If you want to use the custom imageView, I suggest you use this one
View look perfect and dont't use any nine path image
The simple answer is that you can't. box-shadow applies to the whole element only. You could use a different approach and use ::before in CSS to insert an 1-pixel high element into header nav and set the box-shadow on that instead.
I know this is stupidly hacky,
but if you want to support under v21, here are my achievements.

CSS3 has a box-shadow
property. Vendor prefixes are required at the moment for maximum browser compatibility.
div.box-shadow {
-webkit-box-shadow: 2px 2px 4px 1px #fff;
box-shadow: 2px 2px 4px 1px #fff;
}
There is a generator available at css3please.
With Python 3.7 I could do this:
>>> myDic={10: 'b', 3:'a', 5:'c'}
>>> sortDic = sorted(myDic.items())
>>> print(dict(sortDic))
{3:'a', 5:'c', 10: 'b'}
If you want a list of tuples:
>>> myDic={10: 'b', 3:'a', 5:'c'}
>>> sortDic = sorted(myDic.items())
>>> print(sortDic)
[(3, 'a'), (5, 'c'), (10, 'b')]

Try this and replace '[' & ']' with your string

These are the two properties JAXB is looking at.
public java.util.List testjaxp.ModeleREP.getTimeSeries()
and
protected java.util.List testjaxp.ModeleREP.timeSeries
This can be avoided by using JAXB annotation at get method just like mentioned below.
@XmlElement(name="TimeSeries"))
public java.util.List testjaxp.ModeleREP.getTimeSeries()
This solution will avoid recursion problems when using [...target] or {...target}
function shallowClone(target) {
if (typeof a == 'array') return [...target]
if (typeof a == 'object') return {...target}
return target
}
/* set skipRecursion to avoid throwing an exception on recursive references */
/* no need to specify refs, or path -- they are used interally */
function deepClone(target, skipRecursion, refs, path) {
if (!refs) refs = []
if (!path) path = ''
if (refs.indexOf(target) > -1) {
if (skipRecursion) return null
throw('Recursive reference at ' + path)
}
refs.push(target)
let clone = shallowCopy(target)
for (i in target) target[i] = deepClone(target, refs, path + '.' + i)
return clone
}
The best way to add different objects into same container is to use make_shared, vector, and range based loop and you will have a nice, clean and "readable" code!
typedef std::shared_ptr<gate> Ptr
vector<Ptr> myConatiner;
auto andGate = std::make_shared<ANDgate>();
myConatiner.push_back(andGate );
auto orGate= std::make_shared<ORgate>();
myConatiner.push_back(orGate);
for (auto& element : myConatiner)
element->run();
Heres a nice circle example:
drawable/circle.xml
:
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid
android:color="#ff87cefa"/>
<size
android:width="60dp"
android:height="60dp"/>
</shape>
And then the button in your xml file:
<Button
android:id="@+id/btn_send"
android:layout_width="60dp"
android:layout_height="60dp"
android:background="@drawable/circle"
android:text="OK"/>
I see you have a problem. Try building your app as Release and then check out your source codes build folder. It may be called Release-iphonesimulator. Inside here will be the app. Then go to (home folder)/Library/Application Support/iPhone Simulator (if you can't find it, try pressing Command - J and choosing arrange by name). Go to an OS that has apps in it in the iPhone sim, like 4.1. In that folder there should be an Applications folder. Open that, and there should be folders with random lettering. Pick any one, and replace it with the app you have. Make sure to delete anything in the little folders!
If it doesn't work, then I'm dumbfounded.
dt.Rows[1].ItemArray
gives you a copy of item arrays. When you modify it, you're not modifying the original.
You can simply do this:
dt.Rows[1][3] = "Value";
ItemArray property is used when you want to modify all row values.
ex.:
dt.Rows[1].ItemArray = newItemArray;
let arr1: boolean[] = [];
console.log(arr1[1]);
arr1.push(true);
First you need to create a Service
. In that Service
, create a class extending LocationListener
. For this, use the following code snippet of Service
:
public class LocationService extends Service {
public static final String BROADCAST_ACTION = "Hello World";
private static final int TWO_MINUTES = 1000 * 60 * 2;
public LocationManager locationManager;
public MyLocationListener listener;
public Location previousBestLocation = null;
Intent intent;
int counter = 0;
@Override
public void onCreate() {
super.onCreate();
intent = new Intent(BROADCAST_ACTION);
}
@Override
public void onStart(Intent intent, int startId) {
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
listener = new MyLocationListener();
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 4000, 0, (LocationListener) listener);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 4000, 0, listener);
}
@Override
public IBinder onBind(Intent intent)
{
return null;
}
protected boolean isBetterLocation(Location location, Location currentBestLocation) {
if (currentBestLocation == null) {
// A new location is always better than no location
return true;
}
// Check whether the new location fix is newer or older
long timeDelta = location.getTime() - currentBestLocation.getTime();
boolean isSignificantlyNewer = timeDelta > TWO_MINUTES;
boolean isSignificantlyOlder = timeDelta < -TWO_MINUTES;
boolean isNewer = timeDelta > 0;
// If it's been more than two minutes since the current location, use the new location
// because the user has likely moved
if (isSignificantlyNewer) {
return true;
// If the new location is more than two minutes older, it must be worse
} else if (isSignificantlyOlder) {
return false;
}
// Check whether the new location fix is more or less accurate
int accuracyDelta = (int) (location.getAccuracy() - currentBestLocation.getAccuracy());
boolean isLessAccurate = accuracyDelta > 0;
boolean isMoreAccurate = accuracyDelta < 0;
boolean isSignificantlyLessAccurate = accuracyDelta > 200;
// Check if the old and new location are from the same provider
boolean isFromSameProvider = isSameProvider(location.getProvider(),
currentBestLocation.getProvider());
// Determine location quality using a combination of timeliness and accuracy
if (isMoreAccurate) {
return true;
} else if (isNewer && !isLessAccurate) {
return true;
} else if (isNewer && !isSignificantlyLessAccurate && isFromSameProvider) {
return true;
}
return false;
}
/** Checks whether two providers are the same */
private boolean isSameProvider(String provider1, String provider2) {
if (provider1 == null) {
return provider2 == null;
}
return provider1.equals(provider2);
}
@Override
public void onDestroy() {
// handler.removeCallbacks(sendUpdatesToUI);
super.onDestroy();
Log.v("STOP_SERVICE", "DONE");
locationManager.removeUpdates(listener);
}
public static Thread performOnBackgroundThread(final Runnable runnable) {
final Thread t = new Thread() {
@Override
public void run() {
try {
runnable.run();
} finally {
}
}
};
t.start();
return t;
}
public class MyLocationListener implements LocationListener
{
public void onLocationChanged(final Location loc)
{
Log.i("*****", "Location changed");
if(isBetterLocation(loc, previousBestLocation)) {
loc.getLatitude();
loc.getLongitude();
intent.putExtra("Latitude", loc.getLatitude());
intent.putExtra("Longitude", loc.getLongitude());
intent.putExtra("Provider", loc.getProvider());
sendBroadcast(intent);
}
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
public void onProviderDisabled(String provider)
{
Toast.makeText( getApplicationContext(), "Gps Disabled", Toast.LENGTH_SHORT ).show();
}
public void onProviderEnabled(String provider)
{
Toast.makeText( getApplicationContext(), "Gps Enabled", Toast.LENGTH_SHORT).show();
}
}
Add this Service
any where in your project, the way you want! :)
Typically one would use one (or more) image tags, maybe in combination with setting div background images in css to act as the submit button. The actual submit would be done in javascript on the click event.
A tutorial on the subject.
You will have to save the relationship on the server side. The value is the only part that is transmitted when the form is posted. You could do something nasty like...
<option value="2|Dog">Dog</option>
Then split the result apart if you really wanted to, but that is an ugly hack and a waste of bandwidth assuming the numbers are truly unique and have a one to one relationship with the text.
The best way would be to create an array, and loop over the array to create the HTML. Once the form is posted you can use the value to look up the text in that same array.
<?php
function getTextBetweenTags($string, $tagname) {
$pattern = "/<$tagname ?.*>(.*)<\/$tagname>/";
preg_match($pattern, $string, $matches);
return $matches[1];
}
$str = '<textformat leading="2"><p align="left"><font size="10">get me</font></p></textformat>';
$txt = getTextBetweenTags($str, "font");
echo $txt;
?>
That should do the trick
In a project we had a problem so that we had to revert back to a certain commit. We made it with the following command successfully:
git reset --hard <commitID>
Note:
=""
is a blank cell) without a need to use data
twice. The solution for goolge-spreadhseet: =ARRAYFORMULA(SUM(IFERROR(IF(data="",0,1),1)))
. For excel ={SUM(IFERROR(IF(data="",0,1),1))}
should work (press Ctrl+Shift+Enter in the formula).It is safe to store your token in localStorage as long as you encrypt it. Below is a compressed code snippet showing one of many ways you can do it.
import SimpleCrypto from 'simple-crypto-js';
const saveToken = (token = '') => {
const encryptInit = new SimpleCrypto('PRIVATE_KEY_STORED_IN_ENV_FILE');
const encryptedToken = encryptInit.encrypt(token);
localStorage.setItem('token', encryptedToken);
}
Then, before using your token decrypt it using PRIVATE_KEY_STORED_IN_ENV_FILE
You can use IN operator as below
select * from dbo.books where isbn IN
(select isbn from dbo.lending where lended_date between @fdate and @tdate)
You can use the new js spread operator if using es6:
var json1 = [{id:1, name: 'xxx'}]_x000D_
var json2 = [{id:2, name: 'xyz'}]_x000D_
var finalObj = [...json1, ...json2]_x000D_
_x000D_
console.log(finalObj)
_x000D_
Practical example:
Imagine that you are modelling something like an I2C bus (signals called SCL
for clock and SDA
for data), where the bus is tri-state and both nets have a weak pull-up. Your testbench should model the pull-up resistor on the PCB with a value of 'H'.
scl <= 'H'; -- Testbench resistor pullup
Your I2C master or slave devices can drive the bus to '1' or '0' or leave it alone by assigning a 'Z'
Assigning a '1' to the SCL net will cause an event to happen, because the value of SCL changed.
If you have a line of code that relies on (scl'event and scl =
'1')
, then you'll get a false trigger.
If you have a line of code that relies on rising_edge(scl)
, then
you won't get a false trigger.
Continuing the example: you assign a '0' to SCL, then assign a 'Z'. The SCL net goes to '0', then back to 'H'.
Here, going from '1' to '0' isn't triggering either case, but going from '0' to 'H' will trigger a rising_edge(scl)
condition (correct), but the (scl'event and scl = '1')
case will miss it (incorrect).
General Recommenation:
Use rising_edge(clk)
and falling_edge(clk)
instead of clk'event
for all code.
Are you sure you need a regex? It seems that you only need to know if a word is present in a string, so you can do:
>>> line = 'This,is,a,sample,string'
>>> "sample" in line
True
A variation on @AndrewKennan's answer I ended up using recently for types obtained at runtime:
if (serviceType.IsInstanceOfType(service))
{
// 'service' does implement the 'serviceType' type
}
The OP mentioned SCP, so here's that.
As others have pointed out, SFTP is a confusing since the upload syntax is completely different from the download syntax. It gets marginally easier to remember if you use the same form:
echo 'put LOCALPATH REMOTEPATH' | sftp USER@HOST
echo 'get REMOTEPATH LOCALPATH' | sftp USER@HOST
In reality, this is still a mess, and is why people still use "outdated" commands such as SCP:
scp USER@HOST:REMOTEPATH LOCALPATH
scp LOCALPATH USER@HOST:REMOTEPATH
SCP is secure but dated. It has some bugs that will never be fixed, namely crashing if the server's .bash_profile
emits a message. However, in terms of usability, the devs were years ahead.
This should work:
DECLARE db_cursor CURSOR FOR SELECT name, age, color FROM table;
DECLARE @myName VARCHAR(256);
DECLARE @myAge INT;
DECLARE @myFavoriteColor VARCHAR(40);
OPEN db_cursor;
FETCH NEXT FROM db_cursor INTO @myName, @myAge, @myFavoriteColor;
WHILE @@FETCH_STATUS = 0
BEGIN
--Do stuff with scalar values
FETCH NEXT FROM db_cursor INTO @myName, @myAge, @myFavoriteColor;
END;
CLOSE db_cursor;
DEALLOCATE db_cursor;
The pixel width and height of your page will depend on orientation as well as the meta viewport tag, if specified. Here are the results of running jquery's $(window).width() and $(window).height() on iPad 1 browser.
When page has no meta viewport tag:
When page has either of these two meta tags:

Easy Way:
[Flags]
public enum MyFlags {
None = 0,
Susan = 1,
Alice = 2,
Bob = 4,
Eve = 8
}
To set the flags use logical "or" operator |
:
MyFlags f = new MyFlags();
f = MyFlags.Alice | MyFlags.Bob;
And to check if a flag is included use HasFlag
:
if(f.HasFlag(MyFlags.Alice)) { /* true */}
if(f.HasFlag(MyFlags.Eve)) { /* false */}
Try this code:
HttpClient httpClient = new DefaultHttpClient();
try {
HttpPost request = new HttpPost("http://yoururl");
StringEntity params =new StringEntity("details={\"name\":\"myname\",\"age\":\"20\"} ");
request.addHeader("content-type", "application/json");
request.addHeader("Accept","application/json");
request.setEntity(params);
HttpResponse response = httpClient.execute(request);
// handle response here...
}catch (Exception ex) {
// handle exception here
} finally {
httpClient.getConnectionManager().shutdown();
}
sorry for late answer but may be my code may help u.
I placed 3 buttons on the winform surface. button1 & 2 will set different value and button3 will retrieve current value. so when run my code first add the reference System.configuration
and click on first button and then click on 3rd button to see what value has been set. next time again click on second & 3rd button to see again what value has been set after change.
so here is the code.
using System.Configuration;
private void button1_Click(object sender, EventArgs e)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
config.AppSettings.Settings.Remove("DBServerName");
config.AppSettings.Settings.Add("DBServerName", "FirstAddedValue1");
config.Save(ConfigurationSaveMode.Modified);
}
private void button2_Click(object sender, EventArgs e)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
config.AppSettings.Settings.Remove("DBServerName");
config.AppSettings.Settings.Add("DBServerName", "SecondAddedValue1");
config.Save(ConfigurationSaveMode.Modified);
}
private void button3_Click(object sender, EventArgs e)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
MessageBox.Show(config.AppSettings.Settings["DBServerName"].Value);
}
Google, no API needed:
$data = file_get_contents('http://picasaweb.google.com/data/entry/api/user/<USER_ID>?alt=json');
$d = json_decode($data);
$avatar = $d->{'entry'}->{'gphoto$thumbnail'}->{'$t'};
// Outputs example: https://lh3.googleusercontent.com/-2N6fRg5OFbM/AAAAAAAAAAI/AAAAAAAAADE/2-RmpExH6iU/s64-c/photo.jpg
CHANGE: the 64 in "s64" for the size
The main intention here is to send an ordered JSON object as response. We don't need javax.json.JsonObject to achieve that. We could create the ordered json as a string. First create a LinkedHashMap with all key value pairs in required order. Then generate the json in string as shown below. Its much easier with Java 8.
public Response getJSONResponse() {
Map<String, String> linkedHashMap = new LinkedHashMap<>();
linkedHashMap.put("A", "1");
linkedHashMap.put("B", "2");
linkedHashMap.put("C", "3");
String jsonStr = linkedHashMap.entrySet().stream()
.map(x -> "\"" + x.getKey() + "\":\"" + x.getValue() + "\"")
.collect(Collectors.joining(",", "{", "}"));
return Response.ok(jsonStr).build();
}
The response return by this function would be following:
{"A":"1","B":"2","C":"3"}

error example:
public class MaainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the view from activity_main.xml
setContentView(R.layout.activity_main);
}
}
correct example:just make sure that you written correct name of activity that is"main activity"
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the view from activity_main.xml
setContentView(R.layout.activity_main);
}
}
Forgot to relate to the first code snippet. I wouldn't use forEach
at all. Since you are collecting the elements of the Stream
into a List
, it would make more sense to end the Stream
processing with collect
. Then you would need peek
in order to set the ID.
List<Entry> updatedEntries =
entryList.stream()
.peek(e -> e.setTempId(tempId))
.collect (Collectors.toList());
For the second snippet, forEach
can execute multiple expressions, just like any lambda expression can :
entryList.forEach(entry -> {
if(entry.getA() == null){
printA();
}
if(entry.getB() == null){
printB();
}
if(entry.getC() == null){
printC();
}
});
However (looking at your commented attempt), you can't use filter in this scenario, since you will only process some of the entries (for example, the entries for which entry.getA() == null
) if you do.

I had the reverse use case of importing an existing repository from github to bitbucket.
Bitbucket offers an Import tool as well. The only necessary step is to add URL to repository.

Inspired by Daniel's code above and the fact that this is WAY! more interesting to me now then the actual work I have to do, i created a hopefully full-proof function to find the first blank row in a sheet. Improvements welcome! Otherwise, this is going to my library :) Hopefully others benefit as well.
Function firstBlankRow(ws As Worksheet) As Long
'returns the row # of the row after the last used row
'Or the first row with no data in it
Dim rngSearch As Range, cel As Range
With ws
Set rngSearch = .UsedRange.Columns(1).Find("") '-> does blank exist in the first column of usedRange
If Not rngSearch Is Nothing Then
Set rngSearch = .UsedRange.Columns(1).SpecialCells(xlCellTypeBlanks)
For Each cel In rngSearch
If Application.WorksheetFunction.CountA(cel.EntireRow) = 0 Then
firstBlankRow = cel.Row
Exit For
End If
Next
Else '-> no blanks in first column of used range
If Application.WorksheetFunction.CountA(Cells(.Rows.Count, 1).EntireRow) = 0 Then '-> is the last row of the sheet blank?
'-> yeap!, then no blank rows!
MsgBox "Whoa! All rows in sheet are used. No blank rows exist!"
Else
'-> okay, blank row exists
firstBlankRow = .UsedRange.SpecialCells(xlCellTypeBlanks).Row + 1
End If
End If
End With
End Function
Original Answer
To find the first blank in a sheet, replace this part of your code:
Cells(1, 1).Select
For Each Cell In ws.UsedRange.Cells
If Cell.Value = "" Then Cell = Num
MsgBox "Checking cell " & Cell & " for value."
Next
With this code:
With ws
Dim rngBlanks As Range, cel As Range
Set rngBlanks = Intersect(.UsedRange, .Columns(1)).Find("")
If Not rngBlanks Is Nothing Then '-> make sure blank cell exists in first column of usedrange
'-> find all blank rows in column A within the used range
Set rngBlanks = Intersect(.UsedRange, .Columns(1)).SpecialCells(xlCellTypeBlanks)
For Each cel In rngBlanks '-> loop through blanks in column A
'-> do a countA on the entire row, if it's 0, there is nothing in the row
If Application.WorksheetFunction.CountA(cel.EntireRow) = 0 Then
num = cel.Row
Exit For
End If
Next
Else
num = usedRange.SpecialCells(xlCellTypeLastCell).Offset(1).Row
End If
End With
The right way to do this is:
composer remove jenssegers/mongodb --update-with-dependencies
I must admit the flag here is not quite obvious as to what it will do.
composer remove jenssegers/mongodb
As of v1.0.0-beta2 --update-with-dependencies
is the default and is no longer required.
you need implements Parcelable in your ContactBean
class, I put one example for you:
public class ContactClass implements Parcelable {
private String id;
private String photo;
private String firstname;
private String lastname;
public ContactClass()
{
}
private ContactClass(Parcel in) {
firstname = in.readString();
lastname = in.readString();
photo = in.readString();
id = in.readString();
}
@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(firstname);
dest.writeString(lastname);
dest.writeString(photo);
dest.writeString(id);
}
public static final Parcelable.Creator<ContactClass> CREATOR = new Parcelable.Creator<ContactClass>() {
public ContactClass createFromParcel(Parcel in) {
return new ContactClass(in);
}
public ContactClass[] newArray(int size) {
return new ContactClass[size];
}
};
// all get , set method
}
and this get and set for your code:
Intent intent = new Intent(this,DisplayContact.class);
intent.putExtra("Contact_list", ContactLis);
startActivity(intent);
second class:
ArrayList<ContactClass> myList = getIntent().getParcelableExtra("Contact_list");
You can activate JVM's debugging capability when starting up the java
command with a special option:
java -agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=y -jar path/to/some/war/or/jar.jar
Starting up jar.jar
like that on the command line will:
server=y
) listening on port 8000 (address=8000
)Listening for transport dt_socket at address: 8000
to stdout
andsuspend=y
) until some debugger connects. The debugger acts as the client in this scenario.Common options for selecting a debugger are:
jar.jar
should begin executing.jdb -connect com.sun.jdi.SocketAttach:port=8000
I've had some problems sending emails from my gmail account too, which were due to several of the aforementioned situations. Here's a summary of how I got it working, and keeping it flexible at the same time:
<configuration>
<appSettings>
<add key="EnableSSLOnMail" value="True"/>
</appSettings>
<!-- other settings -->
...
<!-- system.net settings -->
<system.net>
<mailSettings>
<smtp from="[email protected]" deliveryMethod="Network">
<network
defaultCredentials="false"
host="smtp.gmail.com"
port="587"
password="stR0ngPassW0rd"
userName="[email protected]"
/>
<!-- When using .Net 4.0 (or later) add attribute: enableSsl="true" and you're all set-->
</smtp>
</mailSettings>
</system.net>
</configuration>
Add a Class to your project:
Imports System.Net.Mail
Public Class SSLMail
Public Shared Sub SendMail(ByVal e As System.Web.UI.WebControls.MailMessageEventArgs)
GetSmtpClient.Send(e.Message)
'Since the message is sent here, set cancel=true so the original SmtpClient will not try to send the message too:
e.Cancel = True
End Sub
Public Shared Sub SendMail(ByVal Msg As MailMessage)
GetSmtpClient.Send(Msg)
End Sub
Public Shared Function GetSmtpClient() As SmtpClient
Dim smtp As New Net.Mail.SmtpClient
'Read EnableSSL setting from web.config
smtp.EnableSsl = CBool(ConfigurationManager.AppSettings("EnableSSLOnMail"))
Return smtp
End Function
End Class
And now whenever you want to send emails all you need to do is call SSLMail.SendMail
:
e.g. in a Page with a PasswordRecovery control:
Partial Class RecoverPassword
Inherits System.Web.UI.Page
Protected Sub RecoverPwd_SendingMail(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.MailMessageEventArgs) Handles RecoverPwd.SendingMail
e.Message.Bcc.Add("[email protected]")
SSLMail.SendMail(e)
End Sub
End Class
Or anywhere in your code you can call:
SSLMail.SendMail(New system.Net.Mail.MailMessage("[email protected]","[email protected]", "Subject", "Body"})
I hope this helps anyone who runs into this post! (I used VB.NET but I think it's trivial to convert it to any .NET language.)
Use the SelectMany extension method
list = listOfList.SelectMany(x => x).ToList();
If you're using spring boot, just add an @Modifying annotation.
@Modifying
@Query
(value = "UPDATE user SET middleName = 'Mudd' WHERE id = 1", nativeQuery = true)
void updateMiddleName();
Python can do unexpected things when new objects are defined from existing ones. You stated in a comment above that your dataframe is defined along the lines of df = df_all.loc[df_all['issueid']==specific_id,:]
. In this case, df
is really just a stand-in for the rows stored in the df_all
object: a new object is NOT created in memory.
To avoid these issues altogether, I often have to remind myself to use the copy
module, which explicitly forces objects to be copied in memory so that methods called on the new objects are not applied to the source object. I had the same problem as you, and avoided it using the deepcopy
function.
In your case, this should get rid of the warning message:
from copy import deepcopy
df = deepcopy(df_all.loc[df_all['issueid']==specific_id,:])
df['industry'] = 'yyy'
EDIT: Also see David M.'s excellent comment below!
df = df_all.loc[df_all['issueid']==specific_id,:].copy()
df['industry'] = 'yyy'
Do a describe on dba_arguments, dba_errors, dba_procedures, dba_objects, dba_source, dba_object_size. Each of these has part of the pictures for looking at the procedures and functions.
Also the object_type in dba_objects for packages is 'PACKAGE' for the definition and 'PACKAGE BODY" for the body.
If you are comparing schemas on the same database then try:
select * from dba_objects
where schema_name = 'ASCHEMA'
and object_type in ( 'PROCEDURE', 'PACKAGE', 'FUNCTION', 'PACKAGE BODY' )
minus
select * from dba_objects
where schema_name = 'BSCHEMA'
and object_type in ( 'PROCEDURE', 'PACKAGE', 'FUNCTION', 'PACKAGE BODY' )
and switch around the orders of ASCHEMA and BSCHEMA.
If you also need to look at triggers and comparing other stuff between the schemas you should take a look at the Article on Ask Tom about comparing schemas
It appears the default setting for Adobe Reader X is for the toolbars not to be shown by default unless they are explicitly turned on by the user. And even when I turn them back on during a session, they don't show up automatically next time. As such, I suspect you have a preference set contrary to the default.
The state you desire, with the top and left toolbars not shown, is called "Read Mode". If you right-click on the document itself, and then click "Page Display Preferences" in the context menu that is shown, you'll be presented with the Adobe Reader Preferences dialog. (This is the same dialog you can access by opening the Adobe Reader application, and selecting "Preferences" from the "Edit" menu.) In the list shown in the left-hand column of the Preferences dialog, select "Internet". Finally, on the right, ensure that you have the "Display in Read Mode by default" box checked:
You can also turn off the toolbars temporarily by clicking the button at the right of the top toolbar that depicts arrows pointing to opposing corners:
Finally, if you have "Display in Read Mode by default" turned off, but want to instruct the page you're loading not to display the toolbars (i.e., override the user's current preferences), you can append the following to the URL:
#toolbar=0&navpanes=0
So, for example, the following code will disable both the top toolbar (called "toolbar") and the left-hand toolbar (called "navpane"). However, if the user knows the keyboard combination (F8, and perhaps other methods as well), they will still be able to turn them back on.
string url = @"http://www.domain.com/file.pdf#toolbar=0&navpanes=0";
this._WebBrowser.Navigate(url);

I also use Stefan Petre’s http://www.eyecon.ro/bootstrap-datepicker and it does not work with Bootstrap 3 without modification. Note that http://eternicode.github.io/bootstrap-datepicker/ is a fork of Stefan Petre's code.
You have to change your markup (the sample markup will not work) to use the new CSS and form grid layout in Bootstrap 3. Also, you have to modify some CSS and JavaScript in the actual bootstrap-datepicker implementation.
Here is my solution:
<div class="form-group row">
<div class="col-xs-8">
<label class="control-label">My Label</label>
<div class="input-group date" id="dp3" data-date="12-02-2012" data-date-format="mm-dd-yyyy">
<input class="form-control" type="text" readonly="" value="12-02-2012">
<span class="input-group-addon"><i class="glyphicon glyphicon-calendar"></i></span>
</div>
</div>
</div>
CSS changes in datepicker.css on lines 176-177:
.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {
Javascript change in datepicker-bootstrap.js on line 34:
this.component = this.element.is('.date') ? this.element.find('.input-group-addon') : false;
UPDATE
Using the newer code from http://eternicode.github.io/bootstrap-datepicker/ the changes are as follows:
CSS changes in datepicker.css on lines 446-447:
.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {
Javascript change in datepicker-bootstrap.js on line 46:
this.component = this.element.is('.date') ? this.element.find('.input-group-addon, .btn') : false;
Finally, the JavaScript to enable the datepicker (with some options):
$(".input-group.date").datepicker({ autoclose: true, todayHighlight: true });
Tested with Bootstrap 3.0 and JQuery 1.9.1. Note that this fork is better to use than the other as it is more feature rich, has localization support and auto-positions the datepicker based on the control position and window size, avoiding the picker going off the screen which was a problem with the older version.
The print statement will output an object to the user. A return statement will allow assigning the dictionary to a variable once the function is finished.
>>> def foo():
... print "Hello, world!"
...
>>> a = foo()
Hello, world!
>>> a
>>> def foo():
... return "Hello, world!"
...
>>> a = foo()
>>> a
'Hello, world!'
Or in the context of returning a dictionary:
>>> def foo():
... print {'a' : 1, 'b' : 2}
...
>>> a = foo()
{'a': 1, 'b': 2}
>>> a
>>> def foo():
... return {'a' : 1, 'b' : 2}
...
>>> a = foo()
>>> a
{'a': 1, 'b': 2}
(The statements where nothing is printed out after a line is executed means the last statement returned None)
display:unset sets it back to some initial setting, not to the previous "display" values
i just copied the previous display value (in my case display: flex;) again(after display non), and it overtried the display:none successfuly
(i used display:none for hiding elements for mobile and small screens)
If you're using IDLE, and the Norwegian keyboard makes Ctrl-[ a problem, you can change the key.
I tried putting in shift-Tab and that worked nicely.
Here is my answer that works just fine...
You should be able to get current Activity in this way... If you structure your app with a few Activities with many fragments and you want to keep track of what is your current Activity, it would take a lot of work though. My senario was I do have one Activity with multiple Fragments. So I can keep track of Current Activity through Application Object, which can store all of the current state of Global variables.
Here is a way. When you start your Activity, you store that Activity by Application.setCurrentActivity(getIntent()); This Application will store it. On your service class, you can simply do like Intent currentIntent = Application.getCurrentActivity(); getApplication().startActivity(currentIntent);
BigDecimal a = new BigDecimal("12345.0789");
a = a.divide(new BigDecimal("1"), 2, BigDecimal.ROUND_HALF_UP);
//Also check other rounding modes
System.out.println("a >> "+a.toPlainString()); //Returns 12345.08
Rank and Dense rank gives the rank in the partitioned dataset.
Rank() : It doesn't give you consecutive integer numbers.
Dense_rank() : It gives you consecutive integer numbers.
In above picture , the rank of 10008 zip is 2 by dense_rank() function and 24 by rank() function as it considers the row_number.
WARNING: contains sarcasm judiciously! YMMV...
Luigi's answer is complete and correct. This one is only to extend it a bit with an example of how you can gloriously overuse implicits, as it happens quite often in Scala projects. Actually so often, you can probably even find it in one of the "Best Practice" guides.
object HelloWorld {
case class Text(content: String)
case class Prefix(text: String)
implicit def String2Text(content: String)(implicit prefix: Prefix) = {
Text(prefix.text + " " + content)
}
def printText(text: Text): Unit = {
println(text.content)
}
def main(args: Array[String]): Unit = {
printText("World!")
}
// Best to hide this line somewhere below a pile of completely unrelated code.
// Better yet, import its package from another distant place.
implicit val prefixLOL = Prefix("Hello")
}

$conn = mysql_connect ("localhost:3306","root","");
$db = mysql_select_db ("database_name", $conn);
if(!$db) {
echo mysql_error();
}
$q = "SELECT image FROM table_name where id=4";

echo $row ["image"];
}
}else{

}
?>
sometimes problem may occures because of port number of mysql server is incoreect to avoid it just write port number with host name like this "localhost:3306"
in case if you have installed two mysql servers on same system then write port according to that
in order to display any data from database please make sure following steps
1.proper connection with sql
2.select database
3.write query
4.write correct table name inside the query
5.and last is traverse through data
The best practice for this situation. Use RETURNING … INTO
.
INSERT INTO teams VALUES (...) RETURNING id INTO last_id;
Note this is for PLPGSQL
I see three solutions to this:
Change the output encoding, so it will always output UTF-8. See e.g. Setting the correct encoding when piping stdout in Python, but I could not get these example to work.
Following example code makes the output aware of your target charset.
# -*- coding: utf-8 -*-
import sys
print sys.stdout.encoding
print u"Stöcker".encode(sys.stdout.encoding, errors='replace')
print u"????????".encode(sys.stdout.encoding, errors='replace')
This example properly replaces any non-printable character in my name with a question mark.
If you create a custom print function, e.g. called myprint
, using that mechanisms to encode output properly you can simply replace print with myprint
whereever necessary without making the whole code look ugly.
Reset the output encoding globally at the begin of the software:
The page http://www.macfreek.nl/memory/Encoding_of_Python_stdout has a good summary what to do to change output encoding. Especially the section "StreamWriter Wrapper around Stdout" is interesting. Essentially it says to change the I/O encoding function like this:
In Python 2:
if sys.stdout.encoding != 'cp850':
sys.stdout = codecs.getwriter('cp850')(sys.stdout, 'strict')
if sys.stderr.encoding != 'cp850':
sys.stderr = codecs.getwriter('cp850')(sys.stderr, 'strict')
In Python 3:
if sys.stdout.encoding != 'cp850':
sys.stdout = codecs.getwriter('cp850')(sys.stdout.buffer, 'strict')
if sys.stderr.encoding != 'cp850':
sys.stderr = codecs.getwriter('cp850')(sys.stderr.buffer, 'strict')
If used in CGI outputting HTML you can replace 'strict' by 'xmlcharrefreplace' to get HTML encoded tags for non-printable characters.
Feel free to modify the approaches, setting different encodings, .... Note that it still wont work to output non-specified data. So any data, input, texts must be correctly convertable into unicode:
# -*- coding: utf-8 -*-
import sys
import codecs
sys.stdout = codecs.getwriter("iso-8859-1")(sys.stdout, 'xmlcharrefreplace')
print u"Stöcker" # works
print "Stöcker".decode("utf-8") # works
print "Stöcker" # fails
I was facing similar problem and to my surprise the problem was in the version of Java. java.sql.DriverManager comes from rt.jar was unable to load my driver "COM.ibm.db2.jdbc.app.DB2Driver".
I upgraded from jdk 5 and jdk 6 and it worked.
Based on some of the above answers I created a MoneyTextWatcher which you'd use as follows:
priceEditText.addTextChangedListener(new MoneyTextWatcher(priceEditText));
and here's the class:
public class MoneyTextWatcher implements TextWatcher {
private final WeakReference<EditText> editTextWeakReference;
public MoneyTextWatcher(EditText editText) {
editTextWeakReference = new WeakReference<EditText>(editText);
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable editable) {
EditText editText = editTextWeakReference.get();
if (editText == null) return;
String s = editable.toString();
if (s.isEmpty()) return;
editText.removeTextChangedListener(this);
String cleanString = s.replaceAll("[$,.]", "");
BigDecimal parsed = new BigDecimal(cleanString).setScale(2, BigDecimal.ROUND_FLOOR).divide(new BigDecimal(100), BigDecimal.ROUND_FLOOR);
String formatted = NumberFormat.getCurrencyInstance().format(parsed);
editText.setText(formatted);
editText.setSelection(formatted.length());
editText.addTextChangedListener(this);
}
}
This worked for me:
image: {
flex: 1,
aspectRatio: 1.5,
resizeMode: 'contain',
}
aspectRatio is just width/height (my image is 45px wide x 30px high).
$("input").is(":not(':checked')"))
This is jquery 1.3, mind the ' and " signs!
Like this:
var myString = "19 51 2.108997";
var stringParts = myString.split(" ");
var html = "<span>" + stringParts[0] + " " + stringParts[1] + "</span> <span>" + stringParts[2] + "</span";
As mentioned several times above, 'self' is simply being used to keep a reference to 'this' prior to entering the funcition. Once in the function 'this' refers to something else.
One of my favorite parts about registers is using them as macros!
Let's say you are dealing with a tab-delimited value file as such:
ID Df %Dev Lambda
1 0 0.000000 0.313682
2 1 0.023113 0.304332
3 1 0.044869 0.295261
4 1 0.065347 0.286460
5 1 0.084623 0.277922
6 1 0.102767 0.269638
7 1 0.119845 0.261601
Now you decide that you need to add a percentage sign at the end of the %Dev field (starting from 2nd line). We'll make a simple macro in the (arbitrarily selected) m
register as follows:
Press: qm
: To start recording macro under m
register.
EE
: Go to the end of the 3rd column.
a
: Insert mode to append to the end of this column.
%
: Type the percent sign we want to add.
<ESC>
: Get back into command mode.
j0
: Go to beginning of next line.
q
: Stop recording macro
We can now just type @m
to run this macro on the current line. Furthermore, we can type @@
to repeat, or 100@m
to do this 100 times! Life's looking pretty good.
At this point you should be saying, "But what does this have to do with registers?"
Excellent point. Let's investigate what is in the contents of the m
register by typing "mp
. We then get the following:
EEa%<ESC>j0
At first this looks like you accidentally opened a binary file in notepad, but upon second glance, it's the exact sequence of characters in our macro!
You are a curious person, so let's do something interesting and edit this line of text to insert a !
instead of boring old %
.
EEa!<ESC>j0
Then let's yank this into the n
register by typing B"nyE
. Then, just for kicks, let's run the n
macro on a line of our data using @n
....
It added a !
.
Essentially, running a macro is like pressing the exact sequence of keys in that macro's register. If that isn't a cool register trick, I'll eat my hat.

When you do a cmp a,b
, the flags are set as if you had calculated a - b
.
Then the jmp
-type instructions check those flags to see if the jump should be made.
In other words, the first block of code you have (with my comments added):
cmp al,dl ; set flags based on the comparison
jg label1 ; then jump based on the flags
would jump to label1
if and only if al
was greater than dl
.
You're probably better off thinking of it as al > dl
but the two choices you have there are mathematically equivalent:
al > dl
al - dl > dl - dl (subtract dl from both sides)
al - dl > 0 (cancel the terms on the right hand side)
You need to be careful when using jg
inasmuch as it assumes your values were signed. So, if you compare the bytes 101 (101 in two's complement) with 200 (-56 in two's complement), the former will actually be greater. If that's not what was desired, you should use the equivalent unsigned comparison.
See here for more detail on jump selection, reproduced below for completeness. First the ones where signed-ness is not appropriate:
+--------+------------------------------+-------------+--------------------+
|Instr | Description | signed-ness | Flags |
+--------+------------------------------+-------------+--------------------+
| JO | Jump if overflow | | OF = 1 |
+--------+------------------------------+-------------+--------------------+
| JNO | Jump if not overflow | | OF = 0 |
+--------+------------------------------+-------------+--------------------+
| JS | Jump if sign | | SF = 1 |
+--------+------------------------------+-------------+--------------------+
| JNS | Jump if not sign | | SF = 0 |
+--------+------------------------------+-------------+--------------------+
| JE/ | Jump if equal | | ZF = 1 |
| JZ | Jump if zero | | |
+--------+------------------------------+-------------+--------------------+
| JNE/ | Jump if not equal | | ZF = 0 |
| JNZ | Jump if not zero | | |
+--------+------------------------------+-------------+--------------------+
| JP/ | Jump if parity | | PF = 1 |
| JPE | Jump if parity even | | |
+--------+------------------------------+-------------+--------------------+
| JNP/ | Jump if no parity | | PF = 0 |
| JPO | Jump if parity odd | | |
+--------+------------------------------+-------------+--------------------+
| JCXZ/ | Jump if CX is zero | | CX = 0 |
| JECXZ | Jump if ECX is zero | | ECX = 0 |
+--------+------------------------------+-------------+--------------------+
Then the unsigned ones:
+--------+------------------------------+-------------+--------------------+
|Instr | Description | signed-ness | Flags |
+--------+------------------------------+-------------+--------------------+
| JB/ | Jump if below | unsigned | CF = 1 |
| JNAE/ | Jump if not above or equal | | |
| JC | Jump if carry | | |
+--------+------------------------------+-------------+--------------------+
| JNB/ | Jump if not below | unsigned | CF = 0 |
| JAE/ | Jump if above or equal | | |

The constraint could be removed with syntax:
As of MySQL 8.0.19, ALTER TABLE permits more general (and SQL standard) syntax for dropping and altering existing constraints of any type, where the constraint type is determined from the constraint name:
ALTER TABLE tbl_name DROP CONSTRAINT symbol;
Example:
CREATE TABLE tab(id INT, CONSTRAINT unq_tab_id UNIQUE(id));
-- checking constraint name if autogenerated
SELECT * FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE TABLE_NAME = 'tab';
-- dropping constraint
ALTER TABLE tab DROP CONSTRAINT unq_tab_id;
How are you getting the value of "results"? Are you getting it via ResultSet.getDouble()? In that case, you can check ResultSet.wasNull()
.
This solution works using Bootstrap v2, however in TBS3 the class INLINE. I haven't figured out what is the equivalent class (if there is one) in TBS3.
This gentleman had a pretty good article of the differences between v2 and v3.

EDIT - use CSS to target the li
elements to solve your problem as below
{ display: inline-block; }
In my situation I was targeting the UL, instead of the LI
nav ul li { display: inline-block; }
The pdfrw
library can do this quite easily, assuming you don't need to preserve bookmarks and annotations, and your PDFs aren't encrypted. cat.py
is an example concatenation script, and subset.py
is an example page subsetting script.
The relevant part of the concatenation script -- assumes inputs
is a list of input filenames, and outfn
is an output file name:
from pdfrw import PdfReader, PdfWriter
writer = PdfWriter()
for inpfn in inputs:
writer.addpages(PdfReader(inpfn).pages)
writer.write(outfn)
As you can see from this, it would be pretty easy to leave out the last page, e.g. something like:
writer.addpages(PdfReader(inpfn).pages[:-1])
Disclaimer: I am the primary pdfrw
author.

For the first case you propose you can use: '[[:blank:]]+[A-Z0-9]+[[:blank:]]+', for example:
echo "The thing P1 must connect to the J236 thing in the Foo position" | grep -oE '[[:blank:]]+[A-Z0-9]+[[:blank:]]+'
In the second case maybe you need to use something else and not a regex, maybe a script with a dictionary of technical words...

Alternatively you can grant the user DROP_ANY_TABLE
privilege if need be and the procedure will run as is without the need for any alteration. Dangerous maybe but depends what you're doing :)
Encountered the same problem. For my case i was working behind a proxy.
My solution was
Modify the settings.xml file in the .m2 folder to add the proxy configuration.
proxy true http 172.23.182.63 4145
In eclipse Click update settings button. Menu: Windows>>Preferences>>Maven>>User Settings
After step 4 - eclipse took a few minutes downloading files and project refreshed successfully.
sudo su -
gedit ~/.bashrc
export PATH=${PATH}:/your path
export PATH=${PATH}:/your path
export PATH=${PATH}:/opt/workspace/android/android-sdk-linux/tools
export PATH=${PATH}:/opt/workspace/android/android-sdk-linux/platform-tools
Try add this command in your build.gradle
So for running configure that shape:
Yes, that's possible - you can use INSERT ... ON DUPLICATE KEY UPDATE.
Using your example:
INSERT INTO table (id,Col1,Col2) VALUES (1,1,1),(2,2,3),(3,9,3),(4,10,12)
ON DUPLICATE KEY UPDATE Col1=VALUES(Col1),Col2=VALUES(Col2);
I found this approach direct and useful.
CONVERT(VARCHAR(10), CONVERT(MONEY, fieldname)) AS PRICE
You can parse the pom file with JDOM (http://www.jdom.org/).
move c:\sourcefolder c:\targetfolder
will work, but you will end up with a structure like this:
c:\targetfolder\sourcefolder\[all the subfolders & files]
If you want to move just the contents of one folder to another, then this should do it:
SET src_folder=c:\srcfold
SET tar_folder=c:\tarfold
for /f %%a IN ('dir "%src_folder%" /b') do move "%src_folder%\%%a" "%tar_folder%\"
pause
Using toggle instead of hide, solved my problem
If you don't want to convert.Just use;
bool _status = status == "1" ? true : false;
Perhaps you will return the values as you want.
Funnily, closing Xcode and reopening it might also be enough.
I needed something like that and the solution I gave with the help of jquery is this:
<textarea class="textlimited" data-textcounterid="counter1" maxlength="30">text</textarea>
<span class='textcounter' id="counter1"></span>
With this script:
// the selector below will catch the keyup events of elements decorated with class textlimited and have a maxlength
$('.textlimited[maxlength]').keyup(function(){
//get the fields limit
var maxLength = $(this).attr("maxlength");
// check if the limit is passed
if(this.value.length > maxLength){
return false;
}
// find the counter element by the id specified in the source input element
var counterElement = $(".textcounter#" + $(this).data("textcounterid"));
// update counter 's text
counterElement.html((maxLength - this.value.length) + " chars left");
});

Let's try to take an example and understand:
I have a branch, say master, pointing to X <commit-id>, and I have a new branch pointing to Y <sha1>.
Where Y <commit-id> = <master> branch commits - few commits
Now say for Y branch I have to gap-close the commits between the master branch and the new branch. Below is the procedure we can follow:
Step 1:
git checkout -b local origin/new
where local is the branch name. Any name can be given.
Step 2:
git merge origin/master --no-ff --stat -v --log=300
Merge the commits from master branch to new branch and also create a merge commit of log message with one-line descriptions from at most <n> actual commits that are being merged.
For more information and parameters about Git merge, please refer to:
git merge --help
Also if you need to merge a specific commit, then you can use:
git cherry-pick <commit-id>

Image Magick has been mentioned. There is a JNI front end project called JMagick. It's not a particularly stable project (and Image Magick itself has been known to change a lot and even break compatibility). That said, we've had good experience using JMagick and a compatible version of Image Magick in a production environment to perform scaling at a high throughput, low latency rate. Speed was substantially better then with an all Java graphics library that we previously tried.

Bash supports all sorts of wildcards and expansions.
Your exact case would be handled by brace expansion, like so:
$ rm -rf abc.log.2012-03-{14,27,28}
The above would expand to a single command with all three arguments, and be equivalent to typing:
$ rm -rf abc.log.2012-03-14 abc.log.2012-03-27 abc.log.2012-03-28
It's important to note that this expansion is done by the shell, before rm
is even loaded.
Can you provide an example of what did not work? As you likely know, the Wiring language is based on C/C++, however, not all of C++ is supported.
Whether you are allowed to create classes in the Wiring IDE, I'm not sure (my first Arduino is in the mail right now). I do know that if you wrote a C++ class, compiled it using AVR-GCC, then loaded it on your Arduino using AVRDUDE, it would work.
Your regex says the following:
/^ - if the line starts with
( - start a capture group
Clinton| - "Clinton"
| - or
[^Bush] - Any single character except "B", "u", "s" or "h"
| - or
Reagan) - "Reagan". End capture group.
/i - Make matches case-insensitive
So, in other words, your middle part of the regex is screwing you up. As it is a "catch-all" kind of group, it will allow any line that does not begin with any of the upper or lower case letters in "Bush". For example, these lines would match your regex:
Our president, George Bush
In the news today, pigs can fly
012-3123 33
You either make a negative look-ahead, as suggested earlier, or you simply make two regexes:
if( ($string =~ m/^(Clinton|Reagan)/i) and
($string !~ m/^Bush/i) ) {
print "$string\n";
}
As mirod has pointed out in the comments, the second check is quite unnecessary when using the caret (^
) to match only beginning of lines, as lines that begin with "Clinton" or "Reagan" could never begin with "Bush".
However, it would be valid without the carets.
I had this problem while inheriting from ApiController instead of the regular Controller class. I solved it by using var container = Request.GetQueryNameValuePairs().ToLookup(x => x.Key, x => x.Value);
I followed this thread How to get Request Querystring values?
EDIT: After trying to filter through the container I was getting odd error messages. After going to my project properties and I unchecked the Optimize Code checkbox which changed so that all of a sudden the parameters in my controller where filled up from the url as I wanted.
Hopefully this will help someone with the same problem..
Bootstrap 4.1+
Here are 5 equal, full-width columns (no extra CSS or SASS) using the auto-layout grid:
<div class="container-fluid">
<div class="row">
<div class="col">1</div>
<div class="col">2</div>
<div class="col">3</div>
<div class="col">4</div>
<div class="col">5</div>
</div>
</div>
http://codeply.com/go/MJTglTsq9h
This solution works because Bootstrap 4 is now flexbox. You can get the 5 columns to wrap within the same .row
using a break such as <div class="col-12"></div>
or <div class="w-100"></div>
every 5 columns.
Also see: Bootstrap - 5 column layout
Of course, there is nothing that says the extension of a header file must be .h

I am using Windows and get the same error message. I find another problem which is relevant. I defined OpenCV_DIR in my path at the end of the line. However when I typed "path" in the command line, my OpenCV_DIR was not shown. I found because Windows probably has a limit on how long the path can be, it cut my OpenCV_DIR to be only part of what I defined. So I removed some other part of the path, now it works.

You can check jQuery FAQ .
It turns out you're asking the wrong question. I also asked the wrong question. The reason it's wrong is the beginning of the first sentence: "In my bash script...".
I had the same question & made the same mistake. If you're using bash, you don't need to use sed to do string replacements (and it's much cleaner to use the replace feature built into bash).
Instead of something like, for example:
function escape-all-funny-characters() { UNKNOWN_CODE_THAT_ANSWERS_THE_QUESTION_YOU_ASKED; }
INPUT='some long string with KEYWORD that need replacing KEYWORD.'
A="$(escape-all-funny-characters 'KEYWORD')"
B="$(escape-all-funny-characters '<funny characters here>')"
OUTPUT="$(sed "s/$A/$B/g" <<<"$INPUT")"
you can use bash features exclusively:
INPUT='some long string with KEYWORD that need replacing KEYWORD.'
A='KEYWORD'
B='<funny characters here>'
OUTPUT="${INPUT//"$A"/"$B"}"

The file:
URL scheme refers to a file on the client machine. There is no hostname in the file:
scheme; you just provide the path of the file. So, the file on your local machine would be file:///~User/2ndFile.html
. Notice the three slashes; the hostname part of the URL is empty, so the slash at the beginning of the path immediately follows the double slash at the beginning of the URL. You will also need to expand the user's path; ~
does no expand in a file:
URL. So you would need file:///home/User/2ndFile.html
(on most Unixes), file:///Users/User/2ndFile.html
(on Mac OS X), or file:///C:/Users/User/2ndFile.html
(on Windows).
Many browsers, for security reasons, do not allow linking from a file that is loaded from a server to a local file. So, you may not be able to do this from a page loaded via HTTP; you may only be able to link to file:

By default android will set Holo to the Dark theme. There is no theme called Holo.Dark, there's only Holo.Light, that's why you are getting the resource not found error.
So just set it to:

If you want to change one specific onclick event with jQuery, you better use the functions .on() and .off() with a namespace (see documentation).
Use .on()
to create your event and .off()
to remove it. You can also create a global object like g_specific_events_set = {};
to avoid duplicates:
$('#alert').click(function()_x000D_
{_x000D_
alert('First alert!');_x000D_
});_x000D_

Well, why not just add them to your existing character class?
var pattern = /[a-zA-Z0-9&._-]/
If you need to check whether a string consists of nothing but those characters you have to anchor the expression as well:
var pattern = /^[a-zA-Z0-9&._-]+$/
The added ^
and $
match the beginning and end of the string respectively.
Testing for letters, numbers or underscore can be done with \w
which shortens your expression:
var pattern = /^[\w&.-]+$/
As mentioned in the comment from Nathan, if you're not using the results from .match()
(it returns an array with what has been matched), it's better to use RegExp.test()
which returns a simple boolean:
if (pattern.test(qry)) {
// qry is non-empty and only contains letters, numbers or special characters.
}
Update 2
In case I have misread the question, the below will check if all three separate conditions are met.
if (/[a-zA-Z]/.test(qry) && /[0-9]/.test(qry) && /[&._-]/.test(qry)) {
// qry contains at least one letter, one number and one special character
}
As others have pointed out setInterval and setTimeout will do the trick. I wanted to highlight a bit more advanced technique that I learned from this excellent video by Paul Irish: http://paulirish.com/2010/10-things-i-learned-from-the-jquery-source/
For periodic tasks that might end up taking longer than the repeat interval (like an HTTP request on a slow connection) it's best not to use setInterval()
. If the first request hasn't completed and you start another one, you could end up in a situation where you have multiple requests that consume shared resources and starve each other. You can avoid this problem by waiting to schedule the next request until the last one has completed:
// Use a named immediately-invoked function expression.
(function worker() {
$.get('ajax/test.html', function(data) {
// Now that we've completed the request schedule the next one.
$('.result').html(data);
setTimeout(worker, 5000);
});
})();
For simplicity I used the success callback for scheduling. The down side of this is one failed request will stop updates. To avoid this you could use the complete callback instead:
(function worker() {
$.ajax({
url: 'ajax/test.html',
success: function(data) {
$('.result').html(data);
},
complete: function() {
// Schedule the next request when the current one's complete
setTimeout(worker, 5000);
}
});
})();
Now in latest pandas you can directly use df.plot.scatter function
df = pd.DataFrame([[5.1, 3.5, 0], [4.9, 3.0, 0], [7.0, 3.2, 1],
[6.4, 3.2, 1], [5.9, 3.0, 2]],
columns=['length', 'width', 'species'])
ax1 = df.plot.scatter(x='length',
y='width',
c='DarkBlue')

There can be an even simpler representation assuming that one has to only test graph algorithms not use them(graph) else where. This can be as a map from vertices to their adjacency lists as shown below :-
#include<bits/stdc++.h>
using namespace std;
/* implement the graph as a map from the integer index as a key to the adjacency list
* of the graph implemented as a vector being the value of each individual key. The
* program will be given a matrix of numbers, the first element of each row will
* represent the head of the adjacency list and the rest of the elements will be the
* list of that element in the graph.
*/
typedef map<int, vector<int> > graphType;
int main(){
graphType graph;
int vertices = 0;
cout << "Please enter the number of vertices in the graph :- " << endl;
cin >> vertices;
if(vertices <= 0){
cout << "The number of vertices in the graph can't be less than or equal to 0." << endl;
exit(0);
}
cout << "Please enter the elements of the graph, as an adjacency list, one row after another. " << endl;
for(int i = 0; i <= vertices; i++){
vector<int> adjList; //the vector corresponding to the adjacency list of each vertex
int key = -1, listValue = -1;
string listString;
getline(cin, listString);
if(i != 0){
istringstream iss(listString);
iss >> key;
iss >> listValue;
if(listValue != -1){
adjList.push_back(listValue);
for(; iss >> listValue; ){
adjList.push_back(listValue);
}
graph.insert(graphType::value_type(key, adjList));
}
else
graph.insert(graphType::value_type(key, adjList));
}
}
//print the elements of the graph
cout << "The graph that you entered :- " << endl;
for(graphType::const_iterator iterator = graph.begin(); iterator != graph.end(); ++iterator){
cout << "Key : " << iterator->first << ", values : ";
vector<int>::const_iterator vectBegIter = iterator->second.begin();
vector<int>::const_iterator vectEndIter = iterator->second.end();
for(; vectBegIter != vectEndIter; ++vectBegIter){
cout << *(vectBegIter) << ", ";
}
cout << endl;
}
}
In Java SE environment, by specification you have to specify all classes as you have done:
A list of all named managed persistence classes must be specified in Java SE environments to insure portability
and
If it is not intended that the annotated persistence classes contained in the root of the persistence unit be included in the persistence unit, the exclude-unlisted-classes element should be used. The exclude-unlisted-classes element is not intended for use in Java SE environments.
(JSR-000220 6.2.1.6)
In Java EE environments, you do not have to do this as the provider scans for annotations for you.
Unofficially, you can try to set <exclude-unlisted-classes>false</exclude-unlisted-classes>
in your persistence.xml. This parameter defaults to false
in EE and true
in SE. Both EclipseLink and Toplink supports this as far I can tell. But you should not rely on it working in SE, according to spec, as stated above.
You can TRY the following (may or may not work in SE-environments):
<persistence-unit name="eventractor" transaction-type="RESOURCE_LOCAL">
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="hibernate.hbm2ddl.auto" value="validate" />
<property name="hibernate.show_sql" value="true" />

Look how I format my date $jour in the parameters. It depends if you use a expr()->like or a expr()->lte
$qb
->select('e')
->from('LdbPlanningBundle:EventEntity', 'e')
->where(
$qb->expr()->andX(
$qb->expr()->orX(
$qb->expr()->like('e.start', ':jour1'),
$qb->expr()->like('e.end', ':jour1'),
$qb->expr()->andX(
$qb->expr()->lte('e.start', ':jour2'),
$qb->expr()->gte('e.end', ':jour2')
)
),
$qb->expr()->eq('e.user', ':user')
)
)
->andWhere('e.user = :user ')
->setParameter('user', $user)
->setParameter('jour1', '%'.$jour->format('Y-m-d').'%')
->setParameter('jour2', $jour->format('Y-m-d'))
->getQuery()
->getArrayResult()

I think the source of confusion is the distinction between a node's attribute and the corresponding property.
You're using:
$("a.button").parents("form").attr("onsubmit")
You're directly reading the onsubmit
attribute's value (which must be a string). Instead, you should access the onsubmit
property of the node:
$("a.button").parents("form").prop("onsubmit")
Here's a quick test:
<form id="form1" action="foo1.htm" onsubmit="return valid()"></form>
<script>
window.onload = function () {
var form1 = document.getElementById("form1");
function log(s) {
document.write("<div>" + s + "</div>");
}
function info(v) {
return "(" + typeof v + ") " + v;
}
log("form1 onsubmit property: " + info(form1.onsubmit));
log("form1 onsubmit attribute: " + info(form1.getAttribute("onsubmit")));
};
</script>
This yields:
form1 onsubmit property: (function) function onsubmit(event) { return valid(); } form1 onsubmit attribute: (string) return valid()
One of the most easiest and shortest way is to add this code to your viewDidLoad
[self.view addGestureRecognizer:[[UITapGestureRecognizer alloc]
initWithTarget:self.view
action:@selector(endEditing:)]];
I would suggest using R and the package RSQLite
#install.packages("RSQLite") #perhaps needed
library("RSQLite")
# connect to the sqlite file
sqlite <- dbDriver("SQLite")
exampledb <- dbConnect(sqlite,"database.sqlite")
dbListTables(exampledb)
I am assuming you want to display this as part of the player.
This site breaks down how to get both the current and total time regardless of how you want to display it though using jQuery:
http://dev.opera.com/articles/view/custom-html5-video-player-with-css3-and-jquery/
This will also cover how to set it to a specific div. As philip has already mentioned, .currentTime will give you where you are in the video.
I hope this helps: How to trigger a Jenkins build on Git commit
It's just a matter of using curl to trigger a Jenkins job using the Git hooks provided by Git.
The command curl http://localhost:8080/job/someJob/build?delay=0sec
can run a Jenkins job, where someJob
is the name of the Jenkins job.
Search for the "hooks" folder in your hidden .git folder. Rename the "post-commit.sample" file to "post-commit". Open it with Notepad, remove the ": Nothing" line and paste the above command into it.
That's it. Whenever you do a commit, Git will trigger the post-commit commands defined in the file.
Adding mode:'no-cors'
to the request header guarantees that no response will be available in the response
Adding a "non standard" header, line 'access-control-allow-origin'
will trigger a OPTIONS preflight request, which your server must handle correctly in order for the POST request to even be sent
You're also doing fetch
wrong ... fetch
returns a "promise" for a Response
object which has promise creators for json
, text
, etc. depending on the content type...
In short, if your server side handles CORS correctly (which from your comment suggests it does) the following should work
function send(){
var myVar = {"id" : 1};
console.log("tuleb siia", document.getElementById('saada').value);
fetch("http://localhost:3000", {
method: "POST",
headers: {
"Content-Type": "text/plain"
},
body: JSON.stringify(myVar)
}).then(function(response) {
return response.json();
}).then(function(muutuja){
document.getElementById('väljund').innerHTML = JSON.stringify(muutuja);
});
}
however, since your code isn't really interested in JSON (it stringifies the object after all) - it's simpler to do
function send(){
var myVar = {"id" : 1};
console.log("tuleb siia", document.getElementById('saada').value);
fetch("http://localhost:3000", {
method: "POST",
headers: {
"Content-Type": "text/plain"
},
body: JSON.stringify(myVar)
}).then(function(response) {
return response.text();
}).then(function(muutuja){
document.getElementById('väljund').innerHTML = muutuja;
});
}
with BytesIO() as output:
from PIL import Image
with Image.open(filename) as img:
img.convert('RGB').save(output, 'BMP')
data = output.getvalue()[14:]
I just use this for add a image to clipboard in windows.
Try this,
1. If you want to skip a particular iteration, use continue.
2. If you want to break out of the immediate loop use break
3 If there are 2 loop, outer and inner.... and you want to break out of both the loop from
the inner loop, use break with label.
eg:
continue
for(int i=0 ; i<5 ; i++){
if (i==2){
continue;
}
}
eg:
break
for(int i=0 ; i<5 ; i++){
if (i==2){
break;
}
}
eg:
break with label
lab1: for(int j=0 ; j<5 ; j++){
for(int i=0 ; i<5 ; i++){
if (i==2){
break lab1;
}
}
}
This is due to the setting within IE Compatibility settings which says that all Intranet sites should run in compatibility mode. You can untick this via a group policy (or just plain unticking it in IE), or you can set the following:
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
Apparently it is not possible to change the compatibility view settings as a group policy but it is something that can perhaps be changed in the registry, this meta tag works fine for me, I had to make the required attribute work as part of a html form, it worked in chrome and firefox but not IE.
Here is a nice visual of what browsers support each individual html 5 element.
Notice the one common denominator Google Chrome, it supports everything. Hope this is of help
I wanted to do something similar, except setting the number to NaN rather than removing it from the data, since if you remove it you change the length which can mess up plotting (i.e. if you're only removing outliers from one column in a table, but you need it to remain the same as the other columns so you can plot them against each other).
To do so I used numpy's masking functions:
def reject_outliers(data, m=2):
stdev = np.std(data)
mean = np.mean(data)
maskMin = mean - stdev * m
maskMax = mean + stdev * m
mask = np.ma.masked_outside(data, maskMin, maskMax)
print('Masking values outside of {} and {}'.format(maskMin, maskMax))
return mask
By some reason sql server save some identity columns in different tables, the code that work for me, is the following:
select TABLE_NAME tabla,COLUMN_NAME columna
from INFORMATION_SCHEMA.COLUMNS
where COLUMNPROPERTY(object_id(TABLE_SCHEMA+'.'+TABLE_NAME), COLUMN_NAME, 'IsIdentity') = 1
union all
select o.name tabla, c.name columna
from sys.objects o
inner join sys.columns c on o.object_id = c.object_id
where c.is_identity = 1
The method of Srikar works very well, if you know both height and width of your new Size. If you for example know only the width you want to scale to and don't care about the height you first have to calculate the scale factor of the height.
+(UIImage*)imageWithImage: (UIImage*) sourceImage scaledToWidth: (float) i_width
{
float oldWidth = sourceImage.size.width;
float scaleFactor = i_width / oldWidth;
float newHeight = sourceImage.size.height * scaleFactor;
float newWidth = oldWidth * scaleFactor;
UIGraphicsBeginImageContext(CGSizeMake(newWidth, newHeight));
[sourceImage drawInRect:CGRectMake(0, 0, newWidth, newHeight)];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}
Because it makes these things so easy, you could consider using a JavaScript library like jQuery to do this:
<script>
$(document).ready(function() {
$('img.thumbnail').click(function() {
window.location.href = this.id + '.html';
});
});
</script>
Basically, it attaches an onClick
event to all images with class thumbnail
to redirect to the corresponding HTML page (id
+ .html
). Then you only need the images in your HTML (without the a
elements), like this:
<img src="bottle.jpg" alt="bottle" class="thumbnail" id="bottle" />
<img src="glass.jpg" alt="glass" class="thumbnail" id="glass" />
This will surely work:
UPDATE table1
SET table1.price=(SELECT table2.price
FROM table2
WHERE table2.id=table1.id AND table2.item=table1.item);
You can use the Feed Dialog via URL to emulate the behavior of Sharer.php, but it's a little more complicated. You need a Facebook App setup with the Base URL of the URL you plan to share configured. Then you can do the following:
1) Create a link like:
http://www.facebook.com/dialog/feed?app_id=[FACEBOOK_APP_ID]' +
'&link=[FULLY_QUALIFIED_LINK_TO_SHARE_CONTENT]' +
'&picture=[LINK_TO_IMAGE]' +
'&name=' + encodeURIComponent('[CONTENT_TITLE]') +
'&caption=' + encodeURIComponent('[CONTENT_CAPTION]) +
'&description=' + encodeURIComponent('[CONTENT_DESCRIPTION]') +
'&redirect_uri=' + FBVars.baseURL + '[URL_TO_REDIRECT_TO_AFTER_SHARE]' +
'&display=popup';
(obviously replace the [CONTENT] with the appropriate content. Documentation here: https://developers.facebook.com/docs/reference/dialogs/feed)
2) Open that link in a popup window with JavaScript on click of the share link
3) I like to create file (i.e. popupclose.html) to redirect users back to when they finish sharing, this file will contain <script>window.close();</script>
to close the popup window
The only downside of using the Feed Dialog (besides setup) is that, if you manage Pages as well, you don't have the ability to choose to share via a Page, only a regular user account can share. And it can give you some really cryptic error messages, most of them are related to the setup of your Facebook app or problems with either the content or URL you are sharing.
Like this... I used it to read Chinese characters...
Dim reader as StreamReader = My.Computer.FileSystem.OpenTextFileReader(filetoimport.Text)
Dim a as String
Do
a = reader.ReadLine
'
' Code here
'
Loop Until a Is Nothing
reader.Close()
The way I like to do this is using the %x
literal, which makes it easy (and readable!) to use quotes in a command, like so:
directorylist = %x[find . -name '*test.rb' | sort]
Which, in this case, will populate file list with all test files under the current directory, which you can process as expected:
directorylist.each do |filename|
filename.chomp!
# work with file
end
Memory Engine is not the solution you're looking for. You lose everything that you went to a database for in the first place (i.e. ACID).
Here are some better alternatives:
A LEFT [OUTER] JOIN can be faster than an equivalent subquery because the server might be able to optimize it better—a fact that is not specific to MySQL Server alone.
The last point is key. I used to love joins, but then had to run joins on a few tables with 100M+ rows. No good. Better off insert the data you're joining against into that target table (if it's not too much) and query against indexed columns and you'll get your query in a few ms.
I hope those help.

Let me throw out some example code that I got from http://www3.ntu.edu.sg/home/ehchua/programming/java/DateTimeCalendar.html Then you can play around with different options until you understand it.
import java.text.SimpleDateFormat;
import java.util.Date;
public class DateTest {
public static void main(String[] args) {
Date now = new Date();
//This is just Date's toString method and doesn't involve SimpleDateFormat
System.out.println("toString(): " + now); // dow mon dd hh:mm:ss zzz yyyy
//Shows "Mon Oct 08 08:17:06 EDT 2012"
SimpleDateFormat dateFormatter = new SimpleDateFormat("E, y-M-d 'at' h:m:s a z");
System.out.println("Format 1: " + dateFormatter.format(now));
// Shows "Mon, 2012-10-8 at 8:17:6 AM EDT"
dateFormatter = new SimpleDateFormat("E yyyy.MM.dd 'at' hh:mm:ss a zzz");
System.out.println("Format 2: " + dateFormatter.format(now));
// Shows "Mon 2012.10.08 at 08:17:06 AM EDT"
dateFormatter = new SimpleDateFormat("EEEE, MMMM d, yyyy");
System.out.println("Format 3: " + dateFormatter.format(now));
// Shows "Monday, October 8, 2012"
// SimpleDateFormat can be used to control the date/time display format:
// E (day of week): 3E or fewer (in text xxx), >3E (in full text)
// M (month): M (in number), MM (in number with leading zero)
// 3M: (in text xxx), >3M: (in full text full)
// h (hour): h, hh (with leading zero)
// m (minute)
// s (second)
// a (AM/PM)
// H (hour in 0 to 23)
// z (time zone)
// (there may be more listed under the API - I didn't check)
}
}
Good luck!

I tested as follows:
import numpy as np, datetime
# array of zeros and ones interleaved
lrg = np.arange(2).reshape((2,-1)).repeat(1000000,-1).flatten()
t0 = datetime.datetime.now()
flt = lrg[lrg==0]
print datetime.datetime.now() - t0
t0 = datetime.datetime.now()
flt = np.array(filter(lambda x:x==0, lrg))
print datetime.datetime.now() - t0
I got

Hi our sturucture is like Application, system, user_guide
create a folder name assets just near all the folders and then inside this assets folder create css and javascript and images folder put all your css js insiide the folders
now go to header.php and call the css just like this.
<link rel="stylesheet" href="<?php echo base_url();?>assets/css/touchTouch.css">
<link rel="stylesheet" href="<?php echo base_url();?>assets/css/style.css">
<link rel="stylesheet" href="<?php echo base_url();?>assets/css/camera.css">
You can use an ArrayList
and then use the toArray()
method. But depending on what you are doing, you might not even need an array at all. Look into seeing if Lists
are more what you want.

I followed the steps in killthrush's answer and to my surprise it did not work. Logging in as sa I could see my Windows domain user and had made them a sysadmin, but when I tried logging in with Windows auth I couldn't see my login under logins, couldn't create databases, etc. Then it hit me. That login was probably tied to another domain account with the same name (with some sort of internal/hidden ID that wasn't right). I had left this organization a while back and then came back months later. Instead of re-activating my old account (which they might have deleted) they created a new account with the same domain\username and a new internal ID. Using sa I deleted my old login, re-added it with the same name and added sysadmin. I logged back in with Windows Auth and everything looks as it should. I can now see my logins (and others) and can do whatever I need to do as a sysadmin using my Windows auth login.

I know I'm responding to an old post but I wanted to share an example of how to use Variable Tables when one wants to avoid using dynamic SQL. I'm not sure if its the most efficient way, however this has worked in the past for me when dynamic SQL was not an option.
Very simple just use this code, it will preserve the HTML, while removing unwrapped text only:
jQuery(function($){
// Replace 'td' with your html tag
$("td").html(function() {
// Replace 'ok' with string you want to change, you can delete 'hello everyone' to remove the text
return $(this).html().replace("ok", "hello everyone");
});
});
Here is full example: https://blog.hfarazm.com/remove-unwrapped-text-jquery/
You can do this with "just the regular expression" as you asked for in a comment:
(?<=sentence).*
(?<=sentence)
is a positive lookbehind assertion. This matches at a certain position in the string, namely at a position right after the text sentence
without making that text itself part of the match. Consequently, (?<=sentence).*
will match any text after sentence
.
This is quite a nice feature of regex. However, in Java this will only work for finite-length subexpressions, i. e. (?<=sentence|word|(foo){1,4})
is legal, but (?<=sentence\s*)
isn't.
You can use Thread.currentThread().getStackTrace()
.
That returns an array of StackTraceElement
s that represent the current stack trace of a program.
Just to add another option to Dónal's answer, you can also still use the good old java.lang.Object.getClass()
method.

You can prefix your cursor move commands with a number and that will repeat that command that many times
10Ctrl+E will do Ctrl+E 10 times instead of one.
As others have already said, type hinting currently only works for object types. But I think the particular error you've triggered might be in preparation of the upcoming string type SplString.
In theory it behaves like a string, but since it is an object would pass the object type verification. Unfortunately it's not yet in PHP 5.3, might come in 5.4, so haven't tested this.
delay
does not work on none queue functions, so we should use setTimeout()
.
And you don't need to separate things. All you need to do is including everything in a setTimeOut
method:
setTimeout(function () {
$("#div").addClass("error").delay(1000).removeClass("error");
}, 1000);
I had this problem in Intellij and it was because the ActionBarSherlock library I added to my project defined the android-support-v4.jar as a compile dependency and this jar was already included in my project so there were multiple copies/version of DEX at compile time.
The solution was to change the ActionBarSherlock module dependency for this jar to be Runtime instead of compile, as my project was already providing it.
You may be overcomplicating things, is there any reason you need the stringr package?
df <- data.frame(Date = c("10/9/2009 0:00:00", "10/15/2009 0:00:00"))
as.Date(df$Date, "%m/%d/%Y %H:%M:%S")
[1] "2009-10-09" "2009-10-15"
More generally and if you need the time component as well, use strptime:
strptime(df$Date, "%m/%d/%Y %H:%M:%S")
I'm guessing at what your actual data might look at from the partial results you give.
Just adding some extra sorting if needed
=QUERY(A2:A,"select A, count(A) where A is not null group by A order by count(A) DESC label A 'Name', count(A) 'Count'",-1)
Collector
:public static <T> Collector<T, ?, Optional<T>> toSingleton() {
return Collectors.collectingAndThen(
Collectors.toList(),
list -> list.size() == 1 ? Optional.of(list.get(0)) : Optional.empty()
);
}
Optional<User> result = users.stream()
.filter((user) -> user.getId() < 0)
.collect(toSingleton());
We return an Optional
, since we usually can't assume the Collection
to contain exactly one element. If you already know this is the case, call:
User user = result.orElseThrow();
This puts the burden of handeling the error on the caller - as it should.

A couple of scenarios might help illustrate the purpose of access and refresh tokens and the engineering trade-offs in designing an oauth2 (or any other auth) system:
In the web app scenario you have a couple of options:
Let's imagine that someone manages to hijack your session. The only thing that is possible is to request your pages.
Comparing 1 and 2:
In 1, access_token and refresh_token only travel over the wire on the way between the authorzation server (google in your case) and your app server. This would be done on a secure channel. A hacker could hijack the session but they would only be able to interact with your web app. In 2, the hacker could take the access_token away and form their own requests to the resources that the user has granted access to. Even if the hacker gets a hold of the access_token they will only have a short window in which they can access the resources.
Either way the refresh_token and clientid/secret are only known to the server making it impossible from the web browser to obtain long term access.
Let's imagine you are implementing oauth2 and set a long timeout on the access token:
In 1) There's not much difference here between a short and long access token since it's hidden in the app server. In 2) someone could get the access_token in the browser and then use it to directly access the user's resources for a long time.
On the mobile, there are a couple of scenarios that I know of:
Store clientid/secret on the device and have the device orchestrate obtaining access to the user's resources.
Use a backend app server to hold the clientid/secret and have it do the orchestration. Use the access_token as a kind of session key and pass it between the client and the app server.
Comparing 1 and 2
In 1) Once you have clientid/secret on the device they aren't secret any more. Anyone can decompile and then start acting as though they are you, with the permission of the user of course. The access_token and refresh_token are also in memory and could be accessed on a compromised device which means someone could act as your app without the user giving their credentials. In this scenario the length of the access_token makes no difference to the hackability since refresh_token is in the same place as access_token. In 2) the clientid/secret nor the refresh token are compromised. Here the length of the access_token expiry determines how long a hacker could access the users resources, should they get hold of it.
Here it depends upon what you're securing with your auth system as to how long your access_token expiry should be. If it's something particularly valuable to the user it should be short. Something less valuable, it can be longer.
Some people like google don't expire the refresh_token. Some like stackflow do. The decision on the expiry is a trade-off between user ease and security. The length of the refresh token is related to the user return length, i.e. set the refresh to how often the user returns to your app. If the refresh token doesn't expire the only way they are revoked is with an explicit revoke. Normally, a log on wouldn't revoke.
Hope that rather length post is useful.
On some Samsung devices the mode change that can be set by dialing *#0808#
doesn't stick without direct reboot. Once rebooted, dial the same string and make sure that you have adb + mdp
selected and USB set to AP
. After this make sure to reconnect phone and restart ADB server. Also try to avoid USB hubs and virtual machines witch surely complicate matter further. The follow the previously mentioned instructions for clearing authorized devices etc.
The Abstract Factory pattern is used in various places.
E.g., DatagramSocketImplFactory
, PreferencesFactory
. There are many more---search the Javadoc for interfaces which have the word "Factory" in their name.
Also there are quite a few instances of the Factory pattern, too.

int[]

are represented the same way, except int[] allocates (IIRC).
ap
is a pointer, therefore giving it the value of an integer is dangerous, as you have no idea what's at address 45.
when you try to access it (x = *ap
), you try to access address 45, which causes the crash, as it probably is not a part of the memory you can access.
Removing "Launch screen interface file base name" from Info.plist file AND trashing "Launch Screen.xib" worked for me.
You can try something like process.argv
, that is if you are using node.js
to run the program.
console.log(process.argv)
=> Would print an array containing
[
'/usr/bin/node',
'/home/user/path/filename.js',
'your_input'
]
You get the user provided input via array index, i.e., console.log(process.argv[3])
This should provide you with the input which you can store.
Example:
var somevariable = process.argv[3]; // input one
var somevariable2 = process.argv[4]; // input two
console.log(somevariable);
console.log(somevariable2);
If you are building a command-line program then the npm package yargs would be really helpful.
Just thought I'd add my two cents. The picker is being used on an add/update form, so it needed to show the date coming from the database if editing an existing record, or show today's date if not. Below is working fine for me:
$( "#datepicker" ).datepicker();
<?php if (!empty($oneEVENT['start_ts'])): ?>
$( "#datepicker" ).datepicker( "setDate", "<?php echo $startDATE; ?>" );
<? else: ?>
$("#datepicker").datepicker('setDate', new Date());
<?php endif; ?>
});
Functions that send/modify HTTP headers must be invoked before any output is made. summary ? Otherwise the call fails:
Warning: Cannot modify header information - headers already sent (output started at script:line)
Some functions modifying the HTTP header are:
Output can be:
Unintentional:
<?php
or after ?>
Intentional:
print
, echo
and other functions producing output<html>
sections prior <?php
code. To understand why headers must be sent before output it's necessary to look at a typical HTTP response. PHP scripts mainly generate HTML content, but also pass a set of HTTP/CGI headers to the webserver:
HTTP/1.1 200 OK
Powered-By: PHP/5.3.7
Vary: Accept-Encoding
Content-Type: text/html; charset=utf-8
<html><head><title>PHP page output page</title></head>
<body><h1>Content</h1> <p>Some more output follows...</p>
and <a href="/"> <img src=internal-icon-delayed> </a>
The page/output always follows the headers. PHP has to pass the headers to the webserver first. It can only do that once. After the double linebreak it can nevermore amend them.
When PHP receives the first output (print
, echo
, <html>
) it will
flush all collected headers. Afterwards it can send all the output
it wants. But sending further HTTP headers is impossible then.
The header()
warning contains all relevant information to
locate the problem cause:
Warning: Cannot modify header information - headers already sent by (output started at /www/usr2345/htdocs/auth.php:52) in /www/usr2345/htdocs/index.php on line 100
Here "line 100" refers to the script where the header()
invocation failed.
The "output started at" note within the parenthesis is more significant.
It denominates the source of previous output. In this example it's auth.php
and line 52
. That's where you had to look for premature output.
Typical causes:
Intentional output from print
and echo
statements will terminate
the opportunity to send HTTP headers. The application flow must
be restructured to avoid that. Use functions
and templating schemes. Ensure header()
calls occur before messages
are written out.
Functions that produce output include
print
, echo
, printf
, vprintf
trigger_error
, ob_flush
, ob_end_flush
, var_dump
, print_r
readfile
, passthru
, flush
, imagepng
, imagejpeg
among others and user-defined functions.
Unparsed HTML sections in a .php
file are direct output as well.
Script conditions that will trigger a header()
call must be noted
before any raw <html>
blocks.
<!DOCTYPE html>
<?php
// Too late for headers already.
Use a templating scheme to separate processing from output logic.
<?php
for "script.php line 1" warningsIf the warning refers to output in line 1
, then it's mostly
leading whitespace, text or HTML before the opening <?php
token.
<?php
# There's a SINGLE space/newline before <? - Which already seals it.
Similarly it can occur for appended scripts or script sections:
?>
<?php
PHP actually eats up a single linebreak after close tags. But it won't compensate multiple newlines or tabs or spaces shifted into such gaps.
Linebreaks and spaces alone can be a problem. But there are also "invisible"
character sequences which can cause this. Most famously the
UTF-8 BOM (Byte-Order-Mark)
which isn't displayed by most text editors. It's the byte sequence EF BB BF
, which
is optional and redundant for UTF-8 encoded documents. PHP however has to treat
it as raw output. It may show up as the characters 
in the output (if the client
interprets the document as Latin-1) or similar "garbage".
In particular graphical editors and Java based IDEs are oblivious to its presence. They don't visualize it (obliged by the Unicode standard). Most programmer and console editors however do:
There it's easy to recognize the problem early on. Other editors may identify
its presence in a file/settings menu (Notepad++ on Windows can identify and
remedy the problem),
Another option to inspect the BOMs presence is resorting to an hexeditor.
On *nix systems hexdump
is usually available,
if not a graphical variant which simplifies auditing these and other issues:
An easy fix is to set the text editor to save files as "UTF-8 (no BOM)" or similar such nomenclature. Often newcomers otherwise resort to creating new files and just copy&pasting the previous code back in.
There are also automated tools to examine and rewrite text files
(sed
/awk
or recode
).
For PHP specifically there's the phptags
tag tidier.
It rewrites close and open tags into long and short forms, but also easily
fixes leading and trailing whitespace, Unicode and UTF-x BOM issues:
phptags --whitespace *.php
It's sane to use on a whole include or project directory.
?>
If the error source is mentioned as behind the
closing ?>
then this is where some whitespace or raw text got written out.
The PHP end marker does not terminate script executation at this
point. Any text/space characters after it will be written out as page content
still.
It's commonly advised, in particular to newcomers, that trailing ?>
PHP
close tags should be omitted. This eschews a small portion of these cases.
(Quite commonly include()d
scripts are the culprit.)
It's typically a PHP extension or php.ini setting if no error source is concretized.
gzip
stream encoding setting
or the ob_gzhandler
.extension=
module
generating an implicit PHP startup/warning message.If another PHP statement or expression causes a warning message or notice being printeded out, that also counts as premature output.
In this case you need to eschew the error,
delay the statement execution, or suppress the message with e.g.
isset()
or @()
-
when either doesn't obstruct debugging later on.
If you have error_reporting
or display_errors
disabled per php.ini
,
then no warning will show up. But ignoring errors won't make the problem go
away. Headers still can't be sent after premature output.
So when header("Location: ...")
redirects silently fail it's very
advisable to probe for warnings. Reenable them with two simple commands
atop the invocation script:
error_reporting(E_ALL);
ini_set("display_errors", 1);
Or set_error_handler("var_dump");
if all else fails.
Speaking of redirect headers, you should often use an idiom like this for final code paths:
exit(header("Location: /finished.html"));
Preferrably even a utility function, which prints a user message
in case of header()
failures.
PHPs output buffering is a workaround to alleviate this issue. It often works reliably, but shouldn't substitute for proper application structuring and separating output from control logic. Its actual purpose is minimizing chunked transfers to the webserver.
The output_buffering=
setting nevertheless can help.
Configure it in the php.ini
or via .htaccess
or even .user.ini on
modern FPM/FastCGI setups.
Enabling it will allow PHP to buffer output instead of passing it to the webserver
instantly. PHP thus can aggregate HTTP headers.
It can likewise be engaged with a call to ob_start();
atop the invocation script. Which however is less reliable for multiple reasons:
Even if <?php ob_start(); ?>
starts the first script, whitespace or a
BOM might get shuffled before, rendering it ineffective.
It can conceal whitespace for HTML output. But as soon as the application
logic attempts to send binary content (a generated image for example),
the buffered extraneous output becomes a problem. (Necessitating ob_clean()
as furher workaround.)
The buffer is limited in size, and can easily overrun when left to defaults. And that's not a rare occurence either, difficult to track down when it happens.
Both approaches therefore may become unreliable - in particular when switching between development setups and/or production servers. Which is why output buffering is widely considered just a crutch / strictly a workaround.
See also the basic usage example in the manual, and for more pros and cons:
If you didn't get the headers warning before, then the output buffering php.ini setting has changed. It's likely unconfigured on the current/new server.
headers_sent()
You can always use headers_sent()
to probe if
it's still possible to... send headers. Which is useful to conditionally print
an info or apply other fallback logic.
if (headers_sent()) {
die("Redirect failed. Please click on this link: <a href=...>");
}
else{
exit(header("Location: /user.php"));
}
Useful fallback workarounds are:
<meta>
tagIf your application is structurally hard to fix, then an easy (but
somewhat unprofessional) way to allow redirects is injecting a HTML
<meta>
tag. A redirect can be achieved with:
<meta http-equiv="Location" content="http://example.com/">
Or with a short delay:
<meta http-equiv="Refresh" content="2; url=../target.html">
This leads to non-valid HTML when utilized past the <head>
section.
Most browsers still accept it.
As alternative a JavaScript redirect can be used for page redirects:
<script> location.replace("target.html"); </script>
While this is often more HTML compliant than the <meta>
workaround,
it incurs a reliance on JavaScript-capable clients.
Both approaches however make acceptable fallbacks when genuine HTTP header() calls fail. Ideally you'd always combine this with a user-friendly message and clickable link as last resort. (Which for instance is what the http_redirect() PECL extension does.)
setcookie()
and session_start()
are also affectedBoth setcookie()
and session_start()
need to send a Set-Cookie:
HTTP header.
The same conditions therefore apply, and similar error messages will be generated
for premature output situations.
(Of course they're furthermore affected by disabled cookies in the browser, or even proxy issues. The session functionality obviously also depends on free disk space and other php.ini settings, etc.)
You can try this:
const data = {
name : "Test",
value: 12
}
if("name" in data){
//Found
}
else {
//Not found
}
You appear to have a heredoc
containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc
:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF
or if BUILDING
is $2
in your script:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF
If your file.sql
had an exit
at the end then it would be even simpler as you wouldn't need the heredoc
:
sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2
In your SQL you can then refer to the position parameters using substitution variables:
...
}',SEM_Models('&1'),NULL,
...
The &1
will be replaced with the first value passed to the SQL script, BUILDING
; because that is a string it still needs to be enclosed in quotes. You might want to set verify off
to stop if showing you the substitutions in the output.
You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1
, the second is &2
, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF
or:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF
If total_count
is being passed to your shell script then just use its positional parameter, $4
or whatever. And your SQL would then be:
SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
?s rdf:type :ProcessSpec .
?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));
If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:
define MY_ALIAS = &1
define MY_MODEL = &2
SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
?s rdf:type :ProcessSpec .
?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));
From your separate question, maybe you just wanted:
SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
?s rdf:type :ProcessSpec .
?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));
... so the alias will be the same value you're querying on (the value in $2
, or BUILDING
in the original part of the answer). You can refer to a substitution variable as many times as you want.
That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:
select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT
If you set pages 0
and set heading off
, your repeated calls might appear in a neat list. You might also need to set tab off
and possibly use rpad('&1', 20)
or similar to make that column always the same width. Or get the results as CSV with:
select '&1' ||','|| COUNT(*)
Depends what you're using the results for...
One more solution:
#footer { display:table; margin:0 auto; }
#footer li { display:table-cell; padding: 0px 10px; }
Then ul doesn't jump to the next line in case of zooming text.
Perhaps you need a selected range in addition to cursor position. Here is a simple function, you don't even need jQuery:
function caretPosition(input) {
var start = input[0].selectionStart,
end = input[0].selectionEnd,
diff = end - start;
if (start >= 0 && start == end) {
// do cursor position actions, example:
console.log('Cursor Position: ' + start);
} else if (start >= 0) {
// do ranged select actions, example:
console.log('Cursor Position: ' + start + ' to ' + end + ' (' + diff + ' selected chars)');
}
}
Let's say you wanna call it on an input whenever it changes or mouse moves cursor position (in this case we are using jQuery .on()
). For performance reasons, it may be a good idea to add setTimeout()
or something like Underscores _debounce()
if events are pouring in:
$('input[type="text"]').on('keyup mouseup mouseleave', function() {
caretPosition($(this));
});
Here is a fiddle if you wanna try it out: https://jsfiddle.net/Dhaupin/91189tq7/

One can invoke mysqldump locally against a remote server.
Example that worked for me:
mysqldump -h hostname-of-the-server -u mysql_user -p database_name > file.sql
I followed the mysqldump documentation on connection options.
MSSQL requires that variables within procedures be DECLAREd and folks use the @Variable syntax (DECLARE @TEXT VARCHAR(25) = 'text'). Also, MS allows for declares within any block in the procedure, unlike mySQL which requires all the DECLAREs at the top.
While good on the command line, I feel using the "set = @variable" within stored procedures in mySQL is risky. There is no scope and variables live across scope boundaries. This is similar to variables in JavaScript being declared without the "var" prefix, which are then the global namespace and create unexpected collisions and overwrites.
I am hoping that the good folks at mySQL will allow DECLARE @Variable at various block levels within a stored procedure. Notice the @ (at sign). The @ sign prefix helps to separate variable names from table column names - as they are often the same. Of course, one can always add an "v" or "l_" prefix, but the @ sign is a handy and succinct way to have the variable name match the column you might be extracting the data from without clobbering it.
MySQL is new to stored procedures and they have done a good job for their first version. It will be a pleaure to see where they take it form here and to watch the server side aspects of the language mature.

It looks like ncp and wrench both are no longer maintained. Probably the best option is to use fs-extra
The Developer of Wrench directs users to use fs-extra
as he has deprecated his library
copySync & moveSync both will copy and move folders even if they have files or subfolders and you can easily move or copy files using it
const fse = require('fs-extra');
const srcDir = `path/to/file`;
const destDir = `path/to/destination/directory`;
// To copy a folder or file
fse.copySync(srcDir, destDir, function (err) {
if (err) { ^
console.error(err); |___{ overwrite: true } // add if you want to replace existing folder or file with same name
} else {
console.log("success!");
}
});
OR
// To copy a folder or file

You can set nativeQuery = true
in the @Query
annotation from a Repository
class like this:
public static final String FIND_PROJECTS = "SELECT projectId, projectName FROM projects";
@Query(value = FIND_PROJECTS, nativeQuery = true)
public List<Object[]> findProjects();
Note that you will have to do the mapping yourself though. It's probably easier to just use the regular mapped lookup like this unless you really only need those two values:
public List<Project> findAll()
It's probably worth looking at the Spring data docs as well.
Go to Messages Gradle Sync, and Click on Install Repository and sync project. This is will install needed file in Android SDK and after syncing you will be able to create gradle or run your project.
You might want to consider some automated tool to do the encryption / decryption code generation eg. https://www.stringencrypt.com/java-encryption/
It can generate different encryption and decryption code each time for the string or file encryption.
It's pretty handy when it comes to fast string encryption without using RSA, AES etc.
Sample results:
// encrypted with https://www.stringencrypt.com (v1.1.0) [Java]
// szTest = "Encryption in Java!"
String szTest = "\u9E3F\uA60F\uAE07\uB61B\uBE1F\uC62B\uCE2D\uD611" +
"\uDE03\uE5FF\uEEED\uF699\uFE3D\u071C\u0ED2\u1692" +
"\u1E06\u26AE\u2EDC";
for (int iatwS = 0, qUJQG = 0; iatwS < 19; iatwS++)
{
qUJQG = szTest.charAt(iatwS);
qUJQG ++;
qUJQG = ((qUJQG << 5) | ( (qUJQG & 0xFFFF) >> 11)) & 0xFFFF;
qUJQG -= iatwS;
qUJQG = (((qUJQG & 0xFFFF) >> 6) | (qUJQG << 10)) & 0xFFFF;
qUJQG ^= iatwS;
qUJQG -= iatwS;
qUJQG = (((qUJQG & 0xFFFF) >> 3) | (qUJQG << 13)) & 0xFFFF;
qUJQG ^= 0xFFFF;
qUJQG ^= 0xB6EC;
qUJQG = ((qUJQG << 8) | ( (qUJQG & 0xFFFF) >> 8)) & 0xFFFF;
qUJQG --;
qUJQG = (((qUJQG & 0xFFFF) >> 5) | (qUJQG << 11)) & 0xFFFF;
qUJQG ++;
qUJQG ^= 0xFFFF;
qUJQG += iatwS;
szTest = szTest.substring(0, iatwS) + (char)(qUJQG & 0xFFFF) + szTest.substring(iatwS + 1);
}

Its not a good idea to pass Context
objects around. This often will lead to memory leaks. My suggestion is that you don't do it. I have made numerous Android apps without having to pass context to non-activity classes in the app. A better idea would be to get the resources you need access to while your in the Activity
or Fragment
, and hold onto it in another class. You can then use that class in any other classes in your app to access the resources, without having to pass around Context
objects.
I have seen solutions for aligning drawable at start/left but nothing for drawable end/right, so I came up with this solution. It uses dynamically calculated paddings for aligning drawable and text on both left and right side.
class IconButton @JvmOverloads constructor(
context: Context,
attrs: AttributeSet? = null,
defStyle: Int = R.attr.buttonStyle
) : AppCompatButton(context, attrs, defStyle) {
init {

It is important to set gravity in your layout to either "center_vertical|start" or "center_vertical|end" depending on where do you set the icon. For example:
<com.stackoverflow.util.IconButton
android:id="@+id/cancel_btn"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:drawableStart="@drawable/cancel"
android:drawablePadding="@dimen/padding_small"
android:gravity="center_vertical|start"
android:text="Cancel" />
Only problem with this implementation is that button can only have single line of text, otherwise the area of the text fills the button and paddings will be 0.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/activity_register_header"
android:minHeight="50dp"
android:orientation="vertical"
android:visibility="gone" />
Try this piece of code..For me this code worked..
I experienced these errors when I was developing an npm package that had peerDependencies
. I had to ensure that any peerDependencies
were also listed as devDependencies
. The project would not automatically use the globally installed packages.
Since using the @Value("new Long("myconfig")") with cast could throw error on startup if the config is not found or if not in the same expected number format
We used the following approach and is working as expected with fail safe check.
@Configuration()
public class MyConfiguration {
Long DEFAULT_MAX_IDLE_TIMEOUT = 5l;
@Value("db.timeoutInString")
private String timeout;
public Long getTimout() {
final Long timoutVal = StringUtil.parseLong(timeout);
if (null == timoutVal) {
return DEFAULT_MAX_IDLE_TIMEOUT;
}
return timoutVal;
}
}
The commands below are for Mac but pretty similar to Linux (see the links below)
#Install pyenv
brew update
brew install pyenv
Let's say you have python 3.6 as your primary version on your mac:
python --version
Output:
Python <your current version>
pyenv install -l
Let's take 3.7.3:
pyenv install 3.7.3
Make sure to run this in the Terminal (add it to ~/.bashrc or ~/.zshrc):
export PATH="/Users/username/.pyenv:$PATH"
eval "$(pyenv init -)"
Now let's run it only on the opened terminal/shell:
pyenv shell 3.7.3
python --version
Output:
Python 3.7.3
And not less important unset it in the opened shell/iTerm:
pyenv shell --unset
The following statement appends the value to the element with the id of response
$('#response').append(total);
This makes it look like you are concatenating the strings, but you aren't, you're actually appending them to the element
change that to
$('#response').text(total);
You need to change the drop event so that it replaces the value of the element with the total, you also need to keep track of what the total is, I suggest something like the following
$(function() {
var data = [];
var total = 0;
$( "#draggable1" ).draggable();
$( "#draggable2" ).draggable();
$( "#draggable3" ).draggable();
$("#droppable_box").droppable({
drop: function(event, ui) {
var currentId = $(ui.draggable).attr('id');
data.push($(ui.draggable).attr('id'));
if(currentId == "draggable1"){
var myInt1 = parseFloat($('#MealplanCalsPerServing1').val());
}
if(currentId == "draggable2"){
var myInt2 = parseFloat($('#MealplanCalsPerServing2').val());
}
if(currentId == "draggable3"){
var myInt3 = parseFloat($('#MealplanCalsPerServing3').val());
}
if ( typeof myInt1 === 'undefined' || !myInt1 ) {
myInt1 = parseInt(0);
}
if ( typeof myInt2 === 'undefined' || !myInt2){
myInt2 = parseInt(0);
}
if ( typeof myInt3 === 'undefined' || !myInt3){
myInt3 = parseInt(0);
}
total += parseFloat(myInt1 + myInt2 + myInt3);
$('#response').text(total);
}
});
$('#myId').click(function(event) {
$.post("process.php", ({ id: data }), function(return_data, status) {
alert(data);
//alert(total);
});
});
});
I moved the var total = 0;
statement out of the drop event and changed the assignment statment from this
total = parseFloat(myInt1 + myInt2 + myInt3);
to this
total += parseFloat(myInt1 + myInt2 + myInt3);
Here is a working example http://jsfiddle.net/axrwkr/RCzGn/
You can use the following in htaccess to allow and deny access to your site :
SetEnvIf remote_addr ^1\.2\3\.4\.5$ allowedip=1
Order deny,allow
deny from all
allow from env=allowedip
We first set an env variable allowedip if the client ip address matches the pattern, if the pattern matches then env variable allowedip is assigned the value 1 .
In the next step, we use Allow,deny directives to allow and deny access to the site. Order deny,allow
represents the order of deny
and allow
. deny from all
this line tells the server to deny everyone. the last line allow from env=allowedip
allows access to a single ip address we set the env variable for.
Replace 1\.2\.3\.4\.5
with your allowed ip address.

UCanAccess is a pure Java JDBC driver that allows us to read from and write to Access databases without using ODBC. It uses two other packages, Jackcess and HSQLDB, to perform these tasks. The following is a brief overview of how to get it set up.
If your project uses Maven you can simply include UCanAccess via the following coordinates:
groupId: net.sf.ucanaccess
artifactId: ucanaccess
The following is an excerpt from pom.xml
, you may need to update the <version>
to get the most recent release:
<dependencies>
<dependency>
<groupId>net.sf.ucanaccess</groupId>
<artifactId>ucanaccess</artifactId>
<version>4.0.4</version>
</dependency>
</dependencies>
As mentioned above, UCanAccess requires Jackcess and HSQLDB. Jackcess in turn has its own dependencies. So to use UCanAccess you will need to include the following components:
UCanAccess (ucanaccess-x.x.x.jar)
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
Jackcess (jackcess-2.x.x.jar)
commons-lang (commons-lang-2.6.jar, or newer 2.x version)
commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)
Fortunately, UCanAccess includes all of the required JAR files in its distribution file. When you unzip it you will see something like
ucanaccess-4.0.1.jar
/lib/
commons-lang-2.6.jar
commons-logging-1.1.1.jar
hsqldb.jar
jackcess-2.1.6.jar
All you need to do is add all five (5) JARs to your project.
NOTE: Do not add
loader/ucanload.jar
to your build path if you are adding the other five (5) JAR files. TheUcanloadDriver
class is only used in special circumstances and requires a different setup. See the related answer here for details.
Eclipse: Right-click the project in Package Explorer and choose Build Path > Configure Build Path...
. Click the "Add External JARs..." button to add each of the five (5) JARs. When you are finished your Java Build Path should look something like this
NetBeans: Expand the tree view for your project, right-click the "Libraries" folder and choose "Add JAR/Folder...", then browse to the JAR file.
After adding all five (5) JAR files the "Libraries" folder should look something like this:
IntelliJ IDEA: Choose File > Project Structure...
from the main menu. In the "Libraries" pane click the "Add" (+
) button and add the five (5) JAR files. Once that is done the project should look something like this:
Now "U Can Access" data in .accdb and .mdb files using code like this
// assumes...
// import java.sql.*;
Connection conn=DriverManager.getConnection(
"jdbc:ucanaccess://C:/__tmp/test/zzz.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT [LastName] FROM [Clients]");
while (rs.next()) {
System.out.println(rs.getString(1));
}
At the time of writing this Q&A I had no involvement in or affiliation with the UCanAccess project; I just used it. I have since become a contributor to the project.
Since cP/WHM took away the ability to modify User privileges as root in PHPMyAdmin, you have to use the command line to:
mysql> GRANT FILE ON *.* TO 'user'@'localhost';
Step 2 is to allow that user to dump a file in a specific folder. There are a few ways to do this but I ended up putting a folder in :
/home/user/tmp/db
and
chown mysql:mysql /home/user/tmp/db
That allows the mysql user to write the file. As previous posters have said, you can use the MySQL temp folder too, I don't suppose it really matters but you definitely don't want to make it 0777 permission (world-writeable) unless you want the world to see your data. There is a potential problem if you want to rinse-repeat the process as INTO OUTFILE
won't work if the file exists. If your files are owned by a different user then just trying to unlink($file)
won't work. If you're like me (paranoid about 0777) then you can set your target directory using:
chmod($dir,0777)
just prior to doing the SQL command, then
chmod($dir,0755)
immediately after, followed by unlink(file)
to delete the file. This keeps it all running under your web user and no need to invoke the mysql user.
jupyter notebook --help-all
could be of help:
--notebook-dir=<Unicode> (NotebookManager.notebook_dir)
Default: u'/Users/me/ipynbs'
The directory to use for notebooks.
For example:
jupyter notebook --notebook-dir=/Users/yourname/folder1/folder2/
You can of course set it in your profiles if needed, you might need to escape backslash in Windows.
Note that this will override whatever path you might have set in a jupyter_notebook_config.py file. (Where you can set a variable c.NotebookApp.notebook_dir
that will be your default startup location.)
With the latest .NET Framework, it is possible to return a value from a separate thread using a Task, where the Result property blocks the calling thread until the task finishes:
Task<MyClass> task = Task<MyClass>.Factory.StartNew(() =>
{
string s = "my message";
double d = 3.14159;
return new MyClass { Name = s, Number = d };
});
MyClass test = task.Result;

fopen() is a C library function and so you won't see any syscall instructions in your code, just a regular function call. At some point, it does call open(2), but it does that via a trampoline. There is simply a jump to the VDSO page, which is provided by the kernel to every process. The VDSO then provides code to make the system call. On modern processors, the SYSCALL or SYSENTER instructions will be used, but you can also use INT 80h on x86 processors.

Here is a shorter, but complete code.
If you need a dialog with only one button:
await showDialog(
context: context,
builder: (context) => new AlertDialog(
title: new Text('Message'),
content: Text(
'Your file is saved.'),
actions: <Widget>[
new FlatButton(
onPressed: () {
Navigator.of(context, rootNavigator: true)
.pop(); // dismisses only the dialog and returns nothing
},
child: new Text('OK'),
),
],
),
);
If you need a dialog with Yes/No buttons:
onPressed: () async {
bool result = await showDialog(
context: context,
builder: (context) {
return AlertDialog(
title: Text('Confirmation'),
content: Text('Do you want to save?'),
actions: <Widget>[
new FlatButton(
onPressed: () {
Navigator.of(context, rootNavigator: true)
.pop(false); // dismisses only the dialog and returns false
},
child: Text('No'),
),
FlatButton(
onPressed: () {
Navigator.of(context, rootNavigator: true)
.pop(true); // dismisses only the dialog and returns true
},
child: Text('Yes'),
),
],
);
},
);
if (result) {
if (missingvalue) {
Scaffold.of(context).showSnackBar(new SnackBar(
content: new Text('Missing Value'),
));
} else {
saveObject();
Navigator.of(context).pop(_myObject); // dismisses the entire widget
}
} else {
Navigator.of(context).pop(_myObject); // dismisses the entire widget
}
}
select t2.*
from t1 join t2 on t2.url='site.com/path/%' + cast(t1.id as varchar) + '%/more'
where t1.id > 9000
Using concat like suggested is even better though
I've found that using this null comparison works well:
if (Combobox.SelectedItem != null){
//Do something
}
else{
MessageBox.show("Please select a item");
}
This will only accept the selected item and no other value which may have been entered manually by the user which could cause validation issues.
