response = requests.post(url, data=data)
Depending on what kind of response your API returns, you will then probably want to look at response.text

(or possibly inspect response.status_code
first). See the quickstart docs here, especially this section.
From man 1 pkill
-f The pattern is normally only matched against the process name.
When -f is set, the full command line is used.
Which means, for example, if we see these lines in ps aux
:
apache 24268 0.0 2.6 388152 27116 ? S Jun13 0:10 /usr/sbin/httpd
apache 24272 0.0 2.6 387944 27104 ? S Jun13 0:09 /usr/sbin/httpd
apache 24319 0.0 2.6 387884 27316 ? S Jun15 0:04 /usr/sbin/httpd
We can kill them all using the pkill -f
option:
pkill -f httpd
If you want to know the number of visitors (as is titled in the question) and not the number of pageviews, then you'll need to create a custom report.
Google Analytics has changed the terminology they use within the reports. Now, visits is named "sessions" and unique visitors is named "users."
User - A unique person who has visited your website. Users may visit your website multiple times, and they will only be counted once.
Session - The number of different times that a visitor came to your site.
Pageviews - The total number of pages that a user has accessed.

Basically your code is okay, thats the right way to do this. Anyhow, there are some misunderstandings:
fetchUserData.cfm does not contain key/value pairs. So it doesn't make sense to address keys in mData. Just use mData[index]
dataTables expects some more info from your serverside. At least you should tell datatables how many items in total are on your serverside and how many are filtered. I just hardcoded this info to your data. You should get the right values from counts in your server sided script.
{
"iTotalRecords":"6",
"iTotalDisplayRecords":"6",
"aaData": [
[
"1",
"sameek",
"sam",
"sam",
"[email protected]",
"1",
""
],...
If you have the column names already set in the html part, you don't need to add sTitle.
The mRender Function takes three parameters:
So your mRender function should look like this:
"mRender": function(data, type, full) {
return '<a class="btn btn-info btn-sm" href=#/' + full[0] + '>' + 'Edit' + '</a>';
}

You can set the ReadOnly property to true.
Quoth the link:
When this property is set to true, the contents of the control cannot be changed by the user at runtime. With this property set to true, you can still set the value of the Text property in code. You can use this feature instead of disabling the control with the Enabled property to allow the contents to be copied and ToolTips to be shown.

subList function is a trick, the returned object is still in the original list. so if you do any operation in subList, it will cause the concurrent exception in your code, no matter it is single thread or multi thread.
You concrete problem is caused because you're mixing discouraged and old school scriptlets <% %>
with its successor EL ${}
. They do not share the same variable scope. The allFestivals
is not available in scriptlet scope and the i
is not available in EL scope.
You should install JSTL (<-- click the link for instructions) and declare it in top of JSP as follows:
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
and then iterate over the list as follows:
<c:forEach items="${allFestivals}" var="festival">
<tr>
<td>${festival.festivalName}</td>
<td>${festival.location}</td>
<td>${festival.startDate}</td>
<td>${festival.endDate}</td>
<td>${festival.URL}</td>
</tr>
</c:forEach>
(beware of possible XSS attack holes, use <c:out>
accordingly)
Don't forget to remove the <jsp:useBean>
as it has no utter value here when you're using a servlet as model-and-view controller. It would only lead to confusion. See also our servlets wiki page. Further you would do yourself a favour to disable scriptlets by the following entry in web.xml
so that you won't accidently use them:
<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<scripting-invalid>true</scripting-invalid>
</jsp-property-group>

i made a jsfiddle to do it in here:
function polarToCartesian(centerX, centerY, radius, angleInDegrees) {
var angleInRadians = (angleInDegrees-90) * Math.PI / 180.0;
return {
x: centerX + (radius * Math.cos(angleInRadians)),
y: centerY + (radius * Math.sin(angleInRadians))
};
}
function describeArc(x, y, radius, startAngle, endAngle){
var start = polarToCartesian(x, y, radius, endAngle);
var end = polarToCartesian(x, y, radius, startAngle);
var largeArcFlag = endAngle - startAngle <= 180 ? "0" : "1";
var d = [
"M", start.x, start.y,
"A", radius, radius, 0, largeArcFlag, 0, end.x, end.y
].join(" ");
return d;
}
console.log(describeArc(255,255,220,134,136))
all you need to do is to change the input of console.log and get the result in console
I was referencing a mapped drive and I found that the mapped drives are not always available to the user account that is running the scheduled task so I used \\IPADDRESS
instead of MAPDRIVELETTER:
and I am up and running.
I also had this problem with another style of implementation but I forgot where I got it since it was 2 years ago.
static string sha256(string randomString)
{
var crypt = new SHA256Managed();
string hash = String.Empty;
byte[] crypto = crypt.ComputeHash(Encoding.ASCII.GetBytes(randomString));
foreach (byte theByte in crypto)
{
hash += theByte.ToString("x2");
}
return hash;
}
When I input something like abcdefghi2013
for some reason it gives different results and results in errors in my login module.
Then I tried modifying the code the same way as suggested by Quuxplusone and changed the encoding from ASCII
to UTF8
then it finally worked!
static string sha256(string randomString)
{
var crypt = new System.Security.Cryptography.SHA256Managed();
var hash = new System.Text.StringBuilder();
byte[] crypto = crypt.ComputeHash(Encoding.UTF8.GetBytes(randomString));
foreach (byte theByte in crypto)
{
hash.Append(theByte.ToString("x2"));
}
return hash.ToString();
}
Thanks again Quuxplusone for the wonderful and detailed answer! :)
The accepted answer has it spot on, but if you might want to specify which class label should be assigned to a specific color or label you could do the following. I did a little label gymnastics with the colorbar, but making the plot itself reduces to a nice one-liner. This works great for plotting the results from classifications done with sklearn. Each label matches a (x,y) coordinate.
import matplotlib
import matplotlib.pyplot as plt
import numpy as np
x = [4,8,12,16,1,4,9,16]
y = [1,4,9,16,4,8,12,3]
label = [0,1,2,3,0,1,2,3]
colors = ['red','green','blue','purple']
fig = plt.figure(figsize=(8,8))
plt.scatter(x, y, c=label, cmap=matplotlib.colors.ListedColormap(colors))
cb = plt.colorbar()
loc = np.arange(0,max(label),max(label)/float(len(colors)))
cb.set_ticks(loc)
cb.set_ticklabels(colors)
Using a slightly modified version of this answer, one can generalise the above for N colors as follows:
import numpy as np
import matplotlib as mpl
import matplotlib.pyplot as plt
N = 23 # Number of labels
# setup the plot
fig, ax = plt.subplots(1,1, figsize=(6,6))
# define the data
x = np.random.rand(1000)
y = np.random.rand(1000)
tag = np.random.randint(0,N,1000) # Tag each point with a corresponding label
# define the colormap
cmap = plt.cm.jet
# extract all colors from the .jet map
cmaplist = [cmap(i) for i in range(cmap.N)]
# create the new map
cmap = cmap.from_list('Custom cmap', cmaplist, cmap.N)
# define the bins and normalize
bounds = np.linspace(0,N,N+1)
norm = mpl.colors.BoundaryNorm(bounds, cmap.N)
# make the scatter
scat = ax.scatter(x,y,c=tag,s=np.random.randint(100,500,N),cmap=cmap, norm=norm)
# create the colorbar
cb = plt.colorbar(scat, spacing='proportional',ticks=bounds)
cb.set_label('Custom cbar')
ax.set_title('Discrete color mappings')
plt.show()
Which gives:
In the custom validation method use:
errors.add(:base, "Custom error message")
as add_to_base has been deprecated.
errors.add_to_base("Custom error message")
For those using Swift 3, the equivalent method for the accepted answer is:
movieArr.sorted { $0.Name < $1.Name }
The last example get errors under 10.6.8 (Build 10K549) caused by the keyword "pause".
Replacing it by the word "wait" makes it work:
tell application "Terminal"
activate
my execCmd("ssh me@localhost", 1)
my execCmd("myPassw0rd", 0)
my execCmd("ls", 2)
my execCmd("exit", 0)
end tell
on execCmd(cmd, wait)
tell application "System Events"
tell application process "Terminal"
set frontmost to true
keystroke cmd
keystroke return
end tell
end tell
delay wait
end execCmd

Most of the methods described above did not work for me, maybe they are deprecated in the newer versions. The up-to-date guide can be found here: http://guides.rubyonrails.org/command_line.html#custom-rake-tasks

# You can use args from here
end
Invoke it like this

For example, lets say we want to display only the first 10 items of an array, we could do this using the SlicePipe like so:
<ul>
<li *ngFor="let item of items | slice:0:10">
{{ item }}
</li>
</ul>
In general, when you get an error like this, just do
yum provides ld-linux.so.2
then you'll see something like:
glibc-2.20-5.fc21.i686 : The GNU libc libraries
Repo : fedora
Matched from:
Provides : ld-linux.so.2
and then you just run the following like BRPocock wrote (in case you were wondering what the logic was...):
yum install glibc.i686
The only way I succeed to not having an error because of NULL, or special characters or empty string is by doing this:
SELECT REGEXP_REPLACE(COALESCE(<column>::character varying, '0'), '[^0-9]*' ,'0')::integer FROM table
ZIP Code is a highly localised field, and many countries have characters in their postcodes, e.g., UK, Canada. Therefore, in this example, you should use a string / varchar field to store it if at any point you would be shipping or getting users, customers, clients, etc. from other countries.
However, in the general case, you should use the recommended answer (printf("%05d", number);
).
You might need to register this DLL using the 32 bit version of regsvr32.exe

If you have a flash FLA file that shows the FLV movie you can add a button inside the FLA file. This button can be given an action to load the URL.

The answer that has 50 votes doesn't check for date in only checks for months. That answer is not correct. The code below works.
var dateFrom = "01/08/2017";
var dateTo = "01/10/2017";
var dateCheck = "05/09/2017";
var d1 = dateFrom.split("/");
var d2 = dateTo.split("/");
var c = dateCheck.split("/");
var from = new Date(d1); // -1 because months are from 0 to 11
var to = new Date(d2);
var check = new Date(c);
alert(check > from && check < to);
This is the code posted in another answer and I have changed the dates and that's how I noticed it doesn't work
var dateFrom = "02/05/2013";
var dateTo = "02/09/2013";
var dateCheck = "07/07/2013";
var d1 = dateFrom.split("/");
var d2 = dateTo.split("/");
var c = dateCheck.split("/");
var from = new Date(d1[2], parseInt(d1[1])-1, d1[0]); // -1 because months are from 0 to 11
var to = new Date(d2[2], parseInt(d2[1])-1, d2[0]);
var check = new Date(c[2], parseInt(c[1])-1, c[0]);
alert(check > from && check < to);

var resizeText = function(){
do {
// set new font size and determine resulting dimensions
textContainer.style.fontSize = fontSize + 'px';
textContainerHeight = textContainer.offsetHeight;
textContainerWidth = textContainer.offsetWidth;

var ratioHeight = Math.floor(textContainerHeight / maxHeight);
var ratioWidth = Math.floor(textContainerWidth / maxWidth);
var shrinkFactor = ratioHeight > ratioWidth ? ratioHeight : ratioWidth;
fontSize -= shrinkFactor;
} while ((textContainerHeight > maxHeight || textContainerWidth > maxWidth) && fontSize > minFontSize);
};
// watch for changes to text
$scope.$watch('text', function(newText, oldText){
if(newText === undefined) return;
// text was deleted
if(oldText !== undefined && newText.length < oldText.length){

None of those worked for me. I was trying to clone a directory from a private git server and entered my credentials false and then it wouldn't let me try different credentials on subsequent tries, it just errored out immediately with an authentication error.

This is way too vague to give you an answer relevant to your specific case. It depends on a lot of things. Jeff Atwood (founder of this site) actually wrote about this. For the most part, though, if you have the right indexes and you properly do your JOINs it is usually going to be faster to do 1 trip than several.
You could try the following code. I can't vouch for browser compatibility though, so you'll have to test that.
function testImage(URL) {
var tester=new Image();
tester.onload=imageFound;
tester.onerror=imageNotFound;
tester.src=URL;
}
function imageFound() {
alert('That image is found and loaded');
}
function imageNotFound() {
alert('That image was not found.');
}
testImage("http://foo.com/bar.jpg");

Brief Solution:
The better approach is to replace all compile
dependencies with implementation
dependencies. And only where you leak a module’s interface, you should use api
. That should cause a lot less recompilation.
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:25.4.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
// …
testImplementation 'junit:junit:4.12'
androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
}
Explain More:
Before Android Gradle plugin 3.0: we had a big problem which is one code change causes all modules to be recompiled. The root cause for this is that Gradle doesn’t know if you leak the interface of a module through another one or not.
After Android Gradle plugin 3.0: the latest Android Gradle plugin now requires you to explicitly define if you leak a module’s interface. Based on that it can make the right choice on what it should recompile.
As such the compile
dependency has been deprecated and replaced by two new ones:
api
: you leak the interface of this module through your own interface, meaning exactly the same as the old compile
dependency
implementation
: you only use this module internally and does not leak it through your interface
So now you can explicitly tell Gradle to recompile a module if the interface of a used module changes or not.

The Wikipedia newline article might help you out. Here is an excerpt:
The different newline conventions often cause text files that have been transferred between systems of different types to be displayed incorrectly. For example, files originating on Unix or Apple Macintosh systems may appear as a single long line on some programs running on Microsoft Windows. Conversely, when viewing a file originating from a Windows computer on a Unix system, the extra CR may be displayed as ^M or at the end of each line or as a second line break.
Morgan :- Morgan is a middleware which will help us to identify the clients who are accessing our application. Basically a logger.
To Use Morgan, We need to follow below steps :-
npm install --save morgan
This will add morgan to json.package file
var morgan = require('morgan');
3> // create a write stream (in append mode)
var accessLogStream = fs.createWriteStream(
path.join(__dirname, 'access.log'), {flags: 'a'}
);
// setup the logger
app.use(morgan('combined', {stream: accessLogStream}));
Note: Make sure you do not plumb above blindly make sure you have every conditions where you need .
Above will automatically create a access.log file to your root once user will access your app.
var strcmp = new Intl.Collator(undefined, {numeric:true, sensitivity:'base'}).compare;
Usage: strcmp(string1, string2)
Result: 1
means string1 is bigger, 0
means equal, -1
means string2 is bigger.
This has higher performance than String.prototype.localeCompare
Also, numeric:true
makes it do logical number comparison
You can also use list subsetting to select the element you want to convert. It would be useful if your list had more than 1 element.
as.numeric(a[[1]])
create table Customer(
CustId int primary key,
CustName varchar(20),
DOB date);
insert into Customer values(1,'kingle', TO_DATE('1994-12-16 12:00:00', 'yyyy-MM-dd hh:mi:ss'));

I was looking into this issue a bit for my own purposes; I had a slice of structs (including some pointers) and I wanted to make sure I got it right; ended up on this thread, and wanted to share my results.
To practice, I did a little go playground: https://play.golang.org/p/9i4gPx3lnY
which evals to this:
package main
import "fmt"
type Blah struct {
babyKitten int
kittenSays *string
}
func main() {
meow := "meow"
Blahs := []Blah{}
fmt.Printf("Blahs: %v\n", Blahs)
Blahs = append(Blahs, Blah{1, &meow})
fmt.Printf("Blahs: %v\n", Blahs)
Blahs = append(Blahs, Blah{2, &meow})
fmt.Printf("Blahs: %v\n", Blahs)
//fmt.Printf("kittenSays: %v\n", *Blahs[0].kittenSays)
Blahs = nil
meow2 := "nyan"
fmt.Printf("Blahs: %v\n", Blahs)
Blahs = append(Blahs, Blah{1, &meow2})
fmt.Printf("Blahs: %v\n", Blahs)
fmt.Printf("kittenSays: %v\n", *Blahs[0].kittenSays)
}
Running that code as-is will show the same memory address for both "meow" and "meow2" variables as being the same:
Blahs: []
Blahs: [{1 0x1030e0c0}]
Blahs: [{1 0x1030e0c0} {2 0x1030e0c0}]
Blahs: []
Blahs: [{1 0x1030e0f0}]
kittenSays: nyan
which I think confirms that the struct is garbage collected. Oddly enough, uncommenting the commented print line, will yield different memory addresses for the meows:
Blahs: []
Blahs: [{1 0x1030e0c0}]
Blahs: [{1 0x1030e0c0} {2 0x1030e0c0}]
kittenSays: meow
Blahs: []
Blahs: [{1 0x1030e0f8}]
kittenSays: nyan
I think this may be due to the print being deferred in some way (?), but interesting illustration of some memory mgmt behavior, and one more vote for:
[]MyStruct = nil
Also if you want to do something like ClassB.Run("thing");
, make sure the Method Run();
is static
or you could call it like this: thing.Run("thing");
.
Set box-sizing
property to border-box
:
div {_x000D_
box-sizing: border-box;_x000D_
-moz-box-sizing: border-box;_x000D_
-webkit-box-sizing: border-box;_x000D_
width: 100px;_x000D_
height: 100px;_x000D_
border: 20px solid #f00;_x000D_
background: #00f;_x000D_
margin: 10px;_x000D_
}_x000D_
_x000D_
div + div {_x000D_
border: 10px solid red;_x000D_
}
_x000D_
<div>Hello!</div>_x000D_
<div>Hello!</div>
_x000D_
It works on IE8 & above.
So first of all, pandas updates using the index. When an update command does not update anything, check both left-hand side and right-hand side. If you don't update the indices to follow your identification logic, you can do something along the lines of
>>> df.loc[df.filename == 'test2.dat', 'n'] = df2[df2.filename == 'test2.dat'].loc[0]['n']
>>> df
Out[331]:
filename m n
0 test0.dat 12 None
1 test2.dat 13 16
If you want to do this for the whole table, I suggest a method I believe is superior to the previously mentioned ones: since your identifier is filename
, set filename
as your index, and then use update()
as you wanted to. Both merge
and the apply()
approach contain unnecessary overhead:
>>> df.set_index('filename', inplace=True)
>>> df2.set_index('filename', inplace=True)
>>> df.update(df2)
>>> df
Out[292]:
m n
filename
test0.dat 12 None
test2.dat 13 16
You need to use a <br>
because your Content-Type
is text/html
.
It works without the Content-Type
header because then your e-mail will be interpreted as plain text. If you really want to use \n
you should use Content-Type: text/plain
but then you'll lose any markup.
Also check out similar question here.
If you need to use the latest versions of SciPy rather than the packaged version, without going through the hassle of building BLAS and LAPACK, you can follow the below procedure.
Install linear algebra libraries from repository (for Ubuntu),
sudo apt-get install gfortran libopenblas-dev liblapack-dev
Then install SciPy, (after downloading the SciPy source): python setup.py install
or
pip install scipy
As the case may be.
You have a problem with a png file maybe, look here :
1 more Caused by: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details at com.android.builder.png.AaptProcess$NotifierProcessOutput.handleOutput(AaptProcess.java:454)
It can be corrupted image or jpeg image with png extension
You can just specify the python version when running a program:
for python 2:
python filename.py
for python 3:
python3 filename.py
With JUnit5 and @DataJpaTest
test will look like (kotlin code):
@DataJpaTest
@ExtendWith(value = [SpringExtension::class])
class ActivityJpaTest {
@Autowired
lateinit var entityManager: TestEntityManager
@Autowired
lateinit var myEntityRepository: MyEntityRepository
@Test
fun shouldSaveEntity() {
// when
val savedEntity = myEntityRepository.save(MyEntity(1, "test")
// then
Assertions.assertNotNull(entityManager.find(MyEntity::class.java, savedEntity.id))
}
}
You could use TestEntityManager
from org.springframework.boot.test.autoconfigure.orm.jpa.TestEntityManager
package in order to validate entity state.
$IP_Array = (Get-Content test2.csv)[0].split(",")
foreach ( $IP in $IP_Array){
$IP
}
Get-content Filename returns an array of strings for each line.
On the first string only, I split it based on ",". Dumping it into $IP_Array.
$IP_Array = (Get-Content test2.csv)[0].split(",")
foreach ( $IP in $IP_Array){
if ($IP -eq "2.2.2.2") {
Write-Host "Found $IP"
}
}
Please refer to this for the example .The main point is to use the groupProperty()
, and the related aggregate functions provided by the Projections class.
For example :
SELECT column_name, max(column_name) , min (column_name) , count(column_name)
FROM table_name
WHERE column_name > xxxxx
GROUP BY column_name
Its equivalent criteria object is :
List result = session.createCriteria(SomeTable.class)
.add(Restrictions.ge("someColumn", xxxxx))
.setProjection(Projections.projectionList()
.add(Projections.groupProperty("someColumn"))
.add(Projections.max("someColumn"))
.add(Projections.min("someColumn"))
.add(Projections.count("someColumn"))
).list();
If your xml is written by java.lang.String
you can just using HttpClient
in this way
public void post() throws Exception{
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://www.baidu.com");
String xml = "<xml>xxxx</xml>";
HttpEntity entity = new ByteArrayEntity(xml.getBytes("UTF-8"));
post.setEntity(entity);
HttpResponse response = client.execute(post);
String result = EntityUtils.toString(response.getEntity());
}
pay attention to the Exceptions.
BTW, the example is written by the httpclient version 4.x
I went into wp-config/ and deleted the object-cache.php and advanced-cache.php and it worked fine for me.
After two dozens of comments to understand the situation, it was found that the libhdf5.so.7
was actually a symlink (with several levels of indirection) to a file that was not shared between the queued processes and the interactive processes. This means even though the symlink itself lies on a shared filesystem, the contents of the file do not and as a result the process was seeing different versions of the library.
For future reference: other than checking LD_LIBRARY_PATH
, it's always a good idea to check a library with nm -D
to see if the symbols actually exist. In this case it was found that they do exist in interactive mode but not when run in the queue. A quick md5sum
revealed that the files were actually different.
There are a few yet to be mentioned techniques available for you. Start with setting the contentType property in your ajax params.
Building on pradeek's example:
$('form').submit(function (e) {
var data;
data = new FormData();
data.append('file', $('#file')[0].files[0]);
$.ajax({
url: 'http://hacheck.tel.fer.hr/xml.pl',
data: data,
processData: false,
type: 'POST',
// This will override the content type header,
// regardless of whether content is actually sent.
// Defaults to 'application/x-www-form-urlencoded'
contentType: 'multipart/form-data',
//Before 1.5.1 you had to do this:
beforeSend: function (x) {
if (x && x.overrideMimeType) {
x.overrideMimeType("multipart/form-data");
}
},
// Now you should be able to do this:
mimeType: 'multipart/form-data', //Property added in 1.5.1
success: function (data) {
alert(data);
}
});
e.preventDefault();
});
In some cases when forcing jQuery ajax to do non-expected things, the beforeSend
event is a great place to do it. For a while people were using beforeSend
to override the mimeType before that was added into jQuery in 1.5.1. You should be able to modify just about anything on the jqXHR object in the before send event.
In my case, it was different! But I think sharing my experience might help someone!
In MAC, the 'keychain access' has saved my previous 'Github' password. I was trying with a new GitHub repository, and it never worked. When I removed the old GitHub password from 'keychain access' from my MAC machine it worked! I hope it helps someone.
It seems jQuery's :visible
selector does not work for some inline elements in Chrome. The solution is to add a display style, like "block"
or "inline-block"
to make it work.
Also note that jQuery has a somewhat different definition of what is visible than many developers:
Elements are considered visible if they consume space in the document.
Visible elements have a width or height that is greater than zero.
In other words, an element must have a non-zero width and height to consume space and be visible.
Elements with
visibility: hidden
oropacity: 0
are considered visible, since they still consume space in the layout.
On the other hand, even if its visibility
is set to hidden
or the opacity is zero, it's still :visible
to jQuery as it consumes space, which can be confusing when the CSS explicitly says its visibility is hidden.
Elements that are not in a document are considered hidden; jQuery does not have a way to know if they will be visible when appended to a document since it depends on the applicable styles.
All option elements are considered hidden, regardless of their selected state.
During animations that hide an element, the element is considered visible until the end of the animation. During animations to show an element, the element is considered visible at the start at the animation.
The easy way to look at it, is that if you can see the element on the screen, even if you can't see its content, it's transparent etc., it's visible, i.e. it takes up space.
I cleaned up your markup a little and added a display style (i.e. setting the elements display to "block" etc), and this works for me:
Official API reference for :visible
As of jQuery 3, the definition of :visible
has changed slightly
jQuery 3 slightly modifies the meaning of
:visible
(and therefore of:hidden
).
Starting with this version, elements will be considered:visible
if they have any layout boxes, including those of zero width and/or height. For example,br
elements and inline elements with no content will be selected by the:visible
selector.
The parser is having trouble concatenating your string. Try this:
write-host 'value is : '$i' '$($ds.Tables[1].Rows[$i][0])
Edit: Using double quotes might also be clearer since you can include the expressions within the quoted string:
write-host "value is : $i $($ds.Tables[1].Rows[$i][0])"
I have jus implement this library:https://github.com/jose78/go-collection. This is an example about how to use the Foreach loop:
package main
import (
"fmt"
col "github.com/jose78/go-collection/collections"
)
type user struct {
name string
age int
id int
}
func main() {
newList := col.ListType{user{"Alvaro", 6, 1}, user{"Sofia", 3, 2}}
newList = append(newList, user{"Mon", 0, 3})
newList.Foreach(simpleLoop)
if err := newList.Foreach(simpleLoopWithError); err != nil{
fmt.Printf("This error >>> %v <<< was produced", err )
}
}
var simpleLoop col.FnForeachList = func(mapper interface{}, index int) {
fmt.Printf("%d.- item:%v\n", index, mapper)
}
var simpleLoopWithError col.FnForeachList = func(mapper interface{}, index int) {
if index > 1{
panic(fmt.Sprintf("Error produced with index == %d\n", index))
}
fmt.Printf("%d.- item:%v\n", index, mapper)
}
The result of this execution should be:
0.- item:{Alvaro 6 1}
1.- item:{Sofia 3 2}
2.- item:{Mon 0 3}
0.- item:{Alvaro 6 1}
1.- item:{Sofia 3 2}
Recovered in f Error produced with index == 2
ERROR: Error produced with index == 2
This error >>> Error produced with index == 2
<<< was produced
user.no_of_logins += 1
session.commit()
Sometime it is fixed by the Padding .. if you can play with that, then, it should fix your problem
<style type=text/css>
YourbuttonByID {Padding: 20px 80px; "for example" padding-left:50px;
padding-right:30px "to fix the text in the middle
without interfering with the text itself"}
</style>
It worked for me
Note the ""
at the beginning and at the end!

NullPointerException with JSP can also happen if:
A getter returns a non-public inner class.
This code will fail if you remove Getters's access modifier or make it private or protected.

Using PowerShell
From Windows 8.1 and Windows Server 2012 R2 (Windows PowerShell 4.0) and upwards, you can create a self-signed certificate using the new New-SelfSignedCertificate
cmdlet:
Examples:
New-SelfSignedCertificate -DnsName www.mydomain.com -CertStoreLocation cert:\LocalMachine\My
New-SelfSignedCertificate -DnsName subdomain.mydomain.com -CertStoreLocation cert:\LocalMachine\My
New-SelfSignedCertificate -DnsName *.mydomain.com -CertStoreLocation cert:\LocalMachine\My
Using the IIS Manager
www.domain.com
or subdomain.domain.com
With the latest Firefox, I must use:
<script type="text/javascript">...</script>
Or else the script may not run properly.
One more idea for you. Create a rake task that calls rails server with the -p.
task "start" => :environment do
system 'rails server -p 3001'
end
then call rake start
instead of rails server
You can take the SelectedItem
and cast it back to your class
and access its properties
.
MessageBox.Show(((ComboboxItem)ComboBox_Countries_In_Silvers.SelectedItem).Value);
Edit You can try using DataTextField and DataValueField, I used it with DataSource.
ComboBox_Servers.DataTextField = "Text";
ComboBox_Servers.DataValueField = "Value";
Use includes javascript in-build function, but not work in Internet Explorer
var optval = [];
optval.push('A');
optval.push('B');
optval.push('C');
We can search string A in javascript array as:
optval.includes('A') // =====> return true
Check the pointer for NULL
and then using strlen
to see if it returns 0
.
NULL
check is important because passing NULL
pointer to strlen
invokes an Undefined Behavior.
This is a very common question seen on Stackoverflow.
The important part here is not the command displayed in the error, but what the actual error tells you instead.
a Quick breakdown on why this error is received.
cmd.exe
Being a terminal window relies on input and system Environment variables, in order to perform what you request it to do. it does NOT know the location of everything and it also does not know when to distinguish between commands or executable names which are separated by whitespace like space and tab or commands with whitespace as switch variables.
How do I fix this:
When Actual Command/executable fails
First we make sure, is the executable actually installed? If yes, continue with the rest, if not, install it first.
If you have any executable which you are attempting to run from cmd.exe
then you need to tell cmd.exe
where this file is located. There are 2 ways of doing this.
specify the full path to the file.
"C:\My_Files\mycommand.exe"
Add the location of the file to your environment Variables.
Goto:
------> Control Panel-> System-> Advanced System Settings->Environment Variables
In the System Variables
Window, locate path
and select edit
Now simply add your path to the end of the string, seperated by a semicolon ;
as:
;C:\My_Files\
Save the changes and exit. You need to make sure that ANY cmd.exe
windows you had open are then closed and re-opened to allow it to re-import the environment variables.
Now you should be able to run mycommand.exe from any path, within cmd.exe
as the environment is aware of the path to it.
When C:\Program
or Similar fails
This is a very simple error. Each string after a white space is seen as a different command in cmd.exe
terminal, you simply have to enclose the entire path in double quotes in order for cmd.exe
to see it as a single string, and not separate commands.
So to execute C:\Program Files\My-App\Mobile.exe
simply run as:
"C:\Program Files\My-App\Mobile.exe"
If you don't have access to the v$ views (as suggested by Quassnoi) there are two alternatives
select utl_inaddr.get_host_name from dual
and
select sys_context('USERENV','SERVER_HOST') from dual
Personally I'd tend towards the last as it doesn't require any grants/privileges which makes it easier from stored procedures.
Ideally you shouldn't be splitting strings in T-SQL at all.
Barring that change, on older versions before SQL Server 2016, create a split function:
CREATE FUNCTION dbo.SplitStrings
(
@List nvarchar(max),
@Delimiter nvarchar(2)
)
RETURNS TABLE
WITH SCHEMABINDING
AS
RETURN ( WITH x(x) AS
(
SELECT CONVERT(xml, N'<root><i>'
+ REPLACE(@List, @Delimiter, N'</i><i>')
+ N'</i></root>')
)
SELECT Item = LTRIM(RTRIM(i.i.value(N'.',N'nvarchar(max)')))
FROM x CROSS APPLY x.nodes(N'//root/i') AS i(i)
);
GO
Now you can say:
DECLARE @Values varchar(1000);
SET @Values = 'A, B, C';
SELECT blah
FROM dbo.foo
INNER JOIN dbo.SplitStrings(@Values, ',') AS s
ON s.Item = foo.myField;
On SQL Server 2016 or above (or Azure SQL Database), it is much simpler and more efficient, however you do have to manually apply LTRIM()
to take away any leading spaces:
DECLARE @Values varchar(1000) = 'A, B, C';
SELECT blah
FROM dbo.foo
INNER JOIN STRING_SPLIT(@Values, ',') AS s
ON LTRIM(s.value) = foo.myField;
From the Java documentation (not the javadoc API):
http://download.oracle.com/javase/6/docs/technotes/guides/net/proxies.html
Set the JVM flags http.proxyHost
and http.proxyPort
when starting your JVM on the command line.
This is usually done in a shell script (in Unix) or bat file (in Windows). Here's the example with the Unix shell script:
JAVA_FLAGS=-Dhttp.proxyHost=10.0.0.100 -Dhttp.proxyPort=8800
java ${JAVA_FLAGS} ...
When using containers such as JBoss or WebLogic, my solution is to edit the start-up scripts supplied by the vendor.
Many developers are familiar with the Java API (javadocs), but many times the rest of the documentation is overlooked. It contains a lot of interesting information: http://download.oracle.com/javase/6/docs/technotes/guides/
Update : If you do not want to use proxy to resolve some local/intranet hosts, check out the comment from @Tomalak:
Also don't forget the http.nonProxyHosts property!
-Dhttp.nonProxyHosts="localhost|127.0.0.1|10.*.*.*|*.foo.com??|etc"
Most probably you won't be able to read Word documents without COM.
Writing was covered in this topic
To answer the question asked, here is the most accurate SQL to accomplish the job, you can combine it with PL/SQL loop to actually run kill statements:
select ses.USERNAME,
substr(MACHINE,1,10) as MACHINE,
substr(module,1,25) as module,
status,
'alter system kill session '''||SID||','||ses.SERIAL#||''';' as kill
from v$session ses LEFT OUTER JOIN v$process p ON (ses.paddr=p.addr)
where schemaname <> 'SYS'
and not exists
(select 1
from DBA_ROLE_PRIVS
where GRANTED_ROLE='DBA'
and schemaname=grantee)
and machine!='yourlocalhostname'
order by LAST_CALL_ET desc;
The solution for me (openSUSE Leap 42.3, KDE) was to rename the folder ~/.gnupg
which apparently contained the cached keys and profiles.
After KDE logout/logon the ssh-add/agent is running again and the folder is created from scratch, but the old keys are all gone.
I didn't have success with the other approaches.
In Java a reference type assigned null
has no value at all. A string assigned ""
has a value: an empty string, which is to say a string with no characters in it. When a variable is assigned null
it means there is no underlying object of any kind, string or otherwise.
In my case, it was due to an IP address that Apache is listening to. Previously I have set it to 192.168.10.6 and recently Apache service is not running. I noticed that due to My laptop wifi changed recently and new IP is different. After fixing the wifi IP to laptop previous IP, Apache service is running again without any error.
Also if you don't want to change wifi IP then remove/comment that hardcode IP in httpd.conf file to resolve conflict.
According to 'Getting Started With LLVM Core Libraries' book (c):
In fact, the name LLVM might refer to any of the following:
The LLVM project/infrastructure: This is an umbrella for several projects that, together, form a complete compiler: frontends, backends, optimizers, assemblers, linkers, libc++, compiler-rt, and a JIT engine. The word "LLVM" has this meaning, for example, in the following sentence: "LLVM is comprised of several projects".
An LLVM-based compiler: This is a compiler built partially or completely with the LLVM infrastructure. For example, a compiler might use LLVM for the frontend and backend but use GCC and GNU system libraries to perform the final link. LLVM has this meaning in the following sentence, for example: "I used LLVM to compile C programs to a MIPS platform".
LLVM libraries: This is the reusable code portion of the LLVM infrastructure. For example, LLVM has this meaning in the sentence: "My project uses LLVM to generate code through its Just-in-Time compilation framework".
LLVM core: The optimizations that happen at the intermediate language level and the backend algorithms form the LLVM core where the project started. LLVM has this meaning in the following sentence: "LLVM and Clang are two different projects".
The LLVM IR: This is the LLVM compiler intermediate representation. LLVM has this meaning when used in sentences such as "I built a frontend that translates my own language to LLVM".

Will execute after the page along with all its contents are done loading. This means that all images, CSS (and content defined by CSS like custom fonts and images), scripts, etc. are all loaded. This happens event fires when your browser's "Stop" -icon becomes gray, so to speak. This is very useful to detect when the document along with all its contents are loaded.
$(document).ready();
This on the other hand will fire as soon as the web browser is capable of running your JavaScript, which happens after the parser is done with the DOM. This is useful if you want to execute JavaScript as soon as possible.
$(window).unload();
This event will be fired when you are navigating off the page. That could be Refresh/F5, pressing the previous page button, navigating to another website or closing the entire tab/window.
To sum up, ready() will be fired before load(), and unload() will be the last to be fired.
In regards to this question, this can be easily achieved using a few lines of SASS;
HTML:
<a href="https://www.urbandictionary.com/define.php?term=techninja" data-tool-tip="What's a tech ninja?" target="_blank"><i class="fas fa-2x fa-user-ninja" id="tech--ninja"></i></a>
CSS output would be:
a[data-tool-tip]{
position: relative;
text-decoration: none;
color: rgba(255,255,255,0.75);
}
a[data-tool-tip]::after{
content: attr(data-tool-tip);
display: block;
position: absolute;
background-color: dimgrey;
padding: 1em 3em;
color: white;
border-radius: 5px;
font-size: .5em;
bottom: 0;
left: -180%;
white-space: nowrap;
transform: scale(0);
transition:
transform ease-out 150ms,
bottom ease-out 150ms;
}
a[data-tool-tip]:hover::after{
transform: scale(1);
bottom: 200%;
}
Basically the attribute selector [data-tool-tip] selects the content of whatever's inside and allows you to animate it however you want.
One-liner solution:
The following code uses object URLs, which is much more efficient than data URL for viewing large images (A data URL is a huge string containing all of the file data, whereas an object URL, is just a short string referencing the file data in-memory):
<img id="blah" alt="your image" width="100" height="100" />_x000D_
_x000D_
<input type="file" _x000D_
onchange="document.getElementById('blah').src = window.URL.createObjectURL(this.files[0])">
_x000D_
Generated URL will be like:
blob:http%3A//localhost/7514bc74-65d4-4cf0-a0df-3de016824345

Beautiful Soup handles entity conversion. In Beautiful Soup 3, you'll need to specify the convertEntities
argument to the BeautifulSoup
constructor (see the 'Entity Conversion' section of the archived docs). In Beautiful Soup 4, entities get decoded automatically.

>>> BeautifulSoup("<p>£682m</p>",
... convertEntities=BeautifulSoup.HTML_ENTITIES)

With modern Python Exceptions, you don't need to abuse .message
, or override .__str__()
or .__repr__()
or any of it. If all you want is an informative message when your exception is raised, do this:
class MyException(Exception):
pass
raise MyException("My hovercraft is full of eels")
That will give a traceback ending with MyException: My hovercraft is full of eels
.
If you want more flexibility from the exception, you could pass a dictionary as the argument:
raise MyException({"message":"My hovercraft is full of animals", "animal":"eels"})
However, to get at those details in an except
block is a bit more complicated. The details are stored in the args
attribute, which is a list. You would need to do something like this:
try:
raise MyException({"message":"My hovercraft is full of animals", "animal":"eels"})
except MyException as e:
details = e.args[0]
print(details["animal"])
It is still possible to pass in multiple items to the exception and access them via tuple indexes, but this is highly discouraged (and was even intended for deprecation a while back). If you do need more than a single piece of information and the above method is not sufficient for you, then you should subclass Exception
as described in the tutorial.
class MyError(Exception):
def __init__(self, message, animal):
self.message = message
self.animal = animal
def __str__(self):
return self.message
I've had some luck with the Java Service Wrapper

The best way is to build your script in a way it cannot create any errors! When there is something that can create a Notice or an Error there is something wrong with your script and the checking of variables and environment!

Selecting a checkbox is similar to clicking a button.
driver.findElement(By.id("idOfTheElement")).click();
will do.
However, you can also see whether the checkbox is already checked. The following snippet checks whether the checkbox is selected or not. If it is not selected, then it selects.
if ( !driver.findElement(By.id("idOfTheElement")).isSelected() )
{
driver.findElement(By.id("idOfTheElement")).click();

I got this error when running a query without SSL.
Simply changing the URL scheme of my request from HTTP to HTTPS fixed it.
I got this problem in Visual Studio 2012 in a solution that had many projects. Rebuilding each project in the solution manually in the same order as the Project Build Order (right-click and rebuild in Solution Explorer) fixed it for me.
Eventually I got to one that gave me a compile error. I fixed the error, and the solution would build correctly after that.
@Dan,
Do I not need msdtc enabled for transactions to work?
Only distributed transactions - Those that involve more than a single connection. Make doubly sure you are only opening a single connection within the transaction and it won't escalate - Performance will be much better too.
.c_str()
returns a const char*
. If you need a mutable version, you will need to produce a copy yourself.
One options will be to show the selected option above (or below) the select list like following:
HTML
<div id="selText"><span> </span></div><br/>
<select size="4" id="mySelect" style="width:65px;color:#f98ad3;">
<option value="1" selected>option 1 The Long Option</option>
<option value="2">option 2</option>
<option value="3">option 3</option>
<option value="4">option 4</option>
<option value="5">option 5 Another Longer than the Long Option ;)</option>
<option value="6">option 6</option>
</select>

PS:- Set height of div#selText otherwise it will keep shifting select list downward.
To get the behavior you want you need to wait for the process to finish before you exit Main()
. To be able to tell when your process is done you need to return a Task
instead of a void
from your function, you should never return void
from a async
function unless you are working with events.
A re-written version of your program that works correctly would be
class Program { static void Main(string[] args) { Debug.WriteLine("Calling DoDownload"); var downloadTask = DoDownloadAsync(); Debug.WriteLine("DoDownload done"); downloadTask.Wait(); //Waits for the background task to complete before finishing. } private static async Task DoDownloadAsync() { WebClient w = new WebClient(); string txt = await w.DownloadStringTaskAsync("http://www.google.com/"); Debug.WriteLine(txt); } }
Because you can not await
in Main()
I had to do the Wait()
function instead. If this was a application that had a SynchronizationContext I would do await downloadTask;
instead and make the function this was being called from async
.
Not tested, but the closer you can get seems to be is with AutoCompleteTextView. You can write an adapter wich ignores the filter functions. Something like:
class UnconditionalArrayAdapter<T> extends ArrayAdapter<T> {
final List<T> items;
public UnconditionalArrayAdapter(Context context, int textViewResourceId, List<T> items) {
super(context, textViewResourceId, items);
this.items = items;
}
public Filter getFilter() {
return new NullFilter();
}
class NullFilter extends Filter {
protected Filter.FilterResults performFiltering(CharSequence constraint) {
final FilterResults results = new FilterResults();
results.values = items;
return results;
}
protected void publishResults(CharSequence constraint, Filter.FilterResults results) {
items.clear(); // `items` must be final, thus we need to copy the elements by hand.
for (Object item : (List) results.values) {
items.add((String) item);
}
if (results.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
}
}
}
... then in your onCreate:
String[] COUNTRIES = new String[] {"Belgium", "France", "Italy", "Germany"};
List<String> contriesList = Arrays.asList(COUNTRIES());
ArrayAdapter<String> adapter = new UnconditionalArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, contriesList);
AutoCompleteTextView textView = (AutoCompleteTextView)
findViewById(R.id.countries_list);
textView.setAdapter(adapter);
The code is not tested, there can be some features with the filtering method I did not consider, but there you have it, the basic principles to emulate a ComboBox with an AutoCompleteTextView.
Edit
Fixed NullFilter implementation.
We need access on the items, thus the constructor of the UnconditionalArrayAdapter
needs to take a reference to a List (kind of a buffer).
You can also use e.g. adapter = new UnconditionalArrayAdapter<String>(..., new ArrayList<String>);
and then use adapter.add("Luxemburg")
, so you don't need to manage the buffer list.
switch(i)
will throw a NullPointerException if i is null
, because it will try to unbox the Integer
into an int
. So case null
, which happens to be illegal, would never have been reached anyway.
You need to check that i is not null before the switch
statement.

And this line is how.
It is ignored.
It will fail to run, and should be changed to point to the proper location. Or env
should be used.
It will fail to run, and probably fail to run under a different version regardless.

Sometimes you want to have your GridView as simple as:
<asp:GridView ID="grid" runat="server" />
You don't want to specify any BoundField, you just want to bind your grid to DataReader. The following code helped me to format DateTime in this situation.
protected void Page_Load(object sender, EventArgs e)
{
grid.RowDataBound += grid_RowDataBound;
// Your DB access code here...
// grid.DataSource = cmd.ExecuteReader(CommandBehavior.CloseConnection);
// grid.DataBind();
}
void grid_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow)
return;
var dt = (e.Row.DataItem as DbDataRecord).GetDateTime(4);
e.Row.Cells[4].Text = dt.ToString("dd.MM.yyyy");
}
The results shown here.
Just to add a couple of points:
Because the Validate()
method signature returns IEnumerable<>
, that yield return
can be used to lazily generate the results - this is beneficial if some of the validation checks are IO or CPU intensive.
public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
{
if (this.Enable)
{
// ...
if (this.Prop1 > this.Prop2)
{
yield return new ValidationResult("Prop1 must be larger than Prop2");
}
Also, if you are using MVC ModelState
, you can convert the validation result failures to ModelState
entries as follows (this might be useful if you are doing the validation in a custom model binder):
var resultsGroupedByMembers = validationResults
.SelectMany(vr => vr.MemberNames
.Select(mn => new { MemberName = mn ?? "",
Error = vr.ErrorMessage }))
.GroupBy(x => x.MemberName);
foreach (var member in resultsGroupedByMembers)
{
ModelState.AddModelError(
member.Key,
string.Join(". ", member.Select(m => m.Error)));
}
i think it always boils to the classpath
. having said that if you run from the same folder where your .class is then change Scanner input = new Scanner(new File("word.txt"));
to Scanner input = new Scanner(new File("./word.txt"));
that should work
This is a one line solution involving LINQ.
var elements = new String[] { "1", "2", "3" };
Foo(elements.Cast<object>().ToArray())
In the "Welcome to Android Studio" opening dialog you can highlight the app you want to remove from Android Studio and hit delete on your keyboard.
Swift Array performance revisited:
I wrote my own benchmark comparing Swift with C/Objective-C. My benchmark calculates prime numbers. It uses the array of previous prime numbers to look for prime factors in each new candidate, so it is quite fast. However, it does TONS of array reading, and less writing to arrays.
I originally did this benchmark against Swift 1.2. I decided to update the project and run it against Swift 2.0.
The project lets you select between using normal swift arrays and using Swift unsafe memory buffers using array semantics.
For C/Objective-C, you can either opt to use NSArrays, or C malloc'ed arrays.
The test results seem to be pretty similar with fastest, smallest code optimization ([-0s]) or fastest, aggressive ([-0fast]) optimization.
Swift 2.0 performance is still horrible with code optimization turned off, whereas C/Objective-C performance is only moderately slower.
The bottom line is that C malloc'd array-based calculations are the fastest, by a modest margin
Swift with unsafe buffers takes around 1.19X - 1.20X longer than C malloc'd arrays when using fastest, smallest code optimization. the difference seems slightly less with fast, aggressive optimization (Swift takes more like 1.18x to 1.16x longer than C.
If you use regular Swift arrays, the difference with C is slightly greater. (Swift takes ~1.22 to 1.23 longer.)
Regular Swift arrays are DRAMATICALLY
faster than they were in Swift 1.2/Xcode 6. Their performance is so close to Swift unsafe buffer based arrays that using unsafe memory buffers does not really seem worth the trouble any more, which is big.
BTW, Objective-C NSArray performance stinks. If you're going to use the native container objects in both languages, Swift is DRAMATICALLY faster.
You can check out my project on github at SwiftPerformanceBenchmark
It has a simple UI that makes collecting stats pretty easy.
It's interesting that sorting seems to be slightly faster in Swift than in C now, but that this prime number algorithm is still faster in Swift.
Use the ng-click
directive:
<button my-directive ng-click="alertFn()">Click Me!</button>
// In <script>:
app.directive('myDirective' function() {
return function(scope, element, attrs) {
scope.alertFn = function() { alert('click'); };
};
};
Note that you don't need my-directive
in this example, you just need something to bind alertFn
on the current scope.
Update:
You also want the angular libraries loaded before your <script>
block.
I just want to mention the great AssertJ library. It's my go to assertion library for JUnit 4 and 5 and also solves this problem elegantly:
assertThat(actual).isCloseTo(expectedDouble, within(delta))
The one above only runs for "One File" only, but you can also run this for multiple files within your folder:
Get-ChildItem 'C:yourfile*.xml' -Recurse | ForEach {
(Get-Content $_ | ForEach { $_ -replace '[MYID]', 'MyValue' }) |
Set-Content $_
}
Use a subquery:
SELECT * FROM (
SELECT * FROM users ORDER BY RAND() LIMIT 20
) u
ORDER BY name
or a join to itself:
SELECT * FROM users u1
INNER JOIN (
SELECT id FROM users ORDER BY RAND() LIMIT 20
) u2 USING(id)
ORDER BY u1.name
Sometimes changes made to the model or to the ORM may not reflect accurately on the database even after an execution of SchemaUpdate
.
If the error actually seems to lack a sensible explanation, try recreating the database (or at least creating a new one) and scaffolding it with SchemaExport
.
ZedGraph is a good choice.
You can use list comprehension:
res_list = [i[0] for i in rows]
This should make the trick
You can't import classes from the default package. You should avoid using the default package except for very small example programs.
From the Java language specification:
It is a compile time error to import a type from the unnamed package.
I had this problem even after following the accepted answer and found the following to work:
In your Info.plist, add an entry for Required Device Capabilities. This should be an array and will have two entries.
It will look like this:
With Python 2, this doesn't work for non-English words in UTF-8. In this case decode('utf-8')
can help:
>>> s='????????'
>>> print s.lower()
????????
>>> print s.decode('utf-8').lower()
????????
When you create a cookie via PHP die Default Value is 0, from the manual:
If set to 0, or omitted, the cookie will expire at the end of the session (when the browser closes)
Otherwise you can set the cookies lifetime in seconds as the third parameter:
http://www.php.net/manual/en/function.setcookie.php
But if you mean to get the remaining lifetime of an already existing cookie, i fear that, is not possible (at least not in a direct way).
I have used below code in Angular 9. note that it is using http class instead of normal httpClient.
so import Headers from the module, otherwise Headers will be mistaken by typescript headers interface and gives error
import {Http, Headers, RequestOptionsArgs } from "@angular/http";
and in your method use following sample code and it is breaked down for easier understanding.
let customHeaders = new Headers({ Authorization: "Bearer " + localStorage.getItem("token")});
const requestOptions: RequestOptionsArgs = { headers: customHeaders };
return this.http.get("/api/orders", requestOptions);
You can skip the var declaration and the stringify. Otherwise, that will work just fine.

You could build your form using FormBuilder as it let you more flexible way to configure form.
export class MyComp {
form: ControlGroup;
constructor(@Inject()fb: FormBuilder) {
this.form = fb.group({
foo: ['', MyValidators.regex(/^(?!\s|.*\s$).*$/)]
});
}
Then in your template :
<input type="text" ngControl="foo" />
<div *ngIf="!form.foo.valid">Please correct foo entry !</div>
You can also customize ng-invalid CSS class.
As there is actually no validators for regex, you have to write your own. It is a simple function that takes a control in input, and return null if valid or a StringMap if invalid.
export class MyValidators {
static regex(pattern: string): Function {
return (control: Control): {[key: string]: any} => {
return control.value.match(pattern) ? null : {pattern: true};
};
}
}
Hope that it help you.

jQuery's data()
method will give you access to data-*
attributes, BUT, it clobbers the case of the attribute name. You can either use this:
$('#myButton').data("x10") // note the lower case
Or, you can use the attr()
method, which preserves your case:
$('#myButton').attr("data-X10")
Try both methods here: http://jsfiddle.net/q5rbL/
Be aware that these approaches are not completely equivalent. If you will change the data-*
attribute of an element, you should use attr()
. data()
will read the value once initially, then continue to return a cached copy, whereas attr()
will re-read the attribute each time.
Note that jQuery will also convert hyphens in the attribute name to camel case (source -- i.e. data-some-data == $(ele).data('someData')
). Both of these conversions are in conformance with the HTML specification, which dictates that custom data attributes should contain no uppercase letters, and that hyphens will be camel-cased in the dataset
property (source). jQuery's data
method is merely mimicking/conforming to this standard behavior.
Documentation
data
- http://api.jquery.com/data/attr
- http://api.jquery.com/attr/Other answers suggest how to get a floating-point value. While this wlil be close to what you want, it won't be exact:
>>> 0.4/100.
0.0040000000000000001
If you actually want a decimal value, do this:
>>> import decimal
>>> decimal.Decimal('4') / decimal.Decimal('100')
Decimal("0.04")
That will give you an object that properly knows that 4 / 100 in base 10 is "0.04". Floating-point numbers are actually in base 2, i.e. binary, not decimal.
For simple commands you can use:
ssh <ssh_args> command1 '&&' command2
or
ssh <ssh_args> command1 \&\& command2

Most of the answers found here are correct only if you need the current year based on your local machine's time zone and offset (client side) - source which, in most scenarios, cannot be considered reliable (beause it can differ from machine to machine).
Reliable sources are:
A method called on the Date
instance will return a value based on the local time of your machine.
Further details can be found in "MDN web docs": JavaScript Date object.
For your convenience, I've added a relevant note from their docs:
(...) the basic methods to fetch the date and time or its components all work in the local (i.e. host system) time zone and offset.
Another source mentioning this is: JavaScript date and time object
it is important to note that if someone's clock is off by a few hours or they are in a different time zone, then the Date object will create a different times from the one created on your own computer.
Some reliable sources that you can use are:
But if you simply don't care about the time accuracy or if your use case requires a time value relative to local machine's time then you can safely use Javascript's Date
basic methods like Date.now()
, or new Date().getFullYear()
(for current year).

I guess MySQL doesn't believe this to be valid UTF8 text. I tried an insert on a test table with the same column definition (mysql client connection was also UTF8) and although it did the insert, the data I retrieved with the MySQL CLI client as well as JDBC didn't retrieve the values correctly. To be sure UTF8 did work correctly, I inserted an "ö" instead of an "o" for obama:

Also, I've tried the same insert with the JDBC connection and it threw the same exception you are getting. I believe this to be a MySQL bug. Maybe there's a bug report about such a situation already..
I Dont Knew Which one Is Optimized (compared to @AdaTheDev ) but This one seems to be quicker when I use (atleast for me)
SELECT id FROM table_1 EXCEPT SELECT DISTINCT (table1_id) table1_id FROM table_2
If You want to get any other specific attribute you can use:
SELECT COUNT(*) FROM table_1 where id in (SELECT id FROM table_1 EXCEPT SELECT DISTINCT (table1_id) table1_id FROM table_2);
I tried this out for transmitting continuous data (float values converted to string) from my PC (MATLAB) to my phone. But, still my App misreads the delimiter '\n' and still data gets garbled. So, I took the character 'N' as the delimiter rather than '\n' (it could be any character that doesn't occur as part of your data) and I've achieved better transmission speed - I gave just 0.1 seconds delay between transmitting successive samples - with more than 99% data integrity at the receiver i.e. out of 2000 samples (float values) that I transmitted, only 10 were not decoded properly in my application.
My answer in short is: Choose a delimiter other than '\r' or '\n' as these create more problems for real-time data transmission when compared to other characters like the one I've used. If we work more, may be we can increase the transmission rate even more. I hope my answer helps someone!
Cast the operands to floats:
float ans = (float)a / (float)b;
gnu tar v 1.26 the --exclude needs to come after archive file and backup directory arguments, should have no leading or trailing slashes, and prefers no quotes (single or double). So relative to the PARENT directory to be backed up, it's:
tar cvfz /path_to/mytar.tgz ./dir_to_backup --exclude=some_path/to_exclude
I have implemented a custom controller that dynamically calculates the size of the keyboard, scrolling textFields when it appears and disappears, even during rotation of the device. Works with all iOS devices. Just simply inherit the controller to have what you need. You can find it with all the instructions at the following link: https://github.com/mikthebig/ios-textfield-scroll
It can indeed depends on how the layout is defined. But to ensure that the dialog gets the required size, the best solution is to provide the LayoutParams once the dialog is shown (and not on creation). On a DialogFragment the dialog is shown on the onStart method, so a valid method to get full width is:
@Override public void onStart() {
super.onStart();
Dialog d = getDialog();
if (d!=null){
d.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
}
}
To also provide a theme, or style, like a NO_TITLE style, the best location is on the onCreate method:
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(STYLE_NO_TITLE, android.R.style.Theme_Holo_Light_Dialog);
}
If you want the style to apply globally you could use the adjacent sibling combinator from css.
.my-button-style + .my-button-style {
margin-left: 40px;
}
/* general button style */
.my-button-style {
height: 100px;
width: 150px;
}
Here is a fiddle: https://jsfiddle.net/caeLosby/10/
It is similar to some of the existing answers but it does not set the margin on the first button. For example in the case
<button id="btn1" class="my-button-style"/>
<button id="btn2" class="my-button-style"/>
only btn2
will get the margin.
For further information see https://developer.mozilla.org/en-US/docs/Web/CSS/Adjacent_sibling_combinator
An int
is a 32-bit integer; a long
is a 64-bit integer. Which one to use depends on how large the numbers are that you expect to work with.
int
and long
are primitive types, while Integer
and Long
are objects. Primitive types are more efficient, but sometimes you need to use objects; for example, Java's collection classes can only work with objects, so if you need a list of integers you have to make it a List<Integer>
, for example (you can't use int
in a List
directly).
If you are on windows and using mingw, gcc uses the win32 runtime, where printf needs %I64d
for a 64 bit integer. (and %I64u
for an unsinged 64 bit integer)
For most other platforms you'd use %lld
for printing a long long. (and %llu
if it's unsigned). This is standarized in C99.
gcc doesn't come with a full C runtime, it defers to the platform it's running on - so the general case is that you need to consult the documentation for your particular platform - independent of gcc.
You can use the spread operator to convert Map.keys() iterator in an Array.
let myMap = new Map().set('a', 1).set('b', 2).set(983, true)_x000D_
let keys = [...myMap.keys()]_x000D_
console.log(keys)
_x000D_
Python compiles the .py
and saves files as .pyc
so it can reference them in subsequent invocations.
There's no harm in deleting them, but they will save compilation time if you're doing lots of processing.
In PostreSQL you can use SIMILAR TO operator (more):
-- only digits
select * from books where title similar to '^[0-9]*$';
-- start with digit
select * from books where title similar to '^[0-9]%$';
Additionally, you can use Google CityHash:

You can not add a reference to a native DLL. However You can include them in the solution (right click solution, select "Add existing file"), but they will not be referenced unless you declare something like
[DllImport("...")]
public static extern void MyFunction();
Maybe there's some kind of wrapper DLL, which you are actually referencing and which contains the DLL imports.
Sometimes, You may reference the wrapper DLL but still can not make your program running, where error prompt suggests you to ensure the file exists and all dependencies are available.
This problem is because the assembly you are trying to add is targeted and compiled only for a x86 or x64 processor architecture.
Just try change the Target Platform to x86 or x64 in Build -> Configuration Manager.
tl;dr non-capturing groups, as the name suggests are the parts of the regex that you do not want to be included in the match and ?:
is a way to define a group as being non-capturing.
Let's say you have an email address [email protected]
. The following regex will create two groups, the id part and @example.com part. (\p{Alpha}*[a-z])(@example.com)
. For simplicity's sake, we are extracting the whole domain name including the @
character.
Now let's say, you only need the id part of the address. What you want to do is to grab the first group of the match result, surrounded by ()
in the regex and the way to do this is to use the non-capturing group syntax, i.e. ?:
. So the regex (\p{Alpha}*[a-z])(?:@example.com)
will return just the id part of the email.
In Elasticsearch 5.x the above mentioned approach is deprecated. You can use the _source approach, but but in certain situations it can make sense to store a field. For instance, if you have a document with a title, a date, and a very large content field, you may want to retrieve just the title and the date without having to extract those fields from a large _source field:
In this case, you'd use:
{
"size": $INT_NUM_OF_DOCS_TO_RETURN,
"stored_fields":[
"doc.headline",
"doc.text",
"doc.timestamp_utc"
],
"query":{
"bool":{
"must":{
"term":{
"doc.topic":"news_on_things"
}
},
"filter":{
"range":{
"doc.timestamp_utc":{
"gte":1451606400000,
"lt":1483228800000,
"format":"epoch_millis"
}
}
}
}
},
"aggs":{
}
}
See the documentation on how to index stored fields. Always happy for an Upvote!

Below is code to break a loop in a simple way
import scala.util.control.Breaks.break
object RecurringCharacter {
def main(args: Array[String]) {
val str = "nileshshinde";
for (i <- 0 to str.length() - 1) {
for (j <- i + 1 to str.length() - 1) {
if (str(i) == str(j)) {
println("First Repeted Character " + str(i))
break() //break method will exit the loop with an Exception "Exception in thread "main" scala.util.control.BreakControl"
}
}
}
}
}
Analoguously to the two options (homebrew / manual) posted by @brismuth, here's the MacPorts way:
Install the Android SDK:
sudo port install android
Run the SDK manager:
sh /opt/local/share/java/android-sdk-macosx/tools/android
As @brismuth suggested, uncheck everything but Android SDK Platform-tools
(optional)
Install the packages, accepting licenses. Close the SDK Manager.
Add platform-tools
to your path; in MacPorts, they're in /opt/local/share/java/android-sdk-macosx/platform-tools
. E.g., for bash:
echo 'export PATH=$PATH:/opt/local/share/java/android-sdk-macosx/platform-tools' >> ~/.bash_profile
Refresh your bash profile (or restart your terminal/shell):
source ~/.bash_profile
Start using adb:
adb devices
@gnomixa - What do you mean in your comment about not achieving anything? The following works for me in VS2005.
If your goal is to remove the newline characters, thereby shortening the string, look at this:
string originalStringWithNewline = "12\n345"; // length is 6
System.Diagnostics.Debug.Assert(originalStringWithNewline.Length == 6);
string newStringWithoutNewline = originalStringWithNewline.Replace("\n", ""); // new length is 5
System.Diagnostics.Debug.Assert(newStringWithoutNewline.Length == 5);
If your goal is to replace the newline characters with a space character, leaving the string length the same, look at this example:
string originalStringWithNewline = "12\n345"; // length is 6
System.Diagnostics.Debug.Assert(originalStringWithNewline.Length == 6);
string newStringWithoutNewline = originalStringWithNewline.Replace("\n", " "); // new length is still 6
System.Diagnostics.Debug.Assert(newStringWithoutNewline.Length == 6);
And you have to replace single-character strings instead of characters because '' is not a valid character to be passed to Replace(string,char)
I also wouldn't call two many (is_a?
and kind_of?
are aliases of the same method), but if you want to see more possibilities, turn your attention to #class
method:
A = Class.new
B = Class.new A
a, b = A.new, B.new
b.class < A # true - means that b.class is a subclass of A
a.class < B # false - means that a.class is not a subclass of A
# Another possibility: Use #ancestors
b.class.ancestors.include? A # true - means that b.class has A among its ancestors
a.class.ancestors.include? B # false - means that B is not an ancestor of a.class

There is no show
event in js - you need to bind your button either to the click
event:
$('#id').on('click', function (e) {
//your awesome code here
})
Mind that if your button is inside a form
, you may prefer to bind the whole form to the submit
event.
Port 4200 is already in use. Use '--port' to specify a different port
This means that you already have another service running on port 4200. If this is the case
you can either . shut down the other service. use the --port
flag when running ng
serve like this:
ng serve --port 9001
Another thing to notice is that, on some machines, the domain localhost may not work. You may see a set of numbers such as 127.0.0.1. When you run ng serve it should show you what URL the server is running on, so be sure to read the messages on your machine to find your exact development URL.
Yes this is possible. kizzie is correct with the session_start();
having to go first.
another observation I made is that you need to filter your form data using:
strip_tags($value);
and/or
stripslashes($value);
If you want something more similar to your example try _itot_s. On Microsoft compilers _itot_s points to _itoa_s or _itow_s depending on your Unicode setting:
CString str;
_itot_s( 15, str.GetBufferSetLength( 40 ), 40, 10 );
str.ReleaseBuffer();
it should be slightly faster since it doesn't need to parse an input format.
The data.table
package introduced the IDate
class some time ago and zoo
-package-like functions to retrieve months, days, etc (Check ?IDate
). so, you can extract the desired info now in the following ways:
require(data.table)
df <- data.frame(id = 1:3,
date = c("2004-02-06" , "2006-03-14" , "2007-07-16"))
setDT(df)
df[ , date := as.IDate(date) ] # instead of as.Date()
df[ , yrmn := paste0(year(date), '-', month(date)) ]
df[ , yrmn2 := format(date, '%Y-%m') ]
You could do $stmt->queryString
to obtain the SQL query used in the statement. If you want to save the entire $stmt variable (I can't see why), you could just copy it. It is an instance of PDOStatement so there is apparently no advantage in storing it.
ARGH!
I found it... I didn't have an extra package, called Microsoft.Owin.Host.SystemWeb
Once i searched and installed this, it worked.
Now - i am not sure if i just missed everything, though found NO reference to such a library or package when going through various tutorials. It also didn't get installed when i installed all this Identity framework... Not sure if it were just me..
EDIT
Although it's in the Microsoft.Owin.Host.SystemWeb
assembly it is an extension method in the System.Web
namespace, so you need to have the reference to the former, and be using
the latter.
Here is a one-off way to do this, which is useful if you don't want to change your default settings:
def fullprint(*args, **kwargs):
from pprint import pprint
import numpy
opt = numpy.get_printoptions()
numpy.set_printoptions(threshold=numpy.inf)
pprint(*args, **kwargs)
numpy.set_printoptions(**opt)
You can build docker image from a file called docker file and named Dockerfile by default. It has set of command/instruction that you need in your docker container. Below command creates image with tag latest, Dockerfile should present on that location (. means present direcotry)
docker build . -t <image_name>:latest
You can specify the Dockerfile via -f if the file name in not default (Dockerfile) Sameple Docker file contents.

You may use this function. To add table header you can setup a second parameter $myTableArrayHeader
and do the same with the header information in front of the body:
function insertTable($myTableArrayBody) {
$x = 0;
$y = 0;
$seTableStr = '<table><tbody>';
while (isset($myTableArrayBody[$y][$x])) {
$seTableStr .= '<tr>';
while (isset($myTableArrayBody[$y][$x])) {
$seTableStr .= '<td>' . $myTableArrayBody[$y][$x] . '</td>';
$x++;
}

Such thing is easy with ggplot2
library(ggplot2)
dataset <- data.frame(X = c(rep(65, times=5), rep(25, times=5),
rep(35, times=10), rep(45, times=4)))
ggplot(dataset, aes(x = X)) +
geom_histogram(aes(y = ..density..)) +
geom_density()
or to mimic the result from Dirk's solution
ggplot(dataset, aes(x = X)) +
geom_histogram(aes(y = ..density..), binwidth = 5) +
geom_density()
its working with this code
