Just listen to what the warning is telling you:

Reshape your data either X.reshape(-1, 1) if your data has a single feature/column and X.reshape(1, -1) if it contains a single sample.

For your example type(if you have more than one feature/column):

temp = temp.reshape(1,-1) 

For one feature/column:

temp = temp.reshape(-1,1)

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt


def butter_lowpass(cutoff, fs, order=5):
    nyq = 0.5 * fs
    normal_cutoff = cutoff / nyq
    b, a = butter(order, normal_cutoff, btype='low', analog=False)
    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()

(Tested for pandas 1.0.5)
Based on @athlonshi answer (it had ValueError: could not convert string to float: 'big', on C column), full working example without warning:

import pandas as pd
from sklearn.preprocessing import MinMaxScaler
scale = preprocessing.MinMaxScaler()

df = pd.DataFrame({
           'A':[14.00,90.20,90.95,96.27,91.21],
           'B':[103.02,107.26,110.35,114.23,114.68], 
           'C':['big','small','big','small','small']
         })
print(df)
df[["A","B"]] = pd.DataFrame(scale.fit_transform(df[["A","B"]].values), columns=["A","B"], index=df.index)
print(df)

       A       B      C
0  14.00  103.02    big
1  90.20  107.26  small
2  90.95  110.35    big
3  96.27  114.23  small
4  91.21  114.68  small
          A         B      C
0  0.000000  0.000000    big
1  0.926219  0.363636  small
2  0.935335  0.628645    big
3  1.000000  0.961407  small
4  0.938495  1.000000  small

To set the range of the x-axis, you can use set_xlim(left, right), here are the docs

Update:

It looks like you want an identical plot, but only change the 'tick values', you can do that by getting the tick values and then just changing them to whatever you want. So for your need it would be like this:

ticks = your_plot.get_xticks()*10**9
your_plot.set_xticklabels(ticks)

If you can change the signature of your function to async Task then you can use the code presented here

int average_in_int = ( (Double) Math.ceil( sum/count ) ).intValue();

If you're looking to store the current time just use MYSQL's functions.

mysql_query("INSERT INTO `table` (`dateposted`) VALUES (now())");

If you need to use PHP to do it, the format it Y-m-d H:i:s so try

$date = date('Y-m-d H:i:s');
mysql_query("INSERT INTO `table` (`dateposted`) VALUES ('$date')");

Here is how you can check if the token exists:

if (jobject["Result"].SelectToken("Items") != null) { ... }

It checks if "Items" exists in "Result".

This is a NOT working example that causes exception:

if (jobject["Result"]["Items"] != null) { ... }

See ?merge:

the name "row.names" or the number 0 specifies the row names.

Example:

R> de <- merge(d, e, by=0, all=TRUE)  # merge by row names (by=0 or by="row.names")
R> de[is.na(de)] <- 0                 # replace NA values
R> de
  Row.names   a   b   c   d   e   f   g   h   i  j  k  l  m  n  o  p  q  r  s

I always use Gliffy works perfectly and does lots of things including class diagrams.

Give headercss position fixed.

.headercss {
    width: 100%;
    height: 320px;
    background-color: #000000;
    position: fixed;
    top:0
}

Then give the content container a 320px padding-top, so it doesn't get behind the header.

Update 2016:

Google Chrome released the storage API: http://developer.chrome.com/extensions/storage.html

It is pretty easy to use like the other Chrome APIs and you can use it from any page context within Chrome.

    // Save it using the Chrome extension storage API.
    chrome.storage.sync.set({'foo': 'hello', 'bar': 'hi'}, function() {
      console.log('Settings saved');
    });

    // Read it using the storage API
    chrome.storage.sync.get(['foo', 'bar'], function(items) {
      message('Settings retrieved', items);
    });

To use it, make sure you define it in the manifest:

    "permissions": [
      "storage"
    ],

There are methods to "remove", "clear", "getBytesInUse", and an event listener to listen for changed storage "onChanged"

Using native localStorage (old reply from 2011)

Content scripts run in the context of webpages, not extension pages. Therefore, if you're accessing localStorage from your contentscript, it will be the storage from that webpage, not the extension page storage.

Now, to let your content script to read your extension storage (where you set them from your options page), you need to use extension message passing.

The first thing you do is tell your content script to send a request to your extension to fetch some data, and that data can be your extension localStorage:

contentscript.js

chrome.runtime.sendMessage({method: "getStatus"}, function(response) {
  console.log(response.status);
});

background.js

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
    if (request.method == "getStatus")
      sendResponse({status: localStorage['status']});
    else
      sendResponse({}); // snub them.
});

You can do an API around that to get generic localStorage data to your content script, or perhaps, get the whole localStorage array.

I hope that helped solve your problem.

To be fancy and generic ...

contentscript.js

chrome.runtime.sendMessage({method: "getLocalStorage", key: "status"}, function(response) {
  console.log(response.data);
});

background.js

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
    if (request.method == "getLocalStorage")
      sendResponse({data: localStorage[request.key]});
    else
      sendResponse({}); // snub them.
});

The order of execution of ng-click and ng-model is ambiguous since they do not define clear priorities. Instead you should use ng-change or a $watch on the $scope to ensure that you obtain the correct values of the model variable.

In your case, this should work:

<input type="checkbox" ng-model="vm.myChkModel" ng-change="vm.myClick(vm.myChkModel)">

If you already have your parameters set like $_POST['eg'] for example and you don't wish to change it, simply do it like this:

$_POST = json_decode(file_get_contents('php://input'), true);

This will save you the hassle of changing all $_POST to something else and allow you to still make normal post requests if you wish to take this line out.

For me, IIS Express was not accessible when I added iplisten on DOS Prompt like this: netsh http add iplisten MyIPAddress. I fixed it by deleting the iplisten like this: netsh http delete iplisten MyIPAddress.

Sub TestSave()
Application.Quit
ThisWorkBook.Close SaveChanges = False
End Sub

This seems to work for me, Even though looks like am quitting app before saving, but it saves...

Solution posted by Denys S. in the question post:

I quite messed it up with c to c++ conversion (basically env variable stuff), but I got it working with the following code for C++:

#include <string.h>
#include <stdio.h>
#include <jni.h>

jstring Java_the_package_MainActivity_getJniString( JNIEnv* env, jobject obj){

    jstring jstr = (*env)->NewStringUTF(env, "This comes from jni.");
    jclass clazz = (*env)->FindClass(env, "com/inceptix/android/t3d/MainActivity");
    jmethodID messageMe = (*env)->GetMethodID(env, clazz, "messageMe", "(Ljava/lang/String;)Ljava/lang/String;");
    jobject result = (*env)->CallObjectMethod(env, obj, messageMe, jstr);

    const char* str = (*env)->GetStringUTFChars(env,(jstring) result, NULL); // should be released but what a heck, it's a tutorial :)
    printf("%s\n", str);

    return (*env)->NewStringUTF(env, str);
}

And next code for java methods:

    public class MainActivity extends Activity {
    private static String LIB_NAME = "thelib";

    static {
        System.loadLibrary(LIB_NAME);
    }

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TextView tv = (TextView) findViewById(R.id.textview);
        tv.setText(this.getJniString());
    }

    // please, let me live even though I used this dark programming technique
    public String messageMe(String text) {
        System.out.println(text);
        return text;
    }

    public native String getJniString();
}

I know this thread has been idle for a while, but I just wanted to add my two cents to supplement jariq's comment...

Per manual, you don't necessary want to use -password option.

Let's say mykey.key has a password and your want to protect iphone-dev.p12 with another password, this is what you'd use:

pkcs12 -export -inkey mykey.key -in developer_identity.pem -out iphone_dev.p12 -passin pass:password_for_mykey -passout pass:password_for_iphone_dev

Have fun scripting!!

Without the need to install the grep variant pcregrep, you can do multiline search with grep.

$ grep -Pzo "(?s)^(\s*)\N*main.*?{.*?^\1}" *.c

Explanation:

-P activate perl-regexp for grep (a powerful extension of regular expressions)

-z suppress newline at the end of line, substituting it for null character. That is, grep knows where end of line is, but sees the input as one big line.

-o print only matching. Because we're using -z, the whole file is like a single big line, so if there is a match, the entire file would be printed; this way it won't do that.

In regexp:

(?s) activate PCRE_DOTALL, which means that . finds any character or newline

\N find anything except newline, even with PCRE_DOTALL activated

.*? find . in non-greedy mode, that is, stops as soon as possible.

^ find start of line

\1 backreference to the first group (\s*). This is a try to find the same indentation of method.

As you can imagine, this search prints the main method in a C (*.c) source file.

The word "read" is vague, but here is an example which reads a jpeg file using the Image class, and prints information about it.

from PIL import Image
jpgfile = Image.open("picture.jpg")

print(jpgfile.bits, jpgfile.size, jpgfile.format)

I was trying to do a similar task to get a dropdown arrow always on the right side of the table header and came up with this which seemed to work in Chrome and Firefox, but safari was telling me it was an invalid property.

background: url(http://goo.gl/P93P5Q) center right 10px no-repeat;

After doing a bit of messing around in the inspector, I came up with this cross-browser solution that works in IE8+, Chrome, Firefox, and Safari, as well as responsive designs.

background: url(http://goo.gl/P93P5Q) no-repeat 95% center;

Here is a codepen of how it looks and works. Codepen is written with SCSS - http://cdpn.io/xqGbk

This would change all the occurrences of those letters in all names:

 names(x) <- gsub("q", "A", gsub("e", "B", names(x) ) )

Sorry for resurrection. You could use child_process module to execute external js files in node.js

var child_process = require('child_process');

//EXECUTE yourExternalJsFile.js
child_process.exec('node yourExternalJsFile.js', (error, stdout, stderr) => {
    console.log(`${stdout}`);
    console.log(`${stderr}`);
    if (error !== null) {
        console.log(`exec error: ${error}`);
    }
});

Javascript Email Validation in MVC/ASP.NET

The problem I came across while using Fabian's answer, is implementing it in an MVC view because of the Razor @ symbol. You have to include an additional @ symbol to escape it, like so: @@

To Avoid Razor In MVC

function isEmail(email) {
  var regex = /^([a-zA-Z0-9_.+-])+\@@(([a-zA-Z0-9-])+\.)+([a-zA-Z0-9]{2,4})+$/;
  return regex.test(email);
}

I didn't see it elsewhere on this page, so I thought it might be helpful.

EDIT

Here's a link from Microsoft describing it's usage.
I just tested the code above and got the following js:

function validateEmail(email) {
  var regex = /^([a-zA-Z0-9_.+-])+\@(([a-zA-Z0-9-])+\.)+([a-zA-Z0-9]{2,4})+$/; 
  return regex.test(email);
}

Which is doing exactly what it's supposed to do.

I disagree that .form-group should be within .col-*-n elements. In my experience, all the appropriate padding happens automatically when you use .form-group like .row within a form.

<div class="form-group">
    <div class="col-sm-12">
        <label for="user_login">Username</label>
        <input class="form-control" id="user_login" name="user[login]" required="true" size="30" type="text" />
    </div>
</div>

Check out this demo.

Altering the demo slightly by adding .form-horizontal to the form tag changes some of that padding.

<form action="#" method="post" class="form-horizontal">

Check out this demo.

When in doubt, inspect in Chrome or use Firebug in Firefox to figure out things like padding and margins. Using .row within the form fails in edsioufi's fiddle because .row uses negative left and right margins thereby drawing the horizontal bounds of the divs classed .row beyond the bounds of the containing fieldsets.

I've extended David Baucum's answer to include support for extensions up to 4 digits in length. It also includes the parentheses requested in the original question. This formatting will work as you type in the field.

phone = phone.replace(/\D/g, '');
const match = phone.match(/^(\d{1,3})(\d{0,3})(\d{0,4})(\d{0,4})$/);
if (match) {
    phone = `(${match[1]}${match[2] ? ') ' : ''}${match[2]}${match[3] ? '-' : ''}${match[3]}${match[4] ? ' x' : ''}${match[4]}`;
}
return phone;

The "vw" solution has a problem when going to very small screens. You can set the base size and go up from there with calc():

font-size: calc(16px + 0.4vw);

Here is code not using the percentage in the keyframes. Because you used percentages the animation does nothing a long time.

• 0% translate 0px
• 20% translate 0px
• etc.

How does this example work:

1. We set an animation. This is a short hand for animation properties.
2. We immediately start the animation since we use from and to in the keyframes. from is = 0% and to is = 100%
3. We can now control how fast it will bounce by setting the animation time: animation: bounce 1s infinite alternate; the 1s is how long the animation will last.

.ball {_x000D_
  margin-top: 50px;_x000D_
  border-radius: 50%;_x000D_
  width: 50px;_x000D_
  height: 50px;_x000D_
  background-color: cornflowerblue;_x000D_

I agree with the chosen answer to use DecimalFormat --- or alternatively BigDecimal.

Please read Update below first!

However if you do want to round the double value and get a double value result, you can use org.apache.commons.math3.util.Precision.round(..) as mentioned above. The implementation uses BigDecimal, is slow and creates garbage.

A similar but fast and garbage-free method is provided by the DoubleRounder utility in the decimal4j library:

 double a = DoubleRounder.round(2.0/3.0, 3);
 double b = DoubleRounder.round(2.0/3.0, 3, RoundingMode.DOWN);
 double c = DoubleRounder.round(1000.0d, 17);
 double d = DoubleRounder.round(90080070060.1d, 9);
 System.out.println(a);
 System.out.println(b);
 System.out.println(c);
 System.out.println(d);

Will output

 0.667
 0.666
 1000.0
 9.00800700601E10

See https://github.com/tools4j/decimal4j/wiki/DoubleRounder-Utility

Disclaimer: I am involved in the decimal4j project.

Update: As @iaforek pointed out DoubleRounder sometimes returns counterintuitive results. The reason is that it performs mathematically correct rounding. For instance DoubleRounder.round(256.025d, 2) will be rounded down to 256.02 because the double value represented as 256.025d is somewhat smaller than the rational value 256.025 and hence will be rounded down.

Notes:

• This behaviour is very similar to that of the BigDecimal(double) constructor (but not to valueOf(double) which uses the string constructor).
• The problem can be circumvented with a double rounding step to a higher precision first, but it is complicated and I am not going into the details here

For those reasons and everything mentioned above in this post I cannot recommend to use DoubleRounder.

FormatDateTime(Now, DateFormat.ShortDate)

In short, vmalloc and kmalloc both could fix fragmentation. vmalloc use memory mappings to fix external fragmentation; kmalloc use slab to fix internal frgamentation. Fot what it's worth, kmalloc also has many other advantages.

Also, consider to use a repository manager such as Nexus and configure all your repositories there.

Set the default password in the .pgpass file. If the server does not save the password, it is because it is not set in the .pgpass file, or the permissions are open and the file is therefore ignored.

Read more about the password file here.

Also, be sure to check the permissions: on *nix systems the permissions on .pgpass must disallow any access to world or group; achieve this by the command chmod 0600 ~/.pgpass. If the permissions are less strict than this, the file will be ignored.

Have you tried logging-in using PGAdmin? You can save the password there, and modify the pgpass file.

So my question is: Is there a way to tell the compiler that a long long int is the also a int64_t, just like long int is?

This is a good question or problem, but I suspect the answer is NO.

Also, a long int may not be a long long int.

# if __WORDSIZE == 64
typedef long int  int64_t;
# else
__extension__
typedef long long int  int64_t;
# endif

I believe this is libc. I suspect you want to go deeper.

In both 32-bit compile with GCC (and with 32- and 64-bit MSVC), the output of the program will be:

int:           0
int64_t:       1
long int:      0
long long int: 1

32-bit Linux uses the ILP32 data model. Integers, longs and pointers are 32-bit. The 64-bit type is a long long.

Microsoft documents the ranges at Data Type Ranges. The say the long long is equivalent to __int64.

However, the program resulting from a 64-bit GCC compile will output:

int:           0
int64_t:       1
long int:      1
long long int: 0

64-bit Linux uses the LP64 data model. Longs are 64-bit and long long are 64-bit. As with 32-bit, Microsoft documents the ranges at Data Type Ranges and long long is still __int64.

There's a ILP64 data model where everything is 64-bit. You have to do some extra work to get a definition for your word32 type. Also see papers like 64-Bit Programming Models: Why LP64?

But this is horribly hackish and does not scale well (actual functions of substance, uint64_t, etc)...

Yeah, it gets even better. GCC mixes and matches declarations that are supposed to take 64 bit types, so its easy to get into trouble even though you follow a particular data model. For example, the following causes a compile error and tells you to use -fpermissive:

#if __LP64__
typedef unsigned long word64;
#else
typedef unsigned long long word64;
#endif

// intel definition of rdrand64_step (http://software.intel.com/en-us/node/523864)
// extern int _rdrand64_step(unsigned __int64 *random_val);

// Try it:
word64 val;
int res = rdrand64_step(&val);

It results in:

error: invalid conversion from `word64* {aka long unsigned int*}' to `long long unsigned int*'

So, ignore LP64 and change it to:

typedef unsigned long long word64;

Then, wander over to a 64-bit ARM IoT gadget that defines LP64 and use NEON:

error: invalid conversion from `word64* {aka long long unsigned int*}' to `uint64_t*'

if you use mvvm and your itemssource is located in your vm. just call INotifyPropertyChanged for your collection property when you want to refresh.

OnPropertyChanged("YourCollectionProperty");

It is working for "greater than" functions not for less than.

For example:

select date_part('year',txndt)
from "table_name"
where date_part('year',txndt) > '2000' limit 10;

is working fine.

but for

select date_part('year',txndt)
from "table_name"
where date_part('year',txndt) < '2000' limit 10;

I am getting error.

you can find the third most salary with this query:

SELECT min(salary) 
FROM tblEmployee 
WHERE salary IN (SELECT TOP(3) salary 
                 FROM tblEmployee 
                 ORDER BY salary DESC)

The standard would be ALTER TABLE, but that's not necessarily supported by every DBMS you're likely to encounter, so if you're looking for an all-encompassing syntax, you may be out of luck.

Set environment variables and use headers to receive them:

You can create new environment variables with RewriteRule lines, as mentioned by OP:

RewriteRule ^(.*) - [E=TEST0:%{DOCUMENT_ROOT}/blog/html_cache/$1.html]

But if you can't get a server-side script to work, how can you then read this environment variable? One solution is to set a header:

Header set TEST_FOOBAR "%{REDIRECT_TEST0}e"

The value accepts format specifiers, including the %{NAME}e specifier for environment variables (don't forget the lowercase e). Sometimes, you'll need to add the REDIRECT_ prefix, but I haven't worked out when the prefix gets added and when it doesn't.

Not sure of the exact question but is this what you are looking for?

        prices.put("eggs", new Integer[] {1, 1, 2});
     }
}

Although the accepted answer here is technically correct, there seems to be some confusion amongst users based on the comments. When working with a ViewBag in a .cshtml file, you must use @Html.Raw otherwise your data, after being unescaped by the ConfigurationManager, will become re-escaped once again. Use Html.Raw() to prevent this from occurring.

db.example.updateMany({},{"$unset":{"tags.words":1}})

We can also use this to update multiple documents.

I had this problem with bundles having incorrect path's to images and CssRewriteUrlTransform not resolving relative parent paths .. correctly (there was also problem with external resources like webfonts). That's why I wrote this custom transform (appears to do all of the above correctly):

public class CssRewriteUrlTransform2 : IItemTransform
{
    public string Process(string includedVirtualPath, string input)
    {
        var pathParts = includedVirtualPath.Replace("~/", "/").Split('/');
        pathParts = pathParts.Take(pathParts.Count() - 1).ToArray();
        return Regex.Replace
        (
            input,
            @"(url\(['""]?)((?:\/??\.\.)*)(.*?)(['""]?\))",
            m => 
            {
                // Somehow assigning this to a variable is faster than directly returning the output
                var output =
                (
                    // Check if it's an aboslute url or base64
                    m.Groups[3].Value.IndexOf(':') == -1 ?
                    (
                        m.Groups[1].Value +
                        (
                            (
                                (
                                    m.Groups[2].Value.Length > 0 ||
                                    !m.Groups[3].Value.StartsWith('/')
                                )
                            ) ?
                            string.Join("/", pathParts.Take(pathParts.Count() - m.Groups[2].Value.Count(".."))) :
                            ""
                        ) +
                        (!m.Groups[3].Value.StartsWith('/') ? "/" + m.Groups[3].Value : m.Groups[3].Value) +
                        m.Groups[4].Value
                    ) :
                    m.Groups[0].Value
                );
                return output;
            }
        );
    }
}

Edit: I didn't realize it, but I used some custom extension methods in the code. The source code of those is:

/// <summary>
/// Based on: http://stackoverflow.com/a/11773674
/// </summary>
public static int Count(this string source, string substring)
{
    int count = 0, n = 0;

    while ((n = source.IndexOf(substring, n, StringComparison.InvariantCulture)) != -1)
    {
        n += substring.Length;
        ++count;
    }
    return count;
}

public static bool StartsWith(this string source, char value)
{
    if (source.Length == 0)
    {
        return false;
    }
    return source[0] == value;
}

Of course it should be possible to replace String.StartsWith(char) with String.StartsWith(string).

Like this:

{% if age > 18 %}
    {% with patient as p %}
    <my html here>
    {% endwith %}
{% else %}
    {% with patient.parent as p %}
    <my html here>
    {% endwith %}
{% endif %}

If the html is too big and you don't want to repeat it, then the logic would better be placed in the view. You set this variable and pass it to the template's context:

p = (age > 18 && patient) or patient.parent

and then just use {{ p }} in the template.

I tried below code to find duplicate values from list

1) create a set of duplicate list

2) Iterated through set by looking in duplicate list.

glist=[1, 2, 3, "one", 5, 6, 1, "one"]
x=set(glist)
dup=[]
for c in x:
    if(glist.count(c)>1):
        dup.append(c)
print(dup)

OUTPUT

[1, 'one']

Now get the all index for duplicate element

glist=[1, 2, 3, "one", 5, 6, 1, "one"]
x=set(glist)
dup=[]
for c in x:
    if(glist.count(c)>1):
        indices = [i for i, x in enumerate(glist) if x == c]
        dup.append((c,indices))
print(dup)

OUTPUT

[(1, [0, 6]), ('one', [3, 7])]

Hope this helps someone

For me (being on Windows 10) the npmrc file was located in:

%USERPROFILE%\.npmrc

Tested with:

• npm v4.2.0
• Node.js v7.8.0

Those answers aren't bad, but they are limited in that they don't actually allow you to enter data. We had a similar problem where we were using barcode readers to enter data into a field, but we wanted to suppress the keyboard.

This is what I put together, it works pretty well:

https://codepen.io/bobjase/pen/QrQQvd/

<!-- must be a select box with no children to suppress the keyboard -->
input: <select id="hiddenField" /> 
<span id="fakecursor" />

<input type="text" readonly="readonly" id="visibleField" />
<div id="cursorMeasuringDiv" />

#hiddenField {
  height:17px; 
  width:1px;
  position:absolute;
  margin-left:3px;
  margin-top:2px;
  border:none;
  border-width:0px 0px 0px 1px;
}

#cursorMeasuringDiv {
  position:absolute;
  visibility:hidden;
  margin:0px;
  padding:0px;
}

#hiddenField:focus {
  border:1px solid gray;  
  border-width:0px 0px 0px 1px;
  outline:none;
  animation-name: cursor;
  animation-duration: 1s;
  animation-iteration-count: infinite;
}

@keyframes cursor {
    from {opacity:0;}
    to {opacity:1;}
}

// whenever the visible field gets focused
$("#visibleField").bind("focus", function(e) {
  // silently shift the focus to the hidden select box
  $("#hiddenField").focus();
  $("#cursorMeasuringDiv").css("font", $("#visibleField").css("font"));
});

// whenever the user types on his keyboard in the select box
// which is natively supported for jumping to an <option>
$("#hiddenField").bind("keypress",function(e) {
  // get the current value of the readonly field
  var currentValue = $("#visibleField").val();

  // and append the key the user pressed into that field
  $("#visibleField").val(currentValue + e.key);
  $("#cursorMeasuringDiv").text(currentValue + e.key);

  // measure the width of the cursor offset
  var offset = 3;
  var textWidth = $("#cursorMeasuringDiv").width();
  $("#hiddenField").css("marginLeft",Math.min(offset+textWidth,$("#visibleField").width()));

});

When you click in the <input> box, it simulates a cursor in that box but really puts the focus on an empty <select> box. Select boxes naturally allow for keypresses to support jumping to an element in the list so it was only a matter of rerouting the keypress to the original input and offsetting the simulated cursor.

This won't work for backspace, delete, etc... but we didn't need those. You could probably use jQuery's trigger to send the keyboard event directly to another input box somewhere but we didn't need to bother with that so I didn't do it.

on this web http://quirksmode.org/css/css2/columns.html i found that easy way

<table>
<col style="background-color: #6374AB; color: #ffffff" />
<col span="2" style="background-color: #07B133; color: #ffffff;" />
<tr>..

You can't do it with just CSS, but you can do it with Javascript, and (optionally) jQuery.

If you want to do it without jQuery:

<script>
    window.onload = function() {
        var anchors = document.getElementsByTagName('a');
        for(var i = 0; i < anchors.length; i++) {
            var anchor = anchors[i];
            anchor.onclick = function() {
                alert('ho ho ho');
            }
        }
    }
</script>

And to do it without jQuery, and only on a specific class (ex: hohoho):

<script>
    window.onload = function() {
        var anchors = document.getElementsByTagName('a');
        for(var i = 0; i < anchors.length; i++) {
            var anchor = anchors[i];
            if(/\bhohoho\b/).match(anchor.className)) {
                anchor.onclick = function() {
                    alert('ho ho ho');
                }
            }
        }
    }
</script>

If you are okay with using jQuery, then you can do this for all anchors:

<script>
    $(document).ready(function() {
        $('a').click(function() {
            alert('ho ho ho');
        });
    });
</script>

And this jQuery snippet to only apply it to anchors with a specific class:

<script>
    $(document).ready(function() {
        $('a.hohoho').click(function() {
            alert('ho ho ho');
        });
    });
</script>

**multiple delete not working**

function delete_selection() 
{
        $id_array = array();
        $selection = $this->input->post("selection", TRUE);
        $id_array = explode("|", $selection);

        foreach ($id_array as $item):
            if ($item != ''):
                //DELETE ROW
                $this->db->where('entry_id', $item);
                $this->db->delete('helpline_entry');
            endif;
        endforeach;
    }

This is a slightly modified solution. The Process will be killed when it was idle for at least 1 second. Maybe you should add a timeof of X seconds and call the function from a separate thread.

private void SendToPrinter()
{
  ProcessStartInfo info = new ProcessStartInfo();
  info.Verb = "print";
  info.FileName = @"c:\output.pdf";
  info.CreateNoWindow = true;
  info.WindowStyle = ProcessWindowStyle.Hidden;

  Process p = new Process();
  p.StartInfo = info;
  p.Start();

  long ticks = -1;
  while (ticks != p.TotalProcessorTime.Ticks)
  {
    ticks = p.TotalProcessorTime.Ticks;
    Thread.Sleep(1000);
  }

  if (false == p.CloseMainWindow())
    p.Kill();
}

For this specific use-case using try..except..else is the cleanest solution, the else clause will be executed if no exception was raised.

NOTE: The else clause must follow all except clauses

for i in iterator:
    try:
        # Do something.
    except:
        # Handle exception
    else:
        # Continue doing something

Find this useful solution

function get_duplicates( $array ) {
    return array_unique( array_diff_assoc( $array, array_unique( $array ) ) );
}

After that count result if greater than 0 than duplicates else unique.

This is what you need to do.

I tried to recreate the situation...

• For this example, I created a .NET sample WebService (WS) with a WebMethod called Function1 expecting the following params:

Function1(Contact Contact, string description, int amount)

• Where Contact is just a model that has getters and setters for id and name like in your case.

• You can download the .NET sample WS at:

https://www.dropbox.com/s/6pz1w94a52o5xah/11593623.zip

The code.

This is what you need to do at PHP side:

(Tested and working)

<?php
// Create Contact class
class Contact {
    public function __construct($id, $name) 
    {
        $this->id = $id;
        $this->name = $name;
    }
}

// Initialize WS with the WSDL
$client = new SoapClient("http://localhost:10139/Service1.asmx?wsdl");

// Create Contact obj
$contact = new Contact(100, "John");

// Set request params
$params = array(
  "Contact" => $contact,
  "description" => "Barrel of Oil",
  "amount" => 500,
);

// Invoke WS method (Function1) with the request params 
$response = $client->__soapCall("Function1", array($params));

// Print WS response
var_dump($response);

?>

Testing the whole thing.

• If you do print_r($params) you will see the following output, as your WS would expect:

Array ( [Contact] => Contact Object ( [id] => 100 [name] => John ) [description] => Barrel of Oil [amount] => 500 )

• When I debugged the .NET sample WS I got the following:

(As you can see, Contact object is not null nor the other params. That means your request was successfully done from PHP side)

• The response from the .NET sample WS was the expected one and this is what I got at PHP side:

object(stdClass)[3] public 'Function1Result' => string 'Detailed information of your request! id: 100, name: John, description: Barrel of Oil, amount: 500' (length=98)

Happy Coding!

To check where the dump.rdb has to be placed when importing redis data,

start client

$redis-cli

and

then

redis 127.0.0.1:6379> CONFIG GET *
 1) "dir"
 2) "/Users/Admin"

Here /Users/Admin is the location of dump.rdb that is read from server and therefore this is the file that has to be replaced.

Handling polymorphism is either model-bound or requires lots of code with various custom deserializers. I'm a co-author of a JSON Dynamic Deserialization Library that allows for model-independent json deserialization library. The solution to OP's problem can be found below. Note that the rules are declared in a very brief manner.

        // create a deserializer instance
        DynamicObjectDeserializer deserializer = new DynamicObjectDeserializer();

        deserializer.addRule(DeserializationRuleFactory.newRule(1, 
                (e) -> e.getJsonNode().has("breed"),
                DeserializationActionFactory.objectToType(Dog.class)));

Renaming Columns (Laravel 5.x)

To rename a column, you may use the renameColumn method on the Schema builder. *Before renaming a column, be sure to add the doctrine/dbal dependency to your composer.json file.*

Or you can simply required the package using composer...

composer require doctrine/dbal

Source: https://laravel.com/docs/5.0/schema#renaming-columns

Note: Use make:migration and not migrate:make for Laravel 5.x

Got it. (updated/improved version)

The ECMAscript standard does not specify which sort algorithm is to be used. Indeed, different browsers feature different sort algorithms. For example, Mozilla/Firefox's sort() is not stable (in the sorting sense of the word) when sorting a map. IE's sort() is stable.

If you only need the date and not the time use:

select*from table where exec_datetime
between subdate(curdate(), 30)and curdate();

Since curdate() omits the time component, it's potentially faster than now() and more "semantically correct" in cases where you're only interested in the date.

Also, subdate()'s 2-arity overload is potentially faster than using interval. interval is meant to be for cases when you need a non-day component.

A printer doesn't understand pixels, it understand dots (pt in CSS). The best solution is to write an extra CSS for printing, with all of its measures in dots.

Then, in your HTML code, in head section, put:

<link href="style.css" rel="stylesheet" type="text/css" media="screen">
<link href="style_print.css" rel="stylesheet" type="text/css" media="print">

Write header file #include<process.h> and replace exit(); with exit(0);. This will definitely work in Turbo C; for other compilers I don't know.

As mentioned in previous answers, both serve almost same purpose. Personally I like git rebase and merge request (as in gitlab). It takes burden off of the reviewer/maintainer, making sure that while adding merge request, the feature branch includes all of the latest commits done on main branch after feature branch is created. Here is a very useful article explaining rebase in detail: https://git-scm.com/book/en/v2/Git-Branching-Rebasing

This worked for me:

curl -v --cookie "USER_TOKEN=Yes" http://127.0.0.1:5000/

I could see the value in backend using

print request.cookies

But in my opinion one important thing.

The "char(number)" it's lenght of variable.

If we've got table with "Names" like for example [Test1..Test200] and we declare char(5) in SELECT like:

DECLARE @variable char(5)
SET @variable = 'Test1%'
SELECT * FROM table WHERE Name like @variable

the result will be only - "Test1"! (char(5) - 5 chars in lenght; Test11 is 6 )

The rest of potential interested data like [Test11..Test200] will not be returned in the result.

It's ok if we want to limit the SELECT by this way. But if it's not intentional way of doing it could return incorrect results from planned ( Like "all Names begining with Test1..." ).

In my opinion if we don't know the precise lenght of a SELECTed value, a better solution could be something like this one:

DECLARE @variable varchar(max)
SET @variable = 'Test1%'
SELECT * FROM <table> WHERE variable1 like @variable

This returns (Test1 but also Test11..Test19 and Test100..Test199).

In my case I solved it by manually deleting a record in the SQLite ".svn\wc" file lock record in the WC_LOCK table.

I opened the "WC" file with SQLite editor and executed

delete from WC_LOCK

Following eakkas's comment, you might need to delete all the entries from WORK_QUEUE table as well.

If you guys are looking for a solution for Android, you can use the following code to get the epoch seconds from the timestamp string.

public static long timestampToEpochSeconds(String srcTimestamp) {
    long epoch = 0;

    try {
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            Instant instant = Instant.parse(srcTimestamp);
            epoch = instant.getEpochSecond();
        } else {
            SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSSSS'Z'", Locale.getDefault());
            sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
            Date date = sdf.parse(srcTimestamp);
            if (date != null) {
                epoch = date.getTime() / 1000;
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

    return epoch;
}

Sample input: 2019-10-15T05:51:31.537979Z

Sample output: 1571128673

This worked for me with span (knockout validation).

<span class="validationMessage">This field is required.</span>

.validationMessage {
    background-image: url('images/exclamation.png');
    background-repeat: no-repeat;
    margin-left: 5px;
    width: 16px;
    height: 16px;
    vertical-align: top;

    /* Hide the text. */
    display: inline-block;
    overflow: hidden;
    font-size: 0px;
}

Also, would I be right in concluding that a list comprehension is the most efficient way to do this?

Maybe. List comprehensions are not inherently computationally efficient. It is still running in linear time.

From my personal experience: I have significantly reduced computation time when dealing with large data sets by replacing list comprehensions (specifically nested ones) with for-loop/list-appending type structures you have above. In this application I doubt you will notice a difference.

BOOTSTRAP 4

you can use a combination of

• fa-chevron-down, fa-chevron-up

• fa-sort-down, fa-sort-up

<th class="text-center">
    <div class="btn-group" role="group">
        <button type="button" class="btn btn-xs btn-link py-0 pl-0 pr-1">
             Some Text OR icon
        </button>
        <div class="btn-group-vertical">
            <a href="?sort=asc" class="btn btn-xs btn-link p-0">
                <i class="fas fa-sort-up"></i>
            </a>
            <a href="?sort=desc" class="btn btn-xs btn-link p-0">
                <i class="fas fa-sort-down"></i>
            </a>
        </div>
    </div>

If you are using SQL 2005 you can do something like this...

SELECT rs.Field1,rs.Field2 
    FROM (
        SELECT Field1,Field2, Rank() 
          over (Partition BY Section
                ORDER BY RankCriteria DESC ) AS Rank
        FROM table
        ) rs WHERE Rank <= 10

If your RankCriteria has ties then you may return more than 10 rows and Matt's solution may be better for you.

A little mathematical logic theory here:

"NOT a AND NOT b" is the same as "NOT (a OR b)", so:

"a NOT -1 AND b NOT -1" is equivalent of "NOT (a is -1 OR b is -1)", which is opposite (Complement) of "(a is -1 OR b is -1)".

So if you want exact opposite result, df1 and df2 should be as below:

df1 = df[(df.a != -1) & (df.b != -1)]
df2 = df[(df.a == -1) | (df.b == -1)]

If anyone else comes across this and the accepted answer doesn't work (it didn't for me), check to see if you need to specify a port other than 80. In my case, I was running a rails server at localhost:3000 and was just using curl http://localhost, which was hitting port 80.

Changing the command to curl http://localhost:3000 is what worked in my case.

Just do:

sudo apt-get install python-lxml

For Python 2 (e.g., required by Inkscape):

sudo apt-get install python2-lxml

If you are planning to install from source, then albertov's answer will help. But unless there is a reason, don't, just install it from the repository.

To add and simplify Günter Zöchbauer's the example incase using (if...else) to set something else than background image :

<p [ngStyle]="value == 10 && { 'font-weight': 'bold' }">

=INDIRECT("'C:\Data["&A8&"]SheetNAME'!$G9")

where A8 contains myExcelFile.xlsm

and G9 contains your source workbook precious data.

Use this react native library

To install

npm install react-native-htmlview --save

Basic Usage

 import React from 'react';
 import HTMLView from 'react-native-htmlview';

  class App extends React.Component {
  render() {
   const htmlContent = 'This is a sentence <b>with</b> one word in bold';

  return (
   <HTMLView
     value={htmlContent}
   />    );
  }
}

Supports almost all html tags.

To find rows where col is NULL, empty string or whitespace (spaces, tabs):

SELECT *
FROM table
WHERE ISNULL(LTRIM(RTRIM(col)),'')=''

To find rows where col is NOT NULL, empty string or whitespace (spaces, tabs):

SELECT *
FROM table
WHERE ISNULL(LTRIM(RTRIM(col)),'')<>''

Sometimes you have to remove the current options in order to manipulate the selected options.

Here is an example how to set options:

<select id="mySelectId" class="chosen-select" multiple="multiple">
  <option value=""></option>
  <option value="Argentina">Argentina</option>
  <option value="Germany">Germany</option>
  <option value="Greece">Greece</option>
  <option value="Japan">Japan</option>
  <option value="Thailand">Thailand</option>
</select>

<script>
activateChosen($('body'));
selectChosenOptions($('#mySelectId'), ['Argentina', 'Germany']);

function activateChosen($container, param) {
    param = param || {};
    $container.find('.chosen-select:visible').chosen(param);
    $container.find('.chosen-select').trigger("chosen:updated");
}

function selectChosenOptions($select, values) {
    $select.val(null);                                  //delete current options
    $select.val(values);                                //add new options
    $select.trigger('chosen:updated');
}
</script>

I know this is a very old thread but I was looking for a solution to the same problem and I came across this before eventually finding the answer and I wanted to just post it here so somebody else in my shoes would have a shorter trek across the internet.

****Note that you probably have to run cmd.exe as an administrator for this to work**

So here we go, open up the prompt (as an adminstrator) and go to your System32 directory. Then run

C:\Windows\System32>cd ras

Now you'll be in the ras directory. Now it's time to create a temporary file with our connection info that we will then append onto the rasphone.pbk file that will allow us to use the rasdial command.

So to create our temp file run:

C:\Windows\System32\ras>copy con temp.txt

Now it will let you type the contents of the file, which should look like this:

[CONNECTION NAME]
MEDIA=rastapi
Port=VPN2-0
Device=WAN Miniport (IKEv2)
DEVICE=vpn
PhoneNumber=vpn.server.address.com

So replace CONNECTION NAME and vpn.server.address.com with the desired connection name and the vpn server address you want.

Make a new line and press Ctrl+Z to finish and save.

Now we will append this onto the rasphone.pbk file that may or may not exist depending on if you already have network connections configured or not. To do this we will run the following command:

C:\Windows\System32\ras>type temp.txt >> rasphone.pbk

This will append the contents of temp.txt to the end of rasphone.pbk, or if rasphone.pbk doesn't exist it will be created. Now we might as well delete our temp file:

C:\Windows\System32\ras>del temp.txt

Now we can connect to our newly configured VPN server with the following command:

C:\Windows\System32\ras>rasdial "CONNECTION NAME" myUsername myPassword

When we want to disconnect we can run:

C:\Windows\System32\ras>rasdial /DISCONNECT

That should cover it! I've included a direct copy and past from the command line of me setting up a connection for and connecting to a canadian vpn server with this method:

Microsoft Windows [Version 6.2.9200]
(c) 2012 Microsoft Corporation. All rights reserved.

Device=WAN Miniport (IKEv2)
DEVICE=vpn
PhoneNumber=ca.justfreevpn.com
^Z
        1 file(s) copied.

C:\Windows\System32\ras>type temp.txt >> rasphone.pbk

C:\Windows\System32\ras>del temp.txt

Hope this helps.

The following worked for me:

function changeOrientation(){
switch(window.orientation) {
case 0: // portrait, home bottom
case 180: // portrait, home top
 alert("portrait H: "+$(window).height()+" W: "+$(window).width());       
 break;
          case -90: // landscape, home left
          case 90: // landscape, home right
        alert("landscape H: "+$(window).height()+" W: "+$(window).width());
            break;
        }
    }

 window.onorientationchange = function() { 
            //Need at least 800 milliseconds
            setTimeout(changeOrientation, 1000);
        }

I needed the timeout because the value of window.orientation does not update right away

I'd rather not rely on swap() or setting the queue to a newly created queue object, because the queue elements are not properly destroyed. Calling pop()invokes the destructor for the respective element object. This might not be an issue in <int> queues but might very well have side effects on queues containing objects.

Therefore a loop with while(!queue.empty()) queue.pop();seems unfortunately to be the most efficient solution at least for queues containing objects if you want to prevent possible side effects.

For those that want it ISO 8601 compliant, since the other solutions do not have the T separator nor the time offset (except Meistro's answer):

from datetime import datetime, timezone
result = datetime.fromtimestamp(1463288494, timezone.utc).isoformat('T', 'microseconds')
print(result) # 2016-05-15T05:01:34.000000+00:00

Note, I use fromtimestamp because if I used utcfromtimestamp I would need to chain on .astimezone(...) anyway to get the offset.

If you don't want to go all the way to microseconds you can choose a different unit with the isoformat() method.

Something like that should be what you need

private void button1_Click(object sender, RoutedEventArgs e)
{
    // Create OpenFileDialog 
    Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();



    // Set filter for file extension and default file extension 
    dlg.DefaultExt = ".png";
    dlg.Filter = "JPEG Files (*.jpeg)|*.jpeg|PNG Files (*.png)|*.png|JPG Files (*.jpg)|*.jpg|GIF Files (*.gif)|*.gif"; 


    // Display OpenFileDialog by calling ShowDialog method 
    Nullable<bool> result = dlg.ShowDialog();


    // Get the selected file name and display in a TextBox 
    if (result == true)
    {
        // Open document 
        string filename = dlg.FileName;
        textBox1.Text = filename;
    }
}

You mention you are using OS X- I have used cronnix in the past. It's not as geeky as editing it yourself, but it helped me learn what the columns are in a jiffy. Just a thought.

Do

<script>//<![CDATA[
    /* script */
//]]></script>

You could also do this

#include <comdef.h>

BSTR bs = SysAllocString("Hello");
std::wstring myString = _bstr_t(bs, false); // will take over ownership, so no need to free

or std::string if you prefer

EDIT: if your original string contains multiple embedded \0 this approach will not work.

var defaultSettings = {
    ajaxsettings: {},
    uisettings: {}
};

Take a look at this site: http://www.json.org/

Also, you can try calling JSON.stringify() on one of your objects from the browser to see the json format. You'd have to do this in the console or a test page.

These paradigms don't have to be mutually exclusive. If you look at python, it supports functions and classes, but at the same time, everything is an object, including functions. You can mix and match functional/oop/procedural style all in one piece of code.

What I mean is, in functional languages (at least in Haskell, the only one I studied) there are no statements! functions are only allowed one expression inside them!! BUT, functions are first-class citizens, you can pass them around as parameters, along with a bunch of other abilities. They can do powerful things with few lines of code.

While in a procedural language like C, the only way you can pass functions around is by using function pointers, and that alone doesn't enable many powerful tasks.

In python, a function is a first-class citizen, but it can contain arbitrary number of statements. So you can have a function that contains procedural code, but you can pass it around just like functional languages.

Same goes for OOP. A language like Java doesn't allow you to write procedures/functions outside of a class. The only way to pass a function around is to wrap it in an object that implements that function, and then pass that object around.

In Python, you don't have this restriction.

You can do:

mylist.append(str(today))

Unfortunately oracle doesnot support auto_increment like mysql does. You need to put a little extra effort to get that.

say this is your table -

CREATE TABLE MYTABLE (
  ID NUMBER NOT NULL,
  NAME VARCHAR2(100)
  CONSTRAINT "PK1" PRIMARY KEY (ID)
);

You will need to create a sequence -

CREATE SEQUENCE S_MYTABLE
START WITH 1
INCREMENT BY 1
CACHE 10;

and a trigger -

CREATE OR REPLACE TRIGGER T_MYTABLE_ID
BEFORE INSERT
ON MYTABLE
REFERENCING NEW AS NEW
FOR EACH ROW
BEGIN
  if(:new.ID is null) then
  SELECT S_MYTABLE.nextval
  INTO :new.ID
  FROM dual;
  end if;
END;
/

ALTER TRIGGER "T_MYTABLE_ID" ENABLE;

For most use cases, it's not correct to register MultipartFilter in web.xml because Spring MVC already does the work of processing your multipart request. It's even written in the filter's javadoc.

On the server side, define a multipartResolver bean in your app context:

@Bean
public CommonsMultipartResolver multipartResolver(){
    CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver();
    commonsMultipartResolver.setDefaultEncoding("utf-8");
    commonsMultipartResolver.setMaxUploadSize(50000000);
    return commonsMultipartResolver;
}

On the client side, here's how to prepare the request for use with Spring RestTemplate API:

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.MULTIPART_FORM_DATA);

    LinkedMultiValueMap<String, String> pdfHeaderMap = new LinkedMultiValueMap<>();
    pdfHeaderMap.add("Content-disposition", "form-data; name=filex; filename=" + file.getOriginalFilename());
    pdfHeaderMap.add("Content-type", "application/pdf");
    HttpEntity<byte[]> doc = new HttpEntity<byte[]>(file.getBytes(), pdfHeaderMap);

    LinkedMultiValueMap<String, Object> multipartReqMap = new LinkedMultiValueMap<>();
    multipartReqMap.add("filex", doc);

    HttpEntity<LinkedMultiValueMap<String, Object>> reqEntity = new HttpEntity<>(multipartReqMap, headers);
    ResponseEntity<MyResponse> resE = restTemplate.exchange(uri, HttpMethod.POST, reqEntity, MyResponse.class);

The important thing is really to provide a Content-disposition header using the exact case, and adding name and filename specifiers, otherwise your part will be discarded by the multipart resolver.

Then, your controller method can handle the uploaded file with the following argument:

@RequestParam("filex") MultipartFile file

Hope this helps.

What about invoke-item script.bat.

If you want to kill -9 based on a string (you might want to try kill first) you can do something like this:

ps axf | grep <process name> | grep -v grep | awk '{print "kill -9 " $1}'

This will show you what you're about to kill (very, very important) and just pipe it to sh when the time comes to execute:

ps axf | grep <process name> | grep -v grep | awk '{print "kill -9 " $1}' | sh

The ARM architecture was originally designed for Acorn personal computers (See Acorn Archimedes, circa 1987, and RiscPC), which were just as much keyboard-based personal computers as were x86 based IBM PC models. Only later ARM implementations were primarily targeted at the mobile and embedded market segment.

Originally, simple RISC CPUs of roughly equivalent performance could be designed by much smaller engineering teams (see Berkeley RISC) than those working on the x86 development at Intel.

But, nowadays, the fastest ARM chips have very complex multi-issue out-of-order instruction dispatch units designed by large engineering teams, and x86 cores may have something like a RISC core fed by an instruction translation unit.

So, any current differences between the two architectures are more related to the specific market needs of the product niches that the development teams are targeting. (Random opinion: ARM probably makes more in license fees from embedded applications that tend to be far more power and cost constrained. And Intel needs to maintain a performance edge in PCs and servers for their profit margins. Thus you see differing implementation optimizations.)

Although many correct answers have already been given, the classical (read non-DOM) approach would be like this:

document.forms['yourform']['yourtextarea'].value = 'yourvalue';

where in the HTML your textarea is nested somewhere in a form like this:

<form name="yourform">
    <textarea name="yourtextarea" rows="10" cols="60"></textarea>
</form>

And as it happens, that would work with Netscape Navigator 4 and Internet Explorer 3 too. And, not unimportant, Internet Explorer on mobile devices.

You need to use parentheses: myList.insert([1, 2, 3]). When you leave out the parentheses, python thinks you are trying to access myList.insert at position 1, 2, 3, because that's what brackets are used for when they are right next to a variable.

IMO this link from Yochai Timmer was very good and relevant but painful to read. I wrote a summary.

Yochai, if you ever read this, please see the note at the end.

For the original post read : warning LNK4098: defaultlib "LIBCD" conflicts with use of other libs

Error

LINK : warning LNK4098: defaultlib "LIBCD" conflicts with use of other libs; use /NODEFAULTLIB:library

Meaning

one part of the system was compiled to use a single threaded standard (libc) library with debug information (libcd) which is statically linked

while another part of the system was compiled to use a multi-threaded standard library without debug information which resides in a DLL and uses dynamic linking

How to resolve

• Ignore the warning, after all it is only a warning. However, your program now contains multiple instances of the same functions.

• Use the linker option /NODEFAULTLIB:lib. This is not a complete solution, even if you can get your program to link this way you are ignoring a warning sign: the code has been compiled for different environments, some of your code may be compiled for a single threaded model while other code is multi-threaded.

• [...] trawl through all your libraries and ensure they have the correct link settings

In the latter, as it in mentioned in the original post, two common problems can arise :

• You have a third party library which is linked differently to your application.

• You have other directives embedded in your code: normally this is the MFC. If any modules in your system link against MFC all your modules must nominally link against the same version of MFC.

For those cases, ensure you understand the problem and decide among the solutions.

Note : I wanted to include that summary of Yochai Timmer's link into his own answer but since some people have trouble to review edits properly I had to write it in a separate answer. Sorry

Depends on what it's doing. If it has parameters, pass in mocks that you could ask later on if they have been called with the right set of parameters.

Since GNU Make version 4.0, the --trace argument is a nice way to tell what and why a makefile do, outputing lines like:

makefile:8: target 'foo.o' does not exist

or

makefile:12: update target 'foo' due to: bar

I couldn't find any good information on this, so I did some trial and error. The following attributes and fields (and only these) are recognized by Jenkins (v1.585).

<?xml version="1.0" encoding="UTF-8"?>

  <!-- if your classname does not include a dot, the package defaults to "(root)" -->
  <testcase name="my testcase" classname="my package.my classname" time="29">

    <!-- If the test didn't pass, specify ONE of the following 3 cases -->

    <!-- option 1 --> <skipped />
    <!-- option 2 --> <failure message="my failure message">my stack trace</failure>
    <!-- option 3 --> <error message="my error message">my crash report</error>

(I started with this sample XML document and worked backwards from there.)

I can think of a handy use for the custom tag "init". Include a JavaScript expression that gets evaluated at document.onLoad() time and provides a value for the tag, e.g.

<p>&lt;p&gt;The UTC date is &lt;span init="new Date().toUTCString()"&gt;?&lt;/span&gt;.&lt;p&gt;</p>

Some boilerplate JavaScript code would scan all the tags in the DOM at document.onload() time looking for the init attributes, evaluating the expressions that they contain, and assigning them to the containing tag's innerHTML. This would give HTML some of the power of JSP, PHP etc. Currently we have to split the HTML markup and the JavaScript code that illuminates it. Bugs love split code.

Sign-off is a requirement for getting patches into the Linux kernel and a few other projects, but most projects don't actually use it.

It was introduced in the wake of the SCO lawsuit, (and other accusations of copyright infringement from SCO, most of which they never actually took to court), as a Developers Certificate of Origin. It is used to say that you certify that you have created the patch in question, or that you certify that to the best of your knowledge, it was created under an appropriate open-source license, or that it has been provided to you by someone else under those terms. This can help establish a chain of people who take responsibility for the copyright status of the code in question, to help ensure that copyrighted code not released under an appropriate free software (open source) license is not included in the kernel.

For the original question based on Bootstrap 3, the solution was to use push-pull.

In Bootstrap 4 it's now possible to change the order, even when the columns are full-width stacked vertically, thanks to Bootstrap 4 flexbox. OFC, the push pull method will still work, but now there are other ways to change column order in Bootstrap 4, making it possible to re-order full-width columns.

Method 1 - Use flex-column-reverse for xs screens:

<div class="row flex-column-reverse flex-md-row">
    <div class="col-md-3">
        sidebar
    </div>
    <div class="col-md-9">
        main
    </div>
</div>

Method 2 - Use order-first for xs screens:

<div class="row">
    <div class="col-md-3">
        sidebar
    </div>
    <div class="col-md-9 order-first order-md-last">
        main
    </div>
</div>

Bootstrap 4(alpha 6): http://www.codeply.com/go/bBMOsvtJhD
Bootstrap 4.1: https://www.codeply.com/go/e0v77yGtcr

Original 3.x Answer

For the original question based on Bootstrap 3, the solution was to use push-pull for the larger widths, and then the columns will show is their natural order on smaller (xs) widths. (A-B reverse to B-A).

<div class="container">
    <div class="row">
        <div class="col-md-9 col-md-push-3">
            main
        </div>
        <div class="col-md-3 col-md-pull-9">
            sidebar
        </div>
    </div>
</div>

Bootstrap 3: http://www.codeply.com/go/wgzJXs3gel

@emre stated, "You cannot change the order of columns in smaller screens but you can do that in large screens". However, this should be clarified to state: "You cannot change the order of full-width "stacked" columns.." in Bootstrap 3.

for me all the combinations worked fine with below code snipplet , the snippet is for Angular-2 implementation , if you need to add days , pass positive numberofDays , if you need to substract pass negative numberofDays

function addSubstractDays(date: Date, numberofDays: number): Date {
let d = new Date(date);
return new Date(
    d.getFullYear(),
    d.getMonth(),
    (d.getDate() + numberofDays)
);
}

The same project (Android Studio 3.3.2, gradle-4.10.1-all.zip, compileSdkVersion 28, buildToolsVersion '28.0.3') works fine on the new fast Windows machine and underline Java 8 stuff by red color on the old Ubuntu 18.04 laptop (however project is compiling without errors on Ubuntu).

The only two things I have changed to force it to stop underlining by red were excluding of incremental true and dexOptions

compileOptions {
//    incremental true
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

//dexOptions {
//    javaMaxHeapSize "4g"
//}

in the app- level build.gradle.

This is my favourite way of decoding HTML characters. The advantage of using this code is that tags are also preserved.

function decodeHtml(html) {
    var txt = document.createElement("textarea");
    txt.innerHTML = html;

}

Rather than using JavaScript perhaps try something like

<a href="#">

  <input type="submit" value="save" style="background: transparent none; border: 0px none; text-decoration: inherit; color: inherit; cursor: inherit" />

</a>

This is caused by JAVA_HOME not being set correctly. It can be easily resolved by following the steps in this article.

A very typical approach to this type of problem is to use row_number():

select t.*
from (select t.*,
             row_number() over (partition by number order by id) as seqnum
      from t
     ) t
where seqnum = 1;

This is more generalizable than using a comparison to the minimum id. For instance, you can get a random row by using order by newid(). You can select 2 rows by using where seqnum <= 2.

I am not an expert. If you are getting ORA-01017 while trying to connect HR schema from SQL Developer in Oracle 11g Please try to unlock the HR as follows

alter user HR identified by hr DEFAULT tablespace users temporary tablespace temp account unlock;

The operators <- and = assign into the environment in which they are evaluated. The operator <- can be used anywhere, whereas the operator = is only allowed at the top level (e.g., in the complete expression typed at the command prompt) or as one of the subexpressions in a braced list of expressions.

I guess your entity_property has a composite key (entity_id, name) where entity_id is a foreign key to entity. If so, you can map it as follows:

@Embeddable
public class EntityPropertyPK {
    @Column(name = "name")
    private String name;

    @ManyToOne
    @JoinColumn(name = "entity_id")
    private Entity entity;

    ...
}

@Entity 
@Table(name="entity_property") 
public class EntityProperty { 
    @EmbeddedId
    private EntityPropertyPK id;

    @Column(name = "value")
    private String value; 

    ...
}

You don't need jQuery for that, you can do it with normal javascript:

http://www.w3schools.com/jsref/jsref_split.asp

var str = "a,b,c,d";
var res = str.split(","); // this returns an array

Just as Oded has answered. You need to have this sort of detection functionality in javascript.

I've struggled with this myself and realized that the offset is not enough. It does not give you any information about daylight saving for example. I ended up writing some code to map to zoneinfo database keys.

By checking several dates around a year you can more accurately determine a timezone.

Try the script here: http://jsfiddle.net/pellepim/CsNcf/

Simply change your system timezone and click run to test it. If you are running chrome you need to do each test in a new tab though (and safar needs to be restarted to pick up timezone changes).

If you want more details of the code check out: https://bitbucket.org/pellepim/jstimezonedetect/

I finally created a module to get this question (partially) resolved. Basically this module rewrites http.request function, added the proxy setting then fire. Check my blog post: https://web.archive.org/web/20160110023732/http://blog.shaunxu.me:80/archive/2013/09/05/semi-global-proxy-setting-for-node.js.aspx

I have built a performance framework that manipulates and graphs millions of datasets, and even then, the javascript calculation latency was on order of tens of milliseconds. Unless you're worried about going over the array size limit, I don't think you have much to worry about.

What other folks posted here mainly worked, but using onchange doesn't work when I change the number using arrows in the same direction more than once. What did work was oninput. My code (mainly borrowing from MC9000):

HTML

<input class="form-control" oninput="setTwoNumberDecimal(this)" step="0.01" value="0.00" type="number" name="item[amount]" id="item_amount">

JS

function setTwoNumberDecimal(el) {
        el.value = parseFloat(el.value).toFixed(2);
    };

So a Mixed Solution from @nvdo and @Abdelhameed Mahmoud worked for me

footer {
    position: sticky;
    height: 100px;
    top: calc( 100vh - 100px );
}

sp_addlinkedserver('servername')

so its should go like this -

select * from table1
unionall
select * from [server1].[database].[dbo].[table1]

Update PHP 7.4

Curly brace access syntax is deprecated since PHP 7.4

Update 2019

Moving on to the best practices of OOPS, @MrTrick's answer must be marked as correct, although my answer provides a hacked solution its not the best method.

Simply iterate its using {}

Example:

$videos{0}->id

This way your object is not destroyed and you can easily iterate through object.

For PHP 5.6 and below use this

$videos{0}['id']

Both array() and the stdClass objects can be accessed using the current() key() next() prev() reset() end() functions.

So, if your object looks like

object(stdClass)#19 (3) {
  [0]=>
  object(stdClass)#20 (22) {
    ["id"]=>
    string(1) "123"
  etc...

Then you can just do;

$id = reset($obj)->id; //Gets the 'id' attr of the first entry in the object

If you need the key for some reason, you can do;

reset($obj); //Ensure that we're at the first element
$key = key($obj);

Hope that works for you. :-) No errors, even in super-strict mode, on PHP 5.4

2022 Update:
After PHP 7.4, using current(), end(), etc functions on objects is deprecated.

In newer versions of PHP, use the ArrayIterator class:

$objIterator = new ArrayIterator($obj);

$id = $objIterator->current()->id; // Gets the 'id' attr of the first entry in the object

$key = $objIterator->key(); // and gets the key

This is not a bug in either implementation. There is no requirement to escape U+00B0. To quote the RFC:

2.5. Strings

The representation of strings is similar to conventions used in the C family of programming languages. A string begins and ends with quotation marks. All Unicode characters may be placed within the quotation marks except for the characters that must be escaped: quotation mark, reverse solidus, and the control characters (U+0000 through U+001F).

Any character may be escaped.

Escaping everything inflates the size of the data (all code points can be represented in four or fewer bytes in all Unicode transformation formats; whereas encoding them all makes them six or twelve bytes).

It is more likely that you have a text transcoding bug somewhere in your code and escaping everything in the ASCII subset masks the problem. It is a requirement of the JSON spec that all data use a Unicode encoding.

In the below investigation as API, I use http://example.com instead of http://myApiUrl/login from your question, because this first one working.

I assume that your page is on http://my-site.local:8088.

The reason why you see different results is that Postman:

• set header Host=example.com (your API)
• NOT set header Origin

This is similar to browsers' way of sending requests when the site and API has the same domain (browsers also set the header item Referer=http://my-site.local:8088, however I don't see it in Postman). When Origin header is not set, usually servers allow such requests by default.

This is the standard way how Postman sends requests. But a browser sends requests differently when your site and API have different domains, and then CORS occurs and the browser automatically:

• sets header Host=example.com (yours as API)
• sets header Origin=http://my-site.local:8088 (your site)

(The header Referer has the same value as Origin). And now in Chrome's Console & Networks tab you will see:

When you have Host != Origin this is CORS, and when the server detects such a request, it usually blocks it by default.

Origin=null is set when you open HTML content from a local directory, and it sends a request. The same situation is when you send a request inside an <iframe>, like in the below snippet (but here the Host header is not set at all) - in general, everywhere the HTML specification says opaque origin, you can translate that to Origin=null. More information about this you can find here.

fetch('http://example.com/api', {method: 'POST'});

Look on chrome-console > network tab

If you do not use a simple CORS request, usually the browser automatically also sends an OPTIONS request before sending the main request - more information is here. The snippet below shows it:

fetch('http://example.com/api', {_x000D_
  method: 'POST',_x000D_
  headers: { 'Content-Type': 'application/json'}_x000D_
});

Look in chrome-console -> network tab to 'api' request._x000D_
This is the OPTIONS request (the server does not allow sending a POST request)

You can change the configuration of your server to allow CORS requests.

Here is an example configuration which turns on CORS on nginx (nginx.conf file) - be very careful with setting always/"$http_origin" for nginx and "*" for Apache - this will unblock CORS from any domain.

location ~ ^/index\.php(/|$) {_x000D_
   ..._x000D_
    add_header 'Access-Control-Allow-Origin' "$http_origin" always;_x000D_
    add_header 'Access-Control-Allow-Credentials' 'true' always;_x000D_
    if ($request_method = OPTIONS) {_x000D_
        add_header 'Access-Control-Allow-Origin' "$http_origin"; # DO NOT remove THIS LINES (doubled with outside 'if' above)_x000D_
        add_header 'Access-Control-Allow-Credentials' 'true';_x000D_
        add_header 'Access-Control-Max-Age' 1728000; # cache preflight value for 20 days_x000D_
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';_x000D_
        add_header 'Access-Control-Allow-Headers' 'My-First-Header,My-Second-Header,Authorization,Content-Type,Accept,Origin';_x000D_
        add_header 'Content-Length' 0;_x000D_
        add_header 'Content-Type' 'text/plain charset=UTF-8';_x000D_
        return 204;_x000D_
    }_x000D_
}

Here is an example configuration which turns on CORS on Apache (.htaccess file)

# ------------------------------------------------------------------------------_x000D_

You can use onclick to run some JavaScript or jQuery code before submitting the form like this:

<script type="text/javascript">
    beforeSubmit = function(){
        if (1 == 1){
            //your before submit logic
        }        
        $("#formid").submit();            
    }
</script>
<input type="button" value="Click" onclick="beforeSubmit();" />

When you start tomcat independently and type http://localhost:8080/, tomcat show its default page (tomcat has its default page at TOMCAT_ROOT_DIRECTORY\webapps\ROOT\index.jsp).

When you start tomcat from eclipse, eclipse doesn't have any default page for url http://localhost:8080/ so it show error message. This doesn't mean that tomcat7 is not running.when you put your project specific url like http://localhost:8080/PROJECT_NAME_YOU_HAVE_CREATE_USING_ECLIPSE will display the default page of your web project.

With ECMAScript 6 there is a better way.

You can use computed property names in object property definitions, for example:

var name1 = 'John'; 
var value1 = '42'; 
var name2 = 'Sarah'; 
var value2 = '35';

var ipID = { 
             [name1] : value1, 
             [name2] : value2 
           }

This is equivalent to the following, where you have variables for the property names.

var ipID = { 
             John: '42', 
             Sarah: '35' 
           }

Here is a simple way to do it:

Math.round(value * 100) / 100

You might want to go ahead and make a separate function to do it for you though:

function roundToTwo(value) {
    return(Math.round(value * 100) / 100);
}

Then you would simply pass in the value.

You could enhance it to round to any arbitrary number of decimals by adding a second parameter.

function myRound(value, places) {
    var multiplier = Math.pow(10, places);

    return (Math.round(value * multiplier) / multiplier);
}

Introduction

It represents the scope (the lifetime) of the bean. This is easier to understand if you are familiar with "under the covers" working of a basic servlet web application: How do servlets work? Instantiation, sessions, shared variables and multithreading.

@Request/View/Flow/Session/ApplicationScoped

A @RequestScoped bean lives as long as a single HTTP request-response cycle (note that an Ajax request counts as a single HTTP request too). A @ViewScoped bean lives as long as you're interacting with the same JSF view by postbacks which call action methods returning null/void without any navigation/redirect. A @FlowScoped bean lives as long as you're navigating through the specified collection of views registered in the flow configuration file. A @SessionScoped bean lives as long as the established HTTP session. An @ApplicationScoped bean lives as long as the web application runs. Note that the CDI @Model is basically a stereotype for @Named @RequestScoped, so same rules apply.

Which scope to choose depends solely on the data (the state) the bean holds and represents. Use @RequestScoped for simple and non-ajax forms/presentations. Use @ViewScoped for rich ajax-enabled dynamic views (ajaxbased validation, rendering, dialogs, etc). Use @FlowScoped for the "wizard" ("questionnaire") pattern of collecting input data spread over multiple pages. Use @SessionScoped for client specific data, such as the logged-in user and user preferences (language, etc). Use @ApplicationScoped for application wide data/constants, such as dropdown lists which are the same for everyone, or managed beans without any instance variables and having only methods.

Abusing an @ApplicationScoped bean for session/view/request scoped data would make it to be shared among all users, so anyone else can see each other's data which is just plain wrong. Abusing a @SessionScoped bean for view/request scoped data would make it to be shared among all tabs/windows in a single browser session, so the enduser may experience inconsitenties when interacting with every view after switching between tabs which is bad for user experience. Abusing a @RequestScoped bean for view scoped data would make view scoped data to be reinitialized to default on every single (ajax) postback, causing possibly non-working forms (see also points 4 and 5 here). Abusing a @ViewScoped bean for request, session or application scoped data, and abusing a @SessionScoped bean for application scoped data doesn't affect the client, but it unnecessarily occupies server memory and is plain inefficient.

Note that the scope should rather not be chosen based on performance implications, unless you really have a low memory footprint and want to go completely stateless; you'd need to use exclusively @RequestScoped beans and fiddle with request parameters to maintain the client's state. Also note that when you have a single JSF page with differently scoped data, then it's perfectly valid to put them in separate backing beans in a scope matching the data's scope. The beans can just access each other via @ManagedProperty in case of JSF managed beans or @Inject in case of CDI managed beans.

• Difference between View and Request scope in managed beans
• Advantages of using JSF Faces Flow instead of the normal navigation system
• Communication in JSF2 - Managed bean scopes

@CustomScoped/NoneScoped/Dependent

It's not mentioned in your question, but (legacy) JSF also supports @CustomScoped and @NoneScoped, which are rarely used in real world. The @CustomScoped must refer a custom Map<K, Bean> implementation in some broader scope which has overridden Map#put() and/or Map#get() in order to have more fine grained control over bean creation and/or destroy.

The JSF @NoneScoped and CDI @Dependent basically lives as long as a single EL-evaluation on the bean. Imagine a login form with two input fields referring a bean property and a command button referring a bean action, thus with in total three EL expressions, then effectively three instances will be created. One with the username set, one with the password set and one on which the action is invoked. You normally want to use this scope only on beans which should live as long as the bean where it's being injected. So if a @NoneScoped or @Dependent is injected in a @SessionScoped, then it will live as long as the @SessionScoped bean.

• Expire specific managed bean instance after time interval
• what is none scope bean and when to use it?
• What is the default Managed Bean Scope in a JSF 2 application?

Flash scope

As last, JSF also supports the flash scope. It is backed by a short living cookie which is associated with a data entry in the session scope. Before the redirect, a cookie will be set on the HTTP response with a value which is uniquely associated with the data entry in the session scope. After the redirect, the presence of the flash scope cookie will be checked and the data entry associated with the cookie will be removed from the session scope and be put in the request scope of the redirected request. Finally the cookie will be removed from the HTTP response. This way the redirected request has access to request scoped data which was been prepared in the initial request.

This is actually not available as a managed bean scope, i.e. there's no such thing as @FlashScoped. The flash scope is only available as a map via ExternalContext#getFlash() in managed beans and #{flash} in EL.

• Pass an object between @ViewScoped beans without using GET params
• CDI missing @ViewScoped and @FlashScoped

Here is the solution I came up with in my app.

In my LoginActivity, after successfully processing a login, I start the next one differently depending on the API level.

Intent i = new Intent(this, MainActivity.class);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
    startActivity(i);
    finish();
} else {
    startActivityForResult(i, REQUEST_LOGIN_GINGERBREAD);
}

Then in my LoginActivity's onActivityForResult method:

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB &&
        requestCode == REQUEST_LOGIN_GINGERBREAD &&
        resultCode == Activity.RESULT_CANCELED) {
    moveTaskToBack(true);
}

Finally, after processing a logout in any other Activity:

Intent i = new Intent(this, LoginActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(i);

When on Gingerbread, makes it so if I press the back button from MainActivity, the LoginActivity is immediately hidden. On Honeycomb and later, I just finish the LoginActivity after processing a login and it is properly recreated after processing a logout.

The examples above work fine when there is only one delimiter, but it doesn't scale well for multiple delimiters. Note that this will only work for SQL Server 2016 and above.

/*Some Sample Data*/
DECLARE @mytable TABLE ([id] VARCHAR(10), [name] VARCHAR(1000));
INSERT INTO @mytable
VALUES ('1','John/Smith'),('2','Jane/Doe'), ('3','Steve'), ('4','Bob/Johnson')


/*Split based on delimeter*/
SELECT P.id, [1] 'FirstName', [2] 'LastName', [3] 'Col3', [4] 'Col4'
FROM(
    SELECT A.id, X1.VALUE, ROW_NUMBER() OVER (PARTITION BY A.id ORDER BY A.id) RN
    FROM @mytable A
    CROSS APPLY STRING_SPLIT(A.name, '/') X1
    ) A
PIVOT (MAX(A.[VALUE]) FOR A.RN IN ([1],[2],[3],[4],[5])) P

Joshua Bloch has a talk about API design that covers how bad ones make boilerplate code necessary. (Minute 46 for reference to boilerplate, listening to this today)

EDIT (#1)

If I understand correctly, you wish to have everything in one page and execute it from the same page.

You can use the following code to send mail from a single page, for example index.php or contact.php

The only difference between this one and my original answer is the <form action="" method="post"> where the action has been left blank.

It is better to use header('Location: thank_you.php'); instead of echo in the PHP handler to redirect the user to another page afterwards.

Copy the entire code below into one file.

<?php 
if(isset($_POST['submit'])){
    $to = "[email protected]"; // this is your Email address
    $from = $_POST['email']; // this is the sender's Email address
    $first_name = $_POST['first_name'];
    $last_name = $_POST['last_name'];
    $subject = "Form submission";
    $subject2 = "Copy of your form submission";
    $message = $first_name . " " . $last_name . " wrote the following:" . "\n\n" . $_POST['message'];
    $message2 = "Here is a copy of your message " . $first_name . "\n\n" . $_POST['message'];

    $headers = "From:" . $from;
    $headers2 = "From:" . $to;
    mail($to,$subject,$message,$headers);
    mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender
    echo "Mail Sent. Thank you " . $first_name . ", we will contact you shortly.";
    // You can also use header('Location: thank_you.php'); to redirect to another page.
    }
?>

<!DOCTYPE html>
<head>
<title>Form submission</title>
</head>
<body>

<form action="" method="post">
First Name: <input type="text" name="first_name"><br>
Last Name: <input type="text" name="last_name"><br>
Email: <input type="text" name="email"><br>
Message:<br><textarea rows="5" name="message" cols="30"></textarea><br>
<input type="submit" name="submit" value="Submit">
</form>

</body>
</html> 

Original answer

I wasn't quite sure as to what the question was, but am under the impression that a copy of the message is to be sent to the person who filled in the form.

Here is a tested/working copy of an HTML form and PHP handler. This uses the PHP mail() function.

The PHP handler will also send a copy of the message to the person who filled in the form.

You can use two forward slashes // in front of a line of code if you're not going to use it.

For example: // $subject2 = "Copy of your form submission"; will not execute.

HTML FORM:

<!DOCTYPE html>
<head>
<title>Form submission</title>
</head>
<body>

<form action="mail_handler.php" method="post">
First Name: <input type="text" name="first_name"><br>
Last Name: <input type="text" name="last_name"><br>
Email: <input type="text" name="email"><br>
Message:<br><textarea rows="5" name="message" cols="30"></textarea><br>
<input type="submit" name="submit" value="Submit">
</form>

</body>
</html>

PHP handler (mail_handler.php)

(Uses info from HTML form and sends the Email)

<?php 
if(isset($_POST['submit'])){
    $to = "[email protected]"; // this is your Email address
    $from = $_POST['email']; // this is the sender's Email address
    $first_name = $_POST['first_name'];
    $last_name = $_POST['last_name'];
    $subject = "Form submission";
    $subject2 = "Copy of your form submission";
    $message = $first_name . " " . $last_name . " wrote the following:" . "\n\n" . $_POST['message'];
    $message2 = "Here is a copy of your message " . $first_name . "\n\n" . $_POST['message'];

    $headers = "From:" . $from;
    $headers2 = "From:" . $to;
    mail($to,$subject,$message,$headers);
    mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender
    echo "Mail Sent. Thank you " . $first_name . ", we will contact you shortly.";
    // You can also use header('Location: thank_you.php'); to redirect to another page.
    // You cannot use header and echo together. It's one or the other.
    }
?>

To send as HTML:

If you wish to send mail as HTML and for both instances, then you will need to create two separate sets of HTML headers with different variable names.

Read the manual on mail() to learn how to send emails as HTML:

• http://php.net/manual/en/function.mail.php

Footnotes:

• In regards to HTML5

You have to specify the URL of the service that will handle the submitted data, using the action attribute.

As outlined at https://www.w3.org/TR/html5/forms.html under 4.10.1.3 Configuring a form to communicate with a server. For complete information, consult the page.

Therefore, action="" will not work in HTML5.

The proper syntax would be:

• action="handler.xxx" or
• action="http://www.example.com/handler.xxx".

Note that xxx will be the extension of the type of file used to handle the process. This could be a .php, .cgi, .pl, .jsp file extension etc.

Consult the following Q&A on Stack if sending mail fails:

• PHP mail form doesn't complete sending e-mail

The error says it all, change:

ViewPager mPager = (ViewPager) findViewById(R.id.fieldspager);

to

final ViewPager mPager = (ViewPager) findViewById(R.id.fieldspager);

I don't know this particular library, but I've used very similar calls. So this is my best guess:

unsigned char digest[16];
const char* string = "Hello World";
struct MD5Context context;
MD5Init(&context);
MD5Update(&context, string, strlen(string));
MD5Final(digest, &context);

This will give you back an integer representation of the hash. You can then turn this into a hex representation if you want to pass it around as a string.

char md5string[33];
for(int i = 0; i < 16; ++i)
    sprintf(&md5string[i*2], "%02x", (unsigned int)digest[i]);

I was having a hard time finding a way to actually separate the dollar amount and the amount after the decimal. I think I figured it out mostly and thought to share if any of yall were having trouble

So basically...

if price is 1234.44... whole would be 1234 and decimal would be 44 or

if price is 1234.01... whole would be 1234 and decimal would be 01 or

if price is 1234.10... whole would be 1234 and decimal would be 10

and so forth

$price = 1234.44;

$whole = intval($price); // 1234
$decimal1 = $price - $whole; // 0.44000000000005 uh oh! that's why it needs... (see next line)
$decimal2 = round($decimal1, 2); // 0.44 this will round off the excess numbers
$decimal = substr($decimal2, 2); // 44 this removed the first 2 characters

if ($decimal == 1) { $decimal = 10; } // Michel's warning is correct...
if ($decimal == 2) { $decimal = 20; } // if the price is 1234.10... the decimal will be 1...
if ($decimal == 3) { $decimal = 30; } // so make sure to add these rules too
if ($decimal == 4) { $decimal = 40; }
if ($decimal == 5) { $decimal = 50; }
if ($decimal == 6) { $decimal = 60; }
if ($decimal == 7) { $decimal = 70; }

It works with System.Web.Mail (which is marked as obsolete):

private const string SMTP_SERVER        = "http://schemas.microsoft.com/cdo/configuration/smtpserver";
private const string SMTP_SERVER_PORT   = "http://schemas.microsoft.com/cdo/configuration/smtpserverport";

private const string SEND_USERNAME      = "http://schemas.microsoft.com/cdo/configuration/sendusername";
private const string SEND_PASSWORD      = "http://schemas.microsoft.com/cdo/configuration/sendpassword";

System.Web.Mail.MailMessage mail = new System.Web.Mail.MailMessage();

mail.Fields[SMTP_SERVER] = "tempurl.org";
mail.Fields[SMTP_SERVER_PORT] = 465;
mail.Fields[SEND_USING] = 2;
mail.Fields[SMTP_USE_SSL] = true;
mail.Fields[SMTP_AUTHENTICATE] = 1;

System.Web.Mail.SmtpMail.Send(mail);

What is your point of view regarding obsolete namespace usage?

It's really just a coding style. The compiler generates the exact same for both variants.

See also here for the performance question:

• Will using 'var' affect performance?

Swift 4 onwards

for i in stride(from: 5, to: 0, by: -1) {
    print(i)
}
//prints 5, 4, 3, 2, 1

for i in stride(from: 5, through: 0, by: -1) {
    print(i)
}
//prints 5, 4, 3, 2, 1, 0

You might try having that delete job operate by first inserting the key of each row to be deleted into a temp table like this pseudocode

create temporary table deletetemp (userid int);

insert into deletetemp (userid)
  select userid from onlineusers where datetime <= now - interval 900 second;

delete from onlineusers where userid in (select userid from deletetemp);

Breaking it up like this is less efficient but it avoids the need to hold a key-range lock during the delete.

Also, modify your select queries to add a where clause excluding rows older than 900 seconds. This avoids the dependency on the cron job and allows you to reschedule it to run less often.

Theory about the deadlocks: I don't have a lot of background in MySQL but here goes... The delete is going to hold a key-range lock for datetime, to prevent rows matching its where clause from being added in the middle of the transaction, and as it finds rows to delete it will attempt to acquire a lock on each page it is modifying. The insert is going to acquire a lock on the page it is inserting into, and then attempt to acquire the key lock. Normally the insert will wait patiently for that key lock to open up but this will deadlock if the delete tries to lock the same page the insert is using because thedelete needs that page lock and the insert needs that key lock. This doesn't seem right for inserts though, the delete and insert are using datetime ranges that don't overlap so maybe something else is going on.

The problem is not with the splitting but rather with the WriteLine. A \n in a string printed with WriteLine will produce an "extra" line.

Example

var text = 
  "somet interesting text\n" +
  "some text that should be in the same line\r\n" +
  "some text should be in another line";

string[] stringSeparators = new string[] { "\r\n" };
string[] lines = text.Split(stringSeparators, StringSplitOptions.None);
Console.WriteLine("Nr. Of items in list: " + lines.Length); // 2 lines
foreach (string s in lines)
{
   Console.WriteLine(s); //But will print 3 lines in total.
}

To fix the problem remove \n before you print the string.

Console.WriteLine(s.Replace("\n", ""));

my solution is this:

configurations.all {
    resolutionStrategy {
        force 'com.android.support:support-v4:27.1.0'
    }
}

This is a TypeScript, optionally recursive, optionally error logging and asynchronous solution. You can specify a regular expression for the file names you want to find.

I used fs-extra, because its an easy super set improvement on fs.

import * as FsExtra from 'fs-extra'

/**
 * Finds files in the folder that match filePattern, optionally passing back errors .
 * If folderDepth isn't specified, only the first level is searched. Otherwise anything up
 * to Infinity is supported.
 *
 * @static
 * @param {string} folder The folder to start in.
 * @param {string} [filePattern='.*'] A regular expression of the files you want to find.
 * @param {(Error[] | undefined)} [errors=undefined]
 * @param {number} [folderDepth=0]
 * @returns {Promise<string[]>}
 * @memberof FileHelper
 */
public static async findFiles(
    folder: string,
    filePattern: string = '.*',
    errors: Error[] | undefined = undefined,
    folderDepth: number = 0
): Promise<string[]> {
    const results: string[] = []

    // Get all files from the folder
    let items = await FsExtra.readdir(folder).catch(error => {
        if (errors) {
            errors.push(error) // Save errors if we wish (e.g. folder perms issues)
        }

        return results
    })

    // Go through to the required depth and no further
    folderDepth = folderDepth - 1

    // Loop through the results, possibly recurse
    for (const item of items) {
        try {
            const fullPath = Path.join(folder, item)

            if (
                FsExtra.statSync(fullPath).isDirectory() &&
                folderDepth > -1)
            ) {
                // Its a folder, recursively get the child folders' files
                results.push(
                    ...(await FileHelper.findFiles(fullPath, filePattern, errors, folderDepth))
                )
            } else {
                // Filter by the file name pattern, if there is one
                if (filePattern === '.*' || item.search(new RegExp(filePattern, 'i')) > -1) {
                    results.push(fullPath)
                }
            }
        } catch (error) {
            if (errors) {
                errors.push(error) // Save errors if we wish
            }
        }
    }

    return results
}

How about using FONT tag?

Like:

H<font color="red">E</font>LLO.

Can't show example here, because this site doesn't allow font tag use.

Span style is fast and easy too.

You can't use float inside flex container and the reason is that float property does not apply to flex-level boxes as you can see here Fiddle.

So if you want to position child element to right of parent element you can use margin-left: auto but now child element will also push other div to the right as you can see here Fiddle.

What you can do now is change order of elements and set order: 2 on child element so it doesn't affect second div

.parent {_x000D_
  display: flex;_x000D_
}_x000D_
.child {_x000D_
  margin-left: auto;_x000D_
  order: 2;_x000D_
}

<div class="parent">_x000D_
  <div class="child">Ignore parent?</div>_x000D_
  <div>another child</div>_x000D_
</div>

setRetainInstance() - Deprecated

As Fragments Version 1.3.0-alpha01

The setRetainInstance() method on Fragments has been deprecated. With the introduction of ViewModels, developers have a specific API for retaining state that can be associated with Activities, Fragments, and Navigation graphs. This allows developers to use a normal, not retained Fragment and keep the specific state they want retained separate, avoiding a common source of leaks while maintaining the useful properties of a single creation and destruction of the retained state (namely, the constructor of the ViewModel and the onCleared() callback it receives).

You should make tags their own table with a linking table.

items:
id    object
1     lamp  
2     table   
3     stool  
4     bench 

tags:
id     tag
1      furniture
2      chair

items_tags:
item_id tag_id
1       1
2       1
3       1
4       1
3       2
4       2

If the child is always going to be a specific tag then you could do it like this

function test(el)
{
 var children = el.getElementsByTagName('div');// any tag could be used here..

  for(var i = 0; i< children.length;i++)
  {
    if (children[i].getAttribute('id') == 'child') // any attribute could be used here
    {
     // do what ever you want with the element..  
     // children[i] holds the element at the moment..

    }
  }
}

This code generates some SQL which can achieve this on every table and column in the database:

SELECT
   'UPDATE ['+T.TABLE_SCHEMA+'].[' + T.TABLE_NAME + '] SET [' + COLUMN_NAME + '] = NULL 
   WHERE [' + COLUMN_NAME + '] = '''''
FROM 
    INFORMATION_SCHEMA.columns C
INNER JOIN
    INFORMATION_SCHEMA.TABLES T ON C.TABLE_NAME=T.TABLE_NAME AND C.TABLE_SCHEMA=T.TABLE_SCHEMA
WHERE 
    DATA_TYPE IN ('char','nchar','varchar','nvarchar')
AND C.IS_NULLABLE='YES'
AND T.TABLE_TYPE='BASE TABLE'

I have some experience at recovering from eclipse when it becomes unstartable for whatever reason, could these blog entries help you?

link (archived)

also search for "cannot start eclipse" (I am a new user, I can only post a single hyperlink, so I have to just ask that you search for the second :( sorry)

perhaps those allow you to recover your workspace as well, I hope it helps.

Yep,there is a way you could do it

1. Right click->Inspect->sources(tab)

2. Towards Your right there will be a "pause script execution button"

I hope it helps!Peace

• P.S:This is for the first time.From the second time onwards the dev tool loads automatically

No. You can't send headers after they were sent. Try to use hooks in wordpress

You might consider using the :checked selector, provided by jQuery. Something like this:

$('.pChk').click(function() {
    if( $('.pChk:checked').length > 0 ) {
        $("#ProjectListButton").show();
    } else {
        $("#ProjectListButton").hide();
    }
}); 

ALTER TABLE table_name RENAME TO new_table_name; works in MySQL as well.

Alternatively: RENAME TABLE table_name TO new_table_name;

Multiple rows with checkboxes and select all using useState() hooks. Requires minor implementation to adjust to own project.

    const data;
    const [ allToggled, setAllToggled ] = useState(false);
    const [ toggled, setToggled ] = useState(Array.from(new Array(data.length), () => false));
    const [ selected, setSelected ] = useState([]);

    const handleToggleAll = allToggled => {
        let selectAll = !allToggled;
        setAllToggled(selectAll);
        let toggledCopy = [];
        let selectedCopy = [];
        data.forEach(function (e, index) {
            toggledCopy.push(selectAll);
            if(selectAll) {
                selectedCopy.push(index);
            }
        });
        setToggled(toggledCopy);
        setSelected(selectedCopy);
    };

    const handleToggle = index => {
        let toggledCopy = [...toggled];
        toggledCopy[index] = !toggledCopy[index];
        setToggled(toggledCopy);
        if( toggledCopy[index] === false ){

While inserting multiple rows with a single INSERT statement is generally faster, it leads to a more complicated and often unsafe code. Below I present the best practices when it comes to inserting multiple records in one go using PHP.

To insert multiple new rows into the database at the same time, one needs to follow the following 3 steps:

1. Start transaction (disable autocommit mode)
2. Prepare INSERT statement
3. Execute it multiple times

Using database transactions ensures that the data is saved in one piece and significantly improves performance.

How to properly insert multiple rows using PDO

PDO is the most common choice of database extension in PHP and inserting multiple records with PDO is quite simple.

$pdo = new \PDO("mysql:host=localhost;dbname=test;charset=utf8mb4", 'user', 'password', [
    \PDO::ATTR_ERRMODE => \PDO::ERRMODE_EXCEPTION,
    \PDO::ATTR_EMULATE_PREPARES => false
]);

// Start transaction
$pdo->beginTransaction();

// Prepare statement
$stmt = $pdo->prepare('INSERT 
    INTO `pxlot` (realname,email,address,phone,status,regtime,ip) 
    VALUES (?,?,?,?,?,?,?)');

// Perform execute() inside a loop
// Sample data coming from a fictitious data set, but the data can come from anywhere
foreach ($dataSet as $data) {
    // All seven parameters are passed into the execute() in a form of an array
    $stmt->execute([$data['name'], $data['email'], $data['address'], getPhoneNo($data['name']), '0', $data['regtime'], $data['ip']]);
}

// Commit the data into the database
$pdo->commit();

How to properly insert multiple rows using mysqli

The mysqli extension is a little bit more cumbersome to use but operates on very similar principles. The function names are different and take slightly different parameters.

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new \mysqli('localhost', 'user', 'password', 'database');
$mysqli->set_charset('utf8mb4');

// Start transaction
$mysqli->begin_transaction();

// Prepare statement
$stmt = $mysqli->prepare('INSERT 
    INTO `pxlot` (realname,email,address,phone,status,regtime,ip) 
    VALUES (?,?,?,?,?,?,?)');

// Perform execute() inside a loop
// Sample data coming from a fictitious data set, but the data can come from anywhere
foreach ($dataSet as $data) {
    // mysqli doesn't accept bind in execute yet, so we have to bind the data first
    // The first argument is a list of letters denoting types of parameters. It's best to use 's' for all unless you need a specific type
    // bind_param doesn't accept an array so we need to unpack it first using '...'
    $stmt->bind_param('sssssss', ...[$data['name'], $data['email'], $data['address'], getPhoneNo($data['name']), '0', $data['regtime'], $data['ip']]);
    $stmt->execute();
}

// Commit the data into the database
$mysqli->commit();

Performance

Both extensions offer the ability to use transactions. Executing prepared statement with transactions greatly improves performance, but it's still not as good as a single SQL query. However, the difference is so negligible that for the sake of conciseness and clean code it is perfectly acceptable to execute prepared statements multiple times. If you need a faster option to insert many records into the database at once, then chances are that PHP is not the right tool.

Yes, there's GitHub Enterprise :)

Only problem is it's a bit pricey :(

Dim simply declares the value and the type.

Set assigns a value to the variable.

The reason can be lack of the word static in some:

final static Logger logging = Logger.getLogger(ProcessorTest.class);

If I make logger the instance field, I am getting exactly this very warning:

No appenders could be found for logger (org.apache.kafka.producer.Sender)

What is worse, the warning points not to ProcessorTest, where the mistake lives, but to an absolutely different class (Sender) as a source of problems. That class has correct set logger and need not any changes! We could look for the problem for ages!

Like this in simple way .

    $this->db->select('*');
    $this->db->from('certs');
    $this->db->where('certs.id NOT IN (SELECT id_cer FROM revokace)');

    return $this->db->get()->result();

I'd just like to add, and please correct me if I'm wrong, that when I embed the HTML5 version of the videos, it doesn't play ads on top.

Not sure if this will ever change. They're probably just trying to work out the best way to show ads on the HTML5 player.

a % b

in c++ default:

(-7/3) => -2
-2 * 3 => -6
so a%b => -1

(7/-3) => -2
-2 * -3 => 6
so a%b => 1

in python:

-7 % 3 => 2
7 % -3 => -2

in c++ to python:

(b + (a%b)) % b

Try and move/copy the file to a temp dir. If you can, it has no lock and you can safely work in the temp dir without getting locks. Else just try to move it again in x seconds.

You can do this dynamically that way:

mkdir($dirname);
@touch($dirname . "/.htaccess");
  $f = fopen($dirname . "/.htaccess", "w");
  fwrite($f, "deny from all");
fclose($f);

[xml]$xmlfile = '<xml> <Section name="BackendStatus"> <BEName BE="crust" Status="1" /> <BEName BE="pizza" Status="1" /> <BEName BE="pie" Status="1" /> <BEName BE="bread" Status="1" /> <BEName BE="Kulcha" Status="1" /> <BEName BE="kulfi" Status="1" /> <BEName BE="cheese" Status="1" /> </Section> </xml>'

foreach ($bename in $xmlfile.xml.Section.BEName) {
    if($bename.Status -eq 1){
        #Do something
    }
}

You need to go one level deeper in what you are retrieving.

The problem is that buttonClickedEvent is a member function and you need a pointer to member in order to invoke it.

Try this:

void (MyClass::*func)(int);
func = &MyClass::buttonClickedEvent;

And then when you invoke it, you need an object of type MyClass to do so, for example this:

(this->*func)(<argument>);

http://www.codeguru.com/cpp/cpp/article.php/c17401/C-Tutorial-PointertoMember-Function.htm

I quote from http://www.php.net/manual/en/language.oop5.visibility.php

Note: The PHP 4 method of declaring a variable with the var keyword is still supported for compatibility reasons (as a synonym for the public keyword). In PHP 5 before 5.1.3, its usage would generate an E_STRICT warning.

In Ubuntu the file path is ./opt/lampp/var/mysql

Some basics:

RTSP server can be used for dead source as well as for live source. RTSP protocols provides you commands (Like your VCR Remote), and functionality depends upon your implementation.

RTP is real time protocol used for transporting audio and video in real time. Transport used can be unicast, multicast or broadcast, depending upon transport address and port. Besides transporting RTP does lots of things for you like packetization, reordering, jitter control, QoS, support for Lip sync.....

In your case if you want broadcasting streaming server then you need both RTSP (for control) as well as RTP (broadcasting audio and video)

To start with you can go through sample code provided by live555

I tried to use dplyr::rename and I get an error:

occ_5d <- dplyr::rename(occ_5d, rowname='code_5d')
Error: Unknown column `code_5d` 
Call `rlang::last_error()` to see a backtrace

I instead used the base R function which turns out to be quite simple and effective:

names(occ_5d)[1] = "code_5d"

private static List<File> sortByLastModified(String dirPath) {
    List<File> files = listFilesRec(dirPath);
    Collections.sort(files, new Comparator<File>() {
        public int compare(File o1, File o2) {
            return Long.compare(o1.lastModified(), o2.lastModified());
        }
    });
    return files;
}

You can also load the content with cURL, if file_get_contents insn't enabled on your server.

Example:

$ch = curl_init();  

curl_setopt($ch,CURLOPT_URL,"http://feeds.bbci.co.uk/sport/0/football/rss.xml?edition=int");
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);

$output = curl_exec($ch);

curl_close($ch);

$items = simplexml_load_string($output);

The underlying connection was closed: An unexpected error occurred on a receive.

This problem occurs when the server or another network device unexpectedly closes an existing Transmission Control Protocol (TCP) connection. This problem may occur when a time-out value on the server or on the network device is set too low. To resolve this problem, see resolutions A, D, E, F, and O. The problem can also occur if the server resets the connection unexpectedly, such as if an unhandled exception crashes the server process. Analyze the server logs to see if this may be the issue.

Resolution

To resolve this problem, make sure that you are using the most recent version of the .NET Framework.

Add a method to the class to override the GetWebRequest method. This change lets you access the HttpWebRequest object. If you are using Microsoft Visual C#, the new method must be similar to the following.

class MyTestService:TestService.TestService
{
    protected override WebRequest GetWebRequest(Uri uri)
    {
        HttpWebRequest webRequest = (HttpWebRequest) base.GetWebRequest(uri);
        //Setting KeepAlive to false
        webRequest.KeepAlive = false;
        return webRequest;
    }
}

Excerpt from KB915599: You receive one or more error messages when you try to make an HTTP request in an application that is built on the .NET Framework 1.1 Service Pack 1.

One already exists. If you cannot get over the "Move" syntax of the System.IO namespace. There is a static class FileSystem within the Microsoft.VisualBasic.FileIO namespace that has both a RenameDirectory and RenameFile already within it.

As mentioned by SLaks, this is just a wrapper for Directory.Move and File.Move.

Easiest

eval(myvar)(parameter1, parameter2)

You don't have a function "pointer". You have a function "name".

While this works well, you will have a large number of folks telling you it's "insecure" or a "security risk".

You don't apply a binary mask to an image. You (optionally) use a binary mask in a processing function call to tell the function which pixels of the image you want to process. If I'm completely misinterpreting your question, you should add more detail to clarify.

You can try this tool I made:

Mr. Data Converter

It converts to JSON, XML and others.

It's all client side, too, so your data never leaves your computer.

FindBugs also puts a red-x against files/packages to indicate static code analysis errors.

Just a note. If you want to compare a string with "" ,in your case, use

If LEN(str) > 0 Then

or even just

If LEN(str) Then

instead.

You can use date filter to convert in date and display in specific format.

In .ts file (typescript):

let dateString = '1968-11-16T00:00:00' 
let newDate = new Date(dateString);

In HTML:

{{dateString |  date:'MM/dd/yyyy'}}

Below are some formats which you can implement :

Backend:

public todayDate = new Date();

HTML :

<select>
<option value=""></option>
<option value="MM/dd/yyyy">[{{todayDate | date:'MM/dd/yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy">[{{todayDate | date:'EEEE, MMMM d, yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm a'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm:ss a'}}]</option>
<option value="MM/dd/yyyy h:mm a">[{{todayDate | date:'MM/dd/yyyy h:mm a'}}]</option>
<option value="MM/dd/yyyy h:mm:ss a">[{{todayDate | date:'MM/dd/yyyy h:mm:ss a'}}]</option>
<option value="MMMM d">[{{todayDate | date:'MMMM d'}}]</option>   
<option value="yyyy-MM-ddTHH:mm:ss">[{{todayDate | date:'yyyy-MM-ddTHH:mm:ss'}}]</option>
<option value="h:mm a">[{{todayDate | date:'h:mm a'}}]</option>
<option value="h:mm:ss a">[{{todayDate | date:'h:mm:ss a'}}]</option>      
<option value="EEEE, MMMM d, yyyy hh:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy hh:mm:ss a'}}]</option>
<option value="MMMM yyyy">[{{todayDate | date:'MMMM yyyy'}}]</option> 
</select>

I really don't see the right answer to this anywhere

class MyClass(dict):
    
    def __init__(self, a_property):
        self[a_property] = a_property

All you are really having to do is define your own __init__ - that really is all that there is too it.

Another example (little more complex):

class MyClass(dict):

    def __init__(self, planet):
        self[planet] = planet
        info = self.do_something_that_returns_a_dict()
        if info:
            for k, v in info.items():
                self[k] = v

    def do_something_that_returns_a_dict(self):
        return {"mercury": "venus", "mars": "jupiter"}

This last example is handy when you want to embed some kind of logic.

Anyway... in short class GiveYourClassAName(dict) is enough to make your class act like a dict. Any dict operation you do on self will be just like a regular dict.

Boolean(Number(myVar))

or

!!+myVar

The interpretation of the backspace and carriage return characters is left to the software you use for display. A terminal emulator, when displaying \b would move the cursor one step back, and when displaying \r to the beginning of the line. If you print these characters somewhere else, like a text file, the software may choose. to do something else.

Don't forget to bind key attribute otherwise always last item will be deleted

Correct way to delete selected item from array:

Template

<div v-for="(item, index) in items" :key="item.id">
  <input v-model="item.value">
   <button @click="deleteItem(index)">
  delete
</button>

script

deleteItem(index) {
  this.items.splice(index, 1); \\OR   this.$delete(this.items,index)
 \\both will do the same
}

I used this for getting Date and Time in a fragment.

private Handler mHandler = new Handler(Looper.getMainLooper());
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    // Inflate the layout for this fragment
    View root = inflater.inflate(R.layout.fragment_head_screen, container, false);

    dateTextView =  root.findViewById(R.id.dateView);
    hourTv = root.findViewById(R.id.hourView);

        Thread thread = new Thread() {
        @Override
        public void run() {
            try {
                while (!isInterrupted()) {
                    Thread.sleep(1000);
                    mHandler.post(new Runnable() {
                        @Override
                        public void run() {
                            //Calendario para obtener fecha & hora
                            Date currentTime = Calendar.getInstance().getTime();
                            SimpleDateFormat date_sdf = new SimpleDateFormat("dd/MM/yyyy");
                            SimpleDateFormat hour_sdf = new SimpleDateFormat("HH:mm a");

                            String currentDate = date_sdf.format(currentTime);
                            String currentHour = hour_sdf.format(currentTime);

                            dateTextView.setText(currentDate);
                            hourTv.setText(currentHour);
                        }
                    });
                }
            } catch (InterruptedException e) {
                Log.v("InterruptedException", e.getMessage());
            }
        }
    };
}

Have a look at the content by type web part - http://codeplex.com/eoffice - probably the most flexible viewing web part.

As this is an old question, and Django techniques must have changed significantly since, this answer reflects Django version 1.4, and is most likely applicable for v 1.5.

Django by default uses relational databases; you should make use of 'em. Map friendships to database relations (foreign key constraints) with the use of ManyToManyField. Doing so allows you to use RelatedManagers for friendlists, which use smart querysets. You can use all available methods such as filter or values_list.

Using ManyToManyField relations and properties:

class MyDjangoClass(models.Model):
    name = models.CharField(...)
    friends = models.ManyToManyField("self")

    @property
    def friendlist(self):
        # Watch for large querysets: it loads everything in memory
        return list(self.friends.all())

You can access a user's friend list this way:

joseph = MyDjangoClass.objects.get(name="Joseph")
friends_of_joseph = joseph.friendlist

Note however that these relations are symmetrical: if Joseph is a friend of Bob, then Bob is a friend of Joseph.

I once got into the same situation, I solved it following way. I've only fulfilled the requirements of a hint box, you can make it more interactive by adding effects and other things on other events like on focus etc.

        }
        else
        {
            adminEmailHint.Visibility = Visibility.Hidden;
        }
    }

private void adminPassword_PasswordChanged(object sender, RoutedEventArgs e)
    {
        if (adminPassword.Password.Length == 0)
        {
            adminPasswordHint.Visibility = Visibility.Visible;
        }
        else
        {
            adminPasswordHint.Visibility = Visibility.Hidden;
        }
    }

The available answers led to the fact that I entered empty values into the database. I corrected this error by replacing the serialize () function with the following code.

$(document).ready(function(){

// When click the button.
$("#button").click(function() {

    // Assigning Variables to Form Fields
    var email = $("#email").val();

    // Send the form data using the ajax method
    $.ajax({
        data: "email=" + email,
        type: "post",
        url: "your_file.php",
        success: function(data){
            alert("Data Save: " + data);
        }
    });

});

});

In some systems one have to specify:

import os
os.environ["CUDA_DEVICE_ORDER"]="PCI_BUS_ID"
os.environ["CUDA_VISIBLE_DEVICES"]=""  # or even "-1"

BEFORE importing tensorflow.

C also does a good job at not making anything ambiguous.

Sure the dot could be overloaded to mean both things, but the arrow makes sure that the programmer knows that he's operating on a pointer, just like when the compiler won't let you mix two incompatible types.

You can completely control the execution of javascript functions (and pass variables between them) using custom jQuery events....I was told that this wasn't possible all over these forums, but I got something working that does exactly that (even using an ajax call).

Here's the answer (IMPORTANT: it's not the checked answer but rather the answer by me "Emile"):

How to get a variable returned across multiple functions - Javascript/jQuery

Calendar calendar = Calendar.getInstance();
calendar.setTime(new Date());
int mSec = calendar.get(Calendar.MILLISECOND);

For those who Googled "disable a button" but may have more nuanced use cases:

Disable with visual effect: As others have said, this will prevent the button from being pressed and the system will automatically make it look disabled:

yourButton.isEnabled = false 

Disable without visual effect: Are you using a button in a case where it should look normal but not behave likes button by reacting to touches? Try this!

yourButton.userInteractionEnabled = false

Hide without disabling: This approach hides the button without disabling it (invisible but can still be tapped):

 yourButton.alpha = 0.0

Remove: This will remove the view entirely:

 yourButton.removeFromSuperView()

Tap something behind a button: Have two buttons stacked and you want the top button to temporarily act like it's not there? If you won't need the top button again, remove it. If you will need it again, try condensing its height or width to 0!

You could fire an event into the quit() slot of your application even without connect(). This way, the event-loop does at least one turn and should process the events within your main()-logic:

#include <QCoreApplication>
#include <QTimer>

int main(int argc, char *argv[])
{
    QCoreApplication app( argc, argv );

    // do your thing, once

    QTimer::singleShot( 0, &app, &QCoreApplication::quit );
    return app.exec();
}

Don't forget to place CONFIG += console in your .pro-file, or set consoleApplication: true in your .qbs Project.CppApplication.

Careful:

$array = (array) $object;

does a shallow conversion ($object->innerObject = new stdClass() remains an object) and converting back and forth using json works but it's not a good idea if performance is an issue.

If you need all objects to be converted to associative arrays here is a better way to do that (code ripped from I don't remember where):

function toArray($obj)
{
    if (is_object($obj)) $obj = (array)$obj;
    if (is_array($obj)) {
        $new = array();
        foreach ($obj as $key => $val) {
            $new[$key] = toArray($val);
        }
    } else {
        $new = $obj;
    }

    return $new;
}

Well I tried all the above methods. None worked for me. The following worked for me:

1. Activate your environment
2. Download the .whl package manually from https://pypi.org/simple//
3. Navigate to the folder where you have downloaded the .whl from the command line with your environment activated
4. perform: pip install package_name_whatever.whl

Try Using DateTime::createFromFormat

$date = DateTime::createFromFormat('d/m/Y', "24/04/2012");
echo $date->format('Y-m-d');

Output

2012-04-24

EDIT:

If the date is 5/4/2010 (both D/M/YYYY or DD/MM/YYYY), this below method is used to convert 5/4/2010 to 2010-4-5 (both YYYY-MM-DD or YYYY-M-D) format.

$old_date = explode('/', '5/4/2010'); 
$new_data = $old_date[2].'-'.$old_date[1].'-'.$old_date[0];

OUTPUT:

2010-4-5

You can use this:

$("#id").click(function()
{
   $(this).data('clicked', true);
});

Now check it via an if statement:

if($("#id").data('clicked'))
{
   // code here 
}

For more information you can visit the jQuery website on the .data() function.
