I solved this issue after changing the "Gradle Version" and "Android Plugin version".
You just goto "File>>Project Structure>>Project>>" and make changes here. I have worked a combination of versions from another working project of mine and added to the Project where I was getting this problem.
Not sure if this solution works for you or not but just want to heads you up on compiler and build tools version compatibility issues.
This could be because of Java and Gradle version mismatch.
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip
Gradle 4.4 is compatible with only Java 7 and 8. So, point your global variable JAVA_HOME to Java 7 or 8.
In mac, add below line to your ~/.bash_profile
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_191.jdk/Contents/Home
You can have multiple java versions. Just change the JAVA_HOME path based on need. You can do it easily, check this
My scenario:
old Kotlin dataclass:
data class AddHotelParams(val destination: Place?, val checkInDate: LocalDate,
val checkOutDate: LocalDate?): JsonObject
new Kotlin dataclass:
data class AddHotelParams(val destination: Place?, val checkInDate: LocalDate,
val checkOutDate: LocalDate?, val roundTrip: Boolean): JsonObject
The problem was that I forgot to change the object initialization in some parts of the code. I got a generic "compileInternalDebugKotlin" error instead of being told where I needed to change the initialization.
changing initialization to all parts of the code resolved the error.
Just a simple solution is here...it worked for me:
I have just written this code into gradle.properties and it is ok now
org.gradle.jvmargs=-XX:MaxHeapSize\=2048m -Xmx2048m
PuTTY can't find where your X server is, because you didn't tell it. (ssh on Linux doesn't have this problem because it runs under X so it just uses that one.) Fill in the blank box after "X display location" with your Xming server's address.
Alternatively, try MobaXterm. It has an X server builtin.
also try to increase gradle version in your project's build.gradle. It helped me
I deleted the file with main() function in my project when I wanted to change project type to static library.
I Forgot to change Properties -> General -> Configuration Type
from
Application(.exe)
to
Static Library (.lib)
This too gave me the same error.
You could check if your method is private. Spent a lot of time fixing this dumb mistake ...
I had the same problem.
It was caused by a corrupted file. If you added some new Drawable before getting this error, check them to see if they are correctly display in Android Studio Viewer.
Goto Properties -> maven Remove the pom.xml from the activate profiles and follow the below steps.
Steps :
In my case I just ignored the following in application.properties file:
# Hibernate
#spring.jpa.hibernate.ddl-auto=update
It works for me....
This is for my reference, as I encountered a variety of SQL error messages while trying to connect with provider. Other answers prescribe "try this, then this, then this". I appreciate the other answers, but I like to pair specific solutions with specific problems

I tried some of the suggested answers but it didn't resolve the issue. Finally I found out that the default connection timeout (not command timeout) is 15 seconds and once I increased it to 60 it almost never happened again.
simply add this to you connection string:
;Connection Timeout=60
I chose 60 seconds but you can put any value you think would fit the best to your needs.

I had the same problem. It turned out that I didn't specify a default page and I didn't have any page that is named after the default page convention (default.html, defult.aspx etc). As a result, ASP.NET doesn't allow the user to browse the directory (not a problem in Visual Studio built-in web server that allows you to view the directory) and shows the error message. To fix it, I added one default page in Web.Config and it worked.
<system.webServer>

Yes you are right. You have placed WHERE
clause wrong. You can only use one WHERE
clause in single query so try AND
for multiple conditions like this:
SELECT table1.f_id FROM table1
INNER JOIN table2
ON table2.f_id = table1.f_id
WHERE table2.f_type = 'InProcess'
AND f_com_id = '430'
AND f_status = 'Submitted'

That's because you created a Web Site instead of a Web Application. The cs/vb
files can only be seen in a Web Application, but in a website you can't have a separate cs/vb
file.
Edit: In the website you can add a cs file behavior like..
<%@ Application CodeFile="Global.asax.cs" Inherits="ApplicationName.MyApplication" Language="C#" %>
~/Global.asax.cs:
namespace ApplicationName
{
public partial class MyApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
}
}

Your session is lost becoz....
I have found a scenario where session is lost - In a asp.net page, for a amount text box field has invalid characters, and followed by a session variable retrieval for other purpose.After posting the invalid number parsing through Convert.ToInt32 or double raises a first chance exception, but error does not show at that line, Instead of that, Session being null because of unhandled exception, shows error at session retrieval, thus deceiving the debugging...
HINT: Test your system to fail it- DESTRUCTIVE.. enter enough junk in unrelated scenarios for ex: after search results shown enter junk in search criteria and goto details of search result... , you would be able to reproduce this machine on your local code base too...:)

I had a similar problem with a different cause and therefore different solution. In my case, I actually had an error where a singleton object was having a member variable modified in a non-threadsafe way. In this case, following the accepted answers and circumventing the parallel testing would only hide the error that was actually revealed by the test. My solution, of course, is to fix the design so that I don't have this bad behavior in my code.
If you want to make this part of your POM for a repeatable build, you can use the fork-variant of a few of the plugins (especially compiler:compile and surefire:test):

I had the same issue with setting StatusCode
and then Response.End
in HandleUnauthorizedRequest
method of AuthorizeAttribute
var ctx = filterContext.HttpContext;
ctx.Response.StatusCode = (int)HttpStatusCode.Forbidden;
ctx.Response.End();
If you are using .NET 4.5+, add this line before Response.StatusCode
filterContext.HttpContext.Response.SuppressFormsAuthenticationRedirect = true;
If you are using .NET 4.0, try SuppressFormsAuthenticationRedirectModule.
If you want to set the timeout to 20 minutes, use something like this:
<configuration>
<system.web>
<sessionState timeout="20"></sessionState>
</system.web>
</configuration>
You can use coalesce(column_name,0)
instead of just column_name
. The coalesce
function returns the first non-NULL value in the list.
I should mention that per-row functions like this are usually problematic for scalability. If you think your database may get to be a decent size, it's often better to use extra columns and triggers to move the cost from the select
to the insert/update
.
This amortises the cost assuming your database is read more often than written (and most of them are).
Create listener interface.
public interface YourCustomListener
{
public void onCustomClick(View view);
// pass view as argument or whatever you want.
}
And create method setOnCustomClick in another activity(or fragment) , where you want to apply your custom listener......
public void setCustomClickListener(YourCustomListener yourCustomListener)
{
this.yourCustomListener= yourCustomListener;
}
Call this method from your First activity, and pass the listener interface...
The top rated answers are working perfect (a bit old but still working), but I just want to mention that since Android N we all can configure your apps in order to have diff trust SSL certificates (for release , debug only and so on), including Charles SSL Proxy certificate (if you download the Charles certificate and put .pem file in your raw folder). More info can be found here: https://developer.android.com/training/articles/security-config.html
Also the official Charles documentation can be useful to setup this : https://www.charlesproxy.com/documentation/using-charles/ssl-certificates/
Hope this will help to setup Charles inside your app project not on every single Android device.
git reset --hard origin/master
says: throw away all my staged and unstaged changes, forget everything on my current local branch and make it exactly the same as origin/master
.
You probably wanted to ask this before you ran the command. The destructive nature is hinted at by using the same words as in "hard reset".
For the sake of anyone also using visual studio from a windows environment:
I realized that I could see my module installed when i ran pip install
py pip install [moduleName]
py pip list
However debugging in visual studio was getting "module not found". Oddly, i was successfully running import [moduleName]
when i ran the interpreter in powershell.
Reason:
visual studio was using the wrong interpreter at:
C:\Users\[username]\AppData\Local\Programs\Python\Python37\
What I REALLY wanted was visual studio to use the virtualenv that i setup for my project. To do this, right click Python Environments in "solution explorer", select Add Virtual Environment..., and then select the folder where you created your virtual environment. Then, under project settings, under the General tab, select your virtual environment in the dropdown.
Now visual studio should be using the same interpreter and everything should play nice!
Could I suggest, if you're okay with this being limited to html 5 compliant browsers, simply using:
<input type="search" />
Admittedly, in Chromium (Ubuntu 11.04), this does require there to be text inside the input
element before the clear-text image/functionality will appear.

Something has deleted your ibdata1 file where InnoDB keeps the dictionary. Definitely it's not MySQL who does it.

seems the way to go, but for what it's worth, the figure
has a transFigure
property that you can use:
fig=figure(1)
text(0.5, 0.95, 'test', transform=fig.transFigure, horizontalalignment='center')
If you are using Spring as Back-End server and especially using Spring Security then i found a solution by putting http.cors();
in the configure
method. The method looks like that:
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.authorizeRequests() // authorize
.anyRequest().authenticated() // all requests are authenticated
.and()
.httpBasic();
http.cors();
}
I am using EPPlus to generate .xlsx (OpenXML format based) excel file. For sending this excel file as attachment in email I use the following MIME type and it works fine with EPPlus generated file and opens properly in ms-outlook mail client preview.
string mimeType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
System.Net.Mime.ContentType contentType = null;
if (mimeType?.Length > 0)
{
contentType = new System.Net.Mime.ContentType(mimeType);
}
Do you have a pointer to a vector because that's how you've coded it? You may want to reconsider this and use a (possibly const) reference. For example:
#include <iostream>
#include <vector>
using namespace std;
void foo(vector<int>* a)
{
cout << a->at(0) << a->at(1) << a->at(2) << endl;
// expected result is "123"
}
int main()
{
vector<int> a;
a.push_back(1);
a.push_back(2);
a.push_back(3);
foo(&a);
}
While this is a valid program, the general C++ style is to pass a vector by reference rather than by pointer. This will be just as efficient, but then you don't have to deal with possibly null pointers and memory allocation/cleanup, etc. Use a const reference if you aren't going to modify the vector, and a non-const reference if you do need to make modifications.
Here's the references version of the above program:
#include <iostream>
#include <vector>
using namespace std;
void foo(const vector<int>& a)
{
cout << a[0] << a[1] << a[2] << endl;
// expected result is "123"
}
int main()
{
vector<int> a;
a.push_back(1);
a.push_back(2);
a.push_back(3);
foo(a);
}
As you can see, all of the information contained within a will be passed to the function foo, but it will not copy an entirely new value, since it is being passed by reference. It is therefore just as efficient as passing by pointer, and you can use it as a normal value rather than having to figure out how to use it as a pointer or having to dereference it.
On Visual Studio Community 7.5.3 on Mac this works for me:
Ctrl + Space
You need to create it. In most installations I've used it hasn't been created by default.
You usually create it as ~/.vimrc
.
You can customize the deserialization for any attribute.
Declare your deserialize class using the annotationJsonDeserialize (import com.fasterxml.jackson.databind.annotation.JsonDeserialize
) for the attribute that will be processed. If this is an Enum:
@JsonDeserialize(using = MyEnumDeserialize.class)
private MyEnum myEnum;
This way your class will be used to deserialize the attribute. This is a full example:
public class MyEnumDeserialize extends JsonDeserializer<MyEnum> {
@Override
public MyEnum deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException {
JsonNode node = jsonParser.getCodec().readTree(jsonParser);
MyEnum type = null;
try{
if(node.get("attr") != null){
type = MyEnum.get(Long.parseLong(node.get("attr").asText()));
if (type != null) {
return type;
}
}
}catch(Exception e){
type = null;
}
return type;
}
}
michal.kreuzman nice one I will have to say. It was useful.
However, the above works only for single digits: if you are going to use more than one digit, the structure is going to get misplaced since you are using spaces and not tabs.
As for my later codes I needed more digits than only 2, so I made a program myself.
It has some bugs now, again right now I am feeling lazy to correct them but it prints very beautifully and the nodes can take a larger number of digits.
The tree is not going to be as the question mentions but it is 270 degrees rotated :)
public static void printBinaryTree(TreeNode root, int level){
if(root==null)
return;
printBinaryTree(root.right, level+1);
if(level!=0){
for(int i=0;i<level-1;i++)
System.out.print("|\t");
System.out.println("|-------"+root.val);
}
else
System.out.println(root.val);
printBinaryTree(root.left, level+1);
}
Place this function with your own specified TreeNode and keep the level initially 0, and enjoy!
Here are some of the sample outputs:
| | |-------11
| |-------10
| | |-------9

Only problem is with the extending branches; I will try to solve the problem as soon as possible but till then you can use it too.
I recently run into this problem, when trying to count using case when
, and found that changing the order of the which
and count
statements fixes the problem:
SELECT date(dateday) as pick_day,
COUNT(CASE WHEN (apples = 'TRUE' OR oranges 'TRUE') THEN fruit END) AS fruit_counter
FROM pickings
GROUP BY 1
Instead of using - in the latter, where I got errors that apples and oranges should appear in aggregate functions
CASE WHEN ((apples = 'TRUE' OR oranges 'TRUE') THEN COUNT(*) END) END AS fruit_counter
Maybe it is easier to convert the Date into the actual integer 20110506105524
and then convert this into a string:
function printDate() {
var temp = new Date();
var dateInt =
((((temp.getFullYear() * 100 +
temp.getMonth() + 1) * 100 +
temp.getDate()) * 100 +
temp.getHours()) * 100 +
temp.getMinutes()) * 100 +
temp.getSeconds();
debug ( '' + dateInt ); // convert to String
}
When temp.getFullYear() < 1000
the result will be one (or more) digits shorter.
Caution: this wont work with millisecond precision (i.e. 17 digits) since Number.MAX_SAFE_INTEGER is 9007199254740991
which is only 16 digits.
Being in "detached head" means that HEAD refers to a specific unnamed commit (as opposite to a named branch) (cf: https://git-scm.com/docs/git-checkout section Detached head)
To fix the problem, you only need to select the branch that was selected before by
git checkout @{-1}
(magento 2 example provided below)
sectionName, groupName and fieldName are present in etc/system.xml file of the module.
PHP Syntax:
Mage::getStoreConfig('sectionName/groupName/fieldName');
From within an editor in the admin, such as the content of a CMS Page or Static Block; the description/short description of a Catalog Category, Catalog Product, etc.
{{config path="sectionName/groupName/fieldName"}}
For the "Within an editor" approach to work, the field value must be passed through a filter for the {{ ... }} contents to be parsed out. Out of the box, Magento will do this for Category and Product descriptions, as well as CMS Pages and Static Blocks. However, if you are outputting the content within your own custom view script and want these variables to be parsed out, you can do so like this:
<?php
$example = Mage::getModel('identifier/name')->load(1);
$filter = Mage::getModel('cms/template_filter');
echo $filter->filter($example->getData('field'));
?>
Replacing identifier/name with the a appropriate values for the model you are loading, and field with the name of the attribute you want to output, which may contain {{ ... }} occurrences that need to be parsed out.
From any Block class that extends \Magento\Framework\View\Element\AbstractBlock
$this->_scopeConfig->getValue('sectionName/groupName/fieldName');
Any other PHP class:
If the class (and none of it's parent's) does not inject \Magento\Framework\App\Config\ScopeConfigInterface
via the constructor, you'll have to add it to your class.
// ... Remaining class definition above...
/**
* @var \Magento\Framework\App\Config\ScopeConfigInterface
*/
protected $_scopeConfig;
/**
* Constructor
*/
public function __construct(
\Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig
// ...any other injected classes the class depends on...
) {
$this->_scopeConfig = $scopeConfig;
// Remaining constructor logic...
}
// ...remaining class definition below...
Once you have injected it into your class, you can now fetch store configuration values with the same syntax example given above for block classes.
Note that after modifying any class's __construct() parameter list, you may have to clear your generated classes as well as dependency injection directory: var/generation
& var/di
You didn't specify how the order is determined, but this will give you a rank value in MySQL:
SELECT t.*,
@rownum := @rownum +1 AS rank
FROM TBL_FOO t
JOIN (SELECT @rownum := 0) r
WHERE t.name = 'sarmen'
Then you can pick out what rows you want, based on the rank value.

I found a problem with Tobias Cohen's code (I don't have enough points to comment on it directly), which otherwise works for me. If you have two select options with the same name, both with value="", the original code will produce "name":"" instead of "name":["",""]
I think this can fixed by adding " || o[this.name] == ''" to the first if condition:
$.fn.serializeObject = function()
{
var o = {};
var a = this.serializeArray();
$.each(a, function() {
if (o[this.name] || o[this.name] == '') {
if (!o[this.name].push) {
o[this.name] = [o[this.name]];
}
o[this.name].push(this.value || '');
} else {
o[this.name] = this.value || '';
}
});
return o;
};
The accepted answer is a bad idea in general because the manually created make.exe
will stick around and can potentially cause unexpected problems. It actually breaks RubyInstaller: https://github.com/oneclick/rubyinstaller2/issues/105
An alternative is installing make via Chocolatey (as pointed out by @Vasantha Ganesh K)
Another alternative is installing MSYS2 from Chocolatey and using make
from C:\tools\msys64\usr\bin
. If make
isn't installed automatically with MSYS2 you need to install it manually via pacman -S make
(as pointed out by @Thad Guidry and @Luke).
I think my solution is more simple with default functionality.

How about using backslash \
in front of the square bracket. Normally square brackets match a character class.
another solution using dplyr is:
df <- ## your data ##
df <- df %>%
mutate(Den = ifelse(any(is.na(Den)) | any(Den != 1), 0, 1))
Most answers based on (a1 - a2) or (a1 & a2) would not work if there are duplicate elements in either array. I arrived here looking for a way to see if all letters of a word (split to an array) were part of a set of letters (for scrabble for example). None of these answers worked, but this one does:
def contains_all?(a1, a2)
try = a1.chars.all? do |letter|
a1.count(letter) <= a2.count(letter)
end
return try
end
From Dockerfile reference:
The
ARG
instruction defines a variable that users can pass at build-time to the builder with the docker build command using the--build-arg <varname>=<value>
flag.The
ENV
instruction sets the environment variable<key>
to the value<value>
.
The environment variables set usingENV
will persist when a container is run from the resulting image.
So if you need build-time customization, ARG
is your best choice.
If you need run-time customization (to run the same image with different settings), ENV
is well-suited.
If I want to add let's say 20 (a random number) of extensions or any other feature that can be enable|disable
Given the number of combinations involved, using ENV
to set those features at runtime is best here.
But you can combine both by:
ARG
ARG
as an ENV
That is, with a Dockerfile including:
ARG var
ENV var=${var}
You can then either build an image with a specific var
value at build-time (docker build --build-arg var=xxx
), or run a container with a specific runtime value (docker run -e var=yyy
)

# Strip all extensions
# by stripping out longest trailing match of dot followed by anything

# Printout demo
printf %s\\n "$path" "$dirname" "$basename" "$oneextless" "$noext"

Pagination is generally a "user" operation and to prevent overload both on computers and the human brain you generally give a subset. However, rather than thinking that we don't get the whole list it may be better to ask does it matter?
If an accurate live scrolling view is needed, REST APIs which are request/response in nature are not well suited for this purpose. For this you should consider WebSockets or HTML5 Server-Sent Events to let your front end know when dealing with changes.
Now if there's a need to get a snapshot of the data, I would just provide an API call that provides all the data in one request with no pagination. Mind you, you would need something that would do streaming of the output without temporarily loading it in memory if you have a large data set.
For my case I implicitly designate some API calls to allow getting the whole information (primarily reference table data). You can also secure these APIs so it won't harm your system.

You can't really do what you want with a dictionary. You already have the dictionary d = {'ac':33, 'gw':20, 'ap':102, 'za':321, 'bs':10}
created. I found there was no way to keep in order once it is already created. What I did was make a json file instead with the object:
{"ac":33,"gw":20,"ap":102,"za":321,"bs":10}
I used:
r = json.load(open('file.json'), object_pairs_hook=OrderedDict)
then used:
print json.dumps(r)
to verify.
For what it's worth, my groovy spike seems to work with both UTF-8 and ISO-8859-1 character encodings. Not sure what will happen when a non zxing decoder tries to decode the UTF-8 encoded image though... probably varies depending on the device.

It generally it helps to avoid SQL injection, for example consider the following code:
<?php
// Query database to check if there are any matching users
$query = "SELECT * FROM users WHERE user='{$_POST['username']}' AND password='{$_POST['password']}'";
mysql_query($query);
// We didn't check $_POST['password'], it could be anything the user wanted! For example:
$_POST['username'] = 'aidan';
$_POST['password'] = "' OR ''='";
// This means the query sent to MySQL would be:
echo $query;
?>
and a hacker can send a query like:
SELECT * FROM users WHERE user='aidan' AND password='' OR ''=''
This would allow anyone to log in without a valid password.
console.dir() is the most direct way.
ANSWER AS OF June 2019
Install the XML Tools
plugin from the Plugin Admin (in Notepad++ 7.7 at least)
Then click Plugins -> XML Tools -> Pretty Print (XML Only with Line breaks)
That did it for me.
There is nothing particularly tricky about the example you posted.
In a ternary operator, the first argument (the conditional) is evaluated and if the result is true
, the second argument is evaluated and returned, otherwise, the third is evaluated and returned. Each of those arguments can be any valid code block, including function calls.
Think of it this way:
var x = (1 < 2) ? true : false;
Could also be written as:
var x = (1 < 2) ? getTrueValue() : getFalseValue();
This is perfectly valid, and those functions can contain any arbitrary code, whether it is related to returning a value or not. Additionally, the results of the ternary operation don't have to be assigned to anything, just as function results do not have to be assigned to anything:
(1 < 2) ? getTrueValue() : getFalseValue();
Now simply replace those with any arbitrary functions, and you are left with something like your example:
(1 < 2) ? removeItem($this) : addItem($this);
Now your last example really doesn't need a ternary at all, as it can be written like this:
x = (1 < 2); // x will be set to "true"
radiobuttonlist.selected <value>
to process with your code.

Yes, it is. Declare parameter as so:
@Sort varchar(50) = NULL
Now you don't even have to pass the parameter in. It will default to NULL (or whatever you choose to default to).

You can try my ServiceStack JsonSerializer it's the fastest .NET JSON serializer at the moment. It supports serializing DataContract's, Any POCO Type, Interfaces, Late-bound objects including anonymous types, etc.
Basic Example
var customer = new Customer { Name="Joe Bloggs", Age=31 };
var json = customer.ToJson();
var fromJson = json.FromJson<Customer>();
Note: Only use Microsofts JavaScriptSerializer if performance is not important to you as I've had to leave it out of my benchmarks since its up to 40x-100x slower than the other JSON serializers.
For anyone looking here for new Socket.io (3.x) the migration documents are fairly helpful.
In particular this snippet:
const io = require("socket.io")(httpServer, {
cors: {
origin: "https://example.com",
methods: ["GET", "POST"],
allowedHeaders: ["my-custom-header"],
credentials: true
}
});
Edit: The original link I answered with is now invalid.The newer URL would be https://developers.google.com/web/tools/chrome-devtools/javascript/add-breakpoints#exceptions as of 2016-11-11.
I realize this question has an answer, but it's no longer accurate. Use the link above ^
(link replaced by edited above) - you can now set it to break on all exceptions or just unhandled ones. (Note that you need to be in the Sources tab to see the button.)
Chrome's also added some other really useful breakpoint capabilities now, such as breaking on DOM changes or network events.
Normally I wouldn't re-answer a question, but I had the same question myself, and I found this now-wrong answer, so I figured I'd put this information in here for people who came along later in searching. :)
A better (IMO) one-line approach, works on ExtJS 4, not sure about 3:

Here is a simple recursive algorithm in python for finding all subsets of a set:
def find_subsets(so_far, rest):
print 'parameters', so_far, rest
if not rest:
print so_far
else:
find_subsets(so_far + [rest[0]], rest[1:])
find_subsets(so_far, rest[1:])
find_subsets([], [1,2,3])
The output will be the following: $python subsets.py
parameters [] [1, 2, 3]
parameters [1] [2, 3]
parameters [1, 2] [3]
parameters [1, 2, 3] []
[1, 2, 3]

Use iloc to access by position (rather than label):
In [11]: df = pd.DataFrame([[1, 2], [3, 4]], ['a', 'b'], ['A', 'B'])
In [12]: df
Out[12]:
A B
a 1 2
b 3 4
In [13]: df.iloc[0] # first row in a DataFrame
Out[13]:
A 1
B 2
Name: a, dtype: int64
In [14]: df['A'].iloc[0] # first item in a Series (Column)
Out[14]: 1
You could do the following:
pg_dump -h <host ip address> -U <host db user name> -t <host table> > <host database> | psql -h localhost -d <local database> -U <local db user>
Actually, I believe this would be the fastest:
SELECT ProductID, ProductName
FROM Northwind..Products p
outer join Northwind..[Order Details] od on p.ProductId = od.ProductId)
WHERE od.ProductId is null
SELECT name
FROM sys.objects
WHERE type = 'P'
AND (DATEDIFF(D,modify_date, GETDATE()) < 7
OR DATEDIFF(D,create_date, GETDATE()) < 7)
You can use span
elements instead of the br
if you want the white space method to work, as it depends on pseudo-elements which are "not defined" for replaced elements.
HTML
<p>
To break lines<span class="line-break">in a paragraph,</span><span>don't use</span><span>the 'br' element.</span>
</p>
CSS
span {white-space: pre;}
span:after {content: ' ';}
span.line-break {display: block;}
span.line-break:after {content: none;}
The line break is simply achieved by setting the appropriate span element to display:block
.
By using IDs and/ or Classes in your HTML markup you can easily target every single or combination of span elements by CSS or use CSS selectors like nth-child()
.
So you can e.g. define different break points by using media queries for a responsive layout.
And you can also simply add/ remove/ toggle classes by Javascript (jQuery).
The "advantage" of this method is its robustness - works in every browser that supports pseudo-elements (see: Can I use - CSS Generated content).
As an alternative it is also possible to add a line break via pseudo-elements:
span.break:before {
content: "\A";
white-space: pre;
}
Just to be clear, This still have to be tested more...

Use ssh-add command to add your public key to the ssh-agent.
ssh-add
Make sure the ssh public key e.g. ~/.ssh/id_rsa.pub is what you have in your repo settings.
Make sure you can actually ssh into the server e.g. For Bitbucket:
ssh -T [email protected]
Update the url to move from https to ssh. You can check which you use by checking the output of:
git remote -v
If you see a https:// in the urls, then you are still using https. To update it: Take the url and just replace https:// with ssh:// e.g. Change:
https://[email protected]/../..
To:
ssh://[email protected]/../..
Referenced: https://docs.github.com/en/github/using-git/changing-a-remotes-url#switching-remote-urls-from-https-to-ssh

If there is a failed merge, which is the most common reason for wanting to undo a git pull
, running git reset --merge
does exactly what one would expect: keep the fetched files, but undo the merge that git pull
attempted to merge. Then one can decide what to do without the clutter that git merge
sometimes generates. And it does not need one to find the exact commit ID which --hard
mentioned in every other answer requires.

It is possible to use Symfony\Component\Console\Output\TrimmedBufferOutput
and then test the buffered output string like this:
use Symfony\Component\Console\Output\TrimmedBufferOutput;
//...
public function testSomething()

$output = new TrimmedBufferOutput(999);
$output->writeln('Do something in your code with the output class...');
//test the output:
$this->assertStringContainsString('expected string...', $output->fetch());
}
Try this:
function GetDateFormat(controlName) {
if ($('#' + controlName).val() != "") {
var d1 = Date.parse($('#' + controlName).val().toString().replace(/([0-9]+)\/([0-9]+)/,'$2/$1'));
if (d1 == null) {
alert('Date Invalid.');
$('#' + controlName).val("");
}
var array = d1.toString('dd-MMM-yyyy');
$('#' + controlName).val(array);
}
}
The RegExp replace .replace(/([0-9]+)\/([0-9]+)/,'$2/$1')
change day/month position.
Try this regular expression:
\w*Id\b
\w*
allows word characters in front of Id
and the \b

First, here's some sample data:

three = rnorm(15),
four = runif(15))
dat <- data.frame(lapply(dat, function(x) { x[sample(15, 5)] <- NA; x }))
head(dat)
# one two three four
# 1 NA M 0.80418951 0.8921983
# 2 0.1836433 O -0.05710677 NA

# 6 -0.8204684 <NA> -1.28459935 0.4346595
Here's our replacement:
dat[["four"]][is.na(dat[["four"]])] <- 0
head(dat)
# one two three four
# 1 NA M 0.80418951 0.8921983
# 2 0.1836433 O -0.05710677 0.0000000

# 6 -0.8204684 <NA> -1.28459935 0.4346595
Alternatively, you can, of course, write dat$four[is.na(dat$four)] <- 0

Simply you can read XML file as dataType: "xml", it will retuen xml object already parsed. you can use it as jquery object and find anything or loop throw it…etc.
$(document).ready(function(){
$.ajax({

dataType: "xml" ,
success: function(xml) {
//var xmlDoc = $.parseXML( xml ); <------------------this line
//if single item
var person = $(xml).find('person').text();
//but if it's multible items then loop
$(xml).find('person').each(function(){
$("#temp").append('<li>' + $(this).text() + '</li>');
});
}
});
});
First, you need to obtain the public certificate from the server you're trying to connect to. That can be done in a variety of ways, such as contacting the server admin and asking for it, using OpenSSL to download it, or, since this appears to be an HTTP server, connecting to it with any browser, viewing the page's security info, and saving a copy of the certificate. (Google should be able to tell you exactly what to do for your specific browser.)
Now that you have the certificate saved in a file, you need to add it to your JVM's trust store. At $JAVA_HOME/jre/lib/security/
for JREs or $JAVA_HOME/lib/security
for JDKs, there's a file named cacerts
, which comes with Java and contains the public certificates of the well-known Certifying Authorities. To import the new cert, run keytool as a user who has permission to write to cacerts:
keytool -import -file <the cert file> -alias <some meaningful name> -keystore <path to cacerts file>
It will most likely ask you for a password. The default password as shipped with Java is changeit
. Almost nobody changes it. After you complete these relatively simple steps, you'll be communicating securely and with the assurance that you're talking to the right server and only the right server (as long as they don't lose their private key).
RouterModule.forRoot([
{ path: 'welcome', component: WelcomeComponent },
{ path: '', redirectTo: 'welcome', pathMatch: 'full' },
{ path: '**', component: 'pageNotFoundComponent' }
])
Case 1 pathMatch:'full'
:
In this case, when app is launched on localhost:4200
(or some server) the default page will be welcome screen, since the url will be https://localhost:4200/
If https://localhost:4200/gibberish
this will redirect to pageNotFound screen because of path:'**'
wildcard
Case 2
pathMatch:'prefix'
:
If the routes have { path: '', redirectTo: 'welcome', pathMatch: 'prefix' }
, now this will never reach the wildcard route since every url would match path:''
defined.

string foo = @"D:\Projects\Some\Kind\Of\Pathproblem\wuhoo.xml";
The problem is that in a string, a \
is an escape character. By using the @
sign you tell the compiler to ignore the escape characters.
You can also get by with escaping the \
:
string foo = "D:\\Projects\\Some\\Kind\\Of\\Pathproblem\\wuhoo.xml";
In general the point of the SettingWithCopyWarning
is to show users (and especially new users) that they may be operating on a copy and not the original as they think. There are false positives (IOW if you know what you are doing it could be ok). One possibility is simply to turn off the (by default warn) warning as @Garrett suggest.
Here is another option:
In [1]: df = DataFrame(np.random.randn(5, 2), columns=list('AB'))
In [2]: dfa = df.ix[:, [1, 0]]
In [3]: dfa.is_copy
Out[3]: True
In [4]: dfa['A'] /= 2
/usr/local/bin/ipython:1: SettingWithCopyWarning: A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_index,col_indexer] = value instead
#!/usr/local/bin/python
You can set the is_copy
flag to False
, which will effectively turn off the check, for that object:
In [5]: dfa.is_copy = False
In [6]: dfa['A'] /= 2
If you explicitly copy then no further warning will happen:
In [7]: dfa = df.ix[:, [1, 0]].copy()
In [8]: dfa['A'] /= 2
The code the OP is showing above, while legitimate, and probably something I do as well, is technically a case for this warning, and not a false positive. Another way to not have the warning would be to do the selection operation via reindex
, e.g.
quote_df = quote_df.reindex(columns=['STK', ...])
Or,
quote_df = quote_df.reindex(['STK', ...], axis=1) # v.0.21
Java's URI Class can help you out of this:
public static String getCurrentUrl(HttpServletRequest request){
URL url = new URL(request.getRequestURL().toString());
String host = url.getHost();
String userInfo = url.getUserInfo();
String scheme = url.getProtocol();
String port = url.getPort();
String path = request.getAttribute("javax.servlet.forward.request_uri");
String query = request.getAttribute("javax.servlet.forward.query_string");
URI uri = new URI(scheme,userInfo,host,port,path,query,null)
return uri.toString();
}
Update The currently suggested way to start a Task is simply using Task.Run()
Task.Run(() => foo());
Note that this method is described as the best way to start a task see here
Previous answer
I like the Task Factory from System.Threading.Tasks. You can do something like this:
Task.Factory.StartNew(() =>
{
// Whatever code you want in your thread
});
Note that the task factory gives you additional convenience options like ContinueWith:
Task.Factory.StartNew(() => {}).ContinueWith((result) =>
{
// Whatever code should be executed after the newly started thread.
});
Also note that a task is a slightly different concept than threads. They nicely fit with the async/await keywords, see here.
I just use a bit of jQuery/javascript:
html:
<h1>Don't Print</h1>
<a data-target="#myModal" role="button" class="btn" data-toggle="modal">Launch modal</a>
<div class="modal fade hide" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Modal to print</h3>
</div>
<div class="modal-body">
<p>Print Me</p>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
<button class="btn btn-primary" id="printButton">Print</button>
</div>
</div>
js:
$('#printButton').on('click', function () {
if ($('.modal').is(':visible')) {
var modalId = $(event.target).closest('.modal').attr('id');
$('body').css('visibility', 'hidden');
$("#" + modalId).css('visibility', 'visible');
$('#' + modalId).removeClass('modal');
window.print();
$('body').css('visibility', 'visible');
$('#' + modalId).addClass('modal');
} else {
window.print();
}
});

format
The following is excerpt from the documentation:
Given
format % values
,%
conversion specifications informat
are replaced with zero or more elements ofvalues
. The effect is similar to the usingsprintf()
in the C language.If
format
requires a single argument, values may be a single non-tuple object. Otherwise, values must be a tuple with exactly the number of items specified by theformat
string, or a single mapping object (for example, a dictionary).
str.format
instead of %
A newer alternative to %
operator is to use str.format
. Here's an excerpt from the documentation:
str.format(*args, **kwargs)
Perform a string formatting operation. The string on which this method is called can contain literal text or replacement fields delimited by braces
{}
. Each replacement field contains either the numeric index of a positional argument, or the name of a keyword argument. Returns a copy of the string where each replacement field is replaced with the string value of the corresponding argument.This method is the new standard in Python 3.0, and should be preferred to
%
formatting.
Here are some usage examples:
>>> '%s for %s' % ("tit", "tat")
tit for tat
>>> '{} and {}'.format("chicken", "waffles")
chicken and waffles
>>> '%(last)s, %(first)s %(last)s' % {'first': "James", 'last': "Bond"}
Bond, James Bond
>>> '{last}, {first} {last}'.format(first="James", last="Bond")
Bond, James Bond

In my case, it started hapenning after I updated to Android Studio 1.2. To fix it I just had to remove "\bin" from my JAVA_HOME variable.
I'm using the "Trim Right Whitespace" exactly working on my "Show-Grp-of-UID.CMD". :) Other idea for improvement are welcome.. ^_^
Since SHA-1 maps several byte sequences to one, you can't "decrypt" a hash, but in theory you can find collisions: strings that have the same hash.
It seems that breaking a single hash would cost about 2.7 million dollars worth of computer time currently, so your efforts are probably better spent somewhere else.
<ion-col size="12">
<ion-card class="box-shadow ion-text-center background-size"
*ngIf="data != null"
[ngStyle]="{'background-image': 'url(' + data.headerImage + ')'}">
</ion-card>
You can use the ElementAt extension method on the list.
For example:
// Get the first item from the list
using System.Linq;
var myList = new List<string>{ "Yes", "No", "Maybe"};
var firstItem = myList.ElementAt(0);
// Do something with firstItem
The Best Solution I found is below:
onSavedInstanceState(): always called inside fragment when activity is going to shut down(Move activity from one to another or config changes). So if we are calling multiple fragments on same activity then We have to use the following approach:
Use OnDestroyView() of the fragment and save the whole object inside that method. Then OnActivityCreated(): Check that if object is null or not(Because this method calls every time). Now restore state of an object here.
Its works always!
Some plugins require one to run as an Administrator
and will not load unless one has those credentials active in the shell.
Assuming that your Sheet1
is not necessary active you would need to use this improved code of yours:
i = ActiveWorkbook.Worksheets("Sheet1").Range("A2" , Worksheets("Sheet1").Range("A2").End(xlDown)).Rows.Count
Look into full worksheet reference for second argument for Range(arg1, arg2)
which important in this situation.
It's always problematic and often misleading to try and translate constructs and concepts between languages. Casting is no exception. Particularly because Java is a dynamic language and C++ is somewhat different.
All casting in Java, no matter how you do it, is done at runtime. Type information is held at runtime. C++ is a bit more of a mix. You can cast a struct in C++ to another and it's merely a reinterpretation of the bytes that represent those structs. Java doesn't work that way.
Also generics in Java and C++ are vastly different. Don't concern yourself overly with how you do C++ things in Java. You need to learn how to do things the Java way.
I mentioned this in a comment on the other question, but the whole idea of Inversion of Control is to have none of your classes know or care how they get the objects they depend on. This makes it easy to change what type of implementation of a given dependency you use at any time. It also makes the classes easy to test, as you can provide mock implementations of dependencies. Finally, it makes the classes simpler and more focused on their core responsibility.
Calling ApplicationContext.getBean()
is not Inversion of Control! While it's still easy to change what implemenation is configured for the given bean name, the class now relies directly on Spring to provide that dependency and can't get it any other way. You can't just make your own mock implementation in a test class and pass that to it yourself. This basically defeats Spring's purpose as a dependency injection container.
Everywhere you want to say:
MyClass myClass = applicationContext.getBean("myClass");
you should instead, for example, declare a method:
public void setMyClass(MyClass myClass) {
this.myClass = myClass;
}
And then in your configuration:
<bean id="myClass" class="MyClass">...</bean>
<bean id="myOtherClass" class="MyOtherClass">
<property name="myClass" ref="myClass"/>
</bean>
Spring will then automatically inject myClass
into myOtherClass
.
Declare everything in this way, and at the root of it all have something like:
<bean id="myApplication" class="MyApplication">
<property name="myCentralClass" ref="myCentralClass"/>
<property name="myOtherCentralClass" ref="myOtherCentralClass"/>
</bean>
MyApplication
is the most central class, and depends at least indirectly on every other service in your program. When bootstrapping, in your main
method, you can call applicationContext.getBean("myApplication")
but you should not need to call getBean()
anywhere else!
You can use the built-in forEach
function for arrays.
Like this:
//this sets all product descriptions to a max length of 10 characters
data.products.forEach( (element) => {
element.product_desc = element.product_desc.substring(0,10);
});
Your version wasn't wrong though. It should look more like this:
for(let i=0; i<data.products.length; i++){
console.log(data.products[i].product_desc); //use i instead of 0
}
At the time of writing this answer, the number one google search for "convert string wstring" would land you on this page. My answer shows how to convert string to wstring, although this is NOT the actual question, and I should probably delete this answer but that is considered bad form. You may want to jump to this StackOverflow answer, which is now higher ranked than this page.
Here's a way to combining string, wstring and mixed string constants to wstring. Use the wstringstream class.
#include <sstream>
std::string narrow = "narrow";
std::wstring wide = "wide";
std::wstringstream cls;
cls << " abc " << narrow.c_str() << L" def " << wide.c_str();
std::wstring total= cls.str();
There are two options for creating and updating databases.
One is to create a database externally, then place it in the assets folder of the project and then copy the entire database from there. This is much quicker if the database has a lot of tables and other components. Upgrades are triggered by changing the database version number in the res/values/strings.xml file. Upgrades would then be accomplished by creating a new database externally, replacing the old database in the assets folder with the new database, saving the old database in internal storage under another name, copying the new database from the assets folder into internal storage, transferring all of the data from the old database (that was renamed earlier) into the new database and finally deleting the old database. You can create a database originally by using the SQLite Manager FireFox plugin to execute your creation sql statements.
The other option is to create a database internally from a sql file. This is not as quick but the delay would probably be unnoticeable to the users if the database has only a few tables. Upgrades are triggered by changing the database version number in the res/values/strings.xml file. Upgrades would then be accomplished by processing an upgrade sql file. The data in the database will remain unchanged except when its container is removed, for example dropping a table.
The example below demonstrates how to use either method.
Here is a sample create_database.sql file. It is to be placed in the assets folder of the project for the internal method or copied into the "Execute SQL' of SQLite Manager to create the database for the external method. (NOTE: Notice the comment about the table required by Android.)
--Android requires a table named 'android_metadata' with a 'locale' column
CREATE TABLE "android_metadata" ("locale" TEXT DEFAULT 'en_US');
INSERT INTO "android_metadata" VALUES ('en_US');
CREATE TABLE "kitchen_table";
CREATE TABLE "coffee_table";
CREATE TABLE "pool_table";
CREATE TABLE "dining_room_table";
CREATE TABLE "card_table";
Here is a sample update_database.sql file. It is to be placed in the assets folder of the project for the internal method or copied into the "Execute SQL' of SQLite Manager to create the database for the external method. (NOTE: Notice that all three types of SQL comments will be ignored by the sql parser that is included in this example.)
--CREATE TABLE "kitchen_table"; This is one type of comment in sql. It is ignored by parseSql.
/*
* CREATE TABLE "coffee_table"; This is a second type of comment in sql. It is ignored by parseSql.
*/
{
CREATE TABLE "pool_table"; This is a third type of comment in sql. It is ignored by parseSql.
}
/* CREATE TABLE "dining_room_table"; This is a second type of comment in sql. It is ignored by parseSql. */
{ CREATE TABLE "card_table"; This is a third type of comment in sql. It is ignored by parseSql. }
--DROP TABLE "picnic_table"; Uncomment this if picnic table was previously created and now is being replaced.
CREATE TABLE "picnic_table" ("plates" TEXT);
INSERT INTO "picnic_table" VALUES ('paper');
Here is an entry to add to the /res/values/strings.xml file for the database version number.
<item type="string" name="databaseVersion" format="integer">1</item>
Here is an activity that accesses the database and then uses it. (Note: You might want to run the database code in a separate thread if it uses a lot of resources.)
package android.example;
import android.app.Activity;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;

I personally favor HSQLDB, but mostly because it was the first I tried.
H2 is said to be faster and provides a nicer GUI frontend (which is generic and works with any JDBC driver, by the way).
At least HSQLDB, H2 and Derby provide server modes which is great for development, because you can access the DB with your application and some tool at the same time (which embedded mode usually doesn't allow).

Here's my EmguCV (a C# port of OpenCV) solution:
public static Image<TColor, TDepth> Rotate90<TColor, TDepth>(this Image<TColor, TDepth> img)
where TColor : struct, IColor
where TDepth : new()
{
var rot = new Image<TColor, TDepth>(img.Height, img.Width);
CvInvoke.cvTranspose(img.Ptr, rot.Ptr);
rot._Flip(FLIP.HORIZONTAL);
return rot;
}
public static Image<TColor, TDepth> Rotate180<TColor, TDepth>(this Image<TColor, TDepth> img)
where TColor : struct, IColor
where TDepth : new()
{
var rot = img.CopyBlank();
rot = img.Flip(FLIP.VERTICAL);
rot._Flip(FLIP.HORIZONTAL);
return rot;
}
public static void _Rotate180<TColor, TDepth>(this Image<TColor, TDepth> img)
where TColor : struct, IColor
where TDepth : new()
{
img._Flip(FLIP.VERTICAL);
img._Flip(FLIP.HORIZONTAL);
}
public static Image<TColor, TDepth> Rotate270<TColor, TDepth>(this Image<TColor, TDepth> img)
where TColor : struct, IColor
where TDepth : new()
{
var rot = new Image<TColor, TDepth>(img.Height, img.Width);
CvInvoke.cvTranspose(img.Ptr, rot.Ptr);
rot._Flip(FLIP.VERTICAL);
return rot;
}
Shouldn't be too hard to translate it back into C++.
For a simple approach using jQuery I've found this to work well:
// Wait for element to exist.
function elementLoaded(el, cb) {
if ($(el).length) {
// Element is now loaded.
cb($(el));
} else {
// Repeat every 500ms.
setTimeout(function() {
elementLoaded(el, cb)
}, 500);
}
};
elementLoaded('.element-selector', function(el) {
// Element is ready to use.
el.click(function() {
alert("You just clicked a dynamically inserted element");
});
});
Here we simply check every 500ms to see whether the element is loaded, when it is, we can use it.
This is especially useful for adding click handlers to elements which have been dynamically added to the document.
you can also do this
margin-top:-30px;
min-height:40px;
this "help" to stop the div yanking everything up a bit.
The saving of time in UTC format can help better as Kristen suggested.
Make sure that you are using 24 hr clock because there is no meridian AM or PM be used in UTC.
Example:
Its still preferrable to use standard four digit format.
Another similar solution:
>>> a=datetime.now()
>>> "%s:%s.%s" % (a.hour, a.minute, a.microsecond)
'14:28.971209'
Yes, I know I didn't get the string formatting perfect.
MainLabel:BEGIN
IF (<condition>) IS NOT NULL THEN
LEAVE MainLabel;
END IF;
....code
i.e.
IF (@skipMe) IS NOT NULL THEN /* @skipMe returns Null if never set or set to NULL */
LEAVE MainLabel;
END IF;
How and where is
app.run()
used? After module definition or afterapp.config()
, afterapp.controller()
?
In your package.js E.g. /packages/dashboard/public/controllers/dashboard.js
Make it look like this
var app = angular.module('mean.dashboard', ['ui.bootstrap']);
app.controller('DashboardController', ['$scope', 'Global', 'Dashboard',
function($scope, Global, Dashboard) {
$scope.global = Global;
$scope.package = {
name: 'dashboard'
};
// ...
}
]);
app.run(function(editableOptions) {
editableOptions.theme = 'bs3'; // bootstrap3 theme. Can be also 'bs2', 'default'
});
<script>
var url= "http://www.google.com";
window.location = url;
</script>
Open command prompt, go to the app folder, e.g. D:\angular-tour-of-heroes\src\app
Then create a new file using the following command:
ng generate class hero
This will create a hero.ts
file. Then you can paste the export code, and the error is gone.
Here is my quick and temporary way to run a Makefile
C:\Program Files (x86)\GnuWin32\bin
libiconv2.dll libintl3.dll make.exe
make.exe
done.
Plus, you can add arguments after the command, such as
make.exe skel
If you have a list of words you can do a method like this:
public bool ContainWords(List<string> wordList, string text)
{
foreach(string currentWord in wordList)
if(!text.Contains(currentWord))
return false;
return true;
}
The input in the markup is missing "type"
, the input (text I assume) has the attribute name="name"
and ID="cname"
, the provided code by Ayo calls the input named "cname"* where it should be "name".
Be sure to check Xcode Preferences -> Locations.
The Command Line Tools I had selected was for the previous version of Xcode (8.2.1 instead of 10.1)
For restarting the animation of a gif image, you can use the code:
$('#img_gif').attr('src','file.gif?' + Math.random());
Okay, from your question, you just simply want to read a particular column. So, while iterating over a row and then on its cells, your can simply check the index of the column.
Iterator<Row> rowIterator = mySheet.iterator(); // Traversing over each row of XLSX file
while (rowIterator.hasNext()) {
Row row = rowIterator.next(); // For each row, iterate through each columns
Iterator<Cell> cellIterator = row.cellIterator();
while (cellIterator.hasNext()) {
Cell cell = cellIterator.next();
println "column index"+cell.getColumnIndex()//You will have your columns fixed in Excel file
if(cell.getColumnIndex()==3)//for example of c
{
print "done"
}
}
}
I am using POI 3.12-- 'org.apache.poi:poi:3.12' Hope it helps. Cheers!
You can do this via native javascript code like so:
var pattern = /a href=/g;
var sanitizedMarkDownText = rawMarkDownText.replace(pattern,"a target='_blank' href=");
If you don't mind logging the message also to syslog, the not_so_ugly way is:
logger -s $msg
The -s option means: "Output the message to standard error as well as to the system log."
With Guava you can do:
Optional.fromNullable(a).or(b);
which doesn't throw NPE if both a
and b
are null
.
EDIT: I was wrong, it does throw NPE. The correct way as commented by Michal Cizmazia is:
Optional.fromNullable(a).or(Optional.fromNullable(b)).orNull();
If you just put '/' in the href it will reload the current window.
<a href="/">
Reload the page
</a>

A no throw specification on an inlined function that only returns a member variable and could not possibly throw exceptions may be used by some compilers to do pessimizations (a made-up word for the opposite of optimizations) that can have a detrimental effect on performance. This is described in the Boost literature: Exception-specification
With some compilers a no-throw specification on non-inline functions may be beneficial if the correct optimizations are made and the use of that function impacts performance in a way that it justifies it.
To me it sounds like whether to use it or not is a call made by a very critical eye as part of a performance optimization effort, perhaps using profiling tools.
A quote from the above link for those in a hurry (contains an example of bad unintended effects of specifying throw on an inline function from a naive compiler):
Exception-specification rationale
Exception specifications [ISO 15.4] are sometimes coded to indicate what exceptions may be thrown, or because the programmer hopes they will improve performance. But consider the following member from a smart pointer:
T& operator*() const throw() { return *ptr; }
This function calls no other functions; it only manipulates fundamental data types like pointers Therefore, no runtime behavior of the exception-specification can ever be invoked. The function is completely exposed to the compiler; indeed it is declared inline Therefore, a smart compiler can easily deduce that the functions are incapable of throwing exceptions, and make the same optimizations it would have made based on the empty exception-specification. A "dumb" compiler, however, may make all kinds of pessimizations.
For example, some compilers turn off inlining if there is an exception-specification. Some compilers add try/catch blocks. Such pessimizations can be a performance disaster which makes the code unusable in practical applications.
Although initially appealing, an exception-specification tends to have consequences that require very careful thought to understand. The biggest problem with exception-specifications is that programmers use them as though they have the effect the programmer would like, instead of the effect they actually have.
A non-inline function is the one place a "throws nothing" exception-specification may have some benefit with some compilers.
When this happened to me (out of nowhere) I was about to dive into the top answer above, and then I figured I'd close the project, close Visual Studio, and then re-open everything. Problem solved. VS bug?
The two syntaxes are not equivalent and it can lead to unexpected errors. Here is a simple example showing the differences. If you have a model:
from django.db import models
class Test(models.Model):
added = models.DateTimeField(auto_now_add=True)
And you create a first object:
foo = Test.objects.create(pk=1)
Then you try to create an object with the same primary key:
foo_duplicate = Test.objects.create(pk=1)
# returns the error:
# django.db.utils.IntegrityError: (1062, "Duplicate entry '1' for key 'PRIMARY'")
foo_duplicate = Test(pk=1).save()
# returns the error:
# django.db.utils.IntegrityError: (1048, "Column 'added' cannot be null")
There are lots of operations in NumPy that could perhaps be put together to accomplish this. This will return indices of elements equal to item:
numpy.nonzero(array - item)
You could then take the first elements of the lists to get a single element.
Zip your file (.zip) and IE will give the user the option to open or download the file.
It is possible with a one liner:
values = ('275', '54000', '0.0', '5000.0', '0.0')
values = ('300', *values[1:])
Since Java 7 there is factory method Locale.forLanguageTag
and instance method Locale.toLanguageTag
using IETF language tags.
The suitable way to analyze an algorithm is by determining its worst case scenarios.
Euclidean GCD's worst case occurs when Fibonacci Pairs are involved.
void EGCD(fib[i], fib[i - 1])
, where i > 0.
For instance, let's opt for the case where the dividend is 55, and the divisor is 34 (recall that we are still dealing with fibonacci numbers).
As you may notice, this operation costed 8 iterations (or recursive calls).
Let's try larger Fibonacci numbers, namely 121393 and 75025. We can notice here as well that it took 24 iterations (or recursive calls).
You can also notice that each iterations yields a Fibonacci number. That's why we have so many operations. We can't obtain similar results only with Fibonacci numbers indeed.
Hence, the time complexity is going to be represented by small Oh (upper bound), this time. The lower bound is intuitively Omega(1): case of 500 divided by 2, for instance.
Let's solve the recurrence relation:
We may say then that Euclidean GCD can make log(xy) operation at most.
You can refer this one too, I have written step by step procedure of Manual Crash Re-Symbolication.
STEP 1
Move all the above files (MyApp.app, MyApp-dSYM.dSYM and MyApp-Crash-log.crash) into a Folder with a convenient name wherever you can go using Terminal easily.
For me, Desktop is the most easily reachable place ;) So, I have moved these three files into a folder MyApp at Desktop.
STEP 2
Now its turn of Finder, Go to the path from following whichever is applicable for your XCODE version.
Use this command to find the symbolicatecrash
script file,
find /Applications/Xcode.app -name symbolicatecrash
Xcode 8, Xcode 9, Xcode 11 /Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash
Xcode 7.3
/Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash
XCode 7 /Applications/Xcode.app/Contents/SharedFrameworks/DTDeviceKitBase.framework/Versions/A/Resources/symbolicatecrash
Xcode 6 /Applications/Xcode.app/Contents/SharedFrameworks/DTDeviceKitBase.framework/Versions/A/Resources
Lower then Xcode 6
Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKitBase.framework/Versions/A/Resources
Or
Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKit.framework/Versions/A/Resources
STEP 3
Add the found symbolicatecrash script file's directory to $PATH
env variable like this: sudo vim /etc/paths.d/Xcode-symbolicatecrash
and paste the script file's directory and save the file. When opening a new terminal, you can call symbolicatecrash
at any folder as commands located in /usr/bin
.
Or
Copy symbolicatecrash file from this location, and paste it to the Desktop/MyApp (Wait… Don’t blindly follow me, I am pasting sybolicatecrash file in folder MyApp, one that you created in step one at your favorite location, having three files.)
STEP 4
Open Terminal, and CD to the MyApp Folder.
cd Desktop/MyApp — Press Enter
export DEVELOPER_DIR=$(xcode-select --print-path)
— Press Enter
./symbolicatecrash -v MyApp-Crash-log.crash MyApp.dSYM
— Press Enter
That’s it !! Symbolicated logs are on your terminal… now what are you waiting for? Now simply, Find out the Error and resolve it ;)
Happy Coding !!!
If you decide to use Underscore.js you better do
var foo = { 'alpha' : 'puffin', 'beta' : 'beagle' };
var keys = [];
_.each( foo, function( val, key ) {
keys.push(key);
});
console.log(keys);
{}
defines the contents of the array, in this case it is empty. These would both have an array of three String
s
String[] array = {"element1","element2","element3"};
String[] array = new String[] {"element1","element2","element3"};
while []
on the expression side (right side of =
) of a statement defines the size of an intended array, e.g. this would have an array of 10 locations to place String
s
String[] array = new String[10];
...But...
String array = new String[10]{}; //The line you mentioned above
Was wrong because you are defining an array of length 10 ([10]
), then defining an array of length 0 ({}
), and trying to set them to the same array reference (array
) in one statement. Both cannot be set.
Additionally
The array should be defined as an array of a given type at the start of the statement like String[] array
. String array = /* array value*/
is saying, set an array value to a String
, not to an array of String
s.
var t = document.getElementById("table"),
d = t.getElementsByTagName("tr"),
r = d.getElementsByTagName("td");
needs to be:
var t = document.getElementById("table"),
tableRows = t.getElementsByTagName("tr"),
r = [], i, len, tds, j, jlen;
for ( i =0, len = tableRows.length; i<len; i++) {
tds = tableRows[i].getElementsByTagName('td');
for( j = 0, jlen = tds.length; j < jlen; j++) {
r.push(tds[j]);
}
}
Because getElementsByTagName
returns a NodeList
an Array-like structure. So you need to loop through the return nodes and then populate you r
like above.
((KidsStoryDashboard)getActivity()).values(title_txt,bannerImgUrl);
public void values(String title_txts, String bannerImgUrl) {
if (!title_txts.isEmpty()) {
//Do something to set text
}
imageLoader.displayImage(bannerImgUrl, htab_header_image, doption);
}
Although there is nothing wrong with the other solutions presented, you could simplify and greatly escalate your solutions by using python's excellent library pandas.
Pandas is a library for handling data in Python, preferred by many Data Scientists.
Pandas has a simplified CSV interface to read and parse files, that can be used to return a list of dictionaries, each containing a single line of the file. The keys will be the column names, and the values will be the ones in each cell.
In your case:
import pandas
def create_dictionary(filename):
my_data = pandas.DataFrame.from_csv(filename, sep='\t', index_col=False)
# Here you can delete the dataframe columns you don't want!
del my_data['B']
del my_data['D']
# ...
# Now you transform the DataFrame to a list of dictionaries
list_of_dicts = [item for item in my_data.T.to_dict().values()]
return list_of_dicts
# Usage:
x = create_dictionary("myfile.csv")
This issue can be resolved by trying multiple solutions like:
I have just successfully downgraded from PHP5.3 on Ubuntu 10.
To do this I used the following script:
#! /bin/sh
php_packages=`dpkg -l | grep php | awk '{print $2}'`
sudo apt-get remove $php_packages
sed s/lucid/karmic/g /etc/apt/sources.list | sudo tee /etc/apt/sources.list.d/karmic.list
sudo mkdir -p /etc/apt/preferences.d/
for package in $php_packages;
do echo "Package: $package
Pin: release a=karmic
Pin-Priority: 991
" | sudo tee -a /etc/apt/preferences.d/php
done
sudo apt-get update
sudo apt-get install $php_packages
For anyone that doesn't know how to run scripts from the command line, here is a brief tutorial:
1. cd ~/
2. mkdir bin
3. sudo nano ~/bin/myscriptname.sh
4. paste in the script code I have posted above this
5. ctrl+x (this exits and prompts for you to save)
6. chmod u+x myscriptname.sh
These 6 steps create a script in a folder called "bin" in your home directory. You can then run this script by calling the following command:
~/bin/myscriptname.sh
Oulia!
Hope this helps some of you!
For reference, here is where I got the script: PHP5.2.10 for Ubuntu 10
There are several people on there all confirming that this works, and it worked a treat for me.
As I didn't want to break anything, I did this to be able to use newer versions of Python3 than Python v3.4 :
$ sudo update-alternatives --install /usr/local/bin/python3 python3 /usr/bin/python3.6 1
update-alternatives: using /usr/bin/python3.6 to provide /usr/local/bin/python3 (python3) in auto mode
$ sudo update-alternatives --install /usr/local/bin/python3 python3 /usr/bin/python3.7 2
update-alternatives: using /usr/bin/python3.7 to provide /usr/local/bin/python3 (python3) in auto mode
$ update-alternatives --list python3
/usr/bin/python3.6
/usr/bin/python3.7
$ sudo update-alternatives --config python3
There are 2 choices for the alternative python3 (providing /usr/local/bin/python3).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/bin/python3.7 2 auto mode
1 /usr/bin/python3.6 1 manual mode
2 /usr/bin/python3.7 2 manual mode
Press enter to keep the current choice[*], or type selection number: 1
update-alternatives: using /usr/bin/python3.6 to provide /usr/local/bin/python3 (python3) in manual mode
$ ls -l /usr/local/bin/python3 /etc/alternatives/python3
lrwxrwxrwx 1 root root 18 2019-05-03 02:59:03 /etc/alternatives/python3 -> /usr/bin/python3.6*
lrwxrwxrwx 1 root root 25 2019-05-03 02:58:53 /usr/local/bin/python3 -> /etc/alternatives/python3*
You can even write this:
private string foo = "foo";
private string bar
{
get => $"{foo}bar";
set
{
foo = value;
}
}
Generally speaking, you can update your index mapping using the put mapping api (reference here) :
curl -XPUT 'http://localhost:9200/advert_index/_mapping/advert_type' -d '
{
"advert_type" : {
"properties" : {
//your new mapping properties
}
}
}
'
It's especially useful for adding new fields. However, in your case, you will try to change the location type, which will cause a conflict and prevent the new mapping from being used.
You could use the put mapping api to add another property containing the location as a lat/lon array, but you won't be able to update the previous location field itself.
Finally, you will have to reindex your data for your new mapping to be taken into account.
The best solution would really be to create a new index.
If your problem with creating another index is downtime, you should take a look at aliases to make things go smoothly.
It has method to find all values from map:
Map<K, V> map=getMapObjectFromXyz();
Collection<V> vs= map.values();
Iterate over vs
to do some operation
Its a bit late to anwser, but I hope my answer been useful for someone, who needs to select Composite foreign keys.

You never refer to a specific style sheet. All CSS rules in a document are internally fused into one.
In the case of rules in both style sheets that apply to the same element with the same specificity, the style sheet embedded later will override the earlier one.
You can use an element inspector like Firebug to see which rules apply, and which ones are overridden by others.
I don't think what your asking is possible.
Basically, adding a class is the only way to accomplish this that I am aware of.
Try to use this free way to this, https://freenetexcel.codeplex.com
Workbook workbook = new Workbook();

In DB2, using single quotes instead of your double quotes will work. So that could translate the same in Oracle..

Doing this yourself is an awful idea. Use Json.NET. It has already solved the problem better than most programmers could if they were given months on end to work on it. As for your specific needs, parsing into arrays and such, check the documentation, particularly on JsonTextReader
. Basically, Json.NET handles JSON arrays natively and will parse them into strings, ints, or whatever the type happens to be without prompting from you. Here is a direct link to the basic code usages for both the reader and the writer, so you can have that open in a spare window while you're learning to work with this.
This is for the best: Be lazy this time and use a library so you solve this common problem forever.
Please remove e.preventDefault()
, because event.cancelable
of touchmove is false
.
So you can't call this method.
Looks like your buttons are not declared correctly (according to the latest jQuery UI documentation anyway).
try the following:
$( ".selector" ).dialog({
buttons: [{
text: "Ok",
click: function() {
$( this ).dialog( "close" );
}
}]
});

The answer with for
is correct, but if you really want to use functional style avoiding for
statement - you can use the following instead of your expression:
Array.from(Array(1000000), () => Math.random());
The Array.from() method creates a new Array instance from an array-like or iterable object. The second argument of this method is a map function to call on every element of the array.
Following the same idea you can rewrite it using ES2015 Spread operator:
[...Array(1000000)].map(() => Math.random())
In both examples you can get an index of the iteration if you need, for example:
[...Array(1000000)].map((_, i) => i + Math.random())
I have change all columns width in my case as
worksheet.Columns[1].ColumnWidth = 7;
worksheet.Columns[2].ColumnWidth = 15;
worksheet.Columns[3].ColumnWidth = 15;
worksheet.Columns[4].ColumnWidth = 15;
worksheet.Columns[5].ColumnWidth = 18;
worksheet.Columns[6].ColumnWidth = 8;
worksheet.Columns[7].ColumnWidth = 13;
worksheet.Columns[8].ColumnWidth = 17;
worksheet.Columns[9].ColumnWidth = 17;
Note: Columns in worksheet start with 1 not from 0 as in Arrary.

numpy.linspace()
gives you a one-dimensional NumPy array. For example:
>>> my_array = numpy.linspace(1, 10, 10)
>>> my_array
array([ 1., 2., 3., 4., 5., 6., 7., 8., 9., 10.])
Therefore:
for index,point in my_array
cannot work. You would need some kind of two-dimensional array with two elements in the second dimension:
>>> two_d = numpy.array([[1, 2], [4, 5]])
>>> two_d
array([[1, 2], [4, 5]])
Now you can do this:
>>> for x, y in two_d:
print(x, y)
1 2
4 5
use the new line character of a javascript instead of '\n'.. eg: "Hello\nWorld" use "Hello\x0AWorld" It works great!!
I know this isn't a 'replacement' WebBrowser control, but I was having some awful rendering issues whilst showing a page that was using BootStrap 3+ for layout etc, and then I found a post that suggested I use the following. Apparently, it's specific to IE and tells it to use the latest variation found on the client machine for rendering (so it won't use IE7, which I believe is the default).
So just put:
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
somewhere in the head part of your document.
Obviously, if it's not your document, this won't help - though I personally consider it to be a security hole if you're reading pages not created by yourself through the WebBrowser control - why not just use a web browser!
Postgresql historically doesn't support procedural code at the command level - only within functions. However, in Postgresql 9, support has been added to execute an inline code block that effectively supports something like this, although the syntax is perhaps a bit odd, and there are many restrictions compared to what you can do with SQL Server. Notably, the inline code block can't return a result set, so can't be used for what you outline above.
In general, if you want to write some procedural code and have it return a result, you need to put it inside a function. For example:
CREATE OR REPLACE FUNCTION somefuncname() RETURNS int LANGUAGE plpgsql AS $$
DECLARE
one int;
two int;
BEGIN
one := 1;
two := 2;
RETURN one + two;
END
$$;
SELECT somefuncname();
The PostgreSQL wire protocol doesn't, as far as I know, allow for things like a command returning multiple result sets. So you can't simply map T-SQL batches or stored procedures to PostgreSQL functions.
SearchView
can be added as actionView
in menu using
app:useActionClass = "android.support.v7.widget.SearchView" .
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="rohksin.com.searchviewdemo.MainActivity">
<item
android:id="@+id/searchBar"
app:showAsAction="always"
app:actionViewClass="android.support.v7.widget.SearchView"
/>
</menu>
SearchView.OnQueryTextListener
has two abstract methods. So your activity skeleton would now look like this after implementing SearchView text listener.
YourActivity extends AppCompatActivity implements SearchView.OnQueryTextListener{
public boolean onQueryTextSubmit(String query)
public boolean onQueryTextChange(String newText)
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
MenuItem searchItem = menu.findItem(R.id.searchBar);
SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setQueryHint("Search People");
searchView.setOnQueryTextListener(this);
searchView.setIconified(false);
return true;
}
This is how you can implement abstract methods of the listener.
@Override
public boolean onQueryTextSubmit(String query) {
// This method can be used when a query is submitted eg. creating search history using SQLite DB
Toast.makeText(this, "Query Inserted", Toast.LENGTH_SHORT).show();
return true;
}
@Override
public boolean onQueryTextChange(String newText) {
adapter.filter(newText);
return true;
}
You can come up with your own logic based on your requirement. Here is the sample code snippet to show the list of Name which contains the text typed in the SearchView
.
public void filter(String queryText)
{
list.clear();
if(queryText.isEmpty())
{
list.addAll(copyList);
}
else
{
for(String name: copyList)
{
if(name.toLowerCase().contains(queryText.toLowerCase()))
{
list.add(name);
}
}
}
notifyDataSetChanged();
}
Full working code sample can be found > HERE

The solution by @virgo47 is very fast, but approximate. The accepted answer uses Normalizer and a regular expression. I wondered what part of the time was taken by Normalizer versus the regular expression, since removing all the non-ASCII characters can be done without a regex:
import java.text.Normalizer;
public class Strip {
public static String flattenToAscii(String string) {
StringBuilder sb = new StringBuilder(string.length());
string = Normalizer.normalize(string, Normalizer.Form.NFD);
for (char c : string.toCharArray()) {
if (c <= '\u007F') sb.append(c);
}
return sb.toString();
}
}
Small additional speed-ups can be obtained by writing into a char[] and not calling toCharArray(), although I'm not sure that the decrease in code clarity merits it:
public static String flattenToAscii(String string) {
char[] out = new char[string.length()];
string = Normalizer.normalize(string, Normalizer.Form.NFD);
int j = 0;
for (int i = 0, n = string.length(); i < n; ++i) {
char c = string.charAt(i);
if (c <= '\u007F') out[j++] = c;
}
return new String(out);
}
This variation has the advantage of the correctness of the one using Normalizer and some of the speed of the one using a table. On my machine, this one is about 4x faster than the accepted answer, and 6.6x to 7x slower that @virgo47's (the accepted answer is about 26x slower than @virgo47's on my machine).
It wont break if you wrap each item in a div. Check out my fiddle with the link below. I made the width of the fieldset 125px and made each item 50px wide. You'll see the label and checkbox remain side by side on a new line and don't break.
<fieldset>
<div class="item">
<input type="checkbox" id="a">
<label for="a">a</label>
</div>
<div class="item">
<input type="checkbox" id="b">
<!-- depending on width, a linebreak can occur here. -->
<label for="b">bgf bh fhg fdg hg dg gfh dfgh</label>
</div>
<div class="item">
<input type="checkbox" id="c">
<label for="c">c</label>
</div>
</fieldset>
you can set Focus
to a specific Cell
by setting Selected
property to true
dataGridView1.Rows[rowindex].Cells[columnindex].Selected = true;
to avoid Multiple Selection just set
dataGridView1.MultiSelect = false;
pip3 freeze --local | xargs pip3 uninstall -y
The case might be that one has to run this command several times to get an empty pip3 freeze --local

When using jQuery you do not need to call a stop function separate.
You can just return false
in the event handler
This will stop the event and cancel bubbling..
Also see event.preventDefault() vs. return false
From the jQuery docs:
These handlers, therefore, may prevent the delegated handler from triggering by calling
event.stopPropagation()
or returningfalse
.
The accepted answer doesn't handle the from X import Y case. This code handles it and the standard import case as well:
def importOrReload(module_name, *names):
import sys
if module_name in sys.modules:
reload(sys.modules[module_name])
else:
__import__(module_name, fromlist=names)
for name in names:
globals()[name] = getattr(sys.modules[module_name], name)
# use instead of: from dfly_parser import parseMessages
importOrReload("dfly_parser", "parseMessages")
In the reloading case, we reassign the top level names to the values stored in the newly reloaded module, which updates them.
The reason you're seeing that error is because document.getElementsByName
returns a NodeList
of elements. And a NodeList
of elements does not have a .value
property.
Use this instead:
document.getElementsByName("acc")[0].value
You can load the images at the beginning and change the css attributes to show every image.
var images = array();
for( url in your_urls_array ){
var img = document.createElement( "img" );
//here the image attributes ( width, height, position, etc )
images.push( img );
}
function player( position )
{
images[position-1].style.display = "none" //be careful working with the first position
images[position].style.display = "block";
//reset position if needed
timer = setTimeOut( "player( position )", time );
}
In Node "Buffer
instances are also Uint8Array
instances", so buf.toString()
works in this case.
Here is what you want to put in the project's Post-build event command line:
copy /Y "$(TargetDir)$(ProjectName).dll" "$(SolutionDir)lib\$(ProjectName).dll"
EDIT: Or if your target name is different than the Project Name.
copy /Y "$(TargetDir)$(TargetName).dll" "$(SolutionDir)lib\$(TargetName).dll"
CMP
subtracts the operands and sets the flags. Namely, it sets the zero flag if the difference is zero (operands are equal).
TEST
sets the zero flag, ZF
, when the result of the AND operation is zero. If two operands are equal, their bitwise AND is zero when both are zero. TEST
also sets the sign flag, SF
, when the most significant bit is set in the result, and the parity flag, PF
, when the number of set bits is even.
JE
[Jump if Equals] tests the zero flag and jumps if the flag is set. JE
is an alias of JZ
[Jump if Zero] so the disassembler cannot select one based on the opcode. JE
is named such because the zero flag is set if the arguments to CMP
are equal.
So,
TEST %eax, %eax
JE 400e77 <phase_1+0x23>
jumps if the %eax
is zero.
On Xampp, in php.ini you must check mysql.connect_timeout either. So, for example, change it to:
mysql.connect_timeout = 3600
That time will be always counted in seconds (so 1 hour in my example)
Please try this one and I guarantee that it will work
<script type="text/javascript">
function blink() {
var blinks = document.getElementsByTagName('blink');
for (var i = blinks.length - 1; i >= 0; i--) {
var s = blinks[i];
s.style.visibility = (s.style.visibility === 'visible') ? 'hidden' : 'visible';
}
window.setTimeout(blink, 1000);
}
if (document.addEventListener) document.addEventListener("DOMContentLoaded", blink, false);
else if (window.addEventListener) window.addEventListener("load", blink, false);
else if (window.attachEvent) window.attachEvent("onload", blink);
else window.onload = blink;
Then put this below:
<blink><center> Your text here </blink></div>
I just found another reason why to get this error. I cleaned my GAC from all versions of a specific library and built my project with reference to specific version deployed together with the executable. When I run the project I got this exception searching for a newer version of the library.
The reason was publisher policy. When I uninstalled library's versions from GAC I forgot to uninstall publisher policy assemblies as well so instead of using my locally deployed assembly the assembly loader found publisher policy in GAC which told it to search for a newer version.
response[0]
is not defined, check if it is defined and then check for its property title.
if(typeof response[0] !== 'undefined' && typeof response[0].title !== 'undefined'){

You should have started the mongod instance with access control, i.e., the --auth command line option, such as:
$ mongod --auth
Let's start the mongo shell, and create an administrator in the admin database:
$ mongo
> use admin
> db.createUser(
{
user: "myUserAdmin",
pwd: "abc123",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
}
)
Now if you run command "db.stats()", or "show users", you will get error "not authorized on admin to execute command..."
> db.stats()
{
"ok" : 0,
"errmsg" : "not authorized on admin to execute command { dbstats: 1.0, scale: undefined }",
"code" : 13,
"codeName" : "Unauthorized"
}
The reason is that you still have not granted role "read" or "readWrite" to user myUserAdmin. You can do it as below:
> db.auth("myUserAdmin", "abc123")
> db.grantRolesToUser("myUserAdmin", [ { role: "read", db: "admin" } ])
Now You can verify it (Command "show users" now works):
> show users
{
"_id" : "admin.myUserAdmin",
"user" : "myUserAdmin",
"db" : "admin",
"roles" : [
{
"role" : "read",
"db" : "admin"
},
{
"role" : "userAdminAnyDatabase",
"db" : "admin"
}
]
}
Now if you run "db.stats()", you'll also be OK:
> db.stats()
{
"db" : "admin",
"collections" : 2,
"views" : 0,
"objects" : 3,
"avgObjSize" : 151,
"dataSize" : 453,
"storageSize" : 65536,
"numExtents" : 0,
"indexes" : 3,
"indexSize" : 81920,
"ok" : 1
}
This user and role mechanism can be applied to any other databases in MongoDB as well, in addition to the admin database.
(MongoDB version 3.4.3)
With vim from command line:

Lambda expressions are a simpler syntax for anonymous delegates and can be used everywhere an anonymous delegate can be used. However, the opposite is not true; lambda expressions can be converted to expression trees which allows for a lot of the magic like LINQ to SQL.
The following is an example of a LINQ to Objects expression using anonymous delegates then lambda expressions to show how much easier on the eye they are:
// anonymous delegate
var evens = Enumerable
.Range(1, 100)
.Where(delegate(int x) { return (x % 2) == 0; })
.ToList();
// lambda expression
var evens = Enumerable
.Range(1, 100)
.Where(x => (x % 2) == 0)
.ToList();
Lambda expressions and anonymous delegates have an advantage over writing a separate function: they implement closures which can allow you to pass local state to the function without adding parameters to the function or creating one-time-use objects.
Expression trees are a very powerful new feature of C# 3.0 that allow an API to look at the structure of an expression instead of just getting a reference to a method that can be executed. An API just has to make a delegate parameter into an Expression<T>
parameter and the compiler will generate an expression tree from a lambda instead of an anonymous delegate:
void Example(Predicate<int> aDelegate);
called like:
Example(x => x > 5);
becomes:
void Example(Expression<Predicate<int>> expressionTree);
The latter will get passed a representation of the abstract syntax tree that describes the expression x > 5
. LINQ to SQL relies on this behavior to be able to turn C# expressions in to the SQL expressions desired for filtering / ordering / etc. on the server side.
You may also want to cut the data frame into an arbitrary number of smaller dataframes. Here, we cut into two dataframes.
x = data.frame(num = 1:26, let = letters, LET = LETTERS)
set.seed(10)
split(x, sample(rep(1:2, 13)))
gives
$`1`
num let LET
3 3 c C
6 6 f F
10 10 j J
12 12 l L
14 14 n N
15 15 o O
17 17 q Q
18 18 r R
20 20 t T
21 21 u U
22 22 v V
23 23 w W
26 26 z Z
$`2`
num let LET
1 1 a A
2 2 b B
4 4 d D
5 5 e E
7 7 g G
8 8 h H

19 19 s S
24 24 x X
25 25 y Y
You can also split a data frame based upon an existing column. For example, to create three data frames based on the cyl
column in mtcars
:
split(mtcars,mtcars$cyl)
Just run graphics.off()

i use (and recommend):
$(document).attr("title", "Another Title");
and it works in IE as well this is an alias to
document.title = "Another Title";
Some will debate on wich is better, prop or attr, and since prop call DOM properties and attr Call HTML properties, i think this is actually better...
use this after the DOM Load
$(function(){
$(document).attr("title", "Another Title");
});
hope this helps.
Update for mid 2016:
The things are changing so fast that if it's late 2017 this answer might not be up to date anymore!
Beginners can quickly get lost in choice of build tools and workflows, but what's most up to date in 2016 is not using Bower, Grunt or Gulp at all! With help of Webpack you can do everything directly in NPM!
Google "npm as build tool" result: https://medium.com/@dabit3/introduction-to-using-npm-as-a-build-tool-b41076f488b0#.c33e74tsa
Don't get me wrong people use other workflows and I still use GULP in my legacy project(but slowly moving out of it), but this is how it's done in the best companies and developers working in this workflow make a LOT of money!
Look at this template it's a very up-to-date setup consisting of a mixture of the best and the latest technologies: https://github.com/coryhouse/react-slingshot
Your questions:
When I want to add a package (and check in the dependency into git), where does it belong - into package.json or into bower.json
Everything belongs in package.json now
Dependencies required for build are in "devDependencies" i.e. npm install require-dir --save-dev
(--save-dev updates your package.json by adding an entry to devDependencies)
npm install lodash --save
(--save updates your package.json by adding an entry to dependencies)If that is the case, when should I ever install packages explicitly like that without adding them to the file that manages dependencies (apart from installing command line tools globally)?
Always. Just because of comfort. When you add a flag (--save-dev
or --save
) the file that manages deps (package.json) gets updated automatically. Don't waste time by editing dependencies in it manually. Shortcut for npm install --save-dev package-name
is npm i -D package-name
and shortcut for npm install --save package-name
is npm i -S package-name
To minimally modify your example, you could amend the code to:
class myclass(object):
def __init__(self): # this method creates the class object.
pass
def average(self,a,b,c): #get the average of three numbers
result=a+b+c
result=result/3
return result
mystuff=myclass() # by default the __init__ method is then called.
print mystuff.average(a,b,c)
Or to expand it more fully, allowing you to add other methods.
class myclass(object):
def __init__(self,a,b,c):
self.a=a
self.b=b
self.c=c
def average(self): #get the average of three numbers
result=self.a+self.b+self.c
result=result/3
return result
a=9
b=18
c=27
mystuff=myclass(a, b, c)
print mystuff.average()
Authentication is done via a simple ldap_bind command that takes the users DN and the password. The user is authenticated when the bind is successfull. Usually you would get the users DN via an ldap_search based on the users uid or email-address.
Getting the users roles is something different as it is an ldap_search and depends on where and how the roles are stored in the ldap. But you might be able to retrieve the roles during the lap_search used to find the users DN.
The :empty
pseudo-selector is used to see if an element contains no childs, you should check the value :
$('#apply-form input').blur(function() {
if(!this.value) { // zero-length string
$(this).parents('p').addClass('warning');
}
});
You can try element[0].scrollTop, in my opinion this solution is faster.
Here you have bigger example - http://cvmlrobotics.blogspot.de/2013/03/angularjs-get-element-offset-position.html
Do this
Build -> Rebuild Project
You could also do
function insertAfter(node1, node2) {
node1.outerHTML += node2.outerHTML;
}
or
function insertAfter2(node1, node2) {
var wrap = document.createElement("div");
wrap.appendChild(node2.cloneNode(true));
var node2Html = wrap.innerHTML;
node1.insertAdjacentHTML('afterend', node2Html);
}
