Assuming that your original dataset is similar to the one you created (i.e. with NA
as character
. You could specify na.strings
while reading the data using read.table
. But, I guess NAs would be detected automatically.
The price
column is factor
which needs to be converted to numeric
class. When you use as.numeric
, all the non-numeric elements (i.e. "NA"
, FALSE) gets coerced to NA
) with a warning.
library(dplyr)
df %>%
mutate(price=as.numeric(as.character(price))) %>%
group_by(company, year, product) %>%
summarise(total.count=n(),
count=sum(is.na(price)),
avg.price=mean(price,na.rm=TRUE),
max.price=max(price, na.rm=TRUE))
I am using the same dataset
(except the ...
row) that was showed.
df = tbl_df(data.frame(company=c("Acme", "Meca", "Emca", "Acme", "Meca","Emca"),
year=c("2011", "2010", "2009", "2011", "2010", "2013"), product=c("Wrench", "Hammer",
"Sonic Screwdriver", "Fairy Dust", "Kindness", "Helping Hand"), price=c("5.67",
"7.12", "12.99", "10.99", "NA",FALSE)))
I've used killableprocess successfully on Windows, Linux and Mac. If you are using Cygwin Python, you'll need OSAF's version of killableprocess because otherwise native Windows processes won't get killed.
I got around it by wrapping the supplied runnable submitted to the executor.
CompletableFuture.runAsync(() -> {
try {
runnable.run();
} catch (Throwable e) {
Log.info(Concurrency.class, "runAsync", e);
}
}, executorService);
I use:
function isString(s) {
return typeof(s) === 'string' || s instanceof String;
}
Because in JavaScript strings can be literals or objects.
The Content-Security-Policy
meta-tag allows you to reduce the risk of XSS attacks by allowing you to define where resources can be loaded from, preventing browsers from loading data from any other locations. This makes it harder for an attacker to inject malicious code into your site.
I banged my head against a brick wall trying to figure out why I was getting CSP errors one after another, and there didn't seem to be any concise, clear instructions on just how does it work. So here's my attempt at explaining some points of CSP briefly, mostly concentrating on the things I found hard to solve.
For brevity I won’t write the full tag in each sample. Instead I'll only show the content
property, so a sample that says content="default-src 'self'"
means this:
<meta http-equiv="Content-Security-Policy" content="default-src 'self'">
1. How can I allow multiple sources?
You can simply list your sources after a directive as a space-separated list:
content="default-src 'self' https://example.com/js/"
Note that there are no quotes around parameters other than the special ones, like 'self'
. Also, there's no colon (:
) after the directive. Just the directive, then a space-separated list of parameters.
Everything below the specified parameters is implicitly allowed. That means that in the example above these would be valid sources:
https://example.com/js/file.js
https://example.com/js/subdir/anotherfile.js
These, however, would not be valid:
http://example.com/js/file.js
^^^^ wrong protocol
https://example.com/file.js
^^ above the specified path
2. How can I use different directives? What do they each do?
The most common directives are:
default-src
the default policy for loading javascript, images, CSS, fonts, AJAX requests, etcscript-src
defines valid sources for javascript filesstyle-src
defines valid sources for css filesimg-src
defines valid sources for imagesconnect-src
defines valid targets for to XMLHttpRequest (AJAX), WebSockets or EventSource. If a connection attempt is made to a host that's not allowed here, the browser will emulate a 400
errorThere are others, but these are the ones you're most likely to need.
3. How can I use multiple directives?
You define all your directives inside one meta-tag by terminating them with a semicolon (;
):
content="default-src 'self' https://example.com/js/; style-src 'self'"
4. How can I handle ports?
Everything but the default ports needs to be allowed explicitly by adding the port number or an asterisk after the allowed domain:
content="default-src 'self' https://ajax.googleapis.com http://example.com:123/free/stuff/"
The above would result in:
https://ajax.googleapis.com:123
^^^^ Not ok, wrong port
https://ajax.googleapis.com - OK
http://example.com/free/stuff/file.js
^^ Not ok, only the port 123 is allowed
http://example.com:123/free/stuff/file.js - OK
As I mentioned, you can also use an asterisk to explicitly allow all ports:
content="default-src example.com:*"
5. How can I handle different protocols?
By default, only standard protocols are allowed. For example to allow WebSockets ws://
you will have to allow it explicitly:
content="default-src 'self'; connect-src ws:; style-src 'self'"
^^^ web Sockets are now allowed on all domains and ports.
6. How can I allow the file protocol file://
?
If you'll try to define it as such it won’t work. Instead, you'll allow it with the filesystem
parameter:
content="default-src filesystem"
7. How can I use inline scripts and style definitions?
Unless explicitly allowed, you can't use inline style definitions, code inside <script>
tags or in tag properties like onclick
. You allow them like so:
content="script-src 'unsafe-inline'; style-src 'unsafe-inline'"
You'll also have to explicitly allow inline, base64 encoded images:
content="img-src data:"
8. How can I allow eval()
?
I'm sure many people would say that you don't, since 'eval is evil' and the most likely cause for the impending end of the world. Those people would be wrong. Sure, you can definitely punch major holes into your site's security with eval, but it has perfectly valid use cases. You just have to be smart about using it. You allow it like so:
content="script-src 'unsafe-eval'"
9. What exactly does 'self'
mean?
You might take 'self'
to mean localhost, local filesystem, or anything on the same host. It doesn't mean any of those. It means sources that have the same scheme (protocol), same host, and same port as the file the content policy is defined in. Serving your site over HTTP? No https for you then, unless you define it explicitly.
I've used 'self'
in most examples as it usually makes sense to include it, but it's by no means mandatory. Leave it out if you don't need it.
But hang on a minute! Can't I just use content="default-src *"
and be done with it?
No. In addition to the obvious security vulnerabilities, this also won’t work as you'd expect. Even though some docs claim it allows anything, that's not true. It doesn't allow inlining or evals, so to really, really make your site extra vulnerable, you would use this:
content="default-src * 'unsafe-inline' 'unsafe-eval'"
... but I trust you won’t.

In some cases, Jason's answer is overkill. And $('.ui-widget-overlay').click(function(){ $("#dialog").dialog("close"); });
doesn't always work with dynamic content.
The solution that I find works in all cases is:
$('body').on('click','.ui-widget-overlay',function(){ $('#dialog').dialog('close'); });
Use jQuery. You need to capture the click
event and then go on to the website.
$("#myHref").on('click', function() {_x000D_
alert("inside onclick");_x000D_
window.location = "http://www.google.com";_x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<a href="#" id="myHref">Click me</a>
_x000D_
To solve the problem of:
E: Unable to locate package python-pip
you should do this. This works with the python2.7 and you not going to get disappointed by it.
follow the steps that are mention below.
go to get-pip.py and copy all the code from it.
open the terminal using CTRL + ALT +T
vi get-pip.py
paste the copied code here and then exit from the vi editor by pressing
ESC then :wq => press Enter
lastly, now run the code and see the magic
sudo python get-pip.py
It automatically adds the pip command in your Linux.

I think that you could use a POST or PATCH method to handle this since they typically design for this.
Using a POST
method is typically used to add an element when used on list resource but you can also support several actions for this method. See this answer: How to Update a REST Resource Collection. You can also support different representation formats for the input (if they correspond to an array or a single elements).
In the case, it's not necessary to define your format to describe the update.
Using a PATCH
method is also suitable since corresponding requests correspond to a partial update. According to RFC5789 (http://tools.ietf.org/html/rfc5789):
Several applications extending the Hypertext Transfer Protocol (HTTP) require a feature to do partial resource modification. The existing HTTP PUT method only allows a complete replacement of a document. This proposal adds a new HTTP method, PATCH, to modify an existing HTTP resource.
In the case, you have to define your format to describe the partial update.
I think that in this case, POST
and PATCH
are quite similar since you don't really need to describe the operation to do for each element. I would say that it depends on the format of the representation to send.
The case of PUT
is a bit less clear. In fact, when using a method PUT
, you should provide the whole list. As a matter of fact, the provided representation in the request will be in replacement of the list resource one.
You can have two options regarding the resource paths.
In this case, you need to explicitely provide the link of docs with a binder in the representation you provide in the request.
Here is a sample route for this /docs
.
The content of such approach could be for method POST
:
[
{ "doc_number": 1, "binder": 4, (other fields in the case of creation) },
{ "doc_number": 2, "binder": 4, (other fields in the case of creation) },
{ "doc_number": 3, "binder": 5, (other fields in the case of creation) },
(...)
]
In addition you could also consider to leverage sub routes to describe the link between docs and binders. The hints regarding the association between a doc and a binder doesn't have now to be specified within the request content.
Here is a sample route for this /binder/{binderId}/docs
. In this case, sending a list of docs with a method POST
or PATCH
will attach docs to the binder with identifier binderId
after having created the doc if it doesn't exist.
The content of such approach could be for method POST
:
[
{ "doc_number": 1, (other fields in the case of creation) },
{ "doc_number": 2, (other fields in the case of creation) },
{ "doc_number": 3, (other fields in the case of creation) },
(...)
]
Regarding the response, it's up to you to define the level of response and the errors to return. I see two levels: the status level (global level) and the payload level (thinner level). It's also up to you to define if all the inserts / updates corresponding to your request must be atomic or not.
In this case, you can leverage the HTTP status. If everything goes well, you get a status 200
. If not, another status like 400
if the provided data aren't correct (for example binder id not valid) or something else.
In this case, a status 200
will be returned and it's up to the response representation to describe what was done and where errors eventually occur. ElasticSearch has an endpoint in its REST API for bulk update. This could give you some ideas at this level: http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/bulk.html.
You can also implement an asynchronous processing to handle the provided data. In this case, the HTTP status returns will be 202
. The client needs to pull an additional resource to see what happens.
Before finishing, I also would want to notice that the OData specification addresses the issue regarding relations between entities with the feature named navigation links. Perhaps could you have a look at this ;-)

The best way is to create special source folder named resources
and use it for all resource including log4j.properties. So, just put it there.
On the Java Resources folder that was automatically created by the Dynamic Web Project, right click and add a new Source Folder and name it 'resources'. Files here will then be exported to the war file to the classes directory
Float#round can take a parameter in Ruby 1.9, not in Ruby 1.8. JRuby defaults to 1.8, but it is capable of running in 1.9 mode.
5.0//2
results in 2.0
, and not 2
because the return type of the return value from //
operator follows python coercion (type casting) rules.
Python promotes conversion of lower datatype (integer) to higher data type (float) to avoid data loss.

If you declare a variable in a function static, its value will not be stored on the function call stack and will still be available when you call the function again.
If you declare a global variable static, its scope will be restricted to within the file in which you declared it. This is slightly safer than a regular global which can be read and modified throughout your entire program.

This utilizes the COM interface and automatically indicates that admin privileges are needed with the familiar dialog prompt that you would see if you were copying into a directory where admin privileges are required and also provides the typical file progress dialog during the copy operation.
As a couple of answers have pointed out, I believe there is some some misunderstanding of multi tier vs MVC architecture.
Multi tier architecture involves breaking your application into tiers/layers (e.g. presentation, business logic, data access)
MVC is an architectural style for the presentation layer of an application. For non trivial applications, business logic/business rules/data access should not be placed directly into Models, Views, or Controllers. To do so would be placing business logic in your presentation layer and thus reducing reuse and maintainability of your code.
The model is a very reasonable choice choice to place business logic, but a better/more maintainable approach is to separate your presentation layer from your business logic layer and create a business logic layer and simply call the business logic layer from your models when needed. The business logic layer will in turn call into the data access layer.
I would like to point out that it is not uncommon to find code that mixes business logic and data access in one of the MVC components, especially if the application was not architected using multiple tiers. However, in most enterprise applications, you will commonly find multi tier architectures with an MVC architecture in place within the presentation layer.
In windows server 2012, even after installing asp.net you might run into this issue.
Check for "Http activation" feature. This feature is present under Web services as well.

My Source: http://htmlhelp.com/tools/validator/problems.html#amp
Another common error occurs when including a URL which contains an ampersand ("&"):
This is invalid:
a href="foo.cgi?chapter=1§ion=2©=3&lang=en"
Explanation:
This example generates an error for "unknown entity section" because the
"&"
is assumed to begin an entity reference. Browsers often recover safely from this kind of error, but real problems do occur in some cases. In this example, many browsers correctly convert ©=3 to ©=3, which may cause the link to fail. Since 〈 is the HTML entity for the left-pointing angle bracket, some browsers also convert &lang=en to <=en. And one old browser even finds the entity §, converting §ion=2 to §ion=2.
So the goal here is to avoid problems when you are trying to validate your website. So you should be replacing your ampersands with &
when writing a URL in your markup.
Note that replacing
&
with&
; is only done when writing the URL in HTML, where"&"
is a special character (along with "<" and ">"). When writing the same URL in a plain text email message or in the location bar of your browser, you would use"&"
and not"&"
. With HTML, the browser translates"&"
to"&"
so the Web server would only see"&"
and not"&"
in the query string of the request.
Hope this helps : )
The default sqlite library that comes with iOS is not compiled using the SQLITE_THREADSAFE macro on. This could be a reason why your code crashes.
You can do the following. Add your ggplot code after the first line of code and end with dev.off()
.
tiff("test.tiff", units="in", width=5, height=5, res=300)
# insert ggplot code
dev.off()
res=300
specifies that you need a figure with a resolution of 300 dpi. The figure file named 'test.tiff' is saved in your working directory.
Change width
and height
in the code above depending on the desired output.
Note that this also works for other R
plots including plot
, image
, and pheatmap
.
Other file formats
In addition to TIFF, you can easily use other image file formats including JPEG, BMP, and PNG. Some of these formats require less memory for saving.

As @KyssTao has been saying, help(dates.num2date)
says that the x
has to be a float giving the number of days since 0001-01-01 plus one. Hence, 19910102
is not 2/Jan/1991, because if you counted 19910101 days from 0001-01-01 you'd get something in the year 54513 or similar (divide by 365.25, number of days in a year).
Use datestr2num
instead (see help(dates.datestr2num)
):
new_x = dates.datestr2num(date) # where date is '01/02/1991'
Try to do <a href="#" class="arrow">
instead. (Note the sharp #
character).
The real reason because set
does not work is the fact, that it uses the hash function to distinguish different values. This means that sets only allows hashable objects. Why a list is not hashable is already pointed out.
Turns out that Entity Framework will assume that any class that inherits from a POCO class that is mapped to a table on the database requires a Discriminator column, even if the derived class will not be saved to the DB.
The solution is quite simple and you just need to add [NotMapped]
as an attribute of the derived class.
Example:
class Person
{
public string Name { get; set; }
}
[NotMapped]
class PersonViewModel : Person
{
public bool UpdateProfile { get; set; }
}
Now, even if you map the Person class to the Person table on the database, a "Discriminator" column will not be created because the derived class has [NotMapped]
.
As an additional tip, you can use [NotMapped]
to properties you don't want to map to a field on the DB.
A simple, although awk-less solution in bash:
while IFS=, read -r a a a b; do echo "$a"; done <inputfile
It works faster for small files (<100 lines) then awk as it uses less resources (avoids calling the expensive fork
and execve
system calls).
EDIT from Ed Morton (sorry for hi-jacking the answer, I don't know if there's a better way to address this):
To put to rest the myth that shell will run faster than awk for small files:
$ wc -l file
99 file
$ time while IFS=, read -r a a a b; do echo "$a"; done <file >/dev/null
real 0m0.016s
user 0m0.000s
sys 0m0.015s
$ time awk -F, '{print $3}' file >/dev/null
real 0m0.016s
user 0m0.000s
sys 0m0.015s
I expect if you get a REALY small enough file then you will see the shell script run in a fraction of a blink of an eye faster than the awk script but who cares?
And if you don't believe that it's harder to write robust shell scripts than awk scripts, look at this bug in the shell script you posted:
$ cat file
a,b,-e,d
$ cut -d, -f3 file
-e
$ awk -F, '{print $3}' file
-e
$ while IFS=, read -r a a a b; do echo "$a"; done <file

I was searching for a fix on this and the folder i was ADD or COPY'ing was not in the build folder, multiple directories above or referenced from /
Moving the folder from outside the build folder into the build folder fixed my issue.

Finally I found a decission - reinstalling of rvm helped me. Probably it can save time somebody else.

From https://en.wikipedia.org/wiki/Web_server
A web server is a computer system that processes requests via HTTP, the basic network protocol used to distribute information on the World Wide Web. The term can refer to the entire system, or specifically to the software that accepts and supervises the HTTP requests.
From https://en.wikipedia.org/wiki/Application_server#Application_Server_definition
An application server runs behind a web Server (e.g. Apache or Microsoft Internet Information Services (IIS)) and (almost always) in front of an SQL database (e.g. PostgreSQL, MySQL, or Oracle).
Web applications are computer code which run atop application servers and are written in the language(s) the application server supports and call the runtime libraries and components the application server offers.
You'll want to use .indexOf()
and .splice()
. Something like:
tag_story.splice(tag_story.indexOf(90),1);
As for the workaround (without using non-portable -P
), you can temporary replace a new-line character with the different one and change it back, e.g.:
grep -o "_foo_" <(paste -sd_ file) | tr -d '_'
Basically it's looking for exact match _foo_
where _
means \n
(so __
= \n\n
). You don't have to translate it back by tr '_' '\n'
, as each pattern would be printed in the new line anyway, so removing _
is enough.
Github documentation contains a script that replaces the committer info for all commits in a branch.
Run the following script from terminal after changing the variable values

if [ "$GIT_AUTHOR_EMAIL" = "$OLD_EMAIL" ]
then
export GIT_AUTHOR_NAME="$CORRECT_NAME"
export GIT_AUTHOR_EMAIL="$CORRECT_EMAIL"
fi
' --tag-name-filter cat -- --branches --tags
Push the corrected history to GitHub:
git push --force --tags origin 'refs/heads/*'
OR if you like to push selected references of the branches then use
git push --force --tags origin 'refs/heads/develop'
Here is the way you can do with Javascript Promise.
const getBase64 = (file) => new Promise(function (resolve, reject) {
let reader = new FileReader();
reader.readAsDataURL(file);
reader.onload = () => resolve(reader.result)
reader.onerror = (error) => reject('Error: ', error);
})
Now, use it in event handler.
const _changeImg = (e) => {
const file = e.target.files[0];
let encoded;
getBase64(file)
.then((result) => {
encoded = result;
})
.catch(e => console.log(e))

I know this is not the OP's problem, but I ran into the same error with an entirely different basis, so I just wanted to drop it here in case anyone else has the same. This is Windows-specific, and I assume does not affect Linux users.
I had a LibreOffice doc file, call it final report.odt
. I later changed its case to Final Report.odt
. In Windows, this doesn't even count as a rename. final report.odt
, Final Report.odt
, FiNaL RePoRt.oDt
are all the same. In Linux, these are all distinct.
When I eventually went to git rm "Final Report.odt"
and got the "pathspec did not match any files" error. Only when I use the original casing at the time the file was added -- git rm "final report.odt"
-- did it work.
Lesson learned: to change the case I should have instead done:
git mv "final report.odt" temp.odt
git mv temp.odt "Final Report.odt"
Again, that wasn't the problem for the OP here; and wouldn't affect a Linux user, as his posts shows he clearly is. I'm just including it for others who may have this problem in Windows git and stumble onto this question.

Then links should point to this modal via data-target
attribute:
<a href="#myModal" data-toggle="modal" id="1" data-target="#edit-modal">Edit 1</a>
Finally Js part becomes very simple:
$('#edit-modal').on('show.bs.modal', function(e) {
var $modal = $(this),
esseyId = e.relatedTarget.id;
$.ajax({
cache: false,
type: 'POST',
url: 'backend.php',
data: 'EID=' + essayId,
success: function(data) {
$modal.find('.edit-content').html(data);
}
});
})

Get Drawable from vector resource irrespective of, whether its vector or not:
AppCompatResources.getDrawable(context, R.drawable.icon);
Note:
ContextCompat.getDrawable(context, R.drawable.icon);
will produce android.content.res.Resources$NotFoundException
for vector resource.
combining 3 answers together: (because a select statement does not execute the DDL)
set pagesize 0
alter session set skip_unusable_indexes = true;
spool c:\temp\disable_indexes.sql
select 'alter index ' || u.index_name || ' unusable;' from user_indexes u;
spool off
@c:\temp\disable_indexes.sql
Do import...
select 'alter index ' || u.index_name ||
' rebuild online;' from user_indexes u;
Note this assumes that the import is going to happen in the same (sqlplus) session.
If you are calling "imp" it will run in a separate session so you would need to use "ALTER SYSTEM" instead of "ALTER SESSION" (and remember to put the parameter back the way you found it.
The answer above (by Janusz) is quite correct, but I personnally don't feel 100% confortable with RelativeLayouts, so I prefer to introduce a 'filler', empty TextView, like this:
<!-- filler -->
<TextView android:layout_height="0dip"
android:layout_width="fill_parent"
android:layout_weight="1" />
before the element that should be at the bottom of the screen.
Hash results varies between 32bit and 64bit platforms
If a calculated hash shall be the same on both platforms consider using

For Swift 4
I used @Passkit's logic but i had to update as per Swift 4
Step.1 Created extension for String Class
import UIKit
extension String
{
var parseJSONString: AnyObject?
{
let data = self.data(using: String.Encoding.utf8, allowLossyConversion: false)
if let jsonData = data
{
// Will return an object or nil if JSON decoding fails
do
{
let message = try JSONSerialization.jsonObject(with: jsonData, options:.mutableContainers)
if let jsonResult = message as? NSMutableArray
{
print(jsonResult)
return jsonResult //Will return the json array output
}
else
{
return nil
}
}
catch let error as NSError
{
print("An error occurred: \(error)")
return nil
}
}
else
{
// Lossless conversion of the string was not possible
return nil
}
}
}
Step.2 This is how I used in my view controller
var jsonString = "[\n" +
"{\n" +
"\"id\":72,\n" +
"\"name\":\"Batata Cremosa\",\n" +
"},\n" +
"{\n" +
"\"id\":183,\n" +
"\"name\":\"Caldeirada de Peixes\",\n" +
"},\n" +
"{\n" +
"\"id\":76,\n" +
"\"name\":\"Batata com Cebola e Ervas\",\n" +
"},\n" +
"{\n" +
"\"id\":56,\n" +
"\"name\":\"Arroz de forma\",\n" +
"}]"
//Convert jsonString to jsonArray
let json: AnyObject? = jsonString.parseJSONString
print("Parsed JSON: \(json!)")
print("json[2]: \(json![2])")
All credit goes to original user, I just updated for latest swift version
I had this error aswell.
I am working in mysql workbench. When giving the values they have to be inside "". That solved it for me.
None of the existing answers involve using a comparator, and therefore cannot be used in binary trees or for sorting. So I'm just gonna leave this here:
public static int compareIntArrays(int[] a, int[] b) {
if (a == null) {
return b == null ? 0 : -1;
}
if (b == null) {
return 1;
}
int cmp = a.length - b.length;
if (cmp != 0) {
return cmp;
}
for (int i = 0; i < a.length; i++) {
cmp = Integer.compare(a[i], b[i]);
if (cmp != 0) {
return cmp;
}
}
return 0;
}
I think this is the right way to make a shape like you want. By using the SVG possibilities, and an container to keep the shape responsive.
svg {_x000D_

top: 0;_x000D_
left: 0;_x000D_
}_x000D_
.container {_x000D_
display: inline-block;_x000D_
position: relative;_x000D_
width: 100%;_x000D_
padding-bottom: 100%;_x000D_
vertical-align: middle;_x000D_

}

My server is CentOS 7, and I install tomcat by:
sudo yum install tomcat
sudo yum install tomcat-webapps tomcat-admin-webapps
I found my webapps folders in:
/usr/share/tomcat/
and
/var/lib/tomcat/
df=pd.read_csv("filename.csv" , parse_dates=["<column name>"])
type(df.<column name>)
example: if you want to convert day which is initially a string to a Timestamp in Pandas
df=pd.read_csv("weather_data2.csv" , parse_dates=["day"])
type(df.day)
The output will be pandas.tslib.Timestamp
First if the object you're dealing with is a string then you need to parse it then figure out the length of the keys :
obj = JSON.parse(jsonString);
shareInfoLen = Object.keys(obj.shareInfo[0]).length;
The 4K limit you read about is for the entire cookie, including name, value, expiry date etc. If you want to support most browsers, I suggest keeping the name under 4000 bytes, and the overall cookie size under 4093 bytes.
One thing to be careful of: if the name is too big you cannot delete the cookie (at least in JavaScript). A cookie is deleted by updating it and setting it to expire. If the name is too big, say 4090 bytes, I found that I could not set an expiry date. I only looked into this out of interest, not that I plan to have a name that big.
To read more about it, here are the "Browser Cookie Limits" for common browsers.
While on the subject, if you want to support most browsers, then do not exceed 50 cookies per domain, and 4093 bytes per domain. That is, the size of all cookies should not exceed 4093 bytes.
This means you can have 1 cookie of 4093 bytes, or 2 cookies of 2045 bytes, etc.
I used to say 4095 bytes due to IE7, however now Mobile Safari comes in with 4096 bytes with a 3 byte overhead per cookie, so 4093 bytes max.
You can use map
to return just the name, and then use this forEach
trick to check if it exists at least twice:
var areAnyDuplicates = false;
values.map(function(obj) {
return obj.name;
}).forEach(function (element, index, arr) {
if (arr.indexOf(element) !== index) {
areAnyDuplicates = true;
}
});
Arrays are pretty flexible in JS, you can do:
var myArray = new Array();
myArray.push("string 1");
myArray.push("string 2");
If you wish to create a pdf from php, pdflib will help you (as some others suggested).
Else, if you want to convert an HTML page to PDF via PHP, you'll find a little trouble outta here.. For 3 years I've been trying to do it as best as I can.
So, the options I know are:
DOMPDF : php class that wraps the html and builds the pdf. Works good, customizable (if you know php), based on pdflib, if I remember right it takes even some CSS. Bad news: slow when the html is big or complex.
HTML2PS: same as DOMPDF, but this one converts first to a .ps (ghostscript) file, then, to whatever format you need (pdf, jpg, png). For me is little better than dompdf, but has the same speed problem.. but, better compatibility with CSS.
Those two are php classes, but if you can install some software on the server, and access it throught passthru() or system(), give a look to these too:
wkhtmltopdf: based on webkit (safari's wrapper), is really fast and powerful.. seems like this is the best one (atm) for converting html pages to pdf on the fly; taking only 2 seconds for a 3 page xHTML document with CSS2. It is a recent project, anyway, the google.code page is often updated.
htmldoc : This one is a tank, it never really stops/crashes.. the project looks dead since 2007, but anyway if you don't need CSS compatibility this can be nice for you.
You can use BrowserMob proxy to capture the requests and responses with a HttpRequestInterceptor
. Here is an example in Java:
// Start the BrowserMob proxy
ProxyServer server = new ProxyServer(9978);
server.start();
server.addResponseInterceptor(new HttpResponseInterceptor()
{
@Override
public void process(HttpResponse response, HttpContext context)
throws HttpException, IOException
{
System.out.println(response.getStatusLine());
}
});
// Get selenium proxy
Proxy proxy = server.seleniumProxy();
// Configure desired capability for using proxy server with WebDriver
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.PROXY, proxy);
// Set up driver
WebDriver driver = new FirefoxDriver(capabilities);
driver.get("http://stackoverflow.com/questions/6509628/webdriver-get-http-response-code");
// Close the browser
driver.quit();
You could also do the following:
if (element.innerHTML.trim() !== '') {
// It has at least one
}
This uses the trim() method to treat empty elements which have only whitespaces (in which case hasChildNodes
returns true) as being empty.
NB: The above method doesn't filter out comments. (so a comment would classify a a child)
To filter out comments as well, we could make use of the read-only Node.nodeType property where Node.COMMENT_NODE
(A Comment node, such as <!-- … -->
) has the constant value - 8
if (element.firstChild?.nodeType !== 8 && element.innerHTML.trim() !== '' {
// It has at least one
}
let divs = document.querySelectorAll('div');
for(element of divs) {
if (element.firstChild?.nodeType !== 8 && element.innerHTML.trim() !== '') {
console.log('has children')
} else { console.log('no children') }
}
_x000D_
<div><span>An element</span>
<div>some text</div>
<div> </div> <!-- whitespace -->
<div><!-- A comment --></div>
<div></div>

There is indeed a big difference, which you should keep in mind. setScale really set the scale of your number whereas round does round your number to the specified digits BUT it "starts from the leftmost digit of exact result" as mentioned within the jdk. So regarding your sample the results are the same, but try 0.0034 instead. Here's my note about that on my blog:
http://araklefeistel.blogspot.com/2011/06/javamathbigdecimal-difference-between.html
Just make a new Date
object with the stamp's getTime()
value as a parameter.
Here's an example (I use an example timestamp of the current time):
Timestamp stamp = new Timestamp(System.currentTimeMillis());
Date date = new Date(stamp.getTime());
System.out.println(date);

Check that your remote host (i.e. the web hosting server you're trying to connect FROM) allows OUTGOING traffic on port 3306.
I saw the (100) error in this situation. I could connect from my PC/Mac, but not from my website. The MySQL instance was accessible via the internet, but my hosting company wasn't allowing my website to connect to the database on port 3306.
Once I asked my hosting company to open my web hosting account up to outgoing traffic on port 3306, my website could connect to my remote database.

It may be safer but took 4 hours to demuddle the philosophy...
Module
s are VB counterparts to C# static
classes. When your class is designed solely for helper functions and extension methods and you don't want to allow inheritance and instantiation, you use a Module
.
By the way, using Module
is not really subjective and it's not deprecated. Indeed you must use a Module
when it's appropriate. .NET Framework itself does it many times (System.Linq.Enumerable
, for instance). To declare an extension method, it's required to use Module
s.
Could anyone help explain why
In Python 2 a python "int" was equivalent to a C long. In Python 3 an "int" is an arbitrary precision type but numpy still uses "int" it to represent the C type "long" when creating arrays.
The size of a C long is platform dependent. On windows it is always 32-bit. On unix-like systems it is normally 32 bit on 32 bit systems and 64 bit on 64 bit systems.
or give a solution for the code on windows? Thanks so much!
Choose a data type whose size is not platform dependent. You can find the list at https://docs.scipy.org/doc/numpy/reference/arrays.scalars.html#arrays-scalars-built-in the most sensible choice would probably be np.int64
A lot of these answers are simplistic, and if someone is beginning WPF, they may not know all of the "ins-and-outs", as it is more complicated than just telling someone "Use .ShowDialog()
!". But that is the method (not .Show()
) that you want to use in order to block use of the underlying window and to keep the code from continuing until the modal window is closed.
First, you need 2 WPF windows. (One will be calling the other.)
From the first window, let's say that was called MainWindow.xaml, in its code-behind will be:
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
}
Then add your button to your XAML:
<Button Name="btnOpenModal" Click="btnOpenModal_Click" Content="Open Modal" />
And right-click the Click
routine, select "Go to definition". It will create it for you in MainWindow.xaml.cs:
private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
}
Within that function, you have to specify the other page using its page class. Say you named that other page "ModalWindow", so that becomes its page class and is how you would instantiate (call) it:
private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
ModalWindow modalWindow = new ModalWindow();
modalWindow.ShowDialog();
}
Say you have a value you need set on your modal dialog. Create a textbox and a button in the ModalWindow
XAML:
<StackPanel Orientation="Horizontal">
<TextBox Name="txtSomeBox" />
<Button Name="btnSaveData" Click="btnSaveData_Click" Content="Save" />
</StackPanel>
Then create an event handler (another Click
event) again and use it to save the textbox value to a public static variable on ModalWindow
and call this.Close()
.
public partial class ModalWindow : Window
{
public static string myValue = String.Empty;
public ModalWindow()
{
InitializeComponent();
}
private void btnSaveData_Click(object sender, RoutedEventArgs e)
{
myValue = txtSomeBox.Text;
this.Close();
}
}
Then, after your .ShowDialog()
statement, you can grab that value and use it:
private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
ModalWindow modalWindow = new ModalWindow();
modalWindow.ShowDialog();
string valueFromModalTextBox = ModalWindow.myValue;
}
static
A member declared with the keyword 'static'.
factory methods
Methods that create and return new objects.
in Java
The programming language is relevant to the meaning of 'static' but not to the definition of 'factory'.
PSH> $cred = Get-Credential
PSH> $cred | Export-CliXml c:\temp\cred.clixml
PSH> $cred2 = Import-CliXml c:\temp\cred.clixml
That hashes it against your SID and the machine's SID, so the file is useless on any other machine, or in anyone else's hands.
For PowerShell versions less than 3.0:
The FileInfo
object returned by Get-ChildItem
has a "base" property, PSIsContainer
. You want to select only those items.
Get-ChildItem -Recurse | ?{ $_.PSIsContainer }
If you want the raw string names of the directories, you can do
Get-ChildItem -Recurse | ?{ $_.PSIsContainer } | Select-Object FullName
For PowerShell 3.0 and greater:
Get-ChildItem -Directory
You can also use the aliases dir
, ls
, and gci
As above the question was originally about MySQL
Use REGEXP
, not LIKE
:
SELECT * FROM `table` WHERE ([url] NOT REGEXP '^[-A-Za-z0-9/.]+$')
You ca also use Response.Write("alert('Error')");
AndroidManifest.xml
Include launchMode="singleTop"
<activity android:name=".MessagesDetailsActivity"
android:launchMode="singleTop"
android:excludeFromRecents="true"
/>
SMSReceiver.java
Set the flags for the Intent and PendingIntent
Intent intent = new Intent(context, MessagesDetailsActivity.class);
intent.putExtra("smsMsg", smsObject.getMsg());
intent.putExtra("smsAddress", smsObject.getAddress());
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(context, notification_id, intent, PendingIntent.FLAG_UPDATE_CURRENT);
MessageDetailsActivity.java
onResume() - gets called everytime, load the extras.
Intent intent = getIntent();
String extraAddress = intent.getStringExtra("smsAddress");
String extraBody = intent.getStringExtra("smsMsg");
Hope it helps, it was based on other answers here on stackoverflow, but this is the most updated that worked for me.
Breaking news: I've added another answer that uses an Observable rather than an EventEmitter. I recommend that answer over this one. And actually, using an EventEmitter in a service is bad practice.
Original answer: (don't do this)
Put the EventEmitter into a service, which allows the ObservingComponent to directly subscribe (and unsubscribe) to the event:
import {EventEmitter} from 'angular2/core';
export class NavService {
navchange: EventEmitter<number> = new EventEmitter();
constructor() {}
emit(number) {
this.navchange.emit(number);
}
subscribe(component, callback) {
// set 'this' to component when callback is called
return this.navchange.subscribe(data => call.callback(component, data));
}
}
@Component({
selector: 'obs-comp',
template: 'obs component, index: {{index}}'
})
export class ObservingComponent {
item: number;
subscription: any;
constructor(private navService:NavService) {
this.subscription = this.navService.subscribe(this, this.selectedNavItem);
}
selectedNavItem(item: number) {
console.log('item index changed!', item);
this.item = item;
}
ngOnDestroy() {
this.subscription.unsubscribe();
}
}
@Component({
selector: 'my-nav',
template:`
<div class="nav-item" (click)="selectedNavItem(1)">item 1 (click me)</div>
`,
})
export class Navigation {
constructor(private navService:NavService) {}
selectedNavItem(item: number) {
console.log('selected nav item ' + item);
this.navService.emit(item);
}
}
If you try the Plunker, there are a few things I don't like about this approach:
subscribe()
so that the proper this
is set when the callback is calledUpdate: An alternative that solves the 2nd bullet is to have the ObservingComponent directly subscribe to the navchange
EventEmitter property:
constructor(private navService:NavService) {
this.subscription = this.navService.navchange.subscribe(data =>
this.selectedNavItem(data));
}
If we subscribe directly, then we wouldn't need the subscribe()
method on the NavService.
To make the NavService slightly more encapsulated, you could add a getNavChangeEmitter()
method and use that:
getNavChangeEmitter() { return this.navchange; } // in NavService
constructor(private navService:NavService) { // in ObservingComponent
this.subscription = this.navService.getNavChangeEmitter().subscribe(data =>
this.selectedNavItem(data));
}
You should always avoid using system()
because
You should use CreateProcess().
You can use Createprocess() to just start up an .exe and creating a new process for it. The application will run independent from the calling application.
Here's an example I used in one of my projects:
#include <windows.h>
VOID startup(LPCTSTR lpApplicationName)
{
// additional information
STARTUPINFO si;
PROCESS_INFORMATION pi;
// set the size of the structures
ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );
// start the program up
CreateProcess( lpApplicationName, // the path
argv[1], // Command line
NULL, // Process handle not inheritable
NULL, // Thread handle not inheritable
FALSE, // Set handle inheritance to FALSE
0, // No creation flags
NULL, // Use parent's environment block
NULL, // Use parent's starting directory
&si, // Pointer to STARTUPINFO structure
&pi // Pointer to PROCESS_INFORMATION structure (removed extra parentheses)
);
// Close process and thread handles.
CloseHandle( pi.hProcess );
CloseHandle( pi.hThread );
}
EDIT: The error you are getting is because you need to specify the path of the .exe file not just the name. Openfile.exe probably doesn't exist.
My solution will work if you apply the ActionFilter to the Subcategory action method, as long as you always want to redirect the user to the same bookmark:
http://spikehd.blogspot.com/2012/01/mvc3-redirect-action-to-html-bookmark.html
It modifies the HTML buffer and outputs a small piece of javascript to instruct the browser to append the bookmark.
You could modify the javascript to manually scroll, instead of using a bookmark in the URL, of course!
Hope it helps :)
You'll first require to close the file using fclose($handle);
it's not deleting because the file is in use. So first close the file and then try.
You just have override the getView
method of ArrayAdapter
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(),
android.R.layout.simple_list_item_1, mStringList) {
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
TextView text = (TextView) view.findViewById(android.R.id.text1);
text.setTextColor(Color.BLACK);
return view;
}
};
This is really more of a serverfault-type question, but you can use netstat.
something like:
# netstat -lpnt | grep 6000 | grep ssh
This will tell you if there's an ssh process listening on the specified port. it will also tell you the PID of the process.
If you really want to double-check that the ssh process was started with the right options, you can then look up the process by PID in something like
# ps aux | grep PID
On top of @unutbu answer, you could coerce pandas numpy object array to native (float64) type, something along the line
import pandas as pd
pd.to_numeric(df['tester'], errors='coerce')
Specify errors='coerce' to force strings that can't be parsed to a numeric value to become NaN. Column type would be dtype: float64
, and then isnan
check should work
You may be looking for the Git feature called submodules. This feature helps you manage dependent repositories that are nested inside your main repository.
You can use this format as of 4/6/2017.
https://docs.google.com/viewerng/viewer?url=http://yourfile.pdf
Just replace http://yourfile.pdf with the link you use.
Maybe not safe and pretty but if you must:
class string
{
private $Text;
public function __construct($value)
{
$this->Text = $value;
}
public function __toString()
{
return $this->Text;
}
}
function Test123(string $s)
{
echo $s;
}
Test123(new string("Testing"));

It is easier to remove the "Default Web Site" and create a new one if you do not have any limitations.
I did it and my problem solved.
Values known at compile time can (and in my opinion should) be marked as constant.
Naming conventions should follow Java ones and should be properly visible when used from Java code (it's somehow hard to achieve with companion objects, but anyway).
The proper constant declarations are:
const val MY_CONST = "something"
const val MY_INT = 1
Just use the system("pause");
command.
All the other answers over complicate the issue.

What is DATA ACCESS OBJECT (DAO) -
It is a object/interface, which is used to access data from database of data storage.
WHY WE USE DAO:
it abstracts the retrieval of data from a data resource such as a database. The concept is to "separate a data resource's client interface from its data access mechanism."
The problem with accessing data directly is that the source of the data can change. Consider, for example, that your application is deployed in an environment that accesses an Oracle database. Then it is subsequently deployed to an environment that uses Microsoft SQL Server. If your application uses stored procedures and database-specific code (such as generating a number sequence), how do you handle that in your application? You have two options:
Its in all referred as DAO Pattern, It consist of following:
Please check this example, This will clear things more clearly.
Example
I assume this things must have cleared your understanding of DAO up to certain extend.
Use following interface to communicate between activity and fragment
public interface BundleListener {
void update(Bundle bundle);
Bundle getBundle();
}
Or use following this generic listener for two way communication using interface
/**
* Created by Qamar4P on 10/11/2017.
*/
public interface GenericConnector<T,E> {
T getData();
void updateData(E data);
void connect(GenericConnector<T,E> connector);
}
fragment show method
public static void show(AppCompatActivity activity) {
CustomValueDialogFragment dialog = new CustomValueDialogFragment();
dialog.connector = (GenericConnector) activity;
dialog.show(activity.getSupportFragmentManager(),"CustomValueDialogFragment");
}
you can cast your context to GenericConnector
in onAttach(Context)
too
in your activity
CustomValueDialogFragment.show(this);
in your fragment
...
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
connector.connect(new GenericConnector() {
@Override
public Object getData() {
return null;
}
@Override
public void updateData(Object data) {
}
@Override
public void connect(GenericConnector connector) {
}
});
}
...
public static void show(AppCompatActivity activity, GenericConnector connector) {
CustomValueDialogFragment dialog = new CustomValueDialogFragment();
dialog.connector = connector;
dialog.show(activity.getSupportFragmentManager(),"CustomValueDialogFragment");
}
Note: Never use it like "".toString().toString().toString();

Angular convention : write business logic in controller and DOM manipulation in link.
Apart from this you can call one controller function from link function of another directive.For example you have 3 custom directives
<animal>
<panther>
<leopard></leopard>
</panther>
</animal>
and you want to access animal from inside of "leopard" directive.
http://egghead.io/lessons/angularjs-directive-communication will be helpful to know about inter-directive communication
Just to give an alternative solution, because it isn't mentioned.
It's perfectly fine to use the HTML attribute defer
here. So when loading the DOM, a regular <script>
will load when the DOM hits the script. But if we use defer
, then the DOM and the script will load in parallel. The cool thing is the script gets evaluated in the end - when the DOM has loaded (source).
<script src="{% static "build/react.js" %}" defer></script>
This is what events are for.
HTMLInputElementObject.addEventListener('input', function (evt) {
something(this.value);
});
In case it helps someone, I had a similar issue and the error was because of two reasons:
Not using the app's namespace before the url name
{% url 'app_name:url_name' %}
Missing single quotes around the url name (as pointed out here by Charlie)
It's really simple to fix the issue, however keep in mind that you should fork and commit your changes for each library you are using in their repositories to help others as well.
Let's say you have something like this in your code:
$str = "test";
echo($str{0});
since PHP 7.4 curly braces method to get individual characters inside a string has been deprecated, so change the above syntax into this:
$str = "test";
echo($str[0]);
Fixing the code in the question will look something like this:
public function getRecordID(string $zoneID, string $type = '', string $name = ''): string
{
$records = $this->listRecords($zoneID, $type, $name);
if (isset($records->result[0]->id)) {
return $records->result[0]->id;
}
return false;
}
Yes: logrotate --force $CONFIG_FILE
sorted()
returns a new sorted list, leaving the original list unaffected. list.sort()
sorts the list in-place, mutating the list indices, and returns None
(like all in-place operations).
sorted()
works on any iterable, not just lists. Strings, tuples, dictionaries (you'll get the keys), generators, etc., returning a list containing all elements, sorted.
Use list.sort()
when you want to mutate the list, sorted()
when you want a new sorted object back. Use sorted()
when you want to sort something that is an iterable, not a list yet.
For lists, list.sort()
is faster than sorted()
because it doesn't have to create a copy. For any other iterable, you have no choice.
No, you cannot retrieve the original positions. Once you called list.sort()
the original order is gone.
There are several ways to achieve this.
Use a media query, but it requires font sizes for several breakpoints:
body
{
font-size: 22px;
}
h1
{
font-size: 44px;
}
@media (min-width: 768)
{
body
{
font-size: 17px;
}
h1
{
font-size: 24px;
}
}
Use dimensions in % or em. Just change the base font size, and everything will change. Unlike the previous one, you could just change the body font and not h1 every time or let the base font size be the default of the device and the rest all in em
:
CSS 3 supports new dimensions that are relative to the view port. But this doesn't work on Android:
3.2vmax = Bigger of 3.2vw or 3.2vh
body
{
font-size: 3.2vw;
}
See CSS-Tricks ... and also look at Can I Use...
This is years later, working on a legacy site... For the life of me I couldn't get the ->andWhere()
or ->expr()->in()
solutions working.
Finally looked in the Doctrine mongodb-odb repo and found some very revealing tests:
public function testQueryWhereIn()
{
$qb = $this->dm->createQueryBuilder('Documents\User');
$choices = array('a', 'b');
$qb->field('username')->in($choices);
$expected = [
'username' => ['$in' => $choices],
];
$this->assertSame($expected, $qb->getQueryArray());
}
It worked for me!
You can find the tests on github here. Useful for clarifying all sorts of nonsense.
Note: My setup is using Doctrine MongoDb ODM v1.0.dev as far as i can make out.
Another way to do this is to add the new characters to the string as follows:
Dim str As String
str = ""
To append text to your string this way:
str = str & "and this is more text"
This can be done entirely with bash string manipulation:
first="I love Suzy and Mary"
second="Sara"
first=${first/Suzy/$second}
That will replace only the first occurrence; to replace them all, double the first slash:
first="Suzy, Suzy, Suzy"
second="Sara"
first=${first//Suzy/$second}
# first is now "Sara, Sara, Sara"
Try this
var div = document.getElementById("test");
var spans = div.getElementsByTagName("span");
for(i=0;i<spans.length;i++)
{
alert(spans[i].innerHTML);
}
First you need to use this command
npm config set registry https://registry.your-registry.npme.io/
This we are doing to set our companies Enterprise registry as our default registry.
You can try other given solutions also.
You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-tree
option for single commands, or the GIT_WORK_TREE
environment variable. There is also the core.worktree
configuration option but it will not work in a bare repository (check the man page for what it does).
# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status
For global use, you may use:
$val = $_REQUEST['subject'];
and to add yo your session, simply
session_start();
$_SESSION['subject'] = $val;
And you dont need jQuery in this case.
For those of you that care about order (i.e. want your memcmp
to return an int
like it should instead of nothing), .NET Core 3.0 (and presumably .NET Standard 2.1 aka .NET 5.0) will include a Span.SequenceCompareTo(...)
extension method (plus a Span.SequenceEqualTo
) that can be used to compare two ReadOnlySpan<T>
instances (where T: IComparable<T>
).
In the original GitHub proposal, the discussion included approach comparisons with jump table calculations, reading a byte[]
as long[]
, SIMD usage, and p/invoke to the CLR implementation's memcmp
.
Going forward, this should be your go-to method for comparing byte arrays or byte ranges (as should using Span<byte>
instead of byte[]
for your .NET Standard 2.1 APIs), and it is sufficiently fast enough that you should no longer care about optimizing it (and no, despite the similarities in name it does not perform as abysmally as the horrid Enumerable.SequenceEqual
).
#if NETCOREAPP3_0
// Using the platform-native Span<T>.SequenceEqual<T>(..)
public static int Compare(byte[] range1, int offset1, byte[] range2, int offset2, int count)
{
var span1 = range1.AsSpan(offset1, count);
var span2 = range2.AsSpan(offset2, count);
return span1.SequenceCompareTo(span2);
// or, if you don't care about ordering
// return span1.SequenceEqual(span2);
}
#else
// The most basic implementation, in platform-agnostic, safe C#
public static bool Compare(byte[] range1, int offset1, byte[] range2, int offset2, int count)
{
// Working backwards lets the compiler optimize away bound checking after the first loop
for (int i = count - 1; i >= 0; --i)
{
if (range1[offset1 + i] != range2[offset2 + i])
{
return false;
}
}
return true;
}
#endif
FSO.js wraps the new HTML5 FileSystem API that's being standardized by the W3C and provides an extremely easy way to read from, write to, or traverse a local sandboxed file system. It's asynchronous, so file I/O will not interfere with user experience. :)
in case you have a variable :
$your_var = 'declare your var';
echo 'i want to show my var here'.$your_var.'<br>';

For information this comes under Item 48 - Avoid float and double when exact values are required, of Effective Java 2nd edition by Joshua Bloch. This book is jam packed with good stuff and definitely worth a look.
Ross has the right idea for POSTing the usual parameter/value format to a url.
I recently ran into a situation where I needed to POST some XML as Content-Type "text/xml" without any parameter pairs so here's how you do that:
$xml = '<?xml version="1.0"?><stuff><child>foo</child><child>bar</child></stuff>';
$httpRequest = curl_init();
curl_setopt($httpRequest, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($httpRequest, CURLOPT_HTTPHEADER, array("Content-Type: text/xml"));
curl_setopt($httpRequest, CURLOPT_POST, 1);
curl_setopt($httpRequest, CURLOPT_HEADER, 1);
curl_setopt($httpRequest, CURLOPT_URL, $url);
curl_setopt($httpRequest, CURLOPT_POSTFIELDS, $xml);
$returnHeader = curl_exec($httpRequest);
curl_close($httpRequest);
In my case, I needed to parse some values out of the HTTP response header so you may not necessarily need to set CURLOPT_RETURNTRANSFER
or CURLOPT_HEADER
.

I based this on @asawyer's answer. He doesn't seem to get a compile error, but some of us do. Here is a version which the C# compiler in Visual Studio 2010 will accept.
var timer = new System.Threading.Timer(
e => MyMethod(),
null,
TimeSpan.Zero,
TimeSpan.FromMinutes(5));
You can use find_all
in the following way to find every a
element that has an href
attribute, and print each one:
from BeautifulSoup import BeautifulSoup
html = '''<a href="some_url">next</a>
<span class="class"><a href="another_url">later</a></span>'''
soup = BeautifulSoup(html)
for a in soup.find_all('a', href=True):
print "Found the URL:", a['href']
The output would be:
Found the URL: some_url
Found the URL: another_url
Note that if you're using an older version of BeautifulSoup (before version 4) the name of this method is findAll
. In version 4, BeautifulSoup's method names were changed to be PEP 8 compliant, so you should use find_all
instead.
If you want all tags with an href
, you can omit the name
parameter:
href_tags = soup.find_all(href=True)
To be short, in React, there's no two-way data-binding.
So when you want to implement that feature, try define a state
, and write like this, listening events, update the state, and React renders for you:
class NameForm extends React.Component {
constructor(props) {
super(props);
this.state = {value: ''};
this.handleChange = this.handleChange.bind(this);
}
handleChange(event) {
this.setState({value: event.target.value});
}
render() {
return (
<input type="text" value={this.state.value} onChange={this.handleChange} />
);
}
}
Details here https://facebook.github.io/react/docs/forms.html
UPDATE 2020
Note:
LinkedStateMixin is deprecated as of React v15. The recommendation is to explicitly set the value and change handler, instead of using LinkedStateMixin.
above update from React official site . Use below code if you are running under v15 of React else don't.
There are actually people wanting to write with two-way binding, but React does not work in that way. If you do want to write like that, you have to use an addon for React, like this:
var WithLink = React.createClass({
mixins: [LinkedStateMixin],
getInitialState: function() {
return {message: 'Hello!'};
},
render: function() {
return <input type="text" valueLink={this.linkState('message')} />;
}
});
Details here https://facebook.github.io/react/docs/two-way-binding-helpers.html
For refs
, it's just a solution that allow developers to reach the DOM in methods of a component, see here https://facebook.github.io/react/docs/refs-and-the-dom.html
So you are doing this a bit backwards. Typically you'd do something like this:
?<div class='article'>
Article 1
</div>
<div class='article'>
Article 2
</div>
<div class='article'>
Article 3
</div>?
And then in your jQuery:
$('.article').click(function(){
article = $(this).text(); //$(this) is what you clicked!
});?
When I see things like #search-item .search-article
, #search-item .search-article
, and #search-item .search-article
I sense you are overspecifying your CSS which makes writing concise jQuery very difficult. This should be avoided if at all possible.

Assuming i'm in a container with 15px padding, this is what i always use for the inner part:
width:auto;
right:15px;
left:15px;
That will stretch the inner part to whatever width it should be less the 15px either side.
No.
Depending on your build environment (you don't specify), you may find that it works in exactly the way that you want.
However, there are many environments (both IDEs and a lot of hand crafted Makefiles) that expect to compile *.c - if that happens you will probably end up with linker errors due to duplicate symbols.
As a rule this practice should be avoided.
If you absolutely must #include source (and generally it should be avoided), use a different file suffix for the file.

I agree with Kevin and others, using a plugin for this is pointless.
window.scrollTo(0, $("#element").offset().top);
An alternative approach, which I've recently implemented, is to use the div-table plugin with panflute.
This creates a table from a set of fenced divs (standard in the pandoc implementation of markdown), in a similar layout to html:
---
panflute-filters: [div-table]
panflute-path: 'panflute/docs/source'
---
::::: {.divtable}
:::: {.tcaption}
a caption here (optional), only the first paragraph is used.
::::
:::: {.thead}
[Header 1]{width=0.4 align=center}
[Header 2]{width=0.6 align=default}
::::
:::: {.trow}
::: {.tcell}
1. any
2. normal markdown
3. can go in a cell
:::
::: {.tcell}
![](https://pixabay.com/get/e832b60e2cf7043ed1584d05fb0938c9bd22ffd41cb2144894f9c57aae/bird-1771435_1280.png?attachment){width=50%}
some text
:::
::::
:::: {.trow bypara=true}
If bypara=true
Then each paragraph will be treated as a separate column

any text outside a div will be ignored

Looks like:
One way is that In case of Session Expire, in every action you have to check its session and if it is null then redirect to Login page.
But this is very hectic method
To over come this you need to create your own ActionFilterAttribute
which will do this, you just need to add this attribute in every action method.
Here is the Class which overrides ActionFilterAttribute.
public class SessionExpireFilterAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
HttpContext ctx = HttpContext.Current;
// check if session is supported
CurrentCustomer objCurrentCustomer = new CurrentCustomer();
objCurrentCustomer = ((CurrentCustomer)SessionStore.GetSessionValue(SessionStore.Customer));
if (objCurrentCustomer == null)
{
// check if a new session id was generated
filterContext.Result = new RedirectResult("~/Users/Login");
return;
}
base.OnActionExecuting(filterContext);
}
}
Then in action just add this attribute like so:
[SessionExpire]
public ActionResult Index()
{
return Index();
}
This will do you work.
Numbers inherit from the Number
constructor which doesn't have the .toLowerCase
method. You can look it up as a matter of fact:
"toLowerCase" in Number.prototype; // false
A powerful option – and one which also boosts creativity – is designing your own characters using box drawing characters.
Want a down pointing "caret"? Here's one: ??
I've recently discovered them — and I take great pleasure at using such custom designed characters for labeling things all around :) .
$percentage = 50;
$totalWidth = 350;
$new_width = ($percentage / 100) * $totalWidth;
You need to add RouterMoudle

According to WWDC2015 Distribution Whats New
Setting "ITSAppUsesNonExemptEncryption" to "NO" in info.plist works fine. if no cryptographic content in your app.
I had got this pop up During selecting build for internal testing i didn't included "ITSAppUsesNonExemptEncryption" key in my info.plist but still worked for me.
Even i successfully uploaded new application didn't included "ITSEncryptionExportComplianceCode" and "ITSAppUsesNonExemptEncryption" keys.
Also Apple Doc.
Important: If your app requires that you provide additional documents for the encryption review, your app won’t have the Ready for Sale status on the store until Export Compliance has reviewed and approved your documents. The app can’t be distributed for prerelease testing until Export Compliance has reviewed and approved it.
If your app is not using encryption and you don’t want to have to answer these questions at the time of submission, you can provide export compliance information with your build. You can also provide new or updated documentation via iTunes Connect to receive the appropriate key string value to include with your build before uploading it to iTunes Connect.
To add export compliance documentation in iTunes Connect:
Go to the Encryption section under Features. Click the plus sign next to the appropriate platform section. Answer the questions appropriately. Attach the file when prompted. Click Save. Your documents will then be sent for review immediately and the status of your document will show in Compliance Review. A key value will also be generated automatically that you can include in your Info.plist file. For more information on including the key value with your build, see the Resources and Help section Trade Compliance.
You can upload a build without an export compliance key. If you include a key, it can indicate that you do not need export compliance documentation; this requires no approval. If you include a key that references a specific export compliance document, that document must be approved; it cannot be in In Review or Rejected.
You can review your answers at any time by clicking the document file name and selecting More Information. If you need to update your documentation or change any of the answers to the questions, you will need to repeat the steps above to add a new document that corresponds with your changes.
Here's a Java 7 solution that uses Guava's excellent support library and the try-with-resources construct. It reads and writes properties files using UTF-8 for the simplest overall experience.
To read a properties file as UTF-8:
File file = new File("/path/to/example.properties");
// Create an empty set of properties
Properties properties = new Properties();
if (file.exists()) {
// Use a UTF-8 reader from Guava
try (Reader reader = Files.newReader(file, Charsets.UTF_8)) {
properties.load(reader);
} catch (IOException e) {
// Do something
}
}
To write a properties file as UTF-8:
File file = new File("/path/to/example.properties");
// Use a UTF-8 writer from Guava
try (Writer writer = Files.newWriter(file, Charsets.UTF_8)) {
properties.store(writer, "Your title here");
writer.flush();
} catch (IOException e) {
// Do something
}
raw.github.com
is not truely raw access to file asset,
but a view rendered by Rails.
So accessing raw.github.com
is much heavier than needed.
I don't know why raw.github.com
is implemented as a Rails view.
Instead of fix this route issue, GitHub added a X-Content-Type-Options: nosniff
header.
Workaround:
user.github.io/repo
Use this:
void double_to_char(double f,char * buffer){
gcvt(f,10,buffer);
}
In my case same error is there , I am using Asyanc / Await functions , for this needs to add AWAIT for findOne
Ex:const foundUser = User.findOne ({ "email" : req.body.email });
above , foundUser always contains Object value in both cases either user found or not because it's returning values before finishing findOne .
const foundUser = await User.findOne ({ "email" : req.body.email });
above , foundUser returns null if user is not there in collection with provided condition . If user found returns user document.
Define an action:
const RESET_ACTION = {
type: "RESET"
}
Then in each of your reducers assuming you are using switch
or if-else
for handling multiple actions through each reducer. I am going to take the case for a switch
.
const INITIAL_STATE = {
loggedIn: true
}
const randomReducer = (state=INITIAL_STATE, action) {
switch(action.type) {
case 'SOME_ACTION_TYPE':
//do something with it
case "RESET":
return INITIAL_STATE; //Always return the initial state
default:
return state;
}
}
This way whenever you call RESET
action, you reducer will update the store with default state.
Now, for logout you can handle the like below:
const logoutHandler = () => {
store.dispatch(RESET_ACTION)
// Also the custom logic like for the rest of the logout handler
}
Every time a userlogs in, without a browser refresh. Store will always be at default.
store.dispatch(RESET_ACTION)
just elaborates the idea. You will most likely have an action creator for the purpose. A much better way will be that you have a LOGOUT_ACTION
.
Once you dispatch this LOGOUT_ACTION
. A custom middleware can then intercept this action, either with Redux-Saga or Redux-Thunk. Both ways however, you can dispatch another action 'RESET'. This way store logout and reset will happen synchronously and your store will ready for another user login.
You should use setTimestamp instead, if you hardcode it:
$start_date = new DateTime();
$start_date->setTimestamp(1372622987);
in your case
$start_date = new DateTime();
$start_date->setTimestamp($dbResult->db_timestamp);
You can use:
Resources.getSystem().getString(android.R.string.somecommonstuff)
... everywhere in your application, even in static constants declarations. Unfortunately, it supports the system resources only.
For local resources use this solution. It is not trivial, but it works.
In a nutshell, the syntax for Bower version numbers (and NPM's) is called SemVer, which is short for 'Semantic Versioning'. You can find documentation for the detailed syntax of SemVer as used in Bower and NPM on the API for the semver parser within Node/npm. You can learn more about the underlying spec (which does not mention ~
or other syntax details) at semver.org.
There's a super-handy visual semver calculator you can play with, making all of this much easier to grok and test.
SemVer isn't just a syntax! It has some pretty interesting things to say about the right ways to publish API's, which will help to understand what the syntax means. Crucially:
Once you identify your public API, you communicate changes to it with specific increments to your version number. Consider a version format of X.Y.Z (Major.Minor.Patch). Bug fixes not affecting the API increment the patch version, backwards compatible API additions/changes increment the minor version, and backwards incompatible API changes increment the major version.
So, your specific question about ~
relates to that Major.Minor.Patch schema. (As does the related caret operator ^
.) You can use ~
to narrow the range of versions you're willing to accept to either:
For example: to indicate you'll take any subsequent patch-level changes on the 1.2.x tree, starting with 1.2.0, but less than 1.3.0, you could use:
"angular": "~1.2"
or:
"angular": "~1.2.0"
This also gets you the same results as using the .x
syntax:
"angular": "1.2.x"
But, you can use the tilde/~
syntax to be even more specific: if you're only willing to accept patch-level changes starting with 1.2.4, but still less than 1.3.0, you'd use:
"angular": "~1.2.4"
Moving left, towards the major version, if you use...
"angular": "~1"
... it's the same as...
"angular": "1.x"
or:
"angular": "^1.0.0"
...and matches any minor- or patch-level changes above 1.0.0, and less than 2.0:
Note that last variation above: it's called a 'caret range'. The caret looks an awful lot like a >
, so you'd be excused for thinking it means "any version greater than 1.0.0". (I've certainly slipped on that.) Nope!
Caret ranges are basically used to say that you care only about the left-most significant digit - usually the major version - and that you'll permit any minor- or patch-level changes that don't affect that left-most digit. Yet, unlike a tilde range that specifies a major version, caret ranges let you specify a precise minor/patch starting point. So, while ^1.0.0 === ~1
, a caret range such as ^1.2.3
lets you say you'll take any changes >=1.2.3 && <2.0.0
. You couldn't do that with a tilde range.
That all seems confusing at first, when you look at it up-close. But zoom out for a sec, and think about it this way: the caret simply lets you say that you're most concerned about whatever significant digit is left-most. The tilde lets you say you're most concerned about whichever digit is right-most. The rest is detail.
It's the expressive power of the tilde and the caret that explains why people use them much more than the simpler .x
syntax: they simply let you do more. That's why you'll see the tilde used often even where .x
would serve. As an example, see npm itself: its own package.json file includes lots of dependencies in ~2.4.0
format, rather than the 2.4.x
format it could use. By sticking to ~
, the syntax is consistent all the way down a list of 70+ versioned dependencies, regardless of which beginning patch number is acceptable.
Anyway, there's still more to SemVer, but I won't try to detail it all here. Check it out on the node semver package's readme. And be sure to use the semantic versioning calculator while you're practicing and trying to get your head around how SemVer works.
RE: Non-Consecutive Version Numbers: OP's final question seems to be about specifying non-consecutive version numbers/ranges (if I have edited it fairly). Yes, you can do that, using the common double-pipe "or" operator: ||
. Like so:
"angular": "1.2 <= 1.2.9 || >2.0.0"
It is actually a permission issue. Add these lines in your platforms/android/AndroidManifest.xml

I write my answer in Python 2.7:
In Python, method overloading is not possible; if you really want access the same function with different features, I suggest you to go for method overriding.
class Base(): # Base class
'''def add(self,a,b):
s=a+b
print s'''
def add(self,a,b,c):
self.a=a
self.b=b
self.c=c
sum =a+b+c
print sum
class Derived(Base): # Derived class
def add(self,a,b): # overriding method
sum=a+b
print sum
add_fun_1=Base() #instance creation for Base class
add_fun_2=Derived()#instance creation for Derived class
add_fun_1.add(4,2,5) # function with 3 arguments
add_fun_2.add(4,2) # function with 2 arguments

There's a great example here:
https://kb.novaordis.com/index.php/Gradle_Pass_Configuration_on_Command_Line
Which details that you can pass parameters and then provide a default in an ext variable like so:
gradle -Dmy_app.color=blue
and then reference in Gradle as:
ext {
color = System.getProperty("my_app.color", "red");
}
And then anywhere in your build script you can reference it as course anywhere you can reference it as project.ext.color

Uses a "standard" set of character orderings (a,b,c, ... etc.). This is in contrast to some specific locales, which may sort characters in different orders ('a-with-acute' may be before or after 'a', depending on the locale, and so on).
On the other hand, looks purely at the values of the raw byte(s) that represent the character.
There's a great sample at http://msdn.microsoft.com/en-us/library/e6883c06.aspx that shows the results of the various StringComparison values. All the way at the end, it shows (excerpted):
StringComparison.InvariantCulture:
LATIN SMALL LETTER I (U+0069) is less than LATIN SMALL LETTER DOTLESS I (U+0131)
LATIN SMALL LETTER I (U+0069) is less than LATIN CAPITAL LETTER I (U+0049)
LATIN SMALL LETTER DOTLESS I (U+0131) is greater than LATIN CAPITAL LETTER I (U+0049)
StringComparison.Ordinal:
LATIN SMALL LETTER I (U+0069) is less than LATIN SMALL LETTER DOTLESS I (U+0131)
LATIN SMALL LETTER I (U+0069) is greater than LATIN CAPITAL LETTER I (U+0049)
LATIN SMALL LETTER DOTLESS I (U+0131) is greater than LATIN CAPITAL LETTER I (U+0049)
You can see that where InvariantCulture yields (U+0069, U+0049, U+00131), Ordinal yields (U+0049, U+0069, U+00131).
In versions of jQuery before 1.6 use:
$('input[name="correctAnswer"]').attr('checked', false);
In versions of jQuery after 1.6 you should use:
$('input[name="correctAnswer"]').prop('checked', false);
but if you are using 1.6.1+ you can use the first form (see note 2 below).
Note 1: it is important that the second argument be false and not "false" since "false" is not a falsy value. i.e.
if ("false") {
alert("Truthy value. You will see an alert");
}
Note 2: As of jQuery 1.6.0, there are now two similar methods, .attr
and .prop
that do two related but slightly different things. If in this particular case, the advice provide above works if you use 1.6.1+. The above will not work with 1.6.0, if you are using 1.6.0, you should upgrade. If you want the details, keep reading.
Details: When working with straight HTML DOM elements, there are properties attached to the DOM element (checked
, type
, value
, etc) which provide an interface to the running state of the HTML page. There is also the .getAttribute
/.setAttribute
interface which provides access to the HTML Attribute values as provided in the HTML. Before 1.6 jQuery blurred the distinction by providing one method, .attr
, to access both types of values. jQuery 1.6+ provides two methods, .attr
and .prop
to get distinguish between these situations.
.prop
allows you to set a property on a DOM element, while .attr
allows you to set an HTML attribute value. If you are working with plain DOM and set the checked property, elem.checked
, to true
or false
you change the running value (what the user sees) and the value returned tracks the on page state. elem.getAttribute('checked')
however only returns the initial state (and returns 'checked'
or undefined
depending on the initial state from the HTML). In 1.6.1+ using .attr('checked', false)
does both elem.removeAttribute('checked')
and elem.checked = false
since the change caused a lot of backwards compatibility issues and it can't really tell if you wanted to set the HTML attribute or the DOM property. See more information in the documentation for .prop.
As per this answer:
TimeZone tz = TimeZone.getTimeZone("EST");

$ git fetch upstream

You could just change this:
`create_date` TIMESTAMP NOT NULL DEFAULT '0000-00-00 00:00:00',
To something like this:
`create_date` TIMESTAMP NOT NULL DEFAULT '2018-04-01 12:00:00',
An alternative approach would be:
df1 = sqlContext.createDataFrame(
[(1, "a", 2.0), (2, "b", 3.0), (3, "c", 3.0)],
("x1", "x2", "x3"))
df2 = sqlContext.createDataFrame(
[(1, "f", -1.0), (2, "b", 0.0)], ("x1", "x2", "x4"))
df = df1.join(df2, ['x1','x2'])
df.show()
which outputs:
+---+---+---+---+
| x1| x2| x3| x4|
+---+---+---+---+
| 2| b|3.0|0.0|
+---+---+---+---+
With the main advantage being that the columns on which the tables are joined are not duplicated in the output, reducing the risk of encountering errors such as org.apache.spark.sql.AnalysisException: Reference 'x1' is ambiguous, could be: x1#50L, x1#57L.
Whenever the columns in the two tables have different names, (let's say in the example above, df2
has the columns y1
, y2
and y4
), you could use the following syntax:
df = df1.join(df2.withColumnRenamed('y1','x1').withColumnRenamed('y2','x2'), ['x1','x2'])
In SQL Server:
SELECT LEN(REPLACE(myColumn, 'N', ''))
FROM ...
Try this one:
try
{
device_version = getPackageManager().getPackageInfo("com.google.android.gms", 0).versionName;
}
catch (PackageManager.NameNotFoundException e)
{
e.printStackTrace();
}
To add to the good answer by @Tomalak:
Here are some unmentioned and important differences:
xsl:apply-templates
is much richer and deeper than xsl:call-templates
and even from xsl:for-each
, simply because we don't know what code will be applied on the nodes of
the selection -- in the general case this code will be different for
different nodes of the node-list.
The code that will be applied
can be written way after the xsl:apply template
s was written and by
people that do not know the original author.
The FXSL library's implementation of higher-order functions (HOF) in XSLT wouldn't be possible if XSLT didn't have the <xsl:apply-templates>
instruction.
Summary: Templates and the <xsl:apply-templates>
instruction is how XSLT implements and deals with polymorphism.
Reference: See this whole thread: http://www.biglist.com/lists/lists.mulberrytech.com/xsl-list/archives/200411/msg00546.html
One important fact about NVIDIA drivers that is not very well known is that its built is done by DKMS. This allows automatic rebuild in case of kernel upgrade, this happens on system startup. Because of that, it's quite easy to miss error messages, especially if you're working on cloud VM, or server without an additional IPMI/management interface. However, it's possible to trigger DKMS build just executing dkms autoinstall
right after packages installation. If this fails then you'll have a meaningful error message about missing dependency or what so ever. If dkms autoinstall
builds modules correctly you can simply load it by modprobe
- there is no need to reboot the system (which is often used as a way to trigger DKMS rebuild).

I feel like I should add my answer to this because it took me quite long to make this work:
This answer is for you if:
bquote

n <- 10
x <- seq(0, 300, length.out = n)
# I have my data in a "long" format
my_data <- data.frame(
Type = as.factor(c(rep('dl/l', n), rep('alpha', n))),
T = c(x, x),
Value = c(x*0.1, sqrt(x))
)
# the label names as a named vector
type_names <- c(
`nonsense` = "this is just here because it looks good",

About prototype bean(s) :
The client code must clean up prototype-scoped objects and release expensive resources that the prototype bean(s) are holding. To get the Spring container to release resources held by prototype-scoped beans, try using a custom bean post-processor, which holds a reference to beans that need to be cleaned up.
You can't stop a timer function mid-execution. You can only catch it after it completes and prevent it from triggering again.
Here's a solution that doesn't use JS at all. It uses checkboxes instead.
You can hide the checkbox by adding this to your CSS:
.container input{
display: none;
}
And then add some styling to make it look like a button.
I think you've missed the point of access control.
A quick recap on why CORS exists: Since JS code from a website can execute XHR, that site could potentially send requests to other sites, masquerading as you and exploiting the trust those sites have in you(e.g. if you have logged in, a malicious site could attempt to extract information or execute actions you never wanted) - this is called a CSRF attack. To prevent that, web browsers have very stringent limitations on what XHR you can send - you are generally limited to just your domain, and so on.
Now, sometimes it's useful for a site to allow other sites to contact it - sites that provide APIs or services, like the one you're trying to access, would be prime candidates. CORS was developed to allow site A(e.g. paste.ee
) to say "I trust site B, so you can send XHR from it to me". This is specified by site A sending "Access-Control-Allow-Origin" headers in its responses.
In your specific case, it seems that paste.ee
doesn't bother to use CORS. Your best bet is to contact the site owner and find out why, if you want to use paste.ee with a browser script. Alternatively, you could try using an extension(those should have higher XHR privileges).
45 characters.
You might expect an address to be
0000:0000:0000:0000:0000:0000:0000:0000
8 * 4 + 7 = 39
8 groups of 4 digits with 7 :
between them.
But if you have an IPv4-mapped IPv6 address, the last two groups can be written in base 10 separated by .
, eg. [::ffff:192.168.100.228]
. Written out fully:
0000:0000:0000:0000:0000:ffff:192.168.100.228
(6 * 4 + 5) + 1 + (4 * 3 + 3) = 29 + 1 + 15 = 45
Note, this is an input/display convention - it's still a 128 bit address and for storage it would probably be best to standardise on the raw colon separated format, i.e. [0000:0000:0000:0000:0000:ffff:c0a8:64e4]
for the address above.
Example of a Boolean (AND) plus Wildcard search, which I'm using inside a javascript Autocomplete plugin:
String to match: "my word"
String to search: "I'm searching for my funny words inside this text"
You need the following regex: /^(?=.*my)(?=.*word).*$/im
Explaining:
^ assert position at start of a line
?= Positive Lookahead
.* matches any character (except newline)
() Groups
$ assert position at end of a line
i modifier: insensitive. Case insensitive match (ignores case of [a-zA-Z])
m modifier: multi-line. Causes ^ and $ to match the begin/end of each line (not only begin/end of string)
Test the Regex here: https://regex101.com/r/iS5jJ3/1
So, you can create a javascript function that:
Example:
function fullTextCompare(myWords, toMatch){_x000D_
//Replace regex reserved characters_x000D_
myWords=myWords.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');_x000D_
//Split your string at spaces_x000D_
arrWords = myWords.split(" ");_x000D_
//Encapsulate your words inside regex groups_x000D_
arrWords = arrWords.map(function( n ) {_x000D_
return ["(?=.*"+n+")"];_x000D_
});_x000D_
//Create a regex pattern_x000D_
sRegex = new RegExp("^"+arrWords.join("")+".*$","im");_x000D_
//Execute the regex match_x000D_
return(toMatch.match(sRegex)===null?false:true);_x000D_
}_x000D_
_x000D_
//Using it:_x000D_
console.log(_x000D_
fullTextCompare("my word","I'm searching for my funny words inside this text")_x000D_
);_x000D_
_x000D_
//Wildcards:_x000D_
console.log(_x000D_
fullTextCompare("y wo","I'm searching for my funny words inside this text")_x000D_
);
_x000D_
Wait -- did you actually mean that "the same number of rows ... are being processed" or that "the same number of rows are being returned"? In general, the outer join would process many more rows, including those for which there is no match, even if it returns the same number of records.
I had the same problem: the latest update failed to install because it couldn't rename the tools folder in android-sdk-windows. I'm using AVG antivirus and disabling it didn't help, but I don't think it had anything to do with the AV program anyway.
Fact is, running the Android SDK setup apparently uses items in the "android-sdk-windows\tools" directory. I'm on Win Vista x32 so maybe that causes some unique situation - I'm not sure.
Solution:
I made a copy of the tools folder itself (keeping it at the same directory tree level, thus "tools" and "tools-copy" were both in the "android-sdk-windows" folder).
I ran Android.bat from that copy
I ran the update without problems (it updated the original, not-being-used-at-the-moment tools folder, among whatever other items it needed to).
I closed the SDK, deleted the folder (I had to kill the adb.exe process first - not sure why that always persists but you can't delete the folder without doing that).
I restarted the SDK from the normal (now-updated) tools folder. Worked like a charm!
Note that simply killing adb.exe was NOT sufficient to get around the original issue... only by copying the tools folder and using the copy to run Android for the duration of the update process was enough to rectify the problem.
I hope this helps others... it's quite vexing to have to spend time resolving basic issues like this just to run an update.
Old question I know, but this is now possible using the css property table-layout: fixed
on the table tag. Answer below from this question CSS percentage width and text-overflow in a table cell
This is easily done by using table-layout: fixed
, but a little tricky because not many people know about this CSS property.
table {
width: 100%;
table-layout: fixed;
}
See it in action at the updated fiddle here: http://jsfiddle.net/Fm5bM/4/
I asume you have connected to your database already.
$sql = "SELECT * FROM my_table";
$result = mysql_query($sql);
$row = 1; // 1-based index
while($row_data = mysql_fetch_assoc($result)) {
$col = 0;
foreach($row_data as $key=>$value) {
$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);
$col++;
}
$row++;
}
Maybe too late, but I'd cast 0/1 as bit to make the datatype eventually becomes True/False when consumed by .NET framework:
SELECT EntityId,
EntityName,
CASE
WHEN EntityProfileIs IS NULL
THEN CAST(0 as bit)
ELSE CAST(1 as bit) END AS HasProfile
FROM Entities
LEFT JOIN EntityProfiles ON EntityProfiles.EntityId = Entities.EntityId`

I think you can use db.collection.distinct(fields,query)
You will be able to get the distinct values in your case for NetworkID.
It should be something like this :
Db.collection.distinct('NetworkID')
A Compiler translates lines of code from the programming language into machine language.
A Linker creates a link between two programs.
A Loader loads the program into memory in the main database, program, etc.
Actually a more refined solution is use the build-in function sumif, this function does exactly what you need, will only sum those expenses of a specified month.
example
=SUMIF(A2:A100,"=January",B2:B100)
My solution for changing seconds (number) to string format (for example: 'mm:ss'):
const formattedSeconds = moment().startOf('day').seconds(S).format('mm:ss');
Write your seconds instead 'S' in example. And just use the 'formattedSeconds' where you need.
Declare them outside the subroutines, like this:
Public wbA as Workbook
Public wbB as Workbook
Sub MySubRoutine()
Set wbA = Workbooks.Open("C:\file.xlsx")
Set wbB = Workbooks.Open("C:\file2.xlsx")
OtherSubRoutine
End Sub
Sub OtherSubRoutine()
MsgBox wbA.Name, vbInformation
End Sub
Alternately, you can pass variables between subroutines:
Sub MySubRoutine()
Dim wbA as Workbook
Dim wbB as Workbook
Set wbA = Workbooks.Open("C:\file.xlsx")
Set wbB = Workbooks.Open("C:\file2.xlsx")
OtherSubRoutine wbA, wbB
End Sub
Sub OtherSubRoutine(wb1 as Workbook, wb2 as Workbook)
MsgBox wb1.Name, vbInformation
MsgBox wb2.Name, vbInformation
End Sub
Or use Functions
to return values:
Sub MySubroutine()
Dim i as Long
i = MyFunction()
MsgBox i
End Sub
Function MyFunction()
'Lots of code that does something
Dim x As Integer, y as Double
For x = 1 to 1000
'Lots of code that does something
Next
MyFunction = y
End Function
In the second method, within the scope of OtherSubRoutine
you refer to them by their parameter names wb1
and wb2
. Passed variables do not need to use the same names, just the same variable types. This allows you some freedom, for example you have a loop over several workbooks, and you can send each workbook to a subroutine to perform some action on that Workbook, without making all (or any) of the variables public in scope.
A Note About User Forms
Personally I would recommend keeping Option Explicit
in all of your modules and forms (this prevents you from instantiating variables with typos in their names, like lCoutn
when you meant lCount
etc., among other reasons).
If you're using Option Explicit
(which you should), then you should qualify module-scoped variables for style and to avoid ambiguity, and you must qualify user-form Public
scoped variables, as these are not "public" in the same sense. For instance, i
is undefined, though it's Public
in the scope of UserForm1
:
You can refer to it as UserForm1.i
to avoid the compile error, or since forms are New
-able, you can create a variable object to contain reference to your form, and refer to it that way:
NB: In the above screenshots x
is declared Public x as Long
in another standard code module, and will not raise the compilation error. It may be preferable to refer to this as Module2.x
to avoid ambiguity and possible shadowing in case you re-use variable names...
Whenever I run CodeIgniter in a sub directory I set the RewriteBase
to it. Try setting it as /myproj/
instead of /
.
To fix this issue in Web.config I just had to add debug="true"
<system.web>
<compilation targetFramework="4.0" debug="true">
What helped me to find this solution has been looking at the Modules windows while debugging and saw that for my ASP.NET DLLs loaded I had: Binary was not built with debug information.
You need to use RegularExpression Attribute, something like this:
[RegularExpression("^[a-zA-Z0-9_\\.-]+@([a-zA-Z0-9-]+\\.)+[a-zA-Z]{2,6}$", ErrorMessage = "E-mail is not valid")]
And don't delete [Required] because [RegularExpression] doesn't affect empty fields.
Please try this which it works for me.

Use OrderedDicts: http://docs.python.org/2/library/collections.html#collections.OrderedDict
>>> x = OrderedDict((("a", "1"), ("c", '3'), ("b", "2")))
>>> x["d"] = 4
>>> x.keys().index("d")
3
>>> x.keys().index("c")
1
For those using Python 3
>>> list(x.keys()).index("c")
1
If you have an array, a
of say 210 rows by 8 columns:
a = numpy.empty([210,8])
and want to add a ninth column of zeros you can do this:
b = numpy.append(a,numpy.zeros([len(a),1]),1)
PHP regex strings need delimiters. Try:
$numpattern="/^([0-9]+)$/";
Also, note that you have a lower case o, not a zero. In addition, if you're just validating, you don't need the capturing group, and can simplify the regex to /^\d+$/
.
Example: http://ideone.com/Ec3zh

I like this approach
my_hash = {}
my_hash["goals"] = 3 #to show number
my_hash["penalties"] = "5" #to show string
print("I scored %(goals)d goals and took %(penalties)s penalties" % my_hash)
Note the appended d and s to the brackets respectively.
output will be:
I scored 3 goals and took 5 penalties
You might also try giving the full path to the binary you're trying to run. That solved my problem when trying to use ImageMagick
.
I have jus implement this library:https://github.com/jose78/go-collection. This is an example about how to use the Foreach loop:
package main
import (
"fmt"
col "github.com/jose78/go-collection/collections"
)
type user struct {
name string
age int
id int
}
func main() {
newList := col.ListType{user{"Alvaro", 6, 1}, user{"Sofia", 3, 2}}
newList = append(newList, user{"Mon", 0, 3})
newList.Foreach(simpleLoop)
if err := newList.Foreach(simpleLoopWithError); err != nil{
fmt.Printf("This error >>> %v <<< was produced", err )
}
}
var simpleLoop col.FnForeachList = func(mapper interface{}, index int) {
fmt.Printf("%d.- item:%v\n", index, mapper)
}
var simpleLoopWithError col.FnForeachList = func(mapper interface{}, index int) {
if index > 1{
panic(fmt.Sprintf("Error produced with index == %d\n", index))
}
fmt.Printf("%d.- item:%v\n", index, mapper)
}
The result of this execution should be:
0.- item:{Alvaro 6 1}
1.- item:{Sofia 3 2}
2.- item:{Mon 0 3}
0.- item:{Alvaro 6 1}
1.- item:{Sofia 3 2}
Recovered in f Error produced with index == 2
ERROR: Error produced with index == 2
This error >>> Error produced with index == 2
<<< was produced
when: myvar | default('', true) | trim != ''
I use | trim != ''
to check if a variable has an empty value or not. I also always add the | default(..., true)
check to catch when myvar
is undefined too.
download rpm packages and run the following command:
rpm -Uvh glibc-2.15-60.el6.x86_64.rpm \
glibc-common-2.15-60.el6.x86_64.rpm \
glibc-devel-2.15-60.el6.x86_64.rpm \
glibc-headers-2.15-60.el6.x86_64.rpm
For me it works like this
Rotate clockwise
ffmpeg -i "path_source_video.mp4" -filter:v "transpose=1" "path_output_video.mp4"
Rotate counterclockwise
ffmpeg -i "path_source_video.mp4" -filter:v "transpose=0,transpose=1,transpose=0" -acodec copy "path_output_video.mp4"
the package I use zeranoe
You can use the statement :-
Class c = s.getClass();
To get the class instance.
Your svn merge
syntax is wrong.
You want to checkout a working copy of trunk
and then use the svn merge --reintegrate
option:
$ pwd
/home/user/project-trunk
$ svn update # (make sure the working copy is up to date)
At revision <N>.
$ svn merge --reintegrate ^/project/branches/branch_1
--- Merging differences between repository URLs into '.':
U foo.c
U bar.c
U .
$ # build, test, verify, ...
$ svn commit -m "Merge branch_1 back into trunk!"
Sending .
Sending foo.c
Sending bar.c
Transmitting file data ..
Committed revision <N+1>.
See the SVN book chapter on merging for more details.
Note that at the time it was written, this was the right answer (and was accepted), but things have moved on. See the answer of topek, and http://subversion.apache.org/docs/release-notes/1.8.html#auto-reintegrate
