'nunique' is an option for .agg() since pandas 0.20.0, so:

df.groupby('date').agg({'duration': 'sum', 'user_id': 'nunique'})

Since you are not worried about IE, why not just use css transitions to provide the animation and jQuery to change the classes. Live example: http://jsfiddle.net/tw16/JfK6N/

#someDiv{
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}

For substracting in moment.js:

moment().subtract(1, 'months').format('MMM YYYY');

Documentation:

http://momentjs.com/docs/#/manipulating/subtract/

Before version 2.8.0, the moment#subtract(String, Number) syntax was also supported. It has been deprecated in favor of moment#subtract(Number, String).

  moment().subtract('seconds', 1); // Deprecated in 2.8.0
  moment().subtract(1, 'seconds');

As of 2.12.0 when decimal values are passed for days and months, they are rounded to the nearest integer. Weeks, quarters, and years are converted to days or months, and then rounded to the nearest integer.

  moment().subtract(1.5, 'months') == moment().subtract(2, 'months')
  moment().subtract(.7, 'years') == moment().subtract(8, 'months') //.7*12 = 8.4, rounded to 8

I know this is an older question post, but my daughter came to me with the question, and referenced this page as having possible answers. Given that she's hunting an answer for this, it's a safe assumption others might still be as well.

All are great approaches, and as with everything there's about as many way to skin a cat as there are cats to skin.

If you're looking for a left trim and a right trim of a character or string, and your trailing character/string is uniform in length, here's my suggestion:

SELECT SUBSTRING(ColName,VAR, LEN(ColName)-VAR)

Or in this question...

SELECT SUBSTRING('"this is a test message"',2, LEN('"this is a test message"')-2)

With this, you simply adjust the SUBSTRING starting point (2), and LEN position (-2) to whatever value you need to remove from your string.

It's non-iterative and doesn't require explicit case testing and above all it's inline all of which make for a cleaner execution plan.

One way we do this in our application is using IDisposable and then with using(){} blocks to ensure the cursor is reset when done.

public class OverrideCursor : IDisposable
{

  public OverrideCursor(Cursor changeToCursor)
  {
    Mouse.OverrideCursor = changeToCursor;
  }

  #region IDisposable Members

  public void Dispose()
  {
    Mouse.OverrideCursor = null;
  }

  #endregion
}

and then in your code:

using (OverrideCursor cursor = new OverrideCursor(Cursors.Wait))
{
  // Do work...
}

The override will end when either: the end of the using statement is reached or; if an exception is thrown and control leaves the statement block before the end of the statement.

Update

To prevent the cursor flickering you can do:

public class OverrideCursor : IDisposable
{
  static Stack<Cursor> s_Stack = new Stack<Cursor>();

  public OverrideCursor(Cursor changeToCursor)
  {
    s_Stack.Push(changeToCursor);

    if (Mouse.OverrideCursor != changeToCursor)
      Mouse.OverrideCursor = changeToCursor;
  }

  public void Dispose()
  {
    s_Stack.Pop();

    Cursor cursor = s_Stack.Count > 0 ? s_Stack.Peek() : null;

    if (cursor != Mouse.OverrideCursor)
      Mouse.OverrideCursor = cursor;
  }

}

I believe there is a simpler solution. You must use Html.Hidden instead of Html.HiddenFor. Look:

@Html.Hidden("CRN", ViewData["crn"]);

This will create an INPUT tag of type="hidden", with id="CRN" and name="CRN", and the correct value inside the value attribute.

Hope it helps!

This works in Chrome 26, Internet Explorer 9 and Safari 5.1.7 (without the use of a helper page, ala Nick's answer):

<script type="text/javascript">
    window.open('javascript:window.open("", "_self", "");window.close();', '_self');
</script>

The nested window.open is to make IE not display the Do you want to close this window prompt.

Unfortunately it is impossible to get Firefox to close the window.

A quote from "When Pythons Attack"

Don't terminate all of your statements with a semicolon. It's technically legal to do this in Python, but is totally useless unless you're placing more than one statement on a single line (e.g., x=1; y=2; z=3).

I realize this question was asked and answered a long time ago, but the answers don't give what I feel is the simplest solution. It's almost always a good idea to avoid loops whenever possible, and matplotlib's plot is capable of plotting multiple lines with one command. If x and y are arrays, then plot draws one line for every column.

In your case, you can do the following:

x=np.array([-1 ,0.5 ,1,-0.5])
xx = np.vstack([x[[0,2]],x[[1,3]]])
y=np.array([ 0.5,  1, -0.5, -1])
yy = np.vstack([y[[0,2]],y[[1,3]]])
plt.plot(xx,yy, '-o')

Have a long list of x's and y's, and want to connect adjacent pairs?

xx = np.vstack([x[0::2],x[1::2]])
yy = np.vstack([y[0::2],y[1::2]])

Want a specified (different) color for the dots and the lines?

plt.plot(xx,yy, '-ok', mfc='C1', mec='C1')

This is an old question, but one that is frequently visited and clear recommendations are now available from RFC 7303 which obsoletes RFC3023. In a nutshell (section 9.2):

The registration information for text/xml is in all respects the same
as that given for application/xml above (Section 9.1), except that
the "Type name" is "text".

Structure types should, whenever practical, either have all of their state encapsulated in public fields which may independently be set to any values which are valid for their respective type, or else behave as a single unified value which can only bet set via constructor, factory, method, or else by passing an instance of the struct as an explicit ref parameter to one of its public methods. Contrary to what some people claim, that there's nothing wrong with a struct having public fields, if it is supposed to represent a set of values which may sensibly be either manipulated individually or passed around as a group (e.g. the coordinates of a point). Historically, there have been problems with structures that had public property setters, and a desire to avoid public fields (implying that setters should be used instead) has led some people to suggest that mutable structures should be avoided altogether, but fields do not have the problems that properties had. Indeed, an exposed-field struct is the ideal representation for a loose collection of independent variables, since it is just a loose collection of variables.

In your particular example, however, it appears that the two fields of your struct are probably not supposed to be independent. There are three ways your struct could sensibly be designed:

• You could have the only public field be the string, and then have a read-only "helper" property called length which would report its length if the string is non-null, or return zero if the string is null.

• You could have the struct not expose any public fields, property setters, or mutating methods, and have the contents of the only field--a private string--be specified in the object's constructor. As above, length would be a property that would report the length of the stored string.

• You could have the struct not expose any public fields, property setters, or mutating methods, and have two private fields: one for the string and one for the length, both of which would be set in a constructor that takes a string, stores it, measures its length, and stores that. Determining the length of a string is sufficiently fast that it probably wouldn't be worthwhile to compute and cache it, but it might be useful to have a structure that combined a string and its GetHashCode value.

It's important to be aware of a detail with regard to the third design, however: if non-threadsafe code causes one instance of the structure to be read while another thread is writing to it, that may cause the accidental creation of a struct instance whose field values are inconsistent. The resulting behaviors may be a little different from those that occur when classes are used in non-threadsafe fashion. Any code having anything to do with security must be careful not to assume that structure fields will be in a consistent state, since malicious code--even in a "full trust" enviroment--can easily generate structs whose state is inconsistent if that's what it wants to do.

PS -- If you wish to allow your structure to be initialized using an assignment from a string, I would suggest using an implicit conversion operator and making Length be a read-only property that returns the length of the underlying string if non-null, or zero if the string is null.

AutoCloseable (introduced in Java 7) makes it possible to use the try-with-resources idiom:

public class MyResource implements AutoCloseable {

    public void close() throws Exception {
        System.out.println("Closing!");
    }

}

Now you can say:

try (MyResource res = new MyResource()) {
    // use resource here
}

and JVM will call close() automatically for you.

Closeable is an older interface. For some reason To preserve backward compatibility, language designers decided to create a separate one. This allows not only all Closeable classes (like streams throwing IOException) to be used in try-with-resources, but also allows throwing more general checked exceptions from close().

When in doubt, use AutoCloseable, users of your class will be grateful.

Ok if anyone else is having this problem this may be your answer:

If you are trying to hide absolute positioned elements make sure the container of those absolute positioned elements is relatively positioned.

I would recommend you to make use of the $.post or $.get syntax of jQuery for simple cases:

$.post('superman', { field1: "hello", field2 : "hello2"}, 
    function(returnedData){
         console.log(returnedData);
});

If you need to catch the fail cases, just do this:

$.post('superman', { field1: "hello", field2 : "hello2"}, 
    function(returnedData){
         console.log(returnedData);
}).fail(function(){
      console.log("error");
});

Additionally, if you always send a JSON string, you can use $.getJSON or $.post with one more parameter at the very end.

$.post('superman', { field1: "hello", field2 : "hello2"}, 
     function(returnedData){
        console.log(returnedData);
}, 'json');

Just make and use this function:

function format(str, args) {
   for (i = 0; i < args.length; i++)
      str = str.replace("{" + i + "}", args[i]);
   return str;
}

If you don't want to change the str parameter, then before the for loop, clone (duplicate) it to a new string (make a new copy of str), and set the copy in the for loop and at last return it instead of the parameter itself.

In C# (Sharp) it is simple create to a copy by just calling String.Clone(), but I don't know how in JavaScript, but you can search on Google or surf on the Internet and learn ways to do it.

I just gave you my idea about string format in JavaScript.

I had the same problem and solved it by updating the Android SDK Build-Tools in Android Studio.

step 1 - Double shift and type SDK manager, this will open the SDK manager

step 2 - Then on the second tab (SDK Tools), update the Android SDK Build-Tools and the error message should go away.

if this does not resolve check the option in Setting tab,use detected Adb tool in Setting tab

I resolved the same issue with a recursive chown on the parent folder:

sudo chown -R postgres:postgres /home/my_user/export_folder

(my export being in /home/my_user/export_folder/export_1.csv)

Server file only change name folder

etc/mysql
rename
mysql-

Another option is using a map as a set. You use just the keys and having the value be something like a boolean that's always true. Then you can easily check if the map contains the key or not. This is useful if you need the behavior of a set, where if you add a value multiple times it's only in the set once.

Here's a simple example where I add random numbers as keys to a map. If the same number is generated more than once it doesn't matter, it will only appear in the final map once. Then I use a simple if check to see if a key is in the map or not.

package main

import (
    "fmt"
    "math/rand"
)

func main() {
    var MAX int = 10

    m := make(map[int]bool)

    for i := 0; i <= MAX; i++ {
        m[rand.Intn(MAX)] = true
    }

    for i := 0; i <= MAX; i++ {
        if _, ok := m[i]; ok {
            fmt.Printf("%v is in map\n", i)
        } else {
            fmt.Printf("%v is not in map\n", i)
        }
    }
}

Here it is on the go playground

Note that there is no variable interpolation in Java. Variable interpolation is variable substitution with its value inside a string. An example in Ruby:

#!/usr/bin/ruby

age = 34
name = "William"

puts "#{name} is #{age} years old"

The Ruby interpreter automatically replaces variables with its values inside a string. The fact, that we are going to do interpolation is hinted by sigil characters. In Ruby, it is #{}. In Perl, it could be $, % or @. Java would only print such characters, it would not expand them.

Variable interpolation is not supported in Java. Instead of this, we have string formatting.

package com.zetcode;

public class StringFormatting 
{
    public static void main(String[] args) 
    {
        int age = 34;
        String name = "William";

        String output = String.format("%s is %d years old.", name, age);
    
        System.out.println(output);
    }
}

In Java, we build a new string using the String.format() method. The outcome is the same, but the methods are different.

See http://en.wikipedia.org/wiki/Variable_interpolation

Edit As of 2019, JEP 326 (Raw String Literals) was withdrawn and superseded by multiple JEPs eventually leading to JEP 378: Text Blocks delivered in Java 15.

A text block is a multi-line string literal that avoids the need for most escape sequences, automatically formats the string in a predictable way, and gives the developer control over the format when desired.

However, still no string interpolation:

Non-Goals: … Text blocks do not directly support string interpolation. Interpolation may be considered in a future JEP. In the meantime, the new instance method String::formatted aids in situations where interpolation might be desired.

I was thinking that it might be useful to compare the runtimes of the different approaches so I made a benchmark (using simple_benchmark library)

I) Benchmark having tuples with 2 elements

As you may expect to select the first element from tuples by index 0 shows to be the fastest solution very close to the unpacking solution by expecting exactly 2 values

import operator
import random

from simple_benchmark import BenchmarkBuilder

b = BenchmarkBuilder()



@b.add_function()
def rakesh_by_index(l):
    return [i[0] for i in l]


@b.add_function()
def wayneSan_zip(l):
    return list(list(zip(*l))[0])


@b.add_function()
def bcattle_itemgetter(l):
     return list(map(operator.itemgetter(0), l))


@b.add_function()
def ssoler_upacking(l):
    return [idx for idx, val in l]

@b.add_function()
def kederrack_unpacking(l):
    return [f for f, *_ in l]



@b.add_arguments('Number of tuples')
def argument_provider():
    for exp in range(2, 21):
        size = 2**exp
        yield size, [(random.choice(range(100)), random.choice(range(100))) for _ in range(size)]


r = b.run()
r.plot()

II) Benchmark having tuples with 2 or more elements

import operator
import random

from simple_benchmark import BenchmarkBuilder

b = BenchmarkBuilder()

@b.add_function()
def kederrack_unpacking(l):
    return [f for f, *_ in l]


@b.add_function()
def rakesh_by_index(l):
    return [i[0] for i in l]


@b.add_function()
def wayneSan_zip(l):
    return list(list(zip(*l))[0])


@b.add_function()
def bcattle_itemgetter(l):
     return list(map(operator.itemgetter(0), l))


@b.add_arguments('Number of tuples')
def argument_provider():
    for exp in range(2, 21):
        size = 2**exp
        yield size, [tuple(random.choice(range(100)) for _
                     in range(random.choice(range(2, 100)))) for _ in range(size)]

from pylab import rcParams
rcParams['figure.figsize'] = 12, 7

r = b.run()
r.plot()

Your key must not be publicly viewable for SSH to work. Use this command if needed:

chmod 400 yourPublicKeyFile.pem

Well, I spent a lot of time on this issue. To get an answer working with Chrome AND IE, I had to change my approach. The idea is to avoid removing the selected option (because cannot remove it properly with IE). => this implies to select option not by adding or setting the selected attribute on the option, but to choose an option at the "select" level using the selectedIndex prop.

Before :

$('#myselect option:contains("value")').attr('selected','selected');
$('#myselect option:contains("value")').removeAttr('selected'); => KO with IE

After :

$('#myselect').prop('selectedIndex', $('#myselect option:contains("value")').index());
$('#myselect').prop('selectedIndex','-1'); => OK with all browsers

Hope it will help

FATAL:  could not load server certificate file "/etc/ssl/certs/ssl-cert-snakeoil.pem": No such file or directory
LOG:  database system is shut down
pg_ctl: could not start server

I have a missing ssl-cert-snakeoil.pem file so i created it using make-ssl-cert generate-default-snakeoil --force-overwrite And it worked fine.

What about having different names for your dev and prod servers? That should avoid any confusions and you'd not have to edit the hosts file every time.

In my case, the Hibernate was looking for columns in a snake case, like create_date, while the columns in the DB were in the camel case, e.g., createDate. Adding

spring:
  jpa:
    hibernate:
      naming: # must tell spring/jpa/hibernate to use the column names as specified, not snake case
        physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
        implicit-strategy: org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl

to the application.ymlhelped fix the problem.

One way to create a quick test query in Windows via an ODBC connection is using the DQY format.

To achieve this, create a DQY file (e.g. test.dqy) containing the magic first two lines (XLODBC and 1) as below, followed by your ODBC connection string on the third line and your query on the fourth line (all on one line), e.g.:

XLODBC
1
Driver={Microsoft ODBC for Oracle};server=DB;uid=scott;pwd=tiger;
SELECT COUNT(1) n FROM emp

Then, if you open the file by double-clicking it, it will open in Excel and populate the worksheet with the results of the query.

cp somefile somefile_`date +%d%b%Y`

A fragment lives inside an activity, while an activity lives by itself.

For Googlers:

• DO NOT mix statefulness with state transfer mechanisms

STATEFULNESS

• Stateful = save authorization info on server side, this is the traditional way
• Stateless = save authorization info on client side, along with a signature to ensure integrity

MECHANISMS

• Cookie = a special header with special treatment (access, storage, expiration, security, auto-transfer) by browsers
• Custom Headers = e.g. Authorization, are just headers without any special treatment, client has to manage all aspects of the transfer
• Other. Other transfer mechanisms may be utilized, e.g. query string was a choice to transfer auth ID for a while but was abandoned for its insecurity

STATEFULNESS COMPARISON

• "Stateful authorization" means the server stores and maintains user authorization info on server, making authorizations part of the application state
• This means client only need to keep an "auth ID" and the server can read auth detail from its database
• This implies that server keeps a pool of active auths (users that are logged in) and will query this info for every request
• "Stateless authorization" means the server does not store and maintain user auth info, it simply does not know which users are signed in, and rely on the client to produce auth info
• Client will store complete auth info like who you are (user ID), and possibly permissions, expiration time, etc., this is more than just auth ID, so it is given a new name token
• Obviously client cannot be trusted, so auth data is stored along with a signature generated from hash(data + secret key), where secret key is only known to server, so the integrity of token data can be verified
• Note that token mechanism merely ensures integrity, but not confidentiality, client has to implement that
• This also means for every request client has to submit a complete token, which incurs extra bandwidth

MECHANISM COMPARISON

• "Cookie" is just a header, but with some preloaded operations on browsers
• Cookie can be set by server and auto-saved by client, and will auto-send for same domain
• Cookie can be marked as httpOnly thus prevent client JavaScript access
• Preloaded operations may not be available on platforms other than browsers (e.g. mobile), which may lead to extra efforts
• "Custom headers" are just custom headers without preloaded operations
• Client is responsible to receive, store, secure, submit and update the custom header section for each requests, this may help prevent some simple malicious URL embedding

SUM-UP

• There is no magic, auth state has to be stored somewhere, either at server or client
• You may implement stateful/stateless with either cookie or other custom headers
• When people talk about those things their default mindset is mostly: stateless = token + custom header, stateful = auth ID + cookie; these are NOT the only possible options
• They have pros and cons, but even for encrypted tokens you should not store sensitive info

My best guess at why you had problems with the ----- covering your first result is that you actually read the input line from a file. That line probably had a \r on the end so you ended up with something like this:

-----------test2-------test3

What happened is the machine actually printed this:

test-------test2-------test3\r-------

That means, because of the carriage return at the end of test3, that the dashes after test3 were printed over the top of the first word (and a few of the existing dashes between test and test2 but you wouldn't notice that because they were already dashes).

What is the most pythonic way to pad a numeric string with zeroes to the left, i.e., so the numeric string has a specific length?

str.zfill is specifically intended to do this:

>>> '1'.zfill(4)
'0001'

Note that it is specifically intended to handle numeric strings as requested, and moves a + or - to the beginning of the string:

>>> '+1'.zfill(4)
'+001'
>>> '-1'.zfill(4)
'-001'

Here's the help on str.zfill:

>>> help(str.zfill)
Help on method_descriptor:

zfill(...)
    S.zfill(width) -> str

    Pad a numeric string S with zeros on the left, to fill a field
    of the specified width. The string S is never truncated.

Performance

This is also the most performant of alternative methods:

>>> min(timeit.repeat(lambda: '1'.zfill(4)))
0.18824880896136165
>>> min(timeit.repeat(lambda: '1'.rjust(4, '0')))
0.2104538488201797
>>> min(timeit.repeat(lambda: f'{1:04}'))
0.32585487607866526
>>> min(timeit.repeat(lambda: '{:04}'.format(1)))
0.34988890308886766

To best compare apples to apples for the % method (note it is actually slower), which will otherwise pre-calculate:

>>> min(timeit.repeat(lambda: '1'.zfill(0 or 4)))
0.19728074967861176
>>> min(timeit.repeat(lambda: '%04d' % (0 or 1)))
0.2347015216946602

Implementation

With a little digging, I found the implementation of the zfill method in Objects/stringlib/transmogrify.h:

static PyObject *
stringlib_zfill(PyObject *self, PyObject *args)
{
    Py_ssize_t fill;
    PyObject *s;
    char *p;
    Py_ssize_t width;

    if (!PyArg_ParseTuple(args, "n:zfill", &width))
        return NULL;

    if (STRINGLIB_LEN(self) >= width) {
        return return_self(self);
    }

    fill = width - STRINGLIB_LEN(self);

    s = pad(self, fill, 0, '0');

    if (s == NULL)
        return NULL;

    p = STRINGLIB_STR(s);
    if (p[fill] == '+' || p[fill] == '-') {
        /* move sign to beginning of string */
        p[0] = p[fill];
        p[fill] = '0';
    }

    return s;
}

Let's walk through this C code.

It first parses the argument positionally, meaning it doesn't allow keyword arguments:

>>> '1'.zfill(width=4)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: zfill() takes no keyword arguments

It then checks if it's the same length or longer, in which case it returns the string.

>>> '1'.zfill(0)
'1'

zfill calls pad (this pad function is also called by ljust, rjust, and center as well). This basically copies the contents into a new string and fills in the padding.

static inline PyObject *
pad(PyObject *self, Py_ssize_t left, Py_ssize_t right, char fill)
{
    PyObject *u;

    if (left < 0)
        left = 0;
    if (right < 0)
        right = 0;

    if (left == 0 && right == 0) {
        return return_self(self);
    }

    u = STRINGLIB_NEW(NULL, left + STRINGLIB_LEN(self) + right);
    if (u) {
        if (left)
            memset(STRINGLIB_STR(u), fill, left);
        memcpy(STRINGLIB_STR(u) + left,
               STRINGLIB_STR(self),
               STRINGLIB_LEN(self));
        if (right)
            memset(STRINGLIB_STR(u) + left + STRINGLIB_LEN(self),
                   fill, right);
    }

    return u;
}

After calling pad, zfill moves any originally preceding + or - to the beginning of the string.

Note that for the original string to actually be numeric is not required:

>>> '+foo'.zfill(10)
'+000000foo'
>>> '-foo'.zfill(10)
'-000000foo'

JSON is just a subset of JavaScript. But eval evaluates the full JavaScript language and not just the subset that’s JSON.

Add a View:

1. Right-Click View Folder
2. Click Add -> View
3. Click Create a strongly-typed view
4. Select your User class
5. Select List as the Scaffold template

Add a controller and action method to call the view:

public ActionResult Index()
{
    var users = DataContext.GetUsers();
    return View(users);
}

I you have the char '9', it will store its ASCII code, so to get the int value, you have 2 ways

char x = '9';
int y = Character.getNumericValue(x);   //use a existing function
System.out.println(y + " " + (y + 1));  // 9  10

or

char x = '9';
int y = x - '0';                        // substract '0' code to get the difference
System.out.println(y + " " + (y + 1));  // 9  10

And it fact, this works also :

char x = 9;
System.out.println(">" + x + "<");     //>  < prints a horizontal tab
int y = (int) x;
System.out.println(y + " " + (y + 1)); //9 10

You store the 9 code, which corresponds to a horizontal tab (you can see when print as String, bu you can also use it as int as you see above

The decision to use 1st January 1753 (1753-01-01) as the minimum date value for a datetime in SQL Server goes back to its Sybase origins.

The significance of the date itself though can be attributed to this man.

Philip Stanhope, 4th Earl of Chesterfield. Who steered the Calendar (New Style) Act 1750 through the British Parliament. This legislated for the adoption of the Gregorian calendar for Britain and its then colonies.

There were some missing days _{(internet archive link)} in the British calendar in 1752 when the adjustment was finally made from the Julian calendar. September 3, 1752 to September 13, 1752 were lost.

Kalen Delaney explained the choice this way

So, with 12 days lost, how can you compute dates? For example, how can you compute the number of days between October 12, 1492, and July 4, 1776? Do you include those missing 12 days? To avoid having to solve this problem, the original Sybase SQL Server developers decided not to allow dates before 1753. You can store earlier dates by using character fields, but you can't use any datetime functions with the earlier dates that you store in character fields.

The choice of 1753 does seem somewhat anglocentric however as many catholic countries in Europe had been using the calendar for 170 years before the British implementation (originally delayed due to opposition by the church). Conversely many countries did not reform their calendars until much later, 1918 in Russia. Indeed the October Revolution of 1917 started on 7 November under the Gregorian calendar.

Both datetime and the new datetime2 datatype mentioned in Joe's answer do not attempt to account for these local differences and simply use the Gregorian Calendar.

So with the greater range of datetime2

SELECT CONVERT(VARCHAR, DATEADD(DAY,-5,CAST('1752-09-13' AS DATETIME2)),100)

Returns

Sep  8 1752 12:00AM

One final point with the datetime2 data type is that it uses the proleptic Gregorian calendar projected backwards to well before it was actually invented so is of limited use in dealing with historic dates.

This contrasts with other Software implementations such as the Java Gregorian Calendar class which defaults to following the Julian Calendar for dates until October 4, 1582 then jumping to October 15, 1582 in the new Gregorian calendar. It correctly handles the Julian model of leap year before that date and the Gregorian model after that date. The cutover date may be changed by the caller by calling setGregorianChange().

A fairly entertaining article discussing some more peculiarities with the adoption of the calendar can be found here.

You can do it with initializer list:

std::vector<unsigned int> array;

// First argument is an iterator to the element BEFORE which you will insert:
// In this case, you will insert before the end() iterator, which means appending value
// at the end of the vector.
array.insert(array.end(), { 1, 2, 3, 4, 5, 6 });

Here is a simplified version: (albeit not elegant, but easy-to-follow)

$("#yourButton").toggle(function() 
{
        $('#target').removeClass("a").addClass("b"); //Adds 'a', removes 'b'

}, function() {
        $('#target').removeClass("b").addClass("a"); //Adds 'b', removes 'a'

});

Alternatively, a similar solution:

$('#yourbutton').click(function()
{
     $('#target').toggleClass('a b'); //Adds 'a', removes 'b' and vice versa
});

Wanted to post this as a comment as a side note to the accepted answer, but that got a bit unclear. So purely as a side note:

If you have no need for the objects themselves and you want to have your project clear of further unused classes, you can parse with something like:

var list = JObject.Parse(json)["People"].Select(el => new { FirstName = (string)el["FirstName"], LastName = (string)el["LastName"] }).ToList();

var firstNames = list.Select(p => p.FirstName).ToList();
var lastNames = list.Select(p => p.LastName).ToList();

Even when using a strongly typed person class, you can still skip the root object by creating a list with JObject.Parse(json)["People"].ToObject<List<Person>>() Of course, if you do need to reuse the objects, it's better to create them from the start. Just wanted to point out the alternative ;)

in my case I would install django (

pip install django

) and it has a same problem with ssl certificate (Cannot fetch index base URL http://pypi.python.org/simple/ )

it's from virtualenv so DO :

FIRST: delete your virtualenv

deactivate rm -rf env

SECOND: check have pip

pip3 -V

if you don't have

sudo apt-get install python3-pip

FINALLY:

install virtualenv with nosite-packages and make your virenviroment

sudo pip3 install virtualenv virtualenv --no-site-packages -p /usr/bin/python3.6

. env/bin/activate

Git is just trying to guess for you what you are trying to do. It is making every attempt to preserve unbroken history. Of course, it is not perfect. So git mv allows you to be explicit with your intention and to avoid some errors.

Consider this example. Starting with an empty repo,

git init
echo "First" >a
echo "Second" >b
git add *
git commit -m "initial commit"
mv a c
mv b a
git status

Result:

# On branch master
# Changes not staged for commit:
#   (use "git add/rm <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#   modified:   a
#   deleted:    b
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   c
no changes added to commit (use "git add" and/or "git commit -a")

Autodetection failed :( Or did it?

$ git add *
$ git commit -m "change"
$ git log c

$ git log --follow c

    initial commit

Now try instead (remember to delete the .git folder when experimenting):

git init
echo "First" >a
echo "Second" >b
git add *
git commit -m "initial commit"
git mv a c
git status

So far so good:

# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   renamed:    a -> c


git mv b a
git status

Now, nobody is perfect:

# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   modified:   a
#   deleted:    b
#   new file:   c
#

Really? But of course...

git add *
git commit -m "change"
git log c
git log --follow c

...and the result is the same as above: only --follow shows the full history.

Now, be careful with renaming, as either option can still produce weird effects. Example:

git init
echo "First" >a
git add a
git commit -m "initial a"
echo "Second" >b
git add b
git commit -m "initial b"

git mv a c
git commit -m "first move"
git mv b a
git commit -m "second move"

git log --follow a

git mv a c
git mv b a

    initial a

Ups... Now the history is going back to initial a instead of initial b, which is wrong. So when we did two moves at a time, Git became confused and did not track the changes properly. By the way, in my experiments the same happened when I deleted/created files instead of using git mv. Proceed with care; you've been warned...

\B is not \b e.g. negative \b

pass-key here is no word boundary beside - so it matches \B in your first example there are word boundary beside cat so it matches \b

similar rules apply for others too. \W is negative of \w \UPPER CASE is negative of \LOWER CASE

If you know the white space is only due to spaces, you can use:

$string = str_replace(' ','',$string); 

But if it could be due to space, tab...you can use:

$string = preg_replace('/\s+/','',$string);

As said before, @Column(unique = true) is a shortcut to UniqueConstraint when it is only a single field.

From the example you gave, there is a huge difference between both.

@Column(unique = true)
@ManyToOne(optional = false, fetch = FetchType.EAGER)
private ProductSerialMask mask;

@Column(unique = true)
@ManyToOne(optional = false, fetch = FetchType.EAGER)
private Group group;

This code implies that both mask and group have to be unique, but separately. That means that if, for example, you have a record with a mask.id = 1 and tries to insert another record with mask.id = 1, you'll get an error, because that column should have unique values. The same aplies for group.

On the other hand,

@Table(
   name = "product_serial_group_mask", 
   uniqueConstraints = {@UniqueConstraint(columnNames = {"mask", "group"})}
)

Implies that the values of mask + group combined should be unique. That means you can have, for example, a record with mask.id = 1 and group.id = 1, and if you try to insert another record with mask.id = 1 and group.id = 2, it'll be inserted successfully, whereas in the first case it wouldn't.

If you'd like to have both mask and group to be unique separately and to that at class level, you'd have to write the code as following:

@Table(
        name = "product_serial_group_mask",
        uniqueConstraints = {
                @UniqueConstraint(columnNames = "mask"),
                @UniqueConstraint(columnNames = "group")
        }
)

This has the same effect as the first code block.

On Ubuntu system, I purged the PostgreSQL and re-installed it. All the databases are restored. This solved the problem for me.

Advice - Take the backup of the databases to be on the safer side.

Solution

The date format that you requested is called ODBC format (code 120).

To actually calculate the values that you requested, include the following in your SQL.

Copy, paste...

DECLARE
    @FirstDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, -1, GETDATE() - 2)) ), DATEADD(m, -1, GETDATE() - 1)))
    , @LastDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(GETDATE()) ), GETDATE()))

...and use in your code:

• @FirstDayOfLastMonth
• @LastDayOfLastMonth

Be aware that it has to be pasted earlier than any statements that reference the parameters, but from that point on you can reference @FirstDayOfLastMonth and @LastDayOfLastMonth in your code.

Example

Let's see some code in action:

DECLARE
    @FirstDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, -1, GETDATE() - 2)) ), DATEADD(m, -1, GETDATE() - 1)))
    , @LastDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(GETDATE()) ), GETDATE()))

SELECT
    'First day of last month' AS Title, CONVERT(VARCHAR, @FirstDayOfLastMonth , 120) AS [ODBC]
UNION 

SELECT 
    'Last day of last month' AS Title, CONVERT(VARCHAR, @LastDayOfLastMonth , 120) AS [ODBC]

Run the above code to produce the following output:

Note: Bear in mind that today's date for me is 12th September, 2016.

More (for completeness' sake)

Common date parameters

Are you left wanting more?

To set up a more comprehensive range of handy date related parameters, include the following in your SQL:

DECLARE
    @FirstDayOfCurrentWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 0, GETDATE()), 0))
    , @LastDayOfCurrentWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 0, GETDATE()), 6))
    , @FirstDayOfLastWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 7, GETDATE()), 0))
    , @LastDayOfLastWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 7, GETDATE()), 6))
    , @FirstDayOfNextWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 0, GETDATE()), 7))
    , @LastDayOfNextWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 0, GETDATE()), 13))
    , @FirstDayOfCurrentMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(GETDATE() - 1) ), GETDATE()))
    , @LastDayOfCurrentMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, 1, GETDATE())) ), DATEADD(m, 1, GETDATE())))
    , @FirstDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, -1, GETDATE() - 2)) ), DATEADD(m, -1, GETDATE() - 1)))
    , @LastDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(GETDATE()) ), GETDATE()))
    , @FirstDayOfNextMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, 1, GETDATE() - 1)) ), DATEADD(m, 1, GETDATE())))
    , @LastDayOfNextMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, 2, GETDATE())) ), DATEADD(m, 2, GETDATE())))
    , @FirstDayOfCurrentYear DATETIME = CONVERT(DATE, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()), 0))
    , @LastDayOfCurrentYear DATETIME = CONVERT(DATE, DATEADD(ms, -2, DATEADD(YEAR, 0, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()) + 1, 0))))
    , @FirstDayOfLastYear DATETIME = CONVERT(DATE, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()) - 1, 0))
    , @LastDayOfLastYear DATETIME = CONVERT(DATE, DATEADD(ms, -2, DATEADD(YEAR, 0, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()), 0))))
    , @FirstDayOfNextYear DATETIME = CONVERT(DATE, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()) + 1, 0))
    , @LastDayOfNextYear DATETIME = CONVERT(DATE, DATEADD(ms, -2, DATEADD(YEAR, 0, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()) + 2, 0))))

It would make most sense to include it earlier on, preferably at the top of your procedure or SQL query.

Once declared, the parameters can be referenced anywhere in your code, as many times as you need them.

Example

Let's see some code in action:

DECLARE
    @FirstDayOfCurrentWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 0, GETDATE()), 0))
    , @LastDayOfCurrentWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 0, GETDATE()), 6))
    , @FirstDayOfLastWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 7, GETDATE()), 0))
    , @LastDayOfLastWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 7, GETDATE()), 6))
    , @FirstDayOfNextWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 0, GETDATE()), 7))
    , @LastDayOfNextWeek DATETIME = CONVERT(DATE, DATEADD(WEEK, DATEDIFF(WEEK, 0, GETDATE()), 13))
    , @FirstDayOfCurrentMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(GETDATE() - 1) ), GETDATE()))
    , @LastDayOfCurrentMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, 1, GETDATE())) ), DATEADD(m, 1, GETDATE())))
    , @FirstDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, -1, GETDATE() - 2)) ), DATEADD(m, -1, GETDATE() - 1)))
    , @LastDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(GETDATE()) ), GETDATE()))
    , @FirstDayOfNextMonth DATETIME = CONVERT(DATE, DATEADD(d, -( DAY(DATEADD(m, 1, GETDATE() - 1)) ), DATEADD(m, 1, GETDATE())))

    , @FirstDayOfCurrentYear DATETIME = CONVERT(DATE, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()), 0))
    , @LastDayOfCurrentYear DATETIME = CONVERT(DATE, DATEADD(ms, -2, DATEADD(YEAR, 0, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()) + 1, 0))))
    , @FirstDayOfLastYear DATETIME = CONVERT(DATE, DATEADD(YEAR, DATEDIFF(YEAR, 0, GETDATE()) - 1, 0))

There is a GetName function on the SqlDataReader which accepts the column index and returns the name of the column.

Conversely, there is a GetOrdinal which takes in a column name and returns the column index.

In relative layout you need specify textview height:

android:layout_height="100dp"

Or specify lines attribute:

android:lines="3"

I know this has already been answered, but I stumbled across this question and went down the path of using format, which works, but it returns them as strings when I wanted integers.

I just realized that moment comes with date, month and year methods that return the actual integers for each method.

moment().date()
moment().month()  // jan=0, dec=11
moment().year()

Your also have to register the receiver in onCreate(), like this:

IntentFilter filter = new IntentFilter();
filter.addAction("csinald.meg");
registerReceiver(receiver, filter);

what you want is:

    MY_FIELD=
        case 
            when (selectField1 = 1) then Field1
                                 else Field2        
        end,

in the select

However, y don't you just not show that column in your program?

This appears to be an (undocumented) "GNU extension": [correction: I finally found a mention in the docs. See below.]

The following command uses the -dM option to print all preprocessor defines; since the input "file" is empty, it shows exactly the predefined macros. It was run with gcc-4.7.3 on a standard ubuntu install. You can see that the preprocessor is standard-aware. In total, there 243 macros with -std=gnu99 and 240 with -std=c99; I filtered the output for relevance.

$ cpp --std=c89 -dM < /dev/null | grep linux
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1

$ cpp --std=gnu89 -dM < /dev/null | grep linux
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1
#define linux 1

$ cpp --std=c99 -dM < /dev/null | grep linux
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1

$ cpp --std=gnu99 -dM < /dev/null | grep linux
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1
#define linux 1

The "gnu standard" versions also #define unix. (Using c11 and gnu11 produces the same results.)

I suppose they had their reasons, but it seems to me to make the default installation of gcc (which compiles C code with -std=gnu89 unless otherwise specified) non-conformant, and -- as in this question -- surprising. Polluting the global namespace with macros whose names don't begin with an underscore is not permitted in a conformant implementation. (6.8.10p2: "Any other predefined macro names shall begin with a leading underscore followed by an uppercase letter or a second underscore," but, as mentioned in Appendix J.5 (portability issues), such names are often predefined.)

When I originally wrote this answer, I wasn't able to find any documentation in gcc about this issue, but I did finally discover it, not in C implementation-defined behaviour nor in C extensions but in the cpp manual section 3.7.3, where it notes that:

We are slowly phasing out all predefined macros which are outside the reserved namespace. You should never use them in new programs…

I met this problem with typescript but forgot to add ts and tsx suffix to resolve entry.

module.exports = {
  ...
  resolve: {
    extensions: ['.js', '.jsx', '.ts', '.tsx'],
  },
};

This does the job for me

If your goal is to drop the dataframe, then you need to pass all columns. For me: the best way is to pass a list comprehension to the columns kwarg. This will then work regardless of the different columns in a df.

import pandas as pd

web_stats = {'Day': [1, 2, 3, 4, 2, 6],
             'Visitors': [43, 43, 34, 23, 43, 23],
             'Bounce_Rate': [3, 2, 4, 3, 5, 5]}
df = pd.DataFrame(web_stats)

df.drop(columns=[i for i in check_df.columns])

I met the same problem. I found the solution in the solution from kb.vmware.com.
It works for me by adding

usb.quirks.device0 = "0xvid:0xpid skip-refresh"

Detail as below:

1. Shut down the virtual machine and quit Workstation/Fusion.
   
   Caution: Do not skip this step.
    
2. Open the vmware.log file within the virtual machine bundle. For more information, see Locating a virtual machine bundle in VMware Workstation/Fusion (1007599).
3. In the Filter box at the top of the Console window, enter the name of the device manufacturer.
   
   For example, if you enter the name Apple, you see a line that looks similar to:
   
   

   vmx | USB: Found device [name:Apple\ IR\ Receiver vid:05ac pid:8240 path:13/7/2 speed:full family:hid]

   
   
   The line has the name of the USB device and its vid and pid information. Make a note of the vid and pid values.
    

4. Open the .vmx file using a text editor. For more information, see Editing the .vmx file for your Workstation/Fusion virtual machine (1014782).
5. Add this line to the .vmx file, replacing vid and pid with the values noted in Step 2, each prefixed by the number 0 and the letter x .
   
   

   usb.quirks.device0 = "0xvid:0xpid skip-reset"
   
   

   For example, for the Apple device found in step 2, this line is:
   
   

   usb.quirks.device0 = "0x05ac:0x8240 skip-reset"
    

6. Save the .vmx file.
7. Re-open Workstation/Fusion. The edited .vmx file is reloaded with the changes.
8. Start the virtual machine, and connect the device.
9. If the issue is not resolved, replace the quirks line added in Step 4 with one of these lines, in the order provided, and repeat Steps 5 to 8:

usb.quirks.device0 = "0xvid:0xpid skip-refresh"
usb.quirks.device0 = "0xvid:0xpid skip-setconfig"
usb.quirks.device0 = "0xvid:0xpid skip-reset, skip-refresh, skip-setconfig"

Notes:

• Use one of these lines at a time. If one does not work, replace it with another one in the list. Do not add more than one of these in the .vmx file at a time.
• The last line uses all three quirks in combination. Use this only if the other three lines do not work.

Refer this to see in detail.

There is a way to redirect JVM thread dump output on break signal to separate file with LogVMOutput diagnostic option:

-XX:+UnlockDiagnosticVMOptions -XX:+LogVMOutput -XX:LogFile=jvm.log

ORA-12154: TNS:could not resolve the connect identifier specified?

In case the TNS is not defined you can also try this one:

If you are using C#.net 2010 or other version of VS and oracle 10g express edition or lower version, and you make a connection string like this:

static string constr = @"Data Source=(DESCRIPTION=
    (ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=yourhostname )(PORT=1521)))
    (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=XE)));
    User Id=system ;Password=yourpasswrd"; 

After that you get error message ORA-12154: TNS:could not resolve the connect identifier specified then first you have to do restart your system and run your project.

And if Your windows is 64 bit then you need to install oracle 11g 32 bit and if you installed 11g 64 bit then you need to Install Oracle 11g Oracle Data Access Components (ODAC) with Oracle Developer Tools for Visual Studio version 11.2.0.1.2 or later from OTN and check it in Oracle Universal Installer Please be sure that the following are checked:

Oracle Data Provider for .NET 2.0

Oracle Providers for ASP.NET

Oracle Developer Tools for Visual Studio

Oracle Instant Client 

And then restart your Visual Studio and then run your project .... NOTE:- SYSTEM RESTART IS necessary TO SOLVE THIS TYPES OF ERROR.......

I liked the Xembly syntax, but it is not a statically typed API. You can get this with XMLBeam:

// Declare a projection
public interface Projection {

    @XBWrite("/root/order/@id")
    Projection setID(int id);

    @XBWrite("/root/order")
    Projection setValue(String value);
}

public static void main(String[] args) {
    // create a projector
    XBProjector projector = new XBProjector();

    // use it to create a projection instance
    Projection projection = projector.projectEmptyDocument(Projection.class);

    // You get a fluent API, with java types in parameters 
    projection.setID(553).setValue("$140.00");

    // Use the projector again to do IO stuff or create an XML-string
    projector.toXMLString(projection);
}

My experience is that this works great even when the XML gets more complicated. You can just decouple the XML structure from your java code structure.

You should put javascript tag in your html file. because browser load your webpage according to html flow, you should put your javascript file<script src="javascript/game.js"> after the <canvas>element tag. otherwise,if you put your javascript in the header of html.Browser load script first but it doesn't find the canvas. So your canvas doesn't work.

Set the horizontalPolicy & VerticalPolicy for the controls/widgets to "Preferred".

For anyone who make it in bigger scale, you might have also check how many file descriptors you have. It will throw this error if you ran out at bad moment.

UPDATE ANDROID 10 AND HIGHER

Start an activity from service (foreground or background) is no longer allowed.

There are still some restrictions that can be seen in the documentation

https://developer.android.com/guide/components/activities/background-starts

Right click on the project Configure > convert to Maven project

Then you can see all the Maven related Menu for you project.

The window is the actual global object.

The screen is the screen, it contains properties about the user's display.

The document is where the DOM is.

Just return the following:

return Unauthorized();

Surely you just need:

double seconds = milliseconds / 1000.0;

There's no need to manually do the two parts separately - you just need floating point arithmetic, which the use of 1000.0 (as a double literal) forces. (I'm assuming your milliseconds value is an integer of some form.)

Note that as usual with double, you may not be able to represent the result exactly. Consider using BigDecimal if you want to represent 100ms as 0.1 seconds exactly. (Given that it's a physical quantity, and the 100ms wouldn't be exact in the first place, a double is probably appropriate, but...)

Try this :

    new OutputStreamWriter( new FileOutputStream("Your_file_fullpath" ),Charset.forName("UTF8"))

I face the same problem and changing

 $cfg['Servers'][$i]['host'] = 'localhost';

to

 $cfg['Servers'][$i]['host'] = '127.0.0.1';

Solved this issue.

string MyConString = "Data Source='mysql7.000webhost.com';" +
"Port=3306;" +
"Database='a455555_test';" +
"UID='a455555_me';" +
"PWD='something';";

Or use a cast with split to uniform type of str

unique, counts = numpy.unique(str(a).split(), return_counts=True)

make it simple

private void dataGridView1_cellformatting(object sender,DataGridViewCellFormattingEventArgs e)
{
     var amount = (int)e.Value;

     // return if rowCount = 0
     if (this.dataGridView1.Rows.Count == 0)
         return;

     if (amount > 0)
         e.CellStyle.BackColor = Color.Green; 
     else
         e.CellStyle.BackColor = Color.Red;

}

take a look cell formatting

ExpressiveAnnotations gives you such a possibility:

[Required]
[AssertThat("Length(FieldA) + Length(FieldB) + Length(FieldC) + Length(FieldD) > 50")]
public string FieldA { get; set; }

@CemKalyoncu: Thanks for the great answer!

I also adapted it slightly to make it more like the Array.splice method (and took @Ates' note into consideration):

spliceString=function(string, index, numToDelete, char) {
      return string.substr(0, index) + char + string.substr(index+numToDelete);
   }

var myString="hello world!";
spliceString(myString,myString.lastIndexOf('l'),2,'mhole'); // "hello wormhole!"

Commonly when updating a column, we want to map an old value to a new value. Here's a way to do that in pyspark without UDF's:

# update df[update_col], mapping old_value --> new_value
from pyspark.sql import functions as F
df = df.withColumn(update_col,
    F.when(df[update_col]==old_value,new_value).
    otherwise(df[update_col])).

Have a look at Wikipedia:

Systems based on ASCII or a compatible character set use either LF (Line feed, '\n', 0x0A, 10 in decimal) or CR (Carriage return, '\r', 0x0D, 13 in decimal) individually, or CR followed by LF (CR+LF, 0x0D 0x0A). These characters are based on printer commands: The line feed indicated that one line of paper should feed out of the printer, and a carriage return indicated that the printer carriage should return to the beginning of the current line.

I don't have a windows box handy to try this but I think you can use a DataView and do something like so:

DataView view = new DataView(ds.Tables["MyTable"]);
view.RowFilter = "MyValue = 42"; // MyValue here is a column name

// Delete these rows.
foreach (DataRowView row in view)
{
  row.Delete();
}

I haven't tested this, though. You might give it a try.

I downloaded and extracted Crypto++ in C:\cryptopp. I used Visual Studio Express 2012 to build all the projects inside (as instructed in readme), and everything was built successfully. Then I made a test project in some other folder and added cryptolib as a dependency.

The conversion was probably not successful. The only thing that was successful was the running of VCUpgrade. The actual conversion itself failed but you don't know until you experience the errors you are seeing. For some of the details, see Visual Studio on the Crypto++ wiki.

Any ideas how to fix this?

To resolve your issues, you should download vs2010.zip if you want static C/C++ runtime linking (/MT or /MTd), or vs2010-dynamic.zip if you want dynamic C/C++ runtime linking (/MT or /MTd). Both fix the latent, silent failures produced by VCUpgrade.

vs2010.zip, vs2010-dynamic.zip and vs2005-dynamic.zip are built from the latest GitHub sources. As of this writing (JUN 1 2016), that's effectively pre-Crypto++ 5.6.4. If you are using the ZIP files with a down level Crypto++, like 5.6.2 or 5.6.3, then you will run into minor problems.

There are two minor problems I am aware. First is a rename of bench.cpp to bench1.cpp. Its error is either:

• C1083: Cannot open source file: 'bench1.cpp': No such file or directory
• LNK2001: unresolved external symbol "void __cdecl OutputResultOperations(char const *,char const *,bool,unsigned long,double)" (?OutputResultOperations@@YAXPBD0_NKN@Z)

The fix is to either (1) open cryptest.vcxproj in notepad, find bench1.cpp, and then rename it to bench.cpp. Or (2) rename bench.cpp to bench1.cpp on the filesystem. Please don't delete this file.

The second problem is a little trickier because its a moving target. Down level releases, like 5.6.2 or 5.6.3, are missing the latest classes available in GitHub. The missing class files include HKDF (5.6.3), RDRAND (5.6.3), RDSEED (5.6.3), ChaCha (5.6.4), BLAKE2 (5.6.4), Poly1305 (5.6.4), etc.

The fix is to remove the missing source files from the Visual Studio project files since they don't exist for the down level releases.

Another option is to add the missing class files from the latest sources, but there could be complications. For example, many of the sources subtly depend upon the latest config.h, cpu.h and cpu.cpp. The "subtlety" is you won't realize you are getting an under-performing class.

An example of under-performing class is BLAKE2. config.h adds compile time ARM-32 and ARM-64 detection. cpu.h and cpu.cpp adds runtime ARM instruction detection, which depends upon compile time detection. If you add BLAKE2 without the other files, then none of the detection occurs and you get a straight C/C++ implementation. You probably won't realize you are missing the NEON opportunity, which runs around 9 to 12 cycles-per-byte versus 40 cycles-per-byte or so for vanilla C/C++.

I have replaced the printf calls with calls to warning in the C-code now. It will be effective in the version 2.17.2 which should be available tomorrow night. Then you should be able to avoid the warnings with suppressWarnings() or any of the other above mentioned methods.

suppressWarnings({ your code })

Use the built-in isinstance() function.

import pandas as pd

def f(var):
    if isinstance(var, pd.DataFrame):
        print("do stuff")

Briefly, the error means that you can't use a static library to be linked w/ a dynamic one. The correct way is to have a libavcodec compiled into a .so instead of .a, so the other .so library you are trying to build will link well.

The shortest way to do so is to add --enable-shared at ./configure options. Or even you may try to disable shared (or static) libraries at all... you choose what is suitable for you!

It also happens when you have not give enough permissions(read and write) to your sock file!

Just add expected permission to your sock contained folder and your sock file:

 chmod ug+rw /path/to/your/
 chmod ug+rw /path/to/your/file.sock

Then have fun!

While there are IPv6 equivalents for the IPv4 address range, you can't convert all IPv6 addresses to IPv4 - there are more IPv6 addresses than there are IPv4 addresses.

The only sane way around this issue is to update your application to be able to understand and store IPv6 addresses.

DEMO.

For more information.

I am guessing there is a fundamental reason for the change, it isn't merely cosmetic to make the old interpretation clearer: that reason is concurrency. Unspecified order of elaboration is merely selection of one of several possible serial orderings, this is quite different to before and after orderings, because if there is no specified ordering, concurrent evaluation is possible: not so with the old rules. For example in:

f (a,b)

previously either a then b, or, b then a. Now, a and b can be evaluated with instructions interleaved or even on different cores.

A simple solution but it gets the job done, assigns a known length and precision and avoids the chance of going exponential format (which is a risk when you use %g):

// Since we are only interested in 3 decimal places, this function
// can avoid any potential miniscule floating point differences
// which can return false when using "=="
int DoubleEquals(double i, double j)
{
    return (fabs(i - j) < 0.000001);
}

void PrintMaxThreeDecimal(double d)
{
    if (DoubleEquals(d, floor(d)))
        printf("%.0f", d);
    else if (DoubleEquals(d * 10, floor(d * 10)))
        printf("%.1f", d);
    else if (DoubleEquals(d * 100, floor(d* 100)))
        printf("%.2f", d);
    else
        printf("%.3f", d);
}

Add or remove "elses" if you want a max of 2 decimals; 4 decimals; etc.

For example if you wanted 2 decimals:

void PrintMaxTwoDecimal(double d)
{
    if (DoubleEquals(d, floor(d)))
        printf("%.0f", d);
    else if (DoubleEquals(d * 10, floor(d * 10)))
        printf("%.1f", d);
    else
        printf("%.2f", d);
}

If you want to specify the minimum width to keep fields aligned, increment as necessary, for example:

void PrintAlignedMaxThreeDecimal(double d)
{
    if (DoubleEquals(d, floor(d)))
        printf("%7.0f", d);
    else if (DoubleEquals(d * 10, floor(d * 10)))
        printf("%9.1f", d);
    else if (DoubleEquals(d * 100, floor(d* 100)))
        printf("%10.2f", d);
    else
        printf("%11.3f", d);
}

You could also convert that to a function where you pass the desired width of the field:

void PrintAlignedWidthMaxThreeDecimal(int w, double d)
{
    if (DoubleEquals(d, floor(d)))
        printf("%*.0f", w-4, d);
    else if (DoubleEquals(d * 10, floor(d * 10)))
        printf("%*.1f", w-2, d);
    else if (DoubleEquals(d * 100, floor(d* 100)))
        printf("%*.2f", w-1, d);
    else
        printf("%*.3f", w, d);
}

This could be done using List::Util's first function:

use List::Util qw/first/;

my @array = qw/foo bar baz/;
print first { $_ eq 'bar' } @array;

Other functions from List::Util like max, min, sum also may be useful for you

I uninstall Only Android studio (keep the SDK and Emulator) and then reinstall it just android studio. took me 2 minutes and my android studio work again.

To me, handling exception can be seen as business rule. Obviously, the first approach is unacceptable. The second one is better one and it might be 100% correct way IF the context says so. Now, for example, you are developing an Outlook Addin. If you addin throws unhandled exception, the outlook user might now know it since the outlook will not destroy itself because of one plugin failed. And you have hard time to figure out what went wrong. Therefore, the second approach in this case, to me, it is a correct one. Beside logging the exception, you might decide to display error message to user - i consider it as a business rule.

This problem appear if two software use same port
generally Android studio use the port 5037
try to close the port by cmd according to your operating system
then reboot your Android studio or your Eclipse

If you want the biggest pt value for a subject, you could simply use:

   pt_max = as.data.frame(aggregate(pt~Subject, group, max))

Let’s look at how to filter a built-in JDK List and a MutableList using Eclipse Collections.

List<Integer> jdkList = Arrays.asList(1, 2, 3, 4, 5);
MutableList<Integer> ecList = Lists.mutable.with(1, 2, 3, 4, 5);

If you wanted to filter the numbers less than 3, you would expect the following outputs.

List<Integer> selected = Lists.mutable.with(1, 2);
List<Integer> rejected = Lists.mutable.with(3, 4, 5);

Here’s how you can filter using a Java 8 lambda as the Predicate.

Assert.assertEquals(selected, Iterate.select(jdkList, each -> each < 3));
Assert.assertEquals(rejected, Iterate.reject(jdkList, each -> each < 3));

Assert.assertEquals(selected, ecList.select(each -> each < 3));
Assert.assertEquals(rejected, ecList.reject(each -> each < 3));

Here’s how you can filter using an anonymous inner class as the Predicate.

Predicate<Integer> lessThan3 = new Predicate<Integer>()
{
    public boolean accept(Integer each)
    {
        return each < 3;
    }
};

Assert.assertEquals(selected, Iterate.select(jdkList, lessThan3));
Assert.assertEquals(selected, ecList.select(lessThan3));

Here are some alternatives to filtering JDK lists and Eclipse Collections MutableLists using the Predicates factory.

Assert.assertEquals(selected, Iterate.select(jdkList, Predicates.lessThan(3)));
Assert.assertEquals(selected, ecList.select(Predicates.lessThan(3)));

Here is a version that doesn't allocate an object for the predicate, by using the Predicates2 factory instead with the selectWith method that takes a Predicate2.

Assert.assertEquals(
    selected, ecList.selectWith(Predicates2.<Integer>lessThan(), 3));

Sometimes you want to filter on a negative condition. There is a special method in Eclipse Collections for that called reject.

Assert.assertEquals(rejected, Iterate.reject(jdkList, lessThan3));
Assert.assertEquals(rejected, ecList.reject(lessThan3));

The method partition will return two collections, containing the elements selected by and rejected by the Predicate.

PartitionIterable<Integer> jdkPartitioned = Iterate.partition(jdkList, lessThan3);
Assert.assertEquals(selected, jdkPartitioned.getSelected());
Assert.assertEquals(rejected, jdkPartitioned.getRejected());

PartitionList<Integer> ecPartitioned = gscList.partition(lessThan3);
Assert.assertEquals(selected, ecPartitioned.getSelected());
Assert.assertEquals(rejected, ecPartitioned.getRejected());

Note: I am a committer for Eclipse Collections.

I've checked your source code and find to change to yellow you need to adds the yellow background color to : #left-padding, #right-padding, html, #hd, #main and #yui-main.

Hope it's what you wanted. See ya

This is what helped me:

1. Create a new branch with the existing one. Let's call the existing one branch_old and new as branch_new.

2. Reset branch_new to a stable state, when you did not have any problem commit at all. For example, to put it at your local master's level do the following:

   git reset —hard master git push —force origin

3. cherry-pick the commits from branch_old into branch_new

4. git push

Assuming you just need to reverse an indexed array (not associative or multidimensional) a simple for loop would suffice:

$fruits = ['bananas', 'apples', 'pears'];
for($i = count($fruits)-1; $i >= 0; $i--) {
    echo $fruits[$i] . '<br>';
} 

The command, that can be executed:

svn up --username newUsername

Works perfectly ;)

P.S. Just a hint: "--username" option can be executed on any "svn" command, not just update.

We have M2_HOME,MAVEN_HOME,M3_HOME all are available in market
Previously M2_HOME is the only environment variable used by all as a standard.
But,due latest releases the MAVEN_Home came as standard but some old tools are still trying to find only M2_HOME
so we should have both M2_HOME,MAVEN_HOME to sustain with old and new tools.
M2_HOME can be used for both as well

Use "External data" from Excel. It can use ODBC connection to fetch data from external source: Data/Get External Data/New Database Query

That way, even if the data in the database changes, you can easily refresh.

Go to

C:\drive\xampp(where xampp installed)

simply find php.ini file then in the file search

post_max_size=XXM
upload_max_size=XXM

Change with this code

post_max_size=100M
upload_max_filesize=100M

Don't forget to restart the xampp

I did not find where the .rnd file is so I ran the cmd as administrator and it worked like a charm.

As an alternative, you can install 7.1 version of mcrypt and create a symbolic link to it:

Install php7.1-mcrypt:

sudo apt install php7.1-mcrypt

Create a symbolic link:

sudo ln -s /etc/php/7.1/mods-available/mcrypt.ini /etc/php/7.2/mods-available

After enabling mcrypt by sudo phpenmod mcrypt, it gets available.

You can try adding a question mark as below. This worked for me.

 componentWillReceiveProps(nextProps) {
    this.setState({
        title: nextProps?.blog?.title,
        body: nextProps?.blog?.content
     })
    }

Best solution to this is css/html: Make a div to wrap your elements in, if you dont have it already And set it to position fixed and overflow hidden. Optional, set height and width to 100% if you want it to fill the whole screen and nothing but the whole screen

#wrapper{_x000D_
  height: 100%;_x000D_
  width: 100%;_x000D_
  position: fixed;_x000D_
  overflow: hidden;_x000D_
}

<div id="wrapper">_x000D_
  <p>All</p>_x000D_
  <p>Your</p>_x000D_
  <p>Elements</p>_x000D_
</div>

First of all select report file with rdlc extension and then go to View > Report Data

As far as I have understood your question, you have listed two issues.

PROBLEM 1:

You are not able to execute the Python scripts by double clicking the Python file in Windows.

REASON:

The script runs too fast to be seen by the human eye.

SOLUTION:

Add input() in the bottom of your script and then try executing it with double click. Now the cmd will be open until you close it.

EXAMPLE:

print("Hello World")
input()

PROBLEM 2:

./ issue

SOLUTION:

Use Tab to autocomplete the filenames rather than manually typing the filename with ./ autocomplete automatically fills all this for you.

USAGE:

CD into the directory in which .py files are present and then assume the filename is test.py then type python te and then press Tab, it will be automatically converted to python ./test.py.

If you are facing an error with the folder, such as src/test/java or src/test/resources, just do a right click on the folder and then create a a new folder with the name being src/test/java. This should solve your problem.

In my case it helps if you don't install the x86 version over the x64 version... DOH!!!

<form id = "uploadForm" name = "uploadForm" enctype="multipart/form-data">
    <label for="uploadFile">Upload Your File</label>
     <input type="file" name="uploadFile" id="uploadFile">                  
</form>
<script>
    $('#uploadFile').change(function(){
        var fileName = this.files[0].name;
        var fileSize = this.files[0].size;
        var fileType = this.files[0].type;
        alert('FileName : ' + fileName + '\nFileSize : ' + fileSize + ' bytes');
    });
</script>

Note: To get the uploading file name means then use jquery val() method.

For Ex:

var fileName = $('#uploadFile').val();

I checked this above code before post, it works perfectly.!

According to the documentation:

newshape : int or tuple of ints

The new shape should be compatible with the original shape. If an integer, then the result will be a 1-D array of that length. One shape dimension can be -1. In this case, the value is inferred from the length of the array and remaining dimensions.

1. Down the apache server by running below in putty cd $ADMIN_SCRIPTS_HOME ./adstpall.sh

In hibernate you can use this code to easily map your native query.

As Jon Skeet mentioned you can do it with a List<Track> instead. The Track class would look something like this:

public class Track {
    public int TrackID { get; set; }
    public string Name { get; set; }
    public string Artist { get; set; }
    public string Album { get; set; }
    public int PlayCount { get; set; }
    public int SkipCount { get; set; }
}

And to create a track list as a List<Track> you simply do this:

var trackList = new List<Track>();

Adding tracks can be as simple as this:

trackList.add( new Track {
    TrackID = 1234,
    Name = "I'm Gonna Be (500 Miles)",
    Artist = "The Proclaimers",
    Album = "Finest",
    PlayCount = 10,
    SkipCount = 1
});

Accessing tracks can be done with the indexing operator:

Track firstTrack = trackList[0];

Hope this helps.

This is how I manage to "download" it:

1. Use inspect-element to identify the URL of the M3U playlist file
2. Download the M3U file
3. Use VLC to read the M3U file, stream and convert the video to MP4

In Firefox the M3U file appeared as of type application/vnd.apple.mpegurl

The contents of the M3U file would look like:

Open VLC medial player and use the Media => Convert option. Use your (saved) M3U file as the source:

There's public static class AbstractMap.SimpleEntry<K,V>. Don't let the Abstract part of the name mislead you: it is in fact NOT an abstract class (but its top-level AbstractMap is).

The fact that it's a static nested class means that you DON'T need an enclosing AbstractMap instance to instantiate it, so something like this compiles fine:

Map.Entry<String,Integer> entry =
    new AbstractMap.SimpleEntry<String, Integer>("exmpleString", 42);

As noted in another answer, Guava also has a convenient static factory method Maps.immutableEntry that you can use.

You said:

I can't use Map.Entry itself because apparently it's a read-only object that I can't instantiate new instanceof

That's not entirely accurate. The reason why you can't instantiate it directly (i.e. with new) is because it's an interface Map.Entry.

Caveat and tip

As noted in the documentation, AbstractMap.SimpleEntry is @since 1.6, so if you're stuck to 5.0, then it's not available to you.

To look for another known class that implements Map.Entry, you can in fact go directly to the javadoc. From the Java 6 version

Interface Map.Entry

All Known Implementing Classes:

• AbstractMap.SimpleEntry, AbstractMap.SimpleImmutableEntry

Unfortunately the 1.5 version does not list any known implementing class that you can use, so you may have be stuck with implementing your own.

create .properties file in classpath of your project and add path configuration in xml`<context:property-placeholder location="classpath*:/*.properties" />`

in servlet-context.xml after that u can directly use your file everywhere

[+*?.] Most special characters have no meaning inside the square brackets. This expression matches any of +, *, ? or the dot.

Or simple extension class like this:

public static class CollectionExtension
{
    private static Random rng = new Random();

    public static T RandomElement<T>(this IList<T> list)
    {
        return list[rng.Next(list.Count)];
    }

    public static T RandomElement<T>(this T[] array)
    {
        return array[rng.Next(array.Length)];
    }
}

Then just call:

myList.RandomElement();

Works for arrays as well.

I would avoid calling OrderBy() as it can be expensive for larger collections. Use indexed collections like List<T> or arrays for this purpose.

There is not only 1 %SystemRoot%\System32 on Windows x64. There are 2 such directories.

The real %SystemRoot%\System32 directory is for 64-bit applications. This directory contains a 64-bit cmd.exe.

But there is also %SystemRoot%\SysWOW64 for 32-bit applications. This directory is used if a 32-bit application accesses %SystemRoot%\System32. It contains a 32-bit cmd.exe.

32-bit applications can access %SystemRoot%\System32 for 64-bit applications by using the alias %SystemRoot%\Sysnative in path.

For more details see the Microsoft documentation about File System Redirector.

So the subdirectory run was created either in %SystemRoot%\System32 for 64-bit applications and 32-bit cmd is run for which this directory does not exist because there is no subdirectory run in %SystemRoot%\SysWOW64 which is %SystemRoot%\System32 for 32-bit cmd.exe or the subdirectory run was created in %SystemRoot%\System32 for 32-bit applications and 64-bit cmd is run for which this directory does not exist because there is no subdirectory run in %SystemRoot%\System32 as this subdirectory exists only in %SystemRoot%\SysWOW64.

The following code could be used at top of the batch file in case of subdirectory run is in %SystemRoot%\System32 for 64-bit applications:

@echo off
set "SystemPath=%SystemRoot%\System32"
if not "%ProgramFiles(x86)%" == "" if exist %SystemRoot%\Sysnative\* set "SystemPath=%SystemRoot%\Sysnative"

Every console application in System32\run directory must be executed with %SystemPath% in the batch file, for example %SystemPath%\run\YourApp.exe.

How it works?

There is no environment variable ProgramFiles(x86) on Windows x86 and therefore there is really only one %SystemRoot%\System32 as defined at top.

But there is defined the environment variable ProgramFiles(x86) with a value on Windows x64. So it is additionally checked on Windows x64 if there are files in %SystemRoot%\Sysnative. In this case the batch file is processed currently by 32-bit cmd.exe and only in this case %SystemRoot%\Sysnative needs to be used at all. Otherwise %SystemRoot%\System32 can be used also on Windows x64 as when the batch file is processed by 64-bit cmd.exe, this is the directory containing the 64-bit console applications (and the subdirectory run).

Note: %SystemRoot%\Sysnative is not a directory! It is not possible to cd to %SystemRoot%\Sysnative or use if exist %SystemRoot%\Sysnative or if exist %SystemRoot%\Sysnative\. It is a special alias existing only for 32-bit executables and therefore it is necessary to check if one or more files exist on using this path by using if exist %SystemRoot%\Sysnative\cmd.exe or more general if exist %SystemRoot%\Sysnative\*.

np.fromfile() has a sep= keyword argument:

Separator between items if file is a text file. Empty (“”) separator means the file should be treated as binary. Spaces (” ”) in the separator match zero or more whitespace characters. A separator consisting only of spaces must match at least one whitespace.

The default value of sep="" means that np.fromfile() tries to read it as a binary file rather than a space-separated text file, so you get nonsense values back. If you use np.fromfile('markers.txt', sep=" ") you will get the result you are looking for.

However, as others have pointed out, np.loadtxt() is the preferred way to convert text files to numpy arrays, and unless the file needs to be human-readable it is usually better to use binary formats instead (e.g. np.load()/np.save()).

Concise version of the sed command:

sed -i s/$/:80/ file.txt

Explanation:

• sed stream editor
  • -i in-place (edit file in place)
  • s substitution command
  • /replacement_from_reg_exp/replacement_to_text/ statement
  • $ matches the end of line (replacement_from_reg_exp)
  • :80 text you want to add at the end of every line (replacement_to_text)
• file.txt the file name

If you want to close it you can either hide it or remove it from the page. To hide it you would do some javascript like:

this.parentNode.style.display = 'none';

To remove it you use removeChild

this.parentNode.parentNode.removeChild(this.parentNode);

If you had a library like jQuery included then hiding or removing the div would be slightly easier:

$(this).parent().hide();
$(this).parent().remove();

One other thing, as your img is in an anchor the onclick event on the anchor is going to fire as well. As the href is set to # then the page will scroll back to the top of the page. Generally it is good practice that if you want a link to do something other than go to its href you should set the onclick event to return false;

Put the classname into a variable first:

$classname=$var.'Class';

$bar=new $classname("xyz");

This is often the sort of thing you'll see wrapped up in a Factory pattern.

I did copy the .classpath and .project from another project and adjusted the values properly.

Close the project before editing those files, when you are sure they reflect the reality (your reality anyway), re-open the project in Eclipse.

The workspace is rebuilt and all should work from then on.

Looks like it could be throwing the error on the empty data row, have you tried to just make sure itemDate isn't empty before you run the CDate() function? I think this might be your problem.

This worked for me:

find /A -type d -exec chmod 0755 {} \;
find /A -type f -exec chmod 0644 {} \;

For boolean logic, use & and |.

np.random.seed(0)
df = pd.DataFrame(np.random.randn(5,3), columns=list('ABC'))

>>> df
          A         B         C
0  1.764052  0.400157  0.978738
1  2.240893  1.867558 -0.977278
2  0.950088 -0.151357 -0.103219
3  0.410599  0.144044  1.454274
4  0.761038  0.121675  0.443863

>>> df.loc[(df.C > 0.25) | (df.C < -0.25)]
          A         B         C
0  1.764052  0.400157  0.978738
1  2.240893  1.867558 -0.977278
3  0.410599  0.144044  1.454274
4  0.761038  0.121675  0.443863

To see what is happening, you get a column of booleans for each comparison, e.g.

df.C > 0.25
0     True
1    False
2    False
3     True
4     True
Name: C, dtype: bool

When you have multiple criteria, you will get multiple columns returned. This is why the join logic is ambiguous. Using and or or treats each column separately, so you first need to reduce that column to a single boolean value. For example, to see if any value or all values in each of the columns is True.

# Any value in either column is True?
(df.C > 0.25).any() or (df.C < -0.25).any()
True

# All values in either column is True?
(df.C > 0.25).all() or (df.C < -0.25).all()
False

One convoluted way to achieve the same thing is to zip all of these columns together, and perform the appropriate logic.

>>> df[[any([a, b]) for a, b in zip(df.C > 0.25, df.C < -0.25)]]
          A         B         C
0  1.764052  0.400157  0.978738
1  2.240893  1.867558 -0.977278
3  0.410599  0.144044  1.454274
4  0.761038  0.121675  0.443863

For more details, refer to Boolean Indexing in the docs.

To use the tuple you need to do the following, in the view change the model to:

@model Tuple<Person,Order>

to use @html methods you need to do the following i.e:

@Html.DisplayNameFor(tuple => tuple.Item1.PersonId)

or

@Html.ActionLink("Edit", "Edit", new { id=Model.Item1.Id }) |

Item1 indicates the first parameter passed to the Tuple method and you can use Item2 to access the second model and so on.

in your controller you need to create a variable of type Tuple and then pass it to the view:

    public ActionResult Details(int id = 0)
    {
        Person person = db.Persons.Find(id);
        if (person == null)
        {
            return HttpNotFound();
        }
        var tuple = new Tuple<Person, Order>(person,new Order());

        return View(tuple);
    }

Ok I have found a solution. The problem is that the site uses SSLv3. And I know that there are some problems in the openssl module. Some time ago I had the same problem with the SSL versions.

<?php
function getSSLPage($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSLVERSION,3); 
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

var_dump(getSSLPage("https://eresearch.fidelity.com/eresearch/evaluate/analystsOpinionsReport.jhtml?symbols=api"));
?>

When you set the SSL Version with curl to v3 then it works.

Edit:

Another problem under Windows is that you don't have access to the certificates. So put the root certificates directly to curl.

http://curl.haxx.se/docs/caextract.html

here you can download the root certificates.

curl_setopt($ch, CURLOPT_CAINFO, __DIR__ . "/certs/cacert.pem");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);

Then you can use the CURLOPT_SSL_VERIFYPEER option with true otherwise you get an error.

For what it's worth: I just had the same problem, after editing the nginx.conf file. I tried and tried restarting it by commanding sudo nginx restart and various other commands. None of them produced any output. Commanding sudo nginx -t to check the configuration file gave the output sudo: nginx: command not found, which was puzzling. I was starting to think there were problems with the path.

Finally, I logged in as root (sudo su) and commanded sudo nginx restart. Now, the command displayed an error message concerning the configuration file. After fixing that, it restarted successfully.

There is no standard assert in JavaScript itself. Perhaps you're using some library that provides one; for instance, if you're using Node.js, perhaps you're using the assertion module. (Browsers and other environments that offer a console implementing the Console API provide console.assert.)

The usual meaning of an assert function is to throw an error if the expression passed into the function is false; this is part of the general concept of assertion checking. Usually assertions (as they're called) are used only in "testing" or "debug" builds and stripped out of production code.

Suppose you had a function that was supposed to always accept a string. You'd want to know if someone called that function with something that wasn't a string (without having a type checking layer like TypeScript or Flow). So you might do:

assert(typeof argumentName === "string");

...where assert would throw an error if the condition were false.

A very simple version would look like this:

function assert(condition, message) {
    if (!condition) {
        throw message || "Assertion failed";
    }
}

Better yet, make use of the Error object, which has the advantage of collecting a stack trace and such:

function assert(condition, message) {
    if (!condition) {
        throw new Error(message || "Assertion failed");
    }
}

This will let Git authenticate on HTTPS using .netrc:

• The file should be named _netrc and located in c:\Users\<username>.
• You will need to set an environment variable called HOME=%USERPROFILE% (set system-wide environment variables using the System option in the control panel. Depending on the version of Windows, you may need to select "Advanced Options".).
• The password stored in the _netrc file cannot contain spaces (quoting the password will not work).

Well try ini_set('memory_limit', '256M');

134217728 bytes = 128 MB

Or rewrite the code to consume less memory.

You can hide it :

html {
  overflow:   scroll;
}
::-webkit-scrollbar {
    width: 0px;
    background: transparent; /* make scrollbar transparent */
}

For further information, see : Hide scroll bar, but while still being able to scroll

I got this error too, but my problem was that I was using an older version of GACUTIL.EXE.

Once I had the correct GACUTIL for the latest .NET version installed, it worked fine.

The error is misleading because it makes it look like it's the DLL you're trying to register that incorrect.

firstOrCreate() checks for all the arguments to be present before it finds a match. If not all arguments match, then a new instance of the model will be created.

If you only want to check on a specific field, then use firstOrCreate(['field_name' => 'value']) with only one item in the array. This will return the first item that matches, or create a new one if not matches are found.

The difference between firstOrCreate() and firstOrNew():

• firstOrCreate() will automatically create a new entry in the database if there is not match found. Otherwise it will give you the matched item.
• firstOrNew() will give you a new model instance to work with if not match was found, but will only be saved to the database when you explicitly do so (calling save() on the model). Otherwise it will give you the matched item.

Choosing between one or the other depends on what you want to do. If you want to modify the model instance before it is saved for the first time (e.g. setting a name or some mandatory field), you should use firstOrNew(). If you can just use the arguments to immediately create a new model instance in the database without modifying it, you can use firstOrCreate().

I checked on my side by just adding '1.0' and it start working

tex.delete('1.0', END)

you can also try this

If you don't have control those files, as those files can be part of other projects and you are not authorized to make any changes, then you can bypass those errors in eclipse by going, Preferences --> XML --> XML Files --> Validation --> Referenced file contains errors --> choose Ignore option.

And let project get's validated, the error message will disappear.

I usually manually set the port that I am listening on in the app.js file (assuming you are using express.js

var server = app.listen(8080, function() {
    console.log('Ready on port %d', server.address().port);
});

This will log Ready on port 8080 to your console.

You can also use breakpoints. Assuming the value you want is defined within the scope of your breakpoint you have 3 options:

print it in console doing:

po some_paramter

Bare in mind in objective-c for properties you can't use self.

po _someProperty
po self.someProperty // would not work

po stands for print object.

Java Language Specification defines E1 op= E2 to be equivalent to E1 = (T) ((E1) op (E2)) where T is a type of E1 and E1 is evaluated once.

That's a technical answer, but you may be wondering why that's a case. Well, let's consider the following program.

public class PlusEquals {
    public static void main(String[] args) {
        byte a = 1;
        byte b = 2;
        a = a + b;
        System.out.println(a);
    }
}

What does this program print?

Did you guess 3? Too bad, this program won't compile. Why? Well, it so happens that addition of bytes in Java is defined to return an int. This, I believe was because the Java Virtual Machine doesn't define byte operations to save on bytecodes (there is a limited number of those, after all), using integer operations instead is an implementation detail exposed in a language.

But if a = a + b doesn't work, that would mean a += b would never work for bytes if it E1 += E2 was defined to be E1 = E1 + E2. As the previous example shows, that would be indeed the case. As a hack to make += operator work for bytes and shorts, there is an implicit cast involved. It's not that great of a hack, but back during the Java 1.0 work, the focus was on getting the language released to begin with. Now, because of backwards compatibility, this hack introduced in Java 1.0 couldn't be removed.

MySQL prior to version 5 did not allow aggregate functions in ORDER BY clauses.

You can get around this limit with the deprecated syntax:

SELECT COUNT(id), `Tag` from `images-tags`
GROUP BY `Tag`
ORDER BY 1 DESC
LIMIT 20

1, since it's the first column you want to group on.

There is a nice script available on http://www.reddyss.com/SQLDownloads.aspx

To be able to use it on any database you can create it like in: http://nickstips.wordpress.com/2010/10/18/sql-making-a-stored-procedure-available-to-all-databases/

Not sure if there is other way.

To use it then use something like this:

use name_of_database

EXEC spUtil_SearchText 'value_searched', 0, 0

Try setting core.autocrlf value like this :

git config --global core.autocrlf true

curl -O -L  https://sourceforge.net/projects/sshpass/files/sshpass/1.06/sshpass-1.06.tar.gz && tar xvzf sshpass-1.06.tar.gz
cd sshpass-1.06/
./configure
sudo make install

You can use the DataGridViewCell.Value Property to retrieve the value stored in a particular cell.

So to retrieve the value of the 'first' selected Cell and display in a MessageBox, you can:

MessageBox.Show(dataGridView1.SelectedCells[0].Value.ToString());

The above probably isn't exactly what you need to do. If you provide more details we can provide better help.

The problem is the import of ProjectsListComponent in your ProjectsModule. You should not import that, but add it to the export array, if you want to use it outside of your ProjectsModule.

Other issues are your project routes. You should add these to an exportable variable, otherwise it's not AOT compatible. And you should -never- import the BrowserModule anywhere else but in your AppModule. Use the CommonModule to get access to the *ngIf, *ngFor...etc directives:

@NgModule({
  declarations: [
     ProjectsListComponent
  ],
  imports: [
    CommonModule,
    RouterModule.forChild(ProjectRoutes)
  ],
  exports: [
     ProjectsListComponent
  ]
})

export class ProjectsModule {}

project.routes.ts

export const ProjectRoutes: Routes = [
      { path: 'projects', component: ProjectsListComponent }

Discord doesn't allow colored text. Though, currently, you have two options to "mimic" colored text.

Option #1 (Markdown code-blocks)

Discord supports Markdown and uses highlight.js to highlight code-blocks. Some programming languages have specific color outputs from highlight.js and can be used to mimic colored output.

To use code-blocks, send a normal message in this format (Which follows Markdown's standard format).

```language
message
```

Languages that currently reproduce nice colors: prolog (red/orange), css (yellow).

Option #2 (Embeds)

Discord now supports Embeds and Webhooks, which can be used to display colored blocks, they also support markdown. For documentation on how to use Embeds, please read your lib's documentation.

Spark 2.2+

Spark 2.2 introduces typedLit to support Seq, Map, and Tuples (SPARK-19254) and following calls should be supported (Scala):

import org.apache.spark.sql.functions.typedLit

df.withColumn("some_array", typedLit(Seq(1, 2, 3)))
df.withColumn("some_struct", typedLit(("foo", 1, 0.3)))
df.withColumn("some_map", typedLit(Map("key1" -> 1, "key2" -> 2)))

Spark 1.3+ (lit), 1.4+ (array, struct), 2.0+ (map):

The second argument for DataFrame.withColumn should be a Column so you have to use a literal:

from pyspark.sql.functions import lit

df.withColumn('new_column', lit(10))

If you need complex columns you can build these using blocks like array:

from pyspark.sql.functions import array, create_map, struct

df.withColumn("some_array", array(lit(1), lit(2), lit(3)))
df.withColumn("some_struct", struct(lit("foo"), lit(1), lit(.3)))
df.withColumn("some_map", create_map(lit("key1"), lit(1), lit("key2"), lit(2)))

Exactly the same methods can be used in Scala.

import org.apache.spark.sql.functions.{array, lit, map, struct}

df.withColumn("new_column", lit(10))
df.withColumn("map", map(lit("key1"), lit(1), lit("key2"), lit(2)))

To provide names for structs use either alias on each field:

df.withColumn(
    "some_struct",
    struct(lit("foo").alias("x"), lit(1).alias("y"), lit(0.3).alias("z"))
 )

or cast on the whole object

df.withColumn(
    "some_struct", 
    struct(lit("foo"), lit(1), lit(0.3)).cast("struct<x: string, y: integer, z: double>")
 )

It is also possible, although slower, to use an UDF.

Note:

The same constructs can be used to pass constant arguments to UDFs or SQL functions.

In my case, I left out wrapper sub folder while copying gradle folder and got the same error.

Could not find or load main class org.gradle.wrapper.GradleWrapperMain

make sure you have the correct folder structure if you copy wrapper from other location.

+-- build.gradle
+-- gradle
¦   +-- wrapper
¦       +-- gradle-wrapper.jar
¦       +-- gradle-wrapper.properties
+-- gradlew
+-- gradlew.bat
+-- settings.gradle

You can try CustomScrollView. Put your CustomScrollView inside Column Widget.

Just for example -

class App extends StatelessWidget {

 App({Key key}): super(key: key);

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: AppBar(
          title: const Text('AppBar'),
      ),
      body: new Container(
          constraints: BoxConstraints.expand(),
          decoration: new BoxDecoration(
            image: new DecorationImage(
              alignment: Alignment.topLeft,
              image: new AssetImage('images/main-bg.png'),
              fit: BoxFit.cover,
            )
          ),
          child: new Column(
            children: <Widget>[               
              Expanded(
                child: new CustomScrollView(
                  scrollDirection: Axis.vertical,
                  shrinkWrap: false,
                  slivers: <Widget>[
                    new SliverPadding(
                      padding: const EdgeInsets.symmetric(vertical: 0.0),
                      sliver: new SliverList(
                        delegate: new SliverChildBuilderDelegate(
                          (context, index) => new YourRowWidget(),
                          childCount: 5,
                        ),
                      ),
                    ),
                  ],
                ),
              ),
            ],
          )),
    );
  }
}

In above code I am displaying a list of items ( total 5) in CustomScrollView. YourRowWidget widget gets rendered 5 times as list item. Generally you should render each row based on some data.

You can remove decoration property of Container widget, it is just for providing background image.

The global type Function serves this purpose.

Additionally, if you intend to invoke this callback with 0 arguments and will ignore its return value, the type () => void matches all functions taking no arguments.

Update with details and improvements.

The answer and question here has way too many updoots not to mention the only-slightly more complex yet best-practice method:

Solution to your question

interface Easy_Fix_Solution {
    title: string;
    callback: Function;
}

NOTE: Please do not use Function as you most likely do not want any callback function. It's okay to be a little specific.

Improvement to that solution

interface Safer_Easy_Fix {
    title: string;
    callback: () => void;
}
interface Alternate_Syntax_4_Safer_Easy_Fix {
    title: string;
    callback(): void;
}

NOTE: The original author is correct, accepting no arguments and returning void is better.. it's much safer, it tells the consumer of your interface that you will not be doing anything with their return value, and that you will not be passing them any parameters.

And better yet Use generics. This interface would also work for the same () => void function types mentioned before.

interface Better_still_safe_but_way_more_flexible_fix {
    title: string;
    callback: <T = unknown, R = unknown>(args?: T) => R;
}
interface Alternate_Syntax_4_Better_still_safe_but_way_more_flexible_fix {
    title: string;
    callback<T = unknown, R = unknown>(args?: T): R;
}

NOTE: If you aren't 100% sure about the callback signature right now, please choose the void option above, or this generic option if you think you may extend functionality going forward. Callbacks usually receive some arguments of some sort, and sometimes the callback orchestrator even does something with the return value.

And a slightly more advanced usecase you shouldn't use unless you need it

This allows any number of arguments, of any type in T.

More details here.

interface Alternate_Syntax_4_Advanced {
    title: string;
    callback<T extends unknown[], R = unknown>(...args?: T): R;
}

I prefer approach of Tommy Carlier, but with a little change.

foreach (DataColumn column in row.Table.Columns)
    if (!row.IsNull(column))
      return false;

  return true;

I suppose this approach looks more simple and bright.

document.all() is a non-standard way of accessing DOM elements. It's been deprecated from a few browsers. It gives you access to all sub elements on your document.

document.getElementById() is a standard and fully supported. Each element have a unique id on the document.

If you have:

<div id="testing"></div>

Using

document.getElementById("testing"); 

Will have access to that specific div.

you need to take out the quotes:

soda = a + b

(You want to refer to the variables a and b, not the strings "a" and "b")

COUNTIF function will only count cells that contain numbers in your specified range.

COUNTA(range) will count all values in the list of arguments. Text entries and numbers are counted, even when they contain an empty string of length 0.

Example: Function in A7 =COUNTA(A1:A6)

Range:

A1 a

A2 b

A3 banana

A4 42

A5

A6

A7 4 -> result

Google spreadsheet function list contains a list of all available functions for future reference https://support.google.com/drive/table/25273?hl=en.

Use the following code:

function hide {
document.getElementById('div').style.display = "none";
}
function show {
document.getElementById('div').style.display = "block";
}

Values highlighted that I mean:

For those using homebrew you might fix this with:

$ brew link mysql

I also had this issue with my Android app depending on some of my own Android libraries (using Android Studio 3.0 and 3.1.1).

Whenever I updated a lib and go back to the app, triggering a Gradle Sync, Android Studio was not able to detect the code changes I made to the lib. Compilation worked fine, but Android Studio showed red error lines on some code using the lib.

After investigating, I found that it's because gradle keeps pointing to an old compiled version of my libs. If you go to yourProject/.idea/libraries/ you'll see a list of xml files that contains the link to the compiled version of your libs. These files starts with Gradle__artifacts_*.xml (where * is the name of your libs).

So in order for Android Studio to take the latest version of your libs, you need to delete these Gradle__artifacts_*.xml files, and Android Studio will regenerate them, pointing to the latest compiled version of your libs.

If you don't want to do that manually every time you click on "Gradle sync" (who would want to do that...), you can add this small gradle task in the build.gradle file of your app.

task deleteArtifacts {
    doFirst {
        File librariesFolderPath = file(getProjectDir().absolutePath + "/../.idea/libraries/")
        File[] files = librariesFolderPath.listFiles({ File file -> file.name.startsWith("Gradle__artifacts_") } as FileFilter)

        for (int i = 0; i < files.length; i++) {
            files[i].delete()
        }
    }
}

And in order for your app to always execute this task before doing a gradle sync, you just need to go to the Gradle window, then find the "deleteArtifacts" task under yourApp/Tasks/other/, right click on it and select "Execute Before Sync" (see below).

Now, every time you do a Gradle sync, Android Studio will be forced to use the latest version of your libs.

If the intention is adding the local/working copy to SVN, I used to do it the following way.

Note: I use the TortoiseSVN client and these steps assume that you already have the TortoiseSVN client installed.

1. I have a project (Test-4.2.2) in my local. I want to upload/add it to an SVN repository.
2. Using the TortoiseSVN repo-browser, I created an empty directory, "Test-4.2.2"
3. In my local I renamed the existing "Test-4.2.2" directory to "Test-4.2.2.1" (temporary)
4. Checkout the empty "Test-4.2.2" from SVN to your local
5. Copy all the sub-directories under 4.2.2.1 to this checkout directory 4.2.2
6. Now, right click "Test-4.2.2" and commit.
7. Delete the temp folder, "Test-4.2.2.1"

if you hit the "back" button it usually tends to stick, what you can do is when the form is submitted clear the element then before it goes to the next page but after doing with the element what you need to.

    $('#shares').keyup(function(){
                payment = 0;
                calcTotal();
                gtotal = ($('#shares').val() * 1) + payment;
                gtotal = gtotal.toFixed(2);
                $('#shares').val('');
                $("p.total").html("Total Payment: <strong>" + gtotal + "</strong>");
            });

Yes, ensure is called in any circumstances. For more information see "Exceptions, Catch, and Throw" of the Programming Ruby book and search for "ensure".

I have found a solution in Python that is working well !

from math import atan2,degrees

def GetAngleOfLineBetweenTwoPoints(p1, p2):
    return degrees(atan2(p2 - p1, 1))

print GetAngleOfLineBetweenTwoPoints(1,3)

Creating a virtual environment for Jupyter Notebooks

A minimal Python install is

sudo apt install python3.7 python3.7-venv python3.7-minimal python3.7-distutils python3.7-dev python3.7-gdbm python3-gdbm-dbg python3-pip

Then you can create and use the environment

/usr/bin/python3.7 -m venv test
cd test
source test/bin/activate
pip install jupyter matplotlib seaborn numpy pandas scipy
# install other packages you need with pip/apt
jupyter notebook
deactivate

You can make a kernel for Jupyter with

ipython3 kernel install --user --name=test

For those trying to make the connection between SNR and a normal random variable generated by numpy:

[1] , where it's important to keep in mind that P is average power.

Or in dB:
[2]

In this case, we already have a signal and we want to generate noise to give us a desired SNR.

While noise can come in different flavors depending on what you are modeling, a good start (especially for this radio telescope example) is Additive White Gaussian Noise (AWGN). As stated in the previous answers, to model AWGN you need to add a zero-mean gaussian random variable to your original signal. The variance of that random variable will affect the average noise power.

For a Gaussian random variable X, the average power , also known as the second moment, is
[3]

So for white noise, and the average power is then equal to the variance .

When modeling this in python, you can either
1. Calculate variance based on a desired SNR and a set of existing measurements, which would work if you expect your measurements to have fairly consistent amplitude values.
2. Alternatively, you could set noise power to a known level to match something like receiver noise. Receiver noise could be measured by pointing the telescope into free space and calculating average power.

Either way, it's important to make sure that you add noise to your signal and take averages in the linear space and not in dB units.

Here's some code to generate a signal and plot voltage, power in Watts, and power in dB:

# Signal Generation
# matplotlib inline

import numpy as np
import matplotlib.pyplot as plt

t = np.linspace(1, 100, 1000)
x_volts = 10*np.sin(t/(2*np.pi))
plt.subplot(3,1,1)
plt.plot(t, x_volts)
plt.title('Signal')
plt.ylabel('Voltage (V)')
plt.xlabel('Time (s)')
plt.show()

x_watts = x_volts ** 2
plt.subplot(3,1,2)
plt.plot(t, x_watts)
plt.title('Signal Power')
plt.ylabel('Power (W)')
plt.xlabel('Time (s)')
plt.show()

x_db = 10 * np.log10(x_watts)
plt.subplot(3,1,3)
plt.plot(t, x_db)
plt.title('Signal Power in dB')
plt.ylabel('Power (dB)')
plt.xlabel('Time (s)')
plt.show()

Here's an example for adding AWGN based on a desired SNR:

# Adding noise using target SNR

# Set a target SNR
target_snr_db = 20
# Calculate signal power and convert to dB 
sig_avg_watts = np.mean(x_watts)
sig_avg_db = 10 * np.log10(sig_avg_watts)
# Calculate noise according to [2] then convert to watts
noise_avg_db = sig_avg_db - target_snr_db
noise_avg_watts = 10 ** (noise_avg_db / 10)
# Generate an sample of white noise
mean_noise = 0
noise_volts = np.random.normal(mean_noise, np.sqrt(noise_avg_watts), len(x_watts))
# Noise up the original signal
y_volts = x_volts + noise_volts

# Plot signal with noise
plt.subplot(2,1,1)
plt.plot(t, y_volts)
plt.title('Signal with noise')
plt.ylabel('Voltage (V)')
plt.xlabel('Time (s)')
plt.show()
# Plot in dB
y_watts = y_volts ** 2
y_db = 10 * np.log10(y_watts)
plt.subplot(2,1,2)
plt.plot(t, 10* np.log10(y_volts**2))
plt.title('Signal with noise (dB)')
plt.ylabel('Power (dB)')
plt.xlabel('Time (s)')
plt.show()

And here's an example for adding AWGN based on a known noise power:

# Adding noise using a target noise power

# Set a target channel noise power to something very noisy
target_noise_db = 10

# Convert to linear Watt units
target_noise_watts = 10 ** (target_noise_db / 10)

# Generate noise samples
mean_noise = 0
noise_volts = np.random.normal(mean_noise, np.sqrt(target_noise_watts), len(x_watts))

# Noise up the original signal (again) and plot
y_volts = x_volts + noise_volts

# Plot signal with noise
plt.subplot(2,1,1)
plt.plot(t, y_volts)
plt.title('Signal with noise')
plt.ylabel('Voltage (V)')
plt.xlabel('Time (s)')
plt.show()
# Plot in dB
y_watts = y_volts ** 2
y_db = 10 * np.log10(y_watts)
plt.subplot(2,1,2)
plt.plot(t, 10* np.log10(y_volts**2))
plt.title('Signal with noise')
plt.ylabel('Power (dB)')
plt.xlabel('Time (s)')
plt.show()

Something along these lines, using ABC

class Shape(object):
    __metaclass__ = abc.ABCMeta

    @abc.abstractmethod
    def method_to_implement(self, input):

 MarginLayoutParams layoutParams = (MarginLayoutParams) getLayoutParams();
 layoutParams.setMargins(leftMargin, topMargin, rightMargin, bottomMargin);

Use the native function htmlspecialchars. It will escape from all special character. If you want to escape from a quote specifically, use with ENT_COMPAT or ENT_QUOTES. Here is the example:

$str = "Jane & 'Tarzan'";
echo htmlspecialchars($str, ENT_COMPAT); // Will only convert double quotes
echo "<br>";

echo htmlspecialchars($str, ENT_QUOTES); // Converts double and single quotes
echo "<br>";

echo htmlspecialchars($str, ENT_NOQUOTES); // Does not convert any quotes

The output would be like this:

Jane &amp; 'Tarzan'<br>
Jane &amp; &#039;Tarzan&#039;<br>
Jane &amp; 'Tarzan'

Console cons = System.console();

The above code line creates cons as a null reference. The code and output are given below:

Console cons = System.console();
if (cons != null) {
    System.out.println("Enter single character: ");
    char c = (char) cons.reader().read();
    System.out.println(c);
}else{
    System.out.println(cons);
}

Output :

null

The code was tested on macbook pro with java version "1.6.0_37"

Finally i found a way to clone specific commit using git cherry-pick. Assuming you don't have any repository in local and you are pulling specific commit from remote,

1) create empty repository in local and git init

2) git remote add origin "url-of-repository"

3) git fetch origin [this will not move your files to your local workspace unless you merge]

4) git cherry-pick "Enter-long-commit-hash-that-you-need"

Done.This way, you will only have the files from that specific commit in your local.

Enter-long-commit-hash:

You can get this using -> git log --pretty=oneline

You can use somthing like this.

render () {
    var btnClass = 'btn';
    if (this.state.isPressed) btnClass += ' btn-pressed';
    else if (this.state.isHovered) btnClass += ' btn-over';
    return <button className={btnClass}>{this.props.label}</button>;
  }

Or else, you can use classnames NPM package to make dynamic and conditional className props simpler to work with (especially more so than conditional string manipulation).

classNames('foo', 'bar'); // => 'foo bar'
classNames('foo', { bar: true }); // => 'foo bar'
classNames({ 'foo-bar': true }); // => 'foo-bar'
classNames({ 'foo-bar': false }); // => ''
classNames({ foo: true }, { bar: true }); // => 'foo bar'
classNames({ foo: true, bar: true }); // => 'foo bar'

If you use jquery.ui, try this code:

$.position.scrollbarWidth()

You forgot to put z as an bind variable.

The following EXECUTE command runs a PL/SQL statement that references a stored procedure:

SQL> EXECUTE -
> :Z := EMP_SALE.HIRE('JACK','MANAGER','JONES',2990,'SALES')

Note that the value returned by the stored procedure is being return into :Z

You can give this simple jQuery plugin (AnimateScroll) a whirl. It is quite easy to use.

1. Scroll to the top of the page:

$('body').animatescroll();

2. Scroll to an element with ID section-1:

$('#section-1').animatescroll({easing:'easeInOutBack'});

I viewed the Eclipse ADT documentation and found out the way to get around this issue. I was able to Update My SDK Tool to 22.0.4 (Latest Version).

Solution is: First Update ADT to 22.0.4 and then Update SDK Tool to 22.0.4

The above link says,

ADT 22.0.4 is designed for use with SDK Tools r22.0.4. If you haven't already installed SDK Tools r22.0.4 into your SDK, use the Android SDK Manager to do so

What I had to do was update my ADT to 22.0.4 (Latest Version) and then I was able to update SDK tool to 22.0.4. I thought only SDK Tool has been updated not ADT, so I was updating the SDK Tool with Older ADT Version (22.0.1).

How to Update your ADT to Latest Version

1. In Eclipse go to Help

2. Install New Software ---> Add

3. inside Add Repository write the Name: ADT (or whatever you want)

4. Location: https://dl-ssl.google.com/android/eclipse/

5. after loading you should get Developer Tools and NDK Plugins

6. check both if you want to use the Native Developer Kit (NDK) in the future or check

7. Developer Tool only

8. click Next

9. Finish

Its not really possible to perform a 'mouse hover' action, instead you need to chain all of the actions that you want to achieve in one go. So move to the element that reveals the others, then during the same chain, move to the now revealed element and click on it.

When using Action Chains you have to remember to 'do it like a user would'.

Actions action = new Actions(webdriver);
WebElement we = webdriver.findElement(By.xpath("html/body/div[13]/ul/li[4]/a"));
action.moveToElement(we).moveToElement(webdriver.findElement(By.xpath("/expression-here"))).click().build().perform();

Whenever you are creating objects of class you have to check the whether the object is null or not using the below code.

Example: object1 is object of class

void myFunction(object1)
{
  if(object1!=null)
  {
     object1.value1 //If we miss the null check then here we get the Null Reference exception
  }
}

In Rails 3 and newer:

Rails.root

which returns a Pathname object. If you want a string you have to add .to_s. If you want another path in your Rails app, you can use join like this:

Rails.root.join('app', 'assets', 'images', 'logo.png')

In Rails 2 you can use the RAILS_ROOT constant, which is a string.

 Date.prototype.AddDays = function (days) {
    days = parseInt(days, 10);
    return new Date(this.valueOf() + 1000 * 60 * 60 * 24 * days);
}

Example

var dt = new Date();
console.log(dt.AddDays(-30));
console.log(dt.AddDays(-10));
console.log(dt.AddDays(-1));
console.log(dt.AddDays(0));
console.log(dt.AddDays(1));
console.log(dt.AddDays(10));
console.log(dt.AddDays(30));

byte test[] = new byte[3];
test[0] = 0x0A;
test[1] = 0xFF;
test[2] = 0x01;

for (byte theByte : test)
{
  System.out.println(Integer.toHexString(theByte));
}

NOTE: test[1] = 0xFF; this wont compile, you cant put 255 (FF) into a byte, java will want to use an int.

you might be able to do...

test[1] = (byte) 0xFF;

I'd test if I was near my IDE (if I was near my IDE I wouln't be on Stackoverflow)

To answer why you're getting a Monday and not a Sunday:

You're adding a number of weeks to the date 0. What is date 0? 1900-01-01. What was the day on 1900-01-01? Monday. So in your code you're saying, how many weeks have passed since Monday, January 1, 1900? Let's call that [n]. Ok, now add [n] weeks to Monday, January 1, 1900. You should not be surprised that this ends up being a Monday. DATEADD has no idea that you want to add weeks but only until you get to a Sunday, it's just adding 7 days, then adding 7 more days, ... just like DATEDIFF only recognizes boundaries that have been crossed. For example, these both return 1, even though some folks complain that there should be some sensible logic built in to round up or down:

SELECT DATEDIFF(YEAR, '2010-01-01', '2011-12-31');
SELECT DATEDIFF(YEAR, '2010-12-31', '2011-01-01');

To answer how to get a Sunday:

If you want a Sunday, then pick a base date that's not a Monday but rather a Sunday. For example:

DECLARE @dt DATE = '1905-01-01';
SELECT [start_of_week] = DATEADD(WEEK, DATEDIFF(WEEK, @dt, CURRENT_TIMESTAMP), @dt);

This will not break if you change your DATEFIRST setting (or your code is running for a user with a different setting) - provided that you still want a Sunday regardless of the current setting. If you want those two answers to jive, then you should use a function that does depend on the DATEFIRST setting, e.g.

SELECT DATEADD(DAY, 1-DATEPART(WEEKDAY, CURRENT_TIMESTAMP), CURRENT_TIMESTAMP);

So if you change your DATEFIRST setting to Monday, Tuesday, what have you, the behavior will change. Depending on which behavior you want, you could use one of these functions:

CREATE FUNCTION dbo.StartOfWeek1 -- always a Sunday
(
    @d DATE
)
RETURNS DATE
AS
BEGIN
    RETURN (SELECT DATEADD(WEEK, DATEDIFF(WEEK, '19050101', @d), '19050101'));
END
GO

...or...

CREATE FUNCTION dbo.StartOfWeek2 -- always the DATEFIRST weekday
(
    @d DATE
)
RETURNS DATE
AS
BEGIN
    RETURN (SELECT DATEADD(DAY, 1-DATEPART(WEEKDAY, @d), @d));
END
GO

Now, you have plenty of alternatives, but which one performs best? I'd be surprised if there would be any major differences but I collected all the answers provided so far and ran them through two sets of tests - one cheap and one expensive. I measured client statistics because I don't see I/O or memory playing a part in the performance here (though those may come into play depending on how the function is used). In my tests the results are:

"Cheap" assignment query:

Function - client processing time / wait time on server replies / total exec time
Gandarez     - 330/2029/2359 - 0:23.6
me datefirst - 329/2123/2452 - 0:24.5
me Sunday    - 357/2158/2515 - 0:25.2
trailmax     - 364/2160/2524 - 0:25.2
Curt         - 424/2202/2626 - 0:26.3

"Expensive" assignment query:

Function - client processing time / wait time on server replies / total exec time
Curt         - 1003/134158/135054 - 2:15
Gandarez     -  957/142919/143876 - 2:24
me Sunday    -  932/166817/165885 - 2:47
me datefirst -  939/171698/172637 - 2:53
trailmax     -  958/173174/174132 - 2:54

I can relay the details of my tests if desired - stopping here as this is already getting quite long-winded. I was a bit surprised to see Curt's come out as the fastest at the high end, given the number of calculations and inline code. Maybe I'll run some more thorough tests and blog about it... if you guys don't have any objections to me publishing your functions elsewhere.

>>> a = numpy.full((2,4), True, dtype=bool)
>>> a[1][3]
True
>>> a
array([[ True,  True,  True,  True],
       [ True,  True,  True,  True]], dtype=bool)

numpy.full(Size, Scalar Value, Type). There is other arguments as well that can be passed, for documentation on that, check https://docs.scipy.org/doc/numpy/reference/generated/numpy.full.html

If you don't want to use the KnockoutValidation library you can write your own. Here's an example for a Mandatory field.

Add a javascript class with all you KO extensions or extenders, and add the following:

ko.extenders.required = function (target, overrideMessage) {
    //add some sub-observables to our observable
    target.hasError = ko.observable();
    target.validationMessage = ko.observable();

    //define a function to do validation
    function validate(newValue) {
    target.hasError(newValue ? false : true);
    target.validationMessage(newValue ? "" : overrideMessage || "This field is required");
    }

    //initial validation
    validate(target());

    //validate whenever the value changes
    target.subscribe(validate);

    //return the original observable
    return target;
};

Then in your viewModel extend you observable by:

self.dateOfPayment: ko.observable().extend({ required: "" }),

There are a number of examples online for this style of validation.

I think floats may work best for you here, if you dont want the element to occupy the whole line, float it left should work.

.feature_wrapper span {
    float: left;
    clear: left;
    display:inline
}

EDIT: now browsers have better support you can make use of the do inline-block.

.feature_wrapper span {
    display:inline-block;
    *display:inline; *zoom:1;
}

Depending on the text-align this will appear as through its inline while also acting like a block element.

In pandas you can do str.len with your boundary and using the Boolean result to filter it .

df[df['column name'].str.len().lt(2)]

The for loop runs immediately to completion while all your asynchronous operations are started. When they complete some time in the future and call their callbacks, the value of your loop index variable i will be at its last value for all the callbacks.

This is because the for loop does not wait for an asynchronous operation to complete before continuing on to the next iteration of the loop and because the async callbacks are called some time in the future. Thus, the loop completes its iterations and THEN the callbacks get called when those async operations finish. As such, the loop index is "done" and sitting at its final value for all the callbacks.

To work around this, you have to uniquely save the loop index separately for each callback. In Javascript, the way to do that is to capture it in a function closure. That can either be done be creating an inline function closure specifically for this purpose (first example shown below) or you can create an external function that you pass the index to and let it maintain the index uniquely for you (second example shown below).

As of 2016, if you have a fully up-to-spec ES6 implementation of Javascript, you can also use let to define the for loop variable and it will be uniquely defined for each iteration of the for loop (third implementation below). But, note this is a late implementation feature in ES6 implementations so you have to make sure your execution environment supports that option.

Use .forEach() to iterate since it creates its own function closure

someArray.forEach(function(item, i) {
    asynchronousProcess(function(item) {
        console.log(i);
    });
});

Create Your Own Function Closure Using an IIFE

var j = 10;
for (var i = 0; i < j; i++) {
    (function(cntr) {
        // here the value of i was passed into as the argument cntr
        // and will be captured in this function closure so each
        // iteration of the loop can have it's own value
        asynchronousProcess(function() {
            console.log(cntr);
        });
    })(i);
}

Create or Modify External Function and Pass it the Variable

If you can modify the asynchronousProcess() function, then you could just pass the value in there and have the asynchronousProcess() function the cntr back to the callback like this:

var j = 10;
for (var i = 0; i < j; i++) {
    asynchronousProcess(i, function(cntr) {
        console.log(cntr);
    });
}

Use ES6 let

If you have a Javascript execution environment that fully supports ES6, you can use let in your for loop like this:

const j = 10;
for (let i = 0; i < j; i++) {
    asynchronousProcess(function() {
        console.log(i);
    });
}

let declared in a for loop declaration like this will create a unique value of i for each invocation of the loop (which is what you want).

Serializing with promises and async/await

If your async function returns a promise, and you want to serialize your async operations to run one after another instead of in parallel and you're running in a modern environment that supports async and await, then you have more options.

async function someFunction() {
    const j = 10;
    for (let i = 0; i < j; i++) {
        // wait for the promise to resolve before advancing the for loop
        await asynchronousProcess();
        console.log(i);
    }
}

This will make sure that only one call to asynchronousProcess() is in flight at a time and the for loop won't even advance until each one is done. This is different than the previous schemes that all ran your asynchronous operations in parallel so it depends entirely upon which design you want. Note: await works with a promise so your function has to return a promise that is resolved/rejected when the asynchronous operation is complete. Also, note that in order to use await, the containing function must be declared async.

Run asynchronous operations in parallel and use Promise.all() to collect results in order

 function someFunction() {
     let promises = [];
     for (let i = 0; i < 10; i++) {
          promises.push(asynchonousProcessThatReturnsPromise());
     }
     return Promise.all(promises);
 }

 someFunction().then(results => {
     // array of results in order here
     console.log(results);
 }).catch(err => {
     console.log(err);
 });
