If you are sure your JSON is safely under your control (not user input) then you can simply evaluate the JSON. Eval accepts all quote types as well as unquoted property names.

var str = "{'a':1}";
var myObject = (0, eval)('(' + str + ')');

The extra parentheses are required due to how the eval parser works. Eval is not evil when it is used on data you have control over. For more on the difference between JSON.parse and eval() see JSON.parse vs. eval()

The problem is that when redirecting a file into 'mail' like that, it's used for the message body only. Any headers you embed in the file will go into the body instead.

Try:

mail --append="Content-type: text/html" -s "Built notification" [email protected] < /var/www/report.csv

--append lets you add arbitrary headers to the mail, which is where you should specify the content-type and content-disposition. There's no need to embed the To and Subject headers in your file, or specify them with --append, since you're implicitly setting them on the command line already (-s is the subject, and [email protected] automatically becomes the To).

More recent pandas versions have the pd.DataFrame.multiply function.

df['quantity'] = df['quantity'].multiply(-1)

Variables can contain single quotes.

myvar=\'....$variable\'

repo forall -c $myvar

Are you getting errors, or just not sure where to start?

%pylab inline

I want to do a for loop, yet with askewchan's method it does not work well, so I have modified it.

x = np.empty((0,3))
y = np.array([1,2,3])
for i in ...
    x = np.vstack((x,y))

Beware of circular references when DOM objects are involved:

Memory leak patterns in JavaScript

Keep in mind that memory can only be reclaimed when there are no active references to the object. This is a common pitfall with closures and event handlers, as some JS engines will not check which variables actually are referenced in inner functions and just keep all local variables of the enclosing functions.

Here's a simple example:

function init() {
    var bigString = new Array(1000).join('xxx');
    var foo = document.getElementById('foo');
    foo.onclick = function() {
        // this might create a closure over `bigString`,
        // even if `bigString` isn't referenced anywhere!
    };
}

A naive JS implementation can't collect bigString as long as the event handler is around. There are several ways to solve this problem, eg setting bigString = null at the end of init() (delete won't work for local variables and function arguments: delete removes properties from objects, and the variable object is inaccessible - ES5 in strict mode will even throw a ReferenceError if you try to delete a local variable!).

I recommend to avoid unnecessary closures as much as possible if you care for memory consumption.

How about:

class MyClass(object):
    def __init__(self, filename):
        self.filename = filename 
        self.stats = parse_file(filename)

def parse_file(filename):
    #do some parsing
    return results_from_parse

By the way, if you have variables named stat1, stat2, etc., the situation is begging for a tuple: stats = (...).

So let parse_file return a tuple, and store the tuple in self.stats.

Then, for example, you can access what used to be called stat3 with self.stats[2].

There is a difference between them,
continue skips the loop's current iteration and executes the next iteration.
pass does nothing. It’s an empty statement placeholder.
I would rather give you an example, which will clarify this more better.

>>> for element in some_list:
...     if element == 1:
...         print "Pass executed"
...         pass
...     print element
... 
0
Pass executed
1
2

>>> for element in some_list:
...     if element == 1:
...         print "Continue executed"
...         continue
...     print element
... 
0
Continue executed
2

You could use remove(). More information on jQuery remove().

$(this).children("ul").remove();

Note that this will remove all ul elements that are children.

ZShape is not static so it requires an instance of the outer class.

The simplest solution is to make ZShape and any nested class static if you can.

I would also make any fields final or static final that you can as well.

This is a really simple method using splice

Array.prototype.moveToStart = function(index) {
    this.splice(0, 0, this.splice(index, 1)[0]);
    return this;
  };

try something like this:

if (_id_categoria_padre > 0)
{
    objComando.Parameters.Add("id_categoria_padre", SqlDbType.Int).Value = _id_categoria_padre;
}
else
{
    objComando.Parameters.Add("id_categoria_padre", DBNull.Value).Value = DBNull.Value;
}

For the 24-hour time, you need to use HH24 instead of HH.

For the 12-hour time, the AM/PM indicator is written as A.M. (if you want periods in the result) or AM (if you don't). For example:

SELECT invoice_date,
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"
  FROM invoices
;

For more information on the format models you can use with TO_CHAR on a date, see http://docs.oracle.com/cd/E16655_01/server.121/e17750/ch4datetime.htm#NLSPG004.

If you're using Python 3, just execute python3 get-pip.py . It is just a simple command.

How about using java.util.Arrays?

List<String> list = Arrays.asList((String[])jsonArray.toArray())

I use macros based on Ron's solution.

#define TICK(XXX) NSDate *XXX = [NSDate date]
#define TOCK(XXX) NSLog(@"%s: %f", #XXX, -[XXX timeIntervalSinceNow])

For lines of code:

TICK(TIME1);
/// do job here
TOCK(TIME1);

we'll see in console something like: TIME1: 0.096618

In Content page you can access the label and set the text such as

Here 'lblStatus' is the your master page label ID

Label lblMasterStatus = (Label)Master.FindControl("lblStatus");

lblMasterStatus.Text  = "Meaasage from content page";

For me everything else was almost ok, but somehow my project settings changed & iisExpress was getting used instead of IISLocal. When I changed & pointed to the virtual directory (in IISLocal), it stared working perfectly again.

Using $ docker inspect Incase the Image has no /bin/bash in the output, you can use command below: it worked for me perfectly

$ docker exec -it <container id> sh

I'm taking a cue from the comments in @Dhara's answer, it sounds like you want to set a list of new_tick_locations by a function from the old x-axis to the new x-axis. The tick_function below takes in a numpy array of points, maps them to a new value and formats them:

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax1 = fig.add_subplot(111)
ax2 = ax1.twiny()

X = np.linspace(0,1,1000)
Y = np.cos(X*20)

ax1.plot(X,Y)
ax1.set_xlabel(r"Original x-axis: $X$")

new_tick_locations = np.array([.2, .5, .9])

def tick_function(X):
    V = 1/(1+X)
    return ["%.3f" % z for z in V]

ax2.set_xlim(ax1.get_xlim())
ax2.set_xticks(new_tick_locations)
ax2.set_xticklabels(tick_function(new_tick_locations))
ax2.set_xlabel(r"Modified x-axis: $1/(1+X)$")
plt.show()

ucfagls is right, providing you use the plot() command. If not, please give us more detail.

In any case, you can control every axis seperately by using the axis() command and the xaxt/yaxt options in plot(). Using the data of ucfagls, this becomes :

plot(Y ~ X, data=foo,yaxt="n")
axis(2,cex.axis=2)

the option yaxt="n" is necessary to avoid that the plot command plots the y-axis without changing. For the x-axis, this works exactly the same :

plot(Y ~ X, data=foo,xaxt="n")
axis(1,cex.axis=2)

See also the help files ?par and ?axis

Edit : as it is for a barplot, look at the options cex.axis and cex.names :

tN <- table(sample(letters[1:5],100,replace=T,p=c(0.2,0.1,0.3,0.2,0.2)))

op <- par(mfrow=c(1,2))
barplot(tN, col=rainbow(5),cex.axis=0.5) # for the Y-axis
barplot(tN, col=rainbow(5),cex.names=0.5) # for the X-axis
par(op)

Actually, all of those examples on the web wherein the common content/file type like "js", "css", "img", etc is been used as library name are misleading.

Real world examples

To start, let's look at how existing JSF implementations like Mojarra and MyFaces and JSF component libraries like PrimeFaces and OmniFaces use it. No one of them use resource libraries this way. They use it (under the covers, by @ResourceDependency or UIViewRoot#addComponentResource()) the following way:

<h:outputScript library="javax.faces" name="jsf.js" />
<h:outputScript library="primefaces" name="jquery/jquery.js" />
<h:outputScript library="omnifaces" name="omnifaces.js" />
<h:outputScript library="omnifaces" name="fixviewstate.js" />
<h:outputScript library="omnifaces.combined" name="[dynamicname].js" />
<h:outputStylesheet library="primefaces" name="primefaces.css" />
<h:outputStylesheet library="primefaces-aristo" name="theme.css" />
<h:outputStylesheet library="primefaces-vader" name="theme.css" />

It should become clear that it basically represents the common library/module/theme name where all of those resources commonly belong to.

Easier identifying

This way it's so much easier to specify and distinguish where those resources belong to and/or are coming from. Imagine that you happen to have a primefaces.css resource in your own webapp wherein you're overriding/finetuning some default CSS of PrimeFaces; if PrimeFaces didn't use a library name for its own primefaces.css, then the PrimeFaces own one wouldn't be loaded, but instead the webapp-supplied one, which would break the look'n'feel.

Also, when you're using a custom ResourceHandler, you can also apply more finer grained control over resources coming from a specific library when library is used the right way. If all component libraries would have used "js" for all their JS files, how would the ResourceHandler ever distinguish if it's coming from a specific component library? Examples are OmniFaces CombinedResourceHandler and GraphicResourceHandler; check the createResource() method wherein the library is checked before delegating to next resource handler in chain. This way they know when to create CombinedResource or GraphicResource for the purpose.

Noted should be that RichFaces did it wrong. It didn't use any library at all and homebrewed another resource handling layer over it and it's therefore impossible to programmatically identify RichFaces resources. That's exactly the reason why OmniFaces CombinedResourceHander had to introduce a reflection-based hack in order to get it to work anyway with RichFaces resources.

Your own webapp

Your own webapp does not necessarily need a resource library. You'd best just omit it.

<h:outputStylesheet name="css/style.css" />
<h:outputScript name="js/script.js" />
<h:graphicImage name="img/logo.png" />

Or, if you really need to have one, you can just give it a more sensible common name, like "default" or some company name.

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

Or, when the resources are specific to some master Facelets template, you could also give it the name of the template, so that it's easier to relate each other. In other words, it's more for self-documentary purposes. E.g. in a /WEB-INF/templates/layout.xhtml template file:

<h:outputStylesheet library="layout" name="css/style.css" />
<h:outputScript library="layout" name="js/script.js" />

And a /WEB-INF/templates/admin.xhtml template file:

<h:outputStylesheet library="admin" name="css/style.css" />
<h:outputScript library="admin" name="js/script.js" />

For a real world example, check the OmniFaces showcase source code.

Or, when you'd like to share the same resources over multiple webapps and have created a "common" project for that based on the same example as in this answer which is in turn embedded as JAR in webapp's /WEB-INF/lib, then also reference it as library (name is free to your choice; component libraries like OmniFaces and PrimeFaces also work that way):

<h:outputStylesheet library="common" name="css/style.css" />
<h:outputScript library="common" name="js/script.js" />
<h:graphicImage library="common" name="img/logo.png" />

Library versioning

Another main advantage is that you can apply resource library versioning the right way on resources provided by your own webapp (this doesn't work for resources embedded in a JAR). You can create a direct child subfolder in the library folder with a name in the \d+(_\d+)* pattern to denote the resource library version.

WebContent
 |-- resources
 |    `-- default
 |         `-- 1_0
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

When using this markup:

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

This will generate the following HTML with the library version as v parameter:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_0" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_0"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_0" alt="" />

So, if you have edited/updated some resource, then all you need to do is to copy or rename the version folder into a new value. If you have multiple version folders, then the JSF ResourceHandler will automatically serve the resource from the highest version number, according to numerical ordering rules.

So, when copying/renaming resources/default/1_0/* folder into resources/default/1_1/* like follows:

WebContent
 |-- resources
 |    `-- default
 |         |-- 1_0
 |         |    :
 |         |
 |         `-- 1_1
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

Then the last markup example would generate the following HTML:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_1" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_1"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_1" alt="" />

This will force the webbrowser to request the resource straight from the server instead of showing the one with the same name from the cache, when the URL with the changed parameter is been requested for the first time. This way the endusers aren't required to do a hard refresh (Ctrl+F5 and so on) when they need to retrieve the updated CSS/JS resource.

Please note that library versioning is not possible for resources enclosed in a JAR file. You'd need a custom ResourceHandler. See also How to use JSF versioning for resources in jar.

In the detached 'Tool Options' window, click on the red 'X' in the upper right corner to get rid of the window. Then on the main Gimp screen, click on 'Windows,' then 'Dockable Dialogs.' The first entry on its list will be 'Tool Options,' so click on that. Then, Tool Options will appear as a tab in the window on the right side of the screen, along with layers and undo history. Click and drag that tab over to the toolbox window on hte left and drop it inside. The tool options will again be docked in the toolbox.

you define the struct as xyx but you're trying to create the struct called xyz.

I was also missing proxy in above answer. I used get_ip_address_from_request from django_easy_timezones.

from easy_timezones.utils import get_ip_address_from_request, is_valid_ip, is_local_ip
ip = get_ip_address_from_request(request)
try:
    if is_valid_ip(ip):
        geoip_record = IpRange.objects.by_ip(ip)
except IpRange.DoesNotExist:
    return None

And here is method get_ip_address_from_request, IPv4 and IPv6 ready:

def get_ip_address_from_request(request):
    """ Makes the best attempt to get the client's real IP or return the loopback """
    PRIVATE_IPS_PREFIX = ('10.', '172.', '192.', '127.')
    ip_address = ''
    x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR', '')
    if x_forwarded_for and ',' not in x_forwarded_for:
        if not x_forwarded_for.startswith(PRIVATE_IPS_PREFIX) and is_valid_ip(x_forwarded_for):
            ip_address = x_forwarded_for.strip()
    else:
        ips = [ip.strip() for ip in x_forwarded_for.split(',')]
        for ip in ips:
            if ip.startswith(PRIVATE_IPS_PREFIX):
                continue
            elif not is_valid_ip(ip):
                continue
            else:
                ip_address = ip
                break
    if not ip_address:
        x_real_ip = request.META.get('HTTP_X_REAL_IP', '')
        if x_real_ip:
            if not x_real_ip.startswith(PRIVATE_IPS_PREFIX) and is_valid_ip(x_real_ip):
                ip_address = x_real_ip.strip()
    if not ip_address:
        remote_addr = request.META.get('REMOTE_ADDR', '')
        if remote_addr:
            if not remote_addr.startswith(PRIVATE_IPS_PREFIX) and is_valid_ip(remote_addr):
                ip_address = remote_addr.strip()
    if not ip_address:
        ip_address = '127.0.0.1'
    return ip_address

Since DateTime is a value type you cannot assign null to it, but exactly for these cases (absence of a value) Nullable<T> was introduced - use a nullable DateTime instead:

DateTime? myTime = null;

Just a side note for similar problem (If we don't want to loop through):

How to lookup a dictionary using a variable key within Jinja template?

Here is an example:

{% set key = target_db.Schema.upper()+"__"+target_db.TableName.upper() %}
{{ dict_containing_df.get(key).to_html() | safe }}

It might be obvious. But we don't need curly braces within curly braces. Straight python syntax works. (I am posting because I was confusing to me...)

Alternatively, you can simply do

{{dict[target_db.Schema.upper()+"__"+target_db.TableName.upper()]).to_html() | safe }}

But it will spit an error when no key is found. So better to use get in Jinja.

I think this question has a contextual component.

If you're simply pulling data from a service & radiating that information to it's view, I think binding directly to the service property is just fine. I don't want to write a lot of boilerplate code to simply map service properties to model properties to consume in my view.

Further, performance in angular is based on two things. The first is how many bindings are on a page. The second is how expensive getter functions are. Misko talks about this here

If you need to perform instance specific logic on the service data (as opposed to data massaging applied within the service itself), and the outcome of this impacts the data model exposed to the view, then I would say a $watcher is appropriate, as long as the function isn't terribly expensive. In the case of an expensive function, I would suggest caching the results in a local (to controller) variable, performing your complex operations outside of the $watcher function, and then binding your scope to the result of that.

As a caveat, you shouldn't be hanging any properties directly off your $scope. The $scope variable is NOT your model. It has references to your model.

In my mind, "best practice" for simply radiating information from service down to view:

function TimerCtrl1($scope, Timer) {
  $scope.model = {timerData: Timer.data};
};

And then your view would contain {{model.timerData.lastupdated}}.

To get just the value (without attribute names), use string():

string(//Parent[@id='1']/Children/child/@name)

The fn:string() fucntion will return the value of its argument as xs:string. In case its argument is an attribute, it will therefore return the attribute's value as xs:string.

You can use this as well

import numpy as np
x=np.array(['1.1', '2.2', '3.3'])
x=np.asfarray(x,float)

You have referenced the jQuery JS file haven't you? There's no reason why farzad's answer shouldn't work.

I'm using out of the box MVC4 with this code (note the two parameters inside ToDictionary)

 var result = new JsonResult()
 {
     Data = new
     {
         partials = GetPartials(data.Partials).ToDictionary(x => x.Key, y=> y.Value)
     }
 };

I get what's expected:

{"partials":{"cartSummary":"\u003cb\u003eCART SUMMARY\u003c/b\u003e"}}

Important: WebAPI in MVC4 uses JSON.NET serialization out of the box, but the standard web JsonResult action result doesn't. Therefore I recommend using a custom ActionResult to force JSON.NET serialization. You can also get nice formatting

Here's a simple actionresult JsonNetResult

http://james.newtonking.com/archive/2008/10/16/asp-net-mvc-and-json-net.aspx

You'll see the difference (and can make sure you're using the right one) when serializing a date:

Microsoft way:

 {"wireTime":"\/Date(1355627201572)\/"}

JSON.NET way:

 {"wireTime":"2012-12-15T19:07:03.5247384-08:00"}

You forgot to add self as a parameter to the function worker() in the class KeyStatisticCollection.

While it is straightforward to find if their is a subset or not that sums to the target, implementation gets tricky when you need to keep track of the partial subsets under consideration.

If you use a linked list, a hash set or any another generic collection, you would be tempted to add an item to this collection before the call that includes the item, and then remove it before the call that excludes the item. This does not work as expected, as the stack frames in which the add will occur is not the same as the one in which remove will occur.

Solution is to use a string to keep track of the sequence. Appends to the string can be done inline in the function call; thereby maintaining the same stack frame and your answer would then conform beautifully to the original hasSubSetSum recursive structure.

import java.util.ArrayList;

public class Solution {

public static boolean hasSubSet(int [] A, int target) {
    ArrayList<String> subsets = new ArrayList<>();
    helper(A, target, 0, 0, subsets, "");
    // Printing the contents of subsets is straightforward
    return !subsets.isEmpty();
}

private static void helper(int[] A, int target, int sumSoFar, int i, ArrayList<String> subsets, String curr) {
    if(i == A.length) {
        if(sumSoFar == target) {
            subsets.add(curr);
        }
        return;
    }
    helper(A, target, sumSoFar, i+1, subsets, curr);
    helper(A, target, sumSoFar + A[i], i+1, subsets, curr + A[i]);
}

public static void main(String [] args) {
    System.out.println(hasSubSet(new int[] {1,2,4,5,6}, 8));
}

}

The above answers may help you but you may also want to know how to use array of function pointers.

void fun1()
{

}

void fun2()
{

}

void fun3()
{

}

void (*func_ptr[3])() = {fun1, fun2, fun3};

main()
{
    int option;


    printf("\nEnter function number you want");
    printf("\nYou should not enter other than 0 , 1, 2"); /* because we have only 3 functions */
    scanf("%d",&option);

    if((option>=0)&&(option<=2))
    { 
        (*func_ptr[option])();
    }

    return 0;
}

You can only assign the addresses of functions with the same return type and same argument types and no of arguments to a single function pointer array.

You can also pass arguments like below if all the above functions are having the same number of arguments of same type.

  (*func_ptr[option])(argu1);

Note: here in the array the numbering of the function pointers will be starting from 0 same as in general arrays. So in above example fun1 can be called if option=0, fun2 can be called if option=1 and fun3 can be called if option=2.

You can use the Gson library for parsing

void getJson() throws IOException {
    HttpClient  httpClient = new DefaultHttpClient();
    HttpGet httpGet = new HttpGet("some url of json");
    HttpResponse httpResponse = httpClient.execute(httpGet);
    String response = EntityUtils.toString(httpResponse.getEntity());

    Gson gson = new Gson();
    MyClass myClassObj = gson.fromJson(response, MyClass.class);

}

here is sample json file which is fetchd from server

{
"id":5,
"name":"kitkat",
"version":"4.4"
}

here is my class

class MyClass{
int id;
String name;
String version;
}

refer this

$array = explode(' ', $string);

There is an animationend Event that can be observed see documentation here, also for css transition animations you could use the transitionend event

There is no need for additional libraries these all work with vanilla JS

document.getElementById("myDIV").addEventListener("transitionend", myEndFunction);_x000D_
function myEndFunction() {_x000D_
 this.innerHTML = "transition event ended";_x000D_
}

#myDIV {transition: top 2s; position: relative; top: 0;}_x000D_
div {background: #ede;cursor: pointer;padding: 20px;}

<div id="myDIV" onclick="this.style.top = '55px';">Click me to start animation.</div>

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

Not a direct answer to OP's problem, but it may help you too. You can declare a local variable next to some html inside a scope without trouble.

@foreach (var item in Model.Stuff)
{
    var file = item.MoreStuff.FirstOrDefault();

    <li><a href="@item.Source">@file.Name</a></li>
}

That is because you are trying to access the plugin before it's loaded. You should try making a call to it when the DOM is loaded by surrounding it with this:

$(document).ready(function(){
    $("#colorpicker").colorpicker();
}

protocol must be subClass of AnyObject, class

example given below

    protocol NameOfProtocol: class {
   // member of protocol
    }
   class ClassName: UIViewController {
      weak var delegate: NameOfProtocol? 
    }

• getattr(x, 'y') is equivalent to x.y
• setattr(x, 'y', v) is equivalent to x.y = v
• delattr(x, 'y') is equivalent to del x.y

There is no single function that does what you want. Your definition of shift is slightly different than what most people are doing. The ways to shift an array are more commonly looped:

>>>xs=np.array([1,2,3,4,5])
>>>shift(xs,3)
array([3,4,5,1,2])

However, you can do what you want with two functions.
Consider a=np.array([ 0., 1., 2., 3., 4., 5., 6., 7., 8., 9.]):

def shift2(arr,num):
    arr=np.roll(arr,num)
    if num<0:
         np.put(arr,range(len(arr)+num,len(arr)),np.nan)
    elif num > 0:
         np.put(arr,range(num),np.nan)
    return arr
>>>shift2(a,3)
[ nan  nan  nan   0.   1.   2.   3.   4.   5.   6.]
>>>shift2(a,-3)
[  3.   4.   5.   6.   7.   8.   9.  nan  nan  nan]

After running cProfile on your given function and the above code you provided, I found that the code you provided makes 42 function calls while shift2 made 14 calls when arr is positive and 16 when it is negative. I will be experimenting with timing to see how each performs with real data.

I think you've answered your own question: try not to go beyond the 70 Mb limit, however it really depends on many things: what iOS version you're using (not SDK), how many applications running in background, what exact memory you're using etc.

Just avoid the instant memory splashes (e.g. you're using 40 Mb of RAM, and then allocating 80 Mb's more for some short computation). In this case iOS would kill your application immediately.

You should also consider lazy loading of assets (load them only when you really need and not beforehand).

Here is a full example of an axios.post request with custom headers

var postData = {_x000D_
  email: "[email protected]",_x000D_
  password: "password"_x000D_
};_x000D_
_x000D_
let axiosConfig = {_x000D_
  headers: {_x000D_
      'Content-Type': 'application/json;charset=UTF-8',_x000D_
      "Access-Control-Allow-Origin": "*",_x000D_
  }_x000D_
};_x000D_
_x000D_
axios.post('http://<host>:<port>/<path>', postData, axiosConfig)_x000D_
.then((res) => {_x000D_
  console.log("RESPONSE RECEIVED: ", res);_x000D_
})_x000D_
.catch((err) => {_x000D_
  console.log("AXIOS ERROR: ", err);_x000D_
})

This may seem a bit lengthy, but it worked for me without any error.

At first, Install phppgadmin from Ubuntu Software Center.

Then run these steps in terminal.

sudo apt-get install libpq-dev python-dev
pip install psycopg2
sudo apt-get install postgresql postgresql-contrib phppgadmin

Start the apache server

sudo service apache2 start

Now run this too in terminal, to edit the apache file.

sudo gedit /etc/apache2/apache2.conf

Add the following line to the opened file:

Include /etc/apache2/conf.d/phppgadmin

Now reload apache. Use terminal.

sudo /etc/init.d/apache2 reload

Now you will have to create a new database. Login as 'postgres' user. Continue in terminal.

sudo su - postgres

In case you have trouble with the password of 'postgres', you can change it using the answer here https://stackoverflow.com/a/12721020/1990793 and continue with the steps.

Now create a database

createdb <db_name>

Now create a new user to login to phppgadmin later, providing a new password.

createuser -P <new_user>

Now your postgressql has been setup, and you can go to:

http://localhost/phppgadmin/

and login using the new user you've created, in order to view the database.

Yes, it is possible:

git clone https://github.com/pitosalas/st3_packages Packages 

You can specify the local root directory when using git clone.

<directory> 

The name of a new directory to clone into.
The "humanish" part of the source repository is used if no directory is explicitly given (repo for /path/to/repo.git and foo for host.xz:foo/.git).
Cloning into an existing directory is only allowed if the directory is empty.

As Chris comments, you can then rename that top directory.
Git only cares about the .git within said top folder, which you can get with various commands:

git rev-parse --show-toplevel git rev-parse --git-dir 

You can get the url like this:

Request.Headers["Referer"]

Explanation

The Request.UrlReferer will throw a System.UriFormatException if the referer HTTP header is malformed (which can happen since it is not usually under your control).

As for using Request.ServerVariables, per MSDN:

Request.ServerVariables Collection

The ServerVariables collection retrieves the values of predetermined environment variables and request header information.

Request.Headers Property

Gets a collection of HTTP headers.

I guess I don't understand why you would prefer the Request.ServerVariables over Request.Headers, since Request.ServerVariables contains all of the environment variables as well as the headers, where Request.Headers is a much shorter list that only contains the headers.

So the best solution is to use the Request.Headers collection to read the value directly. Do heed Microsoft's warnings about HTML encoding the value if you are going to display it on a form, though.

Here's an efficient option that doesn't use the clipboard.

Sub transposeAndPasteRow(rowToCopy As Range, pasteTarget As Range)
    pasteTarget.Resize(rowToCopy.Columns.Count) = Application.WorksheetFunction.Transpose(rowToCopy.Value)
End Sub

Use it like this.

Sub test()
    Call transposeAndPasteRow(Worksheets("Sheet1").Range("A1:A5"), Worksheets("Sheet2").Range("A1"))
End Sub

Finally I got the perfect result what I want.

Here is my code.

self.semanticContentAttribute = .forceRightToLeft
self.contentHorizontalAlignment = .left

self.imageView?.translatesAutoresizingMaskIntoConstraints = false
self.imageView?.centerYAnchor.constraint(equalTo: self.centerYAnchor, constant: 0.0).isActive = true
self.imageView?.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 0.0).isActive = true

This code makes right text/left image button without any padding.

An application consists of one or more processes. A process, in the simplest terms, is an executing program. One or more threads run in the context of the process. A thread is the basic unit to which the operating system allocates processor time. A thread can execute any part of the process code, including parts currently being executed by another thread. A fiber is a unit of execution that must be manually scheduled by the application. Fibers run in the context of the threads that schedule them.

Stolen from here.

Just like you do for getting something from the CNode you also need to do for the ANode

XmlNodeList xnList = xml.SelectNodes("/Element[@*]");
foreach (XmlNode xn in xnList)
{
  XmlNode anode = xn.SelectSingleNode("ANode");
    if (anode!= null)
    {
        string id = anode["ID"].InnerText;
        string date = anode["Date"].InnerText;
        XmlNodeList CNodes = xn.SelectNodes("ANode/BNode/CNode");
        foreach (XmlNode node in CNodes)
        {
         XmlNode example = node.SelectSingleNode("Example");
         if (example != null)
         {
            string na = example["Name"].InnerText;
            string no = example["NO"].InnerText;
         }
        }
    }
}

Only this worked for me:

#container:hover .cube { background-color: yellow; }

Where .cube is CssClass of the #cube.

Tested in Firefox, Chrome and Edge.

The answers so far will work.. if you only want to use the height without padding, borders, etc.

If you would like to account for padding, borders, and margin, you should use .outerHeight.

var bottom = $('#bottom').position().top + $('#bottom').outerHeight(true);

Two of them always produce the same answer:

• COUNT(*) counts the number of rows
• COUNT(1) also counts the number of rows

Assuming the pk is a primary key and that no nulls are allowed in the values, then

• COUNT(pk) also counts the number of rows

However, if pk is not constrained to be not null, then it produces a different answer:

• COUNT(possibly_null) counts the number of rows with non-null values in the column possibly_null.

• COUNT(DISTINCT pk) also counts the number of rows (because a primary key does not allow duplicates).

• COUNT(DISTINCT possibly_null_or_dup) counts the number of distinct non-null values in the column possibly_null_or_dup.

• COUNT(DISTINCT possibly_duplicated) counts the number of distinct (necessarily non-null) values in the column possibly_duplicated when that has the NOT NULL clause on it.

Normally, I write COUNT(*); it is the original recommended notation for SQL. Similarly, with the EXISTS clause, I normally write WHERE EXISTS(SELECT * FROM ...) because that was the original recommend notation. There should be no benefit to the alternatives; the optimizer should see through the more obscure notations.

This problem can be caused by requests for certain files that don't exist. For example, requests for files in wp-content/uploads/ where the file does not exist.

If this is the situation you're seeing, you can solve the problem by going to .htaccess and changing this line:

RewriteRule ^(wp-(content|admin|includes).*) $1 [L]

to:

RewriteRule ^(wp-(content|admin|includes).*) - [L]

The underlying issue is that the rule above triggers a rewrite to the exact same url with a slash in front and because there was a rewrite, the newly rewritten request goes back through the rules again and the same rule is triggered. By changing that line's "$1" to "-", no rewrite happens and so the rewriting process does not start over again with the same URL.

It's possible that there's a difference in how apache 2.2 and 2.4 handle this situation of only-difference-is-a-slash-in-front and that's why the default rules provided by WordPress aren't working perfectly.

It means not equal to. The same as != seen in C style languages, as well as actionscript.

Change position:absolute to position:fixed;.

Example can be found in this jsFiddle.

If one's find does not have -mmin and if one also is stuck with a find that accepts only integer values for -mtime, then all is not necessarily lost if one considers that "older than" is similar to "not newer than".

If we were able to create a file that that has an mtime of our cut-off time, we can ask find to locate the files that are "not newer than" our reference file.

To create a file that has the correct time stamp is a bit involved because a system that doesn't have an adequate find probably also has a less-than-capable date command that could do things like: date +%Y%m%d%H%M%S -d "6 hours ago".

Fortunately, other old tools that can manage this, albeit in a more unwieldy way.

Consider that six hours is 21600 seconds. We want to find the time that is six hours ago in a format that is useful:

$ date && perl -e '@d=localtime time()-21600; \
  printf "%4d%02d%02d%02d%02d.%02d\n", $d[5]+1900,$d[4]+1,$d[3],$d[2],$d[1],$d[0]'
> Thu Apr 16 04:50:57 CDT 2020
202004152250.57

The perl statement did produce a useful date, but it has to be put to better use:

$ date && touch -t `perl -e '@d=localtime time()-21600; \
  printf "%4d%02d%02d%02d%02d.%02d\n", \
  $d[5]+1900,$d[4]+1,$d[3],$d[2],$d[1],$d[0]'` ref_file && ls -l ref_file
Thu Apr 16 04:53:54 CDT 2020
-rw-rw-rw-   1 root     sys            0 Apr 15 22:53 ref_file

Now the solution for this old UNIX is something along the lines of:

$ find . -type f ! -newer ref_file -a ! -name ref_file -exec rm -f "{}" \;

It might also be a good idea to clean up our reference file...

$ rm -f ref_file

If you don't mind using 3rd party libraries, my cyclops-react lib has extensions for all JDK Collection types, including Map. You can directly use the map or bimap methods to transform your Map. A MapX can be constructed from an existing Map eg.

  MapX<String, Column> y = MapX.fromMap(orgColumnMap)
                               .map(c->new Column(c.getValue());

If you also wish to change the key you can write

  MapX<String, Column> y = MapX.fromMap(orgColumnMap)
                               .bimap(this::newKey,c->new Column(c.getValue());

bimap can be used to transform the keys and values at the same time.

As MapX extends Map the generated map can also be defined as

  Map<String, Column> y

You can reference Microsoft.VisualBasic.dll.

Then using the code below.

Microsoft.VisualBasic.Interaction.InputBox("Question?","Title","Default Text");

Alternatively, by adding a using directive allowing for a shorter syntax in your code (which I'd personally prefer).

using Microsoft.VisualBasic;
...
Interaction.InputBox("Question?","Title","Default Text");

Or you can do what Pranay Rana suggests, that's what I would've done too...

Assuming you want to replace the newlines with something so that something like this:

the quick brown fox\r\n
jumped over the lazy dog\r\n

doesn't end up like this:

the quick brown foxjumped over the lazy dog

I'd do something like this:

string[] SplitIntoChunks(string text, int size)
{
    string[] chunk = new string[(text.Length / size) + 1];
    int chunkIdx = 0;
    for (int offset = 0; offset < text.Length; offset += size)
    {
        chunk[chunkIdx++] = text.Substring(offset, size);
    }
    return chunk;
}    

string[] GetComments()
{
    var cmtTb = GridView1.Rows[rowIndex].FindControl("txtComments") as TextBox; 
    if (cmtTb == null)
    {
        return new string[] {};
    }

    // I assume you don't want to run the text of the two lines together?
    var text = cmtTb.Text.Replace(Environment.Newline, " ");
    return SplitIntoChunks(text, 50);    
}

I apologize if the syntax isn't perfect; I'm not on a machine with C# available right now.

Exactly what you need:) You can choose callback version or Promise version. Note that promises will work in IE only with Promise polyfill lib.You can put this code once on a page, and this function will appear in all your files.

The loadend event is fired when progress has stopped on the loading of a resource (e.g. after "error", "abort", or "load" have been dispatched)

Callback version

        File.prototype.convertToBase64 = function(callback){
                var reader = new FileReader();
                reader.onloadend = function (e) {
                    callback(e.target.result, e.target.error);
                };   
                reader.readAsDataURL(this);
        };

        $("#asd").on('change',function(){
          var selectedFile = this.files[0];
          selectedFile.convertToBase64(function(base64){
               alert(base64);
          }) 
        });

Promise version

    File.prototype.convertToBase64 = function(){
         return new Promise(function(resolve, reject) {
                var reader = new FileReader();
                reader.onloadend = function (e) {
                    resolve({
                      fileName: this.name,
                      result: e.target.result, 
                      error: e.target.error
                    });
                };   
                reader.readAsDataURL(this);
        }.bind(this)); 
    };

    FileList.prototype.convertAllToBase64 = function(regexp){
      // empty regexp if not set
      regexp = regexp || /.*/;
      //making array from FileList
      var filesArray = Array.prototype.slice.call(this);
      var base64PromisesArray = filesArray.
           filter(function(file){
             return (regexp).test(file.name)
           }).map(function(file){
             return file.convertToBase64();
           });
      return Promise.all(base64PromisesArray);
    };

    $("#asd").on('change',function(){
      //for one file
      var selectedFile = this.files[0];
      selectedFile.convertToBase64().
          then(function(obj){
            alert(obj.result);
          });
      });
      //for all files that have file extention png, jpeg, jpg, gif
      this.files.convertAllToBase64(/\.(png|jpeg|jpg|gif)$/i).then(function(objArray){
            objArray.forEach(function(obj, i){
                  console.log("result[" + obj.fileName + "][" + i + "] = " + obj.result);
            });
      });
    })

You seem to be confusing asynchronous IO with asynchronous functions. node.js uses asynchronous non-blocking IO because non blocking IO is better. The best way to understand it is to go watch some videos by ryan dahl.

How do I write asynchronous functions for Node?

Just write normal functions, the only difference is that they are not executed immediately but passed around as callbacks.

How should I implement error event handling correctly

Generally API's give you a callback with an err as the first argument. For example

database.query('something', function(err, result) {
  if (err) handle(err);
  doSomething(result);
});

Is a common pattern.

Another common pattern is on('error'). For example

process.on('uncaughtException', function (err) {
  console.log('Caught exception: ' + err);
});

Edit:

var async_function = function(val, callback){
    process.nextTick(function(){
        callback(val);
    });
};

The above function when called as

async_function(42, function(val) {
  console.log(val)
});
console.log(43);

Will print 42 to the console asynchronously. In particular process.nextTick fires after the current eventloop callstack is empty. That call stack is empty after async_function and console.log(43) have run. So we print 43 followed by 42.

You should probably do some reading on the event loop.

I had to rescale the bitmap a bit to not exceed the 1mb limit of the transaction binder. You can adapt the 400 the your screen or make it dinamic it's just meant to be an example. It works fine and the quality is nice. Its also a lot faster then saving the image and loading it after but you have the size limitation.

public void loadNextActivity(){
    Intent confirmBMP = new Intent(this,ConfirmBMPActivity.class);

    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    Bitmap bmp = returnScaledBMP();
    bmp.compress(Bitmap.CompressFormat.JPEG, 100, stream);

    confirmBMP.putExtra("Bitmap",bmp);
    startActivity(confirmBMP);
    finish();

}
public Bitmap returnScaledBMP(){
    Bitmap bmp=null;
    bmp = tempBitmap;
    bmp = createScaledBitmapKeepingAspectRatio(bmp,400);
    return bmp;

}

After you recover the bmp in your nextActivity with the following code:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_confirmBMP);
    Intent intent = getIntent();
    Bitmap bitmap = (Bitmap) intent.getParcelableExtra("Bitmap");

}

I hope my answer was somehow helpfull. Greetings

This is similar to the solution referred by Mark Heath but with not as much code to just create a very basic button, without the built-in mouse over animation effect. It preserves a simple mouse over effect of showing the button border in black.

The style can be inserted into the Window.Resources or UserControl.Resources section for example (as shown).

<UserControl.Resources>
    <!-- This style is used for buttons, to remove the WPF default 'animated' mouse over effect -->
    <Style x:Key="MyButtonStyle" TargetType="Button">

        <Setter Property="Margin" Value="5"/>
        <Setter Property="Template">

                        BorderThickness="1"
                        Padding="4,2" 
                        BorderBrush="DarkGray" 
                        CornerRadius="3"

FYI, I've got the same error from Chrome console. I thought my AJAX function causing it, but I uncommented my minified script from /javascripts/ajax-vanilla.min.js to /javascripts/ajax-vanilla.js. But in reality the source file was at /javascripts/src/ajax-vanilla.js. So in Chrome you getting bad MIME type error even if the file cannot be found. In this case, the error message is described as text/plain bad MIME type.

this is Postgres UPDATE JOIN format:

The easiest way would be to create a new (simple) Maven project using the "new project" wizard. You can then migrate your source into the Maven folder structure + the auto generated POM file.

Suppose you want to show (50% OFF) and enter 50 at runtime. Here is the code:

<string name="format_discount"> (
<xliff:g id="discount">%1$s</xliff:g>
<xliff:g id="percentage_sign">%2$s</xliff:g>
 OFF)</string>

In the java class use this code:

String formattedString=String.format(context.getString(R.string.format_discount),discountString,"%");
holder1.mTextViewDiscount.setText(formattedString);

Run DBCC CHECKTABLE('table_name');

Check the LOG folder where the isntance is installed (\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG usually) for any file named 'SQLDUMP*'

You can use django's filter with datetime.date objects:

import datetime
samples = Sample.objects.filter(sampledate__gte=datetime.date(2011, 1, 1),
                                sampledate__lte=datetime.date(2011, 1, 31))

There are ways of paying less to get an application, developed than paying the going rate, but very often you get what you pay for - inexperienced developers who leave you with a mess of spaghetti code that's impossible to maintain, or experienced developers with whom you have to communicate across a cultural and language gap.

Developing an app like Twitterific is not easy. It's an extraordinarily polished app with a lot of attention to detail that most people - indeed many developers - would fail to notice or realize the effort behind. You may be able to get a Twitter iPhone client written for $3500 or $5000 by going offshore or by being willing to "work with inexperienced developers", but you're not going to get Twitterific for that, and it's doubtful you'd get even a halfway decent application for that amount.

And you likely will end up spending a lot of time managing the process, going back and forth on requirements, and fighting to get what you really want instead of what they want to give you.

There's also a risk with "cut-rate" development, whether it's offshore or just using inexperienced developers - you may very well end up with something you can't use, or something that gets 1 star ratings because it crashes or behaves erratically. You might find the occasional underpriced gem of a developer, but they won't stay underpriced for long given the sheer demand in this market right now.

By virtue of my books and blog, people often reach out to me when they need help with their iPhone applications. I get, on average, 4 or 5 inquiries a month from people asking for help fixing applications they had developed either over-seas or by inexperienced developers here in the States. In most cases, I end up having to tell them they'd be better off throwing their code out and starting over with a developer who knows what they're doing rather than trying to fix the code they bought on the cheap. If they insist on trying to "fix" what they have, I decline the work.

Improved One-Liner answer: If you are looking for a boolean return value, we can do it better by adding isPresent:

return dataSource.getParkingLots().stream().filter(parkingLot -> Objects.equals(parkingLot.getId(), id)).findFirst().isPresent();

Some reading to get you started on character encodings: Joel on Software: The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)

By the way - ASP.NET has nothing to do with it. Encodings are universal.

As a basic example...

HTML:

<input type="text" name="Thing" value="" />

Script:

/* event listener */
document.getElementsByName("Thing")[0].addEventListener('change', doThing);

/* function */
function doThing(){
   alert('Horray! Someone wrote "' + this.value + '"!');
}

Here's a fiddle: http://jsfiddle.net/Niffler/514gg4tk/

module.exports and exports both point to the same object before the module is evaluated.

Any property you add to the module.exports object will be available when your module is used in another module using require statement. exports is a shortcut made available for the same thing. For instance:

module.exports.add = (a, b) => a+b

is equivalent to writing:

exports.add = (a, b) => a+b

So it is okay as long as you do not assign a new value to exports variable. When you do something like this:

exports = (a, b) => a+b 

as you are assigning a new value to exports it no longer has reference to the exported object and thus will remain local to your module.

If you are planning to assign a new value to module.exports rather than adding new properties to the initial object made available, you should probably consider doing as given below:

module.exports = exports = (a, b) => a+b

Node.js website has a very good explanation of this.

createOrReplaceTempView creates (or replaces if that view name already exists) a lazily evaluated "view" that you can then use like a hive table in Spark SQL. It does not persist to memory unless you cache the dataset that underpins the view.

scala> val s = Seq(1,2,3).toDF("num")
s: org.apache.spark.sql.DataFrame = [num: int]

scala> s.createOrReplaceTempView("nums")

scala> spark.table("nums")
res22: org.apache.spark.sql.DataFrame = [num: int]

scala> spark.table("nums").cache
res23: org.apache.spark.sql.Dataset[org.apache.spark.sql.Row] = [num: int]

scala> spark.table("nums").count
res24: Long = 3

The data is cached fully only after the .count call. Here's proof it's been cached:

Related SO: spark createOrReplaceTempView vs createGlobalTempView

Relevant quote (comparing to persistent table): "Unlike the createOrReplaceTempView command, saveAsTable will materialize the contents of the DataFrame and create a pointer to the data in the Hive metastore." from https://spark.apache.org/docs/latest/sql-programming-guide.html#saving-to-persistent-tables

Note : createOrReplaceTempView was formerly registerTempTable

It's just as simple as command+s or File > Save Screen Shot in iOS Simulator. It will appear on your desktop by default.

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

How to transfer putty configuration and session configuration from one user account to another e.g. when created a new account and want to use the putty sessions/configurations from the old account

Process:
- Export registry key from old account into a file
- Import registry key from file into new account

Export reg key: (from OLD account)

1. Login into the OLD account e.g. tomold
2. Open normal 'command prompt' (NOT admin !)
3. Type 'regedit'
4. Navigate to registry section where the configuration is being stored e.g. [HKEY_CURRENT_USER\SOFTWARE\SimonTatham] and click on it
5. Select 'Export' from the file menu or right mouse click (radio ctrl 'selected branch')
6. Save into file and name it e.g. 'puttyconfig.reg'
7. Logout again

Import reg key: (into NEW account)

8. Login into NEW account e.g. tom

9. Open normal 'command prompt' (NOT admin !)

10. Type 'regedit'

11. Select 'Import' from the menu

12. Select the registry file to import e.g. 'puttyconfig.reg'

13. Done

Note:
Do not use an 'admin command prompt' as settings are located under '[HKEY_CURRENT_USER...] 'and regedit would run as admin and show that section for the admin-user rather then for the user to transfer from and/or to.

This one works for me:

return Paths.get(ClassLoader.getSystemResource(resourceName).toURI());

Here you go:

DECLARE
BEGIN
  dbms_output.enable(NULL); -- Disables the limit of DBMS
  -- Your print here !
END;

Try to create script with ADD command and specification of working directory Like this("script" is the name of script and /root/script.sh is where you want it in the container, it can be different path:

ADD script.sh /root/script.sh

In this case ADD has to come before CMD, if you have one BTW it's cool way to import scripts to any location in container from host machine

In CMD place [./script]

It should automatically execute your script

You can also specify WORKDIR as /root, then you'l be automatically placed in root, upon starting a container

This debugging code should do the trick well:

You can explore the properties of the Screen Class

Put all displays in an array or list using Screen.AllScreens then capture the index of the current display and its properties.

C# (Converted from VB by Telerik - Please double check)

        {
    List<Screen> arrAvailableDisplays = new List<Screen>();
    List<string> arrDisplayNames = new List<string>();

    foreach (Screen Display in Screen.AllScreens)
    {
        arrAvailableDisplays.Add(Display);
        arrDisplayNames.Add(Display.DeviceName);
    }

    Screen scrCurrentDisplayInfo = Screen.FromControl(this);
    string strDeviceName = Screen.FromControl(this).DeviceName;
    int idxDevice = arrDisplayNames.IndexOf(strDeviceName);

    MessageBox.Show(this, "Number of Displays Found: " + arrAvailableDisplays.Count.ToString() + Constants.vbCrLf + "ID: " + idxDevice.ToString() + Constants.vbCrLf + "Device Name: " + scrCurrentDisplayInfo.DeviceName.ToString + Constants.vbCrLf + "Primary: " + scrCurrentDisplayInfo.Primary.ToString + Constants.vbCrLf + "Bounds: " + scrCurrentDisplayInfo.Bounds.ToString + Constants.vbCrLf + "Working Area: " + scrCurrentDisplayInfo.WorkingArea.ToString + Constants.vbCrLf + "Bits per Pixel: " + scrCurrentDisplayInfo.BitsPerPixel.ToString + Constants.vbCrLf + "Width: " + scrCurrentDisplayInfo.Bounds.Width.ToString + Constants.vbCrLf + "Height: " + scrCurrentDisplayInfo.Bounds.Height.ToString + Constants.vbCrLf + "Work Area Width: " + scrCurrentDisplayInfo.WorkingArea.Width.ToString + Constants.vbCrLf + "Work Area Height: " + scrCurrentDisplayInfo.WorkingArea.Height.ToString, "Current Info for Display '" + scrCurrentDisplayInfo.DeviceName.ToString + "' - ID: " + idxDevice.ToString(), MessageBoxButtons.OK, MessageBoxIcon.Information);
}

VB (Original code)

 Dim arrAvailableDisplays As New List(Of Screen)()
    Dim arrDisplayNames As New List(Of String)()

    For Each Display As Screen In Screen.AllScreens
        arrAvailableDisplays.Add(Display)
        arrDisplayNames.Add(Display.DeviceName)
    Next

    Dim scrCurrentDisplayInfo As Screen = Screen.FromControl(Me)
    Dim strDeviceName As String = Screen.FromControl(Me).DeviceName
    Dim idxDevice As Integer = arrDisplayNames.IndexOf(strDeviceName)

    MessageBox.Show(Me,
                    "Number of Displays Found: " + arrAvailableDisplays.Count.ToString & vbCrLf &
                    "ID: " & idxDevice.ToString + vbCrLf &

Based on previous functions found in this post. Added recursive mode and indentation.

function dump(v, s) {
  s = s || 1;
  var t = '';
  switch (typeof v) {
    case "object":
      t += "\n";
      for (var i in v) {
        t += Array(s).join(" ")+i+": ";
        t += dump(v[i], s+3);
      }
      break;
    default: //number, string, boolean, null, undefined 
      t += v+" ("+typeof v+")\n";
      break;
  }
  return t;
}

Example

var a = {
  b: 1,
  c: {
    d:1,
    e:2,
    d:3,
    c: {
      d:1,
      e:2,
      d:3
    }
  }
};

var d = dump(a);
console.log(d);
document.getElementById("#dump").innerHTML = "<pre>" + d + "</pre>";

Result

b: 1 (number)
c: 
   d: 3 (number)
   e: 2 (number)
   c: 
      d: 3 (number)
      e: 2 (number)

Some languages have combining diacritics as language letters and accent diacritics to specify accent.

I think it is more safe to specify explicitly what diactrics you want to strip:

def strip_accents(string, accents=('COMBINING ACUTE ACCENT', 'COMBINING GRAVE ACCENT', 'COMBINING TILDE')):
    accents = set(map(unicodedata.lookup, accents))
    chars = [c for c in unicodedata.normalize('NFD', string) if c not in accents]
    return unicodedata.normalize('NFC', ''.join(chars))

Try this way header('Content-Type: text/plain; charset=utf-8');

In addition to other answers, which told you how to do what you wanted, I try to explain what was wrong (which is what you wanted.

In Bash, if is to be followed with a command. If the exit code of this command is equal to 0, then the then part is executed, else the else part if any is executed.

You can do that with any command as explained in other answers: if /bin/true; then ...; fi

[[ is an internal bash command dedicated to some tests, like file existence, variable comparisons. Similarly [ is an external command (it is located typically in /usr/bin/[) that performs roughly the same tests but needs ] as a final argument, which is why ] must be padded with a space on the left, which is not the case with ]].

Here you needn't [[ nor [.

Another thing is the way you quote things. In bash, there is only one case where pairs of quotes do nest, it is "$(command "argument")". But in 'grep 'SomeString' $File' you have only one word, because 'grep ' is a quoted unit, which is concatenated with SomeString and then again concatenated with ' $File'. The variable $File is not even replaced with its value because of the use of single quotes. The proper way to do that is grep 'SomeString' "$File".

If your options are like this

var options = [
  { value: 'one', label: 'One' },
  { value: 'two', label: 'Two' }
];

Your {props.input.value} should match one of the 'value' in your {props.options}

Meaning, props.input.value should be either 'one' or 'two'

A.) The command is NOT EXISTS, you're missing the 'S'.

B.) Use NOT IN instead

SELECT ip 
  FROM login_log 
  WHERE ip NOT IN (
    SELECT ip
    FROM ip_location
  )
;

SQLite Boolean Datatype:
SQLite does not have a separate Boolean storage class. Instead, Boolean values are stored as integers 0 (false) and 1 (true).

You can convert boolean to int in this way:

int flag = (boolValue)? 1 : 0;

You can convert int back to boolean as follows:

 // Select COLUMN_NAME  values from db. 
 // This will be integer value, you can convert this int value back to Boolean as follows
Boolean flag2 = (intValue == 1)? true : false;

If you want to explore sqlite, here is a tutorial.
I have given one answer here. It is working for them.

it is wrong. correct will be

P3 P2 P4 P5 P1 0 3 4 6 10 as the correct difference are these

Waiting Time (0+3+4+6+10)/5 = 4.6

It's easy just add the name which you want to use in quotes before adding vector

a_matrix <- cbind(b_matrix,'Name-Change'= c_vector)

This is what matplotlib.pyplot.scatter is for.

As a quick example:

import matplotlib.pyplot as plt
import numpy as np

# Generate data...
t = np.linspace(0, 2 * np.pi, 20)
x = np.sin(t)
y = np.cos(t)

plt.scatter(t,x,c=y)
plt.show()

If you want to change the card background color, use:

app:cardBackgroundColor="@somecolor"

like this:

<android.support.v7.widget.CardView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:cardBackgroundColor="@color/white">

</android.support.v7.widget.CardView>

Edit: As pointed by @imposible, you need to include

xmlns:app="http://schemas.android.com/apk/res-auto"

in your root XML tag in order to make this snippet function

You may require to install Language Packs: 3.2

or just

show table status;

just that this will llist all tables on your database.

The quintessential example of this is an array of pointers to structs or objects (that are mutable).

A shallow copy copies the array and maintains references to the original objects.

A deep copy will copy (clone) the objects too so they bear no relation to the original. Implicit in this is that the object themselves are deep copied. This is where it gets hard because there's no real way to know if something was deep copied or not.

The copy constructor is used to initilize the new object with the previously created object of the same class. By default compiler wrote a shallow copy. Shallow copy works fine when dynamic memory allocation is not involved because when dynamic memory allocation is involved then both objects will points towards the same memory location in a heap, Therefore to remove this problem we wrote deep copy so both objects have their own copy of attributes in a memory.

In order to read the details with complete examples and explanations you could see the article Constructors and destructors.

The default copy constructor is shallow. You can make your own copy constructors deep or shallow, as appropriate. See C++ Notes: OOP: Copy Constructors.

As mentioned in other posts, the combination of css values of overflow: auto; & -webkit-overflow-scrolling: touch;

works when applied to BOTH the iframe in question AND its parent div

With the unfortunate side-effect of double scrollbars on non-touch browsers.

The solution I used was to add these css values via javascript/jquery. Which allowed me to use a base css for all browsers

if (isSafariBrowser()){
    $('#parentDivID').css('overflow', 'auto');
    $('#parentDivID').css('-webkit-overflow-scrolling', 'touch');
    $('#iframeID').css('overflow', 'auto');
    $('#iframeID').css('-webkit-overflow-scrolling', 'touch');
}

where isSafariBrowser() is defined as foll...

var is_chrome = navigator.userAgent.indexOf('Chrome') > -1;
var is_safari = navigator.userAgent.indexOf("Safari") > -1;

function isSafariBrowser(){
    if (is_safari){
        if (is_chrome)  // Chrome seems to have both Chrome and Safari userAgents
            return false;
        else
            return true;
    }
    return false;
}

This allowed my application to work on an iPad Note 1) Not tested on other ios systems 2) Not tested this on Android browsers on tablets, may need additional changes

(so this solution may not be complete)

Do you mean full calendar days, or groups of 24 hours?

For simply 24 hours, assuming you're using Python's datetime, then the timedelta object already has a days property:

days = (a - b).days

For calendar days, you'll need to round a down to the nearest day, and b up to the nearest day, getting rid of the partial day on either side:

roundedA = a.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
roundedB = b.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
days = (roundedA - roundedB).days

Sorry for I did not explain my answer really well at beginning. There is another way to add an new column to an existing dataframe. 1st step, make a new empty data frame (with all the columns in your data frame, plus a new or few columns you want to add) called df_temp 2nd step, combine the df_temp and your data frame.

df_temp = pd.DataFrame(columns=(df_null.columns.tolist() + ['empty']))
df = pd.concat([df_temp, df])

It might be the best solution, but it is another way to think about this question.

the reason of I am using this method is because I am get this warning all the time:

: SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_indexer,col_indexer] = value instead

See the caveats in the documentation: https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy
  df["empty1"], df["empty2"] = [np.nan, ""]

great I found the way to disable the Warning

pd.options.mode.chained_assignment = None 

You can even simply add the parameters to the end of the url:

$http.get('path/to/script.php?param=hello').success(function(data) {
    alert(data);
});

Paired with script.php:

<? var_dump($_GET); ?>

Resulting in the following javascript alert:

array(1) {  
    ["param"]=>  
    string(4) "hello"
}

2 things.

• The query has to complete on sql server before the return value is sent.

• The results have to be captured and then finish executing before the return value gets to the object.

In English, finish the work and then retrieve the value.

this will not work:

                cmm.ExecuteReader();
                int i = (int) cmm.Parameters["@RETURN_VALUE"].Value;

This will work:

                        SqlDataReader reader = cmm.ExecuteReader();
                        reader.Close();

                        foreach (SqlParameter prm in cmd.Parameters)
                        {
                           Debug.WriteLine("");
                           Debug.WriteLine("Name " + prm.ParameterName);
                           Debug.WriteLine("Type " + prm.SqlDbType.ToString());
                           Debug.WriteLine("Size " + prm.Size.ToString());
                           Debug.WriteLine("Direction " + prm.Direction.ToString());
                           Debug.WriteLine("Value " + prm.Value);

                        }

if you are not sure check the value of the parameter before during and after the results have been processed by the reader.

$HOME/.gitconfig is your global config for git.
There are three levels of config files.

 cat $(git rev-parse --show-toplevel)/.git/config

(mentioned by bereal) is your local config, local to the repo you have cloned.

you can also type from within your repo:

git remote -v

And see if there is any remote named 'origin' listed in it.

If not, if that remote (which is created by default when cloning a repo) is missing, you can add it again:

git remote add origin url/to/your/fork

The OP mentions:

Doing git remote -v gives:

upstream git://git.moodle.org/moodle.git (fetch) 
upstream git://git.moodle.org/moodle.git (push)

So 'origin' is missing: the reference to your fork.
See "What is the difference between origin and upstream in github"

you can extend LinkedHashSet adding your desired getIndex() method. It's 15 minutes to implement and test it. Just go through the set using iterator and counter, check the object for equality. If found, return the counter.

For a production system, you can use this configuration :

--ACCESS DB
REVOKE CONNECT ON DATABASE nova FROM PUBLIC;
GRANT  CONNECT ON DATABASE nova  TO user;

--ACCESS SCHEMA
REVOKE ALL     ON SCHEMA public FROM PUBLIC;
GRANT  USAGE   ON SCHEMA public  TO user;

--ACCESS TABLES
REVOKE ALL ON ALL TABLES IN SCHEMA public FROM PUBLIC ;
GRANT SELECT                         ON ALL TABLES IN SCHEMA public TO read_only ;
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO read_write ;
GRANT ALL                            ON ALL TABLES IN SCHEMA public TO admin ;

Update (2017): The following two libraries have now become the most common drop-down libraries used with Javascript. While they are jQuery-native, they have been customized to work with everything from AngularJS 1.x to having custom CSS for Bootstrap. (Chosen JS, the original answer here, seems to have dropped to #3 in popularity.)

Original answer (2012): I think that the Chosen library might also be useful. Its available in jQuery, Prototype and MooTools versions.

Depending on what exactly you require, a Server.Transfer might be a resource-cheaper alternative to Response.Redirect. More information is in Server.Transfer Vs. Response.Redirect.

In summary, the most reliable way to have MiniDLNA rescan all media files is by issuing the following set of commands:

$ sudo minidlnad -R
$ sudo service minidlna restart

Client-side script to rescan server

However, every so often MiniDLNA will be running on a server. Here is a client-side script to request a rescan on such a server:

#!/usr/bin/env bash
ssh -t server.on.lan 'sudo minidlnad -R && sudo service minidlna restart'

I have used in this way.. Working fine!

 $inputs = request()->validate([
        'name' => 'required | min:6 | max: 20',
        'email' => 'required',
        'password' => 'required| min:4| max:7 |confirmed',
        'password_confirmation' => 'required| min:4'
  ]);

Linux

In Linux, this information is available in the /proc file system. I'm not a big fan of the text file format used, as each Linux distribution seems to customize at least one important file. A quick look as the source to 'ps' reveals the mess.

But here is where to find the information you seek:

/proc/meminfo contains the majority of the system-wide information you seek. Here it looks like on my system; I think you are interested in MemTotal, MemFree, SwapTotal, and SwapFree:

For CPU utilization, you have to do a little work. Linux makes available overall CPU utilization since system start; this probably isn't what you are interested in. If you want to know what the CPU utilization was for the last second, or 10 seconds, then you need to query the information and calculate it yourself.

The information is available in /proc/stat, which is documented pretty well at http://www.linuxhowtos.org/System/procstat.htm; here is what it looks like on my 4-core box:

Anderson cxc #  more /proc/stat
cpu  2329889 0 2364567 1063530460 9034 9463 96111 0

First, you need to determine how many CPUs (or processors, or processing cores) are available in the system. To do this, count the number of 'cpuN' entries, where N starts at 0 and increments. Don't count the 'cpu' line, which is a combination of the cpuN lines. In my example, you can see cpu0 through cpu3, for a total of 4 processors. From now on, you can ignore cpu0..cpu3, and focus only on the 'cpu' line.

Next, you need to know that the fourth number in these lines is a measure of idle time, and thus the fourth number on the 'cpu' line is the total idle time for all processors since boot time. This time is measured in Linux "jiffies", which are 1/100 of a second each.

But you don't care about the total idle time; you care about the idle time in a given period, e.g., the last second. Do calculate that, you need to read this file twice, 1 second apart.Then you can do a diff of the fourth value of the line. For example, if you take a sample and get:

cpu  2330047 0 2365006 1063853632 9035 9463 96114 0

Then one second later you get this sample:

cpu  2330047 0 2365007 1063854028 9035 9463 96114 0

Subtract the two numbers, and you get a diff of 396, which means that your CPU had been idle for 3.96 seconds out of the last 1.00 second. The trick, of course, is that you need to divide by the number of processors. 3.96 / 4 = 0.99, and there is your idle percentage; 99% idle, and 1% busy.

In my code, I have a ring buffer of 360 entries, and I read this file every second. That lets me quickly calculate the CPU utilization for 1 second, 10 seconds, etc., all the way up to 1 hour.

For the process-specific information, you have to look in /proc/pid; if you don't care abut your pid, you can look in /proc/self.

CPU used by your process is available in /proc/self/stat. This is an odd-looking file consisting of a single line; for example:

19340 (whatever) S 19115 19115 3084 34816 19115 4202752 118200 607 0 0 770 384 2
 7 20 0 77 0 266764385 692477952 105074 4294967295 134512640 146462952 321468364
8 3214683328 4294960144 0 2147221247 268439552 1276 4294967295 0 0 17 0 0 0 0

The important data here are the 13th and 14th tokens (0 and 770 here). The 13th token is the number of jiffies that the process has executed in user mode, and the 14th is the number of jiffies that the process has executed in kernel mode. Add the two together, and you have its total CPU utilization.

Again, you will have to sample this file periodically, and calculate the diff, in order to determine the process's CPU usage over time.

Edit: remember that when you calculate your process's CPU utilization, you have to take into account 1) the number of threads in your process, and 2) the number of processors in the system. For example, if your single-threaded process is using only 25% of the CPU, that could be good or bad. Good on a single-processor system, but bad on a 4-processor system; this means that your process is running constantly, and using 100% of the CPU cycles available to it.

For the process-specific memory information, you ahve to look at /proc/self/status, which looks like this:

Name:   whatever
State:  S (sleeping)

The entries that start with 'Vm' are the interesting ones:

• VmPeak is the maximum virtual memory space used by the process, in kB (1024 bytes).
• VmSize is the current virtual memory space used by the process, in kB. In my example, it's pretty large: 651,352 kB, or about 636 megabytes.
• VmRss is the amount of memory that have been mapped into the process' address space, or its resident set size. This is substantially smaller (420,296 kB, or about 410 megabytes). The difference: my program has mapped 636 MB via mmap(), but has only accessed 410 MB of it, and thus only 410 MB of pages have been assigned to it.

The only item I'm not sure about is Swapspace currently used by my process. I don't know if this is available.

I have modified the version taken from AngularJS that implements a dependency injection mechanism to work without Angular. I have also updated the STRIP_COMMENTS regex to work with ECMA6, so it supports things like default values in the signature.

A neat solution with O(n) runtime:

1. For each element calculate the product of all the elements that occur before that and it store in an array "pre".
2. For each element calculate the product of all the elements that occur after that element and store it in an array "post"

3. Create a final array "result", for an element i,

   result[i] = pre[i-1]*post[i+1];
   

This solution uses an Asynchronous call. It will likely work better than a synchronous solution.

var request = new XMLHttpRequest();
request.open("GET", "../../data/file.json", false);
request.send(null);
request.onreadystatechange = function() {
  if ( request.readyState === 4 && request.status === 200 ) {
    var my_JSON_object = JSON.parse(request.responseText);
    console.log(my_JSON_object);
  }
}

It allows for further querying further down the line. If this was beyond a service boundary say, then the user of this IQueryable object would be allowed to do more with it.

For instance if you were using lazy loading with nhibernate this might result in graph being loaded when/if needed.

<script type="text/javascript">
    document.write("<p>" + Date() + "</p>");
</script>

Is a good example.

There are a few things interacting here:

1. docker run your_image arg1 arg2 will replace the value of CMD with arg1 arg2. That's a full replacement of the CMD, not appending more values to it. This is why you often see docker run some_image /bin/bash to run a bash shell in the container.

2. When you have both an ENTRYPOINT and a CMD value defined, docker starts the container by concatenating the two and running that concatenated command. So if you define your entrypoint to be file.sh, you can now run the container with additional args that will be passed as args to file.sh.

3. Entrypoints and Commands in docker have two syntaxes, a string syntax that will launch a shell, and a json syntax that will perform an exec. The shell is useful to handle things like IO redirection, chaining multiple commands together (with things like &&), variable substitution, etc. However, that shell gets in the way with signal handling (if you've ever seen a 10 second delay to stop a container, this is often the cause) and with concatenating an entrypoint and command together. If you define your entrypoint as a string, it would run /bin/sh -c "file.sh", which alone is fine. But if you have a command defined as a string too, you'll see something like /bin/sh -c "file.sh" /bin/sh -c "arg1 arg2" as the command being launched inside your container, not so good. See the table here for more on how these two options interact

4. The shell -c option only takes a single argument. Everything after that would get passed as $1, $2, etc, to that single argument, but not into an embedded shell script unless you explicitly passed the args. I.e. /bin/sh -c "file.sh $1 $2" "arg1" "arg2" would work, but /bin/sh -c "file.sh" "arg1" "arg2" would not since file.sh would be called with no args.

Putting that all together, the common design is:

FROM ubuntu:14.04
COPY ./file.sh /
RUN chmod 755 /file.sh
# Note the json syntax on this next line is strict, double quotes, and any syntax
# error will result in a shell being used to run the line.
ENTRYPOINT ["file.sh"]

And you then run that with:

docker run your_image arg1 arg2

There's a fair bit more detail on this at:

• https://docs.docker.com/engine/reference/run/#cmd-default-command-or-options
• https://docs.docker.com/engine/reference/builder/#exec-form-entrypoint-example

if you are going to do a query you can join in your Inline Table Valued function like:

SELECT
    a.*,b.*
    FROM AAAA a
        INNER JOIN MyNS.GetUnshippedOrders() b ON a.z=b.z

it will incur little overhead and run fine.

if you try to use your the Multi Statement Table Valued in a similar query, you will have performance issues:

SELECT
    x.a,x.b,x.c,(SELECT OrderQty FROM MyNS.GetLastShipped(x.CustomerID)) AS Qty
    FROM xxxx   x

because you will execute the function 1 time for each row returned, as the result set gets large, it will run slower and slower.

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

If you have access to the remote repo from a shell, just go into the .git (or the main dir if its a bare repo) and change the HEAD file to point to the correct head. For example, by default it always contains 'refs: refs/heads/master', but if you need foo to be the HEAD instead, just edit the HEAD file and change the contents to 'refs: refs/heads/foo'.

Good question.

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

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

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

COPY tablename TO '/tmp/output.csv' DELIMITER ',' CSV HEADER;

this command is used to store the entire table as csv

In my opinion errors have a reason to appear, that my sound stupid, but thats the way it is. Good programming only raises errors when you have to handle them. Also, as i read some time ago, "the pass-Statement is a Statement that Shows code will be inserted later", so if you want to have an empty except-statement feel free to do so, but for a good program there will be a part missing. because you dont handle the things you should have. Appearing exceptions give you the chance to correct input data or to change your data structure so these exceptions dont occur again (but in most cases (Network-exceptions, General input-exceptions) exceptions indicate that the next parts of the program wont execute well. For example a NetworkException can indicate a broken network-connection and the program cant send/recieve data in the next program steps.

But using a pass block for only one execption-block is valid, because you still differenciate beetween the types of exceptions, so if you put all exception-blocks in one, it is not empty:

try:
    #code here
except Error1:
    #exception handle1

except Error2:
    #exception handle2
#and so on

can be rewritten that way:

try:
    #code here
except BaseException as e:
    if isinstance(e, Error1):
        #exception handle1

    elif isinstance(e, Error2):

So even multiple except-blocks with pass-statements can result in code, whose structure handles special types of exceptions.

There is a growing number of Open Source and commercial solutions for pure JavaScript charting that do not require Flash. In this response I will only present Open Source options.

There are 2 main classes of JavaScript solutions for graphics that do not require Flash:

• Canvas-based, rendered in IE using ExplorerCanvas that in turns relies on VML
• SVG on standard-based browsers, rendered as VML in IE

There are pros and cons of both approaches but for a charting library I would recommend the later because it is well integrated with DOM, allowing to manipulate charts elements with the DOM, and most importantly setting DOM events. By contrast Canvas charting libraries must reinvent the DOM wheel to manage events. So unless you intend to build static graphs with no event handling, SVG/VML solutions should be better.

For SVG/VML solutions there are many options, including:

• Dojox Charting, good if you use the Dojo toolkit already
• Raphael-based solutions

Raphael is a very active, well maintained, and mature, open-source graphic library with very good cross-browser support including IE 6 to 8, Firefox, Opera, Safari, Chrome, and Konqueror. Raphael does not depend on any JavaScript framework and therefore can be used with Prototype, jQuery, Dojo, Mootools, etc...

There are a number of charting libraries based on Raphael, including (but not limited to):

• gRaphael, an extension of the Raphael graphic library
• Ico, with an intuitive API based on a single function call to create complex charts

Disclosure: I am the developer of one of the Ico forks on github.

Try this:

foreach (DataGridViewRow item in this.YourGridViewName.SelectedRows)
{
    string ConnectionString = (@"Data Source=DESKTOPQJ1JHRG\SQLEXPRESS;Initial Catalog=smart_movers;Integrated Security=True");

    SqlConnection conn = new SqlConnection(ConnectionString);
    conn.Open();
    SqlCommand cmd = new SqlCommand("DELETE FROM TableName WHERE ColumnName =@Index", conn);
    cmd.Parameters.AddWithValue("@Index", item.Index);
    int i = cmd.ExecuteNonQuery();

    if (i != 0)
    {
        YourGridViewName.Rows.RemoveAt(item.Index);
        MessageBox.Show("Deleted Succefull!", "Great", MessageBoxButtons.OK, MessageBoxIcon.Information);
    }
    else {
        MessageBox.Show("Deleted Failed!", "Failed", MessageBoxButtons.OK, MessageBoxIcon.Error);
    }
}

API token is the same as password from API point of view, see source code uses token in place of passwords for the API.

This is covered by Python 3 Subprocess Examples under "Wait for command to terminate asynchronously":

import asyncio

proc = await asyncio.create_subprocess_exec(
    'ls','-lha',
    stdout=asyncio.subprocess.PIPE,
    stderr=asyncio.subprocess.PIPE)

# do something else while ls is working

# if proc takes very long to complete, the CPUs are free to use cycles for 
# other processes
stdout, stderr = await proc.communicate()

The process will start running as soon as the await asyncio.create_subprocess_exec(...) has completed. If it hasn't finished by the time you call await proc.communicate(), it will wait there in order to give you your output status. If it has finished, proc.communicate() will return immediately.

The gist here is similar to Terrels answer but I think Terrels answer appears to overcomplicate things.

See asyncio.create_subprocess_exec for more information.

[1]: http://www.jasom.net/how-to-install-curl-command-manually-on-debian-linux. This is its shortcut:

1. cd /usr/local/src
2. wget http://curl.haxx.se/download/curl-7.36.0.tar.gz
3. tar -xvzf curl-7.36.0.tar.gz
4. rm *.gz
5. cd curl-7.6.0

7. make
8. make install

And restart Apache. If you will have an error during point 6, try to run apt-get install build-essential.

Creating an sqlite connection to a file on disk is left as an exercise for the reader ... but there is now a two-liner made possible by the pandas library

df = pandas.read_csv(csvfile)
df.to_sql(table_name, conn, if_exists='append', index=False)

It can be solved by using different attribute.

• Use the cell Control click event.
• Select the column value that your transpose to anther column.
• send the selected value to the another text box or level whatever you fill convenient and a complementary button to modify the selected property.
• update the whole stack op the database and make a algorithm with sql query to overcome this one to transpose it into the another column.

There are a lot of solutions to this question already, but I wanted to post one that:

• Doesn't use a library depricated in API 3
• Calculates the magnitude of the acceleration correctly
• Correctly applies a timeout between shake events

Here is such a solution:

// variables for shake detection
private static final float SHAKE_THRESHOLD = 3.25f; // m/S**2
private static final int MIN_TIME_BETWEEN_SHAKES_MILLISECS = 1000;
private long mLastShakeTime;
private SensorManager mSensorMgr;

To initialize the timer:

// Get a sensor manager to listen for shakes
mSensorMgr = (SensorManager) getSystemService(SENSOR_SERVICE);

// Listen for shakes
Sensor accelerometer = mSensorMgr.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
if (accelerometer != null) {
    mSensorMgr.registerListener(this, accelerometer, SensorManager.SENSOR_DELAY_NORMAL);
}

SensorEventListener methods to override:

@Override
public void onSensorChanged(SensorEvent event) {
    if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER) {
        long curTime = System.currentTimeMillis();
        if ((curTime - mLastShakeTime) > MIN_TIME_BETWEEN_SHAKES_MILLISECS) {

            float x = event.values[0];
            float y = event.values[1];
            float z = event.values[2];

            double acceleration = Math.sqrt(Math.pow(x, 2) +
                    Math.pow(y, 2) +
                    Math.pow(z, 2)) - SensorManager.GRAVITY_EARTH;
            Log.d(APP_NAME, "Acceleration is " + acceleration + "m/s^2");

            if (acceleration > SHAKE_THRESHOLD) {
                mLastShakeTime = curTime;
                Log.d(APP_NAME, "Shake, Rattle, and Roll");
            }
        }
    }
}

@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
    // Ignore
}

When you are all done

// Stop listening for shakes
mSensorMgr.unregisterListener(this);

itertools.groupby is a tool for grouping items.

From the docs, we glean further what it might do:

# [k for k, g in groupby('AAAABBBCCDAABBB')] --> A B C D A B

# [list(g) for k, g in groupby('AAAABBBCCD')] --> AAAA BBB CC D

groupby objects yield key-group pairs where the group is a generator.

Features

• A. Group consecutive items together
• B. Group all occurrences of an item, given a sorted iterable
• C. Specify how to group items with a key function ^*

Comparisons

# Define a printer for comparing outputs
>>> def print_groupby(iterable, keyfunc=None):
...    for k, g in it.groupby(iterable, keyfunc):
...        print("key: '{}'--> group: {}".format(k, list(g)))

# Feature A: group consecutive occurrences
>>> print_groupby("BCAACACAADBBB")
key: 'B'--> group: ['B']
key: 'C'--> group: ['C']
key: 'A'--> group: ['A', 'A']
key: 'C'--> group: ['C']
key: 'A'--> group: ['A']
key: 'C'--> group: ['C']
key: 'A'--> group: ['A', 'A']
key: 'D'--> group: ['D']
key: 'B'--> group: ['B', 'B', 'B']

# Feature B: group all occurrences
>>> print_groupby(sorted("BCAACACAADBBB"))
key: 'A'--> group: ['A', 'A', 'A', 'A', 'A']
key: 'B'--> group: ['B', 'B', 'B', 'B']
key: 'C'--> group: ['C', 'C', 'C']
key: 'D'--> group: ['D']

# Feature C: group by a key function
>>> # islower = lambda s: s.islower()                      # equivalent
>>> def islower(s):
...     """Return True if a string is lowercase, else False."""   
...     return s.islower()
>>> print_groupby(sorted("bCAaCacAADBbB"), keyfunc=islower)
key: 'False'--> group: ['A', 'A', 'A', 'B', 'B', 'C', 'C', 'D']
key: 'True'--> group: ['a', 'a', 'b', 'b', 'c']

Uses

• Anagrams (see notebook)
• Binning
• Group odd and even numbers
• Group a list by values
• Remove duplicate elements
• Find indices of repeated elements in an array
• Split an array into n-sized chunks
• Find corresponding elements between two lists
• Compression algorithm (see notebook)/Run Length Encoding
• Grouping letters by length, key function (see notebook)
• Consecutive values over a threshold (see notebook)
• Find ranges of numbers in a list or continuous items (see docs)
• Find all related longest sequences
• Take consecutive sequences that meet a condition (see related post)

Note: Several of the latter examples derive from Víctor Terrón's PyCon (talk) (Spanish), "Kung Fu at Dawn with Itertools". See also the groupby source code written in C.

^{* A function where all items are passed through and compared, influencing the result. Other objects with key functions include sorted(), max() and min().}

Response

# OP: Yes, you can use `groupby`, e.g. 
[do_something(list(g)) for _, g in groupby(lxml_elements, criteria_func)]

By referring to https://jwt.io/ you can find jwt implementations in many languages including java. Also the site provide some comparison between these implementation (the algorithms they support and ....).

For java these are mentioned libraries:

You can save your array as a json.
there is documentation for json data type: https://dev.mysql.com/doc/refman/5.7/en/json.html

If you want to just shift everything down you can use:

Rows(1).Insert shift:=xlShiftDown

Similarly to shift everything over:

Columns(1).Insert shift:=xlShiftRight

Here is a working example of extracting text from a PDF file using the current version of PDFMiner(September 2016)

from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage
from io import StringIO

def convert_pdf_to_txt(path):
    rsrcmgr = PDFResourceManager()
    retstr = StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
    fp = open(path, 'rb')
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    password = ""
    maxpages = 0
    caching = True
    pagenos=set()

    for page in PDFPage.get_pages(fp, pagenos, maxpages=maxpages, password=password,caching=caching, check_extractable=True):
        interpreter.process_page(page)

    text = retstr.getvalue()

    fp.close()
    device.close()
    retstr.close()
    return text

PDFMiner's structure changed recently, so this should work for extracting text from the PDF files.

Edit : Still working as of the June 7th of 2018. Verified in Python Version 3.x

Edit: The solution works with Python 3.7 at October 3, 2019. I used the Python library pdfminer.six, released on November 2018.

Since Stack Overflow’s broken RSS just resurrected this question for me, here’s my almost-general solution: JAValueToString

This lets you write JA_DUMP(cgPoint) and get cgPoint = {0, 0} logged.

If you want a DOM-like API - that is, one where the XML parser turns the document into a tree of Element and Attribute nodes - then there are at least four to choose from: DOM itself, JDOM, DOM4J, and XOM. The only possible reason to use DOM is because it's perceived as a standard and is supplied in the JDK: in all other respects, the others are all superior. My own preference, for its combination of simplicity, power, and performance, is XOM.

And of course, there are other styles of processing: low-level parser interfaces (SAX and StAX), data-object binding interfaces (JAXB), and high-level declarative languages (XSLT, XQuery, XPath). Which is best for you depends on your project requirements and your personal taste.

Your hyphen in your ELSE statement isn't accepted in the column which is being defined under the datetime data type. You could either:

a) Wrap a CAST around your [stat] field to convert it to a varchar representation of a date

b) Use a datetime like 9999-12-31 for your ELSE value.

I tried all of the other suggestions in this thread and nothing worked - however I found this thread from the Jetbrains site and their solution did work for me. I hope it helps some of you as well. Specifically this suggestion worked:

• Close the IDE
• Delete the /Users/yourname/Library/Caches/IntelliJIdeaXXX/ directory (whatever your version is)
• Start IDE and re-import project from scratch as Maven project

Worked like a charm for me, good luck! :wave:

btw I'm using IntelliJ IDEA Ultimate 2020.2 on a Mac.

Command:

$ git mv oldFolderName newFolderName

It usually works fine.

Error "bad source ..." typically indicates that after last commit there were some renames in the source directory and hence git mv cannot find the expected file.

The solution is simple - just commit before applying git mv.

According to the properties of DFS and BFS. For example,when we want to find the shortest path. we usually use bfs,it can guarantee the 'shortest'. but dfs only can guarantee that we can come from this point can achieve that point ,can not guarantee the 'shortest'.

According to http://developer.android.com/guide/topics/ui/actionbar.html

The ActionBar APIs were first added in Android 3.0 (API level 11) but they are also available in the Support Library for compatibility with Android 2.1 (API level 7) and above.

In short, that auto-generated project you're seeing modularizes the process of adding the ActionBar to APIs 7-10.

See http://hmkcode.com/add-actionbar-to-android-2-3-x/ for a simplified explanation and tutorial on the topic.

The PDB file is a Visual Studio specific file that has the debugging symbols for your project. You can ignore those messages, unless you're hoping to step into the code for those dlls with the debugger (which is doubtful, as those are system dlls). In other words, you can and should ignore them, as you won't have the PDB files for any of those dlls (by default at least, it turns out you can actually obtain them when debugging via the Microsoft Symbol Server). All it means is that when you set a breakpoint and are stepping through the code, you won't be able to step into any of those dlls (which you wouldn't want to do anyways).

Just for completeness, here's the official PDB description from MSDN:

A program database (PDB) file holds debugging and project state information that allows incremental linking of a Debug configuration of your program. A PDB file is created when you compile a C/C++ program with /ZI or /Zi

Also for future reference, if you want to have PDB files for your own code, you would would have to build your project with either the /ZI or /Zi options enabled (you can set them via project properties --> C/C++ --> General, then set the field for "Debug Information Format"). Not relevant to your situation, but I figured it might be useful in the future

var link = $("#me").closest(":has(h3 span b)").find('span b').text();

If you are asking if you can pair two devices without the user EVER approving the pairing, no it cannot be done, it is a security feature. If you are paired over Bluetooth there is no need to exchange data over NFC, just exchange data over the Bluetooth link.

I don't think you can circumvent Bluetooth security by passing an authentication packet over NFC, but I could be wrong.

It means parent/child

example:

html>body

that's saying that body is a child of html

Combining some answers from this post and also from here, and after some personal research, for NodeJS with typescript I managed to accomplish this by using firebase-admin:

import * as admin from 'firebase-admin';
const getFileNames = (folderName: any) => {
  admin.storage().bucket().getFiles(autoPaginate: false).then(([files]: any) => {
    const fileNames = files.map((file: any) => file.name);
    return fileNames;
  })
 }

In my case I also needed to get all the files from a specific folder from firebase storage. According to google storage the folders don't exists but are rather a naming conventions. Anyway I managed to to this by adding { prefix: ${folderName}, autoPaginate: false } the the getFiles function so:

getFiles({ prefix: `${folderName}`, autoPaginate: false })

There are a few ways to use log4net. I found it is useful while I was searching for a solution. The solution is described here: https://www.hemelix.com/log4net/

"The problem is that i cant find a way to set a fixed number of rows"

You don't need to set the number of rows. Use a TableModel. A DefaultTableModel in particular.

String col[] = {"Pos","Team","P", "W", "L", "D", "MP", "GF", "GA", "GD"};

DefaultTableModel tableModel = new DefaultTableModel(col, 0);
                                            // The 0 argument is number rows.

JTable table = new JTable(tableModel);

Then you can add rows to the tableModel with an Object[]

Object[] objs = {1, "Arsenal", 35, 11, 2, 2, 15, 30, 11, 19};

tableModel.addRow(objs);

You can loop to add your Object[] arrays.

Note: JTable does not currently allow instantiation with the input data as an ArrayList. It must be a Vector or an array.

See JTable and DefaultTableModel. Also, How to Use JTable tutorial

"I created an arrayList from it and I somehow can't find a way to store this information into a JTable."

You can do something like this to add the data

ArrayList<FootballClub> originalLeagueList = new ArrayList<FootballClub>();

originalLeagueList.add(new FootballClub(1, "Arsenal", 35, 11, 2, 2, 15, 30, 11, 19));
originalLeagueList.add(new FootballClub(2, "Liverpool", 30, 9, 3, 3, 15, 34, 18, 16));
originalLeagueList.add(new FootballClub(3, "Chelsea", 30, 9, 2, 2, 15, 30, 11, 19));
originalLeagueList.add(new FootballClub(4, "Man City", 29, 9, 2, 4, 15, 41, 15, 26));
originalLeagueList.add(new FootballClub(5, "Everton", 28, 7, 1, 7, 15, 23, 14, 9));
originalLeagueList.add(new FootballClub(6, "Tottenham", 27, 8, 4, 3, 15, 15, 16, -1));
originalLeagueList.add(new FootballClub(7, "Newcastle", 26, 8, 5, 2, 15, 20, 21, -1));
originalLeagueList.add(new FootballClub(8, "Southampton", 23, 6, 4, 5, 15, 19, 14, 5));

for (int i = 0; i < originalLeagueList.size(); i++){
   int position = originalLeagueList.get(i).getPosition();
   String name = originalLeagueList.get(i).getName();
   int points = originalLeagueList.get(i).getPoinst();
   int wins = originalLeagueList.get(i).getWins();
   int defeats = originalLeagueList.get(i).getDefeats();
   int draws = originalLeagueList.get(i).getDraws();
   int totalMatches = originalLeagueList.get(i).getTotalMathces();
   int goalF = originalLeagueList.get(i).getGoalF();
   int goalA = originalLeagueList.get(i).getGoalA();
   in ttgoalD = originalLeagueList.get(i).getTtgoalD();

   Object[] data = {position, name, points, wins, defeats, draws, 
                               totalMatches, goalF, goalA, ttgoalD};

   tableModel.add(data);

}

You can use trap:

try { block A } catch { block B } finally { block C }

translates to:

(
  set -Ee

  function _finally {

Only today we had an issue where a record failed to be inserted into our Rate table, because one of the columns (GrossRate) is set to Decimal (11,4), and our Product department just got a contract for rooms in some amazing resort in Bora Bora, that sell for several million Pacific Francs per night... something that was never anticpated when the database schema was designed 10 years ago.

You're most likely closing the session inside of the RoleDao. If you close the session then try to access a field on an object that was lazy-loaded, you will get this exception. You should probably open and close the session/transaction in your test.

Here's a self contained Delphi / Pascal version of the function based on Joshua's answer up above. Uses TPoint for VCL screen graphics, but should be easy to adjust as needed.

function DistancePtToSegment( pt, pt1, pt2: TPoint): double;
var
   a, b, c, d: double;
   len_sq: double;
   param: double;
   xx, yy: double;
   dx, dy: double;
begin
   a := pt.x - pt1.x;
   b := pt.y - pt1.y;
   c := pt2.x - pt1.x;
   d := pt2.y - pt1.y;

   len_sq := (c * c) + (d * d);
   param := -1;

   if (len_sq <> 0) then
   begin
      param := ((a * c) + (b * d)) / len_sq;
   end;

   if param < 0 then
   begin
      xx := pt1.x;
      yy := pt1.y;
   end
   else if param > 1 then
   begin
      xx := pt2.x;
      yy := pt2.y;
   end
   else begin
      xx := pt1.x + param * c;
      yy := pt1.y + param * d;
   end;

   dx := pt.x - xx;
   dy := pt.y - yy;
   result := sqrt( (dx * dx) + (dy * dy))
end;

Use double braces {{ or }} so your code becomes:

sb.AppendLine(String.Format("public {0} {1} {{ get; private set; }}", 
prop.Type, prop.Name));

// For prop.Type of "Foo" and prop.Name of "Bar", the result would be:
// public Foo Bar { get; private set; }

This worked fine for me.

The question wasn't specific to Linux/Bash so I thought I would add the Powershell way - which treats wildcards different - you put it in the quotes like so below:

If (Test-Path "./output/test-pdf-docx/Text-Book-Part-I*"){
  Remove-Item -force -v -path ./output/test-pdf-docx/*.pdf
  Remove-Item -force -v -path ./output/test-pdf-docx/*.docx
}

I think this is helpful because the concept of the original question covers "shells" in general not just Bash or Linux, and would apply to Powershell users with the same question too.

Adding my own variation to the mix. I think it's the simplest of the lot and can be useful when efficiency is not a big concern.

find . -type f | grep -o -E '\.[^\.]+$' | sort -u

Since you are conditionally indexing df$est, you also need to conditionally index the replacement vector df$a:

index <- df$b == 0
df$est[index] <- (df$a[index] - 5)/2.533 

Of course, the variable index is just temporary, and I use it to make the code a bit more readible. You can write it in one step:

df$est[df$b == 0] <- (df$a[df$b == 0] - 5)/2.533 

For even better readibility, you can use within:

df <- within(df, est[b==0] <- (a[b==0]-5)/2.533)

The results, regardless of which method you choose:

df
          a b      est
1  11.77000 2 0.000000
2  10.90000 3 0.000000
3  10.32000 2 0.000000
4  10.96000 0 2.352941
5   9.90600 0 1.936834
6  10.70000 0 2.250296
7  11.43000 1 0.000000
8  11.41000 2 0.000000
9  10.48512 4 0.000000
10 11.19000 0 2.443743

As others have pointed out, an alternative solution in your example is to use ifelse.

Trying "docker exec ... < data.sql" in Window PowerShell responses with:

The '<' operator is reserved for future use.

But one can wrap it out with cmd /c to eliminate the issue:

cmd /c "docker exec -i mysql-container mysql -uuser -ppassword name_db < data.sql"

New answer to old question, sorry. I thought I'd add my $.02

The OP asked if the headers were encrypted.

They are: in transit.

They are NOT: when not in transit.

So, your browser's URL (and title, in some cases) can display the querystring (which usually contain the most sensitive details) and some details in the header; the browser knows some header information (content type, unicode, etc); and browser history, password management, favorites/bookmarks, and cached pages will all contain the querystring. Server logs on the remote end can also contain querystring as well as some content details.

Also, the URL isn't always secure: the domain, protocol, and port are visible - otherwise routers don't know where to send your requests.

Also, if you've got an HTTP proxy, the proxy server knows the address, usually they don't know the full querystring.

So if the data is moving, it's generally protected. If it's not in transit, it's not encrypted.

Not to nit pick, but data at the end is also decrypted, and can be parsed, read, saved, forwarded, or discarded at will. And, malware at either end can take snapshots of data entering (or exiting) the SSL protocol - such as (bad) Javascript inside a page inside HTTPS which can surreptitiously make http (or https) calls to logging websites (since access to local harddrive is often restricted and not useful).

Also, cookies are not encrypted under the HTTPS protocol, either. Developers wanting to store sensitive data in cookies (or anywhere else for that matter) need to use their own encryption mechanism.

As to cache, most modern browsers won't cache HTTPS pages, but that fact is not defined by the HTTPS protocol, it is entirely dependent on the developer of a browser to be sure not to cache pages received through HTTPS.

So if you're worried about packet sniffing, you're probably okay. But if you're worried about malware or someone poking through your history, bookmarks, cookies, or cache, you are not out of the water yet.

You can use geom_col() directly. See the differences between geom_bar() and geom_col() in this link https://ggplot2.tidyverse.org/reference/geom_bar.html

geom_bar() makes the height of the bar proportional to the number of cases in each group If you want the heights of the bars to represent values in the data, use geom_col() instead.

ggplot(data_country)+aes(x=country,y = conversion_rate)+geom_col()

In this example, nothing really. The exact param comes into play when you have multiple paths that have similar names:

For example, imagine we had a Users component that displayed a list of users. We also have a CreateUser component that is used to create users. The url for CreateUsers should be nested under Users. So our setup could look something like this:

<Switch>
  <Route path="/users" component={Users} />
  <Route path="/users/create" component={CreateUser} />
</Switch>

Now the problem here, when we go to http://app.com/users the router will go through all of our defined routes and return the FIRST match it finds. So in this case, it would find the Users route first and then return it. All good.

But, if we went to http://app.com/users/create, it would again go through all of our defined routes and return the FIRST match it finds. React router does partial matching, so /users partially matches /users/create, so it would incorrectly return the Users route again!

The exact param disables the partial matching for a route and makes sure that it only returns the route if the path is an EXACT match to the current url.

So in this case, we should add exact to our Users route so that it will only match on /users:

<Switch>
  <Route exact path="/users" component={Users} />
  <Route path="/users/create" component={CreateUser} />
</Switch>

The docs explain exact in detail and give other examples.

While most of the answers here are valid, for me the issue was that I was running long processes as part of npm run start which caused the timeout.

I found the solution here and to summarize it, I just had to move npm run build to a postinstall task.

In other words, I changed this:

"start": "npm run build && node server.js"

to this:

"postinstall": "npm run build",
"start": "node server.js"

Come to think of this, it totally makes sense because this error (which used to appear occasionally) was becoming more and more common as my app kept growing.

In scala implicit works as:

Converter

Parameter value injector

Extension method

There are 3 types of use of Implicit

1. Implicitly type conversion : It converts the error producing assignment into intended type

   val x :String = "1"
   
   val y:Int = x
   

String is not the sub type of Int , so error happens in line 2. To resolve the error the compiler will look for such a method in the scope which has implicit keyword and takes a String as argument and returns an Int .

so

implicit def z(a:String):Int = 2

val x :String = "1"

val y:Int = x // compiler will use z here like val y:Int=z(x)

println(y) // result 2  & no error!

2. Implicitly receiver conversion: We generally by receiver call object's properties, eg. methods or variables . So to call any property by a receiver the property must be the member of that receiver's class/object.

    class Mahadi{
   
    val haveCar:String ="BMW"
   
    }
   

    class Johnny{

    val haveTv:String = "Sony"

    }

   val mahadi = new Mahadi



   mahadi.haveTv // Error happening

Here mahadi.haveTv will produce an error. Because scala compiler will first look for the haveTv property to mahadi receiver. It will not find. Second it will look for a method in scope having implicit keyword which take Mahadi object as argument and returns Johnny object. But it does not have here. So it will create error. But the following is okay.

class Mahadi{

val haveCar:String ="BMW"

}

class Johnny{

val haveTv:String = "Sony"

}

val mahadi = new Mahadi

implicit def z(a:Mahadi):Johnny = new Johnny

mahadi.haveTv // compiler will use z here like new Johnny().haveTv

println(mahadi.haveTv)// result Sony & no error

3. Implicitly parameter injection: If we call a method and do not pass its parameter value, it will cause an error. The scala compiler works like this - first will try to pass value, but it will get no direct value for the parameter.

    def x(a:Int)= a
   
    x // ERROR happening
   

Second if the parameter has any implicit keyword it will look for any val in the scope which have the same type of value. If not get it will cause error.

def x(implicit a:Int)= a

x // error happening here

To slove this problem compiler will look for a implicit val having the type of Int because the parameter a has implicit keyword.

def x(implicit a:Int)=a

implicit val z:Int =10

x // compiler will use implicit like this x(z)
println(x) // will result 10 & no error.

Another example:

def l(implicit b:Int)

def x(implicit a:Int)= l(a)

we can also write it like-

def x(implicit a:Int)= l

Because l has a implicit parameter and in scope of method x's body, there is an implicit local variable(parameters are local variables) a which is the parameter of x, so in the body of x method the method-signature l's implicit argument value is filed by the x method's local implicit variable(parameter) a implicitly.

So

 def x(implicit a:Int)= l

will be in compiler like this

def x(implicit a:Int)= l(a)

Another example:

def c(implicit k:Int):String = k.toString

def x(a:Int => String):String =a

x{
x => c
}

it will cause error, because c in x{x=>c} needs explicitly-value-passing in argument or implicit val in scope.

So we can make the function literal's parameter explicitly implicit when we call the method x

x{
implicit x => c // the compiler will set the parameter of c like this c(x)
}

This has been used in action method of Play-Framework

in view folder of app the template is declared like
@()(implicit requestHreader:RequestHeader)

in controller action is like

def index = Action{
implicit request =>

Ok(views.html.formpage())  

}

if you do not mention request parameter as implicit explicitly then you must have been written-

def index = Action{
request =>

Ok(views.html.formpage()(request))  

}

4. Extension Method

Think, we want to add new method with Integer object. The name of the method will be meterToCm,

> 1 .meterToCm 
res0 100 

to do this we need to create an implicit class within a object/class/trait . This class can not be a case class.

object Extensions{
    
    implicit class MeterToCm(meter:Int){
        
        def  meterToCm={
             meter*100
        }

    }

}

Note the implicit class will only take one constructor parameter.

Now import the implicit class in the scope you are wanting to use

import  Extensions._

2.meterToCm // result 200

The error is explicit, you are trying to link libraries that were compiled with different CPU targets. An executable image can only contain pure x86 (32-bit) or pure x64 (64-bit) code. Mixing is not possible.

You change the target CPU by creating a new configuration for the project, only changing the linker setting isn't enough. Build + Configuration Manager, Active solution platform combo on upper right, choose New and select x64. That creates a new configuration with several modified project settings, most importantly the compiler that will be used.

Beware that prior to VS2010, the 64-bit compilers are not installed by default. If you don't see x64 in the platform combo then you'll need to re-run setup.exe and turn on the option to install the 64-bit compilers. Then also re-run any service pack installer you may have applied.

A possible approach with less pain points is to use the 32-bit version of the library.

What helped me was to add an event directly to this page and click around for myself! Open up your console in developer tools/Firebug etc and paste this:

document.addEventListener('click', function(e) {_x000D_
  console.log(_x000D_
    'page: ' + e.pageX + ',' + e.pageY,_x000D_
    'client: ' + e.clientX + ',' + e.clientY,_x000D_
    'screen: ' + e.screenX + ',' + e.screenY)_x000D_
}, false);

Click anywhere

With this snippet, you can track your click position as you scroll, move the browser window, etc.

Notice that pageX/Y and clientX/Y are the same when you're scrolled all the way to the top!

This might be a faster way:

DECLARE @action char(1)

IF COLUMNS_UPDATED() > 0 -- insert or update
BEGIN
    IF EXISTS (SELECT * FROM DELETED) -- update
        SET @action = 'U'
    ELSE
        SET @action = 'I'
    END
ELSE -- delete
    SET @action = 'D'

Cong Ma does a good job of explaining what __getitem__ is used for - but I want to give you an example which might be useful. Imagine a class which models a building. Within the data for the building it includes a number of attributes, including descriptions of the companies that occupy each floor :

Without using __getitem__ we would have a class like this :

class Building(object):
     def __init__(self, floors):
         self._floors = [None]*floors
     def occupy(self, floor_number, data):
          self._floors[floor_number] = data
     def get_floor_data(self, floor_number):
          return self._floors[floor_number]

building1 = Building(4) # Construct a building with 4 floors
building1.occupy(0, 'Reception')
building1.occupy(1, 'ABC Corp')
building1.occupy(2, 'DEF Inc')
print( building1.get_floor_data(2) )

We could however use __getitem__ (and its counterpart __setitem__) to make the usage of the Building class 'nicer'.

class Building(object):
     def __init__(self, floors):
         self._floors = [None]*floors
     def __setitem__(self, floor_number, data):
          self._floors[floor_number] = data
     def __getitem__(self, floor_number):
          return self._floors[floor_number]

building1 = Building(4) # Construct a building with 4 floors
building1[0] = 'Reception'
building1[1] = 'ABC Corp'
building1[2] = 'DEF Inc'
print( building1[2] )

Whether you use __setitem__ like this really depends on how you plan to abstract your data - in this case we have decided to treat a building as a container of floors (and you could also implement an iterator for the Building, and maybe even the ability to slice - i.e. get more than one floor's data at a time - it depends on what you need.

new Buffer(number)            // Old
Buffer.alloc(number)          // New

new Buffer(string)            // Old
Buffer.from(string)           // New

new Buffer(string, encoding)  // Old
Buffer.from(string, encoding) // New

new Buffer(...arguments)      // Old
Buffer.from(...arguments)     // New

Note that Buffer.alloc() is also faster on the current Node.js versions than new Buffer(size).fill(0), which is what you would otherwise need to ensure zero-filling.

in your question, both buffer and byteArray seem to be byte[]. So:

ImageElement image = ImageElement.FromBinary(buffer);

Update

Ignore this answer. Not that it doesn't work. But there are better methods available. Moreover, Android emphatically discourage direct communication between fragments. See official doc. Thanks user @Wahib Ul Haq for the tip.

Original Answer

Well, you can create a private variable and setter in Fragment B, and set the value from Fragment A itself,

FragmentB.java

private String inputString;
....
....

public void setInputString(String string){
   inputString = string;
}

FragmentA.java

//go to fragment B

FragmentB frag  = new FragmentB();
frag.setInputString(YOUR_STRING);
//create your fragment transaction object, set animation etc
fragTrans.replace(ITS_ARGUMENTS)

Or you can use Activity as you suggested in question..

It could be some other line as well. PHP is not always that exact.

Probably you are just missing a semicolon on previous line.

How to reproduce this error, put this in a file called a.php:

<?php
  $a = 5
  $b = 7;        // Error happens here.
  print $b;
?>

Run it:

eric@dev ~ $ php a.php

PHP Parse error:  syntax error, unexpected T_VARIABLE in
/home/el/code/a.php on line 3

Explanation:

The PHP parser converts your program to a series of tokens. A T_VARIABLE is a Token of type VARIABLE. When the parser processes tokens, it tries to make sense of them, and throws errors if it receives a variable where none is allowed.

In the simple case above with variable $b, the parser tried to process this:

$a = 5 $b = 7;

The PHP parser looks at the $b after the 5 and says "that is unexpected".

As you say, local variables and references are stored on the stack. When a method returns, the stack pointer is simply moved back to where it was before the method started, that is, all local data is "removed from the stack". Therefore, there is no garbage collection needed on the stack, that only happens in the heap.

To answer your specific questions:

• See this question on how to increase the stack size.
• You can limit the stack growth by:
  • grouping many local variables in an object: that object will be stored in the heap and only the reference is stored on the stack
  • limit the number of nested function calls (typically by not using recursion)
• For windows, the default stack size is 320k for 32bit and 1024k for 64bit, see this link.

It seems as of now, the only solution is still to install SublimeREPL.

To extend on Raghav's answer, it can be quite annoying to have to go into the Tools->SublimeREPL->Python->Run command every time you want to run a script with input, so I devised a quick key binding that may be handy:

To enable it, go to Preferences->Key Bindings - User, and copy this in there:

[
    {"keys":["ctrl+r"] , 
    "caption": "SublimeREPL: Python - RUN current file",
    "command": "run_existing_window_command", 
    "args":
        {
            "id": "repl_python_run",
            "file": "config/Python/Main.sublime-menu"
        }
    },
]

Naturally, you would just have to change the "keys" argument to change the shortcut to whatever you'd like.

You should inject $document in your controller, and use it instead of original document object.

var myElement = angular.element($document[0].querySelector('#MyID'))

If you don't need the jquery style element wrap, $document[0].querySelector('#MyID') will give you the DOM object.
