My answer won't probably be useful to the writer of this question (I am 8 months late so not the right timing I guess) but I think it will probably be useful for many other developers that might come across this answer.
Today, I just released (in the name of my company) an HTML to POJO complete framework that you can use to map HTML to any POJO class with simply some annotations. The library itself is quite handy and features many other things all the while being very pluggable. You can have a look to it right here : https://github.com/whimtrip/jwht-htmltopojo
Imagine we need to parse the following html page :
<html>
<head>
<title>A Simple HTML Document</title>
</head>
<body>
<div class="restaurant">
<h1>A la bonne Franquette</h1>
<p>French cuisine restaurant for gourmet of fellow french people</p>
<div class="location">
<p>in <span>London</span></p>
</div>
<p>Restaurant n*18,190. Ranked 113 out of 1,550 restaurants</p>
<div class="meals">
<div class="meal">
<p>Veal Cutlet</p>
<p rating-color="green">4.5/5 stars</p>
<p>Chef Mr. Frenchie</p>
</div>
<div class="meal">
<p>Ratatouille</p>
<p rating-color="orange">3.6/5 stars</p>
<p>Chef Mr. Frenchie and Mme. French-Cuisine</p>
</div>
</div>
</div>
</body>
</html>
Let's create the POJOs we want to map it to :
public class Restaurant {
@Selector( value = "div.restaurant > h1")
private String name;
@Selector( value = "div.restaurant > p:nth-child(2)")
private String description;
@Selector( value = "div.restaurant > div:nth-child(3) > p > span")
private String location;
@Selector(
value = "div.restaurant > p:nth-child(4)"
format = "^Restaurant n\*([0-9,]+). Ranked ([0-9,]+) out of ([0-9,]+) restaurants$",
indexForRegexPattern = 1,
useDeserializer = true,
deserializer = ReplacerDeserializer.class,
preConvert = true,
postConvert = false
)
// so that the number becomes a valid number as they are shown in this format : 18,190
@ReplaceWith(value = ",", with = "")
private Long id;
@Selector(
value = "div.restaurant > p:nth-child(4)"
format = "^Restaurant n\*([0-9,]+). Ranked ([0-9,]+) out of ([0-9,]+) restaurants$",
// This time, we want the second regex group and not the first one anymore
indexForRegexPattern = 2,
useDeserializer = true,
deserializer = ReplacerDeserializer.class,
preConvert = true,
postConvert = false
)
// so that the number becomes a valid number as they are shown in this format : 18,190
@ReplaceWith(value = ",", with = "")
private Integer rank;
@Selector(value = ".meal")
private List<Meal> meals;
// getters and setters
}
And now the Meal
class as well :
public class Meal {
@Selector(value = "p:nth-child(1)")
private String name;
@Selector(
value = "p:nth-child(2)",
format = "^([0-9.]+)\/5 stars$",
indexForRegexPattern = 1
)
private Float stars;
@Selector(
value = "p:nth-child(2)",
// rating-color custom attribute can be used as well
attr = "rating-color"
)
private String ratingColor;
@Selector(
value = "p:nth-child(3)"
)
private String chefs;
// getters and setters.
}
We provided some more explanations on the above code on our github page.
For the moment, let's see how to scrap this.
private static final String MY_HTML_FILE = "my-html-file.html";
public static void main(String[] args) {
HtmlToPojoEngine htmlToPojoEngine = HtmlToPojoEngine.create();
HtmlAdapter<Restaurant> adapter = htmlToPojoEngine.adapter(Restaurant.class);
// If they were several restaurants in the same page,
// you would need to create a parent POJO containing
// a list of Restaurants as shown with the meals here
Restaurant restaurant = adapter.fromHtml(getHtmlBody());
// That's it, do some magic now!
}
private static String getHtmlBody() throws IOException {
byte[] encoded = Files.readAllBytes(Paths.get(MY_HTML_FILE));
return new String(encoded, Charset.forName("UTF-8"));
}

Hope this will help someone out there!
Also, you can use shelljs
plugin.
It's easy and it's cross-platform.
Install command:
npm install [-g] shelljs
What is shellJS
ShellJS is a portable (Windows/Linux/OS X) implementation of Unix shell commands on top of the Node.js API. You can use it to eliminate your shell script's dependency on Unix while still keeping its familiar and powerful commands. You can also install it globally so you can run it from outside Node projects - say goodbye to those gnarly Bash scripts!
An example of how it works:
var shell = require('shelljs');
if (!shell.which('git')) {
shell.echo('Sorry, this script requires git');
shell.exit(1);
}
// Copy files to release dir
shell.rm('-rf', 'out/Release');
shell.cp('-R', 'stuff/', 'out/Release');
// Replace macros in each .js file
shell.cd('lib');
shell.ls('*.js').forEach(function (file) {
shell.sed('-i', 'BUILD_VERSION', 'v0.1.2', file);
shell.sed('-i', /^.*REMOVE_THIS_LINE.*$/, '', file);
shell.sed('-i', /.*REPLACE_LINE_WITH_MACRO.*\n/, shell.cat('macro.js'), file);
});
shell.cd('..');
// Run external tool synchronously
if (shell.exec('git commit -am "Auto-commit"').code !== 0) {
shell.echo('Error: Git commit failed');
shell.exit(1);
}
Also, you can use from the command line:
$ shx mkdir -p foo
$ shx touch foo/bar.txt
$ shx rm -rf foo
Open your project in XCode
you will see the sidebar now focus on the attached image.
Search your specific SDK or any dublicate file where you facing an issue.
You will see that you have added any file twice.
just remove that file and your issue will be resolved.
Note: you have to remove the file from that place where you add it wrongly.
Note: Just remove FBSDKCoreKit from Frameworks
Good Luck
you can test a color by writing the CSS inline like <div style="color:red";>...</div>
1 You can use a drawable
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/menu_item1"
android:icon="@drawable/my_item_drawable"
android:title="@string/menu_item1"
android:showAsAction="ifRoom" />
</menu>
2 Create a style for the action bar and use a custom background:
<resources>
<!-- the theme applied to the application or activity -->
<style name="CustomActivityTheme" parent="@android:style/Theme.Holo">
<item name="android:actionBarStyle">@style/MyActionBar</item>
<!-- other activity and action bar styles here -->
</style>
<!-- style for the action bar backgrounds -->
<style name="MyActionBar" parent="@android:style/Widget.Holo.ActionBar">
<item name="android:background">@drawable/background</item>
<item name="android:backgroundStacked">@drawable/background</item>
<item name="android:backgroundSplit">@drawable/split_background</item>
</style>
</resources>
3 Style again android:actionBarDivider
The android documentation is very usefull for that.
if you want to make use of lamdas and make it a bit easier to read
List<Map<String,String>> results;
Comparator<Map<String,String>> sortByName = Comparator.comparing(x -> x.get("Name"));
public void doSomething(){
results.sort(sortByName)
}
Just click first on that link and go to HTML page where actual downloads or mirrors are.
Its really misleading to have full link which ends in .tgz when it actually leads to HTML page where real download links are. I had this problem downloading Apache Spark and wget-ing it into Ubuntu.

Difference between “@+id/”
and “@id/”
in Android
The first one is used for to create the ID
of the particular ui component and the another one is used for to refer the particular component
For me for any reason :
rm .git/index.lock
Didn't work, so I just went to the .git file and deleted it manually which worked fantastically.
You are inside a namespace
so you should use \Exception
to specify the global namespace:
try {
$this->buildXMLHeader();
} catch (\Exception $e) {
return $e->getMessage();
}
In your code you've used catch (Exception $e)
so Exception
is being searched in/as:
App\Services\PayUService\Exception
Since there is no Exception
class inside App\Services\PayUService
so it's not being triggered. Alternatively, you can use a use
statement at the top of your class like use Exception;
and then you can use catch (Exception $e)
.
My first question is which version of SQL Server are you using (i.e 2005, 2008, 2008 R2, 2012)?
Assuming you are using 2008 or later SQL uses scope for variable determination. I believe 2005 still had global variables that would use @@variablename instead of @variable name which would define the difference between global and local variables. Starting in 2008 I believe this was changed to a scope defined variable designation structure. For example to create a global variable the @variable has to be defined at the start of a procedure, function, view, etc. In 2008 and later @@defined system variables for system functions I do believe. I could explain further if you explained the version and also where the variable is being defined, and the error that you are getting.
You need to read from req.Body
. The ParseForm
method is reading from the req.Body
and then parsing it in standard HTTP encoded format. What you want is to read the body and parse it in JSON format.
Here's your code updated.
package main
import (
"encoding/json"
"log"
"net/http"
"io/ioutil"
)
type test_struct struct {
Test string
}
func test(rw http.ResponseWriter, req *http.Request) {
body, err := ioutil.ReadAll(req.Body)
if err != nil {
panic(err)
}
log.Println(string(body))
var t test_struct
err = json.Unmarshal(body, &t)
if err != nil {
panic(err)
}
log.Println(t.Test)
}
func main() {
http.HandleFunc("/test", test)
log.Fatal(http.ListenAndServe(":8082", nil))
}
The below is less efficient, but I use this logic. This is valid only if you have two digits after decimal point.
double val;
if (temp.Text.Split('.').Length > 1)
{
val = double.Parse(temp.Text.Split('.')[0]);
if (temp.Text.Split('.')[1].Length == 1)
val += (0.1 * double.Parse(temp.Text.Split('.')[1]));
else
val += (0.01 * double.Parse(temp.Text.Split('.')[1]));
}
else
val = double.Parse(RR(temp.Text));
New-PSDrive -Name HKCR -PSProvider Registry -Root HKEY_CLASSES_ROOT

In Font Awesome 5 it can be done using pure CSS as in some of the above answers with some modifications.
ul {
list-style-type: none;
}
li:before {
position: absolute;
font-family: 'Font Awesome 5 free';
/* Use the Name of the Font Awesome free font, e.g.:
- 'Font Awesome 5 Free' for Regular and Solid symbols;
- 'Font Awesome 5 Brand' for Brands symbols.
- 'Font Awesome 5 Pro' for Regular and Solid symbols (Professional License);
*/
content: "\f1fc"; /* Unicode value of the icon to use: */
font-weight: 900; /* This is important, change the value according to the font family name
used above. See the link below */
color: red;
}
Without the correct font-weight, it will only show a blank square.

in addition to all answers above:
if you want to use a gif for your github repository README.md and don't want to address it from your root directory, it's not enough if you just copy the url of your browser, for example your browser URL is sth like:
https://github.com/ashkan-nasirzadeh/simpleShell/blob/master/README%20assets/shell-gif.gif
but you should open your gif in your github account and right click on it and click copy image address
or sth like that which is sth like this:
https://github.com/ashkan-nasirzadeh/simpleShell/blob/master/README%20assets/shell-gif.gif?raw=true
In Python 3, all strings are sequences of Unicode characters. There is a bytes
type that holds raw bytes.
In Python 2, a string may be of type str
or of type unicode
. You can tell which using code something like this:
def whatisthis(s):
if isinstance(s, str):
print "ordinary string"
elif isinstance(s, unicode):
print "unicode string"
else:
print "not a string"
This does not distinguish "Unicode or ASCII"; it only distinguishes Python types. A Unicode string may consist of purely characters in the ASCII range, and a bytestring may contain ASCII, encoded Unicode, or even non-textual data.

I think that I got a solution for this. You don't have to start monitor but you can use DDMS instead almost like in Eclipse.
Start Android Studio-> pick breakpoint-> Run-> Debug-> Go to %sdk\tools in Terminal window and run ddms.bat to run DDMS without Monitor running (since it won't let you run ADB). You can now start profiling or debug step-by-step.
Hope this helps you.

The thing is that you are using the option -t

Taking the top answer, as well as the suggestions from its comments, and modifying it to use SecureString instead of String, test for all control keys, and not error or write an extra "*" to the screen when the password length is 0, my solution is:
public static SecureString getPasswordFromConsole(String displayMessage) {
SecureString pass = new SecureString();
Console.Write(displayMessage);
ConsoleKeyInfo key;
do {
key = Console.ReadKey(true);
// Backspace Should Not Work
if (!char.IsControl(key.KeyChar)) {
pass.AppendChar(key.KeyChar);
Console.Write("*");
} else {
if (key.Key == ConsoleKey.Backspace && pass.Length > 0) {
pass.RemoveAt(pass.Length - 1);
Console.Write("\b \b");
}
}
}
// Stops Receving Keys Once Enter is Pressed
while (key.Key != ConsoleKey.Enter);
return pass;
}

You can not update identity column.
SQL Server does not allow to update the identity column unlike what you can do with other columns with an update statement.
Although there are some alternatives to achieve a similar kind of requirement.
Use DBCC CHECKIDENT which checks the current identity value for the table and if it's needed, changes the identity value.
DBCC CHECKIDENT('tableName', RESEED, NEW_RESEED_VALUE)
Use IDENTITY_INSERT which allows explicit values to be inserted into the identity column of a table.
SET IDENTITY_INSERT YourTable {ON|OFF}
Example:
-- Set Identity insert on so that value can be inserted into this column
SET IDENTITY_INSERT YourTable ON
GO
-- Insert the record which you want to update with new value in the identity column
INSERT INTO YourTable(IdentityCol, otherCol) VALUES(13,'myValue')
GO
-- Delete the old row of which you have inserted a copy (above) (make sure about FK's)
DELETE FROM YourTable WHERE ID=3
GO
--Now set the idenetity_insert OFF to back to the previous track
SET IDENTITY_INSERT YourTable OFF

From my notes:
Which parses like this:
q=latN+lonW+(label) location of teardrop
t=k keyhole (satelite map)
t=h hybrid
ll=lat,-lon center of map
spn=w.w,h.h span of map, degrees
iwloc has something to do with the info window. hl is obviously language.

rem This is the command line version
cscript "C:\Users\guest\Desktop\123\MyScript.vbs"
OR
rem This is the windowed version
wscript "C:\Users\guest\Desktop\123\MyScript.vbs"
You can also add the option //e:vbscript
to make sure the scripting engine will recognize your script as a vbscript.
Windows/DOS batch files doesn't require escaping \
like *nix.
You can still use "C:\Users\guest\Desktop\123\MyScript.vbs"
, but this requires the user has *.vbs
associated to wscript
.
You need to use the SUBTOTAL function. The SUBTOTAL function ignores rows that have been excluded by a filter.
The formula would look like this:
=SUBTOTAL(9,B1:B20)
The function number 9, tells it to use the SUM function on the data range B1:B20.
If you are 'filtering' by hiding rows, the function number should be updated to 109.
=SUBTOTAL(109,B1:B20)
The function number 109 is for the SUM function as well, but hidden rows are ignored.
How about this:
var imageUrl = 'https://cdn.sstatic.net/Sites/stackoverflow/img/sprites.svg';
var blob = null;
var xhr = new XMLHttpRequest();
xhr.open('GET', imageUrl, true);
xhr.responseType = 'blob';
xhr.onload = function()
{
blob = xhr.response;
console.log(blob, blob.size);
}
xhr.send();

I think you missed a equal sign at:
Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + "" + l, null, null, null, null);
Change to:
Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + " = " + l, null, null, null, null);
Array.fill
Consider using fill
:
Array(9).fill().map(()=>Array(9).fill())
The idea here is that fill()
will fill out the items with undefined
, which is enough to get map
to work on them.
You could also fill directly:
Array(9).fill(Array(9))
Alternatives to Array(9).fill()
include
Array(...Array(9))
[].push(...Array(9))
[].concat(Array(9))
Array.from(Array(9))
We can rewrite the solution a bit more semantically as:
function array9() { return Array(9).fill(); }
array9().map(array9)
or
function array(n) { return Array(n).fill(); }
array(9).map(() => array(9))
Array.from
provides us with an optional second mapping argument, so we have the alternative of writing
Array.from(Array(9), () => Array.from(Array(9));
or, if you prefer
function array9(map) { return Array.from(Array(9), map); }
array9(array9);
For verbose description and examples, see Mozilla's Docs on Array.prototype.fill()
here.
and for Array.from()
, here.
Note that neither Array.prototype.fill()
nor Array.from()
has support in Internet Explorer. A polyfill for IE is available at the above MDN links.
partition(Array(81), 9)
if you have a partition
utility handy. Here's a quick recursive one:
function partition(a, n) {
return a.length ? [a.splice(0, n)].concat(partition(a, n)) : [];
}
We can loop a bit more efficiently with
var a = [], b;
while (a.push(b = []) < 9) while (b.push(null) < 9);
Taking advantage of the fact that push
returns the new array length.
Try:
String path1 = "path1";
String path2 = "path2";
String joinedPath = new File(path1, path2).toString();
Just call fig.tight_layout()
as you normally would. (pyplot
is just a convenience wrapper. In most cases, you only use it to quickly generate figure and axes objects and then call their methods directly.)
There shouldn't be a difference between the QtAgg
backend and the default backend (or if there is, it's a bug).
E.g.
import matplotlib.pyplot as plt
#-- In your case, you'd do something more like:
# from matplotlib.figure import Figure
# fig = Figure()
#-- ...but we want to use it interactive for a quick example, so
#-- we'll do it this way
fig, axes = plt.subplots(nrows=4, ncols=4)
for i, ax in enumerate(axes.flat, start=1):
ax.set_title('Test Axes {}'.format(i))
ax.set_xlabel('X axis')
ax.set_ylabel('Y axis')
plt.show()
import matplotlib.pyplot as plt
fig, axes = plt.subplots(nrows=4, ncols=4)
for i, ax in enumerate(axes.flat, start=1):
ax.set_title('Test Axes {}'.format(i))
ax.set_xlabel('X axis')
ax.set_ylabel('Y axis')
fig.tight_layout()
plt.show()
Have you tried using str.splitlines()
method?:
From the docs:
Return a list of the lines in the string, breaking at line boundaries. Line breaks are not included in the resulting list unless
keepends
is given and true.
For example:
>>> 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines()
['Line 1', '', 'Line 3', 'Line 4']
>>> 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines(True)
['Line 1\n', '\n', 'Line 3\r', 'Line 4\r\n']
This method uses the universal newlines approach to splitting lines.
The main difference between Python 2.X
and Python 3.X
is that the former uses the universal newlines approach to splitting lines, so "\r"
, "\n"
, and "\r\n"
are considered line boundaries for 8-bit strings, while the latter uses a superset of it that also includes:
\v
or \x0b
: Line Tabulation (added in Python 3.2
).\f
or \x0c
: Form Feed (added in Python 3.2
).\x1c
: File Separator.\x1d
: Group Separator.\x1e
: Record Separator.\x85
: Next Line (C1 Control Code).\u2028
: Line Separator.\u2029
: Paragraph Separator.Unlike
str.split()
when a delimiter string sep is given, this method returns an empty list for the empty string, and a terminal line break does not result in an extra line:
>>> ''.splitlines()
[]
>>> 'Line 1\n'.splitlines()
['Line 1']
While str.split('\n')
returns:
>>> ''.split('\n')
['']
>>> 'Line 1\n'.split('\n')
['Line 1', '']
If you also need to remove additional leading or trailing whitespace, like spaces, that are ignored by str.splitlines()
, you could use str.splitlines()
together with str.strip()
:
>>> [str.strip() for str in 'Line 1 \n \nLine 3 \rLine 4 \r\n'.splitlines()]
['Line 1', '', 'Line 3', 'Line 4']
Lastly, if you want to filter out the empty strings from the resulting list, you could use filter()
:
>>> # Python 2.X:
>>> filter(bool, 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines())
['Line 1', 'Line 3', 'Line 4']
>>> # Python 3.X:
>>> list(filter(bool, 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines()))
['Line 1', 'Line 3', 'Line 4']
As the error you posted indicates and Burhan suggested, the problem is from the print. There's a related question about that could be useful to you: UnicodeEncodeError: 'charmap' codec can't encode - character maps to <undefined>, print function

Also, I found this thread researching powershell. Here is an example command that runs the utility to get the true memory available on the GPU to get you started.
# get gpu metrics
$cmd = "& 'C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi' --query-gpu=name,utilization.memory,driver_version --format=csv"
$gpuinfo = invoke-expression $cmd | ConvertFrom-CSV
$gpuname = $gpuinfo.name
$gpuutil = $gpuinfo.'utilization.memory [%]'.Split(' ')[0]
$gpuDriver = $gpuinfo.driver_version
**var spge = '';**
alert(spge);
That really works.
Simple,
Easy to understand,
Single method to set and update plugin which worked for me.
$(".datepicker").datepicker("update", new Date());
Other ways to update
$('.datepicker').data({date: '2015-01-01'});
$('.datepicker').datepicker('update');
Dont forget to call update
manually.
If you want to extract from a
tag then
$('.dep_buttons').text().substr(0,25)
With the mouseover event,
$(this).text($(this).text().substr(0, 25));
The above will extract the text of a tag, then extract again assign it back.
My way of doing it is:
right('0'+right(datepart(month,[StartDate]),2),2)
The reason for the internal 'right' function is to prevent SQL from doing it as math add - which will leave us with one digit again.
You could use the timeout
setting in the ajax options like this:
$.ajax({
url: "test.html",
timeout: 3000,
error: function(){
//do something
},
success: function(){
//do something
}
});
Read all about the ajax options here: http://api.jquery.com/jQuery.ajax/
Remember that when a timeout occurs, the error
handler is triggered and not the success
handler :)
I am starting out with python and I use id when I use the interactive shell to see whether my variables are assigned to the same thing or if they just look the same.
Every value is an id, which is a unique number related to where it is stored in the memory of the computer.
I have no experience with Git, but I have with Mercurial which is also a distributed VCS. It depends on the project really, but in our case a distributed VCS suited the project as basically eliminated frequent broken builds.
I think it depends on the project really, as some are better suited towards a client-server VCS, and others towads a distributed one.
For those having a hard time implementing the accepted answer (which requires org.apache.http.entity.mime.MultipartEntity) you may be using org.apache.httpcomponents 4.2.* In this case, you have to explicitly install httpmime dependency, in my case:
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpmime</artifactId>
<version>4.2.5</version>
</dependency>
We can write a bash script like below
truncate_tables_in_mysql() {
type mysql >/dev/null 2>&1 && echo "MySQL present." || sudo apt-get install -y mysql-client
tables=$(mysql -h 127.0.0.1 -P $MYSQL_PORT -u $MYSQL_USER -p$MYSQL_PASSWORD -e "USE $BACKEND_DATABASE;
SHOW TABLES;")
tables_list=($tables)
query_string="USE $BACKEND_DATABASE; SET FOREIGN_KEY_CHECKS = 0;"
for table in "${tables_list[@]:1}"
do
query_string="$query_string TRUNCATE TABLE \`$table\`; "
done
query_string="$query_string SET FOREIGN_KEY_CHECKS = 1;"
mysql -h 127.0.0.1 -P $MYSQL_PORT -u $MYSQL_USER -p$MYSQL_PASSWORD -e "$query_string"
}
You can replace env variables with your MySQL details. Using one command you can truncate all the tables in a DB.
error find by itself after a RND :
1) my error code :
return res.sendStatus(200).json({ data: result });
2) my success code
return res.status(200).json({ data: result });
the difference is that i used sendStatus() instead of status().
XMLHttpRequest
is a standard object in the JavaScript Object model.
According to Wikipedia, XMLHttpRequest
first appeared in Internet Explorer 5 as an ActiveX object, but has since been made into a standard and has been included for use in JavaScript in the Mozilla family since 1.0, Apple Safari 1.2, Opera 7.60-p1, and IE 7.0.
The open()
method on the object takes the HTTP Method as an argument - and is specified as taking any valid HTTP method (see the item number 5 of the link) - including GET
, POST
, HEAD
, PUT
and DELETE
, as specified by RFC 2616.
(class/ID):after {
content:none;
}
Always works for me class or ID can be for a div or even body causing the white space.
I'm getting an index out of range error with the accepted answer solution. Reason: When range start, it is not iterate value one by one, it is iterate by index. If you modified a slice while it is in range, it will induce some problem.
Old Answer:
chars := []string{"a", "a", "b"}
for i, v := range chars {
fmt.Printf("%+v, %d, %s\n", chars, i, v)
if v == "a" {
chars = append(chars[:i], chars[i+1:]...)
}
}
fmt.Printf("%+v", chars)
Expected :
[a a b], 0, a
[a b], 0, a
[b], 0, b
Result: [b]
Actual:
// Autual
[a a b], 0, a
[a b], 1, b
[a b], 2, b
Result: [a b]
Correct Way (Solution):
chars := []string{"a", "a", "b"}
for i := 0; i < len(chars); i++ {
if chars[i] == "a" {
chars = append(chars[:i], chars[i+1:]...)
i-- // form the remove item index to start iterate next item
}
}
fmt.Printf("%+v", chars)

Can you change the if condition to this:
if (!is.na(comments[l])) print(comments[l]);
You can only check for NA values with is.na().
It’s about time someone provides the modern answer. The modern solution uses java.time, the modern Java date and time API. The classes SimpleDateFormat
and Date
used in the question and in a couple of the other answers are poorly designed and long outdated, the former in particular notoriously troublesome. TimeZone
is poorly designed to. I recommend you avoid those.
ZoneId utc = ZoneId.of("Etc/UTC");
DateTimeFormatter targetFormatter = DateTimeFormatter.ofPattern(
"MM/dd/yyyy hh:mm:ss a zzz", Locale.ENGLISH);
String itsAlarmDttm = "2013-10-22T01:37:56";
ZonedDateTime utcDateTime = LocalDateTime.parse(itsAlarmDttm)
.atZone(ZoneId.systemDefault())
.withZoneSameInstant(utc);
String formatterUtcDateTime = utcDateTime.format(targetFormatter);
System.out.println(formatterUtcDateTime);
When running in my time zone, Europe/Copenhagen, the output is:
10/21/2013 11:37:56 PM UTC
I have assumed that the string you got was in the default time zone of your JVM, a fragile assumption since that default setting can be changed at any time from another part of your program or another programming running in the same JVM. If you can, instead specify time zone explicitly, for example ZoneId.of("Europe/Podgorica")
or ZoneId.of("Asia/Kolkata")
.
I am exploiting the fact that you string is in ISO 8601 format, the format the the modern classes parse as their default, that is, without any explicit formatter.
I am using a ZonedDateTime
for the result date-time because it allows us to format it with UTC
in the formatted string to eliminate any and all doubt. For other purposes one would typically have wanted an OffsetDateTime
or an Instant
instead.
I had this same problem and it seemed to be related to using the same database connection for concurrent tasks. There might be some alternative solutions (maybe better), but I solved it by setting MaxConcurrentExecutables
to 1.
I haven't tried it but if you put a div in your table cell set so that it will have scrollbars if needed, then you could insert in there, with a fixed height on the div and it should keep your table row to a fixed height.

Using emplace_back
function is way better than any other method since it creates an object in-place of type T
where vector<T>
, whereas push_back
expects an actual value from you.
vector<pair<string,double>> revenue;
// make_pair function constructs a pair objects which is expected by push_back
revenue.push_back(make_pair("cash", 12.32));
// emplace_back passes the arguments to the constructor
// function and gets the constructed object to the referenced space
revenue.emplace_back("cash", 12.32);
Go with the first and use single quotes!
The only situations when you should use double quotes, is when you need \r
, \n
, \t
!
The overhead is just not worth it to use it in any other case.
You should also check PHP variable concatenation, phpbench.com for some benchmarks on different methods of doing things.
For Mac Users
I am using Mac and I was facing same problem while I was trying to push a project from Android Studio. The reason for that other user had previously logged into Github and his credentials were saved in Keychain Access.
You need to remove those credentials from Keychain Access and then try to push.
Hope it help to Mac users.
How about just using:
result = [VLOOKUP(DATA!AN2, DATA!AA9:AF20, 5, FALSE)]
Note the [ and ].
My app is compiled on API LEVEL 29, but debugging on real device on API LEVEL 28.I got the warning source code does not match the bytecode
in AndroidStudio.I fixed it thought these steps:
Go to Preferences>Instant Run: uncheck the instant run
Go to Build>Clean Build
Re-RUN the app
Now, the debug runs normal.
As others suggested, NSMutableArray has methods to do so but sometimes you are forced to use NSArray, I'd use:
NSArray* newArray = [oldArray subarrayWithRange:NSMakeRange(1, [oldArray count] - 1)];
This way, the oldArray stays as it was but a newArray will be created with the first item removed.
In C++20 this is possible using the following syntax:
auto lambda = []<typename T>(T t){
// do something
};
How easy :)
date("F j, Y", strtotime( '-1 days' ) );
Example:
echo date("Y-m-j H:i:s", strtotime( '-1 days' ) ); // 2018-07-18 07:02:43
Output:
2018-07-17 07:02:43

You should not pass the call function hi() to the loop() function, This will give the result.
def hi():
print('hi')
def loop(f, n): #f repeats n times
if n<=0:
return
else:
f()
loop(f, n-1)
loop(hi, 5) # Do not use hi() function inside loop() function

When you run a shell script, it's done in a sub-shell so it cannot affect the parent shell's environment. You want to source the script by doing:
. ./setfoo.sh
This executes it in the context of the current shell, not as a sub shell.
From the bash man page:
. filename [arguments]
source filename [arguments]Read and execute commands from filename in the current shell environment and return the exit status of the last command executed from filename.
If filename does not contain a slash, file names in PATH are used to find the directory containing filename.
The file searched for in PATH need not be executable. When bash is not in POSIX mode, the current directory is searched if no file is found in PATH.
If the sourcepath option to the shopt builtin command is turned off, the PATH is not searched.
If any arguments are supplied, they become the positional parameters when filename is executed.
Otherwise the positional parameters are unchanged. The return status is the status of the last command exited within the script (0 if no commands are executed), and false if filename is not found or cannot be read.
TL;DR ...and late to the party, but that short explanation might help future googlers..
In general that error message means that the replacement doesn't fit into the corresponding column of the dataframe.
A minimal example:
df <- data.frame(a = 1:2); df$a <- 1:3
throws the error
Error in
$<-.data.frame
(*tmp*
, a, value = 1:3) : replacement has 3 rows, data has 2
which is clear, because the vector a
of df
has 2 entries (rows) whilst the vector we try to replace it has 3 entries (rows).
Instead of declaring a function in your scope, as suggested by Alex, you can convert it to a simple filter :
angular.module('myApp')
.filter('to_trusted', ['$sce', function($sce){
return function(text) {
return $sce.trustAsHtml(text);
};
}]);
Then you can use it like this :
<div ng-bind-html="preview_data.preview.embed.html | to_trusted"></div>
And here is a working example : http://jsfiddle.net/leeroy/6j4Lg/1/

ffmpeg logs to stderr, and can log to a file with a different log-level from stderr. The -report
command-line option doesn't give you control of the log file name or the log level, so setting the environment variable is preferable.
(-v
is a synonym for -loglevel
. Run ffmpeg -v help
to see the levels. Run ffmpeg -h full | less
to see EVERYTHING. Or consult the online docs, or their wiki pages like the h.264 encode guide).
#!/bin/bash
of=out.mkv
FFREPORT="level=32:file=$of.log" ffmpeg -v verbose -i src.mp4 -c:a copy -preset slower -c:v libx264 -crf 21 "$of"
That will trancode src.mp4
with x264, and set the log level for stderr to "verbose", and the log level for out.mkv.log
to "status".
(AV_LOG_WARNING=24
, AV_LOG_INFO=32
, AV_LOG_VERBOSE=40
, etc.). Support for this was added 2 years ago, so you need a non-ancient version of ffmpeg. (Always a good idea anyway, for security / bugfixes and speedups)
A few codecs, like -c:v libx265
, write directly to stderr instead of using ffmpeg's logging infrastructure. So their log messages don't end up in the report file. I assume this is a bug / TODO-list item.
To log stderr, while still seeing it in a terminal, you can use tee(1)
.
If you use a log level that includes status line updates (the default -v info
, or higher), they will be included in the log file, separated with ^M
(carriage return aka \r
). There's no log level that includes encoder stats (like SSIM) but not status-line updates, so the best option is probably to filter that stream.
If don't want to filter (e.g. so the fps / bitrate at each status-update interval is there in the file), you can use less -r
to pass them through directly to your terminal so you can view the files cleanly. If you have .enc
logs from several encodes that you want to flip through, less -r ++G *.enc
works great. (++G means start at the end of the file, for all files). With single-key key bindings like .
and ,
for next file and previous file, you can flip through some log files very nicely. (the default bindings are :n
and :p
).
If you do want to filter, sed 's/.*\r//'
works perfectly for ffmpeg output. (In the general case, you need something like vt100.py
, but not for just carriage returns). There are (at least) two ways to do this with tee + sed: tee
to /dev/tty and pipe tee's output into sed, or use a process substitution to tee into a pipe to sed.
# pass stdout and stderr through to the terminal,
## and log a filtered version to a file (with only the last status-line update).
of="$1-x265.mkv"
ffmpeg -v info -i "$1" -c:a copy -c:v libx265 ... "$of" |& # pipe stdout and stderr
tee /dev/tty | sed 's/.*\r//' >> "$of.enc"
## or with process substitution where tee's arg will be something like /dev/fd/123
ffmpeg -v info -i "$1" -c:a copy -c:v libx265 ... "$of" |&
tee >(sed 's/.*\r//' >> "$of.enc")
For testing a few different encode parameters, you can make a function like this one that I used recently to test some stuff. I had it all on one line so I could easily up-arrow and edit it, but I'll un-obfuscate it here. (That's why there are ;
s at the end of each line)
ffenc-testclip(){
# v should be set by the caller, to a vertical resolution. We scale to WxH, where W is a multiple of 8 (-vf scale=-8:$v)

[email protected].${v}p.x265$pre.mkv;
[[ -e "$of.enc" ]]&&echo "$of.enc exists"&&return; # early-out if the file exists
# encode 25 seconds starting at 21m15s (or the keyframe before that)

}
# and use it with nested loops like this.
for pre in fast slow; do for v in 360 480 648 792;do ffenc-testclip ;done;done
less -r ++G *.enc # -r is useful if you didn't use sed
Note that it tests for existence of the output video file to avoid spewing extra garbage into the log file if it already exists. Even so, I used and append (>>
) redirect.
It would be "cleaner" to write a shell function that took args instead of looking at shell variables, but this was convenient and easy to write for my own use. That's also why I saved space by not properly quoting all my variable expansions. ($v
instead of "$v"
)
I fixed the issue without changing the python path as that did not seem like the right solution for me. The following solution worked for me, hopefully it works for you as well :))
Activate your virtualenv (using source activate / activate.bat / activate.ps1 if using power shell)
C:\Users\<myUserName>\Videos\myFolder>django-project\Scripts\activate.bat
(django-project) C:\Users\<myUserName>\Videos\myFolder>
Navigate to your project directory and open vscode there.
(django-project) C:\Users\prash\Videos\myFolder\projects>code .
in VS Code, goto File --> Preferences --> Settings (dont worry you dont need to open the json file)
In the setting search bar search for virtual / venv and hit enter. You should find the below in the search bar:
Python: Venv Folders Folders in your home directory to look into for virtual environments (supports pyenv, direnv and virtualenvwrapper by default).
Add item, and then enter the path of the scripts of your virtuanenv which has the activate file in it. For example in my system, it is:
C:\Users\<myUserName>\Videos\myFolder\django-project\Scripts\
Save it and restart VS Code.
To restart, open cmd again, navigate to your project path and open vs code. (Note that your venv should be activated in cmd before you open vs code from cmd)
Command to open vs code from cmd:

For category relations insertion I came across the same problem and had no idea, except that in my eloquent model I used Self() to have an instance of the same class in foreach to record multiple saves and grabing ids.
foreach($arCategories as $v)
{
if($v>0){
$obj = new Self(); // this is to have new instance of own
$obj->page_id = $page_id;
$obj->category_id = $v;
$obj->save();
}
}
without "$obj = new Self()" it only saves single record (when $obj was $this)
Try this:

But are you sure you are not compressing some .exe file or something? Maybe the problem is not with te compression, but with the files you are compressing?

What the error is telling, is that you can't convert an entire list into an integer. You could get an index from the list and convert that into an integer:
x = ["0", "1", "2"]
y = int(x[0]) #accessing the zeroth element
If you're trying to convert a whole list into an integer, you are going to have to convert the list into a string first:
x = ["0", "1", "2"]
y = ''.join(x) # converting list into string
z = int(y)
If your list elements are not strings, you'll have to convert them to strings before using str.join
:
x = [0, 1, 2]
y = ''.join(map(str, x))
z = int(y)
Also, as stated above, make sure that you're not returning a nested list.
There are a couple of potential problems with this approach, though in a lot of circumstances (such as your example) it will work well.
In particular you should be careful when dealing with anything that deals with the GUI
that requires a Context
. For example, if you pass the application Context into the LayoutInflater
you will get an Exception. Generally speaking, your approach is excellent: it's good practice to use an Activity's
Context
within that Activity
, and the Application Context
when passing a context beyond the scope of an Activity
to avoid memory leaks.
Also, as an alternative to your pattern you can use the shortcut of calling getApplicationContext()
on a Context
object (such as an Activity) to get the Application Context.
System.exit()
is usually not the best way, but it depends on your application.
The usual way of ending an application is by exiting the main()
method. This does not work when there are other non-deamon threads running, as is usual for applications with a graphical user interface (AWT, Swing etc.). For these applications, you either find a way to end the GUI event loop (don't know if that is possible with the AWT or Swing), or invoke System.exit()
.
You can achieve with following way
this.projectService.create(project)
.subscribe(
result => {
console.log(result);
},
error => {
console.log(error);
this.errors = error
}
);
}
if (!this.errors) {
//route to new page
}
Perhaps the easiest one compare to several others.

It matches the following:
(555) 444-6789
555-444-6789
555.444.6789
555 444 6789
Rule of thumb: Use -a
and -o
inside square brackets, &&
and ||
outside.
It's important to understand the difference between shell syntax and the syntax of the [
command.
&&
and ||
are shell operators. They are used to combine the results of two commands. Because they are shell syntax, they have special syntactical significance and cannot be used as arguments to commands.
[
is not special syntax. It's actually a command with the name [
, also known as test
. Since [
is just a regular command, it uses -a
and -o
for its and and or operators. It can't use &&
and ||
because those are shell syntax that commands don't get to see.
But wait! Bash has a fancier test syntax in the form of [[ ]]
. If you use double square brackets, you get access to things like regexes and wildcards. You can also use shell operators like &&
, ||
, <
, and >
freely inside the brackets because, unlike [
, the double bracketed form is special shell syntax. Bash parses [[
itself so you can write things like [[ $foo == 5 && $bar == 6 ]]
.
You can take advantage of the fact that shell command substitutions remove trailing newline characters:
Simple form that works in bash, ksh, zsh:
printf %s "$(< in.txt)" > out.txt
Portable (POSIX-compliant) alternative (slightly less efficient):
printf %s "$(cat in.txt)" > out.txt
Note:
in.txt
ends with multiple newline characters, the command substitution removes all of them.Thanks, Sparhawk (It doesn't remove whitespace characters other than trailing newlines.)printf %s
ensures that no newline is appended to the output (it is the POSIX-compliant alternative to the nonstandard echo -n
; see http://pubs.opengroup.org/onlinepubs/009696799/utilities/echo.html and https://unix.stackexchange.com/a/65819)A guide to the other answers:
If Perl is available, go for the accepted answer - it is simple and memory-efficient (doesn't read the whole input file at once).
Otherwise, consider ghostdog74's Awk answer - it's obscure, but also memory-efficient; a more readable equivalent (POSIX-compliant) is:
awk 'NR > 1 { print prev } { prev=$0 } END { ORS=""; print }' in.txt
Printing is delayed by one line so that the final line can be handled in the END
block, where it is printed without a trailing \n
due to setting the output-record separator (OFS
) to an empty string.
If you want a verbose, but fast and robust solution that truly edits in-place (as opposed to creating a temp. file that then replaces the original), consider jrockway's Perl script.
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()
In order to make numpy display float arrays in an arbitrary format, you can define a custom function that takes a float value as its input and returns a formatted string:
In [1]: float_formatter = "{:.2f}".format
The f
here means fixed-point format (not 'scientific'), and the .2
means two decimal places (you can read more about string formatting here).
Let's test it out with a float value:
In [2]: float_formatter(1.234567E3)
Out[2]: '1234.57'
To make numpy print all float arrays this way, you can pass the formatter=
argument to np.set_printoptions
:
In [3]: np.set_printoptions(formatter={'float_kind':float_formatter})
Now numpy will print all float arrays this way:
In [4]: np.random.randn(5) * 10
Out[4]: array([5.25, 3.91, 0.04, -1.53, 6.68]
Note that this only affects numpy arrays, not scalars:
In [5]: np.pi
Out[5]: 3.141592653589793
It also won't affect non-floats, complex floats etc - you will need to define separate formatters for other scalar types.
You should also be aware that this only affects how numpy displays float values - the actual values that will be used in computations will retain their original precision.
For example:
In [6]: a = np.array([1E-9])
In [7]: a
Out[7]: array([0.00])
In [8]: a == 0
Out[8]: array([False], dtype=bool)
numpy prints a
as if it were equal to 0
, but it is not - it still equals 1E-9
.
If you actually want to round the values in your array in a way that affects how they will be used in calculations, you should use np.round
, as others have already pointed out.
Don't reinvent the wheel! Import this amazing library:
https://github.com/giggsey/libphonenumber-for-php
$defaultCountry = 'SE'; // Based on the country of the user
$phoneUtil = PhoneNumberUtil::getInstance();
$swissNumberProto = $phoneUtil->parse($phoneNumber, $defaultCountry);
return $phoneUtil->format($swissNumberProto, PhoneNumberFormat::INTERNATIONAL);
It is based on Google's library for parsing, formatting, and validating international phone numbers: https://github.com/google/libphonenumber
You don't need to apply to_date()
to sysdate
. It is already there:
select 1
from dual
WHERE sysdate BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND TO_DATE('20/06/2014', 'DD/MM/YYYY');
If you are concerned about the time component on the date, then use trunc()
:
select 1
from dual
WHERE trunc(sysdate) BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND
TO_DATE('20/06/2014', 'DD/MM/YYYY');
So I used to use a for loop for iterating through the dictionary as well, but one thing I've found that works much faster is to convert to a panel and then to a dataframe. Say you have a dictionary d
import pandas as pd
d
{'RAY Index': {datetime.date(2014, 11, 3): {'PX_LAST': 1199.46,
'PX_OPEN': 1200.14},
datetime.date(2014, 11, 4): {'PX_LAST': 1195.323, 'PX_OPEN': 1197.69},
datetime.date(2014, 11, 5): {'PX_LAST': 1200.936, 'PX_OPEN': 1195.32},
datetime.date(2014, 11, 6): {'PX_LAST': 1206.061, 'PX_OPEN': 1200.62}},
'SPX Index': {datetime.date(2014, 11, 3): {'PX_LAST': 2017.81,
'PX_OPEN': 2018.21},
datetime.date(2014, 11, 4): {'PX_LAST': 2012.1, 'PX_OPEN': 2015.81},
datetime.date(2014, 11, 5): {'PX_LAST': 2023.57, 'PX_OPEN': 2015.29},
datetime.date(2014, 11, 6): {'PX_LAST': 2031.21, 'PX_OPEN': 2023.33}}}
The command
pd.Panel(d)
<class 'pandas.core.panel.Panel'>
Dimensions: 2 (items) x 2 (major_axis) x 4 (minor_axis)
Items axis: RAY Index to SPX Index
Major_axis axis: PX_LAST to PX_OPEN
Minor_axis axis: 2014-11-03 to 2014-11-06
where pd.Panel(d)[item] yields a dataframe
pd.Panel(d)['SPX Index']
2014-11-03 2014-11-04 2014-11-05 2014-11-06
PX_LAST 2017.81 2012.10 2023.57 2031.21
PX_OPEN 2018.21 2015.81 2015.29 2023.33
You can then hit the command to_frame() to turn it into a dataframe. I use reset_index as well to turn the major and minor axis into columns rather than have them as indices.
pd.Panel(d).to_frame().reset_index()
major minor RAY Index SPX Index
PX_LAST 2014-11-03 1199.460 2017.81
PX_LAST 2014-11-04 1195.323 2012.10
PX_LAST 2014-11-05 1200.936 2023.57
PX_LAST 2014-11-06 1206.061 2031.21
PX_OPEN 2014-11-03 1200.140 2018.21
PX_OPEN 2014-11-04 1197.690 2015.81
PX_OPEN 2014-11-05 1195.320 2015.29
PX_OPEN 2014-11-06 1200.620 2023.33
Finally, if you don't like the way the frame looks you can use the transpose function of panel to change the appearance before calling to_frame() see documentation here http://pandas.pydata.org/pandas-docs/dev/generated/pandas.Panel.transpose.html
Just as an example
pd.Panel(d).transpose(2,0,1).to_frame().reset_index()
major minor 2014-11-03 2014-11-04 2014-11-05 2014-11-06
RAY Index PX_LAST 1199.46 1195.323 1200.936 1206.061
RAY Index PX_OPEN 1200.14 1197.690 1195.320 1200.620
SPX Index PX_LAST 2017.81 2012.100 2023.570 2031.210
SPX Index PX_OPEN 2018.21 2015.810 2015.290 2023.330
Hope this helps.
Please keep an eye on the mailing list for problems/solutions discussed by community members. https://groups.google.com/forum/?fromgroups#!forum/angular . It's been really useful to me.
for python 3.4.2 I found the following will work:
import urllib.request
import json
body = {'ids': [12, 14, 50]}
myurl = "http://www.testmycode.com"
req = urllib.request.Request(myurl)
req.add_header('Content-Type', 'application/json; charset=utf-8')
jsondata = json.dumps(body)
jsondataasbytes = jsondata.encode('utf-8') # needs to be bytes
req.add_header('Content-Length', len(jsondataasbytes))
response = urllib.request.urlopen(req, jsondataasbytes)
Use JSON.stringify() to wrap your json
var parameter = JSON.stringify({type:"user", username:user_email, password:user_password});
$http.post(url, parameter).
success(function(data, status, headers, config) {
// this callback will be called asynchronously
// when the response is available
console.log(data);
}).
error(function(data, status, headers, config) {
// called asynchronously if an error occurs
// or server returns response with an error status.
});
This helped me.
#outer {
position:relative;
}
#inner {
position:absolute;
top:0;
left:0px;

Change right: and left: to set preferable #inner width.
For SQl Server the most efficient way is:
with
ids as ( --condition for split table into groups
select i from (values (9),(12),(17),(18),(19),(20),(22),(21),(23),(10)) as v(i)
)
,src as (
select * from yourTable where <condition> --use this as filter for other conditions
)
,joined as (
select tops.* from ids
cross apply --it`s like for each rows
(
select top(1) *
from src
where CommodityId = ids.i
) as tops
)
select * from joined
and don't forget to create clustered index for used columns
var_dump()
will show you the type of the thing as well as what's in it.
So you'll get => (string)"var"
Example is here.
print_r()
will just output the content.
Would output => "var"
Example is here.
You may want to use time proved xPDF and derived tools to extract text instead as pyPDF2 seems to have various issues with the text extraction still.
The long answer is that there are lot of variations how a text is encoded inside PDF and that it may require to decoded PDF string itself, then may need to map with CMAP, then may need to analyze distance between words and letters etc.
In case the PDF is damaged (i.e. displaying the correct text but when copying it gives garbage) and you really need to extract text, then you may want to consider converting PDF into image (using ImageMagik) and then use Tesseract to get text from image using OCR.
Human readable: (eg. can be log to text file..)
print_r( $arr_name , TRUE);
In asp.net for giving new line character in string you should use <br>
.
For window base application Environment.NewLine
will work fine.
you need to use os.system
module to execute shell command
import os
os.system('command')
if you want to save the output for later use, you need to use subprocess
module
import subprocess
child = subprocess.Popen('command',stdout=subprocess.PIPE,shell=True)
output = child.communicate()[0]
Here's the list of all Win32 error codes. You can use this page to lookup the error code mentioned in IIS logs:

You can also use command line utility net
to find information about a Win32 error code. The syntax would be:

If you are using Laravel 5.6, it comes with Bootstrap 4. All you need to is:
npm install and npm install open-iconic --save
At /resources/assets/sass/app.scss
change the line of of Google font import on line 2 to
@import '~open-iconic/font/css/open-iconic-bootstrap';
All you need to do now is
npm run watch
and include
<link rel="stylesheet" href="{{asset('css/app.css')}}">
on top of master blade file and <script src="{{asset('js/app.js')}}"></script>
before closing body tag. You will get Bootstrap 4 and icon.
Usage is <span class="oi oi-cog"></span>
Refer here for icon details: Open Iconic: Recommended by Bootstrap 4
If on other project than Laravel, you can just do import @import 'node_modules/open-iconic/font/css/open-iconic-bootstrap-min.css';
in your style file.
Hope this helps. Happy trying.
this is what it worked for me I'm using html2pdf from an Angular2 app, so I made a reference to this function in the controller
var html2pdf = (function(html2canvas, jsPDF) {
declared in html2pdf.js.
So I added just after the import declarations in my angular-controller this declaration:
declare function html2pdf(html2canvas, jsPDF): any;
then, from a method of my angular controller I'm calling this function:
generate_pdf(){
this.someService.loadContent().subscribe(
pdfContent => {
html2pdf(pdfContent, {
margin: 1,
filename: 'myfile.pdf',
image: { type: 'jpeg', quality: 0.98 },
html2canvas: { dpi: 192, letterRendering: true },
jsPDF: { unit: 'in', format: 'A4', orientation: 'portrait' }
});
}
);
}
Hope it helps
Here are the steps that worked for me after logging into the box:
Locate MySQL configuration file:
$ mysql --help | grep -A 1 "Default options"
Default options are read from the following files in the given order: /etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf
On Ubuntu 16, the path is typically /etc/mysql/mysql.conf.d/mysqld.cnf
Change configuration file for bind-address:
If it exists, change the value as follows. If it doesn't exist, add it anywhere in the [mysqld] section.
bind-address = 0.0.0.0
Save your changes to the configuration file and restart the MySQL service.
service mysql restart
Create / Grant access to database user:
Connect to the MySQL database as the root user and run the following SQL commands:
mysql> CREATE USER 'username'@'%' IDENTIFIED BY 'password';
mysql> GRANT ALL PRIVILEGES ON mydb.* TO 'username'@'%';
no... Once u have executed the statement anotherList.addAll(list) and after that if u change some list data it does not carry to another list
Save the array in a local variable and use the array's length
field to find its length. Subtract one to account for it being 0-based:
String[] bits = one.split("-");
String lastOne = bits[bits.length-1];
Caveat emptor: if the original string is composed of only the separator, for example "-"
or "---"
, bits.length
will be 0 and this will throw an ArrayIndexOutOfBoundsException. Example: https://onlinegdb.com/r1M-TJkZ8
bcrypt
is a hashing algorithm which is scalable with hardware (via a configurable number of rounds). Its slowness and multiple rounds ensures that an attacker must deploy massive funds and hardware to be able to crack your passwords. Add to that per-password salts (bcrypt
REQUIRES salts) and you can be sure that an attack is virtually unfeasible without either ludicrous amount of funds or hardware.
bcrypt
uses the Eksblowfish algorithm to hash passwords. While the encryption phase of Eksblowfish and Blowfish are exactly the same, the key schedule phase of Eksblowfish ensures that any subsequent state depends on both salt and key (user password), and no state can be precomputed without the knowledge of both. Because of this key difference, bcrypt
is a one-way hashing algorithm. You cannot retrieve the plain text password without already knowing the salt, rounds and key (password). [Source]
Password hashing functions have now been built directly into PHP >= 5.5. You may now use password_hash()
to create a bcrypt
hash of any password:
<?php
// Usage 1:
echo password_hash('rasmuslerdorf', PASSWORD_DEFAULT)."\n";
// $2y$10$xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
// For example:
// $2y$10$.vGA1O9wmRjrwAVXD98HNOgsNpDczlqm3Jq7KnEd1rVAGv3Fykk1a
// Usage 2:
$options = [
'cost' => 11
];
echo password_hash('rasmuslerdorf', PASSWORD_BCRYPT, $options)."\n";
// $2y$11$6DP.V0nO7YI3iSki4qog6OQI5eiO6Jnjsqg7vdnb.JgGIsxniOn4C
To verify a user provided password against an existing hash, you may use the password_verify()
as such:
<?php
// See the password_hash() example to see where this came from.
$hash = '$2y$07$BCryptRequires22Chrcte/VlQH0piJtjXl.0t1XkA8pw9dMXTpOq';
if (password_verify('rasmuslerdorf', $hash)) {
echo 'Password is valid!';
} else {
echo 'Invalid password.';
}
There is a compatibility library on GitHub created based on the source code of the above functions originally written in C, which provides the same functionality. Once the compatibility library is installed, usage is the same as above (minus the shorthand array notation if you are still on the 5.3.x branch).
You can use crypt()
function to generate bcrypt hashes of input strings. This class can automatically generate salts and verify existing hashes against an input. If you are using a version of PHP higher or equal to 5.3.7, it is highly recommended you use the built-in function or the compat library. This alternative is provided only for historical purposes.
class Bcrypt{
private $rounds;
public function __construct($rounds = 12) {
if (CRYPT_BLOWFISH != 1) {
throw new Exception("bcrypt not supported in this installation. See http://php.net/crypt");
}
$this->rounds = $rounds;
}
public function hash($input){
$hash = crypt($input, $this->getSalt());
if (strlen($hash) > 13)
return $hash;
return false;
}
public function verify($input, $existingHash){
$hash = crypt($input, $existingHash);
return $hash === $existingHash;
}
private function getSalt(){
$salt = sprintf('$2a$%02d$', $this->rounds);
$bytes = $this->getRandomBytes(16);
$salt .= $this->encodeBytes($bytes);
return $salt;
}
private $randomState;
private function getRandomBytes($count){
$bytes = '';
if (function_exists('openssl_random_pseudo_bytes') &&
(strtoupper(substr(PHP_OS, 0, 3)) !== 'WIN')) { // OpenSSL is slow on Windows
$bytes = openssl_random_pseudo_bytes($count);
}
if ($bytes === '' && is_readable('/dev/urandom') &&
($hRand = @fopen('/dev/urandom', 'rb')) !== FALSE) {
$bytes = fread($hRand, $count);
fclose($hRand);
}
if (strlen($bytes) < $count) {
$bytes = '';
if ($this->randomState === null) {
$this->randomState = microtime();
if (function_exists('getmypid')) {
$this->randomState .= getmypid();
}
}
for ($i = 0; $i < $count; $i += 16) {
$this->randomState = md5(microtime() . $this->randomState);
if (PHP_VERSION >= '5') {
$bytes .= md5($this->randomState, true);
} else {
$bytes .= pack('H*', md5($this->randomState));
}
}
$bytes = substr($bytes, 0, $count);
}
return $bytes;
}
private function encodeBytes($input){
// The following is code from the PHP Password Hashing Framework
$itoa64 = './ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
$output = '';
$i = 0;
do {
$c1 = ord($input[$i++]);
$output .= $itoa64[$c1 >> 2];
$c1 = ($c1 & 0x03) << 4;
if ($i >= 16) {
$output .= $itoa64[$c1];
break;
}
$c2 = ord($input[$i++]);
$c1 |= $c2 >> 4;
$output .= $itoa64[$c1];
$c1 = ($c2 & 0x0f) << 2;
$c2 = ord($input[$i++]);
$c1 |= $c2 >> 6;
$output .= $itoa64[$c1];
$output .= $itoa64[$c2 & 0x3f];
} while (true);
return $output;
}
}
You can use this code like this:
$bcrypt = new Bcrypt(15);
$hash = $bcrypt->hash('password');
$isGood = $bcrypt->verify('password', $hash);
Alternatively, you may also use the Portable PHP Hashing Framework.
You may also use math.log1p
.
According to the official documentation :
math.log1p(x)
Return the natural logarithm of 1+x (base e). The result is calculated in a way which is accurate for x near zero.
You may convert back to the original value using math.expm1
which returns e
raised to the power x, minus 1.
It seems that you are using the 64-bit version of the tool to install a 32-bit/x86 architecture application. Look for the 32-bit version of the tool here:
C:\Windows\Microsoft.NET\Framework\v4.0.30319
and it should install your 32-bit application just fine.
Pretty Diff will beautify (pretty print) JavaScript in a way that conforms to JSLint and JSHint white space algorithms.
One Idea:
UPDATE tbl_ClientNotes
SET ordering=ISNULL(@ordering, ordering),
title=ISNULL(@title, title),
content=ISNULL(@content, content)
WHERE id=@id
You have to make the UL
inside the div
behave like a block. Try adding
.navigation ul {
display: inline-block;
}
Having 2 elements with the same ID is not valid html according to the W3C specification.
When your CSS selector only has an ID selector (and is not used on a specific context), jQuery uses the native document.getElementById
method, which returns only the first element with that ID.
However, in the other two instances, jQuery relies on the Sizzle selector engine (or querySelectorAll
, if available), which apparently selects both elements. Results may vary on a per browser basis.
However, you should never have two elements on the same page with the same ID. If you need it for your CSS, use a class instead.
If you absolutely must select by duplicate ID, use an attribute selector:
$('[id="a"]');
Take a look at the fiddle: http://jsfiddle.net/P2j3f/2/
Note: if possible, you should qualify that selector with a tag selector, like this:
$('span[id="a"]');
You could also configure mongod to run on start up so that it is automatically running on start up and the dbpath is set upon configuration. To do this try:
mongod --smallfiles --config /etc/mongod.conf
The --smallfiles
tag is there in case you get an error with size. It is, of course, optional. Doing this should solve your problem while also automating your mongodb setup.
Some general notes.
$obj | Select-Object
? $obj | Select-Object -Property *
The latter will show all non-intrinsic, non-compiler-generated properties. The former does not appear to (always) show all Property types (in my tests, it does appear to show the CodeProperty
MemberType
consistently though -- no guarantees here).
Get-Member
does not get static members by default. You also cannot (directly) get them along with the non-static members. That is, using the switch causes only static members to be returned:
PS Y:\Power> $obj | Get-Member -Static
TypeName: System.IsFire.TurnUpProtocol
Name MemberType Definition
---- ---------- ----------
Equals Method static bool Equals(System.Object objA, System.Object objB)
...
Use the -Force
.
The
Get-Member
command uses the Force parameter to add the intrinsic members and compiler-generated members of the objects to the display.Get-Member

ConvertTo-Json
for depth and readable "serialization"I do not necessary recommend saving objects using JSON (use Export-Clixml
instead).
However, you can get a more or less readable output from ConvertTo-Json
, which also allows you to specify depth.
Note that not specifying Depth
implies -Depth 2
PS Y:\Power> ConvertTo-Json $obj -Depth 1
{
"AllowSystemOverload": true,
"AllowLifeToGetInTheWay": false,
"CantAnyMore": true,
"LastResortOnly": true,
...
And if you aren't planning to read it you can -Compress
it (i.e. strip whitespace)
PS Y:\Power> ConvertTo-Json $obj -Depth 420 -Compress
-InputObject
if you can (and are willing)99.9% of the time when using PowerShell: either the performance won't matter, or you don't care about the performance. However, it should be noted that avoiding the pipe when you don't need it can save some overhead and add some speed (piping, in general, is not super-efficient).
That is, if you all you have is a single $obj
handy for printing (and aren't too lazy like me sometimes to type out -InputObject
):
# select is aliased (hardcoded) to Select-Object
PS Y:\Power> select -Property * -InputObject $obj
# gm is aliased (hardcoded) to Get-Member
PS Y:\Power> gm -Force -InputObject $obj
Caveat for Get-Member -InputObject
:
If $obj is a collection (e.g. System.Object[]
), You end up getting information about the collection object itself:
PS Y:\Power> gm -InputObject $obj,$obj2
TypeName: System.Object[]
Name MemberType Definition
---- ---------- ----------
Count AliasProperty Count = Length
...
If you want to Get-Member
for each TypeName
in the collection (N.B. for each TypeName
, not for each object--a collection of N objects with all the same TypeName
will only print 1 table for that TypeName
, not N tables for each object)......just stick with piping it in directly.
UPDATE This used to work (in 2007, I believe), but does not in Excel 2013.
This isn't quite the same, but if it's possible to put 0.4 in one cell (B1, say), and the text value A1 in another cell (C1, say), in cell D1, you can use =B1*INDIRECT(C1), which results in the calculation of 0.4 * A1's value.
So, if A1 = 10, you'd get 0.4*10 = 4
in cell D1. I'll update again if I can find a better 2013 solution, and sorry the Microsoft destroyed the original functionality of INDIRECT!
For a non-VBA solution, use the INDIRECT
formula. It takes a string as an argument and converts it to a cell reference.
For example, =0.4*INDIRECT("A1")
will return the value of 0.4 * the value that's in cell A1 of that worksheet.
If cell A1 was, say, 10, then =0.4*INDIRECT("A1")
would return 4.

Mage::log('your debug message', null, 'yourlog_filename.log');
Refer this Answer
isfar<-load("C:/Users/isfar.RData")
if(is.data.frame(isfar)){
names(isfar)
}
If isfar is a dataframe, this will print out the names of its columns.
If it´s in the global scope it´s better to use:
function foo()
{
alert('foo');
}
var a = 'foo';
window[a]();
than eval()
. Because eval()
is evaaaaaal.

You cannot concatenate raw strings like this. operator+
only works with two std::string
objects or with one std::string
and one raw string (on either side of the operation).
std::string s("...");
s + s; // OK
s + "x"; // OK
"x" + s; // OK
"x" + "x" // error
The easiest solution is to turn your raw string into a std::string
first:
"Do you feel " + std::string(AGE) + " years old?";
Of course, you should not use a macro in the first place. C++ is not C. Use const
or, in C++11 with proper compiler support, constexpr
.
I was running PHPUnit tests on PHP5, and then, I needed to support PHP7 as well. This is what I did:
In composer.json:
"phpunit/phpunit": "~4.8|~5.7"
In my PHPUnit bootstrap file (in my case, /tests/bootstrap.php
):
// PHPUnit 6 introduced a breaking change that
// removed PHPUnit_Framework_TestCase as a base class,
// and replaced it with \PHPUnit\Framework\TestCase
if (!class_exists('\PHPUnit_Framework_TestCase') && class_exists('\PHPUnit\Framework\TestCase'))
class_alias('\PHPUnit\Framework\TestCase', '\PHPUnit_Framework_TestCase');
In other words, this will work for tests written originally for PHPUnit 4 or 5, but then needed to work on PHPUnit 6 as well.

109 - mon dd yyyy (In SQL conversion)
The required format is April 1 2009
so
SELECT DATENAME(MONTH, GETDATE()) + RIGHT(CONVERT(VARCHAR(12), GETDATE(), 109), 9)
Result is:
curl
sends POST requests with the default content type of application/x-www-form-urlencoded
. If you want to send a JSON request, you will have to specify the correct content type header:
$ curl -vX POST http://server/api/v1/places.json -d @testplace.json \
--header "Content-Type: application/json"
But that will only work if the server accepts json input. The .json
at the end of the url may only indicate that the output is json, it doesn't necessarily mean that it also will handle json input. The API documentation should give you a hint on whether it does or not.
The reason you get a 401
and not some other error is probably because the server can't extract the auth_token
from your request.
You need to load a package (like magrittr
or dplyr
) that defines the function first, then it should work.
install.packages("magrittr") # package installations are only needed the first time you use it
install.packages("dplyr") # alternative installation of the %>%
library(magrittr) # needs to be run every time you start R and want to use %>%
library(dplyr) # alternatively, this also loads %>%
The pipe operator %>%
was introduced to "decrease development time and to improve readability and maintainability of code."
But everybody has to decide for himself if it really fits his workflow and makes things easier.
For more information on magrittr
, click here.
Not using the pipe %>%
, this code would return the same as your code:
words <- colnames(as.matrix(dtm))
words <- words[nchar(words) < 20]
words
EDIT: (I am extending my answer due to a very useful comment that was made by @Molx)
Despite being from
magrittr
, the pipe operator is more commonly used with the packagedplyr
(which requires and loadsmagrittr
), so whenever you see someone using%>%
make sure you shouldn't loaddplyr
instead.

One way to deal with asynchronous work like this is to use a callback function, eg:
function firstFunction(_callback){
// do some asynchronous work
// and when the asynchronous stuff is complete
_callback();
}
function secondFunction(){
// call first function and pass in a callback function which
// first function runs when it has completed
firstFunction(function() {
console.log('huzzah, I\'m done!');
});
}
As per @Janaka Pushpakumara's suggestion, you can now use arrow functions to achieve the same thing. For example:
firstFunction(() => console.log('huzzah, I\'m done!'))
Update: I answered this quite some time ago, and really want to update it. While callbacks are absolutely fine, in my experience they tend to result in code that is more difficult to read and maintain. There are situations where I still use them though, such as to pass in progress events and the like as parameters. This update is just to emphasise alternatives.
Also the original question doesn't specificallty mention async, so in case anyone is confused, if your function is synchronous, it will block when called. For example:
doSomething()
// the function below will wait until doSomething completes if it is synchronous
doSomethingElse()
If though as implied the function is asynchronous, the way I tend to deal with all my asynchronous work today is with async/await. For example:
const secondFunction = async () => {
const result = await firstFunction()
// do something else here after firstFunction completes
}
IMO, async/await makes your code much more readable than using promises directly (most of the time). If you need to handle catching errors then use it with try/catch. Read about it more here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function .
Combine the mousemove and window.onbeforeunload event :- I used for set TimeOut for Audit Table.
$(document).ready(function () {
var checkCloseX = 0;
$(document).mousemove(function (e) {
if (e.pageY <= 5) {
checkCloseX = 1;
}
else { checkCloseX = 0; }
});
window.onbeforeunload = function (event) {
if (event) {
if (checkCloseX == 1) {
//alert('1111');
$.ajax({
type: "GET",
url: "Account/SetAuditHeaderTimeOut",
dataType: "json",
success: function (result) {
if (result != null) {
}
}
});
}
}
};
});
I think that replacing:
List<String> list = Arrays.asList(split);
with
List<String> list = new ArrayList<String>(Arrays.asList(split));
resolves the problem.
You should use thenReturn
or doReturn
when you know the return value at the time you mock a method call. This defined value is returned when you invoke the mocked method.
thenReturn(T value)
Sets a return value to be returned when the method is called.
@Test
public void test_return() throws Exception {
Dummy dummy = mock(Dummy.class);
int returnValue = 5;
// choose your preferred way
when(dummy.stringLength("dummy")).thenReturn(returnValue);
doReturn(returnValue).when(dummy).stringLength("dummy");
}
Answer
is used when you need to do additional actions when a mocked method is invoked, e.g. when you need to compute the return value based on the parameters of this method call.
Use
doAnswer()
when you want to stub a void method with genericAnswer
.Answer specifies an action that is executed and a return value that is returned when you interact with the mock.
@Test
public void test_answer() throws Exception {
Dummy dummy = mock(Dummy.class);
Answer<Integer> answer = new Answer<Integer>() {
public Integer answer(InvocationOnMock invocation) throws Throwable {
String string = invocation.getArgumentAt(0, String.class);
return string.length() * 2;
}
};
// choose your preferred way
when(dummy.stringLength("dummy")).thenAnswer(answer);
doAnswer(answer).when(dummy).stringLength("dummy");
}
In Matlab I did something similar using the delaunay
function on the x
, y
coords only (not the z
), then plotting with trimesh
or trisurf
, using z
as the height.
SciPy has the Delaunay class, which is based on the same underlying QHull library that the Matlab's delaunay
function is, so you should get identical results.
From there, it should be a few lines of code to convert this Plotting 3D Polygons in python-matplotlib example into what you wish to achieve, as Delaunay
gives you the specification of each triangular polygon.
If I recall correctly Twig doesn't support ||
and &&
operators, but requires or
and and
to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.
{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}
Expressions
Expressions can be used in {% blocks %} and ${ expressions }.
Operator Description
== Does the left expression equal the right expression?
+ Convert both arguments into a number and add them.
- Convert both arguments into a number and substract them.
* Convert both arguments into a number and multiply them.
/ Convert both arguments into a number and divide them.
% Convert both arguments into a number and calculate the rest of the integer division.
~ Convert both arguments into a string and concatenate them.
or True if the left or the right expression is true.
and True if the left and the right expression is true.
not Negate the expression.
For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:
{% if (foo and bar) or (fizz and (foo + bar == 3)) %}
Below is a fully functional example of what I believe you're trying to do (with a functional snippet).
Based on your question, you seem to be modifying 1 property in state
for all of your elements. That's why when you click on one, all of them are being changed.
In particular, notice that the state tracks an index of which element is active. When MyClickable
is clicked, it tells the Container
its index, Container
updates the state
, and subsequently the isActive
property of the appropriate MyClickable
s.

In response to a comment about a "loop" version, I believe the question is about rendering an array of MyClickable
elements. We won't use a loop, but map, which is typical in React + JSX. The following should give you the same result as above, but it works with an array of elements.
// New render method for `Container`
render() {
const clickables = [
{ name: "a" },
{ name: "b" },
{ name: "c" },
]
return <div>
{ clickables.map(function(clickable, i) {
return <MyClickable key={ clickable.name }
name={ clickable.name }
index={ i }
isActive={ this.state.activeIndex === i }
onClick={ this.handleClick }
/>
} )
}
</div>
}
Here is an example of initializing a boolean[][]:
const n = 8; // or some dynamic value
const palindrome: boolean[][] = new Array(n)
.fill(false)
.map(() => new Array(n)
.fill(false));
info = [];
info[0] = 'hi';
info[1] = 'hello';
$.ajax({
type: "POST",
data: {info:info},
url: "index.php",
success: function(msg){
$('.answer').html(msg);
}
});
I simplified my source code (whose original version is OOP and uses a configuration file), to give you an alternative solution to @EliasStrehle's one, without using the dictConfig (thus easiest to integrate with existing source code):
import logging
import sys
def create_stream_handler(stream, formatter, level, message_filter=None):
handler = logging.StreamHandler(stream=stream)
handler.setLevel(level)
handler.setFormatter(formatter)
if message_filter:
handler.addFilter(message_filter)
return handler
def configure_logger(logger: logging.Logger, enable_console: bool = True, enable_file: bool = True):
if not logger.handlers:
if enable_console:
message_format: str = '{asctime:20} {name:16} {levelname:8} {message}'
date_format: str = '%Y/%m/%d %H:%M:%S'
level: int = logging.DEBUG
formatter = logging.Formatter(message_format, date_format, '{')
# Configures error output (from Warning levels).
error_output_handler = create_stream_handler(sys.stderr, formatter,
max(level, logging.WARNING))
logger.addHandler(error_output_handler)
# Configures standard output (from configured Level, if lower than Warning,
# and excluding everything from Warning and higher).
if level < logging.WARNING:
standard_output_filter = lambda record: record.levelno < logging.WARNING
standard_output_handler = create_stream_handler(sys.stdout, formatter, level,
standard_output_filter)
logger.addHandler(standard_output_handler)
if enable_file:
message_format: str = '{asctime:20} {name:16} {levelname:8} {message}'
date_format: str = '%Y/%m/%d %H:%M:%S'
level: int = logging.DEBUG
output_file: str = '/tmp/so_test.log'
handler = logging.FileHandler(output_file)
formatter = logging.Formatter(message_format, date_format, '{')
handler.setLevel(level)
handler.setFormatter(formatter)
logger.addHandler(handler)
This is a very simple way to test it:
logger: logging.Logger = logging.getLogger('MyLogger')
logger.setLevel(logging.DEBUG)
configure_logger(logger, True, True)
logger.debug('Debug message ...')
logger.info('Info message ...')
logger.warning('Warning ...')
logger.error('Error ...')
logger.fatal('Fatal message ...')
IMPORTANT:
If you don't set the encoding, many softwares can break. git is a very popular example.
Set-Content "your_ignore_file.txt" .gitignore -Encoding utf8
this is case-sensitive and forces utf8 encoding!

Would like to add some theoretical concept to Imanou Petit’s answer, so that one can understand how auto layout works.
To understand auto layout consider your view as rubber's object which is shrinked initially.
To place an object on screen we need 4 mandatory things :
X coordinate of object (horizontal position).
Y coordinate of object (vertical position )
Object’s Width
Object’s Height.
1 X coordinate: There are multiple ways of giving x coordinates to a view.
Such as Leading constraint, Trailing constraint , Horizontally centre etc.
2 Y coordinate: There are multiple ways of giving y coordinates to a view :
Such as Top constraint, Bottom constraint , Vertical centre etc.
3 Object's width: There are two ways of giving width constrain to a view :
a. Add fixed width constraint (consider this constraint as iron rod of fixed width and you have hooked your rubber’s object horizontally with it so rubber’s object don’t shrink or expand)
b. Do not add any width constraint but add x coordinate constraint to both end of view trailing and leading, these two constraints will expand/shrink your rubber’s object by pulling/pushing it from both end, leading and trailing.
4 Object's height: Similar to width, there are two ways of giving height constraint to a view as well :
a. Add fixed height constraint (consider this constraints as iron rod of fixed height and you have hooked your rubber’s object vertically with it so rubber’s object don’t shrink or expand)
b. Do not add any height constraint but add x coordinate constraint to both end of view top and bottom, these two constraints will expand/shrink your rubber’s object pulling/pushing it from both end, top and bottom.

It is an extra part to the answer to this question here but I thought it might be useful. As many people mentioned, Visual Studio Code has the OUTLINE part which provides the ability to browse to different function and show them on the side.
I also wanted to add that if you check the follow cursor mark, it highlights that function name in the OUTLINE view, which is very helpful in browsing and seeing which function you are in.
Some more details in relation with the response from Cody Gray. As it took me some time to digest it I though it might be usefull to others.
First, some definitions:
Bar
is a TypeName in Public Class Bar
, or in Dim Foo as Bar
. TypeNames could be seen as "labels" used in the code to tell the compiler which type definition to look for in a dictionary where all available types would be described.System.Type
objects which contain a value. This value indicates a type; just like a String
would take some text or an Int
would take a number, except we are storing types instead of text or numbers. Type
objects contain the type definitions, as well as its corresponding TypeName.Second, the theory:
Foo.GetType()
returns a Type
object which contains the type for the variable Foo
. In other words, it tells you what Foo
is an instance of.GetType(Bar)
returns a Type
object which contains the type for the TypeName Bar
.In some instances, the type an object has been Cast
to is different from the type an object was first instantiated from. In the following example, MyObj is an Integer
cast into an Object
:
Dim MyVal As Integer = 42
Dim MyObj As Object = CType(MyVal, Object)
So, is MyObj
of type Object
or of type Integer
? MyObj.GetType()
will tell you it is an Integer
.
Type Of Foo Is Bar
feature, which allows you to ascertain a variable Foo
is compatible with a TypeName Bar
. Type Of MyObj Is Integer
and Type Of MyObj Is Object
will both return True. For most cases, TypeOf will indicate a variable is compatible with a TypeName if the variable is of that Type or a Type that derives from it.
More info here: https://docs.microsoft.com/en-us/dotnet/visual-basic/language-reference/operators/typeof-operator#remarksThe test below illustrate quite well the behaviour and usage of each of the mentionned keywords and properties.

Debug.Print(MyValDble.GetType = GetType(Double)) '# Returns True
Debug.Print(MyValDble.GetType = GetType(Object)) 'Returns False
Debug.Print(MyObj.GetType = GetType(Integer)) 'Returns False

Debug.Print(TypeOf MyObj Is Integer) 'Returns False

EDIT
You can also use Information.TypeName(Object)
to get the TypeName of a given object. For example,
Dim Foo as Bar
Dim Result as String
Result = TypeName(Foo)
Debug.Print(Result) 'Will display "Bar"
As help to anybody that had the same problem as me, I accidentally mistyped the implementation type instead of the interface e.g.

instead of
var mockFileBrowser = new Mock<IFileBrowser>();
You can easily do this via ant. Here is a build.xml file for doing this
<project name="genTestReport" default="gen" basedir=".">
<description>
Generate the HTML report from JUnit XML files
</description>
<target name="gen">
<property name="genReportDir" location="${basedir}/unitTestReports"/>
<delete dir="${genReportDir}"/>
<mkdir dir="${genReportDir}"/>
<junitreport todir="${basedir}/unitTestReports">
<fileset dir="${basedir}">
<include name="**/TEST-*.xml"/>
</fileset>
<report format="frames" todir="${genReportDir}/html"/>
</junitreport>
</target>
</project>
This will find files with the format TEST-*.xml and generate reports into a folder named unitTestReports.
To run this (assuming the above file is called buildTestReports.xml) run the following command in the terminal:
ant -buildfile buildTestReports.xml
For reasons I do not understand, you cannot directly add the contents of one Set to another with a built-in operation. Operations like union, intersect, merge, etc... are pretty basic set operations, but are not built-in. Fortunately, you can construct these all yourself fairly easily.
So, to implement a merge operation (merging the contents of one Set into another or one Map into another), you can do this with a single .forEach()
line:
var s = new Set([1,2,3]);
var t = new Set([4,5,6]);
t.forEach(s.add, s);
console.log(s); // 1,2,3,4,5,6
And, for a Map
, you could do this:
var s = new Map([["key1", 1], ["key2", 2]]);
var t = new Map([["key3", 3], ["key4", 4]]);
t.forEach(function(value, key) {
s.set(key, value);
});
Or, in ES6 syntax:
t.forEach((value, key) => s.set(key, value));
FYI, if you want a simple subclass of the built-in Set
object that contains a .merge()
method, you can use this:
// subclass of Set that adds new methods
// Except where otherwise noted, arguments to methods
// can be a Set, anything derived from it or an Array
// Any method that returns a new Set returns whatever class the this object is
// allowing SetEx to be subclassed and these methods will return that subclass
// For this to work properly, subclasses must not change behavior of SetEx methods
//
// Note that if the contructor for SetEx is passed one or more iterables,
// it will iterate them and add the individual elements of those iterables to the Set
// If you want a Set itself added to the Set, then use the .add() method
// which remains unchanged from the original Set object. This way you have
// a choice about how you want to add things and can do it either way.
class SetEx extends Set {
// create a new SetEx populated with the contents of one or more iterables
constructor(...iterables) {
super();
this.merge(...iterables);
}
// merge the items from one or more iterables into this set
merge(...iterables) {
for (let iterable of iterables) {
for (let item of iterable) {
this.add(item);
}
}
return this;
}
// return new SetEx object that is union of all sets passed in with the current set
union(...sets) {
let newSet = new this.constructor(...sets);
newSet.merge(this);
return newSet;
}
// return a new SetEx that contains the items that are in both sets
intersect(target) {
let newSet = new this.constructor();
for (let item of this) {
if (target.has(item)) {
newSet.add(item);
}
}
return newSet;
}
// return a new SetEx that contains the items that are in this set, but not in target
// target must be a Set (or something that supports .has(item) such as a Map)
diff(target) {
let newSet = new this.constructor();
for (let item of this) {
if (!target.has(item)) {
newSet.add(item);
}
}
return newSet;
}
// target can be either a Set or an Array
// return boolean which indicates if target set contains exactly same elements as this
// target elements are iterated and checked for this.has(item)
sameItems(target) {
let tsize;
if ("size" in target) {
tsize = target.size;
} else if ("length" in target) {
tsize = target.length;
} else {
throw new TypeError("target must be an iterable like a Set with .size or .length");
}
if (tsize !== this.size) {
return false;
}
for (let item of target) {
if (!this.has(item)) {
return false;
}
}
return true;
}
}
module.exports = SetEx;
This is meant to be in it's own file setex.js that you can then require()
into node.js and use in place of the built-in Set.
You seem to be using grep()
like the Unix grep
utility, which is wrong.
Perl's grep()
in scalar context evaluates the expression for each element of a list and returns the number of times the expression was true.
So when $match
contains any "true" value, grep($match, @array)
in scalar context will always return the number of elements in @array
.
Instead, try using the pattern matching operator:
if (grep /$match/, @array) {
print "found it\n";
}
Although they vary slightly as to how they retrieve a height value, i.e some would calculate the whole element including padding, margin, scrollbar, etc and others would just calculate the element in its raw form.
You can try these ones:
javascript:
var myDiv = document.getElementById("myDiv");
myDiv.clientHeight;
myDiv.scrollHeight;
myDiv.offsetHeight;
or in jquery:
$("#myDiv").height();
$("#myDiv").innerHeight();
$("#myDiv").outerHeight();

}
dependencies {
compile 'com.android.support:appcompat-v7:+'
compile 'com.google.android.gms:play-services:+'
compile 'com.android.support:multidex:1.0.1'
}
write a class EnableMultiDex
like below
import android.content.Context;
import android.support.multidex.MultiDexApplication;
public class EnableMultiDex extends MultiDexApplication {
private static EnableMultiDex enableMultiDex;
public static Context context;
public EnableMultiDex(){

}
public static EnableMultiDex getEnableMultiDexApp() {
return enableMultiDex;
}
@Override
public void onCreate() {
super.onCreate();
context = getApplicationContext();
}
}
and in AndroidManifest.xml
write this className inside Application tag
<application
android:name="YourPakageName.EnableMultiDex"
android:hardwareAccelerated="true"
android:icon="@drawable/wowio_launch_logo"
android:label="@string/app_name"

If I understand your question correctly, I've made a fiddle that has this working correctly. This issue is with how you're assigning the event handlers and as others have said you have over riding event handlers. The current jQuery best practice is to use on()
to register event handlers. Here's a link to the jQuery docs about on
: link
Your original solution was pretty close but the way you added the event handlers is a bit confusing. It's considered best practice to not add events to HTML elements. I recommend reading up on Unobstrusive JavaScript.
Here's the JavaScript code. I added a counter variable so you can see that it is working correctly.
$('#answer').on('click', function() {
feedback('hey there');
});
var counter = 0;
function feedback(message) {
$('#feedback').remove();
$('.answers').append('<div id="feedback">' + message + ' ' + counter + '</div>');
counter++;
}

when you invoke a function , it is termed 'calling' a function . For eg , suppose you've defined a function that finds the average of two numbers like this-
def avgg(a,b) :
return (a+b)/2;
now, to call the function , you do like this .
x=avgg(4,6)
print x
value of x will be 5 .
Try what's below. It will help you...
Fiddle : http://jsfiddle.net/RYh7U/146/
Script :
if(dateCheck("02/05/2013","02/09/2013","02/07/2013"))
alert("Availed");
else
alert("Not Availed");
function dateCheck(from,to,check) {
var fDate,lDate,cDate;
fDate = Date.parse(from);
lDate = Date.parse(to);
cDate = Date.parse(check);
if((cDate <= lDate && cDate >= fDate)) {
return true;
}
return false;
}
I find that Wikipedia can be a great source of information about such tools, especially for comparison tables. There's a page on UML tools. See in particular the reverse engineered languages column.
Just write:
private static double balance = 0;
and you could also write those like that:
private static int id = 0;
private static double annualInterestRate = 0;
public static java.util.Date dateCreated;

From RFC 1945 (HTTP/1.0) and RFC 2617 (HTTP Authentication referenced by HTTP/1.1)
The realm attribute (case-insensitive) is required for all authentication schemes which issue a challenge. The realm value (case-sensitive), in combination with the canonical root URL of the server being accessed, defines the protection space. These realms allow the protected resources on a server to be partitioned into a set of protection spaces, each with its own authentication scheme and/or authorization database. The realm value is a string, generally assigned by the origin server, which may have additional semantics specific to the authentication scheme.
In short, pages in the same realm should share credentials. If your credentials work for a page with the realm "My Realm", it should be assumed that the same username and password combination should work for another page with the same realm.
Under the help menu, there should be a menu item labeled "About Eclipse" I can't say with absolute precision because I'm using STS which is the same thing but my label is different.
In the dialog box that opens after you click the relevant about menu item there should be an installation details button in the lower left hand corner.
The version of Java that you're running Eclipse against ought to be in "System properties:" under the "Configuration" tab.
The answer is in the JavaDoc of the equals()
method:
Unlike
compareTo
, this method considers twoBigDecimal
objects equal only if they are equal in value and scale (thus 2.0 is not equal to 2.00 when compared by this method).
In other words: equals()
checks if the BigDecimal
objects are exactly the same in every aspect. compareTo()
"only" compares their numeric value.
As to why equals()
behaves this way, this has been answered in this SO question.
Use:
SELECT t1.Notes,
t2.Name
FROM Table1 t1
JOIN Table2 t2 ON t1.Notes LIKE CONCAT('%', t2.Name ,'%')
You should try using isinstance()
if isinstance(object, list):
## DO what you want
In your case
if isinstance(tmpDict[key], list):
## DO SOMETHING
To elaborate:
x = [1,2,3]
if type(x) == list():
print "This wont work"
if type(x) == list: ## one of the way to see if it's list
print "this will work"
if type(x) == type(list()):
print "lets see if this works"
if isinstance(x, list): ## most preferred way to check if it's list
print "This should work just fine"
The difference between isinstance()
and type()
though both seems to do the same job is that isinstance()
checks for subclasses in addition, while type()
doesn’t.
I use the @Adi-lester answer and add some methods.

}
By adding the class block--invisible
the whole Elements will not be clickable but all Elements behind it will be because of the pointer-events:none
which is supported by all major browsers (no IE < 11).

FYI, this is of little or no use to the OP but it may be of use to other readers (please do not downvote, I'm aware of this).
As a somewhat ridiculous but interesting exercise, wanted to see if I could use python functional programming to replace multiple chars. I'm pretty sure this does NOT beat just calling replace() twice. And if performance was an issue, you could easily beat this in rust, C, julia, perl, java, javascript and maybe even awk. It uses an external 'helpers' package called pytoolz, accelerated via cython (cytoolz, it's a pypi package).
from cytoolz.functoolz import compose
from cytoolz.itertoolz import chain,sliding_window
from itertools import starmap,imap,ifilter
from operator import itemgetter,contains
text='&hello#hi&yo&'
char_index_iter=compose(partial(imap, itemgetter(0)), partial(ifilter, compose(partial(contains, '#&'), itemgetter(1))), enumerate)
print '\\'.join(imap(text.__getitem__, starmap(slice, sliding_window(2, chain((0,), char_index_iter(text), (len(text),))))))
I'm not even going to explain this because no one would bother using this to accomplish multiple replace. Nevertheless, I felt somewhat accomplished in doing this and thought it might inspire other readers or win a code obfuscation contest.
The correct syntax is mysql> SET @@global.group_concat_max_len = integer;
If you do not have the privileges to do this on the server where your database resides then use a query like:
mySQL="SET @@session.group_concat_max_len = 10000;"
or a different value.
Next line:
SET objRS = objConn.Execute(mySQL)
your variables may be different.
then
mySQL="SELECT GROUP_CONCAT(......);"
etc
I use the last version since I do not have the privileges to change the default value of 1024 globally (using cPanel).
Hope this helps.

I changed you worksheet to play with (see above for the new Sub). This probably does not suite your needs directly, but hopefully it will demonstrate the conept behind what I think you want to do. Please keep in mind that this code does not follow all the coding best preactices I would recommend (e.g. validating the time is actually a TIME and not some random other data type).

As mentioned in a previous reply, this generally comes when compiling copy pasted code. If you have a bash shell, the following command generally works:
iconv -f utf-8 -t ascii//translit input.c > output.c
array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
array.each { |x| puts x if x % 2 == 0 }
2 4 6 8 10
Just another way of doing it, (or if you are using express) add the condition in code:
if(yourCondition)
{
System.Diagnostics.Debugger.Break();
}
Hmm, I think I misunderstand the question but I'm going to risk it. What's wrong with the following straightforward method?
public static void CopyFilesRecursively(DirectoryInfo source, DirectoryInfo target) {
foreach (DirectoryInfo dir in source.GetDirectories())
CopyFilesRecursively(dir, target.CreateSubdirectory(dir.Name));
foreach (FileInfo file in source.GetFiles())
file.CopyTo(Path.Combine(target.FullName, file.Name));
}
EDIT Since this posting has garnered an impressive number of downvotes for such a simple answer to an equally simple question, let me add an explanation. Please read this before downvoting.
First of all, this code is not intendend as a drop-in replacement to the code in the question. It is for illustration purpose only.
Microsoft.VisualBasic.Devices.Computer.FileSystem.CopyDirectory
does some additional correctness tests (e.g. whether the source and target are valid directories, whether the source is a parent of the target etc.) that are missing from this answer. That code is probably also more optimized.
That said, the code works well. It has (almost identically) been used in a mature software for years. Apart from the inherent fickleness present with all IO handlings (e.g. what happens if the user manually unplugs the USB drive while your code is writing to it?), there are no known problems.
In particular, I’d like to point out that the use of recursion here is absolutely not a problem. Neither in theory (conceptually, it’s the most elegant solution) nor in practice: this code will not overflow the stack. The stack is large enough to handle even deeply nested file hierarchies. Long before stack space becomes a problem, the folder path length limitation kicks in.
Notice that a malicious user might be able to break this assumption by using deeply-nested directories of one letter each. I haven’t tried this. But just to illustrate the point: in order to make this code overflow on a typical computer, the directories would have to be nested a few thousand times. This is simply not a realistic scenario.
If you want to get the file names only without the rest of the commit message you can use:
git log --name-only --pretty=format: <branch name>
This can then be extended to use the various options that contain the file name:
git log --name-status --pretty=format: <branch name>
git log --stat --pretty=format: <branch name>
One thing to note when using this method is that there are some blank lines in the output that will have to be ignored. Using this can be useful if you'd like to see the files that have been changed on a local branch, but is not yet pushed to a remote branch and there is no guarantee the latest from the remote has already been pulled in. For example:
git log --name-only --pretty=format: my_local_branch --not origin/master
Would show all the files that have been changed on the local branch, but not yet merged to the master branch on the remote.
try: typeof(predQuery[preId])=='undefined'
or more generally: typeof(yourArray[yourIndex])=='undefined'
You're comparing "undefined" to undefined, which returns false =)
"==" always compare the memory location or object references of the values. equals method always compare the values. But equals also indirectly uses the "==" operator to compare the values.
Integer uses Integer cache to store the values from -128 to +127. If == operator is used to check for any values between -128 to 127 then it returns true. for other than these values it returns false .

You need to stringify the json, not calling toString
var buf = Buffer.from(JSON.stringify(obj));
And for converting string to json obj :
var temp = JSON.parse(buf.toString());
File.Create(string)
returns an instance of the FileStream
class. You can call the Stream.Close()
method on this object in order to close it and release resources that it's using:
var myFile = File.Create(myPath);
myFile.Close();
However, since FileStream
implements IDisposable
, you can take advantage of the using
statement (generally the preferred way of handling a situation like this). This will ensure that the stream is closed and disposed of properly when you're done with it:
using (var myFile = File.Create(myPath))
{
// interact with myFile here, it will be disposed automatically
}
Yes, I try to follow it as closely as possible.
I don't follow any other coding standards.
