I think Octave only return one value which is the first return value, in your case, 'array'.
And Octave print it as "ans".
Others, 'listp','freep' were not printed.
Because it showed up within the function.
Try this out:
[ A, B, C] = initialize( 4 )
And the 'array','listp','freep' will print as A, B and C.
from PIL import Image
image = Image.open('File.jpg')
image.show()
Strings are CharSequences, so you can just use Strings and not worry. Android is merely trying to be helpful by allowing you to also specify other CharSequence objects, like StringBuffers.
Having tested several options, I finally solved this by using
contract="IMySOAPWebService"
i.e. without the full namespace in the config. For some reason the full name didn't resolve properly
I'd like to do this way :)
const sthError = () => Promise.reject('sth error');
const test = opts => {
return (async () => {
// do sth
await sthError();
return 'ok';
})().catch(err => {
console.error(err); // error will be catched there
});
};
test().then(ret => {
console.log(ret);
});
It's similar to handling error with co
const test = opts => {
return co(function*() {
// do sth
yield sthError();
return 'ok';
}).catch(err => {
console.error(err);
});
};
If you want to convert a nested object recursively and the object may or may not contain arrays (and the arrays may contain objects or arrays, etc), then the solution gets a little more complex. This is my attempt.
I've also added some options to choose if you want to record for each object member at what depth in the main object it sits, and to choose if you want to add a label to the members that come from converted arrays.
Ideally you should test if the thing parameter really receives an object or array.
function thingToString(thing,maxDepth,recordLevel,markArrays){
//thing: object or array to be recursively serialized
//maxDepth (int or false):
// (int) how deep to go with converting objects/arrays within objs/arrays
// (false) no limit to recursive objects/arrays within objects/arrays
//recordLevel (boolean):
// true - insert "(level 1)" before transcript of members at level one (etc)
// false - just
//markArrays (boolean):
// insert text to indicate any members that came from arrays
var result = "";
if (maxDepth !== false && typeof maxDepth != 'number') {maxDepth = 3;}
var runningDepth = 0;//Keeps track how deep we're into recursion
//First prepare the function, so that it can call itself recursively
function serializeAnything(thing){
//Set path-finder values
runningDepth += 1;
if(recordLevel){result += "(level " + runningDepth + ")";}
//First convert any arrays to object so they can be processed
if (thing instanceof Array){
var realObj = {};var key;
if (markArrays) {realObj['type'] = "converted array";}
for (var i = 0;i < thing.length;i++){
if (markArrays) {key = "a" + i;} else {key = i;}
realObj[key] = thing[i];
}
thing = realObj;
console.log('converted one array to ' + typeof realObj);
console.log(thing);
}
//Then deal with it
for (var member in thing){
if (typeof thing[member] == 'object' && runningDepth < maxDepth){
serializeAnything(thing[member]);
//When a sub-object/array is serialized, it will add one to
//running depth. But when we continue to this object/array's
//next sibling, the level must go back up by one
runningDepth -= 1;
} else if (maxDepth !== false && runningDepth >= maxDepth) {
console.log('Reached bottom');
} else
if (
typeof thing[member] == "string" ||
typeof thing[member] == 'boolean' ||
typeof thing[member] == 'number'
){
result += "(" + member + ": " + thing[member] + ") ";
} else {
result += "(" + member + ": [" + typeof thing[member] + " not supported]) ";
}
}
}
//Actually kick off the serialization
serializeAnything(thing);
return result;
}

The ProGit book has a very good explanation:
Tracking Branches
Checking out a local branch from a remote branch automatically creates what is called a tracking branch. Tracking branches are local branches that have a direct relationship to a remote branch. If you’re on a tracking branch and type git push
, Git automatically knows which server and branch to push to. Also, running git pull
while on one of these branches fetches all the remote references and then automatically merges in the corresponding remote branch.
When you clone a repository, it generally automatically creates a master branch that tracks origin/master. That’s why git push
and git pull
work out of the box with no other arguments. However, you can set up other tracking branches if you wish — ones that don’t track branches on origin and don’t track the master branch. The simple case is the example you just saw, running git checkout -b [branch] [remotename]/[branch]
. If you have Git version 1.6.2 or later, you can also use the --track
shorthand:
$ git checkout --track origin/serverfix
Branch serverfix set up to track remote branch refs/remotes/origin/serverfix.
Switched to a new branch "serverfix"
To set up a local branch with a different name than the remote branch, you can easily use the first version with a different local branch name:
$ git checkout -b sf origin/serverfix
Branch sf set up to track remote branch refs/remotes/origin/serverfix.
Switched to a new branch "sf"
Now, your local branch sf
will automatically push to and pull from origin/serverfix
.
BONUS: extra git status
info
With a tracking branch, git status
will tell you whether how far behind your tracking branch you are - useful to remind you that you haven't pushed your changes yet! It looks like this:
$ git status
On branch master
Your branch is ahead of 'origin/master' by 1 commit.
(use "git push" to publish your local commits)
or
$ git status
On branch dev
Your branch and 'origin/dev' have diverged,
and have 3 and 1 different commits each, respectively.
(use "git pull" to merge the remote branch into yours)
MailKit is an Open Source cross-platform .NET mail-client library that is based on MimeKit and optimized for mobile devices. It has more and advance features better than System.Net.Mail Microsoft TNEF support via MimeKit.
Download nuget package from here.
See this example you can send mail
MimeMessage mailMessage = new MimeMessage();
mailMessage.From.Add(new MailboxAddress(senderName, [email protected]));
mailMessage.Sender = new MailboxAddress(senderName, [email protected]);
mailMessage.To.Add(new MailboxAddress(emailid, emailid));
mailMessage.Subject = subject;
mailMessage.ReplyTo.Add(new MailboxAddress(replyToAddress));
mailMessage.Subject = subject;
var builder = new BodyBuilder();
builder.TextBody = "Hello There";
try
{
using (var smtpClient = new SmtpClient())
{
smtpClient.Connect("HostName", "Port", MailKit.Security.SecureSocketOptions.None);
smtpClient.Authenticate("[email protected]", "password");
smtpClient.Send(mailMessage);
Console.WriteLine("Success");
}
}
catch (SmtpCommandException ex)
{
Console.WriteLine(ex.ToString());
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
The simple solution is to remove IndexError by incorporating the condition:
if(index<(len(li)-1))
The error 'index out of range' will not occur now as the last index will not be reached. The idea is to access the next element while iterating. On reaching the penultimate element, you can access the last element.
Use enumerate method to add index or counter to an iterable(list, tuple, etc.). Now using the index+1, we can access the next element while iterating through the list.
li = [0, 1, 2, 3]
running = True
while running:
for index, elem in enumerate(li):
if(index<(len(li)-1)):
thiselem = elem
nextelem = li[index+1]
Converting String array into stream and mapping to int is the best option available in java 8.
String[] stringArray = new String[] { "0", "1", "2" };
int[] intArray = Stream.of(stringArray).mapToInt(Integer::parseInt).toArray();
System.out.println(Arrays.toString(intArray));
I would set your larger div with position:relative;
then for your image do this:
img.classname{
position:absolute;
top:50%;
left:50%;
margin-top:-25px;
margin-left:-25px;
}
This only works because you know the dimensions of both the image and the containing div. This will also let you have other items within the containing div... where solutions like using line-height will not.
EDIT: Note... your margins are negative half of the size of the image.
@Value("${your.elements}")
private String[] elements;
yml file:
your:
elements: element1, element2, element3
Quick way to print something is:
select '** Place your mesage here' AS '** DEBUG:';
Make a
class PassMeByRef { public int theValue; }
then pass a reference to an instance of it. Note that a method that mutates state through its arguments is best avoided, especially in parallel code.
You want the :checkbox:checked
selector and map
to create an array of the values:
var checkedValues = $('input:checkbox:checked').map(function() {
return this.value;
}).get();
If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked')
, or for a common name $('input[name="Foo"]:checked')
- Update -
If you don't need IE support then you can now make the map()
call more succinct by using an arrow function:
var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();
Solved this by adding following
RewriteCond %{ENV:REDIRECT_STATUS} 200 [OR]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
There are a few steps to see the tables in an SQLite database:
List the tables in your database:

If someone says you can't because only Windows can control the non-client area, they're wrong!
That's just a half-truth because Windows lets you specify the dimensions of the non-client area. The fact is, this is possible only throughout the Windows' kernel methods, and you're in .NET, not C/C++. Anyway, don't worry! P/Invoke was meant just for such things! Indeed, the whole of the Windows Form UI and Console application Std-I/O methods are offered using system calls. Hence, you'd have only to perform the right system calls to set the non-client area up, as documented in MSDN.
However, this is a really hard solution I came up with a lot of time ago. Luckily, as of .NET 4.5, you can use the WindowChrome
class to adjust the non-client area like you want. Here you can get to start with.
In order to make things simpler and cleaner, I'll redirect you here, a guide to change the window border dimensions to whatever you want. By setting it to 0, you'll be able to implement your custom window border in place of the system's one.
I'm sorry for not posting a clear example, but later I will for sure.
You need to download the Native Development Kit.
I just looked into my code. In one application, I just add the controls, but without specifying the index, and when done, I just loop through the row styles and set the size type to AutoSize. So just adding them without specifying the indices seems to add the rows as intended (provided the GrowStyle is set to AddRows).
In another application, I clear the controls and set the RowCount property to the needed value. This does not add the RowStyles. Then I add my controls, this time specifying the indices, and add a new RowStyle (RowStyles.Add(new RowStyle(...)
) and this also works.
So, pick one of these methods, they both work. I remember the headaches the table layout panel caused me.
var target = document.getElementById('appBusyIndicator');
is equal to
var target = $document[0].getElementById('appBusyIndicator');
By putting an assignment of list on a variable first
myVar <- list()
it opens the possibility of hiearchial assignments by
myVar[[1]] <- list()
myVar[[2]] <- list()
and so on... so now it's possible to do
myVar[[1]][[1]] <- c(...)
myVar[[1]][[2]] <- c(...)
myVar[[1]][['subVar']] <- c(...)
and so on
it is also possible to assign directly names (instead of $)
myVar[['nameofsubvar]] <- list()
and then
myVar[['nameofsubvar]][['nameofsubsubvar']] <- c('...')
important to remember is to always use double brackets to make the system work
then to get information is simple
myVar$nameofsubvar$nameofsubsubvar
and so on...
example:
a <-list()
a[['test']] <-list()
a[['test']][['subtest']] <- c(1,2,3)
a
$test
$test$subtest
[1] 1 2 3
a[['test']][['sub2test']] <- c(3,4,5)
a
$test
$test$subtest
[1] 1 2 3
$test$sub2test
[1] 3 4 5
a nice feature of the R language in it's hiearchial definition...
I used it for a complex implementation (with more than two levels) and it works!
Edit: I just noticed that you said you had already created some commits. In that case, use git merge --squash
to make a single commit:
git checkout cleanchanges
git merge --squash master
git commit -m "nice commit comment for all my changes"
(Edit: The following answer applies if you have uncommitted changes.)
Just switch branches with git checkout cleanchanges
. If the branches refer to the same ref, then all your uncommitted changes will be preserved in your working directory when you switch.
The only time you would have a conflict is if some file in the repository is different between origin/master
and cleanchanges
. If you just created the branch, then no problem.
As always, if you're at all concerned about losing work, make a backup copy first. Git is designed to not throw away work without asking you first.
Assuming you did the normal installation with virtual box, vagrant etc.. This can happen to new people. PHP can be installed on your PC but all the modules PHP for your laravel project is on your VM So to access your VM, go to your homestead folder and type: vagrant ssh
then to go your project path and execute the php artisan migrate.
Here are a few possibilities that don't parse the output of ls
and that are 100% safe regarding files with spaces and funny symbols in their name. All of them will populate an array randf
with a list of random files. This array is easily printed with printf '%s\n' "${randf[@]}"
if needed.
This one will possibly output the same file several times, and N
needs to be known in advance. Here I chose N=42.
a=( * )
randf=( "${a[RANDOM%${#a[@]}]"{1..42}"}" )
This feature is not very well documented.
If N is not known in advance, but you really liked the previous possibility, you can use eval
. But it's evil, and you must really make sure that N
doesn't come directly from user input without being thoroughly checked!
N=42
a=( * )
eval randf=( \"\${a[RANDOM%\${#a[@]}]\"\{1..$N\}\"}\" )
I personally dislike eval
and hence this answer!
The same using a more straightforward method (a loop):
N=42
a=( * )
randf=()
for((i=0;i<N;++i)); do
randf+=( "${a[RANDOM%${#a[@]}]}" )
done
If you don't want to possibly have several times the same file:
N=42
a=( * )
randf=()
for((i=0;i<N && ${#a[@]};++i)); do
((j=RANDOM%${#a[@]}))
randf+=( "${a[j]}" )
a=( "${a[@]:0:j}" "${a[@]:j+1}" )
done
Note. This is a late answer to an old post, but the accepted answer links to an external page that shows terrible bash practice, and the other answer is not much better as it also parses the output of ls
. A comment to the accepted answer points to an excellent answer by Lhunath which obviously shows good practice, but doesn't exactly answer the OP.
var list = {
"you": 100,
"me": 75,
"foo": 116,

};
function sortAssocObject(list) {
var sortable = [];
for (var key in list) {
sortable.push([key, list[key]]);
}
// [["you",100],["me",75],["foo",116],["bar",15]]
sortable.sort(function(a, b) {
return (a[1] < b[1] ? -1 : (a[1] > b[1] ? 1 : 0));
});
// [["bar",15],["me",75],["you",100],["foo",116]]
var orderedList = {};
for (var idx in sortable) {
orderedList[sortable[idx][0]] = sortable[idx][1];
}
return orderedList;
}
sortAssocObject(list);
// {bar: 15, me: 75, you: 100, foo: 116}
You can do:
super.alphaMethod1();
Note, that super
is a reference to the parent, but super() is it's constructor.
Those documents are outdated. I'm guessing the 1.6 in the URL is for Docker 1.6, not Compose 1.6. Check out the correct syntax here: https://docs.docker.com/compose/compose-file/#network_mode. You are looking for network_mode
when using the v2 YAML format.
The +
operator returns the numeric representation of the object. So in your particular case, it would appear to be predicating the if on whether or not d
is a non-zero number.
OP's question is: does something like following exists, if not then why
print(p) for p in myList # doesn't work, OP's intuition
answer is, it does exist which is:
[p for p in myList] #works perfectly
Basically, use []
for list comprehension and get rid of print
to avoiding printing None
. To see why print
prints None
see this
Up to C#5 (-VS2013) you have to call a function/method for it. Either a "normal" function such as String.Format
or an overload of the + operator.
string str = "Hello " + name; // This calls an overload of operator +.
In C#6 (VS2015) string interpolation has been introduced (as described by other answers).
CDATA tells the browser to display the text as is and not to render it as an HTML.
1) Open base profile :
open ~/.bash_profile
2) Add below line in base profile :

Save and close base profile.
For me 27.0.3 working great.

You can cheat! Say your div is 20px high, place the div at the top of the next container and set

It may not be semantically clean but does scale with responsive designs
I used RestAssured most of the time to parse rest service response and test the services. Apart from Rest Assured, I used below libraries too to communicate with Resful services.

You should provide output file name after -o
option. In your case runexp.o
is treated as output file name, not input object file and thus your main

Please try adding the double quotes git commit -m "initial commit". This will solve your problem.
Finally with the latest release of Android Studio 4 and his new Emulator update 10/23/2019 it become easier. Start your emulator and go to emulator parameters ... > in "Routes" tab you can choose two points on the map from/to and start a new route with an adjustable playback speed that can go to more than 1000km/h!
suppose you're posting a html form with this:
<input type="text" name="username">
If using raw cgi:
import cgi
form = cgi.FieldStorage()
print form["username"]
If using Django, Pylons, Flask or Pyramid:
print request.GET['username'] # for GET form method
print request.POST['username'] # for POST form method
Using Turbogears, Cherrypy:
from cherrypy import request
print request.params['username']
form = web.input()
print form.username
print request.form['username']
If using Cherrypy or Turbogears, you can also define your handler function taking a parameter directly:
def index(self, username):
print username
class SomeHandler(webapp2.RequestHandler):
def post(self):
name = self.request.get('username') # this will get the value from the field named username
self.response.write(name) # this will write on the document
So you really will have to choose one of those frameworks.
You might want to check that library
**org.eclipse.equinox.launcher_(version).dist.jar**
and
**plugins/org.eclipse.equinox.launcher.gtk.linux.x86_(version).dist**
exists on your system.
Make sure that the version of libraries mentioned in eclipse.ini and the version that exists on your system is same. Usually after upgrade this mismatch occurs and eclipse fails to locate the required jar. Please take a look at this blog post here
Suppose you are running a test python file named request.py
In request.py, you write
import request
so this also most likely a circular import.
Solution:
Just change your test file to another name such as aaa.py
, other than request.py
.
Do not use names that are already used by other libs.

To find which library is being used you could run
$ /sbin/ldconfig -p | grep stdc++
libstdc++.so.6 (libc6) => /usr/lib/libstdc++.so.6
The list of compatible versions for libstdc++ version 3.4.0 and above is provided by
$ strings /usr/lib/libstdc++.so.6 | grep LIBCXX
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
...
For earlier versions the symbol GLIBCPP
is defined.
The date stamp of the library is defined in a macro __GLIBCXX__
or __GLIBCPP__
depending on the version:
// libdatestamp.cxx
#include <cstdio>
int main(int argc, char* argv[]){
#ifdef __GLIBCPP__
std::printf("GLIBCPP: %d\n",__GLIBCPP__);

The table of datestamps of libstdc++ versions is listed in the documentation:
Actually, in Bootstrap 4.0.0-Beta (as of October 2017) the input element isn't referenced by input[type="text"], all Bootstrap 4 properties for the input element are actually form based.
So it's using the .form-control:focus styles. The appropriate code for the "on focus" highlighting of an input element is the following:
.form-control:focus {
color: #495057;
background-color: #fff;
border-color: #80bdff;
outline: none;
}
Pretty easy to implement, just change the border-color property.
There are several scenarios to consider. First of all, you need to check the type of your object. You can simply call GetType() for this. If the type does not implement IDynamicMetaObjectProvider, then you can use reflection same as for any other object. Something like:
var propertyInfo = test.GetType().GetProperties();
However, for IDynamicMetaObjectProvider implementations, the simple reflection doesn't work. Basically, you need to know more about this object. If it is ExpandoObject (which is one of the IDynamicMetaObjectProvider implementations), you can use the answer provided by itowlson. ExpandoObject stores its properties in a dictionary and you can simply cast your dynamic object to a dictionary.
If it's DynamicObject (another IDynamicMetaObjectProvider implementation), then you need to use whatever methods this DynamicObject exposes. DynamicObject isn't required to actually "store" its list of properties anywhere. For example, it might do something like this (I'm reusing an example from my blog post):
public class SampleObject : DynamicObject
{
public override bool TryGetMember(GetMemberBinder binder, out object result)
{
result = binder.Name;
return true;
}
}
In this case, whenever you try to access a property (with any given name), the object simply returns the name of the property as a string.
dynamic obj = new SampleObject();
Console.WriteLine(obj.SampleProperty);
//Prints "SampleProperty".
So, you don't have anything to reflect over - this object doesn't have any properties, and at the same time all valid property names will work.
I'd say for IDynamicMetaObjectProvider implementations, you need to filter on known implementations where you can get a list of properties, such as ExpandoObject, and ignore (or throw an exception) for the rest.

I can't find any other built-in way of doing case-insensitive comparison: The python cook-book recipe uses lower().
However you have to be careful when using lower for comparisons because of the Turkish I problem. Unfortunately Python's handling for Turkish Is is not good. i is converted to I, but I is not converted to i. I is converted to i, but i is not converted to I.

Tanuki changed license of jsw some time ago, if I was to begin a project, I would use Yet Another Java Service Wrapper, http://yajsw.sourceforge.net/ that is more or less an open source implementation that mimics JWS, and then builds on it and improves it even further.
EDIT: I have been using YAJSW for several years on several platorms (Windows, several linuxes...) and it is great, development is ongoing.
From the documentation:
requests
can also ignore verifying the SSL certificate if you setverify
to False.>>> requests.get('https://kennethreitz.com', verify=False) <Response [200]>
If you're using a third-party module and want to disable the checks, here's a context manager that monkey patches requests
and changes it so that verify=False
is the default and suppresses the warning.
import warnings
import contextlib
import requests
from urllib3.exceptions import InsecureRequestWarning
old_merge_environment_settings = requests.Session.merge_environment_settings
@contextlib.contextmanager
def no_ssl_verification():
opened_adapters = set()
def merge_environment_settings(self, url, proxies, stream, verify, cert):
# Verification happens only once per connection so we need to close
# all the opened adapters once we're done. Otherwise, the effects of
# verify=False persist beyond the end of this context manager.
opened_adapters.add(self.get_adapter(url))
settings = old_merge_environment_settings(self, url, proxies, stream, verify, cert)
settings['verify'] = False
return settings
requests.Session.merge_environment_settings = merge_environment_settings
try:
with warnings.catch_warnings():
warnings.simplefilter('ignore', InsecureRequestWarning)
yield
finally:
requests.Session.merge_environment_settings = old_merge_environment_settings
for adapter in opened_adapters:
try:
adapter.close()
except:
pass
Here's how you use it:
with no_ssl_verification():
requests.get('https://wrong.host.badssl.com/')
print('It works')
requests.get('https://wrong.host.badssl.com/', verify=True)
print('Even if you try to force it to')
requests.get('https://wrong.host.badssl.com/', verify=False)
print('It resets back')
session = requests.Session()
session.verify = True
with no_ssl_verification():
session.get('https://wrong.host.badssl.com/', verify=True)
print('Works even here')
try:
requests.get('https://wrong.host.badssl.com/')
except requests.exceptions.SSLError:
print('It breaks')
try:
session.get('https://wrong.host.badssl.com/')
except requests.exceptions.SSLError:
print('It breaks here again')
Note that this code closes all open adapters that handled a patched request once you leave the context manager. This is because requests maintains a per-session connection pool and certificate validation happens only once per connection so unexpected things like this will happen:
>>> import requests
>>> session = requests.Session()
>>> session.get('https://wrong.host.badssl.com/', verify=False)

I'm not sure what the rest of your Javascript looks like, so I won't be able to tell if there is any interference. But .hover()
works just fine as an event with .on()
.
$("#foo").on("hover", function() {
// disco
});
If you want to be able to utilize its events, use the returned object from the event:
$("#foo").on("hover", function(e) {
if(e.type == "mouseenter") {
console.log("over");
}
else if (e.type == "mouseleave") {
console.log("out");
}
});
You may find this thread useful. And here's a google code project exemplifying this (it P/Invokes into setupapi.dll
).
$('.toggle img').data('block', 'something');
$('.toggle img').attr('src', 'something.jpg');
Use jQuery.data and jQuery.attr.
I'm showing them to you separately for the sake of understanding.
I think we can you use verbatim tag, as in this tag we use any of the HTML tags
The Main problem is in unable to start the service when app closed, android OS(In Some OS) will kill the service for Resource Optimization, If you are not able to restart the service then call a alarm manger to start the receiver like this,Here is the entire code, This code will keep alive ur service.
Manifest is,
<service
android:name=".BackgroundService"
android:description="@string/app_name"
android:enabled="true"
android:label="Notification" />
<receiver android:name="AlarmReceiver">
<intent-filter>
<action android:name="REFRESH_THIS" />
</intent-filter>
</receiver>
IN Main Activty start alarm manger in this way,
String alarm = Context.ALARM_SERVICE;
AlarmManager am = (AlarmManager) getSystemService(alarm);
Intent intent = new Intent("REFRESH_THIS");
PendingIntent pi = PendingIntent.getBroadcast(this, 123456789, intent, 0);
int type = AlarmManager.RTC_WAKEUP;
long interval = 1000 * 50;
am.setInexactRepeating(type, System.currentTimeMillis(), interval, pi);
this will call reciver and reciver is,
public class AlarmReceiver extends BroadcastReceiver {
Context context;
@Override
public void onReceive(Context context, Intent intent) {
this.context = context;
System.out.println("Alarma Reciver Called");
if (isMyServiceRunning(this.context, BackgroundService.class)) {
System.out.println("alredy running no need to start again");
} else {
Intent background = new Intent(context, BackgroundService.class);
context.startService(background);
}
}
public static boolean isMyServiceRunning(Context context, Class<?> serviceClass) {
ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningServiceInfo> services = activityManager.getRunningServices(Integer.MAX_VALUE);
if (services != null) {
for (int i = 0; i < services.size(); i++) {
if ((serviceClass.getName()).equals(services.get(i).service.getClassName()) && services.get(i).pid != 0) {
return true;
}
}
}
return false;
}
}
And this Alaram reciver calls once when android app is opened and when app is closed.SO the service is like this,
public class BackgroundService extends Service {
private String LOG_TAG = null;
@Override
public void onCreate() {
super.onCreate();
LOG_TAG = "app_name";
Log.i(LOG_TAG, "service created");
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.i(LOG_TAG, "In onStartCommand");
//ur actual code
return START_STICKY;
}
@Override
public IBinder onBind(Intent intent) {
// Wont be called as service is not bound
Log.i(LOG_TAG, "In onBind");
return null;
}
@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
@Override
public void onTaskRemoved(Intent rootIntent) {
super.onTaskRemoved(rootIntent);
Log.i(LOG_TAG, "In onTaskRemoved");
}
@Override
public void onDestroy() {
super.onDestroy();
Log.i(LOG_TAG, "In onDestroyed");
}
}
You'll want to use JavaScript's Array splice
method:
var tag_story = [1,3,56,6,8,90],
id_tag = 90,
position = tag_story.indexOf(id_tag);
if ( ~position ) tag_story.splice(position, 1);
P.S. For an explanation of that cool ~
tilde shortcut, see this post:
Using a ~
tilde with indexOf
to check for the existence of an item in an array.
Note: IE < 9 does not support .indexOf()
on arrays. If you want to make sure your code works in IE, you should use jQuery's $.inArray()
:
var tag_story = [1,3,56,6,8,90],
id_tag = 90,
position = $.inArray(id_tag, tag_story);
if ( ~position ) tag_story.splice(position, 1);
If you want to support IE < 9 but don't already have jQuery on the page, there's no need to use it just for $.inArray
. You can use this polyfill instead.
You need a root node

(eg: div,footer,table) Right click -> Edit as HTML
Then you can copy and paster wherever you need...
that's all enjoy your coding.....
An array should obviously be "traversed" right-to-left to avoid unneccessary copying of values back and forth.
If you have unlimited memory, you can allocate a bit array for sizeof(type-of-element-in-array) / 8
bytes to have each bit signify whether you've already encountered corresponding value or not.
If you don't, I can't think of anything better than traversing an array and comparing each value with values that follow it and then if duplicate is found, remove these values altogether. This is somewhere near O(n^2) (or O((n^2-n)/2)).
IBM has an article on kinda close subject.
This is how you can reverse-engineer the exception type from within catch(...)
should you need to (may be useful when catching unknown from a third party library) with GCC:
#include <iostream>
#include <exception>
#include <typeinfo>
#include <stdexcept>
int main()
{
try {
throw ...; // throw something
}
catch(...)
{
std::exception_ptr p = std::current_exception();
std::clog <<(p ? p.__cxa_exception_type()->name() : "null") << std::endl;
}
return 1;
}
and if you can afford using Boost you can make your catch section even simpler (on the outside) and potentially cross-platform
catch (...)
{
std::clog << boost::current_exception_diagnostic_information() << std::endl;
}
getAttribute() -> It fetches the text that contains one of any attribute in the HTML tag. Suppose there is an HTML tag like
<input name="Name Locator" value="selenium">Hello</input>
Now getAttribute() fetches the data of the attribute of 'value', which is "Selenium".
Returns:
The attribute's current value or null if the value is not set.
driver.findElement(By.name("Name Locator")).getAttribute("value") //
The field value is retrieved by the getAttribute("value") Selenium WebDriver predefined method and assigned to the String object.
getText() -> delivers the innerText of a WebElement. Get the visible (i.e. not hidden by CSS) innerText of this element, including sub-elements, without any leading or trailing whitespace.
Returns:
The innerText of this element.
driver.findElement(By.name("Name Locator")).getText();
'Hello' will appear
I was recently working with moment.js, following did the trick..
function getDateRange(startDate, endDate, dateFormat) {
var dates = [],
end = moment(endDate),
diff = endDate.diff(startDate, 'days');
if(!startDate.isValid() || !endDate.isValid() || diff <= 0) {
return;
}
for(var i = 0; i < diff; i++) {
dates.push(end.subtract(1,'d').format(dateFormat));
}
return dates;
};
console.log(getDateRange(startDate, endDate, dateFormat));
Result would be:
["09/03/2015", "10/03/2015", "11/03/2015", "12/03/2015", "13/03/2015", "14/03/2015", "15/03/2015", "16/03/2015", "17/03/2015", "18/03/2015"]
You can also use Gson to convert an object to a JSONObject and pass it on bundle. For me was the most elegant way I found to do this. I haven't tested how it affects performance.
In Initial Activity
Intent activity = new Intent(MyActivity.this,NextActivity.class);
activity.putExtra("myObject", new Gson().toJson(myobject));
startActivity(activity);
In Next Activity
String jsonMyObject;
Bundle extras = getIntent().getExtras();
if (extras != null) {
jsonMyObject = extras.getString("myObject");
}
MyObject myObject = new Gson().fromJson(jsonMyObject, MyObject.class);
This is the easiest way:
php -f /home/your_username/public_html/script.php
And if you want to log the script output to a file, add this to the end of the command:
>> /home/your_username/logs/someFile.txt 2>&1
about 3 years ago i needed cctv. I found zoneminder, tried to edit it to my liking, but found i was fixing it more than editing it.
Not to mention mp4 recording feature isn't actually part of the master branch (which is kind of lol, since its a cctv program and its already been about 3 years or more since it was suggested). Its literally just adapting the ffmpeg command lol.
So i found the solution!
If you want something done right, do it yourself.

I tried a few things, favouring pattern matching as a way of avoiding casting but ran into trouble with type erasure on the collection types.
The main problem seems to be that the complete type of the parse result mirrors the structure of the JSON data and is either cumbersome or impossible to fully state. I guess that is why Any is used to truncate the type definitions. Using Any leads to the need for casting.
I've hacked something below which is concise but is extremely specific to the JSON data implied by the code in the question. Something more general would be more satisfactory but I'm not sure if it would be very elegant.
implicit def any2string(a: Any) = a.toString
implicit def any2boolean(a: Any) = a.asInstanceOf[Boolean]
implicit def any2double(a: Any) = a.asInstanceOf[Double]
case class Language(name: String, isActive: Boolean, completeness: Double)
val languages = JSON.parseFull(jstr) match {
case Some(x) => {
val m = x.asInstanceOf[Map[String, List[Map[String, Any]]]]
m("languages") map {l => Language(l("name"), l("isActive"), l("completeness"))}
}
case None => Nil
}
languages foreach {println}
Your code works fine, except that the barplot is ordered from low to high. When you want to order the bars from high to low, you will have to add a -
sign before value
:
ggplot(corr.m, aes(x = reorder(miRNA, -value), y = value, fill = variable)) +
geom_bar(stat = "identity")
which gives:
Used data:
corr.m <- structure(list(miRNA = structure(c(5L, 2L, 3L, 6L, 1L, 4L), .Label = c("mmu-miR-139-5p", "mmu-miR-1983", "mmu-miR-301a-3p", "mmu-miR-5097", "mmu-miR-532-3p", "mmu-miR-96-5p"), class = "factor"),
variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = "pos", class = "factor"),
value = c(7L, 75L, 70L, 5L, 10L, 47L)),

I came across this question looking for a way to open an Explorer window from PowerShell and also select a file. I'm adding this answer in case others come across it for the same reason.
To launch Explorer and select a file, use Invoke-Expression
:
Invoke-Expression "explorer '/select,$filePath'"
There are probably other ways to do this, but this worked for me.
The best practice is to ajax load the order information when click tr tag, and render the information html in $('#orderDetails') like this:
$.get('the_get_order_info_url', { order_id: the_id_var }, function(data){
$('#orderDetails').html(data);
}, 'script')
Alternatively, you can add class for each td that contains the order info, and use jQuery method $('.class').html(html_string) to insert specific order info into your #orderDetails BEFORE you show the modal, like:
<% @restaurant.orders.each do |order| %>
<!-- you should add more class and id attr to help control the DOM -->
<tr id="order_<%= order.id %>" onclick="orderModal(<%= order.id %>);">
<td class="order_id"><%= order.id %></td>
<td class="customer_id"><%= order.customer_id %></td>
<td class="status"><%= order.status %></td>
</tr>
<% end %>
js:
function orderModal(order_id){
var tr = $('#order_' + order_id);
// get the current info in html table
var customer_id = tr.find('.customer_id');
var status = tr.find('.status');
// U should work on lines here:
var info_to_insert = "order: " + order_id + ", customer: " + customer_id + " and status : " + status + ".";
$('#orderDetails').html(info_to_insert);
$('#orderModal').modal({
keyboard: true,
backdrop: "static"
});
};
That's it. But I strongly recommend you to learn sth about ajax on Rails. It's pretty cool and efficient.

I have the Problem with debugged processes with gdb in Code::Blocks. As soon it is hanging while accidentally stepping into instructions out of scope of your sources (as libs without sources or system functions) you cannot quit the debugging neither from Code::Blocks nor from Task-Manager.
I think it is an error in the implementation of gdb in Code::Blocks, but could also be in gdb ;)
My Solution:
taskkill /F /IM process.exe /T
This shows the PID of the parent process. Now kill the parent:
taskkill /PID yyyy
Both are gone.
Done.
This error may occur when you are adding an app in INSTALLED_APPS
in the settings.py
file but you do not have that app installed in your computer. You have two solution:
Install

which you may have created for your project.
I just found something in the TypeScript language specification, it's fairly easy. I was pretty close.
the syntax is the following:
public myCallback: (name: type) => returntype;
In my example, it would be
class CallbackTest
{
public myCallback: () => void;
public doWork(): void
{
//doing some work...
this.myCallback(); //calling callback
}
}
If anyone's having trouble with this (as I was), you can get the postback code for a button by adding the UseSubmitBehavior="false" attribute to it. If you examine the rendered source of the button, you'll see the exact javascript you need to execute. In my case it was using the name of the button rather than the id.
This question has got 91,000 views so perhaps many people are looking for a more generic solution to the issue in the title "error converting varchar to INT"
If you are on SQL Server 2012+ one way of handling this invalid data is to use TRY_CAST
SELECT TRY_CAST (userID AS INT)
FROM audit
On previous versions you could use
SELECT CASE
WHEN ISNUMERIC(RTRIM(userID) + '.0e0') = 1
AND LEN(userID) <= 11
THEN CAST(userID AS INT)
END
FROM audit
Both return NULL
if the value cannot be cast.
In the specific case that you have in your question with known bad values I would use the following however.
CAST(REPLACE(userID COLLATE Latin1_General_Bin, CHAR(0),'') AS INT)
Trying to replace the null character is often problematic except if using a binary collation.
Here is a good example on how to do a command if a file does or does not exist:
if exist C:\myprogram\sync\data.handler echo Now Exiting && Exit
if not exist C:\myprogram\html\data.sql Exit
We will take those three files and put it in a temporary place. After deleting the folder, it will restore those three files.
xcopy "test" "C:\temp"
xcopy "test2" "C:\temp"
del C:\myprogram\sync\
xcopy "C:\temp" "test"
xcopy "C:\temp" "test2"
del "c:\temp"
Use the XCOPY command:
xcopy "C:\myprogram\html\data.sql" /c /d /h /e /i /y "C:\myprogram\sync\"
I will explain what the /c /d /h /e /i /y
means:
/C Continues copying even if errors occur.
/D:m-d-y Copies files changed on or after the specified date.
If no date is given, copies only those files whose
source time is newer than the destination time.
/H Copies hidden and system files also.
/E Copies directories and subdirectories, including empty ones.
Same as /S /E. May be used to modify /T.
/T Creates directory structure, but does not copy files. Does not
include empty directories or subdirectories. /T /E includes
/I If destination does not exist and copying more than one file,
assumes that destination must be a directory.
/Y Suppresses prompting to confirm you want to overwrite an
existing destination file.

Call other batch file with option sync.bat myprogram.ini.
I am not sure what you mean by this, but if you just want to open both of these files you just put the path of the file like
Path/sync.bat
Path/myprogram.ini
If it was in the Bash environment it was easy for me, but I do not know how to test if a file or folder exists and if it is a file or folder.
You are using a batch file. You mentioned earlier you have to create a .bat file to use this:
I have to create a .BAT file that does this:
You will need wrapper classes:
public class SomeIntInfo
{
[XmlAttribute]
public int Value { get; set; }
}
public class SomeStringInfo
{
[XmlAttribute]
public string Value { get; set; }
}
public class SomeModel
{
[XmlElement("SomeStringElementName")]
public SomeStringInfo SomeString { get; set; }
[XmlElement("SomeInfoElementName")]
public SomeIntInfo SomeInfo { get; set; }
}
or a more generic approach if you prefer:
public class SomeInfo<T>
{
[XmlAttribute]
public T Value { get; set; }
}
public class SomeModel
{
[XmlElement("SomeStringElementName")]
public SomeInfo<string> SomeString { get; set; }
[XmlElement("SomeInfoElementName")]
public SomeInfo<int> SomeInfo { get; set; }
}
And then:
class Program
{
static void Main()
{
var model = new SomeModel
{
SomeString = new SomeInfo<string> { Value = "testData" },
SomeInfo = new SomeInfo<int> { Value = 5 }
};
var serializer = new XmlSerializer(model.GetType());
serializer.Serialize(Console.Out, model);
}
}
will produce:
<?xml version="1.0" encoding="ibm850"?>
<SomeModel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<SomeInfoElementName Value="5" />
</SomeModel>
Try this:
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
ComboBox cmb = (ComboBox)sender;
int selectedIndex = cmb.SelectedIndex;
int selectedValue = (int)cmb.SelectedValue;
ComboboxItem selectedCar = (ComboboxItem)cmb.SelectedItem;
MessageBox.Show(String.Format("Index: [{0}] CarName={1}; Value={2}", selectedIndex, selectedCar.Text, selecteVal));

The registry is a no-go. You're not sure whether the user which uses your application, has sufficient rights to write to the registry.
You can use the app.config
file to save application-level settings (that are the same for each user who uses your application).
I would store user-specific settings in an XML file, which would be saved in Isolated Storage or in the SpecialFolder.ApplicationData directory.
Next to that, as from .NET 2.0, it is possible to store values back to the app.config
file.
What's the first part of your Subversion repository URL?
I can't guarantee the first four since it's possible to reconfigure everything to use different ports, of if you go through a proxy of some sort.
If you're using a VPN, you may have to configure your VPN client to reroute these to their correct ports. A lot of places don't configure their correctly VPNs to do this type of proxying. It's either because they have some sort of anal-retentive IT person who's being overly security conscious, or because they simply don't know any better. Even worse, they'll give you a client where this stuff can't be reconfigured.
The only way around that is to log into a local machine over the VPN, and then do everything from that system.
SERVER_IP="$(ip addr show ens160 | grep 'inet ' | cut -f2 | awk '{ print $2}')"

This is covered in the PHP documentation for booleans and type comparison tables.
When converting to boolean, the following values are considered FALSE:
FALSE
itself0
(zero)0.0
(zero)'0'
NULL
(including unset variables)Every other value is considered TRUE.
It's possible that the modules are installed, but your PHP.ini still points to an old directory.
Check the contents of /usr/lib/php/extensions. In mine, there were two directories: no-debug-non-zts-20060613 and no-debug-non-zts-20060613. Around line 428 of your php.ini, change:
extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20060613"
to
extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20090626"
Then restart apache. This should resolve the issue.
arr = [str(r) for r in arr]
This basically converts all your elements in string. Hence removes the encoding. Hence the u which represents encoding gets removed Will do the work easily and efficiently
Fragment fr = new Fragment_class();
FragmentManager fm = getFragmentManager();
FragmentTransaction fragmentTransaction = fm.beginTransaction();
fragmentTransaction.add(R.id.viewpagerId, fr);
fragmentTransaction.commit();
Just to be precise, R.id.viewpagerId
is cretaed in your current class layout, upon calling, the new fragment automatically gets infiltrated.

A few comments:
analog=True
in the call to butter
, and you should use scipy.signal.freqz
(not freqs
) to generate the frequency response.Here's my modified version of your script, followed by the plot that it generates.
import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt
def butter_lowpass(cutoff, fs, order=5):
nyq = 0.5 * fs
normal_cutoff = cutoff / nyq
b, a = butter(order, normal_cutoff, btype='low', analog=False)
return b, a
def butter_lowpass_filter(data, cutoff, fs, order=5):
b, a = butter_lowpass(cutoff, fs, order=order)
y = lfilter(b, a, data)
return y
# Filter requirements.
order = 6
fs = 30.0 # sample rate, Hz
cutoff = 3.667 # desired cutoff frequency of the filter, Hz
# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)
# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)

# "Noisy" data. We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

If you have multiple sections, here's how to get the last row in the last section (Swift 3):
func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
if let visibleRows = tableView.indexPathsForVisibleRows, let lastRow = visibleRows.last?.row, let lastSection = visibleRows.map({$0.section}).last {
if indexPath.row == lastRow && indexPath.section == lastSection {
// Finished loading visible rows
}
}
}
Note: As the original asker implied, if you are setting up two databases on the same machine you probably want to make two schemas instead - in that case you don't need anything special to query across them.
postgres_fdw
Use postgres_fdw
(foreign data wrapper) to connect to tables in any Postgres database - local or remote.
Note that there are foreign data wrappers for other popular data sources. At this time, only postgres_fdw
and file_fdw
are part of the official Postgres distribution.
Versions this old are no longer supported, but if you need to do this in a pre-2013 Postgres installation, there is a function called dblink
.
I've never used it, but it is maintained and distributed with the rest of PostgreSQL. If you're using the version of PostgreSQL that came with your Linux distro, you might need to install a package called postgresql-contrib.

Add the css for .card
.card {

float: none; /* Added */
margin-bottom: 10px; /* Added */
}
here is the pen
UPDATE:
You can use the class .mx-auto
available in bootstrap 4 to center cards.
You could always use "%p" in order to display 8 bit hex numbers.
int main (void)
{
uint8_t a;
uint32_t b;
a=15;
b=a<<28;
printf("%p", b);
return 0;

As far as concerns, you want to delete rows in story_category
that do not exist in category
.
Here is your original query to identify the rows to delete:
SELECT *
FROM story_category
WHERE category_id NOT IN (
SELECT DISTINCT category.id
FROM category INNER JOIN
story_category ON category_id=category.id
);
Combining NOT IN
with a subquery that JOIN
s the original table seems unecessarily convoluted. This can be expressed in a more straight-forward manner with not exists
and a correlated subquery:
select sc.*
from story_category sc
where not exists (select 1 from category c where c.id = sc.category_id);
Now it is easy to turn this to a delete
statement:
delete from story_category
where not exists (select 1 from category c where c.id = story_category.category_id);
This quer would run on any MySQL version, as well as in most other databases that I know.
-- set-up
create table story_category(category_id int);
create table category (id int);
insert into story_category values (1), (2), (3), (4), (5);
insert into category values (4), (5), (6), (7);
-- your original query to identify offending rows
SELECT *
FROM story_category
WHERE category_id NOT IN (
SELECT DISTINCT category.id
FROM category INNER JOIN
story_category ON category_id=category.id);
| category_id | | ----------: | | 1 | | 2 | | 3 |
-- a functionally-equivalent, simpler query for this
select sc.*
from story_category sc
where not exists (select 1 from category c where c.id = sc.category_id)
| category_id | | ----------: | | 1 | | 2 | | 3 |
-- the delete query
delete from story_category
where not exists (select 1 from category c where c.id = story_category.category_id);
-- outcome
select * from story_category;
| category_id | | ----------: | | 4 | | 5 |
To get proper (translatable) messages, currently using SF 2.6.3, here is my final function (as none of above's seem to work anymore):
private function getErrorMessages(\Symfony\Component\Form\Form $form) {
$errors = array();
foreach ($form->getErrors(true, false) as $error) {
// My personnal need was to get translatable messages
// $errors[] = $this->trans($error->current()->getMessage());
$errors[] = $error->current()->getMessage();
}
return $errors;
}
as the Form::getErrors() method now returns an instance of FormErrorIterator, unless you switch the second argument ($flatten) to true. (It will then return a FormError instance, and you will have to call the getMessage() method directly, without the current() method:
private function getErrorMessages(\Symfony\Component\Form\Form $form) {
$errors = array();
foreach ($form->getErrors(true, true) as $error) {
// My personnal need was to get translatable messages
// $errors[] = $this->trans($error->getMessage());
$errors[] = $error->getMessage();
}
return $errors;
}
)
The most important thing is actually to set the first argument to true in order to get the errors. Leaving the second argument ($flatten) to his default value (true) will return FormError instances, while it will return FormErrorIterator instances when set to false.

Here is a simple 3 step ES6 implementation using function binding in the parent constructor. This is the first way the official react tutorial recommends (there is also public class fields syntax not covered here). You can find all of this information here https://reactjs.org/docs/handling-events.html
Binding Parent Functions so Children Can Call Them (And pass data up to the parent! :D )
Parent Function
handleFilterApply(filterVals){}
Parent Constructor
this.handleFilterApply = this.handleFilterApply.bind(this);
Prop Passed to Child
onApplyClick = {this.handleFilterApply}
Child Event Call
onClick = {() => {props.onApplyClick(filterVals)}
Use GSON for converting POJO to JSONObject. Refer here.
For converting JSONObject to POJO, just call the setter method in the POJO and assign the values directly from the JSONObject.
My requirements were a bit stricter:
My initial thought was to substitute our clunky Path class for a case insensitive unicode subclass - but:

Implicit vs explicit is still a problem, but once dust settles, renaming of attributes/variables to start with ci (and a big fat doc comment explaining that ci stands for case insensitive) I think is a perfect solution - as readers of the code must be fully aware that we are dealing with case insensitive underlying data structures. This will hopefully fix some hard to reproduce bugs, which I suspect boil down to case sensitivity.
Comments/corrections welcome :)
Many of the solutions have focused on complicating things.
Using withRouter is a really long solution for something as simple as a button that links to somewhere else in the App.
If you are going for S.P.A. (single page application), the easiest answer I have found is to use with the button's equivalent className.
This ensures you are maintaining shared state / context without reloading your entire app as is done with
import { NavLink } from 'react-router-dom'; // 14.6K (gzipped: 5.2 K)
// Where link.{something} is the imported data
<NavLink className={`bx--btn bx--btn--primary ${link.className}`} to={link.href} activeClassName={'active'}>
{link.label}
</NavLink>
// Simplified version:
<NavLink className={'bx--btn bx--btn--primary'} to={'/myLocalPath'}>
Button without using withRouter
</NavLink>
The 2nd call to Enable-Migrations is failing because the Configuration.cs file already exists. If you rename that class and file, you should be able to run that 2nd Enable-Migrations, which will create another Configuration.cs.
You will then need to specify which configuration you want to use when updating the databases.
Update-Database -ConfigurationTypeName MyRenamedConfiguration
I had the same problem and it turned out that my image names included special characters (e.g. château.jpg), which could not bet handled by cv2.imread
. My solution was to make a temporary copy of the file, renaming it e.g. temp.jpg, which could be loaded by cv2.imread
without any problems.
Note: I did not check the performance of shutil.copy2
vice versa other options. So probably there is a better/faster solution to make a temporary copy.
import shutil, sys, os, dlib, glob, cv2
for f in glob.glob(os.path.join(myfolder_path, "*.jpg")):
shutil.copy2(f, myfolder_path + 'temp.jpg')
img = cv2.imread(myfolder_path + 'temp.jpg')
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
os.remove(myfolder_path + 'temp.jpg')
If there are only few files with special characters, renaming can also be done as an exeption, e.g.
for f in glob.glob(os.path.join(myfolder_path, "*.jpg")):
try:
img = cv2.imread(f)
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
except:
shutil.copy2(f, myfolder_path + 'temp.jpg')
img = cv2.imread(myfolder_path + 'temp.jpg')
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
os.remove(myfolder_path + 'temp.jpg')
You can use the scrollbar-width
rule. You can scrollbar-width: none;
to hide the scrollbar in Firefox and still be able to scroll freely.
body {
scrollbar-width: none;
}
Use NameValuedCollection.
Good starting point is here. Straight from the link.
System.Collections.Specialized.NameValueCollection myCollection
= new System.Collections.Specialized.NameValueCollection();
myCollection.Add(“Arcane”, “http://arcanecode.com”);
myCollection.Add(“PWOP”, “http://dotnetrocks.com”);
myCollection.Add(“PWOP”, “http://dnrtv.com”);
myCollection.Add(“PWOP”, “http://www.hanselminutes.com”);
myCollection.Add(“TWIT”, “http://www.twit.tv”);
myCollection.Add(“TWIT”, “http://www.twit.tv/SN”);
There is a shorter way of doing this now:
exports.someValue = function(req, res, next) {
//query with mongoose
dbSchemas.SomeValue.find({}, 'name', function(err, someValue){
if(err) return next(err);
res.send(someValue);
});
//this eliminates the .select() and .exec() methods
};
In case you want most of the Schema fields
and want to omit only a few, you can prefix the field name
with a -
. For ex "-name"
in the second argument will not include name
field in the doc whereas the example given here will have only the name
field in the returned docs.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//set up notitle
requestWindowFeature(Window.FEATURE_NO_TITLE);
//set up full screen
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
}
For a Fragment you can simply add
getActivity().onBackPressed();
to your code
First use this Namespace:
using System.Drawing;
Add this anywhere on your form:
listBox.DrawMode = DrawMode.OwnerDrawFixed;
listBox.DrawItem += listBox_DrawItem;
Here is the Event Handler:
private void listBox_DrawItem(object sender, DrawItemEventArgs e)
{
e.DrawBackground();
Graphics g = e.Graphics;
g.FillRectangle(new SolidBrush(Color.White), e.Bounds);
ListBox lb = (ListBox)sender;
g.DrawString(lb.Items[e.Index].ToString(), e.Font, new SolidBrush(Color.Black), new PointF(e.Bounds.X, e.Bounds.Y));
e.DrawFocusRectangle();
}
Style the td
and th
instead
td, th {
border: 1px solid black;
}
And also to make it so there is no spacing between cells use:
table {
border-collapse: collapse;
}
(also note, you have border-style: none;
which should be border-style: solid;
)
See an example here: http://jsfiddle.net/KbjNr/
It depends on what sender address you are talking about. The sender address visble in the recipients mailprogramm is extracted from the "From:" Header. which can probably easily be set from your program.
If you are talking about the SMTP envelope sender address, you can pass the -f argument to the sendmail binary. Depending on the server configuration you may not be allowed to do that with the apache user.
from the sendmail manpage :
-f <address>
This option sets the address of the envelope sender of a
locally-generated message (also known as the return path).
The option can normally be used only by a trusted user, but
untrusted_set_sender can be set to allow untrusted users to
use it. [...]
From Oracle 18c
you could use Inline External Tables:
Inline external tables enable the runtime definition of an external table as part of a SQL statement, without creating the external table as persistent object in the data dictionary.
With inline external tables, the same syntax that is used to create an external table with a CREATE TABLE statement can be used in a SELECT statement at runtime. Specify inline external tables in the FROM clause of a query block. Queries that include inline external tables can also include regular tables for joins, aggregation, and so on.

with
statementDifferentiating between exceptions that occur in a with
statement is tricky because they can originate in different places. Exceptions can be raised from either of the following places (or functions called therein):
ContextManager.__init__
ContextManager.__enter__
with
ContextManager.__exit__
For more details see the documentation about Context Manager Types.
If we want to distinguish between these different cases, just wrapping the with
into a try .. except
is not sufficient. Consider the following example (using ValueError
as an example but of course it could be substituted with any other exception type):
try:
with ContextManager():
BLOCK
except ValueError as err:
print(err)
Here the except
will catch exceptions originating in all of the four different places and thus does not allow to distinguish between them. If we move the instantiation of the context manager object outside the with
, we can distinguish between __init__
and BLOCK / __enter__ / __exit__
:
try:
mgr = ContextManager()
except ValueError as err:
print('__init__ raised:', err)
else:
try:
with mgr:
try:
BLOCK
except TypeError: # catching another type (which we want to handle here)
pass
except ValueError as err:
# At this point we still cannot distinguish between exceptions raised from
# __enter__, BLOCK, __exit__ (also BLOCK since we didn't catch ValueError in the body)
pass
Effectively this just helped with the __init__
part but we can add an extra sentinel variable to check whether the body of the with
started to execute (i.e. differentiating between __enter__
and the others):
try:
mgr = ContextManager() # __init__ could raise
except ValueError as err:
print('__init__ raised:', err)
else:
try:
entered_body = False
with mgr:
entered_body = True # __enter__ did not raise at this point
try:
BLOCK
except TypeError: # catching another type (which we want to handle here)
pass
except ValueError as err:
if not entered_body:
print('__enter__ raised:', err)
else:
# At this point we know the exception came either from BLOCK or from __exit__
pass
The tricky part is to differentiate between exceptions originating from BLOCK
and __exit__
because an exception that escapes the body of the with
will be passed to __exit__
which can decide how to handle it (see the docs). If however __exit__
raises itself, the original exception will be replaced by the new one. To deal with these cases we can add a general except
clause in the body of the with
to store any potential exception that would have otherwise escaped unnoticed and compare it with the one caught in the outermost except
later on - if they are the same this means the origin was BLOCK
or otherwise it was __exit__
(in case __exit__
suppresses the exception by returning a true value the outermost except
will simply not be executed).
try:
mgr = ContextManager() # __init__ could raise
except ValueError as err:
print('__init__ raised:', err)
else:
entered_body = exc_escaped_from_body = False
try:
with mgr:
entered_body = True # __enter__ did not raise at this point
try:
BLOCK
except TypeError: # catching another type (which we want to handle here)
pass
except Exception as err: # this exception would normally escape without notice
# we store this exception to check in the outer `except` clause
# whether it is the same (otherwise it comes from __exit__)
exc_escaped_from_body = err
raise # re-raise since we didn't intend to handle it, just needed to store it
except ValueError as err:
if not entered_body:
print('__enter__ raised:', err)
elif err is exc_escaped_from_body:
print('BLOCK raised:', err)
else:
print('__exit__ raised:', err)
PEP 343 -- The "with" Statement specifies an equivalent "non-with" version of the with
statement. Here we can readily wrap the various parts with try ... except
and thus differentiate between the different potential error sources:
import sys
try:
mgr = ContextManager()
except ValueError as err:
print('__init__ raised:', err)
else:
try:
value = type(mgr).__enter__(mgr)
except ValueError as err:
print('__enter__ raised:', err)
else:
exit = type(mgr).__exit__
exc = True
try:
try:
BLOCK
except TypeError:
pass
except:
exc = False
try:
exit_val = exit(mgr, *sys.exc_info())
except ValueError as err:
print('__exit__ raised:', err)
else:
if not exit_val:
raise
except ValueError as err:
print('BLOCK raised:', err)
finally:
if exc:
try:
exit(mgr, None, None, None)
except ValueError as err:
print('__exit__ raised:', err)
The need for such special exception handling should be quite rare and normally wrapping the whole with
in a try ... except
block will be sufficient. Especially if the various error sources are indicated by different (custom) exception types (the context managers need to be designed accordingly) we can readily distinguish between them. For example:
try:
with ContextManager():
BLOCK
except InitError: # raised from __init__
...
except AcquireResourceError: # raised from __enter__
...

-H/--header <header>
(HTTP) Extra header to use when getting a web page. You may specify
any number of extra headers. Note that if you should add a custom
header that has the same name as one of the internal ones curl would
use, your externally set header will be used instead of the internal
one. This allows you to make even trickier stuff than curl would
normally do. You should not replace internally set headers without
knowing perfectly well what you're doing. Remove an internal header
by giving a replacement without content on the right side of the
colon, as in: -H "Host:".
curl will make sure that each header you add/replace get sent with
the proper end of line marker, you should thus not add that as a
part of the header content: do not add newlines or carriage returns
they will only mess things up for you.
See also the -A/--user-agent and -e/--referer options.
This option can be used multiple times to add/replace/remove multi-
ple headers.
curl --header "X-MyHeader: 123" www.google.com
You can see the request that curl sent by adding the -v
option.
I checked all the solutions on this post and the post that @kenorb referenced above, and I did not find any solution that worked for me.
I am using Git 1.9.5 Preview on Windows 7 with the following configuration: - Run Git from the Windows Command Prompt - Checkout Windows-style, commit Unix-style line endings
I used the 'Git Bash' console for everything... And all was well until I tried to install the SSH keys. GitHub's documentation says to do the following (don't run these commands until you finish reading the post):
Ensure ssh-agent is enabled:
If you are using Git Bash, turn on ssh-agent:If you are using another terminal prompt, such as msysgit, turn on ssh-agent:# start the ssh-agent in the background ssh-agent -s # Agent pid 59566
# start the ssh-agent in the background eval $(ssh-agent -s) # Agent pid 59566
Now of course I missed the fact that you were supposed to do one or the other. So, I ran these commands multiple times because the later ssh-add
command was failing, so I returned to this step, and continued to retry over and over.
This results in 1 Windows 'ssh-agent' process being created every single time you run these commands (notice the new PID every time you enter those commands?)
So, Ctrl
+Alt
+Del
and hit End Process
to stop each 'ssh-agent.exe' process.
Now that all the messed up stuff from the failed attempts is cleaned up, I will tell you how to get it working...
Start the 'ssh-agent.exe' process
eval $(ssh-agent -s)
And install the SSH keys
ssh-add "C:\Users\MyName\.ssh\id_rsa"
* Adjust the path above with your username, and make sure that the location of the* /.ssh directory is in the correct place. I think you choose this location during the Git installation? Maybe not...
The part I was doing wrong before I figured this out was I was not using quotes around the 'ssh-add' location. The above is how it needs to be entered on Windows.
Try these:
sudo modprobe vboxnetadp
sudo modprobe vboxnetflt
sudo modprobe vboxdrv
I am sure there is a direct way (calling functions on your extension directly, or by using the JS classes for extensions), but an indirect method (until something better comes along):
Have your Chrome extension look for a specific DIV or other element on your page, with a very specific ID.
For example:
<div id="ExtensionCheck_JamesEggersAwesomeExtension"></div>
Do a getElementById
and set the innerHTML
to the version number of your extension or something. You can then read the contents of that client-side.
Again though, you should use a direct method if there is one available.
EDIT: Direct method found!!
Use the connection methods found here: https://developer.chrome.com/extensions/extension#global-events
Untested, but you should be able to do...
var myPort=chrome.extension.connect('yourextensionid_qwerqweroijwefoijwef', some_object_to_send_on_connect);
If access modifier of base class member function is protected OR public, you can do call member function of base class from derived class. Call to the base class non-virtual and virtual member function from derived member function can be made. Please refer the program.
#include<iostream>
using namespace std;
class Parent
{
protected:
virtual void fun(int i)
{
cout<<"Parent::fun functionality write here"<<endl;
}
void fun1(int i)
{
cout<<"Parent::fun1 functionality write here"<<endl;
}
void fun2()
{
cout<<"Parent::fun3 functionality write here"<<endl;
}
};
class Child:public Parent
{
public:
virtual void fun(int i)
{
cout<<"Child::fun partial functionality write here"<<endl;
Parent::fun(++i);
Parent::fun2();
}
void fun1(int i)
{
cout<<"Child::fun1 partial functionality write here"<<endl;
Parent::fun1(++i);
}
};
int main()
{
Child d1;
d1.fun(1);
d1.fun1(2);
return 0;
}
Output:

in python 2.6 use string enclosed inside quotation " and apostrophe ' marks. Also a change single / to double //. Your working example will look like this:
import os
os.system("'C://Documents and Settings//flow_model//flow.exe'")
Also You can use any parameters if Your program ingest them.
os.system('C://"Program Files (x86)"//Maxima-gcl-5.37.3//gnuplot//bin//gnuplot -e "plot [-10:10] sin(x),atan(x),cos(atan(x)); pause mouse"')
finally You can use string variable, as an example is plotting using gnuplot directly from python:
this_program='C://"Program Files (x86)"//Maxima-gcl-5.37.3//gnuplot//bin//gnuplot'
this_par='-e "set polar; plot [-2*pi:2*pi] [-3:3] [-3:3] t*sin(t); pause -1"'
os.system(this_program+" "+this_par)
Sounds to me like at least one of those tables has defined UserID
as a uniqueidentifier
, not an int
. Did you check the data in each table? What does SELECT TOP 1 UserID FROM
each table yield? An int
or a GUID
?
EDIT
I think you have built a procedure based on all tables that contain a column named UserID. I think you should not have included the aspnet_Membership
table in your script, since it's not really one of "your" tables.
If you meant to design your tables around the aspnet_Membership
database, then why are the rest of the columns int
when that table clearly uses a uniqueidentifier
for the UserID
column?

To do this in Windows CLI environment, the best way I can find is to use the mode command and parse the output.
function getTerminalSizeOnWindows() {
$output = array();
$size = array('width'=>0,'height'=>0);
exec('mode',$output);
foreach($output as $line) {
$matches = array();
$w = preg_match('/^\s*columns\:?\s*(\d+)\s*$/i',$line,$matches);
if($w) {
$size['width'] = intval($matches[1]);
} else {
$h = preg_match('/^\s*lines\:?\s*(\d+)\s*$/i',$line,$matches);
if($h) {
$size['height'] = intval($matches[1]);
}
}
if($size['width'] AND $size['height']) {
break;
}
}
return $size;
}
I hope it's useful!
NOTE: The height returned is the number of lines in the buffer, it is not the number of lines that are visible within the window. Any better options out there?

Disclaimer: This approach is a naive illustration of Ruby's capabilities, and not a production-grade solution for replacing strings in files. It's prone to various failure scenarios, such as data loss in case of a crash, interrupt, or disk being full. This code is not fit for anything beyond a quick one-off script where all the data is backed up. For that reason, do NOT copy this code into your programs.
Here's a quick short way to do it.
file_names = ['foo.txt', 'bar.txt']
file_names.each do |file_name|
text = File.read(file_name)
new_contents = text.gsub(/search_regexp/, "replacement string")
# To merely print the contents of the file, use:
puts new_contents
# To write changes to the file, use:
File.open(file_name, "w") {|file| file.puts new_contents }
end
Lock is a questionable idea in JS which is intended to be threadless and not needing concurrency protection. You're looking to combine calls on deferred execution. The pattern I follow for this is the use of callbacks. Something like this:
var functionLock = false;
var functionCallbacks = [];
var lockingFunction = function (callback) {
if (functionLock) {
functionCallbacks.push(callback);
} else {
$.longRunning(function(response) {
while(functionCallbacks.length){
var thisCallback = functionCallbacks.pop();
thisCallback(response);
}
});
}
}
You can also implement this using DOM event listeners or a pubsub solution.
Sometimes, the methods in the other answers don't work. In my case, I'm generating a signature with my RSA private key and the result is NSData. I found that this seems to work:
Objective-C
NSData *signature;
NSString *signatureString = [signature base64EncodedStringWithOptions:0];
Swift
let signatureString = signature.base64EncodedStringWithOptions(nil)
For anyone wondering how to call pip list
from a Python program you can use the following:
import pip
pip.main(['list]) # this will print all the packages
Try using this code for v3:
gMap = new google.maps.Map(document.getElementById('map'));
gMap.setZoom(13); // This will trigger a zoom_changed on the map
gMap.setCenter(new google.maps.LatLng(37.4419, -122.1419));
gMap.setMapTypeId(google.maps.MapTypeId.ROADMAP);
you can retrieve value like this
string str = (string)(range.Cells[row, col] as Excel.Range).Value2 ;
select entire used range
Excel.Range range = xlWorkSheet.UsedRange;

The data.table
package has its IDate

JoiningDate = c('12/31/09', '10/28/09', '05/06/10'),
AmtPaid = c(1000, 100, 200)
)
require(data.table)
dt[ , JoiningDate := as.IDate(JoiningDate, '%m/%d/%y') ]
Have a look at the System.Diagnostics
namespace. Lots of goodies in there!
System.Diagnostics.StackTrace t = new System.Diagnostics.StackTrace();
This is really good to have a poke around in to learn whats going on under the hood.
I'd recommend that you have a look into logging solutions (Such as NLog, log4net or the Microsoft patterns and practices Enterprise Library) which may achieve your purposes and then some. Good luck mate!
Might be useful. I needed the action in the constructor of the controller, and it appears at this point of the MVC lifecycle, this
hasn't initialized, and ControllerContext = null
. Instead of delving into the MVC lifecycle and finding the appropriate function name to override, I just found the action in the RequestContext.RouteData
.
But in order to do so, as with any HttpContext
related uses in the constructor, you have to specify the full namespace, because this.HttpContext
also hasn't been initialized. Luckily, it appears System.Web.HttpContext.Current
is static.
// controller constructor
public MyController() {
// grab action from RequestContext
string action = System.Web.HttpContext.Current.Request.RequestContext.RouteData.GetRequiredString("action");
// grab session (another example of using System.Web.HttpContext static reference)
string sessionTest = System.Web.HttpContext.Current.Session["test"] as string
}
NOTE: likely not the most supported way to access all properties in HttpContext, but for RequestContext and Session it appears to work fine in my application.
I've been frustrated for long by Windows code page issues, and the C programs portability and localisation issues they cause. The previous posts have detailed the issues at length, so I'm not going to add anything in this respect.
To make a long story short, eventually I ended up writing my own UTF-8 compatibility library layer over the Visual C++ standard C library. Basically this library ensures that a standard C program works right, in any code page, using UTF-8 internally.
This library, called MsvcLibX, is available as open source at https://github.com/JFLarvoire/SysToolsLib. Main features:
More details in the MsvcLibX README on GitHub, including how to build the library and use it in your own programs.
The release section in the above GitHub repository provides several programs using this MsvcLibX library, that will show its capabilities. Ex: Try my which.exe tool with directories with non-ASCII names in the PATH, searching for programs with non-ASCII names, and changing code pages.
Another useful tool there is the conv.exe program. This program can easily convert a data stream from any code page to any other. Its default is input in the Windows code page, and output in the current console code page. This allows to correctly view data generated by Windows GUI apps (ex: Notepad) in a command console, with a simple command like: type WINFILE.txt | conv
This MsvcLibX library is by no means complete, and contributions for improving it are welcome!
You could subscribe for the .click event for the links and change the contents of the div using the .html
method:
$('.click').click(function() {
// get the contents of the link that was clicked
var linkText = $(this).text();
// replace the contents of the div with the link text
$('#content-container').html(linkText);
// cancel the default action of the link by returning false
return false;
});
Note however that if you replace the contents of this div the click handler that you have assigned will be destroyed. If you intend to inject some new DOM elements inside the div for which you need to attach event handlers, this attachments should be performed inside the .click handler after inserting the new contents. If the original selector of the event is preserved you may also take a look at the .delegate
method to attach the handler.
$(document).ready(function () {
$('.dates li a').click(function (e) {
$('.dates li a').removeClass('active');
var $parent = $(this);
if (!$parent.hasClass('active')) {
$parent.addClass('active');
}
e.preventDefault();
});
});
Be careful with permissions, it is problably you don't have some of them. You can see it in settings -> apps -> name of the application -> permissions -> active if not.
Backtick quotes with a space inside and two spaces to follow. Repeat as needed for more lines:

it's presumably a chrome and/or jquery bug
I used conda-forge to install pillow version 5, and that seemed to work for me:
conda install --channel conda-forge pillow=5
the normal conda install pillow did NOT work for me.
For best useful I create this function:
func dateFormatting() -> String {
let date = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "EEEE dd MMMM yyyy - HH:mm:ss"//"EE" to get short style
let mydt = dateFormatter.string(from: date).capitalized
return "\(mydt)"
}
You simply call it wherever you want like this:
print("Date = \(self.dateFormatting())")
this is the Output:
Date = Monday 15 October 2018 - 17:26:29
if want only the time simply change :
dateFormatter.dateFormat = "HH:mm:ss"
and this is the output:
Date = 17:27:30
and that's it...

Check here for how to add the activedirectory module if not there by default. This can be done on any machine and then it will allow you to access your active directory "domain control" server.
To prevent problems with stale links (I have found MSDN blogs to disappear for no reason in the past), in essence for Windows 7 you need to download and install Remote Server Administration Tools (KB958830). After installing do the following steps:
Windows server editions should already be OK but if not you need to download and install the Active Directory Management Gateway Service. If any of these links should stop working, you should still be able search for the KB article or download names and find them.
You could do something like this:

\item foo
\item bar
\item baz

Less space:
\begin{itemize}
\setlength{\itemsep}{1pt}
\setlength{\parskip}{0pt}
\setlength{\parsep}{0pt}
\item foo
\item bar
\item baz
\end{itemize}
\end{document}
First, keep in mind that, in its precise definition, a module is an object in the memory of a Python interpreter, often created by reading one or more files from disk. While we may informally call a disk file such as a/b/c.py
a "module," it doesn't actually become one until it's combined with information from several other sources (such as sys.path
) to create the module object.
(Note, for example, that two modules with different names can be loaded from the same file, depending on sys.path
and other settings. This is exactly what happens with python -m my.module
followed by an import my.module
in the interpreter; there will be two module objects, __main__
and my.module
, both created from the same file on disk, my/module.py
.)
A package is a module that may have submodules (including subpackages). Not all modules can do this. As an example, create a small module hierarchy:
$ mkdir -p a/b
$ touch a/b/c.py
Ensure that there are no other files under a
. Start a Python 3.4 or later interpreter (e.g., with python3 -i
) and examine the results of the following statements:
import a
a ? <module 'a' (namespace)>
a.b ? AttributeError: module 'a' has no attribute 'b'
import a.b.c
a.b ? <module 'a.b' (namespace)>
a.b.c ? <module 'a.b.c' from '/home/cjs/a/b/c.py'>
Modules a
and a.b
are packages (in fact, a certain kind of package called a "namespace package," though we wont' worry about that here). However, module a.b.c
is not a package. We can demonstrate this by adding another file, a/b.py
to the directory structure above and starting a fresh interpreter:
import a.b.c
? ImportError: No module named 'a.b.c'; 'a.b' is not a package
import a.b
a ? <module 'a' (namespace)>
a.__path__ ? _NamespacePath(['/.../a'])
a.b ? <module 'a.b' from '/home/cjs/tmp/a/b.py'>
a.b.__path__ ? AttributeError: 'module' object has no attribute '__path__'
Python ensures that all parent modules are loaded before a child module is loaded. Above it finds that a/
is a directory, and so creates a namespace package a
, and that a/b.py
is a Python source file which it loads and uses to create a (non-package) module a.b
. At this point you cannot have a module a.b.c
because a.b
is not a package, and thus cannot have submodules.
You can also see here that the package module a
has a __path__
attribute (packages must have this) but the non-package module a.b
does not.

Gartner in Oct 2006 states that testing typically consumes between 10% and 35% of work on a system integration project. I assume that it applies to the waterfall method. This is quite a wide range - but there are many dependencies on the amount of customisations to a standard product and the number of systems to be integrated.
Usually this refers the the ability for an object of type A to behave like an object of type B. In object oriented programming this is usually achieve by inheritance. Some wikipedia links to read more:

Clearing the cache means that new shares of this webpage will show the new content which is provided in the OG tags. But only if the URL that you are working on has less than 50 interactions (likes + shares). It will also not affect old links to this webpage which have already been posted on Facebook. Only when sharing the URL on Facebook again will the way that Facebook shows the link be updated.
catandmouse's answer is correct but you can also make Facebook clear the OG (OpenGraph) cache by sending a post request to graph.facebook.com (works for both http and https as of the writing of this answer). You do not need an access token.
A post request to graph.facebook.com may look as follows:
POST / HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Host: graph.facebook.com
Content-Length: 63
Accept-Encoding: gzip
User-Agent: Mojolicious (Perl)
id=<url_encoded_url>&scrape=true
In Perl, you can use the following code where the library Mojo::UserAgent is used to send and receive HTTP requests:
sub _clear_og_cache_on_facebook {
my $fburl = "http://graph.facebook.com";
my $ua = Mojo::UserAgent->new;
my $clearurl = <the url you want Facebook to forget>;
my $post_body = {id => $clearurl, scrape => 'true'};
my $res = $ua->post($fburl => form => $post_body)->res;
my $code = $res->code;
unless ($code eq '200') {
Log->warn("Clearing cached OG data for $clearurl failed with code $code.");
}

New, expanded answer to an old, commonly asked question...
minOccurs
and maxOccurs
default to 1
.<xsd:element name="A"/>
means A
is required and must appear exactly once.
<xsd:element name="A" minOccurs="0"/>
means A
is optional and may appear at most once.
<xsd:element name="A" maxOccurs="unbounded"/>
means A
is required and may repeat an unlimited number of times.
<xsd:element name="A" minOccurs="0" maxOccurs="unbounded"/>
means A
is optional and may repeat an unlimited number of times.
In general, an element is required to appear when the value of minOccurs is 1 or more. The maximum number of times an element may appear is determined by the value of a maxOccurs attribute in its declaration. This value may be a positive integer such as 41, or the term unbounded to indicate there is no maximum number of occurrences. The default value for both the minOccurs and the maxOccurs attributes is 1. Thus, when an element such as comment is declared without a maxOccurs attribute, the element may not occur more than once. Be sure that if you specify a value for only the minOccurs attribute, it is less than or equal to the default value of maxOccurs, i.e. it is 0 or 1. Similarly, if you specify a value for only the maxOccurs attribute, it must be greater than or equal to the default value of minOccurs, i.e. 1 or more. If both attributes are omitted, the element must appear exactly once.

From the description of material design specs:
Grid Lists are an alternative to standard list views. Grid lists are distinct from grids used for layouts and other visual presentations.
If you are looking for a much lightweight Grid component library, I'm using React-Flexbox-Grid, the implementation of flexboxgrid.css
in React.
On top of that, React-Flexbox-Grid played nicely with both material-ui, and react-toolbox (the alternative material design implementation).
My requirement was to hide the separator between 4th and 5th cell. I achieved it by
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
if(indexPath.row == 3)
{
cell.separatorInset = UIEdgeInsetsMake(0, cell.bounds.size.width, 0, 0);
}
}
Whammo blammo (for leading spaces):
SELECT
RIGHT(space(60) + cust_name, 60),
RIGHT(space(60) + cust_address, 60)
OR (for trailing spaces)
SELECT
LEFT(cust_name + space(60), 60),
LEFT(cust_address + space(60), 60),
This might sound really simplistic...
But this will center the div inside the div, exactly in the center in relation to left and right margin or parent container, but you can adjust percentage symmetrically on left and right.
margin-right: 10%;
margin-left: 10%;
Then you can adjust % to make it as wide as you want it.
Try using the following, where n
is your variable and x is your offset (4 in this case):
LEFT(ADDRESS(1,n+x,4),1)
This will return the letter of that column (so for n=1 and x=4, it'll return A+4 = E). You can then use INDIRECT()
to reference this, as so:
COLUMNS(INDIRECT(LEFT(ADDRESS(1,n,4),1)&":"&LEFT(ADDRESS(1,n+x,4),1)))
which with n=1, x=4 becomes:
COLUMNS(INDIRECT("A"&":"&"E"))
and so:
COLUMNS(A:E)
Read the docs about built-in PHP function readfile
$file_url = 'http://www.myremoteserver.com/file.exe';
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"" . basename($file_url) . "\"");
readfile($file_url);
Also make sure to add proper content type based on your file application/zip, application/pdf etc. - but only if you do not want to trigger the save-as dialog.
for a single line implementation, you can use a lambda expression in a map
map(lambda x:MyModel.objects.get_or_create(name=x), items)
Here, lambda matches each item in items list to x and create a Database record if necessary.
You may try like this:
import java.applet.Applet;
import java.awt.*;
public class Rect1 extends Applet {
public void paint (Graphics g) {
g.drawRect (x, y, width, height); //can use either of the two//
g.fillRect (x, y, width, height);
g.setColor(color);
}
}
where x is x co-ordinate y is y cordinate color=the color you want to use eg Color.blue
if you want to use rectangle object you could do it like this:
import java.applet.Applet;
import java.awt.*;
public class Rect1 extends Applet {
public void paint (Graphics g) {
Rectangle r = new Rectangle(arg,arg1,arg2,arg3);
g.fillRect(r.getX(), r.getY(), r.getWidth(), r.getHeight());
g.setColor(color);
}
}
You can use the $.ajax()

"... current system status (current CPU, RAM, free disk space, etc.)" And "*nix and Windows platforms" can be a difficult combination to achieve.
The operating systems are fundamentally different in the way they manage these resources. Indeed, they differ in core concepts like defining what counts as system and what counts as application time.
"Free disk space"? What counts as "disk space?" All partitions of all devices? What about foreign partitions in a multi-boot environment?
I don't think there's a clear enough consensus between Windows and *nix that makes this possible. Indeed, there may not even be any consensus between the various operating systems called Windows. Is there a single Windows API that works for both XP and Vista?
For Bash, KornShell (ksh
), sh
, etc. Many of your questions are quickly answered by either:
man [function]
to get the documentation for the system you are using or usually more conveniently:
google "man function"
This may give different results for some things where Linux and Unix have modest differences.
For this question, just enter "whoami" in your shell.
To script it:
myvar=$(whoami)
Worked for me after replacing
SparkConf sparkConf = new SparkConf().setAppName("SOME APP NAME");
with
SparkConf sparkConf = new SparkConf().setAppName("SOME APP NAME").setMaster("local[2]").set("spark.executor.memory","1g");
Found this solution on some other thread on stackoverflow.
After trying several things, this worked for me:
With addresses other than 0.0.0.0
I had no success.
I had the same problem and I'm using Ubuntu 15.10.
In my case, to solve this issue, I installed the package php7.0-xml using the Synaptic package manager, which include SimpleXml. So, after restart my Apache server, my problem was solved. This package came in the Debian version and you can find it here: https://packages.debian.org/sid/php7.0-xml.
Expanding on the notes from Adel Mourad and Dan Hunex, I amended the code to provide an example that only accepts values that do not match the given value.
I also found that I didn't need the JavaScript.
I added the following class to my Models folder:
public class RequiredIfNotAttribute : ValidationAttribute, IClientValidatable
{
private String PropertyName { get; set; }
private Object InvalidValue { get; set; }
private readonly RequiredAttribute _innerAttribute;
public RequiredIfNotAttribute(String propertyName, Object invalidValue)
{
PropertyName = propertyName;
InvalidValue = invalidValue;
_innerAttribute = new RequiredAttribute();
}
protected override ValidationResult IsValid(object value, ValidationContext context)
{
var dependentValue = context.ObjectInstance.GetType().GetProperty(PropertyName).GetValue(context.ObjectInstance, null);
if (dependentValue.ToString() != InvalidValue.ToString())
{
if (!_innerAttribute.IsValid(value))
{
return new ValidationResult(FormatErrorMessage(context.DisplayName), new[] { context.MemberName });
}
}
return ValidationResult.Success;
}
public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
{
var rule = new ModelClientValidationRule
{
ErrorMessage = ErrorMessageString,
ValidationType = "requiredifnot",
};
rule.ValidationParameters["dependentproperty"] = (context as ViewContext).ViewData.TemplateInfo.GetFullHtmlFieldId(PropertyName);
rule.ValidationParameters["invalidvalue"] = InvalidValue is bool ? InvalidValue.ToString().ToLower() : InvalidValue;
yield return rule;
}
I didn't need to make any changes to my view, but did make a change to the properties of my model:
[RequiredIfNot("Id", 0, ErrorMessage = "Please select a Source")]
public string TemplateGTSource { get; set; }
public string TemplateGTMedium
{
get
{
return "Email";
}
}
[RequiredIfNot("Id", 0, ErrorMessage = "Please enter a Campaign")]
public string TemplateGTCampaign { get; set; }
[RequiredIfNot("Id", 0, ErrorMessage = "Please enter a Term")]
public string TemplateGTTerm { get; set; }
Hope this helps!
