One should also consider another intuitive way to do this using filter()
from dplyr
. Here are some examples:
set.seed(123)
df <- data.frame(name = sample(letters, 100, TRUE),
date = sample(1:500, 100, TRUE))
library(dplyr)
filter(df, date < 50) # date less than 50
filter(df, date %in% 50:100) # date between 50 and 100
filter(df, date %in% 1:50 & name == "r") # date between 1 and 50 AND name is "r"
filter(df, date %in% 1:50 | name == "r") # date between 1 and 50 OR name is "r"
# You can also use the pipe (%>%) operator
df %>% filter(date %in% 1:50 | name == "r")
Cracked it. Basically, what's happening is that when you set the z-index to the negative, it actually ignores the parent element, whether it is positioned or not, and sits behind the next positioned element, which in your case was your main container. Therefore, you have to put your parent element in another, positioned div, and your child div will sit behind that.
Working that out was a life saver for me, as my parent element specifically couldn't be positioned, in order for my code to work.
I found all this incredibly useful to achieve the effect that's instructed on here: Using only CSS, show div on hover over <a>
Using EntityFramework.Plus could be an option:
dbContext.Employ.Where(e => e.Id == 1).Delete();
More examples are available here
Instead of trying to stop the onCreate()
from being fired altogether, maybe try checking the Bundle
savedInstanceState
being passed into the event to see if it is null or not.
For instance, if I have some logic that should be run when the Activity
is truly created, not on every orientation change, I only run that logic in the onCreate()
only if the savedInstanceState
is null.
Otherwise, I still want the layout to redraw properly for the orientation.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game_list);
if(savedInstanceState == null){
setupCloudMessaging();
}
}
not sure if this is the ultimate answer, but it works for me.
A simple graphic makes this clearer:
git diff
Shows the changes between the working directory and the index. This shows what has been changed, but is not staged for a commit.
git diff --cached
Shows the changes between the index and the HEAD (which is the last commit on this branch). This shows what has been added to the index and staged for a commit.
git diff HEAD
Shows all the changes between the working directory and HEAD (which includes changes in the index). This shows all the changes since the last commit, whether or not they have been staged for commit or not.
Also:
There is a bit more detail on 365Git.
AFAIK, there is no way to do this reliably, unless you switch to an array. Which honestly, doesn't seem strange - it's seems pretty straight forward to me that arrays are countable, and objects aren't.
Probably the closest you'll get is something like this
// Monkey patching on purpose to make a point
Object.prototype.length = function()
{
var i = 0;
for ( var p in this ) i++;
return i;
}
alert( {foo:"bar", bar: "baz"}.length() ); // alerts 3
But this creates problems, or at least questions. All user-created properties are counted, including the _length function itself! And while in this simple example you could avoid it by just using a normal function, that doesn't mean you can stop other scripts from doing this. so what do you do? Ignore function properties?
Object.prototype.length = function()
{
var i = 0;
for ( var p in this )
{
if ( 'function' == typeof this[p] ) continue;
i++;
}
return i;
}
alert( {foo:"bar", bar: "baz"}.length() ); // alerts 2
In the end, I think you should probably ditch the idea of making your objects countable and figure out another way to do whatever it is you're doing.
You can also start a server without python using php interpreter.
E.g:
cd /your/path/to/website/root
php -S localhost:8000
This can be useful if you want an alternative to npm, as php utility comes preinstalled on some OS' (including Mac).
If you use the WebStorm Javascript IDE, you can just open your project from WebStorm in your browser. WebStorm will automatically start a server and you won't get any of these errors anymore, because you are now accessing the files with the allowed/supported protocols (HTTP).
You will find multiple different methods that people use and they each have there own place.
<?php if($first_condition): ?>
/*$first_condition is true*/
<?php elseif ($second_condition): ?>
/*$first_condition is false and $second_condition is true*/
<?php else: ?>
/*$first_condition and $second_condition are false*/
<?php endif; ?>
If in your php.ini attribute short_open_tag = true
(this is normally found on line 141
of the default php.ini file) you can replace your php open tag from <?php
to <?
. This is not advised as most live server environments have this turned off (including many CMS's like Drupal, WordPress and Joomla). I have already tested short hand open tags in Drupal and confirmed that it will break your site, so stick with <?php
. short_open_tag
is not on by default in all server configurations and must not be assumed as such when developing for unknown server configurations. Many hosting companies have short_open_tag
turned off.
A quick search of short_open_tag
in stackExchange shows 830 results. https://stackoverflow.com/search?q=short_open_tag
That's a lot of people having problems with something they should just not play with.
with some server environments and applications, short hand php open tags will still crash your code even with short_open_tag
set to true
.
short_open_tag
will be removed in PHP6 so don't use short hand tags.
all future PHP versions will be dropping short_open_tag
"It's been recommended for several years that you not use the short tag "short cut" and instead to use the full tag combination. With the wide spread use of XML and use of these tags by other languages, the server can become easily confused and end up parsing the wrong code in the wrong context. But because this short cut has been a feature for such a long time, it's currently still supported for backwards compatibility, but we recommend you don't use them." – Jelmer Sep 25 '12 at 9:00 php: "short_open_tag = On" not working
and
Normally you write PHP like so: . However if allow_short_tags directive is enabled you're able to use: . Also sort tags provides extra syntax: which is equal to .
Short tags might seem cool but they're not. They causes only more problems. Oh... and IIRC they'll be removed from PHP6. Crozin answered Aug 24 '10 at 22:12 php short_open_tag problem
and
To answer the why part, I'd quote Zend PHP 5 certification guide: "Short tags were, for a time, the standard in the PHP world; however, they do have the major drawback of conflicting with XML headers and, therefore, have somewhat fallen by the wayside." – Fluffy Apr 13 '11 at 14:40 Are PHP short tags acceptable to use?
You may also see people use the following example:
<?php if($first_condition){ ?>
/*$first_condition is true*/
<?php }else if ($second_condition){ ?>
/*$first_condition is false and $second_condition is true*/
<?php }else{ ?>
/*$first_condition and $second_condition are false*/
<?php } ?>
This will work but it is highly frowned upon as it's not considered as legible and is not what you would use this format for. If you had a PHP file where you had a block of PHP code that didn't have embedded tags inside, then you would use the bracket format.
The following example shows when to use the bracket method
<?php
if($first_condition){
/*$first_condition is true*/
}else if ($second_condition){
/*$first_condition is false and $second_condition is true*/
}else{
/*$first_condition and $second_condition are false*/
}
?>
If you're doing this code for yourself you can do what you like, but if your working with a team at a job it is advised to use the correct format for the correct circumstance. If you use brackets in embedded html/php scripts that is a good way to get fired, as no one will want to clean up your code after you. IT bosses will care about code legibility and college professors grade on legibility.
UPDATE
based on comments from duskwuff its still unclear if shorthand is discouraged (by the php standards) or not. I'll update this answer as I get more information. But based on many documents found on the web about shorthand being bad for portability. I would still personally not use it as it gives no advantage and you must rely on a setting being on that is not on for every web host.

No, it is not RESTful. The only reason why you should be putting a verb (force_delete
) into the URI is if you would need to overload GET/POST methods in an environment where PUT/DELETE methods are not available. Judging from your use of the DELETE method, this is not the case.
HTTP error code 409/Conflict
should be used for situations where there is a conflict which prevents the RESTful service to perform the operation, but there is still a chance that the user might be able to resolve the conflict himself. A pre-deletion confirmation (where there are no real conflicts which would prevent deletion) is not a conflict per se, as nothing prevents the API from performing the requested operation.
As Alex said (I don't know who downvoted him, he is correct), this should be handled in the UI, because a RESTful service as such just processes requests and should be therefore stateless (i.e. it must not rely on confirmations by holding any server-side information about of a request).
Two examples how to do this in UI would be to:
(*) Please note that HTML versions prior to 5 do not support PUT and DELETE HTTP methods natively, however most modern browsers can do these two methods via AJAX calls. See this thread for details about cross-browser support.
Update (based on additional investigation and discussions):
The scenario where the service would require the force_delete=true
flag to be present violates the uniform interface as defined in Roy Fielding's dissertation. Also, as per HTTP RFC, the DELETE method may be overridden on the origin server (client), implying that this is not done on the target server (service).
So once the service receives a DELETE request, it should process it without needing any additional confirmation (regardless if the service actually performs the operation).
dir /b %temp% >temp.list
for /f "delims=" %%a in (temp.list) do call rundll32.exe advpack.dll,DelNodeRunDLL32 "%temp%\%%a"
If you were to hardcode it you would use modulus to extract the time as others suggested.
If you are returning the seconds from MySQL database, assuming you don't need the data in seconds format in your app, there is a much cleaner way to do it, you can use MySQL's SEC_TO_TIME and it will return time in hh:mm:ss format.
Eg.
SELECT SEC_TO_TIME(my_seconds_field) AS my_timestring;
an existing folder will FAIL with FileExists
Function FileExists(strFileName)
' Check if a file exists - returns True or False
use instead or in addition:
Function FolderExists(strFolderPath)
' Check if a path exists
This is impossible to answer and has been brought up many many times before. Do a search, read those threads, then pick the framework you and your team have experience with.
Using Java createBitmap()
method you can pass the degrees.
Bitmap bInput /*your input bitmap*/, bOutput;
float degrees = 45; //rotation degree
Matrix matrix = new Matrix();
matrix.setRotate(degrees);
bOutput = Bitmap.createBitmap(bInput, 0, 0, bInput.getWidth(), bInput.getHeight(), matrix, true);
There are some libraries around there:
Commons-BeanUtils: ConvertUtils -> Utility methods for converting String scalar values to objects of the specified Class, String arrays to arrays of the specified Class.
Commons-Lang: ArrayUtils -> Operations on arrays, primitive arrays (like int[]) and primitive wrapper arrays (like Integer[]).
Spring framework: Spring has an excellent support for PropertyEditors, that can also be used to transform Objects to/from Strings.
Dozer: Dozer is a powerful, yet simple Java Bean to Java Bean mapper that recursively copies data from one object to another. Typically, these Java Beans will be of different complex types.
ModelMapper: ModelMapper is an intelligent object mapping framework that automatically maps objects to each other. It uses a convention based approach to map objects while providing a simple refactoring safe API for handling specific use cases.
MapStruct: MapStruct is a compile-time code generator for bean mappings, resulting in fast (no usage of reflection or similar), dependency-less and type-safe mapping code at runtime.
Orika: Orika uses byte code generation to create fast mappers with minimal overhead.
Selma: Compile-time code-generator for mappings
JMapper: Bean mapper generation using Annotation, XML or API (seems dead, last updated 2 years ago)
Smooks: The Smooks JavaBean Cartridge allows you to create and populate Java objects from your message data (i.e. bind data to) (suggested by superfilin in comments). (No longer under active development)
Commons-Convert: Commons-Convert aims to provide a single library dedicated to the task of converting an object of one type to another. The first stage will focus on Object to String and String to Object conversions. (seems dead, last update 2010)
Transmorph: Transmorph is a free java library used to convert a Java object of one type into an object of another type (with another signature, possibly parameterized). (seems dead, last update 2013)
EZMorph: EZMorph is simple java library for transforming an Object to another Object. It supports transformations for primitives and Objects, for multidimensional arrays and transformations with DynaBeans (seems dead, last updated 2008)
Morph: Morph is a Java framework that eases the internal interoperability of an application. As information flows through an application, it undergoes multiple transformations. Morph provides a standard way to implement these transformations. (seems dead, last update 2008)
Lorentz: Lorentz is a generic object-to-object conversion framework. It provides a simple API to convert a Java objects of one type into an object of another type. (seems dead)
OTOM: With OTOM, you can copy any data from any object to any other object. The possibilities are endless. Welcome to "Autumn". (seems dead)
When You want to open new tab/window (depends on Your browser configuration defaults):
output = 'Hello, World!';
window.open().document.write(output);
When output is an Object
and You want get JSON, for example (also can generate any type of document, even image encoded in Base64)
output = ({a:1,b:'2'});
window.open('data:application/json;' + (window.btoa?'base64,'+btoa(JSON.stringify(output)):JSON.stringify(output)));
Update
Google Chrome (60.0.3112.90) block this code:
Not allowed to navigate top frame to data URL: data:application/json;base64,eyJhIjoxLCJiIjoiMiJ9
When You want to append some data to existing page

window.open('about:blank').document.body.innerText += output;
If your UML modeling tool has support for specifying an Enumeration, you should use that. It will likely be easier to do and it will give your model stronger semantics. Visually the result will be very similar to a Class with an <<enumeration>>
Stereotype, but in the UML metamodel, an Enumeration is actually a separate (meta)type.

If you're using ArgoEclipse or ArgoUML, there's a pulldown menu on the toolbar which selects among Datatype, Enumeration, Signal, etc that will allow you to create your own Enumerations. The compartment that normally contains Attributes can then be populated with EnumerationLiterals for the values of your enumeration.
Here's a picture of a slightly different example in ArgoUML:
In C# These ways you can Solve the problem, In UIkit these methods are available.

How about this? Just give it a thought-
import java.util.ArrayList;
class Solution
{
public static void main (String[] args){
ArrayList<String> List_Of_Array = new ArrayList<String>();
List_Of_Array.add("A");
List_Of_Array.add("B");
List_Of_Array.add("C");
List_Of_Array.add("D");
List_Of_Array.add("E");
List_Of_Array.add("F");
List_Of_Array.add("G");
List_Of_Array.add("H");
int i[] = {1,3,5};
for (int j = 0; j < i.length; j++) {
List_Of_Array.remove(i[j]-j);
}
System.out.println(List_Of_Array);
}
}
And the output was-
[A, C, E, G, H]
Assuming that you're constrained to using Date
, you can do the following:
Date diff = new Date(d2.getTime() - d1.getTime());
Here you're computing the differences in milliseconds since the "epoch", and creating a new Date object at an offset from the epoch. Like others have said: the answers in the duplicate question are probably better alternatives (if you aren't tied down to Date
).
int days = DateTime.DaysInMonth(int year,int month);
or
int days=System.Globalization.CultureInfo.CurrentCulture.Calendar.GetDaysInMonth(int year,int month);
you have to pass year and month as int
then days in month will be return on currespoting year and month
It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment
to your bean.
@Autowired
private Environment environment;

this.environment.getActiveProfiles();
How do you plan to save last saved position with RecyclerView.State
?
You can always rely on ol' good save state. Extend RecyclerView
and override onSaveInstanceState() and onRestoreInstanceState()
:
@Override
protected Parcelable onSaveInstanceState() {
Parcelable superState = super.onSaveInstanceState();
LayoutManager layoutManager = getLayoutManager();
if(layoutManager != null && layoutManager instanceof LinearLayoutManager){
mScrollPosition = ((LinearLayoutManager) layoutManager).findFirstVisibleItemPosition();
}
SavedState newState = new SavedState(superState);
newState.mScrollPosition = mScrollPosition;
return newState;
}
@Override
protected void onRestoreInstanceState(Parcelable state) {
super.onRestoreInstanceState(state);
if(state != null && state instanceof SavedState){
mScrollPosition = ((SavedState) state).mScrollPosition;
LayoutManager layoutManager = getLayoutManager();
if(layoutManager != null){
int count = layoutManager.getItemCount();
if(mScrollPosition != RecyclerView.NO_POSITION && mScrollPosition < count){
layoutManager.scrollToPosition(mScrollPosition);
}
}
}
}
static class SavedState extends android.view.View.BaseSavedState {
public int mScrollPosition;
SavedState(Parcel in) {
super(in);
mScrollPosition = in.readInt();
}
SavedState(Parcelable superState) {
super(superState);
}
@Override
public void writeToParcel(Parcel dest, int flags) {
super.writeToParcel(dest, flags);
dest.writeInt(mScrollPosition);
}
public static final Parcelable.Creator<SavedState> CREATOR
= new Parcelable.Creator<SavedState>() {
@Override
public SavedState createFromParcel(Parcel in) {
return new SavedState(in);
}
@Override
public SavedState[] newArray(int size) {
return new SavedState[size];
}
};
}
Whatever you do to secure your secret keys is not going to be a real solution. If developer can decompile the application there is no way to secure the key, hiding the key is just security by obscurity and so is code obfuscation. Problem with securing a secret key is that in order to secure it you have to use another key and that key needs to also be secured. Think of a key hidden in a box that is locked with a key. You place a box inside a room and lock the room. You are left with another key to secure. And that key is still going to be hardcoded inside your application.
So unless the user enters a PIN or a phrase there is no way to hide the key. But to do that you would have to have a scheme for managing PINs happening out of band, which means through a different channel. Certainly not practical for securing keys for services like Google APIs.

I know this is an old thread, but I just spent 3 hours trying to figure out what my issue was. I ordinarily know what this error means, but you can run into this in a more subtle way as well. My issue was my client class (the one calling a static method from an instance class) had a property of a different type but named the same as the static method. The error reported by the compiler was the same as reported here, but the issue was basically name collision.
For anyone else getting this error and none of the above helps, try fully qualifying your instance class with the namespace name. ..() so the compiler can see the exact name you mean.

When you want to convert your code to result( executable, library or whatever ), there is 2 steps:
1) compile
2) link
In first step compiler should now about some things like sizeof objects that used by you, prototype of functions and maybe inheritance. on the other hand linker want to find implementation of functions and global variables in your code.
Now when you use ClassTwo
in File1.cpp
compiler know nothing about it and don't know how much memory should allocate for it or for example witch members it have or is it a class and enum or even a typedef of int, so compilation will be failed by the compiler. adding File2.cpp
solve the problem of linker that look for implementation but the compiler is still unhappy, because it know nothing about your type.
So remember, in compile phase you always work with just one file( and of course files that included by that one file ) and in link phase you need multiple files that contain implementations. and since C/C++ are statically typed and they allow their identifier to work for many purposes( definition, typedef, enum class, ... ) so you should always identify you identifier to the compiler and then use it and as a rule compiler should always know size of your variable!!
The ENOSPC
("No space left on device") error will be triggered in any situation in which the data or the metadata associated with an I/O operation can't be written down anywhere because of lack of space. This doesn't always mean disk space – it could mean physical disk space, logical space (e.g. maximum file length), space in a certain data structure or address space. For example you can get it if there isn't space in the directory table (vfat) or there aren't any inodes left. It roughly means “I can't find where to write this down”.
Particularly in Python, this can happen on any write I/O operation. It can happen during f.write
, but it can also happen on open
, on f.flush
and even on f.close
. Where it happened provides a vital clue for the reason that it did – if it happened on open
there wasn't enough space to write the metadata for the entry, if it happened during f.write
, f.flush
or f.close
there wasn't enough disk space left or you've exceeded the maximum file size.
If the filesystem in the given directory is vfat
you'd hit the maximum file limit at about the same time that you did. The limit is supposed to be 2^16 directory entries, but if I recall correctly some other factors can affect it (e.g. some files require more than one entry).
It would be best to avoid creating so many files in a directory. Few filesystems handle so many directory entries with ease. Unless you're certain that your filesystem deals well with many files in a directory, you can consider another strategy (e.g. create more directories).
P.S. Also do not trust the remaining disk space – some file systems reserve some space for root and others miscalculate the free space and give you a number that just isn't true.
For Windows 8 and Windows Server 2012 use dism /online /enable-feature /featurename:IIS-ASPNET45

Have you tried using jQuery's ajax request? As of version 1.3 jQuery supports certain types of cross domain ajax requests.
Quoting from the reference above:
Note: All remote (not on the same domain) requests should be specified as GET when 'script' or 'jsonp' is the dataType (because it loads script using a DOM script tag). Ajax options that require an XMLHttpRequest object are not available for these requests. The complete and success functions are called on completion, but do not receive an XHR object; the beforeSend and dataFilter functions are not called.
As of jQuery 1.2, you can load JSON data located on another domain if you specify a JSONP callback, which can be done like so: "myurl?callback=?". jQuery automatically replaces the ? with the correct method name to call, calling your specified callback. Or, if you set the dataType to "jsonp" a callback will be automatically added to your Ajax request.
I had a similar issue where I had another class something like this:
public class Something {
MyActivity myActivity;
public Something(MyActivity myActivity) {
this.myActivity=myActivity;
}
public void someMethod() {
.
.
AlertDialog.Builder builder = new AlertDialog.Builder(myActivity);
.
AlertDialog alert = builder.create();
alert.show();
}
}
Worked fine most of the time, but sometimes it crashed with the same error. Then I realise that in MyActivity
I had...
public class MyActivity extends Activity {
public static Something something;
public void someMethod() {
if (something==null) {
something=new Something(this);
}
}
}
Because I was holding the object as static
, a second run of the code was still holding the original version of the object, and thus was still referring to the original Activity
, which no long existed.
Silly stupid mistake, especially as I really didn't need to be holding the object as static
in the first place...
You could try something like this:
...Binding="{Binding RelativeSource={RelativeSource FindAncestor,
AncestorType={x:Type Window}}, Path=DataContext.AllowItemCommand}" ...
I realize this is a very old thread, but it was very helpful when I had to put together some system documentation for several different servers that were hosting different versions of Sql Server. I ended up creating 4 stored procedures which I am posting here for the benefit of the community. We use Dynamics NAV so the two stored procedures with NAV in the name split the Nav company out of the table name. Enjoy...

I break the task up into smaller units. Test with different batch size intervals for your table, until you find an interval that performs optimally. Here is a sample that I have used in the past.
declare @counter int
declare @numOfRecords int
declare @batchsize int
set @numOfRecords = (SELECT COUNT(*) AS NumberOfRecords FROM <TABLE> with(nolock))
set @counter = 0
set @batchsize = 2500
set rowcount @batchsize
while @counter < (@numOfRecords/@batchsize) +1
begin
set @counter = @counter + 1
Update table set int_field = -1 where int_field <> -1;
end
set rowcount 0

Yes, you are synchronizing correctly. I will explain this in more detail. You must synchronize two or more method calls on the synchronizedMap object only in a case you have to rely on results of previous method call(s) in the subsequent method call in the sequence of method calls on the synchronizedMap object. Let’s take a look at this code:
synchronized (synchronizedMap) {
if (synchronizedMap.containsKey(key)) {
synchronizedMap.get(key).add(value);
}
else {
List<String> valuesList = new ArrayList<String>();
valuesList.add(value);
synchronizedMap.put(key, valuesList);
}
}
In this code
synchronizedMap.get(key).add(value);
and
synchronizedMap.put(key, valuesList);
method calls are relied on the result of the previous
synchronizedMap.containsKey(key)
method call.
If the sequence of method calls were not synchronized the result might be wrong.
For example thread 1
is executing the method addToMap()
and thread 2
is executing the method doWork()
The sequence of method calls on the synchronizedMap
object might be as follows:
Thread 1
has executed the method
synchronizedMap.containsKey(key)
and the result is "true
".
After that operating system has switched execution control to thread 2
and it has executed
synchronizedMap.remove(key)
After that execution control has been switched back to the thread 1
and it has executed for example
synchronizedMap.get(key).add(value);
believing the synchronizedMap
object contains the key
and NullPointerException
will be thrown because synchronizedMap.get(key)
will return null
.
If the sequence of method calls on the synchronizedMap
object is not dependent on the results of each other then you don't need to synchronize the sequence.
For example you don't need to synchronize this sequence:
synchronizedMap.put(key1, valuesList1);
synchronizedMap.put(key2, valuesList2);
Here
synchronizedMap.put(key2, valuesList2);
method call does not rely on the results of the previous
synchronizedMap.put(key1, valuesList1);
method call (it does not care if some thread has interfered in between the two method calls and for example has removed the key1
).

your result.

You appear to have a heredoc
containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc
:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF
or if BUILDING
is $2
in your script:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF
If your file.sql
had an exit
at the end then it would be even simpler as you wouldn't need the heredoc
:
sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2
In your SQL you can then refer to the position parameters using substitution variables:
...
}',SEM_Models('&1'),NULL,
...
The &1
will be replaced with the first value passed to the SQL script, BUILDING
; because that is a string it still needs to be enclosed in quotes. You might want to set verify off
to stop if showing you the substitutions in the output.
You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1
, the second is &2
, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF
or:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF
If total_count
is being passed to your shell script then just use its positional parameter, $4
or whatever. And your SQL would then be:
SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
?s rdf:type :ProcessSpec .
?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));
If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:
define MY_ALIAS = &1
define MY_MODEL = &2
SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
?s rdf:type :ProcessSpec .
?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));
From your separate question, maybe you just wanted:
SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
?s rdf:type :ProcessSpec .
?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));
... so the alias will be the same value you're querying on (the value in $2
, or BUILDING
in the original part of the answer). You can refer to a substitution variable as many times as you want.
That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:
select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT
If you set pages 0
and set heading off
, your repeated calls might appear in a neat list. You might also need to set tab off
and possibly use rpad('&1', 20)
or similar to make that column always the same width. Or get the results as CSV with:
select '&1' ||','|| COUNT(*)
Depends what you're using the results for...
I'm not sure if that is possible. The MSDN GetFiles reference says a search pattern, not a list of search patterns.
I might be inclined to fetch each list separately and "foreach" them into a final list.
For what it's worth, the Mock docs talk about datetime.date.today specifically, and it's possible to do this without having to create a dummy class:
https://docs.python.org/3/library/unittest.mock-examples.html#partial-mocking
>>> from datetime import date
>>> with patch('mymodule.date') as mock_date:
... mock_date.today.return_value = date(2010, 10, 8)
... mock_date.side_effect = lambda *args, **kw: date(*args, **kw)
...
... assert mymodule.date.today() == date(2010, 10, 8)
... assert mymodule.date(2009, 6, 8) == date(2009, 6, 8)
...
Your compiler may have a warning that it can generate if a base class function becomes hidden. If it does, enable it. That will catch const clashes and differences in parameter lists. Unfortunately this won't uncover a spelling error.
For example, this is warning C4263 in Microsoft Visual C++.
This is why I wrote Picky: http://picky.readthedocs.io/
It's a python package that tracks packages installed with either pip or conda in either virtualenvs and conda envs.
You can use this property : vertical-align:middle;
.selector-class {
float:left;
vertical-align:middle;
}
$("input[type=checkbox]").on("change", function() {
if (this.checked) {
//do your stuff
}
});
If you are using Reactive form you can set it to default like this:
In the form model, set the value to false. So if it's checked its value will be true else false
let form = this.formBuilder.group({
is_known: [false]
})
//In HTML
<mat-checkbox matInput formControlName="is_known">Known</mat-checkbox>
I'm not sure what you're doing, but this will go from JSON to CSV using JavaScript. This is using the open source JSON library, so just download JSON.js into the same folder you saved the code below into, and it will parse the static JSON value in json3

If the coding standards for the particular codebase I am writing code for specifies which operator should be used, I'll definitely use that. If not, and the code dictates which should be used (not often, can be easily worked around) then I'll use that. Otherwise, probably &&
.
Is 'and' more readable than '&&'?
Is it more readable to you. The answer is yes and no depending on many factors including the code around the operator and indeed the person reading it!
|| there is ~ difference?
Yes. See logical operators for ||
and bitwise operators for ~
.

I had this issue was trying to remove a ui element inside an event reactive:
myReactives <- eventReactive(input$execute, {
... # Some other long running function here
removeUI(selector = "#placeholder2")
})
I was getting this error, but not on the removeUI element line, it was in the next observer after for some reason. Taking the removeUI method out of the eventReactive and placing it somewhere else removed this error for me.
As I wrote in my comment, the solution to your problem is to write the following:
Set hyperLinkText = hprlink.Range
Set
is needed because TextRange
is a class, so hyperLinkText
is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.
This will work if the department, salary and employee name are in the same table.
select ed.emp_name, ed.salary, ed.dept from
(select max(salary) maxSal, dept from emp_dept group by dept) maxsaldept
inner join emp_dept ed

Is there any better solution than this?
You can use the event ProgressChanged ; the last time it is raised will indicate that the document is fully rendered:
this.webBrowser.ProgressChanged += new
WebBrowserProgressChangedEventHandler(webBrowser_ProgressChanged);
I seconded Matthieu answer
I commented #Listen 443 in httpd-ssl file and apache can be started
Because the file already has VirtualHost default:443
If you are using Sentry
check the logged in user with Sentry::getUser()->id
. The error you get is that the Auth::user()
returns NULL and it tries to get id from NULL hence the error trying to get a property from a non-object
.
This is exactly the feature I implemented in this lib XDDLib. (But, it's for android)
Lg.d("int array:", intArrayOf(1, 2, 3), "int list:", listOf(4, 5, 6))
One click on the underlined text to navigate to where the log command is
That StackTraceElement
is determined by the first element outside this library. Thus, anywhere outside this lib will be legal, including lambda expression
, static initialization block
, etc.
This issue also bother me and then i find possible cases to reproduce this issue
when i run my window in administrator then it working fine ng but when i run this in my second space like other user then i got this issue.
so if i want to run my angular application then i need to run this command
npm run ng serve which is working but when i run the command with --host npm run ng server --host IP it not working given some error
so i find some possible solution 1. go appdata and then user\admin\AppData\Roaming\npm folder then copy this path but if you using other user account user\newuser\AppData\Roaming\npm folder you can copy this npm folder from other user i.e admin user account. if you do not want to copy this folder then copy the path of ****user\admin\AppData\Roaming\npm folder**** folder and then open your environment variable setting and add this path in path variable name
enter this path in system path variable not user variable C:\Users\admin\AppData\Roaming\npm
and run the command prompt as administrator then run ng command it will work
Basically there's a program to accomplish that, called "mail". The subject of the email can be specified with a -s and a list of address with -t. You can write the text on your own with the echo command:
echo "This will go into the body of the mail." | mail -s "Hello world" [email protected]
or get it from other files too:
mail -s "Hello world" [email protected] < /home/calvin/application.log
mail doesn't support the sending of attachments, but Mutt does:
echo "Sending an attachment." | mutt -a file.zip -s "attachment" [email protected]
Note that Mutt's much more complete than mail. You can find better explanation here
PS: thanks to @slhck who pointed out that my previous answer was awful. ;)
Is Easy, Example: Valid for HTML5 automatic type="date".
<script type="text/javascript" src="//ajax.aspnetcdn.com/ajax/jquery.validate/1.14.0/jquery.validate.min.js"></script>
<script type="text/javascript" src="//ajax.aspnetcdn.com/ajax/jquery.validate/1.14.0/additional-methods.min.js"></script>
<script type="text/javascript" src="//ajax.aspnetcdn.com/ajax/jquery.validate/1.14.0/localization/messages_es.js"></script>
$(function () {
// Overload method default "date" jquery.validate.min.js
$.validator.addMethod(
"date",
function(value, element) {
var dateReg = /^\d{2}([./-])\d{2}\1\d{4}$/;
return value.match(dateReg);
},
"Invalid date"
);
// Form Demo jquery.validate.min.js
$('#form-datos').validate({
submitHandler: function(form) {
form.submit();
}
});
});
I think cURL would be a good solution. This is not tested, but you can try something like this:
$body = '{
"kind": "blogger#post",
"blog": {
"id": "8070105920543249955"
},
"title": "A new post",
"content": "With <b>exciting</b> content..."
}';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.googleapis.com/blogger/v3/blogs/8070105920543249955/posts/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json","Authorization: OAuth 2.0 token here"));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $body);
$result = curl_exec($ch);
The document
and window
are different objects and they have some different events. Using addEventListener()
on them listens to events destined for a different object. You should use the one that actually has the event you are interested in.
For example, there is a "resize"
event on the window
object that is not on the document
object.
For example, the "DOMContentLoaded"
event is only on the document
object.
So basically, you need to know which object receives the event you are interested in and use .addEventListener()
on that particular object.
Here's an interesting chart that shows which types of objects create which types of events: https://developer.mozilla.org/en-US/docs/DOM/DOM_event_reference
If you are listening to a propagated event (such as the click event), then you can listen for that event on either the document object or the window object. The only main difference for propagated events is in timing. The event will hit the document
object before the window
object since it occurs first in the hierarchy, but that difference is usually immaterial so you can pick either. I find it generally better to pick the closest object to the source of the event that meets your needs when handling propagated events. That would suggest that you pick document
over window
when either will work. But, I'd often move even closer to the source and use document.body
or even some closer common parent in the document (if possible).
Might be irrelevant for OP's Q, but I've tried all openssl statements with all the different flags, while trying to connect with PHP \SoapClient(...)
and after 3 days I finally found a solution that worked for me.
$ cd path/to/certificate/
$ openssl pkcs12 -in personal_certificate.pfx -out public_key.pem -clcerts
First you have to enter YOUR_CERT_PASSWORD
once, then DIFFERENT_PASSWORD!
twice. The latter will possibly be available to everyone with access to code.
<?php
$wsdlUrl = "https://example.com/service.svc?singlewsdl";
$publicKey = "rel/path/to/certificate/public_key.pem";
$password = "DIFFERENT_PASSWORD!";
$params = [
'local_cert' => $publicKey,
'passphrase' => $password,
'trace' => 1,
'exceptions' => 0
];
$soapClient = new \SoapClient($wsdlUrl, $params);
var_dump($soapClient->__getFunctions());
Great answer Alex. One potential issue is the NULL dereference. Apple's reference on Creating and Returning NSError objects
...
[details setValue:@"ran out of money" forKey:NSLocalizedDescriptionKey];
if (error != NULL) {
// populate the error object with the details
*error = [NSError errorWithDomain:@"world" code:200 userInfo:details];
}
// we couldn't feed the world's children...return nil..sniffle...sniffle
return nil;
...
TL;DR
You should use FLUSH PRIVILEGES;
only if you modify the grant tables directly using statements such as INSERT
, UPDATE
, or DELETE
.
You have to wrap the word in a span to accomplish this.
declare @xx int
set @xx = 3
select @xx
select @xx * 2 -- yields another integer
select @xx/1 -- same
select @xx/1.0 --yields 6 decimal places
select @xx/1.00 -- 6
select @xx * 1.0 -- 1 decimal place - victory
select @xx * 1.00 -- 2 places - hooray
Also _ inserting an int into a temp_table with like decimal(10,3) _ works ok.
To call a specific exception such as FileNotFoundException use this format
if (-not (Test-Path $file))
{
throw [System.IO.FileNotFoundException] "$file not found."
}
To throw a general exception use the throw command followed by a string.
throw "Error trying to do a task"
When used inside a catch, you can provide additional information about what triggered the error
I've had the same problem. The solution was to remove proxy from Chrome settings. Also you could have an extension that use proxy. Try to disable it.
$date1 = date_create('2007-03-24');
$date2 = date_create('2009-06-26');
$interval = date_diff($date1, $date2);
echo "difference : " . $interval->y . " years, " . $interval->m." months, ".$interval->d." days ";
I know this is old, but I just solved it with this:
var update_size = function() {
$(oTable).css({ width: $(oTable).parent().width() });
oTable.fnAdjustColumnSizing();
}
$(window).resize(function() {
clearTimeout(window.refresh_size);
window.refresh_size = setTimeout(function() { update_size(); }, 250);
});
Note: This answer applies to DataTables 1.9
The question is tagged SQL Server 2000 but for the benefit of people developing on the latest version I'll address that first.
SQL Server 2014
In addition to the methods of adding constraint based indexes discussed below SQL Server 2014 also allows non unique indexes to be specified directly with inline syntax on table variable declarations.
Example syntax for that is below.
/*SQL Server 2014+ compatible inline index syntax*/
DECLARE @T TABLE (
C1 INT INDEX IX1 CLUSTERED, /*Single column indexes can be declared next to the column*/
C2 INT INDEX IX2 NONCLUSTERED,
INDEX IX3 NONCLUSTERED(C1,C2) /*Example composite index*/
);
Filtered indexes and indexes with included columns can not currently be declared with this syntax however SQL Server 2016 relaxes this a bit further. From CTP 3.1 it is now possible to declare filtered indexes for table variables. By RTM it may be the case that included columns are also allowed but the current position is that they "will likely not make it into SQL16 due to resource constraints"
/*SQL Server 2016 allows filtered indexes*/
DECLARE @T TABLE
(
c1 INT NULL INDEX ix UNIQUE WHERE c1 IS NOT NULL /*Unique ignoring nulls*/
)
SQL Server 2000 - 2012
Can I create a index on Name?
Short answer: Yes.
DECLARE @TEMPTABLE TABLE (
[ID] [INT] NOT NULL PRIMARY KEY,
[Name] [NVARCHAR] (255) COLLATE DATABASE_DEFAULT NULL,
UNIQUE NONCLUSTERED ([Name], [ID])
)
A more detailed answer is below.
Traditional tables in SQL Server can either have a clustered index or are structured as heaps.
Clustered indexes can either be declared as unique to disallow duplicate key values or default to non unique. If not unique then SQL Server silently adds a uniqueifier to any duplicate keys to make them unique.
Non clustered indexes can also be explicitly declared as unique. Otherwise for the non unique case SQL Server adds the row locator (clustered index key or RID for a heap) to all index keys (not just duplicates) this again ensures they are unique.
In SQL Server 2000 - 2012 indexes on table variables can only be created implicitly by creating a UNIQUE
or PRIMARY KEY
constraint. The difference between these constraint types are that the primary key must be on non nullable column(s). The columns participating in a unique constraint may be nullable. (though SQL Server's implementation of unique constraints in the presence of NULL
s is not per that specified in the SQL Standard). Also a table can only have one primary key but multiple unique constraints.
Both of these logical constraints are physically implemented with a unique index. If not explicitly specified otherwise the PRIMARY KEY
will become the clustered index and unique constraints non clustered but this behavior can be overridden by specifying CLUSTERED
or NONCLUSTERED
explicitly with the constraint declaration (Example syntax)
DECLARE @T TABLE
(
A INT NULL UNIQUE CLUSTERED,
B INT NOT NULL PRIMARY KEY NONCLUSTERED
)
As a result of the above the following indexes can be implicitly created on table variables in SQL Server 2000 - 2012.
+-------------------------------------+-------------------------------------+
| Index Type | Can be created on a table variable? |
+-------------------------------------+-------------------------------------+
| Unique Clustered Index | Yes |
| Nonunique Clustered Index | |
| Unique NCI on a heap | Yes |
| Non Unique NCI on a heap | |
| Unique NCI on a clustered index | Yes |
| Non Unique NCI on a clustered index | Yes |
+-------------------------------------+-------------------------------------+
The last one requires a bit of explanation. In the table variable definition at the beginning of this answer the non unique non clustered index on Name
is simulated by a unique index on Name,Id
(recall that SQL Server would silently add the clustered index key to the non unique NCI key anyway).
A non unique clustered index can also be achieved by manually adding an IDENTITY
column to act as a uniqueifier.
DECLARE @T TABLE
(
A INT NULL,
B INT NULL,
C INT NULL,
Uniqueifier INT NOT NULL IDENTITY(1,1),
UNIQUE CLUSTERED (A,Uniqueifier)
)
But this is not an accurate simulation of how a non unique clustered index would normally actually be implemented in SQL Server as this adds the "Uniqueifier" to all rows. Not just those that require it.
I use the code I found @.w3resources
The code takes care of
month being less than 12,
days being less than 32
even works with leap years. While Using in my project for leap year I modify the code like
if ((lyear==false) && (dd>=29))
{
alert('Invalid date format!');
return false;
}
if ((lyear==false) && (dd>=29))
{
alert('not a Leap year February cannot have more than 28days');
return false;
}
Rather than throwing the generic "Invalid date format" error which does not make much sense to the user. I modify the rest of the code to provide valid error message like month cannot be more than 12, days cannot be more than 31 etc.,
The problem with using Regular expression is it is difficult to identify exactly what went wrong. It either gives a True or a false-Without any reason why it failed. We have to write multiple regular expressions to sort this problem.
PHP 7 improved query.........
$sql = mysqli_query($conn, "SELECT * from users WHERE user_uid = '$uid'");
if (mysqli_num_rows($sql) > 0) {
echo 'Username taken.';
}
Thanks for all the replies. I went through all of them and came up with a function that gives the first an last index of each occurrence of the 'needle' substring . I am posting it here in case it will help someone.
Please note, it is not the same as the original request for only the beginning of each occurrence. It suits my usecase better because you don't need to keep the needle length.
function findRegexIndices(text, needle, caseSensitive){
var needleLen = needle.length,
reg = new RegExp(needle, caseSensitive ? 'gi' : 'g'),
indices = [],
result;
while ( (result = reg.exec(text)) ) {
indices.push([result.index, result.index + needleLen]);
}
return indices
}
Use the built-in getattr
function to get an attribute on an object by name. Modify the name as needed.
obj.spam = 'eggs'
name = 'spam'
getattr(obj, name) # returns 'eggs'
Try using string.Contains () combined with EndsWith.
var results = from c in db.Customers
where c.FullName.Contains (FirstName) && c.FullName.EndsWith (LastName)
select c;
My 2 cents:
If you are concatenating a significant amount of strings, you should be using the StringBuilder instead. IMO it's cleaner, and significantly faster.
If you want to use numbers in a sequence, define a new sequence with something like
CREATE SEQUENCE public.your_sequence
INCREMENT 1
START 1
MINVALUE 1
;
and then alter the table to use the sequence for the id:
ALTER TABLE ONLY table ALTER COLUMN id SET DEFAULT nextval('your_sequence'::regclass);
As a workaround, you could use the timestamp (old and new) for checking though, that one is not updated when there are no changes to the row. (Possibly that is the source for confusion? Because that one is also called 'on update' but is not executed when no change occurs) Changes within one second will then not execute that part of the trigger, but in some cases that could be fine (like when you have an application that rejects fast changes anyway.)
For example, rather than
IF NEW.a <> OLD.a or NEW.b <> OLD.b /* etc, all the way to NEW.z <> OLD.z */
THEN
INSERT INTO bar (a, b) VALUES(NEW.a, NEW.b) ;
END IF
you could use
IF NEW.ts <> OLD.ts
THEN
INSERT INTO bar (a, b) VALUES(NEW.a, NEW.b) ;
END IF
Then you don't have to change your trigger every time you update the scheme (the issue you mentioned in the question.)
EDIT: Added full example
create table foo (a INT, b INT, ts TIMESTAMP);
create table bar (a INT, b INT);
INSERT INTO foo (a,b) VALUES(1,1);
INSERT INTO foo (a,b) VALUES(2,2);
INSERT INTO foo (a,b) VALUES(3,3);

It is working because of mysql's behavior on handling timestamps. The time stamp is only updated if a change occured in the updates.

So let's say after getMasterData servlet will response.sendRedirect to to test.jsp.
In test.jsp
Create a javascript
<script type="text/javascript">
function alertName(){
alert("Form has been submitted");
}
</script>
and than at the bottom
<script type="text/javascript"> window.onload = alertName; </script>
Note:im not sure how to type the code in stackoverflow!. Edit: I just learned how to
Edit 2: TO the question:This works perfectly. Another question. How would I get rid of the initial alert when I first start up the JSP? "Form has been submitted" is present the second I execute. It shows up after the load is done to which is perfect.
To do that i would highly recommendation to use session!
So what you want to do is in your servlet:
session.setAttribute("getAlert", "Yes");//Just initialize a random variable.
response.sendRedirect(test.jsp);
than in the test.jsp
<%
session.setMaxInactiveInterval(2);
%>
<script type="text/javascript">
var Msg ='<%=session.getAttribute("getAlert")%>';
if (Msg != "null") {
function alertName(){
alert("Form has been submitted");
}
}
</script>
and than at the bottom
<script type="text/javascript"> window.onload = alertName; </script>
So everytime you submit that form a session will be pass on! If session is not null the function will run!
Create key value pairs on the phpsh commandline like this:
php> $keyvalues = array();
php> $keyvalues['foo'] = "bar";
php> $keyvalues['pyramid'] = "power";
php> print_r($keyvalues);
Array
(
[foo] => bar
[pyramid] => power
)
Get the count of key value pairs:
php> echo count($offerarray);
2
Get the keys as an array:
php> echo implode(array_keys($offerarray));
foopyramid
In my case I had to wrap the bootstrapping of my second app in angular.element(document).ready
for it to work:
angular.element(document).ready(function() {
angular.bootstrap(document.getElementById("app2"), ["app2"]);
});
As you can see in the documentation of JSHint you can change options per function or per file. In your case just place a comment in your file or even more local just in the function that uses eval
:
/*jshint evil:true */
function helloEval(str) {
/*jshint evil:true */
eval(str);
}
By using AppCompat textAllCaps
in Android Apps supporting older API's (less than 14)
There is one UI widgets that ships with AppCompat named CompatTextView is a Custom TextView extension that adds support for textAllCaps
For newer android API > 14 you can use :
android:textAllCaps="true"
A simple example:
<android.support.v7.internal.widget.CompatTextView
android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:textAllCaps="true"/>
Source:developer.android
Update:
As it so happens CompatTextView was replaced by AppCompatTextView in latest appcompat-v7 library ~ Eugen Pechanec
This is an old question, but I feel the urge to extend the answers with a solution I didn't see here.
You can fake the Microsoft assemly (System.Net.Http) and then use ShinsContext during the test.
Depends on your implementation and test, I would suggest to implement all the desired acting where you call a method on the HttpClient and want to fake the returned value. Using ShimHttpClient.AllInstances will fake your implementation in all the instances created during your test. For example, if you want to fake the GetAsync() method, do the following:
[TestMethod]
public void FakeHttpClient()
{
using (ShimsContext.Create())
{
System.Net.Http.Fakes.ShimHttpClient.AllInstances.GetAsyncString = (c, requestUri) =>
{
//Return a service unavailable response
var httpResponseMessage = new HttpResponseMessage(HttpStatusCode.ServiceUnavailable);
var task = Task.FromResult(httpResponseMessage);
return task;
};
//your implementation will use the fake method(s) automatically
var client = new Connection(_httpClient);
client.doSomething();
}
}
If some of your services are balking into ulimits, it's sometimes easier to put appropriate commands into service's init-script. For example, when Apache is reporting
[alert] (11)Resource temporarily unavailable: apr_thread_create: unable to create worker thread
Try to put ulimit -s unlimited
into /etc/init.d/httpd
. This does not require a server reboot.
According to the release-notes, Java 11 removed the Java EE modules:
java.xml.bind (JAXB) - REMOVED
See JEP 320 for more info.
You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.0</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-core</artifactId>
<version>2.3.0</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.3.0</version>
</dependency>
Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:
<dependency>
<groupId>jakarta.xml.bind</groupId>
<artifactId>jakarta.xml.bind-api</artifactId>
<version>2.3.3</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.3.3</version>
<scope>runtime</scope>
</dependency>
Use latest release of Eclipse Implementation of JAXB 3.0.0:
<dependency>
<groupId>jakarta.xml.bind</groupId>
<artifactId>jakarta.xml.bind-api</artifactId>
<version>3.0.0</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>3.0.0</version>
<scope>runtime</scope>
</dependency>
Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*
, so update import statements:
javax.xml.bind -> jakarta.xml.bind
When used in conjunction with the optional (nonstandard) attribute ZEROFILL, the default padding of spaces is replaced with zeros. For example, for a column declared as INT(4) ZEROFILL, a value of 5 is retrieved as 0005.
Here is an example of showing the line number of where exception takes place.
import sys
try:
print(5/0)
except Exception as e:
print('Error on line {}'.format(sys.exc_info()[-1].tb_lineno), type(e).__name__, e)
print('And the rest of program continues')
As stated in other answers, label is an inline element. However, you can apply display: inline-block
to the label and then center with text-align
.
#name_label {
display: inline-block;
width: 90%;
text-align: right;
}
Why display: inline-block
and not display: inline
? For the same reason that you can't align label
, it's inline.
Why display: inline-block
and not display: block
? You could use display: block
, but it will be on another line. display: inline-block
combines the properties of inline
and block
. It's inline, but you can also give it a width, height, and align it.
Why not try:
import datetime as dt
start_date = dt.datetime(2012, 12,1)
end_date = dt.datetime(2012, 12,5)
total_days = (end_date - start_date).days + 1 #inclusive 5 days
for day_number in range(total_days):
current_date = (start_date + dt.timedelta(days = day_number)).date()
print current_date
Just to correct and slightly extend Scott Wilson answer.
You can use data.table's setnames
function on data.frames too.
Do not expect speed up of the operation but you can expect the setnames
to be more efficient for memory consumption as it updates column names by reference. This can be tracked with address
function, see below.
library(data.table)
set.seed(123)
n = 1e8
df = data.frame(bad=sample(1:3, n, TRUE), worse=rnorm(n))
address(df)
#[1] "0x208f9f00"
colnames(df) <- c("good", "better")
address(df)
#[1] "0x208fa1d8"
rm(df)
dt = data.table(bad=sample(1:3, n, TRUE), worse=rnorm(n))
address(dt)
#[1] "0x535c830"
setnames(dt, c("good", "better"))
address(dt)
#[1] "0x535c830"
rm(dt)
So if you are hitting your memory limits you may consider to use this one instead.
case_when
is now a pretty clean implementation of the SQL-style case when:
structure(list(a = c(1, 3, 4, 6, 3, 2, 5, 1), b = c(1, 3, 4,

Edit (2020.12.28): GitHub change default master branch to main branch since October 2020. See https://github.com/github/renaming
Update March 2013
Git 1.8.2 added the possibility to track branches.
"
git submodule
" started learning a new mode to integrate with the tip of the remote branch (as opposed to integrating with the commit recorded in the superproject's gitlink).
# add submodule to track master branch
git submodule add -b master [URL to Git repo];
# update your submodule
git submodule update --remote
If you had a submodule already present you now wish would track a branch, see "how to make an existing submodule track a branch".
Also see Vogella's tutorial on submodules for general information on submodules.
Note:
git submodule add -b . [URL to Git repo];
^^^
A special value of
.
is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.
See commit b928922727d6691a3bdc28160f93f25712c565f6:
submodule add
: If --branch
is given, record it in .gitmodules
This allows you to easily record a
submodule.<name>.branch
option in.gitmodules
when you add a new submodule. With this patch,
$ git submodule add -b <branch> <repository> [<path>]
$ git config -f .gitmodules submodule.<path>.branch <branch>
reduces to
$ git submodule add -b <branch> <repository> [<path>]
This means that future calls to
$ git submodule update --remote ...
will get updates from the same branch that you used to initialize the submodule, which is usually what you want.

Original answer (February 2012):
A submodule is a single commit referenced by a parent repo.
Since it is a Git repo on its own, the "history of all commits" is accessible through a git log
within that submodule.
So for a parent to track automatically the latest commit of a given branch of a submodule, it would need to:
gitslave (that you already looked at) seems to be the best fit, including for the commit operation.
It is a little annoying to make changes to the submodule due to the requirement to check out onto the correct submodule branch, make the change, commit, and then go into the superproject and commit the commit (or at least record the new location of the submodule).
Other alternatives are detailed here.
There's two parts to this question, really.
Q: Which browsers support the "async" attribute on a script tag in markup?
A: IE10p2+, Chrome 11+, Safari 5+, Firefox 3.6+
Q: Which browsers support the new spec that defines behavior for the "async" property in JavaScript, on a dynamically created script element?
A: IE10p2+, Chrome 12+, Safari 5.1+, Firefox 4+
As for Opera, they are very close to releasing a version which will support both types of async. I've been working with them closely on this, and it should come out soon (I hope!).
More info on ordered-async (aka, "async=false") can be found here: http://wiki.whatwg.org/wiki/Dynamic_Script_Execution_Order
Also, to test if a browser supports the new dynamic async property behavior: http://test.getify.com/test-async/
The previous answers are all good, but they all show origin/master. These days, following the best practices, I rarely work directly on a master branch, let alone from origin repo.
So if you are like me who work in a branch, here are tips:
Or more simply, just use HEAD:
It should start again and delete all the instances of previous current activity.
No, it shouldn't.
It should update its data in place (e.g., requery()
the Cursor
). Then there will be no "instances of previous current activity" to worry about.
Just came accross this use case. I implemented gens's answer, adding a recursive approach for handling values that are also dicts:
def mutate_dict_in_place(f, d):
for k, v in d.iteritems():
if isinstance(v, dict):
mutate_dict_in_place(f, v)
else:
d[k] = f(v)
# Exemple handy usage
def utf8_everywhere(d):
mutate_dict_in_place((
lambda value:
value.decode('utf-8')
if isinstance(value, bytes)
else value
),
d
)
my_dict = {'a': b'byte1', 'b': {'c': b'byte2', 'd': b'byte3'}}
utf8_everywhere(my_dict)
print(my_dict)
This can be useful when dealing with json or yaml files that encode strings as bytes in Python 2
Move the jar files from your classpath to web-inf/lib, and run a new tomcat server.
I tried most of methods mentioned above but they didn't work for me, after some searches I found these points:
-n [number]
del
but if there are thousands or millions of keys it's better to use unlink
because unlink is non-blocking while del is blocking, for more information visit this page unlink vs delkeys
are like del and is blockingso I used this code to delete keys by pattern:
redis-cli -n 2 --scan --pattern '[your pattern]' | xargs redis-cli -n 2 unlink
In my case, I have to calculate the difference in minutes and julianday()
does not give an accurate value. Instead, I use strftime()
:
SELECT (strftime('%s', [UserEnd]) - strftime('%s', [UserStart])) / 60
Both dates are converted to unixtime (seconds), then subtracted to get value in seconds between the two dates. Next, divide it by 60.
Pandas Timestamp to datetime.datetime:
pd.Timestamp('2014-01-23 00:00:00', tz=None).to_pydatetime()
datetime.datetime to Timestamp
pd.Timestamp(datetime(2014, 1, 23))
I'm going to add a somewhat longer and more detailed explanation of the steps to take to solve this problem. I apologize if it's too long.
I'll start out with the base you've given and use it to define a couple of terms that I'll use for the rest of this post. This will be the base table:
select * from history;
+--------+----------+-----------+
| hostid | itemname | itemvalue |
+--------+----------+-----------+
| 1 | A | 10 |
| 1 | B | 3 |
| 2 | A | 9 |
| 2 | C | 40 |
+--------+----------+-----------+
This will be our goal, the pretty pivot table:
select * from history_itemvalue_pivot;
+--------+------+------+------+
| hostid | A | B | C |
+--------+------+------+------+
| 1 | 10 | 3 | 0 |
| 2 | 9 | 0 | 40 |
+--------+------+------+------+
Values in the history.hostid
column will become y-values in the pivot table. Values in the history.itemname
column will become x-values (for obvious reasons).
When I have to solve the problem of creating a pivot table, I tackle it using a three-step process (with an optional fourth step):
Let's apply these steps to your problem and see what we get:
Step 1: select columns of interest. In the desired result, hostid
provides the y-values and itemname
provides the x-values.
Step 2: extend the base table with extra columns. We typically need one column per x-value. Recall that our x-value column is itemname
:
create view history_extended as (
select
history.*,
case when itemname = "A" then itemvalue end as A,
case when itemname = "B" then itemvalue end as B,
case when itemname = "C" then itemvalue end as C
from history
);
select * from history_extended;
+--------+----------+-----------+------+------+------+
| hostid | itemname | itemvalue | A | B | C |
+--------+----------+-----------+------+------+------+
| 1 | A | 10 | 10 | NULL | NULL |
| 1 | B | 3 | NULL | 3 | NULL |
| 2 | A | 9 | 9 | NULL | NULL |
| 2 | C | 40 | NULL | NULL | 40 |
+--------+----------+-----------+------+------+------+
Note that we didn't change the number of rows -- we just added extra columns. Also note the pattern of NULL
s -- a row with itemname = "A"
has a non-null value for new column A
, and null values for the other new columns.
Step 3: group and aggregate the extended table. We need to group by hostid
, since it provides the y-values:
create view history_itemvalue_pivot as (
select
hostid,
sum(A) as A,
sum(B) as B,
sum(C) as C
from history_extended
group by hostid
);
select * from history_itemvalue_pivot;
+--------+------+------+------+
| hostid | A | B | C |
+--------+------+------+------+
| 1 | 10 | 3 | NULL |
| 2 | 9 | NULL | 40 |
+--------+------+------+------+
(Note that we now have one row per y-value.) Okay, we're almost there! We just need to get rid of those ugly NULL
s.
Step 4: prettify. We're just going to replace any null values with zeroes so the result set is nicer to look at:
create view history_itemvalue_pivot_pretty as (
select
hostid,
coalesce(A, 0) as A,
coalesce(B, 0) as B,
coalesce(C, 0) as C
from history_itemvalue_pivot
);
select * from history_itemvalue_pivot_pretty;
+--------+------+------+------+
| hostid | A | B | C |
+--------+------+------+------+
| 1 | 10 | 3 | 0 |
| 2 | 9 | 0 | 40 |
+--------+------+------+------+
And we're done -- we've built a nice, pretty pivot table using MySQL.
Considerations when applying this procedure:
itemvalue
in this exampleNULL
, but it could also be 0
or ""
, depending on your exact situationsum
, but count
and max
are also often used (max
is often used when building one-row "objects" that had been spread across many rows)group by
clause (and don't forget to select
them)Known limitations:
Another option for you is a linked list. You'll need to analyze how your program will use the data structure, if you don't need random access it could be faster than reallocating.
The following code emulates exactly the behavior of pointers in C:
from collections import deque # more efficient than list for appending things
pointer_storage = deque()
pointer_address = 0
class new:
def __init__(self):
global pointer_storage
global pointer_address
self.address = pointer_address
self.val = None
pointer_storage.append(self)
pointer_address += 1
def get_pointer(address):
return pointer_storage[address]
def get_address(p):
return p.address
null = new() # create a null pointer, whose address is 0
Here are examples of use:
p = new()
p.val = 'hello'
q = new()
q.val = p
r = new()
r.val = 33
p = get_pointer(3)
print(p.val, flush = True)
p.val = 43
print(get_pointer(3).val, flush = True)
But it's now time to give a more professional code, including the option of deleting pointers, that I've just found in my personal library:
# C pointer emulation:
from collections import deque # more efficient than list for appending things
from sortedcontainers import SortedList #perform add and discard in log(n) times
class new:
# C pointer emulation:
# use as : p = new()
# p.val
# p.val = something
# p.address
# get_address(p)
# del_pointer(p)
# null (a null pointer)
__pointer_storage__ = SortedList(key = lambda p: p.address)
__to_delete_pointers__ = deque()
__pointer_address__ = 0
def __init__(self):
self.val = None
if new.__to_delete_pointers__:
p = new.__to_delete_pointers__.pop()
self.address = p.address
new.__pointer_storage__.discard(p) # performed in log(n) time thanks to sortedcontainers
new.__pointer_storage__.add(self) # idem
else:
self.address = new.__pointer_address__
new.__pointer_storage__.add(self)
new.__pointer_address__ += 1
def get_pointer(address):
return new.__pointer_storage__[address]
def get_address(p):
return p.address
def del_pointer(p):
new.__to_delete_pointers__.append(p)
null = new() # create a null pointer, whose address is 0
Check if other view has the property match_parent
or fill_parent
,those properties may cover your ImageView
which has shown in your RelativeLayout
.By the way,the accepted answer does not work in my case.
string s2 = s1.Replace(",", "," + Environment.NewLine);
Also, just from a performance perspective, here's how the three current solutions I've seen stack up over 100k iterations:
ReplaceWithConstant - Ms: 328, Ticks: 810908
ReplaceWithEnvironmentNewLine - Ms: 310, Ticks: 766955
SplitJoin - Ms: 483, Ticks: 1192545
ReplaceWithConstant:
string s2 = s1.Replace(",", ",\n");
ReplaceWithEnvironmentNewLine:
string s2 = s1.Replace(",", "," + Environment.NewLine);
SplitJoin:
string s2 = String.Join("," + Environment.NewLine, s1.Split(','));
ReplaceWithEnvironmentNewLine and ReplaceWithConstant are within the margin of error of each other, so there's functionally no difference.
Using Environment.NewLine
should be preferred over "\n"
for the sake readability and consistency similar to using String.Empty
instead of ""
.
I have used _itoa(...) on RedHat 6 and GCC compiler. It works.
$first_value = reset($array); // First element's value
$first_key = key($array); // First element's key
I have my menu in the site master page. I used the Page_Load() function to make the "Admin" menu item only visible to users with an Admin role.
using System;
using System.Linq;
using Telerik.Web.UI;
using System.Web.Security;
<telerik:RadMenu ID="menu" runat="server" RenderMode="Auto" >
<Items>
<telerik:RadMenuItem Text="Admin" Visible="true" />
</Items>
</telerik:RadMenu>
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
RadMenuItem item = this.menu.FindItemByText("Admin");
if (null != item)
{
if (Roles.IsUserInRole("Admin"))
{
item.Visible = true;
}
else
{
item.Visible = false;
}
}
}
}
After many answers that did not work, I finally found a solution when Anonymous access is Disabled on the IIS server. Our server is using Windows authentication, not Kerberos. This is thanks to this blog posting.
No changes were made to web.config.
On the server side, the .SVC file in the ISAPI folder uses MultipleBaseAddressBasicHttpBindingServiceHostFactory
The class attributes of the service are:
[BasicHttpBindingServiceMetadataExchangeEndpointAttribute]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
public class InvoiceServices : IInvoiceServices
{
...
}
On the client side, the key that made it work was the http binding security attributes:
EndpointAddress endpoint =
new EndpointAddress(new Uri("http://SharePointserver/_vti_bin/InvoiceServices.svc"));
BasicHttpBinding httpBinding = new BasicHttpBinding();
httpBinding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
httpBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Ntlm;
InvoiceServicesClient myClient = new InvoiceServicesClient(httpBinding, endpoint);
myClient.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;
(call service)
I hope this works for you!
It worked for me:
Products.find({}).then(a => console.log(a.map(p => p.toJSON())))
also if you want use getters, you should add its option also (on defining schema):
new mongoose.Schema({...}, {toJSON: {getters: true}})
//decode base64 string to image
imageBytes = Base64.decode(encodedImage, Base64.DEFAULT);
Bitmap decodedImage = BitmapFactory.decodeByteArray(imageBytes, 0, imageBytes.length);
image.setImageBitmap(decodedImage);
//setImageBitmap is imp
Basically Implement the interface to communicate between Activity and fragment.
1) Main activty
public class MainActivity extends Activity implements SendFragment.StartCommunication
{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public void setComm(String msg) {
// TODO Auto-generated method stub
DisplayFragment mDisplayFragment = (DisplayFragment)getFragmentManager().findFragmentById(R.id.fragment2);
if(mDisplayFragment != null && mDisplayFragment.isInLayout())
{
mDisplayFragment.setText(msg);
}
else
{
Toast.makeText(this, "Error Sending Message", Toast.LENGTH_SHORT).show();
}
}
}
2) sender fragment (fragment-to-Activity)
public class SendFragment extends Fragment
{
StartCommunication mStartCommunicationListner;
String msg = "hi";
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View mView = (View) inflater.inflate(R.layout.send_fragment, container);
final EditText mEditText = (EditText)mView.findViewById(R.id.editText1);
Button mButton = (Button) mView.findViewById(R.id.button1);
mButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
msg = mEditText.getText().toString();
sendMessage();
}
});
return mView;
}
interface StartCommunication
{
public void setComm(String msg);
}
@Override
public void onAttach(Activity activity) {
// TODO Auto-generated method stub
super.onAttach(activity);
if(activity instanceof StartCommunication)
{
mStartCommunicationListner = (StartCommunication)activity;
}
else
throw new ClassCastException();
}
public void sendMessage()
{
mStartCommunicationListner.setComm(msg);
}
}
3) receiver fragment (Activity-to-fragment)
public class DisplayFragment extends Fragment
{
View mView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
mView = (View) inflater.inflate(R.layout.display_frgmt_layout, container);
return mView;
}
void setText(String msg)
{
TextView mTextView = (TextView) mView.findViewById(R.id.textView1);
mTextView.setText(msg);
}
}
I used this link for the same solution, I hope somebody will find it usefull. Very simple and basic example.
http://infobloggall.com/2014/06/22/communication-between-activity-and-fragments/
instead of onkeypress, use onkeydown.
<input type="text" onkeydown="if(event.ctrlKey && event.keyCode==86){return false;}" name="txt">
The starting of react app is based on the main bundle download. React app only starts after the main bundle being downloaded in the browser. This is even true in case of lazy loading architecture. But the fact is we cannot exactly state the name of any bundles. Because webpack will add a hash value at the end of each bundle at the time when you run 'npm run build' command. Of course we can avoid that by changing hash settings, but it will seriously affect the cache data problem in the Browser. Browsers might not take the new version because of the same bundle name. . we need a webpack + js + CSS approach to handle this situation.

UrlConnection is an awkward API to work with. HttpClient is by far the better API and it'll spare you from loosing time searching how to achieve certain things like this stackoverflow question illustrates perfectly. I write this after having used the jdk HttpUrlConnection in several REST clients. Furthermore when it comes to scalability features (like threadpools, connection pools etc.) HttpClient is superior
I used this Unicode Decimal Code ‌
and worked. more details
do wget -r -l0 www.oldsite.com
Then just find www.oldsite.com
would reveal all urls, I believe.
Alternatively, just serve that custom not-found page on every 404 request! I.e. if someone used the wrong link, he would get the page telling that page wasn't found, and making some hints about site's content.
You can check for a network connection in .NET 2.0 using GetIsNetworkAvailable()
:
System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable()
To monitor changes in IP address or changes in network availability use the events from the NetworkChange class:
System.Net.NetworkInformation.NetworkChange.NetworkAvailabilityChanged
System.Net.NetworkInformation.NetworkChange.NetworkAddressChanged
You want to use if statements:
if (liCount === 0) {
setLayoutState('start');
} else if (liCount <= 5) {
setLayoutState('upload1Row');
} else if (liCount <= 10) {
setLayoutState('upload2Rows');

The regular filter options in Excel don't allow for more than 2 criteria settings. To do 2+ criteria settings, you need to use the Advanced Filter option. Below are the steps I did to try this out.
http://www.bettersolutions.com/excel/EDZ483/QT419412321.htm
Set up the criteria. I put this above the values I want to filter. You could do that or put on a different worksheet. Note that putting the criteria in rows will make it an 'OR' filter and putting them in columns will make it an 'AND' filter.
I put the data starting on row 5:
Select the first data row (A6) and click the Advanced Filter option. The List Range should be pre-populated. Select the Criteria range as E1:E4 and click OK.
That should be it. Note that I use the '=' operator. You will want to use something a bit different to test for file extensions.
I found this one more helpful and simple
DECLARE @StartTime datetime,@EndTime datetime
SELECT @StartTime=GETDATE()
--Your Query to be run goes here--
SELECT @EndTime=GETDATE()
SELECT DATEDIFF(ms,@StartTime,@EndTime) AS [Duration in milliseconds]
Just use the length
property of a JavaScript
array like so:
$scope.names.length
Also, I don't see a starting <script>
tag in your code.
If you want the length inside your view, do it like so:
{{ names.length }}
Starting from pandas 0.14 (released end of May 2014), postgresql is supported. The sql
module now uses sqlalchemy
to support different database flavors. You can pass a sqlalchemy engine for a postgresql database (see docs). E.g.:
from sqlalchemy import create_engine
engine = create_engine('postgresql://username:password@localhost:5432/mydatabase')
df.to_sql('table_name', engine)
You are correct that in pandas up to version 0.13.1 postgresql was not supported. If you need to use an older version of pandas, here is a patched version of pandas.io.sql
: https://gist.github.com/jorisvandenbossche/10841234.
I wrote this a time ago, so cannot fully guarantee that it always works, buth the basis should be there). If you put that file in your working directory and import it, then you should be able to do (where con
is a postgresql connection):
import sql # the patched version (file is named sql.py)
sql.write_frame(df, 'table_name', con, flavor='postgresql')
I changed @angular-devkit/build-angular": "0.9.0.1"
to @angular-devkit/build-angular": "0.13.4"
and it worked.
You cannot select on specific values (or types of values). You'd either make a reverse index (map numbers back to (lists of) keys) or you have to loop through all values every time.
If you are processing numbers in arbitrary order anyway, you may as well loop through all items:
for key, value in inputdict.items():
# do something with value
inputdict[key] = newvalue
otherwise I'd go with the reverse index:
from collections import defaultdict
reverse = defaultdict(list)
for key, value in inputdict.items():
reverse[value].append(key)
Now you can look up keys by value:
for key in reverse[value]:
inputdict[key] = newvalue
Example from https://github.com/ffmike/jquery-validate
<label for="spam_email">
<input type="checkbox" class="checkbox" id="spam_email" value="email" name="spam[]" validate="required:true, minlength:2" /> Spam via E-Mail </label>
<label for="spam_phone">
<input type="checkbox" class="checkbox" id="spam_phone" value="phone" name="spam[]" /> Spam via Phone </label>
<label for="spam_mail">
<input type="checkbox" class="checkbox" id="spam_mail" value="mail" name="spam[]" /> Spam via Mail </label>
<label for="spam[]" class="error">Please select at least two types of spam.</label>
The same without field "validate" in tags only using javascript:
$("#testform").validate({
rules: {
"spam[]": {
required: true,
minlength: 1
}
},
messages: {
"spam[]": "Please select at least two types of spam."
}
});
And if you need different names for inputs, you can use somethig like this:
<input type="hidden" name="spam" id="spam"/>
<label for="spam_phone">
<input type="checkbox" class="checkbox" id="spam_phone" value="phone" name="spam_phone" /> Spam via Phone</label>
<label for="spam_mail">
<input type="checkbox" class="checkbox" id="spam_mail" value="mail" name="spam_mail" /> Spam via Mail </label>
Javascript:
$("#testform").validate({
rules: {
spam: {
required: function (element) {
var boxes = $('.checkbox');
if (boxes.filter(':checked').length == 0) {
return true;
}
return false;
},
minlength: 1
}
},
messages: {
spam: "Please select at least two types of spam."
}
});
I have added hidden input before inputs and setting it to "required" if there is no selected checkboxes
Not Equal To
Before C came along and popularized !=
, languages tended to use <>
for not equal to.
At least, the various dialects of Basic did, and they predate C.
An even older and more unusual case is Fortran, which uses .NE.
, as in X .NE. Y

EBS is like the virtual disk of a VM:

From Framework Design Guidelines and FxCop rules.:
1. Custom Exception should have a name that ends with Exception
class MyException : Exception
2. Exception should be public
public class MyException : Exception
3. CA1032: Exception should implements standard constructors.
A serialization constructor protected if the type is not sealed and private if the type is sealed. Based on MSDN:
[Serializable()]
public class MyException : Exception
{
public MyException()
{
// Add any type-specific logic, and supply the default message.
}
public MyException(string message): base(message)
{
// Add any type-specific logic.
}
public MyException(string message, Exception innerException):
base (message, innerException)
{
// Add any type-specific logic for inner exceptions.
}
protected MyException(SerializationInfo info,
StreamingContext context) : base(info, context)
{
// Implement type-specific serialization constructor logic.
}
}
or
[Serializable()]
public sealed class MyException : Exception
{
public MyException()
{
// Add any type-specific logic, and supply the default message.
}
public MyException(string message): base(message)

Alex mentioned memory efficiency, and Roberto mentions convenience, and these are both good points. For a few more ideas, I'll mention speed and functionality.
Functionality: You get a lot built in with NumPy, FFTs, convolutions, fast searching, basic statistics, linear algebra, histograms, etc. And really, who can live without FFTs?
Speed: Here's a test on doing a sum over a list and a NumPy array, showing that the sum on the NumPy array is 10x faster (in this test -- mileage may vary).
from numpy import arange
from timeit import Timer
Nelements = 10000
Ntimeits = 10000
x = arange(Nelements)
y = range(Nelements)
t_numpy = Timer("x.sum()", "from __main__ import x")
t_list = Timer("sum(y)", "from __main__ import y")
print("numpy: %.3e" % (t_numpy.timeit(Ntimeits)/Ntimeits,))
print("list: %.3e" % (t_list.timeit(Ntimeits)/Ntimeits,))
which on my systems (while I'm running a backup) gives:
numpy: 3.004e-05
list: 5.363e-04
The issue was with the dmp file itself. I had to re-export the file and the command works fine. Thank you @Justin Cave
I Abstract Timer away and made it a separate class:
Timer.java
import android.os.Handler;
public class Timer {
IAction action;
Handler timerHandler = new Handler();
int delayMS = 1000;
public Timer(IAction action, int delayMS) {
this.action = action;
this.delayMS = delayMS;
}
public Timer(IAction action) {
this(action, 1000);
}
public Timer() {
this(null);
}
Runnable timerRunnable = new Runnable() {
@Override
public void run() {
if (action != null)
action.Task();
timerHandler.postDelayed(this, delayMS);
}
};
public void start() {
timerHandler.postDelayed(timerRunnable, 0);
}
public void stop() {
timerHandler.removeCallbacks(timerRunnable);
}
}
And Extract main action from Timer
class out as
IAction.java
public interface IAction {
void Task();
}
And I used it just like this:
MainActivity.java
public class MainActivity extends Activity implements IAction{
...
Timer timerClass;
@Override
protected void onCreate(Bundle savedInstanceState) {
...
timerClass = new Timer(this,1000);
timerClass.start();
...
}
...
int i = 1;
@Override
public void Task() {
runOnUiThread(new Runnable() {
@Override
public void run() {
timer.setText(i + "");
i++;
}
});
}
...
}

I think I remember seeing before that if you are updating to the same value SQL Server will actually recognize this and won't do an unnecessary write.
There is a new spec called the Native File System API that allows you to do this properly like this:
const result = await window.chooseFileSystemEntries({ type: "save-file" });
There is a demo here, but I believe it is using an origin trial so it may not work in your own website unless you sign up or enable a config flag, and it obviously only works in Chrome. If you're making an Electron app this might be an option though.
random.sample(population, k)
It is used for randomly sampling a sample of length 'k'
from a population. returns a 'k'
length list of unique elements chosen from the population sequence or set
it returns a new list and leaves the original population unchanged and the resulting list is in selection order so that all sub-slices will also be valid random samples
I am putting up an example in which I am splitting a dataset randomly. It is basically a function in which you pass x_train(population)
as an argument and return indices of 60%
of the data as D_test
.
import random
def randomly_select_70_percent_of_data_from_1_to_length(x_train):
return random.sample(range(0, len(x_train)), int(0.6*len(x_train)))
You can easily create a new tab; do like the following:
function newTab() {
var form = document.createElement("form");
form.method = "GET";
form.action = "http://www.example.com";
form.target = "_blank";
document.body.appendChild(form);
form.submit();
}
Pretty late to the party, but I was struck here and got help from a friend. The thing was not to use PowerMock. This works with the latest version of Mockito.
Mockito comes with this org.mockito.internal.util.reflection.FieldSetter
.
What it basically does is helps you modify private fields using reflection.
This is how you use it:
@Mock
private Person mockedPerson;
private Test underTest;
// ...
@Test
public void testMethod() {
FieldSetter.setField(underTest, underTest.getClass().getDeclaredField("person"), mockedPerson);
// ...
verify(mockedPerson).someMethod();
}
This way you can pass a mock object and then verify it later.
Here is the reference.
If you use .Net 4.5 you can also use standard .Net json serializer:
using System.Runtime.Serialization.Json;
...
Stream jsonSource = ...; // serializer will read data stream
var s = new DataContractJsonSerializer(typeof(string[][]));
var j = (string[][])s.ReadObject(jsonSource);
In .Net 4.5 and older you can use JavaScriptSerializer class:
using System.Web.Script.Serialization;
...
JavaScriptSerializer serializer = new JavaScriptSerializer();
string[][] list = serializer.Deserialize<string[][]>(json);
I was facing the same issue. It worked fine after setting the value for fs.s3n.impl and adding hadoop-aws dependency.
sc.hadoopConfiguration.set("fs.s3n.awsAccessKeyId", awsAccessKeyId)

sc.hadoopConfiguration.set("fs.s3n.impl", "org.apache.hadoop.fs.s3native.NativeS3FileSystem")
You never want to call thread.sleep()
on the UI
thread as it sounds like you have figured out. This freezes the UI
and is always a bad thing to do. You can use a separate Thread
and postDelayed
This SO answer shows how to do that as well as several other options
You can look at these and see which will work best for your particular situation
The name of the public class within a file has to be the same as the name of that file.
So if your file declares class WeatherArray, it needs to be named WeatherArray.java
In my case I got this message because there's a special char (&) in my connectionstring, remove it then everything's good.

I think you approach is correct. Historical table should be a copy of the main table without indexes, make sure you have update timestamp in the table as well.

This should resolve your Gradle issue.. good luck.
Generally, the system displays an ANR if an application cannot respond to user input.
In any situation in which your app performs a potentially lengthy operation, you should not perform the work on the UI thread, but instead create a worker thread and do most of the work there. This keeps the UI thread (which drives the user interface event loop) running and prevents the system from concluding that your code has frozen.
Android applications normally run entirely on a single thread by default the "UI thread" or "main thread"). This means anything your application is doing in the UI thread that takes a long time to complete can trigger the ANR dialog because your application is not giving itself a chance to handle the input event or intent broadcasts.
Therefore, any method that runs in the UI thread should do as little work as possible on that thread. In particular, activities should do as little as possible to set up in key life-cycle methods such as onCreate() and onResume(). Potentially long running operations such as network or database operations, or computationally expensive calculations such as resizing bitmaps should be done in a worker thread (or in the case of databases operations, via an asynchronous request).
private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> {
// Do the long-running work in here
protected Long doInBackground(URL... urls) {
int count = urls.length;
long totalSize = 0;
for (int i = 0; i < count; i++) {
totalSize += Downloader.downloadFile(urls[i]);
publishProgress((int) ((i / (float) count) * 100));
// Escape early if cancel() is called
if (isCancelled()) break;
}
return totalSize;
}
// This is called each time you call publishProgress()
protected void onProgressUpdate(Integer... progress) {
setProgressPercent(progress[0]);
}
// This is called when doInBackground() is finished
protected void onPostExecute(Long result) {
showNotification("Downloaded " + result + " bytes");
}
}
To execute this worker thread, simply create an instance and call execute():
new DownloadFilesTask().execute(url1, url2, url3);

In Java, the two are closely related. This is because Java uses a technique for method invocation called "dynamic dispatch". If I have
public class A {
public void draw() { ... }
public void spin() { ... }
}
public class B extends A {
public void draw() { ... }
public void bad() { ... }
}
...
A testObject = new B();
testObject.draw(); // calls B's draw, polymorphic
testObject.spin(); // calls A's spin, inherited by B
testObject.bad(); // compiler error, you are manipulating this as an A
Then we see that B inherits spin
from A. However, when we try to manipulate the object as if it were a type A, we still get B's behavior for draw
. The draw
behavior is polymorphic.
In some languages, polymorphism and inheritance aren't quite as closely related. In C++, for example, functions not declared virtual are inherited, but won't be dispatched dynamically, so you won't get that polymorphic behavior even when you use inheritance.
In javascript, every function call is dynamically dispatched and you have weak typing. This means you could have a bunch of unrelated objects, each with their own draw
, have a function iterate over them and call the function, and each would behave just fine. You'd have your own polymorphic draw without needing inheritance.
This seems to work as well
SELECT *
FROM makerar m1
WHERE m1.avg = (SELECT MAX(avg)
FROM makerar m2
WHERE m1.cname = m2.cname
)
This works when factor will always be positive:
int round_up(int num, int factor)
{
return num + factor - 1 - (num + factor - 1) % factor;
}
Edit: This returns round_up(0,100)=100
. Please see Paul's comment below for a solution that returns round_up(0,100)=0
.
Those who getting the version issue try this code ..
public static void switchLocal(Context context, String lcode, Activity activity) {
if (lcode.equalsIgnoreCase(""))
return;
Resources resources = context.getResources();
Locale locale = new Locale(lcode);
Locale.setDefault(locale);
android.content.res.Configuration config = new
android.content.res.Configuration();
config.locale = locale;
resources.updateConfiguration(config, resources.getDisplayMetrics());
//restart base activity
activity.finish();
activity.startActivity(activity.getIntent());
}
It will works for all version of twitterbootstrap

One problem it solves: Code simpler than lambda for a call in constructor that uses an output parameter function for initializing a const member
You can initialize a const member of your class, with a call to a function that sets its value by giving back its output as an output parameter.
Here is an example of bubbleSort, and Time Complexity is O(n).
int[] bubbleSort(int[] numbers) {
if(numbers == null || numbers.length == 1) {

isSorted = true;
for(int i = 0; i < numbers.length - 1; i++) {
if(numbers[i] > numbers[i + 1]) {
int hold = numbers[i + 1];
numbers[i + 1] = numbers[i];
numbers[i] = hold;
isSorted = false;

You not only have to add lombok.jar to the libraries, but also install it by either double-clicking the lombok jar, or from the command line run java -jar lombok.jar
. That will show you a nice installer screen. Select your Eclipse installation and install.
Afterwards, you can check if the installer has correctly modified your eclipse.ini:
-vmargs
...
-javaagent:lombok.jar
-Xbootclasspath/a:lombok.jar
If your Eclipse was already running, you have to Exit Eclipse and start it again. (File/Restart is not enough)
If you are starting Eclipse using a shortcut, make sure that either there are no command line arguments filled in, or manually add -javaagent:lombok.jar
-Xbootclasspath/a:lombok.jar
somewhere after -vmargs
.
Recent editions of Lombok also add a line to the About Eclipse screen. If Lombok is active you can find a line like 'Lombok v0.11.6 "Dashing Kakapo" is installed. http://projectlombok.org/' just above the line of buttons.
If for some reason, usually related to customized eclipse builds, you need to use the full path, you can instruct the installer on the command line to do so:
java -Dlombok.installer.fullpath -jar lombok.jar
Go to prompt command and type "adb devices". If it is empty, then make sure you allowed for "MTP Transfer" or similar and you enabled debugging on your phone.
To enable debugging, follow this tutorial: https://www.kingoapp.com/root-tutorials/how-to-enable-usb-debugging-mode-on-android.htm
Then type "adb devices" again. If a device is listed in there, then it should work now.
Instead of using local imports, you may import the entire module instead of the particular object. Then, in your app
module, call mod_login.mod_login

mod_login.py
from app import app

If you use spyder and love GUI, you can simply click on the folder button on the upper right corner of your screen and navigate through folders/directories you want as current directory. After doing so you can go to the file explorer tab of the window in spyder IDE and you can see all the files/folders present there. to check your current working directory go to the console of spyder IDE and simply type
pwd
it will print the same path as you have selected before.
Use:
File file = new File("Z:\\results\\results.txt");
You need to double the backslashes in Windows because the backslash character itself is an escape in Java literal strings.
For POSIX system such as Linux, just use the default file path without doubling the forward slash. this is because forward slash is not a escape character in Java.
File file = new File("/home/userName/Documents/results.txt");
Try like below... it will help you...
