Try to use this:

using (var handler = new HttpClientHandler() { CookieContainer = new CookieContainer() })
{
    using (var client = new HttpClient(handler) { BaseAddress = new Uri("site.com") })
    {
        //add parameters on request
        var body = new List<KeyValuePair<string, string>>
        {
            new KeyValuePair<string, string>("test", "test"),
            new KeyValuePair<string, string>("test1", "test1")
        };

        HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, "site.com");

        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded; charset=UTF-8"));
        client.DefaultRequestHeaders.Add("Upgrade-Insecure-Requests", "1");
        client.DefaultRequestHeaders.Add("X-Requested-With", "XMLHttpRequest");
        client.DefaultRequestHeaders.Add("X-MicrosoftAjax", "Delta=true");
        //client.DefaultRequestHeaders.Add("Accept", "*/*");

        client.Timeout = TimeSpan.FromMilliseconds(10000);

        var res = await client.PostAsync("", new FormUrlEncodedContent(body));

        if (res.IsSuccessStatusCode)
        {
            var exec = await res.Content.ReadAsStringAsync();
            Console.WriteLine(exec);
        }                    
    }
}

What are disadvantages of the following solution? Seems to be faster and shorter.

var options = {
    set0: ['Option 1','Option 2'],
    set1: ['First Option','Second Option','Third Option']
};

var list = "<li>" + options.set0.join("</li><li>") + "</li>";
document.getElementById("list").innerHTML = list;

The ALL_CAPS is taken from the C and C++ way of working I believe. This article here explains how the style differences came about.

In the new IDE's such as Visual Studio it is easy to identify the types, scope and if they are constant so it is not strictly necessary.

The FxCop and Microsoft StyleCop software will help give you guidelines and check your code so everyone works the same way.

If you're interested in generalizing to different architectures, you could also run the command above and substitute uname -m in with backticks like so:

wget http://repo.continuum.io/miniconda/Miniconda3-latest-Linux-`uname -m`.sh

https://www.postgresql.org/docs/8.4/functions-formatting.html

SELECT to_char(date_field, 'DD/MM/YYYY')
FROM table

You could just do:

Serial.println("\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n");

or if you want:

for (int i=0; i<100; i++) {
   Serial.print("\n");
}

for /l %%a in (254, -1, 1) do ( 
    for /l %%b in (1, 1, 254) do (
        for %%c in (20, 168) do (
            for %%e in (172, 192) do (
                ping /n 1 %%e.%%c.%%b.%%a>>ping.txt
            )
        )
    )

Views

They evaluate the data in the tables underlying the view definition at the time the view is queried. It is a logical view of your tables, with no data stored anywhere else.

The upside of a view is that it will always return the latest data to you. The downside of a view is that its performance depends on how good a select statement the view is based on. If the select statement used by the view joins many tables, or uses joins based on non-indexed columns, the view could perform poorly.

Materialized views

They are similar to regular views, in that they are a logical view of your data (based on a select statement), however, the underlying query result set has been saved to a table. The upside of this is that when you query a materialized view, you are querying a table, which may also be indexed.

In addition, because all the joins have been resolved at materialized view refresh time, you pay the price of the join once (or as often as you refresh your materialized view), rather than each time you select from the materialized view. In addition, with query rewrite enabled, Oracle can optimize a query that selects from the source of your materialized view in such a way that it instead reads from your materialized view. In situations where you create materialized views as forms of aggregate tables, or as copies of frequently executed queries, this can greatly speed up the response time of your end user application. The downside though is that the data you get back from the materialized view is only as up to date as the last time the materialized view has been refreshed.

Materialized views can be set to refresh manually, on a set schedule, or based on the database detecting a change in data from one of the underlying tables. Materialized views can be incrementally updated by combining them with materialized view logs, which act as change data capture sources on the underlying tables.

Materialized views are most often used in data warehousing / business intelligence applications where querying large fact tables with thousands of millions of rows would result in query response times that resulted in an unusable application.

Materialized views also help to guarantee a consistent moment in time, similar to snapshot isolation.

GO isn't a keyword in SQL Server; it's a batch separator. GO ends a batch of statements. This is especially useful when you are using something like SQLCMD. Imagine you are entering in SQL statements on the command line. You don't necessarily want the thing to execute every time you end a statement, so SQL Server does nothing until you enter "GO".

Likewise, before your batch starts, you often need to have some objects visible. For example, let's say you are creating a database and then querying it. You can't write:

CREATE DATABASE foo;
USE foo;
CREATE TABLE bar;

because foo does not exist for the batch which does the CREATE TABLE. You'd need to do this:

CREATE DATABASE foo;
GO
USE foo;
CREATE TABLE bar;

Disabled is a Boolean Attribute of the select element as stated by WHATWG, that means the RIGHT WAY TO DISABLE with jQuery would be

jQuery("#selectId").attr('disabled',true);

This would make this HTML

<select id="selectId" name="gender" disabled="disabled">
    <option value="-1">--Select a Gender--</option>
    <option value="0">Male</option>
    <option value="1">Female</option>
</select>

This works for both XHTML and HTML (W3School reference)

Yet it also can be done using it as property

jQuery("#selectId").prop('disabled', 'disabled');

getting

<select id="selectId" name="gender" disabled>

Which only works for HTML and not XTML

NOTE: A disabled element will not be submitted with the form as answered in this question: The disabled form element is not submitted

NOTE2: A disabled element may be greyed out.

NOTE3:

A form control that is disabled must prevent any click events that are queued on the user interaction task source from being dispatched on the element.

TL;DR

<script>
    var update_pizza = function () {
        if ($("#pizza").is(":checked")) {
            $('#pizza_kind').attr('disabled', false);
        } else {
            $('#pizza_kind').attr('disabled', true);
        }
    };
    $(update_pizza);
    $("#pizza").change(update_pizza);
</script>

Had issues using the code in the answer provided by @haynar above (wouldn't play on Chrome), and it seems that one of the more modern ways to ensure it plays is to use the video tag

Example:

<video controls="controls" width="800" height="600" 
       name="Video Name" src="http://www.myserver.com/myvideo.mov"></video>

This worked like a champ for my .mov file (generated from Keynote) in both Safari and Chrome, and is listed as supported in most modern browsers (The video tag is supported in Internet Explorer 9+, Firefox, Opera, Chrome, and Safari.)

Note: Will work in IE / etc.. if you use MP4 (Mov is not officially supported by those guys)

Firstly, I highly recommend you do your CSS styling in an external CSS file, rather than doing it inline. It's much easier to maintain and can be more reusable using classes.

Working off Alex's answer (& Garret's clearfix) of "adding an element at the end with clear: both", you can do it like so:

    <div id='outerdiv' style='border: 1px solid black; background-color: black;'>
        <div style='width: 300px; border: red 1px dashed; float: left;'>
            <p>xxxxxxxxxxxxxxxxxxxxxxxxxxxxx</p>
        </div>

        <div style='width: 300px; border: red 1px dashed; float: right;'>
            <p>zzzzzzzzzzzzzzzzzzzzzzzzzzzzz</p>
        </div>
        <div style='clear:both;'></div>
    </div>

This works (but as you can see inline CSS isn't so pretty).

Directly from var/www/html

mysql -u username -p database_name < /path/to/file.sql

From within mysql:

mysql> use db_name;
mysql> source backup-file.sql

This solution is very similar to that provided by @gdw2 , only that the string formatting is correctly done to match what you asked for - "Should be as compact as possible"

>>> import datetime
>>> a = datetime.datetime.now()
>>> "%s:%s.%s" % (a.minute, a.second, str(a.microsecond)[:2])
'31:45.57'

This answer says to use

mapfile -t myArray < file.txt

I made a shim for mapfile if you want to use mapfile on bash < 4.x for whatever reason. It uses the existing mapfile command if you are on bash >= 4.x

Currently, only options -d and -t work. But that should be enough for that command above. I've only tested on macOS. On macOS Sierra 10.12.6, the system bash is 3.2.57(1)-release. So the shim can come in handy. You can also just update your bash with homebrew, build bash yourself, etc.

It uses this technique to set variables up one call stack.

TL;DR Login for each request is not a required component to implement API security, authentication is.

It is hard to answer your question about login without talking about security in general. With some authentication schemes, there's no traditional login.

REST does not dictate any security rules, but the most common implementation in practice is OAuth with 3-way authentication (as you've mentioned in your question). There is no log-in per se, at least not with each API request. With 3-way auth, you just use tokens.

1. User approves API client and grants permission to make requests in the form of a long-lived token
2. Api client obtains a short-lived token by using the long-lived one.
3. Api client sends the short-lived token with each request.

This scheme gives the user the option to revoke access at any time. Practially all publicly available RESTful APIs I've seen use OAuth to implement this.

I just don't think you should frame your problem (and question) in terms of login, but rather think about securing the API in general.

For further info on authentication of REST APIs in general, you can look at the following resources:

• http://www.infoq.com/news/2010/01/rest-api-authentication-schemes
• REST API Authentication
• RESTful API Authentication

You can use .text-reset class to reset the color from default blue to anything you want. Hopefully this is helpful.

for me the problem was solved by installing another supportive package.

so I installed graphviz package through anaconda then I failed to import it

after that I installed a second package named python-graphviz also through anaconda

then I succeeded in importing graphviz module into my code

I hope this will help someone :)

If you want to treat accented latin characters (eg. à Ñ) as normal letters (ie. avoid matching them too), you'll also need to include the appropriate Unicode range (\u00C0-\u00FF) in your regex, so it would look like this:

/[^a-zA-Z\d\s:\u00C0-\u00FF]/g

• ^ negates what follows
• a-zA-Z matches upper and lower case letters
• \d matches digits
• \s matches white space (if you only want to match spaces, replace this with a space)
• : matches a colon
• \u00C0-\u00FF matches the Unicode range for accented latin characters.

nb. Unicode range matching might not work for all regex engines, but the above certainly works in Javascript (as seen in this pen on Codepen).

nb2. If you're not bothered about matching underscores, you could replace a-zA-Z\d with \w, which matches letters, digits, and underscores.

This works on SQL Server 2005 and if there is maximal number:

SELECT * 
FROM
  (SELECT ROW_NUMBER() OVER(ORDER BY a.id) NUMBER
  FROM syscomments a
  CROSS JOIN syscomments b) c
WHERE c.NUMBER IN (1,4,6,7,9)

You can assign the any type to the object:

let bar: any = {};
bar.foo = "foobar"; 

This is the correct answer to auto hide of zero value and cell shows blank for zero value only follow:

1. Click the office button (top left)
2. Click "Excel Options"
3. Click "Advanced"
4. Scroll down to "Display options for this worksheet"
5. Untick the box "Show a zero in cells that have zero value"
6. Click "okay"

cut -d ' ' -f 2

Where 2 is the field number of the space-delimited field you want.

Here is my working env path variables after much troubleshooting

CLASSPATH

.;C:\Program Files (x86)\Java\jre7\lib\ext\QTJava.zip;C:\Program Files (x86)\Java\jdk1.6.0_27\bin

PATH <---sometimes this PATH fills up with too many paths and you can't add a path(which was my case!)

bunchofpaths;C:\Program Files (x86)\Java\jdk1.6.0_27\bin

Additionally, when you try to use the cmd to execute the file...make sure your in the local directory as the file your trying to execute (which you did.)

Just a little checklist for people that have this problem still.

when I ran (as suggested above):

>>> a = [(1, u'abc'), (2, u'def')]
>>> import operator
>>> b = map(operator.itemgetter(0), a)
>>> b

instead of returning:

[1, 2]

I received this as the return:

<map at 0xb387eb8>

I found I had to use list():

>>> b = list(map(operator.itemgetter(0), a))

to successfully return a list using this suggestion. That said, I'm happy with this solution, thanks. (tested/run using Spyder, iPython console, Python v3.6)

The Singleton Pattern implemented with Python courtesy of ActiveState.

It looks like the trick is to put the class that's supposed to only have one instance inside of another class.

There is actually quite a difference, a solutions architect looks a a requirement holistically, say for example the requirement is to reduce the number of staff in a call center taking Pizza orders, a solutions architect looks at all of the component pieces that will have to come together to satisfy this, things like what voice recognition software to use, what hardware is required, what OS would be best suited to host it, integration of the IVR software with the provisioning system etc.

An application archirect in this scenario on the other hand deals with the specifics of how the software will interact, what language is best suited, how to best use any existing api's, creating an api if none exists etc.

Both have their place, both tasks must be done in order to staisfy the requirement and in large orgs you will have dedicated people doing it, in smaller dev shops often times a developer will have to pick up all of the architectural tasks as part of the overall development, because there is no-one else, imo its overly cynical to say that its just a marketing term, it is a real role (even if it's the dev picking it up ad-hoc) and particulary valuable at project kick-off.

Jenkins lets you set up multiple times, separated by line breaks.

If you need it to build daily at 7 am, along with every Sunday at 4 pm, the below works well.

If you want to remove only one saved password, e.g. for "user1":

• Go to the saved password directory (*c:\Users\USERNAME\AppData\Roaming\Subversion\auth\svn.simple\*)
• You will find several files in this folder (named with hash value)
• Find the file which contains the username "user1", which you want to change (open it with Notepad).
• Remove the file.
• Next time you will connect to your SVN server, Tortoise will prompt you for new username and password.

You may try with below query :

INSERT INTO errortable (dateupdated,table1id)
VALUES (to_date(to_char(sysdate,'dd/mon/yyyy hh24:mi:ss'), 'dd/mm/yyyy hh24:mi:ss' ),1083 );

To view the result of it:

SELECT to_char(hire_dateupdated, 'dd/mm/yyyy hh24:mi:ss') 
FROM errortable 
    WHERE table1id = 1083;

Format like this while selecting:

to_char(systimestamp, 'DD-MON-YYYY')

Eg:

select to_char(systimestamp, 'DD-MON-YYYY') from dual;

Try this:

var keys = [];
for (var key in dictionary) {
  if (dictionary.hasOwnProperty(key)) {
    keys.push(key);
  }
}

hasOwnProperty is needed because it's possible to insert keys into the prototype object of dictionary. But you typically don't want those keys included in your list.

For example, if you do this:

Object.prototype.c = 3;
var dictionary = {a: 1, b: 2};

and then do a for...in loop over dictionary, you'll get a and b, but you'll also get c.

What you are looking to do is get the position using the LocationManager.NETWORK_PROVIDER instead of LocationManager.GPS_PROVIDER. The NETWORK_PROVIDER will resolve on the GSM or wifi, which ever available. Obviously with wifi off, GSM will be used. Keep in mind that using the cell network is accurate to basically 500m.

http://developer.android.com/guide/topics/location/obtaining-user-location.html has some really great information and sample code.

After you get done with most of the code in OnCreate(), add this:

// Acquire a reference to the system Location Manager
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

// Define a listener that responds to location updates
LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
      // Called when a new location is found by the network location provider.
      makeUseOfNewLocation(location);
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {}

    public void onProviderEnabled(String provider) {}

    public void onProviderDisabled(String provider) {}
  };

// Register the listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);

You could also have your activity implement the LocationListener class and thus implement onLocationChanged() in your activity.

well, I know that I'm a bit too late, but I tried all of your solutions and with no success! So here is how I managed to do it. First of all, I'm working on an Asp.Net MVC project. The Only thing I changed was in my c# method getInvitation:

public ActionResult getInvitation (Guid s_ID)
{
    using (var db = new cRM_Verband_BWEntities())
    {
        var listSidsMit = (from data in db.TERMINEINLADUNGEN where data.RECID_KOMMUNIKATIONEN == s_ID select data.RECID_MITARBEITER.ToString()).ToArray();
        return Json(listSidsMit);
    }
}

SuccessFunction in JS :

function successFunction(result) {
    console.log(result);
}

I changed the Method Type from string[] to ActionResult and of course at the end I wrapped my array listSidsMit with the Json method.

The INotifyPropertyChanged interface is implemented with events. The interface has just one member, PropertyChanged, which is an event that consumers can subscribe to.

The version that Richard posted is not safe. Here is how to safely implement this interface:

public class MyClass : INotifyPropertyChanged
{
    private string imageFullPath;

    protected void OnPropertyChanged(PropertyChangedEventArgs e)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
            handler(this, e);
    }

    protected void OnPropertyChanged(string propertyName)
    {
        OnPropertyChanged(new PropertyChangedEventArgs(propertyName));
    }

    public string ImageFullPath
    {
        get { return imageFullPath; }
        set
        {
            if (value != imageFullPath)
            {
                imageFullPath = value;
                OnPropertyChanged("ImageFullPath");
            }
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
}

Note that this does the following things:

• Abstracts the property-change notification methods so you can easily apply this to other properties;

• Makes a copy of the PropertyChanged delegate before attempting to invoke it (failing to do this will create a race condition).

• Correctly implements the INotifyPropertyChanged interface.

If you want to additionally create a notification for a specific property being changed, you can add the following code:

protected void OnImageFullPathChanged(EventArgs e)
{
    EventHandler handler = ImageFullPathChanged;
    if (handler != null)
        handler(this, e);
}

public event EventHandler ImageFullPathChanged;

Then add the line OnImageFullPathChanged(EventArgs.Empty) after the line OnPropertyChanged("ImageFullPath").

Since we have .Net 4.5 there exists the CallerMemberAttribute, which allows to get rid of the hard-coded string for the property name in the source code:

    protected void OnPropertyChanged(
        [System.Runtime.CompilerServices.CallerMemberName] string propertyName = "")
    {
        OnPropertyChanged(new PropertyChangedEventArgs(propertyName));
    }

    public string ImageFullPath
    {
        get { return imageFullPath; }
        set
        {
            if (value != imageFullPath)
            {
                imageFullPath = value;
                OnPropertyChanged();
            }
        }
    }

Use immediate children selector >:

$('#tblOne > tbody  > tr')

Description: Selects all direct child elements specified by "child" of elements specified by "parent".

In addition to the above answers, I would say for columns having no single word name, you may use:-

df[df['Product ID'].str.contains("foo") == True]

Hope this helps.

Can I see your User class? This is just using restrictions below. I don't see why Restrictions would be really any different than Examples (I think null fields get ignored by default in examples though).

getCurrentSession().createCriteria(User.class)
.setProjection( Projections.distinct( Projections.projectionList()
.add( Projections.property("name"), "name")
.add( Projections.property("city"), "city")))
.add( Restrictions.eq("city", "TEST")))
.setResultTransformer(Transformers.aliasToBean(User.class))
.list();

I've never used the alaistToBean, but I just read about it. You could also just loop over the results..

List<Object> rows = criteria.list();
for(Object r: rows){
  Object[] row = (Object[]) r;
  Type t = ((<Type>) row[0]);
}

If you have to you can manually populate User yourself that way.

Its sort of hard to look into the issue without some more information to diagnose the issue.

It's related absolutely to your terminal. VTE doesn't support blink, If you use gnome-terminal, tilda, guake, terminator, xfce4-terminal and so on according to VTE, you won't have blink.
If you use or want to use blink on VTE, you have to use xterm.
You can use infocmp command with terminal name:

#infocmp vt100
#infocmp xterm
#infocmp vte

For example :

# infocmp vte

The problem has to do with the async attribute in the script tag. The Callback Function is trying to call "initMap()" when it doesn't really exists by the time the request finished.

To solve this I placed the Goole Maps Api Script bellow the script where my initMap function was declared.

Hope this helps

sys.columns.is_identity = 1

e.g.,

select o.name, c.name
from sys.objects o inner join sys.columns c on o.object_id = c.object_id
where c.is_identity = 1

As others have mentioned, you could use a comparison function, but you can also overload the < operator and the default less<T> functor will work as well:

struct data {
    string word;
    int number;
    bool operator < (const data& rhs) const {
        return word.size() < rhs.word.size();
    }
};

Then it's just:

std::sort(info.begin(), info.end());

Edit

As James McNellis pointed out, sort does not actually use the less<T> functor by default. However, the rest of the statement that the less<T> functor will work as well is still correct, which means that if you wanted to put struct datas into a std::map or std::set this would still work, but the other answers which provide a comparison function would need additional code to work with either.

I've tried some of those solution but nothing was working for me. I try this simple thing :

$isJson = json_decode($myJSON);

if ($isJson instanceof \stdClass || is_array($isJson)) {
   echo("it's JSON confirmed");
} else {
   echo("nope");
}

I think it's a fine solutiuon since JSON decode without the second parameter give an object.

EDIT : If you know what will be the input, you can adapt this code to your needs. In my case I know I have a Json wich begin by "{", so i don't need to check if it's an array.

Something like this? Takes advantage of short-circuit evaluation. If the file does not exist, the whole conditional cannot be true, so python will not bother evaluation the second part.

os.path.exists("gogogo.php") and os.remove("gogogo.php")

Could you not cast your result as numeric(x,2)? Where x <= 38

select 
    round(630/60.0,2), 
    cast(round(630/60.0,2) as numeric(36,2))

Returns

10.500000   10.50

int screenResolution = Toolkit.getDefaultToolkit().getScreenResolution();
System.out.println(""+screenResolution);

The "reference" Java implementation by Sean Leary is here on github. Make sure to have the latest version - different libraries pull in versions buggy old versions from 2009.

Java EE 7 has a JSON API in javax.json, see the Javadoc. From what I can tell, it doesn't have a simple method to marshall any object to JSON, you need to construct a JsonObject or a JsonArray.

import javax.json.*;

JsonObject value = Json.createObjectBuilder()
 .add("firstName", "John")
 .add("lastName", "Smith")
 .add("age", 25)
 .add("address", Json.createObjectBuilder()
     .add("streetAddress", "21 2nd Street")
     .add("city", "New York")
     .add("state", "NY")
     .add("postalCode", "10021"))
 .add("phoneNumber", Json.createArrayBuilder()
     .add(Json.createObjectBuilder()
         .add("type", "home")
         .add("number", "212 555-1234"))
     .add(Json.createObjectBuilder()
         .add("type", "fax")
         .add("number", "646 555-4567")))
 .build();

JsonWriter jsonWriter = Json.createWriter(...);
jsonWriter.writeObject(value);
jsonWriter.close();

But I assume the other libraries like GSON will have adapters to create objects implementing those interfaces.

For this (and most plotting) I would not rely on the Pandas wrappers to matplotlib. Instead, just use matplotlib directly:

import matplotlib.pyplot as plt
plt.scatter(df['col_name_1'], df['col_name_2'])
plt.show() # Depending on whether you use IPython or interactive mode, etc.

and remember that you can access a NumPy array of the column's values with df.col_name_1.values for example.

I ran into trouble using this with Pandas default plotting in the case of a column of Timestamp values with millisecond precision. In trying to convert the objects to datetime64 type, I also discovered a nasty issue: < Pandas gives incorrect result when asking if Timestamp column values have attr astype >.

The encodings are spelled out in the buffer documentation.

Buffers and character encodings:

Character Encodings

• utf8: Multi-byte encoded Unicode characters. Many web pages and other document formats use UTF-8. This is the default character encoding.
• utf16le: Multi-byte encoded Unicode characters. Unlike utf8, each character in the string will be encoded using either 2 or 4 bytes.
• latin1: Latin-1 stands for ISO-8859-1. This character encoding only supports the Unicode characters from U+0000 to U+00FF.

Binary-to-Text Encodings

• base64: Base64 encoding. When creating a Buffer from a string, this encoding will also correctly accept "URL and Filename Safe Alphabet" as specified in RFC 4648, Section 5.
• hex: Encode each byte as two hexadecimal characters.

Legacy Character Encodings

• ascii: For 7-bit ASCII data only. Generally, there should be no reason to use this encoding, as 'utf8' (or, if the data is known to always be ASCII-only, 'latin1') will be a better choice when encoding or decoding ASCII-only text.
• binary: Alias for 'latin1'.
• ucs2: Alias of 'utf16le'.

You want getActivity() inside your class. It's better to use

yourclassname.this.getActivity()

Try this. It's helpful for you.

If you're using 1.9.2 or above, you can convert hashes and arrays to nested JSON objects just using to_json.

{a: [1,2,3], b: 4}.to_json

In Rails, you can call to_json on Active Record objects. You can pass :include and :only parameters to control the output:

@user.to_json only: [:name, :email]

You can also call to_json on AR relations, like so:

User.order("id DESC").limit(10).to_json

You don't need to import anything and it all works exactly as you'd hope.

Try this code:

var id;
var vname;
function ajaxCall(){
for(var q = 1; q<=10; q++){
 $.ajax({                                            
     url: 'api.php',                        
     data: 'id1='+q+'',                                                         
     dataType: 'json',
     async:false,                    
     success: function(data)          
     {   
        id = data[0];              
        vname = data[1];
     },
    complete: function (data) {
      printWithAjax(); 
     }
    });

  }//end of the for statement
  }//end of ajax call function

The "complete" function executes only after the "success" of ajax. So try to call the printWithAjax() on "complete". This should work for you.

Here is my solution. I first create random numbers with random.uniform, format them in to string with double precision and then convert them back to float. You can adjust the precision by changing '.2f' to '.3f' etc..

import random
from decimal import Decimal

GndSpeedHigh = float(format(Decimal(random.uniform(5, 25)), '.2f'))
GndSpeedLow = float(format(Decimal(random.uniform(2, GndSpeedHigh)), '.2f'))
GndSpeedMean = float(Decimal(format(GndSpeedHigh + GndSpeedLow) / 2, '.2f')))
print(GndSpeedMean)

I make a (sub)folder named "hide", move the file I don't want committed to there. Then do my commit, ignoring complaint about the missing file. Then move the hidden file from hide back to ./

I know of no downside to this tactic.

This does not work in Python 3.

You can use functools cmp_to_key to have old-style comparison functions work though.

from functools import cmp_to_key

def cmp_items(a, b):
    if a.foo > b.foo:
        return 1
    elif a.foo == b.foo:
        return 0
    else:
        return -1

cmp_items_py3 = cmp_to_key(cmp_items)

alist.sort(cmp_items_py3)

The reason #2 fails is because sys.modules['module'] does not exist (the import routine has its own scope, and cannot see the module local name), and there's no module module or package on-disk. Note that you can separate multiple imported names by commas.

from package.subpackage.module import attribute1, attribute2, attribute3

Also:

from package.subpackage import module
print module.attribute1

Only a manual deletion of the specific dependency in the cache folder works... an artifactory built by a colleague in enterprise repo.

When debugging lines of code, here are the usual scenarios:

• (Step Into) A method is about to be invoked, and you want to debug into the code of that method, so the next step is to go into that method and continue debugging step-by-step.
• (Step Over) A method is about to be invoked, but you're not interested in debugging this particular invocation, so you want the debugger to execute that method completely as one entire step.
• (Step Return) You're done debugging this method step-by-step, and you just want the debugger to run the entire method until it returns as one entire step.
• (Resume) You want the debugger to resume "normal" execution instead of step-by-step
• (Line Breakpoint) You don't care how it got there, but if execution reaches a particular line of code, you want the debugger to temporarily pause execution there so you can decide what to do.

Eclipse has other advanced debugging features, but these are the basic fundamentals.

Just to complement the answer that I thought best, I also use less -SFX but in a different way: I like to ad it to my .my.cnf file in my home folder, an example cnf file looks like this:

[client]
user=root
password=MyPwD
[mysql]
pager='less -SFX'

The good thing about having it this way, is that less is only used when the output of a query is actually more than one page long, here is the explanation of all the flags:

• -S: Single line, don't skip line when line is wider than screen, instead allow to scroll to the right.
• -F: Quit if one screen, if content doesn't need scrolling then just send to stdout.
• -X: No init, disables any output "less" might have configured to output every time it loads.

Note: in the .my.cnf file don't put the pager command below the [client] keyword; although it might work with mysql well, mysqldump will complain about not recognizing it.

I know this question is old but it can be done in one line of code

String deviceID = Build.SERIAL;

KeyStore Explorer open source visual tool to manage keystores.

Check the GridView1.SelectedRow is not null:

if (GridView1.SelectedRow == null) return;
string DeleteThis = GridView1.SelectedRow.Cells[0].Text;

A key point that I find missing in the above answers is that urllib returns an object of type <class http.client.HTTPResponse> whereas requests returns <class 'requests.models.Response'>.

Due to this, read() method can be used with urllib but not with requests.

P.S. : requests is already rich with so many methods that it hardly needs one more as read() ;>

Try this:

 $(document).mouseup(function (e) {
    var div = $("#yourdivid");
    if (!div.is(e.target) && div.has(e.target).length === 0) 
    {
       div.hide();
     }
    });

Time and Space complexity are different aspects of calculating the efficiency of an algorithm.

Time complexity deals with finding out how the computational time of an algorithm changes with the change in size of the input.

On the other hand, space complexity deals with finding out how much (extra)space would be required by the algorithm with change in the input size.

To calculate time complexity of the algorithm the best way is to check if we increase in the size of the input, will the number of comparison(or computational steps) also increase and to calculate space complexity the best bet is to see additional memory requirement of the algorithm also changes with the change in the size of the input.

A good example could be of Bubble sort.

Lets say you tried to sort an array of 5 elements. In the first pass you will compare 1st element with next 4 elements. In second pass you will compare 2nd element with next 3 elements and you will continue this procedure till you fully exhaust the list.

Now what will happen if you try to sort 10 elements. In this case you will start with comparing comparing 1st element with next 9 elements, then 2nd with next 8 elements and so on. In other words if you have N element array you will start of by comparing 1st element with N-1 elements, then 2nd element with N-2 elements and so on. This results in O(N^2) time complexity.

But what about size. When you sorted 5 element or 10 element array did you use any additional buffer or memory space. You might say Yes, I did use a temporary variable to make the swap. But did the number of variables changed when you increased the size of array from 5 to 10. No, Irrespective of what is the size of the input you will always use a single variable to do the swap. Well, this means that the size of the input has nothing to do with the additional space you will require resulting in O(1) or constant space complexity.

Now as an exercise for you, research about the time and space complexity of merge sort

Tims answer seems to me as misleading. Especially when urllib2 does not return expected code. For example this Error will be fatal (believe or not - it is not uncommon one when downloading urls):

AttributeError: 'URLError' object has no attribute 'code'

Fast, but maybe not the best solution would be code using nested try/except block:

import urllib2
try:
    urllib2.urlopen("some url")
except urllib2.HTTPError, err:
    try:
        if err.code == 404:
            # Handle the error
        else:
            raise
    except:
        ...

More information to the topic of nested try/except blocks Are nested try/except blocks in python a good programming practice?

It's not built in, but I've seen / used this code. This allows you to use this:

[mapView setCenterCoordinate:myCoord zoomLevel:13 animated:YES];

Note: This is not my code, I did not write it, so therefore can't take credit for it

In one line of code as below :

<p> cursor on text field shows text .if not password will be shown</p>_x000D_
<input type="password" name="txt_password" onmouseover="this.type='text'"_x000D_
       onmouseout="this.type='password'" placeholder="password" />

Take a look in .git/config and make the changes you need.

Alternatively you could use

git remote rm [name of the url you sets on adding]

and

git remote add [name] [URL]

Or just

git remote set-url [URL]

Before you do anything wrong, double check with

git help remote

Did you write the SyndFeed?

Does sf.getEntries return List or List<SyndEntry>? My guess is it returns List and changing it to return List<SyndEntry> will fix the problem.

If SyndFeed is part of a library, I don't think you can remove the warning without adding the @SuppressWarning("unchecked") annotation to your method.

I was also struggling with same issue. The bootstrap classes I use are not working for me. I came up with an workaround, as below:

<form action='...' method='POST' class='form-group'>
  <div class="form-horizontal">
    <input type="text" name="..." 
        class="form-control" 
        placeholder="Search People..."
        style="width:280px;max-width:280px;display:inline-block"/>

    <button type="submit" 
        class="btn btn-primary" 
        style="margin-left:-8px;margin-top:-2px;min-height:36px;">
      <i class="glyphicon glyphicon-search"></i>
     </button>
  </div>
</form>

Basically, I overrode the display property of class "form-control", and used other style properties for correcting the size and position.

Following is the result:

from within the git bash shell type:

>cd /bin
>ls -l

You will then see a long listing of all the unix-like commands available. There are lots of goodies in there.

Pickling will serialize your list (convert it, and it's entries to a unique byte string), so you can save it to disk. You can also use pickle to retrieve your original list, loading from the saved file.

So, first build a list, then use pickle.dump to send it to a file...

In my case, I already had a period(.) and also a comma(,), so what worked for me was to replace the comma(,) with an empty string like below:

parseFloat('3,000.78'.replace(',', '')) 

This is assuming that the amount from the existing database is 3,000.78. The results are: 3000.78 without the initial comma(,).

When you use scanner, as mentioned by Alnitak, you only get 'false' for hasNext() when you have a EOF character, basically... You cannot easily send and EOF character using the keyboard, therefore in situations like this, it's common to have a special character or word which you can send to stop execution, for example:

String s1 = sc.next();
if (s1.equals("exit")) {
    break;
}

Break will get you out of the loop.

PURE CSS AND HTML (as asked) with ANIMATIONS!

Example Image (you can run the code below):

After looking for something really clean and straight forward, I ended up building this with ONE simple change from another code that was built only thinking on checkboxes, so I tryed the funcionality for RADIOS and it worked too(!).

The CSS (SCSS) is fully from @mallendeo (as established on the JS credits), what I did was simply change the type of the input to RADIO, and gave the same name to all the radio switches.... and VOILA!! They deactivate automatically one to the other!!

Very clean, and as you asked it's only CSS and HTML!!

It is exactly what I was looking for since 3 days after trying and editing more than a dozen of options (which mostly requiered jQuery, or didn't allow labels, or even wheren't really compatible with current browsers). This one's got it all!

If you run the snippet, you'll see I leave the iOS radio checked and disabled, so you can watch how it is also affected when activating another one. I also included 2 labels for each radio, one before and one after. The copy of the original code to show the working checkboxes in the same window is also included.

There is text-decoration-thickness, currently part of CSS Text Decoration Module Level 4. It's at "Editor's Draft" stage - so it's a work in progress and subject to change. As of January 2020, it is only supported in Firefox and Safari.

The text-decoration-thickness CSS property sets the thickness, or width, of the decoration line that is used on text in an element, such as a line-through, underline, or overline.

a {
  text-decoration-thickness: 2px;
}

Codepen: https://codepen.io/mrotaru/pen/yLyLOgr (Firefox only)

There's also text-decoration-color, which is part of CSS Text Decoration Module Level 3. This is more mature (Candidate Recommendation) and is supported in most major browsers (exceptions are Edge and IE). Of course it can't be used to alter the thickness of the line, but can be used to achieve a more "muted" underline (also shown in the codepen).

You can do this with a pivot table and add a line with the pourcentage for each category like brettdj showed in his answer. But if you want to keep your data as it is, there is a solution by using some javascript.

Javascript is a powerful language offering a lot of useful data visualization libraries like plotly.js.

Here is a working code I have written for you:

https://www.funfun.io/1/#/edit/5a58c6368dfd67466879ed27

In this example, I use a Json file to get the data from the embedded spreadsheet, so I can use it in my javascript code and create a bar chart.

I calculate the percentage by adding the values of all the category present in the table and using this formula (you can see it in the script.js file): Percentage (%) = 100 x partial value / total value

It automatically calculates the total and pourcentage even if you add more categories.

I used plotly.js to create my chart, it has a good documentation and lots of examples for beginners, this code gets all the option you want to use:

var trace1 = {
    x: xValue, 
    y: data,
    type: 'bar',
    text: yValue,
    textposition: 'auto',
    hoverinfo: 'none',
    marker: {
    color: 'yellow',
    opacity: 0.6,
    line: {
      color: 'yellow',
      width: 1.5
    }
  }
};

It is rather self explanatory, the text is where you put the percentage.

Once you've made your chart you can load it in excel by passing the URL in the Funfun add-in. Here is how it looks like with my example:

I know it is an old post but I hope it helps people with the same problem !

Disclosure : I’m a developer of funfun

The simplest way would be QString::toStdString().

Try this

select count(*) from table where cast(col as double) is null;

1. You should add L: long i = 12345678910L;.
2. Yes.

BTW: it doesn't have to be an upper case L, but lower case is confused with 1 many times :).

If you are using Databricks and can fit all the data into RAM on one worker (and thus can use .coalesce(1)), you can use dbfs to find and move the resulting CSV file:

val fileprefix= "/mnt/aws/path/file-prefix"

dataset
  .coalesce(1)       
  .write             
//.mode("overwrite") // I usually don't use this, but you may want to.
  .option("header", "true")
  .option("delimiter","\t")
  .csv(fileprefix+".tmp")

val partition_path = dbutils.fs.ls(fileprefix+".tmp/")
     .filter(file=>file.name.endsWith(".csv"))(0).path

dbutils.fs.cp(partition_path,fileprefix+".tab")

dbutils.fs.rm(fileprefix+".tmp",recurse=true)

If your file does not fit into RAM on the worker, you may want to consider chaotic3quilibrium's suggestion to use FileUtils.copyMerge(). I have not done this, and don't yet know if is possible or not, e.g., on S3.

This answer is built on previous answers to this question as well as my own tests of the provided code snippet. I originally posted it to Databricks and am republishing it here.

The best documentation for dbfs's rm's recursive option I have found is on a Databricks forum.

The route engine uses the same sequence as you add rules into it. Once it gets the first matched rule, it will stop checking other rules and take this to search for controller and action.

So, you should:

1. Put your specific rules ahead of your general rules(like default), which means use RouteTable.Routes.MapHttpRoute to map "WithActionApi" first, then "DefaultApi".

2. Remove the defaults: new { id = System.Web.Http.RouteParameter.Optional } parameter of your "WithActionApi" rule because once id is optional, url like "/api/{part1}/{part2}" will never goes into "DefaultApi".

3. Add an named action to your "DefaultApi" to tell the route engine which action to enter. Otherwise once you have more than one actions in your controller, the engine won't know which one to use and throws "Multiple actions were found that match the request: ...". Then to make it matches your Get method, use an ActionNameAttribute.

So your route should like this:

// Map this rule first
RouteTable.Routes.MapRoute(
     "WithActionApi",
     "api/{controller}/{action}/{id}"
 );

RouteTable.Routes.MapRoute(
    "DefaultApi",
    "api/{controller}/{id}",
    new { action="DefaultAction", id = System.Web.Http.RouteParameter.Optional }
);

And your controller:

[ActionName("DefaultAction")] //Map Action and you can name your method with any text
public string Get(int id)
{
    return "object of id id";
}        

[HttpGet]
public IEnumerable<string> ByCategoryId(int id)
{
    return new string[] { "byCategory1", "byCategory2" };
}

I personally prefer the simpler syntax of the ~ operator.

SELECT id FROM TAG_TABLE WHERE 'aaaaaaaa' ~ tag_name;

Worth reading through Difference between LIKE and ~ in Postgres to understand the difference. `

This file works properly as it is: just copy and paste in your computer. Surfing on the web I have found this easy implementation on wikipedia page here. The page is in italian, so I re-wrote the code with some translations. Here there are almost the same informations but in english. ENJOY!

"an object" of what type?

You can certainly assign NULL (and nullptr) to objects of pointer types, and it is implementation defined if you can assign NULL to objects of arithmetic types.

If you mean objects of some class type, the answer is NO (excepting classes that have operator= accepting pointer or arithmetic types)

"empty" is more plausible, as many types have both copy assignment and default construction (often implicitly). To see if an existing object is like a default constructed one, you will also need an appropriate bool operator==

Like Robert K said, don't use jQuery.html().text() to decode html entities as it's unsafe because user input should never have access to the DOM. Read about XSS for why this is unsafe.

Instead try the Underscore.js utility-belt library which comes with escape and unescape methods:

_.escape(string)

Escapes a string for insertion into HTML, replacing &, <, >, ", `, and ' characters.

_.escape('Curly, Larry & Moe');
=> "Curly, Larry & Moe"

_.unescape(string)

The opposite of escape, replaces &, <, >, ", ` and ' with their unescaped counterparts.

_.unescape('Curly, Larry & Moe');
=> "Curly, Larry & Moe"

To support decoding more characters, just copy the Underscore unescape method and add more characters to the map.

Another option is:

for i in *001.jpg
do
  echo "mv $i yourstring${i#*001.jpg}"
done

remove echo after you have it right.

Parameter substitution with # will keep only the last part, so you can change its name.

Yet another way to plot the sine wave.

import numpy as np
import matplotlib
matplotlib.use('TKAgg') #use matplotlib backend TKAgg (optional)
import matplotlib.pyplot as plt

t = np.linspace(0.0, 5.0, 50000)       # time axis
sig = np.sin(t)
plt.plot(t,sig)

It's depends on if your computer support WMI. My computer can't run this WMI demo too.

But I successfully get the CPU temperature via Open Hardware Monitor. Add the Openhardwaremonitor reference in Visual Studio. It's easier. Try this

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using OpenHardwareMonitor.Hardware;
namespace Get_CPU_Temp5
{
   class Program
   {
       public class UpdateVisitor : IVisitor
       {
           public void VisitComputer(IComputer computer)
           {
               computer.Traverse(this);
           }
           public void VisitHardware(IHardware hardware)
           {
               hardware.Update();
               foreach (IHardware subHardware in hardware.SubHardware) subHardware.Accept(this);
           }
           public void VisitSensor(ISensor sensor) { }
           public void VisitParameter(IParameter parameter) { }
       }
       static void GetSystemInfo()
       {
           UpdateVisitor updateVisitor = new UpdateVisitor();
           Computer computer = new Computer();
           computer.Open();
           computer.CPUEnabled = true;
           computer.Accept(updateVisitor);
           for (int i = 0; i < computer.Hardware.Length; i++)
           {
               if (computer.Hardware[i].HardwareType == HardwareType.CPU)
               {
                   for (int j = 0; j < computer.Hardware[i].Sensors.Length; j++)
                   {
                       if (computer.Hardware[i].Sensors[j].SensorType == SensorType.Temperature)
                               Console.WriteLine(computer.Hardware[i].Sensors[j].Name + ":" + computer.Hardware[i].Sensors[j].Value.ToString() + "\r");
                   }
               }
           }
           computer.Close();
       }
       static void Main(string[] args)
       {
           while (true)
           {
               GetSystemInfo();
           }
       }
   }
}

Real, User and Sys process time statistics

One of these things is not like the other. Real refers to actual elapsed time; User and Sys refer to CPU time used only by the process.

• Real is wall clock time - time from start to finish of the call. This is all elapsed time including time slices used by other processes and time the process spends blocked (for example if it is waiting for I/O to complete).

• User is the amount of CPU time spent in user-mode code (outside the kernel) within the process. This is only actual CPU time used in executing the process. Other processes and time the process spends blocked do not count towards this figure.

• Sys is the amount of CPU time spent in the kernel within the process. This means executing CPU time spent in system calls within the kernel, as opposed to library code, which is still running in user-space. Like 'user', this is only CPU time used by the process. See below for a brief description of kernel mode (also known as 'supervisor' mode) and the system call mechanism.

User+Sys will tell you how much actual CPU time your process used. Note that this is across all CPUs, so if the process has multiple threads (and this process is running on a computer with more than one processor) it could potentially exceed the wall clock time reported by Real (which usually occurs). Note that in the output these figures include the User and Sys time of all child processes (and their descendants) as well when they could have been collected, e.g. by wait(2) or waitpid(2), although the underlying system calls return the statistics for the process and its children separately.

Origins of the statistics reported by time (1)

The statistics reported by time are gathered from various system calls. 'User' and 'Sys' come from wait (2) (POSIX) or times (2) (POSIX), depending on the particular system. 'Real' is calculated from a start and end time gathered from the gettimeofday (2) call. Depending on the version of the system, various other statistics such as the number of context switches may also be gathered by time.

On a multi-processor machine, a multi-threaded process or a process forking children could have an elapsed time smaller than the total CPU time - as different threads or processes may run in parallel. Also, the time statistics reported come from different origins, so times recorded for very short running tasks may be subject to rounding errors, as the example given by the original poster shows.

A brief primer on Kernel vs. User mode

On Unix, or any protected-memory operating system, 'Kernel' or 'Supervisor' mode refers to a privileged mode that the CPU can operate in. Certain privileged actions that could affect security or stability can only be done when the CPU is operating in this mode; these actions are not available to application code. An example of such an action might be manipulation of the MMU to gain access to the address space of another process. Normally, user-mode code cannot do this (with good reason), although it can request shared memory from the kernel, which could be read or written by more than one process. In this case, the shared memory is explicitly requested from the kernel through a secure mechanism and both processes have to explicitly attach to it in order to use it.

The privileged mode is usually referred to as 'kernel' mode because the kernel is executed by the CPU running in this mode. In order to switch to kernel mode you have to issue a specific instruction (often called a trap) that switches the CPU to running in kernel mode and runs code from a specific location held in a jump table. For security reasons, you cannot switch to kernel mode and execute arbitrary code - the traps are managed through a table of addresses that cannot be written to unless the CPU is running in supervisor mode. You trap with an explicit trap number and the address is looked up in the jump table; the kernel has a finite number of controlled entry points.

The 'system' calls in the C library (particularly those described in Section 2 of the man pages) have a user-mode component, which is what you actually call from your C program. Behind the scenes, they may issue one or more system calls to the kernel to do specific services such as I/O, but they still also have code running in user-mode. It is also quite possible to directly issue a trap to kernel mode from any user space code if desired, although you may need to write a snippet of assembly language to set up the registers correctly for the call.

More about 'sys'

There are things that your code cannot do from user mode - things like allocating memory or accessing hardware (HDD, network, etc.). These are under the supervision of the kernel, and it alone can do them. Some operations like malloc orfread/fwrite will invoke these kernel functions and that then will count as 'sys' time. Unfortunately it's not as simple as "every call to malloc will be counted in 'sys' time". The call to malloc will do some processing of its own (still counted in 'user' time) and then somewhere along the way it may call the function in kernel (counted in 'sys' time). After returning from the kernel call, there will be some more time in 'user' and then malloc will return to your code. As for when the switch happens, and how much of it is spent in kernel mode... you cannot say. It depends on the implementation of the library. Also, other seemingly innocent functions might also use malloc and the like in the background, which will again have some time in 'sys' then.

This is exactly what you want:

Create a function that takes as input two strings (the source string to be split and the splitlist string of delimiters) and outputs a list of split words:

def split_string(source, splitlist):
    output = []  # output list of cleaned words
    atsplit = True
    for char in source:
        if char in splitlist:
            atsplit = True
        else:

        numero = numero.substring(0,dec+3);

Just look up the files you deleted, inside Recycle Bin. Right click on it and do restore as you do normally with other deleted files. It is similar as you do normally because VS code also uses normal trash of your system.

If this is coming from SQL Server Import Wizard, try editing the definition of the column on the Data Source, it is 50 characters by default, but it can be longer.

Data Soruce -> Advanced -> Look at the column that goes in error -> change OutputColumnWidth to 200 and try again.

Had this issue on my Nexus 7,Nexus 10 & Pixel as well that means in all the emulators.

After days of struggling with this issue, I figured it out finally. Well, there are a lot of answers above which may work or may not for you because their configuration may vary slightly than yours.

I'll tell you my solution:

When creating those emulators, I checked Hardware - GLES 2.0 in Graphics for better performance. And for me it was the issue.

If you've done the same then,

Go to AVD Manager -> Select your emulator -> Click on Edit configuration (in Actions column marked as pencil) -> in Emulated performance - Graphics -> Select Software - GLES 2.0.

Then click on Show Advanced Settings -> Set none for both Front and Back camera and hit Finish.

Now select your emulator in AVD Manager and click on Dropdown arrow in Actions column -> select Cold Boot Now.

And yay you're ready to go

This occurs when there is not a UNIQUE MS-ACCESS key for the table(s) being updated. (Regardless of the SQL schema).

When creating MS-Access Links to SQL tables, you are asked to specify the index (key) at link time. If this is done incorrectly, or not at all, the query against the linked table is not updatable

When linking SQL tables into Access MAKE SURE that when Access prompts you for the index (key) you use exactly what SQL uses to avoid problem(s), although specifying any unique key is all Access needs to update the table.

If you were not the person who originally linked the table, delete the linked table from MS-ACCESS (the link only gets deleted) and re-link it specifying the key properly and all will work correctly.

I needed to export our security log and wanted the date and time in Coordinated Universal Time. This proved to be a challenge to figure out, but so simple to execute:

wevtutil export-log security c:\users\%username%\SECURITYEVENTLOG-%computername%-$(((get-date).ToUniversalTime()).ToString("yyyyMMddTHHmmssZ")).evtx

The magic code is just this part:

$(((get-date).ToUniversalTime()).ToString("yyyyMMddTHHmmssZ"))

Once you clear the interval using clearInterval you could setInterval once again. And to avoid repeating the callback externalize it as a separate function:

var ticker = function() {
    console.log('idle');
};

then:

var myTimer = window.setInterval(ticker, 4000);

then when you decide to restart:

window.clearInterval(myTimer);
myTimer = window.setInterval(ticker, 4000);

I had the same problem. I managed to solve it by simply updating my version of jquery. I was using 1.6.1 and updated to 1.7.1 - no more crashes.

The connection URL should look like this for SQL Server:

jdbc:sqlserver://serverName[\instanceName][:port][;databaseName=your_db_name]

Examples:

jdbc:sqlserver://localhost
jdbc:sqlserver://127.0.0.1\INGESQL:1433;databaseName=datatest
...

echo 'junk "Foo Bar" not empty one "" this "but this" and this neither' | sed 's/[^\"]*\"\([^\"]*\)\"[^\"]*/>\1</g'

This will result in: >Foo Bar<><>but this<

Here I showed the result string between ><'s for clarity, also using the non-greedy version with this sed command we first throw out the junk before and after that ""'s and then replace this with the part between the ""'s and surround this by ><'s.

Form controls are notoriously difficult to style cross-platform/browser. Some browsers will honor a CSS height rule, some won't.

You can try line-height (may need display:block; or display:inline-block;) or top and bottom padding also. If none of those work, that's pretty much it - use a graphic, position the input in the center and set border:none; so it looks like the form control is big but it actually isn't...

You can simply prevent the default behavior of the click event directly in your template.

<a href="#" ng-click="$event.preventDefault();logout()" />

Per the angular documentation,

Directives like ngClick and ngFocus expose a $event object within the scope of that expression.

For one random letter, you can use:

select substring('ABCDEFGHIJKLMNOPQRSTUVWXYZ',
                 (abs(checksum(newid())) % 26)+1, 1)

An important difference between using newid() versus rand() is that if you return multiple rows, newid() is calculated separately for each row, while rand() is calculated once for the whole query.

As many answers in this thread already suggest it is not possible to send a mail from a static HTML page without using PHP or JS. I just wanted to add that there a some great solutions which will take your HTTP Post request generated by your form and create a mail from it. Those solutions are especially useful in case you do not want to add JS or PHP to your website.

Those servers basically can be configured with a mail-server which is responsible for then sending the email. The receiver, subject, body etc. is received by the server from your HTTP(S) post and then stuffed into the mail you want to send. So technically speaking it is still not possible to send mails from your HTML form but the outcome is the same.

Some of these solutions can be bought as SaaS solution or you can host them by yourself. I'll just name a few but I'm sure there are plenty in case anyone is interested in the technology or the service itself.

Nowadays (2016) Apple recommends more and more to use the URL related API of NSURL, NSFileManager etc.

To get the documents directory in iOS and Swift 2 use

let documentDirectoryURL = try! NSFileManager.defaultManager().URLForDirectory(.DocumentDirectory, 
                                 inDomain: .UserDomainMask, 
                        appropriateForURL: nil, 
                                   create: true)

The try! is safe in this case because this standard directory is guaranteed to exist.

Then append the appropriate path component for example an sqlite file

let databaseURL = documentDirectoryURL.URLByAppendingPathComponent("MyDataBase.sqlite")

Now check if the file exists with checkResourceIsReachableAndReturnError of NSURL.

let fileExists = databaseURL.checkResourceIsReachableAndReturnError(nil)

If you need the error pass the NSError pointer to the parameter.

var error : NSError?
let fileExists = databaseURL.checkResourceIsReachableAndReturnError(&error)
if !fileExists { print(error) }

Swift 3+:

let documentDirectoryURL = try! FileManager.default.url(for: .documentDirectory, 
                                in: .userDomainMask, 
                    appropriateFor: nil, 
                            create: true)

let databaseURL = documentDirectoryURL.appendingPathComponent("MyDataBase.sqlite")

checkResourceIsReachable is marked as can throw

do {
    let fileExists = try databaseURL.checkResourceIsReachable()
    // handle the boolean result
} catch let error as NSError {
    print(error)
}

To consider only the boolean return value and ignore the error use the nil-coalescing operator

let fileExists = (try? databaseURL.checkResourceIsReachable()) ?? false

<TextBlock Text="{Binding Date, StringFormat='{}{0:MM/dd/yyyy a\\t h:mm tt}'}" />

will return you

I just love getting information like BalusC gives here - and he is kind enough to help SO many people with such GOOD information that I regard his words as gospel, but I was not able to use that order of events to solve this same kind of timing issue in my project. Since BalusC put a great general reference here that I even bookmarked, I thought I would donate my solution for some advanced timing issues in the same place since it does solve the original poster's timing issues as well. I hope this code helps someone:

        <p:pickList id="formPickList" 
                    value="#{mediaDetail.availableMedia}" 
                    converter="MediaPicklistConverter" 
                    widgetVar="formsPicklistWidget" 
                    var="mediaFiles" 
                    itemLabel="#{mediaFiles.mediaTitle}" 
                    itemValue="#{mediaFiles}" >
            <f:facet name="sourceCaption">Available Media</f:facet>
            <f:facet name="targetCaption">Chosen Media</f:facet>
        </p:pickList>

        <p:commandButton id="viewStream_btn" 
                         value="Stream chosen media" 
                         icon="fa fa-download"
                         ajax="true"
                         action="#{mediaDetail.prepareStreams}"                                              
                         update=":streamDialogPanel"
                         oncomplete="PF('streamingDialog').show()"
                         styleClass="ui-priority-primary"
                         style="margin-top:5px" >
            <p:ajax process="formPickList"  />
        </p:commandButton>

The dialog is at the top of the XHTML outside this form and it has a form of its own embedded in the dialog along with a datatable which holds additional commands for streaming the media that all needed to be primed and ready to go when the dialog is presented. You can use this same technique to do things like download customized documents that need to be prepared before they are streamed to the user's computer via fileDownload buttons in the dialog box as well.

As I said, this is a more complicated example, but it hits all the high points of your problem and mine. When the command button is clicked, the result is to first insure the backing bean is updated with the results of the pickList, then tell the backing bean to prepare streams for the user based on their selections in the pick list, then update the controls in the dynamic dialog with an update, then show the dialog box ready for the user to start streaming their content.

The trick to it was to use BalusC's order of events for the main commandButton and then to add the <p:ajax process="formPickList" /> bit to ensure it was executed first - because nothing happens correctly unless the pickList updated the backing bean first (something that was not happening for me before I added it). So, yea, that commandButton rocks because you can affect previous, pending and current components as well as the backing beans - but the timing to interrelate all of them is not easy to get a handle on sometimes.

Happy coding!

This should do the work:

.category_table tr:first-child td {
    vertical-align: top;
}

What am I doing wrong?

$(...) holds the value, not the exit status, that is why this approach is wrong. However, in this specific case, it does indeed work because sysa will be printed which makes the test statement come true. However, if ! [ $(true) ]; then echo false; fi would always print false because the true command does not write anything to stdout (even though the exit code is 0). That is why it needs to be rephrased to if ! grep ...; then.

An alternative would be cat /etc/passwd | grep "sysa" || echo error. Edit: As Alex pointed out, cat is useless here: grep "sysa" /etc/passwd || echo error.

Found the other answers rather confusing, hope this helps someone.

I have a button for a prompt that on click it opens the display dialogue and then I can write what I want to search and it goes to that location on the page. It uses javascript to answer the header.

On the .html file I have:

<button onclick="myFunction()">Load Prompt</button>
<span id="test100"><h4>Hello</h4></span>

On the .js file I have

function myFunction() {
    var input = prompt("list or new or quit");

    while(input !== "quit") {
        if(input ==="test100") {
            window.location.hash = 'test100';
            return;
// else if(input.indexOf("test100") >= 0) {
//   window.location.hash = 'test100';
//   return;
// }
        }
    }
}

When I write test100 into the prompt, then it will go to where I have placed span id="test100" in the html file.

I use Google Chrome.

Note: This idea comes from linking on the same page using

<a href="#test100">Test link</a>

which on click will send to the anchor. For it to work multiple times, from experience need to reload the page.

Credit to the people at stackoverflow (and possibly stackexchange, too) can't remember how I gathered all the bits and pieces. ?

I ended up with the following:

set input=AAA BBB CCC DDD EEE FFF
set nth=4
for /F "tokens=%nth% delims= " %%a in ("%input%") do set nthstring=%%a
echo %nthstring%

With this you can parameterize the input and index. Make sure to put this code in a bat file.

Try this if you have only one Fragment

if (getSupportFragmentManager().getBackStackEntryCount() == 0) {
                    //TODO: Your Code Here
                }

try this, tested on windows platform and it works fine :

from selenium import webdriver
browser = webdriver.Chrome('C:\\Users\\yeivic\\Downloads\\chromedriver')
browser.fullscreen_window()
browser.get('http://google.com/')

One option that is available is fooTable. Works great on a Responsive website and allows you to set multiple breakpoints... fooTable Link

This works for me:

beforeShow: function(input, inst) {
    var $this = $(this);
    var cal = inst.dpDiv;
    var top = $this.offset().top + $this.outerHeight();
    var left = $this.offset().left;

    setTimeout(function() {
        cal.css({
            'top': top,
            'left': left
        });
    }, 10);
}

In addition to Juliano Nunes Silva Oliveira's answer, the simplest and most clean way without hacking into the regedit, removing hidden .git folders or changing your VS15 settings is by connecting to a different repository. When connected you see the text of the other repository bold then select your Git local repository. Now you see that the

Remove

menu item is enabled so you are able to delete your Git local repository.

It's the same type of behaviour when dealing with Branches when using Git with visual studio 2015. You need to select different branch before you can delete the branch you wan to delete.

For the ones who needs visualization to understand it better. see link image: how it's done

Happy coding

More recently, I have found that other factors will also cause this error. I had an AES.h, AES.cpp containing a AES class and it gave this same unhelpful error. Only when I renamed to Encryption.h, Encryption.cpp and Encryption as the class name did it suddenly start working. There were no other code changes.

I just want to propose another alternative that will concern some of you, indeed, as explained above:

android:configChanges="orientation|keyboardHidden" 

implies that we explicitly declare the layout to be injected.

In case we want to keep the automatic injection thanks to the layout-land and layout folders. All you have to do is add it to the onCreate:

    if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
        getSupportActionBar().hide();

    } else if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
        getSupportActionBar().show();
    }

Here, we display or not the actionbar depending on the orientation of the phone

You need to use a TimeSpan. Here is some sample code:

TimeSpan sincelast = TimeSpan.FromTicks(DateTime.Now.Ticks - LastUpdate.Ticks);

Just write:

min-height: xxx;
overflow: hidden;

then div will automatically take the height of the content.

Use this

var theForm = document.forms['formname']
[].slice.call(theForm).forEach(function (el, i) {
    console.log(el.value);
});

The el stands for the particular form element. It is better to use this than the foreach loop, as the foreach loop also returns a function as one of the element. However this only returns the DOM elements of the form.

It allows browsers to determine if they can handle the scripting/style language before making a request for the script or stylesheet (or, in the case of embedded script/style, identify which language is being used).

This would be much more important if there had been more competition among languages in browser space, but VBScript never made it beyond IE and PerlScript never made it beyond an IE specific plugin while JSSS was pretty rubbish to begin with.

The draft of HTML5 makes the attribute optional.

Swift 4.1

Add a func to viewDidLoad

override func viewDidLoad() {
  super.viewDidLoad()

  setup()
}   

In the setup() function add:

func setup() {

        navigationController?.navigationBar.prefersLargeTitles = true
        navigationController?.navigationBar.barStyle = .blackOpaque
        navigationItem.title = "YOUR_TITLE_HERE"
        navigationController?.navigationBar.barTintColor = .black
        let attributes = [NSAttributedStringKey.foregroundColor: UIColor.white]
        navigationController?.navigationBar.largeTitleTextAttributes = attributes
    }

As mentioned by BalusC, the border is set by PrimeFaces on the generated tr and td elements, not on the table. However when trying with PrimeFaces version 5, it looks like there is a more specific match from the PrimeFaces CSS .ui-panelgrid .ui-panelgrid-cell > solid which still result in black borders being shown when appyling the style suggested.

Try using following style in order to overide the Primefaces one without using the !important declaration:

.companyHeaderGrid tr, .companyHeaderGrid td.ui-panelgrid-cell {
    border: none;
}

As mention make sure your CSS is loaded after the PrimeFaces one.

Within your component, you can define an array of number (ES6) as described below:

export class SampleComponent {
  constructor() {
    this.numbers = Array(5).fill(0).map((x,i)=>i);
  }
}

See this link for the array creation: Tersest way to create an array of integers from 1..20 in JavaScript.

You can then iterate over this array with ngFor:

@View({
  template: `
    <ul>
      <li *ngFor="let number of numbers">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Or shortly:

@View({
  template: `
    <ul>
      <li *ngFor="let number of [0,1,2,3,4]">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Hope it helps you, Thierry

Edit: Fixed the fill statement and template syntax.

This is how you get a type string of your object or Type which is consistent and takes into account to which module the object definition belongs to or nested in. Works in Swift 4.x.

@inline(__always) func typeString(for _type: Any.Type) -> String {
    return String(reflecting: type(of: _type))
}

@inline(__always) func typeString(for object: Any) -> String {
    return String(reflecting: type(of: type(of: object)))
}

struct Lol {
    struct Kek {}
}

// if you run this in playground the results will be something like
typeString(for: Lol.self)    //    __lldb_expr_74.Lol.Type
typeString(for: Lol())       //    __lldb_expr_74.Lol.Type
typeString(for: Lol.Kek.self)//    __lldb_expr_74.Lol.Kek.Type
typeString(for: Lol.Kek())   //    __lldb_expr_74.Lol.Kek.Type

You will need to read the bytes from that File into a byte[] and put that object into your JSONObject.

You should also have a look at the following posts :

• ByteArray in JSON
• Binary Data in JSON String. Something better than Base64
• BSON library for java

Hope this helps.

Use an insert ... select query, and put the known values in the select:

insert into table1
select 'A string', 5, idTable2
from table2
where ...

In case, you want to keep old field (For ex: name). The query will be:

INSERT INTO table (id, name, age) VALUES(1, "A", 19) ON DUPLICATE KEY UPDATE    
name=name, age=19;

Below command for files.

scp `find . -maxdepth 1 -name "*.log" \! -name "hs_err_pid2801.log" -type f` root@IP:/tmp/test/

1. IP will be destination server IP address.
2. -name "*.log" for include files.
3. \! -name "hs_err_pid2801.log" for exclude files.
4. . is current working dir.
5. -type f for file type.

Below command for directory.

scp -r `find . -maxdepth 1 -name "lo*" \! -name "localhost" -type d` root@IP:/tmp/test/

you can customize above command as per your requirement.

So ... you need to change some things in your code

<form method="POST" id="form-pass">
Password: <input type="text" name="pwd" id="input-pwd">
<input type="submit" value="Submit">
</form>

<script>
var form = document.querySelector('#form-pass');
var pwd = document.querySelector('#input-pwd');
pwd.focus();
form.onsubmit = checkForm;

function checkForm() {
  alert(pwd.value);
}
</script>

Try this way.

For IntelliJ IDEA 2017.2 I did the following to fix this issue: Go to your project structure Now go to SDKs under platform settings and click the green add button. Add your JDK path. In my case it was this path C:\Program Files\Java\jdk1.8.0_144 Now Just go Project under Project settings and select the project SDK.

console.log( 'You are running jQuery version: ' + $.fn.jquery );

As far as I know, a forced update like this is not directly possible. You might be able to reduce the DNS downtime by reducing the TTL (Time-To-Live) value of the entries before changing them, if your name server service provider allows that.

Here's a guide for less painful DNS changes.

A fair warning, though - not all name servers between your client and the authoritative (origin) name server will enforce your TTL, they might have their own caching time.

Here's my timer for 5 minutes:

var start = moment("5:00", "m:ss");
var seconds = start.minutes() * 60;
this.interval = setInterval(() => {
    this.timerDisplay = start.subtract(1, "second").format("m:ss");
    seconds--;
    if (seconds === 0) clearInterval(this.interval);
}, 1000);

I think you should manage to store your data in a way that you will simply do a join and it will be perfect, so no hacks and complicated things going on.

I have for instance a "Recently played" list of track ids, on SQLite i simply do:

SELECT * FROM recently NATURAL JOIN tracks;

Once I designed an API which main resource was people. Usually users would request filtered people so, to prevent users to call something like /people?settlement=urban every time, I implemented /people/urban which later enabled me to easily add /people/rural. Also this allows to access the full /people list if it would be of any use later on. In short, my reasoning was to add a path to common subsets

From here:

Aliases for common queries

To make the API experience more pleasant for the average consumer, consider packaging up sets of conditions into easily accessible RESTful paths. For example, the recently closed tickets query above could be packaged up as GET /tickets/recently_closed

At some point in time the object changed from ionic to an uppercase Ionic.

As of July 2017 you need to put Ionic.version into your console to get the version number.

A simple definition would be an HTTP request that acts like a normal method call; i.e., it accepts parameters and returns a structured result, usually XML, that can be deserialized into an object(s).

These answers are totally my opinion

Answers

1. Picasso is an easy to use image loader, same goes for Imageloader. Fresco uses a different approach to image loading, i haven't used it yet but it looks too me more like a solution for getting image from network and caching them then showing the images. then the other way around like Picasso/Imageloader/Glide which to me are more Showing image on screen that also does getting images from network and caching them.

2. Glide tries to be somewhat interchangeable with Picasso.I think when they were created Picasso's mind set was follow HTTP spec's and let the server decide the caching policies and cache full sized and resize on demand. Glide is the same with following the HTTP spec but tries to have a smaller memory footprint by making some different assumptions like cache the resized images instead of the fullsized images, and show images with RGB_565 instead of RGB_8888. Both libraries offer full customization of the default settings.

3. As to which library is the best to use is really hard to say. Picasso, Glide and Imageloader are well respected and well tested libraries which all are easy to use with the default settings. Both Picasso and Glide require only 1 line of code to load an image and have a placeholder and error image. Customizing the behaviour also doesn't require that much work. Same goes for Imageloader which is also an older library then Picasso and Glide, however I haven't used it so can't say much about performance/memory usage/customizations but looking at the readme on github gives me the impression that it is also relatively easy to use and setup. So in choosing any of these 3 libraries you can't make the wrong decision, its more a matter of personal taste. For fresco my opinion is that its another facebook library so we have to see how that is going to work out for them, so far there track record isn't that good. Like the facebook SDK is still isn't officially released on mavenCentral I have not used to facebook sdk since sept 2014 and it seems they have put the first version online on mavenCentral in oct 2014. So it will take some time before we can get any good opinion about it.

4. between the 3 big name libraries I think there are no significant differences. The only one that stand out is fresco but that is because it has a different approach and is new and not battle tested.

You've specifically mentioned a "variable-length array" in your question, so neither of the existing two answers (as I write this) are quite right.

Java doesn't have any concept of a "variable-length array", but it does have Collections, which serve in this capacity. Any collection (technically any "Iterable", a supertype of Collections) can be looped over as simply as this:

Collection<Thing> things = ...;
for (Thing t : things) {
  System.out.println(t);
}

EDIT: it's possible I misunderstood what he meant by 'variable-length'. He might have just meant it's a fixed length but not every instance is the same fixed length. In which case the existing answers would be fine. I'm not sure what was meant.

Create a function and copy the code using winsock which is mentioned already by Software_Developer.

For Instance:

#ifdef _WIN32

// this is required only for windows

if (WSAStartup(MAKEWORD(2,2), &wsaData) != 0)
{

  //...

}

#endif

winsock code here

#ifdef _WIN32

WSACleanup();

#endif

Using System Preferences:

Step 1: Click the Apple icon (at the top left of the screen) and select System Preferences.

Step 2: Click Network.

Step 3: Select your network connection and then click Advanced.

Step 4: Select the TCP/IP tab and find your gateway IP address listed next to Router.

I guess this document might serve as a not so short introduction : n3055

The whole massacre began with the move semantics. Once we have expressions that can be moved and not copied, suddenly easy to grasp rules demanded distinction between expressions that can be moved, and in which direction.

From what I guess based on the draft, the r/l value distinction stays the same, only in the context of moving things get messy.

Are they needed? Probably not if we wish to forfeit the new features. But to allow better optimization we should probably embrace them.

Quoting n3055:

• An lvalue (so-called, historically, because lvalues could appear on the left-hand side of an assignment expression) designates a function or an object. [Example: If E is an expression of pointer type, then *E is an lvalue expression referring to the object or function to which E points. As another example, the result of calling a function whose return type is an lvalue reference is an lvalue.]
• An xvalue (an “eXpiring” value) also refers to an object, usually near the end of its lifetime (so that its resources may be moved, for example). An xvalue is the result of certain kinds of expressions involving rvalue references. [Example: The result of calling a function whose return type is an rvalue reference is an xvalue.]
• A glvalue (“generalized” lvalue) is an lvalue or an xvalue.
• An rvalue (so-called, historically, because rvalues could appear on the right-hand side of an assignment expression) is an xvalue, a temporary object or subobject thereof, or a value that is not associated with an object.
• A prvalue (“pure” rvalue) is an rvalue that is not an xvalue. [Example: The result of calling a function whose return type is not a reference is a prvalue]

The document in question is a great reference for this question, because it shows the exact changes in the standard that have happened as a result of the introduction of the new nomenclature.

A mask defines which bits you want to keep, and which bits you want to clear.

Masking is the act of applying a mask to a value. This is accomplished by doing:

• Bitwise ANDing in order to extract a subset of the bits in the value
• Bitwise ORing in order to set a subset of the bits in the value
• Bitwise XORing in order to toggle a subset of the bits in the value

Below is an example of extracting a subset of the bits in the value:

Mask:   00001111b
Value:  01010101b

Applying the mask to the value means that we want to clear the first (higher) 4 bits, and keep the last (lower) 4 bits. Thus we have extracted the lower 4 bits. The result is:

Mask:   00001111b
Value:  01010101b
Result: 00000101b

Masking is implemented using AND, so in C we get:

uint8_t stuff(...) {
  uint8_t mask = 0x0f;   // 00001111b
  uint8_t value = 0x55;  // 01010101b
  return mask & value;
}

Here is a fairly common use-case: Extracting individual bytes from a larger word. We define the high-order bits in the word as the first byte. We use two operators for this, &, and >> (shift right). This is how we can extract the four bytes from a 32-bit integer:

void more_stuff(uint32_t value) {             // Example value: 0x01020304
    uint32_t byte1 = (value >> 24);           // 0x01020304 >> 24 is 0x01 so
                                              // no masking is necessary
    uint32_t byte2 = (value >> 16) & 0xff;    // 0x01020304 >> 16 is 0x0102 so
                                              // we must mask to get 0x02
    uint32_t byte3 = (value >> 8)  & 0xff;    // 0x01020304 >> 8 is 0x010203 so
                                              // we must mask to get 0x03
    uint32_t byte4 = value & 0xff;            // here we only mask, no shifting
                                              // is necessary
    ...
}

Notice that you could switch the order of the operators above, you could first do the mask, then the shift. The results are the same, but now you would have to use a different mask:

uint32_t byte3 = (value & 0xff00) >> 8;

CharField has max_length of 255 characters while TextField can hold more than 255 characters. Use TextField when you have a large string as input. It is good to know that when the max_length parameter is passed into a TextField it passes the length validation to the TextArea widget.

SELECT productid FROM product WHERE purchase_date > sysdate-30

%08x means that every number should be printed at least 8 characters wide with filling all missing digits with zeros, e.g. for '1' output will be 00000001

The na.omit function is what a lot of the regression routines use internally:

vec <- 1:1000
vec[runif(200, 1, 1000)] <- NA
max(vec)
#[1] NA
max( na.omit(vec) )
#[1] 1000

I already had this same issue and I've got the solution writing a container (.divtagABS-container, in your case) absolutely positioned and then relatively positioning the content inside it (.divtagABS, in your case).

Done! The margin-left and margin-right AUTO for your .divtagABS will now work.

The first constructor in the header should not end with a semicolon. #include <string> is missing in the header. string is not qualified with std:: in the .cpp file. Those are all simple syntax errors. More importantly: you are not using references, when you should. Also the way you use the ifstream is broken. I suggest learning C++ before trying to use it.

Let's fix this up:

//polygone.h
# if !defined(__POLYGONE_H__)
# define __POLYGONE_H__

#include <iostream>
#include <string>    

class Polygone {
public:
  // declarations have to end with a semicolon, definitions do not
  Polygone(){} // why would we needs this?
  Polygone(const std::string& fichier);
};

# endif

and

//polygone.cc
// no need to include things twice
#include "polygone.h"
#include <fstream>


Polygone::Polygone(const std::string& nom)
{
  std::ifstream fichier (nom, ios::in);


  if (fichier.is_open())
  {
    // keep the scope as tiny as possible
    std::string line;
    // getline returns the stream and streams convert to booleans
    while ( std::getline(fichier, line) )
    {
      std::cout << line << std::endl;
    }
  }
  else
  {
    std::cerr << "Erreur a l'ouverture du fichier" << std::endl;
  }
}

I solved it using the LOCAL option in the command:

LOAD DATA LOCAL INFILE "text.txt" INTO TABLE mytable;

You can find more info here.

If LOCAL is specified, the file is read by the client program on the client host and sent to the server. The file can be given as a full path name to specify its exact location. If given as a relative path name, the name is interpreted relative to the directory in which the client program was started.

I don't know which version of MySQL you're using, but here are possible locations of the my.cnf file for version 5.5 (taken from here) on Mac OS X:

1. /etc/my.cnf
2. /etc/mysql/my.cnf
3. SYSCONFDIR/my.cnf
4. $MYSQL_HOME/my.cnf
5. defaults-extra-file (the file specified with --defaults-extra-file=path, if any)
6. ~/.my.cnf

In the page load event you set your label

lbl_username.text = "some text";

Firefox 26 seems to require

page-break-inside: avoid;

And Chrome 32 needs

-webkit-column-break-inside:avoid;
   -moz-column-break-inside:avoid;
        column-break-inside:avoid;

string s = "hello";
char c = s[1];
// now c == 'e'

See also Substring, to return more than one character.

I'm not sure what wget is, but to get a file from the web and store it locally, you can use NSData:

NSString *stringURL = @"http://www.somewhere.com/thefile.png";
NSURL  *url = [NSURL URLWithString:stringURL];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if ( urlData )
{
  NSArray       *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
  NSString  *documentsDirectory = [paths objectAtIndex:0];  

  NSString  *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"filename.png"];
  [urlData writeToFile:filePath atomically:YES];
}

Also make sure the user issuing the query has been granted the necessary permissions.

For queries on tables you need to grant SELECT permission.
For queries on other object types (e.g. stored procedures) you need to grant EXECUTE permission.

For me it only happened in one project and I tried everything I found online and nothing seemed to help. I was ready to delete and recreate the project when after messing through the projects properties changing the .NET framework target from 4.7.2 to 4.8 fixed the issue. I changed it back to 4.7.2 later and the error is gone.

Hopefully this helps other users as well.

Fetch id basing on name

 {
    "roles": [
     {
      "id": 1,
      "name": "admin",
     },
     {
      "id": 3,
      "name": "manager",
     }
    ]
    }



    fetchIdBasingOnRole() {
          const self = this;
          if (this.employee.roles) {
            var roleid = _.result(
              _.find(this.getRoles, function(obj) {
                return obj.name === self.employee.roles;
              }),
              "id"
            );
          }
          return roleid;
        },

In @dudusan's example, you could also reverse the order of I1, and then sort ascending:

> rum <- read.table(textConnection("P1  P2  P3  T1  T2  T3  I1  I2
+   2   3   5   52  43  61  6   b
+   6   4   3   72  NA  59  1   a
+   1   5   6   55  48  60  6   f
+   2   4   4   65  64  58  2   b
+   1   5   6   55  48  60  6   c"), header = TRUE)
> f=factor(rum$I1)   
> levels(f) <- sort(levels(f), decreasing = TRUE)
> rum[order(as.character(f), rum$I2), ]
  P1 P2 P3 T1 T2 T3 I1 I2
1  2  3  5 52 43 61  6  b
5  1  5  6 55 48 60  6  c
3  1  5  6 55 48 60  6  f
4  2  4  4 65 64 58  2  b
2  6  4  3 72 NA 59  1  a
> 

This seems a bit shorter, you don't reverse the order of I2 twice.

This prints the key combination directly to the image:

The first window shows 'z' pressed, the second shows 'ctrl' + 'z' pressed. When a key combination is used, a question mark appear.

Don't mess up with the question mark code, which is 63.

import numpy as np
import cv2

im = np.zeros((100, 300), np.uint8)
cv2.imshow('Keypressed', im)
while True:
  key = cv2.waitKey(0)
  im_c = im.copy()
  cv2.putText(
    im_c,
    f'{chr(key)} -> {key}',
    (10, 60), 
    cv2.FONT_HERSHEY_SIMPLEX, 
    1,
    (255,255,255),
    2)
  cv2.imshow('Keypressed', im_c)
  if key == 27: break # 'ESC'

You can use:

UPDATE s SET
  s.Field1 = q.Field1,
  s.Field2 = q.Field2,
  (list of fields...)
FROM (
  SELECT Field1, Field2, (list of fields...)
  FROM ProfilerTest.dbo.BookingDetails 
  WHERE MyID=@MyID
) q
WHERE s.MyID2=@ MyID2

create a bash script with the following:

#!/bin/bash
exec ./manage.py runserver 0.0.0.0:<your_port>

save it as runserver in the same dir as manage.py

chmod +x runserver

and run it as

./runserver

I think this should work:

#include <time.h>

clock_t start = clock(), diff;
ProcessIntenseFunction();
diff = clock() - start;

int msec = diff * 1000 / CLOCKS_PER_SEC;
printf("Time taken %d seconds %d milliseconds", msec/1000, msec%1000);

In addition to previous answers there is one important for me note:

shelve is JetBrains products feature (such as WebStorm, PhpStorm, PyCharm, etc.). It puts shelved files into .idea/shelf directory.

stash is one of git options. It puts stashed files under the .git directory.

I had the same problem and found two different solutions (see this thread for more details). Both reduced the size of my uncompressed PDF dramatically.

• Pixelated (lossy):

  convert input.pdf -compress Zip output.pdf
  

• Unpixelated (lossless, but may display slightly differently):

  gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen -dNOPAUSE -dBATCH  -dQUIET -sOutputFile=output.pdf input.pdf
  

Edit: I just discovered another option (for lossless compression), which avoids the nasty gs command. qpdf is a neat tool that converts PDFs (compression/decompression, encryption/decryption), and is much faster than the gs command:

qpdf --linearize input.pdf output.pdf

Oracle's security model is such that when executing dynamic SQL using Execute Immediate (inside the context of a PL/SQL block or procedure), the user does not have privileges to objects or commands that are granted via role membership. Your user likely has "DBA" role or something similar. You must explicitly grant "drop table" permissions to this user. The same would apply if you were trying to select from tables in another schema (such as sys or system) - you would need to grant explicit SELECT privileges on that table to this user.

Collection literals didn't make it into Java 8, but it is possible to use the Stream API to initialize a list in one rather long line:

List<String> places = Stream.of("Buenos Aires", "Córdoba", "La Plata").collect(Collectors.toList());

If you need to ensure that your List is an ArrayList:

ArrayList<String> places = Stream.of("Buenos Aires", "Córdoba", "La Plata").collect(Collectors.toCollection(ArrayList::new));

The jsqrcode library by Lazarsoft is now working perfectly using just HTML5, i.e. getUserMedia (WebRTC). You can find it on GitHub.

I also found a great fork which is much simplified. Just one file (plus jQuery) and one call of a method: see html5-qrcode on GitHub.

You can't commit empty folders in git. If you want it to show up, you need to put something in it, even just an empty file.

For example, add an empty file called .gitkeep to the folder you want to keep, then in your .gitignore file write:

# exclude everything
somefolder/*

# exception to the rule
!somefolder/.gitkeep 

Commit your .gitignore and .gitkeep files and this should resolve your issue.

For Spyder 2.3 which is still installed via apt-get on linux, you change the theme via

Tools > Preferences > Editor > Syntax Color 

The

Tools > Preferences > Syntax Coloring

only shows options for adjusting the different themes, but not actually applying a different theme. Spyder 3.x uses the second option via Syntax Color.

Just add the seen attribute to redirect tag as below:

<redirect include-view-params="true">
    <view-param>
        <name>id</name>
        <value>#{myBean.id}</value>
    </view-param>
</redirect>

Change it for

$results->fetch_array()

I have this to simply rename all files in subfolders of folder

import os

def replace(fpath, old_str, new_str):
    for path, subdirs, files in os.walk(fpath):
        for name in files:
            if(old_str.lower() in name.lower()):
                os.rename(os.path.join(path,name), os.path.join(path,
                                            name.lower().replace(old_str,new_str)))

I am replacing all occurences of old_str with any case by new_str.

Solved using JavaScript + jQuery! I just need similar solution to my project but current solution with HTML and CSS is not ok for me because there is issue with column height + I need more then one column to be fixed. So I create simple javascript solution using jQuery

You can try it here https://jsfiddle.net/kindrosker/ffwqvntj/

All you need is setup home many columsn will be fixed in data-count-fixed-columns parameter

<table class="table" data-count-fixed-columns="2" cellpadding="0" cellspacing="0">

and run js function

app_handle_listing_horisontal_scroll($('#table-listing'))

You may use Directory Functions: http://php.net/manual/en/book.dir.php

Simple example from opendir() function description:

<?php
$dir_path = "/path/to/your/dir";

if (is_dir($dir_path)) {
    if ($dir_handler = opendir($dir_path)) {
        while (($file = readdir($dir_handler)) !== false) {
            echo "filename: $file : filetype: " . filetype($dir_path . $file) . "\n";
        }
        closedir($dir_handler);
    }
}
?>

Just for completeness and those unaware XSL 1 has choose for multiple conditions.

<xsl:choose>
 <xsl:when test="expression">
  ... some output ...
 </xsl:when>
 <xsl:when test="another-expression">
  ... some output ...
 </xsl:when>
 <xsl:otherwise>
   ... some output ....
 </xsl:otherwise>
</xsl:choose>

Make sure you fill in your domain name and it must not end with a path.

example

http://yourdomain.com (good)

http://yourdomain.com/folder (error)

Ahhhh, now it is clear. You seem to have problems binding back the value. Not with displaying it on the view. Indeed, that's the fault of the default model binder. You could write and use a custom one that will take into consideration the [DisplayFormat] attribute on your model. I have illustrated such a custom model binder here: https://stackoverflow.com/a/7836093/29407

Apparently some problems still persist. Here's my full setup working perfectly fine on both ASP.NET MVC 3 & 4 RC.

Model:

public class MyViewModel
{
    [DisplayName("date of birth")]
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
    public DateTime? Birth { get; set; }
}

Controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel
        {
            Birth = DateTime.Now
        });
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        return View(model);
    }
}

View:

@model MyViewModel

@using (Html.BeginForm())
{
    @Html.LabelFor(x => x.Birth)
    @Html.EditorFor(x => x.Birth)
    @Html.ValidationMessageFor(x => x.Birth)
    <button type="submit">OK</button>
}

Registration of the custom model binder in Application_Start:

ModelBinders.Binders.Add(typeof(DateTime?), new MyDateTimeModelBinder());

And the custom model binder itself:

public class MyDateTimeModelBinder : DefaultModelBinder
{
    public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
        var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

        if (!string.IsNullOrEmpty(displayFormat) && value != null)
        {
            DateTime date;
            displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
            // use the format specified in the DisplayFormat attribute to parse the date
            if (DateTime.TryParseExact(value.AttemptedValue, displayFormat, CultureInfo.InvariantCulture, DateTimeStyles.None, out date))
            {
                return date;
            }
            else
            {
                bindingContext.ModelState.AddModelError(
                    bindingContext.ModelName,
                    string.Format("{0} is an invalid date format", value.AttemptedValue)
                );
            }
        }

        return base.BindModel(controllerContext, bindingContext);
    }
}

Now, no matter what culture you have setup in your web.config (<globalization> element) or the current thread culture, the custom model binder will use the DisplayFormat attribute's date format when parsing nullable dates.

It is a unicode char \u003C = <

You need to have the private key of the signing certificate in the keychain along with the public key. Have you created the certificate using the same Mac (keychain) ?

Solution #1:

• Revoke the signing certificate (reset) from apple developer portal
• Create the signing certificate again on the same mac (keychain). Then you will have the private key for the signing certificate!

Solution #2:

• Export the signing identities from the origin xCode
• Import the signing on your xCode

This problem happens because IIS does not know about woff and woff2 file mime types.

Solution 1:

Add these lines in your web.config project:

 <system.webServer>
  ...
  </modules>
    <staticContent>
      <remove fileExtension=".woff" />
      <mimeMap fileExtension=".woff" mimeType="application/font-woff" />
      <remove fileExtension=".woff2" />
      <mimeMap fileExtension=".woff2" mimeType="font/woff2" />
    </staticContent>

Solution 2:

On IIS project page:

Step 1: Go to your project IIS home page and double click on MIME Types button:

Step 2: Click on Add button from Actions menu:

Step 3: In the middle of the screen appears a window and in this window you need to add the two lines from solution 1:

Some SelectMany may not be necessary. Below 2 queries give the same result.

Customers.Where(c=>c.Name=="Tom").SelectMany(c=>c.Orders)

Orders.Where(o=>o.Customer.Name=="Tom")

For 1-to-Many relationship,

1. if Start from "1", SelectMany is needed, it flattens the many.
2. if Start from "Many", SelectMany is not needed. (still be able to filter from "1", also this is simpler than below standard join query)

from o in Orders
join c in Customers on o.CustomerID equals c.ID
where c.Name == "Tom"
select o

The safest way would be bitwise OR ing your double with 0. Look at this XORing two doubles in Java

Basically you should do if ((Double.doubleToRawLongBits(foo.x) | 0 ) ) (if it is really 0)

Try this.This works while traversing the code and modifying the fields at once of all the elements of Arraylist.

public Employee(String name,String email){
this.name=name;
this.email=email;
}

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

public String getName() {
return name;
}

public void setEmail(String email) {
this.email = email;
}

public String getEmail() {
return email;
}

for(int i=0;i++){
List.get(i).setName("Anonymous");
List.get(i).setEmail("[email protected]");
}

Easy Way

Add usesCleartextTraffic to AndroidManifest.xml

<application
...
android:usesCleartextTraffic="true"
...>

Indicates whether the app intends to use cleartext network traffic, such as cleartext HTTP. The default value for apps that target API level 27 or lower is "true". Apps that target API level 28 or higher default to "false".

In Python 3, you can use the builtin range function like this

>>> list(range(9))
[0, 1, 2, 3, 4, 5, 6, 7, 8]

Note 1: Python 3.x's range function, returns a range object. If you want a list you need to explicitly convert that to a list, with the list function like I have shown in the answer.

Note 2: We pass number 9 to range function because, range function will generate numbers till the given number but not including the number. So, we give the actual number + 1.

Note 3: There is a small difference in functionality of range in Python 2 and 3. You can read more about that in this answer.

IndexError: invalid index to scalar variable happens when you try to index a numpy scalar such as numpy.int64 or numpy.float64. It is very similar to TypeError: 'int' object has no attribute '__getitem__' when you try to index an int.

>>> a = np.int64(5)
>>> type(a)
<type 'numpy.int64'>
>>> a[3]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: invalid index to scalar variable.
>>> a = 5
>>> type(a)
<type 'int'>
>>> a[3]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object has no attribute '__getitem__'

You can use a library called underscore js. It gives a nice wrapper on the bind method and is a much cleaner syntax as well. Letting you execute the function in the specified scope.

http://underscorejs.org/#bind

_.bind(function, scope, *arguments)

If you're using the close class in your modals, the following will work. Depending on your use case, I generally recommend filtering to only the visible modal if there are more than one modals with the close class.

$('.close:visible').click();

I'm using

$("input:radio[name='html_radio']").is(":checked")

And will return FALSE if all the items in the radiogroup are unchecked and TRUE if an item is checked.
