I got the same message but my files are decrypted as expected. Please check in your destination path if you could see the output file file.
It is fast. Try it:
DELETE FROM YourTABLE
FROM (SELECT TOP XX PK FROM YourTABLE) tbl
WHERE YourTABLE.PK = tbl.PK
Replace YourTABLE
by table name,
XX
by a number, for example 1000,
pk
is the name of the primary key field of your table.
We have the following string which is a valid JSON ...
Clearly the JSON parser disagrees!
However, the exception says that the error is at "line 1: column 9", and there is no "http" token near the beginning of the JSON. So I suspect that the parser is trying to parse something different than this string when the error occurs.
You need to find what JSON is actually being parsed. Run the application within a debugger, set a breakpoint on the relevant constructor for JsonParseException
... then find out what is in the ByteArrayInputStream
that it is attempting to parse.
The shortest and fastest way ever. Only 1 line!
public static string StringSha256Hash(string text) =>
string.IsNullOrEmpty(text) ? string.Empty : BitConverter.ToString(new System.Security.Cryptography.SHA256Managed().ComputeHash(System.Text.Encoding.UTF8.GetBytes(text))).Replace("-", string.Empty);
Adding a shell script e.g. run.sh
makes it much more easier:
#!/usr/bin/env bash
export JAVA_PROGRAM_ARGS=`echo "$@"`
mvn exec:java -Dexec.mainClass="test.Main" -Dexec.args="$JAVA_PROGRAM_ARGS"
Then you are able to execute:
./run.sh arg1 arg2 arg3
If you are using eclipse plugin, double click on the app-name in My Heroku Applications. In Processes tab, press Scale Button. A small window will pop-up. Increase/decrease the count and just say OK.
You can use a Dictionary to keep track of the keys and values.
For instance...
dictOfStuff = {} ##Make a Dictionary
x = "Buffalo" ##OR it can equal the input of something, up to you.
dictOfStuff[x] = 4 ##Get the dict spot that has the same key ("name") as what X is equal to. In this case "Buffalo". and set it to 4. Or you can set it to what ever you like
print(dictOfStuff[x]) ##print out the value of the spot in the dict that same key ("name") as the dictionary.
A dictionary is very similar to a real life dictionary. You have a word and you have a definition. You can look up the word and get the definition. So in this case, you have the word "Buffalo" and it's definition is 4. It can work with any other word and definition. Just make sure you put them into the dictionary first.
OK so I created a static async method. That disabled the control that launches the action and changes the application cursor. It runs the action as a task and waits for to finish. Control returns to the caller while it waits. So the application remains responsive, even while the busy icon spins.
async public static void LengthyOperation(Control control, Action action)
{
try
{
control.Enabled = false;
Application.UseWaitCursor = true;
Task doWork = new Task(() => action(), TaskCreationOptions.LongRunning);
Log.Info("Task Start");
doWork.Start();
Log.Info("Before Await");
await doWork;
Log.Info("After await");
}
finally
{
Log.Info("Finally");
Application.UseWaitCursor = false;
control.Enabled = true;
}
Here's the code form the main form
private void btnSleep_Click(object sender, EventArgs e)
{
var control = sender as Control;
if (control != null)
{
Log.Info("Launching lengthy operation...");
CursorWait.LengthyOperation(control, () => DummyAction());
Log.Info("...Lengthy operation launched.");
}
}
private void DummyAction()
{
try
{
var _log = NLog.LogManager.GetLogger("TmpLogger");
_log.Info("Action - Sleep");
TimeSpan sleep = new TimeSpan(0, 0, 16);
Thread.Sleep(sleep);
_log.Info("Action - Wakeup");
}
finally
{
}
}
I had to use a separate logger for the dummy action (I am using Nlog) and my main logger is writing to the UI (a rich text box). I wasn't able to get the busy cursor show only when over a particular container on the form (but I didn't try very hard.) All controls have a UseWaitCursor property, but it doesn't seem have any effect on the controls I tried (maybe because they weren't on top?)
Here's the main log, which shows things happening in the order we expect:
16:51:33.1064 Launching lengthy operation...
16:51:33.1215 Task Start
16:51:33.1215 Before Await
16:51:33.1215 ...Lengthy operation launched.
16:51:49.1276 After await
16:51:49.1537 Finally
Although I was expecting an automatic solution (fitting to the screen automatically), resizing solves the problem as well.
import cv2
cv2.namedWindow("output", cv2.WINDOW_NORMAL) # Create window with freedom of dimensions
im = cv2.imread("earth.jpg") # Read image
imS = cv2.resize(im, (960, 540)) # Resize image
cv2.imshow("output", imS) # Show image
cv2.waitKey(0) # Display the image infinitely until any keypress
Just for the kicks.
Since I wasnt able to create linked server and since just connecting to production server was not enough to use INSERT INTO
i did the following:
Its a backdoor solution, but since i had problems it worked for me.
Since i have created empty tables using SCRIPT TABLE AS / CREATE
in order to transfer all the keys and indexes I couldnt use SELECT INTO
. SELECT INTO
only works if the tables do not exist on the destination location but it does not copy keys and indexes, so you have to do that manualy. The downside of using INSERT INTO
statement is that you have to manualy provide with all the column names, plus it might give you some problems if some foreign key constraints fail.
Thanks to all anwsers, there are some great solutions but i have decided to accept marc_s anwser.
Thanks Ravi and other users .... Nevertheless I have got the solution
SELECT @phoneNumber=
CASE
WHEN ISNULL(rdg2.nPhoneNumber ,'0') in ('0','-',NULL)
THEN ISNULL(rdg2.nMobileNumber, '0')
WHEN ISNULL(rdg2.nMobileNumber, '0') in ('0','-',NULL)
THEN '0'
ELSE ISNULL(rdg2.nPhoneNumber ,'0')
END
FROM tblReservation_Details_Guest rdg2
WHERE nReservationID=@nReservationID
Just need to put '0' instead of 0
IRI (RFC 3987) is the latest standard that replaces the URI/URL (RFC 3986 and older) standards. URI/URL do not natively support Unicode (well, RFC 3986 adds provisions for future URI/URL-based protocols to support it, but does not update past RFCs). The "%uXXXX" scheme is a non-standard extension to allow Unicode in some situations, but is not universally implemented by everyone. IRI, on the other hand, fully supports Unicode, and requires that text be encoded as UTF-8 before then being percent-encoded.
if you are using webview inside a fragment than use this in your onCreateView method
webView.setOnKeyListener(new View.OnKeyListener(){
@Override
public boolean onKey(View view, int i, KeyEvent keyEvent) {
if((i==KeyEvent.KEYCODE_BACK)&& webView.canGoBack()){
webView.goBack();
return true;
}
return false;
}
});
and import this class
import android.view.KeyEvent;
Despite the fact that this question has been answered long time ago, I found some interesting facts to add that are related to the answers above.
As Dirk mentioned, there seems to be a weird fashion of version control from MS, starting from Office 365 / 2019. You cannot distinguish among the three(2016, 2019, O365), by seeing at the executable paths anymore. And just like he reputed himself, looking at the builds of the executable, as a mean of telling which is what, isn't quite effective either.
After some researching, I found a feasible solution. The solution lies under the registry subkey Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Licensing\LicensingNext
.
So, my logic follows below:
Case 1: If the computer has the MSOffice 2016 installed, there is no subkeys under Licensing
.
Case 2: if the computer has MSOffice 2019 installed, there is the name of the value (which is one of the Office Product ID). (e.g. Standard2019Volume
)
Case 3: if the computer has Office365 installed, there is a value called o365bussinessretail
(which is also a product ID) along with some other values.
The possible productIds are provided here.
To distinguish the three, I just opened the key and see if fails. If the open fails, its Office 2016. Then I enumerate LicensingNext
and try to see if any name has a prefix o365
, if it finds it then its O365. If it does not, then its Office 2019.
Frankly speaking, I did not have enough time to test the logic under varying environment. So please, note that.
Hope this will help whoever's interest.
A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.
This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.
Whereas a GridLayout is a layout that places its children in a rectangular grid.
It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.
This is the easiest one , Just define a Function and then a Tkinter Label & Button . Pressing the Button changes the text in the label. The difference that you would when defining the Label is that use the text variable instead of text. Code is tested and working.
from tkinter import *
master = Tk()
def change_text():
my_var.set("Second click")
my_var = StringVar()
my_var.set("First click")
label = Label(mas,textvariable=my_var,fg="red")
button = Button(mas,text="Submit",command = change_text)
button.pack()
label.pack()
master.mainloop()
Also make sure that the AppStore distribution of the app is not also installed on the device.
Based on the hint and link provided in Simone Giannis answer, this is my hack to fix this.
I am testing on uri.getAuthority(), because UNC path will report an Authority. This is a bug - so I rely on the existence of a bug, which is evil, but it apears as if this will stay forever (since Java 7 solves the problem in java.nio.Paths).
Note: In my context I will receive absolute paths. I have tested this on Windows and OS X.
(Still looking for a better way to do it)
package com.christianfries.test;

URI uri = url.toURI();
System.out.println("URI is: " + uri.toString());
if(uri.getAuthority() != null && uri.getAuthority().length() > 0) {
// Hack for UNC Path
uri = (new URL("file://" + urlString.substring("file:".length()))).toURI();
}
File file = new File(uri);
System.out.println("File is: " + file.toString());

>>> a = {'foo': 'bar', 'baz': 'quux', 'hello': 'world'}
>>> list(reduce(lambda x, y: x + y, a.items()))
['foo', 'bar', 'baz', 'quux', 'hello', 'world']
To explain: a.items() returns a list of tuples. Adding two tuples together makes one tuple containing all elements. Thus the reduction creates one tuple containing all keys and values and then the list(...) makes a list from that.
I am also working with Laravel and I like the implementation there. I tried to mimic it and combining it with the solution proposed by T. Stone (look above):
PRODUCTION_SERVERS = ['*.webfaction.com','*.whatever.com',]
def check_env():
for item in PRODUCTION_SERVERS:
match = re.match(r"(^." + item + "$)", socket.gethostname())
if match:
return True
if check_env():
PRODUCTION = True
else:
PRODUCTION = False
DEBUG = not PRODUCTION

You need to Open the output file for write access rather than using a new StreamReader, which always overwrites the output file.
StreamWriter stm = null;
fi = new FileInfo(@"C:\target.xml");
if (fi.Exists)
stm = fi.OpenWrite();
Of course, you will still have to seek to the correct line in the output file, which will be hard since you can't read from it, so unless you already KNOW the byte offset to seek to, you probably really want read/write access.
FileStream stm = fi.Open(FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.None);
with this stream, you can read until you get to the point where you want to make changes, then write. Keep in mind that you are writing bytes, not lines, so to overwrite a line you will need to write the same number of characters as the line you want to change.
Example for Spring Boot. My WSDL-file is in Resources in "wsdl" folder. The path to the WSDL-file is:
resources/wsdl/WebServiceFile.wsdl
To get the path from some method to this file you can do the following:
String pathToWsdl = this.getClass().getClassLoader().
getResource("wsdl\\WebServiceFile.wsdl").toString();
There are 2 potential issues that I see:
1 - IE has had trouble with position:fixed in the past. If you are using IE7+ with a valid doctype or a non-IE browser this isn't part of the problem
2 - You need to specify a width for the footer if you want the footer object to be centered. Otherwise it defaults to the full width of the page and the auto margin for the left and right get set to 0. If you want the footer bar to take up the width (like the StackOverflow notice bar) and center the text, then you need to add "text-align: center" to your definition.
Just to clarify the Training/Validation/Test data sets: The training set is used to perform the initial training of the model, initializing the weights of the neural network.
The validation set is used after the neural network has been trained. It is used for tuning the network's hyperparameters, and comparing how changes to them affect the predictive accuracy of the model. Whereas the training set can be thought of as being used to build the neural network's gate weights, the validation set allows fine tuning of the parameters or architecture of the neural network model. It's useful as it allows repeatable comparison of these different parameters/architectures against the same data and networks weights, to observe how parameter/architecture changes affect the predictive power of the network.
Then the test set is used only to test the predictive accuracy of the trained neural network on previously unseen data, after training and parameter/architecture selection with the training and validation data sets.
Interpreted language is executed at the run time according to the instructions like in shell scripting and compiled language is one which is compiled (changed into Assembly language, which CPU can understand ) and then executed like in c++.
Based on the fact that longitude lines are spaced apart equally at any point of the map, there is a very simple implementation to set the centerCoordinate and zoomLevel:
@interface MKMapView (ZoomLevel)
@property (assign, nonatomic) NSUInteger zoomLevel;
- (void)setCenterCoordinate:(CLLocationCoordinate2D)centerCoordinate
zoomLevel:(NSUInteger)zoomLevel
animated:(BOOL)animated;
@end
@implementation MKMapView (ZoomLevel)
- (void)setZoomLevel:(NSUInteger)zoomLevel {
[self setCenterCoordinate:self.centerCoordinate zoomLevel:zoomLevel animated:NO];
}
- (NSUInteger)zoomLevel {
return log2(360 * ((self.frame.size.width/256) / self.region.span.longitudeDelta)) + 1;
}
- (void)setCenterCoordinate:(CLLocationCoordinate2D)centerCoordinate
zoomLevel:(NSUInteger)zoomLevel animated:(BOOL)animated {
MKCoordinateSpan span = MKCoordinateSpanMake(0, 360/pow(2, zoomLevel)*self.frame.size.width/256);
[self setRegion:MKCoordinateRegionMake(centerCoordinate, span) animated:animated];
}
@end
$ git config --global alias.cleanup
'!git branch --merged origin/master | egrep -v "(^\*|master|staging|dev)" | xargs git branch -d'
(Split into multiple lines for readability)
Calling "git cleanup" will delete local branches that have already been merged into origin/master. It skips master, staging, and dev because we don't want to delete those in normal circumstances.
Breaking this down, this is what it's doing:
git config --global alias.cleanup
!
at the beginning of the command is saying that we will be using some non-git commands as part of this alias so we need to actually run bash commands heregit branch --merged origin/master
origin/master
egrep -v "(^\*|master|staging|dev)"
xargs git branch -d
git branch -d xxxxx
command for each of the unmerged branches. This deletes the local branches one by one.Had the same issue today and found another option with knitr 1.16
when knitting to PDF (which requires that you have pandoc installed):
![Image Title](path/to/your/image){width=70%}
This method may require that you do a bit of trial and error to find the size that works for you. It is especially convenient because it makes putting two images side by side a prettier process. For example:
![Image 1](path/to/image1){width=70%}![Image 2](path/to/image2){width=30%}
You can get creative and stack a couple of these side by side and size them as you see fit. See https://rpubs.com/RatherBit/90926 for more ideas and examples.
What's the difference between an RDD's map and mapPartitions method?
The method map converts each element of the source RDD into a single element of the result RDD by applying a function. mapPartitions converts each partition of the source RDD into multiple elements of the result (possibly none).
And does flatMap behave like map or like mapPartitions?
Neither, flatMap works on a single element (as map
) and produces multiple elements of the result (as mapPartitions
).
class A{
public:
static const char* SOMETHING() { return "something"; }
};
I do it all the time - especially for expensive const default parameters.
class A{
static
const expensive_to_construct&
default_expensive_to_construct(){
static const expensive_to_construct xp2c(whatever is needed);
return xp2c;
}
};
Possible solution for GET requests:
New Link format: http://example.com/yourDirectory?hash=video01
Call this function toward top of controller or http://example.com/yourDirectory/index.php
:
function redirect()
{
if (!empty($_GET['hash'])) {
/** Sanitize & Validate $_GET['hash']
If valid return string
If invalid: return empty or false
******************************************************/
$validHash = sanitizeAndValidateHashFunction($_GET['hash']);
if (!empty($validHash)) {
$url = './#' . $validHash;
} else {
$url = '/your404page.php';
}
header("Location: $url");
}
}
Only use git rm --cached [file]
to remove a file from the index.
git reset <filename>
can be used to remove added files from the index given the files are never committed.
% git add First.txt
% git ls-files
First.txt
% git commit -m "First"
% git ls-files
First.txt
% git reset First.txt
% git ls-files
First.txt
NOTE: git reset First.txt
has no effect on index after the commit.
Which brings me to the topic of git restore --staged <file>
. It can be used to (presumably after the first commit) remove added files from the index given the files are never committed.
% git add Second.txt
% git status
On branch master
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
new file: Second.txt
% git ls-files
First.txt
Second.txt
% git restore --staged Second.txt
% git ls-files
First.txt
% git add Second.txt
% git commit -m "Second"
% git status
On branch master
nothing to commit, working tree clean
% git ls-files
First.txt
Second.txt
Desktop/Test% git restore --staged .
Desktop/Test% git ls-files
First.txt
Second.txt
Desktop/Test% git reset .
Desktop/Test% git ls-files
First.txt
Second.txt
% git rm --cached -r .
rm 'First.txt'
rm 'Second.txt'
% git ls-files
tl;dr Look at last 15 lines. If you don't want to be confused with first commit, second commit, before commit, after commit.... always use git rm --cached [file]
<?php
$file = fopen("members.txt", "r");
$members = array();
while (!feof($file)) {
$members[] = fgets($file);
}
fclose($file);
var_dump($members);
?>
System.out.println(String.format("%-20s= %s" , "label", "content" ));
The output looks like this:
label = content
As a reference I recommend Javadoc on formatter syntax

How do I convert a list of dictionaries to a pandas DataFrame?
The other answers are correct, but not much has been explained in terms of advantages and limitations of these methods. The aim of this post will be to show examples of these methods under different situations, discuss when to use (and when not to use), and suggest alternatives.
DataFrame()
, DataFrame.from_records()
, and .from_dict()
Depending on the structure and format of your data, there are situations where either all three methods work, or some work better than others, or some don't work at all.
Consider a very contrived example.
np.random.seed(0)
data = pd.DataFrame(
np.random.choice(10, (3, 4)), columns=list('ABCD')).to_dict('r')
print(data)
[{'A': 5, 'B': 0, 'C': 3, 'D': 3},
{'A': 7, 'B': 9, 'C': 3, 'D': 5},
{'A': 2, 'B': 4, 'C': 7, 'D': 6}]
This list consists of "records" with every keys present. This is the simplest case you could encounter.
# The following methods all produce the same output.
pd.DataFrame(data)
pd.DataFrame.from_dict(data)
pd.DataFrame.from_records(data)
A B C D
0 5 0 3 3
1 7 9 3 5
2 2 4 7 6
orient='index'
/'columns'
Before continuing, it is important to make the distinction between the different types of dictionary orientations, and support with pandas. There are two primary types: "columns", and "index".
orient='columns'
Dictionaries with the "columns" orientation will have their keys correspond to columns in the equivalent DataFrame.
For example, data
above is in the "columns" orient.
data_c = [
{'A': 5, 'B': 0, 'C': 3, 'D': 3},
{'A': 7, 'B': 9, 'C': 3, 'D': 5},
{'A': 2, 'B': 4, 'C': 7, 'D': 6}]
pd.DataFrame.from_dict(data_c, orient='columns')
A B C D
0 5 0 3 3
1 7 9 3 5
2 2 4 7 6
Note: If you are using pd.DataFrame.from_records
, the orientation is assumed to be "columns" (you cannot specify otherwise), and the dictionaries will be loaded accordingly.
orient='index'
With this orient, keys are assumed to correspond to index values. This kind of data is best suited for pd.DataFrame.from_dict
.
data_i ={
0: {'A': 5, 'B': 0, 'C': 3, 'D': 3},
1: {'A': 7, 'B': 9, 'C': 3, 'D': 5},
2: {'A': 2, 'B': 4, 'C': 7, 'D': 6}}
pd.DataFrame.from_dict(data_i, orient='index')
A B C D
0 5 0 3 3
1 7 9 3 5
2 2 4 7 6
This case is not considered in the OP, but is still useful to know.
If you need a custom index on the resultant DataFrame, you can set it using the index=...
argument.
pd.DataFrame(data, index=['a', 'b', 'c'])
# pd.DataFrame.from_records(data, index=['a', 'b', 'c'])
A B C D
a 5 0 3 3
b 7 9 3 5
c 2 4 7 6
This is not supported by pd.DataFrame.from_dict
.
All methods work out-of-the-box when handling dictionaries with missing keys/column values. For example,
data2 = [
{'A': 5, 'C': 3, 'D': 3},
{'A': 7, 'B': 9, 'F': 5},
{'B': 4, 'C': 7, 'E': 6}]
# The methods below all produce the same output.
pd.DataFrame(data2)
pd.DataFrame.from_dict(data2)
pd.DataFrame.from_records(data2)
A B C D E F
0 5.0 NaN 3.0 3.0 NaN NaN
1 7.0 9.0 NaN NaN NaN 5.0
2 NaN 4.0 7.0 NaN 6.0 NaN
"What if I don't want to read in every single column"? You can easily specify this using the columns=...
parameter.
For example, from the example dictionary of data2
above, if you wanted to read only columns "A', 'D', and 'F', you can do so by passing a list:
pd.DataFrame(data2, columns=['A', 'D', 'F'])
# pd.DataFrame.from_records(data2, columns=['A', 'D', 'F'])
A D F
0 5.0 3.0 NaN
1 7.0 NaN 5.0
2 NaN NaN NaN
This is not supported by pd.DataFrame.from_dict
with the default orient "columns".
pd.DataFrame.from_dict(data2, orient='columns', columns=['A', 'B'])
ValueError: cannot use columns parameter with orient='columns'
Not supported by any of these methods directly. You will have to iterate over your data and perform a reverse delete in-place as you iterate. For example, to extract only the 0th and 2nd rows from data2
above, you can use:
rows_to_select = {0, 2}
for i in reversed(range(len(data2))):
if i not in rows_to_select:
del data2[i]
pd.DataFrame(data2)
# pd.DataFrame.from_dict(data2)
# pd.DataFrame.from_records(data2)
A B C D E
0 5.0 NaN 3 3.0 NaN
1 NaN 4.0 7 NaN 6.0
json_normalize
for Nested DataA strong, robust alternative to the methods outlined above is the json_normalize
function which works with lists of dictionaries (records), and in addition can also handle nested dictionaries.
pd.json_normalize(data)
A B C D
0 5 0 3 3
1 7 9 3 5
2 2 4 7 6
pd.json_normalize(data2)
A B C D E
0 5.0 NaN 3 3.0 NaN
1 NaN 4.0 7 NaN 6.0
Again, keep in mind that the data passed to json_normalize
needs to be in the list-of-dictionaries (records) format.
As mentioned, json_normalize
can also handle nested dictionaries. Here's an example taken from the documentation.
data_nested = [
{'counties': [{'name': 'Dade', 'population': 12345},
{'name': 'Broward', 'population': 40000},
{'name': 'Palm Beach', 'population': 60000}],
'info': {'governor': 'Rick Scott'},
'shortname': 'FL',
'state': 'Florida'},
{'counties': [{'name': 'Summit', 'population': 1234},
{'name': 'Cuyahoga', 'population': 1337}],
'info': {'governor': 'John Kasich'},
'shortname': 'OH',
'state': 'Ohio'}
]
pd.json_normalize(data_nested,
record_path='counties',
meta=['state', 'shortname', ['info', 'governor']])
name population state shortname info.governor
0 Dade 12345 Florida FL Rick Scott
1 Broward 40000 Florida FL Rick Scott
2 Palm Beach 60000 Florida FL Rick Scott
3 Summit 1234 Ohio OH John Kasich
4 Cuyahoga 1337 Ohio OH John Kasich
For more information on the meta
and record_path
arguments, check out the documentation.
Here's a table of all the methods discussed above, along with supported features/functionality.
* Use orient='columns'
and then transpose to get the same effect as orient='index'
.
Just put the labels in a div inside the TD and put the height and overflow.. like below.
<table>
<tr>
<td><div style="height:40px; overflow:hidden">Sample</div></td>
<td><div style="height:40px; overflow:hidden">Text</div></td>
<td><div style="height:40px; overflow:hidden">Here</div></td>
</tr>
</table>
If your experiencing the same problem while querying a DB2 database, you'll need to use the below query.
SELECT *
FROM OPENQUERY(LINK_DB,'SELECT
CITY,
cast(STATE as varchar(40))
FROM DATABASE')
A common issue where the favicon will not show up when expected is cache, if your .htaccess for example reads:
ExpiresByType image/x-icon "access plus 1 month"
Then simply add a random value to your favicon reference:
<link rel="shortcut icon" href="https://example.com/favicon.ico?r=31241" type="image/x-icon" />
Works every time for me even with heavy caching.
You can use a sealed abstract class instead of the enumeration, for example:
sealed abstract class Constraint(val name: String, val verifier: Int => Boolean)
case object NotTooBig extends Constraint("NotTooBig", (_ < 1000))
case object NonZero extends Constraint("NonZero", (_ != 0))
case class NotEquals(x: Int) extends Constraint("NotEquals " + x, (_ != x))
object Main {
def eval(ctrs: Seq[Constraint])(x: Int): Boolean =
(true /: ctrs){ case (accum, ctr) => accum && ctr.verifier(x) }
def main(args: Array[String]) {
val ctrs = NotTooBig :: NotEquals(5) :: Nil
val evaluate = eval(ctrs) _
println(evaluate(3000))
println(evaluate(3))
println(evaluate(5))
}
}
If you use Spring frameworks, then you can use CollectionUtils
to check against both Collections (List, Array) and Map etc.
if(CollectionUtils.isEmpty(...)) {...}
How about access
?
#include <io.h>
if (_access(filename, 0) == -1)
{
// File does not exist
}
Like Vito mentions, this error occurs after Java updates as the path:
C:\ProgramData\Oracle\Java\javapath
is added to the Path
environment variable, causing Eclipse to run using the wrong java version.
To fix the problem:
1) Right-click on Computer
and choose Properties
.
2) Click Advanced system settings
3) Click Environment Variables...
4) Find the Path
variable in the System variables
section.
5) Choose it and click Edit...
6) Find and delete the above mentioned path.
This fixed it for me. I should mention that I already have the path:
c:\Program Files\Java\jdk1.7.0_21\bin
in the Path
variable, but the new path was added to the beginning of the Path
variable and therefore resolution would use that path first.
Here's a jsfiddle with a function call: https://jsfiddle.net/8282emwn/
var marker = new L.Marker([46.947, 7.4448]).on('click', markerOnClick).addTo(map);
function markerOnClick(e)
{
alert("hi. you clicked the marker at " + e.latlng);
}
files <- list.files(pattern = "\\.dbf$")
$
at the end means that this is end of string. "dbf$"
will work too, but adding \\.
(.
is special character in regular expressions so you need to escape it) ensure that you match only files with extension .dbf
(in case you have e.g. .adbf
files).
There is very good example in book Java Concurrency in Practice. Where author (Joshua Bloch) explains how Thread confinement is one of the simplest ways to achieve thread safety and ThreadLocal is more formal means of maintaining thread confinement. In the end he also explain how people can abuse it by using it as global variables.
I have copied the text from the mentioned book but code 3.10 is missing as it is not much important to understand where ThreadLocal should be use.
Thread-local variables are often used to prevent sharing in designs based on mutable Singletons or global variables. For example, a single-threaded application might maintain a global database connection that is initialized at startup to avoid having to pass a Connection to every method. Since JDBC connections may not be thread-safe, a multithreaded application that uses a global connection without additional coordination is not thread-safe either. By using a ThreadLocal to store the JDBC connection, as in ConnectionHolder in Listing 3.10, each thread will have its own connection.
ThreadLocal is widely used in implementing application frameworks. For example, J2EE containers associate a transaction context with an executing thread for the duration of an EJB call. This is easily implemented using a static Thread-Local holding the transaction context: when framework code needs to determine what transaction is currently running, it fetches the transaction context from this ThreadLocal. This is convenient in that it reduces the need to pass execution context information into every method, but couples any code that uses this mechanism to the framework.
It is easy to abuse ThreadLocal by treating its thread confinement property as a license to use global variables or as a means of creating “hidden” method arguments. Like global variables, thread-local variables can detract from reusability and introduce hidden couplings among classes, and should therefore be used with care.
document.getElementById('log').innerHTML += '<br>Some new content!';

In Python 3.8+ you can do
import hashlib
with open("your_filename.png", "rb") as f:
file_hash = hashlib.md5()
while chunk := f.read(8192):
file_hash.update(chunk)
print(file_hash.digest())
print(file_hash.hexdigest()) # to get a printable str instead of bytes
On Python 3.7 and below:
with open("your_filename.png", "rb") as f:
file_hash = hashlib.md5()
chunk = f.read(8192)
while chunk:
file_hash.update(chunk)
chunk = f.read(8192)
print(file_hash.hexdigest())
This reads the file 8192 (or 2¹³) bytes at a time instead of all at once with f.read()
to use less memory.
Consider using hashlib.blake2b
instead of md5
(just replace md5
with blake2b
in the above snippets). It's cryptographically secure and faster than MD5.
tar.gz file is just a tar file that's been gzipped. Both tar and gzip are available for windows.
If you like GUIs (Graphical user interface), 7zip can pack with both tar and gzip.
You simply need to make cab
a string:
cab = '6176'
As the error message states, you cannot do <int> in <string>
:
>>> 1 in '123'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not int
>>>
because integers and strings are two totally different things and Python does not embrace implicit type conversion ("Explicit is better than implicit.").
In fact, Python only allows you to use the in
operator with a right operand of type string if the left operand is also of type string:
>>> '1' in '123' # Works!
True
>>>
>>> [] in '123'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not list

You can use ImportRow
method to copy Row from DataTable to DataTable with the same schema:
var row = SourceTable.Rows[RowNum];
DestinationTable.ImportRow(row);
Update:
With your new Edit, I believe:
var desRow = dataTable.NewRow();
var sourceRow = dataTable.Rows[rowNum];
desRow.ItemArray = sourceRow.ItemArray.Clone() as object[];
will work
This kind of code perhaps should work for You

try:
sys.exit(0)

I found a very nice solution on this site : http://weblogs.sqlteam.com/mladenp/archive/2014/01/10/simple-merging-of-pdf-documents-with-itextsharp-5-4-5.aspx
I update the method in this mode :
public static bool MergePDFs(IEnumerable<string> fileNames, string targetPdf)
{
bool merged = true;
using (FileStream stream = new FileStream(targetPdf, FileMode.Create))
{
Document document = new Document();
PdfCopy pdf = new PdfCopy(document, stream);
PdfReader reader = null;
try
{
document.Open();
foreach (string file in fileNames)
{
reader = new PdfReader(file);
pdf.AddDocument(reader);
reader.Close();
}
}
catch (Exception)
{
merged = false;
if (reader != null)
{
reader.Close();
}
}
finally
{
if (document != null)
{
document.Close();
}
}
}
return merged;
}
Another way using 'awk'
awk NR==$((${RANDOM} % `wc -l < file.name` + 1)) file.name
In my experience the pythonw.exe is faster at least with using pygame.
Just to let you know: I just tried it using a vCard 2.1 file created according to the vCard 2.1 spec. I found that vCard 2.1, despite being an old version, already covered everything I needed, including a base64-encoded photo and international character sets.
It worked perfectly on my unmodified Android 4.1.1 device (Galaxy S3). It also worked on an old iPhone 3GS (iOS 5, via the Evernote app) and a coworker's unmodified old Android 2.1 device. You only need to set the Content-disposition
to attachment
as suggested above.
A minor problem was that I triggered the VCF download using a QR code, which I scanned with the Microsoft Tag app. That app told me Android couldn't handle the text/x-vcard
media type (or just text/vcard
, no matter). Once I opened the link in a Web browser (I tried Chrome and the Android default browser), it worked fine.
There is no way.
This question is basically a duplicate of Is there a way to hide the new HTML5 spinbox controls shown in Google Chrome & Opera? but maybe not a full duplicate, since the motivation is given.
If the purpose is “browser's awareness of the content being purely numeric”, then you need to consider what that would really mean. The arrows, or spinners, are part of making numeric input more comfortable in some cases. Another part is checking that the content is a valid number, and on browsers that support HTML5 input enhancements, you might be able to do that using the pattern
attribute. That attribute may also affect a third input feature, namely the type of virtual keyboard that may appear.
For example, if the input should be exactly five digits (like postal numbers might be, in some countries), then <input type="text" pattern="[0-9]{5}">
could be adequate. It is of course implementation-dependent how it will be handled.
To inject an Object, its class must be known to the CDI mechanism. Usualy adding the @Named annotation will do the trick.
Thanks to MantisD's post, for Bootstrap 4 this worked nicely.

Those are all ways to start the standard minecraft launcher with those credentials in the text boxes.
There used to be a way to login to minecraft without the launcher using the command line, but it has since been patched.
If you want to make a custom launcher using the command line then good luck, the only way to login to the minecraft jar(IE: the way the launcher does it) is to send a post request to https://login.minecraft.net/ with the username,password,launcher version, and a RSA key. It then parses the pseudo Json, and uses the session token from that to authenticate the jar from the command line with a load of arguments.
If you are trying to make a minecraft launcher and you have no knowledge of java,http requests or json then you have no chance.
Swift
You can use laravel MessageBag to add our own messages to existing messages.
To use MessageBag you need to use:
use Illuminate\Support\MessageBag;
In the controller:
MessageBag $message_bag
$message_bag->add('message', trans('auth.confirmation-success'));
return redirect('login')->withSuccess($message_bag);
Hope it will help some one.

Cleanest version specially good if you just want to get the .value

Additional to the above - the QEMU website has good documentation about setting up an ARM based emulator: http://qemu.weilnetz.de/qemu-doc.html#ARM-System-emulator
str.join()
works fine in Python 3, you just need to get the order of the arguments correct
>>> str.join('.', ('a', 'b', 'c'))
'a.b.c'
Although System.Collections.Generic.Dictionary matches the tag "hashmap" and will work well in your example, it is not an exact equivalent of C++'s std::map - std::map is an ordered collection.
If ordering is important you should use SortedDictionary.
My async function
const getAllRedis = async (key) => {
let obj = [];
await client.hgetall(key, (err, object) => {

string stringtodate = ((DateTime)row.Cells[4].Value).ToString("MM-dd-yyyy");
textBox9.Text = stringtodate;
Another way to address this annoyance is to create your own CSS class that does not set the !important at the end of rule, like this:
.hideMe {
display: none;
}
and used like so :
<div id="header-mask" class="hideMe"></div>
and now jQuery hiding works
$('#header-mask').show();
In Chrome you can use copy('the text or variable etc')
. While this isn't cross-browser (and doesn't work in a snippet?), you could add it to the other cross-browser answers.
Alternatively, try removing "data" and making the URL "logtime.php?userID="+userId
I like Brian's answer better, this answer is just because you're trying to use URL parameter syntax in "data" and I wanted to demonstrate where you can use that syntax correctly.
Tried all above. Didn't work.
Here's what worked. Go to the file called modules.xml
Delete all the modules there. Clean and rebuild.
I think any style that breaks a language's own style guidelines (without due reason) is ugly and therefore "bad".
No doubt the code you've seen was written by someone who used to work on a language where underscores were acceptable.
Some people just cannot adapt to new coding styles...
This solution with few code. I think is better.
<?php echo wp_get_attachment_image( get_term_meta( get_queried_object_id(), 'thumbnail_id', 1 ), 'thumbnail' ); ?>
You're missing comma (,
) inbetween:
>>> ((1,2) (2,3))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'tuple' object is not callable
Put comma:
>>> ((1,2), (2,3))
((1, 2), (2, 3))
bit
will be the simplest and also takes up the least space. Not very verbose compared to "Y/N" but I am fine with it.
You can use jquery-rss or Vanilla RSS, which comes with nice templating and is super easy to use:
// Example for jquery.rss
$("#your-div").rss("https://stackoverflow.com/feeds/question/10943544", {
limit: 3,
layoutTemplate: '<ul class="inline">{entries}</ul>',
entryTemplate: '<li><a href="{url}">[{author}@{date}] {title}</a><br/>{shortBodyPlain}</li>'
})
// Example for Vanilla RSS
const RSS = require('vanilla-rss');
const rss = new RSS(
document.querySelector("#your-div"),
"https://stackoverflow.com/feeds/question/10943544",
{
// options go here
}
);
rss.render().then(() => {
console.log('Everything is loaded and rendered');
});
See http://jsfiddle.net/sdepold/ozq2dn9e/1/ for a working example.

If you happen to be using date in a MacOS environment, try this:
ST1:~ ejf$ date
Mon Feb 20 21:55:48 CST 2017
ST1:~ ejf$ date -v-1m +%m
01
ST1:~ ejf$ date -v+1m +%m
03
Also, I'd rather calculate the previous and next month on the first day of each month, this way you won't have issues with months ending the 30/31 or 28/29 (Feb/Feb leap year)
I will describe what I use:
Validation: string contains more than 5 digits.
Cleaning: removing all non digits symbols, write in db only numbers. I'm lucky, because in my country (Russia) everybody has phone numbers with 10 digits. So I store in db only 10 diits. If you are writing multi-country application, then you should make a comprehensive validation.
Rendering: I write custom template tag to render it in template nicely. Or even render it like a picture - it is more safe to prevent sms spam.
You can make a view with a different dtype, and then copy in-place into the view:
import numpy as np
x = np.arange(10, dtype='int32')
y = x.view('float32')
y[:] = x
print(y)
yields
array([ 0., 1., 2., 3., 4., 5., 6., 7., 8., 9.], dtype=float32)
To show the conversion was in-place, note that copying from x
to y
altered x
:
print(x)
prints
array([ 0, 1065353216, 1073741824, 1077936128, 1082130432,
1084227584, 1086324736, 1088421888, 1090519040, 1091567616])
Difference between app.use
& app.get
:
app.use
? It is generally used for introducing middlewares in your application and can handle all type of HTTP requests.
app.get
? It is only for handling GET HTTP requests.
Now, there is a confusion between app.use
& app.all
. No doubt, there is one thing common in them, that both can handle all kind of HTTP requests.
But there are some differences which recommend us to use app.use for middlewares and app.all for route handling.
app.use()
? It takes only one callback.
app.all()
? It can take multiple callbacks.
app.use()
will only see whether url starts with specified path.
But, app.all()
will match the complete path.
For example,
app.use( "/book" , middleware);
// will match /book
// will match /book/author
// will match /book/subject
app.all( "/book" , handler);
// will match /book
// won't match /book/author
// won't match /book/subject
app.all( "/book/*" , handler);
// won't match /book
// will match /book/author
// will match /book/subject
next()
call inside the app.use()
will call either the next middleware or any route handler, but next()
call inside app.all()
will invoke the next route handler (app.all()
, app.get/post/put...
etc.) only. If there is any middleware after, it will be skipped. So, it is advisable to put all the middlewares always above the route handlers.I see that we have (beside others) basically two options:
a.sort_by { |h| -h[:bar] }
and
a.sort_by { |h| h[:bar] }.reverse
While both ways give you the same result when your sorting key is unique, keep in mind that the reverse
way will reverse the order of keys that are equal.
Example:
a = [{foo: 1, bar: 1},{foo: 2,bar: 1}]
a.sort_by {|h| -h[:bar]}
=> [{:foo=>1, :bar=>1}, {:foo=>2, :bar=>1}]
a.sort_by {|h| h[:bar]}.reverse
=> [{:foo=>2, :bar=>1}, {:foo=>1, :bar=>1}]
While you often don't need to care about this, sometimes you do. To avoid such behavior you could introduce a second sorting key (that for sure needs to be unique at least for all items that have the same sorting key):
a.sort_by {|h| [-h[:bar],-h[:foo]]}
=> [{:foo=>2, :bar=>1}, {:foo=>1, :bar=>1}]
a.sort_by {|h| [h[:bar],h[:foo]]}.reverse
=> [{:foo=>2, :bar=>1}, {:foo=>1, :bar=>1}]

For forms, use the [FromForm]
attribute instead of the [FromBody]
attribute.
The below controller works with ASP.NET Core 1.1:
public class MyController : Controller
{
[HttpPost]
public async Task<IActionResult> Submit([FromForm] MyModel model)
{
//...
}
}
Note: [FromXxx]
is required if your controller is annotated with [ApiController]
. For normal view controllers it can be omitted.

In case of float values with characters 'e' '+' it errors out if we try to convert in decimal. ('2.81104e+006'). It still pass ISNUMERIC test.
SELECT ISNUMERIC('2.81104e+006')
returns 1
.
SELECT convert(decimal(15,2), '2.81104e+006')
returns

And
SELECT try_convert(decimal(15,2), '2.81104e+006')

SELECT convert(float, '2.81104e+006')
returns the correct value 2811040

In C++17, new functions std::to_chars and std::from_chars are introduced in header charconv.
std::to_chars is locale-independent, non-allocating, and non-throwing.
Only a small subset of formatting policies used by other libraries (such as std::sprintf) is provided.
From std::to_chars, same for std::from_chars.
The guarantee that std::from_chars can recover every floating-point value formatted by to_chars exactly is only provided if both functions are from the same implementation
// See en.cppreference.com for more information, including format control.

Although it's not fully implemented by compilers, it definitely will be implemented.
Here's a LINQ solution which is virtually the same but more scalable:
new[] { "a", "b", "c" }.Any(c => s.Contains(c))
The DisplayFormat attribute did not work for me in either form upon initial load. I created an EditorTemplate instead:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.DateTime>" %>

<%=
Html.TextBox("", Model.ToShortDateString(), new { @class = "date-range" }) %>
In ubuntu it should be under

where user_name is logged in user name and product_name could be e.g. .AndroidStudio1.5
Slightly different from what you described, but I think this might be what you actually need:
svn blame filename
It will print the file with each line prefixed by the time and author of the commit that last changed it.
In Symfony you can use this for protocol and host:
{{ app.request.schemeAndHttpHost }}
Though @alessandro1997 gave a perfect answer about concatenation.
Since Facebook's Android SDK v4.0 you need to execute the following:
LoginManager.getInstance().logOut();
This is not sufficient. This will simply clear cached access token and profile so that AccessToken.getCurrentAccessToken()
and Profile.getCurrentProfile()
will now become null.
To completely logout you need to revoke permissions and then call LoginManager.getInstance().logOut();
. To revoke permission execute following graph API -
GraphRequest delPermRequest = new GraphRequest(AccessToken.getCurrentAccessToken(), "/{user-id}/permissions/", null, HttpMethod.DELETE, new GraphRequest.Callback() {
@Override
public void onCompleted(GraphResponse graphResponse) {
if(graphResponse!=null){
FacebookRequestError error =graphResponse.getError();
if(error!=null){
Log.e(TAG, error.toString());
}else {
finish();
}
}
}
});
Log.d(TAG,"Executing revoke permissions with graph path" + delPermRequest.getGraphPath());
delPermRequest.executeAsync();
All the code is client side, I hope you fine this helpful:
First thing there are 3 functions we will use:
function setCookie(c_name, value, exdays) {
var exdate = new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value = escape(value) + ((exdays == null) ? "" : "; expires=" + exdate.toUTCString());
document.cookie = c_name + "=" + c_value;
}
function getCookie(c_name) {
var i, x, y, ARRcookies = document.cookie.split(";");
for (i = 0; i < ARRcookies.length; i++) {
x = ARRcookies[i].substr(0, ARRcookies[i].indexOf("="));
y = ARRcookies[i].substr(ARRcookies[i].indexOf("=") + 1);
x = x.replace(/^\s+|\s+$/g, "");
if (x == c_name) {
return unescape(y);
}
}
}
function DeleteCookie(name) {
document.cookie = name + '=; expires=Thu, 01-Jan-70 00:00:01 GMT;';
}
Now we will start with the page load:
$(window).load(function () {
//if IsRefresh cookie exists
var IsRefresh = getCookie("IsRefresh");
if (IsRefresh != null && IsRefresh != "") {
//cookie exists then you refreshed this page(F5, reload button or right click and reload)
//SOME CODE
DeleteCookie("IsRefresh");
}
else {
//cookie doesnt exists then you landed on this page
//SOME CODE
setCookie("IsRefresh", "true", 1);
}
})
start all daemons and run the command as "hadoop namenode -recover -force" stop the daemons and start again.. wait some time to recover data.
Here's how I solved that problem:
int pHeight = picture.getHeight();
int pWidth = picture.getWidth();
int vWidth = preview.getWidth();
preview.getLayoutParams().height = (int)(vWidth*((double)pHeight/pWidth));
preview - imageView with width setted to "match_parent" and scaleType to "cropCenter"
picture - Bitmap object to set in imageView src.
That's works pretty well for me.

Use ast.literal_eval

Why is flag always converting to True?
Non-empty strings are always True in Python.

If NumPy is an option, then:
>>> import StringIO
>>> import numpy as np
>>> s = 'True - False - True'
>>> c = StringIO.StringIO(s)
>>> np.genfromtxt(c, delimiter='-', autostrip=True, dtype=None) #or dtype=bool
array([ True, False, True], dtype=bool)
Don't forget to take into consideration the global flag in your regexp :
var reg = /abc/g;
!!'abcdefghi'.match(reg); // => true
!!'abcdefghi'.match(reg); // => true
reg.test('abcdefghi'); // => true
reg.test('abcdefghi'); // => false <=
This is because Regexp keeps track of the lastIndex when a new match is found.
This is a a recompilation of my 3 favorite answers on this board:
The results are an easy to use, and easily configurable function.
First argument can be a select object, the ID of a select object, or an array with at least 2 dimensions.
Second argument is optional. Defaults to sorting by option text, index 0. Can be passed any other index so sort on that. Can be passed 1, or the text "value", to sort by value.
sortSelect('select_object_id');
sortSelect('select_object_id', 0);
sortSelect(selectObject);
sortSelect(selectObject, 0);
sortSelect('select_object_id', 'value');
sortSelect('select_object_id', 1);
sortSelect(selectObject, 1);
var myArray = [
['ignored0', 'ignored1', 'Z-sortme2'],
['ignored0', 'ignored1', 'A-sortme2'],
['ignored0', 'ignored1', 'C-sortme2'],
];
sortSelect(myArray,2);
This last one will sort the array by index-2, the sortme's.
function sortSelect(selElem, sortVal) {
// Checks for an object or string. Uses string as ID.
switch(typeof selElem) {
case "string":
selElem = document.getElementById(selElem);
break;
case "object":
if(selElem==null) return false;
break;
default:
return false;
}
// Builds the options list.
var tmpAry = new Array();
for (var i=0;i<selElem.options.length;i++) {
tmpAry[i] = new Array();
tmpAry[i][0] = selElem.options[i].text;
tmpAry[i][1] = selElem.options[i].value;
}
// allows sortVal to be optional, defaults to text.
switch(sortVal) {
case "value": // sort by value
sortVal = 1;
break;
default: // sort by text
sortVal = 0;
}
tmpAry.sort(function(a, b) {
return a[sortVal] == b[sortVal] ? 0 : a[sortVal] < b[sortVal] ? -1 : 1;
});
// removes all options from the select.
while (selElem.options.length > 0) {
selElem.options[0] = null;
}
// recreates all options with the new order.
for (var i=0;i<tmpAry.length;i++) {
var op = new Option(tmpAry[i][0], tmpAry[i][1]);
selElem.options[i] = op;
}
return true;
}
The OP needed to cast as string outside the {% set ... %}
.
But if that not your case you can do:
{% set curYear = 2013 | string() %}
Note that you need the parenthesis on that jinja filter.
If you're concatenating 2 variables, you can also use the ~
custom operator.
Sub Button167_Click()
If ThisWorkbook.Worksheets(1).Shapes("Check Box 1").OLEFormat.Object.Value = 1 Then
Range("Y12").Value = 1
Else
Range("Y12").Value = 0
End If
End Sub
1 is checked, -4146 is unchecked, 2 is mixed (grey box)
You can use Line height a big as height of the div.
But for me best solution is this --> position:relative; top:50%; transform:translate(0,50%);
Regardless of your environment (gcloud or not ) , you need to point your kubectl to kubeconfig. By default, kubectl expects the path as $HOME/.kube/config or point your custom path as env variable (for scripting etc ) export KUBECONFIG=/your_kubeconfig_path
Please refer :: https://kubernetes.io/docs/concepts/configuration/organize-cluster-access-kubeconfig/
If you don't have a kubeconfig file for your cluster, create one by referring :: https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters/
It is required to find cluster's ca.crt , apiserver-kubelet-client key and cert.
Although your answer has many solutions I think this is a great way to save lines of code. Try using spans which is great for situations like yours.
span.bold(This name can be anything do not include parenthesis) { font-weight: bold; }

driver.Navigate().GoToUrl("http://www.example.com/");
driver.GetScreenshot().SaveAsFile("screenshot.png", ImageFormat.Png);
driver.Quit();

IE doesn't allow this anymore (since Version 10, I believe) and will ignore such scripts. FF and Chrome still tolerate them, but there are chances that some day they will drop this as non-standard.
Edit: 2020-05-08: Is seems the website I quoted is no longer controlled by the person who wrote the advice, so I'm removing the link to the site. Thanks for letting me know baxx.
If someone's still struggling a bit after the great answers already provided, I found advice on a website that no longer is available.
Essential quote from the site I mentioned:
"The same can be specified programmatically in this way:
import sys
sys.path.append('..')
Of course the code above must be written before the other import statement.
It's pretty obvious that it has to be this way, thinking on it after the fact. I was trying to use the sys.path.append('..') in my tests, but ran into the issue posted by OP. By adding the import and sys.path defintion before my other imports, I was able to solve the problem.
As far as I know, transitions currently work in Safari, Chrome, Firefox, Opera and Internet Explorer 10+.
This should produce a fade effect for you in these browsers:
a {_x000D_
background-color: #FF0;_x000D_
}_x000D_
_x000D_
a:hover {_x000D_
background-color: #AD310B;_x000D_
-webkit-transition: background-color 1000ms linear;_x000D_
-ms-transition: background-color 1000ms linear;_x000D_
transition: background-color 1000ms linear;_x000D_
}
_x000D_
<a>Navigation Link</a>
_x000D_
Note: As pointed out by Gerald in the comments, if you put the transition on the a
, instead of on a:hover
it will fade back to the original color when your mouse moves away from the link.
This might come in handy, too: CSS Fundamentals: CSS 3 Transitions
For a project that's using the CLI, you will usually use ng serve. In other cases you may want to use npm start. Here the detailed explanation:
Will serve a project that is 'Angular CLI aware', i.e. a project that has been created using the Angular CLI, particularly using:
ng new app-name
So, if you've scaffolded a project using the CLI, you'll probably want to use ng serve
This can be used in the case of a project that is not Angular CLI aware (or it can simply be used to run 'ng serve' for a project that's Angular CLI aware)
As the other answers state, this is an npm command that will run the npm command(s) from the package.json that have the identifier 'start', and it doesn't just have to run 'ng serve'. It's possible to have something like the following in the package.json:
"scripts": {
"build:watch": "tsc -p src/ -w",
"serve": "lite-server -c=bs-config.json",
"start": "concurrently \"npm run build:watch\" \"npm run serve\""
...
},
"devDependencies": {
"concurrently": "^3.2.0",
"lite-server": "^2.2.2",
In this case, 'npm start' will result in the following commands to be run:
concurrently "npm run build:watch" "npm run serve"
This will concurrently run the TypeScript compiler (watching for code changes), and run the Node lite-server (which users BrowserSync)
Using Javascript
var elemDiv = document.createElement('div');
elemDiv.style.cssText = 'position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000;';
document.body.appendChild(elemDiv);
Using jQuery
$('body').append('<div style="position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000;"></div>');
In my case it was
username : root
password : mysql

net stop <your service> && net start <your service>
No net restart

Keypress event is deprecated, You should use Keydown event instead.
https://developer.mozilla.org/en-US/docs/Web/API/Document/keypress_event
handleKeyDown(event) {
if(event.keyCode === 13) {
console.log('Enter key pressed')
}
}
render() {
return <input type="text" onKeyDown={this.handleKeyDown} />
}
Here is an updated solution for Java8, using lambdas and streams:
System.out.println(list.stream()
.map(Object::toString)
.collect(Collectors.joining("\n")));
Or, without joining the list into one large string:
list.stream().forEach(System.out::println);
How about this :
@client = TinyTds::Client.new(
:adapter => 'mysql2',
:host => 'host',
:database => 'siteconfig_development',
:username => 'username',
:password => 'password'
sql = "SELECT * FROM users"
result = @client.execute(sql)
results.each do |row|
puts row[0]
end
You need to have TinyTds gem installed, since you didn't specify it in your question I didn't use Active Record
Python has a built-in datatype for an unordered collection of (hashable) things, called a set
. If you convert both lists to sets, the comparison will be unordered.
set(x) == set(y)
EDIT: @mdwhatcott points out that you want to check for duplicates. set
ignores these, so you need a similar data structure that also keeps track of the number of items in each list. This is called a multiset; the best approximation in the standard library is a collections.Counter
:
>>> import collections
>>> compare = lambda x, y: collections.Counter(x) == collections.Counter(y)
>>>
>>> compare([1,2,3], [1,2,3,3])
False
>>> compare([1,2,3], [1,2,3])
True
>>> compare([1,2,3,3], [1,2,2,3])
False

Good Luck.
To solve your other problem, where you need to set scrolled
if the user scrolls manually, you'd have to attach a handler to the window scroll event. Generally this is a bad idea as the handler will fire a lot, a common technique is to set a timeout, like so:
var timer = 0;
$(window).scroll(function() {
if (timer) {
clearTimeout(timer);
}
timer = setTimeout(function() {
scrolled = $(window).scrollTop();
}, 250);
});
Well, why do you have %20
url-quoting escapes in a formatting string in first place? Ideally you'd do the interpolation formatting first:
formatting_template = 'Hello World%s'
text = '!'
full_string = formatting_template % text
Then you url quote it afterwards:
result = urllib.quote(full_string)
That is better because it would quote all url-quotable things in your string, including stuff that is in the text
part.
I honestly thought that the casting method would work fine. Since it doesn't you can try stringstream. An example is below:
#include <sstream>
#include <string>
std::stringstream ss;
std::string target;
char mychar = 'a';
ss << mychar;
ss >> target;
Simple way is to convert into column
SELECT COLUMN_VALUE FROM TABLE (SPLIT ('19869,19572,19223,18898,10155,'))
CREATE TYPE split_tbl as TABLE OF VARCHAR2(32767);
CREATE OR REPLACE FUNCTION split (p_list VARCHAR2, p_del VARCHAR2 := ',')
RETURN split_tbl
PIPELINED IS
l_idx PLS_INTEGER;
l_list VARCHAR2 (32767) := p_list;
l_value VARCHAR2 (32767);
BEGIN
LOOP
l_idx := INSTR (l_list, p_del);
IF l_idx > 0 THEN
PIPE ROW (SUBSTR (l_list, 1, l_idx - 1));
l_list := SUBSTR (l_list, l_idx + LENGTH (p_del));
ELSE
PIPE ROW (l_list);
EXIT;
END IF;
END LOOP;
RETURN;
END split;
You are probably having a problem with the sort of CSV file that you have.
Open the CSV file with a text editor, check that all the separations are done with the comma, and not semicolon and try the script again. It should work fine.
I would like to add a data.table
variant using the rank()
function which provides the additional possibility to change the ordering and thus makes it a bit more flexible than the seq_len()
solution and is pretty similar to row_number functions in RDBMS.
# Variant with ascending ordering
library(data.table)
dt <- data.table(df)
dt[, .( val
, num = rank(val))
, by = list(cat)][order(cat, num),]
cat val num
1: aaa 0.05638315 1
2: aaa 0.25767250 2
3: aaa 0.30776611 3
4: aaa 0.46854928 4
5: aaa 0.55232243 5
6: bbb 0.17026205 1

I'm new to python too. Here is something that looks like will do what you want to
axes([0.08, 0.08, 0.94-0.08, 0.94-0.08]) #[left, bottom, width, height]
axis('scaled')`
I believe this decides the size of the canvas.
Let's try this way:
select
a.ip,
a.os,
a.hostname,
a.port,
a.protocol,
b.state
from a
left join b
on a.ip = b.ip
and a.port = b.port /*if you has to filter by columns from right table , then add this condition in ON clause*/
where a.somecolumn = somevalue /*if you have to filter by some column from left table, then add it to where condition*/
So, in where
clause you can filter result set by column from right table only on this way:
...
where b.somecolumn <> (=) null
The easiest way to do this is to format a cell the way you want it, then use the "cell format ..." contextual menu to get to the fill and format colours, use the "more colors ..." button to get to the hexagon colour selector, select the custom tab.
The RGB colours are as in the table at the bottom of the pane. If you prefer HSL values change the color model from RGB to HSL. I have used this to change the saturation on my bad cells. A higher luminosity gives a worse results and the shade of all the cells is the same just the deepness of the colour is modified.
value = value.setScale(2, RoundingMode.CEILING)
This can be done even without renaming the local branch in three simple steps:
In a POST method, you can put an array. However, in a PUT method, you should use http_build_query
to build the params like this:
curl_setopt( $ch, CURLOPT_POSTFIELDS, http_build_query( $postArr ) );
You could use an onclick
event handler in order to get the input value for the text field. Make sure you give the field an unique id
attribute so you can refer to it safely through document.getElementById()
:
If you want to dynamically add elements, you should have a container where to place them. For instance, a <div id="container">
. Create new elements by means of document.createElement()
, and use appendChild()
to append each of them to the container. You might be interested in outputting a meaningful name
attribute (e.g. name="member"+i
for each of the dynamically generated <input>
s if they are to be submitted in a form.
Notice you could also create <br/>
elements with document.createElement('br')
. If you want to just output some text, you can use document.createTextNode()
instead.
Also, if you want to clear the container every time it is about to be populated, you could use hasChildNodes()
and removeChild()
together.
<html>
<head>
<script type='text/javascript'>
function addFields(){
// Number of inputs to create
var number = document.getElementById("member").value;
// Container <div> where dynamic content will be placed
var container = document.getElementById("container");
// Clear previous contents of the container
while (container.hasChildNodes()) {
container.removeChild(container.lastChild);
}
for (i=0;i<number;i++){
// Append a node with a random text
container.appendChild(document.createTextNode("Member " + (i+1)));
// Create an <input> element, set its type and name attributes
var input = document.createElement("input");
input.type = "text";
input.name = "member" + i;
container.appendChild(input);
// Append a line break
container.appendChild(document.createElement("br"));
}
}
</script>
</head>
<body>
<input type="text" id="member" name="member" value="">Number of members: (max. 10)<br />
<a href="#" id="filldetails" onclick="addFields()">Fill Details</a>
<div id="container"/>
</body>
</html>

In many cases, particularly with text classification it is not enough just to store the classifier but you'll need to store the vectorizer as well so that you can vectorize your input in future.

pickle.dump((vectorizer, clf), fout)
future use case:
with open('model.pkl', 'rb') as fin:
vectorizer, clf = pickle.load(fin)
X_new = vectorizer.transform(new_samples)
X_new_preds = clf.predict(X_new)
Before dumping the vectorizer, one can delete the stop_words_ property of vectorizer by:
vectorizer.stop_words_ = None
to make dumping more efficient. Also if your classifier parameters is sparse (as in most text classification examples) you can convert the parameters from dense to sparse which will make a huge difference in terms of memory consumption, loading and dumping. Sparsify the model by:
clf.sparsify()
Which will automatically work for SGDClassifier but in case you know your model is sparse (lots of zeros in clf.coef_) then you can manually convert clf.coef_ into a csr scipy sparse matrix by:
clf.coef_ = scipy.sparse.csr_matrix(clf.coef_)
and then you can store it more efficiently.

You can do like
HTML in PHP :
<?php
echo "<table>";
echo "<tr>";
echo "<td>Name</td>";
echo "<td>".$name."</td>";
echo "</tr>";
echo "</table>";
?>
Or You can write like.
PHP in HTML :
<?php /*Do some PHP calculation or something*/ ?>
<table>
<tr>
<td>Name</td>
<td><?php echo $name;?></td>
</tr>
</table>
<?php /*Do some PHP calculation or something*/ ?>
Means:
You can open a PHP tag with <?php
, now add your PHP code, then close the tag with ?>
and then write your html code. When needed to add more PHP, just open another PHP tag with <?php
.
It is impossible to safely escape a string without a DB connection. mysql_real_escape_string()
and prepared statements need a connection to the database so that they can escape the string using the appropriate character set - otherwise SQL injection attacks are still possible using multi-byte characters.
If you are only testing, then you may as well use mysql_escape_string()
, it's not 100% guaranteed against SQL injection attacks, but it's impossible to build anything safer without a DB connection.
je : Jump if equal:
399 3fb: 64 48 33 0c 25 28 00 xor %fs:0x28,%rcx
400 402: 00 00
401 404: 74 05 je 40b <sims_get_counter+0x51>
Here you go:
InputStream is = new ByteArrayInputStream( myString.getBytes() );
Update For multi-byte support use (thanks to Aaron Waibel's comment):
InputStream is = new ByteArrayInputStream(Charset.forName("UTF-16").encode(myString).array());
Please see ByteArrayInputStream manual.
It is safe to use a charset argument in String#getBytes(charset) method above.
After JDK 7+ you can use
java.nio.charset.StandardCharsets.UTF_16
instead of hardcoded encoding string:
InputStream is = new ByteArrayInputStream(StandardCharsets.UTF_16.encode(myString).array());
I've observed this with STS and Eclipse and running java from CMD too on Windows 7/8/10 and following was my simple solution:
Actually, when I installed JDK 8 and STS/Eclipse it created one directory i.e. C:\ProgramData\Oracle\Java\javapath
with the following files:
Along with that, it appended Path Environment variable of System with this location C:\ProgramData\Oracle\Java\javapath
I've just removed above entry from Path Environment variable of System and added the location of the actual JDK instead i.e. C:\Program Files\Java\jdk1.8.0_131\bin
Now that is not necessary to add that -vm option in eclipse.ini or SpringToolSuite4.ini either.
It’s a name for the ::
operator in PHP. It literally means "double colon". For some reason they named it in Hebrew. Check your code syntax, and put a ::
where appropriate :-)
LocalDate.parse(
"23/01/2017" ,
DateTimeFormatter.ofPattern( "dd/MM/uuuu" , Locale.UK )
).format(
DateTimeFormatter.ofPattern( "uuuu/MM/dd" , Locale.UK )
)
2017/01/23
The answer by Christopher Parker is correct but outdated. The troublesome old date-time classes such as java.util.Date
, java.util.Calendar
, and java.text.SimpleTextFormat
are now legacy, supplanted by the java.time classes.
Parse the input string as a date-time object, then generate a new String object in the desired format.
The LocalDate
class represents a date-only value without time-of-day and without time zone.
DateTimeFormatter fIn = DateTimeFormatter.ofPattern( "dd/MM/uuuu" , Locale.UK ); // As a habit, specify the desired/expected locale, though in this case the locale is irrelevant.
LocalDate ld = LocalDate.parse( "23/01/2017" , fIn );
Define another formatter for the output.
DateTimeFormatter fOut = DateTimeFormatter.ofPattern( "uuuu/MM/dd" , Locale.UK );
String output = ld.format( fOut );
2017/01/23
By the way, consider using standard ISO 8601 formats for strings representing date-time values.
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
UPDATE: The Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes. This section here is left for the sake of history.
For fun, here is his code adapted for using the Joda-Time library.
// © 2013 Basil Bourque. This source code may be used freely forever by anyone taking full responsibility for doing so.
// import org.joda.time.*;
// import org.joda.time.format.*;
final String OLD_FORMAT = "dd/MM/yyyy";
final String NEW_FORMAT = "yyyy/MM/dd";
// August 12, 2010
String oldDateString = "12/08/2010";
String newDateString;
DateTimeFormatter formatterOld = DateTimeFormat.forPattern(OLD_FORMAT);
DateTimeFormatter formatterNew = DateTimeFormat.forPattern(NEW_FORMAT);
LocalDate localDate = formatterOld.parseLocalDate( oldDateString );
newDateString = formatterNew.print( localDate );
Dump to console…
System.out.println( "localDate: " + localDate );
System.out.println( "newDateString: " + newDateString );
When run…
localDate: 2010-08-12
newDateString: 2010/08/12
Html.Raw()
returns IHtmlString
, not the ordinary string
. So, you cannot write them in opposite sides of :
operator. Remove that .ToString()
calling
@{int count = 0;}
@foreach (var item in Model.Resources)
{
@(count <= 3 ? Html.Raw("<div class=\"resource-row\">"): Html.Raw(""))
// some code
@(count <= 3 ? Html.Raw("</div>") : Html.Raw(""))
@(count++)
}
By the way, returning IHtmlString
is the way MVC recognizes html content and does not encode it. Even if it hasn't caused compiler errors, calling ToString()
would destroy meaning of Html.Raw()
Correct me if I'm wrong, but this seems like the simplest way (for one argument, anyway):
function myFunction(Required,Optional)
{
if (arguments.length<2) Optional = "Default";
//Your code
}
If any one had the same problem as me and the charset was already correct, simply do this:
Going on the assumption you're using TNSNAMES naming, here's a couple of things to do:
> SERVICENAME_alias = > (DESCRIPTION = > (ADDRESS = (PROTOCOL = TCP)(HOST = HOST.XYZi.com)(PORT = 1521)) > (CONNECT_DATA = (SERVICE_NAME = SERVICENAME))
This is assuming you're using the standard Oracle port of 1521. Note that servicename_alias can be any name you want to use on the local system. You may also find that you need to specify (SID = SERVICENAME) instead of (SERVICENAME=SERVICENAME).
Just a minor addition: The speed difference between memcpy()
and std::copy()
can vary quite a bit depending on if optimizations are enabled or disabled. With g++ 6.2.0 and without optimizations memcpy()
clearly wins:
Benchmark Time CPU Iterations
---------------------------------------------------
bm_memcpy 17 ns 17 ns 40867738
bm_stdcopy 62 ns 62 ns 11176219
bm_stdcopy_n 72 ns 72 ns 9481749
When optimizations are enabled (-O3
), everything looks pretty much the same again:
Benchmark Time CPU Iterations
---------------------------------------------------
bm_memcpy 3 ns 3 ns 274527617
bm_stdcopy 3 ns 3 ns 272663990
bm_stdcopy_n 3 ns 3 ns 274732792
The bigger the array the less noticeable the effect gets, but even at N=1000
memcpy()
is about twice as fast when optimizations aren't enabled.
Source code (requires Google Benchmark):
#include <string.h>
#include <algorithm>
#include <vector>
#include <benchmark/benchmark.h>
constexpr int N = 10;
void bm_memcpy(benchmark::State& state)
{
std::vector<int> a(N);
std::vector<int> r(N);
while (state.KeepRunning())
{
memcpy(r.data(), a.data(), N * sizeof(int));
}
}
void bm_stdcopy(benchmark::State& state)
{
std::vector<int> a(N);
std::vector<int> r(N);
while (state.KeepRunning())
{
std::copy(a.begin(), a.end(), r.begin());
}
}
void bm_stdcopy_n(benchmark::State& state)
{
std::vector<int> a(N);
std::vector<int> r(N);
while (state.KeepRunning())
{
std::copy_n(a.begin(), N, r.begin());
}
}

For arbitrary SQL, use jOOQ. jOOQ currently supports SELECT
, INSERT
, UPDATE
, DELETE
, TRUNCATE
, and MERGE
. You can create SQL like this:
String sql1 = DSL.using(SQLDialect.MYSQL)
.select(A, B, C)
.from(MY_TABLE)
.where(A.equal(5))
.and(B.greaterThan(8))
.getSQL();
String sql2 = DSL.using(SQLDialect.MYSQL)
.insertInto(MY_TABLE)
.values(A, 1)
.values(B, 2)
.getSQL();
String sql3 = DSL.using(SQLDialect.MYSQL)
.update(MY_TABLE)
.set(A, 1)
.set(B, 2)
.where(C.greaterThan(5))
.getSQL();
Instead of obtaining the SQL string, you could also just execute it, using jOOQ. See
(Disclaimer: I work for the company behind jOOQ)
git remote set-url --push origin
should work, as you mentioned, but you need to explicitly provide the url instead of an alternative remote name, e.g.
git remote set-url --push origin [email protected]:contributor/repo.git
You can confirm whether this worked by doing a git remote -v
. E.g.
? ~/go/src/github.com/stretchr/testify/ master git remote -v
fork [email protected]:contributor/testify.git (fetch)
fork [email protected]:contributor/testify.git (push)
origin [email protected]:stretchr/testify (fetch)
origin [email protected]:contributor/testify.git (push)
Just an update.
Now if it's a github repository then using just a github shorthand is enough if you do not mind the version of course.
$ bower install desandro/masonry
You can't call methods outside a method. Code like this cannot float around in the class.
You need something like:
public class MyClass {
UserInput input = new UserInput();
public void foo() {
input.name();
}
}
or inside a constructor:
public class MyClass {
UserInput input = new UserInput();
public MyClass() {
input.name();
}
}
for AndroidX use like
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:srcCompat="@drawable/ic_add" />
The Margin
property returns a Thickness
structure, of which Left
is a property. What the statement does is copying the structure value from the Margin
property and setting the Left
property value on the copy. You get an error because the value that you set will not be stored back into the Margin
property.
(Earlier versions of C# would just let you do it without complaining, causing a lot of questions in newsgroups and forums on why a statement like that had no effect at all...)
To set the property you would need to get the Thickness
structure from the Margin
property, set the value and store it back:
Thickness m = MyControl.Margin;
m.Left = 10;
MyControl.Margin = m;
If you are going to set all the margins, just create a Thickness
structure and set them all at once:
MyControl.Margin = new Thickness(10, 10, 10, 10);
I just had to deal with it myself. After all I found this method most easy and useful. Just add
overflow-x: hidden;
To your outer parent. In my case it looks like this:
<body style="overflow-x: hidden;">
You have to use overflow-x
because if you use simply use overflow
you disable the vertical scrolling too, namely overflow-y
If the vertical scrolling is still disabled you can enable it explicitly with:
overflow-y: scroll;
I know its somewhat not a proper way because if everything was setup well one would not have to use this quick and dirty method.
The solution suggested
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" >
<remove name="UrlRoutingModule"/>
</modules>
</system.webServer>
works, but can degrade performance and can even cause errors, because now all registered HTTP modules run on every request, not just managed requests (e.g. .aspx). This means modules will run on every .jpg .gif .css .html .pdf etc.
A more sensible solution is to include this in your web.config:
<system.webServer>
<modules>
<remove name="UrlRoutingModule-4.0" />
<add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
</modules>
</system.webServer>

Do not use css3 variables due to support.
I would do the following if you want a pure css solution.
Use color classes with semenatic names.
.bg-primary { background: #880000; }
.bg-secondary { background: #008800; }
.bg-accent { background: #F5F5F5; }
Separate the structure from the skin (OOCSS)
/* Instead of */
h1 {
font-size: 2rem;
line-height: 1.5rem;
color: #8000;
}
/* use this */
h1 {
font-size: 2rem;
line-height: 1.5rem;
}
.bg-primary {
background: #880000;
}
/* This will allow you to reuse colors in your design */
Put these inside a separate css file to change as needed.
The modern way:
new URL("http://example.com/aa/bb/")
Returns an object with properties hostname
and pathname
, along with a few others.
The first argument is a relative or absolute URL; if it's relative, then you need to specify the second argument (the base URL). For example, for a URL relative to the current page:
new URL("/aa/bb/", location)
In addition to browsers, this API is also available in Node.js since v7, through require('url').URL
.
The problem here is
if (stop = true)
is an assignation not a comparision.
Try if (stop == true)
Also take a look to the Top Ten Errors Java Programmers Make.
Here is your code for add data into both tableView:
import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet weak var table1Text: UITextField!
@IBOutlet weak var table2Text: UITextField!
@IBOutlet weak var table1: UITableView!
@IBOutlet weak var table2: UITableView!
var table1Data = ["a"]
var table2Data = ["1"]
override func viewDidLoad() {
super.viewDidLoad()
}
@IBAction func addData(sender: AnyObject) {
//add your data into tables array from textField
table1Data.append(table1Text.text)
table2Data.append(table2Text.text)
dispatch_async(dispatch_get_main_queue(), { () -> Void in
//reload your tableView
self.table1.reloadData()
self.table2.reloadData()
})
table1Text.resignFirstResponder()
table2Text.resignFirstResponder()
}
//delegate methods
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if tableView == table1 {
return table1Data.count
}else if tableView == table2 {
return table2Data.count
}
return Int()
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if tableView == table1 {
let cell = table1.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! UITableViewCell
let row = indexPath.row
cell.textLabel?.text = table1Data[row]
return cell
}else if tableView == table2 {
let cell = table2.dequeueReusableCellWithIdentifier("Cell1", forIndexPath: indexPath) as! UITableViewCell
let row = indexPath.row
cell.textLabel?.text = table2Data[row]
return cell
}
return UITableViewCell()
}
}
And your result will be:
checkip.dyndns.org is not always works correctly. For example, for my machine it shows internal after-NAT address:
Current IP Address: 192.168.1.120
I think its happening, because of I have my local DNS-zone behind NAT, and my browser sends to checkip its local IP address, which is returned back.
Also, http is heavy weight and text oriented TCP-based protocol, so not very suitable for quick and efficient regular request for external IP address. I suggest to use UDP-based, binary STUN, especially designed for this purposes:
http://en.wikipedia.org/wiki/STUN
STUN-server is like "UDP mirror". You looking to it, and see "how I looks".
There is many public STUN-servers over the world, where you can request your external IP. For example, see here:
http://www.voip-info.org/wiki/view/STUN
You can download any STUN-client library, from Internet, for example, here:
http://www.codeproject.com/Articles/18492/STUN-Client
And use it.
There is an isConnected function in BluetoothDevice system API in https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/BluetoothDevice.java
If you want to know if the a bounded(paired) device is currently connected or not, the following function works fine for me:
public static boolean isConnected(BluetoothDevice device) {
try {
Method m = device.getClass().getMethod("isConnected", (Class[]) null);
boolean connected = (boolean) m.invoke(device, (Object[]) null);
return connected;
} catch (Exception e) {
throw new IllegalStateException(e);
}
}
The tab character is \t
. Notice the use of "
instead of '
.
$chunk = "abc\tdef\tghi";
If the string is enclosed in double-quotes ("), PHP will interpret more escape sequences for special characters:
...
\t horizontal tab (HT or 0x09 (9) in ASCII)
Also, let me recommend the fputcsv() function which is for the purpose of writing CSV files.
You should create an exclude file for this. Check out this gist which is pretty self explanatory.
To address your question though, you may need to either de-index the .tmproj
file (if you've already added it to the index) with git rm --cached path/to/.tmproj
, or git add
and commit
your .gitignore
file.
Write-Host
is terrible, a destroyer of worlds, yet you can use it just to display progress to a user whilst using Write-Output
to log (not that the OP asked for logging).
Write-Output "Enabling feature XYZ" | Out-File "log.txt" # Pipe to log file
Write-Host -NoNewLine "Enabling feature XYZ......."
$result = Enable-SPFeature
$result | Out-File "log.txt"
# You could try{}catch{} an exception on Enable-SPFeature depending on what it's doing
if ($result -ne $null) {
Write-Host "complete"
} else {
Write-Host "failed"
}
You could try:
List<ManagementObject> managementList = new List<ManagementObject>(managementObjects.ToArray());
Not sure if .ToArray() is available for the collection. If you do use the code you posted, make sure you initialize the List with the number of existing elements:
List<ManagementObject> managementList = new List<ManagementObject>(managementObjects.Count); // or .Length
There are some great answers here, and so before I give my own I'd like to highlight a few of the gems (no ruby pun intended) I've read here.
len
is actually an object. Ruby, on the other hand, doesn't have first class functions. So the len
function object has it's own methods that you can inspect by running dir(len)
.If you don't like the way this works in your own code, it's trivial for you to re-implement the containers using your preferred method (see example below).
>>> class List(list):
... def len(self):
... return len(self)
...
>>> class Dict(dict):
... def len(self):
... return len(self)
...
>>> class Tuple(tuple):
... def len(self):
... return len(self)
...
>>> class Set(set):
... def len(self):
... return len(self)
...
>>> my_list = List([1,2,3,4,5,6,7,8,9,'A','B','C','D','E','F'])
>>> my_dict = Dict({'key': 'value', 'site': 'stackoverflow'})
>>> my_set = Set({1,2,3,4,5,6,7,8,9,'A','B','C','D','E','F'})
>>> my_tuple = Tuple((1,2,3,4,5,6,7,8,9,'A','B','C','D','E','F'))
>>> my_containers = Tuple((my_list, my_dict, my_set, my_tuple))
>>>
>>> for container in my_containers:
... print container.len()

A command is basically a string. In general it can be split into two parts - the command's name
and the command's arguments
.
Example:
ls
is used for listing the contents of a directory:
user@computer:~$ ls
Documents Pictures Videos ...
The ls
above is executed inside home
folder of a user. Here the argument which folder to list is implicitly added to the command. We can explicitly pass some arguments:
user@computer:~$ ls Picture
image1.jpg image2.jpg ...
Here I have explicitly told ls
which folder's contents I'd like to see. We can use another argument for example l
for listing the details of each file and folder such as access permissions, size etc.:
user@computer:~$ ls Pictures
-rw-r--r-- 1 user user 215867 Oct 12 2014 image1.jpg
-rw-r--r-- 1 user user 268800 Jul 31 2014 image2.jpg
...
Oh, the size looks really weird (215867
, 268800
). Let's add the h
flag for human-friendly output:
user@computer:~$ ls -l -h Pictures
-rw-r--r-- 1 user user 211K Oct 12 2014 image1.jpg
-rw-r--r-- 1 user user 263K Jul 31 2014 image2.jpg
...
Some commands allow their arguments to be combined (in the above case we might as well write ls -lh
and we'll get the same output), using short (a single letter usually but sometimes more; abbreviation) or long names (in case of ls
we have the -a
or --all
for listing all files including hidden ones with --all
being the long name for -a
) etc. There are commands where the order of the arguments is very important but there are also others where the order of the arguments is not important at all.
For example it doesn't matter if I use ls -lh
or ls -hl
however in the case of mv
(moving/renaming files) you have less flexibility for your last 2 arguments that is mv [OPTIONS] SOURCE DESTINATION
.
In order to get a grip of commands and their arguments you can use man
(example: man ls
) or info
(example: info ls
).
In many languages including C/C++ you have a way of parsing command line arguments that the user has attached to the call of the executable (the command). There are also numerous libraries available for this task since in its core it's actually not that easy to do it properly and at the same time offer a large amount of arguments and their varieties:
getopt
argp_parse
gflags
Every C/C++ application has the so called entry point, which is basically where your code starts - the main
function:
int main (int argc, char *argv[]) { // When you launch your application the first line of code that is ran is this one - entry point
// Some code here
return 0; // Exit code of the application - exit point
}
No matter if you use a library (like one of the above I've mentioned; but this is clearly not allowed in your case ;)) or do it on your own your main
function has the two arguments:
argc
- represents the number of argumentsargv
- a pointer to an array of strings (you can also see char** argv
which is basically the same but more difficult to use).NOTE: main
actually also has a third argument char *envp[]
which allows passing environment variables to your command but this is a more advanced thing and I really don't think that it's required in your case.
The processing of command line arguments consists of two parts:
ls -l
the l
is not only a valid character but also a token in itself since it represents a complete, valid argument.Here is an example how to output the number of arguments and the (unchecked for validity) characters that may or may not actually be arguments:
#include <iostream>
using std::cout;
using std::endl;
int main (int argc, char *argv[]) {
cout << "Arguments' count=%d" << argc << endl;
// First argument is ALWAYS the command itself
cout << "Command: " << argv[0] << endl;
// For additional arguments we start from argv[1] and continue (if any)
for (int i = 1; i < argc; i++) {
cout << "arg[" << i << "]: " << argv[i] << endl;
}
cout << endl;
return 0;
}
Parsing - after acquiring the tokens (arguments and their values) you need to check if your command supports these. For example:
user@computer:~$ ls -y
will return
ls: invalid option -- 'y'
Try 'ls --help' for more information.
This is because the parsing has failed. Why? Because y
(and -y
respectively; note that -
, --
, :
etc. is not required and its up to the parsing of the arguments whether you want that stuff there or not; in Unix/Linux systems this is a sort of a convention but you are not bind to it) is an unknown argument for the ls
command.
For each argument (if successfully recognized as such) you trigger some sort of change in your application. You can use an if-else
for example to check if a certain argument is valid and what it does followed by changing whatever you want that argument to change in the execution of the rest of your code. You can go the old C-style or C++-style:
* `if (strcmp(argv[1], "x") == 0) { ... }` - compare the pointer value
* `if (std::string(argv[1]) == "x") { ... }` - convert to string and then compare
I actually like (when not using a library) to convert argv
to an std::vector
of strings like this:
std::vector<std::string> args(argv, argv+argc);
for (size_t i = 1; i < args.size(); ++i) {
if (args[i] == "x") {
// Handle x
}
else if (args[i] == "y") {
// Handle y
}
// ...
}
The std::vector<std::string> args(argv, argv+argc);
part is just an easier C++-ish way to handle the array of strings since char *
is a C-style string (with char *argv[]
being an array of such strings) which can easily be converted to a C++ string that is std::string
. Then we can add all converted strings to a vector by giving the starting address of argv
and then also pointing to its last address namely argv + argc
(we add argc
number of string to the base address of argv
which is basically pointing at the last address of our array).
Inside the for
loop above you can see that I check (using simple if-else
) if a certain argument is available and if yes then handle it accordingly. A word of caution: by using such a loop the order of the arguments doesn't matter. As I've mentioned at the beginning some commands actually have a strict order for some or all of their arguments. You can handle this in a different way by manually calling the content of each args
(or argv
if you use the initial char* argv[]
and not the vector solution):
// No for loop!
if (args[1] == "x") {
// Handle x
}
else if (args[2] == "y") {
// Handle y
}
// ...
This makes sure that at position 1
only the x
will be expected etc. The problem with this is that you can shoot yourself in the leg by going out of bounds with the indexing so you have to make sure that your index stays within the range set by argc
:
if (argc > 1 && argc <= 3) {
if (args[1] == "x") {
// Handle x
}
else if (args[2] == "y") {
// Handle y
}
}
The example above makes sure you have content at index 1
and 2
but not beyond.
Last but not least the handling of each argument is a thing that is totally up to you. You can use boolean flags that are set when a certain argument is detected (example: if (args[i] == "x") { xFound = true; }
and later on in your code do something based on the bool xFound
and its value), numerical types if the argument is a number OR consists of number along with the argument's name (example: mycommand -x=4
has an argument -x=4
which you can additionally parse as x
and 4
the last being the value of x
) etc. Based on the task at hand you can go crazy and add an insane amount of complexity to your command line arguments.
Hope this helps. Let me know if something is unclear or you need more examples.

Years later, but a useful option would be to utilize XPath Axes (https://www.w3schools.com/xml/xpath_axes.asp). More specifically, you are looking to use the descendants axes.
I believe this example would do the trick:
//book[descendant::title[@lang='it']]
This allows you to select all book
elements that contain a child title
element (regardless of how deep it is nested) containing language attribute value equal to 'it'.
I cannot say for sure whether or not this answer is relevant to the year 2009 as I am not 100% certain that the XPath Axes existed at that time. What I can confirm is that they do exist today and I have found them to be extremely useful in XPath navigation and I am sure you will as well.
If you are needing to use CSS with the jQuery .animate()
function, you can use set the duration.
$("#my_image").css({
'left':'1000px',
6000, ''
});
We have the duration property set to 6000.
This will set the time in thousandth of seconds: 6 seconds.
After the duration our next property "easing" changes how our CSS happens.
We have our positioning set to absolute.
There are two default ones to the absolute function: 'linear' and 'swing'.
In this example I am using linear.
It allows for it to use a even pace.
The other 'swing' allows for a exponential speed increase.
There are a bunch of really cool properties to use with animate like bounce, etc.
$(document).ready(function(){
$("#my_image").css({
'height': '100px',
'width':'100px',
'background-color':'#0000EE',
'position':'absolute'
});// property than value
$("#my_image").animate({
'left':'1000px'
},6000, 'linear', function(){
alert("Done Animating");
});
});
Quick fix that works for me. Navigate to the root directory of your folder from command line (cmd). then once you are on your root directory, type:
code .
Then, press enter. Note the ".", don't forget it. Now try to debug and see if you get the same error.

Short version: it's marking that hash as attached to the current package namespace (so that that package provides its class implementation).
Reproducible code is key to get help. However, there are many users that might be skeptical of pasting even a chunk of their data. For instance, they could be working with sensitive data or on an original data collected to use in a research paper. For any reason, I thought it would be nice to have a handy function for "deforming" my data before pasting it publicly. The anonymize
function from the package SciencesPo
is very silly, but for me it works nicely with dput
function.
install.packages("SciencesPo")
dt <- data.frame(
Z = sample(LETTERS,10),
X = sample(1:10),
Y = sample(c("yes", "no"), 10, replace = TRUE)
)
> dt
Z X Y
1 D 8 no
2 T 1 yes
3 J 7 no
4 K 6 no
5 U 2 no
6 A 10 yes
7 Y 5 no
8 M 9 yes
9 X 4 yes
10 Z 3 no
Then I anonymize it:
> anonymize(dt)
Z X Y
1 b2 2.5 c1
2 b6 -4.5 c2
3 b3 1.5 c1
4 b4 0.5 c1
5 b7 -3.5 c1
6 b1 4.5 c2
7 b9 -0.5 c1
8 b5 3.5 c2
9 b8 -1.5 c2
10 b10 -2.5 c1
One may also want to sample few variables instead of the whole data before apply anonymization and dput command.
# sample two variables without replacement
> anonymize(sample.df(dt,5,vars=c("Y","X")))
Y X
1 a1 -0.4
2 a1 0.6
3 a2 -2.4
4 a1 -1.4
5 a2 3.6
you can use download attribute to force download a file:

As @StahlRat already answered. I would like to add another method for it. There is extension pack for Python Default idle editor Python Extensions Package.
You are trying to set "++" on a jQuery element!
YOu could declare a js variable
var counter = 0;
and in jQuery code do:
$("#counter").html(counter++);
Using the trick
Attribute VB_PredeclaredId = True
I found another more compact way:
Option Explicit
Option Base 0
Option Compare Binary
Private v_cBox As ComboBox
'
' Class creaor
Public Function New_(ByRef cBox As ComboBox) As ComboBoxExt_c
If Me Is ComboBoxExt_c Then
Set New_ = New ComboBoxExt_c
Call New_.New_(cBox)
Else
Set v_cBox = cBox
End If
End Function
As you can see the New_ constructor is called to both create and set the private members of the class (like init) only problem is, if called on the non-static instance it will re-initialize the private member. but that can be avoided by setting a flag.
You could as well take an alternative approach -- you don't have to use $http, you don't need any extra libraries, and it ought to work in any browser.
Just place an invisible form on your page.
<form name="downloadForm" action="/MyApp/MyFiles/Download" method="post" target="_self">
<input type="hidden" name="value1" value="{{ctrl.value1}}" />
<input type="hidden" name="value2" value="{{ctrl.value2}}" />
</form>
And place this code in your angular controller.
ctrl.value1 = 'some value 1';
ctrl.value2 = 'some value 2';
$timeout(function () {
$window.document.forms['downloadForm'].submit();
});
This code will post your data to /MyApp/MyFiles/Download and you'll receive a file in your Downloads folder.
It works with Internet Explorer 10.
If a conventional HTML form doesn't let you post your complex object, then you have two options:
1. Stringify your object and put it into one of the form fields as a string.
<input type="hidden" name="myObjJson" value="{{ctrl.myObj | json:0}}" />
2. Consider HTML JSON forms: https://www.w3.org/TR/html-json-forms/
use this in style
body
{
overflow:hidden;
width:100%;
}
Use this in head tag
<meta name="viewport" content="user-scalable=no, width=device-width, initial-scale=1.0" />
<meta name="apple-mobile-web-app-capable" content="yes" />
If you want to hide just the axis text keeping the grid lines:
frame1 = plt.gca()
frame1.axes.xaxis.set_ticklabels([])
frame1.axes.yaxis.set_ticklabels([])
Doing set_visible(False)
or set_ticks([])
will also hide the grid lines.
UPDATE: Please note that this is a solution that should apply to older browsers or non-browser platforms, and is kept alive for instructional purposes. Please refer to @radicand 's answer below for a more up to date answer.
This is a unicode, escaped string. First the string was escaped, then encoded with unicode. To convert back to normal:
var x = "http\\u00253A\\u00252F\\u00252Fexample.com";
var r = /\\u([\d\w]{4})/gi;
x = x.replace(r, function (match, grp) {
return String.fromCharCode(parseInt(grp, 16)); } );
console.log(x); // http%3A%2F%2Fexample.com
x = unescape(x);
console.log(x); // http://example.com
To explain: I use a regular expression to look for \u0025
. However, since I need only a part of this string for my replace operation, I use parentheses to isolate the part I'm going to reuse, 0025
. This isolated part is called a group.
The gi
part at the end of the expression denotes it should match all instances in the string, not just the first one, and that the matching should be case insensitive. This might look unnecessary given the example, but it adds versatility.
Now, to convert from one string to the next, I need to execute some steps on each group of each match, and I can't do that by simply transforming the string. Helpfully, the String.replace operation can accept a function, which will be executed for each match. The return of that function will replace the match itself in the string.
I use the second parameter this function accepts, which is the group I need to use, and transform it to the equivalent utf-8 sequence, then use the built - in unescape
function to decode the string to its proper form.
