I've finally done it in this way.
Added a ServletContextListener that does the following:
public void contextInitialized(ServletContextEvent event) {
ServletContext context = event.getServletContext();
System.setProperty("rootPath", context.getRealPath("/"));
}
Then in the log4j.properties file:
log4j.appender.file.File=${rootPath}WEB-INF/logs/MyLog.log
By doing it in this way Log4j will write into the right folder as long as you don't use it before the "rootPath" system property has been set. This means that you cannot use it from the ServletContextListener itself but you should be able to use it from anywhere else in the app.
It should work on every web container and OS as it's not dependent on a container specific system property and it's not affected by OS specific path issues. Tested with Tomcat and Orion web containers and on Windows and Linux and it works fine so far.
What do you think?
This following program can handle large numbers ( number of digits greater than 20 )
package com.isEven.java;
import java.util.Scanner;
public class isEvenValuate{
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
String digit = in.next();
int y = Character.getNumericValue(digit.charAt(digit.length()-1));
boolean isEven = (y&1)==0;
if(isEven)
System.out.println("Even");
else
System.out.println("Odd");
}
}
Here is the output ::
122873215981652362153862153872138721637272

This because the input that the user inserts into the JOptionPane
is a String
and it is stored and returned as a String
.
Java cannot convert between strings and number by itself, you have to use specific functions, just use:
int ans = Integer.parseInt(JOptionPane.showInputDialog(...))
Apple have changed the name of the certificate that is issued. You can now use the same certificate for both development and production. While you can still request a development only certificate you can no longer request a production only certificate.
I'm afraid Aularon didn't provide enough steps to complete the process. With a little trial and error, I was able to successfully enable Gzipping on my dedicated WHM server.
Below are the steps:
Run EasyApache within WHM, select Deflate within the Exhaustive Options list, and rebuild the server.
Once done, goto Services Configuration >> Apache Configuration >> Include Editor >> Post VirtualHost Include, select All Versions, and then paste the mod_headers.c and mod_headers.c code (listed above in Aularon's post) on top of on another within the input field.

(This answer is from years ago, when it was the best answer. There is now a better answer below this. I haven't kept up with node.js, and I cannot delete this answer because it is marked "correct on this question". If you are thinking of down clicking, what do you want me to do?)
The key is to use the data
and end
events of a Readable Stream. Listen to these events:
stream.on('data', (chunk) => { ... });
stream.on('end', () => { ... });
When you receive the data
event, add the new chunk of data to a Buffer created to collect the data.
When you receive the end
event, convert the completed Buffer into a string, if necessary. Then do what you need to do with it.
You have correctly used "CURLOPT_COOKIEJAR" (writing) but you also need to set "CURLOPT_COOKIEFILE" (reading)
curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE);
curl_setopt ($ch, CURLOPT_COOKIEFILE, COOKIE_FILE);
Here is a small example you can run to test it:
[1,2,3,4,5,6,7,8,9].forEach(function(n){
var sum = 0;
console.log('Start for:' + n);
for (var i = 0; i < ( 10 - n) * 100000000; i++)
sum++;
console.log('Ended for:' + n, sum);
});
It will produce something like this(if it takes too less/much time, increase/decrease the number of iterations):
(index):48 Start for:1
(index):52 Ended for:1 900000000
(index):48 Start for:2
(index):52 Ended for:2 800000000
(index):48 Start for:3
(index):52 Ended for:3 700000000
(index):48 Start for:4
(index):52 Ended for:4 600000000
(index):48 Start for:5
(index):52 Ended for:5 500000000
(index):48 Start for:6
(index):52 Ended for:6 400000000
(index):48 Start for:7
(index):52 Ended for:7 300000000
(index):48 Start for:8
(index):52 Ended for:8 200000000
(index):48 Start for:9
(index):52 Ended for:9 100000000

You can load jpeg binary data as a file and parse the jpeg headers yourself. The one you are looking for is the 0xFFC0 or Start of Frame header:
Start of frame marker (FFC0)
* the first two bytes, the length, after the marker indicate the number of bytes, including the two length bytes, that this header contains
* P -- one byte: sample precision in bits (usually 8, for baseline JPEG)
* Y -- two bytes
* X -- two bytes
* Nf -- one byte: the number of components in the image
o 3 for color baseline JPEG images
o 1 for grayscale baseline JPEG images
* Nf times:
o Component ID -- one byte
o H and V sampling factors -- one byte: H is first four bits and V is second four bits
o Quantization table number-- one byte
The H and V sampling factors dictate the final size of the component they are associated with. For instance, the color space defaults to YCbCr and the H and V sampling factors for each component, Y, Cb, and Cr, default to 2, 1, and 1, respectively (2 for both H and V of the Y component, etc.) in the Jpeg-6a library by the Independent Jpeg Group. While this does mean that the Y component will be twice the size of the other two components--giving it a higher resolution, the lower resolution components are quartered in size during compression in order to achieve this difference. Thus, the Cb and Cr components must be quadrupled in size during decompression.
For more info about the headers check out wikipedia's jpeg entry or I got the above info here.
I used a method similar to the code below which I got from this post at the sun forums:
import java.awt.Dimension;
import java.io.*;
public class JPEGDim {
public static Dimension getJPEGDimension(File f) throws IOException {
FileInputStream fis = new FileInputStream(f);
// check for SOI marker
if (fis.read() != 255 || fis.read() != 216)
throw new RuntimeException("SOI (Start Of Image) marker 0xff 0xd8 missing");
Dimension d = null;
while (fis.read() == 255) {
int marker = fis.read();
int len = fis.read() << 8 | fis.read();
if (marker == 192) {
fis.skip(1);
int height = fis.read() << 8 | fis.read();
int width = fis.read() << 8 | fis.read();
d = new Dimension(width, height);
break;
}
fis.skip(len - 2);
}
fis.close();
return d;
}
public static void main(String[] args) throws IOException {
System.out.println(getJPEGDimension(new File(args[0])));
}
}
Just use getContentResolver().openInputStream(uri)
to get an InputStream
from a URI.
Yes, quite straight forward:
Private _name As String
Public Property Name() As String
Get
Return _name
End Get
Private Set(ByVal value As String)
_name = value
End Set
End Property

Because you have to have an index on a foreign key field you can just create a simple index on the field 'AID'
CREATE INDEX aid_index ON mytable (AID);
and only then drop the unique index 'AID'
ALTER TABLE mytable DROP INDEX AID;
Unfortunately, all answers so far do not take into account that "a"
must not be considered equal to "A"
when it comes to sorting.
String[] array = {"b", "A", "C", "B", "a"};
// Approach 1
Arrays.sort(array);
// array is [A, B, C, a, b]
// Approach 2
Arrays.sort(array, String.CASE_INSENSITIVE_ORDER);
// array is [A, a, b, B, C]
// Approach 3
Arrays.sort(array, java.text.Collator.getInstance());
// array is [a, A, b, B, C]
In approach 1 any lower case letters are considered greater than any upper case letters.
Approach 2 makes it worse, since CASE_INSENSITIVE_ORDER considers "a"
and "A"
equal (comparation result is 0
). This makes sorting non-deterministic.
Approach 3 (using a java.text.Collator) is IMHO the only way of doing it correctly, since it considers "a"
and "A"
not equal, but puts them in the correct order according to the current (or any other desired) Locale.

a.mean()
takes an axis
argument:
In [1]: import numpy as np
In [2]: a = np.array([[40, 10], [50, 11]])
In [3]: a.mean(axis=1) # to take the mean of each row
Out[3]: array([ 25. , 30.5])
In [4]: a.mean(axis=0) # to take the mean of each col
Out[4]: array([ 45. , 10.5])
Or, as a standalone function:
In [5]: np.mean(a, axis=1)
Out[5]: array([ 25. , 30.5])
The reason your slicing wasn't working is because this is the syntax for slicing:
In [6]: a[:,0].mean() # first column
Out[6]: 45.0
In [7]: a[:,1].mean() # second column
Out[7]: 10.5

To install runlike
pip install runlike
As it accept container id as an argument so to extract container id use following command

runlike <docker container ID>
Charming Prince:
Only internet explorer allows the 4 byte hex color in the format of ARGB, where A is the Alpha channel. It can be used in gradient filters for example:
filter : ~"progid:DXImageTransform.Microsoft.Gradient(GradientType=@{dir},startColorstr=@{color1},endColorstr=@{color2})";
Where dir can be: 1(horizontal) or 0(vertical) And the color strings can be hex colors(#FFAAD3) or argb hex colors(#88FFAAD3).
Data type Range Storage
bigint -2^63 (-9,223,372,036,854,775,808) to 2^63-1 (9,223,372,036,854,775,807) 8 Bytes
int -2^31 (-2,147,483,648) to 2^31-1 (2,147,483,647) 4 Bytes
smallint -2^15 (-32,768) to 2^15-1 (32,767) 2 Bytes
tinyint 0 to 255 1 Byte
Example
The following example creates a table using the bigint, int, smallint, and tinyint data types. Values are inserted into each column and returned in the SELECT statement.
CREATE TABLE dbo.MyTable
(
MyBigIntColumn bigint
,MyIntColumn int
,MySmallIntColumn smallint
,MyTinyIntColumn tinyint
);
GO
INSERT INTO dbo.MyTable VALUES (9223372036854775807, 214483647,32767,255);
GO
SELECT MyBigIntColumn, MyIntColumn, MySmallIntColumn, MyTinyIntColumn
FROM dbo.MyTable;
Use the join
method from the Array type.
a.value = [a, b, c, d, e, f];
var stringValueYouWant = a.join();
The join
method will return a string that is the concatenation of all the array elements. It will use the first parameter you pass as a separator - if you don't use one, it will use the default separator, which is the comma.
You should start by profiling the SQL commands actually issued by the Entity Framework. Depending on your configuration (POCO, Self-Tracking entities) there is a lot room for optimizations. You can debug the SQL commands (which shouldn't differ between debug and release mode) using the ObjectSet<T>.ToTraceString()
method. If you encounter a query that requires further optimization you can use some projections to give EF more information about what you trying to accomplish.
Example:
Product product = db.Products.SingleOrDefault(p => p.Id == 10);
// executes SELECT * FROM Products WHERE Id = 10
ProductDto dto = new ProductDto();
foreach (Category category in product.Categories)
// executes SELECT * FROM Categories WHERE ProductId = 10
{
dto.Categories.Add(new CategoryDto { Name = category.Name });
}
Could be replaced with:
var query = from p in db.Products
where p.Id == 10
select new
{
p.Name,
Categories = from c in p.Categories select c.Name
};
ProductDto dto = new ProductDto();
foreach (var categoryName in query.Single().Categories)
// Executes SELECT p.Id, c.Name FROM Products as p, Categories as c WHERE p.Id = 10 AND p.Id = c.ProductId
{
dto.Categories.Add(new CategoryDto { Name = categoryName });
}
I just typed that out of my head, so this isn't exactly how it would be executed, but EF actually does some nice optimizations if you tell it everything you know about the query (in this case, that we will need the category-names). But this isn't like eager-loading (db.Products.Include("Categories")) because projections can further reduce the amount of data to load.
you dont have to do that in the Google chrome. Use the Internet explorer it offers the option to copy the css associated and after you copy and paste select the style and put that into another file .css to call into that html which you have created. Hope this will solve you problem than anything else:)
It is a bad idea to select * from anything, period. This is why SSMS adds every field name, even if there are hundreds, instead of select *. It is extremely inefficient regardless of how large the table is. If you don't know what the fields are, its still more efficient to pull them out of the INFORMATION_SCHEMA database than it is to select *.
A better query would be:
SELECT
COLUMN_NAME,
Case
When DATA_TYPE In ('varchar', 'char', 'nchar', 'nvarchar', 'binary')
Then convert(varchar(MAX), CHARACTER_MAXIMUM_LENGTH)
When DATA_TYPE In ('numeric', 'int', 'smallint', 'bigint', 'tinyint')
Then convert(varchar(MAX), NUMERIC_PRECISION)
When DATA_TYPE = 'bit'
Then convert(varchar(MAX), 1)
When DATA_TYPE IN ('decimal', 'float')
Then convert(varchar(MAX), Concat(Concat(NUMERIC_PRECISION, ', '), NUMERIC_SCALE))
When DATA_TYPE IN ('date', 'datetime', 'smalldatetime', 'time', 'timestamp')
Then ''
End As DATALEN,

I noticed that you can also get errors if you don't specify the angles correctly, even when using glm::rotate(Model, angle_in_degrees, glm::vec3(x, y, z))
you still might run into problems. The fix I found for this was specifying the type as glm::rotate(Model, (glm::mediump_float)90, glm::vec3(x, y, z))
instead of just saying glm::rotate(Model, 90, glm::vec3(x, y, z))
Or just write the second argument, the angle in radians (previously in degrees), as a float with no cast needed such as in:
glm::mat4 rotationMatrix = glm::rotate(glm::mat4(1.0f), 3.14f, glm::vec3(1.0));
You can add glm::radians() if you want to keep using degrees. And add the includes:
#include "glm/glm.hpp"
#include "glm/gtc/matrix_transform.hpp"
You can use BackgroundScheduler()
from APScheduler package (v3.5.3):
import time
import atexit
from apscheduler.schedulers.background import BackgroundScheduler
def print_date_time():
print(time.strftime("%A, %d. %B %Y %I:%M:%S %p"))
scheduler = BackgroundScheduler()
scheduler.add_job(func=print_date_time, trigger="interval", seconds=3)
scheduler.start()
# Shut down the scheduler when exiting the app
atexit.register(lambda: scheduler.shutdown())
Note that two of these schedulers will be launched when Flask is in debug mode. For more information, check out this question.
In an XML file, there is a sequence of declarations, and you may override a previous definition with a newer one. When you use annotations, there is no notion of before or after. All the beans are at the same level. You defined two beans with the same name, and Spring doesn't know which one it should choose.
Give them a different name (staticConverterDAO, inMemoryConverterDAO for example), create an alias in the Spring XML file (theConverterDAO for example), and use this alias when injecting the converter:
@Autowired @Qualifier("theConverterDAO")
This seems homework-y, so I'll give a hint rather than a detailed explanation. Correct me if I've assumed wrong.
You're doing fine as far as bailing out when you see an even divisor.
But you're printing 'count' as soon as you see even one number that doesn't divide into it. 2, for instance, does not divide evenly into 9. But that doesn't make 9 a prime. You might want to keep going until you're sure no number in the range matches.
(as others have replied, a Sieve is a much more efficient way to go... just trying to help you understand why this specific code isn't doing what you want)
Access contentResolver in Kotlin , inside activities, Object classes &... :

This answer has a problem:
style="text-transform: uppercase"
it also converts the place holder word to upper case which is inconvenient
placeholder="first name"
when rendering the input, it writes "first name" placeholder as uppercase
FIRST NAME
so i wrote something better:
onkeypress="this.value = this.value + event.key.toUpperCase(); return false;"
it works good!, but it has some side effects if your javascript code is complex,
hope it helps somebody to give him/her an idea to develop a better solution.
Encrypting using openssl_encrypt() The openssl_encrypt function provides a secured and easy way to encrypt your data.
In the script below, we use the AES128 encryption method, but you may consider other kind of encryption method depending on what you want to encrypt.
<?php
$message_to_encrypt = "Yoroshikune";
$secret_key = "my-secret-key";
$method = "aes128";
$iv_length = openssl_cipher_iv_length($method);
$iv = openssl_random_pseudo_bytes($iv_length);
$encrypted_message = openssl_encrypt($message_to_encrypt, $method, $secret_key, 0, $iv);
echo $encrypted_message;
?>
Here is an explanation of the variables used :
message_to_encrypt : the data you want to encrypt secret_key : it is your ‘password’ for encryption. Be sure not to choose something too easy and be careful not to share your secret key with other people method : the method of encryption. Here we chose AES128. iv_length and iv : prepare the encryption using bytes encrypted_message : the variable including your encrypted message
Decrypting using openssl_decrypt() Now you encrypted your data, you may need to decrypt it in order to re-use the message you first included into a variable. In order to do so, we will use the function openssl_decrypt().
<?php
$message_to_encrypt = "Yoroshikune";
$secret_key = "my-secret-key";
$method = "aes128";
$iv_length = openssl_cipher_iv_length($method);
$iv = openssl_random_pseudo_bytes($iv_lenght);
$encrypted_message = openssl_encrypt($message_to_encrypt, $method, $secret_key, 0, $iv);
$decrypted_message = openssl_decrypt($encrypted_message, $method, $secret_key, 0, $iv);
echo $decrypted_message;
?>
The decrypt method proposed by openssl_decrypt() is close to openssl_encrypt().
The only difference is that instead of adding $message_to_encrypt, you will need to add your already encrypted message as the first argument of openssl_decrypt().
That is all you have to do.
Suppose your element is entire [object HTMLDocument]
. You can convert it to a String this way:
const htmlTemplate = `<!DOCTYPE html><html lang="en"><head></head><body></body></html>`;
const domparser = new DOMParser();
const doc = domparser.parseFromString(htmlTemplate, "text/html"); // [object HTMLDocument]
const doctype = '<!DOCTYPE html>';
const html = doc.documentElement.outerHTML;
console.log(doctype + html);

You expose ports using the EXPOSE keyword in the Dockerfile or the --expose flag to docker run. Exposing ports is a way of documenting which ports are used, but does not actually map or open any ports. Exposing ports is optional.

If you want to be allowed to shutdown the memcached server you can give it that option before start it :
memcached -A &
With this option when you connect to memcached server for example:
telnet localhost 11211
then you can use shutdown
command to shutdown the server. You can also shutdown the memcached server when it is run as a process, first find the process PID using:
pidof memcached
then use:
kill PID command

There is no right way, but you can initialize an array of literals:
char **values = (char *[]){"a", "b", "c"};
or you can allocate each and initialize it:
char **values = malloc(sizeof(char*) * s);
for(...)
{
values[i] = malloc(sizeof(char) * l);
//or
values[i] = "hello";
}
I thought my issue was due to my machine.config per answers I found online but the culprit turned out to be in the project's web.config that was clearing out the DbProviderFactories.

<DbProviderFactories>

</DbProviderFactories>

A decorator takes the function definition and creates a new function that executes this function and transforms the result.
@deco
def do():
...
is equivalent to:
do = deco(do)
def deco(func):
def inner(letter):
return func(letter).upper() #upper
return inner
This
@deco
def do(number):
return chr(number) # number to letter
is equivalent to this
def do2(number):
return chr(number)
do2 = deco(do2)
65 <=> 'a'
print(do(65))
print(do2(65))
>>> B
>>> B
To understand the decorator, it is important to notice, that decorator created a new function do which is inner that executes function and transforms the result.
Yep, just use the trailing slash to recursively pull the directory. Works for me with Nexus 5 and current version of adb (March 2014).
A space may only be encoded to "+" in the "application/x-www-form-urlencoded" content-type key-value pairs query part of an URL. In my opinion, this is a MAY, not a MUST. In the rest of URLs, it is encoded as %20.
In my opinion, it's better to always encode spaces as %20, not as "+", even in the query part of an URL, because it is the HTML specification (RFC-1866) that specified that space characters should be encoded as "+" in "application/x-www-form-urlencoded" content-type key-value pairs (see paragraph 8.2.1. subparagraph 1.)
This way of encoding form data is also given in later HTML specifications. For example, look for relevant paragraphs about application/x-www-form-urlencoded in HTML 4.01 Specification, and so on.
Here is a sample string in URL where the HTML specification allows encoding spaces as pluses: "http://example.com/over/there?name=foo+bar". So, only after "?", spaces can be replaced by pluses. In other cases, spaces should be encoded to %20. But since it's hard to correctly determine the context, it's the best practice to never encode spaces as "+".
I would recommend to percent-encode all character except "unreserved" defined in RFC-3986, p.2.3
unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
The implementation depends on the programming language that you chose.
If your URL contains national characters, first encode them to UTF-8 and then percent-encode the result.
This is another way to do it. I think maybe a little more general:
df.ix[:,-1]
Basically http.antMatcher()
tells Spring to only configure HttpSecurity
if the path matches this pattern.
One that I use often:
Integer.parseInt("1234");
Point is, there are plenty of ways to do this, all equally valid. As to which is most optimum/efficient, you'd have to ask someone else.
You can use CurrentDirectory property.
Dim WshShell, strCurDir
Set WshShell = CreateObject("WScript.Shell")
strCurDir = WshShell.CurrentDirectory
WshShell.Run strCurDir & "\attribute.exe", 0
Set WshShell = Nothing
You can convert ZonedDateTime to an instant, which you can use directly with Date.
Date.from(java.time.ZonedDateTime.now().toInstant());

I know this is an old question. But I figure out an alternative way to use the library in Swift project, which might be helpful for those who don't want to import framework introduced in these answers.
In Swift project, create a Objective-C bridging header, create NSData category (or custom class that to use the library) in Objective-C. The only drawback would be that you have to write all implementation code in Objective-C. For example:
#import "NSData+NSDataEncryptionExtension.h"
#import <CommonCrypto/CommonCryptor.h>
@implementation NSData (NSDataEncryptionExtension)
- (NSData *)AES256EncryptWithKey:(NSString *)key {
//do something
}
- (NSData *)AES256DecryptWithKey:(NSString *)key {
//do something
}
And then in your objective-c bridging header, add this
#import "NSData+NSDataEncryptionExtension.h"
And then in Swift class do similar thing:
public extension String {
func encryp(withKey key:String) -> String? {
if let data = self.data(using: .utf8), let encrypedData = NSData(data: data).aes256Encrypt(withKey: key) {
return encrypedData.base64EncodedString()
}
return nil
}
func decryp(withKey key:String) -> String? {
if let data = NSData(base64Encoded: self, options: []), let decrypedData = data.aes256Decrypt(withKey: key) {
return decrypedData.UTF8String
}
return nil
}
}
It works as expected.
Read this Bug Issue: http://bugs.jquery.com/ticket/11586
Quoting the RFC 2616 Fielding
The
DELETE
method requests that the origin server delete the resource identified by the Request-URI.
So you need to pass the data in the URI
$.ajax({
url: urlCall + '?' + $.param({"Id": Id, "bolDeleteReq" : bolDeleteReq}),
type: 'DELETE',
success: callback || $.noop,
error: errorCallback || $.noop
});
If you're looking to paginate results, use the integrated paginator, it works great!
$games = Game::paginate(30);
// $games->results = the 30 you asked for
// $games->links() = the links to next, previous, etc pages
Also, if you need to format telephone number on output only, you can use a custom filter like this one:
angular.module('ng').filter('tel', function () {
return function (tel) {
if (!tel) { return ''; }
var value = tel.toString().trim().replace(/^\+/, '');
if (value.match(/[^0-9]/)) {
return tel;
}
var country, city, number;
switch (value.length) {
case 10: // +1PPP####### -> C (PPP) ###-####
country = 1;
city = value.slice(0, 3);
number = value.slice(3);
break;
case 11: // +CPPP####### -> CCC (PP) ###-####
country = value[0];
city = value.slice(1, 4);
number = value.slice(4);
break;
case 12: // +CCCPP####### -> CCC (PP) ###-####
country = value.slice(0, 3);
city = value.slice(3, 5);
number = value.slice(5);
break;
default:
return tel;
}
if (country == 1) {
country = "";
}
number = number.slice(0, 3) + '-' + number.slice(3);
return (country + " (" + city + ") " + number).trim();
};
});
Then you can use this filter in your template:
{{ phoneNumber | tel }}
<span ng-bind="phoneNumber | tel"></span>
To override the default entrypoint, use entrypoint
option. To pass the arguments use command
.
Here is the example of replacing bash
with sh
in ubuntu
image:
version: '3'
services:
sh:
entrypoint: /bin/sh
command: -c "ps $$(echo $$$$)"
image: ubuntu
tty: true
bash:
entrypoint: /bin/bash
command: -c "ps $$(echo $$$$)"
image: ubuntu
tty: true
Here is the output:
$ docker-compose up

I think Cycle Sort is a pretty neat sorting algorithm.
It's a sorting algorithm used to minimize the total number of writes. This is particularly useful when you're dealing with flash memory where the life-span of the flash memory is proportional to the amount of writes. Here is the Wikipedia article, but I recommend going to the first link. (nice visuals!)
You concrete problem is caused because you're mixing discouraged and old school scriptlets <% %>
with its successor EL ${}
. They do not share the same variable scope. The allFestivals
is not available in scriptlet scope and the i
is not available in EL scope.
You should install JSTL (<-- click the link for instructions) and declare it in top of JSP as follows:
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
and then iterate over the list as follows:
<c:forEach items="${allFestivals}" var="festival">
<tr>
<td>${festival.festivalName}</td>
<td>${festival.location}</td>
<td>${festival.startDate}</td>
<td>${festival.endDate}</td>
<td>${festival.URL}</td>
</tr>
</c:forEach>
(beware of possible XSS attack holes, use <c:out>
accordingly)
Don't forget to remove the <jsp:useBean>
as it has no utter value here when you're using a servlet as model-and-view controller. It would only lead to confusion. See also our servlets wiki page. Further you would do yourself a favour to disable scriptlets by the following entry in web.xml
so that you won't accidently use them:
<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<scripting-invalid>true</scripting-invalid>
</jsp-property-group>

Assuming this is a windows system and we are using gradle-2.1-all [Applicable to any gradle version, just change the version as we need]
All the gradles can be found in http://services.gradle.org/distributions/
Check the <Your Project>\gradle\wrapper\gradle-wrapper.properties
Make sure the distributionUrl is
distributionUrl=http\://services.gradle.org/distributions/gradle-2.1-all.zip
This is enough as it will automatically download the gradle.
After doing the above stuff, if you have downloaded the zip, paste the gradle-2.1-all.zip in
C:\Users\<username>\.gradle\wrapper\dists\gradle-2.1-all\<some_hash_key>\
It will save the extra downloading time.
request.raw_response
is now deprecated. Use request.body
instead to process non-conventional form data such as XML payloads, binary images, etc.
Thought I would throw in a variation to the use of the os.path.splitext without the need to use array indexing.
The function always returns a (root, ext)
pair so it is safe to use:
root, ext = os.path.splitext(path)
Example:
>>> import os
>>> path = 'my_text_file.txt'
>>> root, ext = os.path.splitext(path)
>>> root
'my_text_file'
>>> ext
'.txt'
You've made an array of arrays (multidimensional), so options[0] in this case is the size array. you need to reference the first element of the child, which for you is: options[0][0].
If you wanted to loop through all entries you can use the for .. in ...
syntax which is described here.
var a = [1,2,4,5,120,12];
for (var val in t) {
console.log(t[val]);
}
var b = ['S','M','L'];
var both = [a,b];
for (var val in both) {
for(val2 in both[val]){console.log(both[val][val2])}
}
The answer by @akrun certainly does the trick. For future googlers who want to understand why, here is an explanation...
The new variable needs to be created first.
The variable "valueBin" needs to be already in the df in order for the conditional assignment to work. Essentially, the syntax of the code is correct. Just add one line in front of the code chuck to create this name --
df$newVariableName <- NA
Then you continue with whatever conditional assignment rules you have, like
df$newVariableName[which(df$oldVariableName<=250)] <- "<=250"
I blame whoever wrote that package's error message... The debugging was made especially confusing by that error message. It is irrelevant information that you have two arrays in the df with different lengths. No. Simply create the new column first. For more details, consult this post https://www.r-bloggers.com/translating-weird-r-errors/
You can clean up a zombie process by killing its parent process with the following command:
kill -HUP $(ps -A -ostat,ppid | awk '{/[zZ]/{ print $2 }')
The first parentheses are for, if you will, order of operations. The 'result' of the set of parentheses surrounding the function definition is the function itself which, indeed, the second set of parentheses executes.
As to why it's useful, I'm not enough of a JavaScript wizard to have any idea. :P
Got the same error. Tried to start and stop dfs several times, cleared all directories that are mentioned in previous answers, but nothing helped.
The issue was resolved only after rebooting OS and configuring Hadoop from the scratch. (configuring Hadoop from the scratch without rebooting didn't work)
Disclaimer: I am involved in the rest2mobile open source project
Another alternative as a REST client is to use rest2mobile.
The approach is slightly different as it uses concrete rest examples to generate the client code for the REST service. The code replaces the REST URL and JSON payloads with native java methods and POJOs. It also automatically handles server connections, asynchronous invocations and POJO to/from JSON conversions.
Note that this tool comes in different flavors (cli, plugins, android/ios/js support) and you can use the android studio plugin to generate the API directly into your app.
All the code can be found on github here.
I just stumbled upon a combination of Mixin and Extend:
.block1 { box-shadow: 0 5px 10px #000; }
.block2 { box-shadow: 5px 0 10px #000; }
.block3 { box-shadow: 0 0 1px #000; }
@mixin customExtend($class){ @extend .#{$class}; }
like: @include customExtend(block1);
h1 {color: fff; @include customExtend(block2);}
Sass will compile only the mixins content to the extended blocks, which makes it able to combine blocks without generating duplicate code. The Extend logic only puts the classname of the Mixin import location in the block1, ..., ... {box-shadow: 0 5px 10px #000;}
If your arrays are character arrays(which seems to be the case), You need a strcat().
Your destination array should have enough space to accommodate the appended data though.
In C++, You are much better off using std::string and then you can use std::string::append()
A TextBlock does not actually inherit from Control so it does not have properties that you would generally associate with a Control. Your best bet for adding a border in a style is to replace the TextBlock with a Label

Maven is a software management tool that can boost your productivity. I believe that such a tool is essential for software development in a new era.
However, Maven isn't appropriate for all code bases. If you need to support a large legacy code page, or you import code from a third party, then it would be better to avoid using. Maven expects things to be in a certain way (convention over configuration). If you are starting a new project, then this is more than fine. If, however, you have a full system you need to support, the lack of flexibility is a nightmare.
Another reason that people usually complain about maven is the steep learning curve. Also IDE integration is still not very mature. Apache is offering two plug-ins for Eclipse. The one is "mature", the other one offers a new approach. I suppose the new wouldn't be needed if the first one was adequate.
Another, more serious complain about Maven, is the use of XML for doing programming job. Perhaps tools like Buildr are the way to go.

Using $resource
in AngularJS you can do:
task.service.js
$ngTask.factory("$taskService", [
"$resource",
function ($resource) {
var taskModelUrl = 'api/task/';
return {
rest: {
taskUpload: $resource(taskModelUrl, {
id: '@id'
}, {
save: {
method: "POST",
isArray: false,
headers: {"Content-Type": undefined},
transformRequest: angular.identity
}
})
}
};
}
]);
And then use it in a module:
task.module.js
$ngModelTask.controller("taskController", [
"$scope",
"$taskService",
function (
$scope,
$taskService,
) {
$scope.saveTask = function (name, file) {
var newTask,
payload = new FormData();
payload.append("name", name);
payload.append("file", file);
newTask = $taskService.rest.taskUpload.save(payload);
// check if exists
}
}

var date = new Date(someMillisecondValue);
var minute = date.getMinutes();
var hour = date.getHours();
var day = date.getDate();
var month = date.getMonth();
var year = date.getFullYear();
alert([minute, hour, day, month, year].join("\n"));
Multiple right answers were presented, but there are still more methods: Class.isAssignableFrom()
and simply attempting to cast the object (which might throw a ClassCastException
).
Let's summarize the possible ways to test if an object obj
is an instance of type C
:
// Method #1
if (obj instanceof C)
;
// Method #2
if (C.class.isInstance(obj))
;
// Method #3
if (C.class.isAssignableFrom(obj.getClass()))
;
// Method #4
try {
C c = (C) obj;
// No exception: obj is of type C or IT MIGHT BE NULL!
} catch (ClassCastException e) {
}
// Method #5
try {
C c = C.class.cast(obj);
// No exception: obj is of type C or IT MIGHT BE NULL!
} catch (ClassCastException e) {
}
null
handlingThere is a difference in null
handling though:
false
if obj
is null
(null
is not instance of anything).NullPointerException
obviously. null
because null
can be cast to any type!To remember:
null
is not an instance of any type but it can be cast to any type.
Class.getName()
should not be used to perform an "is-instance-of" test becase if the object is not of type C
but a subclass of it, it may have a completely different name and package (therefore class names will obviously not match) but it is still of type C
.Class.isAssignableFrom()
is not symmetric:obj.getClass().isAssignableFrom(C.class)
would return false
if the type of obj
is a subclass of C
.I had the same problem and came across this post. Nothing worked. After randomly playing around, I found that <embed ........ play="false">
stopped it from playing automatically. I now have the problem that I can't get a controller to appear, so can't start the movie! :S
Here's an alternate approach to the 'round up' part. Not the most brilliantly coded solution but it gets the job done, and this type of syntax is a bit easier to remember (plus would work for alignment values that aren't a power of 2). The uintptr_t
cast was necessary to appease the compiler; pointer arithmetic isn't very fond of division or multiplication.
void *mem = malloc(1024 + 15);
void *ptr = (void*) ((uintptr_t) mem + 15) / 16 * 16;
memset_16aligned(ptr, 0, 1024);
free(mem);
It can be very useful when flattening a hierarchy and/or mapping objects. Instead of:
if (Model.Model2 == null
|| Model.Model2.Model3 == null
|| Model.Model2.Model3.Model4 == null
|| Model.Model2.Model3.Model4.Name == null)
{
mapped.Name = "N/A"
}
else
{
mapped.Name = Model.Model2.Model3.Model4.Name;
}
It can be written like (same logic as above)
mapped.Name = Model.Model2?.Model3?.Model4?.Name ?? "N/A";
DotNetFiddle.Net Working Example.
(the ?? or null-coalescing operator is different than the ? or null conditional operator).
It can also be used out side of assignment operators with Action. Instead of
Action<TValue> myAction = null;
if (myAction != null)
{
myAction(TValue);
}
It can be simplified to:
myAction?.Invoke(TValue);
using System;
public class Program
{
public static void Main()
{
Action<string> consoleWrite = null;
consoleWrite?.Invoke("Test 1");
consoleWrite = (s) => Console.WriteLine(s);
consoleWrite?.Invoke("Test 2");
}
}
Result:
Test 2

Here is my code to resize an iframe with an external website. You need insert a code into the parent (with iframe code) page and in the external website as well, so, this won't work with you don't have access to edit the external website.
Local:
<IFRAME STYLE="width:100%;height:1px" SRC="http://www.remote-site.com/" FRAMEBORDER="no" BORDER="0" SCROLLING="no" ID="estframe"></IFRAME>
<SCRIPT>
var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
var eventer = window[eventMethod];
var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";
eventer(messageEvent,function(e) {
if (e.data.substring(0,3)=='frm') document.getElementById('estframe').style.height = e.data.substring(3) + 'px';
},false);
</SCRIPT>
You need this "frm" prefix to avoid problems with other embeded codes like Twitter or Facebook plugins. If you have a plain page, you can remove the "if" and the "frm" prefix on both pages (script and onload).
Remote:
You need jQuery to accomplish about "real" page height. I cannot realize how to do with pure JavaScript since you'll have problem when resize the height down (higher to lower height) using body.scrollHeight or related. For some reason, it will return always the biggest height (pre-redimensioned).
<BODY onload="parent.postMessage('frm'+$('#master').height(),'*')" STYLE="margin:0">
<SCRIPT SRC="path-to-jquery/jquery.min.js"></SCRIPT>
<DIV ID="master">
your content
</DIV>
So, parent page (iframe) has a 1px default height. The script inserts a "wait for message/event" from the iframe. When a message (post message) is received and the first 3 chars are "frm" (to avoid the mentioned problem), will get the number from 4th position and set the iframe height (style), including 'px' unit.
The external site (loaded in the iframe) will "send a message" to the parent (opener) with the "frm" and the height of the main div (in this case id "master"). The "*" in postmessage means "any source".
Hope this helps. Sorry for my english.
Uri.EscapeDataString
or HttpUtility.UrlEncode
is the correct way to escape a string meant to be part of a URL.
Take for example the string "Stack Overflow"
:
HttpUtility.UrlEncode("Stack Overflow")
--> "Stack+Overflow"
Uri.EscapeUriString("Stack Overflow")
--> "Stack%20Overflow"
Uri.EscapeDataString("Stack + Overflow")
--> Also encodes "+" to "%2b"
---->Stack%20%2B%20%20Overflow
Only the last is correct when used as an actual part of the URL (as opposed to the value of one of the query string parameters)
only
android:windowSoftInputMode="adjustResize"
in your activity tag inside Manifest file will do the trick
I had this problem. I somehow registered the device for generic team on apple. I don't remember how I did it now. Then I was able to overcome this error.
For MySql WorkBench, Please use below :
update emp as a
inner join department b on a.department_id=b.id
set a.department_name=b.name
where a.emp_id in (10,11,12);
Use this:
SimpleDateFormat format = new SimpleDateFormat("HH:mm");
Date d1 = format.parse(strStartTime);
Date d2 = format.parse(strEndTime);
long diff = d2.getTime() - d1.getTime();
long diffSeconds,diffMinutes,diffHours;
if (diff > 0) {
diffSeconds = diff / 1000 % 60;
diffMinutes = diff / (60 * 1000) % 60;
diffHours = diff / (60 * 60 * 1000);
}
else{
long diffpos = (24*((60 * 60 * 1000))) + diff;
diffSeconds = diffpos / 1000 % 60;
diffMinutes = diffpos / (60 * 1000) % 60;
diffHours = (diffpos / (60 * 60 * 1000));
}
(Also it is important that for example if the startTime it's 23:00 and endTime 1:00 to get a duration of 2:00.)
the "else" part can get it correct
Copy the files to the default directory for your other database files. To find out what that is, you can use the sp_helpfile procedure in SSMS. On my machine it is: C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQL\DATA
. By copying the files to this directory, they automatically get permissions applied that will allow the attach to succeed.
Here is a very good explanation :
This worked for me in ASP.NET Core MVC.
<script type="text/javascript">
var ar = @Html.Raw(Json.Serialize(Model.Addresses));
</script>
try this:
declare @i tinyint = 0,
@count tinyint,
@id int,
@name varchar(max)
select @count = count(*) from table
while (@i < @count)
begin
select @id = id, @name = name from table
order by nr asc offset @i rows fetch next 1 rows only
exec stored_proc @varName = @id, @otherVarName = 'test', @varForName = @name
set @i = @i + 1
end
I met the same problem. I found the answer in the website:http://www.17ext.com.
First,delete the JRE System Libraries. Then,import JRE System Libraries again.
I don't know why.However it fixed my problem,hope it can help you.
I did the test using java 8 It wont matter the order the builder always takes 0 milliseconds and the concat between 26 and 33 milliseconds under and iteration of a 1000 concatenation
Hope it helps try it with your ide
public void count() {
String result = "";
StringBuilder builder = new StringBuilder();
long millis1 = System.currentTimeMillis(),
millis2;
for (int i = 0; i < 1000; i++) {
builder.append("hello world this is the concat vs builder test enjoy");
}
millis2 = System.currentTimeMillis();
System.out.println("Diff: " + (millis2 - millis1));
millis1 = System.currentTimeMillis();
for (int i = 0; i < 1000; i++) {
result += "hello world this is the concat vs builder test enjoy";
}
millis2 = System.currentTimeMillis();
System.out.println("Diff: " + (millis2 - millis1));
}
r := strings(byteData)
This also works to turn []byte
into io.Reader
No method can be invoked on a object which is assigned a NULL
value. It will give a nullPointerException
. Hence, s2.length()
is giving an exception.
To populate the drop-down select box in laravel we have to follow the below steps.
From controller we have to get the value like this:
public function addCustomerLoyaltyCardDetails(){
$loyalityCardMaster = DB::table('loyality_cards')->pluck('loyality_card_id', 'loyalityCardNumber');
return view('admin.AddCustomerLoyaltyCardScreen')->with('loyalityCardMaster',$loyalityCardMaster);
}
And the same we can display in view:
<select class="form-control" id="loyalityCardNumber" name="loyalityCardNumber" >
@foreach ($loyalityCardMaster as $id => $name)
<option value="{{$name}}">{{$id}}</option>
@endforeach
</select>
This key value in drop down you can use as per your requirement. Hope it may help someone.
CTRL + H, then select regex (*) and write \n
Shorter version: CTRL+H ALT+R \n
Using .apply()
with a lambda
conversion function also works in this case:
total_rows['ColumnID'] = total_rows['ColumnID'].apply(lambda x: str(x))
For entire dataframes you can use .applymap()
.
(but in any case probably .astype()
is faster)
The problem is that the regex pattern is being HTML encoded twice, once when the regex is being built, and once when being rendered in your view.
For now, try wrapping your TextBoxFor in an Html.Raw
, like so:
@Html.Raw(Html.TextBoxFor(model => Model.FirstName, new { }))
It took me quite a while to figure out, how to not get a false
when using openssl_decrypt()
and get encrypt and decrypt working.
// cryptographic key of a binary string 16 bytes long (because AES-128 has a key size of 16 bytes)
$encryption_key = '58adf8c78efef9570c447295008e2e6e'; // example
$iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length('aes-256-cbc'));
$encrypted = openssl_encrypt($plaintext, 'aes-256-cbc', $encryption_key, OPENSSL_RAW_DATA, $iv);
$encrypted = $encrypted . ':' . base64_encode($iv);
// decrypt to get again $plaintext
$parts = explode(':', $encrypted);
$decrypted = openssl_decrypt($parts[0], 'aes-256-cbc', $encryption_key, OPENSSL_RAW_DATA, base64_decode($parts[1]));
If you want to pass the encrypted string via a URL, you need to urlencode the string:
$encrypted = urlencode($encrypted);
To better understand what is going on, read:
To generate 16 bytes long keys you can use:
$bytes = openssl_random_pseudo_bytes(16);
$hex = bin2hex($bytes);
To see error messages of openssl you can use: echo openssl_error_string();
Hope that helps.
Using --disable-web-security
switch is quite dangerous! Why disable security at all while you can just allow XMLHttpRequest to access files from other files using --allow-file-access-from-files
switch?
Before using these commands be sure to end all running instances of Chrome.
On Windows:

There's a facility to have a separate style sheet for print, using
<link type="text/css" rel="stylesheet" media="print" href="print.css">
I don't know if it does what you want though.
I had a similar issue when trying to access a service (old ASMX service). The call would work when accessing via an IP however when calling with an alias I would get the remote name could not be resolved.
Added the following to the config and it resolved the issue:

The screen of a mobile phone is made up of thousands of tiny dots known as pixels (px). A pixel is the smallest element which goes to make the picture. The more the number of pixels to make a picture or wording, the sharper it becomes and makes the smartphone screen more easily readable.
Screen resolution is measured in terms of number of pixels on the screen. Screen resolution is a commonly-used specification when buying a device, but it's actually not that useful when designing for Android because thinking of screens in terms of pixels ignores the notion of physical size, which for a touch device is really really important.
Density independent pixel (dp or dip) allow the designer to create assets that appear in a expected way, no matter the resolution or density of target device.
A density independent pixel (dp or dip) is equal to one pixel at the baseline density or 160 dpi (dots per inch).
1 px/1dp = 160 dpi/160 dpi
2 px/1dp = 320 dpi(2x)/160 dpi
where,
dpi is dots per inch
So, at 320 dpi, 1 dp is equal to 2 px.
Formula
px/dp = dpi/160dpi
Dots per inch (dpi) is a measure of the sharpness (that is, the density of illuminated points) on a display screen. The dots per inch for a given picture resolution will differ based on the overall screen size since the same number of pixels are being spread out over a different space.
Working with density independent pixels help us to deal with a situation like where you have two devices with same pixel resolution, but differing amount of space. Suppose in a case, a tablet and phone has the same pixel resolution 1280 by 800 pixels (160 dpi) and 800 by 1280 pixels (320 dpi) respectively.
Now because a tablet is at baseline density (160 dpi) its physical and density independent pixels sizes are the same, 1280 by 800. The phone on the other hand has a higher pixel density, so it has half as many density independent pixels as physical pixels. So a phone has 400 by 640 density independent pixels. So using a density-independent pixel makes it easier to mentally picture that tablet has much more space than the phone.
Similarly, if you have two devices with similar screen size, but different pixel density, say one is 800 by 1280 pixels (320 dpi), and the other is 400 by 640 pixels (160 dpi), we don't need to define totally different layouts for these two devices as we can measure assets in terms of density independent pixel which is same for both devices.
800 by 1280 pixels (320dpi)=400 by 640 density independent pixel (dp)
400 by 640 pixels (160 dpi)=400 by 640 density independent pixel (dp)
Scale independent pixels(sp) is the preferred unit for font size. For accessibility purposes, Android allows users to customize their device's font size. Users that have trouble reading text can increase their device's font size. You can normally find this option in the display setting on your phone or tablet under font size. It's often also available through the accessibility settings.
With scale independent pixels, 16 sp is exactly the same as 16 dp when the device's font size is normal or 100%. But when device's font size is large, for example 125%, 16 sp will translate to 20 dp or 1.25 times 16.
If you use dp as the unit for font size, then that piece of text has a specific physical size no matter if the user has customize device's font size. Using sp units will make a better experience for people with impaired eyesight.

Imagine you have have a Book model and a Page model,
1:N means:
One book can have **many** pages. One page can only be in **one** book.
N:N means:
One book can have **many** pages. And one page can be in **many** books.
Since you want to pivot multiple columns of data, I would first suggest unpivoting the result
, score
and grade
columns so you don't have multiple columns but you will have multiple rows.
Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:
select ratio, col, value
from GRAND_TOTALS
cross apply
(
select 'result', cast(result as varchar(10)) union all
select 'score', cast(score as varchar(10)) union all
select 'grade', grade
) c(col, value)
See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:
select ratio = col,
[current ratio], [gearing ratio], [performance ratio], total
from
(
select ratio, col, value
from GRAND_TOTALS
cross apply
(
select 'result', cast(result as varchar(10)) union all
select 'score', cast(score as varchar(10)) union all
select 'grade', grade
) c(col, value)
) d
pivot
(
max(value)
for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;
See SQL Fiddle with Demo. This will give you the result:
| RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO | TOTAL |
|--------|---------------|---------------|-------------------|-----------|
| grade | Good | Good | Satisfactory | Good |
| result | 1.29400 | 0.33840 | 0.04270 | (null) |
| score | 60.00000 | 70.00000 | 50.00000 | 180.00000 |

Git is supposed to understand what files already exist on the server, unless you somehow made a huge difference to your tree and the new changes need to be sent.
To create a new branch with a copy of your current state
git checkout -b new_branch #< create a new local branch with a copy of your code
git push origin new_branch #< pushes to the server
Can you please describe the steps you did to understand what might have made your repository need to send that much to the server.
Tomcat can tell you in several ways. Here's the easiest:
$ /path/to/catalina.sh version
Using CATALINA_BASE: /usr/local/apache-tomcat-7.0.29
Using CATALINA_HOME: /usr/local/apache-tomcat-7.0.29
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-7.0.29/temp
Using JRE_HOME: /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home
Using CLASSPATH: /usr/local/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.29/bin/tomcat-juli.jar
Server version: Apache Tomcat/7.0.29
Server built: Jul 3 2012 11:31:52
Server number: 7.0.29.0
OS Name: Mac OS X
OS Version: 10.7.4
Architecture: x86_64
JVM Version: 1.6.0_33-b03-424-11M3720
JVM Vendor: Apple Inc.
If you don't know where catalina.sh
is (or it never gets called), you can usually find it via ps
:
$ ps aux | grep catalina
chris 930 0.0 3.1 2987336 258328 s000 S Wed01PM 2:29.43 /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -Dnop -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.library.path=/usr/local/apache-tomcat-7.0.29/lib -Djava.endorsed.dirs=/usr/local/apache-tomcat-7.0.29/endorsed -classpath /usr/local/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.29/bin/tomcat-juli.jar -Dcatalina.base=/Users/chris/blah/blah -Dcatalina.home=/usr/local/apache-tomcat-7.0.29 -Djava.io.tmpdir=/Users/chris/blah/blah/temp org.apache.catalina.startup.Bootstrap start
From the ps
output, you can see both catalina.home
and catalina.base
. catalina.home
is where the Tomcat base files are installed, and catalina.base
is where the running configuration of Tomcat exists. These are often set to the same value unless you have configured your Tomcat for multiple (configuration) instances to be launched from a single Tomcat base install.
You can also interrogate the JVM directly if you can't find it in a ps
listing:
$ jinfo -sysprops 930 | grep catalina
Attaching to process ID 930, please wait...
Debugger attached successfully.
Server compiler detected.
JVM version is 20.8-b03-424
catalina.base = /Users/chris/blah/blah
[...]
catalina.home = /usr/local/apache-tomcat-7.0.29
If you can't manage that, you can always try to write a JSP that dumps the values of the two system properties catalina.home
and catalina.base
.
Try tracert to resolve the hostname. IE you have Ip address 8.8.8.8 so you would use; tracert 8.8.8.8
You can also restrict your action to just one class using the right pointed bracket (">"), as I have done in this code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style type="text/css">
span {
font-size:12px;
}
a {
color:green;
}
.test1>a:hover span {
display:none;
}
.test1>a:hover:before {
color:red;
content:"Apple";
}
</style>
</head>
<body>
<div class="test1">
<a href="#"><span>Google</span></a>
</div>
<div class="test2">
<a href="#"><span>Apple</span></a>
</div>
</body>
</html>
Note: The hover:before switch works only on the .test1 class
The code seems to be flawless!
Simple and plain.
So it should work on the phone. The emulator is having hard time playing videos, it happened to me too.
Try increasing the required API level to the latest, it might help!
Right click on opened project, chose Properties > Android > check the latest version on the right side...
Igor
std::string var = "sometext" + somevar + "sometext" + somevar;
This doesn't work because the additions are performed left-to-right and "sometext"
(the first one) is just a const char *
. It has no operator+
to call. The simplest fix is this:
std::string var = std::string("sometext") + somevar + "sometext" + somevar;
Now, the first parameter in the left-to-right list of +
operations is a std::string
, which has an operator+(const char *)
. That operator produces a string, which makes the rest of the chain work.
You can also make all the operations be on var
, which is a std::string
and so has all the necessary operators:
var = "sometext";
var += somevar;
var += "sometext";
var += somevar;

Simple version:
for /F "delims==, tokens=4" %a IN ('ping -n 2 127.0.0.1 ^| findstr /R "^Packets: Sent =.$"') DO (
if %a EQU 2 (
echo Success
) ELSE (
echo FAIL
)
)
But sometimes first ping just fail and second one work (or vice versa) right? So we want to get success when at least one ICMP reply has been returned successfully:
for /F "delims==, tokens=4" %a IN ('ping -n 2 192.168.1.1 ^| findstr /R "^Packets: Sent =.$"') DO (
if %a EQU 2 (
echo Success
) ELSE (
if %a EQU 1 (
echo Success
) ELSE (
echo FAIL
)
)
)
As all are given answers I want to add little more. I had also faced the same issue.
Why did your query fail? You have,
SELECT pid FROM planets WHERE userid = NULL;
This will not give you the expected result, because from mysql doc
In SQL, the NULL value is never true in comparison to any other value, even NULL. An expression that contains NULL always produces a NULL value unless otherwise indicated in the documentation for the operators and functions involved in the expression.
Emphasis mine.
To search for column values that are
NULL
, you cannot use anexpr = NULL
test. The following statement returns no rows, becauseexpr = NULL
is never true for any expression
SELECT pid FROM planets WHERE userid IS NULL;
To test for NULL
, use the IS NULL
and IS NOT NULL
operators.
NULL
.NULL
.I'm gathering from your question that userPick
is a String
value. You can compare it like this:
if (userPick.equalsIgnoreCase(computerPick.name())) . . .
As an aside, if you are guaranteed that computer
is always one of the values 1
, 2
, or 3
(and nothing else), you can convert it to a Gesture
enum with:
Gesture computerPick = Gesture.values()[computer - 1];

The way to do this using the Extention Methods, instead of the linq query syntax would be like this:
var results = workOrders.Join(plans,
wo => wo.WorkOrderNumber,
p => p.WorkOrderNumber,
(order,plan) => new {order.WorkOrderNumber, order.WorkDescription, plan.ScheduledDate}
);
To answer your original question, it's (x1, y1)
to (x2, y2)
.
For example,
This is to draw a horizontal line:
g.drawLine( 10, 30, 90, 30 );
vs
This is to draw a vertical line:

I hope it helps.
Note that a namespace in C++ really is just a name space. They don't provide any of the encapsulation that packages do in Java, so you probably won't use them as much.
I solve this the way Below
Animation anim = AnimationUtils.loadAnimation(this, R.anim.slide);
fg.startAnimation(anim);
this.fg.setVisibility(View.VISIBLE); //fg is a View object indicate fragment
Try this...
Give the element an ID, and also a class Name. Then you can nest the #IDName.className in your CSS.
Here's a better explanation https://css-tricks.com/multiple-class-id-selectors/
In my case the solution was to change NO to YES in the below function.
iOS 9+
- (BOOL)tableView:(UITableView *)tableView shouldHighlightRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
for i in count:
means for i in 7:
, which won't work. The bit after the in
should be of an iterable type, not a number. Try this:
for i in range(count):
first, get the container id of the desired container by
docker ps
you will get something like this:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3ac548b6b315 frontend_react-web "npm run start" 48 seconds ago Up 47 seconds 0.0.0.0:3000->3000/tcp frontend_react-web_1
now copy this container id and run the following command:
docker exec -it container_id sh
docker exec -it 3ac548b6b315 sh
It's worth mentioning that you can use the NODE_ENV
environment variable to achieve the same result. Particularly useful if you're containerizing your Node application (e.g. Docker).
NODE_ENV=production npm install
The above code will install all your dependencies but the dev ones (i.e. devDependencies
).
if you need to use environment variables in your Dockerfile
more information can be found here.
Environment variables are easy to overwrite whenever needed (e.g. if you want to run your test suite say on Travis CI). If that were the case you could do something like this:
docker run -v $(pwd):/usr/src/app --rm -it -e NODE_ENV=production node:8 npm install
production
- Default: false
Type: Boolean Set to true to run in "production" mode.
- devDependencies are not installed at the topmost level when running local npm install without any arguments.
- Set the NODE_ENV="production" for lifecycle scripts.
Happy containerization =)
Example:
.parent-class .flex-control-thumbs li {
width: auto;
float: none;
}
Demo:
.sample-class {
height: 50px;
width: 50px;
background: red;
}
.inner-page .sample-class {
background: green;
}

I tried the solutions above and none worked for me out of the box.
However http://www.baeldung.com/httpclient-post-http-request. Line 6 POST Multipart Request worked within seconds
public void whenSendMultipartRequestUsingHttpClient_thenCorrect()
throws ClientProtocolException, IOException {
CloseableHttpClient client = HttpClients.createDefault();
HttpPost httpPost = new HttpPost("http://www.example.com");
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.addTextBody("username", "John");
builder.addTextBody("password", "pass");
builder.addBinaryBody("file", new File("test.txt"),
ContentType.APPLICATION_OCTET_STREAM, "file.ext");
HttpEntity multipart = builder.build();
httpPost.setEntity(multipart);
CloseableHttpResponse response = client.execute(httpPost);
client.close();

In case Translate works locally but not remotly e.i group.Translate(typeof(NTAccount)
If you want to have the application code executes using the LOGGED IN USER identity, then enable impersonation. Impersonation can be enabled thru IIS or by adding the following element in the web.config.
<system.web>
<identity impersonate="true"/>
If impersonation is enabled, the application executes using the permissions found in your user account. So if the logged in user has access, to a specific network resource, only then will he be able to access that resource thru the application.
Thank PRAGIM tech for this information from his diligent video
Windows authentication in asp.net Part 87:
https://www.youtube.com/watch?v=zftmaZ3ySMc
But impersonation creates a lot of overhead on the server
The best solution to allow users of certain network groups is to deny anonymous in the web config
<authorization><deny users="?"/><authentication mode="Windows"/>
and in your code behind, preferably in the global.asax, use the HttpContext.Current.User.IsInRole :
Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
If HttpContext.Current.User.IsInRole("TheDomain\TheGroup") Then
//code to do when user is in group
End If
NOTE: The Group must be written with a backslash \ i.e. "TheDomain\TheGroup"
Firstly you need to install a SSH server in the images you wish to ssh-into. You can use a base image for all your container with the ssh server installed.
Then you only have to run each container mapping the ssh port (default 22) to one to the host's ports (Remote Server in your image), using -p <hostPort>:<containerPort>
. i.e:
docker run -p 52022:22 container1
docker run -p 53022:22 container2
Then, if ports 52022 and 53022 of host's are accessible from outside, you can directly ssh to the containers using the ip of the host (Remote Server) specifying the port in ssh with -p <port>
. I.e.:
ssh -p 52022 myuser@RemoteServer
--> SSH to container1
ssh -p 53022 myuser@RemoteServer
--> SSH to container2
There might be just a typo anywhere inside a file imported by the config. For example, I made a typo deep inside my config file:
loccation /sense/movies/ {
mp4;
}
(loccation instead of location), and this causes the error:
nginx: [emerg] "server" directive is not allowed here in /etc/nginx/sites-enabled/xxx.xx:1
If you made it to the bottom of the list. Save some php code and just bring everything back from the DB as you need like this:
$items = Standard::find()->select(['name'])->indexBy('s_id')->column();
Maybe unrelated to the original reason in this question, but for those who would face same with gradle and local module dependency
dependencies {
checkstyle project(":module")
}
this error could happen, if module doesn't contain group and version, so in the module/build.gradle
just need to be specified
plugins {
id 'java-library'
}
group = "com.example"
version = "master-SNAPSHOT"
If you really want the API you suggested, you could subclass HashMap and keep track of the keys in a List for example. Don't see the point in this really, but it gives you what you want. If you explain the intended use case, maybe we can come up with a better solution.
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
@SuppressWarnings("unchecked")
public class IndexedMap extends HashMap {
private List<Object> keyIndex;
public IndexedMap() {
keyIndex = new ArrayList<Object>();
}
/**
* Returns the key at the specified position in this Map's keyIndex.
*
* @param index
* index of the element to return
* @return the element at the specified position in this list
* @throws IndexOutOfBoundsException
* if the index is out of range (index < 0 || index >= size())
*/
public Object get(int index) {
return keyIndex.get(index);
}
@Override
public Object put(Object key, Object value) {
addKeyToIndex(key);
return super.put(key, value);
}
@Override
public void putAll(Map source) {
for (Object key : source.keySet()) {
addKeyToIndex(key);
}
super.putAll(source);
}
private void addKeyToIndex(Object key) {
if (!keyIndex.contains(key)) {
keyIndex.add(key);
}
}
@Override
public Object remove(Object key) {
keyIndex.remove(key);
return super.remove(key);
}
}
EDIT: I deliberately did not delve into the generics side of this...
Toward this same directions, I'm posting a client and server snipets that send Excel Files using WebApi, c# 4:
public static void SetFile(String serviceUrl, byte[] fileArray, String fileName)
{
try
{
using (var client = new HttpClient())
{
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
using (var content = new MultipartFormDataContent())
{
var fileContent = new ByteArrayContent(fileArray);//(System.IO.File.ReadAllBytes(fileName));
fileContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
FileName = fileName
};
content.Add(fileContent);
var result = client.PostAsync(serviceUrl, content).Result;
}
}
}
catch (Exception e)
{
//Log the exception
}
}
And the server webapi controller:
public Task<IEnumerable<string>> Post()
{
if (Request.Content.IsMimeMultipartContent())
{
string fullPath = HttpContext.Current.Server.MapPath("~/uploads");
MyMultipartFormDataStreamProvider streamProvider = new MyMultipartFormDataStreamProvider(fullPath);
var task = Request.Content.ReadAsMultipartAsync(streamProvider).ContinueWith(t =>
{
if (t.IsFaulted || t.IsCanceled)
throw new HttpResponseException(HttpStatusCode.InternalServerError);
var fileInfo = streamProvider.FileData.Select(i =>
{
var info = new FileInfo(i.LocalFileName);
return "File uploaded as " + info.FullName + " (" + info.Length + ")";
});
return fileInfo;
});
return task;
}
else
{
throw new HttpResponseException(Request.CreateResponse(HttpStatusCode.NotAcceptable, "Invalid Request!"));
}
}
And the Custom MyMultipartFormDataStreamProvider, needed to customize the Filename:
PS: I took this code from another post http://www.codeguru.com/csharp/.net/uploading-files-asynchronously-using-asp.net-web-api.htm
public class MyMultipartFormDataStreamProvider : MultipartFormDataStreamProvider
{
public MyMultipartFormDataStreamProvider(string path)

{
}
public override string GetLocalFileName(System.Net.Http.Headers.HttpContentHeaders headers)
{
string fileName;
if (!string.IsNullOrWhiteSpace(headers.ContentDisposition.FileName))
{
fileName = headers.ContentDisposition.FileName;
}
else
{
fileName = Guid.NewGuid().ToString() + ".data";
}
return fileName.Replace("\"", string.Empty);
}
}
This is basically a more detailed version of a previous answer.
In your Terminal, go to the location of your utility program, mysqladmin
For example, if you were doing local development and using an application like M/W/XAMP, you might go to the directory:
/Applications/MAMP/Library/bin
This is where mysqladmin resides.
If you're not using an application like MAMP, you may also be able to find your local installation of mysql at: /usr/local/mysql
And then if you go to: /usr/local/mysql/bin/
You are in the directory where mysqladmin resides.
Then, to change the password, you will do the following:
At your Terminal prompt enter the exact command below (aka copy and paste) and press enter. The word "password" is part of the command, so don't be confused and come to the conclusion that you need to replace this word with some password you created previously or want to use in the future. You will have a chance to enter a new password soon enough, but it's not in this first command that you will do that:
./mysqladmin -u root -p password
The Terminal will ask you to enter your original or initial password, not a new one yet. From the above image you provided, it looks like you have one already created, so enter it here:
Enter password:
oldpassword
New password:
newpassword
Confirm new password:
newpassword
Reset or restart your Terminal.
In some cases, as with M/W/XAMP, you will have to update this new password in various files in order to get your application running properly again.
The submodule approach is good if you want to maintain the project separately. However, if you really want to merge both projects into the same repository, then you have a bit more work to do.
The first thing would be to use git filter-branch
to rewrite the names of everything in the second repository to be in the subdirectory where you would like them to end up. So instead of foo.c
, bar.html
, you would have projb/foo.c
and projb/bar.html
.
Then, you should be able to do something like the following:
git remote add projb [wherever]
git pull projb
The git pull
will do a git fetch
followed by a git merge
. There should be no conflicts, if the repository you're pulling to does not yet have a projb/
directory.
Further searching indicates that something similar was done to merge gitk
into git
. Junio C Hamano writes about it here: http://www.mail-archive.com/[email protected]/msg03395.html
Try the change event and selected selector
$('#jobSel').change(function(){
var optId = $(this).find('option:selected').attr('id')
})
Angular.js has a built-in date filter.
// in your controller:
$scope.date = '20140313T00:00:00';
// in your view, date property, filtered with date filter and format 'MM/dd/yyyy'
<p ng-bind="date | date:'MM/dd/yyyy'"></p>
// produces
03/13/2014
You can see the supported date formats in the source for the date filter.
edit:
If you're trying to get the correct format in the datepicker (not clear if you're using datepicker or just trying to use it's formatter), those supported format strings are here: https://api.jqueryui.com/datepicker/
I give my solution for Mac:
If at any time you want to clear the log, type ./adb logcat -c
declare @OrderByCmd nvarchar(2000)
declare @OrderByName nvarchar(100)
declare @OrderByCity nvarchar(100)
set @OrderByName='Name'
set @OrderByCity='city'
set @OrderByCmd= 'select * from customer Order By '+@OrderByName+','+@OrderByCity+''
EXECUTE sp_executesql @OrderByCmd
Try this, may not be the best way. but it works
String str = "5 * x^3 - 6 * x^1 + 1";
str = str.replaceAll("(?x)(\\d+)(\\s+?\\*?\\s+?)(\\w+?)(\\^+?)(\\d+?)", "$1$3<sup>$5</sup>");
System.out.println(str);
I'll try and answer several different things, however my contribution may not cover all of your questions. Maybe several of us can take different chunks out of this. However, this info should be helpful for you. Here we go..
Opening A Seperate File:
ChDir "[Path here]" 'get into the right folder here
Workbooks.Open Filename:= "[Path here]" 'include the filename in this path
'copy data into current workbook or whatever you want here
ActiveWindow.Close 'closes out the file
Opening A File With Specified Date If It Exists:
I'm not sure how to search your directory to see if a file exists, but in my case I wouldn't bother to search for it, I'd just try to open it and put in some error checking so that if it doesn't exist then display this message or do xyz.
Some common error checking statements:
On Error Resume Next 'if error occurs continues on to the next line (ignores it)
ChDir "[Path here]"
Workbooks.Open Filename:= "[Path here]" 'try to open file here
Or (better option):
if one doesn't exist then bring up either a message box or dialogue box to say "the file does not exist, would you like to create a new one?
you would most likely want to use the GoTo ErrorHandler
shown below to achieve this
On Error GoTo ErrorHandler:
ChDir "[Path here]"
Workbooks.Open Filename:= "[Path here]" 'try to open file here
ErrorHandler:
'Display error message or any code you want to run on error here
Much more info on Error handling here: http://www.cpearson.com/excel/errorhandling.htm
Also if you want to learn more or need to know more generally in VBA I would recommend Siddharth Rout's site, he has lots of tutorials and example code here: http://www.siddharthrout.com/vb-dot-net-and-excel/
Hope this helps!
Example on how to ensure error code doesn't run EVERYtime:
if you debug through the code without the Exit Sub
BEFORE the error handler you'll soon realize the error handler will be run everytime regarldess of if there is an error or not. The link below the code example shows a previous answer to this question.
Sub Macro
On Error GoTo ErrorHandler:
ChDir "[Path here]"
Workbooks.Open Filename:= "[Path here]" 'try to open file here
Exit Sub 'Code will exit BEFORE ErrorHandler if everything goes smoothly
'Otherwise, on error, ErrorHandler will be run
ErrorHandler:
'Display error message or any code you want to run on error here
End Sub
Also, look at this other question in you need more reference to how this works: goto block not working VBA
Using ==
to compare two enum values works, because there is only one object for each enum constant.
On a side note, there is actually no need to use ==
to write null-safe code, if you write your equals()
like this:
public useEnums(final SomeEnum a) {
if (SomeEnum.SOME_ENUM_VALUE.equals(a)) {
…
}
…
}
This is a best practice known as Compare Constants From The Left that you definitely should follow.
You can add a specific url to each point, e.g.:
var points = [
['name1', 59.9362384705039, 30.19232525792222, 12, 'www.google.com'],
['name2', 59.941412822085645, 30.263564729357767, 11, 'www.amazon.com'],
['name3', 59.939177197629455, 30.273554411974955, 10, 'www.stackoverflow.com']
];
Add the url to the marker values in the for-loop:
var marker = new google.maps.Marker({
...
zIndex: place[3],
url: place[4]
});
Then you can add just before to the end of your for-loop:
google.maps.event.addListener(marker, 'click', function() {
window.location.href = this.url;
});
Also see this example.
Here is how you can easily remove the $$hashKey from the object:
$scope.myNewObject = JSON.parse(angular.toJson($scope.myObject))
$scope.myObject
- Refers to the Object that you want to perform the operation upon i.e. remove the $$hashKey from
$scope.myNewObject
- Assign the modified original object to the new object so it can be used as necessary
With bash
a="The cat sat on the mat"
b=cat
strindex() {
x="${1%%$2*}"
[[ "$x" = "$1" ]] && echo -1 || echo "${#x}"
}
strindex "$a" "$b" # prints 4
strindex "$a" foo # prints -1
best explanation of Cohesion comes from Uncle Bob's Clean Code:
Classes should have a small number of instance variables. Each of the methods of a class should manipulate one or more of those variables. In general the more variables a method manipulates the more cohesive that method is to its class. A class in which each variable is used by each method is maximally cohesive.
In general it is neither advisable nor possible to create such maximally cohesive classes; on the other hand, we would like cohesion to be high. When cohesion is high, it means that the methods and variables of the class are co-dependent and hang together as a logical whole.
The strategy of keeping functions small and keeping parameter lists short can sometimes lead to a proliferation of instance variables that are used by a subset of methods. When this happens, it almost always means that there is at least one other class trying to get out of the larger class. You should try to separate the variables and methods into two or more classes such that the new classes are more cohesive.
How I can get rid of it so it doesnt display it?
People here are trying to tell you that it's unprofessional (and it is), but in your case you should simply add following to the start of your application:
error_reporting(E_ERROR|E_WARNING);
This will disable E_NOTICE reporting. E_NOTICES are not errors, but notices, as the name says. You'd better check this stuff out and proof that undefined variables don't lead to errors. But the common case is that they are just informal, and perfectly normal for handling form input with PHP.
Also, next time Google the error message first.
You don't need a library beyond the standard one - just use Charset. (You can just use the String constructors and getBytes methods, but personally I don't like just working with the names of character encodings. Too much room for typos.)
EDIT: As pointed out in comments, you can still use Charset instances but have the ease of use of the String methods: new String(bytes, charset) and String.getBytes(charset).
See "URL Encoding (or: 'What are those "%20
" codes in URLs?')".
a very common try_files line which can be applied on your condition is
location / {
try_files $uri $uri/ /test/index.html;
}
you probably understand the first part, location /
matches all locations, unless it's matched by a more specific location, like location /test
for example
The second part ( the try_files
) means when you receive a URI that's matched by this block try $uri
first, for example http://example.com/images/image.jpg
nginx will try to check if there's a file inside /images
called image.jpg
if found it will serve it first.
Second condition is $uri/
which means if you didn't find the first condition $uri
try the URI as a directory, for example http://example.com/images/
, ngixn will first check if a file called images
exists then it wont find it, then goes to second check $uri/
and see if there's a directory called images
exists then it will try serving it.
Side note: if you don't have autoindex on
you'll probably get a 403 forbidden error, because directory listing is forbidden by default.
EDIT: I forgot to mention that if you have
index
defined, nginx will try to check if the index exists inside this folder before trying directory listing.
Third condition /test/index.html
is considered a fall back option, (you need to use at least 2 options, one and a fall back), you can use as much as you can (never read of a constriction before), nginx will look for the file index.html
inside the folder test
and serve it if it exists.
If the third condition fails too, then nginx will serve the 404 error page.
Also there's something called named locations, like this
location @error {
}
You can call it with try_files
like this
try_files $uri $uri/ @error;
TIP: If you only have 1 condition you want to serve, like for example inside folder images
you only want to either serve the image or go to 404 error, you can write a line like this
location /images {
try_files $uri =404;
}
which means either serve the file or serve a 404 error, you can't use only $uri
by it self without =404
because you need to have a fallback option.
You can also choose which ever error code you want, like for example:
location /images {
try_files $uri =403;
}
This will show a forbidden error if the image doesn't exist, or if you use 500 it will show server error, etc ..
Well, longs can't hold anything but integers.
One option is to use a float: float('234.89')
The other option is to truncate or round. Converting from a float to a long will truncate for you: long(float('234.89'))
>>> long(float('1.1'))
1L
>>> long(float('1.9'))
1L
>>> long(round(float('1.1')))
1L
>>> long(round(float('1.9')))
2L

Give hibernate.connection.url
as "jdbc:oracle:thin:@127.0.0.1:1521:xe"
then you can solve above issue. Because oracle's default SID is "xe" so we should give like this. When I gave like this data has been inserted into DB without any SQL exceptions, it's my real time experience.
hash_map is a non-standard extension. unordered_map is part of std::tr1, and will be moved into the std namespace for C++0x. http://en.wikipedia.org/wiki/Unordered_map_%28C%2B%2B%29
Here a single example using Duration and TimeUnit to get 'hh:mm:ss' format.
Duration dur = Duration.between(localDateTimeIni, localDateTimeEnd);
long millis = dur.toMillis();
String.format("%02d:%02d:%02d",
TimeUnit.MILLISECONDS.toHours(millis),
TimeUnit.MILLISECONDS.toMinutes(millis) -
TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
TimeUnit.MILLISECONDS.toSeconds(millis) -
TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));
Because there are two print statements. First is inside function and second is outside function. When function not return any thing that time it return None value.
Use return
statement at end of function to return value.
e.g.:
Return None value.
>>> def test1():
... print "In function."
...
>>> a = test1()
In function.
>>> print a
None
>>>
>>> print test1()
In function.
None
>>>
>>> test1()
In function.
>>>
Use return statement
>>> def test():
... return "ACV"
...
>>> print test()
ACV
>>>
>>> a = test()
>>> print a
ACV
>>>
For those of you that are looking for a way to install Maven in 2018:

I think all solutions will fail if the length of the replacing string is different from the length of the string to be replaced. (search for "abc" and replace by "xxxxxx") A general approach might be:
void replaceAll( string &s, const string &search, const string &replace ) {
for( size_t pos = 0; ; pos += replace.length() ) {
// Locate the substring to replace
pos = s.find( search, pos );
if( pos == string::npos ) break;
// Replace by erasing and inserting
s.erase( pos, search.length() );
s.insert( pos, replace );
}
}
This does not address the main question, but one nice trick to get the last weekday in a month is to use calendar.monthcalendar
, which returns a matrix of dates, organized with Monday as the first column through Sunday as the last.
# Some random date.
some_date = datetime.date(2012, 5, 23)
# Get last weekday
last_weekday = np.asarray(calendar.monthcalendar(some_date.year, some_date.month))[:,0:-2].ravel().max()
print last_weekday
31
The whole [0:-2]
thing is to shave off the weekend columns and throw them out. Dates that fall outside of the month are indicated by 0, so the max effectively ignores them.
The use of numpy.ravel
is not strictly necessary, but I hate relying on the mere convention that numpy.ndarray.max
will flatten the array if not told which axis to calculate over.
Another server you can try http://tjws.sf.net, actually it already provides Android enabled version.
you can directly give the Image name in your setimage as iv.setImageResource(R.drawable.apple);
that should be it.

There is another answer that I thought might be a good addition to this list.
If you have perl
installed and are able to run things from the shell in PHP:
$lines = exec('perl -pe \'s/\r\n|\n|\r/\n/g\' ' . escapeshellarg('largetextfile.txt') . ' | wc -l');
This should handle most line breaks whether from Unix or Windows created files.
TWO downsides (at least):
1) It is not a great idea to have your script so dependent upon the system its running on ( it may not be safe to assume Perl and wc are available )
2) Just a small mistake in escaping and you have handed over access to a shell on your machine.
As with most things I know (or think I know) about coding, I got this info from somewhere else:
In my case i just needed to pass the whole url and encode only the value of each parameters. I didn't find a common code to do that so (!!) so i created this small method to do the job :
public static String encodeUrl(String url) throws Exception {
if (url == null || !url.contains("?")) {
return url;
}
List<String> list = new ArrayList<>();
String rootUrl = url.split("\\?")[0] + "?";
String paramsUrl = url.replace(rootUrl, "");
List<String> paramsUrlList = Arrays.asList(paramsUrl.split("&"));
for (String param : paramsUrlList) {
if (param.contains("=")) {
String key = param.split("=")[0];
String value = param.replace(key + "=", "");
list.add(key + "=" + URLEncoder.encode(value, "UTF-8"));
}
else {
list.add(param);
}
}
return rootUrl + StringUtils.join(list, "&");
}
public static String decodeUrl(String url) throws Exception {
return URLDecoder.decode(url, "UTF-8");
}
It uses org.apache.commons.lang3.StringUtils
Shell calls to reverse (as mentioned above) are very good to debug these problems, but there are two critical conditions:
Yes, it's logical. Yes, it's also confusing because reverse will only throw the exception and won't give you any further hints.
An example of URL pattern:
url(r'^cookies/(?P<hostname>[^/]+)/(?P<url_id>\d+)/$', 'register_site.views.show_cookies', name='show_cookies'),
And then what happens in shell:
>>> from register_site.views import show_cookies
>>> reverse(show_cookies)
NoReverseMatch: Reverse for 'register_site.views.show_cookies' with arguments '()' and keyword arguments '{}' not found.
It doesn't work because I supplied no arguments.
>>> reverse('show_cookies', kwargs={'url_id':123,'hostname': 'aaa'})
'/cookies/aaa/123'
Now it worked, but...
>>> reverse('show_cookies', kwargs={'url_id':'x','hostname': 'www.dupa.com'})
NoReverseMatch: Reverse for 'show_cookies' with arguments '()' and keyword arguments '{'url_id': 'x', 'hostname': 'www.dupa.com'}' not found.
Now it didn't work because url_id didn't match the regexp (expected numeric, supplied string).
You can use reverse with both positional arguments and keyword arguments. The syntax is:
reverse(viewname, urlconf=None, args=None, kwargs=None, prefix=None, current_app=None)
As it comes to the url template tag, there's funny thing about it. Django documentation gives example of using quoted view name:
{% url 'news.views.year_archive' yearvar %}
So I used it in a similar way in my HTML template:
{% url 'show_cookies' hostname=u.hostname url_id=u.pk %}
But this didn't work for me. But the exception message gave me a hint of what could be wrong - note the double single quotes around view name:
Reverse for ''show_cookies'' with arguments...
It started to work when I removed the quotes:
{% url show_cookies hostname=u.hostname url_id=u.pk %}
And this is confusing.
Try below function:
public static String getFormattedDate(Date date)
{
Calendar cal = Calendar.getInstance();
cal.setTime(date);
//2nd of march 2015
int day = cal.get(Calendar.DATE);
if (!((day > 10) && (day < 19)))
switch (day % 10) {
case 1:
return new SimpleDateFormat("d'st' 'of' MMMM yyyy").format(date);
case 2:
return new SimpleDateFormat("d'nd' 'of' MMMM yyyy").format(date);
case 3:
return new SimpleDateFormat("d'rd' 'of' MMMM yyyy").format(date);
default:
return new SimpleDateFormat("d'th' 'of' MMMM yyyy").format(date);
}
return new SimpleDateFormat("d'th' 'of' MMMM yyyy").format(date);
}
`n
is a line feed character. Notepad (prior to Windows 10) expects linebreaks to be encoded as `r`n
(carriage return + line feed, CR-LF). Open the file in some useful editor (SciTE, Notepad++, UltraEdit-32, Vim, ...) and convert the linebreaks to CR-LF. Or use PowerShell:
(Get-Content $logpath | Out-String) -replace "`n", "`r`n" | Out-File $logpath
yes you can do it. write this code on your typescript component and enjoy!
import { Location } from '@angular/common'
import { Component, Input } from '@angular/core'
@Component({
selector: 'return_page',
template: `<button mat-button (click)="onReturn()">Back</button>`,
})
export class ReturnPageComponent {
constructor(private location: Location) { }
onReturn() {
this.location.back();
}
}
If you've upgraded to Mac OS X 10.8 Mountain Lion, and previously had a working system, all you should need to do is re-enable PHP as in Step 1 of the above chosen answer.
You may also find the following Preference Pane useful for managing "web sharing" (Apache web server), which replaces system functionality removed in OS X 10.8: http://clickontyler.com/blog/2012/02/web-sharing-mountain-lion/
I also had to re-add my virtual hosts include line to the httpd.conf
I think you are asking about code like this.
int count = (request.getParameter("counter") == null) ? 0 : Integer.parseInt(request.getParameter("counter"));
I think you should re-format your code a bit:
#!/bin/bash

mkdir -p /home/mlzboy/b2c2/shared/db;
fi;

First thing's first, if your dates are in varchar format change that, store dates as dates it will save you a lot of headaches and it is something that is best done sooner rather than later. The problem will only get worse.
Secondly, once you have a date DO NOT convert the date to a varchar! Keep it in date format and use formatting on the application side to get the required date format.
There are various methods to do this depending on your DBMS:
SQL-Server 2008 and later:
SELECT CAST(CURRENT_TIMESTAMP AS DATE)
SQL-Server 2005 and Earlier
SELECT DATEADD(DAY, DATEDIFF(DAY, 0, CURRENT_TIMESTAMP), 0)
SQLite
SELECT DATE(NOW())
Oracle
SELECT TRUNC(CURRENT_TIMESTAMP)
Postgresql
SELECT CURRENT_TIMESTAMP::DATE
If you need to use culture specific formatting in your report you can either explicitly state the format of the receiving text box (e.g. dd/MM/yyyy), or you can set the language so that it shows the relevant date format for that language.
Either way this is much better handled outside of SQL as converting to varchar within SQL will impact any sorting you may do in your report.
If you cannot/will not change the datatype to DATETIME, then still convert it to a date within SQL (e.g. CONVERT(DATETIME, yourField)
) before sending to report services and handle it as described above.
You will find much information about JavaDoc at the Documentation Comment Specification for the Standard Doclet, including the information on the
tag (that you are looking for). The corresponding example from the documentation is as follows
For example, here is a comment that refers to the getComponentAt(int, int) method:
Use the {@link #getComponentAt(int, int) getComponentAt} method.
The package.class
part can be ommited if the referred method is in the current class.

I am using a com.google.android.material.bottomnavigation.BottomNavigationView
(not the same as OP's) and I tried a variety of the suggested solutions above, but the only thing that worked was setting app:itemBackground
and app:itemIconTint
to my selector color worked for me.
<com.google.android.material.bottomnavigation.BottomNavigationView
style="@style/BottomNavigationView"
android:foreground="?attr/selectableItemBackground"
android:theme="@style/BottomNavigationView"
app:itemBackground="@color/tab_color"
app:itemIconTint="@color/tab_color"
app:itemTextColor="@color/bottom_navigation_text_color"
app:labelVisibilityMode="labeled"
app:menu="@menu/bottom_navigation" />
My color/tab_color.xml
uses android:state_checked
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="@color/grassSelected" android:state_checked="true" />
<item android:color="@color/grassBackground" />
</selector>
and I am also using a selected state color for color/bottom_navigation_text_color.xml
Not totally relevant here but for full transparency, my BottomNavigationView
style is as follows:
<style name="BottomNavigationView" parent="Widget.Design.BottomNavigationView">
<item name="android:layout_width">match_parent</item>
<item name="android:layout_height">@dimen/bottom_navigation_height</item>
<item name="android:layout_gravity">bottom</item>
<item name="android:textSize">@dimen/bottom_navigation_text_size</item>
</style>
$("input[name='RadioTest'][value='2']").prop('checked', true);
I used this conversion:
CString cs = "TEST";
char* c = cs.GetBuffer(m_ncs me.GetLength())
I hope this is useful.
Try to follow the advice you see on the screen, and first reset your master's HEAD to the commit it expects.
git update-ref refs/heads/master b918ac16a33881ce00799bea63d9c23bf7022d67
Then, abort the rebase again.
Perhaps you need to specify a top value in your css rule set, so that it will know what value to animate from.
If there is space between the letters of the font, you need to use quote.
font-family:"Calibri (Body)";
Tested libraries like Imagemagick and GD are available for .NET
You could also read up on things like bicubic interpolation and write your own.

The difference between npm install and npm update handling of package versions specified in package.json:
{
"name": "my-project",
"version": "1.0", // install update
"dependencies": { // ------------------
"already-installed-versionless-module": "*", // ignores "1.0" -> "1.1"
"already-installed-semver-module": "^1.4.3" // ignores "1.4.3" -> "1.5.2"
"already-installed-versioned-module": "3.4.1" // ignores ignores
"not-yet-installed-versionless-module": "*", // installs installs
"not-yet-installed-semver-module": "^4.2.1" // installs installs
"not-yet-installed-versioned-module": "2.7.8" // installs installs
}
}
Summary: The only big difference is that an already installed module with fuzzy versioning ...
npm install
npm update
Additionally: install
and update
by default handle devDependencies differently
npm install
will install/update devDependencies unless --production
flag is addednpm update
will ignore devDependencies unless --dev
flag is addedWhy use npm install
at all?
Because npm install
does more when you look besides handling your dependencies in package.json
.
As you can see in npm install you can ...

Lets take fibonacci series as an example
1,1,2,3,5,8,13,21....
first number: 1
Second number: 1
Third Number: 2
Another way to put it,
Bottom(first) number: 1
Top (Eighth) number on the given sequence: 21
In case of first five fibonacci number
Bottom(first) number :1
Top (fifth) number: 5
Now lets take a look of recursive Fibonacci series algorithm as an example
public int rcursive(int n) {
if ((n == 1) || (n == 2)) {
return 1;
} else {
return rcursive(n - 1) + rcursive(n - 2);
}
}
Now if we execute this program with following commands
rcursive(5);
if we closely look into the algorithm, in-order to generate fifth number it requires 3rd and 4th numbers. So my recursion actually start from top(5) and then goes all the way to bottom/lower numbers. This approach is actually top-down approach.
To avoid doing same calculation multiple times we use Dynamic Programming techniques. We store previously computed value and reuse it. This technique is called memoization. There are more to Dynamic programming other then memoization which is not needed to discuss current problem.
Top-Down
Lets rewrite our original algorithm and add memoized techniques.
public int memoized(int n, int[] memo) {
if (n <= 2) {
return 1;
} else if (memo[n] != -1) {
return memo[n];
} else {
memo[n] = memoized(n - 1, memo) + memoized(n - 2, memo);
}
return memo[n];
}
And we execute this method like following
int n = 5;
int[] memo = new int[n + 1];
Arrays.fill(memo, -1);
memoized(n, memo);
This solution is still top-down as algorithm start from top value and go to bottom each step to get our top value.
Bottom-Up
But, question is, can we start from bottom, like from first fibonacci number then walk our way to up. Lets rewrite it using this techniques,
public int dp(int n) {
int[] output = new int[n + 1];
output[1] = 1;
output[2] = 1;
for (int i = 3; i <= n; i++) {
output[i] = output[i - 1] + output[i - 2];
}
return output[n];
}
Now if we look into this algorithm it actually start from lower values then go to top. If i need 5th fibonacci number i am actually calculating 1st, then second then third all the way to up 5th number. This techniques actually called bottom-up techniques.
Last two, algorithms full-fill dynamic programming requirements. But one is top-down and another one is bottom-up. Both algorithm has similar space and time complexity.
