And if you neither want to use @Autowire nor injecting @Value you can simply do (with fallback included):
System.getProperty("spring.profiles.active", "unknown");
This will return any active profile (or fallback to 'unknown').
Try this:
insert into [table] ([data])
output inserted.id, inserted.data into table2
select [data] from [external_table]
UPDATE: Re:
Denis - this seems very close to what I want to do, but perhaps you could fix the following SQL statement for me? Basically the [data] in [table1] and the [data] in [table2] represent two different/distinct columns from [external_table]. The statement you posted above only works when you want the [data] columns to be the same.
INSERT INTO [table1] ([data])
OUTPUT [inserted].[id], [external_table].[col2]
INTO [table2] SELECT [col1]
FROM [external_table]
It's impossible to output external columns in an insert
statement, so I think you could do something like this
merge into [table1] as t
using [external_table] as s
on 1=0 --modify this predicate as necessary
when not matched then insert (data)
values (s.[col1])
output inserted.id, s.[col2] into [table2]
;
Try INC_DIR=../ ../StdCUtil
.
Then, set CCFLAGS=-c -Wall $(addprefix -I,$(INC_DIR))
EDIT: Also, modify your #include
to be #include <StdCUtil/split.h>
so that the compiler knows to use -I rather than local path of the .cpp using the #include
.
You have two typing errors in your code:
struct timeval,
should be
struct timeval
and after the printf()
parenthesis you need a semicolon.
Also, depending on the compiler, so simple a cycle might just be optimized out, giving you a time of 0 microseconds whatever you do.
Finally, the time calculation is wrong. You only take into accounts the seconds, ignoring the microseconds. You need to get the difference between seconds, multiply by one million, then add "after" tv_usec
and subtract "before" tv_usec
. You gain nothing by casting an integer number of seconds to a float.
I'd suggest checking out the man page for struct timeval
.
This is the code:
#include <stdio.h>
#include <sys/time.h>
int main (int argc, char** argv) {
struct timeval tvalBefore, tvalAfter; // removed comma
gettimeofday (&tvalBefore, NULL);
int i =0;
while ( i < 10000) {
i ++;
}
gettimeofday (&tvalAfter, NULL);
// Changed format to long int (%ld), changed time calculation
printf("Time in microseconds: %ld microseconds\n",
((tvalAfter.tv_sec - tvalBefore.tv_sec)*1000000L
+tvalAfter.tv_usec) - tvalBefore.tv_usec
); // Added semicolon
return 0;
}
In my case the problem was that on the server, a different appsettings.json file was used by the application.
Make sure you are using Javascript module or not?!
if using js6 modules your html events attributes won't work.
in that case you must bring your function from global scope to module scope. Just add this to your javascript file:
window.functionName= functionName;
example:
<h1 onClick="functionName">some thing</h1>
That's not really a question of aesthetics, but indeed a technical difference. The directory thinking of it is totally correct and pretty much explaining everything. Let's work it out:
You have a fixed directory structure on your web server and only static files like images, html and so on — no server side scripts or whatsoever.
A browser requests /index.htm
, it exists and is delivered to the client. Later you have lots of - let's say - DVD movies reviewed and a html page for each of them in the /dvd/
directory. Now someone requests /dvd/adams_apples.htm
and it is delivered because it is there.
At some day, someone just requests /dvd/
- which is a directory and the server is trying to figure out what to deliver. Besides access restrictions and so on there are two possibilities: Show the user the directory content (I bet you already have seen this somewhere) or show a default file (in Apache it is: DirectoryIndex: sets the file that Apache will serve if a directory is requested.
)
So far so good, this is the expected case. It already shows the difference in handling, so let's get into it:
(Which is by the way completely understandable.) So, you did something entirely wrong and instead of uploading /dvd/the_big_lebowski.htm
you uploaded that file as dvd
(with no extension) to /
.
Someone bookmarked your /dvd/
directory listing (of course you didn't want to create and always update that nifty index.htm
) and is visiting your web-site. Directory content is delivered - all fine.
Someone heard of your list and is typing /dvd
. And now it is screwed. Instead of your DVD directory listing the server finds a file with that name and is delivering your Big Lebowski file.
So, you delete that file and tell the guy to reload the page. Your server looks for the /dvd
file, but it is gone. Most servers will then notice that there is a directory with that name and tell the client that what it was looking for is indeed somewhere else. The response will most likely be be:
Status Code:301 Moved Permanently
with Location: http://[...]/dvd/
So, totally ignoring what you think about directories or files, the server only can handle such stuff and - unless told differently - decides for you about the meaning of "slash or not".
Finally after receiving this response, the client loads /dvd/
and everything is fine.
Is it fine? No.
You have some dynamic page where everything is passed to /index.php
and gets processed. Everything worked quite good until now, but that entire thing starts to feel slower and you investigate.
Soon, you'll notice that /dvd/list
is doing exactly the same: Redirecting to /dvd/list/
which is then internally translated into index.php?controller=dvd&action=list
. One additional request - but even worse! customer/login
redirects to customer/login/
which in turn redirects to the HTTPS URL of customer/login/
. You end up having tons of unnecessary HTTP redirects (= additional requests) that make the user experience slower.
Most likely you have a default directory index here, too: index.php?controller=dvd
with no action
simply internally loads index.php?controller=dvd&action=list
.
If it ends with /
it can never be a file. No server guessing.
Slash or no slash are entirely different meanings. There is a technical/resource difference between "slash or no slash", and you should be aware of it and use it accordingly. Just because the server most likely loads /dvd/index.htm
- or loads the correct script stuff - when you say /dvd
: It does it, but not because you made the right request. Which would have been /dvd/
.
Omitting the slash even if you indeed mean the slashed version gives you an additional HTTP request penalty. Which is always bad (think of mobile latency) and has more weight than a "pretty URL" - especially since crawlers are not as dumb as SEOs believe or want you to believe ;)

The conflict message:
CONFLICT (delete/modify): res/layout/dialog_item.xml deleted in dialog and modified in HEAD
means that res/layout/dialog_item.xml
was deleted in the 'dialog' branch you are merging, but was modified in HEAD (in the branch you are merging to).
So you have to decide whether
git rm res/layout/dialog_item.xml
"or
git add res/layout/dialog_item.xml
"Then you finalize merge with "git commit
".
Note that git will warn you that you are creating a merge commit, in the (rare) case where it is something you don't want. Probably remains from the days where said case was less rare.
h1 is a block level element. You will need to use something like span instead as it is an inline level element (ie: it does not span the whole row).
In your case, I would suggest the following:
style.css
.highlight
{
background-color: green;
}
html
<span class="highlight">only the text will be highlighted</span>
As @wes-floyd and @zpon wrote, add these parameters to SSH to bypass "Are you sure you want to continue connecting (yes/no)?"
-o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no
This works, but there might be better solutions.
asking="hello! what's your name?"
asking = ''.join([c for c in asking if c not in ('!', '?')])
print asking
You can use the below sample, also you dont need the else clause to print nothing!
<?php if ( ($cart->count_product) > 0) { ?>
<div class="my_class">
<?php print $cart->count_product; ?>
</div>
<?php } ?>
On windows you can use a graphic interface of scp using winSCP. A nice free software that implements SFTP protocol.
Use following formula:
=CONCATENATE(LOWER(MID(A1,1,1)),LOWER( B1))
for
Josh Smith = jsmith
note that A1 contains name and B1 contains surname
$filterQuery = $this->queryFactory->create(QueryInterface::TYPE_BOOL, ['must' => $queries,'should'=>$queriesGeo]);
In must
you need to add the query condition array which you want to work with AND
and in should
you need to add the query condition which you want to work with OR
.
You can check this: https://github.com/Smile-SA/elasticsuite/issues/972

$('#fire').on('click', function (e) {
//your awesome code here
})
You just need:
if (!empty($_POST['search_term']) && !empty($_POST['postcode']))
isset && !empty
is redundant.
I might be stating the obvious here but why not simply implement the "default" parameter yourself?
public class Foo() {
public void func(String s){
func(s, true);
}
public void func(String s, boolean b){
//your code here
}
}
for the default, you would either use
func("my string");
and if you wouldn't like to use the default, you would use
func("my string", false);
Starting with AspNetCore 2.0, it's recommended to use ContentResult
instead of the Produce
attribute in this case. See: https://github.com/aspnet/Mvc/issues/6657#issuecomment-322586885
This doesn't rely on serialization nor on content negotiation.
[HttpGet]
public ContentResult Index() {
return new ContentResult {
ContentType = "text/html",
StatusCode = (int)HttpStatusCode.OK,
Content = "<html><body>Hello World</body></html>"
};
}
One can also follow the below steps : Spyder -> Tools -> Open Command Prompt -> write the command "pip install html5lib"
You typically restore purchases with this code:
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
It will reinvoke -paymentQueue:updatedTransactions
on the observer(s) for the purchased items. This is useful for users who reinstall the app after deletion or install it on a different device.
Not all types of In-App purchases can be restored.
There is no standard Unix command, AFAIK. I haven't used Sun OS, but on Linux, you can use this:
cat /proc/cpuinfo
Sorry that it is Linux, not Sun OS. There is probably something similar though for Sun OS.
Use:
Add a new item, NSAppTransportSecurity, in the plist file with type Dictionary, then add sub item NSAllowsArbitraryLoads in dictionary of type Boolean, and set bool value YES. This works for me.
If you want to load csv as a dataframe then you can do the following:
from pyspark.sql import SQLContext
sqlContext = SQLContext(sc)
df = sqlContext.read.format('com.databricks.spark.csv') \
.options(header='true', inferschema='true') \
.load('sampleFile.csv') # this is your csv file
It worked fine for me.
If you have to do this inline (such as when using an input box),
here is a quick hack that worked for me: surround your (image link in this case)
in a div
with style="text-align:center"
<div style="text-align:center">
<a title="Example Image: Google Logo" href="https://www.google.com/"
target="_blank" rel="noopener"><img src="https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png" alt="Google Logo. Click to visit Google.com" border="0" data-recalc-dims="1" /></a>
<h6><strong>This text will also be centered </strong></h6>
</div> /* ends centering style */
I think what you're looking for is the locals method -
In [6]: def test(a, b):print locals()
...:
In [7]: test(1,2)
{'a': 1, 'b': 2}
I had the same problem as you a while back. I can't remember the details but the following code got things working for me. This code is used within a Spring Webflow flow, hence the RequestContext and ExternalContext classes. But the part that is most relevant to you is the doAutoLogin method.
public String registerUser(UserRegistrationFormBean userRegistrationFormBean,
RequestContext requestContext,
ExternalContext externalContext) {
try {
Locale userLocale = requestContext.getExternalContext().getLocale();
this.userService.createNewUser(userRegistrationFormBean, userLocale, Constants.SYSTEM_USER_ID);
String emailAddress = userRegistrationFormBean.getChooseEmailAddressFormBean().getEmailAddress();
String password = userRegistrationFormBean.getChoosePasswordFormBean().getPassword();
doAutoLogin(emailAddress, password, (HttpServletRequest) externalContext.getNativeRequest());
return "success";
} catch (EmailAddressNotUniqueException e) {
MessageResolver messageResolvable
= new MessageBuilder().error()
.source(UserRegistrationFormBean.PROPERTYNAME_EMAIL_ADDRESS)
.code("userRegistration.emailAddress.not.unique")
.build();
requestContext.getMessageContext().addMessage(messageResolvable);
return "error";
}
}
private void doAutoLogin(String username, String password, HttpServletRequest request) {
try {
// Must be called from request filtered by Spring Security, otherwise SecurityContextHolder is not updated
UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(username, password);
token.setDetails(new WebAuthenticationDetails(request));
Authentication authentication = this.authenticationProvider.authenticate(token);
logger.debug("Logging in with [{}]", authentication.getPrincipal());
SecurityContextHolder.getContext().setAuthentication(authentication);
} catch (Exception e) {
SecurityContextHolder.getContext().setAuthentication(null);
logger.error("Failure in autoLogin", e);
}
}
Sorry, read the question wrong the first time. You can do something like this:
declare @result varchar(max)
--must "initialize" result for this to work
select @result = ''
select @result = @result + alias
FROM aliases
WHERE username='Bob'
You can use SRV records:
_service._proto.name. TTL class SRV priority weight port target.
Service: the symbolic name of the desired service.
Proto: the transport protocol of the desired service; this is usually either TCP or UDP.
Name: the domain name for which this record is valid, ending in a dot.
TTL: standard DNS time to live field.
Class: standard DNS class field (this is always IN).
Priority: the priority of the target host, lower value means more preferred.
Weight: A relative weight for records with the same priority.
Port: the TCP or UDP port on which the service is to be found.
Target: the canonical hostname of the machine providing the service, ending in a dot.
Example:
_sip._tcp.example.com. 86400 IN SRV 0 5 5060 sipserver.example.com.
So what I think you're looking for is to add something like this to your DNS hosts file:
_sip._tcp.arboristal.com. 86400 IN SRV 10 40 25565 mc.arboristal.com.
_sip._tcp.arboristal.com. 86400 IN SRV 10 30 25566 tekkit.arboristal.com.
_sip._tcp.arboristal.com. 86400 IN SRV 10 30 25567 pvp.arboristal.com.
On a side note, I highly recommend you go with a hosting company rather than hosting the servers yourself. It's just asking for trouble with your home connection (DDoS and Bandwidth/Connection Speed), but it's up to you.
If you are using a Dockerfile, try:
ENTRYPOINT ["tail", "-f", "/dev/null"]
(Obviously this is for dev purposes only, you shouldn't need to keep a container alive unless it's running a process eg. nginx...)
One way to get this error is trying to add a usercontrol to a form while the project is set to compile as x64. Visual Studio throws the unhelpful: "Failed to load toolbox item . It will be removed from the toolbox."
Workaround is to design with "Any CPU" and compile to x64 as necessary.
I know this is old, but... Another option may be to use the FileSystemWatcher like so:
void SomeMethod()
{
System.IO.FileSystemWatcher m_Watcher = new System.IO.FileSystemWatcher();
m_Watcher.Path = path;
m_Watcher.Filter = "*.*";
m_Watcher.NotifyFilter = m_Watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.FileName | NotifyFilters.DirectoryName;
m_Watcher.Created += new FileSystemEventHandler(OnChanged);
m_Watcher.EnableRaisingEvents = true;
}
private void OnChanged(object sender, FileSystemEventArgs e)
{
string path = e.FullPath;
lock (listLock)
{
pathsToUpload.Add(path);
}
}
This would allow you to watch the directories for file changes with an extremely lightweight process, that you could then use to store the names of the files that changed so that you could back them up at the appropriate time.
So this has been quite painful for something that should be trivial. Here is what I did:
Use xcassets
I decided to use .xcassets versus the .xib for launch. I deleted the .xib. If you have images.xcassets already in your project then great, otherwise you can add one from File>New>file:
Create a Launch Image Set
Now create at a minimum a launchimage set and icon set in your .xcassets file by right clicking in the navigator area.
Update the App Icons and Launch Images Settings
Then I made sure that the "Apps icon and image sets" in my target are as below.
Very Important: Make sure the "Launch screen file" setting is blank.
Add the Images
Last but not least, the terminology used by Apple for the device selection is confusing. Initially I thought that since I am deploying for iOS8 only (iPhone Portrait), I can do this and just put in the iPhone 6 and iPhone 6+ launch images:
I quickly realized that is not the way this works and I was getting a warning: "An iPhone Retina (4-inch) launch image for iOS 7.0 and later is required."
So I had to select the iPhone under iOS 7.0 and later as well and add an Image for the iPhone 5s.
So to find out which boxes to check on the right, do not ask the question: What is my minimum iOS and device and device orientation but rather ask:
What devices out there can support my minimum iOS? Now What is the minimum iOS supported on those devices? And make sure you check all of those boxes. So for me, I am targeting iPhone 5s, 6 and 6 Plus at 8.0 but given that iPhone 5s can exist with 7.0, I need to check the 7.0 box as well to show the image placeholder. In other words, the (iOS) check box on the right shows you the minimum iOS version available for that device and you need to click it to show the image placeholder and put an image regardless of whether you are deploying at this iOS version or not.
Hope this helps somebody.
For Java < 7 you can use if-else along with Exception:
try {
// common logic to handle both exceptions
} catch (Exception ex) {
if (ex instanceof Exception1 || ex instanceof Exception2) {
}
else {
throw ex;
// or if you don't want to have to declare Exception use
// throw new RuntimeException(ex);
}
}
Edited and replaced Throwable with Exception.

Answer from Mos6y https://medium.com/@Mos6yCanSwift/swift-ios-determine-scroll-direction-d48a2327a004
I have a slightly different perspective on the difference between a DATETIME and a TIMESTAMP. A DATETIME stores a literal value of a date and time with no reference to any particular timezone. So, I can set a DATETIME column to a value such as '2019-01-16 12:15:00' to indicate precisely when my last birthday occurred. Was this Eastern Standard Time? Pacific Standard Time? Who knows? Where the current session time zone of the server comes into play occurs when you set a DATETIME column to some value such as NOW(). The value stored will be the current date and time using the current session time zone in effect. But once a DATETIME column has been set, it will display the same regardless of what the current session time zone is.
A TIMESTAMP column on the other hand takes the '2019-01-16 12:15:00' value you are setting into it and interprets it in the current session time zone to compute an internal representation relative to 1/1/1970 00:00:00 UTC. When the column is displayed, it will be converted back for display based on whatever the current session time zone is. It's a useful fiction to think of a TIMESTAMP as taking the value you are setting and converting it from the current session time zone to UTC for storing and then converting it back to the current session time zone for displaying.
If my server is in San Francisco but I am running an event in New York that starts on 9/1/1029 at 20:00, I would use a TIMESTAMP column for holding the start time, set the session time zone to 'America/New York' and set the start time to '2009-09-01 20:00:00'. If I want to know whether the event has occurred or not, regardless of the current session time zone setting I can compare the start time with NOW(). Of course, for displaying in a meaningful way to a perspective customer, I would need to set the correct session time zone. If I did not need to do time comparisons, then I would probably be better off just using a DATETIME column, which will display correctly (with an implied EST time zone) regardless of what the current session time zone is.
TIMESTAMP LIMITATION
The TIMESTAMP
type has a range of '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC and so it may not usable for your particular application. In that case you will have to use a DATETIME
type. You will, of course, always have to be concerned that the current session time zone is set properly whenever you are using this type with date functions such as NOW()
.
To complement Jon Lin's answer, here is a no-trailing-slash technique that also works if the website is located in a directory (like example.org/blog/):
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [R=301,L]
For the sake of completeness, here is an alternative emphasizing that REQUEST_URI
starts with a slash (at least in .htaccess
files):
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} /(.*)/$
RewriteRule ^ /%1 [R=301,L] <-- added slash here too, don't forget it
Just don't use %{REQUEST_URI} (.*)/$
. Because in the root directory REQUEST_URI
equals /
, the leading slash, and it would be misinterpreted as a trailing slash.

Complementing @Bob Jarvis and @dmikam answer, Postgres don't perform a good plan when you don't use LATERAL, below a simulation, in both cases the query data results are the same, but the cost are very different
Table structure
CREATE TABLE ITEMS (
N INTEGER NOT NULL,
S TEXT NOT NULL

INSERT INTO ITEMS
SELECT

My Postgres version is PostgreSQL 10.3 (Debian 10.3-1.pgdg90+1)
You can also declare class variables as None which will prevent propagation. This is useful when you need a well defined class and want to prevent AttributeErrors. For example:
>>> class TestClass(object):
... t = None
...
>>> test = TestClass()
>>> test.t
>>> test2 = TestClass()
>>> test.t = 'test'
>>> test.t
'test'
>>> test2.t
>>>
Also if you need defaults:
>>> class TestClassDefaults(object):
... t = None
... def __init__(self, t=None):
... self.t = t
...
>>> test = TestClassDefaults()
>>> test.t
>>> test2 = TestClassDefaults([])
>>> test2.t
[]
>>> test.t
>>>
Of course still follow the info in the other answers about using mutable vs immutable types as the default in __init__
.
Earlier versions of Java you can try.
public static String daysBetween(Date createdDate, Date expiryDate) {
Calendar createdDateCal = Calendar.getInstance();
createdDateCal.clear();
createdDateCal.setTime(createdDate);
Calendar expiryDateCal = Calendar.getInstance();
expiryDateCal.clear();
expiryDateCal.setTime(expiryDate);
long daysBetween = 0;
while (createdDateCal.before(expiryDateCal)) {
createdDateCal.add(Calendar.DAY_OF_MONTH, 1);
daysBetween++;
}
return daysBetween+"";
}
I actually prefer to use the html button form element and make it runat=server. The button element can hold other elements inside it. You can even add formatting inside it with span's or strong's. Here is an example:
<button id="BtnSave" runat="server"><img src="Images/save.png" />Save</button>
I'm using the following configuration:

You don't need to add --resource flag just type the following and laravel will create the whole desired resources
php artisan make:controller TodoController --model=todo
I encountered the same problem when I tried to install curl in my 32 bit win 7 machine. As answered by Buravchik it is indeed dependency of SSL and installing openssl fixed it. Just a point to take care is that while installing openssl you will get a prompt to ask where do you wish to put the dependent DLLS. Make sure to put it in windows system directory as other programs like curl and wget will also be needing it.
Here is the tutorial to install GBD.
Usually GNU Debugger might not be in your computer, so you would install it first. The installation steps are basic "configure", "make", and "make install".
Once installed, try which gdb
in terminal, to find the executable path of GDB.
Another way is to use reflection:

Try passing width=200
as additional paramater when creating the Label.
This should work in creating label with specified width.
If you want to change it later, you can use:
label.config(width=200)
As you want to change the size of font itself you can try:
label.config(font=("Courier", 44))
/^[\s]*$/
matches empty strings and strings containing whitespaces only
I found the answer here: Is it possible to pass query parameters via Django's {% url %} template tag?
Simply add them to the end:
<a href="{% url myview %}?office=foobar">
For Django 1.5+
<a href="{% url 'myview' %}?office=foobar">
[there is nothing else to improve but I'm getting a stupid error when I fix the code ticks]
String.Trim()
returns a string which equals the input string with all white-spaces trimmed from start and end:
" A String ".Trim() -> "A String"
String.TrimStart()
returns a string with white-spaces trimmed from the start:
" A String ".TrimStart() -> "A String "
String.TrimEnd()
returns a string with white-spaces trimmed from the end:
" A String ".TrimEnd() -> " A String"
None of the methods modify the original string object.
(In some implementations at least, if there are no white-spaces to be trimmed, you get back the same string object you started with:
csharp> string a = "a";
csharp> string trimmed = a.Trim();
csharp> (object) a == (object) trimmed;
returns true
I don't know whether this is guaranteed by the language.)
Try ALT+SHIFT+UP/DOWN
It worked for me!
Don't forget to generate a second password for your Gmail account. You will use this new password in your code. Read this:
https://support.google.com/accounts/answer/185833
Under the section "How to generate an App password" click on "App passwords", then under "Select app" choose "Mail", select your device and click "Generate". Your second password will be printed on the screen.
Select * from people p, address a where p.id = a.person_id and a.zip='97229';
Or you must TRY using JOIN
which is a more efficient and better way to do this as Gordon Linoff in the comments below also says that you need to learn this.
SELECT p.*, a.street, a.city FROM persons AS p
JOIN address AS a ON p.id = a.person_id
WHERE a.zip = '97299';
Here p.*
means it will show all the columns of PERSONS table.
On OSX edit file:

I used the http://www.javadecompilers.com but in some classes it gives you the message "could not load this classes..."
INSTEAD download Android Studio, navigate to the folder containing the java class file and double click it. The code will show in the right pane and I guess you can copy it an save it as a java file from there
You can use the following command to:
ps -ef | grep -i myprocess | awk {'print $2'} | xargs kill -9
or
ps -aux | grep -i myprocess | awk {'print $2'} | xargs kill -9
It works for me.
I think the XML format can be so diverse that it's impossible to write a code that could do this without a very strict defined XML format. Here is what I mean:
<persons>
<person>
<name>Koen Bok</name>
<age>26</age>
</person>
<person>
<name>Plutor Heidepeen</name>
<age>33</age>
</person>
</persons>
Would become
{'persons': [
{'name': 'Koen Bok', 'age': 26},
{'name': 'Plutor Heidepeen', 'age': 33}]
}
But what would this be:
<persons>
<person name="Koen Bok">
<locations name="defaults">
<location long=123 lat=384 />
</locations>
</person>
</persons>
See what I mean?
Edit: just found this article: http://www.xml.com/pub/a/2006/05/31/converting-between-xml-and-json.html
You must use
list.remove(indexYouWantToReplace);
first.
Your elements will become like this. [zero, one, three]
then add this
list.add(indexYouWantedToReplace, newElement)
Your elements will become like this. [zero, one, new, three]
<h1><span>This is</span> a Headline</h1>
h1 { font-weight: normal; text-transform: uppercase; }
h1 span { font-weight: bold; }
I'm not sure if it was just for the sake of showing us, but as a side note, you should always set uppercase text with CSS :)
If you want to just fit the image in image view you can use" wrap content" in height and width property with scale-type but if you want to set manually you have to use LayoutParams.
Layoutparams is efficient for setting the layout height and width programmatically.
Now it works ok from CodeIgniter 2.1.0
//By default CodeIgniter enables access to the $_GET array. If for some

$config['allow_get_array'] = TRUE;
I read about an experiment here: http://webreflection.blogspot.com/2010/12/100-client-side-image-resizing.html
The theory is that you can use canvas to resize the images on the client before uploading. The prototype example seems to work only in recent browsers, interesting idea though...
However, I’m not sure about using canvas to compress images, but you can certainly resize them.
Inspired by Steve, and as the updates for Java 11. Here's how we did the BigDecimal reformatting to avoid scientific notation.
public class PriceSerializer extends JsonSerializer<BigDecimal> {
@Override
public void serialize(BigDecimal value, JsonGenerator jgen, SerializerProvider provider) throws IOException {
// Using writNumber and removing toString make sure the output is number but not String.
jgen.writeNumber(value.setScale(2, RoundingMode.HALF_UP));
}
}
I have tried your code and it works just fine. The file is being created without any problem, this is the code I used (it's your code, I just changed the datasource for testing):
public ActionResult ExportToExcel()
{
var products = new System.Data.DataTable("teste");
products.Columns.Add("col1", typeof(int));
products.Columns.Add("col2", typeof(string));
products.Rows.Add(1, "product 1");
products.Rows.Add(2, "product 2");
products.Rows.Add(3, "product 3");
products.Rows.Add(4, "product 4");
products.Rows.Add(5, "product 5");
products.Rows.Add(6, "product 6");
products.Rows.Add(7, "product 7");
var grid = new GridView();
grid.DataSource = products;
grid.DataBind();
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls");
Response.ContentType = "application/ms-excel";
Response.Charset = "";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
grid.RenderControl(htw);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
return View("MyView");
}
This is what I used on MAC.
Use your preferred compiler.
Compile with gcc.
gcc -lstdc++ filename.cpp -o outputName
Or Compile with clang.
clang++ filename.cpp -o outputName
After done compiling. You can run it with.
./outputFile
This's my take on this, it's in Kotlin but can be converted to Java with little effort:
val percentageRegex = Regex("""(?<!\\)%""")
val underscoreRegex = Regex("""(?<!\\)_""")
infix fun String.like(predicate: String): Boolean {
//Split the text by every % not preceded by a slash.
//We transform each slice before joining them with .* as a separator.
return predicate.split(percentageRegex).joinToString(".*") { percentageSlice ->
//Split the text by every _ not preceded by a slash.
//We transform each slice before joining them with . as a separator.
percentageSlice.split(underscoreRegex).joinToString(".") { underscoreSlice ->
//Each slice is wrapped in "Regex quotes" to ignore all
// the metacharacters they contain.
//We also remove the slashes from the escape sequences
// since they are now treated literally.
Pattern.quote(
underscoreSlice.replace("\\_", "_").replace("\\%", "%")
)
}
}.let { "^$it$" }.toRegex().matches(this@like)
}
It might not be the most performant of all the solutions here, but it's probably the most accurate.
It ignores all the other Regex metacharacters other than % and _ and also supports escaping them with a slash.
find . -type f -name '*php' -o -name '*js' -o -name '*html' |\
xargs grep -liE 'document\.cookie|setcookie'
fmt.Println("%+v", structure variable)
A better way to do this would be to create a global constant for the string "%+v" in a package called "commons"(maybe) and use it everywhere in your code
//In commons package
const STRUCTURE_DATA_FMT = "%+v"
//In your code everywhere
fmt.Println(commons.STRUCTURE_DATA_FMT, structure variable)

This is a quite confusing way of using Apache configuration directives.
Technically, the first bit is equivalent to
Allow From All
This is because Order Deny,Allow
makes the Deny directive evaluated before the Allow Directives.
In this case, Deny and Allow conflict with each other, but Allow, being the last evaluated will match any user, and access will be granted.
Now, just to make things clear, this kind of configuration is BAD and should be avoided at all cost, because it borders undefined behaviour.
The Limit sections define which HTTP methods have access to the directory containing the .htaccess file.
Here, GET and POST methods are allowed access, and PUT and DELETE methods are denied access. Here's a link explaining what the various HTTP methods are: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
However, it's more than often useless to use these limitations as long as you don't have custom CGI scripts or Apache modules that directly handle the non-standard methods (PUT and DELETE), since by default, Apache does not handle them at all.
It must also be noted that a few other methods exist that can also be handled by Limit, namely CONNECT, OPTIONS, PATCH, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
The last bit is also most certainly useless, since any correctly configured Apache installation contains the following piece of configuration (for Apache 2.2 and earlier):
#
# The following lines prevent .htaccess and .htpasswd files from being
# viewed by Web clients.
#
<Files ~ "^\.ht">
Order allow,deny
Deny from all
Satisfy all
</Files>
which forbids access to any file beginning by ".ht".
The equivalent Apache 2.4 configuration should look like:
<Files ~ "^\.ht">
Require all denied
</Files>
The issue because of not loading jquery ui library.

Call above path in your file.
There are already a bunch of great answers here that use Newtonsoft.JSON, but here's one more that uses JObject.Parse
in combination with ToString()
, since that hasn't been mentioned yet:
var jObj = Newtonsoft.Json.Linq.JObject.Parse(json);
var formatted = jObj.ToString(Newtonsoft.Json.Formatting.Indented);
For example, like this:
const querystring = require('querystring');
const https = require('https');
var postData = querystring.stringify({
'msg' : 'Hello World!'
});
var options = {
hostname: 'posttestserver.com',
port: 443,
path: '/post.php',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': postData.length
}
};
var req = https.request(options, (res) => {
console.log('statusCode:', res.statusCode);
console.log('headers:', res.headers);
res.on('data', (d) => {
process.stdout.write(d);
});
});
req.on('error', (e) => {
console.error(e);
});
req.write(postData);
req.end();
you could check the files
/proc/[pid]/task/[thread ids]/status
The best thing is to actually use the kernel makefile to install the module:
Here is are snippets to add to your Makefile
around the top add:
PWD=$(shell pwd)
VER=$(shell uname -r)
KERNEL_BUILD=/lib/modules/$(VER)/build
# Later if you want to package the module binary you can provide an INSTALL_ROOT
# INSTALL_ROOT=/tmp/install-root
around the end add:
install:
$(MAKE) -C $(KERNEL_BUILD) M=$(PWD) \
INSTALL_MOD_PATH=$(INSTALL_ROOT) modules_install
and then you can issue
sudo make install
this will put it either in /lib/modules/$(uname -r)/extra/
or /lib/modules/$(uname -r)/misc/
and run depmod appropriately
Swift is not like languages like JavaScript, where you can call a function without passing the parameters and it will still be called. So to call a function in Swift, you need to assign a value to its parameters.
Default values for parameters allow you to assign a value without specifying it when calling the function. That's why test()
works when you specify a default value on test's declaration.
If you don't include that default value, you need to provide the value on the call: test(nil)
.
Also, and not directly related to this question, but probably worth to note, you are using the "C++" way of dealing with possibly null pointers, for dealing with possible nil optionals in Swift. The following code is safer (specially in multithreading software), and it allows you to avoid the forced unwrapping of the optional:
func test(firstThing: Int? = nil) {
if let firstThing = firstThing {
print(firstThing)
}
print("done")
}
test()
VirtualBox for Windows
Resizing your disk file while preserving your virtual machine settings!
Start cmd.exe
cd
to Oracle VM VirtualBox's dir (on 64-bit systems: "C:\Program Files\Oracle\VirtualBox\"
)
Run these commands (as above):
VBoxManage clonehd "C:\path\to\source.vmdk" "C:\path_to\cloned.vdi" --format vdi
VBoxManage modifyhd "C:\path\to\cloned.vdi" --resize 51200
Windows explorer and "copy address as text" via the address bar should help you get the path you need.
On windows system, The VirtaulBox VM directory underneath your user may contain an XML formatted database file of settings you've configured for your VM. Rename this file, with a .bak
extension (it has a .vbox
extension). Rename the original .vmdk
file with a .bak
extension as well to avoid another error. You can now safetly perform the third step without the error message to convert the machine back to .vmdk
format, or the "duplicate disk" error.
VBoxManage clonehd "C:\path_to\cloned.vdi" "C:\path_to\source.vmdk" --format vmdk
You will be presented with a UID token. Copy this token by drag-highlighting it from the Windows Command Interpetor window and using the Ctrl+C
keyboard shortcut.
Open the .vbox.bak
file in a text editor such as Notepad++. You'll be presented with an XML-like database file. Look for these lines:
<VirtualBox xmlns="http://www.virtualbox.org/" version="1.16-windows">
<Machine uuid="{some uid}" name="source disk name" OSType="the_vbox_OS" snapshotFolder="Snapshots" lastStateChange="2043-03-23T00:54:18Z">
<MediaRegistry>
<HardDisks>
<HardDisk uuid="{some uid}" location="C:\path_to\source.vmdk" ...
On the line <HardDisk uuid="{some uid}" location="C:\path_to\source.vmdk" ...
, delete the old UID token between the brackets and paste the one you copied from the command window. Make sure that you leave the brackets in place!
Save this file, and exit your text editor. Rename the .vbox.bak
file to give it back its expected extension of .vbox
.
It is now safe to remove the .bak
files remaining in the directory. What remains is a resized .vmdk
with an updated .vbox
database while with your previously preserved VirtualBox Manager settings.
You can now start the VirtualBox VM Manager and execute your VM, using the appropriate tools for the operating system to fill the new free space.
For Windows VMs, use diskpart
from the command prompt booted from the Windows Recovery Consule (recovery partition) to SELECT DISK 1
, LIST PARTITION
and gather the partition number of your C:\
drive, then SELECT PARTITION #
. You can use the EXTEND SIZE=mb
to resize the Windows C:\ drive to the appropriate value. Make sure you leave room for the recovery and boot partitions! It's safe to subtract 4096 MB from your new virtual disk size to get this value, because of shadow copy and windows recovery files.
For Linux VMs, a live .ISO
of gparted you can boot with the VM's disk file can be found at: http://gparted.org/ It will get you straight into a graphical user interface-based gparted-gtk, from where you can fill your free space.
For PPC / Mac VMs, Disk Utility
from the Finder will asisst you in filling the free space, but you may want to consider the gparted Linux option, as currently the only method of which to boot MacOSX in VirtualBox is hackintosh, and you cannot extend your volume while booted into MacOSX. You may also want to seek out tweaking the VM's settings temporarily for gparted
, to get it to boot. MacOSX partitions are recognized by gparted as HFS
- "Heaping File System" partitions.
Because the internet. ;) You're finished. Enjoy your new resized virtual .vmdk
disk image with VirtualBox for Windows!
Always check manually the methods, tags you use, and make sure that they always escape (once) in the end. Frameworks have many bugs and differences in this aspect.
An overview: http://www.gablog.eu/online/node/91
Does the screenshot contain only the icon? If so, the L2 distance of the two images might suffice. If the L2 distance doesn't work, the next step is to try something simple and well established, like: Lucas-Kanade. Which I'm sure is available in OpenCV.
For those who are still stuck...
Using NetBeans 8.1 and GlassFish 4.1 with CDI, for some reason I had this issue only locally, not on the remote server. What did the trick:
-> using javaee-web-api 7.0 instead of the default pom version provided by NetBeans, which is javaee-web-api 6.0, so:
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
<type>jar</type>
</dependency>
-> upload this javaee-web-api-7.0.jar as a lib to on the server (lib folder in the domain1 folder) and restart the server.
I didn't know the existing sa password so this is what I did:
Open Services in Control Panel
Find the "SQL Server (SQLEXPRESS)" entry and select properties
Stop the service
Enter "-m" at the beginning of the "Start parameters" fields. If there are other parameters there already add a semi-colon after -m;
Start the service
Open a Command Prompt
Enter the command:
osql -S YourPcName\SQLEXPRESS -E
(change YourPcName to whatever your PC is called).
alter login sa enable go sp_password NULL,'new_password','sa' go quit
Stop the "SQL Server (SQLEXPRESS)" service
Remove the "-m" from the Start parameters field
Start the service
I think that you want the file's parent to be on the classpath, not the actual file itself.
Try this (may need some tweaking):
String path = "c:/temp/mybundle.txt";
java.io.File fl = new java.io.File(path);
try {
resourceURL = fl.getParentFile().toURL();
} catch (MalformedURLException e) {
e.printStackTrace();
}
URLClassLoader urlLoader = new URLClassLoader(new java.net.URL[]{resourceURL});
java.util.ResourceBundle bundle = java.util.ResourceBundle.getBundle("mybundle.txt",
java.util.Locale.getDefault(), urlLoader );
// find the first select and bind a click handler
$('#column_select').bind('click', function(){
// retrieve the selected value
var value = $(this).val(),
// build a regular expression that does a head-match
expression = new RegExp('^' + value),
// find the second select
$select = $('#layout_select);
// hide all children (<option>s) of the second select,
// check each element's value agains the regular expression built from the first select's value
// show elements that match the expression
$select.children().hide().filter(function(){
return !!$(this).val().match(expression);
}).show();
});
(this is far from perfect, but should get you there…)
Here is the simplest example that has the key lines of code:
import numpy as np
import matplotlib.pyplot as plt
H = np.array([[1, 2, 3, 4],
[5, 6, 7, 8],
[9, 10, 11, 12],
[13, 14, 15, 16]])
plt.imshow(H, interpolation='none')
plt.show()
From arrays
An array is a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created. After creation, its length is fixed. You've seen an example of arrays already, in the main method of the "Hello World!" application. This section discusses arrays in greater detail.
So in the case of a String array, once you create it with some length, you can't modify it, but you can add elements until you fill it.
String[] arr = new String[10]; // 10 is the length of the array.
arr[0] = "kk";
arr[1] = "pp";
...
So if your requirement is to add many objects, it's recommended that you use Lists like:
List<String> a = new ArrayList<String>();
a.add("kk");
a.add("pp");
Add this before calling curl_exec($curl_handle)
curl_setopt($curl_handle, CURLOPT_CUSTOMREQUEST, 'GET');
You can register another directive on top of ng-click
which amends the default behaviour of ng-click
and stops the event propagation. This way you wouldn't have to add $event.stopPropagation
by hand.
app.directive('ngClick', function() {
return {
restrict: 'A',
compile: function($element, attr) {
return function(scope, element, attr) {
element.on('click', function(event) {
event.stopPropagation();
});
};
}
}
});
git add -u
git reset -- main/dontcheckmein.txt
I just fixed this issue after struggling for a few days. Here's what worked for me:
First, check your Apache error_log
file and look at the most recent error message.
If it says something like:
access to /mySite denied (filesystem path
'/Users/myusername/Sites/mySite') because search permissions
are missing on a component of the path
then there is a problem with your file permissions. You can fix them by running these commands from the terminal:
$ cd /Users/myusername/Sites/mySite
$ find . -type f -exec chmod 644 {} \;
$ find . -type d -exec chmod 755 {} \;
Then, refresh the URL where your website should be (such as http://localhost/mySite
).
If you're still getting a 403 error, and if your Apache error_log
still says the same thing, then progressively move up your directory tree, adjusting the directory permissions as you go. You can do this from the terminal by:
$ cd ..
$ chmod 755 mySite
If necessary, continue with:
$ cd ..
$ chmod Sites
and, if necessary,
$ cd ..
$ chmod myusername
DO NOT go up farther than that. You could royally mess up your system.
If you still get the error that says search permissions are missing on a component of the path
, I don't know what you should do. However, I encountered a different error (the one below) which I fixed as follows:
If your error_log
says something like:
client denied by server configuration:
/Users/myusername/Sites/mySite
then your problem is not with your file permissions, but instead with your Apache configuration.
Notice that in your httpd.conf
file, you will see a default configuration like this (Apache 2.4+):
<Directory />
AllowOverride none
Require all denied
</Directory>
or like this (Apache 2.2):
<Directory />
Order deny,allow
Deny from all
</Directory>
DO NOT change this! We will not override these permissions globally, but instead in your httpd-vhosts.conf
file.
First, however, make sure that your vhost Include
line in httpd.conf
is uncommented. It should look like this. (Your exact path may be different.)
# Virtual hosts
Include etc/extra/httpd-vhosts.conf
Now, open the httpd-vhosts.conf
file that you just Include
d. Add an entry for your webpage if you don't already have one. It should look something like this. The DocumentRoot
and Directory
paths should be identical, and should point to wherever your index.html
or index.php
file is located. For me, that's within the public
subdirectory.
For Apache 2.2:
<VirtualHost *:80>
# ServerAdmin [email protected]
DocumentRoot "/Users/myusername/Sites/mySite/public"
ServerName mysite
# ErrorLog "logs/dummy-host2.example.com-error_log"
# CustomLog "logs/dummy-host2.example.com-access_log" common
<Directory "/Users/myusername/Sites/mySite/public">
Options Indexes FollowSymLinks Includes ExecCGI
AllowOverride All
Order allow,deny
Allow from all
Require all granted
</Directory>
</VirtualHost>
The lines saying
AllowOverride All
Require all granted
are critical for Apache 2.4+. Without these, you will not be overriding the default Apache settings specified in httpd.conf
. Note that if you are using Apache 2.2, these lines should instead say
Order allow,deny
Allow from all
This change has been a major source of confusion for googlers of this problem, such as I, because copy-pasting these Apache 2.2 lines will not work in Apache 2.4+, and the Apache 2.2 lines are still commonly found on older help threads.
Once you have saved your changes, restart Apache. The command for this will depend on your OS and installation, so google that separately if you need help with it.
I hope this helps someone else!
PS: If you are having trouble finding these .conf
files, try running the find
command, such as:
$ find / -name httpd.conf
157/32 is int/int
, which results in an int
.
Try using the double literal - 157/32d
, which is int/double
, which results in a double
.
You need to invoke CreateInstanceAndUnwrap
before your proxy object will execute in the foreign application domain.
class Program
{
static void Main(string[] args)
{
AppDomainSetup domaininfo = new AppDomainSetup();
domaininfo.ApplicationBase = System.Environment.CurrentDirectory;
Evidence adevidence = AppDomain.CurrentDomain.Evidence;
AppDomain domain = AppDomain.CreateDomain("MyDomain", adevidence, domaininfo);
Type type = typeof(Proxy);
var value = (Proxy)domain.CreateInstanceAndUnwrap(
type.Assembly.FullName,
type.FullName);
var assembly = value.GetAssembly(args[0]);
// AppDomain.Unload(domain);
}
}
public class Proxy : MarshalByRefObject
{
public Assembly GetAssembly(string assemblyPath)
{
try
{
return Assembly.LoadFile(assemblyPath);
}
catch (Exception)
{
return null;
// throw new InvalidOperationException(ex);
}
}
}
Also, note that if you use LoadFrom
you'll likely get a FileNotFound
exception because the Assembly resolver will attempt to find the assembly you're loading in the GAC or the current application's bin folder. Use LoadFile
to load an arbitrary assembly file instead--but note that if you do this you'll need to load any dependencies yourself.
It could be related to log4j.
Do you have log4j.jar file in the websphere java classpath (as defined in the startup file) as well as the application classpath ?
If you do make sure that the log4j.jar file is in the java classpath and that it is NOT in the web-inf/lib directory of your webapp.
It can also be related with the ant version (may be not your case, but I do put it here for reference):
You have a .class file in your class path (i.e. not a directory or a .jar file). Starting with ant 1.6, ant will open the files in the classpath checking for manifest entries. This attempted opening will fail with the error "java.util.zip.ZipException"
The problem does not exist with ant 1.5 as it does not try to open the files. - so make sure that your classpath's do not contain .class files.
On a side note, did you consider having separate jars ?
You could in the manifest of your main jar, refer to the other jars with this attribute:
Class-Path: one.jar two.jar three.jar
Then, place all of your jars in the same folder.
Again, may be not valid for your case, but still there for reference.
The selected solution is fine if you want jQuery to process all svg elements in your DOM and your DOM is of reasonable size. But if your DOM is large and you decide to load parts of your DOM dynamically, it really makes no sense to have to rescan the entire DOM just to update svg elements. Instead, use a jQuery plugin to do this:
/**
* A jQuery plugin that loads an svg file and replaces the jQuery object with its contents.
*
* The path to the svg file is specified in the src attribute (which normally does not exist for an svg element).
*

(function ($) {
$.fn.svgLoader = function () {
var src = $(this).attr("src");
var width = this.attr("width");
var height = this.attr("height");
var cls = this.attr("class");
var ctx = $(this);
// Get the svg file and replace the <svg> element.
$.ajax({

In your html, specify an svg element as follows:
<svg src="images/someSvgFile.svg" height="45" width="45" class="mySVGClass"/>
And apply the plugin:
$(".mySVGClass").svgLoader();
You can also use the Filter button to filter tables with a certain string in it. You can do the same with stored procedures and views.
That is because you are trying to access the plugin before it's loaded. You should try making a call to it when the DOM is loaded by surrounding it with this:
$(document).ready(function(){
$("#colorpicker").colorpicker();
}
Btw you can also use the ui-sref attribute in your templates to pass objects
ui-sref="myState({ myParam: myObject })"
Use:
/category[@name='Sport' and author/text()[1]='James Small']
or use:
/category[@name='Sport' and author[starts-with(.,'James Small')]]
It is a good rule to try to avoid using the //
pseudo-operator whenever possible, because its evaluation can typically be very slow.
Also:
./somename
is equivalent to:
somename
so it is recommended to use the latter.
They are actually strings, not numbers. The easiest way to produce a number from a string is to prepend it with +
:
var x = +y + +z;
Edit: doesnt work yet...
Add this to your JS:
var src = fetch('https://page.com')
It saves the source of page.com to variable 'src'
I've got a similar error when installing FCL that needs CCD lib(libccd) like this:
/usr/bin/ld: /usr/local/lib/libccd.a(ccd.o): relocation R_X86_64_32S against `a local symbol' can not be used when making a shared object; recompile with -fPIC
I find that there is two different files named "libccd.a" :
I solved the problem by removing the first file.
git diff <local branch> <remote>/<remote branch>
For example git diff main origin/main
, or git diff featureA origin/next
Of course to have said remote-tracking branch you need to git fetch
first; and you need it to have up to date information about branches in remote repository.
Use position: relative on the parent element.
Also note that had you not added any position attributes to any of the divs you wouldn't have seen this behavior. Juan explains further.
If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:
The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.
For editing Excel files from within a C# application, I recently started using NPOI. I'm very satisfied with it.
Follow the below steps:
If you don't find your WWDR certificate in Login or System tab, then select category "All items" on the left side. Most probably you will get to see an expired WWDR certificate here, and you can remove it. An expired certificate is always shown with a red asterisk.
You can also try: (I tried this and it worked for me)
SELECT ISNULL((SELECT SUM(columnA) FROM my_table WHERE columnB = 1),0)) INTO res;
The difference between absolute and relative imports come into play only when you import a module from a package and that module imports an other submodule from that package. See the difference:
$ mkdir pkg
$ touch pkg/__init__.py
$ touch pkg/string.py
$ echo 'import string;print(string.ascii_uppercase)' > pkg/main1.py
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main1
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pkg/main1.py", line 1, in <module>
import string;print(string.ascii_uppercase)
AttributeError: 'module' object has no attribute 'ascii_uppercase'
>>>
$ echo 'from __future__ import absolute_import;import string;print(string.ascii_uppercase)' > pkg/main2.py
$ python2

In particular:
$ python2 pkg/main2.py
Traceback (most recent call last):

$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ
>>>
$ python2 -m pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ
Note that python2 pkg/main2.py
has a different behaviour then launching python2
and then importing pkg.main2
(which is equivalent to using the -m
switch).
If you ever want to run a submodule of a package always use the -m
switch which prevents the interpreter for chaining the sys.path
list and correctly handles the semantics of the submodule.
Also, I much prefer using explicit relative imports for package submodules since they provide more semantics and better error messages in case of failure.
This sort of protection is normally provided by using HTTPS, so that all communication between the web server and the client is encrypted.
The exact instructions on how to achieve this will depend on your web server.
The Apache documentation has a SSL Configuration HOW-TO guide that may be of some help. (thanks to user G. Qyy for the link)

private setters are same as read-only fields. They can only be set in constructor. If you try to set from outside you get compile time error.
public class MyClass
{
public MyClass()
{
// Set the private property.
this.Name = "Sample Name from Inside";
}
public MyClass(string name)
{
// Set the private property.
this.Name = name;
}
string _name;
public string Name
{
get
{
return this._name;
}
private set
{
// Can only be called in this class.
this._name = value;
}
}
}
class Program
{
static void Main()
{
MyClass mc = new MyClass();
Console.WriteLine(mc.name);
MyClass mc2 = new MyClass("Sample Name from Outside");
Console.WriteLine(mc2.name);
}
}
Please see below screen shot when I tried to set it from outside of the class.
I had a similar problem. The catalina.out logged this log Message

I know this may be obvious for most people who use RegEx frequently, but in case any readers are new to RegEx, I thought I should point out an observation I made that was helpful for one of my projects.
In a previous answer from @kennytm:
^\d{5}(?:[-\s]\d{4})?$
…? = The pattern before it is optional (for condition 1)
If you want to allow both standard 5 digit and +4 zip codes, this is a great example.
To match only zip codes in the US 'Zip + 4' format as I needed to do (conditions 2 and 3 only), simply remove the last ?
so it will always match the last 5 character group.
A useful tool I recommend for tinkering with RegEx is linked below:
I use this tool frequently when I find RegEx that does something similar to what I need, but could be tailored a bit better. It also has a nifty RegEx reference menu and informative interface that keeps you aware of how your changes impact the matches for the sample text you entered.
If I got anything wrong or missed an important piece of information, please correct me.
If I understand your question correctly, then you probably want a density estimate along with the histogram:
X <- c(rep(65, times=5), rep(25, times=5), rep(35, times=10), rep(45, times=4))
hist(X, prob=TRUE) # prob=TRUE for probabilities not counts
lines(density(X)) # add a density estimate with defaults
lines(density(X, adjust=2), lty="dotted") # add another "smoother" density
Edit a long while later:
Here is a slightly more dressed-up version:
X <- c(rep(65, times=5), rep(25, times=5), rep(35, times=10), rep(45, times=4))
hist(X, prob=TRUE, col="grey")# prob=TRUE for probabilities not counts
lines(density(X), col="blue", lwd=2) # add a density estimate with defaults
lines(density(X, adjust=2), lty="dotted", col="darkgreen", lwd=2)

Alternatively you could update brew
by installing it again. (Think I did this as El Capitan changed something)
Note: this is a heavy handed approach that will remove all applications installed via brew!
Try to install brew a fresh and it will tell how to uninstall.
At original time of writing to uninstall:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
Edit: As of 2020 to uninstall:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"
Finally got the solution here - https://stackoverflow.com/a/49663101/9640177
implementation files('libs/aar-file.aar')
Edit I had one more complication - I had set minifyEnabled true for the library module.
Use the type()
builtin function:
>>> i = 123
>>> type(i)
<type 'int'>
>>> type(i) is int
True
>>> i = 123.456
>>> type(i)
<type 'float'>
>>> type(i) is float
True
To check if a variable is of a given type, use isinstance
:
>>> i = 123
>>> isinstance(i, int)
True
>>> isinstance(i, (float, str, set, dict))
False
Note that Python doesn't have the same types as C/C++, which appears to be your question.

For java after 1.7
List<String> lines = Files.readAllLines(Paths.get(getClass().getResource("test.csv").toURI()));
I can suggest you a simpler way,
Call this method if the view controller's status bar attributes, such as hidden/unhidden status or style, change. If you call this method within an animation block, the changes are animated along with the rest of the animation block.
It worked for me in iOS 10.1.
Objective C
[self setNeedsStatusBarAppearanceUpdate];
-(UIStatusBarStyle)preferredStatusBarStyle {
return UIStatusBarStyleLightContent;
}
Swift
setNeedsStatusBarAppearanceUpdate()
var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
I am surprised nobody pointed this out. Anyway enjoy :)
Strings are a great example of uses of double pointers. The string itself is a pointer, so any time you need to point to a string, you'll need a double pointer.
Preferable way for windows:
Open the console and start the interactive MySQL mode
use <name_of_your_database>;
source <path_of_your_.sql>
All the random methods end up calling random.random()
so the best way is to call it directly:
[int(1000*random.random()) for i in xrange(10000)]
For example,
random.randint
calls random.randrange
.random.randrange
has a bunch of overhead to check the range before returning istart + istep*int(self.random() * n)
.NumPy is much faster still of course.

In JavaScript, you cannot pass variables by reference to a function. However you can pass an object by reference.
ODATA is a special kind of REST where we can query data uniformly from URL.
Another shorthand to (@maudulus's answer) to remove {maxFractionDigits}
since it's optional.
You can use {{numberExample | number : '1.2'}}
you cant do it.. because jsp is compiled and converted into html server side whereas javascript is executed on client side. you may set the value to a hidden html element and send to servlet in request just in case you want to use for further

tv.setText(String.valueOf(s.toString().length()));
}
public void beforeTextChanged(CharSequence s, int start, int count, int after){}
public void onTextChanged(CharSequence s, int start, int before, int count){}
});
If you wanted to change the title from a child view controller of a Page View Controller that's embedded in a navigation controller, it would look like this:
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
self.parent?.title = "some title"
}

In my case, VS 2019 on Windows 10 x64,

in Google Chrome and you'll see that it's not secure. Yet!Most windows users won't have that font on their computers. Also, you can't just submit it to your server and call it using font-face because this isn't a free font...
And last, but not least, answering the question that nobody mentioned yet, Helvetica and Helvetica Neue do not render well on screen unless they have a really big font-size
. You'll find a lot of pages using this font, and in all of them you'll see that the top border of a line of text looks wavy and that some letters look taller than others. In my opinion this is the main reason why you shouldn't use it. There are other options for you to use, like Open Sans.
This is expected behavior for an uncaught exception with display_errors off.
Your options here are to turn on display_errors via php or in the ini file or catch and output the exception.
ini_set("display_errors", 1);
or
try{
// code that may throw an exception
} catch(Exception $e){
echo $e->getMessage();
}
If you are throwing exceptions, the intention is that somewhere further down the line something will catch and deal with it. If not it is a server error (500).
Another option for you would be to use set_exception_handler to set a default error handler for your script.
function default_exception_handler(Exception $e){
// show something to the user letting them know we fell down
echo "<h2>Something Bad Happened</h2>";
echo "<p>We fill find the person responsible and have them shot</p>";
// do some logging for the exception and call the kill_programmer function.
}
set_exception_handler("default_exception_handler");
I know this question already has an accepted answer, but for me, a .NET beginner, there was a simple solution to what I was doing wrong and I thought I'd share.
I had been doing this:
@Html.HiddenFor(Model.Foo.Bar.ID)
What worked for me was changing to this:
@Html.HiddenFor(m => m.Foo.Bar.ID)
(where "m" is an arbitrary string to represent the model object)
Although this doesnt answer the question directly about command line, but from Windows OS, use the Windows Explorer ftp://username@server
this will use Passive Mode by default
For command line, active mode is the default

You dont need call addSheet()
method. After creating sheet, it already add to excel. Here i fixed some codes:
//First sheet
$sheet = $objPHPExcel->getActiveSheet();
//Start adding next sheets
$i=0;
while ($i < 10) {
// Add new sheet
$objWorkSheet = $objPHPExcel->createSheet($i); //Setting index when creating
//Write cells
$objWorkSheet->setCellValue('A1', 'Hello'.$i)
->setCellValue('B2', 'world!')
->setCellValue('C1', 'Hello')
->setCellValue('D2', 'world!');
// Rename sheet
$objWorkSheet->setTitle("$i");
$i++;
}
This resolved my problem.
Hope it helps

In C++11, use std::stoi
as:
std::string s = "10";
int i = std::stoi(s);
Note that std::stoi
will throw exception of type std::invalid_argument
if the conversion cannot be performed, or std::out_of_range
if the conversion results in overflow(i.e when the string value is too big for int
type). You can use std::stol
or std:stoll
though in case int
seems too small for the input string.
In C++03/98, any of the following can be used:
std::string s = "10";
int i;
//approach one
std::istringstream(s) >> i; //i is 10 after this
//approach two
sscanf(s.c_str(), "%d", &i); //i is 10 after this
Note that the above two approaches would fail for input s = "10jh"
. They will return 10 instead of notifying error. So the safe and robust approach is to write your own function that parses the input string, and verify each character to check if it is digit or not, and then work accordingly. Here is one robust implemtation (untested though):
int to_int(char const *s)
{
if ( s == NULL || *s == '\0' )
throw std::invalid_argument("null or empty string argument");
bool negate = (s[0] == '-');
if ( *s == '+' || *s == '-' )
++s;
if ( *s == '\0')
throw std::invalid_argument("sign character only.");
int result = 0;
while(*s)
{
if ( *s < '0' || *s > '9' )
throw std::invalid_argument("invalid input string");
result = result * 10 - (*s - '0'); //assume negative number
++s;
}
return negate ? result : -result; //-result is positive!
}
This solution is slightly modified version of my another solution.

Also, another case where it is hard to spot is when you have a file with just a function, I know it is not a common use case but it is annoying and had to spot the error.

In Python, you can use urllib2
(http://docs.python.org/2/library/urllib2.html) to do all of that work for you.
Simply enough:
import urllib2
f = urllib2.urlopen(url)
print f.read()
Will print the received HTTP response.
To pass GET/POST parameters the urllib.urlencode()
function can be used. For more information, you can refer to the Official Urllib2 Tutorial

the most effective method is to use android-async-http
You can use this code to upload a file:
// gather your request parameters
File myFile = new File("/path/to/file.png");
RequestParams params = new RequestParams();
try {
params.put("profile_picture", myFile);
} catch(FileNotFoundException e) {}
// send request
AsyncHttpClient client = new AsyncHttpClient();
client.post(url, params, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] bytes) {
// handle success response
}
@Override
public void onFailure(int statusCode, Header[] headers, byte[] bytes, Throwable throwable) {
// handle failure response
}
});
Note that you can put this code directly into your main Activity, no need to create a background Task explicitly. AsyncHttp will take care of that for you!
Strictly speaking, the difference between Database and Schema is inexisting in MySql.
However, this is not the case in other database engines such as SQL Server. In SQL server:,
Every table belongs to a grouping of objects in the database called database schema. It's a container or namespace (Querying Microsoft SQL Server 2012)
By default, all the tables in SQL Server belong to a default schema called dbo. When you query a table that hasn't been allocated to any particular schema, you can do something like:
SELECT *
FROM your_table
which is equivalent to:
SELECT *
FROM dbo.your_table
Now, SQL server allows the creation of different schema, which gives you the possibility of grouping tables that share a similar purpose. That helps to organize the database.
For example, you can create an schema called sales, with tables such as invoices, creditorders (and any other related with sales), and another schema called lookup, with tables such as countries, currencies, subscriptiontypes (and any other table used as look up table).
The tables that are allocated to a specific domain are displayed in SQL Server Studio Manager with the schema name prepended to the table name (exactly the same as the tables that belong to the default dbo schema).
There are special schemas in SQL Server. To quote the same book:
There are several built-in database schemas, and they can't be dropped or altered:
1) dbo, the default schema.
2) guest contains objects available to a guest user ("guest user" is a special role in SQL Server lingo, with some default and highly restricted permissions). Rarely used.
3) INFORMATION_SCHEMA, used by the Information Schema Views
4) sys, reserved for SQL Server internal use exclusively
Schemas are not only for grouping. It is actually possible to give different permissions for each schema to different users, as described MSDN.
Doing this way, the schema lookup mentioned above could be made available to any standard user in the database (e.g. SELECT
permissions only), whereas a table called supplierbankaccountdetails may be allocated in a different schema called financial, and to give only access to the users in the group accounts
(just an example, you get the idea).
Finally, and quoting the same book again:
It isn't the same Database Schema and Table Schema. The former is the namespace of a table, whereas the latter refers to the table definition
In my case this was caused by an integer overflow. I had a UInt16, and was doubling the value to put into an Int. The faulty code was
let result = Int(myUInt16 * 2)
However, this multiplies as a UInt16, then converts to Int. So if myUInt16 contains a value over 32767 then an overflow occurs.
All was well once I corrected the code to
let result = Int(myUint16) * 2

to a HashSet
effectively removes duplicates, if you need to preserve insertion order, I'd rather suggest you to use this variant
// list is some List of Strings
Set<String> s = new LinkedHashSet<>(list);
Then, if you need to get back a List
reference, you can use again the conversion constructor.
I've created a github repo summing up this article basically: https://medium.com/opinionated-angularjs/techniques-for-authentication-in-angularjs-applications-7bbf0346acec
I'll try to explain as good as possible, hope I help some of you out there:
(1) app.js: Creation of authentication constants on app definition
var loginApp = angular.module('loginApp', ['ui.router', 'ui.bootstrap'])
/*Constants regarding user login defined here*/
.constant('USER_ROLES', {
all : '*',
admin : 'admin',
editor : 'editor',
guest : 'guest'
}).constant('AUTH_EVENTS', {
loginSuccess : 'auth-login-success',
loginFailed : 'auth-login-failed',
logoutSuccess : 'auth-logout-success',
sessionTimeout : 'auth-session-timeout',
notAuthenticated : 'auth-not-authenticated',
notAuthorized : 'auth-not-authorized'
})
(2) Auth Service: All following functions are implemented in auth.js service. The $http service is used to communicate with the server for the authentication procedures. Also contains functions on authorization, that is if the user is allowed to perform a certain action.
angular.module('loginApp')
.factory('Auth', [ '$http', '$rootScope', '$window', 'Session', 'AUTH_EVENTS',
function($http, $rootScope, $window, Session, AUTH_EVENTS) {
authService.login() = [...]
authService.isAuthenticated() = [...]
authService.isAuthorized() = [...]
authService.logout() = [...]
return authService;
} ]);
(3) Session: A singleton to keep user data. The implementation here depends on you.
angular.module('loginApp').service('Session', function($rootScope, USER_ROLES) {
this.create = function(user) {
this.user = user;
this.userRole = user.userRole;
};
this.destroy = function() {
this.user = null;
this.userRole = null;
};
return this;
});
(4) Parent controller: Consider this as the "main" function of your application, all controllers inherit from this controller, and it's the backbone of the authentication of this app.
<body ng-controller="ParentController">
[...]
</body>
(5) Access control: To deny access on certain routes 2 steps have to be implemented:
a) Add data of the roles allowed to access each route, on ui router's $stateProvider service as can be seen below (same can work for ngRoute).
.config(function ($stateProvider, USER_ROLES) {
$stateProvider.state('dashboard', {
url: '/dashboard',
templateUrl: 'dashboard/index.html',
data: {
authorizedRoles: [USER_ROLES.admin, USER_ROLES.editor]
}
});
})
b) On $rootScope.$on('$stateChangeStart') add the function to prevent state change if the user is not authorized.
$rootScope.$on('$stateChangeStart', function (event, next) {
var authorizedRoles = next.data.authorizedRoles;
if (!Auth.isAuthorized(authorizedRoles)) {
event.preventDefault();
if (Auth.isAuthenticated()) {
// user is not allowed
$rootScope.$broadcast(AUTH_EVENTS.notAuthorized);
} else {
// user is not logged in
$rootScope.$broadcast(AUTH_EVENTS.notAuthenticated);
}
}
});
(6) Auth interceptor: This is implemented, but can't be checked on the scope of this code. After each $http request, this interceptor checks the status code, if one of the below is returned, then it broadcasts an event to force the user to log-in again.
angular.module('loginApp')
.factory('AuthInterceptor', [ '$rootScope', '$q', 'Session', 'AUTH_EVENTS',
function($rootScope, $q, Session, AUTH_EVENTS) {
return {
responseError : function(response) {
$rootScope.$broadcast({
401 : AUTH_EVENTS.notAuthenticated,
403 : AUTH_EVENTS.notAuthorized,
419 : AUTH_EVENTS.sessionTimeout,
440 : AUTH_EVENTS.sessionTimeout
}[response.status], response);
return $q.reject(response);
}
};
} ]);
P.S. A bug with the form data autofill as stated on the 1st article can be easily avoided by adding the directive that is included in directives.js.
P.S.2 This code can be easily tweaked by the user, to allow different routes to be seen, or display content that was not meant to be displayed. The logic MUST be implemented server-side, this is just a way to show things properly on your ng-app.
Instead of Creating New Application Pool,You can go to your Existing application Pool->Right click Advance setting->Enable 32-bit Application-----Set to TRUE
Your countLines(String filename)
method throws IOException.
You can't use it in a member declaration. You'll need to perform the operation in a main(String[] args)
method.
Your main(String[] args)
method will get the IOException thrown to it by countLines and it will need to handle or declare it.
Try this to just throw the IOException from main
public class MyClass {
private int lineCount;
public static void main(String[] args) throws IOException {
lineCount = LineCounter.countLines(sFileName);
}
}
or this to handle it and wrap it in an unchecked IllegalArgumentException:
public class MyClass {
private int lineCount;
private String sFileName = "myfile";
public static void main(String[] args) throws IOException {
try {
lineCount = LineCounter.countLines(sFileName);
} catch (IOException e) {
throw new IllegalArgumentException("Unable to load " + sFileName, e);
}
}
}
I like the the answer from Oli (flipping a map), but seems it has a problem: the container map does not allow two elements with the same key.
A solution is to make dst the type multimap. Another one is to dump src into a vector and sort the vector. The former requires minor modifications to Oli's answer, and the latter can be implemented using STL copy concisely
#include <iostream>
#include <utility>
#include <map>
#include <vector>
#include <algorithm>
using namespace std;
int main() {
map<int, int> m;
m[11] = 1;
m[22] = 2;
m[33] = 3;
vector<pair<int, int> > v;
copy(m.begin(),
m.end(),
back_inserter<vector<pair<int, int> > >(v));
for (size_t i = 0; i < v.size(); ++i) {
cout << v[i].first << " , " << v[i].second << "\n";
}
return 0;
};
Most times SDL is in /usr/include/SDL
. If so then your #include <SDL.h>
directive is wrong, it should be #include <SDL/SDL.h>
.
An alternative for that is adding the /usr/include/SDL
directory to your include directories. To do that you should add -I/usr/include/SDL
to the compiler flags...
If you are using an IDE this should be quite easy too...
just like this :
global $wpdb;
$table_name='lorem_ipsum';
$results = $wpdb->get_results("SELECT * FROM $table_name ORDER BY ID DESC LIMIT 1");
print_r($results[0]->id);
simply your selecting all the rows then order them DESC by id , and displaying only the first
You can use substr
:
echo substr('a,b,c,d,e,', 0, -1);
# => 'a,b,c,d,e'
Here's some PowerShell code that should work. You can combine most of this into fewer lines, but I wanted to keep it clear and readable.
[string]$filePath = "C:\tempFile.zip";
[string]$directory = [System.IO.Path]::GetDirectoryName($filePath);
[string]$strippedFileName = [System.IO.Path]::GetFileNameWithoutExtension($filePath);
[string]$extension = [System.IO.Path]::GetExtension($filePath);
[string]$newFileName = $strippedFileName + [DateTime]::Now.ToString("yyyyMMdd-HHmmss") + $extension;
[string]$newFilePath = [System.IO.Path]::Combine($directory, $newFileName);
Move-Item -LiteralPath $filePath -Destination $newFilePath;
This approach is working, but I don't how, can anyone explain, how does it works..
String s = sc.next();
s += sc.nextLine();
I would just raise ValueError, unless you need a more specific exception..
def import_to_orm(name, save=False, recurse=False):
if recurse and not save:
raise ValueError("save must be True if recurse is True")
There's really no point in doing class BadValueError(ValueError):pass
- your custom class is identical in use to ValueError, so why not use that?
Below query is appropriate for the last 30 days records
Here, I have used a review table and review_date
is a column from the review table
SELECT * FROM reviews WHERE DATE(review_date) >= DATE(NOW()) - INTERVAL 30 DAY
Rename your file, commit the changes including the "deleted" file, and don't include the new (renamed) file.
Rename your file back.
I use CDH hadoop and when I export excel report, I have two problems;
1) convert Linux date to excel date,
For that, add an empty column next to date column lets say the top row is B4,
paste below formula and drag the BLACK "+" all the way to your last day at the end of the column. Then hide the original column
=(((B4/1000/60)/60)/24)+DATE(1970|1|1)+(-5/24)
2) Convert disk size from byte to TB, GB, and MB
the best formula for that is this
[>999999999999]# ##0.000,,,," TB";[>999999999]# ##0.000,,," GB";# ##0.000,," MB"
it will give you values with 3 decimals just format cells --> Custom and paste the above code there
git rev-parse --show-toplevel
could be enough if executed within a git repo.
From git rev-parse
man page:
--show-toplevel
Show the absolute path of the top-level directory.
For older versions (before 1.7.x), the other options are listed in "Is there a way to get the git root directory in one command?":
git rev-parse --git-dir
That would give the path of the .git
directory.
The OP mentions:
git rev-parse --show-prefix
which returns the local path under the git repo root. (empty if you are at the git repo root)
Note: for simply checking if one is in a git repo, I find the following command quite expressive:
git rev-parse --is-inside-work-tree
And yes, if you need to check if you are in a .git
git-dir folder:
git rev-parse --is-inside-git-dir
And it works fine, but I am having the concern whether the scripts added to be executed in this manner are being executed asynchronously. If yes then it can happen that work.js runs even before jQuery (or other libraries which I may add in future).
That shouldn't really be a concern: you queue up scripts to be executed in a certain JS context, and that context can't have a race condition as it's single-threaded.
However, the proper way to eliminate this concern is to chain the calls:
chrome.browserAction.onClicked.addListener(function (tab) {
chrome.tabs.executeScript({
file: 'thirdParty/jquery-2.0.3.js'
}, function() {
// Guaranteed to execute only after the previous script returns
chrome.tabs.executeScript({
file: 'work.js'
});
});
});
Or, generalized:
function injectScripts(scripts, callback) {
if(scripts.length) {
var script = scripts.shift();
chrome.tabs.executeScript({file: script}, function() {
if(chrome.runtime.lastError && typeof callback === "function") {
callback(false); // Injection failed
}
injectScripts(scripts, callback);
});
} else {
if(typeof callback === "function") {
callback(true);
}
}
}
injectScripts(["thirdParty/jquery-2.0.3.js", "work.js"], doSomethingElse);
Or, promisified (and brought more in line with the proper signature):
function injectScript(tabId, injectDetails) {
return new Promise((resolve, reject) => {
chrome.tabs.executeScript(tabId, injectDetails, (data) => {
if (chrome.runtime.lastError) {
reject(chrome.runtime.lastError.message);
} else {
resolve(data);
}
});
});
}
injectScript(null, {file: "thirdParty/jquery-2.0.3.js"}).then(
() => injectScript(null, {file: "work.js"})
).then(
() => doSomethingElse
).catch(
(error) => console.error(error)
);
Or, why the heck not, async
/await
-ed for even clearer syntax:
function injectScript(tabId, injectDetails) {
return new Promise((resolve, reject) => {
chrome.tabs.executeScript(tabId, injectDetails, (data) => {
if (chrome.runtime.lastError) {
reject(chrome.runtime.lastError.message);
} else {
resolve(data);
}
});
});
}
try {
await injectScript(null, {file: "thirdParty/jquery-2.0.3.js"});
await injectScript(null, {file: "work.js"});
doSomethingElse();
} catch (err) {
console.error(err);
}
Note, in Firefox you can just use browser.tabs.executeScript
as it will return a Promise.
It happens because you have not installed the minSdkVersion or targetSdkVersion in you’re computer. I've tested it right now.
For example, if you have those lines in your Manifest.xml:
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
And you have installed only the API17 in your computer, it will report you an error. If you want to test it, try installing the other API version (in this case, API 8).
Even so, it's not an important error. It doesn't mean that your app is wrong.
Sorry about my expression. English is not my language. Bye!
First get the size of screen.
Size size = MediaQuery.of(context).size;
After this you can get width
and multiply it with 0.5
to get 50% of screen width.
double width50 = size.width * 0.5;
But problem generally comes in height
, by default when we use
double screenHeight = size.height;
The height we get is global height which includes StatusBar
+ notch
+ AppBar
height. So, in order to get the left height of the device, we need to subtract padding
height (StatusBar
+ notch
) and AppBar
height from total height. Here is how we do it.
double abovePadding = MediaQuery.of(context).padding.top;
double appBarHeight = appBar.preferredSize.height;
double leftHeight = screenHeight - abovePadding - appBarHeight;
Now we can use following to get 50% of our screen in height.
double height50 = leftHeight * 0.5
Use
__DIR__
to get the current path of the script and this should fix your problem.
So:
require_once(__DIR__.'/../class/user.php');
This will prevent cases where you can run a PHP script from a different folder and therefore the relatives paths will not work.
Edit: slash problem fixed
None of solutions on this page works correctly and universally for all levels and long (wrapped) paragraphs. It’s really tricky to achieve a consistent indentation due to variable size of marker (1., 1.2, 1.10, 1.10.5, …); it can’t be just “faked,” not even with a precomputed margin/padding for each possible indentation level.
I finally figured out a solution that actually works and doesn’t need any JavaScript.
It’s tested on Firefox 32, Chromium 37, IE 9 and Android Browser. Doesn't work on IE 7 and previous.

}

You have to grant the Superuser
right to the shell app (com.anroid.shell
).
In my case, I use Magisk to root my phone Nexsus 6P (Oreo 8.1). So I can grant Superuser
right in the Magisk Manager
app, whih is in the left upper option menu.
it stands for your website where your app is running on. like you have made an app www.xyz.pqr then you will type this www.xyz.pqr in App domain the site where your app is running on should be secure and valid
$watchCollection accomplishes what you want to do. Below is an example copied from angularjs website http://docs.angularjs.org/api/ng/type/$rootScope.Scope While it's convenient, the performance needs to be taken into consideration especially when you watch a large collection.
$scope.names = ['igor', 'matias', 'misko', 'james'];
$scope.dataCount = 4;
$scope.$watchCollection('names', function(newNames, oldNames) {
$scope.dataCount = newNames.length;
});
expect($scope.dataCount).toEqual(4);
$scope.$digest();
//still at 4 ... no changes
expect($scope.dataCount).toEqual(4);
$scope.names.pop();
$scope.$digest();
//now there's been a change
expect($scope.dataCount).toEqual(3);
This works for me.
var selecteditems = [];

When I tried to select the development provisioning profile in Code Signing Identity is would say "profile doesn't match any valid certificate". So when I followed the two step process below it worked:
1) Under "Code Signing Identity" for Development change to "Don't Code Sign".
2) Then Under "Code Signing Identity" for Development you will be able to select your provisioning profile for Development.
Drove me nuts, but stumbled upon the solution.
By "shallow copying" it means the content of the dictionary is not copied by value, but just creating a new reference.
>>> a = {1: [1,2,3]}
>>> b = a.copy()
>>> a, b
({1: [1, 2, 3]}, {1: [1, 2, 3]})
>>> a[1].append(4)
>>> a, b
({1: [1, 2, 3, 4]}, {1: [1, 2, 3, 4]})
In contrast, a deep copy will copy all contents by value.
>>> import copy
>>> c = copy.deepcopy(a)
>>> a, c
({1: [1, 2, 3, 4]}, {1: [1, 2, 3, 4]})
>>> a[1].append(5)
>>> a, c
({1: [1, 2, 3, 4, 5]}, {1: [1, 2, 3, 4]})
So:
b = a
: Reference assignment, Make a
and b
points to the same object.
b = a.copy()
: Shallow copying, a
and b
will become two isolated objects, but their contents still share the same reference
b = copy.deepcopy(a)
: Deep copying, a
and b
's structure and content become completely isolated.
You can give the tr an id and do it.
tr#element{
background-color: green;
cursor: pointer;
height: 30px;
}
tr#element:hover{
background-color: blue;
cursor: pointer;
}
<table width="400px">
<tr id="element">
<td></td>
</tr>

If anybody comes here because they are looking to echo a blank line from a MINGW make makefile, I used
@cmd /c echo.
simply using echo.
causes the dreaded process_begin: CreateProcess(NULL, echo., ...) failed.
error message.
I hope this helps at least one other person out there :)

li {
display: inline-block;

Works for me also.
None of the answers include the overhead size and the metadata sizes of tables.
Here is a more accurate estimation of the "disk space" allocated by a database.
SELECT ROUND((SUM(data_length+index_length+data_free) + (COUNT(*) * 300 * 1024))/1048576+150, 2) AS MegaBytes FROM information_schema.TABLES WHERE table_schema = 'DATABASE-NAME'
Yes. But place your "test" after the comma if you want the column...
> A <- matrix(sample(1:12,12,T),ncol=4)
> rownames(A) <- letters[1:3]
> colnames(A) <- letters[11:14]
> A[,"l"]
a b c

see also help(Extract)
for Oracle Database 10g users:
alter table mytable modify(mycolumn null);
You get "ORA-01735: invalid ALTER TABLE option" when you try otherwise
ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;
Use the DateTime class instead, as it supports timezones. The DateTime equivalent of date()
is DateTime::format
.
An extremely helpful wrapper for DateTime is Carbon - definitely give it a look.
You'll want to store in the database as UTC and convert on the application level.
String.prototype.startsWith
is a standard method in the most recent version of JavaScript, ES6.
Looking at the compatibility table below, we can see that it is supported on all current major platforms, except versions of Internet Explorer.
+-------------------------------------------------------------------------------+
¦ Feature ¦ Chrome ¦ Firefox ¦ Edge ¦ Internet Explorer ¦ Opera ¦ Safari ¦
¦---------------+--------+---------+-------+-------------------+-------+--------¦
¦ Basic Support ¦ 41+ ¦ 17+ ¦ (Yes) ¦ No Support ¦ 28 ¦ 9 ¦
+-------------------------------------------------------------------------------+
You'll need to implement .startsWith
yourself. Here is the polyfill:
if (!String.prototype.startsWith) {
String.prototype.startsWith = function(searchString, position) {
position = position || 0;
return this.indexOf(searchString, position) === position;
};
}
In Java 9, you can use following new method, LocalDate::datesUntil
:
LocalDate start = LocalDate.of(2017, 2, 1);
LocalDate end = LocalDate.of(2017, 2, 28);
Stream<LocalDate> dates = start.datesUntil(end.plusDays(1));
List<LocalDate> list = dates.collect(Collectors.toList());
The new method datesUntil(...)
works with an exclusive end date, hence the shown hack to add a day.
Once you have obtained a stream you can exploit all the features offered by java.util.stream
- or java.util.function
-packages. Working with streams has become so simple compared with earlier approaches based on customized for- or while-loops.
Or if you look for a stream-based solution which operates on inclusive dates by default but can also be configured otherwise then you might find the class DateInterval in my library Time4J interesting because it offers a lot of special features around date streams including a performant spliterator which is faster than in Java-9:
PlainDate start = PlainDate.of(2017, 2, 1);
PlainDate end = start.with(PlainDate.DAY_OF_MONTH.maximized());
Stream<PlainDate> stream = DateInterval.streamDaily(start, end);
Or even simpler in case of full months:
Stream<PlainDate> februaryDates = CalendarMonth.of(2017, 2).streamDaily();
List<LocalDate> list =
februaryDates.map(PlainDate::toTemporalAccessor).collect(Collectors.toList());
In .NET Core WebAPI (version 3.0 and above):
var requestUrl = $"{Request.Scheme}://{Request.Host.Value}/";
The code below reads for any text files available in the directory which contains the script we are running. Then it opens every text file and stores the words of the text line into a list. After store the words we print each word line by line
import os, fnmatch
listOfFiles = os.listdir('.')
pattern = "*.txt"
store = []
for entry in listOfFiles:
if fnmatch.fnmatch(entry, pattern):
_fileName = open(entry,"r")
if _fileName.mode == "r":
content = _fileName.read()
contentList = content.split(" ")
for i in contentList:
if i != '\n' and i != "\r\n":
store.append(i)
for i in store:
print(i)
This sample shows how to read a string from a MemoryStream, in which I've used a serialization (using DataContractJsonSerializer), pass the string from some server to client, and then, how to recover the MemoryStream from the string passed as parameter, then, deserialize the MemoryStream.
I've used parts of different posts to perform this sample.
Hope that this helps.

This works great if a straight copy is in order. If the situation calls for creating new objects from templates, I usually wrap the template div in a hidden storage div and use jquery's html() in conjunction with clone() applying the following technique:
<style>
#element-storage {
display: none;
top: 0;
right: 0;
position: fixed;
width: 0;
height: 0;
}
</style>
<script>
$("#new-div").append($("#template").clone().html(function(index, oldHTML){
// .. code to modify template, e.g. below:
var newHTML = "";
newHTML = oldHTML.replace("[firstname]", "Tom");
newHTML = newHTML.replace("[lastname]", "Smith");
// newHTML = newHTML.replace(/[Example Replace String]/g, "Replacement"); // regex for global replace
return newHTML;
}));
</script>
<div id="element-storage">
<div id="template">
<p>Hello [firstname] [lastname]</p>
</div>
</div>
<div id="new-div">
</div>
