Combining approaches of @Denis and @Mark:
from collections import namedtuple
import inspect
class Node(namedtuple('Node', 'left right val')):
__slots__ = ()
def __new__(cls, *args, **kwargs):
args_list = inspect.getargspec(super(Node, cls).__new__).args[len(args)+1:]
params = {key: kwargs.get(key) for key in args_list + kwargs.keys()}
return super(Node, cls).__new__(cls, *args, **params)
That should support creating the tuple with positional arguments and also with mixed cases. Test cases:
>>> print Node()
Node(left=None, right=None, val=None)
>>> print Node(1,2,3)
Node(left=1, right=2, val=3)
>>> print Node(1, right=2)
Node(left=1, right=2, val=None)
>>> print Node(1, right=2, val=100)
Node(left=1, right=2, val=100)
>>> print Node(left=1, right=2, val=100)
Node(left=1, right=2, val=100)
>>> print Node(left=1, right=2)
Node(left=1, right=2, val=None)
but also support TypeError:
>>> Node(1, left=2)
TypeError: __new__() got multiple values for keyword argument 'left'
Use the properties-maven-plugin to write specific pom properties
to a file at compile time, and then read that file at run time.
In your pom.xml:
<properties>
<name>${project.name}</name>
<version>${project.version}</version>
<foo>bar</foo>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>properties-maven-plugin</artifactId>
<version>1.0.0</version>
<executions>
<execution>
<phase>generate-resources</phase>
<goals>
<goal>write-project-properties</goal>
</goals>
<configuration>
<outputFile>${project.build.outputDirectory}/my.properties</outputFile>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
And then in .java:
java.io.InputStream is = this.getClass().getResourceAsStream("my.properties");
java.util.Properties p = new Properties();
p.load(is);
String name = p.getProperty("name");
String version = p.getProperty("version");
String foo = p.getProperty("foo");
Using jQuery function
var valFileDownloadPath = 'http//:'+'your url';

There is a useful guide to the various methods of merging, joining and concatenating online.
For example, as you have no clashing columns you can merge
and use the indices as they have the same number of rows:
In [6]:
df_a.merge(df_b, left_index=True, right_index=True)
Out[6]:
AAseq Biorep Techrep Treatment mz AAseq1 Biorep1 Techrep1 \

Password Protected Zip File
if you want to compress files with password you can take a look at this library that can zip files with password easily:
Zip:
ZipArchive zipArchive = new ZipArchive();
zipArchive.zip(targetPath,destinationPath,password);
Unzip:
ZipArchive zipArchive = new ZipArchive();
zipArchive.unzip(targetPath,destinationPath,password);
Rar:
RarArchive rarArchive = new RarArchive();
rarArchive.extractArchive(file archive, file destination);
The documentation of this library is good enough, I just added a few examples from there. It's totally free and wrote specially for android.
I am getting similar errors recently because recent JDKs (and browsers, and the Linux TLS stack, etc.) refuse to communicate with some servers in my customer's corporate network. The reason of this is that some servers in this network still have SHA-1 certificates.
Please see: https://www.entrust.com/understanding-sha-1-vulnerabilities-ssl-longer-secure/ https://blog.qualys.com/ssllabs/2014/09/09/sha1-deprecation-what-you-need-to-know
If this would be your current case (recent JDK vs deprecated certificate encription) then your best move is to update your network to the proper encription technology.
In case that you should provide a temporal solution for that, please see another answers to have an idea about how to make your JDK trust or distrust certain encription algorithms:
How to force java server to accept only tls 1.2 and reject tls 1.0 and tls 1.1 connections
Anyway I insist that, in case that I have guessed properly your problem, this is not a good solution to the problem and that your network admin should consider removing these deprecated certificates and get a new one.
You could try using the -Clear
parameter
Example:-Clear Attribute1LDAPDisplayName, Attribute2LDAPDisplayName
Perhaps not the best options but just another way is to read the Windows Registry in the host machine, on elevated PowerShell prompt you can do something like this:
#Get SQL instance's Port number using Windows Registry:
$instName = (Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server').InstalledInstances[0]
$tcpPort = (Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\$instName\MSSQLServer\SuperSocketNetLib\Tcp").TcpPort
Write-Host The SQL Instance: `"$instName`" is listening on `"$tcpPort`" "TcpPort."
Ensure to run this PowerShell script in the Host Server (that hosts your SQL instance / SQL Server installation), which means you have to first RDP into the SQL Server/Box/VM, then run this code.

I think that if your "item_manuf_id" is the primary key of the DataTable you could use the Find method ...
string s = "stringValue";
DataRow foundRow = dtPs.Rows.Find(s);
if(foundRow != null) {
//You have it ...
}
If you're accessing this via a View then try sp_recompile
or refreshing views.
sp_recompile
:
Causes stored procedures, triggers, and user-defined functions to be recompiled the next time that they are run. It does this by dropping the existing plan from the procedure cache forcing a new plan to be created the next time that the procedure or trigger is run. In a SQL Server Profiler collection, the event SP:CacheInsert is logged instead of the event SP:Recompile.
Arguments
[ @objname= ] 'object'
The qualified or unqualified name of a stored procedure, trigger, table, view, or user-defined function in the current database. object is nvarchar(776), with no default. If object is the name of a stored procedure, trigger, or user-defined function, the stored procedure, trigger, or function will be recompiled the next time that it is run. If object is the name of a table or view, all the stored procedures, triggers, or user-defined functions that reference the table or view will be recompiled the next time that they are run.
Return Code Values
0 (success) or a nonzero number (failure)
Remarks
sp_recompile
looks for an object in the current database only.
The queries used by stored procedures, or triggers, and user-defined functions are optimized only when they are compiled. As indexes or other changes that affect statistics are made to the database, compiled stored procedures, triggers, and user-defined functions may lose efficiency. By recompiling stored procedures and triggers that act on a table, you can reoptimize the queries.
Here it fails at Array.apply(null, new Array(1000000))
and not the .map
call.
All functions arguments must fit on callstack(at least pointers of each argument), so in this they are too many arguments for the callstack.
You need to the understand what is call stack.
Stack is a LIFO data structure, which is like an array that only supports push and pop methods.
Let me explain how it works by a simple example:
function a(var1, var2) {
var3 = 3;
b(5, 6);
c(var1, var2);
}
function b(var5, var6) {
c(7, 8);
}
function c(var7, var8) {
}
When here function a
is called, it will call b
and c
. When b
and c
are called, the local variables of a
are not accessible there because of scoping roles of Javascript, but the Javascript engine must remember the local variables and arguments, so it will push them into the callstack. Let's say you are implementing a JavaScript engine with the Javascript language like Narcissus.
We implement the callStack as array:
var callStack = [];
Everytime a function called we push the local variables into the stack:
callStack.push(currentLocalVaraibles);
Once the function call is finished(like in a
, we have called b
, b
is finished executing and we must return to a
), we get back the local variables by poping the stack:
currentLocalVaraibles = callStack.pop();
So when in a
we want to call c
again, push the local variables in the stack. Now as you know, compilers to be efficient define some limits. Here when you are doing Array.apply(null, new Array(1000000))
, your currentLocalVariables
object will be huge because it will have 1000000
variables inside. Since .apply
will pass each of the given array element as an argument to the function. Once pushed to the call stack this will exceed the memory limit of call stack and it will throw that error.
Same error happens on infinite recursion(function a() { a() }
) as too many times, stuff has been pushed to the call stack.
Note that I'm not a compiler engineer and this is just a simplified representation of what's going on. It really is more complex than this. Generally what is pushed to callstack is called stack frame which contains the arguments, local variables and the function address.
One more case is that You only can collate with instanceof
- it returns true or false. With typeof
you can get type of provided something
Consider using getopt_long()
. It allows both short and long options in any combination.
#include <stdio.h>

static int verbose_flag;

main (int argc, char *argv[])

{"blip", no_argument, 0, 'b'},
{"slip", no_argument, 0, 's'},
{0, 0, 0, 0}
};
/* getopt_long stores the option index here. */
int option_index = 0;
int c = getopt_long (argc, argv, "bs",
long_options, &option_index);
/* Detect the end of the options. */
if (c == -1)
break;
switch (c)
{
case 0:
/* If this option set a flag, do nothing else now. */
if (long_options[option_index].flag != 0)
break;
printf ("option %s", long_options[option_index].name);
if (optarg)
printf (" with arg %s", optarg);
printf ("\n");
break;
case 'b':
puts ("option -b\n");
break;
case 's':
puts ("option -s\n");
break;
case '?':
/* getopt_long already printed an error message. */
break;
default:
abort ();
}
}
if (verbose_flag)
puts ("verbose flag is set");
/* Print any remaining command line arguments (not options). */
if (optind < argc)
{
printf ("non-option ARGV-elements: ");
while (optind < argc)
printf ("%s ", argv[optind++]);
putchar ('\n');
}
return 0;

I find a good way of achieving this at Remove browse button from input=file.
The rationale behind this solution is that it creates a transparent input=file control and creates an layer visible to the user below the file control. The z-index of the input=file will be higher than the layer.
With this, it appears that the layer is the file control itself. But actually when you clicks on it, the input=file is the one clicked and the dialog for choosing file will appear.
Delete bin and obj folders in all projects of that solution.
Seems like those folders were having old files generated by some older version of visual studio, which are not compatible with new version of visual studio.
My suggestion is to use a function. But rather than putting the if
in the function, which you might be tempted to do, do it like this:
if verbose:
def verboseprint(*args):
# Print each argument separately so caller doesn't need to
# stuff everything to be printed into a single string
for arg in args:
print arg,
print
else:
verboseprint = lambda *a: None # do-nothing function
(Yes, you can define a function in an if
statement, and it'll only get defined if the condition is true!)
If you're using Python 3, where print
is already a function (or if you're willing to use print
as a function in 2.x using from __future__ import print_function
) it's even simpler:
verboseprint = print if verbose else lambda *a, **k: None
This way, the function is defined as a do-nothing if verbose mode is off (using a lambda), instead of constantly testing the verbose
flag.
If the user could change the verbosity mode during the run of your program, this would be the wrong approach (you'd need the if
in the function), but since you're setting it with a command-line flag, you only need to make the decision once.
You then use e.g. verboseprint("look at all my verbosity!", object(), 3)
whenever you want to print a "verbose" message.
Necropost, but helpful: I came across this problem with an RA request failed since the files "already existed on the server" but wouldn't sync with my repository. I went to the source on my disk, deleted there, refreshed my Eclipse view, and updated the source. Error gone.
Fiddler2 -> Rules -> Custom Rules
then find function OnBeforeRequest on put in the next script at the end:
if (oSession.HostnameIs("mysite.com")){
oSession.host="localhost:39901";
}
Every time you call itr2.next() you are getting a distinct value. Not the same value. You should only call this once in the loop.
Iterator<String> itr2 = keys.iterator();
while(itr2.hasNext()){
String v = itr2.next();
System.out.println("Key: "+v+" ,value: "+m.get(v));
}
If your id is incremental then use something like
delete from table where id < (select max(id) from table)-N
There are a lot of great answers here, but this is the approach I took for an Appium test where acting on a single element can result in going to different application states based on the user's settings. While it doesn't follow the conventions of OP's example, I hope it helps someone.
public <T extends MobilePage> T tapSignInButton(Class<T> type) throws NoSuchMethodException, IllegalAccessException, InvocationTargetException, InstantiationException {
//signInButton.click();
return type.getConstructor(AppiumDriver.class).newInstance(appiumDriver);
}
If you don't want to throw the errors you can catch them like so:
public <T extends MobilePage> T tapSignInButton(Class<T> type) {
// signInButton.click();
T returnValue = null;
try {
returnValue = type.getConstructor(AppiumDriver.class).newInstance(appiumDriver);
} catch (Exception e) {
e.printStackTrace();
}
return returnValue;
}
Also you can add "<br/>"
instead of \n.
It's HTML escaped code for <br/>
And then you can add text to TexView:
articleTextView.setText(Html.fromHtml(textForTextView));

LESS_THAN_EQUAL(new String[]{"<="}),
GREATER_THAN(new String[]{">"}),
GREATER_THAN_EQUAL(new String[]{">="}),
EXISTS(new String[]{"not null", "exists"}),
NOT_EXISTS(new String[]{"is null", "not exists"}),
MATCH(new String[]{"match"});
private String[] value;
Operator(String[] value) {
this.value = value;
}
@JsonValue
public String toStringOperator(){
return value[0];
}
@JsonCreator
public static Operator fromStringOperator(String stringOperator) {
if(stringOperator != null) {
for(Operator operator : Operator.values()) {
for(String operatorString : operator.value) {
if (stringOperator.equalsIgnoreCase(operatorString)) {
return operator;
}
}
}
}
return null;
}
}

Using https sounds best option here (certificates are not that expensive nowadays). However if http is a requirement, you may use some encription - encript it on server side and decript in users browser (send key separately).
We have used that while implementing safevia.net - encription is done on clients (sender/receiver) sides, so users data are not available on network nor server layer.
A more explicit example, built on Damien's code (calls a test resource at http://httpbin.org/). For python3. Note that if the server redirects to another URL, uri
in add_password
has to contain the new root URL (it's possible to pass a list of URLs, also).
import ssl
import urllib.parse
import urllib.request
def get_resource(uri, user, passwd=False):
"""
Get the content of the SSL page.
"""
uri = 'https://httpbin.org/basic-auth/user/passwd'
user = 'user'
passwd = 'passwd'
context = ssl.create_default_context()
context.check_hostname = False
context.verify_mode = ssl.CERT_NONE
password_mgr = urllib.request.HTTPPasswordMgrWithDefaultRealm()
password_mgr.add_password(None, uri, user, passwd)
auth_handler = urllib.request.HTTPBasicAuthHandler(password_mgr)
opener = urllib.request.build_opener(auth_handler, urllib.request.HTTPSHandler(context=context))

I decided to download the assigned port numbers from IANA, filter out the used ports, and sort each "Unassigned" range in order of most ports available, descending. This did not work, since the csv file has ranges marked as "Unassigned" that overlap other port number reservations. I manually expanded the ranges of assigned port numbers, leaving me with a list of all assigned port numbers. I then sorted that list and generated my own list of unassigned ranges.
Since this stackoverflow.com page ranked very high in my search about the topic, I figured I'd post the largest ranges here for anyone else who is interested. These are for both TCP and UDP where the number of ports in the range is at least 500.

The JWT is stored on browser, so remove the token deleting the cookie at client side
If you need also to invalidate the token from server side before its expiration time, for example account deleted/blocked/suspended, password changed, permissions changed, user logged out by admin, take a look at Invalidating JSON Web Tokens for some commons techniques like creating a blacklist or rotating tokens
Something that could be implemented is static interface (instead of static method in an interface). All classes implementing a given static interface should implement the corresponding static methods. You could get static interface SI from any Class clazz using
SI si = clazz.getStatic(SI.class); // null if clazz doesn't implement SI
// alternatively if the class is known at compile time
SI si = Someclass.static.SI; // either compiler errror or not null
then you can call si.method(params)
.
This would be useful (for factory design pattern for example) because you can get (or check the implementation of) SI static methods implementation from a compile time unknown class !
A dynamic dispatch is necessary and you can override the static methods (if not final) of a class by extending it (when called through the static interface).
Obviously, these methods can only access static variables of their class.
This is very similar to mplungjan's answer, but can be a bit easier (especially if you need to do other string manipulation right after and want to keep it as an array) Anyway, I just thought I'd put it out there in case someone prefers it.
var str = 'a_b_c';_x000D_
str = str.split(''); //['a','_','b','_','c']_x000D_
str.splice(str.lastIndexOf('_'),1,'-'); //['a','_','b','-','c']_x000D_
str = str.join(''); //'a_b-c'
_x000D_
The '_' can be swapped out with the char you want to replace
And the '-' can be replaced with the char or string you want to replace it with

Each method of mysqli can fail. You should test each return value. If one fails, think about whether it makes sense to continue with an object that is not in the state you expect it to be. (Potentially not in a "safe" state, but I think that's not an issue here.)
Since only the error message for the last operation is stored per connection/statement you might lose information about what caused the error if you continue after something went wrong. You might want to use that information to let the script decide whether to try again (only a temporary issue), change something or to bail out completely (and report a bug). And it makes debugging a lot easier.
$stmt = $mysqli->prepare("INSERT INTO testtable VALUES (?,?,?)");
// prepare() can fail because of syntax errors, missing privileges, ....
if ( false===$stmt ) {
// and since all the following operations need a valid/ready statement object
// it doesn't make sense to go on
// you might want to use a more sophisticated mechanism than die()
// but's it's only an example
die('prepare() failed: ' . htmlspecialchars($mysqli->error));
}
$rc = $stmt->bind_param('iii', $x, $y, $z);
// bind_param() can fail because the number of parameter doesn't match the placeholders in the statement
// or there's a type conflict(?), or ....
if ( false===$rc ) {
// again execute() is useless if you can't bind the parameters. Bail out somehow.
die('bind_param() failed: ' . htmlspecialchars($stmt->error));
}
$rc = $stmt->execute();
// execute() can fail for various reasons. And may it be as stupid as someone tripping over the network cable
// 2006 "server gone away" is always an option
if ( false===$rc ) {
die('execute() failed: ' . htmlspecialchars($stmt->error));
}
$stmt->close();
The mysqli extension is perfectly capable of reporting operations that result in an (mysqli) error code other than 0 via exceptions, see mysqli_driver::$report_mode.
die() is really, really crude and I wouldn't use it even for examples like this one anymore.
So please, only take away the fact that each and every (mysql) operation can fail for a number of reasons; even if the exact same thing went well a thousand times before....
If you want to use enhanced loop, you can convert the string to charArray
for (char ch : exampleString.toCharArray()) {
System.out.println(ch);
}
Make it simple:
render(<BrowserRouter><Main /></BrowserRouter>, document.getElementById('root'));
and don't forget: import { BrowserRouter } from "react-router-dom";
Test if you are is safe mode - if not - set the time limit (Local Value) to what you want:
if(!ini_get('safe_mode')){
echo "safe mode off";
set_time_limit(180);// seconds
phpinfo();// see 'max_execution_time'
}
*You cannot set time limit this way if safe mode 'on'.
There is no difference between them.
If you don't specify a value for any of the half-dozen properties that background
is a shorthand for, then it is set to its default value. none
and transparent
are the defaults.
One explicitly sets the background-image
to none
and implicitly sets the background-color
to transparent
. The other is the other way around.
Customizing the Calendar and Date while Marshaling
Step 1 : Prepare jaxb binding xml for custom properties, In this case i prepared for date and calendar
<jaxb:bindings version="2.1" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<jaxb:globalBindings generateElementProperty="false">
<jaxb:serializable uid="1" />
<jaxb:javaType name="java.util.Date" xmlType="xs:date"
parseMethod="org.apache.cxf.tools.common.DataTypeAdapter.parseDate"
printMethod="com.stech.jaxb.util.CalendarTypeConverter.printDate" />
<jaxb:javaType name="java.util.Calendar" xmlType="xs:dateTime"
parseMethod="javax.xml.bind.DatatypeConverter.parseDateTime"
printMethod="com.stech.jaxb.util.CalendarTypeConverter.printCalendar" />
Setp 2 : Add custom jaxb binding file to Apache or any related plugins at xsd option like mentioned below
<xsdOption>
<xsd>${project.basedir}/src/main/resources/tutorial/xsd/yourxsdfile.xsd</xsd>
<packagename>com.tutorial.xml.packagename</packagename>
<bindingFile>${project.basedir}/src/main/resources/xsd/jaxbbindings.xml</bindingFile>
</xsdOption>
Setp 3 : write the code for CalendarConverter class
package com.stech.jaxb.util;
import java.text.SimpleDateFormat;
/**
* To convert the calendar to JaxB customer format.
*
*/
public final class CalendarTypeConverter {
/**
* Calendar to custom format print to XML.
*
* @param val
* @return
*/
public static String printCalendar(java.util.Calendar val) {
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss");
return simpleDateFormat.format(val.getTime());
}
/**
* Date to custom format print to XML.
*
* @param val
* @return
*/
public static String printDate(java.util.Date val) {
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd");
return simpleDateFormat.format(val);
}
}
Setp 4 : Output
<xmlHeader>
<creationTime>2014-09-25T07:23:05</creationTime> Calendar class formatted
<fileDate>2014-09-25</fileDate> - Date class formatted
</xmlHeader>
Here is all you need:
curl_setopt($curlHandle, CURLINFO_HEADER_OUT, true); // enable tracking
... // do curl request
$headerSent = curl_getinfo($curlHandle, CURLINFO_HEADER_OUT ); // request headers
I've created an example to show how to. Updated state
definition would be:
$stateProvider
.state('home', {
url: '/:foo?bar',
views: {
'': {
templateUrl: 'tpl.home.html',
controller: 'MainRootCtrl'
},
...
}
And this would be the controller:
.controller('MainRootCtrl', function($scope, $state, $stateParams) {
//..
var foo = $stateParams.foo; //getting fooVal
var bar = $stateParams.bar; //getting barVal
//..
$scope.state = $state.current
$scope.params = $stateParams;
})
What we can see is that the state home now has url defined as:
url: '/:foo?bar',
which means, that the params in url are expected as
/fooVal?bar=barValue
These two links will correctly pass arguments into the controller:
<a ui-sref="home({foo: 'fooVal1', bar: 'barVal1'})">
<a ui-sref="home({foo: 'fooVal2', bar: 'barVal2'})">
Also, the controller does consume $stateParams
instead of $stateParam
.
Link to doc:
You can check it here
params : {}
There is also new, more granular setting params : {}
. As we've already seen, we can declare parameters as part of url
. But with params : {}
configuration - we can extend this definition or even introduce paramters which are not part of the url:
.state('other', {
url: '/other/:foo?bar',
params: {
// here we define default value for foo
// we also set squash to false, to force injecting
// even the default value into url
foo: {
value: 'defaultValue',
squash: false,
},
// this parameter is now array
// we can pass more items, and expect them as []
bar : {
array : true,
},
// this param is not part of url
// it could be passed with $state.go or ui-sref
hiddenParam: 'YES',
},
...
Settings available for params are described in the documentation of the $stateProvider
Below is just an extract
We can call these params this way:
// hidden param cannot be passed via url
<a href="#/other/fooVal?bar=1&bar=2">
// default foo is skipped
<a ui-sref="other({bar: [4,5]})">

When compiling memcached under Centos 5.x i got the same problem.
The solution is to upgrade gcc and g++ to version 4.4 at least.
Make sure your CC/CXX is set (exported) to right binaries before compiling.
If what you want can't be achieved satisfactorily without having the initialization in its own method (e.g. because you want to do too much before the initialization code, or wrap it in a try-finally, or whatever) you can have any or all constructors pass the readonly variables by reference to an initialization routine, which will then be able to manipulate them at will.
public class Sample
{
private readonly int _intField;
public int IntProperty => _intField;
private void setupStuff(ref int intField, int newValue) => intField = newValue;
public Sample(string theIntAsString)
{
int i = int.Parse(theIntAsString);
setupStuff(ref _intField,i);
}
public Sample(int theInt) => setupStuff(ref _intField, theInt);
}
Try VAVR Tuples.
Not only does vavr have a good set of tuple types, it has great support for functional programming, too.
I find a far easier solution is to forget all the if
checks all over the place and just use ProGuard to strip out any Log.d()
or Log.v()
method calls when we call our Ant release
target.
That way, we always have the debug info being output for regular builds and don't have to make any code changes for release builds. ProGuard can also do multiple passes over the bytecode to remove other undesired statements, empty blocks and can automatically inline short methods where appropriate.
For example, here's a very basic ProGuard config for Android:
-dontskipnonpubliclibraryclasses
-dontobfuscate
-forceprocessing
-optimizationpasses 5
-keep class * extends android.app.Activity
-assumenosideeffects class android.util.Log {
public static *** d(...);
public static *** v(...);
}
So you would save that to a file, then call ProGuard from Ant, passing in your just-compiled JAR and the Android platform JAR you're using.
See also the examples in the ProGuard manual.
Update (4.5 years later): Nowadays I used Timber for Android logging.
Not only is it a bit nicer than the default Log
implementation — the log tag is set automatically, and it's easy to log formatted strings and exceptions — but you can also specify different logging behaviours at runtime.
In this example, logging statements will only be written to logcat in debug builds of my app:
Timber is set up in my Application
onCreate()
method:
if (BuildConfig.DEBUG) {
Timber.plant(new Timber.DebugTree());
}
Then anywhere else in my code I can log easily:
Timber.d("Downloading URL: %s", url);
try {
// ...
} catch (IOException ioe) {
Timber.e(ioe, "Bad things happened!");
}
See the Timber sample app for a more advanced example, where all log statements are sent to logcat during development and, in production, no debug statements are logged, but errors are silently reported to Crashlytics.
The table names are case-sensitive so you should use lower-case nat instead of upper-case NAT. For example;
iptables -t nat -A POSTROUTING -s 192.168.1.1/24 -o eth0 -j MASQUERADE
None of these solutions worked for me inside a Weebly "add your own html" box. Not sure what they are doing with their code. But I found this solution at https://benmarshall.me/responsive-iframes/ and it works perfectly.

There is one more way to use Java
import java.io._
def printToFile(f: java.io.File)(op: java.io.PrintWriter => Unit)
{
val p = new java.io.PrintWriter(f);
try { op(p) }
finally { p.close() }
}
printToFile(new File("C:/TEMP/df.csv")) { p => df.collect().foreach(p.println)}

namespace SerialReadTest
{
class SerialRead
{
static void Main(string[] args)
{
Console.WriteLine("Serial read init");
SerialPort port = new SerialPort("COM6", 115200, Parity.None, 8, StopBits.One);
port.Open();
while(true){
Console.WriteLine(port.ReadLine());
}
}
}
}
Here is what I would do:
find /path/to/dir -type f -iname "*filename*" -print0 | xargs -0 sed -i '/searchstring/s/old/new/g'
this will look for all files containing filename
in the file's name under the /path/to/dir
, than for every file found, search for the line with searchstring
and replace old
with new
.
Though if you want to omit looking for a specific file with a filename
string in the file's name, than simply do:
find /path/to/dir -type f -print0 | xargs -0 sed -i '/searchstring/s/old/new/g'
This will do the same thing above, but to all files found under /path/to/dir
.
I use guard let else
, so that can do some default stuff if the delegate func is not implemented.
@objc protocol ViewController2Delegate: NSObjectProtocol {
optional func viewController2(controller: ViewController2, didSomethingWithStringAndReturnVoid string: String)
optional func viewController2(controller: ViewController2, didSomethingWithStringAndReturnString string: String) -> String
}
class ViewController2: UIViewController {
weak var delegate: ViewController2Delegate?
@IBAction func onVoidButtonClicked(sender: AnyObject){
if (delegate != nil && delegate!.respondsToSelector(Selector("viewController2:didSomethingWithStringAndReturnVoid:"))) {
NSLog("ReturnVoid is implemented")
delegate!.viewController2!(self, didSomethingWithStringAndReturnVoid: "dummy")
}
else{
NSLog("ReturnVoid is not implemented")
// Do something by default
}
}
@IBAction func onStringButtonClicked(sender: AnyObject){
guard let result = delegate?.viewController2?(self, didSomethingWithStringAndReturnString: "dummy") else {
NSLog("ReturnString is not implemented")
// Do something by default
return
}
NSLog("ReturnString is implemented with result: \(result)")
}
}
To get the files in the classpath :
Resource resource = new ClassPathResource("countries.xml");
File file = resource.getFile();
To read the file onStartup use @PostConstruct
:
@Configuration
public class ReadFileOnStartUp {
@PostConstruct
public void afterPropertiesSet() throws Exception {
//Gets the XML file under src/main/resources folder
Resource resource = new ClassPathResource("countries.xml");
File file = resource.getFile();
//Logic to read File.
}
}
Here is a Small example for reading an XML File on Spring Boot App startup.
An example where things could go wrong with Shell=True is shown here
>>> from subprocess import call
>>> filename = input("What file would you like to display?\n")
What file would you like to display?
non_existent; rm -rf / # THIS WILL DELETE EVERYTHING IN ROOT PARTITION!!!
>>> call("cat " + filename, shell=True) # Uh-oh. This will end badly...
Check the doc here: subprocess.call()
To return a file or filepath
URL resource = YourClass.class.getResource("abc");
File file = Paths.get(resource.toURI()).toFile(); // return a file
String filepath = Paths.get(resource.toURI()).toFile().getAbsolutePath(); // return file path
on iOS Simulator,
Press Command + control + c
or from menu : Edit>Copy Screen
open "Preview" app, Press Command + n
or from menu : File> New from clipboard
, then you can save command+s
For Retina, activate iOS Simulator then on menu:
HardWare>Device>iPhone (Retina)
and follow above process
Command + S
is the way to save on Desktop, (on new iPhone simulators, this was introduced in later simulator)
I believe the easiest solution for finding the Nth occurrence of a String is to use StringUtils.ordinalIndexOf() from Apache Commons.
Example:
StringUtils.ordinalIndexOf("aabaabaa", "b", 2) == 5
We can use $set
operator to update the nested array inside object filed update the value
db.getCollection('geolocations').update(
{
"_id" : ObjectId("5bd3013ac714ea4959f80115"),
"geolocation.country" : "United States of America"
},
{ $set:
{
"geolocation.$.country" : "USA"
}
},
false,
true
);
TO ADD: @Christopher's answer does not work on API 7/8 (as per @Jonny's correct comment) IF you are using colours, instead of drawables. (In my testing, using drawables as per Christopher works fine)
Here is the FIX for 2.3 and below when using colours:
As per @Charles Harley, there is a bug in 2.3 and below where filling the list item with a colour causes the colour to flow out over the whole list. His fix is to define a shape
drawable containing the colour you want, and to use that instead of the colour.
I suggest looking at this link if you want to just use a colour as selector, and are targeting Android 2 (or at least allow for Android 2).
You can make this.

To get only own methods, and exclude inherited ones:
From within the instance:
self.methods - self.class.superclass.instance_methods
From outside:
TestClass.instance_methods - TestClass.superclass.instance_methods
Add it to the class:
class TestClass
class << self
def own_methods
self.instance_methods - self.superclass.instance_methods
end
end
end
TestClass.own_methods
=> [:method1, :method2, :method3]

Your BlockID
function uses the undefined variable images
, which will lead to an error. Also, you should not use an Array
here - JavaScripts key-value-maps are plain objects:
function BlockID() {
return {
"s": "Images/Block_01.png",
"g": "Images/Block_02.png",
"C": "Images/Block_03.png",
"d": "Images/Block_04.png"
};
}
To Start Jenkins through Command Line
Run CMD with admin
You can run following commands
"net start servicename" to start
"net restart servicename" to restart
"net stop servicename" to stop service
for more reference https://www.windows-commandline.com/start-stop-service-command-line/
Try this function instead.
string source = "My name is Marco and I'm from Italy";
string[] stringSeparators = new string[] {"is Marco and"};
var result = source.Split(stringSeparators, StringSplitOptions.None);
<img draggable="false" src="images/testimg1.jpg" alt=""/>
Drawing an image using a QLabel
seems like a bit of a kludge to me. With newer versions of Qt you can use a QGraphicsView
widget. In Qt Creator, drag a Graphics View
widget onto your UI and name it something (it is named mainImage
in the code below). In mainwindow.h
, add something like the following as private
variables to your MainWindow
class:
QGraphicsScene *scene;
QPixmap image;
Then just edit mainwindow.cpp
and make the constructor something like this:
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent), ui(new Ui::MainWindow)
{
ui->setupUi(this);
image.load("myimage.png");
scene = new QGraphicsScene(this);
scene->addPixmap(image);
scene->setSceneRect(image.rect());
ui->mainImage->setScene(scene);
}
Does this not work?
System.Reflection.MethodBase.GetCurrentMethod()

Use purrr::has_element
to check against the value of a list element:
> x <- list(c(1, 2), c(3, 4))
> purrr::has_element(x, c(3, 4))
[1] TRUE
> purrr::has_element(x, c(3, 5))
[1] FALSE
You can remove the entire line below:
.map((res: Response) => res.json());
No need to use the map method at all.
When doing recursive replacement, the path and filename need to be included:
Get-ChildItem -Recurse | ForEach { (Get-Content $_.PSPath |
ForEach {$ -creplace "old", "new"}) | Set-Content $_.PSPath }
This wil replace all "old" with "new" case-sensitive in all the files of your folders of your current directory.
From the Apple Developer Forum (account required):
"The compiler and linker are capable of using features and performing optimizations that do not work on older OS versions.
-mmacosx-version-min
tells the tools what OS versions you need to work with, so the tools can disable optimizations that won't run on those OS versions. If you need to run on older OS versions then you must use this flag."The downside to
-mmacosx-version-min
is that the app's performance may be worse on newer OS versions then it could have been if it did not need to be backwards-compatible. In most cases the differences are small."

Ok. Just to clarify this strictly has nothing to do with the declaration. It relates only to "jumping over the initialization" (ISO C++ '03 6.7/3)
A lot of the posts here have mentioned that jumping over the declaration may result in the variable "not being declared". This is not true. An POD object can be declared without an initializer but it will have an indeterminate value. For example:
switch (i)
{
case 0:
int j; // 'j' has indeterminate value
j = 0; // 'j' set (not initialized) to 0, but this statement
// is jumped when 'i == 1'
break;
case 1:
++j; // 'j' is in scope here - but it has an indeterminate value
break;
}
Where the object is a non-POD or aggregate the compiler implicitly adds an initializer, and so it is not possible to jump over such a declaration:
class A {
public:
A ();
};
switch (i) // Error - jumping over initialization of 'A'
{
case 0:
A j; // Compiler implicitly calls default constructor
break;
case 1:
break;
}
This limitation is not limited to the switch statement. It is also an error to use 'goto' to jump over an initialization:
goto LABEL; // Error jumping over initialization
int j = 0;
LABEL:
;
A bit of trivia is that this is a difference between C++ and C. In C, it is not an error to jump over the initialization.
As others have mentioned, the solution is to add a nested block so that the lifetime of the variable is limited to the individual case label.
select count(*) from dbo.tablename where address_line_1 LIKE '%[\'']%' {eSCAPE'\'}

Make sure your TextView width and height match (be the same in dp), if you want a perfect (unstretched) circle.
Make sure that the text fits into a circle, by either shortening your text OR enlarging your circle OR making your text size smaller OR reduce your padding/s, if any. OR a combination of the above suggestions.
[EDIT]
For what I can see in your pictures, you want to add too much text on a line, for pure circles.
Consider that the text should have a square aspect, so you can either wrap it (use \n
) or just put the numbers inside the circles and put the writings above or uder the corresponding circle.
You can add reference of Microsoft.Office.Core
from COM components tab in the add reference window by adding reference of Microsoft Office 12.0 Object Library
. The screen shot will shows what component you need.
Write this in your ViewDidLoad Method:
if ([self respondsToSelector:@selector(setEdgesForExtendedLayout:)]) {
self.edgesForExtendedLayout=UIRectEdgeNone;
self.extendedLayoutIncludesOpaqueBars=NO;
self.automaticallyAdjustsScrollViewInsets=NO;
}
It fixed status bar color for me and other UI misplacements also to a extent.
thelist.Max(e => e.age);
Alternatively to Link Library Dependencies
in project properties there is another way to link libraries in Visual Studio.
Add Existing Item...
).Item Type
is Library
This will include the other libraries in X as if you ran
lib /out:X.lib X.lib other1.lib other2.lib
You should use the OpenFileDialog class like this
Dim fd As OpenFileDialog = New OpenFileDialog()
Dim strFileName As String
fd.Title = "Open File Dialog"
fd.InitialDirectory = "C:\"
fd.Filter = "All files (*.*)|*.*|All files (*.*)|*.*"
fd.FilterIndex = 2
fd.RestoreDirectory = True
If fd.ShowDialog() = DialogResult.OK Then
strFileName = fd.FileName
End If
Then you can use the File class.
pattern: /[\w\W]{1,10}/g
I used this expression for my case, it includes all the characters available in the text.
I am using the code above but I have changed the delay effect by slideToggle.
It slides the dropdown on hover with animation.
$('.navbar .dropdown').hover(function() {
$(this).find('.dropdown-menu').first().stop(true, true).slideToggle(400);
}, function() {
$(this).find('.dropdown-menu').first().stop(true, true).slideToggle(400)
});
If you're using Spring framework already, use the following method:
import static org.springframework.web.util.HtmlUtils.htmlUnescape;
...
String result = htmlUnescape(source);
This is all you need, no wrapper needed:
.login-icon{
display:inline-block;
font-size: 40px;
line-height: 50px;
background-color:black;
color:white;
width: 50px;
height: 50px;
text-align: center;
vertical-align: bottom;
}
background-image: url(path-to-file/img.jpg);
background-repeat:no-repeat;
background-position: center center;
That should work.
If not, why not make a div
with the image and use z-index
to make it the background? This would be much easier to center than a background image on the body.
Other than that try:
background-position: 0 100px;/*use a pixel value that will center it*/
Or I think you can use 50% if you have set your body min-height
to 100%.
body{
background-repeat:no-repeat;
background-position: center center;
background-image:url(../images/images2.jpg);
color:#FFF;
font-family:Arial, Helvetica, sans-serif;
min-height:100%;
}
A double is an IEEE754 double-precision floating point number, similar to a float but with a larger range and precision.
IEEE754 single precision numbers have 32 bits (1 sign, 8 exponent and 23 mantissa bits) while double precision numbers have 64 bits (1 sign, 11 exponent and 52 mantissa bits).
A Double
in Java is the class version of the double basic type - you can use doubles but, if you want to do something with them that requires them to be an object (such as put them in a collection), you'll need to box them up in a Double
object.
Here is my solution for those who use hook
; If you are listing items in your grid and want to remove the selected item, you can use this solution.
var list = data.filter(form => form.id !== selectedRowDataId);
setData(list);
c1.set(2017, 12 , 01); //Ex: 1999 jan 20 //System.out.println("Date is : " + sdf.format(c1.getTime()));
c1.add(Calendar.MONTH, -2); // substract 1 month
System.out.println
("Date minus 1 month : "
+ sdf.format(c1.getTime()));
To build a result string exactly in the format you show, you can use this:
var sList = "";
$('input[type=checkbox]').each(function () {
sList += "(" + $(this).val() + "-" + (this.checked ? "checked" : "not checked") + ")";
});
console.log (sList);
However, I would agree with @SLaks, I think you should re-consider the structure into which you will store this in your database.
EDIT: Sorry, I mis-read the output format you were looking for. Here is an update:
var sList = "";
$('input[type=checkbox]').each(function () {
var sThisVal = (this.checked ? "1" : "0");
sList += (sList=="" ? sThisVal : "," + sThisVal);
});
console.log (sList);
You can't.
Interfaces define contracts that other objects implement and therefore have no state that needs to be initialized.
If you have some state that needs to be initialized, you should consider using an abstract base class instead.
Sorry, I read jsp not javascript. You need to do something like (note that this is a relative url and may be different depending on the url of the document this javascript is in):
document.location = 'path/to/servlet';
Where your servlet-mapping in web.xml looks something like this:
<servlet-mapping>
<servlet-name>someServlet</servlet-name>
<url-pattern>/path/to/servlet*</url-pattern>
</servlet-mapping>
You can also try doing this using one of many third party tools that are available for this.
Queries are great for simple searches but if you need to do more manipulation with data, search for references and such this is where you can do a much better job with these.
Also, these come in very handy when some objects are encrypted and you need to search for
I’m using ApexSQL Search which is free but there are also many more (also free) on the market such as Red Gate or SSMS Tool Pack.
You could also try this instead of a for
loop:
set count=0
:loop
set /a count=%count%+1
(Commands here)
if %count% neq 100 goto loop
(Commands after loop)
It's quite small and it's what I use all the time.
If you have installed Visual Studio on your machine then open the Visual Studio Developer Command Prompt and type the following command: clrver
It will list all the installed versions of .NET Framework on that machine.
This is equivalent to new Date().getTime()
in JavaScript :
Use the below statement to get the time in seconds.
SELECT cast(DATEDIFF(s, '1970-01-01 00:00:00.000', '2016-12-09 16:22:17.897' ) as bigint)
Use the below statement to get the time in milliseconds.
SELECT cast(DATEDIFF(s, '1970-01-01 00:00:00.000', '2016-12-09 16:22:17.897' ) as bigint) * 1000
Just simply add or die(mysqli_error($db));
at the end of your query, this will print the mysqli error.
mysqli_query($db,"INSERT INTO stockdetails (`itemdescription`,`itemnumber`,`sellerid`,`purchasedate`,`otherinfo`,`numberofitems`,`isitdelivered`,`price`) VALUES ('$itemdescription','$itemnumber','$sellerid','$purchasedate','$otherinfo','$numberofitems','$numberofitemsused','$isitdelivered','$price')") or die(mysqli_error($db));
As a side note I'd say you are at risk of mysql injection
, check here How can I prevent SQL injection in PHP?. You should really use prepared statements to avoid any risk.
Just insert $this->load->database();
in your model:
function order_summary_insert($data){
$this->load->database();
$this->db->insert('Customer_Orders',$data);
}
I disagree with the advice given here - even the reference for the accepted answer concludes:
You can of course use query string parameters with HTTPS, but don’t use them for anything that could present a security problem. For example, you could safely use them to identity part numbers or types of display like ‘accountview’ or ‘printpage’, but don’t use them for passwords, credit card numbers or other pieces of information that should not be publicly available.
So, no they aren't really safe...!
The hashes are just because your column width is not enough to display the "number".
About the sorting, you should review how you system region and language is configured. For the US region, Excel date input should be "5/17/2012" not "17/05/2012" (this 17-may-12).

If you want to use arrays as arguments, the following code works in Rails 4:
query = Order.where(uuid: uuids, id: ids)
Order.where(query.where_values.map(&:to_sql).join(" OR "))
#=> Order Load (0.7ms) SELECT "orders".* FROM "orders" WHERE ("orders"."uuid" IN ('5459eed8350e1b472bfee48375034103', '21313213jkads', '43ujrefdk2384us') OR "orders"."id" IN (2, 3, 4))
More information: OR queries with arrays as arguments in Rails 4.
How are you getting the value of "results"? Are you getting it via ResultSet.getDouble()? In that case, you can check ResultSet.wasNull()
.
With the use of the bootstrap 4 utilities you could horizontally center an element itself by setting the horizontal margins to 'auto'.
To set the horizontal margins to auto you can use mx-auto
. The m
refers to margin and the x
will refer to the x-axis (left+right) and auto
will refer to the setting. So this will set the left margin and the right margin to the 'auto' setting. Browsers will calculate the margin equally and center the element. The setting will only work on block elements so the display:block needs to be added and with the bootstrap utilities this is done by d-block
.
<button type="submit" class="btn btn-primary mx-auto d-block">Submit</button>
You can consider all browsers to fully support auto margin settings according to this answer Browser support for margin: auto so it's safe to use.
The bootstrap 4 class text-center
is also a very good solution, however it needs a parent wrapper element. The benefit of using auto margin is that it can be done directly on the button element itself.
this is for swift 4.2, 5 and 5+

I'm able to run an SQL query by piping it to SQL*Plus:
@echo select count(*) from table; | sqlplus username/password@database
Give
@echo execute some_procedure | sqlplus username/password@databasename
a try.
If you have missed to add unique to DB column, just add this validation in model to check if the field is unique:
class Person < ActiveRecord::Base
validates_uniqueness_of :user_name
end
refer here Above is for testing purpose only, please add index by changing DB column as suggested by @Nate
please refer this with index for more information
I was seeing this same error when trying to save an excel file. The code worked fine when I was using MS Office 2003, but after upgrading to MS Office 2007 I started seeing this. It would happen anytime I tried to save an Excel file to a server or remote fie share.
My solution, though rudimentary, worked well. I just had the program save the file locally, like to the user's C:\ drive. Then use the "System.IO.File.Copy(File, Destination, Overwrite)" method to move the file to the server. Then you can delete the file on the C:\ drive.
Works great, and simple. But admittedly not the most elegant approach.
Hope this helps! I was having a ton of trouble finding any solutions on the web till this idea popped into my head.
If you really need to use sys.path.insert, consider leaving sys.path[0] as it is:
sys.path.insert(1, path_to_dev_pyworkbooks)
This could be important since 3rd party code may rely on sys.path documentation conformance:
As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter.
The radio buttons are sent on form submit when they are checked only...
use isset()
if true then its checked otherwise its not
This worked for me:
sudo xcodebuild -license
If your goal is simply to iterate over the range of values for read-only purposes, an alternative is to wrap both vectors around a proxy (O(1)) instead of copying them (O(n)), so they are promptly seen as a single, contiguous one.
std::vector<int> A{ 1, 2, 3, 4, 5};
std::vector<int> B{ 10, 20, 30 };
VecProxy<int> AB(A, B); // ----> O(1)!
for (size_t i = 0; i < AB.size(); i++)
std::cout << AB[i] << " "; // ----> 1 2 3 4 5 10 20 30
Refer to https://stackoverflow.com/a/55838758/2379625 for more details, including the 'VecProxy' implementation as well as pros & cons.
It's better to avoid any kind of loops, just remove all elements directly like this:
$("#mytable > tbody").html("");
You can do this:
def active_action?(controller)
'active' if controller.remove('/') == controller_name
end
Now, you can use like this:
<%= link_to users_path, class: "some-class #{active_action? users_path}" %>
I think that this will do the trick:
table{
table-layout: fixed;
width: 300px;
}
You can also try Word Extractor tool. Word Extractor can be used with any file in your computer to separate the strings that contain human text / words from binary code (exe applications, DLLs).
I would like to recommend using the scrollTo plugin
http://demos.flesler.com/jquery/scrollTo/
You can the set scrollto by jquery css selector.
$('html,body').scrollTo( $(target), 800 );
I have had great luck with the accuracy of this plugin and its methods, where other methods of achieving the same effect like using .offset()
or .position()
have failed to be cross browser for me in the past. Not saying you can't use such methods, I'm sure there is a way to do it cross browser, I've just found scrollTo to be more reliable.
I had a similar issue but I was unable to use the UserAgent
class inside the fake_useragent
module. I was running the code inside a docker container
import requests
import ujson
import random
response = requests.get('https://fake-useragent.herokuapp.com/browsers/0.1.11')
agents_dictionary = ujson.loads(response.text)
random_browser_number = str(random.randint(0, len(agents_dictionary['randomize'])))
random_browser = agents_dictionary['randomize'][random_browser_number]
user_agents_list = agents_dictionary['browsers'][random_browser]
user_agent = user_agents_list[random.randint(0, len(user_agents_list)-1)]
I targeted the endpoint used in the module. This solution still gave me a random user agent however there is the possibility that the data structure at the endpoint could change.

I have encountered similar problem and my solution is much clear than above.
I simply used the pattern in @JsonFormat
annotation
Basically my class has a DateTime
field, so I put an annotation around the getter:
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
public DateTime getDate() {
return date;
}
I serialize the class with ObjectMapper
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JodaModule());
mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
ObjectWriter ow = mapper.writer();
try {
String logStr = ow.writeValueAsString(log);
outLogger.info(logStr);
} catch (IOException e) {
logger.warn("JSON mapping exception", e);
}

Way to clean out any old versions of gems.
sudo gem cleanup
If you just want to see a list of what would be removed you can use:
sudo gem cleanup -d
You can also cleanup just a specific gem by specifying its name:
sudo gem cleanup gemname
for remove specific version like 1.1.9 only
gem uninstall gemname --version 1.1.9
If you still facing some exception to install gem, like:
invalid gem: package is corrupt, exception while verifying: undefined method `size' for nil:NilClass (NoMethodError) in /home/rails/.rvm/gems/ruby-2.1.1@project/cache/nokogiri-1.6.6.2.gem
the, you can remove it from cache:
rm /home/rails/.rvm/gems/ruby-2.1.1@project/cache/nokogiri-1.6.6.2.gem
For more detail:
http://blog.grepruby.com/2015/04/way-to-clean-up-gem-or-remove-old.html
jQuery Ajax loader is not working well when you call two APIs simultaneously. To resolve this problem you have to call the APIs one by one using the isAsync
property in Ajax setting. You also need to make sure that there should not be any error in the setting. Otherwise, the loader will not work. E.g undefined content-type, data-type for POST/PUT/DELETE/GET call.
Use the CSS function from jQuery to set styles to your items :
$('#buttonId').css({ "background-color": 'brown'});
For some reason, radhoo's solution wouldn't work for me. When I used the following expression:
$query = "INSERT INTO uradmonitor (db_value1, db_value2) VALUES (".
(($val1=='')?"NULL":("'".$val1."'")) . ", ".
(($val2=='')?"NULL":("'".$val2."'")) .
")";
'null' (with quotes) was inserted instead of null without quotes, making it a string instead of an integer. So I finally tried:
$query = "INSERT INTO uradmonitor (db_value1, db_value2) VALUES (".
(($val1=='')? :("'".$val1."'")) . ", ".
(($val2=='')? :("'".$val2."'")) .
")";
The blank resulted in the correct null (unquoted) being inserted into the query.
As lassevk suggests, write out the new file as you go, here is some example code:
fin = open("a.txt")
fout = open("b.txt", "wt")
for line in fin:
fout.write( line.replace('foo', 'bar') )
fin.close()
fout.close()
From the documentation (help copy-item -full
):
-force <SwitchParameter>
Allows cmdlet to override restrictions such as renaming existing files as long as security is not compromised.
Required? false
Position? named
Default value False
Accept pipeline input? false
Accept wildcard characters? false
My issue was that end users would start typing in a textbox and receive autocomplete (ACP) suggestions and update the calling control if a suggestion was selected as the ACP is designed by default. However, I also needed to update multiple other controls (textboxes, DropDowns, etc...) with data specific to the end user's selection. I have been trying to figure out an elegant solution to the issue and I feel the one I developed is worth sharing and hopefully will save you at least some time.

It is possible to use full C# 6.0 features in Visual Studio 2013 if you have Resharper.
You have to enable Resharper Build and voilá!
In Resharper Options -> Build - enable Resharper Build and in "Use MSBuild.exe version" choose "Latest Installed"
This way Resharper is going to build your C# 6.0 Projects and will also not underline C# 6.0 code as invalid.
I am also using this although I have Visual Studio 2015 because:
I am putting this here, as I was looking for a solution for this problem for some time now and maybe it will help someone else.
Python 2.5+:
python --version
Python 2.4-:
python -c 'import sys; print(sys.version)'
1) Create ViewHolder that does nothing :)
// SampleHolder.java
public class SampleHolder extends RecyclerView.ViewHolder {
public SampleHolder(View itemView) {
super(itemView);
}
}
2) Again create RecyclerView that does nothing :)
// SampleRecycler.java
public class SampleRecycler extends RecyclerView.Adapter<SampleHolder> {
@Override
public SampleHolder onCreateViewHolder(ViewGroup parent, int viewType) {
return null;
}
@Override
public void onBindViewHolder(SampleHolder holder, int position) {
}
@Override
public int getItemCount() {
return 0;
}
}
3) Now when your real recycler is not ready just use the sample one like below.
RecyclerView myRecycler = (RecyclerView) findViewById(R.id.recycler_id);
myRecycler.setLayoutManager(new LinearLayoutManager(this));
myRecycler.setAdapter(new SampleRecycler());
This is not best solution though but it works! Hope this is helpful.
//sort by number
bool sortByStartNumber(Player &p1, Player &p2) {
return p1.getStartNumber() < p2.getStartNumber();
}
//sort by string
bool sortByName(Player &p1, Player &p2) {
string s1 = p1.getFullName();
string s2 = p2.getFullName();
return s1.compare(s2) == -1;
}
Put a black, semitransparent, div on top of it.
Within the parent, you can reference the child using @ViewChild. When needed (i.e. when the event would be fired), you can just execute a method in the child from the parent using the @ViewChild reference.
You can use the approach @Ken Chan mentions, and add a single line of code after that if you want a specific list of Objects, example:
session.createCriteria(SomeTable.class)
.add(Restrictions.ge("someColumn", xxxxx))
.setProjection(Projections.projectionList()
.add(Projections.groupProperty("someColumn"))
.add(Projections.max("someColumn"))
.add(Projections.min("someColumn"))
.add(Projections.count("someColumn"))
).setResultTransformer(Transformers.aliasToBean(SomeClazz.class));
List<SomeClazz> objectList = (List<SomeClazz>) criteria.list();
this is what I use for a cross-platform code:
#ifdef _WIN32
#include <Windows.h>
#else
#include <unistd.h>
#endif
int main()
{
pollingDelay = 100
//do stuff
//sleep:
#ifdef _WIN32
Sleep(pollingDelay);
#else
usleep(pollingDelay*1000); /* sleep for 100 milliSeconds */
#endif
//do stuff again
return 0;
}
If you are already using jQuery UI in your project, you can use the built-in datepicker method for formatting your date object:
$.datepicker.formatDate('yy-mm-dd', new Date(2007, 1 - 1, 26));
However, the datepicker only formats dates, and cannot format times.
Have a look at jQuery UI datepicker formatDate, the examples.
$parts = preg_split('/\s+/', $str);
Recursion gets a bad rep, I'm always surprised by the number of developers that wont even touch recursion because someone told them it was evil incarnate.
I've learned through trial and error that when done properly recursion can be one of the fastest ways to iterate over something, it is not a steadfast rule and each language/ compiler/ engine has it's own quirks so mileage will vary.
In javascript I can reliably speed up almost any iterative process by introducing recursion with the added benefit of reducing side effects and making the code more clear concise and reusable. Also pro tip its possible to get around the stack overflow issue (and no you dont disable the warning).
My personal Pros & Cons:
Pros:
- Reduces side effects.
- Makes code more concise and easier to reason about.
- Reduces system resource usage and performs better than the traditional for loop.
Cons:
- Can lead to stack overflow.
- More complicated to setup than a traditional for loop.
Mileage will vary depending on language/ complier/ engine.
This is one of the possible solutions to implementing an OKHTTP post request without a request body.
RequestBody reqbody = RequestBody.create(null, new byte[0]);
Request.Builder formBody = new Request.Builder().url(url).method("POST",reqbody).header("Content-Length", "0");
clientOk.newCall(formBody.build()).enqueue(OkHttpCallBack());
No need to uninstall old python versions.
Just install new version say python-3.3.2-macosx10.6.dmg and change the soft link of python to newly installed python3.3
Check the path of default python and python3.3 with following commands
"which python" and "which python3.3"
then delete existing soft link of python and point it to python3.3
I use:
@ComponentScan(basePackages = {"com.package1","com.package2","com.package3", "com.packagen"})
how do I find out what is referencing System.Web.WebPages.Razor v2.0.0.0?
Just read your exception stacktrace:
Calling assembly : Microsoft.Web.Helpers, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
So it seems that you are using the Microsoft.Web.Helpers
which in turn depends on System.Web.WebPages.Razor, Version=2.0.0.0
.
You can add .dll file manually. For example if you want to add a dll file in your WPF application, and you are unable to refer it in your project
(Getting error :A reference to the "....dll" could not be added.Please make sure that the file is accessible and that it is a valid assembly or COM component) ,
then COPY that dll file and PASTE in the INSTALLER PROJECT (in application folder).
You can use lftp interactively in a shell script so the password not saved in .bash_history or similar by doing the following:
vi test_script.sh
Add the following to your file:
#!/bin/sh
HOST=<yourhostname>
USER=<someusername>
PASSWD=<yourpasswd>
cd <base directory for your put file>
lftp<<END_SCRIPT
open sftp://$HOST
user $USER $PASSWD
put local-file.name
bye
END_SCRIPT
And write/quit the vi editor after you edit the host, user, pass, and directory for your put file typing :wq
.Then make your script executable chmod +x test_script.sh
and execute it ./test_script.sh
.
One possible solution in C++ satisfying the O(N*log(N)) time complexity requirement would be as follows.
#include <algorithm>
vector<int> merge(vector<int>left, vector<int>right, int &counter)
{
vector<int> result;
vector<int>::iterator it_l=left.begin();
vector<int>::iterator it_r=right.begin();
int index_left=0;
while(it_l!=left.end() || it_r!=right.end())
{
// the following is true if we are finished with the left vector
// OR if the value in the right vector is the smaller one.
if(it_l==left.end() || (it_r!=right.end() && *it_r<*it_l) )
{
result.push_back(*it_r);
it_r++;
// increase inversion counter
counter+=left.size()-index_left;
}
else
{
result.push_back(*it_l);
it_l++;
index_left++;
}
}
return result;
}
vector<int> merge_sort_and_count(vector<int> A, int &counter)
{
int N=A.size();
if(N==1)return A;
vector<int> left(A.begin(),A.begin()+N/2);
vector<int> right(A.begin()+N/2,A.end());
left=merge_sort_and_count(left,counter);
right=merge_sort_and_count(right,counter);
return merge(left, right, counter);
}
It differs from a regular merge sort only by the counter.
A form is not allowed to be a child element of a table
, tbody
or tr
. Attempting to put one there will tend to cause the browser to move the form to it appears after the table (while leaving its contents — table rows, table cells, inputs, etc — behind).
You can have an entire table inside a form. You can have a form inside a table cell. You cannot have part of a table inside a form.
Use one form around the entire table. Then either use the clicked submit button to determine which row to process (to be quick) or process every row (allowing bulk updates).
HTML 5 introduces the form
attribute. This allows you to provide one form per row outside the table and then associate all the form control in a given row with one of those forms using its id
.
Add the following line in MyApplicationDir\gradle.properties
org.gradle.jvmargs=-Xmx1024m
This is how you do it
SELECT ID,NAME, (C_COUNTS+F_COUNTS) AS SUM_COUNTS
FROM TABLE
ORDER BY SUM_COUNTS LIMIT 20
The SUM function will add up all rows, so the order by
clause is useless, instead you will have to use the group by
clause.
Currently, your enum
is nested inside of your Card
class. All you have to do is move the definition of the enum
out of the class:
// A better name which follows conventions instead of card_suits is
public enum CardSuit
{
Clubs,
Hearts,
Spades,
Diamonds
}
public class Card
{
}
To Specify:
The name change from card_suits
to CardSuit
was suggested because Microsoft guidelines suggest Pascal Case for Enumerations and the singular form is more descriptive in this case (as a plural would suggest that you're storing multiple enumeration values by ORing them together).
If you are using Eclipse then you can do this by specifying the required size for the particular application in its Run Configuration's VM Arguments as EX: -Xms128m -Xmx512m
Or if you want all applications running from your eclipse to have the same specified size then you can specify this in the eclipse.ini
file which is present in your Eclipse home directory.
To get the size of the JVM during Runtime you can use Runtime.totalMemory()
which returns the total amount of memory in the Java virtual machine, measured in bytes.
As noted in a prior answer, although git merge-base
works,
$ git merge-base myfeature develop
050dc022f3a65bdc78d97e2b1ac9b595a924c3f2
If myfeature
is the current branch, as is common, you can use --fork-point
:
$ git merge-base --fork-point develop
050dc022f3a65bdc78d97e2b1ac9b595a924c3f2
This argument works only in sufficiently recent versions of git. Unfortunately it doesn't always work, however, and it is not clear why. Please refer to the limitations noted toward the end of this answer.
For full commit info, consider:
$ git log -1 $(git merge-base --fork-point develop)
It is probably better to create a dedicated function to create the link so you can avoid creating two anonymous functions. Thus:
<div id="div"></div>
<script>
function getLink(id)
{
var link = document.createElement('a');
link.setAttribute('href', '#');
link.innerHTML = id;
link.onclick = function()
{
onClickLink(id);
};
link.style.display = 'block';
return link;
}
var div = document.getElementById('div');
for (var i = 0; i < 10; i += 1)
{
div.appendChild(getLink(i.toString()));
}
</script>
Although in both cases you end up with two functions, I just think it is better to wrap it in a function that is semantically easier to comprehend.
head or tail can do it as well:
head -c X
Prints the first X bytes (not necessarily characters if it's a UTF-16 file) of the file. tail will do the same, except for the last X bytes.
This (and cut) are portable.
The cause is that the remote peer closes its socket (crash for example), so if you try to write data to him for example, you will get this. to solve that, protect read/write to socket operations between (try catch), then manage the lose connection case into the catch (renew connection, stop program, ...etc):
try {
/* your code */
} catch (SocketException e) {
e.printStackTrace();
/* insert your failure processings here */
}
I finally got this working.
I think the fact that our project had two different versions of the commons-httpclient jar wasn't helping. Once I sorted that out I found you can do two things...
In code you can put the following:
HttpComponentsClientHttpRequestFactory rf =
(HttpComponentsClientHttpRequestFactory) restTemplate.getRequestFactory();
rf.setReadTimeout(1 * 1000);
rf.setConnectTimeout(1 * 1000);
The first time this code is called it will set the timeout for the HttpComponentsClientHttpRequestFactory
class used by the RestTemplate
. Therefore, all subsequent calls made by RestTemplate
will use the timeout settings defined above.
Or the better option is to do this:
<bean id="RestOperations" class="org.springframework.web.client.RestTemplate">
<constructor-arg>
<bean class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory">
<property name="readTimeout" value="${application.urlReadTimeout}" />
<property name="connectTimeout" value="${application.urlConnectionTimeout}" />
</bean>
</constructor-arg>
</bean>
Where I use the RestOperations
interface in my code and get the timeout values from a properties file.
Oh my. This is actually so simple!

In the case where I have a fairly complex MultiIndex
, I think I prefer the groupby
approach. Here's simple example for posterity:
import numpy as np
import pandas
# fake index
idx = pandas.MultiIndex.from_tuples([('a', letter) for letter in list('abcde')])
# random data + naming the index levels
df1 = pandas.DataFrame(np.random.normal(size=(5,2)), index=idx, columns=['colA', 'colB'])
df1.index.names = ['iA', 'iB']
# artificially append some duplicate data
df1 = df1.append(df1.select(lambda idx: idx[1] in ['c', 'e']))
df1
# colA colB
#iA iB
#a a -1.297535 0.691787
# b -1.688411 0.404430
# c 0.275806 -0.078871
# d -0.509815 -0.220326
# e -0.066680 0.607233
# c 0.275806 -0.078871 # <--- dup 1
# e -0.066680 0.607233 # <--- dup 2
and here's the important part
# group the data, using df1.index.names tells pandas to look at the entire index
groups = df1.groupby(level=df1.index.names)
groups.last() # or .first()
# colA colB
#iA iB
#a a -1.297535 0.691787
# b -1.688411 0.404430
# c 0.275806 -0.078871
# d -0.509815 -0.220326
# e -0.066680 0.607233
I have Tried something Like this and it worked really fine with me
Socket Skt;
String host = "localhost";
int i = 8983; // port no.
try {
System.out.println("Looking for "+ i);
Skt = new Socket(host, i);
System.out.println("There is a Server on port "
+ i + " of " + host);
}
catch (UnknownHostException e) {
System.out.println("Exception occured"+ e);
}
catch (IOException e) {
System.out.println("port is not used");
}
Another useful command would be git diff-tree <hash>
where hash can be also a hash range (denoted by <old>..<new>
notation). An output example:
$ git diff-tree HEAD
:040000 040000 8e09a be406 M myfile
The fields are:
source mode, dest mode, source hash, dest hash, status, filename
Statuses are the ones you would expect: D (deleted), A (added), M (modified) etc. See man page for full description.
or you can
SELECT
String_to_array(CASE
WHEN <condition 1> THEN a1||','||b1
WHEN <condition 2> THEN a2||','||b2
ELSE a3||','||b3
END, ',') K
FROM <table>
If you use "Git for Windows"
>cd c:\Program Files\Git\etc\ssh\
add to ssh_config following:
AddKeysToAgent yes
IdentityFile ~/.ssh/id_rsa
IdentityFile ~/.ssh/id_rsa_test
ps. you need ssh version >= 7.2 (date of release 2016-02-28)
I am a programmer who has to deal with a lot of code on a daily basis. Open source and what has been developed in house.
As a programmer, I find it useful to have many source files open at once, and often organise my desktop on my (widescreen) monitor so that two source files are side by side. I might be programming in both, or just reading one and programming in the other.
I find it dissatisfying and frustrating when one of those source files is >120 characters in width, because it means I can't comfortably fit a line of code on a line of screen. It upsets formatting to line wrap.
I say '120' because that's the level to which I would get annoyed at code being wider than. After that many characters, you should be splitting across lines for readability, let alone coding standards.
I write code with 80 columns in mind. This is just so that when I do leak over that boundary, it's not such a bad thing.
In my opinion the best tool for such testing is curl. Its --upload-file
option uploads a file by PUT
, which is exactly what you want (and it can do much more, like modifying HTTP headers, in case you need it):
curl http://myservice --upload-file file.txt
I solved my problem of reading portuguese characters, changing the source file on notepad++.
C#
var url = System.Web.HttpContext.Current.Server.MapPath(@"~/Content/data.json");
string s = string.Empty;
using (System.IO.StreamReader sr = new System.IO.StreamReader(url, System.Text.Encoding.UTF8,true))
{
s = sr.ReadToEnd();
}
import UIKit
class ViewController: UIViewController{
@IBOutlet weak var webView: UIWebView!
override func viewDidLoad() {
super.viewDidLoad()
//Func Gose Here
loadUrl()
}
func loadUrl(){
let url = URL(string: "Url which you want to load(www.google.com)")
let requestObj = URLRequest(url: url! as URL)
webView.load(requestObj)
}
}
From your question it is unclear if you want to be able use the class without an identity or if calling the method requires you to create an instance of the class. This depends on whether you want the printInformation member to write some general information or more specific about the object identity.
Case 1: You want to use the class without creating an instance. The members of that class should be static, using this keyword you tell the compiler that you want to be able to call the method without having to create a new instance of the class.
class MyClass
{
public:
static void printInformation();
};
Case 2: You want the class to have an instance, you first need to create an object so that the class has an identity, once that is done you can use the object his methods.
Myclass m;
m.printInformation();
// Or, in the case that you want to use pointers:
Myclass * m = new Myclass();
m->printInformation();
If you don't know when to use pointers, read Pukku's summary in this Stack Overflow question.
Please note that in the current case you would not need a pointer. :-)
My solution ( may not work for you)
Open the application on a machine that is flagging the error. Change the VB code in some way. ( I added one comment line of code of no consequence into one of the macros)
Sheets(sheetName).Select 'comment of no consequence
and save it. This causes a recompile. Close and re-open - all fixed.
Hope this makes sense and helps

Please see below an example how to add white noise to the rendered texture. The solution is to use two textures: original and pure white noise, like this one: wiki white noise
private static final String VERTEX_SHADER =
"uniform mat4 uMVPMatrix;\n" +
"uniform mat4 uMVMatrix;\n" +
"uniform mat4 uSTMatrix;\n" +
"attribute vec4 aPosition;\n" +
"attribute vec4 aTextureCoord;\n" +
"varying vec2 vTextureCoord;\n" +
"varying vec4 vInCamPosition;\n" +
"void main() {\n" +
" vTextureCoord = (uSTMatrix * aTextureCoord).xy;\n" +
" gl_Position = uMVPMatrix * aPosition;\n" +
"}\n";
private static final String FRAGMENT_SHADER =
"precision mediump float;\n" +
"uniform sampler2D sTextureUnit;\n" +
"uniform sampler2D sNoiseTextureUnit;\n" +
"uniform float uNoseFactor;\n" +
"varying vec2 vTextureCoord;\n" +
"varying vec4 vInCamPosition;\n" +
"void main() {\n" +
" gl_FragColor = texture2D(sTextureUnit, vTextureCoord);\n" +
" vec4 vRandChosenColor = texture2D(sNoiseTextureUnit, fract(vTextureCoord + uNoseFactor));\n" +
" gl_FragColor.r += (0.05 * vRandChosenColor.r);\n" +
" gl_FragColor.g += (0.05 * vRandChosenColor.g);\n" +
" gl_FragColor.b += (0.05 * vRandChosenColor.b);\n" +
"}\n";
The fragment shared contains parameter uNoiseFactor which is updated on every rendering by main application:
float noiseValue = (float)(mRand.nextInt() % 1000)/1000;
int noiseFactorUniformHandle = GLES20.glGetUniformLocation( mProgram, "sNoiseTextureUnit");
GLES20.glUniform1f(noiseFactorUniformHandle, noiseFactor);
To be verbose it the removal of extension is demonstrated for workbooks.. which now have a variety of extensions . . a new unsaved Book1 has no ext . works the same for files
Function WorkbookIsOpen(FWNa$, Optional AnyExt As Boolean = False) As Boolean

FWNa = Trim(FWNa)
If FWNa <> "" Then
For Each wWB In Workbooks
WBNa = wWB.Name
If AnyExt Then
PD = InStr(WBNa, ".")
If PD > 0 Then WBNa = Left(WBNa, PD - 1)
PD = InStr(FWNa, ".")
If PD > 0 Then FWNa = Left(FWNa, PD - 1)
'
' the alternative of using split.. see commented out below
' looks neater but takes a bit longer then the pair of instr and left
' VBA does about 800,000 of these small splits/sec
' and about 20,000,000 Instr Lefts per sec
' of course if not checking for other extensions they do not matter
' and to any reasonable program
' THIS DISCUSSIONOF TIME TAKEN DOES NOT MATTER
' IN doing about doing 2000 of this routine per sec
' WBNa = Split(WBNa, ".")(0)
'FWNa = Split(FWNa, ".")(0)
End If
If WBNa = FWNa Then
WorkbookIsOpen = True
Exit Function
End If
Next wWB

Simpler with OUT
parameters:
CREATE OR REPLACE FUNCTION get_object_fields(_school_id int
, OUT user1_id int
, OUT user1_name varchar(32)
, OUT user2_id int
, OUT user2_name varchar(32)) AS
$func$
BEGIN
SELECT INTO user1_id, user1_name
u.id, u.name
FROM users u
WHERE u.school_id = _school_id
LIMIT 1; -- make sure query returns 1 row - better in a more deterministic way?
user2_id := user1_id + 1; -- some calculation
SELECT INTO user2_name
u.name
FROM users u
WHERE u.id = user2_id;
END
$func$ LANGUAGE plpgsql;
Call:
SELECT * FROM get_object_fields(1);
You don't need to create a type just for the sake of this plpgsql function. It may be useful if you want to bind multiple functions to the same composite type. Else, OUT
parameters do the job.
There is no RETURN
statement. OUT
parameters are returned automatically with this form that returns a single row. RETURN
is optional.
Since OUT
parameters are visible everywhere inside the function body (and can be used just like any other variable), make sure to table-qualify columns of the same name to avoid naming conflicts! (Better yet, use distinct names to begin with.)
Typically, this can be simpler and faster if queries in the function body can be combined. And you can use RETURNS TABLE()
(since Postgres 8.4, long before the question was asked) to return 0-n rows.
The example from above can be written as:
CREATE OR REPLACE FUNCTION get_object_fields2(_school_id int)
RETURNS TABLE (user1_id int
, user1_name varchar(32)
, user2_id int
, user2_name varchar(32)) AS
$func$
BEGIN
RETURN QUERY
SELECT u1.id, u1.name, u2.id, u2.name
FROM users u1
JOIN users u2 ON u2.id = u1.id + 1
WHERE u1.school_id = _school_id
LIMIT 1; -- may be optional
END
$func$ LANGUAGE plpgsql;
Call:
SELECT * FROM get_object_fields2(1);
RETURNS TABLE
is effectively the same as having a bunch of OUT
parameters combined with RETURNS SETOF record
, just shorter.
The major difference: this function can return 0, 1 or many rows, while the first version always returns 1 row.
Add LIMIT 1
like demonstrated to only allow 0 or 1 row.
RETURN QUERY
is simple way to return results from a query directly.
You can use multiple instances in a single function to add more rows to the output.
db<>fiddle here (demonstrating both)
If your function is supposed to dynamically return results with a different row-type depending on the input, read more here:
In the case of Windows 10 this is not exactly accurate, in fact none of the answers on stackoverflow was, I found this out when I tried to use pixel art as an icon and it got rescaled when it was not supposed to(it was easy to see in this case cause of the interpolation and smoothing windows does) even thou I used the sizes from this post.
So I made an app and did the work on all DPI settings, see it here:
Windows 10 all icon resolutions on all DPI settings
You can also use my app to create icons, also with nearest neighbor interpolation with smoothing off, which is not done with any of the bad editors I have seen.
If you only want the resolutions:
16, 20, 24, 28, 30, 31, 32, 40, 42, 47, 48, 56, 60, 63, 84, 256
and you should use all PNG icons and anything you put in beside these it won't be displayed. See my post why.
My issue was that I was using 'React.PureComponent' when I should have been using 'React.Component'.
To avoid leaving the file open, it is best to pass a block to File.open. This way, the file will be closed after the block executes.
contents = File.open('path-to-file.tar.gz', 'rb') { |f| f.read }
The error message suggests this is not a supported feature in the query language. But you can save a DataFrame in any format as usual through the RDD interface (df.rdd.saveAsTextFile
). Or you can check out https://github.com/databricks/spark-csv.
In my case, for some reason, vendor
folder was disabled on VS Code settings:
"intelephense.files.exclude": [
"**/.git/**",
"**/.svn/**",
"**/.hg/**",
"**/CVS/**",
"**/.DS_Store/**",
"**/node_modules/**",
"**/bower_components/**",
"**/vendor/**", <-- remove this line!
"**/resources/views/**"
],
By removing the line containing vendor
folder it works ok on version Intelephense 1.5.4
It means that using the bodyParser()
constructor has been deprecated, as of 2014-06-19.
app.use(bodyParser()); //Now deprecated
You now need to call the methods separately
app.use(bodyParser.urlencoded());
app.use(bodyParser.json());
And so on.
If you're still getting a warning with urlencoded
you need to use
app.use(bodyParser.urlencoded({
extended: true
}));
The extended
config object key now needs to be explicitly passed, since it now has no default value.
If you are using Express >= 4.16.0, body parser has been re-added under the methods express.json()
and express.urlencoded()
.
