In my case for avoiding that problem:
Be sure that you are dealing with Xcode 7, NOT lower versions. In lower version this flag does not exist.
Setup: Project>Build Settings>All>Build Options>Enable Bitcode = NO
If you really need "spring-boot-starter-data-jpa" as your project dependency and at the same time you don't want to allow your app to access any database, you can simply exclude auto-configuration classes
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
You should use
=COUNTIF(A2:A51, "*iPad*")/COUNTA(A2:A51)
Additionally, if you wanted to count more than one element, like iPads OR Kindles, you would use
=SUM(COUNTIF(A2:A51, {"*iPad*", "*kindle*"}))/COUNTA(A2:A51)
in the numerator.
We can also use this with the $_GET
method
$employee_id = 'EMP-1234';
header('Location: employee.php?id='.$employee_id);
I tested bits and pieces of the following, but not the complete rule set in its entirety, so if you run into trouble with it let me know and I'll dig around a bit more. However, assuming I got everything correct, you could try something like the following:
RewriteEngine On
# Check if this is the noredirect query string
RewriteCond %{QUERY_STRING} (^|&)noredirect=true(&|$)
# Set a cookie, and skip the next rule
RewriteRule ^ - [CO=mredir:0:%{HTTP_HOST},S]
# Check if this looks like a mobile device
# (You could add another [OR] to the second one and add in what you
# had to check, but I believe most mobile devices should send at
# least one of these headers)
RewriteCond %{HTTP:x-wap-profile} !^$ [OR]
RewriteCond %{HTTP:Profile} !^$
# Check if we're not already on the mobile site
RewriteCond %{HTTP_HOST} !^m\.
# Check to make sure we haven't set the cookie before
RewriteCond %{HTTP:Cookie} !\smredir=0(;|$)
# Now redirect to the mobile site
RewriteRule ^ http://m.example.org%{REQUEST_URI} [R,L]
To solve this either you down-grade the Django
to any version lesser than 2.0.
pip
install Django==1.11.29
.
The pass
command is what you are looking for. Use pass
for any construct that you want to "ignore". Your example uses a conditional expression but you can do the same for almost anything.
For your specific use case, perhaps you'd want to test the opposite condition and only perform an action if the condition is false:
if num2 != num5:
make_some_changes()
This will be the same as this:
if num2 == num5:
pass
else:
make_some_changes()
That way you won't even have to use pass
and you'll also be closer to adhering to the "Flatter is better than nested" convention in PEP20.
You can read more about the pass
statement in the documentation:
The pass statement does nothing. It can be used when a statement is required syntactically but the program requires no action.
if condition:
pass
try:
make_some_changes()
except Exception:
pass # do nothing
class Foo():
pass # an empty class definition
def bar():
pass # an empty function definition
get_curr_date () {
# get unix time
DATE=$(date +%s)
echo "DATE_CURR : "$DATE
}
conv_utime_hread () {
# convert unix time to human readable format
DATE_HREAD=$(date -d @$DATE +%Y%m%d_%H%M%S)
echo "DATE_HREAD : "$DATE_HREAD
}
There is a way this can be done, but it needs to be planned carefully. Take for example the following QBASIC program:
1 A = 1; B = 10;
10 print "A = ",A;
20 IF (A < B) THEN A = A + 1; GOTO 10
30 PRINT "That's the end."
Then create your JavaScript to initialize all variables first, followed by making an initial function call to start the ball rolling (we execute this initial function call at the end), and set up functions for every set of lines that you know will be executed in the one unit.
Follow this with the initial function call...
var a, b;
function fa(){
a = 1;
b = 10;
fb();
}
function fb(){
document.write("a = "+ a + "<br>");
fc();
}
function fc(){
if(a<b){
a++;
fb();
return;
}
else
{
document.write("That's the end.<br>");
}
}
fa();
The result in this instance is:
a = 1
a = 2
a = 3
a = 4
a = 5
a = 6
a = 7
a = 8
a = 9
a = 10
That's the end.
file = request.FILES['filename']
file.name # Gives name
file.content_type # Gives Content type text/html etc
file.size # Gives file's size in byte
file.read() # Reads file
There is a mistake in your insert statement chage it to below and try :
String sql = "insert into table_name values ('" + Col1 +"','" + Col2 + "','" + Col3 + "')";
We use Liquid XML Studio, it provides a intuitive editable representation of an XSD schema. It also shows the annotations inline, which we find very useful and the split code/gfx view is invaluable when writting or editing an XSD.
find . -type d -print0 | xargs -0 -n 1 my_command
Extending the Throwable class will give you the String property error.stackTraceString
:
val Throwable.stackTraceString: String
get() {
val sw = StringWriter()
val pw = PrintWriter(sw)
this.printStackTrace(pw)
return sw.toString()
}
simplify the whole thing a bit, fix some issues with commas which will blow up some browsers:
$(document).ready(function () {
$("#register").validate({
debug: true,
rules: {
year: {
required: function () {
return ($("#year option:selected").val() == "0");
}
}
},
messages: {
year: "Year Required"
}
});
});
Jumping to an assumption, should your select not have this attribute validate="required:true"
?
It is a common misconception that time (a measurable 4th dimension) is different over the world. Timestamp as a moment in time is unique. Date however is influenced how we "see" time but actually it is "time of day".
An example: two people look at the clock at the same moment. The timestamp is the same, right? But one of them is in London and sees 12:00 noon (GMT, timezone offset is 0), and the other is in Belgrade and sees 14:00 (CET, Central Europe, daylight saving now, offset is +2).
Their perception is different but the moment is the same.
You can find more details in this answer.
OK, it's not a duplicate of this question but it is pointless since you are confusing the terms "Timestamp = moment in time (objective)" and "Date[Time] = time of day (subjective)".
Let's look at your original question code broken down like this:
// Get the "original" value from database.
Timestamp momentFromDB = rs.getTimestamp("anytimestampcolumn");
// Turn it into a Joda DateTime with time zone.
DateTime dt = new DateTime(momentFromDB, DateTimeZone.forID("anytimezone"));
// And then turn it back into a timestamp but "with time zone".
Timestamp ts = new Timestamp(dt.getMillis());
I haven't run this code but I am certain it will print true
and the same number of milliseconds each time:
System.out.println("momentFromDB == dt : " + (momentFromDB.getTime() == dt.getTimeInMillis());
System.out.println("momentFromDB == ts : " + (momentFromDB.getTime() == ts.getTime()));
System.out.println("dt == ts : " + (dt.getTimeInMillis() == ts.getTime()));
System.out.println("momentFromDB [ms] : " + momentFromDB.getTime());
System.out.println("ts [ms] : " + ts.getTime());
System.out.println("dt [ms] : " + dt.getTimeInMillis());
But as you said yourself printing them out as strings will result in "different" time because DateTime
applies the time zone. That's why "time" is stored and transferred as Timestamp
objects (which basically wraps a long
) and displayed or entered as Date[Time]
.
In your own answer you are artificially adding an offset and creating a "wrong" time.
If you use that timestamp to create another DateTime
and print it out it will be offset twice.
// Turn it back into a Joda DateTime with time zone.
DateTime dt = new DateTime(ts, DateTimeZone.forID("anytimezone"));
P.S. If you have the time go through the very complex Joda Time source code to see how it holds the time (millis) and how it prints it.

I think you are not configured properly,
if you are using XAMPP then you can easily send mail from localhost.
for example you can configure C:\xampp\php\php.ini
and c:\xampp\sendmail\sendmail.ini
for gmail to send mail.
in C:\xampp\php\php.ini
find extension=php_openssl.dll
and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.
in php.ini file find [mail function]
and change
SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"
(use the above send mail path only and it will work)
Now Open C:\xampp\sendmail\sendmail.ini
. Replace all the existing code in sendmail.ini with following code
[sendmail]
smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]
Now you have done!! create php file with mail function and send mail from localhost.
Update
First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()
).
You can set the following settings in your PHP.ini:
ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

My bundle script called git-backup
looks like this
#!/usr/bin/env ruby
if __FILE__ == $0
bundle_name = ARGV[0] if (ARGV[0])
bundle_name = `pwd`.split('/').last.chomp if bundle_name.nil?
bundle_name += ".git.bundle"
puts "Backing up to bundle #{bundle_name}"
`git bundle create /data/Dropbox/backup/git-repos/#{bundle_name} --all`
end
Sometimes I use git backup
and sometimes I use git backup different-name
which gives me most of the possibilities I need.
For me the following solution worked Unable to stop MySQL on OS X 10.10
To stop the auto start I used:
sudo launchctl unload -w /Library/LaunchDaemons/com.mysql.mysql.plist
And to kill the service I used:
sudo pkill mysqld
Try to edit your my.cf and comment the original sql_mode and add sql_mode = "".
vi /etc/mysql/my.cnf
sql_mode = ""
save and quit...
service mysql restart
SimpleDateFormat
is a concrete class for formatting and parsing dates in a locale-sensitive manner.
From the JavaDoc
,
But Date formats are not synchronized. It is recommended to create separate format instances for each thread. If multiple threads access a format concurrently,
it must be synchronized externally
.
To make the SimpleDateFormat class thread-safe, look at the following approaches :
A couple of "enhancements" I use for debugging, especially when running projects (ie not in debug mode).
Automatically copy the caller-name and message to the clipboard, because you can't search an image!
package forumposts;
import java.awt.Toolkit;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.StringSelection;
import javax.swing.JOptionPane;
public final class MsgBox
{
public static void info(String message) {
info(message, theNameOfTheMethodThatCalledMe());
}
public static void info(String message, String caller) {
show(message, caller, JOptionPane.INFORMATION_MESSAGE);
}
static void error(String message) {
error(message, theNameOfTheMethodThatCalledMe());
}
public static void error(String message, String caller) {
show(message, caller, JOptionPane.ERROR_MESSAGE);
}
public static void show(String message, String title, int iconId) {
setClipboard(title+":"+NEW_LINE+message);
JOptionPane.showMessageDialog(null, message, title, iconId);
}
private static final String NEW_LINE = System.lineSeparator();
public static String theNameOfTheMethodThatCalledMe() {
return Thread.currentThread().getStackTrace()[3].getMethodName();
}
public static void setClipboard(String message) {
CLIPBOARD.setContents(new StringSelection(message), null);
// nb: we don't respond to the "your content was splattered"
// event, so it's OK to pass a null owner.
}
private static final Toolkit AWT_TOOLKIT = Toolkit.getDefaultToolkit();
private static final Clipboard CLIPBOARD = AWT_TOOLKIT.getSystemClipboard();
}
The full class also has debug and warning methods, but I cut them for brevity and you get the main points anyway. You can use a public static boolean isDebugEnabled to suppress debug messages. If done properly the optimizer will (almost) remove these method calls from your production code. See: http://c2.com/cgi/wiki?ConditionalCompilationInJava

Really hate to dig up this old post but I feel the question deserves another answer specific to windows 8-10.
Using NetworkInformation from the Windows.Networking.Connectivity namespace, you can get the Id of the network adapter windows is using. Then you can get the interface MAC Address from the previously mentioned GetAllNetworkInterfaces().
This will not work in Windows Store Apps as NetworkInterface in System.Net.NetworkInformation does not expose GetAllNetworkInterfaces.
string GetMacAddress()
{
var connectionProfile = NetworkInformation.GetInternetConnectionProfile();
if (connectionProfile == null) return "";
var inUseId = connectionProfile.NetworkAdapter.NetworkAdapterId.ToString("B").ToUpperInvariant();
if(string.IsNullOrWhiteSpace(inUseId)) return "";
var mac = NetworkInterface.GetAllNetworkInterfaces()
.Where(n => inUseId == n.Id)
.Select(n => n.GetPhysicalAddress().GetAddressBytes().Select(b=>b.ToString("X2")))
.Select(macBytes => string.Join(" ", macBytes))
.FirstOrDefault();
return mac;
}

switch (contentType) {
case "web":{
WebView webview = new WebView(this);
//webview.hei;
myLayout.AddView(webview, param);

It was useful for me because I needed the property of view to overlap each other on basis of their appearance, e.g the views get stacked one above other.
put this line at the end of the body. May be the DOM is not ready yet at the moment this line is read by compiler.

I don't know if it's entirely possible to do your ideal pattern. But I found a way to do your first way: CountIF
+-------+-------------------+
| A | B |
+-------+-------------------+
| GL15 | =COUNTIF(A:A, A1) |
+-------+-------------------+
| GL15 | =COUNTIF(A:A, A2) |
+-------+-------------------+
| GL15 | =COUNTIF(A:A, A3) |
+-------+-------------------+
| GL16 | =COUNTIF(A:A, A4) |
+-------+-------------------+
| GL17 | =COUNTIF(A:A, A5) |
+-------+-------------------+
| GL17 | =COUNTIF(A:A, A6) |
+-------+-------------------+
You need to use parentheses: myList.insert([1, 2, 3])
. When you leave out the parentheses, python thinks you are trying to access myList.insert
at position 1, 2, 3
, because that's what brackets are used for when they are right next to a variable.
In the SQL Server Management Studio, to find out details of the active transaction, execute following command
DBCC opentran()
You will get the detail of the active transaction, then from the SPID of the active transaction, get the detail about the SPID using following commands
exec sp_who2 <SPID>
exec sp_lock <SPID>
For example, if SPID is 69 then execute the command as
exec sp_who2 69
exec sp_lock 69
Now , you can kill that process using the following command
KILL 69
I hope this helps :)
A possible CSS ONLY solution can be achived with position: sticky;

The rolling mean returns a Series
you only have to add it as a new column of your DataFrame
(MA
) as described below.
For information, the rolling_mean
function has been deprecated in pandas newer versions. I have used the new method in my example, see below a quote from the pandas documentation.
Warning Prior to version 0.18.0,
pd.rolling_*
,pd.expanding_*
, andpd.ewm*
were module level functions and are now deprecated. These are replaced by using theRolling

You asked where do you see loaded extensions in phpinfo() output.
Answer:
They are listed towards the bottom as separate sections/tables and ONLY if they are loaded. Here is an example of extension Curl loaded.
I installed it on Linux Debian with
sudo apt-get install php7.4-curl
For what it's worth, when I did this I found that no folder should be include in the path in the css file. For instance if I have app/assets/images/example.png
, and I put this in my css file...
div.example { background: url('example.png'); }
... then somehow it magically works. I figured this out by running the rake assets:precompile
task, which just sucks everything out of all your load paths and dumps it in a junk drawer folder: public/assets
. That's ironic, IMO...
In any case this means you don't need to put any folder paths, everything in your assets folders will all end up living in one huge directory. How this system resolves file name conflicts is unclear, you may need to be careful about that.
Kind of frustrating there aren't better docs out there for this big of a change.
This is what I found from one of the Google Maps articles:
- Open Google Maps.
- Make sure the map or Street View image you'd like to embed shows up on the map.
- In the top left corner, click the main menu ?☰.
- Click Share or embed map.
- At the top of the box that appears, choose the Embed map tab.
- Choose the size you want, then copy the code and paste it into the source code of your website or blog.
Note: If you're using Maps in Lite mode, you won't be able to embed a map. Keep in mind that traffic information and some other Maps info might not be available in the embedded map.
Add commons-lang3-3.1.jar in your application build path. Use the below code snippet to trim the String array.
String array = {" String", "Tom Selleck "," Fish "};
array = StringUtils.stripAll(array);
This approach also works with same hierarchy of Controller files:
$printReport = new PrintReportController;
$prinReport->getPrintReport();
I've used accepted answer of this thread many times already. It's great piece of code: Simple and usable. But I usually use babel and ES6 and modules, so if you are like me, here is code to copy for faster developing with ES6
Accepted answer rewritten as module with ES6:
export const createCookie = ({name, value, days}) => {
let expires;
if (days) {
let date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
expires = '; expires=' + date.toGMTString();
} else {
expires = '';
}
document.cookie = name + '=' + value + expires + '; path=/';
};
export const getCookie = ({name}) => {
if (document.cookie.length > 0) {
let c_start = document.cookie.indexOf(name + '=');
if (c_start !== -1) {
c_start = c_start + name.length + 1;
let c_end = document.cookie.indexOf(';', c_start);
if (c_end === -1) {
c_end = document.cookie.length;
}
return unescape(document.cookie.substring(c_start, c_end));
}
}
return '';
};
And after this you can simply import it as any module (path of course may vary):
import {createCookie, getCookie} from './../helpers/Cookie';
Sounds like you're doing this:
0..10.to_a
The warning is from Fixnum#to_a, not from Range#to_a. Try this instead:
(0..10).to_a
new Date('2012.08.10').getTime() / 1000
Check the JavaScript Date documentation.
Do you mean that for a select element with an id of "next" you need to perform some specific script?
$("#next").change(function(){
//enter code here
});
I don't think so. The API's will provide access to delayed quotes, there is no way that real time data or tick data, will be provided for free.
Have you tried doing a full "clean" and then rebuild in Eclipse (Project->Clean...)?
Are you able to compile and run with "javac" and "java" straight from the command line? Does that work properly?
If you right click on your project, go to "Properties" and then go to "Java Build Path", are there any suspicious entries under any of the tabs? This is essentially your CLASSPATH.
In the Eclipse preferences, you may also want to double check the "Installed JREs" section in the "Java" section and make sure it matches what you think it should.
You definitely have either a stale .class file laying around somewhere or you're getting a compile-time/run-time mismatch in the versions of Java you're using.
I tried all of the solutions posted here but none of them worked for me. I managed to disable the time by using this line of code in my jQuery:
$('#datetimepicker4').datetimepicker({
format: 'YYYY-MM-DD'
});
This set the format to date only and disabled the time completely. Hope this helps.
Imagine that we have 3 buttons for example
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Capture our button from layout
Button button = (Button)findViewById(R.id.corky);
Button button2 = (Button)findViewById(R.id.corky2);
Button button3 = (Button)findViewById(R.id.corky3);
// Register the onClick listener with the implementation above
button.setOnClickListener(mCorkyListener);
button2.setOnClickListener(mCorkyListener);
button3.setOnClickListener(mCorkyListener);
}
// Create an anonymous implementation of OnClickListener
private View.OnClickListener mCorkyListener = new View.OnClickListener() {
public void onClick(View v) {
// do something when the button is clicked
// Yes we will handle click here but which button clicked??? We don't know
}
};
}
So what we will do?
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Capture our button from layout
Button button = (Button)findViewById(R.id.corky);
Button button2 = (Button)findViewById(R.id.corky2);
Button button3 = (Button)findViewById(R.id.corky3);
// Register the onClick listener with the implementation above
button.setOnClickListener(mCorkyListener);
button2.setOnClickListener(mCorkyListener);
button3.setOnClickListener(mCorkyListener);
}
// Create an anonymous implementation of OnClickListener
private View.OnClickListener mCorkyListener = new View.OnClickListener() {
public void onClick(View v) {
// do something when the button is clicked
// Yes we will handle click here but which button clicked??? We don't know
// So we will make
switch (v.getId() /*to get clicked view id**/) {
case R.id.corky:
// do something when the corky is clicked
break;
case R.id.corky2:
// do something when the corky2 is clicked
break;
case R.id.corky3:
// do something when the corky3 is clicked
break;
default:
break;
}
}
};
}
Or we can do this:
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Capture our button from layout
Button button = (Button)findViewById(R.id.corky);
Button button2 = (Button)findViewById(R.id.corky2);
Button button3 = (Button)findViewById(R.id.corky3);
// Register the onClick listener with the implementation above
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// do something when the corky is clicked
}
});
button2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// do something when the corky2 is clicked
}
});
button3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// do something when the corky3 is clicked
}
});
}
}
Or we can implement View.OnClickListener and i think it's the best way:
public class MainActivity extends ActionBarActivity implements View.OnClickListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Capture our button from layout
Button button = (Button)findViewById(R.id.corky);
Button button2 = (Button)findViewById(R.id.corky2);
Button button3 = (Button)findViewById(R.id.corky3);
// Register the onClick listener with the implementation above
button.setOnClickListener(this);
button2.setOnClickListener(this);
button3.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// do something when the button is clicked
// Yes we will handle click here but which button clicked??? We don't know
// So we will make
switch (v.getId() /*to get clicked view id**/) {
case R.id.corky:
// do something when the corky is clicked
break;
case R.id.corky2:
// do something when the corky2 is clicked
break;
case R.id.corky3:
// do something when the corky3 is clicked
break;
default:
break;
}
}
}
Finally there is no real differences here Just "Way better than the other"
Go to network Connections within General Preferences ( Windows -> Preferences ) and set "Active Provider" to "Direct"
Reboot your Eclipse after that
You can use the setspace package which gives you spacing environments, e.g.:
\documentclass{article}
\usepackage{setspace}
\begin{document}
\doublespace
my line of text blah blah blah
new line of text with blank line between
\end{document}
Or use a verbatim
environment to control the layout of your code precisely.
string hexString = "8E2";
int num = Int32.Parse(hexString, System.Globalization.NumberStyles.HexNumber);
Console.WriteLine(num);
//Output: 2274
You can find a solution on SuperUser :
Chrome cookies folder in Windows 7:-
C:\Users\your_username\AppData\Local\Google\Chrome\User Data\Default\
You'll need a program like SQLite Database Browser to read it.
For Mac OS X, the file is located at :-
~/Library/Application Support/Google/Chrome/Default/Cookies
This is the simple example to use both of them:
import {
Directive, HostListener, HostBinding
}
from '@angular/core';
@Directive({
selector: '[Highlight]'
})
export class HighlightDirective {
@HostListener('mouseenter') mouseover() {
this.backgroundColor = 'green';
};
@HostListener('mouseleave') mouseleave() {
this.backgroundColor = 'white';
}
@HostBinding('style.backgroundColor') get setColor() {
return this.backgroundColor;
};
private backgroundColor = 'white';
constructor() {}
}
Introduction:
HostListener can bind an event to the element.
HostBinding can bind a style to the element.
this is directive, so we can use it for
Some TextSo according to the debug, we can find that this div has been binded style = "background-color:white"
Some Textwe also can find that EventListener of this div has two event: mouseenter
and mouseleave
. So when we move the mouse into the div, the colour will become green, mouse leave, the colour will become white.
To create a popup you'll need the following script:
<script language="javascript" type="text/javascript">
function popitup(url) {
newwindow=window.open(url,'name','height=200,width=150');
if (window.focus) {newwindow.focus()}
return false;
}
</script>
Then, you link to it by:
<a href="popupex.html" onclick="return popitup('popupex.html')">Link to popup</a>
If you want you can call the function directly from document.ready also. Or maybe from another function.
In additional to the popular K8s, jasypt or vault solutions, there's also Karmahostage. It enables you to do:
@EncryptedValue("${application.secret}")
private String application;
It works the same way jasypt does, but encryption happens on a dedicated saas solution, with a more fine-grained ACL model attached to it.
the question is already solved since quite a long time, but for future reference a possible solution is
b = a.slice(0);
Be careful, this works correctly only if a is a non-nested array of numbers and strings
on branchB do $git checkout branchA
to switch to branch A
on branchA do $git merge branchB
That's all you need.
Try SET GLOBAL slow_query_log = 'ON';
and perhaps FLUSH LOGS;
This assumes you are using MySQL 5.1 or later. If you are using an earlier version, you'll need to restart the server. This is documented in the MySQL Manual. You can configure the log either in the config file or on the command line.
Requests doesn't have an equivalent to Urlib2's read()
.
>>> import requests
>>> response = requests.get("http://www.google.com")
>>> print response.content
'<!doctype html><html itemscope="" itemtype="http://schema.org/WebPage"><head>....'
>>> print response.content == response.text
True
It looks like the POST request you are making is returning no content. Which is often the case with a POST request. Perhaps it set a cookie? The status code is telling you that the POST succeeded after all.
Edit for Python 3:
Python now handles data types differently. response.content
returns a sequence of bytes
(integers that represent ASCII) while response.text
is a string
(sequence of chars).
Thus,
>>> print response.content == response.text
False
>>> print str(response.content) == response.text
True
string[] a = new string[0];
or short notation:
string[] a = { };
The preferred way now is:
var a = Array.Empty<string>();
I have written a short regular expression that you can use in Visual Studio if you want to replace zero-length allocations e.g. new string[0]
.
Use Find (search) in Visual Studio with Regular Expression option turned on:
new[ ][a-zA-Z0-9]+\[0\]
Now Find All or F3 (Find Next) and replace all with Array.Empty<…>() !
Just use "justify-content-center" in the row's class attribute.
<div class="container">
<div class="row justify-content-center">
<h1>This is a header</h1>
</div>
</div>
A simple way using std::next_permutation
:
#include <iostream>
#include <algorithm>
#include <vector>
int main() {
int n, r;
std::cin >> n;
std::cin >> r;
std::vector<bool> v(n);
std::fill(v.end() - r, v.end(), true);
do {
for (int i = 0; i < n; ++i) {
if (v[i]) {
std::cout << (i + 1) << " ";
}
}
std::cout << "\n";
} while (std::next_permutation(v.begin(), v.end()));
return 0;
}
or a slight variation that outputs the results in an easier to follow order:
#include <iostream>
#include <algorithm>
#include <vector>
int main() {
int n, r;
std::cin >> n;
std::cin >> r;
std::vector<bool> v(n);
std::fill(v.begin(), v.begin() + r, true);
do {
for (int i = 0; i < n; ++i) {
if (v[i]) {
std::cout << (i + 1) << " ";
}
}
std::cout << "\n";
} while (std::prev_permutation(v.begin(), v.end()));
return 0;
}
A bit of explanation:
It works by creating a "selection array" (v
), where we place r
selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v
.
You can implement it if you note that for each level r you select a number from 1 to n.
In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance
#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>
using namespace std;
struct combinations
{
typedef vector<int> combination_t;
// initialize status
combinations(int N, int R) :
completed(N < 1 || R > N),
generated(0),
N(N), R(R)
{
for (int c = 1; c <= R; ++c)
curr.push_back(c);
}
// true while there are more solutions
bool completed;
// count how many generated
int generated;
// get current and compute next combination
combination_t next()
{
combination_t ret = curr;
// find what to increment
completed = true;
for (int i = R - 1; i >= 0; --i)
if (curr[i] < N - R + i + 1)
{
int j = curr[i] + 1;
while (i <= R-1)
curr[i++] = j++;
completed = false;
++generated;
break;
}
return ret;
}
private:
int N, R;
combination_t curr;
};
int main(int argc, char **argv)
{
int N = argc >= 2 ? atoi(argv[1]) : 5;
int R = argc >= 3 ? atoi(argv[2]) : 2;
combinations cs(N, R);
while (!cs.completed)
{
combinations::combination_t c = cs.next();
copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
cout << endl;
}
return cs.generated;
}

Person person = personMapRepository.findPerson(id);

Update Nov. 2015: As per Hans Z. below - this is now indeed defined as part of RFC 7662.
Original Answer: The OAuth 2.0 spec (RFC 6749) doesn't clearly define the interaction between a Resource Server (RS) and Authorization Server (AS) for access token (AT) validation. It really depends on the AS's token format/strategy - some tokens are self-contained (like JSON Web Tokens) while others may be similar to a session cookie in that they just reference information held server side back at the AS.
There has been some discussion in the OAuth Working Group about creating a standard way for an RS to communicate with the AS for AT validation. My company (Ping Identity) has come up with one such approach for our commercial OAuth AS (PingFederate): https://support.pingidentity.com/s/document-item?bundleId=pingfederate-93&topicId=lzn1564003025072.html#lzn1564003025072__section_N10578_N1002A_N10001. It uses REST based interaction for this that is very complementary to OAuth 2.0.
MySQL way:

There's also a deprecated PHP function for listing all db tables, take a look at http://php.net/manual/en/function.mysql-list-tables.php

I found that I needed to wrap my datetime string like this:

You can try the code here:
When you ask about:
Blockquote // But what now? How do I display my data? Blockquote
you need to map an array of object, that way:
response([{label: 'result_name', value: 'result_id'},]);
That way when you use the select event of the autocomplete plugin, you can see the result bellow;
You can use the select event that way:
jQuery("#field").autocomplete({
source: function (request, response) {
},
minLength: 3,
select: function(event, ui)
{
console.log(ui);
}
});
I hope that it can help and complement the answers.
There is a super easy solution with flexbox!
.frame {
display: flex;
align-items: center;
}
None of the solutions here worked for me out of the box, but it was most likely due my lack of experience with VBA. It might also be because I simply copied and pasted some of the functions above, not knowing details that maybe are necessary to make them work on a VBA for applications environment.
My needs were simply to send xmlhttp requests using urls that contained some special characters of the Norwegian language. Some of the solutions above encode even colons, which made the urls unsuitable for what I needed.
I then decided to write my own URLEncode function. It does not use more clever programming such as the one from @ndd and @Tom. I am not a very experienced programmer, but I had to make this done sooner.
I realized that the problem was that my server didn't accept UTF-16 encodings, so I had to write a function that would convert UTF-16 to UTF-8. A good source of information was found here and here.
I haven't tested it extensively to check if it works with url with characters that have higher unicode values and which would produce more than 2 bytes of utf-8 characters. I am not saying it will decode everything that needs to be decoded (but it is easy to modify to include/exclude characters on the select case
statement) nor that it will work with higher characters, as I haven't fully tested. But I am sharing the code because it might help someone who is trying to understand the issue.
Any comments are welcome.

PowerShell has really wacky return semantics - at least when viewed from a more traditional programming perspective. There are two main ideas to wrap your head around:
Thus, the following two script blocks will do effectively the exact same thing:
$a = "Hello, World"
return $a
$a = "Hello, World"
$a
return
The $a variable in the second example is left as output on the pipeline and, as mentioned, all output is returned. In fact, in the second example you could omit the return entirely and you would get the same behavior (the return would be implied as the function naturally completes and exits).
Without more of your function definition I can't say why you are getting a PSMethod object. My guess is that you probably have something a few lines up that is not being captured and is being placed on the output pipeline.
It is also worth noting that you probably don't need those semicolons - unless you are nesting multiple expressions on a single line.
You can read more about the return semantics on the about_Return page on TechNet, or by invoking the help return
command from PowerShell itself.
The params object is included in $stateParams, but won't be part of the url.
1) In the route configuration:
$stateProvider.state('edit_user', {
url: '/users/:user_id/edit',
templateUrl: 'views/editUser.html',
controller: 'editUserCtrl',
params: {
paramOne: { objectProperty: "defaultValueOne" }, //default value
paramTwo: "defaultValueTwo"
}
});
2) In the controller:
.controller('editUserCtrl', function ($stateParams, $scope) {
$scope.paramOne = $stateParams.paramOne;
$scope.paramTwo = $stateParams.paramTwo;
});
3A) Changing the State from a controller
$state.go("edit_user", {
user_id: 1,
paramOne: { objectProperty: "test_not_default1" },
paramTwo: "from controller"
});
3B) Changing the State in html
<div ui-sref="edit_user({ user_id: 3, paramOne: { objectProperty: 'from_html1' }, paramTwo: 'fromhtml2' })"></div>
Broadly speaking, spark Executor JVM memory can be divided into two parts. Spark memory and User memory. This is controlled by property spark.memory.fraction
- the value is between 0 and 1.
When working with images or doing memory intensive processing in spark applications, consider decreasing the spark.memory.fraction
. This will make more memory available to your application work. Spark can spill, so it will still work with less memory share.
The second part of the problem is division of work. If possible, partition your data into smaller chunks. Smaller data possibly needs less memory. But if that is not possible, you are sacrifice compute for memory. Typically a single executor will be running multiple cores. Total memory of executors must be enough to handle memory requirements of all concurrent tasks. If increasing executor memory is not a option, you can decrease the cores per executor so that each task gets more memory to work with. Test with 1 core executors which have largest possible memory you can give and then keep increasing cores until you find the best core count.
Just learned relevant skill from Python for Everybody.
You may use a temporary list to help you to sort the dictionary:
#Assume dictionary to be:
d = {'apple': 500.1, 'banana': 1500.2, 'orange': 1.0, 'pineapple': 789.0}
# create a temporary list
tmp = []
# iterate through the dictionary and append each tuple into the temporary list
for key, value in d.items():
tmptuple = (value, key)
tmp.append(tmptuple)
# sort the list in ascending order
tmp = sorted(tmp)
print (tmp)
If you want to sort the list in descending order, simply change the original sorting line to:
tmp = sorted(tmp, reverse=True)
Using list comprehension, the one liner would be:
#Assuming the dictionary looks like
d = {'apple': 500.1, 'banana': 1500.2, 'orange': 1.0, 'pineapple': 789.0}
#One liner for sorting in ascending order
print (sorted([(v, k) for k, v in d.items()]))
#One liner for sorting in descending order
print (sorted([(v, k) for k, v in d.items()], reverse=True))
Sample Output:
#Asending order
[(1.0, 'orange'), (500.1, 'apple'), (789.0, 'pineapple'), (1500.2, 'banana')]
#Descending order
[(1500.2, 'banana'), (789.0, 'pineapple'), (500.1, 'apple'), (1.0, 'orange')]

I created the following procedure
:
if object_id('tool.create_insert', 'P') is null
begin
exec('create procedure tool.create_insert as');
end;
go
alter procedure tool.create_insert(@schema varchar(200) = 'dbo',
@table varchar(200),
@where varchar(max) = null,
@top int = null,
@insert varchar(max) output)
as
begin
declare @insert_fields varchar(max),
@select varchar(max),
@error varchar(500),
@query varchar(max);
declare @values table(description varchar(max));
set nocount on;
-- Get columns
select @insert_fields = isnull(@insert_fields + ', ', '') + c.name,
@select = case type_name(c.system_type_id)
when 'varchar' then isnull(@select + ' + '', '' + ', '') + ' isnull('''''''' + cast(' + c.name + ' as varchar) + '''''''', ''null'')'
when 'datetime' then isnull(@select + ' + '', '' + ', '') + ' isnull('''''''' + convert(varchar, ' + c.name + ', 121) + '''''''', ''null'')'
else isnull(@select + ' + '', '' + ', '') + 'isnull(cast(' + c.name + ' as varchar), ''null'')'
end
from sys.columns c with(nolock)
inner join sys.tables t with(nolock) on t.object_id = c.object_id
inner join sys.schemas s with(nolock) on s.schema_id = t.schema_id
where s.name = @schema
and t.name = @table;
-- If there's no columns...
if @insert_fields is null or @select is null
begin
set @error = 'There''s no ' + @schema + '.' + @table + ' inside the target database.';
raiserror(@error, 16, 1);
return;
end;
set @insert_fields = 'insert into ' + @schema + '.' + @table + '(' + @insert_fields + ')';
if isnull(@where, '') <> '' and charindex('where', ltrim(rtrim(@where))) < 1
begin
set @where = 'where ' + @where;
end
else
begin
set @where = '';
end;
set @query = 'select ' + isnull('top(' + cast(@top as varchar) + ')', '') + @select + ' from ' + @schema + '.' + @table + ' with (nolock) ' + @where;
insert into @values(description)
exec(@query);
set @insert = isnull(@insert + char(10), '') + '--' + upper(@schema + '.' + @table);
select @insert = @insert + char(10) + @insert_fields + char(10) + 'values(' + v.description + ');' + char(10) + 'go' + char(10)
from @values v
where isnull(v.description, '') <> '';
end;
go
Then you can use it that way:
declare @insert varchar(max),
@part varchar(max),
@start int,
@end int;
set @start = 1;
exec tool.create_insert @schema = 'dbo',
@table = 'myTable',
@where = 'Fk_CompanyId = 1',
@insert = @insert output;
-- Print one line to avoid the maximum 8000 characters problem
while len(@insert) > 0
begin
set @end = charindex(char(10), @insert);
if @end = 0
begin
set @end = len(@insert) + 1;
end;
print substring(@insert, @start, @end - 1);
set @insert = substring(@insert, @end + 1, len(@insert) - @end + 1);
end;
The output would be something like that:
--DBO.MYTABLE
insert into dbo.myTable(Pk_Id, ProductName, Fk_CompanyId, Price)
values(1, 'AMX', 1, 10.00);
go
insert into dbo.myTable(Pk_Id, ProductName, Fk_CompanyId, Price)
values(2, 'ABC', 1, 11.00);
go
insert into dbo.myTable(Pk_Id, ProductName, Fk_CompanyId, Price)
values(3, 'APEX', 1, 12.00);
go
insert into dbo.myTable(Pk_Id, ProductName, Fk_CompanyId, Price)
values(4, 'AMX', 1, 10.00);
go
insert into dbo.myTable(Pk_Id, ProductName, Fk_CompanyId, Price)
values(5, 'ABC', 1, 11.00);
go
insert into dbo.myTable(Pk_Id, ProductName, Fk_CompanyId, Price)
values(6, 'APEX', 1, 12.00);
go
insert into dbo.myTable(Pk_Id, ProductName, Fk_CompanyId, Price)
values(7, 'AMX', 2, 10.00);
go
insert into dbo.myTable(Pk_Id, ProductName, Fk_CompanyId, Price)
values(8, 'ABC', 2, 11.00);
go
insert into dbo.myTable(Pk_Id, ProductName, Fk_CompanyId, Price)
values(9, 'APEX', 2, 12.00);
go
If you just want to get a range of rows, use the @top
parameter as bellow:
declare @insert varchar(max),
@part varchar(max),
@start int,
@end int;
set @start = 1;
exec tool.create_insert @schema = 'dbo',
@table = 'myTable',
@top = 100,
@insert = @insert output;
-- Print one line to avoid the maximum 8000 characters problem
while len(@insert) > 0
begin
set @end = charindex(char(10), @insert);
if @end = 0
begin
set @end = len(@insert) + 1;
end;
print substring(@insert, @start, @end - 1);
set @insert = substring(@insert, @end + 1, len(@insert) - @end + 1);
end;
Step 1:
The object locator supposed to be used here is XPath. So derive the XPath for those two checkboxes.
String housingmoves="//label[contains(text(),'housingmoves')]/preceding-sibling::input";
String season_country_homes="//label[contains(text(),'Seaside & Country Homes')]/preceding-sibling::input";
Step 2:
Perform a click on the checkboxes
driver.findElement(By.xpath(housingmoves)).click();
driver.findElement(By.xpath(season_country_homes)).click();
int w =0 , l =0, d=0, i=0;
Scanner sc = new Scanner(System.in);
// try tentimes
while (i<10) {
System.out.println("scissor(1) ,Rock(2),Paper(3) ");
int n = sc.nextInt();
int m =(int)(Math.random()*3+1);
if(n==m){
System.out.println("Com:"+m +"so>>> " + "draw");
d++;
}else if ((n-1)%3==(m%3)){
w++;
System.out.println("Com:"+m +"so>>> " +"win");
}
else if(n >=4 )
{
System.out.println("pleas enter correct number)");
}
else {
System.out.println("Com:"+m +"so>>> " +"lose");
l++;
}
i++;
I had the problem, I had to replace "Not Available" with NA
and my solution goes like this
data <- sapply(data,function(x) {x <- gsub("Not Available",NA,x)})
Here is another way to do it:
#!/bin/bash
# Read Password
echo -n Password:
read -s password
echo
# Run Command
echo $password
The read -s
will turn off echo for you. Just replace the echo
on the last line with the command you want to run.
I agree with some comments about NOLOCK hint and especially with those saying "use it when it's appropriate". If the application written poorly and is using concurrency inappropriate way – that may cause the lock escalation. Highly transactional table also are getting locked all the time due to their nature. Having good index coverage won't help with retrieving the data, but setting ISOLATION LEVEL to READ UNCOMMITTED does. Also I believe that using NOLOCK hint is safe in many cases when the nature of changes is predictable. For example – in manufacturing when jobs with travellers are going through different processes with lots of inserts of measurements, you can safely execute query against the finished job with NOLOCK hint and this way avoid collision with other sessions that put PROMOTED or EXCLUSIVE locks on the table/page. The data you access in this case is static, but it may reside in a very transactional table with hundreds of millions of records and thousands updates/inserts per minute. Cheers
You have to use querySelectorAll
as you need to select all elements with the said class, again since querySelectorAll
is an array you need to iterate it and add the event handlers
var deleteLinks = document.querySelectorAll('.delete');
for (var i = 0; i < deleteLinks.length; i++) {
deleteLinks[i].addEventListener('click', function (event) {
event.preventDefault();
var choice = confirm("sure u want to delete?");
if (choice) {
return true;
}
});
}
You may wonder, why the syntax is valid (but not working as expected):
var func = p => { foo: "bar" }
It's because of JavaScript's label syntax:
So if you transpile the above code to ES5, it should look like:
var func = function (p) {
foo:
"bar"; //obviously no return here!
}
This Should Work Fine
SELECT * FROM product
WHERE pdate BETWEEN datetime('now', '-30 days') AND datetime('now', 'localtime')
I would use cron to run a script every minute, and make that script run your script four times with a 15-second sleep between runs.
(That assumes your script is quick to run - you could adjust the sleep times if not.)
That way, you get all the benefits of cron
as well as your 15 second run period.
Edit: See also @bmb's comment below.
string[] array = { "cat", "dot", "perls" };
// Use Array.Exists in different ways.
bool a = Array.Exists(array, element => element == "perls");
bool b = Array.Exists(array, element => element == "python");
bool c = Array.Exists(array, element => element.StartsWith("d"));
bool d = Array.Exists(array, element => element.StartsWith("x"));
// Display bools.
Console.WriteLine(a);
Console.WriteLine(b);
Console.WriteLine(c);

To me the solution was to go to
Run > Edit Configuration > Defaults > Python
then manage the
checkboxes, as well as setting the "Working directory" field.
If you have set up your own Run/Debug Configurations then you might want to go to
Run > Edit Configuration > Python > [Whatever you called your config]
and edit it there.
My problem was that I wanted to have my whole repository included in my PyCharm 2016.2 project, but only a subfolder was the actual python source code root. I added it as "Source Root" by right clicking the folder then
Mark directory as > Source Root
Then unchecking "Add content roots to PYTHONPATH" and checking "Add source root to PYTHONPATH" in the Run/Debug config menu. I then checked the folder pathing by doing:
import sys
logger.info(sys.path)
This outputed:
[
'/usr/local/my_project_root/my_sources_root',
'/usr/local/my_project_root/my_sources_root',
'/usr/lib/python3.4', '/usr/lib/python3.4/plat-x86_64-linux-gnu',
'/usr/lib/python3.4/lib-dynload',
'/usr/local/lib/python3.4/dist-packages',
'/usr/lib/python3/dist-packages'
]
However, without the fix it said:
[
'/usr/local/my_project_root/my_sources_root',
'/usr/local/my_project_root', <-- NOT WANTED
'/usr/lib/python3.4',
'/usr/lib/python3.4/plat-x86_64-linux-gnu',
'/usr/lib/python3.4/lib-dynload',
'/usr/local/lib/python3.4/dist-packages',
'/usr/lib/python3/dist-packages'
]
Which meant I got the project root folder included. This messed up the pathing for me.

Edit: Previous table-based image positioning had issues in Internet Explorer 11 (max-height
doesn't work in display:table
elements). I've replaced it with inline based positioning which not only works fine in both Internet Explorer 7 and Internet Explorer 11, but it also requires less code.
Here is my take on the subject. It'll only work if the container has a specified size (max-width
and max-height
don't seem to get along with containers that don't have concrete size), but I wrote the CSS content in a way that allows it to be reused (add picture-frame
class and px125
size class to your existing container).
In CSS:
.picture-frame
{
vertical-align: top;
display: inline-block;
text-align: center;
}
.picture-frame.px125
{
width: 125px;
height: 125px;
line-height: 125px;
}
.picture-frame img
{
margin-top: -4px; /* Inline images have a slight offset for some reason when positioned using vertical-align */
max-width: 100%;
max-height: 100%;
display: inline-block;
vertical-align: middle;
border: 0; /* Remove border on images enclosed in anchors in Internet Explorer */
}
And in HTML:
<a href="#" class="picture-frame px125">
<img src="http://i.imgur.com/lesa2wS.png"/>

Edit: Possible further improvement using JavaScript (upscaling images):
function fixImage(img)
{
var $this = $(img);
var parent = $this.closest('.picture-frame');
if ($this.width() == parent.width() || $this.height() == parent.height())
return;
if ($this.width() > $this.height())
$this.css('width', parent.width() + 'px');
else
$this.css('height', parent.height() + 'px');
}
$('.picture-frame img:visible').each(function
{
if (this.complete)
fixImage(this);
else
this.onload = function(){ fixImage(this) };
});
For me, the problem was twofold: First, the version of IIS I was dealing with didn't know about the .woff2
MIME type, only about .woff
. I fixed that using IIS Manager at the server level, not at the web app level, so the setting wouldn't get overridden with each new app deployment. (Under IIS Manager, I went to MIME types, and added the missing .woff2
, then updated .woff
.)
Second, and more importantly, I was bundling bootstrap.css
along with some other files as "~/bundles/css/site"
. Meanwhile, my font files were in "~/fonts"
. bootstrap.css
looks for the glyphicon fonts in "../fonts"
, which translated to "~/bundles/fonts"
-- wrong path.
In other words, my bundle path was one directory too deep. I renamed it to "~/bundles/siteCss"
, and updated all the references to it that I found in my project. Now bootstrap looked in "~/fonts"
for the glyphicon files, which worked. Problem solved.
Before I fixed the second problem above, none of the glyphicon
font files were loading. The symptom was that all instances of glyphicon
glyphs in the project just showed an empty box. However, this symptom only occurred in the deployed versions of the web app, not on my dev machine. I'm still not sure why that was the case.
Keys must be comparable, but you haven't defined a suitable operator<

Here is how to make an authenticated POST request, using Refinery as an example:
# Start Rails console
rails console
# Get the login form
app.get '/community_members/sign_in'
# View the session
app.session.to_hash
# Copy the CSRF token "_csrf_token" and place it in the login request.
# Log in from the console to create a session
app.post '/community_members/login', {"authenticity_token"=>"gT7G17RNFaWUDLC6PJGapwHk/OEyYfI1V8yrlg0lHpM=", "refinery_user[login]"=>'chloe', 'refinery_user[password]'=>'test'}
# View the session to verify CSRF token is the same
app.session.to_hash
# Copy the CSRF token "_csrf_token" and place it in the request. It's best to edit this in Notepad++
app.post '/refinery/blog/posts', {"authenticity_token"=>"gT7G17RNFaWUDLC6PJGapwHk/OEyYfI1V8yrlg0lHpM=", "switch_locale"=>"en", "post"=>{"title"=>"Test", "homepage"=>"0", "featured"=>"0", "magazine"=>"0", "refinery_category_ids"=>["1282"], "body"=>"Tests do a body good.", "custom_teaser"=>"", "draft"=>"0", "tag_list"=>"", "published_at(1i)"=>"2014", "published_at(2i)"=>"5", "published_at(3i)"=>"27", "published_at(4i)"=>"21", "published_at(5i)"=>"20", "custom_url"=>"", "source_url_title"=>"", "source_url"=>"", "user_id"=>"56", "browser_title"=>"", "meta_description"=>""}, "continue_editing"=>"false", "locale"=>:en}
You might find these useful too if you get an error:

It is XOR. Another name for the XOR function is addition without carry. I suppose that's how the symbol might make sense.
I found the answer I was looking for. The thing to use here is the construct of
\left \middle \right
For example, in this case, two possible solutions are:
$\left( {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right) $
Or, in case the brackets are not necessary:
$\left. {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right. $
I can't find anything that deals with clock times exactly, so I'd just use some functions from package:lubridate and work with seconds-since-midnight:
require(lubridate)
clockS = function(t){hour(t)*3600+minute(t)*60+second(t)}
plot(clockS(times),val)
You might then want to look at some of the axis code to figure out how to label axes nicely.
Just enter plt.hold(False)
before the first plt.plot, and you can stick to your original code.
Do not create separate lists; create a list of lists:
results = []
with open('inputfile.txt') as inputfile:
for line in inputfile:
results.append(line.strip().split(','))
or better still, use the csv
module:
import csv
results = []
with open('inputfile.txt', newline='') as inputfile:
for row in csv.reader(inputfile):
results.append(row)
Lists or dictionaries are far superiour structures to keep track of an arbitrary number of things read from a file.
Note that either loop also lets you address the rows of data individually without having to read all the contents of the file into memory either; instead of using results.append()
just process that line right there.
Just for completeness sake, here's the one-liner compact version to read in a CSV file into a list in one go:
import csv
with open('inputfile.txt', newline='') as inputfile:
results = list(csv.reader(inputfile))
public static string GetCurrentWebsiteRoot()
{
return HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority);
}
You could still use sortBy (at the collection level) instead of orderBy (at the query level) if you still want to use all() since it returns a collection of objects.
Ascending Order
$results = Project::all()->sortBy("name");
Descending Order
$results = Project::all()->sortByDesc("name");
Check out the documentation about Collections for more details.
If I'm understanding you correctly, you should be able to do this in one query, joining table1 and table2 together:
INSERT INTO table3 { name, age, sex, city, id, number}
SELECT p.name, p.age, p.sex, p.city, p.id, c.number
FROM table1 p
INNER JOIN table2 c ON c.Id = p.Id
Just to go a little bit further in the matter, you can also set a bitmap directly, like this:
ImageView imageView = new ImageView(this);
Bitmap bImage = BitmapFactory.decodeResource(this.getResources(), R.drawable.my_image);
imageView.setImageBitmap(bImage);
Of course, this technique is only useful if you need to change the image.
COUNTIF function will only count cells that contain numbers in your specified range.
COUNTA(range) will count all values in the list of arguments. Text entries and numbers are counted, even when they contain an empty string of length 0.
Example: Function in A7 =COUNTA(A1:A6)
Range:
A1 a
A2 b
A3 banana
A4 42
A5
A6
A7 4 -> result

Below approach of frame handling : When no id or name is given incase of nested frame
WebElement element =driver.findElement(By.xpath(".//*[@id='block-block19']//iframe"));
driver.switchTo().frame(element);
driver.findElement(By.xpath(".//[@id='carousel']/li/div/div[3]/a")).click();
echo array_search("car",array_keys($a));
Remember to not capitalize your text when writing this command. For example:
Do write:
rails g model product title:string description:text image_url:string price:decimal
Do not write:
rails g Model product title:string description:text image_url:string price:decimal
At least it was a problem to me.
We needed unsigned numbers to model MySQL's unsigned TINYINT
, SMALLINT
, INT
, BIGINT
in jOOQ, which is why we have created jOOU, a minimalistic library offering wrapper types for unsigned integer numbers in Java. Example:
import static org.joou.Unsigned.*;
// and then...
UByte b = ubyte(1);
UShort s = ushort(1);
UInteger i = uint(1);
ULong l = ulong(1);
All of these types extend java.lang.Number
and can be converted into higher-order primitive types and BigInteger
. Hope this helps.

If your intention was to find a way to represent null in an enumeration of singleton objects, then it's a bad idea to (de)reference null (it C++11, nullptr).
Why not declare static singleton object that represents NULL within the class as follows and add a cast-to-pointer operator that returns nullptr ?
Edit: Corrected several mistypes and added if-statement in main() to test for the cast-to-pointer operator actually working (which I forgot to.. my bad) - March 10 2015 -
// Error.h
class Error {
public:
static Error& NOT_FOUND;
static Error& UNKNOWN;
static Error& NONE; // singleton object that represents null
public:
static vector<shared_ptr<Error>> _instances;
static Error& NewInstance(const string& name, bool isNull = false);
private:
bool _isNull;
Error(const string& name, bool isNull = false) : _name(name), _isNull(isNull) {};
Error() {};
Error(const Error& src) {};
Error& operator=(const Error& src) {};
public:
operator Error*() { return _isNull ? nullptr : this; }
};
// Error.cpp
vector<shared_ptr<Error>> Error::_instances;
Error& Error::NewInstance(const string& name, bool isNull = false)
{
shared_ptr<Error> pNewInst(new Error(name, isNull)).
Error::_instances.push_back(pNewInst);
return *pNewInst.get();
}
Error& Error::NOT_FOUND = Error::NewInstance("NOT_FOUND");
//Error& Error::NOT_FOUND = Error::NewInstance("UNKNOWN"); Edit: fixed
//Error& Error::NOT_FOUND = Error::NewInstance("NONE", true); Edit: fixed
Error& Error::UNKNOWN = Error::NewInstance("UNKNOWN");
Error& Error::NONE = Error::NewInstance("NONE");
// Main.cpp
#include "Error.h"
Error& getError() {
return Error::UNKNOWN;
}
// Edit: To see the overload of "Error*()" in Error.h actually working
Error& getErrorNone() {
return Error::NONE;
}
int main(void) {
if(getError() != Error::NONE) {
return EXIT_FAILURE;
}
// Edit: To see the overload of "Error*()" in Error.h actually working
if(getErrorNone() != nullptr) {
return EXIT_FAILURE;
}
}
Your anchor tag should be:
<a id="loginLink" onclick="showHideTable();" href="#">Login</a>
And You javascript function :
function showHideTable()
{
if (document.getElementById("loginTable").style.display == "none" ) {
document.getElementById("loginTable").style.display="";
} else {
document.getElementById("loginTable").style.display="none";
}
Use the radix parameter of parseInt
:
var binary = "1101000";
var digit = parseInt(binary, 2);
console.log(digit);
Android changed how permissions work with Android 6.0 that's the reason for your errors. You have to actually request and check if the permission was granted by user to use. So permissions in manifest file will only work for api below 21. Check this link for a snippet of how permissions are requested in api23 http://android-developers.blogspot.nl/2015/09/google-play-services-81-and-android-60.html?m=1
Code:-

PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, STORAGE_PERMISSION_RC);
return;
}`
` @Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == STORAGE_PERMISSION_RC) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//permission granted start reading
} else {
Toast.makeText(this, "No permission to read external storage.", Toast.LENGTH_SHORT).show();
}
}
}
}

I think it has more to do with how Windows is configured as hinted by this response: Java -Xmx Option
Some more testing: I was able to allocate 1300MB on an old Windows XP machine with only 768MB physical RAM (plus virtual memory). On my 2GB RAM machine I can only get 1220MB. On various other corporate machines (with older Windows XP) I was able to get 1400MB. The machine with a 1220MB limit is pretty new (just purchased from Dell), so maybe it has newer (and more bloated) Windows and DLLs (it's running Window XP Pro Version 2002 SP2).
Better to have this things in info.plist
<key>UIStatusBarHidden</key>
<true/>
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>
this makes no status bar at all.
I've wrestled with this myself, trying to make it work from the server. Couldn't. Instead...
To clarify on @dnc253's answer, $window.open(URL)
is a method for having an Angular application open a given URL in another window. (It's really just a testable angular proxy for the universal window.open()
.) This is a great solution, preserves your history, and gets the file downloaded and possibly renders it in that fresh browser window if that's supported. But it often runs into popup blockers, which is a huge problem for reliability. Users often simply don't understand what's going on with them. So, if you don't mind immediately downloading the file with the current window, you can simply use the equally effective universal javascript method: location.href = "uriString"
, which works like a charm for me. Angular doesn't even realize anything has happened. I call it in a promise handler for once my POST/PUT operation has completed. If need be, have the POST/PUT return the URL to call, if you can't already infer it. You'll get the same behavior for the user as if it had downloaded in response to the PUT/POST. For example:
$http.post(url, payload).then(function(returnData){
var uriString = parseReturn(returnData);
location.href="uriString"
})
You can, in fact, download something directly from an XHR request, but it requires full support for the HTML5 file API and is usually more trouble than it's worth unless you need to perform local transformations upon the file before you make it available to the user. (Sadly, I lack the time to provide details on that but there are other SO posts about using it.)
As JavaScript is client side and JSP is Server side.
So Javascript does not execute until it gets to the browser, But Java executes on the server. So, Java does not know the value of the JavaScript variable.
However you assign value of Java variable to JavaScript variable.
The Background
property expects a Brush
object, not a string. Change the type of the property to Brush
and initialize it thus:
Background = new SolidColorBrush(Colors.Red);
Here is an example which gets big numbers very quickly.
import java.math.BigInteger;
/*
250000th fib # is: 36356117010939561826426 .... 10243516470957309231046875

*/
public class Main {
public static void main(String... args) {
int place = args.length > 0 ? Integer.parseInt(args[0]) : 250 * 1000;
long start = System.nanoTime();
BigInteger fibNumber = fib(place);
long time = System.nanoTime() - start;
System.out.println(place + "th fib # is: " + fibNumber);
System.out.printf("Time to compute: %5.1f seconds.%n", time / 1.0e9);
}
private static BigInteger fib(int place) {
BigInteger a = new BigInteger("0");
BigInteger b = new BigInteger("1");
while (place-- > 1) {
BigInteger t = b;
b = a.add(b);
a = t;
}
return b;
}
}
Here is a more generic solution based on @rindeal solution which does not work on MacOS/BSD (/r
expects a file):
cat << DOC > input.txt
abc
cdef
line
DOC
$ cat << EOF | sed '/^cdef$/ r /dev/stdin' input.txt
line 1
line 2
EOF
# outputs:
abc
cdef
line 1
line 2
line
This can be used to pipe anything into the file at the given position:
$ date | sed '/^cdef$/ r /dev/stdin' input.txt
# outputs
abc
cdef
Tue Mar 17 10:50:15 CET 2020
line
Also, you could add multiple commands which allows deleting the marker line cdef
:
$ date | sed '/^cdef$/ {
r /dev/stdin
d
}' input.txt
# outputs
abc
Tue Mar 17 10:53:53 CET 2020
line
It's as simple as this: the JBoss docs are not 100% perfectly well-maintained. Go with what the JavaDoc says: buildSessionFactory(ServiceRegistry serviceRegistry)
.
It could be hardware. It could be something complicated...but I'd take a stab at suggesting that somewhere your threading code is not protecting some collection (such as a dictionary) with an appropriate lock.
What OS and service pack are you running?
I think that the Import-Module

Use the following steps for setup
Download from Flutter SDK for Mac https://flutter.dev/docs/get-started/install/macos
Extract the Flutter SDK zip (saved in Downloads) file using terminal. If you want to extract the Flutter SDK in fluttrerDevelopment folder
$ cd ~/fluttrerDevelopment
$ unzip ~/Downloads/flutter_macos_1.20.1-stable.zip
Add the flutter tool to your path:
$ export PATH=“$PATH:pwd
/flutter/bin"
If you have only Xcode setup in your machine then run
$ flutter create my_first_flutter_app
$ cd my_first_flutter_app
$ flutter run
This has been a difficult problem for me to solve. How can I build a dynamic link in razor and html that can call an action method and pass a value or values to a specific action method? I considered several options including a custom html helper. I just came up with a simple and elegant solution.
The view
@model IEnumerable<MyMvcApp.Models.Product>
@using (Html.BeginForm()) {
<table>
<thead>
<tr>
<td>Name</td>
<td>Price</td>
<td>Quantity</td>
</tr>
</thead>
@foreach (Product p in Model.Products)
{
<tr>
<td><a href="@Url.Action("Edit", "Product", p)">@p.Name</a></td>
<td>@p.Price.ToString()</td>
<td>@p.Quantity.ToString()</td>
</tr>
}
</table>
}
The action method
public ViewResult Edit(Product prod)
{
ContextDB contextDB = new ContextDB();
Product product = contextDB.Products.Single(p => p.ProductID == prod.ProductId);
product = prod;
contextDB.SaveChanges();
return View("Edit");
}
The point here is that Url.Action does not care whether the action method is a GET or a POST. It will access either type of method. You can pass your data to the action method using
@Url.Action(string actionName, string controllerName, object routeValues)
the routeValues object. I have tried this and it works. No, you are not technically doing a post or submitting the form but if the routeValues object contains your data, it doesnt matter if its a post or a get. You can use a particular action method signature to select the right method.
Via Bootstrap Grid, you can easily get the cross browser compatible solution.

You could use a "variable" inside the output filename, for example:
/tmp/FetchBlock-${current_date}.txt
current_date:
Returns the current system time formatted as yyyyMMdd_HHmm. An optional argument can be used to provide alternative formatting. The argument must be valid pattern for java.util.SimpleDateFormat.
Or you can also use a system_property or an env_var to specify something dynamic (either one needs to be specified as arguments)

The alternative for explode in php is split.
The first parameter is the delimiter, the second parameter the maximum number splits. The parts are returned without the delimiter present (except possibly the last part). When the delimiter is None, all whitespace is matched. This is the default.
>>> "Rajasekar SP".split()
['Rajasekar', 'SP']
>>> "Rajasekar SP".split('a',2)
['R','j','sekar SP']
I faced this error (errno 121) but it was caused by mysql-created intermediate tables that had been orphaned, preventing me from altering a table even though no such constraint name existed across any of my tables. At some point, my MySQL had crashed or failed to cleanup an intermediate table (table name starting with a #sql-) which ended up presenting me with an error such as: Can't create table '#sql-' (errno 121) when trying to run an ALTER TABLE with certain constraint names.
According to the docs at http://dev.mysql.com/doc/refman/5.7/en/innodb-troubleshooting-datadict.html , you can search for these orphan tables with:
SELECT * FROM INFORMATION_SCHEMA.INNODB_SYS_TABLES WHERE NAME LIKE '%#sql%';
The version I was working with was 5.1, but the above command only works on versions >= 5.6 (manual is incorrect about it working for 5.5 or earlier, because INNODB_SYS_TABLES does not exist in such versions). I was able to find the orphaned temporary table (which did not match the one named in the message) by searching my mysql data directory in command line:
find . -iname '#*'
After discovering the filename, such as #sql-9ad_15.frm, I was able to drop that orphaned table in MySQL:
USE myschema;
DROP TABLE `#mysql50##sql-9ad_15`;
After doing so, I was then able to successfully run my ALTER TABLE.
For completeness, as per the MySQL documentation linked, "the #mysql50# prefix tells MySQL to ignore file name safe encoding introduced in MySQL 5.1."
As you have define the id in int type at the database creation, you have to use the same data type in the model class too. And as you have defined the id to auto increment in the database, you have to mention it in the model class by passing value 'GenerationType.AUTO' into the attribute 'strategy' within the annotation @GeneratedValue. Then the code becomes as below.
@Entity
public class Operator{
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int id;
private String username;
private String password;
private Integer active;
//Getters and setters...
}
This will basically do it at the most simple level:
"use strict";
var name = "foo";
var func = new Function(
"return function " + name + "(){ alert('sweet!')}"
)();
//call it, to test it
func();
If you want to get more fancy, I have a written an article on "Dynamic function names in JavaScript".

String result = data.toURI();
// ...
}
}

Try this. Oracle has this feature to distinguish the millennium years..
As you mentioned, if your column is a varchar, then the below query will yield you 1989..
select to_date(column_name,'dd/mm/rr') from table1;
When the format rr is used in year, the following would be done by oracle.
if rr->00 to 49 ---> result will be 2000 - 2049, if rr->50 to 99 ---> result will be 1950 - 1999
I ran into a similar issue with getting SSL to work on a port other than port 443. In my case I had a bundle certificate as well as a certificate and a key. The bundle certificate is a file that holds multiple certificates, node requires that you break those certificates into separate elements of an array.
var express = require('express');
var https = require('https');
var fs = require('fs');
var options = {
ca: [fs.readFileSync(PATH_TO_BUNDLE_CERT_1), fs.readFileSync(PATH_TO_BUNDLE_CERT_2)],
cert: fs.readFileSync(PATH_TO_CERT),
key: fs.readFileSync(PATH_TO_KEY)
};
app = express()
app.get('/', function(req,res) {
res.send('hello');
});
var server = https.createServer(options, app);
server.listen(8001, function(){
console.log("server running at https://IP_ADDRESS:8001/")
});
In app.js you need to specify https and create the server accordingly. Also, make sure that the port you're trying to use is actually allowing inbound traffic.
you can split using a third party software http://www.hjsplit.org/, for example give yours input that could be upto 9GB and then split, in my case I split 10 MB each
Here is what I would recommend.
It should conform to C89, and be completely portable. In particular, it works also on pipes and sockets on POSIXy systems.
The idea is that we read the input in large-ish chunks (READALL_CHUNK
), dynamically reallocating the buffer as we need it. We only use realloc()
, fread()
, ferror()
, and free()
:
#include <stdlib.h>
#include <stdio.h>
#include <errno.h>
/* Size of each input chunk to be
read and allocate for. */
#ifndef READALL_CHUNK
#define READALL_CHUNK 262144
#endif
#define READALL_OK 0 /* Success */
#define READALL_INVALID -1 /* Invalid parameters */
#define READALL_ERROR -2 /* Stream error */
#define READALL_TOOMUCH -3 /* Too much input */
#define READALL_NOMEM -4 /* Out of memory */
/* This function returns one of the READALL_ constants above.
If the return value is zero == READALL_OK, then:
(*dataptr) points to a dynamically allocated buffer, with
(*sizeptr) chars read from the file.
The buffer is allocated for one extra char, which is NUL,
and automatically appended after the data.
Initial values of (*dataptr) and (*sizeptr) are ignored.
*/
int readall(FILE *in, char **dataptr, size_t *sizeptr)
{
char *data = NULL, *temp;
size_t size = 0;
size_t used = 0;
size_t n;
/* None of the parameters can be NULL. */
if (in == NULL || dataptr == NULL || sizeptr == NULL)
return READALL_INVALID;
/* A read error already occurred? */
if (ferror(in))
return READALL_ERROR;
while (1) {
if (used + READALL_CHUNK + 1 > size) {
size = used + READALL_CHUNK + 1;
/* Overflow check. Some ANSI C compilers
may optimize this away, though. */
if (size <= used) {
free(data);
return READALL_TOOMUCH;
}
temp = realloc(data, size);
if (temp == NULL) {
free(data);
return READALL_NOMEM;
}
data = temp;
}
n = fread(data + used, 1, READALL_CHUNK, in);
if (n == 0)
break;
used += n;
}
if (ferror(in)) {
free(data);
return READALL_ERROR;
}
temp = realloc(data, used + 1);
if (temp == NULL) {
free(data);
return READALL_NOMEM;
}
data = temp;
data[used] = '\0';
*dataptr = data;
*sizeptr = used;
return READALL_OK;
}
Above, I've used a constant chunk size, READALL_CHUNK
== 262144 (256*1024
). This means that in the worst case, up to 262145 chars are wasted (allocated but not used), but only temporarily. At the end, the function reallocates the buffer to the optimal size. Also, this means that we do four reallocations per megabyte of data read.
The 262144-byte default in the code above is a conservative value; it works well for even old minilaptops and Raspberry Pis and most embedded devices with at least a few megabytes of RAM available for the process. Yet, it is not so small that it slows down the operation (due to many read calls, and many buffer reallocations) on most systems.
For desktop machines at this time (2017), I recommend a much larger READALL_CHUNK
, perhaps #define READALL_CHUNK 2097152
(2 MiB).
Because the definition of READALL_CHUNK
is guarded (i.e., it is defined only if it is at that point in the code still undefined), you can override the default value at compile time, by using (in most C compilers) -DREADALL_CHUNK=2097152
command-line option -- but do check your compiler options for defining a preprocessor macro using command-line options.
Just wanted to point out that in the case of having a hidden submit button, you can just use the ngShow directive and set it to false like so:
HTML
<form ng-submit="myFunc()">
<input type="text" name="username">
<input type="submit" value="submit" ng-show="false">
</form>
Just add map:
" ~/.vimrc
inoremap <c-p> <c-r>*
restart vim and when press Crtl+p
in insert mode,
copied text will be pasted
Above answer is very correct but I'm giving an easy step to do it:
private static final long[] THREE_CYCLES = new long[] { 100, 1000, 1000, 1000, 1000, 1000 };
public void longVibrate(View v)
{
vibrateMulti(THREE_CYCLES);
}
private void vibrateMulti(long[] cycles) {
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification();
notification.vibrate = cycles;
notificationManager.notify(0, notification);
}
And then in your xml file:
<button android:layout_height="wrap_content"
android:layout_width ="wrap_content"
android:onclick ="longVibrate"
android:text ="VibrateThrice">
</button>
That's the easiest way.
On Webpack 2 I tried all 12 devtool options. The following options link to the original file in the console and preserve line numbers. See the note below re: lines only.

Source Maps are simplified to a single mapping per line. This usually means a single mapping per statement (assuming you author is this way). This prevents you from debugging execution on statement level and from settings breakpoints on columns of a line. Combining with minimizing is not possible as minimizers usually only emit a single line.
REVISITING THIS
On a large project I find ... eval-source-map rebuild time is ~3.5s ... inline-source-map rebuild time is ~7s

Important things to note:
visible
is a variable (boolean) in the component which governs modal's visibility.show
and in
are bootstrap classes.Component

I know you have already accepted another answer, but I think the broader issue needs to addressed - programming style that is suitable to the current language.
Yes, 'initialization' isn't needed in Python, but what you are doing isn't initialization. It is just an incomplete and erroneous imitation of initialization as practiced in other languages. The important thing about initialization in static typed languages is that you specify the nature of the variables.
In Python, as in other languages, you do need to give variables values before you use them. But giving them values at the start of the function isn't important, and even wrong if the values you give have nothing to do with values they receive later. That isn't 'initialization', it's 'reuse'.
I'll make some notes and corrections to your code:
def main():
# doc to define the function
# proper Python indentation
# document significant variables, especially inputs and outputs
# grade_1, grade_2, grade_3, average - id these
# year - id this
# fName, lName, ID, converted_ID
infile = open("studentinfo.txt", "r")
# you didn't 'intialize' this variable
data = infile.read()
# nor this
fName, lName, ID, year = data.split(",")
# this will produce an error if the file does not have the right number of strings
# 'year' is now a string, even though you 'initialized' it as 0
year = int(year)
# now 'year' is an integer
# a language that requires initialization would have raised an error
# over this switch in type of this variable.
# Prompt the user for three test scores
grades = eval(input("Enter the three test scores separated by a comma: "))
# 'eval' ouch!
# you could have handled the input just like you did the file input.
grade_1, grade_2, grade_3 = grades
# this would work only if the user gave you an 'iterable' with 3 values
# eval() doesn't ensure that it is an iterable
# and it does not ensure that the values are numbers.
# What would happen with this user input: "'one','two','three',4"?
# Create a username
uName = (lName[:4] + fName[:2] + str(year)).lower()
converted_id = ID[:3] + "-" + ID[3:5] + "-" + ID[5:]
# earlier you 'initialized' converted_ID
# initialization in a static typed language would have caught this typo
# pseudo-initialization in Python does not catch typos
....
\usepackage{array}
in the preamble
then this:
\begin{tabular}{| >{\centering\arraybackslash}m{1in} | >{\centering\arraybackslash}m{1in} |}
note that the "m" for fixed with column is provided by the array package, and will give you vertical centering (if you don't want this just go back to "p"
You can get some inspiration by reading an entrypoint.sh
script written by the contributors from MySQL that checks whether the specified variables were set.
As the script shows, you can pipe them with -a
, e.g.:
if [ -z "$MYSQL_ROOT_PASSWORD" -a -z "$MYSQL_ALLOW_EMPTY_PASSWORD" -a -z "$MYSQL_RANDOM_ROOT_PASSWORD" ]; then
...
fi
You could build a Column/Row with Flexible or Expanded children that have flex values that add up to the percentages you want.
You may also find the AspectRatio widget useful.
For updating an href value, for example, I would do something like:
<a href="#myModal" data-toggle="modal" data-url="http://example.com">Show modal</a>
$('#myModal').on('show.bs.modal', function (e) {
var url = $(e.relatedTarget).data('url');
$(e.currentTarget).find('.any-class').attr("href", "url");
})
You can do this is just 3 simple step that i used.
1) make new branch where you want to commit you recent update.
git branch <branch name>
2) Find Recent Commit Id for commit on new branch.
git log
3) Copy that commit id note that Most Recent commit list take place on top. so you can find your commit. you also find this via message.
git cherry-pick d34bcef232f6c...
you can also provide some rang of commit id.
git cherry-pick d34bcef...86d2aec
Now your job done. If you picked correct id and correct branch then you will success. So before do this be careful. else another problem can occur.
Now you can push your code
git push

I got same problem. So I looked into the axios document. I found it. you can do it like this. this is easiest way. and super simple.
https://www.npmjs.com/package/axios#using-applicationx-www-form-urlencoded-format
var params = new URLSearchParams();
params.append('param1', 'value1');
params.append('param2', 'value2');
axios.post('/foo', params);
You can use .then,.catch.
Others have mentioned the relevel
command which is the best solution if you want to change the base level for all analyses on your data (or are willing to live with changing the data).
If you don't want to change the data (this is a one time change, but in the future you want the default behavior again), then you can use a combination of the C
(note uppercase) function to set contrasts and the contr.treatments
function with the base argument for choosing which level you want to be the baseline.
For example:
lm( Sepal.Width ~ C(Species,contr.treatment(3, base=2)), data=iris )
A jar file is simply a file containing a collection of java files. To make a jar file executable, you need to specify where the main
Class is in the jar file. Example code would be as follows.
public class JarExample {
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
// your logic here
}
});
}
}
Compile your classes. To make a jar, you also need to create a Manifest File (MANIFEST.MF
). For example,
Manifest-Version: 1.0
Main-Class: JarExample
Place the compiled output class files (JarExample.class,JarExample$1.class) and the manifest file in the same folder. In the command prompt, go to the folder where your files placed, and create the jar using jar command. For example (if you name your manifest file as jexample.mf)
jar cfm jarexample.jar jexample.mf *.class
It will create executable jarexample.jar.
grep -A 10000000 'TERMINATE' file
None of these answers ended up working for my Git credential issue. Here is what did work if anyone needs it (I'm using Git 1.9 on Windows 8.1).
To update your credentials, go to Control Panel → Credential Manager → Generic Credentials. Find the credentials related to your Git account and edit them to use the updated password.
Reference: How to update your Git credentials on Windows
Note that to use the Windows Credential Manager for Git you need to configure the credential helper like so:
git config --global credential.helper wincred
If you have multiple GitHub accounts that you use for different repositories, then you should configure credentials to use the full repository path (rather than just the domain, which is the default):
git config --global credential.useHttpPath true
None of the answers above really seems to answer the problem posed. I know this is an old thread, but I think this problem is a lot simpler than everyone is making it:
class tee_err(object):
def __init__(self):
self.errout = sys.stderr
sys.stderr = self
self.log = 'logfile.log'
log = open(self.log,'w')
log.close()
def write(self, line):
log = open(self.log,'a')
log.write(line)
log.close()
self.errout.write(line)
Now this will repeat everything to the normal sys.stderr handler and your file. Create another class tee_out
for sys.stdout
.
As of rev 17 of the Android Developer Tools, the correct way to add a library jar when.using the tools and Eclipse is to create a directory called libs
on the same level as your src
and assets
directories and then drop the jar in there. Nothing else.required, the tools take care of all the rest for you automatically.
Swift 3:
if let jsonString = styleDictionary as? String {
let objectData = jsonString.data(using: String.Encoding.utf8)
do {
let json = try JSONSerialization.jsonObject(with: objectData!, options: JSONSerialization.ReadingOptions.mutableContainers)
print(String(describing: json))
} catch {
// Handle error
print(error)
}
}
Both or
and ||
evaluate to true if either operand is true. They evaluate their second operand only if the first is false.
As with and
, the only difference between or
and ||
is their precedence.
Just to make life interesting, and
and or
have the same precedence, while &&
has a higher precedence than ||
.
You can include JQuery using any of the following:
<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
- http://code.jquery.com/jquery-latest.min.js (never use this link on production server)
Your code placement can look something like this
```
<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
<script>
$(document).ready(function(){
$('input[type=radio]').change(function() {
$('input[type=radio]').each(function(index) {
$(this).closest('tr').removeClass('selected');
});
$(this).closest('tr').addClass('selected');
});
});
</script>
```
Because your program now contains two copies of the foo
function, once inside foo.cpp and once inside main.cpp
Think of #include as an instruction to the compiler to copy/paste the contents of that file into your code, so you'll end up with a processed main.cpp that looks like this
#include <iostream> // actually you'll get the contents of the iostream header here, but I'm not going to include it!
int foo(int a){
return ++a;
}
int main(int argc, char *argv[])
{
int x=42;
std::cout << x <<std::endl;
std::cout << foo(x) << std::endl;
return 0;
}
and foo.cpp
int foo(int a){
return ++a;
}
hence the multiple definition error
.focus()
and then .blur()
something else arbitrary on your page. Since only one element can have the focus, it is transferred to that element and then removed.

For Python 3ers
Try updating. I had this exact same problem and tried Chases' answer, however no success. The quickest way to refactor this is to update your Python Minor / Patch version if possible. I noticed that I was running 3.5.1 and updated to 3.5.2. Pyvenv once again works.
You need mask
:
sample['PR'] = sample['PR'].mask(sample['PR'] < 90, np.nan)
Another solution with loc
and boolean indexing
:
sample.loc[sample['PR'] < 90, 'PR'] = np.nan
Sample:
import pandas as pd
import numpy as np
sample = pd.DataFrame({'PR':[10,100,40] })
print (sample)
PR
0 10
1 100
2 40
sample['PR'] = sample['PR'].mask(sample['PR'] < 90, np.nan)
print (sample)
PR
0 NaN
1 100.0
2 NaN
sample.loc[sample['PR'] < 90, 'PR'] = np.nan
print (sample)
PR
0 NaN
1 100.0
2 NaN
EDIT:
Solution with apply
:
sample['PR'] = sample['PR'].apply(lambda x: np.nan if x < 90 else x)
Timings len(df)=300k
:
sample = pd.concat([sample]*100000).reset_index(drop=True)
In [853]: %timeit sample['PR'].apply(lambda x: np.nan if x < 90 else x)
10 loops, best of 3: 102 ms per loop
In [854]: %timeit sample['PR'].mask(sample['PR'] < 90, np.nan)
The slowest run took 4.28 times longer than the fastest. This could mean that an intermediate result is being cached.
100 loops, best of 3: 3.71 ms per loop

I had the same problem on Windows 7 64-bit Pro. I adjusted network adapters binding using Control panel but nothing changed. Also metrics where showing that Win should use Ethernet adapter as primary, but it didn't.
Then a tried to uninstall Ethernet adapter driver and then install it again (without restart) and then I checked metrics for sure.
After this, Windows started prioritize Ethernet adapter.
If you use git and already have the tpope's plugin fugitive.vim then simply:
:Gmove newname
This will:
If your file was not yet added to a git repo then first add it:
:Gwrite
Find the location of the .bash_profile
file and enter the following into the file:
setterm -blength 0
Which will set the amount of time the beep happens to 0 and thus no beep.
Note that neither DBCC DROPCLEANBUFFERS;
nor DBCC FREEPROCCACHE;
is supported in SQL Azure / SQL Data Warehouse.
However, if you need to reset the plan cache in SQL Azure, you can alter one of the tables in the query (for instance, just add then remove a column), this will have the side-effect of removing the plan from the cache.
I personally do this as a way of testing query performance without having to deal with cached plans.
C# 6.0 Edit:
With C# 6.0 we can now have a succinct, cast-free version of the orignal method:
string s = myObj?.ToString() ?? "";
Or even using interpolation:
string s = $"{myObj}";
Original Answer:
string s = (myObj ?? String.Empty).ToString();
or
string s = (myObjc ?? "").ToString()
to be even more concise.
Unfortunately, as has been pointed out you'll often need a cast on either side to make this work with non String or Object types:
string s = (myObjc ?? (Object)"").ToString()
string s = ((Object)myObjc ?? "").ToString()
Therefore, while it maybe appears elegant, the cast is almost always necessary and is not that succinct in practice.
As suggested elsewhere, I recommend maybe using an extension method to make this cleaner:
public static string ToStringNullSafe(this object value)
{
return (value ?? string.Empty).ToString();
}
Hope this will help little more :-
var string = "123456789"
If you want a substring after some particular index.
var indexStart = string.index(after: string.startIndex )// you can use any index in place of startIndex
var strIndexStart = String (string[indexStart...])//23456789
If you want a substring after removing some string at the end.
var indexEnd = string.index(before: string.endIndex)
var strIndexEnd = String (string[..<indexEnd])//12345678
you can also create indexes with the following code :-
var indexWithOffset = string.index(string.startIndex, offsetBy: 4)
I don't believe that there is a formal limit here, and I'm pretty sure there isn't any hard limit specified in the RFC either, as you found.
I think that some pretty common limitations for subject lines in general (not just e-mail) are:
Obviously, you want to come up with something that is reasonable. If you're writing an e-mail client, you may want to go with something like 256 characters, and obviously test thoroughly against big commercial servers out there to make sure they serve your mail correctly.
Hope this helps!
I was having a problem with ASP.NET MVC 5 where CheckBoxFor would not check my checkboxes on server-side validation failure even though my model clearly had the value set to true. My Razor markup/code looked like:
@Html.CheckBoxFor(model => model.MyBoolValue, new { @class = "mySpecialClass" } )
To get this to work, I had to change this to:
@{
var checkboxAttributes = Model.MyBoolValue ?
(object) new { @class = "mySpecialClass", @checked = "checked" } :
(object) new { @class = "mySpecialClass" };
}
@Html.CheckBox("MyBoolValue", checkboxAttributes)

point = c(1,2,3,4,5)
if we want to append a number 6 anywhere inside the vector then below command may come handy

new_var = append(point, 6 ,after = length(point))
ii) columns of a table
new_var = append(point, 6 ,after = length(mtcars$mpg))
The command append
takes three arguments:

As I see in your code, it seems you are following an old documentation/tutorial about OOP in PHP based on PHP4 (OOP wasn't supported but adapted somehow to be used in a simple ways), since PHP5 an official support was added and the notation has been changed from what it was.
Please see this code review here:
<?php
class my_class{
public $my_value = array();
function __construct( $value ) { // the constructor name is __construct instead of the class name
$this->my_value[] = $value;
}
function set_value ($value){
// Error occurred from here as Undefined variable: my_value
$this->my_value = $value; // remove the $ sign
}
}
$a = new my_class ('a');
$a->my_value[] = 'b';
$a->set_value ('c'); // your array variable here will be replaced by a simple string
// $a->my_class('d'); // you can call this if you mean calling the contructor
// at this stage you can't loop on the variable since it have been replaced by a simple string ('c')
foreach ($a->my_value as &$value) { // look for foreach samples to know how to use it well
echo $value;
}
?>

I was just trying to make sense of it again myself. I found that the following helps!
• Think of the else
as being paired with the if
inside the loop (instead of with the for
) - if condition is met then break the loop, else do this - except it's one else
paired with multiple if
s!
• If no if
s were satisfied at all, then do the else
.
• The multiple if
s can also actually be thought of as if
-elif
s!
searchfile = open("file.txt", "r")
for line in searchfile:
if "searchphrase" in line: print line
searchfile.close()
To print out multiple lines (in a simple way)
f = open("file.txt", "r")
searchlines = f.readlines()
f.close()
for i, line in enumerate(searchlines):
if "searchphrase" in line:
for l in searchlines[i:i+3]: print l,
print
The comma in print l,
prevents extra spaces from appearing in the output; the trailing print statement demarcates results from different lines.
Or better yet (stealing back from Mark Ransom):
with open("file.txt", "r") as f:
searchlines = f.readlines()
for i, line in enumerate(searchlines):
if "searchphrase" in line:
for l in searchlines[i:i+3]: print l,
print

You can't directly get an iterator for an array.
But you can use a List, backed by your array, and get an ierator on this list. For that, your array must be an Integer array (instead of an int array):
Integer[] arr={1,2,3};
List<Integer> arrAsList = Arrays.asList(arr);
Iterator<Integer> iter = arrAsList.iterator();
Note: it is only theory. You can get an iterator like this, but I discourage you to do so. Performances are not good compared to a direct iteration on the array with the "extended for syntax".
Note 2: a list construct with this method doesn't support all methods (since the list is backed by the array which have a fixed size). For example, "remove" method of your iterator will result in an exception.
An old question but deserves an update as now there is a way.
The correct CSS based answer is to use object-fit: cover
, which works like background-size: cover
. Positioning would be taken care of by object-position
attribute, which defaults to centering.
But there is no support for it in any IE / Edge browsers, or Android < 4.4.4. Also, object-position
is not supported by Safari, iOS or OSX. Polyfills do exist, object-fit-images seems to give best support.
For more details on how the property works, see CSS Tricks article on object-fit
for explanation and demo.
I think the problem is that you load
isfar
data.frame but you overwrite it by value returned by load
.
Try either:
load("C:/Users/isfar.RData")
head(isfar)
Or more general way
load("C:/Users/isfar.RData", ex <- new.env())
ls.str(ex)
Just add the function reference to the $scope in the controller:
for example if you want the function MyFunction to work in ng-click just add to the controller:
app.controller("MyController", ["$scope", function($scope) {
$scope.MyFunction = MyFunction;
}]);
Update: In an effort to answer my own question, here is what I've been able to uncover so far. If anyone else out there has something, I'd still be interested to find out more.

As a summary, I would describe the wider impact of the repository pattern. It allows all of your code to use objects without having to know how the objects are persisted. All of the knowledge of persistence, including mapping from tables to objects, is safely contained in the repository.
Very often, you will find SQL queries scattered in the codebase and when you come to add a column to a table you have to search code files to try and find usages of a table. The impact of the change is far-reaching.
With the repository pattern, you would only need to change one object and one repository. The impact is very small.
Perhaps it would help to think about why you would use the repository pattern. Here are some reasons:
You have a single place to make changes to your data access
You have a single place responsible for a set of tables (usually)
It is easy to replace a repository with a fake implementation for testing - so you don't need to have a database available to your unit tests
There are other benefits too, for example, if you were using MySQL and wanted to switch to SQL Server - but I have never actually seen this in practice!
You can convert String to Timestamp:
String inDate = "01-01-1990"
DateFormat df = new SimpleDateFormat("MM-dd-yyyy");
Timestamp ts = new Timestamp(((java.util.Date)df.parse(inDate)).getTime());
I have taken three Views. In the first view I set full (no alpha) color, on the second view I set half (0.5 alpha) color, and on the third view I set light color (0.2 alpha).
You can set any color and get color with alpha by using the below code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools = "http://schemas.android.com/tools"
android:layout_width = "match_parent"
android:layout_height = "match_parent"
android:gravity = "center"
android:orientation = "vertical"
tools:context = "com.example.temp.MainActivity" >
<View
android:id = "@+id/fullColorView"
android:layout_width = "100dip"
android:layout_height = "100dip" />
<View
android:id = "@+id/halfalphaColorView"
android:layout_width = "100dip"
android:layout_height = "100dip"
android:layout_marginTop = "20dip" />
<View
android:id = "@+id/alphaColorView"
android:layout_width = "100dip"
android:layout_height = "100dip"
android:layout_marginTop = "20dip" />
</LinearLayout>
public class MainActivity extends Activity {
private View fullColorView, halfalphaColorView, alphaColorView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fullColorView = (View)findViewById(R.id.fullColorView);
halfalphaColorView = (View)findViewById(R.id.halfalphaColorView);
alphaColorView = (View)findViewById(R.id.alphaColorView);
fullColorView.setBackgroundColor(Color.BLUE);
halfalphaColorView.setBackgroundColor(getColorWithAlpha(Color.BLUE, 0.5f));
alphaColorView.setBackgroundColor(getColorWithAlpha(Color.BLUE, 0.2f));
}
private int getColorWithAlpha(int color, float ratio) {
int newColor = 0;
int alpha = Math.round(Color.alpha(color) * ratio);
int r = Color.red(color);
int g = Color.green(color);
int b = Color.blue(color);
newColor = Color.argb(alpha, r, g, b);
return newColor;
}
}
Kotlin version:
private fun getColorWithAlpha(color: Int, ratio: Float): Int {
return Color.argb(Math.round(Color.alpha(color) * ratio), Color.red(color), Color.green(color), Color.blue(color))
}
Done
This is not only a 'newbie' scenario. I just ran across this compiler message (GCC 5.4) when refactoring a class to remove some constructor parameters. I forgot to update both the declaration and definition, and the compiler spit out this unintuitive error.
The bottom line seems to be this: If the compiler can't match the definition's signature to the declaration's signature it thinks the definition is not a constructor and then doesn't know how to parse the code and displays this error. Which is also what happened for the OP: std::string
is not the same type as string
so the declaration's signature differed from the definition's and this message was spit out.
As a side note, it would be nice if the compiler looked for almost-matching constructor signatures and upon finding one suggested that the parameters didn't match rather than giving this message.
string.matches("^\\W*$");
should do what you want, but it does not include whitespace. string.matches("^(?:\\W|\\s)*$");
does match whitespace as well.
Look in the Cmakelists.txt if you find ARM you need to install C++ for ARM
It's these packages:
C++ Universal Windows Platform for ARM64 "Not Required"
Visual C++ Compilers and libraries for ARM "Not Required"
Visual C++ Compilers and libraries for ARM64 "Very Likely Required"
Required for finding Threads on ARM
enable_language(C)
enable_language(CXX)
Then the problems
No CMAKE_C_COMPILER could be found.
No CMAKE_CXX_COMPILER could be found.
Might disappear unless you specify c compiler like clang, and maybe installing clang will work in other favour.
You can with optional remove in cmakelists.txt both with # before enable_language if you are not compiling for ARM.
I'm surprised no one has mentioned dnSpy. dnSpy is a debugger and .NET assembly editor. You can use it to edit and debug assemblies even if you don't have any source code available.
Main features:
It is open source and one of most widely used reverse engineering tool for dot net.
You will want to set the MdiParent
property of your new form to the name of the MDI parent form, as follows:
dim form as new yourform
form.show()
form.MdiParent = nameParent

Well, It's a bit late for this but I've just started learning Qt and maybe this could help somebody out there:
If you're using Qt Creator then when you've started creating the project you were asked to choose a kit to be used with your project, Let's say you chose Desktop Qt <version-here> MinGW 64-bit
. For Qt 5, If you opened the Qt folder of your installation, you'll find a folder with the version of Qt installed as its name inside it, here you can find the kits you can choose from.
You can go to /PATH/FOR/Qt/mingw<version>_64/include
and here you'll find all the includes you can use in your program, just search for QApplication
and you'll find it inside the folder QtWidgets
, So you can use #include <QtWidgets/QApplication>
since the path starts from the include
folder.
The same goes for other headers if you're stuck with any and for other kits.
Note: "all the includes you can use" doesn't mean these are the only ones you can use, If you include iostream
for example then the compiler will include it from /PATH/FOR/Qt/Tools/mingw<version>_64/lib/gcc/x86_64-w64-mingw32/7.3.0/include/c++/iostream
When you push to a remote and you use the --set-upstream
flag git sets the branch you are pushing to as the remote tracking branch of the branch you are pushing.
Adding a remote tracking branch means that git then knows what you want to do when you git fetch
, git pull
or git push
in future. It assumes that you want to keep the local branch and the remote branch it is tracking in sync and does the appropriate thing to achieve this.
You could achieve the same thing with git branch --set-upstream-to
or git checkout --track
. See the git help pages on tracking branches for more information.
