A simple for loop which tests the checked property and appends the checked ones to a separate array. From there, you can process the array of checkboxesChecked further if needed.

// Pass the checkbox name to the function
function getCheckedBoxes(chkboxName) {
  var checkboxes = document.getElementsByName(chkboxName);
  var checkboxesChecked = [];
  // loop over them all
  for (var i=0; i<checkboxes.length; i++) {
     // And stick the checked ones onto an array...
     if (checkboxes[i].checked) {
        checkboxesChecked.push(checkboxes[i]);
     }
  }
  // Return the array if it is non-empty, or null
  return checkboxesChecked.length > 0 ? checkboxesChecked : null;
}

// Call as
var checkedBoxes = getCheckedBoxes("mycheckboxes");

Do you want coordinates relative to the screen or the application?

If it's within the application just use:

Mouse.GetPosition(Application.Current.MainWindow);

If not, I believe you can add a reference to System.Windows.Forms and use:

System.Windows.Forms.Control.MousePosition;

Whenever you use NULL you are really dealing with a Three-Valued logic.

Your first query returns results as the WHERE clause evaluates to:

    3 = 1 or 3 = 2 or 3 = 3 or 3 = null
which is:
    FALSE or FALSE or TRUE or UNKNOWN
which evaluates to 
    TRUE

The second one:

    3 <> 1 and 3 <> 2 and 3 <> null
which evaluates to:
    TRUE and TRUE and UNKNOWN
which evaluates to:
    UNKNOWN

The UNKNOWN is not the same as FALSE you can easily test it by calling:

select 'true' where 3 <> null
select 'true' where not (3 <> null)

Both queries will give you no results

If the UNKNOWN was the same as FALSE then assuming that the first query would give you FALSE the second would have to evaluate to TRUE as it would have been the same as NOT(FALSE).
That is not the case.

There is a very good article on this subject on SqlServerCentral.

The whole issue of NULLs and Three-Valued Logic can be a bit confusing at first but it is essential to understand in order to write correct queries in TSQL

Another article I would recommend is SQL Aggregate Functions and NULL.

1) Others (especially dirkgently) have noted that buffer needs to be allocated some memory space. For smallish values of N (say, N <= 4096), you can also allocate it on the stack:

#define BUFFER_SIZE 4096
char buffer[BUFFER_SIZE]

This saves you the worry of ensuring that you delete[] the buffer should an exception be thrown.

But remember that stacks are finite in size (so are heaps, but stacks are finiter), so you don't want to put too much there.

2) On a -1 return code, you should not simply return immediately (throwing an exception immediately is even more sketchy.) There are certain normal conditions that you need to handle, if your code is to be anything more than a short homework assignment. For example, EAGAIN may be returned in errno if no data is currently available on a non-blocking socket. Have a look at the man page for read(2).

This is all because you are not in the desired directory. You need to first get into the desired directory. Mine was angular-phonecat directory. So I typed in cd angular-phonecat and then npm install.

df.aree <- as.data.frame(t(df.aree))
colnames(df.aree) <- df.aree[1, ]
df.aree <- df.aree[-1, ]
df.aree$myfactor <- factor(row.names(df.aree))

I'm going to add an answer to try to clear up a few things here as there seems to be some confusion. The main issue is that people are asking the wrong question, or at least not being specific enough.

What does a computer's "domain" actually mean?

When we talk about a computer's "domain", there are several things that we might be referring to. What follows is not an exhaustive list, but it covers the most common cases:

• A user or computer security principal may belong to an Active Directory domain.
• The network stack's primary DNS search suffix may be referred to as the computer's "domain".
• A DNS name that resolves to the computer's IP address may be referred to as the computer's "domain".

Which one do I want?

This is highly dependent on what you are trying to do. The original poster of this question was looking for the computer's "Active Directory domain", which probably means they are looking for the domain to which either the computer's security principal or a user's security principal belongs. Generally you want these when you are trying to talk to Active Directory in some way. Note that the current user principal and the current computer principal are not necessarily in the same domain.

Pieter van Ginkel's answer is actually giving you the local network stack's primary DNS suffix (the same thing that's shown in the top section of the output of ipconfig /all). In the 99% case, this is probably the same as the domain to which both the computer's security principal and the currently authenticated user's principal belong - but not necessarily. Generally this is what you want when you are trying to talk to devices on the LAN, regardless of whether or not the devices are anything to do with Active Directory. For many applications, this will still be a "good enough" answer for talking to Active Directory.

The last option, a DNS name, is a lot fuzzier and more ambiguous than the other two. Anywhere between zero and infinity DNS records may resolve to a given IP address - and it's not necessarily even clear which IP address you are interested in. user2031519's answer refers to the value of HTTP_HOST, which is specifically useful when determining how the user resolved your HTTP server in order to send the request you are currently processing. This is almost certainly not what you want if you are trying to do anything with Active Directory.

How do I get them?

Domain of the current user security principal

This one's nice and simple, it's what Tim's answer is giving you.

System.Environment.UserDomainName

Domain of the current computer security principal

This is probably what the OP wanted, for this one we're going to have to ask Active Directory about it.

System.DirectoryServices.ActiveDirectory.Domain.GetComputerDomain()

This one will throw a ActiveDirectoryObjectNotFoundException if the local machine is not part of domain, or the domain controller cannot be contacted.

Network stack's primary DNS suffix

This is what Pieter van Ginkel's answer is giving you. It's probably not exactly what you want, but there's a good chance it's good enough for you - if it isn't, you probably already know why.

System.Net.NetworkInformation.IPGlobalProperties.GetIPGlobalProperties().DomainName

DNS name that resolves to the computer's IP address

This one's tricky and there's no single answer to it. If this is what you are after, comment below and I will happily discuss your use-case and help you to work out the best solution (and expand on this answer in the process).

You may use AddWithValue method like:

string connString = ConfigurationManager.ConnectionStrings["default"].ConnectionString;
MySqlConnection conn = new MySqlConnection(connString);
conn.Open();
MySqlCommand comm = conn.CreateCommand();
comm.CommandText = "INSERT INTO room(person,address) VALUES(@person, @address)";
comm.Parameters.AddWithValue("@person", "Myname");
comm.Parameters.AddWithValue("@address", "Myaddress");
comm.ExecuteNonQuery();
conn.Close();

OR

Try with ? instead of @, like:

string connString = ConfigurationManager.ConnectionStrings["default"].ConnectionString;
MySqlConnection conn = new MySqlConnection(connString);
conn.Open();
MySqlCommand comm = conn.CreateCommand();
comm.CommandText = "INSERT INTO room(person,address) VALUES(?person, ?address)";
comm.Parameters.Add("?person", "Myname");
comm.Parameters.Add("?address", "Myaddress");
comm.ExecuteNonQuery();
conn.Close();

Hope it helps...

If you used only $json_string = json_encode($data, JSON_PRETTY_PRINT);, you will get in the browser something like this (using the Facebook link from the question :) ):

but if you used a chrome Extension like JSONView (even without the PHP option above), then you get a more pretty readable debuggable solution where you can even Fold/Collapse each single JSON object easily like this:

You could also use

print(tbl_df(df), n=40)

or with the help of the pipe operator

df %>% tbl_df %>% print(n=40)

To print all rows specify tbl_df %>% print(n = Inf)

If you know what the sections are, you can do:

select top 10 * from table where section=1
union
select top 10 * from table where section=2
union
select top 10 * from table where section=3

The point for diamond operator is simply to reduce typing of code when declaring generic types. It doesn't have any effect on runtime whatsoever.

The only difference if you specify in Java 5 and 6,

List<String> list = new ArrayList();

is that you have to specify @SuppressWarnings("unchecked") to the list (otherwise you will get an unchecked cast warning). My understanding is that diamond operator is trying to make development easier. It's got nothing to do on runtime execution of generics at all.

In Java, a String is a reference to heap-allocated storage. Returning "ans" only returns the reference so there is no need for stack-allocated storage. In fact, there is no way in Java to allocate objects in stack storage.

I would change to this, though. You don't need "ans" at all.

return String.format("%d:%d", mins, secs);

Easiest way i found -

1. Uninstall current version
2. Download the appropriate .msi installer (x64 or x86) for the desired version from https://nodejs.org/download/release/

Powder's comment may go undetected like I missed it so many times,. So with the hope of making it more visible, I will re-iterate his point.

Sometimes using image = array(img).reshape(a,b,c,d) will reshape alright but from experience, my kernel crashes every time I try to use the new dimension in an operation. The safest to use is

np.expand_dims(img, axis=0)

It works perfect every time. I just can't explain why. This link has a great explanation and examples regarding its usage.

On Windows it can be found in the file "C:\Windows\System32\config\systemprofile\AppData\Local\Jenkins\.jenkins\secrets\initialAdminPassword"

(I know OP specified EC2 server, but this is now the first result on google when searching Jenkins Password)

I am not sure but when we have execute time out or command time out The client sends an "ABORT" to SQL Server then simply abandons the query processing. No transaction is rolled back, no locks are released. to solve this problem I Remove transaction in Stored-procedure and use SQL Transaction in my .Net Code To manage sqlException

Try the following syntax:

document.body.innerHTML += "<p>My new content</p>";

for bootstrap4 vertical center of few items

d-flex for flex rules

flex-column for vertical direction on items

justify-content-center for centering

style='height: 300px;' must have for set points where center be calc or use h-100 class

<div class="d-flex flex-column justify-content-center bg-secondary" style="
    height: 300px;
">
    <div class="p-2 bg-primary">Flex item</div>
    <div class="p-2 bg-primary">Flex item</div>
    <div class="p-2 bg-primary">Flex item</div>
  </div> 

I get the same error in WP when I use php ver 7.1.6 - just take your php version back to 7.0.20 and the error will disappear.

You can change background color and drop down icon like doing this way

Step1: In drawable folder make background.xml for border of spinner.

<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@android:color/transparent" />
<corners android:radius="5dp" />
<stroke
    android:width="1dp"
    android:color="@color/darkGray" />
</shape>  //edited

Step2: for layout design of spinner use this drop down icon or any image drop.pnj

  <RelativeLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_marginRight="3dp"
                    android:layout_weight=".28"
                    android:background="@drawable/spinner_border"
                    android:orientation="horizontal">

                    <Spinner
                        android:id="@+id/spinner2"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:layout_centerVertical="true"
                        android:layout_gravity="center"
                        android:background="@android:color/transparent"
                        android:gravity="center"
                        android:layout_marginLeft="5dp"
                        android:spinnerMode="dropdown" />

                    <ImageView
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_alignParentRight="true"
                        android:layout_centerVertical="true"
                        android:layout_gravity="center"
                        android:src="@mipmap/drop" />

                </RelativeLayout>

Finally looks like below image and it is every where clickable in round area and no need of to write click Lister for imageView.

An error in your httpd.conf or other Apache config files will cause this. Revert httpd.conf et al to the pristine, installer versions and see if Apache runs again.

(I tried Skype and other suggestions here, no luck, but logs [XAMPP > Apache > Logs button] showed that it ran once when first installed. That was the giveaway.)

Likely errors:

• Did you edit with a Windows text editor that changes line endings to non-Unix? (Solution here.)
• Missing or invalid DSO files (.so)

    System.out.println("2.result: " + contains("- to -( \\w+) som", test, 5));
}
static boolean contains(String pattern, String text, Integer fromIndex){
    if(fromIndex != null && fromIndex < text.length())
        return Pattern.compile(pattern).matcher(text).find();

    return Pattern.compile(pattern).matcher(text).find();
}

Just to document my trouble with this issue even though it just appears to be a specific example of other answers; as a relative newbie I feel like this might help others.

Solution:

I added '/usr/bin' to the beginning of PATH for a single session using PATH='/usr/path/:$PATH' and everything started to work fine.

I used gedit to update the PATH permanently, after ensuring it wouldn't break my regular toolchains.

Explanation:

I have multiple toolchains installed on Ubuntu 14.04LTS and I use just a couple on a regular basis. When I tried to use gcc from the command line I got the issue describe by the OP. '/usr/bin' is in the PATH but it is behind the other toolchain locations. Turns out the cc1 for those other toolchains is incompatible with gcc.

The compiler only knows that the code is or isn't reachable if you use "return". Think of Environment.Exit() as a function that you call, and the compiler don't know that it will close the application.

Ensure all dependencies are installed. npm install

I was making a quick app for myself and I had forgotten to add express. Threw the above error.

Take a look at CoffeeScript: http://coffeescript.org

It supports multi-line strings, interpolation, array comprehensions and lots of other nice stuff.

this type of error generally occurs when you have to put characters or values more than that you have specified in Database table like in this case: you specify transaction_status varchar(10) but you actually trying to store
_transaction_status which contain 19 characters. that's why you faced this type of error in this code..

SELECT * FROM items WHERE `items.xml` LIKE '%123456%'

The % operator in LIKE means "anything can be here".

Working example. Notes below.

class Animal {
    constructor(public name) {
    }

    move(meters) {
        alert(this.name + " moved " + meters + "m.");
    }
}

class Snake extends Animal {
    move() {
        alert(this.name + " is Slithering...");
        super.move(5);
    }
}

class Horse extends Animal {
    move() {
        alert(this.name + " is Galloping...");
        super.move(45);
    }
}

var sam = new Snake("Sammy the Python");
var tom: Animal = new Horse("Tommy the Palomino");

sam.move();
tom.move(34);

1. You don't need to manually assign the name to a public variable. Using public name in the constructor definition does this for you.

2. You don't need to call super(name) from the specialised classes.

3. Using this.name works.

Notes on use of super.

This is covered in more detail in section 4.9.2 of the language specification.

The behaviour of the classes inheriting from Animal is not dissimilar to the behaviour in other languages. You need to specify the super keyword in order to avoid confusion between a specialised function and the base class function. For example, if you called move() or this.move() you would be dealing with the specialised Snake or Horse function, so using super.move() explicitly calls the base class function.

There is no confusion of properties, as they are the properties of the instance. There is no difference between super.name and this.name - there is simply this.name. Otherwise you could create a Horse that had different names depending on whether you were in the specialized class or the base class.

why all of this location url?

http://localhost:8080/meet2eat/index.php

you can just use

index.php

if the php files are in the same folder and this is better because if you want to host the files or change the port you will have no problem reaching this URL.

You can use another shell to execute the same command:

Error I get when i execute:

[jenkins@localhost jenkins_data]$ docker exec -it mysqldb \bin\bash
OCI runtime exec failed: exec failed: container_linux.go:345: starting container process caused "exec: \"binsh\": executable file not found in $PATH": unknown

Solution: When I execute it with below command, using bash shell it works:

[jenkins@localhost jenkins_data]$ docker exec -it mysqldb bash
root@<container-ID>:/#

Use insertMany function to insert many documents. This sends only one operation to the server and Mongoose validates all the documents before hitting the mongo server. By default Mongoose inserts item in the order they exist in the array. If you are ok with not maintaining any order then set ordered:false.

Important - Error handling:

When ordered:true validation and error handling happens in a group means if one fails everything will fail.

When ordered:false validation and error handling happens individually and operation will be continued. Error will be reported back in an array of errors.

MySQL does not have internal boolean data type. It uses the smallest integer data type - TINYINT.

The BOOLEAN and BOOL are equivalents of TINYINT(1), because they are synonyms.

Try to create this table -

CREATE TABLE table1 (
  column1 BOOLEAN DEFAULT NULL
);

Then run SHOW CREATE TABLE, you will get this output -

CREATE TABLE `table1` (
  `column1` tinyint(1) DEFAULT NULL
)

Also try System.currentTimeMillis()

Tested on both spark-shell version 1.6.3 and spark2-shell version 2.3.0.2.6.5.179-4, you can directly pipe to the shell's stdin like

spark-shell <<< "1+1"

or in your use case,

spark-shell < file.spark

Another cause of "TCP ACKed Unseen" is the number of packets that may get dropped in a capture. If I run an unfiltered capture for all traffic on a busy interface, I will sometimes see a large number of 'dropped' packets after stopping tshark.

On the last capture I did when I saw this, I had 2893204 packets captured, but once I hit Ctrl-C, I got a 87581 packets dropped message. Thats a 3% loss, so when wireshark opens the capture, its likely to be missing packets and report "unseen" packets.

As I mentioned, I captured a really busy interface with no capture filter, so tshark had to sort all packets, when I use a capture filter to remove some of the noise, I no longer get the error.

PowerShell 3 has the $PSScriptRoot automatic variable:

Contains the directory from which a script is being run.

In Windows PowerShell 2.0, this variable is valid only in script modules (.psm1). Beginning in Windows PowerShell 3.0, it is valid in all scripts.

Don't be fooled by the poor wording. PSScriptRoot is the directory of the current file.

In PowerShell 2, you can calculate the value of $PSScriptRoot yourself:

# PowerShell v2
$PSScriptRoot = Split-Path -Parent -Path $MyInvocation.MyCommand.Definition

To delete folder having files, no need of loops or recursive search. You can directly use:

FileUtils.deleteDirectory(<File object of directory>);

This function will directory delete the folder and all files in it.

This is a simple but effective way to generate incremental filenames. It will look in the current directly (you can easily point that somewhere else) and search for files with the base YourApplicationName*.txt (again you can easily change that). It will start at 0000 so that the first file name will be YourApplicationName0000.txt. if for some reason there are file names with junk between (meaning not numbers) the left and right parts, those files will be ignored by virtue of the tryparse call.

    public static string CreateNewOutPutFile()
    {
        const string RemoveLeft = "YourApplicationName";
        const string RemoveRight = ".txt";
        const string searchString = RemoveLeft + "*" + RemoveRight;
        const string numberSpecifier = "0000";

        int maxTempNdx = -1;

        string fileName;
        string [] Files = Directory.GetFiles(Directory.GetCurrentDirectory(), searchString);
        foreach( string file in Files)
        {
            fileName = Path.GetFileName(file);
            string stripped = fileName.Remove(fileName.Length - RemoveRight.Length, RemoveRight.Length).Remove(0, RemoveLeft.Length);
            if( int.TryParse(stripped,out int current) )
            {
                if (current > maxTempNdx)
                    maxTempNdx = current;
            }
        }
        maxTempNdx++;
        fileName = RemoveLeft + maxTempNdx.ToString(numberSpecifier) + RemoveRight;
        File.CreateText(fileName); // optional
        return fileName;
    }

If you don't need much in the way of custom behavior, JOptionPane is a good time saver. It takes care of the placement and localization of OK / Cancel options, and is a quick-and-dirty way to show a custom dialog without needing to define your own classes. Most of the time the "message" parameter in JOptionPane is a String, but you can pass in a JComponent or array of JComponents as well.

Example:

JTextField firstName = new JTextField();
JTextField lastName = new JTextField();
JPasswordField password = new JPasswordField();
final JComponent[] inputs = new JComponent[] {
        new JLabel("First"),
        firstName,
        new JLabel("Last"),
        lastName,
        new JLabel("Password"),
        password
};
int result = JOptionPane.showConfirmDialog(null, inputs, "My custom dialog", JOptionPane.PLAIN_MESSAGE);
if (result == JOptionPane.OK_OPTION) {
    System.out.println("You entered " +
            firstName.getText() + ", " +
            lastName.getText() + ", " +
            password.getText());
} else {
    System.out.println("User canceled / closed the dialog, result = " + result);
}

Hope this will help you. Assumed that login form has: username and password inputs.

if(isset($_POST['username']) && trim($_POST['username']) != "" && isset($_POST['password']) && trim($_POST['password']) != ""){
//login
} else {
//register
}

You can also create the application.properties file manually.

SpringApplication will load properties from application.properties files in the following locations and add them to the Spring Environment:

• A /config subdirectory of the current directory.
• The current directory
• A classpath /config package
• The classpath root

The list is ordered by precedence (properties defined in locations higher in the list override those defined in lower locations). (From the Spring boot features external configuration doc page)

So just go ahead and create it

The exception message is actually pretty descriptive. The contract it mentions is transitivity: if A > B and B > C then for any A, B and C: A > C. I checked it with paper and pencil and your code seems to have few holes:

if (card1.getRarity() < card2.getRarity()) {
  return 1;

you do not return -1 if card1.getRarity() > card2.getRarity().

if (card1.getId() == card2.getId()) {
  //...
}
return -1;

You return -1 if ids aren't equal. You should return -1 or 1 depending on which id was bigger.

Take a look at this. Apart from being much more readable, I think it should actually work:

if (card1.getSet() > card2.getSet()) {
    return 1;
}
if (card1.getSet() < card2.getSet()) {
    return -1;
};
if (card1.getRarity() < card2.getRarity()) {
    return 1;
}
if (card1.getRarity() > card2.getRarity()) {
    return -1;
}
if (card1.getId() > card2.getId()) {
    return 1;
}
if (card1.getId() < card2.getId()) {
    return -1;
}
return cardType - item.getCardType();  //watch out for overflow!

First of all, your selector is overkill. I suggest using a class or ID selector like my example below. Once you've corrected your selector, simply use jQuery's .each() to iterate through the collection:

ID Selector:

$('#mytable td').each(function() {
    var cellText = $(this).html();    
});

Class Selector:

$('.myTableClass td').each(function() {
    var cellText = $(this).html();    
});

Additional Information:

Take a look at jQuery's selector docs.

Easy solution would be to apply : idxmax() function to get indices of rows with max values. This would filter out all the rows with max value in the group.

In [365]: import pandas as pd

In [366]: df = pd.DataFrame({
'sp' : ['MM1', 'MM1', 'MM1', 'MM2', 'MM2', 'MM2', 'MM4', 'MM4','MM4'],
'mt' : ['S1', 'S1', 'S3', 'S3', 'S4', 'S4', 'S2', 'S2', 'S2'],
'val' : ['a', 'n', 'cb', 'mk', 'bg', 'dgb', 'rd', 'cb', 'uyi'],
'count' : [3,2,5,8,10,1,2,2,7]
})

In [367]: df                                                                                                       
Out[367]: 
   count  mt   sp  val
0      3  S1  MM1    a
1      2  S1  MM1    n
2      5  S3  MM1   cb
3      8  S3  MM2   mk
4     10  S4  MM2   bg
5      1  S4  MM2  dgb
6      2  S2  MM4   rd
7      2  S2  MM4   cb
8      7  S2  MM4  uyi


### Apply idxmax() and use .loc() on dataframe to filter the rows with max values:
In [368]: df.loc[df.groupby(["sp", "mt"])["count"].idxmax()]                                                       
Out[368]: 
   count  mt   sp  val
0      3  S1  MM1    a
2      5  S3  MM1   cb
3      8  S3  MM2   mk
4     10  S4  MM2   bg
8      7  S2  MM4  uyi

### Just to show what values are returned by .idxmax() above:
In [369]: df.groupby(["sp", "mt"])["count"].idxmax().values                                                        
Out[369]: array([0, 2, 3, 4, 8])

Next is used to pass control to the next middleware function. If not the request will be left hanging or open.

Not authoritative, but interesting: 21 is FTP, 23 is telnet. 22 is SSH...something in between (that can take the place of both).

My two cents, adding trim to remove the initial whitespaces left in sAc's answer.

var str = 'Hello, World, etc';
var str_array = str.split(',');

for(var i = 0; i < str_array.length; i++) {
   // Trim the excess whitespace.
   str_array[i] = str_array[i].replace(/^\s*/, "").replace(/\s*$/, "");
   // Add additional code here, such as:
   alert(str_array[i]);
}

Edit:

After getting several upvotes on this answer, I wanted to revisit this. If you want to split on comma, and perform a trim operation, you can do it in one method call without any explicit loops due to the fact that split will also take a regular expression as an argument:

'Hello, cruel , world!'.split(/\s*,\s*/);
//-> ["Hello", "cruel", "world!"]

This solution, however, will not trim the beginning of the first item and the end of the last item which is typically not an issue.

And so to answer the question in regards to process in a loop, if your target browsers support ES5 array extras such as the map or forEach methods, then you could just simply do the following:

myStringWithCommas.split(/\s*,\s*/).forEach(function(myString) {
    console.log(myString);
});

I always prefer to use mixins for small CSS classes like fade in / out incase you want to use them in more than one class.

@mixin fade-in {
    opacity: 1;
    animation-name: fadeInOpacity;
    animation-iteration-count: 1;
    animation-timing-function: ease-in;
    animation-duration: 2s;
}

@keyframes fadeInOpacity {
    0% {
        opacity: 0;
    }
    100% {
        opacity: 1;
    }
}

and if you don't want to use mixins, you can create a normal class .fade-in.

My 2 cents:

$result = $db->query('select * from table limit 1');
$fields = array_keys($result->fetch(PDO::FETCH_ASSOC));

And you will get the column names as an array in the var $fields.

I had the same problem and none of the above answers worked. If you go into the settings (CTRL + ALT + s) and search for project interpreter you will see all of the installed packages. Click the + button at the top right and search for xlrd, then click install package at the bottom left.

I had already done the "pip install xlrd" command from the file location of my python.exe before this, so you may need to do that as well. (you can find the file location by searching it in windows search bar and right click -> open file location, then type cmd into the file explorer address bar)

The --force option will reinstall already installed packages or overwrite already installed files from other packages. You don't want this normally.

If you tell rpm to install all RPMs from some directory, then it does exactly this. rpm will not ignore RPMs listed for installation. You must manually remove the unneeded RPMs from the list (or directory). It will always overwrite the files with the "latest RPM installed" whichever order you do it in.

You can remove the old RPM and rpm will resolve the dependency with the newer version of the installed RPM. But this will only work, if none of the to be installed RPMs depends exactly on the old version.

If you really need different versions of the same RPM, then the RPM must be relocatable. You can then tell rpm to install the specific RPM to a different directory. If the files are not conflicting, then you can just install different versions with rpm -i (zypper in can not install different versions of the same RPM). I am packaging for example ruby gems as relocatable RPMs at work. So I can have different versions of the same gem installed.

I don't know on which files your RPMs are conflicting, but if all of them are "just" man pages, then you probably can simply overwrite the new ones with the old ones with rpm -i --replacefiles. The only problem with this would be, that it could confuse somebody who is reading the old man page and thinks it is for the actual version. Another problem would be the rpm --verify command. It will complain for the new package if the old one has overwritten some files.

Is this possibly a duplicate of https://serverfault.com/questions/522525/rpm-ignore-conflicts?

For iPhone cocoa-touch projects:

I had this problem and thanks to Eric Farraro's comment, I was able to get it resolved. I was importing a class WSHelper.h in many of my other classes. But I also was importing some of those same classes in my WSHelper.h (circular like Eric said). So, to fix this I moved the imports from my WSHelper.h file to my WSHelper.m file as they weren't really needed in the .h file anyway.

I agree with "too much php", try this:

class Grandpa 
{
    public function __construct()
    {
        echo 'Grandpa<br/>';
    }

}

class Papa extends Grandpa
{
    public function __construct()
    {
        echo 'Papa<br/>';
        parent::__construct();
    }
}

class Kiddo extends Papa
{
    public function __construct()
    {
        // THIS IS WHERE I NEED TO CALL GRANDPA'S
        // CONSTRUCTOR AND NOT PAPA'S
        echo 'Kiddo<br/>';
        Grandpa::__construct();
    }
}

$instance = new Kiddo;

I got the result as expected:

Kiddo

Grandpa

This is a feature not a bug, check this for your reference:

https://bugs.php.net/bug.php?id=42016

It is just the way it works. If it sees it is coming from the right context this call version does not enforce a static call.

Instead it will simply keep $this and be happy with it.

parent::method() works in the same way, you don't have to define the method as static but it can be called in the same context. Try this out for more interesting:

class Grandpa 
{
    public function __construct()
    {
        echo 'Grandpa<br/>';
        Kiddo::hello();
    }

}

class Papa extends Grandpa
{
    public function __construct()
    {
        echo 'Papa<br/>';
        parent::__construct();
    }
}

class Kiddo extends Papa
{
    public function __construct()
    {
        // THIS IS WHERE I NEED TO CALL GRANDPA'S
        // CONSTRUCTOR AND NOT PAPA'S
        echo 'Kiddo<br/>';
        Grandpa::__construct();
    }

    public function hello()
    {
        echo 'Hello<br/>';
    }
}

$instance = new Kiddo;

It also works as expected:

Kiddo

Grandpa

Hello

But if you try to initialize a new Papa, you will get an E_STRICT error:

$papa = new Papa;

Strict standards: Non-static method Kiddo::hello() should not be called statically, assuming $this from incompatible context

You can use instanceof to determine if you can call a Children::method() in a parent method:

if ($this instanceof Kiddo) Kiddo::hello();

In swift 3 use:

let url = URL(string: "Whatever url you have(eg: https://google.com)")

Go through following code to convert the DateTime from 12 hrs to 24 hours.

string currentDateString = DateTime.Now.ToString("dd-MMM-yyyy h:mm tt");
DateTime currentDate = Convert.ToDateTime(currentDateString);
Console.WriteLine("String Current Date: " + currentDateString);
Console.WriteLine("Converted Date: " + currentDate.ToString("dd-MMM-yyyy HH:mm"));

Whenever you want the time should be displayed in24 hours use format "HH"

You can refer following link for further details: Custom Date and Time Format Strings

Recently I faced the issue while working on some legacy code. After googling I found that the issue is everywhere but without any concrete resolution. I worked on various parts of the exception message and analyzed below.

Analysis:

1. SSLException: exception happened with the SSL (Secure Socket Layer), which is implemented in javax.net.ssl package of the JDK (openJDK/oracleJDK/AndroidSDK)
2. Read error ssl=# I/O error during system call: Error occured while reading from the Secure socket. It happened while using the native system libraries/driver. Please note that all the platforms solaris, Windows etc. have their own socket libraries which is used by the SSL. Windows uses WINSOCK library.
3. Connection reset by peer: This message is reported by the system library (Solaris reports ECONNRESET, Windows reports WSAECONNRESET), that the socket used in the data transfer is no longer usable because an existing connection was forcibly closed by the remote host. One needs to create a new secure path between the host and client

Reason:

Understanding the issue, I try finding the reason behind the connection reset and I came up with below reasons:

• The peer application on the remote host is suddenly stopped, the host is rebooted, the host or remote network interface is disabled, or the remote host uses a hard close.
• This error may also result if a connection was broken due to keep-alive activity detecting a failure while one or more operations are in progress. Operations that were in progress fail with Network dropped connection on reset(On Windows(WSAENETRESET)) and Subsequent operations fail withConnection reset by peer(On Windows(WSAECONNRESET)).
• If the target server is protected by Firewall, which is true in most of the cases, the Time to live (TTL) or timeout associated with the port forcibly closes the idle connection at given timeout. this is something of our interest

Resolution:

1. Events on the server side such as sudden service stop, rebooted, network interface disabled can not be handled by any means.
2. On the server side, Configure firewall for the given port with the higher Time to Live (TTL) or timeout values such as 3600 secs.
3. Clients can "try" keeping the network active to avoid or reduce the Connection reset by peer.
4. Normally on going network traffic keeps the connection alive and problem/exception is not seen frequently. Strong Wifi has least chances of Connection reset by peer.
5. With the mobile networks 2G, 3G and 4G where the packet data delivery is intermittent and dependent on the mobile network availability, it may not reset the TTL timer on the server side and results into the Connection reset by peer.

Here are the terms suggested to set on various forums to resolve the issue

• ConnectionTimeout: Used only at the time out making the connection. If host takes time to connection higher value of this makes the client wait for the connection.
• SoTimeout: Socket timeout-It says the maximum time within which the a data packet is received to consider the connection as active.If no data received within the given time, the connection is assumed as stalled/broken.
• Linger: Upto what time the socket should not be closed when data is queued to be sent and the close socket function is called on the socket.
• TcpNoDelay: Do you want to disable the buffer that holds and accumulates the TCP packets and send them once a threshold is reached? Setting this to true will skip the TCP buffering so that every request is sent immediately. Slowdowns in the network may be caused by an increase in network traffic due to smaller and more frequent packet transmission.

So none of the above parameter helps keeping the network alive and thus ineffective.

I found one setting that may help resolving the issue which is this functions

setKeepAlive(true)
setSoKeepalive(HttpParams params, enableKeepalive="true") 

How did I resolve my issue?

• Set the HttpConnectionParams.setSoKeepAlive(params, true)
• Catch the SSLException and check for the exception message for Connection reset by peer
• If exception is found, store the download/read progress and create a new connection.
• If possible resume the download/read else restart the download

I hope the details help. Happy Coding...

As people mentioned in the comments you probably don't want to do that... The answer from mipadi is absolutely correct if you know what you're doing.

I would say:

git checkout master
git pull               # to update the state to the latest remote master state
git merge develop      # to bring changes to local master from your develop branch
git push origin master # push current HEAD to remote master branch

Firstly, let's use some semantic HTML.

<nav class="navigation-bar">
    <img class="logo" src="logo.png">
    <ul>
        <li><a href="#">Home</a></li>
        <li><a href="#">Projects</a></li>
        <li><a href="#">About</a></li>
        <li><a href="#">Services</a></li>
        <li><a href="#">Get in Touch</a></li>
    </ul>
</nav>

In fact, you can even get away with the more minimalist:

<nav class="navigation-bar">
    <img class="logo" src="logo.png">
    <a href="#">Home</a>
    <a href="#">Projects</a>
    <a href="#">About</a>
    <a href="#">Services</a>
    <a href="#">Get in Touch</a>
</nav>

Then add some CSS:

.navigation-bar {
    width: 100%;  /* i'm assuming full width */
    height: 80px; /* change it to desired width */
    background-color: red; /* change to desired color */
}
.logo {
    display: inline-block;
    vertical-align: top;
    width: 50px;
    height: 50px;
    margin-right: 20px;
    margin-top: 15px;    /* if you want it vertically middle of the navbar. */
}
.navigation-bar > a {
    display: inline-block;
    vertical-align: top;
    margin-right: 20px;
    height: 80px;        /* if you want it to take the full height of the bar */
    line-height: 80px;    /* if you want it vertically middle of the navbar */
}

Obviously, the actual margins, heights and line-heights etc. depend on your design.

Other options are to use tables or floats for layout, but these are generally frowned upon.

Last but not least, I hope you get cured of div-itis.

this can be solved under MacOS X by installing pyqt with brew

The sklearn.metrics.accuracy_score(y_true, y_pred) method defines y_pred as:

y_pred : 1d array-like, or label indicator array / sparse matrix. Predicted labels, as returned by a classifier.

Which means y_pred has to be an array of 1's or 0's (predicated labels). They should not be probabilities.

The predicated labels (1's and 0's) and/or predicted probabilites can be generated using the LinearRegression() model's methods predict() and predict_proba() respectively.

1. Generate predicted labels:

LR = linear_model.LinearRegression()
y_preds=LR.predict(X_test)
print(y_preds)

output:

[1 1 0 1]

y_preds can now be used for the accuracy_score() method: accuracy_score(y_true, y_pred)

2. Generate probabilities for labels:

Some metrics such as 'precision_recall_curve(y_true, probas_pred)' require probabilities, which can be generated as follows:

LR = linear_model.LinearRegression()
y_preds=LR.predict_proba(X_test)
print(y_preds)

output:

[0.87812372 0.77490434 0.30319547 0.84999743]

float  *n_data = NULL;
int     data_size;
if(data_size = array.Get(n_data))
{     // work with array    }

delete [] n_data;

IntArray   array;
int       *n_data = NULL;
int        data_size;
if(data_size = array.Get(n_data))
{  // work with array  }

delete [] n_data;

Another way to use OVER is to have a result column in your select operate on another "partition", so to say.

This:

SELECT 
    name, 
    ssn, 
    case 
      when ( count(*) over (partition by ssn) ) > 1      
      then 1
      else 0
    end AS hasDuplicateSsn
FROM table;

returns 1 in hasDuplicateSsn for each row whose ssn is shared by another row. Great for making "tags" for data for different error reports and such.

Wikipedia is a decent source for this info.

Since it's a long time and people keep suggesting to use Scanner#nextLine(), there's another chance that Scanner can take spaces included in input.

Class Scanner

A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace.

You can use Scanner#useDelimiter() to change the delimiter of Scanner to another pattern such as a line feed or something else.

Scanner in = new Scanner(System.in);
in.useDelimiter("\n"); // use LF as the delimiter
String question;

System.out.println("Please input question:");
question = in.next();

// TODO do something with your input such as removing spaces...

if (question.equalsIgnoreCase("howdoyoulikeschool?") )
    /* it seems strings do not allow for spaces */
    System.out.println("CLOSED!!");
else
    System.out.println("Que?");

What system are you on? It looks like you have a system with X11, but the DISPLAY environment variable was not properly set. Try executing the following command and then rerunning your program:

export DISPLAY=localhost:0

Its very simple.

Example JSON:

{
   "value":1
}

int z = jsonObject.getInt("value");

The regular expression method should work. However what you can also do is lower case the string from the database, lower case the %variables% you have, and then locate the positions and lengths in the lower cased string from the database. Remember, positions in a string don't change just because its lower cased.

Then using a loop that goes in reverse (its easier, if you do not you will have to keep a running count of where later points move to) remove from your non-lower cased string from the database the %variables% by their position and length and insert the replacement values.

This article might be helpful with changing fonts.

From the article:

The commands to change font attributes are illustrated by the following example:

  \fontencoding{T1}
  \fontfamily{garamond}
  \fontseries{m}
  \fontshape{it}
  \fontsize{12}{15}
  \selectfont

This series of commands set the current font to medium weight italic garamond 12pt type with 15pt leading in the T1 encoding scheme, and the \selectfont command causes LaTeX to look in its mapping scheme for a metric corresponding to these attributes.

You can't do compareAndSet, getAndSet as atomic operation with volatile boolean (unless of course you synchronize it).

The scalar product between (c-a) and (b-a) must be equal to the product of their lengths (this means that the vectors (c-a) and (b-a) are aligned and with the same direction). Moreover, the length of (c-a) must be less than or equal to that of (b-a). Pseudocode:

# epsilon = small constant

def isBetween(a, b, c):
    lengthca2  = (c.x - a.x)*(c.x - a.x) + (c.y - a.y)*(c.y - a.y)
    lengthba2  = (b.x - a.x)*(b.x - a.x) + (b.y - a.y)*(b.y - a.y)
    if lengthca2 > lengthba2: return False
    dotproduct = (c.x - a.x)*(b.x - a.x) + (c.y - a.y)*(b.y - a.y)
    if dotproduct < 0.0: return False
    if abs(dotproduct*dotproduct - lengthca2*lengthba2) > epsilon: return False 
    return True

If you have it available, using curl is your best option.

You can see if it is enabled by doing phpinfo() and searching the page for curl.

If it is enabled, try this:

$curl_handle=curl_init();
curl_setopt($curl_handle, CURLOPT_URL, SITE_PATH . 'cms/data.php');
$xml_file = curl_exec($curl_handle);
curl_close($curl_handle);

put:
If I want to update my first name, then I send a put request:

{ "first": "Nazmul", "last": "hasan" } 

But here is a problem with using put request: When I want to send put request I have to send all two parameters that is first and last (whereas I only need to update first) so it is mandatory to send them all again with put request.

patch:
patch request, on the other hand, says: only specify the data which you need to update and it won't be affecting or changing other data.
So no need to send all values again. Do I only need to change first name? Well, It only suffices to specify first in patch request.

I ran into this issue when trying to get to one of my companies intranet sites. Here is the solution I used:

1. enter about:config into the firefox address bar and agree to continue.
2. search for the preference named security.ssl.enable_ocsp_stapling.
3. double-click this item to change its value to false.

This will lower your security as you will be able to view sites with invalid certs. Firefox will still prompt you that the cert is invalid and you have the choice to proceed forward, so it was worth the risk for me.

Instead of doing all these, one can simply use ".Result" to get the result from a particular task.

eg: List list = GetListAsync().Result;

Which as per the definition => Gets the result value of this Task < TResult >

Basically error saying your are missing "Android SDK Build-tools" installed.

If you are using SQL Server 2012, 2014 or newer, use the Format Function instead:

select Format( decimalColumnName ,'FormatString','en-US' )

Review the Microsoft topic and .NET format syntax for how to define the format string.

An example for this question would be:

select Format( MyDecimalColumn ,'N','en-US' )

Yes, you can!

Is there a method equivalent to getJSONArray in org.json so that I have proper error handling in case it isn't an array?

It depends on your input; i.e. the stuff you fetch from the URL. If the value of the "datasets" attribute is an associative array rather than a plain array, you will get a ClassCastException.

But then again, the correctness of your old version also depends on the input. In the situation where your new version throws a ClassCastException, the old version will throw JSONException. Reference: http://www.json.org/javadoc/org/json/JSONObject.html#getJSONArray(java.lang.String)

You can use std::reverse like this

std::reverse(str.begin(), str.end());

JavaScript calculates right the floor of negative numbers and the remainder of non-integer numbers, following the mathematical definitions for them.

FLOOR is defined as "the largest integer number smaller than the parameter", thus:

• positive numbers: FLOOR(X)=integer part of X;
• negative numbers: FLOOR(X)=integer part of X minus 1 (because it must be SMALLER than the parameter, i.e., more negative!)

REMAINDER is defined as the "left over" of a division (Euclidean arithmetic). When the dividend is not an integer, the quotient is usually also not an integer, i.e., there is no remainder, but if the quotient is forced to be an integer (and that's what happens when someone tries to get the remainder or modulus of a floating-point number), there will be a non-integer "left over", obviously.

JavaScript does calculate everything as expected, so the programmer must be careful to ask the proper questions (and people should be careful to answer what is asked!) Yarin's first question was NOT "what is the integer division of X by Y", but, instead, "the WHOLE number of times a given integer GOES INTO another". For positive numbers, the answer is the same for both, but not for negative numbers, because the integer division (dividend by divisor) will be -1 smaller than the times a number (divisor) "goes into" another (dividend). In other words, FLOOR will return the correct answer for an integer division of a negative number, but Yarin didn't ask that!

gammax answered correctly, that code works as asked by Yarin. On the other hand, Samuel is wrong, he didn't do the maths, I guess, or he would have seen that it does work (also, he didn't say what was the divisor of his example, but I hope it was 3):

Remainder = X % Y = -100 % 3 = -1

GoesInto = (X - Remainder) / Y = (-100 - -1) / 3 = -99 / 3 = -33

By the way, I tested the code on Firefox 27.0.1, it worked as expected, with positive and negative numbers and also with non-integer values, both for dividend and divisor. Example:

-100.34 / 3.57: GoesInto = -28, Remainder = -0.3800000000000079

Yes, I noticed, there is a precision problem there, but I didn't had time to check it (I don't know if it's a problem with Firefox, Windows 7 or with my CPU's FPU). For Yarin's question, though, which only involves integers, the gammax's code works perfectly.

In some cases you can pipe after the command a Out-Null

command | Out-Null

seq -w will detect the max input width and normalize the width of the output.

for num in $(seq -w 01 05); do
    ...
done

At time of writing this didn't work on the newest versions of OSX, so you can either install macports and use its version of seq, or you can set the format explicitly:

seq -f '%02g' 1 3
    01
    02
    03

But given the ugliness of format specifications for such a simple problem, I prefer the solution Henk and Adrian gave, which just uses Bash. Apple can't screw this up since there's no generic "unix" version of Bash:

echo {01..05}

Or:

for number in {01..05}; do ...; done

This gives you the root folder:

System.AppDomain.CurrentDomain.BaseDirectory

You can navigate from here using .. or ./ etc.. , Appending .. takes you to folder where .sln file can be found

For .NET framework (thanks to Adiono comment)

Path.GetFullPath(Path.Combine(AppDomain.CurrentDomain.BaseDirectory,"..\\..\\"))

For .NET core here is a way to do it (thanks to nopara73 comment)

Path.GetFullPath(Path.Combine(AppContext.BaseDirectory, "..\\..\\..\\")) ;

If you are using Hg Tortoise just activate the extension "strip" in:

1. File/Settings/Extensions/
2. Select strip

Then select the bottom revision from where you want to start striping, by doing right click on it, and selecting:

1. Modify history
2. Strip

Just like this:

In this example it will erase from the 19th revision to the last one commited(22).

In short, yes.

Suppose we are on a 32-bit machine.

If it is little endian, the x in the memory will be something like:

       higher memory
          ----->
    +----+----+----+----+
    |0x01|0x00|0x00|0x00|
    +----+----+----+----+
    A
    |
   &x

so (char*)(&x) == 1, and *y+48 == '1'.

If it is big endian, it will be:

    +----+----+----+----+
    |0x00|0x00|0x00|0x01|
    +----+----+----+----+
    A
    |
   &x

so this one will be '0'.

Additional comments to mti2935 good answer.

It seems the higher iteration the better protection against brute force, and you should use a high iteration as you can afford performance/resource wise.

On my my old Intel i3-7100 encrypting a rather big file 1.5GB:

 time openssl enc -aes256 -e -pbkdf2 -iter 10000 -pass pass:"mypassword" -in "InputFile" -out "OutputFile"
 Seconds: 2,564s

 time openssl enc -aes256 -e -pbkdf2 -iter 262144 -pass pass:"mypassword" -in "InputFile" -out "OutputFile"
 Seconds:  2,775s

Not really any difference, didn't check memory usage though(?)

With today's GPUs, and even faster tomorrows, I guess billion brute-force iteration seems possible every seconds.

12 years ago a NVIDIA GeForce 8800 Ultra could iterate over 200.000 millions/sec iterations (MD5 hashing though)

source: Ainane-Barrett-Johnson-Vivar-OpenSSL.pdf

if you know the id of the inputs you only need to use this:

var value = $("#inputID").val();

Apache Commons has an IntegerValidator class which appears to do what you want. Java provides no in-built method for doing this.

See here for the groupid/artifactid.

Maybe not so perfect as above ones, but I guess this is what you were looking for.

data[1:1,3:3]    #works with positive integers
data[1:1, -3:-3] #does not work, gives the entire 1st row without the 3rd element
data[i:i,j:j]    #given that i and j are positive integers

Here indexing will work from 1, i.e,

data[1:1,1:1]    #means the top-leftmost element

You can try something like this. Special Characters range for alphabets starts from 192, so you can avoid such characters in the result.

String name = "A função";

StringBuilder result = new StringBuilder();
for(char val : name.toCharArray()) {
    if(val < 192) result.append(val);
}
System.out.println("Result "+result.toString());

Yes you can do that by just creating a BroadcastReceiver that calls your Service when your Application boots. Here is a complete answer given by me.
Android - Start service on boot

If you don't want any icon/launcher for you Application you can do that also, just don't create any Activity with

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Just declare your Service as declared normally.

Setting my RequestOperationManager Response Serializer to HTTPResponseSerializer fixed the issue.

Objective-C

manager.responseSerializer = [AFHTTPResponseSerializer serializer];

Swift

manager.responseSerializer = AFHTTPResponseSerializer()

Making this change means I don't need to add acceptableContentTypes to every request I make.

So, something like

DECLARE @i AS FLOAT = 2
SELECT @i / 3
SELECT CAST(@i / 3 AS DECIMAL(18,2))

I would however recomend that this be done in the UI/Report layer, as this will cuase loss of precision.

The complete syntax depends on the database engine you're working with:

For SQL Server:

CASE case-expression
    WHEN when-expression-1 THEN value-1
  [ WHEN when-expression-n THEN value-n ... ]
  [ ELSE else-value ]
END

or:

CASE
    WHEN boolean-when-expression-1 THEN value-1
  [ WHEN boolean-when-expression-n THEN value-n ... ]
  [ ELSE else-value ]
END

expressions, etc:

case-expression    - something that produces a value
when-expression-x  - something that is compared against the case-expression
value-1            - the result of the CASE statement if:
                         the when-expression == case-expression
                      OR the boolean-when-expression == TRUE
boolean-when-exp.. - something that produces a TRUE/FALSE answer

Link: CASE (Transact-SQL)

Also note that the ordering of the WHEN statements is important. You can easily write multiple WHEN clauses that overlap, and the first one that matches is used.

Note: If no ELSE clause is specified, and no matching WHEN-condition is found, the value of the CASE expression will be NULL.

this code work fine with IE, Firefox, Opera and Chrome:

$(window).bind('wheel mousewheel', function(event) {
      if (event.originalEvent.deltaY >= 0) {
          console.log('Scroll down');
      }
      else {
          console.log('Scroll up');
      }
  });

'wheel mousewheel' and the property deltaY must be use in bind() function.

Remember : You're user must update their system and browsers for security reasons. In 2018, the excuses of "I have IE 7" is a nonsense. We must educate users.

Have a good day :)

As well as noting the asynchronous nature of setState, be aware that you may have competing event handlers, one doing the state change you want and the other immediately undoing it again. For example onClick on a component whose parent also handles the onClick. Check by adding trace. Prevent this by using e.stopPropagation.

Push annotated tags, keep lightweight local

man git-tag says:

Annotated tags are meant for release while lightweight tags are meant for private or temporary object labels.

And certain behaviors do differentiate between them in ways that this recommendation is useful e.g.:

• annotated tags can contain a message, creator, and date different than the commit they point to. So you could use them to describe a release without making a release commit.

  Lightweight tags don't have that extra information, and don't need it, since you are only going to use it yourself to develop.

• git push --follow-tags will only push annotated tags
• git describe without command line options only sees annotated tags

Internals differences

• both lightweight and annotated tags are a file under .git/refs/tags that contains a SHA-1

• for lightweight tags, the SHA-1 points directly to a commit:

  git tag light
  cat .git/refs/tags/light
  

  prints the same as the HEAD's SHA-1.

  So no wonder they cannot contain any other metadata.

• annotated tags point to a tag object in the object database.

  git tag -as -m msg annot
  cat .git/refs/tags/annot
  

  contains the SHA of the annotated tag object:

  c1d7720e99f9dd1d1c8aee625fd6ce09b3a81fef
  

  and then we can get its content with:

  git cat-file -p c1d7720e99f9dd1d1c8aee625fd6ce09b3a81fef
  

  sample output:

  object 4284c41353e51a07e4ed4192ad2e9eaada9c059f
  type commit
  tag annot
  tagger Ciro Santilli <[email protected]> 1411478848 +0200
  
  msg
  -----BEGIN PGP SIGNATURE-----
  Version: GnuPG v1.4.11 (GNU/Linux)
  
  <YOUR PGP SIGNATURE>
  -----END PGP SIGNAT
  

  And this is how it contains extra metadata. As we can see from the output, the metadata fields are:

  • the object it points to
  • the type of object it points to. Yes, tag objects can point to any other type of object like blobs, not just commits.
  • the name of the tag
  • tagger identity and timestamp
  • message. Note how the PGP signature is just appended to the message

  A more detailed analysis of the format is present at: What is the format of a git tag object and how to calculate its SHA?

Bonuses

• Determine if a tag is annotated:

  git cat-file -t tag
  

  Outputs

  • commit for lightweight, since there is no tag object, it points directly to the commit
  • tag for annotated, since there is a tag object in that case

• List only lightweight tags: How can I list all lightweight tags?

int numberOfDigits(double number){
    if(number < 0){
        number*=-1;
    }
    int i=0;
        while(number > pow(10, i))
            i++;    
    cout << "This number has " << i << " digits" << endl;
    return i;
}

Run yarn cache clean.

jww is right — you're referencing the wrong intermediate certificate.

As you have been issued with a SHA256 certificate, you will need the SHA256 intermediate. You can grab it from here: http://secure2.alphassl.com/cacert/gsalphasha2g2r1.crt

Try the -i flag (or --ignore-errors). The documentation seems to suggest a more robust way to achieve this, by the way:

To ignore errors in a command line, write a - at the beginning of the line's text (after the initial tab). The - is discarded before the command is passed to the shell for execution.

For example,

clean:
  -rm -f *.o

This causes rm to continue even if it is unable to remove a file.

All examples are with rm, but are applicable to any other command you need to ignore errors from (i.e. mkdir).

I found all answers above incomplete somehow, Below are exact steps to get it working.

1. We use npm in order to install the package. For this open the Console and go to your Laravel application directory. Enter the following:

   npm install font-awesome --save-dev

2. Now we have to copy the needed files to the public/css and public/fonts directory. In order to do this open the webpack.mix.js file and add the following:

   mix.copy('node_modules/font-awesome/css/font-awesome.min.css', 'public/css'); mix.copy('node_modules/font-awesome/fonts/*', 'public/fonts');

3. Run the following command in order to execute Laravel Mix:

   npm run dev

4. Add the stylesheet for the Font Awesome in your applications layout file (resources/views/layouts/app.blade.phpapp.blade.php):

   <link href="{{ asset('css/font-awesome.min.css') }}" rel="stylesheet" />

5. Use font awesome icons in templates like

   <i class="fa fa-address-book" aria-hidden="true"></i>

I hope it helps!

You should set the css property touch-action to none as described in this other answer https://stackoverflow.com/a/42288386/1128216

.disable-doubletap-to-zoom {
    touch-action: none;
}

For example => TestController

        [HttpGet]
        public string TestMethod(int arg0)
        {
            return "";
        }

        [HttpGet]
        public string TestMethod2(string arg0)
        {
            return "";
        }

        [HttpGet]
        public string TestMethod3(int arg0,string arg1)
        {
            return "";
        }

If you can only change WebApiConfig.cs file.

 config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{action}/",
                defaults: null
            );

Thats it :)

And Result :

Referring to various articles and doing some trial and error testing, finally I developed this idea which works perfectly for me.

The idea was to detect the unload event that is triggered by closing the browser. In that case, the mouse will be out of the window, pointing out at the close button ('X').

$(window).on('mouseover', (function () {
    window.onbeforeunload = null;
}));
$(window).on('mouseout', (function () {
    window.onbeforeunload = ConfirmLeave;
}));
function ConfirmLeave() {
    return "";
}
var prevKey="";
$(document).keydown(function (e) {            
    if (e.key=="F5") {
        window.onbeforeunload = ConfirmLeave;
    }
    else if (e.key.toUpperCase() == "W" && prevKey == "CONTROL") {                
        window.onbeforeunload = ConfirmLeave;   
    }
    else if (e.key.toUpperCase() == "R" && prevKey == "CONTROL") {
        window.onbeforeunload = ConfirmLeave;
    }
    else if (e.key.toUpperCase() == "F4" && (prevKey == "ALT" || prevKey == "CONTROL")) {
        window.onbeforeunload = ConfirmLeave;
    }
    prevKey = e.key.toUpperCase();
});

The ConfirmLeave function will give the pop up default message, in case there is any need to customize the message, then return the text to be displayed instead of an empty string in function ConfirmLeave().

$.fn.attr(attributeName) returns the attribute value as string, or undefined when the attribute is not present.

Since "", and undefined are both falsy (evaluates to false when coerced to boolean) values in JavaScript, in this case I would write the check as below:

if (wlocation) { ... }

I think you want to specify

-H "Content-Type:text/xml"

with a colon, not an equals.

Don't delete it: for just one commit git cherry-pick is enough.

But if you had several commits on the wrong branch, that is where git rebase --onto shines:

Suppose you have this:

 x--x--x--x <-- master
           \
            -y--y--m--m <- y branch, with commits which should have been on master

, then you can mark master and move it where you would want to be:

 git checkout master
 git branch tmp
 git checkout y
 git branch -f master

 x--x--x--x <-- tmp
           \
            -y--y--m--m <- y branch, master branch

, reset y branch where it should have been:

 git checkout y
 git reset --hard HEAD~2 # ~1 in your case, 
                         # or ~n, n = number of commits to cancel

 x--x--x--x <-- tmp
           \
            -y--y--m--m <- master branch
                ^
                |
                -- y branch

, and finally move your commits (reapply them, making actually new commits)

 git rebase --onto tmp y master
 git branch -D tmp


 x--x--x--x--m'--m' <-- master
           \
            -y--y <- y branch

You don't need to. Just slap it on there as many times as you want and as often as you want. MDN explains identical event listeners:

If multiple identical EventListeners are registered on the same EventTarget with the same parameters, the duplicate instances are discarded. They do not cause the EventListener to be called twice, and they do not need to be removed manually with the removeEventListener method.

In eclipse I included a compressed jar file i.e. zip file. Eclipse allowed me to add this zip file as an external jar but when I tried to access the classes in the jar they weren't showing up.

After a lot of trial and error I found that using a zip format doesn't work. When I added a jar file then it worked for me.

NSDoc save the text file in a string to an html file then simultaneously load it into a webview that is in the same place as your UITextView..

I created a Class in the Models directory called: myData with the following code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.Entity;

namespace Vidly.Models
{
    public class MyDbContext : DbContext
    {
        public MyDbContext()
        {
        }
    }
}

rebuilt the app with: control-shift-b

then ran the following in the nuGet Console:

Enable-Migrations -StartUpProjectName Vidly -ContextTypeName Vidly.Models.MyDbContext -Verbose

the Console returned:

Using StartUp project 'Vidly'. Using NuGet project 'Vidly'. Checking if the context targets an existing database... Code First Migrations enabled for project Vidly. Enable-Migrations -StartUpProjectName Vidly -ContextTypeName Vidly.Models.myData -Verbose

And the FrameWork created a Migrations directory and wrote a Configuration.cs template in there with the following code:

namespace Vidly.Migrations
{
    using System;
    using System.Data.Entity;
    using System.Data.Entity.Migrations;
    using System.Linq;

    internal sealed class Configuration : DbMigrationsConfiguration<Vidly.Models.MyDbContext>
    {
        public Configuration()
        {
            AutomaticMigrationsEnabled = false;
        }

        protected override void Seed(Vidly.Models.MyDbContext context)
        {
            //  This method will be called after migrating to the latest version.

            //  You can use the DbSet<T>.AddOrUpdate() helper extension method 
            //  to avoid creating duplicate seed data.
        }
    }
}

If you add -Wl,--start-group to the linker flags it does not care which order they're in or if there are circular dependencies.

On Qt this means adding:

QMAKE_LFLAGS += -Wl,--start-group

Saves loads of time messing about and it doesn't seem to slow down linking much (which takes far less time than compilation anyway).

I had the same problem. I solve it when I convert string to factor. In your case, check the class of variable and check if they are numeric and 'train and test' should be factor.

Collection<Map<Item, Integer>> itemCollection = basket.values();
Iterator<Map<Item, Integer>> itemIterator =   itemCollection.stream().sorted(new TestComparator()).collect(Collectors.toList()).iterator();



package com.ie.util;

import com.ie.item.Item;

import java.util.Comparator;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;

public class TestComparator implements Comparator<Map<Item, Integer>> {

// comparator is used to sort the Items based on the price


    @Override
    public int compare(Map<Item, Integer> o1, Map<Item, Integer> o2) {


      //  System.out.println("*** compare method will be called *****");


        Item item1 = null;
        Item item2 = null;


        Set<Item> itemSet1 = o1.keySet();
        Iterator<Item> itemIterator1 = itemSet1.iterator();
        if(itemIterator1.hasNext()){
           item1 =   itemIterator1.next();
        }

        Set<Item> itemSet2 = o2.keySet();
        Iterator<Item> itemIterator2 = itemSet2.iterator();
        if(itemIterator2.hasNext()){
            item2 =   itemIterator2.next();
        }


        return -item1.getPrice().compareTo(item2.getPrice());


    }
}

**** this is helpful to sort the nested map objects like Map> here i sorted based on the Item object price .

Yes, this program has likely used less than a millsecond. Try using microsecond resolution with timeval.

e.g:

#include <sys/time.h>

struct timeval stop, start;
gettimeofday(&start, NULL);
//do stuff
gettimeofday(&stop, NULL);
printf("took %lu us\n", (stop.tv_sec - start.tv_sec) * 1000000 + stop.tv_usec - start.tv_usec); 

You can then query the difference (in microseconds) between stop.tv_usec - start.tv_usec. Note that this will only work for subsecond times (as tv_usec will loop). For the general case use a combination of tv_sec and tv_usec.

Edit 2016-08-19

A more appropriate approach on system with clock_gettime support would be:

struct timespec start, end;
clock_gettime(CLOCK_MONOTONIC_RAW, &start);
//do stuff
clock_gettime(CLOCK_MONOTONIC_RAW, &end);

uint64_t delta_us = (end.tv_sec - start.tv_sec) * 1000000 + (end.tv_nsec - start.tv_nsec) / 1000;

iif has always been available in VB, even in VB6.

Dim foo as String = iif(bar = buz, cat, dog)

It is not a true operator, as such, but a function in the Microsoft.VisualBasic namespace.

Wikipedia has a good article on this, and the official spec is here. From Wikipdia:

The local-part of the e-mail address may use any of these ASCII characters:

• Uppercase and lowercase English letters (a-z, A-Z)
• Digits 0 to 9
• Characters ! # $ % & ' * + - / = ? ^ _ ` { | } ~
• Character . (dot, period, full stop) provided that it is not the first or last character, and provided also that it does not appear two or more times consecutively.

Additionally, quoted-strings (ie: "John Doe"@example.com) are permitted, thus allowing characters that would otherwise be prohibited, however they do not appear in common practice. RFC 5321 also warns that "a host that expects to receive mail SHOULD avoid defining mailboxes where the Local-part requires (or uses) the Quoted-string form".

try

var lst= (from char c in source select c.ToString()).ToList();

I don't know which version of Jquery you are using, but this works for me in jquery 1.3:

$.ajax({
    type: 'POST', 
    url: your url,
    data: $('#'+form_id).serialize(), 
    success: function(data) {
        $('#debug').html(data);
  }
});

Then you can access POST array keys as you would normally do in php. Just try with a print_r().

I think you're wrapping serialized form value in an object's property, which is useless as far as i know.

Hope this helps!

Six years on, this is still at the top for some searches. Things have changed a lot since then. Now the defacto standard is more or less to use Volley and the NetworkImageView which takes care of the heavy lifting for you.

Assuming that you already have your Apaters, Loaders and ListFragments setup properly, this official google tutorial explains how to use NetworkImageView to load the images. Images are automatically loaded in a background thread and the view updated on the UI thread. It even supports caching.

Calling p.plot after setting the limits is why it is rescaling. You are correct in that turning autoscaling off will get the right answer, but so will calling xlim() or ylim() after your plot command.

I use this quite a lot to invert the x axis, I work in astronomy and we use a magnitude system which is backwards (ie. brighter stars have a smaller magnitude) so I usually swap the limits with

lims = xlim()
xlim([lims[1], lims[0]]) 

Make sure your oracle services are running automatically. Just press Win+R. Type services.msc in textbox then press O to find oracle services.

In your PC name might be like OracleserviceXYZ. Right click on highlighted services.

In my opinion you should not load and use plugins you don't have to. This particular jQuery plugin doesn't give you anything since directly using the JavaScript sessionStorage object is exactly the same level of complexity. Nor, does the plugin provide some easier way to interact with other jQuery functionality. In addition the practice of using a plugin discourages a deep understanding of how something works. sessionStorage should be used only if its understood. If its understood, then using the jQuery plugin is actually MORE effort.

Consider using sessionStorage directly: https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Storage#sessionStorage

I was using Genymotion 2.9.0. I updated to 3.0.0 Now it is working. So please check Genymotion version.

printf accepts a variable number of arguments. Those can only have Plain Old Data (POD) types. Code that passes anything other than POD to printf only compiles because the compiler assumes you got your format right. %s means that the respective argument is supposed to be a pointer to a char. In your case it is an std::string not const char*. printf does not know it because the argument type goes lost and is supposed to be restored from the format parameter. When turning that std::string argument into const char* the resulting pointer will point to some irrelevant region of memory instead of your desired C string. For that reason your code prints out gibberish.

While printf is an excellent choice for printing out formatted text, (especially if you intend to have padding), it can be dangerous if you haven't enabled compiler warnings. Always enable warnings because then mistakes like this are easily avoidable. There is no reason to use the clumsy std::cout mechanism if the printf family can do the same task in a much faster and prettier way. Just make sure you have enabled all warnings (-Wall -Wextra) and you will be good. In case you use your own custom printf implementation you should declare it with the __attribute__ mechanism that enables the compiler to check the format string against the parameters provided.

C++ solution found here (http://www.cplusplus.com/forum/unices/16430/)

#include <signal.h>
#include <stdio.h>
#include <unistd.h>
void ouch(int sig)
{
    printf("OUCH! - I got signal %d\n", sig);
}
int main()
{
    struct sigaction act;
    act.sa_handler = ouch;
    sigemptyset(&act.sa_mask);
    act.sa_flags = 0;
    sigaction(SIGINT, &act, 0);
    while(1) {
        printf("Hello World!\n");
        sleep(1);
    }
}

//R stands for ROW and C stands for COLUMN:

//i stands for ROW and j stands for COLUMN:

#include<stdio.h>

int main(){

    int M[100][100];

    int R,C,i,j;

    printf("Please enter how many rows you want:\n");

    scanf("%d",& R);

    printf("Please enter how column you want:\n");

    scanf("%d",& C);

    printf("Please enter your matrix:\n");

    for(i = 0; i < R; i++){

        for(j = 0; j < C; j++){

            scanf("%d", &M[i][j]);

        }

        printf("\n");

    }
    for(i = 0; i < R; i++){

        for(j = 0; j < C; j++){

            printf("%d\t", M[i][j]);

        }
        printf("\n");

   }

   getch();

   return 0;
}

If you want to search inside the text, rather than view it, this works:

with unzipped_text as (
  select
    my_id
    ,utl_compress.lz_uncompress(my_compressed_blob) as my_blob
  from my_table
  where my_id='MY_ID'
)
select * from unzipped_text
where dbms_lob.instr(my_blob, utl_raw.cast_to_raw('MY_SEARCH_STRING'))>0;

I had a problem slimier to yours I this quick and its the best solution I have found so far.

What the output looks like

Shows what the output of the code looks like The borders are just to show the spacing and are not needed.

Html:

    <div class="center">
      <ul class="dots">
        <span>
          <li></li>
          <li></li>
          <li></li>
        </span>
      </ul>
    </div>

CSS:

    ul {list-style-type: none;}
    ul li{
        display: inline-block;
        padding: 2px;
        border: 2px solid black;
        border-radius: 5px;}
    .center{
        width: 100%;
        border: 3px solid black;}
    .dots{
        padding: 0px;
        border: 5px solid red;
        text-align: center;}
    span{
        width: 100%;
        border: 5px solid blue;}

Not everything here is needed to center the list items.

You can cut the css down to this to get the same effect:

    ul {list-style-type: none;}
    ul li{display: inline-block;}
    .center{width: 100%;}
    .dots{
        text-align: center;
        padding: 0px;}
    span{width: 100%;}

You need to link with the math library:

gcc -o sphere sphere.c -lm

The error you are seeing: error: ld returned 1 exit status is from the linker ld (part of gcc that combines the object files) because it is unable to find where the function pow is defined.

Including math.h brings in the declaration of the various functions and not their definition. The def is present in the math library libm.a. You need to link your program with this library so that the calls to functions like pow() are resolved.

Still amazed that none recommended the guava library for this.

 //Sample taken from a current working project of mine just to illustrate the idea

    @Override
    public int hashCode(){
        return Objects.hashCode(this.getDate(), this.datePattern);
    }

    @Override
    public boolean equals(Object obj){
        if ( ! obj instanceof DateAndPattern ) {
            return false;
        }
        return Objects.equal(((DateAndPattern)obj).getDate(), this.getDate())
                && Objects.equal(((DateAndPattern)obj).getDate(), this.getDatePattern());
    }

You can use TEXT like this as part of a concatenation

=TEXT(A1,"dd-mmm-yy") & " other string"

If you want to do this via the designer you can do it by following the instructions here "Save changes is not permitted" when changing an existing column to be nullable

Edit:

@t1m0thy's answer is more elegant than mine, better follow his advices.

Also, nice link proposed by @aldemarcalazans in the comments: https://davidwalsh.name/html5-buttons.

Original answer:

Use <a /> when you need a link (the a of anchor). Use <button /> when you need a button.

That said, if you really need to expand an <a />, add the CSS attribute display: block; on it. You'll then be able to specify a width and/or a height (i.e. as if it were a <div />).

Use simplest way of doing this-

SELECT GROUP_CONCAT(Column) from table

<?php
function fWriteFile($sFileName,$sFileContent="No Data",$ROOT)
    {
        $word = new COM("word.application") or die("Unable to instantiate Word");
        //bring it to front
        $word->Visible = 1;
        //open an empty document
        $word->Documents->Add();
        //do some weird stuff
        $word->Selection->TypeText($sFileContent);
        $word->Documents[1]->SaveAs($ROOT."/".$sFileName.".doc");
        //closing word
        $word->Quit();
        //free the object
        $word = null;
        return $sFileName;
    }
?>



<?php
$PATH_ROOT=dirname(__FILE__);
$Return ="<table>";
$Return .="<tr><td>Row[0]</td></tr>";
 $Return .="<tr><td>Row[1]</td></tr>";
$sReturn .="</table>";
fWriteFile("test",$Return,$PATH_ROOT);
?> 

You may use this too

Sub CopyPaste()
Sheet1.Range("A:A").Copy

Sheet2.Activate
col = 1
Do Until Sheet2.Cells(1, col) = ""
    col = col + 1
Loop

Sheet2.Cells(1, col).PasteSpecial xlPasteValues
End Sub

Find your IP address and replace where ever you see 127.0.0.1 with your workstation IP address you get from the link above.

. . .
Require ip your_workstation_IP_address
. . .
Allow from your_workstation_IP_address
. . .
Require ip your_workstation_IP_address
. . .

and in the end don't forget to restart the server

sudo systemctl restart httpd.service

I suggest StackEdit. It is simple WISIWIG editor. You can use both editor and markdown syntax. There is a quick markdown help syntax there. Undo/redo, comments, GoogleDrive, Dropbox interconnection.

I have been doing PHP for my project, and I can say that the following code works for me. You should try it.

echo '<input type = "text" value = '.$idtest.'>'; 

You can do it using the foreach loop

DataTable dr_art_line_2 = ds.Tables["QuantityInIssueUnit"];

  foreach(DataRow row in dr_art_line_2.Rows)
  {
     QuantityInIssueUnit_value = Convert.ToInt32(row["columnname"]);
  }

Angular's $http has a cache built in. According to the docs:

cache – {boolean|Object} – A boolean value or object created with $cacheFactory to enable or disable caching of the HTTP response. See $http Caching for more information.

Boolean value

So you can set cache to true in its options:

$http.get(url, { cache: true}).success(...);

or, if you prefer the config type of call:

$http({ cache: true, url: url, method: 'GET'}).success(...);

Cache Object

You can also use a cache factory:

var cache = $cacheFactory('myCache');

$http.get(url, { cache: cache })

You can implement it yourself using $cacheFactory (especially handly when using $resource):

var cache = $cacheFactory('myCache');

var data = cache.get(someKey);

if (!data) {
   $http.get(url).success(function(result) {
      data = result;
      cache.put(someKey, data);
   });
}

This isn't as easy to do as one might expect -- you can really only do vertical alignment if you know the height of your container. IF this is the case, you can do it with absolute positioning.

The concept is to set the top / left positions at 50%, and then use negative margins (set to half the height / width) to pull the container back to being centered.

Example: http://jsbin.com/ipawe/edit

Basic CSS:

#mydiv { 
    position: absolute;
    top: 50%;
    left: 50%;
    height: 400px;
    width: 700px;
    margin-top: -200px; /* -(1/2 height) */
    margin-left: -350px; /* -(1/2 width) */
  }

To answer my own question, this functionality has been added to pandas in the meantime. Starting from pandas 0.15.0, you can use tz_localize(None) to remove the timezone resulting in local time.
See the whatsnew entry: http://pandas.pydata.org/pandas-docs/stable/whatsnew.html#timezone-handling-improvements

So with my example from above:

In [4]: t = pd.date_range(start="2013-05-18 12:00:00", periods=2, freq='H',
                          tz= "Europe/Brussels")

In [5]: t
Out[5]: DatetimeIndex(['2013-05-18 12:00:00+02:00', '2013-05-18 13:00:00+02:00'],
                       dtype='datetime64[ns, Europe/Brussels]', freq='H')

using tz_localize(None) removes the timezone information resulting in naive local time:

In [6]: t.tz_localize(None)
Out[6]: DatetimeIndex(['2013-05-18 12:00:00', '2013-05-18 13:00:00'], 
                      dtype='datetime64[ns]', freq='H')

Further, you can also use tz_convert(None) to remove the timezone information but converting to UTC, so yielding naive UTC time:

In [7]: t.tz_convert(None)
Out[7]: DatetimeIndex(['2013-05-18 10:00:00', '2013-05-18 11:00:00'], 
                      dtype='datetime64[ns]', freq='H')

This is much more performant than the datetime.replace solution:

In [31]: t = pd.date_range(start="2013-05-18 12:00:00", periods=10000, freq='H',
                           tz="Europe/Brussels")

In [32]: %timeit t.tz_localize(None)
1000 loops, best of 3: 233 µs per loop

In [33]: %timeit pd.DatetimeIndex([i.replace(tzinfo=None) for i in t])
10 loops, best of 3: 99.7 ms per loop

Bear in mind that it is only worth using anything other than a full table scan to find these values if the number of blocks that contain a row that matches the predicate is significantly smaller than the total number of blocks in the table. That is why Oracle will often decline the use of an index in order to full scan when you use LIKE '%x%' where x is a very small string. For example if the optimizer believes that using an index would still require single-block reads on (say) 20% of the table blocks then a full table scan is probably a better option than an index scan.

Sometimes you know that your predicate is much more selective than the optimizer can estimate. In such a case you can look into supplying an optimizer hint to perform an index fast full scan on the relevant column (particularly if the index is a much smaller segment than the table).

SELECT /*+ index_ffs(users (users.last_name)) */
       * 
FROM   users
WHERE  last_name LIKE "%z%"

This library helped me, I had a dict list of nested keys with the same name but with different values, every other solution kept overriding those nested keys.

https://pypi.org/project/deepmerge/

from deepmerge import always_merger

def process_parms(args):
    temp_list = []
    for x in args:
        with open(x, 'r') as stream:
            temp_list.append(yaml.safe_load(stream))

    return always_merger.merge(*temp_list)

The short answer to that is no. While you can enter multiple tables in the from clause of an update statement, you can only specify a single table after the update keyword. Even if you do write a "updatable" view (which is simply a view that follows certain restrictions), updates like this will fail. Here are the relevant clips from the MSDN documentation (emphasis is mine).

UPDATE (Transact-SQL)

The view referenced by table_or_view_name must be updatable and reference exactly one base table in the FROM clause of the view. For more information about updatable views, see CREATE VIEW (Transact-SQL).

CREATE VIEW (Transact-SQL)

You can modify the data of an underlying base table through a view, as long as the following conditions are true:

• Any modifications, including UPDATE, INSERT, and DELETE statements, must reference columns from only one base table.
• The columns being modified in the view must directly reference the underlying data in the table columns. The columns cannot be derived in any other way, such as through the following:
  • An aggregate function: AVG, COUNT, SUM, MIN, MAX, GROUPING, STDEV, STDEVP, VAR, and VARP.
  • A computation. The column cannot be computed from an expression that uses other columns. Columns that are formed by using the set operators UNION, UNION ALL, CROSSJOIN, EXCEPT, and INTERSECT amount to a computation and are also not updatable.
• The columns being modified are not affected by GROUP BY, HAVING, or DISTINCT clauses.
• TOP is not used anywhere in the select_statement of the view together with the WITH CHECK OPTION clause.

In all honesty, though, you should consider using two different SQL statements within a transaction as per LBushkin's example.

UPDATE: My original assertion that you could update multiple tables in an updatable view was wrong. On SQL Server 2005 & 2012, it will generate the following error. I have corrected my answer to reflect this.

Msg 4405, Level 16, State 1, Line 1

View or function 'updatable_view' is not updatable because the modification affects multiple base tables.

I think the best solution to solve the issue is to use reactive extensions When you transform event into observable, then you can just add Throttling(..) (originally called Debounce(..))

Sample code here

        var templatesWatcher = new FileSystemWatcher(settingsSnapshot.Value.TemplatesDirectory)
        {
            NotifyFilter = NotifyFilters.LastWrite,
            IncludeSubdirectories = true
        };

        templatesWatcher.EnableRaisingEvents = true;

        Observable.FromEventPattern<FileSystemEventHandler, FileSystemEventArgs>(
                addHandler => templatesWatcher.Changed += addHandler,
                removeHandler => templatesWatcher.Changed -= removeHandler)
            .Throttle(TimeSpan.FromSeconds(5))
            .Subscribe(args =>
            {
                _logger.LogInformation($"Template file {args.EventArgs.Name} has changed");
                //TODO do something
            });

$(".price").each(function(){ 
total_price += parseFloat($(this).val()); 
}); 

please try like this...

Absolutely. You can use the LINQ Dynamic Query Library, found on Scott Guthrie's blog. There's also an updated version available on CodePlex.

It lets you create OrderBy clauses, Where clauses, and just about everything else by passing in string parameters. It works great for creating generic code for sorting/filtering grids, etc.

var result = data
    .Where(/* ... */)
    .Select(/* ... */)
    .OrderBy("Foo asc");

var query = DbContext.Data
    .Where(/* ... */)
    .Select(/* ... */)
    .OrderBy("Foo ascending");

A back link is a link that moves the browser backwards one page, as if the user had clicked the Back button available in most browsers. Back links use JavaScript. It moves the browser back one page if your browser supports JavaScript (which it does) and if it supports the window.history object, which is necessary for back links.

Simple ways are

<a href="#" onClick="history.go(-1)">Go Back</a>

OR:

function goBack() {_x000D_
  window.history.back()_x000D_
}

<a href="#" onclick="goBack()" />Go Back</a>

Generally speaking a back link isn't necessary… the Back button usually suffices quite nicely, and usually you can also simply link to the previous page in your site. However, sometimes you might want to provide a link back to one of several "previous" pages, and that's where a back link comes in handy. So I refer you below tutorial if you want to do in more advanced way:

Run jupyter kernelspec list to get the paths of all your kernels.
Then simply uninstall your unwanted-kernel

jupyter kernelspec uninstall unwanted-kernel

Old answer
Delete the folder corresponding to the kernel you want to remove.

The docs has a list of the common paths for kernels to be stored in: http://jupyter-client.readthedocs.io/en/latest/kernels.html#kernelspecs

Well there's no difference between the first two - they're just using different names for the type parameter (E or T).

The third isn't a valid declaration - ? is used as a wildcard which is used when providing a type argument, e.g. List<?> foo = ... means that foo refers to a list of some type, but we don't know what.

All of this is generics, which is a pretty huge topic. You may wish to learn about it through the following resources, although there are more available of course:

• Java Tutorial on Generics
• Language guide to generics
• Generics in the Java programming language
• Angelika Langer's Java Generics FAQ (massive and comprehensive; more for reference though)

If you're using dom4j, you can just do:

Document document = DocumentHelper.parseText(text);

//then str[0] will return 'T' not "T"

The methods in some of the other answers that use a regular expression do not cover all cases, particularly:

1. When the cookie is the last cookie. In this case there will not be a semicolon after the cookie value.
2. When another cookie name ends with the name being looked up. For example, you are looking for the cookie named "one", and there is a cookie named "done".
3. When the cookie name includes characters that are not interpreted as themselves when used in a regular expression unless they are preceded by a backslash.

The following method handles these cases:

function getCookie(name) {
    function escape(s) { return s.replace(/([.*+?\^$(){}|\[\]\/\\])/g, '\\$1'); }
    var match = document.cookie.match(RegExp('(?:^|;\\s*)' + escape(name) + '=([^;]*)'));
    return match ? match[1] : null;
}

This will return null if the cookie is not found. It will return an empty string if the value of the cookie is empty.

Notes:

1. This function assumes cookie names are case sensitive.
2. document.cookie - When this appears on the right-hand side of an assignment, it represents a string containing a semicolon-separated list of cookies, which in turn are name=value pairs. There appears to be a single space after each semicolon.
3. String.prototype.match() - Returns null when no match is found. Returns an array when a match is found, and the element at index [1] is the value of the first matching group.

Regular Expression Notes:

1. (?:xxxx) - forms a non-matching group.
2. ^ - matches the start of the string.
3. | - separates alternative patterns for the group.
4. ;\\s* - matches one semi-colon followed by zero or more whitespace characters.
5. = - matches one equal sign.
6. (xxxx) - forms a matching group.
7. [^;]* - matches zero or more characters other than a semi-colon. This means it will match characters up to, but not including, a semi-colon or to the end of the string.

I didn't find find the correct jsonpath filter syntax to extract a value from a name-value pair in json.

Here's the syntax and an abbreviated sample twitter document below.

This site was useful for testing:

The jsonpath filter expression:

.events[0].attributes[?(@.name=='screen_name')].value

Test document:

{
  "title" : "test twitter",
  "priority" : 5,
  "events" : [ {
    "eventId" : "150d3939-1bc4-4bcb-8f88-6153053a2c3e",
    "eventDate" : "2015-03-27T09:07:48-0500",
    "publisher" : "twitter",
    "type" : "tweet",
    "attributes" : [ {
      "name" : "filter_level",
      "value" : "low"
    }, {
      "name" : "screen_name",
      "value" : "_ziadin"
    }, {
      "name" : "followers_count",
      "value" : "406"
    } ]
  } ]
}

For React.js, you can do this with more readable code. Hope it helps.

handleCheckboxChange(e) {
  console.log('value of checkbox : ', e.target.checked);
}
render() {
  return <input type="checkbox" onChange={this.handleCheckboxChange.bind(this)} />
}

First, add the Material Design dependency.

implementation 'com.google.android.material:material:<version>'

To get the latest material design library version. check the official website github repository.

Current version is 1.2.0.

So, you have to add,

implementation 'com.google.android.material:material:1.2.0'

Then, you need to change the app theme to material theme by adding,

<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

in your style.xml. Dont forget to set the same theme in your application theme in your manifest file.

You could use java.time.temporal.ValueRange which accepts long and would also work with int:

int a = 2147;

//Use java 8 java.time.temporal.ValueRange. The range defined
//is inclusive of both min and max 
ValueRange range = ValueRange.of(0, 2147483647);

if(range.isValidValue(a)) {
    System.out.println("in range");
}else {
    System.out.println("not in range");
}

UPDATE: for rxjs > v5.5

As mentioned in some of the comments and other answers, by default the HttpClient deserializes the content of a response into an object. Some of its methods allow passing a generic type argument in order to duck-type the result. Thats why there is no json() method anymore.

import {throwError} from 'rxjs';
import {catchError, map} from 'rxjs/operators';

export interface Order {
  // Properties
}

interface ResponseOrders {
  results: Order[];
}

} 

Notice that you could easily transform the returned Observable to a Promise by simply invoking toPromise().

ORIGINAL ANSWER:

In your case, you can

Assumming that your backend returns something like:

{results: [{},{}]}

in JSON format, where every {} is a serialized object, you would need the following:

// Somewhere in your src folder

export interface Order {
  // Properties
}

import { HttpClient, HttpParams } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/map';

import { Order } from 'somewhere_in_src';    

@Injectable()
export class FooService {
 ctor(private http: HttpClient){}

 fetch(startIndex: number, limit: number): Observable<Order[]> {
    let params = new HttpParams();
    params = params.set('startIndex',startIndex.toString()).set('limit',limit.toString());
    // base URL should not have ? in it at the en
    return this.http.get(this.baseUrl,{
       params
    })
    .map(res => res.results as Order[] || []); 
   // in case that the property results in the res POJO doesnt exist (res.results returns null) then return empty array ([])
  }
} 

I removed the catch section, as this could be archived through a HTTP interceptor. Check the docs. As example:

https://gist.github.com/jotatoledo/765c7f6d8a755613cafca97e83313b90

And to consume you just need to call it like:

// In some component for example
this.fooService.fetch(...).subscribe(data => ...); // data is Order[]

The best way is,

var first = '2012-11-21';
var second = '2012-11-03';

if (new Date(first) > new Date(second) {
    .....
}

If you know that your input will be either "True" or "False" then why not use:

def bool_convert(s):
    return s == "True"

Somewhere you have to keep track of what button had been pressed. When things happen, you need to store something in a variable so you can recall the information or it's gone forever.

When someone pressed one of the operator buttons, don't just let them type in another value. Save the operator symbol, then let them type in another value. You could literally just have a String operator that gets the text of the operator button pressed. Then, when the equals button is pressed, you have to check to see which operator you stored. You could do this with an if/else if/else chain.

So, in your symbol's button press event, store the symbol text in a variable, then, in the = button press event, check to see which symbol is in the variable and act accordingly.

Alternatively, if you feel comfortable enough with enums (looks like you're just starting, so if you're not to that point yet, ignore this), you could have an enumeration of symbols that lets you check symbols easily with a switch.

Like this:

#include <string>
#include <vector>

struct user
{
    std::string username;
    std::vector<unsigned char> userpassword;
};

int main()
{
    user r;   // r.username is "" and r.userpassword is empty
    // ...
}

I started out naming enums in the plural but have since changed to singular. Just seems to make more sense in the context of where they're used.

enum Status { Unknown = 0, Incomplete, Ready }

Status myStatus = Status.Ready;

Compare to:

Statuses myStatus = Statuses.Ready;

I find the singular form to sound more natural in context. We are in agreement that when declaring the enum, which happens in one place, we're thinking "this is a group of whatevers", but when using it, presumably in many places, that we're thinking "this is one whatever".

graphics.h appears to something once bundled with Borland and/or Turbo C++, in the 90's.

http://www.daniweb.com/software-development/cpp/threads/17709/88149#post88149

It's unlikely that you will find any support for that file with modern compiler. For other graphics libraries check the list of "related" questions (questions related to this one). E.g., "A Simple, 2d cross-platform graphics library for c or c++?".

Usually the desire is to match the menu width to the width of the dropdown parent. This can be achieved easily like so:

.dropdown-menu {
  width:100%;
}

In case, if you want to do some job on the selection of one of the radio buttons (without having any additional OK button or something), your code is fine, updated little.

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        RadioGroup rg = (RadioGroup) findViewById(R.id.radioGroup1);

        rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() 
        {
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                switch(checkedId){
                    case R.id.radio0:
                        // do operations specific to this selection
                        break;
                    case R.id.radio1:
                        // do operations specific to this selection
                        break;
                    case R.id.radio2:
                        // do operations specific to this selection
                        break;
                }   
            }
        });
    }
}

A lot of *NIX systems also have either or both pkill(1) and killall(1) which, allows you to kill processes by name. Using them, you can avoid the whole parsing ps problem.

I found the solution here:

How to properly -filter multiple strings in a PowerShell copy script

You have to use -Include flag for Get-ChildItem

My Example:

$Location = "C:\user\files" 
$result = (Get-ChildItem $Location\* -Include *.png, *.gif, *.jpg)

Dont forget put "*" after path location.

The only solution that worked for me (node 12.x, npm 6.x) was using npm-force-resolutions developed by @Rogerio Chaves.

First, install it by:

npm install npm-force-resolutions --save-dev

You can add --ignore-scripts if some broken transitive dependency scripts are blocking you from installing anything.

Then in package.json define what dependency should be overridden (you must set exact version number):

"resolutions": {
  "your-dependency-name": "1.23.4"
}

and in "scripts" section add new preinstall entry:

"preinstall": "npx npm-force-resolutions",

Now, npm install will apply changes and force your-dependency-name to be at version 1.23.4 for all dependencies.

The answers above me works. But, I'd like to contribute a method on how to perform it using GET

on your html/php page

$File = 'some/dir/file.jpg';
<a href="<?php echo '../sumdir/download.php?f='.$File; ?>" target="_blank">Download</a>

and download.php contains

$file = $_GET['f']; 

header("Expires: 0");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");

$ext = pathinfo($file, PATHINFO_EXTENSION);
$basename = pathinfo($file, PATHINFO_BASENAME);

header("Content-type: application/".$ext);
header('Content-length: '.filesize($file));
header("Content-Disposition: attachment; filename=\"$basename\"");
ob_clean(); 
flush();
readfile($file);
exit;

this should work on any file types. this is not tested using POST, but it could work.

For ssh style urls just add ssh before the url:

yarn add ssh://<whatever>@<xxx>#<branch,tag,commit>

A generic,simpler and a bit primitive approach to find tag, attribute and value

    Pattern pattern = Pattern.compile("<(\\w+)( +.+)*>((.*))</\\1>");
    System.out.println(pattern.matcher("<asd> TEST</asd>").find());
    System.out.println(pattern.matcher("<asd TEST</asd>").find());
    System.out.println(pattern.matcher("<asd attr='3'> TEST</asd>").find());
    System.out.println(pattern.matcher("<asd> <x>TEST<x>asd>").find());
    System.out.println("-------");
    Matcher matcher = pattern.matcher("<as x> TEST</as>");
    if (matcher.find()) {
        for (int i = 0; i <= matcher.groupCount(); i++) {
            System.out.println(i + ":" + matcher.group(i));
        }
    }

Here a code that works with windows office 2010. This script will ask you for input filtered range of cells and then the paste range.

Please, both ranges should have the same number of cells.

Sub Copy_Filtered_Cells()

Dim from As Variant
Dim too As Variant
Dim thing As Variant
Dim cell As Range

'Selection.SpecialCells(xlCellTypeVisible).Select

    'Set from = Selection.SpecialCells(xlCellTypeVisible)
    Set temp = Application.InputBox("Copy Range :", Type:=8)
    Set from = temp.SpecialCells(xlCellTypeVisible)
    Set too = Application.InputBox("Select Paste range selected cells ( Visible cells only)", Type:=8)



    For Each cell In from
        cell.Copy
        For Each thing In too
            If thing.EntireRow.RowHeight > 0 Then
                thing.PasteSpecial
                Set too = thing.Offset(1).Resize(too.Rows.Count)
                Exit For
            End If
        Next
    Next


End Sub

Enjoy!

I like this one depending of purpose

window.location.href.split("/")[2] == "localhost:17000" //always domain + port

You can apply it on any url-string

var url = "http://localhost:17000/sub1/sub2/mypage.html?q=12";
url.split("/")[2] == "localhost:17000"
url.split("/")[url.split("/").length-1] == "mypage.html?q=12"

Removing protocol, domain & path from url-string (relative path)

var arr = url.split("/");
if (arr.length>3)
   "/" + arr.splice(3, arr.length).join("/") == "/sub1/sub2/mypage.html?q=12"

Update

Inspired by Daniel's code above and the fact that this is WAY! more interesting to me now then the actual work I have to do, i created a hopefully full-proof function to find the first blank row in a sheet. Improvements welcome! Otherwise, this is going to my library :) Hopefully others benefit as well.

    Function firstBlankRow(ws As Worksheet) As Long
'returns the row # of the row after the last used row
'Or the first row with no data in it

    Dim rngSearch As Range, cel As Range

    With ws

        Set rngSearch = .UsedRange.Columns(1).Find("") '-> does blank exist in the first column of usedRange

        If Not rngSearch Is Nothing Then

            Set rngSearch = .UsedRange.Columns(1).SpecialCells(xlCellTypeBlanks)

            For Each cel In rngSearch

                If Application.WorksheetFunction.CountA(cel.EntireRow) = 0 Then

                    firstBlankRow = cel.Row
                    Exit For

                End If

            Next

        Else '-> no blanks in first column of used range

            If Application.WorksheetFunction.CountA(Cells(.Rows.Count, 1).EntireRow) = 0 Then '-> is the last row of the sheet blank?

                '-> yeap!, then no blank rows!
                MsgBox "Whoa! All rows in sheet are used. No blank rows exist!"


            Else

                '-> okay, blank row exists
                firstBlankRow = .UsedRange.SpecialCells(xlCellTypeBlanks).Row + 1

            End If

        End If

    End With

End Function

Original Answer

To find the first blank in a sheet, replace this part of your code:

Cells(1, 1).Select
For Each Cell In ws.UsedRange.Cells
    If Cell.Value = "" Then Cell = Num
    MsgBox "Checking cell " & Cell & " for value."
Next

With this code:

With ws

    Dim rngBlanks As Range, cel As Range

    Set rngBlanks = Intersect(.UsedRange, .Columns(1)).Find("")

    If Not rngBlanks Is Nothing Then '-> make sure blank cell exists in first column of usedrange
        '-> find all blank rows in column A within the used range
        Set rngBlanks = Intersect(.UsedRange, .Columns(1)).SpecialCells(xlCellTypeBlanks)

        For Each cel In rngBlanks '-> loop through blanks in column A

            '-> do a countA on the entire row, if it's 0, there is nothing in the row
            If Application.WorksheetFunction.CountA(cel.EntireRow) = 0 Then
                num = cel.Row
                Exit For
            End If

        Next
    Else

        num = usedRange.SpecialCells(xlCellTypeLastCell).Offset(1).Row                 

    End If


End With

In terms of pattern interpretation, there's no difference between the following forms:

• /pattern/
• new RegExp("pattern")

If you want to replace a literal string using the replace method, I think you can just pass a string instead of a regexp to replace.

Otherwise, you'd have to escape any regexp special characters in the pattern first - maybe like so:

function reEscape(s) {
    return s.replace(/([.*+?^$|(){}\[\]])/mg, "\\$1");
}

// ...

var re = new RegExp(reEscape(pattern), "mg");
this.markup = this.markup.replace(re, value);

• stop the HTC Sync (in system tray)

• rename HTC's adb.exe which I found at that path:

   C:\Program Files (x86)\HTC\HTC Sync 3.0\adb.exe.
  

This is really simple, the String object has an endsWith method.

From your question it seems like you want either /, , or . as the delimiter set.

So:

String str = "This.is.a.great.place.to.work.";

if (str.endsWith(".work.") || str.endsWith("/work/") || str.endsWith(",work,"))
     // ... 

You can also do this with the matches method and a fairly simple regex:

if (str.matches(".*([.,/])work\\1$"))

Using the character class [.,/] specifying either a period, a slash, or a comma, and a backreference, \1 that matches whichever of the alternates were found, if any.

If you want to print/write double value at console then use System.out.printf() or System.out.format() methods.

System.out.printf("\n$%10.2f",shippingCost);
System.out.printf("%n$%.2f",shippingCost);

Use grep -n to get the line number of a match.

I don't think there's a way to get grep to start on a certain line number. For that, use sed. For example, to start at line 10 and print the line number and line for matching lines, use:

sed -n '10,$ { /regex/ { =; p; } }' file

To get only the line numbers, you could use

grep -n 'regex' | sed 's/^\([0-9]\+\):.*$/\1/'

Or you could simply use sed:

sed -n '/regex/=' file

Combining the two sed commands, you get:

sed -n '10,$ { /regex/= }' file

You must set the image rendering mode to UIImageRenderingModeAlwaysTemplate in order to have the tintColor affect the UIImage. Here is the solution in Swift:

let image = UIImage(named: "image-name")
let button = UIButton()
button.setImage(image?.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate), forState: .Normal)
button.tintColor = UIColor.whiteColor()

SWIFT 4x

button.setImage(image.withRenderingMode(UIImage.RenderingMode.alwaysTemplate), for: .normal)
button.tintColor = UIColor.blue
