First of all, I don't really see why you would want an object having only ID and Version, and all other props to be nulls. However, here is some code which will do that for you (which doesn't use JPA Em, but normal Hibernate. I assume you can find the equivalence in JPA or simply obtain the Hibernate Session obj from the em delegate Accessing Hibernate Session from EJB using EntityManager ):
List<T> results = session.createCriteria(entityClazz)
.setProjection( Projections.projectionList()
.add( Property.forName("ID") )
.add( Property.forName("VERSION") )
)
.setResultTransformer(Transformers.aliasToBean(entityClazz);
.list();
This will return a list of Objects having their ID and Version set and all other props to null, as the aliasToBean transformer won't be able to find them. Again, I am uncertain I can think of a situation where I would want to do that.
A very simple hack is to use the json import instead of csv. For example instead of csv.writer just do the following:
fd = codecs.open(tempfilename, 'wb', 'utf-8')
for c in whatever :
fd.write( json.dumps(c) [1:-1] ) # json dumps writes ["a",..]
fd.write('\n')
fd.close()
Basically, given the list of fields in correct order, the json formatted string is identical to a csv line except for [ and ] at the start and end respectively. And json seems to be robust to utf-8 in python 2.*
Another question asked specifically how to perform multiple left joins using dplyr in R . The question was marked as a duplicate of this one so I answer here, using the 3 sample data frames below:
x <- data.frame(i = c("a","b","c"), j = 1:3, stringsAsFactors=FALSE)
y <- data.frame(i = c("b","c","d"), k = 4:6, stringsAsFactors=FALSE)
z <- data.frame(i = c("c","d","a"), l = 7:9, stringsAsFactors=FALSE)
Update June 2018: I divided the answer in three sections representing three different ways to perform the merge. You probably want to use the purrr
way if you are already using the tidyverse packages. For comparison purposes below, you'll find a base R version using the same sample dataset.
1) Join them with reduce
from the purrr
package:
The purrr
package provides a reduce
function which has a concise syntax:
library(tidyverse)
list(x, y, z) %>% reduce(left_join, by = "i")
# A tibble: 3 x 4
# i j k l
# <chr> <int> <int> <int>
# 1 a 1 NA 9
# 2 b 2 4 NA
# 3 c 3 5 7
You can also perform other joins, such as a full_join
or inner_join
:
list(x, y, z) %>% reduce(full_join, by = "i")
# A tibble: 4 x 4
# i j k l
# <chr> <int> <int> <int>
# 1 a 1 NA 9
# 2 b 2 4 NA
# 3 c 3 5 7
# 4 d NA 6 8
list(x, y, z) %>% reduce(inner_join, by = "i")
# A tibble: 1 x 4
# i j k l
# <chr> <int> <int> <int>
# 1 c 3 5 7
2) dplyr::left_join()
with base R Reduce()
:
list(x,y,z) %>%
Reduce(function(dtf1,dtf2) left_join(dtf1,dtf2,by="i"), .)
# i j k l
# 1 a 1 NA 9
# 2 b 2 4 NA
# 3 c 3 5 7
3) Base R merge()
with base R Reduce()
:
And for comparison purposes, here is a base R version of the left join based on Charles's answer.
Reduce(function(dtf1, dtf2) merge(dtf1, dtf2, by = "i", all.x = TRUE),
list(x,y,z))
# i j k l
# 1 a 1 NA 9
# 2 b 2 4 NA
# 3 c 3 5 7
Another option to check your xpath is to use selenium IDE.
You need to look for "waiting to lock" in /data/anr/traces.txt file

I had the same issue. For me, depending on a user's permission level, some links, buttons and other elements will not show on the page. Part of my suite was testing that the elements that SHOULD be missing, are missing. I spent hours trying to figure this out. I finally found the perfect solution.
What this does, is tells the browser to look for any and all elements based specified. If it results in 0
, that means no elements based on the specification was found. Then i have the code execute an if statement to let me know it was not found.
This is in C#
, so translations would need to be done to Java
. But shouldnt be too hard.
public void verifyPermission(string link)
{
IList<IWebElement> adminPermissions = driver.FindElements(By.CssSelector(link));
if (adminPermissions.Count == 0)
{
Console.WriteLine("User's permission properly hidden");
}
}
There's also another path you can take depending on what you need for your test.
The following snippet is checking to see if a very specific element exists on the page. Depending on the element's existence I have the test execute an if else.
If the element exists and is displayed on the page, I have console.write
let me know and move on. If the element in question exists, I cannot execute the test I needed, which is the main reasoning behind needing to set this up.
If the element Does Not exists, and is not displayed on the page. I have the else in the if else execute the test.
IList<IWebElement> deviceNotFound = driver.FindElements(By.CssSelector("CSS LINK GOES HERE"));
//if the element specified above results in more than 0 elements and is displayed on page execute the following, otherwise execute whats in the else statement
if (deviceNotFound.Count > 0 && deviceNotFound[0].Displayed){
//script to execute if element is found
} else {
//Test script goes here.
}
I know I'm a little late on the response to the OP. Hopefully this helps someone!
You should be able to access your windows system under the /mnt
directory. For example inside of bash, use this to get to your pictures directory:
cd /mnt/c/Users/<ubuntu.username>/Pictures
Hope this helps!
yum update
helped me out. After I had
wget: symbol lookup error: wget: undefined symbol: psl_latest
I am stuck with same issue and find the easiest way to do this...
//Html
<button type="button" onclick="history.back()">Back</button>
OR
//Html
<button type="button" ng-click="goBack()">Back</button>
//JS
$scope.goBack = function() {
window.history.back();
};
(If you want it to be more testable, inject the $window service into your controller and use $window.history.back()).
If you have an issue in the httpd.conf or any files included by it there are a couple of ways to find out what the problem is
First look at your Windows Event Viewer
. Click on the Windows
link in the menu on the left, and then submenu Applications
.
Look for messages from Apache with the red error icon.
Secondly, open a command window, then CD into \wamp\bin\apache\apache2.x.y\bin, replace x,y with your actual version. Now you can run this command to get Apache(httpd) to vaidate the httpd.conf file.
httpd.exe -t
This should give errors with line numbers related to the http.conf file. It stops on the first error, so you will have to keep running it and fixing the error and then run it again until it gives the all OK message.
You can concatenate the CR and LF:
chr(13)||chr(10)
(on windows)
or just:
chr(10)
(otherwise)
dbms_output.put_line('Hi,'||chr(13)||chr(10) ||'good' || chr(13)||chr(10)|| 'morning' ||chr(13)||chr(10) || 'friends');
You did two mistakes . I think you misplace FROM and WHERE keywords.
SELECT DISTINCT Description, Date as treatmentDate
FROM doothey.Patient P, doothey.Account A, doothey.AccountLine AL, doothey.Item.I --Here you use "." operator to "I" alias
WHERE -- WHERE should be located here.
P.PatientID = A.PatientID
AND A.AccountNo = AL.AccountNo
AND AL.ItemNo = I.ItemNo
AND (p.FamilyName = 'Stange' AND p.GivenName = 'Jessie');

Here what I did in the similar case.
That sitatuation means that same entity has already been existed in the context.So following can help
First check from ChangeTracker if the entity is in the context
var trackedEntries=GetContext().ChangeTracker.Entries<YourEntityType>().ToList();
var isAlreadyTracked =
trackedEntries.Any(trackedItem => trackedItem.Entity.Id ==myEntityToSave.Id);
If it exists
if (isAlreadyTracked)
{
myEntityToSave= trackedEntries.First(trackedItem => trackedItem.Entity.Id == myEntityToSave.Id).Entity;
}
else
{
//Attach or Modify depending on your needs
}
If you are developing and testing in Firefox, there's a plug-in called "ReloadEvery" is available, which allows you to reload the page at the specified intervals.
Use dumpbin
command-line.
dumpbin /IMPORTS <path-to-file>
should provide the function imported into that DLL. dumpbin /EXPORTS <path-to-file>
should provide the functions it exports.Invoking of validation on form element could be handled by triggering change event on this element:
a) exemple: trigger change on separated element in form
$scope.formName.elementName.$$element.change();
b) exemple: trigger change event for each of form elements for example on ng-submit, ng-click, ng-blur ...
vm.triggerChangeForFormElements = function() {
// trigger change event for each of form elements
angular.forEach($scope.formName, function (element, name) {
if (!name.startsWith('$')) {
element.$$element.change();
}
});
};
c) and one more way for that
var handdleChange = function(form){
var formFields = angular.element(form)[0].$$controls;
angular.forEach(formFields, function(field){
field.$$element.change();
});
};
Hi please check the below link
https://www.postgresql.org/docs/current/xfunc-sql.html
EX:
CREATE FUNCTION sum_n_product_with_tab (x int)
RETURNS TABLE(sum int, product int) AS $$
SELECT $1 + tab.y, $1 * tab.y FROM tab;
$$ LANGUAGE SQL;
Debug.Print
outputs to the "Immediate" window.
Also, you can simply type ?
and then a statement directly into the immediate window (and then press Enter) and have the output appear right below, like this:
This can be very handy to quickly output the property of an object...
? myWidget.name
...to set the property of an object...
myWidget.name = "thingy"
...or to even execute a function or line of code, while in debugging mode:
Sheet1.MyFunction()
We can also set the vertical alignment with using this way
$style_cell = array(
'alignment' => array(
'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
'vertical' => PHPExcel_Style_Alignment::VERTICAL_CENTER,
)
);
with this cell set the vertically aligned into the middle.
What I did to solve the problem was:
git pull origin [branch]
git push origin [branch]
Also make sure that you are pointing to the right branch by running:
git remote set-url origin [url]
You should be able to run the command
git config --system core.longpaths true
or add it to one of your Git configuration files manually to turn this functionality on, once you are on a supported version of Git. It looks like maybe 1.9.0 and after.
If you are creating the SVG programmatically you can simplify it and do something like this:
<g>
<rect x={x} y={y} width={width} height={height} />
<text
x={x + width / 2}
y={y + height / 2}
dominant-baseline="middle"
text-anchor="middle"
>
{label}
</text>
</g>
The most important part about $ is that it has the lowest operator precedence.
If you type info you'll see this:
?> :info ($)
($) :: (a -> b) -> a -> b
-- Defined in ‘GHC.Base’
infixr 0 $
This tells us it is an infix operator with right-associativity that has the lowest possible precedence. Normal function application is left-associative and has highest precedence (10). So $ is something of the opposite.
So then we use it where normal function application or using () doesn't work.
So, for example, this works:
?> head . sort $ "example"
?> e
but this does not:
?> head . sort "example"
because . has lower precedence than sort and the type of (sort "example") is [Char]
?> :type (sort "example")
(sort "example") :: [Char]
But . expects two functions and there isn't a nice short way to do this because of the order of operations of sort and .
You have to add repositories
to your build file. For maven repositories you have to prefix repository name with maven{}
repositories {
maven { url "http://maven.springframework.org/release" }
maven { url "http://maven.restlet.org" }
mavenCentral()
}
I've been working kind of similar to this and I have some code that might help you. The live example is here and below, is the code I'm using for you to have it as reference.
create-page.php
<?php
// Session is started.
session_start();
// Name of the template file.
$template_file = 'couples-template.php';
// Root folder if working in subdirectory. Name is up to you ut must match with server's folder.
$base_path = '/couple/';
// Path to the directory where you store the "couples-template.php" file.
$template_path = '../template/';
// Path to the directory where php will store the auto-generated couple's pages.
$couples_path = '../couples/';
// Posted data.
$data['groom-name'] = str_replace(' ', '', $_POST['groom-name']);
$data['bride-name'] = str_replace(' ', '', $_POST['bride-name']);
// $data['groom-surname'] = $_POST['groom-surname'];
// $data['bride-surname'] = $_POST['bride-surname'];
$data['wedding-date'] = $_POST['wedding-date'];
$data['email'] = $_POST['email'];
$data['code'] = str_replace(array('/', '-', ' '), '', $_POST['wedding-date']).strtoupper(substr($data['groom-name'], 0, 1)).urlencode('&').strtoupper(substr($data['bride-name'], 0, 1));
// Data array (Should match with data above's order).
$placeholders = array('{groom-name}', '{bride-name}', '{wedding-date}', '{email}', '{code}');
// Get the couples-template.php as a string.
$template = file_get_contents($template_path.$template_file);
// Fills the template.
$new_file = str_replace($placeholders, $data, $template);
// Generates couple's URL and makes it frendly and lowercase.
$couples_url = str_replace(' ', '', strtolower($data['groom-name'].'-'.$data['bride-name'].'.php'));
// Save file into couples directory.
$fp = fopen($couples_path.$couples_url, 'w');
fwrite($fp, $new_file);
fclose($fp);
// Set the variables to pass them to success page.
$_SESSION['couples_url'] = $couples_url;
// If working in root directory.
$_SESSION['couples_path'] = str_replace('.', '', $couples_path);
// If working in a sub directory.
//$_SESSION['couples_path'] = substr_replace($base_path, '', -1).str_replace('.', '',$couples_path);

Try the following configuration:

log4j.category.debugLogger=TRACE, debugLog
log4j.additivity.debugLogger=false
log4j.category.reportsLogger=DEBUG, reportsLog
log4j.additivity.reportsLogger=false
Then configure the loggers in the Java code accordingly:
static final Logger debugLog = Logger.getLogger("debugLogger");
static final Logger resultLog = Logger.getLogger("reportsLogger");
Do you want output to go to stdout
? If not, change the first line of log4j.properties
to:
log4j.rootLogger=OFF
and get rid of the stdout
lines.
Well, I'm not sure that merge would be the way to go. Personally I would build a new data frame by creating an index of the dates and then constructing the columns using list comprehensions. Possibly not the most pythonic way, but it seems to work for me!
import pandas as pd
import numpy as np
df1 = pd.DataFrame(np.random.randn(5,3), index=pd.date_range('01/02/2014',periods=5,freq='D'), columns=['a','b','c'] )
df2 = pd.DataFrame(np.random.randn(8,3), index=pd.date_range('01/01/2014',periods=8,freq='D'), columns=['a','b','c'] )
# Create an index list from the set of dates in both data frames
Index = list(set(list(df1.index) + list(df2.index)))
Index.sort()
df3 = pd.DataFrame({'df1': [df1.loc[Date, 'c'] if Date in df1.index else np.nan for Date in Index],\
'df2': [df2.loc[Date, 'c'] if Date in df2.index else np.nan for Date in Index],},\
index = Index)
df3
Here's a different implementation of Jenny Lang's answer that works for Rails 5.
First create the migration file:
bundle exec be rails g migration DropEpisodes
Then populate the migration file as follows:
class DropEpisodes < ActiveRecord::Migration[5.1]
def change
drop_table :episodes
end
end
Running rails db:migrate
will drop the table. If you run rails db:rollback
, Rails will throw a ActiveRecord::IrreversibleMigration
error.
Fibonacci sequence is: 1, 1, 2, 3, 5, 8, ...
.
That is f(1) = 1
, f(2) = 1
, f(3) = 2
, ...
, f(n) = f(n-1) + f(n-2)
.
My favorite implementation (simplest and yet achieves a light speed in compare to other implementations) is this:
def fibonacci(n):
a, b = 0, 1
for _ in range(1, n):
a, b = b, a + b
return b
Test
>>> [fibonacci(i) for i in range(1, 10)]
[1, 1, 2, 3, 5, 8, 13, 21, 34]
Timing
>>> %%time
>>> fibonacci(100**3)
CPU times: user 9.65 s, sys: 9.44 ms, total: 9.66 s
Wall time: 9.66 s
Edit: an example visualization for this implementations.
You can't use string.replace...as one string is assigned you cannot manipulate. For that, we use string builder. Here is my example. In the HTML page I add [Name] which is replaced by Name. Make sure [Name] is unique or you can give any unique name:
string Name = txtname.Text;
string contents = File.ReadAllText(Server.MapPath("~/Admin/invoice.html"));
StringBuilder builder = new StringBuilder(contents);
builder.Replace("[Name]", Name);
StringReader sr = new StringReader(builder.ToString());

I have found one another simple way to store the data into the database
models.py
class LinkModel(models.Model):
link = models.CharField(max_length=500)
shortLink = models.CharField(max_length=30,unique=True)
In database I have only 2 variables
views.py
class HomeView(TemplateView):
def post(self,request, *args, **kwargs):
form = LinkForm(request.POST)
if form.is_valid():
text = form.cleaned_data['link'] # text for link
dbobj = LinkModel()
dbobj.link = text
self.no = self.gen.generateShortLink() # no for shortLink
dbobj.shortLink = str(self.no)
dbobj.save() # Saving from views.py
In this I have created the instance of model in views.py only and putting/saving data into 2 variables from views only.
Try this:
Write-Host ($obj | Format-Table | Out-String)
or
Write-Host ($obj | Format-List | Out-String)
Try this in the console:
JSON.parse(undefined)
Here is what you will get:
Uncaught SyntaxError: Unexpected token u in JSON at position 0
at JSON.parse (<anonymous>)
at <anonymous>:1:6
In other words, your app is attempting to parse undefined
, which is not valid JSON.
There are two common causes for this. The first is that you may be referencing a non-existent property (or even a non-existent variable if not in strict mode).
window.foobar = '{"some":"data"}';
JSON.parse(window.foobarn) // oops, misspelled!
The second common cause is failure to receive the JSON in the first place, which could be caused by client side scripts that ignore errors and send a request when they shouldn't.
Make sure both your server-side and client-side scripts are running in strict mode and lint them using ESLint. This will give you pretty good confidence that there are no typos.
Thanks to Novocaine88's answer to use a try catch loop I have successfully received an error message when I caused one.
<?php
$dbhost = "localhost";
$dbname = "pdo";
$dbusername = "root";
$dbpassword = "845625";
$link = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbusername, $dbpassword);
$link->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
try {
$statement = $link->prepare("INERT INTO testtable(name, lastname, age)
VALUES(?,?,?)");
$statement->execute(array("Bob","Desaunois",18));
} catch(PDOException $e) {
echo $e->getMessage();
}
?>
In the following code instead of INSERT INTO it says INERT.
this is the error I got.
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'INERT INTO testtable(name, lastname, age) VALUES('Bob','Desaunoi' at line 1
When I "fix" the issue, it works as it should. Thanks alot everyone!
If I remember correctly, you'll need to set the netbeans_jdkhome
property in your netbeans config file. Should be in your etc/netbeans.conf
file.
Building off of Mamboking's answer:

m_prog = new ProcessOrdersWorker(m_orderSvc, m_opportunitySvc, m_myprojectOrgSvc);

Addressing your request to verify whether the argument contains a certain value, I could assume you mean that the argument is a String and you want to test whether the String argument contains a substring. For this you could do:
ArgumentCaptor<String> savedCaptor = ArgumentCaptor.forClass(String.class);
verify(mock_contractsDao).save(savedCaptor.capture());
assertTrue(savedCaptor.getValue().contains("substring I want to find");
If that assumption was wrong, and the argument to save()
is a collection of some kind, it would be only slightly different:
ArgumentCaptor<Collection<MyType>> savedCaptor = ArgumentCaptor.forClass(Collection.class);
verify(mock_contractsDao).save(savedCaptor.capture());
assertTrue(savedCaptor.getValue().contains(someMyTypeElementToFindInCollection);
You might also check into ArgumentMatchers, if you know how to use Hamcrest matchers.
That won't work if the string contains more than one match... try this:
echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo " $0) }'
or better (if the echo
isn't a placeholder for something else):
echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'
In your case you want to make a copy of the value before changing it:
echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'
(in the following code, you should substitute 'UTC'

turns our current time (of type timestamp with time zone) into the timezonless equivalent in UTC

You could try Firebug Lite
It's a pure JavaScript-implementation of Firebug that runs directly in any browser (at least in all major ones: IE6+, Firefox, Opera, Safari and Chrome)
You'll still need the VM to actually run IE, but at least you'll get a quicker testing cycle.

rapidjson is a C++ JSON parser/generator designed to be fast and small memory footprint.
There is a performance comparison with YAJL and JsonCPP.
Update:
I created an open source project Native JSON benchmark, which evaluates 29 (and increasing) C/C++ JSON libraries, in terms of conformance and performance. This should be an useful reference.
First of all check error log in the path that your webserver indicates. Then maybe the browser is showing friendly error messages, so disable it.

File manipulation isn't normally done by Bash, but by programs invoked by Bash, e.g.:
perl -pi -e 's/abc/XYZ/g' /tmp/file.txt
The -i
flag tells it to do an in-place replacement.
See man perlrun
for more details, including how to take a backup of the original file.
Just add to the CommandArgument
parameter and read it out on the Click
handler:
<asp:LinkButton ID="ENameLinkBtn" runat="server"
style="font-weight: 700; font-size: 8pt;" CommandArgument="YourValueHere"
OnClick="ENameLinkBtn_Click" >
Then in your click event:
protected void ENameLinkBtn_Click(object sender, EventArgs e)
{
LinkButton btn = (LinkButton)(sender);
string yourValue = btn.CommandArgument;
// do what you need here
}
Also you can set the CommandArgument
argument when binding if you are using the LinkButton
in any bindable controls by doing:
CommandArgument='<%# Eval("SomeFieldYouNeedArguementFrom") %>'

The other answers are not working for me - they may be outdated. This is what I used as my solution for auto setting an attribute:
/**
* The "booting" method of the model.
*
* @return void
*/
protected static function boot()
{
parent::boot();
// auto-sets values on creation
static::creating(function ($query) {
$query->is_voicemail = $query->is_voicemail ?? true;
});
}
Because $xml->xpath
always return an array, and strlen
expects a string.
You can take advantage of Groovy features like with(), improvements to URLConnection, and simplified getters/setters:
GET:
String getResult = new URL('http://mytestsite/bloop').text
POST:
String postResult
((HttpURLConnection)new URL('http://mytestsite/bloop').openConnection()).with({
requestMethod = 'POST'
doOutput = true
setRequestProperty('Content-Type', '...') // Set your content type.
outputStream.withPrintWriter({printWriter ->
printWriter.write('...') // Your post data. Could also use withWriter() if you don't want to write a String.
})
// Can check 'responseCode' here if you like.
postResult = inputStream.text // Using 'inputStream.text' because 'content' will throw an exception when empty.
})
Note, the POST will start when you try to read a value from the HttpURLConnection, such as responseCode
, inputStream.text
, or getHeaderField('...')
.

The rules for turning on the carry flag in binary/integer math are two:
The carry flag is set if the addition of two numbers causes a carry out of the most significant (leftmost) bits added. 1111 + 0001 = 0000 (carry flag is turned on)
The carry (borrow) flag is also set if the subtraction of two numbers requires a borrow into the most significant (leftmost) bits subtracted. 0000 - 0001 = 1111 (carry flag is turned on) Otherwise, the carry flag is turned off (zero).
In unsigned arithmetic, watch the carry flag to detect errors.
In signed arithmetic, the carry flag tells you nothing interesting.
The rules for turning on the overflow flag in binary/integer math are two:
If the sum of two numbers with the sign bits off yields a result number with the sign bit on, the "overflow" flag is turned on. 0100 + 0100 = 1000 (overflow flag is turned on)
If the sum of two numbers with the sign bits on yields a result number with the sign bit off, the "overflow" flag is turned on. 1000 + 1000 = 0000 (overflow flag is turned on)
Otherwise the "overflow" flag is turned off
Note that you only need to look at the sign bits (leftmost) of the three numbers to decide if the overflow flag is turned on or off.
If you are doing two's complement (signed) arithmetic, overflow flag on means the answer is wrong - you added two positive numbers and got a negative, or you added two negative numbers and got a positive.
If you are doing unsigned arithmetic, the overflow flag means nothing and should be ignored.
For more clarification please refer: http://teaching.idallen.com/dat2343/10f/notes/040_overflow.txt
If you just want to be able to copy text from the control but not be able to edit it you might want to use a TextView instead and set text is selectable.
code:
myTextView.setTextIsSelectable(true);
myTextView.setFocusable(true);
myTextView.setFocusableInTouchMode(true);
// myTextView.setSelectAllOnFocus(true);
xml:
<TextView
android:textIsSelectable="true"
android:focusable="true"
android:focusableInTouchMode="true"
...
/>
<!--android:selectAllOnFocus="true"-->
The documentation of setTextIsSelectable says:
When you call this method to set the value of textIsSelectable, it sets the flags focusable, focusableInTouchMode, clickable, and longClickable to the same value...
However I had to explicitly set focusable and focusableInTouchMode to true to make it work with touch input.
Apply classes to your TDs, apply the appropriate widths (remember to leave one of them without a width so it assumes the remainder of the width), then apply the appropriate styles. Copy and paste the code below into an editor and view in a browser to see it function.

Late answer, but many views. As APIs < 11 ain't dead yet, for those interested here is a trick.
Let your container have the desired color (may be transparent). Then give your buttons a selector with default transparent color, and some color when pressed. That way you'll have a transparent button, but will change color when pressed (like holo's). You can also add some animation (like holo's). The selector should be something like this:
res/drawable/selector_transparent_button.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"
android:exitFadeDuration="@android:integer/config_shortAnimTime">
<item android:state_pressed="true"
android:drawable="@color/blue" />
<item android:drawable="@color/transparent" />
</selector>
And the button should have android:background="@drawable/selector_transparent_button"
PS: let you container have the dividers (android:divider='@android:drawable/...
for API < 11)
PS [Newbies]: you should define those colors in values/colors.xml

CheckUpDown has a nice explanation of the 504 error:
A server (not necessarily a Web server) is acting as a gateway or proxy to fulfil the request by the client (e.g. your Web browser or our CheckUpDown robot) to access the requested URL. This server did not receive a timely response from an upstream server it accessed to deal with your HTTP request.
This usually means that the upstream server is down (no response to the gateway/proxy), rather than that the upstream server and the gateway/proxy do not agree on the protocol for exchanging data.
This problem is entirely due to slow IP communication between back-end computers, possibly including the Web server. Only the people who set up the network at the site which hosts the Web server can fix this problem.

The TextView resource id it needs is for a TextView layout file, so it won't be in the same activity.
You can create it by going to File > New > XML > XML Layout File, and enter the widget type, which is 'TextView' in the root tag field.

The answers only cover DOM / SAX and a copy paste implementation of a JAXB example.
However, one big area of when you are using XML is missing. In many projects / programs there is a need to store / retrieve some basic data structures. Your program has already a classes for your nice and shiny business objects / data structures, you just want a comfortable way to convert this data to a XML structure so you can do more magic on it (store, load, send, manipulate with XSLT).
This is where XStream shines. You simply annotate the classes holding your data, or if you do not want to change those classes, you configure a XStream instance for marshalling (objects -> xml) or unmarshalling (xml -> objects).
Internally XStream uses reflection, the readObject and readResolve methods of standard Java object serialization.
You get a good and speedy tutorial here:
To give a short overview of how it works, I also provide some sample code which marshalls and unmarshalls a data structure.
The marshalling / unmarshalling happens all in the main
method, the rest is just code to generate some test objects and populate some data to them.
It is super simple to configure the xStream
instance and marshalling / unmarshalling is done with one line of code each.
import java.math.BigDecimal;
import java.util.ArrayList;
import java.util.List;
import com.thoughtworks.xstream.XStream;
public class XStreamIsGreat {
public static void main(String[] args) {
XStream xStream = new XStream();
xStream.alias("good", Good.class);
xStream.alias("pRoDuCeR", Producer.class);
xStream.alias("customer", Customer.class);
Producer a = new Producer("Apple");
Producer s = new Producer("Samsung");
Customer c = new Customer("Someone").add(new Good("S4", 10, new BigDecimal(600), s))
.add(new Good("S4 mini", 5, new BigDecimal(450), s)).add(new Good("I5S", 3, new BigDecimal(875), a));
String xml = xStream.toXML(c); // objects -> xml
System.out.println("Marshalled:\n" + xml);
Customer unmarshalledCustomer = (Customer)xStream.fromXML(xml); // xml -> objects
}
static class Good {
Producer producer;
String name;
int quantity;
BigDecimal price;
Good(String name, int quantity, BigDecimal price, Producer p) {
this.producer = p;
this.name = name;
this.quantity = quantity;
this.price = price;
}
}
static class Producer {
String name;
public Producer(String name) {
this.name = name;
}
}
static class Customer {
String name;
public Customer(String name) {
this.name = name;
}
List<Good> stock = new ArrayList<Good>();
Customer add(Good g) {
stock.add(g);
return this;
}
}
}
Cloudfront will cache a file/object until the cache expiry. By default it is 24 hrs. If you have changed this to a large value, then it takes longer.
If you anytime needs to force clear the cache, use the invalidation. It is charged separately.
Another option is to change the URL (object key), so it fetches the new object always.
This works in May 2020 using PDFminer six in Python3.
$ pip install pdfminer.six
from pdfminer.high_level import extract_text
text = extract_text('report.pdf')
Or alternatively:
with open('report.pdf','rb') as f:
text = extract_text(f)
If the PDF is already in memory, for example if retrieved from the web with the requests library, it can be converted to a stream using the io
library:
import io
response = requests.get(url)
text = extract_text(io.BytesIO(response.content))
PDFminer.six works more reliably than PyPDF2 (which fails with certain types of PDFs), in particular PDF version 1.7
However, text extraction with PDFminer.six is significantly slower than PyPDF2 by a factor of 6.
I timed text extraction with timeit
on a 15" MBP (2018), timing only the extraction function (no file opening etc.) with a 10 page PDF and got the following results:
PDFminer.six: 2.88 sec
PyPDF2: 0.45 sec
pdfminer.six also has a huge footprint, requiring pycryptodome which needs GCC and other things installed pushing a minimal install docker image on Alpine Linux from 80 MB to 350 MB. PyPDF2 has no noticeable storage impact.

Yum doesn't have it's own package type. Yum operates and helps manage RPMs. So, you can use yum to list the available RPMs and then run the rpm -qlp command to see the contents of that package.

A predicate is a function that returns a true/false (i.e. boolean) value, as opposed to a proposition which is a true/false (i.e. boolean) value. In Java, one cannot have standalone functions, and so one creates a predicate by creating an interface for an object that represents a predicate and then one provides a class that implements that interface. An example of an interface for a predicate might be:
public interface Predicate<ARGTYPE>
{
public boolean evaluate(ARGTYPE arg);
}
And then you might have an implementation such as:
public class Tautology<E> implements Predicate<E>
{
public boolean evaluate(E arg){
return true;
}
}
To get a better conceptual understanding, you might want to read about first-order logic.
Edit
There is a standard Predicate interface (java.util.function.Predicate) defined in the Java API as of Java 8. Prior to Java 8, you may find it convenient to reuse the com.google.common.base.Predicate interface from Guava.
Also, note that as of Java 8, it is much simpler to write predicates by using lambdas. For example, in Java 8 and higher, one can pass p -> true
to a function instead of defining a named Tautology subclass like the above.
Update: Python 3.6 implements PEP 528: Change Windows console encoding to UTF-8: the default console on Windows will now accept all Unicode characters. Internally, it uses the same Unicode API as the win-unicode-console
package mentioned below. print(unicode_string)
should just work now.
I get a
UnicodeEncodeError: 'charmap' codec can't encode character...
error.
The error means that Unicode characters that you are trying to print can't be represented using the current (chcp
) console character encoding. The codepage is often 8-bit encoding such as cp437
that can represent only ~0x100 characters from ~1M Unicode characters:
>>> u"\N{EURO SIGN}".encode('cp437') Traceback (most recent call last): ... UnicodeEncodeError: 'charmap' codec can't encode character '\u20ac' in position 0: character maps to
I assume this is because the Windows console does not accept Unicode-only characters. What's the best way around this?
Windows console does accept Unicode characters and it can even display them (BMP only) if the corresponding font is configured. WriteConsoleW()
API should be used as suggested in @Daira Hopwood's answer. It can be called transparently i.e., you don't need to and should not modify your scripts if you use win-unicode-console
package:
T:\> py -mpip install win-unicode-console
T:\> py -mrun your_script.py
See What's the deal with Python 3.4, Unicode, different languages and Windows?
Is there any way I can make Python automatically print a
?
instead of failing in this situation?
If it is enough to replace all unencodable characters with ?
in your case then you could set PYTHONIOENCODING
envvar:
T:\> set PYTHONIOENCODING=:replace
T:\> python3 -c "print(u'[\N{EURO SIGN}]')"
[?]
In Python 3.6+, the encoding specified by PYTHONIOENCODING
envvar is ignored for interactive console buffers unless PYTHONLEGACYWINDOWSIOENCODING
envvar is set to a non-empty string.
Beware the leading 00 that can appear in the modulus when using:
openssl rsa -pubin -inform PEM -text -noout < public.key
The example modulus contains 257 bytes rather than 256 bytes because of that 00, which is included because the 9 in 98 looks like a negative signed number.

{
Write-Host "No Breakout for you!"

Make sure to learn from the padding oracle asp.net vulnerability that just happened (you applied the patch, right? ...) and use protected sections to encrypt the machine key and any other sensitive configuration.
An alternative option is to set it in the machine level web.config, so its not even in the web site folder.
To generate it do it just like the linked article in David's answer.
In my case, the above alone didn't work. I had installed and uninstalled several versions of nodejs to fix this error: npm in windows Error: EISDIR, read at Error (native) that I kept getting on any npm command I tried to run, including getting the npm version with: npm -v
.
So the npm directory was deleted in the nodejs folder and the latest npm version was copied over from the npm dist: and then everything started working.
If you have merged cells,
Sub OneCell()
Sheets("Sheet2").range("B1:B3").value = Sheets("Sheet1").range("A1:A3").value
End Sub
that doesn't copy cells as they are, where previous code does copy exactly as they look like (merged).
@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
#myElement {
/* Enter your style code */
}
}
Explanation: It is a Microsoft-specific media query. Using -ms-high-contrast property specific to Microsoft IE, it will only be parsed in Internet Explorer 10 or greater. I have used both the valid values of the media query, so it will be parsed by IE only, whether the user has high contrast enabled or not.
It sounds like you're trying to SELECT
a column that doesn't exist.
Perhaps you're trying to ORDER BY
a column that doesn't exist?
Any typos in your SQL statement?
I think it is telling you exactly what is wrong. You cannot compare an integer with a varchar. PostgreSQL is strict and does not do any magic typecasting for you. I'm guessing SQLServer does typecasting automagically (which is a bad thing).
If you want to compare these two different beasts, you will have to cast one to the other using the casting syntax ::
.
Something along these lines:
create view view1
as
select table1.col1,table2.col1,table3.col3
from table1
inner join
table2
inner join
table3
on
table1.col4::varchar = table2.col5
/* Here col4 of table1 is of "integer" type and col5 of table2 is of type "varchar" */
/* ERROR: operator does not exist: integer = character varying */
....;
Notice the varchar
typecasting on the table1.col4.
Also note that typecasting might possibly render your index on that column unusable and has a performance penalty, which is pretty bad. An even better solution would be to see if you can permanently change one of the two column types to match the other one. Literately change your database design.
Or you could create a index on the casted values by using a custom, immutable function which casts the values on the column. But this too may prove suboptimal (but better than live casting).
Use Directly like this
.bg-div{
background: url(../img/beach.jpg) no-repeat fixed 100% 100%;
}
or call CSS separately like
.bg-div{
background-image: url(../img/beach.jpg);
-moz-background-size: cover;
-webkit-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
If you dont want to hard-code the cell addresses you can use the ROW()
function.
eg: =AVERAGE(INDIRECT("A" & ROW()), INDIRECT("C" & ROW()))
Its probably not the best way to do it though! Using Auto-Fill and static columns like @JaiGovindani suggests would be much better.
Null termination is a bad design pattern best left in the history books. There's still plenty of inertia behind c-strings, so it can't be avoided there. But there's no reason to use it in the OP's example.
Don't use any terminator, and use sizeof(array) / sizeof(array[0]) to get the number of elements.
The solution is way easier.

Here's a method that worked for me. When you type into the field, it puts that text into the hidden span, then gets its new width and applies it to the input field. It grows and shrinks with your input, with a safeguard against the input virtually disappearing when you erase all input. Tested in Chrome.

Does deleting the AppID do anything to disable versions of an Enterprise distributed app "in the wild" ??
If not, is there any way to kill off an Enterprise app before it's expiry?

I had some post content I had to cipher throughout to get the Youtube ID out of. It happened to be in the form of the <iframe>
embed code Youtube provides.
<iframe src="http://www.youtube.com/embed/Zpk8pMz_Kgw?rel=0" frameborder="0" width="620" height="360"></iframe>
The following pattern I got from @rob above. The snippet does a foreach
loop once the matches are found, and for a added bonus I linked it to the preview image found on Youtube. It could potentially match more types of Youtube embed types and urls:
$pattern = '#(?<=(?:v|i)=)[a-zA-Z0-9-]+(?=&)|(?<=(?:v|i)\/)[^&\n]+|(?<=embed\/)[^"&\n]+|(?<=??(?:v|i)=)[^&\n]+|(?<=youtu.be\/)[^&\n]+#';
preg_match_all($pattern, $post_content, $matches);
foreach ($matches as $match) {
$img = "<img src='http://img.youtube.com/vi/".str_replace('?rel=0','', $match[0])."/0.jpg' />";
break;
}

Let's take a look at the list of Docker's technical features, and check which ones are provided by LXC and which ones aren't.
1) Filesystem isolation: each process container runs in a completely separate root filesystem.
Provided with plain LXC.
2) Resource isolation: system resources like cpu and memory can be allocated differently to each process container, using cgroups.
Provided with plain LXC.
3) Network isolation: each process container runs in its own network namespace, with a virtual interface and IP address of its own.
Provided with plain LXC.
4) Copy-on-write: root filesystems are created using copy-on-write, which makes deployment extremely fast, memory-cheap and disk-cheap.
This is provided by AUFS, a union filesystem that Docker depends on. You could set up AUFS yourself manually with LXC, but Docker uses it as a standard.
5) Logging: the standard streams (stdout/stderr/stdin) of each process container is collected and logged for real-time or batch retrieval.
Docker provides this.
6) Change management: changes to a container's filesystem can be committed into a new image and re-used to create more containers. No templating or manual configuration required.
"Templating or manual configuration" is a reference to LXC, where you would need to learn about both of these things. Docker allows you to treat containers in the way that you're used to treating virtual machines, without learning about LXC configuration.
7) Interactive shell: docker can allocate a pseudo-tty and attach to the standard input of any container, for example to run a throwaway interactive shell.
LXC already provides this.
I only just started learning about LXC and Docker, so I'd welcome any corrections or better answers.
var item = "one,two,three";
var lastItem = item.split(",").pop();
console.log(lastItem); // three
But still, the memory address for each letter in this address is different.
Memory address is different but as its array of characters they are sequential. When you pass address of first element and use %s
, printf
will print all characters starting from given address until it finds '\0'
.
I used this function to strip newline or other characters in data to parse JSON data:
function normalize_str($str) {
$invalid = array(
'Š'=>'S', 'š'=>'s', 'Ð'=>'Dj', 'd'=>'dj', 'Ž'=>'Z', 'ž'=>'z',
'C'=>'C', 'c'=>'c', 'C'=>'C', 'c'=>'c', 'À'=>'A', 'Á'=>'A', 'Â'=>'A', 'Ã'=>'A',

'´' => "'", '"' => '\"', '"' => "\"", '´' => "'",
"’" => "'",
"{" => "",
"~" => "", "–" => "-", "'" => "'", " " => " ");
$str = str_replace(array_keys($invalid), array_values($invalid), $str);
$remove = array("\n", "\r\n", "\r");
$str = str_replace($remove, "\\n", trim($str));
//$str = htmlentities($str, ENT_QUOTES);
return htmlspecialchars($str);
}
echo normalize_str($lst['address']);
I had this same problem and created a jQuery plugin to solve it for our site.
https://github.com/shaunbowe/jquery.visibilityChanged
Here is how you would use it based on your example:
$('#contentDiv').visibilityChanged(function(element, visible) {
alert("do something");
});
I believe this is what you are looking for:
Indexers (C# Programming Guide)
class SampleCollection<T>
{
private T[] arr = new T[100];
public T this[int i]
{
get => arr[i];
set => arr[i] = value;
}
}
// This class shows how client code uses the indexer
class Program
{
static void Main(string[] args)
{
SampleCollection<string> stringCollection =
new SampleCollection<string>();
stringCollection[0] = "Hello, World";
System.Console.WriteLine(stringCollection[0]);
}
}
On Windows Vista/7, with UAC, administrator accounts run programs in unprivileged mode by default.
Programs must prompt for administrator access before they run as administrator, with the ever-so-familiar UAC dialog. Since Python scripts aren't directly executable, there's no "Run as Administrator" context menu option.
It's possible to use ctypes.windll.shell32.IsUserAnAdmin()
to detect whether the script has admin access, and ShellExecuteEx
with the 'runas' verb on python.exe, with sys.argv[0] as a parameter to prompt the UAC dialog if needed.
You can set the variable 'fileencodings' in your .vimrc.
This is a list of character encodings considered when starting to edit an existing file. When a file is read, Vim tries to use the first mentioned character encoding. If an error is detected, the next one in the list is tried. When an encoding is found that works, 'fileencoding' is set to it. If all fail, 'fileencoding' is set to an empty string, which means the value of 'encoding' is used.
See :help filencodings
If you often work with e.g. cp1252, you can add it there:
set fileencodings=ucs-bom,utf-8,cp1252,default,latin9

MEMORY USAGE key
command gives you the number of bytes that a key and its value require to be stored in RAM.
The reported usage is the total of memory allocations for data and administrative overheads that a key its value require (source redis documentation)
I attempted
pod install --repo-update
and all of these still did not fix the problem.
Same issue with mine.
New to Flutter. I'm using VS build-in terminal to do flutter run
, to run the app in iPhone. It gives me error Error when reading 'lib/student_model.dart': No such file...
, which is an old code version in my code. I have changed it to lib/model/student_model.dart
.
And I search this line 'lib/student_model.dart'in the project, it appears file
kernel_snapshot.d` containing it. So, it build the project with old code version.
For me, Flutter clean
is not working. Restart VS fix the issue, not sure the problem is due to Flutter or VS?
And I'm wondering if there is some command to just build flutter project without run?
I just tested a couple paths using Excel 2013 on on Windows 7. I found the overall pathname limit to be 213 and the basename length to be 186. At least the error dialog for exceeding basename length is clear:
And trying to move a not-too-long basename to a too-long-pathname is also very clear:
The pathname error is deceptive, though. Quite unhelpful:
This is a lazy Microsoft restriction. There's no good reason for these arbitrary length limits, but in the end, it’s a real bug in the error dialog.

I read the other questions on Stack but I was still a little confused on communicating across classes. Here is how I approached it:
I use a list to hold all my threads in the __init__
method of my wxFrame class: self.threads = []
As recommended in How to stop a looping thread in Python? I use a signal in my thread class which is set to True
when initializing the threading class.
class PingAssets(threading.Thread):
def __init__(self, threadNum, asset, window):
threading.Thread.__init__(self)
self.threadNum = threadNum
self.window = window
self.asset = asset
self.signal = True
def run(self):
while self.signal:
do_stuff()
sleep()
and I can stop these threads by iterating over my threads:
def OnStop(self, e):
for t in self.threads:
t.signal = False
You can make a symbolic link of your module to the standard path, so depmod will see it and you'll be able load it as any other module.
sudo ln -s /path/to/module.ko /lib/modules/`uname -r`
sudo depmod -a
sudo modprobe module
If you add the module name to /etc/modules it will be loaded any time you boot.
Anyway I think that the proper configuration is to copy the module to the standard paths.
I was reading this thread and would like to add information even though it is surely no longer timely for the OP.
BiggerDon above points out the difficulty of rote replacing "North" with "N". A similar problem exists with "Avenue" to "Ave" (e.g. "Avenue of the Americas" becomes "Ave of the Americas": still understandable, but probably not what the OP wants.
The replace() function is entirely context-free, but addresses are not. A complete solution needs to have additional logic to interpret the context correctly, and then apply replace() as needed.
Databases commonly contain addresses, and so I wanted to point out that the generalized version of the OP's problem as applied to addresses within the United States has been addressed (humor!) by the Coding Accuracy Support System (CASS). CASS is a database tool that accepts a U.S. address and completes or corrects it to meet a standard set by the U.S. Postal Service. The Wikipedia entry https://en.wikipedia.org/wiki/Postal_address_verification has the basics, and more information is available at the Post Office: https://ribbs.usps.gov/index.cfm?page=address_info_systems

Bam ! |Done¬
To answer the second part of this question, the two packages shown in pip list
but not pip freeze
are setuptools
(which is easy_install) and pip
itself.
It looks like pip freeze
just doesn't list packages that pip itself depends on. You may use the --all
flag to show also those packages.
From the documentation:
--all
Do not skip these packages in the output: pip, setuptools, distribute, wheel

I get the same error. the solution is to put your script code before the end of body, not in the head section.
Just go to the \eclipse-java-helios-SR2-win32\eclipse\configuration.settings directory and change or remove org.eclipse.ui.ide.prefs file.
Is it possible to do it this way, as opposed to using something like Raphael or jQuery SVG?
Definitely.
If it is possible, what's the technique?
This annotated code snippet works:
<!DOCTYPE html>
<html>
<head>
<title>SVG Illustrator Test</title>
</head>
<body>
<object data="alpha.svg" type="image/svg+xml"
id="alphasvg" width="100%" height="100%"></object>
<script>
var a = document.getElementById("alphasvg");
// It's important to add an load event listener to the object,
// as it will load the svg doc asynchronously
a.addEventListener("load",function(){
// get the inner DOM of alpha.svg
var svgDoc = a.contentDocument;
// get the inner element by id
var delta = svgDoc.getElementById("delta");
// add behaviour
delta.addEventListener("mousedown",function(){
alert('hello world!')
}, false);
}, false);
</script>
</body>
</html>
Note that a limitation of this technique is that it is restricted by the same-origin policy, so alpha.svg
must be hosted on the same domain as the .html
file, otherwise the inner DOM of the object will be inaccessible.
Important thing to run this HTML, you need host HTML file to web server like IIS, Tomcat
If you have a remote configured and you have / don't care about losing some unpushed code, you can do :
git fetch && git reset --hard
You can try a list comp
>>> exampleSet = [{'type':'type1'},{'type':'type2'},{'type':'type2'}, {'type':'type3'}]
>>> keyValList = ['type2','type3']
>>> expectedResult = [d for d in exampleSet if d['type'] in keyValList]
>>> expectedResult
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]
Another way is by using filter
>>> list(filter(lambda d: d['type'] in keyValList, exampleSet))
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]
I started out with Johannes Farhenkrug's answer here and it worked great for me. I needed to mock the requests library because my goal is to isolate my application and not test any 3rd party resources.
Then I read up some more about python's Mock library and I realized that I can replace the MockResponse class, which you might call a 'Test Double' or a 'Fake', with a python Mock class.
The advantage of doing so is access to things like assert_called_with
, call_args
and so on. No extra libraries are needed. Additional benefits such as 'readability' or 'its more pythonic' are subjective, so they may or may not play a role for you.
Here is my version, updated with using python's Mock instead of a test double:
import json
import requests
from unittest import mock
# defube stubs
AUTH_TOKEN = '{"prop": "value"}'
LIST_OF_WIDGETS = '{"widgets": ["widget1", "widget2"]}'
PURCHASED_WIDGETS = '{"widgets": ["purchased_widget"]}'
# exception class when an unknown URL is mocked
class MockNotSupported(Exception):
pass
# factory method that cranks out the Mocks
def mock_requests_factory(response_stub: str, status_code: int = 200):
return mock.Mock(**{
'json.return_value': json.loads(response_stub),
'text.return_value': response_stub,
'status_code': status_code,
'ok': status_code == 200
})
# side effect mock function
def mock_requests_post(*args, **kwargs):
if args[0].endswith('/api/v1/get_auth_token'):
return mock_requests_factory(AUTH_TOKEN)
elif args[0].endswith('/api/v1/get_widgets'):
return mock_requests_factory(LIST_OF_WIDGETS)
elif args[0].endswith('/api/v1/purchased_widgets'):
return mock_requests_factory(PURCHASED_WIDGETS)
raise MockNotSupported
# patch requests.post and run tests
with mock.patch('requests.post') as requests_post_mock:
requests_post_mock.side_effect = mock_requests_post
response = requests.post('https://myserver/api/v1/get_widgets')
assert response.ok is True
assert response.status_code == 200
assert 'widgets' in response.json()
# now I can also do this
requests_post_mock.assert_called_with('https://myserver/api/v1/get_widgets')

I think this may be the easiest way to do it.
https://coderwall.com/p/ebqhca/javascript-sort-by-two-fields
It's really simple and I tried it with 3 different key value pairs and it worked great.
Here is a simple example, look at the link for more details
testSort(data) {
return data.sort(
a['nameOne'] > b['nameOne'] ? 1
: b['nameOne'] > a['nameOne'] ? -1 : 0 ||
a['date'] > b['date'] ||
a['number'] - b['number']
);
}
I think a quick way to change the options of a widget is using the configure
method.
In your case, it would look like this:
self.x.configure(state=NORMAL)
It's not generally correct that you can "remove an item from a database" with both methods. To be precise it is like so:
ObjectContext.DeleteObject(entity)
marks the entity as Deleted
in the context. (It's EntityState
is Deleted
after that.) If you call SaveChanges
afterwards EF sends a SQL DELETE
statement to the database. If no referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.
EntityCollection.Remove(childEntity)
marks the relationship between parent and childEntity
as Deleted
. If the childEntity
itself is deleted from the database and what exactly happens when you call SaveChanges
depends on the kind of relationship between the two:
If the relationship is optional, i.e. the foreign key that refers from the child to the parent in the database allows NULL
values, this foreign will be set to null and if you call SaveChanges
this NULL
value for the childEntity
will be written to the database (i.e. the relationship between the two is removed). This happens with a SQL UPDATE
statement. No DELETE
statement occurs.
If the relationship is required (the FK doesn't allow NULL
values) and the relationship is not identifying (which means that the foreign key is not part of the child's (composite) primary key) you have to either add the child to another parent or you have to explicitly delete the child (with DeleteObject
then). If you don't do any of these a referential constraint is violated and EF will throw an exception when you call SaveChanges
- the infamous "The relationship could not be changed because one or more of the foreign-key properties is non-nullable" exception or similar.
If the relationship is identifying (it's necessarily required then because any part of the primary key cannot be NULL
) EF will mark the childEntity
as Deleted
as well. If you call SaveChanges
a SQL DELETE
statement will be sent to the database. If no other referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.
I am actually a bit confused about the Remarks section on the MSDN page you have linked because it says: "If the relationship has a referential integrity constraint, calling the Remove method on a dependent object marks both the relationship and the dependent object for deletion.". This seems unprecise or even wrong to me because all three cases above have a "referential integrity constraint" but only in the last case the child is in fact deleted. (Unless they mean with "dependent object" an object that participates in an identifying relationship which would be an unusual terminology though.)
Do this: Step 1: Your String
String str = ";;;;;;\n" +
"Name, number, address;;;;;;\n" +
"01.01.12-16.02.12;;;;;;\n" +
";;;;;;\n" +
";;;;;;";
Step 2: Just replace all "\n" with "%n" the result looks like this
String str = ";;;;;;%n" +
"Name, number, address;;;;;;%n" +
"01.01.12-16.02.12;;;;;;%n" +
";;;;;;%n" +
";;;;;;";
Notice I've just put "%n" in place of "\n"
Step 3: Now simply call format()
str=String.format(str);
That's all you have to do.
Cookies are stored in browser as a text file format.It stores limited amount of data, up to 4kb[4096bytes].A single Cookie can not hold multiple values but yes we can have more than one cookie.
Cookies are easily accessible so they are less secure. The setcookie() function must appear BEFORE the tag.
Sessions are stored in server side.There is no such storage limit on session .Sessions can hold multiple variables.Since they are not easily accessible hence are more secure than cookies.
I would use:
CAST
(
CAST(YEAR(DATEFIELD) as varchar(4)) + '/' CAST(MM(DATEFIELD) as varchar(2)) + '/' CAST(DD(DATEFIELD) as varchar(2)) as datetime
)
Thus effectively creating a new field from the date field you already have.
Yes it is possible
You can do this using only
HTML
You need to set default select optiondisabled=""

<option>Option 1</option>
<option>Option 2</option>

sys.stdout = self._string_io = StringIO()

>>> print('asdf')
>>> s = str(out)
>>> print('bsdf')
>>> print(s, out)
'asdf\n' 'asdf\nbsdf\n'
Not directly: you need a pair getter/setter with an "addListener/removeListener" interface of some sort... or an NPAPI plugin (but that's another story altogether).

Following code solved my issue:
1) Added import org.apache.log4j.{Level, Logger}
in import section
2) Added following line after creation of spark context object i.e. after val sc = new SparkContext(conf)
:

Can't you just use a Definite Assignment Assertion? (See https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-7.html#definite-assignment-assertions)
i.e. declaring the property as makes!: any[];
The ! assures typescript that there definitely will be a value at runtime.
Sorry I haven't tried this in angular but it worked great for me when I was having the exact same problem in React.

you can check this code . i hope you will easily understand.
Answer for a limited, specific situation: assuming you want to delete the files while maintainig the subfolders tree, you could use a recursive algorithm:
import os
def recursively_remove_files(f):
if os.path.isfile(f):
os.unlink(f)
elif os.path.isdir(f):
for fi in os.listdir(f):
recursively_remove_files(os.path.join(f, fi))
recursively_remove_files(my_directory)
Maybe slightly off-topic, but I think many would find it useful
You can use following regular expression construct
Punctuation: One of !"#$%&'()*+,-./:;<=>?@[]^_`{|}~
inputString.replaceAll("\\p{Punct}", "");
I set .navbar-brand { min-height: inherit }
which solved the issue for me (thanks @creimers for inspiration).
This function should work. this has the photo parameter that holds the base64 string and also path to an existing image directory should you already have an existing image you want to unlink while you save the new one.
public function convertBase64ToImage($photo = null, $path = null) {
if (!empty($photo)) {
$photo = str_replace('data:image/png;base64,', '', $photo);
$photo = str_replace(' ', '+', $photo);
$photo = str_replace('data:image/jpeg;base64,', '', $photo);
$photo = str_replace('data:image/gif;base64,', '', $photo);
$entry = base64_decode($photo);
$image = imagecreatefromstring($entry);
$fileName = time() . ".jpeg";
$directory = "uploads/customer/" . $fileName;
header('Content-type:image/jpeg');
if (!empty($path)) {
if (file_exists($path)) {
unlink($path);
}
}
$saveImage = imagejpeg($image, $directory);
imagedestroy($image);
if ($saveImage) {
return $fileName;
} else {
return false; // image not saved
}
}
}
More generic way in case qs
has more than one dictionaries:
[int(v) for lst in qs for k, v in lst.items()]
--
>>> qs = [{u'a': 15L, u'b': 9L, u'a': 16L}, {u'a': 20, u'b': 35}]
>>> result_list = [int(v) for lst in qs for k, v in lst.items()]
>>> result_list
[16, 9, 20, 35]
Take a look at http://json.org/. It claims a bit different list of escaped characters than Chris proposed.
\"
\\
\/
\b
\f
\n
\r
\t
\u four-hex-digits
I think this is what you want:
>>> def twoDigitHex( number ):
... return '%02x' % number
...
>>> twoDigitHex( 2 )
'02'
>>> twoDigitHex( 255 )
'ff'
To invoke Firefox Browser headlessly, you can set the headless
property through Options()
class as follows:
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
options = Options()
options.headless = True
driver = webdriver.Firefox(options=options, executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe')
driver.get("http://google.com/")
print ("Headless Firefox Initialized")
driver.quit()
There's another way to accomplish headless mode. If you need to disable or enable the headless mode in Firefox, without changing the code, you can set the environment variable MOZ_HEADLESS
to whatever if you want Firefox to run headless, or don't set it at all.
This is very useful when you are using for example continuous integration and you want to run the functional tests in the server but still be able to run the tests in normal mode in your PC.
$ MOZ_HEADLESS=1 python manage.py test # testing example in Django with headless Firefox
or
$ export MOZ_HEADLESS=1 # this way you only have to set it once
$ python manage.py test functional/tests/directory
$ unset MOZ_HEADLESS # if you want to disable headless mode

Here's mine:
git remote --verbose | grep origin | grep fetch | cut -f2 | cut -d' ' -f1
no better than the others, but I made it a bash function so I can drop in the remote name if it isn't origin.
grurl () {
xx_remote=$1
[ -z "$xx_remote" ] && xx_remote=origin
git remote --verbose | grep "$1" | grep fetch | cut -f2 | cut -d' ' -f1
unset xx_remote
}
There's no such concept as an integer with padding. How many legs do you have - 2, 02 or 002? They're the same number. Indeed, even the "2" part isn't really part of the number, it's only relevant in the decimal representation.
If you need padding, that suggests you're talking about the textual representation of a number... i.e. a string.
You can achieve that using string formatting options, e.g.
string text = value.ToString("0000000");
or
string text = value.ToString("D7");

Make a list of items, based on their weights
:
items = [1, 2, 3, 4, 5, 6]
probabilities= [0.1, 0.05, 0.05, 0.2, 0.4, 0.2]
# if the list of probs is normalized (sum(probs) == 1), omit this part
prob = sum(probabilities) # find sum of probs, to normalize them
c = (1.0)/prob # a multiplier to make a list of normalized probs
probabilities = map(lambda x: c*x, probabilities)
print probabilities
ml = max(probabilities, key=lambda x: len(str(x)) - str(x).find('.'))
ml = len(str(ml)) - str(ml).find('.') -1
amounts = [ int(x*(10**ml)) for x in probabilities]
itemsList = list()
for i in range(0, len(items)): # iterate through original items
itemsList += items[i:i+1]*amounts[i]
# choose from itemsList randomly
print itemsList
An optimization may be to normalize amounts by the greatest common divisor, to make the target list smaller.
Also, this might be interesting.
The following is a jQuery function call:
$(...);
Which is the "jQuery function." $
is a function, and $(...)
is you calling that function.
The first parameter you've supplied is the following:
function() {}
The parameter is a function that you specified, and the $
function will call the supplied method when the DOM finishes loading.
1.) you cannot use big border on parent -- in case you want to have a specific border
2.) you cannot add margin -- in case your parent is a part of some other container and you want your parent to take the full width of that grand parent.
The Only Solution that should be applicable is to wrap your children's in an another container so that your parent becomes the grandparent and then apply padding to the new children's Wrapper / Parent. Or you can directly apply padding to the children.
In your case:
.css-sux{
padding: 0px 10px 10px 10px;
}
Not too sure to add opacity via CSS is such a good idea.
Opacity has that funny way to be applied to all content and childs from where you set it, with unexpected results in mixed of colours.
It has no really purpose in that case , for a bg color, in my opinion.
If you'd like to lay it hover the bg image, then you may use multiple backgrounds.
this color transparent could be applyed via an extra png repeated (or not with background-position),
CSS gradient (radial-) linear-gradient with rgba colors (starting and ending with same color) can achieve this as well. They are treated as background-image and can be used as filter.
Idem for text, if you want them a bit transparent, use rgba (okay to put text-shadow together).
I think that today, we can drop funny behavior of CSS opacity.
Here is a mixed of rgba used for opacity if you are curious dabblet.com/gist/5685845
webpack solution
If you got this error while working in React with webpack and HMR.
You need to create template index.html
and save it in src
folder:
<html>
<body>
<div id="root"></root>
</body>
</html>
Now when we have template with id="root"
we need to tell webpack to generate index.html which will mirror our index.html
file.
To do that:
plugins: [
new HtmlWebpackPlugin({
title: "Application name",
template: './src/index.html'
})
],
template
property will tell webpack how to build index.html
file.
Actually you can fix it with following steps -
cls.__dict__
{'isFilled':True}
or {'isFilled':False}
depending upon what you have set.del cls.__dict__['isFilled']
In this case, we delete the entry which overrides the method as mentioned by BrenBarn.
Seaborn's barplot returns an axis-object (not a figure). This means you can do the following:
import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
fake = pd.DataFrame({'cat': ['red', 'green', 'blue'], 'val': [1, 2, 3]})
ax = sns.barplot(x = 'val', y = 'cat',
data = fake,
color = 'black')
ax.set(xlabel='common xlabel', ylabel='common ylabel')
plt.show()
I did
msgbox "TEXT HERE",3,"TITLE HERE"
If Yes=true then
(result)
else
msgbox "Closing..."
You can't use the ID while inserting, neither do you need it. MySQL does not even know the ID when you are inserting that record. You could just save "sahf4d2fdd45"
in the payment_code
table and use id
and payment_code
later on.
If you really need your payment_code to have the ID in it then UPDATE the row after the insert to add the ID.
Thank for the answers,
The border is removed for Internet Explorer, but this there for Firefox.
So, I added this class to the img
:
.clearBorder{border:none;}
And it worked!
Style the ::-ms-clear
pseudo-element for the box:
.someinput::-ms-clear {
display: none;
}

Update 1/5/2018 - over the last 9 years, my thinking has evolved considerably on this topic. I tend to live a little closer to the bleeding edge in our industry than the majority (though certainly not pushing the boundaries nearly as much as a lot of really smart people out there). I've been an architect at varying levels from application, to solution, to enterprise, at multiple companies large and small. I've come to the conclusion that the future in our technology industry is one mostly without architects. If this sounds crazy to you, wait a few years and your company will probably catch up, or your competitors who figure it out will catch up with (and pass) you. The fundamental problem is that "architecture" is nothing more or less than the sum of all the decisions that have been made about your application/solution/portfolio. So the title "architect" really means "decider". That says a lot, also by what it doesn't say. It doesn't say "builder". Creating a career path / hierarchy that implicitly tells people "building" is lower than "deciding", and "deciders" are not directly responsible (by the difference in title) for "building". People who are still hanging on to their architect title will chafe at this and protest "but I am hands-on!" Great, if you're just a builder then give up your meaningless title and stop setting yourself apart from the other builders. Companies that emphasize "all builders are deciders, and all deciders are builders" will move faster than their competitors. We use the title "engineer" for everyone, and "engineer" means deciding and building.
Original answer:
For people who have never worked in a very large organization (or have, but it was a dysfunctional one), "architect" may have left a bad taste in their mouth. However, it is not only a legitimate role, but a highly strategic one for smart companies.
When an application becomes so vast and complex that dealing with the overall technical vision and planning, and translating business needs into technical strategy becomes a full-time job, that is an application architect. Application architects also often mentor and/or lead developers, and know the code of their responsible application(s) well.
When an organization has so many applications and infrastructure inter-dependencies that it is a full-time job to ensure their alignment and strategy without being involved in the code of any of them, that is a solution architect. Solution architect can sometimes be similar to an application architect, but over a suite of especially large applications that comprise a logical solution for a business.
When an organization becomes so large that it becomes a full-time job to coordinate the high-level planning for the solution architects, and frame the terms of the business technology strategy, that role is an enterprise architect. Enterprise architects typically work at an executive level, advising the CxO office and its support functions as well as the business as a whole.
There are also infrastructure architects, information architects, and a few others, but in terms of total numbers these comprise a smaller percentage than the "big three".
Note: numerous other answers have said there is "no standard" for these titles. That is not true. Go to any Fortune 1000 company's IT department and you will find these titles used consistently.
The two most common misconceptions about "architect" are:
These misconceptions come from a lot of architects doing a pretty bad job, and organizations doing a terrible job at understanding what an architect is for. It is common to promote the top programmer into an architect role, but that is not right. They have some overlapping but not identical skillsets. The best programmer may often be, but is not always, an ideal architect. A good architect has a good understanding of many technical aspects of the IT industry; a better understanding of business needs and strategies than a developer needs to have; excellent communication skills and often some project management and business analysis skills. It is essential for architects to keep their hands dirty with code and to stay sharp technically. Good ones do.
Array and Object is passed as pass by reference or pass by value based on these two condition.
if you are changing value of that Object or array with new Object or Array then it is pass by Value.
object1 = {item: "car"};
array1=[1,2,3];
here you are assigning new object or array to old one.you are not changing the value of property of old object.so it is pass by value.
if you are changing a property value of an object or array then it is pass by Reference.
object1.key1= "car";
array1[0]=9;
here you are changing a property value of old object.you are not assigning new object or array to old one.so it is pass by reference.
Code
function passVar(object1, object2, number1) {
object1.key1= "laptop";
object2 = {
key2: "computer"
};
number1 = number1 + 1;
}
var object1 = {
key1: "car"
};
var object2 = {
key2: "bike"
};
var number1 = 10;
passVar(object1, object2, number1);
console.log(object1.key1);
console.log(object2.key2);
console.log(number1);
Output: -
laptop
bike
10
You can use regular expressions like this:
SELECT * FROM pet WHERE name REGEXP 'Bob|Smith';
The WhatsApp Architecture Facebook Bought For $19 Billion explains the architecture involved in design of whatsapp.
Here is the general explanation from the link
WhatsApp server is almost completely implemented in Erlang.
Server systems that do the backend message routing are done in Erlang.
Great achievement is that the number of active users is managed with a really small server footprint. Team consensus is that it is largely because of Erlang.
Interesting to note Facebook Chat was written in Erlang in 2009, but they went away from it because it was hard to find qualified programmers.
WhatsApp server has started from ejabberd
Ejabberd is a famous open source Jabber server written in Erlang.
Originally chosen because its open, had great reviews by developers, ease of start and the promise of Erlang’s long term suitability for large communication system.
The next few years were spent re-writing and modifying quite a few parts of ejabberd, including switching from XMPP to internally developed protocol, restructuring the code base and redesigning some core components, and making lots of important modifications to Erlang VM to optimize server performance.
To handle 50 billion messages a day the focus is on making a reliable system that works. Monetization is something to look at later, it’s far far down the road.
A primary gauge of system health is message queue length. The message queue length of all the processes on a node is constantly monitored and an alert is sent out if they accumulate backlog beyond a preset threshold. If one or more processes falls behind that is alerted on, which gives a pointer to the next bottleneck to attack.
Multimedia messages are sent by uploading the image, audio or video to be sent to an HTTP server and then sending a link to the content along with its Base64 encoded thumbnail (if applicable).
Some code is usually pushed every day. Often, it’s multiple times a day, though in general peak traffic times are avoided. Erlang helps being aggressive in getting fixes and features into production. Hot-loading means updates can be pushed without restarts or traffic shifting. Mistakes can usually be undone very quickly, again by hot-loading. Systems tend to be much more loosely-coupled which makes it very easy to roll changes out incrementally.
What protocol is used in Whatsapp app? SSL socket to the WhatsApp server pools. All messages are queued on the server until the client reconnects to retrieve the messages. The successful retrieval of a message is sent back to the whatsapp server which forwards this status back to the original sender (which will see that as a "checkmark" icon next to the message). Messages are wiped from the server memory as soon as the client has accepted the message
How does the registration process work internally in Whatsapp? WhatsApp used to create a username/password based on the phone IMEI number. This was changed recently. WhatsApp now uses a general request from the app to send a unique 5 digit PIN. WhatsApp will then send a SMS to the indicated phone number (this means the WhatsApp client no longer needs to run on the same phone). Based on the pin number the app then request a unique key from WhatsApp. This key is used as "password" for all future calls. (this "permanent" key is stored on the device). This also means that registering a new device will invalidate the key on the old device.
For modern browsers, use td:nth-child(2)
for the second td
, and td:nth-child(3)
for the third. Remember that these retrieve the second and third td
for every row.
If you need compatibility with IE older than version 9, use sibling combinators or JavaScript as suggested by Tim. Also see my answer to this related question for an explanation and illustration of his method.
It is Widget.ProgressBar.Horizontal
on my phone, if I set android:indeterminate="true"
You can do this conversion with the OpenSSL library
Windows binaries can be found here:
http://www.slproweb.com/products/Win32OpenSSL.html
Once you have the library installed, the command you need to issue is:
openssl x509 -in mycert.crt -out mycert.pem -outform PEM
This is a slightly difficult problem, which I think reduces to: "Test if two lists are permutations of each other."
I believe the solutions provided by others only indicate whether the 2 lists contain the same unique elements. This is a necessary but insufficient test, for example
{1, 1, 2, 3}
is not a permutation of {3, 3, 1, 2}
although their counts are equal and they contain the same distinct elements.
I believe this should work though, although it's not the most efficient:
static bool ArePermutations<T>(IList<T> list1, IList<T> list2)
{
if(list1.Count != list2.Count)
return false;
var l1 = list1.ToLookup(t => t);
var l2 = list2.ToLookup(t => t);
return l1.Count == l2.Count
&& l1.All(group => l2.Contains(group.Key) && l2[group.Key].Count() == group.Count());
}
Simple answer: You should use RecyclerView in a situation where you want to show a lot of items, and the number of them is dynamic. ListView should only be used when the number of items is always the same and is limited to the screen size.
You find it harder because you are thinking just with the Android library in mind.
Today there exists a lot of options that help you build your own adapters, making it easy to build lists and grids of dynamic items that you can pick, reorder, use animation, dividers, add footers, headers, etc, etc.
Don't get scared and give a try to RecyclerView, you can starting to love it making a list of 100 items downloaded from the web (like facebook news) in a ListView and a RecyclerView, you will see the difference in the UX (user experience) when you try to scroll, probably the test app will stop before you can even do it.
I recommend you to check this two libraries for making easy adapters:
You can select multiple fields using linq Select as shown above in various examples this will return as an Anonymous Type. If you want to avoid this anonymous type here is the simple trick.
var items = listObject.Select(f => new List<int>() { f.Item1, f.Item2 }).SelectMany(item => item).Distinct();
I think this solves your problem
strcmp()
and ===
are both case sensitive but ===
is much faster
sample code: http://snipplr.com/view/758/
The problem with shelling out to a batch file or EXE is that a service may or may not have the permissions required to run the external app.
The cleanest way to do this that I have found is to use the OnStop() method, which is the entry point for the Service Control Manager. Then all your cleanup code will run, and you won't have any hanging sockets or other processes, assuming your stop code is doing its job.
To do this you need to set a flag before you terminate that tells the OnStop method to exit with an error code; then the SCM knows that the service needs to be restarted. Without this flag you won't be able to stop the service manually from the SCM. This also assumes you have set up the service to restart on an error.
Here's my stop code:
...
bool ABORT;
protected override void OnStop()
{
Logger.log("Stopping service");
WorkThreadRun = false;
WorkThread.Join();
Logger.stop();
// if there was a problem, set an exit error code
// so the service manager will restart this
if(ABORT)Environment.Exit(1);
}
If the service runs into a problem and needs to restart, I launch a thread that stops the service from the SCM. This allows the service to clean up after itself:
...
if(NeedToRestart)
{
ABORT = true;
new Thread(RestartThread).Start();
}
void RestartThread()
{
ServiceController sc = new ServiceController(ServiceName);
try
{
sc.Stop();
}
catch (Exception) { }
}
Use the %
wildcard, which matches any number of characters.
SELECT * FROM Accounts WHERE Username LIKE '%query%'
I solved this like this:
<section className="container-fluid">
<div className="row justify-content-center">
<article className="d-flex flex-column justify-content-center align-items-center vh-100">
<!-- content -->
</article>
</div>
</section>
You can try these:
function union(a, b) {
return a.concat(b).reduce(function(prev, cur) {
if (prev.indexOf(cur) === -1) prev.push(cur);
return prev;
}, []);
}
or
function union(a, b) {
return a.concat(b.filter(function(el) {
return a.indexOf(el) === -1;
}));
}
Do i need to modify the headers and just echo it or something?
exactly.
Send a header("content-type: image/your_image_type");
and the data afterwards.
Using EntityFramework, you can go with a solution like this. I use this code to initialize e2e tests. De prevent sql injection attacks, make sure not to generate this script based on user input or use command parameters for this (see overload of ExecuteSqlCommand that accepts parameters).
public static void ExecuteSqlScript(string sqlScript)
{
using (MyEntities dataModel = new MyEntities())
{
// split script on GO commands
IEnumerable<string> commands =
Regex.Split(
sqlScript,
@"^\s*GO\s*$",
RegexOptions.Multiline | RegexOptions.IgnoreCase);
foreach (string command in commands)
{
if (command.Trim() != string.Empty)
{
dataModel.Database.ExecuteSqlCommand(command);
}
}
}
}

Rather than take the approach of serializing and deserializing JavaScript objects to an internal format the approach here is to serialize JavaScript objects out to native JavaScript. This has the advantage that the format is totally agnostic from the serializer, and the object can be recreated simply by calling eval().
copy tablename from 'filepath\filename' DELIMITERS '=' ENCODING 'WIN1252';
you can try this to handle UTF8 encoding.
I would like to extend the answer of @dzintars about the Cygwin version of pkg-config in that focus how should one use it properly with CMake, because I see various comments about CMake in this topic.
I have experienced many troubles with CMake + Cygwin's pkg-config and I want to share my experience how to avoid them.
1. The symlink C:/Cygwin64/bin/pkg-config -> pkgconf.exe does not work in Windows console.
It is not a native Windows .lnk symlink and it won't be callable in Windows console cmd.exe even if you add ".;" to your %PATHEXT% (see https://www.mail-archive.com/[email protected]/msg104088.html).
It won't work from CMake, because CMake calls pkg-config with the method execute_process() (FindPkgConfig.cmake) which opens a new cmd.exe.
Solution: Add -DPKG_CONFIG_EXECUTABLE=C:/Cygwin64/bin/pkgconf.exe to the CMake command line (or set it in CMakeLists.txt).
2. Cygwin's pkg-config recognizes only Cygwin paths in PKG_CONFIG_PATH (no Windows paths).
For example, on my system the .pc files are located in C:\Cygwin64\usr\x86_64-w64-mingw32\sys-root\mingw\lib\pkgconfig. The following three paths are valid, but only path C works in PKG_CONFIG_PATH:
Solution: add .pc files location always as a Cygwin path into PKG_CONFIG_PATH.
3) CMake converts forward slashes to backslashes in PKG_CONFIG_PATH on Cygwin.
It happens due to the bug https://gitlab.kitware.com/cmake/cmake/-/issues/21629. It prevents using the workaround described in [2].
Solution: manually update the function _pkg_set_path_internal() in the file C:/Program Files/CMake/share/cmake-3.x/Modules/FindPkgConfig.cmake. Comment/remove the line:
file(TO_NATIVE_PATH "${_pkgconfig_path}" _pkgconfig_path)
4) CMAKE_PREFIX_PATH, CMAKE_FRAMEWORK_PATH, CMAKE_APPBUNDLE_PATH have no effect on pkg-config in Cygwin.
Reason: the bug https://gitlab.kitware.com/cmake/cmake/-/issues/21775.
Solution: Use only PKG_CONFIG_PATH as an environment variable if you run CMake builds on Cygwin. Forget about CMAKE_PREFIX_PATH, CMAKE_FRAMEWORK_PATH, CMAKE_APPBUNDLE_PATH.
You can use ES6 backtick syntax too
<a href={`/customer/${item._id}`} >{item.get('firstName')} {item.get('lastName')}</a>
Anybody facing the same issues, follow the simple steps:
Import the project android
from downloaded zxing-master
zip file using option Import project (Eclipse ADT, Gradle, etc.)
and add the dollowing 2 lines of codes in your app level build.gradle
file and and you are ready to run.
So simple, yahh...
dependencies {
// https://mvnrepository.com/artifact/com.google.zxing/core
compile group: 'com.google.zxing', name: 'core', version: '3.2.1'
// https://mvnrepository.com/artifact/com.google.zxing/android-core
compile group: 'com.google.zxing', name: 'android-core', version: '3.2.0'
}
You can always find latest version core
and android core
from below links:
https://mvnrepository.com/artifact/com.google.zxing/core/3.2.1 https://mvnrepository.com/artifact/com.google.zxing/android-core/3.2.0
UPDATE (29.05.2019)
Add these dependencies instead:
dependencies {
implementation 'com.google.zxing:core:3.4.0'
implementation 'com.google.zxing:android-core:3.3.0'
}
It turns out that the string needed to be turned into a bytearray and to do this I editted the code to
ser.write("%01#RDD0010000107**\r".encode())
This solved the problem
Reading the Spark documentation I found an easier solution.
Since version 1.4 of spark there is a function drop(col)
which can be used in pyspark on a dataframe.
You can use it in two ways
df.drop('age').collect()
df.drop(df.age).collect()
Wildcards worked for me when the string I was searching for could be entered manually. However, I wanted to store this string in another cell and refer to it. I couldn't figure out how to do this with wildcards so I ended up doing the following:
A1 is the cell containing my search string. B and C are the columns within which I want to count the number of instances of A1, including within strings:
=COUNTIF(ARRAYFORMULA(ISNUMBER(SEARCH(A1, B:C))), TRUE)
You can use String.Join method to combine items:
var str = String.Join(",", lst);
There's no easy way to find out the memory size of a python object. One of the problems you may find is that Python objects - like lists and dicts - may have references to other python objects (in this case, what would your size be? The size containing the size of each object or not?). There are some pointers overhead and internal structures related to object types and garbage collection. Finally, some python objects have non-obvious behaviors. For instance, lists reserve space for more objects than they have, most of the time; dicts are even more complicated since they can operate in different ways (they have a different implementation for small number of keys and sometimes they over allocate entries).
There is a big chunk of code (and an updated big chunk of code) out there to try to best approximate the size of a python object in memory.
You may also want to check some old description about PyObject (the internal C struct that represents virtually all python objects).
Yeah, awendt answer is perfect. I'll just show my working code... I had the context.succeed('Blah'); line right after the reqPost.end(); line. Moving it to where I show below solved everything.
console.log('GW1');
var https = require('https');
exports.handler = function(event, context) {
var body='';
var jsonObject = JSON.stringify(event);
// the post options
var optionspost = {
host: 'the_host',
path: '/the_path',
method: 'POST',
headers: {
'Content-Type': 'application/json',
}
};
var reqPost = https.request(optionspost, function(res) {
console.log("statusCode: ", res.statusCode);
res.on('data', function (chunk) {
body += chunk;
});
context.succeed('Blah');
});
reqPost.write(jsonObject);
reqPost.end();
};
TL;DR:
The ActionListener
s (there can be multiple) execute in the order they were registered BEFORE the action
Long Answer:
A business action
typically invokes an EJB service and if necessary also sets the final result and/or navigates to a different view
if that is not what you are doing an actionListener
is more appropriate i.e. for when the user interacts with the components, such as h:commandButton
or h:link
they can be handled by passing the name of the managed bean method in actionListener
attribute of a UI Component or to implement an ActionListener
interface and pass the implementation class name to actionListener
attribute of a UI Component.
Here's what you need:
public static DateTime UnixTimeStampToDateTime( double unixTimeStamp )
{
// Unix timestamp is seconds past epoch
System.DateTime dtDateTime = new DateTime(1970,1,1,0,0,0,0,System.DateTimeKind.Utc);
dtDateTime = dtDateTime.AddSeconds( unixTimeStamp ).ToLocalTime();
return dtDateTime;
}
Or, for Java (which is different because the timestamp is in milliseconds, not seconds):
public static DateTime JavaTimeStampToDateTime( double javaTimeStamp )
{
// Java timestamp is milliseconds past epoch
System.DateTime dtDateTime = new DateTime(1970,1,1,0,0,0,0,System.DateTimeKind.Utc);
dtDateTime = dtDateTime.AddMilliseconds( javaTimeStamp ).ToLocalTime();
return dtDateTime;
}
For those using the ANT task wsimport
, a way of passing the option as suggested by @CMFly and specified in the documentation is the following:
<wsimport
<!-- ... -->
fork="true"
>
<jvmarg value="-Djavax.xml.accessExternalSchema=all"/>
</wsimport>
A generic piece of code that will work for multiple columns. This can also be used if there is a need to conditionally implement search functionality in the application.
search_key = "abc"
search_args = [col.ilike('%%%s%%' % search_key) for col in ['col1', 'col2', 'col3']]
query = Query(table).filter(or_(*search_args))
session.execute(query).fetchall()
Note: the %%
are important to skip % formatting the query.
command+fn+F12 is correct. Lacking of button fn the F12 is used adjust the volume.
try to change your build.gradle with these value:
android { compileSdkVersion 18 buildToolsVersion '21.0.1'
defaultConfig {
minSdkVersion 18
targetSdkVersion 18
}
if using TypeScript, you can use the spread operator (...
)
var json = {...json1,...json2}
To avoid throw a exception while "p" or "p.User" is None, you can use:
{{ (p and p.User and p.User['first_name']) or "default_value" }}
It does not work because your script in JSFiddle is running inside it's own scope (see the "OnLoad" drop down on the left?).
One way around this is to bind your event handler in javascript (where it should be):
document.getElementById('optionID').onchange = function () {
document.getElementById("message").innerHTML = "Having a Baby!!";
};
Another way is to modify your code for the fiddle environment and explicitly declare your function as global so it can be found by your inline event handler:
window.changeMessage() {
document.getElementById("message").innerHTML = "Having a Baby!!";
};
?
If the files are already in version control you need to remove them manually.
