Programs & Examples On #Mysql error 1136

I kept getting same error again and again,

Finally I uploaded the apk file manually using Google Play Console as shown in screen shot.

Under App Release, You select the button "CREATE RELEASE" shown in the screen shot and upload your apk file from /android/app/bin/build/outputs/apk/release/app-release.apk

When I disabled ReSharper, Visual Studio was also giving the same error, even though the project built successfully. What I did to resolve the issue was:

1. Remove the project from the solution.
2. Right-click the solution, Add Existing Project, select the project file and add it again.

After performing these steps, the syntax errors went away in Visual Studio, and after I enabled ReSharper again, it also had no errors.

encodeURIComponent(string) will do it:

encodeURIComponent("Robert'); DROP TABLE Students;--")
//>> "Robert')%3B%20DROP%20TABLE%20Students%3B--"

Passing SQL around in a query string might not be a good plan though,

see this one

Try to see, if the service "SQL Server (MSSQLSERVER)" it's started, this solved my problem.

Hey I had the same problem. I tried to convert '2017-02-20 12:15:32' varchar to a date with TO_DATE('2017-02-20 12:15:32','YYYY-MM-DD HH24:MI:SS') and all I received was 2017-02-20 the time disappeared

My solution was to use TO_TIMESTAMP('2017-02-20 12:15:32','YYYY-MM-DD HH24:MI:SS') now the time doesn't disappear.

This could also be done :

$("#myTable > tbody").html($("#myTable > tbody").html()+"<tr><td>my data</td><td>more data</td></tr>")

removing temp files, and did you restart the computer or stop the MySQL service? That's the error message you get when there isn't a MySQL server running.

Yes, this is correct, but it looks like a very basic workflow, where you're just buffering changes before they're ready for integration. You should look into more advanced workflows that git supports. You might like the topic branch approach, which lets you work on multiple features in parallel, or the graduation approach which extends your current workflow a bit.

The usual way to test for a NaN is to see if it's equal to itself:

def isNaN(num):
    return num != num

Here is the simple version

 #one
 a = [[0]*10]*10

 #two
row, col = 10, 10
a = [[0]*row]*col

None of these answers seem to completely address the question, which calls for an arbitrary url, not specifically the url of the current page.

Method 1: Use the URL API (caveat: no IE11 support)

You can use the URL API (not supported by IE11, but available everywhere else).

This also makes it easy to access search params. Another bonus: it can be used in a Web Worker since it doesn't depend on the DOM.

const url = new URL('http://example.com:12345/blog/foo/bar?startIndex=1&pageSize=10');

Method 2 (old way): Use the browser's built-in parser in the DOM

Use this if you need this to work on older browsers as well.

//  Create an anchor element (note: no need to append this element to the document)
const url = document.createElement('a');
//  Set href to any path
url.setAttribute('href', 'http://example.com:12345/blog/foo/bar?startIndex=1&pageSize=10');

That's it!

The browser's built-in parser has already done its job. Now you can just grab the parts you need (note that this works for both methods above):

//  Get any piece of the url you're interested in
url.hostname;  //  'example.com'
url.port;      //  12345
url.search;    //  '?startIndex=1&pageSize=10'
url.pathname;  //  '/blog/foo/bar'
url.protocol;  //  'http:'

Bonus: Search params

Chances are you'll probably want to break apart the search url params as well, since '?startIndex=1&pageSize=10' isn't too useable on its own.

If you used Method 1 (URL API) above, you simply use the searchParams getters:

url.searchParams.get('startIndex');  // '1'

Or to get all parameters:

function searchParamsToObj(searchParams) {
  const paramsMap = Array
    .from(url.searchParams)
    .reduce((params, [key, val]) => params.set(key, val), new Map());
  return Object.fromEntries(paramsMap);
}
searchParamsToObj(url.searchParams);
// -> { startIndex: '1', pageSize: '10' }

If you used Method 2 (the old way), you can use something like this:

// Simple object output (note: does NOT preserve duplicate keys).
var params = url.search.substr(1); // remove '?' prefix
params
    .split('&')
    .reduce((accum, keyval) => {
        const [key, val] = keyval.split('=');
        accum[key] = val;
        return accum;
    }, {});
// -> { startIndex: '1', pageSize: '10' }

request.FILES['filename'].name

From the request documentation.

If you don't know the key, you can iterate over the files:

for filename, file in request.FILES.iteritems():
    name = request.FILES[filename].name

For this use below code in your app gradle file under android closure.

dexOptions { javaMaxHeapSize "4g" }

For those that want a nice conditional:

DECLARE @MyDate DATETIME  = 'some date in future' --example  DateAdd(day,5,GetDate())

IF @MyDate < DATEADD(DAY,1,GETDATE())
    BEGIN
        PRINT 'Date NOT greater than today...'
END
ELSE 
    BEGIN
       PRINT 'Date greater than today...'
END 

This does not answer the question fully, but for anyone who is able to calculate the number of days by which they would like to offset an initial date then the following method will work:

myDate.setUTCDate(myDate.getUTCDate() + offsetDays);

offsetDays can be positive or negative and the result will be correct for any given initial date with any given offset.

The number of column parameters in your insert query is 9, but you've only provided 8 values.

INSERT INTO dbname (id, Name, Description, shortDescription, Ingredients, Method, Length, dateAdded, Username) VALUES ('', '%s', '%s', '%s', '%s', '%s', '%s', '%s')

The query should omit the "id" parameter, because it is auto-generated (or should be anyway):

INSERT INTO dbname (Name, Description, shortDescription, Ingredients, Method, Length, dateAdded, Username) VALUES ('', '%s', '%s', '%s', '%s', '%s', '%s', '%s')

Yes, you can do this by creating a DoubleStream from the array, filtering out the negatives, and converting the stream back to an array. Here is an example:

double[] d = {8, 7, -6, 5, -4};
d = Arrays.stream(d).filter(x -> x > 0).toArray();
//d => [8, 7, 5]

If you want to filter a reference array that is not an Object[] you will need to use the toArray method which takes an IntFunction to get an array of the original type as the result:

String[] a = { "s", "", "1", "", "" };
a = Arrays.stream(a).filter(s -> !s.isEmpty()).toArray(String[]::new);

If you are using C++ 17 you can just use the inline specifier (see https://stackoverflow.com/a/11711082/55721)

If using older versions of the C++ standard, you must add the definitions to match your declarations of X and Y

unsigned char test::X;
unsigned char test::Y;

somewhere. You might want to also initialize a static member

unsigned char test::X = 4;

and again, you do that in the definition (usually in a CXX file) not in the declaration (which is often in a .H file)

First check to see if the string's length needs to be shortened, then add spaces until it is as long as the field length.

fieldLength = 15
string1 = string1[0:15] # If it needs to be shortened, shorten it
while len(string1) < fieldLength:
    rand += " "

faster to read than non cluster as data is physically storted in index order we can create only one per table.(cluster index)

quicker for insert and update operation than a cluster index. we can create n number of non cluster index.

Note that some time ago there was an update to this command. It will not show the container size by default (since this is rather expensive for many running containers). Use docker ps -s to display container size as well.

To remove you tube controls and title you can do something like this.

<iframe width="560" height="315" src="https://www.youtube.com/embed/zP0Wnb9RI9Q?autoplay=1&showinfo=0&controls=0" frameborder="0" allowfullscreen ></iframe>

check this example how it look

showinfo=0 is used to remove title and &controls=0 is used for remove controls like volume,play,pause,expend.

I ran into this same issue trying to deploy my MVC3 Razor web application on GoDaddy shared hosting. There are some additional .dlls that need to be referenced. Details here: http://paulmason.biz/?p=108

Basically you need to add references to the following in addition to the ones listed in @Haacked's post and set them to deploy locally as described.

• Microsoft.Web.Infrastructure
• System.Web.Razor
• System.Web.WebPages.Deployment
• System.Web.WebPages.Razor

I tried all the options above and none worked. This is what I did that worked :

@{
    string str = @"[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,3}$";
}

<td>Email</td>
<td>
   <input type="text" id="txtEmail" required name="email" pattern=@str /> 
</td>

I created a string varible and passed all the RegEx pattern code into it, then used the variable in the html, and Razor was cool with it.

It seems the closest is:

apt-cache policy

Don't know if you still need an answer to this but I found from my limited (3 weeks worth of self-teaching R) experience with R that, using the NULL assignment is actually wrong or sub-optimal especially if you're dynamically updating a list in something like a for-loop.

To be more precise, using

myList[[5]] <- NULL

will throw the error

myList[[5]] <- NULL : replacement has length zero

or

more elements supplied than there are to replace

What I found to work more consistently is

myList <- myList[[-5]]

app.factory('persistObject', function () {

        var persistObject = [];

        function set(objectName, data) {
            persistObject[objectName] = data;
        }
        function get(objectName) {
            return persistObject[objectName];
        }

        return {
            set: set,
            get: get
        }
    });

Fill it with data like this

persistObject.set('objectName', data); 

Get the object data like this

persistObject.get('objectName'); 

What is your output when you do java -version? This will tell you what version the running JVM is.

The Unsupported major.minor version 51.0 error could mean:

• Your server is running a lower Java version then the one used to compile your Servlet and vice versa

Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)

See: http://www.java.com/en/download/manual.jsp (7 Update 25 )

and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)

for the latest version of the JRE and JDK respectively.

EDIT:

Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.

Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.

You want something more like this:

SELECT TableA.*, TableB.*, TableC.*, TableD.*
FROM TableA
    JOIN TableB
        ON TableB.aID = TableA.aID
    JOIN TableC
        ON TableC.cID = TableB.cID
    JOIN TableD
        ON TableD.dID = TableA.dID
WHERE DATE(TableC.date)=date(now()) 

In your example, you are not actually including TableD. All you have to do is perform another join just like you have done before.

A note: you will notice that I removed many of your parentheses, as they really are not necessary in most of the cases you had them, and only add confusion when trying to read the code. Proper nesting is the best way to make your code readable and separated out.

This sometimes does not work if Eclipse is on one of those strange default windows paths (e.g. c:/Program files (86)/Eclipse).

In that case, do as above, then move the lombok jar to a cleaner path without spaces and braces (e.g. c:\lombok\lombok.jar) and modify eclipse.ini accordingly.

Just thought that we'd throw in our solution too as we had the exact same problem on Chrome/Windows.

We tried the solution by @stevenWatkins above, but still had the "stepping".

Instead of

-webkit-backface-visibility: hidden;

We used:

-webkit-backface-visibility: initial;

For us this did the trick

Alternative to @Peter Monks.

If the number in the 'in' statement is small and fixed.

DECLARE @var1 varchar(30), @var2 varchar(30), @var3  varchar(30);

SET @var1 = 'james';
SET @var2 = 'same';
SET @var3 = 'dogcat';

Select * FROM Database Where x in (@var1,@var2,@var3);

There is a problem with every answer provided that can be summarized as "just add this magical incantation to the beginning of your script. See what you can do with just a line or two of code." They will not work in every possible situation!

For example, one such magical incantation uses __file__. Unfortunately, if you package your script using cx_Freeze or you are using IDLE, this will result in an exception.

Another such magical incantation uses os.getcwd(). This will only work if you are running your script from the command prompt and the directory containing your script is the current working directory (that is you used the cd command to change into the directory prior to running the script). Eh gods! I hope I do not have to explain why this will not work if your Python script is in the PATH somewhere and you ran it by simply typing the name of your script file.

Fortunately, there is a magical incantation that will work in all the cases I have tested. Unfortunately, the magical incantation is more than just a line or two of code.

import inspect
import os
import sys

# Add script directory to sys.path.
# This is complicated due to the fact that __file__ is not always defined.

def GetScriptDirectory():
    if hasattr(GetScriptDirectory, "dir"):
        return GetScriptDirectory.dir
    module_path = ""
    try:
        # The easy way. Just use __file__.
        # Unfortunately, __file__ is not available when cx_Freeze is used or in IDLE.
        module_path = __file__
    except NameError:
        if len(sys.argv) > 0 and len(sys.argv[0]) > 0 and os.path.isabs(sys.argv[0]):
            module_path = sys.argv[0]
        else:
            module_path = os.path.abspath(inspect.getfile(GetScriptDirectory))
            if not os.path.exists(module_path):
                # If cx_Freeze is used the value of the module_path variable at this point is in the following format.
                # {PathToExeFile}\{NameOfPythonSourceFile}. This makes it necessary to strip off the file name to get the correct
                # path.
                module_path = os.path.dirname(module_path)
    GetScriptDirectory.dir = os.path.dirname(module_path)
    return GetScriptDirectory.dir

sys.path.append(os.path.join(GetScriptDirectory(), "lib"))
print(GetScriptDirectory())
print(sys.path)

As you can see, this is no easy task!

So, let's say you have this table:

CREATE TABLE YourTable(Col1 VARCHAR(10))

And you want to change Col1 to VARCHAR(20). What you need to do is this:

ALTER TABLE YourTable
ALTER COLUMN Col1 VARCHAR(20)

That'll work without problems since the length of the column got bigger. If you wanted to change it to VARCHAR(5), then you'll first gonna need to make sure that there are not values with more chars on your column, otherwise that ALTER TABLE will fail.

You are wrong about LocalDateTime: it does not store any time-zone information and it has nanosecond precision. Quoting the Javadoc (emphasis mine):

A date-time without a time-zone in the ISO-8601 calendar system, such as 2007-12-03T10:15:30.

LocalDateTime is an immutable date-time object that represents a date-time, often viewed as year-month-day-hour-minute-second. Other date and time fields, such as day-of-year, day-of-week and week-of-year, can also be accessed. Time is represented to nanosecond precision. For example, the value "2nd October 2007 at 13:45.30.123456789" can be stored in a LocalDateTime.

The difference between the two is that Instant represents an offset from the Epoch (01-01-1970) and, as such, represents a particular instant on the time-line. Two Instant objects created at the same moment in two different places of the Earth will have exactly the same value.

Do this :

$(document).ready(function(){
     $("#frm1").submit();
});

If we have:

enum Gender
{
    M = 0,
    F = 1,
    U = 2
}

and

enum Gender2
{
    Male = 0,
    Female = 1,
    Unknown = 2
}

We can safely do

var gender = Gender.M;
var gender2   = (Gender2)(int)gender;

Or even

var enumOfGender2Type = (Gender2)0;

If you want to cover the case where an enum on the right side of the '=' sign has more values than the enum on the left side - you will have to write your own method/dictionary to cover that as others suggested.

I just realized that it's not enough to put a comment on p4bl0's answer, though Tom's answer clearly solves the problem:

return filename.replace(/^.*?\.([a-zA-Z0-9]+)$/, "$1");

$scope has a different 'this' then the controller 'this'.Thus if you put a console.log(this) inside controller it gives you a object(controller) and this.addPane() adds addPane Method to the controller Object. But the $scope has different scope and all method in its scope need to be accesed by $scope.methodName(). this.methodName() inside controller means to add methos inside controller object.$scope.functionName() is in HTML and inside

$scope.functionName(){
    this.name="Name";
    //or
    $scope.myname="myname"//are same}

In iOS 9.2 they renamed the 'Profiles' to 'Device Management'

This is how you should do it now:

1. Settings -> General -> Device Management
2. Verify the app

It looks like this issue has to do with the difference between the Content-Type and Accept headers. In HTTP, Content-Type is used in request and response payloads to convey the media type of the current payload. Accept is used in request payloads to say what media types the server may use in the response payload.

So, having a Content-Type in a request without a body (like your GET request) has no meaning. When you do a POST request, you are sending a message body, so the Content-Type does matter.

If a server is not able to process the Content-Type of the request, it will return a 415 HTTP error. (If a server is not able to satisfy any of the media types in the request Accept header, it will return a 406 error.)

In OData v3, the media type "application/json" is interpreted to mean the new JSON format ("JSON light"). If the server does not support reading JSON light, it will throw a 415 error when it sees that the incoming request is JSON light. In your payload, your request body is verbose JSON, not JSON light, so the server should be able to process your request. It just doesn't because it sees the JSON light content type.

You could fix this in one of two ways:

1. Make the Content-Type "application/json;odata=verbose" in your POST request, or

2. Include the DataServiceVersion header in the request and set it be less than v3. For example:

   DataServiceVersion: 2.0;
   

(Option 2 assumes that you aren't using any v3 features in your request payload.)

There's no real need to initialize to smallest/largest possible to find the smallest/largest in the array:

double largest = smallest = array[0];
for (int i=1; i<array_size; i++) {
    if (array[i] < smallest)
        smallest = array[i];
    if (array[i] > largest0
        largest= array[i];
}

Or, if you're doing it more than once:

#include <utility>

template <class iter>
std::pair<typename iter::value_type, typename iter::value_type> find_extrema(iter begin, iter end) {
    std::pair<typename iter::value_type, typename iter::value_type> ret;
    ret.first = ret.second = *begin;
    while (++begin != end) {
        if (*begin < ret.first)
           ret.first = *begin;
        if (*begin > ret.second)
           ret.second = *begin;
   }
   return ret;
}

The disadvantage of providing sample code -- I see others have already suggested the same idea.

Note that while the standard has a min_element and max_element, using these would require scanning through the data twice, which could be a problem if the array is large at all. Recent standards have addressed this by adding a std::minmax_element, which does the same as the find_extrema above (find both the minimum and maximum elements in a collection in a single pass).

Edit: Addressing the problem of finding the smallest non-zero value in an array of unsigned: observe that unsigned values "wrap around" when they reach an extreme. To find the smallest non-zero value, we can subtract one from each for the comparison. Any zero values will "wrap around" to the largest possible value for the type, but the relationship between other values will be retained. After we're done, we obviously add one back to the value we found.

unsigned int min_nonzero(std::vector<unsigned int> const &values) { 
    if (vector.size() == 0)
        return 0;
    unsigned int temp = values[0]-1;
    for (int i=1; i<values.size(); i++)
        if (values[i]-1 < temp)
            temp = values[i]-1;
    return temp+1;
}

Note this still uses the first element for the initial value, but we still don't need any "special case" code -- since that will wrap around to the largest possible value, any non-zero value will compare as being smaller. The result will be the smallest nonzero value, or 0 if and only if the vector contained no non-zero values.

It should be noted that you can export a variable and later change the value. The variable's changed value will be available to child processes. Once export has been set for a variable you must do export -n <var> to remove the property.

$ K=1
$ export K
$ K=2
$ bash -c 'echo ${K-unset}'
2
$ export -n K
$ bash -c 'echo ${K-unset}'
unset

Life is simple if you get a good web framework. Web services in Django are easy. Define your model, write view functions that return your CSV documents. Skip the templates.

I ran into this problem and fixed it by closing the input and output streams before closing the socket. Now I can disconnect and connect again with no issues.

https://stackoverflow.com/a/3039807/5688612

In Kotlin:

fun disconnect() {
    bluetoothSocket.inputStream.close()
    bluetoothSocket.outputStream.close()
    bluetoothSocket.close()
}

I tried to use the \x00 and it didn't work for me when using C# and Regex. I had success with the following:

//The hexidecimal 0x0 is the null character  
mystring.Contains(Convert.ToChar(0x0).ToString() );  

// This will replace the character
mystring = mystring.Replace(Convert.ToChar(0x0).ToString(), "");  

If @Cybernate's solution doesn't work, try breaking the trigger off in to it's own function so you can reference it.

clickHandler = function(event){
  if (click++ == 49)
    canvas.removeEventListener('click',clickHandler);
}
canvas.addEventListener('click',clickHandler);

You can select multiple fields using linq Select as shown above in various examples this will return as an Anonymous Type. If you want to avoid this anonymous type here is the simple trick.

var items = listObject.Select(f => new List<int>() { f.Item1, f.Item2 }).SelectMany(item => item).Distinct();

I think this solves your problem

1. If your array is declared as static or is global, all the elements in the array already have default default value 0.
2. Some compilers set array's the default to 0 in debug mode.
3. It is easy to set default to 0 : int array[10] = {0};
4. However, for other values, you have use memset() or loop;

example: int array[10]; memset(array,-1, 10 *sizeof(int));

If you look at the Key that's been created (e.g. SourceTest) there will be a string value calledEventMessageFile, which for me was set to %SystemRoot%\System32\EventCreate.exe.

Change this to c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\EventLogMessages.dll

Delete theCustomSource and TypesSupported values.

This should stop the "The description for Event ID...." message.

You could try using the -Clear parameter

Example:-Clear Attribute1LDAPDisplayName, Attribute2LDAPDisplayName

http://technet.microsoft.com/en-us/library/ee617215.aspx

You could subtract the current time stamp from 12 AM of the same day.

Using current timestamp:

moment().valueOf() - moment().startOf('day').valueOf()

Using arbitrary day:

moment(someDate).valueOf() - moment(someDate).startOf('day').valueOf()

Take a surprise from gnu11!

typedef struct {
    uint8_t messType;
    uint8_t ax;  //axis
    uint32_t position;
    uint32_t velocity;
}TgotoData;

TgotoData tmpData = { 0 };

nothing is zero.

You can await on Promise.all():

await Promise.all([someCall(), anotherCall()]);

To store the results:

let [someResult, anotherResult] = await Promise.all([someCall(), anotherCall()]);

Note that Promise.all fails fast, which means that as soon as one of the promises supplied to it rejects, then the entire thing rejects.

const happy = (v, ms) => new Promise((resolve) => setTimeout(() => resolve(v), ms))
const sad = (v, ms) => new Promise((_, reject) => setTimeout(() => reject(v), ms))

Promise.all([happy('happy', 100), sad('sad', 50)])
  .then(console.log).catch(console.log) // 'sad'

If, instead, you want to wait for all the promises to either fulfill or reject, then you can use Promise.allSettled. Note that Internet Explorer does not natively support this method.

const happy = (v, ms) => new Promise((resolve) => setTimeout(() => resolve(v), ms))
const sad = (v, ms) => new Promise((_, reject) => setTimeout(() => reject(v), ms))

Promise.allSettled([happy('happy', 100), sad('sad', 50)])
  .then(console.log) // [{ "status":"fulfilled", "value":"happy" }, { "status":"rejected", "reason":"sad" }]

Note: If you use Promise.all actions that managed to finish before rejection happen are not rolled back, so you may need to take care of such situation. For example if you have 5 actions, 4 quick, 1 slow and slow rejects. Those 4 actions may be already executed so you may need to roll back. In such situation consider using Promise.allSettled while it will provide exact detail which action failed and which not.

This is one of the new features of Java 8, part of JDK Enhancement Proposals 122:

Remove the permanent generation from the Hotspot JVM and thus the need to tune the size of the permanent generation.

The list of all the JEPs that will be included in Java 8 can be found on the JDK8 milestones page.

All these answers and there is STILL just one missing. When you create your auth credential in the Google API section of the dev console, make sure (especially if it is your first one) that you have clicked on the 'consent screen' option. If you don't have the 'title' and any other required field filled out the call will fail with this option.

You have to click and hold until the other icon shows up, then slide the mouse down to the icon.

use fest assert 2.0 whenever possible EDIT: assertj may have more assertions (a fork)

assertThat(x).contains("foo");

I'm using mysql-connector-java-8.0.13 and had the same problem. I created my database in the command line console and solved this problem by using @Dimitry Rud's solution on the command line:

SET GLOBAL time_zone = '-6:00';

I didn't need to restart anything, set the time and immediately run my code in eclipse, it connected with no problems.

The bug is supposed to be fixed in an older version, but I think I got this error because after I created the database in the console, I didn't set this. I'm not using workbench nor another app to manage this rather than the console.

Note that the link you provided does is not an HTML page, but rather a JSON document. The formatting is done by the browser.

You have to decide if:

1. You want to show the raw JSON (not an HTML page), as in your example
2. Show an HTML page with formatted JSON

If you want 1., just tell your application to render a response body with the JSON, set the MIME type (application/json), etc. In this case, formatting is dealt by the browser (and/or browser plugins)

If 2., it's a matter of rendering a simple minimal HTML page with the JSON where you can highlight it in several ways:

• server-side, depending on your stack. There are solutions for almost every language
• client-side with Javascript highlight libraries.

If you give more details about your stack, it's easier to provide examples or resources.

EDIT: For client side JS highlighting you can try higlight.js, for instance.

The column is ambiguous because it appears in both tables you would need to specify the where (or sort) field fully such as us_music.genre or de_music.genre but you'd usually specify two tables if you were then going to join them together in some fashion. The structure your dealing with is occasionally referred to as a partitioned table although it's usually done to separate the dataset into distinct files as well rather than to just split the dataset arbitrarily. If you're in charge of the database structure and there's no good reason to partition the data then I'd build one big table with an extra "origin" field that contains a country code but you're probably doing it for legitimate performance reason. Either use a union to join the tables you're interested in http://dev.mysql.com/doc/refman/5.0/en/union.html or by using the Merge database engine http://dev.mysql.com/doc/refman/5.1/en/merge-storage-engine.html.

If you already know the key, you can directly update the value at that key using m[key] = new_value

Here is a sample code that might help:

map<int, int> m;

for(int i=0; i<5; i++)
    m[i] = i;

for(auto it=m.begin(); it!=m.end(); it++)
    cout<<it->second<<" ";
//Output: 0 1 2 3 4

m[4] = 7;  //updating value at key 4 here

cout<<"\n"; //Change line

for(auto it=m.begin(); it!=m.end(); it++)
    cout<<it->second<<" ";
// Output: 0 1 2 3 7    

Here you go.

$('#timePicker').datetimepicker({
   // dateFormat: 'dd-mm-yy',
   format:'DD/MM/YYYY HH:mm:ss',
    minDate: getFormattedDate(new Date())
});

function getFormattedDate(date) {
    var day = date.getDate();
    var month = date.getMonth() + 1;
    var year = date.getFullYear().toString().slice(2);
    return day + '-' + month + '-' + year;
}

You need to pass datepicker() the date formatted correctly.

You can also just grab the WebViewClient

wvClient = new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
  if (url.startsWith("youtube:")) {
    String youtubeUrl = "http://www.youtube.com/watch?v="
    + url.Replace("youtube:", "");
  startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(youtubeUrl)));
}
return false;
}

Worked fine in my app.

Sorting in an ORDER BY is done by the first column, and then by each additional column in the specified statement.

For instance, consider the following data:

Column1    Column2
=======    =======
1          Smith
2          Jones
1          Anderson
3          Andrews

The query

SELECT Column1, Column2 FROM thedata ORDER BY Column1, Column2

would first sort by all of the values in Column1

and then sort the columns by Column2 to produce this:

Column1    Column2
=======    =======
1          Anderson
1          Smith
2          Jones
3          Andrews

In other words, the data is first sorted in Column1 order, and then each subset (Column1 rows that have 1 as their value) are sorted in order of the second column.

The difference between the two statements you posted is that the rows in the first one would be sorted first by prod_price (price order, from lowest to highest), and then by order of name (meaning that if two items have the same price, the one with the lower alpha value for name would be listed first), while the second would sort in name order only (meaning that prices would appear in order based on the prod_name without regard for price).

Based on what I've read, this is how it all works:

The general flow outlined in the question is correct. In step 2, User X is authenticated, and is also authorizing Site A's access to User X's information on Site B. In step 4, the site passes its Secret back to Site B, authenticating itself, as well as the Authorization Code, indicating what it's asking for (User X's access token).

Overall, OAuth 2 actually is a very simple security model, and encryption never comes directly into play. Instead, both the Secret and the Security Token are essentially passwords, and the whole thing is secured only by the security of the https connection.

OAuth 2 has no protection against replay attacks of the Security Token or the Secret. Instead, it relies entirely on Site B being responsible with these items and not letting them get out, and on them being sent over https while in transit (https will protect URL parameters).

The purpose of the Authorization Code step is simply convenience, and the Authorization Code is not especially sensitive on its own. It provides a common identifier for User X's access token for Site A when asking Site B for User X's access token. Just User X's user id on Site B would not have worked, because there could be many outstanding access tokens waiting to be handed out to different sites at the same time.

If you want to use the ISO8601DateFormatter() with a date from a Rails 4+ JSON feed (and don't need millis of course), you need to set a few options on the formatter for it to work right otherwise the the date(from: string) function will return nil. Here's what I'm using:

extension Date {
    init(dateString:String) {
        self = Date.iso8601Formatter.date(from: dateString)!
    }

    static let iso8601Formatter: ISO8601DateFormatter = {
        let formatter = ISO8601DateFormatter()
        formatter.formatOptions = [.withFullDate,
                                          .withTime,
                                          .withDashSeparatorInDate,
                                          .withColonSeparatorInTime]
        return formatter
    }()
}

Here's the result of using the options verses not in a playground screenshot:

long is equivalent to long int, just as short is equivalent to short int. A long int is a signed integral type that is at least 32 bits, while a long long or long long int is a signed integral type is at least 64 bits.

This doesn't necessarily mean that a long long is wider than a long. Many platforms / ABIs use the LP64 model - where long (and pointers) are 64 bits wide. Win64 uses the LLP64, where long is still 32 bits, and long long (and pointers) are 64 bits wide.

There's a good summary of 64-bit data models here.

long double doesn't guarantee much other than it will be at least as wide as a double.

Use

position:absolute; right: 0;

No need for float:right with absolute positioning

Also, make sure the parent element is set to position:relative;

There's this approach:

[getattr(obj, m) for m in dir(obj) if not m.startswith('__')]

When dealing with a class instance, perhaps it'd be better to return a list with the method references instead of just names¹. If that's your goal, as well as

1. Using no import
2. Excluding private methods (e.g. __init__) from the list

It may be of use. You might also want to assure it's callable(getattr(obj, m)), since dir returns all attributes within obj, not just methods.

In a nutshell, for a class like

class Ghost:
    def boo(self, who):
        return f'Who you gonna call? {who}'

We could check instance retrieval with

>>> g = Ghost()
>>> methods = [getattr(g, m) for m in dir(g) if not m.startswith('__')]
>>> print(methods)
[<bound method Ghost.boo of <__main__.Ghost object at ...>>]

So you can call it right away:

>>> for method in methods:
...     print(method('GHOSTBUSTERS'))
...
Who you gonna call? GHOSTBUSTERS

¹ An use case:

I used this for unit testing. Had a class where all methods performed variations of the same process - which led to lengthy tests, each only a tweak away from the others. DRY was a far away dream.

Thought I should have a single test for all methods, so I made the above iteration.

Although I realized I should instead refactor the code itself to be DRY-compliant anyway... this may still serve a random nitpicky soul in the future.

but watch out for this....

Long nullLong = null;

preparedStatement.setLong( nullLong );

-thows null pointer exception-

because the protype is

setLong( long )   

NOT

setLong( Long )

nice one to catch you out eh.

Just like others explained - your problem stemmed from using \, which is escape character in string literal/constant. OTOH, if you had that file path string from another source (read from file, console or returned by os function) - there wouldn't have been problem splitting on '\\' or r'\'.

And just like others suggested, if you want to use \ in program literal, you have to either duplicate it \\ or the whole literal has to be prefixed by r, like so r'lite\ral' or r"lite\ral" to avoid the parser converting that \ and r to CR (carriage return) character.

There is one more way though - just don't use backslash \ pathnames in your code! Since last century Windows recognizes and works fine with pathnames which use forward slash as directory separator /! Somehow not many people know that.. but it works:

>>> var = "d:/stuff/morestuff/furtherdown/THEFILE.txt"
>>> var.split('/')
['d:', 'stuff', 'morestuff', 'furtherdown', 'THEFILE.txt']

This by the way will make your code work on Unix, Windows and Mac... because all of them do use / as directory separator... even if you don't want to use the predefined constants of module os.

This has worked for me :

                                } else {
                                    output += currentLine;
                                }

I came across a similar situation after publishing a ClickOnce application, and one of my colleagues on a different domain reported that it fails to launch.

To find out what was going on, I added a try catch statement inside the MainWindow method as @BradleyDotNET mentioned in one comment on the original post, and then published again.

public MainWindow()
{
    try
    {
        InitializeComponent();
    }
    catch (Exception exc)
    {
        MessageBox.Show(exc.ToString());
    }
}

Then my colleague reported to me the exception detail, and it was a missing reference of a third party framework dll file.

Added the reference and problem solved.

userType = (user.Type == 0) ? "Admin" : (user.type == 1) ? "User" : "Admin";

should do the trick.

iterate through the list. if the current value is larger than the stored largest value, store it as the largest value and bump the 1-4 down and 5 drops off the list. If not,compare it to number 2 and do the same thing. Repeat, checking it against all 5 stored values. this should do it in O(n)

Actual error

follow bellow two simple steps to fix.

Step 1:- update "Intel x86 Emulator Accelerator (HAXM installer)" Ref. bellow img

Step2:-

After installing the installer, you have to run it to install it on your system. Open the directory where your Android SDK is located. Go inside the extras\Intel\Hardware_Accelerated_Execution_Manager directory and you should see the intelhaxm-android.exe file.

If you got the error "This computer meets requirements for HAXM, but VT-x is not turned on..." during installation try to turn it on in your BIOS and check your antivirus software settings also. (Check this stackoverflow post). Thats it! its working for me.

Instead of writing

<hr>

Write

<hr class="col-xs-12">

And it will display full width as normal.

You can use mkdir:

#include <sys/types.h>

int result = mkdir("/home/me/test.txt", 0777);

@Paul Cavacas, I had the same issue and I solved by setting the Input() decorator above the getter.

  @Input('allowDays')
  get in(): any {
    return this._allowDays;
  }

  //@Input('allowDays')
  // not working
  set in(val) {
    console.log('allowDays = '+val);
    this._allowDays = val;
  }

As a workaround which achieves the same purpose, you may use the sprintf-js library and types.

I got it from another SO answer.

Python 3.4 introduced the pathlib module into the standard library, which provides an object oriented approach to handle filesystem paths. The is_dir() and exists() methods of a Path object can be used to answer the question:

In [1]: from pathlib import Path

In [2]: p = Path('/usr')

In [3]: p.exists()
Out[3]: True

In [4]: p.is_dir()
Out[4]: True

Paths (and strings) can be joined together with the / operator:

In [5]: q = p / 'bin' / 'vim'

In [6]: q
Out[6]: PosixPath('/usr/bin/vim') 

In [7]: q.exists()
Out[7]: True

In [8]: q.is_dir()
Out[8]: False

Pathlib is also available on Python 2.7 via the pathlib2 module on PyPi.

I had this issue when i cloned from a git repository and I had it resolved when I created a new project and re-inserted the src folder from the old project.

The src folder is the only folder needed when deploying your angular application but you must reconfigure the dev environment, using this solution.

a much more practical way for those who do not want to use regex:

$data = filter_var($data, FILTER_SANITIZE_NUMBER_INT);

note: it works with phone numbers too.

# reassign depth values under 10 to zero
df$depth[df$depth<10] <- 0

(For the columns that are factors, you can only assign values that are factor levels. If you wanted to assign a value that wasn't currently a factor level, you would need to create the additional level first:

levels(df$species) <- c(levels(df$species), "unknown") 
df$species[df$depth<10]  <- "unknown"

The type attribute is used to define the MIME type within the HTML document. Depending on what DOCTYPE you use, the type value is required in order to validate the HTML document.

The language attribute lets the browser know what language you are using (Javascript vs. VBScript) but is not necessarily essential and, IIRC, has been deprecated.

You want to replace it, not strip it:

s = s.replace(',', '')

All inputs should be replaced with custom directive that reads a single global variable to toggle readonly status.

It is whatever member of the enumeration represents the value 0. Specifically, from the documentation:

The default value of an enum E is the value produced by the expression (E)0.

As an example, take the following enum:

enum E
{
    Foo, Bar, Baz, Quux
}

Without overriding the default values, printing default(E) returns Foo since it's the first-occurring element.

However, it is not always the case that 0 of an enum is represented by the first member. For example, if you do this:

enum F
{
    // Give each element a custom value
    Foo = 1, Bar = 2, Baz = 3, Quux = 0
}

Printing default(F) will give you Quux, not Foo.

If none of the elements in an enum G correspond to 0:

enum G
{
    Foo = 1, Bar = 2, Baz = 3, Quux = 4
}

default(G) returns literally 0, although its type remains as G (as quoted by the docs above, a cast to the given enum type).

(Python3) This is what worked for me. If you just use the \010 then it will leave characters, so I tweaked it a bit to make sure it's overwriting what was there. This also allows you to have something before the first print item and only removed the length of the item.

print("Here are some strings: ", end="")
items = ["abcd", "abcdef", "defqrs", "lmnop", "xyz"]
for item in items:
    print(item, end="")
    for i in range(len(item)): # only moving back the length of the item
        print("\010 \010", end="") # the trick!
        time.sleep(0.2) # so you can see what it's doing

In a few words: The constructor is called first, then any @FXML annotated fields are populated, then initialize() is called.

This means the constructor does not have access to @FXML fields referring to components defined in the .fxml file, while initialize() does have access to them.

Quoting from the Introduction to FXML:

[...] the controller can define an initialize() method, which will be called once on an implementing controller when the contents of its associated document have been completely loaded [...] This allows the implementing class to perform any necessary post-processing on the content.

The for-in loops for each property in an object or array. You can use this property to get to the value as well as change it.

Note: Private properties are not available for inspection, unless you use a "spy"; basically, you override the object and write some code which does a for-in loop inside the object's context.

For in looks like:

for (var property in object) loop();

Some sample code:

function xinspect(o,i){
    if(typeof i=='undefined')i='';
    if(i.length>50)return '[MAX ITERATIONS]';
    var r=[];
    for(var p in o){
        var t=typeof o[p];
        r.push(i+'"'+p+'" ('+t+') => '+(t=='object' ? 'object:'+xinspect(o[p],i+'  ') : o[p]+''));
    }
    return r.join(i+'\n');
}

// example of use:
alert(xinspect(document));

Edit: Some time ago, I wrote my own inspector, if you're interested, I'm happy to share.

Edit 2: Well, I wrote one up anyway.

I assume you have your JS file declared inside the <head> tag so it keeps it consistent, like standard, then in your JS make sure the canvas initialization is after the page is loaded:

window.onload = function () {
    var myCanvas = document.getElementById('canvas');
    var ctx = myCanvas.getContext('2d');
}

There is no need to use jQuery just to initialize a canvas, it's very evident most of the programmers all around the world use it unnecessarily and the accepted answer is a probe of that.

1. Performance:

Assume your where clause is like this:

WHERE NAME='JON'

If the NAME column is of any type other than nvarchar or nchar, then you should not specify the N prefix. However, if the NAME column is of type nvarchar or nchar, then if you do not specify the N prefix, then 'JON' is treated as non-unicode. This means the data type of NAME column and string 'JON' are different and so SQL Server implicitly converts one operand’s type to the other. If the SQL Server converts the literal’s type to the column’s type then there is no issue, but if it does the other way then performance will get hurt because the column's index (if available) wont be used.

2. Character set:

If the column is of type nvarchar or nchar, then always use the prefix N while specifying the character string in the WHERE criteria/UPDATE/INSERT clause. If you do not do this and one of the characters in your string is unicode (like international characters - example - a) then it will fail or suffer data corruption.

For me, it only worked when I added the following line of code

$('#target').val($('#target').find("option:first").val());

params also allows you to call the method with a single argument.

private static int Foo(params int[] args) {
    int retVal = 0;
    Array.ForEach(args, (i) => retVal += i);
    return retVal;
}

i.e. Foo(1); instead of Foo(new int[] { 1 });. Can be useful for shorthand in scenarios where you might need to pass in a single value rather than an entire array. It still is handled the same way in the method, but gives some candy for calling this way.

I ran into a lot of issues when trying to figure this out. Here is my setup,

Dev Env : Windows 10, Java : 1.8.0_25, Spring Boot : 2.0.3.RELEASE, Spring : 5.0.7.RELEASE

What I found is spring is sticking with the concept "Sensible defaults for configuration". What this translates in to is, you have to have all your property files as part of your war file. Once in there, you can then override them using the "--spring.config.additional-location" command line property to point to external property files. But this will NOT WORK if the property files are not part of the original war file.

Demo code: https://github.com/gselvara/spring-boot-property-demo/tree/master

The following will parse an XML string into an XML document in all major browsers, including Internet Explorer 6. Once you have that, you can use the usual DOM traversal methods/properties such as childNodes and getElementsByTagName() to get the nodes you want.

var parseXml;
if (typeof window.DOMParser != "undefined") {
    parseXml = function(xmlStr) {
        return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
    };
} else if (typeof window.ActiveXObject != "undefined" &&
       new window.ActiveXObject("Microsoft.XMLDOM")) {
    parseXml = function(xmlStr) {
        var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
        xmlDoc.async = "false";
        xmlDoc.loadXML(xmlStr);
        return xmlDoc;
    };
} else {
    throw new Error("No XML parser found");
}

Example usage:

var xml = parseXml("<foo>Stuff</foo>");
alert(xml.documentElement.nodeName);

Which I got from https://stackoverflow.com/a/8412989/1232175.

Try this style instead, it modifies the template itself. In there you can change everything you need to transparent:

<Style TargetType="{x:Type TabItem}">
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type TabItem}">
        <Grid>
          <Border Name="Border" Margin="0,0,0,0" Background="Transparent"
                  BorderBrush="Black" BorderThickness="1,1,1,1" CornerRadius="5">
            <ContentPresenter x:Name="ContentSite" VerticalAlignment="Center"
                              HorizontalAlignment="Center"
                              ContentSource="Header" Margin="12,2,12,2"
                              RecognizesAccessKey="True">
              <ContentPresenter.LayoutTransform>
            <RotateTransform Angle="270" />
          </ContentPresenter.LayoutTransform>
        </ContentPresenter>
          </Border>
        </Grid>
        <ControlTemplate.Triggers>
          <Trigger Property="IsSelected" Value="True">

            <Setter Property="Foreground" Value="DarkGray" />
          </Trigger>
        </ControlTemplate.Triggers>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

Type casting to integer may create problem but even long type can not hold every bit of double after narrowing down to decimal places. If you know your values will never exceed Long.MAX_VALUE value, this might be a clean solution.

So use the following with the above known risk.

double mValue = 1234567890.123456;
long mStrippedValue = new Double(mValue).longValue();

Based on the syntax I'm assuming that it is some language which is descendant of C. As per what I have seen, length is used for simple collection items like arrays and in most cases it is a property.

size() is a function and is used for dynamic collection objects. However for all the purposes of using, you wont find any differences in outcome using either of them. In most implementations, size simply returns length property.

Do you have ROWS of data (horizontal) as you stated or COLUMNS (vertical)?

If it's the latter you can use "Text to columns" functionality to convert a whole column "in situ" - to do that:

Select column > Data > Text to columns > Next > Next > Choose "Date" under "column data format" and "YMD" from dropdown > Finish

....otherwise you can convert with a formula by using

=TEXT(A1,"0000-00-00")+0

and format in required date format

I think this will work even though this was forever ago.

SELECT employee_number, Row_Number()  
   OVER (PARTITION BY course_code ORDER BY course_completion_date DESC ) as rownum
FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
   AND rownum = 1

If you want to get the last Id if the date is the same then you can use this assuming your primary key is Id.

SELECT employee_number, Row_Number()  
   OVER (PARTITION BY course_code ORDER BY course_completion_date DESC, Id Desc) as rownum    FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
   AND rownum = 1

Since it's an array before you cast it, casting it makes no sense.

You may want a recursive cast, which would look something like this:

function arrayCastRecursive($array)
{
    if (is_array($array)) {
        foreach ($array as $key => $value) {
            if (is_array($value)) {
                $array[$key] = arrayCastRecursive($value);
            }
            if ($value instanceof stdClass) {
                $array[$key] = arrayCastRecursive((array)$value);
            }
        }
    }
    if ($array instanceof stdClass) {
        return arrayCastRecursive((array)$array);
    }
    return $array;
}

Usage:

$obj = new stdClass;
$obj->aaa = 'asdf';
$obj->bbb = 'adsf43';
$arr = array('asdf', array($obj, 3));

var_dump($arr);
$arr = arrayCastRecursive($arr);
var_dump($arr);

Result before:

array
    0 => string 'asdf' (length = 4)
  1 => 
    array
        0 =>
        object(stdClass)[1]
          public 'aaa' => string 'asdf' (length = 4)
          public 'bbb' => string 'adsf43' (length = 6)
      1 => int 3

Result after:

array
    0 => string 'asdf' (length = 4)
  1 => 
    array
        0 =>
        array
          'aaa' => string 'asdf' (length = 4)
          'bbb' => string 'adsf43' (length = 6)
      1 => int 3

Note:

Tested and working with complex arrays where a stdClass object can contain other stdClass objects.

Actually this seems to be the correct way:

$('form').submit(function(e){

    //prevent default
    e.preventDefault();

    //do something here

    //continue submitting
    e.currentTarget.submit();

});

I had to add both manager-gui and manager-script roles for it to work, in version 9.

After getting the access to MangerApp, while trying to upload .war file, I got the exception

org.apache.tomcat.util.http.fileupload.FileUploadBase$IOFileUploadException

which I was able to solve using the answer of this post

To get access for Host Manager, check this post

I think I figured it out: computes number of seconds since epoch, then converts to a local timzeone using time.localtime, and then converts the time struct back into a datetime...

EPOCH_DATETIME = datetime.datetime(1970,1,1)
SECONDS_PER_DAY = 24*60*60

def utc_to_local_datetime( utc_datetime ):
    delta = utc_datetime - EPOCH_DATETIME
    utc_epoch = SECONDS_PER_DAY * delta.days + delta.seconds
    time_struct = time.localtime( utc_epoch )
    dt_args = time_struct[:6] + (delta.microseconds,)
    return datetime.datetime( *dt_args )

It applies the summer/winter DST correctly:

>>> utc_to_local_datetime( datetime.datetime(2010, 6, 6, 17, 29, 7, 730000) )
datetime.datetime(2010, 6, 6, 19, 29, 7, 730000)
>>> utc_to_local_datetime( datetime.datetime(2010, 12, 6, 17, 29, 7, 730000) )
datetime.datetime(2010, 12, 6, 18, 29, 7, 730000)

NOTE: The below solution no longer works on iOS 13+ devices - it will return garbage data.

Please use following code instead:

+ (NSString *)hexadecimalStringFromData:(NSData *)data
{
  NSUInteger dataLength = data.length;
  if (dataLength == 0) {
    return nil;
  }

  const unsigned char *dataBuffer = (const unsigned char *)data.bytes;
  NSMutableString *hexString  = [NSMutableString stringWithCapacity:(dataLength * 2)];
  for (int i = 0; i < dataLength; ++i) {
    [hexString appendFormat:@"%02x", dataBuffer[i]];
  }
  return [hexString copy];
}

Solution that worked prior to iOS 13:

Objective-C

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken 
{
    NSString *token = [[deviceToken description] stringByTrimmingCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
    NSLog(@"this will return '32 bytes' in iOS 13+ rather than the token", token);
} 

Swift 3.0

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
{
    let tokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
    print("this will return '32 bytes' in iOS 13+ rather than the token \(tokenString)")
}

Use this for GET values:

Request.QueryString["key"]

And this for POST values

Request.Form["key"]

Also, this will work if you don't care whether it comes from GET or POST, or the HttpContext.Items collection:

Request["key"]

Another thing to note (if you need it) is you can check the type of request by using:

Request.RequestType

Which will be the verb used to access the page (usually GET or POST). Request.IsPostBack will usually work to check this, but only if the POST request includes the hidden fields added to the page by the ASP.NET framework.

I am in ubuntu 14.04 and mongod is registered as an upstart service. The answers in this post sent me in the right direction. The only adaptation I had to do to make things work with the upstart service was to edit /etc/mongod.conf. Look for the lines that read:

# Enable the HTTP interface (Defaults to port 28017).
# httpinterface = true

Just remove the # in front of httpinterface and restart the mongod service:

sudo restart mongod

Note: You can also enable the rest interface by adding a line that reads rest=true right below the httpinterface line mentioned above.

This was pretty well answered over here: How to make a YouTube embedded video a full page width one?

If you add '?rel=0&autoplay=1' to the end of the url in the embed code (like this)

<iframe id="video" src="//www.youtube.com/embed/5iiPC-VGFLU?rel=0&autoplay=1" frameborder="0" allowfullscreen></iframe>

of the video it should play on load. Here's a demo over at jsfiddle.

I had a similar problem. I solved it using:

find dir_name '*.mp3' -exec cp -vuni '{}' "../dest_dir" ";"

The '{}' and ";" executes the copy on each file.

Try this scenario:

Array = A1:C7. A1-A3 have values, B2-B6 have value and C1, C3 and C6 have values.

To get a count of the number of rows add a column D (you can hide it after formulas are set up) and in D1 put formula =If(Sum(A1:C1)>0,1,0). Copy the formula from D1 through D7 (for others searching who are not excel literate, the numbers in the sum formula will change to the row you are on and this is fine).

Now in C8 make a sum formula that adds up the D column and the answer should be 6. For visually pleasing purposes hide column D.

Here's another alternative. This one was originally written in C++, so it can be backported to C++ for a finite-precision integer (e.g. __int64). The advantage is (1) it involves only integer operations, and (2) it avoids bloating the integer value by doing successive pairs of multiplication and division. I've tested the result with Nas Banov's Pascal triangle, it gets the correct answer:

def choose(n,r):
  """Computes n! / (r! (n-r)!) exactly. Returns a python long int."""
  assert n >= 0
  assert 0 <= r <= n

  c = 1L
  denom = 1
  for (num,denom) in zip(xrange(n,n-r,-1), xrange(1,r+1,1)):
    c = (c * num) // denom
  return c

Rationale: To minimize the # of multiplications and divisions, we rewrite the expression as

    n!      n(n-1)...(n-r+1)
--------- = ----------------
 r!(n-r)!          r!

To avoid multiplication overflow as much as possible, we will evaluate in the following STRICT order, from left to right:

n / 1 * (n-1) / 2 * (n-2) / 3 * ... * (n-r+1) / r

We can show that integer arithmatic operated in this order is exact (i.e. no roundoff error).

@DSM's answer is perfectly fine in almost any normal scenario. But if you're the type of programmer who wants to go a little deeper than the surface level, you might be interested to know that it is a little faster to call numpy functions on the underlying .to_numpy() (or .values for <0.24) array instead of directly calling the (cythonized) functions defined on the DataFrame/Series objects.

For example, you can use ndarray.max() along the first axis.

# Data borrowed from @DSM's post.
df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
df
   A  B
0  1 -2
1  2  8
2  3  1

df['C'] = df[['A', 'B']].values.max(1)
# Or, assuming "A" and "B" are the only columns, 
# df['C'] = df.values.max(1) 
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3 

If your data has NaNs, you will need numpy.nanmax:

df['C'] = np.nanmax(df.values, axis=1)
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3 

You can also use numpy.maximum.reduce. numpy.maximum is a ufunc (Universal Function), and every ufunc has a reduce:

df['C'] = np.maximum.reduce(df['A', 'B']].values, axis=1)
# df['C'] = np.maximum.reduce(df[['A', 'B']], axis=1)
# df['C'] = np.maximum.reduce(df, axis=1)
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3

np.maximum.reduce and np.max appear to be more or less the same (for most normal sized DataFrames)—and happen to be a shade faster than DataFrame.max. I imagine this difference roughly remains constant, and is due to internal overhead (indexing alignment, handling NaNs, etc).

The graph was generated using perfplot. Benchmarking code, for reference:

import pandas as pd
import perfplot

np.random.seed(0)
df_ = pd.DataFrame(np.random.randn(5, 1000))

perfplot.show(
    setup=lambda n: pd.concat([df_] * n, ignore_index=True),
    kernels=[
        lambda df: df.assign(new=df.max(axis=1)),
        lambda df: df.assign(new=df.values.max(1)),
        lambda df: df.assign(new=np.nanmax(df.values, axis=1)),
        lambda df: df.assign(new=np.maximum.reduce(df.values, axis=1)),
    ],
    labels=['df.max', 'np.max', 'np.maximum.reduce', 'np.nanmax'],
    n_range=[2**k for k in range(0, 15)],
    xlabel='N (* len(df))',
    logx=True,
    logy=True)

This is more of a rare issue but I have seen this if someone has copied the entire /var/lib/mysql directory as a way of migrating their DB to another server. The reason it doesn't work is because the database was running and using log files. It doesn't work sometimes if there are logs in /var/log/mysql. The solution is to copy the /var/log/mysql files as well.

Using the following imports:

import {Observable} from 'rxjs/Observable';
import 'rxjs/add/observable/of';
import 'rxjs/add/operator/delay';

Try this:

let fakeResponse = [1,2,3];
let delayedObservable = Observable.of(fakeResponse).delay(5000);
delayedObservable.subscribe(data => console.log(data));

UPDATE: RXJS 6

The above solution doesn't really work anymore in newer versions of RXJS (and of angular for example).

So the scenario is that I have an array of items to check with an API with. The API only accepts a single item, and I do not want to kill the API by sending all requests at once. So I need a timed release of items on the Observable stream with a small delay in between.

Use the following imports:

import { from, of } from 'rxjs';
import { delay } from 'rxjs/internal/operators';
import { concatMap } from 'rxjs/internal/operators';

Then use the following code:

const myArray = [1,2,3,4];

from(myArray).pipe(
        concatMap( item => of(item).pipe ( delay( 1000 ) ))
    ).subscribe ( timedItem => {
        console.log(timedItem)
    });

It basically creates a new 'delayed' Observable for every item in your array. There are probably many other ways of doing it, but this worked fine for me, and complies with the 'new' RXJS format.

As AraK said, the c++ streams interface will always work portably.

std::size_t s = 1024; std::cout << s; // or any other kind of stream like stringstream!

If you want C stdio, there is no portable answer to this for certain cases of "portable." And it gets ugly since as you've seen, picking the wrong format flags may yield a compiler warning or give incorrect output.

C99 tried to solve this problem with inttypes.h formats like "%"PRIdMAX"\n". But just as with "%zu", not everyone supports c99 (like MSVS prior to 2013). There are "msinttypes.h" files floating around to deal with this.

If you cast to a different type, depending on flags you may get a compiler warning for truncation or a change of sign. If you go this route pick a larger relevant fixed size type. One of unsigned long long and "%llu" or unsigned long "%lu" should work, but llu may also slow things down in a 32bit world as excessively large. (Edit - my mac issues a warning in 64 bit for %llu not matching size_t, even though %lu, %llu, and size_t are all the same size. And %lu and %llu are not the same size on my MSVS2012. So you may need to cast + use a format that matches.)

For that matter, you can go with fixed size types, such as int64_t. But wait! Now we're back to c99/c++11, and older MSVS fails again. Plus you also have casts (e.g. map.size() is not a fixed size type)!

You can use a 3rd party header or library such as boost. If you're not already using one, you may not want to inflate your project that way. If you're willing to add one just for this issue, why not use c++ streams, or conditional compilation?

So you're down to c++ streams, conditional compilation, 3rd party frameworks, or something sort of portable that happens to work for you.

On macOS, use subprocess.run to pipe your text to pbcopy:

import subprocess 
data = "hello world"
subprocess.run("pbcopy", universal_newlines=True, input=data)

It will copy "hello world" to the clipboard.

You could always use mysql's LOAD DATA:

LOAD DATA LOCAL INFILE '/full/path/to/file/foo.csv' INTO TABLE `footable` FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n' 

to do bulk inserts rather than using a bunch of INSERT statements.

Assuming you are using VSTS run vsts-npm-auth -config .npmrc to generate new .npmrc file with the auth token

You need to use the command pscp and forcing it to pass through sftp protocol. pscp is automatically installed when you install PuttY, a software to connect to a linux server through ssh.

When you have your pscp command here is the command line:

pscp -sftp -pw <yourPassword> "<pathToYourFile(s)>" <username>@<serverIP>:<PathInTheServerFromTheHomeDirectory>

These parameters (-sftp and -pw) are only available with pscp and not scp. You can also add -r if you want to upload everything in a folder in a recursive way.

$keys = array_keys($arr);
$keys = rsort($keys);

print $keys[0];

should print "10"

string[] lines = Regex.Split(value, ".{5}");  
string out = "";
foreach (string line in lines)  
{  
    out += "-" + line;
}
out = out.Substring(1);

you must do 4 following step :

1. create event

   var event = new Event("change",{
       detail: {
           oldValue:yourValueVariable,
           newValue:!yourValueVariable
       },
       bubbles: true,
       cancelable: true
   });
   event.simulated = true;
   let tracker = this.yourComponentDomRef._valueTracker;
   if (tracker) {
       tracker.setValue(!yourValueVariable);
   }
   

2. bind value to component dom

   this.yourComponentDomRef.value = !yourValueVariable;
   

3. bind element onchange to react onChange function

    this.yourComponentDomRef.onchange = (e)=>this.props.onChange(e);
   

4. dispatch event

   this.yourComponentDomRef.dispatchEvent(event);
   

in above code yourComponentDomRef refer to master dom of your React component for example <div className="component-root-dom" ref={(dom)=>{this.yourComponentDomRef= dom}}>

we can use different types of system fonts like below

myButton.titleLabel?.font = UIFont.boldSystemFont(ofSize: 17)
myButton.titleLabel?.font = UIFont.italicSystemFont(ofSize:UIFont.smallSystemFontSize)
myButton.titleLabel?.font = UIFont.boldSystemFont(ofSize: UIFont.buttonFontSize)

and your custom font like below

    myButton.titleLabel?.font = UIFont(name: "Helvetica", size:12)

Try to edit your my.cf and comment the original sql_mode and add sql_mode = "".

vi /etc/mysql/my.cnf

sql_mode = ""

save and quit...

I know its late to answer here, still if anybody want to know solution is below

conversationView.smoothScrollToPosition(conversationView.getAdapter().getItemCount() - 1);

From the API (http://msdn.microsoft.com/en-us/library/system.datetime_members(VS.71).aspx) it does not seem it can show the name of the time zone used.

I would love to add that you can even use arrows /text boxes to annotate the labels. Here is what I mean:

Which will generate the following graph:

git checkout -b your-new-branch

git add <files>

git commit -m <message>

First, checkout your new branch. Then add all the files you want to commit to staging. Lastly, commit all the files you just added. You might want to do a git push origin your-new-branch afterward so your changes show up on the remote.

Another version of the function without error handling. This time it is not case sensitive and a little bit more efficient.

Function WorksheetExists(wsName As String) As Boolean
    Dim ws As Worksheet
    Dim ret As Boolean        
    wsName = UCase(wsName)
    For Each ws In ThisWorkbook.Sheets
        If UCase(ws.Name) = wsName Then
            ret = True
            Exit For
        End If
    Next
    WorksheetExists = ret
End Function

Very weird experience I have encountered!

I had cloned with GIT bash and GIT cmd-Line earlier, I encountered the above issues.

Later, I cloned with Tortoise-GIT and everything worked as expected.

May be this is a crazy answer, but trying with this once may save your time!

My opinion is that selectedIndex or using objectAtIndex is not necessarily the best way to switch the tab. If you reorder your tabs, a hard coded index selection might mess with your former app behavior.

If you have the object reference of the view controller you want to switch to, you can do:

tabBarController.selectedViewController = myViewController

Of course you must make sure, that myViewController really is in the list of tabBarController.viewControllers.

You should read-up on jQueryUI Datepicker

Once you include the relevant jQuery UI library, it's as simple as,

Script:

$(function() {
    $( "#datepicker" ).datepicker();
});

HTML:

<input type="text" id="datepicker" />

Pros:

• it is thoroughly tested for x-browser compatibility, so you won't have a problem.
• Separate css file, so you can customize it as per your liking

You can use Wget or cURL, see How to download files from command line in Windows like wget or curl.

You will then do e.g.:

wget www.google.com

A multi dimensional sorting method, based on this answer:

Update: Here is an "optimized" version. It does a lot more preprocessing and creates a comparison function for each sorting option beforehand. It might need more more memory (as it stores a function for each sorting option, but it should preform a bit better as it does not have to determine the correct settings during the comparison. I have not done any profiling though.

var sort_by;

(function() {
    // utility functions
    var default_cmp = function(a, b) {
            if (a == b) return 0;
            return a < b ? -1 : 1;
        },
        getCmpFunc = function(primer, reverse) {
            var dfc = default_cmp, // closer in scope
                cmp = default_cmp;
            if (primer) {
                cmp = function(a, b) {
                    return dfc(primer(a), primer(b));
                };
            }
            if (reverse) {
                return function(a, b) {
                    return -1 * cmp(a, b);
                };
            }
            return cmp;
        };

    // actual implementation
    sort_by = function() {
        var fields = [],
            n_fields = arguments.length,
            field, name, reverse, cmp;

        // preprocess sorting options
        for (var i = 0; i < n_fields; i++) {
            field = arguments[i];
            if (typeof field === 'string') {
                name = field;
                cmp = default_cmp;
            }
            else {
                name = field.name;
                cmp = getCmpFunc(field.primer, field.reverse);
            }
            fields.push({
                name: name,
                cmp: cmp
            });
        }

        // final comparison function
        return function(A, B) {
            var a, b, name, result;
            for (var i = 0; i < n_fields; i++) {
                result = 0;
                field = fields[i];
                name = field.name;

                result = field.cmp(A[name], B[name]);
                if (result !== 0) break;
            }
            return result;
        }
    }
}());

Example usage:

homes.sort(sort_by('city', {name:'price', primer: parseInt, reverse: true}));

DEMO

Original function:

var sort_by = function() {
   var fields = [].slice.call(arguments),
       n_fields = fields.length;

   return function(A,B) {
       var a, b, field, key, primer, reverse, result, i;

       for(i = 0; i < n_fields; i++) {
           result = 0;
           field = fields[i];

           key = typeof field === 'string' ? field : field.name;

           a = A[key];
           b = B[key];

           if (typeof field.primer  !== 'undefined'){
               a = field.primer(a);
               b = field.primer(b);
           }

           reverse = (field.reverse) ? -1 : 1;

           if (a<b) result = reverse * -1;
           if (a>b) result = reverse * 1;
           if(result !== 0) break;
       }
       return result;

<context:property-placeholder ... /> is the XML equivalent to the PropertyPlaceholderConfigurer. So, prefer that. The <util:properties/> simply factories a java.util.Properties instance that you can inject.

In Spring 3.1 (not 3.0...) you can do something like this:

@Configuration
@PropertySource("/foo/bar/services.properties")
public class ServiceConfiguration { 

    @Autowired Environment environment; 

    @Bean public javax.sql.DataSource dataSource( ){ 
        String user = this.environment.getProperty("ds.user");
        ...
    } 
}

In Spring 3.0, you can "access" properties defined using the PropertyPlaceHolderConfigurer mechanism using the SpEl annotations:

@Value("${ds.user}") private String user;

If you want to remove the XML all together, simply register the PropertyPlaceholderConfigurer manually using Java configuration. I prefer the 3.1 approach. But, if youre using the Spring 3.0 approach (since 3.1's not GA yet...), you can now define the above XML like this:

@Configuration 
public class MySpring3Configuration {     
        @Bean 
        public static PropertyPlaceholderConfigurer configurer() { 
             PropertyPlaceholderConfigurer ppc = ...
             ppc.setLocations(...);
             return ppc; 
        } 

        @Bean 
        public class DataSource dataSource(
                @Value("${ds.user}") String user, 
                @Value("${ds.pw}") String pw, 
                ...) { 
            DataSource ds = ...
            ds.setUser(user);
            ds.setPassword(pw);                        
            ...
            return ds;
        }
}

Note that the PPC is defined using a static bean definition method. This is required to make sure the bean is registered early, because the PPC is a BeanFactoryPostProcessor - it can influence the registration of the beans themselves in the context, so it necessarily has to be registered before everything else.

Try gzipping some data through the gzip libary like this...

import gzip
content = "Lots of content here"
f = gzip.open('Onlyfinnaly.log.gz', 'wb')
f.write(content)
f.close()

... then run your code as posted ...

import gzip
f=gzip.open('Onlyfinnaly.log.gz','rb')
file_content=f.read()
print file_content

This method worked for me as for some reason the gzip library fails to read some files.

If your images are named you can reference them through the DOM and change the source.

document["imgName"].src="../newImgSrc.jpg";

or

document.getElementById("imgName").src="../newImgSrc.jpg";

A good old regex seems to be faster than the most of the previous shown methods:

// both of the below calls will output: ShortClassName

echo preg_replace('/.*\\\\/', '', 'ShortClassName');
echo preg_replace('/.*\\\\/', '', 'SomeNamespace\SomePath\ShortClassName');

So this works even when you provide a short class name or a fully qualified (canonical) class name.

What the regex does is that it consumes all previous chars until the last separator is found (which is also consumed). So the remaining string will be the short class name.

If you want to use a different separator (eg. / ) then just use that separator instead. Remember to escape the backslash (ie. \) and also the pattern char (ie. /) in the input pattern.

With Java 8 lambda expression you can do something like

cats.stream()
    .filter( c -> c.getAge() == 3 && c.getFavoriteFood() == WHISKAS )
    .collect(Collectors.toList());

Conceptually the same as the Guava Predicate approach, but it looks much cleaner with lambda

Probably not a valid answer for OP but worth to note for people with similar need. :)

This is actually pretty easy in Excel (or any spreadsheet application).

You'll want to use the =CONCATENATE() function as shown in the formula bar in the following screenshot:

Step 1 involves adding quotes in column B,

Step 2 involves specifying the function and then copying it down column C (by now your spreadsheet should look like the screenshot),

Step 3 (if you need the text outside of the formula) involves copying column C, right-clicking on column D, choosing Paste Special >> Paste Values. Column D should then contain the text that was calculated in column C.

Both UNION and UNION ALL concatenate the result of two different SQLs. They differ in the way they handle duplicates.

• UNION performs a DISTINCT on the result set, eliminating any duplicate rows.

• UNION ALL does not remove duplicates, and it therefore faster than UNION.

Note: While using this commands all selected columns need to be of the same data type.

Example: If we have two tables, 1) Employee and 2) Customer

1. Employee table data:

2. Customer table data:

3. UNION Example (It removes all duplicate records):

4. UNION ALL Example (It just concatenate records, not eliminate duplicates, so it is faster than UNION):

I experienced this issue and couldn't figure out a fix for a few hours, until I realised I had incorrectly prevented native events from occurring with:

<input type="checkbox" @click.prevent="toggleConfirmedStatus(render.uuid)"
    :checked="confirmed.indexOf(render.uuid) > -1"
    :value="render.uuid"
/>

removing the .prevent from the @click handler fixed my issue.

I prefer to use converting to sets and then using the "difference()" function. The full code is :

temp1 = ['One', 'Two', 'Three', 'Four'  ]                   
temp2 = ['One', 'Two']
set1 = set(temp1)
set2 = set(temp2)
set3 = set1.difference(set2)
temp3 = list(set3)
print(temp3)

Output:

>>>print(temp3)
['Three', 'Four']

It's the easiest to undersand, and morover in future if you work with large data, converting it to sets will remove duplicates if duplicates are not required. Hope it helps ;-)

Depending on your case, you could prefer to use a hash of methods.

If there is a long list of whens and each of them has a concrete value to compare with (not an interval), it will be more effective to declare a hash of methods and then to call the relevant method from the hash like that.

# Define the hash
menu = {a: :menu1, b: :menu2, c: :menu2, d: :menu3}

# Define the methods
def menu1
  puts 'menu 1'
end

def menu2
  puts 'menu 2'
end

def menu3
  puts 'menu3'
end

# Let's say we case by selected_menu = :a
selected_menu = :a

# Then just call the relevant method from the hash
send(menu[selected_menu])

The semantically correct character is the Interpunct, also known as middle dot, as HTML entity

·

Example

Home · Photos · About

You could also use the bullet point character, as HTML entity

•

Example

Home • Photos • About

It shouldn't be HTTP headers if the file has been downloaded successfully and it's the same file that you can open from OI.

A shot in the dark, but could it be that you are not allowing installation from unknown sources, and that OI is somehow bypassing that?

Answer extracted from comments which worked. Ensure the Content-Type is set to application/vnd.android.package-archive

Would sending the mail as plain-text sort this?

"How to Send a Plain Text Message in Outlook":

• Select Actions | New Mail Message Using | Plain Text from the menu in Outlook.
• Create your message as usual.
• Click Send to deliver it.

Being plain text it shouldn't screw up your code, with "smart" quotes, auto-capitalisation and such.

Another possible option, if this is a common problem within the company perhaps you could setup an internal code-paste site, there's plenty of open-source ones around, like Open Pastebin

I found that contentSize doesn't really reflect the actual size of the text, so when trying to scroll to the bottom, it will be a little bit off. The best way to determine the actual content size is actually to use the NSLayoutManager's usedRectForTextContainer: method:

UITextView *textView;
CGSize textSize = [textView.layoutManager usedRectForTextContainer:textView.textContainer].size;

To determine how much text actually is shown in the UITextView, you can calculate it by subtracting the text container insets from the frame height.

UITextView *textView;
UIEdgeInsets textInsets = textView.textContainerInset;
CGFloat textViewHeight = textView.frame.size.height - textInsets.top - textInsets.bottom;

Then it becomes easy to scroll:

// if you want scroll animation, use contentOffset
UITextView *textView;
textView.contentOffset = CGPointMake(textView.contentOffset.x, textSize - textViewHeight);

// if you don't want scroll animation
CGRect scrollBounds = textView.bounds;
scrollBounds.origin = CGPointMake(textView.contentOffset.x, textSize - textViewHeight);
textView.bounds = scrollBounds;

Some numbers for reference on what the different sizes represent for an empty UITextView.

textView.frame.size = (width=246, height=50)
textSize = (width=10, height=16.701999999999998)
textView.contentSize = (width=246, height=33)
textView.textContainerInset = (top=8, left=0, bottom=8, right=0)

IDs must be unique in your document, meaning that you shouldn't do this:

<input type="checkbox" name="chk[]" id="chk[]" value="Apples" />
<input type="checkbox" name="chk[]" id="chk[]" value="Bananas" />

Instead, drop the ID, and then select them by name, or by a containing element:

<fieldset id="checkArray">
    <input type="checkbox" name="chk[]" value="Apples" />

    <input type="checkbox" name="chk[]" value="Bananas" />
</fieldset>

And now the jQuery:

var atLeastOneIsChecked = $('#checkArray:checkbox:checked').length > 0;
//there should be no space between identifier and selector

// or, without the container:

var atLeastOneIsChecked = $('input[name="chk[]"]:checked').length > 0;

Way1 :

@Entity

@Table(name = "table_name", uniqueConstraints={@UniqueConstraint(columnNames = "column1"),@UniqueConstraint(columnNames = "column2")})

-- Here both Column1 and Column2 acts as unique constraints separately. Ex : if any time either the value of column1 or column2 value matches then you will get UNIQUE_CONSTRAINT Error.

Way2 :

@Entity

@Table(name = "table_name", uniqueConstraints={@UniqueConstraint(columnNames ={"column1","column2"})})

-- Here both column1 and column2 combined values acts as unique constraints

Arrays are allocated memory at compile time in java, so they are static, the elements not explicitly set or modified are set with the default values. You could use some code like this, though it is not recommended as it does not count default values, even if you explicitly initialize them that way, it is also likely to cause bugs down the line. As others said, when looking for the actual size, ".length" must be used instead of ".length()".

public int logicalArrayLength(type[] passedArray) {
    int count = 0;
    for (int i = 0; i < passedArray.length; i++) {
        if (passedArray[i] != defaultValue) {
            count++;
        }
    }
    return count;
}

To match pattern or an empty string, use

^$|pattern

Explanation

• ^ and $ are the beginning and end of the string anchors respectively.
• | is used to denote alternates, e.g. this|that.

References

• regular-expressions.info/Anchors and Alternation

On \b

\b in most flavor is a "word boundary" anchor. It is a zero-width match, i.e. an empty string, but it only matches those strings at very specific places, namely at the boundaries of a word.

That is, \b is located:

• Between consecutive \w and \W (either order):

It's also possible through XmlSerialization.
The idea is - serialize to `XML` and then `readXml` method of `DataSet`.

I use this code (from an answer in SO, forgot where)

        public static string SerializeXml<T>(T value) where T : class
    {
        if (value == null)
        {
            return null;
        }

        XmlSerializer serializer = new XmlSerializer(typeof(T));

        XmlWriterSettings settings = new XmlWriterSettings();

        settings.Encoding = new UnicodeEncoding(false, false);
        settings.Indent = false;
        settings.OmitXmlDeclaration = false;
        // no BOM in a .NET string

        using (StringWriter textWriter = new StringWriter())
        {
            using (XmlWriter xmlWriter = XmlWriter.Create(textWriter, settings))
            {
               serializer.Serialize(xmlWriter, value);
            }
            return textWriter.ToString();
        }
    }

so then it's as simple as:

            string xmlString = Utility.SerializeXml(trans.InnerList);

        DataSet ds = new DataSet("New_DataSet");
        using (XmlReader reader = XmlReader.Create(new StringReader(xmlString)))
        { 
            ds.Locale = System.Threading.Thread.CurrentThread.CurrentCulture;
            ds.ReadXml(reader); 
        }

Not sure how it stands against all the other answers to this post, but it's also a possibility.

It's a big problem indeed. Try out this code:

print "%.2f" % (round((2*4.4+3*5.6+3*4.4)/8,2),)

It displays 4.85. Then you do:

print "Media = %.1f" % (round((2*4.4+3*5.6+3*4.4)/8,1),)

and it shows 4.8. Do you calculations by hand the exact answer is 4.85, but if you try:

print "Media = %.20f" % (round((2*4.4+3*5.6+3*4.4)/8,20),)

you can see the truth: the float point is stored as the nearest finite sum of fractions whose denominators are powers of two.

Multiply by 1000, round, and divide back by 1000.

For basic Java: http://download.oracle.com/javase/tutorial/getStarted/index.html and http://download.oracle.com/javase/tutorial/java/index.html

You can use sprintf: http://php.net/manual/en/function.sprintf.php

<?php
$num = 4;
$num_padded = sprintf("%02d", $num);
echo $num_padded; // returns 04
?>

It will only add the zero if it's less than the required number of characters.

Edit: As pointed out by @FelipeAls:

When working with numbers, you should use %d (rather than %s), especially when there is the potential for negative numbers. If you're only using positive numbers, either option works fine.

For example:

sprintf("%04s", 10); returns 0010
sprintf("%04s", -10); returns 0-10

Where as:

sprintf("%04d", 10); returns 0010
sprintf("%04d", -10); returns -010

This variant is better because you could not know whether file exists or not. You should send correct header when you know for certain that you can read contents of your file. Also, if you have branches of code that does not finish with '.end()', browser will wait until it get them. In other words, your browser will wait a long time.

var fs = require("fs");
var filename = "./index.html";

function start(resp) {

    fs.readFile(filename, "utf8", function(err, data) {
        if (err) {
            // may be filename does not exists?
            resp.writeHead(404, {
                'Content-Type' : 'text/html'
            });
            // log this error into browser
            resp.write(err.toString());
            resp.end();
        } else {

            resp.writeHead(200, {
                "Content-Type": "text/html"
            });      
            resp.write(data.toString());
            resp.end();
        }
    });
}

I had a huge problems with auto layout. We have two containers inside table cell. Second container is resized depending on Item description (0 - 1000 chars), and row should be resized based on them.

The missing ingredient was bottom constraint for description.

I've changed bottom constraint of dynamic element from = 0 to >= 0.

I had a similar issue, but with no source code to run on Xcode.

So if you want to test an application on a real device with a fake location you should use a VPN application.

There are plenty in the App Store to choose from - free ones without the option to choose a specific country/city and free ones which assign you a random location or asks you to choose from a limited set of default options.

I know this is old but this answer came up in search results. For the next guy - the proposed and accepted answer works, however the code initially submitted in the question is lower-level than it needs to be. Nobody got time for that.

//one-line post request/response...
response, err := http.PostForm(APIURL, url.Values{
    "ln": {c.ln},
    "ip": {c.ip},
    "ua": {c.ua}})

//okay, moving on...
if err != nil {
  //handle postform error
}

defer response.Body.Close()
body, err := ioutil.ReadAll(response.Body)

if err != nil {
  //handle read response error
}

fmt.Printf("%s\n", string(body))

The following code works for me on owl carousel .

https://github.com/OwlFonk/OwlCarousel

$(".owl-carousel").owlCarousel({
    items: 1,
    autoplay: true,
    navigation: true,
    navigationText: ["<i class='fa fa-angle-left'></i>", "<i class='fa fa-angle-right'></i>"]
});

For OwlCarousel2

https://owlcarousel2.github.io/OwlCarousel2/docs/api-options.html

 $(".owl-carousel").owlCarousel({
    items: 1,
    autoplay: true,
    nav: true,
    navText: ["<i class='fa fa-angle-left'></i>", "<i class='fa fa-angle-right'></i>"]
});

Steps to perform the task:

1. First, download and install the compiler.

2. Then, type the C/C++ program and save it.

3. Then, open the command line and change directory to the particular one where the source file is stored, using cd like so:

   cd C:\Documents and Settings\...
   

4. Then, to compile, type in the command prompt:

   gcc sourcefile_name.c -o outputfile.exe
   

5. Finally, to run the code, type:

   outputfile.exe
   

I think use drop duplicate sometimes will not so useful depending dataframe.

I found this:

[in] df['col_1'].unique()
[out] array(['A', 'B', 'C'], dtype=object)

And work for me!

As simple as:

your_map.begin()->first // key
your_map.begin()->second // value

As far as i know this issue appears only for the pathvariable at the end of the requestmapping.

We were able to solve that by defining the regex addon in the requestmapping.

 /somepath/{variable:.+}

I'm using Angular8, and I'm trying to open the component dynamically form another module, In this case, you need to import the module into the module that's trying to open the component, of course in addition to export the component and list it into the entryComponents array as the previous answers did.

imports: [
    ...
    TheModuleThatOwnTheTargetedComponent,
    ...
  ],

The issue with reading lines in first pass and making changes (deleting specific lines) in the second pass is that if you file sizes are huge, you will run out of RAM. Instead, a better approach is to read lines, one by one, and write them into a separate file, eliminating the ones you don't need. I have run this approach with files as big as 12-50 GB, and the RAM usage remains almost constant. Only CPU cycles show processing in progress.

I am updating one news here. Using 'prefs:' only is NOT rejected by Apple, I tested it and checked approved to the app store(in Aug, 2016). thx.

The COM threading model is called an "apartment" model, where the execution context of initialized COM objects is associated with either a single thread (Single Thread Apartment) or many threads (Multi Thread Apartment). In this model, a COM object, once initialized in an apartment, is part of that apartment for the duration of its runtime.

The STA model is used for COM objects that are not thread safe. That means they do not handle their own synchronization. A common use of this is a UI component. So if another thread needs to interact with the object (such as pushing a button in a form) then the message is marshalled onto the STA thread. The windows forms message pumping system is an example of this.

If the COM object can handle its own synchronization then the MTA model can be used where multiple threads are allowed to interact with the object without marshalled calls.

If NULL and 0 are equivalent as null pointer constants, which should I use? in the C FAQ list addresses this issue as well:

C programmers must understand that NULL and 0 are interchangeable in pointer contexts, and that an uncast 0 is perfectly acceptable. Any usage of NULL (as opposed to 0) should be considered a gentle reminder that a pointer is involved; programmers should not depend on it (either for their own understanding or the compiler's) for distinguishing pointer 0's from integer 0's.

It is only in pointer contexts that NULL and 0 are equivalent. NULL should not be used when another kind of 0 is required, even though it might work, because doing so sends the wrong stylistic message. (Furthermore, ANSI allows the definition of NULL to be ((void *)0), which will not work at all in non-pointer contexts.) In particular, do not use NULL when the ASCII null character (NUL) is desired. Provide your own definition

#define NUL '\0'

if you must.

Select by description for jQuery v1.6+

var text1 = 'Two';_x000D_
$("select option").filter(function() {_x000D_
  //may want to use $.trim in here_x000D_
  return $(this).text() == text1;_x000D_

_x000D_
<select>_x000D_
  <option value="0">One</option>_x000D_
  <option value="1">Two</option>_x000D_
</select>

jQuery versions below 1.6 and greater than or equal to 1.4

var text1 = 'Two';_x000D_
$("select option").filter(function() {_x000D_
  //may want to use $.trim in here_x000D_
  return $(this).text() == text1;_x000D_

<select>_x000D_
  <option value="0">One</option>_x000D_
  <option value="1">Two</option>_x000D_
</select>

Note that while this approach will work in versions that are above 1.6 but less than 1.9, it has been deprecated since 1.6. It will not work in jQuery 1.9+.

Previous versions

val() should handle both cases.

$('select').val('1'); // selects "Two"_x000D_
$('select').val('Two'); // also selects "Two"

IF you want more data in you confusion matrix, including "totals column" and "totals line", and percents (%) in each cell, like matlab default (see image below)

including the Heatmap and other options...

You should have fun with the module above, shared in the github ; )

https://github.com/wcipriano/pretty-print-confusion-matrix

This module can do your task easily and produces the output above with a lot of params to customize your CM:

For iOS 9 beta 3,4 users. Since the option to view profiles is not viewable do the following from Xcode.

1. Open Xcode 7.
2. Go to window, devices.
3. Select your device.
4. Delete all of the profiles loaded on the device.
5. Delete the old app on your device.
6. Clean and rebuild the app to your device.

On iOS 9.1+ n iOS 9.2+ go to Settings -> General -> Device Management -> press the Profile -> Press Trust.

If you change your function definition to use a variable instead:

var get_page = func(url string) string {
    ...
}

You can override it in your tests:

func TestDownloader(t *testing.T) {
    get_page = func(url string) string {
        if url != "expected" {
            t.Fatal("good message")
        }
        return "something"
    }
    downloader()
}

Careful though, your other tests might fail if they test the functionality of the function you override!

The Go authors use this pattern in the Go standard library to insert test hooks into code to make things easier to test:

SELECT @variable1 = col1, @variable2 = col2
FROM table1

I had the same problem. My customer ordered me Python 3.4 script that updates XLS (not XLSX) Excel files.

The 1st package xlrd was installed by "pip install" without problems in my Python home.

The 2nd one xlwt needed to say "pip install xlwt-future" to be compatible.

The 3rd one xlutils has no support for Python 3, but I adapted it a little bit and now it works at least for dummy script:

#!C:\Python343\python
from xlutils.copy import copy # http://pypi.python.org/pypi/xlutils
from xlrd import open_workbook # http://pypi.python.org/pypi/xlrd
from xlwt import easyxf # http://pypi.python.org/pypi/xlwt

file_path = 'C:\Dev\Test_upd.xls'
rb = open_workbook('C:\Dev\Test.xls',formatting_info=True)
r_sheet = rb.sheet_by_index(0) # read only copy to introspect the file
wb = copy(rb) # a writable copy (I can't read values out of this, only write to it)
w_sheet = wb.get_sheet(0) # the sheet to write to within the writable copy
w_sheet.write(1, 1, 'Value')
wb.save(file_path)

I attached the file here: http://ifolder.su/43507580

Write to [email protected] if it got expired.

P.S.: Some functions are not called in the dummy example, so maybe they will need for an adaptation also. Who wants to do it, fix exceptions one-by-one with a google help. It's not a very difficult task, because the package code is small...

You can simply use theatol()function:

#include <stdio.h>
#include <stdlib.h>

int main() 
{
    const char *c = "5";
    int d = atol(c);
    printf("%d\n", d);

}

Input Dimension Clarified:

Not a direct answer, but I just realized the word Input Dimension could be confusing enough, so be wary:

It (the word dimension alone) can refer to:

a) The dimension of Input Data (or stream) such as # N of sensor axes to beam the time series signal, or RGB color channel (3): suggested word=> "InputStream Dimension"

b) The total number /length of Input Features (or Input layer) (28 x 28 = 784 for the MINST color image) or 3000 in the FFT transformed Spectrum Values, or

"Input Layer / Input Feature Dimension"

c) The dimensionality (# of dimension) of the input (typically 3D as expected in Keras LSTM) or (#RowofSamples, #of Senors, #of Values..) 3 is the answer.

"N Dimensionality of Input"

d) The SPECIFIC Input Shape (eg. (30,50,50,3) in this unwrapped input image data, or (30, 250, 3) if unwrapped Keras:

Keras has its input_dim refers to the Dimension of Input Layer / Number of Input Feature

model = Sequential()
model.add(Dense(32, input_dim=784))  #or 3 in the current posted example above
model.add(Activation('relu'))

In Keras LSTM, it refers to the total Time Steps

The term has been very confusing, is correct and we live in a very confusing world!!

I find one of the challenge in Machine Learning is to deal with different languages or dialects and terminologies (like if you have 5-8 highly different versions of English, then you need to very high proficiency to converse with different speakers). Probably this is the same in programming languages too.

I have similar problems, in my case seem to be related to network connectivity:

Error Domain=NSURLErrorDomain Code=-1001 "The request timed out."

Things to check:

• Is there any chance that your server is not able to respond within some time limit? Like 60 seconds or 4 minutes?
• Is there a possibility that your device is switching networks (WiFi, 3G, VPN)?
• Could someone (client vs. server) be waiting for authentication?

Sorry, no ideas how to fix. Just debugging this, trying to find out what the problem is (-1021, -1001, -1009)

Update: Google search was very kind to find this:

• -1001 TimedOut - it took longer than the timeout which was alotted.
• -1003 CannotFindHost - the host could not be found.
• -1004 CannotConnectToHost - the host would not let us establish a connection.

It is simply possible with childElementCount in pure javascript

var countItems = document.getElementsByTagName("ul")[0].childElementCount;_x000D_
console.log(countItems);

<div id="selected">_x000D_
  <ul>_x000D_
    <li>29</li>_x000D_
    <li>16</li>_x000D_
    <li>5</li>_x000D_
    <li>8</li>_x000D_
    <li>10</li>_x000D_
    <li>7</li>_x000D_
  </ul>_x000D_
</div>

I took the above lattice example and made a nifty function. There is probably a better way to do this with reshape via melt/cast. (Comment or edit if you see an improvement.)

multi.density.plot=function(data,main=paste(names(data),collapse = ' vs '),...){
  ##combines multiple density plots together when given a list
  df=data.frame();
  for(n in names(data)){
    idf=data.frame(x=data[[n]],label=rep(n,length(data[[n]])))
    df=rbind(df,idf)
  }
  densityplot(~x,data=df,groups = label,plot.points = F, ref = T, auto.key = list(space = "right"),main=main,...)
}

Example usage:

multi.density.plot(list(BN1=bn1$V1,BN2=bn2$V1),main='BN1 vs BN2')

multi.density.plot(list(BN1=bn1$V1,BN2=bn2$V1))

In C, use

#include <float.h>

const double lowest_double = -DBL_MAX;

In C++pre-11, use

#include <limits>

const double lowest_double = -std::numeric_limits<double>::max();

In C++11 and onwards, use

#include <limits>

constexpr double lowest_double = std::numeric_limits<double>::lowest();
