If you use management studio, simply select the wardNo, BHTNo, testID columns and click on the key mark in the toolbar.
Command for this is,
ALTER TABLE dbo.testRequest
ADD CONSTRAINT PK_TestRequest
PRIMARY KEY (wardNo, BHTNo, TestID)
I think you are looking for this function:
http://doc.qt.io/qt-5/qdatetime.html#toTime_t
uint QDateTime::toTime_t () const
Returns the datetime as the number of seconds that have passed since 1970-01-01T00:00:00, > Coordinated Universal Time (Qt::UTC).
On systems that do not support time zones, this function will behave as if local time were Qt::UTC.
See also setTime_t().
In Ubuntu/Mint (Debian based)
$ sudo apt-get install php5-gd
Prefix the call with Module2 (ex. Module2.IDLE
). I'm assuming since you asked this that you have IDLE defined multiple times in the project, otherwise this shouldn't be necessary.
You can call up the color picker from any Cocoa application (TextEdit, Mail, Keynote, Pages, etc.) by hitting Shift-Command-C
The following article explains more about using Mac OS's Color Picker.
http://www.macworld.com/article/46746/2005/09/colorpickersecrets.html
I think the problem may be that you are not finding your element because of the "#" in your call to get it:
window.parent.document.getElementById('#target');
You only need the # if you are using jquery. Here it should be:
window.parent.document.getElementById('target');
Actually you get promise
on $http.get
.
Try to use followed flow:
<li ng-repeat="document in documents" ng-class="IsFiltered(document.Filtered)">
<span><input type="checkbox" name="docChecked" id="doc_{{document.Id}}" ng-model="document.Filtered" /></span>
<span>{{document.Name}}</span>
</li>
Where documents
is your array.
$scope.documents = [];
$http.get('/Documents/DocumentsList/' + caseId).then(function(result) {
result.data.forEach(function(val, i) {
$scope.documents.push(/* put data here*/);
});
}, function(error) {
alert(error.message);
});
Similar to some answers here, but if you want to find duplicates based on some property:
public static <T, R> Set<R> findDuplicates(Collection<? extends T> collection, Function<? super T, ? extends R> mapper) {
Set<R> uniques = new HashSet<>();
return collection.stream()
.map(mapper)
.filter(e -> !uniques.add(e))
.collect(toSet());
}
LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.text_entry, null);
//text_entry is an Layout XML file containing two text field to display in alert dialog
final EditText input1 = (EditText) textEntryView.findViewById(R.id.EditText1);
final EditText input2 = (EditText) textEntryView.findViewById(R.id.EditText2);
input1.setText("DefaultValue", TextView.BufferType.EDITABLE);
input2.setText("DefaultValue", TextView.BufferType.EDITABLE);
final AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setIcon(R.drawable.icon)
.setTitle("Enter the Text:")
.setView(textEntryView)
.setPositiveButton("Save",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
Log.i("AlertDialog","TextEntry 1 Entered "+input1.getText().toString());
Log.i("AlertDialog","TextEntry 2 Entered "+input2.getText().toString());
/* User clicked OK so do some stuff */
}
})
.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int whichButton) {
}
});
alert.show();
As You're getting values from textfield as jTextField3.getText();
.
As it is a textField
it will return you string format as its format says:
String getText()
Returns the text contained in this TextComponent.
So, convert your String
to Integer
as:
int jml = Integer.parseInt(jTextField3.getText());
instead of directly setting
int jml = jTextField3.getText();
String.split()
can also accept a regular expression:
input.split(/[ ,]+/);
This particular regex splits on a sequence of one or more commas or spaces, so that e.g. multiple consecutive spaces or a comma+space sequence do not produce empty elements in the results.
I would use to table header tag below for a text in a table to make it standout from the rest of the table content.
<table>
<tr>
<th>Dimension:</th>
<td>98cm x 71cm</td>
</tr>
</table
What types of files is not mentioned. If they're media files, go ahead with flat files. You probably just need a DB for tags and some way to associate the "external BLOBs" to the records in the DB. But if full text search is something you need, there's no other way to go but migrate to a full DB.
Another thing, your filesystem might provide the ceiling as far as number of physical files are concerned.
In separate terminal windows do the following:
Start the broker:
mosquitto
Start the command line subscriber:
mosquitto_sub -v -t 'test/topic'
Publish test message with the command line publisher:
mosquitto_pub -t 'test/topic' -m 'helloWorld'
As well as seeing both the subscriber and publisher connection messages in the broker terminal the following should be printed in the subscriber terminal:
test/topic helloWorld
The short answer is that setting grid-auto-rows: 1fr;
on the grid container solves what was asked.
I resolved this problem by navigating to C:\Python27\Scripts folder and then run file.py file instead of C:\Python27 folder
There isn’t really an ideal conversion, but I would like to supply a couple of options.
java.time
First, you should use LocalDate
from java.time, the modern Java date and time API, for parsing and holding your date. Avoid Date
and SimpleDateFormat
since they have design problems and also are long outdated. The latter in particular is notoriously troublesome.
DateTimeFormatter originalDateFormatter = DateTimeFormatter.ofPattern("dd/MM/uuuu");
String dateString = "13/06/1983";
LocalDate date = LocalDate.parse(dateString, originalDateFormatter);
System.out.println(date);
The output is:
1983-06-13
Do you need to go any further? LocalDate.toString()
produces the format you asked about.
Format and parse
Assuming that you do require an XMLGregorianCalendar
the first and easy option for converting is:
XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance()
.newXMLGregorianCalendar(date.toString());
System.out.println(xmlDate);
1983-06-13
Formatting to a string and parsing it back feels like a waste to me, but as I said, it’s easy and I don’t think that there are any surprises about the result being as expected.
Pass year, month and day of month individually
XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance()
.newXMLGregorianCalendarDate(date.getYear(), date.getMonthValue(),
date.getDayOfMonth(), DatatypeConstants.FIELD_UNDEFINED);
The result is the same as before. We need to make explicit that we don’t want a time zone offset (this is what DatatypeConstants.FIELD_UNDEFINED
specifies). In case someone is wondering, both LocalDate
and XMLGregorianCalendar
number months the way humans do, so there is no adding or subtracting 1.
Convert through GregorianCalendar
I only show you this option because I somehow consider it the official way: convert LocalDate
to ZonedDateTime
, then to GregorianCalendar
and finally to XMLGregorianCalendar
.
ZonedDateTime dateTime = date.atStartOfDay(ZoneOffset.UTC);
GregorianCalendar gregCal = GregorianCalendar.from(dateTime);
XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance()
.newXMLGregorianCalendar(gregCal);
xmlDate.setTime(DatatypeConstants.FIELD_UNDEFINED, DatatypeConstants.FIELD_UNDEFINED,
DatatypeConstants.FIELD_UNDEFINED, DatatypeConstants.FIELD_UNDEFINED);
xmlDate.setTimezone(DatatypeConstants.FIELD_UNDEFINED);
I like the conversion itself since we neither need to use strings nor need to pass individual fields (with care to do it in the right order). What I don’t like is that we have to pass a time of day and a time zone offset and then wipe out those fields manually afterwards.
You can use these solutions :
CSS rules applies to all tags that have following two classes :
.left.ui-class-selector {
/*style here*/
}
CSS rules applies to all tags that have <li>
with following two classes :
li.left.ui-class-selector {
/*style here*/
}
jQuery solution :
$("li.left.ui-class-selector").css("color", "red");
Javascript solution :
document.querySelector("li.left.ui-class-selector").style.color = "red";
VBScript has no notion of throwing or catching exceptions, but the runtime provides a global Err object that contains the results of the last operation performed. You have to explicitly check whether the Err.Number property is non-zero after each operation.
On Error Resume Next
DoStep1
If Err.Number <> 0 Then
WScript.Echo "Error in DoStep1: " & Err.Description
Err.Clear
End If
DoStep2
If Err.Number <> 0 Then
WScript.Echo "Error in DoStop2:" & Err.Description
Err.Clear
End If
'If you no longer want to continue following an error after that block's completed,
'call this.
On Error Goto 0
The "On Error Goto [label]" syntax is supported by Visual Basic and Visual Basic for Applications (VBA), but VBScript doesn't support this language feature so you have to use On Error Resume Next as described above.
Heres an easy way to do find the keys of a given value:
clients = {
"yellow"=>{"client_id"=>"2178"},
"orange"=>{"client_id"=>"2180"},
"red"=>{"client_id"=>"2179"},
"blue"=>{"client_id"=>"2181"}
}
p clients.rassoc("client_id"=>"2180")
...and to find the value of a given key:
p clients.assoc("orange")
it will give you the key-value pair.
Putting the javascript at the top would seem neater, but functionally, its better to go after the HTML. That way, your javascript won't run and try to reference HTML elements before they are loaded. This sort of problem often only becomes apparent when you load the page over an actual internet connection, especially a slow one.
You could also try to dynamically load the javascript by adding a header element from other javascript code, although that only makes sense if you aren't using all of the code all the time.
You can do this with the access_token
:
$access_array = split("\|", $access_token);
$session_key = $access_array[1];
You can use that $session key
in the PHP SDK to generate a functional logout URL.
$logoutUrl = $facebook->getLogoutUrl(array('next' => $logoutUrl, 'session_key' => $session_key));
This ends the browser's facebook session.
If choosing between OAuth versions, go with OAuth 2.0.
OAuth bearer tokens should only be used with a secure transport.
OAuth bearer tokens are only as secure or insecure as the transport that encrypts the conversation. HTTPS takes care of protecting against replay attacks, so it isn't necessary for the bearer token to also guard against replay.
While it is true that if someone intercepts your bearer token they can impersonate you when calling the API, there are plenty of ways to mitigate that risk. If you give your tokens a long expiration period and expect your clients to store the tokens locally, you have a greater risk of tokens being intercepted and misused than if you give your tokens a short expiration, require clients to acquire new tokens for every session, and advise clients not to persist tokens.
If you need to secure payloads that pass through multiple participants, then you need something more than HTTPS/SSL, since HTTPS/SSL only encrypts one link of the graph. This is not a fault of OAuth.
Bearer tokens are easy to for clients to obtain, easy for clients to use for API calls and are widely used (with HTTPS) to secure public facing APIs from Google, Facebook, and many other services.

Prior to C++11, you cannot initialise an array using type[]. However the latest c++11 provides(unifies) the initialisation, so you can do it in this way:
string* pStr = new string[3] { "hi", "there"};
See http://www2.research.att.com/~bs/C++0xFAQ.html#uniform-init
You need convert list
to numpy array
and then reshape
:
df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
a b c
0 1 2 3
1 4 5 6
2 7 8 9
you can use localStorage for storing the json data:
the example is given below:-
let JSONDatas = [
{"id": "Open"},
{"id": "OpenNew", "label": "Open New"},
{"id": "ZoomIn", "label": "Zoom In"},
{"id": "ZoomOut", "label": "Zoom Out"},
{"id": "Find", "label": "Find..."},
{"id": "FindAgain", "label": "Find Again"},
{"id": "Copy"},
{"id": "CopyAgain", "label": "Copy Again"},
{"id": "CopySVG", "label": "Copy SVG"},
{"id": "ViewSVG", "label": "View SVG"}
]
localStorage.setItem("datas", JSON.stringify(JSONDatas));
let data = JSON.parse(localStorage.getItem("datas"));
console.log(data);
It's perfectly safe as long as you always access the values through the struct via the .
(dot) or ->
notation.
What's not safe is taking the pointer of unaligned data and then accessing it without taking that into account.
Also, even though each item in the struct is known to be unaligned, it's known to be unaligned in a particular way, so the struct as a whole must be aligned as the compiler expects or there'll be trouble (on some platforms, or in future if a new way is invented to optimise unaligned accesses).
The folder is part of the URL you set when you create request
: "ftp://www.contoso.com/test.htm"
. If you use "ftp://www.contoso.com/wibble/test.htm"
then the file will be uploaded to a folder named wibble
.
You may need to first use a request with Method = WebRequestMethods.Ftp.MakeDirectory
to make the wibble
folder if it doesn't already exist.
Hmm, I would suggest that you use Flyweight to implement the states. Purpose: Avoid the memory overhead of a large number of small objects. State machines can get very, very big.
http://en.wikipedia.org/wiki/Flyweight_pattern
I'm not sure that I see the need to use design pattern State to implement the nodes. The nodes in a state machine are stateless. They just match the current input symbol to the available transitions from the current state. That is, unless I have entirely forgotten how they work (which is a definite possiblilty).
If I were coding it, I would do something like this:
interface FsmNode {
public boolean canConsume(Symbol sym);
public FsmNode consume(Symbol sym);
// Other methods here to identify the state we are in
}
List<Symbol> input = getSymbols();
FsmNode current = getStartState();
for (final Symbol sym : input) {
if (!current.canConsume(sym)) {
throw new RuntimeException("FSM node " + current + " can't consume symbol " + sym);
}
current = current.consume(sym);
}
System.out.println("FSM consumed all input, end state is " + current);
What would Flyweight do in this case? Well, underneath the FsmNode there would probably be something like this:
Map<Integer, Map<Symbol, Integer>> fsm; // A state is an Integer, the transitions are from symbol to state number
FsmState makeState(int stateNum) {
return new FsmState() {
public FsmState consume(final Symbol sym) {
final Map<Symbol, Integer> transitions = fsm.get(stateNum);
if (transisions == null) {
throw new RuntimeException("Illegal state number " + stateNum);
}
final Integer nextState = transitions.get(sym); // May be null if no transition
return nextState;
}
public boolean canConsume(final Symbol sym) {
return consume(sym) != null;
}
}
}
This creates the State objects on a need-to-use basis, It allows you to use a much more efficient underlying mechanism to store the actual state machine. The one I use here (Map(Integer, Map(Symbol, Integer))) is not particulary efficient.
Note that the Wikipedia page focuses on the cases where many somewhat similar objects share the similar data, as is the case in the String implementation in Java. In my opinion, Flyweight is a tad more general, and covers any on-demand creation of objects with a short life span (use more CPU to save on a more efficient underlying data structure).
In kruskal Algorithm we have number of edges and number of vertices on a given graph but on each edge we have some value or weight on behalf of which we can prepare a new graph which must be not cyclic or not close from any side For Example
graph like this _____________ | | | | | | |__________| | Give name to any vertex a,b,c,d,e,f .
I've simply added
jQuery.browser = {
msie: false,
version: 0
};
after jquery script, because I don't care about IE anymore.
You could just change this:
`create_date` TIMESTAMP NOT NULL DEFAULT '0000-00-00 00:00:00',
To something like this:
`create_date` TIMESTAMP NOT NULL DEFAULT '2018-04-01 12:00:00',
Simple example :
package test;
public class UpperClass {
public static class StaticInnerClass {}
public class InnerClass {}
public static void main(String[] args) {
// works
StaticInnerClass stat = new StaticInnerClass();
// doesn't compile
InnerClass inner = new InnerClass();
}
}
If non-static the class cannot be instantiated exept in an instance of the upper class (so not in the example where main is a static function)
If you use the new querySelectorAll you can call forEach directly.
document.querySelectorAll('.edit').forEach(function(button) {
// Now do something with my button
});
Per the comment below. nodeLists do not have a forEach function.
If using this with babel you can add Array.from
and it will convert non node lists to a forEach array. Array.from
does not work natively in browsers below and including IE 11.
Array.from(document.querySelectorAll('.edit')).forEach(function(button) {
// Now do something with my button
});
At our meetup last night I discovered another way to handle node lists not having forEach
[...document.querySelectorAll('.edit')].forEach(function(button) {
// Now do something with my button
});

The "illegal instruction" message is simply telling you that your binaries contain instructions the version of the OS that you are attempting to run them under does not understand. I can't give you the precise meaning of 4

How does 64 bit code work on OS-X 10.5?
what does macosx-version-min imply?
I think it's pretty well covered by the answers above that String args[]
is simply an array of string arguments you can pass to your application when you run it. For completion, I might add that it's also valid to define the method parameter passed to the main
method as a variable argument (varargs) of type String:
public static void main (String... args)
In other words, the main
method must accept either a String array (String args[]
) or varargs (String... args
) as a method argument. And there is no magic with the name args
either. You might as well write arguments
or even freddiefujiwara
as shown in below e.gs.:
public static void main (String[] arguments)
public static void main (String[] freddiefujiwara)
It is a library from SSL. You need to install openssl.
You might also meet missing readline()
function in python. You have to install pyreadline Lib.
Seems like you have your path right. But what is your working directory? on command prompt run:
javac -version
this should show your java version. if it doesnt, you have not set java in path correctly.
navigate to C:
cd \
Then:
javac -sourcepath users\AccName\Desktop -d users\AccName\Desktop first.java
-sourcepath is the complete path to your .java file, -d is the path/directory you want your .class files to be, then finally the file you want compiled (first.java).

In addition to some of the other answers, you could also access the HTML element via:
var htmlEl = document.body.parentNode;
Then you could get the inner HTML content:
var inner = htmlEl.innerHTML;
Doing so this way seems to be marginally faster. If you are just obtaining the HTML element, however, document.body.parentNode
seems to be quite a bit faster.
After you have the HTML element, you can mess with the attributes with the getAttribute
and setAttribute
methods.
For the DOCTYPE, you could use document.doctype
, which was elaborated upon in this question.
Could it be that you're using a NumPy array? Python has the array module, but that does not support multi-dimensional arrays. Normal Python lists are single-dimensional too.
However, if you have a simple two-dimensional list like this:
A = [[1,2,3,4],
[5,6,7,8]]
then you can extract a column like this:
def column(matrix, i):
return [row[i] for row in matrix]
Extracting the second column (index 1):
>>> column(A, 1)
[2, 6]
Or alternatively, simply:
>>> [row[1] for row in A]
[2, 6]
Arrays.asList() -> then calling the contains() method will always work, but a search algorithm is much better since you don't need to create a lightweight list wrapper around the array, which is what Arrays.asList() does.
public boolean findString(String[] strings, String desired){
for (String str : strings){
if (desired.equals(str)) {
return true;
}
}
return false; //if we get here… there is no desired String, return false.
}
If you want "To get all tables only", Then use this query:
SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME like '%'
and TABLE_SCHEMA = 'tresbu_lk'
If you want "To get all tables with Columns", Then use this query:
SELECT DISTINCT TABLE_NAME, COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE column_name LIKE '%'
AND TABLE_SCHEMA='tresbu_lk'
If you want to input more data into the form, you simply access the submitted data through $_POST.
If you have
<input type="text" name="firstname" />
you access it with
$firstname = $_POST["firstname"];
You could then update your query line to read
mysql_query("INSERT INTO dbProfiles (photo,firstname)
VALUES('{$filename}','{$firstname}')");
Note: Always filter and sanitize your data.
This is a two-step process:
you need to create a login to SQL Server for that user, based on its Windows account
CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
you need to grant this login permission to access a database:
USE (your database)
CREATE USER (username) FOR LOGIN (your login name)
Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader
database role to read all tables.
USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'
The typical pattern would be as follows, but you need to actually define how the ordering should be applied (since a table is, by definition, an unordered bag of rows):
SELECT t.A, t.B, t.C, number = ROW_NUMBER() OVER (ORDER BY t.A)
FROM dbo.tableZ AS t
ORDER BY t.A;

Trello.com Trello is free for unlimited users. Period.
You almost definitely don't need "Sub-cards". Use the checklists instead, or if you REALLY need sub-cards, don't have a parent sub-card. Just name the tickets something like "Epic - Story A" or "Story - task Z" or whatever.
Another idea is to create two boards (did I mention you can have unlimited boards for free too?). One for your epics and one for your stories. Call one your product management board and the other your sprint board, or whatever you like.
I'm not sure what you need different roles for - but, people aren't crazy - they know their job. As a startup if you already have problems getting people to not do crazy things (Where you need to restrict their permissions) you have much much bigger issues.
The point is that you need a SMALL tool to help you track stuff. Not a super rigid tool that makes you work in a super specific way. As a new (I assume?) startup, you should let your process grow into a tool. Don't beef up your process to fit a tool.

I really think your going about this in the wrong manner. Trying to download and parse a +3Mb text file is complete insanity. Why not parse the file on the server side, storing the results viva an ORM to a database(your choice, SQL is good but it also depends on the content key-value data works better on something like CouchDB) then use ajax to parse data on the client end.
Plus, an even better idea would to skip the text file entirely for even better performance if at all possible.

No. Extension methods require an instance variable (value) for an object. You can however, write a static wrapper around the ConfigurationManager
interface. If you implement the wrapper, you don't need an extension method since you can just add the method directly.
public static class ConfigurationManagerWrapper
{
public static ConfigurationSection GetSection( string name )
{
return ConfigurationManager.GetSection( name );
}
.....
public static ConfigurationSection GetWidgetSection()
{
return GetSection( "widgets" );
}
}

In my case I needed to remove a query param of the url to prevent user to see it.
I found replaceState
safer than location.go because the path with the old query params disappeared of the stack and user can be redo the query related with this query. So, I prefer it to do it:
this.location.replaceState(this.router.url.split('?')[0]);
Whit location.go
, go to back with the browser will return to your old path with the query params and will keep it in the navigation stack.
this.location.go(this.router.url.split('?')[0]);

Unfortunately an ajax request gets the entire file, but you can filter the content once it's retrieved:
$.ajax({
url:href,
type:'GET',
success: function(data) {
var content = $('<div>').append(data).find('#content');
$('#content').html( content );
}
});
Note the use of a dummy element as find()
only works with descendants, and won't find root elements.
or let jQuery filter it for you:
$('#content').load(href + ' #IDofDivToFind');
I'm assuming this isn't a cross domain request, as that won't work, only pages on the same domain.
I had a similar problem that I am facing where I need to store live candlesticks from an event source limited to x items. I could have them stored in an object where the timestamp of each candle would act as the key and the candle itself would act as the value. Another possibility was that I could store it in an array where each item was the candle itself. One problem about live candles is that they keep sending updates on the same timestamp where the latest update holds the most recent data therefore you either update an existing item or add a new one. So here is a nice benchmark that attempts to combine all 3 possibilities. Arrays in the solution below are atleast 4x faster on average. Feel free to play
"use strict";
const EventEmitter = require("events");
let candleEmitter = new EventEmitter();
//Change this to set how fast the setInterval should run
const frequency = 1;
setInterval(() => {
// Take the current timestamp and round it down to the nearest second
let time = Math.floor(Date.now() / 1000) * 1000;
let open = Math.random();
let high = Math.random();
let low = Math.random();
let close = Math.random();
let baseVolume = Math.random();
let quoteVolume = Math.random();
//Clear the console everytime before printing fresh values
console.clear()
candleEmitter.emit("candle", {
symbol: "ABC:DEF",
time: time,
open: open,

It looks like Angular has support for this now.
From the latest (v1.2.0) docs for $routeProvider.when(path, route)
:
path
can contain optional named groups with a question mark (:name?
)
If your error event handler takes the three arguments (xmlhttprequest, textstatus, and message) when a timeout happens, the status arg will be 'timeout'.
Per the jQuery documentation:
Possible values for the second argument (besides null) are "timeout", "error", "notmodified" and "parsererror".
You can handle your error accordingly then.
I created this fiddle that demonstrates this.
$.ajax({
url: "/ajax_json_echo/",
type: "GET",
dataType: "json",
timeout: 1000,
success: function(response) { alert(response); },
error: function(xmlhttprequest, textstatus, message) {
if(textstatus==="timeout") {
alert("got timeout");
} else {
alert(textstatus);
}
}
});?
With jsFiddle, you can test ajax calls -- it will wait 2 seconds before responding. I put the timeout setting at 1 second, so it should error out and pass back a textstatus of 'timeout' to the error handler.
Hope this helps!
You should put it into command line in windows.
mysqladmin -u [username] -p flush-hosts
**** [MySQL password]
or
mysqladmin flush-hosts -u [username] -p
**** [MySQL password]
For network login use the following command:
mysqladmin -h <RDS ENDPOINT URL> -P <PORT> -u <USER> -p flush-hosts
mysqladmin -h [YOUR RDS END POINT URL] -P 3306 -u [DB USER] -p flush-hosts
you can permanently solution your problem by editing my.ini file[Mysql configuration file] change variables max_connections = 10000;
or
login into MySQL using command line -
mysql -u [username] -p
**** [MySQL password]
put the below command into MySQL window
SET GLOBAL max_connect_errors=10000;
set global max_connections = 200;
check veritable using command-
show variables like "max_connections";
show variables like "max_connect_errors";

Well, no. Why there should be? Just discard the string if you don't need it anymore.
&str
is more useful than String
when you need to only read a string, because it is only a view into the original piece of data, not its owner. You can pass it around more easily than String
, and it is copyable, so it is not consumed by the invoked methods. In this regard it is more general: if you have a String
, you can pass it to where an &str
is expected, but if you have &str
, you can only pass it to functions expecting String
if you make a new allocation.
You can find more on the differences between these two and when to use them in the official strings guide.
I often find that I only need to strip out comments and script elements. This has worked reliably for me for 15 years and can easily be extended to handle any element name in HTML or XML:
// delete all comments
response = response.replaceAll("<!--[^>]*-->", "");
// delete all script elements
response = response.replaceAll("<(script|SCRIPT)[^+]*?>[^>]*?<(/script|SCRIPT)>", "");
What I usually do is supply the path to the executable explicitly:
EXE=./bin/
...
test all:
$(EXE)x
I also use this technique to run non-native binaries under an emulator like QEMU if I'm cross compiling:
EXE = qemu-mips ./bin/
If make is using the sh shell, this should work:
test all:
PATH=bin:$PATH x
First, you'll need to store your initial state when using the componentWillMount()
function from the component lifecycle:
componentWillMount() {
this.initialState = this.state
}
This stores your initial state and can be used to reset the state whenever you need by calling
this.setState(this.initialState)
The answer of ADTC works fine, but I've find another solution, so I post it here if someone wants something different.
I think ADTC's solution is better, but mine's also works.
Here is the other solution I found
select p.name
from person p
where instr(p.name,chr(8211)) > 0; --contains the character chr(8211)
--at least 1 time
Thank you.
The @japf answer above is working fine and in my case I wanted to change the mouse cursor from a Spinning Wheel back to the normal Arrow once the CEF Browser finished loading the page. In case it can help someone, here is the code:
private void Browser_LoadingStateChanged(object sender, CefSharp.LoadingStateChangedEventArgs e) {
if (!e.IsLoading) {
// set the cursor back to arrow
Application.Current.Dispatcher.BeginInvoke(DispatcherPriority.Background,
new Action(() => Mouse.OverrideCursor = Cursors.Arrow));
}
}
2.0 COMPATIBLE SOLUTION:
Execute the below commands in Terminal (Linux/MacOS) or in Command Prompt (Windows) to install Tensorflow 2.0 using Bazel:
git clone https://github.com/tensorflow/tensorflow.git
cd tensorflow
#The repo defaults to the master development branch. You can also checkout a release branch to build:
git checkout r2.0
#Configure the Build => Use the Below line for Windows Machine
python ./configure.py
#Configure the Build => Use the Below line for Linux/MacOS Machine
./configure
#This script prompts you for the location of TensorFlow dependencies and asks for additional build configuration options.
#Build Tensorflow package
#CPU support
bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package
#GPU support
bazel build --config=opt --config=cuda --define=no_tensorflow_py_deps=true //tensorflow/tools/pip_package:build_pip_package
One solution (though not very pretty) is to use Apache common List/Set mutation
import org.apache.commons.collections.list.SetUniqueList;
final List<Long> vertexes=SetUniqueList.setUniqueList(new LinkedList<>());
it is a list without duplicates
You could use toArray() to convert into an array of Objects followed by this method to convert the array of Objects into an array of Strings:
Object[] objectArray = lst.toArray();
String[] stringArray = Arrays.copyOf(objectArray, objectArray.length, String[].class);
Ctrl+Shift+F formats the selected line(s) or the whole source code if you haven't selected any line(s) as per the formatter specified in your Eclipse, while Ctrl+I gives proper indent to the selected line(s) or the current line if you haven't selected any line(s).
Workaround:
Compile as 2.1 without android:installLocation="preferExternal"
.
OK?
Compile as 2.2 including android:installLocation="preferExternal"
.
This will still install on SDK version less than 8 (the XML tag is ignored).
In my case, none of the code above with bundle-operate
works; Here is my decision (I don't know if it is proper code or not, but it works in my case):
public class DialogMessageType extends DialogFragment {
private static String bodyText;
public static DialogMessageType addSomeString(String temp){
DialogMessageType f = new DialogMessageType();
bodyText = temp;
return f;
};
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final String[] choiseArray = {"sms", "email"};
String title = "Send text via:";
final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(title).setItems(choiseArray, itemClickListener);
builder.setCancelable(true);
return builder.create();
}
DialogInterface.OnClickListener itemClickListener = new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
switch (which){
case 0:
prepareToSendCoordsViaSMS(bodyText);
dialog.dismiss();
break;
case 1:
prepareToSendCoordsViaEmail(bodyText);
dialog.dismiss();
break;
default:
break;
}
}
};
[...]
}
public class SendObjectActivity extends FragmentActivity {
[...]
DialogMessageType dialogMessageType = DialogMessageType.addSomeString(stringToSend);
dialogMessageType.show(getSupportFragmentManager(),"dialogMessageType");
[...]
}
You need the n
flag. To count words use:
:%s/\i\+/&/gn
and a particular word:
:%s/the/&/gn
See count-items
documentation section.
If you simply type in:
%s/pattern/pattern/g
then the status line will give you the number of matches in vi as well.
The dot itself is not an operator, .^
is.
The .^
is a pointwise¹ (i.e. element-wise) power, as .*
is the pointwise product.
.^
Array power.A.^B
is the matrix with elementsA(i,j)
to theB(i,j)
power. The sizes ofA
andB
must be the same or be compatible.
C.f.

When you switch orientations, Android will create a new View. You're probably getting crashes because your background thread is trying to change the state on the old one. (It may also be having trouble because your background thread isn't on the UI thread)
I'd suggest making that mHandler volatile and updating it when the orientation changes.
To do this manually, you'd need something like:
List<string> existing;
if (!myDic.TryGetValue(key, out existing)) {
existing = new List<string>();
myDic[key] = existing;
}
// At this point we know that "existing" refers to the relevant list in the
// dictionary, one way or another.
existing.Add(extraValue);
However, in many cases LINQ can make this trivial using ToLookup
. For example, consider a List<Person>
which you want to transform into a dictionary of "surname" to "first names for that surname". You could use:
var namesBySurname = people.ToLookup(person => person.Surname,
person => person.FirstName);
This means that you must declare strict mode by writing "use strict"
at the beginning of the file or the function to use block-scope declarations.
EX:
function test(){
"use strict";
let a = 1;
}
<div class="tabbable">
<ul class="nav nav-tabs">
<li class="active"><a href="#aaa" data-toggle="tab">AAA</a></li>
<li><a href="#bbb" data-toggle="tab">BBB</a></li>
<li><a href="#ccc" data-toggle="tab">CCC</a></li>
</ul>
<div class="tab-content" id="tabs">
<div class="tab-pane fade active in" id="aaa">...Content...</div>
<div class="tab-pane" id="bbb">...Content...</div>
<div class="tab-pane" id="ccc">...Content...</div>
</div>
</div>
Add active class to any li element you want to be active after page load. And also adding active class to content div is needed ,fade in classes are useful for a smooth transition.
The issue in the original question is that you are not capturing "page" event, to resolve this you need to add (page)='yourEventHandler($event)
' as an attribute in the md-paginator tag.

UILabel extension based on this answer for Swift 4 and above
extension UILabel {
func retrieveTextHeight () -> CGFloat {
let attributedText = NSAttributedString(string: self.text!, attributes: [NSFontAttributeName:self.font])
let rect = attributedText.boundingRect(with: CGSize(width: self.frame.size.width, height: CGFloat.greatestFiniteMagnitude), options: .usesLineFragmentOrigin, context: nil)
return ceil(rect.size.height)
}
}
Can be used like:
self.labelHeightConstraint.constant = self.label.retrieveTextHeight()
I would prefer the C++ size constraints over the C versions:
// Ignore to the end of file
cin.ignore(std::numeric_limits<std::streamsize>::max())
// Ignore to the end of line
cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n')
select into

create table new_table as select * from old_table
In eclipse help documentation, we can all icons information as follows. Common path for all eclipse versions except eclipse version:
a
is defined locally in the function, and can't be used outside the function. If you want to return a char
array from the function, you'll need to allocate it dynamically:
char *a = malloc(1000);
And at some point call free
on the returned pointer.
You should also see a warning at this line: char b = "blah";
: you're trying to assign a string literal to a char
.
When I were trying install librosa
package with pip
(pip install librosa
), this error were appeared:
ERROR: Cannot uninstall 'llvmlite'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
I tried to remove llvmlite
, but pip uninstall
could not remove it. So, I used capability of ignore
of pip
by this code:
pip install librosa --ignore-installed llvmlite
Indeed, you can use this rule for ignoring a package you don't want to consider:
pip install {package you want to install} --ignore-installed {installed package you don't want to consider}
For Docker version 18.09.0 I found that format flag won't be needed
docker rm $(docker stop $(docker ps -a -q -f ancestor=<image-name>))
Here is the question: Is it possible that I can set the default value without using attribute 'value'?
Nope: value
is the only way to set the default attribute.
Why don't you want to use it?
I was facing the same problem on Linux, what I did was to select all the content (ctrl-A) and then press ctrl+shift+L, It gives you a cursor on each line and then you can add similar content to each column.
Also you can perform other operations like cut, copy and paste column wise.
PS :- If you want to select a rectangular set of data from text, you can also press shift and hold Right Mouse button and then select data in a rectangular fashion. Then press CTRL+SHIFT+L to get the cursor on each line.
Use limitTo filter to display a limited number of results in ng-repeat.

What exactly is the structure of your HTML?
The previous CSS will work if the HTML is as such:
CSS
.foo:nth-child(2)
HTML
<div>
<div class="foo"></div>
<div class="foo">Find me</div>
...
</div>
But if you have the following HTML it will not work.
<div>
<div class="other"></div>
<div class="foo"></div>
<div class="foo">Find me</div>
...
</div>
Simple put, there is no selector for the getting the index of the matches from the rest of the selector before it.
In short, no, you can't.
Long answer, extension methods are just syntactic sugar. IE:
If you have an extension method on string let's say:
public static string SomeStringExtension(this string s)
{
//whatever..
}
When you then call it:
myString.SomeStringExtension();
The compiler just turns it into:
ExtensionClass.SomeStringExtension(myString);
So as you can see, there's no way to do that for static methods.
And another thing just dawned on me: what would really be the point of being able to add static methods on existing classes? You can just have your own helper class that does the same thing, so what's really the benefit in being able to do:
Bool.Parse(..)
vs.
Helper.ParseBool(..);
Doesn't really bring much to the table...
Install .NET framework as below, it will work .NET version 4.5 as well.

Is too simple by using the Windows Explorer search inside the project folder. Done.
try something like
background: url(bgimage.jpg) no-repeat;
background-size: 100%;
Like this: ^[^0-9]+$
Explanation:
^
matches the beginning of the string[^...]
matches anything that isn't inside0-9
means any character between 0 and 9+
matches one or more of the previous thing$
matches the end of the stringFor get value of tag selected:
$('#id_Of_Parent_Selected_Tag').find(":selected").val();
And if you want to get text use this code:
$('#id_Of_Parent_Selected_Tag').find(":selected").text();
For Example:
<div id="i_am_parent_of_select_tag">
<select>
<option value="1">CR7</option>
<option value="2">MESSI</option>
</select>
</div>
<script>
$('#i_am_parent_of_select_tag').find(":selected").val();//OUTPUT:1 OR 2
$('#i_am_parent_of_select_tag').find(":selected").text();//OUTPUT:CR7 OR MESSI
</script>
You can use the accept attribute along with the . It doesn't work in IE and Safari.
Depending on your project scale and extensibility, you could use Struts. Struts offers two ways to limit the uploaded file type, declaratively and programmatically.
For more information: http://struts.apache.org/2.0.14/docs/file-upload.html#FileUpload-FileTypes
$(document).ready(function () {
toggleFields(); // call this first so we start out with the correct visibility depending on the selected form values
// this will call our toggleFields function every time the selection value of our other field changes
$("#dbType").change(function () {
toggleFields();
});
});
// this toggles the visibility of other server
function toggleFields() {
if ($("#dbType").val() === "other")
$("#otherServer").show();
else
$("#otherServer").hide();
}
HTML:
<p>Choose type</p>
<p>Server:
<select id="dbType" name="dbType">
<option>Choose Database Type</option>
<option value="oracle">Oracle</option>
<option value="mssql">MS SQL</option>
<option value="mysql">MySQL</option>
<option value="other">Other</option>
</select>
</p>
<div id="otherServer">
<p>Server:
<input type="text" name="server_name" />
</p>
<p>Port:
<input type="text" name="port_no" />
</p>
</div>
<p align="center">
<input type="submit" value="Submit!" />
</p>
If you change the classes and load the content within the same function you should be fine.
$(document).ready(function(){
$('.nav li').click(function(event){
//remove all pre-existing active classes
$('.active').removeClass('active');
//add the active class to the link we clicked
$(this).addClass('active');
//Load the content
//e.g.
//load the page that the link was pointing to
//$('#content').load($(this).find(a).attr('href'));
event.preventDefault();
});
});

isn't this the ternary operator?
var x= expression ? true:false
You can use a select into
statement. See more at W3Schools.

Bill Venners: In your blog post entitled "Why REST Failed," you said that we need all four HTTP verbs—GET, POST, PUT, and DELETE— and lamented that browser vendors only GET and POST." Why do we need all four verbs? Why aren't GET and POST enough?
Elliotte Rusty Harold: There are four basic methods in HTTP: GET, POST, PUT, and DELETE. GET is used most of the time. It is used for anything that's safe, that doesn't cause any side effects. GET is able to be bookmarked, cached, linked to, passed through a proxy server. It is a very powerful operation, a very useful operation.
POST by contrast is perhaps the most powerful operation. It can do anything. There are no limits as to what can happen, and as a result, you have to be very careful with it. You don't bookmark it. You don't cache it. You don't pre-fetch it. You don't do anything with a POST without asking the user. Do you want to do this? If the user presses the button, you can POST some content. But you're not going to look at all the buttons on a page, and start randomly pressing them. By contrast browsers might look at all the links on the page and pre-fetch them, or pre-fetch the ones they think are most likely to be followed next. And in fact some browsers and Firefox extensions and various other tools have tried to do that at one point or another.
PUT and DELETE are in the middle between GET and POST. The difference between PUT or DELETE and POST is that PUT and DELETE are *idempotent, whereas POST is not. PUT and DELETE can be repeated if necessary. Let's say you're trying to upload a new page to a site. Say you want to create a new page at http://www.example.com/foo.html, so you type your content and you PUT it at that URL. The server creates that page at that URL that you supply. Now, let's suppose for some reason your network connection goes down. You aren't sure, did the request get through or not? Maybe the network is slow. Maybe there was a proxy server problem. So it's perfectly OK to try it again, or again—as many times as you like. Because PUTTING the same document to the same URL ten times won't be any different than putting it once. The same is true for DELETE. You can DELETE something ten times, and that's the same as deleting it once.
By contrast, POST, may cause something different to happen each time. Imagine you are checking out of an online store by pressing the buy button. If you send that POST request again, you could end up buying everything in your cart a second time. If you send it again, you've bought it a third time. That's why browsers have to be very careful about repeating POST operations without explicit user consent, because POST may cause two things to happen if you do it twice, three things if you do it three times. With PUT and DELETE, there's a big difference between zero requests and one, but there's no difference between one request and ten.
Please visit the url for more details. http://www.artima.com/lejava/articles/why_put_and_delete.html
Update:
Idempotent methods An idempotent HTTP method is a HTTP method that can be called many times without different outcomes. It would not matter if the method is called only once, or ten times over. The result should be the same. Again, this only applies to the result, not the resource itself. This still can be manipulated (like an update-timestamp, provided this information is not shared in the (current) resource representation.
Consider the following examples:
a = 4;
a++;
The first example is idempotent: no matter how many times we execute this statement, a will always be 4. The second example is not idempotent. Executing this 10 times will result in a different outcome as when running 5 times. Since both examples are changing the value of a, both are non-safe methods.
As far as I can tell what you could do is "retire" your previous app and redirect all users to your new app. This procedure is not supported by Google (tsk... tsk...), but it could be implemented in four steps:
Change the current application to show a message to the users about the upgrade and redirect them to the new app listing. Probably a full screen message would do with some friendly text. This message could be triggered remotely ideally, but a cut-off date can be used too. (But then that will be a hard deadline for you, so be careful... ;))
Release the modified old app as an upgrade, maybe with some feature upgrades/bug fixes too, to "sweeten the deal" to the users. Still there is no guarantee that all users will upgrade, but probably the majority will do.
Prepare your new app with the updated package name and upload it to the store, then trigger the message in the old app (or just wait until it expires, if that was your choice).
Unpublish the old app in Play Store to avoid any new installs. Unpublishing an app doesn't mean the users who already installed it won't have access to it anymore, but at least the potential new users won't find it on the market.
Not ideal and can be annoying to the users, sometimes even impossible to implement due to the status/possibilities of the app. But since Google left us no choice this is the only way to migrate the users of the old apps to a "new" one (even if it is not really new). Not to mention that if you don't have access to the sources and code signing details for the old app then all you could do is hoping that he users will notice the new app...
If anybody figured out a better way by all means: please do tell.

@jamylak answer is quite nice, however if you don't want to import a couple of modules just to do this simple task, write your own lambda

>>> L = [0, 23, 234, 89, None, 0, 35, 9]
>>> filter(lambda v: v is not None, L)
[0, 23, 234, 89, 0, 35, 9]
join()
means waiting for a thread to complete. This is a blocker method. Your main thread (the one that does the join()
) will wait on the t1.join()
line until t1
finishes its work, and then will do the same for t2.join()
.
It's very similar to
char array[] = {'O', 'n', 'e', ' ', /*etc*/ ' ', 'm', 'u', 's', 'i', 'c', '\0'};
but gives you read-only memory.
For a discussion of the difference between a char[]
and a char *
, see comp.lang.c FAQ 1.32.
I solved, thanks. In case anyone's interested, bouncycastle did the trick, just took me some time due to lack of knowledge from on my side and documentation. This is the code:
var bytesToDecrypt = Convert.FromBase64String("la0Cz.....D43g=="); // string to decrypt, base64 encoded
AsymmetricCipherKeyPair keyPair;
using (var reader = File.OpenText(@"c:\myprivatekey.pem")) // file containing RSA PKCS1 private key
keyPair = (AsymmetricCipherKeyPair) new PemReader(reader).ReadObject();
var decryptEngine = new Pkcs1Encoding(new RsaEngine());
decryptEngine.Init(false, keyPair.Private);
var decrypted = Encoding.UTF8.GetString(decryptEngine.ProcessBlock(bytesToDecrypt, 0, bytesToDecrypt.Length));
This one work for me !! This ngFor so it dynamically anchor tag, You need to wait them render
HTML:
<div #ngForComments *ngFor="let cm of Comments">
<a id="Comment_{{cm.id}}" fragment="Comment_{{cm.id}}" (click)="jumpToId()">{{cm.namae}} Reply</a> Blah Blah
</div>
My ts file:
private fragment: string;
@ViewChildren('ngForComments') AnchorComments: QueryList<any>;
ngOnInit() {
this.route.fragment.subscribe(fragment => { this.fragment = fragment;
});
}
ngAfterViewInit() {
this.AnchorComments.changes.subscribe(t => {
this.ngForRendred();
})
}
ngForRendred() {
this.jumpToId()
}
jumpToId() {
let x = document.querySelector("#" + this.fragment);
console.log(x)
if (x){
x.scrollIntoView();
}
}
Don't forget to import that ViewChildren
, QueryList
etc.. and add some constructor ActivatedRoute
!!
What @VonC says is correct, but you can put the commands to set debug directly into VM
arguments on jBoss
Launch.
To do that, open jBoss
server inside Eclipse
, go to Open launch configuration and put this in VM
arguments textbox
:
vm args
You should assign string value to environment variable.
os.environ["DEBUSSY"] = "1"
If you want to read or print the environment variable just use
print os.environ["DEBUSSY"]
This changes will be effective only for the current process where it was assigned, it will no change the value permanently. The child processes will automatically inherit the environment of the parent process.
You need a semicolon after font-family: Arial, Helvetica, sans-serif
. This will make your updated code the following:
<!DOCTYPE>
<html>
<head>
<title>DIV Font</title>
<style>
.my_text
{
font-family: Arial, Helvetica, sans-serif;
font-size: 40px;
font-weight: bold;
}
</style>
</head>
<body>
<div class="my_text">some text</div>
</body>
</html>
This works for too the first 1000 numbers (Python 3). Beginner solution to the problem but a solution nonetheless...
first_nums = ["", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven", "twelve",
"thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen"]
tens = ["ten", "twenty", "thirty","forty","fifty", "sixty","seventy","eighty","ninety"]
for num in range(1,1001):
if num < 20:
print(first_nums[num])
elif num < 100 and num % 10 == 0:
print(tens[int(num/10 - 1)])
elif num < 1000 and num % 100 == 0:
print(first_nums[int(num/100)] + " hundred")
elif num == 1000:
print("one thousand")
elif num < 100 and num % 10 != 0:
print(tens[int(num//10 - 1)] + " " + first_nums[int(num%10)])
elif num < 1000:
if num%100 < 20:
print(first_nums[int(num//100)] + " hundred and " + first_nums[num%100])
else:
print(first_nums[int(num//100)] + " hundred and " + tens[int(num%100//10 - 1)] + " " + first_nums[int(num%10)])
I ended up on this page running Web Apps on Azure.
The page cannot be displayed because an internal server error has occurred.
We ran into this problem because we applicationInitialization in the web.config
<applicationInitialization
doAppInitAfterRestart="true"
skipManagedModules="true">
<add initializationPage="/default.aspx" hostName="myhost"/>
</applicationInitialization>
If running on Azure, have a look at site slots. You should warm up the pages on a staging slot before swapping it to the production slot.
ZIP is a file format used for storing an arbitrary number of files and folders together with lossless compression. It makes no strict assumptions about the compression methods used, but is most frequently used with DEFLATE.
Gzip is both a compression algorithm based on DEFLATE but less encumbered with potential patents et al, and a file format for storing a single compressed file. It supports compressing an arbitrary number of files and folders when combined with tar. The resulting file has an extension of .tgz
or .tar.gz
and is commonly called a tarball.
zlib is a library of functions encapsulating DEFLATE in its most common LZ77 incarnation.
My answer comes from here
You can make a derived class, which will set the timeout property of the base WebRequest
class:
using System;
using System.Net;
public class WebDownload : WebClient
{
/// <summary>
/// Time in milliseconds
/// </summary>
public int Timeout { get; set; }
public WebDownload() : this(60000) { }
public WebDownload(int timeout)
{
this.Timeout = timeout;
}
protected override WebRequest GetWebRequest(Uri address)
{
var request = base.GetWebRequest(address);
if (request != null)
{
request.Timeout = this.Timeout;
}
return request;
}
}
and you can use it just like the base WebClient class.
I think the question asker is (was) thinking that git bash is a command like git init or git checkout. Git bash is not a command, it is an interface. I will also assume the asker is not a linux user because bash is very popular the unix/linux world. The name "bash" is an acronym for "Bourne Again SHell". Bash is a text-only command interface that has features which allow automated scripts to be run. A good analogy would be to compare bash to the new PowerShell interface in Windows7/8. A poor analogy (but one likely to be more readily understood by more people) is the combination of the command prompt and .BAT (batch) command files from the days of DOS and early versions of Windows.
REFERENCES:
Besides all the excellent solutions offered here I would like to offer a different solution.
I'm not sure if you're free to add dependencies, but if you can, you could add the https://code.google.com/p/guava-libraries/ as a dependency. This library adds support for many basic functional operations to Java and can make working with collections a lot easier and more readable.
In the code I replaced the type of the List by T, since I don't know what your list is typed to.
This problem can with guava be solved like this:
List<T> filteredList = new Arraylist<>(filter(list, not(XXX_EQUAL_TO_AAA)));
And somewhere else you then define XXX_EQUAL_TO_AAA as:
public static final Predicate<T> XXX_EQUAL_TO_AAA = new Predicate<T>() {
@Override
public boolean apply(T input) {
return input.getXXX().equalsIgnoreCase("AAA");
}
}
However, this is probably overkill in your situation. It's just something that becomes increasingly powerful the more you work with collections.
Ohw, also, you need these static imports:
import static com.google.common.base.Predicates.not;
import static com.google.common.collect.Collections2.filter;
I've just implemented and test this successfully. Same situation with my project, want to connect to a Raspberry Pi with no router or wifi. Just a simple ethernet cable.
Using ssh putty program put the address as
raspberrypi.local
Log and in and you can access the terminal.
Alternatively if VNC server is setup, use VNC server and put
raspberrypi.local:1
In the server address. input your VNC server password and you've now got GUI access to do what you want.
In may case it was run scripts in a remote location. In the posters situation, safely shutdown the Pi. Simples Pimples.
The Maven profile and the Spring profile are two completely different things. Your pom.xml defines spring.profiles.active
variable which is available in the build process, but not at runtime. That is why only the default profile is activated.
How to bind Maven profile with Spring?
You need to pass the build variable to your application so that it is available when it is started.
Define a placeholder in your application.properties
:
[email protected]@
The @spring.profiles.active@
variable must match the declared property from the Maven profile.
Enable resource filtering in you pom.xml:
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
</resource>
</resources>
…
</build>
When the build is executed, all files in the src/main/resources
directory will be processed by Maven and the placeholder in your application.properties
will be replaced with the variable you defined in your Maven profile.
For more details you can go to my post where I described this use case.
You could [potentially] do a rewrite of the URL, but yes: you have to have control of your DNS settings so that when a user is added it gets its own subdomain.
Named instances?
URL: jdbc:sqlserver://[serverName][\instanceName][:portNumber][;property=value]
Note: backward slash
The best way to do this is by running the command:
git diff --name-only --cached
When you check the manual you will likely find the following:
--name-only
Show only names of changed files.
And on the example part of the manual:
git diff --cached
Changes between the index and your current HEAD.
Combined together you get the changes between the index and your current HEAD
and Show only names of changed files.
Update: --staged
is also available as an alias for --cached
above in more recent git versions.
You can also use includes
const isApple = ['iPhone', 'iPad', 'iPod', 'iPad Simulator', 'iPhone Simulator', 'iPod Simulator',].includes(navigator.platform)
using std::string;
string string_replace( string src, string const& target, string const& repl)
{
// handle error situations/trivial cases
if (target.length() == 0) {
// searching for a match to the empty string will result in
// an infinite loop
// it might make sense to throw an exception for this case
return src;
}
if (src.length() == 0) {
return src; // nothing to match against
}
size_t idx = 0;
for (;;) {
idx = src.find( target, idx);
if (idx == string::npos) break;
src.replace( idx, target.length(), repl);
idx += repl.length();
}
return src;
}
Since it's not a member of the string
class, it doesn't allow quite as nice a syntax as in your example, but the following will do the equivalent:
test = string_replace( string_replace( test, "abc", "hij"), "def", "klm")
I had this problem recently. I stumbled across an option: default_authentication_plugin
For some reason it had set it to caching_sha2_password
, but updating the value to mysql_native_password
fixed it for me. I'm not sure what the differences are, though, so be careful!
Hope this helps someone!
Just adding 1 more scenario which may give the same error:
If you try to assign values to multiple variables, then also you will receive same error. For e.g.
In C (and many other languages), this is possible:
int a=2, b=3;
In Python:
a=2, b=5
will give error:
can't assign to literal
EDIT:
As per Arne's comment below, you can do this in Python for single line assignments in a slightly different way:
a, b = 2, 5
charAt
gets a character from a string, and you can switch on them since char
is an integer type.
So to switch on the first char
in the String
hello
,
switch (hello.charAt(0)) {
case 'a': ... break;
}
You should be aware though that Java char
s do not correspond one-to-one with code-points. See codePointAt
for a way to reliably get a single Unicode codepoints.
No, that is not a valid production according to the "credentials" definition in RFC 2617. You give a valid auth-scheme, but auth-param values must be of the form token "=" ( token | quoted-string )
(see section 1.2), and your example doesn't use "=" that way.
If you have LWP installed, it provides a binary simply named "GET".
$ GET http://example.com <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <HTML> <HEAD> <META http-equiv="Content-Type" content="text/html; charset=utf-8"> <TITLE>Example Web Page</TITLE> </HEAD> <body> <p>You have reached this web page by typing "example.com", "example.net","example.org" or "example.edu" into your web browser.</p> <p>These domain names are reserved for use in documentation and are not available for registration.

wget -O-

behave similarly.
If someone has to steal your code, it likely means your business model is not working. What do I mean by that? For example, I buy your product and then I ask for support. You're too busy or believe my request is not valid and a waste of your time. I decode your product in order to support my relative business. Your product becomes more valuable to me and I prioritize my time in a way to resolve the business model for leveraging your product. I recode and re-brand your product and then go out and make the money that you decided to leave on the table. There are reasons for protecting code, but most likely you are looking at the problem from the wrong perspective. Of course you are. You're the "coder", and I'm the business man. ;-) Cheers!
ps. I'm also a developer. i.e. "coder"
Just close (stop) and open (start) the database. This solved my problem.
You could run it without the -jar
command line argument if you happen to know the name of the main class you wish to run:
java -classpath .;myjar.jar;lib/referenced-class.jar my.package.MainClass
If perchance you are using linux, you should use ":" instead of ";" in the classpath.
Dan, no need to use fancy tricks. All you need to do is make copy of arr1 by doing this.
var arr2 = new Array(arr1);
_x000D_
Now arr1
and arr2
are two different array variables stored in separate stacks.
Check this out on jsfiddle.
As mentionned in comments, this is the updated solution in favor of Icon object with documentation.
Use Icon object
var icon = {
url: "../res/sit_marron.png", // url
scaledSize: new google.maps.Size(50, 50), // scaled size
origin: new google.maps.Point(0,0), // origin
anchor: new google.maps.Point(0, 0) // anchor
};
posicion = new google.maps.LatLng(latitud,longitud)
marker = new google.maps.Marker({
position: posicion,
map: map,
icon: icon
});
As Henrik wrote you can use dblink to connect remote database and fetch result. For example:
psql dbtest
CREATE TABLE tblB (id serial, time integer);
INSERT INTO tblB (time) VALUES (5000), (2000);
psql postgres
CREATE TABLE tblA (id serial, time integer);
INSERT INTO tblA
SELECT id, time
FROM dblink('dbname=dbtest', 'SELECT id, time FROM tblB')
AS t(id integer, time integer)
WHERE time > 1000;
TABLE tblA;
id | time
----+------
1 | 5000
2 | 2000
(2 rows)
PostgreSQL has record pseudo-type (only for function's argument or result type), which allows you query data from another (unknown) table.
Edit:
You can make it as prepared statement if you want and it works as well:
PREPARE migrate_data (integer) AS
INSERT INTO tblA
SELECT id, time
FROM dblink('dbname=dbtest', 'SELECT id, time FROM tblB')
AS t(id integer, time integer)
WHERE time > $1;
EXECUTE migrate_data(1000);
-- DEALLOCATE migrate_data;
Edit (yeah, another):
I just saw your revised question (closed as duplicate, or just very similar to this).
If my understanding is correct (postgres has tbla and dbtest has tblb and you want remote insert with local select, not remote select with local insert as above):
psql dbtest
SELECT dblink_exec
(
'dbname=postgres',
'INSERT INTO tbla
SELECT id, time
FROM dblink
(
''dbname=dbtest'',
''SELECT id, time FROM tblb''
)
AS t(id integer, time integer)
WHERE time > 1000;'
);
I don't like that nested dblink, but AFAIK I can't reference to tblB in dblink_exec body. Use LIMIT to specify top 20 rows, but I think you need to sort them using ORDER BY clause first.
If your batch file is not interactive and you don't need to see it run then this should work.
@echo off
call file.bat >textfile.txt 2>&1
Otherwise use a tee
filter. There are many, some not NT compatible. SFK the Swiss Army Knife has a tee feature and is still being developed. Maybe that will work for you.
Old post but as you said "why is it not using the correct certificate" I would like to offer an way to find out which SSL certificate is used for SMTP (see here) which required openssl:
openssl s_client -connect exchange01.int.contoso.com:25 -starttls smtp
This will outline the used SSL certificate for the SMTP service. Based on what you see here you can replace the wrong certificate (like you already did) with a correct one (or trust the certificate manually).
you can try this
class select_choice():
return x, y
a, b = test()

I installed MAMP and phpmyadmin was working.
But cannot find /usr/local/bin/mysql
This fixed it
sudo ln -s /Applications/MAMP/Library/bin/mysql /usr/local/bin/mysql
I have a similar problem (at least I think it is similar). In one of the replies here the solution is as follows:
select
A.*
from
table_A A
inner join table_B B
on A.id = B.id
where
B.tag = 'chair'
That WHERE clause I would like to be:
WHERE B.tag = A.<col_name>
or, in my specific case:
WHERE B.val BETWEEN A.val1 AND A.val2
More detailed:
Table A carries status information of a fleet of equipment. Each status record carries with it a start and stop time of that status. Table B carries regularly recorded, timestamped data about the equipment, which I want to extract for the duration of the period indicated in table A.
If you are using

Obviously not efficient but does the trick :)
Try:
$('body').on({

click: function() {
console.log("yeahhhh!!! but this doesn't work for me :(");
}

When using .on() and binding to a dynamic element, you need to refer to an element that already exists on the page (like body in the example). If you can use a more specific element that would improve performance.
Event handlers are bound only to the currently selected elements; they must exist on the page at the time your code makes the call to .on(). To ensure the elements are present and can be selected, perform event binding inside a document ready handler for elements that are in the HTML markup on the page. If new HTML is being injected into the page, select the elements and attach event handlers after the new HTML is placed into the page. Or, use delegated events to attach an event handler, as described next.
Here is code for List Of String:
int indexOfValue = myList.FindIndex(a => a.Contains("insert value from list"));
Here is Code for List Of Integer:
int indexOfNumber = myList.IndexOf(/*insert number from list*/);
You could use a negative look-ahead assertion:
^(?!tbd_).+
Or a negative look-behind assertion:
(^.{1,3}$|^.{4}(?<!tbd_).*)
Or just plain old character sets and alternations:
^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*
Go to the downloaded folder and there you find config.m4. Open the terminal and run phpsize.
This is an addition to dmd733's answer. I fixed the bug with Day duration (well I hope I did, haven't been able to test every case).
I also quickly added a String property to the result that holds the general time passed (sorry for the bad nested ifs!!). For example if used for UI and indicating when something was updated (like a RSS feed). Kind of out of place but nice-to-have:
function getTimeDiffAndPrettyText(oDatePublished) {
var oResult = {};
var oToday = new Date();
var nDiff = oToday.getTime() - oDatePublished.getTime();
// Get diff in days
oResult.days = Math.floor(nDiff / 1000 / 60 / 60 / 24);
nDiff -= oResult.days * 1000 * 60 * 60 * 24;
// Get diff in hours
oResult.hours = Math.floor(nDiff / 1000 / 60 / 60);
nDiff -= oResult.hours * 1000 * 60 * 60;
// Get diff in minutes
oResult.minutes = Math.floor(nDiff / 1000 / 60);
nDiff -= oResult.minutes * 1000 * 60;
// Get diff in seconds
oResult.seconds = Math.floor(nDiff / 1000);
// Render the diffs into friendly duration string
// Days
var sDays = '00';
if (oResult.days > 0) {
sDays = String(oResult.days);
}
if (sDays.length === 1) {
sDays = '0' + sDays;
}
// Format Hours
var sHour = '00';
if (oResult.hours > 0) {
sHour = String(oResult.hours);
}
if (sHour.length === 1) {
sHour = '0' + sHour;
}
// Format Minutes
var sMins = '00';
if (oResult.minutes > 0) {
sMins = String(oResult.minutes);
}
if (sMins.length === 1) {
sMins = '0' + sMins;
}
// Format Seconds
var sSecs = '00';
if (oResult.seconds > 0) {
sSecs = String(oResult.seconds);
}
if (sSecs.length === 1) {
sSecs = '0' + sSecs;
}
// Set Duration
var sDuration = sDays + ':' + sHour + ':' + sMins + ':' + sSecs;
oResult.duration = sDuration;
// Set friendly text for printing
if(oResult.days === 0) {
if(oResult.hours === 0) {
if(oResult.minutes === 0) {
var sSecHolder = oResult.seconds > 1 ? 'Seconds' : 'Second';
oResult.friendlyNiceText = oResult.seconds + ' ' + sSecHolder + ' ago';
} else {
var sMinutesHolder = oResult.minutes > 1 ? 'Minutes' : 'Minute';
oResult.friendlyNiceText = oResult.minutes + ' ' + sMinutesHolder + ' ago';
}

var sHourHolder = oResult.hours > 1 ? 'Hours' : 'Hour';
oResult.friendlyNiceText = oResult.hours + ' ' + sHourHolder + ' ago';
}
} else {
var sDayHolder = oResult.days > 1 ? 'Days' : 'Day';
oResult.friendlyNiceText = oResult.days + ' ' + sDayHolder + ' ago';
}
return oResult;

I used Mercury/32 and Pegasus Mail to get the mail() functional. It works great too as a mail server if you want an email address ending with your domain name.
You can include a project in more than one solution. I don't think a project has a concept of which solution it's part of. However, another alternative is to make the first solution build to some well-known place, and reference the compiled binaries. This has the disadvantage that you'll need to do a bit of work if you want to reference different versions based on whether you're building in release or debug configurations.
I don't believe you can make one solution actually depend on another, but you can perform your automated builds in an appropriate order via custom scripts. Basically treat your common library as if it were another third party dependency like NUnit etc.
Create your virtualenv with --no-site-packages
if you don't want it to be able to use external libraries:
virtualenv --no-site-packages my-virtualenv
. my-virtualenv/bin/activate
pip install ipython
Otherwise, as in your example, it can see a library installed in your system Python environment as satisfying your requested dependency.
You declare
int countlines(char *filename)
to take a char *
argument.
You call it like this
countlines(fp)
passing in a FILE *.
That is why you get that compile error.
You probably should change that second line to
countlines("Test.txt")
since you open the file in countlines
Your current code is attempting to open the file in two different places.
Thanks everyone, you all helped me learn a lot. This is what I came up with using some of your suggestions
#this is apparently a better way of getting multiple inputs at the same time than the
#way I was doing it
text = raw_input("please give 2 numbers to multiply separated with a comma:")
split_text = text.split(',')
numa = int(split_text[0])
numb = int(split_text[1])
#standing variables
total = 0
if numb > 0:
repeat = numb
else:
repeat = -numb
#for loops work better than while loops and are cheaper
#output the total
for count in range(repeat):
total += numa
#check to make sure the output is accurate
if numb < 0:
total = -total
print total
Thanks for all the help everyone.
Not sure if any of these help, but this might get you started: http://studiostyles.info
I know that the site owner has been gradually adding functionality to allow support for new color assignments, so perhaps there's something there.
You can use itertools.product

somelists = [
[1, 2, 3],
['a', 'b'],

This worked for me:
string string_test = "80123456";
unsigned long x;
signed long val;
std::stringstream ss;
ss << std::hex << string_test;
ss >> x;
// ss >> val; // if I try this val = 0
val = (signed long)x; // However, if I cast the unsigned result I get val = 0x80123456

If you have git installed, it's located in C:\Program Files\git\usr\bin.
Example:

Add somewhere in body
<div class="hide">
<a href="#" class="list-group-item">
<table>
<tr>
<td><img src=""></td>
<td><p class="list-group-item-text"></p></td>

</a>
</div>
then create css
.hide { display: none; }
and add to your js
$('#output').append( $('.hide').html() );

change the port may help as 80 port is already using somewhere
vi /etc/nginx/sites-available/default
Change the port:
listen 8080 default_server;
listen [::]:8080 default_server;
And then restart the nginx server
nginx -t
service nginx restart
in my case I show that the error log was going to /var/log/php-fpm/www-error.log . so I commented this line in /etc/php-fpm.d/www.conf
php_flag[display_errors] is commented
php_flag[display_errors] = on log will be at /var/log/php-fpm/www-error.log
and as said above I also uncommented this line
catch_workers_output = yes
Now I can see logs in the file specified by nginx.
PHP will work only on the .php
file extension.
If you are on Apache you can also set, in your httpd.conf
file, the extensions for PHP. You'll have to find the line:
AddType application/x-httpd-php .php .html
^^^^^
and add how many extensions, that should be read with the PHP interpreter, as you want.
This problem explained in MSDN Library and as I understand installing Microsoft's Redistributable Package can help.
But sometimes the following solution can be used (as developer's side solution):
In your Visual Studio, open Project properties -> Configuration properties -> C/C++ -> Code generation

instead of /MD
Bit late response to this question, however I do have something to add that might be useful for others.

I have improved @dacoinminster answer and this is the result with an example to share your app:
// Intents with SEND action
PackageManager packageManager = context.getPackageManager();
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
List<ResolveInfo> resolveInfoList = packageManager.queryIntentActivities(sendIntent, 0);
List<LabeledIntent> intentList = new ArrayList<LabeledIntent>();
Resources resources = context.getResources();
for (int j = 0; j < resolveInfoList.size(); j++) {
ResolveInfo resolveInfo = resolveInfoList.get(j);
String packageName = resolveInfo.activityInfo.packageName;
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setComponent(new ComponentName(packageName,
resolveInfo.activityInfo.name));
intent.setType("text/plain");
if (packageName.contains("twitter")) {
intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.twitter) + "https://play.google.com/store/apps/details?id=" + context.getPackageName());
} else {
// skip android mail and gmail to avoid adding to the list twice
if (packageName.contains("android.email") || packageName.contains("android.gm")) {
continue;
}
intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.largeTextForFacebookWhatsapp) + "https://play.google.com/store/apps/details?id=" + context.getPackageName());
}
intentList.add(new LabeledIntent(intent, packageName, resolveInfo.loadLabel(packageManager), resolveInfo.icon));
}
Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:"));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, resources.getString(R.string.subjectForMailApps));
emailIntent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.largeTextForMailApps) + "https://play.google.com/store/apps/details?id=" + context.getPackageName());
context.startActivity(Intent.createChooser(emailIntent, resources.getString(R.string.compartirEn)).putExtra(Intent.EXTRA_INITIAL_INTENTS, intentList.toArray(new LabeledIntent[intentList.size()])));
It means that there were some changes on the context which have not been executed. Please run Add-Migration first to generate the changes that we have done (the changes that we might not aware) And then run Update-Database
If you want to do a horizontal centering, just put the form inside a DIV tag and apply align="center" attribute to it. So even if the form width is changed, your centering will remain the same.
<div align="center"><form id="form_login"><!--form content here--></form></div>
UPDATE
@G-Cyr is right. align="center"
attribute is now obsolete. You can use text-align
attribute for this as following.
<div style="text-align:center"><form id="form_login"><!--form content here--></form></div>
This will center all the content inside the parent DIV. An optional way is to use margin: auto
CSS attribute with predefined widths and heights. Please follow the following thread for more information.
How to horizontally center a in another ?
Vertical centering is little difficult than that. To do that, you can do the following stuff.
html
<body>
<div id="parent">
<form id="form_login">
<!--form content here-->
</form>
</div>
</body>
Css
#parent {
display: table;
width: 100%;
}
#form_login {
display: table-cell;
text-align: center;
vertical-align: middle;
}

I know nothing about Jenkins, but it looks like you are trying to access environment variables using some form of unix syntax - that won't work.
If the name of the variable is WORKSPACE, then the value is expanded in Windows batch using
%WORKSPACE%
. That form of expansion is performed at parse time. For example, this will print to screen the value of WORKSPACE
echo %WORKSPACE%
If you need the value at execution time, then you need to use delayed expansion !WORKSPACE!
. Delayed expansion is not normally enabled by default. Use SETLOCAL EnableDelayedExpansion
to enable it. Delayed expansion is often needed because blocks of code within parentheses and/or multiple commands concatenated by &
, &&
, or ||
are parsed all at once, so a value assigned within the block cannot be read later within the same block unless you use delayed expansion.
setlocal enableDelayedExpansion
set WORKSPACE=BEFORE
(
set WORKSPACE=AFTER
echo Normal Expansion = %WORKSPACE%
echo Delayed Expansion = !WORKSPACE!
)
The output of the above is
Normal Expansion = BEFORE
Delayed Expansion = AFTER
Use HELP SET
or SET /?
from the command line to get more information about Windows environment variables and the various expansion options. For example, it explains how to do search/replace and substring operations.
$month = 10; // october

$lastday = date(date('t', strtotime($firstday)) .'-' . $month . '-Y');

This threw me for a long time too. The first thing I'd verify is that you're not reloading the page by clicking the refresh button, that will always issue a conditional request for resources and will return 304s for many of the page elements. Instead go up to the url bar select the page and hit enter as if you had just typed in the same URL again, that will give you a better indicator of what's being cached properly. This article does a great job explaining the difference between conditional and unconditional requests and how the refresh button affects them: http://blogs.msdn.com/b/ieinternals/archive/2010/07/08/technical-information-about-conditional-http-requests-and-the-refresh-button.aspx

By the way, you can use serialization technology to send strings, numbers or any objects which are support serialization (most of .NET data-storing classes & structs are [Serializable]). There, you should at first send Int32-length in four bytes to the stream and then send binary-serialized (System.Runtime.Serialization.Formatters.Binary.BinaryFormatter) data into it.
On the other side or the connection (on both sides actually) you definetly should have a byte[] buffer which u will append and trim-left at runtime when data is coming.

That is just an example, you should edit it for your use.
So use a semi-colon:

This doesn't work well if you want to supply arguments to the first command. Alternatively, create a trivial script in your $HOME/bin directory.
The httpd dæmon on OpenBSD uses the following stylesheet for all of its error messages, which presumably covers all the Comic Sans variations on non-Windows systems:
http://openbsd.su/src/usr.sbin/httpd/server_http.c#server_abort_http
810 style = "body { background-color: white; color: black; font-family: "
811 "'Comic Sans MS', 'Chalkboard SE', 'Comic Neue', sans-serif; }\n"
812 "hr { border: 0; border-bottom: 1px dashed; }\n";
E.g., try this:
font-family: 'Comic Sans MS', 'Chalkboard SE', 'Comic Neue', sans-serif;
AFAIK JSON.Net does not provide functionality for reading from a URL. So you need to do this in two steps:
using (var webClient = new System.Net.WebClient()) {
var json = webClient.DownloadString(URL);
// Now parse with JSON.Net
}
You cannot remove an IDENTITY
specification once set.
To remove the entire column:
ALTER TABLE yourTable
DROP COLUMN yourCOlumn;
Information about ALTER TABLE here
If you need to keep the data, but remove the IDENTITY
column, you will need to:
IDENTITY
column to the new columnIDENTITY
column.If you're using IPython, you can simply run:
%load path/to/your/file.py
