YearMonth

For completeness, and more elegant in my opinion, see this use of YearMonth class.

YearMonth month = YearMonth.from(date);
LocalDate start = month.atDay(1);
LocalDate end   = month.atEndOfMonth();

For the first & last day of the current month, this becomes:

LocalDate start = YearMonth.now().atDay(1);
LocalDate end   = YearMonth.now().atEndOfMonth();

I need to do this frequently, so I use this:

var loadJS = function(url, implementationCode, location){
    //url is URL of external file, implementationCode is the code
    //to be called from the file, location is the location to 
    //insert the <script> element

    var scriptTag = document.createElement('script');
    scriptTag.src = url;

    scriptTag.onload = implementationCode;
    scriptTag.onreadystatechange = implementationCode;

    location.appendChild(scriptTag);
};
var yourCodeToBeCalled = function(){
//your code goes here
}
loadJS('yourcode.js', yourCodeToBeCalled, document.body);

For more information, see this site How do I include a JavaScript file in another JavaScript file?, which is the source of my function idea.

It worked i used userdell --force USERNAME Some times eventhough -f and --force is same -f is not working sometimes After i removed the account i exit back to that removed username which i removed from root then what happened is this

Try this:

SELECT * 
FROM information_schema.KEY_COLUMN_USAGE 
WHERE REFERENCED_TABLE_NAME = 'YourTable';

This should deliver you which Tables have references to the table you want to drop, once you drop these references, or the datasets which reference datasets in this table you will be able to drop the table

Just add this section to server, just before the location / {

location /your/folder/to/browse/ {
        autoindex on;
}

In Typescript - app.component.ts file

export class AppComponent implements OnInit {
    currentDate = new Date();
}

In HTML Input field

<input id="form21_1" type="text" tabindex="28" title="DATE" [ngModel]="currentDate | date:'MM/dd/yyyy'" />

It will display the current date inside the input field.

One of the biggest reasons that C++ doesn't have built in garbage collection is that getting garbage collection to play nice with destructors is really, really hard. As far as I know, nobody really knows how to solve it completely yet. There are alot of issues to deal with:

• deterministic lifetimes of objects (reference counting gives you this, but GC doesn't. Although it may not be that big of a deal).
• what happens if a destructor throws when the object is being garbage collected? Most languages ignore this exception, since theres really no catch block to be able to transport it to, but this is probably not an acceptable solution for C++.
• How to enable/disable it? Naturally it'd probably be a compile time decision but code that is written for GC vs code that is written for NOT GC is going to be very different and probably incompatible. How do you reconcile this?

These are just a few of the problems faced.

This post helped me come up with a similar solution for my own purposes:

MESSAGE=`{ echo $ERROR_MESSAGE | format_logs.py --level=ERROR; } 2>&1`

Then as long as our MESSAGE is not an empty string, we pass it on to other stuff. This will let us know if our format_logs.py failed with some kind of python exception.

These are the meanings:

401: User not (correctly) authenticated, the resource/page require authentication

403: User authenticated, but his role or permissions does not allow to access requested resource, for instance user is not an administrator and requested page is for administrators

Under Windows for me this works:

virtualenv --python=c:\Python25\python.exe envname

without the python.exe I got WindowsError: [Error 5] Access is denied I have Python2.7.1 installed with virtualenv 1.6.1, and I wanted python 2.5.2.

You can also do it in a three line method:

public static int gcd(int x, int y){
  return (y == 0) ? x : gcd(y, x % y);
}

Here, if y = 0, x is returned. Otherwise, the gcd method is called again, with different parameter values.

One option is to bind a handler to the input event.

The advantage of this approach is that we don't prevent keyboard behaviors that the user expects (e.g. tab, page up/down, etc.).

Another advantage is that it also handles the case when the input value is changed by pasting text through the context menu.

This approach works best if you only care about keeping the input empty. If you want to maintain a specific value, you'll have to track that somewhere else (in a data attribute?) since it will not be available when the input event is received.

const inputEl = document.querySelector('input');_x000D_
_x000D_
inputEl.addEventListener('input', (event) => {_x000D_
  event.target.value = '';_x000D_
});

<input type="text" />

The solution I posted on Dev and worked for most people using React:

comm -23 <(ls dir1 |sort) <(ls dir2|sort)

This command will give you files those are in dir1 and not in dir2.

About <( ) sign, you can google it as 'process substitution'.

This helped me:

<p>Date/Time: <span id="datetime"></span></p><script>var dt = new Date();
document.getElementById("datetime").innerHTML=dt.toLocaleString();</script>    

Using String.prototype.replace with regex, as mentioned in the other answers, is certainly the best solution.

But, just for fun, you can also remove all whitespaces from a text by using String.prototype.split and String.prototype.join:

const text = ' a b    c d e   f g   ';_x000D_
const newText = text.split(/\s/).join('');_x000D_
_x000D_
console.log(newText); // prints abcdefg

MVC's anti-forgery support writes a unique value to an HTTP-only cookie and then the same value is written to the form. When the page is submitted, an error is raised if the cookie value doesn't match the form value.

It's important to note that the feature prevents cross site request forgeries. That is, a form from another site that posts to your site in an attempt to submit hidden content using an authenticated user's credentials. The attack involves tricking the logged in user into submitting a form, or by simply programmatically triggering a form when the page loads.

The feature doesn't prevent any other type of data forgery or tampering based attacks.

To use it, decorate the action method or controller with the ValidateAntiForgeryToken attribute and place a call to @Html.AntiForgeryToken() in the forms posting to the method.

As an alternative, there's a nice 3rd party library designed just for this use case. Whereby you need to generate headers based on the data being stored in the adapter. They are called Rolodex adapters and are used with ExpandableListViews. They can easily be customized to behave like a normal list with headers.

Using the OP's Event objects and knowing the headers are based on the Date associated with it...the code would look something like this:

The Activity

    //There's no need to pre-compute what the headers are. Just pass in your List of objects. 
    EventDateAdapter adapter = new EventDateAdapter(this, mEvents);
    mExpandableListView.setAdapter(adapter);

The Adapter

private class EventDateAdapter extends NFRolodexArrayAdapter<Date, Event> {

    public EventDateAdapter(Context activity, Collection<Event> items) {
        super(activity, items);
    }

    @Override
    public Date createGroupFor(Event childItem) {
        //This is how the adapter determines what the headers are and what child items belong to it
        return (Date) childItem.getDate().clone();
    }

    @Override
    public View getChildView(LayoutInflater inflater, int groupPosition, int childPosition,
                             boolean isLastChild, View convertView, ViewGroup parent) {
        //Inflate your view

        //Gets the Event data for this view
        Event event = getChild(groupPosition, childPosition);

        //Fill view with event data
    }

    @Override
    public View getGroupView(LayoutInflater inflater, int groupPosition, boolean isExpanded,
                             View convertView, ViewGroup parent) {
        //Inflate your header view

        //Gets the Date for this view
        Date date = getGroup(groupPosition);

        //Fill view with date data
    }

    @Override
    public boolean hasAutoExpandingGroups() {
        //This forces our group views (headers) to always render expanded.
        //Even attempting to programmatically collapse a group will not work.
        return true;
    }

    @Override
    public boolean isGroupSelectable(int groupPosition) {
        //This prevents a user from seeing any touch feedback when a group (header) is clicked.
        return false;
    }
}

If we have a single server we can directly include it in the proxy_pass. But in case if we have many servers we use upstream to maintain the servers. Nginx will load-balance based on the incoming traffic.

No. Java literal null is not an instance of any class. Therefore it can not be an instanceof any class. instanceof will return either false or true therefore the <referenceVariable> instanceof <SomeClass> returns false when referenceVariable value is null.

Similar to laszlo answer but you can reuse the same prototype cell for both the table cells and the section header cell. Add the first two functions below to your UIViewController subClass

override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let cell = tableView.dequeueReusableCell(withIdentifier: "DataCell") as! DataCell
    cell.data1Label.text = "DATA KEY"
    cell.data2Label.text = "DATA VALUE"
    return cell
}

override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    return 75
}

// Example of regular data cell dataDelegate to round out the example
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "DataCell", for: indexPath) as! PlayerCell

    cell.data1Label.text = "\(dataList[indexPath.row].key)"
    cell.data2Label.text = "\(dataList[indexPath.row].value)"
    return cell
}

I removed Android dependencies from build path and it worked.

Edit: ignore that. I had same jar in my maven dependencies and libs folder. I removed the one at the lib folder.

Something along the lines of (using JSTL):

<p>Selected Values:
<ul>
  <c:forEach items="${paramValues['select2']}" var="selectedValue">
    <li><c:out value="${selectedValue}" /></li>
  </c:forEach>
</ul>
</p>

I got this error too. I figured out that my version of PHP didn't have openssl compiled in, so simply adding the extension directive to php.ini wasn't enough. I don't know how you have to solve this in your particular case, but for me, I use macports, and the command was just:

sudo port install php5-openssl

Another possibility is:

d = datetime.datetime.utcnow()
epoch = datetime.datetime(1970,1,1)
t = (d - epoch).total_seconds()

This works as both "d" and "epoch" are naive datetimes, making the "-" operator valid, and returning an interval. total_seconds() turns the interval into seconds. Note that total_seconds() returns a float, even d.microsecond == 0

As far as I am aware no function exists to return this, you will have to hard set it.

Attempting to cast from values such as 0 to get a minimum date will default to 01-01-1900.

As suggested previously best left set to NULL (and use ISNULL when reading if you need to), or if you are worried about setting it correctly you could even set a trigger on the table to set your modified date on edits.

If you have your heart set on getting the minimum possible date then:

create table atable
(
  atableID int IDENTITY(1, 1) PRIMARY KEY CLUSTERED,
  Modified datetime DEFAULT '1753-01-01'
)

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

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

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

If you want to use valueChangeListener, you need to submit the form every time a new option is chosen. Something like this:

<p:selectOneMenu value="#{mymb.employee}" onchange="submit()"
                 valueChangeListener="#{mymb.handleChange}" >
    <f:selectItems value="#{mymb.employeesList}" var="emp"
                   itemLabel="#{emp.employeeName}" itemValue="#{emp.employeeID}" />
</p:selectOneMenu>

public void handleChange(ValueChangeEvent event){  
    System.out.println("New value: " + event.getNewValue());
}

Or else, if you want to use <p:ajax>, it should look like this:

<p:selectOneMenu value="#{mymb.employee}" >
    <p:ajax listener="#{mymb.handleChange}" />
    <f:selectItems value="#{mymb.employeesList}" var="emp"
                   itemLabel="#{emp.employeeName}" itemValue="#{emp.employeeID}" />
</p:selectOneMenu>

private String employeeID;

public void handleChange(){  
    System.out.println("New value: " + employee);
}

One thing to note is that in your example code, I saw that the value attribute of your <p:selectOneMenu> is #{mymb.employeesList} which is the same as the value of <f:selectItems>. The value of your <p:selectOneMenu> should be similar to my examples above which point to a single employee, not a list of employees.

@SimonBuchan is correct.

Since git 1.8.2, Resources/** !Resources/**/*.foo works.

You can also set the width to a percentage (or a ratio) for a dynamic size. Absolute size is still accepted.

function popupWindow(url, title, w='75%', h='16:9', opts){
    // sort options
    let options = [];
    if(typeof opts === 'object'){
        Object.keys(opts).forEach(function(value, key){
            if(value === true){value = 'yes';}else if(value === false){value = 'no';}
            options.push(`${key}=${value}`);
        });
        if(options.length){options = ','+options.join(',');}
        else{options = '';}
    }else if(Array.isArray(opts)){
        options = ','+opts.join(',');
    }else if(typeof opts === 'string'){
        options = ','+opts;
    }else{options = '';}

    // add most vars to local object (to shorten names)
    let size = {w: w, h: h};
    let win = {w: {i: window.top.innerWidth, o: window.top.outerWidth}, h: {i: window.top.innerHeight, o: window.top.outerHeight}, x: window.top.screenX || window.top.screenLeft, y: window.top.screenY || window.top.screenTop}

    // set window size if percent
    if(typeof size.w === 'string' && size.w.endsWith('%')){size.w = Number(size.w.replace(/%$/, ''))*win.w.o/100;}
    if(typeof size.h === 'string' && size.h.endsWith('%')){size.h = Number(size.h.replace(/%$/, ''))*win.h.o/100;}

    // set window size if ratio
    if(typeof size.w === 'string' && size.w.includes(':')){
        size.w = size.w.split(':', 2);
        if(win.w.o < win.h.o){
            // if height is bigger than width, reverse ratio
            size.w = Number(size.h)*Number(size.w[1])/Number(size.w[0]);
        }else{size.w = Number(size.h)*Number(size.w[0])/Number(size.w[1]);}
    }
    if(typeof size.h === 'string' && size.h.includes(':')){
        size.h = size.h.split(':', 2);
        if(win.w.o < win.h.o){
            // if height is bigger than width, reverse ratio
            size.h = Number(size.w)*Number(size.h[0])/Number(size.h[1]);
        }else{size.h = Number(size.w)*Number(size.h[1])/Number(size.h[0]);}
    }

    // force window size to type number
    if(typeof size.w === 'string'){size.w = Number(size.w);}
    if(typeof size.h === 'string'){size.h = Number(size.h);}

    // keep popup window within padding of window size
    if(size.w > win.w.i-50){size.w = win.w.i-50;}
    if(size.h > win.h.i-50){size.h = win.h.i-50;}

    // do math
    const x = win.w.o / 2 + win.x - (size.w / 2);
    const y = win.h.o / 2 + win.y - (size.h / 2);
    return window.open(url, title, `width=${size.w},height=${size.h},left=${x},top=${y}${options}`);
}

usage:

// width and height are optional (defaults: width = '75%' height = '16:9')
popupWindow('https://www.google.com', 'Title', '75%', '16:9', {/* options (optional) */});

// options can be an object, array, or string

// example: object (only in object, true/false get replaced with 'yes'/'no')
const options = {scrollbars: false, resizable: true};

// example: array
const options = ['scrollbars=no', 'resizable=yes'];

// example: string (same as window.open() string)
const options = 'scrollbars=no,resizable=yes';

Yes, I think hashing the file would be the best way if you have to compare several files and store hashes for later comparison. As hash can clash, a byte-by-byte comparison may be done depending on the use case.

Generally byte-by-byte comparison would be sufficient and efficient, which filecmp module already does + other things too.

See http://docs.python.org/library/filecmp.html e.g.

>>> import filecmp
>>> filecmp.cmp('file1.txt', 'file1.txt')
True
>>> filecmp.cmp('file1.txt', 'file2.txt')
False

Speed consideration: Usually if only two files have to be compared, hashing them and comparing them would be slower instead of simple byte-by-byte comparison if done efficiently. e.g. code below tries to time hash vs byte-by-byte

Disclaimer: this is not the best way of timing or comparing two algo. and there is need for improvements but it does give rough idea. If you think it should be improved do tell me I will change it.

import random
import string
import hashlib
import time

def getRandText(N):
    return  "".join([random.choice(string.printable) for i in xrange(N)])

N=1000000
randText1 = getRandText(N)
randText2 = getRandText(N)

def cmpHash(text1, text2):
    hash1 = hashlib.md5()
    hash1.update(text1)
    hash1 = hash1.hexdigest()

    hash2 = hashlib.md5()
    hash2.update(text2)
    hash2 = hash2.hexdigest()

    return  hash1 == hash2

def cmpByteByByte(text1, text2):
    return text1 == text2

for cmpFunc in (cmpHash, cmpByteByByte):
    st = time.time()
    for i in range(10):
        cmpFunc(randText1, randText2)
    print cmpFunc.func_name,time.time()-st

and the output is

cmpHash 0.234999895096
cmpByteByByte 0.0

The Subject, in security, is the thing being secured. In this case it could be a persons email or a website or a machine.

If we take the example of an email, say my email, then the subject key container would be the protected location containing my private key.

The certificate store usually refers to Microsoft certificate store which contains certificates form trusted roots, machines on the network, people etc. In my case the subjects certificate store would be the place, within this store, holding my certificates.

If you are working within a microsoft domain then the subject name will invariably hold the Distinguished Name, of the subject, which is how the domain references the subject and holds it in its directory. e.g. CN=Mark Sutton, OU=Developers, O=Mycompany C=UK

To look at your certificates on a microsoft machine:-

Log in as you run>mmc Select File>add/remove snap-in and select certificates then select my user account click Finish then close then ok. Look in the personal area of the store.

In the other areas of the store you will see the other trusted certificates used to validate signatures etc.

I mean it's quite simple. Set it as a double. So lets say

I would like to hint on q2o. It is a JPA based Java object mapper which helps with many of the tedious SQL and JDBC ResultSet related tasks, but without all the complexity an ORM framework comes with. With its help mapping a ResultSet to an object is as easy as this:

while(rs.next()) {
    users.add(Q2Obj.fromResultSet(rs, User.class));
}

More about q2o can be found here.

You can use:

adb shell monkey -p com.package.name -c android.intent.category.LAUNCHER 1

This will start the LAUNCHER Activity of the application using monkeyrunner test tool.

If you know the (maximum) number of rows and columns beforehand, you can use resize() to initialize a vector of vectors and then modify (and access) elements with operator[]. Example:

int no_of_cols = 5;
int no_of_rows = 10;
int initial_value = 0;

std::vector<std::vector<int>> matrix;
matrix.resize(no_of_rows, std::vector<int>(no_of_cols, initial_value));

// Read from matrix.
int value = matrix[1][2];

// Save to matrix.
matrix[3][1] = 5;

Another possibility is to use just one vector and split the id in several variables, access like vector[(row * columns) + column].

Colin Pickard is mostly correct, but don't confuse the "password to open" protection for the entire file with the VBA password protection, which is completely different from the former and is the same for Office 2003 and 2007 (for Office 2007, rename the file to .zip and look for the vbaProject.bin inside the zip). And that technically the correct way to edit the file is to use a OLE compound document viewer like CFX to open up the correct stream. Of course, if you are just replacing bytes, the plain old binary editor may work.

BTW, if you are wondering about the exact format of these fields, they have it documented now:

If you have a non-printing character at the front of the string try this

Option Explicit
Sub DoTrim()
    Dim cell As Range
    Dim str As String
    Dim nAscii As Integer
    For Each cell In Selection.Cells
        If cell.HasFormula = False Then
            str = Trim(CStr(cell))
            If Len(str) > 0 Then
                nAscii = Asc(Left(str, 1))
                If nAscii < 33 Or nAscii = 160 Then
                    If Len(str) > 1 Then
                        str = Right(str, Len(str) - 1)
                    Else
                        strl = ""
                    End If
                End If
            End If

The property event.which is added when using jQuery to avoid browser differences. See docs.

The which property will be undefined if you are not using jQuery.

Looking at the internets there can be various of causes. In my case leaving everything default except...

apc.shm_size = 64M

...cleared the countless warnings that I was getting earlier.

in addition: for those who have a empty POST variable, don't use this:

name="[levels][level][]"

rather use this (as it is already here in this example):

name="levels[level][]"

To get the number of votes for a specific item, you would use:

vote_count = Item.objects.filter(votes__contest=contestA).count()

If you wanted a break down of the distribution of votes in a particular contest, I would do something like the following:

contest = Contest.objects.get(pk=contest_id)
votes   = contest.votes_set.select_related()

vote_counts = {}

for vote in votes:
  if not vote_counts.has_key(vote.item.id):
    vote_counts[vote.item.id] = {
      'item': vote.item,
      'count': 0
    }

  vote_counts[vote.item.id]['count'] += 1

This will create dictionary that maps items to number of votes. Not the only way to do this, but it's pretty light on database hits, so will run pretty quickly.

Bonus: why do people seemingly always use big-oh when talking informally?

Because in big-oh, this loop:

for i = 1 to n do
    something in O(1) that doesn't change n and i and isn't a jump

is O(n), O(n^2), O(n^3), O(n^1423424). big-oh is just an upper bound, which makes it easier to calculate because you don't have to find a tight bound.

The above loop is only big-theta(n) however.

What's the complexity of the sieve of eratosthenes? If you said O(n log n) you wouldn't be wrong, but it wouldn't be the best answer either. If you said big-theta(n log n), you would be wrong.

\ is used as for escape sequence in many programming languages, including Java.

If you want to

• go to next line then use \n or \r,
• for tab use \t
• likewise to print a \ or " which are special in string literal you have to escape it with another \ which gives us \\ and \"

Colon does not have special meaning in a character class and does not need to be escaped. According to the PHP regex docs, the only characters that need to be escaped in a character class are the following:

All non-alphanumeric characters other than \, -, ^ (at the start) and the terminating ] are non-special in character classes, but it does no harm if they are escaped.

For more info about Java regular expressions, see the docs.

You don't encode the entire URL, only parts of it that come from "unreliable sources".

• Java:

  String query = URLEncoder.encode("apples oranges", "utf-8");
  String url = "http://stackoverflow.com/search?q=" + query;
  

• Kotlin:

  val query: String = URLEncoder.encode("apples oranges", "utf-8")
  val url = "http://stackoverflow.com/search?q=$query"
  

Alternatively, you can use Strings.urlEncode(String str) of DroidParts that doesn't throw checked exceptions.

Or use something like

String uri = Uri.parse("http://...")
                .buildUpon()
                .appendQueryParameter("key", "val")
                .build().toString();

Here is generic labels width for all form labels. Nothing fix width.

call setLabelWidth calculator with all the labels. This function will load all labels on UI and find out maximum label width. Apply return value of below function to all the labels.

     this.setLabelWidth = function (labels) {
            var d = labels.join('<br>'),
                dummyelm = jQuery("#lblWidthCalcHolder"),
                width;
            dummyelm.empty().html(d);
            width = Math.ceil(dummyelm[0].getBoundingClientRect().width);
            width = width > 0 ? width + 5: width;
            //this.resetLabels(); //to reset labels.
            var element = angular.element("#lblWidthCalcHolder")[0];
            element.style.visibility = "hidden";
            //Removing all the lables from the element as width is calculated and the element is hidden
            element.innerHTML = "";
            return {
                width: width,
                validWidth: width !== 0
            };

        };

InputStream is;
InputStreamReader r = new InputStreamReader(is);
BufferedReader br = new BufferedReader(r);

Do you really need to load it from a file? If you place it along your classes (in WEB-INF/classes) you can get an InputStream to it using the class loader:

InputStream csv = 
   SomeClassInTheSamePackage.class.getResourceAsStream("filename.csv");

ConnectivityAction is deprecated in api 28+. Instead you can use registerDefaultNetworkCallback as long as you support api 24+.

In Kotlin:

val connectivityManager = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
connectivityManager?.let {
    it.registerDefaultNetworkCallback(object : ConnectivityManager.NetworkCallback() {
        override fun onAvailable(network: Network) {
            //take action when network connection is gained
        }
        override fun onLost(network: Network?) {
            //take action when network connection is lost
        }
    })
}

In the hypothetical situation where you could perform a potentially expensive non-const operation on an object, returning by const-value prevents you from accidentally calling this operation on a temporary. Imagine that + returned a non-const value, and you could write:

(a + b).expensive();

In the age of C++11, however, it is strongly advised to return values as non-const so that you can take full advantage of rvalue references, which only make sense on non-constant rvalues.

In summary, there is a rationale for this practice, but it is essentially obsolete.

I really wish I'd known that you can use CtrlC instead of Esc to switch out of insert mode. That's been a real productivity boost for me.

There is the data.table approach for an inner join, which is very time and memory efficient (and necessary for some larger data.frames):

library(data.table)

dt1 <- data.table(df1, key = "CustomerId") 
dt2 <- data.table(df2, key = "CustomerId")

joined.dt1.dt.2 <- dt1[dt2]

merge also works on data.tables (as it is generic and calls merge.data.table)

merge(dt1, dt2)

data.table documented on stackoverflow:
How to do a data.table merge operation
Translating SQL joins on foreign keys to R data.table syntax
Efficient alternatives to merge for larger data.frames R
How to do a basic left outer join with data.table in R?

Yet another option is the join function found in the plyr package

library(plyr)

join(df1, df2,
     type = "inner")

#   CustomerId Product   State
# 1          2 Toaster Alabama
# 2          4   Radio Alabama
# 3          6   Radio    Ohio

Options for type: inner, left, right, full.

From ?join: Unlike merge, [join] preserves the order of x no matter what join type is used.

This is a tool to open Java class file binaries, view their internal structure, modify portions of it if required and save the class file back. It also generates readable reports similar to the javap utility. Easy to use Java Swing GUI. The user interface tries to display as much detail as possible and tries to present a structure as close as the actual Java class file structure. At the same time ease of use and class file consistency while doing modifications is also stressed. For example, when a method is deleted, the associated constant pool entry will also be deleted if it is no longer referenced. In built verifier checks changes before saving the file. This tool has been used by people learning Java class file internals. This tool has also been used to do quick modifications in class files when the source code is not available." this is a quote from the website.

http://classeditor.sourceforge.net/

This is your javascript file:

function yourFunction(){
     document.getElementById('yourid').value = "";
};

This is the html file:

    <textarea id="yourid" >
    Your text inside the textarea
    </textarea>
    <button onClick="yourFunction();">
     Your button Name
     </button>

According to http://www.techotopia.com/index.php/Ruby_String_Concatenation_and_Comparison

Doing either

mystring == yourstring

or

mystring.eql? yourstring

Are equivalent.

There are some issues worth noticing if you're dealing with classes that are persisted using an Object-Relationship Mapper (ORM) like Hibernate, if you didn't think this was unreasonably complicated already!

Lazy loaded objects are subclasses

If your objects are persisted using an ORM, in many cases you will be dealing with dynamic proxies to avoid loading object too early from the data store. These proxies are implemented as subclasses of your own class. This means thatthis.getClass() == o.getClass() will return false. For example:

Person saved = new Person("John Doe");
Long key = dao.save(saved);
dao.flush();
Person retrieved = dao.retrieve(key);
saved.getClass().equals(retrieved.getClass()); // Will return false if Person is loaded lazy

If you're dealing with an ORM, using o instanceof Person is the only thing that will behave correctly.

Lazy loaded objects have null-fields

ORMs usually use the getters to force loading of lazy loaded objects. This means that person.name will be null if person is lazy loaded, even if person.getName() forces loading and returns "John Doe". In my experience, this crops up more often in hashCode() and equals().

If you're dealing with an ORM, make sure to always use getters, and never field references in hashCode() and equals().

Saving an object will change its state

Persistent objects often use a id field to hold the key of the object. This field will be automatically updated when an object is first saved. Don't use an id field in hashCode(). But you can use it in equals().

A pattern I often use is

if (this.getId() == null) {
    return this == other;
}
else {
    return this.getId().equals(other.getId());
}

But: you cannot include getId() in hashCode(). If you do, when an object is persisted, its hashCode changes. If the object is in a HashSet, you'll "never" find it again.

In my Person example, I probably would use getName() for hashCode and getId() plus getName() (just for paranoia) for equals(). It's okay if there are some risk of "collisions" for hashCode(), but never okay for equals().

hashCode() should use the non-changing subset of properties from equals()

Angular 8. Check whether the current route is the base route.

  baseroute: boolean;
  constructor(

    router.events.subscribe((val: any) => {
      if (val.url == "/") {
        this.baseroute = true;
      } else {
        this.baseroute = false;
      }
    });
  }

If you need a CakePHP Docker Container with MySQL, I have created a Docker image for that purpose! No need to worry about setting it up. It just works!

• GitHub: https://github.com/marcellodesales/php-apache-mysql-4-cakephp-docker
• DockerHub: https://hub.docker.com/r/marcellodesales/php-apache-cakephp-mysql/

Here's how I installed in Ubuntu-based image:

https://github.com/marcellodesales/php-apache-mysql-4-cakephp-docker/blob/master/Dockerfile#L8

RUN docker-php-ext-install mysql mysqli pdo pdo_mysql

Building and running your application is just a 2 step process (considering you are in the current directory of the app):

$ docker build -t myCakePhpApp .
$ docker run -ti myCakePhpApp

First off, you have to specify you wish to use Document Literal style:

$client = new SoapClient(NULL, array(
    'location' => 'https://example.com/path/to/service',
    'uri' => 'http://example.com/wsdl',
    'trace' => 1,
    'use' => SOAP_LITERAL)
);

Then, you need to transform your data into a SoapVar; I've written a simple transform function:

function soapify(array $data)
{
        foreach ($data as &$value) {
                if (is_array($value)) {
                        $value = soapify($value);
                }
        }

        return new SoapVar($data, SOAP_ENC_OBJECT);
}

Then, you apply this transform function onto your data:

$data = soapify(array(
    'Acquirer' => array(
        'Id' => 'MyId',
        'UserId' => 'MyUserId',
        'Password' => 'MyPassword',
    ),
));

Finally, you call the service passing the Data parameter:

$method = 'Echo';

$result = $client->$method(new SoapParam($data, 'Data'));

You need to subscribe to the observable and pass a callback that processes emitted values

this.myService.getConfig().subscribe(val => console.log(val));

With momentjs "fromNow" method, This allows you to work with formatted date, ie: 03/15/1968

var dob = document.getElementByID("dob"); var age = moment(dob.value).fromNow(true).replace(" years", "");

//fromNow(true) => suffix "ago" is not displayed //but we still have to get rid of "years";

As a prototype version

String.prototype.getAge = function() {
return moment(this.valueOf()).fromNow(true).replace(" years", "");

}

Caution: This answer provides a solution that was relevant at that time, before the new features of MongoDB 2.2 and up were introduced. See the other answers if you are using a more recent version of MongoDB.

The field selector parameter is limited to complete properties. It cannot be used to select part of an array, only the entire array. I tried using the $ positional operator, but that didn't work.

The easiest way is to just filter the shapes in the client.

If you really need the correct output directly from MongoDB, you can use a map-reduce to filter the shapes.

function map() {
  filteredShapes = [];

  this.shapes.forEach(function (s) {
    if (s.color === "red") {
      filteredShapes.push(s);
    }
  });

  emit(this._id, { shapes: filteredShapes });
}

function reduce(key, values) {
  return values[0];
}

res = db.test.mapReduce(map, reduce, { query: { "shapes.color": "red" } })

db[res.result].find()

You could do this:

SELECT * FROM table WHERE cast(YOUR_INTEGER_VALUE as varchar) = 'string of numbers'

Use android vollley, it is very fast and you can betterm manipulate requests. Send post request using Volley and receive in PHP

Basically, you will create a map with key-value params for the php request(POST/GET), the php will do the desired processing and you will return the data as JSON(json_encode()). Then you can either parse the JSON as needed or use GSON from Google to let it do the parsing.

You can use jackson library and simply use these 3 lines to convert your json file to Java Object.

ObjectMapper mapper = new ObjectMapper();
InputStream is = Test.class.getResourceAsStream("/test.json");
testObj = mapper.readValue(is, Test.class);

The system default values of 0.25 for duration and .curveEaseInEaseOut for timingFunction are often preferable for consistency across animations, and can be omitted:

let animation = CATransition()
label.layer.add(animation, forKey: nil)
label.text = "New text"

which is the same as writing this:

let animation = CATransition()
animation.duration = 0.25
animation.timingFunction = .curveEaseInEaseOut
label.layer.add(animation, forKey: nil)
label.text = "New text"

Please see this.

Text inside a CDATA section will be ignored by the parser.

There is already a string handling function Series.str.startswith(). You should try foo[foo.b.str.startswith('f')].

Result:

    a   b
1   2   foo
2   3   fat

I think what you expect.

Alternatively you can use contains with regex option. For example:

foo[foo.b.str.contains('oo', regex= True, na=False)]

Result:

    a   b
1   2   foo

na=False is to prevent Errors in case there is nan, null etc. values

Your problem is this

<button type="button" value=" Send" class="btn btn-success" type="submit" id="submit" />

You've set the type twice. Your browser is only accepting the first, which is "button".

<button type="submit" value=" Send" class="btn btn-success" id="submit" />

Here is a NuGet plugin called Cassette, which among other things provides you the ability to reference scripts and styles in partials.

Though there are a number of configurations available for this plugin, which makes it highly flexible. Here is the simplest way of referring script or stylesheet files:

Bundles.Reference("scripts/app");

According to the documentation:

Calls to Reference can appear anywhere in a page, layout or partial view.

The path argument can be one of the following:

• A bundle path
• An asset path - the whole bundle containing this asset is referenced
• A URL

From info gcc (emphasis mine):

-ansi

In C mode, this is equivalent to -std=c90. In C++ mode, it is equivalent to -std=c++98. This turns off certain features of GCC that are incompatible with ISO C90 (when compiling C code), or of standard C++ (when compiling C++ code), such as the asm and typeof keywords, and predefined macros such as 'unix' and 'vax' that identify the type of system you are using. It also enables the undesirable and rarely used ISO trigraph feature. For the C compiler, it disables recognition of C++ style // comments as well as the inline keyword.

(It uses vax in the example instead of linux because when it was written maybe it was more popular ;-).

The basic idea is that GCC only tries to fully comply with the ISO standards when it is invoked with the -ansi option.

Lazy loading - is good when handling with pagination like on page load list of users appear which contains 10 users and as the user scrolls down the page an api call brings next 10 users.Its good when you don't want to load enitire data at once as it would take more time and would give bad user experience.

Eager loading - is good as other people suggested when there are not much relations and fetch entire data at once in single call to database

Sometimes you may be running code on a virtual server elsewhere - That can get muddy when running NODEJS or other flavors.

Here is a fix that will allow you to use any timezone easily.

Check here for list of timezones

let myFormattedDateTime = date.format(dd, 'YYYY/MM/DD HH:mm:ss A [America/New_York]Z');
let myFormattedDateTime24 = date.format(dd, 'YYYY/MM/DD HH:mm:ss [America/New_York]Z');

On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files. Be very careful to use binary mode when reading and writing such files. On Unix, it doesn’t hurt to append a 'b' to the mode, so you can use it platform-independently for all binary files.

That is actually the declaration for an event handler - a method that will get called when an event is fired. To create an event, you'd write something like this:

public class Foo
{
    public event EventHandler MyEvent;
}

And then you can subscribe to the event like this:

Foo foo = new Foo();
foo.MyEvent += new EventHandler(this.OnMyEvent);

With OnMyEvent() defined like this:

private void OnMyEvent(object sender, EventArgs e)
{
    MessageBox.Show("MyEvent fired!");
}

Whenever Foo fires off MyEvent, then your OnMyEvent handler will be called.

You don't always have to use an instance of EventArgs as the second parameter. If you want to include additional information, you can use a class derived from EventArgs (EventArgs is the base by convention). For example, if you look at some of the events defined on Control in WinForms, or FrameworkElement in WPF, you can see examples of events that pass additional information to the event handlers.

The project facets should be derived automagically by the M2Eclipse plugin from the POM configuration. If you make some changes to the POM and need Eclipse to take them into account, right-click on your project, then go to Maven > Update Project Configuration. You should not set project facets manually.

Steps to Remove app from App Store

1. Click the My Apps section.
2. Select the app you'd like to remove.
3. Click the Pricing tab from the app listing page.
4. Click the "specific territories" link.
5. In the drop-down section that appears below, click "Deselect All' at the top right. This will uncheck every territory below.
6. A confirmation message will appear at the top of the screen.
7. Return to the My Apps section by clicking the navigation button at the top left.
8. The application status has changed to "Developer Removed From Sale."
9. Within 24 hours (though usually less) your app will no longer appear in the App Store.

You don't tend to execute the make file itself, rather you execute make, giving it the make file as an argument:

make -f pax.mk

If your make file is actually one of the standard names (like makefile or Makefile), you don't even need to specify it. It'll be picked up by default (if you have more than one of these standard names in your build directory, you better look up the make man page to see which takes precedence).

If you do not want to use Docker Compose, I can recommend portainer. It has a recreate function that lets you recreate a container while pulling the latest image.

This is worked for me in iOS 7.

pageControl.pageIndicatorTintColor = [UIColor purpleColor];

Option 1

If you do not need to use Authentication you can add configs to ngrok commands

ngrok http 9000 --host-header=rewrite

or

ngrok http 9000 --host-header="localhost:9000"

But in this case Authentication will not work on your website because ngrok rewriting headers and session is not valid for your ngrok domain

Option 2

If you are using webpack you can add the following configuration

devServer: {
    disableHostCheck: true
}

In that case Authentication header will be valid for your ngrok domain

A sample code that works for me on Windows:

        for block in response.iter_content(1024):

            handle.write(block)

Math.sqrt returns a double so you'll have to cast it to int as well

distance = (int)Math.sqrt((x1-x2)*(x1-x2) + (y1-y2)*(y1-y2));

import re
pattern = re.compile("<(\d{4,5})>")

for i, line in enumerate(open('test.txt')):
    for match in re.finditer(pattern, line):
        print 'Found on line %s: %s' % (i+1, match.group())

A couple of notes about the regex:

• You don't need the ? at the end and the outer (...) if you don't want to match the number with the angle brackets, but only want the number itself
• It matches either 4 or 5 digits between the angle brackets

Update: It's important to understand that the match and capture in a regex can be quite different. The regex in my snippet above matches the pattern with angle brackets, but I ask to capture only the internal number, without the angle brackets.

More about regex in python can be found here : Regular Expression HOWTO

If someone used this:

val sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context)

PreferenceManager is now depricated, refactor to this:

val sharedPreferences = context.getSharedPreferences(context.packageName + "_preferences", Context.MODE_PRIVATE)

You can save it as .txt and change it manually using a mouse click and your keyboard. OR, when saving the file:

• choose All types(*.*) in the Save as type field.
• type filename.json in File name field

I suspect your string already actually only contains a single backslash, but you're looking at it in the debugger which is escaping it for you into a form which would be valid as a regular string literal in C#.

If print it out in the console, or in a message box, does it show with two backslashes or one?

If you actually want to replace a double backslash with a single one, it's easy to do so:

text = text.Replace(@"\\", @"\");

... but my guess is that the original doesn't contain a double backslash anyway. If this doesn't help, please give more details.

EDIT: In response to the edited question, your stringToBeReplaced only has a single backslash in. Really. Wherever you're seeing two backslashes, that viewer is escaping it. The string itself doesn't have two backslashes. Examine stringToBeReplaced.Length and count the characters.

Just for completion, here is a code example indicating the differences:

success \ error:

$http.get('/someURL')
.success(function(data, status, header, config) {
    // success handler
})
.error(function(data, status, header, config) {
    // error handler
});

then:

$http.get('/someURL')
.then(function(response) {
    // success handler
}, function(response) {
    // error handler
})
.then(function(response) {
    // success handler
}, function(response) {
    // error handler
})
.then(function(response) {
    // success handler
}, function(response) {
    // error handler
}).

Building on and updating a number of earlier responses (thanks: SilentGhost, nosklo, Ramkumar) a simple portable timer would use timeit's default_timer():

>>> import timeit
>>> tic=timeit.default_timer()
>>> # Do Stuff
>>> toc=timeit.default_timer()
>>> toc - tic #elapsed time in seconds

This will return the elapsed wall clock (real) time, not CPU time. And as described in the timeit documentation chooses the most precise available real-world timer depending on the platform.

ALso, beginning with Python 3.3 this same functionality is available with the time.perf_counter performance counter. Under 3.3+ timeit.default_timer() refers to this new counter.

For more precise/complex performance calculations, timeit includes more sophisticated calls for automatically timing small code snippets including averaging run time over a defined set of repetitions.

In an activity you can call recreate() to "recreate" the activity (API 11+)

$? is the exit status of a command, such that you can daisy-chain a series of commands.

Example

command1 && command2 && command3

command2 will run if command1's $? yields a success (0) and command3 will execute if $? of command2 will yield a success

Focus is for selecting UI components when you are using something besides touch (ie, a d-pad, a keyboard, etc.). Any view can receive focus, though some are not focusable by default. (You can make a view focusable with setFocusable(true) and force it to be focused with requestFocus().)

However, it is important to note that when you are in touch mode, focus is disabled. So if you are using your fingers, changing the focus programmatically doesn't do anything. The exception to this is for views that receive input from an input editor. An EditText is such an example. For this special situation setFocusableInTouchMode(true) is used to let the soft keyboard know where to send input. An EditText has this setting by default. The soft keyboard will automatically pop up.

If you don't want the soft keyboard popping up automatically then you can temporarily suppress it as @abeljus noted:

InputMethodManager inputManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);

When a user clicks on the EditText, it should still show the keyboard, though.

As you can see, the response is still HTTP/1.1 200 OK. To indicate a redirect, you need to send back a 302 status code:

response.setStatus(HttpServletResponse.SC_FOUND); // SC_FOUND = 302

(Swift 3)

Check if an element exists in an array (fulfilling some criteria), and if so, proceed working with the first such element

If the intent is:

1. To check whether an element exist in an array (/fulfils some boolean criteria, not necessarily equality testing),
2. And if so, proceed and work with the first such element,

Then an alternative to contains(_:) as blueprinted Sequence is to first(where:) of Sequence:

let elements = [1, 2, 3, 4, 5]

if let firstSuchElement = elements.first(where: { $0 == 4 }) {
    print(firstSuchElement) // 4
    // ...
}

In this contrived example, its usage might seem silly, but it's very useful if querying arrays of non-fundamental element types for existence of any elements fulfilling some condition. E.g.

struct Person {
    let age: Int
    let name: String
    init(_ age: Int, _ name: String) {
        self.age = age
        self.name = name
    }
}

let persons = [Person(17, "Fred"),   Person(16, "Susan"),
               Person(19, "Hannah"), Person(18, "Sarah"),
               Person(23, "Sam"),    Person(18, "Jane")]

if let eligableDriver = persons.first(where: { $0.age >= 18 }) {
    print("\(eligableDriver.name) can possibly drive the rental car in Sweden.")
    // ...
} // Hannah can possibly drive the rental car in Sweden.

let daniel = Person(18, "Daniel")
if let sameAgeAsDaniel = persons.first(where: { $0.age == daniel.age }) {
    print("\(sameAgeAsDaniel.name) is the same age as \(daniel.name).")
    // ...
} // Sarah is the same age as Daniel.

Any chained operations using .filter { ... some condition }.first can favourably be replaced with first(where:). The latter shows intent better, and have performance advantages over possible non-lazy appliances of .filter, as these will pass the full array prior to extracting the (possible) first element passing the filter.

Check if an element exists in an array (fulfilling some criteria), and if so, remove the first such element

A comment below queries:

How can I remove the firstSuchElement from the array?

A similar use case to the one above is to remove the first element that fulfils a given predicate. To do so, the index(where:) method of Collection (which is readily available to array collection) may be used to find the index of the first element fulfilling the predicate, whereafter the index can be used with the remove(at:) method of Array to (possible; given that it exists) remove that element.

var elements = ["a", "b", "c", "d", "e", "a", "b", "c"]

if let indexOfFirstSuchElement = elements.index(where: { $0 == "c" }) {
    elements.remove(at: indexOfFirstSuchElement)
    print(elements) // ["a", "b", "d", "e", "a", "b", "c"]
}

Or, if you'd like to remove the element from the array and work with, apply Optional:s map(_:) method to conditionally (for .some(...) return from index(where:)) use the result from index(where:) to remove and capture the removed element from the array (within an optional binding clause).

var elements = ["a", "b", "c", "d", "e", "a", "b", "c"]

if let firstSuchElement = elements.index(where: { $0 == "c" })
    .map({ elements.remove(at: $0) }) {

    // if we enter here, the first such element have now been
    // remove from the array
    print(elements) // ["a", "b", "d", "e", "a", "b", "c"]

    // and we may work with it
    print(firstSuchElement) // c
}

Note that in the contrived example above the array members are simple value types (String instances), so using a predicate to find a given member is somewhat over-kill, as we might simply test for equality using the simpler index(of:) method as shown in @DogCoffee's answer. If applying the find-and-remove approach above to the Person example, however, using index(where:) with a predicate is appropriate (since we no longer test for equality but for fulfilling a supplied predicate).

I do it like this:

(Shortened the code a bit)

public struct Age
{
    public readonly int Years;
    public readonly int Months;
    public readonly int Days;

}

public Age( int y, int m, int d ) : this()
{
    Years = y;
    Months = m;
    Days = d;
}

public static Age CalculateAge ( DateTime birthDate, DateTime anotherDate )
{
    if( startDate.Date > endDate.Date )
        {
            throw new ArgumentException ("startDate cannot be higher then endDate", "startDate");
        }

        int years = endDate.Year - startDate.Year;
        int months = 0;
        int days = 0;

        // Check if the last year, was a full year.
        if( endDate < startDate.AddYears (years) && years != 0 )
        {
            years--;
        }

        // Calculate the number of months.
        startDate = startDate.AddYears (years);

        if( startDate.Year == endDate.Year )
        {
            months = endDate.Month - startDate.Month;
        }
        else
        {
            months = ( 12 - startDate.Month ) + endDate.Month;
        }

        // Check if last month was a complete month.
        if( endDate < startDate.AddMonths (months) && months != 0 )
        {
            months--;
        }

        // Calculate the number of days.
        startDate = startDate.AddMonths (months);

        days = ( endDate - startDate ).Days;

        return new Age (years, months, days);
}

// Implement Equals, GetHashCode, etc... as well
// Overload equality and other operators, etc...

}

i came across a similar situation using booleans where I wanted to avoid calling b() if a was already false.

This worked for me:

a &= a && b()

If you want to print in the tabular form with, then you can use this:

echo "<tr> <td><h3> ".$cat['id']."</h3></td><td><h3> ".$cat['title']."<h3></</td><td> <h3>".$cat['desc']."</h3></td><td><h3> ".$cat['process']."%"."<a href='taskUpdate.php' >Update</a>"."</h3></td></tr>" ;

Another recursive approach:

# change directory to target folder:
cd /Volumes/path/to/folder

# find all things of type "f" (file), 
# then pipe "|" each result as an argument (xargs -0) 
# to the "xattr -c" command:
find . -type f -print0 | xargs -0 xattr -c

# Sometimes you may have to use a star * instead of the dot.
# The dot just means "here" (whereever your cd'd to
find * -type f -print0 | xargs -0 xattr -c

You need to do two things. First add the changes with

git add .
git stash  

git checkout <some branch>

It should solve your issue as it solved to me.

Try this it Only Run After Entire Page Has Loaded

By Javascript

window.onload = function(){
    // code goes here
};

By Jquery

$(window).bind("load", function() {
    // code goes here
});

Using just try_files didn't work for me - it caused a rewrite or internal redirection cycle error in my logs.

The Nginx docs had some additional details:

http://nginx.org/en/docs/http/ngx_http_core_module.html#try_files

So I ended up using the following:

root /var/www/mysite;

location / {
    try_files $uri /base.html;
}

location = /base.html {
    expires 30s;
}

(left, upper, right, lower) means two points,

1. (left, upper)
2. (right, lower)

with an 800x600 pixel image, the image's left upper point is (0, 0), the right lower point is (800, 600).

So, for cutting the image half:

from PIL import Image
img = Image.open("ImageName.jpg")

img_left_area = (0, 0, 400, 600)
img_right_area = (400, 0, 800, 600)

img_left = img.crop(img_left_area)
img_right = img.crop(img_right_area)

img_left.show()
img_right.show()

Coordinate System

The Python Imaging Library uses a Cartesian pixel coordinate system, with (0,0) in the upper left corner. Note that the coordinates refer to the implied pixel corners; the centre of a pixel addressed as (0, 0) actually lies at (0.5, 0.5).

Coordinates are usually passed to the library as 2-tuples (x, y). Rectangles are represented as 4-tuples, with the upper left corner given first. For example, a rectangle covering all of an 800x600 pixel image is written as (0, 0, 800, 600).

Here is an updated version of Paul Burke's answer. In versions below Android 4.4 (KitKat) we don't have the DocumentsContract class.

In order to work on versions below KitKat create this class:

public class DocumentsContract {
    private static final String DOCUMENT_URIS =
        "com.android.providers.media.documents " +
        "com.android.externalstorage.documents " +
        "com.android.providers.downloads.documents " +
        "com.android.providers.media.documents";

    private static final String PATH_DOCUMENT = "document";
    private static final String TAG = DocumentsContract.class.getSimpleName();

    public static String getDocumentId(Uri documentUri) {
        final List<String> paths = documentUri.getPathSegments();
        if (paths.size() < 2) {
            throw new IllegalArgumentException("Not a document: " + documentUri);
        }

        if (!PATH_DOCUMENT.equals(paths.get(0))) {
            throw new IllegalArgumentException("Not a document: " + documentUri);
        }
        return paths.get(1);
    }

    public static boolean isDocumentUri(Uri uri) {
        final List<String> paths = uri.getPathSegments();
        Logger.v(TAG, "paths[" + paths + "]");
        if (paths.size() < 2) {
            return false;
        }
        if (!PATH_DOCUMENT.equals(paths.get(0))) {
            return false;
        }
        return DOCUMENT_URIS.contains(uri.getAuthority());
    }
}

You can't return because you're not in a function. You can exit though.

import sys
sys.exit(0)

0 (the default) means success, non-zero means failure.

If 2 decimal places is your level of precision, then a "smallint" would handle this in the smallest space (2-bytes). You store the percent multiplied by 100.

EDIT: The decimal type is probably a better match. Then you don't need to manually scale. It takes 5 bytes per value.

| is a bitwise operator. || is a logical operator.

One will take two bits and or them.

One will determine truth (this OR that) If this is true or that is true, then the answer is true.

Oh, and dang people answer these questions fast.

Depends on what you mean by 'empty':

members[0] = '\0';

Add this to your client code :

ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(
    delegate
    {
        return true;
    });

Her is another R base approach:

From your example: Some date:

Some_date<-"01/01/1979"

We tell R, "That is a Date"

Some_date<-as.Date(Some_date)

We extract the month:

months(Some_date)

output: [1] "January"

Finally, we can convert it to a numerical variable:

as.numeric(as.factor(months(Some_date)))

outpt: [1] 1

xcopy "C:\SomeFolderName" "D:\SomeFolderName" /h /i /c /k /e /r /y

Use the above command. It will definitely work.

In this command data will be copied from c:\ to D:\, even folders and system files as well. Here's what the flags do:

• /h copies hidden and system files also
• /i if destination does not exist and copying more than one file, assume that destination must be a directory
• /c continue copying even if error occurs
• /k copies attributes
• /e copies directories and subdirectories, including empty ones
• /r overwrites read-only files
• /y suppress prompting to confirm whether you want to overwrite a file

This one worked for me

Private Sub TextBox1_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
        If KeyCode = 13 Then
             Button1_Click
        End If
End Sub

In curl request add time out 0 so its infinite time set like CURLOPT_TIMEOUT set 0

git clone git://github.com/ryanb/railscasts-episodes.git

The minimum ranges you can rely on are:

• short int and int: -32,767 to 32,767
• unsigned short int and unsigned int: 0 to 65,535
• long int: -2,147,483,647 to 2,147,483,647
• unsigned long int: 0 to 4,294,967,295

This means that no, long int cannot be relied upon to store any 10 digit number. However, a larger type long long int was introduced to C in C99 and C++ in C++11 (this type is also often supported as an extension by compilers built for older standards that did not include it). The minimum range for this type, if your compiler supports it, is:

• long long int: -9,223,372,036,854,775,807 to 9,223,372,036,854,775,807
• unsigned long long int: 0 to 18,446,744,073,709,551,615

So that type will be big enough (again, if you have it available).

A note for those who believe I've made a mistake with these lower bounds - I haven't. The C requirements for the ranges are written to allow for ones' complement or sign-magnitude integer representations, where the lowest representable value and the highest representable value differ only in sign. It is also allowed to have a two's complement representation where the value with sign bit 1 and all value bits 0 is a trap representation rather than a legal value. In other words, int is not required to be able to represent the value -32,768.

OOXML files like those that come from Excel 2007 are encoded in UTF-8, according to wikipedia. I don't know about CSV files, but it stands to reason it would use the same format...

Note also that "key" does not necessarily mean primary key. Something like this will work:

CREATE TABLE book (
    isbn             BIGINT NOT NULL PRIMARY KEY,
    id               INT    NOT NULL AUTO_INCREMENT,
    accepted_terms   BIT(1) NOT NULL,
    accepted_privacy BIT(1) NOT NULL,
    INDEX(id)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

This is a contrived example and probably not the best idea, but it can be very useful in certain cases.

If you set numberOfLines to 0 (and the label to word wrap), the label will automatically wrap and use as many of lines as needed.

If you're editing a UILabel in IB, you can enter multiple lines of text by pressing option+return to get a line break - return alone will finish editing.

Corrected a few things and added an alternative select - delete as appropriate.

here is how I did it in jquery:

jQuery.get('http://localhost/foo.txt', function(data) {
    alert(data);
});

Command-line flag

From man nano:

-T cols (--tabsize=cols)
    Set the size (width) of a tab to cols columns.
    The value of cols must be greater than 0. The default value is 8.
-E (--tabstospaces)
    Convert typed tabs to spaces.

For example, to set the tab size to 4, replace tabs with spaces, and edit the file "foo.txt", you would run the command:

nano -ET4 foo.txt

Config file

From man nanorc:

set tabsize n
    Use a tab size of n columns. The value of n must be greater than 0.
    The default value is 8.
set/unset tabstospaces
    Convert typed tabs to spaces.

Edit your ~/.nanorc file (create it if it does not exist), and add those commands to it. For example:

set tabsize 4
set tabstospaces

Nano will use these settings by default whenever it is launched, but command-line flags will override them.

Your problem stems from a misunderstanding of the or operator that is common to people learning programming languages like this. Yes, your immediate problem can be solved by writing x ~= 0 and x ~= 1, but I'll go into a little more detail about why your attempted solution doesn't work.

When you read x ~=(0 or 1) or x ~= 0 or 1 it's natural to parse this as you would the sentence "x is not equal to zero or one". In the ordinary understanding of that statement, "x" is the subject, "is not equal to" is the predicate or verb phrase, and "zero or one" is the object, a set of possibilities joined by a conjunction. You apply the subject with the verb to each item in the set.

However, Lua does not parse this based on the rules of English grammar, it parses it in binary comparisons of two elements based on its order of operations. Each operator has a precedence which determines the order in which it will be evaluated. or has a lower precedence than ~=, just as addition in mathematics has a lower precedence than multiplication. Everything has a lower precedence than parentheses.

As a result, when evaluating x ~=(0 or 1), the interpreter will first compute 0 or 1 (because of the parentheses) and then x ~= the result of the first computation, and in the second example, it will compute x ~= 0 and then apply the result of that computation to or 1.

The logical operator or "returns its first argument if this value is different from nil and false; otherwise, or returns its second argument". The relational operator ~= is the inverse of the equality operator ==; it returns true if its arguments are different types (x is a number, right?), and otherwise compares its arguments normally.

Using these rules, x ~=(0 or 1) will decompose to x ~= 0 (after applying the or operator) and this will return 'true' if x is anything other than 0, including 1, which is undesirable. The other form, x ~= 0 or 1 will first evaluate x ~= 0 (which may return true or false, depending on the value of x). Then, it will decompose to one of false or 1 or true or 1. In the first case, the statement will return 1, and in the second case, the statement will return true. Because control structures in Lua only consider nil and false to be false, and anything else to be true, this will always enter the if statement, which is not what you want either.

There is no way that you can use binary operators like those provided in programming languages to compare a single variable to a list of values. Instead, you need to compare the variable to each value one by one. There are a few ways to do this. The simplest way is to use De Morgan's laws to express the statement 'not one or zero' (which can't be evaluated with binary operators) as 'not one and not zero', which can trivially be written with binary operators:

if x ~= 1 and x ~= 0 then
    print( "X must be equal to 1 or 0" )
    return
end

Alternatively, you can use a loop to check these values:

local x_is_ok = false
for i = 0,1 do 
    if x == i then
        x_is_ok = true
    end
end
if not x_is_ok then
    print( "X must be equal to 1 or 0" )
    return
end

Finally, you could use relational operators to check a range and then test that x was an integer in the range (you don't want 0.5, right?)

if not (x >= 0 and x <= 1 and math.floor(x) == x) then
    print( "X must be equal to 1 or 0" )
    return
end

Note that I wrote x >= 0 and x <= 1. If you understood the above explanation, you should now be able to explain why I didn't write 0 <= x <= 1, and what this erroneous expression would return!

I would give a min-height and min-width to your overlay div of the size of the image, and change the background color on hover

.overlay { position: absolute; top: 0; left: 0;  z-index: 200; min-height:200px; min-width:200px; background-color: none;}
.overlay:hover { background-color: red;}

According to wikipedia article on status codes. Nginx has a custom error code when http traffic is sent to https port(error code 497)

And according to nginx docs on error_page, you can define a URI that will be shown for a specific error.
Thus we can create a uri that clients will be sent to when error code 497 is raised.

nginx.conf

#lets assume your IP address is 89.89.89.89 and also 
#that you want nginx to listen on port 7000 and your app is running on port 3000

server {
    listen 7000 ssl;
 
    ssl_certificate /path/to/ssl_certificate.cer;

However if a client makes a request via any other method except a GET, that request will be turned into a GET. Thus to preserve the request method that the client came in via; we use error processing redirects as shown in nginx docs on error_page

And thats why we use the 301 =307 redirect.

Using the nginx.conf file shown here, we are able to have http and https listen in on the same port

Syntax:

ALTER TABLE TABLE_NAME DROP COLUMN COLUMN_NAME;

For Example:

alter table Employee drop column address;

For just reading the last element of a slice:

sl[len(sl)-1]

For removing it:

sl = sl[:len(sl)-1]

I know this has been answered ages ago but I found the question while trying to incorporate an ssh login in a bash script and once logged in run a few commands and log back out and continue with the bash script. The simplest way I found which hasnt been mentioned elsewhere because it is so trivial is to do this.

#!/bin/bash

sshpass -p "password" ssh user@server 'cd /path/to/dir;somecommand;someothercommand;exit;'

You need to add a reference to System.Web.Extensions.dll in project for System.Web.Script.Serialization error.

This will work for tables and views (among other things) as well, not just sprocs:

SELECT
    '[' + s.name + '].[' + o.Name + ']',
    o.type_desc
FROM
    sys.objects o
    JOIN sys.schemas s ON s.schema_id = o.schema_id
WHERE
    o.name = 'CreateAllTheThings' -- if you are certain of the exact name
    OR o.name LIKE '%CreateAllThe%' -- if you are not so certain

It also gives you the schema name which will be useful in any non-trivial database (e.g. one where you need a query to find a stored procedure by name).

How to create an array of inputs with ng-model

Use the ng-repeat directive:

<ol>
  <li ng-repeat="n in [] | range:count">
    <input name="telephone-{{$index}}"
           ng-model="telephones[$index].value" >
  </li>
</ol>

The DEMO

angular.module("app",[])_x000D_
.controller("ctrl",function($scope){_x000D_
  $scope.count = 3;_x000D_
  $scope.telephones = [];_x000D_
})_x000D_
.filter("range",function() {_x000D_
  return (x,n) => Array.from({length:n},(x,index)=>(index));_x000D_
})

<script src="//unpkg.com/angular/angular.js"></script>_x000D_
<body ng-app="app" ng-controller="ctrl">_x000D_
    <button>_x000D_
      Array length_x000D_
      <input type="number" ng-model="count" _x000D_
             ng-change="telephones.length=count">_x000D_
    </button>_x000D_
    <ol>_x000D_
      <li ng-repeat="n in [] | range:count">_x000D_
        <input name="telephone-{{$index}}"_x000D_
               ng-model="telephones[$index].value" >_x000D_
      </li>_x000D_
    </ol>  _x000D_
    {{telephones}}_x000D_
</body>

The result is that this feature was considered for Java 7, but was not included.

Linux

To install different version of ruby, check the latest version of package using apt as below:

$ apt-cache madison ruby
      ruby |    1:1.9.3 | http://ftp.uk.debian.org/debian/ wheezy/main amd64 Packages
      ruby |        4.5 | http://ftp.uk.debian.org/debian/ squeeze/main amd64 Packages

Then install it:

$ sudo apt-get install ruby=1:1.9.3

To check what's the current version, run:

$ gem --version # Check for the current user.
$ sudo gem --version # Check globally.

If the version is still old, you may try to switch the version to new by using ruby version manager (rvm) by:

rvm 1.9.3

Note: You may prefix it by sudo if rvm was installed globally. Or run /usr/local/rvm/scripts/rvm if your command rvm is not in your global PATH. If rvm installation process failed, see the troubleshooting section.

Troubleshooting:

• If you still have the old version, you may try to install rvm (ruby version manager) via:

  sudo apt-get install curl # Install curl first
  curl -sSL https://get.rvm.io | bash -s stable --ruby # Install only for the user.
  #or:# curl -sSL https://get.rvm.io | sudo bash -s stable --ruby # Install globally. 
  

  then if installed locally (only for current user), load rvm via:

  source /usr/local/rvm/scripts/rvm; rvm 1.9.3
  

  if globally (for all users), then:

  sudo bash -c "source /usr/local/rvm/scripts/rvm; rvm 1.9.3"
  

• if you still having problem with the new ruby version, try to install it by rvm via:

  source /usr/local/rvm/scripts/rvm && rvm install ruby-1.9.3 # Locally.
  sudo bash -c "source /usr/local/rvm/scripts/rvm && rvm install ruby-1.9.3" # Globally.
  

• if you'd like to install some gems globally and you have rvm already installed, you may try:

  rvmsudo gem install [gemname]
  

  instead of:

    gem install [gemname] # or:
    sudo gem install [gemname]
  

Note: It's prefered to NOT use sudo to work with RVM gems. When you do sudo you are running commands as root, another user in another shell and hence all of the setup that RVM has done for you is ignored while the command runs under sudo (such things as GEM_HOME, etc...). So to reiterate, as soon as you 'sudo' you are running as the root system user which will clear out your environment as well as any files it creates are not able to be modified by your user and will result in strange things happening.

It's due to the fact that you have one long word without spaces. You can use the word-wrap property to cause the text to break:

#w74 { word-wrap: break-word; }

It has fairly good browser support, too. See documentation about it here.

In your onHandleSubmit function, set your state to {city: ''} again like this :

this.setState({ city: '' });

def merge(l1, l2, out=[]):
    if l1==[]: return out+l2
    if l2==[]: return out+l1
    if l1[0]<l2[0]: return merge(l1[1:], l2, out+l1[0:1])
    return merge(l1, l2[1:], out+l2[0:1])
def merge_sort(l): return (lambda h: l if h<1 else merge(merge_sort(l[:h]), merge_sort(l[h:])))(len(l)/2)
print(merge_sort([1,4,6,3,2,5,78,4,2,1,4,6,8]))

To get the first day of the month, simply get a Date and set the current day to day 1 of the month. Clear hour, minute, second and milliseconds if you need it.

private static Date firstDayOfMonth(Date date) {
   Calendar calendar = Calendar.getInstance();
   calendar.setTime(date);
   calendar.set(Calendar.DATE, 1);
   return calendar.getTime();
}

First day of the week is the same thing, but using Calendar.DAY_OF_WEEK instead

private static Date firstDayOfWeek(Date date) {
   Calendar calendar = Calendar.getInstance();
   calendar.setTime(date);
   calendar.set(Calendar.DAY_OF_WEEK, 1);
   return calendar.getTime();
}

If you don't have this ipython_notebook_config.py file, you can create one by following the readme and typing

ipython profile create

If you are fine using a graphical tool this works very well:

gitk <file>

gitk now shows all commits where the file has been updated. Marking a commit will show you the diff against the previous commit in the list. This also works for directories, but then you also get to select the file to diff for the selected commit. Super useful!

Compare the cell with "" (empty line):

=IF(A1="",1,0)

If all you are doing is replacing the existing data, then you can do this

std::vector<int> data; // evil global :)

void CopyData(int *newData, size_t count)
{
   data.assign(newData, newData + count);
}

The trick here is to use the -C (comment) parameter to specify your GCE userid. It looks like Google introduced this change last in 2018.

If the Google user who owns the GCE instance is [email protected] (which you will use as your login userid), then generate the key pair with (for example)

ssh-keygen -b521 -t ecdsa -C myname -f mykeypair

When you paste mykeypair.pub into the instance's public key list, you should see "myname" appear as the userid of the key.

Setting this up will let you use ssh, scp, etc from your command line.

I met the same problem, and I try the pdb.set_trace() before the error line.

My problem is the package name duplicate with the module name, like:

test
+-- __init__.py
+-- a
¦   +-- __init__.py
¦   +-- test.py
+-- b
    +-- __init__.py

and at file a/__init__.py, using from test.b import xxx will cause ImportError: No module named b.

The first check user logged in and then

if (Auth::check()){
    //get id of logged in user
    {{ Auth::getUser()->id}}

    //get the name of logged in user
    {{ Auth::getUser()->name }}
}

If you know the width is 400px this would be the easiest way to do it I guess.

 left: calc(50% - 200px);

First, reset any changes

This will undo any changes you've made to tracked files and restore deleted files:

git reset HEAD --hard

Second, remove new files

This will delete any new files that were added since the last commit:

git clean -fd

Files that are not tracked due to .gitignore are preserved; they will not be removed

Warning: using -x instead of -fd would delete ignored files. You probably don't want to do this.

This worked for me

On the Zipped folder of the ADT you initially downloaded unzip and navigate to:

adt-bundle-windows-x86_64-20140702\eclipse\plugins

Copy all the executable jar files and paste them on the

C:\adt-bundle-windows-x86_64-20140702\adt-bundle-windows-x86_64-20140702\eclipse\plugins

directory (or wherever your adt is located).
Any executable jar files missing in the plugin folder will be added. You should be able to launch eclipse

If you are able to use other associated technologies such as C#, I suggest using the built in SQL command with Transaction parameter.

var sqlCommand = new SqlCommand(commandText, null, transaction);

I've created a simple Console App that demonstrates this ability which can be found here: https://github.com/hecked12/SQL-Transaction-Using-C-Sharp

In short, C# allows you to overcome this limitation where you can inspect the output of each stored procedure and use that output however you like, for example you can feed it to another stored procedure. If the output is ok, you can commit the transaction, otherwise, you can revert the changes using rollback.

public class InShotApp extends Application {
    
        @Override
        public void onCreate() {
            super.onCreate();
            registerActivityLifecycle();
        }
    
        private void registerActivityLifecycle() {
    
            registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
                @Override
                public void onActivityCreated(@NonNull Activity activity, @Nullable Bundle savedInstanceState) {
                    activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE, WindowManager.LayoutParams.FLAG_SECURE);            }
    
                @Override
                public void onActivityStarted(@NonNull Activity activity) {
    
                }
    
                @Override
                public void onActivityResumed(@NonNull Activity activity) {
    
                }
    
                @Override
                public void onActivityPaused(@NonNull Activity activity) {
    
                }
    
                @Override
                public void onActivityStopped(@NonNull Activity activity) {
    
                }
    
                @Override
                public void onActivitySaveInstanceState(@NonNull Activity activity, @NonNull Bundle outState) {
    
                }
    
                @Override
                public void onActivityDestroyed(@NonNull Activity activity) {
    
                }
            });
    
        }
    }

There is no inherent limit. The maximum number of threads is determined by the amount of physical resources available. See this article by Raymond Chen for specifics.

If you need to ask what the maximum number of threads is, you are probably doing something wrong.

[Update: Just out of interest: .NET Thread Pool default numbers of threads:

• 1023 in Framework 4.0 (32-bit environment)
• 32767 in Framework 4.0 (64-bit environment)
• 250 per core in Framework 3.5
• 25 per core in Framework 2.0

(These numbers may vary depending upon the hardware and OS)]

This XML file does not appear to have any style information associated with it. The document tree is shown below.

You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml instead of text/html and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.

In case of JSF/Facelets files which have the default extension of .xhtml, that can in turn happen if the HTTP request hasn't invoked the FacesServlet and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml file extension which is in your Firefox configuration apparently by default interpreted as text/xml.

You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern> of the FacesServlet as registered in webapp's web.xml, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf, then you need to open the page by /some.jsf instead of /some.xhtml. Alternatively, you can also just change the <url-pattern> to *.xhtml. This way you never need to fiddle with virtual URLs.

See also:

• JSF Facelets: Sometimes I see the URL is .jsf and sometimes .xhtml. Why?

Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.

I think the best way to do this in 2020 is to use vanilla js and getBoundingClientRect().height;

Here's an example

let div = document.querySelector('div');
let divHeight = div.getBoundingClientRect().height;

console.log(`Div Height: ${divHeight}`);

<div>
  How high am I? 
</div>

On top of getting height this way, we also have access to a bunch of other stuff about the div.

let div = document.querySelector('div');
let divInfo = div.getBoundingClientRect();

console.log(divInfo);

<div>What else am I? </div>

if using /bin/sh you can use:

if [ <condition> ] && [ <condition> ]; then
    ...
fi

if using /bin/bash you can use:

if [[ <condition> && <condition> ]]; then
    ...
fi

Besides using one of the default formats you can specify any size you want in the unit you specify.

For example:

// Document of 210mm wide and 297mm high
new jsPDF('p', 'mm', [297, 210]);
// Document of 297mm wide and 210mm high
new jsPDF('l', 'mm', [297, 210]);
// Document of 5 inch width and 3 inch high
new jsPDF('l', 'in', [3, 5]);

The 3rd parameter of the constructor can take an array of the dimensions. However they do not correspond to width and height, instead they are long side and short side (or flipped around).

Your 1st parameter (landscape or portrait) determines what becomes the width and the height.

In the sourcecode on GitHub you can see the supported units (relative proportions to pt), and you can also see the default page formats (with their sizes in pt).

This works for searching files that contain both String1 and String2

(((.|\n)*)String1((.|\n)*)String2)|(((.|\n)*)String2((.|\n)*)String1)

Match any number of characters or line fields followed by String1 followed by any number of characters or line fields followed by String2 OR Match any number of characters or line fields followed by String2 followed by any number of characters or line fields followed by String1

This worked for me

document.getElementById('divElem').scrollIntoView();

It looks like you want the indices of the duplicates. Here is some short code that will find those in O(n) time, without using any packages:

dups = {}
[dups.setdefault(v, []).append(i) for i, v in enumerate(mylist)]
dups = {k: v for k, v in dups.items() if len(v) > 1}
# dups now has keys for all the duplicate values
# and a list of matching indices for each

# The second line produces an unused list. 
# It could be replaced with this:
for i, v in enumerate(mylist):
    dups.setdefault(v, []).append(i)

If the advice to add the closing braces work, I suggest adding indentation to your code so every closing brace is on a spaced separately, i.e.:

public class LuisRp3 {

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

    // stuff

    }
}

This just helps with readability.

If, on the other hand, you just forgot to copy the closing braces in your code, or the above suggestion doesn't work: open up the configuration and see if you can manually set the main class. I'm afraid I haven't used NetBeans much, so I can't help you with where that option is. My best guess is under "Run Configuration", or something like that.

Edit: See peeskillet's answer if adding closing braces doesn't work.

There's no point in declaring the class as static. Just declare its methods static and call them from the class name as normal, like Java's Math class.

Also, even though it isn't strictly necessary to make the constructor private, it is a good idea to do so. Marking the constructor private prevents other people from creating instances of your class, then calling static methods from those instances. (These calls work exactly the same in Java, they're just misleading and hurt the readability of your code.)

So, the trick here is to use absolute positioning calc like this:

top: calc(50% - XYpx);
left: calc(50% - XYpx);

where XYpx is half the size of your image, in my case, the image was a square. Of course, in this now obsolete case, the image must also change its size proportionally in response to window resize to be able to remain at the center without looking out of proportion.

All country codes are defined by the ITU. The following regex is based on ITU-T E.164 and Annex to ITU Operational Bulletin No. 930 – 15.IV.2009. It contains all current country codes and codes reserved for future use. While it could be shortened a bit, I decided to include each code independently.

This is for calls originating from the USA. For other countries, replace the international access code (the 011 at the beginning of the regex) with whatever is appropriate for that country's dialing plan.

Also, note that ITU E.164 defines the maximum length of a full international telephone number to 15 digits. This means a three digit country code results in up to 12 additional digits, and a 1 digit country code could contain up to 14 additional digits. Hence the

[0-9]{0,14}$

a the end of the regex.

Most importantly, this regex does not mean the number is valid - each country defines its own internal numbering plan. This only ensures that the country code is valid.

The way to access a session variable in Twig is:

{{ app.session.get('name_variable') }}

One difference is that:

• :map does nvo == normal + (visual + select) + operator pending
• :map! does ic == insert + command-line mode

as stated on help map-modes tables.

So: map does not map to all modes.

To map to all modes you need both :map and :map!.

Yes you will have to escape all double quotes by a backslash.

In Python 2.x, just use the ord and chr functions:

>>> ord('c')
99
>>> ord('c') + 1
100
>>> chr(ord('c') + 1)
'd'
>>> 

Python 3.x makes this more organized and interesting, due to its clear distinction between bytes and unicode. By default, a "string" is unicode, so the above works (ord receives Unicode chars and chr produces them).

But if you're interested in bytes (such as for processing some binary data stream), things are even simpler:

>>> bstr = bytes('abc', 'utf-8')
>>> bstr
b'abc'
>>> bstr[0]
97
>>> bytes([97, 98, 99])
b'abc'
>>> bytes([bstr[0] + 1, 98, 99])
b'bbc'

$("#elementName option").text(); 

This will give selected text of Combo-Box.

$("#elementName option").val();

This will give selected value associated selected item in Combo-Box.

$("#elementName option").length;

It will give the multi-select combobox values in the array and length will give number of element of the array.

You can achieve by running on terminal this:

curl -L -s 'https://registry.hub.docker.com/v2/repositories/library/mysql/tags/' | jq . | grep name

Also, if you don't have jq you have to install it by

sudo apt-get install jq

Okay, so I have just spent several hours looking for a viable method for posting multiple parameters to an MVC 4 WEB API, but most of what I found was either for a 'GET' action or just flat out did not work. However, I finally got this working and I thought I'd share my solution.

1. Use NuGet packages to download JSON-js json2 and Json.NET. Steps to install NuGet packages:

   (1) In Visual Studio, go to Website > Manage NuGet Packages...

   (2) Type json (or something to that effect) into the search bar and find JSON-js json2 and Json.NET. Double-clicking them will install the packages into the current project.

   (3) NuGet will automatically place the json file in ~/Scripts/json2.min.js in your project directory. Find the json2.min.js file and drag/drop it into the head of your website. Note: for instructions on installing .js (javascript) files, read this solution.

2. Create a class object containing the desired parameters. You will use this to access the parameters in the API controller. Example code:

   Public Class PostMessageObj
   
   Private _body As String
   Public Property body As String
       Get
           Return _body
       End Get
       Set(value As String)
           _body = value
       End Set
   End Property
   
   
   Private _id As String
   Public Property id As String
       Get
           Return _id
       End Get
       Set(value As String)
           _id = value
       End Set
   End Property
   End Class
   

3. Then we setup the actual MVC 4 Web API controller that we will be using for the POST action. In it, we will use Json.NET to deserialize the string object when it is posted. Remember to use the appropriate namespaces. Continuing with the previous example, here is my code:

   Public Sub PostMessage(<FromBody()> ByVal newmessage As String)
   
   Dim t As PostMessageObj = Newtonsoft.Json.JsonConvert.DeserializeObject(Of PostMessageObj)(newmessage)
   
   Dim body As String = t.body
   Dim i As String = t.id
   
   End Sub
   

4. Now that we have our API controller set up to receive our stringified JSON object, we can call the POST action freely from the client-side using $.ajax; Continuing with the previous example, here is my code (replace localhost+rootpath appropriately):

   var url = 'http://<localhost+rootpath>/api/Offers/PostMessage';
   var dataType = 'json'
   var data = 'nothn'
   var tempdata = { body: 'this is a new message...Ip sum lorem.',
       id: '1234'
   }
   var jsondata = JSON.stringify(tempdata)
   $.ajax({
       type: "POST",
       url: url,
       data: { '': jsondata},
       success: success(data),
       dataType: 'text'
   });
   

As you can see we are basically building the JSON object, converting it into a string, passing it as a single parameter, and then rebuilding it via the JSON.NET framework. I did not include a return value in our API controller so I just placed an arbitrary string value in the success() function.

Author's notes

This was done in Visual Studio 2010 using ASP.NET 4.0, WebForms, VB.NET, and MVC 4 Web API Controller. For anyone having trouble integrating MVC 4 Web API with VS2010, you can download the patch to make it possible. You can download it from Microsoft's Download Center.

Here are some additional references which helped (mostly in C#):

• Using jQuery to Post FromBody Parameters
• Sending JSON object to Web API
• And of course J Torres's answer was the last piece of the puzzle.

In order to overcome

Ambiguous output in step `CR-LF..data'

simply solution might be to add -f flag to force conversion.

The read_excel() function has a converters argument, where you can apply functions to input in certain columns. You can use this to keep them as strings. Documentation:

Dict of functions for converting values in certain columns. Keys can either be integers or column labels, values are functions that take one input argument, the Excel cell content, and return the transformed content.

Example code:

pandas.read_excel(my_file, converters = {my_str_column: str})

Make sure the client computer has the same or higher version of the .NET framework that you built your program to.

No functions, no cursors. Try this

with cte as(
select CHAR(65) chr, 65 i 
union all
select CHAR(i+1) chr, i=i+1 from cte
where CHAR(i) <'Z'
)
select * from(
SELECT id, Case when LEN(data)>len(REPLACE(data, chr,'')) then chr+chr end data 
FROM table1, cte) x
where Data is not null

Try this:

    private void comboBox1_KeyDown(object sender, KeyEventArgs e)
    {
        // comboBox1 is readonly
        e.SuppressKeyPress = true;
    }

Try this:

let vc = ViewController() //change this to your class name
self.presentViewController(vc, animated: true, completion: nil)

With Swift3:

self.present(vc, animated: true, completion: nil)

You can do it like this and you mod function will work perfect let me know if you want a code pen

  <div ng-repeat="icon in icons">                   
                <div class="row" ng-if="$index % 3 == 0 ">
                    <i class="col col-33 {{icons[$index + n].icon}} custom-icon"></i>
                    <i class="col col-33 {{icons[$index + n + 1].icon}} custom-icon"></i>
                    <i class="col col-33 {{icons[$index + n + 2].icon}} custom-icon"></i>
                </div>
         </div>

In the context of constraint animation, I would like to mention a specific situation where I animated a constraint immediately within a keyboard_opened notification.

Constraint defined a top space from a textfield to top of the container. Upon keyboard opening, I just divide the constant by 2.

I was unable to achieve a conistent smooth constraint animation directly within the keyboard notification. About half the times view would just jump to its new position - without animating.

It occured to me there might be some additional layouting happening as result of keyboard opening. Adding a simple dispatch_after block with a 10ms delay made the animation run every time - no jumping.

When you do a cmp a,b, the flags are set as if you had calculated a - b.

Then the jmp-type instructions check those flags to see if the jump should be made.

In other words, the first block of code you have (with my comments added):

cmp al,dl     ; set flags based on the comparison
jg label1     ; then jump based on the flags

would jump to label1 if and only if al was greater than dl.

You're probably better off thinking of it as al > dl but the two choices you have there are mathematically equivalent:

al > dl
al - dl > dl - dl (subtract dl from both sides)
al - dl > 0       (cancel the terms on the right hand side)

You need to be careful when using jg inasmuch as it assumes your values were signed. So, if you compare the bytes 101 (101 in two's complement) with 200 (-56 in two's complement), the former will actually be greater. If that's not what was desired, you should use the equivalent unsigned comparison.

See here for more detail on jump selection, reproduced below for completeness. First the ones where signed-ness is not appropriate:
