I had the same issue where I would want to show / hide Views, but I really didn't want the UI jumping around when things were added/removed or necessarily to deal with re-rendering.

I wrote a simple Component to deal with it for me. Animated by default, but easy to toggle. I put it on GitHub and NPM with a readme, but all the code is below.

npm install --save react-native-hideable-view

import React, { Component, PropTypes } from 'react';
import { Animated  } from 'react-native';

class HideableView extends Component {
  constructor(props) {
    super(props);
    this.state = {
      opacity: new Animated.Value(this.props.visible ? 1 : 0)
    }
  }

  animate(show) {
    const duration = this.props.duration ? parseInt(this.props.duration) : 500;
    Animated.timing(
      this.state.opacity, {
        toValue: show ? 1 : 0,
        duration: !this.props.noAnimation ? duration : 0
      }
    ).start();
  }

  shouldComponentUpdate(nextProps) {
    return this.props.visible !== nextProps.visible;
  }

  componentWillUpdate(nextProps, nextState) {
    if (this.props.visible !== nextProps.visible) {
      this.animate(nextProps.visible);
    }
  }

  render() {
    if (this.props.removeWhenHidden) {
      return (this.visible && this.props.children);
    }
    return (
      <Animated.View style={{opacity: this.state.opacity}}>
        {this.props.children}
      </Animated.View>
    )
  }
}

HideableView.propTypes = {
  visible: PropTypes.bool.isRequired,
  duration: PropTypes.number,
  removeWhenHidden: PropTypes.bool,
  noAnimation: PropTypes.bool
}

export default HideableView;

Sounds like you got your answer. Passing by value is expensive, but gives you a copy to work with if you need it.

This word, hence, VanillaJS is a just damn joke that changed my life. I had gone to a German company for an interview, I was very poor in JavaScript and CSS, very poor, so the Interviewer said to me: We're working here with VanillaJs, So you should know this framework.

Definitely, I understood that I'was rejected, but for one week I seek for VanillaJS, After all, I found THIS LINK.

What I am just was because of that joke.

VanillaJS === plain `JavaScript`

In case anyone wants to have a responsive flexbox with percentages (%) it is much easier for media queries.

flex-basis: 25%;

This will be a lot smoother when testing.

String x = "stackoverflow";
String [] y = x.split("");

Sort the unsorted hashmap in ascending order.

// Sorting the list based on values
Collections.sort(list, new Comparator<Entry<String, Integer>>() {
public int compare(Entry<String, Integer> o1, Entry<String, Integer> o2) 
{
                return o2.getValue().compareTo(o1.getValue());
        }
    });

    // Maintaining insertion order with the help of LinkedList
    Map<String, Integer> sortedMap = new LinkedHashMap<String, Integer>();
    for (Entry<String, Integer> entry : list) {
        sortedMap.put(entry.getKey(), entry.getValue());
    }

For the OP's command:

select compid,2, convert(datetime, '01/01/' + CONVERT(char(4),cal_yr) ,101) ,0,  Update_dt, th1, th2, th3_pc , Update_id, Update_dt,1
from  #tmp_CTF** 

I get this error:

Msg 102, Level 15, State 1, Line 2
Incorrect syntax near '*'.

when debugging something like this split the long line up so you'll get a better row number:

select compid
,2
, convert(datetime
, '01/01/' 
+ CONVERT(char(4)
,cal_yr) 
,101) 
,0
,  Update_dt
, th1
, th2
, th3_pc 
, Update_id
, Update_dt
,1
from  #tmp_CTF** 

this now results in:

Msg 102, Level 15, State 1, Line 16
Incorrect syntax near '*'.

which is probably just from the OP not putting the entire command in the question, or use [ ] braces to signify the table name:

from [#tmp_CTF**]

if that is the table name.

You can try with SqlBulkCopy class.

Lets you efficiently bulk load a SQL Server table with data from another source.

There is a cool blog post about how you can use it.

Streams

If you are using Java 8, perhaps you could try something like this:

public boolean containsName(final List<MyObject> list, final String name){
    return list.stream().filter(o -> o.getName().equals(name)).findFirst().isPresent();
}

Or alternatively, you could try something like this:

public boolean containsName(final List<MyObject> list, final String name){
    return list.stream().map(MyObject::getName).filter(name::equals).findFirst().isPresent();
}

This method will return true if the List<MyObject> contains a MyObject with the name name. If you want to perform an operation on each of the MyObjects that getName().equals(name), then you could try something like this:

public void perform(final List<MyObject> list, final String name){
    list.stream().filter(o -> o.getName().equals(name)).forEach(
            o -> {
                //...
            }
    );
}

Where o represents a MyObject instance.

Alternatively, as the comments suggest (Thanks MK10), you could use the Stream#anyMatch method:

public boolean containsName(final List<MyObject> list, final String name){
    return list.stream().anyMatch(o -> o.getName().equals(name));
}

It appears you might be a bit confused as to how the .Add method works. I will refer directly to your code in my explanation.

Basically in C#, the .Add method of a List of objects does not COPY new added objects into the list, it merely copies a reference to the object (it's address) into the List. So the reason every value in the list is pointing to the same value is because you've only created 1 new DyObj. So your list essentially looks like this.

DyObjectsList[0] = &DyObj; // pointing to DyObj
DyObjectsList[1] = &DyObj; // pointing to the same DyObj
DyObjectsList[2] = &DyObj; // pointing to the same DyObj

...

The easiest way to fix your code is to create a new DyObj for every .Add. Putting the new inside of the block with the .Add would accomplish this goal in this particular instance.

var DyObjectsList = new List<dynamic>; 
if (condition1) { 
    dynamic DyObj = new ExpandoObject(); 
    DyObj.Required = true; 
    DyObj.Message = "Message 1"; 
    DyObjectsList .Add(DyObj); 
} 
if (condition2) { 
    dynamic DyObj = new ExpandoObject(); 
    DyObj.Required = false; 
    DyObj.Message = "Message 2"; 
    DyObjectsList .Add(DyObj); 
} 

your resulting List essentially looks like this

DyObjectsList[0] = &DyObj0; // pointing to a DyObj
DyObjectsList[1] = &DyObj1; // pointing to a different DyObj
DyObjectsList[2] = &DyObj2; // pointing to another DyObj

Now in some other languages this approach wouldn't work, because as you leave the block, the objects declared in the scope of the block could go out of scope and be destroyed. Thus you would be left with a collection of pointers, pointing to garbage.

However in C#, if a reference to the new DyObjs exists when you leave the block (and they do exist in your List because of the .Add operation) then C# does not release the memory associated with that pointer. Therefore the Objects you created in that block persist and your List contains pointers to valid objects and your code works.

A perl oneliner would do: perl -i.bak -pe 's/[^[:ascii:]]//g' <your file>

-i says that the file is going to be edited inplace, and the backup is going to be saved with extension .bak.

abline(h=mean(x))

for a horizontal line (use v instead of h for vertical if you orient your boxplot horizontally), or

points(mean(x))

for a point. Use the parameter pch to change the symbol. You may want to colour them to improve visibility too.

Note that these are called after you have drawn the boxplot.

If you are using the formula interface, you would have to construct the vector of means. For example, taking the first example from ?boxplot:

boxplot(count ~ spray, data = InsectSprays, col = "lightgray")
means <- tapply(InsectSprays$count,InsectSprays$spray,mean)
points(means,col="red",pch=18)

If your data contains missing values, you might want to replace the last argument of the tapply function with function(x) mean(x,na.rm=T)

I got same problem... and I did it.

My code before:

<link rel="stylesheet" href="../css/style.default.css" type="text/css" />

And the problem solved after I changed my code into this:

<link rel="stylesheet" href="css/style.default.css" type="text/css" />

So I think "href=../" is not allowed, because I don't have problem when I use "../" in "src=../"

I did also write a Single Linked List based on some tutorial, which has the basic two Node and Linked List classes, and some additional methods for insertion, delete, reverse, sorting, and such.

It's not the best or easiest, works OK though.

Predicate.not( … )

java-11 offers a new method Predicate#not

So you can negate the method reference:

Stream<String> s = ...;
long nonEmptyStrings = s.filter(Predicate.not(String::isEmpty)).count();

If you are using RHEL/CentOS 7 (the OP was not, but I thought I'd share the solution for my case), then you will need to use firewalld instead of the iptables service mentioned in other answers.

firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --reload

And then check that it is running with:

firewall-cmd --permanent --zone=public --list-all

It should list 80/tcp under ports

This is a never ending story that reflect the limits (an myth) of "interoperability and portability over all".

What the program should return to indicate "success" should be defined by who is receiving the value (the Operating system, or the process that invoked the program) not by a language specification.

But programmers likes to write code in "portable way" and hence they invent their own model for the concept of "operating system" defining symbolic values to return.

Now, in a many-to-many scenario (where many languages serve to write programs to many system) the correspondence between the language convention for "success" and the operating system one (that no one can grant to be always the same) should be handled by the specific implementation of a library for a specific target platform.

But - unfortunatly - these concept where not that clear at the time the C language was deployed (mainly to write the UNIX kernel), and Gigagrams of books where written by saying "return 0 means success", since that was true on the OS at that time having a C compiler.

From then on, no clear standardization was ever made on how such a correspondence should be handled. C and C++ has their own definition of "return values" but no-one grant a proper OS translation (or better: no compiler documentation say anything about it). 0 means success if true for UNIX - LINUX and -for independent reasons- for Windows as well, and this cover 90% of the existing "consumer computers", that - in the most of the cases - disregard the return value (so we can discuss for decades, bu no-one will ever notice!)

Inside this scenario, before taking a decision, ask these questions: - Am I interested to communicate something to my caller about my existing? (If I just always return 0 ... there is no clue behind the all thing) - Is my caller having conventions about this communication ? (Note that a single value is not a convention: that doesn't allow any information representation)

If both of this answer are no, probably the good solution is don't write the main return statement at all. (And let the compiler to decide, in respect to the target is working to).

If no convention are in place 0=success meet the most of the situations (and using symbols may be problematic, if they introduce a convention).

If conventions are in place, ensure to use symbolic constants that are coherent with them (and ensure convention coherence, not value coherence, between platforms).

I'm here in general only to find out that through dict it is necessary to work inside setattr XD

Another perspective for doing it on Linux... here is how to do it so that the resulting single file contains the decrypted private key so that something like HAProxy can use it without prompting you for passphrase.

openssl pkcs12 -in file.pfx -out file.pem -nodes

Then you can configure HAProxy to use the file.pem file.

This is an EDIT from previous version where I had these multiple steps until I realized the -nodes option just simply bypasses the private key encryption. But I'm leaving it here as it may just help with teaching.

openssl pkcs12 -in file.pfx -out file.nokey.pem -nokeys
openssl pkcs12 -in file.pfx -out file.withkey.pem
openssl rsa -in file.withkey.pem -out file.key
cat file.nokey.pem file.key > file.combo.pem

1. The 1st step prompts you for the password to open the PFX.
2. The 2nd step prompts you for that plus also to make up a passphrase for the key.
3. The 3rd step prompts you to enter the passphrase you just made up to store decrypted.
4. The 4th puts it all together into 1 file.

Then you can configure HAProxy to use the file.combo.pem file.

The reason why you need 2 separate steps where you indicate a file with the key and another without the key, is because if you have a file which has both the encrypted and decrypted key, something like HAProxy still prompts you to type in the passphrase when it uses it.

You can use HttpServletRequest.getScheme() to retrieve either "http" or "https".

Using it along with HttpServletRequest.getServerName() should be enough to rebuild the portion of the URL you need.

You don't need to explicitly put the port in the URL if you're using the standard ones (80 for http and 443 for https).

Edit: If your servlet container is behind a reverse proxy or load balancer that terminates the SSL, it's a bit trickier because the requests are forwarded to the servlet container as plain http. You have a few options:

1) Use HttpServletRequest.getHeader("x-forwarded-proto") instead; this only works if your load balancer sets the header correctly (Apache should afaik).

2) Configure a RemoteIpValve in JBoss/Tomcat that will make getScheme() work as expected. Again, this will only work if the load balancer sets the correct headers.

3) If the above don't work, you could configure two different connectors in Tomcat/JBoss, one for http and one for https, as described in this article.

Here I can't see even a single correct answer for this question (in WinForms tag) and it's strange for such frequent question.

Items of a ListBox control may be DataRowView, Complex Objects, Anonymous types, primary types and other types. Underlying value of an item should be calculated base on ValueMember.

ListBox control has a GetItemText which helps you to get the item text regardless of the type of object you added as item. It really needs such GetItemValue method.

GetItemValue Extension Method

We can create GetItemValue Extension Method to get item value which works like GetItemText:

using System;
using System.Windows.Forms;
using System.ComponentModel;
public static class ListControlExtensions
{
    public static object GetItemValue(this ListControl list, object item)
    {
        if (item == null)
            throw new ArgumentNullException("item");

        if (string.IsNullOrEmpty(list.ValueMember))
            return item;

        var property = TypeDescriptor.GetProperties(item)[list.ValueMember];
        if (property == null)
            throw new ArgumentException(
                string.Format("item doesn't contain '{0}' property or column.",
                list.ValueMember));
        return property.GetValue(item);
    }
}

Using above method you don't need to worry about settings of ListBox and it will return expected Value for an item. It works with List<T>, Array, ArrayList, DataTable, List of Anonymous Types, list of primary types and all other lists which you can use as data source. Here is an example of usage:

//Gets underlying value at index 2 based on settings
this.listBox1.GetItemValue(this.listBox1.Items[2]);

Since we created the GetItemValue method as an extension method, when you want to use the method, don't forget to include the namespace which you put the class in.

This method is applicable on ComboBox and CheckedListBox too.

if you are using tomcat you may try this

<servlet-mapping>

    <http-method>POST</http-method>

</servlet-mapping>

in addition to <servlet-name> and <url-mapping>

Because your question is phrased regarding your error message and not whatever your function is trying to accomplish, I will address the error.

- is the 'binary operator' your error is referencing, and either CurrentDay or MA (or both) are non-numeric.

A binary operation is a calculation that takes two values (operands) and produces another value (see wikipedia for more). + is one such operator: "1 + 1" takes two operands (1 and 1) and produces another value (2). Note that the produced value isn't necessarily different from the operands (e.g., 1 + 0 = 1).

R only knows how to apply + (and other binary operators, such as -) to numeric arguments:

> 1 + 1
[1] 2
> 1 + 'one'
Error in 1 + "one" : non-numeric argument to binary operator

When you see that error message, it means that you are (or the function you're calling is) trying to perform a binary operation with something that isn't a number.

EDIT:

Your error lies in the use of [ instead of [[. Because Day is a list, subsetting with [ will return a list, not a numeric vector. [[, however, returns an object of the class of the item contained in the list:

> Day <- Transaction(1, 2)["b"]
> class(Day)
[1] "list"
> Day + 1
Error in Day + 1 : non-numeric argument to binary operator

> Day2 <- Transaction(1, 2)[["b"]]
> class(Day2)
[1] "numeric"
> Day2 + 1
[1] 3

Transaction, as you've defined it, returns a list of two vectors. Above, Day is a list contain one vector. Day2, however, is simply a vector.

By default the last expression of a function will be returned. In your example there is another expression after the point, where you want your return value. If you want to return anything prior to your last expression, you still have to use return.

You could modify your example like this, to return a Boolean from the first part

def balanceMain(elem: List[Char]): Boolean = {
  if (elem.isEmpty) {
    // == is a Boolean resulting function as well, so your can write it this way
    count == 0
  } else {
    // keep the rest in this block, the last value will be returned as well
    if (elem.head == "(") {
      balanceMain(elem.tail, open, count + 1)
    }
    // some more statements
    ...
    // just don't forget your Boolean in the end
    someBoolExpression
  }
}

Interface and Abstract Class are the two different ways to achieve Abstraction in OOP Languages.

Interface provides 100% abstraction, i.e all methods are abstract.

Abstract class provides 0 to 100% abstraction, i.e it may have or may not have abstract methods.

We can use Interface when we want all the functionality of a type to be implemented by the client.

We can use Abstract Class when some common functionality can be provided by Abstract Class implementer and client will be given chance to implement what he needs actually.

Lots of answers here, but some don't take into account

• file names with spaces, newlines, or control characters in them
• file names that start with hyphens (imagine a file called -l)
• hidden files, that start with a dot (if the glob was *.log instead of log*
• directories that match the glob (e.g. a directory called logs that matches log*)
• empty directories (i.e. the result is 0)
• extremely large directories (listing them all could exhaust memory)

Here's a solution that handles all of them:

ls 2>/dev/null -Ubad1 -- log* | wc -l

Explanation:

• -U causes ls to not sort the entries, meaning it doesn't need to load the entire directory listing in memory
• -b prints C-style escapes for nongraphic characters, crucially causing newlines to be printed as \n.
• -a prints out all files, even hidden files (not strictly needed when the glob log* implies no hidden files)
• -d prints out directories without attempting to list the contents of the directory, which is what ls normally would do
• -1 makes sure that it's on one column (ls does this automatically when writing to a pipe, so it's not strictly necessary)
• 2>/dev/null redirects stderr so that if there are 0 log files, ignore the error message. (Note that shopt -s nullglob would cause ls to list the entire working directory instead.)
• wc -l consumes the directory listing as it's being generated, so the output of ls is never in memory at any point in time.
• -- File names are separated from the command using -- so as not to be understood as arguments to ls (in case log* is removed)

The shell will expand log* to the full list of files, which may exhaust memory if it's a lot of files, so then running it through grep is be better:

ls -Uba1 | grep ^log | wc -l

This last one handles extremely large directories of files without using a lot of memory (albeit it does use a subshell). The -d is no longer necessary, because it's only listing the contents of the current directory.

The previously mentioned wmic command is the way to go, as it is installed by default in recent versions of Windows.

Here is my small improvement to generalize it, by retrieving the current name from the environment:

wmic computersystem where name="%COMPUTERNAME%" 
     call rename name="NEW-NAME"

NOTE: The command must be given in one line, but I've broken it into two to make scrolling unnecessary. As @rbeede mentions you'll have to reboot to complete the update.

I ended up implementing my own adapter to wrap any other adapter and provide methods to add header and footer views.

Created a gist here: HeaderViewRecyclerAdapter.java

The main feature I wanted was a similar interface to a ListView, so I wanted to be able to inflate the views in my Fragment and add them to the RecyclerView in onCreateView. This is done by creating a HeaderViewRecyclerAdapter passing the adapter to be wrapped, and calling addHeaderView and addFooterView passing your inflated views. Then set the HeaderViewRecyclerAdapter instance as the adapter on the RecyclerView.

An extra requirement was that I needed to be able to easily swap out adapters while keeping the headers and footers, I didn't want to have multiple adapters with multiple instances of these headers and footers. So you can call setAdapter to change the wrapped adapter leaving the headers and footers intact, with the RecyclerView being notified of the change.

The problem might be with your firewall or antivirus.

1. Disable all network connection
2. Disable firewall
3. Disable Antivirus

Make sure they all disabled.

Run your script in Eclipse. If it works, then 2 and 3 might be the culprit. For me, it was comodo firewall. I created a filter for Adb.exe

Could you try a newer plugin; on the maven site:

<version>3.0</version>

I saw the following too:

<compilerVersion>1.7</compilerVersion>

You guessed right, HTTP Headers are not part of the URL.

And when you type a URL in the browser the request will be issued with standard headers. Anyway REST Apis are not meant to be consumed by typing the endpoint in the address bar of a browser.

The most common scenario is that your server consumes a third party REST Api.

To do so your server-side code forges a proper GET (/PUT/POST/DELETE) request pointing to a given endpoint (URL) setting (when needed, like your case) some headers and finally (maybe) sending some data (as typically occurrs in a POST request for example).

The code to forge the request, send it and finally get the response back depends on your server side language.

If you want to test a REST Api you may use curl tool from the command line.

curl makes a request and outputs the response to stdout (unless otherwise instructed).

In your case the test request would be issued like this:

$curl -H "Accept: application/json" 'http://localhost:8080/otp/routers/default/plan?fromPlace=52.5895,13.2836&toPlace=52.5461,13.3588&date=2017/04/04&time=12:00:00'

The H or --header directive sets a header and its value.

From version 9.1.4 you only need to import ReactiveFormsModule

https://angular.io/guide/reactive-forms

XMLStarlet or another XPath engine is the correct tool for this job.

For instance, with data.xml containing the following:

<root>
  <item> 
    <title>15:54:57 - George:</title>
    <description>Diane DeConn? You saw Diane DeConn!</description> 
  </item> 
  <item> 
    <title>15:55:17 - Jerry:</title> 
    <description>Something huh?</description>
  </item>
</root>

...you can extract only the first title with the following:

xmlstarlet sel -t -m '//title[1]' -v . -n <data.xml

Trying to use sed for this job is troublesome. For instance, the regex-based approaches won't work if the title has attributes; won't handle CDATA sections; won't correctly recognize namespace mappings; can't determine whether a portion of the XML documented is commented out; won't unescape attribute references (such as changing Brewster & Jobs to Brewster & Jobs), and so forth.

WMIC

wmic is a very complete tool

wmic diskdrive list

provide a (too much) detailed list, for instance

for less info

wmic diskdrive list brief 

C

Sebastian Godelet mentions in the comments:

In C:

system("wmic diskdrive list");

As commented, you can also call the WinAPI, but... as shown in "How to obtain data from WMI using a C Application?", this is quite complex (and generally done with C++, not C).

Or with PowerShell:

You need to add a gradle.settings file to your root project structure, after that when you "Open Module settings" you will the menu aligned to your gradle.settings. When importing a project to Android Studio, it doesn't create this file for you. Sometimes it's usually better to start a clean project and move your code there, it's usually easier to achieve.

Try this:

Open PgAdmin -> Files -> Open pgpass.conf

You would get the path of pgpass.conf at the bottom of the window. Go to that location and open this file, you can find your password there.

Reference

If the above does not work, you may consider trying this:

 1. edit pg_hba.conf to allow trust authorization temporarily
 2. Reload the config file (pg_ctl reload)
 3. Connect and issue ALTER ROLE / PASSWORD to set the new password
 4. edit pg_hba.conf again and restore the previous settings
 5. Reload the config file again

The only thing that worked for me:

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable().authorizeRequests().anyRequest().permitAll();
    }

and

security.ignored=/**

Could be that the properties part is redundant or can be done in code, but had no time to experiment. Anyway is temporary.


- Line Feed and 
 Carriage Return

These HTML entities will insert a new line or carriage return inside a text area.

Take a peek at the man page for sort...

   -n, --numeric-sort
          compare according to string numerical value

So here is an example...

sort -n filename

It's simple-

SELECT empname,
       empid,
       (SELECT COUNT (profileid)
          FROM profile
         WHERE profile.empid = employee.empid)
           AS number_of_profiles
  FROM employee;

It is even simpler when you use a table join like this:

  SELECT e.empname, e.empid, COUNT (p.profileid) AS number_of_profiles
    FROM employee e LEFT JOIN profile p ON e.empid = p.empid
GROUP BY e.empname, e.empid;

Explanation for the subquery:

Essentially, a subquery in a select gets a scalar value and passes it to the main query. A subquery in select is not allowed to pass more than one row and more than one column, which is a restriction. Here, we are passing a count to the main query, which, as we know, would always be only a number- a scalar value. If a value is not found, the subquery returns null to the main query. Moreover, a subquery can access columns from the from clause of the main query, as shown in my query where employee.empid is passed from the outer query to the inner query.

Edit:

When you use a subquery in a select clause, Oracle essentially treats it as a left join (you can see this in the explain plan for your query), with the cardinality of the rows being just one on the right for every row in the left.

Explanation for the left join

A left join is very handy, especially when you want to replace the select subquery due to its restrictions. There are no restrictions here on the number of rows of the tables in either side of the LEFT JOIN keyword.

For more information read Oracle Docs on subqueries and left join or left outer join.

Really great advise, except that the SAME error CAN occur simply by missing the critical script include on your root page

example:

page: index.html

   np-app="saleApp"

Missing

<script src="./ordersController.js"></script>

When a Route is told what controller and view to serve up:

 .when('/orders/:customerId', {
     controller: 'OrdersController',
     templateUrl: 'views/orders.html'
 })

So essential the undefined controller issue CAN occur in this accidental mistake of not even referencing the controller!

On Linux use below to test (it would replace the whitespaces with comma)

 sed 's/\s/,/g' /tmp/test.txt | head

later you can take the output into the file using below command:

sed 's/\s/,/g' /tmp/test.txt > /tmp/test_final.txt

PS: test is the file which you want to use

This worked for me: Top Menu -> File -> Invalidate Caches/Restart

You can use the Test-Path cmd-let. So something like...

if(!(Test-Path [oldLocation]) -and !(Test-Path [newLocation]))
{
    Write-Host "$file doesn't exist in both locations."
}

Yes there is using the following code will allow you to apply a blurring effect to the specified image and also it will allow you to choose the amount of blurring.

img {
  -webkit-filter: blur(10px);
    filter: blur(10px);
}

Another technique to consider if you want to compare a file to the last commit which is more pedantic:

git diff master myfile.txt

The advantage with this technique is you can also compare to the penultimate commit with:

git diff master^ myfile.txt

and the one before that:

git diff master^^ myfile.txt

Also you can substitute '~' for the caret '^' character and 'you branch name' for 'master' if you are not on the master branch.

As a general rule of thumb, I use 1 cm margins when producing pdfs. I work in the geospatial industry and produce pdf maps that reference a specific geographic scale. Therefore, I do not have the option to 'fit document to printable area,' because this would make the reference scale inaccurate. You must also realize that when you fit to printable area, you are fitting your already existing margins inside the printer margins, so you end up with double margins. Make your margins the right size and your documents will print perfectly. Many modern printers can print with margins less than 3 mm, so 1 cm as a general rule should be sufficient. However, if it is a high profile job, get the specs of the printer you will be printing with and ensure that your margins are adequate. All you need is the brand and model number and you can find spec sheets through a google search.

This works for any object, not just functions:

IF OBJECT_ID('YourObjectName') IS NOT NULL 

then just add your flavor of object, as in:

IF OBJECT_ID('YourFunction') IS NOT NULL
   DROP FUNCTION YourFunction

1. Populate "Code Signing" in both "Project" and "Targets" section
2. Select valid entries in "Code Signing Identity" in both "Debug" and "Release"
3. Under "Debug" select you Developer certificate
4. Under "Release" select your Distributor certificate

Following these 4 steps always solves my issues.

I looked and found a cross browser way:

function myFunction(){_x000D_
  if(window.innerWidth !== undefined && window.innerHeight !== undefined) { _x000D_
    var w = window.innerWidth;_x000D_
    var h = window.innerHeight;_x000D_
  } else {  _x000D_
    var w = document.documentElement.clientWidth;_x000D_
    var h = document.documentElement.clientHeight;_x000D_
  }_x000D_
  var txt = "Page size: width=" + w + ", height=" + h;_x000D_
  document.getElementById("demo").innerHTML = txt;_x000D_
}

I got this error, with angular 7, what helped me is, From the windows power shell I run the command:

then again I reopen my VS Code, on it's terminal I run the same command npm uninstall node-sass and npm install node-sass

I'd like to add to OJ's kind clarifications.

Virtual inheritance doesn't come without a price. Like with all things virtual, you get a performance hit. There is a way around this performance hit that is possibly less elegant.

Instead of breaking the diamond by deriving virtually, you can add another layer to the diamond, to get something like this:

   B
  / \
D11 D12
 |   |
D21 D22
 \   /
  DD

None of the classes inherit virtually, all inherit publicly. Classes D21 and D22 will then hide virtual function f() which is ambiguous for DD, perhaps by declaring the function private. They'd each define a wrapper function, f1() and f2() respectively, each calling class-local (private) f(), thus resolving conflicts. Class DD calls f1() if it wants D11::f() and f2() if it wants D12::f(). If you define the wrappers inline you'll probably get about zero overhead.

Of course, if you can change D11 and D12 then you can do the same trick inside these classes, but often that is not the case.

Try this:

print cast(getdate() as date )

i have just discovered, android studio 3.0.1 has no sdk during the installation. because during the installation, it doesn't give sdk as part of install able unlike in recent versions of android studio.

This error comes when you only have JRE installed instead of JDK in your JAVA_HOME variable. Unfortunately, you cannot have both of them installed in the same variable so you just need to overwrite the variable with new JDK installation path.

The process should be the same as the way you had JRE installed

You could use base64:

function randomString(length)
{
    var rtn = "";

    do {
        rtn += btoa("" + Math.floor(Math.random() * 100000)).substring(0, length);
    }
    while(rtn.length < length);

    return rtn;
}

First you have to Remove cache in your browser

Then open terminal and run the following command:

sudo apt-get install php-gettext
sudo nano /etc/nginx/sites-available/default

Then add the following code in the default file:

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /usr/share/nginx/html;
    index index.php index.html index.htm;

    server_name localhost;

    location / {

}

If any mismatch just correction and restart Nginx from terminal by the following command

sudo systemctl restart nginx

Then go to browser and Enjoy ...

Adding another entry for the debate about whether batch normalization should be called before or after the non-linear activation:

In addition to the original paper using batch normalization before the activation, Bengio's book Deep Learning, section 8.7.1 gives some reasoning for why applying batch normalization after the activation (or directly before the input to the next layer) may cause some issues:

It is natural to wonder whether we should apply batch normalization to the input X, or to the transformed value XW+b. Io?e and Szegedy (2015) recommend the latter. More speci?cally, XW+b should be replaced by a normalized version of XW. The bias term should be omitted because it becomes redundant with the ß parameter applied by the batch normalization reparameterization. The input to a layer is usually the output of a nonlinear activation function such as the recti?ed linear function in a previous layer. The statistics of the input are thus more non-Gaussian and less amenable to standardization by linear operations.

In other words, if we use a relu activation, all negative values are mapped to zero. This will likely result in a mean value that is already very close to zero, but the distribution of the remaining data will be heavily skewed to the right. Trying to normalize that data to a nice bell-shaped curve probably won't give the best results. For activations outside of the relu family this may not be as big of an issue.

Keep in mind that there are reports of models getting better results when using batch normalization after the activation, while others get best results when the batch normalization is placed before the activation. It is probably best to test your model using both configurations, and if batch normalization after activation gives a significant decrease in validation loss, use that configuration instead.

You can match those three groups separately, and make sure that they all present. Also, [^\w] seems a bit too broad, but if that's what you want you might want to replace it with \W.

That's because your input string can’t be converted according to the encoding rules (strict by default).

I don't know, but I always encoded using directly unicode() constructor, at least that's the ways at the official documentation:

unicode(your_str, errors="ignore")

had the same problem; my issue was selinux was set to enforcing.

I kept getting the "failed to open stream: Permission denied" error even after chmoding to 777 and making sure all parent folders had execute permissions for the apache user. Turns out my issue was that selinux was set to enforcing (I'm on centos7), this is a devbox so I turned it off.

In openSUSE 19.2 installing the patterns-hpc-development_node package fixed this issue for me.

They have already answered how to use a global variable.

I will tell you why the use of global variables is a bad idea as a result of this question carried out in stackoverflow in Spanish.

Explicit translation of the text in Spanish:

Impact of the change

The problem with global variables is that they create hidden dependencies. When it comes to large applications, you yourself do not know / remember / you are clear about the objects you have and their relationships.

So, you can not have a clear notion of how many objects your global variable is using. And if you want to change something of the global variable, for example, the meaning of each of its possible values, or its type? How many classes or compilation units will that change affect? If the amount is small, it may be worth making the change. If the impact will be great, it may be worth looking for another solution.

But what is the impact? Because a global variable can be used anywhere in the code, it can be very difficult to measure it.

In addition, always try to have a variable with the shortest possible life time, so that the amount of code that makes use of that variable is the minimum possible, and thus better understand its purpose, and who modifies it.

A global variable lasts for the duration of the program, and therefore, anyone can use the variable, either to read it, or even worse, to change its value, making it more difficult to know what value the variable will have at any given program point. .

Order of destruction

Another problem is the order of destruction. Variables are always destroyed in reverse order of their creation, whether they are local or global / static variables (an exception is the primitive types, int,enums, etc., which are never destroyed if they are global / static until they end the program).

The problem is that it is difficult to know the order of construction of the global (or static) variables. In principle, it is indeterminate.

If all your global / static variables are in a single compilation unit (that is, you only have a .cpp), then the order of construction is the same as the writing one (that is, variables defined before, are built before).

But if you have more than one .cpp each with its own global / static variables, the global construction order is indeterminate. Of course, the order in each compilation unit (each .cpp) in particular, is respected: if the global variableA is defined before B,A will be built before B, but It is possible that between A andB variables of other .cpp are initialized. For example, if you have three units with the following global / static variables:

Image1

In the executable it could be created in this order (or in any other order as long as the relative order is respected within each .cpp):

Image2

Why is this important? Because if there are relations between different static global objects, for example, that some use others in their destructors, perhaps, in the destructor of a global variable, you use another global object from another compilation unit that turns out to be already destroyed ( have been built later).

Hidden dependencies and * test cases *

I tried to find the source that I will use in this example, but I can not find it (anyway, it was to exemplify the use of singletons, although the example is applicable to global and static variables). Hidden dependencies also create new problems related to controlling the behavior of an object, if it depends on the state of a global variable.

Imagine you have a payment system, and you want to test it to see how it works, since you need to make changes, and the code is from another person (or yours, but from a few years ago). You open a new main, and you call the corresponding function of your global object that provides a bank payment service with a card, and it turns out that you enter your data and they charge you. How, in a simple test, have I used a production version? How can I do a simple payment test?

After asking other co-workers, it turns out that you have to "mark true", a global bool that indicates whether we are in test mode or not, before beginning the collection process. Your object that provides the payment service depends on another object that provides the mode of payment, and that dependency occurs in an invisible way for the programmer.

In other words, the global variables (or singletones), make it impossible to pass to "test mode", since global variables can not be replaced by "testing" instances (unless you modify the code where said code is created or defined). global variable, but we assume that the tests are done without modifying the mother code).

Solution

This is solved by means of what is called * dependency injection *, which consists in passing as a parameter all the dependencies that an object needs in its constructor or in the corresponding method. In this way, the programmer ** sees ** what has to happen to him, since he has to write it in code, making the developers gain a lot of time.

If there are too many global objects, and there are too many parameters in the functions that need them, you can always group your "global objects" into a class, style * factory *, that builds and returns the instance of the "global object" (simulated) that you want , passing the factory as a parameter to the objects that need the global object as dependence.

If you pass to test mode, you can always create a testing factory (which returns different versions of the same objects), and pass it as a parameter without having to modify the target class.

But is it always bad?

Not necessarily, there may be good uses for global variables. For example, constant values ??(the PI value). Being a constant value, there is no risk of not knowing its value at a given point in the program by any type of modification from another module. In addition, constant values ??tend to be primitive and are unlikely to change their definition.

It is more convenient, in this case, to use global variables to avoid having to pass the variables as parameters, simplifying the signatures of the functions.

Another can be non-intrusive "global" services, such as a logging class (saving what happens in a file, which is usually optional and configurable in a program, and therefore does not affect the application's nuclear behavior), or std :: cout,std :: cin or std :: cerr, which are also global objects.

Any other thing, even if its life time coincides almost with that of the program, always pass it as a parameter. Even the variable could be global in a module, only in it without any other having access, but that, in any case, the dependencies are always present as parameters.

If you want a interactive tree, you can use tig. It can be installed by brew on OSX and apt-get in Linux.

brew install tig
tig

This is what you get:

I installed Node.js on bluehost.com (a shared server) using:

wget <path to download file>
tar -xf <gzip file>
mv <gzip_file_dir> node

This will download the tar file, extract to a directory and then rename that directory to the name 'node' to make it easier to use.

then

./node/bin/npm install jt-js-sample

Returns:
npm WARN engine [email protected]: wanted: {"node":"0.10.x"} (current: {"node":"0.12.4","npm":"2.10.1"})
[email protected] node_modules/jt-js-sample
+-- [email protected] ([email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected])

I can now use the commands:

# ~/node/bin/node -v
v0.12.4

# ~/node/bin/npm -v
2.10.1

For security reasons, I have renamed my node directory to something else.

%w(foo bar) is a shortcut for ["foo", "bar"]. Meaning it's a notation to write an array of strings separated by spaces instead of commas and without quotes around them. You can find a list of ways of writing literals in zenspider's quickref.

Standardize your module's imports and exports then you won't risk hitting problems with misspelled property names.

module.exports = Component should become export default Component.

CommonJS uses module.exports as a convention, however, this means that you are just working with a regular Javascript object and you are able to set the value of any key you want (whether that's exports, exoprts or exprots). There are no runtime or compile-time checks to tell you that you've messed up.

If you use ES6 (ES2015) syntax instead, then you are working with syntax and keywords. If you accidentally type exoprt default Component then it will give you a compile error to let you know.

In your case, you can simplify the Speaker component.

import React from 'react';

export default React.createClass({
  render() {
    return (
      <h1>Speaker</h1>
    )
  }
});

The way I use these operators:

||, && are for boolean logic. or, and are for control flow. E.g.

do_smth if may_be || may_be -- we evaluate the condition here

do_smth or do_smth_else -- we define the workflow, which is equivalent to do_smth_else unless do_smth

to give a simple example:

> puts "a" && "b"
b

> puts 'a' and 'b'
a

A well-known idiom in Rails is render and return. It's a shortcut for saying return if render, while render && return won't work. See "Avoiding Double Render Errors" in the Rails documentation for more information.

Another way is to select a column with the columns array:

In [5]: df = pd.DataFrame([[1,2], [3,4]], columns=['a', 'b'])

In [6]: df
Out[6]: 
   a  b
0  1  2
1  3  4

In [7]: df[df.columns[0]]
Out[7]: 
0    1
1    3
Name: a, dtype: int64

try this

$ cmd='mysql AMORE -u root --password="password" -h localhost -e "select host from amoreconfig"'
$ eval $cmd

For those wishing to install a small number of packages in conda with pip then using,

sudo $(which pip) install <instert_package_name>

worked for me.

Explainaton

It seems, for me anyway, that which pip is very reliable for finding the conda env pip path to where you are. However, when using sudo, this seems to redirect paths or otherwise break this.

Using the $(which pip) executes this independently of the sudo or any of the commands and is akin to running /home/<username>/(mini)conda(3)/envs/<env_name>/pip in Linux. This is because $() is run separately and the text output added to the outer command.

It's a good practice to use a config file like this:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <connectionStrings>
    <add name="MyConnString" connectionString="Data Source=(local);Initial Catalog=MyDB; Integrated Security=SSPI" ;Timeout=30"/>
  </connectionStrings>
  <appSettings>
    <add key="BackupFolder" value="C:/temp/"/>
  </appSettings>
</configuration> 

Your C# code will be something like this:

// read connectionstring from config file
var connectionString = ConfigurationManager.ConnectionStrings["MyConnString"].ConnectionString; 

// read backup folder from config file ("C:/temp/")
var backupFolder = ConfigurationManager.AppSettings["BackupFolder"];

var sqlConStrBuilder = new SqlConnectionStringBuilder(connectionString);

// set backupfilename (you will get something like: "C:/temp/MyDatabase-2013-12-07.bak")
var backupFileName = String.Format("{0}{1}-{2}.bak", 
    backupFolder, sqlConStrBuilder.InitialCatalog, 
    DateTime.Now.ToString("yyyy-MM-dd"));

using (var connection = new SqlConnection(sqlConStrBuilder.ConnectionString))
{
    var query = String.Format("BACKUP DATABASE {0} TO DISK='{1}'", 
        sqlConStrBuilder.InitialCatalog, backupFileName);

    using (var command = new SqlCommand(query, connection))
    {
        connection.Open();
        command.ExecuteNonQuery();
    }
}

Try this way:

public class Bin {
  public static void main(String[] args) {
    System.out.println(toBinary(0x94, 8));
  }

  public static String toBinary(int a, int bits) {
    if (--bits > 0)
        return toBinary(a>>1, bits)+((a&0x1)==0?"0":"1");
    else 
        return (a&0x1)==0?"0":"1";
  }

}

I was having this issue when I was using Application Verifier to verify my win service. Even after I closed App Ver my service was blocked from deletion. Only removing the service from App Ver resolved the issue and service was deleted right away. Looks like some process still using your service after you tried to delete one.

Check this: USING FOR LOOP

for a in range(5):
    x='A'
    val=chr(ord(x) + a)
    print(val)

Using Java 8+ features we can write the code in few lines:

protected static Collection<Path> find(String fileName, String searchDirectory) throws IOException {
    try (Stream<Path> files = Files.walk(Paths.get(searchDirectory))) {
        return files
                .filter(f -> f.getFileName().toString().equals(fileName))
                .collect(Collectors.toList());

    }
}

Files.walk returns a Stream<Path> which is "walking the file tree rooted at" the given searchDirectory. To select the desired files only a filter is applied on the Stream files. It compares the file name of a Path with the given fileName.

Note that the documentation of Files.walk requires

This method must be used within a try-with-resources statement or similar control structure to ensure that the stream's open directories are closed promptly after the stream's operations have completed.

I'm using the try-resource-statement.

For advanced searches an alternative is to use a PathMatcher:

protected static Collection<Path> find(String searchDirectory, PathMatcher matcher) throws IOException {
    try (Stream<Path> files = Files.walk(Paths.get(searchDirectory))) {
        return files
                .filter(matcher::matches)
                .collect(Collectors.toList());

    }
}

An example how to use it to find a certain file:

public static void main(String[] args) throws IOException {
    String searchDirectory = args[0];
    String fileName = args[1];
    PathMatcher matcher = FileSystems.getDefault().getPathMatcher("regex:.*" + fileName);
    Collection<Path> find = find(searchDirectory, matcher);
    System.out.println(find);
}

Yes, you can use this query (Instead of 'Specialist' and 'Developer', type any strings you want separated by comma and change employees table with your table)

SELECT * FROM employees em
    WHERE EXISTS (select 1 from table(sys.dbms_debug_vc2coll('Specialist', 'Developer')) mt where em.job like ('%' || mt.column_value || '%'));

Why my query is better than the accepted answer: You don't need a CREATE TABLE permission to run it. This can be executed with just SELECT permissions.

Numeric defines the TOTAL number of digits, and then the number after the decimal.

A numeric(3,2) can only hold up to 9.99.

Not quite

int main(void)
{
   #if 0
     the apostrophe ' causes a warning
   #endif
   return 0;
}

It shows "t.c:4:19: warning: missing terminating ' character" with gcc 4.2.4

Found one solution for WIFI (works for Android 4.3, 4.4):

1. Connect to WIFI network (e.g. 'Alex')
2. Settings->WIFI
3. Long tap on connected network's name (e.g. on 'Alex')
4. Modify network config-> Show advanced options
5. Set proxy settings

Because System.exit() is just another method to the compiler. It doesn't read ahead and figure out that the whole program will quit at that point (the JVM quits). Your OS or shell can read the integer that is passed back in the System.exit() method. It is standard for 0 to mean "program quit and everything went OK" and any other value to notify an error occurred. It is up to the developer to document these return values for any users.

return on the other hand is a reserved key word that the compiler knows well. return returns a value and ends the current function's run moving back up the stack to the function that invoked it (if any). In your code above it returns void as you have not supplied anything to return.

JLabel label = new JLabel("fax", SwingConstants.RIGHT);

It seems the issue is in "-f ($_.Partition.Size/1GB)}}" If you want the value in MB then change the 1GB to 1MB.

Another one-liner using Python swapping:

df, df.columns = df[1:] , df.iloc[0]

This won't reset the index

Although, the opposite won't work as expected df.columns, df = df.iloc[0], df[1:]

From MySQL docs:

A character set is a set of symbols and encodings. A collation is a set of rules for comparing characters in a character set. Let's make the distinction clear with an example of an imaginary character set.

Suppose that we have an alphabet with four letters: 'A', 'B', 'a', 'b'. We give each letter a number: 'A' = 0, 'B' = 1, 'a' = 2, 'b' = 3. The letter 'A' is a symbol, the number 0 is the encoding for 'A', and the combination of all four letters and their encodings is a character set.

Now, suppose that we want to compare two string values, 'A' and 'B'. The simplest way to do this is to look at the encodings: 0 for 'A' and 1 for 'B'. Because 0 is less than 1, we say 'A' is less than 'B'. Now, what we've just done is apply a collation to our character set. The collation is a set of rules (only one rule in this case): "compare the encodings." We call this simplest of all possible collations a binary collation.

But what if we want to say that the lowercase and uppercase letters are equivalent? Then we would have at least two rules: (1) treat the lowercase letters 'a' and 'b' as equivalent to 'A' and 'B'; (2) then compare the encodings. We call this a case-insensitive collation. It's a little more complex than a binary collation.

In real life, most character sets have many characters: not just 'A' and 'B' but whole alphabets, sometimes multiple alphabets or eastern writing systems with thousands of characters, along with many special symbols and punctuation marks. Also in real life, most collations have many rules: not just case insensitivity but also accent insensitivity (an "accent" is a mark attached to a character as in German 'ö') and multiple-character mappings (such as the rule that 'ö' = 'OE' in one of the two German collations).

It's complaining about

COUNT(DISTINCT dNum) AS ud 

inside the subquery. Only one column can be returned from the subquery unless you are performing an exists query. I'm not sure why you want to do a count on the same column twice, superficially it looks redundant to what you are doing. The subquery here is only a filter it is not the same as a join. i.e. you use it to restrict data, not to specify what columns to get back.

All of the examples listed above for sed break on one platform or another. None of them work with the version of sed shipped on Macs.

However, Perl's regex works the same on any machine with Perl installed:

perl -pe 's/\s+/\n/g' file.txt

If you want to save the output:

perl -pe 's/\s+/\n/g' file.txt > newfile.txt

If you want only unique occurrences of words:

perl -pe 's/\s+/\n/g' file.txt | sort -u > newfile.txt

If you don't care about IE =6, you could use pure CSS ...

.forum:hover { background-color: #380606; }

.forum { color: white; }_x000D_
.forum:hover { background-color: #380606 !important; }_x000D_
/* we use !important here to override specificity. see http://stackoverflow.com/q/5805040/ */_x000D_
_x000D_
#blue { background-color: blue; }

<meta charset=utf-8>_x000D_
_x000D_
<p class="forum" style="background-color:red;">Red</p>_x000D_
<p class="forum" style="background:green;">Green</p>_x000D_
<p class="forum" id="blue">Blue</p>

With jQuery, usually it is better to create a specific class for this style:

.forum_hover { background-color: #380606; }

and then apply the class on mouseover, and remove it on mouseout.

$('.forum').hover(function(){$(this).toggleClass('forum_hover');});

$(document).ready(function(){_x000D_
  $('.forum').hover(function(){$(this).toggleClass('forum_hover');});_x000D_
});

.forum_hover { background-color: #380606 !important; }_x000D_
_x000D_
.forum { color: white; }_x000D_
#blue { background-color: blue; }

<p class="forum" style="background:green;">Green</p>_x000D_
<p class="forum" id="blue">Blue</p>

If you must not modify the class, you could save the original background color in .data():

  $('.forum').data('bgcolor', '#380606').hover(function(){
    var $this = $(this);
    var newBgc = $this.data('bgcolor');
    $this.data('bgcolor', $this.css('background-color')).css('background-color', newBgc);
  });

$(document).ready(function(){_x000D_

In laravel-4, you can use the template comment syntax to define/set variables.

Comment syntax is {{-- anything here is comment --}} and it is rendered by blade engine as

<?php /* anything here is comment */ ?>

so with little trick we can use it to define variables, for example

{{-- */$i=0;/* --}}

will be rendered by bladeas <?php /* */$i=0;/* */ ?> which sets the variable for us. Without changing any line of code.

You can change

Range("B3:B65536").Copy Destination:=Sheets("DB").Range("B" & lastrow)

to

Range("B3:B65536").Copy 
Sheets("DB").Range("B" & lastrow).PasteSpecial xlPasteValues

BTW, if you have xls file (excel 2003), you would get an error if your lastrow would be greater 3.

Try to use this code instead:

Sub Get_Data()
    Dim lastrowDB As Long, lastrow As Long
    Dim arr1, arr2, i As Integer

    With Sheets("DB")
        lastrowDB = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
    End With

    arr1 = Array("B", "C", "D", "E", "F", "AH", "AI", "AJ", "J", "P", "AF")
    arr2 = Array("B", "A", "C", "P", "D", "E", "G", "F", "H", "I", "J")

    For i = LBound(arr1) To UBound(arr1)
        With Sheets("Sheet1")
             lastrow = Application.Max(3, .Cells(.Rows.Count, arr1(i)).End(xlUp).Row)
             .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
             Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues
        End With
    Next
    Application.CutCopyMode = False
End Sub

Note, above code determines last non empty row on DB sheet in column A (variable lastrowDB). If you need to find lastrow for each destination column in DB sheet, use next modification:

For i = LBound(arr1) To UBound(arr1)
   With Sheets("DB")
       lastrowDB = .Cells(.Rows.Count, arr2(i)).End(xlUp).Row + 1
   End With

   ' NEXT CODE

Next

You could also use next approach instead Copy/PasteSpecial. Replace

.Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues

with

Sheets("DB").Range(arr2(i) & lastrowDB).Resize(lastrow - 2).Value = _
      .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Value

This probably isn't the most elegant way to do it, but it gets the job done.

On the "How to do it" part:

I think the introduction to ScalaTest does good job of illustrating different styles of unit tests.

On the "When to do it" part:

Unit testing is not only for testing. By doing unit testing you also force the design of the software into something that is unit testable. Many people are of the opinion that this design is for the most part Good Design(TM) regardless of other benefits from testing.

So one reason to do unit test is to force your design into something that hopefully will be easier to maintain that what it would be had you not designed it for unit testing.

I use an extension method for this. My extension method first checks to see if the enumeration is null and if so creates an empty list. This allows you to do a foreach on it without explicitly having to check for null.

Here is a very contrived example:

IEnumerable<string> stringEnumerable = null;
StringBuilder csv = new StringBuilder();
stringEnumerable.ToNonNullList().ForEach(str=> csv.Append(str).Append(","));

Here is the extension method:

public static List<T> ToNonNullList<T>(this IEnumerable<T> obj)
{
    return obj == null ? new List<T>() : obj.ToList();
}

I've had success with

<span class="someclass"></span>

Caveat : the class must already exist on the site.

Maybe you can try creating the unexisting columns and calling union (unionAll for Spark 1.6 or lower):

cols = ['id', 'uniform', 'normal', 'normal_2']    

df_1_new = df_1.withColumn("normal_2", lit(None)).select(cols)
df_2_new = df_2.withColumn("normal", lit(None)).select(cols)

result = df_1_new.union(df_2_new)

Reading your comments took me to a dirty fix. This is not a right way, I know, but can be a work around.

$(function() {
    $( "#inputFieldId" ).autocomplete({
        source: function( event, ui ) {
            alert("do your functions here");
            return false;
        }
    });
});

You have:

foreach (var category in Model.Categories)

and then

@foreach (var product in Model)

Based on that view and model it seems that Model is of type Product if yes then the second foreach is not valid. Actually the first one could be the one that is invalid if you return a collection of Product.

UPDATE:

You are right, I am returning the model of type Product. Also, I do understand what is wrong now that you've pointed it out. How am I supposed to do what I'm trying to do then if I can't do it this way?

I'm surprised your code compiles when you said you are returning a model of Product type. Here's how you can do it:

@foreach (var category in Model)
{
    <h3><u>@category.Name</u></h3>

    <div>
        <ul>    
            @foreach (var product in category.Products)
            {
                <li>
                    put the rest of your code
                </li>
            }
        </ul>
    </div>
}

That suggest that instead of returning a Product, you return a collection of Category with Products. Something like this in EF:

// I am typing it here directly 
// so I'm not sure if this is the correct syntax.
// I assume you know how to do this,
// anyway this should give you an idea.
context.Categories.Include(o=>o.Product)

Well any Javascript object functions sort-of like a "map"

randomObject['hello'] = 'world';

Typically people build simple objects for the purpose:

var myMap = {};

// ...

myMap[newKey] = newValue;

edit — well the problem with having an explicit "put" function is that you'd then have to go to pains to avoid having the function itself look like part of the map. It's not really a Javascripty thing to do.

13 Feb 2014 — modern JavaScript has facilities for creating object properties that aren't enumerable, and it's pretty easy to do. However, it's still the case that a "put" property, enumerable or not, would claim the property name "put" and make it unavailable. That is, there's still only one namespace per object.

Typings can be configured with the ~/.typingsrc config file. (~ means your home directory)

After finding this issue on github: https://github.com/typings/typings/issues/120, I was able to hack around this issue by creating ~/.typingsrc and setting this configuration:

{
  "proxy": "http://<server>:<port>",
  "rejectUnauthorized": false
}

It also seemed to work without the proxy setting, so maybe it was able to pick that up from the environment somewhere.

This is not a true solution, but was enough for typings to ignore the corporate firewall issues so that I could continue working. I'm sure there is a better solution out there.

If the aim is to just load the contents inside your application, you don't even need to use wget:

$xmlData = file_get_contents('http://user:[email protected]/file.xml');

Note that this function will not work if allow_url_fopen is disabled (it's enabled by default) inside either php.ini or the web server configuration (e.g. httpd.conf).

If your host explicitly disables it or if you're writing a library, it's advisable to either use cURL or a library that abstracts the functionality, such as Guzzle.

use GuzzleHttp\Client;

$client = new Client([
  'base_url' => 'http://example.com',
  'defaults' => [
    'auth'    => ['user', 'pass'],
]]);

$xmlData = $client->get('/file.xml');

Take a look at http://developer.android.com/reference/org/json/JSONTokener.html

This might fix your issue.

You can force the annotation library in your test using:

androidTestCompile 'com.android.support:support-annotations:23.1.0'

Something like this:

  // Force usage of support annotations in the test app, since it is internally used by the runner module.
  androidTestCompile 'com.android.support:support-annotations:23.1.0'
  androidTestCompile 'com.android.support.test:runner:0.4.1'
  androidTestCompile 'com.android.support.test:rules:0.4.1'
  androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
  androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.1'
  androidTestCompile 'com.android.support.test.espresso:espresso-web:2.2.1'

Another solution is to use this in the top level file:

configurations.all {
    resolutionStrategy.force 'com.android.support:support-annotations:23.1.0'
}

I tried using phyatt's AspectRatioPixmapLabel class, but experienced a few problems:

• Sometimes my app entered an infinite loop of resize events. I traced this back to the call of QLabel::setPixmap(...) inside the resizeEvent method, because QLabel actually calls updateGeometry inside setPixmap, which may trigger resize events...
• heightForWidth seemed to be ignored by the containing widget (a QScrollArea in my case) until I started setting a size policy for the label, explicitly calling policy.setHeightForWidth(true)
• I want the label to never grow more than the original pixmap size
• QLabel's implementation of minimumSizeHint() does some magic for labels containing text, but always resets the size policy to the default one, so I had to overwrite it

That said, here is my solution. I found that I could just use setScaledContents(true) and let QLabel handle the resizing. Of course, this depends on the containing widget / layout honoring the heightForWidth.

In cmd when you use > or >> the output will be only written on the file. Is it possible to see the output in the cmd windows and also save it in a file. Something similar if you use teraterm, when you can start saving all the log in a file meanwhile you use the console and view it (only for ssh, telnet and serial).

I got this error message on lambda expression that was using Linq to filter a collection of objects. When I inspected the collection I noticed that its members weren't populated - in the Locals window, expanding them just showed "...". Ultimately the problem was in the repository method that initially populated the collection - Dapper was trying to automatically map a property of a nested object. I fixed the Dapper query to handle the multi-mapping and that fixed the memory error.

The stack pointer stores the address of the most recent entry that was pushed onto the stack.

To push a value onto the stack, the stack pointer is incremented to point to the next physical memory address, and the new value is copied to that address in memory.

To pop a value from the stack, the value is copied from the address of the stack pointer, and the stack pointer is decremented, pointing it to the next available item in the stack.

The most typical use of a hardware stack is to store the return address of a subroutine call. When the subroutine is finished executing, the return address is popped off the top of the stack and placed in the Program Counter register, causing the processor to resume execution at the next instruction following the call to the subroutine.

1) JTable knows JCheckbox with built-in Boolean TableCellRenderers and TableCellEditor by default, then there is contraproductive declare something about that,

2) AbstractTableModel should be useful, where is in the JTable required to reduce/restrict/change nested and inherits methods by default implemented in the DefaultTableModel,

3) consider using DefaultTableModel, (if you are not sure about how to works) instead of AbstractTableModel,

Using jquery, you can avoid copy paste and cut using this

$('.textboxClass').on('copy paste cut', function(e) {
    e.preventDefault();
});

Here's a version using the excellent requests library:

from requests import session

payload = {
    'action': 'login',
    'username': USERNAME,
    'password': PASSWORD
}

with session() as c:
    c.post('http://example.com/login.php', data=payload)
    response = c.get('http://example.com/protected_page.php')
    print(response.headers)
    print(response.text)

In addition to what was said by Howard

You have to keep in mind that Google encodes spaces as + To avoid this, the ulr must be encoded in RFC 3986, which means spaces encoded at %20, for example:

https://example.com/My Folder/image 1.jpg to https://example.com/My%20Folder/image%201.jpg

You're not supplying it with an array in your example. The following compiles fine:

public @interface SampleAnnotation {
    String[] sampleValues();
}

public class Values {
    public static final String val0 = "A";
    public static final String val1 = "B";

    @SampleAnnotation(sampleValues={ val0, val1 })
    public void foo() {
    }
}

Sould look like:

<td colspan ='4'><img src="\Pics\H.gif" alt="" border='3' height='100' width='100' /></td>

.

<td> need to be closed with </td> <img /> is (in most case) an empty tag. The closing tag is replacede by /> instead... like for br's

<br/>

Your html structure is plain worng (sorry), but this will probably turn into a really bad cross-brwoser compatibility. Also, Encapsulate the value of your attributes with quotes and avoid using upercase in tags.

Firstly, get the Android SDK location in Android Studio : Android Studio -> Preferences -> Appearance & Behaviour -> System Settings -> Android SDK -> Android SDK Location

Then execute the following commands in terminal

export ANDROID_HOME=Paste here your SDK location

export PATH=$PATH:$ANDROID_HOME/bin

It is done.

For Windows, first install the git base from here: https://git-scm.com/downloads

Next, set the environment variable:

1. Press Windows+R and type sysdm.cpl
2. Select advance -> Environment variable
3. Select path-> edit the path and paste the below line:

C:\Program Files\Git\git-bash.exe

To test it, open the command window: press Windows+R, type cmd and then type ssh.

Yes, -f is the most suitable option for this.

Series.reset_index with name argument

Often the use case comes up where a Series needs to be promoted to a DataFrame. But if the Series has no name, then reset_index will result in something like,

s = pd.Series([1, 2, 3], index=['a', 'b', 'c']).rename_axis('A')
s

A
a    1
b    2
c    3
dtype: int64

s.reset_index()

   A  0
0  a  1
1  b  2
2  c  3

Where you see the column name is "0". We can fix this be specifying a name parameter.

s.reset_index(name='B')

   A  B
0  a  1
1  b  2
2  c  3

s.reset_index(name='list')

   A  list
0  a     1
1  b     2
2  c     3

Series.to_frame

If you want to create a DataFrame without promoting the index to a column, use Series.to_frame, as suggested in this answer. This also supports a name parameter.

s.to_frame(name='B')

   B
A   
a  1
b  2
c  3

pd.DataFrame Constructor

You can also do the same thing as Series.to_frame by specifying a columns param:

pd.DataFrame(s, columns=['B'])

   B
A   
a  1
b  2
c  3

To do a cross server query, check out the system stored procedure: sp_addlinkedserver in the help files.

Once the server is linked you can run a query against it.

A variation on @gauss256's answer, deleting .svn, worked for me:

rm -rf troublesome_folder/.svn
svn add troublesome_folder
svn commit

Before Gauss's solution I tried @jwir3's approach and got no joy:

svn cleanup
svn cleanup *
svn cleanup troublesome_folder
svn add --force troublesome_folder
svn commit

Put http.request.method == "POST" in the display filter of wireshark to only show POST requests. Click on the packet, then expand the Hypertext Transfer Protocol field. The POST data will be right there on top.

app.get is called when the HTTP method is set to GET, whereas app.use is called regardless of the HTTP method, and therefore defines a layer which is on top of all the other RESTful types which the express packages gives you access to.

Use this command:

dd if=$INPUT-FILE of=$OUTPUT-FILE bs=$BLOCK-SIZE count=$NUM-BLOCKS

To create a big (empty) file, set $INPUT-FILE=/dev/zero.
Total size of the file will be $BLOCK-SIZE * $NUM-BLOCKS.
New file created will be $OUTPUT-FILE.

I've also found it useful to access object attributes where the attribute names vary by some iterator. For example, I have used the pattern below for a set of time periods: hour, day, month.

$periods=array('hour', 'day', 'month');
foreach ($periods as $period)
{
    $this->{'value_'.$period}=1;
}

This same pattern can also be used to access class methods. Just build up the method name in the same manner, using strings and string variables.

You could easily argue to just use an array for the value storage by period. If this application were PHP only, I would agree. I use this pattern when the class attributes map to fields in a database table. While it is possible to store arrays in a database using serialization, it is inefficient, and pointless if the individual fields must be indexed. I often add an array of the field names, keyed by the iterator, for the best of both worlds.

class timevalues
{
                             // Database table values:
    public $value_hour;      // maps to values.value_hour
    public $value_day;       // maps to values.value_day
    public $value_month;     // maps to values.value_month
    public $values=array();

    public function __construct()
    {
        $this->value_hour=0;
        $this->value_day=0;
        $this->value_month=0;
        $this->values=array(
            'hour'=>$this->value_hour,
            'day'=>$this->value_day,
            'month'=>$this->value_month,
        );
    }
}

Response is already parsed, you don't need to parse it again. if you parse it again it will give you "unexpected token o". if you need to get it as string, you could use JSON.stringify()

If you actually have a database, this is the most-simple way:

var lsPetOwners = ( from person in context.People
                    from pets in context.Pets
                        .Where(mypet => mypet.Owner == person.ID) 
                        .DefaultIfEmpty()
                     select new { OwnerName = person.Name, Pet = pets.Name }
                   ).ToList();

Depends on what you mean by 'empty':

members[0] = '\0';

Kurts answer needed to be slightly modified to work for me.

First, on ubuntu: sudo apt-get install python-imaging

Then:

from PIL import Image
im=Image.open(filepath)
im.size # (width,height) tuple

Check out the handbook for more info.

There are some things to be considered in your code.

First, write those headers correctly. You will never see any server sending Content-type:application/pdf, the header is Content-Type: application/pdf, spaced, with capitalized first letters etc.

The file name in Content-Disposition is the file name only, not the full path to it, and altrough I don't know if its mandatory or not, this name comes wrapped in " not '. Also, your last ' is missing.

Content-Disposition: inline implies the file should be displayed, not downloaded. Use attachment instead.

In addition, make the file extension in upper case to make it compatible with some mobile devices. (Update: Pretty sure only Blackberries had this problem, but the world moved on from those so this may be no longer a concern)

All that being said, your code should look more like this:

<?php

    $filename = './pdf/jobs/pdffile.pdf';

    $fileinfo = pathinfo($filename);
    $sendname = $fileinfo['filename'] . '.' . strtoupper($fileinfo['extension']);

    header('Content-Type: application/pdf');
    header("Content-Disposition: attachment; filename=\"$sendname\"");
    header('Content-Length: ' . filesize($filename));
    readfile($filename);

Content-Length is optional but is also important if you want the user to be able to keep track of the download progress and detect if the download was interrupted. But when using it you have to make sure you won't be send anything along with the file data. Make sure there is absolutely nothing before <?php or after ?>, not even an empty line.

You can also try to use a Polyfill like Fixed-Sticky. Especially when you are using Bootstrap4 the affix component is no longer included:

Dropped the Affix jQuery plugin. We recommend using a position: sticky polyfill instead.

Also ensure that your controllers are defined within script tags toward the bottom of your index.html just before the closing tag for body.

 <!-- build:js({.tmp,app}) scripts/scripts.js -->
    <script src="scripts/app.js"></script>
    <script src="scripts/controllers/main.js"></script>
    <script src="scripts/controllers/Administration.js"></script>
    <script src="scripts/controllers/Leaderboard.js"></script>
    <script src="scripts/controllers/Login.js"></script>
    <script src="scripts/controllers/registration.js"></script>

provided everything is spelled "correctly" (the same) on your specific.html, specific.js and app.js pages this should resolve your issue.

It looks like you just hard-coded the row and column; otherwise, a couple of small tweaks, and I think you're there:

Dim sh As Worksheet
Dim rw As Range
Dim RowCount As Integer

RowCount = 0

Set sh = ActiveSheet
For Each rw In sh.Rows

  If sh.Cells(rw.Row, 1).Value = "" Then
    Exit For
  End If

  RowCount = RowCount + 1

Next rw

MsgBox (RowCount)

In Angular 7, the (ngModelChange)="eventHandler()" will fire before the value bound to [(ngModel)]="value" is changed while the (change)="eventHandler()" will fire after the value bound to [(ngModel)]="value" is changed.

Another feature is between:

Select * from table where date between '2009/01/30' and '2009/03/30'

<div style="text-align:center">
    <span>Short text</span><br />
    <span>This is long text</span>
</div>

From the OP:

I finally reinstalled it from Java for OS X 2013-005. It solved this issue.

Hashes are a sequence of bits (128 bits, 160 bits, 256 bits, etc., depending on the algorithm). Your column should be binary-typed, not text/character-typed, if MySQL allows it (SQL Server datatype is binary(n) or varbinary(n)). You should also salt the hashes. Salts may be text or binary, and you will need a corresponding column.

In swift 4 : by overriding method

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        let storyboard = UIStoryboard(name : "Main", bundle: nil)
        let next vc = storyboard.instantiateViewController(withIdentifier: "nextvcIdentifier") as! NextViewController

       self.navigationController?.pushViewController(prayerVC, animated: true)
}

Just want to add my two cents on this old post:

In my opinion, almost all of relational database engines include a commit transaction execution automatically after execute a DDL command even when you have autocommit=false, So you don't need to start a transaction to avoid a potential truncated object creation because It is completely unnecessary.

A branch is actually a pointer that holds a commit ID such as 17a5. HEAD is a pointer to a branch the user is currently working on.

HEAD has a reference filw which looks like this:

ref:

You can check these files by accessing .git/HEAD .git/refs that are in the repository you are working in.

I had read yesterday that the issue was fixed for someone when that person cleared cookies. I had tried that but it did not work for me.

Checking the following section in DatabaseInterface.class.php,

        define(
            'PMA_MYSQL_INT_VERSION',
            PMA_Util::cacheGet('PMA_MYSQL_INT_VERSION', true)
        );

I figured that somehow cache is the problem. So, I remembered that I was restarting the service instead of doing a start and stop.

# restart the service
systemd restart php-fpm

# start and stop the service
systemd stop php-fpm
systemd start php-fpm

Doing a stop followed by a start fixed the issue for me.

try {
    File img = new File("somefile.png");
    BufferedImage image = ImageIO.read(img ); 
    System.out.println(image);
} catch (IOException e) { 
    e.printStackTrace(); 
}

Example output for my image file:

BufferedImage@5d391d: type = 5 ColorModel: #pixelBits = 24 
numComponents = 3 color 
space = java.awt.color.ICC_ColorSpace@50a649 
transparency = 1 
has alpha = false 
isAlphaPre = false 
ByteInterleavedRaster: 
width = 800 
height = 600 
#numDataElements 3 
dataOff[0] = 2

You can run System.out.println(object); on just about any object and get some information about it.

+ theme(plot.title = element_text(size=22))

Here is the full set of things you can change in element_text:

element_text(family = NULL, face = NULL, colour = NULL, size = NULL,
  hjust = NULL, vjust = NULL, angle = NULL, lineheight = NULL,
  color = NULL)

Because when you call $( "#form_id" ).submit(); it triggers the external submit handler which prevents the default action, instead use

$( "#form_id" )[0].submit();       

or

$form.submit();//declare `$form as a local variable by using var $form = this;

When you call the dom element's submit method programatically, it won't trigger the submit handlers attached to the element

Get all 3 jackson jars and add them to your build path:

https://mvnrepository.com/artifact/com.fasterxml.jackson.core

There is two way :

1) Using Glide library This is best way to load image from url because when you try to display same url in second time it will display from catch so improve app performance

Glide.with(context).load("YourUrl").into(imageView);

dependency : implementation 'com.github.bumptech.glide:glide:4.10.0'

2) Using Stream. Here you want to create bitmap from url image

URL url = new URL("YourUrl");
Bitmap bitmap = BitmapFactory.decodeStream(url.openConnection().getInputStream());
imageView.setImageBitmap(bitmap);

You can use the following regular expression to check if a string is base64 encoded or not:

^([A-Za-z0-9+/]{4})*([A-Za-z0-9+/]{3}=|[A-Za-z0-9+/]{2}==)?$

In base64 encoding, the character set is [A-Z, a-z, 0-9, and + /]. If the rest length is less than 4, the string is padded with '=' characters.

^([A-Za-z0-9+/]{4})* means the string starts with 0 or more base64 groups.

([A-Za-z0-9+/]{4}|[A-Za-z0-9+/]{3}=|[A-Za-z0-9+/]{2}==)$ means the string ends in one of three forms: [A-Za-z0-9+/]{4}, [A-Za-z0-9+/]{3}= or [A-Za-z0-9+/]{2}==.

I got the same errors. Mysql was running as a standalone application before I started phpMyAdmin.

I just stopped mysql Then sudo /Applications/XAMPP/xamppfiles/xampp stop sudo /Applications/XAMPP/xamppfiles/xampp start

It worked fine

Here is the example of one Object, For your case you have to use JSONArray.

public static final String JSON_STRING="{\"employee\":{\"name\":\"Sachin\",\"salary\":56000}}";  
try{  
   JSONObject emp=(new JSONObject(JSON_STRING)).getJSONObject("employee");  
   String empname=emp.getString("name");  
   int empsalary=emp.getInt("salary");  

   String str="Employee Name:"+empname+"\n"+"Employee Salary:"+empsalary;  
   textView1.setText(str);  

}catch (Exception e) {e.printStackTrace();}  
   //Do when JSON has problem.
}

I don't have time but tried to give an idea. If you still can't do it, then I will help.

I think your cron is not correct. According to what you described, you may need to change cron schedule to

*/5 * * * *

What you put in your schedule now mean it will poll the SCM at 5 past of every hour.

You can easily increase your VM's RAM by modifying the memory property of config.vm.provider section in your vagrant file.

config.vm.provider "virtualbox" do |vb|
 vb.memory = "4096"
end

This allocates about 4GB of RAM to your VM. You can change this according to your requirement. For example, following setting would allocate 2GB of RAM to your VM.

config.vm.provider "virtualbox" do |vb|
 vb.memory = "2048"
end

Try removing the config.vm.customize ["modifyvm", :id, "--memory", 1024] in your file, and adding the above code.

For the network configuration, try modifying the config.vm.network :hostonly, "199.188.44.20" in your file toconfig.vm.network "private_network", ip: "199.188.44.20"

Try this, it show the nearest points to provided coordinates (within 50 km). It works perfectly:

SELECT m.name,
    m.lat, m.lon,
    p.distance_unit
             * DEGREES(ACOS(COS(RADIANS(p.latpoint))
             * COS(RADIANS(m.lat))
             * COS(RADIANS(p.longpoint) - RADIANS(m.lon))
             + SIN(RADIANS(p.latpoint))
             * SIN(RADIANS(m.lat)))) AS distance_in_km
FROM <table_name> AS m
JOIN (
      SELECT <userLat> AS latpoint, <userLon> AS longpoint,
             50.0 AS radius, 111.045 AS distance_unit
     ) AS p ON 1=1
WHERE m.lat
BETWEEN p.latpoint  - (p.radius / p.distance_unit)
    AND p.latpoint  + (p.radius / p.distance_unit)
    AND m.lon BETWEEN p.longpoint - (p.radius / (p.distance_unit * COS(RADIANS(p.latpoint))))
    AND p.longpoint + (p.radius / (p.distance_unit * COS(RADIANS(p.latpoint))))
ORDER BY distance_in_km

Just change <table_name>. <userLat> and <userLon>

Extending @RobBednark's solution to a specific Windows + PuTTY scenario, you can do so:

1. Generate SSH key pair with PuTTYgen (following Manually generating your SSH key in Windows), saving it to a PPK file;

2. With the context menu in Windows Explorer, choose Edit with PuTTYgen. It will prompt for a password.

If you type the wrong password, it will just prompt again.

Note, if you like to type, use the following command on a folder that contains the PPK file: puttygen private-key.ppk -y.

In my case I chose the Force Update checkbox while pushing. It worked like a charm.

No you cannot. The only thing you can do is to insert content. Like so:

p:after {
    content: "yo";
}

In ExtJs, you can use

xtype: 'image'

to render a image.

Here is a fiddle showing rendering of binary data with extjs.

atob -- > converts ascii to binary

btoa -- > converts binary to ascii

Ext.application({
    name: 'Fiddle',

    launch: function () {
        var srcBase64 = "data:image/jpeg;base64," + btoa(atob("iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP8H8hYDwAFegHS8+X7mgAAAABJRU5ErkJggg=="));

        Ext.create("Ext.panel.Panel", {
            title: "Test",
            renderTo: Ext.getBody(),
            height: 400,
            items: [{
                xtype: 'image',
                width: 100,
                height: 100,
                src: srcBase64
            }]
        })
    }
});

The following MySQL query will itself produce a single query that will truncate all tables in a given database. It bypasses FOREIGN keys:

SELECT CONCAT(
         'SET FOREIGN_KEY_CHECKS=0; ',
         GROUP_CONCAT(dropTableSql SEPARATOR '; '), '; ',
         'SET FOREIGN_KEY_CHECKS=1;'
       ) as dropAllTablesSql
FROM   ( SELECT  Concat('TRUNCATE TABLE ', table_schema, '.', TABLE_NAME) AS dropTableSql
         FROM    INFORMATION_SCHEMA.TABLES
         WHERE   table_schema = 'DATABASE_NAME' ) as queries

Faced exactly the same issue while upgrading my application from java 6 to java 8 on tomcat 7.0.19. After upgrading the tomcat to 7.0.59, this issue is resolved.

In Postgres, you can also use the special DISTINCT ON (expression) syntax:

SELECT DISTINCT ON (cname) 
    cname, wmname, avg
FROM 
    makerar 
ORDER BY 
    cname, avg DESC ;

You need this instead:

if(s.contains("+"))

contains() method of String class does not take regular expression as a parameter, it takes normal text.

EDIT:

String s = "ddjdjdj+kfkfkf";

if(s.contains("+"))
{
    String parts[] = s.split("\\+");
    System.out.print(parts[0]);
}

OUTPUT:

ddjdjdj

I had my own instance of this error, and in my case none of the above solutions resolved the "cannot be resolved to a type" error by themselves, although they were necessary steps toward doing so. I found something silly that did though.

This seemed to be due a bug in Eclipse (Luna Service Release 1a (4.4.1) in my case). In the file where you're seeing the error, try saving after making and then undoing a trivial change (e.g. deleting one character and then typing it back in). For some reason this caused all my class references to resolve.

This is the code I have for moving an item down one place in a list:

if (this.folderImages.SelectedIndex > -1 && this.folderImages.SelectedIndex < this.folderImages.Items.Count - 1)
{
    string imageName = this.folderImages.SelectedItem as string;
    int index = this.folderImages.SelectedIndex;

    this.folderImages.Items.RemoveAt(index);
    this.folderImages.Items.Insert(index + 1, imageName);
    this.folderImages.SelectedIndex = index + 1;
 }

and this for moving it one place up:

if (this.folderImages.SelectedIndex > 0)
{
    string imageName = this.folderImages.SelectedItem as string;
    int index = this.folderImages.SelectedIndex;

    this.folderImages.Items.RemoveAt(index);
    this.folderImages.Items.Insert(index - 1, imageName);
    this.folderImages.SelectedIndex = index - 1;
}

folderImages is a ListBox of course so the list is a ListBox.ObjectCollection, not a List<T>, but it does inherit from IList so it should behave the same. Does this help?

Of course the former only works if the selected item is not the last item in the list and the latter if the selected item is not the first item.

You can ssh directly from the Terminal on Mac, but you need to use a .PEM key rather than the putty .PPK key. You can use PuttyGen on Windows to convert from .PEM to .PPK, I'm not sure about the other way around though.

You can also convert the key using putty for Mac via port or brew:

sudo port install putty

or

brew install putty

This will also install puttygen. To get puttygen to output a .PEM file:

puttygen privatekey.ppk -O private-openssh -o privatekey.pem

Once you have the key, open a terminal window and:

ssh -i privatekey.pem [email protected]

The private key must have tight security settings otherwise SSH complains. Make sure only the user can read the key.

chmod go-rw privatekey.pem

@zetysz and @Manish already fixed the problem. I am just putting this in an answer for future reference:

• pip refers to Python 2 as a default in Ubuntu, this means that pip install x will install the module for Python 2 and not for 3

• pip3 refers to Python 3, it will install the module for Python 3

FolderBrowserDialog fbd = new FolderBrowserDialog();

        DialogResult result = fbd.ShowDialog();

        string[] files = Directory.GetFiles(fbd.SelectedPath);
        string[] dirs = Directory.GetDirectories(fbd.SelectedPath);

        foreach (string item2 in dirs)
        {
            FileInfo f = new FileInfo(item2);

            listBox1.Items.Add(f.Name);

        }

        foreach (string item in files)
        {
            FileInfo f = new FileInfo(item);

            listBox1.Items.Add(f.Name);

        }

API is like the building blocks of some puzzling game that a child plays with to join blocks in different shapes and build something they can think of.

SDK, on the other hand, is a proper workshop where all of the development tools are available, rather than pre-shaped building blocks. In a workshop you have the actual tools and you are not limited to blocks, and can therefore make your own blocks, or can create something without any blocks to begin with.

coding without an SDK or API is like making everything from scratch without a workshop - you have to even make your own tools

As mentioned in the presentation at the I/O (about 4:05), Volley "is terrible" for large payloads. As I understand it that means not to use Volley for receiving/sending (big) files. Looking at the code it seems that it is not even designed to handle multipart form data (e.g. Request.java has getBodyContentType() with hardcoded "application/x-www-form-urlencoded"; HttpClientStack::createHttpRequest() can handle only byte[], etc...). Probably you will be able to create implementation that can handle multipart but If I were you I will just use HttpClient directly with MultipartEntity like:

    HttpPost req = new HttpPost(composeTargetUrl());
    MultipartEntity entity = new MultipartEntity();
    entity.addPart(POST_IMAGE_VAR_NAME, new FileBody(toUpload));
    try {
        entity.addPart(POST_SESSION_VAR_NAME, new StringBody(uploadSessionId));
    } catch (UnsupportedEncodingException e) {
        throw new RuntimeException(e);
    }
    req.setEntity(entity);

You may need newer HttpClient (i.e. not the built-in) or even better, use Volley with newer HttpClient

Good question.

True regular languages can not decide arbitrarily deeply nested well-formed parenthesis. If your alphabet contains '(' and ')' the goal is to decide if a string of these has well-formed matching parenthesis. Since this is a necessary requirement for regular expressions the answer is no.

However, if you loosen the requirement and add recursion you can probably do it. The reason is that the recursion can act as a stack letting you "count" the current nesting depth by pushing onto this stack.

Russ Cox wrote "Regular Expression Matching Can Be Simple And Fast" which is a wonderful treatise on regex engine implementation.

You can try this:

var d = new Date();
var t = d.toDateString().split(" ");
t[2] +" "+t[1]+" "+t[3];

SELECT *
FROM Table1 AS a
WHERE NOT EXISTS (
  SELECT *
  FROM Table2 AS b 
  WHERE a.FirstName=b.FirstName AND a.LastName=b.Last_Name
)

EXISTS will help you...

Neither a rebase nor a merge should overwrite anyone's changes (unless you choose to do so when resolving a conflict).

The usual approach while developing is

git checkout master
git pull
git checkout test
git log master.. # if you're curious
git merge origin/test # to update your local test from the fetch in the pull earlier

When you're ready to merge back into master,

git checkout master
git log ..test # if you're curious
git merge test
git push

If you're worried about breaking something on the merge, git merge --abort is there for you.

Using push and then pull as a means of merging is silly. I'm also not sure why you're pushing test to origin.

I have also faced the same problem and this is how i resolved it.

1. First of all you need to make sure that your node and npm versions are up to date. if not please upgrade your node and npm packages to latest versions.

   nvm install 12.18.3 // update node version through node version manager
   
   npm install npm // update your npm version to latest
   

2. Delete your node_modules folder and package-lock.json file.

3. Force clean the entire NPM cache by using following comand.

   npm cache clean --force
   

4. Re-Install all the dependencies.

   npm install
   

5. If above step didn't resolve your problem, try to re-install your dependencies after executing following command.

   npm rebuild

FIRST, if you want to be able to access man1.py from man1test.py AND manModules.py from man1.py, you need to properly setup your files as packages and modules.

Packages are a way of structuring Python’s module namespace by using “dotted module names”. For example, the module name A.B designates a submodule named B in a package named A.

...

When importing the package, Python searches through the directories on sys.path looking for the package subdirectory.

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path.

You need to set it up to something like this:

man
|- __init__.py
|- Mans
   |- __init__.py
   |- man1.py
|- MansTest
   |- __init.__.py
   |- SoftLib
      |- Soft
         |- __init__.py
         |- SoftWork
            |- __init__.py
            |- manModules.py
      |- Unittests
         |- __init__.py
         |- man1test.py

SECOND, for the "ModuleNotFoundError: No module named 'Soft'" error caused by from ...Mans import man1 in man1test.py, the documented solution to that is to add man1.py to sys.path since Mans is outside the MansTest package. See The Module Search Path from the Python documentation. But if you don't want to modify sys.path directly, you can also modify PYTHONPATH:

sys.path is initialized from these locations:

• The directory containing the input script (or the current directory when no file is specified).
• PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH).
• The installation-dependent default.

THIRD, for from ...MansTest.SoftLib import Soft which you said "was to facilitate the aforementioned import statement in man1.py", that's now how imports work. If you want to import Soft.SoftLib in man1.py, you have to setup man1.py to find Soft.SoftLib and import it there directly.

With that said, here's how I got it to work.

man1.py:

from Soft.SoftWork.manModules import *
# no change to import statement but need to add Soft to PYTHONPATH

def foo():
    print("called foo in man1.py")
    print("foo call module1 from manModules: " + module1())

man1test.py

# no need for "from ...MansTest.SoftLib import Soft" to facilitate importing..
from ...Mans import man1

man1.foo()

manModules.py

def module1():
    return "module1 in manModules"

Terminal output:

$ python3 -m man.MansTest.Unittests.man1test
Traceback (most recent call last):
  ...
    from ...Mans import man1
  File "/temp/man/Mans/man1.py", line 2, in <module>
    from Soft.SoftWork.manModules import *
ModuleNotFoundError: No module named 'Soft'

$ PYTHONPATH=$PYTHONPATH:/temp/man/MansTest/SoftLib
$ export PYTHONPATH
$ echo $PYTHONPATH
:/temp/man/MansTest/SoftLib
$ python3 -m man.MansTest.Unittests.man1test
called foo in man1.py
foo called module1 from manModules: module1 in manModules 

As a suggestion, maybe re-think the purpose of those SoftLib files. Is it some sort of "bridge" between man1.py and man1test.py? The way your files are setup right now, I don't think it's going to work as you expect it to be. Also, it's a bit confusing for the code-under-test (man1.py) to be importing stuff from under the test folder (MansTest).

The dict.items iterates over the key-value pairs of a dictionary. Therefore for key, value in dictionary.items() will loop over each pair. This is documented information and you can check it out in the official web page, or even easier, open a python console and type help(dict.items). And now, just as an example:

>>> d = {'hello': 34, 'world': 2999}
>>> for key, value in d.items():
...   print key, value
...
world 2999
hello 34

The AttributeError is an exception thrown when an object does not have the attribute you tried to access. The class dict does not have any predictors attribute (now you know where to check it :) ), and therefore it complains when you try to access it. As easy as that.

Powershell

For powershell, use #:

PS C:\> echo foo # This is a comment
foo

If your template.html file is just HTML and not a React component, then you can't require it in the same way you would do with a JS file.

However, if you are using Browserify — there is a transform called stringify which will allow you to require non-js files as strings. Once you have added the transform, you will be able to require HTML files and they will export as though they were just strings.

Once you have required the HTML file, you'll have to inject the HTML string into your component, using the dangerouslySetInnerHTML prop.

var __html = require('./template.html');
var template = { __html: __html };

React.module.exports = React.createClass({
  render: function() {
    return(
      <div dangerouslySetInnerHTML={template} />
    );
  }
});

This goes against a lot of what React is about though. It would be more natural to create your templates as React components with JSX, rather than as regular HTML files.

The JSX syntax makes it trivially easy to express structured data, like HTML, especially when you use stateless function components.

If your template.html file looked something like this

<div class='foo'>
  <h1>Hello</h1>
  <p>Some paragraph text</p>
  <button>Click</button>
</div>

Then you could convert it instead to a JSX file that looked like this.

module.exports = function(props) {
  return (
    <div className='foo'>
      <h1>Hello</h1>
      <p>Some paragraph text</p>
      <button>Click</button>
    </div>
  );
};

Then you can require and use it without needing stringify.

var Template = require('./template');

module.exports = React.createClass({
  render: function() {
    var bar = 'baz';
    return(
      <Template foo={bar}/>
    );
  }
});

It maintains all of the structure of the original file, but leverages the flexibility of React's props model and allows for compile time syntax checking, unlike a regular HTML file.

Use window.open():

<a onclick="window.open(document.URL, '_blank', 'location=yes,height=570,width=520,scrollbars=yes,status=yes');">
  Share Page
</a>

This will create a link titled Share Page which opens the current url in a new window with a height of 570 and width of 520.

Update: This will create a second context same as in applicationContext.xml

or you can add this code snippet to your web.xml

<servlet>
    <servlet-name>spring-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

instead of

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

public static int minIndex (ArrayList<Float> list) {
  return list.indexOf (Collections.min(list));
 }
System.out.println("Min = " + list.get(minIndex(list));

I would first suggest that you step back and look at organizing your plays to not require such complexity, but if you really really do, use the following:

   vars:
    myvariable: "{{[param1|default(''), param2|default(''), param3|default('')]|join(',')}}"

I was having this issue when using capistrano to deploy a rails app. The problem was that my user only had a jailed shell access in cpanel. Changing it to normal shell access fixed my problem.

If You're using php5.6 and Ubuntu 18.04 Then run these two commands in your terminal your errors will be solved definitely.

sudo apt-get install php5.6-gd

then restart your apache server by this command.

 sudo service apache2 restart

The "break" command does not work within an "if" statement.

If you remove the "break" command from your code and then test the code, you should find that the code works exactly the same without a "break" command as with one.

"Break" is designed for use inside loops (for, while, do-while, enhanced for and switch).
