What you have here is a non-local variable (https://en.wikipedia.org/wiki/Non-local_variable), i.e. you access a local variable in a method an anonymous class.
Local variables of the method are kept on the stack and lost as soon as the method ends, however even after the method ends, the local inner class object is still alive on the heap and will need to access this variable (here, when an action is performed).
I would suggest two workarounds :
Either you make your own class that implements actionlistenner
and takes as constructor argument, your variable and keeps it as an class attribute. Therefore you would only access this variable within the same object.
Or (and this is probably the best solution) just qualify a copy of the variable final
to access it in the inner scope as the error suggests to make it a constant:
This would suit your case since you are not modifying the value of the variable.
... What about using Apache's FileFilters from:
org.apache.commons.io
?
just like:
import org.apache.commons.io.filefilter.FileFileFilter;
import org.apache.commons.io.filefilter.WildcardFileFilter;
...
File dir = new File(".");
String[] filters = { "*.txt"};
IOFileFilter wildCardFilter = new WildcardFileFilter(filters, IOCase.INSENSITIVE);
String[] files = dir.list( wildCardFilter );
for ( int i = 0; i < files.length; i++ ) {
System.out.println(files[i]);
}
The following code implements a default context menu known from Windows

I believe the action name is "workbench.action.quickOpen".
I like to use Log.d(TAG, some string, often a String.format ()).
TAG is always the class name
Transform Log.d(TAG, --> Logd( in the text of your class
private void Logd(String str){
if (MainClass.debug) Log.d(className, str);
}
In this way when you are ready to make a release version, set MainClass.debug to false!
I really only use read with "while" and a do loop:
echo "This is NOT a test." | while read -r a b c theRest; do
echo "$a" "$b" "$theRest"; done
This is a test.
For what it's worth, I have seen the recommendation to always use -r with the read command in bash.

make a file classAusiliaria.h
and in there provide your method signatures.
Now instead of including the .c file include this .h file.
Usually i prefer like below in swift 3, because i can add file name and create a file easily
let fileManager = FileManager.default
if let documentsURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first {
let databasePath = documentsURL.appendingPathComponent("db.sqlite3").path
print("directory path:", documentsURL.path)
print("database path:", databasePath)
if !fileManager.fileExists(atPath: databasePath) {
fileManager.createFile(atPath: databasePath, contents: nil, attributes: nil)
}
}
Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:
type: "GET",
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
withCredentials: true
},
success: function (data) {
alert(data);
});
Most of the solutions consider that the lists do not have duplicates. In case your lists do have duplicates you can try this:
def isSubList(subList,mlist):
uniqueElements=set(subList)
for e in uniqueElements:
if subList.count(e) > mlist.count(e):
return False
# It is sublist
return True
It ensures the sublist never has different elements than list or a greater amount of a common element.
lst=[1,2,2,3,4]
sl1=[2,2,3]
sl2=[2,2,2]
sl3=[2,5]
print(isSubList(sl1,lst)) # True
print(isSubList(sl2,lst)) # False
print(isSubList(sl3,lst)) # False
Try this
([A-Z])([A-Z]+)\b
$1\L$2
Make sure case sensitivity is on (Alt + C)
Above answers have enough description for the asked question.
Adding to that, Tensorflow has optimised the operation of applying the activation function then calculating cost using its own activation followed by cost functions. Hence it is a good practice to use: tf.nn.softmax_cross_entropy()
over tf.nn.softmax(); tf.nn.cross_entropy()
You can find prominent difference between them in a resource intensive model.
You can use
<li ng-repeat="(name, age) in items">{{name}}: {{age}}</li>
See ngRepeat documentation. Example: http://jsfiddle.net/WRtqV/1/
The answer by ganeshragav is correct, but it is also useful to know that you can use:
firewall-cmd --permanent --zone=public --add-port=2888/tcp
but if is a known service, you can use:
firewall-cmd --permanent --zone=public --add-service=http
and then reload the firewall
firewall-cmd --reload
[ Answer modified to reflect Martin Peter's comment, original answer had --permanent
at end of command line ]
Just to document if someone has the same problem...
In my situation I've been using :uuid
fields, and the above answers does not work to my case, because rails 5 are creating a column using :bigint
instead :uuid
:
add_reference :uploads, :user, index: true, type: :uuid
Reference: Active Record Postgresql UUID
Using the chronic gem:
class MyModel < ActiveRecord::Base
validate :valid_date?
def valid_date?
unless Chronic.parse(from_date)
errors.add(:from_date, "is missing or invalid")
end
end
end
# file? will only return true for files
File.file?(filename)
and
# Will also return true for directories - watch out!
File.exist?(filename)
The above methods are useful but they are not full-proof because it will give error if time is between 12:00 AM/PM and 01:00 AM/PM . It will return the "No Go" in-spite of being in between the timing . Here is the code for the same:
$time = '2019-03-27 12:00 PM';
$date_one = $time;
$date_one = strtotime($date_one);
$date_one = strtotime("+60 minutes", $date_one);
$date_one = date('Y-m-d h:i A', $date_one);
$date_ten = strtotime($time);
$date_ten = strtotime("-12 minutes", $date_ten);
$date_ten = date('Y-m-d h:i A', $date_ten);
$paymentDate='2019-03-27 12:45 AM';
$contractDateBegin = date('Y-m-d h:i A', strtotime($date_ten));
$contractDateEnd = date('Y-m-d h:i A', strtotime($date_one));
echo $paymentDate;
echo "---------------";
echo $contractDateBegin;
echo "---------------";
echo $contractDateEnd;
echo "---------------";
$contractDateEnd='2019-03-27 01:45 AM';
if($paymentDate > $contractDateBegin && $paymentDate < $contractDateEnd)
{
echo "is between";
}
else
{
echo "NO GO!";
}
Here you will get output "NO Go"
because 12:45 > 01:45
.
To get proper output date in between, make sure that for "AM"
values from 01:00 AM
to 12:00 AM
will get converted to the 24-hour format. This little trick helped me.
Try:
Iterator<Map.Entry<String,String>> iter = testMap.entrySet().iterator();
while (iter.hasNext()) {
Map.Entry<String,String> entry = iter.next();
if("Sample".equalsIgnoreCase(entry.getValue())){
iter.remove();
}
}
With Java 1.8 and onwards you can do the above in just one line:
testMap.entrySet().removeIf(entry -> "Sample".equalsIgnoreCase(entry.getValue()));
There are a few different ways of doing this. I prefer using apply
, since it's easily extendable:
##Generate some data
dd = data.frame(a = 1:4, b= 1:0, c=0:3)
##Go through each row and determine if a value is zero
row_sub = apply(dd, 1, function(row) all(row !=0 ))
##Subset as usual
dd[row_sub,]
This error also occurs if you are trying to write a unit test case in angular using jasmine.
The basic concept of this error is to import FormsModule
. Thus, in the file for unit tests, we add imports Section and place FormsModule in that file under
TestBed.configureTestingModule
For eg:
TestBed.configureTestingModule({
declarations: [ XYZComponent ],
**imports: [FormsModule]**,
}).compileComponents();
A nested object (child) inside another object (parent) cannot get data directly from its parent.
Have a look on this:
var main = {
name : "main object",
child : {
name : "child object"
}
};
If you ask the main object what its child name is (main.child.name
) you will get it.
Instead you cannot do it vice versa because the child doesn't know who its parent is.
(You can get main.name
but you won't get main.child.parent.name
).
By the way, a function could be useful to solve this clue.
Let's extend the code above:
var main = {
name : "main object",
child : {
name : "child object"
},
init : function() {
this.child.parent = this;
delete this.init;
return this;
}
}.init();
Inside the init
function you can get the parent object simply calling this
.
So we define the parent
property directly inside the child
object.
Then (optionally) we can remove the init
method.
Finally we give the main object back as output from the init
function.
If you try to get main.child.parent.name
now you will get it right.
It is a little bit tricky but it works fine.
It is advised to load your scripts at the bottom of your <body>
block to speed up the page load, like this:
<body>
<!-- your content -->
<!-- your scripts -->
<script src=".."></script>
</body>
</html>
extension String {
func substring(from:String) -> String
{
let searchingString = from
let rangeOfSearchingString = self.range(of: searchingString)!
let indexOfSearchingString: Int = self.distance(from: self.startIndex, to: rangeOfSearchingString.upperBound )
let trimmedString = self.substring(start: indexOfSearchingString , end: self.count)
return trimmedString
}
}
Yet another TL;DR
Iterator on list: next()
returns the next element of the list
Iterator generator: next()
will compute the next element on the fly (execute code)
You can see the yield/generator as a way to manually run the control flow from outside (like continue loop one step), by calling next
, however complex the flow.
Note: The generator is NOT a normal function. It remembers the previous state like local variables (stack). See other answers or articles for detailed explanation. The generator can only be iterated on once. You could do without yield
, but it would not be as nice, so it can be considered 'very nice' language sugar.
What I need is to use Docker with MariaDb on different port /3301/ on my Ubuntu machine because I already had MySql installed and running on 3306.
To do this after half day searching did it using:
docker run -it -d -p 3301:3306 -v ~/mdbdata/mariaDb:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root --name mariaDb mariadb
This pulls the image with latest MariaDb, creates container called mariaDb, and run mysql on port 3301. All data of which is located in home directory in /mdbdata/mariaDb.
To login in mysql after that can use:
mysql -u root -proot -h 127.0.0.1 -P3301
Used sources are:

In addition to the hotkey, if you right click in the gutter where you see the +/-, there is a context menu item 'Folding.' Opening the submenu associated with this, you can see a 'Collapse All' item. this will also do what you wish.
Yes, the first function has no relationship with an object instance of that constructor function, you can consider it like a 'static method'.
In JavaScript functions are first-class objects, that means you can treat them just like any object, in this case, you are only adding a property to the function object.
The second function, as you are extending the constructor function prototype, it will be available to all the object instances created with the new
keyword, and the context within that function (the this
keyword) will refer to the actual object instance where you call it.
Consider this example:
// constructor function
function MyClass () {
var privateVariable; // private member only available within the constructor fn
this.privilegedMethod = function () { // it can access private members
//..
};
}
// A 'static method', it's just like a normal function
// it has no relation with any 'MyClass' object instance
MyClass.staticMethod = function () {};
MyClass.prototype.publicMethod = function () {
// the 'this' keyword refers to the object instance
// you can access only 'privileged' and 'public' members
};
var myObj = new MyClass(); // new object instance
myObj.publicMethod();
MyClass.staticMethod();
It was a firewall issue. There was a hardware firewall that was blocking access to almost all ports. (Turning off software firewall / SELinux bla bla had no effect)
Then I scanned the open ports and used the port that was open.
If you are facing the same problem, Run the following command
sudo nmap -T Aggressive -A -v 127.0.0.1 -p 1-65000
It will scan for all the open ports on your system. Any port that is open can be accessed from outside.

require(reshape2)
T <- melt(df, id = c("A"))
T <- dcast(T, A ~ variable, sum)
I am not certain the exact advantages over aggregate.

The ascii values of the:
Up key - 224 72
Down key - 224 80
Left key - 224 75
Right key - 224 77
Each of these has two integer values for ascii value, because they are special keys, as opposed to the code for $, which is simply 36. These 2 byte special keys usually have the first digit as either 224, or 0. this can be found with the F# in windows, or the delete key.
EDIT : This may actually be unicode looking back, but they do work.
Open an elevated Command Prompt (run cmd as administrator). query your registry for available TT fonts to the console by:
REG query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont"
You'll see an output like :
0 REG_SZ Lucida Console
00 REG_SZ Consolas
936 REG_SZ *???
932 REG_SZ *MS ????
Now we need to add a TT font that supports the characters you need like Courier New, we do this by adding zeros to the string name, so in this case the next one would be "000" :
REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont" /v 000 /t REG_SZ /d "Courier New"
Now we implement UTF-8 support:
REG ADD HKCU\Console /v CodePage /t REG_DWORD /d 65001 /f
Set default font to "Courier New":
REG ADD HKCU\Console /v FaceName /t REG_SZ /d "Courier New" /f
Set font size to 20 :
REG ADD HKCU\Console /v FontSize /t REG_DWORD /d 20 /f
Enable quick edit if you like :
REG ADD HKCU\Console /v QuickEdit /t REG_DWORD /d 1 /f
First do a loop using a filter that will return only unique teams, and then a nested loop that returns all players per current team:

var indexedTeams = [];
// this will reset the list of indexed teams each time the list is rendered again
$scope.playersToFilter = function() {

if (teamIsNew) {
indexedTeams.push(player.team);
}

For users that use @app.route it is better to use the key-argument endpoint
rather then chaning the value of __name__
like Roei Bahumi stated. Taking his example will be:
@app.route("/path1", endpoint='func1')
@exception_handler
def func1():
pass
@app.route("/path2", endpoint='func2')
@exception_handler
def func2():
pass

For this case, border-box would also suffice:

box-sizing: border-box
height: 100%
padding-top: $body_padding
Building on Jon Skeet's reply, there are times when you want to invoke a delegate and wait for its execution to complete before the current thread continues. In those cases the Invoke call is what you want.
In multi-threading applications, you may not want a thread to wait on a delegate to finish execution, especially if that delegate performs I/O (which could make the delegate and your thread block).
In those cases the BeginInvoke would be useful. By calling it, you're telling the delegate to start but then your thread is free to do other things in parallel with the delegate.
Using BeginInvoke increases the complexity of your code but there are times when the improved performance is worth the complexity.
Give a try to return bootstrap alert message, this worked for me
return Content("<div class='alert alert-success'><a class='close' data-dismiss='alert'>

you can use

Assuming you're referring to this plugin, your code should be:
// To Store
$(function() {
$.session.set("myVar", "value");
});
// To Read
$(function() {
alert($.session.get("myVar"));
});
Before using a plugin, remember to read its documentation in order to learn how to use it. In this case, an usage example can be found in the README.markdown
file, which is displayed on the project page.
This unfortunately breaks other things. Here is the fix I found on another site that seemed to work for me:
I'd say leave the X-UA-Compatible
as "IE=8"
and add the following code to the bottom of your master page:
<script language="javascript">
/* IE11 Fix for SP2010 */
if (typeof(UserAgentInfo) != 'undefined' && !window.addEventListener)
{
UserAgentInfo.strBrowser=1;
}
</script>
This fixes a bug in core.js
which incorrectly calculates that sets UserAgentInfo.strBrowse=3
for IE11 and thus supporting addEventListener
. I'm not entirely sure on the details other than that but the combination of keeping IE=8 and using this script is working for me. Fingers crossed until I find the next IE11/SharePoint "bug"!
Worth knowing:
If you are running an ENTRYPOINT script ... the script will work with the shebang
#!/bin/bash -x
But will stop the container from stopping with
#!/bin/bash -xe
I had this error occur for a different reason.
I created a template for save/cancel buttons that I wanted to appear at top and bottom of the page. It worked at first when I had my template defined inside of a <script type="text/html"> element.... but then I heard you could optionally create a template out of an ordinary DIV element instead.
(This worked better for me since I was using ASP.NET MVC and none of my @variableName Razor syntax was being executed at runtime from inside of the script element. So by changing to a DIV instead, I could still have the MVC Razor engine generate HTML inside my KnockoutJs template when the page loads.)
After I changed my template to use a DIV instead of a SCRIPT element, my code looked like this.... which worked fine on IE10. However, later when I tested it on IE8, it threw that....
"You cannot apply bindings multiple times to the same element" error.....
HTML
<div id="mainKnockoutDiv" class="measurementsDivContents hourlyMeasurements">
<div id="saveButtons_template" style="display: none;">
... my template content here ...
</div>
<!--ko template: { name: 'saveButtons_template' } -->
<!--/ko-->
Some_HTML_content_here....
<!--ko template: { name: 'saveButtons_template' } -->
<!--/ko-->
</div>
JavaScript
ko.applyBindings(viewModel, document.getElementById('mainKnockoutDiv'));
THE SOLUTION:
All I had to do was move my saveButtons_template DIV down to the bottom, so that it was outside of the mainKnockoutDiv. This solved the problem for me.
I suppose KnockoutJs was trying to bind my template DIV multiple times since it was located inside the applyBindings target area... and was not using the SCRIPT element.... and was being referenced as a template.
I realize that an answer was already accepted for this, but from a "strictly *nix purist angle" it seems like the right tool for the job is pcregrep
, which doesn't seem to have been mentioned yet. Try changing the lines:
echo $f | grep -oEi '[0-9]+_([a-z]+)_[0-9a-z]*'
name=$?
to the following:
name=$(echo $f | pcregrep -o1 -Ei '[0-9]+_([a-z]+)_[0-9a-z]*')
to get only the contents of the capturing group 1.
The pcregrep
tool utilizes all of the same syntax you've already used with grep
, but implements the functionality that you need.
The parameter -o
works just like the grep
version if it is bare, but it also accepts a numeric parameter in pcregrep
, which indicates which capturing group you want to show.
With this solution there is a bare minimum of change required in the script. You simply replace one modular utility with another and tweak the parameters.
Interesting Note: You can use multiple -o arguments to return multiple capture groups in the order in which they appear on the line.
The .NET documentation says: State Property: A bitwise combination of the ConnectionState values
So I think you should check
!myConnection.State.HasFlag(ConnectionState.Open)
instead of
myConnection.State != ConnectionState.Open
because State can have multiple flags.
SQL keywords are case insensitive themselves.
Names of tables, columns etc, have a case sensitivity which is database dependent - you should probably assume that they are case sensitive unless you know otherwise (In many databases they aren't though; in MySQL table names are SOMETIMES case sensitive but most other names are not).
Comparing data using =, >, < etc, has a case awareness which is dependent on the collation settings which are in use on the individual database, table or even column in question. It's normal however, to keep collation fairly consistent within a database. We have a few columns which need to store case-sensitive values; they have a collation specifically set.
We like instance-store. It forces us to make our instances completely recyclable, and we can easily automate the process of building a server from scratch on a given AMI. This also means we can easily swap out AMIs. Also, EBS still has performance problems from time to time.
None is used to indicate "not set", whereas any other value is used to indicate a "default" value.
Hence, if your class copes with empty strings and you like it as a default value, use "". If your class needs to check if the variable was set at all, use None.
Notice that it doesn't matter if your variable is a string initially. You can change it to any other type/value at any other moment.

You require a plugin to format JSON. To install the plugin do the following steps:
I got the same error in my microservice project.The property itself missed in my yml file.So I added property name and value that resolves my problem
The preprocessor is looking for StdCUtil/split.h
in
./
(i.e. /root/Core/
, the directory that contains the #include statement). So ./
+ StdCUtil/split.h
= ./StdCUtil/split.h
and the file is missingand in
$INC_DIR
(i.e. ../StdCUtil/
= /root/Core/../StdCUtil/
= /root/StdCUtil/
). So ../StdCUtil/
+ StdCUtil/split.h
= ../StdCUtil/StdCUtil/split.h
and the file is missingYou can fix the error changing the $INC_DIR
variable (best solution):
$INC_DIR = ../
or the include directive:
#include "split.h"
but in this way you lost the "path syntax" that makes it very clear what namespace or module the header file belongs to.
Reference:
EDIT/UPDATE
It should also be
CXX = g++
CXXFLAGS = -c -Wall -I$(INC_DIR)
...
%.o: %.cpp $(DEPS)

A use case which might not apply anymore but for your nerd pleasure: On the Amiga, the CPU and the graphics/audio chips would fight for accessing a certain area of RAM (the first 2MB of RAM to be specific). So when you had only 2MB RAM (or less), displaying complex graphics plus playing sound would kill the performance of the CPU.
In assembler, you could interleave your code in such a clever way that the CPU would only try to access the RAM when the graphics/audio chips were busy internally (i.e. when the bus was free). So by reordering your instructions, clever use of the CPU cache, the bus timing, you could achieve some effects which were simply not possible using any higher level language because you had to time every command, even insert NOPs here and there to keep the various chips out of each others radar.
Which is another reason why the NOP (No Operation - do nothing) instruction of the CPU can actually make your whole application run faster.
[EDIT] Of course, the technique depends on a specific hardware setup. Which was the main reason why many Amiga games couldn't cope with faster CPUs: The timing of the instructions was off.
There's no difference, ==
is a synonym for =
(for the C/C++ people, I assume). See here, for example.
You could double-check just to be really sure or just for your interest by looking at the bash source code, should be somewhere in the parsing code there, but I couldn't find it straightaway.

When you need the column names, but do not want to grab entries:
PreparedStatement stmt = connection.prepareStatement("SHOW COLUMNS FROM `yourTable`");
ResultSet set = stmt.executeQuery();
//store all of the columns names
List<String> names = new ArrayList<>();
while (set.next()) { names.add(set.getString("Field")); }

Your results will not be helpful unless the arrays are first sorted. To sort an array, run it through Sort-Object.
$x = @(5,1,4,2,3)
$y = @(2,4,6,1,3,5)
Compare-Object -ReferenceObject ($x | Sort-Object) -DifferenceObject ($y | Sort-Object)
On a semi-related note, if you want to start a process that has more privileges than your current process (say, launching an admin app, which requires Administrator rights, from the main app running as a normal user), you can't do so using CreateProcess() on Vista since it won't trigger the UAC dialog (assuming it is enabled). The UAC dialog is triggered when using ShellExecute(), though.
The pedantic answer (though not necessarily the most useful one, depending on what you want to do with the result) is:
string.length() * 2
Java strings are physically stored in UTF-16BE
encoding, which uses 2 bytes per code unit, and String.length()
measures the length in UTF-16 code units, so this is equivalent to:
final byte[] utf16Bytes= string.getBytes("UTF-16BE");
System.out.println(utf16Bytes.length);
And this will tell you the size of the internal char
array, in bytes.
Note: "UTF-16"
will give a different result from "UTF-16BE"
as the former encoding will insert a BOM, adding 2 bytes to the length of the array.
Try adding multiple spaces (two spaces = one <br>
):
mycode(space)(space)(space)(space)
On CentOS 6.x and Redhat 6.x systems, the openjdk-devel package contains the jdk. It's sensible enough if you are familiar with the -devel pattern used in RedHat, but confusing if you're looking for a jdk package that conforms to java naming standards.
You can use attribute selectors but they won't work in IE6 like meder said, there are javascript workarounds to that tho. Check Selectivizr

Is it possible to have multiple version of tensorflow on the same OS?
Yes, you can use python virtual environments for this. From the docs:
A Virtual Environment is a tool to keep the dependencies required by different projects in separate places, by creating virtual Python environments for them. It solves the “Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keeps your global site-packages directory clean and manageable.
After you have install virtualenv (see the docs), you can create a virtual environment for the tutorial and install the tensorflow version you need in it:
PATH_TO_PYTHON=/usr/bin/python3.5
virtualenv -p $PATH_TO_PYTHON my_tutorial_env
source my_tutorial_env/bin/activate # this activates your new environment
pip install tensorflow==1.1
PATH_TO_PYTHON
should point to where python is installed on your system.
When you want to use the other version of tensorflow execute:
deactivate my_tutorial_env
Now you can work again with the tensorflow version that was already installed on your system.
The java application takes too long to respond(maybe due start-up/jvm being cold) thus you get the proxy error.
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /lin/Campaignn.jsp.
As Albert Maclang said amending the http timeout configuration may fix the issue. I suspect the java application throws a 500+ error thus the apache gateway error too. You should look in the logs.
You could use the library lxml (Note top level link is now spam) , which is a superset of ElementTree. Its tostring() method includes a parameter pretty_print - for example:
>>> print(etree.tostring(root, pretty_print=True))
<root>
<child1/>
<child2/>
<child3/>
</root>
There is an open source library [disclaimer: that I wrote]: LazyCache that IMO covers your requirement with two lines of code:
IAppCache cache = new CachingService();
var cachedResults = cache.GetOrAdd("CacheKey",
() => SomeHeavyAndExpensiveCalculation());
It has built in locking by default so the cacheable method will only execute once per cache miss, and it uses a lambda so you can do "get or add" in one go. It defaults to 20 minutes sliding expiration.
There's even a NuGet package ;)
An extension to Joachim Isaksson's answer: Quite often I need something from the middle of a long file, e.g. lines 5001 to 5020, in which case you can combine head
with tail
:
head -5020 file.txt | tail -20 | grep x
This gets the first 5020 lines, then shows only the last 20 of those, then pipes everything to grep.
(Edited: fencepost error in my example numbers, added pipe to grep)
How about:
String.prototype.strcmp = function(s) {
if (this < s) return -1;
if (this > s) return 1;
return 0;
}
Then, to compare s1 with 2:
s1.strcmp(s2)
After reading a bunch of people's comments online about this, my first reaction was that this is basically one of those really unimportant debates. However, my initial interest was to find out the right format so I could be consistent with my file naming practice.
Long story short, the creator of YAML are saying .yaml
, but personally I keep doing .yml
. That just makes more sense to me. So I went on the journey to find affirmation and soon enough, I realise that docker uses .yml
everywhere. I've been writing docker-compose.yml
files all this time, while you keep seeing in kubernetes' docs kubectl apply -f *.yaml
...
So, in conclusion, both formats are obviously accepted and if you are on the other end, (ie: writing systems that receive a YAML file as input) you should allow for both. That seems like another snake case versus camel case thingy...
I tried subtract, but the result was not consistent.
If I run df1.subtract(df2)
, not all lines of df1 are shown on the result dataframe, probably due distinct
cited on the docs.
This solved my problem:
df1.exceptAll(df2)
This is really old issue, but I just had similar problem. I was doing something like this :
// entity
$entityOne = $this->em->find(Parent::class, 1);
// do something on other entites (SomeEntityClass)
$this->em->persist($entity);
$this->em->flush();
$this->em->clear();
// and at end I was trying to save changes to first one by
$this->em->persist($entityOne);
$this->em->flush();
$this->em->clear();
Problem was that clear detach all entities including the first one and throw error The EntityManager is closed.
In my case solution was to just do clear on distinct type of Entity and leave $entityOne
still under EM:
$this->em->clear(SomeEntityClass::class);
File f = new File(fileName);
byte[] fileContent = msg.getByteSequenceContent();
Path path = Paths.get(f.getAbsolutePath());
try {
Files.write(path, fileContent);
} catch (IOException ex) {
Logger.getLogger(Agent2.class.getName()).log(Level.SEVERE, null, ex);
}
As documented in ?legend
you do this like so:
plot(1:10,type = "n")
abline(v=seq(1,10,1), col='grey', lty='dotted')
legend(1, 5, "This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",box.lwd = 0,box.col = "white",bg = "white")
points(1:10,1:10)
Line breaks are achieved with the new line character \n
. Making the points still visible is done simply by changing the order of plotting. Remember that plotting in R is like drawing on a piece of paper: each thing you plot will be placed on top of whatever's currently there.
Note that the legend text is cut off because I made the plot dimensions smaller (windows.options does not exist on all R platforms).
As of Jackson 1.6, you can use:
JsonNode node = mapper.valueToTree(map);
or
JsonNode node = mapper.convertValue(object, JsonNode.class);

This answer is an attempt at a technical answer rather than opinion.
If we want to be POSIX purists, we define a line as:
A sequence of zero or more non- <newline> characters plus a terminating <newline> character.
Source: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_206
An incomplete line as:
A sequence of one or more non- <newline> characters at the end of the file.
Source: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_195
A text file as:
A file that contains characters organized into zero or more lines. The lines do not contain NUL characters and none can exceed {LINE_MAX} bytes in length, including the <newline> character. Although POSIX.1-2008 does not distinguish between text files and binary files (see the ISO C standard), many utilities only produce predictable or meaningful output when operating on text files. The standard utilities that have such restrictions always specify "text files" in their STDIN or INPUT FILES sections.
Source: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_397
A string as:
A contiguous sequence of bytes terminated by and including the first null byte.
Source: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_396
From this then, we can derive that the only time we will potentially encounter any type of issues are if we deal with the concept of a line of a file or a file as a text file (being that a text file is an organization of zero or more lines, and a line we know must terminate with a <newline>).
Case in point: wc -l filename
.
From the wc
's manual we read:
A line is defined as a string of characters delimited by a <newline> character.
What are the implications to JavaScript, HTML, and CSS files then being that they are text files?
In browsers, modern IDEs, and other front-end applications there are no issues with skipping EOL at EOF. The applications will parse the files properly. It has to since not all Operating Systems conform to the POSIX standard, so it would be impractical for non-OS tools (e.g. browsers) to handle files according to the POSIX standard (or any OS-level standard).
As a result, we can be relatively confident that EOL at EOF will have virtually no negative impact at the application level - regardless if it is running on a UNIX OS.
At this point we can confidently say that skipping EOL at EOF is safe when dealing with JS, HTML, CSS on the client-side. Actually, we can state that minifying any one of these files, containing no <newline> is safe.
We can take this one step further and say that as far as NodeJS is concerned it too cannot adhere to the POSIX standard being that it can run in non-POSIX compliant environments.
What are we left with then? System level tooling.
This means the only issues that may arise are with tools that make an effort to adhere their functionality to the semantics of POSIX (e.g. definition of a line as shown in wc
).
Even so, not all shells will automatically adhere to POSIX. Bash for example does not default to POSIX behavior. There is a switch to enable it: POSIXLY_CORRECT
.
Food for thought on the value of EOL being <newline>: https://www.rfc-editor.org/old/EOLstory.txt
Staying on the tooling track, for all practical intents and purposes, let's consider this:
Let's work with a file that has no EOL. As of this writing the file in this example is a minified JavaScript with no EOL.
curl http://cdnjs.cloudflare.com/ajax/libs/AniJS/0.5.0/anijs-min.js -o x.js
curl http://cdnjs.cloudflare.com/ajax/libs/AniJS/0.5.0/anijs-min.js -o y.js
$ cat x.js y.js > z.js
-rw-r--r-- 1 milanadamovsky 7905 Aug 14 23:17 x.js
-rw-r--r-- 1 milanadamovsky 7905 Aug 14 23:17 y.js
-rw-r--r-- 1 milanadamovsky 15810 Aug 14 23:18 z.js
Notice the cat
file size is exactly the sum of its individual parts. If the concatenation of JavaScript files is a concern for JS files, the more appropriate concern would be to start each JavaScript file with a semi-colon.
As someone else mentioned in this thread: what if you want to cat
two files whose output becomes just one line instead of two? In other words, cat
does what it's supposed to do.
The man
of cat
only mentions reading input up to EOF, not <newline>. Note that the -n
switch of cat
will also print out a non- <newline> terminated line (or incomplete line) as a line - being that the count starts at 1 (according to the man
.)
-n Number the output lines, starting at 1.
Now that we understand how POSIX defines a line , this behavior becomes ambiguous, or really, non-compliant.
Understanding a given tool's purpose and compliance will help in determining how critical it is to end files with an EOL. In C, C++, Java (JARs), etc... some standards will dictate a newline for validity - no such standard exists for JS, HTML, CSS.
For example, instead of using wc -l filename
one could do awk '{x++}END{ print x}' filename
, and rest assured that the task's success is not jeopardized by a file we may want to process that we did not write (e.g. a third party library such as the minified JS we curl
d) - unless our intent was truly to count lines in the POSIX compliant sense.
Conclusion
There will be very few real life use cases where skipping EOL at EOF for certain text files such as JS, HTML, and CSS will have a negative impact - if at all. If we rely on <newline> being present, we are restricting the reliability of our tooling only to the files that we author and open ourselves up to potential errors introduced by third party files.
Moral of the story: Engineer tooling that does not have the weakness of relying on EOL at EOF.
Feel free to post use cases as they apply to JS, HTML and CSS where we can examine how skipping EOL has an adverse effect.

The same way you do it in other db system, you can use the name of the db for identifying double named tables. unique tablenames can used directly.
select * from ttt.table_name;
or if table name in all attached databases is unique
select * from my_unique_table_name;
But I think the of of sqlite-shell is only for manual lookup or manual data manipulation and therefor this way is more inconsequential
normally you would use sqlite-command-line in a script
Another simple way using JOIN
and INSTR
Sub Sample()
Dim Mainfram(4) As String, strg As String
Dim cel As Range
Dim Delim As String
Delim = "#"
Mainfram(0) = "apple"
Mainfram(1) = "pear"
Mainfram(2) = "orange"
Mainfram(3) = "fruit"
strg = Join(Mainfram, Delim)
strg = Delim & strg
For Each cel In Selection
If InStr(1, strg, Delim & cel.Value & Delim, vbTextCompare) Then _
Rows(cel.Row).Style = "Accent1"
Next cel
End Sub

Some explanations. Your original query will be executed as :
SELECT
CASE 0
WHEN 0=0 THEN 1 -- condition evaluates to 1, then 0 (from CASE 0)compares to 1 - false
WHEN 0<1 THEN 2 -- condition evaluates to 1,then 0 (from CASE 0)compares to 1 - false
WHEN 0>100 and 0<201 THEN 3 -- evaluates to 0 ,then 0 (from CASE 0)compares to 0 - true
ELSE 6, ...
it's why you always get 3

This is available for Git v.1.8.0 or newer. (Sources: 1.7.9 ref, 1.8.0 ref)
This code counts rows with date range:
Controller:
$this->load->model("YourModelName");
$data ['query'] = $this->YourModelName->get_report();
Model:
public function get_report()
{
$query = $this->db->query("SELECT *
FROM reservation WHERE arvdate <= '2016-7-20' AND dptrdate >= '2016-10-25' ");
return $query;
}
where 'arvdate' and 'dptrdate' are two dates on database and 'reservation' is the table name.
View:
<?php
echo $query->num_rows();
?>
This code is to return number of rows. To return table data, then use
$query->rows();
return $row->table_column_name;

Let me make a few statement that can put the difference in focus:
We migrated our code base from Ant to Maven
All 3rd party librairies have been uploaded to Nexus. Maven is using Nexus as a source for libraries.
Basic functionalities of a repository manager like Sonatype are:
have you tried line-height:1em;? I recall that that's the way to get it to center vertically.
Target= "_blank"
This does it in html, give it a try in C#
Use 3 curly braces if you want to echo
{{{ $usersType or '' }}}
The icon will adopt the color from value of the color
css property of it's parent.
You can either add this directly to the style:
<span class="glyphicon glyphicon-user" style="color:blue"></span>
Or you can add it as a class to your icon and then set the font color to it in CSS
HTML
<span class="glyphicon glyphicon-search"></span>
<span class="glyphicon glyphicon-user blue"></span>
<span class="glyphicon glyphicon-trash"></span>
CSS
.blue {
color: blue;
}

The only important question is "How is the code simpler, better readable, easier to understand?" If it is simpler with multiple returns, then use them.
chmod a+x
modifies the argument's mode while chmod 755
sets it. Try both variants on something that has full or no permissions and you will notice the difference.
why not simply just give the input field where you want to jump to a id and do a simple focus
$("#newListField").focus();
I dont think you need regex to achieve this. I would look at the SubString method along with the indexOf method. If you need more help, add a comment showing what you have attempted and I will offer more help.
Instead of using lxml use html.parser, you can use this piece of code:

In oracle, generally speaking, there are number of facts that I will mention in following section:
Therefore, your question, "to see all tablespaces and datafiles belong to SCOTT" is s bit wrong.
However, there are some DBA views encompass information about all database objects, regardless of the owner. Only users with DBA privileges can access these views: DBA_DATA_FILES, DBA_TABLESPACES, DBA_FREE_SPACE, DBA_SEGMENTS.
So, connect to your DB as sysdba and run query through these helpful views. For example this query can help you to find all tablespaces and their data files that objects of your user are located:
SELECT DISTINCT sgm.TABLESPACE_NAME , dtf.FILE_NAME
FROM DBA_SEGMENTS sgm
JOIN DBA_DATA_FILES dtf ON (sgm.TABLESPACE_NAME = dtf.TABLESPACE_NAME)
WHERE sgm.OWNER = 'SCOTT'
To stream the file to the browser, see Stack Overflow question How to stream a PDF file as binary to the browser using .NET 2.0 - note that, with minor variations, this should work whether you're serving up a file from the file system or dynamically generated.
With that said, the referenced MSDN article takes a rather simplistic view of the world, so you may want to read Successfully Stream a PDF to browser through HTTPS as well for some of the headers you may need to supply.
Using that approach, an iframe is probably the best way to go. Have one webform that streams the file, and then put the iframe on another page with its src
attribute set to the first form.
nanosleep
is a better choice than usleep
- it is more resilient against interrupts.
As others have said, you can't have an implicit conversion, and that's by-design.
If you want you can avoid the need to specify the underlying type in the cast.
template <typename E>
constexpr typename std::underlying_type<E>::type to_underlying(E e) noexcept {
return static_cast<typename std::underlying_type<E>::type>(e);
}
std::cout << foo(to_underlying(b::B2)) << std::endl;
To handle this problem in a clean way, I suggest to use brew
and jenv
.
JAVA_VERSION=11
brew reinstall jenv
brew reinstall openjdk@${JAVA_VERSION}
jenv add /usr/local/opt/openjdk@${JAVA_VERSION}/
jenv global ${JAVA_VERSION}
~/.bashrc
or ~/.zshrc
export PATH="$HOME/.jenv/bin:$PATH"
eval "$(jenv init -)"
export JAVA_HOME="$HOME/.jenv/versions/`jenv version-name`"
Then restart your shell and try to execute java -version
Note: If you have this problem, your current JDK version is not existent or misconfigured (or may be you have only JRE).
In the other hand, there is some packages in AngularJS which are helpful (in AJAX WEB):

just do this
try

//some code
try
{
int idNumber = function2();
}
finally
{
do stuff here....
}
}
catch(Exception e)
{//... perhaps something here}
For all intents and purposes the finally block will always execute. Now there are a couple of exceptions where it won't actually execute: task killing the program, and there is a fast fail security exception which kills the application instantly. Other than that, an exception will be thrown in function 2, the finally block will execute the needed code and then catch the exception in the outer catch block.
You have to set the numberOfLines
property on the UILabel
. The default is 1, if you set it to 0 it will remove all limits.
I don't know if this will help, but here's the SWT FAQ question How do I use Mozilla as the Browser's underlying renderer?
Edit: Having researched this further, it sounds like this isn't possible in Eclipse 3.4, but may be slated for a later release.
I'm using a ajax post to run a delete method (happens to be from a visjs timeline but that's not relelvant). This is what I sis:
This is my Index.cshtml
@Scripts.Render("~/bundles/schedule")
@Styles.Render("~/bundles/visjs")
@Html.AntiForgeryToken()
<!-- div to attach schedule to -->
<div id='schedule'></div>
<!-- div to attach popups to -->
<div id='dialog-popup'></div>
All I added here was @Html.AntiForgeryToken()
to make the token appear in the page
Then in my ajax post I used:
$.ajax(
{
type: 'POST',
url: '/ScheduleWorks/Delete/' + item.id,
data: {
'__RequestVerificationToken':
$("input[name='__RequestVerificationToken']").val()
}
}
);
Which adds the token value, scraped off the page, to the fields posted
Before this I tried putting the value in the headers but I got the same error
Feel free to post improvements. This certainly seems to be a simple approach that I can understand
Both git merge --squash
and git rebase --interactive
can produce a "squashed" commit.
But they serve different purposes.
will produce a squashed commit on the destination branch, without marking any merge relationship.
(Note: it does not produce a commit right away: you need an additional git commit -m "squash branch"
)
This is useful if you want to throw away the source branch completely, going from (schema taken from SO question):
git checkout stable
X stable
/
a---b---c---d---e---f---g tmp
to:
git merge --squash tmp
git commit -m "squash tmp"
X-------------------G stable
/
a---b---c---d---e---f---g tmp
and then deleting tmp
branch.
Note: git merge
has a --commit
option, but it cannot be used with --squash
. It was never possible to use --commit
and --squash
together.
Since Git 2.22.1 (Q3 2019), this incompatibility is made explicit:
See commit 1d14d0c (24 May 2019) by Vishal Verma (reloadbrain
).
(Merged by Junio C Hamano -- gitster
-- in commit 33f2790, 25 Jul 2019)
merge
: refuse--commit
with--squash
Previously, when
--squash
was supplied, 'option_commit
' was silently dropped. This could have been surprising to a user who tried to override the no-commit behavior of squash using--commit
explicitly.
git/git
builtin/merge.c#cmd_merge()
now includes:
if (option_commit > 0)
die(_("You cannot combine --squash with --commit."));
replays some or all of your commits on a new base, allowing you to squash (or more recently "fix up", see this SO question), going directly to:
git checkout tmp
git rebase -i stable
stable
X-------------------G tmp
/
a---b
If you choose to squash all commits of tmp
(but, contrary to merge --squash
, you can choose to replay some, and squashing others).
So the differences are:
squash
does not touch your source branch (tmp
here) and creates a single commit where you want.rebase
allows you to go on on the same source branch (still tmp
) with:
It´s out of the scope of the question, but I think it might be also interesting to know how to link to a route. The query would look like this:
https://www.google.es/maps/dir/'52.51758801683297,13.397978515625027'/'52.49083837044266,13.369826049804715'
Though this is an old question and asked several times, here's what I'm doing after hours fidgeting with here
strings, and the only option that worked for me is to store the value in a file during while loop sub-shells and then retrieve it. Simple.
Use echo
statement to store and cat
statement to retrieve. And the bash user must chown
the directory or have read-write chmod
access.
#write to file
echo "1" > foo.txt
while condition; do
if (condition); then
#write again to file
echo "2" > foo.txt
fi
done
#read from file
echo "Value of \$foo in while loop body: $(cat foo.txt)"
I wrote a quick simple app recent that handle the management of various version of node and npm. It allows you to choose different version of node and npm to download and select which version to use. Check it out and see if it's something that's useful.
This is because findViewById()
searches in the activity_main
layout, while the button is located in the fragment's layout fragment_main
.
Move that piece of code in the onCreateView()
method of the fragment:
//...
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
Button buttonClick = (Button)rootView.findViewById(R.id.button);
buttonClick.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
onButtonClick((Button) view);
}
});
Notice that now you access it through rootView
view:
Button buttonClick = (Button)rootView.findViewById(R.id.button);
otherwise you would get again NullPointerException.
after spending a few hours searching for a solution, I decided to create my own. He it is:
function CustomInitSelect2(element, options) {
if (options.url) {
$.ajax({
type: 'GET',
url: options.url,
dataType: 'json'
}).then(function (data) {
element.select2({
data: data
});
if (options.initialValue) {
element.val(options.initialValue).trigger('change');
}
});
}
}
And you can initialize the selects using this function:
$('.select2').each(function (index, element) {
var item = $(element);
if (item.data('url')) {
CustomInitSelect2(item, {
url: item.data('url'),
initialValue: item.data('value')
});
}
else {
item.select2();
}
});
And of course, here is the html:
<select class="form-control select2" id="test1" data-url="mysite/load" data-value="123"></select>
Use HH
for 24 hour hours format:
DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")
Or the tt
format specifier for the AM/PM
part:
DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss tt")
Take a look at the custom Date and Time format strings documentation.
So, rather return the whole object
first, just wrap it to json_encode
and then return it. This will return a proper and valid object.
public function id($id){
$promotion = Promotion::find($id);
return json_encode($promotion);
}
Or, For DB this will be just like,
public function id($id){
$promotion = DB::table('promotions')->first();
return json_encode($promotion);
}
I think it may help someone else.
I've got this exact error, but in my case I was binding values for the LIMIT
clause without specifying the type. I'm just dropping this here in case somebody gets this error for the same reason. Without specifying the type LIMIT :limit OFFSET :offset;
resulted in LIMIT '10' OFFSET '1';
instead of LIMIT 10 OFFSET 1;
. What helps to correct that is the following:
$stmt->bindParam(':limit', intval($limit, 10), \PDO::PARAM_INT);
$stmt->bindParam(':offset', intval($offset, 10), \PDO::PARAM_INT);
You were on the right track with response.getOutputStream()
, but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:
@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
// convert JSON to Employee
Employee emp = convertSomehow(json);
// generate the file
PdfUtil.showHelp(emp);
// retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
byte[] contents = (...);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_PDF);
// Here you have to set the actual filename of your pdf
String filename = "output.pdf";
headers.setContentDispositionFormData(filename, filename);
headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
return response;
}
Notes:
showHelp
is not a good ideabyte[]
: example hereshowHelp()
to avoid overwriting the file if two users send a request at the same timeNo new line:
File.AppendAllText("file.txt", DateTime.Now.ToString());
and then to get a new line after OK:
File.AppendAllText("file.txt", string.Format("{0}{1}", "OK", Environment.NewLine));
For people who have the same issue of querySelector
or getElementById
that returns the following error:
Uncaught TypeError: Cannot read property 'appendChild' of null
but you have a class name or id in the HTML...
If your script tag is in the head, the JavaScript is loaded before your HTML. You will need to add defer

Create a fake update to enforce the rowlock.
UPDATE <tablename> (ROWLOCK) SET <somecolumn> = <somecolumn> WHERE id=1
If that's not locking your row, god knows what will.
After this "UPDATE
" you can do your SELECT (ROWLOCK)
and subsequent updates.

Its all about Method Overloading.
There are individual methods for each data type in println() method
If you pass object :
Prints an Object and then terminate the line. This method calls at first String.valueOf(x) to get the printed object's string value, then behaves as though it invokes print(String) and then println().
If you pass Primitive type:
corresponding primitive type method calls
if you pass String :
corresponding println(String x) method calls
So, finally I realized what the problem is. It is not a Jackson configuration issue as I doubted.
Actually the problem was in ApplesDO Class:
public class ApplesDO {
private String apple;
public String getApple() {
return apple;
}
public void setApple(String apple) {
this.apple = apple;
}
public ApplesDO(CustomType custom) {
//constructor Code
}
}
There was a custom constructor defined for the class making it the default constructor. Introducing a dummy constructor has made the error to go away:
public class ApplesDO {
private String apple;
public String getApple() {
return apple;
}
public void setApple(String apple) {
this.apple = apple;
}
public ApplesDO(CustomType custom) {
//constructor Code
}
//Introducing the dummy constructor
public ApplesDO() {
}
}

Update 2015-07-18: Fixed mistake in private Encrypt() method by comments of @bpsilver and @Evereq. IV was accidentally encrypted, is now prepended in clear text as expected by Decrypt().

In the context of data storage, serialization (or serialisation) is the process of translating data structures or object state into a format that can be stored (for example, in a file or memory buffer) or transmitted (for example, across a network connection link) and reconstructed later. [...]
The opposite operation, extracting a data structure from a series of bytes, is deserialization. From Wikipedia
In Python "serialization" does nothing else than just converting the given data structure (e.g. a dict
) into its valid JSON pendant (object).
True
will be converted to JSONs true
and the dictionary itself will then be encapsulated in quotes.True
/ False
, true
/ false
json
is the standard way to do serialization:Code example:
data = {
"president": {
"name": "Zaphod Beeblebrox",
"species": "Betelgeusian",
"male": True,
}
}
import json
json_data = json.dumps(data, indent=2) # serialize
restored_data = json.loads(json_data) # deserialize
# serialized json_data now looks like:
# {
# "president": {
# "name": "Zaphod Beeblebrox",
# "species": "Betelgeusian",
# "male": true
# }
# }

Take a look at ?legend
and try this:
legend('topright', names(a)[-1] ,
lty=1, col=c('red', 'blue', 'green',' brown'), bty='n', cex=.75)
The original checked
attribute (HTML 4 and before) did not require a value on it - if it existed, the element was "checked", if not, it wasn't.
This, however is not valid for XHTML that followed HTML 4.
The standard proposed to use checked="checked"
as a condition for true - so both ways you posted end up doing the same thing.
It really doesn't matter which one you use - use the one that makes most sense to you and stick to it (or agree with your team which way to go).
I found another solution to put the style in the main html like this
<style id="iframestyle">
html {
color: white;
background: black;
}
</style>
<style>
html {
color: initial;
background: initial;
}
iframe {
border: none;
}
</style>
and then in iframe do this (see the js onload)
<iframe onload="iframe.document.head.appendChild(ifstyle)" name="log" src="/upgrading.log"></iframe>
and in js
<script>
ifstyle = document.getElementById('iframestyle')
iframe = top.frames["log"];
</script>
It may not be the best solution, and it certainly can be improved, but it is another option if you want to keep a "style" tag in parent window
I think Amith Koujalgi is correct but also, in cases where the webservice responses are in JSON then it might be more useful to see the results in a clean JSON format instead of a very long string. Just add | grep }| python -mjson.tool to the end of curl commands here is two examples:
GET approach with JSON result
curl -i -H "Accept: application/json" http://someHostName/someEndpoint | grep }| python -mjson.tool
POST approach with JSON result
curl -X POST -H "Accept: Application/json" -H "Content-Type: application/json" http://someHostName/someEndpoint -d '{"id":"IDVALUE","name":"Mike"}' | grep }| python -mjson.tool
select name, games, goals
from tblMadrid where name = 'ronaldo'
union
select name, games, goals
from tblBarcelona where name = 'messi'
ORDER BY goals
The following works great for me and seems to be a lot simpler than the examples that have already been given.
$dob_date = "01";
$dob_month = "01";
$dob_year = "1970";
$year = gmdate("Y");
$month = gmdate("m");
$day = gmdate("d");
$age = $year-$dob_year; // $age calculates the user's age determined by only the year
if($month < $dob_month) { // this checks if the current month is before the user's month of birth
$age = $age-1;
} else if($month == $dob_month && $day >= $dob_date) { // this checks if the current month is the same as the user's month of birth and then checks if it is the user's birthday or if it is after it
$age = $age;
} else if($month == $dob_month && $day < $dob_date) { //this checks if the current month is the user's month of birth and checks if it before the user's birthday
$age = $age-1;
} else {
$age = $age;
}
I've tested and actively use this code, it might seem a little cumbersome but it is very simple to use and edit and is quite accurate.

I realize this is an old post, but it ranks high in Google, so I'm adding what I figured out for MY problem. If you have a mix of table types (e.g. MyISAM and InnoDB), you will get this error as well. In this case, InnoDB is the default table type, but one table needed fulltext searching so it was migrated to MyISAM. In this situation, you cannot create a foreign key in the InnoDB table that references the MyISAM table.

Go with the following if you really want to use a loop. Nobody has actually answered how to feed data in a loop:
def plot(data):

x, y = data[k].keys(), data[k].values
plt.subplot(63, 10, idx)
plt.bar(x, y)

I had the same problem and apparently is solved now, despite this and some other gdi+ exceptions are very misleading, I found that actually the problem was that the parameter being sent to a Bitmap constructor was not valid. I have this code:
using (System.IO.FileStream fs = new System.IO.FileStream(inputImage, System.IO.FileMode.Open, System.IO.FileAccess.ReadWrite))
{
try
{
using (Bitmap bitmap = (Bitmap)Image.FromStream(fs, true, false))
{
try
{
bitmap.Save(OutputImage + ".bmp", System.Drawing.Imaging.ImageFormat.Bmp);
GC.Collect();
}
catch (Exception ex)
{
throw ex;
}
}
}
catch (ArgumentException aex)
{
throw new Exception("The file received from the Map Server is not a valid jpeg image", aex);
}
}
The following line was causing an error:
Bitmap bitmap = (Bitmap)Image.FromStream(fs, true, false)
The file stream was built from the file downloaded from the Map Server. My app was sending the request incorrectly to get the image, and the server was returning something with the jpg extension, but was actually a html telling me that an error ocurred. So I was taking that image and trying to build a Bitmap with it. The fix was to control/ validate the image for a valid jpeg image.
Hope it helps!
PDOStatement::fetch returns a row from the result set. The parameter PDO::FETCH_ASSOC
tells PDO to return the result as an associative array.
The array keys will match your column names. If your table contains columns 'email' and 'password', the array will be structured like:
Array
(
[email] => '[email protected]'
[password] => 'yourpassword'
)
To read data from the 'email' column, do:
$user['email'];
and for 'password':
$user['password'];
It's not possible to create a many-to-many relationship with a customized join table. In a many-to-many relationship EF manages the join table internally and hidden. It's a table without an Entity class in your model. To work with such a join table with additional properties you will have to create actually two one-to-many relationships. It could look like this:
public class Member
{
public int MemberID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public virtual ICollection<MemberComment> MemberComments { get; set; }
}
public class Comment
{
public int CommentID { get; set; }
public string Message { get; set; }
public virtual ICollection<MemberComment> MemberComments { get; set; }
}
public class MemberComment
{
[Key, Column(Order = 0)]
public int MemberID { get; set; }
[Key, Column(Order = 1)]
public int CommentID { get; set; }
public virtual Member Member { get; set; }
public virtual Comment Comment { get; set; }
public int Something { get; set; }
public string SomethingElse { get; set; }
}
If you now want to find all comments of members with LastName
= "Smith" for example you can write a query like this:
var commentsOfMembers = context.Members
.Where(m => m.LastName == "Smith")
.SelectMany(m => m.MemberComments.Select(mc => mc.Comment))
.ToList();
... or ...
var commentsOfMembers = context.MemberComments
.Where(mc => mc.Member.LastName == "Smith")
.Select(mc => mc.Comment)
.ToList();
Or to create a list of members with name "Smith" (we assume there is more than one) along with their comments you can use a projection:
var membersWithComments = context.Members
.Where(m => m.LastName == "Smith")
.Select(m => new
{
Member = m,
Comments = m.MemberComments.Select(mc => mc.Comment)
})
.ToList();
If you want to find all comments of a member with MemberId
= 1:
var commentsOfMember = context.MemberComments
.Where(mc => mc.MemberId == 1)
.Select(mc => mc.Comment)
.ToList();
Now you can also filter by the properties in your join table (which would not be possible in a many-to-many relationship), for example: Filter all comments of member 1 which have a 99 in property Something
:
var filteredCommentsOfMember = context.MemberComments
.Where(mc => mc.MemberId == 1 && mc.Something == 99)
.Select(mc => mc.Comment)
.ToList();
Because of lazy loading things might become easier. If you have a loaded Member
you should be able to get the comments without an explicit query:
var commentsOfMember = member.MemberComments.Select(mc => mc.Comment);
I guess that lazy loading will fetch the comments automatically behind the scenes.
Edit
Just for fun a few examples more how to add entities and relationships and how to delete them in this model:
1) Create one member and two comments of this member:
var member1 = new Member { FirstName = "Pete" };
var comment1 = new Comment { Message = "Good morning!" };
var comment2 = new Comment { Message = "Good evening!" };
var memberComment1 = new MemberComment { Member = member1, Comment = comment1,
Something = 101 };
var memberComment2 = new MemberComment { Member = member1, Comment = comment2,
Something = 102 };
context.MemberComments.Add(memberComment1); // will also add member1 and comment1
context.MemberComments.Add(memberComment2); // will also add comment2
context.SaveChanges();
2) Add a third comment of member1:
var member1 = context.Members.Where(m => m.FirstName == "Pete")
.SingleOrDefault();
if (member1 != null)
{
var comment3 = new Comment { Message = "Good night!" };
var memberComment3 = new MemberComment { Member = member1,
Comment = comment3,
Something = 103 };
context.MemberComments.Add(memberComment3); // will also add comment3
context.SaveChanges();
}
3) Create new member and relate it to the existing comment2:
var comment2 = context.Comments.Where(c => c.Message == "Good evening!")
.SingleOrDefault();
if (comment2 != null)
{
var member2 = new Member { FirstName = "Paul" };
var memberComment4 = new MemberComment { Member = member2,
Comment = comment2,
Something = 201 };
context.MemberComments.Add(memberComment4);
context.SaveChanges();
}
4) Create relationship between existing member2 and comment3:
var member2 = context.Members.Where(m => m.FirstName == "Paul")
.SingleOrDefault();
var comment3 = context.Comments.Where(c => c.Message == "Good night!")
.SingleOrDefault();
if (member2 != null && comment3 != null)
{
var memberComment5 = new MemberComment { Member = member2,
Comment = comment3,
Something = 202 };
context.MemberComments.Add(memberComment5);
context.SaveChanges();
}
5) Delete this relationship again:
var memberComment5 = context.MemberComments
.Where(mc => mc.Member.FirstName == "Paul"
&& mc.Comment.Message == "Good night!")
.SingleOrDefault();
if (memberComment5 != null)
{
context.MemberComments.Remove(memberComment5);
context.SaveChanges();
}
6) Delete member1 and all its relationships to the comments:
var member1 = context.Members.Where(m => m.FirstName == "Pete")
.SingleOrDefault();
if (member1 != null)
{
context.Members.Remove(member1);
context.SaveChanges();
}
This deletes the relationships in MemberComments
too because the one-to-many relationships between Member
and MemberComments
and between Comment
and MemberComments
are setup with cascading delete by convention. And this is the case because MemberId
and CommentId
in MemberComment
are detected as foreign key properties for the Member
and Comment
navigation properties and since the FK properties are of type non-nullable int
the relationship is required which finally causes the cascading-delete-setup. Makes sense in this model, I think.
If you've just killed a big query, it will take time to rollback
. If you issue another query before the killed query is done rolling back, you might get a lock timeout error. That's what happened to me. The solution was just to wait a bit.
Details:
I had issued a DELETE query to remove about 900,000 out of about 1 million rows.
I ran this by mistake (removes only 10% of the rows):
DELETE FROM table WHERE MOD(id,10) = 0
Instead of this (removes 90% of the rows):
DELETE FROM table WHERE MOD(id,10) != 0
I wanted to remove 90% of the rows, not 10%. So I killed the process in the MySQL command line, knowing that it would roll back all the rows it had deleted so far.
Then I ran the correct command immediately, and got a lock timeout exceeded
error soon after. I realized that the lock might actually be the rollback
of the killed query still happening in the background. So I waited a few seconds and re-ran the query.
in my case i was using compile sdk 23
and build tools 25.0.0
just changed compile sdk
to 25 and done..
Another category method you could use:
- (NSArray *) filteredArrayUsingBlock:(BOOL (^)(id obj))block {
NSIndexSet *const filteredIndexes = [self indexesOfObjectsPassingTest:^BOOL (id _Nonnull obj, NSUInteger idx, BOOL *_Nonnull stop) {
return block(obj);
}];
return [self objectsAtIndexes:filteredIndexes];
}
If you really want it to be FAST on Windows, you can do it using unsafe code with CopyMemory. CopyMemory is about 5x faster (e.g. 800MB of data takes 3s to copy via marshalling, while only taking .6s to copy via CopyMemory). This method does limit you to using only data which is actually stored in the struct blob itself, e.g. numbers, or fixed length byte arrays.
[DllImport("kernel32.dll", EntryPoint = "CopyMemory", SetLastError = false)]
private static unsafe extern void CopyMemory(void *dest, void *src, int count);
private static unsafe byte[] Serialize(TestStruct[] index)
{
var buffer = new byte[Marshal.SizeOf(typeof(TestStruct)) * index.Length];
fixed (void* d = &buffer[0])
{
fixed (void* s = &index[0])
{
CopyMemory(d, s, buffer.Length);
}
}
return buffer;
}
this configuration in app.js worked fine for me :
//production mode
if (process.env.NODE_ENV === "production") {
app.use(express.static(path.join(__dirname, "client/build")));
app.get("*", (req, res) => {
res.sendFile(path.join((__dirname + "/client/build/index.html")));
});
}
//build mode
app.get("*", (req, res) => {
res.sendFile(path.join(__dirname + "/client/public/index.html"));
});
If you want all the bars to get the same color (fill
), you can easily add it inside geom_bar
.
ggplot(data=df, aes(x=c1+c2/2, y=c3)) +
geom_bar(stat="identity", width=c2, fill = "#FF6666")
Add fill = the_name_of_your_var
inside aes
to change the colors depending of the variable :
c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) +
geom_bar(stat="identity", width=c2)
Use scale_fill_manual()
if you want to manually the change of colors.
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) +
geom_bar(stat="identity", width=c2) +
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))
Apply these two things.
You need to set the character set of your database to be utf8
.
You need to call the mysql_set_charset('utf8')
in the file where you made the connection with the database and right after the selection of database like mysql_select_db
use the mysql_set_charset
. That will allow you to add and retrieve data properly in whatever the language.

This is because your servlet is trying to access a request object which is no more exist.. A servlet's forward or include statement does not stop execution of method block. It continues to the end of method block or first return statement just like any other java method.
The best way to resolve this problem just set the page (where you suppose to forward the request) dynamically according your logic. That is:
protected void doPost(request , response){
String returnPage="default.jsp";
if(condition1){
returnPage="page1.jsp";
}
if(condition2){
returnPage="page2.jsp";
}
request.getRequestDispatcher(returnPage).forward(request,response); //at last line
}
and do the forward only once at last line...
you can also fix this problem using return statement after each forward() or put each forward() in if...else block
Code :
MediaQuery.of(context).size.width //to get the width of screen
MediaQuery.of(context).size.height //to get height of screen
You can use this to get a name of any provided member:
public static class MemberInfoGetting
{
public static string GetMemberName<T>(Expression<Func<T>> memberExpression)
{
MemberExpression expressionBody = (MemberExpression)memberExpression.Body;
return expressionBody.Member.Name;
}
}
To get name of a variable:
string testVariable = "value";
string nameOfTestVariable = MemberInfoGetting.GetMemberName(() => testVariable);
To get name of a parameter:
public class TestClass
{
public void TestMethod(string param1, string param2)
{
string nameOfParam1 = MemberInfoGetting.GetMemberName(() => param1);
}
}
You can use the nameof operator for parameters, variables and properties alike:
string testVariable = "value";
string nameOfTestVariable = nameof(testVariable);
Simply invoke orderBy()
as many times as you need it. For instance:
User::orderBy('name', 'DESC')
->orderBy('email', 'ASC')
->get();
Produces the following query:
SELECT * FROM `users` ORDER BY `name` DESC, `email` ASC
You either have to make the method Shared
or use an instance of the class General
:
Dim gen = New General()
gen.updateDynamics(get_prospect.dynamicsID)
or
General.updateDynamics(get_prospect.dynamicsID)
Public Shared Sub updateDynamics(dynID As Int32)
' ... '
End Sub
Building on @Prasath's answer. This is how you do it in Swift:
if application.respondsToSelector("isRegisteredForRemoteNotifications")
{
// iOS 8 Notifications
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: (.Badge | .Sound | .Alert), categories: nil));
application.registerForRemoteNotifications()
}
else
{
// iOS < 8 Notifications
application.registerForRemoteNotificationTypes(.Badge | .Sound | .Alert)
}
You can use the SO_RCVTIMEO and SO_SNDTIMEO socket options to set timeouts for any socket operations, like so:
struct timeval timeout;
timeout.tv_sec = 10;
timeout.tv_usec = 0;
if (setsockopt (sockfd, SOL_SOCKET, SO_RCVTIMEO, (char *)&timeout,
sizeof(timeout)) < 0)
error("setsockopt failed\n");
if (setsockopt (sockfd, SOL_SOCKET, SO_SNDTIMEO, (char *)&timeout,
sizeof(timeout)) < 0)
error("setsockopt failed\n");
Edit: from the setsockopt
man page:
SO_SNDTIMEO
is an option to set a timeout value for output operations. It accepts a struct timeval parameter with the number of seconds and microseconds used to limit waits for output operations to complete. If a send operation has blocked for this much time, it returns with a partial count or with the error EWOULDBLOCK if no data were sent. In the current implementation, this timer is restarted each time additional data are delivered to the protocol, implying that the limit applies to output portions ranging in size from the low-water mark to the high-water mark for output.
SO_RCVTIMEO
is an option to set a timeout value for input operations. It accepts a struct timeval parameter with the number of seconds and microseconds used to limit waits for input operations to complete. In the current implementation, this timer is restarted each time additional data are received by the protocol, and thus the limit is in effect an inactivity timer. If a receive operation has been blocked for this much time without receiving additional data, it returns with a short count or with the error EWOULDBLOCK if no data were received. The struct timeval parameter must represent a positive time interval; otherwise, setsockopt() returns with the error EDOM.
I recommend to use SMO (Enable TCP/IP Network Protocol for SQL Server). However, it was not available in my case.
I rewrote the WMI commands from Krzysztof Kozielczyk to PowerShell.
# Enable TCP/IP
Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocol -Filter "InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'" |
Invoke-CimMethod -Name SetEnable
# Open the right ports in the firewall
New-NetFirewallRule -DisplayName 'MSSQL$SQLEXPRESS' -Direction Inbound -Action Allow -Protocol TCP -LocalPort 1433
# Modify TCP/IP properties to enable an IP address
$properties = Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocolProperty -Filter "InstanceName='SQLEXPRESS' and ProtocolName = 'Tcp' and IPAddressName='IPAll'"
$properties | ? { $_.PropertyName -eq 'TcpPort' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '1433' }
$properties | ? { $_.PropertyName -eq 'TcpPortDynamic' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '' }
# Restart SQL Server
Restart-Service 'MSSQL$SQLEXPRESS'
Use Application.GetSaveAsFilename()
in the same way that you used Application.GetOpenFilename()
Parts of the GCC runtime (the exception handling, in particular) are dependent on the threading model being used. So, if you're using the version of the runtime that was built with POSIX threads, but decide to create threads in your own code with the Win32 APIs, you're likely to have problems at some point.
Even if you're using the Win32 threading version of the runtime you probably shouldn't be calling the Win32 APIs directly. Quoting from the MinGW FAQ:
As MinGW uses the standard Microsoft C runtime library which comes with Windows, you should be careful and use the correct function to generate a new thread. In particular, the
CreateThread
function will not setup the stack correctly for the C runtime library. You should use_beginthreadex
instead, which is (almost) completely compatible withCreateThread
.
You mixed the keys and the values.
Hashmap <Integer,String> hashmap = new HashMap<Integer, String>();
hashmap.put(100, "one");
hashmap.put(200, "two");
Afterwards a
hashmap.get(100);
will give you "one"
This what worked for me. set HeaderStyle-Width="5%", in the footer set textbox width Width="15",also set the width of your gridview to 100%. following is the one of the column of my gridview.

Anaconda or Miniconda?
Choose Anaconda if you:
Are new to conda or Python.
Like the convenience of having Python and over 1,500 scientific packages automatically installed at once.
Have the time and disk space---a few minutes and 3 GB.
Do not want to individually install each of the packages you want to use.
Choose Miniconda if you:
Do not mind installing each of the packages you want to use individually.
Do not have time or disk space to install over 1,500 packages at once.
Want fast access to Python and the conda commands and you wish to sort out the other programs later.
Simply use this view into stored procedure with required parameter/s (eg. in SQL Server) and parameter values in querying view.
Create stored procedure with View/ table: _spCallViewWithParameters
Execute procedure:
Just my 2 cents. This code combines two matrices or data.frames into one. If one data structure have lower number of rows then missing rows will be added with NA values.
combine.df <- function(x, y) {
rows.x <- nrow(x)
rows.y <- nrow(y)
if (rows.x > rows.y) {
diff <- rows.x - rows.y
df.na <- matrix(NA, diff, ncol(y))
colnames(df.na) <- colnames(y)
cbind(x, rbind(y, df.na))
} else {
diff <- rows.y - rows.x
df.na <- matrix(NA, diff, ncol(x))
colnames(df.na) <- colnames(x)
cbind(rbind(x, df.na), y)
}
}
df1 <- data.frame(1:10, row.names = 1:10)
df2 <- data.frame(1:5, row.names = 10:14)
combine.df(df1, df2)
Use lt pseudo selector:
$("a:lt(n)")
This matches the elements before the nth one (the nth element excluded). Numbering starts from 0.
OK, i just fixed this error.
This happens when there is an error in query or table doesn't exist.
Try debugging the query buy running it directly on phpmyadmin to confirm the validity of the mysql Query
You'll need to open the workbook to refer to it.
Sub Setwbk()
Dim wbk As Workbook
Set wbk = Workbooks.Open("F:\Quarterly Reports\2012 Reports\New Reports\ _
Master Benchmark Data Sheet.xlsx")
End Sub
* Follow Doug's answer if the workbook is already open. For the sake of making this answer as complete as possible, I'm including my comment on his answer:
Why do I have to "set" it?
Set
is how VBA assigns object variables. Since a Range
and a Workbook
/Worksheet
are objects, you must use Set
with these.
Google recommend that you don't use any of them, source.
There is no need to use entity references like
&mdash
,&rdquo
, or☺
, assuming the same encoding (UTF-8) is used for files and editors as well as among teams.
Is there a reason you can't simply use "
?

Update C#8.0, 2019: Nullable reference types
C#8.0 introduces nullable reference types and non-nullable reference types. So only nullable reference types must be checked to avoid a NullReferenceException.
If you have not initialized a reference type, and you want to set or read one of its properties, it will throw a NullReferenceException.
Example:
Person p = null;
p.Name = "Harry"; // NullReferenceException occurs here.
You can simply avoid this by checking if the variable is not null:
Person p = null;
if (p!=null)
{
p.Name = "Harry"; // Not going to run to this point
}
To fully understand why a NullReferenceException is thrown, it is important to know the difference between value types and [reference types][3].
So, if you're dealing with value types, NullReferenceExceptions can not occur. Though you need to keep alert when dealing with reference types!
Only reference types, as the name is suggesting, can hold references or point literally to nothing (or 'null'). Whereas value types always contain a value.
Reference types (these ones must be checked):
Value types (you can simply ignore these ones):
You have extra brackets in Hours property;

This may be a long shot, but Crystal Reports for Eclipse is free. I'm not sure if it will work, but if all you need is to edit some static text, you could get that version of CR and get the job done.
Just correct Google play services dependencies:
You are including all play services in your project. Only add those you want.
For example , if you are using only maps and g+ signin, than change
compile 'com.google.android.gms:play-services:8.1.0'
to
compile 'com.google.android.gms:play-services-maps:8.1.0'
compile 'com.google.android.gms:play-services-plus:8.1.0'
From the doc :
In versions of Google Play services prior to 6.5, you had to compile the entire package of APIs into your app. In some cases, doing so made it more difficult to keep the number of methods in your app (including framework APIs, library methods, and your own code) under the 65,536 limit.
From version 6.5, you can instead selectively compile Google Play service APIs into your app. For example, to include only the Google Fit and Android Wear APIs, replace the following line in your build.gradle file:
compile 'com.google.android.gms:play-services:8.3.0'
with these lines:compile 'com.google.android.gms:play-services-fitness:8.3.0'
compile 'com.google.android.gms:play-services-wearable:8.3.0'
@David Conrad solution is the fastest I tried using the Normalizer, but it does have a bug. It basically strips characters which are not accents, for example Chinese characters and other letters like æ, are all stripped. The characters that we want to strip are non spacing marks, characters which don't take up extra width in the final string. These zero width characters basically end up combined in some other character. If you can see them isolated as a character, for example like this `, my guess is that it's combined with the space character.
public static String flattenToAscii(String string) {
char[] out = new char[string.length()];
String norm = Normalizer.normalize(string, Normalizer.Form.NFD);
int j = 0;
for (int i = 0, n = norm.length(); i < n; ++i) {
char c = norm.charAt(i);
int type = Character.getType(c);
//Log.d(TAG,""+c);
//by Ricardo, modified the character check for accents, ref: http://stackoverflow.com/a/5697575/689223
if (type != Character.NON_SPACING_MARK){
out[j] = c;
j++;
}
}
//Log.d(TAG,"normalized string:"+norm+"/"+new String(out));
return new String(out);
}
As a workaround, you may use...
Windows Powershell ISE
As the Powershell script editor does not seems to have a buffer limitation in its read-eval-print-loop part (the "blue" part). And with Powershell you may execute DOS commands as well.
PS. I understand this answer is a bit aside the original question, however I believe it is good to mention as it is a good workaround.
if you want to escape double quote in JSON use \\ to escape it.
example if you want to create json of following javascript object
{time: '7 "o" clock'}
then you must write in following way
'{"time":"7 \\"o\\" clock"}'
if we parse it using JSON.parse()
JSON.parse('{"time":"7 \\"o\\" clock"}')
result will be
{time: "7 "o" clock"}

I just installed Drony, is not shareware and it does no require root on cellphone with Android 3.x or above
https://play.google.com/store/apps/details?id=org.sandroproxy.drony

this will give output as '11/02/2019 11:08:26'
