I had the same problem. Make sure you include assembly name in Factory property in your .svc file. Maybe you need to clean IIS cache if you had renamed project assembly name.

In Windows Vista and later the HTTP WCF service stuff would cause the exception you mentioned because a restricted account does not have right for that. That is the reason why it worked when you ran it as administrator.

Every sensible developer must use a RESTRICTED account rather than as an Administrator, yet many people go the wrong way and that is precisely why there are so many applications out there that DEMAND admin permissions when they are not really required. Working the lazy way results in lazy solutions. I hope you still work in a restricted account (my congratulations).

There is a tool out there (from 2008 or so) called NamespaceManagerTool if I remember correctly that is supposed to grant the restricted user permissions on these service URLs that you define for WCF. I haven't used that though...

DataMember attribute is not mandatory to add to serialize data. When DataMember attribute is not added, old XMLSerializer serializes the data. Adding a DataMember provides useful properties like order, name, isrequired which cannot be used otherwise.

I faced the same problem, and resolved it by changing the BodyStyle attribut value to "WebMessageBodyStyle.Bare" :

[OperationContract]
[WebGet(BodyStyle = WebMessageBodyStyle.Bare, RequestFormat = WebMessageFormat.Json,
        ResponseFormat = WebMessageFormat.Json, UriTemplate = "GetProjectWithGeocodings/{projectId}")]
GeoCod_Project GetProjectWithGeocodings(string projectId);

The returned object will no longer be wrapped.

I had this error too , and finally this codes worked for me in dot net core 3.1

first install svcutil in command prompt : dotnet tool install --global dotnet-svcutil

Then close command prompt and open it again.

Then create the Reference.cs in command prompt :

dotnet-svcutil http://YourService.com/SayHello.svc

(It needs an enter key and UserName and Password)

Add a folder named Connected Services to project root.

Copy Reference.cs file to Connected Services folder.

Add these 4 lines to Reference.cs after lines where creating BasicHttpBinding and setting MaxBufferSize :

result.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
result.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
result.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;
result.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;

Use this service in your Controller :

public async Task<string> Get()
    {
        try
        {
            var client = new EstelamClient();
            client.ClientCredentials.UserName.UserName = "YourUserName";
            client.ClientCredentials.UserName.Password = "YourPassword";
            var res = await client.EmployeeCheckAsync("service parameters");
            return res.ToString();
        }
        catch (Exception ex)
        {
            return ex.Message + " ************ stack : " + ex.StackTrace;
        }

    }

Do not forget install these packages in .cshtml :

<PackageReference Include="System.ServiceModel.Duplex" Version="4.6.*" />
<PackageReference Include="System.ServiceModel.Http" Version="4.6.*" />
<PackageReference Include="System.ServiceModel.NetTcp" Version="4.6.*" />
<PackageReference Include="System.ServiceModel.Security" Version="4.6.*" />

I ran into this exact same issue today. I had installed IIS, but did not have the activate WCF Services Enabled under .net framework 4.6.

File format
This tool parses .CRX version 2 format documented by Google. In general, .CRX file format consist of few parts:

Magic header
Version of file format
Public Key information and a package signature Zipped contents of the extension source code Magic header is a signature of the file telling that this file is Chrome Extension. Using this header the operating system can determine the actual type of the file (MIME type is application/x-chrome-extension), and how should it be treaten (is it executable? is it a text file?). Then the window system can show beautiful icon to the user.

In .CRX files the magic header has a constant value Cr24 or 0x43723234.

The version is provided by vendor. The version bytes are 0x02000000.

The next part of the file contains the length of the public key information and the length of a digital signature.

All .CRX packages distributed via Chrome WebStore should have public key information and digital signature in order to make possible for browser to check that the package has been transmitted without modifications and that no additions or replacements were made.

After all of the header stuff, typically ending up on 307'th byte, comes the code of extension, stored as zip-archive. So the remainder of the .crx file is the well-known .zip archive.

.crx file opened in the hex editor called HexFiend (on Mac) The header part of a .crx file selected on the picture above. Obviously, you can extract the remaining .zip archive "by hand" using any simple hex editor. In this example, we use handy HexFiend editor on Mac.

The CRX Extractor loads a file provided, checks a magic header, version and trims the file, so only .zip archive remains. Then it returns obtained .zip archive to user.

Finally I have found a solution to get random and unique values.

My solution is:

substr(md5(time()), 0, 12)

time always return a timestamp, and it is always unique. You can use it with MD5 to make it better.

Try the JSON Parser by Douglas Crockford at github. You can then simply create a JSON object out of your String variable as shown below:

var JSONText = '{"c":{"a":[{"name":"cable - black","value":2},{"name":"case","value":2}]},"o":{"v":[{"name":"over the ear headphones - white/purple","value":1}]},"l":{"e":[{"name":"lens cleaner","value":1}]},"h":{"d":[{"name":"hdmi cable","value":1},{"name":"hdtv essentials (hdtv cable setup)","value":1},{"name":"hd dvd \u0026 blue-ray disc lens cleaner","value":1}]}'

var JSONObject = JSON.parse(JSONText);
var c = JSONObject["c"];
var o = JSONObject["o"];

Sometimes, it may help switching off AllowAutoRedirect and setting both login POST and page GET requests the same user agent.

request.UserAgent = userAgent;
request.AllowAutoRedirect = false;

$db  = new PDO('mysql:host=localhost;dbname=java_db', 'root', 'pass');
$Sql = "SELECT count(*) as `total` FROM users";
$stmt = $db->query($Sql);
$stmt->execute();
$total = $stmt->fetch(PDO::FETCH_ASSOC);
print '<pre>';
print_r($total);
print '</pre>';

Result:

I hope my script help you.

<i class="mostrar-producto">mostrar...</i>
<div class="producto" style="display:none;position: absolute;">Producto</div>

My script

<script>
$(".mostrar-producto").mouseover(function(){
     $(".producto").fadeIn();
 });

 $(".mostrar-producto").mouseleave(function(){
      $(".producto").fadeOut();
  });
</script>

var fd = new FormData();
var file_data = $('input[type="file"]')[0].files; // for multiple files
for(var i = 0;i<file_data.length;i++){
    fd.append("file_"+i, file_data[i]);
}
var other_data = $('form').serializeArray();
$.each(other_data,function(key,input){
    fd.append(input.name,input.value);
});
$.ajax({
    url: 'test.php',
    data: fd,
    contentType: false,
    processData: false,
    type: 'POST',
    success: function(data){
        console.log(data);
    }
});

Added a for loop and changed .serialize() to .serializeArray() for object reference in a .each() to append to the FormData.

Since most of the ansswers seem to be outdated here is the setting that worked for me:

• Elasticsearch-Version: 7.2.0 (OSS) running on Docker
• Java-Version: JDK-11

elasticsearch.yml:

cluster.name: production
node.name: node1
network.host: 0.0.0.0
transport.tcp.port: 9300
cluster.initial_master_nodes: node1

Setup:

client = new PreBuiltTransportClient(Settings.builder().put("cluster.name", "production").build());
client.addTransportAddress(new TransportAddress(InetAddress.getByName("localhost"), 9300));

Since PreBuiltTransportClient is deprecated you should use RestHighLevelClient for Elasticsearch-Version 7.3.0: https://artifacts.elastic.co/javadoc/org/elasticsearch/client/elasticsearch-rest-high-level-client/7.3.0/index.html

I got the same issue. To solve the issue you need to update your PHP version.

You can use the following to get the previous URL.

var oldURL = document.referrer;
alert(oldURL);

As I found by the previous answers, three steps are needed to change the type of a column:

Step 1:

Generate a new migration file using this code:

rails g migration sample_name_change_column_type

Step 2:

Go to /db/migrate folder and edit the migration file you made. There are two different solutions.

1. def change
       change_column(:table_name, :column_name, :new_type)
   end
   

2.

    def up
        change_column :table_name, :column_name, :new_type
    end

    def down
        change_column :table_name, :column_name, :old_type
    end

Step 3:

Don't forget to do this command:

rake db:migrate

I have tested this solution for Rails 4 and it works well.

You simply can find a matrix dimension by using Numpy:

import numpy as np

x = np.arange(24).reshape((6, 4))
x.ndim

output will be:

2

It means this matrix is a 2 dimensional matrix.

x.shape

Will show you the size of each dimension. The shape for x is equal to:

(6, 4)

Change hibernate.cfg.xml to:

<property name="show_sql">true</property>
<property name="format_sql">true</property>
<property name="use_sql_comments">true</property>

Include log4j and below entries in "log4j.properties":

log4j.logger.org.hibernate=INFO, hb
log4j.logger.org.hibernate.SQL=DEBUG
log4j.logger.org.hibernate.type=TRACE

log4j.appender.hb=org.apache.log4j.ConsoleAppender
log4j.appender.hb.layout=org.apache.log4j.PatternLayout

Just Make it transparent, and no action while pressend

AppBar(
            leading: IconButton(
              icon: Icon(
                Icons.arrow_back,
                color: Colors.white.withOpacity(0),
              ),
              onPressed: () {},
            ),

Textbox.Focus() "Tries" to set focus on the textbox element. In case of the element visibility is hidden for example, Focus() will not work. So make sure that your element is visible before calling Focus().

You may use this following code actually it is rough but plz check it out

db = openOrCreateDatabase("sms.db", SQLiteDatabase.CREATE_IF_NECESSARY, null);
Cursor cc = db.rawQuery("SELECT * FROM datatable", null);
final ArrayList<String> row1 = new ArrayList<String>();
final ArrayList<String> row2 = new ArrayList<String>();

if(cc!=null) {
    cc.moveToFirst();   
    startManagingCursor(cc);
    for (int i=0; i<cc.getCount(); i++) {

    String number  = cc.getString(0);
    String message = cc.getString(1);
    row1.add(number);
    row2.add(message);

    final EditText et3 = (EditText) findViewById(R.id.editText3);
    final EditText et4 = (EditText) findViewById(R.id.editText4);
    Button bt1 = (Button) findViewById(R.id.button1);
    bt1.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            switch (v.getId()) {
                case R.id.button1:
                    et3.setText(row1.get(count));
                    et4.setText(row2.get(count));
                    count++;
                    break;
                default:
                    break;
            }

        }
    });

cc.moveToNext();
}

You can do it without setlocal, because of the setlocal command the variable won't survive an endlocal because it was created in setlocal. In this way the variable will be defined the right way.

To do that use this code:

set var1=A

set var2=B

set AB=hi

call set newvar=%%%var1%%var2%%%

echo %newvar% 

Note: You MUST use call before you set the variable or it won't work.

Another faster way of downloading a GitHub project would be to use the clone functionality with the --depth argument as:

git clone --depth=1 [email protected]:organization/your-repo.git

to perform a shallow clone.

in jQuery:

$("#strings").val(["Test", "Prof", "Off"]);

or in pure JavaScript:

var element = document.getElementById('strings');
var values = ["Test", "Prof", "Off"];
for (var i = 0; i < element.options.length; i++) {
    element.options[i].selected = values.indexOf(element.options[i].value) >= 0;
}

jQuery does significant abstraction here.

I done in this way

from keras.models import Sequential
from keras_contrib.losses import import crf_loss
from keras_contrib.metrics import crf_viterbi_accuracy

# To save model
model.save('my_model_01.hdf5')

# To load the model
custom_objects={'CRF': CRF,'crf_loss': crf_loss,'crf_viterbi_accuracy':crf_viterbi_accuracy}

# To load a persisted model that uses the CRF layer 
model1 = load_model("/home/abc/my_model_01.hdf5", custom_objects = custom_objects)

BEGIN
  FOR r IN (select sid,serial# from v$session where username='user')
  LOOP
      EXECUTE IMMEDIATE 'alter system kill session ''' || r.sid  || ',' 
        || r.serial# || ''' immediate';
  END LOOP;
END;

This should work - I just changed your script to add the immediate keyword. As the previous answers pointed out, the kill session only marks the sessions for killing; it does not do so immediately but later when convenient.

From your question, it seemed you are expecting to see the result immediately. So immediate keyword is used to force this.

from datetime import date

def calculate_age(born):
    today = date.today()
    try: 
        birthday = born.replace(year=today.year)
    except ValueError: # raised when birth date is February 29 and the current year is not a leap year
        birthday = born.replace(year=today.year, month=born.month+1, day=1)
    if birthday > today:
        return today.year - born.year - 1
    else:
        return today.year - born.year

Update: Use Danny's solution, it's better

I put the resolution and fix for my issue . Looks like AJAX request that I put inside my JavaScript was not processing because my page was having some cache problem. if your site or page has a caching problem you will not see that problem in developers/F12 mode. my cached JavaScript AJAX requests it may not work as expected and cause the execution to break which F12 has no problem at all. So just added new parameter to make cache false.

$.ajax({
  cache: false,
});

Looks like IE specifically needs this to be false so that the AJAX and javascript activity run well.

Try this in MVC 4.0

@Html.TextBoxFor(m => m.YourDate, "{0:dd/MM/yyyy}", new { @class = "datefield form-control", @placeholder = "Enter start date..." })

Just turn the LIKE around

SELECT * FROM customers
WHERE 'Robert Bob Smith III, PhD.' LIKE CONCAT('%',name,'%')

Yes, the best practice is to check-in (YES, CHECK-IN)

I agree that it will cause a lot of noise or conflict when seeing the diff. But the benefits are:

1. guarantee exact same version of every package. This part is the most important when building in different environments at different times. You may use ^1.2.3 in your package.json, but how can u ensure each time npm install will pick up the same version in your dev machine and in the build server, especially those indirect dependency packages? Well, package-lock.json will ensure that. (With the help of npm ci which installs packages based on lock file)
2. it improves the installation process.
3. it helps with new audit feature npm audit fix (I think the audit feature is from npm version 6).

Getting the Original Dimensions of the Image

If you need to get the original image dimensions (not in the browser context), clientWidth and clientHeight properties do not work since they return incorrect values if the image is stretched/shrunk via css.

To get original image dimensions, use naturalHeight and naturalWidth properties.

var img = document.getElementById('imageId'); 

var width = img.naturalWidth;
var height = img.naturalHeight;

p.s. This does not answer the original question as the accepted answer does the job. This, instead, serves like addition to it.

<br> and <br/> render differently. Some browsers interpret <br/> as <br></br> and insert two line breaks

The information you want can be found by running

mysql --help

or

mysqld --help --verbose

I tried this command on my machine:

mysql --help | grep "Default options" -A 1

And it printed out:

Default options are read from the following files in the given order:
/etc/my.cnf /usr/local/etc/my.cnf ~/.my.cnf

See if that works for you.

I'd strongly recommend to keep working with swap files (in case Vim crashes).

You can set the directory where the swap files are stored, so they don't clutter your normal directories:

set swapfile
set dir=~/tmp

See also

:help swap-file

Beware the leading 00 that can appear in the modulus when using:

openssl rsa -pubin -inform PEM -text -noout < public.key

The example modulus contains 257 bytes rather than 256 bytes because of that 00, which is included because the 9 in 98 looks like a negative signed number.

I have at least one situation where the data is not automatically cleaned up, which would eventually lead to "Out of Memory" errors. In a UserForm I had:

Public mainPicture As StdPicture
...
mainPicture = LoadPicture(PAGE_FILE)

When UserForm was destroyed (after Unload Me) the memory allocated for the data loaded in the mainPicture was not being de-allocated. I had to add an explicit

mainPicture = Nothing

in the terminate event.

Better late than never, they always say.

Normally I'd use jQuery to solve such a situation. However, when working on a site for a client which required a javascript-less solution, I came up with the following:

<div class="hover-container">
    <div class="hover-content">
        <p>Content with<br />
        normal formatting</p>
    </div>
</div>

By using the following css, you get the same situation as with a title:

.hover-container {
    position: relative;
}

.hover-content {
    position: absolute;
    bottom: -10px;
    right: 10px;
    display: none;
}

.hover-container:hover .hover-content {
    display: block;
}

This gives you the option to style it according to your needs as well, and it works in all browsers. Even the ones where javascript is disabled.

Pros:

• You have a lot of influence on the styling
• It works in (nearly) all browsers

Cons:

• It's harder to position the tooltip

To see all tables in another schema, you need to have one or more of the following system privileges:

SELECT ANY DICTIONARY
(SELECT | INSERT | UPDATE | DELETE) ANY TABLE

or the big-hammer, the DBA role.

With any of those, you can select:

SELECT DISTINCT OWNER, OBJECT_NAME 
  FROM DBA_OBJECTS
 WHERE OBJECT_TYPE = 'TABLE'
   AND OWNER = '[some other schema]'

Without those system privileges, you can only see tables you have been granted some level of access to, whether directly or through a role.

SELECT DISTINCT OWNER, OBJECT_NAME 
  FROM ALL_OBJECTS
 WHERE OBJECT_TYPE = 'TABLE'
   AND OWNER = '[some other schema]'

Lastly, you can always query the data dictionary for your own tables, as your rights to your tables cannot be revoked (as of 10g):

SELECT DISTINCT OBJECT_NAME 
  FROM USER_OBJECTS
 WHERE OBJECT_TYPE = 'TABLE'

Or if you want a ripple pulse effect, you could use this:

    50% {opacity: 1.0;}
    100% {-webkit-transform: scale(1.2, 1.2); opacity: 0.0;}
}

You could also try setting style inline without using a variable, like so:

style={{"height" : "100%"}} or,

for multiple attributes: style={{"height" : "100%", "width" : "50%"}}

This seems to work for me:

LANG=C grep --only-matching --byte-offset --binary --text --perl-regexp "<\x-hex pattern>" <file>

short form:

LANG=C grep -obUaP "<\x-hex pattern>" <file>

Example:

LANG=C grep -obUaP "\x01\x02" /bin/grep

Output (cygwin binary):

153: <\x01\x02>
33210: <\x01\x02>
53453: <\x01\x02>

So you can grep this again to extract offsets. But don't forget to use binary mode again.

Note: LANG=C is needed to avoid utf8 encoding issues.

import urllib, urllib2, cookielib

username = 'myuser'
password = 'mypassword'

cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
login_data = urllib.urlencode({'username' : username, 'j_password' : password})
opener.open('http://www.example.com/login.php', login_data)
resp = opener.open('http://www.example.com/hiddenpage.php')
print resp.read()

resp.read() is the straight html of the page you want to open, and you can use opener to view any page using your session cookie.

Given the answer hardartcore that worked for me with a small change and did not work before the change:

private Handler mHandler = new Handler();
MusicPlayer.this.runOnUiThread(new Runnable() {
     @Override
     public void run() {
          if(player != null){
               int mCurrentPosition = player.getCurrentPosition();//clear ' /1000 '
               seekBar.setProgress(mCurrentPosition);
          }
          mHandler.postDelayed(this, 1000);
      }
});



seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {

    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {

    }

    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {

    }

    @Override
    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
          if(player != null && fromUser){
              player.seekTo(progress); // clear ' * 1000  '
          }
     }
});

Other than calling gmdate you can also put this code before your rest of the code:

<?php
date_default_timezone_set("UTC");
?>

That will make rest of your date/time related calls to use GMT/UTC timezone.

Note that if you use SELECT FOR UPDATE to perform a uniqueness check before an insert, you will get a deadlock for every race condition unless you enable the innodb_locks_unsafe_for_binlog option. A deadlock-free method to check uniqueness is to blindly insert a row into a table with a unique index using INSERT IGNORE, then to check the affected row count.

add below line to my.cnf file

innodb_locks_unsafe_for_binlog = 1

1 - ON
0 - OFF

If you use the string literal exactly as you have shown us, the problem is the ; character at the end. You may not include that in the query string in the JDBC calls.

As you are inserting only a single row, a regular INSERT should be just fine even when inserting multiple rows. Using a batched statement is probable more efficient anywy. No need for INSERT ALL. Additionally you don't need the temporary clob and all that. You can simplify your method to something like this (assuming I got the parameters right):

String query1 = "select substr(to_char(max_data),1,4) as year, " + 
  "substr(to_char(max_data),5,6) as month, max_data " +
  "from dss_fin_user.acq_dashboard_src_load_success " + 
  "where source = 'CHQ PeopleSoft FS'";

String query2 = ".....";

String sql = "insert into domo_queries (clob_column) values (?)";
PreparedStatement pstmt = con.prepareStatement(sql);
StringReader reader = new StringReader(query1);
pstmt.setCharacterStream(1, reader, query1.length());
pstmt.addBatch();

reader = new StringReader(query2);
pstmt.setCharacterStream(1, reader, query2.length());
pstmt.addBatch();

pstmt.executeBatch();   
con.commit();

Include a class example with the use keyword from Command Line Interface:

PHP Namespaces don't work on the commandline unless you also include or require the php file. When the php file is sitting in the webspace where it is interpreted by the php daemon then you don't need the require line. All you need is the 'use' line.

1. Create a new directory /home/el/bin

2. Make a new file called namespace_example.php and put this code in there:

   <?php
       require '/home/el/bin/mylib.php';
       use foobarwhatever\dingdong\penguinclass;
   
       $mypenguin = new penguinclass();
       echo $mypenguin->msg();
   ?>
   

3. Make another file called mylib.php and put this code in there:

   <?php
   namespace foobarwhatever\dingdong;
   class penguinclass 
   {
       public function msg() {
           return "It's a beautiful day chris, come out and play! " . 
                  "NO!  *SLAM!*  taka taka taka taka."; 
       }   
   }
   ?>   
   

4. Run it from commandline like this:

   el@apollo:~/bin$ php namespace_example.php 
   

5. Which prints:

   It's a beautiful day chris, come out and play!
   NO!  *SLAM!*  taka taka taka taka
   

See notes on this in the comments here: http://php.net/manual/en/language.namespaces.importing.php

Using the Node.js readline module.

var fs = require('fs');
var readline = require('readline');

var filename = process.argv[2];
readline.createInterface({
    input: fs.createReadStream(filename),
    terminal: false
}).on('line', function(line) {
   console.log('Line: ' + line);
});

I had precisely this problem, but I needed sequential plots to have highly contrasting color. I was also doing plots with a common sub-plot containing reference data, so I wanted the color sequence to be consistently repeatable.

I initially tried simply generating colors randomly, reseeding the RNG before each plot. This worked OK (commented-out in code below), but could generate nearly indistinguishable colors. I wanted highly contrasting colors, ideally sampled from a colormap containing all colors.

I could have as many as 31 data series in a single plot, so I chopped the colormap into that many steps. Then I walked the steps in an order that ensured I wouldn't return to the neighborhood of a given color very soon.

My data is in a highly irregular time series, so I wanted to see the points and the lines, with the point having the 'opposite' color of the line.

Given all the above, it was easiest to generate a dictionary with the relevant parameters for plotting the individual series, then expand it as part of the call.

Here's my code. Perhaps not pretty, but functional.

from matplotlib import cm
cmap = cm.get_cmap('gist_rainbow')  #('hsv') #('nipy_spectral')

max_colors = 31   # Constant, max mumber of series in any plot.  Ideally prime.
color_number = 0  # Variable, incremented for each series.

def restart_colors():
    global color_number
    color_number = 0
    #np.random.seed(1)

def next_color():
    global color_number
    color_number += 1
    #color = tuple(np.random.uniform(0.0, 0.5, 3))
    color = cmap( ((5 * color_number) % max_colors) / max_colors )
    return color

def plot_args():  # Invoked for each plot in a series as: '**(plot_args())'
    mkr = next_color()
    clr = (1 - mkr[0], 1 - mkr[1], 1 - mkr[2], mkr[3])  # Give line inverse of marker color
    return {
        "marker": "o",
        "color": clr,
        "mfc": mkr,
        "mec": mkr,
        "markersize": 0.5,
        "linewidth": 1,
    }

My context is JupyterLab and Pandas, so here's sample plot code:

restart_colors()  # Repeatable color sequence for every plot

fig, axs = plt.subplots(figsize=(15, 8))
plt.title("%s + T-meter"%name)

# Plot reference temperatures:
axs.set_ylabel("°C", rotation=0)
for s in ["T1", "T2", "T3", "T4"]:
    df_tmeter.plot(ax=axs, x="Timestamp", y=s, label="T-meter:%s" % s, **(plot_args()))

# Other series gets their own axis labels
ax2 = axs.twinx()
ax2.set_ylabel(units)

for c in df_uptime_sensors:
    df_uptime[df_uptime["UUID"] == c].plot(
        ax=ax2, x="Timestamp", y=units, label="%s - %s" % (units, c), **(plot_args())
    )

fig.tight_layout()
plt.show()

The resulting plot may not be the best example, but it becomes more relevant when interactively zoomed in.

I've created a new data selector that should enable you to do nested querying and AND conditions. Usage:

$('a:data(category==music,artist.name==Madonna)');

The pattern is:

:data( {namespace} [{operator} {check}]  )

"operator" and "check" are optional. So, if you only have :data(a.b.c) it will simply check for the truthiness of a.b.c.

You can see the available operators in the code below. Amongst them is ~= which allows regex testing:

$('a:data(category~=^mus..$,artist.name~=^M.+a$)');

I've tested it with a few variations and it seems to work quite well. I'll probably add this as a Github repo soon (with a full test suite), so keep a look out!

The code:

(function(){

    var matcher = /\s*(?:((?:(?:\\\.|[^.,])+\.?)+)\s*([!~><=]=|[><])\s*("|')?((?:\\\3|.)*?)\3|(.+?))\s*(?:,|$)/g;

    function resolve(element, data) {

        data = data.match(/(?:\\\.|[^.])+(?=\.|$)/g);

        var cur = jQuery.data(element)[data.shift()];

        while (cur && data[0]) {
            cur = cur[data.shift()];
        }

        return cur || undefined;

    }

    jQuery.expr[':'].data = function(el, i, match) {

        matcher.lastIndex = 0;

        var expr = match[3],
            m,
            check, val,
            allMatch = null,
            foundMatch = false;

        while (m = matcher.exec(expr)) {

            check = m[4];
            val = resolve(el, m[1] || m[5]);

            switch (m[2]) {
                case '==': foundMatch = val == check; break;
                case '!=': foundMatch = val != check; break;
                case '<=': foundMatch = val <= check; break;
                case '>=': foundMatch = val >= check; break;
                case '~=': foundMatch = RegExp(check).test(val); break;
                case '>': foundMatch = val > check; break;
                case '<': foundMatch = val < check; break;
                default: if (m[5]) foundMatch = !!val;
            }

            allMatch = allMatch === null ? foundMatch : allMatch && foundMatch;

        }

        return allMatch;

    };

}());

Be careful here.

FlushDB deletes all keys in the current database while FlushALL deletes all keys in all databases on the current host.

There already exists a function for this:

from operator import itemgetter

my_dict = {x: x**2 for x in range(10)}

itemgetter(1, 3, 2, 5)(my_dict)
#>>> (1, 9, 4, 25)

itemgetter will return a tuple if more than one argument is passed. To pass a list to itemgetter, use

itemgetter(*wanted_keys)(my_dict)

Keep in mind that itemgetter does not wrap its output in a tuple when only one key is requested, and does not support zero keys being requested.

You may add this values to your style android:windowMinWidthMajor and android:windowMinWidthMinor

<style name="Theme_Dialog" parent="android:Theme.Holo.Dialog">
    ...
    <item name="android:windowMinWidthMajor">97%</item>
    <item name="android:windowMinWidthMinor">97%</item>
</style>

>>> '{:08b}'.format(1)
'00000001'

See: Format Specification Mini-Language

Note for Python 2.6 or older, you cannot omit the positional argument identifier before :, so use

>>> '{0:08b}'.format(1)
'00000001'      

I suggest using QueryPath for parsing XML and HTML in PHP. It's basically much the same syntax as jQuery, only it's on the server side.

My short contribution, for sharing the same problem with Talend Open Studio 64 bit version.

1. Launch ..\TOS_DI-Win32-20150702_1326-V6.0.0\TOS_DI-win-x86_64.exe manually (not link an startup Windows menu)
2. and this registry error message appears

To resolve this, remove all java.exe, javaw.exe and javaws.exe files on c:\ProgramData\Oracle\Java\javapath\

and TOS start with 64 bits version correctly !

Check out the basics of regular expressions in a tutorial. All it requires is two anchors and a repeated character class:

^[a-zA-Z ._-]*$

If you use the case-insensitive modifier, you can shorten this to

^[a-z ._-]*$

Note that the space is significant (it is just a character like any other).

If you find the notation awkward, maybe the -R-option does help. It outpouts the date in RFC 2822 format. So you won't need all those identifiers: date -d @1278999698 -R. Another possibility is to output the date in seconds in your locale: date -d @1278999698 +%c. Should be easy to remember. :-)

You could use SqlMethods.Like(matchExpression,pattern)

var results = from c in db.costumers
              where SqlMethods.Like(c.FullName, "%"+FirstName+"%,"+LastName)
              select c;

The use of this method outside of LINQ to SQL will always throw a NotSupportedException exception.

//validate
$receivedRecaptcha = $_POST['recaptchaRes'];
$google_secret =  "Yoursecretgooglepapikey";
$verifiedRecaptchaUrl = 'https://www.google.com/recaptcha/api/siteverify?secret='.$google_secret.'&response='.$receivedRecaptcha;
$handle = curl_init($verifiedRecaptchaUrl);
curl_setopt($handle,  CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, false); // not safe but works
//curl_setopt($handle, CURLOPT_CAINFO, "./my_cert.pem"); // safe
$response = curl_exec($handle);
$httpCode = curl_getinfo($handle, CURLINFO_HTTP_CODE);
curl_close($handle);
if ($httpCode >= 200 && $httpCode < 300) {
  if (strlen($response) > 0) {
        $responseobj = json_decode($response);
        if(!$responseobj->success) {
            echo "reCAPTCHA is not valid. Please try again!";
            }
        else {
            echo "reCAPTCHA is valid.";
        }
    }
} else {
  echo "curl failed. http code is ".$httpCode;
}

I ran into this same issue and found the solution here: https://dzone.com/articles/persistence-layer-spring-data

I had renamed an entity property. But with Springs Automatic Custom Queries there was an interface defined for the old property name.

public interface IFooDAO extends JpaRepository< Foo, Long >{
     Foo findByOldPropName( final String name );
}

The error indicated that it could no longer find "OldPropName" and threw the exception.

To quote the article on DZone:

When Spring Data creates a new Repository implementation, it analyzes all the methods defined by the interfaces and tries to automatically generate queries from the method name. While this has limitations, it is a very powerful and elegant way of defining new custom access methods with very little effort. For example, if the managed entity has a name field (and the Java Bean standard getter and setter for that field), defining the findByName method in the DAO interface will automatically generate the correct query:

public interface IFooDAO extends JpaRepository< Foo, Long >{
     Foo findByName( final String name );
}

This is a relatively simple example; a much larger set of keywords is supported by query creation mechanism.

In the case that the parser cannot match the property with the domain object field, the following exception is thrown:

java.lang.IllegalArgumentException: No property nam found for type class org.rest.model.Foo

The problem is that your Python version and the library you want to use are not same versionally (Python). Even if you install Python's latest version, your PATH might not change properly and automatically. Thus, you should change it manually.After matching their version, it will work.

Ex: When I tried to install Django3, I got same error. I noticed that my PATH still seems C:\python27\Scripts though I already install Python3.8, so that I manually edited my PATH C:\python38\Scripts and reinstalled pip install Django and everything worked well.

There's always the good ol' trick:

console.log("\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n");

or a shorter variation of the above:

console.log('\n'.repeat('25'));

Not the most elegant solution, I know :) ... but works.

For me, I usually just print a long "-----" separator line to help make the logs easier to read.

It does not exactly answer your question, but to get around the problem,

1. you can either create a .cmd file with following content:

   start netbeans --jdkhome c:\path\to\jdk

2. or in the shortcut of Netbeans set the above option.

The correct solution to get the Prompt value in a non-templated control context is:

@Html.TextBoxFor(model => model.Email, 
    new { placeholder = ModelMetadata.FromLambdaExpression(m => m.Email, ViewData).Watermark }
)

This will also not double-escape the watermark text.

Use first the method OpenTextFile, and then...

either read the file at once with the method ReadAll:

Set file = fso.OpenTextFile("C:\test.txt", 1)
content = file.ReadAll

or line by line with the method ReadLine:

Set dict = CreateObject("Scripting.Dictionary")
Set file = fso.OpenTextFile ("c:\test.txt", 1)
row = 0
Do Until file.AtEndOfStream
  line = file.Readline
  dict.Add row, line
  row = row + 1
Loop

file.Close

'Loop over it
For Each line in dict.Items
  WScript.Echo line
Next

multipart/form-data

Note. Please consult RFC2388 for additional information about file uploads, including backwards compatibility issues, the relationship between "multipart/form-data" and other content types, performance issues, etc.

Please consult the appendix for information about security issues for forms.

The content type "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.

The content type "multipart/form-data" follows the rules of all multipart MIME data streams as outlined in RFC2045. The definition of "multipart/form-data" is available at the [IANA] registry.

A "multipart/form-data" message contains a series of parts, each representing a successful control. The parts are sent to the processing agent in the same order the corresponding controls appear in the document stream. Part boundaries should not occur in any of the data; how this is done lies outside the scope of this specification.

As with all multipart MIME types, each part has an optional "Content-Type" header that defaults to "text/plain". User agents should supply the "Content-Type" header, accompanied by a "charset" parameter.

application/x-www-form-urlencoded

This is the default content type. Forms submitted with this content type must be encoded as follows:

Control names and values are escaped. Space characters are replaced by +', and then reserved characters are escaped as described in [RFC1738], section 2.2: Non-alphanumeric characters are replaced by%HH', a percent sign and two hexadecimal digits representing the ASCII code of the character. Line breaks are represented as "CR LF" pairs (i.e., %0D%0A'). The control names/values are listed in the order they appear in the document. The name is separated from the value by=' and name/value pairs are separated from each other by `&'.

application/x-www-form-urlencoded the body of the HTTP message sent to the server is essentially one giant query string -- name/value pairs are separated by the ampersand (&), and names are separated from values by the equals symbol (=). An example of this would be:

MyVariableOne=ValueOne&MyVariableTwo=ValueTwo

The content type "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.

To make Rajneesh071's code complete, you may also want to set the navigation bar's title color (and font, if you want) since the default behavior changed from iOS 6 to 7:

NSArray *ver = [[UIDevice currentDevice].systemVersion componentsSeparatedByString:@"."];
if ([[ver objectAtIndex:0] intValue] >= 7)
{
    self.navigationController.navigationBar.barTintColor = [UIColor blackColor];
    self.navigationController.navigationBar.translucent = NO;
    NSMutableDictionary *textAttributes = [[NSMutableDictionary alloc] initWithDictionary:mainNavController.navigationBar.titleTextAttributes];
    [textAttributes setValue:[UIColor whiteColor] forKey:UITextAttributeTextColor];
    self.navigationController.navigationBar.titleTextAttributes = textAttributes;
}
else
{
    self.navigationController.navigationBar.tintColor = [UIColor blackColor];
}

Mockito allows mocking abstract classes by means of the @Mock annotation:

public abstract class My {

    public abstract boolean myAbstractMethod();

    public void myNonAbstractMethod() {
        // ...
    }
}

@RunWith(MockitoJUnitRunner.class)
public class MyTest {

    @Mock(answer = Answers.CALLS_REAL_METHODS)
    private My my;

    @Test
    private void shouldPass() {
        BDDMockito.given(my.myAbstractMethod()).willReturn(true);
        my.myNonAbstractMethod();
        // ...
    }
}

The disadvantage is that it cannot be used if you need constructor parameters.

use pgAdmin or use pg_proc to get the source of your stored procedures. pgAdmin does the same.

Using new "Counter" class in collections module, based on lazyr's answer:

...     dups=[i for i in counter if counter[i]!=1] #['1','3','2']
...     result={}
...     for item in dups:
...             result[item]=[i for i,j in enumerate(n) if j==item] 
...     return result

This is what worked for me, since I wanted to have a separate index column

df = pd.DataFrame.from_dict(some_dict, orient="index").reset_index()
df.columns = ['A', 'B']

After opening local bootstrap.min.css in visual studio code, it looked unindented. Tried the commad ALT+Shift+F but in vain.

Then installed

CSS Formatter extension.

Reloaded it and ALT+Shift+F indented my CSS file with charm.

Bingo !!!

If any one's trying to fetch all headers that were passed then just simply use:

dict(request.headers)

it gives you all the headers in a dict from which you can actually do whatever ops you want to. In my use case I had to forward all headers to another API since the python API was a proxy

Consider each row as a column, and each column as a row .. use j,i instead of i,j

demo: http://ideone.com/lvsxKZ

#include <iostream> 
using namespace std;

int main ()
{
    char A [3][3] =
    {
        { 'a', 'b', 'c' },
        { 'd', 'e', 'f' },
        { 'g', 'h', 'i' }
    };

    cout << "A = " << endl << endl;

    // print matrix A
    for (int i=0; i<3; i++)
    {
        for (int j=0; j<3; j++) cout << A[i][j];
        cout << endl;
    }

    cout << endl << "A transpose = " << endl << endl;

    // print A transpose
    for (int i=0; i<3; i++)
    {
        for (int j=0; j<3; j++) cout << A[j][i];
        cout << endl;
    }

    return 0;
}

Consider breaking this problem up into two pieces:

1. filter out the items that match the given regular expression
2. determine if that filtered list has 0 matches in it

const sampleStringData = ["frog", "pig", "tiger"];

const matches = sampleStringData.filter((animal) => /any.regex.here/.test(animal));

if (matches.length === 0) {
  console.log("No matches");
}

Open the Terminal -> copy below command

sudo gem install cocoapods

It will install the latest stable version of cocoapods.

after that, you need to update pod using below command

pod setup

You can check pod version using below command

pod --version

(Xcode 5 iOS 7 SDK example) Here is a Universal App example using the scrollview setBounces function. It is an open source project / example located here: Link to SimpleWebView (Project Zip and Source Code Example)

String rat_values = "Food 1 | Service 3 | Atmosphere 3 | Value for money 1 ";
    String[] value_split = rat_values.split("\\|");
    for (String string : value_split) {

        System.out.println(string);

    }

If you are using underscoreJs then you can simply use _.isEqual function and it compares all keys and values at each and every level of hierarchy like below example.

var object = {"status":"inserted","id":"5799acb792b0525e05ba074c","data":{"workout":[{"set":[{"setNo":1,"exercises":[{"name":"hjkh","type":"Reps","category":"Cardio","set":{"reps":5}}],"isLastSet":false,"index":0,"isStart":true,"startDuration":1469689001989,"isEnd":true,"endDuration":1469689003323,"speed":"00:00:01"}],"setType":"Set","isSuper":false,"index":0}],"time":"2016-07-28T06:56:52.800Z"}};

var object1 = {"status":"inserted","id":"5799acb792b0525e05ba074c","data":{"workout":[{"set":[{"setNo":1,"exercises":[{"name":"hjkh","type":"Reps","category":"Cardio","set":{"reps":5}}],"isLastSet":false,"index":0,"isStart":true,"startDuration":1469689001989,"isEnd":true,"endDuration":1469689003323,"speed":"00:00:01"}],"setType":"Set","isSuper":false,"index":0}],"time":"2016-07-28T06:56:52.800Z"}};

console.log(_.isEqual(object, object1));//return true

If all the keys and values for those keys are same in both the objects then it will return true, otherwise return false.

If you want to send more than two person or DL :

echo "Message Body" | mailx -s "Message Title" -r [email protected] [email protected],[email protected]

here:

• -s = subject or mail title
• -r = sender mail or DL

The output looks correct to me:

Invalid JavaScript code: sun.org.mozilla.javascript.internal.EvaluatorException: missing } after property list (<Unknown source>) in <Unknown source>; at line number 1

I think Invalid Javascript code: .. is the start of the exception message.

Normally the stacktrace isn't returned with the message:

try {
    throw new RuntimeException("hu?\ntrace-line1\ntrace-line2");
} catch (Exception e) {
    System.out.println(e.getMessage()); // prints "hu?"
}

So maybe the code you are calling catches an exception and rethrows a ScriptException. In this case maybe e.getCause().getMessage() can help you.

This should work.

int i = 1;
foreach (ListViewItem lvi in listView.Items) {
    ...
    if(++i == 50) break;
}

Use non-static position along with greater z-index in child element:

.parent {
    position: absolute
    z-index: 100;
}

.child {
    position: relative;
    z-index: 101;
}

When you $ pip install jupyter several dependencies are installed. The best way to uninstall it completely is by running:

1. $ pip install pip-autoremove
2. $ pip-autoremove jupyter -y

Kindly refer to this related question.

pip-autoremove removes a package and its unused dependencies. Here are the docs.

Here is an easy way.

#animal represents any buttons from the DOM.
#animal-value is the input id that being targeted.

$("#animal").on('click', function(){
    var userVal = $("#animal-value").val(); // storing that value
    console.log(userVal); // logging the stored value to the console
    $("#animal-value").val('') // reseting it to empty
});

This worked for me:

collection.find({}, {"sort" : [['datefield', 'asc']]}, function (err, docs) { ... });

Using Node.js, Express.js, and Monk

^{In addition to Preet Sangha's explanation:}
Intellisense displays the extension methods with a blue arrow (e.g. in front of "Aggregate<>"):

You need a

I ran into this issue as well, but in order to use a safe pipe in my angular module, I installed the safe-pipe npm package, which you can find here. FYI, this worked in Angular 9.1.3, I haven't tried this in any other versions of Angular. Here's how you add it step by step:

1. Install the package via npm install safe-pipe or yarn add safe-pipe. This will store a reference to it in your dependencies in the package.json file, which you should already have from starting a new Angular project.

2. Add SafePipeModule module to NgModule.imports in your Angular module file like so:

   import { SafePipeModule } from 'safe-pipe';
   
   @NgModule({
       imports: [ SafePipeModule ]
   })
   export class AppModule { }
   
   

3. Add the safe pipe to an element in the template for the Angular component you are importing into your NgModule this way:

<element [property]="value | safe: sanitizationType"></element>

4. Here are some specific examples of the safePipe in an html element:

<div [style.background-image]="'url(' + pictureUrl + ')' | safe: 'style'" class="pic bg-pic"></div>
<img [src]="pictureUrl | safe: 'url'" class="pic" alt="Logo">
<iframe [src]="catVideoEmbed | safe: 'resourceUrl'" width="640" height="390"></iframe>
<pre [innerHTML]="htmlContent | safe: 'html'"></pre>

I would use this:

SELECT  Closing_Date = DATEADD(MONTH, DATEDIFF(MONTH, 0, Closing_Date), 0), 
        Category,  
        COUNT(Status) TotalCount 
FROM    MyTable
WHERE   Closing_Date >= '2012-02-01' 
AND     Closing_Date <= '2012-12-31'
AND     Defect_Status1 IS NOT NULL
GROUP BY DATEADD(MONTH, DATEDIFF(MONTH, 0, Closing_Date), 0), Category;

This will group by the first of every month, so

`DATEADD(MONTH, DATEDIFF(MONTH, 0, '20130128'), 0)` 

will give '20130101'. I generally prefer this method as it keeps dates as dates.

Alternatively you could use something like this:

SELECT  Closing_Year = DATEPART(YEAR, Closing_Date),
        Closing_Month = DATEPART(MONTH, Closing_Date),
        Category,  
        COUNT(Status) TotalCount 
FROM    MyTable
WHERE   Closing_Date >= '2012-02-01' 
AND     Closing_Date <= '2012-12-31'
AND     Defect_Status1 IS NOT NULL
GROUP BY DATEPART(YEAR, Closing_Date), DATEPART(MONTH, Closing_Date), Category;

It really depends what your desired output is. (Closing Year is not necessary in your example, but if the date range crosses a year boundary it may be).

I usually fix this errore following this msdn blog post Using LocalDB with Full IIS

This requires editing applicationHost.config file which is usually located in C:\Windows\System32\inetsrv\config. Following the instructions from KB 2547655 we should enable both flags for Application Pool ASP.NET v4.0, like this:

<add name="ASP.NET v4.0" autoStart="true" managedRuntimeVersion="v4.0"     managedPipelineMode="Integrated">
    <processModel identityType="ApplicationPoolIdentity" loadUserProfile="true" setProfileEnvironment="true" />
</add>

Use awk(another great bash utility) instead of grep where you dont have the line buffered option! It will continuously stream your data from tail.

this is how you use grep

tail -f <file> | grep pattern

This is how you would use awk

tail -f <file> | awk '/pattern/{print $0}'

The Excel number for a modern date is most easily calculated as the number of days since 12/30/1899 on the Gregorian calendar.

Excel treats the mythical date 01/00/1900 (i.e., 12/31/1899) as corresponding to 0, and incorrectly treats year 1900 as a leap year. So for dates before 03/01/1900, the Excel number is effectively the number of days after 12/31/1899.

However, Excel will not format any number below 0 (-1 gives you ##########) and so this only matters for "01/00/1900" to 02/28/1900, making it easier to just use the 12/30/1899 date as a base.

A complete function in DB2 SQL that accounts for the leap year 1900 error:

SELECT
   DAYS(INPUT_DATE)                 
   - DAYS(DATE('1899-12-30'))
   - CASE                       
        WHEN INPUT_DATE < DATE('1900-03-01')  
           THEN 1               
           ELSE 0               
     END

You do not specify why you think it is wrong but I can se two dangers:

BETWEEN can be implemented differently in different databases sometimes it is including the border values and sometimes excluding, resulting in that 1 and 31 of january would end up NOTHING. You should test how you database does this.

Also, if RATE_DATE contains hours also 2010-01-31 might be translated to 2010-01-31 00:00 which also would exclude any row with an hour other that 00:00.

I think that using the task scheduler to autostart programs is not very user friendly, and sometimes it has had side effects for me (e.g. tray icon for a program is not added).

To remedy this, I have made a program called Elevated Startup that first relaunches itself with administrator privileges, then it launches all files in a directory. Since Elevated Startup is now elevated, all the programs it then launches is also given administrator privileges. The directory is on the start menu next to the classic Startup directory, and works very much the same.

You may encounter one UAC dialog when the program relaunches itself, depending on your UAC settings.

You can get the program here: https://stefansundin.github.io/elevatedstartup/

I was looking for a similar solution, base on what was suggested on this thread, I use the following DateTime.Now.ToString("MM/dd/yyyy hh:mm:ss.fff") , and it work like charm. Note: that .fff are the precision numbers that you wish to capture.

Yes, you can use the isdigit() function to check for a digits :)

Here you go:

#include <iostream>
#include <cctype>
#include <string.h>

using namespace std;

int main(){

  char *str = "(555) 555-5555";
  int len = strlen(str);

  for (int i=0; i<len; i++){
      if (isdigit(*(str+i))){
        cout << *(str+i);
      }
  }

  cout << endl;


return 0;   
}

Hope it helps :)

I would do it in the simplest way, so anyone can understand what happens, even if there are smarter ways:

my $text = "";
while (my $line = <FILE>) {
    $text .= $line;
}

If you've installed .NET framework 4.6, you may see this error due to a VS bug. Workarounds and resolutions here:

EDIT:

As noted in some of the comments, this can happen behind the scenes after upgrading to Windows 10 or Visual Studio 2015.

You can do it like this:

 alter table [table_name] modify column [column_name] [column_type] AUTO_INCREMENT;

For example folder named new under E: drive

type the command:

e:\cd new

e:\new\attrib *.* -s -h /s /d

and all the files and folders are un-hidden

var sb = new StringBuilder();
sb.Append(first);
sb.AppendLine(); // which is equal to Append(Environment.NewLine);
sb.Append(second);
return sb.ToString();

This actually works for me:

Per the README.SSO that comes with the jtdsd distribution:

In order for Single Sign On to work, jTDS must be able to load the native SPPI library ntlmauth.dll. Place this DLL anywhere in the system path (defined by the PATH system variable) and you're all set.

I placed it in my jre/bin folder

I configured a port dedicated the sql server instance (2302) to alleviate the need for an instance name - just something I do. lportal is my database name.

In the old days, "/opt" was used by UNIX vendors like AT&T, Sun, DEC and 3rd-party vendors to hold "Option" packages; i.e. packages that you might have paid extra money for. I don't recall seeing "/opt" on Berkeley BSD UNIX. They used "/usr/local" for stuff that you installed yourself.

But of course, the true "meaning" of the different directories has always been somewhat vague. That is arguably a good thing, because if these directories had precise (and rigidly enforced) meanings you'd end up with a proliferation of different directory names.

According to the Filesystem Hierarchy Standard, /opt is for "the installation of add-on application software packages". /usr/local is "for use by the system administrator when installing software locally".

If you need to extract an element key based on index, this function can be used:

public string getCard(int random)
{
    return Karta._dict.ElementAt(random).Key;
}

If you need to extract the Key where the element value is equal to the integer generated randomly, you can used the following function:

public string getCard(int random)
{
    return Karta._dict.FirstOrDefault(x => x.Value == random).Key;
}

Side Note: The first element of the dictionary is The Key and the second is the Value

1. Use awk to put the user ID in front.
2. Sort

3. Use sed to remove the duplicate user ID, assuming user IDs do not contain any spaces.

   awk -F, '{ print $3, $0 }' user.csv | sort | sed 's/^.* //'

1. Download MySQL Connector .NET (6.9.4 on this date) from here and install it CUSTOM!
2. Remove the ASP.NET WEB providers option or the installer will write in machine.config!
3. Download MySQL for Visual Studio from here and install it CUSTOM. Be sure to check the integration options. You need this step because after Connector .NET 6.7 the installer will no longer integrate the connector with Visual Studio. This installer can take longer then expected. This is it.

You can install it from alternate download here which should have integrated with VS correctly but it did not and I got a strange error and after the reinstall it is ok.

I had the same problem but when I looked closely I found that, it was causing because I was trying to put the foreign key values into the tables before that key was assigned its primary key value. e.g. I had two tables "customers" and "films", "cust_id" and "film_id" were primary key respectively. "customer" had one-to-many relation with "films" so I had "cust_id" as foreign key in "films" tables. But I was trying to put values to "films" table first, so I got that problem.

If you're using SQL Server 2005 or later, use varchar(MAX). The text datatype is deprecated and should not be used for new development work. From the docs:

Important

ntext , text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

try:

public ActionResult Index() {
    return RedirectToAction("actionName");
    // or
    return RedirectToAction("actionName", "controllerName");
    // or
    return RedirectToAction("actionName", "controllerName", new {/* routeValues, for example: */ id = 5 });
}

and in .cshtml view:

@Html.ActionLink("linkText","actionName")

OR:

@Html.ActionLink("linkText","actionName","controllerName")

OR:

@Html.ActionLink("linkText", "actionName", "controllerName", 
    new { /* routeValues forexample: id = 6 or leave blank or use null */ }, 
    new { /* htmlAttributes forexample: @class = "my-class" or leave blank or use null */ })

Notice using null in final expression is not recommended, and is better to use a blank new {} instead of null

As per my understanding you want data in dictionary as shown below:

key1: value1-1,value1-2,value1-3....value100-1
key2: value2-1,value2-2,value2-3....value100-2
key3: value3-1,value3-2,value3-2....value100-3

for this you can use list for each dictionary keys:

case_list = {}
for entry in entries_list:
    if key in case_list:
        case_list[key1].append(value)
    else:
        case_list[key1] = [value]

First off, you have to specify you wish to use Document Literal style:

$client = new SoapClient(NULL, array(
    'location' => 'https://example.com/path/to/service',
    'uri' => 'http://example.com/wsdl',
    'trace' => 1,
    'use' => SOAP_LITERAL)
);

Then, you need to transform your data into a SoapVar; I've written a simple transform function:

function soapify(array $data)
{
        foreach ($data as &$value) {
                if (is_array($value)) {
                        $value = soapify($value);
                }
        }

        return new SoapVar($data, SOAP_ENC_OBJECT);
}

Then, you apply this transform function onto your data:

$data = soapify(array(
    'Acquirer' => array(
        'Id' => 'MyId',
        'UserId' => 'MyUserId',
        'Password' => 'MyPassword',
    ),
));

Finally, you call the service passing the Data parameter:

$method = 'Echo';

$result = $client->$method(new SoapParam($data, 'Data'));

I did tests with buffer size, running this code

using (var stream = new BufferedStream(File.OpenRead(file), bufferSize))
{
    SHA256Managed sha = new SHA256Managed();
    byte[] checksum = sha.ComputeHash(stream);
    return BitConverter.ToString(checksum).Replace("-", String.Empty).ToLower();
}

And I tested with a file of 29½ GB in size, the results were

• 10.000: 369,24s
• 100.000: 362,55s
• 1.000.000: 361,53s
• 10.000.000: 434,15s
• 100.000.000: 435,15s
• 1.000.000.000: 434,31s
• And 376,22s when using the original, none buffered code.

I am running an i5 2500K CPU, 12 GB ram and a OCZ Vertex 4 256 GB SSD drive.

So I thought, what about a standard 2TB harddrive. And the results were like this

• 10.000: 368,52s
• 100.000: 364,15s
• 1.000.000: 363,06s
• 10.000.000: 678,96s
• 100.000.000: 617,89s
• 1.000.000.000: 626,86s
• And for none buffered 368,24

So I would recommend either no buffer or a buffer of max 1 mill.

The way to use the ellipsis or varargs inside the method is as if it were an array:

public void PrintWithEllipsis(String...setOfStrings) {
    for (String s : setOfStrings)
        System.out.println(s);
}

This method can be called as following:

obj.PrintWithEllipsis(); // prints nothing
obj.PrintWithEllipsis("first"); // prints "first"
obj.PrintWithEllipsis("first", "second"); // prints "first\nsecond"

Inside PrintWithEllipsis, the type of setOfStrings is an array of String. So you could save the compiler some work and pass an array:

String[] argsVar = {"first", "second"};
obj.PrintWithEllipsis(argsVar);

For varargs methods, a sequence parameter is treated as being an array of the same type. So if two signatures differ only in that one declares a sequence and the other an array, as in this example:

void process(String[] s){}
void process(String...s){}

then a compile-time error occurs.

Source: The Java Programming Language specification, where the technical term is variable arity parameter rather than the common term varargs.

And on Windows 10 computers:

On the first run, you use xsd.exe and you convert your sample XML into a XSD file (XML schema file):

xsd yourfile.xml

This gives you yourfile.xsd, which in a second step, you can convert again using xsd.exe into a C# class:

xsd yourfile.xsd /c

This should give you a file yourfile.cs which will contain a C# class that you can use to deserialize the XML file you're getting - something like:

XmlSerializer serializer = new XmlSerializer(typeof(msg));
msg resultingMessage = (msg)serializer.Deserialize(new XmlTextReader("yourfile.xml"));

Should work pretty well for most cases.

Update: the XML serializer will take any stream as its input - either a file or a memory stream will be fine:

XmlSerializer serializer = new XmlSerializer(typeof(msg));
MemoryStream memStream = new MemoryStream(Encoding.UTF8.GetBytes(inputString));
msg resultingMessage = (msg)serializer.Deserialize(memStream);

or use a StringReader:

XmlSerializer serializer = new XmlSerializer(typeof(msg));
StringReader rdr = new StringReader(inputString);
msg resultingMessage = (msg)serializer.Deserialize(rdr);

I use that for all status (update, insert and delete)

                                                 ) AS A ORDER BY A.Date DESC

You can just give it try to your code:

Array ints = Array.CreateInstance(typeof(int), 5);
ints.SetValue(10, 0);

ints.SetValue(20, 1);
ints.SetValue(10, 2);
ints.SetValue(34, 3);
ints.SetValue(113, 4);

int[] anyVariable=(int[])ints;

Then you can just use the anyVariable as your code.

If you want to remove/clean all the values from local storage than use

localStorage.clear();

And if you want to remove the specific item from local storage than use the following code

localStorage.removeItem(key);

Use push_back():

std::string y("Hello worl");
y.push_back('d')
std::cout << y;

Quick answer

On src, you can always specify files to ignore using "!".

Example (you want to exclude all *.min.js files on your js folder and subfolder:

gulp.src(['js/**/*.js', '!js/**/*.min.js'])

You can do it as well for individual files.

Expanded answer:

Extracted from gulp documentation:

gulp.src(globs[, options])

Emits files matching provided glob or an array of globs. Returns a stream of Vinyl files that can be piped to plugins.

glob refers to node-glob syntax or it can be a direct file path.

So, looking to node-glob documentation we can see that it uses the minimatch library to do its matching.

On minimatch documentation, they point out the following:

if the pattern starts with a ! character, then it is negated.

And that is why using ! symbol will exclude files / directories from a gulp task

you can use

select cast((630/60.0) as  decimal(16,2))

ex mode is easiest:

:%s/$/,

: - enter command mode
% - for every line
s/ - substitute
$ - the end of the line
/ - and change it to
, - a comma

You can use df.index to access the index object and then get the values in a list using df.index.tolist(). Similarly, you can use df['col'].tolist() for Series.

[object Object] is the default toString representation of an object in javascript.

If you want to know the properties of your object, just foreach over it like this:

for(var property in obj) {
    alert(property + "=" + obj[property]);
}

In your particular case, you are getting a jQuery object. Try doing this instead:

$('#senddvd').click(function ()
{
   alert('hello');
   var a=whichIsVisible();
   alert(whichIsVisible().attr("id"));
});

This should alert the id of the visible element.

SqlBulkCopy class is best for SQL server,

Doing Bulk Upload/Insert of DataTable to a Table in SQL server in C#

WhatsApp has chosen Erlang a language built for writing scalable applications that are designed to withstand errors. Erlang uses an abstraction called the Actor model for it's concurrency - http://en.wikipedia.org/wiki/Actor_(programming_language) Instead of the more traditional shared memory approach, actors communicate by sending each other messages. Actors unlike threads are designed to be lightweight. Actors could be on the same machine or on different machines and the message passing abstractions works for both. A simple implementation of WhatsApp could be: Each user/device is represented as an actor. This actor is responsible for handling the inbox of the user, how it gets serialized to disk, the messages that the user sends and the messages that the user receives. Let's assume that Alice and Bob are friends on WhatsApp. So there is an an Alice actor and a Bob actor.

Let's trace a series of messages flowing back and forth:

Alice decides to message Bob. Alice's phone establishes a connection to the WhatsApp server and it is established that this connection is definitely from Alice's phone. Alice now sends via TCP the following message: "For Bob: A giant monster is attacking the Golden Gate Bridge". One of the WhatsApp front end server deserializes this message and delivers this message to the actor called Alice.

Alice the actor decides to serialize this and store it in a file called "Alice's Sent Messages", stored on a replicated file system to prevent data loss due to unpredictable monster rampage. Alice the actor then decides to forward this message to Bob the actor by passing it a message "Msg1 from Alice: A giant monster is attacking the Golden Gate Bridge". Alice the actor can retry with exponential back-off till Bob the actor acknowledges receiving the message.

Bob the actor eventually receives the message from (2) and decides to store this message in a file called "Bob's Inbox". Once it has stored this message durably Bob the actor will acknowledge receiving the message by sending Alice the actor a message of it's own saying "I received Msg1". Alice the actor can now stop it's retry efforts. Bob the actor then checks to see if Bob's phone has an active connection to the server. It does and so Bob the actor streams this message to the device via TCP.

Bob sees this message and replies with "For Alice: Let's create giant robots to fight them". This is now received by Bob the actor as outlined in Step 1. Bob the actor then repeats Step 2 and 3 to make sure Alice eventually receives the idea that will save mankind.

WhatsApp actually uses the XMPP protocol instead of the vastly superior protocol that I outlined above, but you get the point.

This working good

$('#id-of-table').on('draw.dt', function() {
    // do action here
});

A simple, although awk-less solution in bash:

while IFS=, read -r a a a b; do echo "$a"; done <inputfile

It works faster for small files (<100 lines) then awk as it uses less resources (avoids calling the expensive fork and execve system calls).

EDIT from Ed Morton (sorry for hi-jacking the answer, I don't know if there's a better way to address this):

To put to rest the myth that shell will run faster than awk for small files:

$ wc -l file
99 file

$ time while IFS=, read -r a a a b; do echo "$a"; done <file >/dev/null

real    0m0.016s
user    0m0.000s
sys     0m0.015s

$ time awk -F, '{print $3}' file >/dev/null

real    0m0.016s
user    0m0.000s
sys     0m0.015s

I expect if you get a REALY small enough file then you will see the shell script run in a fraction of a blink of an eye faster than the awk script but who cares?

And if you don't believe that it's harder to write robust shell scripts than awk scripts, look at this bug in the shell script you posted:

$ cat file
a,b,-e,d
$ cut -d, -f3 file
-e
$ awk -F, '{print $3}' file
-e
$ while IFS=, read -r a a a b; do echo "$a"; done <file

You can write a pretty simple embedded Jetty Java server.

Embedded Jetty means that the server (Jetty) shipped together with the application as opposed of deploying the application on external Jetty server.

So if in non-embedded approach your webapp built into WAR file which deployed to some external server (Tomcat / Jetty / etc), in embedded Jetty, you write the webapp and instantiate the jetty server in the same code base.

An example for embedded Jetty Java server you can git clone and use: https://github.com/stas-slu/embedded-jetty-java-server-example

The following statement is not entirely accurate:

"So if you are calling other functionality, including static classes, from your page, you should be fine"

I am calling a static method that references the session through HttpContext.Current.Session and it is null. However, I am calling the method via a webservice method through ajax using jQuery.

As I found out here you can fix the problem with a simple attribute on the method, or use the web service session object:

There’s a trick though, in order to access the session state within a web method, you must enable the session state management like so:

[WebMethod(EnableSession = true)]

By specifying the EnableSession value, you will now have a managed session to play with. If you don’t specify this value, you will get a null Session object, and more than likely run into null reference exceptions whilst trying to access the session object.

Thanks to Matthew Cosier for the solution.

Just thought I'd add my two cents.

XSD is schema for WSDL file. XSD contain datatypes for WSDL. Element declared in XSD is valid to use in WSDL file. We can Check WSDL against XSD to check out web service WSDL is valid or not.

• Because they already know C
• Because they're building an embedded app for a platform that only has a C compiler
• Because they're maintaining legacy software written in C
• You're writing something on the level of an operating system, a relational database engine, or a retail 3D video game engine.

You can get data from post response Headers in this way (Angular 6):

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

const httpOptions = {
  headers: new HttpHeaders({ 'Content-Type': 'application/json' }),
  observe: 'response' as 'response'
};

this.http.post(link,body,httpOptions).subscribe((res: HttpResponse<any>) => {
  console.log(res.headers.get('token-key-name'));
})

Arrays are different than ArrayLists, on which you could call add. You'll need an index first. Declare i before the for loop. Then you can use an array access expression to assign the element to the array.

num[i] = s;
i++;

I got the same error. it was because I was accessing the https port using http.. The issue solved when I changed http to https.

I would recommend you having a look at the basics of conditioning in bash.

The symbol "[" is a command and must have a whitespace prior to it. If you don't give whitespace after your elif, the system interprets elif[ as a a particular command which is definitely not what you'd want at this time.

Usage:

elif(A COMPULSORY WHITESPACE WITHOUT PARENTHESIS)[(A WHITE SPACE WITHOUT PARENTHESIS)conditions(A WHITESPACE WITHOUT PARENTHESIS)]

In short, edit your code segment to:

elif [ "$seconds" -gt 0 ]

You'd be fine with no compilation errors. Your final code segment should look like this:

#!/bin/sh    
if [ "$seconds" -eq 0 ];then
       $timezone_string="Z"
    elif [ "$seconds" -gt 0 ]
    then
       $timezone_string=`printf "%02d:%02d" $seconds/3600 ($seconds/60)%60`
    else
       echo "Unknown parameter"
    fi

This is similar to Kannan's answer. However, this fixes an issue where the token should not be sent to cross-domain sites. This will only set the header if it is a local request.

HTML:

<meta name="csrf-token" content="{{ csrf_token() }}">

JS:

$.ajaxSetup({
    beforeSend: function(xhr, type) {
        if (!type.crossDomain) {
            xhr.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'));
        }
    },
});

The reason might be because the IPython module is not in your PYTHONPATH.

If you donwload IPython and then do python setup.py install

The setup doesn't add the module IPython to your python path. You might want to add it to your PYTHONPATH manually. It should work after you do :

export PYTHONPATH=/pathtoIPython:$PYTHONPATH

Add this line in your .bashrc or .profile to make it permanent.

Use the this.ngOnInit(); to reload the same component instead reloading the entire page!!

DeleteEmployee(id:number)
  {
    this.employeeService.deleteEmployee(id)
    .subscribe( 
      (data) =>{
        console.log(data);

        this.ngOnInit();

      }),
      err => {
        console.log("Error");
      }   
  }

My favorite way to do this is with an extension function called 'Map':

public static void Map<T>(this IEnumerable<T> source, Action<T> func)
{
    foreach (T i in source)
        func(i);
}

Then you can add all the rows like so:

X.Map(item => this.dataGridView1.Rows.Add(item.ID, item.Name));

$array = array('foo' => 'bar', 33 => 'bin', 'lorem' => 'ipsum');
$array = array_values($array);
echo $array[0]; //bar
echo $array[1]; //bin
echo $array[2]; //ipsum

Classic 8-bit LaTeX is very restricted in which UTF8 characters it can use; it's highly dependent on the encoding of the font you're using and which glyphs that font has available.

Since you don't give a specific example, it's hard to know exactly where the problem is — whether you're attempting to use a glyph that your font doesn't have or whether you're not using the correct font encoding in the first place.

Here's a minimal example showing how a few UTF8 characters can be used in a LaTeX document:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[utf8]{inputenc}
\begin{document}
‘Héllø—thêrè.’
\end{document}

You may have more luck with the [utf8x] encoding, but be slightly warned that it's no longer supported and has some idiosyncrasies compared with [utf8] (as far as I recall; it's been a while since I've looked at it). But if it does the trick, that's all that matters for you.

• for better performace use the biggest blocksize you RAM can accomodate (will send less I/O calls to the OS)
• for better accurancy and data recovery set the blocksize to the native sector size of the input

As dd copies data with the conv=noerror,sync option, any errors it encounters will result in the remainder of the block being replaced with zero-bytes. Larger block sizes will copy more quickly, but each time an error is encountered the remainder of the block is ignored.

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

If you're using the standard SVN installation the svn:// connection will work on tcpip port 3690 and so it's basically impossible to connect unless you change your network configuration (you said only Http traffic is allowed) or you install the http module and Apache on the server hosting your SVN server.

Complete answer is located in the official PostgreSQL documentation.

You can use new PG9.0 anonymous code block feature (http://www.postgresql.org/docs/9.1/static/sql-do.html )

DO $$
DECLARE v_List TEXT;
BEGIN
  v_List := 'foobar' ;
  SELECT *
  FROM   dbo.PubLists
  WHERE  Name = v_List;
  -- ...
END $$;

Also you can get the last insert id:

DO $$
DECLARE lastid bigint;
BEGIN
  INSERT INTO test (name) VALUES ('Test Name') 
  RETURNING id INTO lastid;

  SELECT * FROM test WHERE id = lastid;
END $$;

I know this is an old question, but I've just had the same frustrating issue for a couple of hours and wanted to share my solution. In my case the option "Managements Tools" wasn't available in the installation menu either. It wasn't just greyed out as disabled or already installed, but instead just missing, it wasn't anywhere on the menu.

So what finally worked for me was to use the Web Platform Installer 4.0, and check this for installation: Products > Database > "Sql Server 2008 R2 Management Objects". Once this is done, you can relaunch the installation and "Management Tools" will appear like previous answers stated.

Note there could also be a "Sql Server 2012 Shared Management Objects", but I think this is for different purposes.

Hope this saves someone the couple of hours I wasted into this.

My issue was caused because I have an & character in my Windows user name, so when installed in the default path I was getting the following error after running bin/studio.bat

This happened to me when an web request endpoint was switched to another server that accepted TLS1.2 requests only. Tried so many attempts mostly found on Stackoverflow like

1. Registry Keys ,
2. Added :
   System.Net.ServicePointManager.SecurityProtocol |= System.Net.SecurityProtocolType.Tls12; to Global.ASX OnStart,
3. Added in Web.config.
4. Updated .Net framework to 4.7.2 Still getting same Exception.

The exception received did no make justice to the actual problem I was facing and found no help from the service operator.

To solve this I have to add a new Cipher Suite TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 I have used IIS Crypto 2.0 Tool from here as shown below.

In Ubuntu, from MySQL monitor, you have already used this syntax:

mysql> use <dbname> -> The USE statement tells MySQL to use dbname as the default database for subsequent statements

mysql> source <file-path>

mysql> source /tmp/phonebook.sql;

Important: make sure the sql file is in a directory that mysql can access to like /tmp

PRIMARY KEY (id, name) didn't work for me. Adding a constraint did the job instead.

CREATE TABLE IF NOT EXISTS customer (
    id INTEGER, name TEXT,
    user INTEGER,
    CONSTRAINT PK_CUSTOMER PRIMARY KEY (user, id)
)

I found myself in a similar situation as the poster:

If I call "git add .", and then "git status" and it keeps saying "working directory clean" and has nothing to commit.

But I had a different solution than what's here. Since I came to this first, I hope to save others some time.

From the above answers and what I've seen elsewhere, the usual fixes to this problem are:

• Ensure there are actually saved changes on the file in question
• Ensure the file doesn't meet your exclude rules in .gitignore and .git/info/exclude
• Ensure you're not trying to add an empty folder. Git won't track those. Standard solution is to place a blank file named .gitkeep as a placeholder so git will track the folder.

In my case, I had originally tried to create a git repo around an existing repo (not knowing it was there). I had removed the .git folder from this sub repo a while ago, but I didn't realize that it was too late, and git was already tracking it as a submodule. You can read more about how these behave and how to remove them here, but

• the solution for me was to simply run git rm --cached path_to_submodule.

If you have SSH access, you don't need to SSH first and then copy, just use Secure Copy (SCP) from the destination.

scp user@host:/path/file /localpath/file

Wild card characters are supported, so

scp user@host:/path/folder/* /localpath/folder

will copy all of the remote files in that folder.If copying more then one directory.

note -r will copy all sub-folders and content too.

ok just my two cents, use a is string method:

public static boolean isString(Object thing) {
    return thing instanceof String;
}

public void someMethod(Object thing){
    if (!isString(thing)) {
        return null;
    }
    log.debug("my thing is valid");
}

setMargins() sets the INNER margins of the TextView, not the layout-margins. Is that what you want to do? This two different margins can be quite complicated.

If you want to set the layout margins, change the LayoutParams of the TextView (textview.getLayoutParams(), then change the parameters on the returned LayoutParams object).

You don't need to change anything on your LinearLayout.

Little addition to Jason's answer:

1. The ToShortDateString() is culture-sensitive.

From MSDN:

The string returned by the ToShortDateString method is culture-sensitive. It reflects the pattern defined by the current culture's DateTimeFormatInfo object. For example, for the en-US culture, the standard short date pattern is "M/d/yyyy"; for the de-DE culture, it is "dd.MM.yyyy"; for the ja-JP culture, it is "yyyy/M/d". The specific format string on a particular computer can also be customized so that it differs from the standard short date format string.

That's mean it's better to use the ToString() method and define format explicitly (as Jason said). Although if this string appeas in UI the ToShortDateString() is a good solution because it returns string which is familiar to a user.

2. If you need just today's date you can use DateTime.Today.

I know this is a pretty old question but this was my solution that helped with visualizing the table so you can create a class structure. This is also using the HTML Agility Pack

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(@"<html><body><p><table id=""foo""><tr><th>hello</th></tr><tr><td>world</td></tr></table></body></html>");
var table = doc.DocumentNode.SelectSingleNode("//table");
var tableRows = table.SelectNodes("tr");
var columns = tableRows[0].SelectNodes("th/text()");
for (int i = 1; i < tableRows.Count; i++)
{
    for (int e = 0; e < columns.Count; e++)
    {
        var value = tableRows[i].SelectSingleNode($"td[{e + 1}]");
        Console.Write(columns[e].InnerText + ":" + value.InnerText);
    }
Console.WriteLine();
}

os.path.getsize(path)

Return the size, in bytes, of path. Raise os.error if the file does not exist or is inaccessible.

                .Property(b => b.Timestamp)
                .ValueGeneratedOnAddOrUpdate()
                .IsConcurrencyToken()
                .ForSqliteHasDefaultValueSql("CURRENT_TIMESTAMP");

It will make a default value to every data that will be insert into this table.

Here is the Swift 5 version:

let delegate = UIApplication.shared.delegate as? AppDelegate

And to access the managed object context:

    if let delegate = UIApplication.shared.delegate as? AppDelegate {

        let moc = delegate.managedObjectContext
        
        // your code here
        
    }

or, using guard:

    guard let delegate = UIApplication.shared.delegate as? AppDelegate  else {
        return
    }

    let moc = delegate.managedObjectContext
        
    // your code here
    

The default locations of Chrome's profile directory are defined at http://www.chromium.org/user-experience/user-data-directory. For Chrome on Mac, it's

~/Library/Application\ Support/Google/Chrome/Default

The actual location can be different, by setting the --user-data-dir=path/to/directory flag.
If only one user is registered in Chrome, look in the Default/Extensions subdirectory. Otherwise, look in the <profile user name>/Extensions directory.

If that didn't help, you can always do a custom search.

1. Go to chrome://extensions/, and find out the ID of an extension (32 lowercase letters) (if not done already, activate "Developer mode" first).

   

2. Open the terminal, cd to the directory which is most likely a parent of your Chrome profile (if unsure, try ~ then /).

3. Run find . -type d -iname "<EXTENSION ID HERE>", for example:

   find . -type d -iname jifpbeccnghkjeaalbbjmodiffmgedin
   

   Result:

   

In my case, my array was multidimensional, potentially with arrays as values. So I created this recursive function to blow apart the array completely:

function array2csv($array, &$title, &$data) {
    foreach($array as $key => $value) {      
        if(is_array($value)) {
            $title .= $key . ",";
            $data .= "" . ",";
            array2csv($value, $title, $data);
        } else {
            $title .= $key . ",";
            $data .= '"' . $value . '",';
        }
    }
}

Since the various levels of my array didn't lend themselves well to a the flat CSV format, I created a blank column with the sub-array's key to serve as a descriptive "intro" to the next level of data. Sample output:

agentid     fname           lname      empid    totals  sales   leads   dish    dishnet top200_plus top120  latino  base_packages
G-adriana   ADRIANA EUGENIA PALOMO PAIZ 886                0    19              0         0         0         0      0

You could easily remove that "intro" (descriptive) column, but in my case I had repeating column headers, i.e. inbound_leads, in each sub-array, so that gave me a break/title preceding the next section. Remove:

$title .= $key . ",";
$data .= "" . ",";

after the is_array() to compact the code further and remove the extra column.

Since I wanted both a title row and data row, I pass two variables into the function and upon completion of the call to the function, terminate both with PHP_EOL:

$title .= PHP_EOL;
$data .= PHP_EOL;

Yes, I know I leave an extra comma, but for the sake of brevity, I didn't handle it here.

Oldest:

oldest = min(datetimes)

Youngest before now:

now = datetime.datetime.now(pytz.utc)
youngest = max(dt for dt in datetimes if dt < now)

java.lang.StringBuilder. Use int constructor to create an initial size.

try this.

var host = Dns.GetHostEntry(Dns.GetHostName());
        foreach (var ip in host.AddressList)
        {
            if (ip.AddressFamily == AddressFamily.InterNetwork)
            {
                 ipAddress = ip.ToString();
            }
        }

Use jquery attr method. It works in all browsers.

var hiddenInput = document.createElement("input");
$(hiddenInput).attr({
    'id':'uniqueIdentifier',
    'type': 'hidden',
    'value': ID,
    'class': 'ListItem'
});

Or you could use folowing code:

var e = $('<input id = "uniqueIdentifier" type="hidden" value="' + ID + '" class="ListItem" />');

Here is an example:

Via css:

<style>
  .my-table {
    page-break-before: always;
    page-break-after: always;
  }
  .my-table tr {
    page-break-inside: avoid;
  }
</style>

or directly on the element:

<table style="page-break-before: always; page-break-after: always;">
  <tr style="page-break-inside: avoid;">
    ..
  </tr>
</table>

I write below code to remove the blank value in the array string.

string[] test={"1","","2","","3"};
test= test.Except(new List<string> { string.Empty }).ToArray();

Supposing you have the following file structure:

-css
  --index.css
-images
  --image1.png
  --image2.png
  --image3.png

In CSS you can access image1, for example, using the line ../images/image1.png.

NOTE: If you are using Chrome, it may doesn't work and you will get an error that the file could not be found. I had the same problem, so I just deleted the entire cache history from chrome and it worked.

For me it worked to add the phrase "explicit_defaults_for_timestamp = ON" without quotes into the config file my.ini.

Make sure you add this phrase right underneath the [mysqld] statement in the config file.

You will find my.ini under C:\ProgramData\MySQL\MySQL Server 5.7 if you had conducted the default installation of MySQL.

You can achieve this by utilizing the jsPDF library and the toDataURL function.

Simple, just use .set_color

>>> barlist=plt.bar([1,2,3,4], [1,2,3,4])
>>> barlist[0].set_color('r')
>>> plt.show()

For your new question, not much harder either, just need to find the bar from your axis, an example:

>>> f=plt.figure()
>>> ax=f.add_subplot(1,1,1)
>>> ax.bar([1,2,3,4], [1,2,3,4])
<Container object of 4 artists>
>>> ax.get_children()
[<matplotlib.axis.XAxis object at 0x6529850>, 
 <matplotlib.axis.YAxis object at 0x78460d0>,  
 <matplotlib.patches.Rectangle object at 0x733cc50>, 
 <matplotlib.patches.Rectangle object at 0x733cdd0>, 
 <matplotlib.patches.Rectangle object at 0x777f290>, 
 <matplotlib.patches.Rectangle object at 0x777f710>, 
 <matplotlib.text.Text object at 0x7836450>, 
 <matplotlib.patches.Rectangle object at 0x7836390>, 
 <matplotlib.spines.Spine object at 0x6529950>, 
 <matplotlib.spines.Spine object at 0x69aef50>,
 <matplotlib.spines.Spine object at 0x69ae310>, 
 <matplotlib.spines.Spine object at 0x69aea50>]
>>> ax.get_children()[2].set_color('r') 
 #You can also try to locate the first patches.Rectangle object 
 #instead of direct calling the index.

If you have a complex plot and want to identify the bars first, add those:

>>> import matplotlib
>>> childrenLS=ax.get_children()
>>> barlist=filter(lambda x: isinstance(x, matplotlib.patches.Rectangle), childrenLS)
[<matplotlib.patches.Rectangle object at 0x3103650>, 
 <matplotlib.patches.Rectangle object at 0x3103810>, 
 <matplotlib.patches.Rectangle object at 0x3129850>, 
 <matplotlib.patches.Rectangle object at 0x3129cd0>, 
 <matplotlib.patches.Rectangle object at 0x3112ad0>]

From the documentation for scatter:

Optional kwargs control the Collection properties; in particular:

    edgecolors:
        The string ‘none’ to plot faces with no outlines
    facecolors:
        The string ‘none’ to plot unfilled outlines

Try the following:

import matplotlib.pyplot as plt 
import numpy as np 

x = np.random.randn(60) 
y = np.random.randn(60)

plt.scatter(x, y, s=80, facecolors='none', edgecolors='r')
plt.show()

Note: For other types of plots see this post on the use of markeredgecolor and markerfacecolor.

Just to add more to comment

Mainly about how to do performance testing.

I did testing with following code:

import (
    "testing"
)

var ss = []string{"Hello", "", "bar", " ", "baz", "ewrqlosakdjhf12934c r39yfashk fjkashkfashds fsdakjh-", "", "123"}

func BenchmarkStringCheckEq(b *testing.B) {
    c := 0
    b.ResetTimer()
    for n := 0; n < b.N; n++ {
            for _, s := range ss {
                    if s == "" {
                            c++
                    }
            }
    } 
    t := 2 * b.N
    if c != t {
            b.Fatalf("did not catch empty strings: %d != %d", c, t)
    }
}
func BenchmarkStringCheckLen(b *testing.B) {
    c := 0
    b.ResetTimer()
    for n := 0; n < b.N; n++ {
            for _, s := range ss { 
                    if len(s) == 0 {
                            c++
                    }
            }
    } 
    t := 2 * b.N
    if c != t {
            b.Fatalf("did not catch empty strings: %d != %d", c, t)
    }
}
func BenchmarkStringCheckLenGt(b *testing.B) {
    c := 0
    b.ResetTimer()
    for n := 0; n < b.N; n++ {
            for _, s := range ss {
                    if len(s) > 0 {
                            c++
                    }
            }
    } 
    t := 6 * b.N
    if c != t {
            b.Fatalf("did not catch empty strings: %d != %d", c, t)
    }
}
func BenchmarkStringCheckNe(b *testing.B) {
    c := 0
    b.ResetTimer()
    for n := 0; n < b.N; n++ {
            for _, s := range ss {
                    if s != "" {
                            c++
                    }
            }
    } 
    t := 6 * b.N
    if c != t {
            b.Fatalf("did not catch empty strings: %d != %d", c, t)
    }
}

And results were:

Effectively variants usually do not reach fastest time and there is only minimal difference (about 0.01ns/op) between variant top speed.

And if I look full log, difference between tries is greater than difference between benchmark functions.

Also there does not seem to be any measurable difference between BenchmarkStringCheckEq and BenchmarkStringCheckNe or BenchmarkStringCheckLen and BenchmarkStringCheckLenGt even if latter variants should inc c 6 times instead of 2 times.

You can try to get some confidence about equal performance by adding tests with modified test or inner loop. This is faster:

func BenchmarkStringCheckNone4(b *testing.B) {
    c := 0
    b.ResetTimer()
    for n := 0; n < b.N; n++ {
            for _, _ = range ss {
                    c++
            }
    }
    t := len(ss) * b.N
    if c != t {
            b.Fatalf("did not catch empty strings: %d != %d", c, t)
    }
}

This is not faster:

func BenchmarkStringCheckEq3(b *testing.B) {
    ss2 := make([]string, len(ss))
    prefix := "a"
    for i, _ := range ss {
            ss2[i] = prefix + ss[i]
    }
    c := 0
    b.ResetTimer()
    for n := 0; n < b.N; n++ {
            for _, s := range ss2 {
                    if s == prefix {
                            c++
                    }
            }
    }
    t := 2 * b.N
    if c != t {
            b.Fatalf("did not catch empty strings: %d != %d", c, t)
    }
}

Both variants are usually faster or slower than difference between main tests.

It would also good to generate test strings (ss) using string generator with relevant distribution. And have variable lengths too.

So I don't have any confidence of performance difference between main methods to test empty string in go.

And I can state with some confidence, it is faster not to test empty string at all than test empty string. And also it is faster to test empty string than to test 1 char string (prefix variant).

Alternatively to the trick of triggering the parallel computation inside your own forkJoinPool you can also pass that pool to the CompletableFuture.supplyAsync method like in:

ForkJoinPool forkJoinPool = new ForkJoinPool(2);
CompletableFuture<List<Integer>> primes = CompletableFuture.supplyAsync(() ->
    //parallel task here, for example
    range(1, 1_000_000).parallel().filter(PrimesPrint::isPrime).collect(toList()), 
    forkJoinPool
);

I struggled with this issue for a long time... My solution was to modify the php.ini file, in the folder that contained the php script. This was important, as modifying the php.ini at the root did not resolve the problem (I have a php.ini in each folder for granular control). The relevant entries in my php.ini looked like this.... (the output_buffering is not likely needed for this issue)

output_buffering = On 
upload_max_filesize = 20M 
post_max_size = 21M

check this one out.

<input type="text" name="firstname">
<input type="text" name="lastname">
<input type="text" name="email">
<input type="text" name="address">

<input type="text" name="tree[tree1][height]">

<input type="text" name="tree[tree2][fruit]">
<input type="text" name="tree[tree2][height]">

<input type="text" name="tree[tree3][fruit]">
<input type="text" name="tree[tree3][height]">

it should end up like this in the $_POST[] array (PHP format for easy visualization)

$_POST[] = array(
    'firstname'=>'value',
    'lastname'=>'value',
    'email'=>'value',
    'address'=>'value',
    'tree' => array(
        'tree1'=>array(
            'fruit'=>'value',
            'height'=>'value'
        ),
        'tree2'=>array(
            'fruit'=>'value',
            'height'=>'value'
        ),
        'tree3'=>array(
            'fruit'=>'value',
            'height'=>'value'
        )
    )
)

I bet the onchange is getting fired after the onselect, essentially re-enabling the select.

I'd recommend you implement only the onchange, inspect which option has been selected, and enable or disabled based on that.

To get the value of the selected option use:

document.getElementById("mySelect").options[document.getElementById("mySelect").selectedIndex].value

Which will yield .. nothing since you haven't specified a value for each option .. :(

<select id="mySelect" onChange="enable();">
<option onSelect="disable();" value="no">No</option>
<option onSelect="enable();" value="yes">Yes</option>
</select>

Now it will yield "yes" or "no"

by using DockerFile, I'm copying agent and lib directories to /apps/agent,/apps/lib directories and bunch of files to target.

var otherInput = $(this).closest('.row').find('.inputQty');

That goes up to a row level, then back down to .inputQty.

After copying my local repository and working copy to another folder (on Windows by the way), I had four files that kept showing up as changed and tried every suggestion listed in the other answers. In the end what fixed it for me was deleting the local branch and downloading it again from the remote. In my case I guess it had something to do with copying a local repository rather than cloning.

Variable number of arguments

It is possible to pass a variable number of arguments to a method. However, there are some restrictions:

• The variable number of parameters must all be the same type
• They are treated as an array within the method
• They must be the last parameter of the method

To understand these restrictions, consider the method, in the following code snippet, used to return the largest integer in a list of integers:

private static int largest(int... numbers) {
     int currentLargest = numbers[0];
     for (int number : numbers) {
        if (number > currentLargest) {
            currentLargest = number;
        }
     }
     return currentLargest;
}

thead {
  position: fixed;
  height: 10px; /* This is whatever height you want */
}
  tbody {
  position: fixed;
  margin-top: 10px; /* This has to match the height of thead */
  height: 300px; /* This is whatever height you want */
}

I haven't tried it but if you put a div in your table cell set so that it will have scrollbars if needed, then you could insert in there, with a fixed height on the div and it should keep your table row to a fixed height.
