Yes you can start with the Wikipedia article explaining the Big O notation, which in a nutshell is a way of describing the "efficiency" (upper bound of complexity) of different type of algorithms. Or you can look at an earlier answer where this is explained in simple english
Hey i figured it out shortly after. For some reason I was just having a brain fart.
image.frame = CGRectMake(0 , 0, self.view.frame.width, self.view.frame.height * 0.2)
Here is the code sample for Creating a segue programmatically
:
class ViewController: UIViewController {
...
// 1. Define the Segue
private var commonSegue: UIStoryboardSegue!
...
override func viewDidLoad() {
...
// 2. Initialize the Segue
self.commonSegue = UIStoryboardSegue(identifier: "CommonSegue", source: ..., destination: ...) {
self.commonSegue.source.showDetailViewController(self.commonSegue.destination, sender: self)
}
...
}
...
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// 4. Prepare to perform the Segue
if self.commonSegue == segue {
...
}
...
}
...
func actionFunction() {
// 3. Perform the Segue
self.prepare(for: self.commonSegue, sender: self)
self.commonSegue.perform()
}
...
}

// packing an array of 4 bytes to an int, big endian, minimal parentheses

int fromByteArray(byte[] bytes) {
return bytes[0] << 24 | (bytes[1] & 0xFF) << 16 | (bytes[2] & 0xFF) << 8 | (bytes[3] & 0xFF);
}
// packing an array of 4 bytes to an int, big endian, clean code
int fromByteArray(byte[] bytes) {
return ((bytes[0] & 0xFF) << 24) |
((bytes[1] & 0xFF) << 16) |
((bytes[2] & 0xFF) << 8 ) |
((bytes[3] & 0xFF) << 0 );
}
When packing signed bytes into an int, each byte needs to be masked off because it is sign-extended to 32 bits (rather than zero-extended) due to the arithmetic promotion rule (described in JLS, Conversions and Promotions).
There's an interesting puzzle related to this described in Java Puzzlers ("A Big Delight in Every Byte") by Joshua Bloch and Neal Gafter . When comparing a byte value to an int value, the byte is sign-extended to an int and then this value is compared to the other int
byte[] bytes = (…)
if (bytes[0] == 0xFF) {
// dead code, bytes[0] is in the range [-128,127] and thus never equal to 255
}
Note that all numeric types are signed in Java with exception to char being a 16-bit unsigned integer type.
It's because size_t can be anything other than an int (maybe a struct). The idea is that it decouples it's job from the underlying type.
A pure RESTful API should use the underlying protocol standard features:
For HTTP, the RESTful API should comply with existing HTTP standard headers. Adding a new HTTP header violates the REST principles. Do not re-invent the wheel, use all the standard features in HTTP/1.1 standards - including status response codes, headers, and so on. RESTFul web services should leverage and rely upon the HTTP standards.
RESTful services MUST be STATELESS. Any tricks, such as token based authentication that attempts to remember the state of previous REST requests on the server violates the REST principles. Again, this is a MUST; that is, if you web server saves any request/response context related information on the server in attempt to establish any sort of session on the server, then your web service is NOT Stateless. And if it is NOT stateless it is NOT RESTFul.
Bottom-line: For authentication/authorization purposes you should use HTTP standard authorization header. That is, you should add the HTTP authorization / authentication header in each subsequent request that needs to be authenticated. The REST API should follow the HTTP Authentication Scheme standards.The specifics of how this header should be formatted are defined in the RFC 2616 HTTP 1.1 standards – section 14.8 Authorization of RFC 2616, and in the RFC 2617 HTTP Authentication: Basic and Digest Access Authentication.
I have developed a RESTful service for the Cisco Prime Performance Manager application. Search Google for the REST API document that I wrote for that application for more details about RESTFul API compliance here. In that implementation, I have chosen to use HTTP "Basic" Authorization scheme. - check out version 1.5 or above of that REST API document, and search for authorization in the document.
I found a solution that is more efficient than currently accepted answer, because current answer forces all list elements to be refreshed. My solution will refresh only one element (that was touched) by calling adapters getView and recycling current view which adds even more efficiency.
mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// Edit object data that is represented in Viewat at list's "position"
view = mAdapter.getView(position, view, parent);
}
});
assertTrue
will fail if the second parameter evaluates to false
(in other words, it ensures that the value is true). assertFalse
does the opposite.
assertTrue("This will succeed.", true);
assertTrue("This will fail!", false);
assertFalse("This will succeed.", false);
assertFalse("This will fail!", true);
As with many other things, the best way to become familiar with these methods is to just experiment :-).
Here is how you can do it for array of arrays of primitives of variable depth:
// If a is array:
// then call cpArr(a) for each e;
// else return a
const cpArr = a => Array.isArray(a) && a.map(e => cpArr(e)) || a;
let src = [[1,2,3], [4, ["five", "six", 7], true], 8, 9, false];
let dst = cpArr(src);
Ran the sample of these commands:
git config --global user.email "[email protected]"
git config --global user.name "focus1"
Footnote:
[email protected] === email address used to login to your github account.
focus === your github username
Now in FileZilla, create a new Account 1. Host is the FTP Address - e.g. ftp.somewhere.com 2. Protocol is "SFTP-SSH File Transfer Protocol" 3. User ID is your Bluehost User Id 4. Password is your Bluehost Password 5. Click "Connect" to establish a connection with Directory Listing!
This resolve the issue with 3.10 for me. And I'm glad to have the Secure Access for all of my future file transfers. It should prevent security issues in the future.
var details = {
'userName': '[email protected]',
'password': 'Password!',
'grant_type': 'password'
};
var formBody = [];
for (var property in details) {
var encodedKey = encodeURIComponent(property);
var encodedValue = encodeURIComponent(details[property]);
formBody.push(encodedKey + "=" + encodedValue);
}
formBody = formBody.join("&");
fetch('http://identity.azurewebsites.net' + '/token', {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/x-www-form-urlencoded'
},
body: formBody
})
it is so helpful for me and works without any error

Regarding your second requirement - you might be able to utilise the onerror event, ie. <img onerror="some javascript;"...
Update:
You could also try iterating through document.images
in the dom. There is a complete
boolean property which you might be able to use. I don't know for sure whether this will be suitable, but might be worth investigating.
var objectList = objects.ToList();
objectList[0].SimpleInt=5;
This will update the original object as well. The new list will contain references to the objects contained within it, just like the original list. You can change the elements either and the update will be reflected in the other.
Now if you update a list (adding or deleting an item) that will not be reflected in the other list.
Make sure Blog
has methods equals(Object)
and hashCode()
defined, and addAll(list)
then to a new HashSet()
, or new LinkedHashSet()
if the order is important.
Better yet, use a Set
instead of a List
from the start, since you obviously don't want duplicates, it's better that your data model reflects that rather than having to remove them after the fact.
Since nobody so far felt fit to point out why what you're trying doesn't work:
NA == NA
doesn't return TRUE
, it returns NA
(since comparing to undefined values should yield an undefined result). apply
on an atomic vector. You can't use apply
to loop over the elements in a column. a$x
, which is just the column (an atomic vector).I'd fix up 3. to get to a$x[is.na(a$x)] <- 0
I am using this code, which I find more practical than the accepted answer above:
List<Thing> thingList = new ArrayList<>(thingSet);
thingList.sort((thing1, thing2) -> thing1.getName().compareToIgnoreCase(thing2.getName()));

Why would UPDLOCK block selects? The Lock Compatibility Matrix clearly shows N
for the S/U and U/S contention, as in No Conflict.
As for the HOLDLOCK hint the documentation states:
HOLDLOCK: Is equivalent to SERIALIZABLE. For more information, see SERIALIZABLE later in this topic.
...
SERIALIZABLE: ... The scan is performed with the same semantics as a transaction running at the SERIALIZABLE isolation level...
and the Transaction Isolation Level topic explains what SERIALIZABLE means:
No other transactions can modify data that has been read by the current transaction until the current transaction completes.
Other transactions cannot insert new rows with key values that would fall in the range of keys read by any statements in the current transaction until the current transaction completes.
Therefore the behavior you see is perfectly explained by the product documentation:
SELECT * FROM dbo.Test WITH (UPDLOCK) WHERE ...
The real question is what are you trying to achieve? Playing with lock hints w/o an absolute complete 110% understanding of the locking semantics is begging for trouble...
After OP edit:
I would like to select rows from a table and prevent the data in that table from being modified while I am processing it.
The you should use one of the higher transaction isolation levels. REPEATABLE READ will prevent the data you read from being modified. SERIALIZABLE will prevent the data you read from being modified and new data from being inserted. Using transaction isolation levels is the right approach, as opposed to using query hints. Kendra Little has a nice poster exlaining the isolation levels.

Jackson appears to support some amount of JSON parsing straight from an InputStream
. My understanding is that it runs on Android and is fairly quick. On the other hand, it is an extra JAR to include with your app, increasing download and on-flash size.
If you really want to micro optimise your code your best approach is always benchmarking.

api.get("/url", function);

You need a gutter between two div gutter can be made as following
margin(gutter) = width - gutter size E.g margin = calc(70% - 2em)
<body bgcolor="gray">
<section id="main">
<div id="left">
Something here
</div>
<div id="right">
Someone there
</div>
</section>
</body>
<style>
body{
font-size: 10px;
}
#main div{
float: left;
background-color:#ffffff;
width: calc(50% - 1.5em);
margin-left: 1.5em;
}
</style>
If my firebug profiler work fine (and i know how to use it well), this:
$('#communitymode').attr('checked')
is faster than
$('#communitymode').is('checked')
You can try on this page :)
And then you can use it like
if($('#communitymode').attr('checked')===true) {
// do something
}
The dir
wrapper can wrap, any other step, and it all works inside a steps
block, for example:
steps {
sh "pwd"
dir('your-sub-directory') {
sh "pwd"
}
sh "pwd"
}

You can use reduce()

I had this problem too. Doing alt+enter and then asking to either re-run or disable Spring inspection on the effected line fixed it. This only seems to have become an issue after the 13.4 update.
The best way to visualize this is to use a packet analyzer like Wireshark and follow the TCP stream. HTTP simply uses TCP to send a stream of data starting with a few lines of HTTP headers. Often this data is easy to read because it consists of HTML, CSS, or XML, but it can be any type of data that gets transfered over the internet (Executables, Images, Video, etc).
For a GET request, your computer requests a specific URL and the web server usually responds with a 200 status code and the the content of the webpage is sent directly after the HTTP response headers. This content is the same content you would see if you viewed the source of the webpage in your browser. The query string you mentioned is just part of the URL and gets included in the HTTP GET request header that your computer sends to the web server. Below is an example of an HTTP GET request to http://accel91.citrix.com:8000/OA_HTML/OALogout.jsp?menu=Y, followed by a 302 redirect response from the server. Some of the HTTP Headers are wrapped due to the size of the viewing window (these really only take one line each), and the 302 redirect includes a simple HTML webpage with a link to the redirected webpage (Most browsers will automatically redirect any 302 response to the URL listed in the Location header instead of displaying the HTML response):
For a POST request, you may still have a query string, but this is uncommon and does not have anything to do with the data that you are POSTing. Instead, the data is included directly after the HTTP headers that your browser sends to the server, similar to the 200 response that the web server uses to respond to a GET request. In the case of POSTing a simple web form this data is encoded using the same URL encoding that a query string uses, but if you are using a SOAP web service it could also be encoded using a multi-part MIME format and XML data.
For example here is what an HTTP POST to an XML based SOAP web service located at http://192.168.24.23:8090/msh looks like in Wireshark Follow TCP Stream:

ws WebSocket server and client for node.js. One of the fastest libraries if not the fastest one.
websocket-node WebSocket server and client for node.js
websocket-driver-node WebSocket server and client protocol parser node.js - used in faye-websocket-node
faye-websocket-node WebSocket server and client for node.js - used in faye and sockjs
socket.io WebSocket server and client for node.js + client for browsers + (v0 has newest to oldest fallbacks, v1 of Socket.io uses engine.io) + channels - used in stack.io. Client library tries to reconnect upon disconnection.
sockjs WebSocket server and client for node.js and others + client for browsers + newest to oldest fallbacks
faye WebSocket server and client for node.js and others + client for browsers + fallbacks + support for other server-side languages
deepstream.io clusterable realtime server that handles WebSockets & TCP connections and provides data-sync, pub/sub and request/response
socketcluster WebSocket server cluster which makes use of all CPU cores on your machine. For example, if you were to use an xlarge Amazon EC2 instance with 32 cores, you would be able to handle almost 32 times the traffic on a single instance.
primus Provides a common API for most of the libraries above for easy switching + stability improvements for all of them.
When to use:
use the basic WebSocket servers when you want to use the native WebSocket implementations on the clientside, beware of the browser incompatabilities
use the fallback libraries when you care about browser fallbacks
use the full featured libraries when you care about channels
use primus when you have no idea about what to use, are not in the mood for rewriting your application when you need to switch frameworks because of changing project requirements or need additional connection stability.
Where to test:
Firecamp is a GUI testing environment for SocketIO, WS and all major real-time technology. Debug the real-time events while you're developing it.
localStorage
is something that is kept on the client side. There is no data transmitted to the server side.

You get this error when the function isn't on the MATLAB path or in pwd.
First, make sure that you are able to find the function using:
>> which divrat
c:\work\divrat\divrat.m
If it returns:
>> which divrat
'divrat' not found.
It is not on the MATLAB path or in PWD.
Second, make sure that the directory that contains divrat
is on the MATLAB path using the PATH
command. It may be that a directory that you thought was on the path isn't actually on the path.
Finally, make sure you aren't using a "private" directory. If divrat
is in a directory named private, it will be accessible by functions in the parent directory, but not from the MATLAB command line:
>> foo
ans =
1
>> divrat(1,1)
??? Undefined function or method 'divrat' for input arguments of type 'double'.
>> which -all divrat
c:\work\divrat\private\divrat.m % Private to divrat
You can not sort TreeMap on values.
A Red-Black tree based NavigableMap implementation. The map is sorted according to the natural ordering of its keys, or by a Comparator provided at map creation time, depending on which constructor is used You will need to provide
comparator
forComparator<? super K>
so your comparator should compare on keys.
To provide sort on values you will need SortedSet. Use
SortedSet<Map.Entry<String, Double>> sortedset = new TreeSet<Map.Entry<String, Double>>(
new Comparator<Map.Entry<String, Double>>() {
@Override
public int compare(Map.Entry<String, Double> e1,
Map.Entry<String, Double> e2) {
return e1.getValue().compareTo(e2.getValue());
}
});
sortedset.addAll(myMap.entrySet());
To give you an example
SortedMap<String, Double> myMap = new TreeMap<String, Double>();
myMap.put("a", 10.0);
myMap.put("b", 9.0);
myMap.put("c", 11.0);
myMap.put("d", 2.0);
sortedset.addAll(myMap.entrySet());
System.out.println(sortedset);
Output:
[d=2.0, b=9.0, a=10.0, c=11.0]

If you use webpack devServer the simplest way is to set disableHostCheck, check webpack doc like this
devServer: {
contentBase: path.join(__dirname, './dist'),
compress: true,
host: 'localhost',
// host: '0.0.0.0',
port: 8080,
disableHostCheck: true //for ngrok
},
Try configuration at /config/application.rb:
config.middleware.insert_before 0, "Rack::Cors" do
allow do

end
end
I finally got a very easy solution to this.
use these Support libraries in app level gradle,
compile 'com.android.support:appcompat-v7:26.0.2'
compile 'com.android.support:support-v4:26.0.2'
then create a directory named "font" inside the res folder
After that, reference that font from xml like this
<Button
android:id="@+id/btn_choose_employee"
android:layout_width="140dp"
android:layout_height="40dp"
android:layout_centerInParent="true"
android:background="@drawable/rounded_red_btn"
android:onClick="btnEmployeeClickedAction"
android:text="@string/searching_jobs"
android:textAllCaps="false"
android:textColor="@color/white"
android:fontFamily="@font/times_new_roman_test"
/>
In this example, times_new_roman_test is a font ttf file from that font directory

JSON is purely meant to be a data description language. As noted on http://www.json.org, it is a "lightweight data-interchange format." - not a programming language.
Per http://en.wikipedia.org/wiki/JSON, the "basic types" supported are:
null
It depends on which level you selected in your log4j configuration file.
<Loggers>
<Root level="info">
...
If your level is "info" (by default), logger.debug(...)
will not be printed in your console.
However, if your level is "debug", it will.
Depending on the criticality level of your code, you should use the most accurate level among the following ones :
ALL < TRACE < DEBUG < INFO < WARN < ERROR < FATAL < OFF
This worked for me:
GRANT USAGE ON *.* TO 'username'@'localhost';
DROP USER 'username'@'localhost';
This creates the user if it doesn't already exist (and grants it a harmless privilege), then deletes it either way. Found solution here: http://bugs.mysql.com/bug.php?id=19166

Don't be scared off by the number of commands, I've not met anyone who used more than a couple dozen at most. I find it indispensable, because when I'm thinking about code I'm thinking about text, moving to thinking about mice just messes me up. The big tricks, I think, are to learn it a little at a time, and don't be hesitant to play around - the undo features is great for exploring its behaviors.
Also, if you get deeply into it, vim is scriptable. The possibilities are literally endless.

Perhaps you should consider using a HashSet.
From the MSDN link:
using System;
using System.Collections.Generic;
class Program
{
static void Main()
{
HashSet<int> evenNumbers = new HashSet<int>();
HashSet<int> oddNumbers = new HashSet<int>();
for (int i = 0; i < 5; i++)
{
// Populate numbers with just even numbers.
evenNumbers.Add(i * 2);
// Populate oddNumbers with just odd numbers.
oddNumbers.Add((i * 2) + 1);
}
Console.Write("evenNumbers contains {0} elements: ", evenNumbers.Count);
DisplaySet(evenNumbers);
Console.Write("oddNumbers contains {0} elements: ", oddNumbers.Count);
DisplaySet(oddNumbers);
// Create a new HashSet populated with even numbers.
HashSet<int> numbers = new HashSet<int>(evenNumbers);
Console.WriteLine("numbers UnionWith oddNumbers...");
numbers.UnionWith(oddNumbers);
Console.Write("numbers contains {0} elements: ", numbers.Count);
DisplaySet(numbers);
}
private static void DisplaySet(HashSet<int> set)
{
Console.Write("{");
foreach (int i in set)
{
Console.Write(" {0}", i);
}
Console.WriteLine(" }");
}
}
/* This example produces output similar to the following:
* evenNumbers contains 5 elements: { 0 2 4 6 8 }
* oddNumbers contains 5 elements: { 1 3 5 7 9 }
* numbers UnionWith oddNumbers...
* numbers contains 10 elements: { 0 2 4 6 8 1 3 5 7 9 }

All the open streams & connections need to be properly closed, so the next time we try to use the urlConnection object, it does not throw an error. As an example, the following code change fixed the error for me.
Before:
OutputStream out = new BufferedOutputStream(urlConnection.getOutputStream());
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(out));
bw.write("Some text");
bw.close();
out.close();
After:
OutputStream os = urlConnection.getOutputStream();
OutputStream out = new BufferedOutputStream(os);
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(out));
bw.write("Some text");
bw.close();

I found a good example showing the differences between all hibernate save methods:
http://www.journaldev.com/3481/hibernate-session-merge-vs-update-save-saveorupdate-persist-example
In brief, according to the above link:
save()
persist()
saveOrUpdate()
Can be used with or without the transaction, and just like save(), if its used without the transaction, mapped entities wont be saved un;ess we flush the session.
Results into insert or update queries based on the provided data. If the data is present in the database, update query is executed.
update()
merge()
Also for practical examples of all these, please refer to the link I mentioned above, it shows examples for all these different methods.
This is almost like the other answer but you don't need a scatter
plot at all, you can simply specify a scatter-plot-like format (fmt
-parameter) for errorbar
:
import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [1, 4, 9, 16]
e = [0.5, 1., 1.5, 2.]
plt.errorbar(x, y, yerr=e, fmt='o')
plt.show()
Result:
A list of the avaiable fmt
parameters can be found for example in the plot
documentation:
character description
'-' solid line style
'--' dashed line style
'-.' dash-dot line style
':' dotted line style
'.' point marker
',' pixel marker
'o' circle marker
'v' triangle_down marker
'^' triangle_up marker
'<' triangle_left marker
'>' triangle_right marker
'1' tri_down marker
'2' tri_up marker
'3' tri_left marker
'4' tri_right marker
's' square marker
'p' pentagon marker
'*' star marker
'h' hexagon1 marker
'H' hexagon2 marker
'+' plus marker
'x' x marker
'D' diamond marker
'd' thin_diamond marker
'|' vline marker
'_' hline marker
You didn't specify a GradientType
:
background: #f0f0f0; /* Old browsers */
background: -moz-linear-gradient(top, #ffffff 0%, #eeeeee 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#ffffff), color-stop(100%,#eeeeee)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top, #ffffff 0%,#eeeeee 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top, #ffffff 0%,#eeeeee 100%); /* Opera11.10+ */
background: -ms-linear-gradient(top, #ffffff 0%,#eeeeee 100%); /* IE10+ */

background: linear-gradient(top, #ffffff 0%,#eeeeee 100%); /* W3C */
In my own experience where I needed to try and find out what some old VB6 programs were doing, I turned to Process Explorer (Sysinternals). I did the following:
This didn't show the actual functions, but it listed their names, folders of where files were being copied from and to and if it accessed a DB it would also display the connection string. Enough to help you get an idea, but may be useless for complex programs. The programs I was looking at were pretty basic (no pun intended).
YMMV.
If you are providing mappings like this:
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Configurations.Add(new ClassificationMap());
modelBuilder.Configurations.Add(new CompanyMap());
modelBuilder.Configurations.Add(new GroupMap());
....
}
Remember to add the map for BaseCs.
You won't get a compile error if it is missing. But you will get a runtime error when you use the entity.
I love to work with Volley. To save development time i tried to write small handy library Gloxey Netwok Manager to setup Volley with my project. It includes JSON parser and different other methods that helps to check network availability.
Use ConnectionManager.class
in which different methods for Volley String and Volley JSON request are available.
You can make requests of GET, PUT, POST, DELETE with or without header. You can read full documentation here.
Just put this line in your gradle file.
dependencies {
compile 'io.gloxey.gnm:network-manager:1.0.1'
}
Method GET (without header)
ConnectionManager.volleyStringRequest(context, isDialog, progressDialogView, requestURL, volleyResponseInterface);
Configuration Description
Context Context
isDialog If true dialog will appear, otherwise not.
progressView For custom progress view supply your progress view id and make isDialog true. otherwise pass null.
requestURL Pass your API URL.
volleyResponseInterface Callback for response.
Example
ConnectionManager.volleyStringRequest(this, false, null, "url", new VolleyResponse() {
@Override
public void onResponse(String _response) {
/**
* Handle Response
*/
}
@Override
public void onErrorResponse(VolleyError error) {
/**
* handle Volley Error
*/
}
@Override
public void isNetwork(boolean connected) {
/**
* True if internet is connected otherwise false
*/
}
});
Method POST/PUT/DELETE (without header)
ConnectionManager.volleyStringRequest(context, isDialog, progressDialogView, requestURL, requestMethod, params, volleyResponseInterface);
Example
Use Method : Request.Method.POST
Request.Method.PUT
Request.Method.DELETE
Your params :
HashMap<String, String> params = new HashMap<>();
params.put("param 1", "value");
params.put("param 2", "value");
ConnectionManager.volleyStringRequest(this, true, null, "url", Request.Method.POST, params, new VolleyResponse() {
@Override
public void onResponse(String _response) {
/**
* Handle Response
*/
}
@Override
public void onErrorResponse(VolleyError error) {
/**
* handle Volley Error
*/
}
@Override
public void isNetwork(boolean connected) {
/**
* True if internet is connected otherwise false
*/
}
});
Feel free to use gloxey json parser to parse your api response.
YourModel yourModel = GloxeyJsonParser.getInstance().parse(stringResponse, YourModel.class);
Example
ConnectionManager.volleyStringRequest(this, false, null, "url", new VolleyResponse() {
@Override
public void onResponse(String _response) {
/**
* Handle Response
*/
try {
YourModel yourModel = GloxeyJsonParser.getInstance().parse(_response, YourModel.class);
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void onErrorResponse(VolleyError error) {
/**
* handle Volley Error
*/
if (error instanceof TimeoutError || error instanceof NoConnectionError) {
showSnackBar(parentLayout, getString(R.string.internet_not_found), getString(R.string.retry), new View.OnClickListener() {
@Override
public void onClick(View view) {
//handle retry button
}
});
} else if (error instanceof AuthFailureError) {
} else if (error instanceof ServerError) {
} else if (error instanceof NetworkError) {
} else if (error instanceof ParseError) {
}
}
@Override
public void isNetwork(boolean connected) {
/**
* True if internet is connected otherwise false
*/
if (!connected) {
showSnackBar(parentLayout, getString(R.string.internet_not_found), getString(R.string.retry), new View.OnClickListener() {
@Override
public void onClick(View view) {
//Handle retry button
}
});
}
});
public void showSnackBar(View view, String message) {
Snackbar.make(view, message, Snackbar.LENGTH_LONG).show();
}
public void showSnackBar(View view, String message, String actionText, View.OnClickListener onClickListener) {
Snackbar.make(view, message, Snackbar.LENGTH_LONG).setAction(actionText, onClickListener).show();
}
Use database field type BLOB to store arrays.
Ref: http://us.php.net/manual/en/function.serialize.php
Return Values
Returns a string containing a byte-stream representation of value that can be stored anywhere.
Note that this is a binary string which may include null bytes, and needs to be stored and handled as such. For example, serialize() output should generally be stored in a BLOB field in a database, rather than a CHAR or TEXT field.
Use the new CSS viewport units vw
and vh
(viewport width / viewport height)
Resize vertically and horizontally and you'll see that the element will always fill the maximum viewport size without breaking the ratio and without scrollbars!

Instead of beginUpdates()
/endUpdates()
, the recommended call is now:
tableView.performBatchUpdates(nil, completion: nil)
Apple says, regarding beginUpdates/endUpdates: "Use the performBatchUpdates(_:completion:) method instead of this one whenever possible."
See: https://developer.apple.com/documentation/uikit/uitableview/1614908-beginupdates
From the documentation:
In order to execute a command and have it not hang your PHP script while
it runs, the program you run must not output back to PHP. To do this,
redirect both stdout and stderr to /dev/null, then background it.
> /dev/null 2>&1 &
In order to execute a command and have
it spawned off as another process that
is not dependent on the Apache thread
to keep running (will not die if
somebody cancels the page) run this:
exec('bash -c "exec nohup setsid your_command > /dev/null 2>&1 &"');
Java has evolved since this issue was first brought up. You can match all manner of unicode space characters by using the \p{Zs}
group.
Thus if you wanted to replace one or more exotic spaces with a plain space you could do this:
String txt = "whatever my string is";
txt.replaceAll("\\p{Zs}+", " ")
Also worth knowing, if you've used the trim()
string function you should take a look at the (relatively new) strip()
, stripLeading()
, and stripTrailing()
functions on strings. The can help you trim off all sorts of squirrely white space characters. For more information on what what space is included, see Java's Character.isWhitespace()
function.
In kibana 4.0.2 there is no --log-file option. If I start kibana as a service with systemctl start kibana

If you manually write out the query with static date values (e.g. '2009-10-29 13:13:07.440') do you get any rows?
So, you are saying that the following two queries produce correct results:
SELECT DISTINCT pat.PublicationID
FROM PubAdvTransData AS pat
INNER JOIN PubAdvertiser AS pa
ON pat.AdvTransID = pa.AdvTransID
WHERE (pat.LastAdDate > '2009-10-29 13:13:07.440') AND (pa.AdvertiserID = 12345))
DECLARE @sp_Date DATETIME
SET @sp_Date = '2009-10-29 13:13:07.440'
SELECT DISTINCT pat.PublicationID
FROM PubAdvTransData AS pat
INNER JOIN PubAdvertiser AS pa
ON pat.AdvTransID = pa.AdvTransID
WHERE (pat.LastAdDate > @sp_Date) AND (pa.AdvertiserID = 12345))
Have you tried Refinements?
module Nothingness
refine String do
alias_method :nothing?, :empty?
end
refine NilClass do
alias_method :nothing?, :nil?
end
end
using Nothingness
return my_string.nothing?

The best way to send data from a parent component to a child is using props.
props
props
(array or object) in the child<child :name="variableOnParent">
See demo below:
Vue.component('child-comp', {
props: ['message'], // declare the props
template: '<p>At child-comp, using props in the template: {{ message }}</p>',
mounted: function () {
console.log('The props are also available in JS:', this.message);
}
})
new Vue({
el: '#app',
data: {
variableAtParent: 'DATA FROM PARENT!'
}
})
_x000D_
<script src="https://unpkg.com/[email protected]/dist/vue.min.js"></script>
<div id="app">
<p>At Parent: {{ variableAtParent }}<br>And is reactive (edit it) <input v-model="variableAtParent"></p>
<child-comp :message="variableAtParent"></child-comp>

You can stash your local changes first, then pull, then pop the stash.
git stash
git pull origin master
git stash pop
Anything that overrides changes from remote will have conflicts which you will have to manually resolve.
I came across this thread because I also had the error Could not create SSL/TLS secure channel. In my case, I was attempting to access a Siebel configuration REST API from PowerShell using Invoke-RestMethod
, and none of the suggestions above helped.
Eventually I stumbled across the cause of my problem: the server I was contacting required client certificate authentication.
To make the calls work, I had to provide the client certificate (including the private key) with the -Certificate
parameter:
$Pwd = 'certificatepassword'
$Pfx = New-Object -TypeName 'System.Security.Cryptography.X509Certificates.X509Certificate2'
$Pfx.Import('clientcert.p12', $Pwd, 'Exportable,PersistKeySet')
Invoke-RestMethod -Uri 'https://your.rest.host/api/' -Certificate $Pfx -OtherParam ...
Hopefully my experience might help someone else who has my particular flavour of this problem.
$array = str_split("0123456789bcdfghjkmnpqrstvwxyz");
str_split takes an optional 2nd param, the chunk length (default 1), so you can do things like:
$array = str_split("aabbccdd", 2);
// $array[0] = aa
// $array[1] = bb
// $array[2] = cc etc ...
You can also get at parts of your string by treating it as an array:
$string = "hello";
echo $string[1];
// outputs "e"
Your condition id !== 0
will always be different that zero because you are assigning a string value. On pages where the element with id views_slideshow_controls_text_next_slideshow-block
is not found, you will still try to append the img element, which causes the Cannot read property 'appendChild' of null
error.
Instead of assigning a string value, you can assign the DOM element and verify if it exists within the page.
window.onload = function loadContIcons() {
var elem = document.createElement("img");
elem.src = "http://arno.agnian.com/sites/all/themes/agnian/images/up.png";
elem.setAttribute("class", "up_icon");
var container = document.getElementById("views_slideshow_controls_text_next_slideshow-block");
if (container !== null) {
container.appendChild(elem);
} else console.log("aaaaa");
var elem1 = document.createElement("img");
elem1.src = "http://arno.agnian.com/sites/all/themes/agnian/images/down.png";
elem1.setAttribute("class", "down_icon");
container = document.getElementById("views_slideshow_controls_text_previous_slideshow-block");
if (container !== null) {
container.appendChild(elem1);
} else console.log("aaaaa");
}
Adding my answer, because it elaborates the idea that you can SELECT multiple columns from the table from which you subquery.
Here I needed the the most recently cast cote and it's associated information.
I first tried simply to SELECT the max(votedate) along with vote, itemid, userid etc., but while the query would return the max votedate, it would also return the a random row for the other information. Hard to see among a bunch of 1s and 0s.
This worked well:
$query = "
SELECT t1.itemid, t1.itemtext, t2.vote, t2.votedate, t2.userid
FROM
(
SELECT itemid, itemtext FROM oc_item ) t1
LEFT JOIN
(
SELECT vote, votedate, itemid,userid FROM oc_votes
WHERE votedate IN
(select max(votedate) FROM oc_votes group by itemid)
AND userid=:userid) t2
ON (t1.itemid = t2.itemid)
order by itemid ASC
";
The subquery in the WHERE clause WHERE votedate IN (select max(votedate) FROM oc_votes group by itemid) returns one record - the record with the max vote date.
Just add layout_weight="1" to in your linearLayout which having Buttons.
Edit :- let me make it simple
follow something like below, tags name may not be correct, it is just an Idea
<LL>// Top Parrent LinearLayout
<LL1 height="fill_parent" weight="1" "other tags as requirement"> <TV /><Butons /></LL1> // this layout will fill your screen.
<LL2 height="wrap_content" weight="1" orientation="Horizontal" "other tags as requirement"> <BT1 /><BT2/ ></LL2> // this layout gonna take lower part of button height of your screen
<LL/> TOP PARENT CLOSED
Yes, a struct
is identical to a class
except for the default access level (member-wise and inheritance-wise). (and the extra meaning class
carries when used with a template)
Every functionality supported by a class is consequently supported by a struct. You'd use methods the same as you'd use them for a class.
struct foo {
int bar;
foo() : bar(3) {} //look, a constructor
int getBar()
{
return bar;
}
};
foo f;
int y = f.getBar(); // y is 3
One typical usage:
|
is used to set a certain bit to 1
&
is used to test or clear a certain bit
Set a bit (where n is the bit number, and 0 is the least significant bit):
unsigned char a |= (1 << n);
Clear a bit:
unsigned char b &= ~(1 << n);
Toggle a bit:
unsigned char c ^= (1 << n);
Test a bit:
unsigned char e = d & (1 << n);
Take the case of your list for example:
x | 2
is used to set bit 1 of x
to 1
x & 1
is used to test if bit 0 of x
is 1 or 0
Importing .cer
certificate file downloaded from browser (open the url and dig for details) into cacerts keystore in java_home\jre\lib\security
worked for me, as opposed to attemps to generate and use my own keystore.
java_home\jre\lib\security
cmd
and CTRL+SHIFT+ENTERyourAliasName
and path\to\certificate.cer
respectively) ..\..\bin\keytool -import -trustcacerts -keystore cacerts -storepass changeit -noprompt -alias yourAliasName -file path\to\certificate.cer
This way you don't have to specify any additional JVM options and the certificate should be recognized by the JRE.

urllib2 provides some extra functionality, namely the urlopen()
function can allow you to specify headers (normally you'd have had to use httplib in the past, which is far more verbose.) More importantly though, urllib2 provides the Request
class, which allows for a more declarative approach to doing a request:
r = Request(url='http://www.mysite.com')
r.add_header('User-Agent', 'awesome fetcher')
r.add_data(urllib.urlencode({'foo': 'bar'})
response = urlopen(r)
Note that urlencode()
is only in urllib, not urllib2.
There are also handlers for implementing more advanced URL support in urllib2. The short answer is, unless you're working with legacy code, you probably want to use the URL opener from urllib2, but you still need to import into urllib for some of the utility functions.
Bonus answer With Google App Engine, you can use any of httplib, urllib or urllib2, but all of them are just wrappers for Google's URL Fetch API. That is, you are still subject to the same limitations such as ports, protocols, and the length of the response allowed. You can use the core of the libraries as you would expect for retrieving HTTP URLs, though.
Try this:
.navbar {
position: relative;
}
.brand {
position: absolute;
left: 50%;
margin-left: -50px !important; /* 50% of your logo width */
display: block;
}
Centering your logo by 50% and minus half of your logo width so that it won't have problem when zooming in and out.

if you want the original style of your Ui to remain and the title bar to be removed with no effect on that, you have to remove the title bar in your activity rather than the manifest. leave the original theme style that you had in the manifest and in each activity that you want no title bar use this.requestWindowFeature(Window.FEATURE_NO_TITLE);
in the oncreate()
method before setcontentview()
like this:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_signup);
...
}
=COUNTIF(A:A;"lisa")
You can replace the criteria with cell references from Column B
Change JDK version to 1.8
Another thing to note is that if you want a absolute element to be confined to a parent element then you need to set the parent element's position to relative. That will keep the child element contained within the parent element and it won't be "relative" to the entire window.
I wrote a blog post that gives a simple example that creates the following affect:
That has a green div that is absolutely positioned to the bottom of the parent yellow div.

Important: This issue drove me crazy for a couple days and I couldn't figure out what was going on with my curl & openssl installations. I finally figured out that it was my intermediate certificate (in my case, GoDaddy) which was out of date. I went back to my godaddy SSL admin panel, downloaded the new intermediate certificate, and the issue disappeared.
I'm sure this is the issue for some of you.
Apparently, GoDaddy had changed their intermediate certificate at some point, due to scurity issues, as they now display this warning:
"Please be sure to use the new SHA-2 intermediate certificates included in your downloaded bundle."
Hope this helps some of you, because I was going nuts and this cleaned up the issue on ALL my servers.
If you want to return the original string untouched if it does not contain the search character then you can use an anonymous function (a closure):
var streetaddress=(function(s){var i=s.indexOf(',');
return i==-1 ? s : s.substr(0,i);})(addy);
This can be made more generic:
var streetaddress=(function(s,c){var i=s.indexOf(c);
return i==-1 ? s : s.substr(0,i);})(addy,',');
Even after all these time, it might help someone. This is simple JS solution.
JS
let date = new Date();
let today = date.toISOString().substr(0, 10);
//console.log("Today: ", today);//test
document.getElementById("form-container").innerHTML =
'<input type="date" name="myDate" value="' + today + '" >';//inject field
HTML
<form id="form-container"></form>
Similar solution works in Angular without any additional library to convert date format. For Angular (code is shortened due to common component code):
//so in myComponent.ts
//Import.... @Component...etc...
date: Date = new Date();
today: String; //<- note String
//more const ...
export class MyComponent implements OnInit {
//constructor, etc....
ngOnInit() {
this.today = this.date.toISOString().substr(0, 10);
}
}
//so in component.html
<input type="date" [(ngModel)]="today" />
As this error comes when you are trying to insert non-numeric value into a numeric column in db it seems that your last field might be numeric and you are trying to send it as a string in database. check your last value.
Note use of /x
modifier.

JPA will use all properties of the class, unless you specifically mark them with @Transient
:
@Transient
private String agencyName;
The @Column
annotation is purely optional, and is there to let you override the auto-generated column name. Furthermore, the length
attribute of @Column
is only used when auto-generating table definitions, it has no effect on the runtime.
if ( values > 0 ) {
//you got a positive value
}else{
//you got a negative or zero value

I'm using Laravel 5.7 and tried all of the above answers but nothing seemed to be hitting the spot.
For me, it was a rather simple fix by removing the cache files created by Laravel.
It seemed that my changes were not being reflected, and therefore my application wasn't seeing the routes.
A bit overkill, but I decided to reset all my cache at the same time using the following commands:
php artisan route:clear
php artisan view:clear
php artisan cache:clear
The main one here is the first command which will delete the bootstrap/cache/routes.php
file.
The second command will remove the cached files for the views that are stored in the storage/framework/cache
folder.
Finally, the last command will clear the application cache.
Use the square bracket syntax:
if (!empty($row["title"])) {
$catList[$row["datasource_id"]] = $row["title"];
}
$row["datasource_id"]
is the key for where the value of $row["title"]
is stored in.
If I understand correctly, you're looking for a multi-line representation, for readability? You want something like a here-string in other languages. Javascript can come close with this:
var x =
"<div> \
<span> \
<p> \
some text \
</p> \
</div>";
Check this:
The TEXTAREA element creates a multi-line text input control

In projects that use the Gradle build system, what you want to change is the applicationId
in the build.gradle file. The build system uses this value to override anything specified by hand in the manifest file when it does the manifest merge and build.
For example, your module's build.gradle file looks something like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
// CHANGE THE APPLICATION ID BELOW
applicationId "com.example.fred.myapplication"
minSdkVersion 10
targetSdkVersion 20
versionCode 1
versionName "1.0"
}
}
applicationId
is the name the build system uses for the property that eventually gets written to the package
attribute of the manifest
tag in the manifest file. It was renamed to prevent confusion with the Java package name (which you have also tried to modify), which has nothing to do with it.
Could use below to get UTF8 without BOM
$MyFile | Out-File -Encoding ASCII
I think the accepted way is better, but I guess this might work as well
function getElementByClass(&$parentNode, $tagName, $className, $offset = 0) {
$response = false;
$childNodeList = $parentNode->getElementsByTagName($tagName);
$tagCount = 0;
for ($i = 0; $i < $childNodeList->length; $i++) {
$temp = $childNodeList->item($i);
if (stripos($temp->getAttribute('class'), $className) !== false) {
if ($tagCount == $offset) {
$response = $temp;
break;
}
$tagCount++;
}
}
return $response;
}
Suppose you have service reference of the name localhost
in your web.config
so you can go as follows
localhost.Service objWebService = newlocalhost.Service();
localhost.AuthSoapHd objAuthSoapHeader = newlocalhost.AuthSoapHd();
string strUsrName =ConfigurationManager.AppSettings["UserName"];
string strPassword =ConfigurationManager.AppSettings["Password"];
objAuthSoapHeader.strUserName = strUsrName;
objAuthSoapHeader.strPassword = strPassword;
objWebService.AuthSoapHdValue =objAuthSoapHeader;
string str = objWebService.HelloWorld();
Response.Write(str);
If you want to set width dynamically with variable than use [] braces instead {{}}:

<div [style.width.%]="[widthVal]" [style.height.%]="[heightVal]"></div>
Here is a link to another post/thread. I was able run this script to automate registration of Python 2.7. (Make sure to run it from the Python 2.x .exe
you want to register!)
To register Python 3.x I had to modify the print
syntax and import winreg
(instead of _winreg
), then run the Python 3 .exe
.
public List<DealsCategory> DealCategory { get; set; }
int categoryid = Convert.ToInt16(dealsModel.DealCategory.Select(x => x.Id));
The real answer is this simplest and easiest ....
String white = "#ffffff";
int whiteInt = Color.parseColor(white);
Add this one to your header file:
template <typename T> vector<T> concat(vector<T> &a, vector<T> &b) {
vector<T> ret = vector<T>();
copy(a.begin(), a.end(), back_inserter(ret));
copy(b.begin(), b.end(), back_inserter(ret));
return ret;
}
and use it this way:
vector<int> a = vector<int>();
vector<int> b = vector<int>();
a.push_back(1);
a.push_back(2);
b.push_back(62);
vector<int> r = concat(a, b);
r will contain [1,2,62]

Addition to previous answer make sure that your curl installation supports https.
You can use curl --version
to get information about supported protocols.
If your curl supports https follow the previous answer.
curl --cert certificate_path:password https://www.example.com
If it does not support https, you need to install a cURL version that supports https.

For those of you who can't use the HtmlAgilityPack, .NETs XML reader is an option. This can fail on well formatted HTML though so always add a catch with regx as a backup. Note this is NOT fast, but it does provide a nice opportunity for old school step through debugging.
public static string RemoveHTMLTags(string content)
{
var cleaned = string.Empty;
try
{
StringBuilder textOnly = new StringBuilder();
using (var reader = XmlNodeReader.Create(new System.IO.StringReader("<xml>" + content + "</xml>")))
{
while (reader.Read())
{
if (reader.NodeType == XmlNodeType.Text)
textOnly.Append(reader.ReadContentAsString());
}
}
cleaned = textOnly.ToString();
}
catch
{
//A tag is probably not closed. fallback to regex string clean.
string textOnly = string.Empty;
Regex tagRemove = new Regex(@"<[^>]*(>|$)");
Regex compressSpaces = new Regex(@"[\s\r\n]+");
textOnly = tagRemove.Replace(content, string.Empty);
textOnly = compressSpaces.Replace(textOnly, " ");
cleaned = textOnly;
}
return cleaned;

If you push for example image to some API and want the result address(response) back you could do:

response = requests.post(url, data=data, files=files)
current_url = response.text
print(response.text)
I got the same question here. If the document is huge, it is not a good idea to use XmlDocument. The fact is that the first element is the root element, based on which XmlReader can be used to get the root element. Using XmlReader will be much more efficient than using XmlDocument as it doesn't require load the whole document into memory.
using (XmlReader reader = XmlReader.Create(<your_xml_file>)) {
while (reader.Read()) {
// first element is the root element
if (reader.NodeType == XmlNodeType.Element) {
System.Console.WriteLine(reader.Name);
break;
}
}
}

Sometimes, although you add <uses-permission android:name="android.permission.INTERNET" />

If this is just going to open up the user's client to send the email, why not let them compose it there as well. You lose the ability to track what they are sending, but if that's not important, then just collect the addresses and subject and pop up the client to let the user fill in the body.
No, there isn't a boolean type in Oracle Database, but you can do this way:
You can put a check constraint on a column.
If your table hasn't a check column, you can add it:
ALTER TABLE table_name
ADD column_name_check char(1) DEFAULT '1';
When you add a register, by default this column get 1.
Here you put a check that limit the column value, just only put 1 or 0
ALTER TABLE table_name ADD
CONSTRAINT name_constraint
column_name_check (ONOFF in ( '1', '0' ));

You should use Comparable instead of a Comparator if a default sort is what your looking for.
See here, this may be of some help - When should a class be Comparable and/or Comparator?
Try this -
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
public class TestSort {
public static void main(String args[]){
ToSort toSort1 = new ToSort(new Float(3), "3");
ToSort toSort2 = new ToSort(new Float(6), "6");
ToSort toSort3 = new ToSort(new Float(9), "9");
ToSort toSort4 = new ToSort(new Float(1), "1");
ToSort toSort5 = new ToSort(new Float(5), "5");
ToSort toSort6 = new ToSort(new Float(0), "0");
ToSort toSort7 = new ToSort(new Float(3), "3");
ToSort toSort8 = new ToSort(new Float(-3), "-3");
List<ToSort> sortList = new ArrayList<ToSort>();
sortList.add(toSort1);
sortList.add(toSort2);
sortList.add(toSort3);
sortList.add(toSort4);
sortList.add(toSort5);
sortList.add(toSort6);
sortList.add(toSort7);
sortList.add(toSort8);
Collections.sort(sortList);
for(ToSort toSort : sortList){
System.out.println(toSort.toString());
}
}
}
public class ToSort implements Comparable<ToSort> {
private Float val;
private String id;
public ToSort(Float val, String id){
this.val = val;
this.id = id;
}
@Override
public int compareTo(ToSort f) {
if (val.floatValue() > f.val.floatValue()) {
return 1;
}
else if (val.floatValue() < f.val.floatValue()) {

C++20 will have "uniform container erasure", and you'll be able to write:

Here's my go at answering this,
so first you will need to convert the timestamp to an actual Ruby Date/Time. If you receive it just as a string or int from facebook, you will need to do something like this:
my_date = Time.at(timestamp_from_facebook.to_i)
OK, so now assuming you already have your date object...
to_formatted_s is a handy Ruby function that turns dates into formatted strings.
Here are some examples of its usage:
time = Time.now # => Thu Jan 18 06:10:17 CST 2007
time.to_formatted_s(:time) # => "06:10"
time.to_s(:time) # => "06:10"
time.to_formatted_s(:db) # => "2007-01-18 06:10:17"
time.to_formatted_s(:number) # => "20070118061017"
time.to_formatted_s(:short) # => "18 Jan 06:10"
time.to_formatted_s(:long) # => "January 18, 2007 06:10"
time.to_formatted_s(:long_ordinal) # => "January 18th, 2007 06:10"
time.to_formatted_s(:rfc822) # => "Thu, 18 Jan 2007 06:10:17 -0600"
As you can see: :db, :number, :short ... are custom date formats.
To add your own custom format, you can create this file: config/initializers/time_formats.rb and add your own formats there, for example here's one:
Date::DATE_FORMATS[:month_day_comma_year] = "%B %e, %Y" # January 28, 2015
Where :month_day_comma_year is your format's name (you can change this to anything you want), and where %B %e, %Y is unix date format.
Here's a quick cheatsheet on unix date syntax, so you can quickly setup your custom format:
From http://linux.die.net/man/3/strftime
%a - The abbreviated weekday name (``Sun'')
%A - The full weekday name (``Sunday'')
%b - The abbreviated month name (``Jan'')
%B - The full month name (``January'')
%c - The preferred local date and time representation
%d - Day of the month (01..31)
%e - Day of the month without leading 0 (1..31)
%g - Year in YY (00-99)
%H - Hour of the day, 24-hour clock (00..23)
%I - Hour of the day, 12-hour clock (01..12)
%j - Day of the year (001..366)
%m - Month of the year (01..12)
%M - Minute of the hour (00..59)
%p - Meridian indicator (``AM'' or ``PM'')
%S - Second of the minute (00..60)
%U - Week number of the current year,
starting with the first Sunday as the first
day of the first week (00..53)
%W - Week number of the current year,
starting with the first Monday as the first
day of the first week (00..53)
%w - Day of the week (Sunday is 0, 0..6)
%x - Preferred representation for the date alone, no time
%X - Preferred representation for the time alone, no date
%y - Year without a century (00..99)
%Y - Year with century
%Z - Time zone name
%% - Literal ``%'' character
t = Time.now
t.strftime("Printed on %m/%d/%Y") #=> "Printed on 04/09/2003"
t.strftime("at %I:%M%p") #=> "at 08:56AM"
Hope this helped you. I've also made a github gist of this little guide, in case anyone prefers.
A simple example that will clear both during executing script or inside script while calling a function.
#!/bin/bash
echo "parameterized function example"
function print_param_value(){
value1="${1}" # $1 represent first argument
value2="${2}" # $2 represent second argument
echo "param 1 is ${value1}" # As string
echo "param 2 is ${value2}"
sum=$(($value1+$value2)) # Process them as number
echo "The sum of two value is ${sum}"
}
print_param_value "6" "4" # Space-separated value
# You can also pass parameters during executing the script
print_param_value "$1" "$2" # Parameter $1 and $2 during execution
# Suppose our script name is "param_example".
# Call it like this:
#
# ./param_example 5 5
#
# Now the parameters will be $1=5 and $2=5

As a newbie in React world, I came across a similar issues where I could not edit
the textarea and struggled
with binding. It's worth knowing about controlled
and uncontrolled
elements when it comes to react.
The value of the following uncontrolled textarea
cannot be changed because of value
<textarea type="text" value="some value"
onChange={(event) => this.handleOnChange(event)}></textarea>
The value of the following uncontrolled textarea
can be changed because of use of defaultValue
or no value attribute
<textarea type="text" defaultValue="sample"
onChange={(event) => this.handleOnChange(event)}></textarea>
<textarea type="text"
onChange={(event) => this.handleOnChange(event)}></textarea>
The value of the following controlled textarea
can be changed because of how
value is mapped to a state as well as the onChange
event listener
<textarea value={this.state.textareaValue}
onChange={(event) => this.handleOnChange(event)}></textarea>
Here is my solution using different syntax. I prefer the auto-bind
than manual binding however, if I were to not use {(event) => this.onXXXX(event)}
then that would cause the content of textarea
to be not editable OR the event.preventDefault()
does not work as expected. Still a lot to learn I suppose.
class Editor extends React.Component {
constructor(props) {
super(props)
this.state = {
textareaValue: ''
}
}
handleOnChange(event) {
this.setState({
textareaValue: event.target.value
})
}
handleOnSubmit(event) {
event.preventDefault();
this.setState({
textareaValue: this.state.textareaValue + ' [Saved on ' + (new Date()).toLocaleString() + ']'
})
}
render() {
return <div>
<form onSubmit={(event) => this.handleOnSubmit(event)}>
<textarea rows={10} cols={30} value={this.state.textareaValue}
onChange={(event) => this.handleOnChange(event)}></textarea>
<br/>
<input type="submit" value="Save"/>
</form>
</div>
}
}
ReactDOM.render(<Editor />, document.getElementById("content"));

Python 2.6 and 3.x supports proper relative imports, where you can avoid doing anything hacky. With this method, you know you are getting a relative import rather than an absolute import. The '..' means, go to the directory above me:
from ..Common import Common
As a caveat, this will only work if you run your python as a module, from outside of the package. For example:
python -m Proj
This method is still commonly used in some situations, where you aren't actually ever 'installing' your package. For example, it's popular with Django users.
You can add Common/ to your sys.path (the list of paths python looks at to import things):
import sys, os
sys.path.append(os.path.join(os.path.dirname(__file__), '..', 'Common'))
import Common
os.path.dirname(__file__)
just gives you the directory that your current python file is in, and then we navigate to 'Common/' the directory and import 'Common' the module.
Use __LINE__
, but what is its type?
LINE The presumed line number (within the current source file) of the current source line (an integer constant).
As an integer constant, code can often assume the value is __LINE__ <= INT_MAX
and so the type is int
.
To print in C, printf()
needs the matching specifier: "%d"
. This is a far lesser concern in C++ with cout
.
Pedantic concern: If the line number exceeds INT_MAX
1 (somewhat conceivable with 16-bit int
), hopefully the compiler will produce a warning. Example:
format '%d' expects argument of type 'int', but argument 2 has type 'long int' [-Wformat=]
Alternatively, code could force wider types to forestall such warnings.
printf("Not logical value at line number %ld\n", (long) __LINE__);
//or
#include <stdint.h>
printf("Not logical value at line number %jd\n", INTMAX_C(__LINE__));
Avoid printf()
To avoid all integer limitations: stringify. Code could directly print without a printf()
call: a nice thing to avoid in error handling2 .
#define xstr(a) str(a)
#define str(a) #a
fprintf(stderr, "Not logical value at line number %s\n", xstr(__LINE__));
fputs("Not logical value at line number " xstr(__LINE__) "\n", stderr);
1 Certainly poor programming practice to have such a large file, yet perhaps machine generated code may go high.
2 In debugging, sometimes code simply is not working as hoped. Calling complex functions like *printf()
can itself incur issues vs. a simple fputs()
.
I had the same problem on Win 7. The solution was to remove following files:
As for .hg/store/lock - there was no such file.
Run the ALTER USER command. Be sure to change password to a strong password of your choosing.
sudo mysql
# Login to mysql`
Run the below command
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
Now you can access it by using the new password.

I would use virtualenv at your HOME directory.
$ sudo easy_install -U virtualenv
$ cd ~
$ virtualenv .
$ bin/pip ...
You could then also alter ~/.(login|profile|bash_profile)
, whichever is right for your shell to add ~/bin to your PATH and then that pip|python|easy_install
would be the one used by default.
Its so simple just use this
header("location:javascript://history.go(-1)");
Its working fine for me
In my case, I had copied some code from another project that was using Automapper - took me ages to work that one out. Just had to add automapper nuget package to project.
Suppose you have an object that looks like this:
var Hogwarts = {
staff : [
'Argus Filch',
'Filius Flitwick',
'Gilderoy Lockhart',
'Minerva McGonagall',
'Poppy Pomfrey',
...
],
students : [
'Hannah Abbott',
'Katie Bell',
'Susan Bones',
'Terry Boot',
'Lavender Brown',
...
]
};
If you want to use the entire staff
array, the proper way to do this, would be to do this:
delete Hogwarts.staff;
Alternatively, you could also do this:
delete Hogwarts['staff'];
Similarly, removing the entire students array would be done by calling delete Hogwarts.students;
or delete Hogwarts['students'];
.
Now, if you want to remove a single staff member or student, the procedure is a bit different, because both properties are arrays themselves.
If you know the index of your staff member, you could simply do this:
Hogwarts.staff.splice(3, 1);
If you do not know the index, you'll also have to do an index search:
Hogwarts.staff.splice(Hogwarts.staff.indexOf('Minerva McGonnagall') - 1, 1);
While you technically can use delete
for an array, using it would result in getting incorrect results when calling for example Hogwarts.staff.length
later on. In other words, delete
would remove the element, but it wouldn't update the value of length
property. Using delete
would also mess up your indexing.
So, when deleting values from an object, always first consider whether you're dealing with object properties or whether you're dealing with array values, and choose the appropriate strategy based on that.
If you want to experiment with this, you can use this Fiddle as a starting point.
Having read above that svg is inline by default, I just added the following to the div:
<div style="text-align:center;">
and it did the trick for me.
Purists may not like it (it’s an image, not text) but in my opinion HTML and CSS screwed up over centring, so I think it’s justified.
Check this out : http://codepen.io/Rowno/pen/Afykb
.carousel-fade {
.carousel-inner {
.item {
opacity: 0;
transition-property: opacity;
}
.active {
opacity: 1;
}
.active.left,
.active.right {
left: 0;
opacity: 0;
z-index: 1;
}
.next.left,
.prev.right {
opacity: 1;
}
}
Works marvellously, I hope it works
If it's a sorted array you could use a Binary search algorithm (O(log n)
). For example, extending the Array-class with this functionality:
class Array
def b_search(e, l = 0, u = length - 1)
return if lower_index > upper_index
midpoint_index = (lower_index + upper_index) / 2
return midpoint_index if self[midpoint_index] == value
if value < self[midpoint_index]
b_search(value, lower_index, upper_index - 1)
else
b_search(value, lower_index + 1, upper_index)
end
end
end
The code overlooks calling the function move_uploaded_file() which would check whether the indicated file is valid for uploading.
You may wish to review a simple example at:
Struct values encode as JSON objects. Each exported struct field becomes a member of the object unless:
The empty values are false, 0, any nil pointer or interface value, and any array, slice, map, or string of length zero. The object's default key string is the struct field name but can be specified in the struct field's tag value. The "json" key in the struct field's tag value is the key name, followed by an optional comma and options.
use:
/^[ A-Za-z0-9_@./#&+-]*$/
You can also use the character class \w to replace A-Za-z0-9_
Change bundle identifier, Straight solution
The condition below:
//Element[@attribute1="abc" and @attribute2="xyz" and Data]
checks for the existence of the element Data within Element and not for element value Data.
Instead you can use
//Element[@attribute1="abc" and @attribute2="xyz" and text()="Data"]
xlim
and ylim
don't cut it here. You need to use expand_limits
, scale_x_continuous
, and scale_y_continuous
. Try:
df <- data.frame(x = 1:5, y = 1:5)
p <- ggplot(df, aes(x, y)) + geom_point()
p <- p + expand_limits(x = 0, y = 0)
p # not what you are looking for
p + scale_x_continuous(expand = c(0, 0)) + scale_y_continuous(expand = c(0, 0))
You may need to adjust things a little to make sure points are not getting cut off (see, for example, the point at x = 5
and y = 5
.
This sometimes happen in RStudio. In order to solve it you can attempt to plot to an external window (Windows-only):
windows() ## create window to plot your file
## ... your plotting code here ...
dev.off()
slice does not change original array it return new array but splice changes the original array.
example: var arr = [1,2,3,4,5,6,7,8];
arr.slice(1,3); // output [2,3] and original array remain same.
arr.splice(1,3); // output [2,3,4] and original array changed to [1,5,6,7,8].
splice method second argument is different from slice method. second argument in splice represent count of elements to remove and in slice it represent end index.
arr.splice(-3,-1); // output [] second argument value should be greater then
0.
arr.splice(-3,-1); // output [6,7] index in minus represent start from last.
-1 represent last element so it start from -3 to -1. Above are major difference between splice and slice method.
I used the Dahnark's code but I also need to change the ToolBar background:
if (dark_ui) {
this.setTheme(R.style.Theme_Dark);
if (Build.VERSION.SDK_INT >= 21) {
getWindow().setNavigationBarColor(getResources().getColor(R.color.Theme_Dark_primary));
getWindow().setStatusBarColor(getResources().getColor(R.color.Theme_Dark_primary_dark));
}
} else {
this.setTheme(R.style.Theme_Light);
}
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.app_bar);
if(dark_ui) {
toolbar.setBackgroundColor(getResources().getColor(R.color.Theme_Dark_primary));
}
Use Imagemagick, or better yet, Ghostscript.
http://www.ibm.com/developerworks/library/l-graf2/#N101C2 has an example for imagemagick:
convert foo.pdf pages-%03d.tiff
http://www.asmail.be/msg0055376363.html has an example for ghostscript:
gs -q -dNOPAUSE -sDEVICE=tiffg4 -sOutputFile=a.tif foo.pdf -c quit
I would install ghostscript and read the man page for gs to see what exact options are needed and experiment.
In our case, the wrong version of the Sysdeo Tomcat plugin for Eclipse 3.5 was being used. The fix:
tomcatPluginV33
instead of tomcatPluginV321
(extract to C:\eclipse\dropins
)DevloaderTomcat7.jar
was placed in the tomcat lib
folderThis problem may have been unique to our environment; but, I'll record it here anyway, for posterity's sake.
To avoid syntax errors, be sure to always put BEGIN
and END
after an IF
clause, eg:
IF (@A!= @SA)
BEGIN
--do stuff
END
IF (@C!= @SC)
BEGIN
--do stuff
END
... and so on. This should work as expected. Imagine BEGIN
and END
keyword as the opening and closing bracket, respectively.

Ok if anyone else is having this problem this may be your answer:
If you are trying to hide absolute positioned elements make sure the container of those absolute positioned elements is relatively positioned.
I think its also possible with adhoc queries you can export result to excel file and then import that file into your datatable object or use it as it is and then import the excel file into the second database have a look at this link this can help u alot.
http://vscontrols.blogspot.com/2010/09/import-and-export-excel-to-sql-server.html
What's important to understand is that val()
for a select
element returns the value of the selected option, but not the number of element as does selectedIndex
in javascript.
To select the option with value="7"
you can simply use:
$('#selectBox').val(7); //this will select the option with value 7.
To deselect the option use an empty array:
$('#selectBox').val([]); //this is the best way to deselect the options
And of course you can select multiple options*:
$('#selectBox').val([1,4,7]); //will select options with values 1,4 and 7
*However to select multiple options, your <select>
element must have a MULTIPLE
attribute, otherwise it won't work.
Visual Studio's search in folders is by far the fastest I've found.
I believe it intelligently searches only text (non-binary) files, and subsequent searches in the same folder are extremely fast, unlike with the other tools (likely the text files fit in the windows disk cache).
VS2010 on a regular hard drive, no SSD, takes 1 minute to search a 20GB folder with 26k files, source code and binaries mixed up. 15k files are searched - the rest are likely skipped due to being binary files. Subsequent searches in the same folder are on the order of seconds (until stuff gets evicted form the cache).
The next closest I've found for the same folder was grepWin. Around 3 minutes. I excluded files larger than 2000KB (default). The "Include binary files" setting seems to do nothing in terms of speeding up the search, it looks like binary files are still touched (bug?), but they don't show up in the search results. Subsequent searches all take the same 3 minutes - can't take advantage of hard drive cache. If I restrict to files smaller than 200k, the initial search is 2.5min and subsequent searches are on the order of seconds, about as fast as VS - in the cache.
Agent Ransack and FileSeek are both very slow on that folder, around 20min, due to searching through everything, including giant multi-gigabyte binary files. They search at about 10-20MB per second according to Resource Monitor.
UPDATE: Agent Ransack can be set to search files of certain sizes, and using the <200KB cutoff it's 1:15min for a fresh search and 5s for subsequent searches. Faster than grepWin and as fast as VS overall. It's actually pretty nice if you want to keep several searches in tabs and you don't want to pollute the VS recently searched folders list, and you want to keep the ability to search binaries, which VS doesn't seem to wanna do. Agent Ransack also creates an explorer context menu entry, so it's easy to launch from a folder. Same as grepWin but nicer UI and faster.
My new search setup is Agent Ransack for contents and Everything for file names (awesome tool, instant results!).
Try this:
^.*(?=.{8,})(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%^&+=])[a-zA-Z0-9@#$%^&+=]*$
This regular expression works for me perfectly.
function myFunction() {
var str = "c1TTTTaTTT@";
var patt = new RegExp("^.*(?=.{8,})(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%^&+=])[a-zA-Z0-9@#$%^&+=]*$");
var res = patt.test(str);
console.log("Is regular matches:", res);
}
The prompt command will echo text to the output:
prompt A useful comment.
select(*) from TableA;
Will be displayed as:
SQL> A useful comment.

Without changing directory:
import os

full_list = [os.path.join(path,i) for i in name_list]
time_sorted_list = sorted(full_list, key=os.path.getmtime)
print time_sorted_list
# if you want just the filenames sorted, simply remove the dir from each
sorted_filename_list = [ os.path.basename(i) for i in time_sorted_list]
print sorted_filename_list
The GUI can be fickle at times. The error you got when using T-SQL is because you're trying to overwrite an existing database, but did not specify to overwrite/replace the existing database. The following might work:
Use Master
Go
RESTORE DATABASE Publications
FROM DISK = 'C:\Publications_backup_2012_10_15_010004_5648316.bak'
WITH
MOVE 'Publications' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS2008R2\MSSQL\DATA\Publications.mdf',--adjust path
MOVE 'Publications_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS2008R2\MSSQL\DATA\Publications.ldf'
, REPLACE -- Add REPLACE to specify the existing database which should be overwritten.
I had this problem after changed project name. I used all the methods mentioned on the internet but still doesn't work. Then I realized that all the header files not found was from cocoapods, so I re-installed the cocoapods using pod install
, and thus solved the problem.
Hope this could help.

Have a same problem. My solution is after you handle with parsing arguments using argparse or other way, remove arguments from sys.argv
sys.argv = sys.argv[:1]
If you need you can filter unittest arguments from main.parseArgs()
Answer for PyCharm 2016.1 on OSX: (This is an update to the answer by @GeorgeWilliams993's answer above, but I don't have the rep yet to make comments.)
Go to Pycharm menu --> Preferences --> Project: (projectname) --> Project Interpreter
At the top is a popup for "Project Interpreter," and to the right of it is a button with ellipses (...) - click on this button for a different popup and choose "More" (or, as it turns out, click on the main popup and choose "Show All").
This shows a list of interpreters, with one selected. At the bottom of the screen are a set of tools... pick the rightmost one:
Now you should see all the paths pycharm is searching to find imports, and you can use the "+" button at the bottom to add a new path.
I think the most significant difference from @GeorgeWilliams993's answer is that the gear button has been replaced by a set of ellipses. That threw me off.
The arguments
object is where the functions arguments are stored.
The arguments object acts and looks like an array, it basically is, it just doesn't have the methods that arrays do, for example:
Array.forEach(callback[, thisArg]);
Array.map(callback[, thisArg])
Array.filter(callback[, thisArg]);
Array.indexOf(searchElement[, fromIndex])
I think the best way to convert a arguments
object to a real Array is like so:
argumentsArray = [].slice.apply(arguments);
That will make it an array;
reusable:
function ArgumentsToArray(args) {
return [].slice.apply(args);
}
(function() {
args = ArgumentsToArray(arguments);
args.forEach(function(value) {
console.log('value ===', value);
});
})('name', 1, {}, 'two', 3)
result:
>
value === name
>value === 1
>value === Object {}
>value === two
>value === 3
I like to use filter:
var id_tag = [1,2,3,78,5,6,7,8,47,34,90];
// delete where id_tag = 90
id_tag = id_tag.filter(function(x) {
if (x !== 90) {
return x;
}
});
Set alias: (based on the top answer)
git config --global alias.track-all-branches '!git fetch --all && for remote in `git branch -r`; do git branch --track ${remote#origin/} $remote; done && git fetch --all'
Now to track all the branches:
git track-all-branches
Don't use "new Date()", because it takes the input date string as local time:
new Date('11/08/2010').getTime()-new Date('11/07/2010').getTime(); //90000000
new Date('11/07/2010').getTime()-new Date('11/06/2010').getTime(); //86400000
we should use "NewDate()", it takes the input as GMT time:
function NewDate(str)
{str=str.split('-');
var date=new Date();
date.setUTCFullYear(str[0], str[1]-1, str[2]);
date.setUTCHours(0, 0, 0, 0);
return date;
}
NewDate('2010-11-07').toGMTString();
NewDate('2010-11-08').toGMTString();
Assuming dateTime1
and dateTime2
are DateTime
values:
var diffInSeconds = (dateTime1 - dateTime2).TotalSeconds;
In your case, you 'd use DateTime.Now
as one of the values and the time in the list as the other. Be careful of the order, as the result can be negative if dateTime1
is earlier than dateTime2
.
If you don't have access to the classes to change the properties, or don't want to always use the same rename property, renaming can also be done by creating a custom resolver.
For example, if you have a class called MyCustomObject
, that has a property called LongPropertyName
, you can use a custom resolver like this…
public class CustomDataContractResolver : DefaultContractResolver
{
public static readonly CustomDataContractResolver Instance = new CustomDataContractResolver ();
protected override JsonProperty CreateProperty(MemberInfo member, MemberSerialization memberSerialization)
{
var property = base.CreateProperty(member, memberSerialization);
if (property.DeclaringType == typeof(MyCustomObject))
{
if (property.PropertyName.Equals("LongPropertyName", StringComparison.OrdinalIgnoreCase))
{
property.PropertyName = "Short";
}
}
return property;
}
}
Then call for serialization and supply the resolver:
var result = JsonConvert.SerializeObject(myCustomObjectInstance,
new JsonSerializerSettings { ContractResolver = CustomDataContractResolver.Instance });
And the result will be shortened to {"Short":"prop value"} instead of {"LongPropertyName":"prop value"}

Solution in Android Java:
Start your EditText, the ID is come to your xml id.
EditText myText = (EditText)findViewById(R.id.my_text_id);
in your OnCreate Method, just set the text by the name defined.
String text = "here put the text that you want"
use setText method from your editText.
myText.setText(text); //variable from point 2
The recommended way is to use a Mutex. You can check out a sample here : http://www.codeproject.com/KB/cs/singleinstance.aspx
In specific the code:
///
/// check if given exe alread running or not
///
/// returns true if already running
private static bool IsAlreadyRunning()
{
string strLoc = Assembly.GetExecutingAssembly().Location;
FileSystemInfo fileInfo = new FileInfo(strLoc);
string sExeName = fileInfo.Name;
bool bCreatedNew;
Mutex mutex = new Mutex(true, "Global\\"+sExeName, out bCreatedNew);
if (bCreatedNew)
mutex.ReleaseMutex();
return !bCreatedNew;
}
use .any()
if numpy.isnan(myarray).any()
numpy.isfinite maybe better than isnan for checking
if not np.isfinite(prop).all()
To avoid placing HTML tags in the title attribute, another solution is to use markdown. For instance, you could use [br] to represent a line break, then perform a simple replace in the content function.
In title attribute:
"Sample Line 1[br][br]Sample Line 2"
In your content function:
content: function () {
return $(this).attr('title').replace(/\[br\]/g,"<br />");
}
In python:
('<MY_TOKEN>')
is equivalent to
'<MY_TOKEN>'
And requests interprets
('TOK', '<MY_TOKEN>')
As you wanting requests to use Basic Authentication and craft an authorization header like so:
'VE9LOjxNWV9UT0tFTj4K'
Which is the base64 representation of 'TOK:<MY_TOKEN>'
To pass your own header you pass in a dictionary like so:
r = requests.get('<MY_URI>', headers={'Authorization': 'TOK:<MY_TOKEN>'})
use coalesce
COALESCE(value [, ...])
The COALESCE function returns the first of its arguments that is not null. Null is returned only if all arguments are null. It is often used to substitute a default value for null values when data is retrieved for display.
Edit
Here's an example of COALESCE
with your query:
SELECT AVG( price )
FROM(
SELECT *, cume_dist() OVER ( ORDER BY price DESC ) FROM web_price_scan
WHERE listing_Type = 'AARM'
AND u_kbalikepartnumbers_id = 1000307
AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
AND COALESCE( price, 0 ) > ( SELECT AVG( COALESCE( price, 0 ) )* 0.50
FROM ( SELECT *, cume_dist() OVER ( ORDER BY price DESC )
FROM web_price_scan
WHERE listing_Type='AARM'
AND u_kbalikepartnumbers_id = 1000307
AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
) g
WHERE cume_dist < 0.50
)
AND COALESCE( price, 0 ) < ( SELECT AVG( COALESCE( price, 0 ) ) *2
FROM( SELECT *, cume_dist() OVER ( ORDER BY price desc )
FROM web_price_scan
WHERE listing_Type='AARM'
AND u_kbalikepartnumbers_id = 1000307
AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
) d
WHERE cume_dist < 0.50)
)s
HAVING COUNT(*) > 5
IMHO COALESCE
should not be use with AVG
because it modifies the value. NULL
means unknown and nothing else. It's not like using it in SUM
. In this example, if we replace AVG
by SUM
, the result is not distorted. Adding 0 to a sum doesn't hurt anyone but calculating an average with 0 for the unknown values, you don't get the real average.
In that case, I would add price IS NOT NULL
in WHERE
clause to avoid these unknown values.
Why could you not just do something like this?
class Foo {
constructor(myObj){
Object.assign(this, myObj);
}
get name() { return this._name; }
set name(v) { this._name = v; }
}
let foo = new Foo({ name: "bat" });
foo.toJSON() //=> your json ...
