The @
disables echo for that one command. Without it, the echo start eclipse.exe
line would print both the intended start eclipse.exe
and the echo start eclipse.exe
line.
The echo off
turns off the by-default command echoing.
So @echo off
silently turns off command echoing, and only output the batch author intended to be written is actually written.
The answers here match up to the question, but I'm going to answer the question you didn't ask. "Should I use truncate or delete?" If you are removing all rows from a table, you'll typically want to truncate, since it's much much faster. Why is it much faster? At least in the case of Oracle, it resets the high water mark. This is basically a dereferencing of the data and allows the db to reuse it for something else.
I personally wouldn't try grabbing it inside of the view. I'm not amazing at Laravel, but I would imagine you'd need to send your route to a controller, and then within the controller, pass the variable (via an array) into your view, using something like $url = Request::url();
.
One way of doing it anyway.
EDIT: Actually look at the method above, probably a better way.
Whatever you return from a promise will be wrapped into a promise to be unwrapped at the next .then()
stage.
It becomes interesting when you need to return one or more promise(s) alongside one or more synchronous value(s) such as;
Promise.resolve([Promise.resolve(1), Promise.resolve(2), 3, 4])
.then(([p1,p2,n1,n2]) => /* p1 and p2 are still promises */);
In these cases it would be essential to use Promise.all()
to get p1
and p2
promises unwrapped at the next .then()
stage such as
Promise.resolve(Promise.all([Promise.resolve(1), Promise.resolve(2), 3, 4]))
.then(([p1,p2,n1,n2]) => /* p1 is 1, p2 is 2, n1 is 3 and n2 is 4 */);
This happens when your table structure and model class no longer in sync. You need to update the table structure according to the model class or vice versa -- this is when your data is important and must not be deleted. If your data structure has changed and the data isn't important to you, you can use the DropCreateDatabaseIfModelChanges
feature (formerly known as 'RecreateDatabaseIfModelChanges
' feature) by adding the following code in your Global.asax.cs:
Database.SetInitializer<MyDbContext>(new DropCreateDatabaseIfModelChanges<MyDbContext>());
Run your application again.
As the name implies, this will drop your database and recreate according to your latest model class (or classes) -- provided you believe the table structure definitions in your model classes are the most current and latest; otherwise change the property definitions of your model classes instead.
You can add header "Content-Type: text/html; charset=UTF-8" to your message body.
$headers = "Content-Type: text/html; charset=UTF-8";
If you use native mail()
function $headers array will be the 4th parameter
mail($to, $subject, $message, $headers)
If you user PEAR Mail::factory() code will be:
$smtp = Mail::factory('smtp', $params);
$mail = $smtp->send($to, $headers, $body);
Class.forName(nameString).newInstance();
Use Apache commons StringUtils.join()
. It takes an array, as a parameter (and also has overloads for Iterable
and Iterator
parameters) and calls toString()
on each element (if it is not null) to get each elements string representation. Each elements string representation is then joined into one string with a separator in between if one is specified:
String joinedString = StringUtils.join(new Object[]{"a", "b", 1}, "-");
System.out.println(joinedString);
Produces:
a-b-1
Bind the button, this is done with jQuery:
$("#my-table input[type='button']").click(function(){
var parameter = $(this).val();
window.location = "http://yoursite.com/page?variable=" + parameter;
});
crcany will generate efficient C code for any CRC, and includes a library of over one hundred known CRC definitions.
Efficient CRC code uses tables instead of bit-wise calculations. crcany generates both byte-wise routines and word-wise routines, the latter tuned to the architecture they are generated on. Word-wise is the fastest. Byte-wise is still much faster than bit-wise, but the implementation is more easily portable over architectures.
You do not seem to have a protocol definition with a specific CRC definition that you need to match. In this case, you can pick any 16-bit CRC in the catalog, and you will get good performance.
If you have a relatively low bit error rate, e.g. single digit number of errors per packet, and you want to maximize your error detection performance, you would need to look at the packet size you are applying the CRC to, assuming that that is constant or bounded, and look at the performance of the best polynomials in Philip Koopman's extensive research. The classic CRCs, such as the CCITT/Kermit 16-bit CRC or the X.25 16-bit CRC are not the best performers.
One of the good 16-bit performers in Koopman's tables that is also in the catalog of CRCs used in practice is CRC-16/DNP. It has very good performance detecting up to 6-bit errors in a packet. Following is the code generated by crcany for that CRC definition. This code assumes a little-endian architecture for the word-wise calculation, e.g. Intel x86 and x86-64, and it assumes that uintmax_t
is 64 bits. crcany can be used to generate alternative code for big-endian and other word sizes.
crc16dnp.h:
// The _bit, _byte, and _word routines return the CRC of the len bytes at mem,
// applied to the previous CRC value, crc. If mem is NULL, then the other
// arguments are ignored, and the initial CRC, i.e. the CRC of zero bytes, is
// returned. Those routines will all return the same result, differing only in
// speed and code complexity. The _rem routine returns the CRC of the remaining
// bits in the last byte, for when the number of bits in the message is not a
// multiple of eight. The low bits bits of the low byte of val are applied to
// crc. bits must be in 0..8.

Last revision merged from trunk to branch can be found by running this command inside the working copy directory:
svn log -v --stop-on-copy
In C++ it is done like this:
#define LOCAL_PI 3.1415926535897932385
double ToRadians(double degrees)
{
double radians = degrees * LOCAL_PI / 180;
return radians;
}
double DirectDistance(double lat1, double lng1, double lat2, double lng2)
{
double earthRadius = 3958.75;
double dLat = ToRadians(lat2-lat1);
double dLng = ToRadians(lng2-lng1);
double a = sin(dLat/2) * sin(dLat/2) +
cos(ToRadians(lat1)) * cos(ToRadians(lat2)) *
sin(dLng/2) * sin(dLng/2);
double c = 2 * atan2(sqrt(a), sqrt(1-a));
double dist = earthRadius * c;
double meterConversion = 1609.00;
return dist * meterConversion;
}
Just another approach:
1) Alt+Up and Alt+Down (or Alt+Down and Alt+Up, order does not matter)
2) Ctrl+C
But of course vim's "yy" is the fastest :)
System.Uri.EscapeUriString() didn't seem to do anything, but System.Uri.EscapeDataString() worked for me.
Experienced the same error, for me it was caused because on my Mac I have changed the DocumentRoot to my users Sites directory.
To fix it, I ran the recursive command to ensure that the Apache service has read permissions.
sudo chmod -R 755 ~/Sites

this php function explode string by newline
Attention : new line in Windows is \r\n and in Linux and Unix is \n
this function change all new lines to linux mode then split it.
pay attention that empty lines will be ignored
function splitNewLine($text) {
$code=preg_replace('/\n$/','',preg_replace('/^\n/','',preg_replace('/[\r\n]+/',"\n",$text)));
return explode("\n",$code);
}
example
$a="\r\n\r\n\n\n\r\rsalam\r\nman khobam\rto chi\n\rche khabar\n\r\n\n\r\r\n\nbashe baba raftam\r\n\r\n\r\n\r\n";
print_r( splitNewLine($a) );
output
Array
(
[0] => salam
[1] => man khobam
[2] => to chi
[3] => che khabar
[4] => bashe baba raftam
)
I got a lot of trouble trying to reload something inside Sublime Text, but finally I could wrote this utility to reload modules on Sublime Text based on the code sublime_plugin.py
uses to reload modules.
This below accepts you to reload modules from paths with spaces on their names, then later after reloading you can just import as you usually do.
def reload_module(full_module_name):
"""
Assuming the folder `full_module_name` is a folder inside some
folder on the python sys.path, for example, sys.path as `C:/`, and
you are inside the folder `C:/Path With Spaces` on the file
`C:/Path With Spaces/main.py` and want to re-import some files on
the folder `C:/Path With Spaces/tests`
@param full_module_name the relative full path to the module file
you want to reload from a folder on the
python `sys.path`
"""
import imp
import sys
import importlib
if full_module_name in sys.modules:
module_object = sys.modules[full_module_name]
module_object = imp.reload( module_object )
else:
importlib.import_module( full_module_name )
def run_tests():
print( "\n\n" )
reload_module( "Path With Spaces.tests.semantic_linefeed_unit_tests" )
reload_module( "Path With Spaces.tests.semantic_linefeed_manual_tests" )
from .tests import semantic_linefeed_unit_tests
from .tests import semantic_linefeed_manual_tests
semantic_linefeed_unit_tests.run_unit_tests()
semantic_linefeed_manual_tests.run_manual_tests()
if __name__ == "__main__":
run_tests()
If you run for the first time, this should load the module, but if later you can again the method/function run_tests()
it will reload the tests files. With Sublime Text (Python 3.3.6
) this happens a lot because its interpreter never closes (unless you restart Sublime Text, i.e., the Python3.3
interpreter).
In Web-"MVC" you can do whatever you please.
The original concept (1) described the model as the business logic. It should represent the application state and enforce some data consistency. That approach is often described as "fat model".
Most PHP frameworks follow a more shallow approach, where the model is just a database interface. But at the very least these models should still validate the incoming data and relations.
Either way, you're not very far off if you separate the SQL stuff or database calls into another layer. This way you only need to concern yourself with the real data/behaviour, not with the actual storage API. (It's however unreasonable to overdo it. You'll e.g. never be able to replace a database backend with a filestorage if that wasn't designed ahead.)
You’re looking for urllib.parse.urlencode
import urllib.parse
params = {'username': 'administrator', 'password': 'xyz'}
encoded = urllib.parse.urlencode(params)
# Returns: 'username=administrator&password=xyz'
You are declaring a local variable, not a class variable. To set an instance variable (attribute), use
class Example(object):
def the_example(self):
self.itsProblem = "problem" # <-- remember the 'self.'
theExample = Example()
theExample.the_example()
print(theExample.itsProblem)
To set a class variable (a.k.a. static member), use
class Example(object):
def the_example(self):
Example.itsProblem = "problem"
# or, type(self).itsProblem = "problem"
# depending what you want to do when the class is derived.
My solution is to have a general extension for string to int conversion.
extension String {
// default: it is a number suitable for your project if the string is not an integer
func toInt(default: Int) -> Int {
if let result = Int(self) {
return result
}
else {
return default
}
}
}
I've tried this 2 options (read/write), with plain objects, array of objects (150 objects), Map:
Option1:
FileOutputStream fos = context.openFileOutput(fileName, Context.MODE_PRIVATE);
ObjectOutputStream os = new ObjectOutputStream(fos);
os.writeObject(this);
os.close();
Option2:
SharedPreferences mPrefs=app.getSharedPreferences(app.getApplicationInfo().name, Context.MODE_PRIVATE);
SharedPreferences.Editor ed=mPrefs.edit();
Gson gson = new Gson();
ed.putString("myObjectKey", gson.toJson(objectToSave));
ed.commit();
Option 2 is twice quicker than option 1
The option 2 inconvenience is that you have to make specific code for read:
Gson gson = new Gson();
JsonParser parser=new JsonParser();
//object arr example
JsonArray arr=parser.parse(mPrefs.getString("myArrKey", null)).getAsJsonArray();
events=new Event[arr.size()];
int i=0;
for (JsonElement jsonElement : arr)
events[i++]=gson.fromJson(jsonElement, Event.class);
//Object example
pagination=gson.fromJson(parser.parse(jsonPagination).getAsJsonObject(), Pagination.class);
You can just pass your URL,
NSURL *url = [NSURL URLWithString:@"http://www.myurl.com/1.png"];
NSURLSessionTask *task = [[NSURLSession sharedSession] dataTaskWithURL:url completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
if (data) {
UIImage *image = [UIImage imageWithData:data];
if (image) {
dispatch_async(dispatch_get_main_queue(), ^{
yourimageview.image = image;
});
}
}
}];
[task resume];
Another answer here also mentions since 2012 you can remove Remove cached login via How to remove cached server names from the Connect to Server dialog?. Just confirmed this delete in MRU list works fine in 2016 and 2017.
SQL Server Management Studio 2017 delete the file
C:\Users\%username%\AppData\Roaming\Microsoft\SQL Server Management Studio\14.0\SqlStudio.bin
SQL Server Management Studio 2016 delete the file
C:\Users\%username%\AppData\Roaming\Microsoft\SQL Server Management Studio\13.0\SqlStudio.bin
SQL Server Management Studio 2014 delete the file
C:\Users\%username%\AppData\Roaming\Microsoft\SQL Server Management Studio\12.0\SqlStudio.bin
SQL Server Management Studio 2012 delete the file
C:\Users\%username%\AppData\Roaming\Microsoft\SQL Server Management Studio\11.0\SqlStudio.bin
SQL Server Management Studio 2008 delete the file C:\Users\%username%\AppData\Roaming\Microsoft\Microsoft SQL Server\100\Tools\Shell\SqlStudio.bin
SQL Server Management Studio 2005 delete the file – same as above answer but the Vista path.
C:\Users\%username%\AppData\Roaming\Microsoft\Microsoft SQL Server\90\Tools\Shell\mru.dat
These are profile paths for Vista / 7 / 8.
EDIT:
Note, AppData
is a hidden folder. You need to show hidden folders in explorer.
EDIT: You can simply press delete from the Server / User name drop down (confirmed to be working for SSMS v18.0). Original source from https://blog.sqlauthority.com/2013/04/17/sql-server-remove-cached-login-from-ssms-connect-dialog-sql-in-sixty-seconds-049/ which mentioned that this feature is available since 2012!
The ModuleNotFoundError
has been introduced in python 3.6 and can be used for this purpose
try:
import eggs
except ModuleNotFoundError:
# Error handling
pass
The error is raised when a module or one of its parents cannot be found. So
try:
import eggs.sub
except ModuleNotFoundError as err:
# Error handling
print(err)
would print a message that looks like No module named 'eggs'
if the eggs
module cannot be found; but would print something like No module named 'eggs.sub'
if only the sub
module couldn't be found but the eggs
package could be found.
See the documentation of the import system for more info on the ModuleNotFoundError
Try this:
\?(.*)
The parentheses are a capturing group that you can use to extract the part of the string you are interested in.
If the string can contain new lines you may have to use the "dot all" modifier to allow the dot to match the new line character. Whether or not you have to do this, and how to do this, depends on the language you are using. It appears that you forgot to mention the programming language you are using in your question.
Another alternative that you can use if your language supports fixed width lookbehind assertions is:
(?<=\?).*

True
is always True
, so while True
will loop forever.
The while
keyword takes an expression, and loops while the expression is true. True
is an expression that is always true.
As a possibly clarifying example, consider the following:
a = 1
result = a == 1
Here, a == 1
will return True
, and hence put True
into result
. Hence,
a = 1
while a == 1:
...
is equivalent to:
while True:
...
provided you don't alter the value of a
inside the while
loop.
Let's create the dataframe in question
df_test = spark.createDataFrame(
[
(1, 5),
(2, 9),
(3, 3),
(4, 1),
],
['mvv', 'count']
)
df_test.show()
Which gives
+---+-----+
|mvv|count|
+---+-----+
| 1| 5|
| 2| 9|
| 3| 3|
| 4| 1|
+---+-----+
and then apply rdd.flatMap(f).collect() to get the list
test_list = df_test.select("mvv").rdd.flatMap(list).collect()
print(type(test_list))
print(test_list)
which gives
<type 'list'>

The docs for java.io.Serializable
are probably about as good an explanation as you'll get:
The serialization runtime associates with each serializable class a version number, called a
serialVersionUID
, which is used during deserialization to verify that the sender and receiver of a serialized object have loaded classes for that object that are compatible with respect to serialization. If the receiver has loaded a class for the object that has a differentserialVersionUID
than that of the corresponding sender's class, then deserialization will result in anInvalidClassException
. A serializable class can declare its ownserialVersionUID
explicitly by declaring a field namedserialVersionUID
that must be static, final, and of typelong
:
ANY-ACCESS-MODIFIER static final long serialVersionUID = 42L;
If a serializable class does not explicitly declare a
serialVersionUID
, then the serialization runtime will calculate a defaultserialVersionUID
value for that class based on various aspects of the class, as described in the Java(TM) Object Serialization Specification. However, it is strongly recommended that all serializable classes explicitly declareserialVersionUID
values, since the defaultserialVersionUID
computation is highly sensitive to class details that may vary depending on compiler implementations, and can thus result in unexpectedInvalidClassExceptions
during deserialization. Therefore, to guarantee a consistentserialVersionUID
value across different java compiler implementations, a serializable class must declare an explicitserialVersionUID
value. It is also strongly advised that explicitserialVersionUID
declarations use the private modifier where possible, since such declarations apply only to the immediately declaring class —serialVersionUID
fields are not useful as inherited members.

Following the JSON-P 1.0 specs (JSR-353) a more current solution for a given JsonStructure
(JsonObject
or JsonArray
) could look like this:
import java.io.StringWriter;
import java.util.HashMap;
import java.util.Map;
import javax.json.Json;
import javax.json.JsonStructure;
import javax.json.JsonWriter;
import javax.json.JsonWriterFactory;
import javax.json.stream.JsonGenerator;
public class PrettyJson {
private static JsonWriterFactory FACTORY_INSTANCE;
public static String toString(final JsonStructure status) {
final StringWriter stringWriter = new StringWriter();
final JsonWriter jsonWriter = getPrettyJsonWriterFactory()
.createWriter(stringWriter);
jsonWriter.write(status);
jsonWriter.close();
return stringWriter.toString();
}
private static JsonWriterFactory getPrettyJsonWriterFactory() {
if (null == FACTORY_INSTANCE) {
final Map<String, Object> properties = new HashMap<>(1);
properties.put(JsonGenerator.PRETTY_PRINTING, true);
FACTORY_INSTANCE = Json.createWriterFactory(properties);
}
return FACTORY_INSTANCE;
}
}
You can use the inbuilt function max()
with multiple arguments:
print max(1, 2, 3)
or a list:
list = [1, 2, 3]
print max(list)
or in fact anything iterable.
If they all have the same extension (for example .jpg), you can use this:
for picture in *.jpg ; do
echo "the next file is $picture"
done
(This solution also works if the filename has spaces)
Just:
dt = datetimeObject.strftime(format) # format = your datetime format ex) '%Y %d %m'
dt = datetime.datetime.strptime(dt,format)
So do this:
start_time = challenge.datetime_start.strftime('%Y %d %m %H %M %S')
start_time = datetime.datetime.strptime(start_time,'%Y %d %m %H %M %S')
end_time = challenge.datetime_end.strftime('%Y %d %m %H %M %S')
end_time = datetime.datetime.strptime(end_time,'%Y %d %m %H %M %S')
and then use start_time
and end_time
This is a mistake:
m.check(side);
That code has to go inside a function. Your class definition can only contain declarations and functions.
Classes don't "run", they provide a blueprint for how to make an object.
The line Message m;
means that an Orderbook
will contain Message
called m
, if you later create an Orderbook
.
I would prefer AssertJ for this.
assertThatExceptionOfType(ExpectedException.class)
.isThrownBy(() -> {
// method call
}).withMessage("My message");
You want a form that self submits? Then you just leave the "action" parameter blank.
like:
<form method="post" action="" />
If you want to process the form with this page, then make sure that you have some mechanism in the form or session data to test whether it was properly submitted and to ensure you're not trying to process the empty form.
You might want another mechanism to decide if the form was filled out and submitted but is invalid. I usually use a hidden input field that matches a session variable to decide whether the user has clicked submit or just loaded the page for the first time. By giving a unique value each time and setting the session data to the same value, you can also avoid duplicate submissions if the user clicks submit twice.
I've just spent a while trying to get this to work an have a written a Ruby gem that accesses the API. You can read more on it's project page.

Just to clarify in human language what the error is trying to tell you:
You cannot create a repository in this folder which already tracked in the main repository.
For example: You have a theme folder called AwesomeTheme
that's a dedicated repository, you try do dump it directly into your main repository like git submodule add sites/themes
and you get this "AwesomeTheme" index already exists
.
You just need to make sure there isn't already a sites/themes/AwesomeTheme
in the main repository's version tracking so the submodule can be created there.
So to fix, in your main repository if you have an empty sites/theme/AwesomeTheme
directory then remove it. If you have already made commits with the sites/theme/AwesomeTheme
directory in your main repository you need to purge all history of it with a command like this:
git filter-branch --index-filter \
'git rm -r --cached --ignore-unmatch sites/theme/AwesomeTheme' HEAD
Now you can run git submodule add [email protected] sites/themes/AwesomeTheme
Since the main repository has never seen anything (a.k.a index'd) in sites/themes/AwesomeTheme
before, it can now create it.
If you're not too attached to your current workspace you can create a new workspace, follow BalusC's steps for server creation, and recreate your project in the new workspace.
I got the same error after installing Eclipse Java EE IDE for Web Developers(Juno) but using the workspace of a much older Eclipse installation. When I created a new workspace I was able to get my Tomcat server running without this error.
I had the same problem and the issue was that my child component had an @input

So I just needed to change from:
<my-component [formControl]="formControl"><my-component/>
to:
<my-component [control]="control"><my-component/>
ts:

I assume you are using Series.plot() to plot your data. If you look at the docs for Series.plot() here:
http://pandas.pydata.org/pandas-docs/dev/generated/pandas.Series.plot.html
there is no color parameter listed where you might be able to set the colors for your bar graph.
However, the Series.plot() docs state the following at the end of the parameter list:
kwds : keywords
Options to pass to matplotlib plotting method
What that means is that when you specify the kind argument for Series.plot() as bar, Series.plot() will actually call matplotlib.pyplot.bar(), and matplotlib.pyplot.bar() will be sent all the extra keyword arguments that you specify at the end of the argument list for Series.plot().
If you examine the docs for the matplotlib.pyplot.bar() method here:
http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.bar
..it also accepts keyword arguments at the end of it's parameter list, and if you peruse the list of recognized parameter names, one of them is color, which can be a sequence specifying the different colors for your bar graph.
Putting it all together, if you specify the color keyword argument at the end of your Series.plot() argument list, the keyword argument will be relayed to the matplotlib.pyplot.bar() method. Here is the proof:
import pandas as pd
import matplotlib.pyplot as plt
s = pd.Series(
[5, 4, 4, 1, 12],
index = ["AK", "AX", "GA", "SQ", "WN"]
)
#Set descriptions:
plt.title("Total Delay Incident Caused by Carrier")
plt.ylabel('Delay Incident')
plt.xlabel('Carrier')
#Set tick colors:
ax = plt.gca()
ax.tick_params(axis='x', colors='blue')
ax.tick_params(axis='y', colors='red')
#Plot the data:
my_colors = 'rgbkymc' #red, green, blue, black, etc.
pd.Series.plot(
s,
kind='bar',
color=my_colors,
)
plt.show()
Note that if there are more bars than colors in your sequence, the colors will repeat.

Seen a lot of the answers, but the correct one is to provide the full options for the header function call as per the php manual
void header ( string $string [, bool $replace = true [, int $http_response_code ]] )
If you invoke with

the normal behavior of HTTP 403 as configured with Apache or any other server would follow.
Neither one. Use final class for Constants

You have to download the Intel® Hardware Accelerated Execution Manager. Then you will get this message:
Starting emulator for AVD 'test' emulator: device fd:740 HAX is working and emulator runs in fast virt mode
What you should do, is put CallFunction
into *.cpp file, where you include B.h.
After edit, files will look like:
#pragma once //or other specific to compiler...
using namespace std;
class A
{
public:
void CallFunction ();
};
class B: public A
{
public:
virtual void bFunction()
{
//stuff done here
}
};
#include "B.h"
void A::CallFunction(){
//use B object here...
}
Referencing to your explanation, that you have tried to change B b; into pointer- it would be okay, if you wouldn't use it in that same place. You can use pointer of undefined class(but declared), because ALL pointers have fixed byte size(4), so compiler doesn't have problems with that. But it knows nothing about the object they are pointing to(simply: knows the size/boundary, not the content).
So as long as you are using the knowledge, that all pointers are same size, you can use them anywhere. But if you want to use the object, they are pointing to, the class of this object must be already defined and known by compiler.
And last clarification: objects may differ in size, unlike pointers. Pointer is a number/index, which indicates the place in RAM, where something is stored(for example index: 0xf6a7b1).

It will download packages and their dependencies to a directory (current working directory by default), but it performs the additional step of converting any source packages to wheels.
It conveniently supports requirements files:
pip wheel -r requirements.txt -w .\outputdir
Add the --no-deps
argument if you only want the specifically requested packages:
pip wheel mypackage -w .\outputdir --no-deps

First, you declared $db outside the function. If you want to use it inside the function, you should put this at the begining of your function code:
global $db;
And I guess, when you wrote:
if($result->num_rows){
return (mysqli_result($query, 0) == 1) ? true : false;
what you really wanted was:
if ($result->num_rows==1) { return true; } else { return false; }
Something like this:
import matplotlib.pyplot as plt
... code for plot 1 ...
plt.show()
... code for plot 2...
plt.show()
Note that this will also work if you are using the seaborn
package for plotting:
import matplotlib.pyplot as plt
import seaborn as sns
sns.barplot(... code for plot 1 ...) # plot 1
plt.show()
sns.barplot(... code for plot 2 ...) # plot 2
plt.show()
I think the easiest way to think about this variable like input parameter in lambda expression in C#. I.e. $_
is similar to x
in x => Console.WriteLine(x)
anonymous function in C#. Consider following examples:
PowerShell:
1,2,3 | ForEach-Object {Write-Host $_}
Prints:
1
2
3
or
1,2,3 | Where-Object {$_ -gt 1}
Prints:
2
3
And compare this with C# syntax using LINQ:
var list = new List<int> { 1, 2, 3 };
list.ForEach( _ => Console.WriteLine( _ ));
Prints:
1
2
3
or
list.Where( _ => _ > 1)
.ToList()
.ForEach(s => Console.WriteLine(s));
Prints:
2
3
Update your working copy to the selected revision. Useful if you want to have your working copy reflect a time in the past, or if there have been further commits to the repository and you want to update your working copy one step at a time. It is best to update a whole directory in your working copy, not just one file, otherwise your working copy could be inconsistent. This is used to test a specific rev purpose, if your test has done, you can use this command to test another rev or use SVN Update to get HEAD
If you want to undo an earlier change permanently, use Revert to this revision instead.
-- from TSVN help doc
If you Update your working copy to an earlier rev, this is only affect your own working copy, after you do some change, and want to commit, you will fail,TSVN will alert you to update your WC to latest revision first If you Revert to a rev, you can commit to repository.everyone will back to the rev after they do an update.
FWIW, Codegear C++Builder doesn't destruct in the expected order according to the standard.
C:\> sample.exe 1 2
Created in foo
Created in if
Destroyed in foo
Destroyed in if
... which is another reason not to rely on the destruction order!
In C++11, to_string is finally added to the standard.

Look at the source code in Modernizer, this section:
// Change `no-js` to `js` (independently of the `enableClasses` option)
// Handle classPrefix on this too
if (Modernizr._config.enableJSClass) {
var reJS = new RegExp('(^|\\s)' + classPrefix + 'no-js(\\s|$)');
className = className.replace(reJS, '$1' + classPrefix + 'js$2');
}
So basically it search for classPrefix + no-js
class and replace it with classPrefix + js
.
And the use of that, is styling differently if JavaScript not running in the browser.
I think it's better to use the chrome toggle device toolbar with the chrome inspector. It provides you a user agent switch along with responsive mode.
Just use this:
List<SomeBean> newList = new ArrayList<SomeBean>(otherList);
Note: still not thread safe, if you modify otherList

) a CopyOnWriteArrayList
, for instance -- or use a lock primitive, such as ReentrantReadWriteLock to serialize read/write access to whatever lists are concurrently accessed.

The obvious subtext of this question is:
why can't you just use
==
to check if two strings are the same?
Perl doesn't have distinct data types for text vs. numbers. They are both represented by the type "scalar". Put another way, strings are numbers if you use them as such.
if ( 4 == "4" ) { print "true"; } else { print "false"; }
true
if ( "4" == "4.0" ) { print "true"; } else { print "false"; }
true
print "3"+4
7
Since text and numbers aren't differentiated by the language, we can't simply overload the ==
operator to do the right thing for both cases. Therefore, Perl provides eq
to compare values as text:
if ( "4" eq "4.0" ) { print "true"; } else { print "false"; }
false
if ( "4.0" eq "4.0" ) { print "true"; } else { print "false"; }
true
In short:
==
or !=
, to compare two operands as numberseq
or ne
, to compare two operands as textThere are many other functions and operators that can be used to compare scalar values, but knowing the distinction between these two forms is an important first step.

The answer is "not really".
CSS isn't a functional layer. It doesn't have any awareness of what happens or when. It's used simply to add a presentational layer to different "flags" (classes, ids, states).
By default, CSS/DOM does not provide any kind of "on load" state for CSS to use. If you wanted/were able to use JavaScript, you'd allocate a class to body
or something to activate some CSS.
That being said, you can create a hack for that. I'll give an example here, but it may or may not be applicable to your situation.
We're operating on the assumption that "close" is "good enough":
<html>
<head>
<!-- Reference your CSS here... -->
</head>
<body>
<!-- A whole bunch of HTML here... -->
<div class="onLoad">OMG, I've loaded !</div>
</body>
</html>
Here's an excerpt of our CSS stylesheet:
.onLoad
{
-webkit-animation:bounceIn 2s;
}
We're also on the assumption that modern browsers render progressively, so our last element will render last, and so this CSS will be activated last.

Perl really only has three types: scalars, arrays, and hashes. And even that distinction is arguable. ;) The way each variable is treated depends on what you do with it:

5.43.4
% perl -e "print '5.4' + '3.4';"

I'm not sure how exactly you want the formatting to look like, but you could start with a function like this:
def pretty(d, indent=0):
for key, value in d.items():
print('\t' * indent + str(key))
if isinstance(value, dict):
pretty(value, indent+1)
else:
print('\t' * (indent+1) + str(value))
If you want to check if both objects have the same properties name, you can do this:
function hasSameProps( obj1, obj2 ) {
return Object.keys( obj1 ).every( function( prop ) {
return obj2.hasOwnProperty( prop );
});
}
var obj1 = { prop1: 'hello', prop2: 'world', prop3: [1,2,3,4,5] },
obj2 = { prop1: 'hello', prop2: 'world', prop3: [1,2,3,4,5] };
console.log(hasSameProps(obj1, obj2));
In this way you are sure to check only iterable and accessible properties of both the objects.
EDIT - 2013.04.26:
The previous function can be rewritten in the following way:
function hasSameProps( obj1, obj2 ) {
var obj1Props = Object.keys( obj1 ),
obj2Props = Object.keys( obj2 );
if ( obj1Props.length == obj2Props.length ) {
return obj1Props.every( function( prop ) {
return obj2Props.indexOf( prop ) >= 0;
});
}
return false;
}
In this way we check that both the objects have the same number of properties (otherwise the objects haven't the same properties, and we must return a logical false) then, if the number matches, we go to check if they have the same properties.
Bonus
A possible enhancement could be to introduce also a type checking to enforce the match on every property.

There are many ways to get a path. See CurrentDirrectory mentioned. Also, you can get the full file name of your application by using Assembly.GetExecutingAssembly().Location and then use Path class to get a directory name.
If a directory has spaces in, put quotes around it. This includes the program you're calling, not just the arguments

The number of results can (theoretically) be greater than the range of an integer. I would refactor the code and work with the returned long value instead.

Now that the box has been added to Vagrant, we need to configure our project to use it as a base. Open the Vagrantfile and change the contents to the following:
Vagrant.configure("2") do |config| config.vm.box = "hashicorp/precise32" end
Setting your branch to exactly match the remote branch can be done in two steps:
git fetch origin
git reset --hard origin/master
Update @2020 (if you have main
branch instead of master
in remote repo)
git fetch origin
git reset --hard origin/main
If you want to save your current branch's state before doing this (just in case), you can do:
git commit -a -m "Saving my work, just in case"
git branch my-saved-work
Now your work is saved on the branch "my-saved-work" in case you decide you want it back (or want to look at it later or diff it against your updated branch).
Note that the first example assumes that the remote repo's name is "origin" and that the branch named "master" in the remote repo matches the currently checked-out branch in your local repo.
BTW, this situation that you're in looks an awful lot like a common case where a push has been done into the currently checked out branch of a non-bare repository. Did you recently push into your local repo? If not, then no worries -- something else must have caused these files to unexpectedly end up modified. Otherwise, you should be aware that it's not recommended to push into a non-bare repository (and not into the currently checked-out branch, in particular).
I have faced the similar issue and fixed by copying the missing Jar files in to .M2 Path,
For example: if you see the error message as Missing artifact tws:axis-client:jar:8.7
then you have to download "axis-client-8.7.jar" file and paste the same in to below location will resolve the issue.
C:\Users\UsernameXXX.m2\repository\tws\axis-client\8.7(Paste axis-client-8.7.jar).
finally, right click on project->Maven->Update Project...Thats it.
happy coding.
Here's an example with a Windows path:
docker run -P -it --name organizr --mount src="/c/Users/MyUserName/AppData/Roaming/DockerConfigs/Organizr",dst=/config,type=bind organizrtools/organizr-v2:latest
As a side note, during all of this hair pulling, having to wrestle with figuring out, and retyping paths over and over and over again, I decided to whip up a small AutoHotkey
script to convert a Windows path to a "Docker Windows" formatted path. This way all I have to do is copy any Windows path that I want to use as a mount point to the clipboard, press the "Apps Key" on the keyboard, and it'll format it into a path format that Docker appreciates.
For example:
Copy this to your clipboard:
C:\Users\My PC\AppData\Roaming\DockerConfigs\Organizr
press the Apps Key
while the cursor is where you want it on the command-line, and it'll paste this there:
"/c/Users/My PC/AppData/Roaming/DockerConfigs/Organizr"
Saves a lot to time for me. Here it is for anyone else who may find it useful.

;
; Docker Utility: Convert a Windows Formatted Path to a Docker Formatter Path
; Useful for (example) when mounting Windows volumes via the command-line.
;
; By: J. Scott Elblein
; Version: 1.0
; Date: 2/5/2019
;
; Usage: Cut or Copy the Windows formatted path to the clipboard, press the AppsKey on your keyboard
; (usually right next to the Windows Key), it'll format it into a 'docker path' and enter it
; into the active window. Easy example usage would be to copy your intended volume path via
; Explorer, place the cursor after the "-v" in your Docker command, press the Apps Key and
; then it'll place the formatted path onto the line for you.
;
; TODO:: I may or may not add anything to this depending on needs. Some ideas are:
;
; - Add a tray menu with the ability to do some things, like just replace the unformatted path
; on the clipboard with the formatted one rather than enter it automatically.
; - Add 'smarter' handling so the it first confirms that the clipboard text is even a path in
; the first place. (would need to be able to handle Win + Mac + Linux)
; - Add command-line handling so the script doesn't need to always be in the tray, you could
; just pass the Windows path to the script, have it format it, then paste and close.
; Also, could have it just check for a path on the clipboard upon script startup, if found
; do it's job, then exit the script.
; - Add an 'all-in-one' action, to copy the selected Windows path, and then output the result.
; - Whatever else comes to mind.

You can use this library https://github.com/cbeust/klaxon
Klaxon is a lightweight library to parse JSON in Kotlin.
You should be able to access the document in the IFRAME using the following code:
document.getElementById('myframe').contentWindow.document
However, you will not be able to do this if the page in the frame is loaded from a different domain (such as google.com). THis is because of the browser's Same Origin Policy.
This is a very good function file available on Matlab Central File Exchange.
This function file is totally vectorized and hence very quick. Plus, in comparison to the function being referred to in aioobe's answer, this function doesn't use the accumarray function, which is why this is even compatible with older versions of Matlab. Also, it works for cell arrays as well as numeric arrays.
SOLUTION : You can use this function in conjunction with the built in matlab function, "unique".
occurance_count = countmember(unique(M),M)
occurance_count will be a numeric array with the same size as that of unique(M) and the different values of occurance_count array will correspond to the count of corresponding values (same index) in unique(M).
You can always change a date on your computer, make a commit, then change the date back and push.
In postgres this works very nicely..Tell the server the time at which the time is saved, 'utc', and then ask it to convert to a specific timezone, in this case 'Brazil/East'
quiz_step_progresses.created_at at time zone 'utc' at time zone 'Brazil/East'
Get a complete list of timezones with the following select;
select * from pg_timezone_names;
See details here.

I faced the same problem, the following changes solved my problem.
$(document).ready(function() {
$('.datatable').dataTable( {
bSort: false,
aoColumns: [ { sWidth: "45%" }, { sWidth: "45%" }, { sWidth: "10%", bSearchable: false, bSortable: false } ],
"scrollY": "200px",
"scrollCollapse": true,
"info": true,
"paging": true
} );
} );
the aoColumns
array describes the width of each column and its sortable
properties.
Another thing to mention this error will also appear when you order by a column number that does not exist.
To change it from css you dont even need to set the child class
.parent > div:nth-child(1) { display:none; }
.parent:hover > div:nth-child(1) { display: block; }
Edit: See cambunctious's answer, which is basically what I now prefer because it only uses the changes in the stash, rather than comparing them to your current state. This makes the operation additive, with much less chance of undoing work done since the stash was created.
To do it interactively, you would first do
git diff stash^! -- path/to/relevant/file/in/stash.ext perhaps/another/file.ext > my.patch
...then open the patch file in a text editor, alter as required, then do
git apply < my.patch
cambunctious's answer bypasses the interactivity by piping one command directly to the other, which is fine if you know you want all changes from the stash. You can edit the stash^!
to be any commit range that has the cumulative changes you want (but check over the output of the diff first).
If applying the patch/diff fails, you can change the last command to git apply --reject
which makes all the changes it can, and leaves .rej
files where there are conflicts it can;r resolve. The .rej
files can then be applied using wiggle
, like so:
wiggle --replace path/to/relevant/file/in/stash.ext path/to/relevant/file/in/stash.ext.rej
This will either resolve the conflict, or give you conflict markers that you'd get from a merge.
Previous solution: There is an easy way to get changes from any branch, including stashes:
$ git checkout --patch stash@{0} path/to/file
You may omit the file spec if you want to patch in many parts. Or omit patch (but not the path) to get all changes to a single file. Replace 0
with the stash number from git stash list
, if you have more than one. Note that this is like diff
, and offers to apply all differences between the branches. To get changes from only a single commit/stash, have a look at git cherry-pick --no-commit
.
For Entity Framework and Linq to SQL we can achieve this by defining an extension method which modifies an Expression
passed to IQueryable<T>.Max(...)
method:
static class Extensions
{
public static TResult MaxOrDefault<T, TResult>(this IQueryable<T> source,
Expression<Func<T, TResult>> selector)
where TResult : struct
{
UnaryExpression castedBody = Expression.Convert(selector.Body, typeof(TResult?));
Expression<Func<T, TResult?>> lambda = Expression.Lambda<Func<T,TResult?>>(castedBody, selector.Parameters);
return source.Max(lambda) ?? default(TResult);
}
}
Usage:
int maxId = dbContextInstance.Employees.MaxOrDefault(employee => employee.Id);
// maxId is equal to 0 if there is no records in Employees table
The generated query is identical, it works just like a normal call to IQueryable<T>.Max(...)
method, but if there is no records it returns a default value of type T instead of throwing an exeption
Set font-size
in viewport-width-related units, e.g.:
table { font-size: 0.9vw; }
This will make font unreadable when page is too narrow, but sometimes this is acceptable.
I think you can use the nrows
parameter. From the docs:
nrows : int, default None
Number of rows of file to read. Useful for reading pieces of large files
which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):
In [1]: import pandas as pd
In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s
In [3]: len(z)
Out[3]: 20
In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s
This question is old and got many answers.
Now with Java 8 and Official Lambda that are unofficial closure projects, it revives the question.
The answer in Java context (via Lambdas and closures — what’s the difference?):
"A closure is a lambda expression paired with an environment that binds each of its free variables to a value. In Java, lambda expressions will be implemented by means of closures, so the two terms have come to be used interchangeably in the community."
As mentioned in the above answers, We can use JSON.parse()
to parse the strings to JSON
But before parsing, be sure to parse the correct data or else it might bring your whole application down
it is safe to use it like this
let parsedObj = {}
try {
parsedObj = JSON.parse(data);
} catch(e) {
console.log("Cannot parse because data is not is proper json format")
}
Say P7 is a Cell then you can use the following Syntex to check the value of the cell and assign appropriate value to another cell based on this following nested if:
=IF(P7=0,200,IF(P7=1,100,IF(P7=2,25,IF(P7=3,10,IF((P7=4),5,0)))))
I just encountered this same issue. Turned out the Project URL on the Web property sheet was malformed.
I had just removed a port number, forgot to delete the preceding colon and tried running with: http://localhost:/XYZ
Seems like lots of different issues result in this error message.
I swear to God.. the solution to this utterly basic problem eluded me for YEARS. It's SO simple.. but there is so much vague / bad information out there; hopefully I can save someone from some of the bottomless rabbit holes that I ended up in...
So then, lets's get a "string" from "the user" via "the console", via stdin
, shall we?
[NSString.alloc initWithData:
[NSFileHandle.fileHandleWithStandardInput availableData]
encoding:NSUTF8StringEncoding];
if you want it WITHOUT the trailing newline, just add...
[ ... stringByTrimmingCharactersInSet:
NSCharacterSet.newlineCharacterSet];
Ta Da!
? ??e?
You can use re.escape():
re.escape(string) Return string with all non-alphanumerics backslashed; this is useful if you want to match an arbitrary literal string that may have regular expression metacharacters in it.
>>> import re
>>> re.escape('^a.*$')
'\\^a\\.\\*\\$'
If you are using a Python version < 3.7, this will escape non-alphanumerics that are not part of regular expression syntax as well.
If you are using a Python version < 3.7 but >= 3.3, this will escape non-alphanumerics that are not part of regular expression syntax, except for specifically underscore (_
).
The first code is an example of Javascript code, which is similar, however not JSON. JSON would not have 1) comments and 2) the var
keyword
You don't have any comments in your JSON, but you should remove the var
and start like this:
orders: {
The [{}]
notation means "object in an array" and is not what you need everywhere. It is not an error, but it's too complicated for some purposes. AssociatedDrug should work well as an object:
"associatedDrug": {
"name":"asprin",
"dose":"",
"strength":"500 mg"
}
Also, the empty object labs should be filled with something.
Other than that, your code is okay. You can either paste it into javascript, or use the JSON.parse()
method, or any other parsing method (please don't use eval)
Update 2 answered:
obj.problems[0].Diabetes[0].medications[0].medicationsClasses[0].className[0].associatedDrug[0].name
returns 'aspirin'. It is however better suited for foreaches everywhere
Seems like you forgot the ["value"] or ->value
:
echo $data[0]->weather->weatherIconUrl[0]->value;
None of these solutions worked. only changing the workspace worked for me.
The traditional way to flag a method so that it will appear in Interface Builder, and you can drag a connection to it, has been to make the method return type IBAction. However, if you make your method void, instead (IBAction is #define'd to be void), and provide an (id) argument, the method is still visible. This provides extra flexibility, al
All 3 of these are visible from Interface Builder:
-(void) someMethod1:(id) sender;
-(IBAction) someMethod2;
-(IBAction) someMethod3:(id) sender;
See Apple's Interface Builder User Guide for details, particularly the section entitled Xcode Integration.
You can use the the ResultSetMetaData (http://java.sun.com/javase/6/docs/api/java/sql/ResultSetMetaData.html) object for that, like this:
ResultSet rs = stmt.executeQuery("SELECT * FROM table");
ResultSetMetaData rsmd = rs.getMetaData();
String firstColumnName = rsmd.getColumnName(1);
Even though it is a runnable jar, you can still run it from a console -- open a terminal window, navigate to the directory containing the jar, and enter "java -jar yourJar.jar". It will run in that terminal window, and sysout and syserr output will appear there, including stack traces from uncaught exceptions. Be sure to have your debug set to true when you compile. And good luck.
Just thought of something else -- if you're on Win7, it often has permission problems with user applications writing files to specific directories. Make sure the directory to which you are writing your output file is one for which you have permissions.
In a future project, if it's big enough, you can use one of the standard logging facilities for 'debug' output; then it will be easy(ier) to redirect it to a file instead of depending on having a console. But for a smaller job like this, this should be fine.
This jQuery plugin gives you a pre-made way of selection/caret manipulation.
I second Dipaks' answer, but often just the text-indent is enough as you may/maynot be positioning the ul for better layout control.
ul li{
text-indent: -1em;
}

System.out.println("Enter your email: ");

System.out.println(" Welcome User!!");

System.out.println(" Re-enter your email: ");

System.out.println(" Re-enter your password: ");
}
} while (!email_valid || !password_valid);
input.close();
}
}
IEquatable<T>
can be a much easier way to do this with modern frameworks.
You get a nice simple bool Equals(T other)
function and there's no messing around with casting or creating a separate class.
public class Person : IEquatable<Person>
{
public Person(string name, string hometown)
{
this.Name = name;
this.Hometown = hometown;
}
public string Name { get; set; }
public string Hometown { get; set; }
// can't get much simpler than this!
public bool Equals(Person other)
{
return this.Name == other.Name && this.Hometown == other.Hometown;
}
public override int GetHashCode()
{
return Name.GetHashCode(); // see other links for hashcode guidance
}
}
Note you DO have to implement GetHashCode
if using this in a dictionary or with something like Distinct
.
PS. I don't think any custom Equals methods work with entity framework directly on the database side (I think you know this because you do AsEnumerable) but this is a much simpler method to do a simple Equals for the general case.
If things don't seem to be working (such as duplicate key errors when doing ToDictionary) put a breakpoint inside Equals to make sure it's being hit and make sure you have GetHashCode
defined (with override keyword).
Faced with the same issue when trying to check if a button is disabled. I've tried a variety of approaches, such as btn.disabled
, .is(':disabled')
, .attr('disabled')
, .prop('disabled')
. But no one works for me.
Some, for example .disabled
or .is(':disabled')
returned undefined
and other like .attr('disabled')
returned the wrong result - false
when the button was actually disabled.
But only one technique works for me: .is('[disabled]')
(with square brackets).
So to determine if a button is disabled try this:
$("#myButton").is('[disabled]');
I think it's worth showing the difference between the various options mentioned - often a picture is worth a thousand words.

To summarize:
vars()
and __dict__
only return instance-local properties;dir()
returns everything, but only as a list of string member names; dynamic properties are not called;inspect.getmembers()
returns everything, as a list of tuples (name, value)
; it actually runs dynamic properties, and accepts an optional predicate
argument that can filter out members by value.So my common-sense approach is typically to use dir()
on the command line, and getmembers()
in programs, unless specific performance considerations apply.
Note that, to keep things cleaner, I did not include __slots__
- if present, it was explicitly put there to be queried, and should be used directly. I also did not cover metaclasses, which can get a bit hairy (most people will never use them anyway).
If you do android native code development using NDK, give Visual Studio a try. (Not a typo!!!) Check out: http://ian-ni-lewis.blogspot.com/2011/01/its-like-coming-home-again.html
Can you be a bit more specific about what you're trying to do and how you're trying to do it?
If you're attempting to invoke the program using the <exec>
task you might do the following:
<exec executable="name-of-executable">
<arg value="arg0"/>
<arg value="arg1"/>
</exec>
Partial Functional Dependency occurs only in relation with composite keys. Partial functional dependency occurs when one or more non key attribute are depending on a part of the primary key.
Example:
Table: Stud_id, Course_id, Stud_name, Course_Name
Where: Primary Key = Stud_id + Course_id
Then: To determine name of student we use only Stud_id, which is part of primary key.
{Stud_id} -> {Stud_Name}
Hence,Stud_name is partially dependent on Stud_id. This is called partial dependency.
Use mutple backgorund on the element, and use a linear-gradient as your color overlay by declaring both start and end color-stops as the same value.
Note that layers in a multi-background declaration are read much like they are rendered, top-to-bottom, so put your overlay first, then your bg image:
#header {
background:
linear-gradient(to bottom, rgba(100, 100, 0, 0.5), rgba(100, 100, 0, 0.5)) cover,
url(../img/bg.jpg) 0 0 no-repeat fixed;
height: 100%;
overflow: hidden;
color: #FFFFFF
}
I think you can use db.collection.distinct(fields,query)
You will be able to get the distinct values in your case for NetworkID.
It should be something like this :
Db.collection.distinct('NetworkID')
Consider using the decorator pattern http://en.wikipedia.org/wiki/Decorator_pattern
You can change the decorator at runtime with one that has different properties when an event occurs.
Following official Heroku article:
Initialize GIT
$ cd myapp
$ git init
$ git add .
$ git commit -m "my first commit"
Then create (initialize) heroku app with:
$ heroku create YourAppName
Lastly add git remote:
$ heroku git:remote -a YourAppName
Now you can safely deploy your app with:
$ git push heroku master
You should wait for some time and see if you don't get any error/interrupt on console while deploying. For details look at heroku article.
Alternatively, you can use evals
from my pander
package to capture output and all warnings, errors and other messages along with the raw results:
> pander::evals("5+5")
[[1]]
$src
[1] "5 + 5"
$result
[1] 10
$output
[1] "[1] 10"
$type
[1] "numeric"
$msg
$msg$messages
NULL
$msg$warnings
NULL
$msg$errors
NULL
$stdout
NULL
attr(,"class")
[1] "evals"
just use inner join because group by won't work with multiple columns saying not contained in either an aggregate function.
SELECT a.*
FROM yourtable a
INNER JOIN
(SELECT yourcolumn,
MIN(id) as id
FROM yourtable
GROUP BY yourcolumn
) AS b
ON a.yourcolumn= b.yourcolumn
AND a.id = b.id;
Another way based on amadan:
SELECT * FROM [Purchasing].[Vendor] WHERE

This is an article that I always refer to when working with sockets..
It will show you how to reliably use 'select()' and contains some other useful links at the bottom for further info on sockets.
Like the other answer says, in the left hand side select Products and add product. Then select Facbook Login.
I then added http://localhost:3000/ to the field 'Valid OAuth redirect URIs', and then everything worked.
REST(REpresentation State Transfer) is an architecture using which WebServices are created.
and
RESTful is way of writing services using the REST architectures. RESTful services exposes the resources to identify the targets to interact with clients.
If the table is InnoDB, see http://dev.mysql.com/doc/refman/5.1/en/innodb-consistent-read.html -- it uses consistent-read (no-locking mode) for SELECTs "that do not specify FOR UPDATE or LOCK IN SHARE MODE if the innodb_locks_unsafe_for_binlog option is set and the isolation level of the transaction is not set to SERIALIZABLE. Thus, no locks are set on rows read from the selected table".
Using data.table
:
# convert to data.table
setDT(df)
# order, group, filter
df[order(stopSequence)][, .SD[c(1, .N)], by = id]
id stopId stopSequence
1: 1 a 1
2: 1 c 3
3: 2 b 1
4: 2 c 4
5: 3 b 1
6: 3 a 3
Im not a java developer but was using a java app to test a RESTful API. In order for me to fix the error I had to install the intermediate certificates in the webserver in order to make the error go away. I was using lighttpd, the original certificate was installed on an IIS server. Hope it helps. These were the certificates I had missing on the server.
There is actually a way to fix that. First you delete the auto_incremented primary key column, and then you add it again, like this:
ALTER TABLE table_name DROP column_name;
ALTER TABLE table_name ADD column_name int not null auto_increment primary key first;
Yes, all you need to do is call finish() in any Activity you would like to close.
require 'date'
current_time = DateTime.now
current_time.strftime "%d/%m/%Y %H:%M"
# => "14/09/2011 17:02"
current_time.next_month.strftime "%d/%m/%Y %H:%M"
# => "14/10/2011 17:02"
set height: 100%;
and overflow:auto;
for div inside .cell
I found this easier to understand:
List<string> names = new List<string> { "One", "Two", "Three", "Four", "Five" };
for (int i = 0; i < names.Count; i++)
{
Console.WriteLine(names[i]);
}
The one worked with me is kind of a modified version from Saleh's answer elsewhere on this page.

The recommended way is to let str.format
handle the casting (docs). Methods with %s
substitution may be deprecated eventually (see PEP3101).
>>> answer = True
>>> myvar = "the answer is {}".format(answer)
>>> print(myvar)
the answer is True
In Python 3.6+ you may use literal string interpolation:
>>> print(f"the answer is {answer}")
the answer is True
Try this:
a[id*='Some:Same'][id$='name']
This will get you all a
elements with id containing
Some:Same
and have the id ending in
name
.prop('disabled')
will return a Boolean:
var isDisabled = $('textbox').prop('disabled');
Here's the fiddle: http://jsfiddle.net/unhjM/
http://en.wikipedia.org/wiki/Representational_State_Transfer
The basic idea is that instead of having an ongoing connection to the server, you make a request, get some data, show that to a user, but maybe not all of it, and then when the user does something which calls for more data, or to pass some up to the server, the client initiates a change to a new state.

http://docs.oracle.com/javase/tutorial/java/package/namingpkgs.html
Companies use their reversed Internet domain name to begin their package names—for example, com.example.mypackage for a package named mypackage created by a programmer at example.com.
Name collisions that occur within a single company need to be handled by convention within that company, perhaps by including the region or the project name after the company name (for example, com.example.region.mypackage).
If you have a company domain www.example.com
Then you should use:
com.example.region.projectname
If you own a domain name like example.co.uk than it should be:
uk.co.example.region.projectname
If you do not own a domain, you should then use your email address:
for [email protected] it should be:
com.example.name.region.projectname

The criterion to satisfy for providing the new shape is that 'The new shape should be compatible with the original shape'
numpy allow us to give one of new shape parameter as -1 (eg: (2,-1) or (-1,3) but not (-1, -1)). It simply means that it is an unknown dimension and we want numpy to figure it out. And numpy will figure this by looking at the 'length of the array and remaining dimensions' and making sure it satisfies the above mentioned criteria
Now see the example.
z = np.array([[1, 2, 3, 4],
[5, 6, 7, 8],
[9, 10, 11, 12]])
z.shape
(3, 4)
Now trying to reshape with (-1) . Result new shape is (12,) and is compatible with original shape (3,4)
z.reshape(-1)
array([ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12])
Now trying to reshape with (-1, 1) . We have provided column as 1 but rows as unknown . So we get result new shape as (12, 1).again compatible with original shape(3,4)
z.reshape(-1,1)
array([[ 1],
[ 2],
[ 3],
[ 4],
[ 5],
[ 6],
[ 7],
[ 8],
[ 9],
[10],
[11],
[12]])
The above is consistent with numpy
advice/error message, to use reshape(-1,1)
for a single feature; i.e. single column
Reshape your data using
array.reshape(-1, 1)
if your data has a single feature
New shape as (-1, 2). row unknown, column 2. we get result new shape as (6, 2)
z.reshape(-1, 2)
array([[ 1, 2],
[ 3, 4],
[ 5, 6],
[ 7, 8],
[ 9, 10],
[11, 12]])
Now trying to keep column as unknown. New shape as (1,-1). i.e, row is 1, column unknown. we get result new shape as (1, 12)
z.reshape(1,-1)
array([[ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]])
The above is consistent with numpy
advice/error message, to use reshape(1,-1)
for a single sample; i.e. single row
Reshape your data using
array.reshape(1, -1)
if it contains a single sample
New shape (2, -1). Row 2, column unknown. we get result new shape as (2,6)
z.reshape(2, -1)
array([[ 1, 2, 3, 4, 5, 6],
[ 7, 8, 9, 10, 11, 12]])
New shape as (3, -1). Row 3, column unknown. we get result new shape as (3,4)
z.reshape(3, -1)
array([[ 1, 2, 3, 4],
[ 5, 6, 7, 8],
[ 9, 10, 11, 12]])
And finally, if we try to provide both dimension as unknown i.e new shape as (-1,-1). It will throw an error
z.reshape(-1, -1)
ValueError: can only specify one unknown dimension

Unfortunately for all the answers given by other folks, you can't DELETE
and SELECT
from a given table in the same query.
DELETE FROM mytable WHERE id NOT IN (SELECT MAX(id) FROM mytable);
ERROR 1093 (HY000): You can't specify target table 'mytable' for update
in FROM clause
Nor can MySQL support LIMIT
in a subquery. These are limitations of MySQL.
DELETE FROM mytable WHERE id NOT IN
(SELECT id FROM mytable ORDER BY id DESC LIMIT 1);
ERROR 1235 (42000): This version of MySQL doesn't yet support
'LIMIT & IN/ALL/ANY/SOME subquery'
The best answer I can come up with is to do this in two stages:
SELECT id FROM mytable ORDER BY id DESC LIMIT n;
Collect the id's and make them into a comma-separated string:
DELETE FROM mytable WHERE id NOT IN ( ...comma-separated string... );
(Normally interpolating a comma-separate list into an SQL statement introduces some risk of SQL injection, but in this case the values are not coming from an untrusted source, they are known to be integer values from the database itself.)
note: Though this doesn't get the job done in a single query, sometimes a more simple, get-it-done solution is the most effective.
If both Column are numeric Then Use This code
Just Cast Column As Varchar(Size)
Example:
Select (Cast(Col1 as Varchar(20)) + '-' + Cast(Col2 as Varchar(20))) As Col3 from Table
I ran into a problem in the docker node:current-slim (running npm 7.0.9) where npm install
appeared to ignore --production
, --only=prod
and --only=production
. I found two work-arounds:
RUN npm ci --only=production
) which requires an up-to-date package-lock.jsonnpm install
, brutally edit the package.json with:RUN node -e 'const fs = require("fs"); const pkg = JSON.parse(fs.readFileSync("./package.json", "utf-8")); delete pkg.devDependencies; fs.writeFileSync("./package.json", JSON.stringify(pkg), "utf-8");'
This won't edit your working package.json, just the one copied to the docker container. Of course, this shouldn't be necessary, but if it is (as it was for me), there's your hack.
An alternative option to the command line for deleting remote branches is the GitHub branches page.
See for example: https://github.com/angular/angular.js/branches
Found in the Code
-> Branches
page of a GitHub repository.
I generally prefer command line myself but this GitHub page shows you lots more information about the branches, such as last updated date and user, and number of commits ahead and behind. It is useful when dealing with a large number of branches.
Sorry to reopen an old question, but since it was edited recently saying that the "issue" still remains in Java 11, I felt like I wanted to point out this:
answerList
.stream()
.collect(Collectors.toMap(Answer::getId, Answer::getAnswer));
gives you the null pointer exception because the map does not allow null as a value.
This makes sense because if you look in a map for the key k
and it is not present, then the returned value is already null
(see javadoc). So if you were able to put in k
the value null
, the map would look like it's behaving oddly.
As someone said in the comments, it's pretty easy to solve this by using filtering:
answerList
.stream()
.filter(a -> a.getAnswer() != null)
.collect(Collectors.toMap(Answer::getId, Answer::getAnswer));
in this way no null
values will be inserted in the map, and STILL you will get null
as the "value" when looking for an id that does not have an answer in the map.
I hope this makes sense to everyone.
According to the documentation:
$validator = Validator::make($request->all(), [
'file' => 'max:500000',
]);
The value is in kilobytes. I.e. max:10240
= max 10 MB.
You can't commit empty folders in git. If you want it to show up, you need to put something in it, even just an empty file.
For example, add an empty file called .gitkeep
to the folder you want to keep, then in your .gitignore
file write:
# exclude everything
somefolder/*
# exception to the rule
!somefolder/.gitkeep
Commit your .gitignore
and .gitkeep
files and this should resolve your issue.
I don't know, if it's only with me but for me og:image

Definitely avoid using eval
to do something like this, or you will open yourself to XSS (Cross-Site Scripting) vulnerabilities.
For example, if you were to use the eval
solutions proposed here, a nefarious user could send a link to their victim that looked like this:
http://yoursite.com/foo.html?func=function(){alert('Im%20In%20Teh%20Codez');}
And their javascript, not yours, would get executed. This code could do something far worse than just pop up an alert of course; it could steal cookies, send requests to your application, etc.
So, make sure you never eval
untrusted code that comes in from user input (and anything on the query string id considered user input). You could take user input as a key that will point to your function, but make sure that you don't execute anything if the string given doesn't match a key in your object. For example:
// set up the possible functions:
var myFuncs = {
func1: function () { alert('Function 1'); },
func2: function () { alert('Function 2'); },
func3: function () { alert('Function 3'); },
func4: function () { alert('Function 4'); },
func5: function () { alert('Function 5'); }
};
// execute the one specified in the 'funcToRun' variable:
myFuncs[funcToRun]();
This will fail if the funcToRun
variable doesn't point to anything in the myFuncs
object, but it won't execute any code.
Note: Due to changes made to jQuery 1.9 and jQuery UI, this answer is no longer the correct one. Please see @stankovski's answer below.
You need to find the tab's index first (which is just its position in a list) and then specifically select the tab using jQuery UI's provided select event (tabs->select).
var index = $('#tabs ul').index($('#tabId'));
$('#tabs ul').tabs('select', index);
Update: BTW - I do realize that this is (ultimately) still selecting by index. But, it doesn't require that you know the specific position of the tabs (particularly when they are dynamically generated as asked in the question).
You can write that for example:
private Date TruncarFecha(Date fechaParametro) throws ParseException {
String fecha="";
DateFormat outputFormatter = new SimpleDateFormat("MM/dd/yyyy");
fecha =outputFormatter.format(fechaParametro);
return outputFormatter.parse(fecha);
}
you pretty much answered your own question - hashset doesn't allow duplicate values. it would be trivial to build a hashset using a backing hashmap (and just a check to see if the value already exists). i guess the various java implementations either do that, or implement some custom code to do it more efficiently.
This is deletes the table table_name

Use gradle dependencies to get the Gson in your project. Your application build.gradle should look like this-

If you want to open command prompt inside your eclipse, this can be a useful approach to link cmd with eclipse.
You can follow this link to get the steps in detail with screenshots. How to use cmd prompt inside Eclipse ?
I'm quoting the steps here:
Step 1: Setup a new External Configuration Tool
In the Eclipse tool go to Run -> External Tools -> External Tools Configurations option.
Step 2: Click New Launch Configuration option in Create, manage and run configuration screen
Step 3: New Configuration screen for configuring the command prompt
Step 4: Provide configuration details of the Command Prompt in the Main tab
Name: Give any name to your configuration (Here it is Command_Prompt)
Location: Location of the CMD.exe in your Windows
Working Directory: Any directory where you want to point the Command prompt
Step 5: Tick the check box Allocate console This will ensure the eclipse console is being used as the command prompt for any input or output.
Step 6: Click Run and you are there!! You will land up in the C: directory as a working directory
I am providing the modern answer. The Timestamp
class is a hack on top of the already poorly designed java.util.Date
class and is long outdated. I am assuming, though, that you are getting a Timestamp
from a legacy API that you cannot afford to upgrade to java.time just now. When you do that, convert it to a modern Instant
and do further processing from there.
DateTimeFormatter formatter = DateTimeFormatter.ofLocalizedDateTime(FormatStyle.MEDIUM)
.withLocale(Locale.GERMAN);
Timestamp oldfashionedTimestamp = new Timestamp(1_567_890_123_456L);
ZonedDateTime dateTime = oldfashionedTimestamp.toInstant()
.atZone(ZoneId.systemDefault());
String desiredFormat = dateTime.format(formatter);
System.out.println(desiredFormat);
Output in my time zone:
07.09.2019 23:02:03
Pick how long or short of a format you want by specifying FormatStyle.SHORT
, .MEDIUM
, .LONG
or .FULL
. Pick your own locale where I put Locale.GERMAN
. And pick your desired time zone, for example ZoneId.of("Europe/Oslo")
. A Timestamp
is a point in time without time zone, so we need a time zone to be able to convert it into year, month, day, hour, minute, etc. If your Timestamp
comes from a database value of type timestamp
without time zone (generally not recommended, but unfortunately often seen), ZoneId.systemDefault()
is likely to give you the correct result. Another and slightly simpler option in this case is instead to convert to a LocalDateTime
using oldfashionedTimestamp.toLocalDateTime()
and then format the LocalDateTime
in the same way as I did with the ZonedDateTime
.
For rails 3.2.3 and latest version of rails you can start server by:
First install all gem with command: bundle install
or bundle
.
Then Configure your database to the database.yml
.
Create new database: rake db:create
Then start rails server.
rails server
orrails s
It is also good idea to use supervisord or runit[1] for service management.
You need to load a package (like magrittr
or dplyr
) that defines the function first, then it should work.
install.packages("magrittr") # package installations are only needed the first time you use it
install.packages("dplyr") # alternative installation of the %>%
library(magrittr) # needs to be run every time you start R and want to use %>%
library(dplyr) # alternatively, this also loads %>%
The pipe operator %>%
was introduced to "decrease development time and to improve readability and maintainability of code."
But everybody has to decide for himself if it really fits his workflow and makes things easier.
For more information on magrittr
, click here.
Not using the pipe %>%
, this code would return the same as your code:
words <- colnames(as.matrix(dtm))
words <- words[nchar(words) < 20]
words
EDIT: (I am extending my answer due to a very useful comment that was made by @Molx)
Despite being from
magrittr
, the pipe operator is more commonly used with the packagedplyr
(which requires and loadsmagrittr
), so whenever you see someone using%>%
make sure you shouldn't loaddplyr
instead.
Instead of using a bat file, you can simply create a Scheduled Task. Most of the time you define just one action. In this case, create two actions with the NET
command. The first one to stop the service, the second one to start the service. Give them a STOP
and START
argument, followed by the service name.
In this example we restart the Printer Spooler service.
NET STOP "Print Spooler"
NET START "Print Spooler"
Note: unfortunately NET RESTART <service name>
does not exist.
select d.dname
,count(e.empno) as count
from dept d
left outer join emp e
on e.deptno=d.deptno
group by d.dname;
Your scanf("%s", s);
is commented out. That means s is uninitialized, so when this line ln = strlen(s);
executes, you get a seg fault.
It always helps to initialize a pointer to NULL, and then test for null before using the pointer.

If you're getting this error, you're probably trying to write to wwwroot
. By default this is not allowed, for good reason.
Instead, consider storing your files somewhere besides wwwroot
. If you just need to serve the files, store them in a folder outside of inetpub
and use a virtual directory to make them visible to IIS.
Original answer:
For those running IIS on Windows Server:
By default, the IIS user does not have write permissions for the wwwroot
folder. This can be solved by granting full permissions to the IIS_IUSRS
user for wwwroot
.
C:/inetpub/
IIS_IUSRS ([server name]\IIS_IUSRS)

Another way to do this without the overhead of an Ajax call or WebService handler is to load a special ASPX page after a given amount of time (i.e., prior to the session state time-out, which is typically 20 minutes):
// Client-side JavaScript
function pingServer() {
// Force the loading of a keep-alive ASPX page
var img = new Image(1, 1);
img.src = '/KeepAlive.aspx';
}
The KeepAlive.aspx
page is simply an empty page which does nothing but touch/refresh the Session
state:
// KeepAlive.aspx.cs
public partial class KeepSessionAlive: System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
// Refresh the current user session
Session["refreshTime"] = DateTime.UtcNow;
}
}
This works by creating an img
(image) element and forcing the browser to load its contents from the KeepAlive.aspx
page. Loading that page causes the server to touch (update) the Session
object, extending the session's expiration sliding time window (typically by another 20 minutes). The actual web page contents are discarded by the browser.
An alternative, and perhaps cleaner, way to do this is to create a new iframe
element and load the KeepAlive.aspx
page into it. The iframe
element is hidden, such as by making it a child element of a hidden div
element somewhere on the page.
Activity on the page itself can be detected by intercepting mouse and keyboard actions for the entire page body:
// Called when activity is detected
function activityDetected(evt) {
...
}
// Watch for mouse or keyboard activity
function watchForActivity() {
var opts = { passive: true };
document.body.addEventListener('mousemove', activityDetected, opts);
document.body.addEventListener('keydown', activityDetected, opts);
}
I cannot take credit for this idea; see: https://www.codeproject.com/Articles/227382/Alert-Session-Time-out-in-ASP-Net.
This is a problem of M2E for Eclipse M2E plugin execution not covered.
To solve this problem, all you got to do is to map the lifecycle it doesn't recognize and instruct M2E to execute it.
You should add this after your plugins
, inside the build
. This will remove the error and make M2E recognize the goal copy-depencies
of maven-dependency-plugin
and make the POM work as expected, copying dependencies to folder every time Eclipse build it. If you just want to ignore the error, then you change <execute />
for <ignore />
. No need for enclosing your maven-dependency-plugin
into pluginManagement
, as suggested before.

Jai is correct that you should use INSERT ... ON DUPLICATE KEY UPDATE
.
Note that you do not need to include datenum in the update clause since it's the unique key, so it should not change. You do need to include all of the other columns from your table. You can use the VALUES()
function to make sure the proper values are used when updating the other columns.
Here is your update re-written using the proper INSERT ... ON DUPLICATE KEY UPDATE
syntax for MySQL:
INSERT INTO AggregatedData (datenum,Timestamp)
VALUES ("734152.979166667","2010-01-14 23:30:00.000")
ON DUPLICATE KEY UPDATE
Timestamp=VALUES(Timestamp)
Instead of using the body you could create a curtain with z-index
of 100 (to pick a number) and give the inside element a higher z-index
while all other elements have a lower z-index than the curtain.
See working example here: http://jsfiddle.net/Flandre/6JvFk/
jQuery:
$('#curtain').on("click", function(e) {
$(this).hide();
alert("clicked ouside of elements that stand out");
});
CSS:
.aboveCurtain
{
z-index: 200; /* has to have a higher index than the curtain */
position: relative;
background-color: pink;
}
#curtain
{
position: fixed;
top: 0px;
left: 0px;
height: 100%;
background-color: black;
width: 100%;
z-index:100;

Curl should now work with that URL correctly.
First is latitude, second longitude. Different than many constructors in mapbox.

and the first number in your longitude coordinate is between -180
and 180
.Using for:
for each in "${alpha[@]}"
do
echo "$each"
done
Using history; note this will fail if your values contain !
:
history -p "${alpha[@]}"
Using basename; note this will fail if your values contain /
:
basename -a "${alpha[@]}"
Using shuf; note that results might not come out in order:
shuf -e "${alpha[@]}"
If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:
The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.
In 2019 you can use querySelector for that.
It's supported by most browsers (https://caniuse.com/#search=querySelector)
document.querySelector('body').appendChild(i);
This fixes the problem on both Safari and Chrome
if(navigator.userAgent.toLowerCase().indexOf("chrome") >= 0 || navigator.userAgent.toLowerCase().indexOf("safari") >= 0){
window.setInterval(function(){
$('input:-webkit-autofill').each(function(){
var clone = $(this).clone(true, true);
$(this).after(clone).remove();
});
}, 20);
}
What moves origin/HEAD "organically"?
git clone
sets it once to the spot where HEAD is on origin
git clone
What does HEAD on origin represent?
git clone
uses it in such a wayWhat sets origin/HEAD?
git clone
fetches and sets itgit fetch
updates it like any other reference, but it doesn’tgit remote set-head origin -a
fetches and sets it
Trivia
origin/HEAD
can also be set to any other value without contacting the remote: git remote set-head origin <branch>
I found that contentSize
doesn't really reflect the actual size of the text, so when trying to scroll to the bottom, it will be a little bit off. The best way to determine the actual content size is actually to use the NSLayoutManager
's usedRectForTextContainer:
method:
UITextView *textView;
CGSize textSize = [textView.layoutManager usedRectForTextContainer:textView.textContainer].size;
To determine how much text actually is shown in the UITextView
, you can calculate it by subtracting the text container insets from the frame height.
UITextView *textView;
UIEdgeInsets textInsets = textView.textContainerInset;
CGFloat textViewHeight = textView.frame.size.height - textInsets.top - textInsets.bottom;
Then it becomes easy to scroll:
// if you want scroll animation, use contentOffset
UITextView *textView;
textView.contentOffset = CGPointMake(textView.contentOffset.x, textSize - textViewHeight);
// if you don't want scroll animation
CGRect scrollBounds = textView.bounds;
scrollBounds.origin = CGPointMake(textView.contentOffset.x, textSize - textViewHeight);
textView.bounds = scrollBounds;
Some numbers for reference on what the different sizes represent for an empty UITextView
.
textView.frame.size = (width=246, height=50)
textSize = (width=10, height=16.701999999999998)
textView.contentSize = (width=246, height=33)
textView.textContainerInset = (top=8, left=0, bottom=8, right=0)
Got the most easiest hack for this problem-use this syntax in your HTML-input-tag
<input type="text" id="my_element_id" placeholder="select a date" name="my_element_name" onfocus="(this.type='date')" />
</div>
