The most recent versions of the PicklingTools libraries (1.3.0 and 1.3.1) support tools for converting from XML to a Python dict.

The download is available here: PicklingTools 1.3.1

There is quite a bit of documentation for the converters here: the documentation describes in detail all of the decisions and issues that will arise when converting between XML and Python dictionaries (there are a number of edge cases: attributes, lists, anonymous lists, anonymous dicts, eval, etc. that most converters don't handle). In general, though, the converters are easy to use. If an 'example.xml' contains:

<top>
  <a>1</a>
  <b>2.2</b>
  <c>three</c>
</top>

Then to convert it to a dictionary:

>>> from xmlloader import *
>>> example = file('example.xml', 'r')   # A document containing XML
>>> xl = StreamXMLLoader(example, 0)     # 0 = all defaults on operation
>>> result = xl.expect XML()
>>> print result
{'top': {'a': '1', 'c': 'three', 'b': '2.2'}}

There are tools for converting in both C++ and Python: the C++ and Python do indentical conversion, but the C++ is about 60x faster

I think I have found a better way. You don't have to put attributes into your classes. I've made two methods for serialization and deserialization which take generic list as parameter.

Take a look (it works for me):

private void SerializeParams<T>(XDocument doc, List<T> paramList)
    {
        System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(paramList.GetType());

        System.Xml.XmlWriter writer = doc.CreateWriter();

        serializer.Serialize(writer, paramList);

        writer.Close();           
    }

private List<T> DeserializeParams<T>(XDocument doc)
    {
        System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(List<T>));

        System.Xml.XmlReader reader = doc.CreateReader();

        List<T> result = (List<T>)serializer.Deserialize(reader);
        reader.Close();

        return result;
    }

So you can serialize whatever list you want! You don't need to specify the list type every time.

        List<AssemblyBO> list = new List<AssemblyBO>();
        list.Add(new AssemblyBO());
        list.Add(new AssemblyBO() { DisplayName = "Try", Identifier = "243242" });
        XDocument doc = new XDocument();
        SerializeParams<T>(doc, list);
        List<AssemblyBO> newList = DeserializeParams<AssemblyBO>(doc);

Your classes should look like this

[XmlRoot("StepList")]
public class StepList
{
    [XmlElement("Step")]
    public List<Step> Steps { get; set; }
}

public class Step
{
    [XmlElement("Name")]
    public string Name { get; set; }
    [XmlElement("Desc")]
    public string Desc { get; set; }
}

Here is my testcode.

string testData = @"<StepList>
                        <Step>
                            <Name>Name1</Name>
                            <Desc>Desc1</Desc>
                        </Step>
                        <Step>
                            <Name>Name2</Name>
                            <Desc>Desc2</Desc>
                        </Step>
                    </StepList>";

XmlSerializer serializer = new XmlSerializer(typeof(StepList));
using (TextReader reader = new StringReader(testData))
{
    StepList result = (StepList) serializer.Deserialize(reader);
}

If you want to read a text file you should load the file into a FileStream and deserialize this.

using (FileStream fileStream = new FileStream("<PathToYourFile>", FileMode.Open)) 
{
    StepList result = (StepList) serializer.Deserialize(fileStream);
}

See if this helps:

[Serializable()]
[System.Xml.Serialization.XmlRootAttribute("Cars", Namespace = "", IsNullable = false)]
public class Cars
{
    [XmlArrayItem(typeof(Car))]
    public Car[] Car { get; set; }
}

.

[Serializable()]
public class Car
{
    [System.Xml.Serialization.XmlElement()]
    public string StockNumber{ get; set; }

    [System.Xml.Serialization.XmlElement()]
    public string Make{ get; set; }

    [System.Xml.Serialization.XmlElement()]
    public string Model{ get; set; }
}

And failing that use the xsd.exe program that comes with visual studio to create a schema document based on that xml file, and then use it again to create a class based on the schema document.

I tried

Document.getElementsByClassName('option0')

Which resulted in the error: Uncaught TypeError: Document.getElementsByClass is not a function

After that I tried:

document.getElementsByClassName('option0')

And it works!

Below is how I got this working.

The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.

[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]

[HttpPost]  
  public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)  
  {            
     var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
     return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
  }

The JQuery script used to call this action method:

var requestData = {
         InvoiceNumber: $.trim(this.value),
         SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())
      };


      $.ajax({
         url: '/en/myController/GetDataForInvoiceNumber',
         type: 'POST',
         data: JSON.stringify(requestData),
         dataType: 'json',
         contentType: 'application/json; charset=utf-8',
         error: function (xhr) {
            alert('Error: ' + xhr.statusText);
         },
         success: function (result) {
            CheckIfInvoiceFound(result);
         },
         async: true,
         processData: false
      });

See LINQ: How to get the latest/last record with a group by clause

var firstItemsInGroup = from b in mainButtons
                 group b by b.category into g
select g.First();

I assume that mainButtons are already sorted correctly.

If you need to specify custom sort order, use OrderBy override with Comparer.

var firstsByCompareInGroups = from p in rows
        group p by p.ID into grp
        select grp.OrderBy(a => a, new CompareRows()).First();

See an example in my post "Select First Row In Group using Custom Comparer"

You could do something like this

String[] myStrings = { "One", "Two", "Three" };

or in expression

functionCall(new String[] { "One", "Two", "Three" });

or

String myStrings[];
myStrings = new String[] { "One", "Two", "Three" };

this worked for me..

<Location />
 Allow from all
 Order Deny,Allow
</Location>

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

use

pattern.compile("\"");
String s= p.toString()+"yourcontent"+p.toString();

will give result as yourcontent as is

If you're using version 3.x of Bootstrap, the correct way to do this now is:

$('#myModal').on('hidden.bs.modal', function (e) {
  // do something...
})

Scroll down to the events section to learn more.

http://getbootstrap.com/javascript/#modals-usage

This appears to remain unchanged for whenever version 4 releases (http://v4-alpha.getbootstrap.com/components/modal/#events), but if it does I'll be sure to update this post with the relevant information.

This is happening because of the CORS error. CORS stands for Cross Origin Resource Sharing. In simple words, this error occurs when we try to access a domain/resource from another domain.

Read More about it here: CORS error with jquery

To fix this, if you have access to the other domain, you will have to allow Access-Control-Allow-Origin in the server. This can be added in the headers. You can enable this for all the requests/domains or a specific domain.

Try

$(document).ready(function(){
    //Register click events to all checkboxes inside question element
    $(document).on('click', '.question input:checkbox', function() {
        //Find the next answer element to the question and based on the checked status call either show or hide method
        $(this).closest('.question').next('.answer')[this.checked? 'show' : 'hide']()
    });

});

Demo: Fiddle

Or

$(document).ready(function(){
    //Register click events to all checkboxes inside question element
    $(document).on('click', '.question input:checkbox', function() {
        //Find the next answer element to the question and based on the checked status call either show or hide method

});

Following the JSON-P 1.0 specs (JSR-353) a more current solution for a given JsonStructure (JsonObject or JsonArray) could look like this:

import java.io.StringWriter;
import java.util.HashMap;
import java.util.Map;

import javax.json.Json;
import javax.json.JsonStructure;
import javax.json.JsonWriter;
import javax.json.JsonWriterFactory;
import javax.json.stream.JsonGenerator;

public class PrettyJson {

    private static JsonWriterFactory FACTORY_INSTANCE;

    public static String toString(final JsonStructure status) {

        final StringWriter stringWriter = new StringWriter();

        final JsonWriter jsonWriter = getPrettyJsonWriterFactory()
                .createWriter(stringWriter);

        jsonWriter.write(status);
        jsonWriter.close();

        return stringWriter.toString();
    }

    private static JsonWriterFactory getPrettyJsonWriterFactory() {
        if (null == FACTORY_INSTANCE) {
            final Map<String, Object> properties = new HashMap<>(1);
            properties.put(JsonGenerator.PRETTY_PRINTING, true);
            FACTORY_INSTANCE = Json.createWriterFactory(properties);
        }
        return FACTORY_INSTANCE;
    }

}

collection.ToList().ForEach(c => c.PropertyToSet = value);

Following query helped me. Instead of using LIKE, you can use ~*.

select id, name from hosts where name ~* 'julia|lena|jack';

Use method=POST then it will pass key&value.

When you use DISTINCT think of it as a distinct row, not column. It will return only rows where the columns do not match exactly the same.

SELECT DISTINCT ID, Email, ProductName, ProductModel
FROM Products

----------------------
1 | [email protected] | ProductName1 | ProductModel1
2 | [email protected] | ProductName1 | ProductModel1

The query would return both rows because the ID column is different. I'm assuming that the ID column is an IDENTITY column that is incrementing, if you want to return the last then I recommend something like this:

SELECT DISTINCT TOP 1 ID, Email, ProductName, ProductModel
FROM Products
ORDER BY ID DESC

The TOP 1 will return only the first record, by ordering it by the ID descending it will return the results with the last row first. This will give you the last record.

The function I use currently:

/**
 * Serializes form or any other element with jQuery.serialize
 * @param el
 */
serialize: function(el) {
    var serialized = $(el).serialize();
    if (!serialized) // not a form
        serialized = $(el).
          find('input[name],select[name],textarea[name]').serialize();
    return serialized;
}

try this....

  public  void buildPushNotification(Context ctx, String content, int icon, CharSequence text, boolean silent) {
    Intent intent = new Intent(ctx, Activity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(ctx, 1410, intent, PendingIntent.FLAG_ONE_SHOT);

    Bitmap bm = BitmapFactory.decodeResource(ctx.getResources(), //large drawable);

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(ctx)
            .setSmallIcon(icon)
            .setLargeIcon(bm)
            .setContentTitle(content)
            .setContentText(text)
            .setAutoCancel(true)
            .setContentIntent(pendingIntent);

    if(!silent)
       notificationBuilder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));

 NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(1410, notificationBuilder.build());
    }

and in onMessageReceived, call it

 @Override
public void onMessageReceived(RemoteMessage remoteMessage) {


    Log.d("Msg", "Message received [" + remoteMessage.getNotification().getBody() + "]");

    buildPushNotification(/*your param*/);
}

or follow KongJing, Is also correct as he says, but you can use a Firebase Console.

Instead of using the instance with the scope resolution operator :: because it wasn't defined like static function.

$r=Page::getInstanceByName($page);

change it to :

$r=Page->getInstanceByName($page);

And it will work like a charm.

the following bitwise operators: &, |, ^, and ~ return values (based on their input) in the same way logic gates affect signals. You could use them to emulate circuits.

select convert(varchar(11), transfer_date, 106)

got me my desired result of date formatted as 07 Mar 2018

My column 'transfer_date' is a datetime type column and I am using SQL Server 2017 on azure

while true; do foo; sleep 2; done

By the way, if you type it as a multiline (as you are showing) at the command prompt and then call the history with arrow up, you will get it on a single line, correctly punctuated.

$ while true
> do
>    echo "hello"
>    sleep 2
> done
hello
hello
hello
^C
$ <arrow up> while true; do    echo "hello";    sleep 2; done

The shift can be implement with data types (char, int and long int). The float and double data connot be shifted.

value= value >> steps  // Right shift, signed data.
value= value << steps  // Left shift, signed data.

Not possible with vanilla CSS. However you can use something like:

• Sass

Sass makes CSS fun again. Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It’s translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.

Or

• Less

Rather than constructing long selector names to specify inheritance, in Less you can simply nest selectors inside other selectors. This makes inheritance clear and style sheets shorter.

Example:

#header {
  color: red;
  a {
    font-weight: bold;
    text-decoration: none;
  }
}

1. Select cell B3 and click the Conditional Formatting button in the ribbon and choose "New Rule".
2. Select "Use a formula to determine which cells to format"
3. Enter the formula: =IF(B2="X",IF(B3="Y", TRUE, FALSE),FALSE), and choose to fill green when this is true
4. Create another rule and enter the formula =IF(B2="X",IF(B3="W", TRUE, FALSE),FALSE) and choose to fill red when this is true.

More details - conditional formatting with a formula applies the format when the formula evaluates to TRUE. You can use a compound IF formula to return true or false based on the values of any cells.

WARNING: Not for git newbies.

This comes up enough in my workflow that I've almost tried to write a new git command for it. The usual git stash flow is the way to go but is a little awkward. I usually make a new commit first since if I have been looking at the changes, all the information is fresh in my mind and it's better to just start git commit-ing what I found (usually a bugfix belonging on master that I discover while working on a feature branch) right away.

It is also helpful—if you run into situations like this a lot—to have another working directory alongside your current one that always have the master branch checked out.

So how I achieve this goes like this:

1. git commit the changes right away with a good commit message.
2. git reset HEAD~1 to undo the commit from current branch.
3. (optional) continue working on the feature.

Sometimes later (asynchronously), or immediately in another terminal window:

1. cd my-project-master which is another WD sharing the same .git
2. git reflog to find the bugfix I've just made.
3. git cherry-pick SHA1 of the commit.

Optionally (still asynchronous) you can then rebase (or merge) your feature branch to get the bugfix, usually when you are about to submit a PR and have cleaned your feature branch and WD already:

1. cd my-project which is the main WD I'm working on.
2. git rebase master to get the bugfixes.

This way I can keep working on the feature uninterrupted and not have to worry about git stash-ing anything or having to clean my WD before a git checkout (and then having the check the feature branch backout again.) and still have all my bugfixes goes to master instead of hidden in my feature branch.

IMO git stash and git checkout is a real PIA when you are in the middle of working on some big feature.

Thanks for the solution !

It works, but in a french Excel environment, you should apply something like

TEXTE(F2;"jj/mm/aaaa")

to get the date preserved as it is displayed in F2 cell, after concatenation. Best Regards

I have a different take on this. I could do a docker ps and see that there is a docker container running, I even tried to restart it, but as soon as I tried to get a session for it with New-PSSession -ContainerId $containerId -RunAsAdministrator It would error out, saying:

##[error]New-PSSession : The input ContainerId xxx does not exist, ##[error]or the corresponding container is not running.

My problem was I was running with network service and it did not have enough permissions to see the container, even though I had given it permissions to run docker commands (with docker security group configuration)

I didn't know how to enable working with containers, so I had to revert to running it as an admin user instead

Tangential: String.format() rocks:

public String toString() {
    return String.format("%s %s", getMake(), getReg());
}

private static void printAll() {
    for (Car car: cars)

}

Asterisk (*) works with alias. Ex:

df1 = df1.alias('df1')
df2 = df2.alias('df2')

df1.join(df2, df1.id == df2.id).select('df1.*')

You need to have a Reference to the System.Web.Http assembly which has the HTTPClient class, your trying to use. Try adding the below line before your class declaration

using System.Web.Http;

If you still get the Error, try doing this in Visual Studio

1. Right click on the References folder on your project.
2. Select Add Reference.
3. Select the .NET tab (or select the Browse button if it is not a .NET Framework assembly).
4. Double-click the assembly containing the namespace in the error message (System.Web.Http.dll).
5. Press the OK button.

For guys like me, who aren't minimalistic, there is a PECL extension called "intl". I use it for idn conversion since it works way better than the "idn" extension and some other n1 classes like "IntlDateFormatter".

Well, what I want to say is, the "intl" extension has a class called "IntlCalendar" which can handle many international countries (e.g. in Saudi Arabia, sunday is not a weekend day). The IntlCalendar has a method IntlCalendar::isWeekend for that. Maybe you guys give it a shot, I like that "it works for almost every country" fact on these intl-classes.

EDIT: Not quite sure but since PHP 5.5.0, the intl extension is bundled with PHP (--enable-intl).

A language itself is neither compiled nor interpreted, only a specific implementation of a language is. Java is a perfect example. There is a bytecode-based platform (the JVM), a native compiler (gcj) and an interpeter for a superset of Java (bsh). So what is Java now? Bytecode-compiled, native-compiled or interpreted?

Other languages, which are compiled as well as interpreted, are Scala, Haskell or Ocaml. Each of these languages has an interactive interpreter, as well as a compiler to byte-code or native machine code.

So generally categorizing languages by "compiled" and "interpreted" doesn't make much sense.

Perhaps the best two browser techs for this are Canvas, with Flash as a back up.

We tried VML on IE as backup for Canvas, but it was much slower than Flash. SVG was slower then all the rest.

With jSignature ( http://willowsystems.github.com/jSignature/ ) we used Canvas as primary, with fallback to Flash-based Canvas emulator (FlashCanvas) for IE8 and less. Id' say worked very well for us.

Insert Into FEMALE(ID, Image)
Select '1', BulkColumn 
from Openrowset (Bulk 'D:\thepathofimage.jpg', Single_Blob) as Image

You will also need admin rights to run the query.

If you already have the target object, so you don't want to create it anew (like if updating an array) you must copy the properties.
If have done it this way:

Object.keys(source).forEach((key) => {
    copy[key] = source[key]
})

Praise is due. (look at headline "version 2")

You are iterating over one string (word), but then using the index into that to look up a character in so_far. There is no guarantee that these two strings have the same length.

In bootstrap 4.1, the w-100 class is required along with img-fluid for images smaller than the page to be stretched:

<div class="container">
  <div class="row">
    <img class='img-fluid w-100' src="#" alt="" />
  </div>
</div>

see closed issue: https://github.com/twbs/bootstrap/issues/20830

(As of 2018-04-20, the documentation is wrong: https://getbootstrap.com/docs/4.1/content/images/ says that img-fluid applies max-width: 100%; height: auto;" but img-fluid does not resolve the issue, and neither does manually adding those style attributes with or without bootstrap classes on the img tag.)

To use function LEFT if not all data is in the form '1/12' you need this in the second line above:

Set Col2 = LEFT(Col1, ISNULL(NULLIF(CHARINDEX('/', Col1) - 1, -1), LEN(Col1)))

  function nextFormInput() {
      var focused = $(':focus');
      var inputs = $(focused).closest('form').find(':input');
      inputs.eq(inputs.index(focused) + 1).focus();
  }

Just wanted to add to this since I ran into the same problem and nothing I could find anywhere would work (e.g downloading the cacert.pem file, setting cafile in php.ini etc.)

If you are using NGINX and your SSL certificate comes with an "intermediate certificate", you need to combine the intermediate cert file with your main "mydomain.com.crt" file and it should work. Apache has a setting specific for intermediate certs, but NGINX does not so it must be within same file as your regular cert.

You may be able to use the JAVA_TOOL_OPTIONS environment variable to set options. It worked for me with Rasbian. See Environment Variables and System Properties which has this to say:

In many environments, the command line is not readily accessible to start the application with the necessary command-line options.

This often happens with applications that use embedded VMs (meaning they use the Java Native Interface (JNI) Invocation API to start the VM), or where the startup is deeply nested in scripts. In these environments the JAVA_TOOL_OPTIONS environment variable can be useful to augment a command line.

When this environment variable is set, the JNI_CreateJavaVM function (in the JNI Invocation API), the JNI_CreateJavaVM function adds the value of the environment variable to the options supplied in its JavaVMInitArgs argument.

However this environment variable use may be disabled for security reasons.

In some cases, this option is disabled for security reasons. For example, on the Oracle Solaris operating system, this option is disabled when the effective user or group ID differs from the real ID.

See this example showing the difference between specifying on the command line versus using the JAVA_TOOL_OPTIONS environment variable.

1) JTable knows JCheckbox with built-in Boolean TableCellRenderers and TableCellEditor by default, then there is contraproductive declare something about that,

2) AbstractTableModel should be useful, where is in the JTable required to reduce/restrict/change nested and inherits methods by default implemented in the DefaultTableModel,

3) consider using DefaultTableModel, (if you are not sure about how to works) instead of AbstractTableModel,

could be generated from simple code:

We've seen in our projects that a post request with JSON and files is creating a lot of confusion between the frontend and backend developers, leading to unnecessary wastage of time.

Here's a better approach: convert file bytes array to Base64 string and send it in the JSON.

public Class UserDTO {
    private String firstName;
    private String lastName;
    private FileDTO profilePic; 
}

public class FileDTO {
    private String base64;
    // just base64 string is enough. If you want, send additional details
    private String name;
    private String type;
    private String lastModified;
}

@PostMapping("/user")
public String saveUser(@RequestBody UserDTO user) {
    byte[] fileBytes = Base64Utils.decodeFromString(user.getProfilePic().getBase64());
    ....
}

JS code to convert file to base64 string:

var reader = new FileReader();
reader.readAsDataURL(file);
reader.onload = function () {

  const userDTO = {
    firstName: "John",
    lastName: "Wick",
    profilePic: {
      base64: reader.result,
      name: file.name,
      lastModified: file.lastModified,
      type: file.type
    }
  }
  
  // post userDTO
};
reader.onerror = function (error) {
  console.log('Error: ', error);
};

np.isnan can be applied to NumPy arrays of native dtype (such as np.float64):

In [99]: np.isnan(np.array([np.nan, 0], dtype=np.float64))
Out[99]: array([ True, False], dtype=bool)

but raises TypeError when applied to object arrays:

In [96]: np.isnan(np.array([np.nan, 0], dtype=object))
TypeError: ufunc 'isnan' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''

Since you have Pandas, you could use pd.isnull instead -- it can accept NumPy arrays of object or native dtypes:

In [97]: pd.isnull(np.array([np.nan, 0], dtype=float))
Out[97]: array([ True, False], dtype=bool)

In [98]: pd.isnull(np.array([np.nan, 0], dtype=object))
Out[98]: array([ True, False], dtype=bool)

Note that None is also considered a null value in object arrays.

it is easy! you are downloading the binary file?. download the rpm latest package openssl-1.0.1e-30.el6.x86_64 check what was the current version using rpm -q openssl. if this is older then do rpm -U openssl-1.0.1e-30.el6.x86_64 . if yum is configured updated this package in the repo and do yum update openssl if your repo in RHN do simply yum update openssl-1.0.1g is very old and valnuarable

Yes, but the syntax is different than what you have

SELECT
    <fields>
FROM
    <table1>
    LEFT JOIN <table2>
        ON <criteria for join>
        AND <other criteria for join>
    LEFT JOIN <table3> 
        ON <criteria for join>
        AND <other criteria for join>

As Darin says, you can read from the input stream - but I'd avoid relying on all the data being available in a single go. If you're using .NET 4 this is simple:

MemoryStream target = new MemoryStream();
model.File.InputStream.CopyTo(target);
byte[] data = target.ToArray();

It's easy enough to write the equivalent of CopyTo in .NET 3.5 if you want. The important part is that you read from HttpPostedFileBase.InputStream.

For efficient purposes you could check whether the stream returned is already a MemoryStream:

byte[] data;
using (Stream inputStream = model.File.InputStream)
{
    MemoryStream memoryStream = inputStream as MemoryStream;
    if (memoryStream == null)
    {
        memoryStream = new MemoryStream();
        inputStream.CopyTo(memoryStream);
    }
    data = memoryStream.ToArray();
}

You can temporarily disable timestamps

$timestamps = $user->timestamps;
$user->timestamps=false;   // avoid view updating the timestamp

$user->last_logged_in_at = now();
$user->save();

$user->timestamps=$timestamps;   // restore timestamps

The accepted answer by @Meherzad only works if the data is in a particular order. It happens to work with the data from the OP question. In my case, I had to modify it to work with my data.

Note This only works when every record's "id" (col1 in the question) has a value GREATER THAN that record's "parent id" (col3 in the question). This is often the case, because normally the parent will need to be created first. However if your application allows changes to the hierarchy, where an item may be re-parented somewhere else, then you cannot rely on this.

This is my query in case it helps someone; note it does not work with the given question because the data does not follow the required structure described above.

select t.col1, t.col2, @pv := t.col3 col3
from (select * from table1 order by col1 desc) t
join (select @pv := 1) tmp
where t.col1 = @pv

The difference is that table1 is being ordered by col1 so that the parent will be after it (since the parent's col1 value is lower than the child's).

The accepted answer is wrong. The quote is correct, the assertion that PUT and POST must have it is incorrect. There is no requirement that PUT or POST actually have additional content. Nor is there a prohibition against GET actually having content.

The RFCs say exactly what they mean .. IFF your side (client OR origin server) will be sending additional content, beyond the HTTP headers, it SHOULD specify a Content-Type header. But note it is allowable to omit the Content-Type and still include content (say, by using a Content-Length header).

For Each row As DataRow In dtDataTable.Rows
    strDetail = row.Item("Detail")
Next row

There's also a shorthand:

For Each row As DataRow In dtDataTable.Rows
    strDetail = row("Detail")
Next row

Note that Microsoft's style guidelines for .Net now specifically recommend against using hungarian type prefixes for variables. Instead of "strDetail", for example, you should just use "Detail".

I also ran into the similar issue and was using CNTLM for proxy configuration. In my case HTTP_PROXY and HTTPS_PROXY are taking higher precedence over http_proxy and https_proxy so be aware of changing all proxy variables.

env|grep -i proxy

and make sure all of the below proxy variables should point to the same proxy.

HTTP-PROXY = "http://localhost:3128"
HTTPS-PROXY = "https://localhost:3128"
HTTPS_PROXY = "http://localhost:3128"
HTTP_PROXY = "http://localhost:3128"
PROXY = "http://localhost:3128"
http-proxy = "http://localhost:3128"
http_proxy = "http://localhost:3128"
https-proxy = "https://localhost:3128/"
https_proxy = "https://localhost:3128"
proxy = "http://localhost:3128/"

I know some variables are unneccessary but I'm not sure which is using what.

One way to get the list of distinct column names from the database is to use distinct() in conjunction with values().

In your case you can do the following to get the names of distinct categories:

q = ProductOrder.objects.values('Category').distinct()
print q.query # See for yourself.

# The query would look something like
# SELECT DISTINCT "app_productorder"."category" FROM "app_productorder"

There are a couple of things to remember here. First, this will return a ValuesQuerySet which behaves differently from a QuerySet. When you access say, the first element of q (above) you'll get a dictionary, NOT an instance of ProductOrder.

Second, it would be a good idea to read the warning note in the docs about using distinct(). The above example will work but all combinations of distinct() and values() may not.

PS: it is a good idea to use lower case names for fields in a model. In your case this would mean rewriting your model as shown below:

class ProductOrder(models.Model):
    product  = models.CharField(max_length=20, primary_key=True)
    category = models.CharField(max_length=30)
    rank = models.IntegerField()

Primary keys are for uniquely identifying rows. This is done by comparing all parts of a key to the input.

Per definition, NULL cannot be part of a successful comparison. Even a comparison to itself (NULL = NULL) will fail. This means a key containing NULL would not work.

Additonally, NULL is allowed in a foreign key, to mark an optional relationship.^(*) Allowing it in the PK as well would break this.

^(*)A word of caution: Having nullable foreign keys is not clean relational database design.

If there are two entities A and B where A can optionally be related to B, the clean solution is to create a resolution table (let's say AB). That table would link A with B: If there is a relationship then it would contain a record, if there isn't then it would not.

Another nice way to deal with JSON data is using the JQuery getJSON function. You can call the

public ActionResult SomeActionMethod(int id) 
{ 
    return Json(new {foo="bar", baz="Blech"});
}

Method from the jquery getJSON method by simply...

$.getJSON("../SomeActionMethod", { id: someId },
    function(data) {
        alert(data.foo);
        alert(data.baz);
    }
);

You can definitely go for typeid(x).name() where x is the variable name. It actually returns a const char pointer to the data type. Now, look at the following code.

#include<bits/stdc++.h>
using namespace std;
int main()
{
    int n = 36;
    char c = 'A';
    double d = 1.2;
    if(*(typeid(n).name()) == 'i'){
        cout << "I am an Integer variable" << endl;
    }
    if(*((char *) typeid(d).name()) == 'd'){
        cout << "I am a Double variable" << endl;
    }
    if(*((char *) typeid(c).name()) == 'c'){
        cout << "I am a Char variable" << endl;
    }
    return 0;
}

Notice how first and second both if works.

Executing seq(1, 10, 1) does what 1:10 does. You can change the last parameter of seq, i.e. by, to be the step of whatever size you like.

> #a vector of even numbers
> seq(0, 10, by=2) # Explicitly specifying "by" only to increase readability 
> [1]  0  2  4  6  8 10

Get the current URL including the query string.

echo url()->full();

INSERT INTO target( userid, rightid, count )
  SELECT userid, rightid, count 
  FROM batch
  WHERE NOT EXISTS (
    SELECT * FROM target t2, batch b2
    WHERE t2.userid = b2.userid
    -- ... other keyfields ...
    )       
    ;

BTW: if you want the whole batch to fail in case of a duplicate, then (given a primary key constraint)

INSERT INTO target( userid, rightid, count )
SELECT userid, rightid, count 
FROM batch
    ;

will do exactly what you want: either it succeeds, or it fails.

In mathematics the result of the modulo operation is the remainder of the Euclidean division. However, other conventions are possible. Computers and calculators have various ways of storing and representing numbers; thus their definition of the modulo operation depends on the programming language and/or the underlying hardware.

 7 modulo  3 -->  1  
 7 modulo -3 --> -2 
-7 modulo  3 -->  2  
-7 modulo -3 --> -1 

It can depend on what your are initialising, for example you cannot just use field initialisation if a checked exception is involved. For example, the following:

public class Foo {
    FileInputStream fis = new FileInputStream("/tmp"); // throws FileNotFoundException
}

Will cause a compile-time error unless you also include a constructor declaring that checked exception, or extend a superclass which does, e.g.:

public Foo() throws FileNotFoundException {} 

I think the reason may be that mock object libraries typically create mocks by dynamically creating classes at runtime (using cglib). This means they either implement an interface at runtime (that's what EasyMock does if I'm not mistaken), or they inherit from the class to mock (that's what Mockito does if I'm not mistaken). Both approaches do not work for static members, since you can't override them using inheritance.

The only way to mock statics is to modify a class' byte code at runtime, which I suppose is a little more involved than inheritance.

That's my guess at it, for what it's worth...

The broken pipe error usually occurs if your request is blocked or takes too long and after request-side timeout, it'll close the connection and then, when the respond-side (server) tries to write to the socket, it will throw a pipe broken error.

{{ (ability.id in company_abilities) ? 'selected' : '' }}

The ternary operator is documented under 'other operators'

You can do it with a sub-query:

SELECT * FROM (
    SELECT * FROM table ORDER BY id DESC LIMIT 50
) sub
ORDER BY id ASC

This will select the last 50 rows from table, and then order them in ascending order.

I've written a gem that does this for Rails ActiveRecord objects. The example uses created_at, but it will also work on updated_at or anything with the class ActiveSupport::TimeWithZone.

Just gem install and call the 'pretty' method on your TimeWithZone instance.

The workaround is simple. Just use the Uri().ToString() method and percent-encode white-spaces, if any, afterwards.

string path = new Uri("C:\my example?.txt").ToString().Replace(" ", "%20");

I added to my .env file the details of the mail service I am using. So make sure the following details

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587

NOTE: Don't forget to restart your server after editing the .env file so it will pick the new data that you put in there.

Clear config cache with below command:

php artisan config:cache

If you don't restart your server, the .env file will still continue to present the old mail data to the app even though you have made changes that can cause this error.

There is no semantic difference in the generic constraint language between whether a class 'implements' or 'extends'. The constraint possibilities are 'extends' and 'super' - that is, is this class to operate with assignable to that other one (extends), or is this class assignable from that one (super).

encode function can help you here, encode returns an encoded version of the string

In [44]: str = "ABCD"

In [45]: [elem.encode("hex") for elem in str]

If you anticipate this rather unwanted behaviour, then one away around it would be to pass an extra parameter from the jQuery.trigger() to the checkbox's click handler. This extra parameter is to notify the click handler that click has been triggered programmatically, rather than by the user directly clicking on the checkbox itself. The checkbox's click handler can then invert the reported check status.

So here's how I'd trigger the click event on a checkbox with the ID "myCheckBox". Note that I'm also passing an object parameter with an single member, nonUI, which is set to true:

$("#myCheckbox").trigger('click', {nonUI : true})

And here's how I handle that in the checkbox's click event handler. The handler function checks for the presence of the nonUI object as its second parameter. (The first parameter is always the event itself.) If the parameter is present and set to true then I invert the reported .checked status. If no such parameter is passed in - which there won't be if the user simply clicked on the checkbox in the UI - then I report the actual .checked status:

$("#myCheckbox").click(function(e, parameters) {
   var nonUI = false;
        try {
            nonUI = parameters.nonUI;
        } catch (e) {}
        var checked = nonUI ? !this.checked : this.checked;
        alert('Checked = ' + checked);
    });

What worked well for me was to use this solution:

You can paste that into a .bat file and double-click on it.

I have encountered the same problem, but with an additional constraint: I had no control over the code that appended new elements to the scroll container. None of the examples I found here allowed me to do just that. Here is the solution I ended up with .

It uses Mutation Observers (https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver) which makes it usable only on modern browsers (though polyfills exist)

So basically the code does just that :

var scrollContainer = document.getElementById("myId");

// Define the Mutation Observer
var observer = new MutationObserver(function(mutations) {

  // Compute sum of the heights of added Nodes
  var newNodesHeight = mutations.reduce(function(sum, mutation) {
      return sum + [].slice.call(mutation.addedNodes)
        .map(function (node) { return node.scrollHeight || 0; })
        .reduce(function(sum, height) {return sum + height});
  }, 0);

  // Scroll to bottom if it was already scrolled to bottom
  if (scrollContainer.clientHeight + scrollContainer.scrollTop + newNodesHeight + 10 >= scrollContainer.scrollHeight) {
    scrollContainer.scrollTop = scrollContainer.scrollHeight;
  }

});

// Observe the DOM Element
observer.observe(scrollContainer, {childList: true});

I made a fiddle to demonstrate the concept : https://jsfiddle.net/j17r4bnk/

FYI I did a little research as well and if the name of the font-family you want to apply contains spaces (as an example I take Gill Alt One MT Light), you should write it this way :

strbody= "<BODY style=" & Chr(34) & "font-family:Gill Alt One MT Light" & Chr(34) & ">" & YOUR_TEXT & "</BODY>"

The cleanest approach is to copy the list and then insert the object into the copy. On Python 3 this can be done via list.copy:

new = old.copy()
new.insert(index, value)

On Python 2 copying the list can be achieved via new = old[:] (this also works on Python 3).

In terms of performance there is no difference to other proposed methods:

$ python --version
Python 3.8.1
$ python -m timeit -s "a = list(range(1000))" "b = a.copy(); b.insert(500, 3)"
100000 loops, best of 5: 2.84 µsec per loop
$ python -m timeit -s "a = list(range(1000))" "b = a.copy(); b[500:500] = (3,)"
100000 loops, best of 5: 2.76 µsec per loop

Use Timer for every second...

new Timer().scheduleAtFixedRate(new TimerTask() {
    @Override
    public void run() {
        //your method
    }
}, 0, 1000);//put here time 1000 milliseconds=1 second

The tabularx package gives you

1. the total width as a first parameter, and
2. a new column type X, all X columns will grow to fill up the total width.

For your example:

\usepackage{tabularx}

\begin{document}
% ...

\begin{tabularx}{\textwidth}{|X|X|X|}
\hline
Input & Output& Action return \\
\hline
\hline
DNF &  simulation & jsp\\
\hline
\end{tabularx}

Just call plt.show() at the end:

import numpy as np
import matplotlib.pyplot as plt

plt.axis([0,50,60,80])
for i in np.arange(1,5):
    z = 68 + 4 * np.random.randn(50)
    zm = np.cumsum(z) / range(1,len(z)+1)
    plt.plot(zm)    

n = np.arange(1,51)
su = 68 + 4 / np.sqrt(n)
sl = 68 - 4 / np.sqrt(n)

plt.plot(n,su,n,sl)

plt.show()

To drop a UNIQUE constraint, you don’t need the name of the constraint, just the list of columns that are included in the constraint.

The syntax would be:

ALTER TABLE table_name DROP UNIQUE (column1, column2, . . . )

I would suggest the following pattern:

document.getElementById("foo").onsubmit = function(e) {
    if (document.getElementById("test").value == "test") {
        return true;
    } else {
        e.preventDefault();
    }
}

<form id="foo">
    <input id="test"/>
    <input type="submit"/>
</form>

...unless I'm missing something.

Note the JsonSerializerSettings instance passed as the second parameter. That's what makes the camelCase happen.

Replace %VAR% with your directory. Please read the original answer because includes details about handling white spaces in the folder name.

As foxidrive said, this might not be reliable on NT class windows. It works for me, but I know it has some limitations (which you can find in the referenced question)

if exist "c:\folder\" echo folder exists 

should be enough for modern windows.

Try this. Just pass in the param you want to remove from the URL and the original URL value, and the function will strip it out for you.

function removeParam(key, sourceURL) {
    var rtn = sourceURL.split("?")[0],
        param,
        params_arr = [],
        queryString = (sourceURL.indexOf("?") !== -1) ? sourceURL.split("?")[1] : "";
    if (queryString !== "") {
        params_arr = queryString.split("&");
        for (var i = params_arr.length - 1; i >= 0; i -= 1) {
            param = params_arr[i].split("=")[0];
            if (param === key) {
                params_arr.splice(i, 1);
            }
        }
        if (params_arr.length) rtn = rtn + "?" + params_arr.join("&");
    }
    return rtn;
}

To use it, simply do something like this:

var originalURL = "http://yourewebsite.com?id=10&color_id=1";
var alteredURL = removeParam("color_id", originalURL);

The var alteredURL will be the output you desire.

Hope it helps!

The simplest way would be to directly subtract the date objects from one another.

For example:

var hours = Math.abs(date1 - date2) / 36e5;

The subtraction returns the difference between the two dates in milliseconds. 36e5 is the scientific notation for 60*60*1000, dividing by which converts the milliseconds difference into hours.

git-pull - Fetch from and integrate with another repository or a local branch GIT PULL

Basically you are pulling remote branch to your local, example:

git pull origin master

Will pull master branch into your local repository

git-rebase - Forward-port local commits to the updated upstream head GIT REBASE

This one is putting your local changes on top of changes done remotely by other users. For example:

• You have committed some changes on your local branch for example called SOME-FEATURE
• Your friend in the meantime was working on other features and he merged his branch into master

Now you want to see his and your changes on your local branch. So then you checkout master branch:

git checkout master

then you can pull:

git pull origin master

and then you go to your branch:

git checkout SOME-FEATURE

and you can do rebase master to get lastest changes from it and put your branch commits on top:

git rebase master

I hope now it's a bit more clear for you.

Above answers are pretty sufficient. Additional to the onChange, if you upload a file using drag and drop events, you can get the file in drop event by accessing eventArgs.dataTransfer.files.

You just need this:

$(".hidden").attr("placeholder", "Type here to search");

classList is used for manipulating classes and not attributes.

The major difference is time-out, WCF Service has timed-out when there is no response, but web-service does not have this property.

You can use this

(new SelectElement(driver.FindElement(By.Id(""))).SelectByText("");

• Some daemons (e.g. apache) do this by themselves by calling setuid()
• You could use the setuid-file flag to run the process as a different user.
• Of course, the solution you mentioned works as well.

If you intend to write your own daemon, then I recommend calling setuid(). This way, your process can

1. Make use of its root privileges (e.g. open log files, create pid files).
2. Drop its root privileges at a certain point during startup.

This one worked for me:

@MetricMonthNumber (some number)

SELECT 
(DateName( month , DateAdd( month , @MetricMonthNumber - 1 , '1900-01-01' ) )) AS MetricMonthName
FROM TableName

From a post above from @leoinfo and @Valentino Vranken. Just did a quick select and it works.

This API has been available for a long time and enables to get access to market data (including live) if you are running a Bloomberg Terminal or have access to a Bloomberg Server, which is chargeable.

The only difference is that the API (not its code) has been open sourced, so it can now be used as a dependency in an open source project for example, without any copyrights issues, which was not the case before.

A[A==NDV]=numpy.nan

A==NDV will produce a boolean array that can be used as an index for A

You can synchronize your code over the class. That would be simplest.

   public class Test  
    {  
       private static int count = 0;  
       private static final Object lock= new Object();    
       public synchronized void foo() 
      {  
          synchronized(Test.class)
         {  
             count++;  
         }  
      }  
    }

Hope you find this answer useful.

It sounds like you already know the unique column names. If that's the case, then df = df['Time', 'Time Relative', 'N2'] would work.

If not, your solution should work:

In [101]: vals = np.random.randint(0,20, (4,3))
          vals
Out[101]:
array([[ 3, 13,  0],
       [ 1, 15, 14],
       [14, 19, 14],
       [19,  5,  1]])

In [106]: df = pd.DataFrame(np.hstack([vals, vals]), columns=['Time', 'H1', 'N2', 'Time Relative', 'N2', 'Time'] )
          df
Out[106]:
   Time  H1  N2  Time Relative  N2  Time
0     3  13   0              3  13     0
1     1  15  14              1  15    14
2    14  19  14             14  19    14
3    19   5   1             19   5     1

In [107]: df.T.drop_duplicates().T
Out[107]:
   Time  H1  N2
0     3  13   0
1     1  15  14
2    14  19  14
3    19   5   1

You probably have something specific to your data that's messing it up. We could give more help if there's more details you could give us about the data.

Edit: Like Andy said, the problem is probably with the duplicate column titles.

For a sample table file 'dummy.csv' I made up:

Time    H1  N2  Time    N2  Time Relative
3   13  13  3   13  0
1   15  15  1   15  14
14  19  19  14  19  14
19  5   5   19  5   1

using read_table gives unique columns and works properly:

In [151]: df2 = pd.read_table('dummy.csv')
          df2
Out[151]:
         Time  H1  N2  Time.1  N2.1  Time Relative
      0     3  13  13       3    13              0
      1     1  15  15       1    15             14
      2    14  19  19      14    19             14
      3    19   5   5      19     5              1
In [152]: df2.T.drop_duplicates().T
Out[152]:
             Time  H1  Time Relative
          0     3  13              0
          1     1  15             14
          2    14  19             14
          3    19   5              1  

If your version doesn't let your, you can hack together a solution to make them unique:

In [169]: df2 = pd.read_table('dummy.csv', header=None)
          df2
Out[169]:
              0   1   2     3   4              5
        0  Time  H1  N2  Time  N2  Time Relative
        1     3  13  13     3  13              0
        2     1  15  15     1  15             14
        3    14  19  19    14  19             14
        4    19   5   5    19   5              1
In [171]: from collections import defaultdict
          col_counts = defaultdict(int)
          col_ix = df2.first_valid_index()
In [172]: cols = []
          for col in df2.ix[col_ix]:
              cnt = col_counts[col]
              col_counts[col] += 1
              suf = '_' + str(cnt) if cnt else ''
              cols.append(col + suf)
          cols
Out[172]:
          ['Time', 'H1', 'N2', 'Time_1', 'N2_1', 'Time Relative']
In [174]: df2.columns = cols
          df2 = df2.drop([col_ix])
In [177]: df2
Out[177]:
          Time  H1  N2 Time_1 N2_1 Time Relative
        1    3  13  13      3   13             0
        2    1  15  15      1   15            14
        3   14  19  19     14   19            14
        4   19   5   5     19    5             1
In [178]: df2.T.drop_duplicates().T
Out[178]:
          Time  H1 Time Relative
        1    3  13             0
        2    1  15            14
        3   14  19            14
        4   19   5             1 

This one will work, I am sure!

This is for longs, but you can modify it easily to work with ints.

private static long[] ConvertStringArrayToLongArray(string str)
{
    return str.Split(",".ToCharArray()).Select(x => long.Parse(x.ToString())).ToArray();
}

Whereas @jbarrueta answer is perfect, in the 2.12 version of Jackson was introduced a new long-awaited type for the @JsonTypeInfo annotation, DEDUCTION.

It is useful for the cases when you have no way to change the incoming json or must not do so. I'd still recommend to use use = JsonTypeInfo.Id.NAME, as the new way may throw an exception in complex cases when it has no way to determine which subtype to use.

Now you can simply write

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonSubTypes;
import com.fasterxml.jackson.annotation.JsonTypeInfo;

@JsonIgnoreProperties(ignoreUnknown = true)
@JsonTypeInfo(use = JsonTypeInfo.Id.DEDUCTION)
@JsonSubTypes({
    @JsonSubTypes.Type(Dog.class),
    @JsonSubTypes.Type(Cat.class) }
)
public abstract class Animal {

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

And it will produce {"name":"ruffus", "breed":"english shepherd"} and {"name":"goya", "favoriteToy":"mice"}

Once again, it's safer to use NAME if some of the fields may be not present, like breed or favoriteToy.

Try this,

for (char[] temp : box) {
    System.err.println(Arrays.toString(temp).replaceAll(",", " ").replaceAll("\\[|\\]", ""));
}

✕ is another great one that's not too thick. The HTML code is ✕, or 2715 in hex.

SMTP -> FROM SERVER:
SMTP -> FROM SERVER:
SMTP -> ERROR: EHLO not accepted from server:

that's typical of trying to connect to a SSL service with a client that's not using SSL

SMTP Error: Could not authenticate.

no suprise there having failed to start an SMTP conversation authentigation is not an option,.

phpmailer doesn't do implicit SSL (aka TLS on connect, SMTPS) Short of rewriting smtp.class.php to include support for it there it no way to do what you ask.

Use port 587 with explicit SSL (aka TLS, STARTTLS) instead.

This can be achieved in a very simple way 1. Write this in the view.

<Button HorizontalAlignment="Center" VerticalAlignment="Center" Width="50" Height="30">
<Button.Style>
        <Style TargetType="Button">
                <Setter Property="Visibility" Value="Collapsed"/>
                        <Style.Triggers>
                                <DataTrigger Binding="{Binding IsHide}" Value="True">
                                        <Setter Property="Visibility" Value="Visible"/>
                                    </DataTrigger>
                            </Style.Triggers>
            </Style>
    </Button.Style>

2. The following is the Boolean property which holds the true/ false value. The following is the code snippet. In my example this property is in UserNote class.

   public bool _isHide = false;
   
   public bool IsHide
   {
   
   get { return _isHide; }
   
   set
       {
           _isHide = value;
               OnPropertyChanged("IsHide");
       }
   } 
   

3. This is the way the IsHide property gets the value.

   userNote.IsHide = userNote.IsNoteDeleted;
   

It's browser dependent. "By default, Internet Explorer has a KeepAliveTimeout value of one minute and an additional limiting factor (ServerInfoTimeout) of two minutes. Either setting can cause Internet Explorer to reset the socket." - from IE support http://support.microsoft.com/kb/813827

Firefox is around the same value I think as well.

Usually though server timeout are set lower than browser timeouts, but at least you can control that and set it higher.

You'd rather handle the timeout though, so that way you can act upon such an event. See this thread: How to detect timeout on an AJAX (XmlHttpRequest) call in the browser?

Are you debugging on console? There are various options for debugging PHP. The most common function used for quick & dirty debugging is var_dump.

That being said and out of the way, although var_dump is awesome and a lot of people do everything with just that, there are other tools and techniques that can spice it up a bit.

Things to help out if debugging in a webpage, wrap <pre> </pre> tags around your dump statement to give you proper formatting on arrays and objects.

Ie:

<div> some html code ....
      <a href="<?php $tpl->link;?>">some link to test</a>
</div>

      dump $tpl like this:

    <pre><?php var_dump($tpl); ?></pre>

And, last but not least make sure if debugging your error handling is set to display errors. Adding this at the top of your script may be needed if you cannot access server configuration to do so.

error_reporting(E_ALL);
ini_set('display_errors', '1');

Good luck!

The iFrame attribute does not support percent in HTML5. It only supports pixels. http://www.w3schools.com/tags/att_iframe_height.asp

you can use triggers. works very well

CREATE TABLE MyTable(
ID INTEGER PRIMARY KEY,
Name TEXT,
Other STUFF,
Timestamp DATETIME);


CREATE TRIGGER insert_Timestamp_Trigger
AFTER INSERT ON MyTable
BEGIN
   UPDATE MyTable SET Timestamp =STRFTIME('%Y-%m-%d %H:%M:%f', 'NOW') WHERE id = NEW.id;
END;

CREATE TRIGGER update_Timestamp_Trigger
AFTER UPDATE On MyTable
BEGIN
   UPDATE MyTable SET Timestamp = STRFTIME('%Y-%m-%d %H:%M:%f', 'NOW') WHERE id = NEW.id;
END;

Delete the most recent commit, keeping the work you've done:

git reset --soft HEAD~1

Delete the most recent commit, destroying the work you've done:

git reset --hard HEAD~1

Use a Java 8 Stream.

myString.chars().mapToObj(i -> (char) i).collect(Collectors.toList());

Breakdown:

myString
    .chars() // Convert to an IntStream
    .mapToObj(i -> (char) i) // Convert int to char, which gets boxed to Character
    .collect(Collectors.toList()); // Collect in a List<Character>

(I have absolutely no idea why String#chars() returns an IntStream.)

You can change checkbox color using singe line of code

android:buttonTint="@color/app_color" //whatever color

Node.js supports circular dependencies.
Making use of circular dependencies instead of require('./routes')(app) cleans up a lot of code and makes each module less interdependent on its loading file:

var app = module.exports = express(); //now app.js can be required to bring app into any file

//some app/middleware setup, etc, including 
app.use(app.router);

require('./routes'); //module.exports must be defined before this line

var app = require('../app');

app.get('/', function(req, res, next) {
  res.render('index');
});

//require in some other route files...each of which requires app independently
require('./user');
require('./blog');

Example from their new generator:
Writing the route:
https://github.com/expressjs/generator/blob/master/templates/js/routes/index.js
Adding/namespacing it to the app: https://github.com/expressjs/generator/blob/master/templates/js/app.js#L24

There are still usecases for accessing app from other resources, so circular dependencies are still a valid solution.

I originally intentionally never learned how to use eval, because most people will recommend to stay away from it like the plague. However I recently discovered a use case that made me facepalm for not recognizing it sooner.

If you have cron jobs that you want to run interactively to test, you might view the contents of the file with cat, and copy and paste the cron job to run it. Unfortunately, this involves touching the mouse, which is a sin in my book.

Lets say you have a cron job at /etc/cron.d/repeatme with the contents:

*/10 * * * * root program arg1 arg2

You cant execute this as a script with all the junk in front of it, but we can use cut to get rid of all the junk, wrap it in a subshell, and execute the string with eval

eval $( cut -d ' ' -f 6- /etc/cron.d/repeatme)

The cut command only prints out the 6th field of the file, delimited by spaces. Eval then executes that command.

I used a cron job here as an example, but the concept is to format text from stdout, and then evaluate that text.

The use of eval in this case is not insecure, because we know exactly what we will be evaluating before hand.

SingleOrDefault method throws an Exception if there is more than one element in the sequence.

Apparently, your query in GetCustomer is finding more than one match. So you will either need to refine your query or, most likely, check your data to see why you're getting multiple results for a given customer number.

Try this:

<input type="number" max="???" min="???" step="0.5" id="myInput"/>

$("#myInput").attr({
   "max" : 10,
   "min" : 2
});

Note:This will set max and min value only to single input

Make file executable:

chmod +x file

Find location of perl:

which perl

This should return something like

/bin/perl sometimes /usr/local/bin

Then in the first line of your script add:

#!"path"/perl with path from above e.g.

#!/bin/perl

Then you can execute the file

./file

There may be some issues with the PATH, so you may want to change that as well ...

Actually it has been worked but

just try this.

take the value /\s/g into a string variable like

String a = /\s/g;

str = str.replaceAll(a,"X");

It is possible to pass arrays to functions, and there are no special requirements for dealing with them. Are you sure that the array you are passing to to your function actually has an element at [0]?

class key
{
    int m_value;
public:
    bool operator<(const key& src)const
    {
        return (this->m_value < src.m_value);
    }

};
int main()
{
    key key1;
    key key2;
    map<key,int> mymap;
    mymap.insert(pair<key,int>(key1,100));
    mymap.insert(pair<key,int>(key2,200));
    map<key,int>::iterator iter=mymap.begin();
    for(;iter!=mymap.end();++iter)
    {
        cout<<iter->second<<endl;
    }


}

If you use RAC then you need to use GV$* views instead V$*. Try to find your session by

select * from gv$session where username = 'test';

and then you can kill the session by

alter system kill session 'sid, serial#, @inst_id' immediate;

Assuming you are trying to pass the command line arguments as well.

import sys
import myModule


def main():
    # this will just pass all of the system arguments as is
    myModule.main(*sys.argv)

    # all the argv but the script name
    myModule.main(*sys.argv[1:])

There is no official datepicker for bootstrap; as such, you should explicitly state which one you're using.

If you're using eternicode/bootstrap-datepicker, there's a startDate option. As discussed directly under the Options section in the README:

All options that take a "Date" can handle a Date object; a String formatted according to the given format; or a timedelta relative to today, eg '-1d', '+6m +1y', etc, where valid units are 'd' (day), 'w' (week), 'm' (month), and 'y' (year).

So you would do:

$('#datepicker').datepicker({
    startDate: '+1d'
})

fgets would work for you. here is very good documentation on this :-
http://www.cplusplus.com/reference/cstdio/fgets/

If you don't want to use fgets, following method will work for you :-

int readline(FILE *f, char *buffer, size_t len)
{
   char c; 
   int i;

   memset(buffer, 0, len);

   for (i = 0; i < len; i++)
   {   
      int c = fgetc(f); 

      if (!feof(f)) 
      {   
         if (c == '\r')
            buffer[i] = 0;
         else if (c == '\n')
         {   
            buffer[i] = 0;

            return i+1;
         }   
         else
            buffer[i] = c; 
      }   
      else
      {   
         //fprintf(stderr, "read_line(): recv returned %d\n", c);
         return -1; 
      }   
   }   

   return -1; 
}

The problem was that I had some other normal error messages in my project, and apparently after I fixed those and when I cleaned and built my project AGAIN, then all .dlls succeeded.

Make sure you don't have any other error messages in your project and if you do, fix those first!

Alternatively, consider using a document databases (such as MongoDB) which natively support rich data structures and nesting.

The files managed by git are shown by git ls-files. Check out its manual page.

Martin Joiner's problem is caused by a misunderstanding of the <caption> tag.

The <caption> tag defines a table caption.

The <caption> tag must be the first child of the <table> tag.

You can specify only one caption per table.

Also, note that the scope attribute should be placed on a <th> element and not on a <tr> element.

The proper way to write a multi-header multi-tbody table would be something like this :

<table id="dinner_table">_x000D_
    <caption>This is the only correct place to put a caption.</caption>_x000D_
    <tbody>_x000D_
        <tr class="header">_x000D_
            <th colspan="2" scope="col">First Half of Table (British Dinner)</th>_x000D_
        </tr>_x000D_
        <tr>_x000D_
            <th scope="row">1</th>_x000D_

I meet this error when integrate modal bootstrap in angular.

This is my solution to solve this issue.

I share for whom concern.

First step you need install jquery and bootstrap by npm command.

Second you need add declare var $ : any; in component

And use can use $('#myModal').modal('hide'); on onSave() method

Demo https://stackblitz.com/edit/angular-model-bootstrap-close?file=src/app/app.component.ts

This works for me:

select date_format(date(starttime),'%Y-%m-%d') from data
where date(starttime) >= date '2012-11-02';

Note the format string '%Y-%m-%d' and the format of the input date.

I the following error message when faced this same problem:

The type of one of the expressions in the join clause is incorrect. Type inference failed in the call to 'GroupJoin'.

Solved when I used the same property name, it worked.

(...)

join enderecoST in db.PessoaEnderecos on 
    new 
      {  
         CD_PESSOA          = nf.CD_PESSOA_ST, 
         CD_ENDERECO_PESSOA = nf.CD_ENDERECO_PESSOA_ST 
      } equals 
    new 
    { 
         enderecoST.CD_PESSOA, 
         enderecoST.CD_ENDERECO_PESSOA 
    } into eST

(...)

Be careful that this will create an "alternate reality" for people who have already fetch/pulled/cloned from the remote repository. But in fact, it's quite simple:

git reset HEAD^ # remove commit locally
git push origin +HEAD # force-push the new HEAD commit

If you want to still have it in your local repository and only remove it from the remote, then you can use:

git push origin +HEAD^:<name of your branch, most likely 'master'>

NSString's method is lowercaseString (0 arguments), not lowercaseString: (1 argument).

I ran into this same issue. Someone had logged onto my computer and used their TFS credentials. I'm running VS2012, Windows 7, and the network admins have Credential Manager disabled.

Run this command from a command window with the same user your running visual studio as.

rundll32.exe keymgr.dll,KRShowKeyMgr

You'll see a popup with all your stored credentials. Remove the one for your TFS server.

Note: You will need to restart visual studio because it caches the tfs credentials.

This will definitely work. Orange outline won't show up anymore.. Common for all tags:

*:focus {
    outline: none;
   }

Specific to some tag, ex: input tag

input:focus{
   outline:none;
  }

Others have mentioned the architecture differences (little - big endian).

I read the problem that since the memory for the variables is shared, then by writing to one, the others change and, depending on their type, the value could be meaningless.

eg. union{ float f; int i; } x;

Writing to x.i would be meaningless if you then read from x.f - unless that is what you intended in order to look at the sign, exponent or mantissa components of the float.

I think there is also an issue of alignment: If some variables must be word aligned then you might not get the expected result.

eg. union{ char c[4]; int i; } x;

If, hypothetically, on some machine a char had to be word aligned then c[0] and c[1] would share storage with i but not c[2] and c[3].

You're correct that this is really painful to hand out to others, but if you have to, this is how you do it.

1. Just extract the .ocx file from the .cab file (it is similar to a zip)
2. Copy to the system folder (c:\windows\sysWOW64 for 64 bit systems and c:\windows\system32 for 32 bit)
3. Use regsvr32 through the command prompt to register the file (e.g. "regsvr32 c:\windows\sysWOW64\mscomct2.ocx")

I came across this thread because I was looking to build an absolute URI for a success page. request.build_absolute_uri() gave me a URI for my current view but to get the URI for my success view I used the following....

request.build_absolute_uri(reverse('success_view_name'))

If you are using <ng-content> with *ngIf you are bound to fall into this loop.

Only way out I found was to change *ngIf to display:none functionality

I came across this question and inspired by other contributors. I need to append some content to a file once per line. Here is what I did.

class Doh {
   def ln = System.getProperty('line.separator')
   File file //assume it's initialized 

   void append(String content) {
       file << "$content$ln"
   }
}

Pretty neat I think :)

Building on the answers above using the indeterminate state, I've come up with a little bit that handles individual checkboxes and makes them tri-state.

MVC razor uses 2 inputs per checkbox anyway (the checkbox and a hidden with the same name to always force a value in the submit). MVC uses things like "true" as the checkbox value and "false" as the hidden of the same name; makes it amenable to boolean use in api calls. This snippet uses an third hidden to persist the last request values across submits.

Checkboxes initialized with the below will start indeterminate. Checking once turns on the checkbox. Checking twice turns off the checkbox (returning the hidden value of the same name). Checking a third time returns it to indeterminate (and clears out the hidden so a submit will produce a blank).

The page also populates another hidden (e.g. triBox2Orig) with whatever value was on the query string to start, so the 3 states can be initialized and persisted between submits.

$(document).ready(function () {
    var initCheckbox = function (chkBox)
    {
        var hidden = $('[name="' + $(chkBox).prop("name") + '"][type="hidden"]');
        var hiddenOrig = $('[name="' + $(chkBox).prop("name") + 'Orig"][type="hidden"]').prop("value");
        hidden.prop("origValue", hidden.prop("value"));
        if (!chkBox.prop("checked") && !hiddenOrig) chkBox.prop("indeterminate", true);
        if (chkBox.prop("indeterminate")) hidden.prop("value", null);
        chkBox.change(checkBoxToggleFun);
    }

    var checkBoxToggleFun = function ()
    {
        var isChecked = $(this).prop('checked');
        var hidden = $('[name="' + $(this).prop("name") + '"][type="hidden"]');
        var thirdState = isChecked && hidden.prop("value") === hidden.prop("origValue");
        if (thirdState) {   // on 3rd click of a checkbox, set it back to indeterminate
            $(this).prop("indeterminate", true);
            $(this).prop('checked', false);
        }
        hidden.prop("value", thirdState ? null : hidden.prop("origValue"));
    };

    var chkBox = $('#triBox1');
    initCheckbox(chkBox);

    chkBox = $('#triBox2');
    initCheckbox(chkBox);
});

• What are the downsides of using adhoc/on-the-fly SQL statements and what would you do instead?

This area can have a huge impact on performance and security of the db. Get this wrong, and you could end up in a world of pain.

• In what situations would you use adhoc/on-the-fly SQL statements?

Because there is always an exception to the rule :)

In the client side handle the click event of the button, use the ClientID property to get he id of the button:

$(document).ready(function() {
$("#<%=myButton.ClientID %>,#<%=muSecondButton.ClientID%>").click(

    function() {
     $.get("/myPage.aspx",{id:$(this).attr('id')},function(data) {
       // do something with the data
     return false;
     }
    });
 });

In your page on the server:

protected void Page_Load(object sender,EventArgs e) {
 // check if it is an ajax request
 if (Request.Headers["X-Requested-With"] == "XMLHttpRequest") {
  if (Request.QueryString["id"]==myButton.ClientID) {
    // call the click event handler of the myButton here
    Response.End();
  }
  if (Request.QueryString["id"]==mySecondButton.ClientID) {
    // call the click event handler of the mySecondButton here
    Response.End();
  }
 }
}

append strings with add function

str1 = "Hello"
str2 = " World"
str3 = str.__add__(str2)
print(str3)

Output

You could define a mapping of air pressure to servo angle, for example:

def calc_angle(pressure, min_p=1000, max_p=1200):     return 360 * ((pressure - min_p) / float(max_p - min_p))  angle = calc_angle(pressure) 

This will linearly convert pressure values between min_p and max_p to angles between 0 and 360 (you could include min_a and max_a to constrain the angle, too).

To pick a data structure, I wouldn't use a list but you could look up values in a dictionary:

d = {1000:0, 1001: 1.8, ...}  angle = d[pressure] 

but this would be rather time-consuming to type out!

If you're running with jQuery you can use the datepicker UI library's parseDate function to convert your string to a date:

var d = $.datepicker.parseDate("DD, MM dd, yy",  "Sunday, February 28, 2010");

and then follow it up with the formatDate method to get it to the string format you want

var datestrInNewFormat = $.datepicker.formatDate( "mm/dd/yy", d);

If you're not running with jQuery of course its probably not the best plan given you'd need jQuery core as well as the datepicker UI module... best to go with the suggestion from Segfault above to use date.js.

I would have put this in a comment on the accepted answer, since that's where it belongs, but I can't. So, just in case anyone gets unreliable results, this could be why.

Be careful of the accepted answer, it fails if the time_point is before the epoch.

This line of code:

std::size_t fractional_seconds = ms.count() % 1000;

will yield unexpected values if ms.count() is negative (since size_t is not meant to hold negative values).

When using this approach you have to make sure that none of your values contains something that would be illegal XML – user1151923

I always use the XML method. Make sure you use VALID XML. I have two functions to convert between valid XML and Text. (I tend to strip out the carriage returns as I don't usually need them.

There are both zip and unzip executables (as well as a boat load of other useful applications) in the UnxUtils package available on SourceForge (http://sourceforge.net/projects/unxutils). Copy them to a location in your PATH, such as 'c:\windows', and you will be able to include them in your scripts.

This is not the perfect solution (or the one you asked for) but a decent work-a-round.

There is a JDK dropdown in "job name" -> Configure in Jenkins web ui. It will list all JDKs available in Jenkins configuration.

Since it is your files in your app bundle, I think you can use pathForResource:ofType: to get the full pathname of your file.

Here is an example:

NSString* filePath = [[NSBundle mainBundle] pathForResource:@"your_file_name"

Haven't tried it myself, but I think

http://www.playframework.org/

has a lot of potential...

coming from php and classic asp, it's the first java web framework that sounds promising to me....

Edit by original question asker - 2011-06-09

Just wanted to provide an update.

I went with Play and it was exactly what I asked for. It requires very little configuration, and just works out of the box. It is unusual in that it eschews some common Java best-practices in favor of keeping things as simple as possible.

In particular, it makes heavy use of static methods, and even does some introspection on the names of variables passed to methods, something not supported by the Java reflection API.

Play's attitude is that its first goal is being a useful web framework, and sticking to common Java best-practices and idioms is secondary to that. This approach makes sense to me, but Java purists may not like it, and would be better-off with Apache Wicket.

In summary, if you want to build a web-app with convenience and simplicity comparable to a framework like Ruby on Rails, but in Java and with the benefit of Java's tooling (eg. Eclipse), then Play Framework is a great choice.

Overview

• const guarantees that a program does not change an object’s value. However, const does not guarantee which type of initialization the object undergoes.

  Consider:

  const int mx = numeric_limits<int>::max();  // OK: runtime initialization
  

  The function max() merely returns a literal value. However, because the initializer is a function call, mx undergoes runtime initialization. Therefore, you cannot use it as a constant expression:

  int arr[mx];  // error: “constant expression required”
  

• constexpr is a new C++11 keyword that rids you of the need to create macros and hardcoded literals. It also guarantees, under certain conditions, that objects undergo static initialization. It controls the evaluation time of an expression. By enforcing compile-time evaluation of its expression, constexpr lets you define true constant expressions that are crucial for time-critical applications, system programming, templates, and generally speaking, in any code that relies on compile-time constants.

Constant-expression functions

A constant-expression function is a function declared constexpr. Its body must be non-virtual and consist of a single return statement only, apart from typedefs and static asserts. Its arguments and return value must have literal types. It can be used with non-constant-expression arguments, but when that is done the result is not a constant expression.

A constant-expression function is meant to replace macros and hardcoded literals without sacrificing performance or type safety.

constexpr int max() { return INT_MAX; }           // OK
constexpr long long_max() { return 2147483647; }  // OK
constexpr bool get_val()
{
    bool res = false;
    return res;
}  // error: body is not just a return statement

constexpr int square(int x)
{ return x * x; }  // OK: compile-time evaluation only if x is a constant expression
const int res = square(5);  // OK: compile-time evaluation of square(5)
int y = getval();
int n = square(y);          // OK: runtime evaluation of square(y)

Constant-expression objects

A constant-expression object is an object declared constexpr. It must be initialized with a constant expression or an rvalue constructed by a constant-expression constructor with constant-expression arguments.

A constant-expression object behaves as if it was declared const, except that it requires initialization before use and its initializer must be a constant expression. Consequently, a constant-expression object can always be used as part of another constant expression.

struct S
{
    constexpr int two();      // constant-expression function
private:
    static constexpr int sz;  // constant-expression object
};
constexpr int S::sz = 256;
enum DataPacket
{
    Small = S::two(),  // error: S::two() called before it was defined
    Big = 1024
};
constexpr int S::two() { return sz*2; }
constexpr S s;
int arr[s.two()];  // OK: s.two() called after its definition

Constant-expression constructors

A constant-expression constructor is a constructor declared constexpr. It can have a member initialization list but its body must be empty, apart from typedefs and static asserts. Its arguments must have literal types.

A constant-expression constructor allows the compiler to initialize the object at compile-time, provided that the constructor’s arguments are all constant expressions.

struct complex
{
    // constant-expression constructor
    constexpr complex(double r, double i) : re(r), im(i) { }  // OK: empty body
    // constant-expression functions
    constexpr double real() { return re; }
    constexpr double imag() { return im; }
private:
    double re;
    double im;
};
constexpr complex COMP(0.0, 1.0);         // creates a literal complex
double x = 1.0;
constexpr complex cx1(x, 0);              // error: x is not a constant expression
const complex cx2(x, 1);                  // OK: runtime initialization
constexpr double xx = COMP.real();        // OK: compile-time initialization
constexpr double imaglval = COMP.imag();  // OK: compile-time initialization
complex cx3(2, 4.6);                      // OK: runtime initialization

Tips from the book Effective Modern C++ by Scott Meyers about constexpr:

• constexpr objects are const and are initialized with values known during compilation;
• constexpr functions produce compile-time results when called with arguments whose values are known during compilation;
• constexpr objects and functions may be used in a wider range of contexts than non-constexpr objects and functions;
• constexpr is part of an object’s or function’s interface.

I just learned something new thanks to Artiso. I gave each module a name in the properties box. These names were also what I declared in the module. When I tried to call my second module, I kept getting an error: Compile error: Expected variable or procedure, not module

After reading Artiso's comment above about not having the same names, I renamed my second module, called it from the first, and problem solved. Interesting stuff! Thanks for the info Artiso!

In case my experience is unclear:

Module Name: AllFSGroupsCY Public Sub AllFSGroupsCY()

Module Name: AllFSGroupsPY Public Sub AllFSGroupsPY()

From AllFSGroupsCY()

Public Sub FSGroupsCY()

    AllFSGroupsPY 'will error each time until the properties name is changed

End Sub

Do a cross-domain AJAX call

Your web-service must support method injection in order to do JSONP.

Your code seems fine and it should work if your web services and your web application hosted in the same domain.

When you do a $.ajax with dataType: 'jsonp' meaning that jQuery is actually adding a new parameter to the query URL.

For instance, if your URL is http://10.211.2.219:8080/SampleWebService/sample.do then jQuery will add ?callback={some_random_dynamically_generated_method}.

This method is more kind of a proxy actually attached in window object. This is nothing specific but does look something like this:

window.some_random_dynamically_generated_method = function(actualJsonpData) {
    //here actually has reference to the success function mentioned with $.ajax
    //so it just calls the success method like this: 
    successCallback(actualJsonData);
}

Check the following for more information

Make cross-domain ajax JSONP request with jQuery

You have to use UPDATE instead of INSERT:

• UPDATE Syntax

For Example:

UPDATE table1 SET col_a='k1', col_b='foo' WHERE key_col='1';
UPDATE table1 SET col_a='k2', col_b='bar' WHERE key_col='2';

tl;dr

myUtilDate.toInstant()                          // Convert from legacy class to modern. `Instant` is a point on the timeline in UTC.
          .atZone(                              // Adjust from UTC to a particular time zone to determine date. Renders a `ZonedDateTime` object. 
              ZoneId.of( "America/Montreal" )   // Better to specify desired/expected zone explicitly than rely implicitly on the JVM’s current default time zone.
          )                                     // Returns a `ZonedDateTime` object.
          .getMonthValue()                      // Extract a month number. Returns a `int` number.

java.time Details

The Answer by Ortomala Lokni for using java.time is correct. And you should be using java.time as it is a gigantic improvement over the old java.util.Date/.Calendar classes. See the Oracle Tutorial on java.time.

I'll add some code showing how to use java.time without regard to java.util.Date, for when you are starting out with fresh code.

Using java.time in a nutshell… An Instant is a moment on the timeline in UTC. Apply a time zone (ZoneId) to get a ZonedDateTime.

The Month class is a sophisticated enum to represent a month in general. That enum has handy methods such as getting a localized name. And rest assured that the month number in java.time is a sane one, 1-12, not the zero-based nonsense (0-11) found in java.util.Date/.Calendar.

To get the current date-time, time zone is crucial. At any moment the date is not the same around the world. Therefore the month is not the same around the world if near the ending/beginning of the month.

ZoneId zoneId = ZoneId.of( "America/Montreal" );  // Or 'ZoneOffset.UTC'.
ZonedDateTime now = ZonedDateTime.now( zoneId );
Month month = now.getMonth(); 
int monthNumber = month.getValue(); // Answer to the Question.
String monthName = month.getDisplayName( TextStyle.FULL , Locale.CANADA_FRENCH );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

But i would not recommend you hosting from cdn for the following reasons

1. Although your chance of hit rate is good in case of Google CDN compared to others but it's still abysmally low.(any cdn not just google).
2. Loading via cdn you will have 3 requests one for jQuery.js, one for jQueryUI.js and one for your code. You might as will compress it on your local and load it as one single resource.

Mono Develop is what you want, if you have used visual studio you should find it simple enough to get started.

If I recall correctly you should be able to install with sudo apt-get install monodevelop

1)Go to configure build path . 2)Remove unbound JRE library . 3)Add library --> JRE System library .

Then project compile and done ..

Suffered from exact issue. Problem was because of NameValueSectionHandler in .config file. You should use AppSettingsSection instead:

<configuration>

 <configSections>
    <section  name="DEV" type="System.Configuration.AppSettingsSection" />
    <section  name="TEST" type="System.Configuration.AppSettingsSection" />
 </configSections>

 <TEST>
    <add key="key" value="value1" />
 </TEST>

 <DEV>
    <add key="key" value="value2" />
 </DEV>

</configuration>

then in C# code:

AppSettingsSection section = (AppSettingsSection)ConfigurationManager.GetSection("TEST");

btw NameValueSectionHandler is not supported any more in 2.0.

The database is a MySQL database, not a phpMyAdmin database. phpMyAdmin is only PHP code that connects to the DB.

mysql_connect('localhost', 'username', 'password') or die (mysql_error());
mysql_select_database('db_name') or die (mysql_error());

// now you are connected

Yes, it is possible to merge .NET executables with libraries. There are multiple tools available to get the job done:

• ILMerge is a utility that can be used to merge multiple .NET assemblies into a single assembly.
• Mono mkbundle, packages an exe and all assemblies with libmono into a single binary package.
• IL-Repack is a FLOSS alterantive to ILMerge, with some additional features.

In addition this can be combined with the Mono Linker, which does remove unused code and therefor makes the resulting assembly smaller.

Another possibility is to use .NETZ, which does not only allow compressing of an assembly, but also can pack the dlls straight into the exe. The difference to the above mentioned solutions is that .NETZ does not merge them, they stay separate assemblies but are packed into one package.

.NETZ is a open source tool that compresses and packs the Microsoft .NET Framework executable (EXE, DLL) files in order to make them smaller.

Since Python 3.5, subprocess.run() is recommended over subprocess.check_output():

>>> subprocess.run(['cat','/tmp/text.txt'], stdout=subprocess.PIPE).stdout
b'First line\nSecond line\n'

Since Python 3.7, instead of the above, you can use capture_output=true parameter to capture stdout and stderr:

>>> subprocess.run(['cat','/tmp/text.txt'], capture_output=True).stdout
b'First line\nSecond line\n'

Also, you may want to use universal_newlines=True or its equivalent since Python 3.7 text=True to work with text instead of binary:

>>> stdout = subprocess.run(['cat', '/tmp/text.txt'], capture_output=True, text=True).stdout
>>> print(stdout)
First line
Second line

See subprocess.run() documentation for more information.

%run YourNotebookfile.ipynb is working fine;

if you want to import a specific module then just add the import command after the ipynb i.e YourNotebookfile.ipynb having def Add()

then you can just use it

%run YourNotebookfile.ipynb import Add

You are not the first one to think about a "revision number" in Git, but 'wc' is quite dangerous, since commit can be erased or squashed, and the history revisited.

The "revision number" was especially important for Subversion since it was needed in case of merge (SVN1.5 and 1.6 have improved on that front).

You could end up with a pre-commit hook which would include a revision number in the comment, with an algorithm not involving looking up the all history of a branch to determine the correct number.

Bazaar actually came up with such an algorithm , and it may be a good starting point for what you want to do.

(As Bombe's answer points out, Git has actually an algorithm of its own, based on the latest tag, plus the number of commits, plus a bit of an SHA-1 key). You should see (and upvote) his answer if it works for you.

To illustrate Aaron's idea, you can also append the Git commit hash into an application’s "info" file you are distributing with your application.

That way, the about box would look like:

The applicative number is part of the commit, but the 'application’s "info" file' is generated during the packaging process, effectively linking an applicative build number to a technical revision id.

awk '{a=match($0, $3); print substr($0,a)}'

First you find the position of the start of the third column. With substr you will print the whole line ($0) starting at the position(in this case a) to the end of the line.

Simple printf() function from O'Reilly's Python Cookbook.

import sys
def printf(format, *args):
    sys.stdout.write(format % args)

Example output:

i = 7
pi = 3.14159265359
printf("hi there, i=%d, pi=%.2f\n", i, pi)
# hi there, i=7, pi=3.14

The REAL REAL answer is: For API 21 and higher:

No java code needed. You can set android:nestedScrollingEnabled="false" in xml:

<android.support.v7.widget.RecyclerView
     android:id="@+id/recycler"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:clipToPadding="true"
     android:nestedScrollingEnabled="false"
     tools:listitem="@layout/adapter_favorite_place">

Do you really need to "build" it from javascript or can you simply return the built HTML from PHP and insert it into the DOM?

1. Send AJAX request to php script
2. PHP script processes request and builds table
3. PHP script sends response back to JS in form of encoded HTML
4. JS takes response and inserts it into the DOM

Another way of monitoring a child-process is to create a worker thread that will :

1. call CreateProcess()
2. call WaitForSingleObject() // the worker thread will now wait till the child-process finishes execution. it's possible to grab the return code (from the main() function) too.

This is the correct way to make a pure call. No CSS.

<div style='background:url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABwAAAAFCAYAAABW1IzHAAAAHklEQVQokWNgGPaAkZHxPyMj439sYrSQo51PBgsAALa0ECF30JSdAAAAAElFTkSuQmCC)repeat-x center;'></div>

Native way to get the mimetype:

For PHP < 5.3 use mime_content_type()
For PHP >= 5.3 use finfo_open() or mime_content_type()

Alternatives to get the MimeType are exif_imagetype and getimagesize, but these rely on having the appropriate libs installed. In addition, they will likely just return image mimetypes, instead of the whole list given in magic.mime.

While mime_content_type is available from PHP 4.3 and is part of the FileInfo extension (which is enabled by default since PHP 5.3, except for Windows platforms, where it must be enabled manually, for details see here).

If you don't want to bother about what is available on your system, just wrap all four functions into a proxy method that delegates the function call to whatever is available, e.g.

function getMimeType($filename)
{
    $mimetype = false;
    if(function_exists('finfo_open')) {
        // open with FileInfo
    } elseif(function_exists('getimagesize')) {
        // open with GD
    } elseif(function_exists('exif_imagetype')) {
       // open with EXIF
    } elseif(function_exists('mime_content_type')) {
       $mimetype = mime_content_type($filename);
    }
    return $mimetype;
}

Besides being easier to read (for many people), list comprehensions win the speed race, too:

$ python2.6 -m timeit '[x.lower() for x in ["A","B","C"]]'
1000000 loops, best of 3: 1.03 usec per loop
$ python2.6 -m timeit '[x.upper() for x in ["a","b","c"]]'
1000000 loops, best of 3: 1.04 usec per loop

$ python2.6 -m timeit 'map(str.lower,["A","B","C"])'
1000000 loops, best of 3: 1.44 usec per loop
$ python2.6 -m timeit 'map(str.upper,["a","b","c"])'
1000000 loops, best of 3: 1.44 usec per loop

$ python2.6 -m timeit 'map(lambda x:x.lower(),["A","B","C"])'
1000000 loops, best of 3: 1.87 usec per loop
$ python2.6 -m timeit 'map(lambda x:x.upper(),["a","b","c"])'
1000000 loops, best of 3: 1.87 usec per loop

In C shell - The ampersand is after the greater-than symbol

make >& filename

Assuming you're using a std::ofstream to write to file, the following snippet will write a std::string to file in human readable form:

std::ofstream file("filename");
std::string my_string = "Hello text in file\n";
file << my_string;

When this error occurred to me was because Pods folder was in iCloud and had no local copy on my computer. Go to your project's folder in Finder and check if there is iCloud's symbol in any of the folders inside it!

Well, your syntax isn't really Python to begin with.

Iterations in Python are over he contents of containers (well, technically it's over iterators), with a syntax for item in container. In this case, the container is the cars list, but you want to skip the first and last elements, so that means cars[1:-1] (python lists are zero-based, negative numbers count from the end, and : is slicing syntax.

So you want

for c in cars[1:-1]:
    do something with c

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.1'

defaultConfig {
    applicationId ""
    minSdkVersion 14
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.code.gson:gson:2.3.1'
compile 'com.android.support:recyclerview-v7:23.0.0'
compile 'com.android.support:appcompat-v7:23.0.1'
}

Adding only android-support-v7-appcompat.jar to library dependencies is not enough, you have also to import in your project the module that you can find in your SDK at the path \android-sdk\extras\android\support\v7\appcompatand after that add module dependencies configuring the project structure in this way

otherwise are included only the class files of support library and the app is not able to load the other resources causing the error.

In addition as reVerse suggested replace this

public CustomActionBarDrawerToggle(Activity mActivity,
                                           DrawerLayout mDrawerLayout) {
            super(mActivity, mDrawerLayout,new Toolbar(MyActivity.this) ,
                    R.string.ns_menu_open, R.string.ns_menu_close);
        }

with

public CustomActionBarDrawerToggle(Activity mActivity,
                                           DrawerLayout mDrawerLayout) {
            super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);
        }

The selected answer posted here solved one problem, but another is that you'll have to change the app pool to use .Net 2.0.

"SharePoint 2010 uses .NET Framework 3.5, not 4.0. The SharePoint 2010 app pools should be configured as .NET Framework 2.0 using the Integrated Pipeline Mode."
