Sure:

try {
   throw new Exception('Something bad');
} catch (Exception $e) {
    // Do nothing
}

You might want to go have a read of the PHP documentation on Exceptions.

Different types to check the values exists

d = {"key1":"value1", "key2":"value2"}
"value10" in d.values() 
>> False

What if list of values

test = {'key1': ['value4', 'value5', 'value6'], 'key2': ['value9'], 'key3': ['value6']}
"value4" in [x for v in test.values() for x in v]
>>True

What if list of values with string values

test = {'key1': ['value4', 'value5', 'value6'], 'key2': ['value9'], 'key3': ['value6'], 'key5':'value10'}
values = test.values()
"value10" in [x for v in test.values() for x in v] or 'value10' in values
>>True

If your rename doesn't support -N, you can do something like this:

ls -1 --color=never -c | xargs rename -n 's/.*/our $i; sprintf("%04d.jpg", $i++)/e'

Edit To start with a given number, you can use the (somewhat ugly-looking) code below, just replace 123 with the number you want:

ls -1 --color=never  -c | xargs rename -n 's/.*/our $i; if(!$i) { $i=123; } sprintf("%04d.jpg", $i++)/e'

This lists files in order by creation time (newest first, add -r to ls to reverse sort), then sends this list of files to rename. Rename uses perl code in the regex to format and increment counter.

However, if you're dealing with JPEG images with EXIF information, I'd recommend exiftool

This is from the exiftool documentation, under "Renaming Examples"

   exiftool '-FileName<CreateDate' -d %Y%m%d_%H%M%S%%-c.%%e dir

   Rename all images in "dir" according to the "CreateDate" date and time, adding a copy number with leading '-' if the file already exists ("%-c"), and
   preserving the original file extension (%e).  Note the extra '%' necessary to escape the filename codes (%c and %e) in the date format string.

In order to simulate the issue that you are facing, I created the following sample using SSIS 2008 R2 with SQL Server 2008 R2 backend. The example is based on what I gathered from your question. This example doesn't provide a solution but it might help you to identify where the problem could be in your case.

Created a simple CSV file with two columns namely order number and order date. As you had mentioned in your question, values of both the columns are qualified with double quotes (") and also the lines end with Line Feed (\n) with the date being the last column. The below screenshot was taken using Notepad++, which can display the special characters in a file. LF in the screenshot denotes Line Feed.

Created a simple table named dbo.Destination in the SQL Server database to populate the CSV file data using SSIS package. Create script for the table is given below.

CREATE TABLE [dbo].[Destination](
    [OrderNumber] [varchar](50) NULL,
    [OrderDate] [date] NULL
) ON [PRIMARY]
GO

On the SSIS package, I created two connection managers. SQLServer was created using the OLE DB Connection to connect to the SQL Server database. FlatFile is a flat file connection manager.

Flat file connection manager was configured to read the CSV file and the settings are shown below. The red arrows indicate the changes made.

Provided a name to the flat file connection manager. Browsed to the location of the CSV file and selected the file path. Entered the double quote (") as the text qualifier. Changed the Header row delimiter from {CR}{LF} to {LF}. This header row delimiter change also reflects on the Columns section.

No changes were made in the Columns section.

Changed the column name from Column0 to OrderNumber.

Changed the column name from Column1 to OrderDate and also changed the data type to date [DT_DATE]

Preview of the data within the flat file connection manager looks good.

On the Control Flow tab of the SSIS package, placed a Data Flow Task.

Within the Data Flow Task, placed a Flat File Source and an OLE DB Destination.

The Flat File Source was configured to read the CSV file data using the FlatFile connection manager. Below three screenshots show how the flat file source component was configured.

The OLE DB Destination component was configured to accept the data from Flat File Source and insert it into SQL Server database table named dbo.Destination. Below three screenshots show how the OLE DB Destination component was configured.

Using the steps mentioned in the below 5 screenshots, I added a data viewer on the flow between the Flat File Source and OLE DB Destination.

Before running the package, I verified the initial data present in the table. It is currently empty because I created this using the script provided at the beginning of this post.

Executed the package and the package execution temporarily paused to display the data flowing from Flat File Source to OLE DB Destination in the data viewer. I clicked on the run button to proceed with the execution.

The package executed successfully.

Flat file source data was inserted successfully into the table dbo.Destination.

Here is the layout of the table dbo.Destination. As you can see, the field OrderDate is of data type date and the package still continued to insert the data correctly.

This post even though is not a solution. Hopefully helps you to find out where the problem could be in your scenario.

public static boolean CheckIsDataAlreadyInDBorNot(String TableName,
        String dbfield, String fieldValue) {
    SQLiteDatabase sqldb = EGLifeStyleApplication.sqLiteDatabase;
    String Query = "Select * from " + TableName + " where " + dbfield + " = " + fieldValue;
    Cursor cursor = sqldb.rawQuery(Query, null);
        if(cursor.getCount() <= 0){
            cursor.close();
            return false;
        }
    cursor.close();
    return true;
}

I hope this is useful to you... This function returns true if record already exists in db. Otherwise returns false.

I think you're asking how to compute the mean of a variable in a data frame, given the name of the column. There are two typical approaches to doing this, one indexing with [[ and the other indexing with [:

data(iris)
mean(iris[["Petal.Length"]])
# [1] 3.758
mean(iris[,"Petal.Length"])
# [1] 3.758
mean(iris[["Sepal.Width"]])
# [1] 3.057333
mean(iris[,"Sepal.Width"])
# [1] 3.057333

Your array is of byte primitives, but you're trying to call a method on them.

You don't need to do anything explicit to convert a byte to an int, just:

int i=rno[0];

...since it's not a downcast.

Note that the default behavior of byte-to-int conversion is to preserve the sign of the value (remember byte is a signed type in Java). So for instance:

byte b1 = -100;
int i1 = b1;
System.out.println(i1); // -100

If you were thinking of the byte as unsigned (156) rather than signed (-100), as of Java 8 there's Byte.toUnsignedInt:

byte b2 = -100; // Or `= (byte)156;`
int = Byte.toUnsignedInt(b2);
System.out.println(i2); // 156

Prior to Java 8, to get the equivalent value in the int you'd need to mask off the sign bits:

byte b2 = -100; // Or `= (byte)156;`
int i2 = (b2 & 0xFF);
System.out.println(i2); // 156

Just for completeness #1: If you did want to use the various methods of Byte for some reason (you don't need to here), you could use a boxing conversion:

Byte b = rno[0]; // Boxing conversion converts `byte` to `Byte`
int i = b.intValue();

Or the Byte constructor:

Byte b = new Byte(rno[0]);
int i = b.intValue();

But again, you don't need that here.

Just for completeness #2: If it were a downcast (e.g., if you were trying to convert an int to a byte), all you need is a cast:

int i;
byte b;

i = 5;
b = (byte)i;

This assures the compiler that you know it's a downcast, so you don't get the "Possible loss of precision" error.

The easiest way to match both

^\([0-9]{3}\)[0-9]{3}-[0-9]{4}$

and

^[0-9]{3}-[0-9]{3}-[0-9]{4}$

is to use alternation ((...|...)): specify them as two mostly-separate options:

^(\([0-9]{3}\)|[0-9]{3}-)[0-9]{3}-[0-9]{4}$

By the way, when Americans put the area code in parentheses, we actually put a space after that; for example, I'd write (123) 123-1234, not (123)123-1234. So you might want to write:

^(\([0-9]{3}\) |[0-9]{3}-)[0-9]{3}-[0-9]{4}$

(Though it's probably best to explicitly demonstrate the format that you expect phone numbers to be in.)

Try adding the following to your GridLayout spec. That should work.

android:useDefaultMargins="true"

If you have a lot of binary data to read, you might want to consider the struct module. It is documented as converting "between C and Python types", but of course, bytes are bytes, and whether those were created as C types does not matter. For example, if your binary data contains two 2-byte integers and one 4-byte integer, you can read them as follows (example taken from struct documentation):

>>> struct.unpack('hhl', b'\x00\x01\x00\x02\x00\x00\x00\x03')
(1, 2, 3)

You might find this more convenient, faster, or both, than explicitly looping over the content of a file.

simple way :

   -(void) viewDidLoad {
   self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage       imageNamed:@"background.png"]];
    [super viewDidLoad];
    }

Put the date in single quotes and move the parenthesis (after the 'yes') to the end:

INSERT INTO custorder 
  VALUES ('Kevin', 'yes' , STR_TO_DATE('1-01-2012', '%d-%m-%Y') ) ;
                        ^                                     ^
---parenthesis removed--|                and added here ------|

But you can always use dates without STR_TO_DATE() function, just use the (Y-m-d) '20120101' or '2012-01-01' format. Check the MySQL docs: Date and Time Literals

INSERT INTO custorder 
  VALUES ('Kevin', 'yes', '2012-01-01') ;

I fixed this issue, this way:

1. Stop the Server
2. Remove the previous Deploy that You did
3. Clean it
4. Deploy it again

HashMap<String, String> hashMap = new HashMap<>();
String[] stringValues= new String[hashMap.values().size()];
hashMap.values().toArray(stringValues);

It is crude, but you can open up the Javascript console in Chrome (Ctrl+Shift+J) and paste the text contents of the *.js file and hit Enter.

A variant of Peter's example, that demonstrates a way this could be used to generate all numbers between 0 and 99.

with digits as (
  select mod(rownum,10) as num 
  from   dual 
  connect by rownum <= 10
)
select a.num*10+b.num as num 
from   digits a
       ,digits b
order by num
;

Something like this becomes useful when you are doing batch identifier assignment, and looking for the items that have not yet been assigned.

For example, if you are selling bingo tickets, you may want to assign batches of 100 floor staff (guess how i used to fund raise for sports). As they sell a batch, they are given the next batch in sequence. However, people purchasing the tickets can select to purchase any tickets from the batch. The question may be asked, "what tickets have been sold".

In this case, we only have a partial, random, list of tickets that were returned within the given batch, and require a complete list of all possibilities to determine which we don't have.

with range as (
  select mod(rownum,100) as num 
  from   dual 
  connect by rownum <= 100
),
AllPossible as (
  select a.num*100+b.num as TicketNum
  from   batches a
         ,range b
  order by num
)
select TicketNum as TicketsSold
from   AllPossible
where  AllPossible.Ticket not in (select TicketNum from TicketsReturned)
;

Excuse the use of key words, I changed some variable names from a real world example.

... To demonstrate why something like this would be useful

Change column position:

ALTER TABLE Employees 
   CHANGE empName empName VARCHAR(50) NOT NULL AFTER department;

If you need to move it to the first position you have to use term FIRST at the end of ALTER TABLE CHANGE [COLUMN] query:

ALTER TABLE UserOrder 
   CHANGE order_id order_id INT(11) NOT NULL FIRST;

I had this issue myself, and I wanted to both be able to set the width, and have it update on rotate and allow the user to scale and zoom the page (the current answer provides the first but prevents the later as a side-effect).. so I came up with a fix that keeps the view width correct for the orientation, but still allows for zooming, though it is not super straight forward.

First, add the following Javascript to the webpage you are displaying:

 <script type='text/javascript'>
 function setViewPortWidth(width) {
  var metatags = document.getElementsByTagName('meta');
  for(cnt = 0; cnt < metatags.length; cnt++) { 
   var element = metatags[cnt];
   if(element.getAttribute('name') == 'viewport') {

    element.setAttribute('content','width = '+width+'; maximum-scale = 5; user-scalable = yes');
    document.body.style['max-width'] = width+'px';
   }
  }
 }
 </script>

Then in your - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation method, add:

float availableWidth = [EmailVC webViewWidth];
NSString *stringJS;

stringJS = [NSString stringWithFormat:@"document.body.offsetWidth"];
float documentWidth = [[_webView stringByEvaluatingJavaScriptFromString:stringJS] floatValue];

if(documentWidth > availableWidth) return; // Don't perform if the document width is larger then available (allow auto-scale)

// Function setViewPortWidth defined in EmailBodyProtocolHandler prepend
stringJS = [NSString stringWithFormat:@"setViewPortWidth(%f);",availableWidth];
[_webView stringByEvaluatingJavaScriptFromString:stringJS];

Additional Tweaking can be done by modifying more of the viewportal content settings:

http://www.htmlgoodies.com/beyond/webmaster/toolbox/article.php/3889591/Detect-and-Set-the-iPhone--iPads-Viewport-Orientation-Using-JavaScript-CSS-and-Meta-Tags.htm

Also, I understand you can put a JS listener for onresize or something like to trigger the rescaling, but this worked for me as I'm doing it from Cocoa Touch UI frameworks.

Hope this helps someone :)

I have posted a new post about how to build an Android NDK application with OpenCV included using Android Studio and Gradle. More information can be seen here, I have summarized two methods:

(1) run ndk-build within Gradle task

sourceSets.main.jni.srcDirs = []

task ndkBuild(type: Exec, description: 'Compile JNI source via NDK') {
    ndkDir = project.plugins.findPlugin('com.android.application').getNdkFolder()
    commandLine "$ndkDir/ndk-build",
            'NDK_PROJECT_PATH=build/intermediates/ndk',
            'NDK_LIBS_OUT=src/main/jniLibs',
            'APP_BUILD_SCRIPT=src/main/jni/Android.mk',
            'NDK_APPLICATION_MK=src/main/jni/Application.mk'
}

tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn ndkBuild
}

(2) run ndk-build with an external tool

Parameters: NDK_PROJECT_PATH=$ModuleFileDir$/build/intermediates/ndk NDK_LIBS_OUT=$ModuleFileDir$/src/main/jniLibs NDK_APPLICATION_MK=$ModuleFileDir$/src/main/jni/Application.mk APP_BUILD_SCRIPT=$ModuleFileDir$/src/main/jni/Android.mk V=1

You missed a parenthesis.

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

Whenever you want to use ant thread safe version of ant collection object,take help of java.util.concurrent.* package. It has almost all concurrent version of unsynchronized collection objects. eg: for ArrayList, you have java.util.concurrent.CopyOnWriteArrayList

You can do Collections.synchronizedCollection(any collection object),but remember this classical synchr. technique is expensive and comes with performence overhead. java.util.concurrent.* package is less expensive and manage the performance in better way by using mechanisms like

copy-on-write,compare-and-swap,Lock,snapshot iterators,etc.

So,Prefer something from java.util.concurrent.* package

I think this is what you're looking for. NEW_BAL is the sum of QTYs subtracted from the balance:

SELECT   master_table.ORDERNO,
         master_table.ITEM,
         SUM(master_table.QTY),
         stock_bal.BAL_QTY,
         (stock_bal.BAL_QTY - SUM(master_table.QTY)) AS NEW_BAL
FROM     master_table INNER JOIN
         stock_bal ON master_bal.ITEM = stock_bal.ITEM
GROUP BY master_table.ORDERNO,
         master_table.ITEM

If you want to update the item balance with the new balance, use the following:

UPDATE stock_bal
SET    BAL_QTY = BAL_QTY - (SELECT   SUM(QTY)
                            FROM     master_table
                            GROUP BY master_table.ORDERNO,
                                     master_table.ITEM)

This assumes you posted the subtraction backward; it subtracts the quantities in the order from the balance, which makes the most sense without knowing more about your tables. Just swap those two to change it if I was wrong:

(SUM(master_table.QTY) - stock_bal.BAL_QTY) AS NEW_BAL

WordUtils.capitalizeFully(str) from apache commons-lang has the exact semantics as required.

The solution is to put an N in front of both the type and the SQL string to indicate it is a double-byte character string:

SET @SQL = N'SELECT TOP 1 * FROM sys.tables' 
EXECUTE sp_executesql @SQL

When you say "is there an easier way to... trust this cert", that's exactly what you're doing by adding the cert to your Java trust store. And this is very, very easy to do, and there's nothing you need to do within your client app to get that trust store recognized or utilized.

On your client machine, find where your cacerts file is (that's your default Java trust store, and is, by default, located at <java-home>/lib/security/certs/cacerts.

Then, type the following:

keytool -import -alias <Name for the cert> -file <the .cer file> -keystore <path to cacerts>

That will import the cert into your trust store, and after this, your client app will be able to connect to your Grizzly HTTPS server without issue.

If you don't want to import the cert into your default trust store -- i.e., you just want it to be available to this one client app, but not to anything else you run on your JVM on that machine -- then you can create a new trust store just for your app. Instead of passing keytool the path to the existing, default cacerts file, pass keytool the path to your new trust store file:

keytool -import -alias <Name for the cert> -file <the .cer file> -keystore <path to new trust store>

You'll be asked to set and verify a new password for the trust store file. Then, when you start your client app, start it with the following parameters:

java -Djavax.net.ssl.trustStore=<path to new trust store> -Djavax.net.ssl.trustStorePassword=<trust store password>

Easy cheesy, really.

varbinary(max) is the way to go (introduced in SQL Server 2005)

Here is another direct-access implementation:

head="$(cat ".git/HEAD")"
while [ "$head" != "${head#ref: }" ]; do
  head="$(cat ".git/${head#ref: }")"
done

This also works over http which is useful for local package archives (I know: for public web sites it's not recommended to make the .git directory accessable):

head="$(curl -s "$baseurl/.git/HEAD")"
while [ "$head" != "${head#ref: }" ]; do
  head="$(curl -s "$baseurl/.git/${head#ref: }")"
done

The Google reCAPTCHA version 2 ASP.Net allows validating the Captcha response on the client side using its Callback functions. In this example, the Google new reCAPTCHA will be validated using ASP.Net RequiredField Validator.

                    url: "Demo.aspx/VerifyCaptcha",
                    data: "{response: '" + response + "'}",
                    contentType: "application/json; charset=utf-8",

                            $("[id*=rfvCaptcha]").show();
                            var error = captchaResponse["error-codes"][0];

It is a syntax sugar for faster query writing. Its implementation in pseudocode:

def filter_by(self, **kwargs):
    return self.filter(sql.and_(**kwargs))

For AND you can simply write:

session.query(db.users).filter_by(name='Joe', surname='Dodson')

btw

session.query(db.users).filter(or_(db.users.name=='Ryan', db.users.country=='England'))

can be written as

session.query(db.users).filter((db.users.name=='Ryan') | (db.users.country=='England'))

Also you can get object directly by PK via get method:

Users.query.get(123)
# And even by a composite PK
Users.query.get(123, 321)

When using get case its important that object can be returned without database request from identity map which can be used as cache(associated with transaction)

• First line : array created.
• Third line loop started from j = 1 to j = 28123
• Fourth line you give the variable x value (0) each time the loop is accessed.
• Fifth line you put the value of j in the index 0.
• Sixth line you do increment to the value x by 1.(but it will be reset to 0 at line 4)

You can use the six library to support both Python 2 and 3:

import six
if isinstance(value, six.string_types):
    handle_string(value)

Merge them in two steps, df1 and df2 first, and then the result of that to df3.

add the permission to the manifest for reading logs

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

Let's just say you have 3 buttons:

<input type="button" disabled="disabled" value="hello world">
<input type="button" disabled value="hello world">
<input type="button" value="hello world">

To style the disabled button you can use the following css:

input[type="button"]:disabled{
    color:#000;
}

This will only affect the button which is disabled.

To stop the color changing when hovering you can use this too:

input[type="button"]:disabled:hover{
    color:#000;
}

You can also avoid this by using a css-reset.

First, Set :
ALTER TABLE person ALTER COLUMN phone DROP NOT NULL;

Go to the Declaration of the desired object and mark it Shared.

Use XStream toXML/fromXML in memory. Extremely fast and has been around for a long time and is going strong. Objects don't need to be Serializable and you don't have use reflection (although XStream does). XStream can discern variables that point to the same object and not accidentally make two full copies of the instance. A lot of details like that have been hammered out over the years. I've used it for a number of years and it is a go to. It's about as easy to use as you can imagine.

new XStream().toXML(myObj)

or

new XStream().fromXML(myXML)

To clone,

new XStream().fromXML(new XStream().toXML(myObj))

More succinctly:

XStream x = new XStream();
Object myClone = x.fromXML(x.toXML(myObj));

$('#form-btn').click(function () {

      var name = $(this).attr('name');
      rules[name] = {};
      messages[name] = {};

      rules[name] = {required: true}; // set required true against every name
//apply more rules, you can also apply custom rules & messages
      if (name === "email") {
         rules[name].email = true;
         //messages[name].email = "Please provide valid email";
      }
      else if(name==='url'){
        rules[name].required = false; // url filed is not required
//add other rules & messages
      }
   });
//submit form and use above created global rules & messages array
   $('#formId').submit(function (e) {
            e.preventDefault();
        }).validate({
            rules: rules,

            submitHandler: function (form) {

Initially I used object in useState, but then I moved to useReducer hook for complex cases. I felt a performance improvement when I refactored the code.

useReducer is usually preferable to useState when you have complex state logic that involves multiple sub-values or when the next state depends on the previous one.

useReducer React docs

I already implemented such hook for my own use:

/**
 * Same as useObjectState but uses useReducer instead of useState
 *  (better performance for complex cases)
 * @param {*} PropsWithDefaultValues object with all needed props 
 * and their initial value
 * @returns [state, setProp] state - the state object, setProp - dispatch 
 * changes one (given prop name & prop value) or multiple props (given an 
 * object { prop: value, ...}) in object state
 */
export function useObjectReducer(PropsWithDefaultValues) {
  const [state, dispatch] = useReducer(reducer, PropsWithDefaultValues);

  //newFieldsVal={[field_name]: [field_value], ...}
  function reducer(state, newFieldsVal) {
    return { ...state, ...newFieldsVal };
  }

  return [
    state,
    (newFieldsVal, newVal) => {
      if (typeof newVal !== "undefined") {
        const tmp = {};
        tmp[newFieldsVal] = newVal;
        dispatch(tmp);
      } else {
        dispatch(newFieldsVal);
      }
    },
  ];
}

The method

setParams() 

like

httpget.getParams().setParameter("http.socket.timeout", new Integer(5000));

only adds HttpProtocol parameters.

To execute the httpGet you should append your parameters to the url manually

HttpGet myGet = new HttpGet("http://foo.com/someservlet?param1=foo&param2=bar");

or use the post request the difference between get and post requests are explained here, if you are interested

Sven has shown how to use the class gaussian_kde from Scipy, but you will notice that it doesn't look quite like what you generated with R. This is because gaussian_kde tries to infer the bandwidth automatically. You can play with the bandwidth in a way by changing the function covariance_factor of the gaussian_kde class. First, here is what you get without changing that function:

However, if I use the following code:

import matplotlib.pyplot as plt
import numpy as np
from scipy.stats import gaussian_kde
data = [1.5]*7 + [2.5]*2 + [3.5]*8 + [4.5]*3 + [5.5]*1 + [6.5]*8
density = gaussian_kde(data)
xs = np.linspace(0,8,200)
density.covariance_factor = lambda : .25
density._compute_covariance()
plt.plot(xs,density(xs))
plt.show()

I get

which is pretty close to what you are getting from R. What have I done? gaussian_kde uses a changable function, covariance_factor to calculate its bandwidth. Before changing the function, the value returned by covariance_factor for this data was about .5. Lowering this lowered the bandwidth. I had to call _compute_covariance after changing that function so that all of the factors would be calculated correctly. It isn't an exact correspondence with the bw parameter from R, but hopefully it helps you get in the right direction.

I believe because cases must be constant values, the switch statement does the equivelent of a goto, so based on the value of the variable it jumps to the right case, whereas in the if/then statement it must evaluate each expression.

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.

Tips from 2020:

From Flask 1.0, it defaults to enable multiple threads (source), you don't need to do anything, just upgrade it with:

$ pip install -U flask

If you are using flask run instead of app.run() with older versions, you can control the threaded behavior with a command option (--with-threads/--without-threads):

$ flask run --with-threads

It's same as app.run(threaded=True)

java [any other JVM options you need to give it] -jar foo.jar

You can change the default with an alter table set default charset but that won't change the charset of the existing columns. To change that you need to use a alter table modify column.

Changing the charset of a column only means that it will be able to store a wider range of characters. Your application talks to the db using the mysql client so you may need to change the client encoding as well.

This could be solved without VBA by the following technique.

In this example I am counting all the threes (3) in the range A:A of the sheets Page M904, Page M905 and Page M906.

List all the sheet names in a single continuous range like in the following example. Here listed in the range D3:D5.

Then by having the lookup value in cell B2, the result can be found in cell B4 by using the following formula:

=SUMPRODUCT(COUNTIF(INDIRECT("'"&D3:D5&"'!A:A"), B2))

A directive which adds another directive to the same element:

Similar answers:

• How to get ng-class with $dirty working in a directive?
• creating a new directive with angularjs

Here is a plunker: http://plnkr.co/edit/ziU8d826WF6SwQllHHQq?p=preview

app.directive("myDir", function($compile) {
  return {
    priority:1001, // compiles first
    terminal:true, // prevent lower priority directives to compile after it
    compile: function(el) {
      el.removeAttr('my-dir'); // necessary to avoid infinite compile loop
      el.attr('ng-click', 'fxn()');
      var fn = $compile(el);
      return function(scope){
        fn(scope);
      };
    }
  };
});

Much cleaner solution - not to use ngClick at all:

A plunker: http://plnkr.co/edit/jY10enUVm31BwvLkDIAO?p=preview

app.directive("myDir", function($parse) {
  return {
    compile: function(tElm,tAttrs){
      var exp = $parse('fxn()');
      return function (scope,elm){
        elm.bind('click',function(){
          exp(scope);
        });  
      };
    }
  };
});

As of Swift 3 / 4 / 5, this is done as follows.

To add a new element to the end of an Array.

anArray.append("This String")

To append a different Array to the end of your Array.

anArray += ["Moar", "Strings"]
anArray.append(contentsOf: ["Moar", "Strings"])

To insert a new element into your Array.

anArray.insert("This String", at: 0)

To insert the contents of a different Array into your Array.

anArray.insert(contentsOf: ["Moar", "Strings"], at: 0)

More information can be found in the "Collection Types" chapter of "The Swift Programming Language", starting on page 110.

NodeJS answer:

In case you wanted to do it with NodeJS: make a GET to JSON endpoint with Authorization header and get a Promise back:

First

npm install --save request request-promise

(see on npm) and then in your .js file:

var requestPromise = require('request-promise');

var user = 'user';
var password = 'password';

var base64encodedData = Buffer.from(user + ':' + password).toString('base64');

requestPromise.get({
  uri: 'https://example.org/whatever',
  headers: {
    'Authorization': 'Basic ' + base64encodedData
  },
  json: true
})
.then(function ok(jsonData) {
  console.dir(jsonData);
})
.catch(function fail(error) {
  // handle error
});

If the users enter an incorrect value, apply a 1px red color border to the input field:

document.getElementById('fName').style.border ="1px solid red";

If the user enters a correct value, remove the border from the input field:

document.getElementById('fName').style.border ="";

The div elements are block elements, so by default they take upp the full available width.

One way is to turn them into inline elements:

.label, .text { display: inline; }

This will have the same effect as using span elements instead of div elements.

Another way is to float the elements:

.label, .text { float: left; }

This will change how the width of the elements is decided, so that thwy will only be as wide as their content. It will also make the elements float beside each other, similar to how images flow beside each other.

You can also consider changing the elements. The div element is intended for document divisions, I usually use a label and a span element for a construct like this:

<label>My Label:</label>
<span>My text</span>

int arr[5] = {4, 1, 3, 2, 6};
vector<int> vec;
int i =0;
int no_to_be_found;

cin >> no_to_be_found;

while(i != 4)
{
    vec.push_back(arr[i]);
    i++;
}

cout << find(vec.begin(),vec.end(),no_to_be_found) - vec.begin();

For lists, use enumerate

for field, possible_values in enumerate(fields):
    print(field, possible_values)

iteritems will not work for list objects

I had similar problem when i was trying to work with coco-ssd. I think this problem is caused because of the version. I changed version of tfjs to 0.9.0 and coco-ssd version to 1.1.0 and it worked for me. (you can search for posenet versions on : https://www.jsdelivr.com/package/npm/@tensorflow-models/posenet)

<!-- Load TensorFlow.js-->

Simply add a -h after adding your credentials using a -u -p, and it will run with elevated privileges.

Are you running the Web API app in a virtual directory or an application?

For example: I had the same issue when I moved my project to my local IIS under the Default Web Site > SampleWebAPI. I believe this is due to the change in the URL routing as follows:

Original: localhost:3092/api/values
Moved: localhost/SampleWebAPI/api/values

If you move the Web API project to it's own website running on a different port it seems to work.

Additional note: I had further complicated the issue by adding api as the alias of an application within my website which caused the effective URL to be:

localhost:81/api/api/values - noticed this after moving the website to it's own website

Therefore, because I wanted to maintain a separation between my website and the web api mvc project site, I changed the routing rules in global.asax for the Web API "DefaultAPI" from api/{controller}/{id} to {controller}/{id} and the ASP.NET MVC one Default from {controller}/{id} to info/{controller}/{id}.

OPcache replaces APC

Because OPcache is designed to replace the APC module, it is not possible to run them in parallel in PHP. This is fine for caching PHP opcode as neither affects how you write code.

However it means that if you are currently using APC to store other data (through the apc_store() function) you will not be able to do that if you decide to use OPCache.

You will need to use another library such as either APCu or Yac which both store data in shared PHP memory, or switch to use something like memcached, which stores data in memory in a separate process to PHP.

Also, OPcache has no equivalent of the upload progress meter present in APC. Instead you should use the Session Upload Progress.

Settings for OPcache

The documentation for OPcache can be found here with all of the configuration options listed here. The recommended settings are:

; Sets how much memory to use
opcache.memory_consumption=128

;Sets how much memory should be used by OPcache for storing internal strings 
;(e.g. classnames and the files they are contained in)
opcache.interned_strings_buffer=8

; The maximum number of files OPcache will cache
opcache.max_accelerated_files=4000

;How often (in seconds) to check file timestamps for changes to the shared
;memory storage allocation.
opcache.revalidate_freq=60

;If enabled, a fast shutdown sequence is used for the accelerated code
;The fast shutdown sequence doesn't free each allocated block, but lets
;the Zend Engine Memory Manager do the work.
opcache.fast_shutdown=1

;Enables the OPcache for the CLI version of PHP.
opcache.enable_cli=1

If you use any library or code that uses code annotations you must enable save comments:

opcache.save_comments=1

If disabled, all PHPDoc comments are dropped from the code to reduce the size of the optimized code. Disabling "Doc Comments" may break some existing applications and frameworks (e.g. Doctrine, ZF2, PHPUnit)

In my opinion, utilizing Object.freeze allows for a DRYer and more declarative style. My preferred pattern is:

./lib/constants.js

module.exports = Object.freeze({
    MY_CONSTANT: 'some value',
    ANOTHER_CONSTANT: 'another value'
});

./lib/some-module.js

var constants = require('./constants');

console.log(constants.MY_CONSTANT); // 'some value'

constants.MY_CONSTANT = 'some other value';

console.log(constants.MY_CONSTANT); // 'some value'

Outdated Performance Warning

The following issue was fixed in v8 in Jan 2014 and is no longer relevant to most developers:

Be aware that both setting writable to false and using Object.freeze have a massive performance penalty in v8 - https://bugs.chromium.org/p/v8/issues/detail?id=1858 and http://jsperf.com/performance-frozen-object

each JSF component renders itself out to HTML and has complete control over what HTML it produces. There are many tricks that can be used by JSF, and exactly which of those tricks will be used depends on the JSF implementation you are using.

• Ensure that every from input has a totaly unique name, so that when the form gets submitted back to to component tree that rendered it, it is easy to tell where each component can read its value form.
• The JSF component can generate javascript that submitts back to the serer, the generated javascript knows where each component is bound too, because it was generated by the component.

• For things like hlink you can include binding information in the url as query params or as part of the url itself or as matrx parameters. for examples.

  http:..../somelink?componentId=123 would allow jsf to look in the component tree to see that link 123 was clicked. or it could e htp:..../jsf;LinkId=123

The easiest way to answer this question is to create a JSF page with only one link, then examine the html output it produces. That way you will know exactly how this happens using the version of JSF that you are using.

ALTER TABLE MyTable MODIFY Col3 varchar(20) NULL;

Do:

My answer is very similar to the one from @biscoop, but I am going to elaborate a bit as it may apply to the question or to other people.

I had a .xls that was an extraction from one of our webapps. The Excel connection would not work (error message: "no tables or views could be loaded"). As a side note, when opening the file, there would be a warning stating that the file was from an online source and that the content needed activation.

I tried to save the same file as an .xlsx and it worked. I tried to save the same file with another name as an .xls and it worked too. So as a last test I only opened the source .xls file, clicking save and the connection worked.

Short answer: just try and see if opening the file and saving does the trick.

I wanted a more permanent and quicker way. Because I tend to forget to add extra lines before writing my actual Update/Insert queries.

I did it by checking SET IMPLICIT_TRANSACTIONS check-box from Options. To navigate to Options Select Tools>Options>Query Execution>SQL Server>ANSI in your Microsoft SQL Server Management Studio.

Just make sure to execute commit or rollback after you are done executing your queries. Otherwise, the table you would have run the query will be locked for others.

You just have to push the tag after you run the git tag 2.0 command.

So just do git push --tags now.

By using typed arrays, you can store arrays of these types:

• Int8
• Uint8
• Int16
• Uint16
• Int32
• Uint32
• Float32
• Float64

For example:

?var array = new Uint8Array(100);
array[42] = 10;
alert(array[42]);?

See it in action here.

Addressing Vicky Ronnen's head up, considering the following code:

function use_global
{
    eval "$1='changed using a global var'"
}

function capture_output
{
    echo "always changed"
}

function test_inside_a_func
{
    local _myvar='local starting value'
    echo "3. $_myvar"

    use_global '_myvar'
    echo "4. $_myvar"

    _myvar=$( capture_output )
    echo "5. $_myvar"
}

function only_difference
{
    local _myvar='local starting value'
    echo "7. $_myvar"

    local use_global '_myvar'
    echo "8. $_myvar"

    local _myvar=$( capture_output )
    echo "9. $_myvar"
}

declare myvar='global starting value'
echo "0. $myvar"

use_global 'myvar'
echo "1. $myvar"

myvar=$( capture_output )
echo "2. $myvar"

test_inside_a_func
echo "6. $_myvar" # this was local inside the above function

only_difference

will give

0. global starting value
1. changed using a global var
2. always changed
3. local starting value
4. changed using a global var
5. always changed
6. 
7. local starting value
8. local starting value
9. always changed

Maybe the normal scenario is to use the syntax used in the test_inside_a_func function, thus you can use both methods in the majority of cases, although capturing the output is the safer method always working in any situation, mimicking the returning value from a function that you can find in other languages, as Vicky Ronnen correctly pointed out.

I am pretty sure that what you are looking for is called --find-links option.

You can do

pip install mypackage --no-index --find-links file:///srv/pkg/mypackage

Serhii's suggestion works and here is some more detail.

If you look in your installation's bin directory you will see catalina.sh or .bat scripts. If you look in these you will see that they run a setenv.sh or setenv.bat script respectively, if it exists, to set environment variables. The relevant environment variables are described in the comments at the top of catalina.sh/bat. To use them create, for example, a file $CATALINA_HOME/bin/setenv.sh with contents

export JAVA_OPTS="-server -Xmx512m"

For Windows you will need, in setenv.bat, something like

set JAVA_OPTS=-server -Xmx768m

Hope this helps, Glenn

I know angular has hierarchical injectors like Thierry said.

But I have another option here in case you find a use-case where you don't really want to inject it at the parent.

We can achieve that by creating an instance of the service, and on provide always return that.

import { provide, Injectable } from '@angular/core';
import { Http } from '@angular/core'; //Dummy example of dependencies

@Injectable()
export class YourService {
  private static instance: YourService = null;

  // Return the instance of the service
  public static getInstance(http: Http): YourService {
    if (YourService.instance === null) {
       YourService.instance = new YourService(http);
    }
    return YourService.instance;
  }

  constructor(private http: Http) {}
}

export const YOUR_SERVICE_PROVIDER = [
  provide(YourService, {
    deps: [Http],
    useFactory: (http: Http): YourService => {
      return YourService.getInstance(http);
    }
  })
];

And then on your component you use your custom provide method.

@Component({
  providers: [YOUR_SERVICE_PROVIDER]
})

And you should have a singleton service without depending on the hierarchical injectors.

I'm not saying this is a better way, is just in case someone has a problem where hierarchical injectors aren't possible.

simply add android:indeterminateTint="@color/colorPrimary" to your progressBar

Example:

<ProgressBar
    android:id="@+id/progressBar"
    style="?android:attr/progressBarStyle"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:indeterminateTint="@color/colorPrimary"/>

in case of progressBarStyleHorizontal change android:progressTint="@color/colorPrimary"

Example:

 <ProgressBar
    android:id="@+id/progressBar"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:progress="50"
    android:progressTint="@color/colorPrimary" />

Git- Git is a version control software that you install on your local system. For an individual working on a project alone, Git proves to be excellent software.

GitHub- As mentioned earlier, Git is a version control system that tracks code changes, while GitHub is a web-based Git version control repository hosting service. It provides all of the distributed version control and source code management (SCM) functionalities of Git while topping it with a few of its own features.

On top of everything that's been said (

), which is correct, TFS isn't just a VCS. One major feature that TFS provides is natively integrated bug tracking functionality. Changesets are linked to issues and could be tracked. Various policies for check-ins are supported, as well as integration with Windows domain, which is what people who run TFS have. Tightly integrated GUI with Visual Studio is another selling point, which appeals to less than average mouse and click developer and his manager.

Hence comparing Git to TFS isn't a proper question to ask. Correct, though impractical, question is to compare Git with just VCS functionality of TFS. At that, Git blows TFS out of the water. However, any serious team needs other tools and this is where TFS provides one stop destination.

Windows XP has the Windows Firewall which can interfere with network traffic if not configured properly. You can turn off the Windows Firewall, if you have administrator privileges, by accessing the Windows Firewall applet through the Control Panel. If your application works with the Windows Firewall turned off then the problem is probably due to the settings of the firewall.

We have an application which runs on multiple PCs communicating using UDP/IP and we have been doing experiments so that the application can run on a PC with a user who does not have administrator privileges. In order for our application to communicate between multiple PCs we have had to use an administrator account to modify the Windows Firewall settings.

In our application, one PC is designated as the server and the others are clients in a server/client group and there may be several groups on the same subnet.

The first change was to use the functionality of the Exceptions tab of the Windows Firewall applet to create an exception for the port that we use for communication.

We are using host name lookup so that the clients can locate their assigned server by using the computer name which is composed of a mnemonic prefix with a dash followed by an assigned terminal number (for instance SERVER100-1). This allows several servers with their assigned clients to coexist on the same subnet. The client uses its prefix to generate the computer name for the assigned server and to then use host name lookup to discover the IP address of the assigned server.

What we found is that the host name lookup using the computer name (assigned through the Computer Name tab of the System Properties dialog) would not work unless the server PC's Windows Firewall had the File and Printer Sharing Service port enabled.

So we had to make two changes: (1) setup an exception for the port we used for communication and (2) enable File and Printer Service in the Exceptions tab to allow for the host name lookup.

It sounds like you're trying to link with your resulting object file with gcc instead of g++:

Note that programs using C++ object files must always be linked with g++, in order to supply the appropriate C++ libraries. Attempting to link a C++ object file with the C compiler gcc will cause "undefined reference" errors for C++ standard library functions:

$ g++ -Wall -c hello.cc
$ gcc hello.o       (should use g++)
hello.o: In function `main':
hello.o(.text+0x1b): undefined reference to `std::cout'
.....
hello.o(.eh_frame+0x11):
  undefined reference to `__gxx_personality_v0'

Have a look at ImmutableMap JavaDoc: doc

There is information about that there:

Unlike Collections.unmodifiableMap(java.util.Map), which is a view of a separate map which can still change, an instance of ImmutableMap contains its own data and will never change. ImmutableMap is convenient for public static final maps ("constant maps") and also lets you easily make a "defensive copy" of a map provided to your class by a caller.

Creating a singleton decorator (aka an annotation) is an elegant way if you want to decorate (annotate) classes going forward. Then you just put @singleton before your class definition.

def singleton(cls):
    instances = {}
    def getinstance():
        if cls not in instances:
            instances[cls] = cls()
        return instances[cls]
    return getinstance

@singleton
class MyClass:
    ...

Certainly a corner case for this error, but I received it in a different situation, when attempting to overload the assignment operator=. It was a bit cryptic IMO (from g++ 8.1.1).

#include <cstdint>

enum DataType
{
  DT_INT32,
  DT_FLOAT
};

struct PrimitiveData
{
  union MyData
  {
    int32_t i;
    float f;
  } data;

  enum DataType dt;

  template<typename T>
  void operator=(T data)
  {
    switch(dt)
    {
      case DT_INT32:
      {
        data.i = data;
        break;
      }
      case DT_FLOAT:
      {
        data.f = data;
        break;
      }
      default:
      {
        break;
      }
    }
  }
};

int main()
{
  struct PrimitiveData pd;
  pd.dt = DT_FLOAT;
  pd = 3.4f;

  return 0;
}

I received 2 "identical" errors

error: request for member ‘i’ [and 'f'] in ‘data’, which is of non-class type ‘float’

(The equivalent error for clang is: error: member reference base type 'float' is not a structure or union)

for the lines data.i = data; and data.f = data;. Turns out the compiler was confusing local variable name 'data' and my member variable data. When I changed this to void operator=(T newData) and data.i = newData;, data.f = newData;, the error went away.

In my case adding this code to CSS

ul {
    list-style-type: '- ';
}

was enough. Simple as it is.

Simply....If you are not using NDK, there is no problem at all. On the other this is just warning not an error. With warning you can go ahead but not errors. Any it's better to adjust the whitespaces. E.g if your SDK is at C:\program file\Android studio. There is a whitespaces "program file". There are 2 simple methods: 1. Remove the whitespaces 2. Install at another location which don't have whitespaces.

You need to go to user accounts and enable Guest Account, its default disabled. Once you do this, you share any folder and add the guest account to the list of users who can accesss that specific folder, this also includes to Turn off password Protected Sharing in 'Advanced Sharing Settings'

The other way to do this where you only enter a password once is to join a Homegroup. if you have a network of 2 or more computers, they can all connect to a homegroup and access all the files they need from each other, and anyone outside the group needs a 1 time password to be able to access your network, this was introduced in windows 7.

Our company has a 5 second response time standard limit, and we aim for 2-3 seconds in general. This accounts for 98% of page loads. A few particular tasks are allowed to go up to 15 seconds, but we then mitigate that time by putting up a page and refreshing every 5 seconds telling the user that we are still trying to process the request. That way the user sees that something is happening and doesn't just leave. Although, considering that I work on a website whose users are forced to use for business reasons, they aren't going to leave, but they are capable of complaining quite loudly.

In general, if the processing is going to take more than 5 seconds, put up a temporary page so that the user doesn't lose interest.

I have written a complete article at Spring Boot JPA Multiple Data Sources Example. In this article, we will learn how to configure multiple data sources and connect to multiple databases in a typical Spring Boot web application. We will use Spring Boot 2.0.5, JPA, Hibernate 5, Thymeleaf and H2 database to build a simple Spring Boot multiple data sources web application.

There is a racecondition between the last command ($_) and last error ( $?) variables. If you try to store one of them in an own variable, both encountered new values already because of the set command. Actually, last command hasn't got any value at all in this case.

Here is what i did to store (nearly) both informations in own variables, so my bash script can determine if there was any error AND setting the title with the last run command:

   # This construct is needed, because of a racecondition when trying to obtain
   # both of last command and error. With this the information of last error is
   # implied by the corresponding case while command is retrieved.

   if   [[ "${?}" == 0 && "${_}" != "" ]] ; then
    # Last command MUST be retrieved first.
      LASTCOMMAND="${_}" ;
      RETURNSTATUS='?' ;
   elif [[ "${?}" == 0 && "${_}" == "" ]] ; then
      LASTCOMMAND='unknown' ;
      RETURNSTATUS='?' ;
   elif [[ "${?}" != 0 && "${_}" != "" ]] ; then
    # Last command MUST be retrieved first.
      LASTCOMMAND="${_}" ;
      RETURNSTATUS='?' ;
      # Fixme: "$?" not changing state until command executed.
   elif [[ "${?}" != 0 && "${_}" == "" ]] ; then
      LASTCOMMAND='unknown' ;
      RETURNSTATUS='?' ;
      # Fixme: "$?" not changing state until command executed.
   fi

This script will retain the information, if an error occured and will obtain the last run command. Because of the racecondition i can not store the actual value. Besides, most commands actually don't even care for error noumbers, they just return something different from '0'. You'll notice that, if you use the errono extention of bash.

It should be possible with something like a "intern" script for bash, like in bash extention, but i'm not familiar with something like that and it wouldn't be compatible as well.

CORRECTION

I didn't think, that it was possible to retrieve both variables at the same time. Although i like the style of the code, i assumed it would be interpreted as two commands. This was wrong, so my answer devides down to:

   # Because of a racecondition, both MUST be retrieved at the same time.
   declare RETURNSTATUS="${?}" LASTCOMMAND="${_}" ;

   if [[ "${RETURNSTATUS}" == 0 ]] ; then
      declare RETURNSYMBOL='?' ;
   else
      declare RETURNSYMBOL='?' ;
   fi

Although my post might not get any positive rating, i solved my problem myself, finally. And this seems appropriate regarding the intial post. :)

Quite often the issue is a non-breaking space - CHAR(160) - especially from Web text sources -that CLEAN can't remove, so I would go a step further than this and try a formula like this which replaces any non-breaking spaces with a standard one

=TRIM(CLEAN(SUBSTITUTE(A1,CHAR(160)," ")))

Ron de Bruin has an excellent post on tips for cleaning data here

You can also remove the CHAR(160) directly without a workaround formula by

• Edit .... Replace your selected data,
• in Find What hold ALT and type 0160 using the numeric keypad
• Leave Replace With as blank and select Replace All

The method described here is very easy:

Performance-wise, I found the ServiceStack's serializer a bit faster than then others. It's JsonSerializer class in ServiceStack.Text namespace.

https://github.com/ServiceStack/ServiceStack.Text

ServiceStack is available through NuGet package: https://www.nuget.org/packages/ServiceStack/

If you are solely interested in outputting the JSON somewhere in your HTML, you could also use a pipe inside an interpolation. For example:

<p> {{ product | json }} </p>

The best option for me and probably others is the Git reset option:

git reset --hard <commidId> && git clean -f

This has been the best option for me! It is simple, fast and effective!

** Note:** As mentioned in comments don't do this if you're sharing your branch with other people who have copies of the old commits

Also from the comments, if you wanted a less 'ballzy' method you could use

git clean -i

No, you can't undo, rollback or reverse a commit.

STOP THE DATABASE!

(Note: if you deleted the data directory off the filesystem, do NOT stop the database. The following advice applies to an accidental commit of a DELETE or similar, not an rm -rf /data/directory scenario).

If this data was important, STOP YOUR DATABASE NOW and do not restart it. Use pg_ctl stop -m immediate so that no checkpoint is run on shutdown.

You cannot roll back a transaction once it has commited. You will need to restore the data from backups, or use point-in-time recovery, which must have been set up before the accident happened.

If you didn't have any PITR / WAL archiving set up and don't have backups, you're in real trouble.

Urgent mitigation

Once your database is stopped, you should make a file system level copy of the whole data directory - the folder that contains base, pg_clog, etc. Copy all of it to a new location. Do not do anything to the copy in the new location, it is your only hope of recovering your data if you do not have backups. Make another copy on some removable storage if you can, and then unplug that storage from the computer. Remember, you need absolutely every part of the data directory, including pg_xlog etc. No part is unimportant.

Exactly how to make the copy depends on which operating system you're running. Where the data dir is depends on which OS you're running and how you installed PostgreSQL.

Ways some data could've survived

If you stop your DB quickly enough you might have a hope of recovering some data from the tables. That's because PostgreSQL uses multi-version concurrency control (MVCC) to manage concurrent access to its storage. Sometimes it will write new versions of the rows you update to the table, leaving the old ones in place but marked as "deleted". After a while autovaccum comes along and marks the rows as free space, so they can be overwritten by a later INSERT or UPDATE. Thus, the old versions of the UPDATEd rows might still be lying around, present but inaccessible.

Additionally, Pg writes in two phases. First data is written to the write-ahead log (WAL). Only once it's been written to the WAL and hit disk, it's then copied to the "heap" (the main tables), possibly overwriting old data that was there. The WAL content is copied to the main heap by the bgwriter and by periodic checkpoints. By default checkpoints happen every 5 minutes. If you manage to stop the database before a checkpoint has happened and stopped it by hard-killing it, pulling the plug on the machine, or using pg_ctl in immediate mode you might've captured the data from before the checkpoint happened, so your old data is more likely to still be in the heap.

Now that you have made a complete file-system-level copy of the data dir you can start your database back up if you really need to; the data will still be gone, but you've done what you can to give yourself some hope of maybe recovering it. Given the choice I'd probably keep the DB shut down just to be safe.

Recovery

You may now need to hire an expert in PostgreSQL's innards to assist you in a data recovery attempt. Be prepared to pay a professional for their time, possibly quite a bit of time.

I posted about this on the Pg mailing list, and ?????? ?????? linked to depesz's post on pg_dirtyread, which looks like just what you want, though it doesn't recover TOASTed data so it's of limited utility. Give it a try, if you're lucky it might work.

See: pg_dirtyread on GitHub.

I've removed what I'd written in this section as it's obsoleted by that tool.

See also PostgreSQL row storage fundamentals

Prevention

See my blog entry Preventing PostgreSQL database corruption.

On a semi-related side-note, if you were using two phase commit you could ROLLBACK PREPARED for a transction that was prepared for commit but not fully commited. That's about the closest you get to rolling back an already-committed transaction, and does not apply to your situation.

You may find this a little more intuitive. It only requires one function call to array_splice:

$original = array( 'a', 'b', 'c', 'd', 'e' );
$inserted = array( 'x' ); // not necessarily an array, see manual quote

array_splice( $original, 3, 0, $inserted ); // splice in at position 3
// $original is now a b c x d e

If replacement is just one element it is not necessary to put array() around it, unless the element is an array itself, an object or NULL.

Not a direct answer, but a slight variation to use the "functor" template pattern to hide away the specifics of the lambda type and keeps the code nice and simple.

I was not sure how you wanted to use the decide class so I had to extend the class with a function that uses it. See full example here: https://godbolt.org/z/jtByqE

The basic form of your class might look like this:

template <typename Functor>
class Decide
{
public:
    Decide(Functor dec) : _dec{dec} {}
private:
    Functor _dec;
};

Where you pass the type of the function in as part of the class type used like:

auto decide_fc = [](int x){ return x > 3; };
Decide<decltype(decide_fc)> greaterThanThree{decide_fc};

Again, I was not sure why you are capturing x it made more sense (to me) to have a parameter that you pass in to the lambda) so you can use like:

int result = _dec(5); // or whatever value

See the link for a complete example

In case someone is looking for a universal event handler the following code can be used more or less (assuming that name property is set for every input):

    this.handleInputChange = (e) => {
        item[e.target.name] = e.target.type === "checkbox" ? e.target.checked : e.target.value;
    }

It really is an "it depends" kinda question. Some general points:

• NoSQL is typically good for unstructured/"schemaless" data - usually, you don't need to explicitly define your schema up front and can just include new fields without any ceremony
• NoSQL typically favours a denormalised schema due to no support for JOINs per the RDBMS world. So you would usually have a flattened, denormalized representation of your data.
• Using NoSQL doesn't mean you could lose data. Different DBs have different strategies. e.g. MongoDB - you can essentially choose what level to trade off performance vs potential for data loss - best performance = greater scope for data loss.
• It's often very easy to scale out NoSQL solutions. Adding more nodes to replicate data to is one way to a) offer more scalability and b) offer more protection against data loss if one node goes down. But again, depends on the NoSQL DB/configuration. NoSQL does not necessarily mean "data loss" like you infer.
• IMHO, complex/dynamic queries/reporting are best served from an RDBMS. Often the query functionality for a NoSQL DB is limited.
• It doesn't have to be a 1 or the other choice. My experience has been using RDBMS in conjunction with NoSQL for certain use cases.
• NoSQL DBs often lack the ability to perform atomic operations across multiple "tables".

You really need to look at and understand what the various types of NoSQL stores are, and how they go about providing scalability/data security etc. It's difficult to give an across-the-board answer as they really are all different and tackle things differently.

For MongoDb as an example, check out their Use Cases to see what they suggest as being "well suited" and "less well suited" uses of MongoDb.

The question is tagged SQL Server 2000 but for the benefit of people developing on the latest version I'll address that first.

SQL Server 2014

In addition to the methods of adding constraint based indexes discussed below SQL Server 2014 also allows non unique indexes to be specified directly with inline syntax on table variable declarations.

Example syntax for that is below.

/*SQL Server 2014+ compatible inline index syntax*/
DECLARE @T TABLE (
C1 INT INDEX IX1 CLUSTERED, /*Single column indexes can be declared next to the column*/
C2 INT INDEX IX2 NONCLUSTERED,
       INDEX IX3 NONCLUSTERED(C1,C2) /*Example composite index*/
);

Filtered indexes and indexes with included columns can not currently be declared with this syntax however SQL Server 2016 relaxes this a bit further. From CTP 3.1 it is now possible to declare filtered indexes for table variables. By RTM it may be the case that included columns are also allowed but the current position is that they "will likely not make it into SQL16 due to resource constraints"

/*SQL Server 2016 allows filtered indexes*/
DECLARE @T TABLE
(
c1 INT NULL INDEX ix UNIQUE WHERE c1 IS NOT NULL /*Unique ignoring nulls*/
)

SQL Server 2000 - 2012

Can I create a index on Name?

Short answer: Yes.

DECLARE @TEMPTABLE TABLE (
  [ID]   [INT] NOT NULL PRIMARY KEY,
  [Name] [NVARCHAR] (255) COLLATE DATABASE_DEFAULT NULL,
  UNIQUE NONCLUSTERED ([Name], [ID]) 
  ) 

A more detailed answer is below.

Traditional tables in SQL Server can either have a clustered index or are structured as heaps.

Clustered indexes can either be declared as unique to disallow duplicate key values or default to non unique. If not unique then SQL Server silently adds a uniqueifier to any duplicate keys to make them unique.

Non clustered indexes can also be explicitly declared as unique. Otherwise for the non unique case SQL Server adds the row locator (clustered index key or RID for a heap) to all index keys (not just duplicates) this again ensures they are unique.

In SQL Server 2000 - 2012 indexes on table variables can only be created implicitly by creating a UNIQUE or PRIMARY KEY constraint. The difference between these constraint types are that the primary key must be on non nullable column(s). The columns participating in a unique constraint may be nullable. (though SQL Server's implementation of unique constraints in the presence of NULLs is not per that specified in the SQL Standard). Also a table can only have one primary key but multiple unique constraints.

Both of these logical constraints are physically implemented with a unique index. If not explicitly specified otherwise the PRIMARY KEY will become the clustered index and unique constraints non clustered but this behavior can be overridden by specifying CLUSTERED or NONCLUSTERED explicitly with the constraint declaration (Example syntax)

DECLARE @T TABLE
(
A INT NULL UNIQUE CLUSTERED,
B INT NOT NULL PRIMARY KEY NONCLUSTERED
)

As a result of the above the following indexes can be implicitly created on table variables in SQL Server 2000 - 2012.

+-------------------------------------+-------------------------------------+
|             Index Type              | Can be created on a table variable? |
+-------------------------------------+-------------------------------------+
| Unique Clustered Index              | Yes                                 |
| Nonunique Clustered Index           |                                     |
| Unique NCI on a heap                | Yes                                 |
| Non Unique NCI on a heap            |                                     |
| Unique NCI on a clustered index     | Yes                                 |
| Non Unique NCI on a clustered index | Yes                                 |
+-------------------------------------+-------------------------------------+

The last one requires a bit of explanation. In the table variable definition at the beginning of this answer the non unique non clustered index on Name is simulated by a unique index on Name,Id (recall that SQL Server would silently add the clustered index key to the non unique NCI key anyway).

A non unique clustered index can also be achieved by manually adding an IDENTITY column to act as a uniqueifier.

DECLARE @T TABLE
(
A INT NULL,
B INT NULL,
C INT NULL,
Uniqueifier INT NOT NULL IDENTITY(1,1),
UNIQUE CLUSTERED (A,Uniqueifier)
)

But this is not an accurate simulation of how a non unique clustered index would normally actually be implemented in SQL Server as this adds the "Uniqueifier" to all rows. Not just those that require it.

You should find out last timestamp values in each group (subquery), and then join this subquery to the table -

SELECT t1.* FROM messages t1
  JOIN (SELECT from_id, MAX(timestamp) timestamp FROM messages GROUP BY from_id) t2
    ON t1.from_id = t2.from_id AND t1.timestamp = t2.timestamp;

This works for me,

DateTimeFormatInfo usDtfi = new CultureInfo("en-US", false).DateTimeFormat;
DateTimeFormatInfo ukDtfi = new CultureInfo("en-GB", false).DateTimeFormat;
string result = Convert.ToDateTime("26/09/2015",ukDtfi).ToString(usDtfi.ShortDatePattern);

Your code works well you just mistyped this line of code:

document.getElementbyId('lc').appendChild(element);

change it with this: (The "B" should be capitalized.)

document.getElementById('lc').appendChild(element);  

HERE IS MY EXAMPLE:

<html>_x000D_
<head>_x000D_
_x000D_
<script>_x000D_
_x000D_
function test() {_x000D_
_x000D_
    var element = document.createElement("div");_x000D_
    element.appendChild(document.createTextNode('The man who mistook his wife for a hat'));_x000D_
    document.getElementById('lc').appendChild(element);_x000D_
_x000D_
}_x000D_
_x000D_
</script>_x000D_
_x000D_
</head>_x000D_
<body>_x000D_
<input id="filter" type="text" placeholder="Enter your filter text here.." onkeyup = "test()" />_x000D_
_x000D_
<div id="lc" style="background: blue; height: 150px; width: 150px;_x000D_
}" onclick="test();">  _x000D_
</div>_x000D_
</body>_x000D_
_x000D_
</html>

(This is paraphrased from the MS Access help files. I'm sure XL has something similar.) Basically, TimerInterval is a form-level property. Once set, use the sub Form_Timer to carry out your intended action.

Sub Form_Load()
    Me.TimerInterval = 1000 '1000 = 1 second
End Sub

Sub Form_Timer()
    'Do Stuff
End Sub

If the dataframes DO NOT all have the same columns try the following:

df = pd.DataFrame.from_dict(map(dict,df_list))

On CYGwin, you can install this as a typical package in the first screen. Look for

libssl-devel

If you need just a left margin, you can try this:

UItextField *textField = [[UITextField alloc] initWithFrame:...];
UIView *leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, textField.frame.size.height)];
leftView.backgroundColor = textField.backgroundColor;
textField.leftView = leftView;
textField.leftViewMode = UITextFieldViewModeAlways;

It works for me. I hope this may help.

Have that issue. So long time pass... Without side-fields of page it's break normal, but when fields appears, page and "page break space" will scale. So, with a normal field, within a document, it was shown incorrect. I fix it with set

    width:100%

and use

div.page
  {
    page-break-before: always;
    page-break-inside: avoid;
  }

Use it on first line.

There isn't a 1-1 correspondence between IPv4 and IPv6 addresses (nor between IP addresses and devices), so what you're asking for generally isn't possible.

There is a particular range of IPv6 addresses that actually represent the IPv4 address space, but general IPv6 addresses will not be from this range.

Use controller.controller_name

In the Rails Guides, it says:

The params hash will always contain the :controller and :action keys, but you should use the methods controller_name and action_name instead to access these values

ActionController Parameters

So let's say you have a CSS class active , that should be inserted in any link whose page is currently open (maybe so that you can style differently) . If you have a static_pages controller with an about action, you can then highlight the link like so in your view:

<li>
  <a class='button <% if controller.controller_name == "static_pages" && controller.action_name == "about" %>active<%end%>' href="/about">
      About Us
  </a>
</li>

If you are sure there are no leading spaces, you can use bash parameter substitution:

$ string="word1  word2"
$ echo ${string/%\ */}
word1

Watch out for escaping the single space. See here for more examples of substitution patterns. If you have bash > 3.0, you could also use regular expression matching to cope with leading spaces - see here:

$ string="  word1   word2"
$ [[ ${string} =~ \ *([^\ ]*) ]]
$ echo ${BASH_REMATCH[1]}
word1

msg * message goes here

That method is very simple and easy and should work in any batch file i believe. The only "downside" to this method is that it can only show 1 message at once, if there is more than one message it will show each one after the other depending on the order you put them inside the code. Also make sure there is a different looping or continuous operator in your batch file or it will close automatically and only this message will appear. If you need a "quiet" background looping opperator, heres one:

pause >nul

That should keep it running but then it will close after a button is pressed.

Also to keep all the commands "quiet" when running, so they just run and dont display that they were typed into the file, just put the following line at the beginning of the batch file:

@echo off

I hope all these tips helped!

Awesome answers above. I recently had a need to generate simulated data and this is what I landed up using. Sharing in-case helpful to others as well,

import logging
__name__ = "DataSimulator"
logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

import numpy as np
import pandas as pd

def generate_simulated_data(add_anomalies:bool=True, random_state:int=42):
    rnd_state = np.random.RandomState(random_state)
    time = np.linspace(0, 200, num=2000)
    pure = 20*np.sin(time/(2*np.pi))

    # concatenate on the second axis; this will allow us to mix different data 
    # distribution
    data = np.c_[pure]
    mu = np.mean(data)
    sd = np.std(data)
    logger.info(f"Data shape : {data.shape}. mu: {mu} with sd: {sd}")
    data_df = pd.DataFrame(data, columns=['Value'])
    data_df['Index'] = data_df.index.values

    # Adding gaussian jitter
    jitter = 0.3*rnd_state.normal(mu, sd, size=data_df.shape[0])
    data_df['with_jitter'] = data_df['Value'] + jitter

    index_further_away = None
    if add_anomalies:
        # As per the 68-95-99.7 rule(also known as the empirical rule) mu+-2*sd 
        # covers 95.4% of the dataset.
        # Since, anomalies are considered to be rare and typically within the 
        # 5-10% of the data; this filtering
        # technique might work 
        #for us(https://en.wikipedia.org/wiki/68%E2%80%9395%E2%80%9399.7_rule)
        indexes_furhter_away = np.where(np.abs(data_df['with_jitter']) > (mu + 
         2*sd))[0]
        logger.info(f"Number of points further away : 
        {len(indexes_furhter_away)}. Indexes: {indexes_furhter_away}")
        # Generate a point uniformly and embed it into the dataset
        random = rnd_state.uniform(0, 5, 1)
        data_df.loc[indexes_furhter_away, 'with_jitter'] +=  
        random*data_df.loc[indexes_furhter_away, 'with_jitter']
    return data_df, indexes_furhter_away

I had a simular issue and resolved it using android:adjustViewBounds="true" on the ImageView.

<ImageView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:adjustViewBounds="true"
    android:contentDescription="@string/banner_alt"
    android:src="@drawable/banner_portrait" />

Your code is correct, except you are adding (concatenating) strings, not adding integers. Just change your code into:

function compute() {
    if ( $('input[name=type]:checked').val() != undefined ) {
        var a = parseInt($('input[name=service_price]').val());
        var b = parseInt($('input[name=modem_price]').val());
        var total = a+b;
        $('#total_price').val(a+b);
    }
}

and this should work.

Here is some working example that updates the sum when the value when checkbox is checked (and if this is checked, the value is also updated when one of the fields is changed): jsfiddle.

Google wanted to give some more headache to the developers.

So, what you have to do now is edit your AVD and add "Keyboard Support" for it in the Hardware section and change the value to "Yes"

You could always use AlphaMail (disclosure: I'm one of the developers behind it).

Just install with NPM:

npm install alphamail

Sign up for a AlphaMail account. Get a token, and then you can start sending with the AlphaMail service.

var alphamail = require('alphamail');

var emailService = new alphamail.EmailService()
    .setServiceUrl('http://api.amail.io/v1/')
    .setApiToken('YOUR-ACCOUNT-API-TOKEN-HERE');

var person = {
    id: 1234,
    userName: "jdoe75",
    name: {
        first: "John",
        last: "Doe"
    },
    dateOfBirth: 1975
};

emailService.queue(new alphamail.EmailMessagePayload()
    .setProjectId(12345) // ID of your AlphaMail project (determines template, options, etc)
    .setSender(new alphamail.EmailContact("Sender Company Name", "[email protected]"))
    .setReceiver(new alphamail.EmailContact("John Doe", "[email protected]"))
    .setBodyObject(person) // Any serializable object
);

And in the AlphaMail GUI (Dashboard) you'll be able to edit the template with the data you sent:

<html>
    <body>
        <b>Name:</b> <# payload.name.last " " payload.name.first #><br>
        <b>Date of Birth:</b> <# payload.dateOfBirth #><br>

        <# if (payload.id != null) { #>
            <a href="http://company.com/sign-up">Sign Up Free!</a>
        <# } else { #>
            <a href="http://company.com/login?username=<# urlencode(payload.userName) #>">Sign In</a>
        <# } #>
    </body>
</html>

The templates are written in Comlang, it's a simple template language specifically designed for emails.

I agree with Vladimir. The administrators in my company would definitely not appreciate it if I even suggested such a course.

Further, creating an SQL script in stead of blindly trusting Hibernate gives you the opportunity to remove fields which are no longer in use. Hibernate does not do that.

And I find comparing the production schema with the new schema gives you even better insight to wat you changed in the data model. You know, of course, because you made it, but now you see all the changes in one go. Even the ones which make you go like "What the heck?!".

There are tools which can make a schema delta for you, so it isn't even hard work. And then you know exactly what's going to happen.

Update:

ngKeypress, ngKeydown and ngKeyup are now part of AngularJS.

<!-- you can, for example, specify an expression to evaluate -->
<input ng-keypress="count = count + 1" ng-init="count=0">

<!-- or call a controller/directive method and pass $event as parameter.
     With access to $event you can now do stuff like 
     finding which key was pressed -->
<input ng-keypress="changed($event)">

Read more here:

https://docs.angularjs.org/api/ng/directive/ngKeypress https://docs.angularjs.org/api/ng/directive/ngKeydown https://docs.angularjs.org/api/ng/directive/ngKeyup

Earlier solutions:

Solution 1: Use ng-change with ng-model

<input type="text" placeholder="+639178983214" ng-model="mobileNumber" 
ng-controller="RegisterDataController" ng-change="keydown()">

JS:

function RegisterDataController($scope) {       
   $scope.keydown = function() {
        /* validate $scope.mobileNumber here*/
   };
}

Solution 2. Use $watch

<input type="text" placeholder="+639178983214" ng-model="mobileNumber" 
ng-controller="RegisterDataController">
    

JS:

$scope.$watch("mobileNumber", function(newValue, oldValue) {
    /* change noticed */
});

Volatile is also useful, when you want to force the compiler not to optimize a specific code sequence (e.g. for writing a micro-benchmark).

This is not an answer, but it's hard to read if I put results in comment.

I get these results with a Mac Pro (Westmere 6-Cores Xeon 3.33 GHz). I compiled it with clang -O3 -msse4 -lstdc++ a.cpp -o a (-O2 get same result).

clang with uint64_t size=atol(argv[1])<<20;

unsigned    41950110000 0.811198 sec    12.9263 GB/s
uint64_t    41950110000 0.622884 sec    16.8342 GB/s

clang with uint64_t size=1<<20;

unsigned    41950110000 0.623406 sec    16.8201 GB/s
uint64_t    41950110000 0.623685 sec    16.8126 GB/s

I also tried to:

1. Reverse the test order, the result is the same so it rules out the cache factor.
2. Have the for statement in reverse: for (uint64_t i=size/8;i>0;i-=4). This gives the same result and proves the compile is smart enough to not divide size by 8 every iteration (as expected).

Here is my wild guess:

The speed factor comes in three parts:

• code cache: uint64_t version has larger code size, but this does not have an effect on my Xeon CPU. This makes the 64-bit version slower.

• Instructions used. Note not only the loop count, but the buffer is accessed with a 32-bit and 64-bit index on the two versions. Accessing a pointer with a 64-bit offset requests a dedicated 64-bit register and addressing, while you can use immediate for a 32-bit offset. This may make the 32-bit version faster.

• Instructions are only emitted on the 64-bit compile (that is, prefetch). This makes 64-bit faster.

The three factors together match with the observed seemingly conflicting results.

One thing that I have to add is that there is no reference in C.

Secondly, this is the language syntax convention. & - is an address operator but it also mean a reference - all depends on usa case

If there was some "reference" keyword instead of & you could write

int CDummy::isitme (reference CDummy param)

but this is C++ and we should accept it advantages and disadvantages...

I found this FAQ from the US Bureau of Industry and Security very helpful.

Question 15 (What is Note 4?) is the important point:

...

Examples of items that are excluded from Category 5, Part 2 by Note 4 include, but are not limited to, the following:

Consumer applications. Some examples:

You Can not Use the Intent's Context for Creating Intent. So You need to use your Fragment's Parent Activity Context

Intent intent = new Intent(getActivity(),MyClass.class);

    #include<stdio.h>
    #include<string.h>
    int main()
    {
        char s1[50],s2[50];
        printf("Enter the character of strings: ");
        gets(s1);
        printf("\nEnter different character of string to repeat: \n");
        while(strcmp(s1,s2))
        {
            printf("%s\n",s1);
            gets(s2);
        }
        return 0;
    }

This is very simple solution in which you will get your output as you want.

Here is a Python 3, POSIX solution (not Windows!) that uses mmap to map the object into memory.

import hashlib
import mmap

def sha256sum(filename):
    h  = hashlib.sha256()
    with open(filename, 'rb') as f:
        with mmap.mmap(f.fileno(), 0, prot=mmap.PROT_READ) as mm:
            h.update(mm)
    return h.hexdigest()

In visual studio code if your front is too small or too big, then you just need to zoom out or zoom in. To do that you just have to do:

• For zoom in : ctrl + = (ctrl and equal both)
• For zoom out: ctrl + - (ctrl and - both)

Just use "justify-content-center" in the row's class attribute.

<div class="container">
  <div class="row justify-content-center">
    <h1>This is a header</h1>
  </div>
</div>

i myself like setTimeout more that setInterval but didn't find a solution in class based component .you could use sth like this in class based components:

class based component and setInterval:

class Clock extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      date: new Date()
    };
  }

  componentDidMount() {
    this.timerID = setInterval(
      () => this.tick(),
      1000
    );
  }

  componentWillUnmount() {
    clearInterval(this.timerID);
  }

  tick() {
    this.setState({
      date: new Date()
    });
  }

  render() {
    return (
      this.state.date.toLocaleTimeString()
    );
  }
}

ReactDOM.render( 
  <Clock / > ,
  document.getElementById('app')
);

You could start by reading the documentation for Date. Then you realize that Date’s methods are all deprecated and turn to Calender instead.

Calendar now = Calendar.getInstance();
System.out.println(now.get(Calendar.DAY_OF_MONTH));

On my side, this error came from the data type "INT' in the Null values column. The error is resolved by just changing the data a type to varchar.

Well I did not think this was possible until I went and checked. In some previous version of Excel I could not do this. I am currently using Excel 2013.

This is what you want to do in a scatter plot:

1. right click on your data point

2. select "Format Data Labels" (note you may have to add data labels first)

3. put a check mark in "Values from Cells"
4. click on "select range" and select your range of labels you want on the points

UPDATE: Colouring Individual Labels

In order to colour the labels individually use the following steps:

1. select a label. When you first select, all labels for the series should get a box around them like the graph above.
2. Select the individual label you are interested in editing. Only the label you have selected should have a box around it like the graph below.
3. On the right hand side, as shown below, Select "TEXT OPTIONS".
4. Expand the "TEXT FILL" category if required.
5. Second from the bottom of the category list is "COLOR", select the colour you want from the pallet.

If you have the entire series selected instead of the individual label, text formatting changes should apply to all labels instead of just one.

Here is a version of the answer in

Swift 5

// MARK: - Hiding Back Button

extension UINavigationItem {

    /// A Boolean value that determines whether the back button is hidden.
    ///
    /// When set to `true`, the back button is hidden when this navigation item
    /// is the top item. This is true regardless of the value in the
    /// `leftItemsSupplementBackButton` property. When set to `false`, the back button
    /// is shown if it is still present. (It can be replaced by values in either
    /// the `leftBarButtonItem` or `leftBarButtonItems` properties.) The default value is `false`.
    @IBInspectable var hideBackButton: Bool {
        get { hidesBackButton }
        set { hidesBackButton = newValue }
    }
}

Every navigation item of a view controller will have this new property in the top section of attributes inspector

exit(0); // at the end of main function before closing curly braces

Edit:

Well, he edited his post.

If an Object inherits Iterable, you are given the ability to use the for-each loop as such:

for(Object object : objectListVar) {
     //code here
}

So in your case, if you wanted to update your Guns and their Bullets:

for(Gun g : guns) {
     //invoke any methods of each gun
     ArrayList<Bullet> bullets = g.getBullets()
     for(Bullet b : bullets) {
          System.out.println("X: " + b.getX() + ", Y: " + b.getY());
          //update, check for collisions, etc
     }
}

First get your third Gun object:

Gun g = gunList.get(2);

Then iterate over the third gun's bullets:

ArrayList<Bullet> bullets = g.getBullets();

for(Bullet b : bullets) {
     //necessary code here
}

If the column is not a PK you could always create a NEW column in the table with the incremented numbers, drop the original and then alter the new one to be the old.

curious as to why you might need to do this... most I've ever had to futz with Identity columns was to backfill numbers and I just ended up using DBCC CHECKIDENT ( tablename,RESEED,newnextnumber)

good luck!

If it is VIM for Windows, you can do the following:

• enter your message following the presented guidelines
• press Esc to make sure you are out of the insert mode
• then type :wqEnter or ZZ.

Note that in VIM there are often several ways to do one thing. Here there is a slight difference though. :wqEnter always writes the current file before closing it, while ZZ, :xEnter, :xiEnter, :xitEnter, :exiEnter and :exitEnter only write it if the document is modified.
All these synonyms just have different numbers of keypresses.

You need to declare disconnectFunc as a function pointer, not a void pointer. You also need to call it as a function (with parentheses), and no "*" is needed.

I've opened a similar question in the Doctrine user mailing list and got a really simple answer;

consider the many to many relation as an entity itself, and then you realize you have 3 objects, linked between them with a one-to-many and many-to-one relation.

http://groups.google.com/group/doctrine-user/browse_thread/thread/d1d87c96052e76f7/436b896e83c10868#436b896e83c10868

Once a relation has data, it's no more a relation !

Adding this to your code android:focusableInTouchMode="true" will make sure that your keypad doesn't appear on startup for your edittext box. You want to add this line to your linear layout that contains the EditTextBox. You should be able to play with this to solve both your problems. I have tested this. Simple solution.

ie: In your app_list_view.xml file

<LinearLayout 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" 
    android:focusableInTouchMode="true">
    <EditText 
        android:id="@+id/filter_edittext"       
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:hint="Search" 
        android:inputType="text" 
        android:maxLines="1"/>
    <ListView 
        android:id="@id/android:list" 
        android:layout_height="fill_parent"
        android:layout_weight="1.0" 
        android:layout_width="fill_parent" 
        android:focusable="true" 
        android:descendantFocusability="beforeDescendants"/>
</LinearLayout> 

------------------ EDIT: To Make keyboard appear on startup -----------------------

This is to make they Keyboard appear on the username edittextbox on startup. All I've done is added an empty Scrollview to the bottom of the .xml file, this puts the first edittext into focus and pops up the keyboard. I admit this is a hack, but I am assuming you just want this to work. I've tested it, and it works fine.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:paddingLeft="20dip"  
    android:paddingRight="20dip">
    <EditText 
        android:id="@+id/userName" 
        android:singleLine="true" 
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content" 
        android:hint="Username"  
        android:imeOptions="actionDone" 
        android:inputType="text"
        android:maxLines="1"
       />
    <EditText 
        android:id="@+id/password" 
        android:password="true" 
        android:singleLine="true"  
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:hint="Password" />
    <ScrollView
        android:id="@+id/ScrollView01"  
        android:layout_height="fill_parent"   
        android:layout_width="fill_parent"> 
    </ScrollView>
</LinearLayout>

If you are looking for a more eloquent solution, I've found this question which might help you out, it is not as simple as the solution above but probably a better solution. I haven't tested it but it apparently works. I think it is similar to the solution you've tried which didn't work for you though.

Hope this is what you are looking for.

Cheers!

Consider if your file is read only, then the extra parameters may help with FileStream

using (var fs = new FileStream(path, FileMode.Open, FileAccess.Read))

In my particular case I needed to ensure the array remained intact so this worked for me:

// Empty array
arr1.length = 0;
// Add items from source array to target array
for (var i = 0; i < arr2.length; i++) {
    arr1.push(arr2[i]);
}

What about BASE58 encoding the URL? Like for example flickr does.

# note the missing lowercase L and the zero etc.
BASE58 = '123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ' 
url = ''
while node_id >= 58:
    div, mod = divmod(node_id, 58)
    url = BASE58[mod] + url
    node_id = int(div)

return 'http://short.com/%s' % BASE58[node_id] + url

Turning that back into a number isn't a big deal either.

With the latter example you omit the struct keyword when using the structure. So everywhere in your code, you can write :

myStruct a;

instead of

struct myStruct a;

This save some typing, and might be more readable, but this is a matter of taste

$(window).on("touchstart", function(ev) {
    var e = ev.originalEvent;
    console.log(e.touches);
});

I know it been asked a long time ago, but I thought a concrete example might help.

I already have answered here and it's working for me, please refer this link https://stackoverflow.com/a/40133225/3636561

    String socailLink="https://www.facebook.com/kfc";
    Intent intent = new Intent(Intent.ACTION_VIEW);
    String facebookUrl = Utils.getFacebookUrl(getActivity(), socailLink);
    if (facebookUrl == null || facebookUrl.length() == 0) {
        Log.d("facebook Url", " is coming as " + facebookUrl);
        return;
    }
    intent.setData(Uri.parse(facebookUrl));
    startActivity(intent);

please refer link to get rest part.

If you want to check for false and alert if not, then no there isn't.

If you use if(val), then anything that evaluates to 'truthy', like a non-empty string, will also pass. So it depends on how stringent your criterion is. Using === and !== is generally considered good practice, to avoid accidentally matching truthy or falsy conditions via JavaScript's implicit boolean tests.

Indirect via Your Server - Calling 3rd Party API - secure and recommended

Your server can call the 3rd Party API after proper authentication and authorization. The API Keys are not exposed to client.

node.js - https://www.npmjs.org/package/node-mandrill

const mandrill = require('node-mandrill')('<your API Key>'); 

function sendEmail ( _name, _email, _subject, _message) {
    mandrill('/messages/send', {
        message: {
            to: [{email: _email , name: _name}],
            from_email: '[email protected]',
            subject: _subject,
            text: _message
        }
    }, function(error, response){
        if (error) console.log( error );
        else console.log(response);
    });
}

// define your own email api which points to your server.

app.post( '/api/sendemail/', function(req, res){
            
    let _name = req.body.name;
    let _email = req.body.email;
    let _subject = req.body.subject;
    let _messsage = req.body.message;

    //implement your spam protection or checks. 

    sendEmail ( _name, _email, _subject, _message );

});

and then use use $.ajax on client to call your email API.

Directly From Client - Calling 3rd Party API - not recomended

Send an email using only JavaScript

in short:

1. register for Mandrill to get an API key
2. load jQuery
3. use $.ajax to send an email

Like this -

function sendMail() {
    $.ajax({
      type: 'POST',
      url: 'https://mandrillapp.com/api/1.0/messages/send.json',
      data: {
        'key': 'YOUR API KEY HERE',
        'message': {
          'from_email': '[email protected]',
          'to': [
              {
                'email': '[email protected]',
                'name': 'RECIPIENT NAME (OPTIONAL)',
                'type': 'to'
              }
            ],
          'autotext': 'true',
          'subject': 'YOUR SUBJECT HERE!',
          'html': 'YOUR EMAIL CONTENT HERE! YOU CAN USE HTML!'
        }
      }
     }).done(function(response) {
       console.log(response); // if you're into that sorta thing
     });
}

Note: Keep in mind that your API key is visible to anyone, so any malicious user may use your key to send out emails that can eat up your quota.

The issue is shadow coming out the side of the containing div. In order to avoid this, the blur value must equal the absolute value of the spread value.

div {_x000D_
  -webkit-box-shadow: 0 4px 6px -6px #222;_x000D_
  -moz-box-shadow: 0 4px 6px -6px #222;_x000D_
  box-shadow: 0 4px 6px -6px #222;_x000D_
}

<div>wefwefwef</div>

Not to repeat, but one point to those who might still be confused after reading many answers:

• pass by value in Java is NOT EQUAL to pass by value in C++, though it sounds like that, which is probably why there's confusion

Breaking it down:

• pass by value in C++ means passing the value of the object (if object), literarily the copy of the object
• pass by value in Java means passing the address value of the object (if object), not really the "value" (a copy) of the object like C++
• By pass by value in Java, operating on an object (e.g. myObj.setName("new")) inside a function has effects on the object outside the function; by pass by value in C++, it has NO effects on the one outside.
• However, by pass by reference in C++, operating on an object in a function DOES have effects on the one outside! Similar (just similar, not the same) to pass by value in Java, no?.. and people always repeat "there's no pass by reference in Java", => BOOM, confusion starts...

So, friends, all is just about the difference of terminology definition (across languages), you just need to know how it works and that's it (though sometimes a bit confusing how it's called I admit)!

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

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

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

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

Hope this helps.. :-)

Use toString() when you want to present information to a user (including a developer looking at a log). Never rely in your code on toString() giving a specific value. Never test it against a specific string. If your code breaks when someone correctly changes the toString() return, then it was already broken.

If you need to get the exact name used to declare the enum constant, you should use name() as toString may have been overridden.

In Python 3.5.1 things like these work:

c = input('Enter number:')
print (int(float(c)))
print (round(float(c)))

and

Enter number:  4.7
4
5

A simpler way to wait is to use System.currentTimeMillis(), which returns the number of milliseconds since midnight on January 1, 1970 UTC. For example, to wait 5 seconds:

public static void main(String[] args) {
    //some code
    long original = System.currentTimeMillis();
    while (true) {
        if (System.currentTimeMillis - original >= 5000) {
            break;
        }
    }
    //more code after waiting
}

This way, you don't have to muck about with threads and exceptions. Hope this helps!

This is a rather late answer, but you can use

body {
   transform: scale(1.1);
   transform-origin: 0 0;
   // add prefixed versions too.
}

to zoom the page by 110%. Although the zoom style is there, Firefox still does not support it sadly.

Also, this is slightly different than your zoom. The css transform works like an image zoom, so it will enlarge your page but not cause reflow, etc.

Edit updated the transform origin.

You want rows where that condition is true so you need a comma:

data[data$Ozone > 14, ]

javascript's parseFloat doesn't take a locale parameter. So you will have to replace , with .

parseFloat('0,04'.replace(/,/, '.')); // 0.04

COUNTER=1
while [ Your != "done" ]
do
     echo " $COUNTER "
     COUNTER=$[$COUNTER +1]
done

No.

The content-type should be whatever it is known to be, if you know it. application/octet-stream is defined as "arbitrary binary data" in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything "webby". Or to look at it from another direction; the only thing one can safely do with application/octet-stream is to save it to file and hope someone else knows what it's for.

You can combine the use of Content-Disposition with other content-types, such as image/png or even text/html to indicate you want saving rather than display. It used to be the case that some browsers would ignore it in the case of text/html but I think this was some long time ago at this point (and I'm going to bed soon so I'm not going to start testing a whole bunch of browsers right now; maybe later).

RFC 2616 also mentions the possibility of extension tokens, and these days most browsers recognise inline to mean you do want the entity displayed if possible (that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter). This is of course the default behaviour anyway, but it means that you can include the filename part of the header, which browsers will use (perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not) as the suggestion if the user tries to save.

Hence:

Content-Type: application/octet-stream
Content-Disposition: attachment; filename="picture.png"

Means "I don't know what the hell this is. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: attachment; filename="picture.png"

Means "This is a PNG image. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: inline; filename="picture.png"

Means "This is a PNG image. Please display it unless you don't know how to display PNG images. Otherwise, or if the user chooses to save it, we recommend the name picture.png for the file you save it as".

Of those browsers that recognise inline some would always use it, while others would use it if the user had selected "save link as" but not if they'd selected "save" while viewing (or at least IE used to be like that, it may have changed some years ago).

Unless you need mod_rewrite for other things, using Apache core IF directive is cleaner & faster:

<If "%{HTTPS} == 'off'">
Redirect permanent / https://yoursite.com/
</If>

You can add more conditions to the IF directive, such as ensure a single canonical domain without the www prefix:

<If "req('Host') != 'myonetruesite.com' || %{HTTPS} == 'off'">
Redirect permanent / https://myonetruesite.com/
</If>

There's a lot of familiarity inertia in using mod_rewrite for everything, but see if this works for you.

More info: https://httpd.apache.org/docs/2.4/mod/core.html#if

To see it in action (try without www. or https://, or with .net instead of .com): https://nohodental.com/ (a site I'm working on).

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

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

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

It was throwing me this error when I using switch in a function with variables declared in my class:

private void ShowCalendar(final Activity context, Point p, int type) 
{
    switch (type) {
        case type_cat:
            break;

        case type_region:
            break;

        case type_city:
            break;

        default:
            //sth
            break;
    }
}

The problem was solved when I declared final to the variables in the start of the class:

final int type_cat=1, type_region=2, type_city=3;

I have this issue, and all I did was make sure that I was referencing the right .Net framework in all the projects then just change the web.config from

From

<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/>

To

<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework" requirePermission="false"/>

All works..

Give the div you don't want him inheriting the property background too.

If you are using Docker make sure you are not using the same port in another service, in my case i was mistakenly using the same port for both PostgreSQL and Redis.

Use setBackgroundColor(Color.TRANSPARENT) to set the background as transparent, or use setBackgroundColor(0). Here Color.TRANSPARENT is the default attribute from color class. It will work fine.

In openCV's documentation there is an example for getting video frame by frame. It is written in c++ but it is very easy to port the example to python - you can search for each fumction documentation to see how to call them in python.

#include "opencv2/opencv.hpp"

using namespace cv;

int main(int, char**)
{
    VideoCapture cap(0); // open the default camera
    if(!cap.isOpened())  // check if we succeeded
        return -1;

    Mat edges;
    namedWindow("edges",1);
    for(;;)
    {
        Mat frame;
        cap >> frame; // get a new frame from camera
        cvtColor(frame, edges, CV_BGR2GRAY);
        GaussianBlur(edges, edges, Size(7,7), 1.5, 1.5);
        Canny(edges, edges, 0, 30, 3);
        imshow("edges", edges);
        if(waitKey(30) >= 0) break;
    }
    // the camera will be deinitialized automatically in VideoCapture destructor
    return 0;
}

Edit. Found a neater way!

One argument that the button can receive is (id)sender. This means you can create a new button, inheriting from UIButton, that allows you to store the other intended arguments. Hopefully these two snippets illustrate what to do.

  myOwnbutton.argOne = someValue
  [myOwnbutton addTarget:self action:@selector(buttonTouchUpInside:) forControlEvents:UIControlEventTouchUpInside];

and

- (IBAction) buttonTouchUpInside:(id)sender {
  MyOwnButton *buttonClicked = (MyOwnButton *)sender; 
  //do as you please with buttonClicked.argOne
}

This was my original suggestion.

There is a way to achieve the same result, but it's not pretty. Suppose you want to add a parameter to your navigate method. The code below will not allow you to pass that parameter to navigate.

[button addTarget:self action:@selector(navigate) forControlEvents:UIControlEventTouchUpInside];

To get around this you can move the navigate method to a class of it's own and set the "parameters" as attributes of that class...

NavigationAid *navAid = [[NavigationAid alloc] init];
navAid.firstParam = someVariableOne
navAid.secondParam = someVariableTwo
[button addTarget:navAid action:@selector(navigate) forControlEvents:UIControlEventTouchUpInside];

Of course you can keep the navigate method in the original class and have it called by navAid, as long as it knows where to find it.

NavigationAid *navAid = [[NavigationAid alloc] init];
navAid.whereToCallNavigate = self
navAid.firstParam = someVariableOne
navAid.secondParam = someVariableTwo
[button addTarget:navAid action:@selector(navigate) forControlEvents:UIControlEventTouchUpInside];

Like I said, it's not pretty, but it worked for me and I haven't found anyone suggesting any other working solution.

The mail function do not guarantee the actual delivery of mail. All it do is to pass the message to external program (usually sendmail). You need a properly configured SMTP server in order for this to work. Also keep in mind it does not support SMTP authentication. You may check out the PEAR::Mail library of SwiftMailer, both of them give you more options.

I'll leave the discussion of the difference between Build Tools, Platform Tools, and Tools to others. From a practical standpoint, you only need to know the answer to your second question:

Which version should be used?

Answer: Use the most recent version.

For those using Android Studio with Gradle, the buildToolsVersion has to be set in the build.gradle (Module: app) file.

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"

    ...
}

Where do I get the most recent version number of Build Tools?

Open the Android SDK Manager.

• In Android Studio go to Tools > Android > SDK Manager > Appearance & Behavior > System Settings > Android SDK
• Choose the SDK Tools tab.
• Select Android SDK Build Tools from the list
• Check Show Package Details.

The last item will show the most recent version.

Make sure it is installed and then write that number as the buildToolsVersion in build.gradle (Module: app).

Please have a look at http://jsfiddle.net/2dJAN/59/

$("#submit").click(function () {
var url = $(location).attr('href');
$('#spn_url').html('<strong>' + url + '</strong>');
});

I was having this issue and none of these answers were able to help me with the issue. For anyone else who happens to have the same problem, here is a possible solution that worked for me. Simply reformat the code to be the following:

$("#postcontent").submit(function(e) {
  $.ajax({
    type:"POST",
    url:"add_new_post.php",
    data:$("#postcontent").serialize(),
    beforeSend:function(){
      $(".post_submitting").show().html("<center><img src='images/loading.gif'/></center>");
    },
    success (response) {   
      //alert(response);
      $("#return_update_msg").html(response); 
      $(".post_submitting").fadeOut(1000);                
    },
    error (data) {
      // handle the error
    }
  });
});

The difference in the code is that this code has an error handler. You can choose to handle the error however you wish but it is best practice to have the error handler in case of an exception. Also, the formatting of the success and error functions within the ajax function are different. This is the only format for success/error that would work for me. Hope it helps!

}
</script>

The ValueTuple types are built into newer frameworks:

• .NET Framework 4.7
• .NET Core 2.0
• Mono 5.0
• .Net Standard 2.0

Until you target one of those newer framework versions, you need to reference the ValueTuple package.

I'm passing to Django's template a function, which returns me some records

Why don't you pass to Django template the variable storing function's return value, instead of the function?

I've tried to set fuction's return value to a variable and iterate over variable, but there seems to be no way to set variable in Django template.

You should set variables in Django views instead of templates, and then pass them to the template.

Just Try to do like this....

SortedDictionary<string, int> userCache = UserCache.getSortedUserValueCache();

    // Add this code
    if(userCache != null)
    {
        userListComboBox.DataSource = new BindingSource(userCache, null); // Key => null
        userListComboBox.DisplayMember = "Key";
        userListComboBox.ValueMember = "Value";
    }

HTML:

function fun(obj) {
    var uid= $(obj).attr('data-uid');
    var name= $(obj).attr('data-name');
    var value= $(obj).attr('data-value');
}

but I'm using jQuery.

Whenever you try to show a Link on a page thats outside the BrowserRouter you will get that error.

This error message is essentially saying that any component that is not a child of our <Router> cannot contain any React Router related components.

You need to migrate your component hierarchy to how you see it in the first answer above. For anyone else reviewing this post who may need to look at more examples.

Let's say you have a Header.jscomponent that looks like this:

import React from 'react';
import { Link } from 'react-router-dom';

const Header = () => {
    return (
        <div className="ui secondary pointing menu">
            <Link to="/" className="item">
                Streamy
            </Link>
            <div className="right menu">
                <Link to="/" className="item">
                    All Streams
                </Link>
            </div>
        </div>
    );
};

export default Header;

And your App.js file looks like this:

import React from 'react';
import { BrowserRouter, Route, Link } from 'react-router-dom';
import StreamCreate from './streams/StreamCreate';
import StreamEdit from './streams/StreamEdit';
import StreamDelete from './streams/StreamDelete';
import StreamList from './streams/StreamList';
import StreamShow from './streams/StreamShow';
import Header from './Header';

const App = () => {
  return (
    <div className="ui container">
      <Header />
      <BrowserRouter>
        <div>
        <Route path="/" exact component={StreamList} />
        <Route path="/streams/new" exact component={StreamCreate} />
        <Route path="/streams/edit" exact component={StreamEdit} />
        <Route path="/streams/delete" exact component={StreamDelete} />
        <Route path="/streams/show" exact component={StreamShow} />
        </div> 
      </BrowserRouter>
    </div>
  );
};

export default App;

Notice that the Header.js component is making use of the Link tag from react-router-dom but the componet was placed outside the <BrowserRouter>, this will lead to the same error as the one experience by the OP. In this case, you can make the correction in one move:

import React from 'react';
import { BrowserRouter, Route } from 'react-router-dom';
import StreamCreate from './streams/StreamCreate';
import StreamEdit from './streams/StreamEdit';
import StreamDelete from './streams/StreamDelete';
import StreamList from './streams/StreamList';
import StreamShow from './streams/StreamShow';
import Header from './Header';

const App = () => {
  return (
    <div className="ui container">
      <BrowserRouter>
        <div>
        <Header />
        <Route path="/" exact component={StreamList} />
        <Route path="/streams/new" exact component={StreamCreate} />
        <Route path="/streams/edit" exact component={StreamEdit} />
        <Route path="/streams/delete" exact component={StreamDelete} />
        <Route path="/streams/show" exact component={StreamShow} />
        </div> 
      </BrowserRouter>
    </div>
  );
};

export default App;

Please review carefully and ensure you have the <Header /> or whatever your component may be inside of not only the <BrowserRouter> but also inside of the <div>, otherwise you will also get the error that a Router may only have one child which is referring to the <div> which is the child of <BrowserRouter>. Everything else such as Route and components must go within it in the hierarchy.

So now the <Header /> is a child of the <BrowserRouter> within the <div> tags and it can successfully make use of the Link element.

I was having trouble with DBCP when the connections times out so I trialled c3p0. I was going to release this to production but then started performance testing. I found that c3p0 performed terribly. I couldn't configure it to perform well at all. I found it twice as slow as DBCP.

I then tried the Tomcat connection pooling.

This was twice as fast as c3p0 and fixed other issues I was having with DBCP. I spent a lot of time investigating and testing the 3 pools. My advice if you are deploying to Tomcat is to use the new Tomcat JDBC pool.

you can use pass inside if statement.

you can read empList directly in forEach tag.Try this

 <table>
       <c:forEach items="${sessionScope.empList}" var="employee">
            <tr>
                <td>Employee ID: <c:out value="${employee.eid}"/></td>
                <td>Employee Pass: <c:out value="${employee.ename}"/></td>  
            </tr>
        </c:forEach>
    </table>
