Explicit conversion constructors (C++ only)
The explicit function specifier controls unwanted implicit type conversions. It can only be used in declarations of constructors within a class declaration. For example, except for the default constructor, the constructors in the following class are conversion constructors.
class A
{
public:
A();
A(int);
A(const char*, int = 0);
};
The following declarations are legal:
A c = 1;
A d = "Venditti";
The first declaration is equivalent to A c = A( 1 );
.
If you declare the constructor of the class as explicit
, the previous declarations would be illegal.
For example, if you declare the class as:
class A
{
public:
explicit A();
explicit A(int);
explicit A(const char*, int = 0);
};
You can only assign values that match the values of the class type.
For example, the following statements are legal:
A a1;
A a2 = A(1);
A a3(1);
A a4 = A("Venditti");
A* p = new A(1);
A a5 = (A)1;
A a6 = static_cast<A>(1);
This means that the folder/file that you are trying to put on svn already exists there. My advice is that before doing anything just right click on the folder/file and click on repo-browser. By doing this you will be able to see all the files/sub-folders etc that are already present on svn. If the required file/folder is not present on the svn then you just delete(after taking backup) the file that you you want to add and then run an update.

The ^

SELECT * FROM mytable WHERE REGEXP_LIKE(column_1, '[^A-Za-z]')
Could you try this one:
create or replace

LOOP
dbms_output.put_line(thisteam.FIRSTNAME|| ' ' || thisteam.LASTNAME || ':' || thisteam.S);
END LOOP;
END;
Check your X Window environment variables using the "env" command.
Then there is always Rosetta Code, which shows crc32 implemented in dozens of computer languages. https://rosettacode.org/wiki/CRC-32 and has links to many explanations and implementations.
Spring MockMvc now has direct support for JSON. So you just say:
.andExpect(content().json("{'message':'ok'}"));
and unlike string comparison, it will say something like "missing field xyz" or "message Expected 'ok' got 'nok'.
This method was introduced in Spring 4.1.
When the number is not big, everything seems just right. But if it isn't, great caution is required to achieve correctness.
Take double as an example:
If it is not big, as others mentioned you can just try this simply:
doubles.stream().mapToDouble(d -> d).average().orElse(0.0);
However, if it's out of your control and quite big, you have to turn to BigDecimal as follows (methods in the old answers using BigDecimal actually are wrong).
doubles.stream().map(BigDecimal::valueOf).reduce(BigDecimal.ZERO, BigDecimal::add)
.divide(BigDecimal.valueOf(doubles.size())).doubleValue();
Enclose the tests I carried out to demonstrate my point:
@Test
public void testAvgDouble() {
assertEquals(5.0, getAvgBasic(Stream.of(2.0, 4.0, 6.0, 8.0)), 1E-5);
List<Double> doubleList = new ArrayList<>(Arrays.asList(Math.pow(10, 308), Math.pow(10, 308), Math.pow(10, 308), Math.pow(10, 308)));
// Double.MAX_VALUE = 1.7976931348623157e+308
BigDecimal doubleSum = BigDecimal.ZERO;
for (Double d : doubleList) {
doubleSum = doubleSum.add(new BigDecimal(d.toString()));
}
out.println(doubleSum.divide(valueOf(doubleList.size())).doubleValue());
out.println(getAvgUsingRealBigDecimal(doubleList.stream()));
out.println(getAvgBasic(doubleList.stream()));
out.println(getAvgUsingFakeBigDecimal(doubleList.stream()));
}
private double getAvgBasic(Stream<Double> doubleStream) {
return doubleStream.mapToDouble(d -> d).average().orElse(0.0);
}
private double getAvgUsingFakeBigDecimal(Stream<Double> doubleStream) {
return doubleStream.map(BigDecimal::valueOf)
.collect(Collectors.averagingDouble(BigDecimal::doubleValue));
}
private double getAvgUsingRealBigDecimal(Stream<Double> doubleStream) {
List<Double> doubles = doubleStream.collect(Collectors.toList());
return doubles.stream().map(BigDecimal::valueOf).reduce(BigDecimal.ZERO, BigDecimal::add)
.divide(valueOf(doubles.size()), BigDecimal.ROUND_DOWN).doubleValue();
}
As for Integer
or Long
, correspondingly you can use BigInteger
similarly.
None of these answers are working (date today 9th Dec 2018). The correct resolution here is to add .table-responsive-sm to your table:
<table class='table table-responsive-sm'>
[Your table]
</table>
This applies the responsiveness aspect only to the SM view (mobile). So in mobile view you get the scrolling as desired and in larger views the table is not responsive and thus displayed full width, as desired.

I had the same problem, to resolve it, go windows -> preferences -> servers and select runtime environment, and now you will see a new window, in the upper right you will see a option: Download additional server adapter, click and install the glassfish server.
Note that usage of a SerialPort.DataReceived
event is optional. You can set proper timeout using SerialPort.ReadTimeout
and continuously call SerialPort.Read()
after you wrote something to a port until you get a full response.
Moreover you can use SerialPort.BaseStream
property to extract an underlying Stream
instance. The benefit of using a Stream
is that you can easily utilize various decorators with it:
var port = new SerialPort();
// LoggingStream inherits Stream, implements IDisposable, needen abstract methods and
// overrides needen virtual methods.
Stream portStream = new LoggingStream(port.BaseStream);
portStream.Write(...); // Logs write buffer.
portStream.Read(...); // Logs read buffer.

I add the same situation and went in a couple of stackoverfow, github and tutorials showing complex solutions. Nothing simple though! Some with "Hold the alt key and move the mouse while the cursor shows a cross" which is not for laptop users (at least for me), some others with configuration files...
I found it after a good sleep night. My environment is laptop, ubuntu and Jupyter/Ipython 5.1.0 :
Just select/highlight one line, a block or something, and then "Ctrl"+"/" and it's magic :)

I've found lots of posts across the web on the various ways to do the request, but none that actually show how to process the response synchronously on AWS Lambda.
Here's a Node 6.10.3 lambda function that uses an https request, collects and returns the full body of the response, and passes control to an unlisted function processBody
with the results. I believe http and https are interchangable in this code.
I'm using the async utility module, which is easier to understand for newbies. You'll need to push that to your AWS Stack to use it (I recommend the serverless framework).
Note that the data comes back in chunks, which are gathered in a global variable, and finally the callback is called when the data has end
ed.
'use strict';
const async = require('async');
const https = require('https');
module.exports.handler = function (event, context, callback) {
let body = "";
let countChunks = 0;
async.waterfall([
requestDataFromFeed,
// processBody,
], (err, result) => {
if (err) {
console.log(err);
callback(err);
}
else {
const message = "Success";
console.log(result.body);
callback(null, message);
}
});
function requestDataFromFeed(callback) {
const url = 'https://put-your-feed-here.com';
console.log(`Sending GET request to ${url}`);
https.get(url, (response) => {
console.log('statusCode:', response.statusCode);
response.on('data', (chunk) => {
countChunks++;
body += chunk;
});
response.on('end', () => {
const result = {
countChunks: countChunks,
body: body
};
callback(null, result);
});
}).on('error', (err) => {
console.log(err);
callback(err);
});
}
};
In reguards to using jQuery to do hover, I always use the plugin HoverIntent as it doesn't fire the event until you pause over an element for brief period of time... this stops firing off lots of mouse over events if you accidentally run the mouse over them or simply whilst choosing an option.
There are a number of different options, based on what exactly the effect you're going for is. Chris Coyier did a piece on just this way back when. Worth a read:
Unless you really want to keep the dictionary, I think the best solution is to use the csv
Python module to read the file.
Then, you get rows of data and you can change member_phone
or whatever you want ;
finally, you can use the csv
module again to save the file in the same format
as you opened it.
Code for reading:
import csv
with open("my_input_file.txt", "r") as f:
reader = csv.reader(f, delimiter=":")
lines = list(reader)
Code for writing:
with open("my_output_file.txt", "w") as f:
writer = csv.writer(f, delimiter=":")
writer.writerows(lines)
Of course, you need to adapt your change()
function:
def change(lines):
a = input('ID')
for line in lines:
if line[0] == a:
d=str(input("phone"))
line[3]=d
break
else:
print "not"
Here is implementation of standard C++ 14 using vectors and tuples to Read and Write Text,Binary and Hex files

vec_buf = v_buf;
bin_file.close();
}

I've had a very similar issue using spring-boot-starter-data-redis
. To my implementation there was offered a @Bean
for RedisTemplate
as follows:
@Bean
public RedisTemplate<String, List<RoutePlantCache>> redisTemplate(RedisConnectionFactory connectionFactory) {
final RedisTemplate<String, List<RoutePlantCache>> template = new RedisTemplate<>();
template.setConnectionFactory(connectionFactory);
template.setKeySerializer(new StringRedisSerializer());
template.setValueSerializer(new Jackson2JsonRedisSerializer<>(RoutePlantCache.class));
// Add some specific configuration here. Key serializers, etc.
return template;
}
The fix was to specify an array of RoutePlantCache
as following:
template.setValueSerializer(new Jackson2JsonRedisSerializer<>(RoutePlantCache[].class));
Below the exception I had:
com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `[...].RoutePlantCache` out of START_ARRAY token

While yourTextField.requestFocus()
is A solution, it is not the best since in the official Java documentation this is discourage as the method requestFocus()
is platform dependent.
The documentation says:
Note that the use of this method is discouraged because its behavior is platform dependent. Instead we recommend the use of requestFocusInWindow().
Use yourJTextField.requestFocusInWindow()
instead.
If you mean you want to see them like this:
WORKPLACEID NAME ADDRESS TELEPHONE
----------- ---------- -------------- ---------
1 HSBC Nugegoda Road 43434
2 HNB Bank Colombo Road 223423
then in SQL Plus you can set the column widths like this (for example):
column name format a10
column address format a20
column telephone format 999999999
You can also specify the line size and page size if necessary like this:
set linesize 100 pagesize 50
You do this by typing those commands into SQL Plus before running the query. Or you can put these commands and the query into a script file e.g. myscript.sql and run that. For example:
column name format a10
column address format a20
column telephone format 999999999
select name, address, telephone
from mytable;
Internet Explorer 8 and older don't support the proper MIME type for XHTML, application/xhtml+xml
. If you're serving XHTML as text/html
, which you have to for these older versions of Internet Explorer to do anything, it will be interpreted as HTML 4.01. You can only use the short syntax with any element that permits the closing tag to be omitted. See the HTML 4.01 Specification.
The XML 'short form' is interpreted as an attribute named /, which (because there is no equals sign) is interpreted as having an implicit value of "/". This is strictly wrong in HTML 4.01 - undeclared attributes are not permitted - but browsers will ignore it.
IE9 and later support XHTML 5 served with application/xhtml+xml
.
Since assertThat
which was the old answer is now deprecated, I am posting the correct solution:
assertTrue(objectUnderTest instanceof TargetObject);
Both 'is' and 'as' are valid syntax. Output is disabled by default. Try a procedure that also enables output...
create or replace procedure temp_proc is
begin
DBMS_OUTPUT.ENABLE(1000000);
DBMS_OUTPUT.PUT_LINE('Test');
end;
...and call it in a PLSQL block...
begin
temp_proc;
end;
...as SQL is non-procedural.
As stated in the urllib2
documentation:
The
urllib2
module has been split across several modules in Python 3 namedurllib.request
andurllib.error
. The2to3
tool will automatically adapt imports when converting your sources to Python 3.
So you should instead be saying
from urllib.request import urlopen
html = urlopen("http://www.google.com/").read()
print(html)
Your current, now-edited code sample is incorrect because you are saying urllib.urlopen("http://www.google.com/")
instead of just urlopen("http://www.google.com/")
.
Sorry to bring up an old thread, but here is a little manual for those who (like me!) don't see how Eli Grey's example works:
var test = new Object();
test.watch("elem", function(prop,oldval,newval){
//Your code
return newval;
});
Hope this can help someone
You need to edit your PATH environmental variable to make sure wherever the homebrew python is located is searched before /usr/bin. You could also set things up in your shell config to have a variable like PYTHON be set to your desired version of python and call $PYTHON
rather than python
from the command line.
Also, as another poster stated (and especially on mac) DO NOT mess with the python in /usr/bin to point it to another python install. You're just asking for trouble if you do.

Strictly speaking, the answer is no. A developer cannot prevent a user from uploading files of any type or extension.
But still, the accept attribute of <input type = "file">
can help to provide a filter in the file select dialog box of the OS. For example,
<!-- (IE 10+, Edge (EdgeHTML), Edge (Chromium), Chrome, Firefox 42+) -->
<input type="file" accept=".xls,.xlsx" />
_x000D_
should provide a way to filter out files other than .xls or .xlsx. Although the MDN page for input
element always said that it supports this, to my surprise, this didn't work for me in Firefox until version 42. This works in IE 10+, Edge, and Chrome.
So, for supporting Firefox older than 42 along with IE 10+, Edge, Chrome, and Opera, I guess it's better to use comma-separated list of MIME-types:
<!-- (IE 10+, Edge (EdgeHTML), Edge (Chromium), Chrome, Firefox) -->
<input type="file"
accept="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet,application/vnd.ms-excel" />
_x000D_
[Edge (EdgeHTML) behavior: The file type filter dropdown shows the file types mentioned here, but is not the default in the dropdown. The default filter is All files (*)
.]
You can also use asterisks in MIME-types. For example:
<input type="file" accept="image/*" /> <!-- all image types -->
<input type="file" accept="audio/*" /> <!-- all audio types -->
<input type="file" accept="video/*" /> <!-- all video types -->
_x000D_
W3C recommends authors to specify both MIME-types and corresponding extensions in the accept
attribute. So, the best approach is:
<!-- Right approach: Use both file extensions and corresponding MIME-types. -->
<!-- (IE 10+, Edge (EdgeHTML), Edge (Chromium), Chrome, Firefox) -->
<input type="file"
accept=".xls,.xlsx, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet,application/vnd.ms-excel" />
_x000D_
JSFiddle of the same: here.
Reference: List of MIME-types
IMPORTANT: Using the accept
attribute only provides a way of filtering in the files of types that are of interest. Browsers still allow users to choose files of any type. Additional (client-side) checks should be done (using JavaScript, one way would be this), and definitely file types MUST be verified on the server, using a combination of MIME-type using both the file extension and its binary signature (ASP.NET, PHP, Ruby, Java). You might also want to refer to these tables for file types and their magic numbers, to perform a more robust server-side verification.
Here are three good reads on file-uploads and security.
EDIT: Maybe file type verification using its binary signature can also be done on client side using JavaScript (rather than just by looking at the extension) using HTML5 File API, but still, the file must be verified on the server, because a malicious user will still be able to upload files by making a custom HTTP request.
This is a simple example of what I used for a recent test. You need to make sure that your security settings are the same on the server and client.
var myBinding = new BasicHttpBinding();
myBinding.Security.Mode = BasicHttpSecurityMode.None;
var myEndpointAddress = new EndpointAddress("http://servername:8732/TestService/");
client = new ClientTest(myBinding, myEndpointAddress);
client.someCall();
Try this:
Function.prototype.extends = function(parent) {
this.prototype = Object.create(parent.prototype);
};
Monkey.extends(Monster);
function Monkey() {
Monster.apply(this, arguments); // call super
}
Edit: I put a quick demo here http://jsbin.com/anekew/1/edit. Note that extends
is a reserved word in JS and you may get warnings when linting your code, you can simply name it inherits
, that's what I usually do.
With this helper in place and using an object props
as only parameter, inheritance in JS becomes a bit simpler:
Function.prototype.inherits = function(parent) {
this.prototype = Object.create(parent.prototype);
};
function Monster(props) {
this.health = props.health || 100;
}
Monster.prototype = {
growl: function() {
return 'Grrrrr';
}
};
Monkey.inherits(Monster);
function Monkey() {
Monster.apply(this, arguments);
}
var monkey = new Monkey({ health: 200 });
console.log(monkey.health); //=> 200
console.log(monkey.growl()); //=> "Grrrr"
I came across this question as I was looking to install simplejson for Python 2.6. I needed to use the 'object_pairs_hook' of json.load() in order to load a json file as an OrderedDict. Being familiar with more recent versions of Python I didn't realize that the json module for Python 2.6 doesn't include the 'object_pairs_hook' so I had to install simplejson for this purpose. From personal experience this is why i use simplejson as opposed to the standard json module.
I dont know what do you exactly mean but hope it help you.
by this directive you can access the DOM element inside controller
this is sample that help you to focus element inside controller
.directive('scopeElement', function () {
return {
restrict:"A", // E-Element A-Attribute C-Class M-Comments
replace: false,
link: function($scope, elem, attrs) {
$scope[attrs.scopeElement] = elem[0];
}
};
})
now, inside HTML
<input scope-element="txtMessage" >
then, inside controller :
.controller('messageController', ['$scope', function ($scope) {
$scope.txtMessage.focus();
}])
In the comments @libjack mentioned a point which is really important. I would like to illustrate more into it. First, we can check what are the columns of our table by describe <table_name>;
command.
there is a double-column called _c1 and such columns are created by the hive itself when we moving data from one table to another. To address these columns we need to write it inside backticks
`_c1`
Finally, the ALTER command will be,
ALTER TABLE <table_namr> CHANGE `<system_genarated_column_name>` <new_column_name> <data_type>;
You need the python-dev
package which contains Python.h
When you generate a web reference and click on the web reference in the Solution Explorer. In the properties pane you should see something like this:
Changing the value to dynamic will put an entry in your app.config.
Here is the CodePlex article that has more information.
A more generic approach
To simplify this approach an "id" interface is used
public interface IGuidKey
{
Guid Id { get; set; }
}
The helper method
public static void Modify<T>(this DbSet<T> set, Guid id, Action<T> func)
where T : class, IGuidKey, new()
{
var target = new T
{
Id = id
};
var entry = set.Attach(target);
func(target);
foreach (var property in entry.Properties)
{
var original = property.OriginalValue;
var current = property.CurrentValue;
if (ReferenceEquals(original, current))
{
continue;
}
if (original == null)
{
property.IsModified = true;
continue;
}
var propertyIsModified = !original.Equals(current);
property.IsModified = propertyIsModified;
}
}
Usage
dbContext.Operations.Modify(id, x => { x.Title = "aaa"; });
I have been using smartassembly. Basically, you pick a dll and it returns it obfuscated. It seems to work fine and I've had no problems so far. Very, very easy to use.
You can use np.logaddexp
(which implements the idea in @gg349's answer):
In [33]: d = np.array([[1089, 1093]])
In [34]: e = np.array([[1000, 4443]])
In [35]: log_res = np.logaddexp(-3*d[0,0], -3*d[0,1]) - np.logaddexp(-3*e[0,0], -3*e[0,1])
In [36]: log_res
Out[36]: -266.99999385580668
In [37]: res = exp(log_res)
In [38]: res
Out[38]: 1.1050349147204485e-116
Or you can use scipy.special.logsumexp
:
In [52]: from scipy.special import logsumexp
In [53]: res = np.exp(logsumexp(-3*d) - logsumexp(-3*e))
In [54]: res
Out[54]: 1.1050349147204485e-116
it doesn't matter what type of value you wish to post, just enclose it within the quotation marks, to get it as string. Not for complex types.

myData = "some sentence";
$http.post(url, "'" + myData + "'")
.then(function (response) { console.log(response.data); });
myData = { name: 'person name', age: 21 };
$http.post(url, "'" + JSON.stringify(myData) + "'")

I have a more general answer; but I believe it is useful for counting the columns for all tables in a DB:
SELECT table_name, count(*)
FROM information_schema.columns
GROUP BY table_name;
To create elements with equal width using Flex
, you should set to your's child (flex elements):
flex-basis: 25%;
flex-grow: 0;
It will give to all elements in row 25% width. They will not grow and go one by one.
To build on JJC's helpful answer that builds on Louis's helpful answer...
With PhantomJS 2.1.1-windows this line works:
driver.execute_script("return navigator.userAgent")
If it doesn't work, you can still get the user agent via the log (to build on Mma's answer):
from selenium import webdriver
import json
from fake_useragent import UserAgent
dcap = dict(DesiredCapabilities.PHANTOMJS)
dcap["phantomjs.page.settings.userAgent"] = (UserAgent().random)
driver = webdriver.PhantomJS(executable_path=r"your_path", desired_capabilities=dcap)
har = json.loads(driver.get_log('har')[0]['message']) # get the log
print('user agent: ', har['log']['entries'][0]['request']['headers'][1]['value'])
I don't think answer from Vincent Malgrat is correct. When NVARCHAR2
was introduced long time ago nobody was even talking about Unicode.
Initially Oracle provided VARCHAR2
and NVARCHAR2
to support localization. Common data (include PL/SQL) was hold in VARCHAR2
, most likely US7ASCII
these days. Then you could apply NLS_NCHAR_CHARACTERSET
individually (e.g. WE8ISO8859P1
) for each of your customer in any country without touching the common part of your application.
Nowadays character set AL32UTF8
is the default which fully supports Unicode. In my opinion today there is no reason anymore to use NLS_NCHAR_CHARACTERSET
, i.e. NVARCHAR2
, NCHAR2
, NCLOB
. Note, there are more and more Oracle native functions which do not support NVARCHAR2, so you should really avoid it. Maybe the only reason is when you have to support mainly Asian characters where AL16UTF16
consumes less storage compared to AL32UTF8
.
It happened for me also and the reason was selecting inappropriate combination of tomcat and Dynamic web module version while creating project in eclipse. I selected Tomcat v9.0 along with Dynamic web module version 3.1 and eclipse was not able to resolve the HttpServlet type. When used Tomcat 7.0 along with Dynamic web module version 7.0, eclipse was automatically able to resolve the HttpServlet type.

To check which version of tomcat should be used along with different versions of the Servlet and JSP specifications refer http://tomcat.apache.org/whichversion.html
Here is the code to read the excel data by column.

If you want to modify only the first commit, you may try git rebase and amend the commit, which is similar to this post: How to modify a specified commit in git?
And if you want to modify all the commits which contain the raw email, filter-branch is the best choice. There is an example of how to change email address globally on the book Pro Git, and you may find this link useful http://git-scm.com/book/en/Git-Tools-Rewriting-History
This can also happen when the log file is restricted in size.

From What's the Difference between WCF and Web Services?
WCF is a replacement for all earlier web service technologies from Microsoft. It also does a lot more than what is traditionally considered as "web services".
WCF "web services" are part of a much broader spectrum of remote communication enabled through WCF. You will get a much higher degree of flexibility and portability doing things in WCF than through traditional ASMX because WCF is designed, from the ground up, to summarize all of the different distributed programming infrastructures offered by Microsoft. An endpoint in WCF can be communicated with just as easily over SOAP/XML as it can over TCP/binary and to change this medium is simply a configuration file mod. In theory, this reduces the amount of new code needed when porting or changing business needs, targets, etc.
ASMX is older than WCF, and anything ASMX can do so can WCF (and more). Basically you can see WCF as trying to logically group together all the different ways of getting two apps to communicate in the world of Microsoft; ASMX was just one of these many ways and so is now grouped under the WCF umbrella of capabilities.
Web Services can be accessed only over HTTP & it works in stateless environment, where WCF is flexible because its services can be hosted in different types of applications. Common scenarios for hosting WCF services are IIS,WAS, Self-hosting, Managed Windows Service.
The major difference is that Web Services Use
XmlSerializer
. But WCF UsesDataContractSerializer
which is better in performance as compared toXmlSerializer
.
You may do this with a for
loop instead of a while
:
max_loop=20
for ((count = 0; count < max_loop; count++)); do
if /home/hadoop/latest/bin/hadoop fs -ls /apps/hdtech/bds/quality-rt/dt=$DATE_YEST_FORMAT2 then
echo "Files Present" | mailx -s "File Present" -r [email protected] [email protected]
break
else
echo "Sleeping for half an hour" | mailx -s "Time to Sleep Now" -r [email protected] [email protected]
sleep 1800
fi
done
if [ "$count" -eq "$max_loop" ]; then
echo "Maximum number of trials reached" >&2
exit 1
fi

I realize that this is an old question, but I'll post the solution for my use case, in case others run into the same situation I did when implementing James Hill's answer (above).
I found this question while trying to solve the same issue. James' answer got me 90% there. However, for my use case, selecting the item from the dropdown also triggered an action on the page from dropdown's onchange
event. James' code as written did not trigger this event (at least in Firefox, which I was testing in). As a result, I made the following minor change:
function setSelectedValue(object, value) {
for (var i = 0; i < object.options.length; i++) {
if (object.options[i].text === value) {
object.options[i].selected = true;
object.onchange();
return;
}
}
// Throw exception if option `value` not found.
var tag = object.nodeName;
var str = "Option '" + value + "' not found";
if (object.id != '') {
str = str + " in //" + object.nodeName.toLowerCase()
+ "[@id='" + object.id + "']."
}
else if (object.name != '') {
str = str + " in //" + object.nodeName.toLowerCase()
+ "[@name='" + object.name + "']."
}
else {
str += "."
}
throw str;
}
Note the object.onchange()
call, which I added to the original solution. This calls the handler to make certain that the action on the page occurs.
Added code to throw an exception if option value
is not found; this is needed for my use case.
mode1.name()
or String.valueOf(mode1)
. It doesn't get better than that, I'm afraid
Use DATE(NOW())
to compare dates
DATE(NOW())
will give you the date part of current date and DATE(duedate)
will give you the date part of the due date. then you can easily compare the dates
So you can compare it like
DATE(NOW()) = DATE(duedate)
OR
DATE(duedate) = CURDATE()
See here
Try:
mmatrix = np.zeros((nrows, ncols))
Since the shape parameter has to be an int or sequence of ints
http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html
Otherwise you are passing ncols
to np.zeros
as the dtype.
I'm currently using this function:
function array_delete($del_val, $array) {
if(is_array($del_val)) {
foreach ($del_val as $del_key => $del_value) {
foreach ($array as $key => $value){
if ($value == $del_value) {
unset($array[$key]);
}
}
}
} else {
foreach ($array as $key => $value){
if ($value == $del_val) {
unset($array[$key]);
}
}
}
return array_values($array);
}
You can input an array or only a string with the element(s) which should be removed. Write it like this:
$detils = array('apple', 'orange', 'strawberry', 'blueberry', 'kiwi');
$detils = array_delete(array('orange', 'apple'), $detils);
OR
$detils = array_delete('orange', $detils);
It'll also reindex it.
Calling .parents(".box .something1")
will return all parent elements that match the selector .box .something
. In other words, it will return parent elements that are .something1
and are inside of .box
.
You need to get the children of the closest parent, like this:
$(this).closest('.box').children('.something1')
This code calls .closest
to get the innermost parent matching a selector, then calls .children
on that parent element to find the uncle you're looking for.
the shortest code is :
JLabel jLabelObject = new JLabel();
jLabelObject.setIcon(new ImageIcon(stringPictureURL));
stringPictureURL is PATH of image .
For s: When used with printf functions, specifies a single-byte or multi-byte character string; when used with wprintf functions, specifies a wide-character string. Characters are displayed up to the first null character or until the precision value is reached.
For S: When used with printf functions, specifies a wide-character string; when used with wprintf functions, specifies a single-byte or multi-byte character string. Characters are displayed up to the first null character or until the precision value is reached.
In Unix-like platform, s and S have the same meaning as windows platform.

The settings for Decimal
are its precision and scale or in normal language, how many digits can a number have and how many digits do you want to have to the right of the decimal point.
So if you put PI
into a Decimal(18,0)
it will be recorded as 3
?
If you put PI
into a Decimal(18,2)
it will be recorded as 3.14
?
If you put PI
into Decimal(18,10)
be recorded as 3.1415926535

You have to add a MySQL jdbc driver to the classpath.

git blame -L 10,+1 fe25b6d^ -- src/options.cpp
You can specify a revision for git blame to look back starting from (instead of the default of HEAD
); fe25b6d^
is the parent of fe25b6d
.
Edit: New to Git 2.23, we have the --ignore-rev
option added to git blame
:
git blame --ignore-rev fe25b6d
While this doesn't answer OP's question of giving the stack of commits (you'll use git log
for that, as per the other answer), it is a better way of this solution, as you won't potentially misblame the other lines.
Old question but i feel i should add the following, even more because .net 4.0 had already launched at the time the question was written.
Starting with .net 4.0 there is the namespace System.Collections.Concurrent
which includes collections that are thread-safe.
The collection System.Collections.Concurrent.ConcurrentDictionary<>
does exactly what you want. It has the AddOrUpdate()
method with the added advantage of being thread-safe.
If you're in a high-performance scenario and not handling multiple threads the already given answers of map[key] = value
are faster.
In most scenarios this performance benefit is insignificant. If so i'd advise to use the ConcurrentDictionary because:
Just try this code:
start "" "C:\Users\DiPesh\Desktop\vbscript\welcome.vbs"

$ kill 31139
str.strip()

You can probably add two foreign key constraints (honestly: I've never tried it), but it'd then insist the parent row exist in both tables.
Instead you probably want to create a supertype for your two employee subtypes, and then point the foreign key there instead. (Assuming you have a good reason to split the two types of employees, of course).
employee
employees_ce ———————— employees_sn
———————————— type ————————————
empid —————————> empid <——————— empid
name /|\ name
|
|
deductions |
—————————— |
empid ————————+
name
type
in the employee table would be ce
or sn

Please Remember if you want to install python package/libraries for windows,
you should always consider Python unofficial Binaries
Step 1:
Search for your package, download dependent version 2.7 or 3.6 you can find it under Downloads/your_package_version.whl its called python wheel
Step 2:
Now install using pip,
pip install ~/Downloads/your_packae_ver.whl
this will install without any error.
I would definitely avoid any answers involving hard-coded values, as the actual margins may change with user font-size settings, etc.
Here is @user1687195's answer, written without modifying the textContainer.lineFragmentPadding
(because the docs state this is not the intended usage).
This works great for iOS 7 and later.
self.textView.textContainerInset = UIEdgeInsetsMake(
0,
-self.textView.textContainer.lineFragmentPadding,
0,
-self.textView.textContainer.lineFragmentPadding);
This is effectively the same outcome, just a bit cleaner in that it doesn't misuse the lineFragmentPadding property.

Problem solved!
I was having all my website set up first in XAMMP, then I had to transfer it to LAMP, in a SUSE installation of LAMP, where I got this error.
The problem is that these parameters in the database.php file should not be initialised. Just leave username and password blank. That's just it.
(My first and lame guess would be that's because of old version of mysql, as built-in installations come with older versions.
The solution at my end was to explicitly add a JoinColumn annotation like this:
@JoinColumn(name="mapping_type_id")
The column name is usually the table name + "_id" if there is an id field. Additionally, keep in mind which field it should be based on the relationship, OneToMany or ManyToOne.
Hope this helps.
Your logic condition is wrong. IIUC, what you want is:
import pyspark.sql.functions as f
df.filter((f.col('d')<5))\
.filter(
((f.col('col1') != f.col('col3')) |
(f.col('col2') != f.col('col4')) & (f.col('col1') == f.col('col3')))
)\
.show()
I broke the filter()
step into 2 calls for readability, but you could equivalently do it in one line.
Output:
+----+----+----+----+---+
|col1|col2|col3|col4| d|
+----+----+----+----+---+
| A| xx| D| vv| 4|
| A| x| A| xx| 3|
| E| xxx| B| vv| 3|
| F|xxxx| F| vvv| 4|
| G| xxx| G| xx| 4|
+----+----+----+----+---+
In case someone else stumbles onto this topic - here's a more "one size fits all" solution.
If you are using .git
or .svn
, you can use the --exclude-vcs
option for tar. This will ignore many different files/folders required by different version control systems.
If you want to read more about it, check out: http://www.gnu.org/software/tar/manual/html_section/exclude.html
A one liner to drop all tables from a given database:
echo "DATABASE_NAME"| xargs -I{} sh -c "mysql -Nse 'show tables' {}| xargs -I[] mysql -e 'SET FOREIGN_KEY_CHECKS=0; drop table []' {}"
Running this will drop all tables from database DATABASE_NAME.
And a nice thing about this is that the database name is only written explicitly once.
Like this.
.divContainer input[type="text"] {
width:150px;
}
.divContainer input[type="radio"] {
width:20px;
}
Let's say you would like to pass the string Dev
as a parameter, from your batch file:
powershell -command "G:\Karan\PowerShell_Scripts\START_DEV.ps1 Dev"
put inside your powershell script head:
$w = $args[0] # $w would be set to "Dev"
This if you want to use the built-in variable $args
. Otherwise:
powershell -command "G:\Karan\PowerShell_Scripts\START_DEV.ps1 -Environment \"Dev\""
and inside your powershell script head:
param([string]$Environment)
This if you want a named parameter.
You might also be interested in returning the error level:
powershell -command "G:\Karan\PowerShell_Scripts\START_DEV.ps1 Dev; exit $LASTEXITCODE"
The error level will be available inside the batch file as %errorlevel%
.
You can use the .charAt(int) function with Strings to retrieve the char value at any index. If you want to convert the String to a char array, try calling .toCharArray() on the String.
String g = "line";
char c = g.charAt(0); // returns 'l'
char[] c_arr = g.toCharArray(); // returns a length 4 char array ['l','i','n','e']
We don't need to plt.ioff()
or plt.show()
(if we use %matplotlib inline
). You can test above code without plt.ioff()
. plt.close()
has the essential role. Try this one:
%matplotlib inline
import pylab as plt
# It doesn't matter you add line below. You can even replace it by 'plt.ion()', but you will see no changes.
## plt.ioff()
# Create a new figure, plot into it, then close it so it never gets displayed
fig = plt.figure()
plt.plot([1,2,3])
plt.savefig('test0.png')
plt.close(fig)
# Create a new figure, plot into it, then don't close it so it does get displayed
fig2 = plt.figure()
plt.plot([1,3,2])
plt.savefig('test1.png')
If you run this code in iPython, it will display a second plot, and if you add plt.close(fig2)
to the end of it, you will see nothing.
In conclusion, if you close figure by plt.close(fig)
, it won't be displayed.

For the bug
Undefined symbols for architecture i386:
A somewhat better solution:
atexit([] { system("PAUSE"); });
at the beginning of your program.
Pros:
cin.sync(); cin.ignore();
trick instead of system("pause");
)Cons:
extern "C" int __stdcall IsDebuggerPresent(void);
int main(int argc, char** argv) {
if (IsDebuggerPresent())
atexit([] {system("PAUSE"); });
...
}
It's the Substring method of String
, with the first argument set to 0.
myString.Substring(0,1);
[The following was added by Almo; see Justin J Stark's comment. —Peter O.]
Warning:
If the string's length is less than the number of characters you're taking, you'll get an ArgumentOutOfRangeException
.
If empName is a VARCHAR(50) column:
ALTER TABLE Employees MODIFY COLUMN empName VARCHAR(50) AFTER department;
EDIT
Per the comments, you can also do this:
ALTER TABLE Employees CHANGE COLUMN empName empName VARCHAR(50) AFTER department;
Note that the repetition of empName
is deliberate. You have to tell MySQL that you want to keep the same column name.
You should be aware that both syntax versions are specific to MySQL. They won't work, for example, in PostgreSQL or many other DBMSs.
Another edit: As pointed out by @Luis Rossi in a comment, you need to completely specify the altered column definition just before the AFTER
modifier. The above examples just have VARCHAR(50)
, but if you need other characteristics (such as NOT NULL
or a default value) you need to include those as well. Consult the docs on ALTER TABLE
for more info.
You must create them under strings.xml
<string name="close">Close</string>
You must replace and reference like this
android:text="@string/close"/>
Do not use @strings even though the XML file says strings.xml or else it will not work.
You can also do it this way:
byte[] getBytes (File file)
{
FileInputStream input = null;
if (file.exists()) try
{
input = new FileInputStream (file);
int len = (int) file.length();
byte[] data = new byte[len];
int count, total = 0;
while ((count = input.read (data, total, len - total)) > 0) total += count;
return data;
}
catch (Exception ex)
{
ex.printStackTrace();
}
finally
{
if (input != null) try
{
input.close();
}
catch (Exception ex)
{
ex.printStackTrace();
}
}
return null;
}
When you open a folder in VSCode, it will automatically scan the folder for typical project artifacts like project.json or solution files. From the status bar in the lower left side you can switch between solutions and projects.
Also check if the resource-name contains any illegal characters (for me it was a "-" in my-image)

Addendum: "mm" in the format String is not the same as "MM". Use MM for months and mm for minutes. Also, yyyyy is not the same as yyyy. e.g.,:
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class FormateDate {
public static void main(String[] args) throws ParseException {
String date_s = "2011-01-18 00:00:00.0";
// *** note that it's "yyyy-MM-dd hh:mm:ss" not "yyyy-mm-dd hh:mm:ss"
SimpleDateFormat dt = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
Date date = dt.parse(date_s);
// *** same for the format String below
SimpleDateFormat dt1 = new SimpleDateFormat("yyyy-MM-dd");
System.out.println(dt1.format(date));
}
}
You could also create the input button in this way:
var button = '<input type="button" id="questionButton" value='+variable+'> <br />';
It might be the syntax of the Button creation that is off somehow.
So am I assuming correctly that uid is a Unique Identifier (Guid)? Is this just an example of a possible scenario or are you really trying to find a guid that matches an array of strings?
If this is true you may want to really rethink this whole approach, this seems like a really bad idea. You should probably be trying to match a Guid to a Guid
Guid id = new Guid(uid);
var query = from xx in table
where xx.uid == id
select xx;
I honestly can't imagine a scenario where matching a string array using "contains" to the contents of a Guid would be a good idea. For one thing, Contains() will not guarantee the order of numbers in the Guid so you could potentially match multiple items. Not to mention comparing guids this way would be way slower than just doing it directly.
Firstly, your URL definition does not accept any parameters at all. If you want parameters to be passed from the URL into the view, you need to define them in the urlconf.
Secondly, it's not at all clear what you are expecting to happen to the cleaned_data dictionary. Don't forget you can't redirect to a POST - this is a limitation of HTTP, not Django - so your cleaned_data either needs to be a URL parameter (horrible) or, slightly better, a series of GET parameters - so the URL would be in the form:
/link/mybackend/?field1=value1&field2=value2&field3=value3
and so on. In this case, field1, field2 and field3 are not included in the URLconf definition - they are available in the view via request.GET
.
So your urlconf would be:
url(r'^link/(?P<backend>\w+?)/$', my_function)
and the view would look like:
def my_function(request, backend):
data = request.GET
and the reverse would be (after importing urllib
):
return "%s?%s" % (redirect('my_function', args=(backend,)),
urllib.urlencode(form.cleaned_data))
Edited after comment
The whole point of using redirect and reverse, as you have been doing, is that you go to the URL - it returns an Http code that causes the browser to redirect to the new URL, and call that.
If you simply want to call the view from within your code, just do it directly - no need to use reverse at all.
That said, if all you want to do is store the data, then just put it in the session:
request.session['temp_data'] = form.cleaned_data
What can we build with NodeJS:
try this
html
<div ng-controller="MyCtrl">
Hello, {{newDate | date:'MM/dd/yyyy'}}!
</div>
JS
var myApp = angular.module('myApp',[]);
function MyCtrl($scope) {
var collectionDate = '2002-04-26T09:00:00';
$scope.newDate =new Date(collectionDate);
}
try this
$.getJSON(url, function(data){
$.each(data.response.venue.tips.groups.items, function (index, value) {
console.log(this.text);
});
});
Vinay (above) gave an effective work-around. What's actually causing the button's OnClick event to not work following the OnClientClick event function is that MS has defined it where, once the button is disabled (in the function called by the OnClientClick event), the button "honors" this by not trying to complete the button's activity by calling the OnClick event's defined method.
I struggled several hours trying to figure this out. Once I removed the statement to disable the submit button (that was inside the OnClientClick function), the OnClick method was called with no further problem.
Microsoft, if you're listening, once the button is clicked it should complete it's assigned activity even if it is disabled part of the way through this activity. As long as it is not disabled when it is clicked, it should complete all assigned methods.
Below are the two option you can use
return default(T);
or
where T : class, IThing
return null;
If all your values are unique, you can make a reverse dictionary:
PIXO_reverse = {v: k for k, v in PIX0.items()}
Result:
>>> PIXO_reverse
{'320x240': 'QVGA', '640x480': 'VGA', '800x600': 'SVGA'}
Now you can use the same logic as before.
You can solve the problem by checking if your date matches a REGEX pattern. If not, then NULL (or something else you prefer).
In my particular case it was necessary because I have >20 DATE columns saved as CHAR, so I don't know from which column the error is coming from.
Returning to your query:
1. Declare a REGEX pattern.
It is usually a very long string which will certainly pollute your code (you may want to reuse it as well).
define REGEX_DATE = "'your regex pattern goes here'"
Don't forget a single quote inside a double quote around your Regex :-)
A comprehensive thread about Regex date validation you'll find here.
2. Use it as the first CASE condition:
To use Regex validation in the SELECT
statement, you cannot use REGEXP_LIKE
(it's only valid in WHERE
. It took me a long time to understand why my code was not working. So it's certainly worth a note.
Instead, use REGEXP_INSTR
For entries not found in the pattern (your case) use REGEXP_INSTR (variable, pattern) = 0
.
DEFINE REGEX_DATE = "'your regex pattern goes here'"
SELECT c.contract_num,
CASE
WHEN REGEXP_INSTR(c.event_dt, ®EX_DATE) = 0 THEN NULL
WHEN ( MAX (TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))
- MIN (TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD')))
/ COUNT (c.event_occurrence) < 32
THEN
'Monthly'
WHEN ( MAX (
TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))
- MIN (
TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD')))
/ COUNT (c.event_occurrence) >= 32
AND ( MAX (
TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))
- MIN (
TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD')))
/ COUNT (c.event_occurrence) < 91
THEN
'Quarterley'
ELSE
'Yearly'
END
FROM ps_ca_bp_events c

You use new
to perform dynamic allocation. It returns a pointer that points to the dynamically allocated object.
You have no reason to use new
, since A
is an automatic variable. You can simply initialise A
using its constructor:
vector<vector<int> > A(dimension, vector<int>(dimension));
You can convert yourInt
to bytes by using a ByteBuffer
like this:
return ByteBuffer.allocate(4).putInt(yourInt).array();
Beware that you might have to think about the byte order when doing so.
I don't like absolute positioning, either, because there is almost always some collateral damage, i.e. unintended side effects. Especially when you are working with a responsive design. There seems to be an alternative - the sandbag technique. By inserting a "helper" element, either in the markup of via CSS, we can push elements down to the bottom of the container. See http://community.sitepoint.com/t/css-floating-divs-to-the-bottom-inside-a-div/20932 for examples.
I have had the same error. And after I have already thought my mind is broken, because I had rename almost all my models properties the solution was delete one reference on All Syncfusion Controls and add references to the individual controls of this controls. (From Nuget)
Try:
var date = new Date('2012-11-29 17:00:34 UTC');
date.toString();
If you don't have a common way to atomically update or insert (e.g., via a transaction) then you can fallback to another locking scheme. A 0-byte file, system mutex, named pipe, etc...
You are mixing the 2 different CASE
syntaxes inappropriately.
Use this style (Searched)
CASE
WHEN u.nnmu ='0' THEN mu.naziv_mesta
WHEN u.nnmu ='1' THEN m.naziv_mesta
ELSE 'GRESKA'
END as mesto_utovara,
Or this style (Simple)
CASE u.nnmu
WHEN '0' THEN mu.naziv_mesta
WHEN '1' THEN m.naziv_mesta
ELSE 'GRESKA'
END as mesto_utovara,
Not This (Simple but with boolean search predicates)
CASE u.nnmu
WHEN u.nnmu ='0' THEN mu.naziv_mesta
WHEN u.nnmu ='1' THEN m.naziv_mesta
ELSE 'GRESKA'
END as mesto_utovara,
In MySQL this will end up testing whether u.nnmu
is equal to the value of the boolean expression u.nnmu ='0'
itself. Regardless of whether u.nnmu
is 1
or 0
the result of the case expression itself will be 1
For example if nmu = '0'
then (nnmu ='0'
) evaluates as true
(1) and (nnmu ='1'
) evaluates as false
(0). Substituting these into the case expression gives
SELECT CASE '0'
WHEN 1 THEN '0'
WHEN 0 THEN '1'
ELSE 'GRESKA'
END as mesto_utovara
if nmu = '1'
then (nnmu ='0'
) evaluates as false
(0) and (nnmu ='1'
) evaluates as true
(1). Substituting these into the case expression gives
SELECT CASE '1'
WHEN 0 THEN '0'
WHEN 1 THEN '1'
ELSE 'GRESKA'
END as mesto_utovara
I have done a very simple thing to enable or disable command button. Below is my grid

<HeaderStyle />
<AlternatingRowStyle />
<Columns>
<asp:BoundField DataField="ProductSKU" ReadOnly="true" HeaderText="Product SKU" HeaderStyle-CssClass="headTb4" />
<asp:BoundField DataField="ProductName" ReadOnly="true" HeaderText="ProductName" HeaderStyle-CssClass="headTb4" />

<ItemStyle HorizontalAlign="Center" />
</asp:CommandField>
</Columns>
<AlternatingRowStyle CssClass="odd" />
<PagerStyle HorizontalAlign="Center" VerticalAlign="Top" Wrap="False" />
In the following method i have done the changes
protected void grdOrderProduct_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
foreach (ImageButton button in e.Row.Cells[5].Controls.OfType<ImageButton>())
{
if (button.CommandName == "Delete")
{
button.Visible = false;
}
}
}
}
You can use islower()
on your string to see if it contains some lowercase letters (amongst other characters). or
it with isupper()
to also check if contains some uppercase letters:
below: letters in the string: test yields true
>>> z = "(555) 555 - 5555 ext. 5555"
>>> z.isupper() or z.islower()
True
below: no letters in the string: test yields false.
>>> z= "(555).555-5555"
>>> z.isupper() or z.islower()
False
>>>
Not to be mixed up with isalpha()
which returns True
only if all characters are letters, which isn't what you want.
Note that Barm's answer completes mine nicely, since mine doesn't handle the mixed case well.
You have to understand that Python represents all its data as objects. Some of these objects like lists and dictionaries are mutable, meaning you can change their content without changing their identity. Other objects like integers, floats, strings and tuples are objects that can not be changed. An easy way to understand that is if you have a look at an objects ID.
Below you see a string that is immutable. You can not change its content. It will raise a TypeError
if you try to change it. Also, if we assign new content, a new object is created instead of the contents being modified.
>>> s = "abc"
>>>id(s)
4702124
>>> s[0]
'a'
>>> s[0] = "o"
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'str' object does not support item assignment
>>> s = "xyz"
>>>id(s)
4800100
>>> s += "uvw"
>>>id(s)
4800500
You can do that with a list and it will not change the objects identity
>>> i = [1,2,3]
>>>id(i)
2146718700
>>> i[0]
1
>>> i[0] = 7
>>> id(i)
2146718700
To read more about Python's data model you could have a look at the Python language reference:
A combination of TRANSCRIPT_MODE_ALWAYS_SCROLL and setSelection made it work for me
ChatAdapter adapter = new ChatAdapter(this);
ListView lv = (ListView) findViewById(R.id.chatList);
lv.setTranscriptMode(AbsListView.TRANSCRIPT_MODE_ALWAYS_SCROLL);
lv.setAdapter(adapter);
adapter.registerDataSetObserver(new DataSetObserver() {
@Override
public void onChanged() {
super.onChanged();
lv.setSelection(adapter.getCount() - 1);
}
});
This is better way
let new_row = document.createElement('div');
new_row.setAttribute("class", "classname");
new_row.setAttribute("id", "idname");

You have it almost done. The logic is correct, just some little changes.
This code checks for the existence of the folder (see the ending backslash, just to differentiate a folder from a file with the same name).
If it does not exist then it is created and creation status is checked. If a file with the same name exists or you have no rights to create the folder, it will fail.
If everyting is ok, files are copied.
All paths are quoted to avoid problems with spaces.
It can be simplified (just less code, it does not mean it is better). Another option is to always try to create the folder. If there are no errors, then copy the files
mkdir "%USERPROFILE%\.qgis-custom" 2>nul
if not errorlevel 1 (
xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)
In both code samples, files are not copied if the folder is not being created during the script execution.
EDITED - As dbenham comments, the same code can be written as a single line
md "%USERPROFILE%\.qgis-custom" 2>nul && xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
The code after the &&
will only be executed if the previous command does not set errorlevel. If mkdir
fails, xcopy
is not executed.
If you use the SQLite DB-Browser you can change the default value in this way:
I recommend to make an update of your database before, because a wrong format in the value can lead to problems in the SQLLite Browser.
mutable
does exist as you infer to allow one to modify data in an otherwise constant function.
The intent is that you might have a function that "does nothing" to the internal state of the object, and so you mark the function const
, but you might really need to modify some of the objects state in ways that don't affect its correct functionality.
The keyword may act as a hint to the compiler -- a theoretical compiler could place a constant object (such as a global) in memory that was marked read-only. The presence of mutable
hints that this should not be done.
Here are some valid reasons to declare and use mutable data:
mutable boost::mutex
is perfectly reasonable.You could also use plac (a wrapper around argparse
).
As a bonus it generates neat help instructions - see below.
#!/usr/bin/env python3

arg: ('Argument with two possible values', 'positional', None, None, ['A', 'B'])

The name of the argument usually equals the parameter name (arg
).
The tuple annotation after arg

Argument with two possible values
)positional
)None

)['A', 'B']
)To learn more about using plac check out its great documentation:
One way is to use ANSI escape sequences:
import sys
import time
for i in range(10):
print("Loading" + "." * i)
sys.stdout.write("\033[F") # Cursor up one line
time.sleep(1)
Also sometimes useful (for example if you print something shorter than before):
sys.stdout.write("\033[K") # Clear to the end of line
Test with [char]9, such as:
$Tab = [char]9
Write-Output "$Tab hello"
Output:
hello
What about char.IsDigit(myChar)
?
You could try my Beavertail ADSI browser - it should show you the current AD tree, and from it, you should be able to figure out the path and all.
Or if you're on .NET 3.5, using the System.DirectoryServices.AccountManagement
namespace, you could also do it programmatically:
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
This would create a basic, default domain context and you should be able to peek at its properties and find a lot of stuff from it.
Or:
UserPrincipal myself = UserPrincipal.Current;
This will give you a UserPrincipal
object for yourself, again, with a ton of properties to inspect. I'm not 100% sure what you're looking for - but you most likely will be able to find it on the context or the user principal somewhere!
try using:

The instructions by peter_budo worked perfectly. I had to add the jars under /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home/jre/lib/ to my IntelliJ project libraries. Now it works like a charm. Note that I didn't need my IDE itself to run under 1.7; rather, I only needed to be able to compile and run against 1.7. I'll most likely continue to use Apple's JRE for running the IDE since it's probably more stable with respect to graphics routines (Swing, AWT). Like the OP, I was really keen on testing out the new NIO2 API. Looking good so far. Thanks, Peter.
This definitely works if the iframe is from the same domain as your parent site. I have not tested it for cross-domain sites.
$(window.frames['YouriFrameId']).click(function(event){ /* do something here */ });
$(window.frames['YouriFrameId']).mousedown(function(event){ /* do something here */ });
$(window.frames['YouriFrameId']).mouseup(function(event){ /* do something here */ });
Without jQuery you could try something like this, but again I have not tried this.
window.frames['YouriFrameId'].onmousedown = function() { do something here }
You can even filter your results:
$(window.frames['YouriFrameId']).mousedown(function(event){
var eventId = $(event.target).attr('id');
if (eventId == 'the-id-you-want') {
// do something
}
});
If it is in inline context, in HTML try this:
onclick="functionCall();event.stopPropagation();
If you also want it to be a command you can reference without remembering the arguments, you could simply alias it:
alias df-gb='df -BG'
So if you type:
df-gb
into a terminal, you'll get your intended output of the disk usage in GB.
EDIT: or even use just df -h
to get it in a standard, human readable format.
Declare an array of strings in C++ like this : char array_of_strings[][]
For example : char array_of_strings[200][8192];
will hold 200 strings, each string having the size 8kb or 8192 bytes.
use strcpy(line[i],tempBuffer);
to put data in the array of strings.
I'm still new in C++ development. I started with Visual Studio (VS).
Yet, no one seems to mentioned the __interface
in VS (.NET). I am not very sure if this is a good way to declare an interface. But it seems to provide an additional enforcement (mentioned in the documents). Such that you don't have to explicitly specify the virtual TYPE Method() = 0;
, since it will be automatically converted.
__interface IMyInterface {
HRESULT CommitX();
HRESULT get_X(BSTR* pbstrName);
};
However, I don't use it because I am concern about the cross platform compilation compatibility, since it only available under .NET.
If anyone do have anything interesting about it, please share. :-)
Thanks.
For zooming your map two level then just add this small code of line
map.setZoom(map.getZoom() + 2);
The command history is an interactive feature. Only complete commands are entered in the history. For example, the case
construct is entered as a whole, when the shell has finished parsing it. Neither looking up the history with the history
built-in (nor printing it through shell expansion (!:p
)) does what you seem to want, which is to print invocations of simple commands.
The DEBUG
trap lets you execute a command right before any simple command execution. A string version of the command to execute (with words separated by spaces) is available in the BASH_COMMAND
variable.
trap 'previous_command=$this_command; this_command=$BASH_COMMAND' DEBUG
…
echo "last command is $previous_command"
Note that previous_command
will change every time you run a command, so save it to a variable in order to use it. If you want to know the previous command's return status as well, save both in a single command.
cmd=$previous_command ret=$?
if [ $ret -ne 0 ]; then echo "$cmd failed with error code $ret"; fi
Furthermore, if you only want to abort on a failed commands, use set -e
to make your script exit on the first failed command. You can display the last command from the EXIT
trap.
set -e
trap 'echo "exit $? due to $previous_command"' EXIT
Note that if you're trying to trace your script to see what it's doing, forget all this and use set -x
.
I used this code to show the dialog at the bottom of the screen:
Dialog dlg = <code to create custom dialog>;
Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();
wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);
This code also prevents android from dimming the background of the dialog, if you need it. You should be able to change the gravity parameter to move the dialog about
private void showPictureialog() {
final Dialog dialog = new Dialog(this,
android.R.style.Theme_Translucent_NoTitleBar);
// Setting dialogview
Window window = dialog.getWindow();
window.setGravity(Gravity.CENTER);
window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
dialog.setTitle(null);
dialog.setContentView(R.layout.selectpic_dialog);
dialog.setCancelable(true);
dialog.show();
}
you can customize you dialog based on gravity and layout parameters change gravity and layout parameter on the basis of your requirenment
image
has a shape of (64,64,3)
.
Your input placeholder _x
have a shape of (?, 64,64,3)
.
The problem is that you're feeding the placeholder with a value of a different shape.
You have to feed it with a value of (1, 64, 64, 3)
= a batch of 1 image.
Just reshape your image
value to a batch with size one.
image = array(img).reshape(1, 64,64,3)
P.S: the fact that the input placeholder accepts a batch of images, means that you can run predicions for a batch of images in parallel.
You can try to read more than 1 image (N images) and than build a batch of N image, using a tensor with shape (N, 64,64,3)
In my case I was launching a WKWebView and displaying a website. Then (within 25 seconds) I deallocated the WKWebView. But 25-60 seconds after launching the WKWebView I received this "113" error message. I assume the system was trying to signal something to the WKWebView and couldn't find it because it was deallocated.
The fix was simply to leave the WKWebView allocated.
For future visitors: In the new HttpClient
(Angular 4.3+), the response
object is JSON by default, so you don't need to do response.json().data
anymore. Just use response
directly.
Example (modified from the official documentation):
import { HttpClient } from '@angular/common/http';
@Component(...)
export class YourComponent implements OnInit {
// Inject HttpClient into your component or service.
constructor(private http: HttpClient) {}
ngOnInit(): void {
this.http.get('https://api.github.com/users')
.subscribe(response => console.log(response));

Don't forget to import it and include the module under imports in your project's app.module.ts:

@NgModule({

// Include it under 'imports' in your application module after BrowserModule.
HttpClientModule,
...
],

There are several ways.
awk has a system()
function that will run a shell command:
system("cmd")
You can print to a pipe:
print "blah" | "cmd"
You can have awk construct commands, and pipe all the output to the shell:
awk 'some script' | sh
If the script does its job (relatively) well, then it's running okay. Your problem is probably a single line in the file referencing a program that's either not on the path, not installed, misspelled, or something similar.
One way is to place a set -x
at the top of your script or run it with bash -x
instead of just bash
- this will output the lines before executing them and you usually just need to look at the command output immediately before the error to see what's causing the problem
If, as you say, it's the blank lines causing the problems, you might want to check what's actaully in them. Run:
od -xcb testscript.sh
and make sure there's no "invisible" funny characters like the CTRL-M
(carriage return) you may get by using a Windows-type editor.
Convert your JSON object to JSON String using
JSON.stringify({"name":"testName"})

Ólafur forgot the surrogate key:
A surrogate key in a database is a unique identifier for either an entity in the modeled world or an object in the database. The surrogate key is not derived from application data.
Given that you are using a stateless component as a arrow function the content needs to get in parenthesis "()" instead of brackets "{}" and you have to remove the return function.
const Search_Bar= () => (
<input />;
);
Check to make sure that both score and array[x] are numerical types. You might be comparing an integer to a string...which is heartbreakingly possible in Python 2.x.
>>> 2 < "2"
True
>>> 2 > "2"
False
>>> 2 == "2"
False
Edit
Further explanation: How does Python compare string and int?
When you select a radio button and click on a submit button, you need to handle the submission of any selected values in your php code using $_POST[]
For example:
if your radio button is:
<input type="radio" name="rdb" value="male"/>
then in your php code you need to use:
$rdb_value = $_POST['rdb'];
change
public class LinqHelper
to
public static class LinqHelper
Following points need to be considered when creating an extension method:
non-generic
, static
and non-nested
static
methodthis
keyword. It's most strongly dependent on the package distribution system you use. For example, with MacPorts, you can install multiple Python packages and use the pyselect
utility to switch the default between them with ease. At all times, you're able to call the different Python interpreters by providing the full path, and you're able to link against all the Python libraries and headers by providing the full paths for those.
So basically, whatever way you install the versions, as long as you keep your installations separate, you'll able to run them separately.
I made this work in this way:
<button class="btn" ng-click='toggleClass($event)'>button one</button>
<button class="btn" ng-click='toggleClass($event)'>button two</button>
in your controller:
$scope.toggleClass = function (event) {
$(event.target).toggleClass('active');
}
You can restart the database on RDS Admin.

truncate -s 10G foo
fallocate -l 5G bar
It needs to be stated that truncate
on a file system supporting sparse files will create a sparse file and fallocate
will not. A sparse file is one where the allocation units that make up the file are not actually allocated until used. The meta-data for the file will however take up some considerable space but likely no where near the actual size of the file. You should consult resources about sparse files for more information as there are advantages and disadvantages to this type of file. A non-sparse file has its blocks (allocation units) allocated ahead of time which means the space is reserved as far as the file system sees it. Also fallocate
nor truncate
will not set the contents of the file to a specified value like dd
, instead the contents of a file allocated with fallocate
or truncate
may be any trash value that existed in the allocated units during creation and this behavior may or may not be desired. The dd
is the slowest because it actually writes the value or chunk of data to the entire file stream as specified with it's command line options.
This behavior could potentially be different - depending on file system used and conformance of that file system to any standard or specification. Therefore it is advised that proper research is done to ensure that the appropriate method is used.
For a combobox (http://en.wikipedia.org/wiki/Combo_box) which allows free text input and has a dropdown listbox I used a AutoCompleteTextView
as suggested by vbence.
I used the onClickListener
to display the dropdown list box when the user selects the control.
I believe this resembles this kind of a combobox best.
private static final String[] STUFF = new String[] { "Thing 1", "Thing 2" };
public void onCreate(Bundle b) {
final AutoCompleteTextView view =
(AutoCompleteTextView) findViewById(R.id.myAutoCompleteTextView);
view.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
view.showDropDown();
}
});
final ArrayAdapter<String> adapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_dropdown_item_1line,
STUFF
);
view.setAdapter(adapter);
}
Try This code:
public class GenericCompare<T> : IEqualityComparer<T> where T : class
{
private Func<T, object> _expr { get; set; }
public GenericCompare(Func<T, object> expr)
{
this._expr = expr;
}
public bool Equals(T x, T y)
{
var first = _expr.Invoke(x);
var sec = _expr.Invoke(y);
if (first != null && first.Equals(sec))
return true;
else
return false;
}
public int GetHashCode(T obj)
{
return obj.GetHashCode();
}
}
Example of its use would be
collection = collection
.Except(ExistedDataEles, new GenericCompare<DataEle>(x=>x.Id))
.ToList();
In my case, I tried xcode-select --install
but it says that it's not available from the store. Then, inspired by Rimian, I checked my gcc : gcc -v
and then I got a message saying I did not aggreed.
From that point I just followed the agreement process from gcc -v
, after I agreed it works fine for me.
With either string concatenation or string interpolation (via template literals).
Here with JavaScript template literal:
function geoPreview() {
var lat = document.getElementById("lat").value;
var long = document.getElementById("long").value;
window.location.href = `http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=${lat}&lon=${long}&setLatLon=Set`;
}
Both parameters are unused and can be removed.
Join strings with the +
operator:
window.location.href = "http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=" + elemA + "&lon=" + elemB + "&setLatLon=Set";
For more concise code, use JavaScript template literals to replace expressions with their string representations.
Template literals are enclosed by ``
and placeholders surrounded with ${}
:
window.location.href = `http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=${elemA}&lon=${elemB}&setLatLon=Set`;
Template literals are available since ECMAScript 2015 (ES6).
import re
sentence = ' hello apple'
re.sub(' ','',sentence) #helloworld (remove all spaces)
re.sub(' ',' ',sentence) #hello world (remove double spaces)
It has to be a constant - the value has to be computable at the time that the procedure is created, and that one computation has to provide the value that will always be used.
Look at the definition of sys.all_parameters
:
default_value
sql_variant
Ifhas_default_value
is 1, the value of this column is the value of the default for the parameter; otherwise,NULL
.
That is, whatever the default for a parameter is, it has to fit in that column.
As Alex K pointed out in the comments, you can just do:
CREATE PROCEDURE [dbo].[problemParam]
@StartDate INT = NULL,
@EndDate INT = NULL
AS
BEGIN
SET @StartDate = COALESCE(@StartDate,CONVERT(INT,(CONVERT(CHAR(8),GETDATE()-130,112))))
provided that NULL
isn't intended to be a valid value for @StartDate
.
As to the blog post you linked to in the comments - that's talking about a very specific context - that, the result of evaluating GETDATE()
within the context of a single query is often considered to be constant. I don't know of many people (unlike the blog author) who would consider a separate expression inside a UDF to be part of the same query as the query that calls the UDF.
Can be done using numpy where() function:
import pandas as pd
import numpy as np
In [716]: df = pd.DataFrame({"gene_name": ['SLC45A1', 'NECAP2', 'CLIC4', 'ADC', 'AGBL4'] , "BoolCol": [False, True, False, True, True] },
index=list("abcde"))
In [717]: df
Out[717]:
BoolCol gene_name
a False SLC45A1
b True NECAP2
c False CLIC4
d True ADC
e True AGBL4
In [718]: np.where(df["BoolCol"] == True)
Out[718]: (array([1, 3, 4]),)
In [719]: select_indices = list(np.where(df["BoolCol"] == True)[0])
In [720]: df.iloc[select_indices]
Out[720]:
BoolCol gene_name
b True NECAP2
d True ADC
e True AGBL4
Though you don't always need index for a match, but incase if you need:
In [796]: df.iloc[select_indices].index
Out[796]: Index([u'b', u'd', u'e'], dtype='object')
In [797]: df.iloc[select_indices].index.tolist()
Out[797]: ['b', 'd', 'e']

JAD is an excellent option if you want readable Java code as a result. If you really want to dig into the internals of the .class
file format though, you're going to want javap
. It's bundled with the JDK and allows you to "decompile" the hexadecimal bytecode into readable ASCII. The language it produces is still bytecode (not anything like Java), but it's fairly readable and extremely instructive.
Also, if you really want to, you can open up any .class
file in a hex editor and read the bytecode directly. The result is identical to using javap
.
My answer is little late but simple; but may help someone in future; I did experiment with angular versions such as 4.4.3, 5.1+, 6.x, 7.x, 8.x, 9.x and 10.x using $event (latest at the moment)
Template:
<select (change)="onChange($event)">
<option *ngFor="let v of values" [value]="v.id">{{v.name}}</option>
</select>
TS
export class MyComponent {
public onChange(event): void { // event will give you full breif of action
const newVal = event.target.value;
console.log(newVal);
}
}
This is a complete working Console solution based on the example provided in here:
class Program
{
static string[] words1 = new string[] { "brown", "jumped", "the", "fox", "quick" };
static void Main()
{
var result = Shuffle(words1);
foreach (var i in result)
{
Console.Write(i + " ");
}
Console.ReadKey();
}
static string[] Shuffle(string[] wordArray) {
Random random = new Random();
for (int i = wordArray.Length - 1; i > 0; i--)
{
int swapIndex = random.Next(i + 1);
string temp = wordArray[i];
wordArray[i] = wordArray[swapIndex];
wordArray[swapIndex] = temp;
}
return wordArray;
}
}
Ok, since we're weighing in with opinion:
I believe that table names should be plural. Tables are a collection (a table) of entities. Each row represents a single entity, and the table represents the collection. So I would call a table of Person entities People (or Persons, whatever takes your fancy).
For those who like to see singular "entity names" in queries, that's what I would use table aliases for:
SELECT person.Name
FROM People person
A bit like LINQ's "from person in people select person.Name".
As for 2, 3 and 4, I agree with @Lars.
Open the registry and search for key LoginMode

Update the LoginMode value as 2.
Your ProcExit label is your place where you release all the resources whether an error happened or not. For instance:
Public Sub SubA()
On Error Goto ProcError
Connection.Open
Open File for Writing
SomePreciousResource.GrabIt
ProcExit:
Connection.Close
Connection = Nothing
Close File
SomePreciousResource.Release
Exit Sub
ProcError:
MsgBox Err.Description
Resume ProcExit
End Sub
But svn log is still in reverse order, i.e. most recent entries are output first, scrolling off the top of my terminal and gone. I really want to see the last entries, i.e. the sorting order must be chronological. The only command that does this seems to be svn log -r 1:HEAD
but that takes much too long on a repository with some 10000 entries. I've come up this this:
Display the last 10 subversion entries in chronological order:
svn log -r $(svn log -l 10 | grep '^r[0-9]* ' | tail -1 | cut -f1 -d" "):HEAD
In your script, this part:
document.getElementById('Noite')
must be returning null
and you are also attempting to set the display
property to an invalid value. There are a couple of possible reasons for this first part to be null
.
You are running the script too early before the document has been loaded and thus the Noite
item can't be found.
There is no Noite
item in your HTML.
I should point out that your use of document.write()
in this case code probably signifies a problem. If the document has already loaded, then a new document.write()
will clear the old content and start a new fresh document so no Noite
item would be found.
If your document has not yet been loaded and thus you're doing document.write()
inline to add HTML inline to the current document, then your document has not yet been fully loaded so that's probably why it can't find the Noite
item.
The solution is probably to put this part of your script at the very end of your document so everything before it has already been loaded. So move this to the end of your body:
document.getElementById('Noite').style.display='block';
And, make sure that there are no document.write()
statements in javascript after the document has been loaded (because they will clear the previous document and start a new one).
In addition, setting the display
property to "display"
doesn't make sense to me. The valid options for that are "block"
, "inline"
, "none"
, "table"
, etc... I'm not aware of any option named "display"
for that style property. See here for valid options for teh display
property.
You can see the fixed code work here in this demo: http://jsfiddle.net/jfriend00/yVJY4/. That jsFiddle is configured to have the javascript placed at the end of the document body so it runs after the document has been loaded.
P.S. I should point out that your lack of braces for your if
statements and your inclusion of multiple statements on the same line makes your code very misleading and unclear.
I'm having a really hard time figuring out what you're asking, but here's a cleaned up version of your code that works which you can also see working here: http://jsfiddle.net/jfriend00/QCxwr/. Here's a list of the changes I made:
var
declarations to your variables (a good habit to always use).if
statement was changed into an if/else which is a lot more efficient and more self-documenting as to what you're doing.if
statement so it absolutely clear which statements are part of the if/else
and which are not.</dd>
tag you were inserting.style.display = '';
to style.display = 'block';

You can use System.currentTimeMillis()
.
At least in OpenJDK, Date
uses this under the covers.
The call in System
is to a native JVM method, so we can't say for sure there's no allocation happening under the covers, though it seems unlikely here.
The %pdb
magic command is good to use as well. Just say %pdb on
and subsequently the pdb
debugger will run on all exceptions, no matter how deep in the call stack. Very handy.
If you have a particular line that you want to debug, just raise an exception there (often you already are!) or use the %debug
magic command that other folks have been suggesting.
Another way to change data type using migration
step1: You need to remove the faulted data type field name using migration
ex:
rails g migration RemoveFieldNameFromTableName field_name:data_type
Here don't forget to specify data type for your field
Step 2: Now you can add field with correct data type
ex:
rails g migration AddFieldNameToTableName field_name:data_type
That's it, now your table will added with correct data type field, Happy ruby coding!!

Challenge: Can anyone do it with fewer defines and structs? ;-)
For those who need to build more than one jar from the project.
Create a function in gradle:
void jarFactory(Jar jarTask, jarName, mainClass) {
jarTask.doFirst {
println 'Build jar ' + jarTask.name + + ' started'
}
jarTask.manifest {
attributes(
'Main-Class': mainClass
)
}
jarTask.classifier = 'all'
jarTask.baseName = jarName
jarTask.from {
configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
}
{
exclude "META-INF/*.SF"
exclude "META-INF/*.DSA"
exclude "META-INF/*.RSA"
}
jarTask.with jar
jarTask.doFirst {
println 'Build jar ' + jarTask.name + ' ended'
}
}
then call:
task makeMyJar(type: Jar) {
jarFactory(it, 'MyJar', 'org.company.MainClass')
}
Works on gradle 5.
Jar will be placed at ./build/libs
.
Class Fraction:
public class Fraction {
private int num; // numerator
private int denom; // denominator
// default constructor
public Fraction() {}
// constructor
public Fraction( int a, int b ) {
num = a;
if ( b == 0 )
throw new ZeroDenomException();
else
denom = b;
}
// return string representation of ComplexNumber
@Override
public String toString() {
return "( " + num + " / " + denom + " )";
}
// the addition operation
public Fraction add(Fraction x){
return new Fraction(
x.num * denom + x.denom * num, x.denom * denom );
}
// the multiplication operation
public Fraction multiply(Fraction x) {
return new Fraction(x.num * num, x.denom * denom);
}
}
The main program:
static void main(String[] args){
Scanner input = new Scanner(System.in);
System.out.println("Enter numerator and denominator of first fraction");
int num1 =input.nextInt();
int denom1 =input.nextInt();
Fraction x = new Fraction(num1, denom1);
System.out.println("Enter numerator and denominator of second fraction");
int num2 =input.nextInt();
int denom2 =input.nextInt();
Fraction y = new Fraction(num2, denom2);
Fraction result = new Fraction();
System.out.println("Enter required operation: A (Add), M (Multiply)");
char op = input.next().charAt(0);
if(op == 'A') {
result = x.add(y);
System.out.println(x + " + " + y + " = " + result);
}
On newer distros (as of 2016), it seems that PIE is enabled by default so you will need to disable it explicitly when compiling.
Here's a little summary of commands which can be helpful when playing locally with buffer overflow exercises in general:
Disable canary:
gcc vuln.c -o vuln_disable_canary -fno-stack-protector
Disable DEP:
gcc vuln.c -o vuln_disable_dep -z execstack
Disable PIE:
gcc vuln.c -o vuln_disable_pie -no-pie
Disable all of protection mechanisms listed above (warning: for local testing only):
gcc vuln.c -o vuln_disable_all -fno-stack-protector -z execstack -no-pie
For 32-bit machines, you'll need to add the -m32
parameter as well.
Here is the extension method to load an image from URI:
public static BitmapImage GetBitmapImage(
this Uri imageAbsolutePath,
BitmapCacheOption bitmapCacheOption = BitmapCacheOption.Default)
{
BitmapImage image = new BitmapImage();
image.BeginInit();
image.CacheOption = bitmapCacheOption;
image.UriSource = imageAbsolutePath;
image.EndInit();
return image;
}
Sample of use:
Uri _imageUri = new Uri(imageAbsolutePath);
ImageXamlElement.Source = _imageUri.GetBitmapImage(BitmapCacheOption.OnLoad);
Simple as that!
In the earlier answers weight is passed to the constructor of a new SomeLayoutType.LayoutParams object. Still in many cases it's more convenient to use existing objects - it helps to avoid dealing with parameters we are not interested in.
An example:
// Get our View (TextView or anything) object:
View v = findViewById(R.id.our_view);
// Get params:
LinearLayout.LayoutParams loparams = (LinearLayout.LayoutParams) v.getLayoutParams();
// Set only target params:
loparams.height = 0;
loparams.weight = 1;
v.setLayoutParams(loparams);
import os
import glob
path = 'c:\\'
extension = 'csv'
os.chdir(path)
result = glob.glob('*.{}'.format(extension))
print(result)
I use the following command to load a project quickly (in linux)

I'm using virtualenvwrapper and don't want to modify $PATH, here's how:

You have to know the encoding of the string represented in bytes, but you can say System.Text.UTF8Encoding.GetString(bytes)
or System.Text.ASCIIEncoding.GetString(bytes)
. (I'm doing this from memory, so the API may not be exactly correct, but it's very close.)
For the answer to your second question, see this question.
Food for thought: what would a text-to-speech synthesizer do with <center>
?
You can use netstat this way for much faster results:
On Linux:
netstat -lnt | awk '$6 == "LISTEN" && $4 ~ /\.445$/'
On Mac:
netstat -anp tcp | awk '$6 == "LISTEN" && $4 ~ /\.445$/'
This will output a list of processes listening on the port (445 in this example) or it will output nothing if the port is free.
The ideal way to do it will be using "INSERT OVERWRITE DIRECTORY '/pathtofile' select * from temp where id > 100" instead of "hive -e 'select * from...' > /filepath.txt"
You can create a custom alertDialog and use a xml layout. in the layout, you can set the background color and textcolor.
Something like this:
Dialog dialog = new Dialog(this, android.R.style.Theme_Translucent_NoTitleBar);
LayoutInflater inflater = (LayoutInflater)ActivityName.this.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.custom_layout,(ViewGroup)findViewById(R.id.layout_root));
dialog.setContentView(view);
Just compare the year, month and day values.
Declare @DateToSearch DateTime
Set @DateToSearch = '14 AUG 2008'
SELECT *
FROM table1
WHERE Year(column_datetime) = Year(@DateToSearch)
AND Month(column_datetime) = Month(@DateToSearch)
AND Day(column_datetime) = Day(@DateToSearch)
You only need []
to instantiate an array - this is true regardless of its type. The fact that the array is of an array type is immaterial.
The same thing applies at the first level in your loop. It is merely an array and []
is a new empty array - job done.
As for the second level, if Thing
is a class then new Thing()
will be just fine. Otherwise, depending on the type, you may need a factory function or other expression to create one.
class Something {
private things: Thing[][];
constructor() {
this.things = [];
for(var i: number = 0; i < 10; i++) {
this.things[i] = [];
for(var j: number = 0; j< 10; j++) {
this.things[i][j] = new Thing();
}
}
}
}

You can use // instead of single /. That converts to int
directly.
Here you go:
data = []
table = soup.find('table', attrs={'class':'lineItemsTable'})
table_body = table.find('tbody')
rows = table_body.find_all('tr')
for row in rows:
cols = row.find_all('td')
cols = [ele.text.strip() for ele in cols]
data.append([ele for ele in cols if ele]) # Get rid of empty values
This gives you:

Couple of things to note:
Strictly speaking, a unique nullable column (or set of columns) can be NULL (or a record of NULLs) only once, since having the same value (and this includes NULL) more than once obviously violates the unique constraint.
However, that doesn't mean the concept of "unique nullable columns" is valid; to actually implement it in any relational database we just have to bear in mind that this kind of databases are meant to be normalized to properly work, and normalization usually involves the addition of several (non-entity) extra tables to establish relationships between the entities.
Let's work a basic example considering only one "unique nullable column", it's easy to expand it to more such columns.
Suppose we the information represented by a table like this:
create table the_entity_incorrect
(
id integer,
uniqnull integer null, /* we want this to be "unique and nullable" */
primary key (id)
);
We can do it by putting uniqnull apart and adding a second table to establish a relationship between uniqnull values and the_entity (rather than having uniqnull "inside" the_entity):
create table the_entity
(
id integer,
primary key(id)
);
create table the_relation
(
the_entity_id integer not null,
uniqnull integer not null,
unique(the_entity_id),
unique(uniqnull),
/* primary key can be both or either of the_entity_id or uniqnull */
primary key (the_entity_id, uniqnull),
foreign key (the_entity_id) references the_entity(id)
);
To associate a value of uniqnull to a row in the_entity we need to also add a row in the_relation.
For rows in the_entity were no uniqnull values are associated (i.e. for the ones we would put NULL in the_entity_incorrect) we simply do not add a row in the_relation.
Note that values for uniqnull will be unique for all the_relation, and also notice that for each value in the_entity there can be at most one value in the_relation, since the primary and foreign keys on it enforce this.
Then, if a value of 5 for uniqnull is to be associated with an the_entity id of 3, we need to:
start transaction;
insert into the_entity (id) values (3);
insert into the_relation (the_entity_id, uniqnull) values (3, 5);
commit;
And, if an id value of 10 for the_entity has no uniqnull counterpart, we only do:
start transaction;
insert into the_entity (id) values (10);
commit;
To denormalize this information and obtain the data a table like the_entity_incorrect would hold, we need to:
select
id, uniqnull
from
the_entity left outer join the_relation
on
the_entity.id = the_relation.the_entity_id
;
The "left outer join" operator ensures all rows from the_entity will appear in the result, putting NULL in the uniqnull column when no matching columns are present in the_relation.
Remember, any effort spent for some days (or weeks or months) in designing a well normalized database (and the corresponding denormalizing views and procedures) will save you years (or decades) of pain and wasted resources.
List constructor accepts any data structure that implements Collection interface to be used to build a list.
To get all the keys from a hash map to a list:
Map<String, Integer> map = new HashMap<String, Integer>();
List<String> keys = new ArrayList<>(map.keySet());
To get all the values from a hash map to a list:
Map<String, Integer> map = new HashMap<String, Integer>();
List<Integer> values = new ArrayList<>(map.values());
The copy/paste answer is git rm --cached -r .; git add .; git status
This command will ignore the files that have already been committed to a Git repository but now we have added them to .gitignore

Yes , i had to change the port :80 to :90 as port :80 was busy by some other system resource.

Thanks,
what about this:
# get difference between dates `"01.12.2013"` and `"31.12.2013"`
# weeks
difftime(strptime("26.03.2014", format = "%d.%m.%Y"),
strptime("14.01.2013", format = "%d.%m.%Y"),units="weeks")
Time difference of 62.28571 weeks
# months
(as.yearmon(strptime("26.03.2014", format = "%d.%m.%Y"))-
as.yearmon(strptime("14.01.2013", format = "%d.%m.%Y")))*12
[1] 14
# quarters
(as.yearqtr(strptime("26.03.2014", format = "%d.%m.%Y"))-
as.yearqtr(strptime("14.01.2013", format = "%d.%m.%Y")))*4
[1] 4
# years
year(strptime("26.03.2014", format = "%d.%m.%Y"))-
year(strptime("14.01.2013", format = "%d.%m.%Y"))
[1] 1
as.yearmon()
and as.yearqtr()
are in package zoo
. year()
is in package lubridate
.
What do you think?
