In C++ language the result of the subexpresison is never affected by the surrounding context (with some rare exceptions). This is one of the principles that the language carefully follows. The expression c = a / b
contains of an independent subexpression a / b
, which is interpreted independently from anything outside that subexpression. The language does not care that you later will assign the result to a double
. a / b
is an integer division. Anything else does not matter. You will see this principle followed in many corners of the language specification. That's juts how C++ (and C) works.
One example of an exception I mentioned above is the function pointer assignment/initialization in situations with function overloading
void foo(int);
void foo(double);
void (*p)(double) = &foo; // automatically selects `foo(fouble)`
This is one context where the left-hand side of an assignment/initialization affects the behavior of the right-hand side. (Also, reference-to-array initialization prevents array type decay, which is another example of similar behavior.) In all other cases the right-hand side completely ignores the left-hand side.
insert into OPT (email, campaign_id)
select 'mom@coxnet' as email, 100 as campaign_id from dual MINUS
select email, campaign_id from OPT;
If there is already a record with [email protected]
/100
in OPT, the MINUS
will subtract this record from the select 'mom@coxnet' as email, 100 as campaign_id from dual
record and nothing will be inserted. On the other hand, if there is no such record, the MINUS
does not subract anything and the values mom@coxnet
/100
will be inserted.
As p.marino has already pointed out, merge
is probably the better (and more correct) solution for your problem as it is specifically designed to solve your task.
For global use, you may use:
$val = $_REQUEST['subject'];
and to add yo your session, simply
session_start();
$_SESSION['subject'] = $val;
And you dont need jQuery in this case.
For automation you definitely might wanna check out
webbot
Its is based on selenium and offers lot more features with very little code like automatically finding elements to perform actions like click , type based on the your parameters.
Its even works for sites with dynamically changing class names and ids .
Here is doc : https://webbot.readthedocs.io/
For Android Studio 0.4.0
and later, click "File > New > Image Asset
".
If you have several versions of Python installed, /usr/bin/env
will ensure the interpreter used is the first one on your environment's $PATH
. The alternative would be to hardcode something like #!/usr/bin/python
; that's ok, but less flexible.
In Unix, an executable file that's meant to be interpreted can indicate what interpreter to use by having a #!
at the start of the first line, followed by the interpreter (and any flags it may need).
If you're talking about other platforms, of course, this rule does not apply (but that "shebang line" does no harm, and will help if you ever copy that script to a platform with a Unix base, such as Linux, Mac, etc).
.... but how do we find the equivalent class in the second List to pass to the method below;
This is your actual problem; you must have at least one immutable property, a id or something like that, to identify corresponding objects in both lists. If you do not have such a property you, cannot solve the problem without errors. You can just try to guess corresponding objects by searching for minimal or logical changes.
If you have such an property, the solution becomes really simple.
Enumerable.Join(
listA, listB,
a => a.Id, b => b.Id,
(a, b) => CompareTwoClass_ReturnDifferences(a, b))
thanks to you both danbruc and Noldorin for your feedback. both Lists will be the same length and in the same order. so the method above is close, but can you modify this method to pass the enum.Current to the method i posted above?
Now I am confused ... what is the problem with that? Why not just the following?
for (Int32 i = 0; i < Math.Min(listA.Count, listB.Count); i++)
{
yield return CompareTwoClass_ReturnDifferences(listA[i], listB[i]);
}
The Math.Min() call may even be left out if equal length is guaranted.
Noldorin's implementation is of course smarter because of the delegate and the use of enumerators instead of using ICollection.
Simply you can set in php
file as
header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");
A note - when using ExtendScript JavaScript (the Adobe Scripting language used in applications like Photoshop CS3+), the character to use is "\r". "\n" will be interpreted as a font character, and many fonts will thus have a block character instead.
For example (to select a layer named 'Note' and add line feeds after all periods):
var layerText = app.activeDocument.artLayers.getByName('Note').textItem.contents;
layerText = layerText.replace(/\. /g,".\r");
You can use Twisted to verify certificates. The main API is CertificateOptions, which can be provided as the contextFactory
argument to various functions such as listenSSL and startTLS.
Unfortunately, neither Python nor Twisted comes with a the pile of CA certificates required to actually do HTTPS validation, nor the HTTPS validation logic. Due to a limitation in PyOpenSSL, you can't do it completely correctly just yet, but thanks to the fact that almost all certificates include a subject commonName, you can get close enough.
Here is a naive sample implementation of a verifying Twisted HTTPS client which ignores wildcards and subjectAltName extensions, and uses the certificate-authority certificates present in the 'ca-certificates' package in most Ubuntu distributions. Try it with your favorite valid and invalid certificate sites :).

All the answers so far are pretty flawed - they either involve adding class="noprint"
to everything or will mess up display
within #printable
.
I think the best solution would be to create a wrapper around the non-printable stuff:
<head>
<style type="text/css">
#printable { display: none; }
@media print
{
#non-printable { display: none; }
#printable { display: block; }
}
</style>
</head>
<body>
<div id="non-printable">
Your normal page contents
</div>
<div id="printable">
Printer version
</div>
</body>
Of course this is not perfect as it involves moving things around in your HTML a bit...
This hasn't solved my problem too, so I changed the parameters slightly.
This code worked for me:
var dataValue = "{ name: 'person', isGoing: 'true', returnAddress: 'returnEmail' }";
$.ajax({
type: "POST",
url: "Default.aspx/OnSubmit",
data: dataValue,
contentType: 'application/json; charset=utf-8',
dataType: 'json',
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
},
success: function (result) {
alert("We returned: " + result.d);
}
});

Swift 5 : For evenly distributed spaces between cells with dynamic cell width to make the best of container space you may use the code snippet below by providing a minimumCellWidth value.
private func collectionViewLayout() -> UICollectionViewLayout {
let layout = UICollectionViewFlowLayout()

// Important: if direction is horizontal use minimumItemSpacing instead.
layout.scrollDirection = .vertical
let itemHeight: CGFloat = 240
let minCellWidth :CGFloat = 130.0
let minItemSpacing: CGFloat = 10
let containerWidth: CGFloat = self.view.bounds.width
let maxCellCountPerRow: CGFloat = floor((containerWidth - minItemSpacing) / (minCellWidth+minItemSpacing ))
let itemWidth: CGFloat = floor( ((containerWidth - (2 * minItemSpacing) - (maxCellCountPerRow-1) * minItemSpacing) / maxCellCountPerRow ) )
// Calculate the remaining space after substracting calculating cellWidth (Divide by 2 because of left and right insets)
let inset = max(minItemSpacing, floor( (containerWidth - (maxCellCountPerRow*itemWidth) - (maxCellCountPerRow-1)*minItemSpacing) / 2 ) )

Here are the detailed steps needed to achieve this.
The existing commands can be simply run via the CLI terminal of VS-CODE. It is understood that Git is installed in the system, configured with desired username and email Id.
1) Navigate to the local project directory and create a local git repository:
git init
2) Once that is successful, click on the 'Source Control' icon on the left navbar in VS-Code.One should be able to see files ready to be commit-ed. Press on 'Commit' button, provide comments, stage the changes and commit the files. Alternatively you can run from CLI
git commit -m "Your comment"
3) Now you need to visit your GitHub account and create a new Repository. Exclude creating 'README.md', '.gitIgnore' files. Also do not add any License to the repo. Sometimes these settings cause issue while pushing in.
4) Copy the link to this newly created GitHub Repository.
5) Come back to the terminal in VS-CODE and type these commands in succession:
git remote add origin <Link to GitHub Repo> //maps the remote repo link to local git repo
git remote -v //this is to verify the link to the remote repo
git push -u origin master // pushes the commit-ed changes into the remote repo
Note: If it is the first time the local git account is trying to connect to GitHub, you may be required to enter credentials to GitHub in a separate window.
6) You can see the success message in the Terminal. You can also verify by refreshing the GitHub repo online.
Hope this helps
If you're on the Model Overview page you get a tab with the schema. If you rightclick on that tab you get an option to "edit schema". From there you can rename the schema by adding a new name, then click outside the field. This goes for MySQL Workbench 5.2.30 CE
Edit: On the model overview it's under Physical Schemata
Screenshot:
If you are using jQuery UI, you can format any date with:
<html>
<body>
Your date formated: <span id="date1"></span><br/>
</body>
</html>
var myDate = '30.11.2011';
var parsedDate = $.datepicker.parseDate('dd.mm.yy', myDate);
$('#date1').text($.datepicker.formatDate('M d, yy', parsedDate));
Check the project properties. It's configurable there if you are using another .net windows application for example
If like me you recently moved certain classes to different packages ect. and you use android navigation. Make sure to change the argType to you match you new package address. from:
app:argType="com.example.app.old.Item"
to:
app:argType="com.example.app.new.Item"
This is completely redundant. empty
is more or less shorthand for !isset($foo) || !$foo
, and !empty
is analogous to isset($foo) && $foo
. I.e. empty
does the reverse thing of isset
plus an additional check for the truthiness of a value.
Or in other words, empty
is the same as !$foo
, but doesn't throw warnings if the variable doesn't exist. That's the main point of this function: do a boolean comparison without worrying about the variable being set.
The manual puts it like this:
empty()
is the opposite of(boolean) var
, except that no warning is generated when the variable is not set.
You can simply use !empty($vars[1])
here.

In this case, there is a method for finding the smallest of three doubles available in org.apache.commons.lang.math.NumberUtils. Their implementation is actually nearly identical to your initial thought:

As explained above by @kris, depending on the region configurations of MS Excel it won't interpret the comma as the separator character. In my case I had to change it to semi-colon
I had a similar situation: I needed to purge postgresql 9.1 on a debian wheezy ( I had previously migrated from 8.4 and I was getting errors ).
What I did:
First, I deleted config and database
$ sudo pg_dropcluster --stop 9.1 main
Then removed postgresql
$ sudo apt-get remove --purge postgresql postgresql-9.1
and then reinstalled
$ sudo apt-get install postgresql postgresql-9.1
In my case I noticed /etc/postgresql/9.1 was empty, and running service postgresql start
returned nothing
So, after more googling I got to this command:
$ sudo pg_createcluster 9.1 main
With that I could start the server, but now I was getting log-related errors. After more searching, I ended up changing permissions to the /var/log/postgresql directory
$ sudo chown root.postgres /var/log/postgresql
$ sudo chmod g+wx /var/log/postgresql
That fixed the issue, Hope this helps
Do not use a union
!
C++ does not permit type punning via union
s!
Reading from a union field that was not the last field written to is undefined behaviour!
Many compilers support doing so as an extensions, but the language makes no guarantee.
See this answer for more details:
https://stackoverflow.com/a/11996970
There are only two valid answers that are guaranteed to be portable.
The first answer, if you have access to a system that supports C++20,
is to use std::endian
from the <type_traits>
header.
(At the time of writing, C++20 has not yet been released, but unless something happens to affect std::endian
's inclusion, this shall be the preferred way to test the endianness at compile time from C++20 onwards.)
constexpr bool is_little_endian = (std::endian::native == std::endian::little);
Prior to C++20, the only valid answer is to store an integer and then inspect its first byte through type punning.
Unlike the use of union
s, this is expressly allowed by C++'s type system.
It's also important to remember that for optimum portability static_cast
should be used,
because reinterpret_cast
is implementation defined.
If a program attempts to access the stored value of an object through a glvalue of other than one of the following types the behavior is undefined: ... a
char
orunsigned char
type.
enum class endianness
{
little = 0,
big = 1,
};
inline endianness get_system_endianness()
{
const int value { 0x01 };
const void * address = static_cast<const void *>(&value);
const unsigned char * least_significant_address = static_cast<const unsigned char *>(address);
return (*least_significant_address == 0x01) ? endianness::little : endianness::big;
}
inline bool is_system_little_endian()
{
const int value { 0x01 };
const void * address = static_cast<const void *>(&value);
const unsigned char * least_significant_address = static_cast<const unsigned char *>(address);
return (*least_significant_address == 0x01);
}
inline bool is_system_little_endian()
{
const int value = 0x01;
const void * address = static_cast<const void *>(&value);
const unsigned char * least_significant_address = static_cast<const unsigned char *>(address);
return (*least_significant_address == 0x01);
}
If you have installed anaconda, but if you are not able to execute conda command from terminal, it means the path is not probably set, try :

According to some comments on Super User it still works :) It just should be copied back to the plugins folder (if it's in the disabled folder) or downloaded from Plugins Central. I have downloaded it a few minutes ago and succeeded in using it.
Of course, be warned: this plugin COULD be unstable in some situations - that's why it was disabled.

did not work for me; the rest of the line (//g, replacement);

R defines a ~
(tilde) operator for use in formulas. Formulas have all sorts of uses, but perhaps the most common is for regression:
library(datasets)
lm( myFormula, data=iris)
help("~")
or help("formula")
will teach you more.
@Spacedman has covered the basics. Let's discuss how it works.
First, being an operator, note that it is essentially a shortcut to a function (with two arguments):
> `~`(lhs,rhs)
lhs ~ rhs
> lhs ~ rhs
lhs ~ rhs
That can be helpful to know for use in e.g. apply
family commands.
Second, you can manipulate the formula as text:
oldform <- as.character(myFormula) # Get components
myFormula <- as.formula( paste( oldform[2], "Sepal.Length", sep="~" ) )
Third, you can manipulate it as a list:
myFormula[[2]]
myFormula[[3]]
Finally, there are some helpful tricks with formulae (see help("formula")
for more):
myFormula <- Species ~ .
For example, the version above is the same as the original version, since the dot means "all variables not yet used." This looks at the data.frame you use in your eventual model call, sees which variables exist in the data.frame but aren't explicitly mentioned in your formula, and replaces the dot with those missing variables.
I do this using associative arrays since bash 4 and setting IFS
to a value that can be defined manually.
The purpose of this approach is to have arrays as values of associative array keys.
In order to set IFS back to default just unset it.
unset IFS
This is an example:
#!/bin/bash
set -euo pipefail
# used as value in asscciative array
test=(
"x3:x4:x5"
)
# associative array
declare -A wow=(
["1"]=$test
["2"]=$test
)
echo "default IFS"
for w in ${wow[@]}; do
echo " $w"
done
IFS=:
echo "IFS=:"
for w in ${wow[@]}; do
for t in $w; do
echo " $t"
done
done
echo -e "\n or\n"
for w in ${!wow[@]}
do
echo " $w"
for t in ${wow[$w]}
do
echo " $t"
done
done
unset IFS
unset w
unset t
unset wow
unset test
The output of the script below is:
default IFS
x3:x4:x5
x3:x4:x5
IFS=:
x3
x4
x5
x3
x4
x5
or
1
x3
x4
x5
2
x3
x4
x5
It specifies the size of the log file to trigger rotation. For example size 50M
will trigger a log rotation once the file is 50MB or greater in size. You can use the suffix M
for megabytes, k
for kilobytes, and G
for gigabytes. If no suffix is used, it will take it to mean bytes. You can check the example at the end. There are three directives available size
, maxsize
, and minsize
. According to manpage:
minsize size
Log files are rotated when they grow bigger than size bytes,
but not before the additionally specified time interval (daily,
weekly, monthly, or yearly). The related size option is simi-
lar except that it is mutually exclusive with the time interval
options, and it causes log files to be rotated without regard
for the last rotation time. When minsize is used, both the
size and timestamp of a log file are considered.
size size
Log files are rotated only if they grow bigger then size bytes.
If size is followed by k, the size is assumed to be in kilo-
bytes. If the M is used, the size is in megabytes, and if G is
used, the size is in gigabytes. So size 100, size 100k, size
100M and size 100G are all valid.
maxsize size
Log files are rotated when they grow bigger than size bytes even before
the additionally specified time interval (daily, weekly, monthly,
or yearly). The related size option is similar except that it
is mutually exclusive with the time interval options, and it causes
log files to be rotated without regard for the last rotation time.
When maxsize is used, both the size and timestamp of a log file are
considered.
Here is an example:
"/var/log/httpd/access.log" /var/log/httpd/error.log {
rotate 5
mail [email protected]
size 100k
sharedscripts
postrotate
/usr/bin/killall -HUP httpd
endscript
}
Here is an explanation for both files /var/log/httpd/access.log
and /var/log/httpd/error.log
. They are rotated whenever it grows over 100k in size, and the old logs files are mailed (uncompressed) to [email protected]
after going through 5 rotations, rather than being removed. The sharedscripts
means that the postrotate
script will only be run once (after the old logs have been compressed), not once for each log which is rotated. Note that the double quotes around the first filename at the beginning of this section allows logrotate to rotate logs with spaces in the name. Normal shell quoting rules apply, with ,
, and \
characters supported.
Some examples on working with nullable DateTime
values.
(See Nullable Value Types (Visual Basic) for more.)
'
' An ordinary DateTime declaration. It is *not* nullable. Setting it to
' 'Nothing' actually results in a non-null value.
'
Dim d1 As DateTime = Nothing
Console.WriteLine(String.Format("d1 = [{0}]\n", d1))
' Output: d1 = [1/1/0001 12:00:00 AM]
' Console.WriteLine(String.Format("d1 is Nothing? [{0}]\n", (d1 Is Nothing)))
'
' Compilation error on above expression '(d1 Is Nothing)':
'
' 'Is' operator does not accept operands of type 'Date'.
' Operands must be reference or nullable types.
'
' Three different but equivalent ways to declare a DateTime
' nullable:
'
Dim d2? As DateTime = Nothing
Console.WriteLine(String.Format("d2 = [{0}][{1}]\n", d2, (d2 Is Nothing)))
' Output: d2 = [][True]
Dim d3 As DateTime? = Nothing
Console.WriteLine(String.Format("d3 = [{0}][{1}]\n", d3, (d3 Is Nothing)))
' Output: d3 = [][True]
Dim d4 As Nullable(Of DateTime) = Nothing
Console.WriteLine(String.Format("d4 = [{0}][{1}]\n", d4, (d4 Is Nothing)))
' Output: d4 = [][True]
Also, on how to check whether a variable is null (from Nothing (Visual Basic)):
When checking whether a reference (or nullable value type) variable is null, do not use= Nothing
or<> Nothing
. Always useIs Nothing
orIsNot Nothing
.
try something like this :
$.ajax({
type: 'POST',
url: 'loginCheck',
data: $(formLogin).serialize(),
dataType: 'json',
success: function (textStatus, status) {
console.log(textStatus);
console.log(status);
},
error: function(xhr, textStatus, error) {
console.log(xhr.responseText);
console.log(xhr.statusText);
console.log(textStatus);
console.log(error);
}
});
Like others mentioned you cannot delete current branch in which you are working.
In my case, I have selected "Test_Branch" in Visual Studio and was trying to delete "Test_Branch" from Sourcetree (Git GUI). And was getting below error message.
Cannot delete branch 'Test_Branch' checked out at '[directory location]'.
Switched to different branch in Visual Studio and was able to delete "Test_Branch" from Sourcetree.
I hope this helps someone who is using Visual Studio & Sourcetree.
This is because in Mac OS X there is already Apache pre-installed. So what you can do is to change the listening port of one of the Apaches, either the Apache that you installed with XAMPP or the pre-installed one.
To change the listening port for XAMPP's Apache, go to /Applications/XAMPP/xamppfiles/etc and edit httpd.conf. Change the line "Listen 80" (80 is the listening port) to other port, eg. "Listen 1234".
Or,
To change the one for pre-installed Apache, go to /etc/apache2. You can do the same thing with file httpd.conf there.
After changing you might need to restart your Mac, just to make sure.
For Files - svn revert filename
For Folders - svn revert -R folder
I have replaced the printf
calls with calls to warning
in the C-code now. It will be effective in the version 2.17.2 which should be available tomorrow night. Then you should be able to avoid the warnings with suppressWarnings()
or any of the other above mentioned methods.
suppressWarnings({ your code })
I think you've forgotten initialize your string "str": You need initialize the string before using strcat. And also you need that tmp were a string, not a single char. Try change this:
char str[1024]; // Only declares size
char tmp = '.';
for
char str[1024] = "Hello World"; //Now you have "Hello World" in str
char tmp[2] = ".";
It is bad practice to catch Exception -- it's just too broad, and you may miss something like a NullPointerException in your own code.
For most file operations, IOException is the root exception. Better to catch that, instead.

There are two options depending what you want to achieve :
You can use the hidden directive to show or hide an element
<div [hidden]="!edited" class="alert alert-success box-msg" role="alert">
<strong>List Saved!</strong> Your changes has been saved.
</div>
You can use the ngIf control directive to add or remove the element. This is different of the hidden directive because it does not show / hide the element, but it add / remove from the DOM. You can loose unsaved data of the element. It can be the better choice for an edit component that is cancelled.
<div *ngIf="edited" class="alert alert-success box-msg" role="alert">
<strong>List Saved!</strong> Your changes has been saved.
</div>
For you problem of change after 3 seconds, it can be due to incompatibility with setTimeout. Did you include angular2-polyfills.js library in your page ?
Extending upon Mustafa's answer.
A) Install http://phantomjs.org/ and then
B) install the phantom node module https://github.com/amir20/phantomjs-node
C) Here is an example of rendering a pdf
var phantom = require('phantom');
phantom.create().then(function(ph) {
ph.createPage().then(function(page) {
page.open("http://www.google.com").then(function(status) {
page.render('google.pdf').then(function() {
console.log('Page Rendered');
ph.exit();
});
});
});
});
Output of the PDF:
EDIT: Silent printing that PDF
java -jar pdfbox-app-2.0.2.jar PrintPDF -silentPrint C:\print_mypdf.pdf
If the verification logic is non-trivial, it will be messy to write a large lambda method (as your example shows). You could put all the test statements in a separate method, but I don't like to do this because it disrupts the flow of reading the test code.
Another option is to use a callback on the Setup call to store the value that was passed into the mocked method, and then write standard Assert
methods to validate it. For example:
// Arrange
MyObject saveObject;
mock.Setup(c => c.Method(It.IsAny<int>(), It.IsAny<MyObject>()))
.Callback<int, MyObject>((i, obj) => saveObject = obj)
.Returns("xyzzy");
// Act
// ...
// Assert
// Verify Method was called once only
mock.Verify(c => c.Method(It.IsAny<int>(), It.IsAny<MyObject>()), Times.Once());
// Assert about saveObject
Assert.That(saveObject.TheProperty, Is.EqualTo(2));
Straight from the horse's mouth:
If you prefer to have dict-like view of the attributes, you can use the standard Python idiom,
vars()
:>>> parser = argparse.ArgumentParser() >>> parser.add_argument('--foo') >>> args = parser.parse_args(['--foo', 'BAR']) >>> vars(args) {'foo': 'BAR'}
— The Python Standard Library, 16.4.4.6. The Namespace object

First save your program as program.c
.
Now you need the compiler, so you need to go to App Store and install Xcode which is Apple's compiler and development tools. How to find App Store? Do a "Spotlight Search" by typing ⌘Space and start typing App Store
and hit Enter when it guesses correctly.
App Store looks like this:
Xcode looks like this on App Store:
Then you need to install the command-line tools in Terminal. How to start Terminal? You need to do another "Spotlight Search", which means you type ⌘Space and start typing Terminal
and hit Enter when it guesses Terminal
.
Now install the command-line tools like this:
xcode-select --install
Then you can compile your code with by simply running gcc
as in the next line without having to fire up the big, ugly software development GUI called Xcode
:
gcc -Wall -o program program.c
Note: On newer versions of OS X, you would use clang
instead of gcc
, like this:
clang program.c -o program
Then you can run it with:
./program
Hello, world!
If your program is C++, you'll probably want to use one of these commands:
clang++ -o program program.cpp
g++ -std=c++11 -o program program.cpp
g++-7 -std=c++11 -o program program.cpp
For me, the issue was having an extra node_modules
folder that I renamed to node_modules_old
and running an npm install
to generate a fresh node_modules
. Somehow the build must have still been picking up the node_modules_old
folder, so I moved node_modules_old
out of the directory to fix the issue.
The padding inside a table-divider (TD) is a padding property applied to the cell itself.
CSS
td, th {padding:0}
The spacing in-between the table-dividers is a space between cell borders of the TABLE. To make it effective, you have to specify if your table cells borders will 'collapse' or be 'separated'.
CSS
table, td, th {border-collapse:separate}
table {border-spacing:6px}

Faced the same problem, I was not able to run wordpress docker container with mysql version 8 as its default authentication mechanism is caching_sha2_password instead of mysql_native_password.
In order to fix this problem we must reset default authentication mechanism to mysql_native_password.
Find my.cnf file in your mysql installation, usually on a linux machine it is at the following location - /etc/mysql
Edit my.cnf file and add following line just under heading [mysqld]
default_authentication_plugin= mysql_native_password
Save the file then log into mysql command line using root user
run command FLUSH PRIVILEGES;
In my case I was launching a WKWebView and displaying a website. Then (within 25 seconds) I deallocated the WKWebView. But 25-60 seconds after launching the WKWebView I received this "113" error message. I assume the system was trying to signal something to the WKWebView and couldn't find it because it was deallocated.
The fix was simply to leave the WKWebView allocated.
in windows 7 this returns the desktop path:

I'm guessing that you're referring to the fact that you often have to put a 'return false;' statement in your event handlers, i.e.
<a href="#" onclick="doSomeFunction(); return false;">...
The 'return false;' in this case stops the browser from jumping to the current location, as indicated by the href="#" - instead, only doSomeFunction() is executed. It's useful for when you want to add events to anchor tags, but don't want the browser jumping up and down to each anchor on each click
Unlike proposed by Nicolas, the meta
tag isn’t actually ignored by the browsers. However, the Content-Type
HTTP header always has precedence over the presence of a meta
tag in the document.
So make sure that you either send the correct encoding via the HTTP header, or don’t send this HTTP header at all (not recommended). The meta
tag is mainly a fallback option for local documents which aren’t sent via HTTP traffic.
Using HTML entities should also be considered a workaround – that’s tiptoeing around the real problem. Configuring the web server properly prevents a lot of nuisance.
In JDK 1.7, you can get system CPU and memory usage via com.sun.management.OperatingSystemMXBean
. This is different than java.lang.management.OperatingSystemMXBean
.
long getCommittedVirtualMemorySize()
Returns the amount of virtual memory that is guaranteed to be available to the running process in bytes, or -1 if this operation is not supported.
long getFreePhysicalMemorySize()
Returns the amount of free physical memory in bytes.
long getFreeSwapSpaceSize()
Returns the amount of free swap space in bytes.
double getProcessCpuLoad()
Returns the "recent cpu usage" for the Java Virtual Machine process.
long getProcessCpuTime()
Returns the CPU time used by the process on which the Java virtual machine is running in nanoseconds.
double getSystemCpuLoad()
Returns the "recent cpu usage" for the whole system.
long getTotalPhysicalMemorySize()
Returns the total amount of physical memory in bytes.
long getTotalSwapSpaceSize()
Returns the total amount of swap space in bytes.

You could just add a space before and after "word".
x = raw_input("Type your word: ")
if " word " in x:
print "Yes"
elif " word " not in x:

Here is a very simplified explanation:
Your web browser downloads the web server's certificate, which contains the public key of the web server. This certificate is signed with the private key of a trusted certificate authority.
Your web browser comes installed with the public keys of all of the major certificate authorities. It uses this public key to verify that the web server's certificate was indeed signed by the trusted certificate authority.
The certificate contains the domain name and/or ip address of the web server. Your web browser confirms with the certificate authority that the address listed in the certificate is the one to which it has an open connection.
Your web browser generates a shared symmetric key which will be used to encrypt the HTTP traffic on this connection; this is much more efficient than using public/private key encryption for everything. Your browser encrypts the symmetric key with the public key of the web server then sends it back, thus ensuring that only the web server can decrypt it, since only the web server has its private key.
Note that the certificate authority (CA) is essential to preventing man-in-the-middle attacks. However, even an unsigned certificate will prevent someone from passively listening in on your encrypted traffic, since they have no way to gain access to your shared symmetric key.
If you put together the answers so far, clean up and improve, you would arrive at this superior query:
UPDATE sales
SET status = 'ACTIVE'
WHERE (saleprice, saledate) IN (
SELECT saleprice, saledate
FROM sales
GROUP BY saleprice, saledate
HAVING count(*) = 1
);
Which is much faster than either of them. Nukes the performance of the currently accepted answer by factor 10 - 15 (in my tests on PostgreSQL 8.4 and 9.1).
But this is still far from optimal. Use a NOT EXISTS
(anti-)semi-join for even better performance. EXISTS
is standard SQL, has been around forever (at least since PostgreSQL 7.2, long before this question was asked) and fits the presented requirements perfectly:
UPDATE sales s
SET status = 'ACTIVE'
WHERE NOT EXISTS (
SELECT FROM sales s1 -- SELECT list can be empty for EXISTS
WHERE s.saleprice = s1.saleprice
AND s.saledate = s1.saledate
AND s.id <> s1.id -- except for row itself
)
AND s.status IS DISTINCT FROM 'ACTIVE'; -- avoid empty updates. see below
db<>fiddle here
Old SQL Fiddle
If you don't have a primary or unique key for the table (id
in the example), you can substitute with the system column ctid
for the purpose of this query (but not for some other purposes):
AND s1.ctid <> s.ctid
Every table should have a primary key. Add one if you didn't have one, yet. I suggest a serial
or an IDENTITY
column in Postgres 10+.
Related:
The subquery in the EXISTS
anti-semi-join can stop evaluating as soon as the first dupe is found (no point in looking further). For a base table with few duplicates this is only mildly more efficient. With lots of duplicates this becomes way more efficient.
For rows that already have status = 'ACTIVE'
this update would not change anything, but still insert a new row version at full cost (minor exceptions apply). Normally, you do not want this. Add another WHERE
condition like demonstrated above to avoid this and make it even faster:
If status
is defined NOT NULL
, you can simplify to:
AND status <> 'ACTIVE';
The data type of the column must support the <>
operator. Some types like json
don't. See:
This query (unlike the currently accepted answer by Joel) does not treat NULL values as equal. The following two rows for (saleprice, saledate)
would qualify as "distinct" (though looking identical to the human eye):
(123, NULL)
(123, NULL)
Also passes in a unique index and almost anywhere else, since NULL values do not compare equal according to the SQL standard. See:
OTOH, GROUP BY
, DISTINCT
or DISTINCT ON ()
treat NULL values as equal. Use an appropriate query style depending on what you want to achieve. You can still use this faster query with IS NOT DISTINCT FROM
instead of =
for any or all comparisons to make NULL compare equal. More:
If all columns being compared are defined NOT NULL
, there is no room for disagreement.
You are using jQuery, right? Separate JavaScript from HTML.
You can use trigger or triggerHandler.
var $myInput = $('#changeProgramatic').on('change', ChangeValue);
var anotherFunction = function() {
$myInput.val('Another value');
$myInput.trigger('change');
};

You can use string.match() and a regular expression for this too:
if(pathname.match(/^\/sub\/1/)) { // you need to escape the slashes
string.match()
will return an array of matching substrings if found, otherwise null.
system()
executes a shell which is then responsible for parsing the arguments and executing the desired program. To execute the program directly, use fork() and exec() (which is what system() uses to execute the shell as well as what the shell itself uses to execute commands).
#include <unistd.h>
int main() {
if (fork() == 0) {
/*
* fork() returns 0 to the child process
* and the child's PID to the parent.
*/
execl("/path/to/foo", "foo", "arg1", "arg2", "arg3", 0);
/*
* We woundn't still be here if execl() was successful,
* so a non-zero exit value is appropriate.
*/
return 1;
}
return 0;
}
Unfortunately, vars files do not have include statements.
You can either put all the vars into the definitions
dictionary, or add the variables as another dictionary in the same file.
If you don't want to have them in the same file, you can include them at the playbook level by adding the vars file at the start of the play:
---
- hosts: myhosts
vars_files:
- default_step.yml
or in a task:
---
- hosts: myhosts
tasks:
- name: include default step variables
include_vars: default_step.yml

If you submit the form via Javascript (i.e. formElement.submit()
or anything equivalent), then none of the submit buttons are considered successful and none of their values are included in the submitted data. (Note that if you submit the form by using submitElement.click()
then the submit that you had a reference to is considered active; this doesn't really fall under the remit of your question since here the submit button is unambiguous but I thought I'd include it for people who read the first part and wonder how to make a submit button successful via JS form submission. Of course, the form's onsubmit handlers will still fire this way whereas they wouldn't via form.submit()
so that's another kettle of fish...)
If the form is submitted by hitting Enter while in a non-textarea field, then it's actually down to the user agent to decide what it wants here. The specs don't say anything about submitting a form using the enter key while in a text entry field (if you tab to a button and activate it using space or whatever, then there's no problem as that specific submit button is unambiguously used). All it says is that a form must be submitted when a submit button is activated, it's not even a requirement that hitting enter in e.g. a text input will submit the form.
I believe that Internet Explorer chooses the submit button that appears first in the source; I have a feeling that Firefox and Opera choose the button with the lowest tabindex, falling back to the first defined if nothing else is defined. There's also some complications regarding whether the submits have a non-default value attribute IIRC.
The point to take away is that there is no defined standard for what happens here and it's entirely at the whim of the browser - so as far as possible in whatever you're doing, try to avoid relying on any particular behaviour. If you really must know, you can probably find out the behaviour of the various browser versions but when I investigated this a while back there were some quite convoluted conditions (which of course are subject to change with new browser versions) and I'd advise you to avoid it if possible!
You can do that but the changes will affect for new data that is inserted on the database. On the long run follow as suggested above.
Also there are certain tricks you can override the collation, such as parameters for stored procedures or functions, alias data types, and variables are assigned the default collation of the database. To change the collation of an alias type, you must drop the alias and re-create it.
You can override the default collation of a literal string by using the COLLATE clause. If you do not specify a collation, the literal is assigned the database default collation. You can use DATABASEPROPERTYEX to find the current collation of the database.
You can override the server, database, or column collation by specifying a collation in the ORDER BY clause of a SELECT statement.

I struggled to understand the proxy settings for websockets for https therefore let me put clarity here what i realized.
First you need to enable proxy
and proxy_wstunnel
apache modules and the apache configuration file will look like this.
<IfModule mod_ssl.c>
<VirtualHost _default_:443>
ServerName www.example.com
ServerAdmin webmaster@localhost
DocumentRoot /var/www/your_project_public_folder
SSLEngine on
SSLCertificateFile /etc/ssl/certs/path_to_your_ssl_certificate
SSLCertificateKeyFile /etc/ssl/private/path_to_your_ssl_key
<Directory /var/www/your_project_public_folder>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
php_flag display_errors On
</Directory>
ProxyRequests Off
ProxyPass /wss/ ws://example.com:port_no
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
</IfModule>
in your frontend application use the url "wss://example.com/wss/"
this is very important mostly if you are stuck with websockets you might be making mistake in the front end url. You probably putting url wrongly like below.
wss://example.com:8080/wss/ -> port no should not be mentioned
ws://example.com/wss/ -> url should start with wss only.
wss://example.com/wss -> url should end with / -> most important
also interesting part is the last /wss/
is same as proxypass
value if you writing proxypass /ws/
then in the front end you should write /ws/
in the end of url.
You can use sql in your conditions:
Topic.find(:all, :conditions => [ "forum_id NOT IN (?)", @forums.map(&:id)])
It's not the best answer, but its also an option: since you can concatenate multiple expressions, but just the last one is rendered, you can finish your expression with ""
and your variable will be hidden.
So, you could define the variable with:
{{f = forecast[day.iso]; ""}}
You could try this:
string input = "lala.bla";
output = input.Split('.').Last();

Turns out question has been asked before: How can I get the currently logged-in windows user in Access VBA?
With ECMAScript 6, you can use variable property names with the object literal syntax, like this:
var keyName = 'myKey';
var obj = {
[keyName]: 1
};
obj.myKey;//1
This syntax is available in the following newer browsers:
Edge 12+ (No IE support), FF34+, Chrome 44+, Opera 31+, Safari 7.1+
(https://kangax.github.io/compat-table/es6/)
You can add support to older browsers by using a transpiler such as babel. It is easy to transpile an entire project if you are using a module bundler such as rollup or webpack.
This error also comes when you run the command
node filename.ts
and not
node filename.js
To simply put, with node command we will have to run the JavaScript file (filename.js) and not the TypeScript file unless we are using a package like ts-node
On a mac you have to set keybinding yourself. Simply go to
Sublime --> Preference --> Key Binding - User
and input the following:
{ "keys": ["shift+command+m"], "command": "goto_definition" }
This will enable keybinding of Shift + Command + M
to enable goto definition. You can set the keybinding to anything you would like of course.
If you want that behavior for all commands in your script, just add
set -e
set -o pipefail
at the beginning of the script. This pair of options tell the bash interpreter to exit whenever a command returns with a non-zero exit code.
This does not allow you to print an exit message, though.
AJB's "Option B" can be made to work by using the base Ubuntu image and setting up nginx on your own. (It didn't work when I used the Nginx image from Docker Hub.)
Here is the Docker file I used:
FROM ubuntu
RUN apt-get update && apt-get install -y nginx
RUN ln -sf /dev/stdout /var/log/nginx/access.log
RUN ln -sf /dev/stderr /var/log/nginx/error.log
RUN rm -rf /etc/nginx/sites-enabled/default
EXPOSE 80 443
COPY conf/mysite.com /etc/nginx/sites-enabled/mysite.com
CMD ["nginx", "-g", "daemon off;"]
My nginx config (aka: conf/mysite.com):
server {
listen 80 default;
server_name mysite.com;
location / {
proxy_pass http://website;
}
}
upstream website {
server website:3000;
}
And finally, how I start my containers:
$ docker run -dP --name website website
$ docker run -dP --name nginx --link website:website nginx
This got me up and running so my nginx pointed the upstream to the second docker container which exposed port 3000.
I had the same question as soon as I read about DI and ended up at this post. So finally this is what I understood but please correct me if am wrong.

1920 is a generic error code that means the service didn't start. My hunch is this:
http://blog.iswix.com/2008/09/different-year-same-problem.html
To confirm, with the installer on the abort, retry, ignore, cancel dialog up... go into services.msc and set the username and password manually. If you get a message saying the user was granted logon as service right, try hitting retry on the MSI dialog and see if it starts.
It could also be missing dependencies or exceptions being thrown in your code.
I used the most voted option and created a function that would clean one array of words using another array of unwanted words:
function cleanArrayOfSpecificTerms(array,unwantedTermsArray) {
$.each(unwantedTermsArray, function( index, value ) {
var index = array.indexOf(value);
if (index > -1) {
array.splice(index, 1);
}
});
return array;
}
To use, do the following:
var notInclude = ['Not','No','First','Last','Prior','Next', 'dogs','cats'];
var splitTerms = ["call", "log", "dogs", "cats", "topic", "change", "pricing"];
cleanArrayOfSpecificTerms(splitTerms,notInclude)
While quicksort is often a better choice than merge sort, there are definitely times when merge sort is thereotically a better choice. The most obvious time is when it's extremely important that your algorithm run faster than O(n^2). Quicksort is usually faster than this, but given the theoretical worst possible input, it could run in O(n^2), which is worse than the worst possible merge sort.
Quicksort is also more complicated than mergesort, especially if you want to write a really solid implementation, and so if you're aiming for simplicity and maintainability, merge sort becomes a promising alternative with very little performance loss.
These are timeout values enforced by JVM for TCP connection establishment and waiting on reading data from socket.
If the value is set to infinity, you will not wait forever. It simply means JVM doesn't have timeout and OS will be responsible for all the timeouts. However, the timeouts on OS may be really long. On some slow network, I've seen timeouts as long as 6 minutes.
Even if you set the timeout value for socket, it may not work if the timeout happens in the native code. We can reproduce the problem on Linux by connecting to a host blocked by firewall or unplugging the cable on switch.
The only safe approach to handle TCP timeout is to run the connection code in a different thread and interrupt the thread when it takes too long.
Most answers are surprisingly complicated or erroneous. However simple and robust examples have been posted elsewhere [codereview]. Admittedly the options provided by the gnu preprocessor are a bit confusing. However, the removal of all directories from the build target with -MM
is documented and not a bug [gpp]:
By default CPP takes the name of the main input file, deletes any directory components and any file suffix such as ‘.c’, and appends the platform's usual object suffix.
The (somewhat newer) -MMD
option is probably what you want. For completeness an example of a makefile that supports multiple src dirs and build dirs with some comments. For a simple version without build dirs see [codereview].

CXX_FLAGS = -Wfatal-errors -Wall -Wextra -Wpedantic -Wconversion -Wshadow

CPP = main.cpp $(wildcard dir1/*.cpp) $(wildcard dir2/*.cpp)
# All .o files go to build dir.
OBJ = $(CPP:%.cpp=$(BUILD_DIR)/%.o)
# Gcc/Clang will create these .d files containing dependencies.
DEP = $(OBJ:%.o=%.d)
# Default target named after the binary.
$(BIN) : $(BUILD_DIR)/$(BIN)
# Actual target of the binary - depends on all .o files.
$(BUILD_DIR)/$(BIN) : $(OBJ)
# Create build directories - same structure as sources.
mkdir -p $(@D)
# Just link all the object files.
$(CXX) $(CXX_FLAGS) $^ -o $@
# Include all .d files
-include $(DEP)
# Build target for every single object file.
# The potential dependency on header files is covered
# by calling `-include $(DEP)`.
$(BUILD_DIR)/%.o : %.cpp
mkdir -p $(@D)
# The -MMD flags additionaly creates a .d file with
# the same name as the .o file.
$(CXX) $(CXX_FLAGS) -MMD -c $< -o $@
.PHONY : clean
clean :
# This should remove all generated files.
-rm $(BUILD_DIR)/$(BIN) $(OBJ) $(DEP)
This method works because if there are multiple dependency lines for a single target, the dependencies are simply joined, e.g.:
a.o: a.h
a.o: a.c
./cmd
is equivalent to:
a.o: a.c a.h
./cmd
as mentioned at: Makefile multiple dependency lines for a single target?
The simplest way I found to just send raw XML to a SOAP service using Node.js is to use the Node.js http implementation. It looks like this.
var http = require('http');
var http_options = {
hostname: 'localhost',
port: 80,
path: '/LocationOfSOAPServer/',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': xml.length
}
}
var req = http.request(http_options, (res) => {
console.log(`STATUS: ${res.statusCode}`);
console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
res.setEncoding('utf8');
res.on('data', (chunk) => {
console.log(`BODY: ${chunk}`);
});
res.on('end', () => {
console.log('No more data in response.')
})
});
req.on('error', (e) => {
console.log(`problem with request: ${e.message}`);
});
// write data to request body
req.write(xml); // xml would have been set somewhere to a complete xml document in the form of a string
req.end();
You would have defined the xml variable as the raw xml in the form of a string.
But if you just want to interact with a SOAP service via Node.js and make regular SOAP calls, as opposed to sending raw xml, use one of the Node.js libraries. I like node-soap.
Simply with command line:
javac MyApp.java
jar -cf myJar.jar MyApp.class
Sure IDEs avoid using command line terminal
Your best solution is to look at the "opacity" tag of an element.
For example:
.image
{
opacity:0.4;
filter:alpha(opacity=40); /* For IE8 and earlier */
}
So in your case it should look something like :
<html><span style="opacity: 0.5;"><font color=\"black\" face=\"arial\" size=\"4\">THIS IS MY TEXT</font></html>
However don't forget the tag isn't supported in HTML5.
You should use a CSS too :)
This solution works using Bootstrap v2, however in TBS3 the class INLINE. I haven't figured out what is the equivalent class (if there is one) in TBS3.
This gentleman had a pretty good article of the differences between v2 and v3.
http://mattduchek.com/differences-between-bootstrap-v2-3-and-v3-0/
EDIT - use CSS to target the li
elements to solve your problem as below
{ display: inline-block; }
In my situation I was targeting the UL, instead of the LI
nav ul li { display: inline-block; }

Seeing as everyone seems to get directed here for this issue, I'm adding my answer to a similar question, which contains the same code as this answer but with full background for those who are interested:
IE's document.selection.createRange doesn't include leading or trailing blank lines
To account for trailing line breaks is tricky in IE, and I haven't seen any solution that does this correctly, including any other answers to this question. It is possible, however, using the following function, which will return you the start and end of the selection (which are the same in the case of a caret) within a <textarea>
or text <input>
.
Note that the textarea must have focus for this function to work properly in IE. If in doubt, call the textarea's focus()
method first.
function getInputSelection(el) {
var start = 0, end = 0, normalizedValue, range,
textInputRange, len, endRange;
if (typeof el.selectionStart == "number" && typeof el.selectionEnd == "number") {
start = el.selectionStart;
end = el.selectionEnd;
} else {
range = document.selection.createRange();
if (range && range.parentElement() == el) {
len = el.value.length;
normalizedValue = el.value.replace(/\r\n/g, "\n");
// Create a working TextRange that lives only in the input
textInputRange = el.createTextRange();
textInputRange.moveToBookmark(range.getBookmark());
// Check if the start and end of the selection are at the very end
// of the input, since moveStart/moveEnd doesn't return what we want
// in those cases
endRange = el.createTextRange();
endRange.collapse(false);
if (textInputRange.compareEndPoints("StartToEnd", endRange) > -1) {
start = end = len;
} else {
start = -textInputRange.moveStart("character", -len);
start += normalizedValue.slice(0, start).split("\n").length - 1;
if (textInputRange.compareEndPoints("EndToEnd", endRange) > -1) {
end = len;
} else {
end = -textInputRange.moveEnd("character", -len);
end += normalizedValue.slice(0, end).split("\n").length - 1;
}
}
}
}
return {
start: start,
end: end
};
}
I want to write a program that (...) creates the directory and a (...) file inside of it
because this is a very common question, here is the code to create multiple levels of directories and than call fopen. I'm using a gnu extension to print the error message with printf.
void rek_mkdir(char *path) {
char *sep = strrchr(path, '/');
if(sep != NULL) {
*sep = 0;
rek_mkdir(path);
*sep = '/';
}
if(mkdir(path, 0777) && errno != EEXIST)
printf("error while trying to create '%s'\n%m\n", path);
}
FILE *fopen_mkdir(char *path, char *mode) {
char *sep = strrchr(path, '/');
if(sep) {
char *path0 = strdup(path);
path0[ sep - path ] = 0;
rek_mkdir(path0);
free(path0);
}
return fopen(path,mode);
}
You need to use : "$@"
(WITH the quotes) or "${@}"
(same, but also telling the shell where the variable name starts and ends).
(and do NOT use : $@
, or "$*"
, or $*
).
ex:
#testscript1:
echo "TestScript1 Arguments:"
for an_arg in "$@" ; do
echo "${an_arg}"
done
echo "nb of args: $#"
./testscript2 "$@" #invokes testscript2 with the same arguments we received
I'm not sure I understood your other requirement ( you want to invoke './testscript2' in single quotes?) so here are 2 wild guesses (changing the last line above) :
'./testscript2' "$@" #only makes sense if "/path/to/testscript2" containes spaces?
./testscript2 '"some thing" "another"' "$var" "$var2" #3 args to testscript2
Please give me the exact thing you are trying to do
edit: after his comment saying he attempts tesscript1 "$1" "$2" "$3" "$4" "$5" "$6" to run : salt 'remote host' cmd.run './testscript2 $1 $2 $3 $4 $5 $6'
You have many levels of intermediate: testscript1 on host 1, needs to run "salt", and give it a string launching "testscrit2" with arguments in quotes...
You could maybe "simplify" by having:
#testscript1
#we receive args, we generate a custom script simulating 'testscript2 "$@"'
theargs="'$1'"
shift
for i in "$@" ; do
theargs="${theargs} '$i'"
done
salt 'remote host' cmd.run "./testscript2 ${theargs}"
if THAt doesn't work, then instead of running "testscript2 ${theargs}", replace THE LAST LINE above by
echo "./testscript2 ${theargs}" >/tmp/runtestscript2.$$ #generate custom script locally ($$ is current pid in bash/sh/...)
scp /tmp/runtestscript2.$$ user@remotehost:/tmp/runtestscript2.$$ #copy it to remotehost
salt 'remotehost' cmd.run "./runtestscript2.$$" #the args are inside the custom script!
ssh user@remotehost "rm /tmp/runtestscript2.$$" #delete the remote one
rm /tmp/runtestscript2.$$ #and the local one
As a kind of simple solution you can use temp TreeMap if you need just a final result:
TreeMap<String, Integer> sortedMap = new TreeMap<String, Integer>();
for (Map.Entry entry : map.entrySet()) {
sortedMap.put((String) entry.getValue(), (Integer)entry.getKey());
}
This will get you strings sorted as keys of sortedMap.
With option context, this is possible without permanently setting use_inf_as_na
. For example:
with pd.option_context('mode.use_inf_as_na', True):
df = df.dropna(subset=['col1', 'col2'], how='all')
Of course it can be set to treat inf
as NaN
permanently with
pd.set_option('use_inf_as_na', True)
For older versions, replace use_inf_as_na
with use_inf_as_null
.
If you're saying you might have different clients as well, there are problems with classic ADO if SET NOCOUNT is not set ON.
One I experience regularly: if a stored procedure executes a number of statements (and thus a number of "xxx rows affected" messages are returned), ADO seems not to handle this and throws the error "Cannot change the ActiveConnection property of a Recordset object which has a Command object as its source."
So I generally advocate setting it ON unless there's a really really good reason not to. you may have found the really really good reason which I need to go and read into more.
I just add numbers to the beginning of file name:
0_normalize.scss
1_tikitaka.scss
main.scss
It works in gulp without any problems.
You should actually return "200 OK" and in the response body include a message about what happened with the posted data. Then it's up to your application to understand the message.
The thing is, HTTP status codes are exactly that - HTTP status codes. And those are meant to have meaning only at the transportation layer, not at the application layer. The application layer should really never even know that HTTP is being used. If you switched your transportation layer from HTTP to Homing Pigeons, it should not affect your application layer in any way.
Let me give you a non-virtual example. Let's say you fall in love with a girl and she loves you back but her family moves to a completely different country. She gives you her new snail-mail address. Naturally, you decide to send her a love letter. So you write your letter, put it into an envelope, write her address on the envelope, put a stamp on it and send it. Now let's consider these scenarios
In short: Returning "200 OK" doesn't mean that the server app has good news for you. It only means that it has some news.
PS: The 422 status code has a meaning only in the context of WebDAV. If you're not working with WebDAV, then 422 has exactly the same standard meaning as any other non-standard code = which is none.
To get instance classname:
type(instance).__name__
or
instance.__class__.__name__
both are the same
You can also write a date inside the parentheses of the Date()
object, like these:
new Date("Month dd, yyyy hh:mm:ss")
new Date("Month dd, yyyy")
new Date(yyyy,mm,dd,hh,mm,ss)
new Date(yyyy,mm,dd)
new Date(milliseconds)
You start a thread which runs the static method SumData
. However, SumData
calls SetTextboxText
which isn't static. Thus you need an instance of your form to call SetTextboxText
.
In Java, 0 is the same as 0.0, and doubles default to 0 (though many advise always setting them explicitly for improved readability).
I have checked and foo.x == 0
and foo.x == 0.0
are both true if foo.x
is zero
Go to installed mysql path and find bin folder,open my.ini and search 3306 after that change 3306 to 3360
You can't do this, since then how could you even compile your tests? The compiler won't take the annotation into account.
There are two general approaches to this
The first is to use reflection to access the methods anyway
The second is to use package-private instead of private, then have your tests in the same package (but in a different module). They will essentially be private to other code, but your tests will still be able to access them.
Of course, if you do black-box testing, you shouldn't be accessing the private members anyway.
My finding is as below. If I compile using the Android Studio UI, and the APK generated, I can't just
adb install <xxx.apk>
It will generate Failure [INSTALL_FAILED_TEST_ONLY]
I need to compile it using the gradle i.e. ./gradlew app:assembleRelease
. Then only the generated apk, then it can only be installed.
This is because the Android Studio UI Compile, only generate test apk for a particular device, while ./gradlew app:assembleRelease
command is the actual apk generation to be installed on all device (and upload to playstore)
No. I guess you were hoping that something like num1 = 20 if someBoolValue
would work, but it doesn't. I think the best way is with the if
statement as you have written it:
if someBoolValue:
num1 = 20
IMPORTANT this answer is valid only for PHP 5, in PHP 7 use built-in cryptographic functions.
Here is simple but secure enough implementation:
Code and examples are here: https://stackoverflow.com/a/19445173/1387163
function search($array, $key, $value)
{
$results = array();
if (is_array($array))
{
if (isset($array[$key]) && $array[$key] == $value)
$results[] = $array;
foreach ($array as $subarray)
$results = array_merge($results, search($subarray, $key, $value));
}
return $results;
}
a full working version for Apache HttpClient 4.1.3 (based on oleg's code above, but it still needed an allow_all_hostname_verifier on my system):
private static HttpClient trustEveryoneSslHttpClient() {
try {
SchemeRegistry registry = new SchemeRegistry();
SSLSocketFactory socketFactory = new SSLSocketFactory(new TrustStrategy() {
public boolean isTrusted(final X509Certificate[] chain, String authType) throws CertificateException {
// Oh, I am easy...
return true;
}
}, org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
registry.register(new Scheme("https", 443, socketFactory));
ThreadSafeClientConnManager mgr = new ThreadSafeClientConnManager(registry);
DefaultHttpClient client = new DefaultHttpClient(mgr, new DefaultHttpClient().getParams());
return client;
} catch (GeneralSecurityException e) {
throw new RuntimeException(e);
}
}
Note I'm re-throwing all exceptions because really, there's not much I can do if any of this fails in a real system!
<button></button>
)<button></button>
(Hint: IE6)Another IE problem when using <button />
:
And while we're talking about IE, it's got a couple of bugs related to the width of buttons. It'll mysteriously add extra padding when you're trying to add styles, meaning you have to add a tiny hack to get things under control.
Why not use order by asc limit 1
and the reverse, order by desc limit 1
?
Better approach may be a polyfill like this
jQuery.fn.load = function(callback){ $(window).on("load", callback) };
With this you can leave the legacy code untouched. If you use webpack be sure to use script-loader.
Do everything suggested by ziesemer.
You may also want to :
No, there is no way to only set the opacity of a border with css.
For example, if you did not know the color, there is no way to only change the opacity of the border by simply using rgba()
.
as @Geoffrey pointed out, with spring security, you need a different approach as described here: Spring Boot Security CORS
GROUP BY DATE_FORMAT(summaryDateTime,'%Y-%m')
Try to use (focusout) instead of (blur)
The iframe always keeps the parent page, you should use this to detect in which page you are in the iframe:
Html code:
<iframe id="iframe" frameborder="0" scrolling="no" onload="resizeIframe(this)" width="100%" src="www.google.com"></iframe>
Js:
function resizeIframe(obj) {
alert(obj.contentWindow.location.pathname);
}
Is the array sorted? If so you could do a binary search. Here is the .NET implementation as well. If the array is sorted then a binary search will improve performance over any iterative solution.
There's also the NVL function
<hr>
is not from struts. It is just an HTML tag.
So, take a look here: http://www.microbion.co.uk/web/vertline.htm This link will give you a couple of tips.
I use inf/-inf as initial values to find minimum/maximum value of a measurement. Lets say that you measure temperature with a sensor and you want to keep track of minimum/maximum temperature. The sensor might provide a valid temperature or might be broken. Pseudocode:
# initial value of the temperature
t = float('nan')
# initial value of minimum temperature, so any measured temp. will be smaller
t_min = float('inf')
# initial value of maximum temperature, so any measured temp. will be bigger
t_max = float('-inf')
while True:
# measure temperature, if sensor is broken t is not changed
t = measure()
# find new minimum temperature
t_min = min(t_min, t)
# find new maximum temperature
t_max = max(t_max, t)
The above code works because inf/-inf/nan are valid for min/max operation, so there is no need to deal with exceptions.
In my tray app, I needed to clean Excel and Word Interops. So This simple method kills processes generically.
This uses a general exception handler, but could be easily split for multiple exceptions like stated in other answers. I may do this if my logging produces alot of false positives (ie can't kill already killed). But so far so guid (work joke).
/// <summary>
/// Kills Processes By Name
/// </summary>
/// <param name="names">List of Process Names</param>
private void killProcesses(List<string> names)
{
var processes = new List<Process>();
foreach (var name in names)
processes.AddRange(Process.GetProcessesByName(name).ToList());
foreach (Process p in processes)
{
try
{
p.Kill();
p.WaitForExit();
}
catch (Exception ex)
{
// Logging
RunProcess.insertFeedback("Clean Processes Failed", ex);
}
}
}
This is how i called it then:
killProcesses((new List<string>() { "winword", "excel" }));
Just adding for easy implementation. You can simply make a form and then make the submit button hidden:
For example:
<form action="submit.php" method="post">
Name : <input type="text" name="test">
<input type="submit" style="display: none;">
</form>
for what DB is the user? look at this example
mysql> create database databasename;
Query OK, 1 row affected (0.00 sec)
mysql> grant all on databasename.* to cmsuser@localhost identified by 'password';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
so to return to you question the "%" operator means all computers in your network.
like aspesa shows I'm also sure that you have to create or update a user. look for all your mysql users:
SELECT user,password,host FROM user;
as soon as you got your user set up you should be able to connect like this:
mysql -h localhost -u gmeier -p
hope it helps

I tried simple destructing technique
TL;DR:
Modern way is to use COC for intellisense-like completion and one or more language servers (LS) for jump-to-definition (and way way more). For even more functionality (but it's not needed for jump-to-definition) you can install one or more debuggers and get a full blown IDE experience.
Quick-start:
~/.vimrc
:
call plug#begin()
Plug 'neoclide/coc.nvim', {'branch': 'release'}
Plug 'puremourning/vimspector'
call plug#end()
" key mappings example
nmap <silent> gd <Plug>(coc-definition)
nmap <silent> gD <Plug>(coc-implementation)
nmap <silent> gr <Plug>(coc-references)
" there's way more, see `:help coc-key-mappings@en'
:source $MYVIMRC | PlugInstall
to reload VIM config and download plug-insvim
and call :CocInstall coc-marketplace
to get easy access to COC extensions:CocList marketplace
and search for language servers, e.g.:python
to find coc-jedi
,php
to find coc-phpls
, etc.install_gadget.py --help
for available debuggers, e.g.:./install_gadget.py --enable-python
,./install_gadget.py --force-enable-php
, etc.You can jump to definition with gd
, to interface implementation with gD
, find all references with gr
. More keybindings in :help coc-key-mappings@en
.
Full answer:
Language server (LS) is a separate standalone application (one for each programming language) that runs in the background and analyses your whole project in real time exposing extra capabilities to your editor (any editor, not only vim
). You get things like:
Communication with language servers takes place via Language Server Protocol (LSP). Both nvim
and vim8
(or higher) support LSP through plug-ins, the most popular being Conquer of Completion (COC).
List of actively developed language servers and their capabilities is available on Lang Server website. Not all of those are provided by COC extensions. If you want to use one of those you can either write a COC extension yourself or install LS manually and use the combo of following VIM plug-ins as alternative to COC:
Communication with debuggers takes place via Debug Adapter Protocol (DAP). The most popular DAP plug-in for VIM is Vimspector.
Language Server Protocol (LSP) was created by Microsoft for Visual Studio Code and released as an open source project with a permissive MIT license (standardized by collaboration with Red Hat and Codenvy). Later on Microsoft released Debug Adapter Protocol (DAP) as well. Any language supported by VSCode is supported in VIM.
I personally recommend using COC + language servers provided by COC extensions + ALE for extra linting (but with LSP support disabled to avoid conflicts with COC) + Vimspector + debuggers provided by Vimspector (called "gadgets") + following VIM plug-ins:
call plug#begin()
Plug 'neoclide/coc.nvim'
Plug 'dense-analysis/ale'
Plug 'puremourning/vimspector'
Plug 'scrooloose/nerdtree'
Plug 'scrooloose/nerdcommenter'
Plug 'sheerun/vim-polyglot'
Plug 'yggdroot/indentline'
Plug 'tpope/vim-surround'
Plug 'kana/vim-textobj-user'
\| Plug 'glts/vim-textobj-comment'
Plug 'janko/vim-test'
Plug 'vim-scripts/vcscommand.vim'
Plug 'mhinz/vim-signify'
call plug#end()
You can google each to see what they do.
Also, pipe character |
separates VIM commands put in one line which makes it perfect to set up plug-in dependencies, i.e. vim-textobj-comment
doesn't work without vim-textobj-user
so if installation of vim-textobj-user
fails the rest of the line isn't executed. Here pipe is escaped with backslash \
because it's in a new line but for VIM it's still a one-liner.
You can always take the CTE, (Common Tabular Expression), approach.
;WITH updateCTE AS
(
SELECT ID, TITLE
FROM HOLD_TABLE
WHERE ID = 101
)
UPDATE updateCTE
SET TITLE = 'TEST';
set your CssClass property in textbox1 to "cupper", then in page content create new css class :
<style type="text/css">.cupper {text-transform:uppercase;}</style>
Then, enjoy it ...
The easiest way i think is as provided by the android support library:
android.support.v4.widget.SwipeRefreshLayout;
once that is imported then you can have your layout defined as follows:
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/refresh"
android:layout_height="match_parent"
android:layout_width="match_parent">
<android.support.v7.widget.RecyclerView
xmlns:recycler_view="http://schemas.android.com/apk/res-auto"
android:id="@android:id/list"
android:theme="@style/Theme.AppCompat.Light"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/button_material_light"
>
</android.support.v7.widget.RecyclerView>
</android.support.v4.widget.SwipeRefreshLayout>
I assume that you use recycler view instead of listview. However, listview still works so you just need to replace recyclerview with listview and update the references in the java code (Fragment).
In your activity fragment, you first implement the interface, SwipeRefreshLayout.OnRefreshListener
:
i,e
public class MySwipeFragment extends Fragment implements SwipeRefreshLayout.OnRefreshListener{
private SwipeRefreshLayout swipeRefreshLayout;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_item, container, false);
swipeRefreshLayout = (SwipeRefreshLayout) view.findViewById(R.id.refresh);
swipeRefreshLayout.setOnRefreshListener(this);
}
@Override
public void onRefresh(){
swipeRefreshLayout.setRefreshing(true);
refreshList();
}
refreshList(){
//do processing to get new data and set your listview's adapter, maybe reinitialise the loaders you may be using or so
//when your data has finished loading, cset the refresh state of the view to false
swipeRefreshLayout.setRefreshing(false);
}
}
Hope this helps the masses
childform = new Child();
childform.Show(this);
In event childform load
this.CenterToParent();
You can use a simple regex like this:
public static string StripHTML(string input)
{
return Regex.Replace(input, "<.*?>", String.Empty);
}
Be aware that this solution has its own flaw. See Remove HTML tags in String for more information (especially the comments of @mehaase)
Another solution would be to use the HTML Agility Pack.
You can find an example using the library here: HTML agility pack - removing unwanted tags without removing content?
As mentionned in this post pandas: how to store a list in a dataframe?; the dtypes in the dataframe may influence the results, as well as calling a dataframe or not to be assigned to.
These steps worked for me:using git://
instead of https://
Here is one quick suggestion for creating variable names. If you want the variable not to conflict when being used in FireFox, do not use the variable name "_content" as this variable name is already being used by the browser. I found this out the hard way and had to change all of the places I used the variable "_content" in a large JavaScript application.
For multiple files input using lodash or underscore:
.directive("fileread", [function () {
return {
scope: {
fileread: "="
},
link: function (scope, element, attributes) {
element.bind("change", function (changeEvent) {
return _.map(changeEvent.target.files, function(file){
scope.fileread = [];
var reader = new FileReader();
reader.onload = function (loadEvent) {
scope.$apply(function () {
scope.fileread.push(loadEvent.target.result);
});
}
reader.readAsDataURL(file);
});
});
}
}
}]);
Size detects duplicates, it will return the number of unique values
const set1 = new Set([1, 2, 3, 4, 5, 5, 5, 6]);
console.log(set1.size);
// expected output: 6
set "PathName=X:\Web Content Mgmt\Completed Filtering\2013_Folder"
set "comd=dir /b /s *.zip"
cd /d "%PathName%"
%comd%
If you have a for loop such as the one below.
Change @item.StartDate to @item.StartDate.Value.ToShortDateString()
This will remove the time just in case you can't annotate your property in the model like in my case.
<table>
<tr>
<th>Type</th>
<th>Start Date</th>
</tr>
@foreach (var item in Model.TestList) {
<tr>
<td>@item.TypeName</td>
<td>@item.StartDate.Value.ToShortDateString()</td>
</tr>

Just like @Thomas said, the element you want to change must implement INotifyPropertyChanged. But, datasource is also important. It has to be BindingList, which you can create easily from List.
Here is my example - data source is at first DataTable, which I transfer to List and then create BindingList. Then I create BindingSource and use BindingList as DataSource from BindingSource. At last, DataSource from DataGridView uses this BindingSource.
sp_Select_PersonTableAdapter adapter = new sp_Select_PersonTableAdapter();
DataTable tbl = new DataTable();
tbl.Merge(adapter.GetData());
List<Person> list = tbl.AsEnumerable().Select(x => new Person
{
Id = (Int32) (x["Id"]),
Ime = (string) (x["Name"] ?? ""),
Priimek = (string) (x["LastName"] ?? "")
}).ToList();
BindingList<Person> bindingList = new BindingList<Person>(list);
BindingSource bindingSource = new BindingSource();
bindingSource.DataSource = bindingList;
dgvPerson.DataSource = bindingSource;
What is also very important: each class's member setter must call OnPropertyChanged(). Without that, it won't work. So, my class looks like this:
public class Person : INotifyPropertyChanged
{
private int _id;
private string _name;
private string _lastName;
public int Id
{
get { return _id; }
set
{
if (value != _id)
{
_id = value;
OnPropertyChanged();
}
}
}
public string Name
{
get { return _name; }
set
{
if (value != _name)
{
_name = value;
OnPropertyChanged();
}
}
}
public string LastName
{
get { return _lastName; }
set
{
if (value != _lastName)
{
_lastName= value;
OnPropertyChanged();
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
[NotifyPropertyChangedInvocator]
protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
{
PropertyChangedEventHandler handler = PropertyChanged;
if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName));
}
}

If you join the facilities table twice you will get what you are after:
select u.*
from room u
JOIN facilities_r fu1 on fu1.id_uc = u.id_uc and fu1.id_fu = '4'
JOIN facilities_r fu2 on fu2.id_uc = u.id_uc and fu2.id_fu = '3'
where 1 and vizibility='1'
group by id_uc
order by u_premium desc, id_uc desc
You need to extract the initilization of time() out of the for loop.
Here is an example that will output in the windows console expected (ahah) random number.
#include <iostream>
#include <windows.h>
#include "time.h"
int main(int argc, char*argv[])
{
srand ( time(NULL) );
for (int t = 0; t < 10; t++)
{
int random_x;
random_x = rand() % 100;
std::cout << "\nRandom X = " << random_x << std::endl;
}
Sleep(50000);
return 0;
}
Hope this helps someone in the future. My problem was that I was following the same tutorial as the OP to enable global CORS. However, I also set an Action specific CORS rule in my AccountController.cs file:
[EnableCors(origins: "", headers: "*", methods: "*")]
and was getting errors about the origin cannot be null or empty string. BUT the error was happening in the Global.asax.cs file of all places. Solution is to change it to:
[EnableCors(origins: "*", headers: "*", methods: "*")]
notice the * in the origins? Missing that was what was causing the error in the Global.asax.cs file.
Hope this helps someone.

In bash version 4 associative arrays were introduced.
declare -A arr
arr["key1"]=val1
arr+=( ["key2"]=val2 ["key3"]=val3 )
The arr array now contains the three key value pairs. Bash is fairly limited what you can do with them though, no sorting or popping etc.
for key in ${!arr[@]}; do
echo ${key} ${arr[${key}]}
done
Will loop over all key values and echo them out.
Note: Bash 4 does not come with Mac OS X because of its GPLv3 license; you have to download and install it. For more on that see here
I looked to MS to find the answers. The first solution assumes the user account running the application process has access to the shared folder or drive (Same domain). Make sure your DNS is resolved or try using IP address. Simply do the following:
DirectoryInfo di = new DirectoryInfo(PATH);
var files = di.EnumerateFiles("*.*", SearchOption.AllDirectories);
If you want across different domains .NET 2.0 with credentials follow this model:
WebRequest req = FileWebRequest.Create(new Uri(@"\\<server Name>\Dir\test.txt"));
req.Credentials = new NetworkCredential(@"<Domain>\<User>", "<Password>");
req.PreAuthenticate = true;
WebResponse d = req.GetResponse();
FileStream fs = File.Create("test.txt");
// here you can check that the cast was successful if you want.
fs = d.GetResponseStream() as FileStream;
fs.Close();
Errors: "Bad encrypt / decrypt" "gitencrypt_smudge: FAILURE: openssl error decrypting file"
There are various error strings that are thrown from openssl, depending on respective versions, and scenarios. Below is the checklist I use in case of openssl related issues:
Ensure that openssl versions (used to encrypt/decrypt), are compatible. For eg. the hash used in openssl changed at version 1.1.0 from MD5 to SHA256. This produces a different key from the same password. Fix: add "-md md5" in 1.1.0 to decrypt data from lower versions, and add "-md sha256 in lower versions to decrypt data from 1.1.0
Ensure that there is a single openssl version installed in your machine. In case there are multiple versions installed simultaneously (in my machine, these were installed :- 'LibreSSL 2.6.5' and 'openssl 1.1.1d'), make the sure that only the desired one appears in your PATH variable.

Here you can find explanation which statements from standard and which GNU extensions above code uses.
(Maybe a bit not in scope of the question, since question is not about failure on type mismatch, but anyway, leaving it here).
It's just a method on your form, you can call it just like any other method. You just have to create an EventArgs object to pass to it, (and pass it the handle of the button as sender
)
There may be a simpler option, but you can use VLOOKUP to check if a value appears in a list (and VLOOKUP is a powerful formula to get to grips with anyway).
So for A1, you can set a conditional format using the following formula:
=NOT(ISNA(VLOOKUP(A1,$B:$B,1,FALSE)))
Copy and Paste Special > Formats to copy that conditional format to the other cells in column A.
What the above formula is doing:
From the Rails api on PartialRender:
Rendering the default case
If you're not going to be using any of the options like collections or layouts, you can also use the short-hand defaults of render to render partials.
Examples:
# Instead of <%= render partial: "account" %>
<%= render "account" %>
# Instead of <%= render partial: "account", locals: { account: @buyer } %>
<%= render "account", account: @buyer %>
# @account.to_partial_path returns 'accounts/account', so it can be used to replace:
# <%= render partial: "accounts/account", locals: { account: @account} %>
<%= render @account %>
# @posts is an array of Post instances, so every post record returns 'posts/post' on `to_partial_path`,
# that's why we can replace:
# <%= render partial: "posts/post", collection: @posts %>
<%= render @posts %>
So, you can use pass a local variable size
to render as follows:
<%= render @users, size: 50 %>
and then use it in the _user.html.erb
partial:
<li>
<%= gravatar_for user, size: size %>
<%= link_to user.name, user %>
</li>
Note that size: size
is equivalent to :size => size
.
you make the use of the HTML Helper and have
@using(Html.BeginForm())
{
Username: <input type="text" name="username" /> <br />
Password: <input type="text" name="password" /> <br />
<input type="submit" value="Login">
<input type="submit" value="Create Account"/>
}
or use the Url helper
<form method="post" action="@Url.Action("MyAction", "MyController")" >
Html.BeginForm
has several (13) overrides where you can specify more information, for example, a normal use when uploading files is using:
@using(Html.BeginForm("myaction", "mycontroller", FormMethod.Post, new {enctype = "multipart/form-data"}))
{
< ... >
}
If you don't specify any arguments, the Html.BeginForm()
will create a POST
form that points to your current controller and current action. As an example, let's say you have a controller called Posts
and an action called Delete
public ActionResult Delete(int id)
{
var model = db.GetPostById(id);
return View(model);
}
[HttpPost]
public ActionResult Delete(int id)
{
var model = db.GetPostById(id);
if(model != null)
db.DeletePost(id);
return RedirectToView("Index");
}
and your html page would be something like:
<h2>Are you sure you want to delete?</h2>
<p>The Post named <strong>@Model.Title</strong> will be deleted.</p>
@using(Html.BeginForm())
{
<input type="submit" class="btn btn-danger" value="Delete Post"/>
<text>or</text>
@Url.ActionLink("go to list", "Index")
}
My answer is similar to this one on ServerFault.com.
If you want to be more conservative than granting "all privileges", you might want to try something more like these.
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO some_user_;
GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA public TO some_user_;
The use of public
there refers to the name of the default schema created for every new database/catalog. Replace with your own name if you created a schema.
To access a schema at all, for any action, the user must be granted "usage" rights. Before a user can select, insert, update, or delete, a user must first be granted "usage" to a schema.
You will not notice this requirement when first using Postgres. By default every database has a first schema named public
. And every user by default has been automatically been granted "usage" rights to that particular schema. When adding additional schema, then you must explicitly grant usage rights.
GRANT USAGE ON SCHEMA some_schema_ TO some_user_ ;
Excerpt from the Postgres doc:
For schemas, allows access to objects contained in the specified schema (assuming that the objects' own privilege requirements are also met). Essentially this allows the grantee to "look up" objects within the schema. Without this permission, it is still possible to see the object names, e.g. by querying the system tables. Also, after revoking this permission, existing backends might have statements that have previously performed this lookup, so this is not a completely secure way to prevent object access.
For more discussion see the Question, What GRANT USAGE ON SCHEMA exactly do?. Pay special attention to the Answer by Postgres expert Craig Ringer.
These commands only affect existing objects. Tables and such you create in the future get default privileges until you re-execute those lines above. See the other answer by Erwin Brandstetter to change the defaults thereby affecting future objects.

Lots of ways to do this. The most reliable is find.
Dim rLastCell As Range
Set rLastCell = ws.Cells.Find(What:="*", After:=ws.Cells(1, 1), LookIn:=xlFormulas, LookAt:= _
xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlPrevious, MatchCase:=False)
MsgBox ("The last used column is: " & rLastCell.Column)
If you want to find the last column used in a particular row you can use:
Dim lColumn As Long
lColumn = ws.Cells(1, Columns.Count).End(xlToLeft).Column
Using used range (less reliable):
Dim lColumn As Long
lColumn = ws.UsedRange.Columns.Count
Using used range wont work if you have no data in column A. See here for another issue with used range:
See Here regarding resetting used range.
This post was helpful for my project hence I thought of sharing my experience as well. The essential thing to note is that the POST request is possible only with a form. I had a similar requirement as I was trying to render a page with ejs. I needed to render a navigation with a list of items that would essentially be hyperlinks and when user selects any one of them, the server responds with appropriate information.
so I basically created each of the navigation items as a form using a loop as follows:
<ul>_x000D_
begin loop..._x000D_
<li>_x000D_
<form action="/" method="post">_x000D_
<input type="hidden" name="country" value="India"/>_x000D_
<button type="submit" name="button">India</button>_x000D_
</form> _x000D_
</li>_x000D_
end loop._x000D_
</ul>
_x000D_
what it did is to create a form with hidden input with a value assigned same as the text on the button. So the end user will see only text from the button and when clicked, will send a post request to the server.
Note that the value parameter of the input box and the Button text are exactly same and were values passed using ejs that I have not shown in this example above to keep the code simple.
here is a screen shot of the navigation... enter image description here

foreach(ListItem listItem in lblMultiSelect.Items)
{
if (listItem.Selected)
{
var val = listItem.Value;
var txt = listItem.Text;

For docker-compose version 2 file format, you can build and tag an image for one service and then use that same built image for another service.
For my case, I want to set up an elasticsearch cluster with 2 nodes, they both need to use the same image, but configured to run differently. I also want to build my own custom elasticsearch image from my own Dockerfile. So this is what I did (docker-compose.yml
):
version: '2'
services:
es-master:
build: ./elasticsearch
image: porter/elasticsearch
ports:
- "9200:9200"
container_name: es_master
es-node:
image: porter/elasticsearch
depends_on:
- es-master
ports:
- "9200"
command: elasticsearch --discovery.zen.ping.unicast.hosts=es_master
You can see that in the first service definition es-master
, I use the build
option to build an image from the Dockerfile in ./elasticsearch
. I tag the image with the name porter/elasticsearch
with the image
option.
Then, I reference this built image in the es-node
service definition with the image
option, and also use a depends_on
to make sure the other container es-master
is built and run first.
The problem with "converting" arbitrary Unicode to ASCII is that the meaning of a character is culture-dependent. For example, “ß” to a German-speaking person should be converted to "ss" while an English-speaker would probably convert it to “B”.
Add to that the fact that Unicode has multiple code points for the same glyphs.
The upshot is that the only way to do this is create a massive table with each Unicode character and the ASCII character you want to convert it to. You can take a shortcut by normalizing characters with accents to normalization form KD, but not all characters normalize to ASCII. In addition, Unicode does not define which parts of a glyph are "accents".
Here is a tiny excerpt from an app that does this:
switch (c)
{
case 'A':
case '\u00C0': // À LATIN CAPITAL LETTER A WITH GRAVE
case '\u00C1': // Á LATIN CAPITAL LETTER A WITH ACUTE
case '\u00C2': // Â LATIN CAPITAL LETTER A WITH CIRCUMFLEX
// and so on for about 20 lines...
return "A";
break;
case '\u00C6':// Æ LATIN CAPITAL LIGATURE AE
return "AE";
break;
// And so on for pages...
}
If you are on Python3 you can also use the library PILasOPENCV which works in Python 2 and 3. Function api calls are the same as in PIL or pillow but internally it works with OpenCV and numpy to load, save and manipulate images. Have a look at https://github.com/bunkahle/PILasOPENCV or install it with pip install PILasOPENCV. Not all PIL functions have been simulated but the most common functions work.
I've an object (basically a VO) in Java and I don't know its type. I need to get values which are not null in that object.
Maybe you don't necessary need reflection for that -- here is a plain OO design that might solve your problem:
Validation
which expose a method validate
which checks the fields and return whatever is appropriate. Validation
and check that easily.I guess that you need the field that are null to display an error message in a generic way, so that should be enough. Let me know if this doesn't work for you for some reason.
My application was hanging on startup when I used Peter Stulinski & Dave Gordon's code samples with EF 6.0. I changed:
var roleManager = new RoleManager<Microsoft.AspNet.Identity.EntityFramework.IdentityRole>(new RoleStore<IdentityRole>(new ApplicationDbContext()));
to
var roleManager = new RoleManager<Microsoft.AspNet.Identity.EntityFramework.IdentityRole>(new RoleStore<IdentityRole>(**context**));
Which makes sense when in the seed method you don't want instantiate another instance of the ApplicationDBContext
. This might have been compounded by the fact that I had Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer());
in the constructor of ApplicationDbContext
@Naftule - with "defiant.js", it is possible to query a JSON structure with XPath expressions. Check out this evaluator to get an idea of how it works:

This will open for reading and writing, creating the file if necessary.
FILE *fp = fopen("scores.dat", "ab+");
If you want to read it and then write a new version from scratch, then do it as two steps.
FILE *fp = fopen("scores.dat", "rb");
if (fp) {
read_scores(fp);
}
// Later...
// truncates the file
FILE *fp = fopen("scores.dat", "wb");
if (!fp)

For Angular 2+ to get the offset of the current element (this.el.nativeElement is equvalent of $(this) in jquery):
export class MyComponent implements OnInit {

//--------------------------------------------------------------------------
let offset = this.el.nativeElement.getBoundingClientRect().top;
//--------------------------------------------------------------------------
console.log(offset);
}

The main question for me would be, what are you actually trying to find out? Are you trying to find out, when a certain set of changes was introduced in that file?
You can use git blame
for this, it will anotate each line with a SHA1 and a date when it was changed. git blame
can also tell you when a certain line was deleted or where it was moved if you are interested in that.
If you are trying to find out, when a certain bug was introduced, git bisect
is a very powerfull tool. git bisect
will do a binary search on your history. You can use git bisect start
to start bisecting, then git bisect bad
to mark a commit where the bug is present and git bisect good
to mark a commit which does not have the bug. git will checkout a commit between the two and ask you if it is good or bad. You can usually find the faulty commit within a few steps.
Since I have used git, I hardly ever found the need to manually look through patch histories to find something, since most often git offers me a way to actually look for the information I need.
If you try to think less of how to do a certain workflow, but more in what information you need, you will probably many workflows which (in my opinion) are much more simple and faster.
That didn't really work in my case - i.e. in order to overwrite hosts file you have to follow it's directions, ie:
./emulator -avd myEmulatorName -partition-size 280
and then in other term window (pushing new hosts file /tmp/hosts):
./adb remount
./adb push /tmp/hosts /system/etc
In my case, there was a problem with MySQL reference. Somehow, I could list three versions of it under the list of all available references; for .net 2.0, .net 4.0 and .net 4.5. I followed process 1 through 6 above and it worked for me.
You can do this using generic SQL with group by
:
SELECT C.Content_ID, C.Content_Title, MAX(M.Media_Id)
FROM tbl_Contents C LEFT JOIN
tbl_Media M
ON M.Content_Id = C.Content_Id
GROUP BY C.Content_ID, C.Content_Title
ORDER BY MAX(C.Content_DatePublished) ASC;
Or with a correlated subquery:
SELECT C.Content_ID, C.Contt_Title,
(SELECT M.Media_Id
FROM tbl_Media M
WHERE M.Content_Id = C.Content_Id
ORDER BY M.MEDIA_ID DESC
LIMIT 1
) as Media_Id
FROM tbl_Contents C
ORDER BY C.Content_DatePublished ASC;
Of course, the syntax for limit 1
varies between databases. Could be top
. Or rownum = 1
. Or fetch first 1 rows
. Or something like that.
It would be beneficial to verify the form's data before sending it via POST. You should create a JavaScript function to check the form for errors and then send the form. This would prevent the data from being sent over and over again, possibly slowing the browser and using transfer volume on the server.
Edit:
If security is a concern, performing an AJAX request to verify the data would be the best way. The response from the AJAX request would determine whether the form should be submitted.
Try setuser. Example
declare @schema nvarchar (256)
set @schema=(
select top 1 TABLE_SCHEMA
from INFORMATION_SCHEMA.TABLES
where TABLE_NAME='MyTable'
)
if @schema<>'dbo' setuser @schema
I don't think it is necessary to "host" the content using the way from the accepted answer. It is too complicated for a normal user with limited developing skills.
Google actually has provided hosting feature without using Drive SDK/API, what you need is just few clicks. Check this out:
http://support.google.com/drive/bin/answer.py?hl=en&answer=2881970
It is the same to the answer of user1557669. However, in step 4, the URL is not correct, it is like:
https://drive.google.com/#folders/...
To get the correct host URL. Right click on the html file (you have to finish 1-3 steps first and put the html in the public shared folder), and select "Details" from the context menu. You will find the hosting URL right close to the bottom of the details panel. It should look like:
https://googledrive.com/host/.../abc.html
Then you can share the link to anyone. Happy sharing.
