Programs & Examples On #Feature extraction

Try something like this:

int main()
{
    printf("%x %x %x %x %x %x %x %x\n",
        0xC0, 0xC0, 0x61, 0x62, 0x63, 0x31, 0x32, 0x33);
}

Which produces this:

$ ./foo 
c0 c0 61 62 63 31 32 33

To set a session-timeout that never expires is not desirable because you would be reliable on the user to push the logout-button every time he's finished to prevent your server of too much load (depending on the amount of users and the hardware). Additionaly there are some security issues you might run into you would rather avoid.

The reason why the session gets invalidated while the server is still working on a task is because there is no communication between client-side (users browser) and server-side through e.g. a http-request. Therefore the server can't know about the users state, thinks he's idling and invalidates the session after the time set in your web.xml.

To get around this you have several possibilities:

• You could ping your backend while the task is running to touch the session and prevent it from being expired
• increase the <session-timeout> inside the server but I wouldn't recommend this
• run your task in a dedicated thread which touches (extends) the session while working or notifies the user when the thread has finished

There was a similar question asked, maybe you can adapt parts of this solution in your project. Have a look at this.

Hope this helps, have Fun!

This answer extends Jonathan S's excellent solution:

You can use the following method to extract links from the text:

private static ArrayList<String> getLinksFromText(String text) {
        ArrayList links = new ArrayList();

        String regex = "\(?\b((http|https)://www[.])[-A-Za-z0-9+&@#/%?=~_()|!:,.;]*[-A-Za-z0-9+&@#/%=~_()|]";
        Pattern p = Pattern.compile(regex);
        Matcher m = p.matcher(text);
        while (m.find()) {
            String urlStr = m.group();
            if (urlStr.startsWith("(") && urlStr.endsWith(")")) {
                urlStr = urlStr.substring(1, urlStr.length() - 1);
            }
            links.add(urlStr);
        }
        return links;
    }

This can be used to remove one of the parameters in the clickify() method:

public static void clickify(TextView view,
                                final ClickSpan.OnClickListener listener) {

        CharSequence text = view.getText();
        String string = text.toString();


        ArrayList<String> linksInText = getLinksFromText(string);
        if (linksInText.isEmpty()){
            return;
        }


        String clickableText = linksInText.get(0);
        ClickSpan span = new ClickSpan(listener,clickableText);

        int start = string.indexOf(clickableText);
        int end = start + clickableText.length();
        if (start == -1) return;

        if (text instanceof Spannable) {
            ((Spannable) text).setSpan(span, start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        } else {
            SpannableString s = SpannableString.valueOf(text);
            s.setSpan(span, start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
            view.setText(s);
        }

        MovementMethod m = view.getMovementMethod();
        if ((m == null) || !(m instanceof LinkMovementMethod)) {
            view.setMovementMethod(LinkMovementMethod.getInstance());
        }
    }

A few changes to the ClickSpan:

public static class ClickSpan extends ClickableSpan {

        private String mClickableText;
        private OnClickListener mListener;

        public ClickSpan(OnClickListener listener, String clickableText) {
            mListener = listener;
            mClickableText = clickableText;
        }

        @Override
        public void onClick(View widget) {
            if (mListener != null) mListener.onClick(mClickableText);
        }

        public interface OnClickListener {
            void onClick(String clickableText);
        }
    }

Now you can simply set the text on the TextView and then add a listener to it:

TextViewUtils.clickify(textWithLink,new TextUtils.ClickSpan.OnClickListener(){

@Override
public void onClick(String clickableText){
  //action...
}

});

you can't. foo-bar is not an identifier. rename the file to foo_bar.py

Edit: If import is not your goal (as in: you don't care what happens with sys.modules, you don't need it to import itself), just getting all of the file's globals into your own scope, you can use execfile

# contents of foo-bar.py
baz = 'quux'

>>> execfile('foo-bar.py')
>>> baz
'quux'
>>> 

HEAD is not the latest revision, it's the current revision. Usually, it's the latest revision of the current branch, but it doesn't have to be.

master is a name commonly given to the main branch, but it could be called anything else (or there could be no main branch).

origin is a name commonly given to the main remote. remote is another repository that you can pull from and push to. Usually it's on some server, like github.

First, shoutout to ashraf aaref, who's answer I would like to expand a little.

As MDN Web Docs suggest, using RadioNodeList is the preferred way to go:

// Get the form
const form = document.forms[0];

// Get the form's radio buttons
const radios = form.elements['color'];

// You can also easily get the selected value
console.log(radios.value);

// Set the "red" option as the value, i.e. select it
radios.value = 'red';

One might however also select the form via querySelector, which works fine too:

const form = document.querySelector('form[name="somename"]')

However, selecting the radios directly will not work, because it returns a simple NodeList.

document.querySelectorAll('input[name="color"]')
// Returns: NodeList [ input, input ]

While selecting the form first returns a RadioNodeList

document.forms[0].elements['color']
// document.forms[0].color # Shortcut variant
// document.forms[0].elements['complex[naming]'] # Note: shortcuts do not work well with complex field names, thus `elements` for a more programmatic aproach
// Returns: RadioNodeList { 0: input, 1: input, value: "red", length: 2 }

This is why you have to select the form first and then call the elements Method. Aside from all the input Nodes, the RadioNodeList also includes a property value, which enables this simple manipulation.

Coroutines (AKA Stackless threads) in C. :) It's Evil trickery.

#define crBegin static int state=0; switch(state) { case 0:
#define crReturn(i,x) do { state=i; return x; case i:; } while (0)
#define crFinish }
int function(void) {
    static int i;
    crBegin;
    for (i = 0; i < 10; i++)
        crReturn(1, i);
    crFinish;
}

int decompressor(void) {
    static int c, len;
    crBegin;
    while (1) {
        c = getchar();
        if (c == EOF)
            break;
        if (c == 0xFF) {
            len = getchar();
            c = getchar();
            while (len--)
            crReturn(c);
        } else
        crReturn(c);
    }
    crReturn(EOF);
    crFinish;
}


void parser(int c) {
    crBegin;
    while (1) {
        /* first char already in c */
        if (c == EOF)
            break;
        if (isalpha(c)) {
            do {
                add_to_token(c);
        crReturn( );
            } while (isalpha(c));
            got_token(WORD);
        }
        add_to_token(c);
        got_token(PUNCT);
    crReturn( );
    }
    crFinish;
}

You can use sort() function. sort() exists in algorithm header file

        #include<bits/stdc++.h>
        using namespace std;


        int main()
        {
            ios::sync_with_stdio(false);
            string str = "sharlock";

            sort(str.begin(), str.end());
            cout<<str<<endl;

            return 0;
        }

Output:

achklors

The MediaStore API is probably throwing away the alpha channel (i.e. decoding to RGB565). If you have a file path, just use BitmapFactory directly, but tell it to use a format that preserves alpha:

BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap bitmap = BitmapFactory.decodeFile(photoPath, options);
selected_photo.setImageBitmap(bitmap);

I was able to get a great solution to this problem with iScroll, with the feel of momentum scrolling and everything https://github.com/cubiq/iscroll The github doc is great, and I mostly followed it. Here's the details of my implementation.

HTML: I wrapped the scrollable area of my content in some divs that iScroll can use:

<div id="wrapper">
  <div id="scroller">
    ... my scrollable content
  </div>
</div>

CSS: I used the Modernizr class for "touch" to target my style changes only to touch devices (because I only instantiated iScroll on touch).

.touch #wrapper {
  position: absolute;
  z-index: 1;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  overflow: hidden;
}
.touch #scroller {
  position: absolute;
  z-index: 1;
  width: 100%;
}

JS: I included iscroll-probe.js from the iScroll download, and then initialized the scroller as below, where updatePosition is my function that reacts to the new scroll position.

# coffeescript
if Modernizr.touch
  myScroller = new IScroll('#wrapper', probeType: 3)
  myScroller.on 'scroll', updatePosition
  myScroller.on 'scrollEnd', updatePosition

You have to use myScroller to get the current position now, instead of looking at the scroll offset. Here is a function taken from http://markdalgleish.com/presentations/embracingtouch/ (a super helpful article, but a little out of date now)

function getScroll(elem, iscroll) {   
  var x, y;

  if (Modernizr.touch && iscroll) {
    x = iscroll.x * -1;
    y = iscroll.y * -1;   
  } else {
    x = elem.scrollTop;
    y = elem.scrollLeft;   
  }

  return {x: x, y: y}; 
}

The only other gotcha was occasionally I would lose part of my page that I was trying to scroll to, and it would refuse to scroll. I had to add in some calls to myScroller.refresh() whenever I changed the contents of the #wrapper, and that solved the problem.

EDIT: Another gotcha was that iScroll eats all the "click" events. I turned on the option to have iScroll emit a "tap" event and handled those instead of "click" events. Thankfully I didn't need much clicking in the scroll area, so this wasn't a big deal.

public static Bitmap createSingleImageFromMultipleImages(Bitmap firstImage, Bitmap secondImage, ImageView secondImageView){

    Bitmap result = Bitmap.createBitmap(firstImage.getWidth(), firstImage.getHeight(), firstImage.getConfig());
    Canvas canvas = new Canvas(result);
    canvas.drawBitmap(firstImage, 0f, 0f, null);
    canvas.drawBitmap(secondImage, secondImageView.getX(), secondImageView.getY(), null);

    return result;
}

You should actually fix your database schema so that you have three tables:

shirt: shirt_id, shirt_name
color: color_id, color_name
shirtcolor: shirt_id, color_id

Then if you want to find all of the shirts that are red, you'd do a query like:

SELECT *
FROM shirt, color
WHERE color.color_name = 'red'
  AND shirt.shirt_id = shirtcolor.shirt_id
  AND color.color_id = shirtcolor.color_id

A quick one-liner.

list_a = [5,4,3,2,1]
list_b = [1,1.5,1.75,2,3,3.5,3.75,4,5]

Say you want list a to match list b.

orderedList =  sorted(list_a, key=lambda x: list_b.index(x))

This is helpful when needing to order a smaller list to values in larger. Assuming that the larger list contains all values in the smaller list, it can be done.

because:

Static : as we can't have objects of interfaces so we should avoid using Object level member variables and should use class level variables i.e. static.

Final : so that we should not have ambiguous values for the variables(Diamond problem - Multiple Inheritance).

And as per the documentation interface is a contract and not an implementation.

mvn clean package -DpropEnv=PROD

Then using like this in POM.xml

<properties>
    <myproperty>${propEnv}</myproperty>
</properties>

you can try

"str".charCodeAt(0)

this is your html code where you are calling function to convert 24 hour time format to 12 hour with am/pm

<pre id="tests" onClick="tConvert('18:00:00')">_x000D_
  test on click 18:00:00_x000D_
</pre>_x000D_
<span id="rzlt"></span>

now in js code write this tConvert function as it is

 function tConvert (time)_x000D_
  {_x000D_
     _x000D_
   // Check correct time format and split into components_x000D_
   time = time.toString ().match (/^([01]\d|2[0-3])(:)([0-5]\d)(:[0-5]\d)?$/) || [time];_x000D_
_x000D_
    if (time.length > 1) _x000D_
    { // If time format correct_x000D_
        _x000D_
      time = time.slice (1);  // Remove full string match value_x000D_
      time[5] = +time[0] < 12 ? 'AM' : 'PM'; // Set AM/PM_x000D_
      time[0] = +time[0] % 12 || 12; // Adjust hours_x000D_
    }_x000D_
    //return time; // return adjusted time or original string_x000D_
      var tel = document.getElementById ('rzlt');_x000D_
      _x000D_
      tel.innerHTML= time.join ('');_x000D_
  }

It will show missing package.

Install missing package and again run below command to make sure if nothing is missed.

Python manage.py makemigrations

It will resolve your issue.

I use the header(name, value) method and give the return to webResource var:

Client client = Client.create();
WebResource webResource = client.resource("uri");

MultivaluedMap<String, String> queryParams = new MultivaluedMapImpl();
queryParams.add("json", js); //set parametes for request

appKey = "Bearer " + appKey; // appKey is unique number

//Get response from RESTful Server get(ClientResponse.class);
ClientResponse response = webResource.queryParams(queryParams)
    .header("Content-Type", "application/json;charset=UTF-8")
    .header("Authorization", appKey)
    .get(ClientResponse.class);

String jsonStr = response.getEntity(String.class);

On windows you can use Drip.exe to find memory leaks or check if your free mem routine works.

It's really simple, just enter a website URL and you will see the memory consumption of the integrated IE renderer. Then hit refresh, if the memory increases, you found a memory leak somewhere on the webpage. But this is also very useful to see if routines for freeing memory work for IE.

Ripgrep, which is a fast alternative to grep, has just introduced the --count-matches flag allowing counting each match in version 0.9 (I'm using the above example to stay consistent):

> echo afoobarfoobar | rg --count foo
1
> echo afoobarfoobar | rg --count-matches foo
2

As asked by OP, ripgrep allows for regex pattern as well (--regexp <PATTERN>). Also it can print each (line) match on a separate line:

> echo -e "line1foo\nline2afoobarfoobar" | rg foo
line1foo
line2afoobarfoobar

I have just copied UUID toString() method and just updated it to remove "-" from it. It will be much more faster and straight forward than any other solution

public String generateUUIDString(UUID uuid) {
    return (digits(uuid.getMostSignificantBits() >> 32, 8) +
            digits(uuid.getMostSignificantBits() >> 16, 4) +
            digits(uuid.getMostSignificantBits(), 4) +
            digits(uuid.getLeastSignificantBits() >> 48, 4) +
            digits(uuid.getLeastSignificantBits(), 12));
}

/** Returns val represented by the specified number of hex digits. */
private String digits(long val, int digits) {
    long hi = 1L << (digits * 4);
    return Long.toHexString(hi | (val & (hi - 1))).substring(1);
}

Usage:

generateUUIDString(UUID.randomUUID())

Another implementation using reflection

public String generateString(UUID uuid) throws NoSuchMethodException, InvocationTargetException, IllegalAccessException {

    if (uuid == null) {
        return "";
    }

    Method digits = UUID.class.getDeclaredMethod("digits", long.class, int.class);
    digits.setAccessible(true);

    return ( (String) digits.invoke(uuid, uuid.getMostSignificantBits() >> 32, 8) +
            digits.invoke(uuid, uuid.getMostSignificantBits() >> 16, 4) +
            digits.invoke(uuid, uuid.getMostSignificantBits(), 4) +
            digits.invoke(uuid, uuid.getLeastSignificantBits() >> 48, 4) +
            digits.invoke(uuid, uuid.getLeastSignificantBits(), 12));

}

to insert into DropDownList:

DropDownList.Items.Insert(0, new ListItem("-- Select item --", "0"));

and to remove item from DropDownList:

DropDownList.Items.Remove(new ListItem("-- Select item --", "0"));

I think these are two really different cases. In the first case memory is allocated and initialized in compile-time. In the second - in runtime.

The language used by Facebook is PHP.

Also, do any other social networking sites use the same language?

The other one I know of is friendster.

1. The reason this is failing is because (Python 3) input returns a string. To convert it to an integer, use int(some_string).

2. You do not typically keep track of indices manually in Python. A better way to implement such a function would be

   def cat_n_times(s, n):
       for i in range(n):
           print(s) 
   
   text = input("What would you like the computer to repeat back to you: ")
   num = int(input("How many times: ")) # Convert to an int immediately.
   
   cat_n_times(text, num)
   

3. I changed your API above a bit. It seems to me that n should be the number of times and s should be the string.

Regarding David Elizondo's answer, this can give false positives. It also does not give zeroes where the values don't match.

Code

DECLARE @t1 TABLE (
    ColID   int     IDENTITY,
    Col2    int
)

DECLARE @t2 TABLE (
    ColID   int     IDENTITY,
    Col2    int
)

INSERT INTO @t1 (Col2) VALUES (123)
INSERT INTO @t1 (Col2) VALUES (234)
INSERT INTO @t1 (Col2) VALUES (456)
INSERT INTO @t1 (Col2) VALUES (1)

INSERT INTO @t2 (Col2) VALUES (123)
INSERT INTO @t2 (Col2) VALUES (345)
INSERT INTO @t2 (Col2) VALUES (456)
INSERT INTO @t2 (Col2) VALUES (2)

SELECT
    t1.Col2 AS t1Col2,
    t2.Col2 AS t2Col2,
    ISNULL(NULLIF(t1.Col2, t2.Col2), 1) AS MyDesiredResult
FROM @t1 AS t1
JOIN @t2 AS t2 ON t1.ColID = t2.ColID

Results

     t1Col2      t2Col2 MyDesiredResult

        234         345             234 <- Not a zero
        456         456               1
          1           2               1 <- Not a match

Let's use some java 8 feature:

IntStream.iterate(10, x -> x + 10).limit(5)
  .forEach(System.out::println);

If you need to store the numbers you can collect them into a collection eg:

List numbers = IntStream.iterate(10, x -> x + 10).limit(5)
  .boxed()
  .collect(Collectors.toList());

And some delay added:

IntStream.iterate(10, x -> x + 10).limit(5)
  .forEach(x -> {
    System.out.println(x);
    try {
      Thread.sleep(2000);
    } catch (InterruptedException e) {
      // Do something with the exception
    }  
  });

The default vector constructor will create an empty vector. As such, you should be able to write:

struct user r = { string(), vector<unsigned char>() };

Note, I've also used the default string constructor instead of "".

You might want to consider making user a class and adding a default constructor that does this for you:

class User {
  User() {}
  string username;
  vector<unsigned char> password;
};

Then just writing:

User r;

Will result in a correctly initialized user.

You should delete old child items thisParent.ChildItems one by one manually. Entity Framework doesn't do that for you. It finally cannot decide what you want to do with the old child items - if you want to throw them away or if you want to keep and assign them to other parent entities. You must tell Entity Framework your decision. But one of these two decisions you HAVE to make since the child entities cannot live alone without a reference to any parent in the database (due to the foreign key constraint). That's basically what the exception says.

Edit

What I would do if child items could be added, updated and deleted:

public void UpdateEntity(ParentItem parent)
{
    // Load original parent including the child item collection
    var originalParent = _dbContext.ParentItems
        .Where(p => p.ID == parent.ID)
        .Include(p => p.ChildItems)
        .SingleOrDefault();
    // We assume that the parent is still in the DB and don't check for null

    // Update scalar properties of parent,
    // can be omitted if we don't expect changes of the scalar properties
    var parentEntry = _dbContext.Entry(originalParent);
    parentEntry.CurrentValues.SetValues(parent);

    foreach (var childItem in parent.ChildItems)
    {
        var originalChildItem = originalParent.ChildItems
            .Where(c => c.ID == childItem.ID && c.ID != 0)
            .SingleOrDefault();
        // Is original child item with same ID in DB?
        if (originalChildItem != null)
        {
            // Yes -> Update scalar properties of child item
            var childEntry = _dbContext.Entry(originalChildItem);
            childEntry.CurrentValues.SetValues(childItem);
        }
        else
        {
            // No -> It's a new child item -> Insert
            childItem.ID = 0;
            originalParent.ChildItems.Add(childItem);
        }
    }

    // Don't consider the child items we have just added above.
    // (We need to make a copy of the list by using .ToList() because
    // _dbContext.ChildItems.Remove in this loop does not only delete
    // from the context but also from the child collection. Without making
    // the copy we would modify the collection we are just interating
    // through - which is forbidden and would lead to an exception.)
    foreach (var originalChildItem in
                 originalParent.ChildItems.Where(c => c.ID != 0).ToList())
    {
        // Are there child items in the DB which are NOT in the
        // new child item collection anymore?
        if (!parent.ChildItems.Any(c => c.ID == originalChildItem.ID))
            // Yes -> It's a deleted child item -> Delete
            _dbContext.ChildItems.Remove(originalChildItem);
    }

    _dbContext.SaveChanges();
}

Note: This is not tested. It's assuming that the child item collection is of type ICollection. (I usually have IList and then the code looks a bit different.) I've also stripped away all repository abstractions to keep it simple.

I don't know if that is a good solution, but I believe that some kind of hard work along these lines must be done to take care of all kinds of changes in the navigation collection. I would also be happy to see an easier way of doing it.

To provide POST parameter send your parameter as JSONObject in to the JsonObjectRequest constructor. 3rd parameter accepts a JSONObject that is used in Request body.

JSONObject paramJson = new JSONObject();

paramJson.put("key1", "value1");
paramJson.put("key2", "value2");


JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST,url,paramJson,
    new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {

        }
    },
    new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {

        }
    });
requestQueue.add(jsonObjectRequest);

The easiest way is probably to use xvfb-run:

DISPLAY=:1 xvfb-run java -jar selenium-server-standalone-2.0b3.jar

xvfb-run does the whole X authority dance for you, give it a try!

Just adding a parameter like the below worked for me.

cursor=conn.cursor(dictionary=True)

I hope this would be helpful either.

I have found the creates option in the command module useful. How about this:

- name: Move foo to bar
  command: creates="path/to/bar" mv /path/to/foo /path/to/bar

I used to do a 2 task approach using stat like Bruce P suggests. Now I do this as one task with creates. I think this is a lot clearer.

Here i have mentioned the simple syntex for create json file and print the array value inside the json file in pretty manner.

$array = array('name' => $name,'id' => $id,'url' => $url);
$fp = fopen('results.json', 'w');
fwrite($fp, json_encode($array, JSON_PRETTY_PRINT));   // here it will print the array pretty
fclose($fp);

Hope it will works for you....

This may help you.

$today = date("m-d-Y H:i:s");
$thisMonth =date("m");
$thisYear = date("y");
$expectedDate = ($thisMonth+1)."-08-$thisYear 23:58:00";


if (strtotime($expectedDate) > strtotime($today)) {
    echo "Expected date is greater then current date";
    return ;
} else
{
 echo "Expected date is lesser then current date";
}

Is there any equivalent for the truststore? How can I view the trusted certificates?

Yes there is.The exact same command since keystore and truststore differ only in what they store i.e. private key or signed public key (certificate)

No other difference

I would prefere

if (!myStr.empty())
{
    //do something
}

Also you don't have to write std::string a = "";. You can just write std::string a; - it will be empty by default

You can do it in one line by converting your lists to sets and using set.difference:

item_list = ['item', 5, 'foo', 3.14, True]
list_to_remove = ['item', 5, 'foo']

final_list = list(set(item_list) - set(list_to_remove))

Would give you the following output:

final_list = [3.14, True]

Note: this will remove duplicates in your input list and the elements in the output can be in any order (because sets don't preserve order). It also requires all elements in both of your lists to be hashable.

If in the connection string you have specified:

User ID=xxx;Password=yyy

but in the connection string there is:

Trusted_Connection=true;

SQL Server will use Windows Authentication, so your connection values will be ignored and overridden (IIS will use the Windows account specified in Identity user profile). more info here

The same applies if in the connection string there is:

 Integrated Security = true;

or

 Integrated Security = SSPI;

because Windows Authentication will be used to connect to the database server. more info here

My solution is:

1. Copy dll Microsoft.ReportViewer.WebForms.dll into Bin folder in your project.
2. Remove your reference.
3. Add new reference from bin folder.

I hope this can help.

The PostgreSQL manual indicates that this means the transaction is open (inside BEGIN) and idle. It's most likely a user connected using the monitor who is thinking or typing. I have plenty of those on my system, too.

If you're using Slony for replication, however, the Slony-I FAQ suggests idle in transaction may mean that the network connection was terminated abruptly. Check out the discussion in that FAQ for more details.

If the data frame and Series object have the same index, pandas.concat also works here:

e
#0   -0.335485
#1   -1.166658
#2   -0.385571

# here we need to give the series object a name which converts to the new  column name 
# in the result
df = pd.concat([df, e.rename("e")], axis=1)
df

#2  0.614758     0.075793   -0.451460   -0.012493   -0.385571

In case they don't have the same index:

e.index = df.index
df = pd.concat([df, e.rename("e")], axis=1)

May come in handy to check syntax of Nginx's configuration files by running:

nginx -t -c /etc/nginx/nginx.conf

Use one of the forms of string::insert:

std::string str("lolcat");
str.insert(0, 5, '.');

This will insert "....." (five dots) at the start of the string (position 0).

Just a quick contribution.

Since the current python docs don't have "window" in the itertool examples (i.e., at the bottom of http://docs.python.org/library/itertools.html), here's an snippet based on the code for grouper which is one of the examples given:

import itertools as it
def window(iterable, size):
    shiftedStarts = [it.islice(iterable, s, None) for s in xrange(size)]
    return it.izip(*shiftedStarts)

Basically, we create a series of sliced iterators, each with a starting point one spot further forward. Then, we zip these together. Note, this function returns a generator (it is not directly a generator itself).

Much like the appending-element and advancing-iterator versions above, the performance (i.e., which is best) varies with list size and window size. I like this one because it is a two-liner (it could be a one-liner, but I prefer naming concepts).

It turns out that the above code is wrong. It works if the parameter passed to iterable is a sequence but not if it is an iterator. If it is an iterator, the same iterator is shared (but not tee'd) among the islice calls and this breaks things badly.

Here is some fixed code:

import itertools as it
def window(iterable, size):
    itrs = it.tee(iterable, size)
    shiftedStarts = [it.islice(anItr, s, None) for s, anItr in enumerate(itrs)]
    return it.izip(*shiftedStarts)

Also, one more version for the books. Instead of copying an iterator and then advancing copies many times, this version makes pairwise copies of each iterator as we move the starting position forward. Thus, iterator t provides both the "complete" iterator with starting point at t and also the basis for creating iterator t + 1:

import itertools as it
def window4(iterable, size):
    complete_itr, incomplete_itr = it.tee(iterable, 2)
    iters = [complete_itr]
    for i in xrange(1, size):
        incomplete_itr.next()
        complete_itr, incomplete_itr = it.tee(incomplete_itr, 2)
        iters.append(complete_itr)
    return it.izip(*iters)

function randomIntFromInterval(min, max) { // min and max included 
  return Math.floor(Math.random() * (max - min + 1) + min);
}

What it does "extra" is it allows random intervals that do not start with 1. So you can get a random number from 10 to 15 for example. Flexibility.

Here is your string XOR'er, presumably for some mild form of encryption:

>>> src = "Hello, World!"
>>> code = "secret"
>>> xorWord = lambda ss,cc: ''.join(chr(ord(s)^ord(c)) for s,c in zip(ss,cc*100))
>>> encrypt = xorWord(src, code)
>>> encrypt
';\x00\x0f\x1e\nXS2\x0c\x00\t\x10R'
>>> decrypt = xorWord(encrypt,code)
>>> print decrypt
Hello, World!

Note that this is an extremely weak form of encryption. Watch what happens when given a blank string to encode:

>>> codebreak = xorWord("      ", code)
>>> print codebreak
SECRET

I think it would be interesting to write both of them in a way that only by switching some lines of code would give you one algorithm or the other, so that you will see that your dillema is not so strong as it seems to be at first.

I personally like the interpretation of BFS as flooding a landscape: the low altitude areas will be flooded first, and only then the high altitude areas would follow. If you imagine the landscape altitudes as isolines as we see in geography books, its easy to see that BFS fills all area under the same isoline at the same time, just as this would be with physics. Thus, interpreting altitudes as distance or scaled cost gives a pretty intuitive idea of the algorithm.

With this in mind, you can easily adapt the idea behind breadth first search to find the minimum spanning tree easily, shortest path, and also many other minimization algorithms.

I didnt see any intuitive interpretation of DFS yet (only the standard one about the maze, but it isnt as powerful as the BFS one and flooding), so for me it seems that BFS seems to correlate better with physical phenomena as described above, while DFS correlates better with choices dillema on rational systems (ie people or computers deciding which move to make on a chess game or going out of a maze).

So, for me the difference between lies on which natural phenomenon best matches their propagation model (transversing) in real life.

The easisest thing to do is to wrap your code in a transaction, and then execute each batch of T-SQL code line by line.

For example,

Begin Transaction

         -Do some T-SQL queries here.

Rollback transaction -- OR commit transaction

If you want to incorporate error handling you can do so by using a TRY...CATCH BLOCK. Should an error occur you can then rollback the tranasction within the catch block.

For example:

USE AdventureWorks;
GO
BEGIN TRANSACTION;

BEGIN TRY
    -- Generate a constraint violation error.
    DELETE FROM Production.Product
    WHERE ProductID = 980;
END TRY
BEGIN CATCH
    SELECT 
        ERROR_NUMBER() AS ErrorNumber
        ,ERROR_SEVERITY() AS ErrorSeverity
        ,ERROR_STATE() AS ErrorState
        ,ERROR_PROCEDURE() AS ErrorProcedure
        ,ERROR_LINE() AS ErrorLine
        ,ERROR_MESSAGE() AS ErrorMessage;

    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION;
END CATCH;

IF @@TRANCOUNT > 0
    COMMIT TRANSACTION;
GO

There is indeed a fancy shmancy native function in java you should leverage.

ArrayList has an instance method called

indexOf(Object o)

(http://docs.oracle.com/javase/6/docs/api/java/util/ArrayList.html)

You would be able to call it on _categories as follows:

_categories.indexOf("camels")

I have no experience with programming for Android - but this would work for a standard Java application.

Good luck.

Heh, came searching for a similar answer. Then it hit me.

{{ p.User['first_name'] if p is not none else 'NONE' }}

or if you need an empty string:

{{ p.User['first_name'] if p is not none }}

I don't understand how can datenwolf`s index generation can be correct. But still I find his solution rather clear. This is what I get after some thinking:

inline void push_indices(vector<GLushort>& indices, int sectors, int r, int s) {
    int curRow = r * sectors;
    int nextRow = (r+1) * sectors;

    indices.push_back(curRow + s);
    indices.push_back(nextRow + s);
    indices.push_back(nextRow + (s+1));

    indices.push_back(curRow + s);
    indices.push_back(nextRow + (s+1));
    indices.push_back(curRow + (s+1));
}

void createSphere(vector<vec3>& vertices, vector<GLushort>& indices, vector<vec2>& texcoords,
             float radius, unsigned int rings, unsigned int sectors)
{
    float const R = 1./(float)(rings-1);
    float const S = 1./(float)(sectors-1);

    for(int r = 0; r < rings; ++r) {
        for(int s = 0; s < sectors; ++s) {
            float const y = sin( -M_PI_2 + M_PI * r * R );
            float const x = cos(2*M_PI * s * S) * sin( M_PI * r * R );
            float const z = sin(2*M_PI * s * S) * sin( M_PI * r * R );

            texcoords.push_back(vec2(s*S, r*R));
            vertices.push_back(vec3(x,y,z) * radius);
            push_indices(indices, sectors, r, s);
        }
    }
}

FWIW: I got the same error for a different reason. I post the answer here not for the benefit of the OP, but for the benefit of those who may end up on this page due to its title... who might have made the same mistake I did.

I was confused why I was getting "local variable referenced before assignment" because I was calling a FUNCTION that I knew was already defined:

def job_fn(job):
  return job + ".job"

def do_something():
  a = 1
  b = 2
  job_fn = job_fn("foo")

do_something()

This was giving:

UnboundLocalError: local variable 'job_fn' referenced before assignment

Took me a while to see my obvious problem: I used a local variable named job_fn which masked the ability to see the prior function definition for job_fn.

Hardware

If a GPU device has, for example, 4 multiprocessing units, and they can run 768 threads each: then at a given moment no more than 4*768 threads will be really running in parallel (if you planned more threads, they will be waiting their turn).

Software

threads are organized in blocks. A block is executed by a multiprocessing unit. The threads of a block can be indentified (indexed) using 1Dimension(x), 2Dimensions (x,y) or 3Dim indexes (x,y,z) but in any case xyz <= 768 for our example (other restrictions apply to x,y,z, see the guide and your device capability).

Obviously, if you need more than those 4*768 threads you need more than 4 blocks. Blocks may be also indexed 1D, 2D or 3D. There is a queue of blocks waiting to enter the GPU (because, in our example, the GPU has 4 multiprocessors and only 4 blocks are being executed simultaneously).

Now a simple case: processing a 512x512 image

Suppose we want one thread to process one pixel (i,j).

We can use blocks of 64 threads each. Then we need 512*512/64 = 4096 blocks (so to have 512x512 threads = 4096*64)

It's common to organize (to make indexing the image easier) the threads in 2D blocks having blockDim = 8 x 8 (the 64 threads per block). I prefer to call it threadsPerBlock.

dim3 threadsPerBlock(8, 8);  // 64 threads

and 2D gridDim = 64 x 64 blocks (the 4096 blocks needed). I prefer to call it numBlocks.

dim3 numBlocks(imageWidth/threadsPerBlock.x,  /* for instance 512/8 = 64*/
              imageHeight/threadsPerBlock.y); 

The kernel is launched like this:

myKernel <<<numBlocks,threadsPerBlock>>>( /* params for the kernel function */ );       

Finally: there will be something like "a queue of 4096 blocks", where a block is waiting to be assigned one of the multiprocessors of the GPU to get its 64 threads executed.

In the kernel the pixel (i,j) to be processed by a thread is calculated this way:

uint i = (blockIdx.x * blockDim.x) + threadIdx.x;
uint j = (blockIdx.y * blockDim.y) + threadIdx.y;

The documentation says (also here):

If npm was invoked with root privileges, then it will change the uid to the user account or uid specified by the user config, which defaults to nobody. Set the unsafe-perm flag to run scripts with root privileges.

Your options are:

1. Run npm install with the --unsafe-perm flag:

   [sudo] npm install --unsafe-perm
   

2. Add the unsafe-perm flag to your package.json:

   "config": {
       "unsafe-perm":true
   }
   

3. Don't use the preinstall script to install global modules, install them separately and then run the regular npm install without root privileges:

   sudo npm install -g coffee-script node-gyp
   npm install

The problem is caused because you need to import the pageNumber.Member class in your JSP. Make sure to also include another packages and classes like java.util.List.

For apache look up SymLink or you can solve via the OS with Symbolic Links or on linux set up a library link/etc

My answer is one method specifically to windows 10.

So my method involves mapping a network drive to U:/ (e.g. I use G:/ for Google Drive)

open cmd and type hostname (example result: LAPTOP-G666P000, you could use your ip instead, but using a static hostname for identifying yourself makes more sense if your network stops)

Press Windows_key + E > right click 'This PC' > press N (It's Map Network drive, NOT add a network location)

If you are right clicking the shortcut on the desktop you need to press N then enter

Fill out U: or G: or Z: or whatever you want Example Address: \\LAPTOP-G666P000\c$\Users\username\

Then you can use <a href="file:///u:/2ndFile.html"><button type="submit">Local file</button> like in your question

related: You can also use this method for FTPs, and setup multiple drives for different relative paths on that same network.

related2: I have used http://localhost/c$ etc before on some WAMP/apache servers too before, you can use .htaccess for control/security but I recommend to not do so on a live/production machine -- or any other symlink documentroot example you can google

You are using a relative path, which means that the program looks for the file in the working directory. The error is telling you that there is no file of that name in the working directory.

Try using the exact, or absolute, path.

if you want to upgrade only a single column of a table row then you can use as following:

$this->db->set('column_header', $value); //value that used to update column  
$this->db->where('column_id', $column_id_value); //which row want to upgrade  
$this->db->update('table_name');  //table name

Because you have multiple versions of NumPy installed.

Try pip uninstall numpy and pip list | grep numpy several times, until you see no output from pip list | grep numpy.

Then pip install numpy will get you the newest version of NumPy.

on socket.io 1.3.4 you have the following possibilities.

socket.handshake.address,

socket.conn.remoteAddress or

socket.request.client._peername.address

You can't access element like you did (document.frm_new_user_request). You have to use the function getElementById:

document.getElementById("frm_new_user_request")

So getting a value from an input could look like this:

var value = document.getElementById("frm_new_user_request").value

Also you can use some JavaScript framework, e.g. jQuery, which simplifies operations with DOM (Document Object Model) and also hides differences between various browsers from you.

Getting a value from an input using jQuery would look like this:

• input with ID "element": var value = $("#element).value
• input with class "element": var value = $(".element).value

If lines with only whitespace can be considered empty too, then you can use the regex "(\s*\n\s*)+" to not count them.

Had same issue when I had to develop a fixed length field format.

Usually we do not use line separator for binary files but For some reason our customer wished to add a line break as separator between records. They set

< record_delimiter value="\n"/ >

but this didn't work as records got two additional characters:
< record1 > \n < record2 > \n.... and so on.

Did following change and it just worked.

< record_delimiter value="\n"/> => < record_delimiter value="&#xA;"/ >

After unmarshaling Java interprets as new line character.

You can just use the TimeOfDay property of date time, which is TimeSpan type:

DateTime.TimeOfDay

Assuming you really mean easiest and are not necessarily looking for a way to do this programmatically, you can do this:

1. Add, if not already there, a row of "column Musicians" to the spreadsheet. That is, if you have data in columns such as:

   Rory Gallagher      Guitar
   Gerry McAvoy        Bass
   Rod de'Ath          Drums
   Lou Martin          Keyboards
   Donkey Kong Sioux   Self-Appointed Semi-official Stomper
   

   Note: you might want to add "Musician" and "Instrument" in row 0 (you might have to insert a row there)

2. Save the file as a CSV file.

3. Copy the contents of the CSV file to the clipboard

4. Go to http://www.convertcsv.com/csv-to-json.htm

5. Verify that the "First row is column names" checkbox is checked

6. Paste the CSV data into the content area

7. Mash the "Convert CSV to JSON" button

   With the data shown above, you will now have:

   [
     {
       "MUSICIAN":"Rory Gallagher",
       "INSTRUMENT":"Guitar"
     },
     {
       "MUSICIAN":"Gerry McAvoy",
       "INSTRUMENT":"Bass"
     },
     {
       "MUSICIAN":"Rod D'Ath",
       "INSTRUMENT":"Drums"
     },
     {
       "MUSICIAN":"Lou Martin",
       "INSTRUMENT":"Keyboards"
     }
     {
       "MUSICIAN":"Donkey Kong Sioux",
       "INSTRUMENT":"Self-Appointed Semi-Official Stomper"
     }
   ]
   

   With this simple/minimalistic data, it's probably not required, but with large sets of data, it can save you time and headache in the proverbial long run by checking this data for aberrations and abnormalcy.

8. Go here: http://jsonlint.com/

9. Paste the JSON into the content area

10. Pres the "Validate" button.

If the JSON is good, you will see a "Valid JSON" remark in the Results section below; if not, it will tell you where the problem[s] lie so that you can fix it/them.

Question#1 - These are the only way to handle view clicks.

Question#2 -
Option#1/Option#4 - There's not much difference between option#1 and option#4. The only difference I see is in one case activity is implementing the OnClickListener, whereas, in the other case, there'd be an anonymous implementation.

Option#2 - In this method an anonymous class will be generated. This method is a bit cumborsome, as, you'd need to do it multiple times, if you have multiple buttons. For Anonymous classes, you have to be careful for handling memory leaks.

Option#3 - Though, this is a easy way. Usually, Programmers try not to use any method until they write it, and hence this method is not widely used. You'd see mostly people use Option#4. Because it is cleaner in term of code.

If you just need to output the date in ISO8601 format including the trailing Z and you are on at least SQL Server 2012, then you may use FORMAT:

SELECT FORMAT(GetUtcDate(),'yyyy-MM-ddTHH:mm:ssZ')

This will give you something like:

2016-02-18T21:34:14Z

Just as @Pxtl points out in a comment FORMAT may have performance implications, a cost that has to be considered compared to any flexibility it brings.

also be aware that if you are creating a array within a method, you cannot return it. If you return a pointer to it, it would have been removed from the stack when the function returns. you must allocate memory onto the heap and return a pointer to that. eg.

//this is bad
char* getname()
{
  char name[100];
  return name;
}

//this is better
char* getname()
{
  char *name = malloc(100);
  return name;
  //remember to free(name)
}

Mostly in Hibernate , need to add the Entity class in hibernate.cfg.xml like-

<hibernate-configuration>
  <session-factory>

    ....
    <mapping class="xxx.xxx.yourEntityName"/>
 </session-factory>
</hibernate-configuration>

npm install --save-dev @angular-devkit/build-angular

It's Install @angular-devkit/build-angular as dev dependency. This package is newly introduced in Angular 6.0

The include path is set against the server configuration (PHP.ini) but the include path you specify is relative to that path so in your case the include path is (actual path in windows):

C:\xampp\php\PEAR\initcontrols\header_myworks.php

providing the path you pasted in the subject is correct. Make sure your file is located there.

For more info you can get and set the include path programmatically.

What about the SystemParameters class in PresentationFramework? It has a WorkArea property that seems to be what you are looking for.

But, why won't setting the Window.WindowStartupLocation work? CenterScreen is one of the enum values. Do you have to tweak the centering?

I am going to assume this is a WinForms questions (which it feels like, based on it being a "program" rather than a website/app). In which case you can simple do the following to change the text colour of a label:

myLabel.ForeColor = System.Drawing.Color.Red;

Or any other colour of your choice. If you want to be more specific you can use an RGB value like so:

myLabel.ForeColor = Color.FromArgb(0, 0, 0);//(R, G, B) (0, 0, 0 = black)

Having different colours for different users can be done a number of ways. For example, you could allow each user to specify their own RGB value colours, store these somewhere and then load them when the user "connects".

An alternative method could be to just use 2 colours - 1 for the current user (running the app) and another colour for everyone else. This would help the user quickly identify their own messages above others.

A third approach could be to generate the colour randomly - however you will likely get conflicting values that do not show well against your background, so I would suggest not taking this approach. You could have a pre-defined list of "acceptable" colours and just pop one from that list for each user that joins.

Per Arvand:
Eclipse: Simply type android.R.layout.simple_list_item_1 somewhere in code, hold Ctrl, hover over simple_list_item_1, and from the dropdown that appears select Open declaration in layout/simple_list_item_1.xml. It'll direct you to the contents of the XML.

From there, if you then hover over the resulting simple_list_item_1.xml tab in the Editor, you'll see the file is located at C:\Data\applications\Android\android-sdk\platforms\android-19\data\res\layout\simple_list_item_1.xml (or equivalent location for your installation).

I was also stuck for two days because of the same reason, actually Scrolling will make it work, because may be the data couldn't load properly, which may cause the same error again and again.

What I did is, I scroll down randomly, once with (0,-500), then (0,400), then (0.-600), you may give these scroll value according to your use. Just scroll it where you have the content to click.

driver.execute_script("scrollBy(0,-500);")
sleep(5)

driver.execute_script("scrollBy(0,400);")
sleep(5)

driver.execute_script("scrollBy(0,-600);")
sleep(5)

It really worked :)

You can call javascript functions from c# using Jering.Javascript.NodeJS, an open-source library by my organization:

string javascriptModule = @"
module.exports = (callback, x, y) => {  // Module must export a function that takes a callback as its first parameter
    var result = x + y; // Your javascript logic
    callback(null /* If an error occurred, provide an error object or message */, result); // Call the callback when you're done.
}";

// Invoke javascript
int result = await StaticNodeJSService.InvokeFromStringAsync<int>(javascriptModule, args: new object[] { 3, 5 });

// result == 8
Assert.Equal(8, result);

The library supports invoking directly from .js files as well. Say you have file C:/My/Directory/exampleModule.js containing:

module.exports = (callback, message) => callback(null, message);

You can invoke the exported function:

string result = await StaticNodeJSService.InvokeFromFileAsync<string>("C:/My/Directory/exampleModule.js", args: new[] { "test" });

// result == "test"
Assert.Equal("test", result);

A shell convention is that a successful executable should exit with the value 0. Anything else can be interpreted as a failure of some sort, on part of bash or the executable you that just ran. See also $PIPESTATUS and the EXIT STATUS section of the bash man page:

   For  the shell’s purposes, a command which exits with a zero exit status has succeeded.  An exit status
   of zero indicates success.  A non-zero exit status indicates failure.  When a command terminates  on  a
   fatal signal N, bash uses the value of 128+N as the exit status.

   If  a command is not found, the child process created to execute it returns a status of 127.  If a com-
   mand is found but is not executable, the return status is 126.

   If a command fails because of an error during expansion or redirection, the exit status is greater than
   zero.

   Shell  builtin  commands  return  a  status of 0 (true) if successful, and non-zero (false) if an error
   occurs while they execute.  All builtins return an exit status of 2 to indicate incorrect usage.

   Bash itself returns the exit status of the last command executed, unless  a  syntax  error  occurs,  in
   which case it exits with a non-zero value.  See also the exit builtin command below.

Assuming you've got access to a standard Unix shell and/or cygwin environment:

tr -s ' ' '\n' < yourfile | sort | uniq -d -c
       ^--space char

Basically: convert all space characters to linebreaks, then sort the tranlsated output and feed that to uniq and count duplicate lines.

Consider using a the transform: rotate(-90deg) style on an element. See http://www.w3schools.com/cssref/css3_pr_transform.asp

Example, In your css

.verticaltext_content {
  position: relative;
  transform: rotate(-90deg);
  right:90px;   //These three positions need adjusting
  bottom:150px; //based on your actual chart size
  width:200px;
}

Add a space fudge factor to the Y Axis scale so the text has room to render in your javascript.

scaleLabel: "      <%=value%>"

Then in your html after your chart canvas put something like...

<div class="text-center verticaltext_content">Y Axis Label</div>

It is not the most elegant solution, but worked well when I had a few layers between the html and the chart code (using angular-chart and not wanting to change any source code).

while(listbox.Items.Remove(s)) ; should work, as well. However, I think the backwards solution is the fastest.

One solution is to create a named class instead of using an anonymous class. Give that named class a constructor that takes whatever parameters you wish and assigns them to class fields:

class MenuActionListener implements ActionListener {
    private Color kolorIkony;

    public MenuActionListener(Color kolorIkony) {
        this.kolorIkony = kolorIkony
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        JMenuItem item = (JMenuItem) e.getSource();
        IconA icon = (IconA) item.getIcon();
        // Use the class field here
        textArea.setForeground(kolorIkony);
    }
});

Now you can create an instance of this class as usual:

Jmi.addActionListener(new MenuActionListener(getColor(colors[mi]));

If you want a Popup that closes automatically, you should look for Toasts. But if you want a dialog that the user has to close first before proceeding, you should look for a Dialog.

For both approaches it is possible to read a text file with the text you want to display. But you could also hardcode the text or use R.String to set the text.

Posted it also here: How to run powershell command in batch file

Following this thread:
https://community.idera.com/database-tools/powershell/powertips/b/tips/posts/converting-powershell-to-batch


you can convert any PowerShell script into a batch file easily using this PowerShell function:

function Convert-PowerShellToBatch
{
    param
    (
        [Parameter(Mandatory,ValueFromPipeline,ValueFromPipelineByPropertyName)]
        [string]
        [Alias("FullName")]
        $Path
    )
 
    process
    {
        $encoded = [Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes((Get-Content -Path $Path -Raw -Encoding UTF8)))
        $newPath = [Io.Path]::ChangeExtension($Path, ".bat")
        "@echo off`npowershell.exe -NoExit -encodedCommand $encoded" | Set-Content -Path $newPath -Encoding Ascii
    }
}

To convert all PowerShell scripts inside a directory, simply run the following command:

Get-ChildItem -Path <DIR-PATH> -Filter *.ps1 |
  Convert-PowerShellToBatch

Where is the path to the desired folder. For instance:

Get-ChildItem -Path "C:\path\to\powershell\scripts" -Filter *.ps1 |
  Convert-PowerShellToBatch

To convert a single PowerShell script, simply run this:

Get-ChildItem -Path <FILE-PATH> |
  Convert-PowerShellToBatch

Where is the path to the desired file.

The converted files are located in the source directory. i.e., <FILE-PATH> or <DIR-PATH>.

Putting it all together:
create a .ps1 file (PowerShell script) with the following code in it:

function Convert-PowerShellToBatch
{
    param
    (
        [Parameter(Mandatory,ValueFromPipeline,ValueFromPipelineByPropertyName)]
        [string]
        [Alias("FullName")]
        $Path
    )
 
    process
    {
        $encoded = [Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes((Get-Content -Path $Path -Raw -Encoding UTF8)))
        $newPath = [Io.Path]::ChangeExtension($Path, ".bat")
        "@echo off`npowershell.exe -NoExit -encodedCommand $encoded" | Set-Content -Path $newPath -Encoding Ascii
    }
}

# change <DIR> to the path of the folder in which the desired powershell scripts are.
# the converted files will be created in the destination path location (in <DIR>).
Get-ChildItem -Path <DIR> -Filter *.ps1 |
  Convert-PowerShellToBatch

And don't forget, if you wanna convert only one file instead of many, you can replace the following

Get-ChildItem -Path <DIR> -Filter *.ps1 |
  Convert-PowerShellToBatch

with this:

Get-ChildItem -Path <FILE-PATH> |
  Convert-PowerShellToBatch

as I explained before.

Or you can use a for-each loop:

Collection<X> items = ...;
X last = null;
for (X x : items) last = x;

Avoid overflow bug

unsigned i, number;
...
for (i=2; i*i<=number; i++) {  // Buggy
for (i=2; i*i<=number; i += 2) {  // Buggy
// or
for (i=5; i*i<=number; i+=6) { // Buggy

These forms are incorrect when number is a prime and i*i is near the max value of the type.

Problem exists with all integer types, signed, unsigned and wider.

Example:

Let UINT_MAX_SQRT as the floor of the square root of the maximum integer value. E.g. 65535 when unsigned is 32-bit.

With for (i=2; i*i<=number; i++), this 10-year old failure occurs because when UINT_MAX_SQRT*UINT_MAX_SQRT <= number and number is a prime, the next iteration results in a multiplication overflow. Had the type been a signed type, the overflow is UB. With unsigned types, this itself is not UB, yet logic has broken down. Interations continue until a truncated product exceeds number. An incorrect result may occur. With 32-bit unsigned, try 4,294,967,291? which is a prime.

If some_integer_type_MAX been a Mersenne Prime, i*i<=number is never true.

To avoid this bug, consider that number%i, number/i is efficient on many compilers as the calculations of the quotient and remainder are done together, thus incurring no extra cost to do both vs. just 1.

A simple full-range solution:

bool IsPrime(unsigned number) {
    for(unsigned i = 2; i <= number/i; i++){
        if(number % i == 0){
            return false;
        }
    }
    return number >= 2;
}

Use Integer.compare(int, int). And don'try to micro-optimize your code unless you can prove that you have a performance issue.

Use CSS3

.container {
   -webkit-column-count: 2;
      -moz-column-count: 2;
           column-count: 2;

   -webkit-column-gap: 20px;
      -moz-column-gap: 20px;
           column-gap: 20px;
}

The answer is that you have to use TableRow.LayoutParams, not LinearLayout.LayoutParams or any other LayoutParams.

TextView tv = new TextView(v.getContext());
LayoutParams params = new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1f);
tv.setLayoutParams(params);

The different LayoutParams are not interchangeable and if you use the wrong one then nothing seems to happen. The text view's parent is a table row, hence:

http://developer.android.com/reference/android/widget/TableRow.LayoutParams.html

This is an old question, but I stumbled onto this when looking for the answer so I wanted to give the update to the answer for reference.

The methods save and update are deprecated.

save(to_save, manipulate=True, check_keys=True, **kwargs)¶ Save a document in this collection.

DEPRECATED - Use insert_one() or replace_one() instead.

Changed in version 3.0: Removed the safe parameter. Pass w=0 for unacknowledged write operations.

update(spec, document, upsert=False, manipulate=False, multi=False, check_keys=True, **kwargs) Update a document(s) in this collection.

DEPRECATED - Use replace_one(), update_one(), or update_many() instead.

Changed in version 3.0: Removed the safe parameter. Pass w=0 for unacknowledged write operations.

in the OPs particular case, it's better to use replace_one.

A data contract is a formal agreement between a service and a client that abstractly describes the data to be exchanged. That is, to communicate, the client and the service do not have to share the same types, only the same data contracts. A data contract precisely defines, for each parameter or return type, what data is serialized (turned into XML) to be exchanged.

Windows Communication Foundation (WCF) uses a serialization engine called the Data Contract Serializer by default to serialize and deserialize data (convert it to and from XML). All .NET Framework primitive types, such as integers and strings, as well as certain types treated as primitives, such as DateTime and XmlElement, can be serialized with no other preparation and are considered as having default data contracts. Many .NET Framework types also have existing data contracts.

You can find the full article here.

You can achieve this by using the following method (as mentioned in other answers):

strCmdText = "'/C some command";
Process.Start("CMD.exe", strCmdText);

When I tried the methods listed above I found that my custom command did not work using the syntax of some of the answers above.

I found out more complex commands need to be encapsulated in quotes to work:

string strCmdText;
strCmdText = "'/C cd " + path + " && composer update && composer install -o'";
Process.Start("CMD.exe", strCmdText);

No, because it contains items there must be an instance of it. Its items being null is irrelevant, so the statment ((arrayList) != null) == true

Use the .c_str() method for const char *.

You can use &mystring[0] to get a char * pointer, but there are a couple of gotcha's: you won't necessarily get a zero terminated string, and you won't be able to change the string's size. You especially have to be careful not to add characters past the end of the string or you'll get a buffer overrun (and probable crash).

There was no guarantee that all of the characters would be part of the same contiguous buffer until C++11, but in practice all known implementations of std::string worked that way anyway; see Does “&s[0]” point to contiguous characters in a std::string?.

Note that many string member functions will reallocate the internal buffer and invalidate any pointers you might have saved. Best to use them immediately and then discard.

You can also use Url.Action for the path instead like so:

$.ajax({
        url: "@Url.Action("Holiday", "Calendar", new { area = "", year= (val * 1) + 1 })",                
        type: "GET",           
        success: function (partialViewResult) {            
            $("#refTable").html(partialViewResult);
        }
    });

Basic implementation using MultipartFormDataContent :-

HttpClient httpClient = new HttpClient();
MultipartFormDataContent form = new MultipartFormDataContent();

form.Add(new StringContent(username), "username");
form.Add(new StringContent(useremail), "email");
form.Add(new StringContent(password), "password");            
form.Add(new ByteArrayContent(file_bytes, 0, file_bytes.Length), "profile_pic", "hello1.jpg");
HttpResponseMessage response = await httpClient.PostAsync("PostUrl", form);

response.EnsureSuccessStatusCode();
httpClient.Dispose();
string sd = response.Content.ReadAsStringAsync().Result;

(C++17 and above):

can use std::search also

This is also useful for searching sequence of elements.

#include <algorithm>
#include <iostream>
#include <vector>

template <typename Container>
bool search_vector(const Container& vec, const Container& searchvec)
{
    return std::search(vec.begin(), vec.end(), searchvec.begin(), searchvec.end()) != vec.end();
}

int main()
{
     std::vector<int> v = {2,4,6,8};

     //THIS WORKS. SEARCHING ONLY ONE ELEMENT.
     std::vector<int> searchVector1 = {2};
     if(search_vector(v,searchVector1))
         std::cout<<"searchVector1 found"<<std::endl;
     else
         std::cout<<"searchVector1 not found"<<std::endl;

     //THIS WORKS, AS THE ELEMENTS ARE SEQUENTIAL.
     std::vector<int> searchVector2 = {6,8};
     if(search_vector(v,searchVector2))
         std::cout<<"searchVector2 found"<<std::endl;
     else
         std::cout<<"searchVector2 not found"<<std::endl;

     //THIS WILL NOT WORK, AS THE ELEMENTS ARE NOT SEQUENTIAL.
     std::vector<int> searchVector3 = {8,6};
     if(search_vector(v,searchVector3))
         std::cout<<"searchVector3 found"<<std::endl;
     else
         std::cout<<"searchVector3 not found"<<std::endl;
}

Also there is flexibility of passing some search algorithms. Refer here.

6 and 7 Because static variable intialise only once, So 5++ becomes 6 at 1st call 6++ becomes 7 at 2nd call Note-when 2nd call occurs it takes x value is 6 instead of 5 because x is static variable.

Realise this is an old thread, but after seeing lots of scripts like this I noticed that you can do this just using conditional formatting.

Assuming the "Status" was Column D:

Highlight cells > right click > conditional formatting. Select "Custom Formula Is" and set the formula as

=RegExMatch($D2,"Complete")

or

=OR(RegExMatch($D2,"Complete"),RegExMatch($D2,"complete"))

Edit (thanks to Frederik Schøning)

=RegExMatch($D2,"(?i)Complete") then set the range to cover all the rows e.g. A2:Z10. This is case insensitive, so will match complete, Complete or CoMpLeTe.

You could then add other rules for "Not Started" etc. The $ is very important. It denotes an absolute reference. Without it cell A2 would look at D2, but B2 would look at E2, so you'd get inconsistent formatting on any given row.

In my case I only wanted the image to behave responsively at mobile scale so I created a css style .myimgrsfix that only kicks in at mobile scale

.myimgrsfix {
    @media(max-width:767px){
        width:100%;
    }
}

and applied that to the image <img class='img-responsive myimgrsfix' src='whatever.gif'>

text-align: center will only work for horizontal centering. For it to be in the complete center, vertical and horizontal you can do the following :

div
{
    position: relative;
}
div img
{
    position: absolute;
    top: 50%;
    left: 50%;
    margin-left: [-50% of your image's width];
    margin-top: [-50% of your image's height];
}

1. You will need InternetExplorer driver executable on your system. So download it from the hinted source (http://www.seleniumhq.org/download/) unpack it and place somewhere you can find it. In my example, I will assume you will place it to C:\Selenium\iexploredriver.exe

2. Then you have to set it up in the system. Here is the Java code pasted from my Selenium project:

   File file = new File("C:/Selenium/iexploredriver.exe");
   System.setProperty("webdriver.ie.driver", file.getAbsolutePath());
   WebDriver driver = new InternetExplorerDriver();
   

Basically, you have to set this property before you initialize driver

Yes, it is mainly to anchor your keywords, in particular the location of your page, so whenever URL loads the page with particular anchor name, then it will be pointed to that particular location.

For example, www.something.com/some_page/#computer if it is very lengthy page and you want to show exactly computer then you can anchor.

<p> adfadsf </p>
<p> adfadsf </p>
<p> adfadsf </p>
<a name="computer"></a><p> Computer topics </p>
<p> adfadsf </p>

Now the page will scroll and bring computer-related topics to the top.

You can try the following:

theAnchorText = "I'm home";

OR

theAnchorText = 'I\'m home';

I think I might have figured this out on Windows. You can run different versions of Chrome at the same time!

Do the following:

• Copy over the version number directory into the usual c:\users\yourUser\appdata\local\google\chrome\application directory (I am assuming you had a backup of the older chrome version directory before the update occurred)

• Copy over the chrome.exe from the older version as a new name such as chrome_custom.exe

• Run chrome as chrome_custom.exe --chrome-version=olderVersion --user-data-dir=newDir

That's it! I use this method to run automated test on Chrome with Selenium, until selenium catches up and works well with the latest Chrome.

With python 3.8+, we can do this with dataclass, and the asdict method that comes with it:

from dataclasses import dataclass, asdict

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker
from sqlalchemy import Column, String, Integer, create_engine

Base = declarative_base()
engine = create_engine('sqlite:///:memory:', echo=False)


@dataclass
class User(Base):
    __tablename__ = 'users'

    id: int = Column(Integer, primary_key=True)
    name: str = Column(String)
    email = Column(String)

    def __init__(self, name):
        self.name = name
        self.email = '[email protected]'


Base.metadata.create_all(engine)

SessionMaker = sessionmaker(bind=engine)
session = SessionMaker()

user1 = User("anurag")
session.add(user1)
session.commit()

query_result = session.query(User).one()  # type: User
print(f'{query_result.id=:}, {query_result.name=:}, {query_result.email=:}')
# query_result.id=1, query_result.name=anurag, [email protected]

query_result_dict = asdict(query_result)
print(query_result_dict)
# {'id': 1, 'name': 'anurag'}

The key is to use the @dataclass decorator, and annotate each column with its type (the : str part of the name: str = Column(String) line).

Also note that since the email is not annotated, it is not included in query_result_dict.

Range("A1").Function="=SUM(Range(Cells(2,1),Cells(3,2)))"

won't work because worksheet functions (when actually used on a worksheet) don't understand Range or Cell

Try

Range("A1").Formula="=SUM(" & Range(Cells(2,1),Cells(3,2)).Address(False,False) & ")"

You import the function from outside the main instance, and don't add it to the methods block. so the context of this is not the vm.

Either do this:

ready() {
  checkAuth.call(this)
}

or add the method to your methods first (which will make Vue bind this correctly for you) and call this method:

methods: {
  checkAuth: checkAuth
},
ready() {
  this.checkAuth()
}

Editor's note: disabling SSL verification has security implications. Without verification of the authenticity of SSL/HTTPS connections, a malicious attacker can impersonate a trusted endpoint such as Gmail, and you'll be vulnerable to a Man-in-the-Middle Attack.

Be sure you fully understand the security issues before using this as a solution.

You can add below code in /config/mail.php ( tested and worked on laravel 5.1, 5.2, 5.4 )

'stream' => [
   'ssl' => [
      'allow_self_signed' => true,
      'verify_peer' => false,
      'verify_peer_name' => false,
   ],
],

Put your wait() function in a loop and wait for all the child processes. The wait function will return -1 and errno will be equal to ECHILD if no more child processes are available.

One way which works for sure

SELECT a.distributor_id,
    (SELECT COUNT(*) FROM myTable WHERE level='personal' and distributor_id = a.distributor_id) as PersonalCount,
    (SELECT COUNT(*) FROM myTable WHERE level='exec' and distributor_id = a.distributor_id) as ExecCount,
    (SELECT COUNT(*) FROM myTable WHERE distributor_id = a.distributor_id) as TotalCount
FROM (SELECT DISTINCT distributor_id FROM myTable) a ;

EDIT:
See @KevinBalmforth's break down of performance for why you likely don't want to use this method and instead should opt for @Taryn?'s answer. I'm leaving this so people can understand their options.

In this instance it will work if it is used within the script before another command has been invoked.

Short answer:

[a[:,:j] for j in i]

What you are trying to do is not a vectorizable operation. Wikipedia defines vectorization as a batch operation on a single array, instead of on individual scalars:

In computer science, array programming languages (also known as vector or multidimensional languages) generalize operations on scalars to apply transparently to vectors, matrices, and higher-dimensional arrays.

...

... an operation that operates on entire arrays can be called a vectorized operation...

In terms of CPU-level optimization, the definition of vectorization is:

"Vectorization" (simplified) is the process of rewriting a loop so that instead of processing a single element of an array N times, it processes (say) 4 elements of the array simultaneously N/4 times.

The problem with your case is that the result of each individual operation has a different shape: (3, 1), (3, 2) and (3, 3). They can not form the output of a single vectorized operation, because the output has to be one contiguous array. Of course, it can contain (3, 1), (3, 2) and (3, 3) arrays inside of it (as views), but that's what your original array a already does.

What you're really looking for is just a single expression that computes all of them:

[a[:,:j] for j in i]

... but it's not vectorized in a sense of performance optimization. Under the hood it's plain old for loop that computes each item one by one.

To get the current router instance or current location you have to create a Higher order component with withRouter from react-router-dom. otherwise, when you are trying to access this.props.location it will return undefined

Example

import React, { Component } from 'react';
import { withRouter } from 'react-router-dom';

class className extends Component {

      render(){
           return(
                ....
                  )
              }
}

export default withRouter(className)

This way I implement upload file to web API in project.

I share for whom concern.

const formData: FormData = new FormData();
formData.append('Image', image, image.name);
formData.append('ComponentId', componentId);
return this.http.post('/api/dashboard/UploadImage', formData);

Step by step

ASP.NET Web API

[HttpPost]
[Route("api/dashboard/UploadImage")]
public HttpResponseMessage UploadImage() 
{
    string imageName = null;
    var httpRequest = HttpContext.Current.Request;
    //Upload Image
    var postedFile = httpRequest.Files["Image"];
    //Create custom filename
    if (postedFile != null)
    {
        imageName = new String(Path.GetFileNameWithoutExtension(postedFile.FileName).Take(10).ToArray()).Replace(" ", "-");
        imageName = imageName + DateTime.Now.ToString("yymmssfff") + Path.GetExtension(postedFile.FileName);
        var filePath = HttpContext.Current.Server.MapPath("~/Images/" + imageName);
        postedFile.SaveAs(filePath);
    }
}

HTML form

<form #imageForm=ngForm (ngSubmit)="OnSubmit(Image)">

    <img [src]="imageUrl" class="imgArea">
    <div class="image-upload">
        <label for="file-input">
            <img src="upload.jpg" />
        </label>

        <input id="file-input" #Image type="file" (change)="handleFileInput($event.target.files)" />
        <button type="submit" class="btn-large btn-submit" [disabled]="Image.value=='' || !imageForm.valid"><i
                class="material-icons">save</i></button>
    </div>
</form>

TS file to use API

OnSubmit(Image) {
    this.dashboardService.uploadImage(this.componentId, this.fileToUpload).subscribe(
      data => {
        console.log('done');
        Image.value = null;
        this.imageUrl = "/assets/img/logo.png";
      }
    );
  }

Service TS

uploadImage(componentId, image) {
        const formData: FormData = new FormData();
        formData.append('Image', image, image.name);
        formData.append('ComponentId', componentId);
        return this.http.post('/api/dashboard/UploadImage', formData);

Not being a developer I found a solution in running multiple ps commands in one line. E.g:

powershell "& 'c:\path with spaces\to\executable.exe' -arguments ; second command ; etc

By placing a " (double quote) before the & (ampersand) it executes the executable. In none of the examples I have found this was mentioned. Without the double quotes the ps prompt opens and waits for input.

Might be useful: https://www.codeproject.com/Articles/6299/Step-by-Step-Calling-C-DLLs-from-VC-and-VB-Part-4

For the example above with "GetWelcomeMessage" you might need to specify "__stdcall" in the typedef field before the function name if getting error after calling imported function.

There could be a mistake in @JARH's answer in the case of a multivariable regression. (I do not have enough reputation to comment.)

In the following line:

p_values =[2*(1-stats.t.cdf(np.abs(i),(len(newX)-1))) for i in ts_b],

the t-values follows a chi-squared distribution of degree len(newX)-1 instead of following a chi-squared distribution of degree len(newX)-len(newX.columns)-1.

So this should be:

p_values =[2*(1-stats.t.cdf(np.abs(i),(len(newX)-len(newX.columns)-1))) for i in ts_b]

(See t-values for OLS regression for more details)

I wanted 2 way conversion, and I wanted to use Python 3 format() support to be most pythonic. Maybe try datasize library module? https://pypi.org/project/datasize/

$ pip install -qqq datasize
$ python
...
>>> from datasize import DataSize
>>> 'My new {:GB} SSD really only stores {:.2GiB} of data.'.format(DataSize('750GB'),DataSize(DataSize('750GB') * 0.8))
'My new 750GB SSD really only stores 558.79GiB of data.'

You were close. You just need to use the duration.asHours() method (see the docs).

var duration = moment.duration(end.diff(startTime));
var hours = duration.asHours();

To enable disable Wifi use the WifiManager class to get system(android device) services for Wifi :

WifiManager wifi =(WifiManager)getSystemService(Context.WIFI_SERVICE); 

Now the object wifi of the WifiManager class is used to get the wifi status:

if(wifi.isWifiEnabled())
    //Perform Operation
else
    //Other Operation

And most importantly do not forget to give the following permission in your Android Manifest File:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
<uses-permission android:name="android.permission.UPDATE_DEVICE_STATS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

To get detailed info and full sample code of the project for enable/disable Wifi on android visit my website link.

If you're using webChromeClient I'll suggest you to use webChromeClient and webViewClient together. because webChromeClient does not provides shouldOverrideUrlLoading. It is okay to use both.

        webview.webViewClient = WebViewClient()
        webview.webChromeClient = Callback()

private inner class Callback : WebChromeClient() {
        override fun onProgressChanged(view: WebView?, newProgress: Int) {
            super.onProgressChanged(view, newProgress)
           
            if (newProgress == 0) {
                progressBar.visibility = View.VISIBLE
            } else if (newProgress == 100) {
                progressBar.visibility = View.GONE
            }
        }

    }

try {                                                                           
    JSONObject jsonObject = new JSONObject(response.body().string());           
    System.out.println(jsonObject);                                             
} catch (JSONException | IOException e ) {                                      
    e.printStackTrace();

If you can live with 01 for January instead of 1, then try...

Use above annotation if someone is facing :--org.hibernate.jpa.HibernatePersistenceProvider persistence provider when it attempted to create the container entity manager factory for the paymentenginePU persistence unit.

Technically yes, but if a string makes sense to be the primary key then you should probably use it. This all depends on the size of the table you're making it for and the length of the string that is going to be the primary key (longer strings == harder to compare). I wouldn't necessarily use a string for a table that has millions of rows, but the amount of performance slowdown you'll get by using a string on smaller tables will be minuscule to the headaches that you can have by having an integer that doesn't mean anything in relation to the data.

exit(X), where X is a number (according to the doc) should work. But it is not recommended by Apple and won't be accepted by the AppStore. Why? Because of these guidelines (one of my app got rejected):

We found that your app includes a UI control for quitting the app. This is not in compliance with the iOS Human Interface Guidelines, as required by the App Store Review Guidelines.

Please refer to the attached screenshot/s for reference.

The iOS Human Interface Guidelines specify,

"Always Be Prepared to Stop iOS applications stop when people press the Home button to open a different application or use a device feature, such as the phone. In particular, people don’t tap an application close button or select Quit from a menu. To provide a good stopping experience, an iOS application should:

Save user data as soon as possible and as often as reasonable because an exit or terminate notification can arrive at any time.

Save the current state when stopping, at the finest level of detail possible so that people don’t lose their context when they start the application again. For example, if your app displays scrolling data, save the current scroll position."

> It would be appropriate to remove any mechanisms for quitting your app.

Plus, if you try to hide that function, it would be understood by the user as a crash.

You could ignore that file with a file in your project base folder:

.gitignore

public/images/*

Then pull the changes and then remove that line from your gitignore file.

You can directly pass boolean parameter in integer column saying that it should be unsigned or not. In laravel 5.4 following code solved my problem.

        $table->integer('user_id', false, true);

Here second parameter false represents that it should not be auto-incrementing and third parameter true represents that it should be unsigned. You can keep foreign key constraint in same migration or separate it. It works on both.

Yes, I believe it should work and it can also be applied to other data types.

For class arrays though, if there are fewer items in the initializer list than elements in the array, the default constructor is used for the remaining elements. If no default constructor is defined for the class, the initializer list must be complete — that is, there must be one initializer for each element in the array.

Don't use a service for this. Create a normal application and create a scheduled task to run it.

This is the commonly held best practice. Jon Galloway agrees with me. Or maybe its the other way around. Either way, the fact is that it is not best practices to create a windows service to perform an intermittent task run off a timer.

"If you're writing a Windows Service that runs a timer, you should re-evaluate your solution."

Since getEntries returns a raw List, it could hold anything.

The warning-free approach is to create a new List<SyndEntry>, then cast each element of the sf.getEntries() result to SyndEntry before adding it to your new list. Collections.checkedList does not do this checking for you—although it would have been possible to implement it to do so.

By doing your own cast up front, you're "complying with the warranty terms" of Java generics: if a ClassCastException is raised, it will be associated with a cast in the source code, not an invisible cast inserted by the compiler.

I tried re-creating this, and .someclass.notip was being generated for me but .someclass:not(.notip) was not, for as long as I did not have the @mixin tip() defined. Once I had that, it all worked.

http://sassmeister.com/gist/9775949

$dropdown-width: 100px;
$comp-tip: true;

@mixin tip($pos:right) {

}

@mixin dropdown-pos($pos:right) {
  &:not(.notip) {
    @if $comp-tip == true{
      @if $pos == right {
        top:$dropdown-width * -0.6;
        background-color: #f00;
        @include tip($pos:$pos);
      }
    }
  }
  &.notip {
    @if $pos == right {
      top: 0;
      left:$dropdown-width * 0.8;
      background-color: #00f;
    }
  }
}

.someclass { @include dropdown-pos(); }

EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'. it what I get when I remove @mixin tip($pos:right) { }

If you want a proper button then you'll need some javascript. Something like this (needs some work on the styling but you get the gist). Wouldn't bother using jquery for something so trivial to be honest.

<html>
<head>
<style type="text/css">
.on { 
border:1px outset;
color:#369;
background:#efefef; 
}

.off {
border:1px outset;
color:#369;
background:#f9d543; 
}
</style>

<script language="javascript">
function togglestyle(el){
    if(el.className == "on") {
        el.className="off";
    } else {
        el.className="on";
    }
}
</script>

</head>

<body>
<input type="button" id="btn" value="button" class="off" onclick="togglestyle(this)" />
</body>
</html>

You can see in pg_log folder if the log configuration is enabled in postgresql.conf with this log directory name.

I assume you are using windows. Open the command prompt and type ipconfig and find out your local address (on your pc) it should look something like 192.168.1.13 or 192.168.0.5 where the end digit is the one that changes. It should be next to IPv4 Address.

If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13 If you have a virtual host then you will need root to edit the hosts file.

If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.

See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.

Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).

If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow to allow,deny in the httpd.conf file. You can access this by the WAMP menu.

To eliminate possible causes of the issue for now set your config file to

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    <RequireAll>
        Require all granted
    </RequireAll>
</Directory>

As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.

Config file that fixed the problem:

https://gist.github.com/samvaughton/6790739

Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.

2017 Update - since WooCommerce 3:

global $product;
$id = $product->get_id();

Woocommerce doesn't like you accessing those variables directly. This will get rid of any warnings from woocommerce if your wp_debug is true.

think simple

<button id="button1" onclick="Click();">ok</button>
<script>
    var buttonClick = false;
    function Click() {
        if (buttonClick) {
            return;
        }
        else {
            buttonClick = true;
            //todo
            alert("ok");
            //buttonClick = false;
        }
    }

The best way around this would be to create an Excel called 'launcher.xlsm' in the same folder as the file you wish to open. In the 'launcher' file put the following code in the 'Workbook' object, but set the constant TargetWBName to be the name of the file you wish to open.

Private Const TargetWBName As String = "myworkbook.xlsx"

'// First, a function to tell us if the workbook is already open...
Function WorkbookOpen(WorkBookName As String) As Boolean
' returns TRUE if the workbook is open
    WorkbookOpen = False
    On Error GoTo WorkBookNotOpen
    If Len(Application.Workbooks(WorkBookName).Name) > 0 Then
        WorkbookOpen = True
        Exit Function
    End If
WorkBookNotOpen:
End Function

Private Sub Workbook_Open()
    'Check if our target workbook is open
    If WorkbookOpen(TargetWBName) = False Then
        'set calculation to manual
        Application.Calculation = xlCalculationManual
        Workbooks.Open ThisWorkbook.Path & "\" & TargetWBName
        DoEvents
        Me.Close False
    End If
End Sub

Set the constant 'TargetWBName' to be the name of the workbook that you wish to open. This code will simply switch calculation to manual, then open the file. The launcher file will then automatically close itself. *NOTE: If you do not wish to be prompted to 'Enable Content' every time you open this file (depending on your security settings) you should temporarily remove the 'me.close' to prevent it from closing itself, save the file and set it to be trusted, and then re-enable the 'me.close' call before saving again. Alternatively, you could just set the False to True after Me.Close

I would use a mysqli connection to connect to the database. Here is an example:

$connection = new mysqli("127.0.0.1", "username", "password", "database_name", 3306);

The next step is to select the information. In your case I would do:

$query = $connection->query("SELECT `names` FROM `Customers`;");

And finally we make an array from all these names by typing:

$array = Array();
while($result = $query->fetch_assoc()){
    $array[] = $result['names'];
}

print_r($array);

So what I've done in this code: I selected all names from the table using a mysql query. Next I use a while loop to check if the $query has a next value. If so the while loop continues and adds that value to the array '$array'. Else the loop stops. And finally I print the array using the 'print_r' method so you can see it all works. I hope this was helpful.

You need to make sure that the value you pass to the directory argument is an absolute path, corrected for the current location of your application.

The best way to do this is to configure UPLOAD_FOLDER as a relative path (no leading slash), then make it absolute by prepending current_app.root_path:

@app.route('/uploads/<path:filename>', methods=['GET', 'POST'])
def download(filename):
    uploads = os.path.join(current_app.root_path, app.config['UPLOAD_FOLDER'])
    return send_from_directory(directory=uploads, filename=filename)

It is important to reiterate that UPLOAD_FOLDER must be relative for this to work, e.g. not start with a /.

A relative path could work but relies too much on the current working directory being set to the place where your Flask code lives. This may not always be the case.

There is a command line option for logging. The output is saved to screenlog.n file, where n is a number of the screen. From man pages of screen:

You don't need to use .html(). You should go with .val().

From the doc of .val():

The .val() method is primarily used to get the values of form elements such as input, select and textarea. When called on an empty collection, it returns undefined.

var message = $('#message').val();

np.max is just an alias for np.amax. This function only works on a single input array and finds the value of maximum element in that entire array (returning a scalar). Alternatively, it takes an axis argument and will find the maximum value along an axis of the input array (returning a new array).

>>> a = np.array([[0, 1, 6],
                  [2, 4, 1]])
>>> np.max(a)
6
>>> np.max(a, axis=0) # max of each column
array([2, 4, 6])

The default behaviour of np.maximum is to take two arrays and compute their element-wise maximum. Here, 'compatible' means that one array can be broadcast to the other. For example:

>>> b = np.array([3, 6, 1])
>>> c = np.array([4, 2, 9])
>>> np.maximum(b, c)
array([4, 6, 9])

But np.maximum is also a universal function which means that it has other features and methods which come in useful when working with multidimensional arrays. For example you can compute the cumulative maximum over an array (or a particular axis of the array):

>>> d = np.array([2, 0, 3, -4, -2, 7, 9])
>>> np.maximum.accumulate(d)
array([2, 2, 3, 3, 3, 7, 9])

This is not possible with np.max.

You can make np.maximum imitate np.max to a certain extent when using np.maximum.reduce:

>>> np.maximum.reduce(d)
9
>>> np.max(d)
9

Basic testing suggests the two approaches are comparable in performance; and they should be, as np.max() actually calls np.maximum.reduce to do the computation.

The Windows separator can be in a Unix filename or Windows Path. The Unix separator can only exist in the Unix path. The presence of a Unix separator indicates a non-Windows path.

The following will strip (cut trailing separator) by the OS specific separator, then split and return the rightmost value. It's ugly, but simple based on the assumption above. If the assumption is incorrect, please update and I will update this response to match the more accurate conditions.

a.rstrip("\\\\" if a.count("/") == 0 else '/').split("\\\\" if a.count("/") == 0 else '/')[-1]

sample code:

b = ['a/b/c/','a/b/c','\\a\\b\\c','\\a\\b\\c\\','a\\b\\c','a/b/../../a/b/c/','a/b/../../a/b/c']

for a in b:

    print (a, a.rstrip("\\" if a.count("/") == 0 else '/').split("\\" if a.count("/") == 0 else '/')[-1])

I got this error because I was doing File.Move to a file path without a file name, need to specify the full path in the destination.

No need to add any extra base64 library. Simple 5 line solution -

var img = new Image();
img.src = path.resolve('sample.jpg');

var doc = new jsPDF('p', 'mm', 'a3');  // optional parameters
doc.addImage(img, 'JPEG', 1, 2);
doc.save("new.pdf");

If the visual studio says that you miss some file in the current source file folder, there is one solution that i used. Just right click the file you want to add and choose Open Document, if it really doesn't exist, then you should see something like cannot find file in the source file path = "somewhere in your computer", then what you could do is the add your source file into that path first and see if it works.

Try this:

;WITH CTE
AS
(
    SELECT DISTINCT
        M1.Product_ID Group_ID,
        M1.Product_ID
    FROM matches M1
        LEFT JOIN matches M2
            ON M1.Product_Id = M2.matching_Product_Id
    WHERE M2.matching_Product_Id IS NULL
    UNION ALL
    SELECT
        C.Group_ID,
        M.matching_Product_Id
    FROM CTE C
        JOIN matches M
            ON C.Product_ID = M.Product_ID
)
SELECT * FROM CTE ORDER BY Group_ID

You can use OPTION(MAXRECURSION n) to control recursion depth.

SQL FIDDLE DEMO

You need to insert the new row and then copy from the source row to the newly inserted row. Excel allows you to paste special just formulas. So in Excel:

• Insert the new row
• Copy the source row
• Select the newly created target row, right click and paste special
• Paste as formulas

VBA if required with Rows("1:1") being source and Rows("2:2") being target:

Rows("2:2").Insert Shift:=xlDown, CopyOrigin:=xlFormatFromLeftOrAbove
Rows("2:2").Clear

Rows("1:1").Copy
Rows("2:2").PasteSpecial Paste:=xlPasteFormulas, Operation:=xlNone

RFC 6266 describes the “Use of the Content-Disposition Header Field in the Hypertext Transfer Protocol (HTTP)”. Quoting from that:

6. Internationalization Considerations

The “filename*” parameter (Section 4.3), using the encoding defined in [RFC5987], allows the server to transmit characters outside the ISO-8859-1 character set, and also to optionally specify the language in use.

And in their examples section:

This example is the same as the one above, but adding the "filename" parameter for compatibility with user agents not implementing RFC 5987:

Content-Disposition: attachment;
                     filename="EURO rates";
                     filename*=utf-8''%e2%82%ac%20rates

Note: Those user agents that do not support the RFC 5987 encoding ignore “filename*” when it occurs after “filename”.

In Appendix D there is also a long list of suggestions to increase interoperability. It also points at a site which compares implementations. Current all-pass tests suitable for common file names include:

• attwithisofnplain: plain ISO-8859-1 file name with double quotes and without encoding. This requires a file name which is all ISO-8859-1 and does not contain percent signs, at least not in front of hex digits.
• attfnboth: two parameters in the order described above. Should work for most file names on most browsers, although IE8 will use the “filename” parameter.

That RFC 5987 in turn references RFC 2231, which describes the actual format. 2231 is primarily for mail, and 5987 tells us what parts may be used for HTTP headers as well. Don't confuse this with MIME headers used inside a multipart/form-data HTTP body, which is governed by RFC 2388 (section 4.4 in particular) and the HTML 5 draft.

In your script, this part:

document.getElementById('Noite')

must be returning null and you are also attempting to set the display property to an invalid value. There are a couple of possible reasons for this first part to be null.

1. You are running the script too early before the document has been loaded and thus the Noite item can't be found.

2. There is no Noite item in your HTML.

I should point out that your use of document.write() in this case code probably signifies a problem. If the document has already loaded, then a new document.write() will clear the old content and start a new fresh document so no Noite item would be found.

If your document has not yet been loaded and thus you're doing document.write() inline to add HTML inline to the current document, then your document has not yet been fully loaded so that's probably why it can't find the Noite item.

The solution is probably to put this part of your script at the very end of your document so everything before it has already been loaded. So move this to the end of your body:

document.getElementById('Noite').style.display='block';

And, make sure that there are no document.write() statements in javascript after the document has been loaded (because they will clear the previous document and start a new one).

In addition, setting the display property to "display" doesn't make sense to me. The valid options for that are "block", "inline", "none", "table", etc... I'm not aware of any option named "display" for that style property. See here for valid options for teh display property.

You can see the fixed code work here in this demo: http://jsfiddle.net/jfriend00/yVJY4/. That jsFiddle is configured to have the javascript placed at the end of the document body so it runs after the document has been loaded.

P.S. I should point out that your lack of braces for your if statements and your inclusion of multiple statements on the same line makes your code very misleading and unclear.

I'm having a really hard time figuring out what you're asking, but here's a cleaned up version of your code that works which you can also see working here: http://jsfiddle.net/jfriend00/QCxwr/. Here's a list of the changes I made:

1. The script is located in the body, but after the content that it is referencing.
2. I've added var declarations to your variables (a good habit to always use).
3. The if statement was changed into an if/else which is a lot more efficient and more self-documenting as to what you're doing.
4. I've added braces for every if statement so it absolutely clear which statements are part of the if/else and which are not.
5. I've properly closed the </dd> tag you were inserting.
6. I've changed style.display = ''; to style.display = 'block';.
7. I've added semicolons at the end of every statement (another good habit to follow).

The code:

<div id="Night" style="display: none;">
    <img src="Img/night.png" style="position: fixed; top: 0px; left: 5%; height: auto; width: 100%; z-index: -2147483640;">
    <img src="Img/moon.gif" style="position: fixed; top: 0px; left: 5%; height: 100%; width: auto; z-index: -2147483639;">
</div>    
<script>
document.write("<dl><dd>");
var day = new Date();
var hr = day.getHours();
if (hr == 0) {
    document.write("Meia-noite!<br>Já é amanhã!");
} else if (hr <=5 ) {
    document.write("&nbsp;&nbsp;Você não<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;devia<br>&nbsp;&nbsp;&nbsp;&nbsp;estar<br>dormindo?");
} else if (hr <= 11) {         
    document.write("Bom dia!");
} else if (hr == 12) {
    document.write("&nbsp;&nbsp;&nbsp;&nbsp;Vamos<br>&nbsp;almoçar?");
} else if (hr <= 17) {
    document.write("Boa Tarde");
} else if (hr <= 19) {
    document.write("&nbsp;Bom final<br>&nbsp;de tarde!");
} else if (hr == 20) {
    document.write("&nbsp;Boa Noite"); 
    document.getElementById('Noite').style.display='block';
} else if (hr == 21) {
    document.write("&nbsp;Boa Noite"); 
    document.getElementById('Noite').style.display='none';
} else if (hr == 22) {
    document.write("&nbsp;Boa Noite");
} else if (hr == 23) {
    document.write("Ó Meu! Já é quase meia-noite!");
}
document.write("</dl></dd>");
</script>

Working Solution

Step 1: Create Cors middleware

php artisan make:middleware Cors

Step 2: Set header in Cors middleware inside handle function

return $next($request)
        ->header('Access-Control-Allow-Origin', '*')
        ->header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS');

Step 3: Add Cors class in app/Http/Kernel.php

protected $routeMiddleware = [
    ....
    'cors' => \App\Http\Middleware\Cors::class,
];

Step 4: Replace mapApiRoutes in app/providers/routeServiceProvider.php

Route::prefix('api')
         ->middleware(['api', 'cors'])
         ->namespace($this->namespace)
         ->group(base_path('routes/api.php'));

Step 5: Add your routes in routes/api.php

Route::post('example', 'controllerName@functionName')->name('example');

In the file: $your_eclipse_installation\configuration.settings\org.eclipse.core.net.prefs

you need the option: systemProxiesEnabled=true

You can set it also by the Eclipse GUI: Go to Window -> Preferences -> General -> Network Connections Change the provider to "Native"

The first way is working even if your Eclipse is broken due to wrong configuration attempts.

You could use a test runner that would do this for you. nose is very good for example. When run, it will find tests in the current tree and run them.

Updated:

Here's some code from my pre-nose days. You probably don't want the explicit list of module names, but maybe the rest will be useful to you.

testmodules = [
    'cogapp.test_makefiles',
    'cogapp.test_whiteutils',
    'cogapp.test_cogapp',
    ]

suite = unittest.TestSuite()

for t in testmodules:
    try:
        # If the module defines a suite() function, call it to get the suite.
        mod = __import__(t, globals(), locals(), ['suite'])
        suitefn = getattr(mod, 'suite')
        suite.addTest(suitefn())
    except (ImportError, AttributeError):
        # else, just load all the test cases from the module.
        suite.addTest(unittest.defaultTestLoader.loadTestsFromName(t))

unittest.TextTestRunner().run(suite)

SELECT @variable1 = col1, @variable2 = col2
FROM table1

Hope I'm not going offtopic on my first post, but I'd like to expand a little on the casting of integer to string as some respondents appear to have it wrong.

Because the expression in this query uses an arithmetic operator (the plus symbol +), MySQL will convert any strings in the expression to numbers.

To demonstrate, the following will produce the result 6:

SELECT ' 05.05 '+'.95';

String concatenation in MySQL requires the CONCAT() function so there is no ambiguity here and MySQL converts the strings to floats and adds them together.

I actually think the reason the initial query wasn't working is most likely because the $points variable was not in fact set to the user's current points. It was either set to zero, or was unset: MySQL will cast an empty string to zero. For illustration, the following will return 0:

SELECT ABS('');

Like I said, I hope I'm not being too off-topic. I agree that Daan and Tomas have the best solutions for this particular problem.

If you check the API for List you'll notice it says:

Interface List<E>

Being an interface means it cannot be instantiated (no new List() is possible).

If you check that link, you'll find some classes that implement List:

All Known Implementing Classes:

AbstractList, AbstractSequentialList, ArrayList, AttributeList, CopyOnWriteArrayList, LinkedList, RoleList, RoleUnresolvedList, Stack, Vector

Those can be instantiated. Use their links to know more about them, I.E: to know which fits better your needs.

The 3 most commonly used ones probably are:

 List<String> supplierNames1 = new ArrayList<String>();
 List<String> supplierNames2 = new LinkedList<String>();
 List<String> supplierNames3 = new Vector<String>();

Bonus:
You can also instantiate it with values, in an easier way, using the Arrays class, as follows:

List<String> supplierNames = Arrays.asList("sup1", "sup2", "sup3");
System.out.println(supplierNames.get(1));

But note you are not allowed to add more elements to that list, as it's fixed-size.

Error parsing XML: unbound prefix

Resource '/playteddy/res' does not exist.

I got the above two errors and finally I solved it.

Right click your project -> properties -> java build path -> googleadmobadsdk (select and put it top), then you run and problem solved. It is solved my runtime error.

Try CountA:

Dim myArray(1 to 10) as String
Dim arrayCount as String
arrayCount = Application.CountA(myArray)
Debug.Print arrayCount

first, check that who uses port 8080.

• telnet localhost 8080
• use browser to open http://localhost:8080

if the port 8080 is in use, change the listening port to 8181.

if you use IDEA, modify start configuration, Run-> Edit Configuration enter image description here

if you use mvn spring-boot, then use the command:

mvn spring-boot:run -Dserver.port=8181

if you use java -jar, then use the command:

java -jar xxxx.jar --server.port=8181

type

cmd.exe /k cd c:/

in a text file and save as cmd.bat Clicking this file does the trick. You can pin it to the start menu as well.

To start in a partitioned drive (e.g. D), use

cmd.exe /k d:

For android version 5.0 & above

try the Elevation for other views..

android:elevation="10dp"

For Buttons,

android:stateListAnimator="@anim/button_state_list_animator"

button_state_list_animator.xml - https://android.googlesource.com/platform/frameworks/base/+/master/core/res/res/anim/button_state_list_anim_material.xml

below 5.0 version,

For all views,

 android:background="@android:drawable/dialog_holo_light_frame"

My output:

Use the following code fragment to hide the form on button click.

document.getElementById("your form id").style.display="none";

And the following code to display it:

document.getElementById("your form id").style.display="block";

Or you can use the same function for both purposes:

function asd(a)
{
    if(a==1)
        document.getElementById("asd").style.display="none";
    else
        document.getElementById("asd").style.display="block";
}

And the HTML:

<form id="asd">form </form>
<button onclick="asd(1)">Hide</button>
<button onclick="asd(2)">Show</button>

Easiest way

The most trivial way to download a binary file from an FTP server using .NET framework is using WebClient.DownloadFile:

WebClient client = new WebClient();
client.Credentials = new NetworkCredential("username", "password");
client.DownloadFile(
    "ftp://ftp.example.com/remote/path/file.zip", @"C:\local\path\file.zip");

Advanced options

Use FtpWebRequest, only if you need a greater control, that WebClient does not offer (like TLS/SSL encryption, progress monitoring, ascii/text transfer mode, resuming transfers, etc). Easy way is to just copy an FTP response stream to FileStream using Stream.CopyTo:

FtpWebRequest request =
    (FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.DownloadFile;

using (Stream ftpStream = request.GetResponse().GetResponseStream())
using (Stream fileStream = File.Create(@"C:\local\path\file.zip"))
{
    ftpStream.CopyTo(fileStream);
}

Progress monitoring

If you need to monitor a download progress, you have to copy the contents by chunks yourself:

FtpWebRequest request =
    (FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.DownloadFile;

using (Stream ftpStream = request.GetResponse().GetResponseStream())
using (Stream fileStream = File.Create(@"C:\local\path\file.zip"))
{
    byte[] buffer = new byte[10240];
    int read;
    while ((read = ftpStream.Read(buffer, 0, buffer.Length)) > 0)
    {
        fileStream.Write(buffer, 0, read);
        Console.WriteLine("Downloaded {0} bytes", fileStream.Position);
    }
}

For GUI progress (WinForms ProgressBar), see:
FtpWebRequest FTP download with ProgressBar

Downloading folder

If you want to download all files from a remote folder, see
C# Download all files and subdirectories through FTP.

Assign the response to a value and test the attributes of it. These should tell you something useful.

response = requests.post(url,params=data,headers=headers)
response.status_code
response.text

• status_code should just reconfirm the code you were given before, of course

The first one is invalid syntax. You cannot have object properties inside a plain array. The second one is right although it is not strict JSON. It's a relaxed form of JSON wherein quotes in string keys are omitted.

This tutorial by Patrick Hunlock, may help to learn about JSON and this site may help to validate JSON.
