A way that often works well for handling this kind of situation is to not explicitly check if the variable exists but just go ahead and wrap the first usage of the possibly non-existing variable in a try/except NameError:

# Search for entry.
for x in y:
  if x == 3:
    found = x

# Work with found entry.
try:
  print('Found: {0}'.format(found))
except NameError:
  print('Not found')
else:
  # Handle rest of Found case here
  ...

In addition to the accepted answer. You can use a lambda instead of regex:

from bs4 import BeautifulSoup

html = """<p>test python</p>"""

soup = BeautifulSoup(html, "html.parser")

print(soup(text="python"))
print(soup(text=lambda t: "python" in t))

Output:

[]
['test python']

If manually formatting JSON, there is a very handy validator here: jsonlint.com

Use double quotes instead of single quotes:

Invalid:

{
    'project': 'a2ab6ef4-1a8c-40cd-b561-2112b6baffd6',
    'franchise': '110bcca5-cc74-416a-9e2a-f90a8c5f63a0'
}

Valid:

{
    "project": "a2ab6ef4-1a8c-40cd-b561-2112b6baffd6",
    "franchise": "18e899f6-dd71-41b7-8c45-5dc0919679ef"
}

I solved a similar problem. SVN client gave me an error:

"svn: E200002: Failed to create new lock."

I tried everything including "Cleanup" and "Still Lock" but with no success. Then I solved the problem simply, I went to my svn server and deleted the locks folder:

at "c:/svn/my_repository/locks"

It turned out that there are broken files in it.

The same way -- e.g. if you have an 8-bit char, 7 bits can be used for magnitude and 1 for sign. So an unsigned char might range from 0 to 255, whilst a signed char might range from -128 to 127 (for example).

Can you just just some   ?

<div style="text-align: center"> 
    <asp:Button ID="btnSubmit" runat="server" Text="Submit" Width="89px" OnClick="btnSubmit_Click" />
    &nbsp;&nbsp;
    <asp:Button ID="btnClear" runat="server" Text="Clear" Width="89px" OnClick="btnClear_Click" />
</div>

Only one suggestion:-

Read SOA Concepts, Technology and Design by Thomas Erl.

It has very beautifully given the details about SOA in plain English and with case studies.

If you don't mind using lodash try out https://github.com/rockabox/ng-lodash it wraps lodash completely so it is the only dependency and you don't need to load any other script files such as lodash.

Lodash is completely off of the window scope and no "hoping" that it's been loaded prior to your module.

Command

find my_directory/ -maxdepth 1 -printf "%P\n" | tar -cvf my_archive.tar -C my_directory/ -T -

This creates a standard archive file. Standard in a way that files and dirs you want to pack are in the root of the archive. There are no extra special files as '.' and dirs as ./ before each './file'.
Trying so many solutions which are already here with only one successfully, seems to me that using find or possibly other commands like ls -A -1 on the left side of the pipe (-1 as 'one', not -l as 'L') is the only way to achieve above goal.

If tar file is further processed, or delivered to someone as a product of my work, then I don't want to have some weirdness there.

Arguments description

-maxdepth 1
Descend at most 1 level - No recursing.
-printf
print format on the standard output
%P File's name with the name of the starting-point under which it was found removed.
\n Newline
printf does not add a newline at the end of the string. It must be added here

tar:
-C DIR, --directory=DIR
change to directory DIR

-T FILE, --files-from=FILE
get names to extract or create from FILE
-
that FILE from above is the standard input, from the pipe

Comments on other solutions.

The same result might be achieved using solution described by @aross.
The difference with the solution here is in that which tool is doing the recursing. If you leave the job to find, every filepath name, goes through the pipe. It also sends all directory names, which tar with --no-recursion ignores or adds as empty ones followed by all files in each directory. If there was unexpected output as errors in file read from find, tar would not know or care what's going on.
But with further checks, like processing error stream from find, it might be a good solution where many options and filters on files are required.
I prefer to leave the recursing on tar, it does seem simpler and as such more stable solution.
With my complicated directory structure, I feel more confident the archive is complete when tar will not report an error.

Another solution using find proposed by @serendrewpity seems to be fine, but it fails on filenames with spaces. Difference is that output from find supplied by $() sub-shell is space-divided. It might be possible to add quotes using printf, but it would further complicate the statement.

There is no reason to cd into the my_directory and then back, while using ../my_archive.tar for tar path, because TAR has -C DIR, --directory=DIR command which is there just for this purpose.

Using . (dot) will include dots

Using * will let shell supply the input file list. It might be possible using shell options to include dot files. But it's complicated. The command must be executed in shell which allows that. Enabling and disabling must be done before and after tar command. And it will fail if root dir of future archive contains too many files.

That last point also applies to all those solutions which are not using pipe.

Most of solutions are creating a dir inside which are the files and dirs. That is barely ever desired.

You can delete files and folders recursively like this:

void deleteRecursive(File fileOrDirectory) {
    if (fileOrDirectory.isDirectory())
        for (File child : fileOrDirectory.listFiles())
            deleteRecursive(child);

    fileOrDirectory.delete();
}

STATIC_ROOT

The absolute path to the directory where ./manage.py collectstatic will collect static files for deployment. Example: STATIC_ROOT="/var/www/example.com/static/"

now the command ./manage.py collectstatic will copy all the static files(ie in static folder in your apps, static files in all paths) to the directory /var/www/example.com/static/. now you only need to serve this directory on apache or nginx..etc.

STATIC_URL

The URL of which the static files in STATIC_ROOT directory are served(by Apache or nginx..etc). Example: /static/ or http://static.example.com/

If you set STATIC_URL = 'http://static.example.com/', then you must serve the STATIC_ROOT folder (ie "/var/www/example.com/static/") by apache or nginx at url 'http://static.example.com/'(so that you can refer the static file '/var/www/example.com/static/jquery.js' with 'http://static.example.com/jquery.js')

Now in your django-templates, you can refer it by:

{% load static %}
<script src="{% static "jquery.js" %}"></script>

which will render:

<script src="http://static.example.com/jquery.js"></script>

If you have SQL Server 2012:

If your date parts are integers then you can use DATEFROMPARTS function.

SELECT DATENAME( dw, DATEFROMPARTS( @Year, @Month, @Day ) )

If your date parts are strings, then you can use the CONCAT function.

SELECT DATENAME( dw, CONVERT( date, CONCAT( @Day, '/' , @Month, '/', @Year ), 103 ) )

ArrayList<Matrices> list = new ArrayList<Matrices>();
list.add( new Matrices(1,1,10) );
list.add( new Matrices(1,2,20) );

Use the GetInt method.

reader.GetInt32(3);

NSMutableArray *objMyObject = [NSMutableArray arrayWithArray:[self reverseArray:objArrayToBeReversed]];

// Function reverseArray 
-(NSArray *) reverseArray : (NSArray *) myArray {   
    return [[myArray reverseObjectEnumerator] allObjects];
}

This seems to work:

def sanitize_utf8(string)
  return nil if string.nil?
  return string if string.valid_encoding?
  string.chars.select { |c| c.valid_encoding? }.join
end

i had a similar situation and i used the below code for getting this worked..

Aspose.Cells.LoadOptions loadOptions = new Aspose.Cells.LoadOptions(Aspose.Cells.LoadFormat.CSV);

Workbook workbook = new Workbook(fstream, loadOptions);

Worksheet worksheet = workbook.Worksheets[0];

dt = worksheet.Cells.ExportDataTable(0, 0, worksheet.Cells.MaxDisplayRange.RowCount, worksheet.Cells.MaxDisplayRange.ColumnCount, true);

DataTable dtCloned = dt.Clone();
ArrayList myAL = new ArrayList();

foreach (DataColumn column in dtCloned.Columns)
{
    if (column.DataType == Type.GetType("System.DateTime"))
    {
        column.DataType = typeof(String);
        myAL.Add(column.ColumnName);
    }
}


foreach (DataRow row in dt.Rows)
{
    dtCloned.ImportRow(row);
}



foreach (string colName in myAL)
{
    dtCloned.Columns[colName].Convert(val => DateTime.Parse(Convert.ToString(val)).ToString("MMMM dd, yyyy"));
}


/*******************************/

public static class MyExtension

    public static void Convert<T>(this DataColumn column, Func<object, T> conversion)
    {
        foreach (DataRow row in column.Table.Rows)
        {
            row[column] = conversion(row[column]);
        }
    }
}

Hope this helps some1 thx_joxin

I find the following code to be much simpler than anything else:

function setCookie(name,value,days) {
    var expires = "";
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days*24*60*60*1000));
        expires = "; expires=" + date.toUTCString();
    }
    document.cookie = name + "=" + (value || "")  + expires + "; path=/";
}
function getCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}
function eraseCookie(name) {   
    document.cookie = name +'=; Path=/; Expires=Thu, 01 Jan 1970 00:00:01 GMT;';
}

Now, calling functions

setCookie('ppkcookie','testcookie',7);

var x = getCookie('ppkcookie');
if (x) {
    [do something with x]
}

I think the "X" argument of regr.fit needs to be a matrix, so the following should work.

regr = LinearRegression()
regr.fit(df2.iloc[1:1000, [5]].values, df2.iloc[1:1000, 2].values)

In a nutshell, three easy rules to remember PECS:

1. Use the <? extends T> wildcard if you need to retrieve object of type T from a collection.
2. Use the <? super T> wildcard if you need to put objects of type T in a collection.
3. If you need to satisfy both things, well, don’t use any wildcard. As simple as that.

Personally, I think the icons generated by the Google Charts API look great and are easy to customise dynamically.

In the case of a non blocking socket that has no data available, recv will throw the socket.error exception and the value of the exception will have the errno of either EAGAIN or EWOULDBLOCK. Example:

import sys
import socket
import fcntl, os
import errno
from time import sleep

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('127.0.0.1',9999))
fcntl.fcntl(s, fcntl.F_SETFL, os.O_NONBLOCK)

while True:
    try:
        msg = s.recv(4096)
    except socket.error, e:
        err = e.args[0]
        if err == errno.EAGAIN or err == errno.EWOULDBLOCK:
            sleep(1)
            print 'No data available'
            continue
        else:
            # a "real" error occurred
            print e
            sys.exit(1)
    else:
        # got a message, do something :)

The situation is a little different in the case where you've enabled non-blocking behavior via a time out with socket.settimeout(n) or socket.setblocking(False). In this case a socket.error is stil raised, but in the case of a time out, the accompanying value of the exception is always a string set to 'timed out'. So, to handle this case you can do:

import sys
import socket
from time import sleep

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('127.0.0.1',9999))
s.settimeout(2)

while True:
    try:
        msg = s.recv(4096)
    except socket.timeout, e:
        err = e.args[0]
        # this next if/else is a bit redundant, but illustrates how the
        # timeout exception is setup
        if err == 'timed out':
            sleep(1)
            print 'recv timed out, retry later'
            continue
        else:
            print e
            sys.exit(1)
    except socket.error, e:
        # Something else happened, handle error, exit, etc.
        print e
        sys.exit(1)
    else:
        if len(msg) == 0:
            print 'orderly shutdown on server end'
            sys.exit(0)
        else:
            # got a message do something :)

As indicated in the comments, this is also a more portable solution since it doesn't depend on OS specific functionality to put the socket into non-blockng mode.

See recv(2) and python socket for more details.

It depends on what you want to do.

ref: http://www.csharp-examples.net/get-files-from-directory/

This will bring back ALL the files in the specified directory

string[] fileArray = Directory.GetFiles(@"c:\Dir\");

This will bring back ALL the files in the specified directory with a certain extension

string[] fileArray = Directory.GetFiles(@"c:\Dir\", "*.jpg");

This will bring back ALL the files in the specified directory AS WELL AS all subdirectories with a certain extension

string[] fileArray = Directory.GetFiles(@"c:\Dir\", "*.jpg", SearchOption.AllDirectories);

Hope this helps

Summary of all answers (Advantages & Disadvantages)

For single recyclerview

you can use it inside Coordinator layout.

Advantage - it will not load entire recyclerview items. So smooth loading.

Disadvantage - you can't load two recyclerview inside Coordinator layout - it produce scrolling problems

reference - https://stackoverflow.com/a/33143512/3879847

For multiple recylerview with minimum rows

you can load inside NestedScrollView

Advantage - it will scroll smoothly

Disadvantage - It load all rows of recyclerview so your activity open with delay

reference - https://stackoverflow.com/a/33143512/3879847

For multiple recylerview with large rows(more than 100)

You must go with recyclerview.

Advantage - Scroll smoothly, load smoothly

Disadvantage - You need to write more code and logic

Load each recylerview inside main recyclerview with help of multi-viewholders

ex:

MainRecyclerview

-ChildRecyclerview1 (ViewHolder1)

-ChildRecyclerview2 (ViewHolder2)

-ChildRecyclerview3 (ViewHolder3) 

-Any other layout   (ViewHolder4)

Reference for multi-viewHolder - https://stackoverflow.com/a/26245463/3879847

The following commands worked for me:

git push origin :old-name-of-branch-on-github
git branch -m old-name-of-branch-on-github new-name-for-branch-you-want
git push origin new-name-for-branch-you-want

I think this is because you are using client software and not the server.

• mysql is client
• mysqld is the server

Try: sudo service mysqld start

To check that service is running use: ps -ef | grep mysql | grep -v grep.

Uninstalling:

sudo apt-get purge mysql-server
sudo apt-get autoremove
sudo apt-get autoclean

Re-Installing:

sudo apt-get update
sudo apt-get install mysql-server

Backup entire folder before doing this:

sudo rm /etc/apt/apt.conf.d/50unattended-upgrades*
sudo apt-get update
sudo apt-get upgrade

The code below will work just fine in all browsers:

<button onClick="location.href = 'http://www.google.com'">Go to Google</button>

if you use nginx

# skip favicon.ico
#
location = /favicon.ico {
    access_log off;
    return 204;
}

SELECT
   Q.DateInQuarter,
   D.[Year],
   Quarter = D.Year + '-Q'
      + Convert(varchar(1), ((Q.DateInQuarter % 10000 - 100) / 300 + 1))
FROM
   dbo.QuarterDates Q
   CROSS APPLY (
      VALUES (Convert(varchar(4), Q.DateInQuarter / 10000))
   ) D ([Year])
;

Just install:

npm install --save-dev @babel/plugin-transform-runtime

and add it to the plugins array of Babel.

I think you have to define the timestamp column like this

CREATE TABLE t1 
(
    ts TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

See here

The functions need to be defined before being used. There is no mechanism is sh to pre-declare functions, but a common technique is to do something like:

main() {
  case "$choice" in
    true)  process_install;;
    false) process_exit;;
  esac
}

process_install()
{
  commands...
  commands...
}

process_exit()
{
  commands...
  commands...
}

main()

1. Open xls file with a hex editor.
2. Search for DPB
3. Replace DPB to DPx
4. Save file.
5. Open file in Excel.
6. Click "Yes" if you get any message box.
7. Set new password from VBA Project Properties.
8. Close and open again file, then type your new password to unprotect.

Check http://blog.getspool.com/396/best-vba-password-recovery-cracker-tool-remove/

There are some moments where finding a quick solution is great. But if you can avoid lowing passwords restrictions, it can keep you from having big headache in future.

Next link is from the official documentation https://dev.mysql.com/doc/refman/5.6/en/validate-password.html, where they expose an example exactly like your one, and they solve it.

The only one problem you have is that your password is not strong enough to satisfy the actual minimum policy (not recommended to remove). So you can try different passwords as you can see in the example.

if you are using localhost database, try port 3306

Or this will work too the same way but without a save as choice:

Besides the redundant ) this expression will always be true because currentStatus will always match one of these two conditions:

currentStatus !== 'open' || currentStatus !== 'reopen'

perhaps you mean one of

!(currentStatus === 'open' || currentStatus === 'reopen')
(currentStatus !== 'open' && currentStatus !== 'reopen')

Building on top of Tomas's answer, this is the best approach of finding the location tap position as an integer I found:

adb shell getevent -l | grep ABS_MT_POSITION --line-buffered | awk '{a = substr($0,54,8); sub(/^0+/, "", a); b = sprintf("0x%s",a); printf("%d\n",strtonum(b))}'

Use adb shell getevent -l to get a list of events, the using grep for ABS_MT_POSITION (gets the line with touch events in hex) and finally use awk to get the relevant hex values, strip them of zeros and convert hex to integer. This continuously prints the x and y coordinates in the terminal only when you press on the device.

You can then use this adb shell command to send the command:

adb shell input tap x y

I'd guess that Remove and Substring would tie for first place, since they both slurp up a fixed-size portion of the string, whereas TrimStart does a scan from the left with a test on each character and then has to perform exactly the same work as the other two methods. Seriously, though, this is splitting hairs.

Smoke Testing:-

Smoke test is scripted, i.e you have either manual test cases or automated scripts for it.

Sanity Testing:-

Sanity tests are mostly non scripted.

Apparently it does not and I didn't quite expect it would. HOWEVER Ivan brings up a good possibility that has escaped Android people.

What is the purpose of an emulator? to EMULATE, right? I don't see why for testing purposes -provided the tester understands the limitations- the emulator might not add a Wifi emulator.

It could for example emulate WiFi access by using the underlying internet connection of the host. Obviously testing WPA/WEP differencess would not make sense but at least it could toggle access via WiFi.

Or some sort of emulator plugin where there would be a base WiFi emulator that would emulate WiFi access via the underlying connection but then via configuration it could emulate WPA/WEP by providing a list of fake WiFi networks and their corresponding fake passwords that would be matched against a configurable list of credentials.

After all the idea is to do initial testing on the emulator and then move on to the actual device.

There is another place where the TNS location is stored: If you're using Windows, open regedit and navigate to My HKEY Local Machine/Software/ORACLE/KEY_OraClient10_home1 where KEY_OraClient10_home1 is your Oracle home. If there is a string entry called TNS_ADMIN, then the value of that entry will point to the TNS file that Oracle is using on your computer.

If Khanh TO's solution caused UI issues for you (like it did for me) try using $timeout to not update the attribute until it has been unchanged for 500ms.

var oldWidth = window.innerWidth;
$(window).on('resize.doResize', function () {
    var newWidth = window.innerWidth,
        updateStuffTimer;

    if (newWidth !== oldWidth) {
        $timeout.cancel(updateStuffTimer);
    }

    updateStuffTimer = $timeout(function() {
         updateStuff(newWidth); // Update the attribute based on window.innerWidth
    }, 500);
});

$scope.$on('$destroy',function (){
    $(window).off('resize.doResize'); // remove the handler added earlier
});

I would also like to add something here that if you load desired form that contain tooltip controll before the program's run then tool tip control on that form will not work as described below...

        Application.SetCompatibleTextRenderingDefault(false);
        objfrmmain = new Frm_Main();
        Showtop();//this is procedure in program.cs to load an other form, so if that contain's tool tip control then it will not work
        Application.Run(objfrmmain);


    }

so I solved this problem by puting following code in Fram_main_load event procedure like this

    private void Frm_Main_Load(object sender, EventArgs e)
    {
        Program.Showtop();
    }

Even though too much of CLOSE_WAIT connections means there is something wrong with your code in the first and this is accepted not good practice.

You might want to check out: https://github.com/rghose/kill-close-wait-connections

What this script does is send out the ACK which the connection was waiting for.

This is what worked for me.

The first parameter to concatenate should itself be a sequence of arrays to concatenate:

numpy.concatenate((a,b)) # Note the extra parentheses.

I think that you could use a POST or PATCH method to handle this since they typically design for this.

• Using a POST method is typically used to add an element when used on list resource but you can also support several actions for this method. See this answer: How to Update a REST Resource Collection. You can also support different representation formats for the input (if they correspond to an array or a single elements).

  In the case, it's not necessary to define your format to describe the update.

• Using a PATCH method is also suitable since corresponding requests correspond to a partial update. According to RFC5789 (http://tools.ietf.org/html/rfc5789):

  Several applications extending the Hypertext Transfer Protocol (HTTP) require a feature to do partial resource modification. The existing HTTP PUT method only allows a complete replacement of a document. This proposal adds a new HTTP method, PATCH, to modify an existing HTTP resource.

  In the case, you have to define your format to describe the partial update.

I think that in this case, POST and PATCH are quite similar since you don't really need to describe the operation to do for each element. I would say that it depends on the format of the representation to send.

The case of PUT is a bit less clear. In fact, when using a method PUT, you should provide the whole list. As a matter of fact, the provided representation in the request will be in replacement of the list resource one.

You can have two options regarding the resource paths.

• Using the resource path for doc list

In this case, you need to explicitely provide the link of docs with a binder in the representation you provide in the request.

Here is a sample route for this /docs.

The content of such approach could be for method POST:

[
    { "doc_number": 1, "binder": 4, (other fields in the case of creation) },
    { "doc_number": 2, "binder": 4, (other fields in the case of creation) },
    { "doc_number": 3, "binder": 5, (other fields in the case of creation) },
    (...)
]

• Using sub resource path of binder element

In addition you could also consider to leverage sub routes to describe the link between docs and binders. The hints regarding the association between a doc and a binder doesn't have now to be specified within the request content.

Here is a sample route for this /binder/{binderId}/docs. In this case, sending a list of docs with a method POST or PATCH will attach docs to the binder with identifier binderId after having created the doc if it doesn't exist.

The content of such approach could be for method POST:

[
    { "doc_number": 1, (other fields in the case of creation) },
    { "doc_number": 2, (other fields in the case of creation) },
    { "doc_number": 3, (other fields in the case of creation) },
    (...)
]

Regarding the response, it's up to you to define the level of response and the errors to return. I see two levels: the status level (global level) and the payload level (thinner level). It's also up to you to define if all the inserts / updates corresponding to your request must be atomic or not.

• Atomic

In this case, you can leverage the HTTP status. If everything goes well, you get a status 200. If not, another status like 400 if the provided data aren't correct (for example binder id not valid) or something else.

• Non atomic

In this case, a status 200 will be returned and it's up to the response representation to describe what was done and where errors eventually occur. ElasticSearch has an endpoint in its REST API for bulk update. This could give you some ideas at this level: http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/bulk.html.

• Asynchronous

You can also implement an asynchronous processing to handle the provided data. In this case, the HTTP status returns will be 202. The client needs to pull an additional resource to see what happens.

Before finishing, I also would want to notice that the OData specification addresses the issue regarding relations between entities with the feature named navigation links. Perhaps could you have a look at this ;-)

this turns the recursion in to a loop:

def checkNextID(ID):
    global numOfRuns, curRes, lastResult
    while ID < lastResult:
        try:
            numOfRuns += 1
            if numOfRuns % 10 == 0:
                time.sleep(3) # sleep every 10 iterations
            if isValid(ID + 8):
                parseHTML(curRes)
                ID = ID + 8
            elif isValid(ID + 18):
                parseHTML(curRes)
                ID = ID + 18
            elif isValid(ID + 7):
                parseHTML(curRes)
                ID = ID + 7
            elif isValid(ID + 17):
                parseHTML(curRes)
                ID = ID + 17
            elif isValid(ID+6):
                parseHTML(curRes)
                ID = ID + 6
            elif isValid(ID + 16):
                parseHTML(curRes)
                ID = ID + 16
            else:
                ID = ID + 1
        except Exception, e:
            print "somethin went wrong: " + str(e)

You need to set the "default value" for the date field to getdate(). Any records inserted into the table will automatically have the insertion date as their value for this field.

The location of the "default value" property is dependent on the version of SQL Server Express you are running, but it should be visible if you select the date field of your table when editing the table.

Looks like you are running afoul of this rule for updating views from Books Online: "INSERT statements must specify values for any columns in the underlying table that do not allow null values and have no DEFAULT definitions."

Definitely Purify! I've used that to analyze some massive code bases (>3,000 kSLOC) and found it to be excellent.

You might like to look at this list at Wikipedia.

By the way, I've found memwatch to be useful. Thanks Johan!

Here is another option for a specific case. :)

If you want to test for a member on an object and want to know if it has been set to something other than:

• ''
• false
• null
• undefined
• 0 ...

then you can use:

var foo = {};
foo.bar = "Yes, this is a proper value!";
if (!!foo.bar) {
    // member is set, do something
}

Firstly, there is an issue with the ADT plugin and Helios which causes lag with looking up Android classes - use Galileo instead (v3.5).

Secondly, the emulators become more resource hungry depending on the version of Android you're developing for. Example, I have a P4 2.4GHz, 1GB RAM PC with Win XP 32-bit and an Android v2.2 emulator takes at least 4-5 minutes to load up. An Android v1.6 emulator on the other hand loads up in less than 1 minute. Remember though that once the emulator is up and running, you can leave it loaded and it will be more responsive than first use.

Also bear in mind that if you give your emulator a 2GB SD card (for example) it will try to create that through virtual memory if there isn't enough physical memory.

location.href = "Pagename.html";

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

This problem happens because IIS does not know about woff and woff2 file mime types.

Solution 1:

Add these lines in your web.config project:

 <system.webServer>
  ...
  </modules>
    <staticContent>
      <remove fileExtension=".woff" />
      <mimeMap fileExtension=".woff" mimeType="application/font-woff" />
      <remove fileExtension=".woff2" />
      <mimeMap fileExtension=".woff2" mimeType="font/woff2" />
    </staticContent>

Solution 2:

On IIS project page:

Step 1: Go to your project IIS home page and double click on MIME Types button:

Step 2: Click on Add button from Actions menu:

Step 3: In the middle of the screen appears a window and in this window you need to add the two lines from solution 1:

You can cut using following ,
-d: delimiter ,-f for fields
\t used for tab separated fields

cut -d$'\t' -f 1-3,7-

You need to use the Scatter chart type instead of Line. That will allow you to define separate X values for each series.

It appears that every object has an overhead of 16 bytes on 32-bit systems (and 24-byte on 64-bit systems).

http://algs4.cs.princeton.edu/14analysis/ is a good source of information. One example among many good ones is the following.

http://www.cs.virginia.edu/kim/publicity/pldi09tutorials/memory-efficient-java-tutorial.pdf is also very informative, for example:

You could use array_map():

function add_quotes($str) {
    return sprintf("'%s'", $str);
}

$csv =  implode(',', array_map('add_quotes', $array));

DEMO

Also note that there is fputcsv if you want to write to a file.

Name your webapp WAR “ROOT.war” or containing folder “ROOT”

As for the meaning of each character described in C Primer Plus, what you expected is an 'correct' answer. It should be true for some computer architectures and compilers, but unfortunately not yours.

I wrote a simple c program to repeat your test, and got that 'correct' answer. I was using Mac OS and gcc.

Also, I am very curious what is the compiler that you were using. :)

Canvas would be a great way to do this, as @pst said above. Check out this answer for a good example:

getPixel from HTML Canvas?

Some code that would serve you specifically as well:

var imgd = context.getImageData(x, y, width, height);
var pix = imgd.data;

for (var i = 0, n = pix.length; i < n; i += 4) {
  console.log pix[i+3]
}

This will go row by row, so you'd need to convert that into an x,y and either convert the for loop to a direct check or run a conditional inside.

Reading your question again, it looks like you want to be able to get the point that the person clicks on. This can be done pretty easily with jquery's click event. Just run the above code inside a click handler as such:

$('el').click(function(e){
   console.log(e.clientX, e.clientY)
}

Those should grab your x and y values.

By declaring one in your AndroidManifest.xml file with the tag (also called static)

<receiver android:name=".YourBrodcastReceiverClass"  android:exported="true">
<intent-filter>
    <!-- The actions you wish to listen to, below is an example -->
    <action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>

You will notice that the broadcast receiver declared above has a property of exported=”true”. This attribute tells the receiver that it can receive broadcasts from outside the scope of the application.
2. Or dynamically by registering an instance with registerReceiver (what is known as context registered)

public abstract Intent registerReceiver (BroadcastReceiver receiver, 
            IntentFilter filter);

public void onReceive(Context context, Intent intent) {
//Implement your logic here
}

There are three ways to send broadcasts:
The sendOrderedBroadcast method, makes sure to send broadcasts to only one receiver at a time. Each broadcast can in turn, pass along data to the one following it, or to stop the propagation of the broadcast to the receivers that follow.
The sendBroadcast is similar to the method mentioned above, with one difference. All broadcast receivers receive the message and do not depend on one another.
The LocalBroadcastManager.sendBroadcast method only sends broadcasts to receivers defined inside your application and does not exceed the scope of your application.

Is there a way to declare first and then initialize an array in C?

There is! but not using the method you described.

You can't initialize with a comma separated list, this is only allowed in the declaration. You can however initialize with...

myArray[0] = 1;
myArray[1] = 2;
...

or

for(int i = 1; i <= SIZE; i++)
{
  myArray[i-1] = i;
}

Thread

Thread represents an actual OS-level thread, with its own stack and kernel resources. (technically, a CLR implementation could use fibers instead, but no existing CLR does this) Thread allows the highest degree of control; you can Abort() or Suspend() or Resume() a thread (though this is a very bad idea), you can observe its state, and you can set thread-level properties like the stack size, apartment state, or culture.

The problem with Thread is that OS threads are costly. Each thread you have consumes a non-trivial amount of memory for its stack, and adds additional CPU overhead as the processor context-switch between threads. Instead, it is better to have a small pool of threads execute your code as work becomes available.

There are times when there is no alternative Thread. If you need to specify the name (for debugging purposes) or the apartment state (to show a UI), you must create your own Thread (note that having multiple UI threads is generally a bad idea). Also, if you want to maintain an object that is owned by a single thread and can only be used by that thread, it is much easier to explicitly create a Thread instance for it so you can easily check whether code trying to use it is running on the correct thread.

ThreadPool

ThreadPool is a wrapper around a pool of threads maintained by the CLR. ThreadPool gives you no control at all; you can submit work to execute at some point, and you can control the size of the pool, but you can't set anything else. You can't even tell when the pool will start running the work you submit to it.

Using ThreadPool avoids the overhead of creating too many threads. However, if you submit too many long-running tasks to the threadpool, it can get full, and later work that you submit can end up waiting for the earlier long-running items to finish. In addition, the ThreadPool offers no way to find out when a work item has been completed (unlike Thread.Join()), nor a way to get the result. Therefore, ThreadPool is best used for short operations where the caller does not need the result.

Task

Finally, the Task class from the Task Parallel Library offers the best of both worlds. Like the ThreadPool, a task does not create its own OS thread. Instead, tasks are executed by a TaskScheduler; the default scheduler simply runs on the ThreadPool.

Unlike the ThreadPool, Task also allows you to find out when it finishes, and (via the generic Task) to return a result. You can call ContinueWith() on an existing Task to make it run more code once the task finishes (if it's already finished, it will run the callback immediately). If the task is generic, ContinueWith() will pass you the task's result, allowing you to run more code that uses it.

You can also synchronously wait for a task to finish by calling Wait() (or, for a generic task, by getting the Result property). Like Thread.Join(), this will block the calling thread until the task finishes. Synchronously waiting for a task is usually bad idea; it prevents the calling thread from doing any other work, and can also lead to deadlocks if the task ends up waiting (even asynchronously) for the current thread.

Since tasks still run on the ThreadPool, they should not be used for long-running operations, since they can still fill up the thread pool and block new work. Instead, Task provides a LongRunning option, which will tell the TaskScheduler to spin up a new thread rather than running on the ThreadPool.

All newer high-level concurrency APIs, including the Parallel.For*() methods, PLINQ, C# 5 await, and modern async methods in the BCL, are all built on Task.

Conclusion

The bottom line is that Task is almost always the best option; it provides a much more powerful API and avoids wasting OS threads.

The only reasons to explicitly create your own Threads in modern code are setting per-thread options, or maintaining a persistent thread that needs to maintain its own identity.

os.path.splitext(), os.rename()

for example:

# renamee is the file getting renamed, pre is the part of file name before extension and ext is current extension
pre, ext = os.path.splitext(renamee)
os.rename(renamee, pre + new_extension)

I had this problem while working with Pycharm and with a database that was originally given to me by another user.

So, this is how I solve it in my case:

1. Closed all tabs in Pycharm that operate with the problematic database.
2. Stop all running processes from the red square botton in the top right corner of Pycharm.
3. Delete the problematic database from the directory.
4. Upload again the original database. And it worked again.

this can be achieved with the css calc() operator

@media screen and (min-width: 480px) {
    body {
        background-color: lightgreen;
        zoom:calc(100% / 480);
    }
}

Similar to @Matthew_Plourde using gsub

However, using a pattern that will trim to zero characters i.e. return "" if the original string is shorter than the number of characters to cut:

cs <- c("foo_bar","bar_foo","apple","beer","so","a")
gsub('.{0,3}$', '', cs)
# [1] "foo_" "bar_" "ap"   "b"    ""    ""

Difference is, {0,3} quantifier indicates 0 to 3 matches, whereas {3} requires exactly 3 matches otherwise no match is found in which case gsub returns the original, unmodified string.

N.B. using {,3} would be equivalent to {0,3}, I simply prefer the latter notation.

See here for more information on regex quantifiers: https://www.regular-expressions.info/refrepeat.html

The name of the array indicates the starting address. Starting address of both namet2 and nameIt2 are different. So the equal to (==) operator checks whether the addresses are the same or not. For comparing two strings, a better way is to use strcmp(), or we can compare character by character using a loop.

There're no packets in TCP API.

There're packets in underlying protocols often, like when TCP is done over IP, which you have no interest in, because they have nothing to do with the user except for very delicate performance optimizations which you are probably not interested in (according to the question's formulation).

If you ask what is a maximum number of bytes you can send() in one API call, then this is implementation and settings dependent. You would usually call send() for chunks of up to several kilobytes, and be always ready for the system to refuse to accept it totally or partially, in which case you will have to manually manage splitting into smaller chunks to feed your data into the TCP send() API.

There's a lot more to abstract classes than default method implementations (such as private state), but as of Java 8, whenever you have the choice of either, you should go with the defender (aka. default) method in the interface.

The constraint on the default method is that it can be implemented only in the terms of calls to other interface methods, with no reference to a particular implementation's state. So the main use case is higher-level and convenience methods.

The good thing about this new feature is that, where before you were forced to use an abstract class for the convenience methods, thus constraining the implementor to single inheritance, now you can have a really clean design with just the interface and a minimum of implementation effort forced on the programmer.

The original motivation to introduce default methods to Java 8 was the desire to extend the Collections Framework interfaces with lambda-oriented methods without breaking any existing implementations. Although this is more relevant to the authors of public libraries, you may find the same feature useful in your project as well. You've got one centralized place where to add new convenience and you don't have to rely on how the rest of the type hierarchy looks.

Quick guide:

• Download Google USB Driver

• Connect your device with Android Debugging enabled to your PC

• Open Device Manager of Windows from System Properties.

• Your device should appear under Other devices listed as something like Android ADB Interface or 'Android Phone' or similar. Right-click that and click on Update Driver Software...

• Select Browse my computer for driver software

• Select Let me pick from a list of device drivers on my computer

• Double-click Show all devices

• Press the Have disk button

• Browse and navigate to [wherever your SDK has been installed]\google-usb_driver and select android_winusb.inf

• Select Android ADB Interface from the list of device types.

• Press the Yes button

• Press the Install button

• Press the Close button

Now you've got the ADB driver set up correctly. Reconnect your device if it doesn't recognize it already.

Since it has not been suggested yet, I'm pretty sure LOAD DATA INFILE is still the fastest way to load data as it disables indexing, inserts all data, and then re-enables the indexes - all in a single request.

Saving the data as a csv should be fairly trivial keeping in mind fputcsv. MyISAM is fastest, but you still get big performance in InnoDB. There are other disadvantages, though so I would go this route if you are inserting a lot of data, and not bother with under 100 rows.

vertical-align applies to the elements being aligned, not their parent element. To vertically align the div's children, do this instead:

div > * {
    vertical-align:middle;  // Align children to middle of line
}

See: http://jsfiddle.net/dfmx123/TFPx8/1186/

NOTE: vertical-align is relative to the current text line, not the full height of the parent div. If you wanted the parent div to be taller and still have the elements vertically centered, set the div's line-height property instead of its height. Follow jsfiddle link above for an example.

This is as simple as this.

window.open('_link is here_', 'name'); 

Function description:

name is a name of the window. Following names are supported:

• _blank - URL is loaded into a new tab. This is default.
• _parent - URL is loaded into the parent frame
• _self - URL replaces the current page
• _top - URL replaces any framesets that may be loaded

I like Stefan’s answer (Sep 11 ’13) but would like to make it a bit stronger:

If the vector ends with a null terminator, you should not use (v.begin(), v.end()): you should use v.data() (or &v[0] for those prior to C++17).

If v does not have a null terminator, you should use (v.begin(), v.end()).

If you use begin() and end() and the vector does have a terminating zero, you’ll end up with a string "abc\0" for example, that is of length 4, but should really be only "abc".

You can use:

Sub returnname(ByVal TableName As String)

MsgBox (Range("Table15").Rows.count)

End Sub

and call the function as below

Sub called()

returnname "Table15"

End Sub

Answer

You can't according to the PHP manual:

Once the cookies have been set, they can be accessed on the next page load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.

This is because cookies are sent in response headers to the browser and the browser must then send them back with the next request. This is why they are only available on the second page load.

Work around

But you can work around it by also setting $_COOKIE when you call setcookie():

if(!isset($_COOKIE['lg'])) {
    setcookie('lg', 'ro');
    $_COOKIE['lg'] = 'ro';
}
echo $_COOKIE['lg'];

The short answer is the iPhone supports H.264 video, High profile and AAC audio, in container formats .mov, .mp4, or MPEG Segment .ts. MPEG Segment files are used for HTTP Live Streaming.

• For maximum compatibility with Android and desktop browsers, use H.264 + AAC in an .mp4 container.
• For extended length videos longer than 10 minutes you must use HTTP Live Streaming, which is H.264 + AAC in a series of small .ts container files (see App Store Review Guidelines rule 2.5.7).

Video

On the iPhone, H.264 is the only game in town. [1]

There are several different feature tiers or "profiles" available in H.264. All modern iPhones (3GS and above) support the High profile. These profiles are basically three different levels of algorithm "tricks" used to compress the video. More tricks give better compression, but require more CPU or dedicated hardware to decode. This is a table that lists the differences between the different profiles.

[1] Interestingly, Apple's own Facetime uses the newer H.265 (HEVC) video codec. However right now (August 2017) there is no Apple-provided library that gives access to a HEVC codec to developers. This is expected to change at some point.

In talking about what video format the iPhone supports, a distinction should be made between what the hardware can support, and what the (much lower) limits are for playback when streaming over a network.

The only data given about hardware video support by Apple about the current generation of iPhones (SE, 6S, 6S Plus, 7, 7 Plus) is that they support

4K [3840x2160] video recording at 30 fps

1080p [1920x1080] HD video recording at 30 fps or 60 fps.

Obviously the phone can play back what it can record, so we can guess that 3840x2160 at 30 fps and 1920x1080 at 60 fps represent design limits of the phone. In addition, the screen size on the 6S Plus and 7 Plus is 1920x1080. So if you're interested in playback on the phone, it doesn't make sense to send over more pixels then the screen can draw.

However, streaming video is a different matter. Since networks are slow and video is huge, it's typical to use lower resolutions, bitrates, and frame rates than the device's theoretical maximum.

The most detailed document giving recommendations for streaming is TN2224 Best Practices for Creating and Deploying HTTP Live Streaming Media for Apple Devices. Figure 3 in that document gives a table of recommended streaming parameters:

This table is from May 2016.

As you can see, Apple recommends the relatively low resolution of 768x432 as the highest recommended resolution for streaming over a cellular network. Of course this is just a recommendation and YMMV.

Audio

The question is about video, but that video generally has one or more audio tracks with it. The iPhone supports a few audio formats, but the most modern and by far most widely used is AAC. The iPhone 7 / 7 Plus, 6S Plus / 6S, SE all support AAC bitrates of 8 to 320 Kbps.

Container

The audio and video tracks go inside a container. The purpose of the container is to combine (interleave) the different tracks together, to store metadata, and to support seeking. The iPhone supports

1. QuickTime .mov,
2. MP4, and
3. MPEG-TS.

The .mov and .mp4 file formats are closely related (.mp4 is in fact based on .mov), however .mp4 is an ISO standard that has much wider support.

As noted above, you have to use MPEG-TS for videos longer than 10 minutes.

In my case new File() doesn't work, it causes a FileNotFoundException when run in a Jenkins pipeline job. The following code solved this, and is even easier in my opinion:

def fileContents = readFile "path/to/file"

I still don't understand this difference completely, but maybe it'll help anyone else with the same trouble. Possibly the exception was caused because new File() creates a file on the system which executes the groovy code, which was a different system than the one that contains the file I wanted to read.

The ESCAPE keyword is used if you need to search for special characters like % and _, which are normally wild cards. If you specify ESCAPE, SQL will search literally for the characters % and _.

Here's a good article with some more examples

SELECT columns FROM table WHERE 
    column LIKE '%[[]SQL Server Driver]%' 

-- or 

SELECT columns FROM table WHERE 
    column LIKE '%\[SQL Server Driver]%' ESCAPE '\'

This should do what you're looking for.

CSS:

html, body {
    height: 100%;
    margin: 0;
}

.gif-container {
  background: url("image.gif") center;
  background-size: cover;

  height: 100%;
}

HTML:

<div class="gif-container"></div>

Nope, BeautifulSoup, by itself, does not support XPath expressions.

An alternative library, lxml, does support XPath 1.0. It has a BeautifulSoup compatible mode where it'll try and parse broken HTML the way Soup does. However, the default lxml HTML parser does just as good a job of parsing broken HTML, and I believe is faster.

Once you've parsed your document into an lxml tree, you can use the .xpath() method to search for elements.

try:
    # Python 2
    from urllib2 import urlopen
except ImportError:
    from urllib.request import urlopen
from lxml import etree

url =  "http://www.example.com/servlet/av/ResultTemplate=AVResult.html"
response = urlopen(url)
htmlparser = etree.HTMLParser()
tree = etree.parse(response, htmlparser)
tree.xpath(xpathselector)

There is also a dedicated lxml.html() module with additional functionality.

Note that in the above example I passed the response object directly to lxml, as having the parser read directly from the stream is more efficient than reading the response into a large string first. To do the same with the requests library, you want to set stream=True and pass in the response.raw object after enabling transparent transport decompression:

import lxml.html
import requests

url =  "http://www.example.com/servlet/av/ResultTemplate=AVResult.html"
response = requests.get(url, stream=True)
response.raw.decode_content = True
tree = lxml.html.parse(response.raw)

Of possible interest to you is the CSS Selector support; the CSSSelector class translates CSS statements into XPath expressions, making your search for td.empformbody that much easier:

from lxml.cssselect import CSSSelector

td_empformbody = CSSSelector('td.empformbody')
for elem in td_empformbody(tree):
    # Do something with these table cells.

Coming full circle: BeautifulSoup itself does have very complete CSS selector support:

for cell in soup.select('table#foobar td.empformbody'):
    # Do something with these table cells.

I had problem with android studio detecting my phone(Acer Liquid Zest 4G), tried restarting android studio, switching back and forth between PTP and MTP, OS was able to detect device normally.

So what I did was, in Developer Options i enabled USB debugging, USB connection is in PTP mode, then from phone manufacturer's site (you can find site for your phone here: https://developer.android.com/studio/run/oem-usb.html), I downloaded USB driver for my phone model, installed driver and android studio was able to detect my phone(there was no need for restart).

I will repeat again, you must have USB Debugging enabled in Developer Options, otherwise it won't work. Hope it helps.

All the answers are outdated and don't work; use the below method.

All apps of a developer:
itms-apps://apps.apple.com/developer/developer-name/developerId

Single app:
itms-apps://itunes.apple.com/app/appId

The volume it's on is mounted noexec.

this prototype:

  int execlp(const char *file, const char *arg, ...);

Says that execlp ìs a variable argument function. It takes 2 const char *. The rest of the arguments, if any, are the additional arguments to hand over to program we want to run - also char * - all these are C strings (and the last argument must be a NULL pointer)

So, the file argument is the path name of an executable file to be executed. arg is the string we want to appear as argv[0] in the executable. By convention, argv[0] is just the file name of the executable, normally it's set to the same as file.

The ... are now the additional arguments to give to the executable.

Say you run this from a commandline/shell:

$ ls

That'd be execlp("ls", "ls", (char *)NULL); Or if you run

$ ls -l /

That'd be execlp("ls", "ls", "-l", "/", (char *)NULL);

So on to execlp("/bin/sh", ..., "ls -l /bin/??", ...);

Here you are going to the shell, /bin/sh , and you're giving the shell a command to execute. That command is "ls -l /bin/??". You can run that manually from a commandline/shell:

 $ ls -l /bin/??

Now, how do you run a shell and tell it to execute a command ? You open up the documentation/man page for your shell and read it.

What you want to run is:

$ /bin/sh -c "ls -l /bin/??"

This becomes

  execlp("/bin/sh","/bin/sh", "-c", "ls -l /bin/??", (char *)NULL);

Side note: The /bin/?? is doing pattern matching, this pattern matching is done by the shell, and it expands to all files under /bin/ with 2 characters. If you simply did

  execlp("ls","ls", "-l", "/bin/??", (char *)NULL);

Probably nothing would happen (unless there's a file actually named /bin/??) as there's no shell that interprets and expands /bin/??

Nick Craver's answer needs to be slightly modified to work on iOS 6 Safari Mobile and should be:

$(window).scroll(function() {
   if($(window).scrollTop() + window.innerHeight == $(document).height()) {
       alert("bottom!");
   }
});

Changing $(window).height() to window.innerHeight should be done because when the address bar is hidden an additional 60px are added to the window's height but using $(window).height() does not reflect this change, while using window.innerHeight does.

Note: The window.innerHeight property also includes the horizontal scrollbar's height (if it is rendered), unlike $(window).height() which will not include the horizontal scrollbar's height. This is not a problem in Mobile Safari, but could cause unexpected behavior in other browsers or future versions of Mobile Safari. Changing == to >= could fix this for most common use cases.

Read more about the window.innerHeight property here

To make certain file types OPEN on your computer, instead of Chrome Downloading...

You have to download the file type once, then right after that download, look at the status bar at the bottom of the browser. Click the arrow next to that file and choose "always open files of this type". DONE.

Now the file type will always OPEN using your default program.

To reset this feature, go to Settings / Advance Settings and under the "Download.." section, there's a button to reset 'all' Auto Downloads

Hope this helps.. :-)

This does what you want, I think:

git log --all --pretty=format: --name-only --diff-filter=D | sort -u

... which I've just taken more-or-less directly from this other answer.

I don't know if there's a 'proper' way to do it, but your snippet is on the right track: just add import foo to foo.py, do inspect.getmembers(foo), and it should work fine.

If anyone still has problem, this is my code.

I have a custom view which is square (width = height) and I want to assign a character to it. onDraw() shows how to get height of character, although I'm not using it. Character will be displayed in the middle of view.

        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        height = this.getMeasuredHeight();
        width = this.getMeasuredWidth();

        setMeasuredDimension(width, width);
    }

    protected void onDraw(Canvas canvas) {
        float mDensity = context.getResources().getDisplayMetrics().density;
        float mScaledDensity = context.getResources().getDisplayMetrics().scaledDensity;

        previewPaint.setAlpha(200);
        previewPaint.setAntiAlias(true);

        Paint previewTextPaint = new Paint();
        previewTextPaint.setColor(Color.WHITE);
        previewTextPaint.setAntiAlias(true);
        previewTextPaint.setTextSize(90 * mScaledDensity);
        previewTextPaint.setShadowLayer(5, 1, 2, Color.argb(255, 87, 87, 87));

        float previewTextWidth = previewTextPaint.measureText(label);
//        float previewTextHeight = previewTextPaint.descent() - previewTextPaint.ascent();
        RectF previewRect = new RectF(0, 0, width, width);

        canvas.drawRoundRect(previewRect, 5 * mDensity, 5 * mDensity, previewPaint);
        canvas.drawText(label, (width - previewTextWidth)/2, previewRect.top - previewTextPaint.ascent(), previewTextPaint);

        super.onDraw(canvas);
    }

    public void setLabel(String label) {

In your settings.py add a root staticfiles directory:

   STATICFILES_DIRS = [
        os.path.join(BASE_DIR, 'static')
        ]

Create /static/images/favicon.ico

Add the favicon to your template(base.html):

{% load static %}
<link rel="shortcut icon" type="image/png" href="{% static 'images/favicon.ico' %}"/>

And create a url redirect in urls.py because browsers look for a favicon in /favicon.ico

from django.contrib.staticfiles.storage import staticfiles_storage
from django.views.generic.base import RedirectView

urlpatterns = [
    ...
    path('favicon.ico', RedirectView.as_view(url=staticfiles_storage.url('images/favicon.ico')))
]

I encountered this insertion performance problem as well. My solution is spawn some go routines to finish the insertion work. In the meantime, SetMaxOpenConns should be given a proper number otherwise too many open connection error would be alerted.

db, _ := sql.open() 
db.SetMaxOpenConns(SOME CONFIG INTEGER NUMBER) 
var wg sync.WaitGroup
for _, query := range queries {
    wg.Add(1)
    go func(msg string) {
        defer wg.Done()
        _, err := db.Exec(msg)
        if err != nil {
            fmt.Println(err)
        }
    }(query)
}
wg.Wait()

The loading speed is much faster for my project. This code snippet just gave an idea how it works. Readers should be able to modify it easily.

Implement the UITextFieldDelegate method like this:

- (BOOL)textFieldShouldReturn:(UITextField *)aTextField
{
    [aTextField resignFirstResponder];
    return YES;
}

If you can't assume that all the strings you process have double quotes you can use something like this:

if string.startswith('"') and string.endswith('"'):
    string = string[1:-1]

Edit:

I'm sure that you just used string as the variable name for exemplification here and in your real code it has a useful name, but I feel obliged to warn you that there is a module named string in the standard libraries. It's not loaded automatically, but if you ever use import string make sure your variable doesn't eclipse it.

An alternative for array_unique() function..

Using Brute force algorithm

//[1] This our array with duplicated items
$matches = ["jorge","melvin","chelsy","melvin","jorge","smith"];
//[2] Container for the new array without any duplicated items
$arr = [];
//[3] get the length of the duplicated array and set it to the var len to be use for for loop
$len = count($matches);
//[4] If matches array key($i) current loop Iteration is not available in
//[4] the array $arr then push the current iteration key value of the matches[$i]
//[4] to the array arr.
for($i=0;$i
if(array_search($matches[$i], $arr) === false){
array_push($arr,$matches[$i]);
}
}
//print the array $arr.
print_r($arr);
//Result: Array
(
[0] => jorge
[1] => melvin
[2] => chelsy
[3] => smith
)

If you have two columns with the same name. One simple way is to manually rename the columns like this:-

df.columns = ['column1', 'column2', 'column3']

Then you can drop via column index as you requested, like this:-

df.drop(df.columns[1], axis=1, inplace=True)

df.column[1] will drop index 1.

Remember axis 1 = columns and axis 0 = rows.

I encountered this error once after omitting this statement from my transaction.

COMMIT TRANSACTION [MyTransactionName]

You need either

• A unique index on Title in BookTitle
• An ISBN column in BookCopy and the FK is on both columns

A foreign key needs to uniquely identify the parent row: you currently have no way to do that because Title is not unique.

src is the first argument to cv2.cvtColor.

The error you are getting is because it is not the right form. cv2.Umat() is functionally equivalent to np.float32(), so your last line of code should read:

gray = cv2.cvtColor(np.float32(imgUMat), cv2.COLOR_RGB2GRAY)

Minizip does have an example programs to demonstrate its usage - the files are called minizip.c and miniunz.c.

• It was released in version 1.1.0-alpha01, so appcompat version should be at least 1.1.0-alpha01. Current latest version is 1.1.0-alpha02, use latest versions for better reliability, see release notes - link.

  implementation 'androidx.appcompat:appcompat:1.1.0-alpha02'

• Use AppCompatTextView/AppCompatButton/AppCompatEditText

• Use app:drawableLeftCompat, app:drawableTopCompat, app:drawableRightCompat, app:drawableBottomCompat, app:drawableStartCompat and app:drawableEndCompat

For regular drawable

If you don't need vector drawable, then you can

• use android:drawableLeft, android:drawableRight, android:drawableBottom, android:drawableTop
• You can use either regular TextView, Button & EditText or AppCompat classes.

You can achieve Output like below -

Yes you can do.

Syntax for CAST:

CAST ( expression AS data_type [ ( length ) ] )

For example:

CAST(MyColumn AS Varchar(10))

CAST in SELECT Statement:

Select CAST(MyColumn AS Varchar(10)) AS MyColumn
FROM MyTable

See for more information CAST and CONVERT (Transact-SQL)

Git will not store the password when you use URLs like that. Instead, it will just store the username, so it only needs to prompt you for the password the next time. As explained in the manual, to store the password, you should use an external credential helper. For Windows, you can use the Windows Credential Store for Git. This helper is also included by default in GitHub for Windows.

When using it, your password will automatically be remembered, so you only need to enter it once. So when you clone, you will be asked for your password, and then every further communication with the remote will not prompt you for your password again. Instead, the credential helper will provide Git with the authentication.

This of course only works for authentication via https; for ssh access ([email protected]/repository.git) you use SSH keys and those you can remember using ssh-agent (or PuTTY’s pageant if you’re using plink).

This one worked for me:

df=df.sort_values(by=[2])

Whereas:

df=df.sort_values(by=['2']) 

is not working.

On Linux (and probably most Unix), there is no OS-level DNS caching unless nscd is installed and running. Even then, the DNS caching feature of nscd is disabled by default at least in Debian because it's broken. The practical upshot is that your linux system very very probably does not do any OS-level DNS caching.

You could implement your own cache in your application (like they did for Squid, according to diegows's comment), but I would recommend against it. It's a lot of work, it's easy to get it wrong (nscd got it wrong!!!), it likely won't be as easily tunable as a dedicated DNS cache, and it duplicates functionality that already exists outside your application.

If an end user using your software needs to have DNS caching because the DNS query load is large enough to be a problem or the RTT to the external DNS server is long enough to be a problem, they can install a caching DNS server such as Unbound on the same machine as your application, configured to cache responses and forward misses to the regular DNS resolvers.

My problem ended up being permissions. I'm on a dev machine and copied via Homegroup. Somehow, probably based on where I copied the file to, the permissions got messed up and Management Studio couldn't read the file. Since this is dev I just gave Everyone permissions to the bak file and could then successfully restore via the GUI.

you can use this one.

<div id="test"></div>

you java script code should be like that.

setInterval(function(){
      $('#test').load('test.php');
 },5000);

1. Populate "Code Signing" in both "Project" and "Targets" section
2. Select valid entries in "Code Signing Identity" in both "Debug" and "Release"
3. Under "Debug" select you Developer certificate
4. Under "Release" select your Distributor certificate

Following these 4 steps always solves my issues.

You can't store "no character" in a character - it doesn't make sense.

As an alternative you could store a character that has a special meaning to you - e.g. null char '\0' - and treat this specially.

I'm surprised no one here has mentioned the html cell magic option. from the docs (IPython, but same for Jupyter)

%%html

Render the cell as a block of HTML

To produce the output in your comment to your post, this will do it:

use strict;
use warnings;

my @other_array = (0,0,0,1,2,2,3,3,3,4);
my @array;
my %uniqs;

$uniqs{$_}++ for @other_array;

foreach (keys %uniqs) { $array[$_]=$uniqs{$_} }

print "array[$_] = $array[$_]\n" for (0..$#array);

Output:

   array[0] = 3
   array[1] = 1
   array[2] = 2
   array[3] = 3
   array[4] = 1

This is different than your stated algorithm of producing a parallel array with zero values, but it is a more Perly way of doing it...

If you must have a parallel array that is the same size as your first array with the elements initialized to 0, this statement will dynamically do it: @array=(0) x scalar(@other_array); but really, you don't need to do that.

Form validation can be enabled in markup via the data-api or via JavaScript. Automatically enable form validation by adding data-toggle="validator" to your form element.

<form role="form" data-toggle="validator">
   ...
</form>

Or activate validation via JavaScript:

$('#myForm').validator()

and you need to use required flag in input field

Try:

var firstElement = lstComp.First();

You can also use FirstOrDefault() just in case lstComp does not contain any items.

http://msdn.microsoft.com/en-gb/library/bb340482(v=vs.100).aspx

Edit:

To get the Component Value:

var firstElement = lstComp.First().ComponentValue("Dep");

This would assume there is an element in lstComp. An alternative and safer way would be...

var firstOrDefault = lstComp.FirstOrDefault();
if (firstOrDefault != null) 
{
    var firstComponentValue = firstOrDefault.ComponentValue("Dep");
}

Use the following:

SELECT * FROM `calendar` WHERE DATE(startTime) = '2010-04-29'

Just for reference I have a 2 million record table, I ran a similar query. Salils answer took 4.48 seconds, the above took 2.25 seconds.

So if the table is BIG I would suggest this rather.

 sudo nano /etc/nginx/nginx.conf

Add these variables to nginx.conf file:

http {  
  # .....
  proxy_connect_timeout       600;
  proxy_send_timeout          600;
  proxy_read_timeout          600;
  send_timeout                600;
}

And then restart:

service nginx reload

Whenever you see this:

try:
    y = 1 / x
except ZeroDivisionError:
    pass
else:
    return y

Or even this:

try:
    return 1 / x
except ZeroDivisionError:
    return None

Consider this instead:

import contextlib
with contextlib.suppress(ZeroDivisionError):
    return 1 / x

Try this:

XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Path\To\Xml\File.xml");

Or alternatively if you have the XML in a string use the LoadXml method.

Once you have it loaded, you can use SelectNodes and SelectSingleNode to query specific values, for example:

XmlNode node = doc.SelectSingleNode("//Company/Email/text()");
// node.Value contains "[email protected]"

Finally, note that your XML is invalid as it doesn't contain a single root node. It must be something like this:

<Data>
    <Employee>
        <Name>Test</Name>
        <ID>123</ID>
    </Employee>
    <Company>
        <Name>ABC</Name>
        <Email>[email protected]</Email>
    </Company>
</Data>

I suggest you should use one of the mappers' libraries: Mapstruct, ModelMapper, etc. With Mapstruct your mapper will look like:

@Mapper
public interface UserMapper {     
    UserMapper INSTANCE = Mappers.getMapper( UserMapper.class ); 

    UserDTO toDto(User user);
}

The real object with all getters and setters will be automatically generated from this interface. You can use it like:

UserDTO userDTO = UserMapper.INSTANCE.toDto(user);

You can also add some logic for your activeText filed using @AfterMapping annotation.

I found this site helpful.

Prior to HTML5, input type="text" simply means a field to insert free text, regardless of what you want it be. that is the job of validations you would have to do in order to guarantee the user enters a valid number

If you're using HTML5, you can use the new input types, one of which is number that automatically validates the text input, and forces it to be a number

keep in mind though, that if you're building a server side app (php for example) you will still have to validate the input on that side (make sure it is really a number) since it's pretty easy to hack the html and change the input type, removing the browser validation

Surfing the web, you will find many technical justifications for Quadro price. Real answer is in "demand for reliable and task specific graphic cards".

Imagine you have an architectural firm with many fat projects on deadline. Your computers are only used in working with one specific CAD software. If foundation of your business is supposed to rely on these computers, you would want to make sure this foundation is strong.

For such clients, Nvidia engineered cards like Quadro, providing what they call "Professional Solution". And if you are among the targeted clients, you would really appreciate reliability of these graphic cards.

Many believe Geforce have become powerful and reliable enough to take Quadro's place. But in the end, it depends on the software you are mostly going to use and importance of reliability in what you do.

This will only work to column Z, but you can drag this horizontally and vertically.

=INDIRECT("'"&$D$2&"'!"&CHAR((COLUMN()+64))&ROW())

Ignore function is used to skip(discard/throw away) characters in the input stream. Ignore file is associated with the file istream. Consider the function below ex: cin.ignore(120,'/n'); the particular function skips the next 120 input character or to skip the characters until a newline character is read.

If you're using webservices, you'll also need the 'allow-http-request-headers-from' element. Here's our default, development, 'allow everything' policy.

<?xml version="1.0" ?>
<cross-domain-policy>
  <site-control permitted-cross-domain-policies="master-only"/>
  <allow-access-from domain="*"/>
  <allow-http-request-headers-from domain="*" headers="*"/>
</cross-domain-policy>

I think the easiest way to do is with backticks

mv `ls -1 ~/Linux/Old/ | grep -v Tux.png` ~/Linux/New/

Edit:

Use backslash with ls instead to prevent using it with alias, i.e. mostly ls is aliased as ls --color.

mv `\ls -1 ~/Linux/Old/ | grep -v Tux.png` ~/Linux/New/

Something to note here. We had the same issue with Windows VM's running on an ESXi host. The time sync was turned on in VMWare Tools on the guest, but the guest clocks were consistently off (by about 30 seconds) from the host clock. The ESXi host was configured to get time updates from an internal time server.

It turns out we had the Internet Time setting turned on in the Windows VM's (Control Panel > Date and Time > Internet Time tab) so the guest was getting time updates from two places and the internet time was winning. We turned that off and now the guest clocks are good, getting their time exclusively from the ESXi host.

Steps to set up Apache Bench(AB) on windows (IMO - Recommended).

Step 1 - Install Xampp.
Step 2 - Open CMD.
Step 3 - Go to the apache bench destination (cd C:\xampp\apache\bin) from CMD
Step 4 - Paste the command (ab -n 100 -c 10 -k -H "Accept-Encoding: gzip, deflate" http://localhost:yourport/)
Step 5 - Wait for it. Your done

Please change your code as follows:

<script>
    var button = document.getElementById("reactionTester");
    var start = document.getElementById("start");
    function init() {
        var startInterval/*in milliseconds*/ = Math.floor(Math.random()*30)*1000;
        setTimeout(startTimer,startInterval); 
    }
    function startTimer(){
        document.write("hey");
    }
</script>

See if that helps. Basically, the difference is references the 'startTimer' function instead of executing it.

Try Notepad++. It shows all characters. In addition, you could use the utility dos2unix to convert a file to all /n, or "conv" (same link) to convert either way.

As of today, the UI of developer tools in Google chrome has changed where we select the log level of log statements being shown in the console. There is a logging level drop down beside "Filter" text box. Supported values are Verbose, Info, Warnings and Errors with Info being the default selection.

Any log whose severity is equal or higher will get shown in the "Console" tab e.g. if selected log level is Info then all the logs having level Info, Warning and Error will get displayed in console.

When I changed it to Verbose then my console.debug and console.log statements started showing up in the console. Till the time Info level was selected they were not getting shown.

Although a bit hidden it's in the official docs here where can the library be found among the sdk's code, and how to get it with resources (the Eclipse way)

If none of the above is working, you are probably working on EDI trasaction where you need to validate your result against an HIPPA schema or any other complex xsd for that matter. The requirement is that, say there 8 REF segments and any of them have to appear in any order and also not all are required, means to say you may have them in following order 1st REF, 3rd REF , 2nd REF, 9th REF. Under default situation EDI receive will fail, beacause default complex type is

<xs:sequence>
  <xs:element.../>
</xs:sequence>

The situation is even complex when you are calling your element by refrence and then that element in its original spot is quite complex itself. for example:

<xs:element>
<xs:complexType>
<xs:sequence>
<element name="REF1"  ref= "REF1_Mycustomelment" minOccurs="0" maxOccurs="1">
<element name="REF2"  ref= "REF2_Mycustomelment" minOccurs="0" maxOccurs="1">
<element name="REF3"  ref= "REF3_Mycustomelment" minOccurs="0" maxOccurs="1">
</xs:sequence>
</xs:complexType>
</xs:element>

Solution:

Here simply replacing "sequence" with "all" or using "choice" with min/max combinations won't work!

First thing replace "xs:sequence" with "<xs:all>" Now,You need to make some changes where you are Referring the element from, There go to:

<xs:annotation>
  <xs:appinfo>
    <b:recordinfo structure="delimited" field.........Biztalk/2003">

***Now in the above segment add trigger point in the end like this trigger_field="REF01_...complete name.." trigger_value = "38" Do the same for other REF segments where trigger value will be different like say "18", "XX" , "YY" etc..so that your record info now looks like:b:recordinfo structure="delimited" field.........Biztalk/2003" trigger_field="REF01_...complete name.." trigger_value="38">

This will make each element unique, reason being All REF segements (above example) have same structure like REF01, REF02, REF03. And during validation the structure validation is ok but it doesn't let the values repeat because it tries to look for remaining values in first REF itself. Adding triggers will make them all unique and they will pass in any order and situational cases (like use 5 out 9 and not all 9/9).

Hope it helps you, for I spent almost 20 hrs on this.

Good Luck

These are usually to make sure that the browser gets a new version when the site gets updated with a new version, e.g. as part of our build process we'd have something like this:

/Resources/Combined.css?v=x.x.x.buildnumber

Since this changes with every new code push, the client's forced to grab a new version, just because of the querystring. Look at this page (at the time of this answer) for example:

<link ... href="http://sstatic.net/stackoverflow/all.css?v=c298c7f8233d">

I think instead of a revision number the SO team went with a file hash, which is an even better approach, even with a new release, the browsers only forced to grab a new version when the file actually changes.

Both of these approaches allow you to set the cache header to something ridiculously long, say 20 years...yet when it changes, you don't have to worry about that cache header, the browser sees a different querystring and treats it as a different, new file.

@Airspeed Velocity answer in Swift 2.0:

let str = "iOS Developer Tips encoded in Base64"
print("Original: \(str)")
let base64Encoded = str.dataUsingEncoding(NSUTF8StringEncoding)!.base64EncodedStringWithOptions([])
print("Encoded: \(base64Encoded)")
let base64DecodedData = NSData(base64EncodedString: base64Encoded, options: [])!
var base64DecodedString = String(data: base64DecodedData, encoding: NSUTF8StringEncoding)!
print("Decoded: \(base64DecodedString)")

SQLite does not have a storage class set aside for storing dates and/or times. Instead, the built-in Date And Time Functions of SQLite are capable of storing dates and times as TEXT, REAL, or INTEGER values:

TEXT as ISO8601 strings ("YYYY-MM-DD HH:MM:SS.SSS"). REAL as Julian day numbers, the number of days since noon in Greenwich on November 24, 4714 B.C. according to the proleptic Gregorian calendar. INTEGER as Unix Time, the number of seconds since 1970-01-01 00:00:00 UTC. Applications can chose to store dates and times in any of these formats and freely convert between formats using the built-in date and time functions.

Having said that, I would use INTEGER and store seconds since Unix epoch (1970-01-01 00:00:00 UTC).

Here, i'm creating instance of my class

No, you are not creating the instance of your abstract class here. Rather you are creating an instance of an anonymous subclass of your abstract class. And then you are invoking the method on your abstract class reference pointing to subclass object.

This behaviour is clearly listed in JLS - Section # 15.9.1: -

If the class instance creation expression ends in a class body, then the class being instantiated is an anonymous class. Then:

• If T denotes a class, then an anonymous direct subclass of the class named by T is declared. It is a compile-time error if the class denoted by T is a final class.
• If T denotes an interface, then an anonymous direct subclass of Object that implements the interface named by T is declared.
• In either case, the body of the subclass is the ClassBody given in the class instance creation expression.
• The class being instantiated is the anonymous subclass.

Emphasis mine.

Also, in JLS - Section # 12.5, you can read about the Object Creation Process. I'll quote one statement from that here: -

Whenever a new class instance is created, memory space is allocated for it with room for all the instance variables declared in the class type and all the instance variables declared in each superclass of the class type, including all the instance variables that may be hidden.

Just before a reference to the newly created object is returned as the result, the indicated constructor is processed to initialize the new object using the following procedure:

You can read about the complete procedure on the link I provided.

To practically see that the class being instantiated is an Anonymous SubClass, you just need to compile both your classes. Suppose you put those classes in two different files:

My.java:

abstract class My {
    public void myMethod() {
        System.out.print("Abstract");
    }
}

Poly.java:

class Poly extends My {
    public static void main(String a[]) {
        My m = new My() {};
        m.myMethod();
    }
}

Now, compile both your source files:

javac My.java Poly.java

Now in the directory where you compiled the source code, you will see the following class files:

My.class
Poly$1.class  // Class file corresponding to anonymous subclass
Poly.class

See that class - Poly$1.class. It's the class file created by the compiler corresponding to the anonymous subclass you instantiated using the below code:

new My() {};

So, it's clear that there is a different class being instantiated. It's just that, that class is given a name only after compilation by the compiler.

In general, all the anonymous subclasses in your class will be named in this fashion:

Poly$1.class, Poly$2.class, Poly$3.class, ... so on

Those numbers denote the order in which those anonymous classes appear in the enclosing class.

A Stacked bar chart should suffice:

Setup data as follows

Name    Start       End         Duration (End - Start)
Fred    1/01/1981   1/06/1985    1612   
Bill    1/07/1985   1/11/2000    5602  
Joe     1/01/1980   1/12/2001    8005  
Jim     1/03/1999   1/01/2000    306  

1. Plot Start and Duration as a stacked bar chart
2. Set the X-Axis minimum to the desired start date
3. Set the Fill Colour of thestart range to no fill
4. Set the Fill of individual bars to suit

(example prepared in Excel 2010)

From now you can also :

Action<int> action = (o) => Thread.Sleep(o);
int param = 10;
await new TaskFactory().StartNew(action, param)

If you are using a relatively recent version of JSHint, the generally preferred approach is to create a .jshintrc file in the root of your project, and put this config in it:

{
    "globals": {
        "$": false
    }
}

This declares to JSHint that $ is a global variable, and the false indicates that it should not be overridden.

The .jshintrc file was not supported in really old versions of JSHint (such as v0.5.5 like the original question in 2012). If you cannot or do not want to use the .jshintrc file, you can add this at the top of the script file:

/*globals $:false */

There is also a shorthand "jquery" jshint option as seen on the JSHint options page..

There are different types of users behind the Internet, so we want to catch the IP address from different portions. Those are:

1. $_SERVER['REMOTE_ADDR'] - This contains the real IP address of the client. That is the most reliable value you can find from the user.

2. $_SERVER['REMOTE_HOST'] - This will fetch the host name from which the user is viewing the current page. But for this script to work, hostname lookups on inside httpd.conf must be configured.

3. $_SERVER['HTTP_CLIENT_IP'] - This will fetch the IP address when the user is from shared Internet services.

4. $_SERVER['HTTP_X_FORWARDED_FOR'] - This will fetch the IP address from the user when he/she is behind the proxy.

So we can use this following combined function to get the real IP address from users who are viewing in diffrent positions,

// Function to get the user IP address
function getUserIP() {
    $ipaddress = '';
    if (isset($_SERVER['HTTP_CLIENT_IP']))
        $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
    else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
        $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
    else if(isset($_SERVER['HTTP_X_FORWARDED']))
        $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
    else if(isset($_SERVER['HTTP_X_CLUSTER_CLIENT_IP']))
        $ipaddress = $_SERVER['HTTP_X_CLUSTER_CLIENT_IP'];
    else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
        $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
    else if(isset($_SERVER['HTTP_FORWARDED']))
        $ipaddress = $_SERVER['HTTP_FORWARDED'];
    else if(isset($_SERVER['REMOTE_ADDR']))
        $ipaddress = $_SERVER['REMOTE_ADDR'];
    else
        $ipaddress = 'UNKNOWN';
    return $ipaddress;
}

There is no right way, but you can initialize an array of literals:

char **values = (char *[]){"a", "b", "c"};

or you can allocate each and initialize it:

char **values = malloc(sizeof(char*) * s);
for(...)
{
    values[i] = malloc(sizeof(char) * l);
    //or
    values[i] = "hello";
}

If you are targeting iOS7 and already have the image split into frames you can use animatedImageNamed:duration:.

Let's say you are animating a spinner. Copy all of your frames into the project and name them as follows:

• spinner-1.png
• spinner-2.png
• spinner-3.png
• etc.,

Then create the image via:

[UIImage animatedImageNamed:@"spinner-" duration:1.0f];

From the docs:

This method loads a series of files by appending a series of numbers to the base file name provided in the name parameter. For example, if the name parameter had ‘image’ as its contents, this method would attempt to load images from files with the names ‘image0’, ‘image1’ and so on all the way up to ‘image1024’. All images included in the animated image should share the same size and scale.

patterns module is not supported.. mine worked with this.

from django.conf.urls import *
from django.contrib import admin
admin.autodiscover()

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    # ... your url patterns
]

An alternative to what was proposed before is:

jQuery('form').submit(function(){
     $(this).find(':submit').attr( 'disabled','disabled' );
     //the rest of your code
});

If you're looking to print specific data that you already have access to, whether it's from a Store, AJAX, or available elsewhere, you can leverage my library react-print.

https://github.com/captray/react-print

It makes creating print templates much easier (assuming you already have a dependency on react). You just need to tag your HTML appropriately.

This ID should be added higher up in your actual DOM tree to exclude everything except the "print mount" below.

<div id="react-no-print"> 

This is where your react-print component will mount and wrap your template that you create:

<div id="print-mount"></div>

An example looks something like this:

var PrintTemplate = require('react-print');
var ReactDOM = require('react-dom');
var React = require('react');

var MyTemplate = React.createClass({
    render() {
        return (
            <PrintTemplate>
                <p>Your custom</p>
                <span>print stuff goes</span>
                <h1>Here</h1>
            </PrintTemplate>
        );
    }
});

ReactDOM.render(<MyTemplate/>, document.getElementById('print-mount'));

It's worth noting that you can create new or utilize existing child components inside of your template, and everything should render fine for printing.

I meet the same problem, @progrAmmar enlightened me, "took a closer look at the user table in mysql database".

My problem is not ssl_type, instead of the first field:Host. I changed the value by using

update user set Host='localhost' where User='root' and Host='%';

in mysqld_safe --skip-grant-tables model.

Then it works well.

Use Manatee.Json https://github.com/gregsdennis/Manatee.Json/wiki/Usage

And you can convert the entire object to a string, filename.json is expected to be located in documents folder.

        var text = File.ReadAllText("filename.json");
        var json = JsonValue.Parse(text);

        while (JsonValue.Null != null)
        {
            Console.WriteLine(json.ToString());

        }
        Console.ReadLine();

Systemd which now runs in the majority of distros

Step 1:

Find your user defined services mine was at /usr/lib/systemd/system/

Step 2:

Create a text file with your favorite text editor name it whatever_you_want.service

Step 3:

Put following Template to the file whatever_you_want.service

[Unit]
Description=webserver Daemon

[Service]
ExecStart=/usr/bin/java -jar /web/server.jar
User=user

[Install]
WantedBy=multi-user.target

Step 4:

Run your service
as super user

$ systemctl start whatever_you_want.service # starts the service
$ systemctl enable whatever_you_want.service # auto starts the service
$ systemctl disable whatever_you_want.service # stops autostart
$ systemctl stop whatever_you_want.service # stops the service
$ systemctl restart whatever_you_want.service # restarts the service

I just had the same problem: You have to unserialize the data on the php side.

Add to the beginning of your php file (Attention this short version would replace all other post variables):

parse_str($_POST["data"], $_POST);

For me above solutions didn't work then I tried

map.setCenter(new google.maps.LatLng(lat, lng));

and it worked as expected.

Use for on refresh event

window.onbeforeunload = function(e) {
  return 'Dialog text here.';
};

https://developer.mozilla.org/en-US/docs/Web/API/window.onbeforeunload?redirectlocale=en-US&redirectslug=DOM%2Fwindow.onbeforeunload

And

$(window).unload(function() {
      alert('Handler for .unload() called.');
});

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

I solved it in my site making this in functions.php

add_action("template_redirect", "start_buffer");
add_action("shutdown", "end_buffer", 999);

function filter_buffer($buffer) {
    $buffer = replace_insecure_links($buffer);
    return $buffer;
}
function start_buffer(){
    ob_start("filter_buffer");
}

function end_buffer(){
    if (ob_get_length()) ob_end_flush();
}

function replace_insecure_links($str) {

   $str = str_replace ( array("http://www.yoursite.com/", "https://www.yoursite.com/") , array("/", "/"), $str);

   return apply_filters("rsssl_fixer_output", $str);

}

I took part of one plugin, cut it into pieces and make this. It replaced ALL links in my site (menus, css, scripts etc.) and everything was working.

In my case

OS Version: Ubuntu 18.04.4 LTS

Node version v12.16.0

Remove ng from /usr/local/bin by using below command.

sudo rm -r ng

After that, installed ng by using command mentioned below.

sudo npm install -g @angular/cli

It took a while to put together a solution for this, but have found this is the easiest way to get it to work in the way that you describe. There could be better ways to do this, but since you haven't posted your activity code I will have to improvise and assume you have a list like this at the start of your activity:

private List<String> items = db.getItems();

ExampleActivity.java

private List<String> items;

private Menu menu;

@Override
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public boolean onCreateOptionsMenu(Menu menu) {

    getMenuInflater().inflate(R.menu.example, menu);

    this.menu = menu;

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {

        SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);

        SearchView search = (SearchView) menu.findItem(R.id.search).getActionView();

        search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));

        search.setOnQueryTextListener(new OnQueryTextListener() { 

            @Override 
            public boolean onQueryTextChange(String query) {

                loadHistory(query);

                return true; 

            } 

        });

    }

    return true;

}

// History
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
private void loadHistory(String query) {

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {

        // Cursor
        String[] columns = new String[] { "_id", "text" };
        Object[] temp = new Object[] { 0, "default" };

        MatrixCursor cursor = new MatrixCursor(columns);

        for(int i = 0; i < items.size(); i++) {

            temp[0] = i;
            temp[1] = items.get(i);

            cursor.addRow(temp);

        }

        // SearchView
        SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);

        final SearchView search = (SearchView) menu.findItem(R.id.search).getActionView();

        search.setSuggestionsAdapter(new ExampleAdapter(this, cursor, items));

    }

}

Now you need to create an adapter extended from CursorAdapter:

ExampleAdapter.java

public class ExampleAdapter extends CursorAdapter {

    private List<String> items;

    private TextView text;

    public ExampleAdapter(Context context, Cursor cursor, List<String> items) {

        super(context, cursor, false);

        this.items = items;

    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {

        text.setText(items.get(cursor.getPosition()));

    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {

        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View view = inflater.inflate(R.layout.item, parent, false);

        text = (TextView) view.findViewById(R.id.text);

        return view;

    }

}

A better way to do this is if your list data is from a database, you can pass the Cursor returned by database functions directly to ExampleAdapter and use the relevant column selector to display the column text in the TextView referenced in the adapter.

Please note: when you import CursorAdapter don't import the Android support version, import the standard android.widget.CursorAdapter instead.

The adapter will also require a custom layout:

res/layout/item.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <TextView
        android:id="@+id/item"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</RelativeLayout>

You can now customize list items by adding additional text or image views to the layout and populating them with data in the adapter.

This should be all, but if you haven't done this already you need a SearchView menu item:

res/menu/example.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@+id/search"
        android:title="@string/search"
        android:showAsAction="ifRoom"
        android:actionViewClass="android.widget.SearchView" />

</menu>

Then create a searchable configuration:

res/xml/searchable.xml

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/search"
    android:hint="@string/search" >
</searchable>

Finally add this inside the relevant activity tag in the manifest file:

AndroidManifest.xml

<intent-filter>
    <action android:name="android.intent.action.SEARCH" />
</intent-filter>

<meta-data
    android:name="android.app.default_searchable"
    android:value="com.example.ExampleActivity" />
<meta-data
    android:name="android.app.searchable"
    android:resource="@xml/searchable" />

Please note: The @string/search string used in the examples should be defined in values/strings.xml, also don't forget to update the reference to com.example for your project.

Below are two methods that are superior to looping. Both handle a "no-find" case.

1. The VBA equivalent of a normal function VLOOKUP with error-handling if the variable doesn't exist (INDEX/MATCH may be a better route than VLOOKUP, ie if your two columns A and B were in reverse order, or were far apart)

2. VBAs FIND method (matching a whole string in column A given I use the xlWhole argument)

   Sub Method1()
   Dim strSearch As String
   Dim strOut As String
   Dim bFailed As Boolean
   
   strSearch = "trees"
   
   On Error Resume Next
   strOut = Application.WorksheetFunction.VLookup(strSearch, Range("A:B"), 2, False)
   If Err.Number <> 0 Then bFailed = True
   On Error GoTo 0
   
   If Not bFailed Then
   MsgBox "corresponding value is " & vbNewLine & strOut
   Else
   MsgBox strSearch & " not found"
   End If
   End Sub
   
   Sub Method2()
       Dim rng1 As Range
       Dim strSearch As String
       strSearch = "trees"
       Set rng1 = Range("A:A").Find(strSearch, , xlValues, xlWhole)
       If Not rng1 Is Nothing Then
           MsgBox "Find has matched " & strSearch & vbNewLine & "corresponding cell is " & rng1.Offset(0, 1)
       Else
           MsgBox strSearch & " not found"

I was facing the same problem, I googled and tried suggestions I found but none of them worked for me. I changed my workspace and it worked, but before changing your workspace try other workarounds you have. Any one of them might work for you.

As of Pandas version 0.22, there exists also an alternative to apply: pipe, which can be considerably faster than using apply (you can also check this question for more differences between the two functionalities).

For your example:

df = pd.DataFrame({"my_label": ['A','B','A','C','D','D','E']})

  my_label
0        A
1        B
2        A
3        C
4        D
5        D
6        E

The apply version

df.groupby('my_label').apply(lambda grp: grp.count() / df.shape[0])

gives

          my_label
my_label          
A         0.285714
B         0.142857
C         0.142857
D         0.285714
E         0.142857

and the pipe version

df.groupby('my_label').pipe(lambda grp: grp.size() / grp.size().sum())

yields

my_label
A    0.285714
B    0.142857
C    0.142857
D    0.285714
E    0.142857

So the values are identical, however, the timings differ quite a lot (at least for this small dataframe):

%timeit df.groupby('my_label').apply(lambda grp: grp.count() / df.shape[0])
100 loops, best of 3: 5.52 ms per loop

and

%timeit df.groupby('my_label').pipe(lambda grp: grp.size() / grp.size().sum())
1000 loops, best of 3: 843 µs per loop

Wrapping it into a function is then also straightforward:

def get_perc(grp_obj):
    gr_size = grp_obj.size()
    return gr_size / gr_size.sum()

Now you can call

df.groupby('my_label').pipe(get_perc)

yielding

my_label
A    0.285714
B    0.142857
C    0.142857
D    0.285714
E    0.142857

However, for this particular case, you do not even need a groupby, but you can just use value_counts like this:

df['my_label'].value_counts(sort=False) / df.shape[0]

yielding

A    0.285714
C    0.142857
B    0.142857
E    0.142857
D    0.285714
Name: my_label, dtype: float64

For this small dataframe it is quite fast

%timeit df['my_label'].value_counts(sort=False) / df.shape[0]
1000 loops, best of 3: 770 µs per loop

As pointed out by @anmol, the last statement can also be simplified to

df['my_label'].value_counts(sort=False, normalize=True)

As others have mentioned, there can be multiple reasons for this error.

If you are using SSH with Smart Card (PIV), and adding the card to ssh-agent with
ssh-add -s /usr/lib64/pkcs11/opensc-pkcs11.so
you may get the error
sign_and_send_pubkey: signing failed: agent refused operation
from ssh if the PIV authentication has expired, or if you have removed and reinserted the PIV card.

In that case, if you try to do another ssh-add -s you will still get an error:
Could not add card "/usr/lib64/opensc-pkcs11.so": agent refused operation

According to RedHat Bug 1609055 - pkcs11 support in agent is clunky, you instead need to do

ssh-add -e /usr/lib64/opensc-pkcs11.so
ssh-add -s /usr/lib64/opensc-pkcs11.so

MAKE this

In XAMPP, intl extension is included but you have to uncomment extension=php_intl.dll in php.ini and restart the server through the XAMPP Control Panel. In WAMP, the intl extension is “activated” by default but not working. To make it work you have to go to php folder (by default) C:\wamp\bin\php\php{version}, copy all the files that looks like icu*.dll and paste them into the apache bin directory C:\wamp\bin\apache\apache{version}\bin. Then restart all services and it should be OK.

if you use XAMPP do this 1. turn off XAMPP 2. Modifed the php.ini is located in c/:xampp/php/php.ini 3. intl extension is included but you have to uncomment extension=php_intl.dll in php.ini and restart the server through the XAMPP Control Panel.

If I use exit() in a code and run it in the shell, it shows a message asking whether I want to kill the program or not. It's really disturbing. See here

But sys.exit() is better in this case. It closes the program and doesn't create any dialogue box.

In the past I've used the style found here

<Style x:Key="VerticalSeparatorStyle" 
       TargetType="{x:Type Separator}"
       BasedOn="{StaticResource {x:Type Separator}}">
    <Setter Property="Margin" Value="6,0,6,0"/>
    <Setter Property="LayoutTransform">
        <Setter.Value>
            <TransformGroup>
                <TransformGroup.Children>
                    <TransformCollection>
                        <RotateTransform Angle="90"/>
                    </TransformCollection>
                </TransformGroup.Children>
            </TransformGroup>
        </Setter.Value>
    </Setter>
</Style>

<Separator Style="{DynamicResource VerticalSeparatorStyle}" />

You need to set the transformation in LayoutTransform instead of RenderTransform so the transformation occurs during the Layout pass, not during the Render pass. The Layout pass occurs when WPF is trying to layout controls and figure out how much space each control takes up, while the Render pass occurs after the layout pass when WPF is trying to render controls.

You can read more about the difference between LayoutTransform and RenderTransform here or here

Those are some very nice, but lengthy answers.

To sum up my experiences:

1. Controllers and providers (services, factories, etc.) are for modifying the data model, NOT HTML.
2. HTML and directives define the layout and binding to the model.
3. If you need to share data between controllers, create a service or factory - they are singletons that are shared across the application.
4. If you need an HTML widget, create a directive.
5. If you have some data and are now trying to update HTML... STOP! update the model, and make sure your HTML is bound to the model.

On a high level, if you observe as to where normalization/standardization is mostly used, you will notice that, anytime there is a use of magnitude difference in model building process, it becomes necessary to standardize the inputs so as to ensure that important inputs with small magnitude don't loose their significance midway the model building process.

example:

v(3-1)^2+(1000-900)^2 ˜ v(1000-900)^2

Here, (3-1) contributes hardly a thing to the result and hence the input corresponding to these values is considered futile by the model.

Consider the following:

1. Clustering uses euclidean or, other distance measures.
2. NNs use optimization algorithm to minimise cost function(ex. - MSE).

Both distance measure(Clustering) and cost function(NNs) use magnitude difference in some way and hence standardization ensures that magnitude difference doesn't command over important input parameters and the algorithm works as expected.

try this

$("#inp").focus(function(){$("#sel").attr('disabled','true');});

$("#inp").blur(function(){$("#sel").removeAttr('disabled');});

vice versa for the select also.

You can also reference the obj once you are inside the function instead of this.

var obj = {
    key1: "it",
    key2: function(){return obj.key1 + " works!"}
};
alert(obj.key2());

Most RDBMS products will optimize both queries identically. In "SQL Performance Tuning" by Peter Gulutzan and Trudy Pelzer, they tested multiple brands of RDBMS and found no performance difference.

I prefer to keep join conditions separate from query restriction conditions.

If you're using OUTER JOIN sometimes it's necessary to put conditions in the join clause.

Right answer

To do so, just npm version patch =)

My old answer

There is no pre-release hook originally in git. At least, man githooks does not show it.

If you're using git-extra (https://github.com/visionmedia/git-extras), for instance, you can use a pre-release hook which is implemented by it, as you can see at https://github.com/visionmedia/git-extras/blob/master/bin/git-release. It is needed only a .git/hook/pre-release.sh executable file which edits your package.json file. Committing, pushing and tagging will be done by the git release command.

If you're not using any extension for git, you can write a shell script (I'll name it git-release.sh) and than you can alias it to git release with something like:

git config --global alias.release '!sh path/to/pre-release.sh $1'

You can, than, use git release 0.4 which will execute path/to/pre-release.sh 0.4. Your script can edit package.json, create the tag and push it to the server.

Use the link to Visual C++ 2015 Build Tools. That will install Visual C++ 14.0 without installing Visual Studio.

Try CountA:

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

You can convert BigDecimal to double using .doubleValue(). But believe me, don't use it if you have currency manipulations. It should always be performed on BigDecimal objects directly. Precision loss in these calculations are big time problems in currency related calculations.

You can accomplish this (if I understand what you are trying to do) using dynamic SQL.

The trick is that you need to create a string containing the SQL statement. That's because the tablename has to specified in the actual SQL text, when you execute the statement. The table references and column references can't be supplied as parameters, those have to appear in the SQL text.

So you can use something like this approach:

SET @stmt = 'INSERT INTO @tmpTbl1 SELECT ' + @KeyValue 
    + ' AS fld1 FROM tbl' + @KeyValue

EXEC (@stmt)

First, we create a SQL statement as a string. Given a @KeyValue of 'Foo', that would create a string containing:

'INSERT INTO @tmpTbl1 SELECT Foo AS fld1 FROM tblFoo'

At this point, it's just a string. But we can execute the contents of the string, as a dynamic SQL statement, using EXECUTE (or EXEC for short).

The old-school sp_executesql procedure is an alternative to EXEC, another way to execute dymamic SQL, which also allows you to pass parameters, rather than specifying all values as literals in the text of the statement.

FOLLOWUP

EBarr points out (correctly and importantly) that this approach is susceptible to SQL Injection.

Consider what would happen if @KeyValue contained the string:

'1 AS foo; DROP TABLE students; -- '

The string we would produce as a SQL statement would be:

'INSERT INTO @tmpTbl1 SELECT 1 AS foo; DROP TABLE students; -- AS fld1 ...'

When we EXECUTE that string as a SQL statement:

INSERT INTO @tmpTbl1 SELECT 1 AS foo;
DROP TABLE students;
-- AS fld1 FROM tbl1 AS foo; DROP ...

And it's not just a DROP TABLE that could be injected. Any SQL could be injected, and it might be much more subtle and even more nefarious. (The first attacks can be attempts to retreive information about tables and columns, followed by attempts to retrieve data (email addresses, account numbers, etc.)

One way to address this vulnerability is to validate the contents of @KeyValue, say it should contain only alphabetic and numeric characters (e.g. check for any characters not in those ranges using LIKE '%[^A-Za-z0-9]%'. If an illegal character is found, then reject the value, and exit without executing any SQL.

limit option, e.g.:

svn log --limit 4

svn log -l 4

Only the last 4 entries

Or simply:

System.out.println("Some text");

Have you tried jQuery.contents() ?

You cannot add a column with a default value in Hive. You have the right syntax for adding the column ALTER TABLE test1 ADD COLUMNS (access_count1 int);, you just need to get rid of default sum(max_count). No changes to that files backing your table will happen as a result of adding the column. Hive handles the "missing" data by interpreting NULL as the value for every cell in that column.

So now your have the problem of needing to populate the column. Unfortunately in Hive you essentially need to rewrite the whole table, this time with the column populated. It may be easier to rerun your original query with the new column. Or you could add the column to the table you have now, then select all of its columns plus value for the new column.

You also have the option to always COALESCE the column to your desired default and leave it NULL for now. This option fails when you want NULL to have a meaning distinct from your desired default. It also requires you to depend on always remembering to COALESCE.

If you are very confident in your abilities to deal with the files backing Hive, you could also directly alter them to add your default. In general I would recommend against this because most of the time it will be slower and more dangerous. There might be some case where it makes sense though, so I've included this option for completeness.

Yes, it can be done.
It is based on the new html5 "download" attribute of anchor tags.
The flow should be something like this :

1. load the image
2. draw the image into a canvas with the crop boundaries specified
3. get the image data from the canvas and make it a href attribute for an anchor tag in the dom
4. add the download attribute (download="desired-file-name") to that a element That's it. all the user has to do is click your "download link" and the image will be downloaded to his pc.

I'll come back with a demo when I get the chance.

Update
Here's the live demo as I promised. It takes the jsfiddle logo and crops 5px of each margin.
The code looks like this :

var img = new Image();
img.onload = function(){
    var cropMarginWidth = 5,
        canvas = $('<canvas/>')
                    .attr({
                         width: img.width - 2 * cropMarginWidth,
                         height: img.height - 2 * cropMarginWidth
                     })
                    .hide()
                    .appendTo('body'),
        ctx = canvas.get(0).getContext('2d'),
        a = $('<a download="cropped-image" title="click to download the image" />'),
        cropCoords = {
            topLeft : {
                x : cropMarginWidth,
                y : cropMarginWidth 
            },
            bottomRight :{
                x : img.width - cropMarginWidth,
                y : img.height - cropMarginWidth
            }
        };

    ctx.drawImage(img, cropCoords.topLeft.x, cropCoords.topLeft.y, cropCoords.bottomRight.x, cropCoords.bottomRight.y, 0, 0, img.width, img.height);
    var base64ImageData = canvas.get(0).toDataURL();


    a
        .attr('href', base64ImageData)
        .text('cropped image')
        .appendTo('body');

    a
        .clone()
        .attr('href', img.src)
        .text('original image')
        .attr('download','original-image')
        .appendTo('body');

    canvas.remove();
}
img.src = 'some-image-src';

Update II
Forgot to mention : of course there is a downside :(.
Because of the same-origin policy that is applied to images too, if you want to access an image's data (through the canvas method toDataUrl).
So you would still need a server-side proxy that would serve your image as if it were hosted on your domain.

Update III Although I can't provide a live demo for this (for security reasons), here is a php sample code that solves the same-origin policy :

file proxy.php :

$imgData = getimagesize($_GET['img']);
header("Content-type: " . $imgData['mime']);
echo file_get_contents($_GET['img']);  

This way, instead of loading the external image direct from it's origin :

img.src = 'http://some-domain.com/imagefile.png';

You can load it through your proxy :

img.src = 'proxy.php?img=' + encodeURIComponent('http://some-domain.com/imagefile.png');  

And here's a sample php code for saving the image data (base64) into an actual image :

file save-image.php :

$data = preg_replace('/data:image\/(png|jpg|jpeg|gif|bmp);base64/','',$_POST['data']);
$data = base64_decode($data);
$img = imagecreatefromstring($data);

$path = 'path-to-saved-images/';
// generate random name
$name  = substr(md5(time()),10);
$ext = 'png';
$imageName = $path.$name.'.'.$ext;

// write the image to disk
imagepng($img,  $imageName);
imagedestroy($img);
// return the image path
echo $imageName;

All you have to do then is post the image data to this file and it will save the image to disc and return you the existing image filename.

Of course all this might feel a bit complicated, but I wanted to show you that what you're trying to achieve is possible.

It's called the carriage return, or \r

Use

print i/len(some_list)*100," percent complete         \r",

The comma prevents print from adding a newline. (and the spaces will keep the line clear from prior output)

Also, don't forget to terminate with a print "" to get at least a finalizing newline!
