There is a class, Class
, that can do this:
Class c = Class.forName("MyClass"); // if you want to specify a class
Class c = this.getClass(); // if you want to use the current class
System.out.println("Package: "+c.getPackage()+"\nClass: "+c.getSimpleName()+"\nFull Identifier: "+c.getName());
If c
represented the class MyClass
in the package mypackage
, the above code would print:
Package: mypackage
Class: MyClass
Full Identifier: mypackage.MyClass
You can take this information and modify it for whatever you need, or go check the API for more information.
As per the HTML:
<html>
<body>
<p class="content">Link1.</p>
</body>
<html>
<html>
<body>
<p class="content">Link2.</p>
</body>
<html>
Two(2) <p>
elements are having the same class content
.
So to filter the elements having the same class i.e. content
and create a list you can use either of the following Locator Strategies:
Using class_name
:
elements = driver.find_elements_by_class_name("content")
Using css_selector
:
elements = driver.find_elements_by_css_selector(".content")
Using xpath
:
elements = driver.find_elements_by_xpath("//*[@class='content']")
Ideally, to click on the element you need to induce WebDriverWait for the visibility_of_all_elements_located()
and you can use either of the following Locator Strategies:
Using CLASS_NAME
:
elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CLASS_NAME, "content")))
Using CSS_SELECTOR
:
elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, ".content")))
Using XPATH
:
elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//*[@class='content']")))
Note : You have to add the following imports :
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
You can find a couple of relevant discussions in:
I'm assuming this is happening for an anonymous class. When you create an anonymous class you actually create a class that extends the class whose name you got.
The "cleaner" way to get the name you want is:
If your class is an anonymous inner class, getSuperClass()
should give you the class that it was created from. If you created it from an interface than you're sort of SOL because the best you can do is getInterfaces()
which might give you more than one interface.
The "hacky" way is to just get the name with getClassName()
and use a regex to drop the $1
.
myImg.Source = new BitmapImage(new Uri(@"component/Images/down.png", UriKind.RelativeOrAbsolute));
Don't forget to set Build Action to "Content", and Copy to output directory to "Always".
A little background information:
As said, if you want to have a dynamic collection of things, use a List<T>
. Internally, a List uses an array for storage too. That array has a fixed size just like any other array. Once an array is declared as having a size, it doesn't change. When you add an item to a List
, it's added to the array. Initially, the List
starts out with an array that I believe has a length of 16. When you try to add the 17th item to the List
, what happens is that a new array is allocated, that's (I think) twice the size of the old one, so 32 items. Then the content of the old array is copied into the new array. So while a List
may appear dynamic to the outside observer, internally it has to comply to the rules as well.
And as you might have guessed, the copying and allocation of the arrays isn't free so one should aim to have as few of those as possible and to do that you can specify (in the constructor of List
) an initial size of the array, which in a perfect scenario is just big enough to hold everything you want. However, this is micro-optimization and it's unlikely it will ever matter to you, but it's always nice to know what you're actually doing.
If your path
environment variable contains Python (eg. C:\Python27\
) you can run your py file simply from Windows command line (cmd).
Howto here.
#include <iostream>
#include <cstdio>
#include <ctime>
int main() {
std::clock_t start;
double duration;
start = std::clock();
/* Your algorithm here */
duration = ( std::clock() - start ) / (double) CLOCKS_PER_SEC;
std::cout<<"printf: "<< duration <<'\n';
}
Yes, this is related to new updates in safari that are breaking your layout now if you use overflow: hidden to take care of clearing divs.
Wrap it in double quotes
alter user "dell-sys" with password 'Pass@133';
Notice that you will have to use the same case you used when you created the user using double quotes. Say you created "Dell-Sys"
then you will have to issue exact the same whenever you refer to that user.
I think the best you do is to drop that user and recreate without illegal identifier characters and without double quotes so you can later refer to it in any case you want.
You need to give required = false
for name
and password
request parameters as well. That's because, when you provide just the logout
parameter, it actually expects for name
and password
as well as they are still mandatory.
It worked when you just gave name
and password
because logout
wasn't a mandatory parameter thanks to required = false
already given for logout
.
The answer is explained here.
To quote:
A class is free to implement comparison any way it chooses, and it can choose to make comparison against None mean something (which actually makes sense; if someone told you to implement the None object from scratch, how else would you get it to compare True against itself?).
Practically-speaking, there is not much difference since custom comparison operators are rare. But you should use is None
as a general rule.
My issue was related to using multiple accounts. This is how I was able to switch accounts.
Open Team Explorer
From the big drop down menu near the top of the pane...
Navigate to: Projects and my Teams>Manage Connections
Navigate to: Manage Connections>Connect to Team Project
Use the "Switch User" link to switch accounts.
Now the workspace names will match the chosen account.
The guide by Ani Menon (thx!) almost worked for me on windows 10, i just had to get a newer winutils.exe off that git (currently hadoop-2.8.1): https://github.com/steveloughran/winutils
Try this I learned this from @nmaier when I was mucking around with converting to ico: Well i dont really understand what array buffer is but it does what we need:
function previewFile(file) {
var reader = new FileReader();
reader.onloadend = function () {
console.log(reader.result); //this is an ArrayBuffer
}
reader.readAsArrayBuffer(file);
}
notice how i just changed your readAsDataURL
to readAsArrayBuffer
.
Here is the example @nmaier gave me: https://stackoverflow.com/a/24253997/1828637
it has a fiddle
if you want to take this and make a file out of it i would think you would use file-output-stream in the onloadend
You would usually use map for that kind of thing.
buttonsListArr = initialArr.map(buttonInfo => (
<Button ... key={buttonInfo[0]}>{buttonInfo[1]}</Button>
);
(key is a necessary prop whenever you do mapping in React. The key needs to be a unique identifier for the generated component)
As a side, I would use an object instead of an array. I find it looks nicer:
initialArr = [
{
id: 1,
color: "blue",
text: "text1"
},
{
id: 2,
color: "red",
text: "text2"
},
];
buttonsListArr = initialArr.map(buttonInfo => (
<Button ... key={buttonInfo.id}>{buttonInfo.text}</Button>
);
cp dir1/* dir2
Or if you have directories inside dir1 that you'd want to copy as well
cp -r dir1/* dir2
echo '< span style = "font-color: #ff0000"> Movie List for {$key} 2013 </span>';
From the id Selector jQuery page:
Each id value must be used only once within a document. If more than one element has been assigned the same ID, queries that use that ID will only select the first matched element in the DOM. This behavior should not be relied on, however; a document with more than one element using the same ID is invalid.
Naughty Google. But they don't even close their <html>
and <body>
tags I hear. The question is though, why Misha's 2nd and 3rd queries return 2 and not 1 as well.
I use []
.
If you are using Java 8 then try this using lambda expression and org.apache.commons.lang.StringUtils, that will also clear null
and blank
values from array
input
public static String[] cleanArray(String[] array) {
return Arrays.stream(array).filter(x -> !StringUtils.isBlank(x)).toArray(String[]::new);
}
Clean and Simple:
$('#signup').submit(function(event) {
alert(this.action);
});
This way worked very well in my situation. I just added some modifications based on other code presented in this thread.
import sys, os
orig_stdout = sys.stdout # capture original state of stdout
te = open('log.txt','w') # File where you need to keep the logs
class Unbuffered:
def __init__(self, stream):
self.stream = stream
def write(self, data):
self.stream.write(data)
self.stream.flush()
te.write(data) # Write the data of stdout here to a text file as well
sys.stdout=Unbuffered(sys.stdout)
#######################################
## Feel free to use print function ##
#######################################
print("Here is an Example =)")
#######################################
## Feel free to use print function ##
#######################################
# Stop capturing printouts of the application from Windows CMD
sys.stdout = orig_stdout # put back the original state of stdout
te.flush() # forces python to write to file
te.close() # closes the log file
# read all lines at once and capture it to the variable named sys_prints
with open('log.txt', 'r+') as file:
sys_prints = file.readlines()
# erase the file contents of log file
open('log.txt', 'w').close()
Use position: fixed
, and anchor it to the top
and right
sides of the page:
#fixed-div {
position: fixed;
top: 1em;
right: 1em;
}
IE6 does not support position: fixed
, however. If you need this functionality in IE6, this purely-CSS solution seems to do the trick. You'll need a wrapper <div>
to contain some of the styles for it to work, as seen in the stylesheet.
Works with Express 4.x :
The Correct way to include partials in the template according to this you should use:
<%- include('partials/youFileName.ejs') %>
.
You are using:
<% include partials/yourFileName.ejs %>
which is deprecated.
you can simply use rstrip:
for stuff in largestring:
print(stuff.rstrip("\n")
I searched a lot for a, easy to digest, algorithm to calculate the working days between 2 dates, and also to exclude the national holidays, and finally I decide to go with this approach:
public static int NumberOfWorkingDaysBetween2Dates(DateTime start,DateTime due,IEnumerable<DateTime> holidays)
{
var dic = new Dictionary<DateTime, DayOfWeek>();
var totalDays = (due - start).Days;
for (int i = 0; i < totalDays + 1; i++)
{
if (!holidays.Any(x => x == start.AddDays(i)))
dic.Add(start.AddDays(i), start.AddDays(i).DayOfWeek);
}
return dic.Where(x => x.Value != DayOfWeek.Saturday && x.Value != DayOfWeek.Sunday).Count();
}
Basically I wanted to go with each date and evaluate my conditions:
but also I wanted to avoid iterating dates.
By running and measuring the time need it to evaluate 1 full year, I go the following result:
static void Main(string[] args)
{
var start = new DateTime(2017, 1, 1);
var due = new DateTime(2017, 12, 31);
var sw = Stopwatch.StartNew();
var days = NumberOfWorkingDaysBetween2Dates(start, due,NationalHolidays());
sw.Stop();
Console.WriteLine($"Total working days = {days} --- time: {sw.Elapsed}");
Console.ReadLine();
// result is:
// Total working days = 249-- - time: 00:00:00.0269087
}
Edit: a new method more simple:
public static int ToBusinessWorkingDays(this DateTime start, DateTime due, DateTime[] holidays)
{
return Enumerable.Range(0, (due - start).Days)
.Select(a => start.AddDays(a))
.Where(a => a.DayOfWeek != DayOfWeek.Sunday)
.Where(a => a.DayOfWeek != DayOfWeek.Saturday)
.Count(a => !holidays.Any(x => x == a));
}
Few months ago, I implemented a way to determine if any string is integer, hexadecimal or double.
enum{
STRING_IS_INVALID_NUMBER=0,
STRING_IS_HEXA,
STRING_IS_INT,
STRING_IS_DOUBLE
};
bool isDigit(char c){
return (('0' <= c) && (c<='9'));
}
bool isHexaDigit(char c){
return ((('0' <= c) && (c<='9')) || ((tolower(c)<='a')&&(tolower(c)<='f')));
}
char *ADVANCE_DIGITS(char *aux_p){
while(CString::isDigit(*aux_p)) aux_p++;
return aux_p;
}
char *ADVANCE_HEXADIGITS(char *aux_p){
while(CString::isHexaDigit(*aux_p)) aux_p++;
return aux_p;
}
int isNumber(const string & test_str_number){
bool isHexa=false;
char *str = (char *)test_str_number.c_str();
switch(*str){
case '-': str++; // is negative number ...
break;
case '0':
if(tolower(*str+1)=='x') {
isHexa = true;
str+=2;
}
break;
default:
break;
};
char *start_str = str; // saves start position...
if(isHexa) { // candidate to hexa ...
str = ADVANCE_HEXADIGITS(str);
if(str == start_str)
return STRING_IS_INVALID_NUMBER;
if(*str == ' ' || *str == 0)
return STRING_IS_HEXA;
}else{ // test if integer or float
str = ADVANCE_DIGITS(str);
if(*str=='.') { // is candidate to double
str++;
str = ADVANCE_DIGITS(str);
if(*str == ' ' || *str == 0)
return STRING_IS_DOUBLE;
return STRING_IS_INVALID_NUMBER;
}
if(*str == ' ' || *str == 0)
return STRING_IS_INT;
}
return STRING_IS_INVALID_NUMBER;
}
Then in your program you can easily convert the number in function its type if you do the following,
string val; // the string to check if number...
switch(isNumber(val)){
case STRING_IS_HEXA:
// use strtol(val.c_str(), NULL, 16); to convert it into conventional hexadecimal
break;
case STRING_IS_INT:
// use (int)strtol(val.c_str(), NULL, 10); to convert it into conventional integer
break;
case STRING_IS_DOUBLE:
// use atof(val.c_str()); to convert it into conventional float/double
break;
}
You can realise that the function will return a 0 if the number wasn't detected. The 0 it can be treated as false (like boolean).
I don't know how it crazy it looks but it does the job really well
ascii2hex(){ a="$@";s=0000000;printf "$a" | hexdump | grep "^$s"| sed s/' '//g| sed s/^$s//;}
Created this when I was trying to see my name in HEX ;) use how can you use it :)
Discord doesn't allow colored text. Though, currently, you have two options to "mimic" colored text.
Discord supports Markdown and uses highlight.js to highlight code-blocks.
Some programming languages have specific color outputs from highlight.js and can be used to mimic colored output.
To use code-blocks, send a normal message in this format (Which follows Markdown's standard format).
```language
message
```
Languages that currently reproduce nice colors: prolog (red/orange), css (yellow).
Discord now supports Embeds and Webhooks, which can be used to display colored blocks, they also support markdown. For documentation on how to use Embeds, please read your lib's documentation.
Thanks! @steovi for this solution.
I have added support to ES6 version and changed from unescape to dataURI(unescape is deprecated).
converterDataURItoBlob(dataURI) {
let byteString;
let mimeString;
let ia;
if (dataURI.split(',')[0].indexOf('base64') >= 0) {
byteString = atob(dataURI.split(',')[1]);
} else {
byteString = encodeURI(dataURI.split(',')[1]);
}
// separate out the mime component
mimeString = dataURI.split(',')[0].split(':')[1].split(';')[0];
// write the bytes of the string to a typed array
ia = new Uint8Array(byteString.length);
for (var i = 0; i < byteString.length; i++) {
ia[i] = byteString.charCodeAt(i);
}
return new Blob([ia], {type:mimeString});
}
The problem in your case is the ItemSerializer is missing the method handledType() which needs to be overridden from JsonSerializer
public class ItemSerializer extends JsonSerializer<Item> {
@Override
public void serialize(Item value, JsonGenerator jgen,
SerializerProvider provider) throws IOException,
JsonProcessingException {
jgen.writeStartObject();
jgen.writeNumberField("id", value.id);
jgen.writeNumberField("itemNr", value.itemNr);
jgen.writeNumberField("createdBy", value.user.id);
jgen.writeEndObject();
}
@Override
public Class<Item> handledType()
{
return Item.class;
}
}
Hence you are getting the explicit error that handledType() is not defined
Exception in thread "main" java.lang.IllegalArgumentException: JsonSerializer of type com.example.ItemSerializer does not define valid handledType()
Hope it helps someone. Thanks for reading my answer.
Not sure why this works but dynamic (or wildcard if you prefer) routes are possible in angular 1.2.0-rc.2...
http://code.angularjs.org/1.2.0-rc.2/angular.min.js
http://code.angularjs.org/1.2.0-rc.2/angular-route.min.js
angular.module('yadda', [
'ngRoute'
]).
config(function ($routeProvider, $locationProvider) {
$routeProvider.
when('/:a', {
template: '<div ng-include="templateUrl">Loading...</div>',
controller: 'DynamicController'
}).
controller('DynamicController', function ($scope, $routeParams) {
console.log($routeParams);
$scope.templateUrl = 'partials/' + $routeParams.a;
}).
example.com/foo -> loads "foo" partial
example.com/bar-> loads "bar" partial
No need for any adjustments in the ng-view. The '/:a' case is the only variable I have found that will acheive this.. '/:foo' does not work unless your partials are all foo1, foo2, etc... '/:a' works with any partial name.
All values fire the dynamic controller - so there is no "otherwise" but, I think it is what you're looking for in a dynamic or wildcard routing scenario..
My gem version 2.0.3 and I was getting the same issue. This command resolved it:
gem install json --platform=ruby --verbose
Import cars data
import pandas as pd
cars = pd.read_csv('cars.csv', index_col = 0)
Here is how the cars.csv file looks.
Print out drives_right column as Series:
print(cars.loc[:,"drives_right"])
US True
AUS False
JAP False
IN False
RU True
MOR True
EG True
Name: drives_right, dtype: bool
The single bracket version gives a Pandas Series, the double bracket version gives a Pandas DataFrame.
Print out drives_right column as DataFrame
print(cars.loc[:,["drives_right"]])
drives_right
US True
AUS False
JAP False
IN False
RU True
MOR True
EG True
Adding a Series to another Series creates a DataFrame.
If anyone comes here after me, this is the answer that worked for me.
NOTE: please make to read the comments before using this, this not complete. The best advice for update queries I can give is to switch to SqlServer ;)
update mytable t
set z = (
with comp as (
select b.*, 42 as computed
from mytable t
where bs_id = 1
)
select c.computed
from comp c
where c.id = t.id
)
Good luck,

I was trying the verb = "runas"
, but I still was getting UnauthorizedAccessException when trying to update registry value. Turned out it was due to not opening the subkey with writeable set to true.
Registry.OpenSubKey("KeyName", true);
Cannot write to Registry Key, getting UnauthorizedAccessException
#since this was yesterday
date -dyesterday +%Y%m%d
#more precise, and more recommended
date -d'27 JUN 2011' +%Y%m%d
#assuming this is similar to yesterdays `date` question from you
#http://stackoverflow.com/q/6497525/638649
date -d'last-monday' +%Y%m%d
#going on @seth's comment you could do this
DATE="27 jun 2011"; date -d"$DATE" +%Y%m%d
#or a method to read it from stdin
read -p " Get date >> " DATE; printf " AS YYYYMMDD format >> %s" `date
-d"$DATE" +%Y%m%d`
#which then outputs the following:
#Get date >> 27 june 2011
#AS YYYYMMDD format >> 20110627
#if you really want to use awk
echo "27 june 2011" | awk '{print "date -d\""$1FS$2FS$3"\" +%Y%m%d"}' | bash
#note | bash just redirects awk's output to the shell to be executed
#FS is field separator, in this case you can use $0 to print the line
#But this is useful if you have more than one date on a line
note this only works on GNU date
I have read that:
Solaris version of date, which is unable to support
-d
can be resolve with replacing sunfreeware.com version of date
It sounds like you're trying to SELECT
a column that doesn't exist.
Perhaps you're trying to ORDER BY
a column that doesn't exist?
Any typos in your SQL statement?
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,
DATA_TYPE
FROM INFORMATION_SCHEMA.COLUMNS
Where
TABLE_NAME = ''
1st Reason could be the ending tag of your application's web.xml file which could not have been closed properly.
web.xml might be ending with <web-app>
, but must end with </web-app>
2nd Reason which worked in my case could be the lib folder of your tomcat must contain the supporting jar file of your database.

Probably the most elegant way of doing this is to do it in one step. See val()
.
$("#text").val(function(i, val) {
return val.replace('.', ':');
});
compared to:
var val = $("#text").val();
$("#text").val(val.replace('.', ':'));
From the docs:
.val( function(index, value) )
function(index, value)A function returning the value to set.
This method is typically used to set the values of form fields. For
<select multiple="multiple">
elements, multiple s can be selected by passing in an array.The
.val()
method allows us to set the value by passing in a function. As of jQuery 1.4, the function is passed two arguments, the current element's index and its current value:$('input:text.items').val(function(index, value) { return value + ' ' + this.className; });
This example appends the string " items" to the text inputs' values.
This requires jQuery 1.4+.
Ok, finally found the solution.
Probably due to lack of experience with ReactJS and web development...
var Task = React.createClass({
render: function() {
var percentage = this.props.children + '%';
....
<div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
...
I created the percentage variable outside in the render function.
I'm getting OpenJDK 8 from the official Debian repositories, rather than some random PPA or non-free Oracle binary. Here's how I did it:
sudo apt-get install debian-keyring debian-archive-keyring
Make /etc/apt/sources.list.d/debian-jessie-backports.list
:
deb http://httpredir.debian.org/debian/ jessie-backports main
Make /etc/apt/preferences.d/debian-jessie-backports
:
Package: *
Pin: release o=Debian,a=jessie-backports
Pin-Priority: -200
Then finally do the install:
sudo apt-get update
sudo apt-get -t jessie-backports install openjdk-8-jdk
NOLOCK
is equivalent to READ UNCOMMITTED
, however Microsoft says you should not use it for UPDATE
or DELETE
statements:
For UPDATE or DELETE statements: This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
http://msdn.microsoft.com/en-us/library/ms187373.aspx
This article applies to SQL Server 2005, so the support for NOLOCK
exists if you are using that version. In order to future-proof you code (assuming you've decided to use dirty reads) you could use this in your stored procedures:
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
> After all, the answers have to be somewhere, haven't they? :)
Umm, no.
As several replies noted, the question is under-specified in ways that invite questions in response, not answers. To take just one way:
And then which programs? Which machine? Which OS? Which data set?
You can do using two options:
Using NSURLConnection:

Check out James Padolsey's animateToSelector
Intro: This jQuery plugin will allow you to animate any element to styles specified in your stylesheet. All you have to do is pass a selector and the plugin will look for that selector in your StyleSheet and will then apply it as an animation.
You have to use the SelectMany
extension method or its equivalent syntax in pure LINQ.
(from model in list
where model.application == "applicationname"
from user in model.users
where user.surname == "surname"
select new { user, model }).ToList();
Look at SignalR Tests for the feature.
Test "SendToUser" takes automatically the user identity passed by using a regular owin authentication library.
The scenario is you have a user who has connected from multiple devices/browsers and you want to push a message to all his active connections.
char_seen = []
for char in string:
if char not in char_seen:
char_seen.append(char)
print(''.join(char_seen))
This will preserve the order in which alphabets are coming,
output will be
abcd
In my case for Bootstrap4:
<body class="d-flex flex-column min-vh-100">
<div class="wrapper flex-grow-1"></div>
<footer></footer>
</body>
You just need to add disabled
as option
attribute
<option disabled>select one option</option>
timestamp is always time in utc, but when you call datetime.datetime.fromtimestamp
it returns you time in your local timezone corresponding to this timestamp, so result depend of your locale.
>>> import time, datetime
>>> time.time()
1564494136.0434234
>>> datetime.datetime.now()
datetime.datetime(2019, 7, 30, 16, 42, 3, 899179)
>>> datetime.datetime.fromtimestamp(time.time())
datetime.datetime(2019, 7, 30, 16, 43, 12, 4610)
There exist nice library arrow
with different behaviour. In same case it returns you time object with UTC timezone.
>>> import arrow
>>> arrow.now()
<Arrow [2019-07-30T16:43:27.868760+03:00]>
>>> arrow.get(time.time())
<Arrow [2019-07-30T13:43:56.565342+00:00]>
It works exactly as you expect it to work. There's a bug https://github.com/facebook/react-native/issues/282 that prevents it from working correctly.
If you have node_modules (with react_native) in the same folder as the xcode project, you can edit node_modules/react-native/packager/packager.js and make this change: https://github.com/facebook/react-native/pull/286/files . It'll work magically :)
If your react_native is installed somewhere else and the patch doesn't work, comment on https://github.com/facebook/react-native/issues/282 to let them know about your setup.

Just put ojdbc6.jar
in class path, so that we can fix CallbaleStatement
exception:
oracle.jdbc.driver.T4CPreparedStatement.setBinaryStream(ILjava/io/InputStream;J)V)
in Oracle.
Take a look at Directory.GetFiles Method (String, String) (MSDN).
This method returns all the files as an array of filenames.
select date_format(str_to_date('31/12/2010', '%d/%m/%Y'), '%Y%m');
or
select date_format(str_to_date('12/31/2011', '%m/%d/%Y'), '%Y%m');
hard to tell from your example
Don't manually edit the .designer files in visual studio that usually leads to headaches. Instead either specify it in the properties section of your DataGridRow which should be contained within a DataGrid element. Or if you just want VS to do it for you find the double click event within the properties page->events (little lightning bolt icon) and double click the text area where you would enter a function name for that event.

This answer builds up from the above excellent ones.
In most applications, you won't be calling logging.exception(e) directly. Most likely you have defined a custom logger specific for your application or module like this:
# Set the name of the app or module
my_logger = logging.getLogger('NEM Sequencer')
# Set the log level
my_logger.setLevel(logging.INFO)
# Let's say we want to be fancy and log to a graylog2 log server
graylog_handler = graypy.GELFHandler('some_server_ip', 12201)
graylog_handler.setLevel(logging.INFO)
my_logger.addHandler(graylog_handler)
In this case, just use the logger to call the exception(e) like this:
try:
1/0
except ZeroDivisionError, e:
my_logger.exception(e)
Before JavaScript 1.5: ^[a-zA-Z_$][0-9a-zA-Z_$]*$
In English: It must start with a dollar sign, underscore or one of letters in the 26-character alphabet, upper or lower case. Subsequent characters (if any) can be one of any of those or a decimal digit.
JavaScript 1.5 and later * : ^[\p{L}\p{Nl}$_][\p{L}\p{Nl}$\p{Mn}\p{Mc}\p{Nd}\p{Pc}]*$
This is more difficult to express in English, but it is conceptually similar to the older syntax with the addition that the letters and digits can be from any language. After the first character, there are also allowed additional underscore-like characters (collectively called “connectors”) and additional character combining marks (“modifiers”). (Other currency symbols are not included in this extended set.)
JavaScript 1.5 and later also allows Unicode escape sequences, provided that the result is a character that would be allowed in the above regular expression.
Identifiers also must not be a current reserved word or one that is considered for future use.
There is no practical limit to the length of an identifier. (Browsers vary, but you’ll safely have 1000 characters and probably several more orders of magnitude than that.)
Links to the character categories:
*n.b. This Perl regex is intended to describe the syntax only — it won’t work in JavaScript, which doesn’t (yet) include support for Unicode Properties. (There are some third-party packages that claim to add such support.)
add a float property to the #main_content

The Groovy way to do this is
def list = []
list << new MyType(...)
which creates a list and uses the overloaded leftShift
operator to append an item
See the Groovy docs on Lists for lots of examples.
var wordCount =
from word in words
group word by word into g
select new { g.Key, Count = g.Count() };
This is taken from one of the examples in the linqpad
I used this code to show the dialog at the bottom of the screen:
Dialog dlg = <code to create custom dialog>;
Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();
wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);
This code also prevents android from dimming the background of the dialog, if you need it. You should be able to change the gravity parameter to move the dialog about
private void showPictureialog() {
final Dialog dialog = new Dialog(this,
android.R.style.Theme_Translucent_NoTitleBar);
// Setting dialogview
Window window = dialog.getWindow();
window.setGravity(Gravity.CENTER);
window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
dialog.setTitle(null);
dialog.setContentView(R.layout.selectpic_dialog);
dialog.setCancelable(true);
dialog.show();
}
you can customize you dialog based on gravity and layout parameters change gravity and layout parameter on the basis of your requirenment
Yes, there's in fact many reasons why you can access AWS Lambda like and HTTP Endpoint.
The architecture of AWS Lambda
It's a microservice. Running inside EC2 with Amazon Linux AMI (Version 3.14.26–24.46.amzn1.x86_64) and runs with Node.js. The memory can be beetwen 128mb and 1gb. When the data source triggers the event, the details are passed to a Lambda function as parameter's.
What happen?
AWS Lambda run's inside a container, and the code is directly uploaded to this container with packages or modules. For example, we NEVER can do SSH for the linux machine running your lambda function. The only things that we can monitor are the logs, with CloudWatchLogs and the exception that came from the runtime.
AWS take care of launch and terminate the containers for us, and just run the code. So, even that you use require('http'), it's not going to work, because the place where this code runs, wasn't made for this.
Just use this website: http://ticons.fokkezb.nl :)
It makes it easier for you, and generates the correct sizes directly
Another solution using recursion:
def subsets(nums: List[int]) -> List[List[int]]:
n = len(nums)
output = [[]]
for num in nums:
output += [curr + [num] for curr in output]
return output
Starting from empty subset in output list. At each step we take a new integer into consideration and generates new subsets from the existing ones.
package lecture3;

I'm unsure of the context on why this was needed, so this may not return enough information for you but this is what I was able to do:
if(typeof(ModelName).GetProperty("Name of Property") != null)
{
//whatevver you were wanting to do.
}
In my case I'm running through properties from a form submission and also have default values to use if the entry is left blank - so I needed to know if the there was a value to use - I prefixed all my default values in the model with Default so all I needed to do is check if there was a property that started with that.
Firstly, in histories_T, you are referencing table T_customer (should be T_customers) and secondly, you are missing the FOREIGN KEY clause that REFERENCES orders; which is not being created (or dropped) with the code you provided.
There may be additional errors as well, and I admit Oracle has never been very good at describing the cause of errors - "Mutating Tables" is a case in point.
Let me know if there additional problems you are missing.
Make sure the scp command is available on both sides - both on the client and on the server.
If this is Fedora or Red Hat Enterprise Linux and clones (CentOS), make sure this package is installed:
yum -y install openssh-clients
If you work with Debian or Ubuntu and clones, install this package:
apt-get install openssh-client
Again, you need to do this both on the server and the client, otherwise you can encounter "weird" error messages on your client: scp: command not found
or similar although you have it locally. This already confused thousands of people, I guess :)
var myEle = document.getElementById("myElement");
if(myEle){
var myEleValue= myEle.value;
}
the return of getElementById is null if an element is not actually present inside the dom, so your if statement will fail, because null is considered a false value
Nothing special. Just as same as common Java Class Instance.
But those class are Synthetic proxy classes
created by java.lang.reflect.Proxy#newProxyInstance
Introduced in 1.3
http://docs.oracle.com/javase/1.3/docs/relnotes/features.html#reflection
It is a part of Java. so each JVM should support it.
In short : they are created using JVM ASM tech ( defining javabyte code at runtime )
something using same tech:
java.lang.reflect.Proxy#newProxyInstance
getProxyClass0
to obtain a `Class
`
ProxyGenerator.generateProxyClass
which return a byte[]define class
to load the generated $Proxy
Class (the classname you have seen)each method is build with same bytecode like
invocation handler
's invoke()
invocation handler
's invoke()
the class(bytecode) represent in form of byte[]
How to draw a class

Each controller has it's own scope(s) so that's causing your issue.
Having two controllers that want access to the same data is a classic sign that you want a service. The angular team recommends thin controllers that are just glue between views and services. And specifically- "services should hold shared state across controllers".
Happily, there's a nice 15-minute video describing exactly this (controller communication via services): video
One of the original author's of Angular, Misko Hevery, discusses this recommendation (of using services in this situation) in his talk entitled Angular Best Practices (skip to 28:08 for this topic, although I very highly recommended watching the whole talk).
You can use events, but they are designed just for communication between two parties that want to be decoupled. In the above video, Misko notes how they can make your app more fragile. "Most of the time injecting services and doing direct communication is preferred and more robust". (Check out the above link starting at 53:37 to hear him talk about this)
A fixed point number has a specific number of bits (or digits) reserved for the integer part (the part to the left of the decimal point) and a specific number of bits reserved for the fractional part (the part to the right of the decimal point). No matter how large or small your number is, it will always use the same number of bits for each portion. For example, if your fixed point format was in decimal IIIII.FFFFF
then the largest number you could represent would be 99999.99999
and the smallest non-zero number would be 00000.00001
. Every bit of code that processes such numbers has to have built-in knowledge of where the decimal point is.
A floating point number does not reserve a specific number of bits for the integer part or the fractional part. Instead it reserves a certain number of bits for the number (called the mantissa or significand) and a certain number of bits to say where within that number the decimal place sits (called the exponent). So a floating point number that took up 10 digits with 2 digits reserved for the exponent might represent a largest value of 9.9999999e+50
and a smallest non-zero value of 0.0000001e-49
.

When content is in file.py
from branch2 that is no longer applies to branch1, it requires picking some changes and leaving others. For full control do an interactive merge using the --patch
switch:
$ git checkout --patch branch2 file.py
The interactive mode section in the man page for git-add(1)
explains the keys that are to be used:
y - stage this hunk
n - do not stage this hunk
q - quit; do not stage this hunk nor any of the remaining ones
a - stage this hunk and all later hunks in the file
d - do not stage this hunk nor any of the later hunks in the file
g - select a hunk to go to
/ - search for a hunk matching the given regex
j - leave this hunk undecided, see next undecided hunk
J - leave this hunk undecided, see next hunk
k - leave this hunk undecided, see previous undecided hunk
K - leave this hunk undecided, see previous hunk
s - split the current hunk into smaller hunks
e - manually edit the current hunk
? - print help
The split command is particularly useful.
There's no need to use a library for such a trivial task:
var divs = document.getElementsByTagName("div"); // order: first, second, third
divs[2].parentNode.insertBefore(divs[2], divs[0]); // order: third, first, second
divs[2].parentNode.insertBefore(divs[2], divs[1]); // order: third, second, first
This takes account of the fact that getElementsByTagName
returns a live NodeList that is automatically updated to reflect the order of the elements in the DOM as they are manipulated.
You could also use:
var divs = document.getElementsByTagName("div"); // order: first, second, third
divs[0].parentNode.appendChild(divs[0]); // order: second, third, first
divs[1].parentNode.insertBefore(divs[0], divs[1]); // order: third, second, first
and there are various other possible permutations, if you feel like experimenting:
divs[0].parentNode.appendChild(divs[0].parentNode.replaceChild(divs[2], divs[0]));
for example :-)

This works for me if you have config and the private key file in the /Jenkins/.ssh/ you need to chown (change owner) for these 2 files then restart jenkins in order for the jenkins instance to read these 2 files.
you can use :
$('#timePicker').datetimepicker({
format:'d.m.Y H:i',
minDate: ge_today_date(new Date())
});
function ge_today_date(date) {
var day = date.getDate();
var month = date.getMonth() + 1;
var year = date.getFullYear().toString().slice(2);
return day + '-' + month + '-' + year;
}
If you have access to SRV Records, you can use them to get what you want :)
E.G
A Records
Name: mc1.domain.com
Value: <yourIP>
Name: mc2.domain.com
Value: <yourIP>
SRV Records
Name: _minecraft._tcp.mc1.domain.com
Priority: 5
Weight: 5
Port: 25565
Value: mc1.domain.com
Name: _minecraft._tcp.mc2.domain.com
Priority: 5
Weight: 5
Port: 25566
Value: mc2.domain.com
then in minecraft you can use
mc1.domain.com which will sign you into server 1 using port 25565
and
mc2.domain.com which will sign you into server 2 using port 25566
then on your router you can have it point 25565 and 25566 to the machine with both servers on and Voilà!
Source: This works for me running 2 minecraft servers on the same machine with ports 50500 and 50501

Here is my PHP solution, 100% Task Score, 100% correctness, and 100% performance. First we iterate and we store all positive elements, then we check if they exist,
function solution($A) {
$B = [];
foreach($A as $a){
if($a > 0) $B[] = $a;
}
$i = 1;
$last = 0;
sort($B);
foreach($B as $b){
if($last == $b) $i--; // Check for repeated elements
else if($i != $b) return $i;
$i++;
$last = $b;
}
return $i;
}
I think its one of the clears and simples functions here, the logic can be applied in all the other languages.
git push origin amd_qlp_tester
will work for you. If you just type git push
, then the remote of the current branch is the default value.
Syntax of push looks like this - git push <remote> <branch>
. If you look at your remote in .git/config
file, you will see an entry [remote "origin"]
which specifies url of the repository. So, in the first part of command you will tell Git where to find repository for this project, and then you just specify a branch.
Here is another way of doing it with :)
git log | grep -o '\w\{8,\}' | head -n 1

Your variable size
is declared as: float size;
You can't use a floating point variable as the size of an array - it needs to be an integer value.
You could cast it to convert to an integer:
float *temp = new float[(int)size];
Your other problem is likely because you're writing outside of the bounds of the array:
float *temp = new float[size];
//Getting input from the user
for (int x = 1; x <= size; x++){
cout << "Enter temperature " << x << ": ";
// cin >> temp[x];
// This should be:
cin >> temp[x - 1];
}
Arrays are zero based in C++, so this is going to write beyond the end and never write the first element in your original code.
A "Login" grants the principal entry into the SERVER.
A "User" grants a login entry into a single DATABASE.
One "Login" can be associated with many users (one per database).
Each of the above objects can have permissions granted to it at its own level. See the following articles for an explanation of each
I just put this together. The incrementer in the wordCount() method is a bit inelegant to me, but it works.
import java.util.*;
public class WordCounter {
private String word;
private int numWords;
public int wordCount(String wrd) {
StringTokenizer token = new StringTokenizer(wrd, " ");
word = token.nextToken();
numWords = token.countTokens();
numWords++;
return numWords;
}
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String userWord;
WordCounter wc = new WordCounter();
System.out.println("Enter a sentence.");
userWord = input.nextLine();
wc.wordCount(userWord);
System.out.println("You sentence was " + wc.numWords + " words long.");
}

Short answer:
Going by the answer given here. You can have two applications listening on the same IP address, and port number, so long one of the port is a UDP port, while other is a TCP port.
Explanation:
The concept of port is relevant on the transport layer of the TCP/IP stack, thus as long as you are using different transport layer protocols of the stack, you can have multiple processes listening on the same <ip-address>:<port>
combination.
One doubt that people have is if two applications are running on the same <ip-address>:<port>
combination, how will a client running on a remote machine distinguish between the two? If you look at the IP layer packet header (https://en.wikipedia.org/wiki/IPv4#Header), you will see that bits 72 to 79 are used for defining protocol, this is how the distinction can be made.
If however you want to have two applications on same TCP <ip-address>:<port>
combination, then the answer is no (An interesting exercise will be launch two VMs, give them same IP address, but different MAC addresses, and see what happens - you will notice that some times VM1 will get packets, and other times VM2 will get packets - depending on ARP cache refresh).
I feel that by making two applications run on the same <op-address>:<port>
you want to achieve some kind of load balancing. For this you can run the applications on different ports, and write IP table rules to bifurcate the traffic between them.

One of the things to also keep in mind is that when you have Visual Studio 2010 SP1 installed some C++ compilers and libraries may have been removed. There's been an update made available by Microsoft to make sure those are brought back to your system.
Install this update to restore the Visual C++ compilers and libraries that may have been removed when Visual Studio 2010 Service Pack 1 (SP1) was installed. The compilers and libraries are part of the Microsoft Windows Software Development Kit for Windows 7 and the .NET Framework 4 (later referred to as the Windows SDK 7.1).
Also, when you read the VS2010 SP1 README you'll also notice that some notes have been made in regards to the Windows 7 SDK (See section 2.2.1) installation. It may be that one of these conditions may apply to you and therefore may need to uncheck the C++ compiler-checkbox as the SDK installer will attempt to install an older version of compilers ÓR you may need to uninstall VS2010 SP1 and re-run the SDK 7.1 installation, repair or modification.
Condition 1: If the Visual C++ Compilers checkbox is selected when the Windows SDK 7.1 is installed, repaired, or modified after Visual Studio 2010 SP1 has been installed, the error may be encountered and some selected components may not be installed.
Workaround: Clear the Visual C++ Compilers checkbox before you run the Windows SDK 7.1 installation, repair, or modification.
Condition 2: If the Visual C++ Compilers checkbox is selected when the Windows SDK 7.1 is installed, repaired, or modified after Visual Studio 2010 has been installed but Visual Studio 2010 SP1 has not been uninstalled, the error may be encountered.
Workaround: Uninstall Visual Studio 2010 SP1 and then rerun the Windows SDK 7.1 installation, repair, or modification.
However, even then I found that I still needed to uninstall any existing Visual C++ 2010 redistributables, as has been suggested by mgrandi.
This can't be done by using a Comparator

One hackish way to define an exit
method in context:
class Bar; def exit; end; end
This works because exit
in the initializer will be resolved as self.exit
1. In addition, this approach allows using the object after it has been created, as in: b = B.new
.
But really, one shouldn't be doing this: don't have exit
(or even puts
) there to begin with.
(And why is there an "infinite" loop and/or user input in an intiailizer? This entire problem is primarily the result of poorly structured code.)
1 Remember Kernel#exit is only a method. Since Kernel is included in every Object, then it's merely the case that exit
normally resolves to Object#exit
. However, this can be changed by introducing an overridden method as shown - nothing fancy.

Both examples in the question are actually very bad examples that can lead to data loss!
My advice: never append /*
to directories in .gitignore files, unless you have a good reason!
A good reason would be for example what Jefromi wrote: "if you intend to subsequently un-ignore something in the directory".
The reason why it otherwise shouldn't be done is that appending /*
to directories does on the one hand work in the manner that it properly ignores all contents of the directory, but on the other hand it has a dangerous side effect:
If you execute git stash -u
(to temporarily stash tracked and untracked files) or git clean -df
(to delete untracked but keep ignored files) in your repository, all directories that are ignored with an appended /*
will be irreversibly deleted!
I had to learn this the hard way. Somebody in my team was appending /*
to some directories in our .gitignore. Over the time I had occasions where certain directories would suddenly disappear. Directories with gigabytes of local data needed by our application. Nobody could explain it and I always hat to re-download all data. After a while I got a notion that it might have to do with git stash
. One day I wanted to clean my local repo (while keeping ignored files) and I was using git clean -df
and again my data was gone. This time I had enough and investigated the issue. I finally figured that the reason is the appended /*
.
I assume it can be explained somehow by the fact that directory/*
does ignore all contents of the directory but not the directory itself. Thus it's neither considered tracked nor ignored when things get deleted. Even though git status
and git status --ignored
give a slightly different picture on it.
Here is how to reproduce the behaviour. I'm currently using Git 2.8.4.
A directory called localdata/
with a dummy file in it (important.dat
) will be created in a local git repository and the contents will be ignored by putting /localdata/*
into the .gitignore
file. When one of the two mentioned git commands is executed now, the directory will be (unexpectedly) lost.
mkdir test
cd test
git init
echo "/localdata/*" >.gitignore
git add .gitignore
git commit -m "Add .gitignore."
mkdir localdata
echo "Important data" >localdata/important.dat
touch untracked-file
If you do a git status --ignored
here, you'll get:
On branch master
Untracked files:
(use "git add <file>..." to include in what will be committed)
untracked-file
Ignored files:
(use "git add -f <file>..." to include in what will be committed)
localdata/
Now either do
git stash -u
git stash pop
or
git clean -df
In both cases the allegedly ignored directory localdata
will be gone!
Not sure if this can be considered a bug, but I guess it's at least a feature that nobody needs.
I'll report that to the git development list and see what they think about it.
You can factor out your common logic to a private method, for example called Initialize
that gets called from both constructors.
Due to the fact that you want to perform argument validation you cannot resort to constructor chaining.
Example:
public Point2D(double x, double y)
{
// Contracts
Initialize(x, y);
}
public Point2D(Point2D point)
{
if (point == null)
throw new ArgumentNullException("point");
// Contracts
Initialize(point.X, point.Y);
}
private void Initialize(double x, double y)
{
X = x;
Y = y;
}

In WPF there are certain 'container' controls that automatically resize their contents and there are some that don't.
Here are some that do not resize their contents (I'm guessing that you are using one or more of these):
StackPanel
WrapPanel
Canvas
TabControl
Here are some that do resize their contents:
Grid
UniformGrid
DockPanel
Therefore, it is almost always preferable to use a Grid
instead of a StackPanel
unless you do not want automatic resizing to occur. Please note that it is still possible for a Grid
to not size its inner controls... it all depends on your Grid.RowDefinition
and Grid.ColumnDefinition
settings:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="100" /> <!--<<< Exact Height... won't resize -->
<RowDefinition Height="Auto" /> <!--<<< Will resize to the size of contents -->
<RowDefinition Height="*" /> <!--<<< Will resize taking all remaining space -->
</Grid.RowDefinitions>
</Grid>
You can find out more about the Grid
control from the Grid
Class page on MSDN. You can also find out more about these container controls from the WPF Container Controls Overview page on MSDN.
Further resizing can be achieved using the FrameworkElement.HorizontalAlignment
and FrameworkElement.VerticalAlignment
properties. The default value of these properties is Stretch
which will stretch elements to fit the size of their containing controls. However, when they are set to any other value, the elements will not stretch.
UPDATE >>>
In response to the questions in your comment:
Use the Grid.RowDefinition
and Grid.ColumnDefinition
settings to organise a basic structure first... it is common to add Grid
controls into the cells of outer Grid
controls if need be. You can also use the Grid.ColumnSpan
and Grid.RowSpan
properties to enable controls to span multiple columns and/or rows of a Grid
.
It is most common to have at least one row/column with a Height
/Width
of "*"
which will fill all remaining space, but you can have two or more with this setting, in which case the remaining space will be split between the two (or more) rows/columns. 'Auto' is a good setting to use for the rows/columns that are not set to '"*"', but it really depends on how you want the layout to be.
There is no Auto
setting that you can use on the controls in the cells, but this is just as well, because we want the Grid
to size the controls for us... therefore, we don't want to set the Height
or Width
of these controls at all.
The point that I made about the FrameworkElement.HorizontalAlignment
and FrameworkElement.VerticalAlignment
properties was just to let you know of their existence... as their default value is already Stretch
, you don't generally need to set them explicitly.
The Margin
property is generally just used to space your controls out evenly... if you drag and drop controls from the Visual Studio Toolbox, VS will set the Margin
property to place your control exactly where you dropped it but generally, this is not what we want as it will mess with the auto sizing of controls. If you do this, then just delete or edit the Margin
property to suit your needs.
As of SQL Server 2016 you have
DROP TABLE IF EXISTS [foo];
Does it support
<!DOCTYPE html>
Yes it does.
Perhaps a better question is what modern web features IE8 supports. Some of the best places to answer that are caniuse.com, html5test.com, and browserscope.org.
HTML5 means a lot of different things to different people. These days, it means HTML, CSS, and JavaScript functionality. The term is becoming a bit "Web 2.0"-like.
We can use the angular.element(document).ready()
method to attach callbacks for when the document is ready. We can simply attach the callback in the controller like so:
angular.module('MyApp', [])
.controller('MyCtrl', [function() {
angular.element(document).ready(function () {
document.getElementById('msg').innerHTML = 'Hello';
});
}]);
If you prefer using method (lambda) syntax as I do, you could do the same thing like this:
var result = new TableName();
using(var db = new EFObjectContext)
{
var query = db.TableName;
query = value1 == null
? query.Where(tbl => tbl.entry1 == null)
: query.Where(tbl => tbl.entry1 == value1);
query = value2 == null
? query.Where(tbl => tbl.entry2 == null)
: query.Where(tbl => tbl.entry2 == value2);
result = query
.Select(tbl => tbl)
.FirstOrDefault();
// Inspect the value of the trace variable below to see the sql generated by EF
var trace = ((ObjectQuery<REF_EQUIPMENT>) query).ToTraceString();
}
return result;
If you know how many rows there will be in total you can use the ROW_NUMBER() function. Here's an examble from MSDN (http://msdn.microsoft.com/en-us/library/ms186734.aspx)
USE AdventureWorks;
GO
WITH OrderedOrders AS
(
SELECT SalesOrderID, OrderDate,
ROW_NUMBER() OVER (ORDER BY OrderDate) AS 'RowNumber'
FROM Sales.SalesOrderHeader
)
SELECT *
FROM OrderedOrders
WHERE RowNumber BETWEEN 50 AND 60;
.remove()
is deprecated. instead we can use deleteMany
DateTime.deleteMany({}, callback)
.
An answer that doesn't rely on numpy, either:
import math
from collections import Counter
def eta(data, unit='natural'):
base = {
'shannon' : 2.,
'natural' : math.exp(1),
'hartley' : 10.
}
if len(data) <= 1:
return 0
counts = Counter()
for d in data:
counts[d] += 1
ent = 0
probs = [float(c) / len(data) for c in counts.values()]
for p in probs:
if p > 0.:
ent -= p * math.log(p, base[unit])
return ent
This will accept any datatype you could throw at it:
>>> eta(['mary', 'had', 'a', 'little', 'lamb'])
1.6094379124341005
>>> eta([c for c in "mary had a little lamb"])
2.311097886212714
The answer provided by @Jarad suggested timings as well. To that end:
repeat_number = 1000000
e = timeit.repeat(
stmt='''eta(labels)''',
setup='''labels=[1,3,5,2,3,5,3,2,1,3,4,5];from __main__ import eta''',
repeat=3,
number=repeat_number)
Timeit results: (I believe this is ~4x faster than the best numpy approach)
print('Method: {}, Avg.: {:.6f}'.format("eta", np.array(e).mean()))
Method: eta, Avg.: 10.461799

Okay, just to clarify things that have already been posted.
You should have the directory com
, containing the directory company
, containing the directory example
, containing the file MyClass.java
.
From the folder containing com
, run:
$ javac com\company\example\MyClass.java
Then:
$ java com.company.example.MyClass Hello from MyClass!
These must both be done from the root of the source tree. Otherwise, javac
and java
won't be able to find any other packages (in fact, java
wouldn't even be able to run MyClass
).
I created the folders "testpackage" and "testpackage2". Inside testpackage, I created TestPackageClass.java containing the following code:
package testpackage;
import testpackage2.MyClass;
public class TestPackageClass {
public static void main(String[] args) {
System.out.println("Hello from testpackage.TestPackageClass!");
System.out.println("Now accessing " + MyClass.NAME);
}
}
Inside testpackage2, I created MyClass.java containing the following code:
package testpackage2;
public class MyClass {
public static String NAME = "testpackage2.MyClass";
}
From the directory containing the two new folders, I ran:
C:\examples>javac testpackage\*.java C:\examples>javac testpackage2\*.java
Then:
C:\examples>java testpackage.TestPackageClass Hello from testpackage.TestPackageClass! Now accessing testpackage2.MyClass

The primary goal of a hashmap is to store a data set and provide near constant time lookups on it using a unique key. There are two common styles of hashmap implementation:
Separate chaining is preferable if the hashmap may have a poor hash function, it is not desirable to pre-allocate storage for potentially unused slots, or entries may have variable size. This type of hashmap may continue to function relatively efficiently even when the load factor exceeds 1.0. Obviously, there is extra memory required in each entry to store linked list pointers.
Hashmaps using open addressing have potential performance advantages when the load factor is kept below a certain threshold (generally about 0.7) and a reasonably good hash function is used. This is because they avoid potential cache misses and many small memory allocations associated with a linked list, and perform all operations in a contiguous, pre-allocated array. Iteration through all elements is also cheaper. The catch is hashmaps using open addressing must be reallocated to a larger size and rehashed to maintain an ideal load factor, or they face a significant performance penalty. It is impossible for their load factor to exceed 1.0.
Some key performance metrics to evaluate when creating a hashmap would include:
Here is a flexible hashmap implementation I made. I used open addressing and linear probing for collision resolution.

background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}
I'd suggest not going for a direct conversion. Convert XML to an object, then from the object to JSON.
In my opinion, this gives a cleaner definition of how the XML and JSON correspond.
It takes time to get right and you may even write tools to help you with generating some of it, but it would look roughly like this:
class Channel:
def __init__(self)
self.items = []
self.title = ""
def from_xml( self, xml_node ):
self.title = xml_node.xpath("title/text()")[0]
for x in xml_node.xpath("item"):
item = Item()
item.from_xml( x )
self.items.append( item )
def to_json( self ):
retval = {}
retval['title'] = title
retval['items'] = []
for x in items:
retval.append( x.to_json() )
return retval
class Item:
def __init__(self):
...
def from_xml( self, xml_node ):
...
def to_json( self ):
...
Use profiler module. It gives a very detailed profile.
import profile
profile.run('main()')
it outputs something like:

I've found it very informative.
To turn off foreign key constraint globally, do the following:
SET GLOBAL FOREIGN_KEY_CHECKS=0;
and remember to set it back when you are done
SET GLOBAL FOREIGN_KEY_CHECKS=1;

SELECT name
FROM orders,company
WHERE orderID = 1
AND companyID IN (attachedCompanyIDs)
attachedCompanyIDs
is a scalar value which is cast into INT
(type of companyID
).
The cast only returns numbers up to the first non-digit (a comma in your case).
Thus,
companyID IN ('1,2,3') = companyID IN (CAST('1,2,3' AS INT)) = companyID IN (1)
In PostgreSQL
, you could cast the string into array (or store it as an array in the first place):
SELECT name
FROM orders
JOIN company
ON companyID = ANY (('{' | attachedCompanyIDs | '}')::INT[])
WHERE orderID = 1
and this would even use an index on companyID
.
Unfortunately, this does not work in MySQL
since the latter does not support arrays.
You may find this article interesting (see #2
):
Update:
If there is some reasonable limit on the number of values in the comma separated lists (say, no more than 5
), so you can try to use this query:
SELECT name
FROM orders
CROSS JOIN
(
SELECT 1 AS pos
UNION ALL
SELECT 2 AS pos
UNION ALL
SELECT 3 AS pos
UNION ALL
SELECT 4 AS pos
UNION ALL
SELECT 5 AS pos
) q
JOIN company
ON companyID = CAST(NULLIF(SUBSTRING_INDEX(attachedCompanyIDs, ',', -pos), SUBSTRING_INDEX(attachedCompanyIDs, ',', 1 - pos)) AS UNSIGNED)
SELECT @i:=@i+1 AS iterator, t.*
FROM tablename t,(SELECT @i:=0) foo
function stringToUint(string) {
var string = btoa(unescape(encodeURIComponent(string))),
charList = string.split(''),
uintArray = [];
for (var i = 0; i < charList.length; i++) {
uintArray.push(charList[i].charCodeAt(0));
}
return new Uint8Array(uintArray);
}
function uintToString(uintArray) {
var encodedString = String.fromCharCode.apply(null, uintArray),
decodedString = decodeURIComponent(escape(atob(encodedString)));
return decodedString;
}
I have done, with some help from the internet, these little functions, they should solve your problems! Here is the working JSFiddle.
EDIT:
Since the source of the Uint8Array is external and you can't use atob
you just need to remove it(working fiddle):
function uintToString(uintArray) {
var encodedString = String.fromCharCode.apply(null, uintArray),
decodedString = decodeURIComponent(escape(encodedString));
return decodedString;
}
Warning: escape and unescape is removed from web standards. See this.

ctlAllPostbackData.Text = "<div class='well well-lg' style='border:1px solid black;z-index:99999;position:absolute;'><h3>All postback data:</h3><br />";
for (int i = 0; i < keys.Length; i++)
{
ctlAllPostbackData.Text += "<b>" + keys[i] + "</b>: " + Request[keys[i]] + "<br />";
}
ctlAllPostbackData.Text += "</div>";
this.Controls.Add(ctlAllPostbackData);
}
}
Adding to @CR Rollyson answer,
In case if you have a collapsible div which has a min-height attribute, it will also cause the jerking. Try removing that attribute from directly collapsible div. Use it in the child div of the collapsible div.
<div class="form-group">
<a for="collapseOne" data-toggle="collapse" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne">+ Not Jerky</a>
<div class="collapse" id="collapseOne" style="padding: 0;">
<textarea class="form-control" rows="4" style="padding: 20px;">No padding on animated element. Padding on child.</textarea>
</div>
</div>
Here is a good starting point.
HTML:
<div class="containing-table">
<div class="centre-align">
<div class="content"></div>
</div>
</div>
CSS:
.containing-table {
display: table;
width: 100%;
height: 400px; /* for demo only */
border: 1px dotted blue;
}
.centre-align {
padding: 10px;
border: 1px dashed gray;
display: table-cell;
text-align: center;
vertical-align: middle;
}
.content {
width: 50px;
height: 50px;
background-color: red;
display: inline-block;
vertical-align: top; /* Removes the extra white space below the baseline */
}
See demo at: http://jsfiddle.net/audetwebdesign/jSVyY/
.containing-table
establishes the width and height context for .centre-align
(the table-cell).
You can apply text-align
and vertical-align
to alter .centre-align
as needed.
Note that .content
needs to use display: inline-block
if it is to be centered horizontally using the text-align property.
There's a new package called installr that can update your R version within R on the Windows platform. The package was built under version 3.2.3
From R Studio, click on Tools and select Install Packages... then type the name "installr" and click install. Alternatively, you may type install.packages("installr") in the Console.
Once R studio is done installing the package, load it by typing require(installr) in the Console.
To start the updating process for your R installation, type updateR(). This function will check for newer versions of R and if available, it will guide you through the decisions you need to make. If your R installation is up-to-date, it will return FALSE.
If you choose to download and install a newer version. There's an option for copying/moving all of your packages from the current R installation to the newer R installation which is very handy.
Quit and restart R Studio once the update process is over. R Studio will load the newer R version.
Follow this link if you wish to learn more on how to use the installr package.
EDIT: I realized a little late that it was bound to a DataTable. In that case the idea is the same, and you can cast to a DataRowView
then take its Row
property to get a DataRow
if you want to work with that class.
foreach (var item in checkedListBox1.CheckedItems)
{
var row = (item as DataRowView).Row;
MessageBox.Show(row["ID"] + ": " + row["CompanyName"]);
}
You would need to cast or parse the items to their strongly typed equivalents, or use the System.Data.DataSetExtensions
namespace to use the DataRowExtensions.Field
method demonstrated below:
foreach (var item in checkedListBox1.CheckedItems)
{
var row = (item as DataRowView).Row;
int id = row.Field<int>("ID");
string name = row.Field<string>("CompanyName");
MessageBox.Show(id + ": " + name);
}
You need to cast the item to access the properties of your class.
foreach (var item in checkedListBox1.CheckedItems)
{
var company = (Company)item;
MessageBox.Show(company.Id + ": " + company.CompanyName);
}
Alternately, you could use the OfType
extension method to get strongly typed results back without explicitly casting within the loop:
foreach (var item in checkedListBox1.CheckedItems.OfType<Company>())
{
MessageBox.Show(item.Id + ": " + item.CompanyName);
}
The correct parameter to set the maximum length is:
SET @@group_concat_max_len = value_numeric;
value_numeric
must be > 1024; by default the group_concat_max_len
value is 1024.
Always keep in mind when you want to overcome this error, the default value of indexing and range starts from 0, so if total items is 100 then l[99] and range(99) will give you access up to the last element.
whenever you get this type of error please cross check with items that comes between/middle in range, and insure that their index is not last if you get output then you have made perfect error that mentioned above.
You can try this:
char tab[7]={'a','b','t','u','a','y','t'};
printf("%d\n",sizeof(tab)/sizeof(tab[0]));
In C, the order that you define things often matters. Either move the definition of outchar to the top, or provide a prototype at the top, like this:
#include <stdio.h> #include <stdlib.h> void outchar(char ch); int main() { outchar('A'); outchar('B'); outchar('C'); return 0; } void outchar(char ch) { printf("%c", ch); }
Also, you should be specifying the return type of every function. I added that for you.
This works setInterval("foo(bar)",int,lang);
.... Jon Kleiser lead me to the answer.
I just closed all open chrome instances, stopped my project and then start it again. that fixed the problem for me.
I'm going to show you an example that will help you to understand why it's important.
Such as you have some Box Widgets and you want to show some hidden content inside every single widget. You can do this easily when you have a different CSS class for the single widget but when it has the same class how can you do that?

I assume you are using windows. Open the command prompt and type ipconfig
and find out your local address (on your pc) it should look something like 192.168.1.13
or 192.168.0.5
where the end digit is the one that changes. It should be next to IPv4 Address.
If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13
If you have a virtual host then you will need root to edit the hosts file.
If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.
See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.
Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).
If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow
to allow,deny
in the httpd.conf
file. You can access this by the WAMP menu.
To eliminate possible causes of the issue for now set your config file to
<Directory />
Options FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
<RequireAll>
Require all granted
</RequireAll>
</Directory>
As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.
Config file that fixed the problem:
https://gist.github.com/samvaughton/6790739
Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.
If the container has already exited (maybe due to some error), you can do
$ docker run --rm -it --entrypoint /bin/ash image_name
or
$ docker run --rm -it --entrypoint /bin/sh image_name
or
$ docker run --rm -it --entrypoint /bin/bash image_name
to create a new container and get a shell into it. Since you specified --rm, the container would be deleted when you exit the shell.
I know it's an old question, but I share the best solution I found to solve this common problem
btnSomeButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// Prevent Two Click
Utils.preventTwoClick(view);
// Do magic
}
});
And in another file,like Utils.java
/**
* Método para prevenir doble click en un elemento
* @param view
*/
public static void preventTwoClick(final View view){
view.setEnabled(false);
view.postDelayed(new Runnable() {
public void run() {
view.setEnabled(true);
}
}, 500);
}
The message seems to be out of date. In version 4 that setting exists in two files, and you need to change it in the other one, which is:
%APPDATA%\sqldeveloper\1.0.0.0.0\product.conf
Which you might need to expand to your actual APPDATA
, which will be something like C:\Users\cprasad\AppData\Roaming
. In that file you will see the SetJavaHome
is currently going to be set to the path to your Java 1.8 location, so change that as you did in the sqldeveloper.conf
:
SetJavaHome C:\Program Files\Java\jdk1.7.0_60\bin\
If the settig is blank (in both files, I think) then it should prompt you to pick the JDK location when you launch it, if you prefer.

It's fairly easy to do. Create a UILabel
sublcass with a verticalAlignment
property and override textRectForBounds:limitedToNumberOfLines
to return the correct bounds for a top, middle or bottom vertical alignment. Here's the code:
SOLabel.h
#import <UIKit/UIKit.h>
typedef enum
{
VerticalAlignmentTop = 0, // default
VerticalAlignmentMiddle,
VerticalAlignmentBottom,
} VerticalAlignment;
@interface SOLabel : UILabel
@property (nonatomic, readwrite) VerticalAlignment verticalAlignment;
@end
SOLabel.m
@implementation SOLabel
-(id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (!self) return nil;
// set inital value via IVAR so the setter isn't called
_verticalAlignment = VerticalAlignmentTop;
return self;
}
-(VerticalAlignment) verticalAlignment
{
return _verticalAlignment;
}
-(void) setVerticalAlignment:(VerticalAlignment)value
{
_verticalAlignment = value;
[self setNeedsDisplay];
}
// align text block according to vertical alignment settings
-(CGRect)textRectForBounds:(CGRect)bounds
limitedToNumberOfLines:(NSInteger)numberOfLines
{
CGRect rect = [super textRectForBounds:bounds
limitedToNumberOfLines:numberOfLines];
CGRect result;
switch (_verticalAlignment)
{
case VerticalAlignmentTop:
result = CGRectMake(bounds.origin.x, bounds.origin.y,
rect.size.width, rect.size.height);
break;
case VerticalAlignmentMiddle:
result = CGRectMake(bounds.origin.x,
bounds.origin.y + (bounds.size.height - rect.size.height) / 2,
rect.size.width, rect.size.height);
break;
case VerticalAlignmentBottom:
result = CGRectMake(bounds.origin.x,
bounds.origin.y + (bounds.size.height - rect.size.height),
rect.size.width, rect.size.height);
break;
default:
result = bounds;
break;
}
return result;
}

I had good experience with SUDS https://fedorahosted.org/suds
Used their TestSuite as documentation.
Others have pointed out the error in your existing code, but I'd like to take two steps further. Firstly, assuming you're using Java 1.5+, you can achieve greater readability using the enhanced for loop:
Customer findCustomerByid(int id){
for (Customer customer : customers) {
if (customer.getId() == id) {
return customer;
}
}
return null;
}
This has also removed the micro-optimisation of returning null
before looping - I doubt that you'll get any benefit from it, and it's more code. Likewise I've removed the exists
flag: returning as soon as you know the answer makes the code simpler.
Note that in your original code I think you had a bug. Having found that the customer at index i
had the right ID, you then returned the customer at index id
- I doubt that this is really what you intended.
Secondly, if you're going to do a lot of lookups by ID, have you considered putting your customers into a Map<Integer, Customer>
?
You can use:
adb shell monkey -p com.package.name -c android.intent.category.LAUNCHER 1
This will start the LAUNCHER Activity of the application using monkeyrunner test tool.
I would strongly recommend that you bundle the DateJS library with your plugin and document the fact that you've done it. Nothing is more frustrating than having to hunt down dependencies.
That said, for legal reasons, you may not always be able to bundle everything. It also never hurts to be cautious and check for the existence of the plugin using Eran Galperin's answer.
PNG has 2 advantages: it has smaller size and it's more widely used and supported (except in case favicons). As mentioned before ICO, can have multiple size icons, which is useful for desktop applications, but not too much for websites. I would recommend you to put a favicon.ico in the root of your application. An if you have access to the Head of your website pages use the tag to point to a png file. So older browser will show the favicon.ico and newer ones the png.
To create Png and Icon files I would recommend The Gimp.
Like this.
function printMousePos(event) {_x000D_
document.body.textContent =_x000D_
"clientX: " + event.clientX +_x000D_
" - clientY: " + event.clientY;_x000D_
}_x000D_
_x000D_
document.addEventListener("click", printMousePos);
_x000D_
MouseEvent.clientX Read only
The X coordinate of the mouse pointer in local (DOM content) coordinates.MouseEvent.clientY Read only
The Y coordinate of the mouse pointer in local (DOM content) coordinates.
grep
For non-greedy match in grep
you could use a negated character class. In other words, try to avoid wildcards.
For example, to fetch all links to jpeg files from the page content, you'd use:
grep -o '"[^" ]\+.jpg"'
To deal with multiple line, pipe the input through xargs
first. For performance, use ripgrep
.
EDIT (2019) This answer is now pretty redundant but there is another answer with more relevant information.
It rather depends on the web server and web browser:
Internet explorer All versions 2GB-1
Mozilla Firefox All versions 2GB-1
IIS 1-5 2GB-1
IIS 6 4GB-1
Although IIS only support 200KB by default, the metabase needs amending to increase this.

The POST method itself does not have any limit on the size of data.
The problem of using Application.Restart() is, that it starts a new process but the "old" one is still remaining. Therefor I decided to Kill the old process by using the following code snippet:
if(Condition){
Application.Restart();
Process.GetCurrentProcess().Kill();
}
And it works proper good. In my case MATLAB and a C# Application are sharing the same SQLite database. If MATLAB is using the database, the Form-App should restart (+Countdown) again, until MATLAB reset its busy bit in the database. (Just for side information)
Learn more about how to navigate through the parse tree in BeautifulSoup
. Parse tree has got tags
and NavigableStrings
(as THIS IS A TEXT). An example
from BeautifulSoup import BeautifulSoup
doc = ['<html><head><title>Page title</title></head>',
'<body><p id="firstpara" align="center">This is paragraph <b>one</b>.',
'<p id="secondpara" align="blah">This is paragraph <b>two</b>.',
'</html>']
soup = BeautifulSoup(''.join(doc))
print soup.prettify()
# <html>
# <head>
# <title>
# Page title
# </title>
# </head>
# <body>
# <p id="firstpara" align="center">
# This is paragraph
# <b>
# one
# </b>
# .
# </p>
# <p id="secondpara" align="blah">
# This is paragraph
# <b>
# two
# </b>
# .
# </p>
# </body>
# </html>
To move down the parse tree you have contents
and string
.
contents is an ordered list of the Tag and NavigableString objects contained within a page element
if a tag has only one child node, and that child node is a string, the child node is made available as tag.string, as well as tag.contents[0]
For the above, that is to say you can get
soup.b.string
# u'one'
soup.b.contents[0]
# u'one'
For several children nodes, you can have for instance
pTag = soup.p
pTag.contents
# [u'This is paragraph ', <b>one</b>, u'.']
so here you may play with contents
and get contents at the index you want.
You also can iterate over a Tag, this is a shortcut. For instance,
for i in soup.body:
print i
# <p id="firstpara" align="center">This is paragraph <b>one</b>.</p>
# <p id="secondpara" align="blah">This is paragraph <b>two</b>.</p>
The simple way to fill the shape with the Radius is:
(view.getBackground()).setColorFilter(Color.parseColor("#FFDE03"), PorterDuff.Mode.SRC_IN);
I have dealt WCF with large file (serveral GB) upload where store data in memory is not an option. My solution is to store message stream to a temp file and use seek to find out begin and end of binary data.
I had trouble with this using matplotlib version: 2.0.2. Running the example from above I got a centered stacked set of bubbles.
I "fixed" the problem by adding another line:
plt.plot([],[])
The entire code snippet becomes:
import datetime
import random
import matplotlib.pyplot as plt
import matplotlib.dates as mdates
# make up some data
x = [datetime.datetime.now() + datetime.timedelta(minutes=i) for i in range(12)]
y = [i+random.gauss(0,1) for i,_ in enumerate(x)]
# plot
plt.plot([],[])
plt.scatter(x,y)
# beautify the x-labels
plt.gcf().autofmt_xdate()
myFmt = mdates.DateFormatter('%H:%M')
plt.gca().xaxis.set_major_formatter(myFmt)
plt.show()
plt.close()
This produces an image with the bubbles distributed as desired.
For the problem you're having about the batch file asking the user if the destination is a folder or file, if you know the answer in advance, you can do as such:
If destination is a file: echo f | [batch file path]
If folder: echo d | [batch file path]
It will essentially just pipe the letter after "echo" to the input of the batch file.
Watch this video, I had the same question. He shows you how to debug the service as well.
Here are his instructions using the basic C# Windows Service template in Visual Studio 2010/2012.
You add this to the Service1.cs file:
public void onDebug()
{
OnStart(null);
}
You change your Main() to call your service this way if you are in the DEBUG Active Solution Configuration.
static void Main()
{
#if DEBUG
//While debugging this section is used.
Service1 myService = new Service1();
myService.onDebug();
System.Threading.Thread.Sleep(System.Threading.Timeout.Infinite);
#else
//In Release this section is used. This is the "normal" way.
ServiceBase[] ServicesToRun;
ServicesToRun = new ServiceBase[]
{
new Service1()
};
ServiceBase.Run(ServicesToRun);
#endif
}
Keep in mind that while this is an awesome way to debug your service. It doesn't call OnStop()
unless you explicitly call it similar to the way we called OnStart(null)
in the onDebug()
function.
Is there a way to increase this size of memory an application can use?
Applications running on API Level 11+ can have android:largeHeap="true"
on the <application>
element in the manifest to request a larger-than-normal heap size, and getLargeMemoryClass()
on ActivityManager
will tell you how big that heap is. However:
This only works on API Level 11+ (i.e., Honeycomb and beyond)
There is no guarantee how large the large heap will be
The user will perceive your large-heap request, because it will force their other apps out of RAM terminate other apps' processes to free up system RAM for use by your large heap
Because of #3, and the fact that I expect that android:largeHeap
will be abused, support for this may be abandoned in the future, or the user may be warned about this at install time (e.g., you will need to request a special permission for it)
Presently, this feature is lightly documented
I'm taking some guesses here, because I don't quite understand what you're asking.
I think that what you want is a count of the number of lines on which the pattern 'echo' appears in the given file.
I've pasted your sample text into a file called 6741967
.
First, grep
finds the matches:
james@Brindle:tmp$grep echo 6741967
echo "Preparing to add a new user..."
echo "1. Add user"
echo "2. Exit"
echo "Enter your choice: "
Second, use wc -l
to count the lines
james@Brindle:tmp$grep echo 6741967 | wc -l
4
UPDATE user_account student
SET (student.student_education_facility_id) = (
SELECT teacher.education_facility_id
FROM user_account teacher
WHERE teacher.user_account_id = student.teacher_id AND teacher.user_type = 'ROLE_TEACHER'
)
WHERE student.user_type = 'ROLE_STUDENT';
If you set LD_PRELOAD
to the path of a shared object, that file will be loaded before any other library (including the C runtime, libc.so
). So to run ls
with your special malloc()
implementation, do this:
$ LD_PRELOAD=/path/to/my/malloc.so /bin/ls
Typically you model the enum itself as a class with the enum
stereotype
I had the same, eclipse polluted files even with one line change. Solution: Eclipse git settings -> Add Entry: Key: core.autocrlf Values: true
#
is an id selector, used to target a single specific element with a unique id, but . is a class selector used to target multiple elements with a particular class. To put it another way:
#foo {}
will style the single element declared with an attribute id="foo"
.foo {}
will style all elements with an attribute class="foo"
(you can have multiple classes assigned to an element too, just separate them with spaces, e.g. class="foo bar"
)Generally speaking, you use # for styling something you know is only going to appear once, for example, things like high level layout divs such sidebars, banner areas etc.
Classes are used where the style is repeated, e.g. say you head a special form of header for error messages, you could create a style h1.error {}
which would only apply to <h1 class="error">
Another aspect where selectors differ is in their specificity - an id selector is deemed to be more specific than class selector. This means that where styles conflict on an element, the ones defined with the more specific selector will override less specific selectors. For example, given <div id="sidebar" class="box">
any rules for #sidebar
with override conflicting rules for .box
See Selectutorial for more great primers on CSS selectors - they are incredibly powerful, and if your conception is simply that "# is used for DIVs" you'd do well to read up on exactly how to use CSS more effectively.
EDIT: Looks like Selectutorial might have gone to the big website in the sky, so try this archive link instead.
Function expressions in the JSON are completely possible, just do not forget to wrap it in double quotes. Here is an example taken from noSQL database design:
{_x000D_
"_id": "_design/testdb",_x000D_
"views": {_x000D_
"byName": {_x000D_
"map": "function(doc){if(doc.name){emit(doc.name,doc.code)}}"_x000D_
}_x000D_

Suppose you simply don't know the size of the data.frame in advance. It can well be a few rows, or a few millions. You need to have some sort of container, that grows dynamically. Taking in consideration my experience and all related answers in SO I come with 4 distinct solutions:
rbindlist
to the data.frame
Use data.table
's fast set
operation and couple it with manually doubling the table when needed.
Use RSQLite
and append to the table held in memory.
data.frame
's own ability to grow and use custom environment (which has reference semantics) to store the data.frame so it will not be copied on return.
Here is a test of all the methods for both small and large number of appended rows. Each method has 3 functions associated with it:
create(first_element)
that returns the appropriate backing object with first_element
put in.
append(object, element)
that appends the element
to the end of the table (represented by object
).
access(object)
gets the data.frame
with all the inserted elements.
rbindlist
to the data.frameThat is quite easy and straight-forward:
create.1<-function(elems)
{
return(as.data.table(elems))
}
append.1<-function(dt, elems)
{
return(rbindlist(list(dt, elems),use.names = TRUE))
}
access.1<-function(dt)
{
return(dt)
}
data.table::set
+ manually doubling the table when needed.I will store the true length of the table in a rowcount
attribute.
create.2<-function(elems)
{
return(as.data.table(elems))
}
append.2<-function(dt, elems)
{
n<-attr(dt, 'rowcount')
if (is.null(n))
n<-nrow(dt)
if (n==nrow(dt))
{
tmp<-elems[1]
tmp[[1]]<-rep(NA,n)
dt<-rbindlist(list(dt, tmp), fill=TRUE, use.names=TRUE)
setattr(dt,'rowcount', n)
}
pos<-as.integer(match(names(elems), colnames(dt)))
for (j in seq_along(pos))
{
set(dt, i=as.integer(n+1), pos[[j]], elems[[j]])
}
setattr(dt,'rowcount',n+1)
return(dt)
}
access.2<-function(elems)
{
n<-attr(elems, 'rowcount')
return(as.data.table(elems[1:n,]))
}
RSQLite
solutionThis is basically copy&paste of Karsten W. answer on similar thread.
create.3<-function(elems)
{
con <- RSQLite::dbConnect(RSQLite::SQLite(), ":memory:")
RSQLite::dbWriteTable(con, 't', as.data.frame(elems))
return(con)
}
append.3<-function(con, elems)
{
RSQLite::dbWriteTable(con, 't', as.data.frame(elems), append=TRUE)
return(con)
}
access.3<-function(con)
{
return(RSQLite::dbReadTable(con, "t", row.names=NULL))
}
data.frame
's own row-appending + custom environment.create.4<-function(elems)
{
env<-new.env()
env$dt<-as.data.frame(elems)
return(env)
}
append.4<-function(env, elems)
{
env$dt[nrow(env$dt)+1,]<-elems
return(env)
}
access.4<-function(env)
{
return(env$dt)
}
For convenience I will use one test function to cover them all with indirect calling. (I checked: using do.call
instead of calling the functions directly doesn't makes the code run measurable longer).
test<-function(id, n=1000)
{
n<-n-1
el<-list(a=1,b=2,c=3,d=4)
o<-do.call(paste0('create.',id),list(el))
s<-paste0('append.',id)
for (i in 1:n)
{
o<-do.call(s,list(o,el))
}
return(do.call(paste0('access.', id), list(o)))
}
Let's see the performance for n=10 insertions.
I also added a 'placebo' functions (with suffix 0
) that don't perform anything - just to measure the overhead of the test setup.
r<-microbenchmark(test(0,n=10), test(1,n=10),test(2,n=10),test(3,n=10), test(4,n=10))
autoplot(r)
For 1E5 rows (measurements done on Intel(R) Core(TM) i7-4710HQ CPU @ 2.50GHz):
nr function time

It looks like the SQLite-based sulution, although regains some speed on large data, is nowhere near data.table + manual exponential growth. The difference is almost two orders of magnitude!
If you know that you will append rather small number of rows (n<=100), go ahead and use the simplest possible solution: just assign the rows to the data.frame using bracket notation and ignore the fact that the data.frame is not pre-populated.
For everything else use data.table::set
and grow the data.table exponentially (e.g. using my code).
In command prompt go to the main directory you want the list for ... and type the command tree /f
do use the links above. If you run into error "This update is not applicable to your computer. " then make sure you are in fact using the right file for your os. for example i tried running windows 2012 server from that link on windows 7 service pack 1 and I got the above error so be sure to use the right zip. If you don't know which os you have then go to start and system and it should pop right up This should be self explanatory but
This is because you have not compiled it. Click 'Project > compile'. Then, either click 'start debugging', or 'start without debugging'.
Try This:
sqlplus -s ${ORA_CONN_STR} <<EOF >/dev/null
Try this code:--
UIImageView *imv = [[UIImageView alloc]initWithFrame:CGRectMake(3,2, 20, 25)];
imv.image=[UIImage imageNamed:@"arrow2.png"];
[cell addSubview:imv];
[imv release];
You can try to check if your web properties for the project didn't switch to IIS Express and change it back to IIS Local
The remainder of a division can be discovered using the operator %
:
>>> 26%7
5
In case you need both the quotient and the modulo, there's the builtin divmod
function:
>>> seconds= 137
>>> minutes, seconds= divmod(seconds, 60)
A good place to start is the sample application provided on the developer docs.
Take a look at other IME's to see what you should be aiming for. Some (like the official one) are open source.

I wrote a useful scalar function to simulate the TRY_CAST function of SQL SERVER 2012 in SQL Server 2008.
You can see it in the next link below and we help each other to improve it. TRY_CAST Function for SQL Server 2008 https://gist.github.com/jotapardo/800881eba8c5072eb8d99ce6eb74c8bb
The two main differences are that you must pass 3 parameters and you must additionally perform an explicit CONVERT or CAST to the field. However, it is still very useful because it allows you to return a default value if CAST is not performed correctly.
dbo.TRY_CAST(Expression, Data_Type, ReturnValueIfErrorCast)
Example:
SELECT CASE WHEN dbo.TRY_CAST('6666666166666212', 'INT', DEFAULT) IS NULL
THEN 'Cast failed'
ELSE 'Cast succeeded'
END AS Result;
For now only supports the data types INT, DATE, NUMERIC, BIT and FLOAT
I hope you find it useful.
CODE:
DECLARE @strSQL NVARCHAR(1000)
IF NOT EXISTS (SELECT * FROM dbo.sysobjects WHERE id = OBJECT_ID(N'[dbo].[TRY_CAST]'))
BEGIN
SET @strSQL = 'CREATE FUNCTION [dbo].[TRY_CAST] () RETURNS INT AS BEGIN RETURN 0 END'

Description:
Syntax
---------------
dbo.TRY_CAST(Expression, Data_Type, ReturnValueIfErrorCast)
+---------------------------+-----------------------+
| Expression | VARCHAR(8000) |
+---------------------------+-----------------------+
| Data_Type | VARCHAR(8000) |
+---------------------------+-----------------------+
| ReturnValueIfErrorCast | SQL_VARIANT = NULL |
+---------------------------+-----------------------+
Arguments
---------------
expression
The value to be cast. Any valid expression.
Data_Type
The data type into which to cast expression.
ReturnValueIfErrorCast
Value returned if cast fails or is not supported. Required. Set the DEFAULT value by default.
Return Type
----------------
Returns value cast to SQL_VARIANT type if the cast succeeds; otherwise, returns null if the parameter @pReturnValueIfErrorCast is set to DEFAULT,
or that the user indicates.
Remarks
----------------
dbo.TRY_CAST function simulates the TRY_CAST function reserved of SQL SERVER 2012 for using in SQL SERVER 2008.
dbo.TRY_CAST function takes the value passed to it and tries to convert it to the specified Data_Type.
If the cast succeeds, dbo.TRY_CAST returns the value as SQL_VARIANT type; if the cast doesn´t succees, null is returned if the parameter @pReturnValueIfErrorCast is set to DEFAULT.
If the Data_Type is unsupported will return @pReturnValueIfErrorCast.
dbo.TRY_CAST function requires user make an explicit CAST or CONVERT in ANY statements.
This version of dbo.TRY_CAST only supports CAST for INT, DATE, NUMERIC and BIT types.
Examples
====================================================================================================
--A. Test TRY_CAST function returns null

dbo.TRY_CAST('2147483648', 'INT', NULL) AS [Error Cast With User NULL Value];
GO
--C. Additional CAST or CONVERT required in any assignment statement
DECLARE @IntegerVariable AS INT

If you want to implement that yourself, the OAuth 2.0 flow for Web Server Applications is documented at https://developers.google.com/accounts/docs/OAuth2WebServer, in particular you should check the section about using a refresh token:
https://developers.google.com/accounts/docs/OAuth2WebServer#refresh
Like you said remote_repo_url
is indeed the IP of the server, and yes it needs to be added on each PC, but it's easier to understand if you create the server first then ask each to clone it.
There's several ways to connect to the server, you can use ssh, http, or even a network drive, each has it's pros and cons. You can refer to the documentation about protocols and how to connect to the server
You can check the rest of chapter 4 for more detailed information, as it's talking about how to set up your own server
If you need a recursive search, you have a variety of options. You should consider ack
.
Failing that, if you have GNU find
and xargs
:
find . -name '*.cc' -print0 -o -name '*.h' -print0 | xargs -0 grep hello /dev/null
The use of /dev/null
ensures you get file names printed; the -print0
and -0
deals with file names containing spaces (newlines, etc).
If you don't have obstreperous names (with spaces etc), you can use:
find . -name '*.*[ch]' -print | xargs grep hello /dev/null
This might pick up a few names you didn't intend, because the pattern match is fuzzier (but simpler), but otherwise works. And it works with non-GNU versions of find
and xargs
.
Use setState
in your view to change employed
property of state. This is example of React render engine.
someFunctionWhichChangeParamEmployed(isEmployed) {
this.setState({
employed: isEmployed
});
}
getInitialState() {
return {
employed: true
}
},
render(){
if (this.state.employed) {
return (
<div>
<MyInput ref="job-title" name="job-title" />
</div>
);
} else {
return (
<div>
<span>Diff me!</span>
<MyInput ref="unemployment-reason" name="unemployment-reason" />
<MyInput ref="unemployment-duration" name="unemployment-duration" />
</div>
);
}
}
for (Map.Entry<String, ArrayList<Integer>> entry : map.entrySet()) {
System.out.println( entry.getKey());
System.out.println( entry.getValue());//Returns the list of values
}
find supports wildcard matches, just add a *
:
find / -type d -name "ora10*"
777
is a permission in Unix based system with full read/write/execute permission to owner, group and everyone.. in general we give this permission to assets which are not much needed to be hidden from public on a web server, for example images..
You said I am using windows 7.
if that means that your web server is Windows based then you should login to that and right click the folder and set permissions to everyone
and if you are on a windows client and server is unix/linux based then use some ftp software and in the parent directory right click and change the permission for the folder.
If you want permission to be set on sub-directories
too then usually their is option to set permission recursively use that.
And, if you feel like doing it from command line the use putty and login to server and go to the parent directory includes
and write the following command

If you are using AWS Lambda with SprintBoot, then you must declare the following under environment variables:
key: JAVA_TOOL_OPTIONS & value: -Dspring.profiles.active=dev
You can use ng-repeat
and pick data only if data matches what you are looking for using ng-show
for example:
<div ng-repeat="data in res.results" ng-show="data.id==1">
{{data.name}}
</div>
This code is actually used to add values to the dictionary
and through
the data to an Array
According to the Key
.
NSMutableArray *arr = [[NSMutableArray alloc]init];
NSDictionary *dicto = [[NSMutableDictionary alloc]initWithObjectsAndKeys:@"Hello",@"StackOverFlow",@"Key1",@"StackExchange",@"Key2", nil];
NSLog(@"The dictonary is = %@", dicto);
arr = [dicto valueForKey:@"Key1"];
NSLog(@"The array is = %@", arr);
Cheatsheet to prepend new element(s) into the array
const list = [23, 45, 12, 67];
list.unshift(34);
console.log(list); // [34, 23, 45, 12, 67];

2. Array#splice
const list = [23, 45, 12, 67];
list.splice(0, 0, 34);
console.log(list); // [34, 23, 45, 12, 67];
_x000D_
const list = [23, 45, 12, 67];
const newList = [34, ...list];
console.log(newList); // [34, 23, 45, 12, 67];
_x000D_
4. Array#concat
const list = [23, 45, 12, 67];
const newList = [32].concat(list);
console.log(newList); // [34, 23, 45, 12, 67];

Note: In each of these examples, you can prepend multiple items by providing more items to insert.
Your problem is that you are naming your component class Date
. When you call new Date()
within your class, it won't create an instance of the Date
you expect it to create (which is likely this Date
)- it will try to create an instance of your component class. Then the constructor will try to create another instance, and another instance, and another instance... Until you run out of stack space and get the error you're seeing.
If you want to use Date
within your class, try naming your class something different such as Calendar
or DateComponent
.
The reason for this is how JavaScript deals with name scope: Whenever you create a new named entity, if there is already an entity with that name in scope, that name will stop referring to the previous entity and start referring to your new entity. So if you use the name Date
within a class named Date
, the name Date
will refer to that class and not to any object named Date
which existed before the class definition started.

- computing x^N,
O(N Log N)
- Longest increasing subsequence
