If you are looking to create an instant messenger for Android, this code should get you started somewhere.
Excerpt from the source :
This is a simple IM application runs on Android, application makes http request to a server, implemented in php and mysql, to authenticate, to register and to get the other friends' status and data, then it communicates with other applications in other devices by socket interface.
EDIT : Just found this! Maybe it's not related to WhatsApp. But you can use the source to understand how chat applications are programmed.
There is a website called Scringo. These awesome people provide their own SDK which you can integrate in your existing application to exploit cool features like radaring, chatting, feedback, etc. So if you are looking to integrate chat in application, you could just use their SDK. And did I say the best part? It's free!
*UPDATE : * Scringo services will be closed down on 15 February, 2015.
If you are doing something for the web you need to use the js file extension:
import { moo } from 'file.js';
If you are doing something for nodejs I don't think use the js file extension:
import { moo } from 'file';
repartition
- it's recommended to use it while increasing the number of partitions, because it involve shuffling of all the data.
coalesce
- it's is recommended to use it while reducing the number of partitions. For example if you have 3 partitions and you want to reduce it to 2, coalesce
will move the 3rd partition data to partition 1 and 2. Partition 1 and 2 will remains in the same container.
On the other hand, repartition
will shuffle data in all the partitions, therefore the network usage between the executors will be high and it will impacts the performance.
coalesce
performs better than repartition
while reducing the number of partitions.
Please read the $.ajax
documentation, this is a covered topic.
$.ajax({
url: "test.html",
error: function(){
// will fire when timeout is reached
},
success: function(){
//do something
},
timeout: 3000 // sets timeout to 3 seconds
});
You can get see what type of error was thrown by accessing the textStatus parameter of the error: function(jqXHR, textStatus, errorThrown)
option. The options are "timeout", "error", "abort", and "parsererror".
Parameter names are normally not accessible by the Java code at runtime (because it's drop by the compiler), so if you want that functionality you need to either use Java 8's built-in functionality or use a library such as ParaNamer in order to gain access to it.
So in order to not having to utilize annotations for the constructor arguments when using Jackson, you can make use of either of these 2 Jackson modules:
This module allows you to get annotation-free constructor arguments when using Java 8. In order to use it you first need to register the module:
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new ParameterNamesModule());
Then compile your code using the -parameters flag:
javac -parameters ...
Link: https://github.com/FasterXML/jackson-modules-java8/tree/master/parameter-names
This other one simply requires you to register the module or configure an annotation introspection (but not both as pointed out by the comments). It allows you to use annotation-free constructor arguments on versions of Java prior to 1.8.
ObjectMapper mapper = new ObjectMapper();
// either via module
mapper.registerModule(new ParanamerModule());
// or by directly assigning annotation introspector (but not both!)
mapper.setAnnotationIntrospector(new ParanamerOnJacksonAnnotationIntrospector());
Link: https://github.com/FasterXML/jackson-modules-base/tree/master/paranamer
To have a consistent flow of the images on different devices, you'd have to specify the width and height value for each carousel image item, for instance here in my example the image would take the full width but with a height of "400px" (you can specify your personal value instead)
<div class="item">
<img src="image.jpg" style="width:100%; height: 400px;">
</div>
Am trying to grep pattern from dozen files .tar.gz but its very slow
tar -ztf file.tar.gz | while read FILENAME do if tar -zxf file.tar.gz "$FILENAME" -O | grep "string" > /dev/null then echo "$FILENAME contains string" fi done
That's actually very easy with ugrep option -z
:
-z, --decompress
Decompress files to search, when compressed. Archives (.cpio,
.pax, .tar, and .zip) and compressed archives (e.g. .taz, .tgz,
.tpz, .tbz, .tbz2, .tb2, .tz2, .tlz, and .txz) are searched and
matching pathnames of files in archives are output in braces. If
-g, -O, -M, or -t is specified, searches files within archives
whose name matches globs, matches file name extensions, matches
file signature magic bytes, or matches file types, respectively.
Supported compression formats: gzip (.gz), compress (.Z), zip,
bzip2 (requires suffix .bz, .bz2, .bzip2, .tbz, .tbz2, .tb2, .tz2),
lzma and xz (requires suffix .lzma, .tlz, .xz, .txz).
Which requires just one command to search file.tar.gz
as follows:
ugrep -z "string" file.tar.gz
This greps each of the archived files to display matches. Archived filenames are shown in braces to distinguish them from ordinary filenames. For example:
$ ugrep -z "Hello" archive.tgz
{Hello.bat}:echo "Hello World!"
Binary file archive.tgz{Hello.class} matches
{Hello.java}:public class Hello // prints a Hello World! greeting
{Hello.java}: { System.out.println("Hello World!");
{Hello.pdf}:(Hello)
{Hello.sh}:echo "Hello World!"
{Hello.txt}:Hello
If you just want the file names, use option -l
(--files-with-matches
) and customize the filename output with option --format="%z%~"
to get rid of the braces:
$ ugrep -z Hello -l --format="%z%~" archive.tgz
Hello.bat
Hello.class
Hello.java
Hello.pdf
Hello.sh
Hello.txt
Actually, the problem is that either /sys/kernel/debug
is not mounted, or that the running kernel has no ftrace tracers compiled in so that /sys/kernel/debug/tracing
is unavailable. This is the code throwing the error (platform_frameworks_native/libs/utils/Trace.cpp
):
void Tracer::init() {
Mutex::Autolock lock(sMutex);
if (!sIsReady) {
add_sysprop_change_callback(changeCallback, 0);
const char* const traceFileName =
"/sys/kernel/debug/tracing/trace_marker";
sTraceFD = open(traceFileName, O_WRONLY);
if (sTraceFD == -1) {
ALOGE("error opening trace file: %s (%d)", strerror(errno), errno);
sEnabledTags = 0; // no tracing can occur
} else {
loadSystemProperty();
}
android_atomic_release_store(1, &sIsReady);
}
}
The log message could definitely be a bit more informative.
There's a typo in your code (the tag a is closed too early). You can either use:
<a href="whatever" onclick="return confirm('are you sure?')"><img ...></a>
note the return (confirm): the value returned by scripts in intrinsic evens decides whether the default browser action is run or not; in case you need to run a big piece of code you can of course call another function:
<script type="text/javascript">
function confirm_delete() {
return confirm('are you sure?');
}
</script>
...
<a href="whatever" onclick="return confirm_delete()"><img ...></a>
(note that delete is a keyword)
For completeness: modern browsers also support DOM events, allowing you to register more than one handler for the same event on each object, access the details of the event, stop the propagation and much more; see DOM Events.

I wrote you 2 classes to show you how it's done; Main and Customer. If you run the Main class you see what's going on:
import java.util.*;
public class Customer {
private String name;
private String email;
public Customer(String name, String email) {
this.name = name;
this.email = email;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Override
public String toString() {
return name + " | " + email;
}
public static String toString(Collection<Customer> customers) {
String s = "";
for(Customer customer : customers) {
s += customer + "\n";
}
return s;
}
}
import java.util.*;
public class Main {
public static void main(String[] args) {
List<Customer> customers = new ArrayList<>();
customers.add(new Customer("Bert", "[email protected]"));
customers.add(new Customer("Ernie", "[email protected]"));
System.out.println("customers before email change - start");
System.out.println(Customer.toString(customers));
System.out.println("end");
customers.get(1).setEmail("[email protected]");
System.out.println("customers after email change - start");
System.out.println(Customer.toString(customers));
System.out.println("end");
}
}
to get this running, make 2 classes, Main and Customer and copy paste the contents from both classes to the correct class; then run the Main class.
DateTime.Now.ToString("HH:mm:ss tt");
this gives it to you as a string.

Horizontal scaling means that you scale by adding more machines into your pool of resources whereas Vertical scaling means that you scale by adding more power (CPU, RAM) to an existing machine.
An easy way to remember this is to think of a machine on a server rack, we add more machines across the horizontal direction and add more resources to a machine in the vertical direction.
In the database world, horizontal-scaling is often based on the partitioning of the data i.e. each node contains only part of the data, in vertical-scaling the data resides on a single node and scaling is done through multi-core i.e. spreading the load between the CPU and RAM resources of that machine.
With horizontal-scaling it is often easier to scale dynamically by adding more machines into the existing pool - Vertical-scaling is often limited to the capacity of a single machine, scaling beyond that capacity often involves downtime and comes with an upper limit.
Good examples of horizontal scaling are Cassandra, MongoDB, Google Cloud Spanner .. and a good example of vertical scaling is MySQL - Amazon RDS (The cloud version of MySQL). It provides an easy way to scale vertically by switching from small to bigger machines. This process often involves downtime.
In-Memory Data Grids such as GigaSpaces XAP, Coherence etc.. are often optimized for both horizontal and vertical scaling simply because they're not bound to disk. Horizontal-scaling through partitioning and vertical-scaling through multi-core support.
You can read more on this subject in my earlier posts: Scale-out vs Scale-up and The Common Principles Behind the NOSQL Alternatives
Is it a console program, running in Windows? If so, run it from a console you've already opened. i.e. run "cmd", then change to your directory that has the .exe in it (using the cd command), then type in the exe name. Your console window will stay open.
The accepted answer of how to create an Index inline a Table creation script did not work for me. This did:
CREATE TABLE [dbo].[TableToBeCreated]
(
[Id] BIGINT IDENTITY(1, 1) NOT NULL PRIMARY KEY
,[ForeignKeyId] BIGINT NOT NULL
,CONSTRAINT [FK_TableToBeCreated_ForeignKeyId_OtherTable_Id] FOREIGN KEY ([ForeignKeyId]) REFERENCES [dbo].[OtherTable]([Id])
,INDEX [IX_TableToBeCreated_ForeignKeyId] NONCLUSTERED ([ForeignKeyId])
)
Remember, Foreign Keys do not create Indexes, so it is good practice to index them as you will more than likely be joining on them.
With Bootstrap 4 .hidden-*
classes were completely removed (yes, they were replaced by hidden-*-*
but those classes are also gone from v4 alphas).
Starting with v4-beta, you can combine .d-*-none
and .d-*-block
classes to achieve the same result.
visible-* was removed as well; instead of using explicit .visible-*
classes, make the element visible by not hiding it (again, use combinations of .d-none .d-md-block). Here is the working example:
<div class="col d-none d-sm-block">
<span class="vcard">
…
</span>
</div>
<div class="col d-none d-xl-block">
<div class="d-none d-md-block">
…
</div>
<div class="d-none d-sm-block">
…
</div>
</div>
class="hidden-xs"
becomes class="d-none d-sm-block"
(or d-none d-sm-inline-block) ...
<span class="d-none d-sm-inline">hidden-xs</span>
<span class="d-none d-sm-inline-block">hidden-xs</span>
An example of Bootstrap 4 responsive utilities:
<div class="d-none d-sm-block"> hidden-xs
<div class="d-none d-md-block"> visible-md and up (hidden-sm and down)
<div class="d-none d-lg-block"> visible-lg and up (hidden-md and down)
<div class="d-none d-xl-block"> visible-xl </div>
</div>
</div>
</div>
<div class="d-sm-none"> eXtra Small <576px </div>
<div class="d-none d-sm-block d-md-none d-lg-none d-xl-none"> SMall =576px </div>
<div class="d-none d-md-block d-lg-none d-xl-none"> MeDium =768px </div>
<div class="d-none d-lg-block d-xl-none"> LarGe =992px </div>
<div class="d-none d-xl-block"> eXtra Large =1200px </div>
<div class="d-xl-none"> hidden-xl (visible-lg and down)
<div class="d-lg-none d-xl-none"> visible-md and down (hidden-lg and up)
<div class="d-md-none d-lg-none d-xl-none"> visible-sm and down (or hidden-md and up)
<div class="d-sm-none"> visible-xs </div>
</div>
</div>
</div>
Maven is not designed to work that way, but a workaround exists to achieve this goal (maybe with side effects, you will have to give a try). The trick is to tell the child project to find its parent via its relative path rather than its pure maven coordinates, and in addition to externalize the version number in a property :
<groupId>com.dummy.bla</groupId>
<artifactId>parent</artifactId>
<version>${global.version}</version>
<packaging>pom</packaging>
<properties>
<!-- Unique entry point for version number management -->
<global.version>0.1-SNAPSHOT</global.version>
</properties>
<parent>
<groupId>com.dummy.bla</groupId>
<artifactId>parent</artifactId>
<version>${global.version}</version>
<relativePath>..</relativePath>
</parent>
<groupId>com.dummy.bla.sub</groupId>
<artifactId>kid</artifactId>
I used that trick for a while for one of my project, with no specific problem, except the fact that maven logs a lot of warnings at the beginning of the build, which is not very elegant.
Seems maven 3.0.4 does not allow such a configuration anymore.
You shouldn't be setting x = []
. That is setting an empty list to your inputted parameter. Furthermore, use python's for i in x
syntax as follows:
for i in x:
if i.isalpha():
letters+=1
elif i.isnumeric():
digit+=1
elif i.isspace():
space+=1
else:
other+=1
It will look like this
<head>
<script type="text/javascript">
var image1 = new Image()
image1.src = "images/pentagg.jpg"
var image2 = new Image()
image2.src = "images/promo.jpg"
</script>
</head>
<body>
<p><img src="images/pentagg.jpg" width="500" height="300" name="slide" /></p>
<script type="text/javascript">
var step=1;
function slideit()
{
document.images.slide.src = eval("image"+step+".src");
if(step<2)
step++;
else
step=1;
setTimeout("slideit()",2500);
}
slideit();
</script>
</body>
playsinline
attribute in video tag like this:<video class="video-background" autoplay loop muted playsinline>
It only worked when including playsinline
.
Since the tests will be instantiated like a Spring bean too, you just need to implement the ApplicationContextAware interface:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/services-test-config.xml"})
public class MySericeTest implements ApplicationContextAware
{
@Autowired
MyService service;
...
@Override
public void setApplicationContext(ApplicationContext context)
throws BeansException
{
// Do something with the context here
}
}
You can use native function Date.toLocaleTimeString()
:
var d = new Date();
var n = d.toLocaleTimeString();
This will display e.g.:
"11:33:01"
I found it on http://www.w3schools.com/jsref/jsref_tolocaletimestring.asp
var d = new Date();_x000D_
var n = d.toLocaleTimeString();_x000D_
alert("The time is: \n"+n);
_x000D_
Shorter and dealing with a column (entire, not just a section of a column):
=COUNTA(A:A)
Beware, a cell containing just a space would be included in the count.

ndk-build
if you have a jni
directory in your project sources.This is working on Android studio 0.5.9 (canary build).
Either add ANDROID_NDK_HOME
to your environment variables or add ndk.dir=/path/to/ndk
to your local.properties
in your Android Studio project. This allows Android studio to run the ndk automatically.
Download the latest gradle sample projects to see an example of an ndk project. (They're at the bottom of the page). A good sample project is ndkJniLib
.
Copy the gradle.build
from the NDK sample projects. It'll look something like this. This gradle.build
creates a different apk for each architecture. You must select which architecture you want using the build variants
pane.
apply plugin: 'android'
dependencies {
compile project(':lib')
}
android {
compileSdkVersion 19
buildToolsVersion "19.0.2"
// This actual the app version code. Giving ourselves 100,000 values [0, 99999]
defaultConfig.versionCode = 123
flavorDimensions "api", "abi"
productFlavors {
gingerbread {
flavorDimension "api"
minSdkVersion 10
versionCode = 1
}
icecreamSandwich {
flavorDimension "api"
minSdkVersion 14
versionCode = 2
}
x86 {
flavorDimension "abi"
ndk {
abiFilter "x86"
}
// this is the flavor part of the version code.
// It must be higher than the arm one for devices supporting
// both, as x86 is preferred.
versionCode = 3
}
arm {
flavorDimension "abi"
ndk {
abiFilter "armeabi-v7a"
}
versionCode = 2
}
mips {
flavorDimension "abi"
ndk {
abiFilter "mips"
}
versionCode = 1
}
fat {
flavorDimension "abi"
// fat binary, lowest version code to be
// the last option
versionCode = 0
}
}
// make per-variant version code
applicationVariants.all { variant ->
// get the version code of each flavor
def apiVersion = variant.productFlavors.get(0).versionCode
def abiVersion = variant.productFlavors.get(1).versionCode
// set the composite code
variant.mergedFlavor.versionCode = apiVersion * 1000000 + abiVersion * 100000 + defaultConfig.versionCode
}
}
Note that this will ignore your Android.mk and Application.mk files. As a workaround, you can tell gradle to disable atuomatic ndk-build call, then specify the directory for ndk sources manually.
sourceSets.main {
jniLibs.srcDir 'src/main/libs' // use the jni .so compiled from the manual ndk-build command
jni.srcDirs = [] //disable automatic ndk-build call
}
In addition, you'll probably want to call ndk-build in your gradle build script explicitly, because you just disabled the automatic call.
task ndkBuild(type: Exec) {
commandLine 'ndk-build', '-C', file('src/main/jni').absolutePath
}
tasks.withType(JavaCompile) {
compileTask -> compileTask.dependsOn ndkBuild
}
This worked for me to add an array within an array
this.setState(prevState => ({
component: prevState.component.concat(new Array(['new', 'new']))
}));
You can change the Font Awesome's icon color with the bootstrap class
use
text-color
example
text-white
1-liner, takes a XML string text
and YourType
as the expected object type. not very different from other answers, just compressed to 1 line:
var result = (YourType)new XmlSerializer(typeof(YourType)).Deserialize(new StringReader(text));
Unless you're worried about performance, use string streams:
#include <sstream>
//..
std::ostringstream ss;
ss << myFloat;
std::string s(ss.str());
If you're okay with Boost, lexical_cast<> is a convenient alternative:
std::string s = boost::lexical_cast<std::string>(myFloat);
Efficient alternatives are e.g. FastFormat or simply the C-style functions.
The Java virtual machine is organized into three generations: a young generation, an old generation, and a permanent generation. Most objects are initially allocated in the young generation. The old generation contains objects that have survived some number of young generation collections, as well as some large objects that may be allocated directly in the old generation. The permanent generation holds objects that the JVM finds convenient to have the garbage collector manage, such as objects describing classes and methods, as well as the classes and methods themselves.
try
.something {
background: url(images/bg.jpg) no-repeat center center fixed;
width: 100%;
height: 100%;
position: fixed;
top: 0;
left: 0;
z-index: -100;
}
Here are three ways you can check if dict is empty. I prefer using the first way only though. The other two ways are way too wordy.
test_dict = {}
if not test_dict:
print "Dict is Empty"
if not bool(test_dict):
print "Dict is Empty"
if len(test_dict) == 0:
print "Dict is Empty"
Use the which function:
A <- c('a','a','b','b','b')
B <- c(1,0,1,1,0)
d <- data.frame(A, B)
r <- with(d, which(B==0, arr.ind=TRUE))
newd <- d[-r, ]
In python 2.7, the /
operator is integer division if inputs are integers.
If you want float division (which is something I always prefer), just use this special import:
from __future__ import division
See it here:
>>> 7 / 2
3
>>> from __future__ import division
>>> 7 / 2
3.5
>>>
Integer division is achieved by using //
, and modulo by using %
>>> 7 % 2
1
>>> 7 // 2
3
>>>
EDIT
As commented by user2357112
, this import has to be done before any other normal import.
(In reply to the "has the situation improved?" part of the question):
Unfortunately, not really. Illustrator's support for SVG has always been a little shaky, and, having mucked around in Illustrator's internals, I doubt we'll see much improvement as far as Illustrator is concerned.
If you're looking for DOM-style access to an Illustrator document, you might want to check out Hanpuku (Disclosure #1: I'm the author. Disclosure #2: It's research code, meaning there are bugs aplenty, and future support is unlikely).
With Hanpuku, you could do something like:
In the script editor, type:
selection.attr('d', 'M 0 0 L 20 134 L 233 24 Z');
Click run
Granted, this approach doesn't expose the original path string. If you follow the instructions toward the end of the plugin's welcome page, it's possible to edit the Illustrator document with Chrome's developer tools, but there will be lots of ugly engineering exposed everywhere (the SVG DOM that mirrors the Illustrator document is buried inside an iframe deep in the extension—changing the DOM with Chrome's tools and clicking "To Illustrator" should still work, but you will likely encounter lots of problems).
TL;DR: Illustrator uses an internal model that's pretty different from SVG in a lot of ways, meaning that when you iterate between the two, currently, your only choice is to use the subset of features that both support in the same way.
If downgrading from pip version 10 because of PyCharm manage.py or other python errors:

It's printing out a number every time it finds one that is higher than the current max (which happens to occur three times in your case.) Move the print outside of the for loop and you should be good.
for (int counter = 1; counter < decMax.length; counter++)
{
if (decMax[counter] > max)
{
max = decMax[counter];
}
}
System.out.println("The highest maximum for the December is: " + max);
Here's a solution for find/replace in all files of a given directory. Basically I took the answer provided by sepp2k and expanded it.
# First set the files to search/replace in
files = Dir.glob("/PATH/*")
# Then set the variables for find/replace
@original_string_or_regex = /REGEX/
@replacement_string = "STRING"
files.each do |file_name|
text = File.read(file_name)
replace = text.gsub!(@original_string_or_regex, @replacement_string)
File.open(file_name, "w") { |file| file.puts replace }
end
I had the same issue, I am using Plesk Onyx 17 with Centos7. I could see this error in proxy_error_log under the affected domain's logs. All the dirs/files in /var/www/vhosts/ are owned by respective users (domain owners) and you can see that all of them are in psacln group. So solution was to add nginx also to this group, so he can see what he needs:
usermod -aG psacln nginx
And indeed, restart nginx and reload page with Ctrl+F5.
Using array_column to re-index will save time if you need to find multiple times:
$lookup = array_column($arr, NULL, 'id'); // re-index by 'id'
Then you can simply $lookup[$id]
at will.
I saw this problem today when trying to create a WCF service proxy, both using VS2010 and svcutil.
Everything I'm doing is with basicHttpBinding
(so no issue with wsHttpBinding
).
For the first time in my recollection MSDN actually provided me with the solution, at the following link How to: Publish Metadata for a Service Using a Configuration File. The line I needed to change was inside the behavior element inside the MEX service behavior element inside my service app.config file. I changed it from
<serviceMetadata httpGetEnabled="true"/>
to
<serviceMetadata httpGetEnabled="true" policyVersion="Policy15"/>
and like magic the error went away and I was able to create the service proxy. Note that there is a corresponding MSDN entry for using code instead of a config file: How to: Publish Metadata for a Service Using Code.
(Of course, Policy15 - how could I possibly have overlooked that???)
One more "gotcha": my service needs to expose 3 different endpoints, each supporting a different contract. For each proxy that I needed to build, I had to comment out the other 2 endpoints, otherwise svcutil would complain that it could not resolve the base URL address.

Are you not seeing them from the browser, or on the server? Try the browser tooling or a debug proxy and see what is being sent out.
If you're willing to transmit some data and that you don't need to be secured (any public infos) you can use a CORS proxy, it's very easy, you'll not have to change anything in your code or in server side (especially of it's not your server like the Yahoo API or OpenWeather). I've used it to fetch JSON files with an XMLHttpRequest and it worked fine.
Now in rails 5 yu can do:
rails restart
This print by rails --tasks
Restart app by touching tmp/restart.txt
I think that is usefully if you run rails as a demon
You need to create own PCH file
Add New file -> Other-> PCH file
Then add the path of this PCH file to your build setting->prefix header->path
($(SRCROOT)/filename.pch)
If you have to install an older version of a package, just specify it
npm install <package>@<version>
For example: npm install [email protected]
You can also add the --save
flag to that command to add it to your package.json dependencies, or --save --save-exact
flags if you want that exact version specified in your package.json dependencies.
The install
command is documented here: https://docs.npmjs.com/cli/install
If you're not sure what versions of a package are available, you can use:
npm view <package> versions
And npm view
can be used for viewing other things about a package too. https://docs.npmjs.com/cli/view

I had the same problem with ALTER TABLE ADD FOREIGN KEY
.
After an hour, I found that these conditions must be satisfied to not get error 150:
The Parent table must exist before you define a foreign key to reference it. You must define the tables in the right order: Parent table first, then the Child table. If both tables references each other, you must create one table without FK constraints, then create the second table, then add the FK constraint to the first table with ALTER TABLE
.
The two tables must both support foreign key constraints, i.e. ENGINE=InnoDB
. Other storage engines silently ignore foreign key definitions, so they return no error or warning, but the FK constraint is not saved.
The referenced columns in the Parent table must be the left-most columns of a key. Best if the key in the Parent is PRIMARY KEY
or UNIQUE KEY
.
The FK definition must reference the PK column(s) in the same order as the PK definition. For example, if the FK REFERENCES Parent(a,b,c)
then the Parent's PK must not be defined on columns in order (a,c,b)
.
The PK column(s) in the Parent table must be the same data type as the FK column(s) in the Child table. For example, if a PK column in the Parent table is UNSIGNED
, be sure to define UNSIGNED
for the corresponding column in the Child table field.
Exception: length of strings may be different. For example, VARCHAR(10)
can reference VARCHAR(20)
or vice versa.
Any string-type FK column(s) must have the same character set and collation as the corresponding PK column(s).
If there is data already in the Child table, every value in the FK column(s) must match a value in the Parent table PK column(s). Check this with a query like:
SELECT COUNT(*) FROM Child LEFT OUTER JOIN Parent ON Child.FK = Parent.PK
WHERE Parent.PK IS NULL;
This must return zero (0) unmatched values. Obviously, this query is an generic example; you must substitute your table names and column names.
Neither the Parent table nor the Child table can be a TEMPORARY
table.
Neither the Parent table nor the Child table can be a PARTITIONED
table.
If you declare a FK with the ON DELETE SET NULL
option, then the FK column(s) must be nullable.
If you declare a constraint name for a foreign key, the constraint name must be unique in the whole schema, not only in the table in which the constraint is defined. Two tables may not have their own constraint with the same name.
If there are any other FK's in other tables pointing at the same field you are attempting to create the new FK for, and they are malformed (i.e. different collation), they will need to be made consistent first. This may be a result of past changes where SET FOREIGN_KEY_CHECKS = 0;
was utilized with an inconsistent relationship defined by mistake. See @andrewdotn's answer below for instructions on how to identify these problem FK's.
Hope this helps.

Case in method names is important, so no addclass

You need to give the user table an alias the second time you join to it
e.g.
SELECT article . * , section.title, category.title, user.name, u2.name
FROM article
INNER JOIN section ON article.section_id = section.id
INNER JOIN category ON article.category_id = category.id
INNER JOIN user ON article.author_id = user.id
LEFT JOIN user u2 ON article.modified_by = u2.id
WHERE article.id = '1'
In case you are using WinPython and not anaconda then you need to navigate to the directory where you installed the WinPython for e.g. C:\WPy-3670\settings\.jupyter\jupyter_notebook_config.py
You need to edit this file and find the line
#c.NotebookApp.notebook_dir = ''
change it to for e.g.
c.NotebookApp.notebook_dir = 'D:/your_own_folder/containing/jupyter_notes'
You also need to change backslash \
to forward slashes /
. also make sure to uncomment the line by removing #
You can't implicitly return with an if
, you would need the braces:
let adults = family.filter(person => { if (person.age > 18) return person} );
It can be simplified though:
let adults = family.filter(person => person.age > 18);
Following code will do the task....
<?php
$contacts = array(
"[email protected]",
"[email protected]",
//....as many email address as you need
);
foreach($contacts as $contact) {
$to = $contact;
$subject = 'the subject';
$message = 'hello';
mail($to, $subject, $message, $headers);
}
?>
Rookie, if you want to write a file to server by socket, how about using fileoutputstream instead of dataoutputstream? dataoutputstream is more fit for protocol-level read-write. it is not very reasonable for your code in bytes reading and writing. loop to read and write is necessary in java io. and also, you use a buffer way. flush is necessary. here is a code sample: http://www.rgagnon.com/javadetails/java-0542.html
getline(fin, buffer, '\n')
where fin
is opened file(ifstream object) and buffer
is of string/char
type where you want to copy line.
var number = 3200;
var hexString = number.toString(16);
The 16 is the radix and there are 16 values in a hexadecimal number :-)
It should be
Intent myIntent = new Intent(this, Katra_home.class);
startActivity(myIntent);
You have to use existing activity context to start new activity, new activity is not created yet, and you cannot use its context or call methods upon it.
not an enclosing class error is thrown because of your usage of this
keyword. this
is a reference to the current object — the object whose method or constructor is being called. With this
you can only refer to any member of the current object from within an instance method or a constructor.
Katra_home.this
is invalid construct
If you like 'Mike Sherrill' solution but don't want to use psql, I used this query to get the missing information:
select column_name,
case
when domain_name is not null then domain_name
when data_type='character varying' THEN 'varchar('||character_maximum_length||')'
when data_type='numeric' THEN 'numeric('||numeric_precision||','||numeric_scale||')'
else data_type
end as myType
from information_schema.columns
where table_name='test'
with result:
column_name | myType
-------------+-------------------
test_id | test_domain
test_vc | varchar(15)
test_n | numeric(15,3)
big_n | bigint
ip_addr | inet

Permissions that Imply Feature Requirements
example, the android.hardware.bluetooth feature was added in Android 2.2 (API level 8), but the bluetooth API that it refers to was added in Android 2.0 (API level 5). Because of this, some apps were able to use the API before they had the ability to declare that they require the API via the system.
To prevent those apps from being made available unintentionally, Google Play assumes that certain hardware-related permissions indicate that the underlying hardware features are required by default. For instance, applications that use Bluetooth must request the BLUETOOTH permission in a element — for legacy apps, Google Play assumes that the permission declaration means that the underlying android.hardware.bluetooth feature is required by the application and sets up filtering based on that feature.
The table below lists permissions that imply feature requirements equivalent to those declared in elements. Note that declarations, including any declared android:required attribute, always take precedence over features implied by the permissions below.
For any of the permissions below, you can disable filtering based on the implied feature by explicitly declaring the implied feature explicitly, in a element, with an android:required="false" attribute. For example, to disable any filtering based on the CAMERA permission, you would add this declaration to the manifest file:
<uses-feature android:name="android.hardware.camera" android:required="false" />
<uses-feature android:name="android.hardware.bluetooth" android:required="false" />
<uses-feature android:name="android.hardware.location" android:required="false" />
<uses-feature android:name="android.hardware.location.gps" android:required="false" />
<uses-feature android:name="android.hardware.telephony" android:required="false" />
<uses-feature android:name="android.hardware.wifi" android:required="false" />
http://developer.android.com/guide/topics/manifest/uses-feature-element.html#permissions
I was going to leave this after this comment: Should I check in folder "node_modules" to Git when creating a Node.js app on Heroku?
But Stack Overflow was formatting it weirdly.
If you don't have identical machines and are checking in node_modules, do a .gitignore on the native extensions. Our .gitignore looks like:
# Ignore native extensions in the node_modules folder (things changed by npm rebuild)
node_modules/**/*.node
node_modules/**/*.o
node_modules/**/*.a
node_modules/**/*.mk
node_modules/**/*.gypi
node_modules/**/*.target
node_modules/**/.deps/
node_modules/**/build/Makefile
node_modules/**/**/build/Makefile
Test this by first checking everything in, and then have another developer do the following:
rm -rf node_modules
git checkout -- node_modules
npm rebuild
git status
Ensure that no files changed.
Your query is close you need to join using the mgr
and the empid
on e1.mgr = e2.empid
So the full query is:
select e1.ename Emp,
e2.eName Mgr
from employees e1
inner join employees e2
on e1.mgr = e2.empid
If you want to return all rows including those without a manager then you would change it to a LEFT JOIN
(for example the president):
select e1.ename Emp,
e2.eName Mgr
from employees e1
left join employees e2
on e1.mgr = e2.empid
The president in your sample data will return a null
value for the manager because they do not have a manager.
They provide the capability to extend existing types by adding new methods with no modifications necessary to the type. Calling methods from objects of the extended type within an application using instance method syntax is known as ‘‘extending’’ methods. Extension methods are not instance members on the type. The key point to remember is that extension methods, defined as static methods, are in scope only when the namespace is explicitly imported into your application source code via the using directive. Even though extension methods are defined as static methods, they are still called using instance syntax.
Check the full example here http://www.dotnetreaders.com/articles/Extension_methods_in_C-sharp.net,Methods_in_C_-sharp/201
Example:
class Extension
{
static void Main(string[] args)
{
string s = "sudhakar";
Console.WriteLine(s.GetWordCount());
Console.ReadLine();
}
}
public static class MyMathExtension
{
public static int GetWordCount(this System.String mystring)
{
return mystring.Length;
}
}
The syntaxes
int[]
and
int[X] // Where X is a compile-time positive integer
are exactly the same as
int*
when in a function parameter list (I left out the optional names).
Additionally, an array name decays to a pointer to the first element when passed to a function (and not passed by reference) so both int firstarray[3]
and int secondarray[5]
decay to int*
s.
It also happens that both an array dereference and a pointer dereference with subscript syntax (subscript syntax is x[y]
) yield an lvalue to the same element when you use the same index.
These three rules combine to make the code legal and work how you expect; it just passes pointers to the function, along with the length of the arrays which you cannot know after the arrays decay to pointers.
Apparently the only reliable and accepted solution would be to do feature detection like this:
browser_treats_urls_like_safari_does = false;
var last_location_hash = location.hash;
location.hash = '"blah"';
if (location.hash == '#%22blah%22')
browser_treats_urls_like_safari_does = true;
location.hash = last_location_hash;
To write in the Visual Studio output window I used IVsOutputWindow
and IVsOutputWindowPane
. I included as members in my OutputWindow
class which look like this :
public class OutputWindow : TextWriter
{
#region Members
private static readonly Guid mPaneGuid = new Guid("AB9F45E4-2001-4197-BAF5-4B165222AF29");
private static IVsOutputWindow mOutputWindow = null;
private static IVsOutputWindowPane mOutputPane = null;
#endregion
#region Constructor
public OutputWindow(DTE2 aDte)
{
if( null == mOutputWindow )
{
IServiceProvider serviceProvider =
new ServiceProvider(aDte as Microsoft.VisualStudio.OLE.Interop.IServiceProvider);
mOutputWindow = serviceProvider.GetService(typeof(SVsOutputWindow)) as IVsOutputWindow;
}
if (null == mOutputPane)
{
Guid generalPaneGuid = mPaneGuid;
mOutputWindow.GetPane(ref generalPaneGuid, out IVsOutputWindowPane pane);
if ( null == pane)
{
mOutputWindow.CreatePane(ref generalPaneGuid, "Your output window name", 0, 1);
mOutputWindow.GetPane(ref generalPaneGuid, out pane);
}
mOutputPane = pane;
}
}
#endregion
#region Properties
public override Encoding Encoding => System.Text.Encoding.Default;
#endregion
#region Public Methods
public override void Write(string aMessage) => mOutputPane.OutputString($"{aMessage}\n");
public override void Write(char aCharacter) => mOutputPane.OutputString(aCharacter.ToString());
public void Show(DTE2 aDte)
{
mOutputPane.Activate();
aDte.ExecuteCommand("View.Output", string.Empty);
}
public void Clear() => mOutputPane.Clear();
#endregion
}
If you have a big text to write in output window you usually don't want to freeze the UI. In this purpose you can use a Dispatcher
. To write something in output window using this implementation now you can simple do this:
Dispatcher mDispatcher = HwndSource.FromHwnd((IntPtr)mDte.MainWindow.HWnd).RootVisual.Dispatcher;
using (OutputWindow outputWindow = new OutputWindow(mDte))
{
mDispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(() =>
{
outputWindow.Write("Write what you want here");
}));
}
If you use custom Makefiles, you can double click on the .includes file and add it there.
I found my answer here:
edit ~/.gitconfig
and add the following:
[url "[email protected]:"]
insteadOf = https://github.com/
Although it solves a different problem, the error code is the same...
I like to disable the button and call a postback, this way the code behind still gets run after the button is disabled.
this is how i attach from code behind:
btnProcess.Attributes.Add("onclick", " this.disabled = true; __doPostBack('btnProcess', ''); return false;")
Then re-enable the button in code behind:
btnProcess.Enabled = True
Can you try a custom CSS aside the bootstrap CSS to see if any changes. Try
.move-rigth{
display: block;
float: right;
}
If it works then you can try manipulating what you have or adding other formatting to this and achieving what you desire. Because you are using bootstrap doesn't mean if it doesn't offer you what you want then you just manage it. You are working with your codes and so you command it to do as you say. Cheers!
Slightly different approach:
bool A() {...}
bool B() {...}
bool C() {...}
int main(void)
{
/**
* Declare an array of pointers to functions returning bool
* and initialize with A, B, and C
*/
bool (*farr[])() = {A, B, C};
...
/**
* Call A, B, or C based on the value of i
* (assumes i is in range of array)
*/
if (farr[i]()) // or (*farr[i])()
{
...
}
...
}
git reset --hard 1258f0d0aae
But be careful, if the descendant commits between 1258f0d0aae
and HEAD
are not referenced in other branches it'll be tedious (but not impossible) to recover them, so you'd better to create a "backup" branch at current HEAD
, checkout master
, and reset to the commit you want.
Also, be sure that you don't have uncommitted changes before a reset --hard
, they will be truly lost (no way to recover).
Use the WebClient
class in System.Net
:
var json = new WebClient().DownloadString("url");
Keep in mind that WebClient
is IDisposable
, so you would probably add a using
statement to this in production code. This would look like:
using (WebClient wc = new WebClient())
{
var json = wc.DownloadString("url");
}
In my situation, I created a new SSRS report and new stored procedure for the dataset. I forgot to add the stored procedure to the database role that had permission to execute it. Once I added the permissions to SQL database role with EXECUTE, all was fine!
The error message encountered by the user was "An error occurred during client rendering. An error has occurred during report processing (rsProcessingAborted). Query execution failed for dataset "DataSet1'. (rsErrorExecutingCommand) For more information..."
Ask Tom on pagination and very, very useful analytic functions.

No, IIRC there is no getopt() on Windows.
Boost, however, has the program_options library... which works okay. It will seem like overkill at first, but it isn't terrible, especially considering it can handle setting program options in configuration files and environment variables in addition to command line options.
public void Foo(IList<Bar> list)
{
// Do Something with the list here.
}
In this case you could pass in any class which implements the IList<Bar> interface. If you used List<Bar> instead, only a List<Bar> instance could be passed in.
The IList<Bar> way is more loosely coupled than the List<Bar> way.
Short answer: mathematically speaking, no, in practical terms, yes, for example for Intentional Programming.
Technically, the answer would be "no, it's not needed" because it's expressible using other constructs. But in practice, I use for i in range(len(a)
(or for _ in range(len(a))
if I don't need the index) to make it explicit that I want to iterate as many times as there are items in a sequence without needing to use the items in the sequence for anything.
So: "Is there a need?"? — yes, I need it to express the meaning/intent of the code for readability purposes.
See also: https://en.wikipedia.org/wiki/Intentional_programming
And obviously, if there is no collection that is associated with the iteration at all, for ... in range(len(N))
is the only option, so as to not resort to i = 0; while i < N; i += 1 ...
My opinion after making changes on your .env files restart your server and serve the app again. Just to be sure of the actual error. The php artisan clear and cache afterwards works pretty fine.
Have you already looked at adding a check constraint
on that column which would restrict values? Something like:
CREATE TABLE SomeTable
(
Id int NOT NULL,
Frequency varchar(200),
CONSTRAINT chk_Frequency CHECK (Frequency IN ('Daily', 'Weekly', 'Monthly', 'Yearly'))
)
Connect to port 80 on the host and send it
HEAD / HTTP/1.0
This needs to be followed by carriage-return + line-feed twice
You'll get back something like this
HTTP/1.1 200 OK

Server: Apache/2.2.9 (Ubuntu) DAV/2 SVN/1.5.0 PHP/5.2.6-1ubuntu4 with Suhosin-Patch mod_perl/2.0.4 Perl/v5.10.0

You can then extract the apache version from the Server: header
You could use the HEAD utility which comes with a full install of Perl's LWP library, e.g.
HEAD http://your.webserver.com/
Or, use the curl utility, e.g.
curl --head http://your.webserver.com/
You could also use a browser extension which lets you view server headers, such as Live HTTP Headers or Firebug for Firefox, or Fiddler for IE
Finally. if you're on Windows, and have nothing else at your disposal, open a command prompt (Start Menu->Run, type "cmd" and press return), and then type this
telnet your.webserver.com 80
Then type (carefully, your characters won't be echoed back)
HEAD / HTTP/1.0
Press return twice and you'll see the server headers.
As mentioned by cfeduke and Veynom, the server may be set to return limited information in the Server: header. Try and upload a PHP script to your host with this in it
<?php phpinfo() ?>
Request the page with a web browser and you should see the Apache version reported there.
You could also try and use PHPShell to have a poke around, try a command like
/usr/sbin/apache2 -V
You can also try using multiprocessing.Process
with daemon=True
; the process.start()
method does not block and you can return a response/status immediately to the caller while your expensive function executes in the background.
I experienced similar problem while working with falcon framework and using daemon
process helped.
You'd need to do the following:
from multiprocessing import Process
@app.route('/render/<id>', methods=['POST'])
def render_script(id=None):
...
heavy_process = Process( # Create a daemonic process with heavy "my_func"
target=my_func,
daemon=True
)
heavy_process.start()
return Response(
mimetype='application/json',
status=200
)
# Define some heavy function
def my_func():
time.sleep(10)
print("Process finished")
You should get a response immediately and, after 10s you should see a printed message in the console.
NOTE: Keep in mind that daemonic
processes are not allowed to spawn any child processes.
By the way, in C# 3.5 you can instantiate your object's properties like so:
Person TOM=new Person
{
title = "My title", ID = 1
};
But again, properties must be public.
It is just a typo(I guess)-
p+=1;
instead of p +1=p;
is required .
As name suggest lvalue
expression should be left-hand operand of the assignment operator.
I tried the first error and that didn't help me. However What did work for me was to delete the hidden ".vs" folder which is at the solution root.
I encounter the same problem, and @Joe Kington and @bvanlew's answer solve my problem.
but I should add more infomation when you use pycharm and enable auto import
.
when you format the code, the code from mpl_toolkits.mplot3d import Axes3D
will auto remove by pycharm.
so, my solution is
from mpl_toolkits.mplot3d import Axes3D
Axes3D = Axes3D # pycharm auto import
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
and it works well!
You can use moment js for this purpose. momentJs 'fromNow()' will give you any time difference from current time.

The keypress event from jQuery is meant to do this sort of work. You can trigger the event by passing a string "keypress" to .trigger(). However to be more specific you can actually pass a jQuery.Event object (specify the type as "keypress") as well and provide any properties you want such as the keycode being the spacebar.

You need add parameter errors='coerce'
to function to_numeric
:
ID = pd.to_numeric(ID, errors='coerce')
If ID
is column:
df.ID = pd.to_numeric(df.ID, errors='coerce')
but non numeric are converted to NaN
, so all values are float
.
For int
need convert NaN
to some value e.g. 0
and then cast to int
:
df.ID = pd.to_numeric(df.ID, errors='coerce').fillna(0).astype(np.int64)
Sample:
df = pd.DataFrame({'ID':['4806105017087','4806105017087','CN414149']})
print (df)
ID
0 4806105017087
1 4806105017087
2 CN414149
print (pd.to_numeric(df.ID, errors='coerce'))
0 4.806105e+12
1 4.806105e+12
2 NaN
Name: ID, dtype: float64
df.ID = pd.to_numeric(df.ID, errors='coerce').fillna(0).astype(np.int64)
print (df)
ID
0 4806105017087
1 4806105017087
2 0
EDIT: If use pandas 0.25+ then is possible use integer_na
:
df.ID = pd.to_numeric(df.ID, errors='coerce').astype('Int64')
print (df)
ID
0 4806105017087
1 4806105017087
2 NaN
Here is a snippet that gets the default newline character for the current platform.
Use
System.getProperty("os.name")
and
System.getProperty("os.version").
Example:
public static String getSystemNewline(){
String eol = null;
String os = System.getProperty("os.name").toLowerCase();
if(os.contains("mac"){
int v = Integer.parseInt(System.getProperty("os.version"));
eol = (v <= 9 ? "\r" : "\n");
}
if(os.contains("nix"))
eol = "\n";
if(os.contains("win"))
eol = "\r\n";
return eol;
}
Where eol is the newline
There are many articles about writing code to import an excel file, but this is a manual/shortcut version:
If you don't need to import your Excel file programmatically using code you can do it very quickly using the menu in SQL Management Studio.
The quickest way to get your Excel file into SQL is by using the import wizard:
The next window is 'Choose a Data Source', select Excel:
In the 'Data Source' dropdown list select Microsoft Excel (this option should appear automatically if you have excel installed).
Click the 'Browse' button to select the path to the Excel file you want to import.
On the 'Specify Table Copy or Query' window:
'Select Source Tables:' choose the worksheet(s) from your Excel file and specify a destination table for each worksheet. If you don't have a table yet the wizard will very kindly create a new table that matches all the columns from your spreadsheet. Click Next.
dplyr
version 1.0.0
includes the relocate()
function to easily reorder columns:
dat <- data.frame(Time=c(1,2), In=c(2,3), Out=c(3,4), Files=c(4,5))
library(dplyr) # from version 1.0.0 only
dat %>%
relocate(Out, .before = In)
or
dat %>%
relocate(Out, .after = Time)
Does '%' mean either "mod" or "rem" in C?
In C, %
is the remainder1.
..., the result of the
/
operator is the algebraic quotient with any fractional part discarded ... (This is often called "truncation toward zero".) C11dr §6.5.5 6The operands of the
%
operator shall have integer type. C11dr §6.5.5 2The result of the
/
operator is the quotient from the division of the first operand by the second; the result of the%
operator is the remainder ... C11dr §6.5.5 5
What's the difference between “mod” and “remainder”?
C does not define "mod", such as the integer modulus function used in Euclidean division or other modulo. "Euclidean mod" differs from C's a%b
operation when a
is negative.
// a % b
7 % 3 --> 1
7 % -3 --> 1
-7 % 3 --> -1
-7 % -3 --> -1
Modulo as Euclidean division
7 modulo 3 --> 1
7 modulo -3 --> 1
-7 modulo 3 --> 2
-7 modulo -3 --> 2
Candidate modulo code:
int modulo_Euclidean(int a, int b) {
int m = a % b;
if (m < 0) {
// m += (b < 0) ? -b : b; // avoid this form: it is UB when b == INT_MIN
m = (b < 0) ? m - b : m + b;
}
return m;
}
Note about floating point: double fmod(double x, double y)
, even though called "fmod", it is not the same as Euclidean division "mod", but similar to C integer remainder:
The
fmod
functions compute the floating-point remainder ofx/y
. C11dr §7.12.10.1 2
fmod( 7, 3) --> 1.0
fmod( 7, -3) --> 1.0
fmod(-7, 3) --> -1.0
fmod(-7, -3) --> -1.0
Disambiguation: C also has a similar named function double modf(double value, double *iptr)
which breaks the argument value into integral and fractional parts, each of which has the same type and sign as the argument. This has little to do with the "mod" discussion here except name similarity.
[Edit Dec 2020]
For those who want proper functionality in all cases, an improved modulo_Euclidean()
that 1) detects mod(x,0)
and 2) a good and no UB result with modulo_Euclidean2(INT_MIN, -1)
. Inspired by 4 different implementations of modulo with fully defined behavior.
int modulo_Euclidean2(int a, int b) {
if (b == 0) TBD_Code(); // perhaps return -1 to indicate failure?
if (b == -1) return 0; // This test needed to prevent UB of `INT_MIN % -1`.
int m = a % b;
if (m < 0) {
// m += (b < 0) ? -b : b; // avoid this form: it is UB when b == INT_MIN
m = (b < 0) ? m - b : m + b;
}
return m;
}
1 Prior to C99, C's definition of %
was still the remainder from division, yet then /
allowed negative quotients to round down rather than "truncation toward zero". See Why do you get different values for integer division in C89?. Thus with some pre-C99 compilation, %
code can act just like the Euclidean division "mod". The above modulo_Euclidean()
will work with this alternate old-school remainder too.
For Spring Boot 2 if you don't want to use global CORS configuration, you can do it by method or class/controller level using @CrossOrigin
adnotation with exposedHeaders
atribute.
For example, to add header authorization
for YourController
methods:
@CrossOrigin(exposedHeaders = "authorization")
@RestController
public class YourController {
...
}
Having call
helps. However today it didn't.
This is how I solved it:
Bat file contents (if you want to stop batch when one of cmds errors)
cmd1 && ^
cmd2 && ^
cmd3 && ^
cmd4
Bat file contents (if you want to continue batch when one of cmds errors)
cmd1 & ^
cmd2 & ^
cmd3 & ^
cmd4
If you trust the data source, you can use eval
to convert your string into a dictionary:
eval(your_json_format_string)
Example:
>>> x = "{'a' : 1, 'b' : True, 'c' : 'C'}"
>>> y = eval(x)
>>> print x
{'a' : 1, 'b' : True, 'c' : 'C'}
>>> print y
{'a': 1, 'c': 'C', 'b': True}
>>> print type(x), type(y)
<type 'str'> <type 'dict'>
>>> print y['a'], type(y['a'])
1 <type 'int'>
>>> print y['a'], type(y['b'])
1 <type 'bool'>
>>> print y['a'], type(y['c'])
1 <type 'str'>
You can use the CSS3 Linear Gradient property along with your background-image like this:
#landing-wrapper {
display:table;
width:100%;
background: linear-gradient( rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5) ), url('landingpagepic.jpg');
background-position:center top;
height:350px;
}
Here's a demo:
#landing-wrapper {_x000D_
display: table;_x000D_
width: 100%;_x000D_
background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url('http://placehold.it/350x150');_x000D_
background-position: center top;_x000D_
height: 350px;_x000D_
color: white;_x000D_
}
_x000D_
<div id="landing-wrapper">Lorem ipsum dolor ismet.</div>
_x000D_
The findstr
command sets the ErrorLevel
(or exit code) to one of the following values, given that there are no invalid or incompatible switches and no search string exceeds the applicable length limit:
0
when at least a single match is encountered in one line throughout all specified files;1
otherwise;A line is considered to contain a match when:
/V
option is given and the search expression occurs at least once;/V
option is given and the search expression does not occur;This means that the /V
option also changes the returned ErrorLevel
, but it does not just revert it!
For example, when you have got a file test.txt
with two lines, one of which contains the string text
but the other one does not, both findstr "text" "test.txt"
and findstr /V "text" "test.txt"
return an ErrorLevel
of 0
.
Basically you can say: if findstr
returns at least a line, ErrorLevel
is set to 0
, else to 1
.
Note that the /M
option does not affect the ErrorLevel
value, it just alters the output.
(Just for the sake of completeness: the find
command behaves exactly the same way with respect to the /V
option and ErrorLevel
; the /C
option does not affect ErrorLevel
.)
This error can appear even if you load your script after the html render is finished. In this given example your code
<div id="hello"></div>
has no value inside the div. So the error is raised, because there is no value to change inside. It should have been
<div id="hello">Some random text to change</div>
then.
As an alternative to reading a data from a stream to a byte array, you could let the framework handle everything and just use a StreamReader
set up with an ASCII encoding to read in the string. That way you don't need to worry about getting the appropriate buffer size or larger data sizes.
using (var reader = new StreamReader(stream, Encoding.ASCII))
{
string theString = reader.ReadToEnd();
// do something with theString
}
You would use the command Mechanical snail listed. Notice the uppercase O. Full command line to use could be:
wget www.examplesite.com/textfile.txt --output-document=newfile.txt
or
wget www.examplesite.com/textfile.txt -O newfile.txt
Hope that helps.
String.Format must start with zero index "{0}" like this:
Aboutme.Text = String.Format("{0}", reader.GetString(0));
Open taskHistory.bin
and search for storePassword
It is generally not a bad idea to avoid the !-operator if you have the choice. One simple reason is that it can be a source of errors, because it is possible to overlook it. More readable can be: if(conditionA==false) in some cases. This mainly plays a role if you skip the else part. If you have an else-block anyway you should not use the negation in the if-condition.
Except for composed-conditions like this:
if(!isA() && isB() && !isNotC())
Here you have to use some sort of negation to get the desired logic. In this case, what really is worth thinking about is the naming of the functions or variables. Try to name them so you can often use them in simple conditions without negation.
In this case you should think about the logic of isNotC() and if it could be replaced by a method isC() if it makes sense.
Finally your example has another problem when it comes to readability which is even more serious than the question whether to use negation or not: Does the reader of the code really knows when doSomething() returns true and when false? If it was false was it done anyway? This is a very common problem, which ends in the reader trying to find out what the return values of functions really mean.
You can create an unsigned char:
unsigned char c = 0xc5;
Printing it will give C5
and not ffffffc5
.
Only the chars bigger than 127 are printed with the ffffff
because they are negative (char is signed).
Or you can cast the char
while printing:
char c = 0xc5;
printf("%x", (unsigned char)c);
You should use Asset Catalog:
I have investigated, how we can use Asset Catalog; Now it seems to be easy for me. I want to show you steps to add icons and splash in asset catalog.
Note: No need to make any entry in info.plist file :) And no any other configuration.
In below image, at right side, you will see highlighted area, where you can mention which icons you need. In case of mine, i have selected first four checkboxes; As its for my app requirements. You can select choices according to your requirements.
Now, see below image. As you will select any App icon then you will see its detail at right side selected area. It will help you to upload correct resolution icon.
If Correct resolution image will not be added then following warning will come. Just upload the image with correct resolution.
After uploading all required dimensions, you shouldn't get any warning.
Something like this might help (taken from a working app).
#include <memory>
#include <boost/asio.hpp>
#include <boost/thread.hpp>
struct thread_pool {
typedef std::unique_ptr<boost::asio::io_service::work> asio_worker;
thread_pool(int threads) :service(), service_worker(new asio_worker::element_type(service)) {
for (int i = 0; i < threads; ++i) {
auto worker = [this] { return service.run(); };
grp.add_thread(new boost::thread(worker));
}
}
template<class F>
void enqueue(F f) {
service.post(f);
}
~thread_pool() {
service_worker.reset();
grp.join_all();
service.stop();
}
private:
boost::asio::io_service service;
asio_worker service_worker;
boost::thread_group grp;
};
You can use it like this:
thread_pool pool(2);
pool.enqueue([] {
std::cout << "Hello from Task 1\n";
});
pool.enqueue([] {
std::cout << "Hello from Task 2\n";
});
Keep in mind that reinventing an efficient asynchronous queuing mechanism is not trivial.
Boost::asio::io_service is a very efficient implementation, or actually is a collection of platform-specific wrappers (e.g. it wraps I/O completion ports on Windows).
have you looked at layoutIfNeeded?
The documentation snippet is below. Does the animation work if you call this method explicitly during the animation?
layoutIfNeeded Lays out the subviews if needed.
- (void)layoutIfNeeded
Discussion Use this method to force the layout of subviews before drawing.
Availability Available in iPhone OS 2.0 and later.
From MSDN -
CollectionViewSource.GetDefaultView(myGrid.ItemsSource).Refresh();
Alternatively, you can do this from a Windows commandline prompt/batch file:
sqlite3.exe DB.db ".read db.sql"
Where DB.db is the database file, and db.sql is the SQL file to run/import.
As of Active Support and Rails 5.0.0.beta4 you can use one of both methods: String#upcase_first
or ActiveSupport::Inflector#upcase_first
.
"my API is great".upcase_first #=> "My API is great"
"?????".upcase_first #=> "?????"
"?????".upcase_first #=> "?????"
"NASA".upcase_first #=> "NASA"
"MHz".upcase_first #=> "MHz"
"sputnik".upcase_first #=> "Sputnik"

You can do it easily with grep:
grep -oE '[^ ]+$' file
(-E
use extended regex; -o
output only the matched text instead of the full line)
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />
serves two purposes.
IE=edge
: specifies that IE should run in the highest mode available to that version of IE as opposed to a compatability mode; IE8 can support up to IE8 modes, IE9 can support up to IE9 modes, and so on.chrome=1
: specifies that Google Chrome frame should start if the user has it installedThe IE=edge
flag is still relevant for IE versions 10 and below. IE11 sets this mode as the default.
As for the chrome flag, you can leave it if your users still use Chrome Frame. Despite support and updates for Chrome Frame ending, one can still install and use the final release. If you remove the flag, Chrome Frame will not be activated when installed. For other users, chrome=1
will do nothing more than consume a few bytes of bandwidth.
I recommend you analyze your audience and see if their browsers prohibit any needed features and then decide. Perhaps it might be better to encourage them to use a more modern, evergreen browser.
Note, the W3C validator will flag chrome=1
as an error:
Error: A meta element with an http-equiv attribute whose value is
X-UA-Compatible must have a content attribute with the value IE=edge.
Changing my header to the following solve the problem:
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
Use Str()
Function. It takes three arguments(the number, the number total characters to display, and the number of decimal places to display
Select Str(12345.6789, 12, 3)
displays: ' 12345.679' ( 3 spaces, 5 digits 12345, a decimal point, and three decimal digits (679). - it rounds if it has to truncate, (unless the integer part is too large for the total size, in which case asterisks are displayed instead.)
for a Total of 12 characters, with 3 to the right of decimal point.
Just as a note you can also use this for iPads:
activityViewController.popoverPresentationController?.sourceView = sender
So the popover pops from the sender (the button in that case).
Some quick but extremely useful additional information that I just learned from another post, but can't seem to find the documentation for (if anyone can share a link to it on MSDN that would be amazing):
The validation messages associated with these attributes will actually replace placeholders associated with the attributes. For example:
[MaxLength(100, "{0} can have a max of {1} characters")]
public string Address { get; set; }
Will output the following if it is over the character limit: "Address can have a max of 100 characters"
The placeholders I am aware of are:
Much thanks to bloudraak for initially pointing this out.

You should not be operating the state at all. At least, not directly. If you want to update your array, you'll want to do something like this.
var newStateArray = this.state.myArray.slice();
newStateArray.push('new value');
this.setState(myArray: newStateArray);
Working on the state object directly is not desirable. You can also take a look at React's immutability helpers.
If you are looking for 1st Number with decimal as string has correct decimal places, you may try regexp_substr
function like this:
regexp_substr('stack12.345overflow', '\.*[[:digit:]]+\.*[[:digit:]]*')
You might be able to do this with AutoGenerateColumns and a DataTemplate. I'm not positive if it would work without a lot of work, you would have to play around with it. Honestly if you have a working solution already I wouldn't make the change just yet unless there's a big reason. The DataGrid control is getting very good but it still needs some work (and I have a lot of learning left to do) to be able to do dynamic tasks like this easily.

The two protocols have very different uses in the real world.
SOAP(using WSDL) is a heavy-weight XML standard that is centered around document passing. The advantage with this is that your requests and responses can be very well structured, and can even use a DTD. The downside is it is XML, and is very verbose. However, this is good if two parties need to have a strict contract(say for inter-bank communication). SOAP also lets you layer things like WS-Security on your documents. SOAP is generally transport-agnostic, meaning you don't necessarily need to use HTTP.
REST is very lightweight, and relies upon the HTTP standard to do it's work. It is great to get a useful web service up and running quickly. If you don't need a strict API definition, this is the way to go. Most web services fall into this category. You can version your API so that updates to the API do not break it for people using old versions(as long as they specify a version). REST essentially requires HTTP, and is format-agnostic(meaning you can use XML, JSON, HTML, whatever).
Generally I use REST, because I don't need fancy WS-* features. SOAP is good though if you want computers to understand your webservice using a WSDL. REST specifications are generally human-readable only.

Different people who come to this question mean different things by a popup box. I highly recommend reading the Temporary Views documentation. My answer is largely a summary of this and other related documentation.
Alerts display a title and an optional message. The user must acknowledge it (a one-button alert) or make a simple choice (a two-button alert) before going on. You create an alert with a UIAlertController
.
It is worth quoting the documentation's warning and advice about creating unnecessary alerts.
Notes:
UIAlertView
was deprecated. You should use UIAlertController
to create alerts now.Action Sheets give the user a list of choices. They appear either at the bottom of the screen or in a popover depending on the size and orientation of the device. As with alerts, a UIAlertController
is used to make an action sheet. Before iOS 8, UIActionSheet
was used, but now the documentation says:
Important:
UIActionSheet
is deprecated in iOS 8. (Note thatUIActionSheetDelegate
is also deprecated.) To create and manage action sheets in iOS 8 and later, instead useUIAlertController
with apreferredStyle
ofUIAlertControllerStyleActionSheet
.
A modal view is a self-contained view that has everything it needs to complete a task. It may or may not take up the full screen. To create a modal view, use a UIPresentationController
with one of the Modal Presentation Styles.
See also
A Popover is a view that appears when a user taps on something and disappears when tapping off it. It has an arrow showing the control or location from where the tap was made. The content can be just about anything you can put in a View Controller. You make a popover with a UIPopoverPresentationController
. (Before iOS 8, UIPopoverController
was the recommended method.)
In the past popovers were only available on the iPad, but starting with iOS 8 you can also get them on an iPhone (see here, here, and here).

Notifications are sounds/vibrations, alerts/banners, or badges that notify the user of something even when the app is not running in the foreground.

In Android, a Toast is a short message that displays on the screen for a short amount of time and then disappears automatically without disrupting user interaction with the app.
People coming from an Android background want to know what the iOS version of a Toast is. Some examples of these questions can he found here, here, here, and here. The answer is that there is no equivalent to a Toast in iOS. Various workarounds that have been presented include:
UIView
However, my advice is to stick with the standard UI options that already come with iOS. Don't try to make your app look and behave exactly the same as the Android version. Think about how to repackage it so that it looks and feels like an iOS app.
// The below C++ function checks for a palindrome and
// returns true if it is a palindrome and returns false otherwise
bool checkPalindrome ( string s )
{
// This calculates the length of the string
int n = s.length();
// the for loop iterates until the first half of the string
// and checks first element with the last element,
// second element with second last element and so on.
// if those two characters are not same, hence we return false because
// this string is not a palindrome
for ( int i = 0; i <= n/2; i++ )
{
if ( s[i] != s[n-1-i] )
return false;
}
// if the above for loop executes completely ,
// this implies that the string is palindrome,
// hence we return true and exit
return true;
}
This happens to me when I'm using Jinja2 for templates. The problem can be solved by running the development server using the runserver_plus
command from django_extensions.
It uses the werkzeug debugger which also happens to be a lot better and has a very nice interactive debugging console. It does some ajax magic to launch a python shell at any frame (in the call stack) so you can debug.
It is possible to imitate this with HTML & CSS
If you really really want dynamically applied tooltips to work, this (not so performance and architecture friendly) solution can allow you to use browser rendered tooltips without resorting to JS. I can imagine situations where this would be better than JS.
If you have a fixed subset of title attribute values, then you can generate additional elements server-side and let the browser read title from another element positioned above the original one using CSS.
Example:
div{_x000D_
position: relative;_x000D_
}_x000D_
div > span{_x000D_
display: none;_x000D_

UPDLOCK is used when you want to lock a row or rows during a select statement for a future update statement. The future update might be the very next statement in the transaction.
Other sessions can still see the data. They just cannot obtain locks that are incompatiable with the UPDLOCK and/or HOLDLOCK.
You use UPDLOCK when you wan to keep other sessions from changing the rows you have locked. It restricts their ability to update or delete locked rows.
You use HOLDLOCK when you want to keep other sessions from changing any of the data you are looking at. It restricts their ability to insert, update, or delete the rows you have locked. This allows you to run the query again and see the same results.
Android Studio can now show this. Go to Build
> Analyze APK...
and select your apk. Then you can see the content of the AndroidManifset file.
No. You have to make your own like this:
boolean tryParseInt(String value) {
try {
Integer.parseInt(value);
return true;
} catch (NumberFormatException e) {
return false;
}
}
...and you can use it like this:
if (tryParseInt(input)) {
Integer.parseInt(input); // We now know that it's safe to parse
}
EDIT (Based on the comment by @Erk)
Something like follows should be better
public int tryParse(String value, int defaultVal) {
try {
return Integer.parseInt(value);
} catch (NumberFormatException e) {
return defaultVal;
}
}
When you overload this with a single string parameter method, it would be even better, which will enable using with the default value being optional.
public int tryParse(String value) {
return tryParse(value, 0)
}
Use the property TextWrapping
of the TextBlock
element:
<TextBlock Text="StackOverflow Forum"
Width="100"
TextWrapping="WrapWithOverflow"/>
You can write:
python
import keras
keras.__version__
When you set to install it "for all users" (not for the current user only), you won't need to route Android Studio for the JAVA_HOME. Of course, have JDK installed.
You can refer to https://curl.haxx.se/docs/http-cookies.html for a complete tutorial of how to work with cookies. You can use
curl -c /path/to/cookiefile http://yourhost/
to write to a cookie file and start engine and to use cookie you can use
curl -b /path/to/cookiefile http://yourhost/
to read cookies from and start the cookie engine, or if it isn't a file it will pass on the given string.
Use split
and map
function:
var str = "123, 124, 234,252";
var arr = str.split(",");
arr = arr.map(function (val) { return +val + 1; });
Notice +val
- string is casted to a number.
Or shorter:
var str = "123, 124, 234,252";
var arr = str.split(",").map(function (val) { return +val + 1; });
Today I'd advise against using +
operator to cast variable to a number. Instead I'd go with a more explicit but also more readable Number
call:
var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(function (val) {_x000D_
return Number(val) + 1;_x000D_
});_x000D_
console.log(arr);
_x000D_
ECMAScript 2015 introduced arrow function so it could be used instead to make the code more concise:
var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(val => Number(val) + 1);_x000D_
console.log(arr);
_x000D_
Another option would be as the return value for the stored procedure (I don't suggest this though, as that's usually best for error values).
I've included it as both when it's inserting a single row in cases where the stored procedure was being consumed by both other SQL procedures and a front-end which couldn't work with OUTPUT parameters (IBATIS in .NET I believe):
CREATE PROCEDURE My_Insert
@col1 VARCHAR(20),
@new_identity INT OUTPUT
AS
BEGIN
SET NOCOUNT ON
INSERT INTO My_Table (col1)
VALUES (@col1)
SELECT @new_identity = SCOPE_IDENTITY()
SELECT @new_identity AS id
RETURN
END
The output parameter is easier to work with in T-SQL when calling from other stored procedures IMO, but some programming languages have poor or no support for output parameters and work better with result sets.
I love the Shadow Wizard answer, which accually answers the question pretty nicelly. My jQuery twist on this which i use is here. http://jsfiddle.net/UJAe4/
After typing new value, the form is ready to send, just need to handle new values on the back end.
jQuery is:
(function ($)
{
$.fn.otherize = function (option_text, texts_placeholder_text) {
oSel = $(this);
option_id = oSel.attr('id') + '_other';
textbox_id = option_id + "_tb";
this.append("<option value='' id='" + option_id + "' class='otherize' >" + option_text + "</option>");
this.after("<input type='text' id='" + textbox_id + "' style='display: none; border-bottom: 1px solid black' placeholder='" + texts_placeholder_text + "'/>");
this.change(
function () {
oTbox = oSel.parent().children('#' + textbox_id);
oSel.children(':selected').hasClass('otherize') ? oTbox.show() : oTbox.hide();
});
$("#" + textbox_id).change(
function () {
$("#" + option_id).val($("#" + textbox_id).val());
});
};
}(jQuery));
So you apply this to the below html:
<form>
<select id="otherize_me">
<option value=1>option 1</option>
<option value=2>option 2</option>
<option value=3>option 3</option>
</select>
</form>
Just like this:
$(function () {
$("#otherize_me").otherize("other..", "put new option vallue here");
});
You can skip the var declaration and the stringify. Otherwise, that will work just fine.
$.ajax({
url: '/home/check',

Address2: "1001",

},
contentType: 'application/json; charset=utf-8',
success: function (data) {
alert(data.success);
},
error: function () {
alert("error");
}
});

On the other hand, you have PAGE that seems active and works in python 2.7 and py3k
As you indicate on your comment, none of these use the grid
geometry. As far as I can say the only GUI builder doing that could probably be Komodo Pro GUI Builder which was discontinued and made open source in ca. 2007. The code was located in the SpecTcl repository.
It seems to install fine on win7 although has not used it yet. This is an screenshot from my PC:
By the way, Rapyd Tk also had plans to implement grid geometry as in its documentation says it is not ready 'yet'. Unfortunately it seems 'nearly' abandoned.

I use lists to filter dataframes by whether or not they have a value %in% a list.
I had been manually creating lists by exporting a 1 column dataframe to Excel where I would add " ", around each element, before pasting into R: list <- c("el1", "el2", ...) which was usually followed by FilteredData <- subset(Data, Column %in% list).
After searching stackoverflow and not finding an intuitive way to convert a 1 column dataframe into a list, I am now posting my first ever stackoverflow contribution:
# assuming you have a 1 column dataframe called "df"
list <- c()
for(i in 1:nrow(df)){
list <- append(list, df[i,1])
}
View(list)
# This list is not a dataframe, it is a list of values
# You can filter a dataframe using "subset([Data], [Column] %in% list")
Regarding your first question.The pipe works as follows:
numberValue | number: {minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}
minFractionDigits: Minimum number of integer digits to show after the decimal point
maxFractionDigits: Maximum number of integer digits to show after the decimal point
2.Regarding your second question, Filter to zero decimal places as follows:
{{ numberValue | number: '1.0-0' }}

While the IANA-registered MIME type for ICO files is image/vnd.microsoft.icon, it was submitted to IANA in 2003 by a third party and is not recognised by Microsoft software, which uses image/x-icon instead.
If even the inventor of the ICO format does not use the official MIME type, I will use image/x-icon
, too.
Hadoop comes with a useful program called distcp
for copying large amounts of data to and from Hadoop Filesystems in parallel. The canonical use case for distcp is for transferring data between two HDFS clusters.
If the clusters are running identical versions of hadoop, then the hdfs scheme is appropriate to use.
$ hadoop distcp hdfs://namenode1/foo hdfs://namenode2/bar
The data in /foo
directory of namenode1 will be copied to /bar directory of namenode2. If the /bar
directory does not exist, it will create it. Also we can mention multiple source paths.
Similar to rsync
command, distcp command by default will skip the files that already exist. We can also use -overwrite
option to overwrite the existing files in destination directory. The option -update
will only update the files that have changed.
$ hadoop distcp -update hdfs://namenode1/foo hdfs://namenode2/bar/foo
distcp
can also be implemented as a MapReduce job where the work of copying is done by the maps that run in parallel across the cluster. There will be no reducers.
If trying to copy data between two HDFS clusters that are running different versions, the copy will process will fail, since the RPC systems are incompatible. In that case we need to use the read-only HTTP based HFTP filesystems to read from the source. Here the job has to run on destination cluster.
$ hadoop distcp hftp://namenode1:50070/foo hdfs://namenode2/bar
50070 is the default port number for namenode's embedded web server.
AFAIK the json module was added in version 2.6, see here. I'm guessing you can update your python installation to the latest stable 2.6 from this page.

Here's the fiddle.
I happen to really like this operator, but the reader should be taken into consideration.
You always have to balance code compactness with the time spent reading it, and in that it has some pretty severe flaws.
First of all, there is the Original Asker's case. He just spent an hour posting about it and reading the responses. How longer would it have taken the author to write every ?: as an if/then throughout the course of his entire life. Not an hour to be sure.
Secondly, in C-like languages, you get in the habit of simply knowing that conditionals are the first thing in the line. I noticed this when I was using Ruby and came across lines like:
callMethodWhatever(Long + Expression + with + syntax) if conditional
If I was a long time Ruby user I probably wouldn't have had a problem with this line, but coming from C, when you see "callMethodWhatever" as the first thing in the line, you expect it to be executed. The ?: is less cryptic, but still unusual enough as to throw a reader off.
The advantage, however, is a really cool feeling in your tummy when you can write a 3-line if statement in the space of 1 of the lines. Can't deny that :) But honestly, not necessarily more readable by 90% of the people out there simply because of its' rarity.
When it is truly an assignment based on a Boolean and values I don't have a problem with it, but it can easily be abused.
If it's a query you run often, you can store it in a file. Then any time you want to run it:
mysql < thefile
(with all the login and database flags of course)
You can make use of ImageIO
in order to load the image from an URL and then write it to a file. Something like this:
URL url = new URL("http://google.com/pathtoaimage.jpg");
BufferedImage img = ImageIO.read(url);
File file = new File("downloaded.jpg");
ImageIO.write(img, "jpg", file);
This also allows you to convert the image to some other format if needed.
You can't do this no. There is one attribute selector that matches exactly or partial until a - sign, but it wouldn't work here because you have multiple attributes. If the class name you are looking for would always be first, you could do this:
<html>
<head>
<title>Test Page</title>
<style type="text/css">
div[class|=status] { background-color:red; }
</style>
</head>
<body>
<div id='A' class='status-important bar-class'>A</div>
<div id='B' class='bar-class'>B</div>
<div id='C' class='status-low-priority bar-class'>C</div>
</body>
</html>
Note that this is just to point out which CSS attribute selector is the closest, it is not recommended to assume class names will always be in front since javascript could manipulate the attribute.
A very nice explanation is here-
A Normal Payload- // House on plot 1 { address: 'plot 1', owner: 'segun', type: 'duplex', color: 'green', rooms: '5', kitchens: '1', windows: 20 } PUT For Updated- // PUT request payload to update windows of House on plot 1 { address: 'plot 1', owner: 'segun', type: 'duplex', color: 'green', rooms: '5', kitchens: '1', windows: 21 } Note: In above payload we are trying to update windows from 20 to 21.
Now see the PATH payload- // Patch request payload to update windows on the House { windows: 21 }
Since PATCH is not idempotent, failed requests are not automatically re-attempted on the network. Also, if a PATCH request is made to a non-existent url e.g attempting to replace the front door of a non-existent building, it should simply fail without creating a new resource unlike PUT, which would create a new one using the payload. Come to think of it, it’ll be odd having a lone door at a house address.
Just for the record, here is the difference between If and IIf:
IIf(condition, true-part, false-part):
If(condition, true-part, false-part):
You normally use a tool like pip
to install wheels. Leave it to the tool to discover and download the file if this is for a project hosted on PyPI.
For this to work, you do need to install the wheel
package:
pip install wheel
You can then tell pip
to install the project (and it'll download the wheel if available), or the wheel file directly:
pip install project_name # discover, download and install
pip install wheel_file.whl # directly install the wheel
The wheel
module, once installed, also is runnable from the command line, you can use this to install already-downloaded wheels:
python -m wheel install wheel_file.whl
Also see the wheel
project documentation.
REST security is transport dependent while SOAP security is not.
REST inherits security measures from the underlying transport while SOAP defines its own via WS-Security.
When we talk about REST, over HTTP - all security measures applied HTTP are inherited and this is known as transport level security.
Transport level security, secures your message only while its on the wire - as soon as it leaves the wire, the message is no more secured.
But, with WS-Security, its message level security - even though the message leaves the transport channel it will be still protected. Also - with message level security you can partly encrypt the message [not the entire message, but only the parts you want] - but with transport level security you can't do it.
WS-Security has measures for authentication, integrity, confidentiality and non-repudiation while SSL doesn't support non repudiation [with 2-legged OAuth it does].
In performance-wise SSL is very much faster than WS-Security.

There are a couple of options there. The sample code is in Java, but a port to other languages should be straightforward.
WebElement myElement = driver.findElement(By.id("myDiv"));
WebElement parent = (WebElement) ((JavascriptExecutor) driver).executeScript(
"return arguments[0].parentNode;", myElement);
WebElement myElement = driver.findElement(By.id("myDiv"));
WebElement parent = myElement.findElement(By.xpath("./.."));
WebElement
Note: As you can see, for the JavaScript version you'll need the driver
. If you don't have direct access to it, you can retrieve it from the WebElement
using:
WebDriver driver = ((WrapsDriver) myElement).getWrappedDriver();
You Can use this code to read line by line in text file and You could also check about the first character is "*" then you can leave that..

If Not Left(ReadData, 1) = "*" then
'' you can write the variable ReadData into the database or file
End If

The below also happens to answer the Original Poster's question without, the "ugly" conditional code that some commenters have mentioned.
CONTIGUOUS NON-PRINTING Ruby Code
This will work in any mixed language Rails View file, e.g, *.html.erb, *.js.erb, *.rhtml
, etc.
This should also work with STD OUT/printing code, e.g. <%#= f.label :title %>
DETAILS:
Rather than use rails brackets on each line and commenting in front of each starting bracket as we usually do like this:
<%# if flash[:myErrors] %>
<%# if flash[:myErrors].any? %>
<%# if @post.id.nil? %>
<%# if @myPost!=-1 %>
<%# @post = @myPost %>
<%# else %>
<%# @post = Post.new %>
<%# end %>
<%# end %>
<%# end %>
<%# end %>
YOU CAN INSTEAD add only one comment (hashmark/poundsign) to the first open Rails bracket if you write your code as one large block... LIKE THIS:
<%#
if flash[:myErrors] then
if flash[:myErrors].any? then
if @post.id.nil? then
if @myPost!=-1 then
@post = @myPost
else
@post = Post.new
end
end
end
end
%>
I use a combination of Zelphir and Peter Gluck's answers. i.e.
<code>bovvered</code>
You can switch to shell mode temporarily by:
:! <command>
such as
:! ls
Try this
$('.yourchkboxes').change(function(){
$('.yourbutton').toggle($('.yourchkboxes:checked').length > 0);
});
So it will check for at least one checkbox is checked or not.
Give this style to the <p>
tag.
p {
word-break: break-all;
white-space: normal;
}
A funny way to remove all spaces from a variable is to use printf:
$ myvar='a cool variable with lots of spaces in it'
$ printf -v myvar '%s' $myvar
$ echo "$myvar"
acoolvariablewithlotsofspacesinit
It turns out it's slightly more efficient than myvar="${myvar// /}"
, but not safe regarding globs (*
) that can appear in the string. So don't use it in production code.
If you really really want to use this method and are really worried about the globbing thing (and you really should), you can use set -f
(which disables globbing altogether):
$ ls
file1 file2
$ myvar=' a cool variable with spaces and oh! no! there is a glob * in it'
$ echo "$myvar"
a cool variable with spaces and oh! no! there is a glob * in it
$ printf '%s' $myvar ; echo
acoolvariablewithspacesandoh!no!thereisaglobfile1file2init
$ # See the trouble? Let's fix it with set -f:
$ set -f
$ printf '%s' $myvar ; echo
acoolvariablewithspacesandoh!no!thereisaglob*init
$ # Since we like globbing, we unset the f option:
$ set +f
I posted this answer just because it's funny, not to use it in practice.
If you want to insert a raw HTML string no matter how complex, you can use:
insertAdjacentHTML
, with appropriate first argument:
'beforebegin' Before the element itself. 'afterbegin' Just inside the element, before its first child. 'beforeend' Just inside the element, after its last child. 'afterend' After the element itself.
Hint: you can always call Element.outerHTML
to get the HTML string representing the element to be inserted.
An example of usage:
document.getElementById("foo").insertAdjacentHTML("beforeBegin",
"<div><h1>I</h1><h2>was</h2><h3>inserted</h3></div>");
Caution: insertAdjacentHTML
does not preserve listeners that where attached with .addEventLisntener
.
I found lots of people meet this problem because the Multi-version Python, on my own vps (cent os 7 x64), I solved it in this way:
Find the file "_sqlite3.so"
find / -name _sqlite3.so
out: /usr/lib64/python2.7/lib-dynload/_sqlite3.so
Find the dir of python Standard library you want to use,
for me /usr/local/lib/python3.6/lib-dynload
Copy the file:
cp /usr/lib64/python2.7/lib-dynload/_sqlite3.so /usr/local/lib/python3.6/lib-dynload
Finally, everything will be ok.

IMO, JavaScript is gradually becoming a universal scripting standard: it is probably available in more products than any other scripting language (in Windows, it is available using the Windows Scripting Host). I have to clean out old files in lots of folders, so here is a JavaScript function to do that:
// run from an administrator command prompt (or from task scheduler with full rights): wscript jscript.js
// debug with: wscript /d /x jscript.js
var fs = WScript.CreateObject("Scripting.FileSystemObject");
clearFolder('C:\\temp\\cleanup');
function clearFolder(folderPath)
{
// calculate date 3 days ago
var dateNow = new Date();
var dateTest = new Date();
dateTest.setDate(dateNow.getDate() - 3);
var folder = fs.GetFolder(folderPath);
var files = folder.Files;
for( var it = new Enumerator(files); !it.atEnd(); it.moveNext() )
{
var file = it.item();
if( file.DateLastModified < dateTest)
{
var filename = file.name;
var ext = filename.split('.').pop().toLowerCase();
if (ext != 'exe' && ext != 'dll')
{
file.Delete(true);
}
}
}
var subfolders = new Enumerator(folder.SubFolders);
for (; !subfolders.atEnd(); subfolders.moveNext())
{
clearFolder(subfolders.item().Path);
}
}
For each folder to clear, just add another call to the clearFolder() function. This particular code also preserves exe and dll files, and cleans up subfolders as well.
UPDATE your_table
SET your_field = REPLACE(your_field, 'articles/updates/', 'articles/news/')
WHERE your_field LIKE '%articles/updates/%'
Now rows that were like
http://www.example.com/articles/updates/43
will be
http://www.example.com/articles/news/43
select t2.*
from t1 join t2 on t2.url='site.com/path/%' + cast(t1.id as varchar) + '%/more'
where t1.id > 9000
Using concat like suggested is even better though
Try-except-else is great for combining the EAFP pattern with duck-typing:
try:
cs = x.cleanupSet
except AttributeError:
pass
else:
for v in cs:
v.cleanup()
You might thing this naïve code is fine:
try:
for v in x.cleanupSet:
v.clenaup()
except AttributeError:
pass
This is a great way of accidentally hiding severe bugs in your code. I typo-ed cleanup there, but the AttributeError that would let me know is being swallowed. Worse, what if I'd written it correctly, but the cleanup method was occasionally being passed a user type that had a misnamed attribute, causing it to silently fail half-way through and leave a file unclosed? Good luck debugging that one.
For me it was a fresh NetCore application that was just not loading via IIS. When run standalone it was OK though.
I removed the <aspNetCore
line and then I got a normal error message from IIS saying that NetCoreModule could not be loaded. That module is required to understand this new web.config line.
The error message 0x8007000d
actually says that the web.config is malformed and that error shows up before the error loading module making this error message really crap. (and an unfortunate race condition problem)
I installed the NetCoreSDK and stopped and started IIS (restart didnt work)
The NetCore API started working via IIS as expected.
userInfos.GroupBy(userInfo => userInfo.metric)
.OrderBy(group => group.Key)
.Select(group => Tuple.Create(group.Key, group.Count()));
If you want to do multiple commands, you could use:
for I in `ls *.sql`
do
grep "foo" $I >> foo.log
grep "bar" $I >> bar.log
done
There is an issue with downloading npm dependencies due to network which you have. try to download the npm dependencies in open network . you won't get any issue. i am also faced this similar issue and resolved finally.
use below commands: npm install (it will download all depedencies) npm start to start the angular application
The DATE_ADD() function will do the trick. (You can also use the ADDTIME() function if you're running at least v4.1.1.)
For your query, this would be:
SELECT *
FROM courses
WHERE DATE_ADD(now(), INTERVAL 2 HOUR) > start_time
Or,
SELECT *
FROM courses
WHERE ADDTIME(now(), '02:00:00') > start_time
public interface IService {
String BASE_URL = "https://api.demo.com/";
@GET("Login") //i.e https://api.demo.com/Search?
Call<Products> getUserDetails(@Query("email") String emailID, @Query("password") String password)
}
It will be called this way. Considering you did the rest of the code already.
Call<Results> call = service.getUserDetails("[email protected]", "Password@123");
For example when a query is returned, it will look like this.
https://api.demo.com/[email protected]&password=Password@123
It goes something like:
from t1 in db.Table1
join t2 in db.Table2 on t1.field equals t2.field
select new { t1.field2, t2.field3}
It would be nice to have sensible names and fields for your tables for a better example. :)
Update
I think for your query this might be more appropriate:
var dealercontacts = from contact in DealerContact
join dealer in Dealer on contact.DealerId equals dealer.ID
select contact;
Since you are looking for the contacts, not the dealers.
I had the same problem but while doing updates. I solved it by
This warning comes because your dataframe x
is a copy of a slice. This is not easy to know why, but it has something to do with how you have come to the current state of it.
You can either create a proper dataframe
out of x by doing
x = x.copy()
This will remove the warning, but it is not the proper way
You should be using the DataFrame.loc
method, as the warning suggests, like this:
x.loc[:,'Mass32s'] = pandas.rolling_mean(x.Mass32, 5).shift(-2)
I solved this by installing the correct version of Jquery
that my project required using npm
Here's a less flexible alternative using unset():
$array = array(
1 => 'one',
2 => 'two',
3 => 'three'
);
$disallowed = array(1,3);
foreach($disallowed as $key){
unset($array[$key]);
}
The result of print_r($array)
being:
Array
(
[2] => two
)
This is not applicable if you want to keep the filtered values for later use but tidier, if you're certain that you don't.
On Windows you can also set the environment property OPENSSL_CONF
. For example from the commandline you can type:
set OPENSSL_CONF=c:/libs/openssl-0.9.8k/openssl.cnf
to validate it you can type:
echo %OPENSSL_CONF%
You can also set it as part of the computer's environmental variables so all users and services have it available by default. See, for example, Environment variables in Windows NT and How To Manage Environment Variables in Windows XP.
Now you can run openssl commands without having to pass the config location parameter.
You can simply use value_counts
on the series:
df['colour'].value_counts().plot(kind='bar')
Models don't exist in isolation. The structures you'd define for a simulation of cars entering a car park, an embedded system which guides you to a free space, a car parking billing system or for the automated gates/ticket machines usual in car parks are all different.
