In my situation, our IT department made MFA mandatory for our domain. This means we can only use option 3 in this Microsoft article to send email. Option 3 involves setting up an SMTP relay using an Office365 Connector.
I face the same problem, and think that I do know why this happens.
The gmail account that I use is normally used from India, and the webserver that I use is located in The Netherlands.
Google notifies that there was a login attempt from am unusualy location and requires to login from that location via a web browser.
Furthermore I had to accept suspicious access to the gmail account via https://security.google.com/settings/security/activity
But in the end my problem is not yet solved, because I have to login to gmail from a location in The Netherlands.
I hope this will help you a little! (sorry, I do not read email replies on this email address)
I'm a google apps for business subscriber and I spend the last couple hours just dealing with this, even after having all the correct settings (smtp, port, enableSSL, etc). Here's what worked for me and the web sites that were throwing the 5.5.1 error when trying to send an email:
After doing this my email forms from the website were working again. Good luck!
For anyone who stumbles across this post looking for a solution and you've set up SMTP sendgrid via Azure.
The username is not the username you set up when you've created the sendgrid object in azure. To find your username;
Hope this helps!
The problem with me is that I have so many different versions of python, so it opens up a different python3.7 even after I did brew link. I did the following additional steps to make it default after linking
First, open up the document setting up the path of python
nano ~/.bash_profile
Then something like this shows up:
# Setting PATH for Python 3.7
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.7/bin:${PATH}"
export PATH
# Setting PATH for Python 3.6
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
export PATH
The thing here is that my Python for brew framework is not in the Library Folder!! So I changed the framework for python 3.7, which looks like follows in my system
# Setting PATH for Python 3.7
# The original version is saved in .bash_profile.pysave
PATH="/usr/local/Frameworks/Python.framework/Versions/3.7/bin:${PATH}"
export PATH
Change and save the file. Restart the computer, and typing in python3.7
, I get the python I installed for brew.
Not sure if my case is applicable to everyone, but worth a try. Not sure if the framework path is the same for everyone, please made sure before trying out.
Firstly, use these settings for Google:
$mail->IsSMTP();
$mail->Host = "smtp.gmail.com";
$mail->SMTPAuth = true;
$mail->SMTPSecure = "tls"; //edited from tsl
$mail->Username = "myEmail";
$mail->Password = "myPassword";
$mail->Port = "587";
But also, what firewall have you got set up?
If you're filtering out TCP ports 465/995, and maybe 587, you'll need to configure some exceptions or take them off your rules list.
I've searched and tried different things for hours.. To summarize, I had to take into consideration the following points:
smtp.gmail.com
instead of smtp.google.com
client.UseDefaultCredentials = false;
before setting credentialsclient.EnableSsl = true;
If these steps didn't help, check this answer.
Perhaps, you can find something useful on this System.Net.Mail FAQ too.
You must to have installed php_openssl.dll, if you use wampserver it's pretty easy, search and apply the extension for PHP.
In the example change this:
//Set the hostname of the mail server
$mail->Host = 'smtp.gmail.com';
//Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission 465 ssl
$mail->Port = 465;
//Set the encryption system to use - ssl (deprecated) or tls
$mail->SMTPSecure = 'ssl';
and then you recived an email from gmail talking about to enable the option to Less Safe Access Applications here https://www.google.com/settings/security/lesssecureapps
I recommend you change the password and encrypt it constantly
WE had this issue. everything was setup fine in terms of permissions and security.
after MUCH needling around in the haystack. the issue was some sort of heuristics. in the email body , anytime a certain email address was listed, we would get the above error message from our exchange server.
it took 2 days of crazy testing and hair pulling to find this.
so if you have checked everything out, try changing the email body to only the word 'test'. If after that, your email goes out fine, you are having some sort of spam/heuristic filter issue like we were
I have found the answer to this, and it is annoyingly/frustratingly simple! Basically the reply to addresses needed to be added before the from address as such:
$mail->addReplyTo('[email protected]', 'Reply to name');
$mail->SetFrom('[email protected]', 'Mailbox name');
Looking at the phpmailer code in more detail this is the offending line:
public function SetFrom($address, $name = '',$auto=1) {
$address = trim($address);
$name = trim(preg_replace('/[\r\n]+/', '', $name)); //Strip breaks and trim
if (!self::ValidateAddress($address)) {
$this->SetError($this->Lang('invalid_address').': '. $address);
if ($this->exceptions) {
throw new phpmailerException($this->Lang('invalid_address').': '.$address);
}
echo $this->Lang('invalid_address').': '.$address;
return false;
}
$this->From = $address;
$this->FromName = $name;
if ($auto) {
if (empty($this->ReplyTo)) {
$this->AddAnAddress('ReplyTo', $address, $name);
}
if (empty($this->Sender)) {
$this->Sender = $address;
}
}
return true;
}
Specifically this line:
if (empty($this->ReplyTo)) {
$this->AddAnAddress('ReplyTo', $address, $name);
}
Thanks for your help everyone!
Just need to try this:
string smtpAddress = "smtp.gmail.com";
int portNumber = 587;
bool enableSSL = true;
string emailFrom = "companyemail";
string password = "password";
string emailTo = "Your email";
string subject = "Hello!";
string body = "Hello, Mr.";
MailMessage mail = new MailMessage();
mail.From = new MailAddress(emailFrom);
mail.To.Add(emailTo);
mail.Subject = subject;
mail.Body = body;
mail.IsBodyHtml = true;
using (SmtpClient smtp = new SmtpClient(smtpAddress, portNumber))
{
smtp.Credentials = new NetworkCredential(emailFrom, password);
smtp.EnableSsl = enableSSL;
smtp.Send(mail);
}
I had actually done this from Django a while back. Open up a legitimate GMail account & enter the credentials here. Here's my code -
from email import Encoders
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.MIMEMultipart import MIMEMultipart
def sendmail(to, subject, text, attach=[], mtype='html'):
ok = True
gmail_user = settings.EMAIL_HOST_USER
gmail_pwd = settings.EMAIL_HOST_PASSWORD
msg = MIMEMultipart('alternative')
msg['From'] = gmail_user
msg['To'] = to
msg['Cc'] = '[email protected]'
msg['Subject'] = subject
msg.attach(MIMEText(text, mtype))
for a in attach:
part = MIMEBase('application', 'octet-stream')
part.set_payload(open(attach, 'rb').read())
Encoders.encode_base64(part)
part.add_header('Content-Disposition','attachment; filename="%s"' % os.path.basename(a))
msg.attach(part)
try:
mailServer = smtplib.SMTP("smtp.gmail.com", 687)
mailServer.ehlo()
mailServer.starttls()
mailServer.ehlo()
mailServer.login(gmail_user, gmail_pwd)
mailServer.sendmail(gmail_user, [to,msg['Cc']], msg.as_string())
mailServer.close()
except:
ok = False
return ok
Try to send an e-mail through that SMTP server manually/from an interactive mailer (e.g. Mozilla Thunderbird). From the errors, it seems the server won't accept your credentials. Is that SMTP running on the port, or is it SSL+SMTP? You don't seem to be using secure connection in the code you've posted, and I'm not sure if PHPMailer actually supports SSL+SMTP.
(First result of googling your SMTP server's hostname: http://podpora.ebola.cz/idx.php/0/006/article/Strucny-technicky-popis-nastaveni-sluzeb.html seems to say "SMTPs mail sending: secure SSL connection,port: 465" . )
It looks like PHPMailer does support SSL; at least from this. So, you'll need to change this:
define('SMTP_SERVER', 'smtp.ebola.cz');
into this:
define('SMTP_SERVER', 'ssl://smtp.ebola.cz');

If you have 2-Step Verification step up on your Gmail account, you will need to generate an App password. https://support.google.com/accounts/answer/185833?p=app_passwords_sa&hl=en&visit_id=636903322072234863-1319515789&rd=1 Select How to generate an App password option and follow the steps provided. Copy and paste the generated App password somewhere as you will not be able to recover it after you click DONE.
All the previous answers are good to me. But a straight forward answer on my side would come from https://github.com/kubernetes/dashboard/wiki/Creating-sample-user#bearer-token. Just use kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')
. You will have many values for some keys (Name
, Namespace
, Labels
, ..., token
). The most important is the token
that corresponds to your name. copy that token and paste it in the token box. Hope this helps.
.NET Core is a free and open-source, managed computer software framework for Windows, Linux, and macOS operating systems. It is an open source, cross platform successor to .NET Framework.
.NET Core applications are supported on Windows, Linux, and macOS. In a nutshell .NET Core is similar to .NET framework, but it is cross-platform, i.e., it allows the .NET applications to run on Windows, Linux and MacOS. .NET framework applications can only run on the Windows system. So the basic difference between .NET framework and .NET core is that .NET Core is cross platform and .NET framework only runs on Windows.
Furthermore, .NET Core has built-in dependency injection by Microsoft and you do not have to use third-party software/DLL files for dependency injection.
As pointed by Breedly and Liang, Ashok's solution will prevent you from getting the select value when posting the form.
One slightly different, but still imperfect, way to solve that would be:
class waypointForm(forms.Form):
def __init__(self, user, *args, **kwargs):
self.base_fields['waypoints'].choices = self._do_the_choicy_thing()
super(waypointForm, self).__init__(*args, **kwargs)
This could cause some concurrence problems, though.
You can use splash screen in your first loading Activity like this:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread welcomeThread = new Thread() {
@Override
public void run() {
try {
super.run();
sleep(10000); //Delay of 10 seconds
} catch (Exception e) {
} finally {
Intent i = new Intent(SplashActivity.this,
MainActivity.class);
startActivity(i);
finish();
}
}
};
welcomeThread.start();
}
Hope this code helps you.
I had issues with the answers here in converting the deviceToken Data object to a string to send to my server with the current beta of Xcode 8. Especially the one that was using deviceToken.description as in 8.0b6 that would return "32 Bytes" which isn't very useful :)
This is what worked for me...
Create an extension on Data to implement a "hexString" method:
extension Data {
func hexString() -> String {
return self.reduce("") { string, byte in
string + String(format: "%02X", byte)
}
}
}
And then use that when you receive the callback from registering for remote notifications:
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let deviceTokenString = deviceToken.hexString()
// Send to your server here...
}
For a data.table, assigning the column to NULL removes it:
DT[,c("col1", "col1", "col2", "col2")] <- NULL
^
|---- Notice the extra comma if DT is a data.table
... which is the equivalent of:
DT$col1 <- NULL
DT$col2 <- NULL
DT$col3 <- NULL
DT$col4 <- NULL
The equivalent for a data.frame is:
DF[c("col1", "col1", "col2", "col2")] <- NULL
^
|---- Notice the missing comma if DF is a data.frame
Q. Why is there a comma in the version for data.table, and no comma in the version for data.frame?
A. As data.frames are stored as a list of columns, you can skip the comma. You could also add it in, however then you will need to assign them to a list of NULL
s, DF[, c("col1", "col2", "col3")] <- list(NULL)
.
If 'somescript.py' isn't something you could normally execute directly from the command line (I.e., $: somescript.py
works), then you can't call it directly using call.
Remember that the way Popen works is that the first argument is the program that it executes, and the rest are the arguments passed to that program. In this case, the program is actually python, not your script. So the following will work as you expect:
subprocess.call(['python', 'somescript.py', somescript_arg1, somescript_val1,...]).
This correctly calls the Python interpreter and tells it to execute your script with the given arguments.
Note that this is different from the above suggestion:
subprocess.call(['python somescript.py'])
That will try to execute the program called python somscript.py, which clearly doesn't exist.
call('python somescript.py', shell=True)
Will also work, but using strings as input to call is not cross platform, is dangerous if you aren't the one building the string, and should generally be avoided if at all possible.
As Kevin points out, URL Schemes are the only way to communicate between apps. So, no, it's not possible to launch arbitrary apps.
But it is possible to launch any app that registers a URL Scheme, whether it's Apple's, yours, or another developer's. The docs are here:
Defining a Custom URL Scheme for Your App
As for launching the phone, looks like your tel:
link needs to have least three digits before the phone will launch. So you can't just drop into the app without dialing a number.
Default values should start from the year 1000.
For example,
ALTER TABLE mytable last_active DATETIME DEFAULT '1000-01-01 00:00:00'
Hope this helps someone.

I had exactly the same problem with you. And after two days wondering why this occurs to me, I finally got through this by moving the adb.exe from the unreliable software list of the COMODO anti-virus to its reliable software list. At that time, I had tried at least 5 kinds of measures to make the adb work, including all above...
Interesting discussion. I was asking myself this question too. The main difference between fluid and fixed is simply that the fixed layout has a fixed width in terms of the whole layout of the website (viewport). If you have a 960px width viewport each colum has a fixed width which will never change.
The fluid layout behaves different. Imagine you have set the width of your main layout to 100% width. Now each column will only be calculated to it's relative size (i.e. 25%) and streches as the browser will be resized. So based on your layout purpose you can select how your layout behaves.
Here is a good article about fluid vs. flex.

open that file in any text editor and find your missing file ItemGroup.

remove that ItemGroup and open once again your project and build
Problem not solved. To sufficiently model this out and to prevent code replication you'd either need multiple inheritance or mixins. Interfaces with default functions are not sufficient because you cannot hold members in interfaces. Interface modeling leads to code replication in subclasses or statics, which is both evil.
All you can do is to use a custom construction and split it up in more components and compose it all together...

The answers here already are great, but don't necessarily work for custom ViewGroups. To get all custom Views to retain their state, you must override onSaveInstanceState()
and onRestoreInstanceState(Parcelable state)
in each class.
You also need to ensure they all have unique ids, whether they're inflated from xml or added programmatically.
What I came up with was remarkably like Kobor42's answer, but the error remained because I was adding the Views to a custom ViewGroup programmatically and not assigning unique ids.
The link shared by mato will work, but it means none of the individual Views manage their own state - the entire state is saved in the ViewGroup methods.
The problem is that when multiple of these ViewGroups are added to a layout, the ids of their elements from the xml are no longer unique (if its defined in xml). At runtime, you can call the static method View.generateViewId()
to get a unique id for a View. This is only available from API 17.
Here is my code from the ViewGroup (it is abstract, and mOriginalValue is a type variable):
public abstract class DetailRow<E> extends LinearLayout {
private static final String SUPER_INSTANCE_STATE = "saved_instance_state_parcelable";
private static final String STATE_VIEW_IDS = "state_view_ids";
private static final String STATE_ORIGINAL_VALUE = "state_original_value";
private E mOriginalValue;
private int[] mViewIds;
// ...
@Override
protected Parcelable onSaveInstanceState() {
// Create a bundle to put super parcelable in
Bundle bundle = new Bundle();
bundle.putParcelable(SUPER_INSTANCE_STATE, super.onSaveInstanceState());
// Use abstract method to put mOriginalValue in the bundle;
putValueInTheBundle(mOriginalValue, bundle, STATE_ORIGINAL_VALUE);
// Store mViewIds in the bundle - initialize if necessary.
if (mViewIds == null) {
// We need as many ids as child views
mViewIds = new int[getChildCount()];
for (int i = 0; i < mViewIds.length; i++) {
// generate a unique id for each view
mViewIds[i] = View.generateViewId();
// assign the id to the view at the same index
getChildAt(i).setId(mViewIds[i]);
}
}
bundle.putIntArray(STATE_VIEW_IDS, mViewIds);
// return the bundle
return bundle;
}
@Override
protected void onRestoreInstanceState(Parcelable state) {
// We know state is a Bundle:
Bundle bundle = (Bundle) state;
// Get mViewIds out of the bundle
mViewIds = bundle.getIntArray(STATE_VIEW_IDS);
// For each id, assign to the view of same index
if (mViewIds != null) {
for (int i = 0; i < mViewIds.length; i++) {
getChildAt(i).setId(mViewIds[i]);
}
}
// Get mOriginalValue out of the bundle
mOriginalValue = getValueBackOutOfTheBundle(bundle, STATE_ORIGINAL_VALUE);
// get super parcelable back out of the bundle and pass it to
// super.onRestoreInstanceState(Parcelable)
state = bundle.getParcelable(SUPER_INSTANCE_STATE);
super.onRestoreInstanceState(state);
}
}
Here's a different, but super simple approach. To load multiple scripts you can simply append them to body.
var scriptsToLoad = [
"script1.js",
"script2.js",
"script3.js",
];
scriptsToLoad.forEach(function(src) {
var script = document.createElement('script');
script.src = src;
script.async = false;
document.body.appendChild(script);
});
I have the same wonder today, I did on this way :
//<img src="actual.png" alt="myImage" class=myClass>
$('.myClass').attr('src','').promise().done(function() {
$(this).attr('src','img/new.png');
});
I've tried Komodo out a bit, and I really like it so far. Aptana, an Eclipse variant, is also rather useful for a wide variety of things. There's always good ole' VI, too!
You can create a trigger which updates NoofUses
column in Coupon
table whenever
couponid
is used in CouponUse
table
query :
CREATE TRIGGER [dbo].[couponcount] ON [dbo].[couponuse]
FOR INSERT
AS
if EXISTS (SELECT 1 FROM Inserted)
BEGIN
UPDATE dbo.Coupon
SET NoofUses = (SELECT COUNT(*) FROM dbo.CouponUse WHERE Couponid = dbo.Coupon.ID)
end
Object[][] data = {
{"mykey1", "myval1"},
{"mykey2", "myval2"},
{new Date(), new Integer(1)},
};
Yes, this require iteration for searchting value by key, but if you need all of them, this will be the best choice.
Ensure that Enhanced session mode settings are enabled on the Hyper-V host.
Start Hyper-V Manager, and in the Actions section, select "Hyper-V Settings".
Make sure that enhanced session mode is allowed in the Server section. Then, make sure that the enhanced session mode is available in the User section.
Enable Hyper-V Guest Services for your virtual machine
Right-click on Virtual Machine > Settings. Select the Integration Services in the left-lower corner of the menu. Check Guest Service and click OK.
Start a virtual machine and click Show Options in the pop-up windows.
Or click "Edit Session Settings..." in the Actions panel on the right
It may only appear when you're (able to get) connected to it. If it doesn't appear try Starting and then Connecting to the VM while paying close attention to the panel in the Hyper-V Manager.
View local resources. Then, select the "More..." menu.
From there, you can choose which devices to share. Removable drives are especially useful for file sharing.
Choose to "Save my settings for future connections to this virtual machine".
Click Connect. Drive sharing is now complete, and you will see the shared drive in this PC > Network Locations section of Windows Explorer after using the enhanced session mode to sigh to the VM. You should now be able to copy files from a physical machine and paste them into a virtual machine, and vice versa.

I use either the accepted answer's solution, slightly modified to have same length for output as input, or pandas
' version as mentioned in a comment of another answer. I summarize both here with a reproducible example for future reference:
import numpy as np
import pandas as pd
def moving_average(a, n):
ret = np.cumsum(a, dtype=float)
ret[n:] = ret[n:] - ret[:-n]
return ret / n
def moving_average_centered(a, n):
return pd.Series(a).rolling(window=n, center=True).mean().to_numpy()
A = [0, 0, 1, 2, 4, 5, 4]
print(moving_average(A, 3))
# [0. 0. 0.33333333 1. 2.33333333 3.66666667 4.33333333]
print(moving_average_centered(A, 3))
# [nan 0.33333333 1. 2.33333333 3.66666667 4.33333333 nan ]
If your collection type is a List<stuff>
, then the best approach is probably the following:
prods.RemoveAll(s => s.ID == 1)
This only does one pass (iteration) over the list, so should be more efficient than other methods.
If your type is more generically an ICollection<T>
, it might help to write a short extension method if you care about performance. If not, then you'd probably get away with using LINQ (calling Where
or Single
).
Starting simple, with no HTML:
foreach($database as $file) {
echo $file['filename'] . ' at ' . $file['filepath'];
}
And you can otherwise manipulate the fields in the foreach.
It's notable to understand that if you'd like to conditionally add attributes you can also add a dynamic declaration:
<input v-bind="attrs" />
where attrs is declared as an object:
data() {
return {
attrs: {
required: true,
type: "text"
}
}
}
Which will result in:
<input required type="text"/>
Ideal in cases with multiple attributes.
lvalue
means "left value" -- it should be assignable. You cannot change the value of text
since it is an array, not a pointer.
Either declare it as char pointer (in this case it's better to declare it as const char*
):
const char *text;
if(number == 2)
text = "awesome";
else
text = "you fail";
Or use strcpy:
char text[60];
if(number == 2)
strcpy(text, "awesome");
else
strcpy(text, "you fail");
Personally, I don't think there is any real world use for StringBuffer
. When would I ever want to communicate between multiple threads by manipulating a character sequence? That doesn't sound useful at all, but maybe I have yet to see the light :)
I would say static block
is just syntactic sugar. There is nothing you could do with static
block and not with anything else.
To re-use some examples posted here.
This piece of code could be re-written without using static
initialiser.
Method #1: With static
private static final HashMap<String, String> MAP;
static {
MAP.put("banana", "honey");
MAP.put("peanut butter", "jelly");
MAP.put("rice", "beans");
}
Method #2: Without static
private static final HashMap<String, String> MAP = getMap();
private static HashMap<String, String> getMap()
{
HashMap<String, String> ret = new HashMap<>();
ret.put("banana", "honey");
ret.put("peanut butter", "jelly");
ret.put("rice", "beans");
return ret;
}
As @AliK mentioned, this can be done easily by looking at the value of the submit buttons.
When you submit a form, unset variables will evaluate false. If you set both submit buttons to be part of the same form, you can just check and see which button has been set.
HTML:
<form action="handle_user.php" method="POST" /> <input type="submit" value="Save" name="save" /> <input type="submit" value="Submit for Approval" name="approve" /> </form>
PHP
if($_POST["save"]) { //User hit the save button, handle accordingly } //You can do an else, but I prefer a separate statement if($_POST["approve"]) { //User hit the Submit for Approval button, handle accordingly }

Well to obtain all different values in a Dataframe
you can use distinct. As you can see in the documentation that method returns another DataFrame
. After that you can create a UDF
in order to transform each record.
For example:
val df = sc.parallelize(Array((1, 2), (3, 4), (1, 6))).toDF("age", "salary")
// I obtain all different values. If you show you must see only {1, 3}
val distinctValuesDF = df.select(df("age")).distinct

The builtin json
module got included in Python 2.6. Any projects that support versions of Python < 2.6 need to have a fallback. In many cases, that fallback is simplejson
.
First, a definition, since it's pretty important: A stable sort is one that's guaranteed not to reorder elements with identical keys.
Recommendations:
Quick sort: When you don't need a stable sort and average case performance matters more than worst case performance. A quick sort is O(N log N) on average, O(N^2) in the worst case. A good implementation uses O(log N) auxiliary storage in the form of stack space for recursion.
Merge sort: When you need a stable, O(N log N) sort, this is about your only option. The only downsides to it are that it uses O(N) auxiliary space and has a slightly larger constant than a quick sort. There are some in-place merge sorts, but AFAIK they are all either not stable or worse than O(N log N). Even the O(N log N) in place sorts have so much larger a constant than the plain old merge sort that they're more theoretical curiosities than useful algorithms.
Heap sort: When you don't need a stable sort and you care more about worst case performance than average case performance. It's guaranteed to be O(N log N), and uses O(1) auxiliary space, meaning that you won't unexpectedly run out of heap or stack space on very large inputs.
Introsort: This is a quick sort that switches to a heap sort after a certain recursion depth to get around quick sort's O(N^2) worst case. It's almost always better than a plain old quick sort, since you get the average case of a quick sort, with guaranteed O(N log N) performance. Probably the only reason to use a heap sort instead of this is in severely memory constrained systems where O(log N) stack space is practically significant.
Insertion sort: When N is guaranteed to be small, including as the base case of a quick sort or merge sort. While this is O(N^2), it has a very small constant and is a stable sort.
Bubble sort, selection sort: When you're doing something quick and dirty and for some reason you can't just use the standard library's sorting algorithm. The only advantage these have over insertion sort is being slightly easier to implement.
Non-comparison sorts: Under some fairly limited conditions it's possible to break the O(N log N) barrier and sort in O(N). Here are some cases where that's worth a try:
Counting sort: When you are sorting integers with a limited range.
Radix sort: When log(N) is significantly larger than K, where K is the number of radix digits.
Bucket sort: When you can guarantee that your input is approximately uniformly distributed.
I implemented a hasOne
relation in my parent class, defined both the foreign and local key, it returned an object but the columns of the child must be accessed as an array.
i.e. $parent->child['column']
Kind of confusing.
dateDate.Ticks
should give you what you're looking for.
The value of this property represents the number of 100-nanosecond intervals that have elapsed since 12:00:00 midnight, January 1, 0001, which represents DateTime.MinValue. It does not include the number of ticks that are attributable to leap seconds.
If you're really looking for the Linux Epoch time (seconds since Jan 1, 1970), the accepted answer for this question should be relevant.
But if you're actually trying to "compress" a string representation of the date into an int, you should ask yourself why aren't you just storing it as a string to begin with. If you still want to do it after that, Stecya's answer is the right one. Keep in mind it won't fit into an int, you'll have to use a long.
I know that this is a bit of an old post, but all of the regular expressions here are missing one very important component: the support for IDN domain names.
IDN domain names start with xn--. They enable extended UTF-8 characters in domain names. For example, did you know "?.com" is a valid domain name? Yeah, "love heart dot com"! To validate the domain name, you need to let http://xn--c6h.com/ pass the validation.
Note, to use this regex, you will need to convert the domain to lower case, and also use an IDN library to ensure you encode domain names to ACE (also known as "ASCII Compatible Encoding"). One good library is GNU-Libidn.
idn(1) is the command line interface to the internationalized domain name library. The following example converts the host name in UTF-8 into ACE encoding. The resulting URL https://nic.xn--flw351e/ can then be used as ACE-encoded equivalent of https://nic.??/.
$ idn --quiet -a nic.??
nic.xn--flw351e
This magic regular expression should cover most domains (although, I am sure there are many valid edge cases that I have missed):
^((?!-))(xn--)?[a-z0-9][a-z0-9-_]{0,61}[a-z0-9]{0,1}\.(xn--)?([a-z0-9\-]{1,61}|[a-z0-9-]{1,30}\.[a-z]{2,})$
When choosing a domain validation regex, you should see if the domain matches the following:
If these three domains do not pass, your regular expression may be not allowing legitimate domains!
Check out The Internationalized Domain Names Support page from Oracle's International Language Environment Guide for more information.
Feel free to try out the regex here: http://www.regexr.com/3abjr
ICANN keeps a list of tlds that have been delegated which can be used to see some examples of IDN domains.
Edit:
^(((?!-))(xn--|_{1,1})?[a-z0-9-]{0,61}[a-z0-9]{1,1}\.)*(xn--)?([a-z0-9][a-z0-9\-]{0,60}|[a-z0-9-]{1,30}\.[a-z]{2,})$
This regular expression will stop domains that have '-' at the end of a hostname as being marked as being valid. Additionally, it allows unlimited subdomains.
I've been forgetting to share my solution, I couldn't find a way to do this without using JS. There are some corner cases where @Jeffery A Wooden's suggested CSS just wont cover.
This is what I apply to all of my UI containers, no need to apply to each element since it recuses on all the child elements.
CSS:
.unselectable {
/* For Opera and <= IE9, we need to add unselectable="on" attribute onto each element */
/* Check this site for more details: http://help.dottoro.com/lhwdpnva.php */
-moz-user-select: none; /* These user-select properties are inheritable, used to prevent text selection */
-webkit-user-select: none;
-ms-user-select: none; /* From IE10 only */
user-select: none; /* Not valid CSS yet, as of July 2012 */
-webkit-user-drag: none; /* Prevents dragging of images/divs etc */
user-drag: none;
}
JS:
var makeUnselectable = function( $target ) {
$target
.addClass( 'unselectable' ) // All these attributes are inheritable
.attr( 'unselectable', 'on' ) // For IE9 - This property is not inherited, needs to be placed onto everything
.attr( 'draggable', 'false' ) // For moz and webkit, although Firefox 16 ignores this when -moz-user-select: none; is set, it's like these properties are mutually exclusive, seems to be a bug.
.on( 'dragstart', function() { return false; } ); // Needed since Firefox 16 seems to ingore the 'draggable' attribute we just applied above when '-moz-user-select: none' is applied to the CSS
$target // Apply non-inheritable properties to the child elements
.find( '*' )
.attr( 'draggable', 'false' )
.attr( 'unselectable', 'on' );
};
This was way more complicated than it needed to be.
Vertical align bottom and remove the float seems to work. I then had a margin issue, but the -2px keeps them from getting pushed down (and they still don't overlap)
.profile-header > div {
display: inline-block;
vertical-align: bottom;
float: none;
margin: -2px;
}
.profile-header {
margin-bottom:20px;
border:2px solid green;
display: table-cell;
}
.profile-pic {
height:300px;
border:2px solid red;
}
.profile-about {
border:2px solid blue;
}
.profile-about2 {
border:2px solid pink;
}

This is a message for me in the future:
Just use: (unsigned)!((int)0)
It creates the largest possible number in any machine by assigning all bits to 1s (ones) and then casts it to unsigned
Even better
#define INF (unsigned)!((int)0)
And then just use INF in your code

Only checked

checked="yes"
and checked="true"
are particularly bad as they imply that checked="no"

will set the default state to be unchecked … which they will not.
The following worked for me after hours of trying
$http.post("http://localhost:8080/yourresource", parameter, {headers:
{'Content-Type': 'application/json', 'Access-Control-Allow-Origin': '*' } }).
However following code did not work, I am unclear as to why, hopefully someone can improve this answer.
$http({ method: 'POST', url: "http://localhost:8080/yourresource",
parameter,
headers: {'Content-Type': 'application/json',
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Methods': 'POST'}
})
Code:
var date = new Date('2011', '01', '02');_x000D_
alert('the original date is ' + date);_x000D_
var newdate = new Date(date);_x000D_
_x000D_
newdate.setDate(newdate.getDate() - 7); // minus the date_x000D_
_x000D_
var nd = new Date(newdate);_x000D_
alert('the new date is ' + nd);
_x000D_
Using Datepicker:
$("#in").datepicker({
minDate: 0,
onSelect: function(dateText, inst) {
var actualDate = new Date(dateText);
var newDate = new Date(actualDate.getFullYear(), actualDate.getMonth(), actualDate.getDate()+1);
$('#out').datepicker('option', 'minDate', newDate );
}
});
$("#out").datepicker();?
Extra stuff that might come handy:
getDate() Returns the day of the month (from 1-31)
getDay() Returns the day of the week (from 0-6)
getFullYear() Returns the year (four digits)
getHours() Returns the hour (from 0-23)
getMilliseconds() Returns the milliseconds (from 0-999)
getMinutes() Returns the minutes (from 0-59)
getMonth() Returns the month (from 0-11)
getSeconds() Returns the seconds (from 0-59)

I investigate i knew that the jquery script need to load in order that why it not worked in your case. Because $ symbol mentioned in code not understand unless you load Jquery 1.9.1 at first. Load like follows
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.2.1.min.js"></script>
<link href="https://cdnjs.cloudflare.com/ajax/libs/toastr.js/2.0.1/css/toastr.css" rel="stylesheet"/>

Then it will work fine
(at least) for Django 1.8:
If you use
if settings.DEBUG:
urlpatterns.append(url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}))
as described above, make sure that no "catch all" url pattern, directing to a default view, comes before that in urlpatterns = []. As .append will put the added scheme to the end of the list, it will of course only be tested if no previous url pattern matches. You can avoid that by using something like this where the "catch all" url pattern is added at the very end, independent from the if statement:
if settings.DEBUG:
urlpatterns.append(url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}))
urlpatterns.append(url(r'$', 'views.home', name='home')),
In my case it was
username : root
password : mysql
Using : Wamp server 3.1.0
There is a Superuser Roles: root, which is a Built-In Roles, may meet your need.
Furthermore, if in the same Jenkins project we need to checkout several private GitHub repositories into several separate dirs under a project root. How can we do it please?
The Jenkin's Multiple SCMs Plugin has solved the several repositories problem for me very nicely. I have just got working a project build that checks out four different git repos under a common folder. (I'm a bit reluctant to use git super-projects as suggested previously by Lukasz Rzanek, as git is complex enough without submodules.)

I had trouble with a .pfx file with openconnect. Renaming didn't solve the problem. I used keytool to convert it to .p12 and it worked.
keytool -importkeystore -destkeystore new.p12 -deststoretype pkcs12 -srckeystore original.pfx
In my case the password for the new file (new.p12) had to be the same as the password for the .pfx file.
The web server is prompting you for a SPNEGO (Simple and Protected GSSAPI Negotiation Mechanism) token.
This is a Microsoft invention for negotiating a type of authentication to use for Web SSO (single-sign-on):
See:
In HTML the style tag has the following syntax:
style="property1:value1;property2:value2"
so in your case:
<h2 style="text-align:center;font-family:tahoma">TITLE</h2>
Hope this helps.
InOrder
helps you to do that.
ServiceClassA firstMock = mock(ServiceClassA.class);
ServiceClassB secondMock = mock(ServiceClassB.class);
Mockito.doNothing().when(firstMock).methodOne();
Mockito.doNothing().when(secondMock).methodTwo();
//create inOrder object passing any mocks that need to be verified in order
InOrder inOrder = inOrder(firstMock, secondMock);
//following will make sure that firstMock was called before secondMock
inOrder.verify(firstMock).methodOne();

I had similar issues browsing to secure sites (https://) when using Burp (or at least an issue that would bring you to this page when searching Google):
ssl_error_no_cypher_overlap
in FirefoxERR_SSL_VERSION_OR_CIPHER_MISMATCH
in ChromeIt turned out to be an issue with using Java 8. When I switched to Java 7, the problem stopped.
I was trying to resize some images for a slideshow video and because of that, I wanted not just one max dimension, but a max width and a max height (the size of the video frame).
And there was always the possibility of a portrait video...
The Image.thumbnail
method was promising, but I could not make it upscale a smaller image.
So after I couldn't find an obvious way to do that here (or at some other places), I wrote this function and put it here for the ones to come:
from PIL import Image
def get_resized_img(img_path, video_size):
img = Image.open(img_path)
width, height = video_size # these are the MAX dimensions
video_ratio = width / height
img_ratio = img.size[0] / img.size[1]
if video_ratio >= 1: # the video is wide
if img_ratio <= video_ratio: # image is not wide enough
width_new = int(height * img_ratio)
size_new = width_new, height
else: # image is wider than video
height_new = int(width / img_ratio)
size_new = width, height_new
else: # the video is tall
if img_ratio >= video_ratio: # image is not tall enough
height_new = int(width / img_ratio)
size_new = width, height_new
else: # image is taller than video
width_new = int(height * img_ratio)
size_new = width_new, height
return img.resize(size_new, resample=Image.LANCZOS)
In my case, I needed to check for the existence of a method with a specific name, so I used an interface for that
var plugin = this.pluginFinder.GetPluginIfInstalled<IPlugin>(pluginName) as dynamic;
if (plugin != null && plugin is ICustomPluginAction)
{
plugin.CustomPluginAction(action);
}
Also, interfaces can contain more than just methods:
Interfaces can contain methods, properties, events, indexers, or any combination of those four member types.

Your variable declarations and their scope are correct. The problem you are facing is that the first AJAX request may take a little bit time to finish. Therefore, the second URL will be filled with the value of sID
before the its content has been set. You have to remember that AJAX request are normally asynchronous, i.e. the code execution goes on while the data is being fetched in the background.
You have to nest the requests:
$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE" , function(name){ obj = name; // sID is only now available! sID = obj.id; console.log(sID); });
name.id
is sufficient unless you really need the other variables outside the function.$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE" , function(name){ // We don't need sID or obj here - name.id is sufficient console.log(name.id); doSecondRequest(name.id); }); /// TODO Choose a better name function doSecondRequest(sID) { $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function(stats){ console.log(stats); }); }
Hapy New Year :)
The type and definition of foreign key field and reference must be equal. This means your foreign key disallows changing the type of your field.
One solution would be this:
LOCK TABLES
favorite_food WRITE,
person WRITE;
ALTER TABLE favorite_food
DROP FOREIGN KEY fk_fav_food_person_id,
MODIFY person_id SMALLINT UNSIGNED;
Now you can change you person_id
ALTER TABLE person MODIFY person_id SMALLINT UNSIGNED AUTO_INCREMENT;
recreate foreign key
ALTER TABLE favorite_food
ADD CONSTRAINT fk_fav_food_person_id FOREIGN KEY (person_id)
REFERENCES person (person_id);
UNLOCK TABLES;
EDIT: Added locks above, thanks to comments
You have to disallow writing to the database while you do this, otherwise you risk data integrity problems.
I've added a write lock above
All writing queries in any other session than your own ( INSERT, UPDATE, DELETE
) will wait till timeout or UNLOCK TABLES

EDIT 2: OP asked for a more detailed explanation of the line "The type and definition of foreign key field and reference must be equal. This means your foreign key disallows changing the type of your field."
From MySQL 5.5 Reference Manual: FOREIGN KEY Constraints
Corresponding columns in the foreign key and the referenced key must have similar internal data types inside InnoDB so that they can be compared without a type conversion. The size and sign of integer types must be the same. The length of string types need not be the same. For nonbinary (character) string columns, the character set and collation must be the same.
While the DateTime.Kind property does not have a setter, the static method DateTime.SpecifyKind creates a DateTime instance with a specified value for Kind.

If you're really bent upon converting Integer to String value, I suggest use String.valueOf(YourIntegerVariable). More details can be found at: http://www.tutorialspoint.com/java/java_string_valueof.htm
The sql array type is not neccessary. Not if the element type is a primitive one. (Varchar, number, date,...)
Very basic sample:
declare
type TPidmList is table of sgbstdn.sgbstdn_pidm%type;
pidms TPidmList;
begin
select distinct sgbstdn_pidm
bulk collect into pidms
from sgbstdn
where sgbstdn_majr_code_1 = 'HS04'
and sgbstdn_program_1 = 'HSCOMPH';
-- do something with pidms
open :someCursor for
select value(t) pidm
from table(pidms) t;
end;
When you want to reuse it, then it might be interesting to know how that would look like. If you issue several commands than those could be grouped in a package. The private package variable trick from above has its downsides. When you add variables to a package, you give it state and now it doesn't act as a stateless bunch of functions but as some weird sort of singleton object instance instead.
e.g. When you recompile the body, it will raise exceptions in sessions that already used it before. (because the variable values got invalided)
However, you could declare the type in a package (or globally in sql), and use it as a paramter in methods that should use it.
create package Abc as
type TPidmList is table of sgbstdn.sgbstdn_pidm%type;
function CreateList(majorCode in Varchar,
program in Varchar) return TPidmList;
function Test1(list in TPidmList) return PLS_Integer;
-- "in" to make it immutable so that PL/SQL can pass a pointer instead of a copy
procedure Test2(list in TPidmList);
end;
create package body Abc as
function CreateList(majorCode in Varchar,
program in Varchar) return TPidmList is
result TPidmList;
begin
select distinct sgbstdn_pidm
bulk collect into result
from sgbstdn
where sgbstdn_majr_code_1 = majorCode
and sgbstdn_program_1 = program;
return result;
end;
function Test1(list in TPidmList) return PLS_Integer is
result PLS_Integer := 0;
begin
if list is null or list.Count = 0 then
return result;
end if;
for i in list.First .. list.Last loop
if ... then
result := result + list(i);
end if;
end loop;
end;
procedure Test2(list in TPidmList) as
begin
...
end;
return result;
end;
How to call it:
declare
pidms constant Abc.TPidmList := Abc.CreateList('HS04', 'HSCOMPH');
xyz PLS_Integer;
begin
Abc.Test2(pidms);
xyz := Abc.Test1(pidms);
...
open :someCursor for
select value(t) as Pidm,
xyz as SomeValue
from table(pidms) t;
end;
Set the GroupName
property of both radio buttons to the same value. You could also try using a RadioButtonGroup
, which does this for you automatically.
Another tree implementation loosely based off of Bruno's answer:
class Node:
def __init__(self):
self.name: str = ''
self.children: List[Node] = []
self.parent: Node = self
def __getitem__(self, i: int) -> 'Node':
return self.children[i]
def add_child(self):
child = Node()
self.children.append(child)
child.parent = self
return child
def __str__(self) -> str:
def _get_character(x, left, right) -> str:
if x < left:
return '/'
elif x >= right:
return '\\'
else:
return '|'
if len(self.children):
children_lines: Sequence[List[str]] = list(map(lambda child: str(child).split('\n'), self.children))
widths: Sequence[int] = list(map(lambda child_lines: len(child_lines[0]), children_lines))
max_height: int = max(map(len, children_lines))
total_width: int = sum(widths) + len(widths) - 1
left: int = (total_width - len(self.name) + 1) // 2
right: int = left + len(self.name)
return '\n'.join((
self.name.center(total_width),
' '.join(map(lambda width, position: _get_character(position - width // 2, left, right).center(width),
widths, accumulate(widths, add))),
*map(
lambda row: ' '.join(map(
lambda child_lines: child_lines[row] if row < len(child_lines) else ' ' * len(child_lines[0]),
children_lines)),
range(max_height))))
else:
return self.name
And an example of how to use it:
tree = Node()
tree.name = 'Root node'
tree.add_child()
tree[0].name = 'Child node 0'
tree.add_child()
tree[1].name = 'Child node 1'
tree.add_child()
tree[2].name = 'Child node 2'
tree[1].add_child()
tree[1][0].name = 'Grandchild 1.0'
tree[2].add_child()
tree[2][0].name = 'Grandchild 2.0'
tree[2].add_child()
tree[2][1].name = 'Grandchild 2.1'
print(tree)
Which should output:
Root node / / \ Child node 0 Child node 1 Child node 2 | / \ Grandchild 1.0 Grandchild 2.0 Grandchild 2.1
span
is a inline element which means if you use <br/>
it'll b considered as one line anyway.
Change span
to a block element or add display:block
to your class.

Here is a correct solution. In this case tdata is allocated in the main thread, and there is a space for the thread to place its result.
#include <pthread.h>
#include <stdio.h>
typedef struct thread_data {
int a;
int b;
int result;
} thread_data;
void *myThread(void *arg)
{
thread_data *tdata=(thread_data *)arg;
int a=tdata->a;
int b=tdata->b;
int result=a+b;
tdata->result=result;
pthread_exit(NULL);
}
int main()
{
pthread_t tid;
thread_data tdata;
tdata.a=10;
tdata.b=32;
pthread_create(&tid, NULL, myThread, (void *)&tdata);
pthread_join(tid, NULL);
printf("%d + %d = %d\n", tdata.a, tdata.b, tdata.result);
return 0;
}
If you go to the folder in finder, right click and select "Get Info" you can go to the "Sharing and Permissions" section for the folder and allow "Read & Write" to "everyone"
This is what I do to make symlinks pass with this error. Also brew seems to reset the permissions on the folder also as if you hadn't altered anything
For some reason, it seems that using "text" attribute is the way to go with most browsers. It worked for me
$("#span_id").text("text value to assign");
To clarify some points:
As jro has mentioned, the right way is to use subprocess.communicate
.
Yet, when feeding the stdin
using subprocess.communicate
with input
, you need to initiate the subprocess with stdin=subprocess.PIPE
according to the docs.
Note that if you want to send data to the process’s stdin, you need to create the Popen object with stdin=PIPE. Similarly, to get anything other than None in the result tuple, you need to give stdout=PIPE and/or stderr=PIPE too.
Also qed has mentioned in the comments that for Python 3.4 you need to encode the string, meaning you need to pass Bytes to the input
rather than a string
. This is not entirely true. According to the docs, if the streams were opened in text mode, the input should be a string (source is the same page).
If streams were opened in text mode, input must be a string. Otherwise, it must be bytes.
So, if the streams were not opened explicitly in text mode, then something like below should work:
import subprocess
command = ['myapp', '--arg1', 'value_for_arg1']
p = subprocess.Popen(command, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
output = p.communicate(input='some data'.encode())[0]
I've left the stderr
value above deliberately as STDOUT
as an example.
That being said, sometimes you might want the output of another process rather than building it up from scratch. Let's say you want to run the equivalent of echo -n 'CATCH\nme' | grep -i catch | wc -m
. This should normally return the number characters in 'CATCH' plus a newline character, which results in 6. The point of the echo here is to feed the CATCH\nme
data to grep. So we can feed the data to grep with stdin in the Python subprocess chain as a variable, and then pass the stdout as a PIPE to the wc
process' stdin (in the meantime, get rid of the extra newline character):
import subprocess
what_to_catch = 'catch'
what_to_feed = 'CATCH\nme'
# We create the first subprocess, note that we need stdin=PIPE and stdout=PIPE
p1 = subprocess.Popen(['grep', '-i', what_to_catch], stdin=subprocess.PIPE, stdout=subprocess.PIPE)
# We immediately run the first subprocess and get the result
# Note that we encode the data, otherwise we'd get a TypeError
p1_out = p1.communicate(input=what_to_feed.encode())[0]
# Well the result includes an '\n' at the end,
# if we want to get rid of it in a VERY hacky way
p1_out = p1_out.decode().strip().encode()
# We create the second subprocess, note that we need stdin=PIPE
p2 = subprocess.Popen(['wc', '-m'], stdin=subprocess.PIPE, stdout=subprocess.PIPE)
# We run the second subprocess feeding it with the first subprocess' output.
# We decode the output to convert to a string
# We still have a '\n', so we strip that out
output = p2.communicate(input=p1_out)[0].decode().strip()
This is somewhat different than the response here, where you pipe two processes directly without adding data directly in Python.
Hope that helps someone out.
Before you begin, if you are uncomfortable with a command line, you can do all the following steps using SourceTree, GitExtension, GitHub Desktop, or your favorite tool.
To solve the issue, you might have two scenarios:
1) Fix only remote repository branch which is behind commit
Example: Both branches are on the remote side
ahead === Master branch
behind === Develop branch
Solution:
Clone the repository to the local workspace: this will give you the Master branch which is ahead with commit
git clone repositoryUrl
Create a branch with Develop name and checkout to that branch locally
git checkout -b DevelopBranchName // this command creates and checkout the branch
Pull from the remote Develop branch. Conflict might occur. if so, fix the conflict and commit the changes.
git pull origin DevelopBranchName
Merge the local Develop branch with the remote Develop branch
git merge origin develop
Push the merged branch to the remote Develop branch
git push origin develop
2) Local Master branch is behind the remote Master branch
This means every locally created branch is behind.
Before preceding, you have to commit or stash all the changes you made on the branch that is behind commits.
Solution:
Checkout your local Master branch
git checkout master
Pull from remote Master branch
git pull origin master
Now your local Master is in sync with the remote Branch but other local branches, that branched from the local Master branch, are not in sync with your local Master branch because of the above command. To fix that:
Checkout the branch that is behind your local Master branch
git checkout BranchNameBehindCommit
Merge with the local Master branch
git merge master // Now your branch is in sync with local Master branch
If this branch is on the remote repository, you have to push your changes
git push origin branchBehindCommit
I would consider this more of an old-school C style; it is not really good practice in JavaScript so you should avoid it.

The table above should've been this:
Also assuming a full repair & uninstall the actual values of properties could be:
The WiX Expression Syntax documentation says:
In these expressions, you can use property names (remember that they are case sensitive).
The properties are documented at the Windows Installer Guide (e.g. Installed)

https://lifeboat.com/programs/console.exe is a compiled version of the Visual Basic program described at https://stackoverflow.com/a/4694566/1752929. My version simply sets the buffer height to 32766 which is the maximum buffer height available. It does not adjust anything else. If there is a lot of demand, I could create a more flexible program but generally you can just set other variables in your shortcut layout tab.
Following is the target I use in my shortcut where I wish to start in the f directory. (I have to set the directory this way as Windows won't let you set it any other way if you wish to run the command prompt as administrator.)

You can do it with javascript, and I don't think it needs to be that fancy.
If you have a header.js file and a footer.js.
Then the contents of header.js could be something like
document.write("<div class='header'>header content</div> etc...")
Remember to escape any nested quote characters in the string you are writing. You could then call that from your static templates with
<script type="text/javascript" src="header.js"></script>
and similarly for the footer.js.
Note: I am not recommending this solution - it's a hack and has a number of drawbacks (poor for SEO and usability just for starters) - but it does meet the requirements of the questioner.
You also can lead your initial string, which you are going to check for pattern matching, to lower case. And using in your pattern lower case symbols respectively .
<whatever onclick="doStuff();" onmouseover="in()" onmouseout="out()" />
onclick, onmouseover, onmouseout, etc. events are actually bad for performance (in Internet Explorer mainly, go figure). If you code using Visual Studio, when you run a page with these, every single one of these will create a separate SCRIPT block taking up memory, and thus slowing down performance.
Not to mention you should have a separation of concerns: JavaScript and layouts should be separated!
It is always better to create evenHandlers for any of these events, one event can capture hundreds/thousands of items, instead of creating thousands of separate script blocks for each one!
(Also, everything everyone else is saying.)
I have written lot of scripts to automate daily backups etc. Previously I used XCopy and then moved to Robocopy. Anyways Robocopy and XCopy both are frequently used in terms of file transfers in Windows. Robocopy stands for Robust File Copy. All type of huge file copying both these commands are used but Robocopy has added options which makes copying easier as well as for debugging purposes.
Having said that lets talk about features between these two.
Robocopy becomes handy for mirroring or synchronizing directories. It also checks the files in the destination directory against the files to be copied and doesn't waste time copying unchanged files.
Just like myself, if you are into automation to take daily backups etc, "Run Hours - /RH" becomes very useful without any interactions. This is supported by Robocopy. It allows you to set when copies should be done rather than the time of the command as with XCopy. You will see robocopy.exe process in task list since it will run background to monitor clock to execute when time is right to copy.
Robocopy supports file and directory monitoring with the "/MON" or "/MOT" commands.
Robocopy gives extra support for copying over the "archive" attribute on files, it supports copying over all attributes including timestamps, security, owner, and auditing information.
Hope this helps you.
Use set -u
which will cause any unset argument reference to immediately fail the script.

"??".encode('utf-8')
encode
converts a unicode object to a string
object. But here you have invoked it on a string
object (because you don't have the u). So python has to convert the string
to a unicode
object first. So it does the equivalent of
"??".decode().encode('utf-8')
But the decode fails because the string isn't valid ascii. That's why you get a complaint about not being able to decode.
\s
matches whitespace (spaces, tabs and new lines). \S
is negated \s

You can simplify to:
WHERE a.Country = COALESCE(NULLIF(@Country,0), a.Country);
Yes. You can have a span
within a span
. Your problem stems from something else.
int i = 0;
bool b = Convert.ToBoolean(i);
Yes you can do by using jQuery as:
<script>
$(document).ready(function()
{
$("#username").blur(function()
{
//remove all the class add the messagebox classes and start fading
$("#msgbox").removeClass().addClass('messagebox').text('Checking...').fadeIn("slow");
//check the username exists or not from ajax
$.post("user_availability.php",{ user_name:$(this).val() } ,function(data)
{
if(data=='empty') // if username is empty
{
$("#msgbox").fadeTo(200,0.1,function() //start fading the messagebox
{
//add message and change the class of the box and start fading
$(this).html('Empty user id is not allowed').addClass('messageboxerror').fadeTo(900,1);
});
}
else if(data=='invalid') // if special characters used in username
{
$("#msgbox").fadeTo(200,0.1,function() //start fading the messagebox
{
//add message and change the class of the box and start fading
$(this).html('Sorry, only letters (a-z), numbers (0-9), and periods (.) are allowed.').addClass('messageboxerror').fadeTo(900,1);
});
}
else if(data=='no') // if username not avaiable
{
$("#msgbox").fadeTo(200,0.1,function() //start fading the messagebox
{
//add message and change the class of the box and start fading
$(this).html('User id already exists').addClass('messageboxerror').fadeTo(900,1);
});
}
else
{
$("#msgbox").fadeTo(200,0.1,function() //start fading the messagebox
{
//add message and change the class of the box and start fading
$(this).html('User id available to register').addClass('messageboxok').fadeTo(900,1);
});
}
});
});
});
</script>
<input type="text" id="username" name="username"/><span id="msgbox" style="display:none"></span>
and script for your user_availability.php will be:
<?php
include'includes/config.php';
//value got from the get method
$user_name = trim($_POST['user_name']);
if($user_name == ''){
echo "empty";
}elseif(preg_match('/[\'^£$%&*()}{@#~?><>,|=_+¬-]/', $user_name)){
echo "invalid";
}else{
$select = mysql_query("SELECT user_id FROM staff");
$i=0;
//this varible contains the array of existing users
while($fetch = mysql_fetch_array($select)){
$existing_users[$i] = $fetch['user_id'];
$i++;
}
//checking weather user exists or not in $existing_users array
if (in_array($user_name, $existing_users))
{
//user name is not availble
echo "no";
}
else
{
//user name is available
echo "yes";
}
}
?>
I tried to add for / and \ but not succeeded.
You can also do it by using javascript & code will be:
<!-- Check special characters in username start -->
<script language="javascript" type="text/javascript">
function check(e) {
var keynum
var keychar
var numcheck
// For Internet Explorer
if (window.event) {
keynum = e.keyCode;
}
// For Netscape/Firefox/Opera
else if (e.which) {
keynum = e.which;
}
keychar = String.fromCharCode(keynum);
//List of special characters you want to restrict
if (keychar == "'" || keychar == "`" || keychar =="!" || keychar =="@" || keychar =="#" || keychar =="$" || keychar =="%" || keychar =="^" || keychar =="&" || keychar =="*" || keychar =="(" || keychar ==")" || keychar =="-" || keychar =="_" || keychar =="+" || keychar =="=" || keychar =="/" || keychar =="~" || keychar =="<" || keychar ==">" || keychar =="," || keychar ==";" || keychar ==":" || keychar =="|" || keychar =="?" || keychar =="{" || keychar =="}" || keychar =="[" || keychar =="]" || keychar =="¬" || keychar =="£" || keychar =='"' || keychar =="\\") {
return false;
} else {
return true;
}
}
</script>
<!-- Check special characters in username end -->
<!-- in your form -->
User id : <input type="text" id="txtname" name="txtname" onkeypress="return check(event)"/>
Here are several ways. Choose most convenient.
Configure your web server to redirect all non-secure requests to https. Example of a nginx config:
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name example.com www.example.com;
return 301 https://example.com$request_uri;
}
Set your environment variable APP_URL
using https:
APP_URL=https://example.com
Use helper secure_url() (Laravel5.6)
Add following string to AppServiceProvider::boot() method (for version 5.4+):
\Illuminate\Support\Facades\URL::forceScheme('https');
Update:
Implicitly setting scheme for route group (Laravel5.6):
Route::group(['scheme' => 'https'], function () {
// Route::get(...)->name(...);
});
I am making a blog website on github pages. I got an idea to embbed comments in the end of every blog page. I understand how firebase get and gives you data.
I have tested many times with project and even using console. I am totally disagree the saying vlit is vulnerable.

This is primarily a long comment supporting and building on the answer by @mattway
Given:
Some of the other proposed solutions on this page advocate hitting the datastore on every request. If you hit the main datastore to validate every authentication request, then I see less reason to use JWT instead of other established token authentication mechanisms. You've essentially made JWT stateful, instead of stateless if you go to the datastore each time.
(If your site receives a high volume of unauthorized requests, then JWT would deny them without hitting the datastore, which is helpful. There are probably other use cases like that.)
Given:
Truly stateless JWT authentication cannot be achieved for a typical, real world web app because stateless JWT does not have a way to provide immediate and secure support for the following important use cases:
User's account is deleted/blocked/suspended.
User's password is changed.
User's roles or permissions are changed.
User is logged out by admin.
Any other application critical data in the JWT token is changed by the site admin.
You cannot wait for token expiration in these cases. The token invalidation must occur immediately. Also, you cannot trust the client not to keep and use a copy of the old token, whether with malicious intent or not.
Therefore: I think the answer from @matt-way, #2 TokenBlackList, would be most efficient way to add the required state to JWT based authentication.
You have a blacklist that holds these tokens until their expiration date is hit. The list of tokens will be quite small compared to the total number of users, since it only has to keep blacklisted tokens until their expiration. I'd implement by putting invalidated tokens in redis, memcached or another in-memory datastore that supports setting an expiration time on a key.
You still have to make a call to your in-memory db for every authentication request that passes initial JWT auth, but you don't have to store keys for your entire set of users in there. (Which may or may not be a big deal for a given site.)
I had the same problem and solved by using Newtonsoft.Json;

After trying the options described here, I found this post from Forester in r-bloggers . I think it is a clean option to consider.
I put his code here:
From command line
$ R CMD BATCH --no-save --no-restore '--args a=1 b=c(2,5,6)' test.R test.out &
Test.R
##First read in the arguments listed at the command line
args=(commandArgs(TRUE))
##args is now a list of character vectors
## First check to see if arguments are passed.
## Then cycle through each element of the list and evaluate the expressions.
if(length(args)==0){
print("No arguments supplied.")
##supply default values
a = 1
b = c(1,1,1)
}else{
for(i in 1:length(args)){
eval(parse(text=args[[i]]))
}
}
print(a*2)
print(b*3)
In test.out
> print(a*2)
[1] 2
> print(b*3)
[1] 6 15 18
Thanks to Forester!
No, you cannot. But you can create a user defined table function.
You can do it with 2 ways. In template and in Controller. In template you can set your filtered array to another variable, then use it like you want. Here is how to do it:
<ul>
<li data-ng-repeat="user in usersList = (users | gender:filterGender)" data-ng-bind="user.name"></li>
</ul>
....
<span>{{ usersList.length | number }}</span>
If you need examples, see the AngularJs filtered count examples/demos

To access the properties of an object without knowing the names of those properties you can use a for ... in
loop:
for(key in data) {
if(data.hasOwnProperty(key)) {
var value = data[key];
//do something with value;
}
}
First of all, if table2
's idProduct is an identity, you cannot insert it explicitly until you set IDENTITY_INSERT
on that table
SET IDENTITY_INSERT table2 ON;
before the insert.
So one of two, you modify your second stored and call it with only the parameters productName
and productDescription
and then get the new ID
EXEC test2 'productName', 'productDescription'
SET @newID = SCOPE_IDENTIY()
or you already have the ID of the product and you don't need to call SCOPE_IDENTITY()
and can make the insert on table1
with that ID
You can use T-SQL to convert the date before it gets to your .NET program. This often is simpler if you don't need to do additional date conversion in your .NET program.
DECLARE @Date DATETIME = Getdate()
DECLARE @DateInt INT = CONVERT(VARCHAR(30), @Date, 112)
DECLARE @TimeInt INT = REPLACE(CONVERT(VARCHAR(30), @Date, 108), ':', '')
DECLARE @DateTimeInt BIGINT = CONVERT(VARCHAR(30), @Date, 112) + REPLACE(CONVERT(VARCHAR(30), @Date, 108), ':', '')
SELECT @Date as Date, @DateInt DateInt, @TimeInt TimeInt, @DateTimeInt DateTimeInt
Date DateInt TimeInt DateTimeInt

You should stick to the NSInteger
data types when possible. So you'd create the number like that:
NSInteger myValue = 1;
NSNumber *number = [NSNumber numberWithInteger: myValue];
Decoding works with the integerValue
method then:
NSInteger value = [number integerValue];
chmod -R 755 directory_name
works, but how would you keep new files to 755 also? The file's permissions becomes the default permission.
None of the answers demonstrate how to fetch and print the table headers. Modified the standard example from PyHive which is widely used and actively maintained.
from pyhive import hive
cursor = hive.connect(host="localhost",
port=10000,
username="shadan",
auth="KERBEROS",
kerberos_service_name="hive"
).cursor()
cursor.execute("SELECT * FROM my_dummy_table LIMIT 10")
columnList = [desc[0] for desc in cursor.description]
headerStr = ",".join(columnList)
headerTuple = tuple(headerStr.split (",")
print(headerTuple)
print(cursor.fetchone())
print(cursor.fetchall())
Android Market requires you to sign all apps you publish with a certificate, using a public/private key mechanism (the certificate is signed with your private key). This provides a layer of security that prevents, among other things, remote attackers from pushing malicious updates to your application to market (all updates must be signed with the same key).
From The App-Signing Guide of the Android Developer's site:
In general, the recommended strategy for all developers is to sign all of your applications with the same certificate, throughout the expected lifespan of your applications. There are several reasons why you should do so...
Using the same key has a few benefits - One is that it's easier to share data between applications signed with the same key. Another is that it allows multiple apps signed with the same key to run in the same process, so a developer can build more "modular" applications.

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
}
is not called every time it is called only when app is in forground
there is one override method this method is called every time , no matter what app is in foreground or in background or killed but this method is available with this firebase api version
this is the version u have to import from gradle
compile 'com.google.firebase:firebase-messaging:10.2.1'
this is the method
@Override
public void handleIntent(Intent intent) {
super.handleIntent(intent);
// you can get ur data here
//intent.getExtras().get("your_data_key")
}
with previous firebase api this method was not there so in that case fire base handle itself when app is in background .... now u have this method what ever u want to do ... u can do it here in this method .....
if you are using previous version than default activity will start in that case u can get data same way
if(getIntent().getExtras() != null && getIntent().getExtras().get("your_data_key") != null) {
String strNotificaiton = getIntent().getExtras().get("your_data_key").toString();
// do what ever u want .... }
generally this is the structure from server we get in notification
{
"notification": {
"body": "Cool offers. Get them before expiring!",
"title": "Flat 80% discount",
"icon": "appicon",
"click_action": "activity name" //optional if required.....
},
"data": {
"product_id": 11,
"product_details": "details.....",
"other_info": "......."
}
}
it's up to u how u want to give that data key or u want give notification anything u can give ....... what ever u will give here with same key u will get that data .........
there are few cases if u r not sending click action in that case when u will click on notification default activity will open , but if u want to open your specific activity when app is in background u can call your activity from this on handleIntent method because this is called every time
Order is arbitrary, but there are several ways to sort them. One of them is as following:
#First, get the files:
import glob
import re
files =glob.glob1(img_folder,'*'+output_image_format)
# if you want sort files according to the digits included in the filename, you can do as following:
files = sorted(files, key=lambda x:float(re.findall("(\d+)",x)[0]))
400 Bad request Error will be thrown due to incorrect authentication entries.
Note: Mostly due to Incorrect authentication entries due to spell changes will occur 400 Bad request.

Just like it sounds like: if the path exists, but is a file and not a directory, isdir
will return False
. Meanwhile, exists
will return True
in both cases.
All of the DISPATCH_QUEUE_PRIORITY_X queues are concurrent queues (meaning they can execute multiple tasks at once), and are FIFO in the sense that tasks within a given queue will begin executing using "first in, first out" order. This is in comparison to the main queue (from dispatch_get_main_queue()), which is a serial queue (tasks will begin executing and finish executing in the order in which they are received).
So, if you send 1000 dispatch_async() blocks to DISPATCH_QUEUE_PRIORITY_DEFAULT, those tasks will start executing in the order you sent them into the queue. Likewise for the HIGH, LOW, and BACKGROUND queues. Anything you send into any of these queues is executed in the background on alternate threads, away from your main application thread. Therefore, these queues are suitable for executing tasks such as background downloading, compression, computation, etc.
Note that the order of execution is FIFO on a per-queue basis. So if you send 1000 dispatch_async() tasks to the four different concurrent queues, evenly splitting them and sending them to BACKGROUND, LOW, DEFAULT and HIGH in order (ie you schedule the last 250 tasks on the HIGH queue), it's very likely that the first tasks you see starting will be on that HIGH queue as the system has taken your implication that those tasks need to get to the CPU as quickly as possible.
Note also that I say "will begin executing in order", but keep in mind that as concurrent queues things won't necessarily FINISH executing in order depending on length of time for each task.
As per Apple:
A concurrent dispatch queue is useful when you have multiple tasks that can run in parallel. A concurrent queue is still a queue in that it dequeues tasks in a first-in, first-out order; however, a concurrent queue may dequeue additional tasks before any previous tasks finish. The actual number of tasks executed by a concurrent queue at any given moment is variable and can change dynamically as conditions in your application change. Many factors affect the number of tasks executed by the concurrent queues, including the number of available cores, the amount of work being done by other processes, and the number and priority of tasks in other serial dispatch queues.
Basically, if you send those 1000 dispatch_async() blocks to a DEFAULT, HIGH, LOW, or BACKGROUND queue they will all start executing in the order you send them. However, shorter tasks may finish before longer ones. Reasons behind this are if there are available CPU cores or if the current queue tasks are performing computationally non-intensive work (thus making the system think it can dispatch additional tasks in parallel regardless of core count).
The level of concurrency is handled entirely by the system and is based on system load and other internally determined factors. This is the beauty of Grand Central Dispatch (the dispatch_async() system) - you just make your work units as code blocks, set a priority for them (based on the queue you choose) and let the system handle the rest.
So to answer your above question: you are partially correct. You are "asking that code" to perform concurrent tasks on a global concurrent queue at the specified priority level. The code in the block will execute in the background and any additional (similar) code will execute potentially in parallel depending on the system's assessment of available resources.
The "main" queue on the other hand (from dispatch_get_main_queue()) is a serial queue (not concurrent). Tasks sent to the main queue will always execute in order and will always finish in order. These tasks will also be executed on the UI Thread so it's suitable for updating your UI with progress messages, completion notifications, etc.

Since C++11, you may want to use either snake_case
or camelCase
for function names.
This is because to make a class work as the range-expression in a range-based for-loop, you have to define functions called begin
and end
(case-sensitive) for that class.
Consequently, using e.g. PascalCase
for function names means you have to break the naming consistency in your project if you ever need to make a class work with the range-based for.
Do a git rebase -i FAR_ENOUGH_BACK
and drop the line for the commit you don't want.

The idea of having a pop
method that both returns a value and has a side effect of updating the data stored in x
is very much a concept from object-oriented programming. So rather than defining a pop
function to operate on character vectors, we can make a reference class with a pop
method.
PopStringFactory <- setRefClass(
"PopString",
fields = list(
x = "character"
),
methods = list(
initialize = function(x)
{
x <<- x
},
pop = function(n = 1)
{
if(nchar(x) == 0)
{
warning("Nothing to pop.")
return("")
}
first <- substring(x, 1, n)
x <<- substring(x, n + 1)
first
}
)
)
x <- PopStringFactory$new("hello stackoverflow")
x
## Reference class object of class "PopString"
## Field "x":
## [1] "hello stackoverflow"
replicate(nchar(x$x), x$pop())

The ImportError message is a bit misleading because of the reference to Win32, whereas the problem was simply the opencv DLLs were not found.
This problem was solved by adding the path the opencv binaries to the Windows PATH environment variable (as an example, on my computer this path is : C:\opencv\build\bin\Release).
Ensure that you always check for the file extension in server-side to ensure that no one can upload a malicious file such as .aspx, .asp etc.
I ran across this error recently using a javascript library which changes the parameters of a function based on conditions.
You can test an object to see if it has the function. I would only do this in scenarios where you don't control what is getting passed to you.
if( param.indexOf != undefined ) {
// we have a string or other object that
// happens to have a function named indexOf
}
You can test this in your browser console:
> (3).indexOf == undefined;
true
> "".indexOf == undefined;
false

As Sai said, the shell is the child, so signals are intercepted by it -- best way I've found is to use shell=False and use shlex to split the command line:
if isinstance(command, unicode):
cmd = command.encode('utf8')
args = shlex.split(cmd)
p = subprocess.Popen(args, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
Then p.kill() and p.terminate() should work how you expect.
In this article I read that frameworks like Underscore.js use this function:
function isUndefined(obj){
return obj === void 0;
}
Here is an example that uses scipy.optimize to fit a non-linear functions like a Gaussian, even when the data is in a histogram that isn't well ranged, so that a simple mean estimate would fail. An offset constant also would cause simple normal statistics to fail ( just remove p[3] and c[3] for plain gaussian data).
from pylab import *
from numpy import loadtxt
from scipy.optimize import leastsq
fitfunc = lambda p, x: p[0]*exp(-0.5*((x-p[1])/p[2])**2)+p[3]
errfunc = lambda p, x, y: (y - fitfunc(p, x))
filename = "gaussdata.csv"
data = loadtxt(filename,skiprows=1,delimiter=',')
xdata = data[:,0]
ydata = data[:,1]
init = [1.0, 0.5, 0.5, 0.5]
out = leastsq( errfunc, init, args=(xdata, ydata))
c = out[0]
print "A exp[-0.5((x-mu)/sigma)^2] + k "
print "Parent Coefficients:"
print "1.000, 0.200, 0.300, 0.625"
print "Fit Coefficients:"
print c[0],c[1],abs(c[2]),c[3]
plot(xdata, fitfunc(c, xdata))
plot(xdata, ydata)
title(r'$A = %.3f\ \mu = %.3f\ \sigma = %.3f\ k = %.3f $' %(c[0],c[1],abs(c[2]),c[3]));
show()
Output:

It seems you're actually talking about an MVC (Model-View-Controller) pattern, where logic is separated into various "tiers". Django, as a framework, follows MVC (loosely). You have models that contain your business logic and relate directly to tables in your database, views which in effect act like the controller, handling requests and returning responses, and finally, templates which handle presentation.
Django isn't just one of these, it is a complete framework for application development and provides all the tools you need for that purpose.
Frontend vs Backend is all semantics. You could potentially build a Django app that is entirely "backend", using its built-in admin contrib package to manage the data for an entirely separate application. Or, you could use it solely for "frontend", just using its views and templates but using something else entirely to manage the data. Most usually, it's used for both. The built-in admin (the "backend"), provides an easy way to manage your data and you build apps within Django to present that data in various ways. However, if you were so inclined, you could also create your own "backend" in Django. You're not forced to use the default admin.
You may also be interested in the write-up from Sun, as part of the standard JSSE documentation:
http://docs.oracle.com/javase/8/docs/technotes/guides/security/jsse/JSSERefGuide.html#Stores
Typically, the trust store is used to store only public keys, for verification purposes, such as with X.509 authentication. For manageability purposes, it's quite common for admins or developers to simply conflate the two into a single store.
When you write x = 0

DIV is a generic block level container that can contain any other block or inline elements, including other DIV elements, whereas P is to wrap paragraphs (text).
The marked answer is completely wrong. All that does is hide the console log statement and does nothing whatsoever do address the actually issue. You can also close your eyes and it will achieve the same result.
The issue is caused by node-gyp and only that. Its purpose is to compile native extensions for certain modules such as bson.
If it fails to do so then the code will fallback to the JS version and kindly tell you so through the informative message:
Failed to load c++ bson extension, using pure JS version
I assume the question is really about how to compile the native C++ extension rather that just not seeing the message so let's address that.
In order for node-gyp to work your node-gyp must be up to date with your node and C++ compiler (that will differ based on your OS). Just as important your module must also be up to date.
First uninstall and reinstall node-gyp
npm un node-gyp -g;npm i node-gyp -g
Now you will need to fully uninstall and reinstall any node module in your app (that includes modules installed by requirements as well) that have bson. That should take care of the error. You can search for 'Release/bson' and find the culprits.
find node_modules/ -type 'f' -exec grep -H 'Release/bson' {} \;
And then uninstall and reinstall these modules.
Easier is to just redo the entire node_modules
folder:
rm -rf node_modules
npm cache clear
npm i
If you still experience issues then either 1) your module is out of date - check issue tracker in their repo or 2) you have a potential conflict - sometimes we may have a local node-gyp for example. You can run node-gyp
by itself and verify versions.

I just want to add that in some systems, even increasing the node memory limit with --max-old-space-size
, it's not enough and there is an OS error like this:
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
Aborted (core dumped)
In this case, probably is because you reached the max mmap per process.
You can check the max_map_count by running
sysctl vm.max_map_count
and increas it by running
sysctl -w vm.max_map_count=655300
and fix it to not be reset after a reboot by adding this line
vm.max_map_count=655300
in /etc/sysctl.conf
file.
Check here for more info.
A good method to analyse the error is by run the process with strace
strace node --max-old-space-size=128000 my_memory_consuming_process.js
You can do the HTML parsing but it is not at all recommended instead ask the website owners to provide web services then you can parse that information.

Here's an option that's similar, but provides another choice:
public class DefaultJsonSerializer : JsonSerializerSettings
{

NullValueHandling = NullValueHandling.Ignore;
}
}
Then, I use it like this:
JsonConvert.SerializeObject(postObj, new DefaultJsonSerializer());
The difference here is that:

Split your date into year, month, and day components then use Date:
var d = new Date(year, month, day);
d.setMonth(d.getMonth() + 8);
Date will take care of fixing the year.

As of v3.1.0, we've deprecated .pull-right on dropdown menus. To right-align a menu, use .dropdown-menu-right. Right-aligned nav components in the navbar use a mixin version of this class to automatically align the menu. To override it, use .dropdown-menu-left.
You can use the dropdown-right
class to line the right hand side of the menu up with the caret:
<li class="dropdown">
<a class="dropdown-toggle" href="#">Link</a>
<ul class="dropdown-menu dropdown-menu-right">
<li>...</li>
</ul>
</li>

The class for Bootstrap 4 are the same as Bootstrap > 3.1.0, just watch out as the rest of the surrounding markup has changed a little:
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#">
Link
</a>
<div class="dropdown-menu dropdown-menu-right">
<a class="dropdown-item" href="#">...</a>
</div>
</li>
You have two ways:
1) In Background Layer > Scaling, reduce the Resize to 1
and then in Legacy > Legacy Icon set Shape as None
2) in Background Layer > Scaling > Source Asset, you can set an image as a 1x1 pixel (or any size) transparent.png image (you've already created).
and then in Legacy > Legacy Icon set Shape as None
Note that any IDisposable implementation should follow the below pattern (IMHO). I developed this pattern based on info from several excellent .NET "gods" the .NET Framework Design Guidelines (note that MSDN does not follow this for some reason!). The .NET Framework Design Guidelines were written by Krzysztof Cwalina (CLR Architect at the time) and Brad Abrams (I believe the CLR Program Manager at the time) and Bill Wagner ([Effective C#] and [More Effective C#] (just take a look for these on Amazon.com:
Note that you should NEVER implement a Finalizer unless your class directly contains (not inherits) UNmanaged resources. Once you implement a Finalizer in a class, even if it is never called, it is guaranteed to live for an extra collection. It is automatically placed on the Finalization Queue (which runs on a single thread). Also, one very important note...all code executed within a Finalizer (should you need to implement one) MUST be thread-safe AND exception-safe! BAD things will happen otherwise...(i.e. undetermined behavior and in the case of an exception, a fatal unrecoverable application crash).
The pattern I've put together (and written a code snippet for) follows:
#region IDisposable implementation
//TODO remember to make this class inherit from IDisposable -> $className$ : IDisposable
// Default initialization for a bool is 'false'
private bool IsDisposed { get; set; }
/// <summary>
/// Implementation of Dispose according to .NET Framework Design Guidelines.
/// </summary>
/// <remarks>Do not make this method virtual.
/// A derived class should not be able to override this method.
/// </remarks>
public void Dispose()
{
Dispose( true );
// This object will be cleaned up by the Dispose method.
// Therefore, you should call GC.SupressFinalize to
// take this object off the finalization queue
// and prevent finalization code for this object
// from executing a second time.
// Always use SuppressFinalize() in case a subclass
// of this type implements a finalizer.
GC.SuppressFinalize( this );
}
/// <summary>
/// Overloaded Implementation of Dispose.
/// </summary>
/// <param name="isDisposing"></param>
/// <remarks>
/// <para><list type="bulleted">Dispose(bool isDisposing) executes in two distinct scenarios.
/// <item>If <paramref name="isDisposing"/> equals true, the method has been called directly
/// or indirectly by a user's code. Managed and unmanaged resources
/// can be disposed.</item>
/// <item>If <paramref name="isDisposing"/> equals false, the method has been called by the
/// runtime from inside the finalizer and you should not reference
/// other objects. Only unmanaged resources can be disposed.</item></list></para>
/// </remarks>
protected virtual void Dispose( bool isDisposing )
{
// TODO If you need thread safety, use a lock around these
// operations, as well as in your methods that use the resource.
try
{
if( !this.IsDisposed )
{
if( isDisposing )
{
// TODO Release all managed resources here
$end$
}
// TODO Release all unmanaged resources here
// TODO explicitly set root references to null to expressly tell the GarbageCollector
// that the resources have been disposed of and its ok to release the memory allocated for them.
}
}
finally
{
// explicitly call the base class Dispose implementation
base.Dispose( isDisposing );
this.IsDisposed = true;
}
}
//TODO Uncomment this code if this class will contain members which are UNmanaged
//
///// <summary>Finalizer for $className$</summary>
///// <remarks>This finalizer will run only if the Dispose method does not get called.
///// It gives your base class the opportunity to finalize.
///// DO NOT provide finalizers in types derived from this class.
///// All code executed within a Finalizer MUST be thread-safe!</remarks>
// ~$className$()
// {
// Dispose( false );
// }
#endregion IDisposable implementation
Here is the code for implementing IDisposable in a derived class. Note that you do not need to explicitly list inheritance from IDisposable in the definition of the derived class.
public DerivedClass : BaseClass, IDisposable (remove the IDisposable because it is inherited from BaseClass)
protected override void Dispose( bool isDisposing )
{
try
{
if ( !this.IsDisposed )
{
if ( isDisposing )
{
// Release all managed resources here
}
}
}
finally
{
// explicitly call the base class Dispose implementation
base.Dispose( isDisposing );
}
}
I've posted this implementation on my blog at: How to Properly Implement the Dispose Pattern
The init script generates a unique identifier for Android based on the name you gave it (e.g. com.acmeapp
for AcmeApp
).
You can see what name was generated by looking for the applicationId key in android/app/build.gradle
.
If you need to change that unique identifier, do it now as described below:
In the /android
folder, replace all occurrences of com.acmeapp
by com.acme.app
Then change the directory structure with the following commands:
mkdir android/app/src/main/java/com/acme
mv android/app/src/main/java/com/acmeapp android/app/src/main/java/com/acme/app
You need a folder level for each dot in the app identifier.

Change the theme of the desired Activity. This works for me:
<activity
android:name="HomeActivity"
android:screenOrientation="landscape"
android:theme="@style/Theme.AppCompat.Light"
android:windowSoftInputMode="stateHidden" />
If you don't see a certain package, you can access to a full list of ports (also unnoficials, the packages you see on the web) launching the setup.exe with -k
argument with value http://cygwinports.org/ports.gpg
(example: C:\cygwin\setup\setup-x86.exe -K http://cygwinports.org/ports.gpg
).
Doing so, you can choose a lot of extra packages, also extra versions of cURL (compat one). I do that to get Apache, cUrl, php5, php5-curl and some others :)
I don't know if apt-cyg can get those extra packages.
There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.
This can not have a variable:
create function Func() returns table
as
return
select 10 as ColName
You have to do like this instead:
create function Func()
returns @T table(ColName int)
as
begin
declare @Var int
set @Var = 10
insert into @T(ColName) values (@Var)
return
end
You can achieve this with DateTime
extension, which will also work for number of minutes that is larger than one day (>= 1440
):
$minutes = 250;
$zero = new DateTime('@0');
$offset = new DateTime('@' . $minutes * 60);
$diff = $zero->diff($offset);
echo $diff->format('%a Days, %h Hours, %i Minutes');
I forgot to tell a bug when i use I use req.session.email = req.param('email'), the server error says cannot sett property email of undefined.
The reason of this error is a wrong order of app.use. You must configure express in this order:
app.use(express.cookieParser());
app.use(express.session({ secret: sessionVal }));
app.use(app.route);
You need to perform two steps -
git remote remove origin
git remote add origin [email protected]:NuggetAI/nugget.git
Notice the Git URL is a SSH URL and not an HTTPS URL... Which you can select from here:
We're using Jira 6.2 and I use this query:
updatedDate > startOfDay(-1d) AND updatedDate < endOfDay(-1)
to return all of the issues that were updated from the previous day. You can combine with whichever queries you want to return the appropriate issues for the previous day.
This should work:
ax1.plot(xtr, color='r', label='HHZ 1')
ax1.legend(loc="upper right")
ax2.plot(xtr, color='r', label='HHN')
ax2.legend(loc="upper right")
ax3.plot(xtr, color='r', label='HHE')
ax3.legend(loc="upper right")
Remember.. inherits is case sensitive for C# (not so for vb.net)
Found that out the hard way.
You need to add a reference to System.Windows.Forms.dll, then use the System.Windows.Forms.FolderBrowserDialog
class.
Adding using WinForms = System.Windows.Forms;
will be helpful.
It usually happens when Allow Nulls option is unchecked.
Solution:
Try these steps. It worked for me.
Typically one would use one (or more) image tags, maybe in combination with setting div background images in css to act as the submit button. The actual submit would be done in javascript on the click event.
A tutorial on the subject.
Try to change z-index value for .modal
and .modal-backdrop
less than .datepicker
z-index value.
You can also check with composer:
composer show laravel/framework
I found fiddling with styles.xml and activity to be too cumbersome hence created a common utility method which has below options set
Java
Window window = getWindow();
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
window.setStatusBarColor(Color.TRANSPARENT);
Kotlin DSL
activity.window.apply {
clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
statusBarColor = Color.TRANSPARENT
}
And that's all it took to achieve transparent status bar. Hope this helps.
In Azure Data warehouse also this occurs sometimes, because temporary tables created for a user session.. I got the same issue fixed by reconnecting the database,
Installing webpack with -g option installs webpack in a folder in
C:\Users\<.profileusername.>\AppData\Roaming\npm\node_modules
same with webpack-cli and webpack-dev-server
Outside the global node_modules a link is created for webpack to be run from commandline
C:\Users\<.profileusername.>\AppData\Roaming\npm
to make this work locally, I did the following
Problem with this approach is you'd have to maintain links for each project you have. Theres no other way since you are using the command line editor to run webpack command when installing with a -g option.
So if you had proj1, proj2 and proj3 all with their local node_modules and local webpack installed( not using -g when installing), then you'd have to create non-generic link names instead of just webpack.
example here would be to create webpack_proj1.cmd, webpack_proj2.cmd and webpack_proj3.cmd and in each cmd follow point 2 and 3 above
PS: dont forget to update your package.json with these changes or else you'll get errors as it won't find webpack command
Let me share what worked for me:
When we do "mvn clean" - we are cleaning old compiled classes please lgo to ocation "your project directroy -> target " you will find this folder is getting cleaned because that's where MVN places it's compiled artifacts
Since it's already a MAVEN project then go to your project folder and open in command prompt. And issue "mvn clean" and then "mvn test" -> "mvn test" command will place all the compiled files under proper folders and then you can run your tests through TestNG or MAVEN itself.
Make sure you set up "M2_HOME" or "MAVEN_HOME" to your env path , sometime "MAVEN_HOME" doesn't work so add "M2_HOME" as well (google it for this set up)
Above suggestions worked for me so I wanted to share, good luck
Ubuntu defaults to the OpenJDK packages. If you want to install Oracle's JDK, then you need to visit their download page, and grab the package from there.
Once you've installed the Oracle JDK, you also need to update the following (system defaults will point to OpenJDK):
export JAVA_HOME=/my/path/to/oracle/jdk
export PATH=$JAVA_HOME/bin:$PATH
If you want the Oracle JDK to be the default for your system, you will need to remove the OpenJDK packages, and update your profile environment variables.
Please install below command using command prompt.
pip install mysql-connector-python
It will not work in a browser and you might only need this in case you want to get valid JS representation for your object and not a JSON. It just runs node inline evaluation
var execSync = require('child_process').execSync
const objectToSource = (obj) =>
execSync('node -e \'console.log(JSON.parse(`' + JSON.stringify(obj) + '`))\'', { encoding: 'utf8' })
console.log(objectToSource({ a: 1 }))
It is a way of making a link do absolutely nothing when clicked (unless Javascript events are bound to it).
It is a way of running Javascript instead of following a link:
<a href="Javascript: doStuff();">link</a>
When there isn't actually javascript to run (like your example) it does nothing.
If Linux is your concern, the easiest way to append two strings:
char * append(char * string1, char * string2)
{
char * result = NULL;
asprintf(&result, "%s%s", string1, string2);
return result;
}
This won't work with MS Visual C.
Note: you have to free()
the memory returned by asprintf()
When it says users are connected, what does the query "select * from pg_stat_activity;" say? Are the other users besides yourself now connected? If so, you might have to edit your pg_hba.conf file to reject connections from other users, or shut down whatever app is accessing the pg database to be able to drop it. I have this problem on occasion in production. Set pg_hba.conf to have a two lines like this:
local all all ident
host all all 127.0.0.1/32 reject
and tell pgsql to reload or restart (i.e. either sudo /etc/init.d/postgresql reload or pg_ctl reload) and now the only way to connect to your machine is via local sockets. I'm assuming you're on linux. If not this may need to be tweaked to something other than local / ident on that first line, to something like host ... yourusername.
Now you should be able to do:
psql postgres
drop database mydatabase;
You can copy value of Parent Class to a Child class. For instance, you could use reflection if that is the case.
