If your project is .net Core 3.1 API project.
update your Startup.cs in your .net core project to:
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
readonly string MyAllowSpecificOrigins = "_myAllowSpecificOrigins";
// This method gets called by the runtime. Use this method to add services to the container.

});
});
services.AddDbContext<CIVDataContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("CIVDatabaseConnection")));
services.AddControllers();

Take a look at this post, it seems like for later versions of Python, certificates are not pre installed which seems to cause this error. You should be able to run the following command to install the certifi package: /Applications/Python\ 3.6/Install\ Certificates.command
pickle
module is part of the standard library in Python for a very long time now so there is no need to install it via pip
. I wonder if you IDE or command line is not messed up somehow so that it does not find python installation path. Please check if your %PATH%
contains a path to python (e.g. C:\Python36\
or something similar) or if your IDE correctly detects root path where Python is installed.
You may already have this working, but the I created a test project with the classes below allowing you to retrieve the data into an entity, projection or dto.
Projection - this will return the code column twice, once named code and also named text (for example only). As you say above, you don't need the @Projection annotation
import org.springframework.beans.factory.annotation.Value;
public interface DeadlineTypeProjection {
String getId();
// can get code and or change name of getter below
String getCode();
// Points to the code attribute of entity class
@Value(value = "#{target.code}")
String getText();
}
DTO class - not sure why this was inheriting from your base class and then redefining the attributes. JsonProperty just an example of how you'd change the name of the field passed back to a REST end point
import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.AllArgsConstructor;
import lombok.Data;
@Data
@AllArgsConstructor
public class DeadlineType {
String id;
// Use this annotation if you need to change the name of the property that is passed back from controller
// Needs to be called code to be used in Repository
@JsonProperty(value = "text")
String code;
}
Entity class
import lombok.Data;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Data
@Entity
@Table(name = "deadline_type")
public class ABDeadlineType {
@Id
private String id;
private String code;
}
Repository - your repository extends JpaRepository<ABDeadlineType, Long> but the Id is a String, so updated below to JpaRepository<ABDeadlineType, String>
import com.example.demo.entity.ABDeadlineType;
import com.example.demo.projection.DeadlineTypeProjection;
import com.example.demo.transfer.DeadlineType;
import org.springframework.data.jpa.repository.JpaRepository;
import java.util.List;
public interface ABDeadlineTypeRepository extends JpaRepository<ABDeadlineType, String> {
List<ABDeadlineType> findAll();
List<DeadlineType> findAllDtoBy();
List<DeadlineTypeProjection> findAllProjectionBy();
}
Example Controller - accesses the repository directly to simplify code
@RequestMapping(value = "deadlinetype")
@RestController
public class DeadlineTypeController {
private final ABDeadlineTypeRepository abDeadlineTypeRepository;
@Autowired
public DeadlineTypeController(ABDeadlineTypeRepository abDeadlineTypeRepository) {
this.abDeadlineTypeRepository = abDeadlineTypeRepository;
}
@GetMapping(value = "/list")
public ResponseEntity<List<ABDeadlineType>> list() {
List<ABDeadlineType> types = abDeadlineTypeRepository.findAll();
return ResponseEntity.ok(types);
}
@GetMapping(value = "/listdto")
public ResponseEntity<List<DeadlineType>> listDto() {
List<DeadlineType> types = abDeadlineTypeRepository.findAllDtoBy();
return ResponseEntity.ok(types);
}
@GetMapping(value = "/listprojection")
public ResponseEntity<List<DeadlineTypeProjection>> listProjection() {
List<DeadlineTypeProjection> types = abDeadlineTypeRepository.findAllProjectionBy();
return ResponseEntity.ok(types);
}
}
Hope that helps

Solved it. So by default, all packages that falls under @SpringBootApplication
declaration will be scanned.
Assuming my main class ExampleApplication
that has @SpringBootApplication
declaration is declared inside com.example.something
, then all components that falls under com.example.something
is scanned while com.example.applicant
will not be scanned.
So, there are two ways to do it based on this question. Use
@SpringBootApplication(scanBasePackages={
"com.example.something", "com.example.application"})
That way, the application will scan all the specified components, but I think what if the scale were getting bigger ?
So I use the second approach, by restructuring my packages and it worked ! Now my packages structure became like this.
src/
+-- main/
¦ +-- java/
| +-- com.example/
| | +-- Application.java
| +-- com.example.model/
| | +-- User.java
| +-- com.example.controller/
| | +-- IndexController.java
| | +-- UsersController.java
| +-- com.example.service/
| +-- UserService.java
+-- resources/
+-- application.properties
Since TopicService
is a Service
class, you should annotate it with @Service
, so that Spring autowires this bean for you. Like so:
@Service
public class TopicServiceImplementation implements TopicService {
...
}
This will solve your problem.
reminder that spring doesn't scan the world , it uses targeted scanning wich means everything under the package where springbootapplication is stored. therefore this error "Consider defining a bean of type 'package' in your configuration [Spring-Boot]" may appear because you have services interfaces in a different springbootapplication package .
You could embed the ''
default in your regex by adding |$
:
>>> re.findall('\d+|$', 'aa33bbb44')[0]
'33'
>>> re.findall('\d+|$', 'aazzzbbb')[0]
''
>>> re.findall('\d+|$', '')[0]
''
Also works with re.search
pointed out by others:
>>> re.search('\d+|$', 'aa33bbb44').group()
'33'
>>> re.search('\d+|$', 'aazzzbbb').group()
''
>>> re.search('\d+|$', '').group()
''
If you are using MySQL, you can use order by FIELD(id, ...)
approach:
Company.findAll({
where: {id : {$in : companyIds}},
order: sequelize.literal("FIELD(company.id,"+companyIds.join(',')+")")
})
Keep in mind, it might be slow. But should be faster, than manual sorting with JS.
You are using Python 2 methodology instead of Python 3.
Change:
outfile=open('./immates.csv','wb')
To:
outfile=open('./immates.csv','w')
and you will get a file with the following output:
SNo,States,Dist,Population
1,Andhra Pradesh,13,49378776
2,Arunachal Pradesh,16,1382611
3,Assam,27,31169272
4,Bihar,38,103804637
5,Chhattisgarh,19,25540196
6,Goa,2,1457723
7,Gujarat,26,60383628
.....
In Python 3 csv takes the input in text mode, whereas in Python 2 it took it in binary mode.
Edited to Add
Here is the code I ran:
url='http://www.mapsofindia.com/districts-india/'
html = urllib.request.urlopen(url).read()
soup = BeautifulSoup(html)
table=soup.find('table', attrs={'class':'tableizer-table'})
list_of_rows=[]
for row in table.findAll('tr')[1:]:
list_of_cells=[]
for cell in row.findAll('td'):
list_of_cells.append(cell.text)
list_of_rows.append(list_of_cells)
outfile = open('./immates.csv','w')
writer=csv.writer(outfile)
writer.writerow(['SNo', 'States', 'Dist', 'Population'])
writer.writerows(list_of_rows)
Type android on your command line and install "Android SDK Build-tools"
Try setting the system default encoding as utf-8
at the start of the script, so that all strings are encoded using that.
Example -
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
The above should set the default encoding as utf-8
.
You want to convert html (a byte-like object) into a string using .decode
, e.g. html = response.read().decode('utf-8')
.
First of all, @Fetch(FetchMode.JOIN)
and @ManyToOne(fetch = FetchType.LAZY)
are antagonistic because @Fetch(FetchMode.JOIN)
is equivalent to the JPA FetchType.EAGER
.
Eager fetching is rarely a good choice, and for predictable behavior, you are better off using the query-time JOIN FETCH
directive:
public interface PlaceRepository extends JpaRepository<Place, Long>, PlaceRepositoryCustom {
@Query(value = "SELECT p FROM Place p LEFT JOIN FETCH p.author LEFT JOIN FETCH p.city c LEFT JOIN FETCH c.state where p.id = :id")
Place findById(@Param("id") int id);
}
public interface CityRepository extends JpaRepository<City, Long>, CityRepositoryCustom {
@Query(value = "SELECT c FROM City c LEFT JOIN FETCH c.state where c.id = :id")
City findById(@Param("id") int id);
}
In the spring boot reference,it said:
When a class doesn’t include a package declaration it is considered to be in the “default package”. The use of the “default package” is generally discouraged, and should be avoided. It can cause particular problems for Spring Boot applications that use @ComponentScan, @EntityScan or @SpringBootApplication annotations, since every class from every jar, will be read.

+- myproject
+- Application.java
|
+- domain
| +- Customer.java

In your cases. You must add scanBasePackages
in the @SpringBootApplication
annotation.just like@SpringBootApplication(scanBasePackages={"domain","contorller"..})
#Use this, THIS IS FOR EXTRACTING NUMBER FROM STRING IN GENERAL. #To get all the numeric occurences.

Please have a look at the Spring Data JPA - Reference Documentation, section 5.3. Query Methods, especially at section 5.3.2. Query Creation, in "Table 3. Supported keywords inside method names" (links as of 2019-05-03).
I think it has exactly what you need and same query as you stated should work...

In many cases, continuing to scrape data from a website even when the server is requesting you not to is unethical. However, in the cases where it isn't, you can utilize a list of public proxies in order to scrape a website with many different IP addresses.
For those coming across this question more recently, .values
is deprecated as of Sequelize 3.0.0. Use .get()
instead to get the plain javascript object. So the above code would change to:
var nodedata = node.get({ plain: true });
Sequelize docs here
What does res.render do and what does the html file look like?
res.render()
function compiles your template (please don't use ejs), inserts locals there, and creates html output out of those two things.
Answering Edit 2 part.
// here you set that all templates are located in `/views` directory
app.set('views', __dirname + '/views');
// here you set that you're using `ejs` template engine, and the
// default extension is `ejs`
app.set('view engine', 'ejs');
// here you render `orders` template
response.render("orders", {orders: orders_json});
So, the template path is views/
(first part) + orders
(second part) + .ejs
(third part) === views/orders.ejs
Anyway, express.js documentation is good for what it does. It is API reference, not a "how to use node.js" book.
In Sequelize version 5 you might also can use this way (full use Operator Sequelize) :
var condition =
{
[Op.or]: [
{
LastName: {
[Op.eq]: "Doe"
},
},
{
FirstName: {
[Op.or]: ["John", "Jane"]
}
},
{
Age:{
[Op.gt]: 18
}
}
]
}
And then, you must include this :
const Op = require('Sequelize').Op
and pass it in :
Student.findAll(condition)
.success(function(students){
//
})
It could beautifully generate SQL like this :
"SELECT * FROM Student WHERE LastName='Doe' OR FirstName in ("John","Jane") OR Age>18"
@Query("SELECT rd FROM ReleaseDateType rd, CacheMedia cm WHERE ...")
Fixed, While using CrudRepository
of Spring , we have to append the propertyname correctly after findBy otherwise it will give you exception
"No Property Found for Type”
I was getting this exception as. because property name and method name were not in sync.
I have used below code for DB Access.
public interface UserDao extends CrudRepository<User, Long> {
User findByUsername(String username);
and my Domain User has property.
@Entity
public class User implements UserDetails {
/**
*
*/
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "userId", nullable = false, updatable = false)
private Long userId;
private String username;
Warning: This might inflate executable file size a little bit and cost a little runtime performance. IMO, this would be better if golang has such feature like macro or function decorator.
If you want to mock functions without changing its API, the easiest way is to change the implementation a little bit:
func getPage(url string) string {
if GetPageMock != nil {
return GetPageMock()
}
// getPage real implementation goes here!
}
func downloader() {
if GetPageMock != nil {
return GetPageMock()
}
// getPage real implementation goes here!
}
var GetPageMock func(url string) string = nil
var DownloaderMock func() = nil
This way we can actually mock one function out of the others. For more convenient we can provide such mocking boilerplate:
// download.go
func getPage(url string) string {
if m.GetPageMock != nil {
return m.GetPageMock()
}
// getPage real implementation goes here!
}
func downloader() {
if m.GetPageMock != nil {
return m.GetPageMock()
}
// getPage real implementation goes here!
}
type MockHandler struct {
GetPage func(url string) string
Downloader func()
}
var m *MockHandler = new(MockHandler)
func Mock(handler *MockHandler) {
m = handler
}
In test file:
// download_test.go
func GetPageMock(url string) string {
// ...
}
func TestDownloader(t *testing.T) {
Mock(&MockHandler{
GetPage: GetPageMock,
})
// Test implementation goes here!
Mock(new(MockHandler)) // Reset mocked functions
}
Following with Oleg answer, if you want to find ALL objects in a List filtered by a property, you could do something like:
//Search into a generic list ALL items with a generic property
public final class SearchTools {
public static <T> List<T> findByProperty(Collection<T> col, Predicate<T> filter) {
List<T> filteredList = (List<T>) col.stream().filter(filter).collect(Collectors.toList());
return filteredList;
}
//Search in the list "listItems" ALL items of type "Item" with the specific property "iD_item=itemID"
public static final class ItemTools {
public static List<Item> findByItemID(Collection<Item> listItems, String itemID) {
return SearchTools.findByProperty(listItems, item -> itemID.equals(item.getiD_Item()));
}
}
}
and similarly if you want to filter ALL items in a HashMap with a certain Property
//Search into a MAP ALL items with a given property
public final class SearchTools {
public static <T> HashMap<String,T> filterByProperty(HashMap<String,T> completeMap, Predicate<? super Map.Entry<String,T>> filter) {
HashMap<String,T> filteredList = (HashMap<String,T>) completeMap.entrySet().stream()
.filter(filter)
.collect(Collectors.toMap(map -> map.getKey(), map -> map.getValue()));
return filteredList;
}
//Search into the MAP ALL items with specific properties
public static final class ItemTools {
public static HashMap<String,Item> filterByParentID(HashMap<String,Item> mapItems, String parentID) {
return SearchTools.filterByProperty(mapItems, mapItem -> parentID.equals(mapItem.getValue().getiD_Parent()));
}
public static HashMap<String,Item> filterBySciName(HashMap<String,Item> mapItems, String sciName) {
return SearchTools.filterByProperty(mapItems, mapItem -> sciName.equals(mapItem.getValue().getSciName()));
}
}
Try this:
$em = $this->getDoctrine()->getManager();
$entities = $em->getRepository('MyBundle:MyTable')->findBy(array(), array('username' => 'ASC'));
soup = BeautifulSoup(html)
for hit in soup.findAll(attrs={'class' : 'MYCLASS'}):
hit = hit.text.strip()
print hit
This will print: THIS IS MY TEXT Try this..
This is probably because of mod_security
or some similar server security feature which blocks known spider/bot user agents (urllib
uses something like python urllib/3.3.0
, it's easily detected). Try setting a known browser user agent with:
from urllib.request import Request, urlopen
req = Request('http://www.cmegroup.com/trading/products/#sortField=oi&sortAsc=false&venues=3&page=1&cleared=1&group=1', headers={'User-Agent': 'Mozilla/5.0'})
webpage = urlopen(req).read()
This works for me.
By the way, in your code you are missing the ()
after .read
in the urlopen
line, but I think that it's a typo.
TIP: since this is exercise, choose a different, non restrictive site. Maybe they are blocking urllib
for some reason...
lines
is a list. re.findall()
doesn't take lists.

>>> match = re.findall('[A-Z]+', lines)

From help(file.readlines)
. I.e. readlines()
is for loops/iterating:
readlines(...)
readlines([size]) -> list of strings, each a line from the file.
To find all uppercase characters in your file:

I've been using similar code to this and have found it's always worth reading the documentation... as usual!
findall() will only find elements which are direct children of the current tag. So, not really ALL.
It might be worth your while trying to get your code working with the following, especially if you're dealing with big and complex xml files so that that sub-sub-elements (etc.) are also included. If you know yourself where elements are in your xml, then I suppose it'll be fine! Just thought this was worth remembering.
root.iter()
ref: https://docs.python.org/3/library/xml.etree.elementtree.html#finding-interesting-elements "Element.findall() finds only elements with a tag which are direct children of the current element. Element.find() finds the first child with a particular tag, and Element.text accesses the element’s text content. Element.get() accesses the element’s attributes:"
EntityFunctions
is obsolete. Consider using DbFunctions
instead.
var eventsCustom = eventCustomRepository.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference)
.Where(x => DbFunctions.TruncateTime(x.DateTimeStart) == currentDate.Date);
A ternary will suffice. change:
gotdata = dlist[1]
to
gotdata = dlist[1] if len(dlist) > 1 else 'null'
this is a shorter way of expressing
if len(dlist) > 1:
gotdata = dlist[1]
else:
gotdata = 'null'
All the above answers really help me to construct my answer, because of this I voted for all the answers that other users put it out: But I finally put together my own answer to exact problem I was dealing with:
As question clearly defined I had to access some of the siblings and its children in a dom structure: This solution will iterate over the images in the dom structure and construct image name using product title and save the image to the local directory.
import urlparse
from urllib2 import urlopen
from urllib import urlretrieve
from BeautifulSoup import BeautifulSoup as bs
import requests
def getImages(url):
#Download the images
r = requests.get(url)

output_folder = '~/amazon'
#extracting the images that in div(s)
for div in soup.findAll('div', attrs={'class':'image'}):
modified_file_name = None
try:
#getting the data div using findNext
nextDiv = div.findNext('div', attrs={'class':'data'})
#use findNext again on previous object to get to the anchor tag
fileName = nextDiv.findNext('a').text
modified_file_name = fileName.replace(' ','-') + '.jpg'
except TypeError:
print 'skip'
imageUrl = div.find('img')['src']
outputPath = os.path.join(output_folder, modified_file_name)

getImages(url)
Try this instead:
echo "This is 02G05 a test string 20-Jul-2012" | sed 's/.* \([0-9]\+G[0-9]\+\) .*/\1/'
But note, if there is two pattern on one line, it will prints the 2nd.
Maybe you can try the following without XPath
from simplified_scrapy.simplified_doc import SimplifiedDoc
html = '''
<html>
<body>
<div>
<h1>Example Domain</h1>
<p>This domain is for use in illustrative examples in documents. You may use this
domain in literature without prior coordination or asking for permission.</p>
<p><a href="https://www.iana.org/domains/example">More information...</a></p>
</div>
</body>
</html>
'''
# What XPath can do, so can it
doc = SimplifiedDoc(html)
# The result is the same as doc.getElementByTag('body').getElementByTag('div').getElementByTag('h1').text
print (doc.body.div.h1.text)
print (doc.div.h1.text)
print (doc.h1.text) # Shorter paths will be faster
print (doc.div.getChildren())
print (doc.div.getChildren('p'))
In my case, to use Pageable
and Sorting
at the same time I used like below. In this case I took all elements using pagination and sorting by id
by descending order:
modelRepository.findAll(PageRequest.of(page, 10, Sort.by("id").descending()))
Like above based on your requirements you can sort data with 2 columns as well.
Another simple way get by using findall in yii
$id =101;
$comments = EmailArchive::model()->findAll(array("condition"=>"':email_id'=$id"));
foreach($comments as $comments_1)
{
echo "email:".$comments_1['email_id'];
}
Just modify your WebAPIConfig.cs as bellow
Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { action = "get", id = RouteParameter.Optional });
Then implement your API as bellow
// GET: api/Controller_Name/Show/1
[ActionName("Show")]
[HttpGet]
public EventPlanner Id(int id){}
If you want to run .py files in Windows, Try installing Git bash Then download python(Required Version) from python.org and install in the main c drive folder
For me, its :
"C:\Python38"
then open Git Bash and go to the respective folder where your .py file is stored :
For me, its :
File Location : "Downloads" File Name : Train.py
So i changed my Current working Directory From "C:/User/(username)/" to "C:/User/(username)/Downloads"
then i will run the below command
" /c/Python38/python Train.py "
and it will run successfully.
But if it give the below error :
from sklearn.model_selection import train_test_split ModuleNotFoundError: No module named 'sklearn'
Then Do not panic :
and use this command :
" /c/Python38/Scripts/pip install sklearn "
and after it has installed sklearn go back and run the previous command :
" /c/Python38/python Train.py "
and it will run successfully.

The following line is looking for the exact NavigableString 'Python':
>>> soup.body.findAll(text='Python')
[]
Note that the following NavigableString is found:
>>> soup.body.findAll(text='Python Jobs')
[u'Python Jobs']
Note this behaviour:
>>> import re
>>> soup.body.findAll(text=re.compile('^Python$'))
[]
So your regexp is looking for an occurrence of 'Python' not the exact match to the NavigableString 'Python'.

I've searched deep into the code, step by step into the following files:
https://github.com/sdepold/sequelize/blob/master/test/Model/destroy.js
https://github.com/sdepold/sequelize/blob/master/lib/model.js#L140
https://github.com/sdepold/sequelize/blob/master/lib/query-interface.js#L207-217
https://github.com/sdepold/sequelize/blob/master/lib/connectors/mysql/query-generator.js
What I found:
There isn't a deleteAll method, there's a destroy() method you can call on a record, for example:
Project.find(123).on('success', function(project) {
project.destroy().on('success', function(u) {
if (u && u.deletedAt) {
// successfully deleted the project
}
})
})
The error also happens when trying to use the

# ...
with a Python version that is too old (like Python 2.X) and does not support using with
together with multiprocessing pools.
(See this answer https://stackoverflow.com/a/25968716/1426569 to another question for more details)
A referral was returned from the server error usually means that the IP address is not hosted by the domain that is provided on the connection string. For more detail, see this link:
Referral was returned AD Provider
To illustrate the problem, we define two IP addresses hosted on different domains:
IP Address DC Name Notes
172.1.1.10 ozkary.com Production domain
172.1.30.50 ozkaryDev.com Development domain
If we defined a LDAP connection string with this format:
LDAP://172.1.1.10:389/OU=USERS,DC=OZKARYDEV,DC=COM
This will generate the error because the IP is actually on the OZKARY DC not the OZKARYDEV DC. To correct the problem, we would need to use the IP address that is associated to the domain.
For the less specific case (not just the code in the question - since this is one of the first results in Google for this generic error message. This error also occurs when running certain os command with None argument.
For example:
os.path.exists(arg)
os.stat(arg)
Will raise this exception when arg is None.

Your second delegate is not a rewrite of the first in anonymous delegate (rather than lambda) format. Look at your conditions.
First:
x.ID == packageId || x.Parent.ID == packageId || x.Parent.Parent.ID == packageId
Second:
(x.ID == packageId) || (x.Parent != null && x.Parent.ID == packageId) ||
(x.Parent != null && x.Parent.Parent != null && x.Parent.Parent.ID == packageId)
The call to the lambda would throw an exception for any x
where the ID doesn't match and either the parent is null or doesn't match and the grandparent is null. Copy the null checks into the lambda and it should work correctly.
If your original object is not a List<T>
, then we have no way of knowing what the return type of FindAll()
is, and whether or not this implements the IQueryable
interface. If it does, then that likely explains the discrepancy. Because lambdas can be converted at compile time into an Expression<Func<T>>
but anonymous delegates cannot, then you may be using the implementation of IQueryable
when using the lambda version but LINQ-to-Objects when using the anonymous delegate version.
This would also explain why your lambda is not causing a NullReferenceException
. If you were to pass that lambda expression to something that implements IEnumerable<T>
but not IQueryable<T>
, runtime evaluation of the lambda (which is no different from other methods, anonymous or not) would throw a NullReferenceException
the first time it encountered an object where ID
was not equal to the target and the parent or grandparent was null.
Consider the following simple example:
IQueryable<MyObject> source = ...; // some object that implements IQueryable<MyObject>
var anonymousMethod = source.Where(delegate(MyObject o) { return o.Name == "Adam"; });
var expressionLambda = source.Where(o => o.Name == "Adam");
These two methods produce entirely different results.
The first query is the simple version. The anonymous method results in a delegate that's then passed to the IEnumerable<MyObject>.Where
extension method, where the entire contents of source
will be checked (manually in memory using ordinary compiled code) against your delegate. In other words, if you're familiar with iterator blocks in C#, it's something like doing this:
public IEnumerable<MyObject> MyWhere(IEnumerable<MyObject> dataSource, Func<MyObject, bool> predicate)
{
foreach(MyObject item in dataSource)
{
if(predicate(item)) yield return item;
}
}
The salient point here is that you're actually performing your filtering in memory on the client side. For example, if your source were some SQL ORM, there would be no WHERE
clause in the query; the entire result set would be brought back to the client and filtered there.
The second query, which uses a lambda expression, is converted to an Expression<Func<MyObject, bool>>
and uses the IQueryable<MyObject>.Where()
extension method. This results in an object that is also typed as IQueryable<MyObject>
. All of this works by then passing the expression to the underlying provider. This is why you aren't getting a NullReferenceException
. It's entirely up to the query provider how to translate the expression (which, rather than being an actual compiled function that it can just call, is a representation of the logic of the expression using objects) into something it can use.
An easy way to see the distinction (or, at least, that there is) a distinction, would be to put a call to AsEnumerable()
before your call to Where
in the lambda version. This will force your code to use LINQ-to-Objects (meaning it operates on IEnumerable<T>
like the anonymous delegate version, not IQueryable<T>
like the lambda version currently does), and you'll get the exceptions as expected.
The long and the short of it is that your lambda expression is being translated into some kind of query against your data source, whereas the anonymous method version is evaluating the entire data source in memory. Whatever is doing the translating of your lambda into a query is not representing the logic that you're expecting, which is why it isn't producing the results you're expecting.
Try to check if the div has a class attribute first, like this:
soup = BeautifulSoup(sdata)
mydivs = soup.findAll('div')
for div in mydivs:
if "class" in div:
if (div["class"]=="stylelistrow"):
print div
I resolved this by adding @Transactional
to the base/generic Hibernate DAO implementation class (the parent class which implements the saveOrUpdate() method inherited by the DAO I use in the main program), i.e. the @Transactional
needs to be specified on the actual class which implements the method. My assumption was instead that if I declared @Transactional
on the child class then it included all of the methods that were inherited by the child class. However it seems that the @Transactional
annotation only applies to methods implemented within a class and not to methods inherited by a class.
eval(a_string)
evaluates a string as Python code. Obviously this is not particularly safe. You can get safer (more restricted) evaluation by using the literal_eval
function from the ast
module.
raw_input()
is called that in Python 2.x because it gets raw, not "interpreted" input. input()
interprets the input, i.e. is equivalent to eval(raw_input())
.
In Python 3.x, input()
does what raw_input()
used to do, and you must evaluate the contents manually if that's what you want (i.e. eval(input())
).
Just query the "memberOf" property and iterate though the return, example:
search.PropertiesToLoad.Add("memberOf");
StringBuilder groupNames = new StringBuilder(); //stuff them in | delimited
SearchResult result = search.FindOne();
int propertyCount = result.Properties["memberOf"].Count;
String dn;
int equalsIndex, commaIndex;
for (int propertyCounter = 0; propertyCounter < propertyCount;
propertyCounter++)
{
dn = (String)result.Properties["memberOf"][propertyCounter];
equalsIndex = dn.IndexOf("=", 1);
commaIndex = dn.IndexOf(",", 1);
if (-1 == equalsIndex)
{
return null;
}
groupNames.Append(dn.Substring((equalsIndex + 1),
(commaIndex - equalsIndex) - 1));
groupNames.Append("|");
}
return groupNames.ToString();
This just stuffs the group names into the groupNames string, pipe delimited, but when you spin through you can do whatever you want with them
Based on Adam Sills answer above - here's a nice clean extensions method for Contains... :)
///----------------------------------------------------------------------
/// <summary>
/// Determines whether the specified list contains the matching string value
/// </summary>
/// <param name="list">The list.</param>
/// <param name="value">The value to match.</param>
/// <param name="ignoreCase">if set to <c>true</c> the case is ignored.</param>
/// <returns>
/// <c>true</c> if the specified list contais the matching string; otherwise, <c>false</c>.
/// </returns>
///----------------------------------------------------------------------
public static bool Contains(this List<string> list, string value, bool ignoreCase = false)
{
return ignoreCase ?
list.Any(s => s.Equals(value, StringComparison.OrdinalIgnoreCase)) :
list.Contains(value);
}
Another handy aspect of @Valid not mentioned above is that (ie: using Postman to test an endpoint) @Valid will format the output of an incorrect REST call into formatted JSON instead of a blob of barely readable text. This is very useful if you are creating a commercially consumable API for your users.
One liner using String.protype.matchAll
(ES2020):
[...sourceStr.matchAll(new RegExp(searchStr, 'gi'))].map(a => a.index)
Using your values:
const sourceStr = 'I learned to play the Ukulele in Lebanon.';
const searchStr = 'le';
const indexes = [...sourceStr.matchAll(new RegExp(searchStr, 'gi'))].map(a => a.index);
console.log(indexes); // [2, 25, 27, 33]
If you're worried about doing a spread and a map()
in one line, I ran it with a for...of
loop for a million iterations (using your strings). The one liner averages 1420ms while the for...of
averages 1150ms on my machine. That's not an insignificant difference, but the one liner will work fine if you're only doing a handful of matches.
For me:
<input id="color" value="Blue"/>
This can be fetched by below snippet.
page = requests.get("https://www.abcd.com")
soup = BeautifulSoup(page.content, 'html.parser')
colorName = soup.find(id='color')
print(color['value'])
I completely respect using Beautiful Soup to get rendered content, but it may not be the ideal package for acquiring the rendered content on a page.
I had a similar problem to get rendered content, or the visible content in a typical browser. In particular I had many perhaps atypical cases to work with such a simple example below. In this case the non displayable tag is nested in a style tag, and is not visible in many browsers that I have checked. Other variations exist such as defining a class tag setting display to none. Then using this class for the div.
<html>
<title> Title here</title>
<body>
lots of text here <p> <br>
<h1> even headings </h1>
<style type="text/css">
<div > this will not be visible </div>
</style>
</body>
</html>
One solution posted above is:
html = Utilities.ReadFile('simple.html')
soup = BeautifulSoup.BeautifulSoup(html)
texts = soup.findAll(text=True)
visible_texts = filter(visible, texts)
print(visible_texts)
[u'\n', u'\n', u'\n\n lots of text here ', u' ', u'\n', u' even headings ', u'\n', u' this will not be visible ', u'\n', u'\n']
This solution certainly has applications in many cases and does the job quite well generally but in the html posted above it retains the text that is not rendered. After searching SO a couple solutions came up here BeautifulSoup get_text does not strip all tags and JavaScript and here Rendered HTML to plain text using Python
I tried both these solutions: html2text and nltk.clean_html and was surprised by the timing results so thought they warranted an answer for posterity. Of course, the speeds highly depend on the contents of the data...
One answer here from @Helge was about using nltk of all things.
import nltk
%timeit nltk.clean_html(html)
was returning 153 us per loop
It worked really well to return a string with rendered html. This nltk module was faster than even html2text, though perhaps html2text is more robust.
betterHTML = html.decode(errors='ignore')
%timeit html2text.html2text(betterHTML)
%3.09 ms per loop
Just FYI, I had the same error and was using the correct credentials but my LDAP url was wrong :(
I got the exact same error message and code
The reason why your code is slow is that your LDAP query retrieves every single user object in your domain even though you're only interested in one user with a common name of "Adit":
dSearcher.Filter = "(&(objectClass=user))";
So to optimize, you need to narrow your LDAP query to just the user you are interested in. Try something like:
dSearcher.Filter = "(&(objectClass=user)(cn=Adit))";
In addition, don't forget to dispose these objects when done:
dEntry
dSearcher
Here is a practical addition to the answers of PierreBdR and Moe:
dir()
seems to be enough.For old-style classes, we can at least do what a standard module does to support tab completion: in addition to dir()
, look for __class__
, and then to go for its __bases__
:
# code borrowed from the rlcompleter module
# tested under Python 2.6 ( sys.version = '2.6.5 (r265:79063, Apr 16 2010, 13:09:56) \n[GCC 4.4.3]' )
# or: from rlcompleter import get_class_members
def get_class_members(klass):
ret = dir(klass)
if hasattr(klass,'__bases__'):
for base in klass.__bases__:
ret = ret + get_class_members(base)
return ret
def uniq( seq ):
""" the 'set()' way ( use dict when there's no set ) """
return list(set(seq))
def get_object_attrs( obj ):
# code borrowed from the rlcompleter module ( see the code for Completer::attr_matches() )
ret = dir( obj )
## if "__builtins__" in ret:
## ret.remove("__builtins__")
if hasattr( obj, '__class__'):
ret.append('__class__')
ret.extend( get_class_members(obj.__class__) )
ret = uniq( ret )
return ret
(Test code and output are deleted for brevity, but basically for new-style objects we seem to have the same results for get_object_attrs()
as for dir()
, and for old-style classes the main addition to the dir()
output seem to be the __class__
attribute.)
I don't think there are hard and fast rules for this type of thing, but I usually go by the guideline of using the lightest possible way until absolutely necessary.
For example, let's say you have a Person
class and a Group
class. A Group
instance has many people, so a List here would make sense. When I declare the list object in Group
I will use an IList<Person>
and instantiate it as a List
.
public class Group {
private IList<Person> people;
public Group() {
this.people = new List<Person>();
}
}
And, if you don't even need everything in IList
you can always use IEnumerable
too. With modern compilers and processors, I don't think there is really any speed difference, so this is more just a matter of style.
I do agree that perceived performance is really all that matters. But sometimes I just want to find out which method of doing something is faster. Sometimes the difference is HUGE and worth knowing.
You could just use javascript timers. But I typically get much more consistent results using the native Chrome (now also in Firefox and Safari) devTool methods console.time()
& console.timeEnd()
var iterations = 1000000;
console.time('Function #1');
for(var i = 0; i < iterations; i++ ){
functionOne();
};
console.timeEnd('Function #1')
console.time('Function #2');
for(var i = 0; i < iterations; i++ ){
functionTwo();
};
console.timeEnd('Function #2')
Chrome canary recently added Line Level Profiling the dev tools sources tab which let's you see exactly how long each line took to execute!
This is not possible. You will need to do this one by one. You could:
Try with this:
var fn_name = "Colours",
fn = eval("populate_"+fn_name);
fn(args1,argsN);
You need to add RouterModule
to imports
of every @NgModule()
where components use any component or directive from (in this case routerLink
and <router-outlet>
.
declarations: []
is to make components, directives, pipes, known inside the current module.
exports: []
is to make components, directives, pipes, available to importing modules. What is added to declarations
only is private to the module. exports
makes them public.

If your terminal supports it, you can use ANSI escape codes to use color in your output. It generally works for Unix shell prompts; however, it doesn't work for Windows Command Prompt (Although, it does work for Cygwin). For example, you could define constants like these for the colors:
public static final String ANSI_RESET = "\u001B[0m";
public static final String ANSI_BLACK = "\u001B[30m";
public static final String ANSI_RED = "\u001B[31m";
public static final String ANSI_GREEN = "\u001B[32m";
public static final String ANSI_YELLOW = "\u001B[33m";
public static final String ANSI_BLUE = "\u001B[34m";
public static final String ANSI_PURPLE = "\u001B[35m";
public static final String ANSI_CYAN = "\u001B[36m";
public static final String ANSI_WHITE = "\u001B[37m";
Then, you could reference those as necessary.
For example, using the above constants, you could make the following red text output on supported terminals:
System.out.println(ANSI_RED + "This text is red!" + ANSI_RESET);
Update: You might want to check out the Jansi library. It provides an API and has support for Windows using JNI. I haven't tried it yet; however, it looks promising.
Update 2: Also, if you wish to change the background color of the text to a different color, you could try the following as well:
public static final String ANSI_BLACK_BACKGROUND = "\u001B[40m";
public static final String ANSI_RED_BACKGROUND = "\u001B[41m";
public static final String ANSI_GREEN_BACKGROUND = "\u001B[42m";
public static final String ANSI_YELLOW_BACKGROUND = "\u001B[43m";
public static final String ANSI_BLUE_BACKGROUND = "\u001B[44m";
public static final String ANSI_PURPLE_BACKGROUND = "\u001B[45m";
public static final String ANSI_CYAN_BACKGROUND = "\u001B[46m";
public static final String ANSI_WHITE_BACKGROUND = "\u001B[47m";
For instance:
System.out.println(ANSI_GREEN_BACKGROUND + "This text has a green background but default text!" + ANSI_RESET);
System.out.println(ANSI_RED + "This text has red text but a default background!" + ANSI_RESET);
System.out.println(ANSI_GREEN_BACKGROUND + ANSI_RED + "This text has a green background and red text!" + ANSI_RESET);

Here testcases1 table contains all datas and executions1 table contains some data among testcases1 table. I am retrieving only the datas which are not present in exections1 table. ( and even I am giving some conditions inside that you can also give.) specify condition which should not be there in retrieving data should be inside brackets.
Suppose that the column PractitionerId is a unique, then you can use the following loop
DECLARE @PractitionerId int = 0
WHILE(1 = 1)
BEGIN
SELECT @PractitionerId = MIN(PractitionerId)
FROM dbo.Practitioner WHERE PractitionerId > @PractitionerId
IF @PractitionerId IS NULL BREAK
SELECT @PractitionerId
END
I recently used this to read all the lines from a file:
alist = open('maze.txt').read().split()
or you can use this for that little bit of extra added safety:
with f as open('maze.txt'):
alist = f.read().split()
It doesn't work with whitespace in-between text in a single line, but it looks like your example file might not have whitespace splitting the values. It is a simple solution and it returns an accurate list of values, and does not add an empty string: ''
for every empty line, such as a newline at the end of the file.
To remove a timezone (tzinfo) from a datetime object:
# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)
If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.
# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)
Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime
object to insert into the database. The solution is to convert your datetime.datetime
object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime
objects where one is timezone aware and another is timezone naive.
##############################################################################
# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
arrowDt = arrowObj.to("utc").datetime
# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)
# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()
# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3
# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True

I know this is an old question but I just want to comment here: To any extent email addresses ARE case sensitive, most users would be "very unwise" to actively use an email address that requires capitals. They would soon stop using the address because they'd be missing a lot of their mail. (Unless they have a specific reason to make things difficult, and they expect mail only from specific senders they know.)
That's because imperfect humans as well as imperfect software exist, (Surprise!) which will assume all email is lowercase, and for this reason these humans and software will send messages using a "lower cased version" of the address regardless of how it was provided to them. If the recipient is unable to receive such messages, it won't be long before they notice they're missing a lot, and switch to a lowercase-only email address, or get their server set up to be case-insensitive.
I found all these a little clumsy and I'm not too expert on regular expressions, so here's a simpler version. It would be quite easy to translate it to your favourite server-side language, assuming that the string already in Unicode:
// String containing replacement characters for stripping accents
var stripstring =
'AAAAAAACEEEEIIII'+
'DNOOOOO.OUUUUY..'+
'aaaaaaaceeeeiiii'+
'dnooooo.ouuuuy.y'+
'AaAaAaCcCcCcCcDd'+
'DdEeEeEeEeEeGgGg'+
'GgGgHhHhIiIiIiIi'+
'IiIiJjKkkLlLlLlL'+
'lJlNnNnNnnNnOoOo'+
'OoOoRrRrRrSsSsSs'+
'SsTtTtTtUuUuUuUu'+
'UuUuWwYyYZzZzZz.';
function stripaccents(str){
var answer='';
for(var i=0;i<str.length;i++){
var ch=str[i];
var chindex=ch.charCodeAt(0)-192; // Index of character code in the strip string
if(chindex>=0 && chindex<stripstring.length){
// Character is within our table, so we can strip the accent...
var outch=stripstring.charAt(chindex);
// ...unless it was shown as a '.'
if(outch!='.')ch=outch;
}
answer+=ch;
}
return answer;
}
Suppose your "Don't Check" list is on Sheet2 in cells A1:A100

What you would do is:
Conditional Formatting

=ISNUMBER(MATCH($A1,Sheet2!$A$1:$A$100,0))
and select how you want those rows formattedAnd that should do the trick.

To your .cs file. If it not available add it through the Project References as it is not included by default in a new project.
This is my solution to this problem. First I made the ConnectionProperties Class that saves the items I need to change in the original connection string. The _name variable in the ConnectionProperties class is important to be the name of the connectionString The first method takes a connection string and changes the option you want with the new value.
private String changeConnStringItem(string connString,string option, string value)
{
String[] conItems = connString.Split(';');
String result = "";
foreach (String item in conItems)
{
if (item.StartsWith(option))
{
result += option + "=" + value + ";";
}
else
{
result += item + ";";
}
}
return result;
}
You can change this method to accomodate your own needs. I have both mysql and mssql connections so I needed both of them. Of course you can refine this draft code for yourself.
private void changeConnectionSettings(ConnectionProperties cp)
{
var cnSection = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
String connString = cnSection.ConnectionStrings.ConnectionStrings[cp.Name].ConnectionString;
connString = changeConnStringItem(connString, "provider connection string=\"data source", cp.DataSource);
connString = changeConnStringItem(connString, "provider connection string=\"server", cp.DataSource);
connString = changeConnStringItem(connString, "user id", cp.Username);
connString = changeConnStringItem(connString, "password", cp.Password);
connString = changeConnStringItem(connString, "initial catalog", cp.InitCatalogue);
connString = changeConnStringItem(connString, "database", cp.InitCatalogue);
cnSection.ConnectionStrings.ConnectionStrings[cp.Name].ConnectionString = connString;
cnSection.Save();
ConfigurationManager.RefreshSection("connectionStrings");
}
As I didn't want to add trivial information I ommited the Properties region of my code. Please add it if you want this to work.
class ConnectionProperties
{
private String _name;
private String _dataSource;
private String _username;
private String _password;

In terms of performance, the timing reflects the opcode

10000000 loops, best of 3: 0.11 usec per loop
$ python -mtimeit -s'd = dict((i, i) for i in range(10000))' "d.has_key('foo')"
1000000 loops, best of 3: 0.205 usec per loop

Had the same problem. found some videos on Youtube. So here is an even simpler suggestion. This is all the code you need:
#include <QDebug>
int main(int argc, char *argv[])
{
qDebug() <<"Hello World"<< endl;
return 0;
}
The above code comes from Qt5 Tutorial: Building a simple Console application by
Dominique Thiebaut
State machines are not something that inherently needs a tutorial to be explained or even used. What I suggest is that you take a look at the data and how it needs to be parsed.
For example, I had to parse the data protocol for a Near Space balloon flight computer, it stored data on the SD card in a specific format (binary) which needed to be parsed out into a comma seperated file. Using a state machine for this makes the most sense because depending on what the next bit of information is we need to change what we are parsing.
The code is written using C++, and is available as ParseFCU. As you can see, it first detects what version we are parsing, and from there it enters two different state machines.
It enters the state machine in a known-good state, at that point we start parsing and depending on what characters we encounter we either move on to the next state, or go back to a previous state. This basically allows the code to self-adapt to the way the data is stored and whether or not certain data exists at all even.
In my example, the GPS string is not a requirement for the flight computer to log, so processing of the GPS string may be skipped over if the ending bytes for that single log write is found.
State machines are simple to write, and in general I follow the rule that it should flow. Input going through the system should flow with certain ease from state to state.
You can also add a hover style to the dropdown.

Use the CORS package available on Nuget: Install-Package Microsoft.AspNet.WebApi.Cors
In your WebApiConfig.cs

Add an attribute to the controllers you need to handle cors:
[EnableCors(origins: "<origin address in here>", headers: "*", methods: "*")]

typing.Union
Union type; Union[X, Y] means either X or Y.
Hence the proper way to represent more than one return data type is
from typing import Union
def foo(client_id: str) -> Union[list,bool]
But do note that typing is not enforced. Python continues to remain a dynamically-typed language. The annotation syntax has been developed to help during the development of the code prior to being released into production. As PEP 484 states, "no type checking happens at runtime."
>>> def foo(a:str) -> list:
... return("Works")
...
>>> foo(1)
'Works'
As you can see I am passing a int value and returning a str. However the __annotations__
will be set to the respective values.
>>> foo.__annotations__
{'return': <class 'list'>, 'a': <class 'str'>}
Please Go through PEP 483 for more about Type hints. Also see What are Type hints in Python 3.5?
Kindly note that this is available only for Python 3.5 and upwards. This is mentioned clearly in PEP 484.

In an SQL query, if the inner query executes for every row of the outer query. If the inner query is executed for once and the result is consumed by the outer query, then it is called as non co-related query.
There a small difference when u use rgba(255,255,255,a),background color becomes more and more lighter as the value of 'a' increase from 0.0 to 1.0. Where as when use rgba(0,0,0,a), the background color becomes more and more darker as the value of 'a' increases from 0.0 to 1.0. Having said that, its clear that both (255,255,255,0) and (0,0,0,0) make background transparent. (255,255,255,1) would make the background completely white where as (0,0,0,1) would make background completely black.

Any user whose login shell setting in /etc/passwd
is an interactive shell can login. I don't think there's a totally reliable way to tell if a program is an interactive shell; checking whether it's in /etc/shells
is probably as good as you can get.
Other users can also login, but the program they run should not allow them to get much access to the system. And users that aren't allowed to login at all should have /etc/false
as their shell -- this will just log them out immediately.
For me, it was having display: none;
#spinner-success-text {
display: none;
transition: all 1s ease-in;
}
#spinner-success-text.show {
display: block;
}
Removing it, and using opacity
instead, fixed the issue.
#spinner-success-text {
opacity: 0;
transition: all 1s ease-in;
}
#spinner-success-text.show {
opacity: 1;
}

If you add -Wl,--start-group
to the linker flags it does not care which order they're in or if there are circular dependencies.
On Qt this means adding:
QMAKE_LFLAGS += -Wl,--start-group
Saves loads of time messing about and it doesn't seem to slow down linking much (which takes far less time than compilation anyway).
If you need a specific exit status, Ansible provides a way to do that via callback plugins.
Example. It's a very good option if you need a 100% accurate exit status.
If not, you can always use the Debug Module, which is the standard for this cases of use.

You can convert a string to a DATE using the TO_DATE function, then reformat the date as another string using TO_CHAR, i.e.:
SELECT TO_CHAR(
TO_DATE('15/August/2009,4:30 PM'
,'DD/Month/YYYY,HH:MI AM')
,'DD-MM-YYYY')
FROM DUAL;
15-08-2009
For example, if your table name is MYTABLE and the varchar2 column is MYDATESTRING:
SELECT TO_CHAR(
TO_DATE(MYDATESTRING
,'DD/Month/YYYY,HH:MI AM')
,'DD-MM-YYYY')
FROM MYTABLE;
Try to change CREATE FUNCTION F_TEST(PID INT) RETURNS VARCHAR
this portion to
CREATE FUNCTION F_TEST(PID INT) RETURNS TEXT
and change the following line too.
DECLARE NAME_FOUND TEXT DEFAULT "";
It should work.
Here is the sample "Map" implementation in Go. Hope this helps!!

for index, val := range alist {
a[index] = f(val)
}
return a
}
func main() {
alist := []int{4, 5, 6, 7}
result := mapper(square, alist)
fmt.Println(result)
}
I usually use either komodo edit or aquamacs with ropemacs. Although I should warn you, IDE features won't be what you're used to if you're coming from a Java or C# background. I personally find that powerful IDEs get in my way more than they help.
UPDATE: I should also point out that if you have the money Komodo IDE is worth it. It's the paid version of Komodo Edit.
This is the most common technique I've seen:
function getUserIP() {
if( array_key_exists('HTTP_X_FORWARDED_FOR', $_SERVER) && !empty($_SERVER['HTTP_X_FORWARDED_FOR']) ) {
if (strpos($_SERVER['HTTP_X_FORWARDED_FOR'], ',')>0) {
$addr = explode(",",$_SERVER['HTTP_X_FORWARDED_FOR']);
return trim($addr[0]);
} else {
return $_SERVER['HTTP_X_FORWARDED_FOR'];
}
}
else {
return $_SERVER['REMOTE_ADDR'];
}
}
Note that it does not guarantee it you will get always the correct user IP because there are many ways to hide it.
If the purpose is to simply print coarse timing information to your program logs, then the easy solution for Java projects is not to write your own stopwatch or timer classes, but just use the org.apache.commons.lang.time.StopWatch
class that is part of Apache Commons Lang.
final StopWatch stopwatch = new StopWatch();
stopwatch.start();
LOGGER.debug("Starting long calculations: {}", stopwatch);
...
LOGGER.debug("Time after key part of calcuation: {}", stopwatch);
...
LOGGER.debug("Finished calculating {}", stopwatch);

Here's what I did in Linux to be able to program my Arduino Micro which was stuck in a loop sending the 0 key when connected by USB;
# while true; do xinput float $(xinput --list | grep -i Arduino | awk '{print $7}' | cut -d'=' -f 2); done
Your output might be slightly different so just try running;
# watch xinput --list
then plug in the Arduino and see how the output is formatted.
This stopped X from accepting the keypresses and allowed the Arduino IDE to program finally!

Use
document.body.innerHTML += '<div style="position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000;"></div>';
instead of
document.body.innerHTML = '<div style="position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000;"></div>';
Edit:-
Ideally you should use body.appendChild
method instead of changing the innerHTML
var elem = document.createElement('div');
elem.style.cssText = 'position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000';

After reading Java 7 Update 21 Security Improvements in Detail mention..
With the introduced changes it is most likely that no end-user is able to run your application when they are either self-signed or unsigned.
..I was wondering how this would go for loose class files - the 'simplest' applets of all.
![]()
Your security settings have blocked a local application from running
That is the dialog seen for an applet consisting of loose class files being loaded off the local file system when the JRE is set to the default 'High' security setting.
Note that a slight quirk of the JRE only produced that on point 3 of.
If you load the simple applet (loose class file) seen at this resizable applet demo off the internet - which boasts an applet
element of:
<applet
code="PlafChanger.class"
codebase="."
alt="Pluggable Look'n'Feel Changer appears here if Java is enabled"
width='100%'
height='250'>
<p>Pluggable Look'n'Feel Changer appears here in a Java capable browser.</p>
</applet>
It also seems to load successfully. Implying that:-
Applets loaded from the local file system are now subject to a stricter security sandbox than those loaded from the internet or a local server.
As of Java 7 update 51.
Please try this code along with the input field itself

I had this problem and it was because another script was deleting all of the tables and recreating them, but my table wasn't being recreated. I spent ages on this issue before I noticed that my table wasn't even visible on the page. Can you see your table before you initialize DataTables?
Essentially, the other script was doing:
let tables = $("table");
for (let i = 0; i < tables.length; i++) {
const table = tables[i];
if ($.fn.DataTable.isDataTable(table)) {
$(table).DataTable().destroy(remove);
$(table).empty();
}
}
And it should have been doing:
let tables = $("table.some-class-only");
... the rest ...
While the code to create a custom Attribute is fairly simple, it's very important that you understand what attributes are:
Attributes are metadata compiled into your program. Attributes themselves do not add any functionality to a class, property or module - just data. However, using reflection, one can leverage those attributes in order to create functionality.
So, for instance, let's look at the Validation Application Block, from Microsoft's Enterprise Library. If you look at a code example, you'll see:
/// <summary>
/// blah blah code.
/// </summary>
[DataMember]
[StringLengthValidator(8, RangeBoundaryType.Inclusive, 8, RangeBoundaryType.Inclusive, MessageTemplate = "\"{1}\" must always have \"{4}\" characters.")]
public string Code { get; set; }
From the snippet above, one might guess that the code will always be validated, whenever changed, accordingly to the rules of the Validator (in the example, have at least 8 characters and at most 8 characters). But the truth is that the Attribute does nothing; as mentioned previously, it only adds metadata to the property.
However, the Enterprise Library has a Validation.Validate
method that will look into your object, and for each property, it'll check if the contents violate the rule informed by the attribute.
So, that's how you should think about attributes -- a way to add data to your code that might be later used by other methods/classes/etc.
Precedence differs between && and and (&& has higher precedence than and), something that causes confusion when combined with a ternary operator. For instance,
$predA && $predB ? "foo" : "bar"
will return a string whereas
$predA and $predB ? "foo" : "bar"
will return a boolean.

You need to make sure the frame is fully loaded the best way to do it is to use onload:
<iframe id="nesgt" src="" onload="custom()"></iframe>
function custom(){
document.getElementById("nesgt").contentWindow.document;
}
this function will run automatically when the iframe is fully loaded.
it could be done with setTimeout but we can't get the exact time of the frame load.
hope this helps someone.
The below snippet works fine for me(I used the size())

System.out.println(itemId);

in fact. use the methods of vector and index. we can also achieve the same result, and more easier to understand:
rawdata <- data.frame('time' = 1:3,
'x1' = 4:6,
'x2' = 7:9,
'x3' = 10:12)
rawdata[rep(1, time=2), ] %>% remove_rownames()
# time x1 x2 x3
# 1 1 4 7 10
# 2 1 4 7 10
After set the spinner adapter this code will help
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
Toast.makeText(getApplicationContext(), "This is " +
adapterView.getItemAtPosition(i).toString(), Toast.LENGTH_LONG).show();
try {
//Your task here
}catch (Exception e)
{
e.printStackTrace();
}
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
Your idea of an hidden form element is solid. Something like this
<form action="script.php" method="post">
<input type="hidden" name="total" id="total">
</form>
<script type="text/javascript">
var element = document.getElementById("total");
element.value = getTotalFromSomewhere;
element.form.submit();
</script>
Of course, this will change the location to script.php
. If you want to do this invisibly to the user, you'll want to use AJAX. Here's a jQuery example (for brevity). No form or hidden inputs required
$.post("script.php", { total: getTotalFromSomewhere });
https://developer.mozilla.org/en/CSS/vertical-align
<table style="height: 275px; width: 188px">
<tr>
<td style="width: 259px; vertical-align:top">
main page
</td>
</tr>
</table>
?
I would like to suggest you the JQuery option.
$("#item").toggle();
$("#item").hide();
$("#item").show();
For example:
$(document).ready(function(){
$("#item").click(function(event){
//Your actions here
});
});
this looks like PHP to me. I'll delete if it's some other language.
Simply unset($arr[1]);
There is no answer on how to do this on CentOS. On Centos, you can add following to Dockerfile
RUN echo "user ALL=(root) NOPASSWD:ALL" > /etc/sudoers.d/user && \
chmod 0440 /etc/sudoers.d/user
this will work for sure..
RelativeLayout layout = new RelativeLayout(R.layout.your_layour);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.CENTER_IN_PARENT);
params.addRule(LinearLayout.CENTER_IN_PARENT);
textView.setLayoutParams(params);
textView.setGravity(Gravity.CENTER);
layout.addView(textView);
setcontentView(layout);
Stealing from @Lila (couldn't make a comment because of no formatting), this shows the module's /path/, as well:
#!/usr/bin/env python
import sys
from modulefinder import ModuleFinder
finder = ModuleFinder()
# Pass the name of the python file of interest
finder.run_script(sys.argv[1])
# This is what's different from @Lila's script
finder.report()
which produces:
Name File
---- ----
...
m token /opt/rh/rh-python35/root/usr/lib64/python3.5/token.py
m tokenize /opt/rh/rh-python35/root/usr/lib64/python3.5/tokenize.py
m traceback /opt/rh/rh-python35/root/usr/lib64/python3.5/traceback.py
...
.. suitable for grepping or what have you. Be warned, it's long!
Combination of lambda and map function can also do the job:
list_ = ['a', 'b', 'b', 'c']
sum(map(lambda x: x=="b", list_))

For the sake of completeness, isinstance will not work for type checking of a subtype that is not an instance. While that makes perfect sense, none of the answers (including the accepted one) covers it. Use issubclass for that.
>>> class a(list):
... pass
...
>>> isinstance(a, list)
False
>>> issubclass(a, list)
True
(Header CSS:)
<style>

Here is another way
timestamps.sort()
timestamps.reverse()
print(timestamps)
change your code to:
function ChangePurpose(Vid, PurId) {
var Success = false;
$.ajax({
type: "POST",
url: "CHService.asmx/SavePurpose",
dataType: "text",
async: false,
data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
contentType: "application/json; charset=utf-8",
success: function (data) {
Success = true;
},
error: function (textStatus, errorThrown) {
Success = false;
}
});
//done after here
return Success;
}
You can only return the values from a synchronous
function. Otherwise you will have to make a callback
.
So I just added async:false,
to your ajax call
Update:
jquery ajax calls are asynchronous by default. So success & error functions will be called when the ajax load is complete. But your return statement will be executed just after the ajax call is started.
A better approach will be:
// callbackfn is the pointer to any function that needs to be called
function ChangePurpose(Vid, PurId, callbackfn) {
var Success = false;
$.ajax({
type: "POST",
url: "CHService.asmx/SavePurpose",
dataType: "text",
data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
contentType: "application/json; charset=utf-8",
success: function (data) {
callbackfn(data)
},
error: function (textStatus, errorThrown) {
callbackfn("Error getting the data")
}
});
}
function Callback(data)
{
alert(data);
}
and call the ajax as:
// Callback is the callback-function that needs to be called when asynchronous call is complete
ChangePurpose(Vid, PurId, Callback);
Franci Penov's answer is certainly the best way to go so you always return items along with all additional metadata about your entities being requested. That's the way it should be done.
but sometimes returning all data doesn't make sense, because you may not need them at all. Maybe all you need is that metadata about your requested resource. Like total count or number of pages or something else. In such case you can always have URL query tell your service not to return items but rather just metadata like:
/api/members?metaonly=true
/api/members?includeitems=0
or something similar...
If you happen to be using the amqplib library as I am, they have a handy example of an implementation of the Publish/Subscribe RabbitMQ tutorial which you might find handy.
//auth required or redirect
app.use('/account', function(req, res, next) {
console.log(req.path);
if ( !req.session.user ) {
res.redirect('/login?ref='+req.path);
} else {
next();
}
});
req.path is / when it should be /account ??
The reason for this is that Express subtracts the path your handler function is mounted on, which is '/account'
in this case.
Why do they do this?
Because it makes it easier to reuse the handler function. You can make a handler function that does different things for req.path === '/'
and req.path === '/goodbye'
for example:
function sendGreeting(req, res, next) {
res.send(req.path == '/goodbye' ? 'Farewell!' : 'Hello there!')
}
Then you can mount it to multiple endpoints:
app.use('/world', sendGreeting)
app.use('/aliens', sendGreeting)
Giving:
/world ==> Hello there!
/world/goodbye ==> Farewell!
/aliens ==> Hello there!
/aliens/goodbye ==> Farewell!
I found this to work flawlessly if you want to share whole screen.
@IBAction func shareButton(_ sender: Any) {
let bounds = UIScreen.main.bounds
UIGraphicsBeginImageContextWithOptions(bounds.size, true, 0.0)
self.view.drawHierarchy(in: bounds, afterScreenUpdates: false)
let img = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
let activityViewController = UIActivityViewController(activityItems: [img!], applicationActivities: nil)
activityViewController.popoverPresentationController?.sourceView = self.view
self.present(activityViewController, animated: true, completion: nil)
}
In regards to the octal misinterpretation of .js - I just used this...
parseInt(parseFloat(nv))
and after testing with leading zeros, came back everytime with the correct representation.
hope this helps.
How do I properly compare strings?
char input[40];
char check[40];
strcpy(input, "Hello"); // input assigned somehow
strcpy(check, "Hello"); // check assigned somehow
// insufficient
while (check != input)
// good
while (strcmp(check, input) != 0)
// or
while (strcmp(check, input))
Let us dig deeper to see why check != input
is not sufficient.
In C, string is a standard library specification.
A string is a contiguous sequence of characters terminated by and including the first null character.
C11 §7.1.1 1
input
above is not a string. input
is array 40 of char.
The contents of input
can become a string.
In most cases, when an array is used in an expression, it is converted to the address of its 1st element.
The below converts check
and input
to their respective addresses of the first element, then those addresses are compared.
check != input // Compare addresses, not the contents of what addresses reference
To compare strings, we need to use those addresses and then look at the data they point to.
strcmp()
does the job. §7.23.4.2
int strcmp(const char *s1, const char *s2);
The
strcmp
function compares the string pointed to bys1
to the string pointed to bys2
.The
strcmp
function returns an integer greater than, equal to, or less than zero, accordingly as the string pointed to bys1
is greater than, equal to, or less than the string pointed to bys2
.
Not only can code find if the strings are of the same data, but which one is greater/less when they differ.
The below is true when the string differ.
strcmp(check, input) != 0
For insight, see Creating my own strcmp()
function
Setting the underlying socket ReceiveTimeout
property did the trick. You can access it like this: yourTcpClient.Client.ReceiveTimeout
. You can read the docs for more information.
Now the code will only "sleep" as long as needed for some data to arrive in the socket, or it will raise an exception if no data arrives, at the beginning of a read operation, for more than 20ms. I can tweak this timeout if needed. Now I'm not paying the 20ms price in every iteration, I'm only paying it at the last read operation. Since I have the content-length of the message in the first bytes read from the server I can use it to tweak it even more and not try to read if all expected data has been already received.
I find using ReceiveTimeout much easier than implementing asynchronous read... Here is the working code:
string SendCmd(string cmd, string ip, int port)
{
var client = new TcpClient(ip, port);
var data = Encoding.GetEncoding(1252).GetBytes(cmd);
var stm = client.GetStream();
stm.Write(data, 0, data.Length);
byte[] resp = new byte[2048];
var memStream = new MemoryStream();
var bytes = 0;
client.Client.ReceiveTimeout = 20;
do
{
try
{
bytes = stm.Read(resp, 0, resp.Length);
memStream.Write(resp, 0, bytes);
}
catch (IOException ex)
{
// if the ReceiveTimeout is reached an IOException will be raised...
// with an InnerException of type SocketException and ErrorCode 10060
var socketExept = ex.InnerException as SocketException;
if (socketExept == null || socketExept.ErrorCode != 10060)
// if it's not the "expected" exception, let's not hide the error
throw ex;
// if it is the receive timeout, then reading ended
bytes = 0;
}
} while (bytes > 0);
return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}
ResXResourceReader rsxr = new ResXResourceReader("your resource file path");
// Iterate through the resources and display the contents to the console.
foreach (DictionaryEntry d in rsxr)
{
Console.WriteLine(d.Key.ToString() + ":\t" + d.Value.ToString());
}
In your MakeFile or CMakeLists.txt you can set CMAKE_CXX_FLAGS as below:
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/path/to/your/folder")
Track the state of the connection yourself. With a boolean. Set it to false
at declaration. Use the various events (connect, disconnect, reconnect, etc.) to reassign the current boolean value. Note: Using undocumented API features (e.g., socket.connected
), is not a good idea; the feature could get removed in a subsequent version without the removal being mentioned.
You can just run:
git stash pop
and it will unstash your changes.
If you want to preserve the state of files (staged vs. working), use
git stash apply --index

This should work just fine for you, so long as the function jsonp_callback
is visible in the global scope:
function jsonp_callback(data) {
// returning from async callbacks is (generally) meaningless
console.log(data.found);
}
var url = "http://public-api.wordpress.com/rest/v1/sites/wtmpeachtest.wordpress.com/posts?callback=jsonp_callback";
$http.jsonp(url);
Full demo: http://jsfiddle.net/mattball/a4Rc2/ (disclaimer: I've never written any AngularJS code before)
After a lot of surfing, i found out the problem is GC overhead (out of memory). By adding below code to my build.gradle saved my day.
android {
dexOptions {
incremental = true;
preDexLibraries = false
javaMaxHeapSize "4g" // 2g should be also OK
}
}
reference - ProcessException: org.gradle.process.internal.ExecException finished with non-zero exit value 2
For anyone who wants to run private methods without all the fess and mess. This works with any unit testing framework using nothing but good old Reflection.
public class ReflectionTools
{
// If the class is non-static
public static Object InvokePrivate(Object objectUnderTest, string method, params object[] args)
{
Type t = objectUnderTest.GetType();
return t.InvokeMember(method,
BindingFlags.InvokeMethod |
BindingFlags.NonPublic |
BindingFlags.Instance |
BindingFlags.Static,
null,
objectUnderTest,
args);
}
// if the class is static
public static Object InvokePrivate(Type typeOfObjectUnderTest, string method, params object[] args)
{
MemberInfo[] members = typeOfObjectUnderTest.GetMembers(BindingFlags.NonPublic | BindingFlags.Static);
foreach(var member in members)
{
if (member.Name == method)
{
return typeOfObjectUnderTest.InvokeMember(method, BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.InvokeMethod, null, typeOfObjectUnderTest, args);
}
}
return null;
}
}
Then in your actual tests, you can do something like this:
Assert.AreEqual(
ReflectionTools.InvokePrivate(
typeof(StaticClassOfMethod),
"PrivateMethod"),
"Expected Result");
Assert.AreEqual(
ReflectionTools.InvokePrivate(
new ClassOfMethod(),
"PrivateMethod"),
"Expected Result");
I found the "cross module" answer above very helpful to my situation, but would want to expand on that, as there is another wrinkle to consider. If you have a submodule, it also can't see the pipes in the parent module in my testing. For that reason also, you may need to put pipes into there own separate module.
Here's a summary of the steps I took to address pipes not being visible in the submodule:
Another footnote to the above "cross module" answer: when I created the PipeModule I removed the forRoot static method and imported PipeModule without that in my shared module. My basic understanding is that forRoot is useful for scenarios like singletons, which don't apply to filters necessarily.
Thank you all for the answers. Here's my React + Recompose. It's a High Order Function that includes the windowHeight
and windowWidth
properties to the component.
const withDimensions = compose(
withStateHandlers(
({
windowHeight,
windowWidth
}) => ({
windowHeight: window.innerHeight,
windowWidth: window.innerWidth
}), {
handleResize: () => () => ({
windowHeight: window.innerHeight,
windowWidth: window.innerWidth
})
}),
lifecycle({
componentDidMount() {
window.addEventListener('resize', this.props.handleResize);
},
componentWillUnmount() {
window.removeEventListener('resize');
}})
)
Yes you can use them, for example I use them to more easily style groups of data, like this:
thead th { width: 100px; border-bottom: solid 1px #ddd; font-weight: bold; }_x000D_
tbody:nth-child(odd) { background: #f5f5f5; border: solid 1px #ddd; }_x000D_
tbody:nth-child(even) { background: #e5e5e5; border: solid 1px #ddd; }
_x000D_
<table>_x000D_
<thead>_x000D_
<tr><th>Customer</th><th>Order</th><th>Month</th></tr>_x000D_
</thead>_x000D_
<tbody>_x000D_
<tr><td>Customer 1</td><td>#1</td><td>January</td></tr>_x000D_
<tr><td>Customer 1</td><td>#2</td><td>April</td></tr>_x000D_
<tr><td>Customer 1</td><td>#3</td><td>March</td></tr>_x000D_
</tbody>_x000D_
<tbody>_x000D_
<tr><td>Customer 2</td><td>#1</td><td>January</td></tr>_x000D_
<tr><td>Customer 2</td><td>#2</td><td>April</td></tr>_x000D_
<tr><td>Customer 2</td><td>#3</td><td>March</td></tr>_x000D_
</tbody>_x000D_
<tbody>_x000D_
<tr><td>Customer 3</td><td>#1</td><td>January</td></tr>_x000D_
<tr><td>Customer 3</td><td>#2</td><td>April</td></tr>_x000D_
<tr><td>Customer 3</td><td>#3</td><td>March</td></tr>_x000D_
</tbody>_x000D_
</table>

You can view an example here. It'll only work in newer browsers, but that's what I'm supporting in my current application, you can use the grouping for JavaScript etc. The main thing is it's a convenient way to visually group the rows to make the data much more readable. There are other uses of course, but as far as applicable examples, this one is the most common one for me.
After trying the above suggestions, the only thing that worked for me was changing the border attribute to "0" in the following sections of a child theme's style.css (do a "Find" operation to locate each one -- the following are just snippets):
.comment-content table {
border-bottom: 1px solid #ddd;
.comment-content td {
border-top: 1px solid #ddd;
padding: 6px 10px 6px 0;
}
Thus looking like this afterwards:
.comment-content table {
border-bottom: 0;
.comment-content td {
border-top: 0;
padding: 6px 10px 6px 0;
}
If you need cryptographically-secure random numbers (e.g. for encryption), and you're in a browser, you can use the DOM cryptography API:
int random() {
final ary = new Int32Array(1);
window.crypto.getRandomValues(ary);
return ary[0];
}
This works in Dartium, Chrome, and Firefox, but likely not in other browsers as this is an experimental API.
I use the following function. Haven't checked benchmarks, but it works.
int msb(int num)
{
int m = 0;
for (int i = 16; i > 0; i = i>>1)
{
// debug(i, num, m);
if(num>>i)
{
m += i;
num>>=i;
}
}
return m;
}
One way using angular service:
var app = angular.module("home", []);
app.controller('one', function($scope, ser1){
$scope.inputText = ser1;
});
app.controller('two',function($scope, ser1){
$scope.inputTextTwo = ser1;
});
app.factory('ser1', function(){
return {o: ''};
});
<div ng-app='home'>
<div ng-controller='one'>
Type in text:
<input type='text' ng-model="inputText.o"/>
</div>
<br />
<div ng-controller='two'>
Type in text:
<input type='text' ng-model="inputTextTwo.o"/>
</div>
</div>
It works for me. The Java code works exactly as you wrote it. In the tester, the input string should be:
This is a string.
This is a long string.
...with a real linefeed. You can't use:
This is a string.\nThis is a long string.
...because it treats \n
as the literal sequence backslash 'n'.
From the point of view of making thinks simple, readable, consistent and easy to understand (since performance doesn't matter here):
Using embedded vars in double quotes can lead to complex and confusing situations when you want to embed object properties, multidimentional arrays etc. That is, generally when reading embedded vars, you cannot be instantly 100% sure of the final behavior of what you are reading.
You frequently need add crutches such as {}
and \
, which IMO adds confusion and makes concatenation readability nearly equivalent, if not better.
As soon as you need to wrap a function call around the var, for example htmlspecialchars($var)
, you have to switch to concatenation.
AFAIK, you cannot embed constants.
In some specific cases, "double quotes with vars embedding" can be useful, but generally speaking, I would go for concatenation (using single or double quotes when convenient)
The file extension .img
does not say anything about its content.
Most commonly .img files are a floppy/CD/DVD/ISO image, a filesystem image, a disk image, or even just (custom) binary data.
In case it is an CD/DVD image or a specific filesystem image (like fat, ntfs, ...) you can open these files with 7-Zip.
On *nix based systems also the file
tool or (libmagic) could help you find out what it is.
The best you can get with simple styles would be something like:
.likeabutton {
text-decoration: none; font: menu;
display: inline-block; padding: 2px 8px;
background: ButtonFace; color: ButtonText;
border-style: solid; border-width: 2px;
border-color: ButtonHighlight ButtonShadow ButtonShadow ButtonHighlight;
}
.likeabutton:active {
border-color: ButtonShadow ButtonHighlight ButtonHighlight ButtonShadow;
}
(Possibly with some kind of fix to stop IE6-IE7 treating focused buttons as being ‘active’.)
This won't necessarily look exactly like the buttons on the native desktop, though; indeed, for many desktop themes it won't be possible to reproduce the look of a button in simple CSS.
However, you can ask the browser to use native rendering, which is best of all:
.likeabutton {
appearance: button;
-moz-appearance: button;
-webkit-appearance: button;
text-decoration: none; font: menu; color: ButtonText;
display: inline-block; padding: 2px 8px;
}
Unfortunately, as you may have guessed from the browser-specific prefixes, this is a CSS3 feature that isn't suppoorted everywhere yet. In particular IE and Opera will ignore it. But if you include the other styles as backup, the browsers that do support appearance
drop that property, preferring the explicit backgrounds and borders!
What you might do is use the appearance
styles as above by default, and do JavaScript fixups as necessary, eg.:
<script type="text/javascript">
var r= document.documentElement;
if (!('appearance' in r || 'MozAppearance' in r || 'WebkitAppearance' in r)) {
// add styles for background and border colours
if (/* IE6 or IE7 */)
// add mousedown, mouseup handlers to push the button in, if you can be bothered
else
// add styles for 'active' button
}
</script>
All the answers here are great but, just to illustrate where this comes from, for questions like this it's good to go to the source: the Java Language Specification.
Section 15:23, Conditional-And operator (&&), says:
The && operator is like & (§15.22.2), but evaluates its right-hand operand only if the value of its left-hand operand is true. [...] At run time, the left-hand operand expression is evaluated first [...] if the resulting value is false, the value of the conditional-and expression is false and the right-hand operand expression is not evaluated. If the value of the left-hand operand is true, then the right-hand expression is evaluated [...] the resulting value becomes the value of the conditional-and expression. Thus, && computes the same result as & on boolean operands. It differs only in that the right-hand operand expression is evaluated conditionally rather than always.
And similarly, Section 15:24, Conditional-Or operator (||), says:
The || operator is like | (§15.22.2), but evaluates its right-hand operand only if the value of its left-hand operand is false. [...] At run time, the left-hand operand expression is evaluated first; [...] if the resulting value is true, the value of the conditional-or expression is true and the right-hand operand expression is not evaluated. If the value of the left-hand operand is false, then the right-hand expression is evaluated; [...] the resulting value becomes the value of the conditional-or expression. Thus, || computes the same result as | on boolean or Boolean operands. It differs only in that the right-hand operand expression is evaluated conditionally rather than always.
A little repetitive, maybe, but the best confirmation of exactly how they work. Similarly the conditional operator (?:) only evaluates the appropriate 'half' (left half if the value is true, right half if it's false), allowing the use of expressions like:
int x = (y == null) ? 0 : y.getFoo();
without a NullPointerException.
use DECIMAL()
or NUMERIC()
as they are fixed precision and scale numbers.
SELECT fullName,
CAST(totalBal as DECIMAL(9,2)) _totalBal
FROM client_info
ORDER BY _totalBal DESC
Maybe this will help:
<select onchange="location = this.value;">
<option value="home.html">Home</option>
<option value="contact.html">Contact</option>
<option value="about.html">About</option>
</select>
I was having the same problem, although I solved out by creating the table using a script query instead of doing it graphically. See the snipped below:
USE [Database_Name]
GO
CREATE TABLE [dbo].[Table_Name](
[tableID] [int] IDENTITY(1,1) NOT NULL,
[column_2] [datatype] NOT NULL,
[column_3] [datatype] NOT NULL,
CONSTRAINT [PK_Table_Name] PRIMARY KEY CLUSTERED
(
[tableID] ASC
)
)
When specifying your cron values you'll need to make sure that your values fall within the ranges. For instance, some cron's use a 0-7 range for the day of week where both 0 and 7 represent Sunday. We do not(check below).
Seconds: 0-59
Minutes: 0-59
Hours: 0-23
Day of Month: 1-31
Months: 0-11
Day of Week: 0-6

I will do something like this:
List<String> order = List.of("Red", "Green", "Magenta", "Silver");
Comparator.comparing(Car::getColor(), Comparator.comparingInt(c -> order.indexOf(c)))

UI:
It looks like Angular has support for this now.
From the latest (v1.2.0) docs for $routeProvider.when(path, route)
:
path
can contain optional named groups with a question mark (:name?
)
Usually I wrap the output into a list, which is very flexible (you can have any combination of numbers, strings, vectors, matrices, arrays, lists, objects int he output)
so like:
func2<-function(input) {
a<-input+1
b<-input+2
output<-list(a,b)
return(output)
}
output<-func2(5)
for (i in output) {
print(i)
}
[1] 6
[1] 7
From the documentation:
We can add to a list in many ways:
assert [1,2] + 3 + [4,5] + 6 == [1, 2, 3, 4, 5, 6]
assert [1,2].plus(3).plus([4,5]).plus(6) == [1, 2, 3, 4, 5, 6]
//equivalent method for +
def a= [1,2,3]; a += 4; a += [5,6]; assert a == [1,2,3,4,5,6]
assert [1, *[222, 333], 456] == [1, 222, 333, 456]
assert [ *[1,2,3] ] == [1,2,3]
assert [ 1, [2,3,[4,5],6], 7, [8,9] ].flatten() == [1, 2, 3, 4, 5, 6, 7, 8, 9]
def list= [1,2]
list.add(3) //alternative method name
list.addAll([5,4]) //alternative method name
assert list == [1,2,3,5,4]
list= [1,2]
list.add(1,3) //add 3 just before index 1
assert list == [1,3,2]
list.addAll(2,[5,4]) //add [5,4] just before index 2
assert list == [1,3,5,4,2]
list = ['a', 'b', 'z', 'e', 'u', 'v', 'g']
list[8] = 'x'
assert list == ['a', 'b', 'z', 'e', 'u', 'v', 'g', null, 'x']
You can also do:
def myNewList = myList << "fifth"
Or maybe just use conditional chains with ternary operator. if … else if … else if … else
chain.

From the docs
Bitcode will allow apple to optimise the app without you having to submit another build. But, you can only enable this feature if all frameworks and apps in the app bundle have this feature enabled. Having it helps, but not having it should not have any negative impact.
For iOS apps, bitcode is the default, but optional. If you provide bitcode, all apps and frameworks in the app bundle need to include bitcode. For watchOS apps, bitcode is required.
The App Store and operating system optimize the installation of iOS and watchOS apps by tailoring app delivery to the capabilities of the user’s particular device, with minimal footprint. This optimization, called app thinning, lets you create apps that use the most device features, occupy minimum disk space, and accommodate future updates that can be applied by Apple. Faster downloads and more space for other apps and content provides a better user experience.
There should not be any performance impacts.
In our case the problem was that we change the default root namespace name.
This is the Project Configuration screen
We finally decided to back to the original name and the problem was solved.
The problem actually was the dots in the Root namespace. With two dots (Name.Child.Child) it doesnt work. But with one (Name.ChidChild) works.
you can use
moviesTitles.map((title) => Tab(text: title)).toList()
example:
bottom: new TabBar(
controller: _controller,
isScrollable: true,
tabs:
moviesTitles.map((title) => Tab(text: title)).toList()
,
),
Trey Hunner has a nice blog post outlining several options for merging multiple dictionaries, including (for python3.3+) ChainMap and dictionary unpacking.
This is for others (like me :) ). Don't forget to add the spring tx jar/maven dependency. Also correct configuration in appctx is:
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd"
, by mistake wrong configuration which others may have
xmlns:tx="http://www.springframework.org/schema/tx/spring-tx-3.1.xsd"
i.e., extra "/spring-tx-3.1.xsd"
xsi:schemaLocation="http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd"
in other words what is there in xmlns(namespace) should have proper mapping in
schemaLocation (namespace vs schema).
namespace here is : http://www.springframework.org/schema/tx
schema Doc Of namespace is : http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
this schema of namespace later is mapped in jar to locate the path of actual xsd located in org.springframework.transaction.config
I assume you are using ASP.NET MVC (C#), if not then this answer is not in your issue.
Is it impossible to assign session values directly through javascript? No, there is a way to do that.
Look again your code:
<script type="text/javascript" >
{
Session["controlID"] ="This is my session";
}
</script>
A little bit change:
<script type="text/javascript" >
{
<%Session["controlID"] = "This is my session";%>
}
</script>
The session "controlID" has created, but what about the value of session? is that persistent or can changeable via javascript?
Let change a little bit more:
<script type="text/javascript" >
{
var strTest = "This is my session";
<%Session["controlID"] = "'+ strTest +'";%>
}
</script>
The session is created, but the value inside of session will be "'+ strTest +'" but not "This is my session". If you try to write variable directly into server code like:
<%Session["controlID"] = strTest;%>
Then an error will occur in you page "There is no parameter strTest in current context...". Until now it is still seem impossible to assign session values directly through javascript.
Now I move to a new way. Using WebMethod at code behind to do that. Look again your code with a little bit change:
<script type="text/javascript" >
{
var strTest = "This is my session";
PageMethods.CreateSessionViaJavascript(strTest);
}
</script>
In code-behind page. I create a WebMethod:
[System.Web.Services.WebMethod]
public static string CreateSessionViaJavascript(string strTest)
{
Page objp = new Page();
objp.Session["controlID"] = strTest;
return strTest;
}
After call the web method to create a session from javascript. The session "controlID" will has value "This is my session".
If you use the way I have explained, then please add this block of code inside form tag of your aspx page. The code help to enable page methods.
<asp:ScriptManager EnablePageMethods="true" ID="MainSM" runat="server" ScriptMode="Release" LoadScriptsBeforeUI="true"></asp:ScriptManager>

Since PyYAML's yaml.load()
function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:
import yaml
with open('tree.yaml', 'r') as f:
doc = yaml.load(f)
To access branch1 text
you would use:
txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"
because, in your YAML document, the value of the branch1
key is under the treeroot
key.
To clear Application Data Please Try this way.
public void clearApplicationData() {
File cache = getCacheDir();
File appDir = new File(cache.getParent());
if (appDir.exists()) {
String[] children = appDir.list();
for (String s : children) {
if (!s.equals("lib")) {
deleteDir(new File(appDir, s));Log.i("TAG", "**************** File /data/data/APP_PACKAGE/" + s + " DELETED *******************");
}
}
}
}
public static boolean deleteDir(File dir) {
if (dir != null && dir.isDirectory()) {
String[] children = dir.list();
for (int i = 0; i < children.length; i++) {
boolean success = deleteDir(new File(dir, children[i]));
if (!success) {
return false;
}
}
}
return dir.delete();
}

You need to add Portrait (top home button) on the supported interface orientation field of info.plist file in xcode
You don't need jQuery to achieve this. In your form add:
onsubmit="return buttonSubmit(this)
or in JavaScript:
myform.setAttribute("onsubmit", "return buttonSubmit(this)");
In your buttonSubmit
function (or whatver you call it), you can submit the form using AJAX. buttonSubmit
will only get called if your form is validated in HTML5.
In case this helps anyone, here is my buttonSubmit
function:
function buttonSubmit(e)
{
var ajax;
var formData = new FormData();
for (i = 0; i < e.elements.length; i++)
{
if (e.elements[i].type == "submit")
{
if (submitvalue == e.elements[i].value)
{
submit = e.elements[i];
submit.disabled = true;
}
}
else if (e.elements[i].type == "radio")
{
if (e.elements[i].checked)
formData.append(e.elements[i].name, e.elements[i].value);
}
else
formData.append(e.elements[i].name, e.elements[i].value);
}
formData.append("javascript", "javascript");
var action = e.action;
status = action.split('/').reverse()[0] + "-status";
ajax = new XMLHttpRequest();
ajax.addEventListener("load", manageLoad, false);
ajax.addEventListener("error", manageError, false);
ajax.open("POST", action);
ajax.send(formData);
return false;
}
Some of my forms contain multiple submit buttons, hence this line if (submitvalue == e.elements[i].value)
. I set the value of submitvalue
using a click event.
Lot's of great answer. I just want to add a small note about decoupling the stream.
cin.tie(NULL);
I have faced an issue while decoupling the stream with CodeChef platform. When I submitted my code, the platform response was "Wrong Answer" but after tying the stream and testing the submission. It worked.
So, If anyone wants to untie the stream, the output stream must be flushed.
Edit: I am not familiar with all the platform but this is what I have experienced.
The path to the SDK is:
C:\Users\USERNAME\AppData\Local\Android\sdk
This can be used in Eclipse after you replace USERNAME with your Windows user name.
for regular Joins, it doesn't. TableA join TableB
will produce the same execution plan as TableB join TableA
(so your C and D examples would be the same)
for left and right joins it does. TableA left Join TableB
is different than TableB left Join TableA
, BUT its the same than TableB right Join TableA

The Best way and recommended way of comparing date in typescript
is:
var today = new Date().getTime();
var reqDateVar = new Date(somedate).getTime();
if(today === reqDateVar){
// NOW
} else {
// Some other time
}
Blob URLs (ref W3C, official name) or Object-URLs (ref. MDN and method name) are used with a Blob or a File object.
src="blob:https://crap.crap" I opened the blob url that was in src of video it gave a error and i can't open but was working with the src tag how it is possible?
Blob URLs can only be generated internally by the browser. URL.createObjectURL()
will create a special reference to the Blob or File object which later can be released using URL.revokeObjectURL()
. These URLs can only be used locally in the single instance of the browser and in the same session (ie. the life of the page/document).
What is blob url?
Why it is used?
Blob URL/Object URL is a pseudo protocol to allow Blob and File objects to be used as URL source for things like images, download links for binary data and so forth.
For example, you can not hand an Image object raw byte-data as it would not know what to do with it. It requires for example images (which are binary data) to be loaded via URLs. This applies to anything that require an URL as source. Instead of uploading the binary data, then serve it back via an URL it is better to use an extra local step to be able to access the data directly without going via a server.
It is also a better alternative to Data-URI which are strings encoded as Base-64. The problem with Data-URI is that each char takes two bytes in JavaScript. On top of that a 33% is added due to the Base-64 encoding. Blobs are pure binary byte-arrays which does not have any significant overhead as Data-URI does, which makes them faster and smaller to handle.
Can i make my own blob url on a server?
No, Blob URLs/Object URLs can only be made internally in the browser. You can make Blobs and get File object via the File Reader API, although BLOB just means Binary Large OBject and is stored as byte-arrays. A client can request the data to be sent as either ArrayBuffer or as a Blob. The server should send the data as pure binary data. Databases often uses Blob to describe binary objects as well, and in essence we are talking basically about byte-arrays.
if you have then Additional detail
You need to encapsulate the binary data as a BLOB object, then use URL.createObjectURL()
to generate a local URL for it:
var blob = new Blob([arrayBufferWithPNG], {type: "image/png"}),
url = URL.createObjectURL(blob),
img = new Image();
img.onload = function() {
URL.revokeObjectURL(this.src); // clean-up memory
document.body.appendChild(this); // add image to DOM
}
img.src = url; // can now "stream" the bytes
Note that URL
may be prefixed in webkit-browsers, so use:
var url = (URL || webkitURL).createObjectURL(...);
deleteRequest: function (url, Id, bolDeleteReq, callback, errorCallback) {
$.ajax({
url: urlCall,
type: 'DELETE',
data: {"Id": Id, "bolDeleteReq" : bolDeleteReq},
success: callback || $.noop,
error: errorCallback || $.noop
});
}
Note: the use of headers
was introduced in JQuery 1.5.:
A map of additional header key/value pairs to send along with the request. This setting is set before the beforeSend function is called; therefore, any values in the headers setting can be overwritten from within the beforeSend function.
Well for one thing use int.TryParse instead...
int id;
if (!int.TryParse(Request.QueryString["id"], out id))
{
id = -1;
}
That assumes that "not present" should have the same result as "not an integer" of course.
EDIT: In other cases, when you're going to use request parameters as strings anyway, I think it's definitely a good idea to validate that they're present.
I'm new in R, but I was using this easy method that works for me:
sample_of_diamonds <- diamonds[sample(nrow(diamonds),100),]
PS: Feel free to note if it has some drawback I'm not thinking about.

Assemblies are a good option for you. There are a lot of sites that explain how to create it. The one I think is very well explained is this one
If you want, I have already created the assembly, and it is possible to download the DLL here.
Once you have downloaded it, you will need to run the following script in your SQL Server:
EXEC sp_configure 'show advanced options', 1
RECONFIGURE;
EXEC sp_configure 'clr strict security', 1;
RECONFIGURE;
CREATE Assembly concat_assembly
AUTHORIZATION dbo
FROM '<PATH TO Concat.dll IN SERVER>'
WITH PERMISSION_SET = SAFE;
GO
CREATE AGGREGATE dbo.concat (
@Value NVARCHAR(MAX)
, @Delimiter NVARCHAR(4000)
) RETURNS NVARCHAR(MAX)
EXTERNAL Name concat_assembly.[Concat.Concat];
GO
sp_configure 'clr enabled', 1;
RECONFIGURE
Observe that the path to assembly may be accessible to server. Since you have successfully done all the steps, you can use the function like:
SELECT dbo.Concat(field1, ',')
FROM Table1
Hope it helps!!!
UPDATE:
Since MS-SQL 2017 it is possible to use the STRING_AGG function
Ben Carp solution in typescript
React 16.8 + Functional component - useFocus hook
export const useFocus = (): [React.MutableRefObject<HTMLInputElement>, VoidFunction] => {
const htmlElRef = React.useRef<HTMLInputElement>(null);
const setFocus = React.useCallback(() => {
if (htmlElRef.current) htmlElRef.current.focus();
}, [htmlElRef]);
return React.useMemo(() => [htmlElRef, setFocus], [htmlElRef, setFocus]);
};
You can probably use
new Date().setUTCHours(0,0,0,0)
if you need the value only once.
On Logout from the Client Side, the easiest way is to remove the token from the storage of browser.
But, What if you want to destroy the token on the Node server -
The problem with JWT package is that it doesn't provide any method or way to destroy the token.
So in order to destroy the token on the serverside you may use jwt-redis package instead of JWT
This library (jwt-redis) completely repeats the entire functionality of the library jsonwebtoken, with one important addition. Jwt-redis allows you to store the token label in redis to verify validity. The absence of a token label in redis makes the token not valid. To destroy the token in jwt-redis, there is a destroy method
it works in this way :
1) Install jwt-redis from npm
2) To Create -
var redis = require('redis');
var JWTR = require('jwt-redis').default;
var redisClient = redis.createClient();
var jwtr = new JWTR(redisClient);
jwtr.sign(payload, secret)
.then((token)=>{
// your code
})
.catch((error)=>{
// error handling
});
3) To verify -
jwtr.verify(token, secret);
4) To Destroy -
jwtr.destroy(token)
Note : you can provide expiresIn during signin of token in the same as it is provided in JWT.
If you want to include into your code and not use the IntentIntegrator that the ZXing library recommend, you can use some of these ports:
I use the first, and it works perfectly! It has a sample project to try it on.

Go to Python X.X/Lib
and add these lines to the site.py
there,
import sys
sys.path.append("yourpathstring")
This changes your sys.path
so that on every load, it will have that value in it..
As stated here about site.py
,
This module is automatically imported during initialization. Importing this module will append site-specific paths to the module search path and add a few builtins.
For other possible methods of adding some path to sys.path
see these docs
If you are adding a loading view (an activity indicator view for instance), make sure you have an object of UIWindow class. If you show an action sheet just before you show your loading view, the keyWindow
will be the UIActionSheet
and not UIWindow
. And since the action sheet will go away, the loading view will go away with it. Or that's what was causing me problems.
UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow];
if (![NSStringFromClass([keyWindow class]) isEqualToString:@"UIWindow"]) {
// find uiwindow in windows
NSArray *windows = [UIApplication sharedApplication].windows;
for (UIWindow *window in windows) {
if ([NSStringFromClass([window class]) isEqualToString:@"UIWindow"]) {
keyWindow = window;
break;
}
}
}
One more alternative, in the case you are working with the Appstore, need "Entitlements" and as such need to link with an Apple-Framework.
For Entitlements to work (e.g. GameCenter) you need to have a "Link Binary with Libraries"-buildstep and then link with "GameKit.framework". CMake "injects" the libraries on a "low level" into the commandline, hence Xcode doesn't really know about it, and as such you will not get GameKit enabled in the Capabilities screen.
One way to use CMake and have a "Link with Binaries"-buildstep is to generate the xcodeproj with CMake, and then use 'sed' to 'search & replace' and add the GameKit in the way XCode likes it...
The script looks like this (for Xcode 6.3.1).

save this to "gamecenter.sed" and then "apply" it like this ( it changes your xcodeproj! )
sed -i.pbxprojbak -f gamecenter.sed myproject.xcodeproj/project.pbxproj
You might have to change the script-commands to fit your need.
Warning: it's likely to break with different Xcode-version as the project-format could change, the (hardcoded) unique number might not really by unique - and generally the solutions by other people are better - so unless you need to Support the Appstore + Entitlements (and automated builds), don't do this.
This is a CMake bug, see http://cmake.org/Bug/view.php?id=14185 and http://gitlab.kitware.com/cmake/cmake/issues/14185
Using testflight :
1) create the ipa file by development certificate
2) upload the ipa file on testflight
3) Now, to identify the device to be tested on , add the device id on apple account and refresh your development certificate. Download the updated certificate and upload it on testflight website. Check the device id you are getting.
4) Now email the ipa file to the testers.
5) While downloading the ipa file, if the testers are not getting any warnings, this means the device token + provisioning profile has been verified. So, the testers can now download the ipa file on device and do the testing job...
Why not just make the access_token last as long as the refresh_token and not have a refresh_token?
In addition to great answers other people have provided, there is another reason why we would use refresh tokens and it's to do with claims.
Each token contains claims which can include anything from the user's name, their roles, or the provider which created the claim. As a token is refreshed, these claims are updated.
If we refresh the tokens more often, we are obviously putting more strain on our identity services; however, we are getting more accurate and up-to-date claims.

Below is example to call synchronously but you can easily change to async by using await-sync:
var pairs = new List<KeyValuePair<string, string>>
{
new KeyValuePair<string, string>("login", "abc")
};
var content = new FormUrlEncodedContent(pairs);
var client = new HttpClient {BaseAddress = new Uri("http://localhost:6740")};
// call sync
var response = client.PostAsync("/api/membership/exist", content).Result;
if (response.IsSuccessStatusCode)
{
}
The echo
solution adds new lines whenever IFS
breaks the input stream. @fgm's answer can be modified a bit:
cat "${1:-/dev/stdin}" > "${2:-/dev/stdout}"
You have to override method handledType and everything will work
@Override
public Class<Item> handledType()
{
return Item.class;
}
for me the problem was in Other Linker flags value. For some reason I had no quotes in flags like -l"xml2"
-l"Pods-MBProgressHUD"
.
You don't need to download any new software. You can use Octave Online to open .m files.

You can do it without using box-sizing
and not clear solutions like width~=99%
.

padding
equal to margin
from previous stepHTML markup:
<div class="input_wrap">

May be this will help some one. I have my proxy setup in python script but keep getting the error mentioned in the question.
Below is the piece of block which will take my username and password as a constant in the beginning.
if (use_proxy):
proxy = req.ProxyHandler({'https': proxy_url})
auth = req.HTTPBasicAuthHandler()
opener = req.build_opener(proxy, auth, req.HTTPHandler)
req.install_opener(opener)
If you are using corporate laptop and if you did not connect to Direct Access or office VPN then the above block will throw error. All you need to do is to connect to your org VPN and then execute your python script.
Thanks
The major difference between Page_Load
and Page_PreRender
is that in the Page_Load method not all of your page controls are completely initialized (loaded), because individual controls Load()
methods has not been called yet. This means that tree is not ready for rendering yet. In Page_PreRender
you guaranteed that all page controls are loaded and ready for rendering. Technically Page_PreRender
is your last chance to tweak the page before it turns into HTML stream.
Here's some JavaScript for copy-paste ease (this is irritate's answer):
function scaleBetween(unscaledNum, minAllowed, maxAllowed, min, max) {
return (maxAllowed - minAllowed) * (unscaledNum - min) / (max - min) + minAllowed;
}
Applied like so, scaling the range 10-50 to a range between 0-100.
var unscaledNums = [10, 13, 25, 28, 43, 50];
var maxRange = Math.max.apply(Math, unscaledNums);
var minRange = Math.min.apply(Math, unscaledNums);
for (var i = 0; i < unscaledNums.length; i++) {
var unscaled = unscaledNums[i];
var scaled = scaleBetween(unscaled, 0, 100, minRange, maxRange);
console.log(scaled.toFixed(2));
}
0.00, 18.37, 48.98, 55.10, 85.71, 100.00
Edit:
I know I answered this a long time ago, but here's a cleaner function that I use now:
Array.prototype.scaleBetween = function(scaledMin, scaledMax) {
var max = Math.max.apply(Math, this);
var min = Math.min.apply(Math, this);
return this.map(num => (scaledMax-scaledMin)*(num-min)/(max-min)+scaledMin);
}
Applied like so:
[-4, 0, 5, 6, 9].scaleBetween(0, 100);
[0, 30.76923076923077, 69.23076923076923, 76.92307692307692, 100]
Having learned of this feature only just now while reading your question, I can only speculate. This seems to provide several advantages over a file-level static variable:
I'd be interested in learning if anyone has used anonymous namespaces in real code.
$var = mysql_real_escape_string("data & the base");
$result = mysql_query('SELECT * FROM php_bugs WHERE php_bugs_category like "%' .$var.'%"');
@albert's solution was the closest I think but it can only parse up to 3 byte utf-8 characters
function utf8ArrayToStr(array) {
var out, i, len, c;
var char2, char3;
out = "";
len = array.length;
i = 0;
// XXX: Invalid bytes are ignored
while(i < len) {
c = array[i++];
if (c >> 7 == 0) {
// 0xxx xxxx
out += String.fromCharCode(c);
continue;
}
// Invalid starting byte
if (c >> 6 == 0x02) {
continue;
}
// #### MULTIBYTE ####
// How many bytes left for thus character?
var extraLength = null;
if (c >> 5 == 0x06) {
extraLength = 1;
} else if (c >> 4 == 0x0e) {
extraLength = 2;
} else if (c >> 3 == 0x1e) {
extraLength = 3;
} else if (c >> 2 == 0x3e) {
extraLength = 4;
} else if (c >> 1 == 0x7e) {
extraLength = 5;
} else {
continue;
}
// Do we have enough bytes in our data?
if (i+extraLength > len) {
var leftovers = array.slice(i-1);
// If there is an invalid byte in the leftovers we might want to
// continue from there.
for (; i < len; i++) if (array[i] >> 6 != 0x02) break;
if (i != len) continue;
// All leftover bytes are valid.
return {result: out, leftovers: leftovers};
}
// Remove the UTF-8 prefix from the char (res)
var mask = (1 << (8 - extraLength - 1)) - 1,
res = c & mask, nextChar, count;
for (count = 0; count < extraLength; count++) {
nextChar = array[i++];
// Is the char valid multibyte part?
if (nextChar >> 6 != 0x02) {break;};
res = (res << 6) | (nextChar & 0x3f);
}
if (count != extraLength) {
i--;
continue;
}
if (res <= 0xffff) {
out += String.fromCharCode(res);
continue;
}
res -= 0x10000;
var high = ((res >> 10) & 0x3ff) + 0xd800,
low = (res & 0x3ff) + 0xdc00;
out += String.fromCharCode(high, low);
}
return {result: out, leftovers: []};
}
This returns {result: "parsed string", leftovers: [list of invalid bytes at the end]}
in case you are parsing the string in chunks.
EDIT: fixed the issue that @unhammer found.
I'm the developer of Redux Auth and some of the issues you mentioned have been fixed in the version 2 beta. You can download this off the offcial website with a sample application too.
- Requires autoloading (impeding performance)
- Uses the inherently unsafe concept of 'security questions'. Dealbreaker!
Security questions are now not used and a simpler forgotten password system has been put in place.
- Return types are a bit of a hodgepodge of true, false, error and success codes
This was fixed in version 2 and returns boolean values. I hated the hodgepodge as much as you.
- Doesn't hook into CI's validation system
The sample application uses the CI's validation system.
- Doesn't allow a user to resend a 'lost password' code
Work in progress
I also implemented some other features such as email views, this gives you the choice of being able to use the CodeIgniter helpers in your emails.
It's still a work in progress so if have any more suggestions please keep them coming.

Ps : Thanks for recommending Redux.

Is there a method equivalent to getJSONArray in org.json so that I have proper error handling in case it isn't an array?
It depends on your input; i.e. the stuff you fetch from the URL. If the value of the "datasets" attribute is an associative array rather than a plain array, you will get a ClassCastException
.
But then again, the correctness of your old version also depends on the input. In the situation where your new version throws a ClassCastException
, the old version will throw JSONException
. Reference: http://www.json.org/javadoc/org/json/JSONObject.html#getJSONArray(java.lang.String)
You can grab the command line of any .Net application by accessing the Environment.CommandLine property. It will have the command line as a single string but parsing out the data you are looking for shouldn't be terribly difficult.
Having an empty Main method will not affect this property or the ability of another program to add a command line parameter.
I faced the same problem in eclipse with tomcat7 with the error javax.servlet cannot be resolved. If I select the server in targeted runtime mode and build project again, the error get's resolved.
you can't assign an event by string. Use that:
elemm.onclick = function(){ alert('blah'); };
You could also organise them into modules. So it would be something like.
./
controllers
index.js
indexController.js
app.js
and then in the indexController.js of the controllers export your controllers.
//indexController.js
module.exports = function(){
//do some set up
var self = {
indexAction : function (req,res){
//do your thing
}
return self;
};
then in index.js of controllers dir
exports.indexController = require("./indexController");
and finally in app.js
var controllers = require("./controllers");
app.get("/",controllers.indexController().indexAction);
I think this approach allows for clearer seperation and also you can configure your controllers by passing perhaps a db connection in.
I tried all the solutions but it still wasn't sufficient. After some more digging I eventually found I had also to set the 'file_priv' flag, and restart mysql.
To resume :
Grant the privileges :
> GRANT ALL PRIVILEGES
ON my_database.*
to 'my_user'@'localhost';
> GRANT FILE ON *.* TO my_user;
> FLUSH PRIVILEGES;
Set the flag :
> UPDATE mysql.user SET File_priv = 'Y' WHERE user='my_user' AND host='localhost';
Finally restart the mysql server:
$ sudo service mysql restart
After that, I could write into the secure_file_priv
directory. For me it was /var/lib/mysql-files/, but you can check it with the following command :
> SHOW VARIABLES LIKE "secure_file_priv";
this can be achieved with the css calc()
operator
@media screen and (min-width: 480px) {
body {
background-color: lightgreen;
zoom:calc(100% / 480);
}
}
It's called and
and or
in Python.
Use the -I
flag to gcc properly.
gcc -I/path/to/openssl/ -o Opentest -lcrypto Opentest.c
The -I
should point to the directory containing the openssl
folder.
I had this issue as well, and the text-shadow
wasn't an option because the corners would look bad (unless I had many many shadows), and I didn't want any blur, therefore my only other option was to do the following: Have 2 divs, and for the background div, put a -webkit-text-stroke
on it, which then allows for as big of an outline as you like.
div {_x000D_
font-size: 200px;_x000D_
position: absolute;_x000D_
white-space: nowrap;_x000D_
}_x000D_
_x000D_
.front {_x000D_
color: blue;_x000D_
}_x000D_
_x000D_
.outline {_x000D_
-webkit-text-stroke: 30px red;_x000D_
user-select: none;_x000D_
}
_x000D_
<div class="outline">_x000D_
outline text_x000D_
</div>_x000D_
_x000D_
<div class="front">_x000D_
outline text_x000D_
</div>
_x000D_
Using this, I was able to achieve an outline, because the stroke-width
method was not an option if you want your text to remain legible with a very large outline (because with stroke-width
the outline will start inside the lettering which makes it not legible when the width gets larger than the letters.
Note: the reason I needed such a fat outline was I was emulating the street labels in "google maps" and I wanted a fat white halo around the text. This solution worked perfectly for me.
I got similar error (org.aspectj.apache.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 15) while using aspectj 1.8.13. Solution was to align all compilation into jdk 8 and being careful not to put aspectj library's (1.6.13 for instance) other versions to buildpath/classpath.
By putting an assignment of list on a variable first
myVar <- list()
it opens the possibility of hiearchial assignments by
myVar[[1]] <- list()
myVar[[2]] <- list()
and so on... so now it's possible to do
myVar[[1]][[1]] <- c(...)
myVar[[1]][[2]] <- c(...)
myVar[[1]][['subVar']] <- c(...)
and so on
it is also possible to assign directly names (instead of $)
myVar[['nameofsubvar]] <- list()
and then
myVar[['nameofsubvar]][['nameofsubsubvar']] <- c('...')
important to remember is to always use double brackets to make the system work
then to get information is simple
myVar$nameofsubvar$nameofsubsubvar
and so on...
example:
a <-list()
a[['test']] <-list()
a[['test']][['subtest']] <- c(1,2,3)
a
$test
$test$subtest
[1] 1 2 3
a[['test']][['sub2test']] <- c(3,4,5)
a
$test
$test$subtest
[1] 1 2 3
$test$sub2test
[1] 3 4 5
a nice feature of the R language in it's hiearchial definition...
I used it for a complex implementation (with more than two levels) and it works!
Update:
Separate the event and property bindings:
<select [ngModel]="selectedItem" (ngModelChange)="onChange($event)">
onChange(newValue) {
console.log(newValue);
this.selectedItem = newValue; // don't forget to update the model here
// ... do other stuff here ...
}
You could also use
<select [(ngModel)]="selectedItem" (ngModelChange)="onChange($event)">
and then you wouldn't have to update the model in the event handler, but I believe this causes two events to fire, so it is probably less efficient.
Old answer, before they fixed a bug in beta.1:
Create a local template variable and attach a (change)
event:
<select [(ngModel)]="selectedItem" #item (change)="onChange(item.value)">

If you want to get the ASCII value of a character, or just convert it into an int, you need to cast from a char to an int.
What's casting? Casting is when we explicitly convert from one primitve data type, or a class, to another. Here's a brief example.
public class char_to_int
{
public static void main(String args[])
{
char myChar = 'a';
int i = (int) myChar; // cast from a char to an int
System.out.println ("ASCII value - " + i);
}
In this example, we have a character ('a'), and we cast it to an integer. Printing this integer out will give us the ASCII value of 'a'.
Since Steve Tjoa's answer always pops up first and mostly lonely when I search for multiple y-axes at Google, I decided to add a slightly modified version of his answer. This is the approach from this matplotlib example.
Reasons:

Make sure the listen_addresses
in postgresql.conf
(or ALTER SYSTEM SET
) allows incoming connections on all available IP interfaces.
listen_addresses = '*'
After the changes you have to reload the configuration. One way to do this is execute this SELECT
as a superuser.
SELECT pg_reload_conf();
Note: to change listen_addresses
, a reload is not enough, and you have to restart the server.
Ugly, (and doesn't use your method call above) but works:
echo 'First day of the month: ' . date('m/d/y h:i a',(strtotime('this month',strtotime(date('m/01/y')))));
