You can use Regular Expressions
if(System.Text.RegularExpressions.IsMatch("a|b|c"))
I think that your problem was emerged from typescript and module version mismatch.This issue is very similar to your question and answers are very satisfying.
The following query produces a(nother) query that will get the value of count(*) for every table, from every schema, listed in information_schema.tables. The entire result of the query shown here - all rows taken together - comprise a valid SQL statement ending in a semicolon - no dangling 'union'. The dangling union is avoided by use of a union in the query below.
select concat('select "', table_schema, '.', table_name, '" as `schema.table`,
count(*)
from ', table_schema, '.', table_name, ' union ') as 'Query Row'
from information_schema.tables
union
select '(select null, null limit 0);';
In swift 4.2 I used following code to show and hide code using NSNotification
@objc func keyboardWillShow(notification: NSNotification) {
if let keyboardSize = (notification.userInfo? [UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
let keyboardheight = keyboardSize.height
print(keyboardheight)
}
}
Pure numpy
numpy.loadtxt(open("test.csv", "rb"), delimiter=",", skiprows=1)
Check out the loadtxt documentation.
You can also use python's csv module:
import csv
import numpy
reader = csv.reader(open("test.csv", "rb"), delimiter=",")
x = list(reader)
result = numpy.array(x).astype("float")
You will have to convert it to your favorite numeric type. I guess you can write the whole thing in one line:
result = numpy.array(list(csv.reader(open("test.csv", "rb"), delimiter=","))).astype("float")
Added Hint:
You could also use pandas.io.parsers.read_csv
and get the associated numpy
array which can be faster.
I find another solution:
<input type="text" class="disabled" name="test" value="test" />
Class "disabled" immitate disabled element by opacity:
<style type="text/css">
input.disabled {
opacity: 0.5;
}
</style>
And then cancel the event if element is disabled and remove class:
$(document).on('click','input.disabled',function(event) {
event.preventDefault();
$(this).removeClass('disabled');
});
Are you using the @ symbol anywhere?
If you have something like:
@include('page_with_error.php');
You will get a blank page.
As bash does not have a built-in value in
array operator and the =~
operator or the [[ "${array[@]" == *"${item}"* ]]
notation keep confusing me, I usually combine grep
with a here-string:
colors=('black' 'blue' 'light green')
if grep -q 'black' <<< "${colors[@]}"
then
echo 'match'
fi
Beware however that this suffers from the same false positives issue as many of the other answers that occurs when the item to search for is fully contained, but is not equal to another item:
if grep -q 'green' <<< "${colors[@]}"
then
echo 'should not match, but does'
fi
If that is an issue for your use case, you probably won't get around looping over the array:
for color in "${colors[@]}"
do
if [ "${color}" = 'green' ]
then
echo "should not match and won't"
break
fi
done
for color in "${colors[@]}"
do
if [ "${color}" = 'light green' ]
then
echo 'match'
break
fi
done
MAT, jprofiler,jhat are possible options. since jhat comes with jdk, you can easily launch it to do some basic analysis. check this out
root.configure(background='black')
or more generally
<widget>.configure(background='black')
You can simply do a replace in your string like
Str.Replace(@"\\",@"\");
Mockito matchers are static methods and calls to those methods, which stand in for arguments during calls to when
and verify
.
Hamcrest matchers (archived version) (or Hamcrest-style matchers) are stateless, general-purpose object instances that implement Matcher<T>
and expose a method matches(T)
that returns true if the object matches the Matcher's criteria. They are intended to be free of side effects, and are generally used in assertions such as the one below.
/* Mockito */ verify(foo).setPowerLevel(gt(9000));
/* Hamcrest */ assertThat(foo.getPowerLevel(), is(greaterThan(9000)));
Mockito matchers exist, separate from Hamcrest-style matchers, so that descriptions of matching expressions fit directly into method invocations: Mockito matchers return T
where Hamcrest matcher methods return Matcher objects (of type Matcher<T>
).
Mockito matchers are invoked through static methods such as eq
, any
, gt
, and startsWith
on org.mockito.Matchers
and org.mockito.AdditionalMatchers
. There are also adapters, which have changed across Mockito versions:
Matchers
featured some calls (such as intThat
or argThat
) are Mockito matchers that directly accept Hamcrest matchers as parameters. ArgumentMatcher<T>
extended org.hamcrest.Matcher<T>
, which was used in the internal Hamcrest representation and was a Hamcrest matcher base class instead of any sort of Mockito matcher.Matchers
calls phrased as intThat
or argThat
wrap ArgumentMatcher<T>
objects that no longer implement org.hamcrest.Matcher<T>
but are used in similar ways. Hamcrest adapters such as argThat
and intThat
are still available, but have moved to MockitoHamcrest
instead.Regardless of whether the matchers are Hamcrest or simply Hamcrest-style, they can be adapted like so:
/* Mockito matcher intThat adapting Hamcrest-style matcher is(greaterThan(...)) */
verify(foo).setPowerLevel(intThat(is(greaterThan(9000))));
In the above statement: foo.setPowerLevel
is a method that accepts an int
. is(greaterThan(9000))
returns a Matcher<Integer>
, which wouldn't work as a setPowerLevel
argument. The Mockito matcher intThat
wraps that Hamcrest-style Matcher and returns an int
so it can appear as an argument; Mockito matchers like gt(9000)
would wrap that entire expression into a single call, as in the first line of example code.
when(foo.quux(3, 5)).thenReturn(true);
When not using argument matchers, Mockito records your argument values and compares them with their equals
methods.
when(foo.quux(eq(3), eq(5))).thenReturn(true); // same as above
when(foo.quux(anyInt(), gt(5))).thenReturn(true); // this one's different
When you call a matcher like any
or gt
(greater than), Mockito stores a matcher object that causes Mockito to skip that equality check and apply your match of choice. In the case of argumentCaptor.capture()
it stores a matcher that saves its argument instead for later inspection.
Matchers return dummy values such as zero, empty collections, or null
. Mockito tries to return a safe, appropriate dummy value, like 0 for anyInt()
or any(Integer.class)
or an empty List<String>
for anyListOf(String.class)
. Because of type erasure, though, Mockito lacks type information to return any value but null
for any()
or argThat(...)
, which can cause a NullPointerException if trying to "auto-unbox" a null
primitive value.
Matchers like eq
and gt
take parameter values; ideally, these values should be computed before the stubbing/verification starts. Calling a mock in the middle of mocking another call can interfere with stubbing.
Matcher methods can't be used as return values; there is no way to phrase thenReturn(anyInt())
or thenReturn(any(Foo.class))
in Mockito, for instance. Mockito needs to know exactly which instance to return in stubbing calls, and will not choose an arbitrary return value for you.
Matchers are stored (as Hamcrest-style object matchers) in a stack contained in a class called ArgumentMatcherStorage. MockitoCore and Matchers each own a ThreadSafeMockingProgress instance, which statically contains a ThreadLocal holding MockingProgress instances. It's this MockingProgressImpl that holds a concrete ArgumentMatcherStorageImpl. Consequently, mock and matcher state is static but thread-scoped consistently between the Mockito and Matchers classes.
Most matcher calls only add to this stack, with an exception for matchers like and
, or
, and not
. This perfectly corresponds to (and relies on) the evaluation order of Java, which evaluates arguments left-to-right before invoking a method:
when(foo.quux(anyInt(), and(gt(10), lt(20)))).thenReturn(true);
[6] [5] [1] [4] [2] [3]
This will:
anyInt()
to the stack.gt(10)
to the stack.lt(20)
to the stack.gt(10)
and lt(20)
and add and(gt(10), lt(20))
.foo.quux(0, 0)
, which (unless otherwise stubbed) returns the default value false
. Internally Mockito marks quux(int, int)
as the most recent call.when(false)
, which discards its argument and prepares to stub method quux(int, int)
identified in 5. The only two valid states are with stack length 0 (equality) or 2 (matchers), and there are two matchers on the stack (steps 1 and 4), so Mockito stubs the method with an any()
matcher for its first argument and and(gt(10), lt(20))
for its second argument and clears the stack.This demonstrates a few rules:
Mockito can't tell the difference between quux(anyInt(), 0)
and quux(0, anyInt())
. They both look like a call to quux(0, 0)
with one int matcher on the stack. Consequently, if you use one matcher, you have to match all arguments.
Call order isn't just important, it's what makes this all work. Extracting matchers to variables generally doesn't work, because it usually changes the call order. Extracting matchers to methods, however, works great.
int between10And20 = and(gt(10), lt(20));
/* BAD */ when(foo.quux(anyInt(), between10And20)).thenReturn(true);
// Mockito sees the stack as the opposite: and(gt(10), lt(20)), anyInt().
public static int anyIntBetween10And20() { return and(gt(10), lt(20)); }
/* OK */ when(foo.quux(anyInt(), anyIntBetween10And20())).thenReturn(true);
// The helper method calls the matcher methods in the right order.
The stack changes often enough that Mockito can't police it very carefully. It can only check the stack when you interact with Mockito or a mock, and has to accept matchers without knowing whether they're used immediately or abandoned accidentally. In theory, the stack should always be empty outside of a call to when
or verify
, but Mockito can't check that automatically.
You can check manually with Mockito.validateMockitoUsage()
.
In a call to when
, Mockito actually calls the method in question, which will throw an exception if you've stubbed the method to throw an exception (or require non-zero or non-null values).
doReturn
and doAnswer
(etc) do not invoke the actual method and are often a useful alternative.
If you had called a mock method in the middle of stubbing (e.g. to calculate an answer for an eq
matcher), Mockito would check the stack length against that call instead, and likely fail.
If you try to do something bad, like stubbing/verifying a final method, Mockito will call the real method and also leave extra matchers on the stack. The final
method call may not throw an exception, but you may get an InvalidUseOfMatchersException from the stray matchers when you next interact with a mock.
InvalidUseOfMatchersException:
Check that every single argument has exactly one matcher call, if you use matchers at all, and that you haven't used a matcher outside of a when
or verify
call. Matchers should never be used as stubbed return values or fields/variables.
Check that you're not calling a mock as a part of providing a matcher argument.
Check that you're not trying to stub/verify a final method with a matcher. It's a great way to leave a matcher on the stack, and unless your final method throws an exception, this might be the only time you realize the method you're mocking is final.
NullPointerException with primitive arguments: (Integer) any()
returns null while any(Integer.class)
returns 0; this can cause a NullPointerException
if you're expecting an int
instead of an Integer. In any case, prefer anyInt()
, which will return zero and also skip the auto-boxing step.
NullPointerException or other exceptions: Calls to when(foo.bar(any())).thenReturn(baz)
will actually call foo.bar(null)
, which you might have stubbed to throw an exception when receiving a null argument. Switching to doReturn(baz).when(foo).bar(any())
skips the stubbed behavior.
Use MockitoJUnitRunner, or explicitly call validateMockitoUsage
in your tearDown
or @After
method (which the runner would do for you automatically). This will help determine whether you've misused matchers.
For debugging purposes, add calls to validateMockitoUsage
in your code directly. This will throw if you have anything on the stack, which is a good warning of a bad symptom.
They're not synonyms - display: none
removes the element from the flow of the page, and rest of the page flows as if it weren't there.
visibility: hidden
hides the element from view but not the page flow, leaving space for it on the page.
The answer is NO you can't. Why?
Because the LDAP standard describes a LDAP-SEARCH as kind of function with 4 parameters:
You are interested in the filter. You've got a summary here (it's provided by Microsoft for Active Directory, it's from a standard). The filter is composed, in a boolean way, by expression of the type Attribute Operator Value
.
So the filter you give does not mean anything.
On the theoretical point of view there is ExtensibleMatch that allows buildind filters on the DN path, but it's not supported by Active Directory.
As far as I know, you have to use an attribute in AD to make the distinction for users in the two OUs.
It can be any existing discriminator attribute, or, for example the attribute called OU which is inherited from organizationalPerson
class. you can set it (it's not automatic, and will not be maintained if you move the users) with "staff" for some users and "vendors" for others and them use the filter:
(&(objectCategory=person)(|(ou=staff)(ou=vendors)))
Here's what's this TS snippet compiled into (via TS Playground):
define(["require", "exports"], function(require, exports) {
var Library = (function () {
function Library() {
}
Library.BOOK_SHELF_NONE = "None";
Library.BOOK_SHELF_FULL = "Full";
return Library;
})();
exports.Library = Library;
});
As you see, both properties defined as public static
are simply attached to the exported function (as its properties); therefore they should be accessible as long as you properly access the function itself.
I use :
int convertToInt(char a[1000]){
int i = 0;
int num = 0;
while (a[i] != 0)
{
num = (a[i] - '0') + (num * 10);
i++;
}
return num;;
}

//send messages or some other action
}
public void onFinish() {
//After 60000 milliseconds (60 sec) finish current
//if you would like to execute something when time finishes
}
}.start();
to stop the timer early:
if(waitTimer != null) {
waitTimer.cancel();
waitTimer = null;
}

Just subtract the string address from what strchr returns:
char *string = "qwerty";
char *e;
int index;
e = strchr(string, 'e');
index = (int)(e - string);
Note that the result is zero based, so in above example it will be 2.
I got same error. This is how it worked for me:
Worked perfectly!
Do this :
$(document).ready(function(){

This is still not fixed in Xcode Version 8.0 beta 2 (8S162m) for me and extra logs are also appearing in the Xcode console
** EDIT 8/1/16: This has been acknowledged in the release notes for Xcode 8 Beta 4 (8S188o) as an issues still persisting.
Known Issues in Xcode 8 beta 4 – IDE
Debugging
• Xcode Debug Console shows extra logging from system frameworks when debugging applications in the Simulator. (27331147, 26652255)
Presumably this will be resolved by the GM release. Until then patience and although not ideal but a workaround I'm using is below...
Similar to the previous answer I am having to:
prefix my print logs with some kind of special character (eg * or ^ or ! etc etc)
Then use the search box on the bottom right of the console pane to filter my console logs by inputing my chosen special character to get the console to display my print logs as intended
What about:
@echo off
set myvar="the list: "
for /r %%i in (*.doc) DO call :concat %%i
echo %myvar%
goto :eof
:concat
set myvar=%myvar% %1;
goto :eof
This solution gives correct results over the entire range [0,UINT_MAX] without requiring digits to be buffered.
It also works for wider types or signed types (with positive values) with appropriate type changes.
This kind of approach is particularly useful on tiny environments (e.g. Arduino bootloader) because it doesn't end up pulling in all the printf() bloat (when printf() isn't used for demo output) and uses very little RAM. You can get a look at value just by blinking a single led :)
#include <limits.h>
#include <stdio.h>
int
main (void)
{
unsigned int score = 42; // Works for score in [0, UINT_MAX]
printf ("score via printf: %u\n", score); // For validation
printf ("score digit by digit: ");
unsigned int div = 1;
unsigned int digit_count = 1;
while ( div <= score / 10 ) {
digit_count++;
div *= 10;
}
while ( digit_count > 0 ) {
printf ("%d", score / div);
score %= div;
div /= 10;
digit_count--;
}
printf ("\n");
return 0;
}
I believe this should solve your problem. I may be missing a few edge cases, please comment if you notice one.
You need a way to exclude previous substitutions from future patterns, which really means making outputs distinguishable, as well as excluding these outputs from your searches, and finally making outputs indistinguishable again. This is very similar to the quoting/escaping process, so I'll draw from it.
s/\\/\\\\/g
escapes all existing backslashess/ab/\\b\\c/g
substitutes raw ab for escaped bcs/bc/\\a\\b/g
substitutes raw bc for escaped abs/\\\(.\)/\1/g
substitutes all escaped X for raw XI have not accounted for backslashes in ab or bc, but intuitively, I would escape the search and replace terms the same way - \
now matches \\
, and substituted \\
will appear as \
.
Until now I have been using backslashes as the escape character, but it's not necessarily the best choice. Almost any character should work, but be careful with the characters that need escaping in your environment, sed, etc. depending on how you intend to use the results.
Instead of adding "ws." before every Range, as suggested above, you can add "ws.activate" before Call instead.
This will get you into the worksheet you want to work on.
I believe all the existing answers contain the relevant information, but I would like to summarize.
The response object that is returned by requests
get and post operations contains two useful attributes:
response.text
- Contains str
with the response text.response.content
- Contains bytes
with the raw response content.You should choose one or other of these attributes depending on the type of response you expect.
response.text
response.content
.When writing responses to file you need to use the open function with the appropriate file write mode.
"w"
- plain write mode."wb"
- binary write mode.# Request the HTML for this web page:
response = requests.get("https://stackoverflow.com/questions/31126596/saving-response-from-requests-to-file")
with open("response.txt", "w") as f:
f.write(response.text)
# Request the profile picture of the OP:
response = requests.get("https://i.stack.imgur.com/iysmF.jpg?s=32&g=1")
with open("response.jpg", "wb") as f:
f.write(response.content)
The original code should work by using wb
and response.content
:
import requests
files = {'f': ('1.pdf', open('1.pdf', 'rb'))}
response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)
response.raise_for_status() # ensure we notice bad responses
file = open("out.xls", "wb")
file.write(response.content)
file.close()
But I would go further and use the with
context manager for open
.
import requests
with open('1.pdf', 'rb') as file:
files = {'f': ('1.pdf', file)}
response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)
response.raise_for_status() # ensure we notice bad responses
with open("out.xls", "wb") as file:
file.write(response.content)
{ "date" : "1000000" }
in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }
It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback)
and if that works, you have a typing issue.

Go to management studio and do everything you describe, only instead of clicking OK, click on Script. It will show the code it will run which you can then incorporate in your scripts.
In this case, you want:
ALTER DATABASE [MyDatabase] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
GO
var scrollBottom =
$(document).height() - $(window).height() - $(window).scrollTop();
I think it is better to get bottom scroll.
Instead of changing the COM port in Device manager, if you're using the Arduino software, I had to set the port in Tools > Port menu.
Slightly off topic, but have you considered Windows Scripting Host? You might find it nicer.
IValueConverter implementation can be used. Converter class which takes inheritance from IValueConverter takes some parameters like value
(percentage) and parameter
(parent's width) and returns desired width value. In XAML file, component's width is set with the desired value:
public class SizePercentageConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
if (parameter == null)
return 0.7 * value.ToDouble();
string[] split = parameter.ToString().Split('.');
double parameterDouble = split[0].ToDouble() + split[1].ToDouble() / (Math.Pow(10, split[1].Length));
return value.ToDouble() * parameterDouble;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
// Don't need to implement this
return null;
}
}
XAML:
<UserControl.Resources>
<m:SizePercentageConverter x:Key="PercentageConverter" />
</UserControl.Resources>
<ScrollViewer VerticalScrollBarVisibility="Auto"
HorizontalScrollBarVisibility="Disabled"
Width="{Binding Converter={StaticResource PercentageConverter}, RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type Border}},Path=ActualWidth}"
Height="{Binding Converter={StaticResource PercentageConverter}, ConverterParameter=0.6, RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type Border}},Path=ActualHeight}">

I would not have expected this case to be optimized at all. It can't be very often where an expression contains subexpressions that can be regrouped to remove entire operations. I would expect compiler writers to invest their time in areas which would be more likely to result in noticeable improvements, rather than covering a rarely encountered edge case.
I was surprised to learn from the other answers that this expression could indeed be optimized with the proper compiler switches. Either the optimization is trivial, or it is an edge case of a much more common optimization, or the compiler writers were extremely thorough.
There's nothing wrong with providing hints to the compiler as you've done here. It's a normal and expected part of the micro-optimization process to rearrange statements and expressions to see what differences they will bring.
While the compiler may be justified in considering the two expressions to deliver inconsistent results (without the proper switches), there's no need for you to be bound by that restriction. The difference will be incredibly tiny - so much so that if the difference matters to you, you should not be using standard floating point arithmetic in the first place.
As of iOS 5 this one is far more easy:

vector<char> toVector( const std::string& s ) {
string s = "apple";
vector<char> v(s.size()+1);
memcpy( &v.front(), s.c_str(), s.size() + 1 );
return v;
}
vector<char> v = toVector(std::string("apple"));
// what you were looking for (mutable)
char* c = v.data();
.c_str() works for immutable. The vector will manage the memory for you.
Standard SQL provides the MERGE statement for this task. Not all DBMS support the MERGE statement.
The problem is that these two queries are each returning more than one row:
select isbn from dbo.lending where (act between @fdate and @tdate) and (stat ='close')
select isbn from dbo.lending where lended_date between @fdate and @tdate
You have two choices, depending on your desired outcome. You can either replace the above queries with something that's guaranteed to return a single row (for example, by using SELECT TOP 1
), OR you can switch your =

You can use "lsof" to find open logfiles on your system. lsof just gives you a list of all open files.
Use grep for "log" ... use grep again for "php" (if the filename contains the strings "log" and "php" like in "php_error_log" and you are root user you will find the files without knowing the configuration).
root@lnx-work:~# lsof |grep log

I solved this on 12.10 by installing libssl-dev.
sudo apt-get install libssl-dev
Clean your maven cache and rerun:
mvn dependency:purge-local-repository
For unique salaries (i.e. first can't be same as second):
SELECT
MAX( s.salary ) AS max_salary,
(SELECT
MAX( salary )
FROM salaries
WHERE salary <> MAX( s.salary )
ORDER BY salary DESC
LIMIT 1
) AS 2nd_max_salary
FROM salaries s
And also because it's such an unnecessary way to go about solving this problem (Can anyone say 2 rows instead of 2 columns, LOL?)
It's time to add some lambdas:
codes.entrySet()
.stream()
.sorted(Comparator.comparing(Map.Entry::getValue))
.forEach(System.out::println);
To add to the accepted answer:
Bear in mind that set -e
sometimes is not enough, specially if you have pipes.
For example, suppose you have this script
#!/bin/bash
set -e
./configure > configure.log
make
... which works as expected: an error in configure
aborts the execution.
Tomorrow you make a seemingly trivial change:
#!/bin/bash
set -e
./configure | tee configure.log
make
... and now it does not work. This is explained here, and a workaround (Bash only) is provided:
#!/bin/bash set -e set -o pipefail ./configure | tee configure.log make
From the comments to the original question, it seems that you have multiple versions of python installed and that pip just goes to the wrong version.
First, to know which version of python you're using, just type which python
. You should either see:
which python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python
if you're going to the right version of python, or:
which python
/usr/bin/python
If you're going to the 'wrong' version. To make pip go to the right version, you first have to change the path:
export PATH=/Library/Frameworks/Python.framework/Versions/2.7/bin/python:${PATH}
typing 'which python' would now get you to the right result. Next, install pip (if it's not already installed for this installation of python). Finally, use it. you should be fine now.
Yep it is here, using _.reduce
var params = [
{ name: 'foo', input: 'bar' },
{ name: 'baz', input: 'zle' }
];
_.reduce(params , function(obj,param) {
obj[param.name] = param.input
return obj;
}, {});
If you don't want to keep track of moving your fonts around:
# Adding Webfonts to the Asset Pipeline
config.assets.precompile << Proc.new { |path|
if path =~ /\.(eot|svg|ttf|woff)\z/
true
end
}
char* data;
std::string myString(data);
I used this question as a starting point for my own solution. Thought it was appropriate to contribute my code back since its smaller than tabacitu's

Steps to generate Create table DDLs for all the tables in the Hive database and export into text file to run later:
step 1)
create a .sh
file with the below content, say hive_table_ddl.sh
#!/bin/bash
rm -f tableNames.txt
rm -f HiveTableDDL.txt
hive -e "use $1; show tables;" > tableNames.txt
wait
cat tableNames.txt |while read LINE
do
hive -e "use $1;show create table $LINE;" >>HiveTableDDL.txt
echo -e "\n" >> HiveTableDDL.txt
done
rm -f tableNames.txt
echo "Table DDL generated"
step 2)
Run the above shell script by passing 'db name' as paramanter
>bash hive_table_dd.sh <<databasename>>
output :
All the create table statements of your DB will be written into the HiveTableDDL.txt
To get the 2 chars ISO 639-1 language identifier use:
System.Threading.Thread.CurrentThread.CurrentCulture.TwoLetterISOLanguageName;
Or using lambda function, like
>>> vec = np.arange(0,27,3).reshape(3,3)
>>> import numpy as np
>>> norm_vec = map(lambda row: row/np.linalg.norm(row), vec)
each vector of vec will have a unit norm.
I think this is a simple code in java which will show the string value in CSV after compile this code.
public class CsvWriter {
public static void main(String args[]) {
// File input path
System.out.println("Starting....");
File file = new File("/home/Desktop/test/output.csv");
try {
FileWriter output = new FileWriter(file);
CSVWriter write = new CSVWriter(output);
// Header column value
String[] header = { "ID", "Name", "Address", "Phone Number" };
write.writeNext(header);
// Value
String[] data1 = { "1", "First Name", "Address1", "12345" };
write.writeNext(data1);
String[] data2 = { "2", "Second Name", "Address2", "123456" };
write.writeNext(data2);
String[] data3 = { "3", "Third Name", "Address3", "1234567" };
write.writeNext(data3);
write.close();
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
System.out.println("End.");
}
}
The method System.Web.UI.Page.RegisterClientScriptBlock has been deprecated for some time (along with the other Page.Register* methods), ever since .NET 2.0 as shown by MSDN.
Instead use the .NET 2.0 Page.ClientScript.Register* methods. - (The ClientScript property expresses an instance of the ClientScriptManager class )
Guessing the problem
If you are saying your JavaScript alert box occurs before the page's content is visibly rendered, and therefore the page remains white (or still unrendered) when the alert box is dismissed by the user, then try using the Page.ClientScript.RegisterStartupScript(..) method instead because it runs the given client-side code when the page finishes loading - and its arguments are similar to what you're using already.
Also check for general JavaScript errors in the page - this is often seen by an error icon in the browser's status bar. Sometimes a JavaScript error will hold up or disturb unrelated elements on the page.
There should be a default active record behavior on this I reckon. Querying dates is hard, especially when timezones are involved.
Anyway, I use:
scope :between, ->(start_date=nil, end_date=nil) {
if start_date && end_date
where("#{self.table_name}.created_at BETWEEN :start AND :end", start: start_date.beginning_of_day, end: end_date.end_of_day)
elsif start_date
where("#{self.table_name}.created_at >= ?", start_date.beginning_of_day)
elsif end_date
where("#{self.table_name}.created_at <= ?", end_date.end_of_day)
else
all
end
}
You can check this way too
<c:if test="${theBooleanVariable ne true}">It's false!</c:if>
This can help others a lot!
First:
private static final String APP_DIR = Environment.getExternalStorageDirectory().getAbsolutePath() + "/MyAppFolderInStorage/";
private void install() {
File file = new File(APP_DIR + fileName);
if (file.exists()) {
Intent intent = new Intent(Intent.ACTION_VIEW);
String type = "application/vnd.android.package-archive";
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
Uri downloadedApk = FileProvider.getUriForFile(getContext(), "ir.greencode", file);
intent.setDataAndType(downloadedApk, type);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
} else {
intent.setDataAndType(Uri.fromFile(file), type);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
}
getContext().startActivity(intent);
} else {
Toast.makeText(getContext(), "?File not found!", Toast.LENGTH_SHORT).show();
}
}
Second: For android 7 and above you should define a provider in manifest like below!
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="ir.greencode"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/paths" />
</provider>
Third: Define path.xml in res/xml folder like below! I'm using this path for internal storage if you want to change it to something else there is a few way! You can go to this link: FileProvider
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="your_folder_name" path="MyAppFolderInStorage/"/>
</paths>
Forth: You should add this permission in manifest:
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/>
Allows an application to request installing packages. Apps targeting APIs greater than 25 must hold this permission in order to use Intent.ACTION_INSTALL_PACKAGE.
Please make sure the provider authorities are the same!
In Java, items with the final
modifier cannot be changed!
This includes final classes, final variables, and final methods:
Still broken? Try uninstalling @types/moment
.
So, I removed @types/moment
package from the package.json
file and it worked using:
import * as moment from 'moment'
Newer versions of moment
don't require the @types/moment
package as types are already included.
What is the datatype for column1 in your Hive table? Please note that if your column is STRING it won't be having a NULL value even though your external file does not have any data for that column.
Why not execute in backticks ?
x=`echo "$y" | tr '[:upper:]' '[:lower:]'`
This assigns the result of the command in backticks to the variable x
. (i.e. it's not particular to tr
but is a common pattern/solution for shell scripting)
You can use $(..)
instead of the backticks. See here for more info.
Not sure if that might really help you but that's how caching should work on any browser. When the browser request a file, it should always send a request to the server unless there is a "offline" mode. The server will read some parameters like date modified or etags.
The server will return a 304 error response for NOT MODIFIED and the browser will have to use its cache. If the etag doesn't validate on server side or the modified date is below the current modified date, the server should return the new content with the new modified date or etags or both.
If there is no caching data sent to the browser, I guess the behavior is undetermined, the browser may or may not cache file that don't tell how they are cached. If you set caching parameters in the response it will cache your files correctly and the server then may choose to return a 304 error, or the new content.
This is how it should be done. Using random params or version number in urls is more like a hack than anything.
http://www.checkupdown.com/status/E304.html http://en.wikipedia.org/wiki/HTTP_ETag http://www.xpertdeveloper.com/2011/03/last-modified-header-vs-expire-header-vs-etag/
After reading I saw that there is also a expire date. If you have problem, it might be that you have a expire date set up. In other words, when the browser will cache your file, since it has a expiry date, it shouldn't have to request it again before that date. In other words, it will never ask the file to the server and will never receive a 304 not modified. It will simply use the cache until the expiry date is reached or cache is cleared.
So that is my guess, you have some sort of expiry date and you should use last-modified etags or a mix of it all and make sure that there is no expire date.
If people tends to refresh a lot and the file doesn't get changed a lot, then it might be wise to set a big expiry date.
My 2 cents!
Example for Hamcrest:
import org.hamcrest.CoreMatchers
import org.hamcrest.MatcherAssert
import org.junit.jupiter.api.Test
class HamcrestAssertionDemo {
@Test
fun assertWithHamcrestMatcher() {
val subClass = SubClass()
MatcherAssert.assertThat(subClass, CoreMatchers.instanceOf<Any>(BaseClass::class.java))
}
}
Example for AssertJ:
import org.assertj.core.api.Assertions.assertThat
import org.junit.jupiter.api.Test
class AssertJDemo {
@Test
fun assertWithAssertJ() {
val subClass = SubClass()
assertThat(subClass).isInstanceOf(BaseClass::class.java)
}
}
Without any imports, but also incompatible with imported modules:
try:
raise TypeError("Hello, World!") # line 2
except Exception as e:
print(
type(e).__name__, # TypeError
__file__, # /tmp/example.py
e.__traceback__.tb_lineno # 2
)
$ python3 /tmp/example.py
TypeError /tmp/example.py 2
To reiterate, this does not work across import
s or modules, so if you do import X; try: X.example();
then the filename and line number will point to the line containing X.example()
instead of the line where it went wrong within X.example()
. If anyone knows how to easily get the file name and line number from the last stack trace line (I expected something like e[-1].filename
, but no such luck), please improve this answer.

There is a command line argument parser at http://www.codeplex.com/commonlibrarynet
It can parse arguments using
1. attributes
2. explicit calls
3. single line of multiple arguments OR string array
It can handle things like the following:
-config:Qa -startdate:${today} -region:'New York' Settings01
It's very easy to use.
Strings can be deep copied with
List<String> b = new ArrayList<String>(a);
because they are immutable. Every other Object not --> you need to iterate and do a copy by yourself.
I believe a lot of programmers have run into one or two interview problems where they are asked to deep copy a linked list, however this problem is harder than it sounds!
in python, there is a module called "copy" with two useful functions
import copy
copy.copy()
copy.deepcopy()
copy() is a shallow copy function, if the given argument is a compound data structure, for instance a list, then python will create another object of the same type (in this case, a new list) but for everything inside old list, only their reference is copied
# think of it like
newList = [elem for elem in oldlist]
Intuitively, we could assume that deepcopy() would follow the same paradigm, and the only difference is that for each elem we will recursively call deepcopy, (just like the answer of mbcoder)
but this is wrong!
deepcopy() actually preserve the graphical structure of the original compound data:
a = [1,2]
b = [a,a] # there's only 1 object a
c = deepcopy(b)
# check the result
c[0] is a # return False, a new object a' is created
c[0] is c[1] # return True, c is [a',a'] not [a',a'']
this is the tricky part, during the process of deepcopy() a hashtable(dictionary in python) is used to map: "old_object ref onto new_object ref", this prevent unnecessary duplicates and thus preserve the structure of the copied compound data
lastInsertId() only work after the INSERT query.
Correct:
$stmt = $this->conn->prepare("INSERT INTO users(userName,userEmail,userPass)
VALUES(?,?,?);");
$sonuc = $stmt->execute([$username,$email,$pass]);
$LAST_ID = $this->conn->lastInsertId();
Incorrect:
$stmt = $this->conn->prepare("SELECT * FROM users");
$sonuc = $stmt->execute();
$LAST_ID = $this->conn->lastInsertId(); //always return string(1)=0
use a HEREDOC, which eliminates any need to swap quote types and/or escape them:
echo <<<EOL
<script>$('#edit_errors').html('<h3><em><font color="red">Please Correct Errors Before Proceeding</font></em></h3>')</script>
EOL;
help(input)
shows what keyboard shortcuts produce EOF, namely, Unix: Ctrl-D, Windows: Ctrl-Z+Return:
input([prompt]) -> string
Read a string from standard input. The trailing newline is stripped. If the user hits EOF (Unix: Ctl-D, Windows: Ctl-Z+Return), raise EOFError. On Unix, GNU readline is used if enabled. The prompt string, if given, is printed without a trailing newline before reading.
You could reproduce it using an empty file:
$ touch empty
$ python3 -c "input()" < empty
Traceback (most recent call last):
File "<string>", line 1, in <module>
EOFError: EOF when reading a line
You could use /dev/null
or nul
(Windows) as an empty file for reading. os.devnull
shows the name that is used by your OS:
$ python3 -c "import os; print(os.devnull)"
/dev/null
Note: input()
happily accepts input from a file/pipe. You don't need stdin
to be connected to the terminal:
$ echo abc | python3 -c "print(input()[::-1])"
cba
Either handle EOFError
in your code:
try:
reply = input('Enter text')
except EOFError:
break
Or configure your editor to provide a non-empty input when it runs your script e.g., by using a customized command line if it allows it: python3 "%f" < input_file
Ruslik's suggestion to use source generation seems like a good thing to me. However, I wouldn't go with the concept of "main" and "generated" source files. I'd rather have one file with code almost identical to yours:
h=_myhash (mystring);
switch (h)
{
case 66452: // = hash("Vasia")
.......
case 1342537: // = hash("Petya")
........
}
The next thing I'd do, I'd write a simple script. Perl is good for such kind of things, but nothing stops you even from writing a simple program in C/C++ if you don't want to use any other languages. This script, or program, would take the source file, read it line-by-line, find all those case NUMBERS: // = hash("SOMESTRING")
lines (use regular expressions here), replace NUMBERS with the actual hash value and write the modified source into a temporary file. Finally, it would back up the source file and replace it with the temporary file. If you don't want your source file to have a new time stamp each time, the program could check if something was actually changed and if not, skip the file replacement.
The last thing to do is to integrate this script into the build system used, so you won't accidentally forget to launch it before building the project.
Try MySQL Workbench. It packs in very nice data modeling tools. Check out their screenshots for EER diagrams (Enhanced Entity Relationships, which are a notch up ER diagrams).
This isn't CakePHP specific, but you can modify the options so that the foreign keys and join tables follow the conventions that CakePHP uses. This would simplify your data modeling process once you've put the rules in place.
REST is an architecture, SOAP is a protocol.
That's the first problem.
You can send SOAP envelopes in a REST application.
SOAP itself is actually pretty basic and simple, it's the WSS-* standards on top of it that make it very complex.
If your consumers are other applications and other servers, there's a lot of support for the SOAP protocol today, and the basics of moving data is essentially a mouse-click in modern IDEs.
If your consumers are more likely to be RIAs or Ajax clients, you will probably want something simpler than SOAP, and more native to the client (notably JSON).
JSON packets sent over HTTP is not necessarily a REST architecture, it's just messages to URLs. All perfectly workable, but there are key components to the REST idiom. It is easy to confuse the two however. But just because you're talking HTTP requests does not necessarily mean you have a REST architecture. You can have a REST application with no HTTP at all (mind, this is rare).
So, if you have servers and consumers that are "comfortable" with SOAP, SOAP and WSS stack can serve you well. If you're doing more ad hoc things and want to better interface with web browsers, then some lighter protocol over HTTP can work well also.
Use the system stored procedure sp_who2

Below is a suggested approach to Question #1 which I use if I wish to use the ForEach-Object cmdlet. It does not directly answer the question because it does not EXIT the pipeline. However, it may achieve the desired effect in Q#1. The only drawback an amateur like myself can see is when processing large pipeline iterations.
$zStop = $false
(97..122) | Where-Object {$zStop -eq $false} | ForEach-Object {
$zNumeric = $_
$zAlpha = [char]$zNumeric
Write-Host -ForegroundColor Yellow ("{0,4} = {1}" -f ($zNumeric, $zAlpha))
if ($zAlpha -eq "m") {$zStop = $true}
}
Write-Host -ForegroundColor Green "My PSVersion = 5.1.18362.145"
I hope this is of use. Happy New Year to all.
Andy gave me some good pointers, but I wanted to do it in an even cleaner way. Not to mention that with the 2>&1 >>
method PowerShell complained to me about the log file being accessed by another process, i.e. both stderr and stdout trying to lock the file for access, I guess. So here's how I worked it around.
First let's generate a nice filename, but that's really just for being pedantic:
$name = "sync_common"
$currdate = get-date -f yyyy-MM-dd
$logfile = "c:\scripts\$name\log\$name-$currdate.txt"
And here's where the trick begins:
start-transcript -append -path $logfile
write-output "starting sync"
robocopy /mir /copyall S:\common \\10.0.0.2\common 2>&1 | Write-Output
some_other.exe /exeparams 2>&1 | Write-Output
...
write-output "ending sync"
stop-transcript
With start-transcript
and stop-transcript
you can redirect ALL output of PowerShell commands to a single file, but it doesn't work correctly with external commands. So let's just redirect all the output of those to the stdout of PS and let transcript do the rest.
In fact, I have no idea why the MS engineers say they haven't fixed this yet "due to the high cost and technical complexities involved" when it can be worked around in such a simple way.
Either way, running every single command with start-process
is a huge clutter IMHO, but with this method, all you gotta do is append the 2>&1 | Write-Output
code to each line which runs external commands.
Alternatively, if you are not concerned with the possible exception raised, you could change TryParse for Parse:
DateTime? d = DateTime.Parse("some valid text");
Although there won't be a boolean indicating success either, it could be practical in some situations where you know that the input text will always be valid.
I've seen occasional problems with Eclipse forgetting that built-in classes (including Object
and String
) exist. The way I've resolved them is to:
This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.
Kotlin code that works for me:
private fun takePhotoFromCamera() {
val intent = Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE)
startActivityForResult(intent, PERMISSIONS_REQUEST_TAKE_PICTURE_CAMERA)
}
And get Result :
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == PERMISSIONS_REQUEST_TAKE_PICTURE_CAMERA) {
if (resultCode == Activity.RESULT_OK) {
val photo: Bitmap? = MediaStore.Images.Media.getBitmap(this.contentResolver, Uri.parse( data!!.dataString) )
// Do something here : set image to an ImageView or save it ..
imgV_pic.imageBitmap = photo
} else if (resultCode == Activity.RESULT_CANCELED) {
Log.i(TAG, "Camera , RESULT_CANCELED ")
}
}
}
and don't forget to declare request code:
companion object {
const val PERMISSIONS_REQUEST_TAKE_PICTURE_CAMERA = 300
}
I usually use set_time_limit(30) within the main loop (so each loop iteration is limited to 30 seconds rather than the whole script).
I do this in multiple database update scripts, which routinely take several minutes to complete but less than a second for each iteration - keeping the 30 second limit means the script won't get stuck in an infinite loop if I am stupid enough to create one.
I must admit that my choice of 30 seconds for the limit is somewhat arbitrary - my scripts could actually get away with 2 seconds instead, but I feel more comfortable with 30 seconds given the actual application - of course you could use whatever value you feel is suitable.
Hope this helps!
Setting a reference to the Microsoft Access 12.0 Object Library allows us to test if a table exists using DCount.
Public Function ifTableExists(tblName As String) As Boolean
If DCount("[Name]", "MSysObjects", "[Name] = '" & tblName & "'") = 1 Then
ifTableExists = True
End If
End Function
You can also "fix" this by replacing the image with its inline Base64 representation:
Useful, when you do not intend to publish the page on the web, but instead use it on local machines only. img.src= "data:image/gif;base64,R0lGODlhCwALAIAAAAAA3pn/ZiH5BAEAAAEALAAAAAALAAsAAAIUhA+hkcuO4lmNVindo7qyrIXiGBYAOw==";
Best way is,
SELECT to_number(replace(:Str,',','')/100) --into num2

Contains(s2) is many times (in my computer 10 times) faster than IndexOf(s2) because Contains uses StringComparison.Ordinal that is faster than the culture sensitive search that IndexOf does by default (but that may change in .net 4.0 http://davesbox.com/archive/2008/11/12/breaking-changes-to-the-string-class.aspx).
Contains has exactly the same performance as IndexOf(s2,StringComparison.Ordinal) >= 0 in my tests but it's shorter and makes your intent clear.
This works for me, without 00, 001, 0011 etc prefix though:
/^\+*(\d{3})*[0-9,\-]{8,}/
I faced the same problem but on Ubuntu Server. So all I did is changed to superuser before I activate virtual environment for django and then I ran the django server. It worked fine for me.
First copy paste
sudo su
Then activate the virtual environment if you have one.
source myvenv/bin/activate
At last run your django server.
python3 manage.py runserver
Hope, this will help you.

Solution to flatten properties and arrays as well.
Example input:
{
obj1: {
prop1: "value1",
prop2: "value2"
},
arr1: [
"value1",
"value2"
]
}
Output:
"arr1[0]": "value1"
"arr1[1]": "value2"
"obj1.prop1": "value1"
"obj1.prop2": "value2"
Source code:
flatten(object, path = '', res = undefined) {
if (!Array.isArray(res)) {
res = [];
}
if (object !== null && typeof object === 'object') {
if (Array.isArray(object)) {
for (let i = 0; i < object.length; i++) {
this.flatten(object[i], path + '[' + i + ']', res)
}
} else {
const keys = Object.keys(object)
for (let i = 0; i < keys.length; i++) {
const key = keys[i]
this.flatten(object[key], path ? path + '.' + key : key, res)
}
}
} else {
if (path) {
res[path] = object
}
}
return res
}
Starting with Requests version 2.4.2, you can use the json=
parameter (which takes a dictionary) instead of data=
(which takes a string) in the call:
>>> import requests
>>> r = requests.post('http://httpbin.org/post', json={"key": "value"})
>>> r.status_code
200
>>> r.json()
{'args': {},
'data': '{"key": "value"}',
'files': {},
'form': {},
'headers': {'Accept': '*/*',
'Accept-Encoding': 'gzip, deflate',
'Connection': 'close',
'Content-Length': '16',
'Content-Type': 'application/json',
'Host': 'httpbin.org',
'User-Agent': 'python-requests/2.4.3 CPython/3.4.0',
'X-Request-Id': 'xx-xx-xx'},
'json': {'key': 'value'},
'origin': 'x.x.x.x',
'url': 'http://httpbin.org/post'}
It's used for proxying requests to other servers.
An example from http://wiki.nginx.org/LoadBalanceExample is:
http {
upstream myproject {
server 127.0.0.1:8000 weight=3;
server 127.0.0.1:8001;
server 127.0.0.1:8002;
server 127.0.0.1:8003;
}
server {
listen 80;
server_name www.domain.com;
location / {
proxy_pass http://myproject;
}
}
}
This means all requests for / go to the any of the servers listed under upstream XXX, with a preference for port 8000.
As of September 2016 this addon is the best to disable CORS: https://github.com/fredericlb/Force-CORS/releases
In the options panel you can configure which header to inject and specific website to have it enabled automatically.
Mainly, you've got 2 major problems:
You are using adding a List
of String
s. You want a List
containing List
s of Strings
.
Note as well that when you invoke this:
NodeList.addAll(nodes);
... all you say is to add all elements of nodes (which is a list of Strings) to the (badly named) NodeList
, which is using Objects and thus adds only the strings inside. Which leads me to the next point.
You seem to be confused between your nodes
and NodeList
. Your NodeList
keeps growing over time, and that's what you add to your list.
So, even if doing things right, if we were to look at the end of each iteration at your nodes
, nodeList
and list
, we'd see:
i = 0
nodes: [PropertyStart,a,b,c,PropertyEnd]
nodeList: [PropertyStart,a,b,c,PropertyEnd]
list: [[PropertyStart,a,b,c,PropertyEnd]]
i = 1
nodes: [PropertyStart,d,e,f,PropertyEnd]
nodeList: [PropertyStart,a,b,c,PropertyEnd, PropertyStart,d,e,f,PropertyEnd]
list: [[PropertyStart,a,b,c,PropertyEnd],[PropertyStart,a,b,c,PropertyEnd, PropertyStart,d,e,f,PropertyEnd]]
i = 2
nodes: [PropertyStart,g,h,i,PropertyEnd]
nodeList: [PropertyStart,a,b,c,PropertyEnd,PropertyStart,d,e,f,PropertyEnd,PropertyStart,g,h,i,PropertyEnd]
list: [[PropertyStart,a,b,c,PropertyEnd],[PropertyStart,a,b,c,PropertyEnd, PropertyStart,d,e,f,PropertyEnd],[PropertyStart,a,b,c,PropertyEnd,PropertyStart,d,e,f,PropertyEnd,PropertyStart,g,h,i,PropertyEnd]]
and so on...
Don't use variable names starting with uppercase letters. So here, replace NodeList
with nodeList
).
You say "I want the "list" array [...]". This is confusing for whoever you will be communicating with: It's not an array. It's an implementation of List
backed by an array.
There's a difference between a type, an interface, and an implementation.
Use generic types, because static typing really helps with these errors. Also, use interfaces where possible, except if you have a good reason to use the concrete type.
So your code becomes:
List<String> nodes = new ArrayList<String>();
List<String> nodeList = new ArrayList<String>();
List<List<String>> list = new ArrayList<List<String>>();
You could do away with the nodeList
entirely, and write the following once you've fixed your types:
list.add(nodes);
Except if you have a very strong reason to do so, prefer to use the inner-most scope to declare variables and limit both their lifespan for their references and facilitate the separation of concerns in your code.
Here you could then move List<String> nodes
to be declared within the loop (and then forget the nodes.clear()
invocation).
A reason not to do this could be performance, as you might want to avoid recreating an ArrayList
on each iteration of the loop, but it's very unlikely that's a concern to you (and clean, readable and maintainable code has priority over pre-optimized code).
Last but not least, if you want help give us the exact reproducible case with a short, self-Contained, correct example.
Here you give us your program's outputs, but don't mention how you got them, so we're left to assume you did a System.out.println(list)
. And you confused a lot of people, as I think the output you give us is not what you actually got.
With Java 8 it is a bit easier:
OptionalDouble average = marks
.stream()
.mapToDouble(a -> a)
.average();
Thus your average value is average.getAsDouble()
return average.isPresent() ? average.getAsDouble() : 0;
I like the Except extension methods, but the original question doesn't have symmetric key access and I prefer Contains (or the Any variation) to join, so with all credit to azuneca's answer:
public static IEnumerable<T> Except<T, TKey>(this IEnumerable<TKey> items,
IEnumerable<T> other, Func<T, TKey> getKey) {
return from item in items
where !other.Contains(getKey(item))
select item;
}
Which can then be used like:
var filteredApps = unfilteredApps.Except(excludedAppIds, ua => ua.Id);
Also, this version allows for needing a mapping for the exception IEnumerable by using a Select:
var filteredApps = unfilteredApps.Except(excludedApps.Select(a => a.Id), ua => ua.Id);
export class ClassComponent implements OnInit {
classes = [
{
name: 'string',
level: 'string',
code: 'number',
currentLesson: '1'
}]
checkCurrentLession(current){
this.classes.forEach((obj)=>{
if(obj.currentLession == current){
return true;
}
});
return false;
}
<ul class="table lessonOverview">
<li>
<p>Lesson 1</p>
<button [routerLink]="['/lesson1']"
[disabled]="checkCurrentLession(1)" class="primair">

</li>
<li>
<p>Lesson 2</p>
<button [routerLink]="['/lesson2']"
[disabled]="!checkCurrentLession(2)" class="primair">

</li>
</ul>
The problem is not in your Spring annotations but your design pattern. You mix together different scopes and threads:
The singleton is available anywhere, it is ok. However session/request scope is not available outside a thread that is attached to a request.
Asynchronous job can run even the request or session doesn't exist anymore, so it is not possible to use a request/session dependent bean. Also there is no way to know, if your are running a job in a separate thread, which thread is the originator request (it means aop:proxy is not helpful in this case).
I think your code looks like that you want to make a contract between ReportController, ReportBuilder, UselessTask and ReportPage. Is there a way to use just a simple class (POJO) to store data from UselessTask and read it in ReportController or ReportPage and do not use ReportBuilder anymore?
import datetime
date_str = '08/01/2018'
format_str = '%d/%m/%Y'
datetime_obj = datetime.datetime.strptime(date_str, format_str)
datetime_obj.replace(month=datetime_obj.month-1)
Simple solution, no need for special libraries.
Sometimes you need to call the base class' implementation, when you aren't in the derived function...It still works:
struct Base
{
virtual int Foo()
{
return -1;
}
};
struct Derived : public Base
{
virtual int Foo()
{
return -2;
}
};
int main(int argc, char* argv[])
{
Base *x = new Derived;
ASSERT(-2 == x->Foo());
//syntax is trippy but it works
ASSERT(-1 == x->Base::Foo());
return 0;
}
I tried a few of the answers on this page, but a lot of them didn't work for me. Maybe because I'm using Vim on Windows 7 (don't mock, just have pity on me :p)?
Here's the easiest one that I found that works on Vim in Windows 7:
:v/\S/d
Here's a longer answer on the Vim Wikia: http://vim.wikia.com/wiki/Remove_unwanted_empty_lines
As of Spring 4.2.x, you can create custom mapping annotations, using @RequestMapping
as a meta-annotation. So:
Is there a way to produce a "composite/inherited/aggregated" annotation with default values for consumes and produces, such that I could instead write something like:
@JSONRequestMapping(value = "/foo", method = RequestMethod.POST)
Yes, there is such a way. You can create a meta annotation like following:
@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@RequestMapping(consumes = "application/json", produces = "application/json")
public @interface JsonRequestMapping {
@AliasFor(annotation = RequestMapping.class, attribute = "value")
String[] value() default {};
@AliasFor(annotation = RequestMapping.class, attribute = "method")
RequestMethod[] method() default {};
@AliasFor(annotation = RequestMapping.class, attribute = "params")
String[] params() default {};
@AliasFor(annotation = RequestMapping.class, attribute = "headers")
String[] headers() default {};
@AliasFor(annotation = RequestMapping.class, attribute = "consumes")
String[] consumes() default {};
@AliasFor(annotation = RequestMapping.class, attribute = "produces")
String[] produces() default {};
}
Then you can use the default settings or even override them as you want:
@JsonRequestMapping(method = POST)
public String defaultSettings() {
return "Default settings";
}
@JsonRequestMapping(value = "/override", method = PUT, produces = "text/plain")
public String overrideSome(@RequestBody String json) {
return json;
}
You can read more about AliasFor
in spring's javadoc and github wiki.
I use a small set of documentation patterns:
This XML file does not appear to have any style information associated with it. The document tree is shown below.
You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml
instead of text/html
and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.
In case of JSF/Facelets files which have the default extension of .xhtml
, that can in turn happen if the HTTP request hasn't invoked the FacesServlet
and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml
file extension which is in your Firefox configuration apparently by default interpreted as text/xml
.
You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern>
of the FacesServlet
as registered in webapp's web.xml
, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf
, then you need to open the page by /some.jsf
instead of /some.xhtml
. Alternatively, you can also just change the <url-pattern>
to *.xhtml
. This way you never need to fiddle with virtual URLs.
Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.
I'm the developer of Redux Auth and some of the issues you mentioned have been fixed in the version 2 beta. You can download this off the offcial website with a sample application too.
- Requires autoloading (impeding performance)
- Uses the inherently unsafe concept of 'security questions'. Dealbreaker!
Security questions are now not used and a simpler forgotten password system has been put in place.
- Return types are a bit of a hodgepodge of true, false, error and success codes
This was fixed in version 2 and returns boolean values. I hated the hodgepodge as much as you.
- Doesn't hook into CI's validation system
The sample application uses the CI's validation system.
- Doesn't allow a user to resend a 'lost password' code
Work in progress
I also implemented some other features such as email views, this gives you the choice of being able to use the CodeIgniter helpers in your emails.
It's still a work in progress so if have any more suggestions please keep them coming.

Ps : Thanks for recommending Redux.

Found this gem from our friends over at SitePoint. https://www.sitepoint.com/url-parameters-jquery/.
Using PURE jQuery. I just used this and it worked. Tweaked it a bit for example sake.
//URL is http://www.example.com/mypage?ref=registration&[email protected]
$.urlParam = function (name) {
var results = new RegExp('[\?&]' + name + '=([^&#]*)')
.exec(window.location.search);
return (results !== null) ? results[1] || 0 : false;
}
console.log($.urlParam('ref')); //registration
console.log($.urlParam('email')); //[email protected]
Use as you will.

'First check if the last row is empty; if not, add a row

Set lastRow = table.ListRows(table.ListRows.Count).Range
If Application.CountBlank(lastRow) < lastRow.Columns.Count Then
table.ListRows.Add
End If
End If
'Iterate through the last row and populate it with the entries from values()
Set lastRow = table.ListRows(table.ListRows.Count).Range

[ ].has(obj)
assuming .indexOf()
is implemented
Object.defineProperty( Array.prototype,'has',
{
value:function(o, flag){
if (flag === undefined) {
return this.indexOf(o) !== -1;
} else { // only for raw js object
for(var v in this) {
if( JSON.stringify(this[v]) === JSON.stringify(o)) return true;
}
return false;
},
// writable:false,
// enumerable:false
})
!!! do not make Array.prototype.has=function(){...
because you'll add an enumerable element in every array and js is broken.
//use like
[22 ,'a', {prop:'x'}].has(12) // false
["a","b"].has("a") // true
[1,{a:1}].has({a:1},1) // true
[1,{a:1}].has({a:1}) // false
the use of 2nd arg (flag) forces comparation by value instead of reference
comparing raw objects
[o1].has(o2,true) // true if every level value is same
For ASP.NET Core You can use asp-route-* attribute:
<form asp-action="Login" asp-route-previous="@Model.ReturnUrl">
An example: Imagine that you have a Vehicle Controller with actions
Index
Details
Edit
and you can edit any vehicle from Index or from Details, so if you clicked edit from index you must return to index after edit and if you clicked edit from details you must return to details after edit.
//In your viewmodel add the ReturnUrl Property
public class VehicleViewModel
{
..............
..............
public string ReturnUrl {get;set;}
}
Details.cshtml
<a asp-action="Edit" asp-route-previous="Details" asp-route-id="@Model.CarId">Edit</a>
Index.cshtml
<a asp-action="Edit" asp-route-previous="Index" asp-route-id="@item.CarId">Edit</a>
Edit.cshtml
<form asp-action="Edit" asp-route-previous="@Model.ReturnUrl" class="form-horizontal">
<div class="box-footer">
<a asp-action="@Model.ReturnUrl" class="btn btn-default">Back to List</a>
<button type="submit" value="Save" class="btn btn-warning pull-right">Save</button>
</div>
</form>
In your controller:
// GET: Vehicle/Edit/5
public ActionResult Edit(int id,string previous)
{
var model = this.UnitOfWork.CarsRepository.GetAllByCarId(id).FirstOrDefault();
var viewModel = this.Mapper.Map<VehicleViewModel>(model);//if you using automapper
//or by this code if you are not use automapper
var viewModel = new VehicleViewModel();
if (!string.IsNullOrWhiteSpace(previous)
viewModel.ReturnUrl = previous;
else
viewModel.ReturnUrl = "Index";
return View(viewModel);
}
[HttpPost]
public IActionResult Edit(VehicleViewModel model, string previous)
{
if (!string.IsNullOrWhiteSpace(previous))
model.ReturnUrl = previous;
else
model.ReturnUrl = "Index";
.............
.............
return RedirectToAction(model.ReturnUrl);
}
This statement works for me
ALTER TABLE table_name DROP UNIQUE (column_name);
In C, except for a few special cases, an array reference always "decays" to a pointer to the first element of the array. Therefore, it isn't possible to pass an array "by value". An array in a function call will be passed to the function as a pointer, which is analogous to passing the array by reference.
EDIT: There are three such special cases where an array does not decay to a pointer to it's first element:
sizeof a
is not the same as sizeof (&a[0])
.&a
is not the same as &(&a[0])
(and not quite the same as &a[0]
).char b[] = "foo"
is not the same as char b[] = &("foo")

It's a really bad idea to use *
, which leaves you wide open to cross site scripting. You basically want your own domain all of the time, scoped to your current SSL settings, and optionally additional domains. You also want them all to be sent as one header. The following will always authorize your own domain in the same SSL scope as the current page, and can optionally also include any number of additional domains. It will send them all as one header, and overwrite the previous one(s) if something else already sent them to avoid any chance of the browser grumbling about multiple access control headers being sent.
class CorsAccessControl
{
private $allowed = array();
/**
* Always adds your own domain with the current ssl settings.
*/
public function __construct()
{
// Add your own domain, with respect to the current SSL settings.
$this->allowed[] = 'http'
. ( ( array_key_exists( 'HTTPS', $_SERVER )
&& $_SERVER['HTTPS']
&& strtolower( $_SERVER['HTTPS'] ) !== 'off' )
? 's'
: null )
. '://' . $_SERVER['HTTP_HOST'];
}
/**
* Optionally add additional domains. Each is only added one time.
*/
public function add($domain)
{
if ( !in_array( $domain, $this->allowed )
{
$this->allowed[] = $domain;
}
/**
* Send 'em all as one header so no browsers grumble about it.
*/
public function send()
{
$domains = implode( ', ', $this->allowed );
header( 'Access-Control-Allow-Origin: ' . $domains, true ); // We want to send them all as one shot, so replace should be true here.
}
}
Usage:
$cors = new CorsAccessControl();
// If you are only authorizing your own domain:
$cors->send();
// If you are authorizing multiple domains:
foreach ($domains as $domain)
{
$cors->add($domain);
}
$cors->send();
You get the idea.
DataContractJsonSerializer serializer =
new DataContractJsonSerializer(typeof(YourObjectType));
YourObjectType yourObject = (YourObjectType)serializer.ReadObject(jsonStream);
You could also use the JavaScriptSerializer
, but DataContractJsonSerializer
is supposedly better able to handle complex types.
Oddly enough JavaScriptSerializer was once deprecated (in 3.5) and then resurrected because of ASP.NET MVC (in 3.5 SP1). That would definitely be enough to shake my confidence and lead me to use DataContractJsonSerializer
since it is hard baked for WCF.

The following demo page (also available on gist, more technical details there) will prompt user to scroll, which then triggers a soft-fullscreen (hide address bar/menu), where header and content fills the new viewport.

Some notes to complement the ALTER DATABASE process:
1) You can obtain a full list of databases with logical names and full paths of MDF and LDF files:
USE master SELECT name, physical_name FROM sys.master_files
2) You can move manually the files with CMD move command:
Move "Source" "Destination"
Example:
md "D:\MSSQLData"
Move "C:\test\SYSADMIT-DB.mdf" "D:\MSSQLData\SYSADMIT-DB_Data.mdf"
Move "C:\test\SYSADMIT-DB_log.ldf" "D:\MSSQLData\SYSADMIT-DB_log.ldf"
3) You should change the default database path for new databases creation. The default path is obtained from the Windows registry.
You can also change with T-SQL, for example, to set default destination to: D:\MSSQLData
USE [master]
GO
EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultData', REG_SZ, N'D:\MSSQLData'

As a side note, the reason revoke usage on *.* from 'phpmyadmin'@'localhost';
does not work is quite simple : There is no grant called USAGE
.
The actual named grants are in the MySQL Documentation
The grant USAGE
is a logical grant. How? 'phpmyadmin'@'localhost' has an entry in mysql.user
where user='phpmyadmin' and host='localhost'. Any row in mysql.user semantically means USAGE
. Running DROP USER 'phpmyadmin'@'localhost';
should work just fine. Under the hood, it's really doing this:
DELETE FROM mysql.user WHERE user='phpmyadmin' and host='localhost';
DELETE FROM mysql.db WHERE user='phpmyadmin' and host='localhost';
FLUSH PRIVILEGES;
Therefore, the removal of a row from mysql.user
constitutes running REVOKE USAGE
, even though REVOKE USAGE
cannot literally be executed.
It means that the variable it is a prefix to is available to be used within a block.
You'll need some sort of uniquely identifying column in your table, like an auto-filling primary key or a datetime column (preferably the primary key). Then you can do this:
SELECT * FROM table_name ORDER BY unique_column DESC LIMIT 1
The ORDER BY column
tells it to rearange the results according to that column's data, and the DESC
tells it to reverse the results (thus putting the last one first). After that, the LIMIT 1
tells it to only pass back one row.
Not sure what your asking!
However
SELECT GETDATE()
Will get you the current date and time
SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))
Will get you just the date with time set to 00:00:00
In Java, all strings are immutable. When you are trying to modify a String
, what you are really doing is creating a new one. However, when you use a StringBuilder
, you are actually modifying the contents, instead of creating a new one.
The shortest way to sum it up is that an interface
is:
default
and static
methods; while it has definitions (method signatures + implementations) for default
and static
methods, it only has declarations (method signatures) for other methods.interface
s, and an interface
can inherit from multiple interface
s). All variables are implicitly constant, whether specified as public static final
or not. All members are implicitly public
, whether specified as such or not.Meanwhile, an abstract
class is:
abstract
methods. Can contain both declarations and definitions, with declarations marked as abstract
.protected
, private
, or private package (unspecified).Or, if we want to boil it all down to a single sentence: An interface
is what the implementing class has, but an abstract
class is what the subclass is.
The CSS box model is rather complicated, particularly when it comes to scrolling content. While the browser uses the values from your CSS to draw boxes, determining all the dimensions using JS is not straight-forward if you only have the CSS.
That's why each element has six DOM properties for your convenience: offsetWidth
, offsetHeight
, clientWidth
, clientHeight
, scrollWidth
and scrollHeight
. These are read-only attributes representing the current visual layout, and all of them are integers (thus possibly subject to rounding errors).
Let's go through them in detail:
offsetWidth
, offsetHeight
: The size of the visual box incuding all borders. Can be calculated by adding width
/height
and paddings and borders, if the element has display: block
clientWidth
, clientHeight
: The visual portion of the box content, not including borders or scroll bars , but includes padding . Can not be calculated directly from CSS, depends on the system's scroll bar size.scrollWidth
, scrollHeight
: The size of all of the box's content, including the parts that are currently hidden outside the scrolling area. Can not be calculated directly from CSS, depends on the content.Since offsetWidth
takes the scroll bar width into account, we can use it to calculate the scroll bar width via the formula
scrollbarWidth = offsetWidth - clientWidth - getComputedStyle().borderLeftWidth - getComputedStyle().borderRightWidth
Unfortunately, we may get rounding errors, since offsetWidth
and clientWidth
are always integers, while the actual sizes may be fractional with zoom levels other than 1.
Note that this
scrollbarWidth = getComputedStyle().width + getComputedStyle().paddingLeft + getComputedStyle().paddingRight - clientWidth
does not work reliably in Chrome, since Chrome returns width
with scrollbar already substracted. (Also, Chrome renders paddingBottom to the bottom of the scroll content, while other browsers don't)
There are not many good reasons this would fail, especially the regsvr32 step. Run dumpbin /exports on that dll. If you don't see DllRegisterServer then you've got a corrupt install. It should have more side-effects, you wouldn't be able to build C/C++ projects anymore.
One standard failure mode is running this on a 64-bit operating system. This is 32-bit unmanaged code, you would indeed get the 'class not registered' exception. Project + Properties, Build tab, change Platform Target to x86.
"Incorrect padding" can mean not only "missing padding" but also (believe it or not) "incorrect padding".
If suggested "adding padding" methods don't work, try removing some trailing bytes:
lens = len(strg)
lenx = lens - (lens % 4 if lens % 4 else 4)
try:
result = base64.decodestring(strg[:lenx])
except etc
Update: Any fiddling around adding padding or removing possibly bad bytes from the end should be done AFTER removing any whitespace, otherwise length calculations will be upset.
It would be a good idea if you showed us a (short) sample of the data that you need to recover. Edit your question and copy/paste the result of print repr(sample)
.
Update 2: It is possible that the encoding has been done in an url-safe manner. If this is the case, you will be able to see minus and underscore characters in your data, and you should be able to decode it by using base64.b64decode(strg, '-_')
If you can't see minus and underscore characters in your data, but can see plus and slash characters, then you have some other problem, and may need the add-padding or remove-cruft tricks.
If you can see none of minus, underscore, plus and slash in your data, then you need to determine the two alternate characters; they'll be the ones that aren't in [A-Za-z0-9]. Then you'll need to experiment to see which order they need to be used in the 2nd arg of base64.b64decode()
Update 3: If your data is "company confidential":
(a) you should say so up front
(b) we can explore other avenues in understanding the problem, which is highly likely to be related to what characters are used instead of +
and /
in the encoding alphabet, or by other formatting or extraneous characters.
One such avenue would be to examine what non-"standard" characters are in your data, e.g.
from collections import defaultdict
d = defaultdict(int)
import string
s = set(string.ascii_letters + string.digits)
for c in your_data:
if c not in s:
d[c] += 1
print d
As user1511510 has identified, there's an unusual case when abc is at the end of the file name. We need to look for either /abc/
or /abc
followed by a string-terminator '\0'
. A naive way to do this would be to check if either /abc/
or /abc\0
are substrings:
#include <stdio.h>
#include <string.h>
int main() {
const char *str = "/user/desktop/abc";
const int exists = strstr(str, "/abc/") || strstr(str, "/abc\0");
printf("%d\n",exists);
return 0;
}
but exists
will be 1 even if abc is not followed by a null-terminator. This is because the string literal "/abc\0"
is equivalent to "/abc"
. A better approach is to test if /abc
is a substring, and then see if the character after this substring (indexed using the pointer returned by strstr()
) is either a /
or a '\0'
:
#include <stdio.h>
#include <string.h>
int main() {
const char *str = "/user/desktop/abc", *substr;
const int exists = (substr = strstr(str, "/abc")) && (substr[4] == '\0' || substr[4] == '/');
printf("%d\n",exists);
return 0;
}
This should work in all cases.
This may help somebody in future that's why adding this answer.
In my Case for android studio project. I have to enable Places API as well to get suggestions
This works for me.
It will be something like this:
SELECT b.Title, b.Edition, b.Year, b.Pages, b.Rating, c.Category, p.Publisher, w.LastName
FROM
Books b
JOIN Categories_Book cb ON cb._ISBN = b._Books_ISBN
JOIN Category c ON c._CategoryID = cb._Categories_Category_ID
JOIN Publishers p ON p._PublisherID = b.PublisherID
JOIN Writers_Books wb ON wb._Books_ISBN = b._ISBN
JOIN Writer w ON w._WritersID = wb._Writers_WriterID
You use the join
statement to indicate which fields from table A map to table B. I'm using aliases here thats why you see Books b
the Books
table will be referred to as b
in the rest of the query. This makes for less typing.
FYI your naming convention is very strange, I would expect it to be more like this:
Book: ID, ISBN , BookTitle, Edition, Year, PublisherID, Pages, Rating
Category: ID, [Name]
BookCategory: ID, CategoryID, BookID
Publisher: ID, [Name]
Writer: ID, LastName
BookWriter: ID, WriterID, BookID
Try the following code:
function getStackTrace(){
var f = arguments.callee;
var ret = [];
var item = {};
var iter = 0;
while ( f = f.caller ){
// Initialize
item = {
name: f.name || null,
args: [], // Empty array = no arguments passed
callback: f
};
// Function arguments
if ( f.arguments ){
for ( iter = 0; iter<f.arguments.length; iter++ ){
item.args[iter] = f.arguments[iter];
}
} else {
item.args = null; // null = argument listing not supported
}
ret.push( item );
}
return ret;
}
Worked for me in Firefox-21 and Chromium-25.
Only static functions are called with class name.
classname::Staicfunction();
Non static functions have to be called using objects.
classname obj;
obj.Somefunction();
This is exactly what your error means. Since your function is non static you have to use a object reference to invoke it.
Spark 1.6+
sc.getConf.getAll.foreach(println)
Here is another solution you could have used. It is working in my app.
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
android.support.v7.app.ActionBar actionBar =getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
setContentView(R.layout.activity_main)
Then you can get rid of that import for the one line ActionBar use.
function page_title($val){
include(dirname(__FILE__).'/simple_html_dom.php');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$val);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:25.0) Gecko/20100101 Firefox/25.0');
curl_setopt($ch, CURLOPT_ENCODING , "gzip");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
$return = curl_exec($ch);
$encot = false;
$charset = curl_getinfo($ch, CURLINFO_CONTENT_TYPE);
curl_close($ch);
$html = str_get_html('"'.$return.'"');
if(strpos($charset,'charset=') !== false) {
$c = str_replace("text/html; charset=","",$charset);
$encot = true;
}
else {
$lookat=$html->find('meta[http-equiv=Content-Type]',0);
$chrst = $lookat->content;
preg_match('/charset=(.+)/', $chrst, $found);
$p = trim($found[1]);
if(!empty($p) && $p != "")
{
$c = $p;
$encot = true;
}
}
$title = $html->find('title')[0]->innertext;
if($encot == true && $c != 'utf-8' && $c != 'UTF-8') $title = mb_convert_encoding($title,'UTF-8',$c);
return $title;
}
You can use .NET 4's dynamic type and built-in JavaScriptSerializer to do that. Something like this, maybe:
string json = "{\"items\":[{\"Name\":\"AAA\",\"Age\":\"22\",\"Job\":\"PPP\"},{\"Name\":\"BBB\",\"Age\":\"25\",\"Job\":\"QQQ\"},{\"Name\":\"CCC\",\"Age\":\"38\",\"Job\":\"RRR\"}]}";
var jss = new JavaScriptSerializer();
dynamic data = jss.Deserialize<dynamic>(json);
StringBuilder sb = new StringBuilder();
sb.Append("<table>\n <thead>\n <tr>\n");
// Build the header based on the keys in the
// first data item.
foreach (string key in data["items"][0].Keys) {
sb.AppendFormat(" <th>{0}</th>\n", key);
}
sb.Append(" </tr>\n </thead>\n <tbody>\n");
foreach (Dictionary<string, object> item in data["items"]) {
sb.Append(" <tr>\n");
foreach (string val in item.Values) {
sb.AppendFormat(" <td>{0}</td>\n", val);
}
}
sb.Append(" </tr>\n </tbody>\n</table>");
string myTable = sb.ToString();
At the end, myTable
will hold a string that looks like this:
<table>
<thead>
<tr>
<th>Name</th>
<th>Age</th>
<th>Job</th>
</tr>
</thead>
<tbody>
<tr>
<td>AAA</td>
<td>22</td>
<td>PPP</td>
<tr>
<td>BBB</td>
<td>25</td>
<td>QQQ</td>
<tr>
<td>CCC</td>
<td>38</td>
<td>RRR</td>
</tr>
</tbody>
</table>
If you want to check the number of insertions, deletions & commits, between two branches or commits.
using commit id's:
git log <commit-id>..<commit-id> --numstat --pretty="%H" --author="<author-name>" | awk 'NF==3 {added+=$1; deleted+=$2} NF==1 {commit++} END {printf("total lines added: +%d\ntotal lines deleted: -%d\ntotal commits: %d\n", added, deleted, commit)}'
using branches:
git log <parent-branch>..<child-branch> --numstat --pretty="%H" --author="<author-name>" | awk 'NF==3 {added+=$1; deleted+=$2} NF==1 {commit++} END {printf("total lines added: +%d\ntotal lines deleted: -%d\ntotal commits: %d\n", added, deleted, commit)}'
JavaScript only solution:
var tmpParams = decodeURIComponent(window.location.search.substr(1)).split("&");
for (var i = 0; i < tmpParams.length; i++) {
var tmparr = tmpParams[i].split("=");
var tmp = document.getElementsByName(tmparr[0])[0];
if (!!tmp){
document.getElementsByName(tmparr[0])[0].value = tmparr[1];
}
}
Or if you are using jQuery you can replace
var tmp = document.getElementsByName(tmparr[0])[0];
if (!!tmp){
document.getElementsByName(tmparr[0])[0].value = tmparr[1];
}
with:
$('*[name="'+tmparr[0]+'"]').val(tmparr[1]);
This JQuery Worked for me :-
$(document).ready(function() {
$('#con_image').on('mousedown', function(e) {
e.preventDefault();
});
});
GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH
. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:
export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH
Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).
The solution is the /Y
switch:
xcopy "C:\Users\ADMIN\Desktop\*.*" "D:\Backup\" /K /D /H /Y
This has been interesting to read. I have been pondering the same question myself, and the benefits of thinking about it are this:
Trying to imagine how to implement OOP concepts in a non-OOP language helps me understand the strengths of the OOp language (in my case, C++). This helps give me better judgement about whether to use C or C++ for a given type of application -- where the benefits of one out-weighs the other.
In my browsing the web for information and opinions on this I found an author who was writing code for an embedded processor and only had a C compiler available: http://www.eetimes.com/discussion/other/4024626/Object-Oriented-C-Creating-Foundation-Classes-Part-1
In his case, analyzing and adapting OOP concepts in plain C was a valid pursuit. It appears he was open to sacrificing some OOP concepts due to the performance overhead hit resulting from attempting to implement them in C.
The lesson I've taken is, yes it can be done to a certain degree, and yes, there are some good reasons to attempt it.
In the end, the machine is twiddling stack pointer bits, making the program counter jump around and calculating memory access operations. From the efficiency standpoint, the fewer of these calculations done by your program, the better... but sometimes we have to pay this tax simply so we can organize our program in a way that makes it least susceptible to human error. The OOP language compiler strives to optimize both aspects. The programmer has to be much more careful implementing these concepts in a language like C.
Like Robert K said, don't use jQuery.html().text() to decode html entities as it's unsafe because user input should never have access to the DOM. Read about XSS for why this is unsafe.
Instead try the Underscore.js utility-belt library which comes with escape and unescape methods:
Escapes a string for insertion into HTML, replacing &
, <
, >
, "
, `
, and '
characters.
_.escape('Curly, Larry & Moe');
=> "Curly, Larry & Moe"
The opposite of escape, replaces &
, <
, >
, "
, `
and '
with their unescaped counterparts.
_.unescape('Curly, Larry & Moe');
=> "Curly, Larry & Moe"
To support decoding more characters, just copy the Underscore unescape method and add more characters to the map.
It's not "plumbing", but it'll do exactly what you want:
$ git log --format=%B -n 1 <commit>
If you absolutely need a "plumbing" command (not sure why that's a requirement), you can use rev-list
:
$ git rev-list --format=%B --max-count=1 <commit>
Although rev-list
will also print out the commit sha (on the first line) in addition to the commit message.
To find out if a string contains substring you can use the index
function:
if (index($str, $substr) != -1) {
print "$str contains $substr\n";
}
It will return the position of the first occurrence of $substr
in $str
, or -1 if the substring is not found.
As far as I know, currently (Android Studio 2.3) there is no way to do this.
As per Android Studio documentation:
"Note: Only one debugger can be connected to your device at a time."
When you attempt to connect Android Device Monitor it disconnects Android Studio's debug session and vice versa, when you attempt to connect Android Studio's debugger, it disconnects Android Device Monitor.
Fortunately the new version of Android Studio (3.0) will feature a Device File Explorer that will allow you to pull files from within Android Studio without the need to open the Android Device Monitor which should resolve the problem.
Although I'm late to the party, this post is among the top results in the google search "generate load in linux".
The result marked as solution could be used to generate a system load, i'm preferring to use sha1sum /dev/zero
to impose a load on a cpu-core.
The idea is to calculate a hash sum from an infinite datastream (eg. /dev/zero, /dev/urandom, ...) this process will try to max out a cpu-core until the process is aborted. To generate a load for more cores, multiple commands can be piped together.
eg. generate a 2 core load:
sha1sum /dev/zero | sha1sum /dev/zero
You can style the button using CSS or use an image-input. Additionally you might use the button
element which supports inline content.
<button type="submit"><img src="/path/to/image" alt="Submit"></button>
This should do it:
WHERE `date` = CURDATE() - INTERVAL 1 DAY
In bootstrap 4 use:
<ul class="nav navbar-nav ml-auto">
This will push the navbar to the right. Use mr-auto to push it to the left, this is the default behaviour.
Just in case you are able to utilize a scripting language to prepare your SQL queries, you could reuse field=value pairs by using SET
instead of (a,b,c) VALUES(a,b,c)
.
An example with PHP:
$pairs = "a=$a,b=$b,c=$c";
$query = "INSERT INTO $table SET $pairs ON DUPLICATE KEY UPDATE $pairs";
Example table:
CREATE TABLE IF NOT EXISTS `tester` (
`a` int(11) NOT NULL,
`b` varchar(50) NOT NULL,
`c` text NOT NULL,
UNIQUE KEY `a` (`a`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
Views can:
And you should not design tables to match views. Your base model should concern itself with efficient storage and retrieval of the data. Views are partly a tool that mitigates the complexities that arise from an efficient, normalized model by allowing you to abstract that complexity.
Also, asking "what are the advantages of using a view over a table? " is not a great comparison. You can't go without tables, but you can do without views. They each exist for a very different reason. Tables are the concrete model and Views are an abstracted, well, View.
To represent a unicode string as a string of bytes is known as encoding. Use u'...'.encode(encoding)
.
Example:
>>> u'æøå'.encode('utf8') '\xc3\x83\xc2\xa6\xc3\x83\xc2\xb8\xc3\x83\xc2\xa5' >>> u'æøå'.encode('latin1') '\xc3\xa6\xc3\xb8\xc3\xa5' >>> u'æøå'.encode('ascii') UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-5: ordinal not in range(128)
You typically encode a unicode string whenever you need to use it for IO, for instance transfer it over the network, or save it to a disk file.
To convert a string of bytes to a unicode string is known as decoding. Use unicode('...', encoding)
or '...'.decode(encoding).
Example:
>>> u'æøå' u'\xc3\xa6\xc3\xb8\xc3\xa5' # the interpreter prints the unicode object like so >>> unicode('\xc3\xa6\xc3\xb8\xc3\xa5', 'latin1') u'\xc3\xa6\xc3\xb8\xc3\xa5' >>> '\xc3\xa6\xc3\xb8\xc3\xa5'.decode('latin1') u'\xc3\xa6\xc3\xb8\xc3\xa5'
You typically decode a string of bytes whenever you receive string data from the network or from a disk file.
I believe there are some changes in unicode handling in python 3, so the above is probably not correct for python 3.
Some good links:
You could do something like this:
$("span, p").each(function() {
var text = $(this).text();
text = text.replace("lollypops", "marshmellows");
$(this).text(text);
});
It will be better to mark all tags with text that needs to be examined with a suitable class name.
Also, this may have performance issues. jQuery or javascript in general aren't really suitable for this kind of operations. You are better off doing it server side.
optional : if you set config about php.ini but still can't upload
-this is php function to check error code
$error_type = [];
$error_type[0] = "There is no error";
$error_type[1] = "The uploaded file exceeds the upload_max_filesize directive in php.ini.";
$error_type[2] = "The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form.";
$error_type[3] = "The uploaded file was only partially uploaded.";
$error_type[4] = "No file was uploaded.";
//$error_type["5"] = "";
$error_type[6] = "Missing a temporary folder. Introduced in PHP 5.0.3.";
$error_type[7] = "Failed to write file to disk. Introduced in PHP 5.1.0.";
$error_type[8] = "A PHP extension stopped the file upload. PHP does not provide a way to ascertain which extension caused the file upload to stop; examining the list of loaded extensions with phpinfo() may help. Introduced in PHP 5.2.0.";
//------------------------------
//--> show msg error.
$status_code = $_FILES["uploadfile"]["error"];
if($status_code != 0){
echo $error_type[$status_code];
exit;
}
The simplest and efficient solution is :
pgrep -fl aa.sh
You can also use DBMS_METADATA:

I have tried everything until I realized a new cygwin toolchain has messed up python logic. cygwin install a compiler called "realgcc" that is not a real gcc.
Solution
Install gcc. Ex:
apt-cyg install gcc-g++
With JDK,
You can also use jinfo to connect to the JVM for the <PROCESS_ID>
in question and get the value for MaxHeapSize:
jinfo -flag MaxHeapSize <PROCESS_ID>
As many of the answer suggesting better solution is to use ArrayList. ArrayList size is not fixed and it is easily manageable.
It is resizable-array implementation of the List interface. Implements all optional list operations, and permits all elements, including null. In addition to implementing the List interface, this class provides methods to manipulate the size of the array that is used internally to store the list.
Each ArrayList instance has a capacity. The capacity is the size of the array used to store the elements in the list. It is always at least as large as the list size. As elements are added to an ArrayList, its capacity grows automatically.
Note that this implementation is not synchronized.
ArrayList<String> scripts = new ArrayList<String>();
scripts.add("test1");
scripts.add("test2");
scripts.add("test3");
UPDATE: for your updated question
variable.match(/\[[0-9]+\]/);
Try this:
variable.match(/[0-9]+/); // for unsigned integers
variable.match(/[-0-9]+/); // for signed integers
variable.match(/[-.0-9]+/); // for signed float numbers
Hope this helps!

$(':focus')[0]
will give you the actual element.
$(':focus')
will give you an array of elements, usually only one element is focused at a time so this is only better if you somehow have multiple elements focused.
I did not see any reference to Raphael.js. So I thought I'd include it here. Raphael.js is backwards compatible all the way back to IE5 and a very early Firefox as well as all of the rest of the browsers. It uses SVG when it can and VML when it can not. What you do with it is to draw onto a canvas. Some browsers will even let you select the text that is generated. Raphael.js can be found here:
It can be as simple as creating your paper drawing area, specifying the font, font-weight, size, etc... and then telling it to put your string of text onto the paper. I am not sure if it gets around the licensing issues or not but it is drawing the text so I'm fairly certain it does circumvent the licensing issues. But check with your lawyer to be sure. :-)
Lets look at this code (jdk1.8)
@Test
public void testArraySize() throws Exception {
List<String> list = new ArrayList<>();
list.add("ds");
list.add("cx");
list.add("cx");
list.add("ww");
list.add("ds");
list.add("cx");
list.add("cx");
list.add("ww");
list.add("ds");
list.add("cx");
list.add("last");
}
1)Put break point on the line when "last" is inserted
2)Go to the add method of ArrayList
You will see
ensureCapacityInternal(size + 1); // Increments modCount!!
elementData[size++] = e;
3) Go to ensureCapacityInternal method this method call ensureExplicitCapacity
4)
private void ensureExplicitCapacity(int minCapacity) {
modCount++;
// overflow-conscious code
if (minCapacity - elementData.length > 0)
grow(minCapacity);
}
return true;
In our example minCapacity is equal to 11 11-10 > 0
therefore You need grow
method
5)
private void grow(int minCapacity) {
// overflow-conscious code
int oldCapacity = elementData.length;
int newCapacity = oldCapacity + (oldCapacity >> 1);
if (newCapacity - minCapacity < 0)
newCapacity = minCapacity;
if (newCapacity - MAX_ARRAY_SIZE > 0)
newCapacity = hugeCapacity(minCapacity);
// minCapacity is usually close to size, so this is a win:
elementData = Arrays.copyOf(elementData, newCapacity);
}
Lets describe each step:
1) oldCapacity
= 10 because we didn't put this param when ArrayList
was init ,therefore it will use default capacity(10)
2) int newCapacity = oldCapacity + (oldCapacity >> 1);
Here newCapacity is equal to oldCapacity plus oldCapacity with right shift by one
(oldCapacity is 10
this is the binary representation 00001010
moving one bit to right we will get 00000101
which is 5 in decimal therefore newCapacity
is 10 + 5 = 15
)
3)
if (newCapacity - minCapacity < 0)
newCapacity = minCapacity;
For example your init capacity is 1, when you add the second element into arrayList newCapacity
will be equal to 1(oldCapacity) + 0 (moved to right by one bit) = 1
In this case newCapacity is less than minCapacity and elementData
(array object inside arrayList) can't hold new element therefore newCapacity is equal to minCapacity
4)
if (newCapacity - MAX_ARRAY_SIZE > 0)
newCapacity = hugeCapacity(minCapacity);
Check if array size reach MAX_ARRAY_SIZE (which is Integer.MAX - 8) Why the maximum array size of ArrayList is Integer.MAX_VALUE - 8?
5) Finally it copy old values to the newArray with length 15

You may find this useful but it is not exactly the same as GitHub's feature.
Use This method:
public static String getAndroidVersion() {
String versionName = "";
try {
versionName = String.valueOf(Build.VERSION.RELEASE);
} catch (Exception e) {
e.printStackTrace();
}
return versionName;
}
SELECT datetime(CURRENT_TIMESTAMP, 'localtime')
A little late to this party - but this also works well:
CREATE VIEW [ABC].[View_SomeDataUniqueKey]
AS
SELECT
CAST(CONCAT(CAST([ID] AS VARCHAR(4)),
CAST(ROW_NUMBER() OVER(ORDER BY [ID] ASC) as VARCHAR(4))
) AS int) AS [UniqueId]
,[ID]
FROM SOME_TABLE JOIN SOME_OTHER_TABLE
GO
In my case the join resulted in [ID] - the primary key being repeated up to 5 times (associated different unique data) The nice trick with this is that the original ID can be determined from each UniqueID effectively [ID]+RowNumber() = 11, 12, 13, 14, 21, 22, 23, 24 etc. If you add RowNumber() and [ID] back into the view - you can easily determine your original key from the data. But - this is not something that should be committed to a table because I am fairly sure that the RowNumber() of a view will never be reliably the same as the underlying data alters, even with the OVER(ORDER BY [ID] ASC) to try and help it.
Example output ( Select UniqueId, ID, ROWNR, Name from [REF].[View_Systems] ) :
UniqueId ID ROWNR Name
11 1 1 Amazon A
12 1 2 Amazon B
13 1 3 Amazon C
14 1 4 Amazon D
15 1 5 Amazon E
Table1:
[ID] [Name]
1 Amazon
Table2:
[ID] [Version]
1 A
1 B
1 C
1 D
1 E
CREATE VIEW [REF].[View_Systems]
AS
SELECT
CAST(CONCAT(CAST(TABA.[ID] AS VARCHAR(4)),
CAST(ROW_NUMBER() OVER(ORDER BY TABA.[ID] ASC) as VARCHAR(4))
) AS int) AS [UniqueId]
,TABA.[ID]
,ROW_NUMBER() OVER(ORDER BY TABA.[ID] ASC) AS ROWNR
,TABA.[Name]
FROM [Ref].[Table1] TABA LEFT JOIN [Ref].[Table2] TABB ON TABA.[ID] = TABB.[ID]
GO
UPDATE: Xcode 8 Update
Now with xcode 8 you can do:

Very simple steps to add Block Comment functionality to any editor of mac OS X
Add the below applescript in textarea
awk 'BEGIN{print "/*"}{print $0}END{print "*/"}'
Block Comment
Add a keyboard shortcut
Open System Preference > Keyboard > Shortcuts, add new shortcut by clicking +
and right the same name i.e. Block Comment
as you given to applescript in the 4th step. Add your Keyboard Shortcut and click Add button.
Now you should be able to use block comment in Xcode or any other editor, select some text, use your shortcut key to block comment any line of code or right click, the context menu, and the name you gave to this script should show near the bottom.
This works:
<script src="/clock.js" type="text/javascript"></script>
The leading slash means the root directory of your site. Strictly speaking, language="Javascript"
has been deprecated by type="text/javascript"
.
Capitalization of tags and attributes is also widely discouraged.
Both 'is' and 'as' are valid syntax. Output is disabled by default. Try a procedure that also enables output...
create or replace procedure temp_proc is
begin
DBMS_OUTPUT.ENABLE(1000000);
DBMS_OUTPUT.PUT_LINE('Test');
end;
...and call it in a PLSQL block...
begin
temp_proc;
end;
...as SQL is non-procedural.

Like you found, filter
accepts predicate function which accepts item
by item from the array.
So, you just have to create an predicate function based on the given criteria
.
In this example, criteriaMatch
is a function which returns a predicate
function which matches the given criteria
.
template:
<div ng-repeat="item in items | filter:criteriaMatch(criteria)">
{{ item }}
</div>
scope:
$scope.criteriaMatch = function( criteria ) {
return function( item ) {
return item.name === criteria.name;
};
};
This is a nice way to secure an upload filename:
$file_name = trim(basename(stripslashes($name)), ".\x00..\x20");
awk '{for (i=4; i<=NF; i++)printf("%c", $i); printf("\n");}'
prints records starting from the 4th field to the last field in the same order they were in the original file
Use float fabsf (float n)
for float

Use double fabs (double n)
for double

Use long double fabsl(long double)
for long double
values.
Use abs(int)
for int
values.
Do the following:

)This is a hacky way, but it's the easiest way to do this.
You can use Will Dean's suggestion [
#define arraysize(ar) (sizeof(ar) / sizeof(ar[0]))
] to replace the magic number 3 here with arraysize(str_array) -- although I remember there being some special case in which that particular version of arraysize might do Something Bad (sorry I can't remember the details immediately). But it very often works correctly.
The case where it doesn't work is when the "array" is really just a pointer, not an actual array. Also, because of the way arrays are passed to functions (converted to a pointer to the first element), it doesn't work across function calls even if the signature looks like an array — some_function(string parameter[])
is really some_function(string *parameter)
.
I am using Mac OS X 10.10 also. And to fix this problem.
Search and replace:
