XML Blueprint also does that; instructions here
http://www.xmlblueprint.com/help/html/topic_170.htm
It's not free, but there's a 10-day free trial; it seems fast and efficient; unfortunately it's Windows only.
In my case I have solved this annoying warning by simply adding the <!DOCTYPE xml>
after the <?xml ... >
tag.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
PCDATA
is text that will be parsed by a parser. Tags inside the text
will be treated as markup and entities will be expanded. CDATA
is text that will not be parsed by a parser. Tags inside the text will
not be treated as markup and entities will not be expanded.By default, everything is PCDATA
. In the following example, ignoring the root, <bar>
will be parsed, and it'll have no content, but one child.
<?xml version="1.0"?>
<foo>
<bar><test>content!</test></bar>
</foo>
When we want to specify that an element will only contain text, and no child elements, we use the keyword PCDATA
, because this keyword specifies that the element must contain parsable character data – that is , any text except the characters less-than (<
) , greater-than (>
) , ampersand (&
), quote('
) and double quote ("
).
In the next example, <bar>
contains CDATA
. Its content will not be parsed and is thus <test>content!</test>
.
<?xml version="1.0"?>
<foo>
<bar><![CDATA[<test>content!</test>]]></bar>
</foo>
There are several content models in SGML. The #PCDATA
content model says that an element may contain plain text. The "parsed" part of it means that markup (including PIs, comments and SGML directives) in it is parsed instead of displayed as raw text. It also means that entity references are replaced.
Another type of content model allowing plain text contents is CDATA
. In XML, the element content model may not implicitly be set to CDATA
, but in SGML, it means that markup and entity references are ignored in the contents of the element. In attributes of CDATA
type however, entity references are replaced.
In XML, #PCDATA
is the only plain text content model. You use it if you at all want to allow text contents in the element. The CDATA
content model may be used explicitly through the CDATA
block markup in #PCDATA
, but element contents may not be defined as CDATA
per default.
In a DTD, the type of an attribute that contains text must be CDATA
. The CDATA
keyword in an attribute declaration has a different meaning than the CDATA
section in an XML document. In a CDATA
section all characters are legal (including <
,>
,&
,'
and "
characters), except the ]]>
end tag.
#PCDATA
is not appropriate for the type of an attribute. It is used for the type of "leaf" text.
#PCDATA
is prepended by a hash in the content model to distinguish this keyword from an element named PCDATA
(which would be perfectly legal).
From the Differences Between DTDs and Schema section of the Converting a DTD into a Schema article:
The critical difference between DTDs and XML Schema is that XML Schema utilize an XML-based syntax, whereas DTDs have a unique syntax held over from SGML DTDs. Although DTDs are often criticized because of this need to learn a new syntax, the syntax itself is quite terse. The opposite is true for XML Schema, which are verbose, but also make use of tags and XML so that authors of XML should find the syntax of XML Schema less intimidating.
The goal of DTDs was to retain a level of compatibility with SGML for applications that might want to convert SGML DTDs into XML DTDs. However, in keeping with one of the goals of XML, "terseness in XML markup is of minimal importance," there is no real concern with keeping the syntax brief.
[...]
So what are some of the other differences which might be especially important when we are converting a DTD? Let's take a look.
Typing
The most significant difference between DTDs and XML Schema is the capability to create and use datatypes in Schema in conjunction with element and attribute declarations. In fact, it's such an important difference that one half of the XML Schema Recommendation is devoted to datatyping and XML Schema. We cover datatypes in detail in Part III of this book, "XML Schema Datatypes."
[...]
Occurrence Constraints
Another area where DTDs and Schema differ significantly is with occurrence constraints. If you recall from our previous examples in Chapter 2, "Schema Structure" (or your own work with DTDs), there are three symbols that you can use to limit the number of occurrences of an element: *, + and ?.
[...]
Enumerations
So, let's say we had a element, and we wanted to be able to define a size attribute for the shirt, which allowed users to choose a size: small, medium, or large. Our DTD would look like this:
<!ELEMENT item (shirt)> <!ELEMENT shirt (#PCDATA)> <!ATTLIST shirt size_value (small | medium | large)>
[...]
But what if we wanted
size
to be an element? We can't do that with a DTD. DTDs do not provide for enumerations in an element's text content. However, because of datatypes with Schema, when we declared the enumeration in the preceding example, we actually created asimpleType
calledsize_values
which we can now use with an element:<xs:element name="size" type="size_value">
[...]
Try this in your code:
import Foo from './Foo';
import Bar from './Bar';
// without default
export {
Foo,
Bar,
}
Btw, you can also do it this way:
// bundle.js
export { default as Foo } from './Foo'
export { default as Bar } from './Bar'
export { default } from './Baz'
// and import somewhere..
import Baz, { Foo, Bar } from './bundle'
Using export
export const MyFunction = () => {}
export const MyFunction2 = () => {}
const Var = 1;
const Var2 = 2;
export {
Var,
Var2,
}
// Then import it this way
import {
MyFunction,
MyFunction2,
Var,
Var2,
} from './foo-bar-baz';
The difference with export default
is that you can export something, and apply the name where you import it:
// export default
export default class UserClass {
constructor() {}
};
// import it
import User from './user'
you can try to export as "Runnable jar" in eclipse. I have also problems, when i export as "jar", but i have never problems when i export as "Runnable jar".

someone here may find it useful. hhb_curl_exec2 works pretty much like curl_exec, but arg3 is an array which will be populated with the returned http headers (numeric index), and arg4 is an array which will be populated with the returned cookies ($cookies["expires"]=>"Fri, 06-May-2016 05:58:51 GMT"), and arg5 will be populated with... info about the raw request made by curl.
the downside is that it requires CURLOPT_RETURNTRANSFER to be on, else it error out, and that it will overwrite CURLOPT_STDERR and CURLOPT_VERBOSE, if you were already using them for something else.. (i might fix this later)
example of how to use it:
<?php

Wrap your OutputStream with a PrintWriter and use the print methods on that class. They take in a String and do the work for you.
Finally found a solution from : Detect different device platforms using CSS
<link rel="stylesheet" media="all and (device-width: 768px) and (device-height: 1024px) and (orientation:portrait)" href="ipad-portrait.css" />
<link rel="stylesheet" media="all and (device-width: 768px) and (device-height: 1024px) and (orientation:landscape)" href="ipad-landscape.css" />
To reduce HTTP call, this can also be used inside you existing common CSS file:
@media all and (device-width: 768px) and (device-height: 1024px) and (orientation:portrait) {
.ipad-portrait { color: red; } /* your css rules for ipad portrait */
}
@media all and (device-width: 1024px) and (device-height: 768px) and (orientation:landscape) {
.ipad-landscape { color: blue; } /* your css rules for ipad landscape */
}
Hope this helps.

Can't you create a subclass of Dictionary which has that functionality?

{
get
{
return base[key];

EDIT: Sorry, didn't get code right first time.
You could use sum
function to achieve that as @EdChum mentioned in the comment:
df['C'] = df[['A', 'B']].sum(axis=1)
In [245]: df
Out[245]:
A B C
0 1 4 5
1 2 6 8
2 3 9 12
To list tags I prefer:
git tag -n
The -n
flag displays the first line of the annotation message along with the tag, or the first commit message line if the tag is not annotated.
You can also do git tag -n5
to show the first 5 lines of the annotation.
Or count all lines in subdirectories with a file name pattern (e.g. logfiles with timestamps in the file name):
wc -l ./**/*_SuccessLog.csv
If the value stored in PropertyLoader.RET_SECONDARY_V_ARRAY
is not "V_ARRAY"
, then you are using different types; even if they are declared identically (e.g. both are table of number
) this will not work.
You're hitting this data type compatibility restriction:
You can assign a collection to a collection variable only if they have the same data type. Having the same element type is not enough.
You're trying to call the procedure with a parameter that is a different type to the one it's expecting, which is what the error message is telling you.
First, the ++ operator takes precedence over the * operator, and the () operators take precedence over everything else.
Second, the ++number operator is the same as the number++ operator if you're not assigning them to anything. The difference is number++ returns number and then increments number, and ++number increments first and then returns it.
Third, by increasing the value of a pointer, you're incrementing it by the sizeof its contents, that is you're incrementing it as if you were iterating in an array.
So, to sum it all up:
ptr++; // Pointer moves to the next int position (as if it was an array)
++ptr; // Pointer moves to the next int position (as if it was an array)
++*ptr; // The value of ptr is incremented
++(*ptr); // The value of ptr is incremented
++*(ptr); // The value of ptr is incremented
*ptr++; // Pointer moves to the next int position (as if it was an array). But returns the old content
(*ptr)++; // The value of ptr is incremented
*(ptr)++; // Pointer moves to the next int position (as if it was an array). But returns the old content
*++ptr; // Pointer moves to the next int position, and then get's accessed, with your code, segfault
*(++ptr); // Pointer moves to the next int position, and then get's accessed, with your code, segfault
As there are a lot of cases in here, I might have made some mistake, please correct me if I'm wrong.
EDIT:
So I was wrong, the precedence is a little more complicated than what I wrote, view it here: http://en.cppreference.com/w/cpp/language/operator_precedence
change type="number" to type="tel"
Are you using retrolambda? If so, just do JAVA_HOME=$JAVA8_HOME

Try this.
public function insert_data_function($your_data)
{
$this->db->insert("your_table",$your_data);
$last_id = $this->db->insert_id();
return $last_id;
}
Nowadays your compiler should do all the work for you. At least of what I know gcc is very efficient in optimizing calls to memset
away (better check the assembler, though).
Then also, avoid memset
if you don't have to:
... = { 0
}
) for stack memoryAnd for really large chunks use mmap
if you have it. This just gets zero initialized memory from the system "for free".
I modified the code from correct answer to get result in seconds:
long startTime = System.nanoTime();
methodCode ...
long endTime = System.nanoTime();
double duration = (double)(endTime - startTime) / (Math.pow(10, 9));
Log.v(TAG, "MethodName time (s) = " + duration);
Why not use Model.update? After all you're not using the found user for anything else than to update it's properties:
User.update({username: oldUsername}, {
username: newUser.username,
password: newUser.password,
rights: newUser.rights
}, function(err, numberAffected, rawResponse) {
//handle it
})
You need to pass the whole point to location
var point = new Point(50, 100);
this.balancePanel.Location = point;
Use the .clone() method on your List. It will return a shallow copy, meaning that it will contain pointers to the same objects, so you won't have to copy the list. Then just use Collections.
Ergo,
Collections.reverse(list.clone());
If you are using a List
and don't have access to clone()
you can use subList()
:
List<?> shallowCopy = list.subList(0, list.size());
Collections.reverse(shallowCopy);
Use org.apache.commons.io.IOUtils
InputStream inStream = new ...
OutputStream outStream = new ...
IOUtils.copy(inStream, outStream);
or copyLarge for size >2GB
Just came across this one, as I need to print all models with their attributes(built on @Aditya Sanghi's comment):
ActiveRecord::Base.connection.tables.map{|x|x.classify.safe_constantize}.compact.each{ |model| print "\n\n"+model.name; model.new.attributes.each{|a,b| print "\n#{a}"}}
Another way of stopping logs completely is:
import org.apache.log4j.Appender;
import org.apache.log4j.BasicConfigurator;
import org.apache.log4j.varia.NullAppender;
public class SomeClass {
public static void main(String[] args) {
Appender nullAppender = new NullAppender();
BasicConfigurator.configure(nullAppender);
{...more code here...}
}
}
This worked for me. An NullAppender is
An Appender that ignores log events. (https://logging.apache.org/log4j/2.x/log4j-core/apidocs/org/apache/logging/log4j/core/appender/NullAppender.html)
This worked for me as-
HTML-
<div style="background-color: #535; width: 100%; height: 80px;">
<div class="center">
Test <br>
kumar adnioas<br>
sanjay<br>
1990
</div>
</div>
CSS-
.center {
position: relative;
left: 50%;
top: 50%;
height: 82%;
transform: translate(-50%, -50%);
transform: -webkit-translate(-50%, -50%);
transform: -ms-translate(-50%, -50%);
}
Hope will help you too.
Including the fb:app_id
tag in your HTML HEAD will allow the Facebook scraper to associate the Open Graph entity for that URL with an application. This will allow any admins of that app to view Insights about that URL and any social plugins connected with it.
The fb:admins
tag is similar, but allows you to just specify each user ID that you would like to give the permission to do the above.
You can include either of these tags or both, depending on how many people you want to admin the Insights, etc. A single as fb:admins
is pretty much a minimum requirement. The rest of the Open Graph tags will still be picked up when people share and like your URL, however it may cause problems in the future, so please include one of the above.
fb:admins is specified like this:
<meta property="fb:admins" content="USER_ID"/>
OR
<meta property="fb:admins" content="USER_ID,USER_ID2,USER_ID3"/>
and fb:app_id like this:
<meta property="fb:app_id" content="APPID"/>
That should work. I am not sure why it's failing. You're quoting your variables properly. What happens if you use this script with double [[
]]
?
if [[ -d $PASSED ]]; then
echo "$PASSED is a directory"
elif [[ -f $PASSED ]]; then
echo "$PASSED is a file"
else
echo "$PASSED is not valid"
exit 1
fi
Double square brackets is a bash extension to [ ]
. It doesn't require variables to be quoted, not even if they contain spaces.
Also worth trying: -e
to test if a path exists without testing what type of file it is.
echo "Enter no of terms"
read count
for i in $(seq 1 $count)
do
t=` expr $i - 1 `
for j in $(seq $t -1 0)
do

j=` expr $count + 1 `
x=` expr $j - $i `
for k in $(seq 1 $x)
do
echo -n "* "
done
echo ""

Microsoft SQL (AFAIK) does not allow you to alter the table and add a column after a specific column. Your best bet is using Sql Server Management Studio, or play around with either dropping and re-adding the table, or creating a new table and moving the data over manually. neither are very graceful.
MySQL does however:
ALTER TABLE mytable
ADD COLUMN new_column <type>
AFTER existing_column
Include <%@ page isELIgnored="false"%>
on top of your jsp page.
{% if profile.user.first_name %}
works (assuming you also don't want to accept ''
).
if
in Python in general treats None
, False
, ''
, []
, {}
, ... all as false.
So ... more digging, with the result. It seems that although I ran one process normal and one "As Administrator", I had UAC off. Turning UAC to medium allowed me to see different results. Basically, it all boils down to integrity levels, which are 5.
Browsers, for example, run at Low Level (1), while services (System user) run at System Level (4). Everything is very well explained in Windows Integrity Mechanism Design . When UAC is enabled, processes are created with Medium level (SID S-1-16-8192 AKA 0x2000 is added) while when "Run as Administrator", the process is created with High Level (SID S-1-16-12288 aka 0x3000).
So the correct ACCESS_TOKEN for a normal user (Medium Integrity level) is:
0:000:x86> !token

Simplest way of doing it:

git remote add origin https://github.com/abc/repo.git
git push origin master
Once the push to GitHub is successful, delete the old remote by running:
git remote rm repo_bitbucket
here's what I did to alert user in case their network went down or upon page update failure:
I have a div-tag on the page where I put current time and update this tag every 10 seconds. It looks something like this: <div id="reloadthis">22:09:10</div>
At the end of the javascript function that updates the time in the div-tag, I put this (after time is updated with AJAX):
var new_value = document.getElementById('reloadthis').innerHTML;
var new_length = new_value.length;
if(new_length<1){
alert("NETWORK ERROR!");
}
That's it! You can replace the alert-part with anything you want, of course. Hope this helps.
Here is a solution using Streams with Java 8
// lets assume the original list is filled with {1,1,2,3,6,3,8,7}
List<String> original = new ArrayList<>();
List<String> result = new ArrayList<>();
You just look if the frequency of this object is more than once in your list. Then call .distinct() to only have unique elements in your result
result = original.stream()
.filter(e -> Collections.frequency(original, e) > 1)
.distinct()
.collect(Collectors.toList());
// returns {1,3}
// returns only numbers which occur more than once
result = original.stream()
.filter(e -> Collections.frequency(original, e) == 1)
.collect(Collectors.toList());
// returns {2,6,8,7}
// returns numbers which occur only once
result = original.stream()
.distinct()
.collect(Collectors.toList());
// returns {1,2,3,6,8,7}
// returns the list without duplicates
this works for me

In R, whether a number is numeric or integer can be determined by class function. Generally all numbers are stored as numeric and to explicitly define a number as integer we need to specify 'L' after the number.
Example:
x <- 1
class(x)
[1] "numeric"
x <- 1L
class(x)
[1] "integer"
I hope this is what was needed. Thanks :)
It registers the driver; something of the form:
public class SomeDriver implements Driver {
static {
try {
DriverManager.registerDriver(new SomeDriver());
} catch (SQLException e) {
// TODO Auto-generated catch block
}
}
//etc: implemented methods
}
I have experience this issue in past. Based on that I can say that generally we get this issue if your dataset has multiple fieldnames that points to same field source. Take a look into following posts for detail error description
http://www.bi-rootdata.com/2012/09/an-error-occurred-during-report.html
http://www.bi-rootdata.com/2012/09/an-item-with-same-key-has-already-been.html
In your case, you should check your all field names returned by Sp prc_RPT_Select_BI_Completes_Data_View and make sure that all fields has unique name.
Quick note: if you're also using coord_flip()
to flip the x and the y axis, you won't be able to set range limits using coord_cartesian()
because those two functions are exclusive (see here).
Fortunately, this is an easy fix; set your limits within coord_flip()
like so:
p + coord_flip(ylim = c(3,5), xlim = c(100, 400))
This just alters the visible range (i.e. doesn't remove data points).
All major browsers now include native JSON encoding/decoding.
// To encode an object (This produces a string)
var json_str = JSON.stringify(myobject);
// To decode (This produces an object)
var obj = JSON.parse(json_str);
Note that only valid JSON data will be encoded. For example:
var obj = {'foo': 1, 'bar': (function (x) { return x; })}
JSON.stringify(obj) // --> "{\"foo\":1}"
Valid JSON types are: objects, strings, numbers, arrays, true
, false
, and null
.
Some JSON resources:
This one works like a charm!

1) Also you can use lateinit
If you sure do your initialization later on onCreate()
or elsewhere.
Use this
lateinit var left: Node
Instead of this
var left: Node? = null
2) And there is other way that use !!
end of variable when you use it like this
queue.add(left!!) // add !!
$curl_handle=curl_init();
curl_setopt($curl_handle, CURLOPT_URL,'https://www.xxxSite/get_quote/ajaxGetQuoteJSON.jsp?symbol=IRCTC&series=EQ');
//Set the GET method by giving 0 value and for POST set as 1
//curl_setopt($curl_handle, CURLOPT_POST, 0);
curl_setopt($curl_handle, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
$query = curl_exec($curl_handle);
$data = json_decode($query, true);
curl_close($curl_handle);
//print complete object, just echo the variable not work so you need to use print_r to show the result
echo print_r( $data);
//at first layer
echo $data["tradedDate"];
//Inside the second layer
echo $data["data"][0]["companyName"];
Some time you might get 405, set the method type correctly.
how about simply:

os.system('dir c:\\')
Another option is to utilize lambda casting in non-ambiguous contexts into one class:
public static class Lambdas {
public static <T> Predicate<T> as(Predicate<T> predicate){
return predicate;
}
public static <T> Consumer<T> as(Consumer<T> consumer){
return consumer;
}
public static <T> Supplier<T> as(Supplier<T> supplier){
return supplier;
}
public static <T, R> Function<T, R> as(Function<T, R> function){
return function;
}
}
... and then static import the utility class:
stream.filter(as(String::isEmpty).negate())
Actually looking at other areas, if you open with _blank it keeps the sessionStorage as long as you're opening the tab when the parent is open:
In this link, there's a good jsfiddle to test it. sessionStorage on new window isn't empty, when following a link with target="_blank"
For Python 3 below eliminates overhead of list conversion:
first = next(iter(prices.values()))
Seaborn's barplot returns an axis-object (not a figure). This means you can do the following:
import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
fake = pd.DataFrame({'cat': ['red', 'green', 'blue'], 'val': [1, 2, 3]})
ax = sns.barplot(x = 'val', y = 'cat',
data = fake,
color = 'black')
ax.set(xlabel='common xlabel', ylabel='common ylabel')
plt.show()

If you want to notify your JTable
about changes of your data, use
tableModel.fireTableDataChanged()
From the documentation:
Notifies all listeners that all cell values in the table's rows may have changed. The number of rows may also have changed and the JTable should redraw the table from scratch. The structure of the table (as in the order of the columns) is assumed to be the same.
Let the method return a object from a common baseclass or interface.

It looks like the machine you're trying to run this on has only 256 MB memory.
Maybe the JVM tries to allocate a large, contiguous block of 64 MB memory. The 192 MB that you have free might be fragmented into smaller pieces, so that there is no contiguous block of 64 MB free to allocate.
Try starting your Java program with a smaller heap size, for example:
java -Xms16m ...
As a developer of SpeedView: GPS speedometer for Android, I must have tried every possible solution to this problem, all with the same negative result. Let's reiterate what doesn't work:
So here's the only working solution I found, and the one that I actually use in my app. Let's say we have this simple class that implements the GpsStatus.Listener:
private class MyGPSListener implements GpsStatus.Listener {
public void onGpsStatusChanged(int event) {
switch (event) {
case GpsStatus.GPS_EVENT_SATELLITE_STATUS:
if (mLastLocation != null)
isGPSFix = (SystemClock.elapsedRealtime() - mLastLocationMillis) < 3000;
if (isGPSFix) { // A fix has been acquired.
// Do something.
} else { // The fix has been lost.
// Do something.
}
break;
case GpsStatus.GPS_EVENT_FIRST_FIX:
// Do something.
isGPSFix = true;
break;
}
}
}
OK, now in onLocationChanged() we add the following:
@Override
public void onLocationChanged(Location location) {
if (location == null) return;
mLastLocationMillis = SystemClock.elapsedRealtime();
// Do something.
mLastLocation = location;
}
And that's it. Basically, this is the line that does it all:
isGPSFix = (SystemClock.elapsedRealtime() - mLastLocationMillis) < 3000;
You can tweak the millis value of course, but I'd suggest to set it around 3-5 seconds.
This actually works and although I haven't looked at the source code that draws the native GPS icon, this comes close to replicating its behaviour. Hope this helps someone.
Start from pandas 0.13, this is the most efficient way.
df.query('Gender=="Male" & Year=="2014" ')
You can use the sort
command:
sort -k2 -n yourfile
-n
,--numeric-sort
compare according to string numerical value
For example:
$ cat ages.txt
Bob 12
Jane 48
Mark 3
Tashi 54
$ sort -k2 -n ages.txt
Mark 3
Bob 12
Jane 48
Tashi 54
Adding skipLibCheck: true
in compilerOptions
inside tsconfig.json
file fixed my issue.
"compilerOptions": {

},
And if you need to style your form elements according to it's state (modified/not modified) dynamically or to test whether some values has actually changed, you can use the following module, developed by myself: https://github.com/betsol/angular-input-modified
It adds additional properties and methods to the form and it's child elements. With it, you can test whether some element contains new data or even test if entire form has new unsaved data.
You can setup the following watch: $scope.$watch('myForm.modified', handler)
and your handler will be called if some form elements actually contains new data or if it reversed to initial state.
Also, you can use modified
property of individual form elements to actually reduce amount of data sent to a server via AJAX call. There is no need to send unchanged data.
As a bonus, you can revert your form to initial state via call to form's reset()
method.
You can find the module's demo here: http://plnkr.co/edit/g2MDXv81OOBuGo6ORvdt?p=preview
Cheers!

man printf.1
has a note at the bottom: "...your shell may have its own version of printf
...". This question is tagged for bash
, but if at all possible, I try to write scripts portable to any shell. dash
is usually a good minimum baseline for portability - so the answer here works in bash
, dash
, & zsh
. If a script works in those 3, it's most likely portable to just about anywhere.
The latest implementation of printf
in dash
[1] doesn't colorize output given a %s
format specifier with an ANSI escape character \e
-- but, a format specifier %b
combined with octal \033
(equivalent to an ASCII ESC
) will get the job done. Please comment for any outliers, but AFAIK, all shells have implemented printf
to use the ASCII octal subset at a bare minimum.
To the title of the question "Using colors with printf", the most portable way to set formatting is to combine the %b
format specifier for printf
(as referenced in an earlier answer from @Vlad) with an octal escape \033
.
portable-color.sh
#/bin/sh
P="\033["
BLUE=34
printf "-> This is %s %-6s %s text \n" $P"1;"$BLUE"m" "blue" $P"0m"
printf "-> This is %b %-6s %b text \n" $P"1;"$BLUE"m" "blue" $P"0m"
Outputs:
$ ./portable-color.sh
-> This is \033[1;34m blue \033[0m text
-> This is blue text
...and 'blue' is blue in the second line.
The %-6s
format specifier from the OP is in the middle of the format string between the opening & closing control character sequences.

Bit late to this party but I came up with, what I think, is a unique solution. Rather than trying to insert your own ellipsis through css trickery or js I thought i'd try and roll with the single line only restriction. So I duplicate the text for every "line" and just use a negative text-indent to make sure one line starts where the last one stops. FIDDLE
CSS:
#wrapper{
font-size: 20pt;
line-height: 22pt;
width: 100%;
overflow: hidden;
padding: 0;
margin: 0;
}
.text-block-line{
height: 22pt;
display: inline-block;
max-width: 100%;
overflow: hidden;
white-space: nowrap;
width: auto;
}
.text-block-line:last-child{
text-overflow: ellipsis;
}
/*the follwing is suboptimal but neccesary I think. I'd probably just make a sass mixin that I can feed a max number of lines to and have them avialable. Number of lines will need to be controlled by server or client template which is no worse than doing a character count clip server side now. */
.line2{
text-indent: -100%;
}
.line3{
text-indent: -200%;
}
.line4{
text-indent: -300%;
}
HTML:
<p id="wrapper" class="redraw">
<span class="text-block-line line1">This text is repeated for every line that you want to be displayed in your element. This example has a max of 4 lines before the ellipsis occurs. Try scaling the preview window width to see the effect.</span>

More details in the fiddle. There is an issue with the browser reflowing that I use a JS redraw for and such so do check it out but this is the basic concept. Any thoughts/suggestions are much appreciated.
This is a common question in C++ programming. There are two valid answers to this. There are advantages and disadvantages to both answers and your choice will depend on context. The common answer is to put all the implementation in the header file, but there's another approach will will be suitable in some cases. The choice is yours.
The code in a template is merely a 'pattern' known to the compiler. The compiler won't compile the constructors cola<float>::cola(...)
and cola<string>::cola(...)
until it is forced to do so. And we must ensure that this compilation happens for the constructors at least once in the entire compilation process, or we will get the 'undefined reference' error. (This applies to the other methods of cola<T>
also.)
The problem is caused by the fact that main.cpp
and cola.cpp
will be compiled separately first. In main.cpp
, the compiler will implicitly instantiate the template classes cola<float>
and cola<string>
because those particular instantiations are used in main.cpp
. The bad news is that the implementations of those member functions are not in main.cpp
, nor in any header file included in main.cpp
, and therefore the compiler can't include complete versions of those functions in main.o
. When compiling cola.cpp
, the compiler won't compile those instantiations either, because there are no implicit or explicit instantiations of cola<float>
or cola<string>
. Remember, when compiling cola.cpp
, the compiler has no clue which instantiations will be needed; and we can't expect it to compile for every type in order to ensure this problem never happens! (cola<int>
, cola<char>
, cola<ostream>
, cola< cola<int> >
... and so on ...)
The two answers are:
cola.cpp
, which particular template classes will be required, forcing it to compile cola<float>
and cola<string>
.main.cpp
) uses the template class.At the end of cola.cpp
, you should add lines explicitly instantiating all the relevant templates, such as
template class cola<float>;
template class cola<string>;
and you add the following two lines at the end of nodo_colaypila.cpp
:
template class nodo_colaypila<float>;
template class nodo_colaypila<std :: string>;
This will ensure that, when the compiler is compiling cola.cpp
that it will explicitly compile all the code for the cola<float>
and cola<string>
classes. Similarly, nodo_colaypila.cpp
contains the implementations of the nodo_colaypila<...>
classes.
In this approach, you should ensure that all the of the implementation is placed into one .cpp
file (i.e. one translation unit) and that the explicit instantation is placed after the definition of all the functions (i.e. at the end of the file).
The common answer is to move all the code from the implementation files cola.cpp
and nodo_colaypila.cpp
into cola.h
and nodo_colaypila.h
. In the long run, this is more flexible as it means you can use extra instantiations (e.g. cola<char>
) without any more work. But it could mean the same functions are compiled many times, once in each translation unit. This is not a big problem, as the linker will correctly ignore the duplicate implementations. But it might slow down the compilation a little.
The default answer, used by the STL for example and in most of the code that any of us will write, is to put all the implementations in the header files. But in a more private project, you will have more knowledge and control of which particular template classes will be instantiated. In fact, this 'bug' might be seen as a feature, as it stops users of your code from accidentally using instantiations you have not tested for or planned for ("I know this works for cola<float>
and cola<string>
, if you want to use something else, tell me first and will can verify it works before enabling it.").
Finally, there are three other minor typos in the code in your question:
#endif
at the end of nodo_colaypila.hnodo_colaypila<T>* ult, pri;
should be nodo_colaypila<T> *ult, *pri;
- both are pointers.nodo_colaypila.h
, not in this implementation file.TLDR; (just read the bold text)
Most answers here will tell you how to create an empty DataFrame and fill it out, but no one will tell you that it is a bad thing to do.
Here is my advice: Accumulate data in a list, not a DataFrame.
Use a list to collect your data, then initialise a DataFrame when you are ready. Either a list-of-lists or list-of-dicts format will work, pd.DataFrame
accepts both.
data = []
for a, b, c in some_function_that_yields_data():
data.append([a, b, c])
df = pd.DataFrame(data, columns=['A', 'B', 'C'])
Pros of this approach:
It is always cheaper to append to a list and create a DataFrame in one go than it is to create an empty DataFrame (or one of NaNs) and append to it over and over again.
Lists also take up less memory and are a much lighter data structure to work with, append, and remove (if needed).
dtypes
are automatically inferred (rather than assigning object
to all of them).
A RangeIndex
is automatically created for your data, instead of you having to take care to assign the correct index to the row you are appending at each iteration.
If you aren't convinced yet, this is also mentioned in the documentation:
Iteratively appending rows to a DataFrame can be more computationally intensive than a single concatenate. A better solution is to append those rows to a list and then concatenate the list with the original DataFrame all at once.
That's fine, you can still do this in linear time by growing or creating a python list of smaller DataFrames, then calling pd.concat
.
small_dfs = []
for small_df in some_function_that_yields_dataframes():
small_dfs.append(small_df)
large_df = pd.concat(small_dfs, ignore_index=True)
or, more concisely:
large_df = pd.concat(
list(some_function_that_yields_dataframes()), ignore_index=True)
append
or concat
inside a loopHere is the biggest mistake I've seen from beginners:
df = pd.DataFrame(columns=['A', 'B', 'C'])
for a, b, c in some_function_that_yields_data():
df = df.append({'A': i, 'B': b, 'C': c}, ignore_index=True) # yuck
# or similarly,
# df = pd.concat([df, pd.Series({'A': i, 'B': b, 'C': c})], ignore_index=True)
Memory is re-allocated for every append
or concat
operation you have. Couple this with a loop and you have a quadratic complexity operation.
The other mistake associated with df.append
is that users tend to forget append is not an in-place function, so the result must be assigned back. You also have to worry about the dtypes:
df = pd.DataFrame(columns=['A', 'B', 'C'])
df = df.append({'A': 1, 'B': 12.3, 'C': 'xyz'}, ignore_index=True)
df.dtypes
A object # yuck!
B float64
C object
dtype: object
Dealing with object columns is never a good thing, because pandas cannot vectorize operations on those columns. You will need to do this to fix it:
df.infer_objects().dtypes
A int64
B float64
C object
dtype: object
loc
inside a loopI have also seen loc
used to append to a DataFrame that was created empty:
df = pd.DataFrame(columns=['A', 'B', 'C'])
for a, b, c in some_function_that_yields_data():
df.loc[len(df)] = [a, b, c]
As before, you have not pre-allocated the amount of memory you need each time, so the memory is re-grown each time you create a new row. It's just as bad as append
, and even more ugly.
And then, there's creating a DataFrame of NaNs, and all the caveats associated therewith.
df = pd.DataFrame(columns=['A', 'B', 'C'], index=range(5))
df
A B C
0 NaN NaN NaN
1 NaN NaN NaN
2 NaN NaN NaN
3 NaN NaN NaN
4 NaN NaN NaN
It creates a DataFrame of object columns, like the others.
df.dtypes
A object # you DON'T want this
B object
C object
dtype: object
Appending still has all the issues as the methods above.
for i, (a, b, c) in enumerate(some_function_that_yields_data()):
df.iloc[i] = [a, b, c]
Timing these methods is the fastest way to see just how much they differ in terms of their memory and utility.
I had the same issue when using the alpine
image.
My .sh
file had the following first line:
#!/bin/bash
Alpine does not have bash. So changing the line to
#!/bin/sh
or installing bash with
apk add --no-cache bash
solved the issue for me.
Generic:
ALTER TABLE table_name
DROP COLUMN column1,column2,column3;
E.g:
ALTER TABLE Student
DROP COLUMN Name, Number, City;
EDIT:
Indeed there was a patch which included sign()
in math, but it wasn't accepted, because they didn't agree on what it should return in all the edge cases (+/-0, +/-nan, etc)
So they decided to implement only copysign, which (although more verbose) can be used to delegate to the end user the desired behavior for edge cases - which sometimes might require the call to cmp(x,0)
.
I don't know why it's not a built-in, but I have some thoughts.
copysign(x,y):
Return x with the sign of y.
Most importantly, copysign
is a superset of sign
! Calling copysign
with x=1 is the same as a sign
function. So you could just use copysign
and forget about it.
>>> math.copysign(1, -4)
-1.0
>>> math.copysign(1, 3)
1.0
If you get sick of passing two whole arguments, you can implement sign
this way, and it will still be compatible with the IEEE stuff mentioned by others:
>>> sign = functools.partial(math.copysign, 1) # either of these
>>> sign = lambda x: math.copysign(1, x) # two will work
>>> sign(-4)
-1.0
>>> sign(3)
1.0
>>> sign(0)
1.0
>>> sign(-0.0)
-1.0
>>> sign(float('nan'))
-1.0
Secondly, usually when you want the sign of something, you just end up multiplying it with another value. And of course that's basically what copysign
does.
So, instead of:
s = sign(a)
b = b * s
You can just do:
b = copysign(b, a)
And yes, I'm surprised you've been using Python for 7 years and think cmp
could be so easily removed and replaced by sign
! Have you never implemented a class with a __cmp__
method? Have you never called cmp
and specified a custom comparator function?
In summary, I've found myself wanting a sign
function too, but copysign
with the first argument being 1 will work just fine. I disagree that sign
would be more useful than copysign
, as I've shown that it's merely a subset of the same functionality.
Intercept the KeyPressed event is in my opinion a good solid solution. Pay attention to trigger code characters (e.KeyChar lower then 32) if you use a RegExp.
But in this way is still possible to inject characters out of range whenever the user paste text from the clipboard. Unfortunately I did not found correct clipboard events to fix this.
So a waterproof solution is to intercept TextBox.TextChanged. Here is sometimes the original out of range character visible, for a short time. I recommend to implement both.

I had the same problem with a similar string like yours
{id:1,field1:"someField"},{id:2,field1:"someOtherField"}
The problem here is the structure of the string. The json parser wasn't recognizing that it needs to create 2 objects in this case. So what I did is kind of silly, I just re-structured my string and added the []
with this the parser recognized
var myString = {id:1,field1:"someField"},{id:2,field1:"someOtherField"}
myString = '[' + myString +']'
var json = $.parseJSON(myString)
Hope it helps,
If anyone has a more elegant approach please share.
I had this issue when I was using TouchID if that helps anyone else, wrap your success logic which likely does something with the UI in the main queue.
In a GET request, you pass parameters as part of the query string.
string url = "http://somesite.com?var=12345";
HashMap does not allow primitive data types as arguments. It can only accept objects so
HashMap<int, myObject> myMap = new HashMap<int, myObject>();
will not work.
You have to change the declaration to
HashMap<Integer, myObject> myMap = new HashMap<Integer, myObject>();
so even when you do the following
myMap.put(2,myObject);
The primitive data type is autoboxed to an Integer object.
8 (int) === boxing ===> 8 (Integer)
You can read more on autoboxing here http://docs.oracle.com/javase/tutorial/java/data/autoboxing.html
You need to do something like this:
// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");
// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");
// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
// grab the "id" attribute
XmlAttribute idAttribute = aNode.Attributes["id"];
// check if that attribute even exists...
if (idAttribute != null)
{
// if yes - read its current value
string currentValue = idAttribute.Value;
// here, you can now decide what to do - for demo purposes,
// I just set the ID value to a fixed value if it was empty before
if (string.IsNullOrEmpty(currentValue))
{
idAttribute.Value = "515";
}
}
}
// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");
I got this error when calling this code: wks.Range[startCell, endCell]
where the startCell
Range and endCell
Range were pointing to different worksheet then the variable wks
.
I hit this error and it turned out my connection string was pointing to another database, obviously the table didn't exist there.
I spent a few hours on this and no one else has mentioned to double check your connection string.
I'm not sure when this was written, but currently to add or remove a default from a column in a migration, you can use the following:
change_column_null :products, :name, false
Rails 5:
change_column_default :products, :approved, from: true, to: false
http://edgeguides.rubyonrails.org/active_record_migrations.html#changing-columns
Rails 4.2:
change_column_default :products, :approved, false
http://guides.rubyonrails.org/v4.2/active_record_migrations.html#changing-columns
Which is a neat way of avoiding looking through your migrations or schema for the column specifications.
('.cat').hover(
function () {
$(this).show();
},
function () {
$(this).hide();
}
);
It's the same for the others.
For the smooth fade in you can use fadeIn
and fadeOut
Based on Daren's excellent answer, note that this code can be shortened significantly by using the appropriate XslCompiledTransform.Transform overload:
var myXslTrans = new XslCompiledTransform();
myXslTrans.Load("stylesheet.xsl");
myXslTrans.Transform("source.xml", "result.html");
(Sorry for posing this as an answer, but the code block
support in comments is rather limited.)
In VB.NET, you don't even need a variable:
With New XslCompiledTransform()
.Load("stylesheet.xsl")
.Transform("source.xml", "result.html")
End With
Use FileSaver.js
. It supports Chrome, Edge, Firefox, and IE 10+ (and probably IE < 10 with a few "polyfills" - see Note 4). FileSaver.js
implements the saveAs() FileSaver interface in browsers that do not natively support it:
https://github.com/eligrey/FileSaver.js
Minified version is really small at < 2.5KB, gzipped < 1.2KB.
Usage:
/* TODO: replace the blob content with your byte[] */
var blob = new Blob([yourBinaryDataAsAnArrayOrAsAString], {type: "application/octet-stream"});
var fileName = "myFileName.myExtension";
saveAs(blob, fileName);
You might need Blob.js in some browsers (see Note 3). Blob.js implements the W3C Blob interface in browsers that do not natively support it. It is a cross-browser implementation:
https://github.com/eligrey/Blob.js
Consider StreamSaver.js if you have files larger than blob's size limitations.

Using ScrollView
is not very difficult. You can just add one to your layout and put whatever you want to scroll inside. ScrollView
only takes one child so if you want to put a few things inside then you should make the first thing be something like a LinearLayout
.
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!-- things to scroll -->
</LinearLayout>
</ScrollView>
If you want to scroll things horizontally, then use a HorizontalScrollView
.
As is talked about in this post, sometimes you want the ScrollView
content to fill the screen. For example, if you had some buttons at the end of a readme. You want the buttons to always be at the end of the text and at bottom of the screen, even if the text doesn't scroll.
If the content scrolls, everything is fine. However, if the content is smaller than the size of the screen, the buttons are not at the bottom.
This can be solved with a combination of using fillViewPort
on the ScrollView
and using a layout weight on the content. Using fillViewPort
makes the ScrollView
fill the parent area. Setting the layout_weight
on one of the views in the LinearLayout
makes that view expand to fill any extra space.
Here is the XML
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"> <--- fillViewport
<LinearLayout

android:layout_height="wrap_content"

android:layout_weight="1" <--- set layout_weight
android:layout_width="match_parent"
android:padding="6dp"
android:text="hello"/>
<LinearLayout
android:layout_height="wrap_content" <--- wrap_content
android:layout_width="match_parent"
android:background="@android:drawable/bottom_bar"
android:gravity="center_vertical">
<Button
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Accept" />
<Button
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Refuse" />
</LinearLayout>
</LinearLayout>

The idea for this answer came from a previous answer that is now deleted (link for 10K users). The content of this answer is an update and adaptation of this post.
In the browser, use document.querySelect('[attribute-name]')
.
But if you're unit testing and your mocked dom has a flakey querySelector implementation, this will do the trick.
This is @kevinfahy's answer, just trimmed down to be a bit with ES6 fat arrow functions and by converting the HtmlCollection into an array at the cost of readability perhaps.
So it'll only work with an ES6 transpiler. Also, I'm not sure how performant it'll be with a lot of elements.
function getElementsWithAttribute(attribute) {
return [].slice.call(document.getElementsByTagName('*'))
.filter(elem => elem.getAttribute(attribute) !== null);
}
And here's a variant that will get an attribute with a specific value
function getElementsWithAttributeValue(attribute, value) {
return [].slice.call(document.getElementsByTagName('*'))
.filter(elem => elem.getAttribute(attribute) === value);
}
I would simply do the following to backup all new files from 7 days ago
tar --newer $(date -d'7 days ago' +"%d-%b") -zcf thisweek.tgz .
note you can also replace '7 days ago' with anything that suits your need
Can be : date -d'yesterday' +"%d-%b"
Or even : date -d'first Sunday last month' +"%d-%b"
Very basic but
$.load()
: Load a piece of html into a container DOM.$.get()
: Use this if you want to make a GET call and play extensively with the response.$.post()
: Use this if you want to make a POST call and don’t want to load the response to some container DOM.$.ajax()
: Use this if you need to do something when XHR fails, or you need to specify ajax options (e.g. cache: true) on the fly.In your layout you can add android:checked="true"
to CheckBox
you want to be selected.
Or programmatically, you can use the setChecked method defined in the checkable interface:
RadioButton b = (RadioButton) findViewById(R.id.option1);
b.setChecked(true);
In the case where you simply want to delete a project from the head revision, so that it no longer shows up in your repo when you run svn list file:///path/to/repo/
just run:
svn delete file:///path/to/repo/project
However, if you need to delete all record of it in the repo, use another method.

Another related tip is to use "%~1" instead of "%1". Type "CALL /?" at the command line in Windows to get more details.
For multilined elements, why not something like
$ array=($(echo -e $'a a\nb b' | tr ' ' '§')) && array=("${array[@]//§/ }") && echo "${array[@]/%/ INTERELEMENT}"
a a INTERELEMENT b b INTERELEMENT
When you define your function using this syntax:
def someFunc(*args):
for x in args
print x
You're telling it that you expect a variable number of arguments. If you want to pass in a List (Array from other languages) you'd do something like this:
def someFunc(myList = [], *args):
for x in myList:
print x
Then you can call it with this:
items = [1,2,3,4,5]
someFunc(items)
You need to define named arguments before variable arguments, and variable arguments before keyword arguments. You can also have this:
def someFunc(arg1, arg2, arg3, *args, **kwargs):
for x in args
print x
Which requires at least three arguments, and supports variable numbers of other arguments and keyword arguments.
The [:-1]
removes the last element. Instead of
a[3:-1]
write
a[3:]

NumPy slicing is an extension of that. The NumPy tutorial has some coverage: Indexing, Slicing and Iterating.
AutoFocus worked best for me. I needed to change some text to an input with that text on double click so this is what I ended up with:
<input autoFocus onFocus={this.setCaretToEnd} value={this.state.editTodo.value} onDoubleClick={this.updateTodoItem} />
NOTE: To fix the issue where React places the caret at the beginning of the text use this method:
setCaretToEnd(event) {
var originalText = event.target.value;
event.target.value = '';
event.target.value = originalText;
}

The main
function can have two parameters, argc
and argv
. argc
is an integer (int
) parameter, and it is the number of arguments passed to the program.
The program name is always the first argument, so there will be at least one argument to a program and the minimum value of argc
will be one. But if a program has itself two arguments the value of argc
will be three.
Parameter argv
points to a string array and is called the argument vector. It is a one dimensional string array of function arguments.
A simple answer:
To expand on the POSIX variables answer, note that you can do more interesting patterns. So for the case detailed here, you could simply do this:
tar -zxvf $1
cd ${1%.tar.*}
That will cut off the last occurrence of .tar.<something>.
More generally, if you wanted to remove the last occurrence of .<something>.<something-else> then
${1.*.*}
should work fine.
The link the above answer appears to be dead. Here's a great explanation of a bunch of the string manipulation you can do directly in Bash, from TLDP.

Your best bet is to use middleware to achieve logging you're looking for. You want to put your exception logging in one middleware and then handle your error pages displayed to the user in a different middleware. That allows separation of logic and follows the design Microsoft has laid out with the 2 middleware components. Here's a good link to Microsoft's documentation: Error Handling in ASP.Net Core
For your specific example, you may want to use one of the extensions in the StatusCodePage middleware or roll your own like this.
You can find an example here for logging exceptions: ExceptionHandlerMiddleware.cs
public void Configure(IApplicationBuilder app)
{
// app.UseErrorPage(ErrorPageOptions.ShowAll);
// app.UseStatusCodePages();
// app.UseStatusCodePages(context => context.HttpContext.Response.SendAsync("Handler, status code: " + context.HttpContext.Response.StatusCode, "text/plain"));
// app.UseStatusCodePages("text/plain", "Response, status code: {0}");
// app.UseStatusCodePagesWithRedirects("~/errors/{0}");
// app.UseStatusCodePagesWithRedirects("/base/errors/{0}");
// app.UseStatusCodePages(builder => builder.UseWelcomePage());
app.UseStatusCodePagesWithReExecute("/Errors/{0}"); // I use this version
// Exception handling logging below
app.UseExceptionHandler();
}
If you don't like that specific implementation, then you can also use ELM Middleware, and here are some examples: Elm Exception Middleware
public void Configure(IApplicationBuilder app)
{
app.UseStatusCodePagesWithReExecute("/Errors/{0}");
// Exception handling logging below
app.UseElmCapture();
app.UseElmPage();
}
If that doesn't work for your needs, you can always roll your own Middleware component by looking at their implementations of the ExceptionHandlerMiddleware and the ElmMiddleware to grasp the concepts for building your own.
It's important to add the exception handling middleware below the StatusCodePages middleware but above all your other middleware components. That way your Exception middleware will capture the exception, log it, then allow the request to proceed to the StatusCodePage middleware which will display the friendly error page to the user.
If you are a Vi user, you may open the file and remove the carriage return with:
:%s/\r//g
or with
:1,$ s/^M//
Note that you should type ^M by pressing ctrl-v and then ctrl-m.
1 is substantially different from 2 and 3, since it leaves the array in tact, whereas the other two leave it empty.
I'd say #3 is pretty wacky and probably less efficient, so forget that.
Which leaves you with #1 and #2, and they do not do the same thing, so one cannot be "better" than the other. If the array is large and you don't need to keep it, generally scope will deal with it (but see NOTE), so generally, #1 is still the clearest and simplest method. Shifting each element off will not speed anything up. Even if there is a need to free the array from the reference, I'd just go:
undef @Array;
when done.
Wrap the checkbox within a label
tag:
<label><input type="checkbox" name="checkbox" value="value">Text</label>
for
AttributeUse the for
attribute (match the checkbox id
):
<input type="checkbox" name="checkbox" id="checkbox_id" value="value">
<label for="checkbox_id">Text</label>
NOTE: ID must be unique on the page!
Since the other answers don't mention it, a label can include up to 1 input and omit the for
attribute, and it will be assumed that it is for the input within it.
Excerpt from w3.org (with my emphasis):
[The for attribute] explicitly associates the label being defined with another control. When present, the value of this attribute must be the same as the value of the id attribute of some other control in the same document. When absent, the label being defined is associated with the element's contents.
To associate a label with another control implicitly, the control element must be within the contents of the LABEL element. In this case, the LABEL may only contain one control element. The label itself may be positioned before or after the associated control.
Using this method has some advantages over for
:
No need to assign an id
to every checkbox (great!).
No need to use the extra attribute in the <label>
.
The input's clickable area is also the label's clickable area, so there aren't two separate places to click that can control the checkbox - only one, no matter how far apart the <input>
and actual label text are, and no matter what kind of CSS you apply to it.
Demo with some CSS:
label {
border:1px solid #ccc;
padding:10px;
margin:0 0 10px;
display:block;
}
label:hover {
background:#eee;
cursor:pointer;
}
_x000D_
<label><input type="checkbox" />Option 1</label>
<label><input type="checkbox" />Option 2</label>
<label><input type="checkbox" />Option 3</label>

Without the need to install the grep variant pcregrep, you can do multiline search with grep.
$ grep -Pzo "(?s)^(\s*)\N*main.*?{.*?^\1}" *.c
Explanation:
-P
activate perl-regexp for grep (a powerful extension of regular expressions)
-z
suppress newline at the end of line, substituting it for null character. That is, grep knows where end of line is, but sees the input as one big line.
-o
print only matching. Because we're using -z
, the whole file is like a single big line, so if there is a match, the entire file would be printed; this way it won't do that.
In regexp:
(?s)
activate PCRE_DOTALL
, which means that .
finds any character or newline
\N
find anything except newline, even with PCRE_DOTALL
activated
.*?
find .
in non-greedy mode, that is, stops as soon as possible.
^
find start of line
\1
backreference to the first group (\s*
). This is a try to find the same indentation of method.
As you can imagine, this search prints the main method in a C (*.c
) source file.
You can use justify-content: space-between
in .test
like so:
.test {_x000D_
display: flex;_x000D_
justify-content: space-between;_x000D_
width: 20rem;_x000D_
border: .1rem red solid;_x000D_
}
_x000D_
<div class="test">_x000D_
<button>test</button>_x000D_
<button>test</button>_x000D_
</div>
_x000D_
For those who want to use Bootstrap 4 can use justify-content-between
:
div {_x000D_
width: 20rem;_x000D_
border: .1rem red solid;_x000D_
}
_x000D_
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" rel="stylesheet" />_x000D_
<div class="d-flex justify-content-between">_x000D_
<button>test</button>_x000D_
<button>test</button>_x000D_
</div>

playORM can do it for you using S-SQL(Scalable SQL) which just adds partitioning such that you can do joins within partitions.
GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH
. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:
export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH
Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).
timeObject.setSeconds(timeObject.getSeconds() + 10)
You can write a PL/SQL function to return that cursor (or you could put that function in a package if you have more code related to this):
CREATE OR REPLACE FUNCTION get_allitems
RETURN SYS_REFCURSOR
AS
my_cursor SYS_REFCURSOR;
BEGIN
OPEN my_cursor FOR SELECT * FROM allitems;
RETURN my_cursor;
END get_allitems;
This will return the cursor.
Make sure not to put your SELECT
-String into quotes in PL/SQL when possible. Putting it in strings means that it can not be checked at compile time, and that it has to be parsed whenever you use it.
If you really need to use dynamic SQL you can put your query in single quotes:
OPEN my_cursor FOR 'SELECT * FROM allitems';
This string has to be parsed whenever the function is called, which will usually be slower and hides errors in your query until runtime.
Make sure to use bind-variables where possible to avoid hard parses:
OPEN my_cursor FOR 'SELECT * FROM allitems WHERE id = :id' USING my_id;
Try this instead.

Instead of forcing an F5 keypress when you're just trying to get the page to postback, you can call a postback based on a JS event (even mousemove or timer_tick if you want it to fire all the time). Use the code at http://weblogs.asp.net/mnolton/archive/2003/06/04/8260.aspx as a reference.
You can see this error in VS 2008 if you have a project in your solution that references an assembly that cannot be found. This could happen if the assembly comes from another project that is not part of your solution but should be. In this case simply adding the correct project to the solution will solve it.
Check the References section of each project in your solution. If any of them has a reference with an red x next to it, then it you have found your problem. That assembly reference cannot be found by the solution.
The error message is a bit confusing but I've seen this many times.
I will side with nategood's answer as it is complete and it seemed to have please your needs. Though, I would like to add a comment on identifying multiple (1 or more) resource that way:
http://our.api.com/Product/101404,7267261
In doing so, you:
Complexify the clients
by forcing them to interpret your response as an array, which to me is counter intuitive if I make the following request: http://our.api.com/Product/101404
Create redundant APIs with one API for getting all products and the one above for getting 1 or many. Since you shouldn't show more than 1 page of details to a user for the sake of UX, I believe having more than 1 ID would be useless and purely used for filtering the products.
It might not be that problematic, but you will either have to handle this yourself server side by returning a single entity (by verifying if your response contains one or more) or let clients manage it.
Example
I want to order a book from Amazing. I know exactly which book it is and I see it in the listing when navigating for Horror books:
After selecting the second book, I am redirected to a page detailing the book part of a list:
--------------------------------------------
Book #1
--------------------------------------------
Title: The return of the amazing monster
Summary:
Pages:
Publisher:
--------------------------------------------
Or in a page giving me the full details of that book only?
---------------------------------
The return of the amazing monster
---------------------------------
Summary:
Pages:
Publisher:
---------------------------------
My Opinion
I would suggest using the ID in the path variable when unicity is guarantied when getting this resource's details. For example, the APIs below suggest multiple ways to get the details for a specific resource (assuming a product has a unique ID and a spec for that product has a unique name and you can navigate top down):
/products/{id}
/products/{id}/specs/{name}
The moment you need more than 1 resource, I would suggest filtering from a larger collection. For the same example:
/products?ids=
Of course, this is my opinion as it is not imposed.
Code ${1:-/dev/stdin}
will just understand first argument, so, how about this.
ARGS='$*'
if [ -z "$*" ]; then
ARGS='-'
fi
eval "cat -- $ARGS" | while read line
do
echo "$line"
done
If you want to stick with Jquery's .load() method, add something unique to the URL like a JavaScript timestamp. "+new Date().getTime()". Notice I had to add an "&time=" so it does not alter your pid variable.
$('#searchButton').click(function() {
$('#inquiry').load('/portal/?f=searchBilling&pid=' + $('#query').val()+'&time='+new Date().getTime());
});
Or just do that:
var app = req.app
inside the Middleware you are using for these routes. Like that:
router.use( (req,res,next) => {
app = req.app;
next();
});
You are printing a formatted string. The {0} means to insert the first parameter following the format string; in this case the value associated with the key "rtf".
For String.Format, which is similar, if you had something like
// Format string {0} {1}
String.Format("This {0}. The value is {1}.", "is a test", 42 )
you'd create a string "This is a test. The value is 42".
You can also use expressions, and print values out multiple times:
// Format string {0} {1} {2}
String.Format("Fib: {0}, {0}, {1}, {2}", 1, 1+1, 1+2)
yielding "Fib: 1, 1, 2, 3"
See more at http://msdn.microsoft.com/en-us/library/txafckwd.aspx, which talks about composite formatting.

}
class Test {
System.out.println(Tax.NONE); //Just an example.

if use Inline CSS you use
<img src="http://img705.imageshack.us/img705/119/original120x75.png" style="height:100px;width:100px;" alt="705"/>
Otherwise you can use class properties which related with a separate css file (styling your website) as like In CSS File
.imgSize {height:100px;width:100px;}
In HTML File
<img src="http://img705.imageshack.us/img705/119/original120x75.png" style="height:100px;width:100px;" alt="705"/>
Trying on a different browser(chrome) worked for me and clearing cache on firefox cleared the issue.

Use textcleaner library to remove stopwords from your data.
Follow this link:https://yugantm.github.io/textcleaner/documentation.html#remove_stpwrds
Follow these steps to do so with this library.
pip install textcleaner
After installing:
import textcleaner as tc
data = tc.document(<file_name>)
#you can also pass list of sentences to the document class constructor.
data.remove_stpwrds() #inplace is set to False by default
Use above code to remove the stop-words.
this will open the file with the default windows program (notepad if you haven't changed it);
Process.Start(@"c:\myfile.txt")
You access the property in the wrong way. With the $this->$my_value = ..
syntax, you set the property with the name of the value in $my_value. What you want is $this->my_value = ..
$var = "my_value";
$this->$var = "test";
is the same as
$this->my_value = "test";
To fix a few things from your example, the code below is a better aproach
class my_class {
public $my_value = array();
function __construct ($value) {
$this->my_value[] = $value;
}
function set_value ($value) {
if (!is_array($value)) {
throw new Exception("Illegal argument");
}
$this->my_value = $value;
}
function add_value($value) {
$this->my_value = $value;
}
}
$a = new my_class ('a');
$a->my_value[] = 'b';
$a->add_value('c');
$a->set_value(array('d'));
This ensures, that my_value won't change it's type to string or something else when you call set_value. But you can still set the value of my_value direct, because it's public. The final step is, to make my_value private and only access my_value over getter/setter methods
Open the mysql terminal:
el@apollo:~$ mysql -u root -pthepassword yourdb
mysql>
Drop the function if it already exists
mysql> drop function if exists myfunc;
Query OK, 0 rows affected, 1 warning (0.00 sec)
Create the function
mysql> create function hello(id INT)
-> returns CHAR(50)
-> return 'foobar';
Query OK, 0 rows affected (0.01 sec)
Create a simple table to test it out with
mysql> create table yar (id INT);
Query OK, 0 rows affected (0.07 sec)
Insert three values into the table yar
mysql> insert into yar values(5), (7), (9);
Query OK, 3 rows affected (0.04 sec)
Records: 3 Duplicates: 0 Warnings: 0
Select all the values from yar, run our function hello each time:
mysql> select id, hello(5) from yar;
+------+----------+
| id | hello(5) |
+------+----------+
| 5 | foobar |
| 7 | foobar |
| 9 | foobar |
+------+----------+
3 rows in set (0.01 sec)
Verbalize and internalize what just happened:
You created a function called hello which takes one parameter. The parameter is ignored and returns a CHAR(50)
containing the value 'foobar'. You created a table called yar and added three rows to it. The select statement runs the function hello(5)
for each row returned by yar.
I had this issue, and I set the Locale

, then it work.

In the end, both do the same thing. There are some differences in code: Web Services doesn't add a Root namespace of project, but Service Reference adds service classes to the namespace of the project. The ServiceSoapClient
class gets a different naming, which is not important. In working with TFS I'd rather use Service Reference because it works better with source control. Both work with SOAP protocols.
I find it better to use the Service Reference because it is new and will thus be better maintained.
With 4.0, you will need to manage this yourself by setting the culture for each thread as Alexei describes. But with 4.5, you can define a culture for the appdomain and that is the preferred way to handle this. The relevant apis are CultureInfo.DefaultThreadCurrentCulture and CultureInfo.DefaultThreadCurrentUICulture.
This is the autofilter macro you could base a function off of:
Selection.AutoFilter
ActiveSheet.Range("$A$1:$A$10").AutoFilter Field:=1, Criteria1:="=*-*", Operator:=xlAnd
Selection.AutoFilter
I use this autofilter function to delete matching rows:
Public Sub FindDelete(sCol As String, vSearch As Variant)
'Simple find and Delete
Dim lLastRow As Integer
Dim rng As Range
Dim rngDelete As Range
Range(sCol & 1).Select
[2:2].Insert
Range(sCol & 2) = "temp"
With ActiveSheet
.usedrange
lLastRow = .Cells.SpecialCells(xlCellTypeLastCell).Row
Set rng = Range(sCol & 2, Cells(lLastRow, sCol))
rng.AutoFilter Field:=1, Criteria1:=vSearch, Operator:=xlAnd
Set rngDelete = rng.SpecialCells(xlCellTypeVisible)
rng.AutoFilter
rngDelete.EntireRow.Delete
.usedrange
End With
End Sub
call it like:
call FindDelete "A", "=*-*"
It's saved me a lot of work. Good luck!
You need to download the Native Development Kit.
It means that somewhere in your code, you are calling a function which in turn calls another function and so forth, until you hit the call stack limit.
This is almost always because of a recursive function with a base case that isn't being met.
Consider this code...
(function a() {
a();
})();
Here is the stack after a handful of calls...
As you can see, the call stack grows until it hits a limit: the browser hardcoded stack size or memory exhaustion.
In order to fix it, ensure that your recursive function has a base case which is able to be met...
(function a(x) {
// The following condition
// is the base case.
if ( ! x) {
return;
}
a(--x);
})(10);
The C++ over-engineering mindset is already well accounted for in the other answers here. Here's my attempt at doing it with a C, keep-it-simple-ffs mindset:
unsigned char x = 0xF; // binary: 00001111
$timeFirst = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;
You will then be able to use the seconds to find minutes, hours, days, etc.
Yes, it is recommended to put the GA code in the footer anyway, as the page shouldnt count as a page visit until its read all the markup.

print(str(server_ip))
Every thing is fine.
i just placed call permissions tag before application tag in manifest file
and now every thing is working fine.
From here:
One way to conserve system resources is to configure idle time-out settings for the worker processes in an application pool. When these settings are configured, a worker process will shut down after a specified period of inactivity. The default value for idle time-out is 20 minutes.
Also check Why is the IIS default app pool recycle set to 1740 minutes?
If you have a just a few sites on your server and you want them to always load fast then set this to zero. Otherwise, when you have 20 minutes without any traffic then the app pool will terminate so that it can start up again on the next visit. The problem is that the first visit to an app pool needs to create a new w3wp.exe worker process which is slow because the app pool needs to be created, ASP.NET or another framework needs to be loaded, and then your application needs to be loaded. That can take a few seconds. Therefore I set that to 0 every chance I have, unless it’s for a server that hosts a lot of sites that don’t always need to be running.
here is another solution...
System.IO.Stream st = new System.IO.StreamReader (picturePath).BaseStream;
byte[] buffer = new byte[4096];
System.IO.MemoryStream m = new System.IO.MemoryStream ();
while (st.Read (buffer,0,buffer.Length) > 0) {
m.Write (buffer, 0, buffer.Length);
}
imgView.Tag = m.ToArray ();
st.Close ();
m.Close ();
hope it helps!
Ok, I don't normally answer my own questions but after a bit of tinkering, I have figured out definitively how Oracle stores the result of a DATE subtraction.
When you subtract 2 dates, the value is not a NUMBER datatype (as the Oracle 11.2 SQL Reference manual would have you believe). The internal datatype number of a DATE subtraction is 14, which is a non-documented internal datatype (NUMBER is internal datatype number 2). However, it is actually stored as 2 separate two's complement signed numbers, with the first 4 bytes used to represent the number of days and the last 4 bytes used to represent the number of seconds.
An example of a DATE subtraction resulting in a positive integer difference:
select date '2009-08-07' - date '2008-08-08' from dual;
Results in:
DATE'2009-08-07'-DATE'2008-08-08'
---------------------------------
364
select dump(date '2009-08-07' - date '2008-08-08') from dual;
DUMP(DATE'2009-08-07'-DATE'2008
-------------------------------
Typ=14 Len=8: 108,1,0,0,0,0,0,0
Recall that the result is represented as a 2 seperate two's complement signed 4 byte numbers. Since there are no decimals in this case (364 days and 0 hours exactly), the last 4 bytes are all 0s and can be ignored. For the first 4 bytes, because my CPU has a little-endian architecture, the bytes are reversed and should be read as 1,108 or 0x16c, which is decimal 364.
An example of a DATE subtraction resulting in a negative integer difference:
select date '1000-08-07' - date '2008-08-08' from dual;
Results in:
DATE'1000-08-07'-DATE'2008-08-08'
---------------------------------
-368160
select dump(date '1000-08-07' - date '2008-08-08') from dual;
DUMP(DATE'1000-08-07'-DATE'2008-08-0
------------------------------------
Typ=14 Len=8: 224,97,250,255,0,0,0,0
Again, since I am using a little-endian machine, the bytes are reversed and should be read as 255,250,97,224 which corresponds to 11111111 11111010 01100001 11011111. Now since this is in two's complement signed binary numeral encoding, we know that the number is negative because the leftmost binary digit is a 1. To convert this into a decimal number we would have to reverse the 2's complement (subtract 1 then do the one's complement) resulting in: 00000000 00000101 10011110 00100000 which equals -368160 as suspected.
An example of a DATE subtraction resulting in a decimal difference:
select to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS'
- to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS') from dual;
TO_DATE('08/AUG/200414:00:00','DD/MON/YYYYHH24:MI:SS')-TO_DATE('08/AUG/20048:00:
--------------------------------------------------------------------------------
.25
The difference between those 2 dates is 0.25 days or 6 hours.
select dump(to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS')
- to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS')) from dual;
DUMP(TO_DATE('08/AUG/200414:00:
-------------------------------
Typ=14 Len=8: 0,0,0,0,96,84,0,0
Now this time, since the difference is 0 days and 6 hours, it is expected that the first 4 bytes are 0. For the last 4 bytes, we can reverse them (because CPU is little-endian) and get 84,96 = 01010100 01100000 base 2 = 21600 in decimal. Converting 21600 seconds to hours gives you 6 hours which is the difference which we expected.
Hope this helps anyone who was wondering how a DATE subtraction is actually stored.
You get the syntax error because the date math does not return a NUMBER, but it returns an INTERVAL:
SQL> SELECT DUMP(SYSDATE - start_date) from test;
DUMP(SYSDATE-START_DATE)
--------------------------------------
Typ=14 Len=8: 188,10,0,0,223,65,1,0
You need to convert the number in your example into an INTERVAL first using the NUMTODSINTERVAL Function
For example:
SQL> SELECT (SYSDATE - start_date) DAY(5) TO SECOND from test;
(SYSDATE-START_DATE)DAY(5)TOSECOND
----------------------------------
+02748 22:50:04.000000
SQL> SELECT (SYSDATE - start_date) from test;
(SYSDATE-START_DATE)
--------------------
2748.9515
SQL> select NUMTODSINTERVAL(2748.9515, 'day') from dual;
NUMTODSINTERVAL(2748.9515,'DAY')
--------------------------------
+000002748 22:50:09.600000000
SQL>
Based on the reverse cast with the NUMTODSINTERVAL() function, it appears some rounding is lost in translation.
It is now possible with the HTML5 webapp manifest. See below.
Original answer:
You can't lock a website or a web application in a specific orientation. It goes against the natural behaviour of the device.
You can detect the device orientation with CSS3 media queries like this:
@media screen and (orientation:portrait) {
// CSS applied when the device is in portrait mode
}
@media screen and (orientation:landscape) {
// CSS applied when the device is in landscape mode
}
Or by binding a JavaScript orientation change event like this:
document.addEventListener("orientationchange", function(event){
switch(window.orientation)
{
case -90: case 90:
/* Device is in landscape mode */
break;
default:
/* Device is in portrait mode */
}
});
Update on November 12, 2014: It is now possible with the HTML5 webapp manifest.
As explained on html5rocks.com, you can now force the orientation mode using a manifest.json
file.
You need to include those line into the json file:
{
"display": "standalone", /* Could be "fullscreen", "standalone", "minimal-ui", or "browser" */
"orientation": "landscape", /* Could be "landscape" or "portrait" */
...
}
And you need to include the manifest into your html file like this:
<link rel="manifest" href="manifest.json">
Not exactly sure what the support is on the webapp manifest for locking orientation mode, but Chrome is definitely there. Will update when I have the info.

I'm getting best results to put jQuery dialog in the center of browser's window with:

Eclipse failed to connect to SVN https repositories (should also apply to any app using SSL/TLS).
svn: E175002: Connection has been shutdown: javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: Certificates does not conform to algorithm constraints
The issue was caused by latest Java 8 OpenJDK update that disabled MD5 related algorithms. As a workaround until new certificates are issued (if ever), change the following keys at java.security file
WARNING
Keep in mind that this could have security implications as disabled algorithms are considered weak. As an alternative, the workaround can be applied on a JVM basis by a command line option to use an external java.security file with this changes, e.g.:
java -Djava.security.properties=/etc/sysconfig/noMD5.java.security
For Eclipse, add a line on eclipse.ini below -vmargs
-Djava.security.properties=/etc/sysconfig/noMD5.java.security
jdk.certpath.disabledAlgorithms=MD2, MD5, RSA keySize < 1024

jdk.tls.disabledAlgorithms=SSLv3, RC4, DH keySize < 768
java.security file is located in linux 64 at /usr/lib64/jvm/java/jre/lib/security/java.security
While a similar answer has already been sort of posted, I think the reason to use the new PrimitiveIterator.OfInt was not clear. A good solution is to use Java 8 PrimitiveIterator since it's specialized for primitive int types (and avoids the extra boxing/unboxing penalty):
int[] arr = {1,2,3};
// If you use Iterator<Integer> here as type then you can't get the actual benefit of being able to use nextInt() later
PrimitiveIterator.OfInt iterator = Arrays.stream(arr).iterator();
while (iterator.hasNext()) {
System.out.println(iterator.nextInt());
// Use nextInt() instead of next() here to avoid extra boxing penalty
}

The flaw with the selected answer is that it unnecessarily assumes order in webDriver.getWindowHandles()
. The getWindowHandles()
method returns a Set
, which does not guarantee order.
I used the following code to change tabs, which does not assume any ordering.
String currentTabHandle = driver.getWindowHandle();
String newTabHandle = driver.getWindowHandles()
.stream()
.filter(handle -> !handle.equals(currentTabHandle ))
.findFirst()
.get();
driver.switchTo().window(newTabHandle);
Sometimes it may be required to execute the update atomically that is using one update request to the database without reading it first.
Also get
-set attribute
-save
may cause problems if such updates may be done concurrently or if you need to set the new value based on the old field value.
In such cases query expressions together with update
may by useful:
TemperatureData.objects.filter(id=1).update(value=F('value') + 1)
You can show changes that have been staged with the --cached
flag:
$ git diff --cached
In more recent versions of git, you can also use the --staged
flag (--staged
is a synonym for --cached
):
$ git diff --staged
For me this error was due to the command prompt, which was not running under administrator privileges. You need to right click on the command prompt and say "Run as administrator".
You need administrator role to install or uninstall a service.
Imagine the DOM (HTML page) as a tree right. The HTML elements are the nodes of this tree.
The append()
adds a new node to the child
of the node you called it on.
Example:$("#mydiv").append("<p>Hello there</p>")
creates a child node <p> to <div>
The after()
adds a new node as a sibling or at the same level or child to the parent of the node you called it on.

Date.prototype.toString = function() {
var offsetDate, offsetTime;
offsetTime = this.timezoneOffset * 60 * 1000;
offsetDate = new Date(this.getTime() - offsetTime);

You can use lftp interactively in a shell script so the password not saved in .bash_history or similar by doing the following:
vi test_script.sh
Add the following to your file:
#!/bin/sh
HOST=<yourhostname>
USER=<someusername>
PASSWD=<yourpasswd>
cd <base directory for your put file>
lftp<<END_SCRIPT
open sftp://$HOST
user $USER $PASSWD
put local-file.name
bye
END_SCRIPT
And write/quit the vi editor after you edit the host, user, pass, and directory for your put file typing :wq
.Then make your script executable chmod +x test_script.sh
and execute it ./test_script.sh
.

I think it will be sometime before we get to see access to the NFC as the pure security side of it like for example being able to walk past somebody brush past them and & get your phone to the zap the card details or simply Wave your phone over someone's wallet which They left on the desk.
I think the first step is for Apple to talk to banks and find more ways of securing cards and NFC before This will be allowed
Suppose you have mulitple record for same date or leave_type but different id and you want the maximum no of id for same date or leave_type as i also sucked with this issue, so Yes you can do it with the following query:

select max(id) from table_name where employee_no='123' and leave_type='5'

Create custom facebook button and change visability on native facebook button:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<Button
android:id="@+id/facebookView"
android:layout_width="300dp"
android:layout_height="48dp"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="12dp"
android:background="@drawable/btn_frame"
android:gravity="center"
android:text="@string/Sign_in_facebook_button"
android:textColor="@color/colorAccent" />
<com.facebook.login.widget.LoginButton
android:id="@+id/facebookButton"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="invisible"
android:layout_marginBottom="12dp" />
</LinearLayout>
Add listener to your fake button and simulate click:
facebookView.setOnClickListener(this);
@Override
public void onClick(View v) {
if (v.getId() == R.id.facebookView){
facebookButton.performClick();
}
}
If you can afford to tie yourself to just Lollipop and later, this seems to do the trick:
import android.transition.Slide;
import android.util.Log;
import android.view.Gravity;
.
.
.
f = new MyFragment();
f.setEnterTransition(new Slide(Gravity.END));
f.setExitTransition(new Slide(Gravity.START));
getFragmentManager()
.beginTransaction()
.replace(R.id.content, f, FRAG_TAG) // FRAG_TAG is the tag for your fragment
.commit();
Kotlin version:
f = MyFragment().apply {
enterTransition = Slide(Gravity.END)
exitTransition = Slide(Gravity.START)
}
fragmentManager
.beginTransaction()
.replace(R.id.content, f, FRAG_TAG) // FRAG_TAG is the tag for your fragment
.commit();
Hope this helps.
A more important performance difference is that an HTTPS session is ketp open while the user is connected. An HTTP 'session' lasts only for a single item request.
It you are running a site with a large number of concurrent users, expect to buy a lot of memory.
You can always use Request.QueryString
collection like Web forms, but you can also make MVC handle them and pass them as parameters. This is the suggested way as it's easier and it will validate input data type automatically.
Isn't

Try looking at the return value of execute

on success, and FALSE
on failure.
In comprehension, the nested lists iteration should follow the same order than the equivalent imbricated for loops.
To understand, we will take a simple example from NLP. You want to create a list of all words from a list of sentences where each sentence is a list of words.
>>> list_of_sentences = [['The','cat','chases', 'the', 'mouse','.'],['The','dog','barks','.']]
>>> all_words = [word for sentence in list_of_sentences for word in sentence]
>>> all_words
['The', 'cat', 'chases', 'the', 'mouse', '.', 'The', 'dog', 'barks', '.']
To remove the repeated words, you can use a set {} instead of a list []
>>> all_unique_words = list({word for sentence in list_of_sentences for word in sentence}]
>>> all_unique_words
['.', 'dog', 'the', 'chase', 'barks', 'mouse', 'The', 'cat']
or apply list(set(all_words))
>>> all_unique_words = list(set(all_words))
['.', 'dog', 'the', 'chases', 'barks', 'mouse', 'The', 'cat']

The .git
at the end of the repository name is just a convention. Typically, on git servers repositories are kept in directories named project.git
. The git client and protocol honours this convention by testing for project.git
when only project
is specified.
git://[email protected]/peter/first_app.git
is not a valid git url. git repositories can be identified and accessed via various url schemes specified here. [email protected]:peter/first_app.git
is the ssh
url mentioned on that page.
git
is flexible. It allows you to track your local branch against almost any branch of any repository. While master
(your local default branch) tracking origin/master
(the remote default branch) is a popular situation, it is not universal. Many a times you may not want to do that. This is why the first git push
is so verbose. It tells git what to do with the local master
branch when you do a git pull
or a git push
.
The default for git push
and git pull
is to work with the current branch's remote. This is a better default than origin master. The way git push determines this is explained here.
git
is fairly elegant and comprehensible but there is a learning curve to walk through.
"A destructor wouldn't even help you here. It's the event listeners themselves that still reference your object, so it would not be able to get garbage-collected before they are unregistered."
Not so. The purpose of a destructor is to allow the item that registered the listeners to unregister them. Once an object has no other references to it, it will be garbage collected.
For instance, in AngularJS, when a controller is destroyed, it can listen for a destroy event and respond to it. This isn't the same as having a destructor automatically called, but it's close, and gives us the opportunity to remove listeners that were set when the controller was initialized.
// Set event listeners, hanging onto the returned listener removal functions
function initialize() {
$scope.listenerCleanup = [];
$scope.listenerCleanup.push( $scope.$on( EVENTS.DESTROY, instance.onDestroy) );
$scope.listenerCleanup.push( $scope.$on( AUTH_SERVICE_RESPONSES.CREATE_USER.SUCCESS, instance.onCreateUserResponse ) );
$scope.listenerCleanup.push( $scope.$on( AUTH_SERVICE_RESPONSES.CREATE_USER.FAILURE, instance.onCreateUserResponse ) );
}
// Remove event listeners when the controller is destroyed
function onDestroy(){
$scope.listenerCleanup.forEach( remove => remove() );
}
fixed positioning alone should have fixed that problem but another good workaround to avoid this issue is to place your modal divs or elements at the bottom of the page not within your sites layout. Most modal plugins give their modal positioning absolute to allow the user keep main page scrolling.
<html>
<body>
<!-- Put all your page layouts and elements
<!-- Let the last element be the modal elemment -->
<div id="myModals">
...
</div>
</body>
</html>
Here is a solution without eval nor $() nor `` :

You can set its visibility
property to hidden
.
Here is a little demonstration, where one button is used to toggle the other one:
<input type="button" id="toggler" value="Toggler" onClick="action();" />
<input type="button" id="togglee" value="Togglee" />
<script>
var hidden = false;
function action() {
hidden = !hidden;
if(hidden) {
document.getElementById('togglee').style.visibility = 'hidden';
} else {
document.getElementById('togglee').style.visibility = 'visible';
}
}
</script>
You can use the usual Python package structure to divide your App into multiple modules, see the Flask docs.
However,
Flask uses a concept of blueprints for making application components and supporting common patterns within an application or across applications.
You can create a sub-component of your app as a Blueprint in a separate file:
simple_page = Blueprint('simple_page', __name__, template_folder='templates')
@simple_page.route('/<page>')
def show(page):
# stuff
And then use it in the main part:
from yourapplication.simple_page import simple_page
app = Flask(__name__)
app.register_blueprint(simple_page)
Blueprints can also bundle specific resources: templates or static files. Please refer to the Flask docs for all the details.
You can use an out parameter instead of the return value if you want both a result set and a return value
CREATE PROCEDURE proc_name
@param int out
AS
BEGIN
SET @param = value
SELECT ... FROM [Table] WHERE Condition
END
GO
Sounds like you're looking for the time_ago_in_words
method (or distance_of_time_in_words
), from ActiveSupport. Call it like this:
<%= time_ago_in_words(timestamp) %>
Was running into this problem using several different localhost servers. Finally got my app up and running on the phone in seconds just by using the Python simple server. It only takes a few seconds so is worth a try before getting into any more complicated solutions. First, make sure you have Python installed. cmd+r
and type python
for Windows or $ python --version
in mac terminal.
Next:
cd <your project root>
$ python -m SimpleHTTPServer 8000
Then just find the address of your host machine on the network, I used System Preferences/Sharing
on mac to find it. Tap that into your Android device and should load your index.html
and you should be good.
If not then the problem is something else and you may want to look into some of the other suggested solutions. Good luck!
* EDIT *
Another quick solution to try if you're using Chrome is the Web Server for Chrome extension. I found it a quick and super easy way to get access to localhost on my phone. Just make sure to check Accessible to local network
under the Options
and it should work on your cell without any problem.

With .NET 4.5 you currently could use System.Net.Http namespace. Below the example for uploading single file using multipart form data.
using System;
using System.IO;
using System.Net.Http;
namespace HttpClientTest
{
class Program
{
static void Main(string[] args)
{
var client = new HttpClient();
var content = new MultipartFormDataContent();
content.Add(new StreamContent(File.Open("../../Image1.png", FileMode.Open)), "Image", "Image.png");
content.Add(new StringContent("Place string content here"), "Content-Id in the HTTP");
var result = client.PostAsync("https://hostname/api/Account/UploadAvatar", content);
Console.WriteLine(result.Result.ToString());
}
}
}
Response.write() don't give formatted output. The latter one allows you to write formatted output.
Response.write - it writes the text stream Response.output.write - it writes the HTTP Output Stream.
Starting from Steve's answer the ternary operator can be used:
public int compareTo(Person other) {
int f = firstName.compareTo(other.firstName);
int l = lastName.compareTo(other.lastName);
return f != 0 ? f : l != 0 ? l : Integer.compare(age, other.age);
}
If you are working in some IDE like Eclipse or NetBeans, you should have that a.txt
file in the root directory of your project. (and not in the folder where your .class
files are built or anywhere else)
If not, you should specify the absolute path to that file.
Edit:
You would put the .txt
file in the same place with the .class
(usually also the .java
file because you compile in the same folder) compiled files if you compile it by hand with javac
. This is because it uses the relative path and the path tells the JVM the path where the executable file is located.
If you use some IDE, it will generate the compiled files for you using a Makefile or something similar for Windows and will consider it's default file structure, so he knows that the relative path begins from the root folder of the project.
This gives you fixed length for the lines, but works great. The lines lengths are controlled by adding or taking '\00a0' (unicode space).
h1:before, h1:after {_x000D_
content:'\00a0\00a0\00a0\00a0';_x000D_
text-decoration: line-through;_x000D_
margin: auto 0.5em;_x000D_
}

I haven't tried it myself, but I would suggest using Jest's toThrow assertion. So I guess your example would look something like this:
it('should throw Error with message \'UNKNOWN ERROR\' when no parameters were passed', (t) => {
const error = t.throws(() => {
throwError();
}, TypeError);
expect(t).toThrowError('UNKNOWN ERROR');
//or
expect(t).toThrowError(TypeError);
});
Again, I haven't test it, but I think it should work.
Gson 1.6 now includes a low-level streaming API and a new parser which is actually faster than Jackson.
Just to save some of you time...
On my Galaxy S v.2.3.3 Shared Preferences are not stored in:/data/data/YOUR_PACKAGE_NAME/shared_prefs/YOUR_PREFS_NAME.xml
but are now located in: /dbdata/databases/YOUR_PACKAGE_NAME/shared_prefs/YOUR_PREFS_NAME.xml
I believe they changed this in 2.3
I got this error but it is resolved interesting. As first, i got this error at api level 17. When i call a thread (AsyncTask or others) without progress dialog then i call an other thread method again using progress dialog, i got that crash and the reason is about usage of progress dialog.
In my case, there are two results that;
show();
method of progress dialog before first thread starts then i took dismiss();
method of progress dialog before last thread ends. So :
ProgresDialog progressDialog = new ...
//configure progressDialog
progressDialog.show();
start firstThread {
...
}
...
start lastThread {
...
}
//be sure to finish threads
progressDialog.dismiss();
[Edit] There's another solution not mentioned yet, and it seems to outperform the others given so far in most cases.
Use string.translate to replace all valid characters in the string, and see if we have any invalid ones left over. This is pretty fast as it uses the underlying C function to do the work, with very little python bytecode involved.
Obviously performance isn't everything - going for the most readable solutions is probably the best approach when not in a performance critical codepath, but just to see how the solutions stack up, here's a performance comparison of all the methods proposed so far. check_trans is the one using the string.translate method.
Test code:
import string, re, timeit
pat = re.compile('[\w-]*$')
pat_inv = re.compile ('[^\w-]')
allowed_chars=string.ascii_letters + string.digits + '_-'
allowed_set = set(allowed_chars)
trans_table = string.maketrans('','')
def check_set_diff(s):
return not set(s) - allowed_set
def check_set_all(s):
return all(x in allowed_set for x in s)
def check_set_subset(s):
return set(s).issubset(allowed_set)
def check_re_match(s):
return pat.match(s)
def check_re_inverse(s): # Search for non-matching character.
return not pat_inv.search(s)
def check_trans(s):
return not s.translate(trans_table,allowed_chars)
test_long_almost_valid='a_very_long_string_that_is_mostly_valid_except_for_last_char'*99 + '!'
test_long_valid='a_very_long_string_that_is_completely_valid_' * 99
test_short_valid='short_valid_string'
test_short_invalid='/$%$%&'
test_long_invalid='/$%$%&' * 99
test_empty=''
def main():
funcs = sorted(f for f in globals() if f.startswith('check_'))
tests = sorted(f for f in globals() if f.startswith('test_'))
for test in tests:
print "Test %-15s (length = %d):" % (test, len(globals()[test]))
for func in funcs:
print " %-20s : %.3f" % (func,
timeit.Timer('%s(%s)' % (func, test), 'from __main__ import pat,allowed_set,%s' % ','.join(funcs+tests)).timeit(10000))
print
if __name__=='__main__': main()

The translate approach seems best in most cases, dramatically so with long valid strings, but is beaten out by regexes in test_long_invalid (Presumably because the regex can bail out immediately, but translate always has to scan the whole string). The set approaches are usually worst, beating regexes only for the empty string case.
Using all(x in allowed_set for x in s) performs well if it bails out early, but can be bad if it has to iterate through every character. isSubSet and set difference are comparable, and are consistently proportional to the length of the string regardless of the data.
There's a similar difference between the regex methods matching all valid characters and searching for invalid characters. Matching performs a little better when checking for a long, but fully valid string, but worse for invalid characters near the end of the string.
The problem is that you are trying to access resources (in this case, strings) using getResources().getString(), which will try to get the resources from the Activity. See this source code of the Fragment class:
/**
* Return <code>getActivity().getResources()</code>.
*/
final public Resources getResources() {
if (mHost == null) {
throw new IllegalStateException("Fragment " + this + " not attached to Activity");
}
return mHost.getContext().getResources();
}
mHost
is the object that holds your Activity.
Because the Activity might not be attached, your getResources() call will throw an Exception.
The accepted solution IMHO is not the way to go as you are just hiding the problem. The correct way is just to get the resources from somewhere else that is always guaranteed to exist, like the application context:
youApplicationObject.getResources().getString(...)
Generally speaking, a software product isn't your "property already", as you said in the comment. Most of the times (I won't be irresponsible to say anything in open), it's licensed to you. A license to use some thing is not the same thing as owning (property rights) that very same thing.
That's because there are authorship, copyright, intellectual property rights applicable to it. I don't know how things work in United States (or in your country), but it's generally accepted that the work of a mind, a creative work, must not be changed in its nature as such to make the expression of art to be different than that expression that the author intended. That applies for example, in some cases, to architectural work (in most countries, you can't change the appearance of a building to "desfigure" the work of art of the architect, without his prior consent). Exceptions are made, obviously, when the author expressly authorizes such changes (e.g., Creative Commons licenses, open source licenses etc.).
Anyway, that's why you see in most EULAs the typical sentence: "this software is licensed, not sold". That's the purpose and reason why.
Now that you understand the reasons why you can't wander around changing other people's art, let me be technical.
There are possible ways to decompile Java programs. You can use dex2jar
, it provides a somewhat good start for you to start looking for things and changes. And perhaps rebuild the code by mounting back the pieces together. Good luck, as most people obfuscate their codes to make that harder.
However, let me say that it's still forbidden to change programs, as I said above. And it's extremely unethical. It makes me sad that people do that with no scruples (not saying it's your case, just warning you). It shouldn't need people to be at the other side to understand that. Or maybe that's just me, who lives in a country where piracy is rampant.
The tools are always out there. But the conscience, unfortunately, not always.
edit: in case it isn't clear enough already, I do NOT approve the use of these programs. I use them myself to check how hard my own applications are to be reverse engineered. But I also think that explaning is always better than denial (better be here).
In Rails 3.2.18, :decimal turns into :integer when using SQLServer, but it works fine in SQLite. Switching to :float solved this issue for us.
The lesson learned is "always use homogeneous development and deployment databases!"
