For Java 8 Spring offers ifPresentOrElse
from "Utility methods to work with Optionals" to achieve what you want.
Example would be:
import static org.springframework.data.util.Optionals.ifPresentOrElse;
ifPresentOrElse(dao.find(), obj -> obj.setAvailable(true), () -> logger.fatal("Object not available"));
This error appear because the compiler could not found "my-upload-key.keystore" file in your project
After you have generated the file you need to paste it into project's andorid/app folder
this worked for me!
Use jackson-bom which will have all the three jackson versions.i.e.jackson-annotations, jackson-core and jackson-databind. This will resolve the dependencies related to those versions
<html><body><form><input type="password" placeholder="password" valid="123" readonly=" readonly"></input>
Simply call InetAddress.getByName(String host)
passing in your textual IP address.
From the javadoc: The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address.
This error may occurs in the case you use un-defined prefix such as:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TabHost
XYZ:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</TabHost>
Android compiler does not know what is XYZ since it was not defined yet.
In your case, you should add below define to root node of the xml file.
xmlns:android="http://schemas.android.com/apk/res/android"
This is of course not the best way to "splice" a string, I had given this as an example of how the implementation would be, which is flawed and very evident from a split(), splice() and join(). For a far better implementation, see Louis's method.
No, there is no such thing as a String.splice
, but you can try this:
newStr = str.split(''); // or newStr = [...str];
newStr.splice(2,5);
newStr = newStr.join('');
I realise there is no splice
function as in Arrays, so you have to convert the string into an array. Hard luck...
It allows you to provide a default value if the key is missing:
dictionary.get("bogus", default_value)
returns default_value
(whatever you choose it to be), whereas
dictionary["bogus"]
would raise a KeyError
.
If omitted, default_value
is None
, such that
dictionary.get("bogus") # <-- No default specified -- defaults to None
returns None
just like
dictionary.get("bogus", None)
would.
Even if its not inline-block
based, this solution might worth consideration (allows nearly same formatting control from upper levels).
ul {
display: table;
}
ul li {
display: table-cell;
}
</li><li>
)Don't use array_values
on your $row
$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
array_push($res_arr_values, $row);
}
Also, the preferred way to add a value to an array is writing $array[] = $value;
, not using array_push
$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
$res_arr_values[] = $row;
}
And a further optimization is not to call mysql_fetch_array($result, MYSQL_ASSOC)
but to use mysql_fetch_assoc($result)
directly.
$res_arr_values = array();
while ($row = mysql_fetch_assoc($result))
{
$res_arr_values[] = $row;
}
Yes and no.
Thread safety is a little bit more than just making sure your shared data is accessed by only one thread at a time. You have to ensure sequential access to shared data, while at the same time avoiding race conditions, deadlocks, livelocks, and resource starvation.
Unpredictable results when multiple threads are running is not a required condition of thread-safe code, but it is often a by-product. For example, you could have a producer-consumer scheme set up with a shared queue, one producer thread, and few consumer threads, and the data flow might be perfectly predictable. If you start to introduce more consumers you'll see more random looking results.
I got both errors: mostly reading initial communication packet
and reading authorization packet
one time. It seems random, but sometimes I was able to establish a connection after reboots, but after some time the error creeped back.
Avoiding the 5GHz WiFi in the client seems to have fixed the issue. That's what worked for me (server was always connected to 2.4GHz).
I tried everything from server versions, odbc connector versions, firewall settings, installing some windows update (and then uninstalling them), some of the answers posted here, etc... lost my entire sleep time for today. Super tired day awaits me.
There are two ways to delete an application you have uploaded from the Google Play Developer Console based off of the application's status within the Console. An app's status can be viewed from the "All Applications" tab listed in the furthest column. (See below)
Select your app from the list and at the top of the page, underneath your application name, it will say DRAFT in blue with the super low-profile option to delete it just to the right. Observe below:
Click that and you're done! Keep in mind: all of the work you have put into this application so far will be deleted from the Google Play Developer Console.
This method is similar, however it should be noted that it is not possible to permanently delete an app from your Developer Console once it has been published to the Play Store.
1) Select the application you would like to publish from the "All Applications" tab on the right of the screen
2) Below the title of the app, similar to how it was with the DRAFT application, there will be super low-profile text allowing you the option to unpublish your app from the Play Store. This process "may take a few hours to complete" as it is said by the Developer Console.
(Pictures on the way. As you have seen, my example app is still pending publication, lol)
I hope this helps to answer some people's questions.
See tables from Python string formatting to select the proper format layout. In your case it's %.2E
.
If you have a query with a lot of criteria, it can be tricky to remember what each one does. I add a text field into the original table - call it "comments" or "documentation". Then I include it in the query with a comment for each criteria.
Comments need to be written like like this so that all relevant rows are returned. Unfortunately, as I'm a new poster, I can't add a screenshot!
So here goes without
Field: | Comment |ContractStatus | ProblemDealtWith | ...... |
Table: | ElecContracts |ElecContracts | ElecContracts | ...... |
Sort:
Show:
Criteria | <> "all problems are | "objection" Or |
| picked up with this | "rejected" Or |
| criteria" OR Is Null | "rolled" |
| OR ""
<>
tells the query to choose rows that are not equal to the text you entered, otherwise it will only pick up fields that have text equal to your comment i.e. none!
" " enclose your comment in quotes
OR Is Null OR "" tells your query to include any rows that have no data in the comments field , otherwise it won't return anything!
FAT32
along with FAT16
and FAT12
are File System Types, but vfat
along with umsdos
and msdos
are drivers, used to mount the FAT file systems in Linux. The choosing of the driver determines how some of the features are applied to the file system, for example, systems mounted with msdos
driver don't have long filenames (they are 8.3 format). vfat
is the most common driver for mounting FAT32 file systems nowadays.
Source: this wikipedia article
Output of commands like df
and lsblk
indeed show vfat
as the File System Type. But sudo file -sL /dev/<partition>
shows FAT (32 bit)
if a File System is FAT32.
You can confirm vfat
is a module and not a File System Type by running modinfo vfat
.

Another way to totally override the cart.php is to copy:
woocommerce/templates/cart/cart.php to
yourtheme/woocommerce/cart/cart.php
Then do whatever you need at the yourtheme/woocommerce/cart/cart.php
This was clearer to me,
// declare calendar outside the scope of isWithinRange() so that we initialize it only once
private Calendar calendar = Calendar.getInstance();
public boolean isWithinRange(Date date, Date startDate, Date endDate) {
calendar.setTime(startDate);
int startDayOfYear = calendar.get(Calendar.DAY_OF_YEAR); // first day is 1, last day is 365
int startYear = calendar.get(Calendar.YEAR);
calendar.setTime(endDate);
int endDayOfYear = calendar.get(Calendar.DAY_OF_YEAR);
int endYear = calendar.get(Calendar.YEAR);
calendar.setTime(date);
int dayOfYear = calendar.get(Calendar.DAY_OF_YEAR);
int year = calendar.get(Calendar.YEAR);
return (year > startYear && year < endYear) // year is within the range
|| (year == startYear && dayOfYear >= startDayOfYear) // year is same as start year, check day as well
|| (year == endYear && dayOfYear < endDayOfYear); // year is same as end year, check day as well
}
You're resetting the margin on all elements in the second css block. Default margin is 40px - this should solve the problem:
.my_container ul {list-style:disc outside none; margin-left:40px;}
This gets the first of any visible common input, including textareas and select boxes. This also makes sure they aren't hidden, disabled or readonly. it also allows for a target div, which I use in my software (ie, first input inside of this form).
$("input:visible:enabled:not([readonly]),textarea:visible:enabled:not([readonly]),select:visible:enabled:not([readonly])",
target).first().focus();
Not sure if I understand your question, but max(id) won't give you the number of lines at all. For example if you have only one line with id = 13 (let's say you deleted the previous lines), you'll have max(id) = 13 but the number of rows is 1. The correct (and fastest) solution is to use count(). BTW if you wonder why there's a star, it's because you can count lines based on a criteria.
A while
loop can be simulated in cmd.exe
with:
:still_more_files
if %countfiles% leq 21 (
rem change countfile here
goto :still_more_files
)
For example, the following script:
@echo off
setlocal enableextensions enabledelayedexpansion
set /a "x = 0"
:more_to_process
if %x% leq 5 (
echo %x%
set /a "x = x + 1"
goto :more_to_process
)
endlocal
outputs:
0
1
2
3
4
5
For your particular case, I would start with the following. Your initial description was a little confusing. I'm assuming you want to delete files in that directory until there's 20 or less:
@echo off
set backupdir=c:\test
:more_files_to_process
for /f %%x in ('dir %backupdir% /b ^| find /v /c "::"') do set num=%%x
if %num% gtr 20 (
cscript /nologo c:\deletefile.vbs %backupdir%
goto :more_files_to_process
)
Using Javascript you can download like this in a simple method
var oReq = new XMLHttpRequest();
// The Endpoint of your server
var URLToPDF = "https://mozilla.github.io/pdf.js/web/compressed.tracemonkey-pldi-09.pdf";
// Configure XMLHttpRequest
oReq.open("GET", URLToPDF, true);
// Important to use the blob response type
oReq.responseType = "blob";
// When the file request finishes
// Is up to you, the configuration for error events etc.
oReq.onload = function() {
// Once the file is downloaded, open a new window with the PDF
// Remember to allow the POP-UPS in your browser
var file = new Blob([oReq.response], {
type: 'application/pdf'
});
// Generate file download directly in the browser !
saveAs(file, "mypdffilename.pdf");
};
oReq.send();
You can use this
whereDate('date', '=', $date)
If you give whereDate then compare only date from datetime field.
I'm writing an updated answer for Python 3 to this question.
How is
__eq__
handled in Python and in what order?a == b
It is generally understood, but not always the case, that a == b
invokes a.__eq__(b)
, or type(a).__eq__(a, b)
.
Explicitly, the order of evaluation is:
b
's type is a strict subclass (not the same type) of a
's type and has an __eq__
, call it and return the value if the comparison is implemented,a
has __eq__
, call it and return it if the comparison is implemented,__eq__
and it has it, then call and return it if the comparison is implemented,is
.We know if a comparison isn't implemented if the method returns NotImplemented
.
(In Python 2, there was a __cmp__
method that was looked for, but it was deprecated and removed in Python 3.)
Let's test the first check's behavior for ourselves by letting B subclass A, which shows that the accepted answer is wrong on this count:
class A:
value = 3
def __eq__(self, other):
print('A __eq__ called')
return self.value == other.value
class B(A):
value = 4
def __eq__(self, other):
print('B __eq__ called')
return self.value == other.value
a, b = A(), B()
a == b
which only prints B __eq__ called
before returning False
.
The other answers here seem incomplete and out of date, so I'm going to update the information and show you how how you could look this up for yourself.
This is handled at the C level.
We need to look at two different bits of code here - the default __eq__
for objects of class object
, and the code that looks up and calls the __eq__
method regardless of whether it uses the default __eq__
or a custom one.
__eq__
Looking __eq__
up in the relevant C api docs shows us that __eq__
is handled by tp_richcompare
- which in the "object"
type definition in cpython/Objects/typeobject.c
is defined in object_richcompare
for case Py_EQ:
.
case Py_EQ:
/* Return NotImplemented instead of False, so if two
objects are compared, both get a chance at the
comparison. See issue #1393. */
res = (self == other) ? Py_True : Py_NotImplemented;
Py_INCREF(res);
break;
So here, if self == other
we return True
, else we return the NotImplemented
object. This is the default behavior for any subclass of object that does not implement its own __eq__
method.
__eq__
gets calledThen we find the C API docs, the PyObject_RichCompare function, which calls do_richcompare
.
Then we see that the tp_richcompare
function, created for the "object"
C definition is called by do_richcompare
, so let's look at that a little more closely.
The first check in this function is for the conditions the objects being compared:
__eq__
method,then call the other's method with the arguments swapped, returning the value if implemented. If that method isn't implemented, we continue...
if (!Py_IS_TYPE(v, Py_TYPE(w)) &&
PyType_IsSubtype(Py_TYPE(w), Py_TYPE(v)) &&
(f = Py_TYPE(w)->tp_richcompare) != NULL) {
checked_reverse_op = 1;
res = (*f)(w, v, _Py_SwappedOp[op]);
if (res != Py_NotImplemented)
return res;
Py_DECREF(res);
Next we see if we can lookup the __eq__
method from the first type and call it.
As long as the result is not NotImplemented, that is, it is implemented, we return it.
if ((f = Py_TYPE(v)->tp_richcompare) != NULL) {
res = (*f)(v, w, op);
if (res != Py_NotImplemented)
return res;
Py_DECREF(res);
Else if we didn't try the other type's method and it's there, we then try it, and if the comparison is implemented, we return it.
if (!checked_reverse_op && (f = Py_TYPE(w)->tp_richcompare) != NULL) {
res = (*f)(w, v, _Py_SwappedOp[op]);
if (res != Py_NotImplemented)
return res;
Py_DECREF(res);
}
Finally, we get a fallback in case it isn't implemented for either one's type.
The fallback checks for the identity of the object, that is, whether it is the same object at the same place in memory - this is the same check as for self is other
:
/* If neither object implements it, provide a sensible default
for == and !=, but raise an exception for ordering. */
switch (op) {
case Py_EQ:
res = (v == w) ? Py_True : Py_False;
break;
In a comparison, we respect the subclass implementation of comparison first.
Then we attempt the comparison with the first object's implementation, then with the second's if it wasn't called.
Finally we use a test for identity for comparison for equality.
Here is the code little modified that i got it from google -
List data_table = new ArrayList<>();
Class.forName("oracle.jdbc.driver.OracleDriver");
con = DriverManager.getConnection(conn_url, user_id, password);
Statement stmt = con.createStatement();
System.out.println("query_string: "+query_string);
ResultSet rs = stmt.executeQuery(query_string);
ResultSetMetaData rsmd = rs.getMetaData();
int row_count = 0;
while (rs.next()) {
HashMap<String, String> data_map = new HashMap<>();
if (row_count == 240001) {
break;
}
for (int i = 1; i <= rsmd.getColumnCount(); i++) {
data_map.put(rsmd.getColumnName(i), rs.getString(i));
}
data_table.add(data_map);
row_count = row_count + 1;
}
rs.close();
stmt.close();
con.close();
If you are like me using a TFT that is connected via SPI (e. g. PiTFT 2.8" 320x240) driven by FBTFT in combination with fbcp to utilise hardware accelerated video decoding (using omxplayer) like it is descriped here. You should add the following into the /boot/config.txt
to force the output to HDMI and set the resolution to 320x240:
hdmi_force_hotplug=1
hdmi_cvt=320 240 60 1 0 0 0
hdmi_group=2
hdmi_mode=87
All arrays passed to php must be object literals. Here's an example from JS/jQuery:
var myarray = {}; //must be declared as an object literal first
myarray[fld1] = val; // then you can add elements and values
myarray[fld2] = val;
myarray[fld3] = Array(); // array assigned to an element must also be declared as object literal
etc...`
It can now be sent via Ajax in the data: parameter as follows:
data: { new_name: myarray },
php picks this up and reads it as a normal array without any decoding necessary. Here's an example:
$array = $_POST['new_name']; // myarray became new_name (see above)
$fld1 = array['fld1'];
$fld2 = array['fld2'];
etc...
However, when you return an array to jQuery via Ajax it must first be encoded using json. Here's an example in php:
$return_array = json_encode($return_aray));
print_r($return_array);
And the output from that looks something like this:
{"fname":"James","lname":"Feducia","vip":"true","owner":"false","cell_phone":"(801) 666-0909","email":"[email protected]", "contact_pk":"","travel_agent":""}
{again we see the object literal encoding tags} now this can be read by JS/jQuery as an array without any further action inside JS/JQuery... Here's an example in jquery ajax:
success: function(result) {
console.log(result);
alert( "Return Values: " + result['fname'] + " " + result['lname'] );
}
Error: 10060 Adding a timeout parameter to request solved the issue for me.
import urllib
import urllib2
g = "http://www.google.com/"
read = urllib2.urlopen(g, timeout=20)
A similar error also occurred while I was making a GET request. Again, passing a timeout
parameter solved the 10060 Error.
response = requests.get(param_url, timeout=20)
The most upvoted answer above is weird in a way that it simply clears the Clipboard and then gets the content (which is then empty). One could clear the clipboard to be sure that some clipboard content type like "formated text" does not "cover" your plain text content you want to save in the clipboard.
The following piece of code replaces all newlines in the clipboard by spaces, then removes all double spaces and finally saves the content back to the clipboard:
import win32clipboard
win32clipboard.OpenClipboard()
c = win32clipboard.GetClipboardData()
win32clipboard.EmptyClipboard()
c = c.replace('\n', ' ')
c = c.replace('\r', ' ')
while c.find(' ') != -1:
c = c.replace(' ', ' ')
win32clipboard.SetClipboardText(c)
win32clipboard.CloseClipboard()
You are setting the datasource inside of the loop and sleeping 500 after each add. Why not just add to itemstates and then set your datasource AFTER you have added everything. If you want the thread sleep after that fine. The first block of code here is yours the second block I modified.
for (int i = 0; i < 10; i++) {
itemStates.Add(new ItemState { Id = i.ToString() });
dataGridView1.DataSource = null;
dataGridView1.DataSource = itemStates;
System.Threading.Thread.Sleep(500);
}
Change your Code As follows: this is much faster.
for (int i = 0; i < 10; i++) {
itemStates.Add(new ItemState { Id = i.ToString() });
}
dataGridView1.DataSource = typeof(List);
dataGridView1.DataSource = itemStates;
System.Threading.Thread.Sleep(500);
It's impossible to say without seeing your actual code. Likely the reason is a code path through your function that doesn't execute a return
statement. When the code goes down that path, the function ends with no value returned, and so returns None
.
Updated: It sounds like your code looks like this:
def b(self, p, data):
current = p
if current.data == data:
return True
elif current.data == 1:
return False
else:
self.b(current.next, data)
That else clause is your None
path. You need to return the value that the recursive call returns:
else:
return self.b(current.next, data)
BTW: using recursion for iterative programs like this is not a good idea in Python. Use iteration instead. Also, you have no clear termination condition.
You can see your current session settings by querying nls_session_parameters
:
select value
from nls_session_parameters
where parameter = 'NLS_NUMERIC_CHARACTERS';
VALUE
----------------------------------------
.,
That may differ from the database defaults, which you can see in nls_database_parameters
.
In this session your query errors:
select to_number('100,12') from dual;
Error report -
SQL Error: ORA-01722: invalid number
01722. 00000 - "invalid number"
I could alter my session, either directly with alter session
or by ensuring my client is configured in a way that leads to the setting the string needs (it may be inherited from a operating system or Java locale, for example):
alter session set NLS_NUMERIC_CHARACTERS = ',.';
select to_number('100,12') from dual;
TO_NUMBER('100,12')
-------------------
100,12
In SQL Developer you can set your preferred value in Tool->Preferences->Database->NLS.
But I can also override that session setting as part of the query, with the optional third nlsparam parameter to to_number()
; though that makes the optional second fmt parameter necessary as well, so you'd need to be able pick a suitable format:
alter session set NLS_NUMERIC_CHARACTERS = '.,';
select to_number('100,12', '99999D99', 'NLS_NUMERIC_CHARACTERS='',.''')
from dual;
TO_NUMBER('100,12','99999D99','NLS_NUMERIC_CHARACTERS='',.''')
--------------------------------------------------------------
100.12
By default the result is still displayed with my session settings, so the decimal separator is still a period.
Many popular Java webapps, including Jenkins and Nexus, use this mechanism:
Optionally, check a servlet context-param / init-param. This allows configuring multiple webapp instances per servlet container, using context.xml
which can be done by modifying the WAR or by changing server settings (in case of Tomcat).
Check an environment variable (using System.getenv), if it is set, then use that folder as your application data folder. e.g. Jenkins uses JENKINS_HOME
and Nexus uses PLEXUS_NEXUS_WORK
. This allows flexible configuration without any changes to WAR.
Otherwise, use a subfolder inside user's home folder, e.g. $HOME/.yourapp
. In Java code this will be:
final File appFolder = new File(System.getProperty("user.home"), ".yourapp");
For negative integer value, SIGNED
is used and for non-negative integer value, UNSIGNED
is used. It always suggested to use UNSIGNED
for id as a PRIMARY KEY.
When doing a clean HTML Structure, you can use this.
//Jquery Code_x000D_
$('a#link_1').click(function(e){_x000D_
e . preventDefault () ;_x000D_
var a = e . target ;_x000D_
window . open ( '_top' , a . getAttribute ('href') ) ;_x000D_
});_x000D_
_x000D_
//Normal Code_x000D_
element = document . getElementById ( 'link_1' ) ;_x000D_
element . onClick = function (e) {_x000D_
e . preventDefault () ;_x000D_
_x000D_
window . open ( '_top' , element . getAttribute ('href') ) ;_x000D_
} ;
_x000D_
<a href="#Foo" id="link_1">Do it!</a>
_x000D_
In your invocation, the two functions are the same.
average
can compute a weighted average though.
Try using matplotlib.pyplot.ticklabel_format
:
import matplotlib.pyplot as plt
...
plt.ticklabel_format(style='sci', axis='x', scilimits=(0,0))
This applies scientific notation (i.e. a x 10^b
) to your x-axis tickmarks
You're right, no API at all that I'm aware to export PrivateKey marked as non-exportable. But if you patch (in memory) normal APIs, you can use the normal way to export :)
There is a new version of mimikatz that also support CNG Export (Windows Vista / 7 / 2008 ...)

If you need to do something on the front end you can respond to the onsubmit event of your form. If you are just posting to admin/start you can access post variables in your view through the request object. request.POST which is a dictionary of post variables

That is the textarea
's job - for multiline text input. The input
won't do it; it wasn't designed to do it.
So use a textarea
. Besides their visual differences, they are accessed via JavaScript the same way (use value
property).
You can prevent newlines being entered via the input
event and simply using a replace(/\n/g, '')
.
You can define the variable in General Declarations and then initialise it in the first event that fires in your environment.
Alternatively, you could create yourself a class with the relevant properties and initialise them in the Initialise method
Replace a Fragment using following code:
Fragment fragment = new AddPaymentFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.frame, fragment, "Tag_AddPayment")

@Override
public void onBackPressed() {
android.support.v4.app.FragmentManager fm = getSupportFragmentManager();
if (fm.getBackStackEntryCount() > 1) {
fm.popBackStack();
} else {
finish();
}

Try just clearing the data (not the entire table including headers):

Bit is only advantageous over the various byte options (tinyint, enum, char(1)) if you have a lot of boolean fields. One bit field still takes up a full byte. Two bit fields fit into that same byte. Three, four,five, six, seven, eight. After which they start filling up the next byte. Ultimately the savings are so small, there are thousands of other optimizations you should focus on. Unless you're dealing with an enormous amount of data, those few bytes aren't going to add up to much. If you're using bit with PHP you need to typecast the values going in and out.
If you install using bundler as suggested by gryzzly and the gem creates a binary then make sure you run it with bundle exec mygembinary
as the gem is stored in a bundler directory which is not visible on the normal gem path.
I find that Patrick Steele answered this question best on his blog: Avoiding IsNothing()
I did not copy any of his answer here, to ensure Patrick Steele get's credit for his post. But I do think if you're trying to decide whether to use Is Nothing or IsNothing you should read his post. I think you'll agree that Is Nothing is the best choice.
Edit - VoteCoffe's comment here
Partial article contents: After reviewing more code I found out another reason you should avoid this: It accepts value types! Obviously, since IsNothing() is a function that accepts an 'object', you can pass anything you want to it. If it's a value type, .NET will box it up into an object and pass it to IsNothing -- which will always return false on a boxed value! The VB.NET compiler will check the "Is Nothing" style syntax and won't compile if you attempt to do an "Is Nothing" on a value type. But the IsNothing() function compiles without complaints. -PSteele – VoteCoffee

alert("Data: " + data + "\nStatus: " + status);
$("#currSpecID").val(data);
});
In Mgmt Studio, when you are editing the top 200, you can view the SQL pane - either by right clicking in the grid and choosing Pane->SQL or by the button in the upper left. This will allow you to write a custom query to drill down to the row(s) you want to edit.
But ultimately mgmt studio isn't a data entry/update tool which is why this is a little cumbersome.
If you want to disable particular date(s) in jquery datepicker then here is the simple demo for you.
<script type="text/javascript">
var arrDisabledDates = {};
arrDisabledDates[new Date("08/28/2017")] = new Date("08/28/2017");
arrDisabledDates[new Date("12/23/2017")] = new Date("12/23/2017");
$(".datepicker").datepicker({
dateFormat: "dd/mm/yy",
beforeShowDay: function (date) {
var day = date.getDay(),
bDisable = arrDisabledDates[date];
if (bDisable)
return [false, "", ""]
}
});

I had the same error when I imported web requests from fiddler captured sessions to Visual Studio webtests. Some POST requests did not have a StringHttpBody tag. I added an empty one to them and the error was gone. Add this after the Headers tag:

The w3 org said:
By default, SGML requires that all attribute values be delimited using either double quotation marks (ASCII decimal 34) or single quotation marks (ASCII decimal 39). Single quote marks can be included within the attribute value when the value is delimited by double quote marks, and vice versa. Authors may also use numeric character references to represent double quotes (
"
) and single quotes ('
). For double quotes authors can also use the character entity reference"
.
So... seems to be no difference. Only depends on your style.
The replace function should work for you.
REPLACE(str,from_str,to_str)
Returns the string str with all occurrences of the string from_str replaced by the string to_str. REPLACE()
performs a case-sensitive match when searching for from_str.
just use this at the end of your button click event
protected void btnAddButton_Click(object sender, EventArgs e)

.Please use the following syntax to enjoy the luxury of asp.net tilda ("~") in javascript
<script src=<%=Page.ResolveUrl("~/MasterPages/assets/js/jquery.js")%>></script>
...but what about the previous round parenteses surrounding all the function declaration?
Specifically, it makes JavaScript interpret the 'function() {...}' construct as an inline anonymous function expression. If you omitted the brackets:
function() {
alert('hello');
}();
You'd get a syntax error, because the JS parser would see the 'function' keyword and assume you're starting a function statement of the form:
function doSomething() {
}
...and you can't have a function statement without a function name.
function expressions and function statements are two different constructs which are handled in very different ways. Unfortunately the syntax is almost identical, so it's not just confusing to the programmer, even the parser has difficulty telling which you mean!
You can set your test properties in src/test/resources/config/application.yml
file. Spring Boot test cases will take properties from application.yml
file in test directory.
The config
folder is predefined in Spring Boot.
As per documentation:
If you do not like application.properties as the configuration file name, you can switch to another file name by specifying a spring.config.name environment property. You can also refer to an explicit location by using the spring.config.location environment property (which is a comma-separated list of directory locations or file paths). The following example shows how to specify a different file name:
java -jar myproject.jar --spring.config.location=classpath:/default.properties,classpath:/override.properties
The same works for application.yml
Documentation:
We all know that PHP save errors in php_errors.log file.
But, that file contains a lot of data.
If we want to log our application data, we need to save it to a custom location.
We can use two parameters in the error_log function to achieve this.
http://php.net/manual/en/function.error-log.php
We can do it using:
error_log(print_r($v, TRUE), 3, '/var/tmp/errors.log');
Where,
print_r($v, TRUE) :
logs $v (array/string/object) to log file.
3
: Put log message to custom log file specified in the third parameter.
'/var/tmp/errors.log'
: Custom log file (This path is for Linux, we can specify other depending upon OS).
OR, you can use file_put_contents()
file_put_contents('/var/tmp/e.log', print_r($v, true), FILE_APPEND);
Where:
'/var/tmp/errors.log':
Custom log file (This path is for Linux, we can specify other depending upon OS).
print_r($v, TRUE) :
logs $v (array/string/object) to log file.
FILE_APPEND: Constant parameter specifying whether to append to the file if it exists, if file does not exist, new file will be created.
There are several ways to do this. I converted like this
def clean(s):
s = s.replace("u'","")
return re.sub("[\[\]\'\s]", '', s)
EmployeeList = [clean(i) for i in str(EmployeeList).split(',')]
After that you can check
if '1001' in EmployeeList:
#do something
Hope it will help you.
What you are looking for is a "diff algorithm". A quick google search led me to this solution. I did not test it, but maybe it will do what you need.
Use crosstab()
from the tablefunc module.
SELECT * FROM crosstab(
$$SELECT user_id, user_name, rn, email_address
FROM (
SELECT u.user_id, u.user_name, e.email_address
, row_number() OVER (PARTITION BY u.user_id
ORDER BY e.creation_date DESC NULLS LAST) AS rn
FROM usr u
LEFT JOIN email_tbl e USING (user_id)
) sub
WHERE rn < 4
ORDER BY user_id
$$
, 'VALUES (1),(2),(3)'
) AS t (user_id int, user_name text, email1 text, email2 text, email3 text);
I used dollar-quoting for the first parameter, which has no special meaning. It's just convenient if you have to escape single quotes in the query string which is a common case:
Detailed explanation and instructions here:
And in particular, for "extra columns":
The special difficulties here are:
The lack of key names.
-> We substitute with row_number()
in a subquery.
The varying number of emails.
-> We limit to a max. of three in the outer SELECT
and use crosstab()
with two parameters, providing a list of possible keys.
Pay attention to NULLS LAST
in the ORDER BY
.

You can also rename remote tags without checking them out, by duplicate the old tag/branch to a new name and delete the old one, in a single git push
command.
Remote tag rename / Remote branch ? tag conversion: (Notice: :refs/tags/
)
git push <remote_name> <old_branch_or_tag>:refs/tags/<new_tag> :<old_branch_or_tag>
Remote branch rename / Remote tag ? branch conversion: (Notice: :refs/heads/
)
git push <remote_name> <old_branch_or_tag>:refs/heads/<new_branch> :<old_branch_or_tag>
Output renaming a remote tag:
D:\git.repo>git push gitlab App%2012.1%20v12.1.0.23:refs/tags/App_12.1_v12.1.0.23 :App%2012.1%20v12.1.0.23

If it's a table-value function (returns a table set) you simply join it as a Table
this function generates one column table with all the values from passed comma-separated list

Zoom level 0 is the most zoomed out zoom level available and each integer step in zoom level halves the X and Y extents of the view and doubles the linear resolution.
Google Maps was built on a 256x256 pixel tile system where zoom level 0 was a 256x256 pixel image of the whole earth. A 256x256 tile for zoom level 1 enlarges a 128x128 pixel region from zoom level 0.
As correctly stated by bkaid, the available zoom range depends on where you are looking and the kind of map you are using:
Note that these values are for the Google Static Maps API which seems to give one more zoom level than the Javascript API. It appears that the extra zoom level available for Static Maps is just an upsampled version of the max-resolution image from the Javascript API.
Google Maps uses a Mercator projection so the scale varies substantially with latitude. A formula for calculating the correct scale based on latitude is:
meters_per_pixel = 156543.03392 * Math.cos(latLng.lat() * Math.PI / 180) / Math.pow(2, zoom)
Formula is from Chris Broadfoot's comment.
Google Maps basics
Zoom Level - zoom
0 - 19
0 lowest zoom (whole world)
19 highest zoom (individual buildings, if available) Retrieve current zoom level using mapObject.getZoom()
What you're looking for are the scales for each zoom level. Use these:
20 : 1128.497220
19 : 2256.994440
18 : 4513.988880

Go to Windows services in the control panel and start the MySQL service. For me it worked. When I was doing a Java EE project I got this error" Communication link failure". I restarted my system and then it worked.
After that I again got the same error even after restarting my system. Then I tried to open the MySQL command line console and login with root, even then it gave me an error.
Finally when I started the MySQL service from Windows services, it worked.
Take note of what is printed for x
. You are trying to convert an array (basically just a list) into an int. length-1
would be an array of a single number, which I assume numpy just treats as a float. You could do this, but it's not a purely-numpy solution.
EDIT: I was involved in a post a couple of weeks back where numpy was slower an operation than I had expected and I realised I had fallen into a default mindset that numpy was always the way to go for speed. Since my answer was not as clean as ayhan's, I thought I'd use this space to show that this is another such instance to illustrate that vectorize
is around 10% slower than building a list in Python. I don't know enough about numpy to explain why this is the case but perhaps someone else does?

Newest version has better support literally for any generated Makefiles, through the compiledb
Three steps:
install compiledb
pip install compiledb
run a dry make
compiledb -n make
(do the autogen, configure if needed)
there will be a compile_commands.json file generated open the project and you will see CLion will load info from the json file. If you your CLion still try to find CMakeLists.txt and cannot read compile_commands.json, try to remove the entire folder, re-download the source files, and redo step 1,2,3
Orignal post: Working with Makefiles in CLion using Compilation DB
Your json contains an array, but you're trying to parse it as an object.
This error occurs because objects must start with {
.
You have 2 options:
You can get rid of the ShopContainer
class and use Shop[]
instead
ShopContainer response = restTemplate.getForObject(
url, ShopContainer.class);
replace with
Shop[] response = restTemplate.getForObject(url, Shop[].class);
and then make your desired object from it.
You can change your server to return an object instead of a list
return mapper.writerWithDefaultPrettyPrinter().writeValueAsString(list);
replace with
return mapper.writerWithDefaultPrettyPrinter().writeValueAsString(
new ShopContainer(list));
Lambda expressions have a type of Action<parameters>
(in case they don't return a value) or Func<parameters,return>
(in case they have a return value). In your case you have two input parameters, and you need to return a value, so you should use:
Func<FullTimeJob, Student, FullTimeJob>
VAR1=value1 VAR2=value2 myScript args ...
DSO here means Dynamic Shared Object; since the error message says it's missing from the command line, I guess you have to add it to the command line.
That is, try adding -lpthread
to your command line.
The answer provided by @DSM is simple and straightforward, but I thought I'd add my own input to this question. If you look at the code for pandas.value_counts, you'll see that there is a lot going on.
If you need to calculate the frequency of many series, this could take a while. A faster implementation would be to use numpy.unique with return_counts = True
Here is an example:
import pandas as pd
import numpy as np
my_series = pd.Series([1,2,2,3,3,3])
print(my_series.value_counts())
3 3
2 2
1 1
dtype: int64
Notice here that the item returned is a pandas.Series
In comparison, numpy.unique
returns a tuple with two items, the unique values and the counts.
vals, counts = np.unique(my_series, return_counts=True)
print(vals, counts)
[1 2 3] [1 2 3]
You can then combine these into a dictionary:
results = dict(zip(vals, counts))
print(results)
{1: 1, 2: 2, 3: 3}
And then into a pandas.Series
print(pd.Series(results))
1 1
2 2
3 3
dtype: int64
I have the same warning (it's make my app cannot build). When I add C function
in Objective-C's .m file
, But forgot to declared it at .h
file.
The sql array type is not neccessary. Not if the element type is a primitive one. (Varchar, number, date,...)
Very basic sample:
declare
type TPidmList is table of sgbstdn.sgbstdn_pidm%type;
pidms TPidmList;
begin
select distinct sgbstdn_pidm
bulk collect into pidms
from sgbstdn
where sgbstdn_majr_code_1 = 'HS04'
and sgbstdn_program_1 = 'HSCOMPH';
-- do something with pidms
open :someCursor for
select value(t) pidm
from table(pidms) t;
end;
When you want to reuse it, then it might be interesting to know how that would look like. If you issue several commands than those could be grouped in a package. The private package variable trick from above has its downsides. When you add variables to a package, you give it state and now it doesn't act as a stateless bunch of functions but as some weird sort of singleton object instance instead.
e.g. When you recompile the body, it will raise exceptions in sessions that already used it before. (because the variable values got invalided)
However, you could declare the type in a package (or globally in sql), and use it as a paramter in methods that should use it.
create package Abc as
type TPidmList is table of sgbstdn.sgbstdn_pidm%type;
function CreateList(majorCode in Varchar,
program in Varchar) return TPidmList;
function Test1(list in TPidmList) return PLS_Integer;
-- "in" to make it immutable so that PL/SQL can pass a pointer instead of a copy
procedure Test2(list in TPidmList);
end;
create package body Abc as
function CreateList(majorCode in Varchar,
program in Varchar) return TPidmList is
result TPidmList;
begin
select distinct sgbstdn_pidm
bulk collect into result
from sgbstdn
where sgbstdn_majr_code_1 = majorCode
and sgbstdn_program_1 = program;
return result;
end;
function Test1(list in TPidmList) return PLS_Integer is
result PLS_Integer := 0;
begin
if list is null or list.Count = 0 then
return result;
end if;
for i in list.First .. list.Last loop
if ... then
result := result + list(i);
end if;
end loop;
end;
procedure Test2(list in TPidmList) as
begin
...
end;
return result;
end;
How to call it:
declare
pidms constant Abc.TPidmList := Abc.CreateList('HS04', 'HSCOMPH');
xyz PLS_Integer;
begin
Abc.Test2(pidms);
xyz := Abc.Test1(pidms);
...
open :someCursor for
select value(t) as Pidm,
xyz as SomeValue
from table(pidms) t;
end;
Don't forget to implement Serializable in every class your object will use like a list of objects. Else your app will crash.
Example:
public class City implements Serializable {
private List<House> house;
public List<House> getHouse() {
return house;
}
public void setHouse(List<House> house) {
this.house = house;
}}
Then House needs to implements Serializable as so :
public class House implements Serializable {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}}
Then you can use:
Bundle bundle = new Bundle();
bundle.putSerializable("city", city);
intent.putExtras(bundle);
And retreive it with:
Intent intent = this.getIntent();
Bundle bundle = intent.getExtras();
City city = (City)bundle.getSerializable("city");
The fundamental difference in most programming languages is that unless the unexpected happens a for
loop will always repeat n
times or until a break statement, (which may be conditional), is met then finish with a while
loop it may repeat 0 times, 1, more or even forever
, depending on a given condition which must be true at the start of each loop for it to execute and always false on exiting the loop, (for completeness a do ... while
loop, (or repeat until
), for languages that have it, always executes at least once and does not guarantee the condition on the first execution).
It is worth noting that in Python a for
or while
statement can have break
, continue
and else
statements where:
break
- terminates the loopcontinue
- moves on to the next time around the loop without executing following code this time aroundelse
- is executed if the loop completed without any break
statements being executed.N.B. In the now unsupported Python 2 range
produced a list of integers but you could use xrange
to use an iterator. In Python 3 range
returns an iterator.
So the answer to your question is 'it all depends on what you are trying to do'!
Label
is an inline element - so, unless a width is defined, its width is exact the same which the letters span. Your div
element is a block element so its width is by default 100%.
You will have to place the text-align: right;
on the div
element in your case, or applying display: block;
to your label
Another option is to set a width for each label and then use text-align
. The display: block
method will not be necessary using this.
Spent hours trying to fix the error for importing local modules. Code execution was fine but pylint showed:
Unable to import '<module>'
Finally figured:
First of all, select the correct python path. (In the case of a virtual environment, it will be venv/bin/python). You can do this by hitting
Make sure that your pylint path is the same as the python path you chose in step 1. (You can open VS Code from within the activated venv from terminal so it automatically performs these two steps)
The most important step: Add an empty __init__.py file in the folder that contains your module file. Although python3 does not require this file for importing modules, I think pylint still requires it for linting.
Restart VS Code, the errors should be gone!
You have to replace the values one by one such as in a for-loop or copying another array over another such as using memcpy(..)
or std::copy
e.g.
for (int i = 0; i < arrayLength; i++) {
array[i] = newValue[i];

Take care to ensure proper bounds-checking and any other checking that needs to occur to prevent an out of bounds problem.
I can't tell you what's best, but a tool I have used with success in the past was cx_Freeze. They recently updated (on Jan. 7, '17) to version 5.0.1 and it supports Python 3.6.
Here's the pypi https://pypi.python.org/pypi/cx_Freeze
The documentation shows that there is more than one way to do it, depending on your needs. http://cx-freeze.readthedocs.io/en/latest/overview.html
I have not tried it out yet, so I'm going to point to a post where the simple way of doing it was discussed. Some things may or may not have changed though.
String dt = Date.Now.ToString("yyyy-MM-dd");
Now you got this for dt, 2010-09-09
Just use percentage widths and fixed table layout:
<table>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
</table>
with
table { table-layout: fixed; }
td { width: 33%; }
Fixed table layout is important as otherwise the browser will adjust the widths as it sees fit if the contents don't fit ie the widths are otherwise a suggestion not a rule without fixed table layout.
Obviously, adjust the CSS to fit your circumstances, which usually means applying the styling only to a tables with a given class or possibly with a given ID.
From the man page:
search, -S text|/text/ Perform a substring search of formula names for text. If text is surrounded with slashes, then it is interpreted as a regular expression. If no search term is given, all available formula are displayed.
For your purposes, brew search
will suffice.
Have you tried libconfig; very JSON-like syntax. I prefer it over XML configuration files.
Wherever there is errors or exceptions in static blocks, this exception will be thrown. To get the cause of this exception simply use Throwable.getCause()
to know what is wrong.
For those who do want owin to start, <add key="owin:AutomaticAppStartup" value="false" />
won't work, but the following worked for me.
if you have a partial class "Startup" in your Startup.Auth file, create another partial Startup class in the root of your project.
define an assembly owinstartup attribute pointing to that class
create a "Configuration" method
rebuild your application
You could also create the "Configuration" method, and add the assembly attribute to the Startup.Auth, but doing it this way allows you to keep your Startup class separated by leveraging C# class definition splitting. Read more here: https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/partial-classes-and-methods
This is what my Startup.cs file looked like:
using Microsoft.Owin;
using Owin;
[assembly: OwinStartupAttribute(typeof(ProjectNameSpace.Startup))]
namespace ProjectNameSpace
{
public partial class Startup
{
public void Configuration(IAppBuilder app)
{
ConfigureAuth(app);
}
}
}
'data' should be a stringified JavaScript object:
data: JSON.stringify({ "userName": userName, "password" : password })
To send your formData
, pass it to stringify
:
data: JSON.stringify(formData)
Some servers also require the application/json
content type:
contentType: 'application/json'
There's also a more detailed answer to a similar question here: Jquery Ajax Posting json to webservice
There are three ways
let a = + '12';
let b = parseInt('12' , 10); // 10 means decimal number
let c = Number('12');
use these code for every image in select from SdCard or drewable to convert bitmap object.

DATE: It is used for values with a date part but no time part. MySQL retrieves and displays DATE values in YYYY-MM-DD format. The supported range is 1000-01-01
to 9999-12-31
.
DATETIME: It is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in YYYY-MM-DD HH:MM:SS format. The supported range is 1000-01-01 00:00:00
to 9999-12-31 23:59:59
.
TIMESTAMP: It is also used for values that contain both date and time parts, and includes the time zone. TIMESTAMP has a range of 1970-01-01 00:00:01
UTC to 2038-01-19 03:14:07
UTC.
TIME: Its values are in HH:MM:SS format (or HHH:MM:SS format for large hours values). TIME values may range from -838:59:59
to 838:59:59
. The hours part may be so large because the TIME type can be used not only to represent a time of day (which must be less than 24 hours), but also elapsed time or a time interval between two events (which may be much greater than 24 hours, or even negative).
I've made an attempt to implement a pull to refresh component, it's far from complete but demonstrates a possible implementation, https://github.com/johannilsson/android-pulltorefresh.
Main logic is implemented in PullToRefreshListView
that extends ListView
. Internally it controls the scrolling of a header view using The widget is now updated with support for 1.5 and later, please read the README for 1.5 support though.smoothScrollBy
(API Level 8).
In your layouts you simply add it like this.
<com.markupartist.android.widget.PullToRefreshListView
android:id="@+id/android:list"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
/>
Firstly, you should check if your image column is BLOB type!
I don't know anything about your SQL table, but if I'll try to make my own as an example.
We got fields id
(int), image
(blob) and image_name
(varchar(64)).
So the code should look like this (assume ID is always '1' and let's use this mysql_query):
$image = addslashes(file_get_contents($_FILES['image']['tmp_name'])); //SQL Injection defence!
$image_name = addslashes($_FILES['image']['name']);
$sql = "INSERT INTO `product_images` (`id`, `image`, `image_name`) VALUES ('1', '{$image}', '{$image_name}')";
if (!mysql_query($sql)) { // Error handling
echo "Something went wrong! :(";
}
You are doing it wrong in many ways. Don't use mysql functions - they are deprecated! Use PDO or MySQLi. You should also think about storing files locations on disk. Using MySQL for storing images is thought to be Bad Idea™. Handling SQL table with big data like images can be problematic.
Also your HTML form is out of standards. It should look like this:
<form action="insert_product.php" method="POST" enctype="multipart/form-data">
<label>File: </label><input type="file" name="image" />
<input type="submit" />
</form>
Sidenote:
When dealing with files and storing them as a BLOB, the data must be escaped using mysql_real_escape_string()
, otherwise it will result in a syntax error.
The above answer was helpful for me, but it might be useful (or best practice) to add the name on submit, as I wound up doing. Hopefully this will be helpful to someone. CodePen Sample
<form id="formAddName">
<fieldset>
<legend>Add Name </legend>
<label for="firstName">First Name</label>
<input type="text" id="firstName" name="firstName" />
<button>Add</button>
</fieldset>
</form>
<ol id="demo"></ol>
<script>
var list = document.getElementById('demo');
var entry = document.getElementById('formAddName');
entry.onsubmit = function(evt) {
evt.preventDefault();
var firstName = document.getElementById('firstName').value;
var entry = document.createElement('li');
entry.appendChild(document.createTextNode(firstName));
list.appendChild(entry);
}
</script>
solution is easy:
replace
mask = (50 < df['heart rate'] < 101 &
140 < df['systolic blood pressure'] < 160 &
90 < df['dyastolic blood pressure'] < 100 &
35 < df['temperature'] < 39 &
11 < df['respiratory rate'] < 19 &
95 < df['pulse oximetry'] < 100
, "excellent", "critical")
by
mask = ((50 < df['heart rate'] < 101) &
(140 < df['systolic blood pressure'] < 160) &
(90 < df['dyastolic blood pressure'] < 100) &
(35 < df['temperature'] < 39) &
(11 < df['respiratory rate'] < 19) &
(95 < df['pulse oximetry'] < 100)
, "excellent", "critical")
Try $("#divVideo video")[0].load();
after you changed the src attribute.
A slightly more efficient approach might be
Map<String, AtomicInteger> instances = new HashMap<String, AtomicInteger>();
void add(String name) {
AtomicInteger value = instances.get(name);
if (value == null)
instances.put(name, new AtomicInteger(1));
else
value.incrementAndGet();
}
I've got another way to add an or
condition in the field:
->addFieldToFilter(
array('title', 'content'),
array(
array('like'=>'%$titlesearchtext%'),
array('like'=>'%$contentsearchtext%')
)
)
Currently you can use it, changing the order: (it seems to be a bug)
Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
setSupportActionBar(toolbar);
toolbar.setNavigationIcon(R.drawable.ic_good);
toolbar.setTitle("Title");
toolbar.setSubtitle("Sub");
toolbar.setLogo(R.drawable.ic_launcher);
Add following lines to your .vimrc
set expandtab
set tabstop=4
set shiftwidth=4
map <F2> :retab <CR> :wq! <CR>
Open a file in vim and press F2 The tabs will be converted to 4 spaces and file will be saved automatically.
Use Max-Age=-1 rather than "Expires". It is shorter, less picky about the syntax, and Max-Age takes precedence over Expires anyway.
GoalSeek will throw an "Invalid Reference" error if the GoalSeek cell contains a value rather than a formula or if the ChangingCell contains a formula instead of a value or nothing.
The GoalSeek cell must contain a formula that refers directly or indirectly to the ChangingCell; if the formula doesn't refer to the ChangingCell in some way, GoalSeek either may not converge to an answer or may produce a nonsensical answer.
I tested your code with a different GoalSeek formula than yours (I wasn't quite clear whether some of the terms referred to cells or values).
For the test, I set:
the GoalSeek cell H18 = (G18^3)+(3*G18^2)+6
the Goal cell H32 = 11
the ChangingCell G18 = 0
The code was:
Sub GSeek()
With Worksheets("Sheet1")
.Range("H18").GoalSeek _
Goal:=.Range("H32").Value, _
ChangingCell:=.Range("G18")
End With
End Sub
And the code produced the (correct) answer of 1.1038, the value of G18 at which the formula in H18 produces the value of 11, the goal I was seeking.
You can use LINQ to DataSet/DataTable
var rows = dt.AsEnumerable()
.Where(r=> r.Field<int>("ID") == 5);
Since each row has a unique ID, you should use Single/SingleOrDefault
which would throw exception if you get multiple records back.
DataRow dr = dt.AsEnumerable()
.SingleOrDefault(r=> r.Field<int>("ID") == 5);
(Substitute int
for the type of your ID field)
Use the \
character to escape a character that has special meaning inside a regular expression.
To automate it, you could use this:
function escapeRegExp(text) {
return text.replace(/[-[\]{}()*+?.,\\^$|#\s]/g, '\\$&');
}
Update: There is now a proposal to standardize this method, possibly in ES2016: https://github.com/benjamingr/RegExp.escape
Update: The abovementioned proposal was rejected, so keep implementing this yourself if you need it.
As for me, most elegant way is yield break
For me, the problem was incorrect content type of the served .css file (if it included certain unicode characters).
Changing the content-type to text/css
solved the problem.
Firstly It tries insert. If there is a conflict on url
column then it updates content and last_analyzed fields. If updates are rare this might be better option.
INSERT INTO URLs (url, content, last_analyzed)
VALUES
(
%(url)s,
%(content)s,
NOW()
)
ON CONFLICT (url)
DO
UPDATE
SET content=%(content)s, last_analyzed = NOW();
You can check the implementation of CPython's dicttype
on GitHub. This is the signature of method that implements the dict iterator:
_PyDict_Next(PyObject *op, Py_ssize_t *ppos, PyObject **pkey,
PyObject **pvalue, Py_hash_t *phash)
With an already accepted answer present, I think this is a better answer to the question on how to handle this on the inventory level. I consider this more secure by isolating this insecure setting to the hosts required for this (e.g. test systems, local development machines).
What you can do at the inventory level is add
ansible_ssh_common_args='-o StrictHostKeyChecking=no'
or
ansible_ssh_extra_args='-o StrictHostKeyChecking=no'
to your host definition (see Ansible Behavioral Inventory Parameters).
This will work provided you use the ssh
connection type, not paramiko
or something else).
For example, a Vagrant host definition would look like…
vagrant ansible_port=2222 ansible_host=127.0.0.1 ansible_ssh_common_args='-o StrictHostKeyChecking=no'
or
vagrant ansible_port=2222 ansible_host=127.0.0.1 ansible_ssh_extra_args='-o StrictHostKeyChecking=no'
Running Ansible will then be successful without changing any environment variable.
$ ansible vagrant -i <path/to/hosts/file> -m ping
vagrant | SUCCESS => {
"changed": false,
"ping": "pong"
}
In case you want to do this for a group of hosts, here's a suggestion to make it a supplemental group var for an existing group like this:
[mytestsystems]
test[01:99].example.tld
[insecuressh:children]
mytestsystems
[insecuressh:vars]
ansible_ssh_common_args='-o StrictHostKeyChecking=no'
I work with asp.net core 2.2 and jquery and have to submit a complex object ('main class') from a view to a controller with simple data fields and some array's.
As soon as I have added the array in the c# 'main class' definition (see below) and submitted the (correct filled) array over ajax (post), the whole object was null in the controller.
First, I thought, the missing "traditional: true," to my ajax call was the reason, but this is not the case.
In my case the reason was the definition in the c# 'main class'.
In the 'main class', I had:
public List<EreignisTagNeu> oEreignistageNeu { get; set; }
and EreignisTagNeu was defined as:
public class EreignisTagNeu
{
public int iHME_Key { get; set; }
}
I had to change the definition in the 'main class' to:
public List<int> oEreignistageNeu { get; set; }
Now it works.
So... for me it seems as asp.net core has a problem (with post), if the list for an array is not defined completely in the 'main class'.
Note:
In my case this works with or without "traditional: true," to the ajax call
You can do this with far less code:
function callPlayer(func, args) {
var i = 0,
iframes = document.getElementsByTagName('iframe'),
src = '';
for (i = 0; i < iframes.length; i += 1) {
src = iframes[i].getAttribute('src');
if (src && src.indexOf('youtube.com/embed') !== -1) {
iframes[i].contentWindow.postMessage(JSON.stringify({
'event': 'command',
'func': func,
'args': args || []
}), '*');
}
}
}
Working example: http://jsfiddle.net/kmturley/g6P5H/296/
If it's just a library that's causing this, this will avoid the problem just fine. Typescript can be a pain on the neck sometimes so set this value on your tsconfig.json file.

If you have an abstract URL string (not from the current window.location
), you can use this trick:
let yourUrlString = "http://example.com:3000/pathname/?search=test#hash";
let parser = document.createElement('a');
parser.href = yourUrlString;
parser.protocol; // => "http:"
parser.hostname; // => "example.com"
parser.port; // => "3000"
parser.pathname; // => "/pathname/"
parser.search; // => "?search=test"
parser.hash; // => "#hash"
parser.host; // => "example.com:3000"

Python really tries hard to intelligently set sys.path
. How it is
set can get really complicated. The following guide is a watered-down,
somewhat-incomplete, somewhat-wrong, but hopefully-useful guide
for the rank-and-file python programmer of what happens when python
figures out what to use as the initial values of sys.path
,
sys.executable
, sys.exec_prefix
, and sys.prefix
on a normal
python installation.
First, python does its level best to figure out its actual physical
location on the filesystem based on what the operating system tells
it. If the OS just says "python" is running, it finds itself in $PATH.
It resolves any symbolic links. Once it has done this, the path of
the executable that it finds is used as the value for sys.executable
, no ifs,
ands, or buts.
Next, it determines the initial values for sys.exec_prefix
and
sys.prefix
.
If there is a file called pyvenv.cfg
in the same directory as
sys.executable
or one directory up, python looks at it. Different
OSes do different things with this file.
One of the values in this config file that python looks for is
the configuration option home = <DIRECTORY>
. Python will use this directory instead of the directory containing sys.executable
when it dynamically sets the initial value of sys.prefix
later. If the applocal = true
setting appears in the
pyvenv.cfg
file on Windows, but not the home = <DIRECTORY>
setting,
then sys.prefix
will be set to the directory containing sys.executable
.
Next, the PYTHONHOME
environment variable is examined. On Linux and Mac,
sys.prefix
and sys.exec_prefix
are set to the PYTHONHOME
environment variable, if
it exists, superseding any home = <DIRECTORY>
setting in pyvenv.cfg
. On Windows,
sys.prefix
and sys.exec_prefix
is set to the PYTHONHOME
environment variable,
if it exists, unless a home = <DIRECTORY>
setting is present in pyvenv.cfg
,
which is used instead.
Otherwise, these sys.prefix
and sys.exec_prefix
are found by walking backwards
from the location of sys.executable
, or the home
directory given by pyvenv.cfg
if any.
If the file lib/python<version>/dyn-load
is found in that directory
or any of its parent directories, that directory is set to be to be
sys.exec_prefix
on Linux or Mac. If the file
lib/python<version>/os.py
is is found in the directory or any of its
subdirectories, that directory is set to be sys.prefix
on Linux,
Mac, and Windows, with sys.exec_prefix
set to the same value as
sys.prefix
on Windows. This entire step is skipped on Windows if
applocal = true
is set. Either the directory of sys.executable
is
used or, if home
is set in pyvenv.cfg
, that is used instead for
the initial value of sys.prefix
.
If it can't find these "landmark" files or sys.prefix
hasn't been
found yet, then python sets sys.prefix
to a "fallback"
value. Linux and Mac, for example, use pre-compiled defaults as the
values of sys.prefix
and sys.exec_prefix
. Windows waits
until sys.path
is fully figured out to set a fallback value for
sys.prefix
.
Then, (what you've all been waiting for,) python determines the initial values
that are to be contained in sys.path
.
sys.path
.
On Windows, this is always the empty string, which tells python to
use the full path where the script is located instead.sys.path
, unless you're
on Windows and applocal
is set to true in pyvenv.cfg
.<prefix>/lib/python35.zip
on Linux/Mac and
os.path.join(os.dirname(sys.executable), "python.zip")
on Windows, is added to sys.path
.applocal = true
was set in pyvenv.cfg
, then the contents of the subkeys of the registry key
HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\
are added, if any.applocal = true
was set in pyvenv.cfg
, and sys.prefix
could not be found,
then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\
is added, if it exists;applocal = true
was set in pyvenv.cfg
, then the contents of the subkeys of the registry key
HK_LOCAL_MACHINE\Software\Python\PythonCore\<DLLVersion>\PythonPath\
are added, if any.applocal = true
was set in pyvenv.cfg
, and sys.prefix
could not be found,
then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\
is added, if it exists;sys.prefix
.sys.exec_prefix
is added. On Windows, the directory
which was used (or would have been used) to search dynamically for sys.prefix
is
added.At this stage on Windows, if no prefix was found, then python will try to
determine it by searching all the directories in sys.path
for the landmark files,
as it tried to do with the directory of sys.executable
previously, until it finds something.
If it doesn't, sys.prefix
is left blank.
Finally, after all this, Python loads the site
module, which adds stuff yet further to sys.path
:
It starts by constructing up to four directories from a head and a tail part. For the head part, it uses
sys.prefix
andsys.exec_prefix
; empty heads are skipped. For the tail part, it uses the empty string and thenlib/site-packages
(on Windows) orlib/pythonX.Y/site-packages
and thenlib/site-python
(on Unix and Macintosh). For each of the distinct head-tail combinations, it sees if it refers to an existing directory, and if so, adds it to sys.path and also inspects the newly added path for configuration files.
When in doubt, read the documentation:
filename = "C:\Temp\vblist.txt"
Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)
Do Until f.AtEndOfStream
WScript.Echo f.ReadLine
Loop
f.Close
What about this trick...
ls -lrt -d -1 $PWD/{*,.*}
OR
ls -lrt -d -1 $PWD/*
I think this has problems with empty directories but if another poster has a tweak I'll update my answer. Also, you may already know this but this is probably be a good candidate for an alias given it's lengthiness.
[update] added some tweaks based on comments, thanks guys.
[update] as pointed out by the comments you may need to tweek the matcher expressions depending on the shell (bash vs zsh). I've re-added my older command for reference.
It's a long pointer to a constant, wide string (i.e. a string of wide characters).
Since it's a wide string, you want to make your constant look like: L"TestWindow"
. I wouldn't create the intermediate a
either, I'd just pass L"TestWindow"
for the parameter:
ghTest = FindWindowEx(NULL, NULL, NULL, L"TestWindow");
If you want to be pedantically correct, an "LPCTSTR" is a "text" string -- a wide string in a Unicode build and a narrow string in an ANSI build, so you should use the appropriate macro:
ghTest = FindWindow(NULL, NULL, NULL, _T("TestWindow"));
Few people care about producing code that can compile for both Unicode and ANSI character sets though, and if you don't getting it to really work correctly can be quite a bit of extra work for little gain. In this particular case, there's not much extra work, but if you're manipulating strings, there's a whole set of string manipulation macros that resolve to the correct functions.
IF you want to select object with minimum or maximum property value. another way is to use Implementing IComparable.
public struct Money : IComparable<Money>
{
public Money(decimal value) : this() { Value = value; }
public decimal Value { get; private set; }
public int CompareTo(Money other) { return Value.CompareTo(other.Value); }
}
Max Implementation will be.
var amounts = new List<Money> { new Money(20), new Money(10) };
Money maxAmount = amounts.Max();
Min Implementation will be.
var amounts = new List<Money> { new Money(20), new Money(10) };
Money maxAmount = amounts.Min();
In this way, you can compare any object and get the Max and Min while returning the object type.
Hope This will help someone.
How about..
>>> line = r'path=c:\path'
>>> line.partition('path=')
('', 'path=', 'c:\\path')
This triplet is the head, separator, and tail.
This answer is not accurate because it mix description of UTM and UTM itself (Universal Turing Machine).
We have good answer but from different perspective and it do not show directly flaws in current top answer.
First of all we can agree that human can work as UTM. This mean if we do
CSS + Human == UTM
Then CSS
part is useless because all work can be done by Human
who will do UTM part. Act of clicking can be UTM, because you do not click at random but only in specific places.
Instead of CSS I could use this text (Rule 110):
000 -> 0
001 -> 1
010 -> 1
011 -> 1
100 -> 0
101 -> 1
110 -> 1
111 -> 0
To guide my actions and result will be same. This mean this text UTM? No this is only input (description) that other UTM (human or computer) can read and run. Clicking is enough to run any UTM.
Critical part that CSS lack is ability to change of it own state in arbitrary way, if CSS could generate clicks then it would be UTM. Argument that your clicks are "crank" for CSS is not accurate because real "crank" for CSS is Layout Engine that run it and it should be enough to prove that CSS is UTM.
$IFS
comment hacksThis hack uses parameter expansion on $IFS
, which is used to separate words in commands:
$ echo foo${IFS}bar
foo bar
Similarly:
$ echo foo${IFS#comment}bar
foo bar
Using this, you can put a comment on a command line with contination:
$ echo foo${IFS# Comment here} \
> bar
foo bar
but the comment will need to be before the \
continuation.
Note that parameter expansion is performed inside the comment:
$ ls file
ls: cannot access 'file': No such file or directory
$ echo foo${IFS# This command will create file: $(touch file)}bar
foo bar
$ ls file
file
Rare exception
The only rare case this fails is if $IFS
previously started with the exact text which is removed via the expansion (ie, after the #
character):
$ IFS=x
$ echo foo${IFS#y}bar
foo bar
$ echo foo${IFS#x}bar
foobar
Note the final foobar
has no space, illustrating the issue.
Since $IFS
contains only whitespace by default, it's extremely unlikely you'll run into this problem.
Credit to @pjh's comment which sparked off this answer.
Sure, use the .format method. E.g.,
print('{:10s} {:3d} {:7.2f}'.format('xxx', 123, 98))
print('{:10s} {:3d} {:7.2f}'.format('yyyy', 3, 1.0))
print('{:10s} {:3d} {:7.2f}'.format('zz', 42, 123.34))
will print
xxx 123 98.00
yyyy 3 1.00
zz 42 123.34
You can adjust the field sizes as desired. Note that .format
works independently of print
to format a string. I just used print to display the strings. Brief explanation:
10s
format a string with 10 spaces, left justified by default
3d
format an integer reserving 3 spaces, right justified by default
7.2f
format a float, reserving 7 spaces, 2 after the decimal point, right justfied by default.
There are many additional options to position/format strings (padding, left/right justify etc), String Formatting Operations will provide more information.
Update for f-string mode. E.g.,
text, number, other_number = 'xxx', 123, 98
print(f'{text:10} {number:3d} {other_number:7.2f}')
For right alignment
print(f'{text:>10} {number:3d} {other_number:7.2f}')
CREATE TABLE `voting` (
`QuestionID` int(10) unsigned NOT NULL,
`MemberId` int(10) unsigned NOT NULL,
`vote` int(10) unsigned NOT NULL,
PRIMARY KEY (`QuestionID`,`MemberId`)
);
I had same error and the mistake was that I had added list and dictionary into the same list (object) and when I used to iterate over the list of dictionaries and use to hit a list (type) object then I used to get this error.
Its was a code error and made sure that I only added dictionary objects to that list and list typed object into the list, this solved my issue as well.
I finally found out how to do this! Basically you need to run adb shell
first and then while you're in the shell run su
, which will switch the shell to run as root!
$: adb shell
$: su
The one problem I still have is that sqlite3 is not installed so the command is not recognized.
Assuming you have a field for DateTime
, you could have your query look like this:
SELECT *
FROM TABLE
WHERE DateTime > (GetDate() + 90)
With only css, you can define two css classes.
<style type="text/css">
/* Over the pointer-events:none, set the cursor to not-allowed.
On this way you will have a more user friendly cursor. */
.disabledTab {
cursor: not-allowed;
}
/* Clicks are not permitted and change the opacity. */
li.disabledTab > a[data-toggle="tab"] {
pointer-events: none;
filter: alpha(opacity=65);
-webkit-box-shadow: none;
box-shadow: none;
opacity: .65;
}
</style>
This is an html template. The only thing needed is to set the class to your preferred list item.
<ul class="nav nav-tabs tab-header">
<li>
<a href="#tab-info" data-toggle="tab">Info</a>
</li>
<li class="disabledTab">
<a href="#tab-date" data-toggle="tab">Date</a>
</li>
<li>
<a href="#tab-photo" data-toggle="tab">Photo</a>
</li>
</ul>
<div class="tab-content">
<div class="tab-pane active" id="tab-info">Info</div>
<div class="tab-pane active" id="tab-date">Date</div>
<div class="tab-pane active" id="tab-photo">Photo</div>

You can change the working directory with:
import os
os.chdir(path)
There are two best practices to follow when using this method:
Changing the current working directory in a subprocess does not change the current working directory in the parent process. This is true of the Python interpreter as well. You cannot use os.chdir()
to change the CWD of the calling process.
Actually emberjs
supports two-way binding, which is one of the most powerful feature for a javascript MVC framework. You can check it out where it mentioning binding
in its user guide.
for emberjs, to create two way binding is by creating a new property with the string Binding at the end, then specifying a path from the global scope:
App.wife = Ember.Object.create({
householdIncome: 80000
});
App.husband = Ember.Object.create({
householdIncomeBinding: 'App.wife.householdIncome'
});
App.husband.get('householdIncome'); // 80000
// Someone gets raise.
App.husband.set('householdIncome', 90000);
App.wife.get('householdIncome'); // 90000
Note that bindings don't update immediately. Ember waits until all of your application code has finished running before synchronizing changes, so you can change a bound property as many times as you'd like without worrying about the overhead of syncing bindings when values are transient.
Hope it helps in extend of original answer selected.
I like to use this simple method to get the selected values and join them into a string
private string JoinCBLSelectedValues(CheckBoxList cbl, string separator = "")
{
return string.Join(separator, cbl.Items.Cast<ListItem>().Where(li => li.Selected).ToList());
}
The following should work. The lambda function filter out the duplicated words.
inputs=[]
input = raw_input("Word: ").strip()
while input:
inputs.append(input)
input = raw_input("Word: ").strip()
uniques=reduce(lambda x,y: ((y in x) and x) or x+[y], inputs, [])
print 'There are', len(uniques), 'unique words'
None of the advanced answers to this question resolved the problem for me.

with this piece of code you can achieve this, easily. Tested code
You can use from the pd.to_numeric(s)
You can simply do:
"123456".Select(q => new string(q,1)).ToArray();
to have an enumerable of integers, as per comment request, you can:
"123456".Select(q => int.Parse(new string(q,1))).ToArray();
It is a little weak since it assumes the string actually contains numbers.
If boolean() is not available (the tool I'm using does not) one way to achieve it is:
//SELECT[@id='xpto']/OPTION[not(not(@selected))]
In this case, within the /OPTION, one of the options is the selected one. The "selected" does not have a value... it just exists, while the other OPTION do not have "selected". This achieves the objective.
believe there should be a way in accessing file system.
Include node.d.ts
using npm i @types/node
. And then create a new tsconfig.json
file (npx tsc --init
) and create a .ts
file as followed:
import fs from 'fs';
fs.readFileSync('foo.txt','utf8');
You can use other functions in fs
as well : https://nodejs.org/api/fs.html

Just a tip: using http_response_code is much easier to remember than writing the full header:
http_response_code(301);
header('Location: /option-a');
exit;
I hope to provide more background knowledge here.
First, constructor signature of the of method threading::Thread:
class threading.Thread(group=None, target=None, name=None, args=(), kwargs={}, *, daemon=None)
args is the argument tuple for the target invocation. Defaults to ().
Second, A quirk in Python about tuple
:
Empty tuples are constructed by an empty pair of parentheses; a tuple with one item is constructed by following a value with a comma (it is not sufficient to enclose a single value in parentheses).
On the other hand, a string is a sequence of characters, like 'abc'[1] == 'b'
. So if send a string to args
, even in parentheses (still a sting), each character will be treated as a single parameter.
However, Python is so integrated and is not like JavaScript where extra arguments can be tolerated. Instead, it throws an TypeError
to complain.
Function map is a good choice when dealing with object arrays. Although there have been a number of good answers posted already, the example of using map with combination with filter might be helpful.
In case you want to exclude the properties which values are undefined or exclude just a specific property, you could do the following:
var obj = {value1: "val1", value2: "val2", Ndb_No: "testing", myVal: undefined};
var keysFiltered = Object.keys(obj).filter(function(item){return !(item == "Ndb_No" || obj[item] == undefined)});
var valuesFiltered = keysFiltered.map(function(item) {return obj[item]});
In conclusion, Here give more common way that include return value or void, and throw
import Foundation
extension NSObject {
func synchronized<T>(lockObj: AnyObject!, closure: () throws -> T) rethrows -> T
{
objc_sync_enter(lockObj)
defer {
objc_sync_exit(lockObj)
}
return try closure()
}
}
Console.WriteLine(dt2 != null ? dt2.Value.ToString("yyyy-MM-dd hh:mm:ss") : "n/a");
EDIT: As stated in other comments, check that there is a non-null value.
Update: as recommended in the comments, extension method:
public static string ToString(this DateTime? dt, string format)
=> dt == null ? "n/a" : ((DateTime)dt).ToString(format);
And starting in C# 6, you can use the null-conditional operator to simplify the code even more. The expression below will return null if the DateTime?
is null.
dt2?.ToString("yyyy-MM-dd hh:mm:ss")
Adding to @adardesign
's answer, if you want to reset all files that have been added to assume-unchanged
list to no-assume-unchanged
in one go, you can do the following:
git ls-files -v | grep '^h' | sed 's/^..//' | sed 's/\ /\\ /g' | xargs -I FILE git update-index --no-assume-unchanged FILE || true
This will just strip out the two characters output from grep i.e. "h "
, then escape any spaces that may be present in file names, and finally || true
will prevent the command to terminate prematurely in case some files in the loop has errors.
You can try
lstCountry.SelectedItem.Text
Limit words in text:
function limitTextWords($content = false, $limit = false, $stripTags = false, $ellipsis = false)
{
if ($content && $limit) {
$content = ($stripTags ? strip_tags($content) : $content);
$content = explode(' ', $content, $limit+1);
array_pop($content);
if ($ellipsis) {
array_push($content, '...');
}
$content = implode(' ', $content);
}
return $content;
}
Limit chars in text:
function limitTextChars($content = false, $limit = false, $stripTags = false, $ellipsis = false)
{
if ($content && $limit) {
$content = ($stripTags ? strip_tags($content) : $content);
$ellipsis = ($ellipsis ? "..." : $ellipsis);
$content = mb_strimwidth($content, 0, $limit, $ellipsis);
}
return $content;
}
Use:
$text = "It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout.";
echo limitTextWords($text, 5, true, true);
echo limitTextChars($text, 5, true, true);
Another example; using JavaScript to set a selected option.
(You could use this example to for loop an array of values into a drop down component)
<select id="yourDropDownElementId"><select/>
// Get the select element
var select = document.getElementById("yourDropDownElementId");
// Create a new option element
var el = document.createElement("option");
// Add our value to the option
el.textContent = "Example Value";
el.value = "Example Value";
// Set the option to selected
el.selected = true;
// Add the new option element to the select element
select.appendChild(el);
I've created a (German) description how to get it working. You basically need an emulator with at least API level 9 and no Google APIs. Then you'll have to get the APKs from a rooted device:
adb -d pull /data/app/com.android.vending-2.apk
adb -d pull /data/app/com.google.android.gms-2.apk
and install them in the emulator:
adb -e install com.android.vending-2.apk
adb -e install com.google.android.gms-2.apk
You can even run the native Google Maps App, if you have an emulator with at least API level 14 and additionally install com.google.android.apps.maps-1.apk
Have fun.
Easily Display Line number:
set number flag (to show line number type)
:set nu
or :set number
to unset the number flag (hide the line number type)
:set nu!
If you need number every time you start vi/vim
, append following line to your ~/.vimrc
file:
set number
Open a file at particular location/line number
$ vi +linenumber file.rb
$ vi +300 initlib.rb
another approach is to use the double colons:
mtcars %>%
dplyr::group_by(cyl, gear) %>%
dplyr::summarise(length(gear))
I prefer the response helper myself:
return response()->json(['message' => 'Yup. This request succeeded.'], 200);
UPDATE: This changes in npm v7 due to npm RFC 21.
npm (and yarn) passes a lot of data from package.json into scripts as environment variables. Use npm run env
to see them all. This is documented in https://docs.npmjs.com/misc/scripts#environment and is not only for "lifecycle" scripts like prepublish
but also any script executed by npm run
.
You can access these inside code (e.g. process.env.npm_package_config_port
in JS) but they're already available to the shell running the scripts so you can also access them as $npm_...
expansions in the "scripts" (unix syntax, might not work on windows?).
The "config" section seems intended for this use:
"name": "myproject",
...
"config": {
"port": "8010"
},
"scripts": {
"start": "node server.js $npm_package_config_port",
"test": "wait-on http://localhost:$npm_package_config_port/ && node test.js http://localhost:$npm_package_config_port/"
}
An important quality of these "config" fields is that users can override them without modifying package.json!
$ npm run start
> [email protected] start /home/cben/mydir
> node server.js $npm_package_config_port
Serving on localhost:8010
$ npm config set myproject:port 8020
$ git diff package.json # no change!
$ cat ~/.npmrc
myproject:port=8020
$ npm run start
> [email protected] start /home/cben/mydir
> node server.js $npm_package_config_port
Serving on localhost:8020
See npm config and yarn config docs.
It appears that yarn reads ~/.npmrc
so npm config set
affects both, but yarn config set
writes to ~/.yarnrc
, so only yarn will see it :-(
Huffman has a static cost, the Huffman table, so I disagree it's a good choice.
There are adaptative versions which do away with this, but the compression rate may suffer. Actually, the question you should ask is "what algorithm to compress text strings with these characteristics". For instance, if long repetitions are expected, simple Run-Lengh Encoding might be enough. If you can guarantee that only English words, spaces, punctiation and the occasional digits will be present, then Huffman with a pre-defined Huffman table might yield good results.
Generally, algorithms of the Lempel-Ziv family have very good compression and performance, and libraries for them abound. I'd go with that.
With the information that what's being compressed are URLs, then I'd suggest that, before compressing (with whatever algorithm is easily available), you CODIFY them. URLs follow well-defined patterns, and some parts of it are highly predictable. By making use of this knowledge, you can codify the URLs into something smaller to begin with, and ideas behind Huffman encoding can help you here.
For example, translating the URL into a bit stream, you could replace "http" with the bit 1, and anything else with the bit "0" followed by the actual procotol (or use a table to get other common protocols, like https, ftp, file). The "://" can be dropped altogether, as long as you can mark the end of the protocol. Etc. Go read about URL format, and think on how they can be codified to take less space.
You are dividing by rr
which may be 0.0. Check if rr
is zero and do something reasonable other than using it in the denominator.
Try this below code it is also works well in angular 2
<span>{{current_date | date: 'yyyy-MM-dd'}}</span>

Thanks Hong, that was exactly the problem I was running into. The error you get suggests that the number of rows is wrong, but the problem is actually that the model has been trained using a command that ends up with the wrong names for parameters.
This is really a critical detail that is entirely non-obvious for lm and so on. Some of the tutorial make reference to doing lines like lm(olive$Area@olive$Palmitic)
- ending up with variable names of olive$Area NOT Area, so creating an entry using anewdata<-data.frame(Palmitic=2)
can't then be used. If you use lm(Area@Palmitic,data=olive)
then the variable names are right and prediction works.
The real problem is that the error message does not indicate the problem at all:
Warning message: 'anewdata' had 1 rows but variable(s) found to have X rows
If you need to show short date and time (11/08/2018 03:23 a.m.) you can do it like this:
{{your_date_field|date:"SHORT_DATE_FORMAT"}} {{your_date_field|time:"h:i a"}}
Details for this tag here and more about dates according to the given format here
Example:
<small class="text-muted">Last updated: {{your_date_field|date:"SHORT_DATE_FORMAT"}} {{your_date_field|time:"h:i a"}}</small>
You can use a basic prepend operation on each line:
ls -1 | while read line ; do echo $line ; done
Or you can pipe the output to sed for more complex operations:
ls -1 | sed 's/^\(.*\)$/echo \1/'
TimeZone timeZone = TimeZone.getDefault();
timeZone.getID();
It will print like
Asia/Kolkata
Here is the simple solution by StreamEx:
StreamEx.of(list).groupingBy(Function.identity(), MoreCollectors.countingInt());
This has the advantage of reducing the Java stream boilerplate code: collect(Collectors.
If you are using Java for OpenCV, then you can use the following code.
Mat img = src.clone(); //Clone from the original image
img.setTo(new Scalar(255,255,255)); //This sets the whole image to white, it is R,G,B value

I'd recommend using a class instead of setting css properties. So instead of this:
$(this).css({"border-color": "#C1E0FF",
"border-width":"1px",
"border-style":"solid"});
Define a css class:
.border
{
border-color: #C1E0FF;
border-width:1px;
border-style:solid;
}
And then change your javascript to:
$(this).addClass("border");
You have to use the following code in order to update the scope of the specific input model as follows
$('button').on('click', function(){
var newVal = $(this).data('val');
$('select').val(newVal).change();
var scope = angular.element($("select")).scope();
scope.$apply(function(){
scope.selectValue = newVal;
});
});
you are doing several things wrong. The explanation follows the corrected code:
<label id="LblTextCount"></label>
<textarea name="text" onKeyPress="checkLength(this, 512, 'LblTextCount')">
</textarea>
Note the quotes around the id.
function checkLength(object, maxlength, label) {
charsleft = (maxlength - object.value.length);
// never allow to exceed the specified limit
if( charsleft < 0 ) {
object.value = object.value.substring(0, maxlength-1);
}
// set the value of charsleft into the label
document.getElementById(label).innerHTML = charsleft;
}
First, on your key press event you need to send the label id as a string for it to read correctly. Second, InnerHTML has a lowercase i. Lastly, because you sent the function the string id you can get the element by that id.
Let me know how that works out for you
EDIT Not that by not declaring charsleft as a var, you are implicitly creating a global variable. a better way would be to do the following when declaring it in the function:
var charsleft = ....
You can download the wheel corresponding to your configuration here ("Pillow-4.1.1-cp36-cp36m-win_amd64.whl" in your case) and install it with:
pip install some-package.whl
If you have problem to install the wheel read this answer
@AbdulRahim answer is almost correct. But I suggest the function below as substitute (for futher reference):
function getXY(evt, element) {
var rect = element.getBoundingClientRect();
var scrollTop = document.documentElement.scrollTop?
document.documentElement.scrollTop:document.body.scrollTop;
var scrollLeft = document.documentElement.scrollLeft?
document.documentElement.scrollLeft:document.body.scrollLeft;
var elementLeft = rect.left+scrollLeft;
var elementTop = rect.top+scrollTop;
x = evt.pageX-elementLeft;
y = evt.pageY-elementTop;
return {x:x, y:y};
}
$('#main-canvas').mousemove(function(e){
var m=getXY(e, this);
console.log(m.x, m.y);
});
I have had this error when connecting to a RabbitMQ MQTT server via TLS. I'm pretty sure the server is broken but anyway it worked with OpenSSL 1.0.1, but not OpenSSL 1.0.2.
You can check your version in Python using this:
import ssl
ssl.OPENSSL_VERSION
I'm not sure how to downgrade OpenSSL within Python (it seems to be statically linked on Windows at least), other than using an older version of Python.
If the column has the NOT NULL
constraint then it won't be possible; but otherwise this is fine:
INSERT INTO MyTable(MyIntColumn) VALUES(NULL);
Using MySQL inbuilt function group_concat() will be a good choice for getting the desired result. The syntax will be -
SELECT group_concat(STRINGVALUE)
FROM Jira.customfieldvalue
WHERE CUSTOMFIELD = 12534
AND ISSUE = 19602
Before you execute the above command make sure you increase the size of group_concat_max_len else the the whole output may not fit in that cell.
To set the value of group_concat_max_len, execute the below command-
SET group_concat_max_len = 50000;
You can change the value 50000 accordingly, you increase it to a higher value as required.
i was having the same issue while generating the classes from wsimport goal. Instead of using jaxws:wsimport goal in eclipse Maven Build i was using clean compile install that was not able to generate code from wsdl file. Thanks to above example. Run jaxws:wsimport goal from Eclipse ide and it will work
Whenever slicing (a:n
) can be used, it can be replaced by fancy indexing (e.g. [a,b,c,...,n]
). Fancy indexing is nothing more than listing explicitly all the index values instead of specifying only the limits.
Whenever fancy indexing can be used, it can be replaced by a list of Boolean values (a mask) the same size than the index. The value will be True
for index values that would have been included in the fancy index, and False
for the values that would have been excluded. It's another way of listing some index values, but which can be easily automated in NumPy and Pandas, e.g by a logical comparison (like in your case).
The second replacement possibility is the one used in your example. In:
iris_data.loc[iris_data['class'] == 'versicolor', 'class'] = 'Iris-versicolor'
the mask
iris_data['class'] == 'versicolor'
is a replacement for a long and silly fancy index which would be list of row numbers where class
column (a Series) has the value versicolor
.
Whether a Boolean mask appears within a .iloc
or .loc
(e.g. df.loc[mask]
) indexer or directly as the index (e.g. df[mask]
) depends on wether a slice is allowed as a direct index. Such cases are shown in the following indexer cheat-sheet:
Xcode 8 bug…
Try this first if your Storyboard UITableView style is set to Plain.
Set the table's style to Grouped and then back to Plain. This removed the space in my app at the head of my UITableView.
Answer above did not work for me on Chrome. The change event was been fired after I clicked out of the field somewhere, which did not help because the datepicker window is also closed too when you click out of the field.
I did use this code and it worked pretty well. You can place it after calling .datepicker();
HTML
<input type="text" class="datepicker-input" placeholder="click to show datepicker" />
JavaScript
$(".datepicker-input").each(function() {
$(this).datepicker();
});
$(".datepicker-input").click(function() {
$(".datepicker-days .day").click(function() {
$('.datepicker').hide();
});
});
Put this in your .vimrc configuration file.
