Use mysqli as mysql is depricating
<?php
$mysqli = new mysqli("localhost", "yourUsername", "yourPassword", "yourDB");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
// Conside employee table with id,name,designation
$query = "INSERT INTO myCity VALUES (NULL, 'Ram', 'Developer')";
$mysqli->query($query);
printf ("New Record has id %d.\n", $mysqli->insert_id);
/* close connection */
$mysqli->close();
?>
There is one issue with the top voted answer here which recommends this regex:
/^[a-z ,.'-]+$/i
It takes spaces only as a valid name!
The best solution in my opinion is to add a negative look forward to the beginning:
^(?!\s)([a-z ,.'-]+)$/i
Totally agree with @Greg Hewgill
And if you path includes spaces, you might use, try adding with apostrophe '
or `
git diff 'MyProject/My Folder/My Sub Folder/file_2.rb'
In my limited experience with the following details.throws is a declaration that declares multiple exceptions that may occur but do not necessarily occur, throw is an action that can throw only one exception, typically a non-runtime exception, try catch is a block that catches exceptions that can be handled when an exception occurs in a method,this exception can be thrown.An exception can be understood as a responsibility that should be taken care of by the behavior that caused the exception, rather than by its upper callers. I hope my answer will help you
You can use isTRUE
for such cases. isTRUE
is the same as { is.logical(x) && length(x) == 1 && !is.na(x) && x }
If you use shiny there you could use isTruthy
which covers the following cases:
FALSE
NULL
""
An empty atomic vector
An atomic vector that contains only missing values
A logical vector that contains all FALSE or missing values
An object of class "try-error"
A value that represents an unclicked actionButton()
When you want to read a file with a different configuration than the default one, feel free to use either mpu.aws.s3_read(s3path)

There is no need for extra CSS, and there are multiple centering methods in Bootstrap 4:
text-center
for center display:inline
elementsmx-auto
for centering display:block
elements inside display:flex
(d-flex)offset-*
or mx-auto
can be used to center grid columnsjustify-content-center
on row
to center grid columnsmx-auto
(auto x-axis margins) will center inside display:flex
elements that have a defined width, (%, vw, px, etc..). Flexbox is used by default on grid columns, so there are also various centering methods.
In your case, you can simply mx-auto
to the cards.
This worked for me:

You can do this with the scp
command, which uses the ssh protocol to copy files across machines. It extends the syntax of cp
to allow references to other systems:
scp username1@hostname1:/path/to/file username2@hostname2:/path/to/other/file
Copy something from this machine to some other machine:
scp /path/to/local/file username@hostname:/path/to/remote/file
Copy something from another machine to this machine:
scp username@hostname:/path/to/remote/file /path/to/local/file
Copy with a port number specified:
scp -P 1234 username@hostname:/path/to/remote/file /path/to/local/file
You can use combination of View, Icon and TextInput like so:
<View style={styles.searchSection}>
<Icon style={styles.searchIcon} name="ios-search" size={20} color="#000"/>
<TextInput
style={styles.input}
placeholder="User Nickname"
onChangeText={(searchString) => {this.setState({searchString})}}
underlineColorAndroid="transparent"
/>
</View>
and use flex-direction for styling
searchSection: {
flex: 1,
flexDirection: 'row',
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#fff',
},
searchIcon: {
padding: 10,
},
input: {
flex: 1,
paddingTop: 10,
paddingRight: 10,
paddingBottom: 10,
paddingLeft: 0,
backgroundColor: '#fff',
color: '#424242',
},
Icons were taken from "react-native-vector-icons"
Can't beat Eric Leschinski's awesomely detailed answer, but here's a quick workaround to the original question that I don't think has been mentioned yet - put the string in a list and use .isin
instead of ==
For example:
import pandas as pd
import numpy as np
df = pd.DataFrame({"Name": ["Peter", "Joe"], "Number": [1, 2]})
# Raises warning using == to compare different types:
df.loc[df["Number"] == "2", "Number"]
# No warning using .isin:
df.loc[df["Number"].isin(["2"]), "Number"]
Some things to check:
Can you change to unrestricted?
Set-ExecutionPolicy Unrestricted
Is the group policy set?
Computer Configuration\Administrative Templates\Windows Components\Windows PowerShell
User Configuration\Administrative Templates\Windows Components\Windows PowerShell
Also, how are you calling Script.ps1?
Does this allow it to run?
powershell.exe -executionpolicy bypass -file .\Script.ps1
Okay so you are trying to get a bitmap from a file? Title says URL. Anyways, when you are getting files from external storage in Android you should never use a direct path. Instead call getExternalStorageDirectory() like so:
File bitmapFile = new File(Environment.getExternalStorageDirectory() + "/" + PATH_TO_IMAGE);
Bitmap bitmap = BitmapFactory.decodeFile(bitmapFile);
getExternalStorageDirectory() gives you the path to the SD card. Also you need to declare the WRITE_EXTERNAL_STORAGE permission in the Manifest.
This is one way without using time a zone:
LocalDateTime now = LocalDateTime.now();
long epoch = (now.getLong(ChronoField.EPOCH_DAY) * 86400000) + now.getLong(ChronoField.MILLI_OF_DAY);
This seems quick for me :
comm -1 -3 <(sort file1.txt) <(sort file2.txt) > output.txt

SQL Server 2017 and Later Versions
If you are working on SQL Server 2017 or later versions, you can use built-in SQL Server Function STRING_AGG to create the comma delimited list:
DECLARE @Table1 TABLE(ID INT, Value INT);
INSERT INTO @Table1 VALUES (1,100),(1,200),(1,300),(1,400);
SELECT ID , STRING_AGG([Value], ', ') AS List_Output

I'm always running tests against an in-memory DB (HSQLDB or Derby) for these reasons:
The in-memory DB is loaded with fresh data once the tests start and after most tests, I invoke ROLLBACK to keep it stable. ALWAYS keep the data in the test DB stable! If the data changes all the time, you can't test.
The data is loaded from SQL, a template DB or a dump/backup. I prefer dumps if they are in a readable format because I can put them in VCS. If that doesn't work, I use a CSV file or XML. If I have to load enormous amounts of data ... I don't. You never have to load enormous amounts of data :) Not for unit tests. Performance tests are another issue and different rules apply.
htons
is host-to-network short
This means it works on 16-bit short integers. i.e. 2 bytes.
This function swaps the endianness of a short.
Your number starts out at:
0001 0011 1000 1001 = 5001
When the endianness is changed, it swaps the two bytes:
1000 1001 0001 0011 = 35091
What you're trying to do is to monitor the property of attribute in directive. You can watch the property of attribute changes using $observe() as follows:
angular.module('myApp').directive('conversation', function() {
return {
restrict: 'E',
replace: true,
compile: function(tElement, attr) {
attr.$observe('typeId', function(data) {
console.log("Updated data ", data);
}, true);
}
};
});
Keep in mind that I used the 'compile' function in the directive here because you haven't mentioned if you have any models and whether this is performance sensitive.
If you have models, you need to change the 'compile' function to 'link' or use 'controller' and to monitor the property of a model changes, you should use $watch(), and take of the angular {{}} brackets from the property, example:
<conversation style="height:300px" type="convo" type-id="some_prop"></conversation>
And in the directive:
angular.module('myApp').directive('conversation', function() {
return {
scope: {
typeId: '=',
},
link: function(scope, elm, attr) {
scope.$watch('typeId', function(newValue, oldValue) {
if (newValue !== oldValue) {
// You actions here
console.log("I got the new value! ", newValue);
}
}, true);
}
};
});
jeues answer helped me nothing :-( after hours I finally found the solution for my system and I think this will help other people too. I had to set the LD_LIBRARY_PATH like this:
export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/
after that everything worked very well, even without any "-extension RANDR" switch.
With SQLServer 2005 Express, what I found was that even with autocommit off, insertions into a Db table were committed without my actually issuing a commit command from the Management Studio session. The only difference was, when autocommit was off, I could roll back all the insertions; with *autocommit on, I could not.* Actually, I was wrong. With autocommit mode off, I see the changes only in the QA (Query Analyzer) window from which the commands were issued. If I popped a new QA (Query Analyzer) window, I do not see the changes made by the first window (session), i.e. they are NOT committed! I had to issue explicit commit or rollback commands to make changes visible to other sessions(QA windows) -- my bad! Things are working correctly.
The solution is pretty simple.

For anyone else who runs into this...
Version 1.2.0 of this plugin (current as of this post) doesn't quite work in all cases as documented with Bootstrap 3.0, but it does with a minor workaround.
Specifically, if using an input with icon, the HTML markup is of course slightly different as class names have changed:
<div class="input-group" data-datepicker="true">
<input name="date" type="text" class="form-control" />
<span class="input-group-addon"><i class="icon-calendar"></i></span>
</div>
It seems because of this, you need to use a selector that points directly to the input element itself NOT the parent container (which is what the auto generated HTML on the demo page suggests).
$('*[data-datepicker="true"] input[type="text"]').datepicker({
todayBtn: true,
orientation: "top left",
autoclose: true,
todayHighlight: true
});
Having done this you will probably also want to add a listener for clicking/tapping on the icon so it sets focus on the text input when clicked (which is the behaviour when using this plugin with TB 2.x by default).
$(document).on('touch click', '*[data-datepicker="true"] .input-group-addon', function(e){
$('input[type="text"]', $(this).parent()).focus();
});
NB: I just use a data-datepicker boolean attribute because the class name 'datepicker' is reserved by the plugin and I already use 'date' for styling elements.

URLs are not resolved based on the file structure in the server side. URLs are resolved based on the real public web addresses of the resources in question. It's namely the webbrowser who has got to invoke them, not the webserver.
There are several ways to soften the pain:
JSF EL offers a shorthand to ${pageContext.request}
in flavor of #{request}
:
<li><a href="#{request.contextPath}/index.xhtml">Home</a></li>
<li><a href="#{request.contextPath}/about_us.xhtml">About us</a></li>
You can if necessary use <c:set>
tag to make it yet shorter. Put it somewhere in the master template, it'll be available to all pages:
<c:set var="root" value="#{request.contextPath}/" />
...
<li><a href="#{root}index.xhtml">Home</a></li>
<li><a href="#{root}about_us.xhtml">About us</a></li>
JSF 2.x offers the <h:link>
which can take a view ID relative to the context root in outcome
and it will append the context path and FacesServlet
mapping automatically:
<li><h:link value="Home" outcome="index" /></li>
<li><h:link value="About us" outcome="about_us" /></li>
HTML offers the <base>
tag which makes all relative URLs in the document relative to this base. You could make use of it. Put it in the <h:head>
.
<base href="#{request.requestURL.substring(0, request.requestURL.length() - request.requestURI.length())}#{request.contextPath}/" />
...
<li><a href="index.xhtml">Home</a></li>
<li><a href="about_us.xhtml">About us</a></li>
(note: this requires EL 2.2, otherwise you'd better use JSTL fn:substring()
, see also this answer)
This should end up in the generated HTML something like as
<base href="http://example.com/webname/" />
Note that the <base>
tag has a caveat: it makes all jump anchors in the page like <a href="#top">
relative to it as well! See also Is it recommended to use the <base> html tag? In JSF you could solve it like <a href="#{request.requestURI}#top">top</a>
or <h:link value="top" fragment="top" />
.
You could do this:
import re
import string
set1={'Apple.good','Orange.good','Pear.bad','Pear.good','Banana.bad','Potato.bad'}
for x in set1:
x.replace('.good',' ')
x.replace('.bad',' ')
x = re.sub('\.good$', '', x)
x = re.sub('\.bad$', '', x)
print(x)
Maybe you forgot to change the permissions of app/cache app/log
I'm using Ubuntu so
sudo chmod -R 777 app/cache
sudo chmod -R 777 app/logs
sudo setfacl -dR -m u::rwX app/cache app/logs
Hope it helps..
I got the same error.
On my view I was overriding get_form_kwargs() like this:
class UserAccountView(FormView):
form_class = UserAccountForm
success_url = '/'
template_name = 'user_account/user-account.html'
def get_form_kwargs(self):
kwargs = super(UserAccountView, self).get_form_kwargs()
kwargs.update({'user': self.request.user})
return kwargs
But on my form I failed to override the init() method. Once I did it. Problem solved
class UserAccountForm(forms.Form):
first_name = forms.CharField(label='Your first name', max_length=30)
last_name = forms.CharField(label='Your last name', max_length=30)
email = forms.EmailField(max_length=75)
def __init__(self, *args, **kwargs):
user = kwargs.pop('user')
super(UserAccountForm, self).__init__(*args, **kwargs)
The code below works for trusting self-signed certificates. You have to use the TrustSelfSignedStrategy when creating your client:
SSLContextBuilder builder = new SSLContextBuilder();
builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
builder.build());
CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
sslsf).build();
HttpGet httpGet = new HttpGet("https://some-server");
CloseableHttpResponse response = httpclient.execute(httpGet);
try {
System.out.println(response.getStatusLine());
HttpEntity entity = response.getEntity();
EntityUtils.consume(entity);
} finally {
response.close();
}
I did not include the SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER
on purpose: The point was to allow testing with self signed certificates so you don't have to acquire a proper certificate from a certification authority. You can easily create a self-signed certificate with the correct host name, so do that instead of adding the SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER
flag.
You can get other constructors with getConstructor(...).
As per this post:
end((explode('-', $string)));
which won't cause E_STRICT warning in PHP 5 (PHP magic). Although the warning will be issued in PHP 7, so adding @
in front of it can be used as a workaround.
The syntax of set item is
localStorage.setItem(key,value);
The syntax of get item is
localStorage.getItem(key);
An example of this is:
localStorage.setItem('email','[email protected]');
let mail = localStorage.getItem("email");
if(mail){
console.log('your email id is', mail);
}
}
Your not applying Date formator. rather you are just parsing the date. to get output in this format
yyyy-MM-dd HH:mm:ss.SSSSSS
we have to use format() method here is full example:-
Here is full example:-
it will take Date in this format yyyy-MM-dd HH:mm:ss.SSSSSS
and as result we will get output as same as this format yyyy-MM-dd HH:mm:ss.SSSSSS
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
//TODO OutPut should LIKE in this format yyyy-MM-dd HH:mm:ss.SSSSSS.
public class TestDateExample {
public static void main(String args[]) throws ParseException {
SimpleDateFormat changeFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSSSSS");
java.util.Date temp = changeFormat.parse("2012-07-10 14:58:00.000000");
Date thisDate = changeFormat.parse("2012-07-10 14:58:00.000000");
System.out.println(thisDate);
System.out.println("----------------------------");
System.out.println("After applying formating :");
String strDateOutput = changeFormat.format(temp);
System.out.println(strDateOutput);
}
}
Consolodating other answers, per Joel, and hopefully improving slightly as I go:
You can do this with Regex.Replace()
:
string s = Regex.Replace (
" 1 2 4 5",
@"[ ]{2,}",
" "
);
Or with String.Split()
:
static class StringExtensions
{
public static string Join(this IList<string> value, string separator)
{
return string.Join(separator, value.ToArray());
}
}
//...
string s = " 1 2 4 5".Split (
" ".ToCharArray(),
StringSplitOptions.RemoveEmptyEntries
).Join (" ");
Params contains the following three groups of parameters:
match '/user/:id'
in routes.rb will set params[:id]params[:controller]
and params[:action]
is always available and contains the current controller and actionWith Lodash you can create a template and you can do that following way:
<div class="container">
<div class="row justify-content-center">
<div class="col-12">
<table id="tblEntAttributes" class="table">
<tbody>
<tr>
<td>
chkboxId
</td>
<td>
chkboxValue
</td>
<td>
displayName
</td>
<td>
logicalName
</td>
<td>
dataType
</td>
</tr>
</tbody>
</table>
<button class="btn btn-primary" id="test">appendTo</button>
</div>
</div>
</div>
And here goes the javascript:
var count = 1;
window.addEventListener('load', function () {
var compiledRow = _.template("<tr><td><input type=\"checkbox\" id=\"<%= chkboxId %>\" value=\"<%= chkboxValue %>\"></td><td><%= displayName %></td><td><%= logicalName %></td><td><%= dataType %></td><td><input type=\"checkbox\" id=\"chkAllPrimaryAttrs\" name=\"chkAllPrimaryAttrs\" value=\"chkAllPrimaryAttrs\"></td><td><input type=\"checkbox\" id=\"chkAllPrimaryAttrs\" name=\"chkAllPrimaryAttrs\" value=\"chkAllPrimaryAttrs\"></td></tr>");
document.getElementById('test').addEventListener('click', function (e) {
var ajaxData = { 'chkboxId': 'chkboxId-' + count, 'chkboxValue': 'chkboxValue-' + count, 'displayName': 'displayName-' + count, 'logicalName': 'logicalName-' + count, 'dataType': 'dataType-' + count };
var tableRowData = compiledRow(ajaxData);
$("#tblEntAttributes tbody").append(tableRowData);
count++;
});

Sometimes You just open too much applications in Windows and make the gradle have no enough memory to start the daemon process.So when you come across with this situation,you can just close some applications such as Chrome and so on. Then restart your android studio.
Your first problem is that you are passing -3 to the 2nd parameter of Columns.Add. It needs to be -2 for it to auto-size the column. Source: http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.columns.aspx (look at the comments on the code example at the bottom)
private void initListView()
{
// Add columns
lvRegAnimals.Columns.Add("Id", -2,HorizontalAlignment.Left);
lvRegAnimals.Columns.Add("Name", -2, HorizontalAlignment.Left);
lvRegAnimals.Columns.Add("Age", -2, HorizontalAlignment.Left);
}
You can also use the other overload, Add(string). E.g:
lvRegAnimals.Columns.Add("Id");
lvRegAnimals.Columns.Add("Name");
lvRegAnimals.Columns.Add("Age");
Reference for more overloads: http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.columnheadercollection.aspx
Second, to add items to the ListView, you need to create instances of ListViewItem and add them to the listView's Items collection. You will need to use the string[] constructor.
var item1 = new ListViewItem(new[] {"id123", "Tom", "24"});
var item2 = new ListViewItem(new[] {person.Id, person.Name, person.Age});
lvRegAnimals.Items.Add(item1);
lvRegAnimals.Items.Add(item2);
You can also store objects in the item's Tag property.
item2.Tag = person;
And then you can extract it
var person = item2.Tag as Person;
Let me know if you have any questions and I hope this helps!
Makefile.am
is a programmer-defined file and is used by automake
to generate the Makefile.in
file (the .am
stands for automake).
The configure
script typically seen in source tarballs will use the Makefile.in
to generate a Makefile
.
The configure
script itself is generated from a programmer-defined file named either configure.ac
or configure.in
(deprecated). I prefer .ac
(for autoconf) since it differentiates it from the generated Makefile.in
files and that way I can have rules such as make dist-clean
which runs rm -f *.in
. Since it is a generated file, it is not typically stored in a revision system such as Git, SVN, Mercurial or CVS, rather the .ac
file would be.
Read more on GNU Autotools.
Read about make
and Makefile
first, then learn about automake
, autoconf
, libtool
, etc.
This is discouraged (if you want to create/distribute a clean Docker image), since the PATH
variable is set by /etc/profile
script, the value can be overridden.
head /etc/profile
:
if [ "`id -u`" -eq 0 ]; then
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games"
fi
export PATH
At the end of the Dockerfile, you could add:
RUN echo "export PATH=$PATH" > /etc/environment
So PATH is set for all users.
If your MySQL server runs on default settings, you don't need to specify that.
Default MySQL port is 3306.
[updated to show mysql_error() usage]
$conn = mysql_connect($dbhost, $dbuser, $dbpass)
or die('Error connecting to mysql: '.mysql_error());
On dynamic cells, rowHeight
set on the UITableView always overrides the individual cells' rowHeight.
But on static cells, rowHeight
set on individual cells can override UITableView's.
Not sure if it's a bug, Apple might be intentionally doing this?
If the aforementioned answers don't help then check whether the backend server is up and running or not as in my case the server crashed and this error turns out to be totally misleading.
The command you have typed is /startup.sh
, if you have to start a shell script you have to fire the command as shown below:
$ cd /home/mpatil/softwares/apache-tomcat-7.0.47/bin
$ sh startup.sh
or
$ ./startup.sh
Please try that, you also have to go to your tomcat's bin-folder (by using the cd-command) to execute this shell script. In your case this is /home/mpatil/softwares/apache-tomcat-7.0.47/bin
.

This can be solved with an assignment tag:

Starting in pandas 0.24 you can simplify this with the mode
keyword argument of ExcelWriter

import pandas as pd
with pd.ExcelWriter('the_file.xlsx', engine='openpyxl', mode='a') as writer:

This is still the top post when searching, but it's no longer valid. Best answer is here, but the TLDR is
<c-b>:resize-window -A
Best way to find out is to record the macro and perform the exact steps and see what VBA code it generates. you can then go and replace the bits you want to make generic (i.e. file names and stuff)
Another quick and simple option...
import os
os.system('start path/to/player/executable path/to/file.mp3')
Now you might need to make some slight changes to make it work. For example, if the player needs extra arguments or you don't need to specify the full path. But this is a simple way of doing it.

Our team had the same need with a remote SSH-executed script which was timing out after 25 minutes of inactivity. Here is a solution with the monitoring loop checking the background process every second, but printing only every 10 minutes to suppress an inactivity timeout.
long_running.sh &
pid=$!
# Wait on a background job completion. Query status every 10 minutes.
declare -i elapsed=0
# `ps -p ${pid}` works on macOS and CentOS. On both OSes `ps ${pid}` works as well.
while ps -p ${pid} >/dev/null; do
sleep 1
if ((++elapsed % 600 == 0)); then
echo "Waiting for the completion of the main script. $((elapsed / 60))m and counting ..."
fi
done
# Return the exit code of the terminated background process. This works in Bash 4.4 despite what Bash docs say:
# "If neither jobspec nor pid specifies an active child process of the shell, the return status is 127."
wait ${pid}
Just for clarification: setRequestProperty("User-Agent", "Mozilla ...")
now works just fine and doesn't append java/xx
at the end! At least with Java 1.6.30 and newer.
I listened on my machine with netcat(a port listener):
$ nc -l -p 8080
It simply listens on the port, so you see anything which gets requested, like raw http-headers.
And got the following http-headers without setRequestProperty:
GET /foobar HTTP/1.1
User-Agent: Java/1.6.0_30
Host: localhost:8080
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive
And WITH setRequestProperty:
GET /foobar HTTP/1.1
User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2
Host: localhost:8080
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive
As you can see the user agent was properly set.
Full example:
import java.io.IOException;
import java.net.URL;
import java.net.URLConnection;
public class TestUrlOpener {
public static void main(String[] args) throws IOException {
URL url = new URL("http://localhost:8080/foobar");
URLConnection hc = url.openConnection();
hc.setRequestProperty("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2");
System.out.println(hc.getContentType());
}
}
You can check it from your command prompt by running gem help commands
and then selecting the proper command:
kirti@kirti-Aspire-5733Z:~$ gem help commands
GEM commands are:
build Build a gem from a gemspec
cert Manage RubyGems certificates and signing settings
check Check a gem repository for added or missing files
cleanup Clean up old versions of installed gems in the local
repository
contents Display the contents of the installed gems
dependency Show the dependencies of an installed gem
environment Display information about the RubyGems environment
fetch Download a gem and place it in the current directory
generate_index Generates the index files for a gem server directory
help Provide help on the 'gem' command
install Install a gem into the local repository
list Display gems whose name starts with STRING
lock Generate a lockdown list of gems
mirror Mirror all gem files (requires rubygems-mirror)
outdated Display all gems that need updates
owner Manage gem owners on RubyGems.org.
pristine Restores installed gems to pristine condition from
files located in the gem cache
push Push a gem up to RubyGems.org
query Query gem information in local or remote repositories
rdoc Generates RDoc for pre-installed gems
regenerate_binstubs Re run generation of executable wrappers for gems.
search Display all gems whose name contains STRING
server Documentation and gem repository HTTP server
sources Manage the sources and cache file RubyGems uses to
search for gems
specification Display gem specification (in yaml)
stale List gems along with access times
uninstall Uninstall gems from the local repository
unpack Unpack an installed gem to the current directory
update Update installed gems to the latest version
which Find the location of a library file you can require
yank Remove a specific gem version release from
RubyGems.org
For help on a particular command, use 'gem help COMMAND'.
Commands may be abbreviated, so long as they are unambiguous.
e.g. 'gem i rake' is short for 'gem install rake'.
kirti@kirti-Aspire-5733Z:~$
Now from the above I can see the command environment
is helpful. So I would do:
kirti@kirti-Aspire-5733Z:~$ gem help environment
Usage: gem environment [arg] [options]
Common Options:
-h, --help Get help on this command
-V, --[no-]verbose Set the verbose level of output
-q, --quiet Silence commands
--config-file FILE Use this config file instead of default
--backtrace Show stack backtrace on errors
--debug Turn on Ruby debugging
Arguments:
packageversion display the package version
gemdir display the path where gems are installed
gempath display path used to search for gems
version display the gem format version
remotesources display the remote gem servers
platform display the supported gem platforms
<omitted> display everything
Summary:
Display information about the RubyGems environment
Description:
The RubyGems environment can be controlled through command line arguments,
gemrc files, environment variables and built-in defaults.
Command line argument defaults and some RubyGems defaults can be set in a
~/.gemrc file for individual users and a /etc/gemrc for all users. These
files are YAML files with the following YAML keys:
:sources: A YAML array of remote gem repositories to install gems from
:verbose: Verbosity of the gem command. false, true, and :really are the
levels
:update_sources: Enable/disable automatic updating of repository metadata
:backtrace: Print backtrace when RubyGems encounters an error
:gempath: The paths in which to look for gems
:disable_default_gem_server: Force specification of gem server host on
push
<gem_command>: A string containing arguments for the specified gem command
Example:
:verbose: false
install: --no-wrappers
update: --no-wrappers
:disable_default_gem_server: true
RubyGems' default local repository can be overridden with the GEM_PATH and
GEM_HOME environment variables. GEM_HOME sets the default repository to
install into. GEM_PATH allows multiple local repositories to be searched for
gems.
If you are behind a proxy server, RubyGems uses the HTTP_PROXY,
HTTP_PROXY_USER and HTTP_PROXY_PASS environment variables to discover the
proxy server.
If you would like to push gems to a private gem server the RUBYGEMS_HOST
environment variable can be set to the URI for that server.
If you are packaging RubyGems all of RubyGems' defaults are in
lib/rubygems/defaults.rb. You may override these in
lib/rubygems/defaults/operating_system.rb
kirti@kirti-Aspire-5733Z:~$
Finally to show you what you asked, I would do:
kirti@kirti-Aspire-5733Z:~$ gem environment gemdir
/home/kirti/.rvm/gems/ruby-2.0.0-p0
kirti@kirti-Aspire-5733Z:~$ gem environment gempath
/home/kirti/.rvm/gems/ruby-2.0.0-p0:/home/kirti/.rvm/gems/ruby-2.0.0-p0@global
kirti@kirti-Aspire-5733Z:~$
You can also use a while loop:
while (true) {
//your code
}
Things become complicated when you want to post files via multipart/form-data
, especially multiple binary files. Below is a working example:
const FormData = require('form-data')
const fs = require('fs')
const path = require('path')
const formData = new FormData()
formData.append('files[]', JSON.stringify({ to: [{ phoneNumber: process.env.RINGCENTRAL_RECEIVER }] }), 'test.json')
formData.append('files[]', fs.createReadStream(path.join(__dirname, 'test.png')), 'test.png')
await rc.post('/restapi/v1.0/account/~/extension/~/fax', formData, {
headers: formData.getHeaders()
})
headers: {'Content-Type': 'multipart/form-data' }
I prefer headers: formData.getHeaders()
async
and await
above, you can change them to plain Promise statements if you don't like themheaders: { ...yourHeaders, ...formData.getHeaders() }
Newly added content below:
Browser's FormData
is different from the NPM package 'form-data'. The following code works for me in browser:
HTML:
<input type="file" id="image" accept="image/png"/>
JavaScript:
const formData = new FormData()
// add a non-binary file
formData.append('files[]', new Blob(['{"hello": "world"}'], { type: 'application/json' }), 'request.json')
// add a binary file
const element = document.getElementById('image')
const file = element.files[0]
formData.append('files[]', file, file.name)
await rc.post('/restapi/v1.0/account/~/extension/~/fax', formData)
I've been going back and forth on these two options the last few times I've needed them. Up until recently, my preference has been for the sealed trait/case object option.
1) Scala Enumeration Declaration
object OutboundMarketMakerEntryPointType extends Enumeration {
type OutboundMarketMakerEntryPointType = Value
val Alpha, Beta = Value
}
2) Sealed Traits + Case Objects
sealed trait OutboundMarketMakerEntryPointType
case object AlphaEntryPoint extends OutboundMarketMakerEntryPointType
case object BetaEntryPoint extends OutboundMarketMakerEntryPointType
While neither of these really meet all of what a java enumeration gives you, below are the pros and cons:
Scala Enumeration
Pros: -Functions for instantiating with option or directly assuming accurate (easier when loading from a persistent store) -Iteration over all possible values is supported
Cons: -Compilation warning for non-exhaustive search is not supported (makes pattern matching less ideal)
Case Objects/Sealed traits
Pros: -Using sealed traits, we can pre-instantiate some values while others can be injected at creation time -full support for pattern matching (apply/unapply methods defined)
Cons: -Instantiating from a persistent store - you often have to use pattern matching here or define your own list of all possible 'enum values'
What ultimately made me change my opinion was something like the following snippet:
object DbInstrumentQueries {
def instrumentExtractor(tableAlias: String = "s")(rs: ResultSet): Instrument = {
val symbol = rs.getString(tableAlias + ".name")
val quoteCurrency = rs.getString(tableAlias + ".quote_currency")
val fixRepresentation = rs.getString(tableAlias + ".fix_representation")
val pointsValue = rs.getInt(tableAlias + ".points_value")
val instrumentType = InstrumentType.fromString(rs.getString(tableAlias +".instrument_type"))
val productType = ProductType.fromString(rs.getString(tableAlias + ".product_type"))
Instrument(symbol, fixRepresentation, quoteCurrency, pointsValue, instrumentType, productType)
}
}
object InstrumentType {
def fromString(instrumentType: String): InstrumentType = Seq(CurrencyPair, Metal, CFD)
.find(_.toString == instrumentType).get
}
object ProductType {
def fromString(productType: String): ProductType = Seq(Commodity, Currency, Index)
.find(_.toString == productType).get
}
The .get
calls were hideous - using enumeration instead I can simply call the withName method on the enumeration as follows:
object DbInstrumentQueries {
def instrumentExtractor(tableAlias: String = "s")(rs: ResultSet): Instrument = {
val symbol = rs.getString(tableAlias + ".name")
val quoteCurrency = rs.getString(tableAlias + ".quote_currency")
val fixRepresentation = rs.getString(tableAlias + ".fix_representation")
val pointsValue = rs.getInt(tableAlias + ".points_value")
val instrumentType = InstrumentType.withNameString(rs.getString(tableAlias + ".instrument_type"))
val productType = ProductType.withName(rs.getString(tableAlias + ".product_type"))
Instrument(symbol, fixRepresentation, quoteCurrency, pointsValue, instrumentType, productType)
}
}
So I think my preference going forward is to use Enumerations when the values are intended to be accessed from a repository and case objects/sealed traits otherwise.
In PostGIS, for points with latitude and longitude there is geography datatype.
To add a column:
alter table your_table add column geog geography;
To insert data:
insert into your_table (geog) values ('SRID=4326;POINT(longitude latitude)');
4326 is Spatial Reference ID that says it's data in degrees longitude and latitude, same as in GPS. More about it: http://epsg.io/4326
Order is Longitude, Latitude - so if you plot it as the map, it is (x, y).
To find closest point you need first to create spatial index:
create index on your_table using gist (geog);
and then request, say, 5 closest to a given point:
select *
from your_table
order by geog <-> 'SRID=4326;POINT(lon lat)'
limit 5;
Alternatively YUI has http://yuilibrary.com/yui/docs/api/classes/QueryString.html#method_stringify.
For example:
var data = { one: 'first', two: 'second' };
var result = Y.QueryString.stringify(data);
if you want to save the selection to file or any else and call it later, here what I do
string[] lines = new string[1];
lines[0] = groupBoxTes.Controls.OfType<RadioButton>()
.FirstOrDefault(r => r.Checked).Text;
File.WriteAllLines("Config.ini", lines);
then call it with
string[] ini = File.ReadAllLines("Config.ini");
groupBoxTes.Controls.OfType<RadioButton>()
.FirstOrDefault(r => (r.Text == ini[0])).Checked = true;
I figured it out. The below works in converting it to a 24 hr date format.
select date_parse('7/22/2016 6:05:04 PM','%m/%d/%Y %h:%i:%s %p')
If you can change the order of the elements:
int[] myArray = new int[]{1, 3, 8, 5, 7, };
Arrays.sort(myArray);
int max = myArray[myArray.length - 1];
If you can't change the order of the elements:
int[] myArray = new int[]{1, 3, 8, 5, 7, };
int max = Integer.MIN_VALUE;
for(int i = 0; i < myArray.length; i++) {
if(myArray[i] > max) {
max = myArray[i];
}
}
I have always used the following:
If Request.QueryString("MyQueryString") IsNot Nothing Then
But only because syntactically it reads better.
When testing for a valid QueryString entry I also use the following:
If Not String.IsNullOrEmpty(Request.QueryString("MyQueryString")) Then
These are just the methods I have always used so I could not justify their usage other than they make the most sense to me when reading back code.
What would help, except for excluding, is modular dependencies.
With one flat classloading (standalone app), or semi-hierarchical (JBoss AS/EAP 5.x) this was a problem.
But with modular frameworks like OSGi and JBoss Modules, this is not so much pain anymore. The libraries may use whichever library they want, independently.
Of course, it's still most recommendable to stick with just a single implementation and version, but if there's no other way (using extra features from more libs), then modularizing might save you.
A good example of JBoss Modules in action is, naturally, JBoss AS 7 / EAP 6 / WildFly 8, for which it was primarily developed.
Example module definition:
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.jboss.msc">
<main-class name="org.jboss.msc.Version"/>
<properties>
<property name="my.property" value="foo"/>
</properties>
<resources>
<resource-root path="jboss-msc-1.0.1.GA.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="org.jboss.logging"/>
<module name="org.jboss.modules"/>
<!-- Optional deps -->
<module name="javax.inject.api" optional="true"/>
<module name="org.jboss.threads" optional="true"/>
</dependencies>
</module>
In comparison with OSGi, JBoss Modules is simpler and faster. While missing certain features, it's sufficient for most projects which are (mostly) under control of one vendor, and allow stunning fast boot (due to paralelized dependencies resolving).
Note that there's a modularization effort underway for Java 8, but AFAIK that's primarily to modularize the JRE itself, not sure whether it will be applicable to apps.
It seems that the latest function for this in windows 7 is robocopy.
Usage example:
robocopy <source> <destination> /e /xf <file to exclude> <another file>
/e copies subdirectories including empty ones, /xf excludes certain files from being copied.
More options here: http://technet.microsoft.com/en-us/library/cc733145(v=ws.10).aspx
In Java 8 it can be done with:
String s = "edcba".chars()
.sorted()
.collect(StringBuilder::new, StringBuilder::appendCodePoint, StringBuilder::append)
.toString();
A slightly shorter alternative that works with a Stream of Strings of length one (each character in the unsorted String is converted into a String in the Stream) is:
String sorted =
Stream.of("edcba".split(""))
.sorted()
.collect(Collectors.joining());
For me, line numbers wouldn't appear in the editor until I added the option under both the "all languages" pane, and the language I was working under (C# etc)... screen capture showing editor options
In my opinion, varchar(n)
has it's own advantages. Yes, they all use the same underlying type and all that. But, it should be pointed out that indexes in PostgreSQL has its size limit of 2712 bytes per row.
TL;DR:
If you use text
type without a constraint and have indexes on these columns, it is very possible that you hit this limit for some of your columns and get error when you try to insert data but with using varchar(n)
, you can prevent it.
Some more details: The problem here is that PostgreSQL doesn't give any exceptions when creating indexes for text
type or varchar(n)
where n
is greater than 2712. However, it will give error when a record with compressed size of greater than 2712 is tried to be inserted. It means that you can insert 100.000 character of string which is composed by repetitive characters easily because it will be compressed far below 2712 but you may not be able to insert some string with 4000 characters because the compressed size is greater than 2712 bytes. Using varchar(n)
where n
is not too much greater than 2712, you're safe from these errors.
To convert a DateTime
to a TimeSpan
you should choose a base date/time - e.g. midnight of January 1st, 2000, and subtract it from your DateTime
value (and add it when you want to convert back to DateTime
).
If you simply want to convert a DateTime
to a number you can use the Ticks
property.
Here is a codepen that I wrote for the Mandelbrot fractal using plain javascript and HTML.
Hopefully it is easy to understand the code.
The most complicated part is scale and translate the coordinate systems. Also complicated is making the rainbow palette.
function mandel(x,y) {
var a=0; var b=0;
for (i = 0; i<250; ++i) {
// Complex z = z^2 + c
var t = a*a - b*b;
b = 2*a*b;
a = t;
a = a + x;
b = b + y;
var m = a*a + b*b;
if (m > 10) return i;
}
return 250;
}
Here's a very simple way to do it;
int main()
{
int s=7,l=1;
vector <bool> v;
v.clear();
while (l <= 4)
{
v.push_back(s%2);
s /= 2;
l++;
}
for (l=(v.size()-1); l >= 0; l--)
{
cout<<v[l]<<" ";
}
return 0;
}
when you set the density to 96, doesn't it look good?
when i tried it i saw that saving as jpg resulted with better quality, but larger file size
Try:
SELECT neededfield, CONCAT(firstname, ' ', lastname) as firstlast
FROM users
WHERE CONCAT(firstname, ' ', lastname) = "Bob Michael Jones"
Your alias firstlast is not available in the where clause of the query unless you do the query as a sub-select.
Consider Android Development:

Library: android.app.Activity library (Class with all code)
API: Interface basically all functions with which we call
SDK: The Android SDK provides you the API libraries and developer tools necessary to build, test, and debug apps for Android (----tools - DDMS,Emulator ----platforms - Android OS versions, ----platform-tools - ADB, ----API docs)
ToolKit: Could be ADT Bundle
Framework: Big library but more of architecture-oriented

There is a rumor that Apple engineers claimed, to make this performant they are reading directly out of the gpu buffer which raises security issues which is why there is no public API to do this yet.
I think that it really depends on your personal coding style. If you're used to C++, Javascript, etc., you might feel more comfortable using the {} syntax. If you're used to Visual Basic, you might want to use the if : endif; syntax.
I'm not sure one can definitively say one is easier to read than the other - it's personal preference. I usually do something like this:
<?php
if ($foo) { ?>
<p>Foo!</p><?php
} else { ?>
<p>Bar!</p><?php
} // if-else ($foo) ?>
Whether that's easier to read than:
<?php
if ($foo): ?>
<p>Foo!</p><?php
else: ?>
<p>Bar!</p><?php
endif; ?>
is a matter of opinion. I can see why some would feel the 2nd way is easier - but only if you haven't been programming in Javascript and C++ all your life. :)
Finally got this error to go away on a restore. I moved to SQL2012 out of frustration, but I guess this would probably still work on 2008R2. I had to use the logical names:

FROM DISK = ‘location of your.bak file’
And from there I ran a restore statement with MOVE
using logical names.
RESTORE DATABASE database1
FROM DISK = '\\database path\database.bak'
WITH
MOVE 'File_Data' TO 'E:\location\database.mdf',
MOVE 'File_DOCS' TO 'E:\location\database_1.ndf',
MOVE 'file' TO 'E:\location\database_2.ndf',
MOVE 'file' TO 'E:\location\database_3.ndf',
MOVE 'file_Log' TO 'E:\location\database.ldf'
When it was done restoring, I almost wept with joy.
Good luck!
Make the value a list, e.g.
a["abc"] = [1, 2, "bob"]
UPDATE:
There are a couple of ways to add values to key, and to create a list if one isn't already there. I'll show one such method in little steps.
key = "somekey"
a.setdefault(key, [])
a[key].append(1)
Results:
>>> a
{'somekey': [1]}
Next, try:
key = "somekey"
a.setdefault(key, [])
a[key].append(2)
Results:
>>> a
{'somekey': [1, 2]}
The magic of setdefault
is that it initializes the value for that key if that key is not defined, otherwise it does nothing. Now, noting that setdefault
returns the key you can combine these into a single line:
a.setdefault("somekey",[]).append("bob")
Results:
>>> a
{'somekey': [1, 2, 'bob']}
You should look at the dict
methods, in particular the get()
method, and do some experiments to get comfortable with this.
template<class It>
std::reverse_iterator<It> reversed( It it ) {
return std::reverse_iterator<It>(std::forward<It>(it));
}
Then:
for( auto rit = reversed(data.end()); rit != reversed(data.begin()); ++rit ) {
std::cout << *rit;
Alternatively in C++14 just do:
for( auto rit = std::rbegin(data); rit != std::rend(data); ++rit ) {
std::cout << *rit;
In C++03/11 most standard containers have a .rbegin()
and .rend()
method as well.
Finally, you can write the range adapter backwards
as follows:
namespace adl_aux {
using std::begin; using std::end;
template<class C>
decltype( begin( std::declval<C>() ) ) adl_begin( C&& c ) {
return begin(std::forward<C>(c));
}
template<class C>
decltype( end( std::declval<C>() ) ) adl_end( C&& c ) {
return end(std::forward<C>(c));
}
}
template<class It>
struct simple_range {
It b_, e_;
simple_range():b_(),e_(){}
It begin() const { return b_; }
It end() const { return e_; }
simple_range( It b, It e ):b_(b), e_(e) {}
template<class OtherRange>
simple_range( OtherRange&& o ):
simple_range(adl_aux::adl_begin(o), adl_aux::adl_end(o))
{}
// explicit defaults:
simple_range( simple_range const& o ) = default;
simple_range( simple_range && o ) = default;
simple_range& operator=( simple_range const& o ) = default;
simple_range& operator=( simple_range && o ) = default;
};
template<class C>
simple_range< decltype( reversed( adl_aux::adl_begin( std::declval<C&>() ) ) ) >
backwards( C&& c ) {
return { reversed( adl_aux::adl_end(c) ), reversed( adl_aux::adl_begin(c) ) };
}
and now you can do this:
for (auto&& x : backwards(ctnr))
std::cout << x;
which I think is quite pretty.
you never set d[a]
to any value.
Because of this, d[a]
evaluates to undefined
, and you can't set properties on undefined
.
If you add d[a] = {}
right after d = {}
things should work as expected.
Alternatively, you could use an object initializer:
d[a] = {
greetings: b,
data: c
};
Or you could set all the properties of d
in an anonymous function instance:
d = new function () {
this[a] = {
greetings: b,
data: c
};
};
If you're in an environment that supports ES2015 features, you can use computed property names:
d = {
[a]: {
greetings: b,
data: c
}
};
In all versions of MySQL, simply alias the aggregate in the SELECT list, and order by the alias:
SELECT COUNT(id) AS theCount, `Tag` from `images-tags`
GROUP BY `Tag`
ORDER BY theCount DESC
LIMIT 20
Security researchers Jean-Baptiste Bédrune and Jean Sigwald presented how to do this at Hack-in-the-box Amsterdam 2011.
Since then, Apple has released an iOS Security Whitepaper with more details about keys and algorithms, and Charlie Miller et al. have released the iOS Hacker’s Handbook, which covers some of the same ground in a how-to fashion. When iOS 10 first came out there were changes to the backup format which Apple did not publicize at first, but various people reverse-engineered the format changes.
The great thing about encrypted iPhone backups is that they contain things like WiFi passwords that aren’t in regular unencrypted backups. As discussed in the iOS Security Whitepaper, encrypted backups are considered more “secure,” so Apple considers it ok to include more sensitive information in them.
An important warning: obviously, decrypting your iOS device’s backup
removes its encryption. To protect your privacy and security, you should
only run these scripts on a machine with full-disk encryption. While it
is possible for a security expert to write software that protects keys in
memory, e.g. by using functions like VirtualLock()
and
SecureZeroMemory()
among many other things, these
Python scripts will store your encryption keys and passwords in strings to
be garbage-collected by Python. This means your secret keys and passwords
will live in RAM for a while, from whence they will leak into your swap
file and onto your disk, where an adversary can recover them. This
completely defeats the point of having an encrypted backup.
The iOS Security Whitepaper explains the fundamental concepts of per-file keys, protection classes, protection class keys, and keybags better than I can. If you’re not already familiar with these, take a few minutes to read the relevant parts.
Now you know that every file in iOS is encrypted with its own random per-file encryption key, belongs to a protection class, and the per-file encryption keys are stored in the filesystem metadata, wrapped in the protection class key.
To decrypt:
Decode the keybag stored in the BackupKeyBag
entry of
Manifest.plist
. A high-level overview of this structure is given in
the whitepaper. The iPhone Wiki
describes the binary format: a 4-byte string type field, a 4-byte
big-endian length field, and then the value itself.
The important values are the PBKDF2 ITER
ations and SALT
, the double
protection salt DPSL
and iteration count DPIC
, and then for each
protection CLS
, the WPKY
wrapped key.
Using the backup password derive a 32-byte key using the correct PBKDF2
salt and number of iterations. First use a SHA256 round with DPSL
and
DPIC
, then a SHA1 round with ITER
and SALT
.
Unwrap each wrapped key according to RFC 3394.
Decrypt the manifest database by pulling the 4-byte protection class and longer key from the ManifestKey
in Manifest.plist
, and unwrapping it. You now have a
SQLite database with all file metadata.
For each file of interest, get the class-encrypted per-file encryption
key and protection class code by looking in the Files.file
database
column for a binary plist containing EncryptionKey
and
ProtectionClass
entries. Strip the initial four-byte length tag from
EncryptionKey
before using.
Then, derive the final decryption key by unwrapping it with the class key that was unwrapped with the backup password. Then decrypt the file using AES in CBC mode with a zero IV.
First you’ll need some library dependencies. If you’re on a mac using a homebrew-installed Python 2.7 or 3.7, you can install the dependencies with:
CFLAGS="-I$(brew --prefix)/opt/openssl/include" \
LDFLAGS="-L$(brew --prefix)/opt/openssl/lib" \
pip install biplist fastpbkdf2 pycrypto
In runnable source code form, here is how to decrypt a single preferences file from an encrypted iPhone backup:

The iphone-dataprotection code posted by Bédrune and Sigwald can decrypt the keychain from a backup, including fun things like saved wifi and website passwords:
$ python iphone-dataprotection/python_scripts/keychain_tool.py ...

| Passwords |
--------------------------------------------------------------------------------------
|Service |Account |Data |Access group |Protection class|
--------------------------------------------------------------------------------------
|AirPort |Ed’s Coffee Shop |<3FrenchRoast |apple |AfterFirstUnlock|
...
That code no longer works on backups from phones using the latest iOS, but there are some golang ports that have been kept up to date allowing access to the keychain.
It looks like the ~ gives the functionality that I need, but I am yet to find any appropriate documentation on it.
df.filter(~col('bar').isin(['a','b'])).show()

I had the same problem as Andre. There does not seem to be a direct solution, but a CAST in the query that generates the data fixes the problem as long as you can live within the restrictions of SMALLDATETIME. In the following query, the first column does not format correctly in Excel, the second does.
SELECT GETDATE(), CAST(GETDATE() AS SMALLDATETIME)
Perhaps the fractional part of the seconds in DATETIME and DATETIME2 confuses Excel.
Since you're using jQuery, stop binding event handlers in your HTML, and start writing unobtrusive JavaScript.
$(document).ready(function ()
{
function myfunction(me)
{
$(me).fancybox({
'autoScale': true,
'transitionIn': 'elastic',
'transitionOut': 'elastic',
'speedIn': 500,
'speedOut': 300,
'autoDimensions': true,
'centerOnScroll': true // remove the trailing comma!!
}).click();
// fire the click event after initializing fancybox on this element
// this should open the fancybox
}
// use .one() so that the handler is executed at most once per element
$('a[href=#modalMine]').one('click', function ()
{
myfunction(this);
return false;
});
});
However, I don't particularly see a reason for setting up the fancybox on click. You could just do this instead:
$(document).ready(function ()
{
function myfunction()
{
// note the use of "this" rather than a function argument
$(this).fancybox({
'autoScale': true,
'transitionIn': 'elastic',
'transitionOut': 'elastic',
'speedIn': 500,
'speedOut': 300,
'autoDimensions': true,
'centerOnScroll': true
});
}
$('a[href=#modalMine]').each(myfunction);
});
This should do what you want:
$("#iframe").ready(function() {
var body = $("#iframe").contents().find("body");
body.append('Test');
});
Check this JSFiddle for working demo.
Edit: You can of course do it one line style:
$("#iframe").contents().find("body").append('Test');
d = {}
for i in keys:
d[i] = None
This works for me:
$ pip install -r requirements.txt --no-index --find-links file:///tmp/packages
--no-index
- Ignore package index (only looking at --find-links
URLs instead).
-f, --find-links <URL>
- If a URL or path to an HTML file, then parse for links to archives.
If a local path or file://
URL that's a directory, then look for archives in the directory listing.
Package works fine on Friday, check in to TFS and go home. Open it on Monday, getting errors everywhere. "connection manager variable $project._connectionstring was not found in the variables collection".
I rtclick-edit the connection and test connectivity, works no prob;em. The ConnMnger is in the Connection Managers list in the solution. When open the TARGET object connected to this connection manager, and click on MAPPINGS, the error above pops up. There is no reference to connection manager variables anywhere in the mapping.
Turns out, to correct this you must right click on the connection manager in the Connection Manager window and choose PARAMETERIZE. Fill in the options as necessar -
PROPERTY: ConnectionString Use Exisgint Parameter: $Project::ConnMgrName_ConnectionString OR Create New PArameter: follow the options
Once this connection manager is parameterized, everything works. Even though the Conn Manger existed in the Conn Manger tab, the Conn Mgr is already listed in the Solution Explorer AND worked no problem 2 days prior.
Odd. Whatever. Microsoft being Microsoft. SQL Server being SQL Server. Choose your poison.

'It' requires a dll file called cvextern.dll . 'It' can be either your own cs file or some other third party dll which you are using in your project.
To call native dlls to your own cs file, copy the dll into your project's root\lib directory and add it as an existing item. (Add -Existing item) and use Dllimport with correct location.
For third party , copy the native library to the folder where the third party library resides and add it as an existing item.
After building make sure that the required dlls are appearing in Build folder. In some cases it may not appear or get replaced in Build folder. Delete the Build folder manually and build again.
1.Edit settings.gradle file, change rootProject.name
rootProject.name = "FirebaseDemo"
include ':app'
2.Go to the project file folder, rename the file folder
3.Delete .idea folder in your project and rebuild the project
you can easily access elements by index , by use System.Linq
Here is the sample
First add using in your class file
using System.Linq;
Then
yourDictionaryData.ElementAt(i).Key
yourDictionaryData.ElementAt(i).Value
Hope this helps.
If you are not using eclipse. Then you can change the ant java property directly on the file as mentioned here.

Take a look at this: Entity Framework don't create database
I would try giving the database a different name. Sometimes you can run into problems with SQL Express when trying to create a database with the same name a second time. There is a way to fix this using SQL Server Management Studio but it's generally easier to just use a different database name.
Edit This answer was accepted because it confirms the bug and the workaround used by OP (renaming database could help). I totally agree that renaming the database is not really an acceptable way, and does not totally solve the issue. Unfortunatly I didn't check the other ways to really solve it in SSMS.
You should not need to add this back in. This was removed purposefully. The documentation has changed somewhat and the CSS class that is necessary ("nav-stacked") is only mentioned under the pills component, but should work for tabs as well.
This tutorial shows how to use the Bootstrap 3 setup properly to do vertical tabs:
tutsme-webdesign.info/bootstrap-3-toggable-tabs-and-pills
if (combo1.SelectedIndex > -1)
{
// do something
}
if any item is selected selected index will be greater than -1
I've been bitten before by (someone else's) "clever" code that tries to modify a list while iterating over it. I resolved that I would never do it under any circumstance.
You can use the slice operator mylist[::3]
to skip across to every third item in your list.
mylist = [i for i in range(100)]
for i in mylist[::3]:
print(i)
Other points about my example relate to new syntax in python 3.0.
Python 3.0 range() now behaves like xrange() used to behave, except it works with values of arbitrary size. The latter no longer exists.
Assuming you are running on a *nix platform, use cron
and the php
executable.
EDIT:
There are quite a number of questions asking for "running php without cron" on SO already. Here's one:
Schedule scripts without using CRON
That said, the exec() answer above sounds very promising :)
To extend on the answer of weijia.wang:
extension Data {
func hexString() -> String {
let nsdataStr = NSData.init(data: self)
return nsdataStr.description.trimmingCharacters(in: CharacterSet(charactersIn: "<>")).replacingOccurrences(of: " ", with: "")
}
}
use it with deviceToken.hexString()
If you want to print the bytes as chars you can use the String constructor.
byte[] bytes = new byte[] { -1, -128, 1, 127 };
System.out.println(new String(bytes, 0));
You can use following:
angular.element(domElement).scope()
to get the current scope for the element
angular.element(domElement).injector()
to get the current app injector
angular.element(domElement).controller()
to get a hold of the ng-controller instance.
Hope that might help
You can use the following code for your requirement
map.forEach((k,v)->System.out.println("Item : " + k + " Count : " + v));
To replace all spaces
:
UPDATE `table` SET `col_name` = REPLACE(`col_name`, ' ', '')
To remove all tabs
characters :
UPDATE `table` SET `col_name` = REPLACE(`col_name`, '\t', '' )
To remove all new line
characters :
UPDATE `table` SET `col_name` = REPLACE(`col_name`, '\n', '')
http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_replace
To remove first and last space(s)
of column :
UPDATE `table` SET `col_name` = TRIM(`col_name`)
http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_trim
For Bootstrap 3 and 4 it's
.collapsing {
-webkit-transition: none;
transition: none;
display: none;
}
The default JavaScript "API" for setting a cookie is as easy as:
document.cookie = 'mycookie=valueOfCookie;expires=DateHere;path=/'
Use the jQuery cookie plugin like:
$.cookie('mycookie', 'valueOfCookie')

Why Access-Control-Allow-Headers
, Access-Control-Expose-Headers
, Access-Control-Allow-Methods
values are super long?
Those do not support the *
syntax, so I've collected the most common (and exotic) headers from around the web, in various formats #1 #2 #3 (and I will update the list from time to time)
Why do you use Header unset ______
syntax?
GoDaddy servers (which my website is hosted on..) have a weird bug where if the headers are already set, the previous value will join the existing one.. (instead of replacing it) this way I "pre-clean" existing values (really just a a quick && dirty solution)
Is it safe for me to use 'as-is'?
Well.. mostly the answer would be YES since the .htaccess
is limiting the headers to the scripts (PHP, HTML, ...) and resources (.JPG, .JS, .CSS) served from the following "folder"-location. You optionally might want to remove the Access-Control-Allow-Methods
lines. Also Connection
, Time-Zone
, Keep-Alive
and DNT
, Accept-Ranges
, Vary
, X-UA-Compatible
, X-Frame-Options
, X-Content-Type-Options
and X-Xss-Protection
are just a suggestion I'm using for my online-service.. feel free to remove those too...
taken from my comment above
1st method
MyTable.objects.filter(pk=some_value).update(field1='some value')
2nd Method
q = MyModel.objects.get(pk=some_value)
q.field1 = 'some value'
q.save()
3rd method
By using get_object_or_404
q = get_object_or_404(MyModel,pk=some_value)
q.field1 = 'some value'
q.save()
4th Method
if you required if pk=some_value
exist then update
it other wise create
new one by using update_or_create
.
MyModel.objects.update_or_create(pk=some_value,defaults={'field1':'some value'})
For users coming back to this post long after the initial answer was accepted, it may pay off to note that now you can use
data-fancybox-href="#"
on any element (since data is an HTML-5 accepted attribute) to have the fancybox work on say an input form if for some reason you can't use the options to initiate for some reason (like say you have multiple elements on the page that use fancybox and they all share a similar class you call fancybox on).
You can use ACE in order to do so:
#include "ace/SOCK_Connector.h"
int main(int argc, ACE_TCHAR* argv[])
{
//HTTP Request Header
char* szRequest = "GET /video/nice.mp4 HTTP/1.1\r\nHost: example.com\r\n\r\n";
int ilen = strlen(szRequest);
//our buffer
char output[16*1024];
ACE_INET_Addr server (80, "example.com");
ACE_SOCK_Stream peer;
ACE_SOCK_Connector connector;
int ires = connector.connect(peer, server);
int sum = 0;
peer.send(szRequest, ilen);
while (true)
{
ACE_Time_Value timeout = ACE_Time_Value(15);
int rc = peer.recv_n(output, 16*1024, &timeout);
if (rc == -1)
{
break;
}
sum += rc;
}
peer.close();
printf("Bytes transffered: %d",sum);
return 0;
}
Why and when you should mark the request
parameter as implicit
:
Some methods that you will make use of in the body of your action have an implicit parameter list like, for example, Form.scala defines a method:
def bindFromRequest()(implicit request: play.api.mvc.Request[_]): Form[T] = { ... }
You don't necessarily notice this as you would just call myForm.bindFromRequest()
You don't have to provide the implicit arguments explicitly. No, you leave the compiler to look for any valid candidate object to pass in every time it comes across a method call that requires an instance of the request. Since you do have a request available, all you need to do is to mark it as implicit
.
You explicitly mark it as available for implicit use.
You hint the compiler that it's "OK" to use the request object sent in by the Play framework (that we gave the name "request" but could have used just "r" or "req") wherever required, "on the sly".
myForm.bindFromRequest()
see it? it's not there, but it is there!
It just happens without your having to slot it in manually in every place it's needed (but you can pass it explicitly, if you so wish, no matter if it's marked implicit
or not):
myForm.bindFromRequest()(request)
Without marking it as implicit, you would have to do the above. Marking it as implicit you don't have to.
When should you mark the request as implicit
? You only really need to if you are making use of methods that declare an implicit parameter list expecting an instance of the Request. But to keep it simple, you could just get into the habit of marking the request implicit
always. That way you can just write beautiful terse code.
I think it will help you to understand the basic differences between Inline-Elements (e.g. span) and Block-Elements (e.g. div), in order to understand why "display: inline-block" is so useful.
Problem: inline elements (e.g. span, a, button, input etc.) take "margin" only horizontally (margin-left and margin-right) on, not vertically. Vertical spacing works only on block elements (or if "display:block" is set)
Solution: Only through "display: inline-block" will also take the vertical distance (top and bottom). Reason: Inline element Span, behaves now like a block element to the outside, but like an inline element inside
Here Code Examples:
/* Inlineelement */
div,
span {
margin: 30px;
}
span {
outline: firebrick dotted medium;
background-color: antiquewhite;

span.mitDisplayBlock {

}

}

<h1> The Box model - content, padding, border, margin</h1>
<h2> Inline element - span</h2>
<span>Info: A span element can not have height and width (not without "display: block"), which means it takes the fixed inline size </span>
<span class="beispielMargin">
<b>Problem:</b> inline elements (eg span, a, button, input etc.) take "margin" only vertically (margin-left and margin-right)
on, not horizontal. Vertical spacing works only on block elements (or if display: block is set) </span>
<span class="beispielMarginDisplayInlineBlock">
<b>Solution</b> Only through
<b> "display: inline-block" </ b> will also take the vertical distance (top and bottom). Reason: Inline element Span,
behaves now like a block element to the outside, but like an inline element inside</span>
<span class="beispielMarginDisplayInline">Example: here "display: inline". See the margin with Inspector!</span>
<span class="beispielMarginDisplayBlock">Example: here "display: block". See the margin with Inspector!</span>
<span class="beispielMarginDisplayInlineBlock">Example: here "display: inline-block". See the margin with Inspector! </span>
<span class="mitDisplayBlock">Only with the "Display" -property and "block" -Value in addition, a width and height can be assigned. "span" is then like
a "div" block element. </span>

You may want to have a look at the documentation too.
If you are using Jackson Serializer, here is a way to use the date modules:
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.datatype.jdk8.Jdk8Module;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import com.fasterxml.jackson.module.paramnames.ParameterNamesModule;
import org.apache.kafka.common.serialization.Serializer;
public class JacksonSerializer<T> implements Serializer<T> {
private final ObjectMapper mapper = new ObjectMapper()
.registerModule(new ParameterNamesModule())
.registerModule(new Jdk8Module())
.registerModule(new JavaTimeModule());
@Override
public byte[] serialize(String s, T object) {
try {
return mapper.writeValueAsBytes(object);
} catch (JsonProcessingException e) {
e.printStackTrace();
}
return null;
}
}
The recommended way to do this from the current v4 docs is:
$font-size-base: 0.8rem;
$line-height-base: 1;
Be sure to define the variables above the bootstrap css include and they will override the bootstrap.
No need for anything else and this is the cleanest way
It's described quite clearly in the docs https://getbootstrap.com/docs/4.1/content/typography/#global-settings
More about "load average" showing CPU load over 1 minute, 5 minutes and 15 minutes
Linux, Mac, and other Unix-like systems display “load average” numbers. These numbers tell you how busy your system’s CPU, disk, and other resources are. They’re not self-explanatory at first, but it’s easy to become familiar with them.
WIKI: example, one can interpret a load average of "1.73 0.60 7.98" on a single-CPU system as:
during the last minute, the system was overloaded by 73% on average (1.73 runnable processes, so that 0.73 processes had to wait for a turn for a single CPU system on average).
during the last 5 minutes, the CPU was idling 40% of the time on average.
during the last 15 minutes, the system was overloaded 698% on average (7.98 runnable processes, so that 6.98 processes had to wait for a turn for a single CPU system on average) if dual core mean: 798% - 200% = 598%.
You probably have a system with multiple CPUs or a multi-core CPU. The load average numbers work a bit differently on such a system. For example, if you have a load average of 2 on a single-CPU system, this means your system was overloaded by 100 percent — the entire period of time, one process was using the CPU while one other process was waiting. On a system with two CPUs, this would be complete usage — two different processes were using two different CPUs the entire time. On a system with four CPUs, this would be half usage — two processes were using two CPUs, while two CPUs were sitting idle.
To understand the load average number, you need to know how many CPUs your system has. A load average of 6.03 would indicate a system with a single CPU was massively overloaded, but it would be fine on a computer with 8 CPUs.

To account for leading and trailing whitespace, you probably want to use normalize-space()
//div[contains(@class, 'Caption') and normalize-space(.)='Model saved']
and
//div[@id='alertLabel' and normalize-space(.)='Save to server successful']
Note that //div[contains(@class, 'Caption') and normalize-space(.//text())='Model saved']
also works.

(EDITED to work with Android Studio 3.0 and Gradle 4)
I was looking for a more complex apk filename renaming option and I wrote this solution that renames the apk with the following data:
You would get an apk like this: myProject_dev_debug_1.3.6_131016_1047.apk.
You can find the whole answer here. Hope it helps!
In the build.gradle:
android {
...
buildTypes {
release {
minifyEnabled true
...
}
debug {
minifyEnabled false
}
}
productFlavors {
prod {
applicationId "com.feraguiba.myproject"
versionCode 3
versionName "1.2.0"
}
dev {
applicationId "com.feraguiba.myproject.dev"
versionCode 15
versionName "1.3.6"
}
}
applicationVariants.all { variant ->
variant.outputs.all { output ->
def project = "myProject"
def SEP = "_"
def flavor = variant.productFlavors[0].name
def buildType = variant.variantData.variantConfiguration.buildType.name
def version = variant.versionName
def date = new Date();
def formattedDate = date.format('ddMMyy_HHmm')
def newApkName = project + SEP + flavor + SEP + buildType + SEP + version + SEP + formattedDate + ".apk"
outputFileName = new File(newApkName)
}
}
}
I was facing the same error. The solution that worked for me is:
From the server end, while returning JSON response, change the content-type: text/html
Now the browsers (Chrome, Firefox and IE8) do not give an error.
Without setting the width
, it will get the maximum width it can get. So you cannot see that the div
has centered.
#container
{
width: 50%;
height: auto;
margin: auto;
padding: 10px;
position: relative;
background-color: black; /* Just to see the different */
}
What you could do is also to take the next token as a String, converts this string to a char array and test that each character in the array is a digit.
I think that's correct, if you don't want to deal with the exceptions.
The problem is that flex: 1
sets flex-basis: 0

Try specifying the engine='python'. It worked for me but I'm still trying to figure out why.
df = pd.read_csv(input_file_path,...engine='python')
If you got node __dirname not defined
with node --experimental-modules
, you can do :
const __dirname = path.dirname(import.meta.url)
.replace(/^file:\/\/\//, '') // can be usefull
Because othe example, work only with current/pwd directory not other directory.
for i=1,#target do
game.Players.target[i].Character:BreakJoints()
end
Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:
game.Players.target.1.Character:BreakJoints()
Which is completely incorrect.
c = game.Players:GetChildren()
Never use "Players:GetChildren()", it is not guaranteed to return only players.
Instead use:
c = Game.Players:GetPlayers()
if msg:lower()=="me" then
table.insert(people, source)
return people
Here you add the player's name in the list "people", where you in the other places adds the player object.
Fixed code:
local Admins = {"FakeNameHereSoNoStalkers"}
function Kill(Players)
for i,Player in ipairs(Players) do
if Player.Character then
Player.Character:BreakJoints()
end
end
end
function IsAdmin(Player)
for i,AdminName in ipairs(Admins) do
if Player.Name:lower() == AdminName:lower() then return true end
end
return false
end
function GetPlayers(Player,Msg)
local Targets = {}
local Players = Game.Players:GetPlayers()
if Msg:lower() == "me" then
Targets = { Player }
elseif Msg:lower() == "all" then
Targets = Players
elseif Msg:lower() == "others" then
for i,Plr in ipairs(Players) do
if Plr ~= Player then
table.insert(Targets,Plr)
end
end
else
for i,Plr in ipairs(Players) do
if Plr.Name:lower():sub(1,Msg:len()) == Msg then
table.insert(Targets,Plr)
end
end
end
return Targets
end
Game.Players.PlayerAdded:connect(function(Player)
if IsAdmin(Player) then
Player.Chatted:connect(function(Msg)
if Msg:lower():sub(1,6) == ":kill " then
Kill(GetPlayers(Player,Msg:sub(7)))
end
end)
end
end)
string s = "Hello Marco !";
s = s.Remove(s.length - 2, 2);
This for the Api you could use
const express = require('express');
const bodyParser = require('body-parser');
const app = express();
var multer = require('multer');
const port = 8000;
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.listen(port, ()=>{
console.log('We are live on' + port);
});
var upload = multer({dest:'./upload/'});
app.post('/post', upload.single('file'), function(req, res) {
console.log(req.file);
res.send("file saved on server");
});
This also works fine used on Postman but the file doesn't comes with .jpg extension any Advice? As commented below
This is the default feature of multer if uploads file with no extension, however, provides you the the file object, using which you can update the extension of the file.
var filename = req.file.filename;
var mimetype = req.file.mimetype;
mimetype = mimetype.split("/");
var filetype = mimetype[1];
var old_file = configUploading.settings.rootPathTmp+filename;
var new_file = configUploading.settings.rootPathTmp+filename+'.'+filetype;
rname(old_file,new_file);
I know it's an old question, but if someone is looking here again... see https://python-sounddevice.readthedocs.io/en/0.4.1/index.html .
It has a nice example "Input to Ouput Pass-Through" here https://python-sounddevice.readthedocs.io/en/0.4.1/examples.html#input-to-output-pass-through .
... and a lot of other examples as well ...
You can refresh using JavaScript. Rather than the complete page refresh, you can give the contents to be refreshed in a div. Then by using JavaScript you can refresh that particular div only, and it works faster than the complete page refresh.
Right. In most, if not all implementations of C, the array identifier can be implicitly casted to a pointer to the first element (i.e. the first element's address). What you're doing here is comparing those addresses, which is obviously wrong.
Instead, you need to iterate over both arrays, checking each element against each other. If you get to the end of both without a failure, they're equal.
one more variation - this looks for the program "cmd.exe" in the current path and reports the first match:
@echo off
setlocal
setlocal enableextensions
setlocal enabledelayedexpansion
set P=%PATH%
:pathloop
for /F "delims=; tokens=1*" %%f in ("!P!") do (
set F=%%f
if exist %%f\cmd.exe goto found
set P=%%g
)
if defined P goto pathloop
echo path of cmd.exe was not found!
goto end
:found
echo found cmd.exe at %F%
goto end
:end
Just ran into this problem myself. OSx Lion hides scrollbars while not in use to make it seem more "slick", but at the same time the issue you addressed comes up: people sometimes cannot see whether a div has a scroll feature or not.

border-radius: 4px;
background-color: rgba(0, 0, 0, .5);

in OpenCV 3.0 you can use it easily as follow:
#combine 2 images same as to concatenate images with two different sizes
h1, w1 = img1.shape[:2]
h2, w2 = img2.shape[:2]
#create empty martrix (Mat)
res = np.zeros(shape=(max(h1, h2), w1 + w2, 3), dtype=np.uint8)
# assign BGR values to concatenate images
for i in range(res.shape[2]):
# assign img1 colors
res[:h1, :w1, i] = np.ones([img1.shape[0], img1.shape[1]]) * img1[:, :, i]
# assign img2 colors
res[:h2, w1:w1 + w2, i] = np.ones([img2.shape[0], img2.shape[1]]) * img2[:, :, i]
output_img = res.astype('uint8')
I've seen this problem a few times (got it again right now on my home computer with Eclipse 4.2).
Forcing a resave (by changing the classpath e.g. by adding a library, save, change-back) works temporarily. But the problem comes back when Eclipse is restarted :(
Nuking the Eclipse workspace from orbit will permanently fix it (until next time). But there must be a better way!
Give the name to both of the buttons and Get the check the value from form.
<div>
<input name="submitButton" type="submit" value="Register" />
</div>
<div>
<input name="cancelButton" type="submit" value="Cancel" />
</div>
On controller side :
public ActionResult Save(FormCollection form)
{
if (this.httpContext.Request.Form["cancelButton"] !=null)
{
// return to the action;
}
else if(this.httpContext.Request.Form["submitButton"] !=null)
{
// save the oprtation and retrun to the action;
}
}
Instead of extrapolating off the ends, you could return the extents of the y_list
. Most of the time your application is well behaved, and the Interpolate[x]
will be in the x_list
. The (presumably) linear affects of extrapolating off the ends may mislead you to believe that your data is well behaved.
Returning a non-linear result (bounded by the contents of x_list
and y_list
) your program's behavior may alert you to an issue for values greatly outside x_list
. (Linear behavior goes bananas when given non-linear inputs!)
Returning the extents of the y_list
for Interpolate[x]
outside of x_list
also means you know the range of your output value. If you extrapolate based on x
much, much less than x_list[0]
or x
much, much greater than x_list[-1]
, your return result could be outside of the range of values you expected.
def __getitem__(self, x):
if x <= self.x_list[0]:
return self.y_list[0]
elif x >= self.x_list[-1]:
return self.y_list[-1]
else:
i = bisect_left(self.x_list, x) - 1
return self.y_list[i] + self.slopes[i] * (x - self.x_list[i])
Since you are conditionally indexing df$est
, you also need to conditionally index the replacement vector df$a
:
index <- df$b == 0
df$est[index] <- (df$a[index] - 5)/2.533
Of course, the variable index
is just temporary, and I use it to make the code a bit more readible. You can write it in one step:
df$est[df$b == 0] <- (df$a[df$b == 0] - 5)/2.533
For even better readibility, you can use within
:
df <- within(df, est[b==0] <- (a[b==0]-5)/2.533)
The results, regardless of which method you choose:
df
a b est
1 11.77000 2 0.000000
2 10.90000 3 0.000000

As others have pointed out, an alternative solution in your example is to use ifelse
.
Be careful using the answer provide by @DevNG. Arrays.asList() returns internal implementation of ArrayList that doesn't implement some useful methods like add(), delete(), etc. If you call them an UnsupportedOperationException will be thrown. In order to get real ArrayList instance you need to write something like this:
List<Video> = new ArrayList<>(Arrays.asList(videoArray));
The on-heap store refers to objects that will be present in the Java heap (and also subject to GC). On the other hand, the off-heap store refers to (serialized) objects that are managed by EHCache, but stored outside the heap (and also not subject to GC). As the off-heap store continues to be managed in memory, it is slightly slower than the on-heap store, but still faster than the disk store.
The internal details involved in management and usage of the off-heap store aren't very evident in the link posted in the question, so it would be wise to check out the details of Terracotta BigMemory, which is used to manage the off-disk store. BigMemory (the off-heap store) is to be used to avoid the overhead of GC on a heap that is several Megabytes or Gigabytes large. BigMemory uses the memory address space of the JVM process, via direct ByteBuffers that are not subject to GC unlike other native Java objects.
The most elegant solution to this problem is here.
Original answer remains, but this is a messy solution:
If you want to change the PYTHONPATH
used in a virtualenv, you can add the following line to your virtualenv's bin/activate
file:
export PYTHONPATH="/the/path/you/want"
This way, the new PYTHONPATH
will be set each time you use this virtualenv.
EDIT: (to answer @RamRachum's comment)
To have it restored to its original value on deactivate
, you could add
export OLD_PYTHONPATH="$PYTHONPATH"
before the previously mentioned line, and add the following line to your bin/postdeactivate
script.
export PYTHONPATH="$OLD_PYTHONPATH"
SELECT CONVERT(nvarchar(6), GETDATE(), 112)
By default, MomentJS parses in local time. If only a date string (with no time) is provided, the time defaults to midnight.
In your code, you create a local date and then convert it to the UTC timezone (in fact, it makes the moment instance switch to UTC mode), so when it is formatted, it is shifted (depending on your local time) forward or backwards.
If the local timezone is UTC+N (N being a positive number), and you parse a date-only string, you will get the previous date.
Here are some examples to illustrate it (my local time offset is UTC+3 during DST):
>>> moment('07-18-2013', 'MM-DD-YYYY').utc().format("YYYY-MM-DD HH:mm")
"2013-07-17 21:00"
>>> moment('07-18-2013 12:00', 'MM-DD-YYYY HH:mm').utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 09:00"
>>> Date()
"Thu Jul 25 2013 14:28:45 GMT+0300 (Jerusalem Daylight Time)"
If you want the date-time string interpreted as UTC, you should be explicit about it:
>>> moment(new Date('07-18-2013 UTC')).utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"
or, as Matt Johnson mentions in his answer, you can (and probably should) parse it as a UTC date in the first place using moment.utc()
and include the format string as a second argument to prevent ambiguity.
>>> moment.utc('07-18-2013', 'MM-DD-YYYY').format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"
To go the other way around and convert a UTC date to a local date, you can use the local()
method, as follows:
>>> moment.utc('07-18-2013', 'MM-DD-YYYY').local().format("YYYY-MM-DD HH:mm")
"2013-07-18 03:00"
Use Shift+Del.
More info: Shift+Del combination key set a field to null when you filled a field by a value and you changed your decision and you want to make it null. It is useful and I amazed from the other answers that give strange solutions.
This error message is often misleading.
You may have forgotten to import the BrowserAnimationsModule
. But that was not my problem. I was importing BrowserAnimationsModule
in the root AppModule
, as everyone should do.
The problem was something completely unrelated to the module. I was animating an*ngIf
in the component template but I had forgotten to mention it in the @Component.animations
for the component class.
@Component({
selector: '...',
templateUrl: './...',
animations: [myNgIfAnimation] // <-- Don't forget!
})
If you use an animation in a template, you also must list that animation in the component's animations
metadata ... every time.

instinctively went with this...
int address = (int)&var;

unsigned long address = reinterpret_cast(&var);
comment told me this is correct...

You have a stale version of the package with commands that no longer accept zookeeper but rather bootstrap-server as the connection. Confluent will then connect with Zookeeper internally.

Your question is: "How can I see exactly what happened in the someFunction() that caused the exception to happen?"
It seems to me that you are not asking about how to handle unforeseen exceptions in production code (as many answers assumed), but how to find out what is causing a particular exception during development.
The easiest way is to use a debugger that can stop where the uncaught exception occurs, preferably not exiting, so that you can inspect the variables. For example, PyDev in the Eclipse open source IDE can do that. To enable that in Eclipse, open the Debug perspective, select Manage Python Exception Breakpoints
in the Run
menu, and check Suspend on uncaught exceptions
.
do not forget add "use Illuminate\Http\Request;" on your controller

I don't think min/max validations attribute exist. I would use something like
[Range(1, Int32.MaxValue)]
for minimum value 1 and
[Range(Int32.MinValue, 10)]
for maximum value 10
The classical solution is:
expr 5 \* 5
expr
will only work with integer operands. Another nice option is:
echo 5 5\*p | dc
dc
can be made to work with non-integer operands.
SQL Server Express doesn't include SQL Server Agent, so it's not possible to just create SQL Agent jobs.
What you can do is:
You can create jobs "manually" by creating batch files and SQL script files, and running them via Windows Task Scheduler.
For example, you can backup your database with two files like this:
backup.bat:
sqlcmd -i backup.sql
backup.sql:
backup database TeamCity to disk = 'c:\backups\MyBackup.bak'
Just put both files into the same folder and exeute the batch file via Windows Task Scheduler.
The first file is just a Windows batch file which calls the sqlcmd utility and passes a SQL script file.
The SQL script file contains T-SQL. In my example, it's just one line to backup a database, but you can put any T-SQL inside. For example, you could do some UPDATE
queries instead.
If the jobs you want to create are for backups, index maintenance or integrity checks, you could also use the excellent Maintenance Solution by Ola Hallengren.
It consists of a bunch of stored procedures (and SQL Agent jobs for non-Express editions of SQL Server), and in the FAQ there’s a section about how to run the jobs on SQL Server Express:
How do I get started with the SQL Server Maintenance Solution on SQL Server Express?
SQL Server Express has no SQL Server Agent. Therefore, the execution of the stored procedures must be scheduled by using cmd files and Windows Scheduled Tasks. Follow these steps.
SQL Server Express has no SQL Server Agent. Therefore, the execution of the stored procedures must be scheduled by using cmd files and Windows Scheduled Tasks. Follow these steps.
Download MaintenanceSolution.sql.
Execute MaintenanceSolution.sql. This script creates the stored procedures that you need.
Create cmd files to execute the stored procedures; for example:
sqlcmd -E -S .\SQLEXPRESS -d master -Q "EXECUTE dbo.DatabaseBackup @Databases = 'USER_DATABASES', @Directory = N'C:\Backup', @BackupType = 'FULL'" -b -o C:\Log\DatabaseBackup.txtIn Windows Scheduled Tasks, create tasks to call the cmd files.
Schedule the tasks.
Start the tasks and verify that they are completing successfully.
For me, it worked:
button.setCompoundDrawablesWithIntrinsicBounds(com.example.project1.R.drawable.ic_launcher, 0, 0, 0);

You cannot append to an existing xlsx file with xlsxwriter
.
There is a module called openpyxl which allows you to read and write to preexisting excel file, but I am sure that the method to do so involves reading from the excel file, storing all the information somehow (database or arrays), and then rewriting when you call workbook.close()
which will then write all of the information to your xlsx file.
Similarly, you can use a method of your own to "append" to xlsx documents. I recently had to append to a xlsx file because I had a lot of different tests in which I had GPS data coming in to a main worksheet, and then I had to append a new sheet each time a test started as well. The only way I could get around this without openpyxl was to read the excel file with xlrd and then run through the rows and columns...
i.e.
cells = []
for row in range(sheet.nrows):
cells.append([])
for col in range(sheet.ncols):
cells[row].append(workbook.cell(row, col).value)
You don't need arrays, though. For example, this works perfectly fine:
import xlrd
import xlsxwriter
from os.path import expanduser
home = expanduser("~")
# this writes test data to an excel file
wb = xlsxwriter.Workbook("{}/Desktop/test.xlsx".format(home))
sheet1 = wb.add_worksheet()
for row in range(10):
for col in range(20):
sheet1.write(row, col, "test ({}, {})".format(row, col))
wb.close()
# open the file for reading
wbRD = xlrd.open_workbook("{}/Desktop/test.xlsx".format(home))
sheets = wbRD.sheets()
# open the same file for writing (just don't write yet)
wb = xlsxwriter.Workbook("{}/Desktop/test.xlsx".format(home))
# run through the sheets and store sheets in workbook
# this still doesn't write to the file yet
for sheet in sheets: # write data from old file
newSheet = wb.add_worksheet(sheet.name)
for row in range(sheet.nrows):
for col in range(sheet.ncols):
newSheet.write(row, col, sheet.cell(row, col).value)
for row in range(10, 20): # write NEW data
for col in range(20):
newSheet.write(row, col, "test ({}, {})".format(row, col))
wb.close() # THIS writes
However, I found that it was easier to read the data and store into a 2-dimensional array because I was manipulating the data and was receiving input over and over again and did not want to write to the excel file until it the test was over (which you could just as easily do with xlsxwriter since that is probably what they do anyway until you call .close()
).
$(function () {
$('#datetimepicker9').datetimepicker({
viewMode: 'years',
format: 'DD/MM/YYYY' /*Add this line to remove time format*/
});
});
Invoke-Expression
, also aliased as iex
. The following will work on your examples #2 and #3:
iex $command
Some strings won't run as-is, such as your example #1 because the exe is in quotes. This will work as-is, because the contents of the string are exactly how you would run it straight from a Powershell command prompt:
$command = 'C:\somepath\someexe.exe somearg'
iex $command
However, if the exe is in quotes, you need the help of &
to get it running, as in this example, as run from the commandline:
>> &"C:\Program Files\Some Product\SomeExe.exe" "C:\some other path\file.ext"
And then in the script:
$command = '"C:\Program Files\Some Product\SomeExe.exe" "C:\some other path\file.ext"'
iex "& $command"
Likely, you could handle nearly all cases by detecting if the first character of the command string is "
, like in this naive implementation:
function myeval($command) {
if ($command[0] -eq '"') { iex "& $command" }
else { iex $command }
}
But you may find some other cases that have to be invoked in a different way. In that case, you will need to either use try{}catch{}
, perhaps for specific exception types/messages, or examine the command string.
If you always receive absolute paths instead of relative paths, you shouldn't have many special cases, if any, outside of the 2 above.
A great Spring MVC quickstart archetype is available on GitHub, courtesy of kolorobot. Good instructions are provided on how to install it to your local Maven repo and use it to create a new Spring MVC project. He’s even helpfully included the Tomcat 7 Maven plugin in the archetypical project so that the newly created Spring MVC can be run from the command line without having to manually deploy it to an application server.
Kolorobot’s example application includes the following:
You can simply use this:
'07311954' in df.date.values
which returns True
or False
Here is the further explanation:
In pandas, using in
check directly with DataFrame and Series (e.g. val in df
or val in series
) will check whether the val
is contained in the Index.
BUT you can still use in
check for their values too (instead of Index)! Just using val in df.col_name.values
or val in series.values
. In this way, you are actually checking the val
with a Numpy array.
And .isin(vals)
is the other way around, it checks whether the DataFrame/Series values are in the vals
. Here vals
must be set or list-like. So this is not the natural way to go for the question.
Look at ?par
for the various graphics parameters.
In general cex
controls size, col
controls colour. If you want to control the colour of a label, the par
is col.lab
, the colour of the axis annotations col.axis
, the colour of the main
text, col.main
etc. The names are quite intuitive, once you know where to begin.
For example
x <- 1:10
y <- 1:10
plot(x , y,xlab="x axis", ylab="y axis", pch=19, col.axis = 'blue', col.lab = 'red', cex.axis = 1.5, cex.lab = 2)
If you need to change the colour / style of the surrounding box and axis lines, then look at ?axis
or ?box
, and you will find that you will be using the same parameter names within calls to box
and axis.
You have a lot of control to make things however you wish.
eg
plot(x , y,xlab="x axis", ylab="y axis", pch=19, cex.lab = 2, axes = F,col.lab = 'red')
box(col = 'lightblue')
axis(1, col = 'blue', col.axis = 'purple', col.ticks = 'darkred', cex.axis = 1.5, font = 2, family = 'serif')
axis(2, col = 'maroon', col.axis = 'pink', col.ticks = 'limegreen', cex.axis = 0.9, font =3, family = 'mono')
Which is seriously ugly, but shows part of what you can control
I made the mistake of opening a BufferedReader like:
File f = new File("somefile.txt");
BufferedReader br = new BufferedReader(new FileReader(f));
...and of course I could not execute the f.delete()
because I wrapped the
FileReader instead of instantiating its own variable where I could explicitly close it. Duh...
Once I coded:
File f = new File("somefile.txt");
FileReader fread = new FileReader(f);
BufferedReader br = new BufferedReader(fread);
I could issue a br.close(); br=null; fread.close(); fread=null;
and the f.delete()
worked fine.
This was always the question I had when I was working on one of my application which created massive number of threads per request.
So this is a really good question and there are two aspects of this:
1. Whether my Xms and Xmx value should be same
- Most websites and even oracle docs suggest it to be the same. However, I suggest to have some 10-20% of buffer between those values to give heap resizing an option to your application in case sudden high traffic spikes OR a incidental memory leak.
2. Whether I should start my Application with lower heap size
- So here's the thing - no matter what GC Algo you use (even G1), large heap always has some trade off. The goal is to identify the behavior of your application to what heap size you can allow your GC pauses in terms of latency and throughput.
- For example, if your application has lot of threads (each thread has 1 MB stack in native memory and not in heap) but does not occupy heavy object space, then I suggest have a lower value of Xms.
- If your application creates lot of objects with increasing number of threads, then identify to what value of Xms you can set to tolerate those STW pauses. This means identify the max response time of your incoming requests you can tolerate and according tune the minimum heap size.
const http = require('http');
const url = require('url');
http.createServer((req,res)=>{
const parseObj = url.parse(req.url,true);
const users = [{id:1,name:'soura'},{id:2,name:'soumya'}]
if(parseObj.pathname == '/user-details' && req.method == "GET") {
let Id = parseObj.query.id;
let user_details = {};
users.forEach((data,index)=>{
if(data.id == Id){
user_details = data;
}
})
res.writeHead(200,{'x-auth-token':'Auth Token'})
res.write(JSON.stringify(user_details)) // Json to String Convert
res.end();
}
}).listen(8000);
I have used the above code in my existing project.
Inspired by Jon Skeet, I have extended his solution with the following:
Extension Method:
public static void Execute<TSource, TKey>(this IEnumerable<TSource> source, Action<TKey> applyBehavior, Func<TSource, TKey> keySelector)
{
foreach (var item in source)
{
var target = keySelector(item);
applyBehavior(target);
}
}
Client:
var jobs = new List<Job>()
{
new Job { Id = "XAML Developer" },
new Job { Id = "Assassin" },
new Job { Id = "Narco Trafficker" }
};
jobs.Execute(ApplyFilter, j => j.Id);
. . .
public void ApplyFilter(string filterId)
{
Debug.WriteLine(filterId);
}
I think you should go with request parameters but only as long as there isn't an appropriate HTTP header to accomplish what you want to do. The HTTP specification does not explicitly say, that GET can not have a body. However this paper states:
By convention, when GET method is used, all information required to identify the resource is encoded in the URI. There is no convention in HTTP/1.1 for a safe interaction (e.g., retrieval) where the client supplies data to the server in an HTTP entity body rather than in the query part of a URI. This means that for safe operations, URIs may be long.
If you give each one a name, the clicked one will be sent through as any other input.

You need to increase the watches limit to fix the recompile issue on save, Open terminal and enter these two commands:
sudo sysctl fs.inotify.max_user_watches=524288
sudo sysctl -p --system
To make the changes persistent even after restart, run this command also:
echo fs.inotify.max_user_watches=524288 | sudo tee /etc/sysctl.d/40-max-user-watches.conf && sudo sysctl --system

Set yourlabel's leading and trailing constraint = 0 (using Autolayout)
You can add as many headers as you like by calling addHeaderView() multiple times. You have to do it before setting the adapter to the list view.
And yes you can add header something like this way:
LayoutInflater inflater = getLayoutInflater();
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.header, myListView, false);
myListView.addHeaderView(header, null, false);

In the your first journey in spring boot project I recommend you to start with Spring Starter Try this link here.
It will auto generate the project structure for you like this.application.perperties it will be under /resources.
application.properties important change,
server.port = Your PORT(XXXX) by default=8080
server.servlet.context-path=/api (SpringBoot version 2.x.)
server.contextPath-path=/api (SpringBoot version < 2.x.)
Any way you can use application.yml in case you don't want to make redundancy properties setting.
Example
application.yml
server:
port: 8080
contextPath: /api
application.properties
server.port = 8080
server.contextPath = /api

This enables you to do it within one command line without having to echo a text file. This answer builds on top of @mti2935's answer. So credit goes there.

Sample code :
$headers = "From: [email protected]\r\n";
$headers .= "Reply-To: [email protected]\r\n";
$headers .= "Return-Path: [email protected]\r\n";
$headers .= "CC: [email protected]\r\n";
$headers .= "BCC: [email protected]\r\n";
if ( mail($to,$subject,$message,$headers) ) {
echo "The email has been sent!";
} else {
echo "The email has failed!";

Eloquent has a method for that (Laravel 4.*/5.*);
Model::whereNotNull('sent_at')
Laravel 3:

When using tfoot, the footer on the last page does not stay nicely on the bottom. This is because table footers are meant for tables, not physical pages.

describe
may give you everything you want otherwise you can perform aggregations using groupby and pass a list of agg functions: http://pandas.pydata.org/pandas-docs/stable/groupby.html#applying-multiple-functions-at-once

Note that some columns cannot be summarised as there is no logical way to summarise them, for instance columns containing string data
As you prefer you can transpose the result if you prefer:
In [47]:
df.describe().transpose()
Out[47]:
count mean std min 25% 50% 75% max
shopper_num 14 7.5 4.1833 1 4.25 7.5 10.75 14
is_martian 14 0 0 False 0 0 0 False
number_of_items 14 3.357143 6.452276 0 0 0 3.5 22
count_pineapples 14 0 0 0 0 0 0 0
[4 rows x 8 columns]
Try
var ts = TimeSpan.Parse(stringTime);
With a newer .NET you also have
TimeSpan ts;
if(!TimeSpan.TryParse(stringTime, out ts)){
// throw exception or whatnot
}
// ts now has a valid format
This is the general idiom for parsing strings in .NET with the first version handling erroneous string by throwing FormatException and the latter letting the Boolean TryParse give you the information directly.
If we want to add numbers of an Array and find the average of them follow this easy way! .....
public class Array {
public static void main(String[] args) {
int[]array = {1,3,5,7,9,6,3};
int i=0;
int sum=0;
double average=0;
for( i=0;i<array.length;i++){
System.out.println(array[i]);
sum=sum+array[i];
}
System.out.println("sum is:"+sum);
System.out.println("average is: "+(double)sum/vargu.length);
}
}
>>> value=42
>>> print "Value is %s"%('"'+str(value)+'"')
Value is "42"
