The ideal answer found in the forum mentioned above is this:

sed -i 's/facebook-android-sdk:4.+/facebook-android-sdk:4.22.1/g' ./node_modules/react-native-fbsdk/android/build.gradle

This works

try this

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

Here is an example:

Process.Start("CMD", "/C Pause")


/C  Carries out the command specified by string and then terminates
/K  Carries out the command specified by string but remains

And here is a extended function: (Notice the comment-lines using CMD commands.)

Forget switch and break, lets play with if. And instead of asserting

if(pageid === "listing-page" || pageid === "home-page")

lets create several arrays with cases and check it with Array.prototype.includes()

var caseA = ["listing-page", "home-page"];
var caseB = ["details-page", "case04", "case05"];

if(caseA.includes(pageid)) {
    alert("hello");
}
else if (caseB.includes(pageid)) {
    alert("goodbye");
}
else {
    alert("there is no else case");
}

I surprise no one had mentioned this possible easy approach in visual studio code.

Install VS Code and Apache maven ( just as mentioned by @Steve Chambers)

After installing this extension vscode:extension/vscjava.vscode-java-pack

In the java overview page , there is a an option which reads 'Create Maven Project' which further takes to a simple wizard to generate maven project.

Its pretty quick which is intutitive enough, even newbies can very well start with a Maven project.

To spool from a BEGIN END block is pretty simple. For example if you need to spool result from two tables into a file, then just use the for loop. Sample code is given below.

BEGIN

FOR x IN 
(
    SELECT COLUMN1,COLUMN2 FROM TABLE1
    UNION ALL
    SELECT COLUMN1,COLUMN2 FROM TABLEB
)    
LOOP
    dbms_output.put_line(x.COLUMN1 || '|' || x.COLUMN2);
END LOOP;

END;
/

Try this:

.slideContainer {_x000D_
    overflow-x: scroll;_x000D_
    white-space: nowrap;_x000D_
}_x000D_
.slide {_x000D_
    display: inline-block;_x000D_
    width: 600px;_x000D_
    white-space: normal;_x000D_
}

<div class="slideContainer">_x000D_
    <span class="slide">Some content</span>_x000D_
    <span class="slide">More content. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</span>_x000D_
    <span class="slide">Even more content!</span>_x000D_
</div>

Note that you can omit .slideContainer { overflow-x: scroll; } (which browsers may or may not support when you read this), and you'll get a scrollbar on the window instead of on this container.

The key here is display: inline-block. This has decent cross-browser support nowadays, but as usual, it's worth testing in all target browsers to be sure.

There are a million duplicates of this question on here, but here goes again anyway:

document.onkeypress = function(evt) {
    evt = evt || window.event;
    var charCode = evt.keyCode || evt.which;
    var charStr = String.fromCharCode(charCode);
    alert(charStr);
};

The best reference on key events I've seen is http://unixpapa.com/js/key.html.

The lack of a Linux-like backtick/backquote facility is a major annoyance of the pre-PowerShell world. Using backquotes via for-loops is not at all cosy. So we need kinda of setvar myvar cmd-line command.

In my %path% I have a dir with a number of bins and batches to cope with those Win shortcomings.

One batch I wrote is:

:: setvar varname cmd
:: Set VARNAME to the output of CMD
:: Triple escape pipes, eg:
:: setvar x  dir c:\ ^^^| sort 
:: -----------------------------

@echo off
SETLOCAL

:: Get command from argument 
for /F "tokens=1,*" %%a in ("%*") do set cmd=%%b

:: Get output and set var
for /F "usebackq delims=" %%a in (`%cmd%`) do (
     ENDLOCAL
     set %1=%%a
)

:: Show results 
SETLOCAL EnableDelayedExpansion
echo %1=!%1! 

So in your case, you would type:

> setvar text echo Hello
text=Hello 

The script informs you of the results, which means you can:

> echo text var is now %text%
text var is now Hello 

You can use whatever command:

> setvar text FIND "Jones" names.txt

What if the command you want to pipe to some variable contains itself a pipe?
Triple escape it, ^^^|:

> setvar text dir c:\ ^^^| find "Win"

You could set the path to a constant like this and set it using express.

const viewsPath = path.join(__dirname, '../views') 
app.set('view engine','hbs')

 app.set('views', viewsPath)

 app.get('/', function(req, res){

 res.render("index");

});

This worked for me

in the search window type 'environment variables' this should give you a link to editing the variables. On the variables editing page there is an upper section and a lower section in the lower section add NEW,type path C:\Program Files\Java\jdk-10\bin this worked great for me and it finds the compiler all the time.

That message is usually an indication that some of your files have modification times later than the current system time. Since make decides which files to compile when performing an incremental build by checking if a source files has been modified more recently than its object file, this situation can cause unnecessary files to be built, or worse, necessary files to not be built.

However, if you are building from scratch (not doing an incremental build) you can likely ignore this warning without consequence.

We can use rename_with to rename columns with a function (stringr functions, for example).

Consider the following data df_1:

df_1 <- data.frame(
  x = replicate(n = 3, expr = rnorm(n = 3, mean = 10, sd = 1)), 
  y = sample(x = 1:2, size = 10, replace = TRUE)
)

names(df_1)

#[1] "x.1" "x.2" "x.3" "y" 

Rename all variables with dplyr::everything():

library(tidyverse)

df_1 %>% 
  rename_with(.data = ., .cols = everything(.), 
              .fn = str_replace, pattern = '.*', 
              replacement = str_c('var', seq_along(.), sep = '_')) %>% 
  names()

#[1] "var_1" "var_2" "var_3" "var_4"

Rename by name particle with some dplyr verbs (starts_with, ends_with, contains, matches, ...).

Example with . (x variables):

df_1 %>% 
  rename_with(.data = ., .cols = contains('.'), 
              .fn = str_replace, pattern = '.*', 
              replacement = str_c('var', seq_along(.), sep = '_')) %>% 
  names()

#[1] "var_1" "var_2" "var_3" "y"

Rename by class with many functions of class test, like is.integer, is.numeric, is.factor...

Example with is.integer (y):

df_1 %>% 
  rename_with(.data = ., .cols = is.integer, 
              .fn = str_replace, pattern = '.*', 
              replacement = str_c('var', seq_along(.), sep = '_')) %>% 
  names()

#[1] "x.1"   "x.2"   "x.3"   "var_1"

The warning:

Warning messages: 1: In stri_replace_first_regex(string, pattern, fix_replacement(replacement), : longer object length is not a multiple of shorter object length 2: In names[cols] <- .fn(names[cols], ...) : number of items to replace is not a multiple of replacement length

It is not relevant, as it is just an inconsistency of seq_along(.) with the replace function.

_{I guess many people are entering in this question looking for a way to avoid the new line in awk. Thus, I am going to offer a solution to just that, since the answer to the specific context was already solved!}

In awk, print automatically inserts a ORS after printing. ORS stands for "output record separator" and defaults to the new line. So whenever you say print "hi" awk prints "hi" + new line.

This can be changed in two different ways: using an empty ORS or using printf.

Using an empty ORS

awk -v ORS= '1' <<< "hello
man"

This returns "helloman", all together.

The problem here is that not all awks accept setting an empty ORS, so you probably have to set another record separator.

awk -v ORS="-" '{print ...}' file

For example:

awk -v ORS="-" '1' <<< "hello
man"

Returns "hello-man-".

Using printf (preferable)

While print attaches ORS after the record, printf does not. Thus, printf "hello" just prints "hello", nothing else.

$ awk 'BEGIN{print "hello"; print "bye"}'
hello
bye
$ awk 'BEGIN{printf "hello"; printf "bye"}'
hellobye

Finally, note that in general this misses a final new line, so that the shell prompt will be in the same line as the last line of the output. To clean this, use END {print ""} so a new line will be printed after all the processing.

$ seq 5 | awk '{printf "%s", $0}'
12345$
#    ^ prompt here

$ seq 5 | awk '{printf "%s", $0} END {print ""}'
12345

You can now do this in most "modern" browsers!

Here is the original article I read (posted July 10, 2010): HTML5: Changing the browser-URL without refreshing page.

For a more in-depth look into pushState/replaceState/popstate (aka the HTML5 History API) see the MDN docs.

TL;DR, you can do this:

window.history.pushState("object or string", "Title", "/new-url");

See my answer to Modify the URL without reloading the page for a basic how-to.

The other answers show you how to make a list of data.frames when you already have a bunch of data.frames, e.g., d1, d2, .... Having sequentially named data frames is a problem, and putting them in a list is a good fix, but best practice is to avoid having a bunch of data.frames not in a list in the first place.

The other answers give plenty of detail of how to assign data frames to list elements, access them, etc. We'll cover that a little here too, but the Main Point is to say don't wait until you have a bunch of a data.frames to add them to a list. Start with the list.

The rest of the this answer will cover some common cases where you might be tempted to create sequential variables, and show you how to go straight to lists. If you're new to lists in R, you might want to also read What's the difference between [[ and [ in accessing elements of a list?.

Lists from the start

Don't ever create d1 d2 d3, ..., dn in the first place. Create a list d with n elements.

Reading multiple files into a list of data frames

This is done pretty easily when reading in files. Maybe you've got files data1.csv, data2.csv, ... in a directory. Your goal is a list of data.frames called mydata. The first thing you need is a vector with all the file names. You can construct this with paste (e.g., my_files = paste0("data", 1:5, ".csv")), but it's probably easier to use list.files to grab all the appropriate files: my_files <- list.files(pattern = "\\.csv$"). You can use regular expressions to match the files, read more about regular expressions in other questions if you need help there. This way you can grab all CSV files even if they don't follow a nice naming scheme. Or you can use a fancier regex pattern if you need to pick certain CSV files out from a bunch of them.

At this point, most R beginners will use a for loop, and there's nothing wrong with that, it works just fine.

my_data <- list()
for (i in seq_along(my_files)) {
    my_data[[i]] <- read.csv(file = my_files[i])
}

A more R-like way to do it is with lapply, which is a shortcut for the above

my_data <- lapply(my_files, read.csv)

Of course, substitute other data import function for read.csv as appropriate. readr::read_csv or data.table::fread will be faster, or you may also need a different function for a different file type.

Either way, it's handy to name the list elements to match the files

names(my_data) <- gsub("\\.csv$", "", my_files)
# or, if you prefer the consistent syntax of stringr
names(my_data) <- stringr::str_replace(my_files, pattern = ".csv", replacement = "")

Splitting a data frame into a list of data frames

This is super-easy, the base function split() does it for you. You can split by a column (or columns) of the data, or by anything else you want

mt_list = split(mtcars, f = mtcars$cyl)
# This gives a list of three data frames, one for each value of cyl

This is also a nice way to break a data frame into pieces for cross-validation. Maybe you want to split mtcars into training, test, and validation pieces.

groups = sample(c("train", "test", "validate"),
                size = nrow(mtcars), replace = TRUE)
mt_split = split(mtcars, f = groups)
# and mt_split has appropriate names already!

Simulating a list of data frames

Maybe you're simulating data, something like this:

my_sim_data = data.frame(x = rnorm(50), y = rnorm(50))

But who does only one simulation? You want to do this 100 times, 1000 times, more! But you don't want 10,000 data frames in your workspace. Use replicate and put them in a list:

sim_list = replicate(n = 10,
                     expr = {data.frame(x = rnorm(50), y = rnorm(50))},
                     simplify = F)

In this case especially, you should also consider whether you really need separate data frames, or would a single data frame with a "group" column work just as well? Using data.table or dplyr it's quite easy to do things "by group" to a data frame.

I didn't put my data in a list :( I will next time, but what can I do now?

If they're an odd assortment (which is unusual), you can simply assign them:

mylist <- list()
mylist[[1]] <- mtcars
mylist[[2]] <- data.frame(a = rnorm(50), b = runif(50))
...

If you have data frames named in a pattern, e.g., df1, df2, df3, and you want them in a list, you can get them if you can write a regular expression to match the names. Something like

df_list = mget(ls(pattern = "df[0-9]"))
# this would match any object with "df" followed by a digit in its name
# you can test what objects will be got by just running the
ls(pattern = "df[0-9]")
# part and adjusting the pattern until it gets the right objects.

Generally, mget is used to get multiple objects and return them in a named list. Its counterpart get is used to get a single object and return it (not in a list).

Combining a list of data frames into a single data frame

A common task is combining a list of data frames into one big data frame. If you want to stack them on top of each other, you would use rbind for a pair of them, but for a list of data frames here are three good choices:

# base option - slower but not extra dependencies
big_data = do.call(what = rbind, args = df_list)

# data table and dplyr have nice functions for this that
#  - are much faster
#  - add id columns to identify the source
#  - fill in missing values if some data frames have more columns than others
# see their help pages for details
big_data = data.table::rbindlist(df_list)
big_data = dplyr::bind_rows(df_list)

(Similarly using cbind or dplyr::bind_cols for columns.)

To merge (join) a list of data frames, you can see these answers. Often, the idea is to use Reduce with merge (or some other joining function) to get them together.

Why put the data in a list?

Put similar data in lists because you want to do similar things to each data frame, and functions like lapply, sapply do.call, the purrr package, and the old plyr l*ply functions make it easy to do that. Examples of people easily doing things with lists are all over SO.

Even if you use a lowly for loop, it's much easier to loop over the elements of a list than it is to construct variable names with paste and access the objects with get. Easier to debug, too.

Think of scalability. If you really only need three variables, it's fine to use d1, d2, d3. But then if it turns out you really need 6, that's a lot more typing. And next time, when you need 10 or 20, you find yourself copying and pasting lines of code, maybe using find/replace to change d14 to d15, and you're thinking this isn't how programming should be. If you use a list, the difference between 3 cases, 30 cases, and 300 cases is at most one line of code---no change at all if your number of cases is automatically detected by, e.g., how many .csv files are in your directory.

You can name the elements of a list, in case you want to use something other than numeric indices to access your data frames (and you can use both, this isn't an XOR choice).

Overall, using lists will lead you to write cleaner, easier-to-read code, which will result in fewer bugs and less confusion.

lista = list.sort(lista)

This should be

lista.sort()

The .sort() method is in-place, and returns None. If you want something not in-place, which returns a value, you could use

sorted_list = sorted(lista)

Aside #1: please don't call your lists list. That clobbers the builtin list type.

Aside #2: I'm not sure what this line is meant to do:

print str("value 1a")+str(" + ")+str("value 2")+str(" = ")+str("value 3a ")+str("value 4")+str("\n")

is it simply

print "value 1a + value 2 = value 3a value 4"

? In other words, I don't know why you're calling str on things which are already str.

Aside #3: sometimes you use print("something") (Python 3 syntax) and sometimes you use print "something" (Python 2). The latter would give you a SyntaxError in py3, so you must be running 2.*, in which case you probably don't want to get in the habit or you'll wind up printing tuples, with extra parentheses. I admit that it'll work well enough here, because if there's only one element in the parentheses it's not interpreted as a tuple, but it looks strange to the pythonic eye..

The exception TypeError: 'NoneType' object is not subscriptable happens because the value of lista is actually None. You can reproduce TypeError that you get in your code if you try this at the Python command line:

None[0]

The reason that lista gets set to None is because the return value of list.sort() is None... it does not return a sorted copy of the original list. Instead, as the documentation points out, the list gets sorted in-place instead of a copy being made (this is for efficiency reasons).

If you do not want to alter the original version you can use

other_list = sorted(lista)

You can use the WooCommerce Layered Nav widget, which allows you to use different sets of attributes as filters for products. Here's the "official" description:

Shows a custom attribute in a widget which lets you narrow down the list of products when viewing product categories.

If you look into plugins/woocommerce/widgets/widget-layered_nav.php, you can see the way it operates with the attributes in order to set filters. The URL then looks like this:

http://yoursite.com/shop/?filtering=1&filter_min-kvadratura=181&filter_max-kvadratura=108&filter_obem-ohlajdane=111

... and the digits are actually the id-s of the different attribute values, that you want to set.

It's not possible to save content to the website using only client-side scripting such as JavaScript and jQuery, but by submitting the data in an AJAX POST request you could perform the other half very easily on the server-side.

However, I would not recommend having raw content such as scripts so easily writeable to your hosting as this could easily be exploited. If you want to learn more about AJAX POST requests, you can read the jQuery API page:

http://api.jquery.com/jQuery.post/

And here are some things you ought to be aware of if you still want to save raw script files on your hosting. You have to be very careful with security if you are handling files like this!

I just spend THREE WHOLE DAYS fighting against this issue.

I was using my ORACLE connection in Windows 7, and no problem. Last week I Just get a new computer with Windows 8. Install XAMPP 1.8.2. Every app PHP/MySQL on this server works fine. The problem came when I try to connect my php apps to Oracle DB.

Call to undefined function oci_pconnect()

And when I start/stop Apache with changes, a strange "Warning" on "PHP Startup" that goes to LOG with "PHP Warning: PHP Startup: in Unknown on line 0"

I did everything (uncommented php_oci8.dll and php_oci8_11g.dll, copy oci.dll to /ext directory, near /Apache and NOTHING it works. Download every version of Instant Client and NOTHING.

God came into my help. When I download ORACLE Instant Client 32 bits, everything works fine. phpinfo() displays oci8 info, and my app works fine.

So, NEVER MIND THAT YOUR WINDOWS VERSION BE x64. The link are between XAMPP and ORACLE Instant Client.

You could actually use xlsread to accomplish this. After first placing your sample data above in a file 'input_file.csv', here is an example for how you can get the numeric values, text values, and the raw data in the file from the three outputs from xlsread:

>> [numData,textData,rawData] = xlsread('input_file.csv')

numData =     % An array of the numeric values from the file

   51.9358    4.1833
   51.9354    4.1841
   51.9352    4.1846
   51.9343    4.1864
   51.9343    4.1864
   51.9341    4.1869


textData =    % A cell array of strings for the text values from the file

    'ABC'
    'ABC'
    'ABC'
    'ABC'
    'ABC'
    'ABC'


rawData =     % All the data from the file (numeric and text) in a cell array

    'ABC'    [51.9358]    [4.1833]
    'ABC'    [51.9354]    [4.1841]
    'ABC'    [51.9352]    [4.1846]
    'ABC'    [51.9343]    [4.1864]
    'ABC'    [51.9343]    [4.1864]
    'ABC'    [51.9341]    [4.1869]

You can then perform whatever processing you need to on the numeric data, then resave a subset of the rows of data to a new file using xlswrite. Here's an example:

I had a simular issue and resolved it using android:adjustViewBounds="true" on the ImageView.

<ImageView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:adjustViewBounds="true"
    android:contentDescription="@string/banner_alt"
    android:src="@drawable/banner_portrait" />

Your example is perfect: the field is private and it has a getter. This is the normal way to access a field. If you need a direct access to an object field, use reflection. Using reflection to get a field's value is a hack and should be used in extreme cases such as using a library whose code you cannot change.

The script from Erwinus works great, but isn't very clearly coded. I took the liberty to clean it up and decipher what it was doing. I've made these changes:

• Meaningful variable names
• Use of prototype.
• require() uses an argument variable
• No alert() messages are returned by default
• Fixed some syntax errors and scope issues I was getting

Thanks again to Erwinus, the functionality itself is spot on.

What you can do is the following;

Add a file called ROOT.xml in <catalina_home>/conf/Catalina/localhost/

This ROOT.xml will override the default settings for the root context of the tomcat installation for that engine and host (Catalina and localhost).

Enter the following to the ROOT.xml file;

<Context 
  docBase="<yourApp>" 
  path="" 
  reloadable="true" 
/>

Here, <yourApp> is the name of, well, your app.. :)

And there you go, your application is now the default application and will show up on http://localhost:8080

However, there is one side effect; your application will be loaded twice. Once for localhost:8080 and once for localhost:8080/yourApp. To fix this you can put your application OUTSIDE <catalina_home>/webapps and use a relative or absolute path in the ROOT.xml's docBase tag. Something like this;

<Context 
  docBase="/opt/mywebapps/<yourApp>" 
  path="" 
  reloadable="true" 
/>

And then it should be all OK!

Here is the OOP way of adding a colorbar:

fig, ax = plt.subplots()
im = ax.scatter(x, y, c=c)
fig.colorbar(im, ax=ax)

I hade same problem then i fixed like this

change "text/javascript"

to

type="application/json"

Sliding the space bar only works if you gave more then one input language selected.

In that case the space bar will also indicate the selected language and show arrows to indicate Sliding will change selection.

This is easy fast and changes the dictionary at the same time.

First response seems the mist accurate.

The following complete example will read an existing server.xml file from the current directory, append a new Server and re-write the file to server.xml. It does not work without an existing .xml file, so you will need to modify the code to handle that case.

import java.util.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.dom.*;
import org.w3c.dom.*;
import javax.xml.parsers.*;

public class AddXmlNode {
    public static void main(String[] args) throws Exception {

        DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
        Document document = documentBuilder.parse("server.xml");
        Element root = document.getDocumentElement();

        Collection<Server> servers = new ArrayList<Server>();
        servers.add(new Server());

        for (Server server : servers) {
            // server elements
            Element newServer = document.createElement("server");

            Element name = document.createElement("name");
            name.appendChild(document.createTextNode(server.getName()));
            newServer.appendChild(name);

            Element port = document.createElement("port");
            port.appendChild(document.createTextNode(Integer.toString(server.getPort())));
            newServer.appendChild(port);

            root.appendChild(newServer);
        }

        DOMSource source = new DOMSource(document);

        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        StreamResult result = new StreamResult("server.xml");
        transformer.transform(source, result);
    }

    public static class Server {
        public String getName() { return "foo"; }
        public Integer getPort() { return 12345; }
    }
}

Example server.xml file:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Servers>
  <server>
    <name>something</name>
    <port>port</port>
  </server>
</Servers>

The main change to your code is not creating a new "root" element. The above example just uses the current root node from the existing server.xml and then just appends a new Server element and re-writes the file.

 public void removeDuplicates() {
    ArrayList<Object> al = new ArrayList<Object>();
    al.add("java");
    al.add('a');
    al.add('b');
    al.add('a');
    al.add("java");
    al.add(10.3);
    al.add('c');
    al.add(14);
    al.add("java");
    al.add(12);

    System.out.println("Before Remove Duplicate elements:" + al);
    for (int i = 0; i < al.size(); i++) {
        for (int j = i + 1; j < al.size(); j++) {
            if (al.get(i).equals(al.get(j))) {
                al.remove(j);
                j--;
            }
        }
    }
    System.out.println("After Removing duplicate elements:" + al);
}

Before Remove Duplicate elements:

[java, a, b, a, java, 10.3, c, 14, java, 12]

After Removing duplicate elements:

[java, a, b, 10.3, c, 14, 12]

You can write:

AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);

 // ...Irrelevant code for customizing the buttons and title

LayoutInflater inflater = this.getLayoutInflater(); 

View dialogView= inflater.inflate(R.layout.alert_label_editor, null);                    
dialogBuilder.setView(dialogView);

Button button = (Button)dialogView.findViewById(R.id.btnName);

   button.setOnClickListener(new View.OnClickListener() {
       @Override
       public void onClick(View view) {

         //Commond here......

       }
   });

EditText editText = (EditText)
dialogView.findViewById(R.id.label_field); 

editText.setText("test label"); 

dialogBuilder.create().show();

I had the same error. I created a directory under views direcotry named users and created an index.blade.php file in it. When calling this file you should write users.index to indicate your path. Or just create index.blade.php file under views. hope this will help someone who gets the same problem

Basic difference between add() and replace() can be described as:

• add() is used for simply adding a fragment to some root element.
• replace() behaves similarly but at first it removes previous fragments and then adds next fragment.

We can see the exact difference when we use addToBackStack() together with add() or replace().

When we press back button after in case of add()... onCreateView is never called, but in case of replace(), when we press back button ... oncreateView is called every time.

One should note that in the case of array indexing, array[~i] amounts to reversed_array[i]. It can be seen as indexing starting from the end of the array:

[0, 1, 2, 3, 4, 5, 6, 7, 8]
    ^                 ^
    i                ~i

What you want is the outer HTML, not the inner HTML :

$('<some element/>')[0].outerHTML;

Just a note for .Net Core: We can use the FileContentResult and set the contentType to application/octet-stream if we want to send the raw bytes. Example:

[HttpGet("{id}")]
public IActionResult GetDocumentBytes(int id)
{
    byte[] byteArray = GetDocumentByteArray(id);
    return new FileContentResult(byteArray, "application/octet-stream");
}

Pixels(px) – corresponds to actual pixels on the screen. This is used if you want to give in terms of absolute pixels for width or height.

Density-independent Pixels (dp or dip) – an abstract unit that is based on the physical density of the screen. These units are relative to a 160 dpi screen, so one dp is one pixel on a 160 dpi screen. The ratio of dp-to-pixel will change with the screen density, but not necessarily in direct proportion. Note: The compiler accepts both “dip” and “dp”, though “dp” is more consistent with “sp”.

Scale-independent Pixels(sp) – this is like the dp unit, but it is also scaled by the user’s font size preference. It is recommend you use this unit when specifying font sizes, so they will be adjusted for both the screen density and user’s preference.

Always use dp and sp only. sp for font sizes and dp for everything else. It will make UI compatible for Android devices with different densities. You can learn more about pixel and dp from https://www.google.com/design/spec/layout/units-measurements.html#units-measurements-density-independent-pixels-dp-

If only names of regular files immediately contained within a directory (assume it's ~/dirs) are needed, you can do

find ~/docs -type f -maxdepth 1 > filenames.txt

In case you have to replace multiple values and if you don't mind "refactoring" your variable with as.factor(as.character(...)) you could try the following:

replace.values <- function(search, replace, x){
  stopifnot(length(search) == length(replace))
  xnew <- replace[ match(x, search) ]
  takeOld <- is.na(xnew) & !is.na(x)
  xnew[takeOld] <- x[takeOld]
  return(xnew)
}

iris$Species <- as.factor(search=c("oldValue1","oldValue2"),
                          replace=c("newValue1","newValue2"),
                          x=as.character(iris$Species))

If you are you trying to attach a child view to the RelativeLayout? you can do by following

RelativeLayout item = (RelativeLayout)findViewById(R.id.item);
View child = getLayoutInflater().inflate(R.layout.child, item, true);

Google has just released a cross-platform open source tool for inspecting APKs (among many other binary Android formats):

ClassyShark is a standalone binary inspection tool for Android developers. It can reliably browse any Android executable and show important info such as class interfaces and members, dex counts and dependencies. ClassyShark supports multiple formats including libraries (.dex, .aar, .so), executables (.apk, .jar, .class) and all Android binary XMLs: AndroidManifest, resources, layouts etc.

1. Use the carousel's indicators to display thumbnails.
2. Position the thumbnails outside of the main carousel with CSS.
3. Set the maximum height of the indicators to not be larger than the thumbnails.
4. Whenever the carousel has slid, update the position of the indicators, positioning the active indicator in the middle of the indicators.

I'm using this on my site (for example here), but I'm using some extra stuff to do lazy loading, meaning extracting the code isn't as straightforward as I would like it to be for putting it in a fiddle.

Also, my templating engine is smarty, but I'm sure you get the idea.

The meat...

Updating the indicators:

<ol class="carousel-indicators">
    {assign var='walker' value=0}
    {foreach from=$item["imagearray"] key="key" item="value"}
        <li data-target="#myCarousel" data-slide-to="{$walker}"{if $walker == 0} class="active"{/if}>
            <img src='http://farm{$value["farm"]}.static.flickr.com/{$value["server"]}/{$value["id"]}_{$value["secret"]}_s.jpg'>
        </li>

        {assign var='walker' value=1 + $walker}
    {/foreach}
</ol>

Changing the CSS related to the indicators:

.carousel-indicators {
    bottom:-50px;
    height: 36px;
    overflow-x: hidden;
    white-space: nowrap;
}

.carousel-indicators li {
    text-indent: 0;
    width: 34px !important;
    height: 34px !important;
    border-radius: 0;
}

.carousel-indicators li img {
    width: 32px;
    height: 32px;
    opacity: 0.5;
}

.carousel-indicators li:hover img, .carousel-indicators li.active img {
    opacity: 1;
}

.carousel-indicators .active {
    border-color: #337ab7;
}

When the carousel has slid, update the list of thumbnails:

$('#myCarousel').on('slid.bs.carousel', function() {
    var widthEstimate = -1 * $(".carousel-indicators li:first").position().left + $(".carousel-indicators li:last").position().left + $(".carousel-indicators li:last").width(); 
    var newIndicatorPosition = $(".carousel-indicators li.active").position().left + $(".carousel-indicators li.active").width() / 2;
    var toScroll = newIndicatorPosition + indicatorPosition;
    var adjustedScroll = toScroll - ($(".carousel-indicators").width() / 2);
    if (adjustedScroll < 0)
        adjustedScroll = 0;

    if (adjustedScroll > widthEstimate - $(".carousel-indicators").width())
        adjustedScroll = widthEstimate - $(".carousel-indicators").width();

    $('.carousel-indicators').animate({ scrollLeft: adjustedScroll }, 800);

    indicatorPosition = adjustedScroll;
});

And, when your page loads, set the initial scroll position of the thumbnails:

var indicatorPosition = 0;

For ListView inside ScrollView use NestedScrollView it can handle this functionality very easily:

<android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <android.support.v7.widget.RecyclerView
                android:id="@+id/recycler_view"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:padding="5dip"/>

        </LinearLayout>
    </android.support.v4.widget.NestedScrollView>

If you wrap your form elements in a form tag with a name attribute you can easily get the value using document.formName.radioGroupName.value.

<form name="myForm">
    <input type="radio" id="genderm" name="gender" value="male" />
    <label for="genderm">Male</label>
    <input type="radio" id="genderf" name="gender" value="female" />
    <label for="genderf">Female</label>
</form>

<script>
    var selected = document.forms.myForm.gender.value;
</script>

I installed the Role plugin under Jenkins-3.5, but it does not show the "Manage Roles" option under "Manage Jenkins", and when one follows the security install page from the wiki, all users are locked out instantly. I had to manually shutdown Jenkins on the server, restore the correct configuration settings (/me is happy to do proper backups) and restart Jenkins.

I didn't have high hopes, as that plugin was last updated in 2011

You can also try this:

db.emails.find($and:[{sent_at:{$exists:true},'sent_at':null}]).count()

Pass your comma-separated string into this function and it will return an array, and if a comma-separated string is not found then it will return null.

function splitTheString(CommaSepStr) {
    var ResultArray = null;

    // Check if the string is null or so.
    if (CommaSepStr!= null) {

        var SplitChars = ',';

        // Check if the string has comma of not will go to else
        if (CommaSepStr.indexOf(SplitChars) >= 0) {
            ResultArray = CommaSepStr.split(SplitChars);

        }
        else {

            // The string has only one value, and we can also check
            // the length of the string or time and cross-check too.
            ResultArray = [CommaSepStr];
        }
    }
    return ResultArray;
}

we can access/pass arguments/variables from one class to another class using object reference.

#Class1
class Test:
    def __init__(self):
        self.a = 10
        self.b = 20
        self.add = 0

    def calc(self):
        self.add = self.a+self.b

#Class 2
class Test2:
    def display(self):
        print('adding of two numbers: ',self.add)
#creating object for Class1
obj = Test()
#invoking calc method()
obj.calc()
#passing class1 object to class2
Test2.display(obj)

This is probably the simplest way:

data$rownumber = 1:dim(data)[1]

It's probably worth noting that if you want to select a row by its row index, you can do this with simple bracket notation

data[3,]

vs.

data[data$rownumber==3,]

So I'm not really sure what this new column accomplishes.

private void Test_Click(object sender, System.EventArgs e){
   string path;
   path = System.IO.Path.GetDirectoryName( 
      System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase );
    Console.WriiteLine( path );  
}

Make sure you follow the language definition for JSON. In your second example, the section:

"labs":[{
    ""
}]

Is invalid since an object must be composed of zero or more key-value pairs "a" : "b", where "b" may be any valid value. Some parsers may automatically interpret { "" } to be { "" : null }, but this is not a clearly defined case.

Also, you are using a nested array of objects [{}] quite a bit. I would only do this if:

1. There is no good "identifier" string for each object in the array.
2. There is some clear reason for having an array over a key-value for that entry.

Or you can convert it into Char Array first by:

string Something = "1,5,12,34,";
char[] SomeGoodThing=Something.ToCharArray[];

Now you have each character indexed:

SomeGoodThing[0] -> '1'
SomeGoodThing[1] -> ','

Play around it

For a jQuery plugin try this

$.fn.removeClassLike = function(name) {
    return this.removeClass(function(index, css) {
        return (css.match(new RegExp('\\b(' + name + '\\S*)\\b', 'g')) || []).join(' ');
    });
};

or this

$.fn.removeClassLike = function(name) {
    var classes = this.attr('class');
    if (classes) {
        classes = classes.replace(new RegExp('\\b' + name + '\\S*\\s?', 'g'), '').trim();
        classes ? this.attr('class', classes) : this.removeAttr('class');
    }
    return this;
};

Edit: The second approach should be a bit faster because that runs just one regex replace on the whole class string. The first (shorter) uses jQuery's own removeClass method which iterates trough all the existing classnames and tests them for the given regex one by one, so under the hood it does more steps for the same job. However in real life usage the difference is negligible.

The accepted answer is correct as asked, below answers the opposite question of developing Android on VS Code.

Extensions

• Android : https://github.com/adelphes/android-dev-ext
• Emulator: https://github.com/DiemasMichiels/Emulator

Ultimately you can automate building and running your app on a device emulator by adding the function below to your $PATH and running runDebugApp <module> <start activity> from the integrated terminal:

# run android app
# usage runDebugApp [module] [fully qualified start activity com.package/com.package.MainActivity]
function runDebugApp(){
  ./gradlew -offline :"$1":installDebug && adb shell am start "$2" && adb logcat -d > logcat.log
}

Try to install your application by using yum command yum install application_name

Simply add $autoload['helper'] = array('url'); to autoload.php.

extern "C" doesn't really change the way that the compiler reads the code. If your code is in a .c file, it will be compiled as C, if it is in a .cpp file, it will be compiled as C++ (unless you do something strange to your configuration).

What extern "C" does is affect linkage. C++ functions, when compiled, have their names mangled -- this is what makes overloading possible. The function name gets modified based on the types and number of parameters, so that two functions with the same name will have different symbol names.

Code inside an extern "C" is still C++ code. There are limitations on what you can do in an extern "C" block, but they're all about linkage. You can't define any new symbols that can't be built with C linkage. That means no classes or templates, for example.

extern "C" blocks nest nicely. There's also extern "C++" if you find yourself hopelessly trapped inside of extern "C" regions, but it isn't such a good idea from a cleanliness perspective.

Now, specifically regarding your numbered questions:

Regarding #1: __cplusplus will stay defined inside of extern "C" blocks. This doesn't matter, though, since the blocks should nest neatly.

Regarding #2: __cplusplus will be defined for any compilation unit that is being run through the C++ compiler. Generally, that means .cpp files and any files being included by that .cpp file. The same .h (or .hh or .hpp or what-have-you) could be interpreted as C or C++ at different times, if different compilation units include them. If you want the prototypes in the .h file to refer to C symbol names, then they must have extern "C" when being interpreted as C++, and they should not have extern "C" when being interpreted as C -- hence the #ifdef __cplusplus checking.

To answer your question #3: functions without prototypes will have C++ linkage if they are in .cpp files and not inside of an extern "C" block. This is fine, though, because if it has no prototype, it can only be called by other functions in the same file, and then you don't generally care what the linkage looks like, because you aren't planning on having that function be called by anything outside the same compilation unit anyway.

For #4, you've got it exactly. If you are including a header for code that has C linkage (such as code that was compiled by a C compiler), then you must extern "C" the header -- that way you will be able to link with the library. (Otherwise, your linker would be looking for functions with names like _Z1hic when you were looking for void h(int, char)

5: This sort of mixing is a common reason to use extern "C", and I don't see anything wrong with doing it this way -- just make sure you understand what you are doing.

(ps: the answer given by Nick Craver is incorrect)

contentType specifies the format of data being sent to the server as part of request(it can be sent as part of response too, more on that later).

dataType specifies the expected format of data to be received by the client(browser).

Both are not interchangable.

• contentType is the header sent to the server, specifying the format of data(i.e the content of message body) being being to the server. This is used with POST and PUT requests. Usually when u send POST request, the message body comprises of passed in parameters like:

==============================

Sample request:

POST /search HTTP/1.1 
Content-Type: application/x-www-form-urlencoded 
<<other header>>

name=sam&age=35

==============================

The last line above "name=sam&age=35" is the message body and contentType specifies it as application/x-www-form-urlencoded since we are passing the form parameters in the message body. However we aren't limited to just sending the parameters, we can send json, xml,... like this(sending different types of data is especially useful with RESTful web services):

==============================

Sample request:

POST /orders HTTP/1.1
Content-Type: application/xml
<<other header>>

<order>
   <total>$199.02</total>
   <date>December 22, 2008 06:56</date>
...
</order>

==============================

So the ContentType this time is: application/xml, cause that's what we are sending. The above examples showed sample request, similarly the response send from the server can also have the Content-Type header specifying what the server is sending like this:

==============================

sample response:

HTTP/1.1 201 Created
Content-Type: application/xml
<<other headers>>

<order id="233">
   <link rel="self" href="http://example.com/orders/133"/>
   <total>$199.02</total>
   <date>December 22, 2008 06:56</date>
...
</order>

==============================

• dataType specifies the format of response to expect. Its related to Accept header. JQuery will try to infer it based on the Content-Type of the response.

==============================

Sample request:

GET /someFolder/index.html HTTP/1.1
Host: mysite.org
Accept: application/xml
<<other headers>>

==============================

Above request is expecting XML from the server.

Regarding your question,

contentType: "application/json; charset=utf-8",
dataType: "json",

Here you are sending json data using UTF8 character set, and you expect back json data from the server. As per the JQuery docs for dataType,

The json type parses the fetched data file as a JavaScript object and returns the constructed object as the result data.

So what you get in success handler is proper javascript object(JQuery converts the json object for you)

whereas

contentType: "application/json",
dataType: "text",

Here you are sending json data, since you haven't mentioned the encoding, as per the JQuery docs,

If no charset is specified, data will be transmitted to the server using the server's default charset; you must decode this appropriately on the server side.

and since dataType is specified as text, what you get in success handler is plain text, as per the docs for dataType,

The text and xml types return the data with no processing. The data is simply passed on to the success handler

Use the rand function:

http://www.cplusplus.com/reference/clibrary/cstdlib/rand/

Quote:

A typical way to generate pseudo-random numbers in a determined range using rand is to use the modulo of the returned value by the range span and add the initial value of the range:

( value % 100 ) is in the range 0 to 99
( value % 100 + 1 ) is in the range 1 to 100
( value % 30 + 1985 ) is in the range 1985 to 2014

goto doesn't do anything in Java.

Behold, for the simplest answer is mind blowing:

outerHTML is supported down to Internet Explorer 4 !

Here is to do it with javascript even without jQuery

element.outerHTML = element.innerHTML

with jQuery element = $('b')[0]; or without jQuery element = document.querySelector('b');

If you want it as a function:

function unwrap(selector) {
    var nodelist = document.querySelectorAll(selector);
    Array.prototype.forEach.call(nodelist, function(item,i){
        item.outerHTML = item.innerHTML; // or item.innerText if you want to remove all inner html tags 
    })
}

unwrap('b')

This should work in all major browser including old IE. in recent browser, we can even call forEach right on the nodelist.

function unwrap(selector) {
    document.querySelectorAll('b').forEach( (item,i) => {
        item.outerHTML = item.innerText;
    } )
}

1) Check if you are using OnItemClickListener or OnClickListener (which is not supported for ListView)
Documentation Android Developers ListView

2) Check if you added Listener to your ListView properly. It's hooked on ListView not on ListAdapter!

ListView.setOnItemClickListener(listener);

3) If you need to use OnClickListener, check if you do use DialogInterface.OnClickListener or View.OnClickListener (they can be easily exchanged if not validated or if using both of them)

I just read in the MySQL documentation that SHOW FULL PROCESSLIST by default only lists the threads from your current user connection.

Quote from the MySQL SHOW FULL PROCESSLIST documentation:

If you have the PROCESS privilege, you can see all threads.

So you can enable the Process_priv column in your mysql.user table. Remember to execute FLUSH PRIVILEGES afterwards :)

You can use recursion in lambdas and defaultdict, no need to define names:

a = defaultdict((lambda f: f(f))(lambda g: lambda:defaultdict(g(g))))

Here's an example:

>>> a['new jersey']['mercer county']['plumbers']=3
>>> a['new jersey']['middlesex county']['programmers']=81
>>> a['new jersey']['mercer county']['programmers']=81
>>> a['new jersey']['middlesex county']['salesmen']=62
>>> a
defaultdict(<function __main__.<lambda>>,
        {'new jersey': defaultdict(<function __main__.<lambda>>,
                     {'mercer county': defaultdict(<function __main__.<lambda>>,
                                  {'plumbers': 3, 'programmers': 81}),
                      'middlesex county': defaultdict(<function __main__.<lambda>>,
                                  {'programmers': 81, 'salesmen': 62})})})

The de-facto standard way to split up complex functions in C is per argument:

printf("name: %s\targs: %s\tvalue %d\tarraysize %d\n", 
       sp->name, 
       sp->args, 
       sp->value, 
       sp->arraysize);

Or if you will:

const char format_str[] = "name: %s\targs: %s\tvalue %d\tarraysize %d\n";
...
printf(format_str, 
       sp->name, 
       sp->args, 
       sp->value, 
       sp->arraysize);

You shouldn't split up the string, nor should you use \ to break a C line. Such code quickly turns completely unreadable/unmaintainable.

It is really very disappointing that you can't do it with styles (<item name="android:textAllCaps">true</item>) or on each XML layout file with the textAllCaps attribute, and the only way to do it is actually using theString.toUpperCase() on each of the strings when you do a textViewXXX.setText(theString).

In my case, I did not wanted to have theString.toUpperCase() everywhere in my code but to have a centralized place to do it because I had some Activities and lists items layouts with TextViews that where supposed to be capitalized all the time (a title) and other who did not... so... some people may think is an overkill, but I created my own CapitalizedTextView class extending android.widget.TextView and overrode the setText method capitalizing the text on the fly.

At least, if the design changes or I need to remove the capitalized text in future versions, I just need to change to normal TextView in the layout files.

Now, take in consideration that I did this because the App's Designer actually wanted this text (the titles) in CAPS all over the App no matter the original content capitalization, and also I had other normal TextViews where the capitalization came with the the actual content.

This is the class:

package com.realactionsoft.android.widget;

import android.content.Context; 
import android.util.AttributeSet; 
import android.view.ViewTreeObserver; 
import android.widget.TextView;


public class CapitalizedTextView extends TextView implements ViewTreeObserver.OnPreDrawListener {

    public CapitalizedTextView(Context context) {
        super(context);
    }

    public CapitalizedTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CapitalizedTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public void setText(CharSequence text, BufferType type) {
        super.setText(text.toString().toUpperCase(), type);
    }

}

And whenever you need to use it, just declare it with all the package in the XML layout:

<com.realactionsoft.android.widget.CapitalizedTextView 
        android:id="@+id/text_view_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

Some will argue that the correct way to style text on a TextView is to use a SpannableString, but I think that would be even a greater overkill, not to mention more resource-consuming because you'll be instantiating another class than TextView.

First check the $_GET['s'] is set or not. Change your conditions like this

<?php
if (isset($_GET['s']) && $_GET['s'] == 'jwshxnsyllabus')
echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/jwshxnporsyllabus.xml',         '../bibliographies/jwshxnbibliography_')\">";
elseif (isset($_GET['s']) && $_GET['s'] == 'aquinas')
echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/AquinasSyllabus.xml')\">"; 
elseif (isset($_GET['s']) && $_GET['s'] == 'POP2')
echo "<body onload=\"loadSyllabi('POP2')\">";
elseif (isset($_GET['s']) && $_GET['s'] == null)
echo "<body>"
?>

And also handle properly your ifelse conditions

You're trying to assign three separate string literals to a single string variable. A valid string variable would be 'John, Sarah, George'. If you want embedded single quotes between the double quotes, you have to escape them.

Also, your actual SELECT won't work, because SQL databases won't parse the string variable out into individual literal values. You need to use dynamic SQL instead, and then execute that dynamic SQL statement. (Search this site for dynamic SQL, with the database engine you're using as the topic (as in [sqlserver] dynamic SQL), and you should get several examples.)

<input type="text" formControlName="gsm" (input)="formatGsm($event.target.value)">

formatGsm(inputValue: String): String {
  const value = inputValue.replace(/[^0-9]/g, ''); // remove except digits
  let format = '(***) *** ** **'; // You can change format

  for (let i = 0; i < value.length; i++) {
    format = format.replace('*', value.charAt(i));
  }

  if (format.indexOf('*') >= 0) {
    format = format.substring(0, format.indexOf('*'));
  }

  return format.trim();
}

You can use code as below when

using Image as Loading

<asp:UpdateProgress id="updateProgress" runat="server">
    <ProgressTemplate>
        <div style="position: fixed; text-align: center; height: 100%; width: 100%; top: 0; right: 0; left: 0; z-index: 9999999; background-color: #000000; opacity: 0.7;">
            <asp:Image ID="imgUpdateProgress" runat="server" ImageUrl="~/images/ajax-loader.gif" AlternateText="Loading ..." ToolTip="Loading ..." style="padding: 10px;position:fixed;top:45%;left:50%;" />
        </div>
    </ProgressTemplate>
</asp:UpdateProgress>

using Text as Loading

<asp:UpdateProgress id="updateProgress" runat="server">
    <ProgressTemplate>
        <div style="position: fixed; text-align: center; height: 100%; width: 100%; top: 0; right: 0; left: 0; z-index: 9999999; background-color: #000000; opacity: 0.7;">
            <span style="border-width: 0px; position: fixed; padding: 50px; background-color: #FFFFFF; font-size: 36px; left: 40%; top: 40%;">Loading ...</span>
        </div>
    </ProgressTemplate>
</asp:UpdateProgress>

Wasn't sure if you meant which Oracle users can read\write with the directory or the correlation of the permissions between Oracle Directory Object and the underlying Operating System Directory.

As DCookie has covered the Oracle side of the fence, the following is taken from the Oracle documentation found here.

Privileges granted for the directory are created independently of the permissions defined for the operating system directory, and the two may or may not correspond exactly. For example, an error occurs if sample user hr is granted READ privilege on the directory object but the corresponding operating system directory does not have READ permission defined for Oracle Database processes.

What is missing in the question and all the answers is that you might need the passphrase to read public data from the PKCS#12 (.pfx) keystore. If you need a passphrase or not depends on how the PKCS#12 file was created. You can check the ASN1 structure of the file (by running it through a ASN1 parser, openssl or certutil can do this too), if the PKCS#7 data (e.g. OID prefix 1.2.840.113549.1.7) is listed as 'encrypted' or with a cipher-spec or if the location of the data in the asn1 tree is below an encrypted node, you won't be able to read it without knowledge of the passphrase. It means your 'openssl pkcs12' command will fail with errors (output depends on the version). For those wondering why you might be interested in the certificate of a PKCS#12 without knowledge of the passphrase. Imagine you have many keystores and many phassphrases and you are really bad at keeping them organized and you don't want to test all combinations, the certificate inside the file could help you find out which password it might be. Or you are developing software to migrate/renew a keystore and you need to decide in advance which procedure to initiate based on the contained certicate without user interaction. So the latter examples work without passphrase depending on the PKCS#12 structure.

Just wanted to add that, because I didn't find an answer myself and spend a lot of time to figure it out.

You need to make a class library and not a Console Application. The console application is translated into an .exe whereas the class library will then be compiled into a dll which you can reference in your windows project.

• Right click on your Console Application -> Properties -> Change the Output type to Class Library

You can do either of the following:

1. Use css attribute "line-height" and set it per table row (), this will also vertically center the content within

2. Set "display" css attribute to "block" and as the following:

td 
{
  display: block;
  overflow-y: hidden;
  max-height: 20px;
}

good luck!

It is very simple: Use the command:

docker-compose restart worker

You can set the time to wait for stop before killing the container (in seconds)

docker-compose restart -t 30 worker

Note that this will restart the container but without rebuilding it. If you want to apply your changes and then restart, take a look at the other answers.

It is an abbreviation for 'optional' , used for optional software in some distros.

you definitively want a List:

The List interface provides four methods for positional (indexed) access to list elements. Lists (like Java arrays) are zero based.

Also

Note that these operations may execute in time proportional to the index value for some implementations (the LinkedList class, for example). Thus, iterating over the elements in a > list is typically preferable to indexing through it if the caller does not know the implementation.

If you need the index in order to modify your collection you should note that List provides a special ListIterator that allow you to get the index:

List<String> names = Arrays.asList("Davide", "Francesco", "Angelocola");
ListIterator<String> i = names.listIterator();

while (i.hasNext()) {
    System.out.format("[%d] %s\n", i.nextIndex(), i.next());
}

I know I'm pretty late to the conversation, but I had this problem too. I think the issue was my company's firewall. My solution was to unplug from the network, connect to our open wireless and then force an update via Eclipse. This resolved everything.

use

require_once(__DIR__.'/_path/_of/_filename.php');

This will also help in importing files in from different folders. Try extends method to inherit the classes in that file and reuse the functions

How do Python's any and all functions work?

any and all take iterables and return True if any and all (respectively) of the elements are True.

>>> any([0, 0.0, False, (), '0']), all([1, 0.0001, True, (False,)])
(True, True)            #   ^^^-- truthy non-empty string
>>> any([0, 0.0, False, (), '']), all([1, 0.0001, True, (False,), {}])
(False, False)                                                #   ^^-- falsey

If the iterables are empty, any returns False, and all returns True.

>>> any([]), all([])
(False, True)

I was demonstrating all and any for students in class today. They were mostly confused about the return values for empty iterables. Explaining it this way caused a lot of lightbulbs to turn on.

Shortcutting behavior

They, any and all, both look for a condition that allows them to stop evaluating. The first examples I gave required them to evaluate the boolean for each element in the entire list.

(Note that list literal is not itself lazily evaluated - you could get that with an Iterator - but this is just for illustrative purposes.)

Here's a Python implementation of any and all:

def any(iterable):
    for i in iterable:
        if i:
            return True
    return False # for an empty iterable, any returns False!

def all(iterable):
    for i in iterable:
        if not i:
            return False
    return True  # for an empty iterable, all returns True!

Of course, the real implementations are written in C and are much more performant, but you could substitute the above and get the same results for the code in this (or any other) answer.

all

all checks for elements to be False (so it can return False), then it returns True if none of them were False.

>>> all([1, 2, 3, 4])                 # has to test to the end!
True
>>> all([0, 1, 2, 3, 4])              # 0 is False in a boolean context!
False  # ^--stops here!
>>> all([])
True   # gets to end, so True!

any

The way any works is that it checks for elements to be True (so it can return True), then it returnsFalseif none of them wereTrue`.

>>> any([0, 0.0, '', (), [], {}])     # has to test to the end!
False
>>> any([1, 0, 0.0, '', (), [], {}])  # 1 is True in a boolean context!
True   # ^--stops here!
>>> any([])
False   # gets to end, so False!

I think if you keep in mind the short-cutting behavior, you will intuitively understand how they work without having to reference a Truth Table.

Evidence of all and any shortcutting:

First, create a noisy_iterator:

def noisy_iterator(iterable):
    for i in iterable:
        print('yielding ' + repr(i))
        yield i

and now let's just iterate over the lists noisily, using our examples:

>>> all(noisy_iterator([1, 2, 3, 4]))
yielding 1
yielding 2
yielding 3
yielding 4
True
>>> all(noisy_iterator([0, 1, 2, 3, 4]))
yielding 0
False

We can see all stops on the first False boolean check.

And any stops on the first True boolean check:

>>> any(noisy_iterator([0, 0.0, '', (), [], {}]))
yielding 0
yielding 0.0
yielding ''
yielding ()
yielding []
yielding {}
False
>>> any(noisy_iterator([1, 0, 0.0, '', (), [], {}]))
yielding 1
True

The source

Let's look at the source to confirm the above.

Here's the source for any:

static PyObject *
builtin_any(PyObject *module, PyObject *iterable)
{
    PyObject *it, *item;
    PyObject *(*iternext)(PyObject *);
    int cmp;

    it = PyObject_GetIter(iterable);
    if (it == NULL)
        return NULL;
    iternext = *Py_TYPE(it)->tp_iternext;

    for (;;) {
        item = iternext(it);
        if (item == NULL)
            break;
        cmp = PyObject_IsTrue(item);
        Py_DECREF(item);
        if (cmp < 0) {
            Py_DECREF(it);
            return NULL;
        }
        if (cmp > 0) {
            Py_DECREF(it);
            Py_RETURN_TRUE;
        }
    }
    Py_DECREF(it);
    if (PyErr_Occurred()) {
        if (PyErr_ExceptionMatches(PyExc_StopIteration))
            PyErr_Clear();
        else
            return NULL;
    }
    Py_RETURN_FALSE;
}

And here's the source for all:

static PyObject *
builtin_all(PyObject *module, PyObject *iterable)
{
    PyObject *it, *item;
    PyObject *(*iternext)(PyObject *);
    int cmp;

    it = PyObject_GetIter(iterable);
    if (it == NULL)
        return NULL;
    iternext = *Py_TYPE(it)->tp_iternext;

    for (;;) {
        item = iternext(it);
        if (item == NULL)
            break;
        cmp = PyObject_IsTrue(item);
        Py_DECREF(item);
        if (cmp < 0) {
            Py_DECREF(it);
            return NULL;
        }
        if (cmp == 0) {
            Py_DECREF(it);
            Py_RETURN_FALSE;
        }
    }
    Py_DECREF(it);
    if (PyErr_Occurred()) {
        if (PyErr_ExceptionMatches(PyExc_StopIteration))
            PyErr_Clear();
        else
            return NULL;
    }
    Py_RETURN_TRUE;
}

HTML5 download attribute

Just to allow user to download the image or other file you may use the HTML5 download attribute.

Static file download

<a href="/images/image-name.jpg" download>
<!-- OR -->
<a href="/images/image-name.jpg" download="new-image-name.jpg"> 

Dynamic file download

In cases requesting image dynamically it is possible to emulate such download.

If your image is already loaded and you have the base64 source then:

function saveBase64AsFile(base64, fileName) {
    var link = document.createElement("a");

    document.body.appendChild(link); // for Firefox

    link.setAttribute("href", base64);
    link.setAttribute("download", fileName);
    link.click();
}

Otherwise if image file is downloaded as Blob you can use FileReader to convert it to Base64:

function saveBlobAsFile(blob, fileName) {
    var reader = new FileReader();

    reader.onloadend = function () {    
        var base64 = reader.result ;
        var link = document.createElement("a");

        document.body.appendChild(link); // for Firefox

        link.setAttribute("href", base64);
        link.setAttribute("download", fileName);
        link.click();
    };

    reader.readAsDataURL(blob);
}

Firefox

The anchor tag you are creating also needs to be added to the DOM in Firefox, in order to be recognized for click events (Link).

IE is not supported: Caniuse link

The double curly brackets are processed via Blade -- not just plain PHP. This syntax basically echos the calculated value.

{{ Request::segment(1) }} 

When you create table than you can give like follows.

CREATE TABLE categories(
cat_id int not null auto_increment primary key,
cat_name varchar(255) not null,
cat_description text
) ENGINE=InnoDB;


CREATE TABLE products(
   prd_id int not null auto_increment primary key,
   prd_name varchar(355) not null,
   prd_price decimal,
   cat_id int not null,
   FOREIGN KEY fk_cat(cat_id)
   REFERENCES categories(cat_id)
   ON UPDATE CASCADE
   ON DELETE RESTRICT
)ENGINE=InnoDB;

and when after the table create like this

   ALTER table_name
    ADD CONSTRAINT constraint_name
    FOREIGN KEY foreign_key_name(columns)
    REFERENCES parent_table(columns)
    ON DELETE action
    ON UPDATE action;

Following on example for it.

CREATE TABLE vendors(
    vdr_id int not null auto_increment primary key,
    vdr_name varchar(255)
)ENGINE=InnoDB;

ALTER TABLE products 
ADD COLUMN vdr_id int not null AFTER cat_id;

To add a foreign key to the products table, you use the following statement:

ALTER TABLE products
ADD FOREIGN KEY fk_vendor(vdr_id)
REFERENCES vendors(vdr_id)
ON DELETE NO ACTION
ON UPDATE CASCADE;

For drop the key

ALTER TABLE table_name 
DROP FOREIGN KEY constraint_name;

Hope this help to learn FOREIGN keys works

In my rails (rails 4.2) project, I use

Model.last(10) # get the last 10 record order by id

and it works.

localhost is a special hostname that almost always resolves to 127.0.0.1. If you ask someone else to connect to http://localhost they'll be connecting to their computer instead or yours.

To share your web server with someone else you'll need to find your IP address or your hostname and provide that to them instead. On windows you can find this with ipconfig /all on a command line.

You'll also need to make sure any firewalls you may have configured allow traffic on port 80 to connect to the WAMP server.

JDO is dead

JDO is not dead actually so please check your facts. JDO 2.2 was released in Oct 2008 JDO 2.3 is under development.

This is developed openly, under Apache. More releases than JPA has had, and its ORM specification is still in advance of even the JPA2 proposed features

Simple answer is here:

<div style="text-align: right;">
    anything:
    <select id="locality-dropdown" name="locality" class="cls" style="width: 200px; height: 28px; overflow:auto;">
    </select>
</div>

"Employed Russian" is among the best answer, and I think all other suggested answer may not work. The reason is simply because when an application is first created, all its the APIs it needs are resolved at compile time. Using "ldd" u can see all the statically linked dependencies:

ldd /usr/lib/firefox/firefox
    linux-vdso.so.1 =>  (0x00007ffd5c5f0000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f727e708000)
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f727e500000)
    libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f727e1f8000)
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f727def0000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f727db28000)
    /lib64/ld-linux-x86-64.so.2 (0x00007f727eb78000)
    libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f727d910000)

But at runtime, firefox will also load many other dynamic libraries, eg (for firefox) there are many "glib"-labelled libraries loaded (even though statically linked there are none):

 /usr/lib/x86_64-linux-gnu/libdbus-glib-1.so.2.2.2
 /lib/x86_64-linux-gnu/libglib-2.0.so.0.4002.0
 /usr/lib/x86_64-linux-gnu/libavahi-glib.so.1.0.2

Manytimes, you can see names of one version being soft-linked into another version. Eg:

lrwxrwxrwx 1 root root     23 Dec 21  2014 libdbus-glib-1.so.2 -> libdbus-glib-1.so.2.2.2
-rw-r--r-- 1 root root 160832 Mar  1  2013 libdbus-glib-1.so.2.2.2

This therefore means different version of "libraries" exists in one system - which is not a problem as it is the same file, and it will provide compatibilities when applications have multiple versions dependencies.

Therefore, at the system level, all the libraries are almost interdependent on one another, and just changing the libraries loading priority via manipulating LD_PRELOAD or LD_LIBRARY_PATH will not help - even it can load, runtime it may still crash.

Best alternative is chroot (mentioned by ER briefly): but for this you will need to recreate the entire environment in which is the original binary execute - usually starting from /lib, /usr/lib/, /usr/lib/x86 etc. You can either use "Buildroot", or YoctoProject, or just tar from an existing Distro environment. (like Fedora/Suse etc).

You need to do a while loop to get the result from the SQL query, like this:

require_once('db.php');  
$sql="SELECT * FROM  modul1open WHERE idM1O>=(SELECT FLOOR( MAX( idM1O ) * RAND( ) )    
FROM modul1open) ORDER BY idM1O LIMIT 1";

$result = mysql_query($sql);

while($row = mysql_fetch_array($result, MYSQL_ASSOC)) {

    // If you want to display all results from the query at once:
    print_r($row);

    // If you want to display the results one by one
    echo $row['column1'];
    echo $row['column2']; // etc..

}

Also I would strongly recommend not using mysql_* since it's deprecated. Instead use the mysqli or PDO extension. You can read more about that here.

This will happen if you are making selection in code as;

   mSpinner.setSelection(0);

Instead of above statement use

   mSpinner.setSelection(0,false);//just simply do not animate it.

Edit: This method doesn't work for Mi Android Version Mi UI.

In my case I wanted to compare values in cells of column E with Cells in Column G

Highlight the selection of cells to be checked in column E.

Select Conditional Format: Highlight cell rules Select one of the choices in my case it was greater than. In the left hand field of pop up use =indirect("g"&row()) where g was the row I was comparing against.

Now the row you are formatting will highlight based on if it is greater than the selection in row G

This works for every cell in Column E compared to cell in Column G of the selection you made for column E.

If G2 is greater than E2 it formats

G3 is greater than E3 it formats etc

To get the size of the directory hdfs dfs -du -s -h /$yourDirectoryName can be used. hdfs dfsadmin -report can be used to see a quick cluster level storage report.

It's probably worth noting that Powershell v3 and up, contains a cmdlet called Invoke-WebRequest that has some curl-ish capabilities. The New-WebServiceProxy and Invoke-RestMethod cmdlets are probably worth mentioning too.

I'm not sure they will fit your needs or not, but although I'm not a Windows guy, I have to say I find the object approach PS takes, a lot easier to work with than utilities such as curl, wget etc. They may be worth taking a look at

One more solution is

Rails.application.routes.routes

I don't know about best (simplest? fastest? most readable?), but one way would be:

dict(zip([1, 2, 3, 4], [a, b, c, d]))

Don't live fanatically with the conventions that SUN have med up, do whats feel right to you and your team.

For example this is how eclipse do it, breaking the convention. Try adding implements Serializable and eclipse will ask to generate this line for you.

Update: There were special cases that was excluded didn't know that. I however withholds to do what you and your team seems fit.

I hope what you are trying to achieve is like this. For this please use Box layout.

package com.kcing.kailas.sample.client;

import javax.swing.BoxLayout;
import javax.swing.JCheckBox;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;
import javax.swing.WindowConstants;

public class Testing extends JFrame {

    private JPanel jContentPane = null;

    public Testing() {
        super();
        initialize();
    }

    private void initialize() {
        this.setSize(300, 200);
        this.setContentPane(getJContentPane());
        this.setTitle("JFrame");
    }

    private JPanel getJContentPane() {
        if (jContentPane == null) {
            jContentPane = new JPanel();
            jContentPane.setLayout(null);

            JPanel panel = new JPanel();

            panel.setBounds(61, 11, 81, 140);
            panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
            jContentPane.add(panel);

            JCheckBox c1 = new JCheckBox("Check1");
            panel.add(c1);
            c1 = new JCheckBox("Check2");
            panel.add(c1);
            c1 = new JCheckBox("Check3");
            panel.add(c1);
            c1 = new JCheckBox("Check4");
            panel.add(c1);
        }
        return jContentPane;
    }

    public static void main(String[] args) throws Exception {

}

First you need to set the android:imeOptions attribute equal to actionDone for your target EditText as seen below. That will change your ‘RETURN’ button in your EditText’s soft keyboard to a ‘DONE’ button.

<EditText 
    android:id="@+id/edittext_done"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="Enter some text"
    android:imeOptions="actionDone"
    android:singleLine="true"
    />

You can declare trk by the following ways : - either

trk : [{
    lat : String,
    lng : String
     }]

or

trk : { type : Array , "default" : [] }

In the second case during insertion make the object and push it into the array like

db.update({'Searching criteria goes here'},
{
 $push : {
    trk :  {
             "lat": 50.3293714,
             "lng": 6.9389939
           } //inserted data is the object to be inserted 
  }
});

or you can set the Array of object by

db.update ({'seraching criteria goes here ' },
{
 $set : {
          trk : [ {
                     "lat": 50.3293714,
                     "lng": 6.9389939
                  },
                  {
                     "lat": 50.3293284,
                     "lng": 6.9389634
                  }
               ]//'inserted Array containing the list of object'
      }
});

There could be many reason why document.getElementById doesn't work

• You have an invalid ID

  ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods ("."). (resource: What are valid values for the id attribute in HTML?)

• you used some id that you already used as <meta> name in your header (e.g. copyright, author... ) it looks weird but happened to me: if your 're using IE take a look at (resource: http://www.phpied.com/getelementbyid-description-in-ie/)

• you're targeting an element inside a frame or iframe. In this case if the iframe loads a page within the same domain of the parent you should target the contentdocument before looking for the element (resource: Calling a specific id inside a frame)

• you're simply looking to an element when the node is not effectively loaded in the DOM, or maybe it's a simple misspelling

I doubt you used same ID twice or more: in that case document.getElementById should return at least the first element

I'm not sure I understand your intent perfectly, but perhaps the following would be close to what you want:

select n1.name, n1.author_id, count_1, total_count
  from (select id, name, author_id, count(1) as count_1
          from names
          group by id, name, author_id) n1
inner join (select id, author_id, count(1) as total_count
              from names
              group by id, author_id) n2
  on (n2.id = n1.id and n2.author_id = n1.author_id)

Unfortunately this adds the requirement of grouping the first subquery by id as well as name and author_id, which I don't think was wanted. I'm not sure how to work around that, though, as you need to have id available to join in the second subquery. Perhaps someone else will come up with a better solution.

Share and enjoy.

For IE8 or console support limited to console.log (no debug, trace, ...) you can do the following:

• If console OR console.log undefined: Create dummy functions for console functions (trace, debug, log, ...)

  window.console = { debug : function() {}, ...};

• Else if console.log is defined (IE8) AND console.debug (any other) is not defined: redirect all logging functions to console.log, this allows to keep those logs !

  window.console = { debug : window.console.log, ...};

Not sure about the assert support in various IE versions, but any suggestions are welcome.

Just in case this helps anyone else:

If you're going to be adding the TimeOut directive, and your website uses multiple vhosts (eg. one for port 80, one for port 443), then don't forget to add the directive to all of them!

That’s right, Executors.newCachedThreadPool() isn't a great choice for server code that's servicing multiple clients and concurrent requests.

Why? There are basically two (related) problems with it:

1. It's unbounded, which means that you're opening the door for anyone to cripple your JVM by simply injecting more work into the service (DoS attack). Threads consume a non-negligible amount of memory and also increase memory consumption based on their work-in-progress, so it's quite easy to topple a server this way (unless you have other circuit-breakers in place).

2. The unbounded problem is exacerbated by the fact that the Executor is fronted by a SynchronousQueue which means there's a direct handoff between the task-giver and the thread pool. Each new task will create a new thread if all existing threads are busy. This is generally a bad strategy for server code. When the CPU gets saturated, existing tasks take longer to finish. Yet more tasks are being submitted and more threads created, so tasks take longer and longer to complete. When the CPU is saturated, more threads is definitely not what the server needs.

Here are my recommendations:

Use a fixed-size thread pool Executors.newFixedThreadPool or a ThreadPoolExecutor. with a set maximum number of threads;

To replace a path within files (avoiding escape characters) you may use the following command:

sed -i 's@old_path@new_path@g'

The @ sign means that all of the special characters should be ignored in a following string.

>>> s = 'sdsd'
>>> s.upper()
'SDSD'

See String Methods.

For a period I had to extract the Media ID myself quite frequently, so I wrote my own script (very likely it's based on some of the examples here). Together with other small scripts I used frequently, I started to upload them on www.findinstaid.com for my own quick access.

I added the option to enter a username to get the media ID of the 12 most recent posts, or to enter a URL to get the media ID of a specific post.

If it's convenient, everyone can use the link (I don't have any adds or any other monetary interests in the website - I only have a referral link on the 'Audit' tab to www.auditninja.io which I do also own, but also on this site, there are no adds or monetary interests - just hobby projects).

The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.

If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.

Start simple

Conceptually, the simplest regular expressions are literal characters. The pattern N matches the character 'N'.

Regular expressions next to each other match sequences. For example, the pattern Nick matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.

If you've ever used grep on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re in grep refers to regular expressions.)

Order from the menu

Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c] matches either 'a' or 'b' or 'c'.

The pattern . is special: rather than matching a literal dot only, it matches any character^†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...].

Think of character classes as menus: pick just one.

Helpful shortcuts

Using . can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]. Digits are a frequent match target, so you could instead use the shortcut \d. Others are \s (whitespace) and \w (word characters: alphanumerics or underscore).

The uppercased variants are their complements, so \S matches any non-whitespace character, for example.

Once is not enough

From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c matches 'abc' or 'ac' because the ? quantifier makes the subpattern it modifies optional. Other quantifiers are

• * (zero or more times)
• + (one or more times)
• {n} (exactly n times)
• {n,} (at least n times)
• {n,m} (at least n times but no more than m times)

Putting some of these blocks together, the pattern [Nn]*ick matches all of

• ick
• Nick
• nick
• Nnick
• nNick
• nnick
• (and so on)

The first match demonstrates an important lesson: * always succeeds! Any pattern can match zero times.

A few other useful examples:

• [0-9]+ (and its equivalent \d+) matches any non-negative integer
• \d{4}-\d{2}-\d{2} matches dates formatted like 2019-01-01

Grouping

A quantifier modifies the pattern to its immediate left. You might expect 0abc+0 to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c. This means 0abc+0 matches '0abc0', '0abcc0', '0abccc0', and so on.

To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr.

Alternation

Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |, e.g., (Nick|nick).

For another example, you could equivalently write [a-c] as a|b|c, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.

Escaping

Although some characters match themselves, others have special meanings. The pattern \d+ doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+. A backslash removes the special meaning from the following character.

Greediness

Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.

For example, say the input is

"Hello," she said, "How are you?"

You might expect ".+" to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.

To switch from greedy to what you might think of as cautious, add an extra ? to the quantifier. Now you understand how \((.+?)\), the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.

If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.

(As to your confusion, I don't know of any regular-expression dialect where ((.+?)) would do the same thing. I suspect something got lost in transmission somewhere along the way.)

Anchors

Use the special pattern ^ to match only at the beginning of your input and $ to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.

Say you want to match comments of the form

-- This is a comment --

you'd write ^--\s+(.+)\s+--$.

Build your own

Regular expressions are recursive, so now that you understand these basic rules, you can combine them however you like.

Footnote

†: The statement above that . matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n", but in practice you rarely expect a pattern such as .+ to cross a newline boundary. Perl regexes have a /s switch and Java Pattern.DOTALL, for example, to make . match any character at all. For languages that don't have such a feature, you can use something like [\s\S] to match "any whitespace or any non-whitespace", in other words anything.

There is an option to in SSIS to save passwords(to access DB or anyother stuff), the default setting is "EncryptSensitiveWithUserKey"... You need to change this.

The connect router has now been removed (https://github.com/senchalabs/connect/issues/262), the author stating that you should use a framework on top of connect (like Express) for routing.

Express currently treats app.get("/foo*") as app.get(/\/foo(.*)/), removing the need for two separate routes. This is in contrast to the previous answer (referring to the now removed connect router) which stated that "* in a path is replaced with .+".

Update: Express now uses the "path-to-regexp" module (since Express 4.0.0) which maintains the same behavior in the version currently referenced. It's unclear to me whether the latest version of that module keeps the behavior, but for now this answer stands.

Edit /etc/conf.apf. Set DEVEL_MODE="0". DEVEL_MODE set to 1 will add a cron job to stop apf after 5 minutes.

More compact way to get the difference between two datetime objects and then convert the difference into seconds is shown below (Python 3x):

from datetime import datetime
        
time1 = datetime.strftime('18 01 2021', '%d %m %Y')
    
time2 = datetime.strftime('19 01 2021', '%d %m %Y')

difference = time2 - time1

difference_in_seconds = difference.total_seconds()

Implementations

Although the reference implementation of reStructuredText is written in Python, there are reStructuredText parsers in other languages too.

Python - Docutils

The main distribution of reStructuredText is the Python Docutils package. It contains several conversion tools:

• rst2html - from reStructuredText to HTML
• rst2xml - from reStructuredText to XML
• rst2latex - from reStructuredText to LaTeX
• rst2odt - from reStructuredText to ODF Text (word processor) document.
• rst2s5 - from reStructuredText to S5, a Simple Standards-based Slide Show System
• rst2man - from reStructuredText to Man page

Haskell - Pandoc

Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read Markdown and (subsets of) reStructuredText, HTML, and LaTeX, and it can write Markdown, reStructuredText, HTML, LaTeX, ConTeXt, PDF, RTF, DocBook XML, OpenDocument XML, ODT, GNU Texinfo, MediaWiki markup, groff man pages, and S5 HTML slide shows.

There is an Pandoc online tool (POT) to try this library. Unfortunately, compared to the reStructuredText online renderer (ROR),

• POT truncates input rather more shortly. The POT user must render input in chunks that could be rendered whole by the ROR.
• POT output lacks the helpful error messages displayed by the ROR (and generated by docutils)

Java - JRst

JRst is a Java reStructuredText parser. It can currently output HTML, XHTML, DocBook xdoc and PDF, BUT seems to have serious problems: neither PDF or (X)HTML generation works using the current full download, result pages in (X)HTML are empty and PDF generation fails on IO problems with XSL files (not bundled??). Note that the original JRst has been removed from the website; a fork is found on GitHub.

Scala - Laika

Laika is a new library for transforming markup languages to other output formats. Currently it supports input from Markdown and reStructuredText and produce HTML output. The library is written in Scala but should be also usable from Java.

Perl

• Text::Restructured - Perl implementation of reStructuredText parser
• Dotiac::DTL::Addon::markup - Filters to work with common markup languages - support reStructuredText
• Pod::POM::View::Restructured - View for Pod::POM that outputs reStructuredText

PHP

• Gregwar/RST - A mature PHP5.3 parser with tests
• php-restructuredtext - A simple, incomplete (but functional) implementation

C#/.NET

• reStructuredText for ANTLR - A C# based parser with tests (in progress). It also provides the language server behind reStructuredText extension for Visual Studio Code.

Nim/C

The Nim compiler features the commands rst2htmland rst2tex which transform reStructuredText files to HTML and TeX files. The standard library provides the following modules (used by the compiler) to handle reStructuredText files programmatically:

• rst - implements a reStructuredText parser
• rstast - implements an AST for the reStructuredText parser
• rstgen - implements a generator of HTML/Latex from reStructuredText

Other 3rd party converters

Most (but not all) of these tools are based on Docutils (see above) and provide conversion to or from formats that might not be supported by the main distribution.

From reStructuredText

• restview - This pip-installable python package requires docutils, which does the actual rendering. restview's major ease-of-use feature is that, when you save changes to your document(s), it automagically re-renders and re-displays them. restview
  1. starts a small web server
  2. calls docutils to render your document(s) to HTML
  3. calls your device's browser to display the output HTML.
• rst2pdf - from reStructuredText to PDF
• rst2odp - from reStructuredText to ODF Presentation
• rst2beamer - from reStructuredText to LaTeX beamer Presentation class
• Wikir - from reStructuredText to a Google (and possibly other) Wiki formats
• rst2qhc - Convert a collection of reStructuredText files into a Qt (toolkit) Help file and (optional) a Qt Help Project file

To reStructuredText

• xml2rst is an XSLT script to convert Docutils internal XML representation (back) to reStructuredText
• Pandoc (see above) can also convert from Markdown, HTML and LaTeX to reStructuredText
• db2rst is a simple and limited DocBook to reStructuredText translator
• pod2rst - convert .pod files to reStructuredText files

Extensions

Some projects use reStructuredText as a baseline to build on, or provide extra functionality extending the utility of the reStructuredText tools.

Sphinx

The Sphinx documentation generator translates a set of reStructuredText source files into various output formats, automatically producing cross-references, indices etc.

rest2web

rest2web is a simple tool that lets you build your website from a single template (or as many as you want), and keep the contents in reStructuredText.

Pygments

Pygments is a generic syntax highlighter for general use in all kinds of software such as forum systems, Wikis or other applications that need to prettify source code. See Using Pygments in reStructuredText documents.

Free Editors

While any plain text editor is suitable to write reStructuredText documents, some editors have better support than others.

Emacs

The Emacs support via rst-mode comes as part of the Docutils package under /docutils/tools/editors/emacs/rst.el

Vim

The vim-common package for that comes with most GNU/Linux distributions has reStructuredText syntax highlight and indentation support of reStructuredText out of the box:

• reStructuredText syntax highlighting mode for vim
• VST (Vim reStructured Text) is a plugin for Vim7 with folding for reStructuredText
• Riv.vim - fresh vim plugin for authoring rst and Sphinx doc
• Previm: Vim plugin for live previewing of reStructuredText and other mark up documents

Geany

Geany, a small and lightweight Integrated Development Environment include support for reStructuredText from version 0.12 (October 10, 2007).

Leo

Leo, an outlining editor for programmers, supports reStructuredText via rst-plugin or via "@auto-rst" nodes (it's not well-documented, but @auto-rst nodes allow editing rst files directly, parsing the structure into the Leo outline).

It also provides a way to preview the resulting HTML, in a "viewrendered" pane.

FTE

The FTE Folding Text Editor - a free (licensed under the GNU GPL) text editor for developers. FTE has a mode for reStructuredText support. It provides color highlighting of basic RSTX elements and special menu that provide easy way to insert most popular RSTX elements to a document.

PyK

PyK is a successor of PyEdit and reStInPeace, written in Python with the help of the Qt4 toolkit.

Eclipse

The Eclipse IDE with the ReST Editor plug-in provides support for editing reStructuredText files.

NoTex

NoTex is a browser based (general purpose) text editor, with integrated project management and syntax highlighting. Plus it enables to write books, reports, articles etc. using rST and convert them to LaTex, PDF or HTML. The PDF files are of high publication quality and are produced via Sphinx with the Texlive LaTex suite.

Notepad++

Notepad++ is a general purpose text editor for Windows. It has syntax highlighting for many languages built-in and support for reStructuredText via a user defined language for reStructuredText.

Visual Studio Code

Visual Studio Code is a general purpose text editor for Windows/macOS/Linux. It has syntax highlighting for many languages built-in and supports reStructuredText via an extension from LeXtudio.

Dedicated reStructuredText Editors

• ReSTedit by Dinu Gherman and Bill Bumgarner
• Rest in Peace
• Enthought Tool Suite editor

Proprietary editors

Sublime Text

Sublime Text is a completely customizable and extensible source code editor available for Windows, OS X, and Linux. Registration is required for long-term use, but all functions are available in the unregistered version, with occasional reminders to purchase a license. Versions 2 and 3 (currently in beta) support reStructuredText syntax highlighting by default, and several plugins are available through the package manager Package Control to provide snippets and code completion, additional syntax highlighting, conversion to/from RST and other formats, and HTML preview in the browser.

BBEdit / TextWrangler

BBEdit (and its free variant TextWrangler) for Mac can syntax-highlight reStructuredText using this codeless language module.

Intype

Intype is a proprietary text editor for Windows, that support reStructuredText out of the box.

E Text Editor

E is a proprietary Text Editor licensed under the "Open Company License". It supports TextMate's bundles, so it should support reStructuredText the same way TextMate does.

PyCharm

PyCharm (and other IntelliJ platform IDEs?) has ReST/Sphinx support (syntax highlighting, autocomplete and preview).)

Wiki

here are some Wiki programs that support the reStructuredText markup as the native markup syntax, or as an add-on:

MediaWiki

MediaWiki reStructuredText extension allows for reStructuredText markup in MediaWiki surrounded by <rst> and </rst>.

This Wiki

This Wiki is a Webware for Python Wiki written by Ian Bicking. This wiki uses ReStructuredText for its markup.

rstiki

rstiki is a minimalist single-file personal wiki using reStructuredText syntax (via docutils) inspired by pwyky. It does not support authorship indication, versioning, hierarchy, chrome/framing/templating or styling. It leverages docutils/reStructuredText as the wiki syntax. As such, it's under 200 lines of code, and in a single file. You put it in a directory and it runs.

ikiwiki

Ikiwiki is a wiki compiler. It converts wiki pages into HTML pages suitable for publishing on a website. Ikiwiki stores pages and history in a revision control system such as Subversion or Git. There are many other features, including support for blogging, as well as a large array of plugins. It's reStructuredText plugin, however is somewhat limited and is not recommended as its' main markup language at this time.

Thank you guys for the help,

When I asked at first I didn't think it's even possible, but after your answers I googled and found this amazing tutorial:

http://blog.thomaslebrun.net/2011/11/html-5-how-to-customize-the-error-message-for-a-required-field/#.UsNN1BYrh2M

You should try to check the log generated by npm install.

I have faced the same issues, and I found the error that python2 is not found in the path (environment variable).

After installing Python, everything worked fine.

Pass a duration to show() and hide():

When a duration is provided, .show() becomes an animation method.

E.g. element.delay(1000).show(0)

DEMO

Swift 4

    private func createButton {
        let sayButtonT = UIButton(type: .custom)
        sayButtonT.addTarget(self, action: #selector(sayAction(_:)), for: .touchUpInside)
    }

    @objc private func sayAction(_ sender: UIButton?) {

    }

The answers are great. If you want to give a chance to another clustering method you can use hierarchical clustering and see how data is splitting.

> set.seed(2)
> x=matrix(rnorm(50*2), ncol=2)
> hc.complete = hclust(dist(x), method="complete")
> plot(hc.complete)

Depending on how many classes you need you can cut your dendrogram as;

> cutree(hc.complete,k = 2)
 [1] 1 1 1 2 1 1 1 1 1 1 1 1 1 2 1 2 1 1 1 1 1 2 1 1 1
[26] 2 1 1 1 1 1 1 1 1 1 1 2 2 1 1 1 2 1 1 1 1 1 1 1 2

If you type ?cutree you will see the definitions. If your data set has three classes it will be simply cutree(hc.complete, k = 3). The equivalent for cutree(hc.complete,k = 2) is cutree(hc.complete,h = 4.9).

In Workbench 6.3 go to Server menu and then Choose Data Export. The dialog that comes up allows you to do all three things you want.

Just be careful of Bitmap type from java platform call like from comm1x's and Gnzlt's answers, because it might return null. I think it is also more flexible if the parameter can be any Number and use infix for readability, depends on your coding style.

infix fun Bitmap.rotate(degrees: Number): Bitmap? {
    return Bitmap.createBitmap(
        this,
        0,
        0,
        width,
        height,
        Matrix().apply { postRotate(degrees.toFloat()) },
        true
    )
}

How to use?

bitmap rotate 90
// or
bitmap.rotate(90)

getElementById("id").removeAttribute("style");

if you are using jQuery then

$("#id").removeClass("classname");

As of Jan 2018 the latest URL is:

https://google.com/maps/search/your search string (address, landmark, city, etc. Spaces are ok)

Examples:

https://google.com/maps/search/empire state building

https://google.com/maps/search/1600 Pennsylvania Ave NW, Washington, DC 20500

The official MS line is "because it's not a functional operation" (ie it's a stateful operation).

Couldn't you do something like:

list.Select( x => x+1 )

or if you really need it in a List:

var someValues = new List<int>( list.Select( x => x+1 ) );

How about:

df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x

To do all these operations in one-liner:

setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))

#[1] name   age    gender
#<0 rows> (or 0-length row.names)

Or

data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))

<?php

  class Test {
     function MethodA(){
         echo __FUNCTION__ ;
     }
 }
 $test = new Test;
 echo $test->MethodA();
?>

Result: "MethodA";

Versioning of assemblies in .NET can be a confusing prospect given that there are currently at least three ways to specify a version for your assembly.

Here are the three main version-related assembly attributes:

// Assembly mscorlib, Version 2.0.0.0
[assembly: AssemblyFileVersion("2.0.50727.3521")]
[assembly: AssemblyInformationalVersion("2.0.50727.3521")]
[assembly: AssemblyVersion("2.0.0.0")]

By convention, the four parts of the version are referred to as the Major Version, Minor Version, Build, and Revision.

The AssemblyFileVersion is intended to uniquely identify a build of the individual assembly

Typically you’ll manually set the Major and Minor AssemblyFileVersion to reflect the version of the assembly, then increment the Build and/or Revision every time your build system compiles the assembly. The AssemblyFileVersion should allow you to uniquely identify a build of the assembly, so that you can use it as a starting point for debugging any problems.

On my current project we have the build server encode the changelist number from our source control repository into the Build and Revision parts of the AssemblyFileVersion. This allows us to map directly from an assembly to its source code, for any assembly generated by the build server (without having to use labels or branches in source control, or manually keeping any records of released versions).

This version number is stored in the Win32 version resource and can be seen when viewing the Windows Explorer property pages for the assembly.

The CLR does not care about nor examine the AssemblyFileVersion.

The AssemblyInformationalVersion is intended to represent the version of your entire product

The AssemblyInformationalVersion is intended to allow coherent versioning of the entire product, which may consist of many assemblies that are independently versioned, perhaps with differing versioning policies, and potentially developed by disparate teams.

“For example, version 2.0 of a product might contain several assemblies; one of these assemblies is marked as version 1.0 since it’s a new assembly that didn’t ship in version 1.0 of the same product. Typically, you set the major and minor parts of this version number to represent the public version of your product. Then you increment the build and revision parts each time you package a complete product with all its assemblies.” — Jeffrey Richter, [CLR via C# (Second Edition)] p. 57

The CLR does not care about nor examine the AssemblyInformationalVersion.

The AssemblyVersion is the only version the CLR cares about (but it cares about the entire AssemblyVersion)

The AssemblyVersion is used by the CLR to bind to strongly named assemblies. It is stored in the AssemblyDef manifest metadata table of the built assembly, and in the AssemblyRef table of any assembly that references it.

This is very important, because it means that when you reference a strongly named assembly, you are tightly bound to a specific AssemblyVersion of that assembly. The entire AssemblyVersion must be an exact match for the binding to succeed. For example, if you reference version 1.0.0.0 of a strongly named assembly at build-time, but only version 1.0.0.1 of that assembly is available at runtime, binding will fail! (You will then have to work around this using Assembly Binding Redirection.)

Confusion over whether the entire AssemblyVersion has to match. (Yes, it does.)

There is a little confusion around whether the entire AssemblyVersion has to be an exact match in order for an assembly to be loaded. Some people are under the false belief that only the Major and Minor parts of the AssemblyVersion have to match in order for binding to succeed. This is a sensible assumption, however it is ultimately incorrect (as of .NET 3.5), and it’s trivial to verify this for your version of the CLR. Just execute this sample code.

On my machine the second assembly load fails, and the last two lines of the fusion log make it perfectly clear why:

.NET Framework Version: 2.0.50727.3521

I think the source of this confusion is probably because Microsoft originally intended to be a little more lenient on this strict matching of the full AssemblyVersion, by matching only on the Major and Minor version parts:

“When loading an assembly, the CLR will automatically find the latest installed servicing version that matches the major/minor version of the assembly being requested.” — Jeffrey Richter, [CLR via C# (Second Edition)] p. 56

This was the behaviour in Beta 1 of the 1.0 CLR, however this feature was removed before the 1.0 release, and hasn’t managed to re-surface in .NET 2.0:

“Note: I have just described how you should think of version numbers. Unfortunately, the CLR doesn’t treat version numbers this way. [In .NET 2.0], the CLR treats a version number as an opaque value, and if an assembly depends on version 1.2.3.4 of another assembly, the CLR tries to load version 1.2.3.4 only (unless a binding redirection is in place). However, Microsoft has plans to change the CLR’s loader in a future version so that it loads the latest build/revision for a given major/minor version of an assembly. For example, on a future version of the CLR, if the loader is trying to find version 1.2.3.4 of an assembly and version 1.2.5.0 exists, the loader with automatically pick up the latest servicing version. This will be a very welcome change to the CLR’s loader — I for one can’t wait.” — Jeffrey Richter, [CLR via C# (Second Edition)] p. 164 (Emphasis mine)

As this change still hasn’t been implemented, I think it’s safe to assume that Microsoft had back-tracked on this intent, and it is perhaps too late to change this now. I tried to search around the web to find out what happened with these plans, but I couldn’t find any answers. I still wanted to get to the bottom of it.

So I emailed Jeff Richter and asked him directly — I figured if anyone knew what happened, it would be him.

He replied within 12 hours, on a Saturday morning no less, and clarified that the .NET 1.0 Beta 1 loader did implement this ‘automatic roll-forward’ mechanism of picking up the latest available Build and Revision of an assembly, but this behaviour was reverted before .NET 1.0 shipped. It was later intended to revive this but it didn’t make it in before the CLR 2.0 shipped. Then came Silverlight, which took priority for the CLR team, so this functionality got delayed further. In the meantime, most of the people who were around in the days of CLR 1.0 Beta 1 have since moved on, so it’s unlikely that this will see the light of day, despite all the hard work that had already been put into it.

The current behaviour, it seems, is here to stay.

It is also worth noting from my discussion with Jeff that AssemblyFileVersion was only added after the removal of the ‘automatic roll-forward’ mechanism — because after 1.0 Beta 1, any change to the AssemblyVersion was a breaking change for your customers, there was then nowhere to safely store your build number. AssemblyFileVersion is that safe haven, since it’s never automatically examined by the CLR. Maybe it’s clearer that way, having two separate version numbers, with separate meanings, rather than trying to make that separation between the Major/Minor (breaking) and the Build/Revision (non-breaking) parts of the AssemblyVersion.

The bottom line: Think carefully about when you change your AssemblyVersion

The moral is that if you’re shipping assemblies that other developers are going to be referencing, you need to be extremely careful about when you do (and don’t) change the AssemblyVersion of those assemblies. Any changes to the AssemblyVersion will mean that application developers will either have to re-compile against the new version (to update those AssemblyRef entries) or use assembly binding redirects to manually override the binding.

• Do not change the AssemblyVersion for a servicing release which is intended to be backwards compatible.
• Do change the AssemblyVersion for a release that you know has breaking changes.

Just take another look at the version attributes on mscorlib:

// Assembly mscorlib, Version 2.0.0.0
[assembly: AssemblyFileVersion("2.0.50727.3521")]
[assembly: AssemblyInformationalVersion("2.0.50727.3521")]
[assembly: AssemblyVersion("2.0.0.0")]

Note that it’s the AssemblyFileVersion that contains all the interesting servicing information (it’s the Revision part of this version that tells you what Service Pack you’re on), meanwhile the AssemblyVersion is fixed at a boring old 2.0.0.0. Any change to the AssemblyVersion would force every .NET application referencing mscorlib.dll to re-compile against the new version!

Drop the spaces around the = sign:

#!/bin/bash 
STR="Hello World" 
echo $STR 

Changing

RestResponse response = client.Execute(request);

to

IRestResponse response = client.Execute(request);

worked for me.

I think it is telling you exactly what is wrong. You cannot compare an integer with a varchar. PostgreSQL is strict and does not do any magic typecasting for you. I'm guessing SQLServer does typecasting automagically (which is a bad thing).

If you want to compare these two different beasts, you will have to cast one to the other using the casting syntax ::.

Something along these lines:

create view view1
as 
select table1.col1,table2.col1,table3.col3
from table1 
inner join
table2 
inner join 
table3
on 
table1.col4::varchar = table2.col5
/* Here col4 of table1 is of "integer" type and col5 of table2 is of type "varchar" */
/* ERROR: operator does not exist: integer = character varying */
....;

Notice the varchar typecasting on the table1.col4.

Also note that typecasting might possibly render your index on that column unusable and has a performance penalty, which is pretty bad. An even better solution would be to see if you can permanently change one of the two column types to match the other one. Literately change your database design.

Or you could create a index on the casted values by using a custom, immutable function which casts the values on the column. But this too may prove suboptimal (but better than live casting).

My answer may be outdated but hopefully it can be useful for someone.

1. In your Eclipse go to Window > Preferences > General > Network Connections > SSH2 (or just type "SSH2" in preferences window filter box).

2. In "Key Management" tab press "Generate RSA Key..." button. Optionally you can add comment (usually e-mail address) and passphrase to your key. Passphrase will be used during authentication on GitHub.

3. Copy your generated public key (in a box just below "Generate RSA Key..." button) and add it to your GitHub account.
4. Press "Save Private Key..." button to save your private RSA key into file. By default keys are stored in SSH2 home directory (see "General" tab).

That's it! Now you should be able to push your code to GitHub repo.

I also don't under stand what the "-" means after the 200 140 section of the log

That value corresponds to the referer as described by Joachim. If you see a dash though, that means that there was no referer value to begin with (eg. the user went straight to a specific destination, like if he/she typed a URL in their browser)

Most answers to this question use expensive operations like continuous insertions and deletions of items in an array, or copying arrays reiteratively.

Instead, this is the typical backtracking solution:

function permute(arr) {
  var results = [],
      l = arr.length,
      used = Array(l), // Array of bools. Keeps track of used items
      data = Array(l); // Stores items of the current permutation
  (function backtracking(pos) {
    if(pos == l) return results.push(data.slice());
    for(var i=0; i<l; ++i) if(!used[i]) { // Iterate unused items
      used[i] = true;      // Mark item as used
      data[pos] = arr[i];  // Assign item at the current position
      backtracking(pos+1); // Recursive call
      used[i] = false;     // Mark item as not used
    }
  })(0);
  return results;
}

permute([1,2,3,4]); // [  [1,2,3,4], [1,2,4,3], /* ... , */ [4,3,2,1]  ]

Since the results array will be huge, it might be a good idea to iterate the results one by one instead of allocating all the data simultaneously. In ES6, this can be done with generators:

function permute(arr) {
  var l = arr.length,
      used = Array(l),
      data = Array(l);
  return function* backtracking(pos) {
    if(pos == l) yield data.slice();
    else for(var i=0; i<l; ++i) if(!used[i]) {
      used[i] = true;
      data[pos] = arr[i];
      yield* backtracking(pos+1);
      used[i] = false;
    }
  }(0);
}

var p = permute([1,2,3,4]);
p.next(); // {value: [1,2,3,4], done: false}
p.next(); // {value: [1,2,4,3], done: false}
// ...
p.next(); // {value: [4,3,2,1], done: false}
p.next(); // {value: undefined, done: true}

Since I found that the above approved answer lacks some clarity and the op provides an incorrect solution that he/she will use. I therefore hope that the below example will help others. The solution is more or less portable as well.

Seems that there's enough variation that people go out of their way to allow conversion from all conventions to others: http://www.cowtowncoder.com/blog/archives/cat_json.html

Notably, the mentioned Jackson JSON parser prefers bean_naming.

The DateTime class takes a string in the constructor. If you prefix the timestamp with a @-character you create a DateTime object with the timestamp. For formating use the 'c' format ... a predefined ISO 8601 compound format.

If could use the DateTime class like this ... set the right timezone or leave it out if you want a UTC time.

$dt = new DateTime('@1333699439');
$dt->setTimezone(new DateTimeZone('America/New_York'));
echo $dt->format('c');

You are just creating your array incorrectly. You could use http_build_query:

$fields = array(
            'username' => "annonymous",
            'api_key' => urlencode("1234"),
            'images' => array(
                 urlencode(base64_encode('image1')),
                 urlencode(base64_encode('image2'))
            )
        );
$fields_string = http_build_query($fields);

So, the entire code that you could use would be:

<?php
//extract data from the post
extract($_POST);

//set POST variables
$url = 'http://api.example.com/api';
$fields = array(
            'username' => "annonymous",
            'api_key' => urlencode("1234"),
            'images' => array(
                 urlencode(base64_encode('image1')),
                 urlencode(base64_encode('image2'))
            )
        );

//url-ify the data for the POST
$fields_string = http_build_query($fields);

//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);

//execute post
$result = curl_exec($ch);
echo $result;

//close connection

You can loop through all the Animals using foreach and put it into NewAnimals.

I achieved 1600k concurrent idle socket connections, and at the same time 57k req/s on a Linux desktop (16G RAM, I7 2600 CPU). It's a single thread http server written in C with epoll. Source code is on github, a blog here.

Edit:

I did 600k concurrent HTTP connections (client & server) on both the same computer, with JAVA/Clojure . detail info post, HN discussion: http://news.ycombinator.com/item?id=5127251

The cost of a connection(with epoll):

• application need some RAM per connection
• TCP buffer 2 * 4k ~ 10k, or more
• epoll need some memory for a file descriptor, from epoll(7)

Each registered file descriptor costs roughly 90 bytes on a 32-bit kernel, and roughly 160 bytes on a 64-bit kernel.

My current setup (on MVC3, but I think it still applies) relies on having an ErrorController, so I use:

<system.web>
    <customErrors mode="On" defaultRedirect="~/Error">
      <error redirect="~/Error/NotFound" statusCode="404" />
    </customErrors>
</system.web>

And the controller contains the following:

public class ErrorController : Controller
{
    public ViewResult Index()
    {
        return View("Error");
    }
    public ViewResult NotFound()
    {
        Response.StatusCode = 404;  //you may want to set this to 200
        return View("NotFound");
    }
}

And the views just the way you implement them. I tend to add a bit of logic though, to show the stack trace and error information if the application is in debug mode. So Error.cshtml looks something like this:

@model System.Web.Mvc.HandleErrorInfo
@{
    Layout = "_Layout.cshtml";
    ViewBag.Title = "Error";
}
<div class="list-header clearfix">
    <span>Error</span>
</div>
<div class="list-sfs-holder">
    <div class="alert alert-error">
        An unexpected error has occurred. Please contact the system administrator.
    </div>
    @if (Model != null && HttpContext.Current.IsDebuggingEnabled)
    {
        <div>
            <p>
                <b>Exception:</b> @Model.Exception.Message<br />
                <b>Controller:</b> @Model.ControllerName<br />
                <b>Action:</b> @Model.ActionName
            </p>
            <div style="overflow:scroll">
                <pre>
                    @Model.Exception.StackTrace
                </pre>
            </div>
        </div>
    }
</div>

Very simple implementation (only basic functionality) based on CSS and one line of JavaScript code.

.dropdown {
  position: relative;
  width: 200px;
}

.dropdown select {
  width: 100%;
}

.dropdown > * {
  box-sizing: border-box;
  height: 1.5em;
}

.dropdown input {
  position: absolute;
  width: calc(100% - 20px);
}

<div class="dropdown">
  <input type="text" />
  <select  onchange="this.previousElementSibling.value=this.value; this.previousElementSibling.focus()">
    <option>This is option 1</option>
    <option>Option 2</option>
  </select>
</div>

Please note: it uses previousElementSibling() which is not supported in older browsers (below IE9)

Well, as Trufa has already shown, there are basically two ways of replacing a tuple's element at a given index. Either convert the tuple to a list, replace the element and convert back, or construct a new tuple by concatenation.

In [1]: def replace_at_index1(tup, ix, val):
   ...:     lst = list(tup)
   ...:     lst[ix] = val
   ...:     return tuple(lst)
   ...:

In [2]: def replace_at_index2(tup, ix, val):
   ...:     return tup[:ix] + (val,) + tup[ix+1:]
   ...:

So, which method is better, that is, faster?

It turns out that for short tuples (on Python 3.3), concatenation is actually faster!

In [3]: d = tuple(range(10))

In [4]: %timeit replace_at_index1(d, 5, 99)
1000000 loops, best of 3: 872 ns per loop

In [5]: %timeit replace_at_index2(d, 5, 99)
1000000 loops, best of 3: 642 ns per loop

Yet if we look at longer tuples, list conversion is the way to go:

In [6]: k = tuple(range(1000))

In [7]: %timeit replace_at_index1(k, 500, 99)
100000 loops, best of 3: 9.08 µs per loop

In [8]: %timeit replace_at_index2(k, 500, 99)
100000 loops, best of 3: 10.1 µs per loop

For very long tuples, list conversion is substantially better!

In [9]: m = tuple(range(1000000))

In [10]: %timeit replace_at_index1(m, 500000, 99)
10 loops, best of 3: 26.6 ms per loop

In [11]: %timeit replace_at_index2(m, 500000, 99)
10 loops, best of 3: 35.9 ms per loop

Also, performance of the concatenation method depends on the index at which we replace the element. For the list method, the index is irrelevant.

In [12]: %timeit replace_at_index1(m, 900000, 99)
10 loops, best of 3: 26.6 ms per loop

In [13]: %timeit replace_at_index2(m, 900000, 99)
10 loops, best of 3: 49.2 ms per loop

So: If your tuple is short, slice and concatenate. If it's long, do the list conversion!

With jQuery:

$('form').submit(function () {
    // Validate here

    if (pass)
        return true;
    else
        return false;
});

ser.read(64) should be ser.read(size=64); ser.read uses keyword arguments, not positional.

Also, you're reading from the port twice; what you probably want to do is this:

i=0
for modem in PortList:
    for port in modem:
        try:
            ser = serial.Serial(port, 9600, timeout=1)
            ser.close()
            ser.open()
            ser.write("ati")
            time.sleep(3)
            read_val = ser.read(size=64)
            print read_val
            if read_val is not '':
                print port
        except serial.SerialException:
            continue
        i+=1

You need the return so the true/false gets passed up to the form's submit event (which looks for this and prevents submission if it gets a false).

Lets look at some standard JS:

function testReturn() { return false; }

If you just call that within any other code (be it an onclick handler or in JS elsewhere) it will get back false, but you need to do something with that value.

...
testReturn()
...

In that example the return value is coming back, but nothing is happening with it. You're basically saying execute this function, and I don't care what it returns. In contrast if you do this:

...
var wasSuccessful = testReturn();
...

then you've done something with the return value.

The same applies to onclick handlers. If you just call the function without the return in the onsubmit, then you're saying "execute this, but don't prevent the event if it return false." It's a way of saying execute this code when the form is submitted, but don't let it stop the event.

Once you add the return, you're saying that what you're calling should determine if the event (submit) should continue.

This logic applies to many of the onXXXX events in HTML (onclick, onsubmit, onfocus, etc).

None of the other current answers will actually "merge" the files, as if you were using the merge command. (At best they'll require you to manually pick diffs.) If you actually want to take advantage of merging using the information from a common ancestor, you can follow a procedure based on one found in the "Advanced Merging" section of the git Reference Manual.

For this protocol, I'm assuming you're wanting to merge the file 'path/to/file.txt' from origin/master into HEAD - modify as appropriate. (You don't have to be in the top directory of your repository, but it helps.)

# Find the merge base SHA1 (the common ancestor) for the two commits:
git merge-base HEAD origin/master

# Get the contents of the files at each stage
git show <merge-base SHA1>:path/to/file.txt > ./file.common.txt
git show HEAD:path/to/file.txt > ./file.ours.txt
git show origin/master:path/to/file.txt > ./file.theirs.txt

# You can pre-edit any of the files (e.g. run a formatter on it), if you want.

# Merge the files
git merge-file -p ./file.ours.txt ./file.common.txt ./file.theirs.txt > ./file.merged.txt

# Resolve merge conflicts in ./file.merged.txt
# Copy the merged version to the destination
# Clean up the intermediate files

git merge-file should use all of your default merge settings for formatting and the like.

Also note that if your "ours" is the working copy version and you don't want to be overly cautious, you can operate directly on the file:

git merge-base HEAD origin/master
git show <merge-base SHA1>:path/to/file.txt > ./file.common.txt
git show origin/master:path/to/file.txt > ./file.theirs.txt
git merge-file path/to/file.txt ./file.common.txt ./file.theirs.txt

It works for me :).

div.parent {
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100vh;
}

Note that the if $myVar; then ... ;fi construct has a security problem you might want to avoid with

case $myvar in
  (true)    echo "is true";;
  (false)   echo "is false";;
  (rm -rf*) echo "I just dodged a bullet";;
esac

You might also want to rethink why if [ "$myvar" = "true" ] appears awkward to you. It's a shell string comparison that beats possibly forking a process just to obtain an exit status. A fork is a heavy and expensive operation, while a string comparison is dead cheap. Think a few CPU cycles versus several thousand. My case solution is also handled without forks.

That won't work if the string contains more than one match... try this:

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo "  $0) }'

or better (if the echo isn't a placeholder for something else):

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'

In your case you want to make a copy of the value before changing it:

echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'

Reflector and its add-in FileDisassembler.

Reflector will allow to see the source code. FileDisassembler will allow you to convert it into a VS solution.

THERE IS A BETTER WAY NOW!

As of Xcode 9.3 beta 4 you can use #if targetEnvironment(simulator) to check.

#if targetEnvironment(simulator)
//Your simulator code
#endif

UPDATE
Xcode 10 and iOS 12 SDK supports this too.

Goto to Tools > Preferences. In the tree, select Database > NLS. There are three Date/Time formats available: Date, Timestamp and Timestamp TZ. Editing the Date format gives the desired effect.

Like I have said above; this approach has not given me a permanent change.

You can move the count() inside your sub-select:

SELECT a AS current_a, COUNT(*) AS b,
   ( SELECT COUNT(*) FROM t WHERE a = current_a AND c = 'const' ) as d,
   from t group by a order by b desc

Sample text:

Clinton said
Bush used crayons
Reagan forgot

Just omitting a Bush match:

$ perl -ne 'print if /^(Clinton|Reagan)/' textfile
Clinton said
Reagan forgot

Or if you really want to specify:

$ perl -ne 'print if /^(?!Bush)(Clinton|Reagan)/' textfile
Clinton said
Reagan forgot

Just a sub answer: Absolutely use translated urls with a language identifier in front of them: http://www.domain.com/nl/over-ons
Hybride solutions tend to get complicated, so I would just stick with it. Why? Cause the url is essential for SEO.

About the db translation: Is the number of languages more or less fixed? Or rather unpredictable and dynamic? If it is fixed, I would just add new columns, otherwise go with multiple tables.

But generally, why not use Drupal? I know everybody wants to build their own CMS cause it's faster, leaner, etc. etc. But that is just really a bad idea!

$limit=5; // for exemple

$query = $this->getDoctrine()->getEntityManager()->createQuery(
           '// your request')

->setMaxResults($limit);

 $results = $query->getResult();

// Done

I don't know how good of a solution this is it, but after following some of the other answer to this question without success, i resolved setting the connection user of the service MSSQLSERVER to "Local Service".

N.B: i'm using SQL Server 2017.

robocopy src dst /MIR /XX

/XX : eXclude "eXtra" files and dirs (present in destination but not source). This will prevent any deletions from the destination. (this is the default)

string Index = i;
            string FileName = "Mutton" + Index + ".xml";
            XmlDocument xmlDoc = new XmlDocument();

            var path = Path.Combine(Server.MapPath("~/Content/FilesXML"), FileName);
            xmlDoc.Load(path); // Can use xmlDoc.LoadXml(YourString);

this is the best Solution to get the path what is exactly need for now

Java documentation is helpful to know the root cause of a particular IOException.

Just have a look at the direct known sub-interfaces of IOException from the documentation page:

ChangedCharSetException, CharacterCodingException, CharConversionException, ClosedChannelException, EOFException, FileLockInterruptionException, FileNotFoundException, FilerException, FileSystemException, HttpRetryException, IIOException, InterruptedByTimeoutException, InterruptedIOException, InvalidPropertiesFormatException, JMXProviderException, JMXServerErrorException, MalformedURLException, ObjectStreamException, ProtocolException, RemoteException, SaslException, SocketException, SSLException, SyncFailedException, UnknownHostException, UnknownServiceException, UnsupportedDataTypeException, UnsupportedEncodingException, UserPrincipalNotFoundException, UTFDataFormatException, ZipException

Most of these exceptions are self-explanatory.

A few IOExceptions with root causes:

EOFException: Signals that an end of file or end of stream has been reached unexpectedly during input. This exception is mainly used by data input streams to signal the end of the stream.

SocketException: Thrown to indicate that there is an error creating or accessing a Socket.

RemoteException: A RemoteException is the common superclass for a number of communication-related exceptions that may occur during the execution of a remote method call. Each method of a remote interface, an interface that extends java.rmi.Remote, must list RemoteException in its throws clause.

UnknownHostException: Thrown to indicate that the IP address of a host could not be determined (you may not be connected to Internet).

MalformedURLException: Thrown to indicate that a malformed URL has occurred. Either no legal protocol could be found in a specification string or the string could not be parsed.

var str = document.getElementById('mydiv').innerHTML;
document.getElementById('mytextarea').innerHTML = str.replace(/<br\s*[\/]?>/gi, "\n");

or using jQuery:

var str = $("#mydiv").html();
var regex = /<br\s*[\/]?>/gi;
$("#mydiv").html(str.replace(regex, "\n"));

example

edit: added i flag

edit2: you can use /<br[^>]*>/gi which will match anything between the br and slash if you have for example <br class="clear" />

First off, you should use dataUsingEncoding: instead of going through UTF8String. You only use UTF8String when you need a C string in that encoding.

Then, for UTF-16, just pass NSUnicodeStringEncoding instead of NSUTF8StringEncoding in your dataUsingEncoding: message.

These snippets all perform exactly the same thing:

element.on('click', function () { ... });
element.bind('click', function () { ... });
element.click(function () { ... });

However, they are very different from these, which all perform the same thing:

element.on('click', 'selector', function () { ... });
element.delegate('click', 'selector', function () { ... });
$('selector').live('click', function () { ... });

The second set of event handlers use event delegation and will work for dynamically added elements. Event handlers that use delegation are also much more performant. The first set will not work for dynamically added elements, and are much worse for performance.

jQuery's on() function does not introduce any new functionality that did not already exist, it is just an attempt to standardize event handling in jQuery (you no longer have to decide between live, bind, or delegate).

When to use dt accessor

A common source of confusion revolves around when to use .year and when to use .dt.year.

The former is an attribute for pd.DatetimeIndex objects; the latter for pd.Series objects. Consider this dataframe:

df = pd.DataFrame({'Dates': pd.to_datetime(['2018-01-01', '2018-10-20', '2018-12-25'])},
                  index=pd.to_datetime(['2000-01-01', '2000-01-02', '2000-01-03']))

The definition of the series and index look similar, but the pd.DataFrame constructor converts them to different types:

type(df.index)     # pandas.tseries.index.DatetimeIndex
type(df['Dates'])  # pandas.core.series.Series

The DatetimeIndex object has a direct year attribute, while the Series object must use the dt accessor. Similarly for month:

df.index.month               # array([1, 1, 1])
df['Dates'].dt.month.values  # array([ 1, 10, 12], dtype=int64)

A subtle but important difference worth noting is that df.index.month gives a NumPy array, while df['Dates'].dt.month gives a Pandas series. Above, we use pd.Series.values to extract the NumPy array representation.

When there are multiple activities set as main and launcher with an intent filter in the manifest. Then first activity considers as Launcher activity, and android launch or open the first activity.

<category android:name="android.intent.category.LAUNCHER" />  

The above code makes an app icon available in the device menu, so if we declare 2 launcher activity in the manifest, there will be 2 app icons get created in the device app menu.

So there will be 2 app icons, on click of the first icon, first declared activity in manifest will be launch, and click of another second declared activity gets launch

Call sys.exit.

A new favorite for me is @SuppressWarnings("WeakerAccess") in IntelliJ, which keeps it from complaining when it thinks you should have a weaker access modifier than you are using. We have to have public access for some methods to support testing, and the @VisibleForTesting annotation doesn't prevent the warnings.

ETA: "Anonymous" commented, on the page @MattCampbell linked to, the following incredibly useful note:

You shouldn't need to use this list for the purpose you are describing. IntelliJ will add those SuppressWarnings for you automatically if you ask it to. It has been capable of doing this for as many releases back as I remember.

Just go to the location where you have the warning and type Alt-Enter (or select it in the Inspections list if you are seeing it there). When the menu comes up, showing the warning and offering to fix it for you (e.g. if the warning is "Method may be static" then "make static" is IntellJ's offer to fix it for you), instead of selecting "enter", just use the right arrow button to access the submenu, which will have options like "Edit inspection profile setting" and so forth. At the bottom of this list will be options like "Suppress all inspections for class", "Suppress for class", "Suppress for method", and occasionally "Suppress for statement". You probably want whichever one of these appears last on the list. Selecting one of these will add a @SuppressWarnings annotation (or comment in some cases) to your code suppressing the warning in question. You won't need to guess at which annotation to add, because IntelliJ will choose based on the warning you selected.

For int 1-based components of a date:

var is_valid_date = function(year, month, day) {
    var d = new Date(year, month - 1, day);
    return d.getFullYear() === year && (d.getMonth() + 1) === month && d.getDate() === day
};

Tests:

    is_valid_date(2013, 02, 28)
&&  is_valid_date(2016, 02, 29)
&& !is_valid_date(2013, 02, 29)
&& !is_valid_date(0000, 00, 00)

This is short, yet efficient and proven approach:

location ~ (patternOne|patternTwo){ #rules etc. }

So one can easily have multiple patterns with simple pipe syntax pointing to the same location block / rules.

Try below code:

alert.setTitle(R.string.WtsOnYourMind);

 final EditText input = new EditText(context);
 input.setHeight(100);
 input.setWidth(340);
 input.setGravity(Gravity.LEFT);

 input.setImeOptions(EditorInfo.IME_ACTION_DONE);
 alert.setView(input);

Use @Input to pass your data to child components and then use ngOnChanges (https://angular.io/api/core/OnChanges) to see if that @Input changed on the fly.

You should use DrawEllipse:

//
// Summary:
//     Draws an ellipse defined by a bounding rectangle specified by coordinates
//     for the upper-left corner of the rectangle, a height, and a width.
//
// Parameters:
//   pen:
//     System.Drawing.Pen that determines the color, width,
//      and style of the ellipse.
//
//   x:
//     The x-coordinate of the upper-left corner of the bounding rectangle that
//     defines the ellipse.
//
//   y:
//     The y-coordinate of the upper-left corner of the bounding rectangle that
//     defines the ellipse.
//
//   width:
//     Width of the bounding rectangle that defines the ellipse.
//
//   height:
//     Height of the bounding rectangle that defines the ellipse.
//
// Exceptions:
//   System.ArgumentNullException:
//     pen is null.
public void DrawEllipse(Pen pen, int x, int y, int width, int height);

Instead of using the placeholder text, you'll want to set the actual text property of the field to MM/YYYY, set the delegate of the text field and listen for this method:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {     // update the text of the label } 

Inside that method, you can figure out what the user has typed as they type, which will allow you to update the label accordingly.

There is a much easier way than everything above and this approach does not require the use of android.permission.GET_TASKS in the manifest, or have the issue of race conditions or memory leaks pointed out in the accepted answer.

1. Make a STATIC variable in the main Activity. Static allows other activities to receive the data from another activity. onPause() set this variable false, onResume and onCreate() set this variable true.

   private static boolean mainActivityIsOpen;
   

2. Assign getters and setters of this variable.

   public static boolean mainActivityIsOpen() {
       return mainActivityIsOpen;
   }
   
   public static void mainActivityIsOpen(boolean mainActivityIsOpen) {
       DayView.mainActivityIsOpen = mainActivityIsOpen;
   }
   

3. And then from another activity or Service

   if (MainActivity.mainActivityIsOpen() == false)
   {
                   //do something
   }
   else if(MainActivity.mainActivityIsOpen() == true)
   {//or just else. . . ( or else if, does't matter)
           //do something
   }
