See http://wiki.apache.org/httpd/DistrosDefaultLayout for discussion of where you might find Apache httpd configuration files on various platforms, since this can vary from release to release and platform to platform. The most common answer, however, is either /etc/apache/conf or /etc/httpd/conf

Generically, you can determine the answer by running the command:

httpd -V

(That's a capital V). Or, on systems where httpd is renamed, perhaps apache2ctl -V

This will return various details about how httpd is built and configured, including the default location of the main configuration file.

One of the lines of output should look like:

-D SERVER_CONFIG_FILE="conf/httpd.conf"

which, combined with the line:

-D HTTPD_ROOT="/etc/httpd"

will give you a full path to the default location of the configuration file

I got this exception while coping a object(variable) Matrix Array into Excel sheet. The solution to this is, Matrix array Index(i,j) must start from (0,0) whereas Excel sheet should start with Matrix Array index (i,j) from (1,1) .

I hope you this concept.

In general you can say session.gc_maxlifetime specifies the maximum lifetime since the last change of your session data (not the last time session_start was called!). But PHP’s session handling is a little bit more complicated.

Because the session data is removed by a garbage collector that is only called by session_start with a probability of session.gc_probability devided by session.gc_divisor. The default values are 1 and 100, so the garbage collector is only started in only 1% of all session_start calls. That means even if the the session is already timed out in theory (the session data had been changed more than session.gc_maxlifetime seconds ago), the session data can be used longer than that.

Because of that fact I recommend you to implement your own session timeout mechanism. See my answer to How do I expire a PHP session after 30 minutes? for more details.

NSMutableArray *persons = [NSMutableArray array];
for (int i = 0; i < myPersonsCount; i++) {
   [persons addObject:[[Person alloc] init]];
}
NSArray *arrayOfPersons = [NSArray arrayWithArray:persons]; // if you want immutable array

also you can reach this without using NSMutableArray:

NSArray *persons = [NSArray array];
for (int i = 0; i < myPersonsCount; i++) {
   persons = [persons arrayByAddingObject:[[Person alloc] init]];
}

One more thing - it's valid for ARC enabled environment, if you going to use it without ARC don't forget to add autoreleased objects into array!

[persons addObject:[[[Person alloc] init] autorelease];

Script oldfiles

I've tried to answer this question in a more complete way, and I ended up creating a complete script with options to help you understand the find command.

The script oldfiles is in this repository

To "create" a new find command you run it with the option -n (dry-run), and it will print to you the correct find command you need to use.

Of course, if you omit the -n it will just run, no need to retype the find command.

Usage:

$ oldfiles [-v...] ([-h|-V|-n] | {[(-a|-u) | (-m|-t) | -c] (-i | -d | -o| -y | -g) N (-\> | -\< | -\=) [-p "pat"]})

• Where the options are classified in the following groups:
  • Help & Info:

    -h, --help : Show this help.
    -V, --version : Show version.
    -v, --verbose : Turn verbose mode on (cumulative).
    -n, --dry-run : Do not run, just explain how to create a "find" command

  • Time type (access/use, modification time or changed status):

    -a or -u : access (use) time
    -m or -t : modification time (default)
    -c : inode status change

  • Time range (where N is a positive integer):

    -i N : minutes (default, with N equal 1 min)
    -d N : days
    -o N : months
    -y N : years
    -g N : N is a DATE (example: "2017-07-06 22:17:15")

  • Tests:

    -p "pat" : optional pattern to match (example: -p "*.c" to find c files) (default -p "*")
    -\> : file is newer than given range, ie, time modified after it.
    -\< : file is older than given range, ie, time is from before it. (default)
    -\= : file that is exactly N (min, day, month, year) old.

Example:

• Find C source files newer than 10 minutes (access time) (with verbosity 3):

$ oldfiles -a -i 10 -p"*.c" -\> -nvvv Starting oldfiles script, by beco, version 20170706.202054... $ oldfiles -vvv -a -i 10 -p "*.c" -\> -n Looking for "*.c" files with (a)ccess time newer than 10 minute(s) find . -name "*.c" -type f -amin -10 -exec ls -ltu --time-style=long-iso {} + Dry-run

• Find H header files older than a month (modification time) (verbosity 2):

$ oldfiles -m -o 1 -p"*.h" -\< -nvv Starting oldfiles script, by beco, version 20170706.202054... $ oldfiles -vv -m -o 1 -p "*.h" -\< -n find . -name "*.h" -type f -mtime +30 -exec ls -lt --time-style=long-iso {} + Dry-run

• Find all (*) files within a single day (Dec, 1, 2016; no verbosity, dry-run):

$ oldfiles -mng "2016-12-01" -\= find . -name "*" -type f -newermt "2016-11-30 23:59:59" ! -newermt "2016-12-01 23:59:59" -exec ls -lt --time-style=long-iso {} +

Of course, removing the -n the program will run the find command itself and save you the trouble.

I hope this helps everyone finally learn this {a,c,t}{time,min} options.

the LS output:

You will also notice that the "ls" option ls OPT changes to match the type of time you choose.

Here is the code I use when I want to preload images before appending them to the page.

It is also important to check if the image is already loaded from the cache (for IE).

    //create image to preload:
    var imgPreload = new Image();
    $(imgPreload).attr({
        src: photoUrl
    });

    //check if the image is already loaded (cached):
    if (imgPreload.complete || imgPreload.readyState === 4) {

        //image loaded:
        //your code here to insert image into page

    } else {
        //go fetch the image:
        $(imgPreload).load(function (response, status, xhr) {
            if (status == 'error') {

                //image could not be loaded:

            } else {

                //image loaded:
                //your code here to insert image into page

            }
        });
    }

On Mac OS X Catalina it appears to follow the Linux path. Using any of:

pip install pipenv
pip3 install pipenv
sudo pip install pipenv
sudo pip3 install pipenv

Essentially installs pipenv here:

/Users/mike/Library/Python/3.7/lib/python/site-packages/pipenv

But its not the executable and so is never found. The only thing that worked for me was

pip install --user pipenv

This seems to result in an __init__.py file in the above directory that has contents to correctly expose the pipenv command.

and everything started working, when all other posted and commented suggestions on this question failed.

The pipenv package certainly seems quite picky.

In modern browsers, you can accomplish this with string.matchAll().

The benefit to this approach vs RegExp.exec() is that it does not rely on the regex being stateful, as in @Gumbo's answer.

let regexp = /bar/g;
let str = 'foobarfoobar';

let matches = [...str.matchAll(regexp)];
matches.forEach((match) => {
    console.log("match found at " + match.index);
});

Also, I want to mention one more thing.

When you start an application from adb shell am, it automatically adds FLAG_ACTIVITY_NEW_TASK flag which makes behavior change. See the code.

For example, if you launch Play Store activity from adb shell am, pressing 'Back' button(hardware back button) wouldn't take you your app, instead it would take you previous Play Store activity if there was some(If there was not Play store task, then it would take you your app). FLAG_ACTIVITY_NEW_TASK documentation says :

if a task is already running for the activity you are now starting, then a new activity will not be started; instead, the current task will simply be brought to the front of the screen with the state it was last in

This caused me to spend a few hours to find out what went wrong.

So, keep in mind that adb shell am add FLAG_ACTIVITY_NEW_TASK flag.

It's because you have:

def readTTable(fname):
    try:

without a matching except block after the try: block. Every try must have at least one matching except.

See the Errors and Exceptions section of the Python tutorial.

  AND P.shopkeeper = '89137';

You don't need to reinvent the wheel, here's the toArray() method:

String []dsf = new String[al.size()];
al.toArray(dsf);

i encountered this error in quite a stupid way

@Autowired

}

what happened is that I commented a line for some reason and left the annotation which made spring think that the method needs to be autowired

I had the same issue, eventually I found a solution that works without splitting the file, by following Petter Ivarrson's answer

My problem was when converting .p12 certificate to .pem. I used:

openssl pkcs12 -in cert.p12 -out cert.pem

This converts and exports all certificates (CA + CLIENT) together with a private key into one file.

The problem was when I tried to verify if the hashes of certificate and key are matching by running:

// Get certificate HASH
openssl x509 -noout -modulus -in cert.pem | openssl md5

// Get private key HASH
openssl rsa -noout -modulus -in cert.pem | openssl md5

This displayed different hashes and that was the reason CURL failed. See here: https://michaelheap.com/curl-58-unable-to-set-private-key-file-server-key-type-pem/

I guess that was because all certificates are inside a file (CA + CLIENT) and CURL takes CA certificate instead of CLIENT one. Because CA is first in the list.

So the solution was to export only CLIENT certificate together with private key:

openssl pkcs12 -in cert.p12 -out cert.pem -clcerts
``

Now when I re-run the verification:
```sh
openssl x509 -noout -modulus -in cert.pem | openssl md5
openssl rsa -noout -modulus -in cert.pem | openssl md5

HASHES MATCHED !!!

So I was able to make a curl request by running

curl -ivk --cert ./cert.pem:KeyChoosenByMeWhenIrunOpenSSL https://thesite.com

without problems!!!

That being said... I think the best solution is to split the certificates into separate file and use them separately like Petter Ivarsson wrote:

curl --insecure --key key.pem --cacert ca.pem --cert client.pem:KeyChoosenByMeWhenIrunOpenSSL https://thesite.com

Ordinary javascript cannot close windows willy-nilly. This is a security feature, introduced a while ago, to stop various malicious exploits and annoyances.

From the latest working spec for window.close():

The close() method on Window objects should, if all the following conditions are met, close the browsing context A:

• The corresponding browsing context A is script-closable.
• The browsing context of the incumbent script is familiar with the browsing context A.
• The browsing context of the incumbent script is allowed to navigate the browsing context A.

A browsing context is script-closable if it is an auxiliary browsing context that was created by a script (as opposed to by an action of the user), or if it is a browsing context whose session history contains only one Document.

This means, with one small exception, javascript must not be allowed to close a window that was not opened by that same javascript.

Chrome allows that exception -- which it doesn't apply to userscripts -- however Firefox does not. The Firefox implementation flat out states:

This method is only allowed to be called for windows that were opened by a script using the window.open method.

If you try to use window.close from a Greasemonkey / Tampermonkey / userscript you will get:
Firefox: The error message, "Scripts may not close windows that were not opened by script."
Chrome: just silently fails.

The long-term solution:

The best way to deal with this is to make a Chrome extension and/or Firefox add-on instead. These can reliably close the current window.

However, since the security risks, posed by window.close, are much less for a Greasemonkey/Tampermonkey script; Greasemonkey and Tampermonkey could reasonably provide this functionality in their API (essentially packaging the extension work for you).
Consider making a feature request.

The hacky workarounds:

Chrome is currently was vulnerable to the "self redirection" exploit. So code like this used to work in general:

open(location, '_self').close();

This is buggy behavior, IMO, and is now (as of roughly April 2015) mostly blocked. It will still work from injected code only if the tab is freshly opened and has no pages in the browsing history. So it's only useful in a very small set of circumstances.

However, a variation still works on Chrome (v43 & v44) plus Tampermonkey (v3.11 or later). Use an explicit @grant and plain window.close(). EG:

// ==UserScript==
// @name        window.close demo
// @include     http://YOUR_SERVER.COM/YOUR_PATH/*
// @grant       GM_addStyle
// ==/UserScript==

setTimeout (window.close, 5000);

Thanks to zanetu for the update. Note that this will not work if there is only one tab open. It only closes additional tabs.

Firefox is secure against that exploit. So, the only javascript way is to cripple the security settings, one browser at a time.

You can open up about:config and set
allow_scripts_to_close_windows to true.

If your script is for personal use, go ahead and do that. If you ask anyone else to turn that setting on, they would be smart, and justified, to decline with prejudice.

There currently is no equivalent setting for Chrome.

Felt compelled to answer this because of the other responses. Use empty() if you can because it covers more bases. Future you will thank me.

For example you will have to do things like isset() && strlen() where instead you could use empty(). Think of it like this empty is like !isset($var) || $var==false

What does this record marking mean? If this is used only for logging purposes, I would use GET and disable all caching, since you want to log every query for this resources. If record marking has another purpose, POST is the way to go. User should know, that his actions effect the system and POST method is a warning.

Just addition to @zirinisp answer.

Create a file, name it UIWindowExtension.swift and paste the following snippet:

import UIKit

public extension UIWindow {
    public var visibleViewController: UIViewController? {
        return UIWindow.getVisibleViewControllerFrom(self.rootViewController)
    }

    public static func getVisibleViewControllerFrom(vc: UIViewController?) -> UIViewController? {
        if let nc = vc as? UINavigationController {
            return UIWindow.getVisibleViewControllerFrom(nc.visibleViewController)
        } else if let tc = vc as? UITabBarController {
            return UIWindow.getVisibleViewControllerFrom(tc.selectedViewController)
        } else {
            if let pvc = vc?.presentedViewController {
                return UIWindow.getVisibleViewControllerFrom(pvc)
            } else {
                return vc
            }
        }
    }
}

func getTopViewController() -> UIViewController? {
    let appDelegate = UIApplication.sharedApplication().delegate
    if let window = appDelegate!.window {
        return window?.visibleViewController
    }
    return nil
}

Use it anywhere as:

if let topVC = getTopViewController() {

}

Thanks to @zirinisp.

I had a moment, so, although you've already accepted an answer, I thought I'd contribute the following:

Number.prototype.between = function(a, b) {_x000D_
  var min = Math.min.apply(Math, [a, b]),_x000D_
    max = Math.max.apply(Math, [a, b]);_x000D_
  return this > min && this < max;_x000D_
};_x000D_
_x000D_
var windowSize = 550;_x000D_
_x000D_
console.log(windowSize.between(500, 600));

JS Fiddle demo.

Or, if you'd prefer to have the option to check a number is in the defined range including the end-points:

Number.prototype.between = function(a, b, inclusive) {_x000D_
  var min = Math.min.apply(Math, [a, b]),_x000D_
    max = Math.max.apply(Math, [a, b]);_x000D_
  return inclusive ? this >= min && this <= max : this > min && this < max;_x000D_
};_x000D_
_x000D_
var windowSize = 500;_x000D_
_x000D_
console.log(windowSize.between(500, 603, true));

JS Fiddle demo.

Edited to add a minor amendment to the above, given that – as noted in the comments –

…Function.prototype.apply() is slow! Besides calling it when you have a fixed amount of arguments is pointless…

it was worth removing the use of Function.prototype.apply(), which yields the amended versions of the above methods, firstly without the 'inclusive' option:

Number.prototype.between = function(a, b) {_x000D_
  var min = Math.min(a, b),_x000D_
    max = Math.max(a, b);_x000D_
_x000D_
  return this > min && this < max;_x000D_
};_x000D_
_x000D_
var windowSize = 550;_x000D_
_x000D_
console.log(windowSize.between(500, 600));

JS Fiddle demo.

And with the 'inclusive' option:

Number.prototype.between = function(a, b, inclusive) {_x000D_
  var min = Math.min(a, b),_x000D_
    max = Math.max(a, b);_x000D_
_x000D_
  return inclusive ? this >= min && this <= max : this > min && this < max;_x000D_
}_x000D_
_x000D_
var windowSize = 500;_x000D_
_x000D_
console.log(windowSize.between(500, 603, true));

JS Fiddle demo.

i didnt see it mentioned, This example will show you the (-) decimal operation for 2 bit values: A-B (only if A contains B)

this operation is needed when we hold an verb in our program that represent bits. sometimes we need to add bits (like above) and sometimes we need to remove bits (if the verb contains then)

111 #decimal 7
-
100 #decimal 4
--------------
011 #decimal 3

with python: 7 & ~4 = 3 (remove from 7 the bits that represent 4)

001 #decimal 1
-
100 #decimal 4
--------------
001 #decimal 1

with python: 1 & ~4 = 1 (remove from 1 the bits that represent 4 - in this case 1 is not 'contains' 4)..

In general the error:

Error: 2006 (CR_SERVER_GONE_ERROR) - MySQL server has gone away

means that the client couldn't send a question to the server.

mysql import

In your specific case while importing the database file via mysql, this most likely mean that some of the queries in the SQL file are too large to import and they couldn't be executed on the server, therefore client fails on the first occurred error.

So you've the following possibilities:

• Add force option (-f) for mysql to proceed and execute rest of the queries.

  This is useful if the database has some large queries related to cache which aren't relevant anyway.

• Increase max_allowed_packet and wait_timeout in your server config (e.g. ~/.my.cnf).

• Dump the database using --skip-extended-insert option to break down the large queries. Then import it again.

• Try applying --max-allowed-packet option for mysql.

Common reasons

In general this error could mean several things, such as:

• a query to the server is incorrect or too large,

  Solution: Increase max_allowed_packet variable.

  • Make sure the variable is under [mysqld] section, not [mysql].

  • Don't afraid to use large numbers for testing (like 1G).

  • Don't forget to restart the MySQL/MariaDB server.

  • Double check the value was set properly by:

    mysql -sve "SELECT @@max_allowed_packet" # or:
    mysql -sve "SHOW VARIABLES LIKE 'max_allowed_packet'"
    

• You got a timeout from the TCP/IP connection on the client side.

  Solution: Increase wait_timeout variable.

• You tried to run a query after the connection to the server has been closed.

  Solution: A logic error in the application should be corrected.

• Host name lookups failed (e.g. DNS server issue), or server has been started with --skip-networking option.

  Another possibility is that your firewall blocks the MySQL port (e.g. 3306 by default).

• The running thread has been killed, so retry again.

• You have encountered a bug where the server died while executing the query.

• A client running on a different host does not have the necessary privileges to connect.

• And many more, so learn more at: B.5.2.9 MySQL server has gone away.

Debugging

Here are few expert-level debug ideas:

• Check the logs, e.g.

  sudo tail -f $(mysql -Nse "SELECT @@GLOBAL.log_error")
  

• Test your connection via mysql, telnet or ping functions (e.g. mysql_ping in PHP).

• Use tcpdump to sniff the MySQL communication (won't work for socket connection), e.g.:

  sudo tcpdump -i lo0 -s 1500 -nl -w- port mysql | strings
  

• On Linux, use strace. On BSD/Mac use dtrace/dtruss, e.g.

  sudo dtruss -a -fn mysqld 2>&1

For reference, check the source code in sql-common/client.c file responsible for throwing the CR_SERVER_GONE_ERROR error for the client command.

MYSQL_TRACE(SEND_COMMAND, mysql, (command, header_length, arg_length, header, arg));
if (net_write_command(net,(uchar) command, header, header_length,
          arg, arg_length))

I know this is 8 years old, but no one seems to have actually read and answered the question.

You can call .values() on a dict to get a list of the inner dicts and thus access them by index.

>>> mydict = {
...  'Apple': {'American':'16', 'Mexican':10, 'Chinese':5},
...  'Grapes':{'Arabian':'25','Indian':'20'} }

>>>mylist = list(mydict.values())
>>>mylist[0]
{'American':'16', 'Mexican':10, 'Chinese':5},
>>>mylist[1]
{'Arabian':'25','Indian':'20'}

>>>myInnerList1 = list(mylist[0].values())
>>>myInnerList1
['16', 10, 5]
>>>myInnerList2 = list(mylist[1].values())
>>>myInnerList2
['25', '20']

Here Is working fiddle

here is another solution...

System.IO.Stream st = new System.IO.StreamReader (picturePath).BaseStream;
byte[] buffer = new byte[4096];

System.IO.MemoryStream m = new System.IO.MemoryStream ();
while (st.Read (buffer,0,buffer.Length) > 0) {
    m.Write (buffer, 0, buffer.Length);
}  
imgView.Tag = m.ToArray ();
st.Close ();
m.Close ();

hope it helps!

Here is an example of how you can do it in "classic" R graphics:

## generate some random data
carrotLengths <- rnorm(1000,15,5)
cucumberLengths <- rnorm(200,20,7)
## calculate the histograms - don't plot yet
histCarrot <- hist(carrotLengths,plot = FALSE)
histCucumber <- hist(cucumberLengths,plot = FALSE)
## calculate the range of the graph
xlim <- range(histCucumber$breaks,histCarrot$breaks)
ylim <- range(0,histCucumber$density,
              histCarrot$density)
## plot the first graph
plot(histCarrot,xlim = xlim, ylim = ylim,
     col = rgb(1,0,0,0.4),xlab = 'Lengths',
     freq = FALSE, ## relative, not absolute frequency
     main = 'Distribution of carrots and cucumbers')
## plot the second graph on top of this
opar <- par(new = FALSE)
plot(histCucumber,xlim = xlim, ylim = ylim,
     xaxt = 'n', yaxt = 'n', ## don't add axes
     col = rgb(0,0,1,0.4), add = TRUE,
     freq = FALSE) ## relative, not absolute frequency
## add a legend in the corner
legend('topleft',c('Carrots','Cucumbers'),
       fill = rgb(1:0,0,0:1,0.4), bty = 'n',
       border = NA)
par(opar)

The only issue with this is that it looks much better if the histogram breaks are aligned, which may have to be done manually (in the arguments passed to hist).

concat also works nicely with a list comprehension pulled using the "loc" command against an existing dataframe

df = pd.read_csv('./data.csv') # ie; Dataframe pulled from csv file with a "userID" column

review_ids = ['1','2','3'] # ie; ID values to grab from DataFrame

# Gets rows in df where IDs match in the userID column and combines them 

dfa = pd.concat([df.loc[df['userID'] == x] for x in review_ids])

import numpy as np

df['New_ID']=np.arange(880,880+len(df.Fruit))
df=df.reindex(columns=['New_ID','ID','Fruit'])

For me just adding the "LOCAL" Keyword did the trick, please see the attached image for easier solution.

My attached image contains both use cases:

(a) Where I was getting this error. (b) Where error was resolved by just adding "Local" keyword.

Just put DROP TABLE IF EXISTS `tablename`; before your CREATE TABLE statement.

That statement drops the table if it exists but will not throw an error if it does not.

Beware that when the mounted event is fired on a component, not all Vue components are replaced yet, so the DOM may not be final yet.

To really simulate the DOM onload event, i.e. to fire after the DOM is ready but before the page is drawn, use vm.$nextTick from inside mounted:

mounted: function () {
  this.$nextTick(function () {
    // Will be executed when the DOM is ready
  })
}

Whenever is possible is preferable to use class .myclass{} and identifier #myclass{}, so use a dedicated css file or tag <style></style> within an html. Inline style is good to change css option dynamically with javascript.

Consider each row as a column, and each column as a row .. use j,i instead of i,j

demo: http://ideone.com/lvsxKZ

#include <iostream> 
using namespace std;

int main ()
{
    char A [3][3] =
    {
        { 'a', 'b', 'c' },
        { 'd', 'e', 'f' },
        { 'g', 'h', 'i' }
    };

    cout << "A = " << endl << endl;

    // print matrix A
    for (int i=0; i<3; i++)
    {
        for (int j=0; j<3; j++) cout << A[i][j];
        cout << endl;
    }

    cout << endl << "A transpose = " << endl << endl;

    // print A transpose
    for (int i=0; i<3; i++)
    {
        for (int j=0; j<3; j++) cout << A[j][i];
        cout << endl;
    }

    return 0;
}

Solved by installing the latest mySQL release, following the instructions here http://coolestguidesontheplanet.com/get-apache-mysql-php-phpmyadmin-working-osx-10-10-yosemite/

EDIT
As Yosemite gets more popular, more people are stumbling on this question. The answer above has to do with upgrading MySQL, so that it runs. The answer linked by @doc in the comments has to do with getting MySQL to start automatically. These are 2 separate issues.

This questions is already answered here. Just put height: 100% in both the div and the container td.

You can just do:

df[sorted(df.columns)]

Edit: Shorter is

df[sorted(df)]

It is difficult to choose which one is better; lock or ReaderWriterLockSlim. You need real world statistics of read and write numbers and ratios etc.

But if you believe using "lock" is the correct way. Then here is a different solution for different needs. I also include the Allan Xu's solution in the code. Because both can be needed for different needs.

Here are the requirements, driving me to this solution:

1. You don't want to or cannot supply the 'GetData' function for some reason. Perhaps the 'GetData' function is located in some other class with a heavy constructor and you do not want to even create an instance till ensuring it is unescapable.
2. You need to access the same cached data from different locations/tiers of the application. And those different locations don't have access to same locker object.
3. You don't have a constant cache key. For example; need of caching some data with the sessionId cache key.

Code:

using System;
using System.Runtime.Caching;
using System.Collections.Concurrent;
using System.Collections.Generic;

namespace CachePoc
{
    class Program
    {
        static object everoneUseThisLockObject4CacheXYZ = new object();
        const string CacheXYZ = "CacheXYZ";
        static object everoneUseThisLockObject4CacheABC = new object();
        const string CacheABC = "CacheABC";

        static void Main(string[] args)
        {
            //Allan Xu's usage
            string xyzData = MemoryCacheHelper.GetCachedDataOrAdd<string>(CacheXYZ, everoneUseThisLockObject4CacheXYZ, 20, SomeHeavyAndExpensiveXYZCalculation);
            string abcData = MemoryCacheHelper.GetCachedDataOrAdd<string>(CacheABC, everoneUseThisLockObject4CacheXYZ, 20, SomeHeavyAndExpensiveXYZCalculation);

            //My usage
            string sessionId = System.Web.HttpContext.Current.Session["CurrentUser.SessionId"].ToString();
            string yvz = MemoryCacheHelper.GetCachedData<string>(sessionId);
            if (string.IsNullOrWhiteSpace(yvz))
            {
                object locker = MemoryCacheHelper.GetLocker(sessionId);
                lock (locker)
                {
                    yvz = MemoryCacheHelper.GetCachedData<string>(sessionId);
                    if (string.IsNullOrWhiteSpace(yvz))

                        MemoryCacheHelper.AddDataToCache(sessionId, yvz, 5);
                    }
                }
            }
        }

            //Allan Xu's solution
            public static T GetCachedDataOrAdd<T>(string cacheKey, object cacheLock, int minutesToExpire, Func<T> GetData) where T : class
            {
                //Returns null if the string does not exist, prevents a race condition where the cache invalidates between the contains check and the retreival.
                T cachedData = MemoryCache.Default.Get(cacheKey, null) as T;

                if (cachedData != null)

It's a design pattern and it's not specific to c#. More about it all over the internet and SO, like on this wikipedia article.

In software engineering, the singleton pattern is a design pattern that is used to restrict instantiation of a class to one object. This is useful when exactly one object is needed to coordinate actions across the system. The concept is sometimes generalized to systems that operate more efficiently when only one object exists, or that restrict the instantiation to a certain number of objects (say, five). Some consider it an anti-pattern, judging that it is overused, introduces unnecessary limitations in situations where a sole instance of a class is not actually required, and introduces global state into an application.

You should use it if you want a class that can only be instanciated once.

The Cloud Under blog has a good explanation of CSRF tokens. (archived)

Imagine you had a website like a simplified Twitter, hosted on a.com. Signed in users can enter some text (a tweet) into a form that’s being sent to the server as a POST request and published when they hit the submit button. On the server the user is identified by a cookie containing their unique session ID, so your server knows who posted the Tweet.

The form could be as simple as that:

 <form action="http://a.com/tweet" method="POST">
   <input type="text" name="tweet">
   <input type="submit">
 </form> 

Now imagine, a bad guy copies and pastes this form to his malicious website, let’s say b.com. The form would still work. As long

as a user is signed in to your Twitter (i.e. they’ve got a valid session cookie for a.com), the POST request would be sent to http://a.com/tweet and processed as usual when the user clicks the submit button.

So far this is not a big issue as long as the user is made aware about what the form exactly does, but what if our bad guy tweaks the form like this:

 <form action="https://example.com/tweet" method="POST">
   <input type="hidden" name="tweet" value="Buy great products at http://b.com/#iambad">
   <input type="submit" value="Click to win!">
 </form> 

Now, if one of your users ends up on the bad guy’s website and hits the “Click to win!” button, the form is submitted to

your website, the user is correctly identified by the session ID in the cookie and the hidden Tweet gets published.

If our bad guy was even worse, he would make the innocent user submit this form as soon they open his web page using JavaScript, maybe even completely hidden away in an invisible iframe. This basically is cross-site request forgery.

A form can easily be submitted from everywhere to everywhere. Generally that’s a common feature, but there are many more cases where it’s important to only allow a form being submitted from the domain where it belongs to.

Things are even worse if your web application doesn’t distinguish between POST and GET requests (e.g. in PHP by using $_REQUEST instead of $_POST). Don’t do that! Data altering requests could be submitted as easy as <img src="http://a.com/tweet?tweet=This+is+really+bad">, embedded in a malicious website or even an email.

How do I make sure a form can only be submitted from my own website? This is where the CSRF token comes in. A CSRF token is a random, hard-to-guess string. On a page with a form you want to protect, the server would generate a random string, the CSRF token, add it to the form as a hidden field and also remember it somehow, either by storing it in the session or by setting a cookie containing the value. Now the form would look like this:

    <form action="https://example.com/tweet" method="POST">
      <input type="hidden" name="csrf-token" value="nc98P987bcpncYhoadjoiydc9ajDlcn">
      <input type="text" name="tweet">
      <input type="submit">
    </form> 

When the user submits the form, the server simply has to compare the value of the posted field csrf-token (the name doesn’t

matter) with the CSRF token remembered by the server. If both strings are equal, the server may continue to process the form. Otherwise the server should immediately stop processing the form and respond with an error.

Why does this work? There are several reasons why the bad guy from our example above is unable to obtain the CSRF token:

Copying the static source code from our page to a different website would be useless, because the value of the hidden field changes with each user. Without the bad guy’s website knowing the current user’s CSRF token your server would always reject the POST request.

Because the bad guy’s malicious page is loaded by your user’s browser from a different domain (b.com instead of a.com), the bad guy has no chance to code a JavaScript, that loads the content and therefore our user’s current CSRF token from your website. That is because web browsers don’t allow cross-domain AJAX requests by default.

The bad guy is also unable to access the cookie set by your server, because the domains wouldn’t match.

When should I protect against cross-site request forgery? If you can ensure that you don’t mix up GET, POST and other request methods as described above, a good start would be to protect all POST requests by default.

You don’t have to protect PUT and DELETE requests, because as explained above, a standard HTML form cannot be submitted by a browser using those methods.

JavaScript on the other hand can indeed make other types of requests, e.g. using jQuery’s $.ajax() function, but remember, for AJAX requests to work the domains must match (as long as you don’t explicitly configure your web server otherwise).

This means, often you do not even have to add a CSRF token to AJAX requests, even if they are POST requests, but you will have to make sure that you only bypass the CSRF check in your web application if the POST request is actually an AJAX request. You can do that by looking for the presence of a header like X-Requested-With, which AJAX requests usually include. You could also set another custom header and check for its presence on the server side. That’s safe, because a browser would not add custom headers to a regular HTML form submission (see above), so no chance for Mr Bad Guy to simulate this behaviour with a form.

If you’re in doubt about AJAX requests, because for some reason you cannot check for a header like X-Requested-With, simply pass the generated CSRF token to your JavaScript and add the token to the AJAX request. There are several ways of doing this; either add it to the payload just like a regular HTML form would, or add a custom header to the AJAX request. As long as your server knows where to look for it in an incoming request and is able to compare it to the original value it remembers from the session or cookie, you’re sorted.

That means that the definition of your function is not present in your program. You forgot to add that one.cpp to your program.

What "to add" means in this case depends on your build environment and its terminology. In MSVC (since you are apparently use MSVC) you'd have to add one.cpp to the project.

In more practical terms, applicable to all typical build methodologies, when you link you program, the object file created form one.cpp is missing.

If you're just stripping name spaces and want anything after the last \ in a class name with namespace (or just the name if there's no '\') you can do something like this:

$base_class = preg_replace('/^([\w\\\\]+\\\\)?([^\\\\]+)$/', '$2', get_class($myobject));

Basically it's regex to get any combination of characters or backslashes up and until the last backslash then to return only the non-backslash characters up and until the end of the string. Adding the ? after the first grouping means if the pattern match doesn't exist, it just returns the full string.

To elaborate more on some answers that have mentioned -webkit-text-stroke, here's is the code to make it work:

div {
  -webkit-text-fill-color: black;
  -webkit-text-stroke-color: red;
  -webkit-text-stroke-width: 2.00px; 
}

An in-depth article about using text stroke is here and a list of browsers that support text stroke is here.

Getting one month ago is easy with a single MySQL function:

SELECT DATE_SUB(NOW(), INTERVAL 1 MONTH);

or

SELECT NOW() - INTERVAL 1 MONTH;

Off the top of my head, I can't think of an elegant way to get the first day of last month in MySQL, but this will certainly work:

SELECT CONCAT(LEFT(NOW() - INTERVAL 1 MONTH,7),'-01');

Put them together and you get a query that solves your problem:

SELECT *
FROM your_table
WHERE t >= CONCAT(LEFT(NOW() - INTERVAL 1 MONTH,7),'-01')
AND t <= NOW() - INTERVAL 1 MONTH

all, I solved a problem and wanted to share it:

I had this error <> The issue was in that in my statement:

alter table system_registro_de_modificacion add foreign key (usuariomodificador_id) REFERENCES Usuario(id) On delete restrict;

I had incorrectly written the CASING: it works in Windows WAMP, but in Linux MySQL it is more strict with the CASING, so writting "Usuario" instead of "usuario" (exact casing), generated the error, and was corrected simply changing the casing.

Simply pass view object into onButtonClicked function. getView() does not seem to work as expected inside fragment. Try this code for your FragmentOne fragment

PS. you have redefined object view in your original FragmentOne code.

package com.example.fragmenttutorial;

import android.app.Fragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class FragmentOne extends Fragment{

    FragmentManager fragmentManager = getFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.fragment_one, container, false);
        onButtonClicked(view);
        return view;
    }

  protected void onButtonClicked(View view)
  {
      if(view.getId() == R.id.buttonSayHi){
          Fragment fragmentTwo = new FragmentTwo();

          fragmentTransaction.replace(R.id.frameLayoutFragmentContainer, fragmentTwo);
          fragmentTransaction.addToBackStack(null);

          fragmentTransaction.commit();   

     }

I've found that you cannot set a gradient with background-color.

This works:

background:linear-gradient(to right, rgba(255,0,0,0), rgba(255,255,255,1));

This doesn't:

background-color:linear-gradient(to right, rgba(255,0,0,0), rgba(255,255,255,1));

Here's a simple way using OLINQ:

// Input array
List<String> lst = new List<string>();
for (int i = 0; i < 500; i += 1) lst.Add(i.ToString());

// Output array
List<String> lstRandom = new List<string>();

// Randomize
Random rnd = new Random();
lstRandom.AddRange(from s in lst orderby rnd.Next(100) select s);

Use this command, (go to java < jdk < bin path in cmd prompt)

$ jarsigner -verify -verbose -certs my_application.apk

If you see "CN=Android Debug", this means the .apk was signed with the debug key generated by the Android SDK (means it is unsigned), otherwise you will find something for CN. For more details see: http://developer.android.com/guide/publishing/app-signing.html

Don't enter the password with command. Just enter,

mysqldump -u <username> -p <db_name> > <backup_file>.sql

Then you will get a prompt to enter password.

Just download curl and extract the compressed file. You will get the file "curl.exe". Open a CMD Shell, drag the file curl.exe into the CMD Shell, now you can use curl.

Try this:

$old_date = Date_create("2010-04-19 18:31:27");
$new_date = Date_format($old_date, "d/m/Y");

In latest IntelliJ versions, you should run it from Analyze->Run Inspection By Name:

Than, pick Unused declaration:

And finally, uncheck the Include test sources:

A 2-tuple is a pair. You can access the first and second elements like this:

x = ('a', 1) # make a pair
x[0] # access 'a'
x[1] # access 1

I faced similar scenario. It was happening because classA's initilization was dependent on classB's initialization. When classB's static block faced runtime exception, classB was not initialized. Because of this, classB did not throw any exception and classA's initialization failed too.

class A{//this class will never be initialized because class B won't intialize
  static{
    try{
      classB.someStaticMethod();
    }catch(Exception e){
      sysout("This comment will never be printed");
    }
 }
}

class B{//this class will never be initialized
 static{
    int i = 1/0;//throw run time exception 
 }

 public static void someStaticMethod(){}
}

And yes...catching Exception will catch run time exceptions as well.

By regex i think this is java, the method replaceAll() returns a new String with the substrings replaced, so try this:

String teste = "abcd=0; efgh=1";

String teste2 = teste.replaceAll("abcd", "dddd");

System.out.println(teste2);

Output:

dddd=0; efgh=1

As far as I'm aware you have to still write the application using a form, but have no controls on the form and never set it visible. Use the NotifyIcon (an MSDN sample of which can be found here) to write your application.

You can use the following.

@using (Html.BeginForm("MyAction", "MyController", new { area = "MyArea" }, FormMethod.Post, new { @class = "" }))
{
<div class="col-md-6">
    <div class="col-lg-3 col-md-3 col-sm-3 col-xs-12">
        @Html.LabelFor(m => m.MyData, new { @class = "col-form-label" })
    </div>
    <div class="col-lg-9 col-md-9 col-sm-9 col-xs-12">
        @Html.TextBoxFor(m => m.MyData, new { @class = "form-control" })
    </div>
</div>
<div class="col-md-6">
    <div class="">
        <button class="btn btn-primary" type="submit">Send</button>
        <button class="btn btn-danger" type="reset"> Clear</button>
    </div>
</div>
}

Then clear the form:

    $('.btn:reset').click(function (ev) {
        ev.preventDefault();
        $(this).closest('form').find("input").each(function(i, v) {
            $(this).val("");
        });
    });

For my case increasing the memory using -Xmx option was the solution.

I had a 10g file read in java and each time I got the same error. This happened when the value in the RES column in top command reached to the value set in -Xmx option. Then by increasing the memory using -Xmx option everything went fine.

There was another point as well. When I set JAVA_OPTS or CATALINA_OPTS in my user account and increased the amount of memory again I got the same error. Then, I printed the value of those environment variables in my code which gave me different values than what I set. The reason was that Tomcat was the root for that process and then as I was not a su-doer I asked the admin to increase the memory in catalina.sh in Tomcat.

Swift makes it really easy to create and use extensions. I create a sharedCode.swift file and put enums, extensions, and other fun stuff in it. I created a NSDate extension to add some typical functionality which is laborious and ugly to type over and over again:

extension NSDate
{
    func hour() -> Int
    {
        //Get Hour
        let calendar = NSCalendar.currentCalendar()
        let components = calendar.components(.Hour, fromDate: self)
        let hour = components.hour

        //Return Hour
        return hour
    }


    func minute() -> Int
    {
        //Get Minute
        let calendar = NSCalendar.currentCalendar()
        let components = calendar.components(.Minute, fromDate: self)
        let minute = components.minute

        //Return Minute
        return minute
    }

    func toShortTimeString() -> String
    {
        //Get Short Time String
        let formatter = NSDateFormatter()
        formatter.timeStyle = .ShortStyle
        let timeString = formatter.stringFromDate(self)

        //Return Short Time String
        return timeString
    }
}

using this extension you can now do something like:

        //Get Current Date
        let currentDate = NSDate()

        //Test Extensions in Log
        NSLog("(Current Hour = \(currentDate.hour())) (Current Minute = \(currentDate.minute())) (Current Short Time String = \(currentDate.toShortTimeString()))")

Which for 11:51 AM would write out:

(Current Hour = 11) (Current Minute = 51) (Current Short Time String = 11:51 AM)

Use immediate children selector >:

$('#tblOne > tbody  > tr')

Description: Selects all direct child elements specified by "child" of elements specified by "parent".

You can try using https://ip-api.io - geo location api that returns country among other IP information.

For example with Node.js

const request = require('request-promise')

request('http://ip-api.io/api/json/1.2.3.4')
  .then(response => console.log(JSON.parse(response)))
  .catch(err => console.log(err))

For the less specific case (not just the code in the question - since this is one of the first results in Google for this generic error message. This error also occurs when running certain os command with None argument.

For example:

os.path.exists(arg)  
os.stat(arg)

Will raise this exception when arg is None.

If you are in SQL*Plus or SQL Developer, you want to run

SQL> set define off;

before executing the SQL statement. That turns off the checking for substitution variables.

SET directives like this are instructions for the client tool (SQL*Plus or SQL Developer). They have session scope, so you would have to issue the directive every time you connect (you can put the directive in your client machine's glogin.sql if you want to change the default to have DEFINE set to OFF). There is no risk that you would impact any other user or session in the database.

IMHO for Angular2 (v2.2.3) the best way is to add services that contain the global variable and inject them into components without the providers tag inside the @Component annotation. By this way you are able to share information between components.

A sample service that owns a global variable:

import { Injectable } from '@angular/core'

@Injectable()
export class SomeSharedService {
  public globalVar = '';
}

A sample component that updates the value of your global variable:

import { SomeSharedService } from '../services/index';

@Component({
  templateUrl: '...'
})
export class UpdatingComponent {

  constructor(private someSharedService: SomeSharedService) { }

  updateValue() {
    this.someSharedService.globalVar = 'updated value';
  }
}

A sample component that reads the value of your global variable:

import { SomeSharedService } from '../services/index';

@Component({
  templateUrl: '...'
})
export class ReadingComponent {

  constructor(private someSharedService: SomeSharedService) { }

  readValue() {
    let valueReadOut = this.someSharedService.globalVar;
    // do something with the value read out
  }
}

Note that providers: [ SomeSharedService ] should not be added to your @Component annotation. By not adding this line injection will always give you the same instance of SomeSharedService. If you add the line a freshly created instance is injected.

I have done this in a project a long time ago. The code given below write a whole rows bold with specific column names and all of these columns are written in bold format.

private void WriteColumnHeaders(DataColumnCollection columnCollection, int row, int column)
    {
        // row represent particular row you want to bold its content.
        for (i = 0; i < columnCollection.Count; i++)
        {
            DataColumn col = columnCollection[i];
            xlWorkSheet.Cells[row, column + i + 1] = col.Caption;
            // Some Font Styles
            xlWorkSheet.Cells[row, column + i + 1].Style.Font.Bold = true;
            xlWorkSheet.Cells[row, column + i + 1].Interior.Color = Color.FromArgb(192, 192, 192);
            //xlWorkSheet.Columns[i + 1].ColumnWidth = xlWorkSheet.Columns[i+1].ColumnWidth + 10;
        }
    }

You must pass value of row 0 so that first row of your excel sheets have column headers with bold font size. Just change DataColumnCollection to your columns name and change col.Caption to specific column name.

Alternate

You may do this to cell of excel sheet you want bold.

xlWorkSheet.Cells[row, column].Style.Font.Bold = true;

You need to add use Response; facade in header at your file.

Only then you can successfully retrieve your data with

return Response::json($data);

As other answers have specified, be sure to use explode rather than split because as of PHP 5.3.0 split is deprecated. i.e. the following is NOT the way you want to do it:

$your_array = split(chr(10), $your_string);

LF = "\n" = chr(10), CR = "\r" = chr(13)

</anti-answer>

You can convert a datetime object to a date with the date() method of the date time object, as follows:

<datetime_object>.date()

You can also change the data type to bigInt and it will solve your problem, it's not a good practice to keep integers as strings unless needed. :)

ALTER TABLE T_PERSON MODIFY mobile_no BIGINT;

On many source packages (e.g. for most GNU software), the building system may know about the DESTDIR make variable, so you can often do:

 make install DESTDIR=/tmp/myinst/
 sudo cp -va /tmp/myinst/ /

The advantage of this approach is that make install don't need to run as root, so you cannot end up with files compiled as root (or root-owned files in your build tree).

Try Below Simple Ruby Magics :)

(1..x).each { |n| puts n }
x.times { |n| puts n }
1.upto(x) { |n| print n }

If you want to do an executable jar file, them need set the main class too. So the full configuration should be.

    <plugins>
            <plugin>
                 <artifactId>maven-assembly-plugin</artifactId>
                 <executions>
                     <execution>
                          <phase>package</phase>
                          <goals>
                              <goal>single</goal>
                          </goals>
                      </execution>
                  </executions>
                  <configuration>
                       <!-- ... -->
                       <archive>
                           <manifest>
                                 <mainClass>fully.qualified.MainClass</mainClass>
                           </manifest>
                       </archive>
                       <descriptorRefs>
                           <descriptorRef>jar-with-dependencies</descriptorRef>
                      </descriptorRefs>
                 </configuration>
         </plugin>
   </plugins>

You can do that for your entire script by using something like that at the beginning of your script :

#!/usr/bin/env bash

test x$1 = x$'\x00' && shift || { set -o pipefail ; ( exec 2>&1 ; $0 $'\x00' "$@" ) | tee mylogfile ; exit $? ; }

# do whaetever you want

This redirect both stderr and stdout outputs to the file called mylogfile and let everything goes to stdout at the same time.

It is used some stupid tricks :

• use exec without command to setup redirections,
• use tee to duplicates outputs,
• restart the script with the wanted redirections,
• use a special first parameter (a simple NUL character specified by the $'string' special bash notation) to specify that the script is restarted (no equivalent parameter may be used by your original work),
• try to preserve the original exit status when restarting the script using the pipefail option.

Ugly but useful for me in certain situations.

I use

            chartRange = xlWorkSheet.Rows[1];
            chartRange.Font.Bold = true;

to turn the first-row-cells-font into bold. And it works, and I am using also Excel 2007.

You can call in VBA directly

            ActiveCell.Font.Bold = True

With this code I create a timestamp in the active cell, with bold font and yellow background

           Private Sub Worksheet_SelectionChange(ByVal Target As Range)
               ActiveCell.Value = Now()
               ActiveCell.Font.Bold = True
               ActiveCell.Interior.ColorIndex = 6
           End Sub

You can use:

NOW() + INTERVAL 1 DAY

If you are only interested in the date, not the date and time then you can use CURDATE instead of NOW:

CURDATE() + INTERVAL 1 DAY

Maybe you can try the following :

var i = 0;
function AjaxSendForm(url, placeholder, form, append) {
var data = $(form).serialize();
append = (append === undefined ? false : true); // whatever, it will evaluate to true or false only
$.ajax({
    type: 'POST',
    url: url,
    data: data,
    beforeSend: function() {
        // setting a timeout
        $(placeholder).addClass('loading');
        i++;
    },
    success: function(data) {
        if (append) {
            $(placeholder).append(data);
        } else {
            $(placeholder).html(data);
        }
    },
    error: function(xhr) { // if error occured
        alert("Error occured.please try again");
        $(placeholder).append(xhr.statusText + xhr.responseText);
        $(placeholder).removeClass('loading');
    },
    complete: function() {
        i--;
        if (i <= 0) {
            $(placeholder).removeClass('loading');
        }
    },
    dataType: 'html'
});
}

This way, if the beforeSend statement is called before the complete statement i will be greater than 0 so it will not remove the class. Then only the last call will be able to remove it.

I cannot test it, let me know if it works or not.

Difference Between ClassNotFoundException Vs NoClassDefFoundError

when you are using 32bits node on 64bits windows(like node-webkit or atom-shell developers), process.platform will echo win32

use

This is my Save Attachments script. You select all the messages that you want the attachments saved from, and it will save a copy there. It also adds text to the message body indicating where the attachment is saved. You could easily change the folder name to include the date, but you would need to make sure the folder existed before starting to save files.

Easily readable and customisable way to get a timestamp in your desired format, without use of any library:

function timestamp(){
  function pad(n) {return n<10 ? "0"+n : n}
  d=new Date()
  dash="-"
  colon=":"
  return d.getFullYear()+dash+
  pad(d.getMonth()+1)+dash+
  pad(d.getDate())+" "+
  pad(d.getHours())+colon+
  pad(d.getMinutes())+colon+
  pad(d.getSeconds())
}

(If you require time in UTC format, then just change the function calls. For example "getMonth" becomes "getUTCMonth")

fix json values, it's add \ before u{xxx} to all +" "

  $item = preg_replace_callback('/"(.+?)":"(u.+?)",/', function ($matches) {
        $matches[2] = preg_replace('/(u)/', '\u', $matches[2]);
            $matches[2] = preg_replace('/(")/', '"', $matches[2]); 
            $matches[2] = json_decode('"' . $matches[2] . '"'); 
            return '"' . $matches[1] . '":"' . $matches[2] . '",';
        }, $item);

To add characters such as T and Z in your date

@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss'Z'")
private Date currentTime;

output

{
    "currentTime": "2019-12-11T11:40:49Z"
}

The REST camp have some guiding principles that we can use to standardize the way we use HTTP verbs. This is helpful when building RESTful API's as you are doing.

In a nutshell: GET should be Read Only i.e. have no effect on server state. POST is used to create a resource on the server. PUT is used to update or create a resource. DELETE is used to delete a resource.

In other words, if your API action changes the server state, REST advises us to use POST/PUT/DELETE, but not GET.

User agents usually understand that doing multiple POSTs is bad and will warn against it, because the intent of POST is to alter server state (eg. pay for goods at checkout), and you probably don't want to do that twice!

Compare to a GET which you can do an often as you like (idempotent).

You may also need to specify the proxy server/port, in some environments the system settings for proxy are not enough for npm to work.

    npm config set proxy "http://your-proxy.com:80"

In relative layout you need specify textview height:

android:layout_height="100dp"

Or specify lines attribute:

android:lines="3"

See this:

The difference between Response.Write() and Response.Output.Write() in ASP.NET. The short answer is that the latter gives you String.Format-style output and the former doesn't. The long answer follows.

In ASP.NET the Response object is of type HttpResponse and when you say Response.Write you're really saying (basically) HttpContext.Current.Response.Write and calling one of the many overloaded Write methods of HttpResponse.

Response.Write then calls .Write() on it's internal TextWriter object:

public void Write(object obj){ this._writer.Write(obj);} 

HttpResponse also has a Property called Output that is of type, yes, TextWriter, so:

public TextWriter get_Output(){ return this._writer; } 

Which means you can do the Response whatever a TextWriter will let you. Now, TextWriters support a Write() method aka String.Format, so you can do this:

Response.Output.Write("Scott is {0} at {1:d}", "cool",DateTime.Now);

But internally, of course, this is happening:

public virtual void Write(string format, params object[] arg)
{ 
this.Write(string.Format(format, arg)); 
}

On unix, you can use the ps tool to monitor it:

$ ps u -p 1347 | awk '{sum=sum+$6}; END {print sum/1024}'

where 1347 is some process id. Also, the result is in MB.

One of the reasons why everyone has a slightly different definition is because Subversion implements zero support for branches and tags. Subversion basically says: We looked at full-featured branches and tags in other systems and did not found them useful, so we did not implement anything. Just make a copy into a new directory with a name convention instead. Then of course everyone is free to have slightly different conventions. To understand the difference between a real tag and a mere copy + naming convention see the Wikipedia entry Subversion tags & branches.

There is an isConnected function in BluetoothDevice system API in https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/BluetoothDevice.java

If you want to know if the a bounded(paired) device is currently connected or not, the following function works fine for me:

public static boolean isConnected(BluetoothDevice device) {
    try {
        Method m = device.getClass().getMethod("isConnected", (Class[]) null);
        boolean connected = (boolean) m.invoke(device, (Object[]) null);
        return connected;
    } catch (Exception e) {
        throw new IllegalStateException(e);
    }
}

Ok, I solved it by adding the url for the background image at the end of the line.

Here's my working code:

just add following line in wamp/alias/phpmyadmin.conf
Allow from ::1

so it will look something like this depending your phpmyadmin version.

AllowOverride all
    Order Deny,Allow
Deny from all
Allow from 127.0.0.1

It's certainly possible to grab a screenshot using the .NET Framework. The simplest way is to create a new Bitmap object and draw into that using the Graphics.CopyFromScreen method.

Sample code:

using (Bitmap bmpScreenCapture = new Bitmap(Screen.PrimaryScreen.Bounds.Width, 
                                            Screen.PrimaryScreen.Bounds.Height))
using (Graphics g = Graphics.FromImage(bmpScreenCapture))
{
    g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
                     Screen.PrimaryScreen.Bounds.Y,
                     0, 0,
                     bmpScreenCapture.Size,
                     CopyPixelOperation.SourceCopy);
}

Caveat: This method doesn't work properly for layered windows. Hans Passant's answer here explains the more complicated method required to get those in your screen shots.

Another option:

names = repmat({'Sample Text'}, 10, 1)

I changed 3 things and then it works:

1. There is a column of spaces, I removed them
2. Changed the line break from windows CRLF to linux LF
3. Removed the empty line at the end.

When we create a static variable or method it is stored in the special area on heap: PermGen(Permanent Generation), where it lays down with all the data applying to classes(non-instance data). Starting from Java 8 the PermGen became - Metaspace. The difference is that Metaspace is auto-growing space, while PermGen has a fixed Max size, and this space is shared among all of the instances. Plus the Metaspace is a part of a Native Memory and not JVM Memory.

You can look into this for more details.

I know the question specified dplyr. But, since others already posted solutions using other packages, I decided to have a go using other packages too:

Base package:

df <- df[with(df, order(id, stopSequence, stopId)), ]
merge(df[!duplicated(df$id), ], 
      df[!duplicated(df$id, fromLast = TRUE), ], 
      all = TRUE)

data.table:

df <-  setDT(df)
df[order(id, stopSequence)][, .SD[c(1,.N)], by=id]

sqldf:

library(sqldf)
min <- sqldf("SELECT id, stopId, min(stopSequence) AS StopSequence
      FROM df GROUP BY id 
      ORDER BY id, StopSequence, stopId")
max <- sqldf("SELECT id, stopId, max(stopSequence) AS StopSequence
      FROM df GROUP BY id 
      ORDER BY id, StopSequence, stopId")
sqldf("SELECT * FROM min
      UNION
      SELECT * FROM max")

In one query:

sqldf("SELECT * 
        FROM (SELECT id, stopId, min(stopSequence) AS StopSequence
              FROM df GROUP BY id 
              ORDER BY id, StopSequence, stopId)
        UNION
        SELECT *
        FROM (SELECT id, stopId, max(stopSequence) AS StopSequence
              FROM df GROUP BY id 
              ORDER BY id, StopSequence, stopId)")

Output:

  id stopId StopSequence
1  1      a            1
2  1      c            3
3  2      b            1
4  2      c            4
5  3      a            3
6  3      b            1

echo $select->getSqlString()

Here's is a way of doing it without any Javascript and it's also compatible with any browser.

EDIT: In Safari, the input gets disabled when hidden with display: none. A better approach would be to use position: fixed; top: -100em.

<label>
  Open file dialog
  <input type="file" style="position: fixed; top: -100em">
</label>

Also, if you prefer you can go the "correct way" by using for in the label pointing to the id of the input like this:

<label for="inputId">file dialog</label>
<input id="inputId" type="file" style="position: fixed; top: -100em">

Since you're already using Google's Json-Simple library, you can parse the json from an InputStream like this:

InputStream inputStream = ... //Read from a file, or a HttpRequest, or whatever.
JSONParser jsonParser = new JSONParser();
JSONObject jsonObject = (JSONObject)jsonParser.parse(
      new InputStreamReader(inputStream, "UTF-8"));

h2.myClass is only valid for h2 elements which got the class myClass directly assigned.

Your want to note it like this:

.myClass h2

Which selects all children of myClass which have the tagname h2

yes just do

git checkout master
git pull
git checkout mobiledevicesupport
git merge master

to keep mobiledevicesupport in sync with master

then when you're ready to put mobiledevicesupport into master, first merge in master like above, then ...

git checkout master
git merge mobiledevicesupport
git push origin master

and thats it.

the assumption here is that mobilexxx is a topic branch with work that isn't ready to go into your main branch yet. So only merge into master when mobiledevicesupport is in a good place

In 5.2, you can use the request directly with:

$request->route()->getName();

or via the helper method:

request()->route()->getName();

Output example:

"home.index"

I had the same issue when I was using GIT bash to merge master branch in to my feature branch. I followed the following steps to overcome this.

1. press 'i' (To insert a merge message)
2. write your merge message
3. press esc button (To go back)
4. write ':wq' (write & quit)
5. then press enter

I had exactly the same problem. My environment was:

• Spring STS 3.7.3.RELEASE
• Build Id: 201602250940
• Platform: Eclipse Mars.2 (4.5.2)

The symptoms of the problems were:

1. There was a red error flag on my PM file. and the description of the error was as described in the original question asked here.
2. There were known compilation problems in the several Java files in the project, but eclipse still was not showing them flagged as error in the editor pane as well as the project explorer tree on the left side.

The solution (described above) about updating the m2e extensions worked for me.

Better solution (my recommondation):

• update Eclipse m2e extensions
• From Help > Install New Software.., add a new repository (via the Add.. option), pointing to the following URL: https://otto.takari.io/content/sites/m2e.extras/m2eclipse-mavenarchiver/0.17.2/N/LATEST/
• Select the m2e extensions, accept the license.
• After update, you will be asked for restarting STS. The problem goes away after STS comes back up.

Remember to include System.Diagnostics

ProcessStartInfo startInfo = new ProcessStartInfo("myfile.exe");        // exe file
startInfo.WorkingDirectory = @"C:\..\MyFile\bin\Debug\netcoreapp3.1\"; // exe folder

//here you add your arguments
startInfo.ArgumentList.Add("arg0");       // First argument          
startInfo.ArgumentList.Add("arg2");       // second argument
startInfo.ArgumentList.Add("arg3");       // third argument
Process.Start(startInfo);                 

The default constructor has no arguments. You need to specify a constructor:

    public Friends( String firstName, String age) { ... }

I had faced the same problem but it was on Visual studios's own web development server instead of IIS.The get around is to uncheck the option in Web tab under project properties, Apply server settings to all users(store in project file.).Hope it will save some one's valuable time.

The following permissions and features are necessary in the AndroidManifest.xml file without which you will get the following dialog box

"It seems that your device does not support camera (or it is locked). Application will be closed"

  <uses-permission android:name="android.permission.CAMERA"/>

    <uses-feature android:name="android.hardware.camera" android:required="false"/>
    <uses-feature android:name="android.hardware.camera.autofocus" android:required="false"/>
    <uses-feature android:name="android.hardware.camera.front" android:required="false"/>
    <uses-feature android:name="android.hardware.camera.front.autofocus" android:required="false"/>

I've decided to give an answer to this question because I think it can be solved using a simpler syntax than the convoluted try-catch block. The Laravel documentation is pretty brief on this subject.

Instead of using try-catch, you can just use the DB::transaction(){...} wrapper like this:

// MyController.php
public function store(Request $request) {
    return DB::transaction(function() use ($request) {
        $user = User::create([
            'username' => $request->post('username')
        ]);

        // Add some sort of "log" record for the sake of transaction:
        $log = Log::create([
            'message' => 'User Foobar created'
        ]);

        // Lets add some custom validation that will prohibit the transaction:
        if($user->id > 1) {
            throw AnyException('Please rollback this transaction');
        }

        return response()->json(['message' => 'User saved!']);
    });
};

You should then see that the User and the Log record cannot exist without eachother.

Some notes on the implementation above:

• Make sure to return the transaction, so that you can use the response() you return within its callback.
• Make sure to throw an exception if you want the transaction to be rollbacked (or have a nested function that throws the exception for you automatically, like an SQL exception from within Eloquent).
• The id, updated_at, created_at and any other fields are AVAILABLE AFTER CREATION for the $user object (for the duration of this transaction). The transaction will run through any of the creation logic you have. HOWEVER, the whole record is discarded when the AnyException is thrown. This means that for instance an auto-increment column for id does get incremented on failed transactions.

Tested on Laravel 5.8

the tutorial of how to build NodeJS for Android https://github.com/dna2github/dna2oslab/tree/master/android/build
there are several versions v0.12, v4, v6, v7

It is easy to run compiled binary on Android; for example run compiled Nginx: https://github.com/dna2github/dna2mtgol/tree/master/fileShare

You just need to modify code to replace Nginx to NodeJS; it is better if using Android Service to run node js server on the backend.

The font-min-size and font-max-size CSS properties were removed from the CSS Fonts Module Level 4 specification (and never implemented in browsers AFAIK). And the CSS Working Group replaced the CSS examples with font-size: clamp(...) which doesn't have the greatest browser support yet so we'll have to wait for browsers to support it. See example in https://developer.mozilla.org/en-US/docs/Web/CSS/clamp#Examples.

Most of the answares say that you need to remove the libraries of your solution, this is true but when you re-add the libraries the error will be shown again. You need to verify if all the libraries referenced have a compatible .net framework with the .net framework of your solution. Then fix all the errors in your code and rebuild the solution.

The .Elements operation returns a LIST of XElements - but what you really want is a SINGLE element. Add this:

XElement Contacts = (from xml2 in XMLDoc.Elements("Contacts").Elements("Node")
                    where xml2.Element("ID").Value == variable
                    select xml2).FirstOrDefault();

This way, you tell LINQ to give you the first (or NULL, if none are there) from that LIST of XElements you're selecting.

Try this:

Calendar calendar = Calendar.getInstance();
calendar.setTime(yourdate);
int hours = calendar.get(Calendar.HOUR_OF_DAY);
int minutes = calendar.get(Calendar.MINUTE);
int seconds = calendar.get(Calendar.SECOND);

Edit:

hours, minutes, seconds

above will be the hours, minutes and seconds after converting yourdate to System Timezone!

I had the same problem and i fixed it by checking what version pip (pip3 --version) is, then realizing I'm typing python<uncorrect version> filename.py instead of python<correct version> filename.py

The MDN documentation shows how the getItem method is implementated:

Object.defineProperty(oStorage, "getItem", {
      value: function (sKey) { return sKey ? this[sKey] : null; },
      writable: false,
      configurable: false,
      enumerable: false
    });

If the value isn't set, it returns null. You are testing to see if it is undefined. Check to see if it is null instead.

if(localStorage.getItem("username") === null){

try this

1. cd /var/www/html
2. setenforce 0
3. service httpd restart

What I do in my projects is to activate the following option in the "Constant conditions & exceptions" code inspection:
Suggest @Nullable annotation for methods that may possibly return null and report nullable values passed to non-annotated parameters

When activated, all non-annotated parameters will be treated as non-null and thus you will also see a warning on your indirect call:

clazz.indirectPathToA(null); 

For even stronger checks the Checker Framework may be a good choice (see this nice tutorial.
Note: I have not used that yet and there may be problems with the Jack compiler: see this bugreport

WARNING: setting this value too high may cause your system to experience a significant hiccup. The higher the value you set, the more virtual memory is allocated to the screen process when initiating the screen session. I set my ~/.screenrc to "defscrollback 123456789" and when I initiated a screen, my entire system froze up for a good 10 minutes before coming back to the point that I was able to kill the screen process (which was consuming 16.6GB of VIRT mem by then).

Doing this would require to break the browser sandbox. Try to let your server do the lookup and request that from the client side via XmlHttp.

var myVar = $("#start").find('.myClass').first().val();

GetCursorPos() will return to you the x/y if you pass in a pointer to a POINT structure.

Hiding the cursor can be done with ShowCursor().

The problem comes in by me not knowing how to send a unique identifier with an ng-click to only expand/collapse the right content.

You can pass $event with ng-click (ng-dblclick, and ng- mouse events), then you can determine which element caused the event:

<a ng-click="doSomething($event)">do something</a>

Controller:

$scope.doSomething = function(ev) {
    var element = ev.srcElement ? ev.srcElement : ev.target;
    console.log(element, angular.element(element))
    ...
}

This one is ugly, but just want to throw there some other options to the mix. This one has no loops. I use it for debugging purposes

var myObject = {a:1,b:2,c:3,d:{a:1,b:2,c:3,e:{a:1}}}
var myStrObj = JSON.stringify(myObject)
var myHtmlTableObj = myStrObj.replace(/{/g,"<table><tr><td>").replace(/:/g,"</td><td>","g").replace(/,/g,"</td></tr><tr><td>","g").replace(/}/g,"</table>")

$('#myDiv').html(myHtmlTableObj)

Example:

    var myObject = {a:1,b:2,c:3,d:{a:1,b:2,c:3,e:{a:1}}}_x000D_
    var myStrObj = JSON.stringify(myObject)_x000D_
    var myHtmlTableObj = myStrObj.replace(/\"/g,"").replace(/{/g,"<table><tr><td>").replace(/:/g,"</td><td>","g").replace(/,/g,"</td></tr><tr><td>","g").replace(/}/g,"</table>")_x000D_
_x000D_
    $('#myDiv').html(myHtmlTableObj)

#myDiv table td{background:whitesmoke;border:1px solid lightgray}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
<div id='myDiv'>table goes here</div>

The problem with the answer that was chosen here is that when navigating back and forth, the converter will get triggered every time the page is shown.

This causes new file handles to be created continuously and will block any attempt to delete the file because it is still in use. This can be verified by using Process Explorer.

If the image file might be deleted at some point, a converter such as this might be used: using XAML to bind to a System.Drawing.Image into a System.Windows.Image control

The disadvantage with this memory stream method is that the image(s) get loaded and decoded every time and no caching can take place: "To prevent images from being decoded more than once, assign the Image.Source property from an Uri rather than using memory streams" Source: "Performance tips for Windows Store apps using XAML"

To solve the performance issue, the repository pattern can be used to provide a caching layer. The caching could take place in memory, which may cause memory issues, or as thumbnail files that reside in a temp folder that can be cleared when the app exits.

The preceding 0 is used to indicate a number in base 2, 8, or 16.

In my opinion, 0x was chosen to indicate hex because 'x' sounds like hex.

Just my opinion, but I think it makes sense.

Good Day!

For completeness, echo $(__git_ps1), on Linux at least, should give you the name of the current branch surrounded by parentheses.

This may be useful is some scenarios as it is not a Git command (while depending on Git), notably for setting up your Bash command prompt to display the current branch.

For example:

/mnt/c/git/ConsoleApp1 (test-branch)> echo $(__git_ps1)
(test-branch)
/mnt/c/git/ConsoleApp1 (test-branch)> git checkout master
Switched to branch 'master'
/mnt/c/git/ConsoleApp1 (master)> echo $(__git_ps1)
(master)
/mnt/c/git/ConsoleApp1 (master)> cd ..
/mnt/c/git> echo $(__git_ps1)

/mnt/c/git>

I faced the same issue. I had missed the forms module import tag in the app.module.ts

import { FormsModule } from '@angular/forms';

@NgModule({
    imports: [BrowserModule,
        FormsModule
    ],

WINDOWS + WAMP solution

Step 1
Go to C:\wamp\bin\apache\Apache2.2.17\conf\
open httpd.conf file and change
#Include conf/extra/httpd-vhosts.conf
to
Include conf/extra/httpd-vhosts.conf
i.e. uncomment the line so that it can includes the virtual hosts file.

Step 2
Go to C:\wamp\bin\apache\Apache2.2.17\conf\extra
and open httpd-vhosts.conf file and add the following code

<VirtualHost myWebsite.local>
    DocumentRoot "C:/wamp/www/myWebsite/"
    ServerName myWebsite.local
    ServerAlias myWebsite.local
    <Directory "C:/wamp/www/myWebsite/">
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

change myWebsite.local and C:/wamp/www/myWebsite/ as per your requirements.

Step 3
Open hosts file in C:/Windows/System32/drivers/etc/ and add the following line ( Don't delete anything )

127.0.0.1 myWebsite.local

change myWebsite.local as per your name requirements

Step 4
restart your server. That's it

WINDOWS + XAMPP solution

Same steps as that of WAMP just change the paths according to XAMPP which corresponds to path in WAMP

Under Python 3.x, you can do this nicely:

>>> head, *tail = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55]
>>> head
1
>>> tail
[1, 2, 3, 5, 8, 13, 21, 34, 55]

A new feature in 3.x is to use the * operator in unpacking, to mean any extra values. It is described in PEP 3132 - Extended Iterable Unpacking. This also has the advantage of working on any iterable, not just sequences.

It's also really readable.

As described in the PEP, if you want to do the equivalent under 2.x (without potentially making a temporary list), you have to do this:

it = iter(iterable)
head, tail = next(it), list(it)

As noted in the comments, this also provides an opportunity to get a default value for head rather than throwing an exception. If you want this behaviour, next() takes an optional second argument with a default value, so next(it, None) would give you None if there was no head element.

Naturally, if you are working on a list, the easiest way without the 3.x syntax is:

head, tail = seq[0], seq[1:]

I'm not sure exactly what you want, but it sounds like it should be possible, and it also sounds like you're already on the right track.

Here are a few links that might help:

Disable back button in android

  MyActivity.java =>
    @Override
    public void onBackPressed() {

       return;
    }

How can I disable 'go back' to some activity?

  AndroidManifest.xml =>
<activity android:name=".SplashActivity" android:noHistory="true"/>

You can create the required headers in a filter too.

@WebFilter(urlPatterns="/rest/*")
public class AllowAccessFilter implements Filter {
    @Override
    public void doFilter(ServletRequest sRequest, ServletResponse sResponse, FilterChain chain) throws IOException, ServletException {
        System.out.println("in AllowAccessFilter.doFilter");
        HttpServletRequest request = (HttpServletRequest)sRequest;
        HttpServletResponse response = (HttpServletResponse)sResponse;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "GET, POST, PUT");
        response.setHeader("Access-Control-Allow-Headers", "Content-Type"); 
        chain.doFilter(request, response);
    }
    ...
}

Put

android:duplicateParentState="true"

in child then the views get its drawable state (focused, pressed, etc.) from its direct parent rather than from itself. you can set onclick for parent and it call on child clicked

Try something like this: Create the final object table, tmpFerdeen with the structure of the union.

Then

INSERT INTO tmpFerdeen (
SELECT top(100)* 
FROM Customers
UNION All
SELECT top(100)* 
FROM CustomerEurope
UNION All
SELECT top(100)* 
FROM CustomerAsia
UNION All
SELECT top(100)* 
FROM CustomerAmericas
)

With numpy :

im = Image.open('image.gif')
im_matrix = np.array(im)
print(im_matrix[0][0])

Give RGB vector of the pixel in position (0,0)

The IN was too slow in my situation (180 secs)

So I used a JOIN instead (0.3 secs)

SELECT i.id, i.payer_email
FROM paypal_ipn_orders i
INNER JOIN (
 SELECT payer_email
    FROM paypal_ipn_orders 
    GROUP BY payer_email
    HAVING COUNT( id ) > 1
) j ON i.payer_email=j.payer_email

for all xml with namespace use local-name()

//*[local-name()='Parent'][@id='1']/*[local-name()='Children']/*[local-name()='child']/@name 

The order of execution of ng-click and ng-model is different with angular 1.2 vs 1.6

You must test, with 1.2 and 1.6,

for example, with angular 1.2, ng-click get execute before ng-model, with angular 1.6, ng-model maybe get excute before ng-click.

so you get 'true checked' / 'false uncheck' value maybe not you expect

while(inFile1.hasNext()){

    token1 = inFile1.nextLine();

    // put each value into an array with String#split();
    String[] numStrings = line.split(", ");

    // parse number string into doubles 
    double[] nums = new double[numString.length];

    for (int i = 0; i < nums.length; i++){
        nums[i] = Double.parseDouble(numStrings[i]);
    }

}

If it's a global variable then window[variableName] or in your case window["onlyVideo"] should do the trick.

You could consider only appending internal to your url if it is true, then if the checkbox isn't checked and you don't append it params[:internal] would be nil, which evaluates to false in Ruby.

I'm not that familiar with the specific jQuery you're using, but is there a cleaner way to call what you want than manually building a URL string? Have you had a look at $get and $ajax?

The _ is the same thing as x. However it's a python idiom that's used to indicate an identifier that you don't intend to use. In python these identifiers don't takes memor or allocate space like variables do in other languages. It's easy to forget that. They're just names that point to objects, in this case an integer on each iteration.

This can be done with tables:

<table cellpadding="0" cellspacing="0" width="100%" height="100%">
    <tr height="0%"><td>
        <div id="full">
            <!--contents of 1 -->
        </div>
    </td></tr>
    <tr><td>
        <div id="someid">
            <!--contents of 2 -->
        </div>
    </td></tr>
</table>

Then apply css to make someid fill the remaining space:

#someid {
    height: 100%;
}

Now, I can just hear the angry shouts from the crowd, "Oh noes, he's using tables! Feed him to the lions!" Please hear me out.

Unlike the accepted answer which accomplishes nothing aside from making the container div the full height of the page, this solution makes div #2 fill the remaining space as requested in the question. If you need that second div to fill the full height allotted to it, this is currently the only way to do it.

But feel free to prove me wrong, of course! CSS is always better.

select ADU.itemid, ADU.startdate, internalcostprice 
from ADUITEMINTERNALCOSTPRICE ADU

right join

   (select max(STARTDATE) as Max_date, itemid 
   from ADUITEMINTERNALCOSTPRICE
   group by itemid) as A

on A.ITEMID = ADU.ITEMID
and startdate= Max_date

a div usually needs at least a non-breaking space (&nbsp;) in order to have a width.

You can use np.logaddexp (which implements the idea in @gg349's answer):

In [33]: d = np.array([[1089, 1093]])

In [34]: e = np.array([[1000, 4443]])

In [35]: log_res = np.logaddexp(-3*d[0,0], -3*d[0,1]) - np.logaddexp(-3*e[0,0], -3*e[0,1])

In [36]: log_res
Out[36]: -266.99999385580668

In [37]: res = exp(log_res)

In [38]: res
Out[38]: 1.1050349147204485e-116

Or you can use scipy.special.logsumexp:

In [52]: from scipy.special import logsumexp

In [53]: res = np.exp(logsumexp(-3*d) - logsumexp(-3*e))

In [54]: res
Out[54]: 1.1050349147204485e-116

For checking type conversions in version 3, you can go to their github and check into the different liquibase types and check the method toDatabaseDataType. For example, for Boolean, you can check here:

https://github.com/liquibase/liquibase/blob/master/liquibase-core/src/main/java/liquibase/datatype/core/BooleanType.java

For version 2.0.x, the conversion seems to be into database specific classes. For example, for Mysql:

https://github.com/liquibase/liquibase/blob/2_0_x/liquibase-core/src/main/java/liquibase/database/typeconversion/core/MySQLTypeConverter.java

I always use the x:Name variant. I have no idea if this affects any performance, I just find it easier for the following reason. If you have your own usercontrols that reside in another assembly just the "Name" property won't always suffice. This makes it easier to just stick too the x:Name property.

To give gradient color to UIView (swift 4.2)

func makeGradientLayer(`for` object : UIView, startPoint : CGPoint, endPoint : CGPoint, gradientColors : [Any]) -> CAGradientLayer {
        let gradient: CAGradientLayer = CAGradientLayer()
        gradient.colors = gradientColors
        gradient.locations = [0.0 , 1.0]
        gradient.startPoint = startPoint
        gradient.endPoint = endPoint
        gradient.frame = CGRect(x: 0, y: 0, w: object.frame.size.width, h: object.frame.size.height)
        return gradient
    }

How to use

let start : CGPoint = CGPoint(x: 0.0, y: 1.0)
let end : CGPoint = CGPoint(x: 1.0, y: 1.0)

let gradient: CAGradientLayer = makeGradientLayer(for: cell, startPoint: start, endPoint: end, gradientColors: [
                    UIColor(red:0.92, green:0.07, blue:0.4, alpha:1).cgColor,
                    UIColor(red:0.93, green:0.11, blue:0.14, alpha:1).cgColor
                    ])

self.vwTemp.layer.insertSublayer(gradient, at: 0)

I also had problem with this error, and came upon a solution. This does not explain why the error occurred, but it seems to fix it in some cases.

Include a forward slash / before the path to the css file, like so:

<link rel="stylesheet" href="/css/bootstrap.min.css">

Another fairly simple way to go about this is to make a method like this:

def _write_frame_to_new_sheet(path_to_file=None, sheet_name='sheet', data_frame=None):
    book = None
    try:
        book = load_workbook(path_to_file)
    except Exception:
        logging.debug('Creating new workbook at %s', path_to_file)
    with pd.ExcelWriter(path_to_file, engine='openpyxl') as writer:
        if book is not None:
            writer.book = book
        data_frame.to_excel(writer, sheet_name, index=False)

The idea here is to load the workbook at path_to_file if it exists and then append the data_frame as a new sheet with sheet_name. If the workbook does not exist, it is created. It seems that neither openpyxl or xlsxwriter append, so as in the example by @Stefano above, you really have to load and then rewrite to append.

Update to this for using Hibernate 4.3.x / 5.0.x - you could just set this property to true:

Change branch, discarding all local modifications

git checkout -f 9-sign-in-out 

Rename the current branch to master, discarding current master

git branch -M master 

The essence is this:

1. You're calling 'append' on the parent
2. but you want to call 'show' on the new child

This works for me:

var new_item = $('<p>hello</p>').hide();
parent.append(new_item);
new_item.show('normal');

or:

$('<p>hello</p>').hide().appendTo(parent).show('normal');

I don't think there's anything wrong with either solutions you proposed in your question.

In my own code, I would implement it like this though:

(x for x in seq if predicate(x)).next()

The syntax with () creates a generator, which is more efficient than generating all the list at once with [].

Array.indexOf doesnt work in some versions of internet explorer - there are lots of alternative ways of doing it though ... see this question / answer : How do I check if an array includes an object in JavaScript?

Create base class for all controllers and put here name attribute:

public abstract class MyBaseController : Controller
{
    public abstract string Name { get; }
}

In view

@{
    var controller = ViewContext.Controller as MyBaseController;
    if (controller != null)
    {
       @controller.Name
    }
}

Controller example

 public class SampleController: MyBaseController 
    { 
      public override string Name { get { return "Sample"; } 
    }

I just went through the learning process myself. I figured it out, but I agree the documentation is written in a way that was sorta intimidating to me. The big "aha" moment for me was understanding that for browsing, all CKeditor does is open a new window and provide a few parameters in the url. It allows you to add additional parameters but be advised you will need to use encodeURIComponent() on your values.

I call the browser and the uploader with

CKEDITOR.replace( 'body',  
{  
    filebrowserBrowseUrl: 'browse.php?type=Images&dir=' +  
        encodeURIComponent('content/images'),  
    filebrowserUploadUrl: 'upload.php?type=Files&dir=' +  
        encodeURIComponent('content/images')  
}

For the browser, in the open window (browse.php) you use php & js to supply a list of choices and then upon your supplied onclick handler, you call a CKeditor function with two arguments, the url/path to the selected image and CKEditorFuncNum supplied by CKeditor in the url:

function myOnclickHandler(){  
//..    
    window.opener.CKEDITOR.tools.callFunction(<?php echo $_GET['CKEditorFuncNum']; ?>, pathToImage);  
    window.close();
}       

Simarly, the uploader simply calls the url you supply, e.g., upload.php, and again supplies $_GET['CKEditorFuncNum']. The target is an iframe so, after you save the file from $_FILES you pass your feedback to CKeditor as thus:

$funcNum = $_GET['CKEditorFuncNum'];  
exit("<script>window.parent.CKEDITOR.tools.callFunction($funcNum, '$filePath', '$errorMessage');</script>");  

Below is a simple to understand custom browser script. While it does not allow users to navigate around in the server, it does allow you to indicate which directory to pull image files from when calling the browser.

It's all rather basic coding so it should work in all relatively modern browsers.

CKeditor merely opens a new window with the url provided

/*          
    in CKeditor **use encodeURIComponent()** to add dir param to the filebrowserBrowseUrl property

    Replace content/images with directory where your images are housed.
*/          
        CKEDITOR.replace( 'editor1', {  
            filebrowserBrowseUrl: '**browse.php**?type=Images&dir=' + encodeURIComponent('content/images'),  
            filebrowserUploadUrl: 'upload.php?type=Files&dir=' + encodeURIComponent('content/images') 
        });

Name2 is a field. WPF binds only to properties. Change it to:

public string Name2 { get; set; }

Be warned that with this minimal implementation, your TextBox won't respond to programmatic changes to Name2. So for your timer update scenario, you'll need to implement INotifyPropertyChanged:

partial class Window1 : Window, INotifyPropertyChanged
{
  public event PropertyChangedEventHandler PropertyChanged;

  protected void OnPropertyChanged(string propertyName)
  {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
  }

  private string _name2;

  public string Name2
  {
    get { return _name2; }
    set
    {
      if (value != _name2)
      {
         _name2 = value;
         OnPropertyChanged("Name2");
      }
    }
  }
}

You should consider moving this to a separate data object rather than on your Window class.

I was dealing with this issue today, and I knew that I had something encoded as a bytes object that I was trying to serialize as json with json.dump(my_json_object, write_to_file.json). my_json_object in this case was a very large json object that I had created, so I had several dicts, lists, and strings to look at to find what was still in bytes format.

The way I ended up solving it: the write_to_file.json will have everything up to the bytes object that is causing the issue.

In my particular case this was a line obtained through

for line in text:
    json_object['line'] = line.strip()

I solved by first finding this error with the help of the write_to_file.json, then by correcting it to:

for line in text:
    json_object['line'] = line.strip().decode()

According to the Java Language Specification (specifically §10.7 Array Members) it is a field:

• The public final field length, which contains the number of components of the array (length may be positive or zero).

Internally the value is probably stored somewhere in the object header, but that is an implementation detail and depends on the concrete JVM implementation.

The HotSpot VM (the one in the popular Oracle (formerly Sun) JRE/JDK) stores the size in the object-header:

[...] arrays have a third header field, for the array size.

List<String> lsColumns = new List<string>();

if(dt.Rows.Count>0)
{
    var count = dt.Rows[0].Table.Columns.Count;

    for (int i = 0; i < count;i++ )
    {
        lsColumns.Add(Convert.ToString(dt.Rows[0][i]));
    }
}

As trivial as it may be, I had to restart Windows when faced with this problem.

I am running Windows 7 x64. I did a manual update to the system PATH variable. This worked okay if I ran cmd.exe from the stat menu. But if I type "cmd" in the Windows Explorer address bar, it seems to load the PATH from elsewhere, which doesn't have my manual changes.

(To avoid doubt - yes, I did close and rerun cmd a couple of times before I restarted and it didn't help.)

$('#search').autocomplete( { source: items } );
$('#search:focus').autocomplete('search', $('#search').val() );

This seems to be the only one that worked for me.

I just use the UTF code for space "\u0020" in the strings.xml file.

<string name="some_string">\u0020The name of my string.\u0020\u0020</string>

works great. (Android loves UTF codes)

No Jquery Solution - Basic

The most basic draggable code would be :

Element.prototype.drag = function(){

   var mousemove = function(e){ // document mousemove

       this.style.left = ( e.clientX - this.dragStartX ) + 'px';
       this.style.top  = ( e.clientY - this.dragStartY ) + 'px';

   }.bind(this);

   var mouseup = function(e){ // document mouseup

       document.removeEventListener('mousemove',mousemove);
       document.removeEventListener('mouseup',mouseup);

   }.bind(this);

   this.addEventListener('mousedown',function(e){ // element mousedown

       this.dragStartX = e.offsetX;
       this.dragStartY = e.offsetY;

       document.addEventListener('mousemove',mousemove);
       document.addEventListener('mouseup',mouseup);

   }.bind(this));

   this.style.position = 'absolute' // fixed might work as well

}

and then usage (non-jquery) :

document.querySelector('.target').drag();

or in jquery :

$('.target')[0].drag();

Notice : the dragged element should have a position:absolute or position:fixed applied to it for the left,top movement to work...

the codepen below has some more "advanced" features : dragStart, dragStop callbacks, css classes appending to remove text selection of other elements while dragging, and a drop feature also...

checkout the following codepen :

http://codepen.io/anon/pen/VPPaEK

its basically setting a 'mousedown' event on the element which needs to be dragged, and then binding and unbinding the document mousemove to handle the movement.

Draggable Handle

in order to set a draggable handle for the element

Element.prototype.drag = function( setup ){

   var setup = setup || {};

   var mousemove = function(e){ // document mousemove

       this.style.left = ( e.clientX - this.dragStartX ) + 'px';
       this.style.top  = ( e.clientY - this.dragStartY ) + 'px';

   }.bind(this);

   var mouseup = function(e){ // document mouseup

       document.removeEventListener('mousemove',mousemove);
       document.removeEventListener('mouseup',mouseup);

   }.bind(this);

   var handle = setup.handle || this;

   handle.addEventListener('mousedown',function(e){ // element mousedown

       this.dragStartX = e.offsetX;
       this.dragStartY = e.offsetY;

       document.addEventListener('mousemove',mousemove);
       document.addEventListener('mouseup',mouseup);

       handle.classList.add('dragging');

   }.bind(this)); 

   handle.classList.add('draggable');

   this.style.position = 'absolute' // fixed might work as well

}

The above code is used like so :

var setup = {
   handle : document.querySelector('.handle')
};

document.querySelector('.box').drag(setup);

Adding CSS to eliminate selectable text

The problem now, is that when dragging, the text within the draggable element is annoyingly being selected with no use...

This is why we have added the draggable and dragging classes to the element. which will cancel out this unwanted behavior, and also add a move cursor, to display that this element is draggable

.draggable{
    cursor: move;
    position: fixed;
}

.draggable.dragging{
    user-select: none;
}

Adding Events

So now that we have our draggable element, we sometimes need to call various events.

setup.ondraginit  // this is called when setting up the draggable
setup.ondragstart // this is called when mouse is down on the element
setup.ondragend   // this is called when mouse is released (after dragging)
setup.ondrag      // this is called while the element is being dragged

Each will pass the original mouse event to the specific handler

Finally, this is what we get...

Element.prototype.drag = function( setup ){

    var setup = setup || {};

    var mousemove = function(e){ // document mousemove

        this.style.left = ( e.clientX - this.dragStartX ) + 'px';
        this.style.top  = ( e.clientY - this.dragStartY ) + 'px';

        setup.ondrag && setup.ondrag(e); // ondrag event

    }.bind(this);

    var mouseup = function(e){ // document mouseup

        document.removeEventListener('mousemove',mousemove);
        document.removeEventListener('mouseup',mouseup);

        handle.classList.remove('dragging');

        setup.ondragend && setup.ondragend(e); // ondragend event

    }.bind(this);

    var handle = setup.handle || this;

    handle.addEventListener('mousedown',function(e){ // element mousedown

        this.dragStartX = e.offsetX;
        this.dragStartY = e.offsetY;

        document.addEventListener('mousemove',mousemove);
        document.addEventListener('mouseup',mouseup);

        handle.classList.add('dragging');

        setup.ondragstart && setup.ondragstart(e); // ondragstart event

    }.bind(this)); 

    handle.classList.add('draggable');

    setup.ondraginit && setup.ondraginit(e); // ondraginit event

}

And to use this :

var setup = {
   handle      : document.querySelector('.handle'),
   ondragstart : e => { console.log('drag has started!'); },
   ondrag      : e => { console.log('drag!'); },
   ondragend   : e => { console.log('drag has ended!'); }
};

document.querySelector('.box').drag(setup);

note that e.target is a reference back to our draggable element

Share Files, Folders or Drives Between Host and Hyper-V Virtual Machine

Prerequisites

1. Ensure that Enhanced session mode settings are enabled on the Hyper-V host.

   Start Hyper-V Manager, and in the Actions section, select "Hyper-V Settings".

   

   Make sure that enhanced session mode is allowed in the Server section. Then, make sure that the enhanced session mode is available in the User section.

   

2. Enable Hyper-V Guest Services for your virtual machine

   Right-click on Virtual Machine > Settings. Select the Integration Services in the left-lower corner of the menu. Check Guest Service and click OK.

   

Steps to share devices with Hyper-v virtual machine:

1. Start a virtual machine and click Show Options in the pop-up windows.

   

   Or click "Edit Session Settings..." in the Actions panel on the right

   

   It may only appear when you're (able to get) connected to it. If it doesn't appear try Starting and then Connecting to the VM while paying close attention to the panel in the Hyper-V Manager.

2. View local resources. Then, select the "More..." menu.

   

3. From there, you can choose which devices to share. Removable drives are especially useful for file sharing.

   

4. Choose to "Save my settings for future connections to this virtual machine".

   

5. Click Connect. Drive sharing is now complete, and you will see the shared drive in this PC > Network Locations section of Windows Explorer after using the enhanced session mode to sigh to the VM. You should now be able to copy files from a physical machine and paste them into a virtual machine, and vice versa.

The first bin in the FFT is DC (0 Hz), the second bin is Fs / N, where Fs is the sample rate and N is the size of the FFT. The next bin is 2 * Fs / N. To express this in general terms, the nth bin is n * Fs / N.

So if your sample rate, Fs is say 44.1 kHz and your FFT size, N is 1024, then the FFT output bins are at:

  0:   0 * 44100 / 1024 =     0.0 Hz
  1:   1 * 44100 / 1024 =    43.1 Hz
  2:   2 * 44100 / 1024 =    86.1 Hz
  3:   3 * 44100 / 1024 =   129.2 Hz
  4: ...
  5: ...
     ...
511: 511 * 44100 / 1024 = 22006.9 Hz

Note that for a real input signal (imaginary parts all zero) the second half of the FFT (bins from N / 2 + 1 to N - 1) contain no useful additional information (they have complex conjugate symmetry with the first N / 2 - 1 bins). The last useful bin (for practical aplications) is at N / 2 - 1, which corresponds to 22006.9 Hz in the above example. The bin at N / 2 represents energy at the Nyquist frequency, i.e. Fs / 2 ( = 22050 Hz in this example), but this is in general not of any practical use, since anti-aliasing filters will typically attenuate any signals at and above Fs / 2.

You're accessing the latitude and longitude incorrectly.

Try

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">

var geocoder = new google.maps.Geocoder();
var address = "new york";

geocoder.geocode( { 'address': address}, function(results, status) {

  if (status == google.maps.GeocoderStatus.OK) {
    var latitude = results[0].geometry.location.lat();
    var longitude = results[0].geometry.location.lng();
    alert(latitude);
  } 
}); 
</script>

Use can use plain JavaScript's Array#filter method like this:

var arr = [{id:1,name:'a'},{id:2,name:'b'},{id:3,name:'c'}];_x000D_
_x000D_
var filteredArr = arr.filter(obj => obj.id != 3);_x000D_
_x000D_
console.log(filteredArr);

Or, use Array#reduce and Array#concat methods like this:

var arr = [{id:1,name:'a'},{id:2,name:'b'},{id:3,name:'c'}];_x000D_
_x000D_
var reducedArr = arr.reduce((accumulator, currObj) => {_x000D_
  return (currObj.id != 3) ? accumulator.concat(currObj) : accumulator;_x000D_
}, []);_x000D_
_x000D_
console.log(reducedArr);

NOTE:

• Both of these are pure functional approach (i.e. they don't modify the existing array).
• No, external library is required in these approach (Vanilla JavaScript is enough).

I solve this by simply add 'https:' to slick cdn link gotfrom slick

Downgrading the JRE from 7 to 6 fixed this issue for me.

This works in Mac as well you can use

df= pd.read_csv('Region_count.csv', encoding ='latin1')

You can put df_try inside a list and then do what you have in mind:

>>> df.append([df_try]*5,ignore_index=True)

    Store  Dept       Date  Weekly_Sales IsHoliday

13      1     1 2010-02-12      46039.49      True

its better to use the Dependency than to attache it to the class.

public function add_question(Request $request)
{
    return Request::all();
}

or if you prefer using input variable use

public function add_question(Request $input)
{
    return $input::all();
}

you can now use the global request method provided by laravel

request()

for example to get the first_name of a form input.

request()->first_name
// or
request('first_name')

I prefer to use an angular filter.

app.filter('num', function() {
    return function(input) {
      return parseInt(input, 10);
    };
});

then you can use this in the dom:

{{'10'|num}}

Here is a fiddle.

Hope this helped!

You have to first obtain the Range object. Also, getCell() will not return the value of the cell but instead will return a Range object of the cell. So, use something on the lines of

function email() {

// Opens SS by its ID

var ss = SpreadsheetApp.openById("0AgJjDgtUl5KddE5rR01NSFcxYTRnUHBCQ0stTXNMenc");

// Get the name of this SS

var name = ss.getName();  // Not necessary 

// Read cell 1,1 * Line below does't work *

// var data = Range.getCell(0, 0);
var sheet = ss.getSheetByName('Sheet1'); // or whatever is the name of the sheet 
var range = sheet.getRange(1,1); 
var data = range.getValue();

}

The hierarchy is Spreadsheet --> Sheet --> Range --> Cell.

In the answers above, the super is initialized without any (keyword) arguments. Often, however, you would like to do that, as well as pass on some 'custom' arguments of your own. Here is an example which illustrates this use case:

class SortedList(list):
    def __init__(self, *args, reverse=False, **kwargs):
        super().__init__(*args, **kwargs)       # Initialize the super class
        self.reverse = reverse
        self.sort(reverse=self.reverse)         # Do additional things with the custom keyword arguments

This is a subclass of list which, when initialized, immediately sorts itself in the direction specified by the reverse keyword argument, as the following tests illustrate:

import pytest

def test_1():
    assert SortedList([5, 2, 3]) == [2, 3, 5]

def test_2():
    SortedList([5, 2, 3], reverse=True) == [5, 3, 2]

def test_3():
    with pytest.raises(TypeError):
        sorted_list = SortedList([5, 2, 3], True)   # This doesn't work because 'reverse' must be passed as a keyword argument

if __name__ == "__main__":
    pytest.main([__file__])

Thanks to the passing on of *args to super, the list can be initialized and populated with items instead of only being empty. (Note that reverse is a keyword-only argument in accordance with PEP 3102).

try this:

    $('#autocomplete').focus(function(){
        $(this).val('');
        $(this).keydown();
    }); 

and minLength set to 0

works every time :)

In Java, integer literals are of type int by default. For some other types, you may suffix the literal with a case-insensitive letter like L, D, F to specify a long, double, or float, respectively. Note it is common practice to use uppercase letters for better readability.

The Java Language Specification does not provide the same syntactic sugar for byte or short types. Instead, you may declare it as such using explicit casting:

byte foo = (byte)0;
short bar = (short)0;

In your setLongValue(100L) method call, you don't have to necessarily include the L suffix because in this case the int literal is automatically widened to a long. This is called widening primitive conversion in the Java Language Specification.

You can exchange this local variable for a global, it would be easier.

DROP PROCEDURE IF EXISTS ABC;
DELIMITER $$  
CREATE PROCEDURE ABC()

   BEGIN
      SET @a = 0;
      simple_loop: LOOP
         SET @a=@a+1;
         select @a;
         IF @a=5 THEN
            LEAVE simple_loop;
         END IF;
   END LOOP simple_loop;
END $$

Have you tried adding a configsection handler to your app.config? e.g.

<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>

Swift 5.2:

String(describing: type(of: self))

this is not your answer but is for those come here searching solution for another problem. I wanted to get sum of a column of related table conditionally. In my database Deals has many Activities I wanted to get the sum of the "amount_total" from Activities table where activities.deal_id = deal.id and activities.status = paid so i did this.

$query->withCount([
'activity AS paid_sum' => function ($query) {
            $query->select(DB::raw("SUM(amount_total) as paidsum"))->where('status', 'paid');
        }
    ]);

it returns

"paid_sum_count" => "320.00"

in Deals attribute.

This it now the sum which i wanted to get not the count.

Save the username and password hashes in array in a php file instead of db.

When you need to authenticate the user, compute hashes of his credentials and then compare them to hashes in array.

If you use safe hash function (see hash function and hash algos in PHP documentation), it should be pretty safe (you may consider using salted hash) and also add some protections to the form itself.

You're missing quotes around your string:

...
var htmlString="<?php echo $htmlString; ?>";
...

It is happening Due to:

<p><script>var _nwls=[];if(window.jQuery&&window.jQuery.find){_nwls=jQuery.find(".fw_link_newWindow");}else{if(document.getElementsByClassName){_nwls=document.getElementsByClassName("fw_link_newWindow");}else{if(document.querySelectorAll){_nwls=document.querySelectorAll(".fw_link_newWindow");}else{document.write('<scr'+'ipt src="http://static.websimages.com/static/global/js/sizzle/sizzle.min.js"><\/scr'+'ipt>');if(window.Sizzle){_nwls=Sizzle(".fw_link_newWindow");}}}}var numlinks=_nwls.length;for(var i=0;i<numlinks;i++){_nwls[i].target="_blank";}</script></p>

Remove <p></p> around the script.
