SevenZipSharp is another solution. Creates 7-zip archives...

In R, you can try out this way:

X = NULL
X
# NULL
values = letters[1:10]
values
# [1] "a" "b" "c" "d" "e" "f" "g" "h" "i" "j"
X = append(X,values)
X
# [1] "a" "b" "c" "d" "e" "f" "g" "h" "i" "j"
X = append(X,letters[23:26])
X
# [1] "a" "b" "c" "d" "e" "f" "g" "h" "i" "j" "w" "x" "y" "z"

If your list of words is of substantial length, and you need to do this test many times, it may be worth converting the list to a set and using set intersection to test (with the added benefit that you wil get the actual words that are in both lists):

>>> long_word_list = 'some one long two phrase three about above along after against'
>>> long_word_set = set(long_word_list.split())
>>> set('word along river'.split()) & long_word_set
set(['along'])

You can't use WebSockets over HTTPS, but you can use WebSockets over TLS (HTTPS is HTTP over TLS). Just use "wss://" in the URI.

I believe recent version of Firefox won't let you use non-TLS WebSockets from an HTTPS page, but the reverse shouldn't be a problem.

In my case Codec ID of mp4 file was the issue, Codec ID: isom (isom/iso2/avc1/mp41) was not playing in IE 10 and 11 using video tag, after I converted it to "mp42 (mp42/isom/avc1)" using FFmpeg it started playing in IE as well.

I need to go next only to input and select, and element have to be focusable. This script works better for me:

$('body').on('keydown', 'input, select', function(e) {
    if (e.key === "Enter") {
        var self = $(this), form = self.parents('form:eq(0)'), focusable, next;
        focusable = form.find('input,select,textarea').filter(':visible');
        next = focusable.eq(focusable.index(this)+1);
        if (next.length) {
            next.focus();
        } else {
            form.submit();
        }
        return false;
    }
});

Maybe it helps someone.

Did you change conf/hdfs-site.xml dfs.name.dir?

Format namenode after you change it.

$ bin/hadoop namenode -format
$ bin/hadoop start-all.sh

Easy Workaround (no VBA required)

1. Right Click Table, expand "Table" context manu, select "External Data Properties"
2. Click button "Connection Properties" (labelled in tooltip only)
3. Go-to Tab "Definition"

From here, edit the SQL directly by adding '?' wherever you want a parameter. Works the same way as before except you don't get nagged.

There are many way you can do this. Based on your requirement choose anything from below.

1. By REVERTing commit:

If you want to REVERT all the changes from you last COMMIT that means If you ADD something in your file that will be REMOVED after revert has been done. If you REMOVE something in your file the revert process will ADD those file.

You can REVERT the very last COMMIT. Like:

1.git revert head^
2.git push origin <Branch-Name>

Or you can revert to any previous commit using the hash of that commit.Like:

1.git revert <SHA>
2.git push origin  <Branch-Name>

2. By RESETing previous Head

If you want to just point to any previous commit use reset; it points your local environment back to a previous commit. You can reset your head to previous commit or reset your head to previous any commit.

Reset to previous commit.

1.git reset head^
2.git push -f origin <Branch-name>

Reset to any previous commit:

1.git reset <SHA>
2.git push -f origin <Branch-name>

Trade of between REVERT & RESET:

Why would you choose to do a revert over a reset operation? If you have already pushed your chain of commits to the remote repository (where others may have pulled your code and started working with it), a revert is a nicer way to cancel out changes for them. This is because the Git workflow works well for picking up additional commits at the end of a branch, but it can be challenging if a set of commits is no longer seen in the chain when someone resets the branch pointer back.

For jquery 1.6+, use .prop() instead of .attr(),

$("#parent-selector :input").prop("disabled", true);

or

$("#parent-selector :input").attr("disabled", "disabled");

All procedure at once. Based on @Till Schäfer answer.

FURTHER QUESTION: Wrong information?

If you check memory usage with the ps command, you will see that the java process consumes much more...

ps -eo size,pid,user,command --sort -size | egrep -i "*/bin/java *" | egrep -v grep | awk '{ hr=$1/1024 ; printf("%.2f MB ",hr) } { for ( x=4 ; x<=NF ; x++ ) { printf("%s ",$x) } print "" }' | cut -d "" -f2 | cut -d "-" -f1

UPDATE (2021-02-16):

According to the reference below (and @Till Schäfer comment) "ps can show total reserved memory from OS" (adapted) and "jstat can show used space of heap and stack" (adapted). So, we see a difference between what is pointed out by the ps command and the jstat command.

According to our understanding, the most "realistic" information would be the ps output since we will have an effective response of how much of the system's memory is compromised. The command jstat serves for a more detailed analysis regarding the java performance in the consumption of reserved memory from OS.

Try Shift + Delete. Did 24.000 files in 2 minutes for me.

tl;dr

java.time.temporal.ChronoUnit.DAYS.between( 
    earlier.toLocalDate(), 
    later.toLocalDate() 
)

…or…

java.time.temporal.ChronoUnit.HOURS.between( 
    earlier.truncatedTo( ChronoUnit.HOURS )  , 
    later.truncatedTo( ChronoUnit.HOURS ) 
)

java.time

FYI, the Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes.

The equivalent of Joda-Time DateTime is ZonedDateTime.

ZoneId z = ZoneId.of( "Pacific/Auckland" ) ;
ZonedDateTime now = ZonedDateTime.now( z ) ;

Apparently you want to count the days by dates, meaning you want to ignore the time of day. For example, starting a minute before midnight and ending a minute after midnight should result in a single day. For this behavior, extract a LocalDate from your ZonedDateTime. The LocalDate class represents a date-only value without time-of-day and without time zone.

LocalDate localDateStart = zdtStart.toLocalDate() ;
LocalDate localDateStop = zdtStop.toLocalDate() ;

Use the ChronoUnit enum to calculate elapsed days or other units.

long days = ChronoUnit.DAYS.between( localDateStart , localDateStop ) ;

Truncate

As for you asking about a more general way to do this counting where you are interested the delta of hours as hour-of-the-clock rather than complete hours as spans-of-time of sixty minutes, use the truncatedTo method.

Here is your example of 14:45 to 15:12 on same day.

ZoneId z = ZoneId.of( "America/Montreal" ); 
ZonedDateTime start = ZonedDateTime.of( 2017 , 1 , 17 , 14 , 45 , 0 , 0 , z );
ZonedDateTime stop = ZonedDateTime.of( 2017 , 1 , 17 , 15 , 12 , 0 , 0 , z );

long hours = ChronoUnit.HOURS.between( start.truncatedTo( ChronoUnit.HOURS ) , stop.truncatedTo( ChronoUnit.HOURS ) );

1

This does not work for days. Use toLocalDate() in this case.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

This windows batch works regardless of whether or not it's on GitHub. I'm using it because it shows some stark caveats. You'll notice that the operation is slow and traversing hundreds of megabytes of data, so don't use this method if your requirements are based on available bandwidth/R-W memory.

You can use the following command:
:%s/^V^M//g
where the '^' means use CTRL key.

A fixed point number just means that there are a fixed number of digits after the decimal point. A floating point number allows for a varying number of digits after the decimal point.

For example, if you have a way of storing numbers that requires exactly four digits after the decimal point, then it is fixed point. Without that restriction it is floating point.

Often, when fixed point is used, the programmer actually uses an integer and then makes the assumption that some of the digits are beyond the decimal point. For example, I might want to keep two digits of precision, so a value of 100 means actually means 1.00, 101 means 1.01, 12345 means 123.45, etc.

Floating point numbers are more general purpose because they can represent very small or very large numbers in the same way, but there is a small penalty in having to have extra storage for where the decimal place goes.

Another possibility:

df <- df[, setdiff(names(df), c("a", "c"))]

or

df <- df[, grep('^(a|c)$', names(df), invert=TRUE)]

You can even use this one. worked well for me

$("#registerform").attr("action", "register.php?btnsubmit=Save") 
$('#registerform').submit();

this will submit btnsubmit =Save as GET value to register.php form.

Tips and tricks

less

Why are you using editors to just look at a (large) file?

Under *nix or Cygwin, just use less. (There is a famous saying – "less is more, more or less" – because "less" replaced the earlier Unix command "more", with the addition that you could scroll back up.) Searching and navigating under less is very similar to Vim, but there is no swap file and little RAM used.

There is a Win32 port of GNU less. See the "less" section of the answer above.

Perl

Perl is good for quick scripts, and its .. (range flip-flop) operator makes for a nice selection mechanism to limit the crud you have to wade through.

For example:

$ perl -n -e 'print if ( 1000000 .. 2000000)' humongo.txt | less

This will extract everything from line 1 million to line 2 million, and allow you to sift the output manually in less.

Another example:

$ perl -n -e 'print if ( /regex one/ .. /regex two/)' humongo.txt | less

This starts printing when the "regular expression one" finds something, and stops when the "regular expression two" find the end of an interesting block. It may find multiple blocks. Sift the output...

logparser

This is another useful tool you can use. To quote the Wikipedia article:

logparser is a flexible command line utility that was initially written by Gabriele Giuseppini, a Microsoft employee, to automate tests for IIS logging. It was intended for use with the Windows operating system, and was included with the IIS 6.0 Resource Kit Tools. The default behavior of logparser works like a "data processing pipeline", by taking an SQL expression on the command line, and outputting the lines containing matches for the SQL expression.

Microsoft describes Logparser as a powerful, versatile tool that provides universal query access to text-based data such as log files, XML files and CSV files, as well as key data sources on the Windows operating system such as the Event Log, the Registry, the file system, and Active Directory. The results of the input query can be custom-formatted in text based output, or they can be persisted to more specialty targets like SQL, SYSLOG, or a chart.

Example usage:

C:\>logparser.exe -i:textline -o:tsv "select Index, Text from 'c:\path\to\file.log' where line > 1000 and line < 2000"
C:\>logparser.exe -i:textline -o:tsv "select Index, Text from 'c:\path\to\file.log' where line like '%pattern%'"

The relativity of sizes

100 MB isn't too big. 3 GB is getting kind of big. I used to work at a print & mail facility that created about 2% of U.S. first class mail. One of the systems for which I was the tech lead accounted for about 15+% of the pieces of mail. We had some big files to debug here and there.

And more...

Feel free to add more tools and information here. This answer is community wiki for a reason! We all need more advice on dealing with large amounts of data...

Based on the previous answer,

from urllib.request import Request, urlopen       
#specify url
url = 'https://xyz/xyz'
req = Request(url, headers={'User-Agent': 'XYZ/3.0'})
response = urlopen(req, timeout=20).read()

This worked for me by extending the timeout.

Functional Interface:

• Introduced in Java 8
• Interface that contains a "single abstract" method.

Example 1:

   interface CalcArea {   // --functional interface
        double calcArea(double rad);
    }           

Example 2:

interface CalcGeometry { // --functional interface
    double calcArea(double rad);
    default double calcPeri(double rad) {
        return 0.0;
    }
}       

Example 3:

interface CalcGeometry {  // -- not functional interface
    double calcArea(double rad);
    double calcPeri(double rad);
}   

Java8 annotation -- @FunctionalInterface

• Annotation check that interface contains only one abstract method. If not, raise error.
• Even though @FunctionalInterface missing, it is still functional interface (if having single abstract method). The annotation helps avoid mistakes.
• Functional interface may have additional static & default methods.
• e.g. Iterable<>, Comparable<>, Comparator<>.

Applications of Functional Interface:

• Method references
• Lambda Expression
• Constructor references

To learn functional interfaces, learn first default methods in interface, and after learning functional interface, it will be easy to you to understand method reference and lambda expression

Koala_dev's answer will work, but in case you are wondering this is the reason why it works:

To Fix The "Missing "server" JVM at C:\Program Files\Java\jre7\bin\server\jvm­­.dll, please install or use the JRE or JDK that contains these missing components.

Follow these steps:

Go to oracle.com and install Java JRE7 (Check if Java 6 is not installed already)

After that, go to C:/Program files/java/jre7/bin

Here, create an folder called Server

Now go into the C:/Program files/java/jre7/bin/client folder

Copy all the data in this folder into the new C:/Program files/java/jre7/bin/Server folder

In my case the problem was using the language tag "en_US" in Locale.forLanguageTag(..) instead of "en-US" - use a dash instead of underline!

Also use Locale.forLanguageTag("en-US") instead of new Locale("en_US") or new Locale("en_US") to define a language ("en") with a region ("US") - but new Locale("en") works.

vscode

I use vscode for java and it works pretty much the same as visual studio except you use comments:

//#region name

//code

//#endregion

The Path to your Storage disk would be :

$storagePath  = Storage::disk('local')->getDriver()->getAdapter()->getPathPrefix()

I don't know any shorter solutions to that...

You could share the $storagePath to your Views and then just call

$storagePath."/myImg.jpg";

I have just been faced with the same challenge, but I thought "Why programming this in Python if you can solve it with a simple "grep"?, which led to the following Python code:

import subprocess
from subprocess import PIPE

try:
  output1, errors1 = subprocess.Popen(["c:\\cygwin\\bin\\grep", "-Fvf" ,"c:\\file1.txt", "c:\\file2.txt"], shell=True, stdout=PIPE, stderr=PIPE).communicate();
  output2, errors2 = subprocess.Popen(["c:\\cygwin\\bin\\grep", "-Fvf" ,"c:\\file2.txt", "c:\\file1.txt"], shell=True, stdout=PIPE, stderr=PIPE).communicate();
  if (len(output1) + len(output2) + len(errors1) + len(errors2) > 0):
    print ("Compare result : There are differences:");
    if (len(output1) + len(output2) > 0):
      print ("  Output differences : ");
      print (output1);
      print (output2);
    if (len(errors1) + len(errors2) > 0):
      print (" Errors : ");
      print (errors1);
      print (errors2);
  else:
    print ("Compare result : Both files are equal");
except Exception as ex:
  print("Compare result : Exception during comparison");
  print(ex);
  raise;

The trick behind this is the following: grep -Fvf file1.txt file2.txt verifies if all entries in file2.txt are present in file1.txt. By doing this in both directions we can see if the content of both files are "equal". I put "equal" between quotes because duplicate lines are disregarded in this way of working.

Obviously, this is just an example: you can replace grep by any commandline file comparison tool.

I had the same problem and it kept me up for days. At the end, I realised that my URL pointing to the app was wrong altogether. example:

URL: 'http://api.example.com/'
URL: 'https://api.example.com/'.

If it's http or https verify.
Check the redirecting URL and make sure it's the same thing you're passing along.

I've solved the issue on one of my websites by explicitly setting the width of the body in javascript by the viewport size minus the width of the scrollbar. I use a jQuery based function documented here to determine the width of the scrollbar.

<body id="bodyid>

var bodyid = document.getElementById('bodyid');
bodyid.style.width = window.innerWidth - scrollbarWidth() + "px";

As other have said, you want to use either puts or p. Why? Is that magic?

Actually not. A rails console is, under the hood, an IRB, so all you can do in IRB you will be able to do in a rails console. Since for printing in an IRB we use puts, we use the same command for printing in a rails console.

You can actually take a look at the console code in the rails source code. See the require of irb? :)

It's going to be locale-dependent. Different locale, different default encoding.

The problem can also be the ordering of your style sheet imports. I had to move my custom style sheet import below the bootstrap import.

What you have from the server is a string like below:

var data = '[{"id":"197","category":"Damskie"},{"id":"198","category":"M\u0119skie"}]';

Then you can use JSON.parse function to change it to an object. Then you access the category like below:

var dataObj = JSON.parse(data);

console.log(dataObj[0].category); //will return Damskie
console.log(dataObj[1].category); //will return Meskie

Try dir /b, for bare format.

dir /? will show you documentation of what you can do with the dir command. Here is the output from my Windows 7 machine:

Indeed, just as commented by Tim Williams, the way to make it work is pre-formatting as text. Thus, to do it all via VBA, just do that:

Cells(1, 1).NumberFormat = "@"
Cells(1, 1).Value = "1234,56"

You can simply place a forward declaration of your second() function in your main.cpp above main(). If your second.cpp has more than one function and you want all of it in main(), put all the forward declarations of your functions in second.cpp into a header file and #include it in main.cpp.

Like this-

Second.h:

void second();
int third();
double fourth();

main.cpp:

#include <iostream>
#include "second.h"
int main()
{
    //.....
    return 0;
}

second.cpp:

void second()
{
    //...
}

int third()
{ 
    //...
    return foo;
}

double fourth()
{ 
    //...
    return f;
}

Note that: it is not necessary to #include "second.h" in second.cpp. All your compiler need is forward declarations and your linker will do the job of searching the definitions of those declarations in the other files.

This function cannot be run from the command line as it returns a value which will go unhanded. You can remove the return and use print instead

The standard C library provides timespec_get. It can tell time up to nanosecond precision, if the system supports. Calling it, however, takes a bit more effort because it involves a struct. Here's a function that just converts the struct to a simple 64-bit integer so you can get time in milliseconds.

#include <stdio.h>
#include <inttypes.h>
#include <time.h>

int64_t millis()
{
    struct timespec now;
    timespec_get(&now, TIME_UTC);
    return ((int64_t) now.tv_sec) * 1000 + ((int64_t) now.tv_nsec) / 1000000;
}

int main(void)
{
    printf("Unix timestamp with millisecond precision: %" PRId64 "\n", millis());
}

Unlike clock, this function returns a Unix timestamp so it will correctly account for the time spent in blocking functions, such as sleep.

Clear:both gives you that space between them.

For example your code:

  <div style="float:left">Hello</div>
  <div style="float:right">Howdy dere pardner</div>

Will currently display as :

Hello  ...................   Howdy dere pardner

If you add the following to above snippet,

  <div style="clear:both"></div>

In between them it will display as:

Hello ................ 
                       Howdy dere pardner

giving you that space between hello and Howdy dere pardner.

you can use <br> tag in your string for show in html pages

If you want to allow a comma delimiter which will pass the following test cases:

0,00  => true
0.00  => true
01,00 => true
01.00 => true
0.000 => false
0-01  => false

then use this:

^\d+(\.|\,)\d{2}$

In my case it acts like a <div> or <span> however even <span> messes up with my AngularFlex styling but ng-container doesn't.

With this command you will see all changes in the repository path/to/repo that were committed in revision <revision>:

svn diff -c <revision> path/to/repo

The -c indicates that you would like to look at a changeset, but there are many other ways you can look at diffs and changesets. For example, if you would like to know which files were changed (but not how), you can issue

svn log -v -r <revision>

Or, if you would like to show at the changes between two revisions (and not just for one commit):

svn diff -r <revA>:<revB> path/to/repo

Have a look at Select2 for Bootstrap. It should be able to do everything you need.

Another good option is Selectize.js. It feels a bit more native to Bootstrap.

You can use sum to sum the elements of a list, however if your list is coming from raw_input, you probably want to convert the items to int or float first:

l = raw_input().split(' ')
sum(map(int, l))

Lists in Scala are not designed to be modified. In fact, you can't add elements to a Scala List; it's an immutable data structure, like a Java String. What you actually do when you "add an element to a list" in Scala is to create a new List from an existing List. (Source)

Instead of using lists for such use cases, I suggest to either use an ArrayBuffer or a ListBuffer. Those datastructures are designed to have new elements added.

Finally, after all your operations are done, the buffer then can be converted into a list. See the following REPL example:

scala> import scala.collection.mutable.ListBuffer
import scala.collection.mutable.ListBuffer

scala> var fruits = new ListBuffer[String]()
fruits: scala.collection.mutable.ListBuffer[String] = ListBuffer()

scala> fruits += "Apple"
res0: scala.collection.mutable.ListBuffer[String] = ListBuffer(Apple)

scala> fruits += "Banana"
res1: scala.collection.mutable.ListBuffer[String] = ListBuffer(Apple, Banana)

scala> fruits += "Orange"
res2: scala.collection.mutable.ListBuffer[String] = ListBuffer(Apple, Banana, Orange)

scala> val fruitsList = fruits.toList
fruitsList: List[String] = List(Apple, Banana, Orange)

This answer might not be 100% relevant to the question. But it does address the problem. I found this simple way of achieving this requirement. Code goes below:

<a href="@Url.Action("Display", "Customer")?custId={{cust.Id}}"></a>

In the above example {{cust.Id}} is an AngularJS variable. However one can replace it with a JavaScript variable.

I haven't tried passing multiple variables using this method but I'm hopeful that also can be appended to the Url if required.

Set the auto complete:

$("#searchBox").autocomplete({
    source: queryDB
});

The source function that gets the data:

function queryDB(request, response) {
    var query = request.term;
    var data = getDataFromDB(query);
    response(data); //puts the results on the UI
}

meda's answer is completely legit, but when I copied the code I got an error!

Somewhere in the "php://input" there's an invalid character (maybe one of the quotes?).

When I typed the "php://input" code manually, it worked. Took me a while to figure out!

curl sends POST requests with the default content type of application/x-www-form-urlencoded. If you want to send a JSON request, you will have to specify the correct content type header:

$ curl -vX POST http://server/api/v1/places.json -d @testplace.json \
--header "Content-Type: application/json"

But that will only work if the server accepts json input. The .json at the end of the url may only indicate that the output is json, it doesn't necessarily mean that it also will handle json input. The API documentation should give you a hint on whether it does or not.

The reason you get a 401 and not some other error is probably because the server can't extract the auth_token from your request.

Try

//book[title/@lang = 'it']

This reads:

• get all book elements
  • that have at least one title
    • which has an attribute lang
      • with a value of "it"

You may find this helpful — it's an article entitled "XPath in Five Paragraphs" by Ronald Bourret.

But in all honesty, //book[title[@lang='it']] and the above should be equivalent, unless your XPath engine has "issues." So it could be something in the code or sample XML that you're not showing us -- for example, your sample is an XML fragment. Could it be that the root element has a namespace, and you aren't counting for that in your query? And you only told us that it didn't work, but you didn't tell us what results you did get.

It's hard to tell for sure because you haven't included many details, but I think what is going on is that there are <% ... %> code blocks inside your Page.Header (which is referring to <head runat="server"> - possibly in a master page). Therefore, when you try to add an item to the Controls collection of that control, you get the error message in the title of this question.

If I'm right, then the workaround is to wrap a <asp:placeholder runat="server"> tag around the <% ... %> code block. This makes the code block a child of the Placeholder control, instead of being a direct child of the Page.Header control, but it doesn't change the rendered output at all. Now that the code block is not a direct child of Page.Header you can add things to the header's controls collection without error.

Again, there is a code block somewhere or you wouldn't be seeing this error. If it's not in your aspx page, then the first place I would look is the file referenced by the MasterPageFile attribute at the top of your aspx.

Well you're right, REST is stateless. If you use a session the processing will become stateful, subsequent requests will be able to use state (from a session).

In order for a session to be rehydrated, you'll need to supply a key to associate the state. In a normal asp.net application that key is supplied by using a cookie (cookie-sessions) or url parameter (cookieless sessions).

If you need a session forget rest, sessions are irrelevant in REST based designs. If you need a session for validation then use a token or authorise by IP addresses.

Some handy quick functions (if you're not using Boost):

template<typename T>
std::string ToString(const T& v)
{
    std::ostringstream ss;
    ss << v;
    return ss.str();
}

template<typename T>
T FromString(const std::string& str)
{
    std::istringstream ss(str);
    T ret;
    ss >> ret;
    return ret;
}

Example:

int i = FromString<int>(s);
std::string str = ToString(i);

Works for any streamable types (floats etc). You'll need to #include <sstream> and possibly also #include <string>.

I find it more convenient to make a connection using a procedural programming language (like Python) and do these types of queries.

                                  , database="myDB"
                                  , host="[ENDPOINT]")
cursor_psql = connection_psql.cursor()

myList = [...]
for item in myList:
  cursor_psql.execute('''
    -- The query goes here
  ''')

connection_psql.commit()
cursor_psql.close()

I had something similar when passing a script to a function with invoke-command. I ran the command in single quotes instead of double quotes, because it then becomes a string literal. 'Set-Mailbox $sourceUser -LitigationHoldEnabled $false -ElcProcessingDisabled $true';

I had this problem in android and i use this way (Work for me):

String test = null;
if(test == "null"){

But in java code I use :

String test = null;
if(test == null){
// Do work
}

And :

private Integer compareDateStrings(BeanToDoTask arg0, BeanToDoTask arg1, String strProperty) {
    String strDate0 = BeanUtils.getProperty(arg0, strProperty);_logger.debug("strDate0 = " + strDate0);
    String strDate1 = BeanUtils.getProperty(arg1, strProperty);_logger.debug("strDate1 = " + strDate1);
    return compareDateStrings(strDate0, strDate1);
}

private Integer compareDateStrings(String strDate0, String strDate1) {
    int cmp = 0;
    if (isEmpty(strDate0)) {
        if (isNotEmpty(strDate1)) {
            cmp = -1;
        } else {

Yes, open a postscript() device with a filename ending in .eps, do your plot(s) and call dev.off().

It is common to get this issue. I cannot set any specific Java home in my system as I have 2 different version of Java (Java 6 and Java 7) for different environment. To resolve the issue, I included the JDK path in the run configuration when opening the build.xml file. This way, 2 different build files use 2 different Java version for build. I think there might be a better solution to this problem but at least the above approach avoid setting the JAVA_HOME variable.

OK why so complex!

package main

import (
    "fmt"
    "math/rand"
    "time"
)

func main() {
    rand.Seed( time.Now().UnixNano())
    var bytes int

    for i:= 0 ; i < 10 ; i++{ 
        bytes = rand.Intn(6)+1
        fmt.Println(bytes)
        }
    //fmt.Println(time.Now().UnixNano())
}

This is based off the dystroy's code but fitted for my needs.

It's die six (rands ints 1 =< i =< 6)

func randomInt (min int , max int  ) int {
    var bytes int
    bytes = min + rand.Intn(max)
    return int(bytes)
}

The function above is the exactly same thing.

I hope this information was of use.

I solved this problem by editing /usr/local/zend/etc/php.ini.

(found it by doing netstat -nlp ¦ grep apache, then strace -p somepid ¦ grep php.ini).

At the end of the file, I added:

extension=/usr/lib/php5/20090626+lfs/mysqli.so
extension=/usr/lib/php5/20090626+lfs/mcrypt.so

Adding it without the path did not work.

Then after a restart it worked.

You can do something like this

Session session = app.factory.openSession();
CriteriaBuilder builder = session.getCriteriaBuilder();
CriteriaQuery query = builder.createQuery();
Root<Users> root = query.from(Users.class);
query.select(root.get("firstname"));
String name = session.createQuery(query).getSingleResult();

where you can change "firstname" with the name of the column you want.

Also constructor based initialisation will not work as intended whenever some kind of proxying or remoting is involved.

The ct will get called whenever an EJB gets deserialized, and whenever a new proxy gets created for it...

String date = "11-02-2000";
String[] input = date.split("-");
int day = Integer.valueOf(input[0]);
int month = Integer.valueOf(input[1]);
int year = Integer.valueOf(input[2]);
Calendar cal=Calendar.getInstance();
cal.set(Calendar.YEAR,year);
cal.set(Calendar.MONTH,month-1);
cal.set(Calendar.DATE, day);
//since month number starts from 0 (i.e jan 0, feb 1), 
//we are subtracting original month by 1
int days = cal.getActualMaximum(Calendar.DAY_OF_MONTH);
System.out.println(days);

This is what's killing you:

task.Wait();

That's blocking the UI thread until the task has completed - but the task is an async method which is going to try to get back to the UI thread after it "pauses" and awaits an async result. It can't do that, because you're blocking the UI thread...

There's nothing in your code which really looks like it needs to be on the UI thread anyway, but assuming you really do want it there, you should use:

private async void Button_Click(object sender, RoutedEventArgs 
{
    Task<List<MyObject>> task = GetResponse<MyObject>("my url");
    var items = await task;
    // Presumably use items here
}

Or just:

private async void Button_Click(object sender, RoutedEventArgs 
{
    var items = await GetResponse<MyObject>("my url");
    // Presumably use items here
}

Now instead of blocking until the task has completed, the Button_Click method will return after scheduling a continuation to fire when the task has completed. (That's how async/await works, basically.)

Note that I would also rename GetResponse to GetResponseAsync for clarity.

perhaps this is what you're looking for: https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/colors.xml

In C#, the common mutex used is the Monitor. The type is 'System.Threading.Monitor'. It may also be used implicitly via the 'lock(Object)' statement. One example of its use is when constructing a Singleton class.

private static readonly Object instanceLock = new Object();
private static MySingleton instance;
public static MySingleton Instance
{
    lock(instanceLock)
    {
        if(instance == null)
        {
            instance = new MySingleton();
        }
        return instance;
    }
}

The lock statement using the private lock object creates a critical section. Requiring each thread to wait until the previous is finished. The first thread will enter the section and initialize the instance. The second thread will wait, get into the section, and get the initialized instance.

Any sort of synchronization of a static member may use the lock statement similarly.

i have used this and solved my

The following code can be used to read the input string from a user. But it's space is limited to 64.

char word[64] = { '\0' };  //initialize all elements with '\0'
int i = 0;
while ((word[i] != '\n')&& (i<64))
{
    scanf_s("%c", &word[i++], 1);
}

Count() is an extension method introduced by LINQ while the Count property is part of the List itself (derived from ICollection). Internally though, LINQ checks if your IEnumerable implements ICollection and if it does it uses the Count property. So at the end of the day, there's no difference which one you use for a List.

To prove my point further, here's the code from Reflector for Enumerable.Count()

public static int Count<TSource>(this IEnumerable<TSource> source)
{
    if (source == null)
    {
        throw Error.ArgumentNull("source");
    }
    ICollection<TSource> is2 = source as ICollection<TSource>;
    if (is2 != null)
    {
        return is2.Count;
    }
    int num = 0;
    using (IEnumerator<TSource> enumerator = source.GetEnumerator())
    {
        while (enumerator.MoveNext())
        {
            num++;
        }
    }
    return num;
}

i know this question is old, but hopefully it will help someone. i found a great plugin for those who are using PyCharm IDE: string-manipulation that can easily escape double quotes (and many more...), this plugin is great for cases where you know what the string going to be. for other cases, using json.dumps(string) will be the recommended solution

str_to_escape = 'my string with "double quotes" blablabla'

after_escape = 'my string with \"double quotes\" blablabla'

In addition to @Greg Bacon answer, in case binary files were added to the index and were part of the stash using

git stash show -p | git apply --reverse

may result in

error: cannot apply binary patch to '<YOUR_NEW_FILE>' without full index line

Adding --binary resolves the issue, but unfortunately haven't figured out why yet.

let my_u8: u8 = "42".parse::<u8>().unwrap();
let my_u32: u32 = "42".parse::<u32>().unwrap();

// or, to be safe, match the `Err`
match "foobar".parse::<i32>() {
  Ok(n) => do_something_with(n),
  Err(e) => weep_and_moan(),
}

str::parse::<u32> returns a Result<u32, core::num::ParseIntError> and Result::unwrap "Unwraps a result, yielding the content of an Ok [or] panics if the value is an Err, with a panic message provided by the Err's value."

str::parse is a generic function, hence the type in angle brackets.

Embed the video player and use CSS to hide the video. If you do it properly you may even be able to hide only the video and not the controls below it.

However, I'd recommend against it, because it will be a violation of YouTube TOS. Use your own server instead if you really want to play only audio.

The code that has to be executed for both alternatives is so similar that you can’t predict a result reliably. The underlying object structure might differ but that’s no challenge to the hotspot optimizer. So it depends on other surrounding conditions which will yield to a faster execution, if there is any difference.

Combining two filter instances creates more objects and hence more delegating code but this can change if you use method references rather than lambda expressions, e.g. replace filter(x -> x.isCool()) by filter(ItemType::isCool). That way you have eliminated the synthetic delegating method created for your lambda expression. So combining two filters using two method references might create the same or lesser delegation code than a single filter invocation using a lambda expression with &&.

But, as said, this kind of overhead will be eliminated by the HotSpot optimizer and is negligible.

In theory, two filters could be easier parallelized than a single filter but that’s only relevant for rather computational intense tasks¹.

So there is no simple answer.

The bottom line is, don’t think about such performance differences below the odor detection threshold. Use what is more readable.

    cellTableViewFooter.frame = CGRectMake(0, 0, self.tableView.bounds.width, self.heightCache[TableViewController.tableViewFooterCustomCellIdentifier]!)
    self.tableView.tableFooterView = cellTableViewFooter

join tableB b on isnull(a.colID,'') = isnull(b.colId,'')

You're trying to assign the result of the add operation to resultArrGame, and add can either return true or false, depending on if the operation was successful or not. What you want is probably just:

resultArrGame.add(txt.Game.getText().toString());

By an "anonymous class", I take it you mean anonymous inner class.

An anonymous inner class can come useful when making an instance of an object with certain "extras" such as overriding methods, without having to actually subclass a class.

I tend to use it as a shortcut for attaching an event listener:

button.addActionListener(new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent e) {
        // do something
    }
});

Using this method makes coding a little bit quicker, as I don't need to make an extra class that implements ActionListener -- I can just instantiate an anonymous inner class without actually making a separate class.

I only use this technique for "quick and dirty" tasks where making an entire class feels unnecessary. Having multiple anonymous inner classes that do exactly the same thing should be refactored to an actual class, be it an inner class or a separate class.

As mentioned by @Rafael Almeida, the problem you are having is caused by an untrusted SSL certificate. In my case, the SSL certificate was untrusted by my server. To get around this without compromising security, I downloaded the certificate, and installed it on the server (by simply double clicking on the .crt file and then Install Certificate...).

Given your representation, your function is as efficient as can be done. Of course, as noted by others (and as practiced in languages older than Lua), the solution to your real problem is to change representation. When you have tables and you want sets, you turn tables into sets by using the set element as the key and true as the value. +1 to interjay.

I have experimented many of the backslash escape characters. \n which is a new line feed can be put anywhere to bring the effect. One important thing to remember while using this character is that the operating system of the machine we are using might affect the output. As an example, I have printed a bunch of escape character and displayed the result as follow to proof that the OS will affect the output.

Code:

#include <stdio.h>
int main(void){
    printf("Hello World!");
    printf("Goodbye \a");
    printf("Hi \b");
    printf("Yo\f");
    printf("What? \t");
    printf("pewpew");
    return 0;
}

In summary, it has to pause the programs execution and make a system call and allocate unnecessary resources when you could be using something as simple as cin.get(). People use System("PAUSE") because they want the program to wait until they hit enter to they can see their output. If you want a program to wait for input, there are built in functions for that which are also cross platform and less demanding.

EL (Expressions Languages) evaluates 0 as a Long and thus goes looking for a Long as the key in the map. ie it evaluates:

map.get(new Long(0))

As a Long is never equal to an Integer object, it does not find the entry in the map.
That's it in a nutshell.

Update since May 2009 (EL 2.2)

Dec 2009 saw the introduction of EL 2.2 with JSP 2.2 / Java EE 6, with a few differences compared to EL 2.1.
It seems ("EL Expression parsing integer as long") that:

you can call the method intValue on the Long object self inside EL 2.2:

<c:out value="${map[(1).intValue()]}"/>

That could be a good workaround here (also mentioned below in Tobias Liefke's answer)

Original answer:

EL uses the following wrappers:

Terms                  Description               Type
null                   null value.               -
123                    int value.                java.lang.Long
123.00                 real value.               java.lang.Double
"string" ou 'string'   string.                   java.lang.String
true or false          boolean.                  java.lang.Boolean

 <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

 <%@ page import="java.util.*" %>

 <h2> Server Info</h2>

  <h3>Looking up map in JSTL - integer vs long </h3>

  This page demonstrates how JSTL maps interact with different types used for keys in a map.
  Specifically the issue relates to autoboxing by java using map.put(1, "MyValue") and attempting to display it as ${myMap[1]}
  The map "myMap" consists of four entries with different keys: A String, an Integer, a Long and an entry put there by AutoBoxing Java 5 feature.       

  <table border="1">
    <tr><th>Key</th><th>value</th><th>Key Class</th></tr>
    <c:forEach var="entry" items="${myMap}" varStatus="status">
    <tr>      
      <td>${entry.key}</td>
      <td>${entry.value}</td>
      <td>${entry.key.class}</td>
    </tr>
    </c:forEach>
</table>

    <h4> Accessing the map</h4>    
    Evaluating: ${"${myMap['2']}"} = <c:out value="${myMap['2']}"/><br>
    Evaluating: ${"${myMap[2]}"}   = <c:out value="${myMap[2]}"/><br>    
    Evaluating: ${"${myMap[42]}"}   = <c:out value="${myMap[42]}"/><br>    

    <p>
    As you can see, the EL Expression for the literal number retrieves the value against the java.lang.Long entry in the map.
    Attempting to access the entry created by autoboxing fails because a Long is never equal to an Integer
    <p>

    lifeInteger = <%= lifeInteger %><br/>
    lifeLong = <%= lifeLong %><br/>
    lifeInteger.equals(lifeLong) : <%= lifeInteger.equals(lifeLong) %> <br>

Your returned format will be limited by the return type you declare. So yes, you can declare the property as a string and return the formatted value of something. In the "get" you can put whatever data retrieval code you need. So if you need to access some numeric value, simply put your return statement as:

    private decimal _myDecimalValue = 15.78m;
    public string MyFormattedValue
    {
        get { return _myDecimalValue.ToString("c"); }
        private set;  //makes this a 'read only' property.
    }

Global exclusions look like they're being worked on, but until then...

From the Sonatype maven reference (bottom of the page):

Dependency management in a top-level POM is different from just defining a dependency on a widely shared parent POM. For starters, all dependencies are inherited. If mysql-connector-java were listed as a dependency of the top-level parent project, every single project in the hierarchy would have a reference to this dependency. Instead of adding in unnecessary dependencies, using dependencyManagement allows you to consolidate and centralize the management of dependency versions without adding dependencies which are inherited by all children. In other words, the dependencyManagement element is equivalent to an environment variable which allows you to declare a dependency anywhere below a project without specifying a version number.

As an example:

  <dependencies>
    <dependency>
      <groupId>commons-httpclient</groupId>
      <artifactId>commons-httpclient</artifactId>
      <version>3.1</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-beans</artifactId>
      <version>3.0.5.RELEASE</version>
    </dependency>
  </dependencies>
  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-beans</artifactId>
        <exclusions>
          <exclusion>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
          </exclusion>
        </exclusions>
      </dependency>
      <dependency>
        <groupId>commons-httpclient</groupId>
        <artifactId>commons-httpclient</artifactId>
        <exclusions>
          <exclusion>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
          </exclusion>
        </exclusions>
      </dependency>
    </dependencies>
  </dependencyManagement>

It doesn't make the code less verbose overall, but it does make it less verbose where it counts. If you still want it less verbose you can follow these tips also from the Sonatype reference.

You can also try this in plain javascript

"1234".slice(0,-1)

the negative second parameter is an offset from the last character, so you can use -2 to remove last 2 characters etc

To find all files that are modified today only (since start of day only, i.e. 12 am), in current directory and its sub-directories:

touch -t `date +%m%d0000` /tmp/$$
find . -type f -newer /tmp/$$
rm /tmp/$$

Source

(int) add: (int) numberOne plus: (int) numberTwo ;
(returnType) functionPrimaryName : (returnTypeOfArgumentOne) argumentName functionSecondaryNa

me:

(returnTypeOfSecontArgument) secondArgumentName ;

as in other languages we use following syntax void add(int one, int second) but way of assigning arguments in OBJ_c is different as described above

you can try to use cv2 like this

import cv2

image= cv2.imread('image page')

cv2.imshow('image', image)

cv2.waitKey(0)

cv2.destroyAllWindows()

A very big difference is that ":hover" state is automatically deactivated when the mouse moves out of the element. As a result any styles that are applied on hover are automatically reversed. On the other hand, with the javascript approach, you would have to define both "onmouseover" and "onmouseout" events. If you only define "onmouseover" the styles that are applied "onmouseover" will persist even after you mouse out unless you have explicitly defined "onmouseout".

MDN: https://developer.mozilla.org/en/DOM/window.location

It seems that you will get the same result for both, but hostname contains clear host name without brackets or port number.

You can also use bellow code for pass data using ajax.

var dataString = "album" + title;
$.ajax({  
    type: 'POST',  
    url: 'test.php', 
    data: dataString,
    success: function(response) {
        content.html(response);
    }
});

To add global include path use custom command for qmake in Projects/Build/Build Steps section in "Additional arguments" like this: "QT+=your_qt_modules" "DEFINES+=your_defines"

I think that you can use any command from *.pro files in that way.

Don't forget the option "-o", which lets you download anywhere you want, although you have to create "archives", "lock" and "partial" first (the command prints what's needed).

apt-get install -d -o=dir::cache=/tmp whateveryouwant

there are two way:

First :

Inside your CD of SQL Server 2012

you can go to this path \redist\VisualStudioShell.

And you most install this file VS10sp1-KB983509.msp.

After several minutes your problem fix.

Restart your computer and then fire SetUp of SQL Server 2012.

See this picture.

Secound :

But if you want download online Service Pack 1 view This Link

And press download.

After download run this exe file and let it download and fix your VS2010 to VS2010 SP1.

And then restart your windows.

After this operation you can install SQL Server 2012

You can convert the int back to an enumeration member with a simple cast, and then call ToString():

int value = GetValueFromDb();
var enumDisplayStatus = (EnumDisplayStatus)value;
string stringValue = enumDisplayStatus.ToString();

Gist with log rotation: https://gist.github.com/barsv/85c93b599a763206f47aec150fb41ca0

Usage:

Write-Log "debug message"
Write-Log "info message" "INFO"

Parameters in the URL are GET parameters, a request body, if present, is POST data. So your basic premise is by definition not achievable.

You should choose whether to use POST or GET based on the action. Any destructive action, i.e. something that permanently changes the state of the server (deleting, adding, editing) should always be invoked by POST requests. Any pure "information retrieval" should be accessible via an unchanging URL (i.e. GET requests).

To make a POST request, you need to create a <form>. You could use Javascript to create a POST request instead, but I wouldn't recommend using Javascript for something so basic. If you want your submit button to look like a link, I'd suggest you create a normal form with a normal submit button, then use CSS to restyle the button and/or use Javascript to replace the button with a link that submits the form using Javascript (depending on what reproduces the desired behavior better). That'd be a good example of progressive enhancement.

I had the same question and I finally found the answer:

You need to handle BOTH the SelectionChanged event and the DropDownClosed like this:

In XAML:

<ComboBox Name="cmbSelect" SelectionChanged="ComboBox_SelectionChanged" DropDownClosed="ComboBox_DropDownClosed">
    <ComboBoxItem>1</ComboBoxItem>
    <ComboBoxItem>2</ComboBoxItem>
    <ComboBoxItem>3</ComboBoxItem>
</ComboBox>

In C#:

private bool handle = true;
private void ComboBox_DropDownClosed(object sender, EventArgs e) {
  if(handle)Handle();
  handle = true;
}

private void ComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e) {
  ComboBox cmb = sender as ComboBox;
  handle = !cmb.IsDropDownOpen;
  Handle();
}

private void Handle() {
  switch (cmbSelect.SelectedItem.ToString().Split(new string[] { ": " }, StringSplitOptions.None).Last())
  { 
      case "1":
          //Handle for the first combobox
          break;
      case "2":
          //Handle for the second combobox
          break;
      case "3":
          //Handle for the third combobox
          break;
  }
}

The most beautiful answer is... Extend jQuery with this function...

$.fn.extend({
    toggleText: function(a, b){
        return this.text(this.text() == b ? a : b);
    }
});

HTML:

<button class="example"> Initial </button>

Use:

$(".example").toggleText('Initial', 'Secondary');

I've used the logic ( x == b ? a : b ) in the case that the initial HTML text is slightly different (an extra space, period, etc...) so you'll never get a duplicate showing of the intended initial value

(Also why I purposely left spaces in the HTML example ;-)

Another possibility for HTML toggle use brought to my attention by Meules [below] is:

$.fn.extend({
        toggleHtml: function(a, b){
            return this.html(this.html() == b ? a : b);
        }
    });

HTML:

<div>John Doe was an unknown.<button id='readmore_john_doe'> Read More... </button></div>

Use:

$("readmore_john_doe").click($.toggleHtml(
    'Read More...', 
    'Until they found his real name was <strong>Doe John</strong>.')
);

(or something like this)

If your post keys have to be parsed and the keys are sequences with data, you can try this:

Post data example: Storeitem|14=data14

foreach($_POST as $key => $value){
    $key=Filterdata($key); $value=Filterdata($value);
    echo($key."=".$value."<br>");
}

then you can use strpos to isolate the end of the key separating the number from the key.

You just need to add this line to the window there:

exec (your stored proc name) (and possibly add parameters)

What is your stored proc called, and what parameters does it expect?

The .browser call has been removed in jquery 1.9 have a look at http://jquery.com/upgrade-guide/1.9/ for more details.

Because python checks in the directories in sequential order starting at the first directory in sys.path list, till it find the .py file it was looking for.

Ideally, the current directory or the directory of the script is the first always the first element in the list, unless you modify it, like you did. From documentation -

As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter. If the script directory is not available (e.g. if the interpreter is invoked interactively or if the script is read from standard input), path[0] is the empty string, which directs Python to search modules in the current directory first. Notice that the script directory is inserted before the entries inserted as a result of PYTHONPATH.

So, most probably, you had a .py file with the same name as the module you were trying to import from, in the current directory (where the script was being run from).

Also, a thing to note about ImportErrors , lets say the import error says - ImportError: No module named main - it doesn't mean the main.py is overwritten, no if that was overwritten we would not be having issues trying to read it. Its some module above this that got overwritten with a .py or some other file.

Example -

My directory structure looks like -

 - test
    - shared
         - __init__.py
         - phtest.py
  - testmain.py

Now From testmain.py , I call from shared import phtest , it works fine.

Now lets say I introduce a shared.py in test directory` , example -

 - test
    - shared
         - __init__.py
         - phtest.py
  - testmain.py 
  - shared.py

Now when I try to do from shared import phtest from testmain.py , I will get the error -

ImportError: cannot import name 'phtest'

As you can see above, the file that is causing the issue is shared.py , not phtest.py .

You can do something like this to read your nodes.

Also you can find some explanation in this page http://www.compoc.com/tuts/

<script type="text/javascript">
        var markers = null;
        $(document).ready(function () {
            $.get("File.xml", {}, function (xml){
              $('marker',xml).each(function(i){
                 markers = $(this);
              });

A simple and clean way: use np.argwhere to group the indices by element, rather than dimension as in np.nonzero(a) (i.e., np.argwhere returns a row for each non-zero element).

>>> a = np.arange(10)
>>> a
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
>>> np.argwhere(a>4)
array([[5],
       [6],
       [7],
       [8],
       [9]])

np.argwhere(a) is the same as np.transpose(np.nonzero(a)).

Note: You cannot use a(np.argwhere(a>4)) to get the corresponding values in a. The recommended way is to use a[(a>4).astype(bool)] or a[(a>4) != 0] rather than a[np.nonzero(a>4)] as they handle 0-d arrays correctly. See the documentation for more details. As can be seen in the following example, a[(a>4).astype(bool)] and a[(a>4) != 0] can be simplified to a[a>4].

Another example:

>>> a = np.array([5,-15,-8,-5,10])
>>> a
array([  5, -15,  -8,  -5,  10])
>>> a > 4
array([ True, False, False, False,  True])
>>> a[a > 4]
array([ 5, 10])
>>> a = np.add.outer(a,a)
>>> a
array([[ 10, -10,  -3,   0,  15],
       [-10, -30, -23, -20,  -5],
       [ -3, -23, -16, -13,   2],
       [  0, -20, -13, -10,   5],
       [ 15,  -5,   2,   5,  20]])
>>> a = np.argwhere(a>4)
>>> a
array([[0, 0],
       [0, 4],
       [3, 4],
       [4, 0],
       [4, 3],
       [4, 4]])
>>> [print(i,j) for i,j in a]
0 0
0 4
3 4
4 0
4 3

I was able to get the full text (99,208 chars) out of a NVARCHAR(MAX) column by selecting (Results To Grid) just that column and then right-clicking on it and then saving the result as a CSV file. To view the result open the CSV file with a text editor (NOT Excel). Funny enough, when I tried to run the same query, but having Results to File enabled, the output was truncated using the Results to Text limit.

The work-around that @MartinSmith described as a comment to the (currently) accepted answer didn't work for me (got an error when trying to view the full XML result complaining about "The '[' character, hexadecimal value 0x5B, cannot be included in a name").

I used this query and it worked for me:

CREATE EVENT `exec`
  ON SCHEDULE EVERY 5 SECOND
  STARTS '2013-02-10 00:00:00'
  ENDS '2015-02-28 00:00:00'
  ON COMPLETION NOT PRESERVE ENABLE
DO 
  call delete_rows_links();

Set This in OkHttpClient.Builder() Object

val httpClient = OkHttpClient.Builder()
        httpClient.connectTimeout(5, TimeUnit.MINUTES) // connect timeout

            .readTimeout(5, TimeUnit.MINUTES) // read timeout

The class Doctrine\ORM\EntityRepository implements Doctrine\Common\Collections\Selectable API.

The Selectable interface is very flexible and quite new, but it will allow you to handle comparisons and more complex criteria easily on both repositories and single collections of items, regardless if in ORM or ODM or completely separate problems.

This would be a comparison criteria as you just requested as in Doctrine ORM 2.3.2:

$criteria = new \Doctrine\Common\Collections\Criteria();
$criteria->where($criteria->expr()->gt('prize', 200));

$result = $entityRepository->matching($criteria);

The major advantage in this API is that you are implementing some sort of strategy pattern here, and it works with repositories, collections, lazy collections and everywhere the Selectable API is implemented.

This allows you to get rid of dozens of special methods you wrote for your repositories (like findOneBySomethingWithParticularRule), and instead focus on writing your own criteria classes, each representing one of these particular filters.

I couldn't always use pointer-events: none in my scenario, because I wanted both the overlay and the underlying element(s) to be clickable / selectable.

The DOM structure looked like this:

<div id="outerElement">
   <div id="canvas-wrapper">
      <canvas id="overlay"></canvas>
   </div>
   <!-- Omitted: element(s) behind canvas that should still be selectable -->
</div>

(The outerElement, canvas-wrapper and canvas elements have the same size.)

To make the elements behind the canvas act normally (e.g. selectable, editable), I used the following code:

canvasWrapper.style.pointerEvents = 'none';

outerElement.addEventListener('mousedown', event => {
    const clickedOnElementInCanvas = yourCheck // TODO: check if the event *would* click a canvas element.
    if (!clickedOnElementInCanvas) {

        // if necessary, add logic to deselect your canvas elements ...

        wrapper.style.pointerEvents = 'none';
        return true;
    }

    // Check if we emitted the event ourselves (avoid endless loop)
    if (event.isTrusted) {
        // Manually forward element to the canvas
        const mouseEvent = new MouseEvent(event.type, event);
        canvas.dispatchEvent(mouseEvent);
        mouseEvent.stopPropagation();
    }
    return true;
});

Some canvas objects also came with input fields, so I had to allow keyboard events, too. To do this, I had to update the pointerEvents property based on whether a canvas input field was currently focused or not:

onCanvasModified(canvas, () => {
    const inputFieldInCanvasActive = // TODO: Check if an input field of the canvas is active.
    wrapper.style.pointerEvents = inputFieldInCanvasActive  ? 'auto' : 'none';
});

While working with selected cells as shown by @tbur can be useful, it's also not the only option available.

You can use Range() like so:

If Worksheets("Sheet1").Range("A1").MergeCells Then
  Do something
Else
  Do something else
End If

Or:

If Worksheets("Sheet1").Range("A1:C1").MergeCells Then
  Do something
Else
  Do something else
End If

Alternately, you can use Cells():

If Worksheets("Sheet1").Cells(1, 1).MergeCells Then
  Do something
Else
  Do something else
End If

In xml file, put imeOptions="actionSearch" and inputType="text", maxLines="1":

<EditText
    android:id="@+id/search_box"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="@string/search"
    android:imeOptions="actionSearch"
    android:inputType="text"
    android:maxLines="1" />

Change start in angular.json to either "start": "ng serve --host 0.0.0.0" or "start": "lite-server" and run.Also check if you've installed angular/cli properly or not.

It happens that LINQ doesn't like properties such as DateTime.Date. It just can't convert to SQL queries. So I figured out a way of comparing dates using Jon's answer, but without that naughty DateTime.Date. Something like this:

var q = db.Games.Where(t => t.StartDate.CompareTo(DateTime.Today) >= 0).OrderBy(d => d.StartDate);

This way, we're comparing a full database DateTime, with all that date and time stuff, like 2015-03-04 11:49:45.000 or something like this, with a DateTime that represents the actual first millisecond of that day, like 2015-03-04 00:00:00.0000.

Any DateTime we compare to that DateTime.Today will return us safely if that date is later or the same. Unless you want to compare literally the same day, in which case I think you should go for Caesar's answer.

The method DateTime.CompareTo() is just fancy Object-Oriented stuff. It returns -1 if the parameter is earlier than the DateTime you referenced, 0 if it is LITERALLY EQUAL (with all that timey stuff) and 1 if it is later.

Java has two kind of Variables

a)
Class Level (Static) :
They are one per Class.Say you have Student Class and defined name as static variable.Now no matter how many student object you create all will have same name.

Object Level :
They belong to per Object.If name is non-static ,then all student can have different name.

b)
Class Level :
This variables are initialized on Class load.So even if no student object is created you can still access and use static name variable.

Object Level: They will get initialized when you create a new object ,say by new();

C)
Your Problem : Your class is Just loaded in JVM and you have called its main (static) method : Legally allowed.

Now from that you want to call an Object varibale : Where is the object ??

You have to create a Object and then only you can access Object level varibales.

This is an old post but still a problem within the Chrome dev tools. I find the best way to check mobile source locally is to open the site locally in Xcode's iOS Simulator. Then from there you open the Safari browser and enable dev tools, if you have not already done this (go to preferences -> advanced -> show develop menu in menu bar). Now you will see the develop option in the main menu and can go to develop -> iOS Simulator -> and the page you have open in Xcode's iOS Simulator will be there. Once you click on it, it will open the web inspector and you can edit as you would normally in the browser dev tools.

I'm afraid this solution will only work on a Mac though as it uses Xcode.

If you attach your code as a text file and your recipient(s) have "show attachments inline" option set (I believe it's set by default), Outlook should not mangle your code but it will be copy/paste-able directly from email.

Work's in Ubuntu 18.04

It's actually a sensible question. Here's the answer from Excel 2010 help:

"The Workbook object is a member of the Workbooks collection. The Workbooks collection contains all the Workbook objects currently open in Microsoft Excel."

So, since that workbook isn't open - at least I assume it isn't - it can't be set as a workbook object. If it was open you'd just set it like:

Set wbk = workbooks("Master Benchmark Data Sheet.xlsx")

This one never failed me:

one.sh:

LFILE=/tmp/one-`echo "$@" | md5sum | cut -d\  -f1`.pid
if [ -e ${LFILE} ] && kill -0 `cat ${LFILE}`; then
   exit
fi

trap "rm -f ${LFILE}; exit" INT TERM EXIT
echo $$ > ${LFILE}

$@

rm -f ${LFILE}

cron job:

* * * * * /path/to/one.sh <command>

If you add a $scope.$apply(); right after $scope.pluginsDisplayed.splice(index,1); then it works.

I am not sure why this is happening, but basically when AngularJS doesn't know that the $scope has changed, it requires to call $apply manually. I am also new to AngularJS so cannot explain this better. I need too look more into it.

I found this awesome article that explains it quite properly. Note: I think it might be better to use ng-click (docs) rather than binding to "mousedown". I wrote a simple app here (http://avinash.me/losh, source http://github.com/hardfire/losh) based on AngularJS. It is not very clean, but it might be of help.

One has pretty much control on which information from the traceback to be displayed/logged when catching exceptions.

The code

with open("not_existing_file.txt", 'r') as text:
    pass

would produce the following traceback:

Traceback (most recent call last):
  File "exception_checks.py", line 19, in <module>
    with open("not_existing_file.txt", 'r') as text:
FileNotFoundError: [Errno 2] No such file or directory: 'not_existing_file.txt'

Print/Log the full traceback

As others already mentioned, you can catch the whole traceback by using the traceback module:

import traceback
try:
    with open("not_existing_file.txt", 'r') as text:
        pass
except Exception as exception:
    traceback.print_exc()

This will produce the following output:

Traceback (most recent call last):
  File "exception_checks.py", line 19, in <module>
    with open("not_existing_file.txt", 'r') as text:
FileNotFoundError: [Errno 2] No such file or directory: 'not_existing_file.txt'

You can achieve the same by using logging:

try:
    with open("not_existing_file.txt", 'r') as text:
        pass
except Exception as exception:
    logger.error(exception, exc_info=True)

Output:

__main__: 2020-05-27 12:10:47-ERROR- [Errno 2] No such file or directory: 'not_existing_file.txt'
Traceback (most recent call last):
  File "exception_checks.py", line 27, in <module>
    with open("not_existing_file.txt", 'r') as text:
FileNotFoundError: [Errno 2] No such file or directory: 'not_existing_file.txt'

Print/log error name/message only

You might not be interested in the whole traceback, but only in the most important information, such as Exception name and Exception message, use:

try:
    with open("not_existing_file.txt", 'r') as text:
        pass
except Exception as exception:
    print("Exception: {}".format(type(exception).__name__))
    print("Exception message: {}".format(exception))

Output:

Exception: FileNotFoundError
Exception message: [Errno 2] No such file or directory: 'not_existing_file.txt'

There are two primary contenders for python apps on Android

Chaquopy

https://chaquo.com/chaquopy/

This integrates with the Android build system, it provides a Python API for all android features. To quote the site "The complete Android API and user interface toolkit are directly at your disposal."

Beeware (Toga widget toolkit)

https://pybee.org/

This provides a multi target transpiler, supports many targets such as Android and iOS. It uses a generic widget toolkit (toga) that maps to the host interface calls.

Which One?

Both are active projects and their github accounts shows a fair amount of recent activity.

Beeware Toga like all widget libraries is good for getting the basics out to multiple platforms. If you have basic designs, and a desire to expand to other platforms this should work out well for you.

On the other hand, Chaquopy is a much more precise in its mapping of the python API to Android. It also allows you to mix in Java, useful if you want to use existing code from other resources. If you have strict design targets, and predominantly want to target Android this is a much better resource.

Something that your code doesn't account for is displaying multiple errors. As you have noted above it is possible for the user to upload a file >2MB of the wrong type, but your code can only report one of the issues. Try something like:

if(isset($_FILES['uploaded_file'])) {
    $errors     = array();
    $maxsize    = 2097152;
    $acceptable = array(
        'application/pdf',
        'image/jpeg',
        'image/jpg',
        'image/gif',
        'image/png'
    );

    if(($_FILES['uploaded_file']['size'] >= $maxsize) || ($_FILES["uploaded_file"]["size"] == 0)) {
        $errors[] = 'File too large. File must be less than 2 megabytes.';
    }

    if((!in_array($_FILES['uploaded_file']['type'], $acceptable)) && (!empty($_FILES["uploaded_file"]["type"]))) {
        $errors[] = 'Invalid file type. Only PDF, JPG, GIF and PNG types are accepted.';
    }

    if(count($errors) === 0) {
        move_uploaded_file($_FILES['uploaded_file']['tmpname'], '/store/to/location.file');
    } else {
        foreach($errors as $error) {
            echo '<script>alert("'.$error.'");</script>';
        }

        die(); //Ensure no more processing is done
    }
}

Look into the docs for move_uploaded_file() (it's called move not store) for more.

I believe once database rules are written accurately, it will be enough to protect your data. Moreover, there are guidelines that one can follow to structure your database accordingly. For example, making a UID node under users, and putting all under information under it. After that, you will need to implement a simple database rule as below

  "rules": {
    "users": {
      "$uid": {
        ".read": "auth != null && auth.uid == $uid",
        ".write": "auth != null && auth.uid == $uid"
      }
    }
  }
}

No other user will be able to read other users' data, moreover, domain policy will restrict requests coming from other domains. One can read more about it on Firebase Security rules

For iOS 9 beta 3,4 users. Since the option to view profiles is not viewable do the following from Xcode.

1. Open Xcode 7.
2. Go to window, devices.
3. Select your device.
4. Delete all of the profiles loaded on the device.
5. Delete the old app on your device.
6. Clean and rebuild the app to your device.

On iOS 9.1+ n iOS 9.2+ go to Settings -> General -> Device Management -> press the Profile -> Press Trust.

If you are parsing string data from the console or similar, the best way is to use regular expressions. Read more on that here: http://java.sun.com/developer/technicalArticles/releases/1.4regex/

Otherwise, to parse an int from a string, try Integer.parseInt(string). If the string is not a number, you will get an exception. Otherise you can then perform your checks on that value to make sure it is not negative.

String input;
int number;
try
{
    number = Integer.parseInt(input);
    if(number > 0)
    {
        System.out.println("You positive number is " + number);
    }
} catch (NumberFormatException ex)
{
     System.out.println("That is not a positive number!");
}

To get a character-only string, you would probably be better of looping over each character checking for digits, using for instance Character.isLetter(char).

String input
for(int i = 0; i<input.length(); i++)
{
   if(!Character.isLetter(input.charAt(i)))
   {
      System.out.println("This string does not contain only letters!");
      break;
   }
}

Good luck!

Try:

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

<SeekBar 
    android:id="@+id/seekBar1" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:rotation="270" 
    /> 

</RelativeLayout> 

Why not use properly formulated geospatial queries???

Here is the SQL server reference page on the STContains geospatial function:

https://docs.microsoft.com/en-us/sql/t-sql/spatial-geography/stcontains-geography-data-type?view=sql-server-ver15

or if you do not waant to use box and radian conversion , you cna always use the distance function to find the points that you need:

DECLARE @CurrentLocation geography; 
SET @CurrentLocation  = geography::Point(12.822222, 80.222222, 4326)

SELECT * , Round (GeoLocation.STDistance(@CurrentLocation ),0) AS Distance FROM [Landmark]
WHERE GeoLocation.STDistance(@CurrentLocation )<= 2000 -- 2 Km

There should be similar functionality for almost any database out there.

If you have implemented geospatial indexing correctly your searches would be way faster than the approach you are using

A good book on Subversion is Pragmatic Version Control using Subversion where your question is explained, and it gives a lot more information.

base_convert(uniqid('pass', true), 10, 36);

eg. e0m6ngefmj4

EDIT

As I've mentioned in comments, the length means that brute force attacks would work better against it then timing attacks so it's not really relevant to worry about "how secure the random generator was." Security, specifically for this use case, needs to complement usability so the above solution is actually good enough for the required problem.

However, just in case you stumbled upon this answer while searching for a secure random string generator (as I assume some people have based on the responses), for something such as generating tokens, here is how a generator of such codes would look like:

function base64urlEncode($data) {
    return rtrim(strtr(base64_encode($data), '+/', '-_'), '=');
}

function secureId($length = 32) {

    if (function_exists('openssl_random_pseudo_bytes')) {
        $bytes = openssl_random_pseudo_bytes($length);
        return rtrim(strtr(base64_encode($bytes), '+/', '0a'), '=');
    }
    else { // fallback to system bytes

        error_log("Missing support for openssl_random_pseudo_bytes");

        $pr_bits = '';

        $fp = @fopen('/dev/urandom', 'rb');
        if ($fp !== false) {
            $pr_bits .= @fread($fp, $length);
            @fclose($fp);
        }

        if (strlen($pr_bits) < $length) {
            error_log('unable to read /dev/urandom');
            throw new \Exception('unable to read /dev/urandom');
        }

        return base64urlEncode($pr_bits);
    }
}

In Codeigniter This is simple Way to check between two date records ...

$start_date='2016-01-01';
$end_date='2016-01-31';

$this->db->where('date BETWEEN "'. date('Y-m-d', strtotime($start_date)). '" and "'. date('Y-m-d', strtotime($end_date)).'"');

Javascript executor always does the job perfectly:

((JavascriptExecutor) driver).executeScript("scroll(0,300)");

where (0,300) are the horizontal and vertical distances respectively. Put your distances as per your requirements.

If you a perfectionist and like to get the exact distance you like to scroll up to on the first attempt, use this tool, MeasureIt. It's a brilliant firefox add-on.

Although quite old, nevertheless a quick response:

Spring provides UriUtils - with this you can specify how to encoded and which part is it related from an URI, e.g.

encodePathSegment
encodePort
encodeFragment
encodeUriVariables
....

I use them cause we already using Spring, i.e. no additonal library is required!

I figured out a way to telnet to a server and change a file permission. Then FTP the file back to your computer and open it. Hopefully this will answer your questions and also help FTP.

The filepath variable is setup so you always login and cd to the same directory. You can change it to a prompt so the user can enter it manually.

:: This will telnet to the server, change the permissions, 
:: download the file, and then open it from your PC. 

:: Add your username, password, servername, and file path to the file.
:: I have not tested the server name with an IP address.

:: Note - telnetcmd.dat and ftpcmd.dat are temp files used to hold commands

@echo off
SET username=
SET password=
SET servername=
SET filepath=

set /p id="Enter the file name: " %=%

echo user %username%> telnetcmd.dat
echo %password%>> telnetcmd.dat
echo cd %filepath%>> telnetcmd.dat
echo SITE chmod 777 %id%>> telnetcmd.dat
echo exit>> telnetcmd.dat
telnet %servername% < telnetcmd.dat


echo user %username%> ftpcmd.dat
echo %password%>> ftpcmd.dat
echo cd %filepath%>> ftpcmd.dat
echo get %id%>> ftpcmd.dat
echo quit>> ftpcmd.dat

ftp -n -s:ftpcmd.dat %servername%
del ftpcmd.dat
del telnetcmd.dat

Sometimes we may not have access to a Jenkins machine to copy a folder directly into another Jenkins instance. So I wrote a menu driven utility which uses Jenkins REST API calls to install plugins and jobs from one Jenkins instance to another.

For plugin migration:

1. GET request: {SOURCE_JENKINS_SERVER}/pluginManager/api/json?depth=1 will get you the list of plugins installed with their version.

2. You can send a POST request with the following parameters to install these plugins.

   final_url=`{DESTINATION_JENKINS_SERVER}/pluginManager/installNecessaryPlugins`
   
   data=`<jenkins><install plugin="{PLUGIN_NAME}@latest"/></jenkins>` (where, latest will fetch the latest version of the plugin_name)
   
   auth=`(destination_jenkins_username, destination_jenkins_password)`
   
   header=`{crumb_field:crumb_value,"Content-Type":"application/xml”}` (where crumb_field=Jenkins-Crumb and get crumb value using API call {DESTINATION_JENKINS_SERVER}/crumbIssuer/api/json
   

For job migration:

1. You can get the list of jobs installed on {SOURCE_JENKINS_URL} using a REST call, {SOURCE_JENKINS_URL}/view/All/api/json
2. Then you can get each job config.xml file from the jobs on {SOURCE_JENKINS_URL} using the job URL {SOURCE_JENKINS_URL}/job/{JOB_NAME}.
3. Use this config.xml file to POST the content of the XML file on {DESTINATION_JENKINS_URL} and that will create a job on {DESTINATION_JENKINS_URL}.

I have created a menu-driven utility in Python which asks the user to start plugin or Jenkins migration and uses Jenkins REST API calls to do it.

You can refer the JenkinsMigration.docx from this URL jenkinsjenkinsmigrationjenkinsrestapi

Or if you don't know the URL (so as to avoid hardcoding, use the AbsoluteUri

Example ...

        //get the full URL
        Uri myUri = new Uri(Request.Url.AbsoluteUri);
        //get any parameters
        string strStatus = HttpUtility.ParseQueryString(myUri.Query).Get("status");
        string strMsg = HttpUtility.ParseQueryString(myUri.Query).Get("message");
        switch (strStatus.ToUpper())
        {
            case "OK":
                webMessageBox.Show("EMAILS SENT!");
                break;
            case "ER":
                webMessageBox.Show("EMAILS SENT, BUT ... " + strMsg);
                break;
        }

You can also consider to reverse your array and take the first element. That way you don't have to know about the length, but it brings no real benefits and the disadvantage that the reverse operation might take longer with big arrays:

array1.split(",").reverse()[0]

It's easy though, but also modifies the original array in question. That might or might not be a problem.

Reference: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/reverse

Probably you might want to use this though:

array1.split(",").pop()

I think, better way is use HttpPostedFileBase in your controller or API. After this you can simple detect size, type etc.

File properties you can find here:

MVC3 How to check if HttpPostedFileBase is an image

For example ImageApi:

[HttpPost]
[Route("api/image")]  
public ActionResult Index(HttpPostedFileBase file)  
{  
    if (file != null && file.ContentLength > 0)  
        try 
        {  
            string path = Path.Combine(Server.MapPath("~/Images"),  
               Path.GetFileName(file.FileName));

            file.SaveAs(path);  
            ViewBag.Message = "Your message for success";  
        }  
        catch (Exception ex)  
        {  
            ViewBag.Message = "ERROR:" + ex.Message.ToString();  
        }  
    else 
    {  
        ViewBag.Message = "Please select file";  
    }  
    return View();  
}

Hope it help.

$num_words = 101;
$words = array();
$words = explode(" ", $original_string, $num_words);
$shown_string = "";

if(count($words) == 101){
   $words[100] = " ... ";
}

$shown_string = implode(" ", $words);

On Linux it is Ctrl + Shift + I.

On Windows it is Alt + Shift + F. Tested with HTML/CSS/JavaScript and Visual Studio Code 1.18.0.

For other languages, you might need to install a specific language package.

here's working function

function plus_one_day($date){
 $date2 = formatDate4db($date);
 $date1 = str_replace('-', '/', $date2);
 $tomorrow = date('Y-m-d',strtotime($date1 . "+1 days"));
 return $tomorrow; }

There are 3 ways to allow cross domain origin (excluding jsonp):

1) Set the header in the page directly using a templating language like PHP. Keep in mind there can be no HTML before your header or it will fail.

 <?php header("Access-Control-Allow-Origin: http://example.com"); ?>

2) Modify the server configuration file (apache.conf) and add this line. Note that "*" represents allow all. Some systems might also need the credential set. In general allow all access is a security risk and should be avoided:

Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Credentials true

3) To allow multiple domains on Apache web servers add the following to your config file

<IfModule mod_headers.c>
    SetEnvIf Origin "http(s)?://(www\.)?(example.org|example.com)$" AccessControlAllowOrigin=$0$1
    Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
    Header set Access-Control-Allow-Credentials true
</IfModule>

4) For development use only hack your browser and allow unlimited CORS using the Chrome Allow-Control-Allow-Origin extension

5) Disable CORS in Chrome: Quit Chrome completely. Open a terminal and execute the following. Just be cautious you are disabling web security:

open -a Google\ Chrome --args --disable-web-security --user-data-dir

For only date use
date("Y-m-d");

and for only time use
date("H:i:s");

Using jQuery ...

$(document).height() & $(window).height() will return the same values ... the key is to reset body's padding and margin so that you get no scrolling.

<!--

body {
    padding: 0px;
    margin: 0px;
    position: relative;
}

-->

Hope this helps.

Just to give some examples. Let's say you modify the password for an user called 'alex'. You can modify this password in several ways. For instance:

mysql> update* user set password=PASSWORD('test!23') where user='alex'; 
mysql> flush privileges;

Here you used UPDATE. If you use INSERT, UPDATE or DELETE on grant tables directly you need use FLUSH PRIVILEGES in order to reload the grant tables.

Or you can modify the password like this:

mysql> set password for 'alex'@'localhost'= password('test!24');

Here it's not necesary to use "FLUSH PRIVILEGES;" If you modify the grant tables indirectly using account-management statements such as GRANT, REVOKE, SET PASSWORD, or RENAME USER, the server notices these changes and loads the grant tables into memory again immediately.

Lets say we have a script in "c:\script.py" that contain :

result = open("index.html","r")
print(result.read())

Lets say that the index.html file is also in the same directory "c:\index.html" when i execute the script from cmd (or shell)

C:\Users\Amine>python c:\script.py

You will get error:

FileNotFoundError: [Errno 2] No such file or directory: 'index.html'

And that because "index.html" is not in working directory which is "C:\Users\Amine>". so in order to make it work you have to change the working directory

C:\python script.py

'<html><head></head><body></body></html>'

This is why is it preferable to use absolute path.

Yes, you need to close Connection. Otherwise, the database client will typically keep the socket connection and other resources open.

Top down and bottom up DP are two different ways of solving the same problems. Consider a memoized (top down) vs dynamic (bottom up) programming solution to computing fibonacci numbers.

fib_cache = {}

def memo_fib(n):
  global fib_cache
  if n == 0 or n == 1:
     return 1
  if n in fib_cache:
     return fib_cache[n]
  ret = memo_fib(n - 1) + memo_fib(n - 2)
  fib_cache[n] = ret
  return ret

def dp_fib(n):
   partial_answers = [1, 1]
   while len(partial_answers) <= n:
     partial_answers.append(partial_answers[-1] + partial_answers[-2])
   return partial_answers[n]

print memo_fib(5), dp_fib(5)

I personally find memoization much more natural. You can take a recursive function and memoize it by a mechanical process (first lookup answer in cache and return it if possible, otherwise compute it recursively and then before returning, you save the calculation in the cache for future use), whereas doing bottom up dynamic programming requires you to encode an order in which solutions are calculated, such that no "big problem" is computed before the smaller problem that it depends on.

Here's a pair of functions to return the last row and col of a worksheet, based on Reafidy's solution above.

    Function LastRow(ws As Object) As Long

        Dim rLastCell As Object
        On Error GoTo ErrHan
        Set rLastCell = ws.Cells.Find("*", ws.Cells(1, 1), , , xlByRows, _
                                      xlPrevious)
        LastRow = rLastCell.Row

    ErrExit:
        Exit Function

    ErrHan:
        MsgBox "Error " & Err.Number & ": " & Err.Description, _
               vbExclamation, "LastRow()"
        Resume ErrExit

    End Function

    Function LastCol(ws As Object) As Long

        Dim rLastCell As Object
        On Error GoTo ErrHan
        Set rLastCell = ws.Cells.Find("*", ws.Cells(1, 1), , , xlByColumns, _
                                      xlPrevious)
        LastCol = rLastCell.Column

    ErrExit:
        Exit Function

    ErrHan:
        MsgBox "Error " & Err.Number & ": " & Err.Description, _
               vbExclamation, "LastRow()"
        Resume ErrExit

    End Function

I don't like that much solutions based on multiplying text-shadows, it's not really flexible, it may work for a 2 pixels stroke where directions to add are 8, but with just 3 pixels stroke directions became 16, and so on... Not really confortable to manage.

The right tool exists, it's SVG <text> The browsers' support problem worth nothing in this case, 'cause the usage of text-shadow has its own support problem too, filter: progid:DXImageTransform can be used or IE < 10 but often doesn't work as expected.

To me the best solution remains SVG with a fallback in not-stroked text for older browser:

This kind of approuch works on pratically all versions of Chrome and Firefox, Safari since version 3.04, Opera 8, IE 9

Compared to text-shadow whose supports are: Chrome 4.0, FF 3.5, IE 10, Safari 4.0, Opera 9, it results even more compatible.

For some reason, the lib is present while compiling, but missing while running.

My situation is, two versions of one lib conflict.

For example, A depends on B and C, while B depends on D:1.0, C depends on D:1.1, maven may just import D:1.0. If A uses one class which is in D:1.1 but not in D:1.0, a NoClassDefFoundError will be throwed.

If you are in this situation too, you need to resolve the dependency conflict.

Even though I am 3 years late, but to simplify Guffa's example, you don't even need to have the form on the page at all:

$('<form method="post" action="test.asp" target="TheWindow">
       <input type="hidden" name="something" value="something">

Edited:

$('<form method="post" action="test.asp" target="TheWindow">

   </form>').appendTo('body').submit().remove();

Maybe a helpful tip for someone :)

Float: left, display: inline-block will both fail to align the elements horizontally if they exceed the width of the container.

It's important to note that the container should not wrap if the elements MUST display horizontally: white-space: nowrap

Another option is CSVLogger: https://keras.io/callbacks/#csvlogger. It creates a csv file appending the result of each epoch. Even if you interrupt training, you get to see how it evolved.

Here are some more console logging "pro tips":

console.table

var animals = [
    { animal: 'Horse', name: 'Henry', age: 43 },
    { animal: 'Dog', name: 'Fred', age: 13 },
    { animal: 'Cat', name: 'Frodo', age: 18 }
];

console.table(animals);

console.trace

Shows you the call stack for leading up to the console.

You can even customise your consoles to make them stand out

console.todo = function(msg) {
    console.log(‘ % c % s % s % s‘, ‘color: yellow; background - color: black;’, ‘–‘, msg, ‘–‘);
}

console.important = function(msg) {
    console.log(‘ % c % s % s % s’, ‘color: brown; font - weight: bold; text - decoration: underline;’, ‘–‘, msg, ‘–‘);
}

console.todo(“This is something that’ s need to be fixed”);
console.important(‘This is an important message’);

If you really want to level up don't limit your self to the console statement.

Here is a great post on how you can integrate a chrome debugger right into your code editor!

This is the reason why you should whenever possible use strict equality === or strict inequality !==

"100" == 100

true because this only checks value, not the data type

"100" === 100

false this checks value and data type

I think it is better to copy files from your local computer, because if files number or file size is very big, copying process could be interrupted if your current ssh session would be lost (broken pipe or whatever).

If you have configured ssh key to connect to your remote server, you could use the following command:

rsync -avP -e "ssh -i /home/local_user/ssh/key_to_access_remote_server.pem" remote_user@remote_host.ip:/home/remote_user/file.gz /home/local_user/Downloads/

Where v option is --verbose, a option is --archive - archive mode, P option same as --partial - keep partially transferred files, e option is --rsh=COMMAND - specifying the remote shell to use.

rsync man page

if you found an issue when you try to import xgboost (my case it is Windows 10 and anaconda spyder) do the following:

1. Click on the windows icon (start button!)
2. Select and expand the anaconda folder
3. Run the Anaconda Prompt (as Administrator)
4. Type the following command as it is mentioned in https://anaconda.org/anaconda/py-xgboost

conda install -c anaconda py-xgboost

That's all...Good luck.

Ok, let me give the details of code, how to use other module's component.

For example, I have M2 module, M2 module have comp23 component and comp2 component, Now I want to use comp23 and comp2 in app.module, here is how:

this is app.module.ts, see my comment,

 // import this module's ALL component, but not other module's component, only this module
  import { AppComponent } from './app.component';
  import { Comp1Component } from './comp1/comp1.component';

  // import all other module,
 import { SwModule } from './sw/sw.module';
 import { Sw1Module } from './sw1/sw1.module';
 import { M2Module } from './m2/m2.module';

   import { CustomerDashboardModule } from './customer-dashboard/customer-dashboard.module';


 @NgModule({

    // declare only this module's all component, not other module component.  

declarations: [
AppComponent,
Comp1Component,


 ],

 // imports all other module only.
imports: [
BrowserModule,
SwModule,
Sw1Module,
M2Module,
CustomerDashboardModule // add the feature module here
],
 providers: [],
 bootstrap: [AppComponent]
})
export class AppModule { }

this is m2 module:

   import { NgModule } from '@angular/core';
   import { CommonModule } from '@angular/common';

   // must import this module's all component file
   import { Comp2Component } from './comp2/comp2.component';
   import { Comp23Component } from './comp23/comp23.component';

   @NgModule({

   // import all other module here.
     imports: [
       CommonModule
     ],

    // declare only this module's child component. 
     declarations: [Comp2Component, Comp23Component],

   // for other module to use these component, must exports
     exports: [Comp2Component, Comp23Component]
   })
   export class M2Module { }

My commend in code explain what you need to do here.

now in app.component.html, you can use

  <app-comp23></app-comp23>

follow angular doc sample import modul

Since Java 8, we could use streams instead of for loops. Also, it might be apropriate to return an Optional if the enum does not have an instance with such a name.

I have come up with the following three alternatives on how to look up an enum:

private enum Test {
    TEST1, TEST2;

    public Test fromNameOrThrowException(String name) {
        return Arrays.stream(values())
                .filter(e -> e.name().equals(name))
                .findFirst()
                .orElseThrow(() -> new IllegalArgumentException("No enum with name " + name));
    }

    public Test fromNameOrNull(String name) {
        return Arrays.stream(values()).filter(e -> e.name().equals(name)).findFirst().orElse(null);
    }

    public Optional<Test> fromName(String name) {
        return Arrays.stream(values()).filter(e -> e.name().equals(name)).findFirst();
    }
}

In your_controller write this...

public function update_title() 
{   
    $data = array
      (
        'table_id' => $this->input->post('table_id'),
        'table_title' => $this->input->post('table_title')
      );

    $this->load->model('your_model'); // First load the model
    if($this->your_model->update_title($data)) // call the method from the controller
    {
        // update successful...
    }
    else
    {
        // update not successful...
    }

}

While in your_model...

public function update_title($data)
{
   $this->db->set('table_title',$data['title'])
         ->where('table_id',$data['table_id'])
        ->update('your_table');
}

This will works fine...

According to ADO: ActiveX Data Objects, a book by Jason T. Roff, published by O'Reilly Media in 2001 (excellent diagram here), he says precisely what MOZILLA said.

(directly from page 7 of that book)

• ODBC provides access only to relational databases
• OLE DB provides the following features
  • Access to data regardless of its format or location
  • Full access to ODBC data sources and ODBC drivers

So it would seem that OLE DB interacts with SQL-based datasources THRU the ODBC driver layer.

I'm not 100% sure this image is correct. The two connections I'm not certain about are ADO.NET thru ADO C-api, and OLE DB thru ODBC to SQL-based data source (because in this diagram the author doesn't put OLE DB's access thru ODBC, which I believe is a mistake).

Using base-n mini lib, you can do the following:

some_data_t in[] { ... };
constexpr int len = sizeof(in)/sizeof(in[0]);

std::string encoded;
bn::encode_b64(in, in + len, std::back_inserter(encoded));

some_data_t out[len];
bn::decode_b64(encoded.begin(), encoded.end(), out);

The API is generic, iterator-based.

Below find the PHP code to get current UTC(Coordinated Universal Time) time

<?php_x000D_
// Prints the day_x000D_
echo gmdate("l") . "<br>";_x000D_
_x000D_
// Prints the day, date, month, year, time, AM or PM_x000D_
echo gmdate("l jS \of F Y h:i:s A");_x000D_
?>

We apply StandardScalar() on a row basis.

So, for each row in a column (I am assuming that you are working with a Pandas DataFrame):

x_new = (x_original - mean_of_distribution) / std_of_distribution

Few points -

1. It is called Standard Scalar as we are dividing it by the standard deviation of the distribution (distr. of the feature). Similarly, you can guess for MinMaxScalar().

2. The original distribution remains the same after applying StandardScalar(). It is a common misconception that the distribution gets changed to a Normal Distribution. We are just squashing the range into [0, 1].

First of all, the provided long code:

Now, to your question:

how to compare two elements coming from xml as string

In Xpath 1.0 strings can be compared only for equality (or inequality), using the operator = and the function not() together with the operator =.

$str1 = $str2

evaluates to true() exactly when the string $str1 is equal to the string $str2.

not($str1 = $str2)

evaluates to true() exactly when the string $str1 is not equal to the string $str2.

There is also the != operator. It generally should be avoided because it has anomalous behavior whenever one of its operands is a node-set.

Now, the rules for comparing two element nodes are similar:

$el1 = $el2

evaluates to true() exactly when the string value of $el1 is equal to the string value of $el2.

not($el1 = $el2)

evaluates to true() exactly when the string value of $el1 is not equal to the string value of $el2.

However, if one of the operands of = is a node-set, then

 $ns = $str

evaluates to true() exactly when there is at least one node in the node-set $ns1, whose string value is equal to the string $str

$ns1 = $ns2

evaluates to true() exactly when there is at least one node in the node-set $ns1, whose string value is equal to the string value of some node from $ns2

Therefore, the expression:

OU_NAME='OU_ADDR1'

evaluates to true() only when there is at least one element child of the current node that is named OU_NAME and whose string value is the string 'OU_ADDR1'.

This is obviously not what you want!

Most probably you want:

OU_NAME=OU_ADDR1

This expression evaluates to true exactly there is at least one OU_NAME child of the current node and one OU_ADDR1 child of the current node with the same string value.

Finally, in XPath 2.0, strings can be compared also using the value comparison operators lt, le, eq, gt, ge and the inherited from XPath 1.0 general comparison operator =.

Trying to evaluate a value comparison operator when one or both of its arguments is a sequence of more than one item results in error.

Use this in your my.ini under

[mysqldump]
    user=root
    password=anything

There are various ways to achieve this. Here are three.

    Map<String, String> map = new HashMap<String, String>();
    map.put("key1", "value1");
    map.put("key2", "value2");
    map.put("key3", "value3");

    System.out.println("using entrySet and toString");
    for (Entry<String, String> entry : map.entrySet()) {
        System.out.println(entry);
    }
    System.out.println();

    System.out.println("using entrySet and manual string creation");
    for (Entry<String, String> entry : map.entrySet()) {
        System.out.println(entry.getKey() + "=" + entry.getValue());
    }
    System.out.println();

    System.out.println("using keySet");
    for (String key : map.keySet()) {
        System.out.println(key + "=" + map.get(key));
    }
    System.out.println();

Output

using entrySet and toString
key1=value1
key2=value2
key3=value3

using entrySet and manual string creation
key1=value1
key2=value2
key3=value3

using keySet
key1=value1
key2=value2
key3=value3

My site configuration file is example.conf in sites-available folder So you can create a symbolic link as

ln -s /etc/nginx/sites-available/example.conf /etc/nginx/sites-enabled/

You can use the following rule in .htaccess to rewrite a subdomain to a subfolder:

RewriteEngine On

 # If the host is "sub.domain.com"
 RewriteCond %{HTTP_HOST} ^sub.domain.com$ [NC]
 # Then rewrite any request to /folder
 RewriteRule ^((?!folder).*)$ /folder/$1 [NC,L]

Line-by-line explanation:

  RewriteEngine on

The line above tells the server to turn on the engine for rewriting URLs.

  RewriteCond %{HTTP_HOST} ^sub.domain.com$ [NC]

This line is a condition for the RewriteRule where we match against the HTTP host using a regex pattern. The condition says that if the host is sub.domain.com then execute the rule.

 RewriteRule ^((?!folder).*)$ /folder/$1 [NC,L]

The rule matches http://sub.domain.com/foo and internally redirects it to http://sub.domain.com/folder/foo.

Replace sub.domain.com with your subdomain and folder with name of the folder you want to point your subdomain to.

with jQuery:

 $("#playerSource").attr("src", "new_src");

    var audio = $("#player");      

    audio[0].pause();
    audio[0].load();//suspends and restores all audio element

    if (isAutoplay) 
        audio[0].play();

If you're using npm >=1.0, you can use npm link <global-package> to create a local link to a package already installed globally. (Caveat: The OS must support symlinks.)

However, this doesn't come without its problems.

npm link is a development tool. It's awesome for managing packages on your local development box. But deploying with npm link is basically asking for problems, since it makes it super easy to update things without realizing it.

As an alternative, you can install the packages locally as well as globally.

For additional information, see

list(set(listone) | set(listtwo))

The above code, does not preserve order, removes duplicate from each list (but not from the concatenated list)

Well, std::string is a class, const char * is a pointer. Those are two different things. It's easy to get from string to a pointer (since it typically contains one that it can just return), but for the other way, you need to create an object of type std::string.

My recommendation: Functions that take constant strings and don't modify them should always take const char * as an argument. That way, they will always work - with string literals as well as with std::string (via an implicit c_str()).

To create a self signed certificate on Windows 7 with IIS 6...

1. Open IIS

2. Select your server (top level item or your computer's name)

3. Under the IIS section, open "Server Certificates"

4. Click "Create Self-Signed Certificate"

5. Name it "localhost" (or something like that that is not specific)

6. Click "OK"

You can then bind that certificate to your website...

1. Right click on your website and choose "Edit bindings..."

2. Click "Add"

   • Type: https
   • IP address: "All Unassigned"
   • Port: 443
   • SSL certificate: "localhost"

3. Click "OK"

4. Click "Close"

$this->db->where('emailsToCampaigns.campaignId !=' , $campaignId);

This should work (which you have tried)

To debug you might place this code just after you execute your query to see what exact SQL it is producing, this might give you clues, you might add that to the question to allow for further help.

$this->db->get();              // your query executing

echo '<pre>';                  // to preserve formatting
die($this->db->last_query());  // halt execution and print last ran query.

it's as simple as not using a table for markup, as stated by Harmen. You're not displaying data after all, you're collecting data.

I'll take for example the question 23 here: http://accessible.netscouts-ggmbh.eu/en/developer.html#fb1_22_5

On paper, it's good as it is. If you had to display the results, it'd probably be OK.
But you can replace it with ... 4 paragraphs with a label and a select (option's would be the headers of the first line). One paragraph per line, this is far more simple.

It is a very simple and effective utility build in jquery to implement pagination on html table http://tablesorter.com/docs/example-pager.html

Download the plugin from http://tablesorter.com/addons/pager/jquery.tablesorter.pager.js

After adding this plugin add following code in head script

$(document).ready(function() { 
    $("table") 
    .tablesorter({widthFixed: true, widgets: ['zebra']}) 
    .tablesorterPager({container: $("#pager")}); 
}); 

Besides not being a lazy evaluator by evaluating both operands, I think the main characteristics of bitwise operators compare each bytes of operands like in the following example:

int a = 4;
int b = 7;
System.out.println(a & b); // prints 4
//meaning in an 32 bit system
// 00000000 00000000 00000000 00000100
// 00000000 00000000 00000000 00000111
// ===================================
// 00000000 00000000 00000000 00000100
