Programs & Examples On #Auth token

A POST with httpClient in Angular 6 was also doing an OPTIONS request:

Headers General:

Request URL:https://hp-probook/perl-bin/muziek.pl/=/postData
Request Method:OPTIONS
Status Code:200 OK
Remote Address:127.0.0.1:443
Referrer Policy:no-referrer-when-downgrade

My Perl REST server implements the OPTIONS request with return code 200.

The next POST request Header:

Accept:*/*
Accept-Encoding:gzip, deflate, br
Accept-Language:nl-NL,nl;q=0.8,en-US;q=0.6,en;q=0.4
Access-Control-Request-Headers:content-type
Access-Control-Request-Method:POST
Connection:keep-alive
Host:hp-probook
Origin:http://localhost:4200
Referer:http://localhost:4200/
User-Agent:Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.109 Safari/537.36

Notice Access-Control-Request-Headers:content-type.

So, my backend perl script uses the following headers:

 -"Access-Control-Allow-Origin" => '*',
 -"Access-Control-Allow-Methods" => 'GET,POST,PATCH,DELETE,PUT,OPTIONS',
 -"Access-Control-Allow-Headers" => 'Origin, Content-Type, X-Auth-Token, content-type',

With this setup the GET and POST worked for me!

// https://docs.spring.io/spring-boot/docs/2.4.2/reference/htmlsingle/#boot-features-cors
@Configuration
public class MyConfiguration {

    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(final CorsRegistry registry) {
                registry.addMapping("/**").allowedMethods("*").allowedHeaders("*");
            }
        };
    }
}

If using Spring Security, set additional:

// https://docs.spring.io/spring-security/site/docs/5.4.2/reference/html5/#cors
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(final HttpSecurity http) throws Exception {
        // ...

        // if Spring MVC is on classpath and no CorsConfigurationSource is provided,
        // Spring Security will use CORS configuration provided to Spring MVC
        http.cors(Customizer.withDefaults());
    }
}

Step 1

By annotating the controller with @CrossOrigin annotation will allow the CORS configurations.

@CrossOrigin
@RestController
public class SampleController { 
  .....
}

Step 2

Spring already has a CorsFilter even though You can just register your own CorsFilter as a bean to provide your own configuration as follows.

@Bean
public CorsFilter corsFilter() {
    final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    final CorsConfiguration config = new CorsConfiguration();
    config.setAllowedOrigins(Collections.singletonList("http://localhost:3000")); // Provide list of origins if you want multiple origins
    config.setAllowedHeaders(Arrays.asList("Origin", "Content-Type", "Accept"));
    config.setAllowedMethods(Arrays.asList("GET", "POST", "PUT", "OPTIONS", "DELETE", "PATCH"));
    config.setAllowCredentials(true);
    source.registerCorsConfiguration("/**", config);
    return new CorsFilter(source);
}

I faced the same problem here's the solution:(Explained)

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
        .authorizeRequests()
            .antMatchers(HttpMethod.POST,"/form").hasRole("ADMIN")  // Specific api method request based on role.
            .antMatchers("/home","/basic").permitAll()  // permited urls to guest users(without login).
            .anyRequest().authenticated()
            .and()
        .formLogin()       // not specified form page to use default login page of spring security.
            .permitAll()
             .and()
        .logout().deleteCookies("JSESSIONID")  // delete memory of browser after logout.

        .and()
        .rememberMe().key("uniqueAndSecret"); // remember me check box enabled.

    http.csrf().disable();  **// ADD THIS CODE TO DISABLE CSRF IN PROJECT.**
}

for me one solution for this problem was to add in sql.Open ... sslmode=disable

Put your script in a file foo.py starting with

#!/usr/bin/python

Then give execute permission to that script using

chmod a+x foo.py

and use the full path of your foo.py file in your crontab.

See documentation of execve(2) which is handling the shebang.

First of all, you should make an HTML form containing a file input element. You also need to set the form's enctype attribute to multipart/form-data:

<form method="post" enctype="multipart/form-data" action="/upload">
    <input type="file" name="file">
    <input type="submit" value="Submit">
</form>

Assuming the form is defined in index.html stored in a directory named public relative to where your script is located, you can serve it this way:

const http = require("http");
const path = require("path");
const fs = require("fs");

const express = require("express");

const app = express();
const httpServer = http.createServer(app);

const PORT = process.env.PORT || 3000;

httpServer.listen(PORT, () => {
  console.log(`Server is listening on port ${PORT}`);
});

// put the HTML file containing your form in a directory named "public" (relative to where this script is located)
app.get("/", express.static(path.join(__dirname, "./public")));

Once that's done, users will be able to upload files to your server via that form. But to reassemble the uploaded file in your application, you'll need to parse the request body (as multipart form data).

In Express 3.x you could use express.bodyParser middleware to handle multipart forms but as of Express 4.x, there's no body parser bundled with the framework. Luckily, you can choose from one of the many available multipart/form-data parsers out there. Here, I'll be using multer:

You need to define a route to handle form posts:

const multer = require("multer");

const handleError = (err, res) => {
  res
    .status(500)
    .contentType("text/plain")
    .end("Oops! Something went wrong!");
};

const upload = multer({
  dest: "/path/to/temporary/directory/to/store/uploaded/files"
  // you might also want to set some limits: https://github.com/expressjs/multer#limits
});


app.post(
  "/upload",
  upload.single("file" /* name attribute of <file> element in your form */),
  (req, res) => {
    const tempPath = req.file.path;
    const targetPath = path.join(__dirname, "./uploads/image.png");

    if (path.extname(req.file.originalname).toLowerCase() === ".png") {
      fs.rename(tempPath, targetPath, err => {
        if (err) return handleError(err, res);

        res
          .status(200)
          .contentType("text/plain")
          .end("File uploaded!");
      });
    } else {
      fs.unlink(tempPath, err => {
        if (err) return handleError(err, res);

        res
          .status(403)
          .contentType("text/plain")
          .end("Only .png files are allowed!");
      });
    }
  }
);

In the example above, .png files posted to /upload will be saved to uploaded directory relative to where the script is located.

In order to show the uploaded image, assuming you already have an HTML page containing an img element:

<img src="/image.png" />

you can define another route in your express app and use res.sendFile to serve the stored image:

app.get("/image.png", (req, res) => {
  res.sendFile(path.join(__dirname, "./uploads/image.png"));
});

A different approach that I found ugly compared to the classic dict+append, but that works:

df = df.T

df[0] = ['1/1/2013', 'Smith','test',123]

df = df.T

df
Out[6]: 
       Date   Name Action   ID
0  1/1/2013  Smith   test  123

For MySQL, MariaDB

ALTER TABLE [table name] MODIFY COLUMN [column name] [data type] NULL

Use MODIFY COLUMN instead of ALTER COLUMN.

Often i reach for the abbreviation html tag in this situation.

<abbr title="Hover">Text</abbr>

https://www.w3schools.com/tags/tag_abbr.asp

To ignore loop references and not to serialize them globally in MVC 6 use the following in startup.cs:

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc().Configure<MvcOptions>(options =>
        {
            options.OutputFormatters.RemoveTypesOf<JsonOutputFormatter>();
            var jsonOutputFormatter = new JsonOutputFormatter();
            jsonOutputFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
            options.OutputFormatters.Insert(0, jsonOutputFormatter);
        });
    }

That is not possible. Reading is downloading. When a user is reading a file, browser is downloading that file to temp. So even if you disable the download button, the user can click "File -> Save As" or copy that file from temp folder.

There are a few things you can do:

Method 1

The following code will embed a PDF without any toolbars and hide the print/download icons

<embed src="{URL_TO_PDF.PDF}#toolbar=0&navpanes=0&scrollbar=0" width="425" height="425">

Method 02

Using Google Drive

Right click on pdf and goto Share(below image)

Then go to Advanced option in left bottom

Tick Both check boxes. After copy embed link and paste it to your src. No download and Save drive option is not allowed

Unsigned can hold a larger positive value and no negative value.

Yes.

Unsigned uses the leading bit as a part of the value, while the signed version uses the left-most-bit to identify if the number is positive or negative.

There are different ways of representing signed integers. The easiest to visualise is to use the leftmost bit as a flag (sign and magnitude), but more common is two's complement. Both are in use in most modern microprocessors — floating point uses sign and magnitude, while integer arithmetic uses two's complement.

Signed integers can hold both positive and negative numbers.

Yes.

You can use:

@foreach (var item in Model)
{
  ...
  @Html.DisplayFor(modelItem => item.address + " " + item.city) 
  ...

use datejs

new Date().toString('yyyy-MM-d-h-mm-ss');

There are two ways to get the length of "something" on a computer.

The first way is to store a count - this requires anything that touches the file/data to modify it (or a class that only exposes interfaces -- but it boils down to the same thing).

The other way is to iterate over it and count how big it is.

Assuming array is a character array that does not end in \0, you will want to use strncpy:

char * strncpy(char * destination, const char * source, size_t num);

like so:

strncpy(string, array, 20);
string[20] = '\0'

Then string will be a null terminated C string, as desired.

You need to use cv.LoadImageM instead of cv.LoadImage:

In [1]: import cv
In [2]: import numpy as np
In [3]: x = cv.LoadImageM('im.tif')
In [4]: im = np.asarray(x)
In [5]: im.shape
Out[5]: (487, 650, 3)

Using alias for referencing the tables to get the columns from different tables after joining them.

Select tb1.*, tb2.col1, tb2.col2 from table1 tb1 JOIN table2 tb2 on tb1.Id = tb2.Id

-- If no parameters need to be passed to a procedure, simply:

BEGIN
   MY_PACKAGE_NAME.MY_PROCEDURE_NAME
END;

Here's how I think you make a POST request with data and a cookie using just the node http library. This example is posting JSON, set your content-type and content-length accordingly if you post different data.

// NB:- node's http client API has changed since this was written
// this code is for 0.4.x
// for 0.6.5+ see http://nodejs.org/docs/v0.6.5/api/http.html#http.request

var http = require('http');

var data = JSON.stringify({ 'important': 'data' });
var cookie = 'something=anything'

var client = http.createClient(80, 'www.example.com');

var headers = {
    'Host': 'www.example.com',
    'Cookie': cookie,
    'Content-Type': 'application/json',
    'Content-Length': Buffer.byteLength(data,'utf8')
};

var request = client.request('POST', '/', headers);

// listening to the response is optional, I suppose
request.on('response', function(response) {
  response.on('data', function(chunk) {
    // do what you do
  });
  response.on('end', function() {
    // do what you do
  });
});
// you'd also want to listen for errors in production

request.write(data);

request.end();

What you send in the Cookie value should really depend on what you received from the server. Wikipedia's write-up of this stuff is pretty good: http://en.wikipedia.org/wiki/HTTP_cookie#Cookie_attributes

Could anyone help explain why

In Python 2 a python "int" was equivalent to a C long. In Python 3 an "int" is an arbitrary precision type but numpy still uses "int" it to represent the C type "long" when creating arrays.

The size of a C long is platform dependent. On windows it is always 32-bit. On unix-like systems it is normally 32 bit on 32 bit systems and 64 bit on 64 bit systems.

or give a solution for the code on windows? Thanks so much!

Choose a data type whose size is not platform dependent. You can find the list at https://docs.scipy.org/doc/numpy/reference/arrays.scalars.html#arrays-scalars-built-in the most sensible choice would probably be np.int64

There is also direct support for white space removal in Bash variable substitution:

testvar=$(wc -l < log.txt)
trailing_space_removed=${testvar%%[[:space:]]}
leading_space_removed=${testvar##[[:space:]]}

Underscore-java library can convert json string to hash map. I am the maintainer of the project.

Code example:

import com.github.underscore.lodash.U;
import java.util.*;

public class Main {

    @SuppressWarnings("unchecked")
    public static void main(String[] args) {
        String json = "{"
            + "    \"data\" :"
            + "    {"
            + "        \"field1\" : \"value1\","
            + "        \"field2\" : \"value2\""
            + "    }"
            + "}";

       Map<String, Object> data = (Map) U.get((Map<String, Object>) U.fromJson(json), "data");
       System.out.println(data);

       // {field1=value1, field2=value2}
    }
}

I found a solution for this problem. The issue I described in my question occured basically due to the incompatibility of the Microsoft.Jet.OLEDB.4.0 driver in 64 bit OS.

So if we are using Microsoft.Jet.OLEDB.4.0 driver in a 64 bit server, we have to force our application to build in in 32 bit mode (This is the answer I found when I did an extensive search for this known issue) and that causes other part of my code to break.

Fortunately, now Microsoft has released a 64 bit compatible 2010 Office System Driver which can be used as replacement for the traditional Microsoft.Jet.OLEDB.4.0 driver. It works both in 32 bit as well as 64 bit servers. I have used it for Excel file manipulation and it worked fine for me in both the environments. But this driver is in BETA.

You can download this driver from Microsoft Access Database Engine 2010 Redistributable

you could use "AUTHID CURRENT_USER" in body of your procedure definition for your requirements.

You would need to attach your click event to some element. If there are lots of other elements on the page you would not want to attach a click event to all of them.

One potential way would be to create a transparent div below your dropdown menu but above all other elements on the page. You would show it when the drop down was shown. Have the element have a click hander that hides the drop down and the transparent div.

$('#clickCatcher').click(function () { _x000D_
  $('#dropContainer').hide();_x000D_
  $(this).hide();_x000D_
});

#dropContainer { z-index: 101; ... }_x000D_
#clickCatcher { position: absolute; top: 0; left: 0; width: 100%; height: 100%; z-index: 100; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="dropDown"></div>_x000D_
<div id="clickCatcher"></div>

Consistency is the key to any naming standard. As long as it's logical and consistent, you're 99% there.

The standard itself is very much personal preference - so if you like your standard, then run with it.

To answer your question outright - no, MySQL doesn't have a preferred naming convention/standard, so rolling your own is fine (and yours seems logical).

Simply you can change any activity name by using

Activityname.this.setTitle("Title Name");

    public void ProcessRequest(HttpContext context)
    {
        string constring = ConfigurationManager.ConnectionStrings["SQL_Connection_String"].ConnectionString;
        SqlConnection conn = new SqlConnection(constring);
        conn.Open();
        SqlCommand cmd = new SqlCommand("select image1 from TestGo where TestId=1", conn);
        SqlDataReader dr = cmd.ExecuteReader();
        dr.Read();
        MemoryStream str = new MemoryStream();

        context.Response.Clear();
        Byte[] bytes = (Byte[])dr[0];
        string d = System.Text.Encoding.Default.GetString(bytes);
        byte[] bytes2 = Convert.FromBase64String(d);
        //context.Response.Write(d);
        Image img = Image.FromStream(new MemoryStream(bytes2));
        img.Save(context.Response.OutputStream, ImageFormat.Png);
        context.Response.Flush();
        str.WriteTo(context.Response.OutputStream);
        str.Dispose();
        str.Close();
        conn.Close();
        context.Response.End();
    }

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

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

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

j_obj = json.load(j)

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

UPDATE  table
SET     columnx = CASE WHEN condition THEN 25 ELSE columnx END,
        columny = CASE WHEN condition THEN columny ELSE 25 END

Here is a resource you can edit and use Download Source Code or see live demo here http://purpledesign.in/blog/pop-out-a-form-using-jquery-and-javascript/

Add a Button or link to your page like this

<p><a href="#inline">click to open</a></p>

“#inline” here should be the “id” of the that will contain the form.

<div id="inline">
 <h2>Send us a Message</h2>
 <form id="contact" name="contact" action="#" method="post">
 <label for="email">Your E-mail</label>
 <input type="email" id="email" name="email" class="txt">
 <br>
 <label for="msg">Enter a Message</label>
 <textarea id="msg" name="msg" class="txtarea"></textarea>
<button id="send">Send E-mail</button>
 </form>
</div>

Include these script to listen of the event of click. If you have an action defined in your form you can use “preventDefault()” method

<script type="text/javascript">
 $(document).ready(function() {
$(".modalbox").fancybox();
$("#contact").submit(function() { return false; });
$("#send").on("click", function(){
var emailval = $("#email").val();
var msgval = $("#msg").val();
var msglen = msgval.length;
var mailvalid = validateEmail(emailval);
if(mailvalid == false) {
$("#email").addClass("error");
}
else if(mailvalid == true){
 $("#email").removeClass("error");
 }

 if(msglen < 4) {
 $("#msg").addClass("error");
 }
 else if(msglen >= 4){
 $("#msg").removeClass("error");
 }

 if(mailvalid == true && msglen >= 4) {
 // if both validate we attempt to send the e-mail
 // first we hide the submit btn so the user doesnt click twice
 $("#send").replaceWith("<em>sending...</em>");
 //This will post it to the php page
 $.ajax({
 type: 'POST',
 url: 'sendmessage.php',
 data: $("#contact").serialize(),
 success: function(data) {
 if(data == "true") {
 $("#contact").fadeOut("fast", function(){
//Display a message on successful posting for 1 sec
 $(this).before("<p><strong>Success! Your feedback has been sent, thanks :)</strong></p>");
 setTimeout("$.fancybox.close()", 1000);
 });
 }
 }
 });
 }
 });
 });
</script>

You can add anything you want to do in your PHP file.

Some time when we use Environ() function we may get the Library or property not found error. Use VBA.Environ() or VBA.Environ$() to avoid the error.

Content-Type: application/force-download means "I, the web server, am going to lie to you (the browser) about what this file is so that you will not treat it as a PDF/Word Document/MP3/whatever and prompt the user to save the mysterious file to disk instead". It is a dirty hack that breaks horribly when the client doesn't do "save to disk".

Use the correct mime type for whatever media you are using (e.g. audio/mpeg for mp3).

Use the Content-Disposition: attachment; etc etc header if you want to encourage the client to download it instead of following the default behaviour.

Using subList(30, 38); will fail because max index 38 is not available in list, so its not possible.

Only way may be before asking for the sublist, you explicitly determine the max index using list size() method.

for example, check size, which returns 35, so call sublist(30, size());

OR

COPIED FROM pb2q comment

dataList = dataList.subList(30, 38 > dataList.size() ? dataList.size() : 38);

I am a totally blind college student who’s had several programming internships so my answer will be based off these. I use windows xp as my operating system and Jaws to read what appears on the screen to me in synthetic speech. For java programming I use eclipse, since it’s a fully featured IDE that is accessible.

In my experience as a general rule java programs that use SWT as the GUI toolkit are more accessible then programs that use Swing which is why I stay away from netbeans. For any .net programming I use visual studio 2005 since it was the standard version used at my internship and is very accessible using Jaws and a set of scripts that were developed to make things such as the form designer more accessible.

For C and C++ programming I use cygwin with gcc as my compiler and emacs or vim as my editor depending on what I need to do. A lot of my internship involved programming for Z/OS. I used an rlogin session through Cygwin to access the USS subsystem on the mainframe and C3270 as my 3270 emulator to access the ISPF portion of the mainframe.

I usually rely on synthetic speech but do have a Braille display. I find I usually work faster with speech but use the Braille display in situations where punctuation matters and gets complicated. Examples of this are if statements with lots of nested parenthesis’s and JCL where punctuation is incredibly important.

Update

I'm playing with Emacspeak under cygwin http://emacspeak.sourceforge.net I'm not sure if this will be usable as a programming editor since it appears to be somewhat unresponsive but I haven't looked at any of the configuration options yet.

Just add below code and you are good to go.

You can use pandas.Dataframe.isin.

pandas.Dateframe.isin will return boolean values depending on whether each element is inside the list a or not. You then invert this with the ~ to convert True to False and vice versa.

import pandas as pd

a = ['2015-01-01' , '2015-02-01']

df = pd.DataFrame(data={'date':['2015-01-01' , '2015-02-01', '2015-03-01' , '2015-04-01', '2015-05-01' , '2015-06-01']})

print(df)
#         date
#0  2015-01-01
#1  2015-02-01
#2  2015-03-01
#3  2015-04-01
#4  2015-05-01
#5  2015-06-01

df = df[~df['date'].isin(a)]

print(df)
#         date
#2  2015-03-01
#3  2015-04-01
#4  2015-05-01
#5  2015-06-01

Acked Unseen sample

Hi guys! Just some observations from what I just found in my capture:

On many occasions, the packet capture reports “ACKed segment that wasn't captured” on the client side, which alerts of the condition that the client PC has sent a data packet, the server acknowledges receipt of that packet, but the packet capture made on the client does not include the packet sent by the client

Initially, I thought it indicates a failure of the PC to record into the capture a packet it sends because “e.g., machine which is running Wireshark is slow” (https://osqa-ask.wireshark.org/questions/25593/tcp-previous-segment-not-captured-is-that-a-connectivity-issue)
However, then I noticed every time I see this “ACKed segment that wasn't captured” alert I can see a record of an “invalid” packet sent by the client PC

• In the capture example above, frame 67795 sends an ACK for 10384

• Even though wireshark reports Bogus IP length (0), frame 67795 is reported to have length 13194

• Frame 67800 sends an ACK for 23524
• 10384+13194 = 23578
• 23578 – 23524 = 54
• 54 is in fact length of the Ethernet / IP / TCP headers (14 for Ethernt, 20 for IP, 20 for TCP)
• So in fact, the frame 67796 does represent a large TCP packets (13194 bytes) which operating system tried to put on the wore
  • NIC driver will fragment it into smaller 1500 bytes pieces in order to transmit over the network
  • But Wireshark running on my PC fails to understand it is a valid packet and parse it. I believe Wireshark running on 2012 Windows server reads these captures correctly
• So after all, these “Bogus IP length” and “ACKed segment that wasn't captured” alerts were in fact false positives in my case

have a look at the php documentation for theese functions you can send post reqeust using them.

fsockopen()
fputs()

or simply use a class like Zend_Http_Client which is also based on socket-conenctions.

also found a neat example using google...

This generally raises when the client sends a burst of requests to the server, next to a client side event.

This is generally a sign of "bad" programming in client side.

Imagine I am updating all lines of a table.

The bad way is to send a request to update each row (many requests in rafale without waiting for request complete). To correct it , be sure, the request is complete, before sending another one.

The good way would be to send a request with all updated rows. (one request)

So, at first, look at what is happening client side and refactoring code if necessary.

Use wireshark to identify what goes wrong in requests.

I was able to accomplish this with VBA in Excel 2013. No special editors needed. All you need is the Visual Basic code editor which can be accessed on the Developer tab. The Developer tab is not visible by default so it needs to be enabled in File>Options>Customize Ribbon. On the Developer tab, click the Visual Basic button. The code editor will launch. Right click in the Project Explorer pane on the left. Click the insert menu and choose module. Add both subs below to the new module.

Sub LoadCustRibbon()

Dim hFile As Long
Dim path As String, fileName As String, ribbonXML As String, user As String

hFile = FreeFile
user = Environ("Username")
path = "C:\Users\" & user & "\AppData\Local\Microsoft\Office\"
fileName = "Excel.officeUI"

ribbonXML = "<mso:customUI      xmlns:mso='http://schemas.microsoft.com/office/2009/07/customui'>" & vbNewLine
ribbonXML = ribbonXML + "  <mso:ribbon>" & vbNewLine
ribbonXML = ribbonXML + "    <mso:qat/>" & vbNewLine
ribbonXML = ribbonXML + "    <mso:tabs>" & vbNewLine
ribbonXML = ribbonXML + "      <mso:tab id='reportTab' label='Reports' insertBeforeQ='mso:TabFormat'>" & vbNewLine
ribbonXML = ribbonXML + "        <mso:group id='reportGroup' label='Reports' autoScale='true'>" & vbNewLine
ribbonXML = ribbonXML + "          <mso:button id='runReport' label='PTO' "   & vbNewLine
ribbonXML = ribbonXML + "imageMso='AppointmentColor3'      onAction='GenReport'/>" & vbNewLine
ribbonXML = ribbonXML + "        </mso:group>" & vbNewLine
ribbonXML = ribbonXML + "      </mso:tab>" & vbNewLine
ribbonXML = ribbonXML + "    </mso:tabs>" & vbNewLine
ribbonXML = ribbonXML + "  </mso:ribbon>" & vbNewLine
ribbonXML = ribbonXML + "</mso:customUI>"

ribbonXML = Replace(ribbonXML, """", "")

Open path & fileName For Output Access Write As hFile
Print #hFile, ribbonXML
Close hFile

End Sub

Sub ClearCustRibbon()

Dim hFile As Long
Dim path As String, fileName As String, ribbonXML As String, user As String

hFile = FreeFile
user = Environ("Username")
path = "C:\Users\" & user & "\AppData\Local\Microsoft\Office\"
fileName = "Excel.officeUI"

ribbonXML = "<mso:customUI           xmlns:mso=""http://schemas.microsoft.com/office/2009/07/customui"">" & _
"<mso:ribbon></mso:ribbon></mso:customUI>"

Open path & fileName For Output Access Write As hFile
Print #hFile, ribbonXML
Close hFile

End Sub

Call LoadCustRibbon sub in the Wookbook open even and call the ClearCustRibbon sub in the Before_Close Event of the ThisWorkbook code file.

I was also stuck on the same kind of problem and I followed the simple steps below.

Just get the exact url of the file to which you want to copy, for example:

http://www.test.com/test.txt (file to copy)

Then pass the exact absolute folder path with filename where you do want to write that file.

1. If you are on a Windows machine then d:/xampp/htdocs/upload/test.txt

2. If you are on a Linux machine then /var/www/html/upload/test.txt

You can get the document root with the PHP function $_SERVER['DOCUMENT_ROOT'].

I was able to make parent window disable. However making the pop-up always keep raised didn't work. Below code works even for frame tags. Just add id and class property to frame tag and it works well there too.

In parent window use:

<head>    
<style>
.disableWin{
     pointer-events: none;
}
</style>
<script type="text/javascript">
    function openPopUp(url) {
      disableParentWin(); 
      var win = window.open(url);
      win.focus();
      checkPopUpClosed(win);
    }
    /*Function to detect pop up is closed and take action to enable parent window*/
   function checkPopUpClosed(win) {
         var timer = setInterval(function() {
              if(win.closed) {
                  clearInterval(timer);                  
                  enableParentWin();
              }
          }, 1000);
     }
     /*Function to enable parent window*/ 
     function enableParentWin() {
          window.document.getElementById('mainDiv').class="";
     }
     /*Function to enable parent window*/ 
     function disableParentWin() {
          window.document.getElementById('mainDiv').class="disableWin";
     }

</script>
</head>

<body>
<div id="mainDiv class="">
</div>
</body>    

For me, the problem was the Start page -- it was downloading content and causing Visual Studio to hang.

The only solution for me was to:

1. Kill the DevEnv process from Task Manager
2. Start Visual Studio in Safe Mode from the command line:
   devenv.exe /safemode
3. Go to menu Tools → Options, and select the Environment/Startup options
4. Choose "Show empty environment" for the startup action
5. Close Visual Studio
6. Restart normally

You're already prepending the hash sign in your showDialog() function, and you're missing single quotes in your second code snippet. You should also return false from the handler to prevent a postback from occurring. Try:

<asp:Button ID="ButtonAdd" runat="server" Text="Add"
    OnClientClick="showDialog('<%=addPerson.ClientID %>'); return false;" />

You can try converting your image from tiff to PNG, here is how to do it:

import com.sun.media.jai.codec.ImageCodec;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.ImageEncoder;
import com.sun.media.jai.codec.PNGEncodeParam;
import com.sun.media.jai.codec.TIFFDecodeParam;
import java.awt.image.RenderedImage;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import javaxt.io.Image;

public class ImgConvTiffToPng {

    public static byte[] convert(byte[] tiff) throws Exception {

        byte[] out = new byte[0];
        InputStream inputStream = new ByteArrayInputStream(tiff);

        TIFFDecodeParam param = null;

        ImageDecoder dec = ImageCodec.createImageDecoder("tiff", inputStream, param);
        RenderedImage op = dec.decodeAsRenderedImage(0);

        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

        PNGEncodeParam jpgparam = null;
        ImageEncoder en = ImageCodec.createImageEncoder("png", outputStream, jpgparam);
        en.encode(op);
        outputStream = (ByteArrayOutputStream) en.getOutputStream();
        out = outputStream.toByteArray();
        outputStream.flush();
        outputStream.close();

        return out;

    }

typedef struct{
     char name[30];
     char surname[30];
     int age;
} data;

defines that data should be a block of memory that fits 60 chars plus 4 for the int (see note)

[----------------------------,------------------------------,----]
 ^ this is name              ^ this is surname              ^ this is age

This allocates the memory on the stack.

data s1;

Assignments just copies numbers, sometimes pointers.

This fails

s1.name = "Paulo";

because the compiler knows that s1.name is the start of a struct 64 bytes long, and "Paulo" is a char[] 6 bytes long (6 because of the trailing \0 in C strings)
Thus, trying to assign a pointer to a string into a string.

To copy "Paulo" into the struct at the point name and "Rossi" into the struct at point surname.

memcpy(s1.name,    "Paulo", 6);
memcpy(s1.surname, "Rossi", 6);
s1.age = 1;

You end up with

[Paulo0----------------------,Rossi0-------------------------,0001]

strcpy does the same thing but it knows about \0 termination so does not need the length hardcoded.

Alternatively you can define a struct which points to char arrays of any length.

typedef struct {
  char *name;
  char *surname;
  int age;
} data;

This will create

[----,----,----]

This will now work because you are filling the struct with pointers.

s1.name = "Paulo";
s1.surname = "Rossi";
s1.age = 1;

Something like this

[---4,--10,---1]

Where 4 and 10 are pointers.

Note: the ints and pointers can be different sizes, the sizes 4 above are 32bit as an example.

SELECT tab.*,
    row_number() OVER () as rnum
  FROM tab;

Here's the relevant section in the docs.

P.S. This, in fact, fully matches the answer in the referenced question.

Although it is not a good solution but may solve your problem. You need to use position absolute in #yellow element!

#yellow {height: 100%; background: yellow; position: absolute; top: 0px; left: 0px;}_x000D_
.container-fluid {position: static !important;}

I just found a solution that I think works really well and gets around all of the pitfalls of custom symbols. The main problem with the li:before solution is that if list-items are longer than one line will not indent properly after the first line of text. By using text-indent with a negative padding we can circumvent that problem and have all the lines aligned properly:

ul{
    padding-left: 0; // remove default padding
}

li{
    list-style-type: none;  // remove default styles
    padding-left: 1.2em;    
    text-indent:-1.2em;     // remove padding on first line
}

li::before{
    margin-right:     0.5em; 
    width:            0.7em; // margin-right and width must add up to the negative indent-value set above
    height:           0.7em;

    display:          inline-block;
    vertical-align:   middle;
    border-radius: 50%;
    background-color: orange;
    content:          ' '
}

If you ever had to support, say, Mac OS X, which doesn't have /proc/, what would you have done? Use #ifdefs to isolate the platform-specific code (NSBundle, for example)?

Yes, isolating platform-specific code with #ifdefs is the conventional way this is done.

Another approach would be to have a have clean #ifdef-less header which contains function declarations and put the implementations in platform specific source files.

For example, check out how POCO (Portable Components) C++ library does something similar for their Environment class.

jQuery.validator.methods.matches = function( value, element, params ) {
    var re = new RegExp(params);
    // window.console.log(re);
    // window.console.log(value);
    // window.console.log(re.test( value ));
    return this.optional( element ) || re.test( value );
}

rules: {
        input_telf: {
            required  : true,
            matches   : "^(\\d|\\s)+$",
            minlength : 10,
            maxlength : 20
        }
    }

Don't use quotes with <<EOF:

var=$1
sudo tee "/path/to/outfile" > /dev/null <<EOF
Some text that contains my $var
EOF

Variable expansion is the default behavior inside of here-docs. You disable that behavior by quoting the label (with single or double quotes).

A connection timeout occurs only upon starting the TCP connection. This usually happens if the remote machine does not answer. This means that the server has been shut down, you used the wrong IP/DNS name, wrong port or the network connection to the server is down.

A socket timeout is dedicated to monitor the continuous incoming data flow. If the data flow is interrupted for the specified timeout the connection is regarded as stalled/broken. Of course this only works with connections where data is received all the time.

By setting socket timeout to 1 this would require that every millisecond new data is received (assuming that you read the data block wise and the block is large enough)!

If only the incoming stream stalls for more than a millisecond you are running into a timeout.

Try connecting without any password:

mysql -u root

I believe the initial default is no password for the root account (which should obviously be changed as soon as possible).

Packages are just .xar archives with a different extension and a specified file hierarchy. Unfortunately, part of that file hierarchy is a cpio.gz archive of the actual installables, and usually that's what you want to edit. And there's also a Bom file that includes information on the files inside that cpio archive, and a PackageInfo file that includes summary information.

If you really do just need to edit one of the info files, that's simple:

mkdir Foo
cd Foo
xar -xf ../Foo.pkg
# edit stuff
xar -cf ../Foo-new.pkg *

But if you need to edit the installable files:

mkdir Foo
cd Foo
xar -xf ../Foo.pkg
cd foo.pkg
cat Payload | gunzip -dc |cpio -i
# edit Foo.app/*
rm Payload
find ./Foo.app | cpio -o | gzip -c > Payload
mkbom Foo.app Bom # or edit Bom
# edit PackageInfo
rm -rf Foo.app
cd ..
xar -cf ../Foo-new.pkg

I believe you can get mkbom (and lsbom) for most linux distros. (If you can get ditto, that makes things even easier, but I'm not sure if that's nearly as ubiquitously available.)

$ pip install django-better-choices

For those who are interested, I have created django-better-choices library, that provides a nice interface to work with Django choices for Python 3.7+. It supports custom parameters, lots of useful features and is very IDE friendly.

You can define your choices as a class:

from django_better_choices import Choices


class PAGE_STATUS(Choices):
    CREATED = 'Created'
    PENDING = Choices.Value('Pending', help_text='This set status to pending')
    ON_HOLD = Choices.Value('On Hold', value='custom_on_hold')

    VALID = Choices.Subset('CREATED', 'ON_HOLD')

    class INTERNAL_STATUS(Choices):
        REVIEW = 'On Review'

    @classmethod
    def get_help_text(cls):
        return tuple(
            value.help_text
            for value in cls.values()
            if hasattr(value, 'help_text')
        )

Then do the following operations and much much more:

print( PAGE_STATUS.CREATED )                # 'created'
print( PAGE_STATUS.ON_HOLD )                # 'custom_on_hold'
print( PAGE_STATUS.PENDING.display )        # 'Pending'
print( PAGE_STATUS.PENDING.help_text )      # 'This set status to pending'

'custom_on_hold' in PAGE_STATUS.VALID       # True
PAGE_STATUS.CREATED in PAGE_STATUS.VALID    # True

PAGE_STATUS.extract('CREATED', 'ON_HOLD')   # ~= PAGE_STATUS.VALID

for value, display in PAGE_STATUS:
    print( value, display )

PAGE_STATUS.get_help_text()
PAGE_STATUS.VALID.get_help_text()

And of course, it is fully supported by Django and Django Migrations:

class Page(models.Model):
    status = models.CharField(choices=PAGE_STATUS, default=PAGE_STATUS.CREATED)

Full documentation here: https://pypi.org/project/django-better-choices/

I faced a similar kind of issue while using a custom object as a key in Treemap. Whenever you are using a custom object as a key in hashmap then you override two function equals and hashcode, However if you are using ContainsKey method of Treemap on this object then you need to override CompareTo method as well otherwise you will be getting this error Someone using a custom object as a key in hashmap in kotlin should do like following

 data class CustomObjectKey(var key1:String = "" , var 
 key2:String = ""):Comparable<CustomObjectKey?>
 {
override fun compareTo(other: CustomObjectKey?): Int {
    if(other == null)
        return -1
   // suppose you want to do comparison based on key 1 
    return this.key1.compareTo((other)key1)
}

override fun equals(other: Any?): Boolean {
    if(other == null)
        return false
    return this.key1 == (other as CustomObjectKey).key1
}

override fun hashCode(): Int {
    return this.key1.hashCode()
} 
}

An elegant and short alternative, is the String.prototype.slice method.

Just by:

str.slice(-1);

A negative start index slices the string from length+index, to length, being index -1, the last character is extracted:

"abc".slice(-1); // "c";

Download the .whl file from this link.

The name of the file is: wxPython-3.0.2.0-cp27-none-win32.whl for Windows 32 bit and python 2.7 and wxPython-3.0.2.0-cp27-none-win_amd64.whl for Windows 64 bit and python 2.7.

Then in the command prompt: pip install location-of-the-above-saved-file

in a Visual Basic Macro you would use

pName = ActiveWorkbook.Path      ' the path of the currently active file
wbName = ActiveWorkbook.Name     ' the file name of the currently active file
shtName = ActiveSheet.Name       ' the name of the currently selected worksheet

The first sheet in a workbook can be referenced by

ActiveWorkbook.Worksheets(1)

so after deleting the [Report] tab you would use

ActiveWorkbook.Worksheets("Report").Delete
shtName = ActiveWorkbook.Worksheets(1).Name

to "work on that sheet later on" you can create a range object like

Dim MySheet as Range
MySheet = ActiveWorkbook.Worksheets(shtName).[A1]

and continue working on MySheet(rowNum, colNum) etc. ...

shortcut creation of a range object without defining shtName:

Dim MySheet as Range
MySheet = ActiveWorkbook.Worksheets(1).[A1]

In addition to the answers here...

if you are using jquery on the client side, this worked for me:

Java:

@RequestMapping(value = "/ajax/search/sync") 
public String sync(@RequestBody Foo json) {

Jquery (you need to include Douglas Crockford's json2.js to have the JSON.stringify function):

$.ajax({
    type: "post",
    url: "sync", //your valid url
    contentType: "application/json", //this is required for spring 3 - ajax to work (at least for me)
    data: JSON.stringify(jsonobject), //json object or array of json objects
    success: function(result) {
        //do nothing
    },
    error: function(){
        alert('failure');
    }
});

Your rows object holds an Item attribute where you can find the values for each of your columns. You can not expect the columns to concatenate themselves when you do a .ToString() on the row. You should access each column from the row separately, use a for or a foreach to walk the array of columns.

Here, take a look at the class:

http://msdn.microsoft.com/en-us/library/system.data.datarow.aspx

Try this

SELECT distinct id
FROM  (SELECT id, ROW_NUMBER() OVER (ORDER BY  id) AS RowNum
      FROM table
      WHERE fid = 64) t

Or use RANK() instead of row number and select records DISTINCT rank

SELECT id
FROM  (SELECT id, ROW_NUMBER() OVER (PARTITION BY  id ORDER BY  id) AS RowNum
      FROM table
      WHERE fid = 64) t
WHERE t.RowNum=1

This also returns the distinct ids

Use the isin method:

rpt[rpt['STK_ID'].isin(stk_list)]

I tested now 4h but it dont work 2021 with the group-chat-id. All the time the error {"ok":true,"result":[]}

But now i found a Solution:

1:) install the "Plus Messenger" (https://play.google.com/store/apps/details?id=org.telegram.plus)

2:) go in the Group => Tap now on the "Group-Name" in the Head => Double Tap now on the Headline from the Group. A Info is comming: ID123456789 is copy in the clipboard

3:) go in the Group an paste the clipboard text. It´s you Groud-ID

4:) looks like 1068773197, which is -1001068773197 for bots (with -100 prefix)!!!

Try using Math.abs:

variableAbs = Math.abs(variable);

For square root use:

variableSqRt = Math.sqrt(variable);

You use class media.FaceDetector in android to detect face for free.

This is an example of face detection: https://github.com/betri28/FaceDetectCamera

You can also keep adding strings to an existing string like so:

var myString = "Hello ";
myString += "World";
myString += "!";

the result would be -> Hello World!

Start your script with the following line. The script will first run and then you will get the python command prompt. At this point all variables and functions will be available for interactive use and invocations.

SQL tables are not ordered by default, and asking for the n-th row from a non ordered set of rows has no meaning as it could potentially return a different row each time unless you specify an ORDER BY:

select * from customer order by id where row_number() = 3

(sometimes MySQL tables are shown with an internal order but you cannot rely on this behaviour). Then you can use LIMIT offset, row_count, with a 0-based offset so row number 3 becomes offset 2:

select * from customer order by id
limit 2, 1

or you can use LIMIT row_count OFFSET offset:

select * from customer order by id
limit 1 offset 2

No need to care of whether before/after this digit having other type of words

To just match the pattern of 5 digits number anywhere in the string, no matter it is separated by space or not, use this regular expression (?<!\d)\d{5}(?!\d).

Sample JavaScript codes:

var regexp = new RegExp(/(?<!\d)\d{5}(?!\d)/g); 
    var matches = yourstring.match(regexp);
    if (matches && matches.length > 0) {
        for (var i = 0, len = matches.length; i < len; i++) {
            // ... ydo something with matches[i] ...
        } 
    }

Here's some quick results.

• abc12345xyz (?)

• 12345abcd (?)

• abcd12345 (?)

• 0000aaaa2 (?)

• a1234a5 (?)

• 12345 (?)

• <space>12345<space>12345 (??)

I have just ran into the same problem after updating. The JRE that is downloaded by OSX Lion is missing JavaRuntimeSupport.jar which will work but can wreck havoc on a lot of things. If you've updated, and you had a working JDK/JRE installed prior to that, do the following in Eclipse:

1) Project > Properties > Java Build Path > Select broken JRE/JDK > Edit

2) Select "Alternate JRE"

3) Click "Installed JREs..."

4) In the window that opens, click "Search..."

If all goes well, it will find your older JRE/JDK. Mine was in this location:

/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home

As you can see, the AND operator drops every row in which at least one value equals -1. On the other hand, the OR operator requires both values to be equal to -1 to drop them.

That's right. Remember that you're writing the condition in terms of what you want to keep, not in terms of what you want to drop. For df1:

df1 = df[(df.a != -1) & (df.b != -1)]

You're saying "keep the rows in which df.a isn't -1 and df.b isn't -1", which is the same as dropping every row in which at least one value is -1.

For df2:

df2 = df[(df.a != -1) | (df.b != -1)]

You're saying "keep the rows in which either df.a or df.b is not -1", which is the same as dropping rows where both values are -1.

PS: chained access like df['a'][1] = -1 can get you into trouble. It's better to get into the habit of using .loc and .iloc.

I am asking in general, how to write a compatible awk script that performs the same functionality ...

To solve the problem in your quesiton is easy. (check others' answer).

If you want to write an awk script, which portable to any awk implementations and versions (gawk/nawk/mawk...) it is really hard, even if with --posix (gawk)

for example:

• some awk works on string in terms of characters, some with bytes
• some supports \x escape, some not
• FS interpreter works differently
• keywords/reserved words abbreviation restriction
• some operator restriction e.g. **
• even same awk impl. (gawk for example), the version 4.0 and 3.x have difference too.
• the implementation of certain functions are also different. (your problem is one example, see below)

well all the points above are just spoken in general. Back to your problem, you problem is only related to fundamental feature of awk. awk '{print $x}' the line like that will work all awks.

There are two reasons why your awk line behaves differently on gawk and mawk:

• your used substr() function wrongly. this is the main cause. you have substr($0, 0, RSTART - 1) the 0 should be 1, no matter which awk do you use. awk array, string idx etc are 1-based.

• gawk and mawk implemented substr() differently.

As everyone mentioned, it might not be a good idea for layout purposes. I arrived to this question because I was wondering the same and I only wanted to know if it would be valid code.

Since it's valid, you can use it for other purposes. For example, what I'm going to use it for is to put some fancy "CSSed" divs inside table rows and then use a quick jQuery function to allow the user to sort the information by price, name, etc. This way, the only layout table will give me is the "vertical order", but I'll control width, height, background, etc of the divs by CSS.

You did not register your nib as below:

tableView.registerNib(UINib(nibName: "CustomCell", bundle: nil), forCellReuseIdentifier: "CustomCell")

configfiles = glob.glob('C:/Users/sam/Desktop/**/*.txt")

Doesn't works for all cases, instead use glob2

configfiles = glob2.glob('C:/Users/sam/Desktop/**/*.txt")

When you declare a variable, you need to declare its type - in this case: int. Also you've put a random comma in the while loop. It probably worth looking up the syntax for Java and consider using a IDE that picks up on these kind of mistakes. You probably want something like this:

int [] numbers = { 1, 2, 3, 4, 5 ,6, 7, 8, 9 , 10 };
int sum = 0;
for(int i = 0; i < numbers.length; i++){
    sum += numbers[i];
}
System.out.println("The sum is: " + sum);

EDIT: A more generic way of doing this that doesn't rely on the layout type (other than that it is a layout type which supports margins):

public static void setMargins (View v, int l, int t, int r, int b) {
    if (v.getLayoutParams() instanceof ViewGroup.MarginLayoutParams) {
        ViewGroup.MarginLayoutParams p = (ViewGroup.MarginLayoutParams) v.getLayoutParams();
        p.setMargins(l, t, r, b);
        v.requestLayout();
    }
}

You should check the docs for TextView. Basically, you'll want to get the TextView's LayoutParams object, and modify the margins, then set it back to the TextView. Assuming it's in a LinearLayout, try something like this:

TextView tv = (TextView)findViewById(R.id.my_text_view);
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams)tv.getLayoutParams();
params.setMargins(0, 0, 10, 0); //substitute parameters for left, top, right, bottom
tv.setLayoutParams(params);

I can't test it right now, so my casting may be off by a bit, but the LayoutParams are what need to be modified to change the margin.

NOTE

Don't forget that if your TextView is inside, for example, a RelativeLayout, one should use RelativeLayout.LayoutParams instead of LinearLayout.LayoutParams

Neither. You should separate content and presentation, giving your HTML code logical codes. Think of it this way; to a blind person, or on a browser that cannot display colors, what is left of your code? Why do you want it to be red?

Most probably, your decision to make text red is because you want to give it emphasis. So your HTML code should be:

<em>test</em>

This way, even non-visual browsers can make sure they give the text emphasis in one way or another.

Next step is to make the text red. But you don't want to add the color code everywhere, much more efficient to just add it once:

<style>
  em { color: red; }
</style>

This way, all emphasized code on your website becomes red, making it more constant.

This has been answered for the most part, but I will expand...

Step 1

My goal was to enable zoom at certain times, and disable it at others.

// enable pinch zoom
var $viewport = $('head meta[name="viewport"]');    
$viewport.attr('content', 'width=device-width, initial-scale=1, maximum-scale=4');

// ...later...

// disable pinch zoom
$viewport.attr('content', 'width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no');

Step 2

The viewport tag would update, but pinch zoom was still active!! I had to find a way to get the page to pick up the changes...

It's a hack solution, but toggling the opacity of body did the trick. I'm sure there are other ways to accomplish this, but here's what worked for me.

// after updating viewport tag, force the page to pick up changes           
document.body.style.opacity = .9999;
setTimeout(function(){
    document.body.style.opacity = 1;
}, 1);

Step 3

My problem was mostly solved at this point, but not quite. I needed to know the current zoom level of the page so I could resize some elements to fit on the page (think of map markers).

// check zoom level during user interaction, or on animation frame
var currentZoom = $document.width() / window.innerWidth;

I hope this helps somebody. I spent several hours banging my mouse before finding a solution.

In my case I was using Jade and I was using HTTP repository URL. Changing the Url to HTTPS worked for me.

Other ways in jQuery

var foo = $("#foo");
foo.children().remove();
//or
$("*", foo ).remove();
//or
foo.html("");
//or
foo.empty();

<select id='bookcategory' class="form-control" required="">
                    <option value="" disabled="disabled">Category</option>
                    <option value="1">LITERATURE & FICTION</option>
                    <option value="2">NON FICTION</option>
                    <option value="3">ACADEMIC</option>
            <option value="4">CHILDREN & TEENS</option>

                </select>

HTML form validation can be performed automatically by the browser. Try the above code:
The rest all will be done automatically, no need to create any js functions just this dropdown and a submit button.

Just for the sake of completeness you can just take the wanted data type and add brackets with the number of elements like so:

x <- character(10)

The webfonts link works now, in all browsers!

Simply add your themes to the font link separated by a pipe (|), like this

<link href="https://fonts.googleapis.com/icon?family=Material+Icons|Material+Icons+Outlined" rel="stylesheet">

Then reference the class, like this:

// class="material-icons" or class="material-icons-outlined"

<i class="material-icons">account_balance</i>
<i class="material-icons-outlined">account_balance</i>

This pattern will also work with Angular Material:

<mat-icon>account_balance</mat-icon>
<mat-icon class="material-icons-outlined">account_balance</mat-icon>

This happens in the following scenario: When working on Windows, the IDE is more than likely configured to edit files in Cp1252, which is a Microsoft adaptation of latin-11. The developer checks in, and the Continuous Integration server (usually running on Linux, which nowadays is all utf8) picks up the file, and tries to compile as a UTF-8 file, hence the warning.

Try changing the encoding to cp1252. This works. To avoid future problems of this kind, use the same encoding on all the developer machines.

Good luck...

Bash oneliner for multiple ignores:

svn propset svn:ignore ".project"$'\n'".settings"$'\n'".buildpath" "yourpath"

Yes, just open the "Source" Tab in the dev-tools and navigate to the script you want to change . Make your adjustments directly in the dev tools window and then hit ctrl+s to save the script - know the new js will be used until you refresh the whole page.

The best solution is to create a new branch with --orphan option as shown below

git checkout --orphan <branch name>

By this you will be able to create a new branch and directly checkout to the new branch. It will be a parentless branch.

By default the --orphan option doesn't remove the files in the working directory, so you can delete the working directory files by this:

git rm --cached -r

In details what the --orphan does:

--orphan <new_branch>
Create a new orphan branch, named <new_branch>, started from <start_point> and switch to it. The first commit made on this new branch will have no parents and it will be the root of a new history totally disconnected from all the other branches and commits.

The index and the working tree are adjusted as if you had previously run git checkout <start_point>. This allows you to start a new history that records a set of paths similar to <start_point> by easily running git commit -a to make the root commit.

This can be useful when you want to publish the tree from a commit without exposing its full history. You might want to do this to publish an open source branch of a project whose current tree is "clean", but whose full history contains proprietary or otherwise encumbered bits of code.

If you want to start a disconnected history that records a set of paths that is totally different from the one of <start_point>, then you should clear the index and the working tree right after creating the orphan branch by running git rm -rf . from the top level of the working tree. Afterwards you will be ready to prepare your new files, repopulating the working tree, by copying them from elsewhere, extracting a tarball, etc.

The disabled attribute's standard behavior only happens for form elements. Try unbinding the event:

$("span").unbind("click");

dietbuddha has a nice answer. In cases where you don't have a MINUS or EXCEPT, one option is to do a union all between the tables, group by with all the columns and make sure there is two of everything:

SELECT col1, col2, col3
FROM
(SELECT * FROM tableA
UNION ALL  
SELECT * FROM tableB) data
GROUP BY col1, col2, col3
HAVING count(*)!=2

Pickle save:

try:
    import cPickle as pickle
except ImportError:  # Python 3.x
    import pickle

with open('data.p', 'wb') as fp:
    pickle.dump(data, fp, protocol=pickle.HIGHEST_PROTOCOL)

See the pickle module documentation for additional information regarding the protocol argument.

Pickle load:

with open('data.p', 'rb') as fp:
    data = pickle.load(fp)

JSON save:

import json

with open('data.json', 'w') as fp:
    json.dump(data, fp)

Supply extra arguments, like sort_keys or indent, to get a pretty result. The argument sort_keys will sort the keys alphabetically and indent will indent your data structure with indent=N spaces.

json.dump(data, fp, sort_keys=True, indent=4)

JSON load:

with open('data.json', 'r') as fp:
    data = json.load(fp)

df.info() function will give you result something like as below. If you are using read_csv method of Pandas without sep parameter or sep with ",".

raw_data = pd.read_csv("a1:\aa2/aaa3/data.csv")
raw_data.info()
<class 'pandas.core.frame.DataFrame'>
RangeIndex: 5144 entries, 0 to 5143
Columns: 145 entries, R_fighter to R_age

Here's a working distillation of the above techniques, equivalent to "curl --insecure":

HttpClient getInsecureHttpClient() throws GeneralSecurityException {
    TrustStrategy trustStrategy = new TrustStrategy() {
        @Override
        public boolean isTrusted(X509Certificate[] chain, String authType) {
            return true;
        }
    };

    HostnameVerifier hostnameVerifier = new HostnameVerifier() {
        @Override
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    };

    return HttpClients.custom()
            .setSSLSocketFactory(new SSLConnectionSocketFactory(
                    new SSLContextBuilder().loadTrustMaterial(trustStrategy).build(),
                    hostnameVerifier))
            .build();
}

Use these lines in the code, because the textEntryView is the parent of username edittext and password edittext.

    final EditText input1 = (EditText) textEntryView .findViewById(R.id.username); 
    final EditText input2 = (EditText) textEntryView .findViewById(R.id.password); 

I needed to detect IE vs most everything else and I didn't want to depend on the UA string. I found that using es6number with Modernizr did exactly what I wanted. I don't have much concern with this changing as I don't expect IE to ever support ES6 Number. So now I know the difference between any version of IE vs Edge/Chrome/Firefox/Opera/Safari.

More details here: http://caniuse.com/#feat=es6-number

Note that I'm not really concerned about Opera Mini false negatives. You might be.

You can use PowerShell job cmdlets to achieve your goals.

There are 6 job related cmdlets available in PowerShell.

• Get-Job
  • Gets Windows PowerShell background jobs that are running in the current session
• Receive-Job
  • Gets the results of the Windows PowerShell background jobs in the current session
• Remove-Job
  • Deletes a Windows PowerShell background job
• Start-Job
  • Starts a Windows PowerShell background job
• Stop-Job
  • Stops a Windows PowerShell background job
• Wait-Job
  • Suppresses the command prompt until one or all of the Windows PowerShell background jobs running in the session are complete

You could do it like this.

jsFiddle

JS

var select = document.getElementById('mySelect');
select.onchange = function () {
    select.className = this.options[this.selectedIndex].className;
}

CSS

.redText {
    background-color:#F00;
}
.greenText {
    background-color:#0F0;
}
.blueText {
    background-color:#00F;
}

You could use option { background-color: #FFF; } if you want the list to be white.

HTML

<select id="mySelect" class="greenText">
    <option class="greenText" value="apple" >Apple</option>
    <option class="redText"   value="banana" >Banana</option>
    <option class="blueText" value="grape" >Grape</option>
</select>

Since this is a select it doesn't really make sense to use .yellowText as none selected if that's what you were getting at as something must be selected.

UPDATE January, 2017:

According to Can I use, the user-select is currently supported in all browsers except Internet Explorer 9 and earlier versions (but sadly still needs a vendor prefix).

All of the correct CSS variations are:

  -webkit-touch-callout: none; /* iOS Safari */_x000D_
    -webkit-user-select: none; /* Safari */_x000D_
     -khtml-user-select: none; /* Konqueror HTML */_x000D_
       -moz-user-select: none; /* Firefox */_x000D_
        -ms-user-select: none; /* Internet Explorer/Edge */_x000D_
            user-select: none; /* Non-prefixed version, currently_x000D_
                                  supported by Chrome and Opera */_x000D_
}

<p>_x000D_
  Selectable text._x000D_
</p>_x000D_
<p class="noselect">_x000D_
  Unselectable text._x000D_

Note that it's a non-standard feature (i.e. not a part of any specification). It is not guaranteed to work everywhere, and there might be differences in implementation among browsers and in the future browsers can drop support for it.

Similar as shown and mentioned:

Notes: Take into consideration that Cells will change their color (only) after the DataGridView Control is Visible. Therefore one practical solution would be using the:

VisibleChanged Event

In case you wish to keep your style when creating new Rows; also subscribe the:

RowsAdded Event

Example bellow:

///<summary> Instantiate the DataGridView Control. </summary>
private DataGridView dgView = new DataGridView;

///<summary> Method to configure DataGridView Control. </summary>
private void DataGridView_Configuration()
{
    // In this case the method just contains the VisibleChanged event subscription.

    dgView.VisibleChanged += DgView_VisibleChanged;

    // Uncomment line bellow in case you want to keep the style when creating new rows.
    // dgView.RowsAdded += DgView_RowsAdded;
}

///<summary> The actual Method that will re-design (Paint) DataGridView Cells. </summary>
 private void DataGridView_PaintCells()
 {
     int nrRows = dgView.Rows.Count;
     int nrColumns = dgView.Columns.Count;
     Color green = Color.LimeGreen;

     // Iterate over the total number of Rows
     for (int row = 0; row < nrRows; row++)
     {
         // Iterate over the total number of Columns
         for (int col = 0; col < nrColumns; col++) 
         {
             // Paint cell location (column, row)
             dgView[col, row].Style.BackColor = green;
         }
     }
 }

///<summary> The DataGridView VisibleChanged Event. </summary>
private void DataGridView_VisibleChanged(object sender, EventArgs e)
{
    DataGridView_PaintCells();
}

/// <summary> Occurrs when a new Row is Created. </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void DataGridView_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
{ 
    DataGridView_PaintCells(); 
}

Finally: Just call the DataGridView_Configuration() (method)
i.e: Form Load Event.

personaly, i'm using exceptions to handle validation. it requires following steps:

1. in your data binding expression, you need to add "ValidatesOnException=True"
2. in you data object you are binding to, you need to add DependencyPropertyChanged handler where you check if new value fulfills your conditions - if not - you restore to the object old value (if you need to) and you throw exception.
3. in your control template you use for displaying invalid value in the control, you can access Error collection and display exception message.

the trick here, is to bind only to objects which derive from DependencyObject. simple implementation of INotifyPropertyChanged wouldn't work - there is a bug in the framework, which prevents you from accessing error collection.

As serialization doesn't work generally (only when the order of properties matches: JSON.stringify({a:1,b:2}) !== JSON.stringify({b:2,a:1})) you have to check the count of properties and compare each property as well:

const objectsEqual = (o1, o2) =>_x000D_
    Object.keys(o1).length === Object.keys(o2).length _x000D_
        && Object.keys(o1).every(p => o1[p] === o2[p]);_x000D_
_x000D_
const obj1 = { name: 'John', age: 33};_x000D_
const obj2 = { age: 33, name: 'John' };_x000D_
const obj3 = { name: 'John', age: 45 };_x000D_
        _x000D_
console.log(objectsEqual(obj1, obj2)); // true_x000D_
console.log(objectsEqual(obj1, obj3)); // false

If you need a deep comparison, you can call the function recursively:

const obj1 = { name: 'John', age: 33, info: { married: true, hobbies: ['sport', 'art'] } };_x000D_
const obj2 = { age: 33, name: 'John', info: { hobbies: ['sport', 'art'], married: true } };_x000D_
const obj3 = { name: 'John', age: 33 };_x000D_
_x000D_
const objectsEqual = (o1, o2) => _x000D_
    typeof o1 === 'object' && Object.keys(o1).length > 0 _x000D_
        ? Object.keys(o1).length === Object.keys(o2).length _x000D_
            && Object.keys(o1).every(p => objectsEqual(o1[p], o2[p]))_x000D_
        : o1 === o2;_x000D_
        _x000D_
console.log(objectsEqual(obj1, obj2)); // true_x000D_
console.log(objectsEqual(obj1, obj3)); // false

Then it's easy to use this function to compare objects in arrays:

const arr1 = [obj1, obj1];
const arr2 = [obj1, obj2];
const arr3 = [obj1, obj3];

const arraysEqual = (a1, a2) => 
   a1.length === a2.length && a1.every((o, idx) => objectsEqual(o, a2[idx]));

console.log(arraysEqual(arr1, arr2)); // true
console.log(arraysEqual(arr1, arr3)); // false

Swift 4 answer based on helpful answer from @mbm29414.

Unfortunately, it requires the use of a XIB file. There doesn't appear to be an alternative.

The key parts are using a sizing cell (created only once) and registering the XIB when initializing the collection view.

Then you size each cell dynamically within the sizeForItemAt function.

// UICollectionView Vars and Constants
let CellXIBName = YouViewCell.XIBName
let CellReuseID = YouViewCell.ReuseID
var sizingCell = YouViewCell()


fileprivate func initCollectionView() {
    // Connect to view controller
    collectionView.dataSource = self
    collectionView.delegate = self

    // Register XIB
    collectionView.register(UINib(nibName: CellXIBName, bundle: nil), forCellWithReuseIdentifier: CellReuseID)

    // Create sizing cell for dynamically sizing cells
    sizingCell = Bundle.main.loadNibNamed(CellXIBName, owner: self, options: nil)?.first as! YourViewCell

    // Set scroll direction
    let layout = UICollectionViewFlowLayout()
    layout.scrollDirection = .vertical
    collectionView.collectionViewLayout = layout

    // Set properties
    collectionView.alwaysBounceVertical = true
    collectionView.alwaysBounceHorizontal = false

    // Set top/bottom padding
    collectionView.contentInset = UIEdgeInsets(top: collectionViewTopPadding, left: collectionViewSidePadding, bottom: collectionViewBottomPadding, right: collectionViewSidePadding)

    // Hide scrollers
    collectionView.showsVerticalScrollIndicator = false
    collectionView.showsHorizontalScrollIndicator = false
}

For Bootstrap 3 the default radio/button-group structure is :

<div class="btn-group" data-toggle="buttons">
    <label class="btn btn-primary">
        <input type="radio" name="options" id="option1"> Option 1
    </label>
    <label class="btn btn-primary">
        <input type="radio" name="options" id="option2"> Option 2
    </label>
    <label class="btn btn-primary">
        <input type="radio" name="options" id="option3"> Option 3
    </label>
</div>

And you can select the active one like this:

$('.btn-primary').on('click', function(){
    alert($(this).find('input').attr('id'));
}); 

I would suggest you using my method to get a resource ID. It's Much more efficient, than using getIdentidier() method, which is slow.

Here's the code:

/**
 * @author Lonkly
 * @param variableName - name of drawable, e.g R.drawable.<b>image</b>
 * @param ? - class of resource, e.g R.drawable.class or R.raw.class
 * @return integer id of resource
 */
public static int getResId(String variableName, Class<?> ?) {

    Field field = null;
    int resId = 0;
    try {
        field = ?.getField(variableName);
        try {
            resId = field.getInt(null);
        } catch (Exception e) {
            e.printStackTrace();
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return resId;

}

Using the sudo command for window users gives you the following suggestions:

First, install the scoop package management tool and execute the following commands:

Then use scoop to install the sudo command:

Finally, you can execute the command with sudo:

Try putting this HTML snippet into your served document:

<img id="ItemPreview" src="">

Then, on JavaScript side, you can dynamically modify image's src attribute with so-called Data URL.

document.getElementById("ItemPreview").src = "data:image/png;base64," + yourByteArrayAsBase64;

Alternatively, using jQuery:

$('#ItemPreview').attr('src', `data:image/png;base64,${yourByteArrayAsBase64}`);

This assumes that your image is stored in PNG format, which is quite popular. If you use some other image format (e.g. JPEG), modify the MIME type ("image/..." part) in the URL accordingly.

This issue might be helpful for you, it explains how to achieve TPUStrategy, a popular functionality of tf.contrib in TF<2.0.

So, in TF 1.X you could do the following:

resolver = tf.contrib.cluster_resolver.TPUClusterResolver('grpc://' + os.environ['COLAB_TPU_ADDR'])
tf.contrib.distribute.initialize_tpu_system(resolver)
strategy = tf.contrib.distribute.TPUStrategy(resolver)

And in TF>2.0, where tf.contrib is deprecated, you achieve the same by:

tf.config.experimental_connect_to_host('grpc://' + os.environ['COLAB_TPU_ADDR'])
resolver = tf.distribute.cluster_resolver.TPUClusterResolver('grpc://' + os.environ['COLAB_TPU_ADDR'])
tf.tpu.experimental.initialize_tpu_system(resolver)
strategy = tf.distribute.experimental.TPUStrategy(resolver)

   where TOne : BaseOne
   where TTwo : BaseTwo

In my case when i tried

$ hive --service metastore 

I got

MetaException(message:Version information not found in metastore. )

The necessary tables required for the metastore are missing in MySQL. Manually create the tables and restart hive metastore.

cd $HIVE_HOME/scripts/metastore/upgrade/mysql/ 

< Login into MySQL > 

mysql> drop database IF EXISTS <metastore db name>; 
mysql> create database <metastore db name>; 
mysql> use <metastore db name>; 
mysql> source hive-schema-2.x.x.mysql.sql; 

metastore db name should match the database name mentioned in hive-site.xml files connection property tag.

hive-schema-2.x.x.mysql.sql file depends on the version available in the current directory. Try to go for the latest because it holds many old schema files also.

Now try to execute hive --service metastore If everything goes cool, then simply start the hive from terminal.

>hive

I hope the above answer serves your need.

You can try this it'll convert the date format to DD-MM-YYYY:

df['DOB'] = pd.to_datetime(df['DOB'], dayfirst = True)

if you want to change your icons to a Vector , create a new one. and then in your Activity.java :

Toolbar toolbar = findViewById(R.id.your_toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
toolbar.setNavigationIcon(R.drawable.your_icon);
mToolbar.setOverflowIcon(ContextCompat.getDrawable(this, R.drawable.your_icon2));

To change Vector icon Color, go to your Vector XML file.. in this case it will be your_icon.xml, it will look like this :

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportWidth="24.0"
    android:viewportHeight="24.0">
<path
    android:fillColor="@color/Your_Color"
    android:pathData="M15.41,7.41L14,6l-6,6 6,6 1.41,-1.41L10.83,12z"/>

Note that we used these attributes to set the Vector's color :

android:fillColor="@color/Your_Color"

Edit : You can't use a color from your colors.XML or somewhere else , the color must be decalred directly in the Vector's XML file.. so it will look like this :

android:fillColor="#FFF"

You don't need to copy things around, webpack works different than gulp. Webpack is a module bundler and everything you reference in your files will be included. You just need to specify a loader for that.

So if you write:

var myImage = require("./static/myImage.jpg");

Webpack will first try to parse the referenced file as JavaScript (because that's the default). Of course, that will fail. That's why you need to specify a loader for that file type. The file- or url-loader for instance take the referenced file, put it into webpack's output folder (which should be build in your case) and return the hashed url for that file.

var myImage = require("./static/myImage.jpg");
console.log(myImage); // '/build/12as7f9asfasgasg.jpg'

Usually loaders are applied via the webpack config:

// webpack.config.js

module.exports = {
    ...
    module: {
        loaders: [
            { test: /\.(jpe?g|gif|png|svg|woff|ttf|wav|mp3)$/, loader: "file" }
        ]
    }
};

Of course you need to install the file-loader first to make this work.

Python does not add the current directory to sys.path, but rather the directory that the script is in. Add /home/bodacydo/work/project to either sys.path or $PYTHONPATH.

The issue here is that JSON, as a format, is generally parsed in full and then handled in-memory, which for such a large amount of data is clearly problematic.

The solution to this is to work with the data as a stream - reading part of the file, working with it, and then repeating.

The best option appears to be using something like ijson - a module that will work with JSON as a stream, rather than as a block file.

Edit: Also worth a look - kashif's comment about json-streamer and Henrik Heino's comment about bigjson.

I know it has been quite sometime that you asked this but, if someone else needs, I did what was saying here " How to upload a project to Github " and after the top answer of this question right here. And after was the top answer was saying here "git error: failed to push some refs to" I don't know what exactly made everything work. But now is working.

Maybe your dept_name columns have different charsets.

You could try to alter one or both of them:

ALTER TABLE department MODIFY dept_name VARCHAR(20) CHARACTER SET utf8;
ALTER TABLE course MODIFY dept_name VARCHAR(20) CHARACTER SET utf8;

cd /driveName driveName:\pathNamw

I wanted to see all the indices for the colnames because I needed to do a complicated column rearrangement, so I printed the colnames as a dataframe. The rownames are the indices.

as.data.frame(colnames(df))

1 A
2 B
3 C

One important step after you update your node is to link your node binary to the latest installed node version

sudo ln -sf /usr/local/n/versions/node/6.0.0/bin/node /usr/bin/node  

1 - Treat functions as objects.

2 - The apply method is similar to __call __ in Python, which allows you to use an instance of a given class as a function.

I just discovered Telerik has some great components, including Grid, and they are open source too. http://demos.telerik.com/aspnet-mvc/

Try out cat and sprintf in your for loop.

eg.

cat(sprintf("\"%f\" \"%f\"\n", df$r, df$interest))

See here

In Ubuntu, set path of node_modules in .bashrc file

export PATH="/home/username/node_modules/.bin:$PATH"

java -cp CLASSPATH is necesssary if you wish to specify all code in the classpath. This is useful for debugging code.

The jarred executable format: java -jar JarFile can be used if you wish to start the app with a single short command. You can specify additional dependent jar files in your MANIFEST using space separated jars in a Class-Path entry, e.g.:

Class-Path: mysql.jar infobus.jar acme/beans.jar

Both are comparable in terms of performance.

1.Use git reflog to get all references update.

2.git reset <id_of_commit_to_which_you_want_restore>

You can see the information regarding the transfer by doing:

curl_setopt($curl_exect, CURLINFO_HEADER_OUT, true);

before the request, and

$information = curl_getinfo($curl_exect);

after the request

View: http://www.php.net/manual/en/function.curl-getinfo.php

You can also use the CURLOPT_HEADER in your curl_setopt

curl_setopt($curl_exect, CURLOPT_HEADER, true);

$httpcode = curl_getinfo($c, CURLINFO_HTTP_CODE);

return $httpcode == 200;

These are just some methods of using the headers.

function leapYear(year)
{
  return ((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0);
}

The shortest:

command || exit /b

If you need, you can set the exit code:

command || exit /b 666

And you can also log:

command || echo ERROR && exit /b

I was searching for something similar and came accross something called the Singleton Pattern.

Reference: Singleton Pattern

I am working on a BulkLoader class to load different types of files and wanted to use the Singleton pattern for it. This way I can load files from my main application class and retrieve the loaded files easily from other classes.

Below is a simple example how you can make a score manager for a game with TypeScript and the Singleton pattern.

class SingletonClass {

private static _instance:SingletonClass = new SingletonClass();

private _score:number = 0;

constructor() {
    if(SingletonClass._instance){
        throw new Error("Error: Instantiation failed: Use SingletonDemo.getInstance() instead of new.");
    }
    SingletonClass._instance = this;
}

public static getInstance():SingletonClass
{
    return SingletonClass._instance;
}

public setScore(value:number):void
{
    this._score = value;
}

public getScore():number
{
    return this._score;
}

public addPoints(value:number):void
{
    this._score += value;
}

public removePoints(value:number):void
{
    this._score -= value;
}   }

Then anywhere in your other classes you would get access to the Singleton by:

var scoreManager = SingletonClass.getInstance();
scoreManager.setScore(10); scoreManager.addPoints(1);
scoreManager.removePoints(2); console.log( scoreManager.getScore() );

Use the ALLOW_PAGE_LOCKS clause of ALTER/CREATE INDEX:

ALTER INDEX indexname ON tablename SET (ALLOW_PAGE_LOCKS = OFF);

If you want to analyze, repair and optimize all tables in all databases in your MySQL server, you can do this in one go from the command line. You will need root to do that though.

mysqlcheck -u root -p --auto-repair --optimize --all-databases

Once you run that, you will be prompted to enter your MySQL root password. After that, it will start and you will see results as it's happening.

Example output:

yourdbname1.yourdbtable1       OK
yourdbname2.yourdbtable2       Table is already up to date
yourdbname3.yourdbtable3
note     : Table does not support optimize, doing recreate + analyze instead
status   : OK

etc..
etc...

Repairing tables
yourdbname10.yourdbtable10
warning  : Number of rows changed from 121378 to 81562
status   : OK

If you don't know the root password and are using WHM, you can change it from within WHM by going to: Home > SQL Services > MySQL Root Password

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
tbx.Text = "found!";

If Controls.Find is not found "textBox1" => error. You must add code.

If(tbx != null)

Edit:

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
If(tbx != null)
   tbx.Text = "found!";

A better idea,

if you want to put the error message just beneath the text field, you can do like this

.row.spacer20top
  .col-sm-6.form-group
    = f.label :first_name, "*Your First Name:"
    = f.text_field :first_name, :required => true, class: "form-control"
    = f.error_message_for(:first_name)

What is error_message_for?

In my case problem was in css and html layout. Layout was something like html - body - root - ... html and body was overflow: hidden, and root was position: fixed, height: 100vh.

Whith this layout browser tabs on mobile doesnt hide. For solve this I delete overflow: hidden from html and body and delete position: fixed, height: 100vh from root.

You are providing a string representation of a dict to the DataFrame constructor, and not a dict itself. So this is the reason you get that error.

So if you want to use your code, you could do:

df = DataFrame(eval(data))

But better would be to not create the string in the first place, but directly putting it in a dict. Something roughly like:

data = []
for row in result_set:
    data.append({'value': row["tag_expression"], 'key': row["tag_name"]})

But probably even this is not needed, as depending on what is exactly in your result_set you could probably:

• provide this directly to a DataFrame: DataFrame(result_set)
• or use the pandas read_sql_query function to do this for you (see docs on this)

the command to get the effective push remote for the branch, e.g., master, is:

git config branch.master.pushRemote || git config remote.pushDefault || git config branch.master.remote

Here's why (from the "man git config" output):

branch.name.remote [...] tells git fetch and git push which remote to fetch from/push to [...] [for push] may be overridden with remote.pushDefault (for all branches) [and] for the current branch [..] further overridden by branch.name.pushRemote [...]

For some reason, "man git push" only tells about branch.name.remote (even though it has the least precedence of the three) + erroneously states that if it is not set, push defaults to origin - it does not, it's just that when you clone a repo, branch.name.remote is set to origin, but if you remove this setting, git push will fail, even though you still have the origin remote

You can use the filter and then for the filter function use a reduction of the filtering array which checks and returns true when it finds a match then invert on return (!). The filter function is called once per element in the array. You are not doing a comparison of any of the elements in the function in your post.

var a1 = [1, 2, 3, 4],_x000D_
  a2 = [2, 3];_x000D_
_x000D_
var filtered = a1.filter(function(x) {_x000D_
  return !a2.reduce(function(y, z) {_x000D_
    return x == y || x == z || y == true;_x000D_
  })_x000D_
});_x000D_
_x000D_
document.write(filtered);

You have two choices, either correct your markup so that it uses correct elements and utilizes the Bootstrap grid system:

@import url('http://getbootstrap.com/dist/css/bootstrap.css');

<div class="container">_x000D_
     <h1>About Me</h1>_x000D_
    <div class="row">_x000D_
        <div class="col-md-4">_x000D_
            <div class="imgAbt">_x000D_
                <img width="220" height="220" src="img/me.jpg" />_x000D_
            </div>_x000D_
        </div>_x000D_
        <div class="col-md-8">_x000D_
            <p>Lots of text here...With the four tiers of grids available you're bound to run into issues where, at certain breakpoints, your columns don't clear quite right as one is taller than the other. To fix that, use a combination of a .clearfix and o</p>_x000D_
        </div>_x000D_
    </div>_x000D_
</div>

Or, if you wish the text to closely wrap the image, change your markup to:

@import url('http://getbootstrap.com/dist/css/bootstrap.css');

<div class="container">_x000D_
    <h1>About Me</h1>_x000D_
    <div class="row">_x000D_
        <div class="col-md-12">_x000D_
            <img style='float:left;width:200px;height:200px; margin-right:10px;' src="img/me.jpg" />_x000D_
            <p>Lots of text here...With the four tiers of grids available you're bound to run into issues where, at certain breakpoints, your columns don't clear quite right as one is taller than the other. To fix that, use a combination of a .clearfix and o</p>_x000D_

The same issue i was facing couple of months back and that is because end of free google map usage effective from i think June 11, 2018. Google does not provide free google maps now. You need to have a valid API key and valid billing used, which may give you 200$ of free usage.

Refer link for more details: Google map pricing

Follow the process here to get your api key.

If you are upto using only maps with specific user, you can try other map tools.

$('a').removeAttr('href')

or

$('a').click(function(){ return false})

Just wanted to thank KM for his valuable solution. I implemented it myself to reduce the amount of lines in a shrinkdatabase request on SQLServer. Here is my SQL request if it can help anyone :

-- Declare the variable to be used
DECLARE @Query varchar (1000)
DECLARE @MyDBN varchar(11);
-- Initializing the @MyDBN variable (possible values : db1, db2, db3, ...)
SET @MyDBN = 'db1';
-- Creating the request to execute
SET @Query='use '+ @MyDBN +'; ALTER DATABASE '+ @MyDBN +' SET RECOVERY SIMPLE WITH NO_WAIT; DBCC SHRINKDATABASE ('+ @MyDBN +', 1, TRUNCATEONLY); ALTER DATABASE '+ @MyDBN +' SET RECOVERY FULL WITH NO_WAIT'
-- 
EXEC (@Query)

A method based on np.split:

df = pd.DataFrame({    'A':[2,4,6,8,10,2,4,6,8,10],
                       'B':[10,-10,0,20,-10,10,-10,0,20,-10],
                       'C':[4,12,8,0,0,4,12,8,0,0],
                      'D':[9,10,0,1,3,np.nan,np.nan,np.nan,np.nan,np.nan]})

listOfDfs = [df.loc[idx] for idx in np.split(df.index,5)]

A small function that uses a modulo could take care of cases where the split is not even (e.g. np.split(df.index,4) will throw an error).

(Yes, I am aware that the original question was somewhat more specific than this. However, this is supposed to answer the question in the title.)

Try :

This is fine :

@logos = @attachments.select { |attachment| attachment.file_type == 'logo' }
@images = @attachments.select { |attachment| attachment.file_type == 'image' }

but for performance wise you don't need to iterate @attachments twice :

@logos , @images = [], []
@attachments.each do |attachment|
  @logos << attachment if attachment.file_type == 'logo'
  @images << attachment if attachment.file_type == 'image'
end

indexOf is case sensitive. This is because it uses the equals method to compare the elements in the list. The same thing goes for contains and remove.

It is strange how much beauty varies for different people. I find the list comprehension much clearer than filter+lambda, but use whichever you find easier.

There are two things that may slow down your use of filter.

The first is the function call overhead: as soon as you use a Python function (whether created by def or lambda) it is likely that filter will be slower than the list comprehension. It almost certainly is not enough to matter, and you shouldn't think much about performance until you've timed your code and found it to be a bottleneck, but the difference will be there.

The other overhead that might apply is that the lambda is being forced to access a scoped variable (value). That is slower than accessing a local variable and in Python 2.x the list comprehension only accesses local variables. If you are using Python 3.x the list comprehension runs in a separate function so it will also be accessing value through a closure and this difference won't apply.

The other option to consider is to use a generator instead of a list comprehension:

def filterbyvalue(seq, value):
   for el in seq:
       if el.attribute==value: yield el

Then in your main code (which is where readability really matters) you've replaced both list comprehension and filter with a hopefully meaningful function name.

Try this code, I get working fine.

 webSettings.setSupportZoom(true);
 webSettings.setBuiltInZoomControls(true);
 webSettings.setDisplayZoomControls(false);

{"a":"\u00e1"} and {"a":"á"} are different ways to write the same JSON document; The JSON decoder will decode the unicode escape.

In php 5.4+, php's json_encode does have the JSON_UNESCAPED_UNICODE option for plain output. On older php versions, you can roll out your own JSON encoder that does not encode non-ASCII characters, or use Pear's JSON encoder and remove line 349 to 433.

git rebase -i master

you will get the editor vm open and msgs something like this

Pick 2994283490 commit msg1
f 7994283490 commit msg2
f 4654283490 commit msg3
f 5694283490 commit msg4
#Some message 
#
#some more

Here I have changed pick for all the other commits to "f" (Stands for fixup).

git push -f origin feature/feature-branch-name-xyz

this will fixup all the commits to one commit and will remove all the other commits . I did this and it helped me.

You can use two elements, one inside the other, and give the outer one overflow: hidden and a width equal to the inner element together with a bottom padding so that the shadow on all the other sides are "cut off"

#outer {
    width: 100px;
    overflow: hidden;
    padding-bottom: 10px;
}

#outer > div {
    width: 100px;
    height: 100px;
    background: orange;

    -moz-box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
    -webkit-box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
    box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
}

Alternatively, float the outer element to cause it to shrink to the size of the inner element. See: http://jsfiddle.net/QJPd5/1/

If You are working on Frontend Then Use:

$currentStore=Mage::app()->getStore(); 

If You have store id then use

$store=Mage::getmodel('core/store')->load($storeId);

Add the following values to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion
Add:
DWORD ForceLog set value to 1
DWORD LogFailures set value to 1
DWORD LogResourceBinds set value to 1
DWORD EnableLog set value to 1
String LogPath set value to folder for logs (e.g. C:\FusionLog\)

Make sure you include the backslash after the folder name and that the Folder exists.

You need to restart the program that you're running to force it to read those registry settings.

By the way, don't forget to turn off fusion logging when not needed.

You can also do this:

var x = new object[] {
    new { firstName = "john", lastName = "walter" },
    new { brand = "BMW" }
};

And if they are the same anonymous type (firstName and lastName), you won't need to cast as object.

var y = new [] {
    new { firstName = "john", lastName = "walter" },
    new { firstName = "jill", lastName = "white" }
};

This should do:

$chunk = "abc\tdef\tghi";

Here is a link to an article with more extensive examples.

You concrete problem is caused because you're mixing discouraged and old school scriptlets <% %> with its successor EL ${}. They do not share the same variable scope. The allFestivals is not available in scriptlet scope and the i is not available in EL scope.

You should install JSTL (<-- click the link for instructions) and declare it in top of JSP as follows:

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

and then iterate over the list as follows:

<c:forEach items="${allFestivals}" var="festival">
    <tr>      
        <td>${festival.festivalName}</td>
        <td>${festival.location}</td>
        <td>${festival.startDate}</td>
        <td>${festival.endDate}</td>
        <td>${festival.URL}</td>  
    </tr>
</c:forEach>

(beware of possible XSS attack holes, use <c:out> accordingly)

Don't forget to remove the <jsp:useBean> as it has no utter value here when you're using a servlet as model-and-view controller. It would only lead to confusion. See also our servlets wiki page. Further you would do yourself a favour to disable scriptlets by the following entry in web.xml so that you won't accidently use them:

<jsp-config>
    <jsp-property-group>
        <url-pattern>*.jsp</url-pattern>
        <scripting-invalid>true</scripting-invalid>
    </jsp-property-group>
</jsp-config>

If you are filtering by common date this will return it:

dfs = [df1, df2, df3]
checker = dfs[-1]
check = set(checker.loc[:, 0])

for df in dfs[:-1]:
    check = check.intersection(set(df.loc[:, 0]))

print(checker[checker.loc[:, 0].isin(check)])

Parentheses in function definition

Parentheses () are being used in function definition:

function_name () { command1 ; command2 ; }

That is the reason you have to escape parentheses even in command parameters:

$ echo (
bash: syntax error near unexpected token `newline'

$ echo \(
(

$ echo () { command echo The command echo was redefined. ; }
$ echo anything
The command echo was redefined.

Notice: This setting is not available for accounts with 2-Step Verification enabled, which mean you have to disable 2 factor authentication.

If you disable the 2-Step Verification:

• Open your Gmail account in browser
• Navigate to Less secure app access
• Make Allow less secure apps => On

My app was an ASP.Net3.5 app (using version 2 of the framework). When ASP.Net3.5 apps got created Visual Studio automatically added scriptResourceHandler to the web.config. Later versions of .Net put this into the machine.config. If you run your ASP.Net 3.5 app using the version 4 app pool (depending on install order this is the default app pool), you will get this error.

When I moved to using the version 2.0 app pool. The error went away. I then had to deal with the error when serving WCF .svc :

HTTP Error 404.17 - Not Found The requested content appears to be script and will not be served by the static file handler

After some investigation, it seems that I needed to register the WCF handler. using the following steps:

1. open Visual Studio Command Prompt (as administrator)
2. navigate to "C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation"
3. Run servicemodelreg -i

Try a custom propTypes :

 const  childrenPropTypeLogic = (props, propName, componentName) => {
          const prop = props[propName];
          return React.Children
                   .toArray(prop)
                   .find(child => child.type !== 'div') && new Error(`${componentName} only accepts "div" elements`);
 };


static propTypes = {

   children : childrenPropTypeLogic

}

If the image size is variable or the design is responsive, in addition to wrapping the text, you can set a min width for the paragraph to avoid it to become too narrow.
Give an invisible CSS pseudo-element with the desired minimum paragraph width. If there isn't enough space to fit this pseudo-element, then it will be pushed down underneath the image, taking the paragraph with it.

#container:before {
  content: ' ';
  display: table;
  width: 10em;    /* Min width required */
}
#floated{
    float: left;
    width: 150px;
    background: red;
}

GC.Collect();

Keep in mind, though, that the Garbage Collector might not always clean up what you expect...

I had similar problem. I r?n npm cache clear, closed android SDK manager(which was open before) and re-ran npm install -g cordova and that was enough to solve the problem.

Your JRE_HOME does not need to point to the "bin" directory. Just set it to C:\Program Files\Java\jre1.8.0_25

two nested for loops?

 for a in x:
     print "--------------"
     for b in a:
             print b

It would help if you gave an example of what you want to do with the lists

Just select first row from the table , for oracle : select * from <table name> where rownum = 1;

And if you're using Xamarin (monotouch) framework, simply call

SystemSound.Vibrate.PlayAlertSound()

You could also try nextBoolean()-Method

Here is an example: http://www.tutorialspoint.com/java/util/random_nextboolean.htm

I'm working with .NET 4.5 and couldn't get this working... I was using WPF Custom Control Library. This worked for me in the end...

If you are using prototype.js then you can do this:

transport_select.observe('change', function(){
  toggleSelect(transport_select_id)
})

This eliminate (as hope) the problem in cross-browsers

This works both with headless and non-headless, and will start the window with the specified size instead of setting it after:

from selenium.webdriver import Firefox, FirefoxOptions

opts = FirefoxOptions()
opts.add_argument("--width=2560")
opts.add_argument("--height=1440")

driver = Firefox(options=opts)

Try this function. I just wrote it and haven't had much of a chance to test it, but my preliminary tests are promising.

public static XmlDocument JsonToXml(string json)
{
    XmlNode newNode = null;
    XmlNode appendToNode = null;
    XmlDocument returnXmlDoc = new XmlDocument();
    returnXmlDoc.LoadXml("<Document />");
    XmlNode rootNode = returnXmlDoc.SelectSingleNode("Document");
    appendToNode = rootNode;

    string[] arrElementData;
    string[] arrElements = json.Split('\r');
    foreach (string element in arrElements)
    {
        string processElement = element.Replace("\r", "").Replace("\n", "").Replace("\t", "").Trim();
        if ((processElement.IndexOf("}") > -1 || processElement.IndexOf("]") > -1) && appendToNode != rootNode)

            newNode = returnXmlDoc.CreateElement(processElement);
            appendToNode.AppendChild(newNode);
            appendToNode = newNode;
        }
        else
        {

            {
                arrElementData = processElement.Replace(": \"", ":").Replace("\",", "").Replace("\"", "").Split(':');
                newNode = returnXmlDoc.CreateElement(arrElementData[0]);
                for (int i = 1; i < arrElementData.Length; i++)
                {
                    newNode.InnerText += arrElementData[i];
                }

                appendToNode.AppendChild(newNode);
            }
        }
    }

    return returnXmlDoc;
}

another simple solution is to use fs.readFile instead of using require you can save a text file contaning a json object, and create a interval on the server to reload this object.

pros:

• no need to use external libs
• relevant for production (reloading config file on change)
• easy to implement

cons:

• you can't reload a module - just a json containing key-value data

For completeness here is the HTML Helper for DropDownListFor that adds enabled parameter, when false select is disabled. It keeps html attributes defined in markup, or it enables usage of html attributes in markup, it posts select value to server and usage is very clean and simple.

Here is the code for helper:

public static MvcHtmlString DropDownListFor<TModel, TProperty>(this HtmlHelper<TModel> html, Expression<Func<TModel, TProperty>> expression, IEnumerable<SelectListItem> selectList, object htmlAttributes, bool enabled)
{
  if (enabled)
  {
    return SelectExtensions.DropDownListFor<TModel, TProperty>(html, expression, selectList, htmlAttributes);
  }

  var htmlAttributesAsDict = HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes);
  htmlAttributesAsDict.Add("disabled", "disabled");
  string selectClientId = html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldId(ExpressionHelper.GetExpressionText(expression));
  htmlAttributesAsDict.Add("id", selectClientId + "_disabled");

  var hiddenFieldMarkup = html.HiddenFor<TModel, TProperty>(expression);
  var selectMarkup = SelectExtensions.DropDownListFor<TModel, TProperty>(html, expression, selectList, htmlAttributesAsDict);
  return MvcHtmlString.Create(selectMarkup.ToString() + Environment.NewLine + hiddenFieldMarkup.ToString());
}

and usage, goal is to disable select if there is just one item in options, markup:

@Html.DropDownListFor(m => m.SomeValue, Model.SomeList, new { @class = "some-class" }, Model.SomeList > 1)

And there is one even more elegant HTML Helper example, no post support for now (pretty straight forward job, just use HAP and add hidden input as root element sibling and swap id's):

public static MvcHtmlString Disable(this MvcHtmlString previous, bool disabled, bool disableChildren = false)
{
  if (disabled)
  {
    var canBeDisabled = new HashSet<string> { "button", "command", "fieldset", "input", "keygen", "optgroup", "option", "select", "textarea" };
    var doc = new HtmlDocument();
    doc.LoadHtml(previous.ToString());
    var rootElements = doc.DocumentNode.Descendants().Where(
      hn => hn.NodeType == HtmlNodeType.Element && 
      canBeDisabled.Contains(hn.Name.ToLower()) && 
      (disableChildren || hn.ParentNode.NodeType == HtmlNodeType.Document));

    foreach (var element in rootElements)
    {
      element.SetAttributeValue("disabled", "");
    }
    string html = doc.DocumentNode.OuterHtml;
    return MvcHtmlString.Create(html);
  }
  return previous;
}

For example there is a model property bool AllInputsDisabled, when true all html inputs should be disabled:

@Html.TextBoxFor(m => m.Address, new { placeholder = "Enter address" }).Disable(Model.AllInputsDisabled)

@Html.DropDownListFor(m => m.DoYou, Model.YesNoList).Disable(Model.AllInputsDisabled)

I had used below commands to migrate all branches to the new repository.

~$ git clone --mirror <url_of_old_repo>
~$ cd <name_of_old_repo>
~$ git remote add new-origin <url_of_new_repo>
~$ git push new-origin master
~$ git push new-origin --mirror

NOTE: I had to use second last (i.e. push master first) command while cloning a repo from Atlassian Stash to AWS CodeCommit (blank repo). I am not sure the reason, but after pushing (git push new-origin --mirror) default branch was referring to some other branch than master.

Another option suggested in this blog post is setting the style of the image as style="display: block;"

Messa's answer only works if the server isn't bothering to check the content-type header. You'll need to specify a content-type header if you want it to really work. Here's Messa's answer modified to include a content-type header:

import json
import urllib2
data = json.dumps([1, 2, 3])
req = urllib2.Request(url, data, {'Content-Type': 'application/json'})
f = urllib2.urlopen(req)
response = f.read()
f.close()

cpp is the preprocessor.

Run cpp filename.c to output the preprocessed code, or better, redirect it to a file with cpp filename.c > filename.preprocessed.

I believe the problem occurs when targeting by ID, because Chosen will copy the ID from the original select onto it's newly created div, leaving you with 2 elements of the same (now not-unique) ID on the current page.

When targeting Chosen by ID, use a selector specific to the select:

$( 'select#yourID' ).on( 'change', function() {
    console.log( $( this ).val() );
} );

...instead of...

$( '#yourID' ).on( 'change', function() {
    console.log( $( this ).val() );
} );

This works because Chosen mirrors its selected items back to the original (now hidden) select element, even in multi-mode.

(It also continues to work with or without Chosen, say... if you decide to go a different direction in your application.)

Multi-dimension arrays are (n-1)-dimension matrices.

So int[,] square = new int[2,2] is square matrix 2x2, int[,,] cube = new int [3,3,3] is a cube - square matrix 3x3. Proportionality is not required.

Jagged arrays are just array of arrays - an array where each cell contains an array.

So MDA are proportional, JD may be not! Each cell can contains an array of arbitrary length!

To avoid many if-else structures, let JavaScript do the trick automatically:

<select name="name" id="name">
   <option value="a">a</option>
   <option value="b">b</option>
</select>

<script type="text/javascript">
  document.getElementById('name').value = "<?php echo $_GET['name'];?>";
</script>

<select name="location" id="location">
  <option value="x">x</option>
  <option value="y">y</option>
</select>

<script type="text/javascript">
  document.getElementById('location').value = "<?php echo $_GET['location'];?>";
</script>

Renee's answer is well explained. Addition to the answer with an example:

Node does a lot of things to your file and one of the important is WRAPPING your file. Inside nodejs source code "module.exports" is returned. Lets take a step back and understand the wrapper. Suppose you have

greet.js

var greet = function () {
   console.log('Hello World');
};

module.exports = greet;

the above code is wrapped as IIFE(Immediately Invoked Function Expression) inside nodejs source code as follows:

(function (exports, require, module, __filename, __dirname) { //add by node

      var greet = function () {
         console.log('Hello World');
      };

      module.exports = greet;

}).apply();                                                  //add by node

return module.exports;                                      //add by node

and the above function is invoked (.apply()) and returned module.exports. At this time module.exports and exports pointing to the same reference.

Now, imagine you re-write greet.js as

exports = function () {
   console.log('Hello World');
};
console.log(exports);
console.log(module.exports);

the output will be

[Function]
{}

the reason is : module.exports is an empty object. We did not set anything to module.exports rather we set exports = function()..... in new greet.js. So, module.exports is empty.

Technically exports and module.exports should point to same reference(thats correct!!). But we use "=" when assigning function().... to exports, which creates another object in the memory. So, module.exports and exports produce different results. When it comes to exports we can't override it.

Now, imagine you re-write (this is called Mutation) greet.js (referring to Renee answer) as

exports.a = function() {
    console.log("Hello");
}

console.log(exports);
console.log(module.exports);

the output will be

{ a: [Function] }
{ a: [Function] }

As you can see module.exports and exports are pointing to same reference which is a function. If you set a property on exports then it will be set on module.exports because in JS, objects are pass by reference.

Conclusion is always use module.exports to avoid confusion. Hope this helps. Happy coding :)

This answer is specific for WordPress:

$base_dir = trailingslashit( get_stylesheet_directory() );
$base_url = trailingslashit( get_stylesheet_directory_uri() );

$media_dir = $base_dir . 'yourfolder/images/';
$media_url = $hase_url . 'yourfolder/images/';

$image_paths = glob( $media_dir . '*.jpg' );
$image_names = array();
$image_urls = array();

foreach ( $image_paths as $image ) {
    $image_names[] = str_replace( $media_dir, '', $image );
    $image_urls[] = str_replace( $media_dir, $media_url, $image );
}

// --- You now have:

// $image_paths ... list of absolute file paths 
// e.g. /path/to/wordpress/wp-content/uploads/yourfolder/images/sample.jpg

// $image_urls ... list of absolute file URLs 
// e.g. http://example.com/wp-content/uploads/yourfolder/images/sample.jpg

// $image_names ... list of filenames only
// e.g. sample.jpg

Here are some other settings that will give you images from other places than the child theme. Just replace the first 2 lines in above code with the version you need:

From Uploads directory:

// e.g. /path/to/wordpress/wp-content/uploads/yourfolder/images/sample.jpg
$upload_path = wp_upload_dir();
$base_dir = trailingslashit( $upload_path['basedir'] );
$base_url = trailingslashit( $upload_path['baseurl'] );

From Parent-Theme

// e.g. /path/to/wordpress/wp-content/themes/parent-theme/yourfolder/images/sample.jpg
$base_dir = trailingslashit( get_template_directory() );
$base_url = trailingslashit( get_template_directory_uri() );

From Child-Theme

// e.g. /path/to/wordpress/wp-content/themes/child-theme/yourfolder/images/sample.jpg
$base_dir = trailingslashit( get_stylesheet_directory() );
$base_url = trailingslashit( get_stylesheet_directory_uri() );

After doing everything in the above answers, I figured out I was not running Visual Studio as Admin. After running as Admin, problem solved.

Would appreciate any thoughts on the situation with 3 data sets. Say a logistic regression model is fitted yielding the following accuracy (Gini): Train: 70%; Test 58% and Out-of-time validation: 66%.

Actually all the possible combinations of predictors bring the same results with quite a huge drop between train and test data sets. The sample size is around 8k divided into train and test 70/30. OOT sample contains a few thousands of cases. Regularization, ensembles didn't help in solving this.

I doubt whether this is something I should concern if OOT performance is acceptable and close to train sample performance?

See the defaultValue property of a text input, it's also used when you reset the form by clicking an <input type="reset"/> button (http://www.w3schools.com/jsref/prop_text_defaultvalue.asp )

btw, defaultValue and placeholder text are different concepts, you need to see which one better fits your needs

Additional information about removing/uninstalling composer

Answers above did not help me, but what did help me is removing:

1. ~/.cache/composer
2. ~/.local/share/composer
3. ~/.config/composer

Hope this helps.

you will have date column which was set to lesathan the min value of allowed dattime like 1/1/1001.

to overcome this issue you can set the proper datetime value to ur property adn also set another magical property like IsSpecified=true.

There is no binding for exactly what you want.

The only thing that comes close is Ctrl+F2 which will select all of them at once.

You can bind it to Ctrl+D doing the following:

• Click on File > Preferences > Keyboard Shortcuts
  You should see a pane full of the current bindings and on the right a list of custom bindings
• In the current bindings, search for Ctrl+F2 and copy that whole line and paste it into the right pane.
• You might have to remove the comma at the end and then change Ctrl+F2 to Ctrl+D and then save the file.

It should look something like this:

// Place your key bindings in this file to overwrite the defaults
[
{ "key": "ctrl+d",               "command": "editor.action.changeAll",
                                    "when": "editorTextFocus" }
]

dplyr package could be nice alternative to this problem:

library(dplyr)

df %>% 
  group_by(group) %>% 
  summarize(mean = mean(dt),
            sum = sum(dt))

To get 1st quadrant and 3rd quadrant

df %>% 
  group_by(group) %>% 
  summarize(q1 = quantile(dt, 0.25),
            q3 = quantile(dt, 0.75))

I am afraid the body of your question is unrelated to title question.

If to answer the title:

In SQL, is UPDATE always faster than DELETE+INSERT?

then answer is NO!

Just google for

• "Expensive direct update"* "sql server"
• "deferred update"* "sql server"

Such update(s) result in more costly (more processing) realization of update through insert+update than direct insert+update. These are the cases when

• one updates the field with unique (or primary) key or
• when the new data does not fit (is bigger) in the pre-update row space allocated (or even maximum row size),resulting in fragmentation,
• etc.

My fast (non-exhaustive) search, not pretending to be covering one, gave me [1], [2]

I'm using XML to carry the result back from the php on the server to the webpage and I have had the same behaviour.

In my case the reason was , that the closing tag did not match the opening tag.
