LIBRARY_PATH is used by gcc before compilation to search directories containing static and shared libraries that need to be linked to your program.

LD_LIBRARY_PATH is used by your program to search directories containing shared libraries after it has been successfully compiled and linked.

EDIT: As pointed below, your libraries can be static or shared. If it is static then the code is copied over into your program and you don't need to search for the library after your program is compiled and linked. If your library is shared then it needs to be dynamically linked to your program and that's when LD_LIBRARY_PATH comes into play.

You can do this in a try and catch block:

try:
    if val is None:
        print("null")
except NameError:
    # throw an exception or do something else

perl -ne 'chomp; printf qq/%s="%s"\n/, split(/\s*:\s*/,$_,2)' file.yml > file.sh

if you do ctrl-z and then type exit it will close background applications.

Ctrl+Q is another good way to kill the application.

You can select it and add to it as normal:

$('head').append('<link />');

One possible way to do this in just one line by using a map, simple I am checking whether a > b if it is true I am assigning c to a otherwise b

c := map[bool]int{true: a, false: b}[a > b]

However, this looks amazing but in some cases it might NOT be the perfect solution because of evaluation order. For example, if I am checking whether an object is not nil get some property out of it, look at the following code snippet which will panic in case of myObj equals nil

type MyStruct struct {
   field1 string
   field2 string 
}

var myObj *MyStruct
myObj = nil 

myField := map[bool]string{true: myObj.field1, false: "empty!"}[myObj != nil}

Because map will be created and built first before evaluating the condition so in case of myObj = nil this will simply panic.

Not to forget to mention that you can still do the conditions in just one simple line, check the following:

var c int
...
if a > b { c = a } else { c = b}

I found another solution for new Sonar versions where JaCoCo's binary report format (*.exec) was deprecated and the preferred format is XML (SonarJava 5.12 and higher). The solution is very simple and similar to the previous solution with *.exec reports in parent directory from this topic: https://stackoverflow.com/a/15535970/4448263.

Assuming that our project structure is:

moduleC - aggregate project's pom
  |- moduleA - some classes without tests
  |- moduleB - some classes depending from moduleA and tests for classes in both modules: moduleA and moduleB

You need following maven build plugin configuration in aggregate project's pom:

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.8.5</version>
    <executions>
        <execution>
            <id>prepare-and-report</id>
            <goals>
                <goal>prepare-agent</goal>
                <goal>report</goal>
            </goals>
        </execution>
        <execution>
            <id>report-aggregate</id>
            <phase>verify</phase>
            <goals>
                <goal>report-aggregate</goal>
            </goals>
            <configuration>
                <outputDirectory>${project.basedir}/../target/site/jacoco-aggregate</outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

Then build project with maven:

mvn clean verify

And for Sonar you should set property in administration GUI:

sonar.coverage.jacoco.xmlReportPaths=target/site/jacoco/jacoco.xml,../target/site/jacoco-aggregate/jacoco.xml

or using command line:

mvn sonar:sonar -Dsonar.coverage.jacoco.xmlReportPaths=target/site/jacoco/jacoco.xml,../target/site/jacoco-aggregate/jacoco.xml

Description

This creates binary reports for each module in default directories: target/jacoco.exec. Then creates XML reports for each module in default directories: target/site/jacoco/jacoco.xml. Then creates an aggregate report for each module in custom directory ${project.basedir}/../target/site/jacoco-aggregate/ that is relative to parent directory for each module. For moduleA and moduleB this will be common path moduleC/target/site/jacoco-aggregate/.

As moduleB depends on moduleA, moduleB will be built last and its report will be used as an aggregate coverage report in Sonar for both modules A and B.

In addition to the aggregate report, we need a normal module report as JaCoCo aggregate reports contain coverage data only for dependencies.

Together, these two types of reports providing full coverage data for Sonar.

There is one little restriction: you should be able to write a report in the project's parent directory (should have permission). Or you can set property jacoco.skip=true in root project's pom.xml (moduleC) and jacoco.skip=false in modules with classes and tests (moduleA and moduleB).

You can also use -match against a Regular expression. Ex:

if ($dbUserName -match ".{8}" )
{
    Write-Output " Please enter more than 8 characters "
    $dbUserName=read-host " Re-enter database user name"
}

Also if you're like me and like your curly braces to be in the same horizontal position for your code blocks, you can put that on a new line, since it's expecting a code block it will look on next line. In some commands where the first curly brace has to be in-line with your command, you can use a grave accent marker (`) to tell powershell to treat the next line as a continuation.

function calcSize($size,$accuracy=2) {
    $units = array('b','Kb','Mb','Gb');
    foreach($units as $n=>$u) {
        $div = pow(1024,$n);
        if($size > $div) $output = number_format($size/$div,$accuracy).$u;
    }
    return $output;
}

I don't know of a way to force Chrome to not clear the Network debugger, but this might accomplish what you're looking for:

1. Open the js console
2. window.addEventListener("beforeunload", function() { debugger; }, false)

This will pause chrome before loading the new page by hitting a breakpoint.

An easier solution has been outlined here: Validate select box

Make the value be empty and add the required attribute

<select id="select" class="required">
<option value="">Choose an option</option> 
<option value="option1">Option1</option>
<option value="option2">Option2</option>
<option value="option3">Option3</option>
</select>

The right mental model for using mutexes: The mutex protects an invariant.

Why are you sure that this is really right mental model for using mutexes? I think right model is protecting data but not invariants.

The problem of protecting invariants presents even in single-threaded applications and has nothing common with multi-threading and mutexes.

Furthermore, if you need to protect invariants, you still may use binary semaphore wich is never recursive.

In PHP5, you should use the Document Object Model class instead. Example:

$domDoc = new DOMDocument;
$rootElt = $domDoc->createElement('root');
$rootNode = $domDoc->appendChild($rootElt);

$subElt = $domDoc->createElement('foo');
$attr = $domDoc->createAttribute('ah');
$attrVal = $domDoc->createTextNode('OK');
$attr->appendChild($attrVal);
$subElt->appendChild($attr);
$subNode = $rootNode->appendChild($subElt);

$textNode = $domDoc->createTextNode('Wow, it works!');
$subNode->appendChild($textNode);

echo htmlentities($domDoc->saveXML());

Solution

import UIKit

extension UIView {

    func removeConstraints() { removeConstraints(constraints) }
    func deactivateAllConstraints() { NSLayoutConstraint.deactivate(getAllConstraints()) }
    func getAllSubviews() -> [UIView] { return UIView.getAllSubviews(view: self) }

Download the appropriate APR based tomcat native library for your operating system so that Apache tomcat server can take some advantage of the feature of your OS which is not included by default in tomcat. For windows it will be a .dll file.

I too got the warning while starting the server and you don't have to worry about this if you are testing or developing. This is meant to be on production purposes. After putting the tcnative-1.dll file inside the bin folder of Apache Tomcat 7 following are the output in the stderr file,

My use case is that I'm on a metered account. Data transfer is limited on weekdays, Mon - Fri, from 6am - 6pm. I am using bandwidth limiting, but somehow, data still slips through, about 1GB per day!

I strongly suspected it's sickrage or sickbeard, doing a high amount of searches. My download machine is called "download." The following was my solution, using the above,for starting, and stopping the download VM, using KVM:

# Stop download Mon-Fri, 6am
0 6 * * 1,2,3,4,5 root          virsh shutdown download
# Start download Mon-Fri, 6pm
0 18 * * 1,2,3,4,5 root         virsh start download

I think this is correct, and hope it helps someone else too.

The git blame command annotates lines with information from the revision which last modified the line, and... with Git 2.22 (Q2 2019), will do so faster, because of a performance fix around "git blame", especially in a linear history (which is the norm we should optimize for).

See commit f892014 (02 Apr 2019) by David Kastrup (fedelibre). ^{(Merged by Junio C Hamano -- gitster -- in commit 4d8c4da, 25 Apr 2019)}

blame.c: don't drop origin blobs as eagerly

When a parent blob already has chunks queued up for blaming, dropping the blob at the end of one blame step will cause it to get reloaded right away, doubling the amount of I/O and unpacking when processing a linear history.

Keeping such parent blobs in memory seems like a reasonable optimization that should incur additional memory pressure mostly when processing the merges from old branches.

pyHook might help. http://sourceforge.net/apps/mediawiki/pyhook/index.php?title=PyHook_Tutorial#tocpyHook%5FTutorial4

See keyboard hooks; this is more generalized-- if you want specific keyboard interactions and not just using KeyboardInterrupt.

Also, in general (depending on your use) I think having the Ctrl-C option still available to kill your script makes sense.

See also previous question: Detect in python which keys are pressed

If one want to make executable hello.py

first find the path where python is in your os with : which python

it usually resides under "/usr/bin/python" folder.

at the very first line of hello.py one should add : #!/usr/bin/python

then through linux command chmod

one should just make it executable like : chmod +x hello.py

and execute with ./hello.py

print type(someObject).__name__

If that doesn't suit you, use this:

print some_instance.__class__.__name__

Example:

class A:
    pass
print type(A())
# prints <type 'instance'>
print A().__class__.__name__
# prints A

Also, it seems there are differences with type() when using new-style classes vs old-style (that is, inheritance from object). For a new-style class, type(someObject).__name__ returns the name, and for old-style classes it returns instance.

OK,

One of the more difficult concepts to grasp about Excel VSTO programming is that you don't refer to cells like an array, Worksheet[0][0] won't give you cell A1, it will error out on you. Even when you type into A1 when Excel is open, you are actually entering data into Range A1. Therefore you refer to cells as Named Ranges. Here's an example:

Excel.Worksheet sheet = workbook.Sheets["Sheet1"] as Excel.Worksheet; 
Excel.Range range = sheet.get_Range("A1", Missing.Value)

You can now literally type:

range.Text // this will give you the text the user sees
range.Value2 // this will give you the actual value stored by Excel (without rounding)

If you want to do something like this:

Excel.Range range = sheet.get_Range("A1:A5", Missing.Value)

if (range1 != null)
     foreach (Excel.Range r in range1)
     {
         string user = r.Text
         string value = r.Value2

     }

There might be a better way, but this has worked for me.

The reason you need to use Value2 and not Value is because the Value property is a parametrized and C# doesn't support them yet.

As for the cleanup code, i will post that when i get to work tomorrow, i don't have the code with me, but it's very boilerplate. You just close and release the objects in the reverse order you created them. You can't use a Using() block because the Excel.Application or Excel.Workbook doesn't implement IDisposable, and if you don't clean-up, you will be left with a hanging Excel objects in memory.

Note:

• If you don't set the Visibility property Excel doesn't display, which can be disconcerting to your users, but if you want to just rip the data out, that is probably good enough
• You could OleDb, that will work too.

I hope that gets you started, let me know if you need further clarification. I'll post a complete

here is a complete sample:

using System;
using System.IO;
using System.Reflection;
using NUnit.Framework;
using ExcelTools = Ms.Office;
using Excel = Microsoft.Office.Interop.Excel;

namespace Tests
{
    [TestFixture]
    public class ExcelSingle
    {
        [Test]
        public void ProcessWorkbook()
        {
            string file = @"C:\Users\Chris\Desktop\TestSheet.xls";
            Console.WriteLine(file);

            Excel.Application excel = null;
            Excel.Workbook wkb = null;

            try
            {
                excel = new Excel.Application();

                wkb = ExcelTools.OfficeUtil.OpenBook(excel, file);

                Excel.Worksheet sheet = wkb.Sheets["Data"] as Excel.Worksheet;

                Excel.Range range = null;

                if (sheet != null)
                    range = sheet.get_Range("A1", Missing.Value);

                string A1 = String.Empty;

                if( range != null )
                    A1 = range.Text.ToString();

                Console.WriteLine("A1 value: {0}", A1);

            }
            catch(Exception ex)
            {
                //if you need to handle stuff
                Console.WriteLine(ex.Message);
            }
            finally
            {
                if (wkb != null)
                    ExcelTools.OfficeUtil.ReleaseRCM(wkb);

                if (excel != null)
                    ExcelTools.OfficeUtil.ReleaseRCM(excel);
            }
        }
    }
}

I'll post the functions from ExcelTools tomorrow, I don't have that code with me either.

Edit: As promised, here are the Functions from ExcelTools you might need.

public static Excel.Workbook OpenBook(Excel.Application excelInstance, string fileName, bool readOnly, bool editable,
        bool updateLinks) {
        Excel.Workbook book = excelInstance.Workbooks.Open(
            fileName, updateLinks, readOnly,
            Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, editable, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, Type.Missing);
        return book;
    }

public static void ReleaseRCM(object o) {
        try {
            System.Runtime.InteropServices.Marshal.ReleaseComObject(o);
        } catch {
        } finally {
            o = null;
        }
    }

To be frank, this stuff is much easier if you use VB.NET. It's in C# because I didn't write it. VB.NET does option parameters well, C# does not, hence the Type.Missing. Once you typed Type.Missing twice in a row, you run screaming from the room!

As for you question, you can try to following:

http://msdn.microsoft.com/en-us/library/microsoft.office.interop.excel.range.find(VS.80).aspx

I will post an example when I get back from my meeting... cheers

Edit: Here is an example

range = sheet.Cells.Find("Value to Find",
                                                 Type.Missing,
                                                 Type.Missing,
                                                 Type.Missing,
                                                 Type.Missing,
                                                 Excel.XlSearchDirection.xlNext,
                                                 Type.Missing,
                                                 Type.Missing, Type.Missing);

range.Text; //give you the value found

Here is another example inspired by this site:

 range = sheet.Cells.Find("Value to find", Type.Missing, Type.Missing,Excel.XlLookAt.xlWhole,Excel.XlSearchOrder.xlByColumns,Excel.XlSearchDirection.xlNext,false, false, Type.Missing);

It helps to understand the parameters.

P.S. I'm one of those weird people who enjoys learning COM automation. All this code steamed from a tool I wrote for work which required me to process over 1000+ spreadsheets from the lab each Monday.

You can change project facet from Project --> Properties --> Project Facet --> Java --> {required JDK version}

Try this code ...

    Integer perc = 5;
    BigDecimal spread = BigDecimal.ZERO; 
    BigDecimal perc = spread.setScale(perc,BigDecimal.ROUND_HALF_UP);
    System.out.println(perc);

Result: 0.00000

Try:

select
     id,
     StartDate,
CASE WHEN StartDate IS NULL
    THEN 'Awaiting'
    ELSE 'Approved' END AS StartDateStatus
FROM myTable

You code would have been doing a When StartDate = NULL, I think.

NULL is never equal to NULL (as NULL is the absence of a value). NULL is also never not equal to NULL. The syntax noted above is ANSI SQL standard and the converse would be StartDate IS NOT NULL.

You can run the following:

SELECT CASE WHEN (NULL = NULL) THEN 1 ELSE 0 END AS EqualityCheck,
CASE WHEN (NULL <> NULL) THEN 1 ELSE 0 END AS InEqualityCheck,
CASE WHEN (NULL IS NULL) THEN 1 ELSE 0 END AS NullComparison

And this returns:

EqualityCheck = 0
InEqualityCheck = 0
NullComparison = 1

For completeness, in SQL Server you can:

SET ANSI_NULLS OFF;

Which would result in your equals comparisons working differently:

SET ANSI_NULLS OFF

SELECT CASE WHEN (NULL = NULL) THEN 1 ELSE 0 END AS EqualityCheck,
CASE WHEN (NULL <> NULL) THEN 1 ELSE 0 END AS InEqualityCheck,
CASE WHEN (NULL IS NULL) THEN 1 ELSE 0 END AS NullComparison

Which returns:

EqualityCheck = 1
InEqualityCheck = 0
NullComparison = 1

But I would highly recommend against doing this. People subsequently maintaining your code might be compelled to hunt you down and hurt you...

Also, it will no longer work in upcoming versions of SQL server:

On Mac OS X using Visual Studio Code version 1.34.0 (1.34.0) I had to do the following to get Visual Studio Code to recognise the virtual environments:

Location of my virtual environment (named ml_venv):

/Users/auser/.pyvenv/ml_venv

auser@HOST:~/.pyvenv$ tree -d -L 2
.
+-- ml_venv
    +-- bin
    +-- include
    +-- lib

I added the following entry in Settings.json: "python.venvPath": "/Users/auser/.pyvenv"

I restarted the IDE, and now I could see the interpreter from my virtual environment:

In my case I just wanted a line break after each dd element.

Eg, I wanted to style this:

<dl class="p">
  <dt>Created</dt> <dd><time>2021-02-03T14:23:43.073Z</time></dd>
  <dt>Updated</dt> <dd><time>2021-02-03T14:44:15.929Z</time></dd>
</p>

like the default style of this:

<p>
  <span>Created</span> <time>2021-02-03T14:23:43.073Z</time><br>
  <span>Updated</span> <time>2021-02-03T14:44:15.929Z</time>
</p>

which just looks like this:

Created 2021-02-03T14:23:43.073Z
Updated 2021-02-03T14:44:15.929Z

To do that I used this CSS:

dl.p > dt {
  display: inline;
}

dl.p > dd {
  display: inline;
  margin: 0;
}

dl.p > dd::after {
  content: "\A";
  white-space: pre;
}

Or you could use this CSS:

dl.p > dt {
  float: left;
  margin-inline-end: 0.26em;
}

dl.p > dd {
  margin: 0;
}

I also added a colon after each dt element with this CSS:

dl.p > dt::after {
  content: ":";
}

Layers are conceptual entities, and are used to separate the functionality of software system from a logical point of view; when you implement the system you organize these layers using different methods; in this condition we refer to them not as layers but as tiers.

getElementById

Return Value: An Element Object, representing an element with the specified ID. Returns null if no elements with the specified ID exists see: https://www.w3schools.com/jsref/met_document_getelementbyid.asp

Truthy vs Falsy

In JavaScript, a truthy value is a value that is considered true when evaluated in a Boolean context. All values are truthy unless they are defined as falsy (i.e., except for false, 0, "", null, undefined, and NaN). see: https://developer.mozilla.org/en-US/docs/Glossary/Truthy

When the dom element is not found in the document it will return null. null is a Falsy and can be used as boolean expression in the if statement.

var myElement = document.getElementById("myElement");
if(myElement){
  // Element exists
}

Often used with/as a part of OOAD and business modeling. The definition by Neil is correct, but it is basically identical to MVC, but just abstracted for the business. The "Good summary" is well done so I will not copy it here as it is not my work, more detailed but inline with Neil's bullet points.

All the other answers use variables and SET operations. Here's a way to do it within a select statement. Just drop this in as a column in your existing select.

    (SELECT 
        '<table style=''font-family:"Verdana"; font-size: 10pt''>'
                    + '<tr bgcolor="#9DBED4"><th>col1</th><th>col2</th><th>col3</th><th>col4</th><th>col5</th></tr>'
                    + replace( replace( body, '&lt;', '<' ), '&gt;', '>' )
                    + '</table>'
    FROM
    (
        select cast( (
            select td = cast(col1 as varchar(5)) + '</td><td align="right">' + col2 + '</td><td>' + col3 + '</td><td align="right">' + cast(col4 as varchar(5)) + '</td><td align="right">' + cast(col5 as varchar(5)) + '</td>'
            from (
                    select col1  = col1,
                            col2 = col2,
                            col3 = col3,
                            col4 = col4,
                            col5 = col5
                    from m_LineLevel as onml
                    where onml.pkey = oni.pkey
                    ) as d

400 Bad request Error will be thrown due to incorrect authentication entries.

1. Check if your API URL is correct or wrong. Don't append or prepend spaces.
2. Verify that your username and password are valid. Please check any spelling mistake(s) while entering.

Note: Mostly due to Incorrect authentication entries due to spell changes will occur 400 Bad request.

var array = new Array(); // or the shortcut: = []
array.push ( {"cool":"34.33","also cool":"45454"} );
array.push (  {"cool":"34.39","also cool":"45459"} );

Your variable is a javascript object {} not an array [].

You could do:

var o = {}; // or the longer form: = new Object()
o.SomeNewProperty = "something";
o["SomeNewProperty"] = "something";

and

var o = { SomeNewProperty: "something" };
var o2 = { "SomeNewProperty": "something" };

Later, you add those objects to your array: array.push (o, o2);

Also JSON is simply a string representation of a javascript object, thus:

var json = '{"cool":"34.33","alsocool":"45454"}'; // is JSON
var o = JSON.parse(json); // is a javascript object
json = JSON.stringify(o); // is JSON again

To unset the $_POST variable, redeclare it as an empty array:

$_POST = array();

I adopted a SQL 2012 database where I was not a sysadmin but was an administrator on the machine. I used SSMS with "Run as Administrator", added my NT account as a SQL login and set the server role to sysadmin. No problem.

You have a selector ul on line 252 which is setting list-style: square outside none (a square bullet). You'll have to change it to list-style: none or just remove the line.

If you only want to remove the bullets from that specific instance, you can use the specific selector for that list and its items as follows:

ul#groups-list.items-list { list-style: none }

from d1 in DealerContrac join d2 in DealerContrac on d1.dealearid equals d2.dealerid select new {dealercontract.*}

I have used this before and I think in order to make sure credential persist and in a best secure way is

1. you can write them to the app config file using the ConfigurationManager class
2. securing the password using the SecureString class
3. then encrypting it using tools in the Cryptography namespace.

Questioner here, I have got to say getting a tool that does not take 5 minutes to answer any click makes it a lot easier to find potential memory leaks.

Since people are suggesting several tools ( I only tried visual wm since I got that in the JDK and JProbe trial ) I though I should suggest a free / open source tool built on the Eclipse platform, the Memory Analyzer (sometimes referenced as the SAP memory analyzer) available on http://www.eclipse.org/mat/ .

What is really cool about this tool is that it indexed the heap dump when I first opened it which allowed it to show data like retained heap without waiting 5 minutes for each object (pretty much all operations were tons faster than the other tools I tried).

When you open the dump, the first screen shows you a pie chart with the biggest objects (counting retained heap) and one can quickly navigate down to the objects that are to big for comfort. It also has a Find likely leak suspects which I reccon can come in handy, but since the navigation was enough for me I did not really get into it.

Provided .wrapper is inside .item, and provided you're either not in IE 6 or .item is an a tag, the CSS you have should work just fine. Do you have evidence to suggest it isn't?

EDIT:

CSS alone can't affect something not contained within it. To make this happen, format your menu like so:

<ul class="menu">
    <li class="menuitem">
        <a href="destination">menu text</a>
        <ul class="menu">
            <li class="menuitem">
                <a href="destination">part of pull-out menu</a>
... etc ...

and your CSS like this:

.menu .menu {
    display: none;
}

.menu .menuitem:hover .menu {
    display: block;
    float: left;
    // likely need to set top & left
}

You can try using the below code

NSString *fileName = @"Demo.pdf";
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *pdfFileName = [documentsDirectory stringByAppendingPathComponent:fileName];
    NSLog(@"File path%@",pdfFileName);

The answer is definitely implementation-specific. To find out definitively for your platform/compiler, just add this output somewhere in your code:

printf ("sizeof time_t is: %d\n", sizeof(time_t));

If the answer is 4 (32 bits) and your data is meant to go beyond 2038, then you have 25 years to migrate your code.

Your data will be fine if you store your data as a string, even if it's something simple like:

FILE *stream = [stream file pointer that you've opened correctly];
fprintf (stream, "%d\n", (int)time_t);

Then just read it back the same way (fread, fscanf, etc. into an int), and you have your epoch offset time. A similar workaround exists in .Net. I pass 64-bit epoch numbers between Win and Linux systems with no problem (over a communications channel). That brings up byte-ordering issues, but that's another subject.

To answer paxdiablo's query, I'd say that it printed "19100" because the program was written this way (and I admit I did this myself in the '80's):

time_t now;
struct tm local_date_time;
now = time(NULL);
// convert, then copy internal object to our object
memcpy (&local_date_time, localtime(&now), sizeof(local_date_time));
printf ("Year is: 19%02d\n", local_date_time.tm_year);

The printf statement prints the fixed string "Year is: 19" followed by a zero-padded string with the "years since 1900" (definition of tm->tm_year). In 2000, that value is 100, obviously. "%02d" pads with two zeros but does not truncate if longer than two digits.

The correct way is (change to last line only):

printf ("Year is: %d\n", local_date_time.tm_year + 1900);

New question: What's the rationale for that thinking?

This variant allows getting desired precision:

>>> a = 1234.5678
>>> (lambda x, y: (int(x), int(x*y) % y/y))(a, 1e0)
(1234, 0.0)
>>> (lambda x, y: (int(x), int(x*y) % y/y))(a, 1e1)
(1234, 0.5)
>>> (lambda x, y: (int(x), int(x*y) % y/y))(a, 1e15)
(1234, 0.5678)

Best solution would be to use writing-mode writing-mode: vertical-rl; https://developer.mozilla.org/en-US/docs/Web/CSS/writing-mode

It defines whether lines of text are laid out horizontally or vertically and the direction in which blocks progress.

It has good browser support, but will not work on IE8 (if you care about IE) http://caniuse.com/#feat=css-writing-mode

Going further on the answer of Slaks, if one or more lists in your dictionary is null, a System.NullReferenceException will be thrown when calling ToList(), play safe:

List<MyType> allItems = myDico.Values.Where(x => x != null).SelectMany(x => x).ToList();

The solution I came up with was as follows:

1. Create the SQL query in your favorite query dev tool
2. In Crystal Reports, within the main report, create parameter to pass to the subreport
3. Create sub report, using the 'Add Command' option in the 'Data' portion of the 'Report Creation Wizard' and the SQL query from #1.

4. Once the subreport is added to the main report, right click on the subreport, choose 'Change Subreport Links...', select the link field, and uncheck 'Select data in subreport based on field:'

   NOTE: You may have to initially add the parameter with the 'Select data in subreport based on field:' checked, then go back to 'Change Subreport Links ' and uncheck it after the subreport has been created.

5. In the subreport, click the 'Report' menu, 'Select Expert', use the 'Formula Editor', set the SQL column from #1 either equal to or like the parameter(s) selected in #4.

                   (Subreport SQL Column)  (Parameter from Main Report)
           Example:  {Command.Project} like {?Pm-?Proj_Name}
   

What is count1 set to? If it is not set, it looks like the empty string - and that would lead to an invalid expression. Which shell are you using?

In Bash 3.x on MacOS X 10.7.1:

$ count7=0
$ count7=$(($count7 + $count1))
-sh: 0 + : syntax error: operand expected (error token is " ")
$ count1=2
$ count7=$(($count7 + $count1))
$ echo $count7
2
$

You could also use ${count1:-0} to add 0 if $count1 is unset.

Along the lines of Guava, Apache Commons Lang has ExceptionUtils.getFullStackTrace in org.apache.commons.lang.exception. From a prior answer on StackOverflow.

This answer doesn't help for SQL databases where SharePoint is connected. db_securityadmin is required for the configuration databases. In order to add db_securityadmin, you will need to change the owner of the database to an administrative account. You can use that account just for dbo roles.

This is how it can be fixed easily through Storyboard (iOS 11 and Xcode 9.1):

This is easily done by adding a ScriptIgnore attribute to the Gender property, causing it to not be serialised, and adding a GenderString property which does get serialised:

class Person
{
    int Age { get; set; }

    [ScriptIgnore]
    Gender Gender { get; set; }

    string GenderString { get { return Gender.ToString(); } }
}

Could you provide a whole makefile? But right now I can tell - you should check that "install" target already exists. So, check Makefile whether it contains a

install: (anything there)

line. If not, there is no such target and so make has right. Probably you should use just "make" command to compile and then use it as is or install yourself, manually.

Install is not any standard of make, it is just a common target, that could exists, but not necessary.

I'm running OSX. The solutions suggested didn't work for me. I'm using OSX Yosemite. I restarted my Mac then I uninstalled VirtualBox by launching the uninstall script (which is shown when you launch the dmg of VirtualBox) then reinstalled it. I also uninstalled and reinstalled Genymotion. Now everything is working smooth.

Add a reference to System.Management for your project, then try something like this:

namespace ConsoleApplication1
{
  using System;
  using System.Collections.Generic;
  using System.Management; // need to add System.Management to your project references.

  class Program
  {
    static void Main(string[] args)
    {
      var usbDevices = GetUSBDevices();

      foreach (var usbDevice in usbDevices)
      {
        Console.WriteLine("Device ID: {0}, PNP Device ID: {1}, Description: {2}",
            usbDevice.DeviceID, usbDevice.PnpDeviceID, usbDevice.Description);
      }

      Console.Read();
    }

    static List<USBDeviceInfo> GetUSBDevices()
    {
      List<USBDeviceInfo> devices = new List<USBDeviceInfo>();

      ManagementObjectCollection collection;
      using (var searcher = new ManagementObjectSearcher(@"Select * From Win32_USBHub"))
        collection = searcher.Get();      

      foreach (var device in collection)
      {
        devices.Add(new USBDeviceInfo(
        (string)device.GetPropertyValue("DeviceID"),
        (string)device.GetPropertyValue("PNPDeviceID"),
        (string)device.GetPropertyValue("Description")
        ));
      }

      collection.Dispose();
      return devices;
    }
  }

  class USBDeviceInfo
  {
    public USBDeviceInfo(string deviceID, string pnpDeviceID, string description)
    {
      this.DeviceID = deviceID;
      this.PnpDeviceID = pnpDeviceID;
      this.Description = description;
    }
    public string DeviceID { get; private set; }
    public string PnpDeviceID { get; private set; }
    public string Description { get; private set; }
  }
}

For everybody that falls off google, in here, this is the fix for VSCode 1.40 (2019):

Open the global settings.json: File > Preferences > Settings

Then select the tab 'User', open the section 'Extensions', click on 'C/C++'. Then scroll the right panel till you find a 'Edit in settings.json' button.

Last, you add the "C_Cpp.default.includePath" section. The code provided there is from my own system (Windows 7). You can use it as a base for your own libraries paths. (Remember to change the YOUR USERNAME to your correct system (my case windows) username)
(edit info: There is a problem with the recursion of my approach. VSCode doesn't like multiple definitions for the same thing. I solved it with "C_Cpp.intelliSenseEngine": "Tag Parser" )

the code before line 7, on the settings.json has nothing to do with arduino or includePath. You may not copy that...

JSON section to add to settings.json:

"C_Cpp.default.includePath": [
        "C:/Program Files (x86)/Arduino/libraries/**",
        "C:/Program Files (x86)/Arduino/hardware/arduino/avr/cores/arduino/**",
        "C:/Program Files (x86)/Arduino/hardware/tools/avr/avr/include/**",
        "C:/Program Files (x86)/Arduino/hardware/tools/avr/lib/gcc/avr/5.4.0/include/**",
        "C:/Program Files (x86)/Arduino/hardware/arduino/avr/variants/standard/**",
        "C:/Users/<YOUR USERNAME>/.platformio/packages/framework-arduinoavr/**",
        "C:/Users/<YOUR USERNAME>/Documents/Arduino/libraries/**",
        "{$workspaceFolder}/libraries/**",
        "{$workspaceFolder}/**"
    ],
"C_Cpp.intelliSenseEngine": "Tag Parser"

You can remove the whitespaces via css using white-space so you can keep your pretty HTML layout. Don't forget to set the white-space back to normal again if you want your text to wrap inside the columns.

Tested in IE9, Chrome 18, FF 12

.container { white-space: nowrap; }
.column { display: inline-block; width: 50%; white-space: normal; }

<div class="container">
  <div class="column">text that can wrap</div>
  <div class="column">text that can wrap</div>
</div>

You can use an infinite loop to achieve this:

while true
do
  read -p "Enter password" passwd
  case "$passwd" in
    <some good condition> ) break;;
  esac
done

I've been dealing with 01 - which is a numeric.

string(number($v)) != string($v) makes the segregation

There are three levels at which a newline could be inserted in a variable.
Well ..., technically four, but the first two are just two ways to write the newline in code.

1.1. At creation.

The most basic is to create the variable with the newlines already.
We write the variable value in code with the newlines already inserted.

$ var="a
> b
> c"
$ echo "$var"
a
b
c

Or, inside an script code:

var="a
b
c"

Yes, that means writing Enter where needed in the code.

1.2. Create using shell quoting.

The sequence $' is an special shell expansion in bash and zsh.

var=$'a\nb\nc'

The line is parsed by the shell and expanded to « var="anewlinebnewlinec" », which is exactly what we want the variable var to be.
That will not work on older shells.

2. Using shell expansions.

It is basically a command expansion with several commands:

1. echo -e

   var="$( echo -e "a\nb\nc" )"
   

2. The bash and zsh printf '%b'

   var="$( printf '%b' "a\nb\nc" )"
   

3. The bash printf -v

   printf -v var '%b' "a\nb\nc"
   

4. Plain simple printf (works on most shells):

   var="$( printf 'a\nb\nc' )"
   

3. Using shell execution.

All the commands listed in the second option could be used to expand the value of a var, if that var contains special characters.
So, all we need to do is get those values inside the var and execute some command to show:

var="a\nb\nc"                 # var will contain the characters \n not a newline.

echo -e "$var"                # use echo.
printf "%b" "$var"            # use bash %b in printf.
printf "$var"                 # use plain printf.

Note that printf is somewhat unsafe if var value is controlled by an attacker.

Leonbloy's answer is quite complete. I would only add the special case in which one needs to get the last inserted value from within a PL/pgSQL function where OPTION 3 doesn't fit exactly.

For example, if we have the following tables:

CREATE TABLE person(
   id serial,
   lastname character varying (50),
   firstname character varying (50),
   CONSTRAINT person_pk PRIMARY KEY (id)
);

CREATE TABLE client (
    id integer,
   CONSTRAINT client_pk PRIMARY KEY (id),
   CONSTRAINT fk_client_person FOREIGN KEY (id)
       REFERENCES person (id) MATCH SIMPLE
);

If we need to insert a client record we must refer to a person record. But let's say we want to devise a PL/pgSQL function that inserts a new record into client but also takes care of inserting the new person record. For that, we must use a slight variation of leonbloy's OPTION 3:

INSERT INTO person(lastname, firstname) 
VALUES (lastn, firstn) 
RETURNING id INTO [new_variable];

Note that there are two INTO clauses. Therefore, the PL/pgSQL function would be defined like:

CREATE OR REPLACE FUNCTION new_client(lastn character varying, firstn character varying)
  RETURNS integer AS
$BODY$
DECLARE
   v_id integer;
BEGIN
   -- Inserts the new person record and retrieves the last inserted id
   INSERT INTO person(lastname, firstname)
   VALUES (lastn, firstn)
   RETURNING id INTO v_id;

   -- Inserts the new client and references the inserted person
   INSERT INTO client(id) VALUES (v_id);

   -- Return the new id so we can use it in a select clause or return the new id into the user application
    RETURN v_id;
END;
$BODY$
  LANGUAGE plpgsql VOLATILE;

Now we can insert the new data using:

SELECT new_client('Smith', 'John');

or

SELECT * FROM new_client('Smith', 'John');

And we get the newly created id.

new_client
integer

Apparently Chrome and Safari are wrong: onchange should only be triggered when the user releases the mouse. To get continuous updates, you should use the oninput event, which will capture live updates in Firefox, Safari and Chrome, both from the mouse and the keyboard.

However, oninput is not supported in IE10, so your best bet is to combine the two event handlers, like this:

<span id="valBox"></span>
<input type="range" min="5" max="10" step="1" 
   oninput="showVal(this.value)" onchange="showVal(this.value)">

Find Arabic chars and replace them with its UTF-8 encoding. some thing like this:

for (int i = 0; i < urlAsString.length(); i++) {
    if (urlAsString.charAt(i) > 255) {
        urlAsString = urlAsString.substring(0, i) + URLEncoder.encode(urlAsString.charAt(i)+"", "UTF-8") + urlAsString.substring(i+1);
    }
}
encodedURL = urlAsString;

//initialize the 2D vector first

vector<vector<int>> matrix;

//initialize the 1D vector you would like to insert into matrix

vector<int> row;

//initializing row with values

row.push_back(val1);

row.push_back(val2);

//now inserting values into matrix

matrix.push_back(row);

//output- [[val1,val2]]

Use files.exclude:

• Go to File -> Preferences -> Settings (or on Mac Code -> Preferences -> Settings)
• Pick the workspace settings tab

• Add this code to the settings.json file displayed on the right side:

  // Place your settings in this file to overwrite default and user settings.
  
  {
      "settings": {
          "files.exclude": {
              "**/.git": true,         // this is a default value
              "**/.DS_Store": true,    // this is a default value
  
              "**/node_modules": true, // this excludes all folders 
                                      // named "node_modules" from 
                                      // the explore tree
  
              // alternative version
              "node_modules": true    // this excludes the folder 
                                      // only from the root of
                                      // your workspace 
          }
      }
  }
  

If you chose File -> Preferences -> User Settings then you configure the exclude folders globally for your current user.

Easiest way is to start a WinForms application, go to settings and change the type to a console application.

var i = 10;
i = i / -1;

Result: -10

var i = -10;
i = i / -1;

Result: 10

If you divide by negative 1, it will always flip your number either way.

You can use Jackson Mixins. For example:

class YourClass {
  public int ignoreThis() { return 0; }    
}

With this Mixin

abstract class MixIn {
  @JsonIgnore abstract int ignoreThis(); // we don't need it!  
}

With this:

objectMapper.getSerializationConfig().addMixInAnnotations(YourClass.class, MixIn.class);

Edit:

Thanks to the comments, with Jackson 2.5+, the API has changed and should be called with objectMapper.addMixIn(Class<?> target, Class<?> mixinSource)

Following changes you have to make that's it(change architecture into armv7 and remove others) :-

Unfortunately MySQL does not feature a split string function. However you can create a user defined function for this, such as the one described in the following article:

• MySQL Split String Function by Federico Cargnelutti

With that function:

DELIMITER $$

CREATE FUNCTION SPLIT_STR(
  x VARCHAR(255),
  delim VARCHAR(12),
  pos INT
)
RETURNS VARCHAR(255) DETERMINISTIC
BEGIN 
    RETURN REPLACE(SUBSTRING(SUBSTRING_INDEX(x, delim, pos),
       LENGTH(SUBSTRING_INDEX(x, delim, pos -1)) + 1),
       delim, '');
END$$

DELIMITER ;

you would be able to build your query as follows:

SELECT SPLIT_STR(membername, ' ', 1) as memberfirst,
       SPLIT_STR(membername, ' ', 2) as memberlast
FROM   users;

If you prefer not to use a user defined function and you do not mind the query to be a bit more verbose, you can also do the following:

SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(membername, ' ', 1), ' ', -1) as memberfirst,
       SUBSTRING_INDEX(SUBSTRING_INDEX(membername, ' ', 2), ' ', -1) as memberlast
FROM   users;

Setting cookies for another domain is not possible.

If you want to pass data to another domain, you can encode this into the url.

a.com  ->  b.com/redirect?info=some+info (and set cookie) -> b.com/other+page

I had these choices:

-----------------------------------------------
*  1           /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/bin/java
 + 2           /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java
   3           /home/ec2-user/local/java/jre1.7.0_25/bin/java

When I chose 3, it didn't work. When I chose 2, it did work.

You can get this error if you use wrong mode when opening the file. For example:

    with open(output, 'wb') as output_file:
        print output_file.read()

In that code, I want to read the file, but I use mode wb instead of r or r+

SQL Server drops and recreates the tables only if you:

• Add a new column
• Change the Allow Nulls setting for a column
• Change the column order in the table
• Change the column data type

Using ALTER is safer, as in case the metadata is lost while you re-create the table, your data will be lost.

iPad Media Queries (All generations - including iPad mini)

Thanks to Apple's work in creating a consistent experience for users, and easy time for developers, all 5 different iPads (iPads 1-5 and iPad mini) can be targeted with just one CSS media query. The next few lines of code should work perfect for a responsive design.

Query Helper Methods for codeigniter-3

If you paste

A.do() {
  if (condition1) {
   X.doSomething
  } else if (condition2) {
   Y.doSomethingElse
  } else {
   donotDoAnything
  }
}

onto https://www.zenuml.com. It will generate a diagram for you.

With JavaScript:

window.parent.location.href= "http://www.google.com";

If you're simply sharing a counter, consider using an AtomicInteger or another suitable class from the java.util.concurrent.atomic package:

public class Test {

    private final static AtomicInteger count = new AtomicInteger(0); 

    public void foo() {  
        count.incrementAndGet();
    }  
}

This can be done in a functional way with Java 9 using regular expression:

Pattern.compile(Pattern.quote(guess)) // sanitize input and create pattern
            .matcher(word) // create matcher
            .results()     // get the MatchResults, Java 9 method
            .map(MatchResult::start) // get the first index
            .collect(Collectors.toList()) // collect found indices into a list
    );

Here's the Kotlin Solution to add this logic as a new a new methods into CharSequence API using extension method:

 // Extension method
fun CharSequence.indicesOf(input: String): List<Int> =
    Regex(Pattern.quote(input)) // build regex
        .findAll(this)          // get the matches
        .map { it.range.first } // get the index
        .toCollection(mutableListOf()) // collect the result as list

// call the methods as
"Banana".indicesOf("a") // [1, 3, 5]

Application.Exit
    End

will work like a charm The "END" immediately terminates further execution while "Application.Exit" closes all forms and calls.

The best way to load an image is through the ImageIO API

BufferedImage img = ImageIO.read(new File("/path/to/some/image"));

There are a number of ways you can render an image to the screen.

You could use a JLabel. This is the simplest method if you don't want to modify the image in anyway...

JLabel background = new JLabel(new ImageIcon(img));

Then simply add it to your window as you see fit. If you need to add components to it, then you can simply set the label's layout manager to whatever you need and add your components.

If, however, you need something more sophisticated, need to change the image somehow or want to apply additional effects, you may need to use custom painting.

First cavert: Don't ever paint directly to a top level container (like JFrame). Top level containers aren't double buffered, so you may end up with some flashing between repaints, other objects live on the window, so changing it's paint process is troublesome and can cause other issues and frames have borders which are rendered inside the viewable area of the window...

Instead, create a custom component, extending from something like JPanel. Override it's paintComponent method and render your output to it, for example...

protected void paintComponent(Graphics g) {
    super.paintComponent(g);
    g.drawImage(img, 0, 0, this);
}

Take a look at Performing Custom Painting and 2D Graphics for more details

Reading quickly through the source it seems that you're not far off. The following link should help (I did something similar but for FTP). For a file send from server to client, you start off with a file instance and an array of bytes. You then read the File into the byte array and write the byte array to the OutputStream which corresponds with the InputStream on the client's side.

http://www.rgagnon.com/javadetails/java-0542.html

Edit: Here's a working ultra-minimalistic file sender and receiver. Make sure you understand what the code is doing on both sides.

unicode_escape doesn't work in general

It turns out that the string_escape or unicode_escape solution does not work in general -- particularly, it doesn't work in the presence of actual Unicode.

If you can be sure that every non-ASCII character will be escaped (and remember, anything beyond the first 128 characters is non-ASCII), unicode_escape will do the right thing for you. But if there are any literal non-ASCII characters already in your string, things will go wrong.

unicode_escape is fundamentally designed to convert bytes into Unicode text. But in many places -- for example, Python source code -- the source data is already Unicode text.

The only way this can work correctly is if you encode the text into bytes first. UTF-8 is the sensible encoding for all text, so that should work, right?

The following examples are in Python 3, so that the string literals are cleaner, but the same problem exists with slightly different manifestations on both Python 2 and 3.

>>> s = 'naïve \\t test'
>>> print(s.encode('utf-8').decode('unicode_escape'))
naïve   test

Well, that's wrong.

The new recommended way to use codecs that decode text into text is to call codecs.decode directly. Does that help?

>>> import codecs
>>> print(codecs.decode(s, 'unicode_escape'))
naïve   test

Not at all. (Also, the above is a UnicodeError on Python 2.)

The unicode_escape codec, despite its name, turns out to assume that all non-ASCII bytes are in the Latin-1 (ISO-8859-1) encoding. So you would have to do it like this:

>>> print(s.encode('latin-1').decode('unicode_escape'))
naïve    test

But that's terrible. This limits you to the 256 Latin-1 characters, as if Unicode had never been invented at all!

>>> print('Erno \\t Rubik'.encode('latin-1').decode('unicode_escape'))
UnicodeEncodeError: 'latin-1' codec can't encode character '\u0151'
in position 3: ordinal not in range(256)

Adding a regular expression to solve the problem

(Surprisingly, we do not now have two problems.)

What we need to do is only apply the unicode_escape decoder to things that we are certain to be ASCII text. In particular, we can make sure only to apply it to valid Python escape sequences, which are guaranteed to be ASCII text.

The plan is, we'll find escape sequences using a regular expression, and use a function as the argument to re.sub to replace them with their unescaped value.

import re
import codecs

ESCAPE_SEQUENCE_RE = re.compile(r'''
    ( \\U........      # 8-digit hex escapes
    | \\u....          # 4-digit hex escapes
    | \\x..            # 2-digit hex escapes
    | \\[0-7]{1,3}     # Octal escapes
    | \\N\{[^}]+\}     # Unicode characters by name
    | \\[\\'"abfnrtv]  # Single-character escapes
    )''', re.UNICODE | re.VERBOSE)

def decode_escapes(s):
    def decode_match(match):
        return codecs.decode(match.group(0), 'unicode-escape')

    return ESCAPE_SEQUENCE_RE.sub(decode_match, s)

And with that:

>>> print(decode_escapes('Erno \\t Rubik'))
Erno     Rubik

'^(part1|part2|part1,part2)$'

does it work?

First, you really need to keep in mind that it's never impossible to reverse-engineer something. Everything is hackable. A smart developer using a smart IDE can already get far enough.

Well, you can find here a list. ProGuard is pretty good. I've used it myself, but only to "minify" Java code.

Use Set in Python

>>> a = [2,4]
>>> b = [1,4,3]
>>> set(a) - set(b)
set([2])

A dictionary is not indexed, but it is in some way, ordered. The following would give you the first existing key:

list(my_dict.keys())[0]

Try this:

SELECT
    table_rows "Rows Count"
FROM
    information_schema.tables
WHERE
    table_name="Table_Name"
AND
    table_schema="Database_Name";

if(!preg_match('/^[\w-]+$/', $string1)) {
   echo "String 1 not acceptable acceptable";
   // String2 acceptable
}

There is charts4j which is a charts and graphs API. It enables developers to programmatically create the charts available in the Google Chart API through a straightforward and intuitive Java API.

Disclaimer: I wrote charts4j. We will be doing another major release in the next few weeks.

Answering late to mention yet another option rather than the common MAVEN_OPTS environment variable to pass to the Maven build the required JVM options.

Since Maven 3.3.1, you could have an .mvn folder as part of the concerned project and a jvm.config file as perfect place for such an option.

two new optional configuration files .mvn/jvm.config and .mvn/maven.config, located at the base directory of project source tree. If present, these files will provide default jvm and maven options. Because these files are part of the project source tree, they will be present in all project checkouts and will be automatically used every time the project is build.

As part of the official release notes

In Maven it is not simple to define JVM configuration on a per project base. The existing mechanism based on an environment variable MAVEN_OPTS and the usage of ${user.home}/.mavenrc is an other option with the drawback of not being part of the project.

Starting with this release you can define JVM configuration via ${maven.projectBasedir}/.mvn/jvm.config file which means you can define the options for your build on a per project base. This file will become part of your project and will be checked in along with your project. So no need anymore for MAVEN_OPTS, .mavenrc files. So for example if you put the following JVM options into the ${maven.projectBasedir}/.mvn/jvm.config file:

-Xmx2048m -Xms1024m -XX:MaxPermSize=512m -Djava.awt.headless=true

The main advantage of this approach is that the configuration is isolated to the concerned project and applied to the whole build as well, and less fragile than MAVEN_OPTS for other developers working on the same project (forgetting to setting it).
Moreover, the options will be applied to all modules in case of a multi-module project.

I am getting the error (...) javax.naming.NameNotFoundException: greetJndi not bound

This means that nothing is bound to the jndi name greetJndi, very likely because of a deployment problem given the incredibly low quality of this tutorial (check the server logs). I'll come back on this.

Is there any specific directory structure to deploy in JBoss?

The internal structure of the ejb-jar is supposed to be like this (using the poor naming conventions and the default package as in the mentioned link):

.
+-- greetBean.java
+-- greetHome.java
+-- greetRemote.java
+-- META-INF
    +-- ejb-jar.xml
    +-- jboss.xml

But as already mentioned, this tutorial is full of mistakes:

• there is an extra character (<enterprise-beans>] <-- HERE) in the ejb-jar.xml (!)
• a space is missing after PUBLIC in the ejb-jar.xml and jboss.xml (!!)
• the jboss.xml is incorrect, it should contain a session element instead of entity (!!!)

Here is a "fixed" version of the ejb-jar.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd">
<ejb-jar>
  <enterprise-beans>
    <session>
      <ejb-name>greetBean</ejb-name>
      <home>greetHome</home>
      <remote>greetRemote</remote>
      <ejb-class>greetBean</ejb-class>
      <session-type>Stateless</session-type>
      <transaction-type>Container</transaction-type>
    </session>
  </enterprise-beans>
</ejb-jar>

And of the jboss.xml:

<?xml version="1.0"?>
<!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS 3.2//EN" "http://www.jboss.org/j2ee/dtd/jboss_3_2.dtd">
<jboss>
  <enterprise-beans>
    <session>
      <ejb-name>greetBean</ejb-name>
      <jndi-name>greetJndi</jndi-name>
    </session>
  </enterprise-beans>
</jboss>

After doing these changes and repackaging the ejb-jar, I was able to successfully deploy it:

21:48:06,512 INFO  [Ejb3DependenciesDeployer] Encountered deployment AbstractVFSDeploymentContext@5060868{vfszip:/home/pascal/opt/jboss-5.1.0.GA/server/default/deploy/greet.jar/}

That tutorial needs significant improvement; I'd advise from staying away from roseindia.net.

git reset and git clean can be overkill in some situations (and be a huge waste of time).

If you simply have a message like "The following untracked files would be overwritten..." and you want the remote/origin/upstream to overwrite those conflicting untracked files, then git checkout -f <branch> is the best option.

If you're like me, your other option was to clean and perform a --hard reset then recompile your project.

To get the post by George Howarth working properly with more than one replacement you need to remove the break, assign the output to a variable ($line) and then output the variable:

$lookupTable = @{
    'something1' = 'something1aa'
    'something2' = 'something2bb'
    'something3' = 'something3cc'
    'something4' = 'something4dd'
    'something5' = 'something5dsf'
    'something6' = 'something6dfsfds'
}

$original_file = 'path\filename.abc'
$destination_file =  'path\filename.abc.new'

Get-Content -Path $original_file | ForEach-Object {
    $line = $_

    $lookupTable.GetEnumerator() | ForEach-Object {
        if ($line -match $_.Key)
        {
            $line = $line -replace $_.Key, $_.Value
        }
    }
   $line
} | Set-Content -Path $destination_file

If your dropping the database in SQL Management Studio and you get the message, don't forget that you use Master as selected database otherwise your query is also an connection to the database.

USE Master;
GO
DROP DATABASE AdventureWorks;
GO

You cannot do it with just method, unless you use some javascript framework like jquery which supports it ..

string s = '<div id="myDiv"></div>'
var htmlObject = $(s); // jquery call

but still, it would not be found by the getElementById because for that to work the element must be in the DOM... just creating in the memory does not insert it in the dom.

You would need to use append or appendTo or after etc.. to put it in the dom first..

Of'course all these can be done through regular javascript but it would take more steps to accomplish the same thing... and the logic is the same in both cases..

Try something like this - it works for the cases you have mentioned.

select * from tbl
where answer like '%[0-9]%'
and answer not like '%[:]%'
and answer not like '%[A-Z]%'

GRANT on the database is not what you need. Grant on the tables directly.

Granting privileges on the database mostly is used to grant or revoke connect privileges. This allows you to specify who may do stuff in the database if they have sufficient other permissions.

You want instead:

 GRANT ALL PRIVILEGES ON TABLE side_adzone TO jerry;

This will take care of this issue.

Modern Solution

The result is that the circle never gets distorted and the text stays exactly in the middle of the circle - vertically and horizontally.

.circle {
  background: gold;
  width: 40px; 
  height: 40px;
  border-radius: 50%;
  display: flex; /* or inline-flex */
  align-items: center; 
  justify-content: center;
}

<div class="circle">text</div>

Simple and easy to use. Enjoy!

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

If you have node then you can use fs like in this answer to get all the files:

const { resolve } = require('path'),
  { readdir } = require('fs').promises;

async function getFiles(dir) {
  const dirents = await readdir(dir, { withFileTypes: true });
  const files = await Promise.all(dirents.map((dirent) => {
    const res = resolve(dir, dirent.name);
    return dirent.isDirectory() ? getFiles(res) : res;
  }));
  return Array.prototype.concat(...files);
}

And you might use that like this:

const directory = "./Documents/";
  
getFiles(directory).then(results => {
  const html = `<ul>` +
  results.map(fileOrDirectory => `<li>${fileOrDirectory}</li>`).join('\n') +
  `</ul>`;

  process.stdout.write(html);
  // or you could use something like fs.writeFile to write the file directly
});

You could call it at the command-line with something like this:

$ node thatScript.js > index.html

window.WindowStyle = WindowStyle.None;
window.ResizeMode = ResizeMode.NoResize;
window.Left = 0;
window.Top = 0;
window.Width = SystemParameters.VirtualScreenWidth;
window.Height = SystemParameters.VirtualScreenHeight;
window.Topmost = true;

Works with multiple screens

You can use the DataFrame head and tail methods as syntactic sugar instead of slicing/loc here. I use a split size of 3; for your example use headSize=10

def split(df, headSize) :
    hd = df.head(headSize)
    tl = df.tail(len(df)-headSize)
    return hd, tl

df = pd.DataFrame({    'A':[2,4,6,8,10,2,4,6,8,10],
                       'B':[10,-10,0,20,-10,10,-10,0,20,-10],
                       'C':[4,12,8,0,0,4,12,8,0,0],
                      'D':[9,10,0,1,3,np.nan,np.nan,np.nan,np.nan,np.nan]})

# Split dataframe into top 3 rows (first) and the rest (second)
first, second = split(df, 3)

(ES5) I use forEach to iterate on the collection returned by querySelectorAll and it works well :

document.querySelectorAll('your_selector').forEach(item => { /* do the job with item element */ });

A simple Approach can be if your Columns are of Simple Type like String

public static IEnumerable<MyObject> WhereQuery(IEnumerable<MyObject> source, string columnName, string propertyValue)
{
   return source.Where(m => { return m.GetType().GetProperty(columnName).GetValue(m, null).ToString().StartsWith(propertyValue); });
}

For me they were appearing when i transferred code manually to another laptop. Just do

File>Invalidate Cache/Restart

click on 'Invalidate Cache and Restart' and your are done.

I had same issue and I solved it by "pod setup" after installing cocoapods.

Think like this:

class Animal { /* Some virtual members */ };
class Dog: public Animal {};
class Cat: public Animal {};


Dog     dog;
Cat     cat;
Animal& AnimalRef1 = dog;  // Notice no cast required. (Dogs and cats are animals).
Animal& AnimalRef2 = cat;
Animal* AnimalPtr1 = &dog;
Animal* AnimlaPtr2 = &cat;

Cat&    catRef1 = dynamic_cast<Cat&>(AnimalRef1);  // Throws an exception  AnimalRef1 is a dog
Cat*    catPtr1 = dynamic_cast<Cat*>(AnimalPtr1);  // Returns NULL         AnimalPtr1 is a dog
Cat&    catRef2 = dynamic_cast<Cat&>(AnimalRef2);  // Works
Cat*    catPtr2 = dynamic_cast<Cat*>(AnimalPtr2);  // Works

// This on the other hand makes no sense
// An animal object is not a cat. Therefore it can not be treated like a Cat.
Animal  a;
Cat&    catRef1 = dynamic_cast<Cat&>(a);    // Throws an exception  Its not a CAT
Cat*    catPtr1 = dynamic_cast<Cat*>(&a);   // Returns NULL         Its not a CAT.

Now looking back at your first statement:

Animal   animal = cat;    // This works. But it slices the cat part out and just
                          // assigns the animal part of the object.
Cat      bigCat = animal; // Makes no sense.
                          // An animal is not a cat!!!!!
Dog      bigDog = bigCat; // A cat is not a dog !!!!

You should very rarely ever need to use dynamic cast.
This is why we have virtual methods:

void makeNoise(Animal& animal)
{
     animal.DoNoiseMake();
}

Dog    dog;
Cat    cat;
Duck   duck;
Chicken chicken;

makeNoise(dog);
makeNoise(cat);
makeNoise(duck);
makeNoise(chicken);

The only reason I can think of is if you stored your object in a base class container:

std::vector<Animal*>  barnYard;
barnYard.push_back(&dog);
barnYard.push_back(&cat);
barnYard.push_back(&duck);
barnYard.push_back(&chicken);

Dog*  dog = dynamic_cast<Dog*>(barnYard[1]); // Note: NULL as this was the cat.

But if you need to cast particular objects back to Dogs then there is a fundamental problem in your design. You should be accessing properties via the virtual methods.

barnYard[1]->DoNoiseMake();

Why don't you use a Bundle. From your first fragment, here's how to set it up:

Fragment fragment = new Fragment();
Bundle bundle = new Bundle();
bundle.putInt(key, value);
fragment.setArguments(bundle);

Then in your second Fragment, retrieve the data using:

Bundle bundle = this.getArguments();
int myInt = bundle.getInt(key, defaultValue);

Bundle has put methods for lots of data types. Please see http://developer.android.com/reference/android/os/Bundle.html

To specify a callback function, you have to use an object as the first argument, and the callback function as the second argument.

echo '<script>
    setTimeout(function() {
        swal({
            title: "Wow!",
            text: "Message!",
            type: "success"
        }, function() {
            window.location = "redirectURL";
        });
    }, 1000);
</script>';

in C++ expression a % b returns remainder of division of a by b (if they are positive. For negative numbers sign of result is implementation defined). For example:

5 % 2 = 1
13 % 5 = 3

With this knowledge we can try to understand your code. Condition count % 6 == 5 means that newline will be written when remainder of division count by 6 is five. How often does that happen? Exactly 6 lines apart (excercise : write numbers 1..30 and underline the ones that satisfy this condition), starting at 6-th line (count = 5).

To get desired behaviour from your code, you should change condition to count % 5 == 4, what will give you newline every 5 lines, starting at 5-th line (count = 4).

It's a high level library for dealing with REST. It's OOP, works with JSON, but also works with any other format.

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

using (var fs = new FileStream(filePath, FileMode.Append, FileAccess.Write, FileShare.ReadWrite))
using (var sw = new StreamWriter(fs))
{
    sw.WriteLine(message);
}

In real life, if you are using a ORM like LINQ-to-SQL

• If you create an IQueryable, then the query may be converted to sql and run on the database server
• If you create an IEnumerable, then all rows will be pulled into memory as objects before running the query.

In both cases if you don't call a ToList() or ToArray() then query will be executed each time it is used, so, say, you have an IQueryable<T> and you fill 4 list boxes from it, then the query will be run against the database 4 times.

Also if you extent your query:

q.Where(x.name = "a").ToList()

Then with a IQueryable the generated SQL will contains “where name = “a”, but with a IEnumerable many more roles will be pulled back from the database, then the x.name = “a” check will be done by .NET.

I did it this way.

Create the directive

function finRepeat() {
    return function(scope, element, attrs) {
        if (scope.$last){
            // Here is where already executes the jquery
            $(document).ready(function(){
                $('.materialboxed').materialbox();
                $('.tooltipped').tooltip({delay: 50});
            });
        }
    }
}

angular
    .module("app")
    .directive("finRepeat", finRepeat);

After you add it on the label where this ng-repeat

<ul>
    <li ng-repeat="(key, value) in data" fin-repeat> {{ value }} </li>
</ul>

And ready with that will be run at the end of the ng-repeat.

You really need to keep two issues apart:

1) the primary key is a logical construct - one of the candidate keys that uniquely and reliably identifies every row in your table. This can be anything, really - an INT, a GUID, a string - pick what makes most sense for your scenario.

2) the clustering key (the column or columns that define the "clustered index" on the table) - this is a physical storage-related thing, and here, a small, stable, ever-increasing data type is your best pick - INT or BIGINT as your default option.

By default, the primary key on a SQL Server table is also used as the clustering key - but that doesn't need to be that way!

One rule of thumb I would apply is this: any "regular" table (one that you use to store data in, that is a lookup table etc.) should have a clustering key. There's really no point not to have a clustering key. Actually, contrary to common believe, having a clustering key actually speeds up all the common operations - even inserts and deletes (since the table organization is different and usually better than with a heap - a table without a clustering key).

Kimberly Tripp, the Queen of Indexing has a great many excellent articles on the topic of why to have a clustering key, and what kind of columns to best use as your clustering key. Since you only get one per table, it's of utmost importance to pick the right clustering key - and not just any clustering key.

• GUIDs as PRIMARY KEY and/or clustered key
• The clustered index debate continues
• Ever-increasing clustering key - the Clustered Index Debate..........again!
• Disk space is cheap - that's not the point!

The simple solution: Add the following to the very top of the php file you are requesting the data from.

header("Access-Control-Allow-Origin: *");

A standard-lib version (no pandas)

This assumes that the first row of the csv is the headers

import csv

# open the file in universal line ending mode 
with open('test.csv', 'rU') as infile:
  # read the file as a dictionary for each row ({header : value})
  reader = csv.DictReader(infile)
  data = {}
  for row in reader:
    for header, value in row.items():
      try:
        data[header].append(value)
      except KeyError:
        data[header] = [value]

# extract the variables you want
names = data['name']
latitude = data['latitude']
longitude = data['longitude']

Here is my answer -

files=(xorg-x11-fonts*)

if [ -e "${files[0]}" ];
then
    printf "BLAH"
fi

These days, socket.on('connect', ...) is not working for me. I use the below code to check at 1st connecting.

if (socket.connected)
  console.log('socket.io is connected.')

and use this code when reconnected.

socket.on('reconnect', ()=>{
  //Your Code Here
});

This has been edited a few times, and we have decided to call the main class that wraps a collection RangePrinter.

This should work automatically with any collection once you have written the one-time operator<< overload, except that you will need a special one for maps to print the pair, and may want to customize the delimiter there.

You could also have a special "print" function to use on the item instead of just outputting it directly, a bit like STL algorithms allow you to pass in custom predicates. With map you would use it this way, with a custom printer for the std::pair.

Your "default" printer would just output it to the stream.

Ok, let's work on a custom printer. I will change my outer class to RangePrinter. So we have 2 iterators and some delimiters but have not customized how to print the actual items.

struct DefaultPrinter
{
   template< typename T >
   std::ostream & operator()( std::ostream& os, const T& t ) const
   {
     return os << t;
   }

   // overload for std::pair
   template< typename K, typename V >
   std::ostream & operator()( std::ostream & os, std::pair<K,V> const& p)
   {
      return os << p.first << '=' << p.second;
   }
};

// some prototypes
template< typename FwdIter, typename Printer > class RangePrinter;

template< typename FwdIter, typename Printer > 
  std::ostream & operator<<( std::ostream &, 
        RangePrinter<FwdIter, Printer> const& );

template< typename FwdIter, typename Printer=DefaultPrinter >
class RangePrinter
{
    FwdIter begin;
    FwdIter end;
    std::string delim;
    std::string open;
    std::string close;
    Printer printer;

    friend std::ostream& operator<< <>( std::ostream&, 
         RangePrinter<FwdIter,Printer> const& );

public:
    RangePrinter( FwdIter b, FwdIter e, Printer p,
         std::string const& d, std::string const & o, std::string const& c )
      : begin( b ), end( e ), printer( p ), open( o ), close( c )
    {
    } 

     // with no "printer" variable
    RangePrinter( FwdIter b, FwdIter e,
         std::string const& d, std::string const & o, std::string const& c )
      : begin( b ), end( e ), open( o ), close( c )
    {
    } 

};


template<typename FwdIter, typename Printer>
std::ostream& operator<<( std::ostream& os, 
          RangePrinter<FwdIter, Printer> const& range )
{
    const Printer & printer = range.printer;

    os << range.open;
    FwdIter begin = range.begin, end = range.end;

    // print the first item
    if (begin == end) 
    { 
      return os << range.close; 
    }

    printer( os, *begin );

    // print the rest with delim as a prefix
    for( ++begin; begin != end; ++begin )
    {
       os << range.delim;
       printer( os, *begin );
    }
    return os << range.close;
}

Now by default it will work for maps as long as the key and value types are both printable and you can put in your own special item printer for when they are not (as you can with any other type), or if you do not want "=" as the delimiter.

I am moving the free-function to create these to the end now:

A free-function (iterator version) would look like something this and you could even have defaults:

template<typename Collection>
RangePrinter<typename Collection::const_iterator> rangePrinter
    ( const Collection& coll, const char * delim=",", 
       const char * open="[", const char * close="]")
{
   return RangePrinter< typename Collection::const_iterator >
     ( coll.begin(), coll.end(), delim, open, close );
}

You could then use it for std::set by

 std::cout << outputFormatter( mySet );

You can also write free-function version that take a custom printer and ones that take two iterators. In any case they will resolve the template parameters for you, and you will be able to pass them through as temporaries.

If someone used homebrew with Mojave or later:

export PATH=/usr/local/opt/[email protected]/bin:$PATH

change version if you need!

Try configuration at /config/application.rb:

config.middleware.insert_before 0, "Rack::Cors" do
  allow do
    origins '*'
    resource '*', :headers => :any, :methods => [:get, :post, :options, :delete, :put, :patch], credentials: true
  end
end

Add <input> to <td> when it is clicked. Change <input> to <span> when it is blurred.

document.getElementById("placehere").appendChild(elem);

not

document.getElementById("placehere").appendChild("elem");

and use the below to set the source

elem.src = 'images/hydrangeas.jpg';

You can do this as follows on SQL Server 2008 or greater:

SELECT CONVERT(datetime, 
               SWITCHOFFSET(CONVERT(datetimeoffset, 
                                    MyTable.UtcColumn), 
                            DATENAME(TzOffset, SYSDATETIMEOFFSET()))) 
       AS ColumnInLocalTime
FROM MyTable

You can also do the less verbose:

SELECT DATEADD(mi, DATEDIFF(mi, GETUTCDATE(), GETDATE()), MyTable.UtcColumn) 
       AS ColumnInLocalTime
FROM MyTable

Whatever you do, do not use - to subtract dates, because the operation is not atomic, and you will on occasion get indeterminate results due to race conditions between the system datetime and the local datetime being checked at different times (i.e., non-atomically).

Hit the Esc key to enter "Normal mode". Then you can type : to enter "Command-line mode". A colon (:) will appear at the bottom of the screen and you can type in one of the following commands. To execute a command, press the Enter key.

• :q to quit (short for :quit)
• :q! to quit without saving (short for :quit!)
• :wq to write and quit
• :wq! to write and quit even if file has only read permission (if file does not have write permission: force write)
• :x to write and quit (similar to :wq, but only write if there are changes)
• :exit to write and exit (same as :x)
• :qa to quit all (short for :quitall)
• :cq to quit without saving and make Vim return non-zero error (i.e. exit with error)

You can also exit Vim directly from "Normal mode" by typing ZZ to save and quit (same as :x) or ZQ to just quit (same as :q!). (Note that case is important here. ZZ and zz do not mean the same thing.)

Vim has extensive help - that you can access with the :help command - where you can find answers to all your questions and a tutorial for beginners.

This is a quick way to do that, I mean.

It does not use an expensive regex function. It also does not use multiple replacement functions that each individually did loop over the data with several checks, allocations, etc.

So the search is done directly in one for loop. For the number of times that the capacity of the result array has to be increased, a loop is also used within the Array.Copy function. That are all the loops. In some cases, a larger page size might be more efficient.

public static string NormalizeNewLine(this string val)
{
    if (string.IsNullOrEmpty(val))
        return val;

    const int page = 6;
    int a = page;
    int j = 0;
    int len = val.Length;
    char[] res = new char[len];

    for (int i = 0; i < len; i++)
    {
        char ch = val[i];

        if (ch == '\r')
        {
            int ni = i + 1;
            if (ni < len && val[ni] == '\n')
            {
                res[j++] = '\r';
                res[j++] = '\n';
                i++;
            }
            else
            {
                if (a == page) // Ensure capacity
                {
                    char[] nres = new char[res.Length + page];
                    Array.Copy(res, 0, nres, 0, res.Length);
                    res = nres;
                    a = 0;
                }

                res[j++] = '\r';
                res[j++] = '\n';
                a++;
            }
        }
        else if (ch == '\n')
        {
            int ni = i + 1;
            if (ni < len && val[ni] == '\r')
            {
                res[j++] = '\r';
                res[j++] = '\n';
                i++;
            }
            else
            {
                if (a == page) // Ensure capacity
                {
                    char[] nres = new char[res.Length + page];
                    Array.Copy(res, 0, nres, 0, res.Length);
                    res = nres;
                    a = 0;
                }

                res[j++] = '\r';
                res[j++] = '\n';
                a++;
            }
        }
        else
        {
            res[j++] = ch;
        }
    }

    return new string(res, 0, j);
}

I now that '\n\r' is not actually used on basic platforms. But who would use two types of linebreaks in succession to indicate two linebreaks?

If you want to know that, then you need to take a look before to know if the \n and \r both are used separately in the same document.

In addition to the other suggestions - you can also wrap the flag in a control class and make a final instance of it in your parent class:

public class Test {
  class Control {
    public volatile boolean flag = false;
  }
  final Control control = new Control();

  class T1 implements Runnable {
    @Override
    public void run() {
      while ( !control.flag ) {

      }
    }
  }

  class T2 implements Runnable {
    @Override
    public void run() {
      while ( !control.flag ) {

      }
    }
  }

  private void test() {
    T1 main = new T1();
    T2 help = new T2();

    new Thread(main).start();
    new Thread(help).start();
  }

  public static void main(String[] args) throws InterruptedException {
    try {
      Test test = new Test();
      test.test();
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

If you want to notify your JTable about changes of your data, use
tableModel.fireTableDataChanged()

From the documentation:

Notifies all listeners that all cell values in the table's rows may have changed. The number of rows may also have changed and the JTable should redraw the table from scratch. The structure of the table (as in the order of the columns) is assumed to be the same.

There really aren't any differences.

" is processed as " which is the decimal equivalent of &x22; which is the ISO 8859-1 equivalent of ".

The only reason you may be against using " is because it was mistakenly omitted from the HTML 3.2 specification.

Otherwise it all boils down to personal preference.

Thanks!

Since a jQuery object inherits from an array, and this array contains the selected DOM elements. Saying you're using an id and so the element should be unique within the DOM, you could perform a direct call to submit by doing :

$(".nextbutton").click(function() { 
  $("#formID")[0].submit();
});

In iOS7 I found that if I had a View inside a UIScrollView on a FreeForm-sized ViewController it would not scroll in the app, no matter what I did. I played around and found the following seemed to work, which uses no FreeForms:

1. Insert a UIScrollView inside the main View of a ViewController

2. Set the Autolayout constraints on the ScrollView as appropriate. For me I used 0 to Top Layout guide and 0 to Bottom layout Guide

3. Inside the ScrollView, place a Container View. Set its height to whatever you want (e.g. 1000)

4. Add a Height constraint (1000) to the Container so it doesn't resize. The bottom will be past the end of the form.

5. Add the line [self.scrollView setContentSize:CGSizeMake(320, 1000)]; to the ViewController that contains the scrollView (which you've hooked up as a IBOutlet)

The ViewController (automatically added) that is associated with the Container will have the desired height (1000) in Interface Builder and will also scroll properly in the original view controller. You can now use the container's ViewController to layout your controls.

Yes, localhost just means that you are talking to the webserver om the same machine that you are currently using.

Other servers are contacted through either their IP-address or a given name.

Updated the Android SDK platform tools using SDK Manager (in Eclipse). Works for me.

I faced the same error, in my case I miss-spelled ng-model directive something like "ng-moel"

Wrong one: ng-moel="user.name" Right one: ng-model="user.name"

object-fit: cover will do exactly what you need.

But it might not work on IE/Edge. Follow as shown below to fix it with just CSS to work on all browsers.

The approach I took was to position the image inside the container with absolute and then place it right at the centre using the combination:

position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);

Once it is in the centre, I give to the image,

// For vertical blocks (i.e., where height is greater than width)
height: 100%;
width: auto;

// For Horizontal blocks (i.e., where width is greater than height)
height: auto;
width: 100%;

This makes the image get the effect of Object-fit:cover.

Here is a demonstration of the above logic.

https://jsfiddle.net/furqan_694/s3xLe1gp/

This logic works in all browsers.

Original Image

Vertically Cropped

Horizontally Cropped

Compiler by itself would not know that the conditions you have given are optimum .. meaning of this is you have covered all cases .. So therefore it always wants a return statement ... So either you can change last else if with else or just write return 0 after last else if ;`int binary(int val, int sorted[], int low, int high) { int mid = (low+high)/2;

if(high < low)
    return -1;

if(val < sorted[mid])
    return binary(val, sorted, low, mid-1);

else if(val > sorted[mid])
    return binary(val, sorted, mid+1, high);

else if(val == sorted[mid])
    return mid;
return 0; }`

Isn't this the simplest way?

colorRampPalette could be your friend here:

colfunc <- colorRampPalette(c("black", "white"))
colfunc(10)
# [1] "#000000" "#1C1C1C" "#383838" "#555555" "#717171" "#8D8D8D" "#AAAAAA"
# [8] "#C6C6C6" "#E2E2E2" "#FFFFFF"

And just to show it works:

plot(rep(1,10),col=colfunc(10),pch=19,cex=3)

Following environment variables worked for me on Debian Wheezy 7 and Tomcat 7:

CATALINA_HOME=/usr/share/tomcat7
CATALINA_BASE=/var/lib/tomcat7
CATALINA_TMPDIR=/tmp/tomcat7

(I did create /tmp/tomcat7 manually)

You need to use Regular Expression For Website URL it is

var urlPattern = /(http|ftp|https)://[\w-]+(.[\w-]+)+([\w.,@?^=%&:/~+#-]*[\w@?^=%&/~+#-])?/

Use this Expression as in example

var regex = new RegExp(urlPattern ); var t = 'www.google.com';
var res = t.match(regex /g);

For You have to pass your web page as string to this javascript in variable t and get array

Your code won't work because you haven't assigned anything to n before you first use it. Try this:

def oracle():
    n = None
    while n != 'Correct':
        # etc...

A more readable approach is to move the test until later and use a break:

def oracle():
    guess = 50

    while True:
        print 'Current number = {0}'.format(guess)
        n = raw_input("lower, higher or stop?: ")
        if n == 'stop':
            break
        # etc...

Also input in Python 2.x reads a line of input and then evaluates it. You want to use raw_input.

Note: In Python 3.x, raw_input has been renamed to input and the old input method no longer exists.

For the latest VS2015 sp3, the command line shoud be:

Use the R method packageDescription to get the installed package description and for version just use $Version as:

In my case, using Windows 10 and conda 4.6.11, by running the commands

conda install nb_conda

conda install -c conda-forge nb_conda_kernels

from the terminal while having the environment active didn't do the job after I opened Jupyter from the same command line using conda jupyter notebook.

The solution was apparently to opened Jupyter from the Anaconda Navigator by going to my environment in Environments: Open Anaconda Navigator, select the environment in Environments, press on the "play" button on the chosen environment, and select 'open with Jupyter Notebook'.

Environments in Anaconda Navigator to run Jupyter from the selected environment

you just have to change the name of your input filed because same name is required in parameter and input field name just replace this line Your code working fine

 <input type="file" name="file" />

I had this issue when i cloned from a git repository and I had it resolved when I created a new project and re-inserted the src folder from the old project.

The src folder is the only folder needed when deploying your angular application but you must reconfigure the dev environment, using this solution.

In case of Windows(in my case XP):-

1. Check the directory where tomcat is installed.
2. Open the directory called \conf in it.
3. Then search file server.xml
4. Open that file and check what is the connector port for HTTP,whre you will found something like 8009,8080 etc.
5. Suppose it found 8009,use that port as "/localhost:8009/" in your web-browser with HTTP protocol. Hope this will work !

Per the request of @skeller88, I am reposting my comment as an answer so that it doesn't get lost by people who don't read every response...

The problem with DataGrip is that it puts a grip on your wallet. It is not free. Try the community edition of DBeaver at dbeaver.io. It is a FOSS multi-platform database tool for SQL programmers, DBAs and analysts that supports all popular databases: MySQL, PostgreSQL, SQLite, Oracle, DB2, SQL Server, Sybase, MS Access, Teradata, Firebird, Hive, Presto, etc.

DBeaver Community Edition makes it trivial to connect to a database, issue queries to retrieve data, and then download the result set to save it to CSV, JSON, SQL, or other common data formats. It's a viable FOSS competitor to TOAD for Postgres, TOAD for SQL Server, or Toad for Oracle.

I have no affiliation with DBeaver. I love the price and functionality, but I wish they would open up the DBeaver/Eclipse application more and made it easy to add analytics widgets to DBeaver / Eclipse, rather than requiring users to pay for the annual subscription to create graphs and charts directly within the application. My Java coding skills are rusty and I don't feel like taking weeks to relearn how to build Eclipse widgets, only to find that DBeaver has disabled the ability to add third-party widgets to the DBeaver Community Edition.

Do DBeaver users have insight as to the steps to create analytics widgets to add into the Community Edition of DBeaver?

This is the code to subtract one date from another. This example converts the dates to objects as the getTime() function won't work unless it's an Date object.

    var dat1 = document.getElementById('inputDate').value;
                var date1 = new Date(dat1)//converts string to date object
                alert(date1);
                var dat2 = document.getElementById('inputFinishDate').value;
                var date2 = new Date(dat2)
                alert(date2);

                var oneDay = 24 * 60 * 60 * 1000; // hours*minutes*seconds*milliseconds
                var diffDays = Math.abs((date1.getTime() - date2.getTime()) / (oneDay));
                alert(diffDays);

You have to download and add the SQLite JDBC driver to your classpath.
You can download from here https://bitbucket.org/xerial/sqlite-jdbc/downloads

If you use Gradle, you will only have to add the SQLite dependency:

dependencies {
    compile 'org.xerial:sqlite-jdbc:3.8.11.2'
} 

Next thing you have to do is to initialize the driver:

try {
    Class.forName("org.sqlite.JDBC");
} catch (ClassNotFoundException eString) {
    System.err.println("Could not init JDBC driver - driver not found");
}

If you are looking for an objective analysis of both the editors, look at their origins and the philosophy behind their respective designs. Think, which one would suit you better and learn it (and learn it and learn it, because it takes time before you being to discover its true utility as against any IDE). An Introduction to Display Editing with Vi was written by Bill Joy and Mark Horton and he explains why he choose modal design and rationale for various key strokes ( it helps me to remember that CTRL-W +W (will switch to next Window and it will same for CTRL W+ CTRL W, just in case you held the CTRL key for a longer duration.

Here is a link to Emacs timeline and has the reference to Multics Emacs paper. Hereis RMS paper on Emacs, where I see the stress is on a programmable text editor (even way back in 1981 and before).

I have not read the emacs papers, but have read Bill Joy's vi paper a couple of times. Both are old, but still you will get the philosophy and you might choose to use the current tool (vim 7.x or emacs 25?)

Edit: I forgot to mention that it takes patience and imagination to read both these papers as it takes you back in time while reading it. But it is worth.

Just to extend Mark Byers's answer with an example:

import java.util.UUID;

public class RandomStringUUID {
    public static void main(String[] args) {
        UUID uuid = UUID.randomUUID();
        System.out.println("UUID=" + uuid.toString() );
    }
}

Your task declaration is incorrectly combining the Copy task type and project.copy method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File API) will do. Assuming Project1 is the project directory:

task renABCToXYZ {     doLast {         file("ABC").renameTo(file("XYZ"))     } } 

Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast task action) to the task that produces ABC.

Adding my two cents for those searching for "Ensure that the org.eclipse.core.runtime bundle is resolved and started":

Adding "arbitrary" bundles to the list of bundles just because it seems that they are missing is not always the best solution. Sometimes it can get quite frustrating, because those new plugins might depend on other missing bundles, which need even more bundles and so on...

So, before adding a new dependency to the list of required bundles, make sure you understand why the bundle is needed (the debugger is your friend!).

This question here doesn't provide enough information to make this a valid answer in all cases, but if you encounter the message that the org.eclipse.core.runtime is missing, try setting the eclipse.application.launchDefault system property to false, especially if you try to run an application which is not an "eclipse application" (but maybe just a headless runtime on top of equinox).

This link might come in handy: http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Fruntime-options.html, look for the eclipse.application.launchDefault system property.

As already pointed out by others, all the solutions above only change the working directory of the current process. This is lost when you exit back to the Unix shell. If desperate you can change the parent shell directory on Unix with this horrible hack:

def quote_against_shell_expansion(s):
    import pipes
    return pipes.quote(s)

def put_text_back_into_terminal_input_buffer(text):
    # use of this means that it only works in an interactive session
    # (and if the user types while it runs they could insert characters between the characters in 'text'!)
    import fcntl, termios
    for c in text:
        fcntl.ioctl(1, termios.TIOCSTI, c)

def change_parent_process_directory(dest):
    # the horror
    put_text_back_into_terminal_input_buffer("cd "+quote_against_shell_expansion(dest)+"\n")

Actually, as long as the parent element is positioned, you can set the child's height to 100%. Namely, in case you don't want the parent to be absolutely positioned. Let me explain further:

<style>
    #outer2 {
        padding-left: 23px;
        position: relative; 
        height:auto; 
        width:200px; 
        border: 1px solid red; 
    }
    #inner2 {
        left:0;
        position:absolute; 
        height:100%; 
        width:20px; 
        border: 1px solid black; 
    }
</style>

<div id='outer2'>
    <div id='inner2'>
    </div>
</div>

Modern C, aka C99, has variable length arrays, VLA. Unfortunately, not all compilers support this but if yours does this would be an alternative.

You could do this using SUMIF. This allows you to SUM a value in a cell IF a value in another cell meets the specified criteria. Here's an example:

 -   A         B
 1   100       YES
 2   100       YES
 3   100       NO

Using the formula: =SUMIF(B1:B3, "YES", A1:A3), you will get the result of 200.

Here's a screenshot of a working example I just did in Excel:

Try the sp_foreachdb procedure.

Use strtotime to generate a timestamp from the given string (interpreted as local time) and use gmdate to get it as a formatted UTC date back.

Example

As requested, here’s a simple example:

echo gmdate('d.m.Y H:i', strtotime('2012-06-28 23:55'));

I had the same issue as you, I figured it out. Facebook now roles some features as plugins. In the left hand side select Products and add product. Then select Facbook Login. Pretty straight forward from there, you'll see all the Oauth options show up.

The accepted answer of how to create an Index inline a Table creation script did not work for me. This did:

CREATE TABLE [dbo].[TableToBeCreated]
(
    [Id] BIGINT IDENTITY(1, 1) NOT NULL PRIMARY KEY
    ,[ForeignKeyId] BIGINT NOT NULL
    ,CONSTRAINT [FK_TableToBeCreated_ForeignKeyId_OtherTable_Id] FOREIGN KEY ([ForeignKeyId]) REFERENCES [dbo].[OtherTable]([Id])
    ,INDEX [IX_TableToBeCreated_ForeignKeyId] NONCLUSTERED ([ForeignKeyId])
)

Remember, Foreign Keys do not create Indexes, so it is good practice to index them as you will more than likely be joining on them.

There is actually an example for this type of issue in the Ant documentation. It makes use of Selectors (mentioned above) and mappers. See last example in http://ant.apache.org/manual/Types/dirset.html :

<dirset id="dirset" dir="${workingdir}">
   <present targetdir="${workingdir}">
        <mapper type="glob" from="*" to="*/${markerfile}" />
   </present>
</dirset>

Selects all directories somewhere under ${workingdir} which contain a ${markerfile}.

It is possible to build an arbitrary GET or POST request and send it to any server accessible to a victims browser. This includes devices on your local network, such as Printers and Routers.

There are many ways of building a CSRF exploit. A simple POST based CSRF attack can be sent using .submit() method. More complex attacks, such as cross-site file upload CSRF attacks will exploit CORS use of the xhr.withCredentals behavior.

CSRF does not violate the Same-Origin Policy For JavaScript because the SOP is concerned with JavaScript reading the server's response to a clients request. CSRF attacks don't care about the response, they care about a side-effect, or state change produced by the request, such as adding an administrative user or executing arbitrary code on the server.

Make sure your requests are protected using one of the methods described in the OWASP CSRF Prevention Cheat Sheet. For more information about CSRF consult the OWASP page on CSRF.

This turned out to be very flexible and extensible. $field =~ s/[^\x00-\x7F]//g ; # thus all non ASCII or specific items in question could be cleaned. Very nice either in selection or pre-processing of items that will eventually become hash keys.

Another example of correct compression and decompression:

@Slf4j
public class GZIPCompression {
    public static byte[] compress(final String stringToCompress) {
        if (isNull(stringToCompress) || stringToCompress.length() == 0) {
            return null;
        }

        try (final ByteArrayOutputStream baos = new ByteArrayOutputStream();
            final GZIPOutputStream gzipOutput = new GZIPOutputStream(baos)) {
            gzipOutput.write(stringToCompress.getBytes(UTF_8));
            gzipOutput.finish();
            return baos.toByteArray();
        } catch (IOException e) {
            throw new UncheckedIOException("Error while compression!", e);
        }
    }

    public static String decompress(final byte[] compressed) {
        if (isNull(compressed) || compressed.length == 0) {
            return null;
        }

        try (final GZIPInputStream gzipInput = new GZIPInputStream(new ByteArrayInputStream(compressed));
             final StringWriter stringWriter = new StringWriter()) {
            IOUtils.copy(gzipInput, stringWriter, UTF_8);
            return stringWriter.toString();
        } catch (IOException e) {
            throw new UncheckedIOException("Error while decompression!", e);
        }
    }
}

You need to put your main code on the OnStart method.

This other SO answer of mine might help.

You will need to put some code to enable debugging within visual-studio while maintaining your application valid as a windows-service. This other SO thread cover the issue of debugging a windows-service.

EDIT:

Please see also the documentation available here for the OnStart method at the MSDN where one can read this:

Do not use the constructor to perform processing that should be in OnStart. Use OnStart to handle all initialization of your service. The constructor is called when the application's executable runs, not when the service runs. The executable runs before OnStart. When you continue, for example, the constructor is not called again because the SCM already holds the object in memory. If OnStop releases resources allocated in the constructor rather than in OnStart, the needed resources would not be created again the second time the service is called.

With sed, I usually implement non-greedy search by searching for anything except the separator until the separator :

echo "http://www.suon.co.uk/product/1/7/3/" | sed -n 's;\(http://[^/]*\)/.*;\1;p'

Output:

http://www.suon.co.uk

this is:

• don't output -n
• search, match pattern, replace and print s/<pattern>/<replace>/p
• use ; search command separator instead of / to make it easier to type so s;<pattern>;<replace>;p
• remember match between brackets \( ... \), later accessible with \1,\2...
• match http://
• followed by anything in brackets [], [ab/] would mean either a or b or /
• first ^ in [] means not, so followed by anything but the thing in the []
• so [^/] means anything except / character
• * is to repeat previous group so [^/]* means characters except /.
• so far sed -n 's;\(http://[^/]*\) means search and remember http://followed by any characters except / and remember what you've found
• we want to search untill the end of domain so stop on the next / so add another / at the end: sed -n 's;\(http://[^/]*\)/' but we want to match the rest of the line after the domain so add .*
• now the match remembered in group 1 (\1) is the domain so replace matched line with stuff saved in group \1 and print: sed -n 's;\(http://[^/]*\)/.*;\1;p'

If you want to include backslash after the domain as well, then add one more backslash in the group to remember:

echo "http://www.suon.co.uk/product/1/7/3/" | sed -n 's;\(http://[^/]*/\).*;\1;p'

output:

http://www.suon.co.uk/

For those of you who still don't understand after reading @meda answer, here is my concise and complete explanation for this issue:

Let's say you have 2 Fragments, Fragment_A and Fragment_B which are auto-generated from the app. On the bottom part of your generated fragments, you're going to find this code:

public class Fragment_A extends Fragment {

    //rest of the code is omitted

    public interface OnFragmentInteractionListener {
        // TODO: Update argument type and name
        public void onFragmentInteraction(Uri uri);
    }
}

public class Fragment_B extends Fragment {

    //rest of the code is omitted

    public interface OnFragmentInteractionListener {
        // TODO: Update argument type and name
        public void onFragmentInteraction(Uri uri);
    }
}

To overcome the issue, you have to add onFragmentInteraction method into your activity, which in my case is named MainActivity2. After that, you need to implements all fragments in the MainActivity like this:

public class MainActivity2 extends ActionBarActivity
        implements Fragment_A.OnFragmentInteractionListener, 
                   Fragment_B.OnFragmentInteractionListener, 
                   NavigationDrawerFragment.NavigationDrawerCallbacks {
    //rest code is omitted

    @Override
    public void onFragmentInteraction(Uri uri){
        //you can leave it empty
    }
}

P.S.: In short, this method could be used for communicating between fragments. For those of you who want to know more about this method, please refer to this link.

This answer is specific for WordPress:

$base_dir = trailingslashit( get_stylesheet_directory() );
$base_url = trailingslashit( get_stylesheet_directory_uri() );

$media_dir = $base_dir . 'yourfolder/images/';
$media_url = $hase_url . 'yourfolder/images/';

$image_paths = glob( $media_dir . '*.jpg' );
$image_names = array();
$image_urls = array();

foreach ( $image_paths as $image ) {
    $image_names[] = str_replace( $media_dir, '', $image );
    $image_urls[] = str_replace( $media_dir, $media_url, $image );
}

// --- You now have:

// $image_paths ... list of absolute file paths 
// e.g. /path/to/wordpress/wp-content/uploads/yourfolder/images/sample.jpg

// $image_urls ... list of absolute file URLs 
// e.g. http://example.com/wp-content/uploads/yourfolder/images/sample.jpg

// $image_names ... list of filenames only
// e.g. sample.jpg

Here are some other settings that will give you images from other places than the child theme. Just replace the first 2 lines in above code with the version you need:

From Uploads directory:

// e.g. /path/to/wordpress/wp-content/uploads/yourfolder/images/sample.jpg
$upload_path = wp_upload_dir();
$base_dir = trailingslashit( $upload_path['basedir'] );
$base_url = trailingslashit( $upload_path['baseurl'] );

From Parent-Theme

// e.g. /path/to/wordpress/wp-content/themes/parent-theme/yourfolder/images/sample.jpg
$base_dir = trailingslashit( get_template_directory() );
$base_url = trailingslashit( get_template_directory_uri() );

From Child-Theme

// e.g. /path/to/wordpress/wp-content/themes/child-theme/yourfolder/images/sample.jpg
$base_dir = trailingslashit( get_stylesheet_directory() );
$base_url = trailingslashit( get_stylesheet_directory_uri() );

As far as I know, there are 2 standard ways you can do that.

1. @Input

Whenever the data in the parent changes, the child gets notified about this in the ngOnChanges method. The child can act on it. This is the standard way of interacting with a child.

Parent-Component
public inputToChild: Object;

Parent-HTML
<child [data]="inputToChild"> </child>       

Child-Component: @Input() data;

ngOnChanges(changes: { [property: string]: SimpleChange }){
   // Extract changes to the input property by its name
   let change: SimpleChange = changes['data']; 
// Whenever the data in the parent changes, this method gets triggered. You 
// can act on the changes here. You will have both the previous value and the 
// current value here.

2. Shared service concept

Creating a service and using an observable in the shared service. The child subscribes to it and whenever there is a change, the child will be notified. This is also a popular method. When you want to send something other than the data you pass as the input, this can be used.

SharedService
subject: Subject<Object>;

Parent-Component
constructor(sharedService: SharedService)
this.sharedService.subject.next(data);

Child-Component
constructor(sharedService: SharedService)
this.sharedService.subject.subscribe((data)=>{

// Whenever the parent emits using the next method, you can receive the data 
in here and act on it.})

Looks like opencv lib is pretty sensitive to parameters passed to the methods. The following code worked for me using opencv 4.3.0:

win_name = "visualization"  #  1. use var to specify window name everywhere
cv2.namedWindow(win_name, cv2.WINDOW_NORMAL)  #  2. use 'normal' flag
img = cv2.imread(filename)
h,w = img.shape[:2]  #  suits for image containing any amount of channels
h = int(h / resize_factor)  #  one must compute beforehand
w = int(w / resize_factor)  #  and convert to INT
cv2.resizeWindow(win_name, w, h)  #  use variables defined/computed BEFOREHAND
cv2.imshow(win_name, img)

In python, a constant is simply a variable with a name in all capitals, with words separated by the underscore character,

e.g

DAYS_IN_WEEK = 7

The value is mutable, as in you can change it. But given the rules for the name tell you is a constant, why would you? I mean, it is your program after all!

This is the approach taken throughout python. There is no private keyword for the same reason. Prefix the name with an underscore and you know it is intended to be private. Code can break the rule....just as a programmer could remove the private keyword anyway.

Python could have added a const keyword... but a programmer could remove keyword and then change the constant if they want to, but why do that? If you want to break the rule, you could change the rule anyway. But why bother to break the rule if the name makes the intention clear?

Maybe there is some unit test where it makes sense to apply a change to value? To see what happens for an 8 day week even though in the real world the number of days in the week cannot be changed. If the language stopped you making an exception if there is just this one case you need to break the rule...you would then have to stop declaring it as a constant, even though it still is a constant in the application, and there is just this one test case that sees what happens if it is changed.

The all upper case name tells you it is intended to be a constant. That is what is important. Not a language forcing constraints on code you have the power to change anyway.

That is the philosophy of python.

Easier way for me is to switch to R1C1 notation and just use R[-1]C1 and switch back when done.

Was having this issue testing long doubles, and alas, I came across a fix! You have to compile your project with -D__USE_MINGW_ANSI_STDIO:

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ gcc main.c

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ a.exe c=0.000000

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ gcc main.c -D__USE_MINGW_ANSI_STDIO

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ a.exe c=42.000000

Code:

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test
$ cat main.c
#include <stdio.h>

int main(int argc, char **argv)
{
   long double c=42;

   c/3;

   printf("c=%Lf\n",c);

   return 0;
}

It appears that SQL Server 2008 R2 can be downloaded with or without the management tools. I honestly have NO IDEA why someone would not want the management tools. But either way, the options are here:

http://www.microsoft.com/sqlserver/en/us/editions/express.aspx

and the one for 64 bit WITH the management tools (management studio) is here:

http://www.microsoft.com/sqlserver/en/us/editions/express.aspx

From the first link I presented, the 3rd and 4th include the management studio for 32 and 64 bit respectively.

typeperf "\processor(_total)\% processor time"

does work on Win7, you just need to extract the percent value yourself from the last quoted string.

A Swift 3 version for Xcode >6, where you can edit the inset value in Interface Builder / Storyboard.

import UIKit

@IBDesignable
class FormTextField: UITextField {

    @IBInspectable var inset: CGFloat = 0

    override func textRect(forBounds bounds: CGRect) -> CGRect {
        return bounds.insetBy(dx: inset, dy: inset)
    }

    override func editingRect(forBounds bounds: CGRect) -> CGRect {
        return textRect(forBounds: bounds)
    }

}

Had a similar problem (using NHibernate, so the ESCAPE keyword would have been very difficult) and solved it using the bracket characters. So your sample would become

WHERE ... LIKE '%aa[%]bb%'

If you need proof:

create table test (field nvarchar(100))
go
insert test values ('abcdef%hijklm')
insert test values ('abcdefghijklm')
go
select * from test where field like 'abcdef[%]hijklm'
go

As well as having then on a new line, you also need a space before and after the [, which is a special symbol in BASH.

#!/bin/bash
echo "start\n"
for f in *.jpg
do
  fname=$(basename "$f")
  echo "fname is $fname\n"
  fname="${filename%.*}"
  echo "fname is $fname\n"
  if [ $((fname %  2)) -eq 1 ]
  then
    echo "removing $fname\n"
    rm "$f"
  fi
done
