Java 7 and up supports the Path
class (in java.nio package).
You can use this class to convert a string-path to one that works for your current OS.
Using:
Paths.get("\\folder\\subfolder").toString()
on a Unix machine, will give you /folder/subfolder
. Also works the other way around.

I had issues with spaces showing in between my output and there was no answer online at all to fix this issue. I literally spend many hours trying to find a solution and found one from playing around with the code to the point that I almost did not even know what I typed in at the time that I got it to work. Here is my fix for the issue: [System.Text.Encoding]::UTF8.GetString(([System.Convert]::FromBase64String($base64string)|?{$_}))
LDPI should be 36 x 36.
MDPI 48 x 48.

Check out here for dump. It seems there is a dump function in the library sqlite3.
It’s about time someone provides the modern answer. The modern solution uses java.time, the modern Java date and time API. The classes SimpleDateFormat
and Date
used in the question and in a couple of the other answers are poorly designed and long outdated, the former in particular notoriously troublesome. TimeZone
is poorly designed to. I recommend you avoid those.
ZoneId utc = ZoneId.of("Etc/UTC");
DateTimeFormatter targetFormatter = DateTimeFormatter.ofPattern(
"MM/dd/yyyy hh:mm:ss a zzz", Locale.ENGLISH);
String itsAlarmDttm = "2013-10-22T01:37:56";
ZonedDateTime utcDateTime = LocalDateTime.parse(itsAlarmDttm)
.atZone(ZoneId.systemDefault())
.withZoneSameInstant(utc);
String formatterUtcDateTime = utcDateTime.format(targetFormatter);
System.out.println(formatterUtcDateTime);
When running in my time zone, Europe/Copenhagen, the output is:
10/21/2013 11:37:56 PM UTC
I have assumed that the string you got was in the default time zone of your JVM, a fragile assumption since that default setting can be changed at any time from another part of your program or another programming running in the same JVM. If you can, instead specify time zone explicitly, for example ZoneId.of("Europe/Podgorica")
or ZoneId.of("Asia/Kolkata")
.
I am exploiting the fact that you string is in ISO 8601 format, the format the the modern classes parse as their default, that is, without any explicit formatter.
I am using a ZonedDateTime
for the result date-time because it allows us to format it with UTC
in the formatted string to eliminate any and all doubt. For other purposes one would typically have wanted an OffsetDateTime
or an Instant
instead.

LocalDate.now() // Capture the date-only value current in the JVM’s current default time zone.

Both the java.util.Date
and java.util.Calendar
classes are legacy, now supplanted by the java.time framework built into Java 8 and later.
A time zone is crucial in determining a date. For any given moment, the date varies around the globe by zone. For example, a few minutes after midnight in Paris France is a new day while still “yesterday” in Montréal Québec.
If no time zone is specified, the JVM implicitly applies its current default time zone. That default may change at any moment, so your results may vary. Better to specify your desired/expected time zone explicitly as an argument.
Specify a proper time zone name in the format of continent/region
, such as America/Montreal
, Africa/Casablanca
, or Pacific/Auckland
. Never use the 3-4 letter abbreviation such as EST
or IST
as they are not true time zones, not standardized, and not even unique(!).
ZoneId z = ZoneId.of( "Africa/Tunis" ) ;
If you want only the date without time-of-day, use LocalDate
. This class lacks time zone info but you can specify a time zone to determine the current date.
ZoneId zoneId = ZoneId.of( "America/Montreal" );
LocalDate localDate = LocalDate.now( zoneId );
You can get the various pieces of information with getYear
, getMonth
, and getDayOfMonth
. You will actually get the year number with java.time!
int year = localDate.getYear();
2016
If you want a date-time instead of just a date, use ZonedDateTime
class.
ZonedDateTime zdt = ZonedDateTime.now( zoneId ) ;
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old date-time classes such as java.util.Date
, .Calendar
, & java.text.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.
Much of the java.time functionality is back-ported to Java 6 & Java 7 in ThreeTen-Backport and further adapted to Android in ThreeTenABP (see How to use…).
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.

If you don't have 'HIBERNATE_SEQUENCE' sequence created in database (if use oracle or any sequence based database), you shall get same type of error;
Ensure the sequence is present there;
I just created a new cluster and that worked for me, I was using (PostgreSQL) 9.3.20:

Probably the worst python line I've written so far:
f = lambda x: sys.stdout.write(["2\n",][2*(x==2)-2])
If x == 2 you print,
if x != 2 you raise.
If you want to store these time in a database or send it over the server...best is to use Unix timestamps. Here's a little snippet to get that:
+ (NSTimeInterval)getUTCFormateDate{
NSDateComponents *comps = [[NSCalendar currentCalendar]
components:NSDayCalendarUnit | NSYearCalendarUnit | NSMonthCalendarUnit
fromDate:[NSDate date]];
[comps setHour:0];
[comps setMinute:0];
[comps setSecond:[[NSTimeZone systemTimeZone] secondsFromGMT]];
return [[[NSCalendar currentCalendar] dateFromComponents:comps] timeIntervalSince1970];
}
For other types, check out the types module:
>>> import types
>>> x = "mystring"
>>> isinstance(x, types.StringType)
True
>>> x = 5
>>> isinstance(x, types.IntType)
True
>>> x = None
>>> isinstance(x, types.NoneType)
True

As far as your question goes: no, if activating from .ini
is not enough and you can't upgrade PHP, there's not much you can do. Some modules, but not all, can be added without recompilation (zypper install php5-soap
, yum install php-soap
). If it is not enough, try installing some PEAR class for interpreted SOAP support (NuSOAP, etc.).
In general, the double-dash --switches
are designed to be used when recompiling PHP from scratch.
You would download the PHP source package (as a compressed .tgz
tarball, say), expand it somewhere and then, e.g. under Linux, run the configure script
./configure --prefix ...
The configure
command used by your PHP may be shown with phpinfo()
. Repeating it identical should give you an exact copy of the PHP you now have installed. Adding --enable-soap
will then enable SOAP in addition to everything else.
That said, if you aren't familiar with PHP recompilation, don't do it. It also requires several ancillary libraries that you might, or might not, have available - freetype
, gd
, libjpeg
, XML
, expat
, and so on and so forth (it's not enough they are installed; they must be a developer version, i.e. with headers and so on; in most distributions, having libjpeg
installed might not be enough, and you might need libjpeg-dev
also).
I have to keep a separate virtual machine with everything installed for my recompilation purposes.
I wrote a small helper method to read Paths
from your class resources. It is quite handy to use as it only needs a reference of the class you have stored your resources as well as the name of the resource itself.
public static Path getResourcePath(Class<?> resourceClass, String resourceName) throws URISyntaxException {
URL url = resourceClass.getResource(resourceName);
return Paths.get(url.toURI());
}
You may find this to be more common on CIFS/SMB network shares. Windows doesn't allow for a file to be written when something else has that file open, and even if the service is not Windows (it might be some other NAS product), it will likely reproduce the same behaviour. Potentially, it might also be a manifestation of some underlying NAS issue vaguely related to locking/replication.
You should just use
numStars="5"
in your XML, and set
android:layout_width="wrap_content"
.
Then, you can play around with styles and other stuff, but the "wrap_content" in layout_width is what does the trick.
Do the following steps:
Download the Flutter SDK Flutter SDK Archive
Extract it where do you want (for example /home/development/flutter
)
Set your PATH, edit your file with this command gedit ~/.profile
, you need to add this line
export PATH=[location_where_you_extracted_flutter]/flutter/bin:$PATH
I showed you above where I've extracted mine, so my export will look like this
export PATH=/home/myUser/development/flutter/bin:$PATH

So yes, ArrayList.clear
is much faster.
Length of characters to be matched.
{n,m} n <= length <= m
{n} length == n
{n,} length >= n
And by default, the engine is greedy to match this pattern. For example, if the input is 123456789, \d{2,5} will match 12345 which is with length 5.
If you want the engine returns when length of 2 matched, use \d{2,5}?

By combining the multicol package and enumitem package packages it is easy to define environments that are multi-column analogues of the enumerate and itemize environments:
\documentclass{article}
\usepackage{enumitem}
\usepackage{multicol}
\newlist{multienum}{enumerate}{1}
\setlist[multienum]{
label=\alph*),
before=\begin{multicols}{2},
after=\end{multicols}
}
\newlist{multiitem}{itemize}{1}
\setlist[multiitem]{
label=\textbullet,
before=\begin{multicols}{2},
after=\end{multicols}
}
\begin{document}
\textsf{Two column enumerate}
\begin{multienum}
\item item 1
\item item 2
\item item 3
\item item 4
\item item 5
\item item 6
\end{multienum}
\textsf{Two column itemize}
\begin{multiitem}
\item item 1
\item item 2
\item item 3
\item item 4
\item item 5
\item item 6
\end{multiitem}
\end{document}
The output is what you would hope for:
Using find
's -regex
argument:
find . -regex '.*/Robert\.\(h\|cpp\)$'
Or just using -name
:
find . -name 'Robert.*' -a \( -name '*.cpp' -o -name '*.h' \)
The essential idea here is to select the data you want to sum, and then sum them. This selection of data can be done in several different ways, a few of which are shown below.
Arguably the most common way to select the values is to use Boolean indexing.
With this method, you find out where column 'a' is equal to 1
and then sum the corresponding rows of column 'b'. You can use loc
to handle the indexing of rows and columns:
>>> df.loc[df['a'] == 1, 'b'].sum()
15
The Boolean indexing can be extended to other columns. For example if df
also contained a column 'c' and we wanted to sum the rows in 'b' where 'a' was 1 and 'c' was 2, we'd write:
df.loc[(df['a'] == 1) & (df['c'] == 2), 'b'].sum()
Another way to select the data is to use query
to filter the rows you're interested in, select column 'b' and then sum:
>>> df.query("a == 1")['b'].sum()
15
Again, the method can be extended to make more complicated selections of the data:
df.query("a == 1 and c == 2")['b'].sum()
Note this is a little more concise than the Boolean indexing approach.
The alternative approach is to use groupby
to split the DataFrame into parts according to the value in column 'a'. You can then sum each part and pull out the value that the 1s added up to:
>>> df.groupby('a')['b'].sum()[1]
15
This approach is likely to be slower than using Boolean indexing, but it is useful if you want check the sums for other values in column a
:
>>> df.groupby('a')['b'].sum()
a
1 15
2 8
This should be faster.

Add it in your root build.gradle at the end of repositories:

app:sparkbutton_inActiveImage="@drawable/inactive_image"
app:sparkbutton_iconSize="40dp"

SparkButton button = new SparkButtonBuilder(context)
.setActiveImage(R.drawable.active_image)
.setInActiveImage(R.drawable.inactive_image)
.setDisabledImage(R.drawable.disabled_image)
.setImageSizePx(getResources().getDimensionPixelOffset(R.dimen.button_size))
.setPrimaryColor(ContextCompat.getColor(context, R.color.primary_color))
.setSecondaryColor(ContextCompat.getColor(context, R.color.secondary_color))
.build();
If you want to execute that command, you should probably change:
PROCESS_NUM='ps -ef | grep "$1" | grep -v "grep" | wc -l'
to:
PROCESS_NUM=$(ps -ef | grep "$1" | grep -v "grep" | wc -l)

First create an object of class2 in class1 and then use that object to call any function of class2 for example write this in class1
class2 obj= new class2();
obj.thefunctioname(args);
There are a couple ways you can deal with this. First, and perhaps best, is to rework your equation so that it is not so long; it is likely unreadable if it is that long.
If it must be so, check out the AMS Short Math Guide for some ways to handle it. (on the second page)
Personally, I'd use an align environment, so that the breaking and alignment can be precisely controlled. e.g.
\begin{align*}
x&+y+\dots+\dots+x_100000000\\
&+x_100000001+\dots+\dots
\end{align*}
which would line up the first plus signs of each line... but obviously, you can set the alignments wherever you like.
Libraries exist to do this, but the simplest plain Java way is to create a Map
of List
like this:
Map<Object,ArrayList<Object>> multiMap = new HashMap<>();
You have to use a Class
instance because of the generic type erasure during compilation.
public static <T> T convertInstanceOfObject(Object o, Class<T> clazz) {
try {
return clazz.cast(o);
} catch(ClassCastException e) {
return null;
}
}
The declaration of that method is:
public T cast(Object o)
This can also be used for array types. It would look like this:
final Class<int[]> intArrayType = int[].class;
final Object someObject = new int[]{1,2,3};
final int[] instance = convertInstanceOfObject(someObject, intArrayType);
Note that when someObject
is passed to convertToInstanceOfObject
it has the compile time type Object
.
I did this for a home folder where all the folders are on the desktops of the corresponding users, reachable through a shortcut which did not have the appropriate permissions, so that users couldn't see it even if it was there. So I used Robocopy with the parameter to overwrite the file with the right settings:
FOR /F "tokens=*" %G IN ('dir /b') DO robocopy "\\server02\Folder with shortcut" "\\server02\home\%G\Desktop" /S /A /V /log+:C:\RobocopyShortcut.txt /XF *.url *.mp3 *.hta *.htm *.mht *.js *.IE5 *.css *.temp *.html *.svg *.ocx *.3gp *.opus *.zzzzz *.avi *.bin *.cab *.mp4 *.mov *.mkv *.flv *.tiff *.tif *.asf *.webm *.exe *.dll *.dl_ *.oc_ *.ex_ *.sy_ *.sys *.msi *.inf *.ini *.bmp *.png *.gif *.jpeg *.jpg *.mpg *.db *.wav *.wma *.wmv *.mpeg *.tmp *.old *.vbs *.log *.bat *.cmd *.zip /SEC /IT /ZB /R:0
As you see there are many file types which I set to ignore (just in case), just set them for your needs or your case scenario.
It was tested on Windows Server 2012, and every switch is documented on Microsoft's sites and others.
You can try this:
#!/bin/sh
nohup java -jar /web/server.jar &
The & symbol, switches the program to run in the background.
The nohup utility makes the command passed as an argument run in the background even after you log out.
I am not a javascript person, but I found here for searching this problem. For who google it and find here, I am hoping that this helps some. So, as in question if we have a list of radio buttons:
<div class="list">
<input type="radio" name="b1" value="1">
<input type="radio" name="b2" value="2" checked="checked">
<input type="radio" name="b3" value="3">
</div>
I can find which one selected with this selector:
$('.list input[type="radio"]:checked:first').val();
Even if there is no element selected, I still don't get undefined error. So, you don't have to write extra if statement before taking element's value.
Here is very basic jsfiddle example.
I personally tried all the answers mentioned above, but most of them were a bit complex or just not right. The easiest way to do it from my point of view is:
awk -F" " '{ for (i=4; i<=NF; i++) print $i }'
Where -F" " defines the delimiter for awk to use. In my case is the whitespace, which is also the default delimiter for awk. This means that -F" " can be ignored.
Where NF defines the total number of fields/columns. Therefore the loop will begin from the 4th field up to the last field/column.
Where $N retrieves the value of the Nth field. Therefore print $i will print the current field/column based based on the loop count.
You can use the ruby method:
:root_url
which will get the full path with base url:
localhost:3000/bla
There is a confusion that is causing a lot of TortoiseSVN users to use the wrong command line tools when they actually were looking for svn.exe
command line client.
What should I do or can't TortoiseSVN be used from the command line?
If you want to run Subversion commands from the command prompt, you should run the svn.exe
command line client. TortoiseSVN 1.6.x and older versions did not include SVN command-line tools, but modern versions do.
If you want to get SVN command line tools without having to install TortoiseSVN, check the SVN binary distributions page or simply download the latest version from VisualSVN downloads page.
If you have SVN command line tools installed on your system, but still get the error 'svn' is not recognized as an internal or external command
, you should check %PATH%
environment variable. %PATH%
must include the path to SVN tools directory e.g. C:\Program Files (x86)\VisualSVN\bin
.
Apart from svn.exe
, TortoiseSVN comes with TortoiseProc.exe
that can be called from command prompt. In most cases, you do not need to use this tool, because it should be only used for GUI automation. TortoiseProc.exe
is not a replacement for SVN command-line client.
This worked for me. A combination of some of the answers here. And I included the code showing a model only once. And the model goes away when clicked anywhere else.
<script>
var leave = 0
//show modal when mouse off of page
$("html").mouseleave(function() {
//check for first time
if (leave < 1) {
modal.style.display = "block";
leave = leave + 1;
}
});
// Get the modal with id="id01"
var modal = document.getElementById('id01');
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
</script>

Here is an even simpler solution using base graphics and alpha-blending (which does not work on all graphics devices):
set.seed(42)
p1 <- hist(rnorm(500,4)) # centered at 4
p2 <- hist(rnorm(500,6)) # centered at 6
plot( p1, col=rgb(0,0,1,1/4), xlim=c(0,10)) # first histogram
plot( p2, col=rgb(1,0,0,1/4), xlim=c(0,10), add=T) # second
The key is that the colours are semi-transparent.
Edit, more than two years later: As this just got an upvote, I figure I may as well add a visual of what the code produces as alpha-blending is so darn useful:
Update: I noticed that my answer was just a poor duplicate of a well explained question on https://unix.stackexchange.com/... by BryKKan

Use "target" attribute and remove the 'compiler' attribute. See here. So it should go something like this:

You can use this JDBC URL directly in your data source configuration:
jdbc:mysql://yourserver:3306/yourdatabase?zeroDateTimeBehavior=convertToNull
I have tried many solutions but the one i came up with is this:
DirectoryIndex index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|(.*)\.swf|forums|images|css|downloads|jquery|js|robots \.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php?$1 [L,QSA]
This iwill remove the index.php from the url as required.
In general, embed is good if you have one-to-one or one-to-many relationships between entities, and reference is good if you have many-to-many relationships.
In PHP functions will not be evaluated inside strings, because there are different rules for variables.
<?php
function name() {
return 'Mark';
}
echo 'My name is: name()'; // Output: My name is name()
echo 'My name is: '. name(); // Output: My name is Mark
The action parameter to the tag in HTML should not reference the PHP function you want to run. Action should refer to a page on the web server that will process the form input and return new HTML to the user. This can be the same location as the PHP script that outputs the form, or some people prefer to make a separate PHP file to handle actions.
The basic process is the same either way:
A simple example would be:
<?php
// $_POST is a magic PHP variable that will always contain
// any form data that was posted to this page.
// We check here to see if the textfield called 'name' had
// some data entered into it, if so we process it, if not we

function print_name($name) {
// $name should be validated and checked here depending on use.
// In this case we just HTML escape it so nothing nasty should

// This function is called when no name was sent to us over HTTP.
function print_form() {

For future information I recommend reading the PHP tutorials: http://php.net/tut.php
There is even a section about Dealing with forms.
inside the Form, You can use this code. Replace your variable name (i use $variable)
<input type="text" value="<?php echo (isset($variable))?$variable:'';?>">
Since one div is initially hidden, you can simply call toggle for both divs:
<a href="javascript:void(0);" id="forgot-password">forgot password?</a>
<div id="login-form">login form</div>
<div id="recover-password" style="display:none;">recover password</div>
<script type="text/javascript">
$(function(){
$('#forgot-password').click(function(){
$('#login-form').toggle();
$('#recover-password').toggle();
});
});
</script>
Generally you compile most .c files in the following way:
gcc foo.c -o foo. It might vary depending on what #includes you used or if you have any external .h files. Generally, when you have a C file, it looks somewhat like the following:
#include <stdio.h>
/* any other includes, prototypes, struct delcarations... */
int main(){
*/ code */
}
When I get an 'undefined reference to main', it usually means that I have a .c file that does not have int main()
in the file. If you first learned java, this is an understandable manner of confusion since in Java, your code usually looks like the following:
//any import statements you have
public class Foo{
int main(){}
}
I would advise looking to see if you have int main()
at the top.
It's considered poor form. Use a list comprehension instead, with slice assignment if you need to retain existing references to the list.
a = [1, 3, 5]
b = a
a[:] = [x + 2 for x in a]
print(b)
SetTimeout is used to make your set of code to execute after a specified time period so for your requirements its better to use setInterval because that will call your function every time at a specified time interval.
I am using httpclient 4.4.
For solr query I used the following way and it worked.
NameValuePair nv2 = new BasicNameValuePair("fq","(active:true) AND (category:Fruit OR category1:Vegetable)");
nvPairList.add(nv2);
NameValuePair nv3 = new BasicNameValuePair("wt","json");
nvPairList.add(nv3);
NameValuePair nv4 = new BasicNameValuePair("start","0");
nvPairList.add(nv4);
NameValuePair nv5 = new BasicNameValuePair("rows","10");
nvPairList.add(nv5);
HttpClient client = HttpClientBuilder.create().build();
HttpGet request = new HttpGet(url);
URI uri = new URIBuilder(request.getURI()).addParameters(nvPairList).build();
request.setURI(uri);
HttpResponse response = client.execute(request);
if (response.getStatusLine().getStatusCode() != 200) {
}
BufferedReader br = new BufferedReader(
new InputStreamReader((response.getEntity().getContent())));
String output;
System.out.println("Output .... ");
String respStr = "";
while ((output = br.readLine()) != null) {
respStr = respStr + output;
System.out.println(output);
}
ls -l --block-size=M will give you a long format listing (needed to actually see the file size) and round file sizes up to the nearest MiB.
If you want MB (10^6 bytes) rather than MiB (2^20 bytes) units, use --block-size=MB instead.
If you don't want the M suffix attached to the file size, you can use something like --block-size=1M. Thanks Stéphane Chazelas for suggesting this.
This is described in the man page for ls; man ls and search for SIZE. It allows for units other than MB/MiB as well, and from the looks of it (I didn't try that) arbitrary block sizes as well (so you could see the file size as number of 412-byte blocks, if you want to).
Note that the --block-size parameter is a GNU extension on top of the Open Group's ls, so this may not work if you don't have a GNU userland (which most Linux installations do). The ls from GNU coreutils 8.5 does support --block-size as described above.
What suited my purpose was to create a div that was always bounded within the overall browser window by a fixed amount.
What worked, at least on firefox, was this
<div style="position: absolute; top: 127px; left: 75px;right: 75px; bottom: 50px;">
Insofar as the actual window is not forced into scrolling, the div preserves its boundaries to the window edge during all re-sizing.
Hope this saves someone some time.
I've found my ssh.exe in "C:/Program Files/Git/usr/bin" directory
You can use:
For example:
// simple class who output his value
class ConsoleOutput
{
public:
ConsoleOutput(int value):m_value(value) { }
int Value() const { return m_value; }
private:
int m_value;
};
// functional object
class Predicat
{
public:
void operator()(ConsoleOutput const& item)
{
std::cout << item.Value() << std::endl;
}
};
void main()
{
// fill list
std::vector<ConsoleOutput> list;
list.push_back(ConsoleOutput(1));
list.push_back(ConsoleOutput(8));
// 1) using size_t
for (size_t i = 0; i < list.size(); ++i)
{
std::cout << list.at(i).Value() << std::endl;
}
// 2) iterators + distance, for std::distance only non const iterators
std::vector<ConsoleOutput>::iterator itDistance = list.begin(), endDistance = list.end();
for ( ; itDistance != endDistance; ++itDistance)
{
// int or size_t
int const position = static_cast<int>(std::distance(list.begin(), itDistance));
std::cout << list.at(position).Value() << std::endl;
}
// 3) iterators
std::vector<ConsoleOutput>::const_iterator it = list.begin(), end = list.end();
for ( ; it != end; ++it)
{
std::cout << (*it).Value() << std::endl;
}
// 4) functional objects
std::for_each(list.begin(), list.end(), Predicat());
}
Just pointing out that it is use of parentheses that invokes auto-concatenation. That's fine if you happen to already be using them in the statement. Otherwise, I would just use '\' rather than inserting parentheses (which is what most IDEs do for you automatically). The indent should align the string continuation so it is PEP8 compliant. E.g.:
my_string = "The quick brown dog " \
"jumped over the lazy fox"
Python Counter is also a good option in this case:
from collections import Counter
counter = Counter(["Sachin Tendulkar", "Sachin Tendulkar", "other things"])
print(counter)
This returns a dict with the count of each element in the list:
Counter({'Sachin Tendulkar': 2, 'other things': 1})
Download and install LINQPad, it works for SQL Server, MySQL, SQLite and also SDF (SQL CE 4.0).
Steps for open SDF Files:

Select Build data context automatically and Default (LINQ to SQL), then Next.
Under Provider choose SQL CE 4.0.
Under Database with Attach database file selected, choose Browse to select your .sdf file.
Click OK.
CSS is your friend; there is no need for the center tag (not to mention it is quite depreciated) nor the excessive non-breaking spaces. Here is a simple example:
CSS
.images {
text-align:center;
}
.images img {
width:100px;
height:100px;
}
.images div {
width:100px;
text-align:center;
}
.images div span {
display:block;
}
.margin_right {
margin-right:50px;
}
.float {
float:left;
}
.clear {
clear:both;
height:0;
width:0;
}
HTML
<div class="images">
<div class="float margin_right">
<a href="http://xyz.com/hello"><img src="hello.png" width="100px" height="100px" /></a>
<span>This is some text</span>
</div>
<div class="float">
<a href="http://xyz.com/hi"><img src="hi.png" width="100px" height="100px" /></a>
<span>And some more text</span>
</div>
<span class="clear"></span>
</div>
It turns out that you don’t have to run the command again as Administrator, and doing so won’t fix the problem.
Try:
npm cache clean
first.
If that doesn’t fix things, take a look in %APPDATA%\npm-cache
, or if you’re using PowerShell, $env:APPDATA\npm-cache
.
After cleaning the cache, you may still be left with remnants. Manually remove everything in that directory, and try again. This has always fixed things for me.
As @Crazzymatt was mentioning, as of the npm@5 version and up, we need to use npm cache verify
instead of npm cache clean
. Or else you will get an error as preceding.
npm ERR! As of npm@5, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid. If you want to make sure everything is consistent, use 'npm cache verify' instead.

If you do not want to use Calendar class at all you can use this
String weekday_name = new SimpleDateFormat("EEEE", Locale.ENGLISH).format(System.currentTimeMillis());
i.e., result is,
"Sunday"
I think the answer depends on which features of stored procedures you need to use.
Stored procedures returning a result set can be run using Query
; stored procedures which don't return a result set can be run using Execute
- in both cases (using EXEC <procname>
) as the SQL command (plus input parameters as necessary). See the documentation for more details.
As of revision 2d128ccdc9a2 there doesn't appear to be native support for OUTPUT
parameters; you could add this, or alternatively construct a more complex Query
command which declared TSQL variables, executed the SP collecting OUTPUT
parameters into the local variables and finallyreturned them in a result set:
DECLARE @output int
EXEC <some stored proc> @i = @output OUTPUT
SELECT @output AS output1
The default behavior is:
If the parameter is a primitive type (int
, bool
, double
, ...), Web API tries to get the value from the URI of the HTTP request.
For complex types (your own object, for example: Person
), Web API tries to read the value from the body of the HTTP request.
So, if you have:
...then you don't have to add any attributes (neither [FromBody]
nor [FromUri]
).
But, if you have a primitive type in the body, then you have to add [FromBody]
in front of your primitive type parameter in your WebAPI controller method. (Because, by default, WebAPI is looking for primitive types in the URI of the HTTP request.)
Or, if you have a complex type in your URI, then you must add [FromUri]
. (Because, by default, WebAPI is looking for complex types in the body of the HTTP request by default.)
Primitive types:
public class UsersController : ApiController
{
// api/users
public HttpResponseMessage Post([FromBody]int id)
{
}
// api/users/id
public HttpResponseMessage Post(int id)
{
}
}
Complex types:
public class UsersController : ApiController
{
// api/users
public HttpResponseMessage Post(User user)
{
}
// api/users/user
public HttpResponseMessage Post([FromUri]User user)
{
}
}
This works as long as you send only one parameter in your HTTP request. When sending multiple, you need to create a custom model which has all your parameters like this:
public class MyModel
{
public string MyProperty { get; set; }
public string MyProperty2 { get; set; }
}
[Route("search")]
[HttpPost]
public async Task<dynamic> Search([FromBody] MyModel model)
{
// model.MyProperty;
// model.MyProperty2;
}
From Microsoft's documentation for parameter binding in ASP.NET Web API:
When a parameter has [FromBody], Web API uses the Content-Type header to select a formatter. In this example, the content type is "application/json" and the request body is a raw JSON string (not a JSON object). At most one parameter is allowed to read from the message body.
This should work:
public HttpResponseMessage Post([FromBody] string name) { ... }
This will not work:
// Caution: This won't work! public HttpResponseMessage Post([FromBody] int id, [FromBody] string name) { ... }
The reason for this rule is that the request body might be stored in a non-buffered stream that can only be read once.
Just adding my problem i had:
$this->load->model("planning/plan_model.php");
and the .php
shouldnt be there, so it should have been:
$this->load->model("planning/plan_model");
hope this helps someone
Please Try to pass parameters in httpoptions
, you can follow function below
deleteAction(url, data) {
const authToken = sessionStorage.getItem('authtoken');
const options = {
headers: new HttpHeaders({
'Content-Type': 'application/json',
Authorization: 'Bearer ' + authToken,
}),
body: data,
};
return this.client.delete(url, options);
}
You could do so by using the attribute accept
and adding allowed mime-types to it. But not all browsers do respect that attribute and it could easily be removed via some code inspector. So in either case you need to check the file type on the server side (your second question).
Example:
<input type="file" name="upload" accept="application/pdf,application/vnd.ms-excel" />
To your third question "And when I click the files (PDF/XLS) on webpage it automatically should open.":
You can't achieve that. How a PDF or XLS is opened on the client machine is set by the user.
With Mongo 3.2 and higher just use your connection string as is:
mongo mongodb://username:[email protected]:10011/my_database
Since Django 2.x, on_delete
is required.
Deprecated since version 1.9: on_delete will become a required argument in Django 2.0. In older versions it defaults to CASCADE.
The database user also seems to be case-sensitive, so while I had a root'@'% user I didn't have a ROOT'@'% user. I changed the user to be uppercase via workbench and the problem was resolved!
If you want to be sure to not have to deal with quotes for the syntax stash@{x}
, use Git 2.11 (Q4 2016)
See commit a56c8f5 (24 Oct 2016) by Aaron M Watson (watsona4
).
(Merged by Junio C Hamano -- gitster
-- in commit 9fa1f90, 31 Oct 2016)
stash
: allow stashes to be referenced by index onlyInstead of referencing "
stash@{n}
" explicitly, make it possible to simply reference as "n
".
Most users only reference stashes by their position in the stash stack (what I refer to as the "index" here).The syntax for the typical stash (
stash@{n}
) is slightly annoying and easy to forget, and sometimes difficult to escape properly in a script.Because of this the capability to do things with the stash by simply referencing the index is desirable.
So:
git stash drop 1
git stash pop 1
git stash apply 1
git stash show 1
How is the HashMap declaration expressed in that scope? It should be:
HashMap<String, ArrayList> dictMap
If not, it is assumed to be Objects.
For instance, if your code is:
HashMap dictMap = new HashMap<String, ArrayList>();
...
ArrayList current = dictMap.get(dictCode);
that will not work. Instead you want:
HashMap<String, ArrayList> dictMap = new HashMap<String, Arraylist>();
...
ArrayList current = dictMap.get(dictCode);
The way generics work is that the type information is available to the compiler, but is not available at runtime. This is called type erasure. The implementation of HashMap (or any other generics implementation) is dealing with Object. The type information is there for type safety checks during compile time. See the Generics documentation.
Also note that ArrayList
is also implemented as a generic class, and thus you might want to specify a type there as well. Assuming your ArrayList
contains your class MyClass
, the line above might be:
HashMap<String, ArrayList<MyClass>> dictMap

I know it's late, but I take the original code and change some stuff to control easily the css. So I made a code with the addClass() and the removeClass()
Here the full code : http://jsfiddle.net/e5qaD/4837/
if( bottom_of_window > bottom_of_object ){
$(this).addClass('showme');
}
if( bottom_of_window < bottom_of_object ){
$(this).removeClass('showme');
Apart from what cletus answered with regards to debugging, it is used whenever you output an object, like when you use
System.out.println(myObject);
or
System.out.println("text " + myObject);
Ubuntu uses AppArmor and that is whats preventing you from accessing /data/. Fedora uses selinux and that would prevent this on a RHEL/Fedora/CentOS machine.
To modify AppArmor to allow MySQL to access /data/ do the follow:
sudo gedit /etc/apparmor.d/usr.sbin.mysqld
add this line anywhere in the list of directories:
/data/ rw,
then do a :
sudo /etc/init.d/apparmor restart
Another option is to disable AppArmor for mysql altogether, this is NOT RECOMMENDED:
sudo mv /etc/apparmor.d/usr.sbin.mysqld /etc/apparmor.d/disable/
Don't forget to restart apparmor:
sudo /etc/init.d/apparmor restart
The most important among all the three is how they save the order of the entries.
HashMap
- Does not save the order of the entries.
eg.
public static void main(String[] args){
HashMap<String,Integer> hashMap = new HashMap<>();
hashMap.put("First",1);// First ---> 1 is put first in the map
hashMap.put("Second",2);//Second ---> 2 is put second in the map
hashMap.put("Third",3); // Third--->3 is put third in the map
for(Map.Entry<String,Integer> entry : hashMap.entrySet())
{
System.out.println(entry.getKey()+"--->"+entry.getValue());
}
}
LinkedHashMap
: It save the order in which entries were made. eg:
public static void main(String[] args){
LinkedHashMap<String,Integer> linkedHashMap = new LinkedHashMap<>();
linkedHashMap.put("First",1);// First ---> 1 is put first in the map
linkedHashMap.put("Second",2);//Second ---> 2 is put second in the map
linkedHashMap.put("Third",3); // Third--->3 is put third in the map
for(Map.Entry<String,Integer> entry : linkedHashMap.entrySet())
{
System.out.println(entry.getKey()+"--->"+entry.getValue());
}
}
TreeMap
: It saves the entries in ascending order of the keys. eg:
public static void main(String[] args) throws IOException {
TreeMap<String,Integer> treeMap = new TreeMap<>();
treeMap.put("A",1);// A---> 1 is put first in the map
treeMap.put("C",2);//C---> 2 is put second in the map
treeMap.put("B",3); //B--->3 is put third in the map
for(Map.Entry<String,Integer> entry : treeMap.entrySet())
{
System.out.println(entry.getKey()+"--->"+entry.getValue());
}
}
A var
cannot be set to null
since it needs to be statically typed.
var foo = null;
// compiler goes: "Huh, what's that type of foo?"
However, you can use this construct to work around the issue:
var foo = (string)null;
// compiler goes: "Ah, it's a string. Nice."
I don't know for sure, but from what I heard you can also use dynamic
instead of var
. This does not require static typing.
dynamic foo = null;
foo = "hi";
Also, since it was not clear to me from the question if you meant the var
keyword or variables in general: Only references (to classes) and nullable types can be set to null. For instance, you can do this:
string s = null; // reference
SomeClass c = null; // reference
int? i = null; // nullable
But you cannot do this:
int i = null; // integers cannot contain null
If you use RGBA for modern browsers you don't need let older IEs use only the non-transparent version of the given color with RGB.
If you don't stick to CSS-only solutions, give CSS3PIE a try. With this syntax you can see exactly the same result in older IEs that you see in modern browsers:
div {
-pie-background: rgba(223,231,233,0.8);
behavior: url(../PIE.htc);
}
string.Substring(0,n); // 0 - start index and n - number of characters
The PrimeFaces ajax events sometimes are very poorly documented, so in most cases you must go to the source code and check yourself.
p:selectOneMenu
supports change event:
<p:selectOneMenu ..>
<p:ajax event="change" update="msgtext"
listener="#{post.subjectSelectionChanged}" />
<!--...-->
</p:selectOneMenu>
which triggers listener with AjaxBehaviorEvent
as argument in signature:
public void subjectSelectionChanged(final AjaxBehaviorEvent event) {...}
You need to escape them by doubling them (verbatim string literal):
string str = @"""How to add doublequotes""";
Or with a normal string literal you escape them with a \
:
string str = "\"How to add doublequotes\"";
You have to put your script tag after the one that references Angular. Move it out of the head
:
<script type="text/javascript" src="angular.min.js"></script>
<script type="text/javascript" src="main.js"></script>
The way you've set it up now, your script runs before Angular is loaded on the page.
Nullable types did not come in until 2.0.
If nullable types had been made in the beginning of the language then string would have been non-nullable and string? would have been nullable. But they could not do this du to backward compatibility.
A lot of people talk about ref-type or not ref type, but string is an out of the ordinary class and solutions would have been found to make it possible.
File -> Export -> Web -> WAR file
OR in Kepler follow as shown below :
There are different ways to achieve this, but I'm not sure which one is the best (I don't even know is there is a best way). I know at least two different ways to do this in a ListView:
1. Set divider to null:
1.1. Programmatically
yourListView.setDivider(null);
1.2. XML
This goes inside your ListView element.
android:divider="@null"
2. Set divider to transparent and set its height to 0 to avoid adding space between listview elements:
2.1. Programmatically:
yourListView.setDivider(new ColorDrawable(android.R.color.transparent));
yourListView.setDividerHeight(0);
2.2. XML
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
I had the same issue and finally it was resolved by disconnecting from all VPN .
You can use git checkout <file>
to check out the committed version of the file (thus discarding your changes), or git reset --hard HEAD
to throw away any uncommitted changes for all files.
A coworker just mentioned this thread. I've independently implemented hash tables within bash, and it's not dependent on version 4. From a blog post of mine in March 2010 (before some of the answers here...) entitled Hash tables in bash:
I previously used cksum
to hash but have since translated Java's string hashCode to native bash/zsh.
# Here's the hashing function
ht() {
local h=0 i
for (( i=0; i < ${#1}; i++ )); do
let "h=( (h<<5) - h ) + $(printf %d \'${1:$i:1})"
let "h |= h"
done
printf "$h"
}
# Example:
myhash[`ht foo bar`]="a value"
myhash[`ht baz baf`]="b value"
echo ${myhash[`ht baz baf`]} # "b value"
echo ${myhash[@]} # "a value b value" though perhaps reversed
echo ${#myhash[@]} # "2" - there are two values (note, zsh doesn't count right)
It's not bidirectional, and the built-in way is a lot better, but neither should really be used anyway. Bash is for quick one-offs, and such things should quite rarely involve complexity that might require hashes, except perhaps in your ~/.bashrc
and friends.
You can determine if as certain word is found in a cell by using
If InStr(cell.Value, "Word1") > 0 Then
If Word1 is found in the string the InStr()
function will return the location of the first character of Word1 in the string.
You do this via attributes on the properties, like this:
[Description("Test text displayed in the textbox"),Category("Data")]
public string Text {
get => myInnerTextBox.Text;
set => myInnerTextBox.Text = value;
}
The category is the heading under which the property will appear in the Visual Studio Properties box. Here's a more complete MSDN reference, including a list of categories.
Emulator are very hard to create since there are many hacks (as in unusual effects), timing issues, etc that you need to simulate.
For an example of this, see http://queue.acm.org/detail.cfm?id=1755886.
That will also show you why you ‘need’ a multi-GHz CPU for emulating a 1MHz one.
This has already been answered, but I think the simplest syntax is:
CREATE TABLE History (
ID int primary key IDENTITY(1,1) NOT NULL,
. . .
The more complicated constraint index is useful when you actually want to change the options.
By the way, I prefer to name such a column HistoryId, so it matches the names of the columns in foreign key relationships.
I had the same error using an UpdateView
I had this:
if form.is_valid() and form2.is_valid():
form.save()
form2.save()
return HttpResponseRedirect(self.get_success_url())
and I solved just doing:
if form.is_valid() and form2.is_valid():
form.save()
form2.save()
return HttpResponseRedirect(reverse_lazy('adopcion:solicitud_listar'))
I had the same error, and for some reason it appears to have been cause by uppercase letters in the Jenkins job that ran the docker run
command.
If you are using a named instance, the port you using likely is 1434, instead of 1433, so please check that out using telnet or netstat aforementioned too.
I got this error when I set ft_min_word_len = 2
in my.cnf
, which lowers the minimum word length in a full text index to 2, from the default of 4.
Repairing the table fixed the problem.

}
Here is one case that caught me out, using a global as a default value of a parameter.
globVar = None # initialize value of global variable
def func(param = globVar): # use globVar as default value for param
print 'param =', param, 'globVar =', globVar # display values
def test():
global globVar
globVar = 42 # change value of global
func()
test()
=========
output: param = None, globVar = 42
I had expected param to have a value of 42. Surprise. Python 2.7 evaluated the value of globVar when it first parsed the function func. Changing the value of globVar did not affect the default value assigned to param. Delaying the evaluation, as in the following, worked as I needed it to.
def func(param = eval('globVar')): # this seems to work
print 'param =', param, 'globVar =', globVar # display values
Or, if you want to be safe,
def func(param = None)):
if param == None:
param = globVar
print 'param =', param, 'globVar =', globVar # display values
Seems like at least 10 questions rolled into one here, a couple points.
Response.Clear - it really depends on what else is going on in the app - if you have httpmodules early in the pipeline that might be writing stuff you don't want - then clear it. Test it and find out. Fiddler or Wireshark useful for this.
Content Type to text/xml - yup - good idea - read up on HTTP spec as to why this is important. IMO anyone doing web work should have read the 1.0 and 1.1 spec at least once.
Encoding - how is your xml encoded - if it is utf-8, then say so, if not, say something else appropriate, just make sure they all match.
Page - personally, would use ashx or httpmodule, if you are using page, and want it a bit faster, get rid of autoeventwireup and bind the event handlers manually.
Would probably be a bit of a waste of memory to dump the xml into a string first, but it depends a lot on the size of the xml as to whether you would ever notice.
As others have suggested, saving the xml to the output stream probably the fastest, I would normally do that, but if you aren't sure, test it, don't rely on what you read on the interweb. Don't just believe anything I say.
For another approach, if the xml doesn't change that much, you could just write it to the disk and serve the file directly, which would likely be quite performant, but like everything in programming, it depends...
but what I got is something like this: Date@124bbbf
while I change the import to: import java.util.Date;
the code works perfectly, why?
What do you mean by "works perfectly"? The output of printing a Date object is the same no matter whether you imported java.util.* or java.util.Date. The output that you get when printing objects is the representation of the object by the toString() method of the corresponding class.
I'm not an expert on MySQL I would suggest you look at REGEXP
.
SELECT * FROM MyTable WHERE ColumnX REGEXP '^[a-z]';
Use this :
#Inputs
L1 = [1, 2]
L2 = [3,4,5]
#Code
L1+L2
#Output
[1, 2, 3, 4, 5]
By using the (+) operator you can skip the multiple append & extend operators in just one line of code and this is valid for more then two of lists by L1+L2+L3+L4.......etc.
Happy Learning...:)
Try
if (!(i == 'InvKey' || i == 'PostDate')) {
or
if (i != 'InvKey' || i != 'PostDate') {
that says if i does not equals InvKey
OR PostDate

UIView.transition(with: mysuperview, duration: 0.75, options:UIViewAnimationOptions.transitionFlipFromRight , animations: {

Using extends you can only get from the collection. You cannot put into it. Also, though super allows to both get and put, the return type during get is ? super T.
For a public action on an OSM map (position a marker on click) the question was: 1) how to determine the duration of mouse down->up (you can't imagine creating a new marker for each click) and 2) did the mouse move during down->up (i.e user is dragging the map).
const map = document.getElementById('map');
map.addEventListener("mousedown", position);
map.addEventListener("mouseup", calculate);
let posX, posY, endX, endY, t1, t2, action;
function position(e) {
posX = e.clientX;
posY = e.clientY;
t1 = Date.now();
}
function calculate(e) {
endX = e.clientX;
endY = e.clientY;
t2 = (Date.now()-t1)/1000;
action = 'inactive';
if( t2 > 0.5 && t2 < 1.5) { // Fixing duration of mouse down->up
if( Math.abs( posX-endX ) < 5 && Math.abs( posY-endY ) < 5 ) { // 5px error on mouse pos while clicking
action = 'active';
// --------> Do something
}
}
console.log('Down = '+posX + ', ' + posY+'\nUp = '+endX + ', ' + endY+ '\nAction = '+ action);

Since Gradle 4.9, the command line arguments can be passed with --args. For example, if you want to launch the application with command line arguments foo --bar
, you can use
gradle run --args='foo --bar'
For Windows Service, you need to run tomcat9w.exe (or 6w/7w/8w) depending on your version of tomcat. First, make sure tomcat is stopped. Then double click on tomcat9w.exe. Navigate to the Java tab. If you know you have 64 bit Windows with 64 bit Java and 64 bit Tomcat, then feel free to set the memory higher than 512. You'll need to do some task manager monitoring to determine how high to set it. For most apps developed in 2019... I'd recommend an initial memory pool of 1024, and the maximum memory pool of 2048. Of course if your computer has tons of RAM... feel free to go as high as you want. Also, see this answer: How to increase Maximum Memory Pool Size? Apache Tomcat 9
For me this has worked-
ALTER TABLE table_name ALTER COLUMN column_name VARCHAR(50)
Redirection of program output is performed by the shell.
grep ... > output.txt
grep
has no mechanism for adding blank lines between each match, but does provide options such as context around the matched line and colorization of the match itself. See the grep(1)
man page for details, specifically the -C
and --color
options.
You can get the ident of the current running thread. The ident could be reused for other threads, if the current thread ends.
When you crate an instance of Thread, a name is given implicit to the thread, which is the pattern: Thread-number
The name has no meaning and the name don't have to be unique. The ident of all running threads is unique.
import threading
def worker():
print(threading.current_thread().name)
print(threading.get_ident())
threading.Thread(target=worker).start()
threading.Thread(target=worker, name='foo').start()
The function threading.current_thread() returns the current running thread. This object holds the whole information of the thread.
invert isBefore method of moment to check if a date is same as today or in future like this:

Seems you are looking for ORDER BY

ending order with LIMIT clause:
SELECT

scores
ORDER BY score DESC
LIMIT 10
Of course SELECT *
could seriously affect performance, so use it with caution.
When you use Integrated Windows Authentication (i.e., Active Directory Single Sign-On), you authenticate to AD resources automatically with your AD credentials. You've are already signed in to AD and these credentials are reused automatically. Therefore if your server is IWA-enabled (e.g., VisualSVN Server), the server does not ask you to enter username and password, passing --username
and --password
does not work, and the SVN client does not cache your credentials on disk, too.
When you want to change the user account that's used to contact the server, you need use the Windows Credential Manager on client side. This is also helpful when your computer is not domain joined and you need to store your AD credentials to access your domain resources.
Follow these steps to save the user's domain credentials to Windows Credential Manager on the user's computer:
svn.example.com
).DOMAIN\Username
format.Now when you will contact https://svn.example.com/svn/MyRepo
or a similar URL, the client or web browser will use the credentials saved in the Credential Manager to authenticate to the server.
If you don't mind using jQuery, then you can use offset()
function. Refer to documentation if you want to read up more about this function.
Adding to the top voted answer and many ones above stressing the "more generic, better", I would like to dig a little bit more.
Map
is the structure contract while HashMap
is an implementation providing its own methods to deal with different real problems: how to calculate index, what is the capacity and how to increment it, how to insert, how to keep the index unique, etc.
Let's look into the source code:
In Map
we have the method of containsKey(Object key)
:
boolean containsKey(Object key);
JavaDoc:
boolean java.util.Map.containsValue(Object value)
Returns true if this map maps one or more keys to the specified value. More formally, returns true if and only if this map contains at least one mapping to a value
v
such that(value==null ? v==null : value.equals(v))
. This operation will probably require time linear in the map size for most implementations of the Map interface.Parameters:value
value whose presence in this map is to betested
Returns:true
if this map maps one or more keys to the specified
valueThrows:
ClassCastException - if the value is of an inappropriate type for this map (optional)
NullPointerException - if the specified value is null and this map does not permit null values (optional)
It requires its implementations to implement it, but the "how to" is at its freedom, only to ensure it returns correct.
In HashMap
:
public boolean containsKey(Object key) {
return getNode(hash(key), key) != null;
}
It turns out that HashMap
uses hashcode to test if this map contains the key. So it has the benefit of hash algorithm.
put:
If I want to update my first
name, then I send a put request:
{ "first": "Nazmul", "last": "hasan" }
But here is a problem with using put
request: When I want to send put
request I have to send all two parameters that is first
and last
(whereas I only need to update first
) so it is mandatory to send them all again with put
request.
patch:
patch
request, on the other hand, says: only specify the data
which you need to update
and it won't be affecting or changing other data.
So no need to send all values again. Do I only need to change first
name? Well, It only suffices to specify first
in patch
request.
I suggest you use Promise
myApp.service('dataService', function($http,$q) {
delete $http.defaults.headers.common['X-Requested-With'];
this.getData = function() {
deferred = $q.defer();
$http({
method: 'GET',
url: 'https://www.example.com/api/v1/page',
params: 'limit=10, sort_by=created:desc',
headers: {'Authorization': 'Token token=xxxxYYYYZzzz'}
}).success(function(data){
// With the data succesfully returned, we can resolve promise and we can access it in controller
deferred.resolve();
}).error(function(){
alert("error");
//let the function caller know the error
deferred.reject(error);
});
return deferred.promise;
}
});
so In your controller you can use the method
myApp.controller('AngularJSCtrl', function($scope, dataService) {
$scope.data = null;
dataService.getData().then(function(response) {
$scope.data = response;
});
});
promises are powerful feature of angularjs and it is convenient special if you want to avoid nesting callbacks.
For PHPStorm 2020.3.2 on ubuntu inorder to reset expiration license, you should run following commands:
sudo rm ~/.config/JetBrains/PhpStorm2020.3/options/other.xml
sudo rm ~/.config/JetBrains/PhpStorm2020.3/eval/*
sudo rm -rf .java/.userPrefs
Basically you need the FolderBrowserDialog
class:
Prompts the user to select a folder. This class cannot be inherited.
Example:
using(var fbd = new FolderBrowserDialog())
{
DialogResult result = fbd.ShowDialog();
if (result == DialogResult.OK && !string.IsNullOrWhiteSpace(fbd.SelectedPath))
{
string[] files = Directory.GetFiles(fbd.SelectedPath);
System.Windows.Forms.MessageBox.Show("Files found: " + files.Length.ToString(), "Message");
}
}
If you work in WPF you have to add the reference to System.Windows.Forms
.
you also have to add using System.IO
for Directory
class
Make sure you own root directory for npm so you don't get any errors when you install global packages without using sudo.
procedures:- in root directory
sudo chown -R yourUsername /usr/local/lib/node_modules
sudo chown -R yourUsername /usr/local/bin/
sudo chown -R yourUsername /usr/local/share/
So now with
npm i npm -g
you get no errors and no use of sudo here. but if you still get errors confirm node_modules is owned again
/usr/local/lib/
and make sure you own everything
ls -la
npm i -g nodemon
will work!
Using an iframe
to "render" a PDF will not work on all browsers; it depends on how the browser handles PDF files. Some browsers (such as Firefox and Chrome) have a built-in PDF rendered which allows them to display the PDF inline where as some older browsers (perhaps older versions of IE attempt to download the file instead).
Instead, I recommend checking out PDFObject which is a Javascript library to embed PDFs in HTML files. It handles browser compatibility pretty well and will most likely work on IE8.
In your HTML, you could set up a div
to display the PDFs:
<div id="pdfRenderer"></div>
Then, you can have Javascript code to embed a PDF in that div
:
var pdf = new PDFObject({
url: "https://something.com/HTC_One_XL_User_Guide.pdf",
id: "pdfRendered",
pdfOpenParams: {
view: "FitH"
}
}).embed("pdfRenderer");
In VB2008, it works this way:
Project>Add References
Then click on the Recent tab where you can see list of references used recently. Locate the one you do not want and delet it. Then you close without adding anything.
numline = len(file_read.readlines())
It doesn't work because it's not supported
The
DEFAULT
clause specifies a default value for a column. With one exception, the default value must be a constant; it cannot be a function or an expression. This means, for example, that you cannot set the default for a date column to be the value of a function such asNOW()
orCURRENT_DATE
. The exception is that you can specifyCURRENT_TIMESTAMP
as the default for aTIMESTAMP
column
0 values of basic types (1)(2)map to false
.
Other values map to true
.
This convention was established in original C, via its flow control statements; C didn't have a boolean type at the time.
It's a common error to assume that as function return values, false
indicates failure. But in particular from main
it's false
that indicates success. I've seen this done wrong many times, including in the Windows starter code for the D language (when you have folks like Walter Bright and Andrei Alexandrescu getting it wrong, then it's just dang easy to get wrong), hence this heads-up beware beware.
There's no need to cast to bool
for built-in types because that conversion is implicit. However, Visual C++ (Microsoft's C++ compiler) has a tendency to issue a performance warning (!) for this, a pure silly-warning. A cast doesn't suffice to shut it up, but a conversion via double negation, i.e. return !!x
, works nicely. One can read !!
as a “convert to bool
” operator, much as -->
can be read as “goes to”. For those who are deeply into readability of operator notation. ;-)
1) C++14 §4.12/1 “A zero value, null pointer value, or null member pointer value is converted to false
; any other value is converted to true
. For direct-initialization (8.5), a prvalue of type std::nullptr_t
can be converted to a prvalue of type bool
; the resulting value is false
.”
2) C99 and C11 §6.3.1.2/1 “When any scalar value is converted to _Bool
, the result is 0 if the value compares equal to 0; otherwise, the result is 1.”
A simpler way is
ggplot(data=df, aes(x=xvar, y=yvar)) +
geom_point()
ggsave(path = path, width = width, height = height, device='tiff', dpi=700)
See here: Physical Vs Virtual Memory
Virtual memory is stored on the hard drive and is used when the RAM is filled. Physical memory is limited to the size of the RAM chips installed in the computer. Virtual memory is limited by the size of the hard drive, so virtual memory has the capability for more storage.

Scripting for the Java Platform « Run Javascript on the JVM with Rhino/Nashorn
Rhino « Rhino is an open-source implementation of JavaScript written entirely in Java. It is typically embedded into Java applications to provide scripting to end users. It is embedded in J2SE 6 as the default Java scripting engine.
Nashorn is a JavaScript engine developed in the Java programming language by Oracle. It is based on the Da Vinci Machine and has been released with Java 8.

I wrote a little script to manage cloning a new repo and making local branches for all the remote branches.
You can find the latest version here:
#!/bin/bash
# Clones as usual but creates local tracking branches for all remote branches.
# To use, copy this file into the same directory your git binaries are (git, git-flow, git-subtree, etc)
clone_output=$((git clone "$@" ) 2>&1)
retval=$?
echo $clone_output
if [[ $retval != 0 ]] ; then
exit 1
fi
pushd $(echo $clone_output | head -1 | sed 's/Cloning into .\(.*\).\.\.\./\1/') > /dev/null 2>&1
this_branch=$(git branch | sed 's/^..//')
for i in $(git branch -r | grep -v HEAD); do
branch=$(echo $i | perl -pe 's/^.*?\///')
# this doesn't have to be done for each branch, but that's how I did it.
remote=$(echo $i | sed 's/\/.*//')
if [[ "$this_branch" != "$branch" ]]; then
git branch -t $branch $remote/$branch
fi
done
popd > /dev/null 2>&1
To use it, just copy it into your git bin directory (for me, that’s C:\Program Files (x86)\Git\bin\git-cloneall
), then, on the command line:
git cloneall [standard-clone-options] <url>
It clones as usual, but creates local tracking branches for all remote branches.
We can use Angular event bindings to respond to any DOM event. The syntax is simple. We surround the DOM event name in parentheses and assign a quoted template statement to it. -- reference
Since change
is on the list of standard DOM events, we can use it:
(change)="saverange()"
In your particular case, since you're using NgModel, you could break up the two-way binding like this instead:
[ngModel]="range" (ngModelChange)="saverange($event)"
Then
saverange(newValue) {
this.range = newValue;
this.Platform.ready().then(() => {
this.rootRef.child("users").child(this.UserID).child('range').set(this.range)
})
}
However, with this approach saverange()
is called with every keystroke, so you're probably better off using (change)
.

If you have to convert dates other than today to different timezones you have to deal with daylight savings. I wanted a solution that could be done without worrying about database version, without using stored functions and something that could easily be ported to Oracle.
I think Warren is on the right track with getting the correct dates for daylight time, but to make it more useful for multiple time zone and different rules for countries and even the rule that changed in the US between 2006 and 2007, here a variation on the above solution. Notice that this not only has us time zones, but also central Europe. Central Europe follow the last sunday of april and last sunday of october. You will also notice that the US in 2006 follows the old first sunday in april, last sunday in october rule.
This SQL code may look a little ugly, but just copy and paste it into SQL Server and try it. Notice there are 3 section for years, timezones and rules. If you want another year, just add it to the year union. Same for another time zone or rule.

There are two ways to go about doing this.
Create a state in the constructor that contains the text input. Attach an onChange event to the input box that updates state each time. Then onClick you could just alert the state object.
handleClick: function() { alert(this.refs.myInput.value); },
Building off of Mamboking's answer:
ContractsDao mock_contractsDao = mock(ContractsDao.class);
when(mock_contractsDao.save(anyString())).thenReturn("Some result");
m_orderSvc.m_contractsDao = mock_contractsDao;
m_prog = new ProcessOrdersWorker(m_orderSvc, m_opportunitySvc, m_myprojectOrgSvc);
m_prog.work();
Addressing your request to verify whether the argument contains a certain value, I could assume you mean that the argument is a String and you want to test whether the String argument contains a substring. For this you could do:
ArgumentCaptor<String> savedCaptor = ArgumentCaptor.forClass(String.class);
verify(mock_contractsDao).save(savedCaptor.capture());
assertTrue(savedCaptor.getValue().contains("substring I want to find");
If that assumption was wrong, and the argument to save()
is a collection of some kind, it would be only slightly different:
ArgumentCaptor<Collection<MyType>> savedCaptor = ArgumentCaptor.forClass(Collection.class);
verify(mock_contractsDao).save(savedCaptor.capture());
assertTrue(savedCaptor.getValue().contains(someMyTypeElementToFindInCollection);
You might also check into ArgumentMatchers, if you know how to use Hamcrest matchers.
You can use display: block
Example :
<!DOCTYPE html>
<html>
<body>
<p id="demo">Lorem Ipsum</p>
<button type="button"
onclick="document.getElementById('demo').style.display='none'">Click Me!</button>
<button type="button"
onclick="document.getElementById('demo').style.display='block'">Click Me!</button>

If you install TFS 2008 PowerTools you will get a "Find in Source Control" action in the Team Explorer right click menu.
There are now safer methods to accomplish this. The docs have been updated with these methods.
Other Methods
Easiest - Use Unicode, save the file as UTF-8 and set the charset
to UTF-8.
<div>{'First · Second'}</div>
Safer - Use the Unicode number for the entity inside a Javascript string.
<div>{'First \u00b7 Second'}</div>
or
<div>{'First ' + String.fromCharCode(183) + ' Second'}</div>
Or a mixed array with strings and JSX elements.
<div>{['First ', <span>·</span>, ' Second']}</div>
Last Resort - Insert raw HTML using dangerouslySetInnerHTML
.
<div dangerouslySetInnerHTML={{__html: 'First · Second'}} />

Looking at the answers and the question, it seems the question has been modified significantly. So to answer the current question:
Convert LocalDateTime to LocalDateTime in UTC.
LocalDateTime
does not store any information about the time-zone, it just basically holds the values of year, month, day, hour, minute, second, and smaller units. So an important question is: What is the timezone of the original LocalDateTime
? It might as well be UTC already, therefore no conversion has to be made.
Considering that you asked the question anyway, you probably meant that the original time is in your system-default timezone and you want to convert it to UTC. Because usually a LocalDateTime
object is created by using LocalDateTime.now()
which returns the current time in the system-default timezone. In this case, the conversion would be the following:
LocalDateTime convertToUtc(LocalDateTime time) {
return time.atZone(ZoneId.systemDefault()).withZoneSameInstant(ZoneOffset.UTC).toLocalDateTime();
}
An example of the conversion process:
2019-02-25 11:39 // [time] original LocalDateTime without a timezone
2019-02-25 11:39 GMT+1 // [atZone] converted to ZonedDateTime (system timezone is Madrid)
2019-02-25 10:39 GMT // [withZoneSameInstant] converted to UTC, still as ZonedDateTime
2019-02-25 10:39 // [toLocalDateTime] losing the timezone information
In any other case, when you explicitly specify the timezone of the time to convert, the conversion would be the following:
LocalDateTime convertToUtc(LocalDateTime time, ZoneId zone) {
return time.atZone(zone).withZoneSameInstant(ZoneOffset.UTC).toLocalDateTime();
}
An example of the conversion process:
2019-02-25 11:39 // [time] original LocalDateTime without a timezone
2019-02-25 11:39 GMT+2 // [atZone] converted to ZonedDateTime (zone is Europe/Tallinn)
2019-02-25 09:39 GMT // [withZoneSameInstant] converted to UTC, still as ZonedDateTime
2019-02-25 09:39 // [toLocalDateTime] losing the timezone information
atZone()
MethodThe result of the atZone()
method depends on the time passed as its argument, because it considers all the rules of the timezone, including Daylight Saving Time (DST). In the examples, the time was 25th February, in Europe this means winter time (no DST).
If we were to use a different date, let's say 25th August from last year, the result would be different, considering DST:
2018-08-25 11:39 // [time] original LocalDateTime without a timezone
2018-08-25 11:39 GMT+3 // [atZone] converted to ZonedDateTime (zone is Europe/Tallinn)
2018-08-25 08:39 GMT // [withZoneSameInstant] converted to UTC, still as ZonedDateTime
2018-08-25 08:39 // [toLocalDateTime] losing the timezone information
The GMT time does not change. Therefore the offsets in the other timezones are adjusted. In this example, the summer time of Estonia is GMT+3, and winter time GMT+2.
Also, if you specify a time within the transition of changing clocks back one hour. E.g. October 28th, 2018 03:30 for Estonia, this can mean two different times:
2018-10-28 03:30 GMT+3 // summer time [UTC 2018-10-28 00:30]
2018-10-28 04:00 GMT+3 // clocks are turned back 1 hour [UTC 2018-10-28 01:00]
2018-10-28 03:00 GMT+2 // same as above [UTC 2018-10-28 01:00]
2018-10-28 03:30 GMT+2 // winter time [UTC 2018-10-28 01:30]
Without specifying the offset manually (GMT+2 or GMT+3), the time 03:30
for the timezone Europe/Tallinn
can mean two different UTC times, and two different offsets.
As you can see, the end result depends on the timezone of the time passed as an argument. Because the timezone cannot be extracted from the LocalDateTime
object, you have to know yourself which timezone it is coming from in order to convert it to UTC.
Antonio's answer
CONCAT(REPLACE(FORMAT(number,0),',','.'),',',SUBSTRING_INDEX(FORMAT(number,2),'.',-1))
is wrong; it may produce incorrect results!
For example, if "number" is 12345.67, the resulting string would be:
'12.346,67'
instead of
'12.345,67'
because FORMAT(number,0) rounds "number" up if fractional part is greater or equal than 0.5 (as it is in my example)!
What you COULD use is
CONCAT(REPLACE(FORMAT(FLOOR(number),0),',','.'),',',SUBSTRING_INDEX(FORMAT(number,2),'.',-1))
if your MySQL/MariaDB's FORMAT doesn't support "locale_name" (see MindStalker's post - Thx 4 that, pal). Note the FLOOR function I've added.
Here is another method, much simple, lets say your dataframe name is daat
and column name is YEARMONTH
daat.YEARMONTH.value_counts()
The first thing you need to study is the java.util.Set
API.
Here's a small example of how to use its methods:
Set<Integer> numbers = new TreeSet<Integer>();
numbers.add(2);
numbers.add(5);
System.out.println(numbers); // "[2, 5]"
System.out.println(numbers.contains(7)); // "false"
System.out.println(numbers.add(5)); // "false"
System.out.println(numbers.size()); // "2"
int sum = 0;
for (int n : numbers) {
sum += n;
}
System.out.println("Sum = " + sum); // "Sum = 7"
numbers.addAll(Arrays.asList(1,2,3,4,5));
System.out.println(numbers); // "[1, 2, 3, 4, 5]"
numbers.removeAll(Arrays.asList(4,5,6,7));
System.out.println(numbers); // "[1, 2, 3]"
numbers.retainAll(Arrays.asList(2,3,4,5));
System.out.println(numbers); // "[2, 3]"
Once you're familiar with the API, you can use it to contain more interesting objects. If you haven't familiarized yourself with the equals
and hashCode
contract, already, now is a good time to start.
In a nutshell:
@Override
both or none; never just one. (very important, because it must satisfied property: a.equals(b) == true --> a.hashCode() == b.hashCode()
boolean equals(Thing other)
instead; this is not a proper @Override
.x, y, z
, equals
must be:
x.equals(x)
.x.equals(y)
if and only if y.equals(x)
x.equals(y) && y.equals(z)
, then x.equals(z)
x.equals(y)
must not change unless the objects have mutatedx.equals(null) == false
hashCode
is:
equals
: if x.equals(y)
, then x.hashCode() == y.hashCode()
equals
and hashCode
.Next, you may want to impose an ordering of your objects. You can do this by making your type implements Comparable
, or by providing a separate Comparator
.
Having either makes it easy to sort your objects (Arrays.sort
, Collections.sort(List)
). It also allows you to use SortedSet
, such as TreeSet
.

The statement SELECT 1 FROM SomeTable
just returns a column containing the value 1
for each row in your table. If you add another column in, e.g. SELECT 1, cust_name FROM SomeTable
then it makes it a little clearer:
cust_name
----------- ---------------
1 Village Toys
1 Kids Place
1 Fun4All
1 Fun4All
1 The Toy Store
Just return (number % 10)
; i.e. take the modulus. This will be much faster than parsing in and out of a string.
If number
can be negative then use (Math.abs(number) % 10);

Looks like the change()
function is only called when you check a radio button, not when you uncheck it. The solution I used is to bind the change event to every radio button:
$("#r1, #r2, #r3").change(function () {
Or you could give all the radio buttons the same name:
$("input[name=someRadioGroup]:radio").change(function () {

You can check Announcing the official release of the Visual C++ Build Tools 2015 and from this blog, we can know that the Build Tools are the same C++ tools that you get with Visual Studio 2015 but they come in a scriptable standalone installer that only lays down the tools you need to build C++ projects. The Build Tools give you a way to install the tools you need on your build machines without the IDE you don’t need.
Because these components are the same as the ones installed by the Visual Studio 2015 Update 2 setup, you cannot install the Visual C++ Build Tools on a machine that already has Visual Studio 2015 installed. Therefore, it asks you to uninstall your existing VS 2015 when you tried to install the Visual C++ build tools using the standalone installer. Since you already have the VS 2015, you can go to Control Panel—Programs and Features and right click the VS 2015 item and Change-Modify, then check the option of those components that relates to the Visual C++ Build Tools, like Visual C++, Windows SDK… then install them. After the installation is successful, you can build the C++ projects.

I assume with the second line you actually mean:
Thing *thing = new Thing("uiae");
which would be the standard way of creating new dynamic objects (necessary for dynamic binding and polymorphism) and storing their address to a pointer. Your code does what JaredPar described, namely creating two objects (one passed a const char*
, the other passed a const Thing&
), and then calling the destructor (~Thing()
) on the first object (the const char*
one).
By contrast, this:
Thing thing("uiae");
creates a static object which is destroyed automatically upon exiting the current scope.
Here is a quick way to do it in 2021 using the Anaconda Navigator. This is the most reliable way to do it, unless you want to create environments programmatically which I don't think is the case for most users:
There are still a few minor bugs when setting up your environment, most of them should be solved by restarting the Navigator.
If you find a bug, please help us posting it in the Anaconda Issues bug-tracker too! If you run into trouble creating the environment or if the environment was not correctly created you can double check what got installed: Clicking the "Environments" opens a management window showing installed packages. Search and select Spyder-related packages and then click on "Apply" to install them.
The limitation relates to the simplified CommonJS syntax vs. the normal callback syntax:
Loading a module is inherently an asynchronous process due to the unknown timing of downloading it. However, RequireJS in emulation of the server-side CommonJS spec tries to give you a simplified syntax. When you do something like this:
var foomodule = require('foo');
// do something with fooModule
What's happening behind the scenes is that RequireJS is looking at the body of your function code and parsing out that you need 'foo' and loading it prior to your function execution. However, when a variable or anything other than a simple string, such as your example...
var module = require(path); // Call RequireJS require
...then Require is unable to parse this out and automatically convert it. The solution is to convert to the callback syntax;
var moduleName = 'foo';
require([moduleName], function(fooModule){
// do something with fooModule
})
Given the above, here is one possible rewrite of your 2nd example to use the standard syntax:
define(['dyn_modules'], function (dynModules) {
require(dynModules, function(){
// use arguments since you don't know how many modules you're getting in the callback
for (var i = 0; i < arguments.length; i++){
var mymodule = arguments[i];
// do something with mymodule...
}
});
});
EDIT: From your own answer, I see you're using underscore/lodash, so using _.values
and _.object
can simplify the looping through arguments array as above.
I realise this is very old, but it was among the first hits on Google when I was looking for a solution to something similar, so I'll post what I did here. My scenario is slightly different as I basically just wanted to fully explode a jar, along with all jars contained within it, so I wrote the following bash functions:
function explode {
local target="$1"
echo "Exploding $target."
if [ -f "$target" ] ; then
explodeFile "$target"
elif [ -d "$target" ] ; then
while [ "$(find "$target" -type f -regextype posix-egrep -iregex ".*\.(zip|jar|ear|war|sar)")" != "" ] ; do
find "$target" -type f -regextype posix-egrep -iregex ".*\.(zip|jar|ear|war|sar)" -exec bash -c 'source "<file-where-this-function-is-stored>" ; explode "{}"' \;
done
else
echo "Could not find $target."
fi
}
function explodeFile {
local target="$1"
echo "Exploding file $target."
mv "$target" "$target.tmp"
unzip -q "$target.tmp" -d "$target"
rm "$target.tmp"
}
Note the <file-where-this-function-is-stored>
which is needed if you're storing this in a file that is not read for a non-interactive shell as I happened to be. If you're storing the functions in a file loaded on non-interactive shells (e.g., .bashrc
I believe) you can drop the whole source
statement. Hopefully this will help someone.
A little warning - explodeFile
also deletes the ziped file, you can of course change that by commenting out the last line.

For the benefit of searchers, I liked Jakub g's answer, but wanted a little error handling. Obviously it's best to handle errors properly, but this should help prevent a site stopping if an error occurs. Code below:

var express = require('express');
process.on('uncaughtException', function(err) {
console.log(err);
});
var server = express();
server.use(express.static(__dirname));
var port = 10001;
server.listen(port, function() {
console.log('listening on port ' + port);
//var err = new Error('This error won't break the application...')
//throw err
});

Because "append" existed long before "pop" was thought of. Python 0.9.1 supported list.append in early 1991. By comparison, here's part of a discussion on comp.lang.python about adding pop in 1997. Guido wrote:
To implement a stack, one would need to add a list.pop() primitive (and no, I'm not against this particular one on the basis of any principle). list.push() could be added for symmetry with list.pop() but I'm not a big fan of multiple names for the same operation -- sooner or later you're going to read code that uses the other one, so you need to learn both, which is more cognitive load.
You can also see he discusses the idea of if push/pop/put/pull should be at element [0] or after element [-1] where he posts a reference to Icon's list:
I stil think that all this is best left out of the list object implementation -- if you need a stack, or a queue, with particular semantics, write a little class that uses a lists
In other words, for stacks implemented directly as Python lists, which already supports fast append(), and del list[-1], it makes sense that list.pop() work by default on the last element. Even if other languages do it differently.
Implicit here is that most people need to append to a list, but many fewer have occasion to treat lists as stacks, which is why list.append came in so much earlier.

You need to do it in two steps:
CREATE USER 'readonly_user'@'localhost' IDENTIFIED BY 'some_strong_password';
GRANT SELECT, SHOW VIEW ON *.* TO 'readonly_user'@'localhost';
flush privileges;
You should append to the container, not the last element:
$("#content ul").append('<li><a href="/user/messages"><span class="tab">Message Center</span></a></li>');
The append() function should've probably been called add() in jQuery because it sometimes confuses people. You would think it appends something after the given element, while it actually adds it to the element.
Assume we create a shell script named test_args.sh
as follow
#!/bin/sh
until [ $# -eq 0 ]
do
name=${1:1}; shift;
if [[ -z "$1" || $1 == -* ]] ; then eval "export $name=true"; else eval "export $name=$1"; shift; fi
done
echo "year=$year month=$month day=$day flag=$flag"
After we run the following command:
sh test_args.sh -year 2017 -flag -month 12 -day 22
The output would be:
year=2017 month=12 day=22 flag=true
In case anyone is trying to apply the above solutions to a .scatter() instead of a .subplot(),
I tried running the following code
y = [2.56422, 3.77284, 3.52623, 3.51468, 3.02199]
z = [0.15, 0.3, 0.45, 0.6, 0.75]
n = [58, 651, 393, 203, 123]
fig, ax = plt.scatter(z, y)
for i, txt in enumerate(n):
ax.annotate(txt, (z[i], y[i]))
But ran into errors stating "cannot unpack non-iterable PathCollection object", with the error specifically pointing at codeline fig, ax = plt.scatter(z, y)
I eventually solved the error using the following code
plt.scatter(z, y)
for i, txt in enumerate(n):
plt.annotate(txt, (z[i], y[i]))
I didn't expect there to be a difference between .scatter() and .subplot() I should have known better.
In VB.Net. Do NOT use "IsNot Nothing" when you can use ".HasValue". I just solved an "Operation could destabilize the runtime" Medium trust error by replacing "IsNot Nothing" with ".HasValue" In one spot. I don't really understand why, but something is happening differently in the compiler. I would assume that "!= null" in C# may have the same issue.
