(new CronDemo(), delayTime, TimeUnit.DAYS.toMinutes(1), TimeUnit.MINUTES);

    }

    @Override
    public void run() {
        System.out.println("I am your job executin at:" + new Date());
    }
}

Avoid hardcoding try making the code that is dynamic below is the code it will work for any xml I have used SAX Parser you can use dom,xpath it's upto you I am storing all the tags name and values in the map after that it becomes easy to retrieve any values you want I hope this helps
SAMPLE XML:

<parent>
<child >
    <child1> value 1 </child1>
    <child2> value 2 </child2>
    <child3> value 3 </child3>
    </child>
    <child >
     <child4> value 4 </child4>
    <child5> value 5</child5>
    <child6> value 6 </child6>
    </child>
  </parent>

I don't believe the currently accepted answer is correct. For example, I have the following .htaccess file in the root of a virtual server (apache 2.4):

<Files "reminder.php">
require all denied
require host localhost
require ip 127.0.0.1
require ip xxx.yyy.zzz.aaa
</Files>

This prevents external access to reminder.php which is in a subdirectory. I have a similar .htaccess file on my Apache 2.2 server with the same effect:

<Files "reminder.php">
        Order Deny,Allow
        Deny from all
        Allow from localhost
        Allow from 127.0.0.1
     Allow from xxx.yyy.zzz.aaa
</Files>

I don't know for sure but I suspect it's the attempt to define the subdirectory specifically in the .htaccess file, viz <Files ./inscription/log.txt> which is causing it to fail. It would be simpler to put the .htaccess file in the same directory as log.txt i.e. in the inscription directory and it will work there.

The @ operator calls the array's __matmul__ method, not dot. This method is also present in the API as the function np.matmul.

>>> a = np.random.rand(8,13,13)
>>> b = np.random.rand(8,13,13)
>>> np.matmul(a, b).shape
(8, 13, 13)

From the documentation:

matmul differs from dot in two important ways.

• Multiplication by scalars is not allowed.
• Stacks of matrices are broadcast together as if the matrices were elements.

The last point makes it clear that dot and matmul methods behave differently when passed 3D (or higher dimensional) arrays. Quoting from the documentation some more:

For matmul:

If either argument is N-D, N > 2, it is treated as a stack of matrices residing in the last two indexes and broadcast accordingly.

For np.dot:

For 2-D arrays it is equivalent to matrix multiplication, and for 1-D arrays to inner product of vectors (without complex conjugation). For N dimensions it is a sum product over the last axis of a and the second-to-last of b

You can use preg_replace in this case;

$res = preg_replace("/[^0-9]/", "", "Every 6 Months" );

$res return 6 in this case.

If want also to include decimal separator or thousand separator check this example:

$res = preg_replace("/[^0-9.]/", "", "$ 123.099");

$res returns "123.099" in this case

Include period as decimal separator or thousand separator: "/[^0-9.]/"

Include coma as decimal separator or thousand separator: "/[^0-9,]/"

Include period and coma as decimal separator and thousand separator: "/[^0-9,.]/"

The above were really close. Here's my solution:

Private Sub getDsClone(ByRef inClone As DataSet, ByVal matchStr As String, ByRef outClone As DataSet)
    Dim i As Integer

    outClone = inClone.Clone
    Dim dv As DataView = inClone.Tables(0).DefaultView
    dv.RowFilter = matchStr
    Dim dt As New DataTable
    dt = dv.ToTable
    For i = 0 To dv.Count - 1
        outClone.Tables(0).ImportRow(dv.Item(i).Row)
    Next
End Sub

"::" represents scope resolution operator. Functions/methods which have same name can be defined in two different classes. To access the methods of a particular class scope resolution operator is used.

Check current scrollTop vs previous scrollTop

var lastScrollTop = 0;
$(window).scroll(function(event){
   var st = $(this).scrollTop();
   if (st > lastScrollTop){
       // downscroll code
   } else {
      // upscroll code
   }
   lastScrollTop = st;
});

Playing with JavaScript in an HTA I had no luck with a driver={SQL Server};... connection string, but a named DSN was OK :
I set up TestDSN and it tested OK, and then var strConn= "DSN=TestDSN"; worked, so I carried on experimenting for my in-house testing and learning purposes.

Our server has several instances running, e.g. server1\dev and server1\Test which made things slightly more tricky as I managed to waste some time forgetting to escape the \ as \\ :)
After some dead-ends with server=server1;instanceName=dev in the connection strings, I eventually got this one to work :
var strConn= "Provider=SQLOLEDB;Data Source=server1\\dev;Trusted_Connection=Yes;Initial Catalog=MyDatabase;"

Using Windows credentials rather than supplying a user/pwd, I found an interesting diversion was discovering the subtleties of Integrated Security = true v Integrated Security = SSPI v Trusted_Connection=Yes - see Difference between Integrated Security = True and Integrated Security = SSPI

Beware that RecordCount will come back as -1 if using the default adOpenForwardOnly type. If you're working with small result sets and/or don't mind the whole lot in memory at once, use rs.Open(strQuery, objConnection, 3); (3=adOpenStatic) and this gives a valid rs.RecordCount

In your terminal/console (only Linux, in windows you need Putty)

ssh user@ip
php -i | grep "Loaded Configuration File"

And it will show you something like this Loaded Configuration File => /etc/php.ini.

ALTERNATIVE METHOD

You can make a php file on your website, which run: <?php phpinfo(); ?>, and you can see the php.ini location on the line with: "Loaded Configuration File".

Update This command gives the path right away

document.write() doesn't work with XHTML. It's executed after the page has finished loading and does nothing more than write out a string of HTML.

Since the actual in-memory representation of HTML is the DOM, the best way to update a given page is to manipulate the DOM directly.

The way you'd go about doing this would be to programmatically create your nodes and then attach them to an existing place in the DOM. For [purposes of a contrived] example, assuming that I've got a div element maintaining an ID attribute of "header," then I could introduce some dynamic text by doing this:

// create my text
var sHeader = document.createTextNode('Hello world!');

// create an element for the text and append it
var spanHeader = document.createElement('span');
spanHeader.appendChild(sHeader);

// grab a reference to the div header
var divHeader = document.getElementById('header');

// append the new element to the header
divHeader.appendChild(spanHeader);

Your best bet will be looking at the WifiManager class. Specifically the setWifiEnabled(bool) function.

See the documentation at: http://developer.android.com/reference/android/net/wifi/WifiManager.html#setWifiEnabled(boolean)

A tutorial on how to use it (including what permissions you need) can be found here: http://www.tutorialforandroid.com/2009/10/turn-off-turn-on-wifi-in-android-using.html

You seem close.

I would try to set the URI like this :

String folderPath = Environment.getExternalStorageDirectory()+"/pathTo/folder";

Intent intent = new Intent();  
intent.setAction(Intent.ACTION_GET_CONTENT);
Uri myUri = Uri.parse(folderPath);
intent.setDataAndType(myUri , "file/*");   
startActivity(intent);

But it's not so different from what you have tried. Tell us if it changes anything ?

Also make sure the targeted folder exists, and have a look on the resulting Uri object before to send it to the intent, it may not be what we are expected.

I run an SP to DROP the table(s) and then use a DTS package to import the most recent production table(s) onto my development box. Then I go home and come back the following morning. It's not elegant; but it works for me.

In Windows when a process terminates, the OS closes the associated window. This happens with all programs (and is generally desirable behaviour), but people never cease to be surprised when it happens to the ones they write themselves.

I am being slightly harsh perhaps; many IDE's execute the user's process in a shell as a child process, so that it does not own the window so it won't close when the process terminates. Although this would be trivial, Dev-C++ does not do that.

Be aware that when Dev-C++ was popular, this question appeard at least twice a day on Dev-C++'s own forum on Sourceforge. For that reason the forum has a "Read First" thread that provides a suggested solution amongst solutions to many other common problems. You should read it here.

Note that Dev-C++ is somewhat old and no longer actively maintained. It suffers most significantly from an almost unusable and very limited debugger integration. Traffic on the Dev-C++ forum has been dropping off since the release of VC++ 2005 Express, and is now down to a two or three posts a week rather than the 10 or so a day it had in 2005. All this suggest that you should consider an alternative tool IMO.

The browser support status is this:

IE8, Firefox, Opera: $("html")

Chrome, Safari: $("body")

So this works:

bodyelem = $.browser.safari ? $("body") : $("html") ;
bodyelem.animate( {scrollTop: 0}, 500 );

Only methods with WebGet can be accessed from browser IE ; you can access other http verbs by just typing address

You can either try Restful service startup kit of codeples or use fiddler to test your other http verbs

As the recent developed Web Applications are using JavaScript, jQuery, AngularJS, ReactJS etc there is a possibility that to retrieve an attribute of an element through Selenium you have to induce WebDriverWait to synchronize the WebDriver instance with the lagging Web Client i.e. the Web Browser before trying to retrieve any of the attributes.

Some examples:

• Python:

  • To retrieve any attribute form a visible element (e.g. <h1> tag) you need to use the expected_conditions as visibility_of_element_located(locator) as follows:

    attribute_value = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.ID, "org"))).get_attribute("attribute_name")
    

  • To retrieve any attribute form an interactive element (e.g. <input> tag) you need to use the expected_conditions as element_to_be_clickable(locator) as follows:

    attribute_value = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, "org"))).get_attribute("attribute_name")
    

HTML Attributes

Below is a list of some attributes often used in HTML

Note: A complete list of all attributes for each HTML element, is listed in: HTML Attribute Reference

I did some test to see how the theory actually works: kennethxu.blogspot.com/2009/05/interlocked-vs-monitor-performance.html. My test was more focused on CompareExchnage but the result for Increment is similar. Interlocked is not necessary faster in multi-cpu environment. Here is the test result for Increment on a 2 years old 16 CPU server. Bare in mind that the test also involves the safe read after increase, which is typical in real world.

First of all be sure to add this line in manifest tag

Then add tools replace your suggested one in Android studio

You can get around this even more easily with the Rebase extension, just use hg pull --rebase and your commits are automatically re-comitted to the pulled revision, avoiding the branching issue.

1. literal_eval, a somewhat safer version of eval (will only evaluate literals ie strings, lists etc):

   from ast import literal_eval
   
   python_dict = literal_eval("{'a': 1}")
   

2. json.loads but it would require your string to use double quotes:

   import json
   
   python_dict = json.loads('{"a": 1}')
   

Enter command mode and run

:r! sed -n '<start_line_num>, <end_line_num> p' file_to_extract_text_from

E.g to extract lines 20-30 from filename into the currently opened file

:r! sed -n '20, 30p' filename

If --grace-period=0 is not working then you can do:

kubectl delete pods <pod> --grace-period=0 --force

I would just not add it in the first place:

 var sb = new StringBuilder();

 bool first = true;
 foreach (var foo in items) {
    if (first)
        first = false;
    else
        sb.Append('&');

    // for example:
    var escapedValue = System.Web.HttpUtility.UrlEncode(foo);

    sb.Append(key).Append('=').Append(escapedValue);
 }

 var s = sb.ToString();

I know that's an old one question, but its high in the search results.

If anyone wants timestamp conversion directly to a DateTime object, there's a simple one-liner:

$timestamp = 1299446702;
$date = DateTime::createFromFormat('U', $timestamp);

Following @sromero comment, timezone parameter (the 3rd param in DateTime::createFromFormat()) is ignored when unix timestamp is passed, so the below code is unnecessary.

$date = DateTime::createFromFormat('U', $timestamp, new DateTimeZone('UTC'); // not needed, 3rd parameter is ignored

You may check PHP's manual for DateTime::createFromFormat for more info and options.

Another alternative can be to execute the Keydown or KeyUp in the tag of the Form

<form name="nameForm" [formGroup]="groupForm" (keydown.enter)="executeFunction()" >

Here is a different solution, that also allows the replacement of a single group in multiple matches. It uses stacks to reverse the execution order, so the string operation can be safely executed.

private static void demo () {

    final String sourceString = "hello world!";

    final String regex = "(hello) (world)(!)";
    final Pattern pattern = Pattern.compile(regex);

    String result = replaceTextOfMatchGroup(sourceString, pattern, 2, world -> world.toUpperCase());
    System.out.println(result);  // output: hello WORLD!
}

public static String replaceTextOfMatchGroup(String sourceString, Pattern pattern, int groupToReplace, Function<String,String> replaceStrategy) {
    Stack<Integer> startPositions = new Stack<>();
    Stack<Integer> endPositions = new Stack<>();
    Matcher matcher = pattern.matcher(sourceString);

    while (matcher.find()) {
        startPositions.push(matcher.start(groupToReplace));
        endPositions.push(matcher.end(groupToReplace));
    }
    StringBuilder sb = new StringBuilder(sourceString);
    while (! startPositions.isEmpty()) {
        int start = startPositions.pop();
        int end = endPositions.pop();
        if (start >= 0 && end >= 0) {
            sb.replace(start, end, replaceStrategy.apply(sourceString.substring(start, end)));
        }
    }
    return sb.toString();       
}

First of all, you should be using json.loads, not json.dumps. loads converts JSON source text to a Python value, while dumps goes the other way.

After you fix that, based on the JSON snippet at the top of your question, readable_json will be a list, and so readable_json['firstName'] is meaningless. The correct way to get the 'firstName' field of every element of a list is to eliminate the playerstuff = readable_json['firstName'] line and change for i in playerstuff: to for i in readable_json:.

Indeed, if you perform some complex calculations inside the loop, then the performance of the array indexer versus the list indexer may be so marginally small, that eventually, it doesn't matter.

Some of the solutions described here did not work for me. Others did, however they produced warnings on runtime and javadoc was still not linked. After some experimenting, I managed to solve this. The steps are:

1. Install the Google Play Services as recommended on Android Developers.

2. Set up your project as recommended on Android Developers.

3. If you followed 1. and 2., you should see two projects in your workspace: your project and google-play-services_lib project. Copy the docs folder which contains the javadoc from <android-sdk>/extras/google/google_play_services/ to libs folder of your project.

4. Copy google-play-services.jar from <android-sdk>/extras/google/google_play_services/libproject/google-play-services_lib/libs to 'libs' folder of your project.

5. In google-play-services_lib project, edit libs/google-play-services.jar.properties . The <path> in doc=<path> should point to the subfolder reference of the folder docs, which you created in step 3.

6. In Eclipse, do Project > Clean. Done, javadoc is now linked.

If you're going to call a python script from some other process (say, from the command line), use pythonw.exe. Otherwise, your user will continuously see a cmd window launching the python process. It'll still run your script just the same, but it won't intrude on the user experience.

An example might be sending an email; python.exe will pop up a CLI window, send the email, then close the window. It'll appear as a quick flash, and can be considered somewhat annoying. pythonw.exe avoids this, but still sends the email.

Use getName() as the key and Choice itself as the value of the map:

Map<String, Choice> result =
    choices.stream().collect(Collectors.toMap(Choice::getName, c -> c));

Just for the record, here is the difference between If and IIf:

IIf(condition, true-part, false-part):

• This is the old VB6/VBA Function
• The function always returns an Object type, so if you want to use the methods or properties of the chosen object, you have to re-cast it with DirectCast or CType or the Convert.* Functions to its original type
• Because of this, if true-part and false-part are of different types there is no matter, the result is just an object anyway

If(condition, true-part, false-part):

• This is the new VB.NET Function
• The result type is the type of the chosen part, true-part or false-part
• This doesn't work, if Strict Mode is switched on and the two parts are of different types. In Strict Mode they have to be of the same type, otherwise you will get an Exception
• If you really need to have two parts of different types, switch off Strict Mode (or use IIf)
• I didn't try so far if Strict Mode allows objects of different type but inherited from the same base or implementing the same Interface. The Microsoft documentation isn't quite helpful about this issue. Maybe somebody here knows it.

I think most solutions talk here about List Comprehension, but if you'd like to perform in place deletion and keep the space complexity to O(1); The solution is:

i = 0
for j in range(len(arr)):
if (arr[j] != 0):
    arr[i] = arr[j]
    i +=1
arr = arr[:i] 

fromEvent<KeyboardEvent>(document.querySelector('#searcha') as HTMLInputElement , 'keyup')

      debounceTime(500),
      distinctUntilChanged(),
      map(e  => {
            return e.target['value']; // <-- target does not exist on {}
        })
    ).subscribe(k => console.log(k));

Maybe something like the above could help. Change it based on the real code. The issue is ........ target['value']

The new fontawesome (version 4.0.3) makes this really easy to do. We simply use the following classes:

<ul class="fa-ul">
  <li><i class="fa-li fa fa-check-square"></i>List icons (like these)</li>
  <li><i class="fa-li fa fa-check-square"></i>can be used</li>
  <li><i class="fa-li fa fa-spinner fa-spin"></i>to replace</li>
  <li><i class="fa-li fa fa-square"></i>default bullets in lists</li>
</ul>

To add to @migontech's answer and also his address his comment that you could "probably make it more generic", here's a way to do it. The below will allow you to search by any property:

.filter('getByProperty', function() {
    return function(propertyName, propertyValue, collection) {
        var i=0, len=collection.length;
        for (; i<len; i++) {
            if (collection[i][propertyName] == +propertyValue) {
                return collection[i];
            }
        }
        return null;
    }
});

The call to filter would then become:

var found = $filter('getByProperty')('id', fish_id, $scope.fish);

Note, I removed the unary(+) operator to allow for string-based matches...

recyclerView.addOnItemTouchListener(object : AdapterView.OnItemClickListener,
                RecyclerView.OnItemTouchListener {
                override fun onItemClick(p0: AdapterView<*>?, p1: View?, p2: Int, p3: Long) {
                    TODO("Not yet implemented")

                override fun onTouchEvent(rv: RecyclerView, e: MotionEvent) {

                }

                override fun onInterceptTouchEvent(rv: RecyclerView, e: MotionEvent): Boolean {
                    TODO("Not yet implemented")
                }

                override fun onRequestDisallowInterceptTouchEvent(disallowIntercept: Boolean) {

I came across ParamUnittest the other day when looking at the source code for radon (example usage on the GitHub repository). It should work with other frameworks that extend TestCase (like Nose).

Here is an example:

import unittest
import paramunittest


@paramunittest.parametrized(
    ('1', '2'),
    #(4, 3),    <---- Uncomment to have a failing test
    ('2', '3'),
    (('4', ), {'b': '5'}),
    ((), {'a': 5, 'b': 6}),
    {'a': 5, 'b': 6},
)
class TestBar(TestCase):
    def setParameters(self, a, b):
        self.a = a
        self.b = b

    def testLess(self):
        self.assertLess(self.a, self.b)

A more reliable REST endpoint would be http://freegeoip.net/json/

it is the same thing as above except somehow it is neater the zip does the work but requires single arrays as arguments, the *a syntax unpacks the multidimensional array into single array arguments

A View object is a component of the user interface (UI) like a button or a text box, and it's also called widget.

A ViewGroup object is a layout, that is, a container of other ViewGroup objects (layouts) and View objects (widgets). It's possible to have a layout inside another layout. It's called nested layout but it can increase the time needed to draw the user interface.

The user interface for an app is built using a hierarchy of ViewGroup and View objects. In Android Studio it is possible to use the Component Tree window to visualise this hierarchy.

The Layout Editor in Android Studio can be used to drag and drop View objects (widgets) in the layout. It simplifies the creation of a layout.

response = requests.get(url)
filename.write_bytes(response.content)

If a website's directory does NOT have an "index...." file, AND .htaccess has NOT been used to block access to the directory itself, then Apache will create an "index of" page for that directory. You can save that page, and its icons, using "Save page as..." along with the "Web page, complete" option (Firefox example). If you own the website, temporarily rename any "index...." file, and reference the directory locally. Then restore your "index...." file.

and the fix was opening the script in a hex editor and removing the first 3 characters from the file. The file was starting with an UTF-8 BOM and it seems that Rscript can't read that.

EDIT: OP requested an example. Here it goes.

?  ~ cat a.R
cat('hello world\n')
?  ~ xxd a.R
00000000: efbb bf63 6174 2827 6865 6c6c 6f20 776f  ...cat('hello wo
00000010: 726c 645c 6e27 290a                      rld\n').
?  ~ R -f a.R

Enable CORS in the WebService app. First, add the CORS NuGet package. In Visual Studio, from the Tools menu, select NuGet Package Manager, then select Package Manager Console. In the Package Manager Console window, type the following command:

Install-Package Microsoft.AspNet.WebApi.Cors

This command installs the latest package and updates all dependencies, including the core Web API libraries. Use the -Version flag to target a specific version. The CORS package requires Web API 2.0 or later.

Open the file App_Start/WebApiConfig.cs. Add the following code to the WebApiConfig.Register method:

using System.Web.Http;
namespace WebService
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // New code
            config.EnableCors();

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
        }
    }
}

Next, add the [EnableCors] attribute to your controller/ controller methods

using System.Net.Http;
using System.Web.Http;
using System.Web.Http.Cors;

namespace WebService.Controllers
{
    [EnableCors(origins: "http://mywebclient.azurewebsites.net", headers: "*", methods: "*")]
    public class TestController : ApiController
    {
        // Controller methods not shown...
    }
}

To handle the possibility of int, float, and empty string values, I'd use a combination of a list comprehension, dictionary comprehension, along with conditional expressions, as shown:

dicts = [{'a': '1' , 'b': '' , 'c': '3.14159'},
         {'d': '4' , 'e': '5' , 'f': '6'}]

print [{k: int(v) if v and '.' not in v else float(v) if v else None
            for k, v in d.iteritems()}
               for d in dicts]

# [{'a': 1, 'c': 3.14159, 'b': None}, {'e': 5, 'd': 4, 'f': 6}]

However dictionary comprehensions weren't added to Python 2 until version 2.7. It can still be done in earlier versions as a single expression, but has to be written using the dict constructor like the following:

# for pre-Python 2.7

print [dict([k, int(v) if v and '.' not in v else float(v) if v else None]
            for k, v in d.iteritems())
                for d in dicts]

# [{'a': 1, 'c': 3.14159, 'b': None}, {'e': 5, 'd': 4, 'f': 6}]

Note that either way this creates a new dictionary of lists, instead of modifying the original one in-place (which would need to be done differently).

To add color to an input, Use the following css code:

input{
     color: black;
}

I did debugging and finally returned my 'stuffed' query to it it's normal way.

Simply

select * from myTable for xml path('myTable')

gives me contents of the table to write to a log table from a trigger I debug.

I just came across this error, and here's what I found out in case this helps anyone: I discovered that you can right click the error message in Xcode and choose expand to get more details, including a description of the problem.

In my case, I had two copies of my developer certificate with the same name in different keychain files, and Xcode couldn't figure out which one to use.

A simple solution without using external modules:

from datetime import datetime, timezone

dt = datetime(2008, 1, 1, 0, 0, 0, 0)
int(dt.replace(tzinfo=timezone.utc).timestamp())

Use numpy.apply_along_axis(). Assuming your matrix is 2D, you can use like:

import numpy as np
mymatrix = np.matrix([[11,12,13],
                      [21,22,23],
                      [31,32,33]])
def myfunction( x ):
    return sum(x)

print np.apply_along_axis( myfunction, axis=1, arr=mymatrix )
#[36 66 96]

You can kill two birds with one regex stone:

>>> r = """
... \n\tName: John Smith
... \n\t  Home: Anytown USA
... \n\t    Phone: 555-555-555
... \n\t  Other Home: Somewhere Else
... \n\t Notes: Other data
... \n\tName: Jane Smith
... \n\t  Misc: Data with spaces
... """
>>> import re
>>> print re.findall(r'(\S[^:]+):\s*(.*\S)', r)
[('Name', 'John Smith'), ('Home', 'Anytown USA'), ('Phone', '555-555-555'), ('Other Home', 'Somewhere Else'), ('Notes', 'Other data'), ('Name', 'Jane Smith'), ('Misc', 'Data with spaces')]
>>> 

Use LayoutParams. If you are using a LinearLayout you have to import android.widget.LinearLayout.LayoutParams, else import the proper version of LayoutParams for the layout you're using, or it will cause a ClassCastException, then:

LayoutParams layoutParams = new LayoutParams(int width, int height);
layoutParams.setMargins(int left, int top, int right, int bottom);
imageView.setLayoutParams(layoutParams);

NB: Note that you can use also imageView.setLeft(int dim), BUT THIS WON'T set the position of the component, it will set only the position of the left border of the component, the rest will remain at the same position.

In .Net 1.1 and earlier, Application.Exit was not a wise choice and the MSDN docs specifically recommended against it because all message processing stopped immediately.

In later versions however, calling Application.Exit will result in Form.Close being called on all open forms in the application, thus giving you a chance to clean up after yourself, or even cancel the operation all together.

You have specified the ajax call response dataType as:

'json'

where as the actual ajax response is not a valid JSON and as a result the JSON parser is throwing an error.

The best approach that I would recommend is to change the dataType to:

'text'

and within the success callback validate whether a valid JSON is being returned or not, and if JSON validation fails, alert it on the screen so that its obvious for what purpose the ajax call is actually failing. Have a look at this:

$.ajax({
    url: '/Admin/Ajax/GetViewContentNames',
    type: 'POST',
    dataType: 'text',
    data: {viewID: $("#view").val()},
    success: function (data) {
        try {
            var output = JSON.parse(data);
            alert(output);
        } catch (e) {
            alert("Output is not valid JSON: " + data);
        }
    }, error: function (request, error) {
        alert("AJAX Call Error: " + error);
    }
});

For those who have updated to the latest version of google-play-services_lib and/or have this error Google Play services out of date. Requires 3136100 but found 2012110 this newer version of com.google.android.gms.apk (Google Play Services 3.1.36) and com.android.vending.apk (Google Play Store 4.1.6) should work.

Test with this configuration on Android SDK Tools 22.0.1. Another configuration that targets pure Android, not the Google one, should work too.

• Device: Galaxy Nexus
• Target: Android 4.2.2 - API Level 17
• CPU/ABI: ARM (armeabi-v7a)
• Checked: Use Host GPU

...

1. Open the AVD

2. Execute this in the terminal / cmd

   adb -e install com.google.android.gms.apk
   adb -e install com.android.vending.apk
   

3. Restart the AVD

4. Have fun coding!!!

I found this way to be the easiest, cleanest and it works with the newest version of the software, which allow you to get all the bug fixes.

You can use the --ignore-table option. So you could do

mysqldump -u USERNAME -pPASSWORD DATABASE --ignore-table=DATABASE.table1 > database.sql

There is no whitespace after -p (this is not a typo).

To ignore multiple tables, use this option multiple times, this is documented to work since at least version 5.0.

If you want an alternative way to ignore multiple tables you can use a script like this:

#!/bin/bash
PASSWORD=XXXXXX
HOST=XXXXXX
USER=XXXXXX
DATABASE=databasename
DB_FILE=dump.sql
EXCLUDED_TABLES=(
table1
table2
table3
table4
tableN   
)
 
IGNORED_TABLES_STRING=''
for TABLE in "${EXCLUDED_TABLES[@]}"
do :
   IGNORED_TABLES_STRING+=" --ignore-table=${DATABASE}.${TABLE}"
done

echo "Dump structure"
mysqldump --host=${HOST} --user=${USER} --password=${PASSWORD} --single-transaction --no-data --routines ${DATABASE} > ${DB_FILE}

echo "Dump content"
mysqldump --host=${HOST} --user=${USER} --password=${PASSWORD} ${DATABASE} --no-create-info --skip-triggers ${IGNORED_TABLES_STRING} >> ${DB_FILE}

what @yabin ya says is a cool solution, just remind you that: if u still get the same problem,go to Settings-Version Control-GitHub and uncheck the Clone git repositories using ssh.

For what it's worth, here's the previously provided code encapsulated within a function.

openWindowWithPost("http://www.example.com/index.php", {
    p: "view.map",
    coords: encodeURIComponent(coords)
});

Function definition:

function openWindowWithPost(url, data) {
    var form = document.createElement("form");
    form.target = "_blank";
    form.method = "POST";
    form.action = url;
    form.style.display = "none";

    for (var key in data) {
        var input = document.createElement("input");
        input.type = "hidden";
        input.name = key;
        input.value = data[key];
        form.appendChild(input);
    }

    document.body.appendChild(form);
    form.submit();
    document.body.removeChild(form);
}

var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top;   
if (!isNaN(top)) {
$("#app_scroler").click(function () {   
$('html, body').animate({
            scrollTop: top
        }, 100);
    });
}

if you want to scroll a little above or below from specific div that add value to the top like this.....like I add 800

var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top + 800;

Add line:

import java.util.Scanner;

Then create an object of Scanner class:

Scanner s = new Scanner(System.in);

Now you can call any time:

int a = Integer.parseInt(s.nextLine());

This will store integer value from your keyboard.

You can use select ... into ... to create and populate a temp table and then query the temp table to return the result.

select *
into #TempTable
from YourTable

select *
from #TempTable

the simple way I found out: add a "li" tag on the right side of an "a" tag List item

<li></span><a><span id="expand1"></span></a></li>

On CSS file create this below:

#expand1 {
 padding-left: 40px;
}

I had this same issue just now in React.

I figured out that in the Router, Route. We cannot do this as it causes this issue of closing the mobile keyboard.

<Route 
 path = "some-path"
 component = {props => <MyComponent />}
 />

Make sure and use the render instead in this situation

<Route 
 path = "some-path"
 render = {props => <MyComponent />}
 />

Hope this helps someone

To run the python file on mac.

1. Open the preferences in atom ide. To open the preferences press 'command + . ' ( ? + , )

2. Click on the install in the preferences to install packages.

3. Search for package "script" and click on install

4. Now open the python file(with .py extension ) you want to run and press 'control + r ' (^ + r)

This will do the trick!

I have the same issue, but I see that port 80 listened by Nginx:

tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      9730/nginx 

But when I try to restart it, I have the error:

    service nginx restart

My issue was in the config file, I am set PID file, and seems system cant catch it properly:

user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

When I removed it, it worked.

String.prototype.replaceAll = function(character,replaceChar){
    var word = this.valueOf();

    while(word.indexOf(character) != -1)
        word = word.replace(character,replaceChar);

    return word;
}

For that you can use the Application object.

Startup path, just the folder, use Application.StartupPath()

Dim appPath As String = Application.StartupPath()

Full .exe path, including the program.exe name on the end:, use Application.ExecutablePath()

Dim exePath As String = Application.ExecutablePath()

You can create a pre-filled form URL from within the Form Editor, as described in the documentation for Drive Forms. You'll end up with a URL like this, for example:

https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=Mike+Jones&entry.787184751=1975-05-09&entry.1381372492&entry.960923899

buildUrls()

In this example, question 1, "Name", has an ID of 726721210, while question 2, "Birthday" is 787184751. Questions 3 and 4 are blank.

You could generate the pre-filled URL by adapting the one provided through the UI to be a template, like this:

function buildUrls() {
  var template = "https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=##Name##&entry.787184751=##Birthday##&entry.1381372492&entry.960923899";
  var ss = SpreadsheetApp.getActive().getSheetByName("Sheet1");  // Email, Name, Birthday
  var data = ss.getDataRange().getValues();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    var url = template.replace('##Name##',escape(data[i][1]))
                      .replace('##Birthday##',data[i][2].yyyymmdd());  // see yyyymmdd below
    Logger.log(url);  // You could do something more useful here.
  }
};

This is effective enough - you could email the pre-filled URL to each person, and they'd have some questions already filled in.

betterBuildUrls()

Instead of creating our template using brute force, we can piece it together programmatically. This will have the advantage that we can re-use the code without needing to remember to change the template.

Each question in a form is an item. For this example, let's assume the form has only 4 questions, as you've described them. Item [0] is "Name", [1] is "Birthday", and so on.

We can create a form response, which we won't submit - instead, we'll partially complete the form, only to get the pre-filled form URL. Since the Forms API understands the data types of each item, we can avoid manipulating the string format of dates and other types, which simplifies our code somewhat.

(EDIT: There's a more general version of this in How to prefill Google form checkboxes?)

/**
 * Use Form API to generate pre-filled form URLs
 */
function betterBuildUrls() {
  var ss = SpreadsheetApp.getActive();
  var sheet = ss.getSheetByName("Sheet1");
  var data = ss.getDataRange().getValues();  // Data for pre-fill

  var formUrl = ss.getFormUrl();             // Use form attached to sheet
  var form = FormApp.openByUrl(formUrl);
  var items = form.getItems();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    // Create a form response object, and prefill it
    var formResponse = form.createResponse();

    // Prefill Name
    var formItem = items[0].asTextItem();
    var response = formItem.createResponse(data[i][1]);
    formResponse.withItemResponse(response);

    // Prefill Birthday
    formItem = items[1].asDateItem();
    response = formItem.createResponse(data[i][2]);
    formResponse.withItemResponse(response);

    // Get prefilled form URL
    var url = formResponse.toPrefilledUrl();
    Logger.log(url);  // You could do something more useful here.
  }
};

yymmdd Function

Any date item in the pre-filled form URL is expected to be in this format: yyyy-mm-dd. This helper function extends the Date object with a new method to handle the conversion.

When reading dates from a spreadsheet, you'll end up with a javascript Date object, as long as the format of the data is recognizable as a date. (Your example is not recognizable, so instead of May 9th 1975 you could use 5/9/1975.)

// From http://blog.justin.kelly.org.au/simple-javascript-function-to-format-the-date-as-yyyy-mm-dd/
Date.prototype.yyyymmdd = function() {
  var yyyy = this.getFullYear().toString();                                    
  var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based         
  var dd  = this.getDate().toString();             

  return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]);
};

You can't send application/json directly -- it has to be a parameter of a GET/POST request.

So something like

$.post(url, {json: "...json..."}, function());

I normally use action="", which is XHTML valid and retains the GET data in the URL.

All modern browsers (tested with Chrome 4, Firefox 3.5, IE8, Opera 10 and Safari 4) will always request a favicon.ico unless you've specified a shortcut icon via <link>. So if you don't explicitly specify one, it's best to always have a favicon.ico file, to avoid a 404. Yahoo! suggests you make it small and cacheable.

And you don't have to go for a PNG just for the alpha transparency either. ICO files support alpha transparency just fine (i.e. 32-bit color), though hardly any tools allow you to create them. I regularly use Dynamic Drive's FavIcon Generator to create favicon.ico files with alpha transparency. It's the only online tool I know of that can do it.

There's also a free Photoshop plug-in that can create them.

It is also possible to include bitmaps. I think you also can use transformations on that.

<Directory /your/directorypath/>

Another solution, you can do it using ResourceLoader like this:

import org.springframework.core.io.Resource;
import org.apache.commons.io.FileUtils;

@Autowire
private ResourceLoader resourceLoader;

...

Resource resource = resourceLoader.getResource("classpath:/path/to/you/dir");
File file = resource.getFile();
Iterator<File> fi = FileUtils.iterateFiles(file, null, true);
while(fi.hasNext()) {
    load(fi.next())
}

Comments suggest that git reset --merge is an alias for git merge --abort. It is worth noticing that git merge --abort is only equivalent to git reset --merge given that a MERGE_HEAD is present. This can be read in the git help for merge command.

git merge --abort is equivalent to git reset --merge when MERGE_HEAD is present.

After a failed merge, when there is no MERGE_HEAD, the failed merge can be undone with git reset --merge, but not necessarily with git merge --abort. They are not only old and new syntax for the same thing.

Personally, I find git reset --merge much more powerful for scenarios similar to the described one, and failed merges in general.

String str = "1234.56";
float num = 0.0f;

int digits = str.length()- str.indexOf('.') - 1;

float factor = 1f;

for(int i=0;i<digits;i++) factor /= 10;

for(int i=str.length()-1;i>=0;i--){

    if(str.charAt(i) == '.'){
        factor = 1;
        System.out.println("Reset, value="+num);
        continue;
    }

    num += (str.charAt(i) - '0') * factor;
    factor *= 10;
}

System.out.println(num);

Since PyYAML's yaml.load() function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:

import yaml
with open('tree.yaml', 'r') as f:
    doc = yaml.load(f)

To access branch1 text you would use:

txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"

because, in your YAML document, the value of the branch1 key is under the treeroot key.

Usually, what I do is put the normal audio tag, and then put autoplay="true" and I don't add: controls ="true" and that usually works for me

I put this in a snippet and also made a jsfiddel here

The best code is no code, and with stored procedures you have to write at least some code in the database and code in the application to call it , whereas with LINQ to SQL or LINQ to Entities, you don't have to write any additional code beyond any other LINQ query aside from instantiating a context object.

I had this problem (403 error for each package) and I found nothing great in the internet to solve it. My .npmrc file inside my user folder was wrong and misunderstood. I changed this npmrc line from

to :

proxy = XX.XX.XXX.XXX:XXXX

The BASE acronym was defined by Eric Brewer, who is also known for formulating the CAP theorem.

The CAP theorem states that a distributed computer system cannot guarantee all of the following three properties at the same time:

• Consistency
• Availability
• Partition tolerance

A BASE system gives up on consistency.

• Basically available indicates that the system does guarantee availability, in terms of the CAP theorem.
• Soft state indicates that the state of the system may change over time, even without input. This is because of the eventual consistency model.
• Eventual consistency indicates that the system will become consistent over time, given that the system doesn't receive input during that time.

Brewer does admit that the acronym is contrived:

I came up with [the BASE] acronym with my students in their office earlier that year. I agree it is contrived a bit, but so is "ACID" -- much more than people realize, so we figured it was good enough.

I doubt there is anyway to force a browser to do anything. It would depend on the system configuration, the font used, browser settings, etc. It sounds like BS to me too.

As a note, always use relative sizes not PX.

Your line:

img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.

Try

cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

Looks like your IndexPartial action method has an argument which is a complex object. If you are passing a a lot of data (complex object), It might be a good idea to convert your action method to a HttpPost action method and use jQuery post to post data to that. GET has limitation on the query string value.

[HttpPost]
public PartialViewResult IndexPartial(DashboardViewModel m)
{
   //May be you want to pass the posted model to the parial view?
   return PartialView("_IndexPartial");
}

Your script should be

var url = "@Url.Action("IndexPartial","YourControllerName")";

var model = { Name :"Shyju", Location:"Detroit"};

$.post(url, model, function(res){
   //res contains the markup returned by the partial view
   //You probably want to set that to some Div.
   $("#SomeDivToShowTheResult").html(res);
});

Assuming Name and Location are properties of your DashboardViewModel class and SomeDivToShowTheResult is the id of a div in your page where you want to load the content coming from the partialview.

Sending complex objects?

You can build more complex object in js if you want. Model binding will work as long as your structure matches with the viewmodel class

var model = { Name :"Shyju", 
              Location:"Detroit", 
              Interests : ["Code","Coffee","Stackoverflow"]
            };

$.ajax({
    type: "POST",
    data: JSON.stringify(model),
    url: url,
    contentType: "application/json"
}).done(function (res) {
    $("#SomeDivToShowTheResult").html(res);
});

For the above js model to be transformed to your method parameter, Your View Model should be like this.

public class DashboardViewModel
{
  public string Name {set;get;}
  public string Location {set;get;}
  public List<string> Interests {set;get;}
}

And in your action method, specify [FromBody]

[HttpPost]
public PartialViewResult IndexPartial([FromBody] DashboardViewModel m)
{
    return PartialView("_IndexPartial",m);
}

A brute force approach:

• update the .gitmodules file in the supermodule to point to the new submodule url,
• add and commit the changes to supermodule/.gitmodules,
• make a new clone of the supermodule somewhere else on your computer (making sure that the latest changes to the .gitmodules file are reflected in the clone),
• change your working directory to the new clone of the supermodule,
• run git submodule update --init path-to-submodule on the submodule,

et voilà! The submodule in the new clone of the supermodule is properly configured!

Less code is better code.

Swift:

Thread.sleep(forTimeInterval: 0.06)

Have you tried to remove the proxy username and password? A similar poster encountered that issue:

Could not calculate build plan: Plugin org.apache.maven.plugins:maven-jar-plugin:2.3.2 or one of its dependencies could not be resolved

Failing that I found the following worked:

1. Delete project in Eclipse (but do not delete the contents on disk)
2. Delete all files in your Maven repository
3. Re-download all Maven dependencies:

mvn dependency:resolve

4. Start up Eclipse
5. Ensure that Eclipse is configured to use your external Maven installation (Window->Preferences->Maven->Installations)
6. Re-import the existing project(s) into Eclipse
7. Ensure that there are no Maven Eclipse plugin errors on the final screen of the project import
