Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

I ran into this as well - I did all of my development on a Lenovo IdeaTab A2107A-F and could run development builds on it, and even release signed APKs (installed with adb install) with no issues. Once it was published in Alpha test mode and available on Google Play I received the "incompatible with your device" error message.

It turns out I had placed in my AndroidManifest.xml the following from a tutorial:

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-permission android:name="android.permission.CAMERA" />

Well, the Lenovo IdeaTab A2107A-F doesn't have an autofocusing camera on it (which I learned from http://www.phonearena.com/phones/Lenovo-IdeaTab-A2107_id7611, under Cons: lacks autofocus camera). Regardless of whether I was using that feature, Google Play said no. Once that was removed I rebuilt my APK, uploaded it to Google Play, and sure enough my IdeaTab was now in the compatible devices list.

So, double-check every <uses-feature> and if you've been doing some copy-paste from the web check again. Odds are you requested some feature you aren't even using.

This is my version of a bash script. It takes database name as a parameter and converts all tables to another charset and collation (given by another parameters or default value defined in the script).

#!/bin/bash

# mycollate.sh <database> [<charset> <collation>]
# changes MySQL/MariaDB charset and collation for one database - all tables and
# all columns in all tables

DB="$1"
CHARSET="$2"
COLL="$3"

[ -n "$DB" ] || exit 1
[ -n "$CHARSET" ] || CHARSET="utf8mb4"
[ -n "$COLL" ] || COLL="utf8mb4_general_ci"

echo $DB
echo "ALTER DATABASE $DB CHARACTER SET $CHARSET COLLATE $COLL;" | mysql

echo "USE $DB; SHOW TABLES;" | mysql -s | (
    while read TABLE; do
        echo $DB.$TABLE
        echo "ALTER TABLE $TABLE CONVERT TO CHARACTER SET $CHARSET COLLATE $COLL;" | mysql $DB
    done
)

Solution using Google Guava, since I prefer it to Apache Commons-Lang:

/**
 * Returns a String with exactly the given length composed entirely of
 * the given character.
 * @param length the length of the returned string
 * @param c the character to fill the String with
 */
public static String stringOfLength(final int length, final char c)
{
    return Strings.padEnd("", length, c);
}

The question has changed, so to has the answer:

Strings can't be tested using math.isnan as this expects a float argument. In your countries list, you have floats and strings.

In your case the following should suffice:

cleanedList = [x for x in countries if str(x) != 'nan']

Old answer

In your countries list, the literal 'nan' is a string not the Python float nan which is equivalent to:

float('NaN')

In your case the following should suffice:

cleanedList = [x for x in countries if x != 'nan']

this is how you do it with ActionLIstener

import java.awt.FlowLayout;
import java.awt.event.*;

import javax.swing.*;

public class MyWind extends JFrame{

    public MyWind() {
        initialize();
    }

    private void initialize() {
        setSize(300, 300);
        setLayout(new FlowLayout(FlowLayout.LEFT));
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        final JTextField field = new JTextField();
        field.setSize(200, 50);
        field.setText("              ");

        JComboBox comboBox = new JComboBox();
        comboBox.setEditable(true);
        comboBox.addItem("item1");
        comboBox.addItem("item2");

        //
        // Create an ActionListener for the JComboBox component.
        //
        comboBox.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent event) {
                //
                // Get the source of the component, which is our combo
                // box.
                //
                JComboBox comboBox = (JComboBox) event.getSource();

                Object selected = comboBox.getSelectedItem();
                if(selected.toString().equals("item1"))
                field.setText("30");
                else if(selected.toString().equals("item2"))
                    field.setText("40");

            }
        });
        getContentPane().add(comboBox);
        getContentPane().add(field);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                new MyWind().setVisible(true);
            }
        });
    }
}

Use the backslash to escape a character. For example:

/\\d/

This will match \d instead of a numeric character

Unfortunately, (for practical and security reasons I guess), if you want to add/copy local content, it must be located under the same root path than the Dockerfile.

From the documentation:

The <src> path must be inside the context of the build; you cannot ADD ../something/something, because the first step of a docker build is to send the context directory (and subdirectories) to the docker daemon.

EDIT: There's now an option (-f) to set the path of your Dockerfile ; it can be used to achieve what you want, see @Boedy 's response.

You can change the name of the column, therefore instead of "COUNT(*)" you would have something meaningful. You will have to update your "RowCount.sql" script for that.

For example:

SQL> select count(*) as RecordCountFromTableOne from TableOne;

Will be displayed as:

RecordCountFromTableOne
-----------------------
           0

If you want to have space in the title, you need to enclose it in double quotes

SQL> select count(*) as "Record Count From Table One" from TableOne;

Will be displayed as:

Record Count From Table One
---------------------------
            0

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()

plt.subplots_adjust(hspace=0.35)
plt.show()

You can also send characters that you want to be trimed

extension String {


    func trim() -> String {

        return self.trimmingCharacters(in: .whitespacesAndNewlines)

    }

    func trim(characterSet:CharacterSet) -> String {

        return self.trimmingCharacters(in: characterSet)

    }
}

validationMessage = validationMessage.trim(characterSet: CharacterSet(charactersIn: ","))

Simplest - and I changed the checkbox class to ID as well:

$(function() {_x000D_
  $("#coupon_question").on("click",function() {_x000D_
    $(".answer").toggle(this.checked);_x000D_
  });_x000D_
});

.answer { display:none }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
<fieldset class="question">_x000D_
  <label for="coupon_question">Do you have a coupon?</label>_x000D_
  <input id="coupon_question" type="checkbox" name="coupon_question" value="1" />_x000D_
  <span class="item-text">Yes</span>_x000D_
</fieldset>_x000D_
_x000D_
<fieldset class="answer">_x000D_
  <label for="coupon_field">Your coupon:</label>_x000D_
  <input type="text" name="coupon_field" id="coupon_field" />_x000D_
</fieldset>

It is worth noting that sometimes you do want non-configurable "hard-coded" numbers in your code. There are a number of famous ones including 0x5F3759DF which is used in the optimized inverse square root algorithm.

In the rare cases where I find the need to use such Magic Numbers, I set them as a const in my code, and document why they are used, how they work, and where they came from.

None of the answers here satisfies my needs.

The answer from Muno is wrong because it lists ONLY the USB ports.

The answer from code4life is wrong because it lists all EXCEPT the USB ports. (Nevertheless it has 44 up-votes!!!)

I have an EPSON printer simulation port on my computer which is not listed by any of the answers here. So I had to write my own solution. Additionally I want to display more information than just the caption string. I also need to separate the port name from the description.

My code has been tested on Windows XP, Windows 7 and Windows 10.

The Port Name (like "COM1") must be read from the registry because WMI does not give this information for all COM ports (EPSON).

If you use my code you do not need SerialPort.GetPortNames() anymore. My function returns the same ports, but with additional details. Why did Microsoft not implement such a function into the framework??

using System.Management;
using Microsoft.Win32;

using (ManagementClass i_Entity = new ManagementClass("Win32_PnPEntity"))
{
    foreach (ManagementObject i_Inst in i_Entity.GetInstances())
    {
        Object o_Guid = i_Inst.GetPropertyValue("ClassGuid");
        if (o_Guid == null || o_Guid.ToString().ToUpper() != "{4D36E978-E325-11CE-BFC1-08002BE10318}")
            continue; // Skip all devices except device class "PORTS"

        String s_Caption  = i_Inst.GetPropertyValue("Caption")     .ToString();
        String s_Manufact = i_Inst.GetPropertyValue("Manufacturer").ToString();
        String s_DeviceID = i_Inst.GetPropertyValue("PnpDeviceID") .ToString();
        String s_RegPath  = "HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Enum\\" + s_DeviceID + "\\Device Parameters";
        String s_PortName = Registry.GetValue(s_RegPath, "PortName", "").ToString();

        int s32_Pos = s_Caption.IndexOf(" (COM");
        if (s32_Pos > 0) // remove COM port from description
            s_Caption = s_Caption.Substring(0, s32_Pos);

        Console.WriteLine("Port Name:    " + s_PortName);
        Console.WriteLine("Description:  " + s_Caption);
        Console.WriteLine("Manufacturer: " + s_Manufact);
        Console.WriteLine("Device ID:    " + s_DeviceID);
        Console.WriteLine("-----------------------------------");
    }
}

I tested the code with a lot of COM ports. This is the Console output:

COM1 is a COM port on the mainboard.

COM 8 and 9 are Buetooth COM ports.

COM 25 and 26 are USB to RS232 adapters.

COM 28 and 29 and 30 are Arduino-like boards.

COM 20 and 999 are EPSON ports.

You may already find your answer because it was some time ago you asked. But I tried to do something similar when coding ror. I wanted to run "rails server" in a new cmd window so I don't have to open a new cmd and then find my path again.

What I found out was to use the K switch like this:

start cmd /k echo Hello, World!

start before "cmd" will open the application in a new window and "/K" will execute "echo Hello, World!" after the new cmd is up.

You can also use the /C switch for something similar.

start cmd /C pause

This will then execute "pause" but close the window when the command is done. In this case after you pressed a button. I found this useful for "rails server", then when I shutdown my dev server I don't have to close the window after.

Use the following in your batch file:

start cmd.exe /c "more-batch-commands-here"

or

start cmd.exe /k "more-batch-commands-here"

/c Carries out the command specified by string and then terminates

/k Carries out the command specified by string but remains

The /c and /k options controls what happens once your command finishes running. With /c the terminal window will close automatically, leaving your desktop clean. With /k the terminal window will remain open. It's a good option if you want to run more commands manually afterwards.

Consult the cmd.exe documentation using cmd /? for more details.

Escaping Commands with White Spaces

The proper formatting of the command string becomes more complicated when using arguments with spaces. See the examples below. Note the nested double quotes in some examples.

Examples:

Run a program and pass a filename parameter:
CMD /c write.exe c:\docs\sample.txt

Run a program and pass a filename which contains whitespace:
CMD /c write.exe "c:\sample documents\sample.txt"

Spaces in program path:
CMD /c ""c:\Program Files\Microsoft Office\Office\Winword.exe""

Spaces in program path + parameters:
CMD /c ""c:\Program Files\demo.cmd"" Parameter1 Param2
CMD /k ""c:\batch files\demo.cmd" "Parameter 1 with space" "Parameter2 with space""

Launch demo1 and demo2:
CMD /c ""c:\Program Files\demo1.cmd" & "c:\Program Files\demo2.cmd""

Try the snipped which is mentioned below, it works for me also.

In my layout xml where I have my TabLayout, have added style to the TabLayout like below :

<android.support.design.widget.TabLayout
    android:id="@+id/tab_layout"
    style="@style/MyCustomTabLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:tabGravity="fill"
    app:tabMode="fixed" />

and in my style.xml I have defined the style that is used in my layout xml, check code for styles added below :

<style name="MyCustomTabLayout" parent="Widget.Design.TabLayout">
    <item name="android:background">YOUR BACKGROUND COLOR</item>
    <item name="tabTextAppearance">@style/MyCustomTabText</item>
    <item name="tabSelectedTextColor">SELECTED TAB TEXT COLOR</item>
    <item name="tabIndicatorColor">SELECTED TAB INDICATOR COLOR</item>
</style>

<style name="MyCustomTabText" parent="TextAppearance.AppCompat.Button">
    <item name="android:textSize">YOUR TEXT SIZE</item>
    <item name="android:textStyle">bold</item>
    <item name="android:textColor">@android:color/white</item>
</style>

I hope it will work for you.....

the line below shows you haven't set an DataAttribute like required on AgreementNumber

<input id="AgreementNumber" name="AgreementNumber" size="30" type="text" value="387893" />

you need

[Required]
public String AgreementNumber{get;set;}

I have tried the --assume-unchanged and also the .gitignore but neither worked well. They make it hard to switch branches and hard to merge changes from others. This is my solution:

When I commit, I manually remove the files from the list of changes

Before I pull, I stash the changed files. And after pull, I do a stash pop.

1. git stash
2. git pull
3. git stash pop

Step 3 sometimes will trigger a merge and may result in conflict that you need to resolve, which is a good thing.

This allows me to keep local changes that are not shared with others on the team.

npm install --global --production windows-build-tools

SelThroughJava's answer was very helpful I had to modify a bit to my code to be worked . I used https://mvnrepository.com/artifact/org.apache.poi/poi and https://mvnrepository.com/artifact/org.testng/testng as dependencies . Full code is given below with exact imports.

 import java.io.FileInputStream;
    import java.io.FileNotFoundException;

    public class ReadExcelFormulaValue {

        private static final CellType NUMERIC = null;
        public static void main(String[] args) {
            try {
                readFormula();
            } catch (IOException e) {
                // TODO Auto-generated catch block

            org.apache.poi.ss.usermodel.Sheet sheet = workbook.getSheetAt(0);

            FormulaEvaluator evaluator = workbook.getCreationHelper().createFormulaEvaluator();

            CellReference cellReference = new CellReference("G2"); // pass the cell which contains the formula
            Row row = sheet.getRow(cellReference.getRow());
            Cell cell = row.getCell(cellReference.getCol());

            CellValue cellValue = evaluator.evaluate(cell);

    }

The safest thing is have some clean virtual machine, on which you can test your program. On every version you'd like to test, restore the VM to its initial clean value. Then install your program using its setup, and see if it works.

Dll problems have different faces. If you use Visual Studio and dynamically link to the CRT, you have to distribute the CRT DLLs. Update your VS, and you have to distribute another version of the CRT. Just checking dependencies is not enough, as you might miss those. Doing a full install on a clean machine is the only safe solution, IMO.

If you don't want to setup a full-blown test environment and have Windows 7, you can use XP-Mode as the initial clean machine, and XP-More to duplicate the VM.

You could use Enumerable#select:

clients.select{|key, hash| hash["client_id"] == "2180" }
#=> [["orange", {"client_id"=>"2180"}]]

Note that the result will be an array of all the matching values, where each is an array of the key and value.

The content of the table/tables in PostgreSQL database can be deleted in several ways.

Deleting table content using sql:

Deleting content of one table:

TRUNCATE table_name;
DELETE FROM table_name;

Deleting content of all named tables:

TRUNCATE table_a, table_b, …, table_z;

Deleting content of named tables and tables that reference to them (I will explain it in more details later in this answer):

TRUNCATE table_a, table_b CASCADE;

Deleting table content using pgAdmin:

Deleting content of one table:

Right click on the table -> Truncate

Deleting content of table and tables that reference to it:

Right click on the table -> Truncate Cascaded

Difference between delete and truncate:

From the documentation:

DELETE deletes rows that satisfy the WHERE clause from the specified table. If the WHERE clause is absent, the effect is to delete all rows in the table. http://www.postgresql.org/docs/9.3/static/sql-delete.html

TRUNCATE is a PostgreSQL extension that provides a faster mechanism to remove all rows from a table. TRUNCATE quickly removes all rows from a set of tables. It has the same effect as an unqualified DELETE on each table, but since it does not actually scan the tables it is faster. Furthermore, it reclaims disk space immediately, rather than requiring a subsequent VACUUM operation. This is most useful on large tables. http://www.postgresql.org/docs/9.1/static/sql-truncate.html

Working with table that is referenced from other table:

When you have database that has more than one table the tables have probably relationship. As an example there are three tables:

create table customers (
customer_id int not null,
name varchar(20),
surname varchar(30),
constraint pk_customer primary key (customer_id)
);

create table orders (
order_id int not null,
number int not null,
customer_id int not null,
constraint pk_order primary key (order_id),
constraint fk_customer foreign key (customer_id) references customers(customer_id)
);

create table loyalty_cards (
card_id int not null,
card_number varchar(10) not null,
customer_id int not null,
constraint pk_card primary key (card_id),
constraint fk_customer foreign key (customer_id) references customers(customer_id)
);

And some prepared data for these tables:

insert into customers values (1, 'John', 'Smith');

insert into orders values 
(10, 1000, 1),
(11, 1009, 1),
(12, 1010, 1);        

insert into loyalty_cards values (100, 'A123456789', 1);

Table orders references table customers and table loyalty_cards references table customers. When you try to TRUNCATE / DELETE FROM the table that is referenced by other table/s (the other table/s has foreign key constraint to the named table) you get an error. To delete content from all three tables you have to name all these tables (the order is not important)

TRUNCATE customers, loyalty_cards, orders;

or just the table that is referenced with CASCADE key word (you can name more tables than just one)

TRUNCATE customers CASCADE;

The same applies for pgAdmin. Right click on customers table and choose Truncate Cascaded.

You can use the 'more' command to see the content of the file:

more filename.txt

You can use JavaScript to disable the context menu (right-click), but it's easily overwrittable. For example, in Firefox, go to Options -> Content and next to the "Enable JavaScript" check box, click Advanced. Uncheck the "Disable or replace context menus" option. Now you can right-click all you want.

A simple CTRL + U will view the source. That can never be disabled.

I had the same problem on Windows 10, after I moved my android-SDK folder to D:/ as I was low on space on c:/.

It turned out that the Android emulator looks for Android SDK via Global (environment) Variables, not the path defined inside Android Studio.

So I edited the Environment variable of ANDROID_HOME and that was it.

This is how I've tackled a similar issue in an ES6 context:

function merge(array1, array2, prop) {
    return array2.map(function (item2) {
        var item1 = array1.find(function (item1) {
            return item1[prop] === item2[prop];
        });
        return Object.assign({}, item1, item2);
    });
}

Note: This approach will not return any items from array1 that don't appear in array2.

EDIT: I have some scenarios where I want to preserve items that don't appear in the second array so I came up with another method.

function mergeArrays(arrays, prop) {
    const merged = {};

    arrays.forEach(arr => {
        arr.forEach(item => {
            merged[item[prop]] = Object.assign({}, merged[item[prop]], item);
        });
    });

    return Object.values(merged);
}

var arr1 = [
    { name: 'Bob', age: 11 },
    { name: 'Ben', age: 12 },
    { name: 'Bill', age: 13 },
];

var arr2 = [
    { name: 'Bob', age: 22 },
    { name: 'Fred', age: 24 },
    { name: 'Jack', age: 25 },
    { name: 'Ben' },
];

console.log(mergeArrays([arr1, arr2], 'name'));

I think it has a bad reputation with people who have the most simple and the most complicated projects.

If you're building a single WAR from a single codebase it forces you to move your project structure around and manually list the two of three jars into the POM file.

If you're building one EAR from a set of nine EAR file prototypes with some combination of five WAR files, three EJBs and 17 other tools, dependency jars and configurations that require tweaking MANIFEST.MF and XML files in existing resources during final build; then Maven is likely too restricting. Such a project becomes a mess of complicated nested profiles, properties files and misuse of the Maven build goals and Classifier designation.

So if you're in the bottom 10% of the complexity curve, its overkill. At the top 10% of that curve, you're in a straitjacket.

Maven's growth is because it works well for the middle 80%

recursion is your friend:

function __toObject(Array $arr) {
    $obj = new stdClass();
    foreach($arr as $key=>$val) {
        if (is_array($val)) {
            $val = __toObject($val);
        }
        $obj->$key = $val;
    }

    return $obj;
}

I test the several propositions by running them into a large loop. I used microsoft visual studio 2015 as compiler and my processor is an i7, 8Hz, 2GHz.

    long start = clock();
    int a = 0;
    //100000000
    std::string ret;
    for (int i = 0; i < 60000000; i++)
    {
        ret.append(1, ' ');
        //ret += ' ';
        //ret.push_back(' ');
        //ret.insert(ret.end(), 1, ' ');
        //ret.resize(ret.size() + 1, ' ');
    }
    long stop = clock();
    long test = stop - start;
    return 0;

According to this test, results are :

     operation             time(ms)            note
------------------------------------------------------------------------
append                     66015
+=                         67328      1.02 time slower than 'append'
resize                     83867      1.27 time slower than 'append'
push_back & insert         90000      more than 1.36 time slower than 'append'

Conclusion

+= seems more understandable, but if you mind about speed, use append

From the docs:

The comparison uses lexicographical ordering: first the first two items are compared, and if they differ this determines the outcome of the comparison; if they are equal, the next two items are compared, and so on, until either sequence is exhausted.

Also:

Lexicographical ordering for strings uses the Unicode code point number to order individual characters.

or on Python 2:

Lexicographical ordering for strings uses the ASCII ordering for individual characters.

As an example:

>>> 'abc' > 'bac'
False
>>> ord('a'), ord('b')
(97, 98)

The result False is returned as soon as a is found to be less than b. The further items are not compared (as you can see for the second items: b > a is True).

Be aware of lower and uppercase:

>>> [(x, ord(x)) for x in abc]
[('a', 97), ('b', 98), ('c', 99), ('d', 100), ('e', 101), ('f', 102), ('g', 103), ('h', 104), ('i', 105), ('j', 106), ('k', 107), ('l', 108), ('m', 109), ('n', 110), ('o', 111), ('p', 112), ('q', 113), ('r', 114), ('s', 115), ('t', 116), ('u', 117), ('v', 118), ('w', 119), ('x', 120), ('y', 121), ('z', 122)]
>>> [(x, ord(x)) for x in abc.upper()]
[('A', 65), ('B', 66), ('C', 67), ('D', 68), ('E', 69), ('F', 70), ('G', 71), ('H', 72), ('I', 73), ('J', 74), ('K', 75), ('L', 76), ('M', 77), ('N', 78), ('O', 79), ('P', 80), ('Q', 81), ('R', 82), ('S', 83), ('T', 84), ('U', 85), ('V', 86), ('W', 87), ('X', 88), ('Y', 89), ('Z', 90)]

There are 2 potential issues that I see:

1 - IE has had trouble with position:fixed in the past. If you are using IE7+ with a valid doctype or a non-IE browser this isn't part of the problem

2 - You need to specify a width for the footer if you want the footer object to be centered. Otherwise it defaults to the full width of the page and the auto margin for the left and right get set to 0. If you want the footer bar to take up the width (like the StackOverflow notice bar) and center the text, then you need to add "text-align: center" to your definition.

If you are storing values via any programming language

Here is an example in C#

To store date you have to convert it first and then store it

insert table1 (foodate)
   values (FooDate.ToString("MM/dd/yyyy"));

FooDate is datetime variable which contains your date in your format.

Best solution

open XAMPP control panel,click on config for Apache, then click on Apache(httpd.config).now in the text editor . ctrl+f --> find "Listen 80" and replace it with "Listen 8079" wtihout the quotations :) but now you have to use it like this http://localhost:8079/

P.S, I tried to change port settings for skype , stopping the Web Deployment Agent Service which I could not find in windows 10,cmd--> net stop http, and other methods but nothing worked except this .

We can return like this,

return <React.Fragment />;

Until the end of 2014, a common source of this error was omitting the mandatory sensor parameter from the request, as below. However since then this is no longer required:

The sensor Parameter

The Google Maps API previously required that you include the sensor parameter to indicate whether your application used a sensor to determine the user's location. This parameter is no longer required.

Did you specify the sensor parameter on the request?

"REQUEST_DENIED" indicates that your request was denied, generally because of lack of a sensor parameter.

sensor (required) — Indicates whether or not the geocoding request comes from a device with a location sensor. This value must be either true or false

I know its late to post, but I use the site for my own reference and so I wanted to put an answer here for myself to reference in the future too. I hope you (and others) find it helpful.

Lets pretend a bunch of super Einstein experts designed our database. Our super perfect database has 3 tables, and the following relationships defined between them:

TblA 1:M TblB
TblB 1:M TblC

Notice there is no relationship between TblA and TblC

In most scenarios such a simple database is easy to navigate but in commercial databases it is usually impossible to be able to tell at the design stage all the possible uses and combination of uses for data, tables, and even whole databases, especially as systems get built upon and other systems get integrated or switched around or out. This simple fact has spawned a whole industry built on top of databases called Business Intelligence. But I digress...

In the above case, the structure is so simple to understand that its easy to see you can join from TblA, through to B, and through to C and vice versa to get at what you need. It also very vaguely highlights some of the problems with doing it. Now expand this simple chain to 10 or 20 or 50 relationships long. Now all of a sudden you start to envision a need for exactly your scenario. In simple terms, a join from A to C or vice versa or A to F or B to Z or whatever as our system grows.

There are many ways this can indeed be done. The one mentioned above being the most popular, that is driving through all the links. The major problem is that its very slow. And gets progressively slower the more tables you add to the chain, the more those tables grow, and the further you want to go through it.

Solution 1: Look for a common link. It must be there if you taught of a reason to join A to C. If it is not obvious, create a relationship and then join on it. i.e. To join A through B through C there must be some commonality or your join would either produce zero results or a massive number or results (Cartesian product). If you know this commonality, simply add the needed columns to A and C and link them directly.

The rule for relationships is that they simply must have a reason to exist. Nothing more. If you can find a good reason to link from A to C then do it. But you must ensure your reason is not redundant (i.e. its already handled in some other way).

Now a word of warning. There are some pitfalls. But I don't do a good job of explaining them so I will refer you to my source instead of talking about it here. But remember, this is getting into some heavy stuff, so this video about fan and chasm traps is really only a starting point. You can join without relationships. But I advise watching this video first as this goes beyond what most people learn in college and well into the territory of the BI and SAP guys. These guys, while they can program, their day job is to specialise in exactly this kind of thing. How to get massive amounts of data to talk to each other and make sense.

This video is one of the better videos I have come across on the subject. And it's worth looking over some of his other videos. I learned a lot from him.

You should combine a type pointcut with a method pointcut.

These pointcuts will do the work to find all public methods inside a class marked with an @Monitor annotation:

@Pointcut("within(@org.rejeev.Monitor *)")
public void beanAnnotatedWithMonitor() {}

@Pointcut("execution(public * *(..))")
public void publicMethod() {}

@Pointcut("publicMethod() && beanAnnotatedWithMonitor()")
public void publicMethodInsideAClassMarkedWithAtMonitor() {}

Advice the last pointcut that combines the first two and you're done!

If you're interested, I have written a cheat sheet with @AspectJ style here with a corresponding example document here.

This example works perfectly in Android

In kotlin you can use a lambda expression for this. The Kotlin Array Constructor definition is:

Array(size: Int, init: (Int) -> T)

Which evaluates to:

skillsSummaryDetailLinesArray = Array(linesLen) {
        i: Int -> skillsSummaryDetailLines!!.getString(i)
}

Or:

skillsSummaryDetailLinesArray = Array<String>(linesLen) {
        i: Int -> skillsSummaryDetailLines!!.getString(i)
}

In this example the field definition was:

private var skillsSummaryDetailLinesArray: Array<String>? = null

Hope this helps

The two queries may not be semantically equivalent. If a employee works for more than one department (possible in the enterprise I work for; admittedly, this would imply your table is not fully normalized) then the first query would return duplicate rows whereas the second query would not. To make the queries equivalent in this case, the DISTINCT keyword would have to be added to the SELECT clause, which may have an impact on performance.

Note there is a design rule of thumb that states a table should model an entity/class or a relationship between entities/classes but not both. Therefore, I suggest you create a third table, say OrgChart, to model the relationship between employees and departments.

• LEA means Load Effective Address
• MOV means Load Value

In short, LEA loads a pointer to the item you're addressing whereas MOV loads the actual value at that address.

The purpose of LEA is to allow one to perform a non-trivial address calculation and store the result [for later usage]

LEA ax, [BP+SI+5] ; Compute address of value

MOV ax, [BP+SI+5] ; Load value at that address

Where there are just constants involved, MOV (through the assembler's constant calculations) can sometimes appear to overlap with the simplest cases of usage of LEA. Its useful if you have a multi-part calculation with multiple base addresses etc.

Circa 2019, using jquery, this can be accessed using $('#DOMId').data('typeId') where $('#DOMId') is the jquery selector for your span element.

You can use option:selected to get the chosen option of the select element, then the text() method:

$("select option:selected").text();

Here's an example:

console.log($("select option:selected").text());

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>_x000D_
<select>_x000D_
    <option value="1">Volvo</option>_x000D_
    <option value="2" selected="selected">Saab</option>_x000D_
    <option value="3">Mercedes</option>_x000D_
</select>

You can stablish specific toolbar for div

div::-webkit-scrollbar {
width: 12px;
}

div::-webkit-scrollbar-track {
-webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3);
border-radius: 10px;
}

Have you tried using a view model instead of ViewData? Strongly typed helpers that end with For and take a lambda expression cannot work with weakly typed structures such as ViewData.

Personally I don't use ViewData/ViewBag. I define view models and have my controller actions pass those view models to my views.

For example in your case I would define a view model:

public class MyViewModel
{
    [HiddenInput(DisplayValue = false)]
    public string CRN { get; set; }
}

have my controller action populate this view model:

public ActionResult Index()
{
    var model = new MyViewModel
    {
        CRN = "foo bar"
    };
    return View(model);
}

and then have my strongly typed view simply use an EditorFor helper:

@model MyViewModel
@Html.EditorFor(x => x.CRN)

which would generate me:

<input id="CRN" name="CRN" type="hidden" value="foo bar" />

in the resulting HTML.

IF EXISTS (SELECT 1 FROM Table WHERE FieldValue='') 
BEGIN
   SELECT TableID FROM Table WHERE FieldValue=''
END
ELSE
BEGIN
   INSERT INTO TABLE(FieldValue) VALUES('')
   SELECT SCOPE_IDENTITY() AS TableID
END

See here for more information on IF ELSE

Note: written without a SQL Server install handy to double check this but I think it is correct

Also, I've changed the EXISTS bit to do SELECT 1 rather than SELECT * as you don't care what is returned within an EXISTS, as long as something is I've also changed the SCOPE_IDENTITY() bit to return just the identity assuming that TableID is the identity column

The problem is:

$ docker-compose stop nginx

didn't work (you said it is still running). If you are going to rebuild it anyway, you can try killing it:

$ docker-compose kill nginx

If it still doesn't work, try to stop it with docker directly:

$ docker stop nginx

or delete it

$ docker rm -f nginx

If that still doesn't work, check your version of docker, you might want to upgrade.

It might be a bug, you could check if one matches your system/version. Here are a couple, for ex: https://github.com/docker/docker/issues/10589

https://github.com/docker/docker/issues/12738

As a workaround, you could try to kill the process.

$ ps aux | grep docker 
$ kill 225654 # example process id

Couldn't that just be done by only using a positive button?

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Look at this dialog!")
       .setCancelable(false)
       .setPositiveButton("OK", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
                //do things
           }
       });
AlertDialog alert = builder.create();
alert.show();

Don't use sed, use cut:

grep .... | cut -c 1-N

If you MUST use sed:

grep ... | sed -e 's/^\(.\{12\}\).*/\1/'

If you prefer to use the simplest possible solution to a problem, an alternative to RedirectMatch is, the more basic, Redirect directive.

It does not use pattern matching and so is more explicit and easier for others to understand.

i.e

<IfModule mod_alias.c>

#Repoint old contact page to new contact page:
Redirect 301 /contact.php http://example.com/contact-us.php

</IfModule>

Query strings should be carried over because the docs say:

Additional path information beyond the matched URL-path will be appended to the target URL.

Html.ActionLink generates an <a href=".."></a> tag automatically.

Url.Action generates only an url.

For example:

@Html.ActionLink("link text", "actionName", "controllerName", new { id = "<id>" }, null)

generates:

<a href="/controllerName/actionName/<id>">link text</a>

and

@Url.Action("actionName", "controllerName", new { id = "<id>" }) 

generates:

/controllerName/actionName/<id>

Best plus point which I like is using Url.Action(...)

You are creating anchor tag by your own where you can set your own linked text easily even with some other html tag.

<a href="@Url.Action("actionName", "controllerName", new { id = "<id>" })">

   <img src="<ImageUrl>" style"width:<somewidth>;height:<someheight> />

   @Html.DisplayFor(model => model.<SomeModelField>)
</a>

Just an easy answer for the future which I found easy to use as a starter: Similar to using end='' to avoid a new line, you can use sep='' to avoid the white spaces...for this question here, it would look like this: print('Value is "', value, '"', sep = '')

May it help someone in the future.

    public LightDataTable PagerSelection(int pageNumber, int setsPerPage, Func<LightDataRow, bool> prection = null)
    {
        this.setsPerPage = setsPerPage;
        this.pageNumber = pageNumber > 0 ? pageNumber - 1 : pageNumber;
        if (!ValidatePagerByPageNumber(pageNumber))
            return this;

        var rowList = rows.Cast<LightDataRow>();
        if (prection != null)
            rowList = rows.Where(prection).ToList();

        if (!rowList.Any())
            return new LightDataTable() { TablePrimaryKey = this.tablePrimaryKey };
        //if (rowList.Count() < (pageNumber * setsPerPage))
        //    return new LightDataTable(new LightDataRowCollection(rowList)) { TablePrimaryKey = this.tablePrimaryKey };

        return new LightDataTable(new LightDataRowCollection(rowList.Skip(this.pageNumber * setsPerPage).Take(setsPerPage).ToList())) { TablePrimaryKey = this.tablePrimaryKey };
  }

this is what i did. Normaly you start at 1 but in IList you start with 0. so if you have 152 rows that mean you have 8 paging but in IList you only have 7. hop this can make thing clear for you

    final Calendar newCalendar = Calendar.getInstance();

                    newDate.set(year, monthOfYear, dayOfMonth);
                    activitydate.setText(dateFormatter.format(newDate.getTime()));

make use of the jackson JSON processor

 ObjectMapper mapper = new ObjectMapper();
  Book book = mapper.readValue(request.getInputStream(),Book.class);

... and the uppercase is:

"Awesome String".upcase
=> "AWESOME STRING"

the first step

netstat -vanp tcp | grep 8888

example

tcp4     0      0    127.0.0.1.8888   *.*    LISTEN      131072 131072  76061    0
tcp46    0      0    *.8888           *.*    LISTEN      131072 131072  50523    0

the second step: find your PIDs and kill them

in my case

sudo kill -9 76061 50523

I have also faced the same problem.

After installing m2eclipse plugin, i was not getting any Java compilation errors.

My solution was to enable dependency management by Select Project -> Right Click (to get context menu) -> m2 Maven -> Enable dependency management.

Now i am able to view Java Compilation Errors.

I've created a (German) description how to get it working. You basically need an emulator with at least API level 9 and no Google APIs. Then you'll have to get the APKs from a rooted device:

adb -d pull /data/app/com.android.vending-2.apk
adb -d pull /data/app/com.google.android.gms-2.apk

and install them in the emulator:

adb -e install com.android.vending-2.apk
adb -e install com.google.android.gms-2.apk

You can even run the native Google Maps App, if you have an emulator with at least API level 14 and additionally install com.google.android.apps.maps-1.apk

Have fun.

You might try using a library like redux-saga. It allows for a very clean way to sequence async functions, fire off actions, use delays and more. It is very powerful!

You can have one alternative of using placeholders as:

@Query("Select c from Registration c where c.place LIKE  %?1%")
List<Registration> findPlaceContainingKeywordAnywhere(String place);

This is not exactly what you asked for but, with this method I can Iterate throught componentsList in my other files and use function such as componentsList.map(...) which I find pretty usefull !

import StepOne from './StepOne';
import StepTwo from './StepTwo';
import StepThree from './StepThree';
import StepFour from './StepFour';
import StepFive from './StepFive';
import StepSix from './StepSix';
import StepSeven from './StepSeven';
import StepEight from './StepEight';

const componentsList= () => [
  { component: StepOne(), key: 'step1' },
  { component: StepTwo(), key: 'step2' },
  { component: StepThree(), key: 'step3' },
  { component: StepFour(), key: 'step4' },
  { component: StepFive(), key: 'step5' },
  { component: StepSix(), key: 'step6' },
  { component: StepSeven(), key: 'step7' },
  { component: StepEight(), key: 'step8' }
];

export default componentsList;

It might be too late to answer this in 2019. but I tried all the answers and none worked for me. So I solved it simply this way:

@Html.EditorFor(m => m.SellDateForInstallment, "{0:dd/MM/yyyy}", 
               new {htmlAttributes = new { @class = "form-control", @type = "date" } })

EditorFor is what worked for me.

Note that SellDateForInstallment is a Nullable datetime object.

public DateTime? SellDateForInstallment { get; set; } // Model property

As per latest api docs:

$(document).ready(function() {
    $('#example').dataTable({
        "order": []
    });
});

More Info

For people having a startTime (like 12h:30:30) and a duration (value in minutes like 120), you can guess the endTime like so:

const startTime = '12:30:00';
const durationInMinutes = '120';

const endTime = moment(startTime, 'HH:mm:ss').add(durationInMinutes, 'minutes').format('HH:mm');

// endTime is equal to "14:30"

Remove the comma

receipt int(10),

And also AUTO INCREMENT should be a KEY

double datatype also requires the precision of decimal places so right syntax is double(10,2)

Swift 4, Autolayout version

func showActivityIndicator(on parentView: UIView) {
    let activityIndicator = UIActivityIndicatorView(activityIndicatorStyle: .gray)
    activityIndicator.startAnimating()
    activityIndicator.translatesAutoresizingMaskIntoConstraints = false

    parentView.addSubview(activityIndicator)

    NSLayoutConstraint.activate([
        activityIndicator.centerXAnchor.constraint(equalTo: parentView.centerXAnchor),
        activityIndicator.centerYAnchor.constraint(equalTo: parentView.centerYAnchor),
    ])
}

Never trust user data.

function clean_input($data) {
  $data = trim($data);
  $data = stripslashes($data);
  $data = htmlspecialchars($data);
  return $data;
}

The trim() function removes whitespace and other predefined characters from both sides of a string.

The stripslashes() function removes backslashes

The htmlspecialchars() function converts some predefined characters to HTML entities.

The predefined characters are:

& (ampersand) becomes &
" (double quote) becomes "
' (single quote) becomes '
< (less than) becomes &lt;
> (greater than) becomes &gt;

This is an old thread but I was surprised nobody mentioned grep. The -A option allows specifying a number of lines to print after a search match and the -B option includes lines before a match. The following command would output 10 lines before and 10 lines after occurrences of "my search string" in the file "mylogfile.log":

grep -A 10 -B 10 "my search string" mylogfile.log

If there are multiple matches within a large file the output can rapidly get unwieldy. Two helpful options are -n which tells grep to include line numbers and --color which highlights the matched text in the output.

If there is more than file to be searched grep allows multiple files to be listed separated by spaces. Wildcards can also be used. Putting it all together:

grep -A 10 -B 10 -n --color "my search string" *.log someOtherFile.txt

You have to use RegExp:

str.match(new RegExp(pattern1+'|'+pattern2, 'gi'));

When I'm concatenating strings, all slashes are gone.

If you have a backslash in your pattern to escape a special regex character, (like \(), you have to use two backslashes in the string (because \ is the escape character in a string): new RegExp('\\(') would be the same as /\(/.

So your patterns have to become:

var pattern1 = ':\\(|:=\\(|:-\\(';
var pattern2 = ':\\(|:=\\(|:-\\(|:\\(|:=\\(|:-\\(';

Determine if a cell is within a range using VBA in Microsoft Excel:

From the linked site (maintaining credit to original submitter):

VBA macro tip contributed by Erlandsen Data Consulting offering Microsoft Excel Application development, template customization, support and training solutions

Function InRange(Range1 As Range, Range2 As Range) As Boolean
    ' returns True if Range1 is within Range2
    InRange = Not (Application.Intersect(Range1, Range2) Is Nothing)
End Function


Sub TestInRange()
    If InRange(ActiveCell, Range("A1:D100")) Then
        ' code to handle that the active cell is within the right range
        MsgBox "Active Cell In Range!"
    Else
        ' code to handle that the active cell is not within the right range
        MsgBox "Active Cell NOT In Range!"
    End If
End Sub

Had same issue in win64bit and JVM 64bit

Was solved by uploading dll to system32

In your case you can do that without using push at all:

var myArray = [
    [1,1,1,1,1],
    [1,1,1,1,1],
    [1,1,1,1,1]
]

var newRows = 8;
var newCols = 7;

var item;

for (var i = 0; i < newRows; i++) {
    item = myArray[i] || (myArray[i] = []);

    for (var k = item.length; k < newCols; k++)
        item[k] = 0;    
}

If you set

-Djava.io.tmpdir=C:\temp

please use this

var uri = "ws://localhost:5000/ws";
var socket = new WebSocket(uri);
socket.onclose = function (e){
    console.log(connection closed);
};
window.addEventListener("unload", function () {
    if(socket.readyState == WebSocket.OPEN)
        socket.close();
});

Close browser doesn't trigger websocket close event. You must call socket.close() manually.

Unfortunately it's not just about reading uncommitted data. In the background you may end up reading pages twice (in the case of a page split), or you may miss the pages altogether. So your results may be grossly skewed.

Check out Itzik Ben-Gan's article. Here's an excerpt:

" With the NOLOCK hint (or setting the isolation level of the session to READ UNCOMMITTED) you tell SQL Server that you don't expect consistency, so there are no guarantees. Bear in mind though that "inconsistent data" does not only mean that you might see uncommitted changes that were later rolled back, or data changes in an intermediate state of the transaction. It also means that in a simple query that scans all table/index data SQL Server may lose the scan position, or you might end up getting the same row twice. "

.live() is used if elements are being added after the initial page load. Say you have a button which gets added by an AJAX call after the page gets loaded. This new button will not be accessible using .click(), so you'll have to use .live('click')

The other features of CodeLens like: Show Bugs, Show Test Status, etc (other than Show Reference) might be useful.

However, if the only way to disable Show References is to disable CodeLens altogether.

Then, I guess I could do just that.

Furthermore, I would do like I always have, 'right-click on a member and choose Find all References or Ctrl+K, R'

If I wanted to know what references the member -- I too like not having any extra information crammed into my code, like extra white-space.

In short, uncheck Codelens...

You can use below query to update or create comment on already created table.

SYNTAX:

COMMENT ON COLUMN TableName.ColumnName IS 'comment text';

Example:

COMMENT ON COLUMN TAB_SAMBANGI.MY_COLUMN IS 'This is a comment on my column...';

I was facing with this problem some time ago and I found java.util.LinkedList is best for my case. It has several methods, with different namings, but they're doing what is needed:

push()    -> LinkedList.addLast(); // Or just LinkedList.add();
pop()     -> LinkedList.pollLast();
shift()   -> LinkedList.pollFirst();
unshift() -> LinkedList.addFirst();

I would add the CSS property of float left as seen below. That gets rid of the extra space.

ul li {
    float:left;
}

You can use a very good online tool for it. Here is the link dreampuf.github.io Just replace the code inside editer with your code.

Note: Parent constructors are not called implicitly if the child class defines a constructor. In order to run a parent constructor, a call to parent::__construct() within the child constructor is required. If the child does not define a constructor then it may be inherited from the parent class just like a normal class method (if it was not declared as private).

use labelpad parameter:

pl.xlabel("...", labelpad=20)

or set it after:

ax.xaxis.labelpad = 20

Here is answer to your question.

By default maven looks in ../pom.xml for relativePath. Use empty <relativePath/> tag instead.

First create a DataGridTemplateColumn to contain the button:

<DataGridTemplateColumn>
  <DataGridTemplateColumn.CellTemplate> 
    <DataTemplate> 
      <Button Click="ShowHideDetails">Details</Button> 
    </DataTemplate> 
  </DataGridTemplateColumn.CellTemplate> 
</DataGridTemplateColumn>

When the button is clicked, update the containing DataGridRow's DetailsVisibility:

void ShowHideDetails(object sender, RoutedEventArgs e)
{
    for (var vis = sender as Visual; vis != null; vis = VisualTreeHelper.GetParent(vis) as Visual)
    if (vis is DataGridRow)
    {
        var row = (DataGridRow)vis;
        row.DetailsVisibility = 
        row.DetailsVisibility == Visibility.Visible ? Visibility.Collapsed : Visibility.Visible;
        break;
    }
}

Fix: Unlock your device before running it.

Hi Guys: Think I may have a fix for this:

Sounds ridiculous but try unlocking your Virtual Device; i.e. use your mouse to swipe and open. Your app should then work!!

Nothing in the example says that the "classes implementing the same interface". MovieCatalog is a type and CustomerPreferenceDao is another type. Spring can easily tell them apart.

In Spring 2.x, wiring of beans mostly happened via bean IDs or names. This is still supported by Spring 3.x but often, you will have one instance of a bean with a certain type - most services are singletons. Creating names for those is tedious. So Spring started to support "autowire by type".

What the examples show is various ways that you can use to inject beans into fields, methods and constructors.

The XML already contains all the information that Spring needs since you have to specify the fully qualified class name in each bean. You need to be a bit careful with interfaces, though:

This autowiring will fail:

 @Autowired
 public void prepare( Interface1 bean1, Interface1 bean2 ) { ... }

Since Java doesn't keep the parameter names in the byte code, Spring can't distinguish between the two beans anymore. The fix is to use @Qualifier:

 @Autowired
 public void prepare( @Qualifier("bean1") Interface1 bean1,
     @Qualifier("bean2")  Interface1 bean2 ) { ... }

I ran into this problem after a fresh install of Android Studio (in GNU/Linux). I also used the installation wizard for Android SDK, and the Build Tools 28.0.3 were installed, although Android Studio tried to use 28.0.2 instead.

But the problem was not the build tools version but the license. I had not accepted the Android SDK license (the wizard does not ask for it), and Android Studio refused to use the build tools; the error message just is wrong.

In order to solve the problem, I manually accepted the license. In a terminal, I launched $ANDROID_SDK/tools/bin/sdkmanager --licenses and answered "Yes" for the SDK license. The other ones can be refused.

We actually had these merged together originally, i.e. there was a "filter"-like method that accepted *args and **kwargs, where you could pass a SQL expression or keyword arguments (or both). I actually find that a lot more convenient, but people were always confused by it, since they're usually still getting over the difference between column == expression and keyword = expression. So we split them up.

This will work.

def check(arr):
    if np.all(arr == 0):
        return True
    return False

I use numpy.fromiter to invert a 8-greyscale bitmap, yet no signs of side-effects

import Image
import numpy as np

im = Image.load('foo.jpg')
im = im.convert('L')

arr = np.fromiter(iter(im.getdata()), np.uint8)
arr.resize(im.height, im.width)

arr ^= 0xFF  # invert
inverted_im = Image.fromarray(arr, mode='L')
inverted_im.show()

Sometimes two classes may have some parameter names in common. In that case, you can't pop the key-value pairs off of **kwargs or remove them from *args. Instead, you can define a Base class which unlike object, absorbs/ignores arguments:

class Base(object):
    def __init__(self, *args, **kwargs): pass

class A(Base):
    def __init__(self, *args, **kwargs):
        print "A"
        super(A, self).__init__(*args, **kwargs)

class B(Base):
    def __init__(self, *args, **kwargs):
        print "B"
        super(B, self).__init__(*args, **kwargs)

class C(A):
    def __init__(self, arg, *args, **kwargs):
        print "C","arg=",arg
        super(C, self).__init__(arg, *args, **kwargs)

class D(B):
    def __init__(self, arg, *args, **kwargs):
        print "D", "arg=",arg
        super(D, self).__init__(arg, *args, **kwargs)

class E(C,D):
    def __init__(self, arg, *args, **kwargs):
        print "E", "arg=",arg
        super(E, self).__init__(arg, *args, **kwargs)

print "MRO:", [x.__name__ for x in E.__mro__]
E(10)

yields

MRO: ['E', 'C', 'A', 'D', 'B', 'Base', 'object']
E arg= 10
C arg= 10
A
D arg= 10
B

Note that for this to work, Base must be the penultimate class in the MRO.

I see this topic, but in my case I was looking for a way to improve the format. Using UFormat and adding -1 day

(get-date (get-date).addDays(-1) -UFormat "%Y%m%d-%H%M")

Error in file(file, "rt") :

I just faced the same error and resolved by removing spacing in address using paste0 instead of paste

filepath=paste0(directory,"/",filename[1],sep="")

Instead of relying only on <c:out />, an antixss library should also be used, which will not only encode but also sanitize malicious script in input. One of the best library available is OWASP Antisamy, it's highly flexible and can be configured(using xml policy files) as per requirement.

For e.g. if an application supports only text input then most generic policy file provided by OWASP can be used which sanitizes and removes most of the html tags. Similarly if application support html editors(such as tinymce) which need all kind of html tags, a more flexible policy can be use such as ebay policy file

For SQL Server 2008, the best and index friendly way is

DELETE from Table WHERE Date > CAST(GETDATE() as DATE);

For prior SQL Server versions, date maths will work faster than a convert to varchar. Even converting to varchar can give you the wrong result, because of regional settings.

DELETE from Table WHERE Date > DATEDIFF(d, 0, GETDATE());

_{Note: it is unnecessary to wrap the DATEDIFF with another DATEADD}

You probably don't want to do this:

#include "client.cpp"

A *.cpp file will have been compiled by the compiler as part of your build. By including it in other files, it will be compiled again (and again!) in every file in which you include it.

Now here's the thing: You are guarding it with #ifndef SOCKET_CLIENT_CLASS, however, each file that has #include "client.cpp" is built independently and as such will find SOCKET_CLIENT_CLASS not yet defined. Therefore it's contents will be included, not #ifdef'd out.

If it contains any definitions at all (rather than just declarations) then these definitions will be repeated in every file where it's included.

For those who need the same feature in IE 8, this is how I solved the problem:

  var myImage = $('<img/>');

               myImage.attr('width', 300);
               myImage.attr('height', 300);
               myImage.attr('class', "groupMediaPhoto");
               myImage.attr('src', photoUrl);

I could not force IE8 to use object in constructor.

If you have a "Win32 project" + defined a WinMain and your SubSystem linker setting is set to WINDOWS you can still get this linker error in case somebody set the "Additional Options" in the linker settings to "/SUBSYSTEM:CONSOLE" (looks like this additional setting is preferred over the actual SubSystem setting.

Finally I could successfully compile a program with C++ connector in Ubuntu 12.04 I have installed the connector using this command

'apt-get install libmysqlcppconn-dev'

Initially I faced the same problem with "undefined reference to `get_driver_instance' " to solve this I declare my driver instance variable of MySQL_Driver type. For ready reference this type is defined in mysql_driver.h file. Here is the code snippet I used in my program.

sql::mysql::MySQL_Driver *driver;
try {     
    driver = sql::mysql::get_driver_instance();
}

and I compiled the program with -l mysqlcppconn linker option

and don't forget to include this header

#include "mysql_driver.h" 

After hours of googling, reading, uninstalling, facepalming! It turned out that a chrome extension for VPN was handling the proxy settings for Chrome!

Betternet to be more specific!

Disabling it, solved my problem.

To make sure it is not the problem, check the proxy settings for Chrome itself. For me it showed me a message, says : Betternet is handling the proxy settings.

One thing we should note: the jdk should be installed on C: drive.

I had JDK installed on my D: drive like this:

D:\Program Files\Java\jdk1.8.0_101

And it would still give me the same error. For some reason Java should be installed on C: drive.

Using an empty string is perfectly fine and actually much safer than simply using $_SERVER['PHP_SELF'].

When using $_SERVER['PHP_SELF'] it is very easy to inject malicious data by simply appending /<script>... after the whatever.php part of the URL so you should not use this method and stop using any PHP tutorial that suggests it.

You can use the UIScrollView's setContentOffset:animated: function to scroll to any part of the content view. Here's some code that would scroll to the bottom, assuming your scrollView is self.scrollView:

Objective-C:

CGPoint bottomOffset = CGPointMake(0, self.scrollView.contentSize.height - self.scrollView.bounds.size.height + self.scrollView.contentInset.bottom);
[self.scrollView setContentOffset:bottomOffset animated:YES];

Swift:

let bottomOffset = CGPoint(x: 0, y: scrollView.contentSize.height - scrollView.bounds.height + scrollView.contentInset.bottom)
scrollView.setContentOffset(bottomOffset, animated: true)

Hope that helps!

In your case, I believe the update will be faster.

Remember indexes!

You have defined a primary key, it will likely automatically become a clustered index (at least SQL Server does so). A cluster index means the records are physically laid on the disk according to the index. DELETE operation itself won't cause much trouble, even after one record goes away, the index stays correct. But when you INSERT a new record, the DB engine will have to put this record in the correct location which under circumstances will cause some "reshuffling" of the old records to "make place" for a new one. There where it will slow down the operation.

An index (especially clustered) works best if the values are ever increasing, so the new records just get appended to the tail. Maybe you can add an extra INT IDENTITY column to become a clustered index, this will simplify insert operations.

.NET 3.5 and newer have a new public type, System.Data.Linq.Binary that encapsulates byte[]. It implements IEquatable<Binary> that (in effect) compares two byte arrays. Note that System.Data.Linq.Binary also has implicit conversion operator from byte[].

MSDN documentation:System.Data.Linq.Binary

Reflector decompile of the Equals method:

private bool EqualsTo(Binary binary)
{
    if (this != binary)
    {
        if (binary == null)
        {
            return false;
        }
        if (this.bytes.Length != binary.bytes.Length)
        {
            return false;
        }
        if (this.hashCode != binary.hashCode)
        {
            return false;
        }
        int index = 0;
        int length = this.bytes.Length;
        while (index < length)
        {
            if (this.bytes[index] != binary.bytes[index])
            {
                return false;
            }
            index++;
        }
    }
    return true;
}

Interesting twist is that they only proceed to byte-by-byte comparison loop if hashes of the two Binary objects are the same. This, however, comes at the cost of computing the hash in constructor of Binary objects (by traversing the array with for loop :-) ).

The above implementation means that in the worst case you may have to traverse the arrays three times: first to compute hash of array1, then to compute hash of array2 and finally (because this is the worst case scenario, lengths and hashes equal) to compare bytes in array1 with bytes in array 2.

Overall, even though System.Data.Linq.Binary is built into BCL, I don't think it is the fastest way to compare two byte arrays :-|.

This is what I did in my makefile based on others solutions. Note not only does this give your code a revision number, it also appends the hash which allows you to recreate the release.

# Set the source control revision similar to subversion to use in 'c'
# files as a define.
# You must build in the master branch otherwise the build branch will
# be prepended to the revision and/or "dirty" appended. This is to
# clearly ID developer builds.
REPO_REVISION_:=$(shell git rev-list HEAD --count)
BUILD_BRANCH:=$(shell git rev-parse --abbrev-ref HEAD)
BUILD_REV_ID:=$(shell git rev-parse HEAD)
BUILD_REV_ID_SHORT:=$(shell git describe --long --tags --dirty --always)
ifeq ($(BUILD_BRANCH), master)
REPO_REVISION:=$(REPO_REVISION_)_g$(BUILD_REV_ID_SHORT)
else
REPO_REVISION:=$(BUILD_BRANCH)_$(REPO_REVISION_)_r$(BUILD_REV_ID_SHORT)
endif
export REPO_REVISION
export BUILD_BRANCH
export BUILD_REV_ID

My solution requires the array be formatted differently than provided in the question:

<?
    $data = array(
        array( 'row_1_col_1', 'row_1_col_2', 'row_1_col_3' ),
        array( 'row_2_col_1', 'row_2_col_2', 'row_2_col_3' ),
        array( 'row_3_col_1', 'row_3_col_2', 'row_3_col_3' ),
    );
?>

We define our function:

<?
    function outputCSV($data) {
        $outputBuffer = fopen("php://output", 'w');
        foreach($data as $val) {
            fputcsv($outputBuffer, $val);
        }
        fclose($outputBuffer);
    }
?>

Then we output our data as a CSV:

<?
    $filename = "example";

    header("Content-type: text/csv");
    header("Content-Disposition: attachment; filename={$filename}.csv");
    header("Pragma: no-cache");
    header("Expires: 0");

    outputCSV($data);
?>

I have used this with several projects, and it works well. I should note that the outputCSV code is more clever than I am, so I am sure I am not the original author. Unfortunately I have lost track of where I got it, so I can't give the credit to whom it is due.

OP wants mmddyy and a plain convert will not work for that:

select convert(datetime,'12312009')

Msg 242, Level 16, State 3, Line 1 
The conversion of a char data type to a datetime data type resulted in 
an out-of-range datetime value

so try this:

DECLARE @Date char(8)
set @Date='12312009'
SELECT CONVERT(datetime,RIGHT(@Date,4)+LEFT(@Date,2)+SUBSTRING(@Date,3,2))

OUTPUT:

-----------------------
2009-12-31 00:00:00.000

public static string XmlSerializeToString(this object objectInstance)
{
    var serializer = new XmlSerializer(objectInstance.GetType());
    var sb = new StringBuilder();

    using (TextWriter writer = new StringWriter(sb))
    {
        serializer.Serialize(writer, objectInstance);
    }

    return sb.ToString();
}

public static T XmlDeserializeFromString<T>(this string objectData)
{
    return (T)XmlDeserializeFromString(objectData, typeof(T));
}

public static object XmlDeserializeFromString(this string objectData, Type type)
{
    var serializer = new XmlSerializer(type);
    object result;

    using (TextReader reader = new StringReader(objectData))
    {
        result = serializer.Deserialize(reader);
    }

    return result;
}

To use it:

//Make XML
var settings = new ObjectCustomerSettings();
var xmlString = settings.XmlSerializeToString();

//Make Object
var settings = xmlString.XmlDeserializeFromString<ObjectCustomerSettings>(); 

For finding value use below

if let a = companies["AAPL"] {
   // a is the value
}

For traversing through the dictionary

for (key, value) in companies {
    print(key,"---", value)
}

Finally for searching key by value you firstly add the extension

extension Dictionary where Value: Equatable {
    func findKey(forValue val: Value) -> Key? {
        return first(where: { $1 == val })?.key
    }
}

Then just call

companies.findKey(val : "Apple Inc")

I wrote a directive which lets you limit the areas where a click has effect. It could be used for certain scenarios like this one, so instead of having to deal with the click on a case by case basis you can just say "clicks won't come out of this element".

You would use it like this:

<table>
  <tr ng-repeat="user in users" ng-click="showUser(user)">
    <td>{{user.firstname}}</td>
    <td>{{user.lastname}}</td>
    <td isolate-click>
      <button class="btn" ng-click="deleteUser(user.id, $index);">
        Delete
      </button>
    </td>              
  </tr>
</table>

Keep in mind that this would prevent all clicks on the last cell, not just the button. If that's not what you want you may want to wrap the button like this:

<span isolate-click>
    <button class="btn" ng-click="deleteUser(user.id, $index);">
        Delete
    </button>
</span>

Here is the directive's code:

angular.module('awesome', []).directive('isolateClick', function() {
    return {
        link: function(scope, elem) {
            elem.on('click', function(e){
                e.stopPropagation();
            });
        }
   };
});

This is a good catch by Joe. The code example above has two problems - one - the response object isn't an instance of Bitmap (when my URL references a jpg, like http:\website.com\image.jpg, its a

org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnectionImpl$LimitedInputStream).

Second, as Joe points out, no caching occurs without a response cache being configured. Android developers are left to roll their own cache. Here's an example for doing so, but it only caches in memory, which really isn't the full solution.

http://codebycoffee.com/2010/06/29/using-responsecache-in-an-android-app/

The URLConnection caching API is described here:

http://download.oracle.com/javase/6/docs/technotes/guides/net/http-cache.html

I still think this is an OK solution to go this route - but you still have to write a cache. Sounds like fun, but I'd rather write features.

You will need to use ProcessStartInfo with RedirectStandardOutput enabled - then you can read the output stream. You might find it easier to use ">" to redirect the output to a file (via the OS), and then simply read the file.

[edit: like what Ray did: +1]

In Python 3.x and 2.x you can use use list to force a copy of the keys to be made:

for i in list(d):

In Python 2.x calling keys made a copy of the keys that you could iterate over while modifying the dict:

for i in d.keys():

But note that in Python 3.x this second method doesn't help with your error because keys returns an a view object instead of copynig the keys into a list.

A NATURAL join is just short syntax for a specific INNER join -- or "equi-join" -- and, once the syntax is unwrapped, both represent the same Relational Algebra operation. It's not a "different kind" of join, as with the case of OUTER (LEFT/RIGHT) or CROSS joins.

See the equi-join section on Wikipedia:

A natural join offers a further specialization of equi-joins. The join predicate arises implicitly by comparing all columns in both tables that have the same column-names in the joined tables. The resulting joined table contains only one column for each pair of equally-named columns.

Most experts agree that NATURAL JOINs are dangerous and therefore strongly discourage their use. The danger comes from inadvertently adding a new column, named the same as another column ...

That is, all NATURAL joins may be written as INNER joins (but the converse is not true). To do so, just create the predicate explicitly -- e.g. USING or ON -- and, as Jonathan Leffler pointed out, select the desired result-set columns to avoid "duplicates" if desired.

Happy coding.

(The NATURAL keyword can also be applied to LEFT and RIGHT joins, and the same applies. A NATURAL LEFT/RIGHT join is just a short syntax for a specific LEFT/RIGHT join.)

Change the date range to "General" format and save the workbook once, and change them back to date format (eg, numberformat = "d/m/yyyy") before save & close the book. savechanges parameter is true.

Add an :order parameter to the query

Use sys.getsizeof to get the size of an object, in bytes.

>>> from sys import getsizeof
>>> a = 42
>>> getsizeof(a)
12
>>> a = 2**1000
>>> getsizeof(a)
146
>>>

Note that the size and layout of an object is purely implementation-specific. CPython, for example, may use totally different internal data structures than IronPython. So the size of an object may vary from implementation to implementation.

They changed the packaging for psycopg2. Installing the binary version fixed this issue for me. The above answers still hold up if you want to compile the binary yourself.

See http://initd.org/psycopg/docs/news.html#what-s-new-in-psycopg-2-8.

Binary packages no longer installed by default. The ‘psycopg2-binary’ package must be used explicitly.

And http://initd.org/psycopg/docs/install.html#binary-install-from-pypi

So if you don't need to compile your own binary, use:

pip install psycopg2-binary

  override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)

    let tapGesture = UITapGestureRecognizer(target: self, action: "hideNavBarOntap")let tapGesture = UITapGestureRecognizer(target: self, action: "hideNavBarOntap")
    tapGesture.delegate = self
    self.view.addGestureRecognizer(tapGesture)

then write

func hideNavBarOntap() {
    if(self.navigationController?.navigationBar.hidden == false) {
        self.navigationController?.setNavigationBarHidden(true, animated: true) // hide nav bar is not hidden
    } else if(self.navigationController?.navigationBar.hidden == true) {
        self.navigationController?.setNavigationBarHidden(false, animated: true) // show nav bar
    }
}

To find master page controls on Child page

Label lbl_UserName = this.Master.FindControl("lbl_UserName") as Label;                    
lbl_UserName.Text = txtUsr.Text;

You can try this methods

window.open(location, '_self').close();

Resolve the route to a URL and navigate the window with Javascript.

        let r = this.$router.resolve({_x000D_
        name: this.$route.name, // put your route information in_x000D_
        params: this.$route.params, // put your route information in_x000D_
        query: this.$route.query // put your route information in_x000D_
      });_x000D_
      window.location.assign(r.href)

This method replaces the URL and causes the page to do a full request (refresh) rather than relying on Vue.router. $router.go does not work the same for me even though it is theoretically supposed to.

In python 3 things are a little different, but way simpler and less error prone. It's a good idea to tell the CSV your file should be opened with utf8 encoding, as it makes that data more portable to others (assuming you aren't using a more restrictive encoding, like latin1)

import csv
toCSV = [{'name':'bob','age':25,'weight':200},
         {'name':'jim','age':31,'weight':180}]
with open('people.csv', 'w', encoding='utf8', newline='') as output_file:
    fc = csv.DictWriter(output_file, 
                        fieldnames=toCSV[0].keys(),

                       )
    fc.writeheader()
    fc.writerows(toCSV)

• Note that csv in python 3 needs the newline='' parameter, otherwise you get blank lines in your CSV when opening in excel/opencalc.

Alternatively: I prefer use to the csv handler in the pandas module. I find it is more tolerant of encoding issues, and pandas will automatically convert string numbers in CSVs into the correct type (int,float,etc) when loading the file.

import pandas
dataframe = pandas.read_csv(filepath)
list_of_dictionaries = dataframe.to_dict('records')
dataframe.to_csv(filepath)

Note:

• pandas will take care of opening the file for you if you give it a path, and will default to utf8 in python3, and figure out headers too.
• a dataframe is not the same structure as what CSV gives you, so you add one line upon loading to get the same thing: dataframe.to_dict('records')
• pandas also makes it much easier to control the order of columns in your csv file. By default, they're alphabetical, but you can specify the column order. With vanilla csv module, you need to feed it an OrderedDict or they'll appear in a random order (if working in python < 3.5). See: Preserving column order in Python Pandas DataFrame for more.

You can do this with a mix of Java and Scala libraries. You will have full control over the character encoding. But unfortunately, the file handles will not be closed properly.

I found that default API 23 x86_64 emulator is rooted by default.

as other answers here have mentioned, you probably want to either require a local json file that you know is safe and present, like a configuration file:

var objectFromRequire = require('path/to/my/config.json'); 

or to use the global JSON object to parse a string value into an object:

var stringContainingJson = '\"json that is obtained from somewhere\"';
var objectFromParse = JSON.parse(stringContainingJson);

note that when you require a file the content of that file is evaluated, which introduces a security risk in case it's not a json file but a js file.

here, i've published a demo where you can see both methods and play with them online (the parsing example is in app.js file - then click on the run button and see the result in the terminal): http://staging1.codefresh.io/labs/api/env/json-parse-example

you can modify the code and see the impact...

df2 <- data.frame(apply(df1, 2, function(x) as.numeric(as.character(x))))

  public static void copyFile(File oldLocation, File newLocation) throws IOException {
        if ( oldLocation.exists( )) {
            BufferedInputStream  reader = new BufferedInputStream( new FileInputStream(oldLocation) );
            BufferedOutputStream  writer = new BufferedOutputStream( new FileOutputStream(newLocation, false));
            try {
                byte[]  buff = new byte[8192];
                int numChars;
                while ( (numChars = reader.read(  buff, 0, buff.length ) ) != -1) {
                    writer.write( buff, 0, numChars );
                }
            } catch( IOException ex ) {
                throw new IOException("IOException when transferring " + oldLocation.getPath() + " to " + newLocation.getPath());
            } finally {
                try {
                    if ( reader != null ){                      
                        writer.close();
                        reader.close();
                    }
                } catch( IOException ex ){
                    Log.e(TAG, "Error closing files when transferring " + oldLocation.getPath() + " to " + newLocation.getPath() ); 
                }
            }
        } else {
            throw new IOException("Old location does not exist when transferring " + oldLocation.getPath() + " to " + newLocation.getPath() );
        }
    }  

Just complementing: It's kind of obvious, but you can use static imports to give you a hand, like this:

import static javax.swing.JOptionPane.*;

public class SimpleDialog(){
    public static void main(String argv[]) {
        showMessageDialog(null, "Message", "Title", ERROR_MESSAGE);
    }
}

I could solve the issue simply by replacing the JPA api jar file which is located jboss7/modules/javax/persistence/api/main with 'hibernate-jpa-2.1-api'. also with updating module.xml in the directory.

public class Shift {
 public static void main(String[] args) {
  Byte b = Byte.parseByte("00101011",2);
  System.out.println(b);
  byte val = b.byteValue();
  Byte shifted = new Byte((byte) (val >> 2));
  System.out.println(shifted);

  // often overloked  are the methods of Integer

  int i = Integer.parseInt("00101011",2);
  System.out.println( Integer.toBinaryString(i));
  i >>= 2;
  System.out.println( Integer.toBinaryString(i));
 }
}

Output:

43
10
101011
1010

The best solution is to keep multiple Views in a Single View / View Group and then keep that one view in the SrcollView. ie.

Format -

<ScrollView> 
  <Another View>
       <RecyclerView>
       <TextView>
       <And Other Views>
  </Another View>
</ScrollView>

Eg.

<ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TextView           
              android:text="any text"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"/>


        <TextView           
              android:text="any text"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"/>
 </ScrollView>

Another Eg. of ScrollView with multiple Views

<ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1">
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:orientation="vertical"
            android:layout_weight="1">

            <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/imageView"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="#FFFFFF"
                />

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:paddingHorizontal="10dp"

JRockit Mission Control is becoming Java Mission Control and will be dedicated exclusively to Hotspot. If you are an Oracle customer, you can download the 5.x versions of Java Mission Control from MOS (My Oracle Support). Java Mission Control will eventually be released together with the Oracle JDK. The reason it is not yet generally available is that there are some serious limitations, especially when using the Flight Recorder. However, if you are only interested in using the JMX console, you should be golden!

Decimal datatype

• Unlike hardware based binary floating point, the decimal module has a user alterable precision (defaulting to 28 places) which can be as large as needed for a given problem.

If you are pressed by performance issuses, have a look at GMPY

This way I solved my problem. Hope it helps others. In my case I created a class, a field, their getter & setter and then provide the object instead of string.

Use this

public static class EncryptedData {
    private String encryptedData;

    public String getEncryptedData() {
        return encryptedData;
    }

    public void setEncryptedData(String encryptedData) {
        this.encryptedData = encryptedData;
    }
}

@PutMapping(value = MY_IP_ADDRESS)
public ResponseEntity<RestResponse> updateMyIpAddress(@RequestBody final EncryptedData encryptedData) {
    try {
        Path path = Paths.get(PUBLIC_KEY);
        byte[] bytes = Files.readAllBytes(path);
        PKCS8EncodedKeySpec ks = new PKCS8EncodedKeySpec(base64.decode(bytes));
        PrivateKey privateKey = KeyFactory.getInstance(CRYPTO_ALGO_RSA).generatePrivate(ks);

        Cipher cipher = Cipher.getInstance(CRYPTO_ALGO_RSA);
        cipher.init(Cipher.PRIVATE_KEY, privateKey);
        String decryptedData = new String(cipher.doFinal(encryptedData.getEncryptedData().getBytes()));
        String[] dataArray = decryptedData.split("|");


        Method updateIp = Class.forName("com.cuanet.client.helper").getMethod("methodName", String.class,String.class);
        updateIp.invoke(null, dataArray[0], dataArray[1]);

    } catch (Exception e) {
        LOG.error("Unable to update ip address for encrypted data: "+encryptedData, e);
    }

    return null;

Instead of this

@PutMapping(value = MY_IP_ADDRESS)
public ResponseEntity<RestResponse> updateMyIpAddress(@RequestBody final EncryptedData encryptedData) {
    try {
        Path path = Paths.get(PUBLIC_KEY);
        byte[] bytes = Files.readAllBytes(path);
        PKCS8EncodedKeySpec ks = new PKCS8EncodedKeySpec(base64.decode(bytes));
        PrivateKey privateKey = KeyFactory.getInstance(CRYPTO_ALGO_RSA).generatePrivate(ks);

        Cipher cipher = Cipher.getInstance(CRYPTO_ALGO_RSA);
        cipher.init(Cipher.PRIVATE_KEY, privateKey);
        String decryptedData = new String(cipher.doFinal(encryptedData.getBytes()));
        String[] dataArray = decryptedData.split("|");


        Method updateIp = Class.forName("com.cuanet.client.helper").getMethod("methodName", String.class,String.class);
        updateIp.invoke(null, dataArray[0], dataArray[1]);

    } catch (Exception e) {
        LOG.error("Unable to update ip address for encrypted data: "+encryptedData, e);
    }

    return null;
}

Use this:

In [105]: a
Out[105]: 
array([[15, 30, 88, 31, 33],
       [53, 38, 54, 47, 56],
       [67,  2, 74, 10, 16],
       [86, 33, 15, 51, 32],
       [32, 47, 76, 15, 81]], dtype=int32)

In [106]: float32(a)
Out[106]: 
array([[ 15.,  30.,  88.,  31.,  33.],
       [ 53.,  38.,  54.,  47.,  56.],
       [ 67.,   2.,  74.,  10.,  16.],
       [ 86.,  33.,  15.,  51.,  32.],
       [ 32.,  47.,  76.,  15.,  81.]], dtype=float32)

mvn install "-Dsomeproperty=propety value"

Referred from this question

The main difference is that, with interfaces, you must define the actual implementation of each method within each class that implements said interface, so you can have many classes implement the same interface but with different behavior, while traits are just chunks of code injected in a class; another important difference is that trait methods can only be class-methods or static-methods, unlike interface methods which can also (and usually are) be instance methods.

You could check the GMap2.isLoaded() method every n milliseconds to see if the map and all its tiles were loaded (window.setTimeout() or window.setInterval() are your friends).

While this won't give you the exact event of the load completion, it should be good enough to trigger your Javascript.

This solution uses regular expressions, does not allow invalid characters to be pasted into the text box and maintains the cursor position.

using System.Text.RegularExpressions;

int CursorWas;
string WhatItWas;

private void textBox1_Enter(object sender, EventArgs e)
    {
        WhatItWas = textBox1.Text;
    }

private void textBox1_TextChanged(object sender, EventArgs e)
    {
        if (Regex.IsMatch(textBox1.Text, "^[a-zA-Z ]*$"))
        {
            WhatItWas = textBox1.Text;
        }
        else
        {
            CursorWas = textBox1.SelectionStart == 0 ? 0 : textBox1.SelectionStart - 1;
            textBox1.Text = WhatItWas;
            textBox1.SelectionStart = CursorWas;
        }
    }

Note: textBox1_TextChanged recursive call.

This works by exploiting the % properties of the list rather than the increments.

for num in range(1,100):
    if num % 4 == 1 or num % 4 ==2:
        n.append(num)
        continue
    pass

We use GIT as CVS and gradle as build tool.

Symptom

In my case one specific project with > 20'000 files froze using hierarchical view when navigating a directory with a lot of files.

Fix

1. Create new Eclipse workspace
2. Freshly clone the project into the Eclipse workspace
3. Import project into Eclipse (in our case using Gradle import)

It is greatly frustrating that CakePHP does not have a $this->Model->lastQuery();. Here are two solutions including a modified version of Handsofaten's:

1. Create a Last Query Function

To print the last query run, in your /app_model.php file add:

function lastQuery(){
    $dbo = $this->getDatasource();
    $logs = $dbo->_queriesLog;
    // return the first element of the last array (i.e. the last query)
    return current(end($logs));
}

Then to print output you can run:

debug($this->lastQuery()); // in model

OR

debug($this->Model->lastQuery()); // in controller

2. Render the SQL View (Not avail within model)

To print out all queries run in a given page request, in your controller (or component, etc) run:

$this->render('sql');

It will likely throw a missing view error, but this is better than no access to recent queries!

(As Handsofaten said, there is the /elements/sql_dump.ctp in cake/libs/view/elements/, but I was able to do the above without creating the sql.ctp view. Can anyone explain that?)

os.system() returns the (encoded) process exit value. 0 means success:

On Unix, the return value is the exit status of the process encoded in the format specified for wait(). Note that POSIX does not specify the meaning of the return value of the C system() function, so the return value of the Python function is system-dependent.

The output you see is written to stdout, so your console or terminal, and not returned to the Python caller.

If you wanted to capture stdout, use subprocess.check_output() instead:

x = subprocess.check_output(['whoami'])

The format string attack on printf you mentioned isn't specific to the "%x" formatting - in any case where printf has more formatting parameters than passed variables, it will read values from the stack that do not belong to it. You will get the same issue with %d for example. %x is useful when you want to see those values as hex.

As explained in previous answers, %08x will produce a 8 digits hex number, padded by preceding zeros.

Using the formatting in your code example in printf, with no additional parameters:

printf ("%08x %08x %08x %08x");

Will fetch 4 parameters from the stack and display them as 8-digits padded hex numbers.

In bubble sort in ith iteration you have n-i-1 inner iterations (n^2)/2 total, but in insertion sort you have maximum i iterations on i'th step, but i/2 on average, as you can stop inner loop earlier, after you found correct position for the current element. So you have (sum from 0 to n) / 2 which is (n^2) / 4 total;

That's why insertion sort is faster than bubble sort.

url_for in Flask is used for creating a URL to prevent the overhead of having to change URLs throughout an application (including in templates). Without url_for, if there is a change in the root URL of your app then you have to change it in every page where the link is present.

Syntax: url_for('name of the function of the route','parameters (if required)')

It can be used as:

@app.route('/index')
@app.route('/')
def index():
    return 'you are in the index page'

Now if you have a link the index page:you can use this:

<a href={{ url_for('index') }}>Index</a>

You can do a lot o stuff with it, for example:

@app.route('/questions/<int:question_id>'):    #int has been used as a filter that only integer will be passed in the url otherwise it will give a 404 error
def find_question(question_id):  
    return ('you asked for question{0}'.format(question_id))

For the above we can use:

<a href = {{ url_for('find_question' ,question_id=1) }}>Question 1</a>

Like this you can simply pass the parameters!

You can use + if you know all the values are strings. Jinja also provides the ~ operator, which will ensure all values are converted to string first.

{% set my_string = my_string ~ stuff ~ ', '%}

use request scope @Scope("request") to get bean for each request, or @Scope("session") to get bean for each session 'user'

To get value of li we should use $("#list li").click(function() { var selected = $(this).html();

or

var selected = $(this).text();

alert(selected);

})

Never create classes. At least the OOP kind of classes in Python being discussed.

Consider this simplistic class:

class Person(object):
    def __init__(self, id, name, city, account_balance):
        self.id = id
        self.name = name
        self.city = city
        self.account_balance = account_balance

    def adjust_balance(self, offset):
        self.account_balance += offset


if __name__ == "__main__":
    p = Person(123, "bob", "boston", 100.0)
    p.adjust_balance(50.0)
    print("done!: {}".format(p.__dict__))

vs this namedtuple version:

from collections import namedtuple

Person = namedtuple("Person", ["id", "name", "city", "account_balance"])


def adjust_balance(person, offset):
    return person._replace(account_balance=person.account_balance + offset)


if __name__ == "__main__":
    p = Person(123, "bob", "boston", 100.0)
    p = adjust_balance(p, 50.0)
    print("done!: {}".format(p))

The namedtuple approach is better because:

• namedtuples have more concise syntax and standard usage.
• In terms of understanding existing code, namedtuples are basically effortless to understand. Classes are more complex. And classes can get very complex for humans to read.
• namedtuples are immutable. Managing mutable state adds unnecessary complexity.
• class inheritance adds complexity, and hides complexity.

I can't see a single advantage to using OOP classes. Obviously, if you are used to OOP, or you have to interface with code that requires classes like Django.

BTW, most other languages have some record type feature like namedtuples. Scala, for example, has case classes. This logic applies equally there.

You can change the value of a bool all you want. As for an if:

if randombool == True:

works, but you can also use:

if randombool:

If you want to test whether something is false you can use:

if randombool == False

but you can also use:

if not randombool:

Haven't check in Excel, but this works in Libreoffice4:

The whole thing of address rewriting comes during consecutive
(a1) cut
(a2) paste

You need to interrupt the consecutiveness by putting something in-between:
(b1) cut
(b2) select some empty cells (more than 1) and drag(move) them
(b3) paste

Step (b2) is where the cell that is about to update itself stops the tracking. Quick and simple.

At a minimum you are going to need to know the column delimiter.

This is another sh1tty Google product with a terrible implemenation.

The problem I have found with this is that if you restrict an API key by IP address, it wont work... BUT far be it from Google to make this point clear... It wasn't until troubleshooting and researching I found:

API keys with an IP addresses restriction can only be used with web services that are intended for use from the server side (such as the Geocoding API and other Web Service APIs). Most of these web services have equivalent services within the Maps JavaScript API (for example, see the Geocoding Service). To use the Maps JavaScript API client side services, you will need to create a separate API key which can be secured with an HTTP referrers restriction (see Restricting an API key).

FFS Google... Pretty important piece of information that would be good to clarify on setup...

Just to add another way (even if it requires an additional module): iteration_utilities.all_monotone:

>>> from iteration_utilities import all_monotone
>>> listtimestamps = [1, 2, 3, 5, 6, 7]
>>> all_monotone(listtimestamps)
True

>>> all_monotone([1,2,1])
False

To check for DESC order:

>>> all_monotone(listtimestamps, decreasing=True)
False

>>> all_monotone([3,2,1], decreasing=True)
True

There is also a strict parameter if you need to check for strictly (if successive elements should not be equal) monotonic sequences.

It's not a problem in your case but if your sequences contains nan values then some methods will fail, for example with sorted:

def is_sorted_using_sorted(iterable):
    return sorted(iterable) == iterable

>>> is_sorted_using_sorted([3, float('nan'), 1])  # definetly False, right?
True

>>> all_monotone([3, float('nan'), 1])
False

Note that iteration_utilities.all_monotone performs faster compared to the other solutions mentioned here especially for unsorted inputs (see benchmark).

You can make an AJAX request if the url is in the same domain, e.g., same host different application. If so, I'd probably use a framework like jQuery, most likely the get method.

$.get('http://someurl.com',function(data,status) {
      ...parse the data...
},'html');

If you run into cross domain issues, then your best bet is to create a server-side action that proxies the request for you. Do your request to your server using AJAX, have the server request and return the response from the external host.

Thanks to@nickf, for pointing out the obvious problem with my original solution if the url is in a different domain.

All the set-related solutions to this problem thus far require creating an entire set before iteration.

It is possible to make this lazy, and at the same time preserve order, by iterating the list of lists and adding to a "seen" set. Then only yield a list if it is not found in this tracker set.

This unique_everseen recipe is available in the itertools docs. It's also available in the 3rd party toolz library:

from toolz import unique

k = [[1, 2], [4], [5, 6, 2], [1, 2], [3], [4]]

# lazy iterator
res = map(list, unique(map(tuple, k)))

print(list(res))

[[1, 2], [4], [5, 6, 2], [3]]

Note that tuple conversion is necessary because lists are not hashable.

You may also want to check for the length - emails are a maximum of 254 chars long. I use the apache commons validator and it doesn't check for this.

Answers given above are perfect but I suggest to use multiple smaller regex rather than a big one.
Splitting the long regex have some advantages:

• easiness to write and read
• easiness to debug
• easiness to add/remove part of regex

Generally this approach keep code easily maintainable.

Having said that, I share a piece of code that I write in Swift as example:

struct RegExp {

    /**
     Check password complexity

     - parameter password:         password to test
     - parameter length:           password min length
     - parameter patternsToEscape: patterns that password must not contains
     - parameter caseSensitivty:   specify if password must conforms case sensitivity or not
     - parameter numericDigits:    specify if password must conforms contains numeric digits or not

     - returns: boolean that describes if password is valid or not
     */
    static func checkPasswordComplexity(password password: String, length: Int, patternsToEscape: [String], caseSensitivty: Bool, numericDigits: Bool) -> Bool {
        if (password.length < length) {
            return false
        }
        if caseSensitivty {
            let hasUpperCase = RegExp.matchesForRegexInText("[A-Z]", text: password).count > 0
            if !hasUpperCase {
                return false
            }
            let hasLowerCase = RegExp.matchesForRegexInText("[a-z]", text: password).count > 0
            if !hasLowerCase {
                return false
            }
        }
        if numericDigits {
            let hasNumbers = RegExp.matchesForRegexInText("\\d", text: password).count > 0
            if !hasNumbers {
                return false
            }
        }
        if patternsToEscape.count > 0 {
            let passwordLowerCase = password.lowercaseString
            for pattern in patternsToEscape {
                let hasMatchesWithPattern = RegExp.matchesForRegexInText(pattern, text: passwordLowerCase).count > 0
                if hasMatchesWithPattern {
                    return false
                }
            }
        }
        return true
    }

    static func matchesForRegexInText(regex: String, text: String) -> [String] {
        do {
            let regex = try NSRegularExpression(pattern: regex, options: [])
            let nsString = text as NSString
            let results = regex.matchesInString(text,
                options: [], range: NSMakeRange(0, nsString.length))
            return results.map { nsString.substringWithRange($0.range)}
        } catch let error as NSError {
            print("invalid regex: \(error.localizedDescription)")
            return []
        }
    }
}

Based on the answer of @Tyler McGinnis. I made a different approach using ES6 syntax and nested routes with wrapped components:

import React, { cloneElement, Children } from 'react'
import { Route, Redirect } from 'react-router-dom'

const PrivateRoute = ({ children, authed, ...rest }) =>
  <Route
    {...rest}
    render={(props) => authed ?
      <div>
        {Children.map(children, child => cloneElement(child, { ...child.props }))}
      </div>
      :
      <Redirect to={{ pathname: '/', state: { from: props.location } }} />}
  />

export default PrivateRoute

And using it:

<BrowserRouter>
  <div>
    <PrivateRoute path='/home' authed={auth}>
      <Navigation>
        <Route component={Home} path="/home" />
      </Navigation>
    </PrivateRoute>

    <Route exact path='/' component={PublicHomePage} />
  </div>
</BrowserRouter>

As to the concrete problem with that SQLException, you need to replace

ResultSet rs = stmt.executeQuery(sql);

by

ResultSet rs = stmt.executeQuery();

because you're using the PreparedStatement subclass instead of Statement. When using PreparedStatement, you've already passed in the SQL string to Connection#prepareStatement(). You just have to set the parameters on it and then call executeQuery() method directly without re-passing the SQL string.

See also:

• JDBC tutorial - Using Prepared Statements

As to the concrete question about rs.next(), it shifts the cursor to the next row of the result set from the database and returns true if there is any row, otherwise false. In combination with the if statement (instead of the while) this means that the programmer is expecting or interested in only one row, the first row.

See also:

• Javadoc on ResultSet#next() method
• Problem with SQL, ResultSet in java

Just the heads up, there seems to be special CSS class for this called form-horizontal

input-append has another side effect, that it drops font-size to zero

You can either use (on the h4 elements, as they are block by default)

display: inline-block;

Or you can float the elements to the left/rght

float: left;

Just don't forget to clear the floats after

clear: left;

More visual example for the float left/right option as shared below by @VSB:

<h4> _x000D_
    <div style="float:left;">Left Text</div>_x000D_
    <div style="float:right;">Right Text</div>_x000D_
    <div style="clear: left;"/>_x000D_
</h4>

I'm not sure what you're trying to do, but here's something to consider: c(); won't do anything. c is an instance of the class checkbox and not a method to be called. So consider this:

public class FirstWindow extends JFrame {      public FirstWindow() {         checkbox c = new checkbox();         c.yourMethod(yourParameters); // call the method you made in checkbox     } }  public class checkbox extends JFrame {      public checkbox(yourParameters) {          // this is the constructor method used to initialize instance variables     }      public void yourMethod() // doesn't have to be void     {         // put your code here     } }

In general you want to program against an interface. This allows you to exchange the implementation at any time. This is very useful especially when you get passed an implementation you don't know.

However, there are certain situations where you prefer to use the concrete implementation. For example when serialize in GWT.

Try:

while [ $stats -gt 300 -o $stats -eq 0 ]

[ is a call to test. It is not just for grouping, like parentheses in other languages. Check man [ or man test for more information.

This problem also occurs if a 'view' (imaginary table) exists in database as same name as our new table name.

I work in Ruby and using Nokogiri I fetch the element and look to see if the result is nil.

require 'nokogiri'

What you want is org.mockito.Mockito.CALLS_REAL_METHODS according to the docs:

/**
 * Optional <code>Answer</code> to be used with {@link Mockito#mock(Class, Answer)}
 * <p>
 * {@link Answer} can be used to define the return values of unstubbed invocations.
 * <p>
 * This implementation can be helpful when working with legacy code.
 * When this implementation is used, unstubbed methods will delegate to the real implementation.
 * This is a way to create a partial mock object that calls real methods by default.
 * <p>
 * As usual you are going to read <b>the partial mock warning</b>:
 * Object oriented programming is more less tackling complexity by dividing the complexity into separate, specific, SRPy objects.
 * How does partial mock fit into this paradigm? Well, it just doesn't... 
 * Partial mock usually means that the complexity has been moved to a different method on the same object.
 * In most cases, this is not the way you want to design your application.
 * <p>
 * However, there are rare cases when partial mocks come handy: 
 * dealing with code you cannot change easily (3rd party interfaces, interim refactoring of legacy code etc.)
 * However, I wouldn't use partial mocks for new, test-driven & well-designed code.
 * <p>
 * Example:
 * <pre class="code"><code class="java">
 * Foo mock = mock(Foo.class, CALLS_REAL_METHODS);
 *
 * // this calls the real implementation of Foo.getSomething()
 * value = mock.getSomething();
 *
 * when(mock.getSomething()).thenReturn(fakeValue);
 *
 * // now fakeValue is returned
 * value = mock.getSomething();
 * </code></pre>
 */

Thus your code should look like:

import org.junit.Test;
import static org.mockito.Mockito.*;
import static org.junit.Assert.*;

public class StockTest {

    public class Stock {
        private final double price;
        private final int quantity;

        Stock(double price, int quantity) {
            this.price = price;
            this.quantity = quantity;
        }

        public double getPrice() {
            return price;
        }

        public int getQuantity() {
            return quantity;
        }

        public double getValue() {
            return getPrice() * getQuantity();
        }
    }

    @Test
    public void getValueTest() {
        Stock stock = mock(Stock.class, withSettings().defaultAnswer(CALLS_REAL_METHODS));
        when(stock.getPrice()).thenReturn(100.00);
        when(stock.getQuantity()).thenReturn(200);
        double value = stock.getValue();

        assertEquals("Stock value not correct", 100.00 * 200, value, .00001);
    }
}

The call to Stock stock = mock(Stock.class); calls org.mockito.Mockito.mock(Class<T>) which looks like this:

 public static <T> T mock(Class<T> classToMock) {
    return mock(classToMock, withSettings().defaultAnswer(RETURNS_DEFAULTS));
}

The docs of the value RETURNS_DEFAULTS tell:

/**
 * The default <code>Answer</code> of every mock <b>if</b> the mock was not stubbed.
 * Typically it just returns some empty value. 
 * <p>
 * {@link Answer} can be used to define the return values of unstubbed invocations. 
 * <p>
 * This implementation first tries the global configuration. 
 * If there is no global configuration then it uses {@link ReturnsEmptyValues} (returns zeros, empty collections, nulls, etc.)

One option that might work is using WindowsIdentity.Impersonate (and change the thread principal) to become the desired user, like so. Back to p/invoke, though, I'm afraid...

Another cheeky (and equally far from ideal) option might be to spawn a process to do the work... ProcessStartInfo accepts a .UserName, .Password and .Domain.

Finally - perhaps run the service in a dedicated account that has access? (removed as you have clarified that this isn't an option).

Declaring objects in the smallest scope improve readability.

Performance doesn't matter for today's compilers.(in this scenario)
From a maintenance perspective, 2nd option is better.
Declare and initialize variables in the same place, in the narrowest scope possible.

As Donald Ervin Knuth told:

"We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil"

i.e) situation where a programmer lets performance considerations affect the design of a piece of code. This can result in a design that is not as clean as it could have been or code that is incorrect, because the code is complicated by the optimization and the programmer is distracted by optimizing.

its anything other than the data itself, ie tcp flags, headers, crc, fcs etc..

Not 100% what you were looking for, but kind of an inside-out way of doing it:

SQL> CREATE TABLE mytable (id NUMBER, status VARCHAR2(50));

Table created.

SQL> INSERT INTO mytable VALUES (1,'Finished except pouring water on witch');

1 row created.

SQL> INSERT INTO mytable VALUES (2,'Finished except clicking ruby-slipper heels');

1 row created.

SQL> INSERT INTO mytable VALUES (3,'You shall (not?) pass');

1 row created.

SQL> INSERT INTO mytable VALUES (4,'Done');

1 row created.

SQL> INSERT INTO mytable VALUES (5,'Done with it.');

1 row created.

SQL> INSERT INTO mytable VALUES (6,'In Progress');

1 row created.

SQL> INSERT INTO mytable VALUES (7,'In progress, OK?');

1 row created.

SQL> INSERT INTO mytable VALUES (8,'In Progress Check Back In Three Days'' Time');

1 row created.

SQL> SELECT *
  2  FROM   mytable m
  3  WHERE  +1 NOT IN (INSTR(m.status,'Done')
  4            ,       INSTR(m.status,'Finished except')
  5            ,       INSTR(m.status,'In Progress'));

        ID STATUS
---------- --------------------------------------------------
         3 You shall (not?) pass
         7 In progress, OK?

The style property lets you specify values for CSS properties.

The CSS width property takes a length as its value.

Lengths require units. In quirks mode, browsers tend to assume pixels if provided with an integer instead of a length. Specify units.

e1.style.width = "400px";

I don't understand

days, hours, minutes = td.days, td.seconds // 3600, td.seconds // 60 % 60

how about this

days, hours, minutes = td.days, td.seconds // 3600, td.seconds % 3600 / 60.0

You get minutes and seconds of a minute as a float.

Even if this thread is old is the first on Google, so I'll post an Oracle equivalent to the function implemented here, using regular expressions.

Is fairly faster than nested replace(), and much cleaner.

To replace strings 'a','b','c' with 'd' in a string column from a given table

select regexp_replace(string_col,'a|b|c','d') from given_table

It is nothing else than a regular expression for several static patterns with 'or' operator.

Beware of regexp special characters!

Gradle 3.0 introduced next changes:

• compile -> api

  api keyword is the same as deprecated compile which expose this dependency for all levels

• compile -> implementation

  Is preferable way because has some advantages. implementation expose dependency only for one level up at build time (the dependency is available at runtime). As a result you have a faster build(no need to recompile consumers which are higher then 1 level up)

• provided -> compileOnly

  This dependency is available only in compile time(the dependency is not available at runtime). This dependency can not be transitive and be .aar. It can be used with compile time annotation processor and allows you to reduce a final output file

• compile -> annotationProcessor

  Very similar to compileOnly but also guarantees that transitive dependency are not visible for consumer

• apk -> runtimeOnly

  Dependency is not available in compile time but available at runtime.

I can't believe nobody offered plain shell:

I had this error and as I'm on shared hosting I don't have access to the php.ini so wasn't sure how I could fix it, the host didn't seem to have a clue either. In the end I emptied my browser cache and reloaded phpmyadmin and it came back!

To catch the names array, i use that:

$("input[name*='task']")

The main difference is when compiled in debug mode, pdb files are also created which allow debugging (so you can step through the code when its running). This however means that the code isn't optimized as much.

How many thousands of users?

I've run some TCP/IP client/server connection tests in the past on Windows 2003 Server and managed more than 70,000 connections on a reasonably low spec VM. (see here for details: http://www.lenholgate.com/blog/2005/10/the-64000-connection-question.html). I would be extremely surprised if Windows 2008 Server is limited to less than 2003 Server and, IMHO, the posting that Cloud links to is too vague to be much use. This kind of question comes up a lot, I blogged about why I don't really think that it's something that you should actually worry about here: http://www.serverframework.com/asynchronousevents/2010/12/one-million-tcp-connections.html.

Personally I'd test it and see. Even if there is no inherent limit in the Windows 2008 Server version that you intend to use there will still be practical limits based on memory, processor speed and server design.

If you want to run some 'generic' tests you can use my multi-client connection test and the associated echo server. Detailed here: http://www.lenholgate.com/blog/2005/11/windows-tcpip-server-performance.html and here: http://www.lenholgate.com/blog/2005/11/simple-echo-servers.html. These are what I used to run my own tests for my server framework and these are what allowed me to create 70,000 active connections on a Windows 2003 Server VM with 760MB of memory.

Edited to add details from the comment below...

If you're already thinking of multiple servers I'd take the following approach.

1. Use the free tools that I link to and prove to yourself that you can create a reasonable number of connections onto your target OS (beware of the Windows limits on dynamic ports which may cause your client connections to fail, search for MAX_USER_PORT).

2. during development regularly test your actual server with test clients that can create connections and actually 'do something' on the server. This will help to prevent you building the server in ways that restrict its scalability. See here: http://www.serverframework.com/asynchronousevents/2010/10/how-to-support-10000-or-more-concurrent-tcp-connections-part-2-perf-tests-from-day-0.html

Well, after some struggling, what worked for me was completely removing the current JDK, as described here:

sudo rm -rf /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk
sudo rm -rf /Library/PreferencePanes/JavaControlPanel.prefPane
sudo rm -rf /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo rm -rf /Library/LaunchAgents/com.oracle.java.Java-Updater.plist
sudo rm -rf /Library/PrivilegedHelperTools/com.oracle.java.JavaUpdateHelper
sudo rm -rf /Library/LaunchDaemons/com.oracle.java.JavaUpdateHelper.plist
sudo rm -rf /Library/Preferences/com.oracle.java.Helper-Tool.plist

Then installed 1.7.0_21, which was downloaded from here.

Now java -version prompts:

java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b12)
Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)

Taking a cue from @Mikel Yang, I found out that instead of deleting the ~/.gradle/wrapper/dists/ folder (which will means downloading the gradle files for different apps on my Android Studio), I decided to change the gradle.wrapper.properties file to any latest gradle --all.zip. So

Find 'gradle-wrapper.properties' in root project

distributionUrl=https\://services.gradle.org/distributions/gradle-{lastest}-all.zip

this way l get to save some data and time.

Argument order matters

Jersey Beans answer (all 3 examples) worked for me. After quite a bit of trial and error I realized that the order of the arguments matter.

Keeps the container running in the background: docker run -t -d <image-name>

Keeps the container running in the foreground: docker run <image-name> -t -d

It wasn't obvious to me coming from a Powershell background.

Using text nodes in jquery is a particularly delicate endeavour and most operations are made to skip them altogether.

Instead of going through the trouble of carefully avoiding the wrong nodes, why not just wrap whatever you need to replace inside a <span> for instance:

<td><span class="replaceme">8: Tap on APN and Enter <B>www</B>.</span></td>

Then:

$('.replaceme').html('Whatever <b>HTML</b> you want here.');

Using Kotlin, you can do the following to read a file from assets in Android:

try {
    val inputStream:InputStream = assets.open("helloworld.txt")
    val inputString = inputStream.bufferedReader().use{it.readText()}
    Log.d(TAG,inputString)
} catch (e:Exception){
    Log.d(TAG, e.toString())
}

cmsjr had the right solution. I just wanted to point out a couple of things for your future trigger development. If you are using the values statement in an insert in a trigger, there is a stong possibility that you are doing the wrong thing. Triggers fire once for each batch of records inserted, deleted, or updated. So if ten records were inserted in one batch, then the trigger fires once. If you are refering to the data in the inserted or deleted and using variables and the values clause then you are only going to get the data for one of those records. This causes data integrity problems. You can fix this by using a set-based insert as cmsjr shows above or by using a cursor. Don't ever choose the cursor path. A cursor in a trigger is a problem waiting to happen as they are slow and may well lock up your table for hours. I removed a cursor from a trigger once and improved an import process from 40 minutes to 45 seconds.

You may think nobody is ever going to add multiple records, but it happens more frequently than most non-database people realize. Don't write a trigger that will not work under all the possible insert, update, delete conditions. Nobody is going to use the one record at a time method when they have to import 1,000,000 sales target records from a new customer or update all the prices by 10% or delete all the records from a vendor whose products you don't sell anymore.

If anyone comes to this thread and has this issue when you remote to a VMware VM with windows 10 1903, disabling 3d in the graphics card worked for me.
