Let's say you have added a file "xyz.js" under assets/js folder in some Angular project in Visual-Studio, then the easiest way to include that file is to add it to .angular-cli.json
"scripts": [ "assets/js/xyz.js" ],
You should be able to use this JS file's functionality in your component or .ts files.
Only suggestion is to access your resp_dict
via .get()
for a more graceful approach that will degrade well if the data isn't as expected.
resp_dict = json.loads(resp_str)
resp_dict.get('name') # will return None if 'name' doesn't exist
You could also add some logic to test for the key if you want as well.
if 'name' in resp_dict:
resp_dict['name']
else:
# do something else here.
We recently ran into a similar issue and was unable to find anything obvious as the cause. There turned out to be a control character in our string but when we outputted that string to the browser that character was not visible unless we copied the text into an IDE.
We managed to solve our problem thanks to this post and this:
preg_replace('/[\x00-\x1F\x7F]/', '', $input);
With the help of ProgrammersBlock posts I came up with this. My needs were slightly different. I needed to take a string and return it as a LocalDate object. I was handed code that was using the older Calendar and SimpleDateFormat. I wanted to make it a little more current. This is what I came up with.
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
void ExampleFormatDate() {
LocalDate formattedDate = null; //Declare LocalDate variable to receive the formatted date.
DateTimeFormatter dateTimeFormatter; //Declare date formatter
String rawDate = "2000-01-01"; //Test string that holds a date to format and parse.
dateTimeFormatter = DateTimeFormatter.ISO_LOCAL_DATE;
//formattedDate.parse(String string) wraps the String.format(String string, DateTimeFormatter format) method.
//First, the rawDate string is formatted according to DateTimeFormatter. Second, that formatted string is parsed into
//the LocalDate formattedDate object.
formattedDate = formattedDate.parse(String.format(rawDate, dateTimeFormatter));
}
Hopefully this will help someone, if anyone sees a better way of doing this task please add your input.
Add android:windowSoftInputMode="adjustPan"
to manifest - to the corresponding activity:
<activity android:name="MyActivity"
...
android:windowSoftInputMode="adjustPan"
...
</activity>
You could use @> operator to do this something like
SELECT info->>'name'
FROM rabbits
WHERE info->'food' @> '"carrots"';
ALTER TABLE
can do multiple table alterations in one statement, but MODIFY COLUMN
can only work on one column at a time, so you need to specify MODIFY COLUMN
for each column you want to change:
ALTER TABLE webstore.Store
MODIFY COLUMN ShortName VARCHAR(100),
MODIFY COLUMN UrlShort VARCHAR(100);
Also, note this warning from the manual:
When you use CHANGE or MODIFY,
column_definition
must include the data type and all attributes that should apply to the new column, other than index attributes such as PRIMARY KEY or UNIQUE. Attributes present in the original definition but not specified for the new definition are not carried forward.
You close the second Scanner
which closes the underlying InputStream
, therefore the first Scanner
can no longer read from the same InputStream
and a NoSuchElementException
results.
The solution: For console apps, use a single Scanner
to read from System.in
.
Aside: As stated already, be aware that Scanner#nextInt
does not consume newline characters. Ensure that these are consumed before attempting to call nextLine
again by using Scanner#newLine()
.
See: Do not create multiple buffered wrappers on a single InputStream
This would work. Looping thorough array(yourArray) . Then loop through direct properties of each object (eachObj) .
yourArray.forEach( function (eachObj){
for (var key in eachObj) {
if (eachObj.hasOwnProperty(key)){
console.log(key,eachObj[key]);
}
}
});
This worked for me using python 3.
It gets a list of URLs from the csv file and starts downloading them into a folder. In case the content or image does not exist it takes that exception and continues making its magic.
import urllib.request
import csv
import os
errorCount=0
file_list = "/Users/$USER/Desktop/YOUR-FILE-TO-DOWNLOAD-IMAGES/image_{0}.jpg"
# CSV file must separate by commas
# urls.csv is set to your current working directory make sure your cd into or add the corresponding path
with open ('urls.csv') as images:
images = csv.reader(images)
img_count = 1
print("Please Wait.. it will take some time")
for image in images:
try:
urllib.request.urlretrieve(image[0],
file_list.format(img_count))
img_count += 1
except IOError:
errorCount+=1
# Stop in case you reach 100 errors downloading images
if errorCount>100:
break
else:
print ("File does not exist")
print ("Done!")

I ran into this issue as well. I don't know the technical details of what was actually happening. However, in my situation, the root cause was that there was cascading deletes setup in the Oracle database and my JPA/Hibernate code was also trying to do the cascading delete calls. So my advice is to make sure that you know exactly what is happening.
I always use parseInt, but beware of leading zeroes that will force it into octal mode.
I know this question has a good answer with 't', but thought I would add another solution.
$first = date("Y-m-d", strtotime("first day of this month"));
$last = date("Y-m-d", strtotime("last day of this month"));
In my case I used blow code for different environment.
document.cookie = name +`=; Path=/; Expires=Thu, 01 Jan 1970 00:00:01 GMT;Domain=.${document.domain.split('.').splice(1).join('.')}`;
All the answers here are totally overcomplicated, or otherwise just totally wrong.
html:
<div>
<input type="file" />
<button>Select File</button>
</div>
css:
input {
display: none;
}
javascript:
$('button').on('click', function(){
$('input').trigger('click');
});
I created this fiddle, in the most simplistic way. Clicking the Select File button will bring up the file select menu. You could then stylize the button any way you wanted. Basically, all you need to do is hide the file input, and trigger a synthetic click on it when you click another button. I spot tested this on IE 9, FF, and Chrome, and they all work fine.
Applying the Observer Pattern with delegates and events in c# is named "Event Pattern" according to MSDN which is a slight variation.
In this Article you will find well structured examples of how to apply the pattern in c# both the classic way and using delegates and events.
Exploring the Observer Design Pattern
public class Stock
{
//declare a delegate for the event
public delegate void AskPriceChangedHandler(object sender,
AskPriceChangedEventArgs e);
//declare the event using the delegate
public event AskPriceChangedHandler AskPriceChanged;
//instance variable for ask price
object _askPrice;
//property for ask price
public object AskPrice
{
set
{
//set the instance variable
_askPrice = value;
//fire the event
OnAskPriceChanged();
}
}//AskPrice property
//method to fire event delegate with proper name
protected void OnAskPriceChanged()
{
AskPriceChanged(this, new AskPriceChangedEventArgs(_askPrice));
}//AskPriceChanged
}//Stock class
//specialized event class for the askpricechanged event
public class AskPriceChangedEventArgs : EventArgs
{
//instance variable to store the ask price
private object _askPrice;
//constructor that sets askprice
public AskPriceChangedEventArgs(object askPrice) { _askPrice = askPrice; }
//public property for the ask price
public object AskPrice { get { return _askPrice; } }
}//AskPriceChangedEventArgs
You have to loop over the input array and add rules for each input as described here: Loop Over Rules
Here is a some code for ya:
$input = Request::all();
$rules = [];
foreach($input['name'] as $key => $val)
{
$rules['name.'.$key] = 'required|distinct|min:3';
}
$rules['amount'] = 'required|integer|min:1';
$rules['description'] = 'required|string';
$validator = Validator::make($input, $rules);
//Now check validation:
if ($validator->fails())
{
/* do something */
}
The triple quotes answer is great for ASCII art, but for those wondering - what if my multiple lines are a tuple, list, or other iterable that returns strings (perhaps a list comprehension?), then how about:
print("\n".join(<*iterable*>))
For example:
print("\n".join(["{}={}".format(k, v) for k, v in os.environ.items() if 'PATH' in k]))
Java supports two methods for XML parsing out of the box.
SAXParser
You can use this parser if you want to parse large XML files and/or don't want to use a lot of memory.
http://download.oracle.com/javase/6/docs/api/javax/xml/parsers/SAXParserFactory.html
Example: http://www.mkyong.com/java/how-to-read-xml-file-in-java-sax-parser/
DOMParser
You can use this parser if you need to do XPath queries or need to have the complete DOM available.
http://download.oracle.com/javase/6/docs/api/javax/xml/parsers/DocumentBuilderFactory.html
Example: http://www.mkyong.com/java/how-to-read-xml-file-in-java-dom-parser/
I once had a json that had ids that needed to be incremented by one since they were 0-indexed and that was breaking Mysql auto-increment.
So for each object I wrote this code - might be helpful to someone:
public static void incrementValue(JSONObject obj, List<String> keysToIncrementValue) {
Set<String> keys = obj.keySet();
for (String key : keys) {
Object ob = obj.get(key);
if (keysToIncrementValue.contains(key)) {
obj.put(key, (Integer)obj.get(key) + 1);
}
if (ob instanceof JSONObject) {
incrementValue((JSONObject) ob, keysToIncrementValue);
}
else if (ob instanceof JSONArray) {
JSONArray arr = (JSONArray) ob;
for (int i=0; i < arr.length(); i++) {
Object arrObj = arr.get(0);
if (arrObj instanceof JSONObject) {
incrementValue((JSONObject) arrObj, keysToIncrementValue);
}
}
}
}
}
usage:
JSONObject object = ....
incrementValue(object, Arrays.asList("id", "product_id", "category_id", "customer_id"));
this can be transformed to work for JSONArray as parent object too

I had the same issue and I needed an algorithm using a config file. In This way you can use multiple fields define by a configuration file (simulate just by a List<String) config)
public static void test() {
// Associate your configName with your Comparator
Map<String, Comparator<DocumentDto>> map = new HashMap<>();
map.put("id", new IdSort());
map.put("createUser", new DocumentUserSort());
map.put("documentType", new DocumentTypeSort());
/**
In your config.yml file, you'll have something like
sortlist:
- documentType
- createUser
- id
*/
List<String> config = new ArrayList<>();
config.add("documentType");
config.add("createUser");
config.add("id");
List<Comparator<DocumentDto>> sorts = new ArrayList<>();
for (String comparator : config) {
sorts.add(map.get(comparator));
}
// Begin creation of the list
DocumentDto d1 = new DocumentDto();
d1.setDocumentType(new DocumentTypeDto());
d1.getDocumentType().setCode("A");
d1.setId(1);
d1.setCreateUser("Djory");
DocumentDto d2 = new DocumentDto();
d2.setDocumentType(new DocumentTypeDto());
d2.getDocumentType().setCode("A");
d2.setId(2);
d2.setCreateUser("Alex");
DocumentDto d3 = new DocumentDto();
d3.setDocumentType(new DocumentTypeDto());
d3.getDocumentType().setCode("A");
d3.setId(3);
d3.setCreateUser("Djory");
DocumentDto d4 = new DocumentDto();
d4.setDocumentType(new DocumentTypeDto());
d4.getDocumentType().setCode("A");
d4.setId(4);
d4.setCreateUser("Alex");
DocumentDto d5 = new DocumentDto();
d5.setDocumentType(new DocumentTypeDto());
d5.getDocumentType().setCode("D");
d5.setId(5);
d5.setCreateUser("Djory");
DocumentDto d6 = new DocumentDto();
d6.setDocumentType(new DocumentTypeDto());
d6.getDocumentType().setCode("B");
d6.setId(6);
d6.setCreateUser("Alex");
DocumentDto d7 = new DocumentDto();
d7.setDocumentType(new DocumentTypeDto());
d7.getDocumentType().setCode("B");
d7.setId(7);
d7.setCreateUser("Alex");
List<DocumentDto> documents = new ArrayList<>();
documents.add(d1);
documents.add(d2);
documents.add(d3);
documents.add(d4);
documents.add(d5);
documents.add(d6);
documents.add(d7);
// End creation of the list
// The Sort
Stream<DocumentDto> docStream = documents.stream();
// we need to reverse this list in order to sort by documentType first because stream are pull-based, last sorted() will have the priority
Collections.reverse(sorts);
for(Comparator<DocumentDto> entitySort : sorts){
docStream = docStream.sorted(entitySort);
}
documents = docStream.collect(Collectors.toList());
// documents has been sorted has you configured
// in case of equality second sort will be used.
System.out.println(documents);
}
Comparator objects are really simple.
public class IdSort implements Comparator<DocumentDto> {
@Override
public int compare(DocumentDto o1, DocumentDto o2) {
return o1.getId().compareTo(o2.getId());
}
}
public class DocumentUserSort implements Comparator<DocumentDto> {
@Override
public int compare(DocumentDto o1, DocumentDto o2) {
return o1.getCreateUser().compareTo(o2.getCreateUser());
}
}
public class DocumentTypeSort implements Comparator<DocumentDto> {
@Override
public int compare(DocumentDto o1, DocumentDto o2) {
return o1.getDocumentType().getCode().compareTo(o2.getDocumentType().getCode());
}
}
Conclusion : this method isn't has efficient but you can create generic sort using a file configuration in this way.

Filter: - A filter as the name suggests is a Java class executed by the servlet container for each incoming HTTP request and for each http response. This way, is possible to manage HTTP incoming requests before them reach the resource, such as a JSP page, a servlet or a simple static page; in the same way is possible to manage HTTP outbound response after resource execution.
Interceptor: - Spring Interceptors are similar to Servlet Filters but they acts in Spring Context so are many powerful to manage HTTP Request and Response but they can implement more sophisticated behavior because can access to all Spring context.

To keep this question current it is worth highlighting that AssemblyInformationalVersion
is used by NuGet and reflects the package version including any pre-release suffix.
For example an AssemblyVersion of 1.0.3.* packaged with the asp.net core dotnet-cli
dotnet pack --version-suffix ci-7 src/MyProject
Produces a package with version 1.0.3-ci-7 which you can inspect with reflection using:
CustomAttributeExtensions.GetCustomAttribute<AssemblyInformationalVersionAttribute>(asm);
Its simple. You just have to set the upstream for the current branch
$ git clone repo
$ git checkout -b newbranch
$ git branch --set-upstream-to=origin/branch newbranch
$ git pull

To open new tab using JavascriptExecutor,
((JavascriptExecutor) driver).executeScript("window.open()");
ArrayList<String> tabs = new ArrayList<String>(driver.getWindowHandles());
driver.switchTo().window(tabs.get(1));
Will control on tab as according to index:
driver.switchTo().window(tabs.get(1));
Driver control on main tab:
driver.switchTo().window(tabs.get(0));
Sometimes this error also appears when you have a var or a let that hasn't been intialized.
For example
class ViewController: UIViewController {
var x: Double
// or
var y: String
// or
let z: Int
}
Depending on what your variable is supposed to do you might either set that var type as an optional or initialize it with a value like the following
class ViewController: UIViewCOntroller {
// Set an initial value for the variable
var x: Double = 0
// or an optional String
var y: String?
// or
let z: Int = 2
}
If you load you table file with dtype=str
or convert column type to string df['a'] = df['a'].astype(str)
then you can use such approach:
df['a']= 'col' + df['a'].str[:]
This approach allows prepend, append, and subset string of df
.

The short answer for old versions of Rails (see other answers for Rails 4+):
add_index :table_name, :column_name, unique: true
To index multiple columns together, you pass an array of column names instead of a single column name,
add_index :table_name, [:column_name_a, :column_name_b], unique: true
If you get "index name... is too long", you can add name: "whatever"
to the add_index method to make the name shorter.
For fine-grained control, there's a "execute
" method that executes straight SQL.
That's it!
If you are doing this as a replacement for regular old model validations, check to see how it works. The error reporting to the user will likely not be as nice without model-level validations. You can always do both.
If on your system User Control Account is Off then you can run the XAMPP as Administrator and check the boxes for run as service.
And if on your system User Control Account is On then it may not work. You have go to Configuration files and manually install as a service or run apache_installservice.bat for Apache and mysql_installservice.bat for MySQL at the path
- C:\xampp\apache
- C:\xampp\mysql
if path is the default path.

Have you considered appending to the url a meaningless query string parameter?
<iframe src="myBaseURL.com/something/" />
<script>
var i = document.getElementsById("iframe")[0],
src = i.src,
number = 1;
//For an update
i.src = src + "?ignoreMe=" + number;
number++;
</script>
It won't be seen & if you are aware of the parameter being safe then it should be fine.
Padding is essentially added to the width, therefore when you say width:100%
and padding: 5px 10px
you're actually adding 20px to the 100% width.
I think the load event is right. What is not right is the way you use to retreive the content from iframe content dom.
What you need is the html of the page loaded in the iframe not the html of the iframe object.
What you have to do is to access the content document with iFrameObj.contentDocument
.
This returns the dom of the page loaded inside the iframe, if it is on the same domain of the current page.
I would retreive the content before removing the iframe.
I've tested in firefox and opera.
Then i think you can retreive your data with $(childDom).html()
or $(childDom).find('some selector') ...
The DBA views are restricted. So you won't be able to query them unless you're connected as a DBA or similarly privileged user.
The ALL views show you the information you're allowed to see. Normally that would be jobs you've submitted, unless you have additional privileges.
The privileges you need are defined in the Admin Guide. Find out more.
So, either you need a DBA account or you need to chat with your DBA team about getting access to the information you need.

Create a migration file using cli command:
php artisan make:migration add_paid_to_users_table --table=users
A file will be created in the migrations folder, open it in an editor.
Add to the function up():
Schema::table('users', function (Blueprint $table) {
// Create new column
// You probably want to make the new column nullable
$table->integer('paid')->nullable()->after('status');
}
Add to the function down(), this will run in case migration fails for some reasons:
$table->dropColumn('paid');
Run migration using cli command:
php artisan migrate
In case you want to add a column to the table to create a foreign key constraint:
In step 3 of the above process, you'll use the following code:
$table->bigInteger('address_id')->unsigned()->nullable()->after('tel_number');
$table->foreign('address_id')->references('id')->on('addresses')->onDelete('SET NULL');
In step 4 of the above process, you'll use the following code:
// 1. Drop foreign key constraints
$table->dropForeign(['address_id']);
// 2. Drop the column
$table->dropColumn('address_id');

The short answer is for creating an attribute in c# you only need to inherit it from Attribute class, Just this :)
But here I'm going to explain attributes in detail:
basically attributes are classes that we can use them for applying our logic to assemblies, classes, methods, properties, fields, ...
In .Net, Microsoft has provided some predefined Attributes like Obsolete or Validation Attributes like ( [Required], [StringLength(100)], [Range(0, 999.99)]), also we have kind of attributes like ActionFilters in asp.net that can be very useful for applying our desired logic to our codes (read this article about action filters if you are passionate to learn it)
one another point, you can apply a kind of configuration on your attribute via AttibuteUsage.
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Struct, AllowMultiple = true)]
When you decorate an attribute class with AttributeUsage you can tell to c# compiler where I'm going to use this attribute: I'm going to use this on classes, on assemblies on properties or on ... and my attribute is allowed to use several times on defined targets(classes, assemblies, properties,...) or not?!
After this definition about attributes I'm going to show you an example: Imagine we want to define a new lesson in university and we want to allow just admins and masters in our university to define a new Lesson, Ok?

In the real world of programming maybe we don't use this approach for using attributes and I said this because of its educational point in using attributes
The working directory is a common concept across virtually all operating systems and program languages etc. It's the directory in which your program is running. This is usually (but not always, there are ways to change it) the directory the application is in.
Relative paths are ones that start without a drive specifier. So in linux they don't start with a /
, in windows they don't start with a C:\
, etc. These always start from your working directory.
Absolute paths are the ones that start with a drive (or machine for network paths) specifier. They always go from the start of that drive.
You are using setTimeout
wrong way. The (one of) function signature is setTimeout(callback, delay)
. So you can easily specify what code should be run after what delay.
var codeAddress = (function() {
var index = 0;
var delay = 100;
function GeocodeCallback(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
new google.maps.Marker({ map: map, position: results[0].geometry.location, animation: google.maps.Animation.DROP });
console.log(results);
}
else alert("Geocode was not successful for the following reason: " + status);
};
return function(vPostCode) {
if (geocoder) setTimeout(geocoder.geocode.bind(geocoder, { 'address': "'" + vPostCode + "'"}, GeocodeCallback), index*delay);
index++;
};
})();
This way, every codeAddress()
call will result in geocoder.geocode()
being called 100ms later after previous call.
I also added animation to marker so you will have a nice animation effect with markers being added to map one after another. I'm not sure what is the current google limit, so you may need to increase the value of delay
variable.
Also, if you are each time geocoding the same addresses, you should instead save the results of geocode to your db and next time just use those (so you will save some traffic and your application will be a little bit quicker)
run command prompt as administrator and use '--user' flag eg. pip install --user --upgrade pandas
You can use this solution for removing a char:

Application.Current.DispatcherUnhandledException will not catch exceptions that are thrown from another thread then the main thread.
That actual depend on how the thread was created
One case that is not handled by Application.Current.DispatcherUnhandledException is System.Windows.Forms.Timer for which Application.ThreadException can be used to handle these if you run Forms on other threads than the main thread you will need to set Application.ThreadException from each such thread
I previously came up with a different workaround that doesn't use stored procedures, but instead uses a parameter table and some connection_id() magic.
EDIT (Copied up from comments)
create a table that contains a column called connection_id
(make it a bigint). Place columns in that table for parameters for the view. Put a primary key on the connection_id
. replace into the parameter table and use CONNECTION_ID()
to populate the connection_id value. In the view use a cross join to the parameter table and put WHERE param_table.connection_id = CONNECTION_ID()
. This will cross join with only one row from the parameter table which is what you want. You can then use the other columns in the where clause for example where orders.order_id = param_table.order_id
.
Use :
FileInfo fInfo = new FileInfo('FilePath');
var fFirstTime = fInfo.CreationTime;
var fLastTime = fInfo.LastWriteTime;
public void SomeMethod(List<DateTime> dates)
{
// do something
}
For Git Bash for Windows (in ConEmu), the following works for me (for Docker Windows containers):
docker run --rm -it -v `pwd -W`:c:/api microsoft/dotnet:2-runtime
Note the backticks/backquotes around pwd -W
!
With all other variations of PWD I've tried I've received: "Error response from daemon: invalid volume specification: ..."
Update: The above was for Docker Windows containers, for Linux containers use:
docker run --rm -it -v `pwd -W`:/api -p 8080:80 microsoft/aspnetcore:2

All the other solutions are creepy because they are from someone that arrogantly simply thinks that English is the only language in the world :)
All those solutions strip also diacritics like ç or à.
The perfect solution, as stated in PHP documentation, is simply:
$clear = strip_tags($des);
What is your output when you do java -version
? This will tell you what version the running JVM is.
The Unsupported major.minor version 51.0 error could mean:
Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor
error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)
See: http://www.java.com/en/download/manual.jsp (7 Update 25 )
and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)
for the latest version of the JRE and JDK respectively.
EDIT:
Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.
Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.

Next time, use a single "alter table" statement to update the primary key.
alter table xx drop primary key, add primary key(k1, k2, k3);
To fix things:
create table fixit (user_2, user_1, type, timestamp, n, primary key( user_2, user_1, type) );
lock table fixit write, user_interactions u write, user_interactions write;
insert into fixit
select user_2, user_1, type, max(timestamp), count(*) n from user_interactions u
group by user_2, user_1, type
having n > 1;
delete u from user_interactions u, fixit
where fixit.user_2 = u.user_2
and fixit.user_1 = u.user_1
and fixit.type = u.type
and fixit.timestamp != u.timestamp;
alter table user_interactions add primary key (user_2, user_1, type );
unlock tables;
The lock should stop further updates coming in while your are doing this. How long this takes obviously depends on the size of your table.
The main problem is if you have some duplicates with the same timestamp.
You may find an answer with this example : errorbar_demo_features.py
"""
Demo of errorbar function with different ways of specifying error bars.
Errors can be specified as a constant value (as shown in `errorbar_demo.py`),
or as demonstrated in this example, they can be specified by an N x 1 or 2 x N,
where N is the number of data points.
N x 1:
Error varies for each point, but the error values are symmetric (i.e. the
lower and upper values are equal).
2 x N:
Error varies for each point, and the lower and upper limits (in that order)
are different (asymmetric case)
In addition, this example demonstrates how to use log scale with errorbar.
"""
import numpy as np
import matplotlib.pyplot as plt
# example data
x = np.arange(0.1, 4, 0.5)
y = np.exp(-x)
# example error bar values that vary with x-position
error = 0.1 + 0.2 * x
# error bar values w/ different -/+ errors
lower_error = 0.4 * error
upper_error = error
asymmetric_error = [lower_error, upper_error]
fig, (ax0, ax1) = plt.subplots(nrows=2, sharex=True)
ax0.errorbar(x, y, yerr=error, fmt='-o')

I have wasted 3 days
ultimately solved a graph question
used for
finding shortest distance
using BFS
Want to share the experience.
When the (undirected for me) graph has
fixed distance (1, 6, etc.) for edges
#1
We can use BFS to find shortest path simply by traversing it
then, if required, multiply with fixed distance (1, 6, etc.)
#2
As noted above
with BFS
the very 1st time an adjacent node is reached, it is shortest path
#3
It does not matter what queue you use
deque/queue(c++) or
your own queue implementation (in c language)
A circular queue is unnecessary
#4
Number of elements required for queue is N+1 at most, which I used
(dint check if N works)
here, N is V, number of vertices.
#5
Wikipedia BFS will work, and is sufficient.
https://en.wikipedia.org/wiki/Breadth-first_search#Pseudocode
I have lost 3 days trying all above alternatives, verifying & re-verifying again and again above
they are not the issue.
(Try to spend time looking for other issues, if you dint find any issues with above 5).
More explanation from the comment below:
A
/ \
B C
/\ /\
D E F G
Assume above is your graph
graph goes downwards
For A, the adjacents are B & C
For B, the adjacents are D & E
For C, the adjacents are F & G
say, start node is A
when you reach A, to, B & C the shortest distance to B & C from A is 1
when you reach D or E, thru B, the shortest distance to A & D is 2 (A->B->D)
similarly, A->E is 2 (A->B->E)
also, A->F & A->G is 2
So, now instead of 1 distance between nodes, if it is 6, then just multiply the answer by 6
example,
if distance between each is 1, then A->E is 2 (A->B->E = 1+1)
if distance between each is 6, then A->E is 12 (A->B->E = 6+6)
yes, bfs may take any path
but we are calculating for all paths
if you have to go from A to Z, then we travel all paths from A to an intermediate I, and since there will be many paths we discard all but shortest path till I, then continue with shortest path ahead to next node J
again if there are multiple paths from I to J, we only take shortest one
example,
assume,
A -> I we have distance 5
(STEP) assume, I -> J we have multiple paths, of distances 7 & 8, since 7 is shortest
we take A -> J as 5 (A->I shortest) + 8 (shortest now) = 13
so A->J is now 13
we repeat now above (STEP) for J -> K and so on, till we get to Z
Read this part, 2 or 3 times, and draw on paper, you will surely get what i am saying, best of luck

Yes, you can configure the Spring servlet context xml file to define your beans (i.e., classes), so that it can do the automatic injection for you. However, do note, that you have to do other configurations to have Spring up and running and the best way to do that, is to follow a tutorial ground up.
Once you have your Spring configured probably, you can do the following in your Spring servlet context xml file for Example 1 above to work (please replace the package name of com.movies to what the true package name is and if this is a 3rd party class, then be sure that the appropriate jar file is on the classpath) :
<beans:bean id="movieFinder" class="com.movies.MovieFinder" />
or if the MovieFinder class has a constructor with a primitive value, then you could something like this,
<beans:bean id="movieFinder" class="com.movies.MovieFinder" >
<beans:constructor-arg value="100" />
</beans:bean>
or if the MovieFinder class has a constructor expecting another class, then you could do something like this,
<beans:bean id="movieFinder" class="com.movies.MovieFinder" >
<beans:constructor-arg ref="otherBeanRef" />
</beans:bean>
...where 'otherBeanRef' is another bean that has a reference to the expected class.

I'm using IBM Data Studio v 3.1.1.0 with an underlying DB2 for z/OS and the accepted answer didn't work for me. If you're using IBM Data Studio (v3.1.1.0) you can:
There is no special git ignore
command.
Edit a .gitignore
file located in the appropriate place within the working copy. You should then add this .gitignore
and commit it. Everyone who clones that repo will than have those files ignored.
Note that only file names starting with /
will be relative to the directory .gitignore
resides in. Everything else will match files in whatever subdirectory.
You can also edit .git/info/exclude
to ignore specific files just in that one working copy. The .git/info/exclude
file will not be committed, and will thus only apply locally in this one working copy.
You can also set up a global file with patterns to ignore with git config --global core.excludesfile
. This will locally apply to all git working copies on the same user's account.
Run git help gitignore
and read the text for the details.
There is no ANSI C function that provides better than 1 second time resolution but the POSIX function gettimeofday
provides microsecond resolution. The clock function only measures the amount of time that a process has spent executing and is not accurate on many systems.
You can use this function like this:
struct timeval tval_before, tval_after, tval_result;
gettimeofday(&tval_before, NULL);
// Some code you want to time, for example:
sleep(1);
gettimeofday(&tval_after, NULL);
timersub(&tval_after, &tval_before, &tval_result);
printf("Time elapsed: %ld.%06ld\n", (long int)tval_result.tv_sec, (long int)tval_result.tv_usec);
This returns Time elapsed: 1.000870
on my machine.
2 steps to check if a cronjob is working :
Manually run php command :

And check if any error is displayed
The first is a much better option.
Parallel.ForEach, internally, uses a Partitioner<T>
to distribute your collection into work items. It will not do one task per item, but rather batch this to lower the overhead involved.
The second option will schedule a single Task
per item in your collection. While the results will be (nearly) the same, this will introduce far more overhead than necessary, especially for large collections, and cause the overall runtimes to be slower.
FYI - The Partitioner used can be controlled by using the appropriate overloads to Parallel.ForEach, if so desired. For details, see Custom Partitioners on MSDN.
The main difference, at runtime, is the second will act asynchronous. This can be duplicated using Parallel.ForEach by doing:
Task.Factory.StartNew( () => Parallel.ForEach<Item>(items, item => DoSomething(item)));
By doing this, you still take advantage of the partitioners, but don't block until the operation is complete.
A gotcha I ran into: The following two commands are equivalent. Note the first cannot use quotes. Somewhat counterintuitively, quoting the string when using %env VAR ...
will result in the quotes being included as part of the variable's value, which is probably not what you want.

Stopwatch is designed for this purpose and is one of the best way to measure execution time in .NET.
var watch = System.Diagnostics.Stopwatch.StartNew();
/* the code that you want to measure comes here */
watch.Stop();
var elapsedMs = watch.ElapsedMilliseconds;
Do not use DateTimes to measure execution time in .NET.
It is a missing dll. Possibly, your dll that works with com ports have an unresolved dll dependence. You can use dependency walker and windows debugger. Check all of the mfc library, for example. Also, you can use nrCommlib - it is great components to work with com ports.

Now, to your question:
how to compare two elements coming from xml as string
In Xpath 1.0 strings can be compared only for equality (or inequality), using the operator =
and the function not()
together with the operator =
.
$str1 = $str2
evaluates to true()
exactly when the string $str1
is equal to the string $str2
.
not($str1 = $str2)
evaluates to true()
exactly when the string $str1
is not equal to the string $str2
.
There is also the !=
operator. It generally should be avoided because it has anomalous behavior whenever one of its operands is a node-set.
Now, the rules for comparing two element nodes are similar:
$el1 = $el2
evaluates to true()
exactly when the string value of $el1
is equal to the string value of $el2
.
not($el1 = $el2)
evaluates to true()
exactly when the string value of $el1
is not equal to the string value of $el2
.
However, if one of the operands of =
is a node-set, then
$ns = $str
evaluates to true()
exactly when there is at least one node in the node-set $ns1
, whose string value is equal to the string $str
$ns1 = $ns2
evaluates to true()
exactly when there is at least one node in the node-set $ns1
, whose string value is equal to the string value of some node from $ns2
Therefore, the expression:
OU_NAME='OU_ADDR1'
evaluates to true()
only when there is at least one element child of the current node that is named OU_NAME
and whose string value is the string 'OU_ADDR1'.
This is obviously not what you want!
Most probably you want:
OU_NAME=OU_ADDR1
This expression evaluates to true
exactly there is at least one OU_NAME
child of the current node and one OU_ADDR1
child of the current node with the same string value.
Finally, in XPath 2.0, strings can be compared also using the value comparison operators lt
, le
, eq
, gt
, ge
and the inherited from XPath 1.0 general comparison operator =
.
Trying to evaluate a value comparison operator when one or both of its arguments is a sequence of more than one item results in error.
Parameters are key-value pairs that can appear inside URL path, and start with a semicolon character (;
).
Query string appears after the path (if any) and starts with a question mark character (?
).
Both parameters and query string contain key-value pairs.
In a GET
request, parameters appear in the URL itself:
<scheme>://<username>:<password>@<host>:<port>/<path>;<parameters>?<query>#<fragment>
In a POST
request, parameters can appear in the URL itself, but also in the datastream (as known as content).
Query string is always a part of the URL.
Parameters can be buried in form-data
datastream when using POST method so they may not appear in the URL. Yes a POST
request can define parameters as form data and in the URL, and this is not inconsistent because parameters can have several values.
I've found no explaination for this behavior so far. I guess it might be useful sometimes to "unhide" parameters from a POST
request, or even let the code handling a GET
request share some parts with the code handling a POST
. Of course this can work only with server code supporting parameters in a URL.
Until you get better insights, I suggest you to use parameters only in form-data
datastream of POST
requests.

For swift 3, I couldn't use just reachability from RAJAMOHAN-S solutions since it returns "true" if there is WiFi but no Internet. Thus, I implemented second validation via URLSession class and completion handler.
Here is the whole class.
import Foundation
import SystemConfiguration
public class Reachability {
class func isConnectedToNetwork() -> Bool {
var zeroAddress = sockaddr_in(sin_len: 0, sin_family: 0, sin_port: 0, sin_addr: in_addr(s_addr: 0), sin_zero: (0, 0, 0, 0, 0, 0, 0, 0))
zeroAddress.sin_len = UInt8(MemoryLayout.size(ofValue: zeroAddress))
zeroAddress.sin_family = sa_family_t(AF_INET)
let defaultRouteReachability = withUnsafePointer(to: &zeroAddress) {
$0.withMemoryRebound(to: sockaddr.self, capacity: 1) {zeroSockAddress in
SCNetworkReachabilityCreateWithAddress(nil, zeroSockAddress)
}
}
var flags: SCNetworkReachabilityFlags = SCNetworkReachabilityFlags(rawValue: 0)
if SCNetworkReachabilityGetFlags(defaultRouteReachability!, &flags) == false {
return false
}
// Working for Cellular and WIFI
let isReachable = (flags.rawValue & UInt32(kSCNetworkFlagsReachable)) != 0
let needsConnection = (flags.rawValue & UInt32(kSCNetworkFlagsConnectionRequired)) != 0
let ret = (isReachable && !needsConnection)
return ret
}

guard isConnectedToNetwork() else {
completionHandler(false)
return
}
// 2. Check the Internet Connection
var webAddress = "https://www.google.com" // Default Web Site
if let _ = webSiteToPing {
webAddress = webSiteToPing!
}
guard let url = URL(string: webAddress) else {
completionHandler(false)
print("could not create url from: \(webAddress)")
return
}
let urlRequest = URLRequest(url: url)
let session = URLSession.shared
let task = session.dataTask(with: urlRequest, completionHandler: { (data, response, error) in
if error != nil || response == nil {
completionHandler(false)
} else {
completionHandler(true)
}
})
task.resume()
}
}
And you call this like this, for example:
Reachability.isInternetAvailable(webSiteToPing: nil) { (isInternetAvailable) in
guard isInternetAvailable else {
// Inform user for example
return
}
// Do some action if there is Internet
}
In my case, I wanted to check out
a new branch
that has cut recently
but it's it big in size and I want to save time and internet bandwidth, as I'm in a slow metered network
so I copped the previous branch
that I already checked in
I went to the working directory, and from svn info, I can see it's on the previous branch I did the following command (you can find this command from svn switch --help
)
svn switch ^/branches/newBranchName
go check svn info
again you can see it is becoming the newBranchName go ahead and svn up
and this how I got the new branch easily, quickly with minimum data transmitting over the internet
hope sharing my case helps and speeds up your work
Join on one-to-many relation in JPQL looks as follows:
select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName
When several properties are specified in select
clause, result is returned as Object[]
:
Object[] temp = (Object[]) em.createNamedQuery("...")
.setParameter("groupName", groupName)
.getSingleResult();
String fname = (String) temp[0];
String lname = (String) temp[1];
By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table
to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:
@Entity @Table(name = "Users")
public class User implements Serializable { ... }
If you are using Sql Server Management Studio, you can create your own schema by browsing to Databases - Your Database - Security - Schemas.
To create one using a script is as easy as (for example):
CREATE SCHEMA [EnterSchemaNameHere] AUTHORIZATION [dbo]
You can use them to logically group your tables, for example by creating a schema for "Financial" information and another for "Personal" data. Your tables would then display as:
Financial.BankAccounts Financial.Transactions Personal.Address
Rather than using the default schema of dbo.
There is no built-in formula in excel, you have to add a vb script and permanently save it with your MS. Excel's installation as Add-In.

After this, From File Menu select Save Book ,from next menu select "Excel 97-2003 Add-In (*.xla)
It will save as Excel Add-In. that will be available till the Ms.Office Installation to that machine.
Now Open any Excel File in any Cell type =WordNum(<your numeric value or cell reference>)
you will see a Words equivalent of the numeric value.

If your merge was not too complicated another option would be to:
After that you are left with only the changes from the stash you dropped too early.
You can achive this with Regex and Replace or with just trimming.
Regex example:
if ($('input').val().replace(/[\s]/, '') == '') {
alert('Input is not filled!');
}
With this replace()
function you replace white spaces with nothing (removing white spaces).
Trimming Example:
if ($('input').val().trim() == '') {
alert('Input is not filled!');
}
trim()
function removes the leading and trailing white space and line terminator characters from a string.
You can also get the value of an item in the jObject like this:
JToken value;
if (json.TryGetValue(key, out value))
{
DoSomething(value);
}
Decode them and compare them as mgilson comment.
Order does not matter for dictionary as long as the keys, and values matches. (Dictionary has no order in Python)
>>> {'a': 1, 'b': 2} == {'b': 2, 'a': 1}
True
But order is important in list; sorting will solve the problem for the lists.
>>> [1, 2] == [2, 1]
False
>>> [1, 2] == sorted([2, 1])
True
>>> a = '{"errors": [{"error": "invalid", "field": "email"}, {"error": "required", "field": "name"}], "success": false}'
>>> b = '{"errors": [{"error": "required", "field": "name"}, {"error": "invalid", "field": "email"}], "success": false}'
>>> a, b = json.loads(a), json.loads(b)
>>> a['errors'].sort()
>>> b['errors'].sort()
>>> a == b
True
Above example will work for the JSON in the question. For general solution, see Zero Piraeus's answer.
You can pass it like this
let param: any = {'userId': 2};
this.http.get(`${ApiUrl}`, {params: param})
Note: I don't know the correct answer, but the below is just my personal speculation!
As has been mentioned a 0 before a number means it's octal:
04524 // octal, leading 0
Imagine needing to come up with a system to denote hexadecimal numbers, and note we're working in a C style environment. How about ending with h like assembly? Unfortunately you can't - it would allow you to make tokens which are valid identifiers (eg. you could name a variable the same thing) which would make for some nasty ambiguities.
8000h // hex
FF00h // oops - valid identifier! Hex or a variable or type named FF00h?
You can't lead with a character for the same reason:
xFF00 // also valid identifier
Using a hash was probably thrown out because it conflicts with the preprocessor:
#define ...
#FF00 // invalid preprocessor token?
In the end, for whatever reason, they decided to put an x after a leading 0 to denote hexadecimal. It is unambiguous since it still starts with a number character so can't be a valid identifier, and is probably based off the octal convention of a leading 0.
0xFF00 // definitely not an identifier!
Use the Timer
class.
public static void Main()
{
System.Timers.Timer aTimer = new System.Timers.Timer();
aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
aTimer.Interval = 5000;
aTimer.Enabled = true;
Console.WriteLine("Press \'q\' to quit the sample.");
while(Console.Read() != 'q');
}
// Specify what you want to happen when the Elapsed event is raised.
private static void OnTimedEvent(object source, ElapsedEventArgs e)
{
Console.WriteLine("Hello World!");
}
The Elapsed
event will be raised every X amount of milliseconds, specified by the Interval
property on the Timer object. It will call the Event Handler
method you specify. In the example above, it is OnTimedEvent
.
Note that find . -type f | xargs grep whatever
sorts of solutions will run into "Argument list to long" errors when there are too many files matched by find.
The best bet is grep -r
but if that isn't available, use find . -type f -exec grep -H whatever {} \;
instead.
You can't do that using open. use codecs.
when you are opening a file in python using the open built-in function you will always read/write the file in ascii. To write it in utf-8 try this:
import codecs
file = codecs.open('data.txt','w','utf-8')
Try Secure Cookie protocol described in this paper by Liu, Kovacs, Huang, and Gouda:
As stated in document:
A secure cookie protocol that runs between a client and a server needs to provide the following four services: authentication, confidentiality, integrity and anti-replay.
As for ease of deployment:
In terms of efficiency, our protocol does not involve any database lookup or public key cryptography. In terms of deployability, our protocol can be easily deployed on an existing web server, and it does not require any change to the Internet cookie specication.
In short: it is secure, lightweight, works for me just great.
This answer is to give a better understanding of this warning
Deprecation warning is caused when you use moment to create time object, var today = moment();
.
If this warning is okay with you then I have a simpler method.
Don't use date
object from js
use moment
instead. For example use moment()
to get the current date.
Or convert the js
date object to moment
date. You can simply do that specifying the format of your js
date object.
ie, moment("js date", "js date format");
eg:
moment("2014 04 25", "YYYY MM DD");
(BUT YOU CAN ONLY USE THIS METHOD UNTIL IT'S DEPRECIATED, this may be depreciated from moment
in the future)

U can use above code
With @Kevin van Mierlo 's answer, you are also capable of implementing several drawers. For instance, the default menu located on the left side (start), and a further optional menu, located on the right side, which is only shown when determinate fragments are loaded.
I've been able to do that.
To make your formula more readable, you could assign a Name to cell A0, and then use that name in the formula.
The easiest way to define a Name is to highlight the cell or range, then click on the Name box in the formula bar.
Then, if you named A0 "Rate" you can use that name like this:
=(B0+4)/(Rate)
See, much easier to read.
If you want to find Rate, click F5 and it appears in the GoTo list.
Easiest way to use this function is to start by 'Recording a Macro'. Once you start recording, save the file to the location you want, with the name you want, and then of course set the file type, most likely 'Excel Macro Enabled Workbook' ~ 'XLSM'
Stop recording and you can start inspecting your code.
I wrote the code below which allows you to save a workbook using the path where the file was originally located, naming it as "Event [date in cell "A1"]"
Option Explicit
Sub SaveFile()
Dim fdate As Date
Dim fname As String
Dim path As String
fdate = Range("A1").Value
path = Application.ActiveWorkbook.path
If fdate > 0 Then
fname = "Event " & fdate
Application.ActiveWorkbook.SaveAs Filename:=path & "\" & fname, _
FileFormat:=xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False
Else
MsgBox "Chose a date for the event", vbOKOnly
End If
End Sub
Copy the code into a new module and then write a date in cell "A1" e.g. 01-01-2016 -> assign the sub to a button and run. [Note] you need to make a save file before this script will work, because a new workbook is saved to the default autosave location!
it works for me
@JsonIgnoreProperties({"hibernateLazyInitializer","handler"})
e.g.
@Entity
@Table(name = "user")
@Data
@NoArgsConstructor
@JsonIgnoreProperties({"hibernateLazyInitializer","handler"})
public class User {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
private Date created;
}
If you are being stuck on this problem. After switch the computer and not able to upload your build to App Store. Simply click manage certificate on the error page, the + plus on the bottom left corner and create a new distribution certificate. Then you'll be good to go.
What works for me on /FF and /Chrome:
body {
position: fixed;
width: 100%;
height: 100%;
}
overflow: hidden
just disables display of the scrollbars. (But you can put it in there if you like to).
There is one drawback I found: If you use this method on a page which you want only temporarily to stop scrolling, setting position: fixed
will scroll it to the top.
This is because position: fixed uses absolute positions which are currently set to 0/0.
This can be repaired e.g. with jQuery:
var lastTop;
function stopScrolling() {
lastTop = $(window).scrollTop();
$('body').addClass( 'noscroll' )
.css( { top: -lastTop } )
;
}
function continueScrolling() {
$('body').removeClass( 'noscroll' );
$(window).scrollTop( lastTop );
}
The above answers are right, but you have to make sure you input right URL.
You have to go to: https://developers.facebook.com/apps
You have two choices to enter: http://www.example.com or http://example.com
Your app will work only with one of them. In order to make sure your visitors will use your desired url, use .htaccess on your domain.
Here's good tutorial on that: http://eppand.com/redirect-www-to-non-www-with-htaccess-file/
Enjoy!
As posted in my earlier answer
Use below code :
TelephonyManager tMgr = (TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE);
String mPhoneNumber = tMgr.getLine1Number();
In AndroidManifest.xml, give the following permission:
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
But remember, this code does not always work, since Cell phone number is dependent on the SIM Card and the Network operator / Cell phone carrier.
Also, try checking in Phone--> Settings --> About --> Phone Identity, If you are able to view the Number there, the probability of getting the phone number from above code is higher. If you are not able to view the phone number in the settings, then you won't be able to get via this code!
Suggested Workaround:
Do the above 4 steps as one time activity during the app's first launch. Later on, whenever phone number is required, use the value available in shared preference.
By default Windows defines the following prefix that is available to everyone: http://+:80/Temporary_Listen_Addresses/
So you can register your HttpListener
via:
Prefixes.Add("http://+:80/Temporary_Listen_Addresses/" + Guid.NewGuid().ToString("D") + "/";
This sometimes causes problems with software such as Skype which will try to utilise port 80 by default.
Try this.This one is written in typescript.
export function safeJsonParse(str: string) {
try {
return JSON.parse(str);
} catch (e) {
return str;
}
}
I think you had the correct idea with your last example. You only got an error because you were trying to put quotes inside an already quoted string. This will fix it:
gci -path hklm:\software\microsoft\windows\currentversion\uninstall | ForEach-Object -Process { write-output ($_.GetValue("DisplayName") + "`n") }
Edit: Keith's $() operator actually creates a better syntax (I always forget about this one). You can also escape quotes inside quotes as so:
gci -path hklm:\software\microsoft\windows\currentversion\uninstall | ForEach-Object -Process { write-output "$($_.GetValue(`"DisplayName`"))`n" }
update: please check the answer of Jeff Gilliland below for updated solution
Seems like as this thread says a breaking change was issued:
Components can no longer be imported through "@angular/material". Use the individual secondary entry-points, such as @angular/material/button.
Update: can confirm, this was the issue. After downgrading @angular/[email protected]...
to @angular/[email protected]
we could solve this temporarily. Guess we need to update the project for a long term solution.

The git blame
command is used to examine the contents of a file line by line and see when each line was last modified and who the author of the modifications was.
If there was a bug in code,use it to identify who cased it,then you can blame him. Git blame is get blame(d).
If you need to know history of one line code,use git log -S"code here"
, simpler than git blame.

I had this error when opening a CSV file and one of the fields had commas embedded in it. The field had quotes around it, and I had cut and paste the read.table with quote="" in it. Once I took quote="" out, the default behavior of read.table took over and killed the problem. So I went from this:
systems <- read.table("http://getfile.pl?test.csv", header=TRUE, sep=",", quote="")
to this:
systems <- read.table("http://getfile.pl?test.csv", header=TRUE, sep=",")
From the MongoDB cookbook page comments:

"$gte" : ISODate("2014-07-02T00:00:00Z"),
"$lt" : ISODate("2014-07-03T00:00:00Z")
}
This worked for me. In full context, the following command gets every record where the dt
date field has a date on 2013-10-01 (YYYY-MM-DD) Zulu:
db.mycollection.find({ "dt" : { "$gte" : ISODate("2013-10-01T00:00:00Z"), "$lt" : ISODate("2013-10-02T00:00:00Z") }})
Enter the following command to check if a private key and public key are a matched set (identical) or not a matched set (differ) in $USER/.ssh directory. The cut command prevents the comment at the end of the line in the public key from being compared, allowing only the key to be compared.
ssh-keygen -y -f ~/.ssh/id_rsa | diff -s - <(cut -d ' ' -f 1,2 ~/.ssh/id_rsa.pub)
Output will look like either one of these lines.
Files - and /dev/fd/63 are identical

You can get it using the :selected
selector, like this:
$("#my_select").change(function() {
var id = $(this).children(":selected").attr("id");
});
As others have said, the style you're after is actually just the Mac OS checkbox style, so it will look radically different on other devices.
In fact both screenshots you linked show what checkboxes look like on Mac OS in Chrome, the grey one is shown at non-100% zoom levels.
The simplest solution worked for me: Shutdown and restart my phone and Eclipse alike.
Ended up using .closest() instead.

Have you looked into the ViewFlipper component? Maybe it can help you.
http://developer.android.com/reference/android/widget/ViewFlipper.html
With this component, you can attach two or more view childs. If you add some translate animation and capture Gesture detection, you can have a nicely horizontal scroll.
Have a look at ?options
and use warn
:
options( warn = -1 )
You can use partial value of an attribute to detect a DOM element using (^) sign. For example you have divs like this:
<div id="abc_1"></div>
<div id="abc_2"></div>
<div id="xyz_3"></div>
<div id="xyz_4"></div>...
You can use the code:
var abc = $('div[id^=abc]')
This will return a DOM array of divs which have id starting with abc
:
<div id="abc_1"></div>
<div id="abc_2"></div>
Here is the demo: http://jsfiddle.net/mCuWS/
I had the same problem but found that it was because the password for my Service Account for the Database Engine had expired. The solution was to login to that account, fix this, then set the account so password never expires.
You can also hide spinner with following trick :
input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
opacity:0;
pointer-events:none;
}
Assuming you cannot modify DDL (to create a unique constraint) or are limited to only being able to write DML then check for a null on filtered result of your values against the whole table

Using the Functional Java library, import these:
import static fj.pre.Monoid.stringMonoid;
import static fj.data.List.list;
import fj.data.List;
... then you can do this:
List<String> ss = list("foo", "bar", "baz");
String s = stringMonoid.join(ss, ", ");
Or, the generic way, if you don't have a list of Strings:
public static <A> String showList(List<A> l, Show<A> s) {
return stringMonoid.join(l.map(s.showS_()), ", ");
}
MySQL Manual - slow-query-log-file
This claims that you can run the following to set the slow-log file (5.1.6 onwards):
set global slow_query_log_file = 'path';
The variable slow_query_log just controls whether it is enabled or not.
I was just wrestling with a similar problem myself, but didn't want the overhead of a function. I came up with the following query:
SELECT myfield::integer FROM mytable WHERE myfield ~ E'^\\d+$';
Postgres shortcuts its conditionals, so you shouldn't get any non-integers hitting your ::integer cast. It also handles NULL values (they won't match the regexp).
If you want zeros instead of not selecting, then a CASE statement should work:
SELECT CASE WHEN myfield~E'^\\d+$' THEN myfield::integer ELSE 0 END FROM mytable;
If you want to import all Material modules, create your own module i.e. material.module.ts
and do something like the following:
import { NgModule } from '@angular/core';_x000D_
import * as MATERIAL_MODULES from '@angular/material';_x000D_
_x000D_
export function mapMaterialModules() {_x000D_
return Object.keys(MATERIAL_MODULES).filter((k) => {_x000D_
let asset = MATERIAL_MODULES[k];_x000D_
return typeof asset == 'function'_x000D_
&& asset.name.startsWith('Mat')_x000D_
&& asset.name.includes('Module');_x000D_
}).map((k) => MATERIAL_MODULES[k]);_x000D_
}_x000D_
const modules = mapMaterialModules();_x000D_
_x000D_
@NgModule({_x000D_
imports: modules,_x000D_
exports: modules_x000D_
})_x000D_
export class MaterialModule { }
_x000D_
Then import the module into your app.module.ts

To prevent duplication in memory, resharper is suggesting this:
List<string> myList = new List<string>();
IEnumerable<string> myEnumerable = myList;
List<string> listAgain = myList as List<string>() ?? myEnumerable.ToList();
.ToList() returns a new immutable list. So changes to listAgain does not effect myList in @Tamas Czinege answer. This is correct in most instances for least two reasons: This helps prevent changes in one area effecting the other area (loose coupling), and it is very readable, since we shouldn't be designing code with compiler concerns.
But there are certain instances, like being in a tight loop or working on an embedded or low memory system, where compiler considerations should be taken into consideration.
This did the trick for me:
var express = require('express'),
app = express();
app.use('/', express.static(__dirname + '/'));

from FragmentActivity
. In fact, FragmentActivity
has more functionality.
Using FragmentActivity
you can easily build tab and swap
format. For each tab you can use different Fragment
(Fragments
are reusable). So for any FragmentActivity
you can reuse the same Fragment
.
Still you can use Activity
for single pages like list down something and edit element of the list in next page.
Also remember to use Activity
if you are using android.app.Fragment
; use FragmentActivity
if you are using android.support.v4.app.Fragment
. Never attach a android.support.v4.app.Fragment
to an android.app.Activity
, as this will cause an exception to be thrown.
For python 3.7:
Change directory, if you didn't add the following as your PATH: cd C:\Users{user_name}\AppData\Local\Programs\Python\Python37-32\Scripts To know where your package/application has been installed/located, type: "where program_name" like> where jupyter If you didn't find a location, you need to add the location in PATH.
Type: pip-autoremove jupyter It will ask to type y/n to confirm the action.
You can use the following flags --single-branch
&& --depth
to download the specific branch and to limit the amount of history which will be downloaded.
You will clone the repo from a certain point in time and only for the given branch
git clone -b <branch> --single-branch <url> --depth <number of commits>
--[no-]single-branch
Clone only the history leading to the tip of a single branch, either specified by the
--branch
option or the primary branch remote’sHEAD
points at.Further fetches into the resulting repository will only update the
remote-tracking
branch for the branch this option was used for the initial cloning. If the HEAD at the remote did not point at any branch when--single-branch
clone was made, no remote-tracking branch is created.
--depth
Create a shallow clone with a history truncated to the specified number of commits
This particular error implies that one of the variables being used in the arithmetic on the line has a shape incompatible with another on the same line (i.e., both different and non-scalar). Since n
and the output of np.add.reduce()
are both scalars, this implies that the problem lies with xm
and ym
, the two of which are simply your x
and y
inputs minus their respective means.
Based on this, my guess is that your x
and y
inputs have different shapes from one another, making them incompatible for element-wise multiplication.
** Technically, it's not that variables on the same line have incompatible shapes. The only problem is when two variables being added, multiplied, etc., have incompatible shapes, whether the variables are temporary (e.g., function output) or not. Two variables with different shapes on the same line are fine as long as something else corrects the issue before the mathematical expression is evaluated.
So, what happens when a server listen for incoming connections on a TCP port? For example, let's say you have a web-server on port 80. Let's assume that your computer has the public IP address of 24.14.181.229 and the person that tries to connect to you has IP address 10.1.2.3. This person can connect to you by opening a TCP socket to 24.14.181.229:80. Simple enough.
Intuitively (and wrongly), most people assume that it looks something like this:
Local Computer | Remote Computer
--------------------------------
<local_ip>:80 | <foreign_ip>:80
^^ not actually what happens, but this is the conceptual model a lot of people have in mind.
This is intuitive, because from the standpoint of the client, he has an IP address, and connects to a server at IP:PORT. Since the client connects to port 80, then his port must be 80 too? This is a sensible thing to think, but actually not what happens. If that were to be correct, we could only serve one user per foreign IP address. Once a remote computer connects, then he would hog the port 80 to port 80 connection, and no one else could connect.
Three things must be understood:
1.) On a server, a process is listening on a port. Once it gets a connection, it hands it off to another thread. The communication never hogs the listening port.
2.) Connections are uniquely identified by the OS by the following 5-tuple: (local-IP, local-port, remote-IP, remote-port, protocol). If any element in the tuple is different, then this is a completely independent connection.
3.) When a client connects to a server, it picks a random, unused high-order source port. This way, a single client can have up to ~64k connections to the server for the same destination port.
So, this is really what gets created when a client connects to a server:
Local Computer | Remote Computer | Role
-----------------------------------------------------------
0.0.0.0:80 | <none> | LISTENING
127.0.0.1:80 | 10.1.2.3:<random_port> | ESTABLISHED
First, let's use netstat to see what is happening on this computer. We will use port 500 instead of 80 (because a whole bunch of stuff is happening on port 80 as it is a common port, but functionally it does not make a difference).
netstat -atnp | grep -i ":500 "
As expected, the output is blank. Now let's start a web server:
sudo python3 -m http.server 500
Now, here is the output of running netstat again:
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:500 0.0.0.0:* LISTEN -
So now there is one process that is actively listening (State: LISTEN) on port 500. The local address is 0.0.0.0, which is code for "listening for all ip addresses". An easy mistake to make is to only listen on port 127.0.0.1, which will only accept connections from the current computer. So this is not a connection, this just means that a process requested to bind() to port IP, and that process is responsible for handling all connections to that port. This hints to the limitation that there can only be one process per computer listening on a port (there are ways to get around that using multiplexing, but this is a much more complicated topic). If a web-server is listening on port 80, it cannot share that port with other web-servers.
So now, let's connect a user to our machine:
quicknet -m tcp -t localhost:500 -p Test payload.
This is a simple script (https://github.com/grokit/quickweb) that opens a TCP socket, sends the payload ("Test payload." in this case), waits a few seconds and disconnects. Doing netstat again while this is happening displays the following:
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:500 0.0.0.0:* LISTEN -
tcp 0 0 192.168.1.10:500 192.168.1.13:54240 ESTABLISHED -
If you connect with another client and do netstat again, you will see the following:
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:500 0.0.0.0:* LISTEN -
tcp 0 0 192.168.1.10:500 192.168.1.13:26813 ESTABLISHED -
... that is, the client used another random port for the connection. So there is never confusion between the IP addresses.
os.Mkdir
is used to create a single directory. To create a folder path, instead try using:
os.MkdirAll(folderPath, os.ModePerm)
func MkdirAll(path string, perm FileMode) error
MkdirAll creates a directory named path, along with any necessary parents, and returns nil, or else returns an error. The permission bits perm are used for all directories that MkdirAll creates. If path is already a directory, MkdirAll does nothing and returns nil.
Edit:
Updated to correctly use os.ModePerm
instead.
For concatenation of file paths, use package path/filepath
as described in @Chris' answer.
You likely need to re-start VNC on both ends. i.e. when you say "restarted VNC", you probably just mean the client. But what about the other end? You likely need to re-start that end too. The root cause is likely a conflict. Many apps spy on the clipboard when they shouldn't. And many apps are not forgiving when they go to open the clipboard and can't. Robust ones will retry, others will simply not anticipate a failure and then they get fouled up and need to be restarted. Could be VNC, or it could be another app that's "listening" to the clipboard viewer chain, where it is obligated to pass along notifications to the other apps in the chain. If the notifications aren't sent, then VNC may not even know that there has been a clipboard update.
Make it 100% of the viewport height:

Works in all modern browsers and IE>=9, see here for more info.
Use Shell "program file path file path you want to open"
.
Example:
Shell "c:\windows\system32\mspaint.exe c:users\admin\x.jpg"
For most multiline strings using an XML element with an inner CDATA block is easier to avoid having to escape anything for simple raw string data.
Dim s as string = <s><![CDATA[Line 1
line 2
line 3]]></s>.Value
Note that I've seen many people state the same format but without the wrapping "< s >" tag (just the CDATA block) but visual studio Automatic formatting seams to alter the leading whitespace of each line then. I think this is due to the object inheritance structure behind the Linq "X" objects. CDATA is not a "Container", the outer block is an XElement which inherits from XContainer.
As far as I know, there isn't anything on the HTML specs because browsers aren't supposed to do anything different for these fields. They just send them as they normally do and PHP is the one that does the parsing into an array, as do other languages.
This should work in older browsers and with UTF-16 characters like .
This should be the most compatible solution. However, it is less performant than a for
loop would be.
I generated the regular expression using regexpu
var str = 'My String ';_x000D_
var regEx = /(?:[\0-\uD7FF\uE000-\uFFFF]|[\uD800-\uDBFF][\uDC00-\uDFFF]|[\uD800-\uDBFF](?![\uDC00-\uDFFF])|(?:[^\uD800-\uDBFF]|^)[\uDC00-\uDFFF])/g_x000D_
_x000D_
_x000D_
str.replace(regEx, function (char) {_x000D_
console.log(char)_x000D_
});
_x000D_
Hope this helps!
protected void Application_Start(object sender, EventArgs e)
{
string path = Server.MapPath("/");
//or
string path2 = Server.MapPath("~");
//depends on your application needs
}
Here is another way not depending on a library but using a regex.
You can use this single line:
text.matches("\\A\\p{ASCII}*\\z")
Whole example program:
public class Main {
public static void main(String[] args) {
char nonAscii = 0x00FF;
String asciiText = "Hello";
String nonAsciiText = "Buy: " + nonAscii;
System.out.println(asciiText.matches("\\A\\p{ASCII}*\\z"));
System.out.println(nonAsciiText.matches("\\A\\p{ASCII}*\\z"));
}
}
Building on N.S's answer, I have a PowerShell script that exports to a CSV file with the quote marks around the field and comma separated and it skips the header information in the file.
add-pssnapin sqlserverprovidersnapin100
add-pssnapin sqlservercmdletsnapin100
$qry = @"
Select
*
From
tablename
"@
Invoke-Sqlcmd -ServerInstance Server -Database DBName -Query $qry | convertto-CSV -notype | select -skip 1 > "full path and filename.csv"
The first two lines enable the ability to use the Invoke-SqlCmd command-let.
This works: Change your file to:
LLKKKKKKKKMMMMMMMMNNNNNNNNNNNNN GGGGGGGGGHHHHHHHHHHHHHHHHHHHHEEEEEEEE
Then:
file = open("file.txt")
line = file.read()
words = line.split()
This creates a list named words
that equals:
['LLKKKKKKKKMMMMMMMMNNNNNNNNNNNNN', 'GGGGGGGGGHHHHHHHHHHHHHHHHHHHHEEEEEEEE']
That got rid of the "\n". To answer the part about the brackets getting in your way, just do this:
for word in words: # Assuming words is the list above
print word # Prints each word in file on a different line
Or:
print words[0] + ",", words[1] # Note that the "+" symbol indicates no spaces
#The comma not in parentheses indicates a space
This returns:
LLKKKKKKKKMMMMMMMMNNNNNNNNNNNNN, GGGGGGGGGHHHHHHHHHHHHHHHHHHHHEEEEEEEE
Great answer above. Another way is to use the great yaml jq wrapper tool, yq at https://github.com/kislyuk/yq
Save your JSON example to a file, say ex.json and then
yq -y '.' ex.json

For a css-only solution, try setting pointer-events: none
on the input.
The variable can be declared in the .js
file and simply referenced in the HTML file.
My version of helpers.js
:
var myFunctionWasCalled = false;
function doFoo()
{
if (!myFunctionWasCalled) {
alert("doFoo called for the very first time!");
myFunctionWasCalled = true;
}
else {
alert("doFoo called again");
}
}
And a page to test it:
<html>
<head>
<title>Test Page</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<script type="text/javascript" src="helpers.js"></script>
</head>
<body>
<p>myFunctionWasCalled is
<script type="text/javascript">document.write(myFunctionWasCalled);</script>
</p>
<script type="text/javascript">doFoo();</script>
<p>Some stuff in between</p>
<script type="text/javascript">doFoo();</script>
<p>myFunctionWasCalled is
<script type="text/javascript">document.write(myFunctionWasCalled);</script>
</p>
</body>
</html>
You'll see the test alert()
will display two different things, and the value written to the page will be different the second time.
While making a selector
, always keep the default state at the end, otherwise only default state would be used. You need to reorder the items in your selector as:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:color="@android:color/holo_blue_dark" />
<item android:color="@android:color/darker_gray" />
</selector>
And the state to be used with BottomNavigationBar
is state_checked
not state_selected
.
Look at Compare-Object
Compare-Object $a1 $b1 | ForEach-Object { $_.InputObject }
Or if you would like to know where the object belongs to, then look at SideIndicator:
$a1=@(1,2,3,4,5,8)
$b1=@(1,2,3,4,5,6)
Compare-Object $a1 $b1
If you are using emulator then try reset it and if you at mobile first uninstall the application then switch off the developer mode, and then switch it on the problem will be solved.
Following code add image attribute height and width to each image on the page.

Please note there are two very nice color schemes by default in IDEA 10.
The one that is included is named Railcasts. It is included with the Ruby plugin (free official plugin, install via plugin manager).
It's a one-liner with mutate_at
:
dat %>% mutate_at("l1", factor) %>% mutate_at("l2", as.numeric)
There are some issues with the scripts above:
shift "removes" the parameter $1, otherwise, "push" will read it and "misunderstand it".
My tip :
git config --global alias.acpp '!git add -A && branchatu="$(git symbolic-ref HEAD 2>/dev/null)" && branchatu=${branchatu##refs/heads/} && git commit -m "$1" && shift && git pull -u origin $branchatu && git push -u origin $branchatu'
You want to apply a custom formatting rule. The "Applies to" field should be your entire row (If you want to format row 5, put in =$5:$5
. The custom formula should be =IF($B$5="X", TRUE, FALSE)
, shown in the example below.
You need to install a plugin, There is a free one from the eclipse foundation called the Web Tools Platform. It has all the development functionality that you'll need.
You can get the Java EE Edition of eclipse with has it pre-installed.
To create and run your first servlet:
doGet()
method.That should do it for you. You can use ant to build here if that's what you'd like but eclipse will actually do the build and automatically deploy the changes to the server. With Tomcat you might have to restart it every now and again depending on the change.
You can use Programmatic Navigation.In order to go back, you use this:
router.go(n)
Where n can be positive or negative (to go back). This is the same as history.back().So you can have your element like this:
<a @click="$router.go(-1)">back</a>
CSS has different pseudo selector by which you can achieve such effect. In your case you can use
:active : if you want background color only when the button is clicked and don't want to persist.
:focus: if you want background color untill the focus is on the button.
button:active{
background:olive;
}
and
button:focus{
background:olive;
}
P.S.: Please don't give the number in Id
attribute of html elements.
You forgot the HTTP part:
window.location.href = "http://example.com/Registration/Success/";
Use the enumerate
built-in function: http://docs.python.org/library/functions.html#enumerate
You can't access your fieldname
as a global variable. Use document.getElementById:
function updateInput(ish){
document.getElementById("fieldname").value = ish;
}
and
onchange="updateInput(this.value)"
Personally, I find it easiest to modify commit messages after the fact in vi
(or whatever your git editor of choice is) rather than on the command line, by doing git commit --amend
right after git commit
.
Nick's answer works great and the default settings are nice, but you can more fully control the scrolling by completing all of the optional settings.
here is what it looks like in the API:
.animate( properties [, duration] [, easing] [, complete] )
so you could do something like this:
.animate(
{scrollTop:'300px'},
300,
swing,
function(){
alert(animation complete! - your custom code here!);
}
)
here is the jQuery .animate function api page: http://api.jquery.com/animate/
You are close, but the parameter you pass to SecureStringToBSTR
must be a SecureString
. You appear to be passing the result of ConvertFrom-SecureString
, which is an encrypted standard string. So call ConvertTo-SecureString
on this before passing to SecureStringToBSTR
.
$SecurePassword = ConvertTo-SecureString $PlainPassword -AsPlainText -Force
$BSTR = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($SecurePassword)
$UnsecurePassword = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)
There is comma missing in your tuple.
insert the comma between the tuples as shown:
pack_size = (('1', '1'),('3', '3'),(b, b),(h, h),(d, d), (e, e),(r, r))
Do the same for all
function escapeRegExp(string) {
return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string
}

escapeRegExp("All of these should be escaped: \ ^ $ * + ? . ( ) | { } [ ]");
>>> "All of these should be escaped: \\ \^ \$ \* \+ \? \. \( \) \| \{ \} \[ \] "
(NOTE: the above is not the original answer; it was edited to show the one from MDN. This means it does not match what you will find in the code in the below npm, and does not match what is shown in the below long answer. The comments are also now confusing. My recommendation: use the above, or get it from MDN, and ignore the rest of this answer. -Darren,Nov 2019)

I just re-invented this wheel today, and thought I'd share it.
This implementation does not require any changes to the code that defines the constants, which can be enumerations or #define
s or anything else that devolves to an integer - in my case I had symbols defined in terms of other symbols. It also works well with sparse values. It even allows multiple names for the same value, returning the first one always. The only downside is that it requires you to make a table of the constants, which might become out-of-date as new ones are added for example.
struct IdAndName
{
int id;
const char * name;
bool operator<(const IdAndName &rhs) const { return id < rhs.id; }
};
#define ID_AND_NAME(x) { x, #x }
const char * IdToName(int id, IdAndName *table_begin, IdAndName *table_end)
{
if ((table_end - table_begin) > 1 && table_begin[0].id > table_begin[1].id)
std::stable_sort(table_begin, table_end);
IdAndName searchee = { id, NULL };
IdAndName *p = std::lower_bound(table_begin, table_end, searchee);
return (p == table_end || p->id != id) ? NULL : p->name;
}
template<int N>
const char * IdToName(int id, IdAndName (&table)[N])
{
return IdToName(id, &table[0], &table[N]);
}
An example of how you'd use it:
static IdAndName WindowsErrorTable[] =
{
ID_AND_NAME(INT_MAX), // flag value to indicate unsorted table
ID_AND_NAME(NO_ERROR),
ID_AND_NAME(ERROR_INVALID_FUNCTION),
ID_AND_NAME(ERROR_FILE_NOT_FOUND),
ID_AND_NAME(ERROR_PATH_NOT_FOUND),
ID_AND_NAME(ERROR_TOO_MANY_OPEN_FILES),
ID_AND_NAME(ERROR_ACCESS_DENIED),
ID_AND_NAME(ERROR_INVALID_HANDLE),
ID_AND_NAME(ERROR_ARENA_TRASHED),
ID_AND_NAME(ERROR_NOT_ENOUGH_MEMORY),
ID_AND_NAME(ERROR_INVALID_BLOCK),
ID_AND_NAME(ERROR_BAD_ENVIRONMENT),
ID_AND_NAME(ERROR_BAD_FORMAT),
ID_AND_NAME(ERROR_INVALID_ACCESS),
ID_AND_NAME(ERROR_INVALID_DATA),
ID_AND_NAME(ERROR_INVALID_DRIVE),
ID_AND_NAME(ERROR_CURRENT_DIRECTORY),
ID_AND_NAME(ERROR_NOT_SAME_DEVICE),
ID_AND_NAME(ERROR_NO_MORE_FILES)
};
const char * error_name = IdToName(GetLastError(), WindowsErrorTable);
The IdToName
function relies on std::lower_bound
to do quick lookups, which requires the table to be sorted. If the first two entries in the table are out of order, the function will sort it automatically.
Edit: A comment made me think of another way of using the same principle. A macro simplifies the generation of a big switch
statement.
#define ID_AND_NAME(x) case x: return #x
const char * WindowsErrorToName(int id)
{
switch(id)
{
ID_AND_NAME(ERROR_INVALID_FUNCTION);
ID_AND_NAME(ERROR_FILE_NOT_FOUND);
ID_AND_NAME(ERROR_PATH_NOT_FOUND);
ID_AND_NAME(ERROR_TOO_MANY_OPEN_FILES);
ID_AND_NAME(ERROR_ACCESS_DENIED);
ID_AND_NAME(ERROR_INVALID_HANDLE);
ID_AND_NAME(ERROR_ARENA_TRASHED);
ID_AND_NAME(ERROR_NOT_ENOUGH_MEMORY);
ID_AND_NAME(ERROR_INVALID_BLOCK);
ID_AND_NAME(ERROR_BAD_ENVIRONMENT);
ID_AND_NAME(ERROR_BAD_FORMAT);
ID_AND_NAME(ERROR_INVALID_ACCESS);
ID_AND_NAME(ERROR_INVALID_DATA);
ID_AND_NAME(ERROR_INVALID_DRIVE);
ID_AND_NAME(ERROR_CURRENT_DIRECTORY);
ID_AND_NAME(ERROR_NOT_SAME_DEVICE);
ID_AND_NAME(ERROR_NO_MORE_FILES);
default: return NULL;
}
}
strSearch in this case is probably null (not simply empty).
Try using
String.IsNullOrEmpty(strSearch)
if you are just trying to determine if the string doesn't have any contents.
If you use underscore.js then these type of null and undefined check are hidden by the library.
So your code will look like this -
var currentData = new Array();
if (_.isEmpty(currentData)) return false;
Ti.API.info("is exists " + currentData[index]);
return true;
It looks much more readable now.
This returns a numpy array:
arr = df["cluster"].to_numpy()
This returns a numpy array of unique values:
unique_arr = df["cluster"].unique()
You can also use numpy to get the unique values, although there are differences between the two methods:
arr = df["cluster"].to_numpy()
unique_arr = np.unique(arr)
Try this query:
SELECT sysdate FROM schema_name.table_name;
This should display the timestamp that you might need.
That error message generally means there are other processes connected to the DB. Try running this to see which are connected:
exec sp_who
That will return you the process and then you should be able to run:
kill [XXX]
Where [xxx] is the spid
of the process you're trying to kill.
Then you can run your above statement.
Good luck.
A common pattern is to create a feature with a route, a lazy loaded module, and a component.
Route: myapp.com/feature
app-routing.module.ts
{ path: 'feature', loadChildren: () => import('./my-feature/my-feature.module').then(m => m.MyFeatureModule) },
File structure:
app
+---my-feature
¦ ¦ my-feature-routing.module.ts
¦ ¦ my-feature.component.html
¦ ¦ my-feature.component.css
¦ ¦ my-feature.component.spec.ts
¦ ¦ my-feature.component.ts
¦ ¦ my-feature.module.ts
This can all be done in the cli with:
ng generate module my-feature --module app.module --route feature
Or shorter
ng g m my-feature --module app.module --route feature
Or if you leave out the name the cli will prompt you for it. Very useful when you need to create several features
ng g m --module app.module --route feature
To remove all files from a directory, first you need to list all files in the directory using fs.readdir
, then you can use fs.unlink
to remove each file. Also fs.readdir
will give just the file names, you need to concat with the directory name to get the full path.
Here is an example
const fs = require('fs');
const path = require('path');
const directory = 'test';
fs.readdir(directory, (err, files) => {
if (err) throw err;
for (const file of files) {
fs.unlink(path.join(directory, file), err => {
if (err) throw err;
});
}
});
There is a recursive
flag that you can use in rmdir
to remove all the files recursively. See nodejs docs for more information.
const fs = require('fs').promises;

this will make you to answer the question
OP's sample code is incorrect.
Endian conversion works at the bit and 8-bit byte level. Most endian issues deal with the byte level. OP code is doing a endian change at the 4-bit nibble level. Recommend instead:
// Swap endian (big to little) or (little to big)
uint32_t num = 9;
uint32_t b0,b1,b2,b3;
uint32_t res;
b0 = (num & 0x000000ff) << 24u;
b1 = (num & 0x0000ff00) << 8u;
b2 = (num & 0x00ff0000) >> 8u;
b3 = (num & 0xff000000) >> 24u;
res = b0 | b1 | b2 | b3;
printf("%" PRIX32 "\n", res);
If performance is truly important, the particular processor would need to be known. Otherwise, leave it to the compiler.
[Edit] OP added a comment that changes things.
"32bit numerical value represented by the hexadecimal representation (st uv wx yz) shall be recorded in a four-byte field as (st uv wx yz)."
It appears in this case, the endian of the 32-bit number is unknown and the result needs to be store in memory in little endian order.
uint32_t num = 9;
uint8_t b[4];
b[0] = (uint8_t) (num >> 0u);
b[1] = (uint8_t) (num >> 8u);
b[2] = (uint8_t) (num >> 16u);
b[3] = (uint8_t) (num >> 24u);
[2016 Edit] Simplification
... The type of the result is that of the promoted left operand.... Bitwise shift operators C11 §6.5.7 3
Using a u
after the shift constants (right operands) results in the same as without it.
b3 = (num & 0xff000000) >> 24u;
b[3] = (uint8_t) (num >> 24u);
// same as
b3 = (num & 0xff000000) >> 24;
b[3] = (uint8_t) (num >> 24);

Yes, you can apply CSS to SVG, but you need to match the element, just as when styling HTML. If you just want to apply it to all SVG paths, you could use, for example:
?path {
fill: blue;
}?
External CSS appears to override the path's fill
attribute, at least in WebKit and Gecko-based browsers I tested. Of course, if you write, say, <path style="fill: green">
then that will override external CSS as well.
Here is what I did to solve just by 2 ways:
make ID column as int
type
if you are using autogenerate in ID dont assing value in the setter of ID. If your mapping the some then sometimes autogenetated ID is not concedered. (I dont know why)
try using @GeneratedValue(strategy=GenerationType.SEQUENCE)
if possible
For Excel 2010 it should be UTF-8. Instruction by MS :
http://msdn.microsoft.com/en-us/library/bb507946:
"The basic document structure of a SpreadsheetML document consists of the Sheets and Sheet elements, which reference the worksheets in the Workbook. A separate XML file is created for each Worksheet. For example, the SpreadsheetML for a workbook that has two worksheets name MySheet1 and MySheet2 is located in the Workbook.xml file and is shown in the following code example.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<workbook xmlns=http://schemas.openxmlformats.org/spreadsheetml/2006/main xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
<sheets>
<sheet name="MySheet1" sheetId="1" r:id="rId1" />
<sheet name="MySheet2" sheetId="2" r:id="rId2" />
</sheets>
</workbook>
The worksheet XML files contain one or more block level elements such as SheetData. sheetData represents the cell table and contains one or more Row elements. A row contains one or more Cell elements. Each cell contains a CellValue element that represents the value of the cell. For example, the SpreadsheetML for the first worksheet in a workbook, that only has the value 100 in cell A1, is located in the Sheet1.xml file and is shown in the following code example.
<?xml version="1.0" encoding="UTF-8" ?>
<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
<sheetData>
<row r="1">
<c r="A1">
<v>100</v>
</c>
</row>
</sheetData>
</worksheet>
"
Detection of cell encodings:
It's easy, you should set server http response header first. The problem is not with your front-end javascript code. You need to return this header:
Access-Control-Allow-Origin:*
or
Access-Control-Allow-Origin:your domain
In Apache config files, the code is like this:
Header set Access-Control-Allow-Origin "*"
In nodejs,the code is like this:
res.setHeader('Access-Control-Allow-Origin','*');
The others are (from git help log
):
--date=(relative|local|default|iso|rfc|short|raw)
Only takes effect for dates shown in human-readable format,
such as when using "--pretty". log.date config variable
sets a default value for log command’s --date option.
--date=relative shows dates relative to the current time, e.g. "2 hours ago".
--date=local shows timestamps in user’s local timezone.
--date=iso (or --date=iso8601) shows timestamps in ISO 8601 format.
--date=rfc (or --date=rfc2822) shows timestamps in RFC 2822 format,
often found in E-mail messages.
--date=short shows only date but not time, in YYYY-MM-DD format.
--date=raw shows the date in the internal raw git format %s %z format.
--date=default shows timestamps in the original timezone
(either committer’s or author’s).
There is no built-in way that I know of to create a custom format, but you can do some shell magic.
timestamp=`git log -n1 --format="%at"`
my_date=`perl -e "print scalar localtime ($timestamp)"`
git log -n1 --pretty=format:"Blah-blah $my_date"
The first step here gets you a millisecond timestamp. You can change the second line to format that timestamp however you want. This example gives you something similar to --date=local
, with a padded day.
And if you want permanent effect without typing this every time, try
git config log.date iso
Or, for effect on all your git usage with this account
git config --global log.date iso
If you do not want to include the jquery library you can simple do the following
a) ad an iframe, size 0px so it is not visible, href is blank
b) execute this within your js code function
window.frames['iframename'].location.replace('http://....your.php');
This will execute the php script and you can for example make a database update...
I found I could improve the situation a little with CSS dedicated to Webkit (Safari, Chrome). However, I had to set a fixed width and height on the field because the font change will resize the field.
@media screen and (-webkit-min-device-pixel-ratio:0){ /* START WEBKIT */
INPUT[type="password"]{
font-family:Verdana,sans-serif;
height:28px;
font-size:19px;
width:223px;
padding:5px;
}
} /* END WEBKIT */
With Ctrl + Shift + L you can open the "key assist", where you can find all the shortcuts.
JSON:-
For POST request using json object it can be configured by selecting
Body -> raw -> application/json
Form Data(For Normal content POST):- multipart/form-data
For normal POST request (using multipart/form-data) it can be configured by selecting
Body -> form-data
Single liner to create a sudo user with home directory and password.
