You first need to add values to your select
options and for easy targetting give the select
itself an id
.
Let's make option b
the default:
<select id="mySelect">
<option>a</option>
<option selected="selected">b</option>
<option>c</option>
</select>
Now you can change the default selected value with JavaScript like this:
<script>
var temp = "a";
var mySelect = document.getElementById('mySelect');
for(var i, j = 0; i = mySelect.options[j]; j++) {
if(i.value == temp) {
mySelect.selectedIndex = j;
break;
}
}
</script>
See it in action on codepen.
String1.scan(/<([^>]*)>/).last.first
scan
creates an array which, for each <item>
in String1
contains the text between the <
and the >
in a one-element array (because when used with a regex containing capturing groups, scan creates an array containing the captures for each match). last
gives you the last of those arrays and first
then gives you the string in it.
In smarty there is built in modifier you could use that by using |
(single pipeline operator). Like this {$varname|@print_r}
will print value as print_r($php_variable)
In angularjs you can create the UI part, service, Directives and all the part of angularjs which represent the UI. It is nice technology to work on.
As any one who new into this technology and want to authenticate the "User" then i suggest to do it with the power of c# web api. for that you can use the OAuth specification which will help you to built a strong security mechanism to authenticate the user. once you build the WebApi with OAuth you need to call that api for token:
var _login = function (loginData) {_x000D_
_x000D_
var data = "grant_type=password&username=" + loginData.userName + "&password=" + loginData.password;_x000D_
_x000D_
var deferred = $q.defer();_x000D_
_x000D_
$http.post(serviceBase + 'token', data, { headers: { 'Content-Type': 'application/x-www-form-urlencoded' } }).success(function (response) {_x000D_
_x000D_
localStorageService.set('authorizationData', { token: response.access_token, userName: loginData.userName });_x000D_
_x000D_
_authentication.isAuth = true;_x000D_
_authentication.userName = loginData.userName;_x000D_
_x000D_
deferred.resolve(response);_x000D_
_x000D_
}).error(function (err, status) {_x000D_
_logOut();_x000D_
deferred.reject(err);_x000D_
});_x000D_
_x000D_
return deferred.promise;_x000D_
_x000D_
};_x000D_
_x000D_
and once you get the token then you request the resources from angularjs with the help of Token and access the resource which kept secure in web Api with OAuth specification.

What kind of data?
data: $('#myForm').serialize() + "&moredata=" + morevalue
The "data" parameter is just a URL encoded string. You can append to it however you like. See the API here.

Here is another method:
public static string ByteArrayToHexString(byte[] Bytes)
{
StringBuilder Result = new StringBuilder(Bytes.Length * 2);
string HexAlphabet = "0123456789ABCDEF";
foreach (byte B in Bytes)
{
Result.Append(HexAlphabet[(int)(B >> 4)]);
Result.Append(HexAlphabet[(int)(B & 0xF)]);
}
return Result.ToString();
}
public static byte[] HexStringToByteArray(string Hex)
{
byte[] Bytes = new byte[Hex.Length / 2];
int[] HexValue = new int[] { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05,
0x06, 0x07, 0x08, 0x09, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F };
for (int x = 0, i = 0; i < Hex.Length; i += 2, x += 1)
{
Bytes[x] = (byte)(HexValue[Char.ToUpper(Hex[i + 0]) - '0'] << 4 |
HexValue[Char.ToUpper(Hex[i + 1]) - '0']);
}
return Bytes;
}
Alternatively, you could pre-build the translation table like so to achieve even faster results:
Don't provide the handler to execute
.
Get the HttpResponse
object, use the handler to get the body and get the status code from it directly
try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
final HttpGet httpGet = new HttpGet(GET_URL);
try (CloseableHttpResponse response = httpClient.execute(httpGet)) {
StatusLine statusLine = response.getStatusLine();
System.out.println(statusLine.getStatusCode() + " " + statusLine.getReasonPhrase());
String responseBody = EntityUtils.toString(response.getEntity(), StandardCharsets.UTF_8);
System.out.println("Response body: " + responseBody);
}
}
For quick single calls, the fluent API is useful:
Response response = Request.Get(uri)
.connectTimeout(MILLIS_ONE_SECOND)
.socketTimeout(MILLIS_ONE_SECOND)
.execute();
HttpResponse httpResponse = response.returnResponse();
StatusLine statusLine = httpResponse.getStatusLine();
For older versions of java or httpcomponents, the code might look different.
A much better way is to use inline-block
, because you don't need to use clear:both
at the end of your list anymore.
Try this:
<ul>
<li>
<a href="#">some item</a>
</li>
<li>
<a href="#">another item</a>
</li>
</ul>
CSS:
ul > li{
display:inline-block;
}

Just use: android:layout_centerHorizontal="true"
It will put the whole textview in the center
If you want type safety and a bunch of constants that match that type, one way to go is to have an abstract class for your enum and then extend that class with a locked constructor, like so:
abstract class DaysOfWeekEnum{
public function __construct(string $value){
$this->value = $value;
}
public function __toString(){
return $this->value;
}
}
class Monday extends DaysOfWeekEnum{
public function __construct(){
parent::__construct("Monday");
}
}
class Tuesday extends DaysOfWeekEnum{
public function __construct(){
parent::__construct("Tuesday");
}
}
Then you can have your methods take an instance of DaysOfWeek and pass it an instance of Monday, Tuesday, etc... The only downside is having to 'new-up' an instance every time you want to use your enum, but I find it worth it.
function printWeekDay(DaysOfWeek $day){
echo "Today is $day.";
}
printWeekDay(new Monday());
You can use WordPress predefined function to add script file to WordPress plugin.
wp_enqueue_script( 'script', plugins_url('js/demo_script.js', __FILE__), array('jquery'));
Look at the post which helps you to understand that how easily you can implement jQuery and CSS in WordPress plugin.
Add this line before main function:
void swapCase (char* name);
int main()
{
...
swapCase(name); // swapCase prototype should be known at this point
...
}
This is called forward declaration: compiler needs to know function prototype when function call is compiled.
Use this code:
'{:x}'.format(int(line))
it allows you to specify a number of digits too:
'{:06x}'.format(123)
# '00007b'
For Python 2.6 use
'{0:x}'.format(int(line))
or
'{0:06x}'.format(int(line))
public ActionResult SomeAction(string start, string end)
The framework will map the query string parameters to the method parameters.
This sounds like you're using numpy.
If that's the case, you can add:
import numpy as np
np.set_printoptions(threshold=np.nan)
That will disable the corner printing. For more information, see this NumPy Tutorial.
Latest revision based on comment from BinaryZebra's comment
and tested here. The addition of command eval
allows for the expression to be kept in the present execution environment while the expressions before are only held for the duration of the eval.
Use $IFS that has no spaces\tabs, just newlines/CR
$ IFS=$'\r\n' GLOBIGNORE='*' command eval 'XYZ=($(cat /etc/passwd))'
$ echo "${XYZ[5]}"
sync:x:5:0:sync:/sbin:/bin/sync
Also note that you may be setting the array just fine but reading it wrong - be sure to use both double-quotes ""
and braces {}
as in the example above
Edit:
Please note the many warnings about my answer in comments about possible glob expansion, specifically gniourf-gniourf's comments about my prior attempts to work around
With all those warnings in mind I'm still leaving this answer here (yes, bash 4 has been out for many years but I recall that some macs only 2/3 years old have pre-4 as default shell)
Other notes:
Can also follow drizzt's suggestion below and replace a forked subshell+cat with
$(</etc/passwd)
The other option I sometimes use is just set IFS into XIFS, then restore after. See also Sorpigal's answer which does not need to bother with this
Query query = session.createQuery("from Employee");
Note: from Employee. here Employee is not your table name it's POJO name.
As other answers have pointed, on UNIX systems the numbers represent CPU load averages over 1/5/15 minute periods. But on Linux (and consequently Android), what it represents is something different.
After a kernel patch dating back to 1993 (a great in-depth article on the subject), in Linux the load average numbers no longer strictly represent the CPU load: as the calculation accounts not only for CPU bound processes, but also for processes in uninterruptible wait state - the original goal was to account for I/O bound processes this way, to represent more of a "system load" than just CPU load. The issue is that since 1993 the usage of uninterruptible state has grown in Linux kernel, and it no longer typically represents an I/O bound process. The problem is further exacerbated by some Linux devs using uninterruptible waits as an easy wait to avoid accommodating signals in their implementations. As a result, in Linux (and Android) we can see skewed high load average numbers that do not objectively represent the real load. There are Android user reports about unreasonable high load averages contrasting low CPU utilization. For example, my old Android phone (with 2 CPU cores) normally shown average load of ~12 even when the system and CPUs were idle. Hence, average load numbers in Linux (Android) does not turn out to be a reliable performance metric.
Going one step further, uploading to iTunesConnect via commandline with Xcode 7!
(Assuming you are starting with an .ipa
that has been signed with the correct release profile and signing identity.)
Enter altool
, the CLI interface for the Application Loader (docs
, page 38).
Hidden deep within Xcode.app's structure, is a handy function to let us upload directly to ItunesConnect.
/Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/Frameworks/ITunesSoftwareService.framework/Versions/A/Support/altool
Simply run $ altool --upload-app -f file -u username [-p password]
to upload your newly minted .ipa
straight to Apple.
The password is optional, and will prompt you for it if you leave it off the command.
If there are any issues with the app during the verification step, the console will print them out.
You will likely have to export the path to altool
if you don't want to save its location.
export PATH=$PATH:/Applications/Xcode.app/Contents/Applications/Application\ Loader.app/Contents/Frameworks/ITunesSoftwareService.framework/Versions/A/Support/
Thats it! Simply login to iTunesConnect.com and select your new build for testing with testflight.
Final Note: If you get an error saying Exception while launching iTunesTransporter: Transporter not found at path: /usr/local/itms/bin/iTMSTransporter. You should reinstall the application
, you can follow the suggestion on this SO answer, to run a symlink to the correct location:
ln -s /Applications/Xcode.app/Contents/Applications/Application\ Loader.app/Contents/itms /usr/local/itms
there are two columns in the a table ID and name where names are repeating with different IDs so for that you may use this query: . .
DELETE FROM dbo.tbl1
WHERE id NOT IN (
Select MIN(Id) AS namecount FROM tbl1
GROUP BY Name
)
In
you can do:
db.users.find({'name': {'$regex': 'sometext'}})

printf "y\npassword\n" | sh test.sh
where \n
is escape-sequence
If an Immutable/Singleton collections refers to the one which having only one object and which is not further gets modified, then the same functionality can be achieved by making a collection "UnmodifiableCollection" having only one object. Since the same functionality can be achieved by Unmodifiable Collection with one object, then what special purpose the Singleton Collection serves for?
Something else that was not obvious, to me at least, was that the when using Mongoose's third parameter to avoid replacing the actual collection with a new one with the same name, the new Schema(...)
is actually only a placeholder, and doesn't interfere with the exisitng schema so
var User = mongoose.model('User', new Schema({ url: String, text: String, id: Number}, { collection : 'users' })); // collection name;
User.find({}, function(err, data) { console.log(err, data, data.length);});
works fine and returns all fields - even if the actual (remote) Schema contains none of these fields. Mongoose will still want it as new Schema(...)
, and a variable almost certainly won't hack it.
If the behavior of for(... in ...) is acceptable/necessary for your purposes, you can tell tslint to allow it.
in tslint.json, add this to the "rules" section.

In your link function, do this:
// link function
function (scope, element, attrs) {
var myEl = angular.element(element[0].querySelector('.list-scrollable'));
}
Also, in your link function, don't name your scope
variable using a $
. That is an angular convention that is specific to built in angular services, and is not something that you want to use for your own variables.
You can do this using a group by:
select id, addressCode
from t
group by id, addressCode
having min(address) <> max(address)
Another way of writing this may seem clearer, but does not perform as well:
select id, addressCode
from t
group by id, addressCode
having count(distinct address) > 1
OP is asking for a "save" function, which is more than just preserving data across executions of the program (which you must do for the app to be worth anything.)
I recommend saving the data in a file on the sdcard which allows you to not only recall it later, but allows the user to mount the device as an external drive on their own computer and grab the data for use in other places.
So you really need a multi-point system:
1) Implement onSaveInstanceState()
. In this method, you're passed a Bundle, which is basically like a dictionary. Store as much information in the bundle as would be needed to restart the app exactly where it left off. In your onCreate()
method, check for the passed-in bundle to be non-null, and if so, restore the state from the bundle.
2) Implement onPause()
. In this method, create a SharedPreferences editor and use it to save whatever state you need to start the app up next time. This mainly consists of the users' preferences (hence the name), but anything else relavent to the app's start-up state should go here as well. I would not store scores here, just the stuff you need to restart the app. Then, in onCreate()
, whenever there's no bundle object, use the SharedPreferences interface to recall those settings.
3a) As for things like scores, you could follow Mathias's advice above and store the scores in the directory returned in getFilesDir()
, using openFileOutput()
, etc. I think this directory is private to the app and lives in main storage, meaning that other apps and the user would not be able to access the data. If that's ok with you, then this is probably the way to go.
3b) If you do want other apps or the user to have direct access to the data, or if the data is going to be very large, then the sdcard is the way to go. Pick a directory name like com/user1446371/basketballapp/ to avoid collisions with other applications (unless you're sure that your app name is reasonably unique) and create that directory on the sdcard. As Mathias pointed out, you should first confirm that the sdcard is mounted.
File sdcard = Environment.getExternalStorageDirectory();
if( sdcard == null || !sdcard.isDirectory()) {
fail("sdcard not available");
}
File datadir = new File(sdcard, "com/user1446371/basketballapp/");
if( !datadir.exists() && !datadir.mkdirs() ) {
fail("unable to create data directory");
}
if( !datadir.isDirectory() ) {
fail("exists, but is not a directory");
}
// Now use regular java I/O to read and write files to data directory
I recommend simple CSV files for your data, so that other applications can read them easily.
Obviously, you'll have to write activities that allow "save" and "open" dialogs. I generally just make calls to the openintents file manager and let it do the work. This requires that your users install the openintents file manager to make use of these features, however.
There is an old Bugreport concerning this issue.
You can't do this: {this.state.arrayFromJson}
As your error suggests what you are trying to do is not valid. You are trying to render the whole array as a React child. This is not valid. You should iterate through the array and render each element. I use .map
to do that.
I am pasting a link from where you can learn how to render elements from an array with React.

This is a potential duplicate of Finding rows that don't contain numeric data in Oracle. Also see: How can I determine if a string is numeric in SQL?.
Here's a solution based on Michael Durrant's that works for integers.

WHERE DECODE(TRIM(TRANSLATE(your_number,'0123456789',' ')), NULL, 'number','contains char') = 'number'
Adrian Carneiro posted a solution that works for decimals and others. However, as Justin Cave pointed out, this will incorrectly classify strings like '123.45.23.234' or '131+234'.
SELECT foo
FROM bar
WHERE DECODE(TRIM(TRANSLATE(your_number,'+-.0123456789',' ')), NULL, 'number','contains char') = 'number'

queries. As per the documentation:
For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command. When a trigger exists on a table being inserted or updated, the return value includes the number of rows affected by both the insert or update operation and the number of rows affected by the trigger or triggers. For all other types of statements, the return value is -1.

Some complements to Fedor Gogolev answer:
First, if the string contains characters whose 'ASCII code' is below 10, they will not be displayed as required. In that case, the correct format should be {:02x}
:
>>> s = "Hello unicode \u0005 !!"
>>> ":".join("{0:x}".format(ord(c)) for c in s)
'48:65:6c:6c:6f:20:75:6e:69:63:6f:64:65:20:5:20:21:21'
^
>>> ":".join("{:02x}".format(ord(c)) for c in s)
'48:65:6c:6c:6f:20:75:6e:69:63:6f:64:65:20:05:20:21:21'
^^
Second, if your "string" is in reality a "byte string" -- and since the difference matters in Python 3 -- you might prefer the following:
>>> s = b"Hello bytes \x05 !!"
>>> ":".join("{:02x}".format(c) for c in s)
'48:65:6c:6c:6f:20:62:79:74:65:73:20:05:20:21:21'
Please note there is no need for conversion in the above code as a bytes objects is defined as "an immutable sequence of integers in the range 0 <= x < 256".
June 2014:
This is the configuration I used and it working fine after banging my head on the wall for some days. I use Express 3.4 (I think is the same for Express 4.0)
var privateKey = fs.readFileSync('helpers/sslcert/key.pem', 'utf8');
var certificate = fs.readFileSync('helpers/sslcert/csr.pem', 'utf8');
files = ["COMODORSADomainValidationSecureServerCA.crt",
"COMODORSAAddTrustCA.crt",
"AddTrustExternalCARoot.crt"
];
ca = (function() {
var _i, _len, _results;
_results = [];
for (_i = 0, _len = files.length; _i < _len; _i++) {
file = files[_i];
_results.push(fs.readFileSync("helpers/sslcert/" + file));
}
return _results;
})();
var credentials = {ca:ca, key: privateKey, cert: certificate};
// process.env.PORT : Heroku Config environment
var port = process.env.PORT || 4000;
var app = express();
var server = http.createServer(app).listen(port, function() {
console.log('Express HTTP server listening on port ' + server.address().port);
});
https.createServer(credentials, app).listen(3000, function() {
console.log('Express HTTPS server listening on port ' + server.address().port);
});
// redirect all http requests to https
app.use(function(req, res, next) {
if(!req.secure) {
return res.redirect(['https://mydomain.com', req.url].join(''));
}
next();
});
Then I redirected the 80 and 443 ports:
sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 4000
sudo iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-ports 3000

With
git config -l
, I now see I have acredential.helper=osxkeychain
option
That means the credential helper (initially introduced in 1.7.10) is now in effect, and will cache automatically the password for accessing a remote repository over HTTP.
(as in "GIT: Any way to set default login credentials?")
You can disable that option entirely, or only for a single repo.
You can achieve that using DATE_FORMAT() (click the link for more other formats)
SELECT DATE_FORMAT(colName, '%Y-%m-%d') DATEONLY,
DATE_FORMAT(colName,'%H:%i:%s') TIMEONLY
The Android SDK can tell you this just fine:
getResources().getConfiguration().orientation
There are a few efficient ways to implement this. Let's start with required imports:
from pyspark.sql.functions import col, expr, when
You can use Hive IF
function inside expr:
new_column_1 = expr(
"""IF(fruit1 IS NULL OR fruit2 IS NULL, 3, IF(fruit1 = fruit2, 1, 0))"""
)
or when
+ otherwise
:
new_column_2 = when(
col("fruit1").isNull() | col("fruit2").isNull(), 3
).when(col("fruit1") == col("fruit2"), 1).otherwise(0)
Finally you could use following trick:
from pyspark.sql.functions import coalesce, lit
new_column_3 = coalesce((col("fruit1") == col("fruit2")).cast("int"), lit(3))
With example data:
df = sc.parallelize([
("orange", "apple"), ("kiwi", None), (None, "banana"),
("mango", "mango"), (None, None)
]).toDF(["fruit1", "fruit2"])
you can use this as follows:
(df
.withColumn("new_column_1", new_column_1)
.withColumn("new_column_2", new_column_2)
.withColumn("new_column_3", new_column_3))
and the result is:
+------+------+------------+------------+------------+
|fruit1|fruit2|new_column_1|new_column_2|new_column_3|
+------+------+------------+------------+------------+
|orange| apple| 0| 0| 0|
| kiwi| null| 3| 3| 3|
| null|banana| 3| 3| 3|
| mango| mango| 1| 1| 1|
| null| null| 3| 3| 3|
+------+------+------------+------------+------------+
You could also use operator.concat()
like this:
>>> from operator import concat
>>> a = ['a', 'b', 'c', 'd']
>>> reduce(concat, a)
'abcd'
If you're using Python 3 you need to prepend:
>>> from functools import reduce
since the builtin reduce()
has been removed from Python 3 and now lives in functools.reduce()

Keep in mind that you will need the appropriate rights. The permissions are called "Undo other users' changes" and "Unlock other users' changes". These permissions can be viewed by:
Disclaimer: this answer is an edited repost of Brett Roger's answer to a similar question.
alt and title are for different things, as already mentioned. While the title attribute will provide a tooltip, alt is also an important attribute, since it specifies text to be displayed if the image can't be displayed. (And in some browsers, such as firefox, you'll also see this text while the image loads)
Another point that I feel should be made is that the alt attribute is required to validate as an XHTML document, whereas the title attribute is just an "extra option," as it were.
A common mistake is
mainWB.Sheets.Add(After:=Sheets.Count)
which leads to Error 1004. Although it is not clear at all from the official documentation, it turns out that the 'After' parameter cannot be an integer, it must be a reference to a sheet in the same workbook.
I am reproducing the same issue and it's really annoying. I've found these useful:

var x = await c.GetAsync("http://linqpad.net", cts.Token);
}

Thanks! Here is a C# version of OP's solutions using degrees. It utilises the System.Device.Location.GeoCoordinate class
public static GeoCoordinate GetCentralGeoCoordinate(
IList<GeoCoordinate> geoCoordinates)
{
if (geoCoordinates.Count == 1)
{
return geoCoordinates.Single();
}
double x = 0;
double y = 0;
double z = 0;
foreach (var geoCoordinate in geoCoordinates)
{
var latitude = geoCoordinate.Latitude * Math.PI / 180;
var longitude = geoCoordinate.Longitude * Math.PI / 180;
x += Math.Cos(latitude) * Math.Cos(longitude);
y += Math.Cos(latitude) * Math.Sin(longitude);
z += Math.Sin(latitude);
}
var total = geoCoordinates.Count;
x = x / total;
y = y / total;
z = z / total;
var centralLongitude = Math.Atan2(y, x);
var centralSquareRoot = Math.Sqrt(x * x + y * y);
var centralLatitude = Math.Atan2(z, centralSquareRoot);
return new GeoCoordinate(centralLatitude * 180 / Math.PI, centralLongitude * 180 / Math.PI);
}

const mapper = ({id}) => id
const isArrayWithEqualEntries = array => new Set(array.map(mapper)).size === 1

Wow, ya'll are overthinking it. It's as simple as the following. Besides, many of those answers aren't understood by the RE2 dialect used by C and golang.

The problem:
java.lang.ClassNotFoundException: org.glassfish.jersey.servlet.ServletContainer
indicates that you try to use the Jersey 2.x servlet, but you are supplying the Jersey 1.x libs.
For Jersey 1.x you have to do it like this:
<servlet>
<servlet-name>Jersey REST Service</servlet-name>
<servlet-class>
com.sun.jersey.spi.container.servlet.ServletContainer
</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>sample.hello.resources</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Jersey REST Service</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
For more information check the Jersey 1.x documentation.
If you instead want to use Jersey 2.x then you'll have to supply the Jersey 2.x libs. In a maven based project you can use the following:
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet</artifactId>
<version>2.xx</version>
</dependency>
<!-- if you are using Jersey client specific features without the server side -->
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-client</artifactId>
<version>2.xx</version>
</dependency>
For Jersey 2.x you don't need to setup anything in your web.xml
, it is sufficient to supply a class similar to this:
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
@ApplicationPath("rest")
public class ApplicationConfig extends Application {
}
For more information, check the Jersey documentation.

From Python Cookbook v.30
def myfun():
return 1, 2, 3
a, b, c = myfun()
Although it looks like
myfun()
returns multiple values, atuple
is actually being created. It looks a bit peculiar, but it’s actually the comma that forms a tuple, not the parentheses
So yes, what's going on in Python is an internal transformation from multiple comma separated values to a tuple and vice-versa.
Though there's no equivalent in java you can easily create this behaviour using array
's or some Collection
s like List
s:
private static int[] sumAndRest(int x, int y) {
int[] toReturn = new int[2];
toReturn[0] = x + y;
toReturn[1] = x - y;
return toReturn;
}
Executed in this way:
public static void main(String[] args) {
int[] results = sumAndRest(10, 5);
int sum = results[0];
int rest = results[1];
System.out.println("sum = " + sum + "\nrest = " + rest);
}
result:
sum = 15
rest = 5
You can't add a new unique auto-generated ID to a SharePoint list, but there already is one there! If you edit the "All Items" view you will see a list of columns that do not have the display option checked.
There are quite a few of these columns that exist but that are never displayed, like "Created By" and "Created". These fields are used within SharePoint, but they are not displayed by default so as not to clutter up the display. You can't edit these fields, but you can display them to the user. if you check the "Display" box beside the ID field you will get a unique and auto-generated ID field displayed in your list.

From the javadoc of java.rmi.registry.Registry
Therefore, a registry's remote object implementation is typically exported with a well-known address, such as with a well-known

So Why not use powershell to create the list of source files for you. Take a look at this script
param (
[Parameter(Mandatory=$True)]
[string]$root
)
if (-not (Test-Path -Path $root)) {
throw "Error directory does not exist"
}
#get the full path of the root
$rootDir = get-item -Path $root
$fp=$rootDir.FullName;
$files = Get-ChildItem -Path $root -Recurse -File |
Where-Object { ".cpp",".cxx",".cc",".h" -contains $_.Extension} |
Foreach {$_.FullName.replace("${fp}\","").replace("\","/")}
$CMakeExpr = "set(SOURCES "
foreach($file in $files){
$CMakeExpr+= """$file"" " ;
}
$CMakeExpr+=")"
return $CMakeExpr;
Suppose you have a folder with this structure
C:\Workspace\A
--a.cpp
C:\Workspace\B
--b.cpp
Now save this file as "generateSourceList.ps1" for example, and run the script as
~>./generateSourceList.ps1 -root "C:\Workspace" > out.txt
out.txt file will contain
set(SOURCE "A/a.cpp" "B/b.cpp")
Use xlsread, it works just as well on .csv files as it does on .xls files. Specify that you want three outputs:
[num char raw] = xlsread('your_filename.csv')
and it will give you an array containing only the numeric data (num), an array containing only the character data (char) and an array that contains all data types in the same format as the .csv layout (raw).

{
tbl.Rows.Add(selector.Invoke(item));

I tested the ByteBuffer method against plain bitwise operations but the latter is significantly faster.
public static byte[] longToBytes(long l) {
byte[] result = new byte[8];
for (int i = 7; i >= 0; i--) {
result[i] = (byte)(l & 0xFF);
l >>= 8;
}
return result;
}
public static long bytesToLong(final byte[] b) {
long result = 0;
for (int i = 0; i < 8; i++) {
result <<= 8;
result |= (b[i] & 0xFF);
}
return result;
}
For Java 8+ we can use the static variables that were added:
public static byte[] longToBytes(long l) {
byte[] result = new byte[Long.BYTES];
for (int i = Long.BYTES - 1; i >= 0; i--) {
result[i] = (byte)(l & 0xFF);
l >>= Byte.SIZE;
}
return result;
}
public static long bytesToLong(final byte[] b) {
long result = 0;
for (int i = 0; i < Long.BYTES; i++) {
result <<= Byte.SIZE;
result |= (b[i] & 0xFF);
}
return result;
}
If the commit you want to revert is a merged commit (has been merged already), then you should either -m 1

I solved this problem on Github separating the indented sub-block with a newline, for instance, you write the item 1, then hit enter twice (like if it was a new paragraph), indent the block and write what you want (a block of code, text, etc). More information on Markdown lists and Markdown line breaks.
item two
this block acts as a new paragraph, above there is a blank line

There are two ways to interpret the input data; either -128 is the lowest value, and 127 is the highest (i.e. true signed data), or 0 is the lowest value, 127 is somewhere in the middle, and the next "higher" number is -128, with -1 being the "highest" value (that is, the most significant bit already got misinterpreted as a sign bit in a two's complement notation.
Assuming you mean the latter, the formally correct way is
signed char in = ...
unsigned char out = (in < 0)?(in + 256):in;
which at least gcc properly recognizes as a no-op.
None of the above helped for me.

Having seen your fiddle in the comments the issue is quite easy to fix. You just need to add overflow:auto
or set a specific height to your div
. Live example: http://jsfiddle.net/tw16/xRcXL/3/
.Tab{
overflow:auto; /* add this */
border:solid 1px #faa62a;
border-bottom:none;
padding:7px 10px;
background:-moz-linear-gradient(center top , #FAD59F, #FA9907) repeat scroll 0 0 transparent;
background:-webkit-gradient(linear, left top, left bottom, from(#fad59f), to(#fa9907));
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#fad59f, endColorstr=#fa9907);
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#fad59f, endColorstr=#fa9907)";
}
I'll vote for sb.setLength(0);
not only because it's one function call, but because it doesn't actually copy the array into another array like sb.delete(0, builder.length());
. It just fill the remaining characters to be 0 and set the length variable to the new length.
You can take a look into their implementation to validate my point from here at setLength
function and delete0
function.
You can also try using apply
with get
method of dictionary
, seems to be little faster than replace
:
data['sex'] = data['sex'].apply({1:'Male', 0:'Female'}.get)
Testing with timeit
:
%%timeit
data['sex'].replace([0,1],['Female','Male'],inplace=True)
Result:
The slowest run took 5.83 times longer than the fastest. This could mean that an intermediate result is being cached.
1000 loops, best of 3: 510 µs per loop
Using apply
:
%%timeit
data['sex'] = data['sex'].apply({1:'Male', 0:'Female'}.get)
Result:
The slowest run took 5.92 times longer than the fastest. This could mean that an intermediate result is being cached.
1000 loops, best of 3: 331 µs per loop
Note: apply
with dictionary should be used if all the possible values of the columns in the dataframe are defined in the dictionary else, it will have empty for those not defined in dictionary.

Here is a fiddle with another example: http://jsfiddle.net/YYPKM/3/
You can use an alert dialog
AlertDialog.Builder b = new Builder(this);
b.setTitle("Example");
String[] types = {"By Zip", "By Category"};
b.setItems(types, new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
switch(which){
case 0:
onZipRequested();
break;
case 1:
onCategoryRequested();
break;
}
}
});
b.show();
This will close the dialog when one of them is pressed like you are wanting. Hope this helps!

I would recommend giving the LI
a background-image
and padding-left
. The list-style-image
attribute is flakey in cross-browser environments, and adding an extra element, such as a span, is unneccessary. So your code would end up looking something like this:
li {
background:url(../images/bullet.png) 0 0 no-repeat;
list-style:none;
padding-left:10px;
}
Depending on how often you use this in your code you could consider the following:
macro
#define SIGN(x) ( (x) >= 0 )
Inline function
inline int sign(int x)
{
return x >= 0;
}
Then you would just go:
bigInt.sign = sign(number);

For question #1, let's break it into two parts. First, increment any document that has "items.item_name" equal to "my_item_two". For this you'll have to use the positional "$" operator. Something like:
db.bar.update( {user_id : 123456 , "items.item_name" : "my_item_two" } ,
{$inc : {"items.$.price" : 1} } ,
false ,
true);
Note that this will only increment the first matched subdocument in any array (so if you have another document in the array with "item_name" equal to "my_item_two", it won't get incremented). But this might be what you want.
The second part is trickier. We can push a new item to an array without a "my_item_two" as follows:
db.bar.update( {user_id : 123456, "items.item_name" : {$ne : "my_item_two" }} ,
{$addToSet : {"items" : {'item_name' : "my_item_two" , 'price' : 1 }} } ,
false ,
true);
For your question #2, the answer is easier. To increment the total and the price of item_three in any document that contains "my_item_three," you can use the $inc operator on multiple fields at the same time. Something like:
db.bar.update( {"items.item_name" : {$ne : "my_item_three" }} ,
{$inc : {total : 1 , "items.$.price" : 1}} ,
false ,
true);
You need the stat call, and the file name:
my $last_mod_time = (stat ($file))[9];
Perl also has a different version:
my $last_mod_time = -M $file;
but that value is relative to when the program started. This is useful for things like sorting, but you probably want the first version.
This work for me in .NET Core 3.1.
But not in .NET 5 preview 7.

Answer, wrapped up in a function, with annotated interactive session:
>>> import re
>>> def special_match(strg, search=re.compile(r'[^a-z0-9.]').search):
... return not bool(search(strg))
...
>>> special_match("")
True
>>> special_match("az09.")
True
>>> special_match("az09.\n")
False
# The above test case is to catch out any attempt to use re.match()
# with a `$` instead of `\Z` -- see point (6) below.
>>> special_match("az09.#")
False
>>> special_match("az09.X")
False
>>>
Note: There is a comparison with using re.match() further down in this answer. Further timings show that match() would win with much longer strings; match() seems to have a much larger overhead than search() when the final answer is True; this is puzzling (perhaps it's the cost of returning a MatchObject instead of None) and may warrant further rummaging.
==== Earlier text ====
The [previously] accepted answer could use a few improvements:
(1) Presentation gives the appearance of being the result of an interactive Python session:
reg=re.compile('^[a-z0-9\.]+$')
>>>reg.match('jsdlfjdsf12324..3432jsdflsdf')
True
but match() doesn't return True
(2) For use with match(), the ^
at the start of the pattern is redundant, and appears to be slightly slower than the same pattern without the ^
(3) Should foster the use of raw string automatically unthinkingly for any re pattern
(4) The backslash in front of the dot/period is redundant
(5) Slower than the OP's code!

Choose one you need:
>>> s = "Rajasekar SP def"
>>> s.split(' ')
['Rajasekar', 'SP', '', 'def']
>>> s.split()
['Rajasekar', 'SP', 'def']
>>> s.partition(' ')
('Rajasekar', ' ', 'SP def')
Another option is Sheet1.Rows(x & ":" & Sheet1.Rows.Count).ClearContents
(or .Clear
). The reason you might want to use this method instead of .Delete
is because any cells with dependencies in the deleted range (e.g. formulas that refer to those cells, even if empty) will end up showing #REF
. This method will preserve formula references to the cleared cells.

You can use hasOwnProperty, but based on the reference you need quotes when using this method:
if (myObj.hasOwnProperty('myProp')) {
// do something
}
Another way is to use in operator, but you need quotes here as well:
if ('myProp' in myObj) {
// do something
}

Most Git repositories use master
as the main (and default) branch - if you initialize a new Git repo via git init
, it will have master
checked out by default.
However, if you clone a repository, the default branch you have is whatever the remote's HEAD
points to (HEAD
is actually a symbolic ref that points to a branch name). So if the repository you cloned had a HEAD
pointed to, say, foo
, then your clone will just have a foo
branch.
The remote you cloned from might still have a master
branch (you could check with git ls-remote origin master
), but you wouldn't have created a local version of that branch by default, because git clone
only checks out the remote's HEAD
.
I'm answering on specific to this error code(08s01).
usually, MySql close socket connections are some interval of time that is wait_timeout defined on MySQL server-side which by default is 8hours. so if a connection will timeout after this time and the socket will throw an exception which SQLState is "08s01".
1.use connection pool to execute Query, make sure the pool class has a function to make an inspection of the connection members before it goes time_out.
2.give a value of <wait_timeout> greater than the default, but the largest value is 24 days
3.use another parameter in your connection URL, but this method is not recommended, and maybe deprecated.

For anyone looking at this old post, this is the easiest way to do it currently. It only requires an AngularJS $filter
. Its like Willemoes answer, but shorter and easier to understand.
{
"results": [
{
"id": 1,
"name": "Test"
},
{
"id": 2,
"name": "Beispiel"
},
{
"id": 3,
"name": "Sample"
}
]
}
var object_by_id = $filter('filter')(foo.results, {id: 2 })[0];
// Returns { id: 2, name: "Beispiel" }
WARNING
As @mpgn says, this doesn't work properly. This will catch more results. Example: when you search 3 this will catch 23 too

Global title: In newer releases of matplotlib one can use Figure.suptitle() method of Figure
:
import matplotlib.pyplot as plt
fig = plt.gcf()
fig.suptitle("Title centered above all subplots", fontsize=14)
Alternatively (based on @Steven C. Howell's comment below (thank you!)), use the matplotlib.pyplot.suptitle() function:
import matplotlib.pyplot as plt
# plot stuff
# ...
plt.suptitle("Title centered above all subplots", fontsize=14)
Are you using Hibernate's Query
object, or JPA? For JPA, it should work fine:
String jpql = "from A where name in (:names)";
Query q = em.createQuery(jpql);
q.setParameter("names", l);
For Hibernate's, you'll need to use the setParameterList:
String hql = "from A where name in (:names)";
Query q = s.createQuery(hql);
q.setParameterList("names", l);
Try this:
$('input[name=Comanda]')
.click(
function ()
{
$(this).hide();
}
);
For doing everything else you can use something like this one:
$('input[name=Comanda]')
.click(
function ()
{
$(this).hide();
$(".ClassNameOfShouldBeHiddenElements").hide();
}
);
For hidding any other elements based on their IDs, use this one:
$('input[name=Comanda]')
.click(
function ()
{
$(this).hide();
$("#FirstElement").hide();
$("#SecondElement").hide();
$("#ThirdElement").hide();
}
);
Use forward slashes to specify the UNC Path:
open('//HOST/share/path/to/file')

Above many answers but doesn't work for me some of them no exception handling in correct way. here am adding a perfect solution work amazing for me sure also for you too.

Pickle is best for these cases. Suppose you have a ndarray named x_train
. You can dump it into a file and revert it back using the following command:
import pickle
###Load into file
with open("myfile.pkl","wb") as f:
pickle.dump(x_train,f)
###Extract from file
with open("myfile.pkl","rb") as f:
x_temp = pickle.load(f)

This should work properly. 1. use .value instead of "innerHTML" when setting the 3rd field (input field) 2. Close the input tags
Newer versions of pandas do allow you to pass extra arguments (see the new documentation). So now you can do:
my_series.apply(your_function, args=(2,3,4), extra_kw=1)
The positional arguments are added after the element of the series.
For older version of pandas:
The documentation explains this clearly. The apply method accepts a python function which should have a single parameter. If you want to pass more parameters you should use functools.partial
as suggested by Joel Cornett in his comment.
An example:
>>> import functools
>>> import operator
>>> add_3 = functools.partial(operator.add,3)
>>> add_3(2)
5
>>> add_3(7)
10
You can also pass keyword arguments using partial
.
Another way would be to create a lambda:
my_series.apply((lambda x: your_func(a,b,c,d,...,x)))
But I think using partial
is better.

From the article Override equals and hashCode in Java:
Default implementation of equals() class provided by java.lang.Object compares memory location and only return true if two reference variable are pointing to same memory location i.e. essentially they are same object.
Java recommends to override equals and hashCode method if equality is going to be defined by logical way or via some business logic: example:
many classes in Java standard library does override it e.g. String overrides equals, whose implementation of equals() method return true if content of two String objects are exactly same
Integer wrapper class overrides equals to perform numerical comparison etc.
You can do that in this way:
ORDER BY `products`.`product_category_id` DESC ,`naam` ASC

buffer before reading. From the man page:
For output streams, fflush() forces a write of all user-space buffered data for the given output or update stream via the stream's underlying write function. For input streams, fflush() discards any buffered data that has been fetched from the underlying file, but has not been consumed by the application.
Note: This is Linux-specific, using fflush()
on input streams is undefined by the standard, however, most implementations behave the same as in Linux.
I improved the script from AlexMA for showing my webcam on a web page wich periodically uploads a new image with the same name. I had issues that sometimes the image was flickering because of a broken image or not complete (up)loaded image. To prevent flickering I check the natural height of the image because the size of my webcam image did not change. Only if the loaded image height fits the original image height the full image will be shown on page.
<h3>Webcam</h3>
<p align="center">
<img id="webcam" title="Webcam" onload="updateImage();" src="https://www.your-domain.com/webcam/current.jpg" alt="webcam image" width="900" border="0" />
<script type="text/javascript" language="JavaScript">
// off-screen image to preload next image
var newImage = new Image();
newImage.src = "https://www.your-domain.com/webcam/current.jpg";
// remember the image height to prevent showing broken images
var height = newImage.naturalHeight;
function updateImage()
{
// for sure if the first image was a broken image
if(newImage.naturalHeight > height)
{
height = newImage.naturalHeight;
}
// off-screen image loaded and the image was not broken
if(newImage.complete && newImage.naturalHeight == height)
{
// show the preloaded image on page
document.getElementById("webcam").src = newImage.src;
}
// preload next image with cachebreaker
newImage.src = "https://www.your-domain.com/webcam/current.jpg?time=" + new Date().getTime();
// refresh image (set the refresh interval to half of webcam refresh,
// in my case the webcam refreshes every 5 seconds)
setTimeout(updateImage, 2500);

If you want to get string representations of MyEnum
variables, then templates won't cut it. Template can be specialized on integral values known at compile-time.
However, if that's what you want then try:
#include <iostream>
enum MyEnum { VAL1, VAL2 };
template<MyEnum n> struct StrMyEnum {
static char const* name() { return "Unknown"; }
};
#define STRENUM(val, str) \
template<> struct StrMyEnum<val> { \
static char const* name() { return str; }};
STRENUM(VAL1, "Value 1");
STRENUM(VAL2, "Value 2");
int main() {
std::cout << StrMyEnum<VAL2>::name();
}
This is verbose, but will catch errors like the one you made in question - your case VAL1
is duplicated.

If you have a plist of devices (eg maintained by @Tib above in https://stackoverflow.com/a/17655825/849616) to handle it if Swift 3 you'd use:
extension UIDevice {
/// Fetches the information about the name of the device.
///
/// - Returns: Should return meaningful device name, if not found will return device system code.
public static func modelName() -> String {
let physicalName = deviceSystemCode()
if let deviceTypes = deviceTypes(), let modelName = deviceTypes[physicalName] as? String {
return modelName
}
return physicalName
}
}
private extension UIDevice {
/// Fetches from system the code of the device
static func deviceSystemCode() -> String {
var systemInfo = utsname()
uname(&systemInfo)
let machineMirror = Mirror(reflecting: systemInfo.machine)
let identifier = machineMirror.children.reduce("") { identifier, element in
guard let value = element.value as? Int8, value != 0 else { return identifier }
return identifier + String(UnicodeScalar(UInt8(value)))
}
return identifier
}
/// Fetches the plist entries from plist maintained in https://stackoverflow.com/a/17655825/849616
///
/// - Returns: A dictionary with pairs of deviceSystemCode <-> meaningfulDeviceName.
static func deviceTypes() -> NSDictionary? {
if let fileUrl = Bundle.main.url(forResource: "your plist name", withExtension: "plist"),
let configurationDictionary = NSDictionary(contentsOf: fileUrl) {
return configurationDictionary
}
return nil
}
}
Later you can call it using UIDevice.modelName()
.
Additional credits go to @Tib (for plist), @Aniruddh Joshi (for deviceSystemCode()
function).
There are, as i recall, two distributions of the gnu toolchain for windows: mingw and cygwin.
I'd expect cygwin work - a lot of effort has been made to make that a "stadard" posix environment.
The mingw toolchain uses msvcrt.dll for its runtime and thus will probably expose msvcrt's "thread" api: _beginthread which is defined in <process.h>
I use serializable classes for the WCF communication between different modules. Below is an example of serializable class which serves as DataContract as well. My approach is to use the power of LINQ to convert the Dictionary into out-of-the-box serializable List<> of KeyValuePair<>:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.Xml.Serialization;
namespace MyFirm.Common.Data
{
[DataContract]
[Serializable]
public class SerializableClassX
{
// since the Dictionary<> class is not serializable,
// we convert it to the List<KeyValuePair<>>
[XmlIgnore]
public Dictionary<string, int> DictionaryX
{
get
{
return SerializableList == null ?
null :
SerializableList.ToDictionary(item => item.Key, item => item.Value);
}
set
{
SerializableList = value == null ?
null :
value.ToList();
}
}
[DataMember]
[XmlArray("SerializableList")]
[XmlArrayItem("Pair")]
public List<KeyValuePair<string, int>> SerializableList { get; set; }
}
}
The usage is straightforward - I assign a dictionary to my data object's dictionary field - DictionaryX. The serialization is supported inside the SerializableClassX by conversion of the assigned dictionary into the serializable List<> of KeyValuePair<>:
// create my data object
SerializableClassX SerializableObj = new SerializableClassX(param);
// this will call the DictionaryX.set and convert the '
// new Dictionary into SerializableList
SerializableObj.DictionaryX = new Dictionary<string, int>
{
{"Key1", 1},
{"Key2", 2},
};
There is no need for jQuery here, regular JavaScript will do:
var str = "Abc: Lorem ipsum sit amet";
str = str.substring(str.indexOf(":") + 1);
Or, the .split()
and .pop()
version:
var str = "Abc: Lorem ipsum sit amet";
str = str.split(":").pop();
Or, the regex version (several variants of this):
var str = "Abc: Lorem ipsum sit amet";
str = /:(.+)/.exec(str)[1];
A few ideas:
HEAD
command instead of a full GET to see if it needs to download the full file again, and the server uses the timestamp to see.If you want to disable caching on your server, you can do something like:
Header set Expires "Thu, 19 Nov 1981 08:52:00 GM"
Header set Cache-Control "no-store, no-cache, must-revalidate, post-check=0, pre-check=0"
Header set Pragma "no-cache"
In .htaccess
style = window.getComputedStyle(your_element);
then simply: style.height

You're trying to call an instance method on the class. To call an instance method on a class you must create an instance on which to call the method. If you want to call the method on non-instances add the static keyword. For example
class Example {
public static string NonInstanceMethod() {
return "static";
}
public string InstanceMethod() {
return "non-static";
}
}
static void SomeMethod() {
Console.WriteLine(Example.NonInstanceMethod());
Console.WriteLine(Example.InstanceMethod()); // Does not compile
Example v1 = new Example();
Console.WriteLine(v1.InstanceMethod());
}
still alloca use is discouraged, why?
I don't perceive such a consensus. Lots of strong pros; a few cons:
while
or for
loop) or in several scopes, the memory accumulates per iteration/scope and is not released until the function exits: this contrasts with normal variables defined in the scope of a control structure (e.g. for {int i = 0; i < 2; ++i) { X }
would accumulate alloca
-ed memory requested at X, but memory for a fixed-sized array would be recycled per iteration).inline
functions that call alloca
, but if you force them then the alloca
will happen in the callers' context (i.e. the stack won't be released until the caller returns)alloca
transitioned from a non-portable feature/hack to a Standardised extension, but some negative perception may persistmalloc
's explicit controlmalloc
encourages thinking about the deallocation - if that's managed through a wrapper function (e.g. WonderfulObject_DestructorFree(ptr)
), then the function provides a point for implementation clean up operations (like closing file descriptors, freeing internal pointers or doing some logging) without explicit changes to client code: sometimes it's a nice model to adopt consistently
WonderfulObject* p = WonderfulObject_AllocConstructor();
- that's possible when the "constructor" is a function returning malloc
-ed memory (as the memory remains allocated after the function returns the value to be stored in p
), but not if the "constructor" uses alloca
WonderfulObject_AllocConstructor
could achieve this, but "macros are evil" in that they can conflict with each other and non-macro code and create unintended substitutions and consequent difficult-to-diagnose problemsfree
operations can be detected by ValGrind, Purify etc. but missing "destructor" calls can't always be detected at all - one very tenuous benefit in terms of enforcement of intended usage; some alloca()
implementations (such as GCC's) use an inlined macro for alloca()
, so runtime substitution of a memory-usage diagnostic library isn't possible the way it is for malloc
/realloc
/free
(e.g. electric fence)On many systems alloca() cannot be used inside the list of arguments of a function call, because the stack space reserved by alloca() would appear on the stack in the middle of the space for the function arguments.
I know this question is tagged C, but as a C++ programmer I thought I'd use C++ to illustrate the potential utility of alloca
: the code below (and here at ideone) creates a vector tracking differently sized polymorphic types that are stack allocated (with lifetime tied to function return) rather than heap allocated.
#include <alloca.h>
#include <iostream>
#include <vector>
struct Base
{
virtual ~Base() { }
virtual int to_int() const = 0;
};
struct Integer : Base
{
Integer(int n) : n_(n) { }
int to_int() const { return n_; }
int n_;
};
struct Double : Base
{
Double(double n) : n_(n) { }
int to_int() const { return -n_; }
double n_;
};
inline Base* factory(double d) __attribute__((always_inline));
inline Base* factory(double d)
{
if ((double)(int)d != d)
return new (alloca(sizeof(Double))) Double(d);
else
return new (alloca(sizeof(Integer))) Integer(d);
}
int main()
{
std::vector<Base*> numbers;
numbers.push_back(factory(29.3));
numbers.push_back(factory(29));
numbers.push_back(factory(7.1));
numbers.push_back(factory(2));
numbers.push_back(factory(231.0));
for (std::vector<Base*>::const_iterator i = numbers.begin();
i != numbers.end(); ++i)
{
std::cout << *i << ' ' << (*i)->to_int() << '\n';
(*i)->~Base(); // optionally / else Undefined Behaviour iff the
// program depends on side effects of destructor
}
}
Do not create separate lists; create a list of lists:
results = []
with open('inputfile.txt') as inputfile:
for line in inputfile:
results.append(line.strip().split(','))
or better still, use the csv
module:
import csv
results = []
with open('inputfile.txt', newline='') as inputfile:
for row in csv.reader(inputfile):
results.append(row)
Lists or dictionaries are far superiour structures to keep track of an arbitrary number of things read from a file.
Note that either loop also lets you address the rows of data individually without having to read all the contents of the file into memory either; instead of using results.append()
just process that line right there.
Just for completeness sake, here's the one-liner compact version to read in a CSV file into a list in one go:
import csv
with open('inputfile.txt', newline='') as inputfile:
results = list(csv.reader(inputfile))
I think you would want to add an 'onSelect' event handler to the initialization of your datepicker so your code gets triggered when the user selects a date. Try it out on jsFiddle
$(document).ready(function(){

inline: true,
minDate: new Date(2010, 1 - 1, 1),
maxDate:new Date(2010, 12 - 1, 31),
altField: '#datepicker_value',
onSelect: function(){
var day1 = $("#datepicker").datepicker('getDate').getDate();

I had this issue recently. In my case, I had my IDE set to choose which compiler (C or C++) to use on each file according to its extension, and I was trying to call a C function (i.e. from a .c
file) from C++ code.
The .h
file for the C function wasn't wrapped in this sort of guard:
#ifdef __cplusplus
extern "C" {
#endif
// all of your legacy C code here
#ifdef __cplusplus
}
#endif
I could've added that, but I didn't want to modify it, so I just included it in my C++ file like so:
extern "C" {
#include "legacy_C_header.h"
}
(Hat tip to UncaAlby for his clear explanation of the effect of extern "C".)
Another way of doing this is using nested IF statements. Suppose you have companies table and you want to count number of records in it. A sample query would be something like this
SELECT IF(
count(*) > 15,
'good',
IF(
count(*) > 10,
'average',
'poor'
)
) as data_count
FROM companies
Here second IF condition works when the first IF condition fails. So Sample Syntax of the IF statement would be IF ( CONDITION, THEN, ELSE). Hope it helps someone.
Please be advised:
JSONP supports only the GET request method.
*Send request by firefox:*
$.ajax({
type: 'POST',//<<===
contentType: 'application/json',
url: url,
dataType: "json"//<<=============
...
});
Above request send by OPTIONS(while ==>type: 'POST')!!!!
$.ajax({

But above request send by GET(while ==>type: 'POST')!!!!
When you are in "cross-domain communication" , pay attention and be careful.
var x = $('#container')[0].outerHTML;
Press Ctrl + T on the method name (rather than F3). This gives the type hierarchy as a pop-up so is slightly faster than using F4 and the type hierarchy view.
Also, when done on a method, subtypes that don't implement/override the method will be greyed out, and when you double click on a class in the list it will take you straight to the method in that class.
When distribute to App Store, you choose Product -> Achieve and encounter "code sign error, no matching provisioning profiles found", if account and downloaded .mobileprovision file is ok. Try click the "Build and Run" button to run it on your phone.
And, a dialog box will popup with a button "Fix", just click "Fix" to do next... Last, your device will have an valid provisioning file. Just do "Product -> Achieve" again, everything is OK!
os.system
is equivalent to Unix system
command, while subprocess
was a helper module created to provide many of the facilities provided by the Popen
commands with an easier and controllable interface. Those were designed similar to the Unix Popen command.
system()
executes a command specified in command by calling/bin/sh -c command
, and returns after the command has been completed
Whereas:
The
popen()
function opens a process by creating a pipe, forking, and invoking the shell.
If you are thinking which one to use, then use subprocess
definitely because you have all the facilities for execution, plus additional control over the process.
I use this bit of code to import sql statements created by mysqldump:
public static void importSQL(Connection conn, InputStream in) throws SQLException
{
Scanner s = new Scanner(in);
s.useDelimiter("(;(\r)?\n)|(--\n)");
Statement st = null;
try
{
st = conn.createStatement();
while (s.hasNext())
{
String line = s.next();
if (line.startsWith("/*!") && line.endsWith("*/"))
{
int i = line.indexOf(' ');
line = line.substring(i + 1, line.length() - " */".length());
}
if (line.trim().length() > 0)
{
st.execute(line);
}
}
}
finally
{
if (st != null) st.close();
}
}
string Name = "Very good nice one is very good but is very good nice one this is called the term";
bool valid=true;
int count = 0;
int k=0;
int m = 0;
while (valid)
{
k = Name.Substring(m,Name.Length-m).IndexOf("good");
if (k != -1)
{
count++;
m = m + k + 4;
}
else
valid = false;
}
Console.WriteLine(count + " Times accures");
<?php
$input = array("Neo", "Morpheus", "Trinity", "Cypher", "Tank");

?>
git reset --hard HEAD~1
git push -f <remote> <branch>
(Example push: git push -f origin bugfix/bug123
)
This will undo the last commit and push the updated history to the remote. You need to pass the -f
because you're replacing upstream history in the remote.
You almost had it with Not
. It should be:
if (-Not (Test-Path C:\Code)) {
write "it doesn't exist!"
}
You can also use !
: if (!(Test-Path C:\Code)){}
Just for fun, you could also use bitwise exclusive or, though it's not the most readable/understandable method.
if ((test-path C:\code) -bxor 1) {write "it doesn't exist!"}
With ireport 4.7.1, after setting jdkhome in etc/ireport.conf
, ireport.exe
doesn't start. No splash, no window.
When I launch ireport_w.exe
in a cmd, I get this message:
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Solution:
In file etc/ireport.conf, on the line starting with default_options, I have reduced the value of -J-XX:MaxPermSize
to 256m instead of 512m
default_options="--branding ireport -J-Xms256m -J-Xmx512m
-J-Dorg.netbeans.ProxyClassLoader.level=1000 -J-XX:MaxPermSize=256m"
You can get all post data into this function :-
$postData = $request->post();
and if you want specific filed then use it :-
$request->post('current-password');
Relying on column order is generally a bad idea in SQL. SQL is based on Relational theory where order is never guaranteed - by design. You should treat all your columns and rows as having no order and then change your queries to provide the correct results:
For Columns:
For Rows:
Hope this helps...
So, let me give you sample code:
<div class="news">
Blah, blah, blah. I'm hidden.
</div>
<a class="trigger">Hide/Show News</a>
The link will be the trigger to show the div when clicked. So your Javascript will be:
$('.trigger').click(function() {
$('.news').toggle();
});
You're almost always better off letting jQuery handle the styling for hiding and showing elements.
Edit: I see people above are recommending using .show
and .hide
for this. .toggle
allows you to do both with just one effect. So that's cool.
The python error says that wordInput
is not an iterable -> it is of NoneType.
If you print wordInput
before the offending line, you will see that wordInput
is None
.
Since wordInput
is None
, that means that the argument passed to the function is also None
. In this case word
. You assign the result of pickEasy
to word
.
The problem is that your pickEasy
function does not return anything. In Python, a method that didn't return anything returns a NoneType.
I think you wanted to return a word
, so this will suffice:
def pickEasy():
word = random.choice(easyWords)
word = str(word)
for i in range(1, len(word) + 1):
wordCount.append("_")
return word
You can call [aDictionary description], or anywhere you would need a format string, just use %@ to stand in for the dictionary:
[NSString stringWithFormat:@"my dictionary is %@", aDictionary];
or
NSLog(@"My dictionary is %@", aDictionary);
You can use serialize()
like this:
$.ajax({
cache: false,
url: 'test.php',
data: $('form').serialize(),
datatype: 'json',
success: function(data) {
}
});
If the object implements IDisposable
, then yes, you should dispose it. The object could be hanging on to native resources (file handles, OS objects) that might not be freed immediately otherwise. This can lead to resource starvation, file-locking issues, and other subtle bugs that could otherwise be avoided.
See also Implementing a Dispose Method on MSDN.
With Lodash you can create a template and you can do that following way:
<div class="container">
<div class="row justify-content-center">
<div class="col-12">
<table id="tblEntAttributes" class="table">
<tbody>
<tr>
<td>
chkboxId
</td>
<td>
chkboxValue
</td>
<td>
displayName
</td>
<td>
logicalName
</td>
<td>
dataType
</td>
</tr>
</tbody>
</table>
<button class="btn btn-primary" id="test">appendTo</button>
</div>
</div>
</div>
And here goes the javascript:
var count = 1;
window.addEventListener('load', function () {
var compiledRow = _.template("<tr><td><input type=\"checkbox\" id=\"<%= chkboxId %>\" value=\"<%= chkboxValue %>\"></td><td><%= displayName %></td><td><%= logicalName %></td><td><%= dataType %></td><td><input type=\"checkbox\" id=\"chkAllPrimaryAttrs\" name=\"chkAllPrimaryAttrs\" value=\"chkAllPrimaryAttrs\"></td><td><input type=\"checkbox\" id=\"chkAllPrimaryAttrs\" name=\"chkAllPrimaryAttrs\" value=\"chkAllPrimaryAttrs\"></td></tr>");
document.getElementById('test').addEventListener('click', function (e) {
var ajaxData = { 'chkboxId': 'chkboxId-' + count, 'chkboxValue': 'chkboxValue-' + count, 'displayName': 'displayName-' + count, 'logicalName': 'logicalName-' + count, 'dataType': 'dataType-' + count };
var tableRowData = compiledRow(ajaxData);
$("#tblEntAttributes tbody").append(tableRowData);
count++;
});
});
Here it is in jsbin
html
<input id="something" onkeyup="key_up(this)" type="text">
script
function key_up(e){
var enterKey = 13; //Key Code for Enter Key
if (e.which == enterKey){
//Do you work here
}
}
Next time, Please try providing some code.
Strings are compared lexicographically using the numeric equivalents (the result of the built-in function ord()) of their characters. Unicode and 8-bit strings are fully interoperable in this behavior.
LESS has guard expressions for mixins, not individual attributes.
So you'd create a mixin like this:
.debug(@debug) when (@debug = true) {
header {
background-color: yellow;
#title {
background-color: orange;
}
}
article {
background-color: red;
}
}
And turn it on or off by calling .debug(true);
or .debug(false)
(or not calling it at all).
Create a .reg file containing your proxy settings for your users. Create a batch file setting it to setting it to run the .reg file with the extension /s
On a server using a logon script, tell the logon to run the batch file. Jason
You could also grab the attributes with the getAttribute() method which will return the value of a specific HTML attribute.
var elem = document.getElementById('the-span');_x000D_
_x000D_
var typeId = elem.getAttribute('data-typeId');_x000D_
var type = elem.getAttribute('data-type');_x000D_
var points = elem.getAttribute('data-points');_x000D_
var important = elem.getAttribute('data-important');_x000D_
_x000D_
console.log(`typeId: ${typeId} | type: ${type} | points: ${points} | important: ${important}`_x000D_
);
_x000D_
<span data-typeId="123" data-type="topic" data-points="-1" data-important="true" id="the-span"></span>
_x000D_
You could use CAST or CONVERT:
SELECT CAST(MyVarcharCol AS INT) FROM Table
SELECT CONVERT(INT, MyVarcharCol) FROM Table
You just need to wrap it around a String object like this:
String numberString = String(n);
You can also do:
String stringOne = "Hello String"; // using a constant String
String stringOne = String('a'); // converting a constant char into a String
String stringTwo = String("This is a string"); // converting a constant string into a String object
String stringOne = String(stringTwo + " with more"); // concatenating two strings
String stringOne = String(13); // using a constant integer
String stringOne = String(analogRead(0), DEC); // using an int and a base
String stringOne = String(45, HEX); // using an int and a base (hexadecimal)
String stringOne = String(255, BIN); // using an int and a base (binary)
String stringOne = String(millis(), DEC); // using a long and a base
I decided to post an answer on how to do that exact same thing without jQuery. Just because I'm a rebel.
var ageCheckbox = document.getElementById('isAgeSelected');
var ageInput = document.getElementById('txtAge');
// Just because of IE <333
ageCheckbox.onchange = function() {
// Check if the checkbox is checked, and show/hide the text field.
ageInput.hidden = this.checked ? false : true;
};
First you get both elements by their ID. Then you assign the checkboxe's onchange
event a function that checks whether the checkbox got checked and sets the hidden
property of the age text field appropriately. In that example using the ternary operator.
Here is a fiddle for you to test it.
Addendum
If cross-browser compatibility is an issue then I propose to set the CSS display
property to none and inline.
elem.style.display = this.checked ? 'inline' : 'none';
Slower but cross-browser compatible.
Swift 3 solution:
let languages = ["bs", "zh-Hant", "en", "fi", "ko", "lv", "ms", "pl", "pt-BR", "ru", "sr-Latn", "sk", "es", "tr"]
UserDefaults.standard.set([languages[0]], forKey: "AppleLanguages")
Gave some examples of language codes that can be used. Hope this helps
If you want to get the ASCII value of a character, or just convert it into an int, you need to cast from a char to an int.
What's casting? Casting is when we explicitly convert from one primitve data type, or a class, to another. Here's a brief example.
public class char_to_int
{
public static void main(String args[])
{
char myChar = 'a';
int i = (int) myChar; // cast from a char to an int
System.out.println ("ASCII value - " + i);
}
In this example, we have a character ('a'), and we cast it to an integer. Printing this integer out will give us the ASCII value of 'a'.
I was facing this issue in Grafana and all I had to do was go to the config file and change allow_embedding to true and restart the server :)
The new way to do with c++20 is using format.
#include <format>
auto var = std::format("sometext {} sometext {}", somevar, somevar);
Would this solution work?:
add following line to SceneDelegate: window.rootViewController?.view.backgroundColor = .black
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
if let windowScene = scene as? UIWindowScene {
window.rootViewController?.view.backgroundColor = .black
}
This is an old bug, but I encountered it today on a web service which had barely been altered since being created via "New \ Project.."
For me, this issue was caused by the "IService.cs
" file containing the following:
<%@ ServiceHost Language="C#" Debug="true" Service="JSONWebService.Service1.svc" CodeBehind="Service1.svc.cs" %>
Notice the value in the Service
attribute contains ".svc
" at the end.
This shouldn't be there.
Removing those 4 characters resolved this issue.
<%@ ServiceHost Language="C#" Debug="true" Service="JSONWebService.Service1" CodeBehind="Service1.svc.cs" %>
Note that you need to open this file from outside of Visual Studio.
Visual Studio shows one file, Service1.cs
in the Solution Explorer, but that only lets you alter Service1.svc.cs
, not the Service1.svc
file.
I did it like this
#!/bin/bash
ZK_HOST="localhost"
ZK_PORT=2181
for i in `echo dump | nc $ZK_HOST $ZK_PORT | grep brokers`
do
echo $i
DETAIL=`zkCli -server "$ZK_HOST:$ZK_PORT" get $i 2>/dev/null | tail -n 1`

A good example of using ids of other rows in the same table as foreign keys is nested lists.
Deleting a row that has children (i.e., rows, which refer to parent's id), which also have children (i.e., referencing ids of children) will delete a cascade of rows.
This will save a lot of pain (and a lot of code of what to do with orphans - i.e., rows, that refer to non-existing ids).
You could also use the store library which performs it for you with crossbrowser ability.
example :
// Store current user
store.set('user', { name:'Marcus' })
// Get current user
store.get('user')
// Remove current user
store.remove('user')
// Clear all keys
store.clearAll()
// Loop over all stored values
store.each(function(value, key) {
console.log(key, '==', value)
})
A note for anyone who is coming from a backend or Django based role and trying to work with ReactJS: No one manages to setup ReactJS enviroment successfully in the first try :)
There is a blog from Owais Lone which is available from http://owaislone.org/blog/webpack-plus-reactjs-and-django/ ; however syntax on Webpack configuration is way out of date.
I suggest you follow the steps mentioned in the blog and replace the webpack configuration file with the content below. However if you're new to both Django and React, chew one at a time because of the learning curve you will probably get frustrated.

There is also the _reindex
option
From documentation:
Through the Elasticsearch reindex API, available in version 5.x and later, you can connect your new Elasticsearch Service deployment remotely to your old Elasticsearch cluster. This pulls the data from your old cluster and indexes it into your new one. Reindexing essentially rebuilds the index from scratch and it can be more resource intensive to run.
POST _reindex
{
"source": {
"remote": {
"host": "https://REMOTE_ELASTICSEARCH_ENDPOINT:PORT",
"username": "USER",
"password": "PASSWORD"
},
"index": "INDEX_NAME",
"query": {
"match_all": {}
}
},
"dest": {
"index": "INDEX_NAME"
}
}
Use the ToDictionary
method directly.
var result =
// as Jon Skeet pointed out, OrderBy is useless here, I just leave it
// show how to use OrderBy in a LINQ query
myClassCollection.OrderBy(mc => mc.SomePropToSortOn)
.ToDictionary(mc => mc.KeyProp.ToString(),
mc => mc.ValueProp.ToString(),
StringComparer.OrdinalIgnoreCase);
You missed the each=
argument to rep()
:
R> n <- 3
R> rep(1:5, each=n)
[1] 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5
R>
so your example can be done with a simple
R> rep(1:8, each=20)
You can use jsoup or wffweb (HTML5) based.
Sample code for jsoup:-
Document doc = Jsoup.parse("<html></html>");
doc.body().addClass("body-styles-cls");
doc.body().appendElement("div");
System.out.println(doc.toString());
prints
<html>
<head></head>
<body class=" body-styles-cls">
<div></div>
</body>
</html>
Sample code for wffweb:-
Html html = new Html(null) {{
new Head(this);
new Body(this,
new ClassAttribute("body-styles-cls"));
}};
Body body = TagRepository.findOneTagAssignableToTag(Body.class, html);
body.appendChild(new Div(null));
System.out.println(html.toHtmlString());
//directly writes to file
html.toOutputStream(new FileOutputStream("/home/user/filepath/filename.html"), "UTF-8");
prints (in minified format):-
<html>
<head></head>
<body class="body-styles-cls">
<div></div>
</body>
</html>
Still I wonder if there's a more convenient way of finding index of en element without caching (or there's a good caching technique that will boost up the performance).
You can use binary search (if your array is ordered and the values you store in the array are comparable in some way). For that to work you need to be able to tell the binary search whether it should be looking "to the left" or "to the right" of the current element. But I believe there is nothing wrong with storing the index
at insertion time and then using it if you are getting the element from the same array.
Try this
IsBodyHtml = false,
BodyEncoding = Encoding.UTF8,
BodyTransferEncoding = System.Net.Mime.TransferEncoding.EightBit
If you wish to stick to using \r\n
I managed to get mine working after trying for one whole day!
I'm using jersey 2.0 with message body readers and writers. I had my method return type as a specific entity which was also used in the implementation of the message body writer and i was returning the same pojo, a SkuListDTO. @GET @Consumes({"application/xml", "application/json"}) @Produces({"application/xml", "application/json"}) @Path("/skuResync")
public SkuResultListDTO getSkuData()
....
return SkuResultListDTO;
all i changed was this, I left the writer implementation alone and it still worked.
public Response getSkuData()
...
return Response.status(Response.Status.FORBIDDEN).entity(dfCoreResultListDTO).build();
Why not use relative units?
