In my case by removing portion "port=3306;" from the connection string solved the problem.

string strConn = "Data Source=SEZSW08;Initial Catalog=Nidhi;Integrated Security=True";
SqlConnection Con = new SqlConnection(strConn);
Con.Open();
string strCmd = "select companyName from companyinfo where CompanyName='" + cmbCompName.SelectedValue + "';";
SqlDataAdapter da = new SqlDataAdapter(strCmd, Con);
DataSet ds = new DataSet();
Con.Close();
da.Fill(ds);
cmbCompName.DataSource = ds;
cmbCompName.DisplayMember = "CompanyName";
cmbCompName.ValueMember = "CompanyName";
//cmbCompName.DataBind();
cmbCompName.Enabled = true;

Neither of these options is correct. You're trying to implement a synchronous interface asynchronously. Don't do that. The problem is that when DoOperation() returns, the operation won't be complete yet. Worse, if an exception happens during the operation (which is very common with IO operations), the user won't have a chance to deal with that exception.

What you need to do is to modify the interface, so that it is asynchronous:

interface IIO
{
    Task DoOperationAsync(); // note: no async here
}

class IOImplementation : IIO
{
    public async Task DoOperationAsync()
    {
        // perform the operation here
    }
}

This way, the user will see that the operation is async and they will be able to await it. This also pretty much forces the users of your code to switch to async, but that's unavoidable.

Also, I assume using StartNew() in your implementation is just an example, you shouldn't need that to implement asynchronous IO. (And new Task() is even worse, that won't even work, because you don't Start() the Task.)

Well, this is a very simple way to validate a number different to 0.

if (+inputNum)

It will be NaN if inputNum is not a number or false if it is 0

try kill -9 {processID}

To find the process ID you can use ps -ef | grep gedit

This can be as simple as adding ToList() in your repository. For example:

public IEnumerable<MyObject> GetMyObjectsForId(string id)
{
    using (var ctxt = new RcContext())
    {
        // causes an error
        return ctxt.MyObjects.Where(x => x.MyObjects.Id == id);
    }
}

Will yield the Db Context disposed error in the calling class but this can be resolved by explicitly exercising the enumeration by adding ToList() on the LINQ operation:

public IEnumerable<MyObject> GetMyObjectsForId(string id)
{
    using (var ctxt = new RcContext())
    {
        return ctxt.MyObjects.Where(x => x.MyObjects.Id == id).ToList();
    }
}

To disable certain items:

MenuItem item = menu.findItem(R.id.ID_ASSING_TO_THE_ITEM_IN_MENU_XML);
item.setEnabled(false);

 <c:forEach items="${sessionScope.empL}" var="emp">
            <tr>
                <td>Employee ID: <c:out value="${emp.eid}"/></td>
                <td>Employee Pass: <c:out value="${emp.ename}"/></td>  
            </tr>
        </c:forEach>

MySQL, SQL Server, PostgreSQL, SQLite support using the percent sign as the modulus:

WHERE column % 2 = 1

For Oracle, you have to use the MOD function:

WHERE MOD(column, 2) = 1

It will work on Linux kernel 2.6.28 (confirmed on 4.9.x). It won't work on FreeBSD and other Unix flavors.

Your /usr/local/bin/groovy is a shell script wrapping the Java runtime running Groovy.

Not surprisingly, this error can arise when another process is listening on the desired port. This happened today when I started an instance of the Apache Web server, listening on its default port (80), having forgotten that I already had IIS 7 running, and listening on that port. This is well explained in Port 80 is being used by SYSTEM (PID 4), what is that? Better yet, that article points to Stop http.sys from listening on port 80 in Windows, which explains a very simple way to resolve it, with just a tad of help from an elevated command prompt and a one-line edit of my hosts file.

git fsck --unreachable | grep commit should show the sha1, although the list it returns might be quite large. git show <sha1> will show if it is the commit you want.

git cherry-pick -m 1 <sha1> will merge the commit onto the current branch.

You have more static resources that the cache has room for. You can do one of the following:

• Increase the size of the cache
• Decrease the TTL for the cache
• Disable caching

For more details see the documentation for these configuration options.

For fixing such an issue I have used below code

a.divide(b, 2, RoundingMode.HALF_EVEN)

2 is precision. Now problem was resolved.

I'd like to show my jsonAnalyze method here, it does a pretty print of the JSON structure only, but in some cases can be more usefull that printing the whole JSON.

Say you have a complex JSON like this:

let theJson = {
'username': 'elen',
'email': '[email protected]',
'state': 'married',
'profiles': [
    {'name': 'elenLove', 'job': 'actor' },
    {'name': 'elenDoe', 'job': 'spy'}
],
'hobbies': ['run', 'movies'],
'status': {
    'home': { 
        'ownsHome': true,
        'addresses': [
            {'town': 'Mexico', 'address': '123 mexicoStr'},
            {'town': 'Atlanta', 'address': '4B atlanta 45-48'},
        ]
    },
    'car': {
        'ownsCar': true,
        'cars': [
            {'brand': 'Nissan', 'plate': 'TOKY-114', 'prevOwnersIDs': ['4532354531', '3454655344', '5566753422']},
            {'brand': 'Benz', 'plate': 'ELEN-1225', 'prevOwnersIDs': ['4531124531', '97864655344', '887666753422']}
        ]
    }
},
'active': true,
'employed': false,
};

Then the method will return the structure like this:

username
email
state
profiles[]
    profiles[].name
    profiles[].job
hobbies[]
status{}
    status{}.home{}
        status{}.home{}.ownsHome
        status{}.home{}.addresses[]
            status{}.home{}.addresses[].town
            status{}.home{}.addresses[].address
    status{}.car{}
        status{}.car{}.ownsCar
        status{}.car{}.cars[]
            status{}.car{}.cars[].brand
            status{}.car{}.cars[].plate
            status{}.car{}.cars[].prevOwnersIDs[]
active
employed

So this is the jsonAnalyze() code:

function jsonAnalyze(obj) {
        let arr = [];
        analyzeJson(obj, null, arr);
        return logBeautifiedDotNotation(arr);

    function analyzeJson(obj, parentStr, outArr) {
        let opt;
        if (!outArr) {
            return "no output array given"
        }
        for (let prop in obj) {
            opt = parentStr ? parentStr + '.' + prop : prop;
            if (Array.isArray(obj[prop]) && obj[prop] !== null) {
                    let arr = obj[prop];
                if ((Array.isArray(arr[0]) || typeof arr[0] == "object") && arr[0] != null) {                        
                    outArr.push(opt + '[]');
                    analyzeJson(arr[0], opt + '[]', outArr);
                } else {
                    outArr.push(opt + '[]');
                }
            } else if (typeof obj[prop] == "object" && obj[prop] !== null) {
                    outArr.push(opt + '{}');
                    analyzeJson(obj[prop], opt + '{}', outArr);
            } else {
                if (obj.hasOwnProperty(prop) && typeof obj[prop] != 'function') {
                    outArr.push(opt);
                }
            }
        }
    }

    function logBeautifiedDotNotation(arr) {
        retStr = '';
        arr.map(function (item) {
            let dotsAmount = item.split(".").length - 1;
            let dotsString = Array(dotsAmount + 1).join('    ');
            retStr += dotsString + item + '\n';
            console.log(dotsString + item)
        });
        return retStr;
    }
}

jsonAnalyze(theJson);

A space may only be encoded to "+" in the "application/x-www-form-urlencoded" content-type key-value pairs query part of an URL. In my opinion, this is a MAY, not a MUST. In the rest of URLs, it is encoded as %20.

In my opinion, it's better to always encode spaces as %20, not as "+", even in the query part of an URL, because it is the HTML specification (RFC-1866) that specified that space characters should be encoded as "+" in "application/x-www-form-urlencoded" content-type key-value pairs (see paragraph 8.2.1. subparagraph 1.)

This way of encoding form data is also given in later HTML specifications. For example, look for relevant paragraphs about application/x-www-form-urlencoded in HTML 4.01 Specification, and so on.

Here is a sample string in URL where the HTML specification allows encoding spaces as pluses: "http://example.com/over/there?name=foo+bar". So, only after "?", spaces can be replaced by pluses. In other cases, spaces should be encoded to %20. But since it's hard to correctly determine the context, it's the best practice to never encode spaces as "+".

I would recommend to percent-encode all character except "unreserved" defined in RFC-3986, p.2.3

unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

The implementation depends on the programming language that you chose.

If your URL contains national characters, first encode them to UTF-8 and then percent-encode the result.

Your CSS must be like this:

@media print {
   body {
      -webkit-print-color-adjust: exact;
   }
}

.vendorListHeading th {
   background-color: #1a4567 !important;
   color: white !important;   
}

moment.js is great but sometimes you don't want to pull a large number of dependencies for simple things.

The following works as well:

var tzoffset = (new Date()).getTimezoneOffset() * 60000; //offset in milliseconds
var localISOTime = (new Date(Date.now() - tzoffset)).toISOString().slice(0, -1);
// => '2015-01-26T06:40:36.181'

The slice(0, -1) gets rid of the trailing Z which represents Zulu timezone and can be replaced by your own.

If you have loads of re-directs to create, having loads of virtual directories over the places is a nightmare to maintain. You could try using ISAPI redirect an IIS extension. Then all you re-directs are managed in one place.

http://www.isapirewrite.com/docs/

It allows also you to match patterns based on reg ex expressions etc. I've used where I've had to re-direct 100's of pages and its saved a lot of time.

This does not want to be a "just-use-a-library" answer but just in case you're using Lodash you can use .clamp:

_.clamp(yourInput, lowerBound, upperBound);

So that:

_.clamp(22, -10, 10); // => 10

Here is its implementation, taken from Lodash source:

/**
 * The base implementation of `_.clamp` which doesn't coerce arguments.
 *
 * @private
 * @param {number} number The number to clamp.
 * @param {number} [lower] The lower bound.
 * @param {number} upper The upper bound.
 * @returns {number} Returns the clamped number.
 */
function baseClamp(number, lower, upper) {
  if (number === number) {
    if (upper !== undefined) {
      number = number <= upper ? number : upper;
    }
    if (lower !== undefined) {
      number = number >= lower ? number : lower;
    }
  }
  return number;
}

Also, it's worth noting that Lodash makes single methods available as standalone modules, so in case you need only this method, you can install it without the rest of the library:

npm i --save lodash.clamp

I found this problem when I changed my SVN password.

How to resolve First, remove Subversion folder in {Documents and Settings}{user login}\Application Data\Subversion -> It doesn't work

After, rename my current user login profile from {Documents and Settings}{user login} to {Documents and Settings}{user login}_bakup and login agian -> It work...

I assumed -> SVN or JavaHL bind authorized user with {user login} or keep it in user profile of window.

HTML

<input type="button">

CSS

input[type=button]{
 background:transparent;
 border:0;
}

You can set the border color in IE however there are some issues.

Argh... I could have sworn you could do this... just tested and realized I wasn't correct. The notes below still apply though.

1. in IE8 (Beta1 -> RC1) changing the border color or the background color/image causes a de-theming of the control in WindowsXP (the drop arrow and box look like Windows 95)

2. you still can't style the options within the select control very well because IE doesn't support it. (see bug #291)

Try to open Services Window, by writing services.msc into Start->Run and hit Enter.

When window appears, then find SQL Browser service, right click and choose Properties, and then in dropdown list choose Automatic, or Manual, whatever you want, and click OK. Eventually, if not started immediately, you can again press right click on this service and click Start.

Workaround:

template<class T, size_t N>
struct simple_array { // like std::array in C++0x
   T arr[N];
};


class C : private simple_array<int, 3> 
{
      static simple_array<int, 3> myarr() {
           simple_array<int, 3> arr = {1,2,3};
           return arr;
      }
public:
      C() : simple_array<int, 3>(myarr()) {}
};

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

For those looking for an entirely programmatic (or at least server-side) solution, I've had great success using catdoc's xls2csv tool.

Install catdoc:

apt-get install catdoc

Do the conversion:

xls2csv -d utf-8 file.xls > file-utf-8.csv 

This is blazing fast.

Note that it's important that you include the -d utf-8 flag, otherwise it will encode the output in the default cp1252 encoding, and you run the risk of losing information.

Note that xls2csv also only works with .xls files, it does not work with .xlsx files.

Description
Python string method rindex() returns the last index where the substring str is found, or raises an exception if no such index exists, optionally restricting the search to string[beg:end].

Syntax
Following is the syntax for rindex() method -

str.rindex(str, beg=0 end=len(string))

Parameters
str - This specifies the string to be searched.

beg - This is the starting index, by default its 0

len - This is ending index, by default its equal to the length of the string.

Return Value
This method returns last index if found otherwise raises an exception if str is not found.

Example
The following example shows the usage of rindex() method.

Live Demo

!/usr/bin/python

str1 = "this is string example....wow!!!";
str2 = "is";

print str1.rindex(str2)
print str1.index(str2)

When we run above program, it produces following result -

5
2

A wrapper class doesn't necessarily need to wrap another class. It might be a API class wrapping functionality in e.g. a dll file.

For example it might be very useful to create a dll wrapper class, which takes care of all dll initialization and cleanup and create class methods that wrap function pointers created from e.g. GetProcAddress().

Expanding Rentering.com's answer, in scenarios where a whole graph of many types is to be taken care of, and you're looking for a strongly typed solution, this class can help, see usage (fluent) below. It operates as either a black-list or white-list per type. A type cannot be both (Gist - also contains global ignore list).

public class PropertyFilterResolver : DefaultContractResolver
{
  const string _Err = "A type can be either in the include list or the ignore list.";
  Dictionary<Type, IEnumerable<string>> _IgnorePropertiesMap = new Dictionary<Type, IEnumerable<string>>();
  Dictionary<Type, IEnumerable<string>> _IncludePropertiesMap = new Dictionary<Type, IEnumerable<string>>();
  public PropertyFilterResolver SetIgnoredProperties<T>(params Expression<Func<T, object>>[] propertyAccessors)
  {
    if (propertyAccessors == null) return this;

    if (_IncludePropertiesMap.ContainsKey(typeof(T))) throw new ArgumentException(_Err);

    var properties = propertyAccessors.Select(GetPropertyName);
    _IgnorePropertiesMap[typeof(T)] = properties.ToArray();
    return this;
  }

  public PropertyFilterResolver SetIncludedProperties<T>(params Expression<Func<T, object>>[] propertyAccessors)
  {
    if (propertyAccessors == null)
      return this;

    if (_IgnorePropertiesMap.ContainsKey(typeof(T))) throw new ArgumentException(_Err);

    var properties = propertyAccessors.Select(GetPropertyName);
    _IncludePropertiesMap[typeof(T)] = properties.ToArray();
    return this;
  }

  protected override IList<JsonProperty> CreateProperties(Type type, MemberSerialization memberSerialization)
  {
    var properties = base.CreateProperties(type, memberSerialization);

    var isIgnoreList = _IgnorePropertiesMap.TryGetValue(type, out IEnumerable<string> map);
    if (!isIgnoreList && !_IncludePropertiesMap.TryGetValue(type, out map))
      return properties;

    Func<JsonProperty, bool> predicate = jp => map.Contains(jp.PropertyName) == !isIgnoreList;
    return properties.Where(predicate).ToArray();
  }

  string GetPropertyName<TSource, TProperty>(
  Expression<Func<TSource, TProperty>> propertyLambda)
  {
    if (!(propertyLambda.Body is MemberExpression member))
      throw new ArgumentException($"Expression '{propertyLambda}' refers to a method, not a property.");

    if (!(member.Member is PropertyInfo propInfo))
      throw new ArgumentException($"Expression '{propertyLambda}' refers to a field, not a property.");

    var type = typeof(TSource);
    if (!type.GetTypeInfo().IsAssignableFrom(propInfo.DeclaringType.GetTypeInfo()))
      throw new ArgumentException($"Expresion '{propertyLambda}' refers to a property that is not from type '{type}'.");

    return propInfo.Name;
  }
}

Usage:

var resolver = new PropertyFilterResolver()
  .SetIncludedProperties<User>(
    u => u.Id, 
    u => u.UnitId)
  .SetIgnoredProperties<Person>(
    r => r.Responders)
  .SetIncludedProperties<Blog>(
    b => b.Id)
  .Ignore(nameof(IChangeTracking.IsChanged)); //see gist

Regexes can also limit the number of characters.

r = re.compile("^[a-z]{1,15}$")

gives you a regex that only matches if the input is entirely lowercase ASCII letters and 1 to 15 characters long.

Although, I had all proper babel loaders in my .babelrc config file. This build script with parcel-bundler was producing the unexpected token error < and mime type errors in the browser console for me on manual page refresh.

"scripts": {
    "build": "parcel build ui/index.html --public-url ./",
    "dev": "parcel watch ui/index.html"
 }

Updating the build script fixed the issues for me.

"scripts": {
    "build": "parcel build ui/index.html",
    "ui": "parcel watch ui/index.html"
 }

An array is created with the -split operator. Like so,

$myString="Four score and seven years ago"
$arr = $myString -split ' '
$arr # Print output
Four
score
and
seven
years
ago

When you need a certain item, use array index to reach it. Mind that index starts from zero. Like so,

$arr[2] # 3rd element
and
$arr[4] # 5th element
years

Ones that are built using a recent webkit build, and Presto.

Safari 3.1 for webkit
Opera for Presto.

I'm pretty sure firefox will start supporting html5 partially in 3.1

All support is extremely partial. Check here for information on what is supported.

If obj Is Nothing Then
    ' need to initialize obj: '
    Set obj = ...
Else
    ' obj already set / initialized. '
End If

Or, if you prefer it the other way around:

If Not obj Is Nothing Then
    ' obj already set / initialized. '
Else
    ' need to initialize obj: '
    Set obj = ...
End If

Using

find / -name virtualenvwrapper.sh

I got a TON of "permissions denied"s, and exactly one printout of the file location. I missed it until I found that file location when I uninstall/installed it again with pip.

In case you were curious, it was in

I saw some contradictions in the answers above, I just tried the following on Oracle 12c and the following is correct :

LEFT OUTER JOIN

SELECT *
FROM A, B
WHERE A.column = B.column(+)

RIGHT OUTER JOIN

SELECT *
FROM A, B
WHERE B.column(+) = A.column

None of the above answers (or any of the dozens of answers I saw elsewhere) worked for me when using brew with the most recent version of mysql and yosemite. I ended up installing a different mysql version via brew.

Specifying an older version by saying (for example)

brew install mysql56

Worked for me. Hope this helps someone. This was a frustrating problem that I felt like I was stuck on forever.

You could try using float:left; or display:inline-block;.

Both of these will change the element's behaviour from defaulting to 100% width to defaulting to the natural width of its contents.

However, note that they'll also both have an impact on the layout of the surrounding elements as well. I would suggest that inline-block will have less of an impact though, so probably best to try that first.

I used Abdurrahim's suggestion. However, it seemed to give a weird time format and also added the abbreviation for the day as part of the build date; example: Sun 12/24/2017 13:21:05.43. I only needed just the date so I had to eliminate the rest using substring.

After adding the echo %date% %time% > "$(ProjectDir)\Resources\BuildDate.txt"to the pre-build event, I just did the following:

string strBuildDate = YourNamespace.Properties.Resources.BuildDate;
string strTrimBuildDate = strBuildDate.Substring(4).Remove(10);

The good news here is that it worked.

For this your android application must have uploaded into the android market. when you upload it on the android market then use the following code to open the market with your android application.

    Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id=<packagename>"));
startActivity(intent);

If you want it to download and install from your own server then use the following code

Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.example.com/sample/test.apk"));
    startActivity(intent);

In my opinion, jQuery's animate is a bit overused, compared to the CSS3 transition, which performs such animation on any 2D or 3D property. Also I'm afraid, that leaving it to the browser and by forgetting the layer called JavaScript could lead to spare CPU juice - specially, when you wish to blast with the animations. Thus, I like to have animations where the style definitions are, since you define functionality with JavaScript. The more presentation you inject into JavaScript, the more problems you'll face later on.

All you have to do is to use addClass to the element you wish to animate, where you set a class that has CSS transition properties. You just "activate" the animation, which stays implemented on the pure presentation layer.

.js

// with jQuery
$("#element").addClass("Animate");

// without jQuery library
document.getElementById("element").className += "Animate";

One could easly remove a class with jQuery, or remove a class without library.

.css

#element{
    color      : white;
}

#element.Animate{
    transition        : .4s linear;
    color             : red;
    /** 
     * Not that ugly as the JavaScript approach.
     * Easy to maintain, the most portable solution.
     */
    -webkit-transform : rotate(90deg);
}

.html

<span id="element">
    Text
</span>

This is a fast and convenient solution for most use cases.

I also use this when I want to implement a different styling (alternative CSS properties), and wish to change the style on-the-fly with a global .5s animation. I add a new class to the BODY, while having alternative CSS in a form like this:

.js

$("BODY").addClass("Alternative");

.css

BODY.Alternative #element{
    color      : blue;
    transition : .5s linear;
}

This way you can apply different styling with animations, without loading different CSS files. You only involve JavaScript to set a class.

Adding a solution which I've recently used myself and haven't seen mentioned here. If you have Apache Commons Collections available then you can use the SetUtils#difference method:

// Returns all the elements of test2 which are not in test1
SetUtils.difference(test2, test1) 

Note that according to the documentation the returned set is an unmodifiable view:

Returns a unmodifiable view containing the difference of the given Sets, denoted by a \ b (or a - b). The returned view contains all elements of a that are not a member of b.

Full documentation: https://commons.apache.org/proper/commons-collections/apidocs/org/apache/commons/collections4/SetUtils.html#difference-java.util.Set-java.util.Set-

I had the same issue and found the answer here.

The problem is that the bat uses de reg command and it searches that in the PATH system variable. Somehow you have managed to get "C:\Windows\System32" out of the PATH variable, so just go to the system variables (right click "My Computer" > "Properties" > advanced config > "Environment Variables", search the PATH variable and add at the end separated by ";" : C:\Windows\System32

Everything that is business logic belongs in a model, whether it is a database query, calculations, a REST call, etc.

You can have the data access in the model itself, the MVC pattern doesn't restrict you from doing that. You can sugar coat it with services, mappers and what not, but the actual definition of a model is a layer that handles business logic, nothing more, nothing less. It can be a class, a function, or a complete module with a gazillion objects if that's what you want.

It's always easier to have a separate object that actually executes the database queries instead of having them being executed in the model directly: this will especially come in handy when unit testing (because of the easiness of injecting a mock database dependency in your model):

class Database {
   protected $_conn;

   public function __construct($connection) {
       $this->_conn = $connection;
   }

   public function ExecuteObject($sql, $data) {
       // stuff
   }
}

abstract class Model {
   protected $_db;

   public function __construct(Database $db) {
       $this->_db = $db;
   }
}

class User extends Model {
   public function CheckUsername($username) {
       // ...
       $sql = "SELECT Username FROM" . $this->usersTableName . " WHERE ...";
       return $this->_db->ExecuteObject($sql, $data);
   }
}

$db = new Database($conn);
$model = new User($db);
$model->CheckUsername('foo');

Also, in PHP, you rarely need to catch/rethrow exceptions because the backtrace is preserved, especially in a case like your example. Just let the exception be thrown and catch it in the controller instead.

An alternative solution for preventing functions to change the user par. You can set the default parameters early on the function, so that the graphical parameters and layout will not be changed during the function execution. See ?on.exit for further details.

on.exit(layout(1))
opar<-par(no.readonly=TRUE)
on.exit(par(opar),add=TRUE,after=FALSE)

In the case where an optional, typed parameter is good enough, consider the following code which accomplishes the same without repeating the properties or defining an interface:

export class Track {
   public title: string;
   public artist: string;
   public lyrics: string;

   constructor(track?: Track) {
     Object.assign(this, track);
   }
}

Keep in mind this will assign all properties passed in track, eve if they're not defined on Track.

Not directly the requested answer, but maybe the root-cause of the question:

You can also prevent commands from even getting into the history, by prefixing them with a space character:

# This command will be in the history
echo Hello world

# This will not
 echo Hello world

Cron's granularity is in minutes and was not designed to wake up every x seconds to run something. Run your repeating task within a loop and it should do what you need:

#!/bin/env bash
while [ true ]; do
 sleep 30
 # do what you need to here
done

In order to make numpy display float arrays in an arbitrary format, you can define a custom function that takes a float value as its input and returns a formatted string:

In [1]: float_formatter = "{:.2f}".format

The f here means fixed-point format (not 'scientific'), and the .2 means two decimal places (you can read more about string formatting here).

Let's test it out with a float value:

In [2]: float_formatter(1.234567E3)
Out[2]: '1234.57'

To make numpy print all float arrays this way, you can pass the formatter= argument to np.set_printoptions:

In [3]: np.set_printoptions(formatter={'float_kind':float_formatter})

Now numpy will print all float arrays this way:

In [4]: np.random.randn(5) * 10
Out[4]: array([5.25, 3.91, 0.04, -1.53, 6.68]

Note that this only affects numpy arrays, not scalars:

In [5]: np.pi
Out[5]: 3.141592653589793

It also won't affect non-floats, complex floats etc - you will need to define separate formatters for other scalar types.

You should also be aware that this only affects how numpy displays float values - the actual values that will be used in computations will retain their original precision.

For example:

In [6]: a = np.array([1E-9])

In [7]: a
Out[7]: array([0.00])

In [8]: a == 0
Out[8]: array([False], dtype=bool)

numpy prints a as if it were equal to 0, but it is not - it still equals 1E-9.

If you actually want to round the values in your array in a way that affects how they will be used in calculations, you should use np.round, as others have already pointed out.

Use compareTo:

date1.compareTo(date2);

For anyone having this problem with newer versions of Eclipse, head over to Window->Preferences->Java->Editor->Content assist->Advanced and mark Java Proposals and Chain Template Proposals as active.

Filenames with "jpg" and "png" extensions in "path/to/images":

import os
accepted_extensions = ["jpg", "png"]
filenames = [fn for fn in os.listdir("path/to/images") if fn.split(".")[-1] in accepted_extensions]

upload_max_filesize = 8M;
post_max_size = 8M;

Imagine you already changed above values. But what happen when user try to upload large files greater than 8M ?

This is what happen, PHP shows this warning!

Warning: POST Content-Length of x bytes exceeds the limit of y bytes in Unknown on line 0

you can avoid it by adding

ob_get_contents();
ob_end_clean();

I don't think you want the data from your Request, I think you want the data from your Response. The two are different. Also you should build your response correctly in your controller.

Looking at the class in edit #2, I would make it look like this:

class XmlController extends Controller
{
    public function index()
    {
        $content = Request::all();
        return Response::json($content);
    }
}

Once you've gotten that far you should check the content of your response in your test case (use print_r if necessary), you should see the data inside.

I assume you are using TCP sockets for the client-server interaction? One way to send different types of data to the server and have it be able to differentiate between the two is to dedicate the first byte (or more if you have more than 256 types of messages) as some kind of identifier. If the first byte is one, then it is message A, if its 2, then its message B. One easy way to send this over the socket is to use DataOutputStream/DataInputStream:

Client:

Socket socket = ...; // Create and connect the socket
DataOutputStream dOut = new DataOutputStream(socket.getOutputStream());

// Send first message
dOut.writeByte(1);
dOut.writeUTF("This is the first type of message.");
dOut.flush(); // Send off the data

// Send the second message
dOut.writeByte(2);
dOut.writeUTF("This is the second type of message.");
dOut.flush(); // Send off the data

// Send the third message
dOut.writeByte(3);
dOut.writeUTF("This is the third type of message (Part 1).");
dOut.writeUTF("This is the third type of message (Part 2).");
dOut.flush(); // Send off the data

// Send the exit message
dOut.writeByte(-1);
dOut.flush();

dOut.close();

Server:

Socket socket = ... // Set up receive socket
DataInputStream dIn = new DataInputStream(socket.getInputStream());

boolean done = false;
while(!done) {
  byte messageType = dIn.readByte();

  switch(messageType)
  {
  case 1: // Type A
    System.out.println("Message A: " + dIn.readUTF());
    break;
  case 2: // Type B
    System.out.println("Message B: " + dIn.readUTF());
    break;
  case 3: // Type C
    System.out.println("Message C [1]: " + dIn.readUTF());
    System.out.println("Message C [2]: " + dIn.readUTF());
    break;
  default:
    done = true;
  }
}

dIn.close();

Obviously, you can send all kinds of data, not just bytes and strings (UTF).

Note that writeUTF writes a modified UTF-8 format, preceded by a length indicator of an unsigned two byte encoded integer giving you 2^16 - 1 = 65535 bytes to send. This makes it possible for readUTF to find the end of the encoded string. If you decide on your own record structure then you should make sure that the end and type of the record is either known or detectable.

I'm assuming you are talking about the event bubbling aspect of it. It would be helpful to see your HTML for the said span elements as well. I can't see why you'd want to change the core behavior like this, I don't find it at all annoying. I suggest going with your second block of code:

$('span').click(function (){
  doStuff2();
  doStuff1();
});

Most importantly I think you'll find it more organized if you manage all the events for a given element in the same block like you've illustrated. Can you explain why you find this annoying?

As of R 3.3.0, one may use startsWith() as a faster alternative to grepl():

which(startsWith(mydata_2$height_seca1, 1578))

I've finally worked it out. The biggest issue is how they managed to work out what Wireless networks were around me and how do they know where these networks are.

It "seems" to be something similar to this:

1. skyhookwireless.com [or similar] Company has mapped the location of many wireless access points, i assume by similar means that google streetview went around and picked up all the photos.
2. Using Google gears and my browser, we can report which wireless networks i see and have around me
3. Compare these wireless points to their geolocation and triangulate my position.

May I recommend dom-to-image library, that was written solely to address this problem (I'm the maintainer).
Here is how you use it (some more here):

var node = document.getElementById('my-node');

domtoimage.toPng(node)
    .then (function (dataUrl) {
        var img = new Image();
        img.src = dataUrl;
        document.appendChild(img);
    })
    .catch(function (error) {
        console.error('oops, something went wrong!', error);
    });

Change your table declaration to:

I spent over 3 hours to find out solution. Actually port 80 was being used by "system" service so I tried to change port from 80 to 8080 in "httpd" file but same problem raised "port 80 is used by system". It had driven me mad for 3 hours as every thing was changed like port , localhost server etc pointing to 8080.

At last I found mistake that was server root. Basically "Server Root" in "httpd" should be pointing to apache foler of xampp. In my case that's was

ServerRoot "xampp/apache"

I just changed it as follows:

ServerRoot "C:/xampp/apache" 

It has worked successfully and now everything is running with OK status.

If you add the boolean true to the reload window.location.reload(true) it will load from server.

It is not clear how supported this boolean is, W3Org mentions that NS used to support it

There MIGHT be a difference between the content of window.location.href and document.URL - there at least used to be a difference between location.href and the non-standard and deprecated document.location that had to do with redirection, but that is really last millennium.

For documentation purposes I would use window.location.reload() because that is what you want to do.

To reduce the risk you can also associate the originating IP with the session. That way an attacker has to be within the same private network to be able to use the session.

Checking referer headers can also be an option but those are more easily spoofed.

System.out.println("...") in Java code is translated into JVM. Looking into the JVM gave me better understanding what is going on behind the hood.

From the book Programming form the Java Virtual Machine. This code is copied from https://github.com/ymasory/programming-for-the-jvm/blob/master/examples/HelloWorld.j.

This is the JVM source code.

.class public HelloWorld
.super java/lang/Object

.method public static main([Ljava/lang/String;)V
.limit stack 2
.limit locals 1
  getstatic java/lang/System/out Ljava/io/PrintStream;
  ldc "Hello, world"
  invokevirtual java/io/PrintStream/println
    (Ljava/lang/String;)V
  return

.end method
.end class

As "The JVM doesn't permit byte-level access to memory" the out object in type Ljava/io/PrintSteram; is stored in a stack with getstatic JVM command. Then the argument is pushed on the stack before called a method println of the java/io/PrintStream class from an instance named out. The method's parameter is (Ljava/lang/String;) and output type is void (V).

you can use COUNT(DISTINCT ip), this will only count distinct values

What comes after the "Where" is a constraint on the generic type T you declared, so:

• class means that the T should be a class and not a value type or a struct.

• new() indicates that the T class should have a public parameter-free default constructor defined.

If you just have the currency symbol and the number of decimal places, you can use the following helper function, which respects the symbol/amount order, separators etc, only changing the currency symbol itself and the number of decimal places to display to.

public static string FormatCurrency(string currencySymbol, Decimal currency, int decPlaces)
{
    NumberFormatInfo localFormat = (NumberFormatInfo)NumberFormatInfo.CurrentInfo.Clone();
    localFormat.CurrencySymbol = currencySymbol;
    localFormat.CurrencyDecimalDigits = decPlaces;
    return currency.ToString("c", localFormat);
}

 //To send from the activity that is calling another activity via myIntent

    myIntent.putExtra("id","10");
    startActivity(myIntent);

    //To receive from another Activity

            Bundle bundle = getIntent().getExtras();
            String id=bundle.getString("id");

If the list you use for the spinner is an object then you can find its position like this

private int selectSpinnerValue( List<Object> ListSpinner,String myString) 
{
    int index = 0;
    for(int i = 0; i < ListSpinner.size(); i++){
      if(ListSpinner.get(i).getValueEquals().equals(myString)){
          index=i;
          break;
      }
    }
    return index;
}

using:

 int index=selectSpinnerValue(ListOfSpinner,StringEquals);
    spinner.setSelection(index,true);

Here's what I had to do to setup basic auth on Ubuntu 14.04 (didn't find a guide anywhere else)

Basic squid conf

/etc/squid3/squid.conf instead of the super bloated default config file

auth_param basic program /usr/lib/squid3/basic_ncsa_auth /etc/squid3/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

# Choose the port you want. Below we set it to default 3128.
http_port 3128

Please note the basic_ncsa_auth program instead of the old ncsa_auth

squid 2.x

For squid 2.x you need to edit /etc/squid/squid.conf file and place:

auth_param basic program /usr/lib/squid/digest_pw_auth /etc/squid/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

Setting up a user

sudo htpasswd -c /etc/squid3/passwords username_you_like

and enter a password twice for the chosen username then

sudo service squid3 restart

squid 2.x

sudo htpasswd -c /etc/squid/passwords username_you_like

and enter a password twice for the chosen username then

sudo service squid restart

htdigest vs htpasswd

For the many people that asked me: the 2 tools produce different file formats:

• htdigest stores the password in plain text.
• htpasswd stores the password hashed (various hashing algos are available)

Despite this difference in format basic_ncsa_auth will still be able to parse a password file generated with htdigest. Hence you can alternatively use:

sudo htdigest -c /etc/squid3/passwords realm_you_like username_you_like

Beware that this approach is empirical, undocumented and may not be supported by future versions of Squid.

On Ubuntu 14.04 htdigest and htpasswd are both available in the [apache2-utils][1] package.

MacOS

Similar as above applies, but file paths are different.

Install squid

brew install squid

Start squid service

brew services start squid

Squid config file is stored at /usr/local/etc/squid.conf.

Comment or remove following line:

http_access allow localnet

Then similar to linux config (but with updated paths) add this:

auth_param basic program /usr/local/Cellar/squid/4.8/libexec/basic_ncsa_auth /usr/local/etc/squid_passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

Note that path to basic_ncsa_auth may be different since it depends on installed version when using brew, you can verify this with ls /usr/local/Cellar/squid/. Also note that you should add the above just bellow the following section:

#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

Now generate yourself a user:password basic auth credential (note: htpasswd and htdigest are also both available on MacOS)

htpasswd -c /usr/local/etc/squid_passwords username_you_like

Restart the squid service

brew services restart squid

This isn't easy, unless your regexp engine has special support for it. The easiest way would be to use a negative-match option, for example:

$var !~ /^foo$/
    or die "too much foo";

If not, you have to do something evil:

$var =~ /^(($)|([^f].*)|(f[^o].*)|(fo[^o].*)|(foo.+))$/
    or die "too much foo";

That one basically says "if it starts with non-f, the rest can be anything; if it starts with f, non-o, the rest can be anything; otherwise, if it starts fo, the next character had better not be another o".

You can also take advantage of the fact that a lambda or anonymous method can close over variables in its enclosing scope.

MyType result;

SimpleUsing.DoUsing(db => 
{
  result = db.SomeQuery(); //whatever returns the MyType result
}); 

//do something with result

var origParseFloat = parseFloat;
parseFloat = function(str) {
     alert("And I'm in your floats!");
     return origParseFloat(str);
}

pushing commits, whether empty or not, causes eventual git hooks to be triggered. This can do either nothing or have world shattering consequences.

So that's how you request a phone number through the Play Services API without the permission and hacks. Source and Full example.

In your build.gradle (version 10.2.x and higher required):

compile "com.google.android.gms:play-services-auth:$gms_version"

In your activity (the code is simplified):

@Override
protected void onCreate(Bundle savedInstanceState) {
    // ...
    googleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Auth.CREDENTIALS_API)
            .build();
    requestPhoneNumber(result -> {
        phoneET.setText(result);
    });
}

public void requestPhoneNumber(SimpleCallback<String> callback) {
    phoneNumberCallback = callback;
    HintRequest hintRequest = new HintRequest.Builder()
            .setPhoneNumberIdentifierSupported(true)
            .build();

    PendingIntent intent = Auth.CredentialsApi.getHintPickerIntent(googleApiClient, hintRequest);
    try {
        startIntentSenderForResult(intent.getIntentSender(), PHONE_NUMBER_RC, null, 0, 0, 0);
    } catch (IntentSender.SendIntentException e) {
        Logs.e(TAG, "Could not start hint picker Intent", e);
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == PHONE_NUMBER_RC) {
        if (resultCode == RESULT_OK) {
            Credential cred = data.getParcelableExtra(Credential.EXTRA_KEY);
            if (phoneNumberCallback != null){
                phoneNumberCallback.onSuccess(cred.getId());
            }
        }
        phoneNumberCallback = null;
    }
}

This will generate a dialog like this:

For the last enterprise application I worked on that needed to handle a notable amount of CSV -- a couple of months ago -- I used SuperCSV at sourceforge and found it simple, robust and problem-free.

I haven't done SWING development since my early CS classes but if it wasn't built in you could just inherit javax.swing.AbstractButton and create your own. Should be pretty simple to wire something together with their existing framework.

You could try and add an @Controller annotation on top of your myController Class and try the following url /<webappname>/my/hello.html. This is because org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping prepends /my to each RequestMapping in the myController class.

You can obtain all jQuery events using $._data($('[selector]')[0],'events'); change [selector] to what you need.

There is a plugin that gather all events attached by jQuery called eventsReport.

Also i write my own plugin that do this with better formatting.

But anyway it seems we can't gather events added by addEventListener method. May be we can wrap addEventListener call to store events added after our wrap call.

It seems the best way to see events added to an element with dev tools.

But you will not see delegated events there. So there we need jQuery eventsReport.

UPDATE: NOW We CAN see events added by addEventListener method SEE RIGHT ANSWER TO THIS QUESTION.

Took me some time to find the solution.

In case your server response correctly and the request is the problem, you should add withCredentials: true to the xhrFields in the request:

$.ajax({
    url: url,
    type: method,
    // This is the important part
    xhrFields: {
        withCredentials: true
    },
    // This is the important part
    data: data,
    success: function (response) {
        // handle the response
    },
    error: function (xhr, status) {
        // handle errors
    }
});

Note: jQuery >= 1.5.1 is required

A server socket listens on a single port. All established client connections on that server are associated with that same listening port on the server side of the connection. An established connection is uniquely identified by the combination of client-side and server-side IP/Port pairs. Multiple connections on the same server can share the same server-side IP/Port pair as long as they are associated with different client-side IP/Port pairs, and the server would be able to handle as many clients as available system resources allow it to.

On the client-side, it is common practice for new outbound connections to use a random client-side port, in which case it is possible to run out of available ports if you make a lot of connections in a short amount of time.

I tried to improve the suggestion from mshutov. I added the option to use the output as an object.

 function Test-Port($hostname, $port)
    {
    # This works no matter in which form we get $host - hostname or ip address
    try {
        $ip = [System.Net.Dns]::GetHostAddresses($hostname) | 
            select-object IPAddressToString -expandproperty  IPAddressToString
        if($ip.GetType().Name -eq "Object[]")
        {
            #If we have several ip's for that address, let's take first one
            $ip = $ip[0]
        }
    } catch {
        Write-Host "Possibly $hostname is wrong hostname or IP"
        return
    }
    $t = New-Object Net.Sockets.TcpClient
    # We use Try\Catch to remove exception info from console if we can't connect
    try
    {
        $t.Connect($ip,$port)
    } catch {}

    if($t.Connected)
    {
        $t.Close()
        $object = [pscustomobject] @{
                        Hostname = $hostname
                        IP = $IP
                        TCPPort = $port
                        GetResponse = $True }
        Write-Output $object
    }
    else
    {
        $object = [pscustomobject] @{
                        Computername = $IP
                        TCPPort = $port
                        GetResponse = $False }
        Write-Output $object

    }
    Write-Host $msg
}

$filterQuery = $this->queryFactory->create(QueryInterface::TYPE_BOOL, ['must' => $queries,'should'=>$queriesGeo]);

In must you need to add the query condition array which you want to work with AND and in should you need to add the query condition which you want to work with OR.

You can check this: https://github.com/Smile-SA/elasticsuite/issues/972

You can also use .filter()

$('.slide-link').filter('[data-slide="0"]').addClass('active');

The accepted answer is correct, but not complete. In order for Select All to be the default option, the Available Values dataset must contain at least 2 columns: value and label. They can return the same data, but their names have to be different. The Default Values dataset will then use value column and then Select All will be the default value. If the dataset returns only 1 column, only the last record's value will be selected in the drop down of the parameter.

You must place the label after a caption in order to for label to store the table's number, not the chapter's number.

\begin{table}
\begin{tabular}{| p{5cm} | p{5cm} | p{5cm} |}
  -- cut --
\end{tabular}
\caption{My table}
\label{table:kysymys}
\end{table}

Table \ref{table:kysymys} on page \pageref{table:kysymys} refers to the ...

You did everything correctly!

You might also change the email configuration, depending on if the email server is also the same server. The email configuration is in gitlab.yml for the mails sent by GitLab and also the admin-email.

You should be able to use something similar to:

$('#selectElementId').change(
    function(){
         $(this).closest('form').trigger('submit');
         /* or:
         $('#formElementId').trigger('submit');
            or:
         $('#formElementId').submit();
         */
    });

How about:

SELECT count(column_1)
FROM
    (SELECT * FROM temptable
    GROUP BY column_1, column_2, column_3, column_4) AS Records

(this answer was added to provide shorter and more generic examples to the question - without including all the case-specific details in the original question).

There are two distinct "problems" here, the first is if a table or subquery has no rows, the second is if there are NULL values in the query.

For all versions I've tested, postgres and mysql will ignore all NULL values when averaging, and it will return NULL if there is nothing to average over. This generally makes sense, as NULL is to be considered "unknown". If you want to override this you can use coalesce (as suggested by Luc M).

$ create table foo (bar int);
CREATE TABLE

$ select avg(bar) from foo;
 avg 
-----

(1 row)

$ select coalesce(avg(bar), 0) from foo;
 coalesce 
----------
        0
(1 row)

$ insert into foo values (3);
INSERT 0 1
$ insert into foo values (9);
INSERT 0 1
$ insert into foo values (NULL);
INSERT 0 1
$ select coalesce(avg(bar), 0) from foo;
      coalesce      
--------------------
 6.0000000000000000
(1 row)

of course, "from foo" can be replaced by "from (... any complicated logic here ...) as foo"

Now, should the NULL row in the table be counted as 0? Then coalesce has to be used inside the avg call.

$ select coalesce(avg(coalesce(bar, 0)), 0) from foo;
      coalesce      
--------------------
 4.0000000000000000
(1 row)

import platform
platform.architecture()

From the Python docs:

Queries the given executable (defaults to the Python interpreter binary) for various architecture information.

Returns a tuple (bits, linkage) which contain information about the bit architecture and the linkage format used for the executable. Both values are returned as strings.

I've added the following script as manage.sh inside my Django project, it sources the virtualenv and then runs the manage.py script with whatever arguments you pass to it. It makes it very easy in general to run commands inside the virtualenv (cron, systemd units, basically anywhere):

#! /bin/bash

# this is a convenience script that first sources the venv (assumed to be in
# ../venv) and then executes manage.py with whatever arguments you supply the
# script with. this is useful if you need to execute the manage.py from
# somewhere where the venv isn't sourced (e.g. system scripts)

# get the script's location
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" >/dev/null 2>&1 && pwd )"

# source venv <- UPDATE THE PATH HERE WITH YOUR VENV's PATH
source $DIR/../venv/bin/activate

# run manage.py script
$DIR/manage.py "$@"

Then in your cron entry you can just run:

0 3 * * * /home/user/project/manage.sh command arg

Just remember that you need to make the manage.sh script executable

One thing you might want to look at is the Commons DBCP project. It provides a BasicDataSource that is configured fairly similarly to your example. To use that you need the database vendor's JDBC JAR in your classpath and you have to specify the vendor's driver class name and the database URL in the proper format.

Edit:

If you want to configure a BasicDataSource for MySQL, you would do something like this:

BasicDataSource dataSource = new BasicDataSource();

dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUsername("username");
dataSource.setPassword("password");
dataSource.setUrl("jdbc:mysql://<host>:<port>/<database>");
dataSource.setMaxActive(10);
dataSource.setMaxIdle(5);
dataSource.setInitialSize(5);
dataSource.setValidationQuery("SELECT 1");

Code that needs a DataSource can then use that.

In my case, I messed up the connectionString property in a publish profile, trying to access the wrong database (Initial Catalog). Entity Framework then complains that the entities do not match the database, and rightly so.

You are correct in that your list contains a reference to the original dictionary.

a.append(b.copy()) should do the trick.

Bear in mind that this makes a shallow copy. An alternative is to use copy.deepcopy(b), which makes a deep copy.

The current answer for Swift 2.x and higher (from the Swift Programming Language guide on Collection Types) seems to be to either iterate over the Set entries like so:

for item in myItemSet {
   ...
}

Or, to use the "sorted" method:

let itemsArray = myItemSet.sorted()

It seems the Swift designers did not like allObjects as an access mechanism because Sets aren't really ordered, so they wanted to make sure you didn't get out an array without an explicit ordering applied.

If you don't want the overhead of sorting and don't care about the order, I usually use the map or flatMap methods which should be a bit quicker to extract an array:

let itemsArray = myItemSet.map { $0 }

Which will build an array of the type the Set holds, if you need it to be an array of a specific type (say, entitles from a set of managed object relations that are not declared as a typed set) you can do something like:

var itemsArray : [MyObjectType] = []
if let typedSet = myItemSet as? Set<MyObjectType> {
 itemsArray = typedSet.map { $0 }
}

For records == 0, rjmunro's solution gives 1. The correct solution is 0. That said, if you know that records > 0 (and I'm sure we've all assumed recordsPerPage > 0), then rjmunro solution gives correct results and does not have any of the overflow issues.

int pageCount = 0;
if (records > 0)
{
    pageCount = (((records - 1) / recordsPerPage) + 1);
}
// no else required

All the integer math solutions are going to be more efficient than any of the floating point solutions.

Use an call thru section, it works

<div id="content">
     <section id="home">
               ...
     </section>

Call the above the thru

 <a href="#home">page1</a>

Scrolling needs jquery paste this.. on above to ending body closing tag..

<script>
  $(function() {
      $('a[href*=#]:not([href=#])').click(function() {
          if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
              var target = $(this.hash);
              target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
              if (target.length) {
                  $('html,body').animate({
                      scrollTop: target.offset().top
                  }, 1000);
                  return false;
              }
          }
      });
  });
</script>

gethostname() is POSIX way to get local host name. Check out man.

BSD function getdomainname() can give you domain name so you can build fully qualified hostname. There is no POSIX way to get a domain I'm afraid.

int pow( int base, int exponent)

{   // Does not work for negative exponents. (But that would be leaving the range of int) 
    if (exponent == 0) return 1;  // base case;
    int temp = pow(base, exponent/2);
    if (exponent % 2 == 0)
        return temp * temp; 
    else
        return (base * temp * temp);
}

The password is 'ubuntu' for the 'ubuntu' user (at least in docker for ubuntu :14.04.03).

NB: 'ubuntu' is created after the startup of the container so, if you just do this:

 docker run -i -t --entrypoint /bin/bash  ubuntu     

You'll get the root prompt directly. From there you can force the password change of root, commit the container and optionally tag it (with -f) to ubuntu:latest like this:

root@ec384466fbbb:~# passwd
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
root@ec384466fbbb:~# exit

% docker commit ec3844
5d3c03e7d6d861ce519fe33b184cd477b8ad03247ffe19b2a57d3f0992d71bca

docker tag -f 5d3c ubuntu:latest

You must rebuild your eventual dependencies on ubuntu:latest.

Are you missing the reference to System.Configuration.dll? ConfigurationManager class lies there.

EDIT: The System.Configuration namespace has classes in mscorlib.dll, system.dll and in system.configuration.dll. Your project always include the mscorlib.dll and system.dll references, but system.configuration.dll must be added to most project types, as it's not there by default...

API Documentation

According to the Android developers guide for android.hardware.Camera, they state:

We recommend using the new android.hardware.camera2 API for new applications.

On the information page about android.hardware.camera2, (linked above), it is stated:

The android.hardware.camera2 package provides an interface to individual camera devices connected to an Android device. It replaces the deprecated Camera class.

The problem

When you check that documentation you'll find that the implementation of these 2 Camera API's are very different.

For example getting camera orientation on android.hardware.camera

@Override
public int getOrientation(final int cameraId) {
    Camera.CameraInfo info = new Camera.CameraInfo();
    Camera.getCameraInfo(cameraId, info);
    return info.orientation;
}

Versus android.hardware.camera2

@Override
public int getOrientation(final int cameraId) {
    try {
        CameraManager manager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
        String[] cameraIds = manager.getCameraIdList();
        CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraIds[cameraId]);
        return characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
    } catch (CameraAccessException e) {
        // TODO handle error properly or pass it on
        return 0;
    }
}

This makes it hard to switch from one to another and write code that can handle both implementations.

Note that in this single code example I already had to work around the fact that the olde camera API works with int primitives for camera IDs while the new one works with String objects. For this example I quickly fixed that by using the int as an index in the new API. If the camera's returned aren't always in the same order this will already cause issues. Alternative approach is to work with String objects and String representation of the old int cameraIDs which is probably safer.

One away around

Now to work around this huge difference you can implement an interface first and reference that interface in your code.

Here I'll list some code for that interface and the 2 implementations. You can limit the implementation to what you actually use of the camera API to limit the amount of work.

In the next section I'll quickly explain how to load one or another.

The interface wrapping all you need, to limit this example I only have 2 methods here.

public interface CameraSupport {
    CameraSupport open(int cameraId);
    int getOrientation(int cameraId);
}

Now have a class for the old camera hardware api:

@SuppressWarnings("deprecation")
public class CameraOld implements CameraSupport {

    private Camera camera;

    @Override
    public CameraSupport open(final int cameraId) {
        this.camera = Camera.open(cameraId);
        return this;
    }

    @Override
    public int getOrientation(final int cameraId) {
       Camera.CameraInfo info = new Camera.CameraInfo();
       Camera.getCameraInfo(cameraId, info);
       return info.orientation;
    }
}

And another one for the new hardware api:

public class CameraNew implements CameraSupport {

    private CameraDevice camera;
    private CameraManager manager;

    public CameraNew(final Context context) {
        this.manager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
    }

    @Override
    public CameraSupport open(final int cameraId) {
        try {
            String[] cameraIds = manager.getCameraIdList();
            manager.openCamera(cameraIds[cameraId], new CameraDevice.StateCallback() {
                @Override
                public void onOpened(CameraDevice camera) {
                    CameraNew.this.camera = camera;
                }

                @Override
                public void onDisconnected(CameraDevice camera) {
                    CameraNew.this.camera = camera;
                    // TODO handle
                }

                @Override
                public void onError(CameraDevice camera, int error) {
                    CameraNew.this.camera = camera;
                    // TODO handle
                }
            }, null);
        } catch (Exception e) {
            // TODO handle
        }
        return this;
    }

    @Override
    public int getOrientation(final int cameraId) {
        try {
            String[] cameraIds = manager.getCameraIdList();
            CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraIds[cameraId]);
            return characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
        } catch (CameraAccessException e) {
            // TODO handle
            return 0;
        }
    }
}

Loading the proper API

Now to load either your CameraOld or CameraNew class you'll have to check the API level since CameraNew is only available from api level 21.

If you have dependency injection set up already you can do so in your module when providing the CameraSupport implementation. Example:

@Module public class CameraModule {

    @Provides
    CameraSupport provideCameraSupport(){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            return new CameraNew(context);
        } else {
            return new CameraOld();
        }
    } 
}

If you don't use DI you can just make a utility or use Factory pattern to create the proper one. Important part is that the API level is checked.

This will select empty text inputs with an id that starts with "txt":

Here's an extension function:

        {
            char[] buffer = new char[(((data.Length * 8) + (formatBits ? (data.Length - 1) : 0)))];
            int index = 0;
            for (int i = 0; i < data.Length; i++)
            {
                string binary = Convert.ToString(data[i], 2).PadLeft(8, '0');
                for (int j = 0; j < 8; j++)
                {
                    buffer[index] = binary[j];
                    index++;
                }
                if (formatBits && i < (data.Length - 1))
                {
                    buffer[index] = ' ';
                    index++;
                }
            }
            return new string(buffer);
        }

You can use it like:

Console.WriteLine("Testing".ToBinary());

and if you add 'true' as a parameter, it will automatically separate each binary sequence.

To change the stacking order for series in charts under Excel for Mac 2011:

1. select the chart,
2. select the series (easiest under Ribbon>Chart Layout>Current Selection),
3. click Chart Layout>Format Selection or Menu>Format>Data Series …,
4. on popup menu Format Data Series click Order, then click individual series and click Move Up or Move Down buttons to adjust the stacking order on the Axis for the subject series. This changes the order for the plot and for the legend, but may not change the order number in the Series formula.

I had a three series plot on the secondary axis, and the series I wanted on top was stuck on the bottom in defiance of the Move Up and Move Down buttons. It happened to be formatted as markers only. I inserted a line, and presto(!), I could change its order in the plot. Later I could remove the line and sometimes it could still be ordered, but sometimes not.

yes you can ;-)

                    $c = $t2[0]->getTimestamp();
                    $d = $t2[1]->getTimestamp();

                    if (($c >= $a && $c <= $b) || $d >= $a && $d <= $b) {

Sorry for ugly formatting. Just put a question character after declaration and everything will be ok. A question tells the compiler that the value is optional.

class Square: Shape {
    var sideLength: Double?   // <=== like this ..

    init(sideLength:Double, name:String) {
        super.init(name:name) // Error here
        self.sideLength = sideLength
        numberOfSides = 4
    }
    func area () -> Double {
        return sideLength * sideLength
    }
}

Edit1:

There is a better way to skip this error. According to jmaschad's comment there is no reason to use optional in your case cause optionals are not comfortable in use and You always have to check if optional is not nil before accessing it. So all you have to do is to initialize member after declaration:

class Square: Shape {
    var sideLength: Double=Double()   

    init(sideLength:Double, name:String) {
        super.init(name:name)
        self.sideLength = sideLength
        numberOfSides = 4
    }
    func area () -> Double {
        return sideLength * sideLength
    }
}

Edit2:

After two minuses got on this answer I found even better way. If you want class member to be initialized in your constructor you must assign initial value to it inside contructor and before super.init() call. Like this:

class Square: Shape {
    var sideLength: Double  

    init(sideLength:Double, name:String) {
        self.sideLength = sideLength   // <= before super.init call..
        super.init(name:name)
        numberOfSides = 4
    }
    func area () -> Double {
        return sideLength * sideLength
    }
}

Good luck in learning Swift.

Seems your selector is wrong, try using:

a.button:hover{
     background: #383;
}

Your code

a.button a:hover

Means it is going to search for an a element inside a with class button.

Two UE Boom Bluetooth speakers can form a stereo, which means the phone can stream simultaneously to two Bluetooth devices. The reason is Bluetooth 4.0 can support up to two synchronous connection oriented (SCO) links on the same piconet, and A2DP is based on SCO link.

Your demand "bluetooth chat" is based on SPP profile, and SPP is based on RFCOMM protocol. Luckily even Bluetooth 2.1 can support multiple RFCOMM channels, so yes, you can have multiple bluetooth connection to chat with each other.

I ran into this same issue trying to install the dbf package in Python 2.7. The problem is that the enum package wasn't added to Python until version 3.4.

It has been backported to versions 3.3, 3.2, 3.1, 2.7, 2.6, 2.5, and 2.4, you just need the package from here: https://pypi.python.org/pypi/enum34#downloads

Parameters take input before arguments. What you should do instead is add a parameter that accepts an array, and make it the first position parameter. ex:

param(
    [Parameter(Position = 0)]
    [string[]]$Hosts,
    [string]$VLAN
    )

foreach ($i in $Hosts)  
{ 
    Do-Stuff $i
}

Then call it like:

.\script.ps1 host1, host2, host3 -VLAN 2

Notice the comma between the values. This collects them in an array

I can't imagine everyone uses all 20 different keypresses to navigate text, 10 or so keys to start adding text, and 18 ways to visually select an inner block. Or do you!?

In theory, once I have that and start becoming as proficient in VIM as I am in Textmate, then I can start learning the thousands of other VIM commands that will make me more efficient.

That's the right way to do it. Start with basic commands and then pick up ones that improve your productivity. I like following this blog for tips on how to improve my productivity with vim.

When [dropping] the encoding settings mentioned above all characters [are rendered] correctly but the encoding that is detected shows either windows-1252 or ISO-8859-1 depending on the browser.

Then that's what you're really sending. None of the encoding settings in your bullet list will actually modify your output in any way; all they do is tell the browser what encoding to assume when interpreting what you send. That's why you're getting those ?s - you're telling the browser that what you're sending is UTF-8, but it's really ISO-8859-1.

string str = Properties.Settings.Default.myConnectionString;

I would counsel against using if ($hash{$key}) since it will not do what you expect if the key exists but its value is zero or empty.

I think there is another reason for wanting to set java.library.path. Subversion comes with many libraries and Eclipse won't see these unless java.library.path can be appended. For example I'm on OS-X, so the libraries are under \opt\subversion\lib. There are a lot of them and I'd like to keep them where they are (not copy them into a standard lib directory).

Project settings won't fix this.

It depends on what you are trying to do.

file, err := os.Open("file.txt")
fmt.print(file)

The reason it outputs &{0xc082016240}, is because you are printing the pointer value of a file-descriptor (*os.File), not file-content. To obtain file-content, you may READ from a file-descriptor.

To read all file content(in bytes) to memory, ioutil.ReadAll

package main

import (
    "fmt"
    "io/ioutil"
    "os"
    "log"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


  b, err := ioutil.ReadAll(file)
  fmt.Print(b)
}

But sometimes, if the file size is big, it might be more memory-efficient to just read in chunks: buffer-size, hence you could use the implementation of io.Reader.Read from *os.File

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


    buf := make([]byte, 32*1024) // define your buffer size here.

    for {
        n, err := file.Read(buf)

        if n > 0 {
            fmt.Print(buf[:n]) // your read buffer.
        }

        if err == io.EOF {
            break
        }
        if err != nil {
            log.Printf("read %d bytes: %v", n, err)
            break
        }
    }

}

Otherwise, you could also use the standard util package: bufio, try Scanner. A Scanner reads your file in tokens: separator.

By default, scanner advances the token by newline (of course you can customise how scanner should tokenise your file, learn from here the bufio test).

package main

import (
    "fmt"
    "os"
    "log"
    "bufio"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()

    scanner := bufio.NewScanner(file)

    for scanner.Scan() {             // internally, it advances token based on sperator
        fmt.Println(scanner.Text())  // token in unicode-char
        fmt.Println(scanner.Bytes()) // token in bytes

    }
}

Lastly, I would also like to reference you to this awesome site: go-lang file cheatsheet. It encompassed pretty much everything related to working with files in go-lang, hope you'll find it useful.

As mentioned in other answers you can use:

>> tic; x=5*ones(10,1); toc
Elapsed time is 0.000415 seconds.

An even faster method is:

>> tic;  x=5; x=x(ones(10,1)); toc
Elapsed time is 0.000257 seconds.

I thing ng-if should work:

<div ng-repeat="product in products" ng-if="product.color === 'red' 
|| product.color === 'blue'">

Without VBA...

If you can use a helper column, you can use the MATCH function to test if a value in one column exists in another column (or in another column on another worksheet). It will return an Error if there is no match

To simply identify duplicates, use a helper column

Assume data in Sheet1, Column A, and another list in Sheet2, Column A. In your helper column, row 1, place the following formula:

=If(IsError(Match(A1, 'Sheet2'!A:A,False)),"","Duplicate")

Drag/copy this forumla down, and it should identify the duplicates.

To highlight cells, use conditional formatting:

With some tinkering, you can use this MATCH function in a Conditional Formatting rule which would highlight duplicate values. I would probably do this instead of using a helper column, although the helper column is a great way to "see" results before you make the conditional formatting rule.

Something like:

=NOT(ISERROR(MATCH(A1, 'Sheet2'!A:A,FALSE)))

For Excel 2007 and prior, you cannot use conditional formatting rules that reference other worksheets. In this case, use the helper column and set your formatting rule in column A like:

=B1="Duplicate"

This screenshot is from the 2010 UI, but the same rule should work in 2007/2003 Excel.

This works best for me on OS X:

grep -r -l 'searchtext' . | sort | uniq | xargs perl -e "s/matchtext/replacetext/" -pi

The solution looks like great fun, but it is possible to concatenate arrays in just two statements. When you're handling large byte arrays, I suppose it is inefficient to use a Linked List to contain each byte.

Here is a code sample for reading bytes from a stream and extending a byte array on the fly:

    byte[] buf = new byte[8192];
    byte[] result = new byte[0];
    int count = 0;
    do
    {
        count = resStream.Read(buf, 0, buf.Length);
        if (count != 0)
        {
            Array.Resize(ref result, result.Length + count);
            Array.Copy(buf, 0, result, result.Length - count, count);
        }
    }
    while (count > 0); // any more data to read?
    resStream.Close();

To remove border you can use CSS border property to none.

<iframe src="myURL" width="300" height="300" style="border: none">Browser not compatible.</iframe>

You can also use scipy.signal.welch to estimate the power spectral density using Welch’s method. Here is an comparison between np.fft.fft and scipy.signal.welch:

from scipy import signal
import numpy as np
import matplotlib.pyplot as plt

fs = 10e3
N = 1e5
amp = 2*np.sqrt(2)
freq = 1234.0
noise_power = 0.001 * fs / 2
time = np.arange(N) / fs
x = amp*np.sin(2*np.pi*freq*time)
x += np.random.normal(scale=np.sqrt(noise_power), size=time.shape)

# np.fft.fft
freqs = np.fft.fftfreq(time.size, 1/fs)
idx = np.argsort(freqs)
ps = np.abs(np.fft.fft(x))**2
plt.figure()
plt.plot(freqs[idx], ps[idx])
plt.title('Power spectrum (np.fft.fft)')

# signal.welch
f, Pxx_spec = signal.welch(x, fs, 'flattop', 1024, scaling='spectrum')
plt.figure()
plt.semilogy(f, np.sqrt(Pxx_spec))
plt.xlabel('frequency [Hz]')
plt.ylabel('Linear spectrum [V RMS]')
plt.title('Power spectrum (scipy.signal.welch)')
plt.show()

Hera's the function UpdateWindowsList_WindowMenu() that you must call after any operations are performed on Tabs.Here windowToolStripMenuItem is the menu item added to Window Menu to menu strip.

public void UpdateWindowsList_WindowMenu()  
{  
    //get all tab pages from tabControl1  
    TabControl.TabPageCollection tabcoll = tabControl1.TabPages;  

    //get  windowToolStripMenuItem drop down menu items count  
    int n = windowToolStripMenuItem.DropDownItems.Count;  

    //remove all menu items from of windowToolStripMenuItem  
    for (int i = n - 1; i >=2; i--)  
    {  
        windowToolStripMenuItem.DropDownItems.RemoveAt(i);  
    }  

    //read each tabpage from tabcoll and add each tabpage text to windowToolStripMenuItem  
    foreach (TabPage tabpage in tabcoll)  
    {  
        //create Toolstripmenuitem  
        ToolStripMenuItem menuitem = new ToolStripMenuItem();  
        String s = tabpage.Text;  
        menuitem.Text = s;  

        if (tabControl1.SelectedTab == tabpage)  
        {  
            menuitem.Checked = true;  
        }  
        else  
        {  
            menuitem.Checked = false;  
        }  

        //add menuitem to windowToolStripMenuItem  
        windowToolStripMenuItem.DropDownItems.Add(menuitem);  

        //add click events to each added menuitem  
        menuitem.Click += new System.EventHandler(WindowListEvent_Click);  
    }  
}  

private void WindowListEvent_Click(object sender, EventArgs e)  
{  
    //casting ToolStripMenuItem to ToolStripItem  
    ToolStripItem toolstripitem = (ToolStripItem)sender;  

    //create collection of tabs of tabContro1  
    //check every tab text is equal to clicked menuitem then select the tab  
    TabControl.TabPageCollection tabcoll = tabControl1.TabPages;  
    foreach (TabPage tb in tabcoll)  
    {  
        if (toolstripitem.Text == tb.Text)  
        {  
            tabControl1.SelectedTab = tb;  
            //call UpdateWindowsList_WindowMenu() to perform changes on menuitems  
            UpdateWindowsList_WindowMenu();  
        }  
    }  
}  

To get both functions working for a clickable image that will respond to both short and long clicks, I tried the following that seems to work perfectly:

    image = (ImageView) findViewById(R.id.imageViewCompass);
    image.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            shortclick();
        }
     });

    image.setOnLongClickListener(new View.OnLongClickListener() {
    public boolean onLongClick(View v) {
        longclick();
        return true;
    }
});

//Then the functions that are called:

 public void shortclick()
{
 Toast.makeText(this, "Why did you do that? That hurts!!!", Toast.LENGTH_LONG).show();

}

 public void longclick()
{
 Toast.makeText(this, "Why did you do that? That REALLY hurts!!!", Toast.LENGTH_LONG).show();

}

It seems that the easy way of declaring the item in XML as clickable and then defining a function to call on the click only applies to short clicks - you must have a listener to differentiate between short and long clicks.

Found these docu on the google docu pages:

• row --- int --- top row of the range
• column --- int--- leftmost column of the range
• optNumRows --- int --- number of rows in the range.
• optNumColumns --- int --- number of columns in the range

In your example, you would get (if you picked the 3rd row) "C3:O3", cause C --> O is 12 columns

edit

Using the example on the docu:

// The code below will get the number of columns for the range C2:G8
// in the active spreadsheet, which happens to be "4"
var count = SpreadsheetApp.getActiveSheet().getRange(2, 3, 6, 4).getNumColumns(); Browser.msgBox(count);

The values between brackets:
2: the starting row = 2
3: the starting col = C
6: the number of rows = 6 so from 2 to 8
4: the number of cols = 4 so from C to G

So you come to the range: C2:G8

=$G1="X"

would be the correct (and easiest) method. Just select the entire sheet first, as conditional formatting only works on selected cells. I just tried it and it works perfectly. You must start at G1 rather than G2 otherwise it will offset the conditional formatting by a row.

You can use Janel. This last works as an application launcher or service launcher (available from 4.x).

Use the not boolean operator:

nyval = not myval

not returns a boolean value (True or False):

>>> not 1
False
>>> not 0
True

If you must have an integer, cast it back:

nyval = int(not myval)

However, the python bool type is a subclass of int, so this may not be needed:

>>> int(not 0)
1
>>> int(not 1)
0
>>> not 0 == 1
True
>>> not 1 == 0
True

SQL Wildcards are enough for this purpose. Follow this link: http://www.w3schools.com/SQL/sql_wildcards.asp

you need to use a query like this:

select * from mytable where msisdn like '%7%'

or

select * from mytable where msisdn like '56655%'

Very Simple Example is.

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd-MM-yyyy");
                Date date = new Date();
                Date date1 = new Date();
            try {
                System.out.println("Date1:   "+date1);
                System.out.println("date" + date);

                date = simpleDateFormat.parse("01-01-2013");
                date1 = simpleDateFormat.parse("06-15-2013");

                System.out.println("Date1 is:"+date1);
                System.out.println("date" + date);

            } catch (Exception e) {
                System.out.println(e.getMessage());
            }

Try one of these regular expressions:

// for numbers that need to start with a zero
[RegularExpression("([0-9]+)")] 


// for numbers that begin from 1
[RegularExpression("([1-9][0-9]*)")] 

hope it helps :D

You don't need to calculate anything, and probably shouldn't:

<!DOCTYPE html>
<head>
<style type="text/css">
    body {background: blue; height:100%;}
    header {background: red; height: 20px; width:100%}
    h1 {font-size:1.2em; margin:0; padding:0; 
        height: 30px; font-weight: bold; background:yellow}
    .theCalcDiv {background-color:green; padding-bottom: 100%}
</style>
</head>
<body>
<header>Some nav stuff here</header>
<h1>This is the heading</h1>
<div class="theCalcDiv">This blocks needs to have a CSS calc() height of 100% - the height of the other elements.
</div>

I stuck it all together for brevity.

Exporting each variable from your variables file. Then importing them with * as in your other file and exporting the as a constant from that file will give you a dynamic object with the named exports from the first file being attributes on the object exported from the second.

Variables.js

export const var1 = 'first';
export const var2 = 'second':
...
export const varN = 'nth';

Other.js

import * as vars from './Variables';

export const Variables = vars;

Third.js

import { Variables } from './Other';

Variables.var2 === 'second'

Updated for Apache 2.4, for non-systemd (e.g., CentOS 6.x, Amazon Linux AMI) and for systemd (e.g., CentOS 7.x):

There are two ways of having the apache process reload the configuration, depending on what you want done with its current threads, either advise to exit when idle, or killing them directly.

Note that Apache recommends using apachectl -k as the command, and for systemd, the command is replaced by httpd -k

apachectl -k graceful or httpd -k graceful

Apache will advise its threads to exit when idle, and then apache reloads the configuration (it doesn't exit itself), this means statistics are not reset.

apachectl -k restart or httpd -k restart

This is similar to stop, in that the process kills off its threads, but then the process reloads the configuration file, rather than killing itself.

Source: https://httpd.apache.org/docs/2.4/stopping.html

Without using 'length' you can do it like this:

if ($('input[type=checkbox]').is(":checked")) {
      //any one is checked
}
else {
//none is checked
}

It seems like it's a bug on Gradle. This solves the problem for me, but it's not a solution. We have to wait for a new version fixing this problems.

On build.gradle in the project set classpath 'com.android.tools.build:gradle:2.3.3' instead classpath 'com.android.tools.build:gradle:3.0.0'.

On gradle-wrapper.properties set https://services.gradle.org/distributions/gradle-3.3-all.zip instead https://services.gradle.org/distributions/gradle-4.1.2-all.zip

In you want to know the data from de selected row, you can try this snippet code:

DataGridView1.SelectedRows.Item(0).Cells(1).Value

Since the timestamps are seconds since the UNIX epoch, you can use DateTime.strptime ("string parse time") with the correct specifier:

Date.strptime('1100897479', '%s')
#=> #<Date: 2004-11-19 ((2453329j,0s,0n),+0s,2299161j)>
Date.strptime('1100897479', '%s').to_s
#=> "2004-11-19"
DateTime.strptime('1100897479', '%s')
#=> #<DateTime: 2004-11-19T20:51:19+00:00 ((2453329j,75079s,0n),+0s,2299161j)>
DateTime.strptime('1100897479', '%s').to_s
#=> "2004-11-19T20:51:19+00:00"

Note that you have to require 'date' for that to work, then you can call it either as Date.strptime (if you only care about the date) or DateTime.strptime (if you want date and time). If you need different formatting, you can call DateTime#strftime (look at strftime.net if you have a hard time with the format strings) on it or use one of the built-in methods like rfc822.

As of MySQL 5.6.5, you can use the DATETIME type with a dynamic default value:

CREATE TABLE foo (
    creation_time      DATETIME DEFAULT   CURRENT_TIMESTAMP,
    modification_time  DATETIME ON UPDATE CURRENT_TIMESTAMP
)

Or even combine both rules:

modification_time DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

Reference:
http://dev.mysql.com/doc/refman/5.7/en/timestamp-initialization.html
http://optimize-this.blogspot.com/2012/04/datetime-default-now-finally-available.html

Prior to 5.6.5, you need to use the TIMESTAMP data type, which automatically updates whenever the record is modified. Unfortunately, however, only one auto-updated TIMESTAMP field can exist per table.

CREATE TABLE mytable (
  mydate TIMESTAMP
)

See: http://dev.mysql.com/doc/refman/5.1/en/create-table.html

If you want to prevent MySQL from updating the timestamp value on UPDATE (so that it only triggers on INSERT) you can change the definition to:

CREATE TABLE mytable (
  mydate TIMESTAMP DEFAULT CURRENT_TIMESTAMP
)

Try this:

str.replace("\"", "\\\""); // (Escape backslashes and embedded double-quotes)

Or, use single-quotes to quote your search and replace strings:

str.replace('"', '\\"');   // (Still need to escape the backslash)

As pointed out by helmus, if the first parameter passed to .replace() is a string it will only replace the first occurrence. To replace globally, you have to pass a regex with the g (global) flag:

str.replace(/"/g, "\\\"");
// or
str.replace(/"/g, '\\"');

But why are you even doing this in JavaScript? It's OK to use these escape characters if you have a string literal like:

var str = "Dude, he totally said that \"You Rock!\"";

But this is necessary only in a string literal. That is, if your JavaScript variable is set to a value that a user typed in a form field you don't need to this escaping.

Regarding your question about storing such a string in an SQL database, again you only need to escape the characters if you're embedding a string literal in your SQL statement - and remember that the escape characters that apply in SQL aren't (usually) the same as for JavaScript. You'd do any SQL-related escaping server-side.

What operating system is this? The answer might depend on the OS involved. However, it looks like you need to find this BLAS library and install it. It doesn't seem to be in PIP (you'll have to do it by hand thus), but if you install it, it ought let you progress your SciPy install.

This gets the current working directory on Mac OS X v10.6.6 (Snow Leopard):

DIR=$(cd "$(dirname "$0")"; pwd)

I don't know if this helps but I just installed Server 2008 Express and was disappointed when I couldn't find the query analyzer but I was able to use the command line 'sqlcmd' to access my server. It is a pain to use but it works. You can write your code in a text file then import it using the sqlcmd command. You also have to end your query with a new line and type the word 'go'.

Example of query file named test.sql:
use master;
select name, crdate from sysdatabases where xtype='u' order by crdate desc;
go

Example of sqlcmd:
sqlcmd -S %computername%\RLH -d play -i "test.sql" -o outfile.sql & notepad outfile.sql

i used Mofi sample, and change some parameters, no you can do -t

@%SystemRoot%\system32\ping.exe -n -1 4.2.2.4

One way if you already know the package top level path is to use OpenPojo

final List<PojoClass> pojoClasses = PojoClassFactory.getPojoClassesRecursively("my.package.path", null);

Then you can go over the list and perform any functionality you desire.

subprocess.Popen takes a cwd argument to set the Current Working Directory; you'll also want to escape your backslashes ('d:\\test\\local'), or use r'd:\test\local' so that the backslashes aren't interpreted as escape sequences by Python. The way you have it written, the \t part will be translated to a tab.

So, your new line should look like:

subprocess.Popen(r'c:\mytool\tool.exe', cwd=r'd:\test\local')

To use your Python script path as cwd, import os and define cwd using this:

os.path.dirname(os.path.realpath(__file__)) 

Having the right CSS and JS libraries helps, this solved it for me

Using EntityManager em;

     return em.getReference(User.class, id);
}

I would recommend having a look at this answer of mine, and see if it is relevant to what you are doing. If I understand your real problem, it's that your just not using your async action correctly and updating the redux "store", which will automatically update your component with it's new props.

This section of your code:

componentDidMount() {
      if (this.props.isManager) {
        this.props.dispatch(actions.fetchAllSites())
      } else {
        const currentUserId = this.props.user.get('id')
        this.props.dispatch(actions.fetchUsersSites(currentUserId))
      }  
    }

Should not be triggering in a component, it should be handled after executing your first request.

Have a look at this example from redux-thunk:

function makeASandwichWithSecretSauce(forPerson) {

  // Invert control!
  // Return a function that accepts `dispatch` so we can dispatch later.
  // Thunk middleware knows how to turn thunk async actions into actions.

  return function (dispatch) {
    return fetchSecretSauce().then(
      sauce => dispatch(makeASandwich(forPerson, sauce)),
      error => dispatch(apologize('The Sandwich Shop', forPerson, error))
    );
  };
}

You don't necessarily have to use redux-thunk, but it will help you reason about scenarios like this and write code to match.

You will be much happier using a dictionary instead:

my_data = {}
foo = "hello"
my_data[foo] = "goodbye"
assert my_data["hello"] == "goodbye"

There is Effort which is an in memory entity framework database provider. I've not actually tried it... Haa just spotted this was mentioned in the question!

Alternatively you could switch to EntityFrameworkCore which has an in memory database provider built-in.

I used a factory to get a context, so i can create the context close to its use. This seems to work locally in visual studio but not on my TeamCity build server, not sure why yet.

return new MyContext(@"Server=(localdb)\mssqllocaldb;Database=EFProviders.InMemory;Trusted_Connection=True;");

You can actually simplify this by removing the v-on directives:

<input type="radio" name="optionsRadios" id="optionsRadios1" value="1" v-model="srStatus">

And use the watch method to listen for the change:

new Vue ({
    el: "#app",
    data: {
        cases: [
            { name: 'case A', status: '1' },
            { name: 'case B', status: '0' },
            { name: 'case C', status: '1' }
        ],
        activeCases: [],
        srStatus: ''
    },
    watch: {
        srStatus: function(val, oldVal) {
            for (var i = 0; i < this.cases.length; i++) {
                if (this.cases[i].status == val) {
                    this.activeCases.push(this.cases[i]);
                    alert("Fired! " + val);
                }
            }
        }
    }
});

Steps that you should follow if you want the thread dump of your StandAlone Java Process

Step 1: Get the Process ID for the shell script calling the java program

linux$ ps -aef | grep "runABCD"

user1  **8535**  4369   0   Mar 25 ?           0:00 /bin/csh /home/user1/runABCD.sh

user1 17796 17372   0 08:15:41 pts/49      0:00 grep runABCD

Step 2: Get the Process ID for the Child which was Invoked by the runABCD. Use the above PID to get the childs.

linux$ ps -aef | grep **8535**

user1  **8536**  8535   0   Mar 25 ?         126:38 /apps/java/jdk/sun4/SunOS5/1.6.0_16/bin/java -cp /home/user1/XYZServer

user1  8535  4369   0   Mar 25 ?           0:00 /bin/csh /home/user1/runABCD.sh

user1 17977 17372   0 08:15:49 pts/49      0:00 grep 8535

Step 3: Get the JSTACK for the particular process. Get the Process id of your XYSServer process. i.e. 8536

linux$ jstack **8536** > threadDump.log

The browser is still submitting the form after your code runs.

Add return false; to the handler to prevent that.

Also the visual studio add-in ghost doc will attempt to create and fill-in the header comments from your function name.

You need to convert the date into a readable value. You may use strftime() or date().

Try this:

$effectiveDate = strtotime("+3 months", strtotime($effectiveDate));
$effectiveDate = strftime ( '%Y-%m-%d' , $effectiveDate );
echo $effectiveDate;

This should work. I like using strftime better as it can be used for localization you might want to try it.

Have you tried running $("#estado_cat").checkboxradio("refresh") on your checkbox?

You are using the wrong format tokens when parsing your input. You should use ddd for an abbreviation of the name of day of the week, DD for day of the month, MMM for an abbreviation of the month's name, YYYY for the year, hh for the 1-12 hour, mm for minutes and A for AM/PM. See moment(String, String) docs.

Here is a working live sample:

console.log( moment('Mon 03-Jul-2017, 11:00 AM', 'ddd DD-MMM-YYYY, hh:mm A').format('hh:mm A') );_x000D_
console.log( moment('Mon 03-Jul-2017, 11:00 PM', 'ddd DD-MMM-YYYY, hh:mm A').format('hh:mm A') );

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.min.js"></script>

def getUser(self, id, Email):

    user_key = id and id or Email

    assert user_key

Can be used to ensure parameters are passed in the function call.

Normally, when the user tabs from field to field in a form (in a browser that allows tabbing, not all browsers do) the order is the order the fields appear in the HTML code.

However, sometimes you want the tab order to flow a little differently. In that case, you can number the fields using TABINDEX. The tabs then flow in order from lowest TABINDEX to highest.

More info on this can be found here w3

another good illustration can be found here

You have to edit the Security Group to which your EC2 instance belongs and allow access (or alternatively create a new one and add the instance to it).

By default everything is denied. The exception you need to add to the Security Group depends on the service you need to make available to the internet.

If it is a webserver you will need to allow access to port 80 for 0.0.0.0/0 (which means any IP address).

To allow pinging the instance you need to enable ICMP traffic.

The AWS Web Console provides some of the most commonly used options in the relevant dropdown list.

To expand on Trevor's answer, you can push a single tag or all of your tags at once.

Push a Single Tag

git push <remote> <tag>

This is a summary of the relevant documentation that explains this (some command options omitted for brevity):

git push [[<repository> [<refspec>…]]

<refspec>...

The format of a <refspec> parameter is…the source ref <src>, followed by a colon :, followed by the destination ref <dst>…

The <dst> tells which ref on the remote side is updated with this push…If :<dst> is omitted, the same ref as <src> will be updated…

tag <tag> means the same as refs/tags/<tag>:refs/tags/<tag>.

Push All of Your Tags at Once

git push --tags <remote>
# Or
git push <remote> --tags

Here is a summary of the relevant documentation (some command options omitted for brevity):

git push [--all | --mirror | --tags] [<repository> [<refspec>…]]

--tags

All refs under refs/tags are pushed, in addition to refspecs explicitly listed on the command line.

All are good answers explaining why you cannot modify string literals because they are placed in read-only memory. However, when push comes to shove, there is a way to do this. Check out this example:

#include <sys/mman.h>
#include <unistd.h>
#include <stddef.h>
#include <string.h>
#include <stdlib.h>
#include <stdio.h>

int take_me_back_to_DOS_times(const void *ptr, size_t len);

int main()
{
    const *data = "Bender is always sober.";
    printf("Before: %s\n", data);
    if (take_me_back_to_DOS_times(data, sizeof(data)) != 0)
        perror("Time machine appears to be broken!");
    memcpy((char *)data + 17, "drunk!", 6);
    printf("After: %s\n", data);

    return 0;
}

int take_me_back_to_DOS_times(const void *ptr, size_t len)
{
    int pagesize;
    unsigned long long pg_off;
    void *page;

    pagesize = sysconf(_SC_PAGE_SIZE);
    if (pagesize < 0)
        return -1;
    pg_off = (unsigned long long)ptr % (unsigned long long)pagesize;

    if (mprotect(page, len + pg_off, PROT_READ | PROT_WRITE | PROT_EXEC) == -1)
        return -1;
    return 0;
}

I have written this as part of my somewhat deeper thoughts on const-correctness, which you might find interesting (I hope :)).

Hope it helps. Good Luck!

I have included this code in my /etc/apache2/apache2.conf

Sometimes your json is not a string. For example if you are getting a json from a url like this:

j = urllib2.urlopen('http://site.com/data.json')

you will need to use json.load, not json.loads:

j_obj = json.load(j)

(it is easy to forget: the 's' is for 'string')

To stop the service we must use the method stopService():

  Intent myService = new Intent(MainActivity.this, BackgroundSoundService.class);
  //startService(myService);
  stopService(myService);

then the method onDestroy() in the service is called:

  @Override
    public void onDestroy() {

        Log.i(TAG, "onCreate() , service stopped...");
    }

Here is a complete example including how to stop the service.

As explained in the documentation, by using an @RequestParam annotation:

public @ResponseBody String byParameter(@RequestParam("foo") String foo) {
    return "Mapped by path + method + presence of query parameter! (MappingController) - foo = "
           + foo;
}

Use a case statement:

select id,
    case report.type
        when 'P' then amount
        when 'N' then -amount
    end as amount
from
    `report`

Gold Noise

// Gold Noise ©2015 [email protected]
// - based on the Golden Ratio
// - uniform normalized distribution
// - fastest static noise generator function (also runs at low precision)

float PHI = 1.61803398874989484820459;  // F = Golden Ratio   

float gold_noise(in vec2 xy, in float seed){
       return fract(tan(distance(xy*PHI, xy)*seed)*xy.x);
}

See Gold Noise in your browser right now!

This function has improved random distribution over the current function in @appas' answer as of Sept 9, 2017:

The @appas function is also incomplete, given there is no seed supplied (uv is not a seed - same for every frame), and does not work with low precision chipsets. Gold Noise runs at low precision by default (much faster).

Simple SQL triggered API call without building a code project

I know this is far from perfect or architectural purity, but I had a customer with a short term, critical need to integrate with a third party product via an immature API (no wsdl) I basically needed to call the API when a database event occurred. I was given basic call info - URL, method, data elements and Token, but no wsdl or other start to import into a code project. All recommendations and solutions seemed start with that import.

I used the ARC (Advanced Rest Client) Chrome extension and JaSON to test the interaction with the Service from a browser and refine the call. That gave me the tested, raw call structure and response and let me play with the API quickly. From there, I started trying to generate the wsdl or xsd from the json using online conversions but decided that was going to take too long to get working, so I found cURL (clouds part, music plays). cURL allowed me to send the API calls to a local manager from anywhere. I then broke a few more design rules and built a trigger that queued the DB events and a SQL stored procedure and scheduled task to pass the parameters to cURL and make the calls. I initially had the trigger calling XP_CMDShell (I know, booo) but didn't like the transactional implications or security issues, so switched to the Stored Procedure method.

In the end, DB insert matching the API call case triggers write to Queue table with parameters for API call Stored procedure run every 5 seconds runs Cursor to pull each Queue table entry, send the XP_CMDShell call to the bat file with parameters Bat file contains Curl call with parameters inserted sending output to logs. Works well.

Again, not perfect, but for a tight timeline, and a system used short term, and that can be closely monitored to react to connectivity and unforeseen issues, it worked.

Hope that helps someone struggling with limited API info get a solution going quickly.

Vince Yuan's code is great but it seems to be something wrong.

function download(url, dest, callback) {
    var file = fs.createWriteStream(dest);
    var request = http.get(url, function (response) {
        response.pipe(file);
        file.on('finish', function () {
            file.close(callback); // close() is async, call callback after close completes.
        });
        file.on('error', function (err) {
            fs.unlink(dest); // Delete the file async. (But we don't check the result)
            if (callback)
                callback(err.message);
        });
    });
}

I had this same problem on a Windows machine. When I ran a git pull origin master command, I would get the "ahead of 'origin/master' by X commits" warning. I found that if I instead ran git pull origin and did NOT specify the branch, then I would no longer receive the warning.

Sometimes you want to pass all your arguments, but preceded by a flag (e.g. --flag)

$ bar --flag "$1" --flag "$2" --flag "$3"

You can do this in the following way:

$ bar $(printf -- ' --flag "%s"' "$@")

note: to avoid extra field splitting, you must quote %s and $@, and to avoid having a single string, you cannot quote the subshell of printf.

I created multiple threads in Python, I printed the thread objects, and I printed the id using the ident variable. I see all the ids are same:

<Thread(Thread-1, stopped 140500807628544)>
<Thread(Thread-2, started 140500807628544)>
<Thread(Thread-3, started 140500807628544)>

Ted's answer is amazing. I ended up using a smaller version of that in case anyone is interested. Useful when you are looking for one aggregation that depends on values from multiple columns:

create a dataframe

df=pd.DataFrame({'a': [1,2,3,4,5,6], 'b': [1,1,0,1,1,0], 'c': ['x','x','y','y','z','z']})


   a  b  c
0  1  1  x
1  2  1  x
2  3  0  y
3  4  1  y
4  5  1  z
5  6  0  z

grouping and aggregating with apply (using multiple columns)

df.groupby('c').apply(lambda x: x['a'][(x['a']>1) & (x['b']==1)].mean())

c
x    2.0
y    4.0
z    5.0

grouping and aggregating with aggregate (using multiple columns)

I like this approach since I can still use aggregate. Perhaps people will let me know why apply is needed for getting at multiple columns when doing aggregations on groups.

It seems obvious now, but as long as you don't select the column of interest directly after the groupby, you will have access to all the columns of the dataframe from within your aggregation function.

only access to the selected column

df.groupby('c')['a'].aggregate(lambda x: x[x>1].mean())

access to all columns since selection is after all the magic

df.groupby('c').aggregate(lambda x: x[(x['a']>1) & (x['b']==1)].mean())['a']

or similarly

df.groupby('c').aggregate(lambda x: x['a'][(x['a']>1) & (x['b']==1)].mean())

I hope this helps.

str = "M" + str.Substring(1);

If you'll do several such changes use a StringBuilder or a char[].

(The threshold of when StringBuilder becomes quicker is after about 5 concatenations or substrings, but note that grouped concatenations of a + "b" + c + d + "e" + f are done in a single call and compile-type concatenations of "a" + "b" + "c" don't require a call at all).

It may seem that having to do this is horribly inefficient, but the fact that strings can't be changes allows for lots of efficiency gains and other advantages such as mentioned at Why .NET String is immutable?

Is maching set to CASE_INSENSITIVE?

For me, in our work environment, we have Windows 7 64-bit with the machines locked down running McAfee with Host Intrusion turned on.

I turned off Host Intrusion and gradle would finally work, so definitely, it appears to be issues with certain Virus scanners.

UPDATE: Well I spoke too soon. Yes, I know longer get the "Unable to start the daemon process" message, but now I get the following:

Error:Could not list versions using M2 pattern 'http://jcenter.bintray.com/[organisation]/[module]/[revision]/[artifact]-revision.[ext]'.
