After done trying everything that I found on this issue, in eclipse,
I selected my project --> right click --> Run as --> Maven generate-sources
Then I re-ran my TestNG project and it ran perfectly fine without any issues.Hope that helps :)
One of the reasons for this error is the use of the jaxb implementation from the jdk. I am not sure why such a problem can appear in pretty simple xml parsing situations. You may use the latest version of the jaxb library from a public maven repository:
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.2.12</version>
</dependency>
Apparently the change event is not fired if a selection already exists when using data. I ended up updating the data manually on select to resolve the problem.
$("#search_code").on("select2-selecting", function(e) {
$("#search_code").select2("data",e.choice);
});
I know this is pretty late but hopefully this answer will save others time.

You should debug first, to help identify your level of XML hell. In my opinion, the first step is to add
-Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl
-Djavax.xml.transform.TransformerFactory=com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl
-Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl
to the command line. If that works, then start excluding libraries. If not, then add
-Djaxp.debug=1
to the command-line.
It means that you compiled your classes under a specific JDK, but then try to run them under older version of JDK.
Are you sure that the XML file is in the correct character encoding? FileReader
always uses the platform default encoding, so if the "working" server had a default encoding of (say) ISO-8859-1 and the "problem" server uses UTF-8 you would see this error if the XML contains any non-ASCII characters.
Does it work if you create the InputSource from a FileInputStream instead of a FileReader?
Actually, I solved the problem. I run it by eclipse jetty plugin.
I didn't have the JDK lib in my eclipse, that's why the message keep showing that I need the full JDK installed, that's the main reason.
I installed two versions of jetty plugin, wich is jetty7 and jetty8. I think they conflict with each other or something, so I removed the jetty7, and it works!
I resolved the issue by converting the source feed from http://www.news18.com/rss/politics.xml to https://www.news18.com/rss/politics.xml
with http below code was creating an empty file which was causing the issue down the line
String feedUrl = "https://www.news18.com/rss/politics.xml";
File feedXmlFile = null;
try {
feedXmlFile =new File("C://opinionpoll/newsFeed.xml");
FileUtils.copyURLToFile(new URL(feedUrl),feedXmlFile);
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(feedXmlFile);
Many solutions have been given, and the internals are briefly touched by @Sriram and @ptomli as well. I just want to add a few references to the source code to help understand what is happening under the hood.
By default (i.e. no extra annotations used at all except @XmlRootElement
on the root class), JABX tries to marshal things exposed via two ways:
Notice that if a field is (or method returns) null
, it will not be written into the output.
Now if @XmlElement
is used, non-public things (could be fields or getter methods) can be marshalled as well.
But the two ways, i.e. fields and getter-methods, must not conflict with each other. Otherwise you get the exception.
List<String> arrayList = new ArrayList<String>();
for (String s : arrayList) {
if(s.equals(value)){
//do something
}
}
or
for (int i = 0; i < arrayList.size(); i++) {
if(arrayList.get(i).equals(value)){
//do something
}
}
But be carefull ArrayList can hold null values. So comparation should be
value.equals(arrayList.get(i))
when you are sure that value is not null or you should check if given element is null.
The error message is actually correct if not obvious. It says that your DOCTYPE must have a SYSTEM identifier. I assume yours only has a public identifier.
You'll get the error with (for instance):
<!DOCTYPE persistence PUBLIC
"http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
You won't with:
<!DOCTYPE persistence PUBLIC
"http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" "">
Notice ""
at the end in the second one -- that's the system identifier. The error message is confusing: it should say that you need a system identifier, not that you need a space between the publicId and the (non-existent) systemId.
By the way, an empty system identifier might not be ideal, but it might be enough to get you moving.
Use display instead of visibility. display: none for invisible and no setting for visible.
The character 0x0C is be invalid in XML 1.0 but would be a valid character in XML 1.1. So unless the xml file specifies the version as 1.1 in the prolog it is simply invalid and you should complain to the producer of this file.
The easiest way to disable a link is simply not to show it. Run this function whenever you want to test if your condition is met to hide the Previous button (replace if (true)
with your condition):
var testHideNav = function() {
var aTags = document.getElementsByTagName('a'),
atl = aTags.length,
i;
for (i = 0; i < atl; i++) {
if (aTags[i].innerText == "Previous") {
if (true) { // your condition to disable previous
aTags[i].style.visibility = "hidden";
} else {
aTags[i].style.visibility = "visible";
}
} else if (aTags[i].innerText == "Next") {
if (false) { // your condition to disable next
aTags[i].style.visibility = "hidden";
} else {
aTags[i].style.visibility = "visible";
}
}
}
};
Then run testHideNav()
whenever you need to make the check if your condition has changed.
The message is actually pretty clear: something creates a ThreadLocal
with value of type org.apache.axis.MessageContext
- this is a great hint. It most likely means that Apache Axis framework forgot/failed to cleanup after itself. The same problem occurred for instance in Logback. You shouldn't bother much, but reporting a bug to Axis team might be a good idea.
Tomcat reports this error because the ThreadLocal
s are created per HTTP worker threads. Your application is undeployed but HTTP threads remain - and these ThreadLocal
s as well. This may lead to memory leaks (org.apache.axis.MessageContext
can't be unloaded) and some issues when these threads are reused in the future.
For details see: http://wiki.apache.org/tomcat/MemoryLeakProtection
to simply remove it, paste your xml file into notepad, you'll see the extra character before the first tag. Remove it & paste back into your file - bof
The document looks fine to me but I suspect that it contains invisible characters. Open it in a hex editor to check that there really isn't anything before the very first "<". Make sure the spaces in the XML header are spaces. Maybe delete the space before "?>". Check which line breaks are used.
Make sure the document is proper UTF-8. Some windows editors save the document as UTF-16 (i.e. every second byte is 0).
Is EmailHandler
really the full name of your servlet class, i.e. it's not in a package like com.something.EmailHandler
? It has to be fully-qualified in web.xml
.
You should check that the spring.handlers
and spring.schemas
files are on the classpath and have the right content.
This can be done with ClassLoader.getResource(..)
. You can run the method with a remote debugger in the runtime environment. The extensible XML authoring setup is described in the Spring Reference B.5. Registering the handler and the schema.
Normally, the files should be in the spring jar (springframework.jar/META-INF/) and on the classpath when Spring can be initiated.

When you run cmake add the additional parameter -D OPENCV_GENERATE_PKGCONFIG=YES (this will generate opencv.pc file)
Then make and sudo make install as before.
Use the name opencv4 instead of just opencv Eg:-
pkg-config --modversion opencv4
TL;DR
npm uninstall node-sass
npm install [email protected]
Or, if using yarn (default in newer CRA versions)
yarn remove node-sass
yarn add [email protected]
Edit2: sass-loader v10.0.5 fixes it. Problem is, you might not be using it as a project dependency, but more as a dependency of your dependencies. CRA uses a fixed version, angular-cli locks to node-sass v4 an so on.
The recommendation for now is: if you're installing just node-sass check below workaround (and the note). If you're working on a blank project and you can manage your webpack configuration (not using CRA or a CLI to scaffold your project) install latest sass-loader.
Edit: this error comes from sass-loader. There is a semver mismatch since node-sass @latest is v5.0.0 and sass-loader expects ^4.0.0.
There is an open issue on their repository with an associated fix that needs to be reviewed. Until then, refer to the solution below.
Workaround: don't install node-sass 5.0.0 yet (major version was just bumped).
Uninstall node-sass
npm uninstall node-sass
Then install the latest version (before 5.0)
npm install [email protected]
Note: LibSass (hence node-sass as well) is deprecated and dart-sass is the recommended implementation. You can use sass
instead, which is a node distribution of dart-sass compiled to pure JavaScript.
Be warned though:
Be careful using this approach. React-scripts uses sass-loader v8, which prefers node-sass to sass (which has some syntax not supported by node-sass). If both are installed and the user worked with sass, this could lead to errors on css compilation
The issue here is that you've opened a file and read its contents so the cursor is at the end of the file. By writing to the same file handle, you're essentially appending to the file.
The easiest solution would be to close the file after you've read it in, then reopen it for writing.
with open("replayScript.json", "r") as jsonFile:
data = json.load(jsonFile)
data["location"] = "NewPath"
with open("replayScript.json", "w") as jsonFile:
json.dump(data, jsonFile)
Alternatively, you can use seek()
to move the cursor back to the beginning of the file then start writing, followed by a truncate()
to deal with the case where the new data is smaller than the previous.
with open("replayScript.json", "r+") as jsonFile:
data = json.load(jsonFile)
data["location"] = "NewPath"
jsonFile.seek(0) # rewind
json.dump(data, jsonFile)
jsonFile.truncate()
You can also just return string if you know that's the only thing the method will ever return. For example:
public string MyActionName() {
return "Hi there!";
}
I just had this issue, but only when I published to my website, on my local debug it ran fine. I found I had to use the FTP from my webhost and go into my publish dir and delete the files in the BIN folder, deleting them locally did nothing when I published.
If you attach your code as a text file and your recipient(s) have "show attachments inline" option set (I believe it's set by default), Outlook should not mangle your code but it will be copy/paste-able directly from email.
You can center absolute items by providing the left property with the width of the device divided by two and subtracting out half of the element you'd like to center's width.
For example, your style might look something like this.
bottom: {
position: 'absolute',
left: (Dimensions.get('window').width / 2) - 25,
top: height*0.93,
}
I found this example also tricky. Why that in the 2nd loop at the last iteration nothing happens ($v stays 'two'), is that $v points to $a[3] (and vice versa), so it cannot assign value to itself, so it keeps the previous assigned value :)
Here is my solution using a temporary hidden form.
//Create an hidden form
var form = $('<form>', {'method': 'POST', 'action': this.href}).hide();
//Add params
var params = { ...your params... };
$.each(params, function (k, v) {
form.append($('<input>', {'type': 'hidden', 'name': k, 'value': v}));
});
//Make it part of the document and submit
$('body').append(form);
form.submit();
//Clean up
form.remove();
Note that I massively use JQuery but you can do the same with native JS.
I used this in my code:
<div class="sticky-top h-100">
<nav id="sidebar" class="vh-100">
....
this cause your sidebar height become 100% and fixed at top.

Revised Answer
If you're not calling this code from another program, an option is to skip PL/SQL and do it strictly in SQL using bind variables:
var myname varchar2(20);
exec :myname := 'Tom';
SELECT *
FROM Customers
WHERE Name = :myname;
In many tools (such as Toad and SQL Developer), omitting the var
and exec
statements will cause the program to prompt you for the value.
Original Answer
A big difference between T-SQL and PL/SQL is that Oracle doesn't let you implicitly return the result of a query. The result always has to be explicitly returned in some fashion. The simplest way is to use DBMS_OUTPUT
(roughly equivalent to print
) to output the variable:
DECLARE
myname varchar2(20);
BEGIN
myname := 'Tom';
dbms_output.print_line(myname);
END;
This isn't terribly helpful if you're trying to return a result set, however. In that case, you'll either want to return a collection or a refcursor. However, using either of those solutions would require wrapping your code in a function or procedure and running the function/procedure from something that's capable of consuming the results. A function that worked in this way might look something like this:
CREATE FUNCTION my_function (myname in varchar2)
my_refcursor out sys_refcursor
BEGIN
open my_refcursor for
SELECT *
FROM Customers
WHERE Name = myname;
return my_refcursor;
END my_function;
If you have mistakenly named the local name as "origin", you may remove it with the following:
git remote rm origin
Follow these steps
Yippee....your code will run:)
TypeScript, React, index.html
//conf.js:
window.bar = "bar";
//index.html
<script type="module" src="./conf.js"></script>
//tsconfig.json
"include": ["typings-custom/**/*.ts"]
//typings-custom/typings.d.ts
declare var bar:string;
//App.tsx
console.log('bar', window.bar);
or
console.log('bar', bar);
Use q
flag for quiet mode, and tell wget
to output to stdout with O-
(uppercase o) and redirect to /dev/null
to discard the output:
wget -qO- $url &> /dev/null
>
redirects application output (to a file). if >
is preceded by ampersand, shell redirects all outputs (error and normal) to the file right of >
. If you don't specify ampersand, then only normal output is redirected.
./app &> file # redirect error and standard output to file
./app > file # redirect standard output to file
./app 2> file # redirect error output to file
if file is /dev/null
then all is discarded.
This works as well, and simpler:
wget -O/dev/null -q $url
IsValidDate: function(date) {
var regex = /\d{1,2}\/\d{1,2}\/\d{4}/;
if (!regex.test(date)) return false;
var day = Number(date.split("/")[1]);
date = new Date(date);
if (date && date.getDate() != day) return false;
return true;
}
How can we read data from a text file and store in a String Variable?
Err, read data from the file and store it in a String variable. It's just code. Not a real question so far.
Is it possible to pass the filename in a method and it would return the String which is the text from the file.
Yes it's possible. It's also a very bad idea. You should deal with the file a part at a time, for example a line at a time. Reading the entire file into memory before you process any of it adds latency; wastes memory; and assumes that the entire file will fit into memory. One day it won't. You don't want to do it this way.
Do not use the *
selector as that will apply to all elements on the page. Suppose you have a structure like this:
...
<body>
<div id="content">
<b>This is the main container.</b>
</div>
</body>
</html>
You can then center the #content
div using:
#content {
width: 400px;
margin: 0 auto;
background-color: #66ffff;
}
Don't know what you've seen elsewhere but this is the way to go. The * { margin: 0; padding: 0; }
snippet you've seen is for resetting browser's default definitions for all browsers to make your site behave similarly on all browsers, this has nothing to do with centering the main container.
Most browsers apply a default margin and padding to some elements which usually isn't consistent with other browsers' implementations. This is why it is often considered smart to use this kind of 'resetting'. The reset snippet you presented is the most simplest of reset stylesheets, you can read more about the subject here:
You can use pandas methods where
and mask
:
df['color'] = 'green'
df['color'] = df['color'].where(df['Set']=='Z', other='red')
# Replace values where the condition is False
or
df['color'] = 'red'
df['color'] = df['color'].mask(df['Set']=='Z', other='green')
# Replace values where the condition is True
Output:
Type Set color
1 A Z green
2 B Z green
3 B X red
4 C Y red

Setting dataType:'json'
will parse JSON for you:
$.ajax({
type: 'GET',
url: 'http://example/functions.php',
data: {get_param: 'value'},
dataType: 'json',
success: function (data) {
var names = data
$('#cand').html(data);
}
});
Or else you can use parseJSON
:
var parsedJson = $.parseJSON(jsonToBeParsed);
Then you can iterate the following:
var j ='[{"id":"1","name":"test1"},{"id":"2","name":"test2"},{"id":"3","name":"test3"},{"id":"4","name":"test4"},{"id":"5","name":"test5"}]';
...by using $().each
:
var json = $.parseJSON(j);
$(json).each(function (i, val) {
$.each(val, function (k, v) {
console.log(k + " : " + v);
});
});
Update your environment variables
Ensure the reference to java/bin is up to date in 'Path'; This may be automatic if you have JAVA_HOME or equivalent set. If JAVA_HOME is set, simply update it to refer to the older JRE installation.
To automatically sync your forked repository with the parent repository, you could use the Pull App on GitHub.
Refer to the Readme for more details.
For advanced setup where you want to preserve your changes done to the forked repository, refer to my answer on a similar question here.
Even if fileno(FILE *)
may return a file descriptor, be VERY careful not to bypass stdio's buffer. If there is buffer data (either read or unflushed write), reads/writes from the file descriptor might give you unexpected results.
To answer one of the side questions, to convert a file descriptor to a FILE pointer, use fdopen(3)
You should use git pull --rebase
when
Indeed -- why not then? It's more clear, and doesn't impose a logical grouping on your commits.
Ok, I suppose it needs some clarification. In Git, as you probably know, you're encouraged to branch and merge. Your local branch, into which you pull changes, and remote branch are, actually, different branches, and git pull
is about merging them. It's reasonable, since you push not very often and usually accumulate a number of changes before they constitute a completed feature.
However, sometimes--by whatever reason--you think that it would actually be better if these two--remote and local--were one branch. Like in SVN. It is here where git pull --rebase
comes into play. You no longer merge--you actually commit on top of the remote branch. That's what it actually is about.
Whether it's dangerous or not is the question of whether you are treating local and remote branch as one inseparable thing. Sometimes it's reasonable (when your changes are small, or if you're at the beginning of a robust development, when important changes are brought in by small commits). Sometimes it's not (when you'd normally create another branch, but you were too lazy to do that). But that's a different question.

As simple as that.
I also hit this problem and it seems that both most upvoted answers work but there is a tiny problem, webpack throws an error into browser console (Error: Cannot find module './undefined' at webpackContextResolve) which is not very nice.
So I've solved it a bit differently. The whole problem with variable inside require statement is that require statement is executed during bundling and variable inside that statement appears only during app execution in browser. So webpack sees required image as undefined either way, as during compilation that variable doesn't exist.
What I did is place random image into require statement and hiding that image in css, so nobody sees it.
// template
<img class="user-image-svg" :class="[this.hidden? 'hidden' : '']" :src="userAvatar" alt />
//js
data() {
return {
userAvatar: require('@/assets/avatar1.svg'),
hidden: true
}
}
//css
.hidden {display: none}
Image comes as part of information from database via Vuex and is mapped to component as a computed
computed: {
user() {
return this.$store.state.auth.user;
}
}
So once this information is available I swap initial image to the real one
watch: {
user(userData) {
this.userAvatar = require(`@/assets/${userData.avatar}`);
this.hidden = false;
}
}
The Build number is an internal number that indicates the current state of the app. It differs from the Version number in that it's typically not user facing and doesn't denote any difference/features/upgrades like a version number typically would.
Think of it like this:
CFBundleVersion
): The number of the build. Usually you start this at 1 and increase by 1 with each build of the app. It quickly allows for comparisons of which build is more recent and it denotes the sense of progress of the codebase. These can be overwhelmingly valuable when working with QA and needing to be sure bugs are logged against the right builds.CFBundleShortVersionString
): The user-facing number you are using to denote this version of your app. Usually this follows a Major.minor version scheme (e.g. MyAwesomeApp 1.2) to let users know which releases are smaller maintenance updates and which are big deal new features.To use this effectively in your projects, Apple provides a great tool called agvtool
. I highly recommend using this as it is MUCH more simple than scripting up plist changes. It allows you to easily set both the build number and the marketing version. It is particularly useful when scripting (for instance, easily updating the build number on each build or even querying what the current build number is). It can even do more exotic things like tag your SVN for you when you update the build number.
To use it:
agvtool new-version 1
(set the Build number to 1)agvtool new-marketing-version 1.0
(set the Marketing version to 1.0)See the man page of agvtool
for a ton of good info

If you're using Spring Boot 1.4, it has an awesome way of doing this. Just use new brand @SpringBootTest
on your class and @MockBean
on the field and Spring Boot will create a mock of this type and it will inject it into the context (instead of injecting the original one):
@RunWith(SpringRunner.class)
@SpringBootTest
public class MyTests {
@MockBean
private RemoteService remoteService;
@Autowired
private Reverser reverser;
@Test
public void exampleTest() {
// RemoteService has been injected into the reverser bean
given(this.remoteService.someCall()).willReturn("mock");
String reverse = reverser.reverseSomeCall();
assertThat(reverse).isEqualTo("kcom");
}
}
On the other hand, if you're not using Spring Boot or are you using a previous version, you'll have to do a bit more work:
Create a @Configuration
bean that injects your mocks into Spring context:
@Configuration
@Profile("useMocks")
public class MockConfigurer {
@Bean
@Primary
public MyBean myBeanSpy() {
return mock(MyBean.class);
}
}
Using @Primary
annotation you're telling spring that this bean has priority if no qualifier are specified.
Make sure you annotate the class with @Profile("useMocks")
in order to control which classes will use the mock and which ones will use the real bean.
Finally, in your test, activate userMocks
profile:
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = {Application.class})
@WebIntegrationTest
@ActiveProfiles(profiles={"useMocks"})
public class YourIntegrationTestIT {
@Inject
private MyBean myBean; //It will be the mock!
@Test
public void test() {
....
}
}
If you don't want to use the mock but the real bean, just don't activate useMocks
profile:
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = {Application.class})
@WebIntegrationTest
public class AnotherIntegrationTestIT {
@Inject
private MyBean myBean; //It will be the real implementation!
@Test
public void test() {
....
}
}
Am using angular 5 and for an ngif to work for me that is in a ngfor, I had to use animateChild and in the user-detail component I used the *ngIf="user.expanded" to show hide user and it worked for entering a leaving

The default display
property for a table is display:table;
. The only other useful value is inline-table
. All other display
values are invalid for table elements.
There isn't an auto
option to reset it to default, although if you're working in Javascript, you can set it to an empty string, which will do the trick.
width:auto;
is valid, but isn't the default. The default width for a table is 100%
, whereas width:auto;
will make the element only take up as much width as it needs to.
min-width:auto;
isn't allowed. If you set min-width
, it must have a value, but setting it to zero is probably as good as resetting it to default.
You have to workaround this via static application context accessor approach:
@Component
public class StaticContextAccessor {
private static StaticContextAccessor instance;
@Autowired
private ApplicationContext applicationContext;
@PostConstruct
public void registerInstance() {
instance = this;
}
public static <T> T getBean(Class<T> clazz) {
return instance.applicationContext.getBean(clazz);
}
}
Then you can access bean instances in a static manner.
public class Boo {
public static void randomMethod() {
StaticContextAccessor.getBean(Foo.class).doStuff();
}
}
I've been able to solve this by using a hack involving import *
. It even works for both named and default exports!
For a named export:
// dependency.js
export const doSomething = (y) => console.log(y)
// myModule.js
import { doSomething } from './dependency';
export default (x) => {
doSomething(x * 2);
}
// myModule-test.js
import myModule from '../myModule';
import * as dependency from '../dependency';
describe('myModule', () => {
it('calls the dependency with double the input', () => {
dependency.doSomething = jest.fn(); // Mutate the named export
myModule(2);
expect(dependency.doSomething).toBeCalledWith(4);
});
});
Or for a default export:
// dependency.js
export default (y) => console.log(y)
// myModule.js
import dependency from './dependency'; // Note lack of curlies
export default (x) => {
dependency(x * 2);
}
// myModule-test.js
import myModule from '../myModule';
import * as dependency from '../dependency';
describe('myModule', () => {
it('calls the dependency with double the input', () => {
dependency.default = jest.fn(); // Mutate the default export
myModule(2);
expect(dependency.default).toBeCalledWith(4); // Assert against the default
});
});
As Mihai Damian quite rightly pointed out below, this is mutating the module object of dependency
, and so it will 'leak' across to other tests. So if you use this approach you should store the original value and then set it back again after each test.
To do this easily with Jest, use the spyOn() method instead of jest.fn()
, because it supports easily restoring its original value, therefore avoiding before mentioned 'leaking'.
If you can't put value on buttons. I have just a rough solution. Put a hidden field. And when one of the buttons are clicked before submitting, populate the value of hidden field with like say 1 when first button clicked and 2 if second one is clicked. and in submit page check for the value of this hidden field to determine which one is clicked.
For your case, you may use regex:
boolean checkFormat;
if (input.matches("([0-9]{2})/([0-9]{2})/([0-9]{4})"))
checkFormat=true;
else
checkFormat=false;
For a larger scope or if you want a flexible solution, refer to MadProgrammer's answer.
Almost 5 years after posting this answer, I realize that this is a stupid way to validate a date format. But i'll just leave this here to tell people that using regex to validate a date is unacceptable
You can also look in the registry.
using System.IO;
using Microsoft.Win32;
string GetMimeType(FileInfo fileInfo)
{
string mimeType = "application/unknown";
RegistryKey regKey = Registry.ClassesRoot.OpenSubKey(
fileInfo.Extension.ToLower()
);
if(regKey != null)
{
object contentType = regKey.GetValue("Content Type");
if(contentType != null)
mimeType = contentType.ToString();
}
return mimeType;
}
One way or another you're going to have to tap into a database of MIMEs - whether they're mapped from extensions or magic numbers is somewhat trivial - windows registry is one such place. For a platform independent solution though one would have to ship this DB with the code (or as a standalone library).
AngularJS provides a simple and concise way to associate routes with controllers and templates using a $routeProvider
object. While recently updating an application to the latest release (1.2 RC1 at the current time) I realized that $routeProvider
isn’t available in the standard angular.js script any longer.
After reading through the change log I realized that routing is now a separate module (a great move I think) as well as animation and a few others. As a result, standard module definitions and config code like the following won’t work any longer if you’re moving to the 1.2 (or future) release:
var app = angular.module('customersApp', []);
app.config(function ($routeProvider) {
$routeProvider.when('/', {
controller: 'customersController',
templateUrl: '/app/views/customers.html'
});
});
How do you fix it?
Simply add angular-route.js in addition to angular.js to your page (grab a version of angular-route.js here – keep in mind it’s currently a release candidate version which will be updated) and change the module definition to look like the following:
var app = angular.module('customersApp', ['ngRoute']);
If you’re using animations you’ll need angular-animation.js and also need to reference the appropriate module:
var app = angular.module('customersApp', ['ngRoute', 'ngAnimate']);
Your Code can be as follows:
var app = angular.module('app', ['ngRoute']);
app.config(function($routeProvider) {
$routeProvider
.when('/controllerone', {
controller: 'friendDetails',
templateUrl: 'controller3.html'
}, {
controller: 'friendsName',
templateUrl: 'controller3.html'
}
)
.when('/controllerTwo', {
controller: 'simpleControoller',
templateUrl: 'views.html'
})
.when('/controllerThree', {
controller: 'simpleControoller',
templateUrl: 'view2.html'
})
.otherwise({
redirectTo: '/'
});
});
There's sweet Alert version 1 and 2. Actual version 2 works with HTML nodes.
I have a Sweet Alert 2 with a data form that looks this way:
<script>
var form = document.createElement("div");
form.innerHTML = `
<span id="tfHours">0</span> hours<br>
<input style="width:90%;" type="range" name="tfHours" value=0 step=1 min=0 max=25
onchange="window.changeHours(this.value)"
oninput="window.changeHours(this.value)"
><br>
<span id="tfMinutes">0</span> min<br>
<input style="width:60%;" type="range" name="tfMinutes" value=0 step=5 min=0 max=60
onchange="window.changeMinutes(this.value)"
oninput="window.changeMinutes(this.value)"
>`;
swal({
title: 'Request time to XXX',
text: 'Select time to send / request',
content: form,
buttons: {
cancel: "Cancel",
catch: {
text: "Create",
value: 5,
},
}
}).then((value) => {
console.log(value);
});
window.changeHours = function (value){
var tfHours = document.getElementById("tfHours");
tfHours.innerHTML = value;
}
window.changeMinutes = function (value){
var tfMinutes = document.getElementById("tfMinutes");
tfMinutes.innerHTML = value;
}
It looks like your utf-8 is being interpreted as iso8859-1 or Win-1250 at some point.
When you say "In my database I have a few instances of bad encodings" - how did you check this? Through your app, phpmyadmin or the command line client? Are all utf-8 encodings showing up like this or only some? Is it possible you had the encodings wrong and it has been incorrectly converted from iso8859-1 to utf-8 when it was utf-8 already?
Try this:
DateTime.Now.ToString("HH:mm:ss tt")
For other formats, you can check this site: C# DateTime Format
split()
inbuilt function will only separate the value on the basis of certain condition but in the single word, it cannot fulfill the condition. So, it can be solved with the help of list()
. It internally calls the Array and it will store the value on the basis of an array.
Suppose,
a = "bottle"
a.split() // will only return the word but not split the every single char.
a = "bottle"
list(a) // will separate ['b','o','t','t','l','e']
You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.
Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String
'Assign data to first item in array
compArray(1) = "asdf"
'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"
'Prints "ErrorState"
Debug.Print Computers("Computer Name")
Collections cannot be sorted so if you need to sort data you will probably want to use an array.

Another great site to help you get started is http://www.cpearson.com/Excel/Topic.aspx
Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!
Edit:
Sub ArrayExample()
Dim subject As String
Dim TestArray() As String
Dim counter As Long
subject = "Example"
counter = Len(subject)
ReDim TestArray(1 To counter) As String
For counter = 1 To Len(subject)
TestArray(counter) = Right(Left(subject, counter), 1)
Next
End Sub
You can fire an event yourself in ngOnInit()
of your Angular root component and then listen for this event outside of Angular.
This is Dart code (I don't know TypeScript) but should't be to hard to translate
@Component(selector: 'app-element')
@View(
templateUrl: 'app_element.html',
)
class AppElement implements OnInit {
ElementRef elementRef;
AppElement(this.elementRef);
void ngOnInit() {
DOM.dispatchEvent(elementRef.nativeElement, new CustomEvent('angular-ready'));
}
}
The recommended way to do this:
Nowadays, you should really be using DateTime objects for any date/time math. This requires you to have a PHP version >= 5.2. As shown in Glavic's answer, you can use the following:
$monthNum = 3;
$dateObj = DateTime::createFromFormat('!m', $monthNum);
$monthName = $dateObj->format('F'); // March
The !
formatting character is used to reset everything to the Unix epoch. The m
format character is the numeric representation of a month, with leading zeroes.
Alternative solution:
If you're using an older PHP version and can't upgrade at the moment, you could this solution.
The second parameter of date()
function accepts a timestamp, and you could use mktime()
to create one, like so:
$monthNum = 3;
$monthName = date('F', mktime(0, 0, 0, $monthNum, 10)); // March
If you want the 3-letter month name like Mar
, change F
to M
. The list of all available formatting options can be found in the PHP manual documentation.
Wikipedia tells what comma operator does:
"In the C and C++ programming languages, the comma operator (represented by the token ,
) is a binary operator that evaluates its first operand and discards the result, and then evaluates the second operand and returns this value (and type)."
I am not an expert in python but you could try: say
i = (1,2)
res = lambda i: (i[1],i[0])
print 'res(1, 2) = {0}'.format(res(1, 2))
above would give o/p as:
res(1, 2) = (2,1)
arr.length = Math.min(arr.length, 5)
If you are concatenating the enum with a string you can override toString method to return the int:
public String toString() {
return value + "";
}
Then you could simply use:
String something = "foo" + DownloadType.AUDIO;
and the toString() method will be invoked.
Note that using toString() programmatically is generally considered poor practice - it is intended for human eyes only, however this is the only way to achieve what you're asking.
Each image has a resource-number, which is an integer. Pass this number to "setImageResource" and you should be ok.
Check this link for further information:
http://developer.android.com/guide/topics/resources/accessing-resources.html
e.g.:
imageView.setImageResource(R.drawable.myimage);
For case-insensitive string search, use index
(or rindex
) in combination with fc
. This example expands on the answer by Eugene Yarmash:
use feature qw( fc );
my $str = "Abc";
my $substr = "aB";
print "found" if index( fc $str, fc $substr ) != -1;
# Prints: found
print "found" if rindex( fc $str, fc $substr ) != -1;
# Prints: found
$str = "Abc";
$substr = "bA";
print "found" if index( fc $str, fc $substr ) != -1;
# Prints nothing
print "found" if rindex( fc $str, fc $substr ) != -1;
# Prints nothing
Both index
and rindex
return -1
if the substring is not found.
And fc
returns a casefolded version of its string argument, and should be used here instead of the (more familiar) uc
or lc
. Remember to enable this function, for example with use feature qw( fc );
.
If I recall correctly Twig doesn't support ||
and &&
operators, but requires or
and and
to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.
{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}
Expressions
Expressions can be used in {% blocks %} and ${ expressions }.
Operator Description
== Does the left expression equal the right expression?
+ Convert both arguments into a number and add them.
- Convert both arguments into a number and substract them.
* Convert both arguments into a number and multiply them.
/ Convert both arguments into a number and divide them.
% Convert both arguments into a number and calculate the rest of the integer division.
~ Convert both arguments into a string and concatenate them.
or True if the left or the right expression is true.
and True if the left and the right expression is true.
not Negate the expression.
For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:
{% if (foo and bar) or (fizz and (foo + bar == 3)) %}
Please see this Question
You can only replace a "dynamically added fragment".
So, if you want to add a dynamic fragment, see this example.
PIPESTATUS[@] must be copied to an array immediately after the pipe command returns. Any reads of PIPESTATUS[@] will erase the contents. Copy it to another array if you plan on checking the status of all pipe commands. "$?" is the same value as the last element of "${PIPESTATUS[@]}", and reading it seems to destroy "${PIPESTATUS[@]}", but I haven't absolutely verified this.
declare -a PSA
cmd1 | cmd2 | cmd3
PSA=( "${PIPESTATUS[@]}" )
This will not work if the pipe is in a sub-shell. For a solution to that problem,
see bash pipestatus in backticked command?
Thinking in terms of C++,
val x: T
is analogous to constant pointer to non-constant data
T* const x;
while
var x: T
is analogous to non-constant pointer to non-constant data
T* x;
Favoring val
over var
increases immutability of the codebase which can facilitate its correctness, concurrency and understandability.
To understand the meaning of having a constant pointer to non-constant data consider the following Scala snippet:
val m = scala.collection.mutable.Map(1 -> "picard")
m // res0: scala.collection.mutable.Map[Int,String] = HashMap(1 -> picard)
Here the "pointer" val m
is constant so we cannot re-assign it to point to something else like so
m = n // error: reassignment to val
however we can indeed change the non-constant data itself that m
points to like so
m.put(2, "worf")
m // res1: scala.collection.mutable.Map[Int,String] = HashMap(1 -> picard, 2 -> worf)
UIWebView
and UIWebViewDelegate

let cred = URLCredential(trust: challenge.protectionSpace.serverTrust!)
completionHandler(.useCredential, cred)
}

A slight variation on the indexOf
method, if you need to filter multiple arrays:
function unique(item, index, array) {
return array.indexOf(item) == index;
}
Use as such:
arr.filter(unique);
Guided by Manitoba's post, I found another solution. As a summary, the solutions are:
With a USE command
USE mydb;
SELECT * FROM mytable
With an explicit schema prefix:
SELECT * FROM mydb.mytable
GUI
On Object Browser "SCHEMAS" pane, all database icons are initially not highlighted if you have the same issue. So you can right click on the database icon you wanted to be the default, select "Set as default schema".
Script snip below creates a pause sub that displayes the pause text in a string and waits for the Enter key. z can be anything. Great if multilple user intervention required pauses are needed. I just keep it in my standard script template.

WScript.Echo (strPause)
z = WScript.StdIn.Read(1)
End Sub
Try to use this code:
.col-lg-3 {
width: 100%;

margin: 0 auto;
}
if it didn't work use !important
The facebook like button does two things that the API does not do. This might create confusion when you compare the two.
If the URL you use in your like button has a redirect the button will actually show the count of the redirect URL versus the count of the URL you are using.
If the page has a og:url property the like button will show the likes of that url instead of the url in the browser.
Hope this helps someone
An alternative method is to create, but not throw, an Exception, and use that object from which to get the stack trace data, since the enclosing method will typically be at index 0 - as long as the JVM stores that information, as others have mentioned above. This not the cheapest method, however.
From Throwable.getStackTrace() (this has been the same since Java 5 at least):
The zeroth element of the array (assuming the array's length is non-zero) represents the top of the stack, which is the last method invocation in the sequence. Typically, this is the point at which this throwable was created and thrown.
The snippet below assumes the class is non-static (because of getClass()), but that's an aside.
System.out.printf("Class %s.%s\n", getClass().getName(), new Exception("is not thrown").getStackTrace()[0].getMethodName());
If I understand well, you want to Join ScheduleRequest
with User
and apply the in
clause to the userName
property of the entity User
.
I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join
part (because it handles the Join
logic outside the Criteria Query).
List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);
In order to write more type-safe code you could also use Metamodel by replacing this line:
Expression<String> exp = scheduleRequest.get("createdBy");
with this:
Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);
If it works, then you may try to add the Join
logic into the Criteria Query
. But right now I can't test it, so I prefer to see if somebody else wants to try.
Not a perfect answer though may be code snippets might help.
public <T> List<T> findListWhereInCondition(Class<T> clazz,
String conditionColumnName, Serializable... conditionColumnValues) {
QueryBuilder<T> queryBuilder = new QueryBuilder<T>(clazz);
addWhereInClause(queryBuilder, conditionColumnName,
conditionColumnValues);
queryBuilder.select();
return queryBuilder.getResultList();
}
private <T> void addWhereInClause(QueryBuilder<T> queryBuilder,
String conditionColumnName, Serializable... conditionColumnValues) {
Path<Object> path = queryBuilder.root.get(conditionColumnName);
In<Object> in = queryBuilder.criteriaBuilder.in(path);
for (Serializable conditionColumnValue : conditionColumnValues) {
in.value(conditionColumnValue);
}
queryBuilder.criteriaQuery.where(in);
}
Just add in the '0' in your select.

Proof of need for OnPropertyChanged("Count")
and OnPropertyChanged("Item[]")
calls in order to behave as per ObservableCollection
. Note that I don't know what the consequences are if you don't bother!
Here is a test method that shows that there are two PropertyChange events for each add in a normal observable collection. One for "Count"
and one for "Item[]"
.
[TestMethod]
public void TestAddSinglesInOldObsevableCollection()
{
int colChangedEvents = 0;
int propChangedEvents = 0;
var collection = new ObservableCollection<object>();
collection.CollectionChanged += (sender, e) => { colChangedEvents++; };
(collection as INotifyPropertyChanged).PropertyChanged += (sender, e) => { propChangedEvents++; };
collection.Add(new object());
collection.Add(new object());
collection.Add(new object());
Assert.AreEqual(3, colChangedEvents);
Assert.AreEqual(6, propChangedEvents);
}
@Shimmy , swap the standard for your collection and change to an add range and you will get zero PropertyChanges. Note that collection change does work fine, but not doing exactly what ObservableCollection does. So Test for shimmy collection looks like this:
[TestMethod]
public void TestShimmyAddRange()
{
int colChangedEvents = 0;
int propChangedEvents = 0;
var collection = new ShimmyObservableCollection<object>();
collection.CollectionChanged += (sender, e) => { colChangedEvents++; };
(collection as INotifyPropertyChanged).PropertyChanged += (sender, e) => { propChangedEvents++; };
collection.AddRange(new[]{
new object(), new object(), new object(), new object()}); //4 objects at once
Assert.AreEqual(1, colChangedEvents); //great, just one!
Assert.AreEqual(2, propChangedEvents); //fails, no events :(
}
FYI here is code from InsertItem (also called by Add) from ObservableCollection:
protected override void InsertItem(int index, T item)
{
base.CheckReentrancy();
base.InsertItem(index, item);
base.OnPropertyChanged("Count");
base.OnPropertyChanged("Item[]");
base.OnCollectionChanged(NotifyCollectionChangedAction.Add, item, index);
}

Here's a detailed explanation about the calculation of MaxClients and MaxRequestsPerChild
ServerLimit 16
StartServers 2
MaxClients 200
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
First of all, whenever an apache is started, it will start 2 child processes which is determined by StartServers
parameter. Then each process will start 25 threads determined by ThreadsPerChild
parameter so this means 2 process can service only 50 concurrent connections/clients i.e. 25x2=50. Now if more concurrent users comes, then another child process will start, that can service another 25 users. But how many child processes can be started is controlled by ServerLimit
parameter, this means that in the configuration above, I can have 16 child processes in total, with each child process can handle 25 thread, in total handling 16x25=400 concurrent users. But if number defined in MaxClients
is less which is 200 here, then this means that after 8 child processes, no extra process will start since we have defined an upper cap of MaxClients
. This also means that if I set MaxClients
to 1000, after 16 child processes and 400 connections, no extra process will start and we cannot service more than 400 concurrent clients even if we have increase the MaxClient
parameter. In this case, we need to also increase ServerLimit
to 1000/25 i.e. MaxClients/ThreadsPerChild=40
So this is the optmized configuration to server 1000 clients
<IfModule mpm_worker_module>
ServerLimit 40
StartServers 2
MaxClients 1000
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0
</IfModule>

This says it all. You have a mismatch between your key and certificate.
The modulus should match. Make sure you have correct key.
I set the content-type in the MarshallingView in the ContentNegotiatingViewResolver bean. It works easily, clean and smoothly:

<constructor-arg>
<bean class="org.springframework.oxm.xstream.XStreamMarshaller" />

</bean>
</list>
</property>
You could follow a solution similar to "How do I force “git pull” to overwrite local files?":
git fetch --all
git reset --hard origin/abranch
git checkout $branch
That would involve only one fetch.
With Git 2.23+, git checkout
is replaced here with git switch
(presented here) (still experimental).
git switch -f $branch
(with -f
being an alias for --discard-changes
, as noted in Jan's answer)
Proceed even if the index or the working tree differs from HEAD.
Both the index and working tree are restored to match the switching target.
The only way that cleanly solved this issue for me (.NET 4.6.1) was to not only add a Nuget reference to System.Net.Http V4.3.4 for the project that actually used System.Net.Http, but also to the startup project (a test project in my case).
(Which is strange, because the correct System.Net.Http.dll existed in the bin directory of the test project and the .config assemblyBingings looked OK, too.)
Spring allows you to do two things:
1. Autowiring
Usually in applicationContext.xml you define beans and other beans are wired using
constructor or setter methods. You can wire beans using XML or annotations.
In case you use annotations, you need to activate annotations and you have to add
<context:annotation-config />
in applicationContext.xml. This will simplify the
structure of the tag from applicationContext.xml, because you will not have to manually wire beans (constructor or setter). You can use @Autowire
annotation and the beans will be wired by type.
A step forward for escaping the manual XML configuration is
2. Autodiscovery
Autodiscovery is simplifying the XML one step further, in the sense that you don't even need too add the <bean>
tag in applicationContext.xml. You just mark the specific beans with one of the following annotation and Spring will automatically wire the marked beans and their dependencies into the Spring container. The annotations are as follow: @Controller, @Service, @Component, @Repository. By using <context:component-scan>
and pointing the base package, Spring will auto-discover and wire the components into Spring container.
As a conclusion:
<context:annotation-config />
is used in order to be able to use
@Autowired annotation<context:component-scan />
is used to determine the search of
specific beans and attempt of autowiring.How about:
return Pattern.matches("-?\\d+", input);
can use command:
:g/^/move 0

If the current directory is empty, you can do that with:
git clone git@github:me/name.git .
(Note the .
at the end to specify the current directory.) Of course, this also creates the .git
directory in your current folder, not just the source code from your project.
This optional [directory]
parameter is documented in the git clone
manual page, which points out that cloning into an existing directory is only allowed if that directory is empty.
For having hover effect you can simply try this code
import React from "react";
import "./styles.css";
export default function App() {
function MouseOver(event) {
event.target.style.background = 'red';
}
function MouseOut(event){
event.target.style.background="";
}
return (
<div className="App">
<button onMouseOver={MouseOver} onMouseOut={MouseOut}>Hover over me!</button>
</div>
);
}
Or if you want to handle this situation using useState() hook then you can try this piece of code
import React from "react";
import "./styles.css";
export default function App() {
let [over,setOver]=React.useState(false);
let buttonstyle={
backgroundColor:''
}
if(over){
buttonstyle.backgroundColor="green";
}
else{
buttonstyle.backgroundColor='';
}
return (
<div className="App">
<button style={buttonstyle}
onMouseOver={()=>setOver(true)}
onMouseOut={()=>setOver(false)}
>Hover over me!</button>
</div>
);
}
Both of the above code will work for hover effect but first procedure is easier to write and understand
Here is one common problem I haven't seen addressed in the other comments: is your host running a cache of some sort? If they are automatically caching results in some fashion you would get this sort of behavior.
The only thing that worked for me was creating a new application in the IIS, mapping it to exactly the same physical path, and changing only the authentication to be Anonymous.
Use the property TextWrapping
of the TextBlock
element:
<TextBlock Text="StackOverflow Forum"
Width="100"
TextWrapping="WrapWithOverflow"/>
You can also use indexValue attribute for passing multiple parameters via object:
var someData = "hello";
jQuery.ajax({
url: "http://maps.google.com/maps/api/js?v=3",
indexValue: {param1:someData, param2:"Other data 2", param3: "Other data 3"},
dataType: "script"
}).done(function() {
console.log(this.indexValue.param1);
console.log(this.indexValue.param2);
console.log(this.indexValue.param3);
});
You need to make sure that you add forward slash before your link to socket.io:
<script src="/socket.io/socket.io.js"></script>
Then in the view/controller just do:
var socket = io.connect()
That should solve your problem.
You have to look at the bigger problem. How to write the directives that solve one problem. You should try directive use-form-error. Would it help to solve this problem, and many others.
<form name="ExampleForm">
<label>Password</label>
<input ng-model="password" required />
<br>
<label>Confirm password</label>
<input ng-model="confirmPassword" required />
<div use-form-error="isSame" use-error-expression="password && confirmPassword && password!=confirmPassword" ng-show="ExampleForm.$error.isSame">Passwords Do Not Match!</div>
</form>

You are actually getting the correct value out.
The way your x86
(compatible) processor stores data like this, is in Little Endian order, meaning that, the MSB is last in your output.
So, given your output:
10101010
the last two hex values 10
are the Most Significant Byte (2 hex digits = 1 byte = 8 bits
(for (possibly unnecessary) clarification).
So, by reversing the memory storage order of the bytes, your value is actually: 01010101
.
Hope that clears it up!
This is because, the amount of memory you wish to assign for JVM is not available or may be you are assigning more than available memory. Try small size then u can see the difference.
Try:
set JAVA_OPTS=-Xms128m -Xmx512m -XX:PermSize=128m
A minimalistic example to quickly test the TTS system:
private TextToSpeech textToSpeechSystem;
@Override
protected void onStart() {
super.onStart();
textToSpeechSystem = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
String textToSay = "Hello world, this is a test message!";
textToSpeechSystem.speak(textToSay, TextToSpeech.QUEUE_ADD, null);
}
}
});
}
If you don't use localized messages textToSpeechSystem.setLanguage(..)
is important as well, since your users probably don't all have English set as their default language so the pronunciation of the words will be wrong. But for testing TTS in general this snippet is enough

For higher performance, I recommend this:
var select = document.getElementById("year");
var options = [];
var option = document.createElement('option');
//for (var i = 2011; i >= 1900; --i)
for (var i = 1900; i < 2012; ++i)
{
//var data = '<option value="' + escapeHTML(i) +'">" + escapeHTML(i) + "</option>';
option.text = option.value = i;
options.push(option.outerHTML);
}
select.insertAdjacentHTML('beforeEnd', options.join('\n'));
This avoids a redraw after each appendChild, which speeds up the process considerably, especially for a larger number of options.
Optional for generating the string by hand:
function escapeHTML(str)
{
var div = document.createElement('div');
var text = document.createTextNode(str);
div.appendChild(text);
return div.innerHTML;
}
However, I would not use these kind of methods at all.
It seems crude. You best do this with a documentFragment:
var docfrag = document.createDocumentFragment();
for (var i = 1900; i < 2012; ++i)
{
docfrag.appendChild(new Option(i, i));
}
var select = document.getElementById("year");
select.appendChild(docfrag);
module Amimal
module Herbivorous
EATER="plants"
end
end
Amimal::Herbivorous::EATER => "plants"
:: Is used to create a scope . In order to access Constant EATER from 2 modules we need to scope the modules to reach up to the constant
I don't know why this old issue popped up today in the Bash tagged listings, but just in case for future researchers, keep in mind that you can avoid escaping by using ASCII codes of the chars you need to echo.
Example:
echo -e "This is \x22\x27\x22\x27\x22text\x22\x27\x22\x27\x22"
This is "'"'"text"'"'"
\x22
is the ASCII code (in hex) for double quotes and \x27
for single quotes. Similarly you can echo any character.
I suppose if we try to echo the above string with backslashes, we will need a messy two rows backslashed echo... :)
For variable assignment this is the equivalent:
$ a=$'This is \x22text\x22'
$ echo "$a"
This is "text"
If the variable is already set by another program, you can still apply double/single quotes with sed or similar tools.
Example:
$ b="Just another text here"
$ echo "$b"
Just another text here
$ sed 's/text/"'\0'"/' <<<"$b" #\0 is a special sed operator
Just another "0" here #this is not what i wanted to be
$ sed 's/text/\x22\x27\0\x27\x22/' <<<"$b"
Just another "'text'" here #now we are talking. You would normally need a dozen of backslashes to achieve the same result in the normal way.
If you are creating custom Layout for alert dialog
then you may add like this way easily to change the color
<LinearLayout
android:id="@+id/DialogTitleBorder"
android:layout_width="fill_parent"
android:layout_height="1dip"
android:layout_below="@id/mExitDialogDesc"
android:background="#4BBAE3" <!--change color easily -->
>
</LinearLayout>
Another "trick" for generating the column list is simply to drag the "Columns" node from Object Explorer onto a query window.
This one works:
cd /usr/local/bin/
ls -l /usr/local/bin | grep '../Library/Frameworks/Python.framework/Versions/2.7' | awk '{print $9}' | tr -d @ | xargs rm
Description:
It list all the links, removes @
character and then removes them.
The <ul>
is by default a block element, make it inline-block
instead:
.navigation-bar ul {
padding: 0px;
margin: 0px;
text-align: center;
display:inline-block;
vertical-align:top;
}
There is no difference between the two in how they are stored in memory and registers, there is no signed and unsigned version of int registers there is no signed info stored with the int, the difference only becomes relevant when you perform maths operations, there are signed and unsigned version of the maths ops built into the CPU and the signedness tell the compiler which version to use.

If you're printing to stdout, it depends on the terminal you're printing to. You can use ansi escape codes on xterms and other similar terminal emulators. Here's a bash code snippet that will print all 255 colors supported by xterm, putty and Konsole:
for ((i=0;i<256;i++)); do echo -en "\e[38;5;"$i"m"$i" "; done
You can use these escape codes in any programming language. It's better to rely on a library that will decide which codes to use depending on architecture and the content of the TERM environment variable.
CSS for IE10+ and IE9

If you aren't comfortable with using negative margins, check this out.
div {
position: fixed;
left: 50%;
bottom: 20px;
transform: translate(-50%, -50%);
margin: 0 auto;
}
<div>
Your Text
</div>
Especially useful when you don't know the width of the div.
align="center"
has no effect.
Since you have position:absolute
, I would recommend positioning it 50% from the left and then subtracting half of its width from its left margin.
#manipulate {
position:absolute;
width:300px;
height:300px;
background:#063;
bottom:0px;
right:25%;
left:50%;
margin-left:-150px;
}
We can use concurrent collection classes to avoid ConcurrentModificationException while iterating over a collection, for example CopyOnWriteArrayList instead of ArrayList.

I suggest you do it a different way.
In the following code I set as a Range
the column with the sports name F and loop through each cell of it, check if it is "hockey" and if yes I insert the values in the other sheet one by one, by using Offset.
I do not think it is very complicated and even if you are just learning VBA, you should probably be able to understand every step. Please let me know if you need some clarification
Sub TestThat()
'Declare the variables
Dim DataSh As Worksheet
Dim HokySh As Worksheet
Dim SportsRange As Range
Dim rCell As Range
Dim i As Long
'Set the variables
Set DataSh = ThisWorkbook.Sheets("Data")
Set HokySh = ThisWorkbook.Sheets("Hoky")
Set SportsRange = DataSh.Range(DataSh.Cells(3, 6), DataSh.Cells(Rows.Count, 6).End(xlUp))
'I went from the cell row3/column6 (or F3) and go down until the last non empty cell
i = 2
For Each rCell In SportsRange 'loop through each cell in the range
If rCell = "hockey" Then 'check if the cell is equal to "hockey"
i = i + 1 'Row number (+1 everytime I found another "hockey")
HokySh.Cells(i, 2) = i - 2 'S No.
HokySh.Cells(i, 3) = rCell.Offset(0, -1) 'School
HokySh.Cells(i, 4) = rCell.Offset(0, -2) 'Background
HokySh.Cells(i, 5) = rCell.Offset(0, -3) 'Age

As the compiler says, grid
was not declared in the scope of your function :) "Scope" basically means a set of curly braces. Every variable is limited to the scope in which it is declared (it cannot be accessed outside that scope). In your case, you're declaring the grid
variable in your main()
function and trying to use it in nonrecursivecountcells()
. You seem to be passing it as the argument colors
however, so I suggest you just rename your uses of grid
in nonrecursivecountcells()
to colors
. I think there may be something wrong with trying to pass the array that way, too, so you should probably investigate passing it as a pointer (unless someone else says something to the contrary).
I've been able to trap them with jQuery:
$(document).keypress(function (eventObject) {
alert(eventObject.keyCode);
});
An example: http://jsfiddle.net/AjKjU/
The below is what I have used i the past to accomplish the need for a Scalar UDF in MS SQL:
IF OBJECT_ID('tempdb..##fn_Divide') IS NOT NULL DROP PROCEDURE ##fn_Divide
GO
CREATE PROCEDURE ##fn_Divide (@Numerator Real, @Denominator Real) AS
BEGIN
SELECT Division =
CASE WHEN @Denominator != 0 AND @Denominator is NOT NULL AND @Numerator != 0 AND @Numerator is NOT NULL THEN
@Numerator / @Denominator
ELSE
0
END
RETURN
END
GO
Exec ##fn_Divide 6,4
This approach which uses a global variable for the PROCEDURE allows you to make use of the function not only in your scripts, but also in your Dynamic SQL needs.
For those who are looking for the fastest way to iterate over strings in php, Ive prepared a benchmark testing.
The first method in which you access string characters directly by specifying its position in brackets and treating string like an array:
$string = "a sample string for testing";
$char = $string[4] // equals to m
I myself thought the latter is the fastest method, but I was wrong.
As with the second method (which is used in the accepted answer):
$string = "a sample string for testing";
$string = str_split($string);
$char = $string[4] // equals to m
This method is going to be faster cause we are using a real array and not assuming one to be an array.
Calling the last line of each of the above methods for 1000000
times lead to these benchmarking results:
Using string[i]
0.24960017204285 Seconds
Using str_split
0.18720006942749 Seconds
Which means the second method is way faster.
After INSERT
query you can use ROW_COUNT()
to check for successful insert operation as:
SELECT IF(ROW_COUNT() = 1, "Insert Success", "Insert Failed") As status;
It depends which style from the div you need. Is this a background style which was defined in CSS
or background style which was added through javascript(inline)
to the current node?
In case of CSS
style, you should use computed style. Like you do in getStyle()
.
With inline style you should use node.style
reference: x.style.backgroundColor
;
Also notice, that you pick the style by using camelCase/non hyphen reference, so not background-color
, but backgroundColor
;
Leaving this here for myself,
If I get this error, I probably used const char*
when I should be using char* const
.
This makes the pointer constant, and not the contents of the string.
const char* const
makes it so the value and the pointer is constant also.
I had the same problem. my problem was that the version of the dependency had conflict with the elasticsearch version. check the version in ip:9200 and use the dependency version that match it
The ~30th answer :-)
In VS2015:
In my case, doing it step-by-step helped discovered what my problem is without all those errors thrown left and right.
If you had to know, I added Entity Framework (EF) 6.1.3 via NuGet when the project was set for .NET 4.5.2. I later downgraded the .NET Framework down to 4, and then the error was more obvious. Via NuGet, I uninstalled EF and re-added it.
You could use extension methods to make it a little more readable:
public static class DateTimeExtensions
{
public static bool InRange(this DateTime dateToCheck, DateTime startDate, DateTime endDate)
{
return dateToCheck >= startDate && dateToCheck < endDate;
}
}
Now you can write:
dateToCheck.InRange(startDate, endDate)
Seems there's an easier way, at least in Kendo UI v2015.2.624:
$('#myDropDownSelector').data('kendoDropDownList').search('Text value to find');
If there's not a match in the dropdown, Kendo appears to set the dropdown to an unselected value, which makes sense.
I couldn't get @Gang's answer to work, but if you swap his value
with search
, as above, we're golden.

I got solution after working whole day on it. It is little hacky solution Added span inside td tag

Date format which Im using is dd/MM/YYYY. Tested in Datatables1.9.0
It looks like Microsoft has deprecated lots of calls which use buffers to improve code security. However, the solutions they're providing aren't portable. Anyway, if you aren't interested in using the secure version of their calls (like fopen_s), you need to place a definition of _CRT_SECURE_NO_DEPRECATE before your included header files. For example:
#define _CRT_SECURE_NO_DEPRECATE
#include <stdio.h>
The preprocessor directive can also be added to your project settings to effect it on all the files under the project. To do this add _CRT_SECURE_NO_DEPRECATE to Project Properties -> Configuration Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions.
If you have to choose between __repr__
or __str__
go for the first one, as by default implementation __str__
calls __repr__
when it wasn't defined.
Custom Vector3 example:
class Vector3(object):
def __init__(self, args):
self.x = args[0]
self.y = args[1]
self.z = args[2]
def __repr__(self):
return "Vector3([{0},{1},{2}])".format(self.x, self.y, self.z)
def __str__(self):
return "x: {0}, y: {1}, z: {2}".format(self.x, self.y, self.z)
In this example, repr
returns again a string that can be directly consumed/executed, whereas str
is more useful as a debug output.
v = Vector3([1,2,3])
print repr(v) #Vector3([1,2,3])
print str(v) #x:1, y:2, z:3
Without to much modifications of the original code, it could become :
while (!iFile.eof())
{
int x;
iFile >> x;
if (!iFile.eof()) break;
cerr << x << endl;
}
but I prefer the two other solutions above in general.
BrixenDK is right.
.ajaxStop()
callback executed when all ajax call completed. This is a best place to put your handler.
$(document).ajaxStop(function(){
window.location.reload();
});
Here's a very good explanation taken verbatim from http://www.paulboxley.com/blog/2011/06/git-caret-and-tilde :
ref~
is shorthand forref~1
and means the commit's first parent.ref~2
means the commit's first parent's first parent.ref~3
means the commit's first parent's first parent's first parent. And so on.
ref^
is shorthand forref^1
and means the commit's first parent. But where the two differ is thatref^2
means the commit's second parent (remember, commits can have two parents when they are a merge).The
^
and~
operators can be combined.
You need to set basicHttpBinding -> MaxReceivedMessageSize in the client configuration.
This is now available for free in twig templates (tested on sf2 version 2.0.14)
{{ app.request.getBaseURL() }}
In later Symfony versions (tested on 2.5), try :
{{ app.request.getSchemeAndHttpHost() }}
I'll give you another solution, Make your lambda invoke a function.
def multiple_statements(x, y):
print('hi')
print('there')
print(x)
print(y)
return 1
junky = lambda x, y: multiple_statements(x, y)
junky('a', 'b');
this bellow solution worked for me
$result_encr="##Sƒ";

android:pivotY="50%"
android:fromDegrees="0"

<gradient
android:type="sweep"
android:useLevel="false"
android:startColor="#447a29"
android:endColor="#00ffffff"
android:angle="0"/>

If you're using fs-extra, you can skip the JSON.stringify
part with the writeJson function:
const fsExtra = require('fs-extra');
fsExtra.writeJson('./package.json', {name: 'fs-extra'})
.then(() => {
console.log('success!')
})
.catch(err => {
console.error(err)
})
best and simple way is to put title inside a span and replace then.
'<div id="'+div_id+'" class="widget" style="height:60px;width:110px">\n\
<div class="widget-head ui-widget-header"
style="cursor:move;height:20px;width:130px">'+
'<span id="'+span_id+'" style="float:right; cursor:pointer"
class="dialog_link ui-icon ui-icon-newwin ui-icon-pencil"></span>' +
'<span id="spTitle">'+
dialog_title+ '</span>'
'</div></div>
now you can simply use this:
$('#'+div_id+' .widget-head sp#spTitle').text("new dialog title");
There is a sorting algorithm in the standard library, in the header <algorithm>
. It sorts inplace, so if you do the following, your original word will become sorted.
std::sort(word.begin(), word.end());
If you don't want to lose the original, make a copy first.
std::string sortedWord = word;
std::sort(sortedWord.begin(), sortedWord.end());
Probably you did not fetch the remote changes before the rebase or someone pushed new changes (while you were rebasing and trying to push). Try these steps:
#fetching remote 'feature/my_feature_branch' branch to the 'tmp' local branch
git fetch origin feature/my_feature_branch:tmp
#rebasing on local 'tmp' branch
git rebase tmp
#pushing local changes to the remote
git push origin HEAD:feature/my_feature_branch
#removing temporary created 'tmp' branch
git branch -D tmp
if you're looking for the equivalent of "adb run myapp.apk"
you can use the script shown in this answer
(linux and mac only - maybe with cygwin on windows)
linux/mac users can also create a script to run an apk with something like the following:
create a file named "adb-run.sh" with these 3 lines:
pkg=$(aapt dump badging $1|awk -F" " '/package/ {print $2}'|awk -F"'" '/name=/ {print $2}')
act=$(aapt dump badging $1|awk -F" " '/launchable-activity/ {print $2}'|awk -F"'" '/name=/ {print $2}')
adb shell am start -n $pkg/$act
then "chmod +x adb-run.sh" to make it executable.
now you can simply:
adb-run.sh myapp.apk
The benefit here is that you don't need to know the package name or launchable activity name. Similarly, you can create "adb-uninstall.sh myapp.apk"
Note: This requires that you have aapt in your path. You can find it under the new build tools folder in the SDK

You should be able to do this with JavaScript:
<input type="button" value="Click Me!" onclick="submitForms()" />
If your forms have IDs:
submitForms = function(){
document.getElementById("form1").submit();
document.getElementById("form2").submit();
}
If your forms don't have IDs but have names:
submitForms = function(){
document.forms["form1"].submit();
document.forms["form2"].submit();

I use Enthought Canopy for my python, at first I used "pip install --upgrade pip", it showed a syntax error like yours, then I added a "!" in front of the pip, then it finally worked.
I used http://codingbat.com/ . A great website that not only takes one answer, like Project Euler, but also checks your code for more robustness by running it through multiple tests. It asks for much broader code than Project Euler, but its also much simpler than most Euler problems. It also has progress graphs which are pretty cool.
First one will create new String object in heap and str will refer it. In addition literal will also be placed in String pool. It means 2 objects will be created and 1 reference variable.
Second option will create String literal in pool only and str will refer it. So only 1 Object will be created and 1 reference. This option will use the instance from String pool always rather than creating new one each time it is executed.
Oracle does not have a simple database model like MySQL or MS SQL Server. I find the closest thing is to query the tablespaces and the corresponding users within them.
For example, I have a DEV_DB tablespace with all my actual 'databases' within them:
SQL> SELECT TABLESPACE_NAME FROM USER_TABLESPACES;
Resulting in:
SYSTEM SYSAUX UNDOTBS1 TEMP USERS EXAMPLE DEV_DB
It is also possible to query the users in all tablespaces:
SQL> select USERNAME, DEFAULT_TABLESPACE from DBA_USERS;
Or within a specific tablespace (using my DEV_DB tablespace as an example):
SQL> select USERNAME, DEFAULT_TABLESPACE from DBA_USERS where DEFAULT_TABLESPACE = 'DEV_DB';
ROLES DEV_DB
DATAWARE DEV_DB

The quick answer on how to prevent it is that you most likely need to stop JBoss before starting it again.
You should be able to call the "Terminate" button in the Console view to shutdown the server.
I would prevent loops in general if i can, set approaches are much more efficient:
INSERT INTO tblFoo
SELECT TOP (300) n = ROW_NUMBER()OVER (ORDER BY [object_id])
FROM sys.all_objects ORDER BY n;
From MSDN:
Use of two sequential underscore characters ( __ ) at the beginning of an identifier, or a single leading underscore followed by a capital letter, is reserved for C++ implementations in all scopes. You should avoid using one leading underscore followed by a lowercase letter for names with file scope because of possible conflicts with current or future reserved identifiers.
This means that you can use a single underscore as a member variable prefix, as long as it's followed by a lower-case letter.
This is apparently taken from section 17.4.3.1.2 of the C++ standard, but I can't find an original source for the full standard online.

An initial

Shell scripts, no matter how they are executed, execute one command after the other. So your code will execute results.sh
after the last command of st_new.sh
has finished.
Now there is a special command which messes this up: &
cmd &
means: "Start a new background process and execute cmd
in it. After starting the background process, immediately continue with the next command in the script."
That means &
doesn't wait for cmd
to do it's work. My guess is that st_new.sh
contains such a command. If that is the case, then you need to modify the script:
cmd &
BACK_PID=$!
This puts the process ID (PID) of the new background process in the variable BACK_PID
. You can then wait for it to end:
while kill -0 $BACK_PID ; do
echo "Process is still active..."
sleep 1
# You can add a timeout here if you want
done
or, if you don't want any special handling/output simply
wait $BACK_PID
Note that some programs automatically start a background process when you run them, even if you omit the &
. Check the documentation, they often have an option to write their PID to a file or you can run them in the foreground with an option and then use the shell's &
command instead to get the PID.
I suppose you don't want your textarea-content to be parsed as HTML. In this case, you can just set it as plaintext so the browser doesn't treat it as HTML and doesn't remove newlines No CSS or preprocessing required.

Try this on for size:
String properCase (String inputVal) {
// Empty strings should be returned as-is.
if (inputVal.length() == 0) return "";
// Strings with only one character uppercased.
if (inputVal.length() == 1) return inputVal.toUpperCase();
// Otherwise uppercase first letter, lowercase the rest.
return inputVal.substring(0,1).toUpperCase()
+ inputVal.substring(1).toLowerCase();
}
It basically handles special cases of empty and one-character string first and correctly cases a two-plus-character string otherwise. And, as pointed out in a comment, the one-character special case isn't needed for functionality but I still prefer to be explicit, especially if it results in fewer useless calls, such as substring to get an empty string, lower-casing it, then appending it as well.

Answers by ‘smartnut007’, ‘Bill Karwin’, and ‘sqlvogel’ are excellent. Yet let me put an interesting perspective to it.
Well, we have prime and non-prime keys.
When we focus on how non-primes depend on primes, we see two cases:
Non-primes can be dependent or not.
When not dependent: there can be no-dependency or transitive dependency
What about dependencies among primes?
Now you see, we’re not addressing the dependency relationship among primes by either 2nd or 3rd NF. Further such dependency, if any, is not desirable and thus we’ve a single rule to address that. This is BCNF.
Referring to the example from Bill Karwin's post here, you’ll notice that both ‘Topping’, and ‘Topping Type’ are prime keys and have a dependency. Had they been non-primes with dependency, then 3NF would have kicked in.
Note:
The definition of BCNF is very generic and without differentiating attributes between prime and non-prime. Yet, the above way of thinking helps to understand how some anomaly is percolated even after 2nd and 3rd NF.
Advanced Topic: Mapping generic BCNF to 2NF & 3NF
Now that we know BCNF provides a generic definition without reference to any prime/non-prime attribues, let's see how BCNF and 2/3 NF's are related.
First, BCNF requires (other than the trivial case) that for each functional dependency
For case (1), 3NF takes care of.
For case (3), 2NF takes care of.
For case (2), we find the use of BCNFX -> Y
(FD), X should be super-key.
If you just consider any FD, then we've three cases - (1) Both X and Y non-prime, (2) Both prime and (3) X prime and Y non-prime, discarding the (nonsensical) case X non-prime and Y prime.
To enable your app to listen for both http
and https
on ports 80
and 443
respectively, do the following
Create an express app:
var express = require('express');
var app = express();
The app returned by express()
is a JavaScript function. It can be be passed to Node’s HTTP servers as a callback to handle requests. This makes it easy to provide both HTTP and HTTPS versions of your app using the same code base.
You can do so as follows:
var express = require('express');
var https = require('https');
var http = require('http');
var fs = require('fs');
var app = express();
var options = {
key: fs.readFileSync('/path/to/key.pem'),
cert: fs.readFileSync('/path/to/cert.pem')
};
http.createServer(app).listen(80);
https.createServer(options, app).listen(443);

Open 'postgresql.conf' in you favourite editor. Look for the variable 'unix_socket_directories', it will most likely look like this:
unix_socket_directories = '/private/tmp/'
Change the line to this:
unix_socket_directories = '/var/pgsql_socket/'
Note if you want the socket files in more than one directory comma separate them.
You can't do pointer arithmetic on void *
types, for exactly this reason!
$ cd "$DOCS"
You need to quote "$DOCS"
to prevent spaces from being parsed as word separators. More often than not, variable references should be quoted.
Note that $HOME
would have the same problem. The issue is coming from when the shell evaluates variable references; it's nothing to do with what variables you use or how you assign to them. It's the expansion that needs to be quoted.
$ echo $HOME
/home/my dir
This is deceptive. echo
is actually echoing the two strings /home/my
and dir
. If you use cd
or ls
you'll see how it's actually working.
$ ls $HOME
ls: cannot access /home/my: No such file or directory
ls: cannot access dir: No such file or directory
$ cd $HOME
bash: cd: /home/my: No such file or directory
$ cd "$HOME"
<success!>
Can I ask why it works when I manually type it in but not in a variable?
Great question! Let's examine the commands you typed:
$ DOCS="\"/cygdrive/c/Users/my dir/Documents\""
$ echo $DOCS
"/cygdrive/c/Users/my dir/Documents"
$ cd $DOCS
-bash: cd: "/cygdrive/c/Users/my: No such file or directory
The reason this doesn't work is because Bash doesn't parse quotes inside variable expansions. It does perform word splitting, so whitespace in unquoted variable expansions is taken as word separators. It doesn't parse quotes in any way, meaning you can't put double quotes inside a variable to override word splitting.
$ cd $DOCS
Because of this, cd
is passed two parameters. As far as cd
knows it looks like you wrote:
$ cd '"/cygdrive/c/Users/my' 'dir/Documents"'
Two parameters, with double quotes intact.
A similar code I once wrote to remove strings not starting with SB.1 from an array of strings
my @adoSymbols=('SB.1000','RT.10000','PC.10000');
##Remove items from an array from backward
for(my $i=$#adoSymbols;$i>=0;$i--) {
unless ($adoSymbols[$i] =~ m/^SB\.1/) {splice(@adoSymbols,$i,1);}
}
You need to try one of the following:
They offer many more features and will be easier to get what you are looking for.
I prefer to use
<input type='date' id='hasta' value='<?php echo date('Y-m-d');?>'>
that works well
Use only one server side form tag.
Check your Master page for <form runat="server">
- there should be only one.
Why do you need more than one?
I recommend just disabling this rule in Sonar, there is no real benefit of introducing a private constructor, just redundant characters in your codebase other people need to read and computer needs to store and process.
The last index of a C-String is always the integer value 0, hence the phrase "null terminated string". Since integer 0 is the same as the Boolean value false in C, you can use that to make a simple while clause for your for loop. When it hits the last index, it will find a zero and equate that to false, ending the for loop.
for(int i = 0; string[i]; i++) { printf("Char at position %d is %c\n", i, string[i]); }
Step-by-Step way to do this:
We just store the enum name itself - it's more readable.
We did mess around with storing specific values for enums where there are a limited set of values, e.g., this enum that has a limited set of statuses that we use a char to represent (more meaningful than a numeric value):
public enum EmailStatus {
EMAIL_NEW('N'), EMAIL_SENT('S'), EMAIL_FAILED('F'), EMAIL_SKIPPED('K'), UNDEFINED('-');
private char dbChar = '-';
EmailStatus(char statusChar) {
this.dbChar = statusChar;
}
public char statusChar() {
return dbChar;
}
public static EmailStatus getFromStatusChar(char statusChar) {
switch (statusChar) {
case 'N':
return EMAIL_NEW;
case 'S':
return EMAIL_SENT;
case 'F':
return EMAIL_FAILED;
case 'K':
return EMAIL_SKIPPED;
default:
return UNDEFINED;
}
}
}
and when you have a lot of values you need to have a Map inside your enum to keep that getFromXYZ method small.
Good news! awk
field separator can be a regular expression. You just need to use -F"<separator1>|<separator2>|..."
:
awk -F"/|=" -vOFS='\t' '{print $3, $5, $NF}' file
Returns:
tc0001 tomcat7.1 demo.example.com
tc0001 tomcat7.2 quest.example.com
tc0001 tomcat7.5 www.example.com
Here:
-F"/|="
sets the input field separator to either /
or =
. Then, it sets the output field separator to a tab.
-vOFS='\t'
is using the -v
flag for setting a variable. OFS
is the default variable for the Output Field Separator and it is set to the tab character. The flag is necessary because there is no built-in for the OFS like -F
.
{print $3, $5, $NF}
prints the 3rd, 5th and last fields based on the input field separator.
See another example:
$ cat file
hello#how_are_you
i#am_very#well_thank#you
This file has two fields separators, #
and _
. If we want to print the second field regardless of the separator being one or the other, let's make both be separators!
$ awk -F"#|_" '{print $2}' file
how
am
Where the files are numbered as follows:
hello#how_are_you i#am_very#well_thank#you
^^^^^ ^^^ ^^^ ^^^ ^ ^^ ^^^^ ^^^^ ^^^^^ ^^^
1 2 3 4 1 2 3 4 5 6

Sorry to reopen an old question, but since it was edited recently saying that the "issue" still remains in Java 11, I felt like I wanted to point out this:
answerList
.stream()
.collect(Collectors.toMap(Answer::getId, Answer::getAnswer));
gives you the null pointer exception because the map does not allow null as a value.
This makes sense because if you look in a map for the key k
and it is not present, then the returned value is already null
(see javadoc). So if you were able to put in k
the value null
, the map would look like it's behaving oddly.
As someone said in the comments, it's pretty easy to solve this by using filtering:
answerList
.stream()
.filter(a -> a.getAnswer() != null)
.collect(Collectors.toMap(Answer::getId, Answer::getAnswer));
in this way no null
values will be inserted in the map, and STILL you will get null
as the "value" when looking for an id that does not have an answer in the map.
I hope this makes sense to everyone.
If we have built in functions to convert your integer values to COLOR then why to worry.
string hexValue = string.Format("{0:X}", intColor);
Color brushes = System.Drawing.ColorTranslator.FromHtml("#"+hexValue);
It's actually the JavaScript array reduce
function rather than being something specific to TypeScript.
As described in the docs: Apply a function against an accumulator and each value of the array (from left-to-right) as to reduce it to a single value.
Here's an example which sums up the values of an array:
let total = [0, 1, 2, 3].reduce((accumulator, currentValue) => accumulator + currentValue);_x000D_
console.log(total);
_x000D_

Contrary to some answers posted in this thread, adding 'DIRS': ['templates']
has no effect(it's redundant) since templates
is the default path where Django looks for templates.
If you are attempting to reference an app's template, ensure that your app is in the list of INSTALLED_APPS
in the main project settings.py
.
INSTALLED_APPS': [
# ...
'my_app',
]
Quoting Django's Templates documentation:
class DjangoTemplates¶
Set BACKEND to 'django.template.backends.django.DjangoTemplates' to configure a Django template engine.
When APP_DIRS is True, DjangoTemplates engines look for templates in the templates subdirectory of installed applications. This generic name was kept for backwards-compatibility.
When you create an application to your project, there's no templates
directory inside the application directory. Since that you can have an application without using templates, Django doesn't create such directory. That is, you have to create it and storing your templates in there.
Here's another paragraph from Django Tutorial documentation, which is even clearer:
Your project’s TEMPLATES setting describes how Django will load and render templates. The default settings file configures a DjangoTemplates backend whose APP_DIRS option is set to True. By convention DjangoTemplates looks for a “templates” subdirectory in each of the INSTALLED_APPS.

Just discovered GenMyModel, an awesome UML modeler to design class diagram online
Although the answer I originally marked as chosen is correct and achieves what I asked there is a better way of doing this (which others acknowledged but didn't go into). A composite unique index should be created on the table consisting of fund_id
and date
.
ALTER TABLE funds ADD UNIQUE KEY `fund_date` (`fund_id`, `date`);
Then when inserting a record add the condition when a conflict is encountered:
INSERT INTO funds (`fund_id`, `date`, `price`)
VALUES (23, DATE('2013-02-12'), 22.5)
ON DUPLICATE KEY UPDATE `price` = `price`; --this keeps the price what it was (no change to the table) or:
INSERT INTO funds (`fund_id`, `date`, `price`)
VALUES (23, DATE('2013-02-12'), 22.5)
ON DUPLICATE KEY UPDATE `price` = 22.5; --this updates the price to the new value
This will provide much better performance to a sub-query and the structure of the table is superior. It comes with the caveat that you can't have NULL values in your unique key columns as they are still treated as values by MySQL.
Because the condition is never true.
i.e. count !=100 never executes when you put count=count+3 or count =count+9.
try this out..while count<100
To fill a list with seperate instances of a class, you can use a for loop in the declaration of the list. The * multiply will link each copy to the same instance.
instancelist = [ MyClass() for i in range(29)]
and then access the instances through the index of the list.
instancelist[5].attr1 = 'whamma'

Case # 1: Save the model to use it yourself for inference: You save the model, you restore it, and then you change the model to evaluation mode. This is done because you usually have BatchNorm
and Dropout
layers that by default are in train mode on construction:
torch.save(model.state_dict(), filepath)
#Later to restore:
model.load_state_dict(torch.load(filepath))
model.eval()
Case # 2: Save model to resume training later: If you need to keep training the model that you are about to save, you need to save more than just the model. You also need to save the state of the optimizer, epochs, score, etc. You would do it like this:
state = {
'epoch': epoch,
'state_dict': model.state_dict(),
'optimizer': optimizer.state_dict(),
...
}
torch.save(state, filepath)
To resume training you would do things like: state = torch.load(filepath)
, and then, to restore the state of each individual object, something like this:
model.load_state_dict(state['state_dict'])
optimizer.load_state_dict(state['optimizer'])
Since you are resuming training, DO NOT call model.eval()
once you restore the states when loading.
Case # 3: Model to be used by someone else with no access to your code:
In Tensorflow you can create a .pb
file that defines both the architecture and the weights of the model. This is very handy, specially when using Tensorflow serve
. The equivalent way to do this in Pytorch would be:
torch.save(model, filepath)
# Then later:
model = torch.load(filepath)
This way is still not bullet proof and since pytorch is still undergoing a lot of changes, I wouldn't recommend it.
You can't do it with only one git command but you can automate it with one bash line.
To safely update all branches with one line, here is what I do:
git fetch --all && for branch in $(git branch | sed '/*/{$q;h;d};$G' | tr -d '*') ; do git checkout $branch && git merge --ff-only || break ; done
If it can't fast-forward one branch or encounter an error, it will stop and leave you in that branch so that you can take back control and merge manually.
If all branches can be fast-forwarded, it will end with the branch you were currently in, leaving you where you were before updating.
Explanations:
For a better readability, it can be split over several lines:
git fetch --all && \
for branch in $(git branch | sed '/*/{$q;h;d};$G' | tr -d '*')
do git checkout $branch && \
git merge --ff-only || break
done
git fetch --all && ...
=> Fetches all refs from all remotes and continue with the next command if there has been no error.
git branch | sed '/*/{$q;h;d};$G' | tr -d '*'
=> From the output of git branch
, sed
take the line with a *
and move it to the end (so that the current branch will be updated last). Then tr
simply remove the *
.
for branch in $(...) ; do git checkout $branch && git merge --ff-only || break ; done
= > For each branch name obtained from the previous command, checkout this branch and try to merge with a fast-forward. If it fails, break
is called and the command stops here.
Of course, you can replace git merge --ff-only
with git rebase
if it is what you want.
Finally, you can put it in your bashrc as an alias:
alias git-pull-all='git fetch --all && for branch in $(git branch | sed '\''/*/{$q;h;d};$G'\'' | tr -d "*") ; do git checkout $branch && git merge --ff-only || break ; done'
Or if you are afraid of messing up with the ' and ", or you simply prefer to keep syntactic readability in your editor, you can declare it as a function:
git-pull-all()
{
git fetch --all && for branch in $(git branch | sed '/*/{$q;h;d};$G' | tr -d '*') ; do git checkout $branch && git merge --ff-only || break ; done
}
Bonus:
For those who'd like the explanation on the sed '/*/{$q;h;d};$G'
part:
/*/
=> Search for the line with a *
.
{$q
=> If it is in the last line, quit (we don't need to do anything because the current branch is already the last one in the list).
;h;d}
=> Otherwise, store the line in the hold buffer and delete it in the current list position.
;$G
=> When it reaches the last line, append the content of the hold buffer.
You could make a little Tkinter app:
import Tkinter as tk
def onKeyPress(event):
text.insert('end', 'You pressed %s\n' % (event.char, ))
root = tk.Tk()
root.geometry('300x200')
text = tk.Text(root, background='black', foreground='white', font=('Comic Sans MS', 12))
text.pack()
root.bind('<KeyPress>', onKeyPress)
root.mainloop()
export function stringFormate (str: string, ...args: string[]) {
return args.reduce((acc, curr, i) => acc.replace(new RegExp("\\{" + i + "\\}", 'g'), curr), str);
}
You can't rewrite a line without rewriting the entire file (unless the lines happen to be the same length). If your files are small then reading the entire target file into memory and then writing it out again might make sense. You can do that like this:
using System;
using System.IO;
class Program
{
static void Main(string[] args)
{
int line_to_edit = 2; // Warning: 1-based indexing!
string sourceFile = "source.txt";
string destinationFile = "target.txt";
// Read the appropriate line from the file.
string lineToWrite = null;
using (StreamReader reader = new StreamReader(sourceFile))
{
for (int i = 1; i <= line_to_edit; ++i)
lineToWrite = reader.ReadLine();
}
if (lineToWrite == null)
throw new InvalidDataException("Line does not exist in " + sourceFile);
// Read the old file.
string[] lines = File.ReadAllLines(destinationFile);
// Write the new file over the old file.
using (StreamWriter writer = new StreamWriter(destinationFile))
{
for (int currentLine = 1; currentLine <= lines.Length; ++currentLine)
{
if (currentLine == line_to_edit)
{
writer.WriteLine(lineToWrite);
}
else
{
writer.WriteLine(lines[currentLine - 1]);
}
}
}
}
}
If your files are large it would be better to create a new file so that you can read streaming from one file while you write to the other. This means that you don't need to have the whole file in memory at once. You can do that like this:
using System;
using System.IO;
class Program
{
static void Main(string[] args)
{
int line_to_edit = 2;
string sourceFile = "source.txt";
string destinationFile = "target.txt";
string tempFile = "target2.txt";
// Read the appropriate line from the file.
string lineToWrite = null;
using (StreamReader reader = new StreamReader(sourceFile))
{
for (int i = 1; i <= line_to_edit; ++i)
lineToWrite = reader.ReadLine();
}
if (lineToWrite == null)
throw new InvalidDataException("Line does not exist in " + sourceFile);
// Read from the target file and write to a new file.
int line_number = 1;
string line = null;
using (StreamReader reader = new StreamReader(destinationFile))
using (StreamWriter writer = new StreamWriter(tempFile))
{
while ((line = reader.ReadLine()) != null)
{
if (line_number == line_to_edit)
{
writer.WriteLine(lineToWrite);
}
else
{
writer.WriteLine(line);
}
line_number++;
}
}
// TODO: Delete the old file and replace it with the new file here.
}
}
You can afterwards move the file once you are sure that the write operation has succeeded (no excecption was thrown and the writer is closed).
Note that in both cases it is a bit confusing that you are using 1-based indexing for your line numbers. It might make more sense in your code to use 0-based indexing. You can have 1-based index in your user interface to your program if you wish, but convert it to a 0-indexed before sending it further.
Also, a disadvantage of directly overwriting the old file with the new file is that if it fails halfway through then you might permanently lose whatever data wasn't written. By writing to a third file first you only delete the original data after you are sure that you have another (corrected) copy of it, so you can recover the data if the computer crashes halfway through.
A final remark: I noticed that your files had an xml extension. You might want to consider if it makes more sense for you to use an XML parser to modify the contents of the files instead of replacing specific lines.
If you want to keep columns on A4 print (which is around 540px) this is a good idea
@media print {
.make-grid(print-A4);
}
.make-print-A4-column(@columns) {
@media print {
float: left;
width: percentage((@columns / @grid-columns));
}
}
You can use it like this:
<div class="col-sm-4 col-print-A4-4">
Let's face it. PHP is ugly as hell without short tags.
You can enable them in a .htaccess
file if you can't get to the php.ini
:
php_flag short_open_tag on
For mysqli users, the code will look like this:
$mysqli = new mysqli($db_host, $db_user, $db_pass, $db_name);
$result = $mysqli->query("SELECT COUNT(*) AS Students_count FROM Students")->fetch_array();
var_dump($result['Students_count']);
or:
$mysqli = new mysqli($db_host, $db_user, $db_pass, $db_name);
$result = $mysqli->query("SELECT COUNT(*) FROM Students")->fetch_array();
var_dump($result[0]);
try to disable the rewrite module in ubuntu using sudo a2dismod rewrite
. This will perhaps stop your apache server to crash.
