adapted from MSDN, how to left join using EF 4

var query = from u in usergroups
            join p in UsergroupPrices on u.UsergroupID equals p.UsergroupID into gj
            from x in gj.DefaultIfEmpty()
            select new { 
                UsergroupID = u.UsergroupID,
                UsergroupName = u.UsergroupName,
                Price = (x == null ? String.Empty : x.Price) 
            };

margin: all_four_margin

by providing 50% to all_four_margin will place the element at the center

style="margin: 50%"

you can apply it for following too

margin: top right bottom left

margin: top right&left bottom

margin: top&bottom right&left

by giving appropriate % we get the element wherever we want.

The question mark is used to define wildcards. Checkout the Oracle documentation about them: http://docs.oracle.com/javase/tutorial/java/generics/wildcards.html

The difference is that the uint and ulong are unsigned data types, meaning the range is different: They do not accept negative values:

int range: -2,147,483,648 to 2,147,483,647
uint range: 0 to 4,294,967,295

long range: –9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
ulong range: 0 to 18,446,744,073,709,551,615

Selection Sort: As you start building the sorted sublist, the algorithm ensures that the sorted sublist is always completely sorted, not only in terms of it's own elements but also in terms of the complete array i.e. both sorted and unsorted sublist. Thus the new smallest element once found from the unsorted sublist would just be appended at the end of the sorted sublist.

Insertion Sort: The algorithm again divide the array into two part, but here the element is picked from second part and inserted at correct position to the first part. This never guarantees that the first part is sorted in terms of the complete array, though ofcourse in the final pass every element is at its correct sorted position.

d = {'A': 4,'B':10}

min_v = min(zip(d.values(), d.keys()))
# min_v is (4,'A')

max_v = max(zip(d.values(), d.keys()))
# max_v is (10,'B')

As said, numpy.empty() is the way to go. However, for objects, fill() might not do exactly what you think it does:

In[36]: a = numpy.empty(5,dtype=object)
In[37]: a.fill([])
In[38]: a
Out[38]: array([[], [], [], [], []], dtype=object)
In[39]: a[0].append(4)
In[40]: a
Out[40]: array([[4], [4], [4], [4], [4]], dtype=object)

One way around can be e.g.:

In[41]: a = numpy.empty(5,dtype=object)
In[42]: a[:]= [ [] for x in range(5)]
In[43]: a[0].append(4)
In[44]: a
Out[44]: array([[4], [], [], [], []], dtype=object)

Take a look at UrlRewriteFilter which is essentially a java-based implementation of Apache's mod_rewrite.

You'll need to extract it into ROOT folder under your Tomcat's webapps folder; you can then configure redirects to any other context within its WEB-INF/urlrewrite.xml configuration file.

You could simply use echo on and you will see that goto :eof or even exit /b doesn't work as expected.

The code inside of the loop isn't executed anymore, but the loop is expanded for all numbers to the end.
That's why it's so slow.

The only way to exit a FOR /L loop seems to be the variant of exit like the exsample of Wimmel, but this isn't very fast nor useful to access any results from the loop.

This shows 10 expansions, but none of them will be executed

echo on
for /l %%n in (1,1,10) do (
  goto :eof
  echo %%n
)

Use the web browser control. This requires Adobe reader to be installed but most likely you have it anyway. Set the UrL of the control to the file location.

You can use the to_pydatetime method to be more explicit:

In [11]: ts = pd.Timestamp('2014-01-23 00:00:00', tz=None)

In [12]: ts.to_pydatetime()
Out[12]: datetime.datetime(2014, 1, 23, 0, 0)

It's also available on a DatetimeIndex:

In [13]: rng = pd.date_range('1/10/2011', periods=3, freq='D')

In [14]: rng.to_pydatetime()
Out[14]:
array([datetime.datetime(2011, 1, 10, 0, 0),
       datetime.datetime(2011, 1, 11, 0, 0),
       datetime.datetime(2011, 1, 12, 0, 0)], dtype=object)

I think you haven't messed up yet. Try:

git reset HEAD^

This will bring the dir to state before you've made the commit, HEAD^ means the parent of the current commit (the one you don't want anymore), while keeping changes from it (unstaged).

git log --oneline | grep PATTERN

It sets the distance of the inset between the content view and the enclosing scroll view.

Obj-C

aScrollView.contentInset = UIEdgeInsetsMake(0, 0, 0, 7.0);

Swift 5.0

aScrollView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 7.0)

Here's a good iOS Reference Library article on scroll views that has an informative screenshot (fig 1-3) - I'll replicate it via text here:

  _|?_cW_?_|_?_
   |       | 
---------------
   |content| ?
 ? |content| contentInset.top
cH |content|
 ? |content| contentInset.bottom
   |content| ?
---------------
  _|_______|___ 
             ?


   (cH = contentSize.height; cW = contentSize.width)

The scroll view encloses the content view plus whatever padding is provided by the specified content insets.

I think you need str.contains, if you need rows where values of column date contains string 07311954:

print df[df['date'].astype(str).str.contains('07311954')]

Or if type of date column is string:

print df[df['date'].str.contains('07311954')]

If you want check last 4 digits for string 1954 in column date:

print df[df['date'].astype(str).str[-4:].str.contains('1954')]

Sample:

print df['date']
0    8152007
1    9262007
2    7311954
3    2252011
4    2012011
5    2012011
6    2222011
7    2282011
Name: date, dtype: int64

print df['date'].astype(str).str[-4:].str.contains('1954')
0    False
1    False
2     True
3    False
4    False
5    False
6    False
7    False
Name: date, dtype: bool

print df[df['date'].astype(str).str[-4:].str.contains('1954')]

Update: The code in this answer is for Super CSV 1.52. Updated code examples for Super CSV 2.4.0 can be found at the project website: http://super-csv.github.io/super-csv/index.html

The SuperCSV project directly supports the parsing and structured manipulation of CSV cells. From http://super-csv.github.io/super-csv/examples_reading.html you'll find e.g.

given a class

public class UserBean {
    String username, password, street, town;
    int zip;

    public String getPassword() { return password; }
    public String getStreet() { return street; }
    public String getTown() { return town; }
    public String getUsername() { return username; }
    public int getZip() { return zip; }
    public void setPassword(String password) { this.password = password; }
    public void setStreet(String street) { this.street = street; }
    public void setTown(String town) { this.town = town; }
    public void setUsername(String username) { this.username = username; }
    public void setZip(int zip) { this.zip = zip; }
}

and that you have a CSV file with a header. Let's assume the following content

username, password,   date,        zip,  town
Klaus,    qwexyKiks,  17/1/2007,   1111, New York
Oufu,     bobilop,    10/10/2007,  4555, New York

You can then create an instance of the UserBean and populate it with values from the second line of the file with the following code

class ReadingObjects {
  public static void main(String[] args) throws Exception{
    ICsvBeanReader inFile = new CsvBeanReader(new FileReader("foo.csv"), CsvPreference.EXCEL_PREFERENCE);
    try {
      final String[] header = inFile.getCSVHeader(true);
      UserBean user;
      while( (user = inFile.read(UserBean.class, header, processors)) != null) {
        System.out.println(user.getZip());
      }
    } finally {
      inFile.close();
    }
  }
}

using the following "manipulation specification"

final CellProcessor[] processors = new CellProcessor[] {
    new Unique(new StrMinMax(5, 20)),
    new StrMinMax(8, 35),
    new ParseDate("dd/MM/yyyy"),
    new Optional(new ParseInt()),
    null
};

You are looking for child_process.exec

Here is the example:

const exec = require('child_process').exec;
const child = exec('cat *.js bad_file | wc -l',
    (error, stdout, stderr) => {
        console.log(`stdout: ${stdout}`);
        console.log(`stderr: ${stderr}`);
        if (error !== null) {
            console.log(`exec error: ${error}`);
        }
});

So for me and my pals working on a Node.js app (with Postgres and Sequelize), we had to

1. brew install postgresql (one of us was missing postgres, one of us was not, and yet we were getting the same error msg as listed above)

2. brew services start postgresql **** (utilize Homebrew to start postgres)

3. createdb <name of database in config.json file>

4. node_modules/.bin/sequelize db:migrate

5. npm start

In my case I have imported the RouterModule in App module but not imported in my feature module. After import the router module in my EventModule the error goes away.

    import {NgModule } from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    import {EventListComponent} from './EventList.Component';
    import {EventThumbnailComponent} from './EventThumbnail.Component';
    import { EventService } from './shared/Event.Service'
    import {ToastrService} from '../shared/toastr.service';
    import {EventDetailsComponent} from './event-details/event.details.component';
    import { RouterModule } from "@angular/router";
    @NgModule({
      imports:[BrowserModule,RouterModule],
      declarations:[EventThumbnailComponent,EventListComponent,EventDetailsComponent],
      exports: [EventThumbnailComponent,EventListComponent,EventDetailsComponent],
       providers: [EventService,ToastrService]
    })
    export class EventModule {
        
     }

I faced this problem this morning when I just opened an old app with a different certificate and allowed its access to the keychain. My other app that was working pretty well, stopped working with this error. I've been pulling out my hair till now, when I simply did this:

Xcode Menu > Preferences > Accounts > THE_APPLE_ID_THAT_YOU_ARE_USING > View Details

In the new window, at the bottom left of the Signing identities press the + button and select iOS Development. It'll re-add the identity, and after that my problem is fixed now and the app is running on the device again.

Have your tried using the 'return' keyword?

def rps():
    return True

Top of The Android Studio Title bar its shows the complete file path or LocationLook this image

Go to Build Settings tab, and then change the Product Bundle Identifier to another name. It works in mine.

Currently it only works for the .dropdown-menu:

.dropdown-menu .divider {
  height: 1px;
  margin: 9px 0;
  overflow: hidden;
  background-color: #e5e5e5;
}

If you want it for other use, in your own css, following the bootstrap.css create another one:

.divider {
  height: 1px;
  width:100%;
  display:block; /* for use on default inline elements like span */
  margin: 9px 0;
  overflow: hidden;
  background-color: #e5e5e5;
}

Another way to do simultaneous animations if you want to call them separately (eg. from different code) is to use queue. Again, as with Tinister's answer you would have to use animate for this and not fadeIn:

$('.tooltip').css('opacity', 0);
$('.tooltip').show();
...

$('.tooltip').animate({opacity: 1}, {queue: false, duration: 'slow'});
$('.tooltip').animate({ top: "-10px" }, 'slow');

Try

    UPDATE products SET former_date=20111218131717 WHERE id=1

Alternatively, you might want to look at using the STR_TO_DATE (see STR_TO_DATE(str,format)) function.

An iframe is universally handled like a different HTML page by most browsers. If you want to apply the same stylesheet to the content of the iframe, just reference it from the pages used in there.

As other people have commented, because the return type of your method is String Spring won't feel need to do anything with the result.

If you change your signature so that the return type is something that needs marshalling, that should help:

@RequestMapping(value = "/json", method = RequestMethod.GET, produces = "application/json")
@ResponseBody
public Map<String, Object> bar() {
    HashMap<String, Object> map = new HashMap<String, Object>();
    map.put("test", "jsonRestExample");
    return map;
}

GetHashCode() is used to help support using the object as a key for hash tables. (A similar thing exists in Java etc). The goal is for every object to return a distinct hash code, but this often can't be absolutely guaranteed. It is required though that two logically equal objects return the same hash code.

A typical hash table implementation starts with the hashCode value, takes a modulus (thus constraining the value within a range) and uses it as an index to an array of "buckets".

I literally just wanted the first row of my data which are the headers I need and didn't want to iterate over all my data to get them, so I just did this:

with open(data, 'r', newline='') as csvfile:
t = 0
for i in csv.reader(csvfile, delimiter=',', quotechar='|'):
    if t > 0:
        break
    else:
        dbh = i
        t += 1

typeof foo === "undefined" is different from foo === undefined, never confuse them. typeof foo === "undefined" is what you really need. Also, use !== in place of !=

So the statement can be written as

function (data) {
  if (typeof data !== "undefined" && data !== null) {
    // some code here
  }
}

Edit:

You can not use foo === undefined for undeclared variables.

var t1;

if(typeof t1 === "undefined")
{
  alert("cp1");
}

if(t1 === undefined)
{
  alert("cp2");
}

if(typeof t2 === "undefined")
{
  alert("cp3");
}

if(t2 === undefined) // fails as t2 is never declared
{
  alert("cp4");
}

Try this for Windows:

    npm uninstall -g cordova

Try this for MAC:

    sudo npm uninstall -g cordova

You can also add Cordova like this:

1. If You Want To install the previous version of Cordova through the Node Package Manager (npm):

   npm install -g [email protected]
   

2. If You Want To install the latest version of Cordova:

   npm install -g cordova 
   

Enjoy!

Json.Net prefers to use the default (parameterless) constructor on an object if there is one. If there are multiple constructors and you want Json.Net to use a non-default one, then you can add the [JsonConstructor] attribute to the constructor that you want Json.Net to call.

[JsonConstructor]
public Result(int? code, string format, Dictionary<string, string> details = null)
{
    ...
}

It is important that the constructor parameter names match the corresponding property names of the JSON object (ignoring case) for this to work correctly. You do not necessarily have to have a constructor parameter for every property of the object, however. For those JSON object properties that are not covered by the constructor parameters, Json.Net will try to use the public property accessors (or properties/fields marked with [JsonProperty]) to populate the object after constructing it.

If you do not want to add attributes to your class or don't otherwise control the source code for the class you are trying to deserialize, then another alternative is to create a custom JsonConverter to instantiate and populate your object. For example:

class ResultConverter : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        return (objectType == typeof(Result));
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        // Load the JSON for the Result into a JObject
        JObject jo = JObject.Load(reader);

        // Read the properties which will be used as constructor parameters
        int? code = (int?)jo["Code"];
        string format = (string)jo["Format"];

        // Construct the Result object using the non-default constructor
        Result result = new Result(code, format);

        // (If anything else needs to be populated on the result object, do that here)

        // Return the result
        return result;
    }

    public override bool CanWrite
    {
        get { return false; }
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }
}

Then, add the converter to your serializer settings, and use the settings when you deserialize:

JsonSerializerSettings settings = new JsonSerializerSettings();
settings.Converters.Add(new ResultConverter());
Result result = JsonConvert.DeserializeObject<Result>(jsontext, settings);

(Your question is still unclear on whether your code is calling printStackTrace() or this is being done by a logging handler.)

Here are some possible explanations about what might be happening:

• The logger / handler being used has been configured to only output the exception's message string, not a full stack trace.

• Your application (or some third-party library) is logging the exception using LOG.error(ex); rather than the 2-argument form of (for example) the log4j Logger method.

• The message is coming from somewhere different to where you think it is; e.g. it is actually coming some third-party library method, or some random stuff left over from earlier attempts to debug.

• The exception that is being logged has overloaded some methods to obscure the stacktrace. If that is the case, the exception won't be a genuine NullPointerException, but will be some custom subtype of NPE or even some unconnected exception.

I think that the last possible explanation is pretty unlikely, but people do at least contemplate doing this kind of thing to "prevent" reverse engineering. Of course it only really succeeds in making life difficult for honest developers.

Classification- A data-set can have different groups/ classes. red, green and black. Classification will try to find rules that divides them in different classes.

Custering- if a data-set is not having any class and you want to put them in some class/grouping, you do clustering. The purple circles above.

If classification rules are not good, you will have mis-classification in testing or ur rules are not correct enough.
if clustering is not good, you will have lot of outliers ie. data points not able to fall in any cluster.

The Javadoc generation can be skipped by setting the property maven.javadoc.skip to true [1], i.e.

-Dmaven.javadoc.skip=true

(and not false)

I would say that using:

* {
  margin: 0;
  padding: 0;
}

is a bad way of solving this.

The reason for the h1 margin popping out of the parent is that the parent does not have a padding.

If you add a padding to the parent element of the h1, the margin will be inside the parent.

Resetting all paddings and margins to 0 can cause a lot of side effects. Then it's better to remove margin-top for this specific headline.

This might be super late, but this is for people that might stumble on this problem and might want to use external package for parsing date string.

I've tried looking for a libraries and I found this one:

Looks like you're already using request module.

in this case all you need to post multipart/form-data is to use its form feature:

var req = request.post(url, function (err, resp, body) {
  if (err) {
    console.log('Error!');
  } else {
    console.log('URL: ' + body);
  }
});
var form = req.form();
form.append('file', '<FILE_DATA>', {
  filename: 'myfile.txt',
  contentType: 'text/plain'
});

but if you want to post some existing file from your file system, then you may simply pass it as a readable stream:

form.append('file', fs.createReadStream(filepath));

request will extract all related metadata by itself.

For more information on posting multipart/form-data see node-form-data module, which is internally used by request.

I got same problem trying to compile "clean install" using a Lowend 512Mb ram VPS and good CPU. Run OutOfMemory and killed script repeatly.

I used export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=350m" and worked.

Still getting some other compiling failure because is the first time i need Maven, but OutOfMemory problem has gone.

Give the name to both of the buttons and Get the check the value from form.

<div>
   <input name="submitButton" type="submit" value="Register" />
</div>

<div>
   <input name="cancelButton" type="submit" value="Cancel" />
</div>

On controller side :

public ActionResult Save(FormCollection form)
{
 if (this.httpContext.Request.Form["cancelButton"] !=null)
 {
   // return to the action;
 }

else if(this.httpContext.Request.Form["submitButton"] !=null)
 {
   // save the oprtation and retrun to the action;
 }
}

Put Scripts at the Bottom

The problem caused by scripts is that they block parallel downloads. The HTTP/1.1 specification suggests that browsers download no more than two components in parallel per hostname. If you serve your images from multiple hostnames, you can get more than two downloads to occur in parallel. While a script is downloading, however, the browser won't start any other downloads, even on different hostnames. In some situations it's not easy to move scripts to the bottom. If, for example, the script uses document.write to insert part of the page's content, it can't be moved lower in the page. There might also be scoping issues. In many cases, there are ways to workaround these situations.

An alternative suggestion that often comes up is to use deferred scripts. The DEFER attribute indicates that the script does not contain document.write, and is a clue to browsers that they can continue rendering. Unfortunately, Firefox doesn't support the DEFER attribute. In Internet Explorer, the script may be deferred, but not as much as desired. If a script can be deferred, it can also be moved to the bottom of the page. That will make your web pages load faster.

EDIT: Firefox does support the DEFER attribute since version 3.6.

To split a string with a delimiter with GNU sed you say:

sed 's/delimiter/\n/g'     # GNU sed

For example, to split using : as a delimiter:

$ sed 's/:/\n/g' <<< "he:llo:you"
he
llo
you

Or with a non-GNU sed:

$ sed $'s/:/\\\n/g' <<< "he:llo:you"
he
llo
you

In this particular case, you missed the g after the substitution. Hence, it is just done once. See:

$ echo "string1:string2:string3:string4:string5" | sed s/:/\\n/g
string1
string2
string3
string4
string5

g stands for global and means that the substitution has to be done globally, that is, for any occurrence. See that the default is 1 and if you put for example 2, it is done 2 times, etc.

All together, in your case you would need to use:

sed 's/:/\\n/g' ~/Desktop/myfile.txt

Note that you can directly use the sed ... file syntax, instead of unnecessary piping: cat file | sed.

First one is for Javadoc you define on the top of classes, interfaces, methods etc. You can use Javadoc as the name suggest to document your code on what the class does or what method does etc and generate report on it.

Second one is code block comment. Say for example you have some code block which you do not want compiler to interpret then you use code block comment.

another one is // this you use on statement level to specify what the proceeding lines of codes are supposed to do.

There are some other also like //TODO, this will mark that you want to do something later on that place

//FIXME you can use when you have some temporary solution but you want to visit later and make it better.

Hope this helps

Below is the Jquery way of populating a drop down list whose id is "FolderListDropDown"

$.getJSON("/Admin/GetFolderList/", function(result) {
    for (var i = 0; i < result.length; i++) {
        var elem = $("<option></option>");
        elem.attr("value", result[i].ImageFolderID);
        elem.text(result[i].Name);
        elem.appendTo($("select#FolderListDropDown"));
     }
});

In my case the issue was caused by the same name of target and folder inside a group.

Just rename conflicted file or folder to resolve the issue.

How about this (improved by Jake's suggestion):

:exe "!mv % newfilename" | e newfilename

This will work as well:

.clearfix:before,
.clearfix:after {
    content: "";
    display: table;
} 

.clearfix:after {
    clear: both;
}

/* IE 6 & 7 */
.clearfix {
    zoom: 1;
}

Give the class clearfix to the parent element, for example your ul element.

Sources here and here.

Add this to your css.

.highcharts-credits {
display: none !important;
}

Also internationalization.

I fooled around with this some a while back. Did this in my model:

[Display(Name = "XXX", ResourceType = typeof(Labels))]

I had a separate class library for all the resources, so I had Labels.resx, Labels.culture.resx, etc.

In there I had key = XXX, value = "meaningful string in that culture."

Simply type source ~/.bash_profile

Alternatively, if you like saving keystrokes you can type . ~/.bash_profile

please try with below query

select id,numbers_from,created_date,amount_numbers,SMS_text 
from Test_Table
where 
convert(datetime, convert(varchar(10), created_date, 102))  <= convert(datetime,'2013-04-12')

As of 2018-04-20 Git for Windows has a bug which effectively limits the file size to 4GB max using that particular implementation (this bug propagates to lfs as well).

Step 1: Create HTML Page where to place the HTML Code.

Step 2: In the HTML Code Page Bottom(footer)Create Javascript: and put Jquery Code in Script tag.

Step 3: Create PHP File and php code copy past. after Jquery Code in $.ajax Code url apply which one on your php file name.

JS

//$(document).on("change", "#avatar", function() {   // If you want to upload without a submit button 
$(document).on("click", "#upload", function() {
  var file_data = $("#avatar").prop("files")[0]; // Getting the properties of file from file field
  var form_data = new FormData(); // Creating object of FormData class
  form_data.append("file", file_data) // Appending parameter named file with properties of file_field to form_data
  form_data.append("user_id", 123) // Adding extra parameters to form_data
  $.ajax({
    url: "/upload_avatar", // Upload Script
    dataType: 'script',
    cache: false,
    contentType: false,
    processData: false,
    data: form_data, // Setting the data attribute of ajax with file_data
    type: 'post',
    success: function(data) {
      // Do something after Ajax completes 
    }
  });
});

HTML

<input id="avatar" type="file" name="avatar" />
<button id="upload" value="Upload" />

Php

print_r($_FILES);
print_r($_POST);

If you use jQuery built-in after() with empty value it will create a dynamic object that will match your :after CSS selector.

$('.active').after().click(function () {
    alert('clickable!');
});

See the jQuery documentation.

It seems that IDLE changes its current working dir to location of the script that is executed, while when running the script using cmd doesn't do that and it leaves CWD as it is.

To change current working dir to the one containing your script you can use:

import os
os.chdir(os.path.dirname(__file__))
print(os.getcwd())

The __file__ variable is available only if you execute script from file, and it contains path to the file. More on it here: Python __file__ attribute absolute or relative?

The -D properties will not be reliable propagated from the surefire-pluging to your test (I do not know why it works with eclipse). When using maven on the command line use the argLine property to wrap your property. This will pass them to your test

mvn -DargLine="-DWSNSHELL_HOME=conf" test

Use System.getProperty to read the value in your code. Have a look to this post about the difference of System.getenv and Sytem.getProperty.

My issue was different. This occurred after an unexpected shutdown of my windows 7 machine. I performed a clean solution and it ran as expected.

To add a bit more value to all the other answer's to this question, one should invest a few minutes in the question: What is the output of the following code?

#include <iostream>
void throw_exception() throw(const char *)
{
    throw 10;
}
void my_unexpected(){
    std::cout << "well - this was unexpected" << std::endl;
}
int main(int argc, char **argv){
    std::set_unexpected(my_unexpected);
    try{
        throw_exception();
    }catch(int x){
        std::cout << "catch int: " << x << std::endl;
    }catch(...){
        std::cout << "catch ..." << std::endl;
    }
}

Answer: As noted here, the program calls std::terminate() and thus none of the exception handlers will get called.

Details: First my_unexpected() function is called, but since it doesn't re-throw a matching exception type for the throw_exception() function prototype, in the end, std::terminate() is called. So the full output looks like this:

user@user:~/tmp$ g++ -o except.test except.test.cpp
user@user:~/tmp$ ./except.test
well - this was unexpected
terminate called after throwing an instance of 'int'
Aborted (core dumped)

To fix, open your script with vi or vim and enter in vi command mode (key Esc), then type this:

:set fileformat=unix

Finally save it

:x! or :wq!

You can do it setting the transparency via style right within the table tag:

<table id="Main table" style="background-color:rgba(0, 0, 0, 0);">

The last digit in the rgba function is for transparency. 1 means 100% opaque, while 0 stands for 100% transparent.

You can also use EXIT_SUCCESS instead of return 0;. The macro EXIT_SUCCESS is actually defined as zero, but makes your program more readable.

try this

DECLARE @StartTime DATETIME
SET @StartTime = GETDATE()

  SET @EndTime = GETDATE()
  PRINT 'StartTime = ' + CONVERT(VARCHAR(30),@StartTime,121)
  PRINT '  EndTime = ' + CONVERT(VARCHAR(30),@EndTime,121)
  PRINT ' Duration = ' + CONVERT(VARCHAR(30),@EndTime -@starttime,114)

If that doesn't do it, then try SET STATISTICS TIME ON

What you are saying is in conflict with what it says in the MSDN library at this location:

http://msdn.microsoft.com/en-us/library/system.runtime.serialization.datacontractserializer.aspx

I don't see any mention of the SP1 feature you mention.

if(target.matches("\\S")) 
    // then string contains at least one non-whitespace character

Note use of back-slash cap-S, meaning "non-whitespace char"

I'd wager this is the simplest (and perhaps the fastest?) solution.

git fetch
git branch --track branch-name origin/branch-name

First command makes sure you have remote branch in local repository. Second command creates local branch which tracks remote branch. It assumes that your remote name is origin and branch name is branch-name.

--track option is enabled by default for remote branches and you can omit it.

Install both JDK 64 bit 1.6 for Windows and JRE 1.7 64bit for Windows.

It worked in my case.

Google Drive folders can be embedded and displayed in list and grid views:

List view

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#list" style="width:100%; height:600px; border:0;"></iframe>

Grid view

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

Q: What is a folder ID (FOLDER-ID) and how can I get it?

A: Go to Google Drive >> open the folder >> look at its URL in the address bar of your browser. For example:

Folder URL: https://drive.google.com/drive/folders/0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2

Folder ID:
0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2

Caveat with folders requiring permission

This technique works best for folders with public access. Folders that are shared only with certain Google accounts will cause trouble when you embed them this way. At the time of this edit, a message "You need permission" appears, with some buttons to help you "Request access" or "Switch accounts" (or possibly sign-in to a Google account). The Javascript in these buttons doesn't work properly inside an IFRAME in Chrome.

Answer by Adamski is a good one and describes the steps in an encoding operation when using the general encode method (that takes a byte buffer as one of the inputs)

However, the method in question (in this discussion) is a variant of encode - encode(CharBuffer in). This is a convenience method that implements the entire encoding operation. (Please see java docs reference in P.S.)

As per the docs, This method should therefore not be invoked if an encoding operation is already in progress (which is what is happening in ZenBlender's code -- using static encoder/decoder in a multi threaded environment).

Personally, I like to use convenience methods (over the more general encode/decode methods) as they take away the burden by performing all the steps under the covers.

ZenBlender and Adamski have already suggested multiple ways options to safely do this in their comments. Listing them all here:

• Create a new encoder/decoder object when needed for each operation (not efficient as it could lead to a large number of objects). OR,
• Use a ThreadLocal to avoid creating new encoder/decoder for each operation. OR,
• Synchronize the entire encoding/decoding operation (this might not be preferred unless sacrificing some concurrency is ok for your program)

P.S.

java docs references:

1. Encode (convenience) method: http://docs.oracle.com/javase/6/docs/api/java/nio/charset/CharsetEncoder.html#encode%28java.nio.CharBuffer%29
2. General encode method: http://docs.oracle.com/javase/6/docs/api/java/nio/charset/CharsetEncoder.html#encode%28java.nio.CharBuffer,%20java.nio.ByteBuffer,%20boolean%29

You need to change the password directly in the database because at mysql the users and their profiles are saved in the database.

So there are several ways. At phpMyAdmin you simple go to user admin, choose root and change the password.

Perhaps you could use pandas.where(args) like so:

data_frame = data_frame.where(data_frame < 0, 0)

You can use native element divider.

Install it with:

npm install --save react-native-elements
# or with yarn
yarn add react-native-elements

import { Divider } from 'react-native-elements'

Then go with:

<Divider style={{ backgroundColor: 'blue' }} />

This one good also to view cachepage http://www.cachepage.net

1. Cache page view via google: webcache.googleusercontent.com/search?q=cache: Your url

2. Cache page view via archive.org: web.archive.org/web/*/Your url

You can do this too:

oldIFS="$IFS"
IFS=$'\n' arr=($(<file))
IFS="$oldIFS"
echo "${arr[1]}" # It will print `A Dog`.

Note:

Filename expansion still occurs. For example, if there's a line with a literal * it will expand to all the files in current folder. So use it only if your file is free of this kind of scenario.

If you don't want to deal with security and want to make it as exposed (aka "convenient") as possible for short term, and|or don't have ssh/telnet or key generation on all your hosts, you can can hack a one-liner together with netcat. Write a command to your target computer's port over the network and it will run it. Then you can block access to that port to a few "trusted" users or wrap it in a script that only allows certain commands to run. And use a low privilege user.

on the server

mkfifo /tmp/netfifo; nc -lk 4201 0</tmp/netfifo | bash -e &>/tmp/netfifo

This one liner reads whatever string you send into that port and pipes it into bash to be executed. stderr & stdout are dumped back into netfifo and sent back to the connecting host via nc.

on the client

To run a command remotely: echo "ls" | nc HOST 4201

use IDENTITY(1,1) while creating the table eg

CREATE TABLE SAMPLE(
[Id]     [int]  IDENTITY(1,1) NOT NULL,
[Status] [smallint] NOT NULL,

CONSTRAINT [PK_SAMPLE] PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)
)

This seems to be an efficient way to list vars with column number:

cbind(names(df)) 

Output:

     [,1]
[1,] "A" 
[2,] "B" 
[3,] "C" 

Sometimes I like to copy variables with position into my code so I use this function:

varnums<- function(x) {w=as.data.frame(c(1:length(colnames(x))),
          paste0('# ',colnames(x)))
names(w)= c("# Var/Pos")
w}
varnums(df)

Output:

# Var/Pos
# A         1
# B         2
# C         3

While there is still some truth to most of the answers above, I think they deserve an update:

Over the years the performance of SVG has improved a lot and now there is hardware-accelerated CSS transitions and animations for SVG that do not depend on JavaScript performance at all. Of course JavaScript performance has improved, too and with it the performance of Canvas, but not as much as SVG got improved. Also there is a "new kid" on the block that is available in almost all browsers today and that is WebGL. To use the same words that Simon used above: It beats both Canvas and SVG hands down. This doesn't mean it should be the go-to technology, though, since it's a beast to work with and it is only faster in very specific use-cases.

IMHO for most use-cases today, SVG gives the best performance/usability ratio. Visualizations need to be really complex (with respect to number of elements) and really simple at the same time (per element) so that Canvas and even more so WebGL really shine.

In this answer to a similar question I am providing more details, why I think that the combination of all three technologies sometimes is the best option you have.

try using the on error event of the client to find the issue.

var http = require('http');

var options = {
    host: 'google.com',
    path: '/'
}
var request = http.request(options, function (res) {
    var data = '';
    res.on('data', function (chunk) {
        data += chunk;
    });
    res.on('end', function () {
        console.log(data);

    });
});
request.on('error', function (e) {
    console.log(e.message);
});
request.end();

I have a same problem, with volley, but this is my solution:

1. In Android Manifiest, in tag application add:

   android:usesCleartextTraffic="true"
   android:networkSecurityConfig="@xml/network_security_config"
   

2. create in folder xml this file network_security_config.xml and write this:

   <?xml version="1.0" encoding="utf-8"?>
     <network-security-config>
       <base-config cleartextTrafficPermitted="true" />
     </network-security-config>
   

3. inside tag application add this tag:

   <uses-library android:name="org.apache.http.legacy" android:required="false"/>
   

I'm no expert but I'd say that if you really want to be semantic, you should use vocabularies (RDFa).

This should result in something like that:

<em property="italic" href="http://url/to/a/definition_of_italic"> Your text </em>

em is used for the presentation (humans will see it in italic) and the property and href attributes are linking to a definition of what italic is (for machines).

You should check if there's a vocabulary for that kind of thing, maybe properties already exist.

More info about RDFa here: http://www.alistapart.com/articles/introduction-to-rdfa/

While the other answers got it right when it comes to add comments, in my case only the following worked.

• Multi-line uncomment

  select the lines to be uncommented + Ctrl + 1

Actually

{
  @synchronized(self) {
    return [[myString retain] autorelease];
  }
}

transforms directly into:

// needs #import <objc/objc-sync.h>
{
  objc_sync_enter(self)
    id retVal = [[myString retain] autorelease];
  objc_sync_exit(self);
  return retVal;
}

This API available since iOS 2.0 and imported using...

#import <objc/objc-sync.h>

I found that you can detect the command key in the latest version of Safari (7.0: 9537.71) if it is pressed in conjunction with another key. For example, if you want to detect ?+x:, you can detect the x key AND check if event.metaKey is set to true. For example:

var key = event.keyCode || event.charCode || 0;
console.log(key, event.metaKey);

When pressing x on it's own, this will output 120, false. When pressing ?+x, it will output 120, true

This only seems to work in Safari - not Chrome

Yes, there is a way. Its called custom fonts in CSS.Your CSS needs to be modified, and you need to upload those fonts to your website.

The CSS required for this is:

@font-face {
     font-family: Thonburi-Bold;
     src: url('pathway/Thonburi-Bold.otf'); 
}

- (NSString *)removeWhitespaces {
  return [[self componentsSeparatedByCharactersInSet:
                    [NSCharacterSet whitespaceCharacterSet]]
      componentsJoinedByString:@""];
}

You almost always use HashMap, you should only use TreeMap if you need your keys to be in a specific order.

dict.fromkeys(keys, None)

I would just use a Union

In your second query add the extra column name and add a '' in all the corresponding locations in the other queries

Example

//reverse order to get the column names
select top 10 personId, '' from Telephone//No Column name assigned 
Union 
select top 10 personId, loanId from loan

With python 3 you can reverse the string in-place meaning it won't get assigned to another variable. First you have to convert the string into a list and then leverage the reverse() function.

https://docs.python.org/3/tutorial/datastructures.html

   def main():
        my_string = ["h","e","l","l","o"]
        print(reverseString(my_string))

    def reverseString(s):
      print(s)
      s.reverse()
      return s

    if __name__ == "__main__":
        main()

To convert the current epoch time in [ms] to a 24-hour time. You might need to specify the option to disable 12-hour format.

$ node.exe -e "var date = new Date(Date.now()); console.log(date.toLocaleString('en-GB', { hour12:false } ));"

2/7/2018, 19:35:24

or as JS:

var date = new Date(Date.now()); 
console.log(date.toLocaleString('en-GB', { hour12:false } ));
// 2/7/2018, 19:35:24

console.log(date.toLocaleString('en-GB', { hour:'numeric', minute:'numeric', second:'numeric', hour12:false } ));
// 19:35:24

Note: The use of en-GB here, is just a (random) choice of a place using the 24 hour format, it is not your timezone!

You can also take a look at PDFMiner (or for older versions of Python see PDFMiner and PDFMiner).

A particular feature of interest in PDFMiner is that you can control how it regroups text parts when extracting them. You do this by specifying the space between lines, words, characters, etc. So, maybe by tweaking this you can achieve what you want (that depends of the variability of your documents). PDFMiner can also give you the location of the text in the page, it can extract data by Object ID and other stuff. So dig in PDFMiner and be creative!

But your problem is really not an easy one to solve because, in a PDF, the text is not continuous, but made from a lot of small groups of characters positioned absolutely in the page. The focus of PDF is to keep the layout intact. It's not content oriented but presentation oriented.

It would have worked out of the box if you hadn't used @EnableWebMvc annotation. When you do that you switch off all the things that Spring Boot does for you in WebMvcAutoConfiguration. You could remove that annotation, or you could add back the view controller that you switched off:

@Override
public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/").setViewName("forward:/index.html");
}

To Start Tomcat7 Service :

• Open cmd, go to bin directory within "Apache Tomcat 7" folder. You will see some this like C:\..\bin>

• Enter above command to start the service: C:\..\bin>service.bat install. The service will get started now.

• Enter above command to start tomcat7w monitory service. If you have issue with starting the tomcat7 service then remove the service with command : C:\..\bin>tomcat7 //DS//Tomcat7

• Now the service will no longer exist. Try the install command again, now the service will get installed and started: C:\..\bin>tomcat7w \\MS\tomcat7w

• You will see the tomcat 7 icon in the system tray. Now, the tomcat7 service and tomcat7w will start automatically when the windows get start.

try this

    $('#div_id').animate({scrollTop:0}, '500', 'swing');

Look at it this way - is it more efficient to throw out the kitchen garbage when the garbage can is at 10% or let it fill up before taking it out?

By not letting it fill up, you are wasting your time walking to and from the garbage bin outside. This analogous to what happens when the GC thread runs - all the managed threads are suspended while it is running. And If I am not mistaken, the GC thread can be shared among multiple AppDomains, so garbage collection affects all of them.

Of course, you might encounter a situation where you won't be adding anything to the garbage can anytime soon - say, if you're going to take a vacation. Then, it would be a good idea to throw out the trash before going out.

This MIGHT be one time that forcing a GC can help - if your program idles, the memory in use is not garbage-collected because there are no allocations.

UPDATE MyTable SET MyDate = CONVERT(datetime, '2009/07/16 08:28:01', 120)

For a full discussion of CAST and CONVERT, including the different date formatting options, see the MSDN Library Link below:

https://docs.microsoft.com/en-us/sql/t-sql/functions/cast-and-convert-transact-sql

I think you can't achieve what you want in a more efficient manner than you proposed.

The underlying problem is that the timestamps (as you seem aware) are made up of two parts. The data that represents the UTC time, and the timezone, tz_info. The timezone information is used only for display purposes when printing the timezone to the screen. At display time, the data is offset appropriately and +01:00 (or similar) is added to the string. Stripping off the tz_info value (using tz_convert(tz=None)) doesn't doesn't actually change the data that represents the naive part of the timestamp.

So, the only way to do what you want is to modify the underlying data (pandas doesn't allow this... DatetimeIndex are immutable -- see the help on DatetimeIndex), or to create a new set of timestamp objects and wrap them in a new DatetimeIndex. Your solution does the latter:

pd.DatetimeIndex([i.replace(tzinfo=None) for i in t])

For reference, here is the replace method of Timestamp (see tslib.pyx):

def replace(self, **kwds):
    return Timestamp(datetime.replace(self, **kwds),
                     offset=self.offset)

You can refer to the docs on datetime.datetime to see that datetime.datetime.replace also creates a new object.

If you can, your best bet for efficiency is to modify the source of the data so that it (incorrectly) reports the timestamps without their timezone. You mentioned:

I want to work with timezone naive timeseries (to avoid the extra hassle with timezones, and I do not need them for the case I am working on)

I'd be curious what extra hassle you are referring to. I recommend as a general rule for all software development, keep your timestamp 'naive values' in UTC. There is little worse than looking at two different int64 values wondering which timezone they belong to. If you always, always, always use UTC for the internal storage, then you will avoid countless headaches. My mantra is Timezones are for human I/O only.

If you use a cordova to build your app, for me the best soluction is change the argument cdvMinSdkVersion=15 to cdvMinSdkVersion=19 in the file platforms\android\gradle.properties

http://martinfowler.com/articles/microservice-testing/

Martin Fowler's blog post speaks about strategies to test code (Especially in a micro-services architecture) but most of it applies to any application.

I'll quote from his summary slide:

• Unit tests - exercise the smallest pieces of testable software in the application to determine whether they behave as expected.
• Integration tests - verify the communication paths and interactions between components to detect interface defects.
• Component tests - limit the scope of the exercised software to a portion of the system under test, manipulating the system through internal code interfaces and using test doubles to isolate the code under test from other components.
• Contract tests - verify interactions at the boundary of an external service asserting that it meets the contract expected by a consuming service.
• End-To-End tests - verify that a system meets external requirements and achieves its goals, testing the entire system, from end to end.

I had the same problem, I had the package and class named the same. I renamed the class, then clean and build. Then I set the main class in the "run" under the properties of the project. I works now.

One easy trick that can help with most deadlocks is sorting the operations in a specific order.

You get a deadlock when two transactions are trying to lock two locks at opposite orders, ie:

• connection 1: locks key(1), locks key(2);
• connection 2: locks key(2), locks key(1);

If both run at the same time, connection 1 will lock key(1), connection 2 will lock key(2) and each connection will wait for the other to release the key -> deadlock.

Now, if you changed your queries such that the connections would lock the keys at the same order, ie:

• connection 1: locks key(1), locks key(2);
• connection 2: locks key(1), locks key(2);

it will be impossible to get a deadlock.

So this is what I suggest:

1. Make sure you have no other queries that lock access more than one key at a time except for the delete statement. if you do (and I suspect you do), order their WHERE in (k1,k2,..kn) in ascending order.

2. Fix your delete statement to work in ascending order:

Change

DELETE FROM onlineusers 
WHERE datetime <= now() - INTERVAL 900 SECOND

To

DELETE FROM onlineusers 
WHERE id IN (
    SELECT id FROM onlineusers
    WHERE datetime <= now() - INTERVAL 900 SECOND 
    ORDER BY id
) u;

Another thing to keep in mind is that mysql documentation suggest that in case of a deadlock the client should retry automatically. you can add this logic to your client code. (Say, 3 retries on this particular error before giving up).

Simply like that:

arr.join("")

I want to add this note to what said above.

Suppose you are using Spring Rest with this simple architect:

Controller <-> Service <-> Repository

And you want to return some data to the front-end, if you are using FetchType.LAZY, you will get an exception after you return data to the controller method since the session is closed in the Service so the JSON Mapper Object can't get the data.

There is three common options to solve this problem, depends on the design, performance and the developer:

1. The easiest one is to use FetchType.EAGER, So that the session will still alive at the controller method, but this method will impact the performance.
2. Anti-patterns solutions, to make the session live until the execution ends, it is make a huge performance issue in the system.
3. The best practice is to use FetchType.LAZY with mapper like MapStruct to transfer data from Entity to another data object DTO and then send it back to the controller, so there is no exception if the session closed.

Have you tried the arrange > auto arrange function in MySQL Workbench. It may save you from manually moving the tables around.

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

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

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).)

This is a solution that avoids the troublesome Date object and timezone issues, it requires that your input date be in the format "yyyy-dd-mm". If you want to change the format, then modify date_str_to_parts function:

    function get_day_of_year(str_date){
    var date_parts = date_str_to_parts(str_date);
    var is_leap = (date_parts.year%4)==0;
    var acct_for_leap = (is_leap && date_parts.month>2);
    var day_of_year = 0;

    var ary_months = [
        0,
        31, //jan
        28, //feb(non leap)
        31, //march
        30, //april
        31, //may
        30, //june
        31, //july
        31, //aug
        30, //sep
        31, //oct
        30, //nov   
        31  //dec
        ];


    for(var i=1; i < date_parts.month; i++){
        day_of_year += ary_months[i];
    }

    day_of_year += date_parts.date;

    if( acct_for_leap ) day_of_year+=1;

    return day_of_year;

}

function date_str_to_parts(str_date){
    return {
        "year":parseInt(str_date.substr(0,4),10),
        "month":parseInt(str_date.substr(5,2),10),
        "date":parseInt(str_date.substr(8,2),10)
    }
}

First of all, let's try to make your code a little simpler:

// No need to create a circle unless it is clearly necessary to
// demonstrate the problem

// Your Rect2f defines a default constructor, so let's use it for simplicity.
shared_ptr<Shape> rect(new Rect2f());

Okay, so now we see that the parentheses are clearly balanced. What else could it be? Let's check the following code snippet's error:

int main() {
    delete new T();
}

This may seem like weird usage, and it is, but I really hate memory leaks. However, the output does seem useful:

In function 'int main()':
Line 2: error: expected type-specifier before 'T'

Aha! Now we're just left with the error about the parentheses. I can't find what causes that; however, I think you are forgetting to include the file that defines Rect2f.

As a supplement of the answer of Michael Parker, you can make getData accept a callback function to active the setState update the data:

componentWillMount : function () {
    var data = this.getData(()=>this.setState({data : data}));
},

Just a mention with jQuery v3.2.1 and Laravel 5.6.

Case 1: The JS object posted directly, like:

$.post("url", {name:'John'}, function( data ) {
});

Corresponding Laravel PHP code should be:

parse_str($request->getContent(),$data); //JSON will be parsed to object $data

Case 2: The JSON string posted, like:

$.post("url", JSON.stringify({name:'John'}), function( data ) {
});

Corresponding Laravel PHP code should be:

$data = json_decode($request->getContent(), true);

Have a look at the following apache commons function:

org.apache.commons.io.FileUtils.readFileToByteArray(File)

Before proceeding further with the fuss of immutability, let's just take a look into the String class and its functionality a little before coming to any conclusion.

This is how String works:

String str = "knowledge";

This, as usual, creates a string containing "knowledge" and assigns it a reference str. Simple enough? Lets perform some more functions:

 String s = str;     // assigns a new reference to the same string "knowledge"

Lets see how the below statement works:

  str = str.concat(" base");

This appends a string " base" to str. But wait, how is this possible, since String objects are immutable? Well to your surprise, it is.

When the above statement is executed, the VM takes the value of String str, i.e. "knowledge" and appends " base", giving us the value "knowledge base". Now, since Strings are immutable, the VM can't assign this value to str, so it creates a new String object, gives it a value "knowledge base", and gives it a reference str.

An important point to note here is that, while the String object is immutable, its reference variable is not. So that's why, in the above example, the reference was made to refer to a newly formed String object.

At this point in the example above, we have two String objects: the first one we created with value "knowledge", pointed to by s, and the second one "knowledge base", pointed to by str. But, technically, we have three String objects, the third one being the literal "base" in the concat statement.

Important Facts about String and Memory usage

What if we didn't have another reference s to "knowledge"? We would have lost that String. However, it still would have existed, but would be considered lost due to having no references. Look at one more example below

String s1 = "java";
s1.concat(" rules");
System.out.println("s1 refers to "+s1);  // Yes, s1 still refers to "java"

What's happening:

1. The first line is pretty straightforward: create a new String "java" and refer s1 to it.
2. Next, the VM creates another new String "java rules", but nothing refers to it. So, the second String is instantly lost. We can't reach it.

The reference variable s1 still refers to the original String "java".

Almost every method, applied to a String object in order to modify it, creates new String object. So, where do these String objects go? Well, these exist in memory, and one of the key goals of any programming language is to make efficient use of memory.

As applications grow, it's very common for String literals to occupy large area of memory, which can even cause redundancy. So, in order to make Java more efficient, the JVM sets aside a special area of memory called the "String constant pool".

When the compiler sees a String literal, it looks for the String in the pool. If a match is found, the reference to the new literal is directed to the existing String and no new String object is created. The existing String simply has one more reference. Here comes the point of making String objects immutable:

In the String constant pool, a String object is likely to have one or many references. If several references point to same String without even knowing it, it would be bad if one of the references modified that String value. That's why String objects are immutable.

Well, now you could say, what if someone overrides the functionality of String class? That's the reason that the String class is marked final so that nobody can override the behavior of its methods.

Also please remember resolutions [quantum of time] are different.

fi

While others have pointed out it is not possible to override constructors syntactically, I would like to also point out, it would be conceptually bad to do so. Say the superclass is a dog object, and the subclass is a Husky object. The dog object has properties such as "4 legs", "sharp nose", if "override" means erasing dog and replacing it with Husky then Husky would be missing these properties and be a broken object. Husky never had those properties and simply inherited them from dog. On the other hand, if you intend to give Husky everything that dog has, then conceptually you could "override" dog with Husky, but there would be no point in creating a class that is the same as dog, it's not practically an inherited class but a complete replacement.

You can also look at the following if you use WPF or reference System.Windows.Input

if (Keyboard.Modifiers == ModifierKeys.Shift)

The Keyboard namespace can also be used to check the pressed state of other keys with Keyboard.IsKeyDown(Key), or if you are subscribing to a KeyDownEvent or similar event, the event arguments carry a list of currently pressed keys.

Yes you have to if you take the unique_ptr by value in the constructor. Explicity is a nice thing. Since unique_ptr is uncopyable (private copy ctor), what you wrote should give you a compiler error.

If the following conditions are true, then rewrite the URL:
If the requested filename is not a directory,

RewriteCond %{REQUEST_FILENAME} !-d

and if the requested filename is not a regular file that exists,

RewriteCond %{REQUEST_FILENAME} !-f

and if the requested filename is not a symbolic link,

RewriteCond %{REQUEST_FILENAME} !-l

then rewrite the URL in the following way:
Take the whole request filename and provide it as the value of a "url" query parameter to index.php. Append any query string from the original URL as further query parameters (QSA), and stop processing this .htaccess file (L).

RewriteRule ^(.+)$ index.php?url=$1 [QSA,L]

Another Example:

RewriteRule "/pages/(.+)" "/page.php?page=$1" [QSA]

With the [QSA] flag, a request for

/pages/123?one=two

will be mapped to

/page.php?page=123&one=two

As a general rule, modifying schema based on something that a user could change (such as adding a question to a survey) should be considered fairly smelly. There's cases where it can be appropriate, particularly when dealing with large amounts of data, but know what you're getting into before you dive in. Having just a "responses" table for each survey means that adding or removing questions is potentially very costly, and it's very difficult to do analytics in a question-agnostic way.

I think your second approach is best, but if you're certain you're going to have a lot of scale concerns, one thing that has worked for me in the past is a hybrid approach:

1. Create detailed response tables to store per-question responses as you've described in 2. This data would generally not be directly queried from your application, but would be used for generating summary data for reporting tables. You'd probably also want to implement some form of archiving or expunging for this data.
2. Also create the responses table from 1 if necessary. This can be used whenever users want to see a simple table for results.
3. For any analytics that need to be done for reporting purposes, schedule jobs to create additional summary data based on the data from 1.

This is absolutely a lot more work to implement, so I really wouldn't advise this unless you know for certain that this table is going to run into massive scale concerns.

You can do it in one line without nltk (python 3.x).

import string
string_text= string_text.translate(str.maketrans('','',string.punctuation))

See String.format method.

String s = "hello %s!";
s = String.format(s, "world");
assertEquals(s, "hello world!"); // should be true

This works for me. use MAX(CONVERT(date, ReportDate)) to make sure you have date value

select max( CONVERT(date, ReportDate)) FROM [TraxHistory]

while 1:
    root.update()

... is (very!) roughly similar to:

root.mainloop()

The difference is, mainloop is the correct way to code and the infinite loop is subtly incorrect. I suspect, though, that the vast majority of the time, either will work. It's just that mainloop is a much cleaner solution. After all, calling mainloop is essentially this under the covers:

while the_window_has_not_been_destroyed():
    wait_until_the_event_queue_is_not_empty()
    event = event_queue.pop()
    event.handle()

... which, as you can see, isn't much different than your own while loop. So, why create your own infinite loop when tkinter already has one you can use?

Put in the simplest terms possible: always call mainloop as the last logical line of code in your program. That's how Tkinter was designed to be used.

In C++ a class with at least one pure virtual function is called abstract class. You can not create objects of that class, but may only have pointers or references to it.

If you are deriving from an abstract class, then make sure you override and define all pure virtual functions for your class.

From your snippet Your class AliceUniversity seems to be an abstract class. It needs to override and define all the pure virtual functions of the classes Graduate and UniversityGraduate.

Pure virtual functions are the ones with = 0; at the end of declaration.

Example: virtual void doSomething() = 0;

For a specific answer, you will need to post the definition of the class for which you get the error and the classes from which that class is deriving.

Here's a list of keycodes that includes a way to look them up interactively.

The fix is to increase the MySQL daemon’s max_allowed_packet. You can do this to a running daemon by logging in as Super and running the following commands.

# mysql -u admin -p

mysql> set global net_buffer_length=1000000;
Query OK, 0 rows affected (0.00 sec)

mysql> set global max_allowed_packet=1000000000;
Query OK, 0 rows affected (0.00 sec)

Then to import your dump:

gunzip < dump.sql.gz | mysql -u admin -p database

A for...in loop always enumerates the keys. Objects properties keys are always String, even the indexed properties of an array :

var myArray = ['a', 'b', 'c', 'd'];
var total = 0
for (elem in myArray) {
  total += elem
}
console.log(total); // 00123

If you don't want to use the url helper, you can get the same results by using the following variable:

$this->config->config['base_url']

It will return the base url for you with no extra steps required.

Since you declare sample inside the anonymous function you pass to ready, it is scoped to that function.

You then pass a string to setTimeout which is evaled after 2 seconds. This takes place outside the current scope, so it can't find the function.

Only pass functions to setTimeout, using eval is inefficient and hard to debug.

setTimeout(sample,2000)

Create a mysqldump file in the system which has the datas and use pipe to give this mysqldump file as an input to the new system. The new system can be connected using ssh command.

mysqldump -u user -p'password' db-name | ssh user@some_far_place.com mysql -u user -p'password' db-name

no space between -p[password]

Don't know if this is an option, but it would work very similar to Zend's pdf library, but you don't need to load a bunch of extra code (the zend framework). It just extends FPDF.

http://www.setasign.de/products/pdf-php-solutions/fpdi/

Here you can basically do the same thing. Load the PDF, write over top of it, and then save to a new PDF. In FPDI you basically insert the PDF as an image so you can put whatever you want over it.

But again, this uses FPDF, so if you don't want to use that, then it won't work.

Can I suggest that you reload it into a non-DOM image object? If it's cached, this will take no time at all, and the onload will still fire. If it isn't cached, it will fire the onload when the image is loaded, which should be the same time as the DOM version of the image finishes loading.

Javascript:

$(document).ready(function() {
    var tmpImg = new Image() ;
    tmpImg.src = $('#img').attr('src') ;
    tmpImg.onload = function() {
        // Run onload code.
    } ;
}) ;

Updated (to handle multiple images and with correctly ordered onload attachment):

$(document).ready(function() {
    var imageLoaded = function() {
        // Run onload code.
    }
    $('#img').each(function() {
        var tmpImg = new Image() ;
        tmpImg.onload = imageLoaded ;
        tmpImg.src = $(this).attr('src') ;
    }) ;
}) ;

Here is a code snippet, that counts number of files in a particular HDFS directory (I used this to determine how many reducers to use in a particular ETL code). You can easily modify this to suite your needs.

private int calculateNumberOfReducers(String input) throws IOException {
    int numberOfReducers = 0;
    Path inputPath = new Path(input);
    FileSystem fs = inputPath.getFileSystem(getConf());
    FileStatus[] statuses = fs.globStatus(inputPath);
    for(FileStatus status: statuses) {
        if(status.isDirectory()) {
            numberOfReducers += getNumberOfInputFiles(status, fs);
        } else if(status.isFile()) {
            numberOfReducers ++;
        }
    }
    return numberOfReducers;
}

/**
 * Recursively determines number of input files in an HDFS directory
 *
 * @param status instance of FileStatus
 * @param fs instance of FileSystem
 * @return number of input files within particular HDFS directory
 * @throws IOException
 */
private int getNumberOfInputFiles(FileStatus status, FileSystem fs) throws IOException  {
    int inputFileCount = 0;
    if(status.isDirectory()) {
        FileStatus[] files = fs.listStatus(status.getPath());
        for(FileStatus file: files) {
            inputFileCount += getNumberOfInputFiles(file, fs);
        }
    } else {
        inputFileCount ++;
    }

    return inputFileCount;
}

If your repository enables setting revision properties via the pre-revprop-change hook you can change log messages much easier.

svn propedit --revprop -r 1234 svn:log url://to/repository

Or in TortoiseSVN, AnkhSVN and probably many other subversion clients by right clicking on a log entry and then 'change log message'.

What about using .splitlines()?

for line in textData.splitlines():
    print(line)
    lineResult = libLAPFF.parseLine(line)

In modern browser you can use canvas to load/save image data. But you should keep in mind several things if you resize image on the client:

1. You will have only 8bits per channel (jpeg can have better dynamic range, about 12 bits). If you don't upload professional photos, that should not be a problem.
2. Be careful about resize algorithm. The most of client side resizers use trivial math, and result is worse than it could be.
3. You may need to sharpen downscaled image.
4. If you wish do reuse metadata (exif and other) from original - don't forget to strip color profile info. Because it's applied when you load image to canvas.

$("#myid li").click(function() {
    alert(this.id); // id of clicked li by directly accessing DOMElement property
    alert($(this).attr('id')); // jQuery's .attr() method, same but more verbose
    alert($(this).html()); // gets innerHTML of clicked li
    alert($(this).text()); // gets text contents of clicked li
});

If you are talking about replacing the ID with something:

$("#myid li").click(function() {
    this.id = 'newId';

    // longer method using .attr()
    $(this).attr('id', 'newId');
});

Demo here. And to be fair, you should have first tried reading the documentation:

• http://api.jquery.com/category/selectors/
• http://api.jquery.com/category/events/
• http://api.jquery.com/attr/

In the left list, right click on "AppIcon" and click on "Open in finder" A folder with name "AppIcon.appiconset" will open. Paste all the graphics with required resolution there. Once done, all those images will be visible in this same screen(one in your screen shot). then drag them to appropriate box. App icons have been added. Same process for Launch images. Launch images through this process are added for iOS 7 and below. For iOS 8 separate LaunchScreen.xib file is made by default.

Put a global variable to generate the ids.

<script>
    $(function(){
        // Variable to get ids for the checkboxes
        var idCounter=1;
        $("#btn1").click(function(){
            var val = $("#txtAdd").val();
            $("#divContainer").append ( "<label for='chk_" + idCounter + "'>" + val + "</label><input id='chk_" + idCounter + "' type='checkbox' value='" + val + "' />" );
            idCounter ++;
        });
    });
</script>
<div id='divContainer'></div>
<input type="text" id="txtAdd" /> 
<button id="btn1">Click</button>

TLDR; technically space sorts before exclamation mar, and can be used by preceding it with ' or - (which will be ignored in sorting), but exclamation mark follows right after space, and is easier to use.

On windows 7 at least, a minus sign (-) and (') seem to be ignored in a name except for one quirk: in a name that is otherwise identical, the ' will be sorted before -, for example: (a'a) will sort above (a-a)

Empty string will sort above everything else, which means for example aa will sort above aaa because the 'empty string' after two a letters will sort before the third 'a'.

This also means that aa will be sorted above a'a because the 'empty string' between two a letters will sort above the ' mark.

What follows then is, ' alone will sort first, because technically it's an empty string. However adding for example letters behind it will sort the name as if the ' didn't exist.

Since the first 'unignored' character (as far as I know) is space, in case you want to sort 'real names' above others, the best way to go would be ' followed by space, and then the name you want to actually use. For example: (' first)

You can of course top that by using more than one space in the strong, such as (' firster) and (' firstest) with two and three blanks before the f.

While minus sign sorts below ' in otherwise similar name, there's no other difference in sorting (that I know of), and I find minus sign visually clearer, so if I want to put something on top of list, I'd use minus followed by space, then the 'actual name', for example: (- first file -)

If you are worried about using space on the filename, then exclamation mark (!) is the next best thing - and since it can appear as first character on a string, it's easier to use.

for i in range(100):
try:
  #Your code here

This one worked for me.

According to the latest document when state is set to be directory, you don't need to use parameter recurse to create parent directories, file module will take care of it.

- name: create directory with parent directories
  file:
    path: /data/test/foo
    state: directory

this is fare enough to create the parent directories data and test with foo

please refer the parameter description - "state" http://docs.ansible.com/ansible/latest/modules/file_module.html

You can also do something:

SELECT CAST(CAST(34512367.392 AS decimal(30,9)) AS NVARCHAR(100))

Output: 34512367.392000000

New Item>Project Name = abc > Instead of Freestyle job, select Copy from job name of already existing jobs

If you are inside the folder that you want to copy out of the directory then use ../.

Do keep in mind that the file.getContentType could also output application/octet-stream instead of the required application/vnd.openxmlformats-officedocument.spreadsheetml.sheet when you try to upload the file that is already open.

For the case that you wish to revert a recently installed package that made several changes to dependencies (such as tensorflow), you can "roll back" to an earlier installation state via the following method:

conda list --revisions
conda install --revision [revision number]

The first command shows previous installation revisions (with dependencies) and the second reverts to whichever revision number you specify.

Note that if you wish to (re)install a later revision, you may have to sequentially reinstall all intermediate versions. If you had been at revision 23, reinstalled revision 20 and wish to return, you may have to run each:

conda install --revision 21
conda install --revision 22
conda install --revision 23

Basically:

Use IncludeErrorDetailPolicy instead if CustomErrors doesn't solve it for you (e.g. if you're ASP.NET stack is >2012):

GlobalConfiguration.Configuration.IncludeErrorDetailPolicy 
= IncludeErrorDetailPolicy.Always;

Note: Be careful returning detailed error info can reveal sensitive information to 'hackers'. See Simon's comment on this answer below.

TL;DR version

For me CustomErrors didn't really help. It was already set to Off, but I still only got a measly an error has occurred message. I guess the accepted answer is from 3 years ago which is a long time in the web word nowadays. I'm using Web API 2 and ASP.NET 5 (MVC 5) and Microsoft has moved away from an IIS-only strategy, while CustomErrors is old skool IIS ;).

Anyway, I had an issue on production that I didn't have locally. And then found I couldn't see the errors in Chrome's Network tab like I could on my dev machine. In the end I managed to solve it by installing Chrome on my production server and then browsing to the app there on the server itself (e.g. on 'localhost'). Then more detailed errors appeared with stack traces and all.

Only afterwards I found this article from Jimmy Bogard (Note: Jimmy is mr. AutoMapper!). The funny thing is that his article is also from 2012, but in it he already explains that CustomErrors doesn't help for this anymore, but that you CAN change the 'Error detail' by setting a different IncludeErrorDetailPolicy in the global WebApi configuration (e.g. WebApiConfig.cs):

GlobalConfiguration.Configuration.IncludeErrorDetailPolicy 
= IncludeErrorDetailPolicy.Always;

Luckily he also explains how to set it up that webapi (2) DOES listen to your CustomErrors settings. That's a pretty sensible approach, and this allows you to go back to 2012 :P.

Note: The default value is 'LocalOnly', which explains why I was able to solve the problem the way I described, before finding this post. But I understand that not everybody can just remote to production and startup a browser (I know I mostly couldn't until I decided to go freelance AND DevOps).

If you are using Java 6, you can use the following oneliner to read an integer from console:

int n = Integer.parseInt(System.console().readLine());

I removed the following entry from web.config and it worked for me.

<dependentAssembly>
                <assemblyIdentity name="System.Web.Http.WebHost" culture="neutral" publicKeyToken="31BF3856AD364E35" />
                <bindingRedirect oldVersion="0.0.0.0-65535.65535.65535.65535" newVersion="5.2.6.0" />
            </dependentAssembly>

I landed here when I was trying to do a similar thing. For a application/x-www-form-urlencoded content type, you could try to use this for the body:

var body = 'username' =myusername & 'password'=mypassword;

with what you tried doing the value assigned to body will be a string.

In addition to @Boaz's and @vegemite4me's answers....

By implementing ImplicitNamingStrategy you may create rules for automatically naming the constraints. Note you add your naming strategy to the metadataBuilder during Hibernate's initialization:

metadataBuilder.applyImplicitNamingStrategy(new MyImplicitNamingStrategy());

It works for @UniqueConstraint, but not for @Column(unique = true), which always generates a random name (e.g. UK_3u5h7y36qqa13y3mauc5xxayq).

There is a bug report to solve this issue, so if you can, please vote there to have this implemented. Here: https://hibernate.atlassian.net/browse/HHH-11586

Thanks.

Using display:none is not SEO-friendly. The following way allows the hidden content to be searchable. Adding the transition-delay ensures any links included in the hidden content is clickable.

}

.collapse > div {

I know I'm late :) But this how i do it:

public static void AddOrUpdateAppSettings(string key, string value)
{
    try
    {
        var configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        var settings = configFile.AppSettings.Settings;
        if (settings[key] == null)
        {
            settings.Add(key, value);
        }
        else
        {
            settings[key].Value = value;
        }
        configFile.Save(ConfigurationSaveMode.Modified);
        ConfigurationManager.RefreshSection(configFile.AppSettings.SectionInformation.Name);
    }
    catch (ConfigurationErrorsException)
    {
        Console.WriteLine("Error writing app settings");
    }
}

Try restarting your IDE. It worked for me. Although I tried to end the process in the task manager, the process never got killed.

Well, you can stick one or more "soft hyphens" (­) in your long unbroken strings. I doubt that old IE versions deal with that correctly, but what it's supposed to do is tell the browser about allowable word breaks that it can use if it has to.

Now, how exactly would you pick where to stuff those characters? That depends on the actual string and what it means, I guess.

I think what you want is to set the android:layout_weight,

http://developer.android.com/resources/tutorials/views/hello-linearlayout.html

something like this (I'm just putting text views above and below as placeholders):

  <LinearLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:weightSum="1">
    <TextView
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="68"/>
    <Gallery 
        android:id="@+id/gallery"
        android:layout_width="fill_parent"
        android:layout_height="0dp"

        android:layout_weight="16"
    />
    <TextView
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="16"/>

  </LinearLayout>

1. Close Android Studio (if Android Studio is running)
2. Run Genymotion as administrator

that's all! simple.

You could also use the stringr package:

library(stringr)
str_length("foo")
[1] 3

Ultimate way to do this.

ngOnInit() {
  this.interPretationForm.controls.InterpretationType.valueChanges.takeWhile(()=> this.alive).subscribe(val =>{
    console.log(val); // You check code. it will be executed every time value change.
  })
}

LinkedHashMap is precisely what you're looking for.

It is exactly like HashMap, except that when you iterate over it, it presents the items in the insertion order.

MySQL allows a more readable way to combine multiple updates into a single query. This seems to better fit the scenario you describe, is much easier to read, and avoids those difficult-to-untangle multiple conditions.

INSERT INTO table_users (cod_user, date, user_rol, cod_office)
VALUES
('622057', '12082014', 'student', '17389551'),
('2913659', '12082014', 'assistant','17389551'),
('6160230', '12082014', 'admin', '17389551')
ON DUPLICATE KEY UPDATE
 cod_user=VALUES(cod_user), date=VALUES(date)

This assumes that the user_rol, cod_office combination is a primary key. If only one of these is the primary key, then add the other field to the UPDATE list. If neither of them is a primary key (that seems unlikely) then this approach will always create new records - probably not what is wanted.

However, this approach makes prepared statements easier to build and more concise.

The Github application for Windows shows all remote branches of a repository. If you have deleted the branch locally with $ git branch -d [branch_name], the remote branch still exists in your Github repository and will appear regardless in the Windows Github application.

If you want to delete the branch completely (remotely as well), use the above command in combination with $ git push origin :[name_of_your_new_branch]. Warning: this command erases all existing branches and may cause loss of code. Be careful, I do not think this is what you are trying to do.

However every time you delete the local branch changes, the remote branch will still appear in the application. If you do not want to keep making changes, just ignore it and do not click, otherwise you may clone the repository. If you had any more questions, please let me know.

RE: Apparently when command.com is invoked is a bit of a complex mystery;

Several months ago, during the course of a project, we had to figure out why some programs that we wanted to run under CMD.EXE were, in fact, running under COMMAND.COM. The "program" in question was a very old .BAT file, that still runs daily.

We discovered that the reason the batch file ran under COMMAND.COM is that it was being started from a .PIF file (also ancient). Since the special memory configuration settings available only through a PIF have become irrelevant, we replaced it with a conventional desktop shortcut.

The same batch file, launched from the shortcut, runs in CMD.EXE. When you think about it, this makes sense. The reason that it took us so long to figure it out was partially due to the fact that we had forgotten that its item in the startup group was a PIF, because it had been in production since 1998.

long milliseconds = DateTime.Now.Ticks / TimeSpan.TicksPerMillisecond;

This is actually how the various Unix conversion methods are implemented in the DateTimeOffset class (.NET Framework 4.6+, .NET Standard 1.3+):

long milliseconds = DateTimeOffset.Now.ToUnixTimeMilliseconds();

SELECT DATEDIFF(day,'2014-06-05','2014-08-05') AS DiffDate

diffdate is column name.

result:

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

I have encountered the same issue. The reason was that the library that I was trying to use had been compiled with a standard JDK 7.

I recompiled it with the -source 1.6 -target 1.6 options and it worked fine.

Looks like you want git diff and/or git log. Also check out gitk

gitk path/to/file
git diff path/to/file
git log path/to/file

Try this:

this.statusCode = 302;
this.setHeader('Location', '/url/to/redirect');
this.end();

Full example:

private static final Pattern p = Pattern.compile("^([a-zA-Z]+)([0-9]+)(.*)");
public static void main(String[] args) {
    // create matcher for pattern p and given string
    Matcher m = p.matcher("Testing123Testing");

    // if an occurrence if a pattern was found in a given string...
    if (m.find()) {
        // ...then you can use group() methods.
        System.out.println(m.group(0)); // whole matched expression
        System.out.println(m.group(1)); // first expression from round brackets (Testing)
        System.out.println(m.group(2)); // second one (123)
        System.out.println(m.group(3)); // third one (Testing)
    }
}

Since you're looking for the first number, you can use such regexp:

^\D+(\d+).*

and m.group(1) will return you the first number. Note that signed numbers can contain a minus sign:

^\D+(-?\d+).*

do this in two steps:

1. replace not letter characters with this regex:

   [\/\&%#\$]

2. replace quotes with this regex:

   [\"\']

and use preg_replace:

$stringWithoutNonLetterCharacters = preg_replace("/[\/\&%#\$]/", "_", $yourString);
$stringWithQuotesReplacedWithSpaces = preg_replace("/[\"\']/", " ", $stringWithoutNonLetterCharacters);

You can use the adb command which comes in the tools dir of the SDK:

adb shell

It will give you a command line prompt where you can browse and access the filesystem. Or you can extract the files you want:

adb pull /sdcard/the_file_you_want.txt

Also, if you use eclipse with the ADT, there's a view to browse the file system (Window->Show View->Other... and choose Android->File Explorer)

You can try this command,

adb shell dumpsys activity recents

There you can find current activity name in activity stack.

To get most recent activity name:

adb shell dumpsys activity recents | find "Recent #0"

dG will delete from the current line to the end of file

dCtrl+End will delete from the cursor to the end of the file

But if this file is as large as you say, you may be better off reading the first few lines with head rather than editing and saving the file.

head hugefile > firstlines

(If you are on Windows you can use the Win32 port of head)

In my case there was a conflict in the namespaces , I have:

using System.Web.Mvc;

and

using System.Collections.Generic;

I explicitly want to use the Mvc one so I declared it as :

new System.Web.Mvc.SelectList(...)

To print those numbers in C do the following:

printf("%d", addNumbers(a,b));

If expression returns a boolean, you can just return the result of it.

Example

 return (a > b)

DateTime dt = new DateTime();// gives 01/01/0001 12:00:00 AM
DateTime dt = DateTime.Now;// gives today date with current time
DateTime dt = DateTime.Today;// gives today date and 12:00:00 AM time

If you want to add a row into the tbody, get a reference to it and call its insertRow method.

var tbodyRef = document.getElementById('myTable').getElementsByTagName('tbody')[0];

// Insert a row at the end of table
var newRow = tbodyRef.insertRow();

// Insert a cell at the end of the row
var newCell = newRow.insertCell();

// Append a text node to the cell
var newText = document.createTextNode('new row');
newCell.appendChild(newText);

<table id="myTable">
  <thead>
    <tr>
      <th>My Header</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>initial row</td>
    </tr>
  </tbody>
  <tfoot>
    <tr>
      <td>My Footer</td>
    </tr>
  </tfoot>
</table>

Arrays

• Set, Check element at a particular index: O(1)
• Searching: O(n) if array is unsorted and O(log n) if array is sorted and something like a binary search is used,
• As pointed out by Aivean, there is no Delete operation available on Arrays. We can symbolically delete an element by setting it to some specific value, e.g. -1, 0, etc. depending on our requirements
• Similarly, Insert for arrays is basically Set as mentioned in the beginning

ArrayList:

• Add: Amortized O(1)
• Remove: O(n)
• Contains: O(n)
• Size: O(1)

Linked List:

• Inserting: O(1), if done at the head, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Deleting: O(1), if done at the head, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Searching: O(n)

Doubly-Linked List:

• Inserting: O(1), if done at the head or tail, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Deleting: O(1), if done at the head or tail, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Searching: O(n)

Stack:

• Push: O(1)
• Pop: O(1)
• Top: O(1)
• Search (Something like lookup, as a special operation): O(n) (I guess so)

Queue/Deque/Circular Queue:

• Insert: O(1)
• Remove: O(1)
• Size: O(1)

Binary Search Tree:

• Insert, delete and search: Average case: O(log n), Worst Case: O(n)

Red-Black Tree:

• Insert, delete and search: Average case: O(log n), Worst Case: O(log n)

Heap/PriorityQueue (min/max):

• Find Min/Find Max: O(1)
• Insert: O(log n)
• Delete Min/Delete Max: O(log n)
• Extract Min/Extract Max: O(log n)
• Lookup, Delete (if at all provided): O(n), we will have to scan all the elements as they are not ordered like BST

HashMap/Hashtable/HashSet:

• Insert/Delete: O(1) amortized
• Re-size/hash: O(n)
• Contains: O(1)

I use the suffixes option in .merge():

dfNew = df.merge(df2, left_index=True, right_index=True,
                 how='outer', suffixes=('', '_y'))
dfNew.drop(dfNew.filter(regex='_y$').columns.tolist(),axis=1, inplace=True)

@Controller returns View. @RestController returns ResponseBody.

The Apache filter is built for iterating files in a known directory. To allow wildcards in the directory also, you would have to split the path on '\' or '/' and do a filter on each part separately.

I guess you should differentiate the target (before and after Oreo)

int LAYOUT_FLAG;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
} else {
    LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_PHONE;
}

params = new WindowManager.LayoutParams(
    WindowManager.LayoutParams.WRAP_CONTENT,
    WindowManager.LayoutParams.WRAP_CONTENT,
    LAYOUT_FLAG,
    WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
    PixelFormat.TRANSLUCENT);

By entering $PATH on its own at the command prompt, you're trying to run it. This isn't like Windows where you can get your path output by simply typing path.

If you want to see what the path is, simply echo it:

echo $PATH

Use the FULL path to the folder in your If Not Exist code. Then you won't even have to CD anymore:

If Not Exist "C:\Documents and Settings\John\Start Menu\Programs\SoftWareFolder\"

<html>
  <head>
    <title>Example Using Google Complete API</title>

  <body>

<form>
   <input id="geocomplete" type="text" placeholder="Type an address/location"/>

No need to be that hardcore.
Try this :

YourButtonObject.setBackground(0xff99cc00);

If you loaded the resource using the visual studio UI, then you should be able to do this:

picturebox.Image = project.Properties.Resources.imgfromresource
