This can be done fairly easily with SyntaxHighlighter. I have step-by-step instructions for setting up SyntaxHighlighter in Blogger on my blog. SyntaxHighlighter is very easy to use. It lets you post snippets in raw form and then wrap them in pre
blocks like:
<pre name="code" class="brush: erlang"><![CDATA[
-module(trim).
-export([string_strip_right/1, reverse_tl_reverse/1, bench/0]).
bench() -> [nbench(N) || N <- [1,1000,1000000]].
nbench(N) -> {N, bench(["a" || _ <- lists:seq(1,N)])}.
bench(String) ->
{{string_strip_right,
lists:sum([
element(1, timer:tc(trim, string_strip_right, [String]))
|| _ <- lists:seq(1,1000)])},
{reverse_tl_reverse,
lists:sum([
element(1, timer:tc(trim, reverse_tl_reverse, [String]))
|| _ <- lists:seq(1,1000)])}}.
string_strip_right(String) -> string:strip(String, right, $\n).
reverse_tl_reverse(String) ->
lists:reverse(tl(lists:reverse(String))).
]]></pre>
Just change the brush name to "python" or "java" or "javascript" and paste in the code of your choice. The CDATA tagging let's you put pretty much any code in there without worrying about entity escaping or other typical annoyances of code blogging.
If you want to achieve this just keep you dropdown button and style it like the select box. The code is here and below.
.btn {
cursor: default;
background-color: #FFF;
border-radius: 4px;
text-align: left;
}
.caret {
position: absolute;
right: 16px;
top: 16px;
}
.btn-default:hover, .btn-default:focus, .btn-default:active, .btn-default.active, .open .dropdown-toggle.btn-default {
background-color: #FFF;
}
.btn-group.open .dropdown-toggle {
box-shadow: 0 1px 1px rgba(0, 0, 0, 0.075) inset, 0 0 8px rgba(102, 175, 233, 0.6)
}
.btn-group {width: 100%}
.dropdown-menu {width: 100%;}
To make the button work like a select box, all you need to add is this tiny javascript code:
$('.dropdown-menu a').on('click', function(){
$('.dropdown-toggle').html($(this).html() + '<span class="caret"></span>');
})
If you have multiple custom dropdowns like this you can use this javascript code:
$('.dropdown-menu a').on('click', function(){
$(this).parent().parent().prev().html($(this).html() + '<span class="caret"></span>');
})
What about something like this.
<div id="movie_item">
<div class="movie_item_poster">
<img src="..." style="max-width: 100%; max-height: 100%;">
</div>
<div id="movie_item_content">
<div class="movie_item_content_year">year</div>
<div class="movie_item_content_title">title</div>
<div class="movie_item_content_plot">plot</div>
</div>
<div class="movie_item_toolbar">
Lorem Ipsum...
</div>
</div>
You don't have to float both movie_item_poster
AND movie_item_content
. Just float one of them...
#movie_item {
position: relative;
margin-top: 10px;
height: 175px;
}
.movie_item_poster {
float: left;
height: 150px;
width: 100px;
}
.movie_item_content {
position: relative;
}
.movie_item_content_title {
}
.movie_item_content_year {
float: right;
}
.movie_item_content_plot {
}
.movie_item_toolbar {
clear: both;
vertical-align: bottom;
width: 100%;
height: 25px;
}
Create a folder named fonts in the assets folder and add the snippet from the below link.

I've used Blat ( http://www.blat.net/ ) for many years. It's a simple command line utility that can send email from command line. It's free and opensource.
You can use command like "Blat myfile.txt -to [email protected] -server smtp.domain.com -port 6000"
Here is some other software you can try to send email from command line (I've never used them):
http://caspian.dotconf.net/menu/Software/SendEmail/
http://www.petri.co.il/sendmail.htm
http://www.petri.co.il/software/mailsend105.zip
http://retired.beyondlogic.org/solutions/cmdlinemail/cmdlinemail.htm
Here ( http://www.petri.co.il/send_mail_from_script.htm ) you can find other various way of sending email from a VBS script, plus link to some of the mentioned software
The following VBScript code is taken from that page
Set objEmail = CreateObject("CDO.Message")
objEmail.From = "[email protected]"
objEmail.To = "[email protected]"
objEmail.Subject = "Server is down!"
objEmail.Textbody = "Server100 is no longer accessible over the network."
objEmail.Send
Save the file as something.vbs
Set Msg = CreateObject("CDO.Message")
With Msg
.To = "[email protected]"
.From = "[email protected]"
.Subject = "Hello"
.TextBody = "Just wanted to say hi."
.Send
End With
Save the file as something2.vbs
I think these VBS scripts use the windows default mail server, if present. I've not tested these scripts...
<div class="row" *ngIf="teamMembers?.length > 0">
This checks first if teamMembers

because the first part of the condition already fails.
The correct answer (as of Dec 2018) is... you can't. Upgrading conda install python=3.6
may work, but it might not if you have packages that are necessary, but cannot be uninstalled.
Anaconda uses a default environment named base
and you cannot create a new (e.g. python 3.6) environment with the same name. This is intentional. If you want your base Anaconda to be python 3.6, the right way to do this is to install Anaconda for python 3.6. As a package manager, the goal of Anaconda is to make different environments encapsulated, hence why you must source activate into them and why you can't just quietly switch the base package at will as this could lead to many issues on production systems.
I use such kind of a Map population thanks to Java 9. In my honest opinion, this approach provides more readability to the code.
public static void main(String[] args) {
Map<Integer, Point2D.Double> map = Map.of(
1, new Point2D.Double(1, 1),
2, new Point2D.Double(2, 2),
3, new Point2D.Double(3, 3),
4, new Point2D.Double(4, 4));
map.entrySet().forEach(System.out::println);
}
I have used frames at my continuing education commercial site for over 15 years. Frames allow the navigation frame to load material into the main frame using the target feature while leaving the navigator frame untouched. Furthermore, Perl scripts operate quite well from a frame form returning the output to the same frame. I love frames and will continue using them. CSS is far too complicated for practical use. I have had no problems using frames with HTML5 with IE, Safari, Chrome, or Firefox.
I faced the same problem and .toString() worked for me. I'm using mongojs driver. Here was my question
You can create a getter and then override that getter. It's particularly useful if the variable you are overriding is a sub-class of itself. Imagine your super class has an Object
member but in your sub-class this is now more defined to be an Integer
.
class Dad
{
private static final String me = "dad";
protected String getMe() {
return me;
}
public void printMe()
{
System.out.println(getMe());
}
}
class Son extends Dad
{
private static final String me = "son";
@Override
protected String getMe() {
return me;
}
}
public void doIt()
{
new Son().printMe(); //Prints "son"
}
I solved similar problem this way:
@Component
public class DataLoader {
@Autowired
private UserRepository userRepository;
//method invoked during the startup
@PostConstruct
public void loadData() {
userRepository.save(new User("user"));
}
//method invoked during the shutdown
@PreDestroy
public void removeData() {
userRepository.deleteAll();
}
}
If you're doing some sort of math with the numbers you might also want to know the units. Given your input restrictions (that the input string contains unit and value only), this should correctly return both (you'll just need to figure out how to convert units into common units for your math).
def unit_value(str):
m = re.match(r'([^\d]*)(\d*\.?\d+)([^\d]*)', str)
if m:
g = m.groups()
return ' '.join((g[0], g[2])).strip(), float(g[1])
else:
return int(str)
Or try the Ruby 1.9 way:
array.inject(0, :+)
Note: the 0
base case is needed otherwise nil
will be returned on empty arrays:
> [].inject(:+)
nil
> [].inject(0, :+)
0
.set_title('') can be used to add title to Seaborn Plot

Google's libs-for-android has a nice libraries for managing image and file cache.
In python the with
keyword is used when working with unmanaged resources (like file streams). It is similar to the using
statement in VB.NET and C#. It allows you to ensure that a resource is "cleaned up" when the code that uses it finishes running, even if exceptions are thrown. It provides 'syntactic sugar' for try/finally
blocks.
From Python Docs:
The
with
statement clarifies code that previously would usetry...finally
blocks to ensure that clean-up code is executed. In this section, I’ll discuss the statement as it will commonly be used. In the next section, I’ll examine the implementation details and show how to write objects for use with this statement.The
with
statement is a control-flow structure whose basic structure is:with expression [as variable]: with-block
The expression is evaluated, and it should result in an object that supports the context management protocol (that is, has
__enter__()
and__exit__()
methods).
Update fixed VB callout per Scott Wisniewski's comment. I was indeed confusing with
with using
.
the approved answer does not include the essential return false to prevent touchstart from calling click if click is implemented which will result in running the handler twoce.
do:
$(btn).on('click touchstart', e => {

});
A good resource start off point would be MSDN as your looking into a microsoft product
From my looking you give a null value to a textbox and return in a ToString()
as it is a static method. You can replace it with Convert.ToString()
that can enable null value.

Depending on how complicated your regular expression is, you could possibly just use simple string slicing. I'm not sure about the practicality of this for your application or whether or not it would actually offer any speed improvements.
'testsentence'['stsen']

Well I think you just need to add a quantifier to each pattern. Also the carriage-return thing is a little funny:
text.replace(/[^a-z0-9]+|\s+/gmi, " ");
edit The \s
thing matches \r
and \n
too.
Like this:
$(this).data('id');
$(this).data('option');

I just created a jQuery function to load an image using jQuerys Deferred Object which makes it very easy to react on load/error event:
$.fn.extend({
loadImg: function(url, timeout) {
// init deferred object
var defer = $.Deferred(),
$img = this,
img = $img.get(0),
timer = null;
// define load and error events BEFORE setting the src
// otherwise IE might fire the event before listening to it
$img.load(function(e) {
var that = this;
// defer this check in order to let IE catch the right image size
window.setTimeout(function() {
// make sure the width and height are > 0
((that.width > 0 && that.height > 0) ?
defer.resolveWith :
defer.rejectWith)($img);
}, 1);
}).error(function(e) {
defer.rejectWith($img);
});
// start loading the image
img.src = url;
// check if it's already in the cache
if (img.complete) {
defer.resolveWith($img);
} else if (0 !== timeout) {
// add a timeout, by default 15 seconds
timer = window.setTimeout(function() {
defer.rejectWith($img);
}, timeout || 15000);
}
// return the promise of the deferred object
return defer.promise().always(function() {
// stop the timeout timer
window.clearTimeout(timer);
timer = null;
// unbind the load and error event
this.off("load error");
});
}
});
Usage:
var image = $('<img />').loadImg('http://www.google.com/intl/en_com/images/srpr/logo3w.png')
.done(function() {
alert('image loaded');
$('body').append(this);
}).fail(function(){
alert('image failed');
});

I've had this problem too, I had just forgotten to type workon myproject in the terminal before executing my program.
Maven is trying to download m2e's lifecycle-mapping artifact, which M2E uses to determine how to process plugins within Eclipse (adding source folders, etc.). For some reason this artifact cannot be downloaded. Do you have an internet connection? Can other artifacts be downloaded from repositories? Proxy settings?
For more details from Maven, try turning M2E debug output on (Settings/Maven/Debug Output checkbox) and it might give you more details as to why it cannot download from the repository.
I had this problem, and the cause was rather silly. I was trying out Microsoft's demo regarding running a ServiceHost from w/in a Command Line executable. I followed the instructions, including where it says to add the appropriate Service (and interface). But I got the above error.
Turns out when I added the service class, VS automatically added the configuration to the app.config. And the demo was trying to add that info too. Since it was already in the config, I removed the demo part, and it worked.
Reducing the image size before output results in something that looks sharper, in my case:
convert -density 300 a.pdf -resize 25% a.png
I think I've finally got it!

import weakref
class InsaneClass(object):
_alive = []
def __new__(cls):
self = super().__new__(cls)
InsaneClass._alive.append(self)
return weakref.proxy(self)
def commit_suicide(self):
self._alive.remove(self)
instance = InsaneClass()
instance.commit_suicide()
print(instance)
# Raises Error: ReferenceError: weakly-referenced object no longer exists
When the object is created in the __new__
method, the instance is replaced by a weak reference proxy and the only strong reference is kept in the _alive class attribute.
Weak-reference is a reference which does not count as a reference when the garbage collector collects the object. Consider this example:
>>> class Test(): pass
>>> a = Test()
>>> b = Test()
>>> c = a
>>> d = weakref.proxy(b)
>>> d
<weakproxy at 0x10671ae58 to Test at 0x10670f4e0>
# The weak reference points to the Test() object
>>> del a
>>> c
<__main__.Test object at 0x10670f390> # c still exists
>>> del b
>>> d
<weakproxy at 0x10671ab38 to NoneType at 0x1002050d0>
# d is now only a weak-reference to None. The Test() instance was garbage-collected
So the only strong reference to the instance is stored in the _alive class attribute. And when the commit_suicide() method removes the reference the instance is garbage-collected.

The getElementById()
based method in the selected answer won't work if the anchor has name
but not id
set (which is not recommended, but does happen in the wild).
Something to bare in mind if you don't have control of the document markup (e.g. webextension).
The location

function jump(hash) { location.replace("#" + hash) }

Using standard JSF API, add the client ID to PartialViewContext#getRenderIds()
.
FacesContext.getCurrentInstance().getPartialViewContext().getRenderIds().add("foo:bar");
Using PrimeFaces specific API, use PrimeFaces.Ajax#update()
.
PrimeFaces.current().ajax().update("foo:bar");
Or if you're not on PrimeFaces 6.2+ yet, use RequestContext#update()
.
RequestContext.getCurrentInstance().update("foo:bar");
If you happen to use JSF utility library OmniFaces, use Ajax#update()
.
Ajax.update("foo:bar");
Regardless of the way, note that those client IDs should represent absolute client IDs which are not prefixed with the NamingContainer
separator character like as you would do from the view side on.
This is actually a modified version of the selected answer in order to support Unicode characters but I don't have enough reputation to comment there.

However I'm surprised that the Affinity Propagation (AP) method has been here suggested just to find the number of cluster for the k-means method, where in general AP do a better job clustering the data. Please see the scientific paper supporting this method in Science here:
Frey, Brendan J., and Delbert Dueck. "Clustering by passing messages between data points." science 315.5814 (2007): 972-976.
So if you are not biased toward k-means I suggest to use AP directly, which will cluster the data without requiring knowing the number of clusters:
library(apcluster)
apclus = apcluster(negDistMat(r=2), data)
show(apclus)
If negative euclidean distances are not appropriate, then you can use another similarity measures provided in the same package. For example, for similarities based on Spearman correlations, this is what you need:
sim = corSimMat(data, method="spearman")
apclus = apcluster(s=sim)
Please note that those functions for similarities in the AP package are just provided for simplicity. In fact, apcluster() function in R will accept any matrix of correlations. The same before with corSimMat() can be done with this:
sim = cor(data, method="spearman")
or
sim = cor(t(data), method="spearman")
depending on what you want to cluster on your matrix (rows or cols).
You can pass any command-line argument without additional plugins using --env
since webpack 2:
webpack --config webpack.config.js --env.foo=bar
Using the variable in webpack.config.js:
module.exports = function(env) {
if (env.foo === 'bar') {
// do something
}
}

If anyone just wants to validate a bearer token in the authorize phase using the current security practices you can,
add this to your Startup/ConfigureServices
services.AddSingleton<IAuthorizationHandler, BearerAuthorizationHandler>();
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme).AddJwtBearer();
services.AddAuthorization(options => options.AddPolicy("Bearer",
policy => policy.AddRequirements(new BearerRequirement())
)
);
and this in your codebase,
public class BearerRequirement : IAuthorizationRequirement
{
public async Task<bool> IsTokenValid(SomeValidationContext context, string token)
{
// here you can check if the token received is valid
return true;
}
}
public class BearerAuthorizationHandler : AuthorizationHandler<BearerRequirement>
{
public BearerAuthorizationHandler(SomeValidationContext thatYouCanInject)
{
...
}
protected override async Task HandleRequirementAsync(AuthorizationHandlerContext context, BearerRequirement requirement)
{
var authFilterCtx = (Microsoft.AspNetCore.Mvc.Filters.AuthorizationFilterContext)context.Resource;
string authHeader = authFilterCtx.HttpContext.Request.Headers["Authorization"];
if (authHeader != null && authHeader.Contains("Bearer"))
{
var token = authHeader.Replace("Bearer ", string.Empty);
if (await requirement.IsTokenValid(thatYouCanInject, token))
{
context.Succeed(requirement);
}
}
}
}
If the code doesn't reach context.Succeed(...)
it will Fail anyway (401).
And then in your controllers you can use
[Authorize(Policy = "Bearer", AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme)]
Because you wanted to install specific package "I need to install only 1 package for my SF2 distribution (DoctrineFixtures)."
php composer.phar require package/package-name:package-version

In my case I have index.html which embeds 2 views i.e view1.html and view2.html. I developed these 2 views independent of index.html and then tried to embed using route. So I had all the script files defined in the 2 view html files which was causing this warning. The warning disappeared after removing the inclusion of angularJS script files from views.
In short, the script files angularJS, jQuery and angular-route.js should be included only in index.html and not in view html files.

The most "complex" is with global context (state) that both parent and children could access and modify. Its a great solution when components are very deep in the tree hierarchy and so its costly to send props in each level.
In this case I think its not worth it, and more simple approach will bring us the results we want, just using the powerful React.useState()
.
As said we will deal with changes and store the data of our child component fieldEditor
in our parent fieldForm
. To do that
we will send a reference to the function that will deal and apply the changes to the fieldForm
state, you could do that with:
function FieldForm({ fields }) {
const [fieldsValues, setFieldsValues] = React.useState({});
const handleChange = (event, fieldId) => {
let newFields = { ...fieldsValues };
newFields[fieldId] = event.target.value;
setFieldsValues(newFields);
};
return (
<div>
{fields.map(field => (
<FieldEditor
key={field}
id={field}
handleChange={handleChange}
value={fieldsValues[field]}
/>
))}
<div>{JSON.stringify(fieldsValues)}</div>
</div>
);
}
Note that React.useState({})
will return an array with position 0 being the value specified on call (Empty object in this case), and position 1 being the reference to the function
that modifies the value.
Now with the child component, FieldEditor
, you don't even need to create a function with a return statement, a lean constant with an arrow function
will do!
const FieldEditor = ({ id, value, handleChange }) => (
<div className="field-editor">
<input onChange={event => handleChange(event, id)} value={value} />
</div>
);
Aaaaand we are done, nothing more, with just these two slime functional components we have our end goal "access" our child FieldEditor
value and show it off in our parent.
You could check the accepted answer from 5 years ago and see how Hooks made React code leaner (By a lot!).
Hope my answer helps you learn and understand more about Hooks, and if you want to check a working example here it is.
Check for "projtemp" and then check if the previous one is a number entry (like 19,18..etc..) if that is so then get the row no of that proj temp ....
and if that is not so ..then re-check that the previous entry is projtemp or a number entry ...
gcc objectfiles -o program -Wl,-Bstatic -ls1 -ls2 -Wl,-Bdynamic -ld1 -ld2
you can also use: -static-libgcc -static-libstdc++
flags for gcc libraries
keep in mind that if libs1.so
and libs1.a
both exists, the linker will pick libs1.so
if it's before -Wl,-Bstatic
or after -Wl,-Bdynamic
. Don't forget to pass -L/libs1-library-location/
before calling -ls1
.
Always use static in .c
files unless you need to reference the object from a different .c
module.
Never use static in .h
files, because you will create a different object every time it is included.
Is basically duplication of the other answers - but I didn't get it completely. maybe someone will finally understand it with this example now.
[ngClass]="['svg-icon', 'recolor-' + recolor, size ? 'size-' + size : '']"
will result for e.g. in
class="svg-icon recolor-red size-m"
For an explicit timezone-independent solution, use the pytz library.
import datetime
import pytz
pytz.utc.localize(datetime.datetime(2012,4,1,0,0), is_dst=False).timestamp()
Output (float): 1333238400.0
Although $date
is a part of MongoDB Extended JSON and that's what you get as default with mongoexport
I don't think you can really use it as a part of the query.
If try exact search with $date
like below:
db.foo.find({dt: {"$date": "2012-01-01T15:00:00.000Z"}})
you'll get error:
error: { "$err" : "invalid operator: $date", "code" : 10068 }
Try this:
db.mycollection.find({
"dt" : {"$gte": new Date("2013-10-01T00:00:00.000Z")}
})
or (following comments by @user3805045):
db.mycollection.find({
"dt" : {"$gte": ISODate("2013-10-01T00:00:00.000Z")}
})
ISODate
may be also required to compare dates without time (noted by @MattMolnar).
According to Data Types in the mongo Shell both should be equivalent:
The mongo shell provides various methods to return the date, either as a string or as a Date object:
- Date() method which returns the current date as a string.
- new Date() constructor which returns a Date object using the ISODate() wrapper.
- ISODate() constructor which returns a Date object using the ISODate() wrapper.
and using ISODate
should still return a Date object.
{"$date": "ISO-8601 string"}
can be used when strict JSON representation is required. One possible example is Hadoop connector.
Explained by Red Hat:
Cache Pages:
A cache is the part of the memory which transparently stores data so that future requests for that data can be served faster. This memory is utilized by the kernel to cache disk data and improve i/o performance.
The Linux kernel is built in such a way that it will use as much RAM as it can to cache information from your local and remote filesystems and disks. As the time passes over various reads and writes are performed on the system, kernel tries to keep data stored in the memory for the various processes which are running on the system or the data that of relevant processes which would be used in the near future. The cache is not reclaimed at the time when process get stop/exit, however when the other processes requires more memory then the free available memory, kernel will run heuristics to reclaim the memory by storing the cache data and allocating that memory to new process.
When any kind of file/data is requested then the kernel will look for a copy of the part of the file the user is acting on, and, if no such copy exists, it will allocate one new page of cache memory and fill it with the appropriate contents read out from the disk.
The data that is stored within a cache might be values that have been computed earlier or duplicates of original values that are stored elsewhere in the disk. When some data is requested, the cache is first checked to see whether it contains that data. The data can be retrieved more quickly from the cache than from its source origin.
SysV shared memory segments are also accounted as a cache, though they do not represent any data on the disks. One can check the size of the shared memory segments using ipcs -m command and checking the bytes column.
Buffers:
Buffers are the disk block representation of the data that is stored under the page caches. Buffers contains the metadata of the files/data which resides under the page cache. Example: When there is a request of any data which is present in the page cache, first the kernel checks the data in the buffers which contain the metadata which points to the actual files/data contained in the page caches. Once from the metadata the actual block address of the file is known, it is picked up by the kernel for processing.
Simply \newpage
or \pagebreak
will work, e.g.
hello world
\newpage
```{r, echo=FALSE}
1+1
```
\pagebreak
```{r, echo=FALSE}
plot(1:10)
```
This solution assumes you are knitting PDF. For HTML, you can achieve a similar effect by adding a tag <P style="page-break-before: always">
. Note that you likely won't see a page break in your browser (HTMLs don't have pages per se), but the printing layout will have it.

Not sure if the syntax is correct but the forumla in A2 will work for you,
in 2019 I faced the same problem and I searched the internet and found the following which I am sharing with all.
In android studio letter R stands for the resources and this error occurs because of the build process not able to sync resources with your project. In other words, this error is caused when Android Studio can’t generate your R.java file correctly. This problem happens when you shift code to another system or while building the android project for the first time. So when you create a new activity or new class you will see an error message like “cannot resolve symbol r” with a red underline.
Below you can find the possible ways to fix cannot resolve symbol r in android studio.
Update Project Gradle To Latest Version Always use the latest version of Gradle to work android studio properly.
Sync Project With Gradle File Once you update the Gradle plugin you need to sync project with the Gradle file. Open android studio and click on Files > Sync Project with Gradle Files option.
Clean and Rebuild Project The most effective solution is the simplest: clean and rebuild your project. Select Build > Clean Project from the Android Studio toolbar, wait a few moments, and then build your project by selecting Build > Rebuild Project.
Invalidate Caches / Restart If you encounter this error after moving some files and directories around, then it’s possible that the R.layout error is being caused by a mismatch between Android Studio’s cache and your project’s current layout. If you suspect this may be the case, then select File > Invalidate Caches / Restart > Invalidate and Restart from Android Studio’s toolbar. Issues with the names of your resources can also prevent the R.java file from being created correctly, so check that you don't have multiple resources with the same name and that none of your file names contain invalid characters. Android Studio only supports lowercase a-z, 0-9, full stops and underscores, and a single invalid character can cause an R.layout error across your entire project, even if you don’t actually use this resource anywhere in your project!
My problem and its solution: In my case, I applied all the above but could not solve the problem. Thus I started a new project and pasted my code one by one and validated my code with running the app. Finally, at one point when I first deleted the code in colors.xml and copied and pasted code below in colors.xml file, I got the error.
<color name="bg_login">#26ae90</color>
<color name="bg_register">#2e3237</color>
<color name="bg_main">#428bca</color>
<color name="white">#ffffff</color>
<color name="input_login">#222222</color>
<color name="input_login_hint">#999999</color>
<color name="input_register">#888888</color>

<color name="btn_login">#26ae90</color>
<color name="btn_login_bg">#eceef1</color>
<color name="lbl_name">#333333</color>
<color name="btn_logut_bg">#ff6861</color>
when I undo my changes the error vanished again. Thus my code in colors.xml is not the code above and the code already in colors.xml i.e
<color name="colorPrimary">#008577</color>
<color name="colorPrimaryDark">#00574B</color>
<color name="colorAccent">#D81B60</color>
<color name="bg_login">#26ae90</color>
<color name="bg_register">#2e3237</color>
<color name="bg_main">#428bca</color>
<color name="white">#ffffff</color>
<color name="input_login">#222222</color>

I loved the FireFox Header Spy extension so much that i built a HTTP Spy extension for Chrome. I used to use the developer tools too for debugging headers, but now my life is so much better.
Here is a Chrome extension that allows you to view request-, response headers and cookies without any extra clicks right after the page is loaded.
It also handles redirects. It comes with an unobtrusive micro-mode that only shows a hand picked selection of response headers and a normal mode that shows all the information.

You should use window.history

if you want a list of how much productId in each keyword here it's the code
SELECT count(productId), keyword FROM `Table_name` GROUP BY keyword;
Just wrap the button label in an extra span and add class="align-middle"
to both (the icon and the label). This will center your icon with text vertical.
<button id="edit-listing-form-house_Continue"
class="btn btn-large btn-primary"
style=""
value=""
name="Continue"
type="submit">
<span class="align-middle">Continue</span>
<i class="icon-ok align-middle" style="font-size:40px;"></i>
You can try PHP protect which is a free PHP obfuscator to obfuscate your PHP code. EDIT: This service is not live anymore.
It is very nice, easy to use and also free.
As for what others have written here about not using obfuscation because it can be broken etc:
I have only one thing to answer them - don't lock your house door because anyone can pick your lock.
This is exactly the case, obfuscation is not meant to prevent 100% code theft. It only needs to make it a time-consuming task so it will be cheaper to pay the original coder. Hope this helps.
Use ldd (man ldd) to show shared library dependencies. Running this on libqxcb.so
.../platforms$ ldd libqxcb.so
shows that xcb depends on libQt5DBus.so.5 in addition to libQt5Core.so.5 and libQt5Gui.so.5 (and many other system libs). Add libQt5DBus.so.5 to your collection of shared libs and you should be ready to move on.
The MOST CORRECT answer to your question is...
#content > div:first-of-type { /* css */ }
This will apply the CSS to the first div that is a direct child of #content (which may or may not be the first child element of #content)
Another option:
#content > div:nth-of-type(1) { /* css */ }
I have found a great work-around for this. It really only works practically if you want to be able to select up to 4 or so options from your drop down list but here it is:
For each "item" create as many rows as drop-down items you'd like to be able to select. So if you want to be able to select up to 3 characteristics from a given drop down list for each person on your list, create a total of 3 rows for each person. Then merge A:1-A:3, B:1-B:3, C:1-C:3 etc until you reach the column that you'd like your drop-down list to be. Don't merge those cells, instead place the your Data Validation drop-down in each of those cells.
Hope this is clear!!
Using jQuery 1.9.1 I just found out that, although technically identical)*, this did not work in IE10 (but in Firefox):
// did not work in IE10
$(function() {
$(window).resize(CmsContent.adjustSize);
});
while this worked in both browsers:
// did work in IE10
$(function() {
$(window).bind('resize', function() {
CmsContent.adjustSize();
};
});
Edit:
)* Actually not technically identical, as noted and explained in the comments by WraithKenny and Henry Blyth.
Here is a little code that is useful.
var uiHelper = function () {
var htmls = {};
var getHTML = function (url) {
/// <summary>Returns HTML in a string format</summary>
/// <param name="url" type="string">The url to the file with the HTML</param>
if (!htmls[url])
{
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("GET", url, false);
xmlhttp.send();
htmls[url] = xmlhttp.responseText;
};
return htmls[url];
};
return {
getHTML: getHTML
};
}();
--Convert the HTML string into a DOM Element
String.prototype.toDomElement = function () {
var wrapper = document.createElement('div');
wrapper.innerHTML = this;
var df= document.createDocumentFragment();
return df.addChilds(wrapper.children);
};
--prototype helper
HTMLElement.prototype.addChilds = function (newChilds) {
/// <summary>Add an array of child elements</summary>
/// <param name="newChilds" type="Array">Array of HTMLElements to add to this HTMLElement</param>

return this;
};

Make sure you reference the WebDriver.Support.dll assembly to gain access to the OpenQA.Selenium.Support.UI.SelectElement dropdown helper class. See this thread for additional details.
Edit: In this screenshot, you can see that I can get the options just fine. Is IE opening up when you create a new InternetExplorerDriver?
No need to create a GD resource, as someone else suggested.
$input = 'http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com';
$output = 'google.com.jpg';
file_put_contents($output, file_get_contents($input));
Note: this solution only works if you're setup to allow fopen access to URLs. If the solution above doesn't work, you'll have to use cURL.
This will show the 10th line of myfile.txt:
get-content myfile.txt | select -first 1 -skip 9
both -first
and -skip
are optional parameters, and -context

may be useful in similar situations.

Fully working code sample how to share file from inner app folder. Tested on Android 7 and Android 5.

The ObservableCollection
and its derivatives raises its property changes internally. The code in your setter should only be triggered if you assign a new TrulyObservableCollection<MyType>
to the MyItemsSource
property. That is, it should only happen once, from the constructor.
From that point forward, you'll get property change notifications from the collection, not from the setter in your viewmodel.
If you are using .NET Framework 4.5, the solution is to use EmailAddressAttribute
which resides inside System.ComponentModel.DataAnnotations
.
Your code should look similar to this:
[Display(Name = "Email address")]
[Required(ErrorMessage = "The email address is required")]
[EmailAddress(ErrorMessage = "Invalid Email Address")]
public string Email { get; set; }
Using ToString("HH:mm")
certainly gives you what you want as a string.
If you want the current hour/minute as numbers, string manipulation isn't necessary; you can use the TimeOfDay
property:
TimeSpan timeOfDay = fechaHora.TimeOfDay;
int hour = timeOfDay.Hours;
int minute = timeOfDay.Minutes;
Pretty much what Matt Davis said, with the following additional points:
For me the main differentiator with BackgroundWorker
is the automatic marshalling of the completed event via the SynchronizationContext
. In a UI context this means the completed event fires on the UI thread, and so can be used to update UI. This is a major differentiator if you are using the BackgroundWorker
in a UI context.
Tasks executed via the ThreadPool
cannot be easily cancelled (this includes ThreadPool
. QueueUserWorkItem
and delegates execute asyncronously). So whilst it avoids the overhead of thread spinup, if you need cancellation either use a BackgroundWorker
or (more likely outside of the UI) spin up a thread and keep a reference to it so you can call Abort()
.
I got this since I had a comment in a file I was adding to my JS, really awkward reason to what was going on - though when clicking on the VM
file that's pre-rendered and catches the error, you'll find out what exactly the error was, in my case it was simply uncommenting some code I was using.
The MaterialModule
was deprecated in the beta3 version with the goal that developers should only import into their applications what they are going to use and thus improve the bundle size.
The developers have now 2 options:
MyMaterialModule
which imports/exports the components that your application requires and can be imported by other (feature) modules in your application.Take the following as example (extracted from material page)
First approach:
import {MdButtonModule, MdCheckboxModule} from '@angular/material';
@NgModule({
imports: [MdButtonModule, MdCheckboxModule],
exports: [MdButtonModule, MdCheckboxModule],
})
export class MyOwnCustomMaterialModule { }
Then you can import this module into any of yours.
Second approach:
import {MdButtonModule, MdCheckboxModule} from '@angular/material';
@NgModule({
...
imports: [MdButtonModule, MdCheckboxModule],
...
})
export class PizzaPartyAppModule { }
Now you can use the respective material components in all the components declared in PizzaPartyAppModule
It is worth mentioning the following:
BrowserAnimationsModule
into your main module if you want the
animations to work@angular/cdk
to their package.json
(material dependency)BrowserModule
, as stated by the docs: Whichever approach you use, be sure to import the Angular Material modules after Angular's BrowserModule, as the import order matters for NgModules.
Well that is Because of
you are only able to encrypt data in blocks of 128 bits or 16 bytes. That's why you are getting that IllegalBlockSizeException exception. and the one way is to encrypt that data Directly into the String.
look this. Try and u will be able to resolve this
public static String decrypt(String encryptedData) throws Exception {
Key key = generateKey();
Cipher c = Cipher.getInstance(ALGO);
c.init(Cipher.DECRYPT_MODE, key);
String decordedValue = new BASE64Decoder().decodeBuffer(encryptedData).toString().trim();
System.out.println("This is Data to be Decrypted" + decordedValue);
return decordedValue;
}
hope that will help.
Also you need to disable below line in configuration file: bind-address = 127.0.0.1

Then just call the function wherever you want:

I was running into this error while converting from nvarchar to float.
What I had to do was to use the LEFT

To make a dropdown list you need two properties:
In your case you only have a list of string which cannot be exploited to create a usable drop down list.
While for number 2. you could have the value and the text be the same you need a property to bind to. You could use a weakly typed version of the helper:
@model List<string>
@Html.DropDownList(
"Foo",
new SelectList(
Model.Select(x => new { Value = x, Text = x }),
"Value",
"Text"
)
)
where Foo
will be the name of the ddl and used by the default model binder. So the generated markup might look something like this:
<select name="Foo" id="Foo">
<option value="item 1">item 1</option>
<option value="item 2">item 2</option>
<option value="item 3">item 3</option>
...
</select>
This being said a far better view model for a drop down list is the following:
public class MyListModel
{
public string SelectedItemId { get; set; }
public IEnumerable<SelectListItem> Items { get; set; }
}
and then:
@model MyListModel
@Html.DropDownListFor(
x => x.SelectedItemId,
new SelectList(Model.Items, "Value", "Text")
)
and if you wanted to preselect some option in this list all you need to do is to set the SelectedItemId
property of this view model to the corresponding Value
of some element in the Items
collection.

You need to use the NVL function, e.g.
SUM(NVL(regular,0) + NVL(overtime,0))
Both works. Instead of ==
you can write eq
In my experience, don't use ffmpeg for splitting/join.
MP4Box, is faster and light than ffmpeg. Please tryit.
Eg if you want to split a 1400mb MP4 file into two parts a 700mb you can use the following cmdl:
MP4Box -splits 716800 input.mp4
eg for concatenating two files you can use:
MP4Box -cat file1.mp4 -cat file2.mp4 output.mp4
Or if you need split by time, use -splitx StartTime:EndTime
:
MP4Box -add input.mp4 -splitx 0:15 -new split.mp4
It's something you can put "(args)" after and expect it to work. A callable is usually a method or a class. Methods get called, classes get instantiated.
What worked for me most of the time is to verify whether the Activity is not finishing.

res.end() is used to quickly end the response without sending any data.
An example for this would be starting a process on a server
app.get(/start-service, (req, res) => {
// Some logic here
exec('./application'); // dummy code
res.end();
});
If you would like to send data in your response then you should use res.send() instead
app.get(/start-service, (req, res) => {
res.send('{"age":22}');
});

This may be overkill for what you're looking for, but there is an npm package called marky
that you can use to do this. It gives you a couple of extra features beyond just starting and stopping a timer.
You just need to install it via npm
and then import the dependency anywhere you'd like to use it.
Here is a link to the npm
package:
https://www.npmjs.com/package/marky
An example of use after installing via npm would be as follows:
import * as _M from 'marky';
@Component({
selector: 'app-test',
templateUrl: './test.component.html',
styleUrls: ['./test.component.scss']
})
export class TestComponent implements OnInit {
Marky = _M;
}
constructor() {}
ngOnInit() {}
startTimer(key: string) {
this.Marky.mark(key);
}
stopTimer(key: string) {
this.Marky.stop(key);
}
key
is simply a string which you are establishing to identify that particular measurement of time. You can have multiple measures which you can go back and reference your timer stats using the keys you create.
I always prefer to use mixins for small CSS classes like fade in / out incase you want to use them in more than one class.
@mixin fade-in {
opacity: 1;
animation-name: fadeInOpacity;
animation-iteration-count: 1;
animation-timing-function: ease-in;
animation-duration: 2s;
}
@keyframes fadeInOpacity {
0% {
opacity: 0;
}
100% {
opacity: 1;
}
}
and if you don't want to use mixins, you can create a normal class .fade-in.
You may run into such problem while dealing with scraped data stored as Pandas DataFrame.
This solution works like charm if the list of values is present as text.
def textToList(hashtags):
return hashtags.strip('[]').replace('\'', '').replace(' ', '').split(',')
hashtags = "[ 'A','B','C' , ' D']"
hashtags = textToList(hashtags)
Output: ['A', 'B', 'C', 'D']
No external library required.
I had a similar problem and solved it using ROW_NUMBER() in combination with the OVER keyword. The task was to retrospectively populate a new TicketNo (integer) field in a simple table based on the original CreatedDate, and grouped by ModuleId - so that ticket numbers started at 1 within each Module group and incremented by date. The table already had a TicketID primary key (a GUID).
Here's the SQL:
UPDATE Tickets SET TicketNo=T2.RowNo
FROM Tickets
INNER JOIN
(select TicketID, TicketNo,
ROW_NUMBER() OVER (PARTITION BY ModuleId ORDER BY DateCreated) AS RowNo from Tickets)
AS T2 ON T2.TicketID = Tickets.TicketID
Worked a treat!
Probably the author won't need my answer anymore. Still, for sake of completeness i feel other users might find it useful. The best and most simple solution is to use $(window).load()
inside the body of the returned function. (alternatively you can use document.ready
. It really depends if you need all the images or not).
Using $timeout
in my humble opinion is a very weak option and may fail in some cases.
Here is the complete code i'd use:
.directive('directiveExample', function(){
return {
restrict: 'A',
link: function($scope, $elem, attrs){
$(window).load(function() {
//...JS here...
});
}
}
});

These messages are rather misleading and understandably a source of confusion. Older Ubuntu versions used Libav which is a fork of the FFmpeg project. FFmpeg returned in Ubuntu 15.04 "Vivid Vervet".
The fork was basically a non-amicable result of conflicting personalities and development styles within the FFmpeg community. It is worth noting that the maintainer for Debian/Ubuntu switched from FFmpeg to Libav on his own accord due to being involved with the Libav fork.
ffmpeg
vs the fake oneFor a while both Libav and FFmpeg separately developed their own version of ffmpeg
.
Libav then renamed their bizarro ffmpeg
to avconv
to distance themselves from the FFmpeg project. During the transition period the "not developed anymore" message was displayed to tell users to start using avconv
instead of their counterfeit version of ffmpeg
. This confused users into thinking that FFmpeg (the project) is dead, which is not true. A bad choice of words, but I can't imagine Libav not expecting such a response by general users.
This message was removed upstream when the fake "ffmpeg
" was finally removed from the Libav source, but, depending on your version, it can still show up in Ubuntu because the Libav source Ubuntu uses is from the ffmpeg-to-avconv transition period.
In June 2012, the message was re-worded for the package libav - 4:0.8.3-0ubuntu0.12.04.1
. Unfortunately the new "deprecated" message has caused additional user confusion.
Starting with Ubuntu 15.04 "Vivid Vervet", FFmpeg's ffmpeg
is back in the repositories again.
To further complicate matters, Libav chose a name that was historically used by FFmpeg to refer to its libraries (libavcodec, libavformat, etc). For example the libav-user mailing list, for questions and discussions about using the FFmpeg libraries, is unrelated to the Libav project.
If you are using avconv
then you are using Libav. If you are using ffmpeg
you could be using FFmpeg or Libav. Refer to the first line in the console output to tell the difference: the copyright notice will either mention FFmpeg or Libav.
Secondly, the version numbering schemes differ. Each of the FFmpeg or Libav libraries contains a version.h
header which shows a version number. FFmpeg will end in three digits, such as 57.67.100, and Libav will end in one digit such as 57.67.0. You can also view the library version numbers by running ffmpeg
or avconv
and viewing the console output.
ffmpeg
The real ffmpeg
is in the repository, so you can install it with:
apt-get install ffmpeg
Your options are:
ffmpeg
,ffmpeg
,These methods are non-intrusive, reversible, and will not interfere with the system or any repository packages.
Another possible option is to upgrade to Ubuntu 15.04 "Vivid Vervet" or newer and just use ffmpeg
from the repository.
For an interesting blog article on the situation, as well as a discussion about the main technical differences between the projects, see The FFmpeg/Libav situation.
You just need to set the table cell padding to zero. Here's a jsfiddle (using Bootstrap 2.3.2) with your code slightly modified:

I had the same thing in both Chrome and Safari aka Webkit browsers. I'm suspecting it's not a bug, but the incorrect use of css which 'breaks' the background.
In the Question above, the body background property is set to:
background: black;
Which is fine, but not entirely correct. There's no image background, thus...
background-color: black;
In addition to using Request.Form
and Request.QueryString
and depending on your specific scenario, it may also be useful to check the Page
's IsPostBack
property.

// HTTP Post
}
else
{
// HTTP Get
}
Generally, the system displays an ANR if an application cannot respond to user input.
In any situation in which your app performs a potentially lengthy operation, you should not perform the work on the UI thread, but instead create a worker thread and do most of the work there. This keeps the UI thread (which drives the user interface event loop) running and prevents the system from concluding that your code has frozen.
Android applications normally run entirely on a single thread by default the "UI thread" or "main thread"). This means anything your application is doing in the UI thread that takes a long time to complete can trigger the ANR dialog because your application is not giving itself a chance to handle the input event or intent broadcasts.
Therefore, any method that runs in the UI thread should do as little work as possible on that thread. In particular, activities should do as little as possible to set up in key life-cycle methods such as onCreate() and onResume(). Potentially long running operations such as network or database operations, or computationally expensive calculations such as resizing bitmaps should be done in a worker thread (or in the case of databases operations, via an asynchronous request).
private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> {
// Do the long-running work in here
protected Long doInBackground(URL... urls) {
int count = urls.length;
long totalSize = 0;
for (int i = 0; i < count; i++) {
totalSize += Downloader.downloadFile(urls[i]);
publishProgress((int) ((i / (float) count) * 100));
// Escape early if cancel() is called
if (isCancelled()) break;
}
return totalSize;
}
// This is called each time you call publishProgress()
protected void onProgressUpdate(Integer... progress) {
setProgressPercent(progress[0]);
}
// This is called when doInBackground() is finished
protected void onPostExecute(Long result) {
showNotification("Downloaded " + result + " bytes");
}
}
To execute this worker thread, simply create an instance and call execute():
new DownloadFilesTask().execute(url1, url2, url3);

Extended - to provide more details based on some comments
The error
Error TS2306: File 'test.ts' is not a module.
Comes from the fact described here http://exploringjs.com/es6/ch_modules.html
17. Modules
This chapter explains how the built-in modules work in ECMAScript 6.
17.1 OverviewIn ECMAScript 6, modules are stored in files. There is exactly one module per file and one file per module. You have two ways of exporting things from a module. These two ways can be mixed, but it is usually better to use them separately.
17.1.1 Multiple named exports
There can be multiple named exports:
//------ lib.js ------ export const sqrt = Math.sqrt; export function square(x) { return x * x; } export function diag(x, y) { return sqrt(square(x) + square(y)); } ...
17.1.2 Single default export
There can be a single default export. For example, a function:
//------ myFunc.js ------ export default function () { ··· } // no semicolon!
Based on the above we need the export
, as a part of the test.js file. Let's adjust the content of it like this:
// test.js - exporting es6
export module App {
export class SomeClass {
getName(): string {
return 'name';
}
}
export class OtherClass {
getName(): string {
return 'name';
}
}
}
And now we can import it with these thre ways:
import * as app1 from "./test";
import app2 = require("./test");
import {App} from "./test";
And we can consume imported stuff like this:
var a1: app1.App.SomeClass = new app1.App.SomeClass();
var a2: app1.App.OtherClass = new app1.App.OtherClass();
var b1: app2.App.SomeClass = new app2.App.SomeClass();
var b2: app2.App.OtherClass = new app2.App.OtherClass();
var c1: App.SomeClass = new App.SomeClass();
var c2: App.OtherClass = new App.OtherClass();
and call the method to see it in action:
console.log(a1.getName())
console.log(a2.getName())
console.log(b1.getName())
console.log(b2.getName())
console.log(c1.getName())
console.log(c2.getName())
Original part is trying to help to reduce the amount of complexity in usage of the namespace
I would really strongly suggest to check this Q & A:
Let me cite the first sentence:
Do not use "namespaces" in external modules.
Don't do this.
Seriously. Stop.
...
In this case, we just do not need module
inside of test.ts
. This could be the content of it adjusted test.ts
:
export class SomeClass
{
getName(): string
{
return 'name';
}
}

In the previous example, when we consumed each validator, each module only exported one value. In cases like this, it's cumbersome to work with these symbols through their qualified name when a single identifier would do just as well.
The
export =
syntax specifies a single object that is exported from the module. This can be a class, interface, module, function, or enum. When imported, the exported symbol is consumed directly and is not qualified by any name.
we can later consume it like this:
import App = require('./test');
var sc: App.SomeClass = new App.SomeClass();
sc.getName();
Read more here:
In some cases, you may want to only load a module under some conditions. In TypeScript, we can use the pattern shown below to implement this and other advanced loading scenarios to directly invoke the module loaders without losing type safety.
The compiler detects whether each module is used in the emitted JavaScript. For modules that are only used as part of the type system, no require calls are emitted. This culling of unused references is a good performance optimization, and also allows for optional loading of those modules.
The core idea of the pattern is that the import id = require('...') statement gives us access to the types exposed by the external module. The module loader is invoked (through require) dynamically, as shown in the if blocks below. This leverages the reference-culling optimization so that the module is only loaded when needed. For this pattern to work, it's important that the symbol defined via import is only used in type positions (i.e. never in a position that would be emitted into the JavaScript).
Unfortunately none of the above solved the problem for me.
I didn't want to edit the bootstrap-responsive.css so I went the easy way:
@media (min-width: 768px) and (max-width: 979px)
(line 461 with latest bootstrap version 2.3.1 as of today)@media (min-width: 979px)
in the place where it said @media (min-width: 768px) and (max-width: 979px)
before. This sets the from 768 to 979 style to everything above 768.That's it. It's not optimal, you will have duplicated css, but it works 100% perfect!
You have to use the encoding as latin1 to read this file as there are some special character in this file, use the below code snippet to read the file.
The problem here is the encoding type. When Python can't convert the data to be read, it gives an error.
You can you latin1 or other encoding values.
I say try and test to find the right one for your dataset.
Extract jar file for ex. with winrar and use CAVAJ:
Cavaj Java Decompiler is a graphical freeware utility that reconstructs Java source code from CLASS files.
here is video tutorial if you need: https://www.youtube.com/watch?v=ByLUeem7680
Your code should be modified in this way:
httpClient.BaseAddress = new Uri("https://foobar.com/");
You have just to use the https:
URI scheme.
There's a useful page here on MSDN about the secure HTTP connections. Indeed:
Use the https: URI scheme
The HTTP Protocol defines two URI schemes:
http : Used for unencrypted connections.
https : Used for secure connections that should be encrypted. This option also uses digital certificates and certificate authorities to verify that the server is who it claims to be.
Moreover, consider that the HTTPS connections use a SSL certificate. Make sure your secure connection has this certificate otherwise the requests will fail.
EDIT:
Above code works fine for making http calls. But when I change the scheme to https it does not work, let me post the error.
What does it mean doesn't work? The requests fail? An exception is thrown? Clarify your question.
If the requests fail, then the issue should be the SSL certificate.
To fix the issue, you can use the class HttpWebRequest
and then its property ClientCertificate
.
Furthermore, you can find here a useful sample about how to make a HTTPS request using the certificate.
An example is the following (as shown in the MSDN page linked before):
//You must change the path to point to your .cer file location.
X509Certificate Cert = X509Certificate.CreateFromCertFile("C:\\mycert.cer");
// Handle any certificate errors on the certificate from the server.
ServicePointManager.CertificatePolicy = new CertPolicy();
// You must change the URL to point to your Web server.
HttpWebRequest Request = (HttpWebRequest)WebRequest.Create("https://YourServer/sample.asp");
Request.ClientCertificates.Add(Cert);
Request.UserAgent = "Client Cert Sample";
Request.Method = "GET";
HttpWebResponse Response = (HttpWebResponse)Request.GetResponse();
Do you mean like this?

and this text should be right justified?

<!-- ... --->
If yes

For Python 2 I have found that the boto3 library does not source the region from the ~/.aws/config
if the region is defined in a different profile to default.
So you have to define it in the session creation.
session = boto3.Session(
profile_name='NotDefault',
region_name='ap-southeast-2'
)
print(session.available_profiles)
client = session.client(
'ec2'
)
Where my ~/.aws/config
file looks like this:
[default]
region=ap-southeast-2
[NotDefault]
region=ap-southeast-2
I do this because I use different profiles for different logins to AWS, Personal and Work.
Python tries hard to use the most precise time function for your platform to implement time.time()
:
/* Implement floattime() for various platforms */
static double
floattime(void)
{
/* There are three ways to get the time:
(1) gettimeofday() -- resolution in microseconds
(2) ftime() -- resolution in milliseconds
(3) time() -- resolution in seconds
In all cases the return value is a float in seconds.
Since on some systems (e.g. SCO ODT 3.0) gettimeofday() may
fail, so we fall back on ftime() or time().
Note: clock resolution does not imply clock accuracy! */

Please put this code in head section
<link href='http://fonts.googleapis.com/css?family=Lato:400,700' rel='stylesheet' type='text/css'>
and use font-family: 'Lato', sans-serif;
in your css. For example:
h1 {
font-family: 'Lato', sans-serif;
font-weight: 400;
}
Or you can use manually also
Generate .ttf
font from fontSquiral
and can try this option
@font-face {
font-family: "Lato";
src: url('698242188-Lato-Bla.eot');
src: url('698242188-Lato-Bla.eot?#iefix') format('embedded-opentype'),

url('698242188-Lato-Bla.woff') format('woff'),
url('698242188-Lato-Bla.ttf') format('truetype');
font-weight: normal;
font-style: normal;
}
Called like this
body {
font-family: 'Lato', sans-serif;
}
Just get the class attribute:
var div1Class = $('#div1').attr('class');
Example
<div id="div1" class="accordion accordion_active">
To check the above div for classes contained in it
var a = ("#div1").attr('class');
console.log(a);
console output
accordion accordion_active
You can execute commands in parallel with start
like this:
start "" ping myserver
start "" nslookup myserver
start "" morecommands
They will each start in their own command prompt and allow you to run multiple commands at the same time from one batch file.
Hope this helps!

}x; #x switch allows whitespace in regex to allow documentation.
#values trapped in $1 $2 $3, so do whatever you need to:
#Perl lets you use any characters as delimiters, i like pipes because
#they reduce the amount of escaping when using file paths
m|$regex| && print "$1 : $2 : $3";
#alternatively if(m|$regex|) {doOne($1); doTwo($2) ... }
Though if it were anything other than formatting, I would implement a main loop to handle files and flesh out the body of the script rather than rely ing on the commandline switches for the looping.
This is my solution

With this version of python 3:
/opt/anaconda3/bin/python --version

Looking at the details of the error, I found the lines of codes causing the failure:
/opt/anaconda3/lib/python3.6/site-packages/sklearn/utils/validation.py in _assert_all_finite(X)
56 and not np.isfinite(X).all()):
57 raise ValueError("Input contains NaN, infinity"
---> 58 " or a value too large for %r." % X.dtype)
59
60
ValueError: Input contains NaN, infinity or a value too large for dtype('float64').
From this, I was able to extract the correct way to test what was going on with my data using the same test which fails given by the error message: np.isfinite(X)
Then with a quick and dirty loop, I was able to find that my data indeed contains nans
:
print(p[:,0].shape)
index = 0
for i in p[:,0]:
if not np.isfinite(i):
print(index, i)
index +=1

Now all I have to do is remove the values at these indexes.
$(this)
instead of $this
$("tr.item").each(function() {
var quantity1 = $(this).find("input.name").val(),
quantity2 = $(this).find("input.id").val();
});
Example 1 is for asp.net applications using forms authenication. This is common practice for internet applications because user is unauthenticated until it is authentcation against some security module.
Example 2 is for asp.net application using windows authenication. Windows Authentication uses Active Directory to authenticate users. The will prevent access to your application. I use this feature on intranet applications.

I can handle the title, full message, but the icon is always a default white circle:
Instead of my custom icon in the code (setSmallIcon or setSmallIcon) or default icon from the app:
Intent intent = new Intent(this, MainActivity.class);
// use System.currentTimeMillis() to have a unique ID for the pending intent
PendingIntent pIntent = PendingIntent.getActivity(this, (int) System.currentTimeMillis(), intent, 0);

In react or react native the way component hide/show or add/remove does not work like in android or iOS. Most of us think there would be the similar strategy like
View.hide = true or parentView.addSubView(childView)
But the way react native work is completely different. The only way to achieve this kind of functionality is to include your component in your DOM or remove from DOM.
Here in this example I am going set the visibility of text view based on the button click.
The idea behind this task is the create a state variable called state having the initial value set to false when the button click event happens then it value toggles. Now we will use this state variable during the creation of component.
import renderIf from './renderIf'
class FetchSample extends Component {
constructor(){
super();
this.state ={
status:false
}
}
toggleStatus(){
this.setState({
status:!this.state.status
});
console.log('toggle button handler: '+ this.state.status);
}
render() {
return (
<View style={styles.container}>
{renderIf(this.state.status)(
<Text style={styles.welcome}>
I am dynamic text View
</Text>
)}
<TouchableHighlight onPress={()=>this.toggleStatus()}>
<Text>
touchme
</Text>
</TouchableHighlight>
</View>
);
}
}
the only one thing to notice in this snippet is renderIf
which is actually a function which will return the component passed to it based on the boolean value passed to it.
renderIf(predicate)(element)
renderif.js
'use strict';
const isFunction = input => typeof input === 'function';
export default predicate => elemOrThunk =>
predicate ? (isFunction(elemOrThunk) ? elemOrThunk() : elemOrThunk) : null;
First you can get the rowid
of the selected row with respect of getGridParam
method and 'selrow' as the parameter and then you can use getCell to get the cell value from the corresponding column:
var myGrid = $('#list'),
selRowId = myGrid.jqGrid ('getGridParam', 'selrow'),
celValue = myGrid.jqGrid ('getCell', selRowId, 'columnName');
The 'columnName'
should be the same name which you use in the 'name'
property of the colModel
. If you need values from many column of the selected row you can use getRowData instead of getCell.
children
const Wrapper = ({children}) => (
<div>
<div>header</div>
<div>{children}</div>
<div>footer</div>
</div>
);
const App = ({name}) => <div>Hello {name}</div>;
const WrappedApp = ({name}) => (
<Wrapper>
<App name={name}/>
</Wrapper>
);
render(<WrappedApp name="toto"/>,node);
This is also known as transclusion
in Angular.
children
is a special prop in React and will contain what is inside your component's tags (here <App name={name}/>
is inside Wrapper
, so it is the children
Note that you don't necessarily need to use children
, which is unique for a component, and you can use normal props too if you want, or mix props and children:
const AppLayout = ({header,footer,children}) => (
<div className="app">
<div className="header">{header}</div>
<div className="body">{children}</div>
<div className="footer">{footer}</div>
</div>
);
const appElement = (
<AppLayout
header={<div>header</div>}
footer={<div>footer</div>}
>
<div>body</div>
</AppLayout>
);
render(appElement,node);
This is simple and fine for many usecases, and I'd recommend this for most consumer apps.
It is possible to pass render functions to a component, this pattern is generally called render prop
, and the children
prop is often used to provide that callback.
This pattern is not really meant for layout. The wrapper component is generally used to hold and manage some state and inject it in its render functions.
Counter example:
const Counter = () => (
<State initial={0}>
{(val, set) => (
<div onClick={() => set(val + 1)}>
clicked {val} times
</div>
)}
</State>
);
You can get even more fancy and even provide an object
<Promise promise={somePromise}>
{{
loading: () => <div>...</div>,
success: (data) => <div>{data.something}</div>,
error: (e) => <div>{e.message}</div>,
}}
</Promise>
Note you don't necessarily need to use children
, it is a matter of taste/API.
<Promise
promise={somePromise}
renderLoading={() => <div>...</div>}
renderSuccess={(data) => <div>{data.something}</div>}
renderError={(e) => <div>{e.message}</div>}
/>
As of today, many libraries are using render props (React context, React-motion, Apollo...) because people tend to find this API more easy than HOC's. react-powerplug is a collection of simple render-prop components. react-adopt helps you do composition.
const wrapHOC = (WrappedComponent) => {
class Wrapper extends React.PureComponent {
render() {
return (
<div>
<div>header</div>
<div><WrappedComponent {...this.props}/></div>
<div>footer</div>
</div>
);
}
}
return Wrapper;
}
const App = ({name}) => <div>Hello {name}</div>;
const WrappedApp = wrapHOC(App);
render(<WrappedApp name="toto"/>,node);
An Higher-Order Component / HOC is generally a function that takes a component and returns a new component.
Using an Higher-Order Component can be more performant than using children
or render props
, because the wrapper can have the ability to short-circuit the rendering one step ahead with shouldComponentUpdate
.
Here we are using PureComponent
. When re-rendering the app, if the WrappedApp
name prop does not change over time, the wrapper has the ability to say "I don't need to render because props (actually, the name) are the same as before". With the children
based solution above, even if the wrapper is PureComponent
, it is not the case because the children element is recreated everytime the parent renders, which means the wrapper will likely always re-render, even if the wrapped component is pure. There is a babel plugin that can help mitigate this and ensure a constant children
element over time.
Higher-Order Components can give you better performance. It's not so complicated but it certainly looks unfriendly at first.
Don't migrate your whole codebase to HOC after reading this. Just remember that on critical paths of your app you might want to use HOCs instead of runtime wrappers for performance reasons, particularly if the same wrapper is used a lot of times it's worth considering making it an HOC.
Redux used at first a runtime wrapper <Connect>
and switched later to an HOC connect(options)(Comp)
for performance reasons (by default, the wrapper is pure and use shouldComponentUpdate
). This is the perfect illustration of what I wanted to highlight in this answer.
Note if a component has a render-prop API, it is generally easy to create a HOC on top of it, so if you are a lib author, you should write a render prop API first, and eventually offer an HOC version. This is what Apollo does with <Query>
render-prop component, and the graphql
HOC using it.
Personally, I use both, but when in doubt I prefer HOCs because:
compose(hoc1,hoc2)(Comp)
) compared to render propsI don't hesitate to use/create HOC versions of my favorite tools:
Context.Consumer
compSubscribe
graphql
HOC of Apollo instead of Query
render propIn my opinion, sometimes render props make the code more readable, sometimes less... I try to use the most pragmatic solution according to the constraints I have. Sometimes readability is more important than performances, sometimes not. Choose wisely and don't bindly follow the 2018 trend of converting everything to render-props.
The accepted answer from @arshajii is totally correct. However just being more explicit by saying below,
StringUtils.isBlank()
StringUtils.isBlank(null) = true
StringUtils.isBlank("") = true
StringUtils.isBlank(" ") = true
StringUtils.isBlank("bob") = false
StringUtils.isBlank(" bob ") = false
StringUtils.isEmpty
StringUtils.isEmpty(null) = true
StringUtils.isEmpty("") = true
StringUtils.isEmpty(" ") = false
StringUtils.isEmpty("bob") = false
StringUtils.isEmpty(" bob ") = false
I am assuming: If you sent the JSON value through browser then any number you sent that will be the type float64 so you cant get the value directly int in golang.
So do the conversion like:
//As that says:
fmt.Fprintf(w, "Type = %v", val) // <--- Type = float64
var iAreaId int = int(val.(float64))
This way you can get exact value what you wanted.
A technique I use is something like the following. Define a global variable that you can use for one or multiple try catch blocks depending on what you're trying to debug and use the following structure:
if(!GlobalTestingBool)
{
try
{
SomeErrorProneMethod();
}
catch (...)
{
// ... Error handling ...
}
}
else
{
SomeErrorProneMethod();
}
I find this gives me a bit more flexibility in terms of testing because there are still some exceptions I don't want the IDE to break on.
It's just a 'safety' warning. It is a relatively common idiom, but also a relatively common error when you meant to have ==
in there. You can make the warning go away by adding another set of parentheses:
while ((list = list->next))
To check whether the input file is empty or not
by using the file length property, index
should be specified like the following:
var vidFileLength = $("#videoUploadFile")[0].files.length;
if(vidFileLength === 0){
alert("No file selected.");
}
Only ASCII or are other characters allowed too?
^\w*$
restricts (in Java) to ASCII letters/digits und underscore,
^[\pL\pN\p{Pc}]*$
also allows international characters/digits and "connecting punctuation".
Use the PHP function
void set_time_limit ( int $seconds )
The maximum execution time, in seconds. If set to zero, no time limit is imposed.
This function has no effect when PHP is running in safe mode. There is no workaround other than turning off safe mode or changing the time limit in the php.ini.
You can create a backup device in server object, let us say
BDTEST
and then create a batch file contain following command
sqlcmd -S 192.168.1.25 -E -Q "BACKUP DATABASE dbtest TO BDTEST"
let us say with name
backup.bat
then you can call
backup.bat
in task scheduler according to your convenience
You have to style the image like this
#container img{width:100%;}
and the container with hidden overflow:
#container{width:250px; height:250px; overflow:hidden; border:1px solid #000;}
nil is an object pointer to nothing. Although semantically distinct from NULL, they are technically equivalent to one another.
On the framework level, Foundation defines NSNull, which defines a class method, +null, which returns the singleton NSNull object. NSNull is different from nil or NULL, in that it is an actual object, rather than a zero value.
Additionally, in Foundation/NSObjCRuntime.h, Nil is defined as a class pointer to nothing.
To assign a variable inside block which outside of block always use __block specifier before that variable your code should be like this:-
__block Person *aPerson = nil;
Many people will suggest you use MERGE
, but I caution you against it. By default, it doesn't protect you from concurrency and race conditions any more than multiple statements, but it does introduce other dangers:
http://www.mssqltips.com/sqlservertip/3074/use-caution-with-sql-servers-merge-statement/
Even with this "simpler" syntax available, I still prefer this approach (error handling omitted for brevity):
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
UPDATE dbo.table SET ... WHERE PK = @PK;
IF @@ROWCOUNT = 0
BEGIN
INSERT dbo.table(PK, ...) SELECT @PK, ...;
END
COMMIT TRANSACTION;
A lot of folks will suggest this way:
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
IF EXISTS (SELECT 1 FROM dbo.table WHERE PK = @PK)
BEGIN
UPDATE ...
END
ELSE
BEGIN
INSERT ...
END
COMMIT TRANSACTION;
But all this accomplishes is ensuring you may need to read the table twice to locate the row(s) to be updated. In the first sample, you will only ever need to locate the row(s) once. (In both cases, if no rows are found from the initial read, an insert occurs.)
Others will suggest this way:
BEGIN TRY
INSERT ...
END TRY
BEGIN CATCH
IF ERROR_NUMBER() = 2627
UPDATE ...
END CATCH
However, this is problematic if for no other reason than letting SQL Server catch exceptions that you could have prevented in the first place is much more expensive, except in the rare scenario where almost every insert fails. I prove as much here:
Not sure what you think you gain by having a single statement; I don't think you gain anything. MERGE
is a single statement but it still has to really perform multiple operations anyway - even though it makes you think it doesn't.
In Python 2.6+, you could use io.open()
that is default (builtin open()
) on Python 3:
import io
with io.open(filename, 'w', encoding=character_encoding) as file:
file.write(unicode_text)
It might be more convenient if you need to write the text incrementally (you don't need to call unicode_text.encode(character_encoding)
multiple times). Unlike codecs
module, io
module has a proper universal newlines support.
https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date/getYear
getYear
is no longer used and has been replaced by thegetFullYear
method.The
getYear
method returns the year minus 1900; thus:
- For years greater than or equal to 2000, the value returned by
getYear
is 100 or greater. For example, if the year is 2026,getYear
returns 126.- For years between and including 1900 and 1999, the value returned by
getYear
is between 0 and 99. For example, if the year is 1976,getYear
returns 76.- For years less than 1900, the value returned by
getYear
is less than 0. For example, if the year is 1800,getYear
returns -100.- To take into account years before and after 2000, you should use
getFullYear
instead ofgetYear
so that the year is specified in full.
echo "{$test}y";
You can use braces to remove ambiguity when interpolating variables directly in strings.
Also, this doesn't work with single quotes. So:
echo '{$test}y';
will output
{$test}y
Try it:
String command = "killall <your_proccess>";
Process p = Runtime.getRuntime().exec(command);
p.destroy();
if the process is still alive, add:
p.destroyForcibly();
At least for pip 1.3.1, it honors the http_proxy and https_proxy environment variables. Make sure you define both, as it will access the PYPI index using https.
export https_proxy="http://<proxy.server>:<port>"
pip install TwitterApi
hash_map is a non-standard extension. unordered_map is part of std::tr1, and will be moved into the std namespace for C++0x. http://en.wikipedia.org/wiki/Unordered_map_%28C%2B%2B%29
double degree = fmodf((atan2(x, y) * (180.0 / M_PI)) + 360, 360);
This will return degree from 0°-360° counter-clockwise, 0° is at 3 o'clock.
Take a look at your code :
getUsers(): Observable<User[]> {
return Observable.create(observer => {
this.http.get('http://users.org').map(response => response.json();
})
}
and code from https://angular.io/docs/ts/latest/tutorial/toh-pt6.html (BTW. really good tutorial, you should check it out)
getHeroes(): Promise<Hero[]> {
return this.http.get(this.heroesUrl)
.toPromise()
.then(response => response.json().data as Hero[])
.catch(this.handleError);
}
The HttpService inside Angular2 already returns an observable, sou don't need to wrap another Observable around like you did here:
return Observable.create(observer => {
this.http.get('http://users.org').map(response => response.json()
Try to follow the guide in link that I provided. You should be just fine when you study it carefully.
---EDIT----
First of all WHERE you log the this.users variable? JavaScript isn't working that way. Your variable is undefined and it's fine, becuase of the code execution order!
Try to do it like this:
getUsers(): void {
this.userService.getUsers()
.then(users => {
this.users = users
console.log('this.users=' + this.users);
});
}
See where the console.log(...) is!
Try to resign from toPromise() it's seems to be just for ppl with no RxJs background.
Catch another link: https://scotch.io/tutorials/angular-2-http-requests-with-observables Build your service once again with RxJs observables.
simply run
php artisan key:generate
its worked for me
That's what we have in our applications:
Attribute
public class HttpParamActionAttribute : ActionNameSelectorAttribute
{
public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
{
if (actionName.Equals(methodInfo.Name, StringComparison.InvariantCultureIgnoreCase))
return true;
var request = controllerContext.RequestContext.HttpContext.Request;
return request[methodInfo.Name] != null;
}
}
Actions decorated with it:
[HttpParamAction]
public ActionResult Save(MyModel model)
{
// ...
}
[HttpParamAction]
public ActionResult Publish(MyModel model)
{
// ...
}
HTML/Razor
@using (@Html.BeginForm())
{
<!-- form content here -->
<input type="submit" name="Save" value="Save" />
<input type="submit" name="Publish" value="Publish" />
}
name
attribute of submit button should match action/method name
This way you do not have to hard-code urls in javascript
If you are using Linux and you got the permission error, you will need to raise the allowed limit in the /etc/limits.conf
or /etc/security/limits.conf
file (where the file is located depends on your specific Linux distribution).
For example to allow anyone on the machine to raise their number of open files up to 10000 add the line to the limits.conf
file.
* hard nofile 10000
Then logout and relogin to your system and you should be able to do:
ulimit -n 10000
without a permission error.
The accepted answer is great. I am making a table that helps in quick comprehension of the topic. The explanation involves a simple variable a
as well as an indexed array arr
.
If we set
a=apple # a simple variable
arr=(apple) # an indexed array with a single element
and then echo
the expression in the second column, we would get the result / behavior shown in the third column. The fourth column explains the behavior.
# | Expression | Result | Comments |
---|---|---|---|
1 | "$a" |
apple |
variables are expanded inside "" |
2 | '$a' |
$a |
variables are not expanded inside '' |
3 | "'$a'" |
'apple' |
'' has no special meaning inside "" |
4 | '"$a"' |
"$a" |
"" is treated literally inside '' |
5 | '\'' |
invalid | can not escape a ' within '' ; use "'" or $'\'' (ANSI-C quoting) |
6 | "red$arocks" |
red |
$arocks does not expand $a ; use ${a}rocks to preserve $a |
7 | "redapple$" |
redapple$ |
$ followed by no variable name evaluates to $ |
8 | '\"' |
\" |
\ has no special meaning inside '' |
9 | "\'" |
\' |
\' is interpreted inside "" but has no significance for ' |
10 | "\"" |
" |
\" is interpreted inside "" |
11 | "*" |
* |
glob does not work inside "" or '' |
12 | "\t\n" |
\t\n |
\t and \n have no special meaning inside "" or '' ; use ANSI-C quoting |
13 | "`echo hi`" |
hi |
`` and $() are evaluated inside "" (backquotes are retained in actual output) |
14 | '`echo hi`' |
echo hi | `` and $() are not evaluated inside '' (backquotes are retained in actual output) |
15 | '${arr[0]}' |
${arr[0]} |
array access not possible inside '' |
16 | "${arr[0]}" |
apple |
array access works inside "" |
17 | $'$a\'' |
$a' |
single quotes can be escaped inside ANSI-C quoting |
18 | "$'\t'" |
$'\t' |
ANSI-C quoting is not interpreted inside "" |
19 | '!cmd' |
!cmd |
history expansion character '!' is ignored inside '' |
20 | "!cmd" |
cmd args |
expands to the most recent command matching "cmd" |
21 | $'!cmd' |
!cmd |
history expansion character '!' is ignored inside ANSI-C quotes |

I resolved it like this:
<% @user.errors.each do |attr, msg| %>
<li>
<%= @user.errors.full_messages_for(attr).first if @user.errors[attr].first == msg %>
</li>
<% end %>
This way you are using the locales for the error messages.
Have you tried to use Sleep?
There's an example HERE (copied below):
Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Private Sub Form_Activate()
frmSplash.Show
DoEvents
Sleep 1000
Unload Me
frmProfiles.Show
End Sub
Notice it might freeze the application for the chosen amount of time.
str_replace
with arrays just performs all the replacements sequentially. Use strtr
instead to do them all at once:
$new_message = strtr($message, 'lmnopq...', 'abcdef...');
c is the new dictionary, and a is your original dictionary, {'z','w'} are the keys you want to remove from a
c = {key:a[key] for key in a.keys() - {'z', 'w'}}

Complete working example in Kotlin, I have replaced my API keys with 1111...
val apiService = API.getInstance().retrofit.create(MyApiEndpointInterface::class.java)
val params = HashMap<String, String>()
params["q"] = "munich,de"
params["APPID"] = "11111111111111111"
val call = apiService.getWeather(params)
call.enqueue(object : Callback<WeatherResponse> {
override fun onFailure(call: Call<WeatherResponse>?, t: Throwable?) {
Log.e("Error:::","Error "+t!!.message)
}
override fun onResponse(call: Call<WeatherResponse>?, response: Response<WeatherResponse>?) {
if (response != null && response.isSuccessful && response.body() != null) {
Log.e("SUCCESS:::","Response "+ response.body()!!.main.temp)
temperature.setText(""+ response.body()!!.main.temp)
}
}
})
This is the best way, I know of to create dynamic variables in python.
my_dict = {}

my_dict[x] = 4
I found a similar, but not the same question here Creating dynamically named variables from user input
Yes you can! For a simple repository that only publish/retrieve artifacts, you can use nginx.
Make sure nginx has http dav module enabled, it should, but nonetheless verify it.
Configure nginx http dav module:
In Windows: d:\servers\nginx\nginx.conf
location / {
# maven repository
dav_methods PUT DELETE MKCOL COPY MOVE;
create_full_put_path on;
dav_access user:rw group:rw all:r;
}
In Linux (Ubuntu): /etc/nginx/sites-available/default
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
# try_files $uri $uri/ =404; # IMPORTANT comment this
dav_methods PUT DELETE MKCOL COPY MOVE;
create_full_put_path on;
dav_access user:rw group:rw all:r;
}
Don't forget to give permissions to the directory where the repo will be located:
sudo chmod +777 /var/www/html/repository
In your project's pom.xml
add the respective configuration:
Retrieve artifacts:
<repositories>
<repository>
<id>repository</id>
<url>http://<your.ip.or.hostname>/repository</url>
</repository>
</repositories>
Publish artifacts:
<build>

To publish artifacts use mvn deploy
. To retrieve artifacts, maven will do it automatically.
And there you have it a simple maven repo.
In Android you can create shared buffer between C++ and Java (with directAlloc method) and manipulate it in both sides.
Here's an example script which demonstrates certificate validation:
import httplib
import re
import socket
import sys
import urllib2
import ssl
class InvalidCertificateException(httplib.HTTPException, urllib2.URLError):
def __init__(self, host, cert, reason):
httplib.HTTPException.__init__(self)
self.host = host
self.cert = cert
self.reason = reason
def __str__(self):
return ('Host %s returned an invalid certificate (%s) %s\n' %
(self.host, self.reason, self.cert))
class CertValidatingHTTPSConnection(httplib.HTTPConnection):
default_port = httplib.HTTPS_PORT
def __init__(self, host, port=None, key_file=None, cert_file=None,
ca_certs=None, strict=None, **kwargs):
httplib.HTTPConnection.__init__(self, host, port, strict, **kwargs)
self.key_file = key_file
self.cert_file = cert_file
self.ca_certs = ca_certs
if self.ca_certs:
self.cert_reqs = ssl.CERT_REQUIRED
else:
self.cert_reqs = ssl.CERT_NONE
def _GetValidHostsForCert(self, cert):
if 'subjectAltName' in cert:
return [x[1] for x in cert['subjectAltName']
if x[0].lower() == 'dns']
else:
return [x[0][1] for x in cert['subject']
if x[0][0].lower() == 'commonname']
def _ValidateCertificateHostname(self, cert, hostname):
hosts = self._GetValidHostsForCert(cert)
for host in hosts:
host_re = host.replace('.', '\.').replace('*', '[^.]*')
if re.search('^%s$' % (host_re,), hostname, re.I):
return True
return False
def connect(self):
sock = socket.create_connection((self.host, self.port))
self.sock = ssl.wrap_socket(sock, keyfile=self.key_file,
certfile=self.cert_file,
cert_reqs=self.cert_reqs,
ca_certs=self.ca_certs)
if self.cert_reqs & ssl.CERT_REQUIRED:
cert = self.sock.getpeercert()
hostname = self.host.split(':', 0)[0]
if not self._ValidateCertificateHostname(cert, hostname):
raise InvalidCertificateException(hostname, cert,
'hostname mismatch')

Here is a newer way of how to turn a Console Application to a Windows Service as a Worker Service based on the latest .Net Core 3.1.
If you create a Worker Service from Visual Studio 2019 it will give you almost everything you need for creating a Windows Service out of the box, which is also what you need to change to the console application in order to convert it to a Windows Service.
Here are the changes you need to do:
Install the following NuGet packages
Install-Package Microsoft.Extensions.Hosting.WindowsServices -Version 3.1.0
Install-Package Microsoft.Extensions.Configuration.Abstractions -Version 3.1.0
Change Program.cs to have an implementation like below:
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
namespace ConsoleApp
{
class Program
{
public static void Main(string[] args)
{
CreateHostBuilder(args).UseWindowsService().Build().Run();
}
private static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureServices((hostContext, services) =>
{
services.AddHostedService<Worker>();
});
}
}
and add Worker.cs where you will put the code which will be run by the service operations:
using Microsoft.Extensions.Hosting;
using System.Threading;
using System.Threading.Tasks;
namespace ConsoleApp
{
public class Worker : BackgroundService
{
protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
//do some operation
}
public override Task StartAsync(CancellationToken cancellationToken)
{
return base.StartAsync(cancellationToken);
}
public override Task StopAsync(CancellationToken cancellationToken)
{
return base.StopAsync(cancellationToken);
}
}
}
When everything is ready, and the application has built successfully, you can use sc.exe to install your console application exe as a Windows Service with the following command:
sc.exe create DemoService binpath= "path/to/your/file.exe"
I know this is a late answer, but I found this question because I had the same problem. I think I found the answer in this post on lexandera.com. The code below is basically a cut-and-paste from the site. It seems to do the trick.
final Context myApp = this;
/* An instance of this class will be registered as a JavaScript interface */
class MyJavaScriptInterface
{
@JavascriptInterface
@SuppressWarnings("unused")
public void processHTML(String html)
{
// process the html as needed by the app
}
}
final WebView browser = (WebView)findViewById(R.id.browser);
/* JavaScript must be enabled if you want it to work, obviously */
browser.getSettings().setJavaScriptEnabled(true);
/* Register a new JavaScript interface called HTMLOUT */
browser.addJavascriptInterface(new MyJavaScriptInterface(), "HTMLOUT");
/* WebViewClient must be set BEFORE calling loadUrl! */
browser.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url)
{
/* This call inject JavaScript into the page which just finished loading. */
browser.loadUrl("javascript:window.HTMLOUT.processHTML('<head>'+document.getElementsByTagName('html')[0].innerHTML+'</head>');");
}
});
/* load a web page */
browser.loadUrl("http://lexandera.com/files/jsexamples/gethtml.html");
Don't forget to take into consideration the global flag in your regexp :
var reg = /abc/g;
!!'abcdefghi'.match(reg); // => true
!!'abcdefghi'.match(reg); // => true
reg.test('abcdefghi'); // => true
reg.test('abcdefghi'); // => false <=
This is because Regexp keeps track of the lastIndex when a new match is found.
Temp tables are always on disk - so as long as your CTE can be held in memory, it would most likely be faster (like a table variable, too).
But then again, if the data load of your CTE (or temp table variable) gets too big, it'll be stored on disk, too, so there's no big benefit.
In general, I prefer a CTE over a temp table since it's gone after I used it. I don't need to think about dropping it explicitly or anything.
So, no clear answer in the end, but personally, I would prefer CTE over temp tables.
Right-click an object in Chrome's console and select Store as Global Variable
from the context menu. It will return something like temp1
as the variable name.
Chrome also has a copy()
method, so copy(temp1)
in the console should copy that object to your clipboard.
Note on Recursive Objects: If you're trying to copy a recursive object, you will get [object Object]
. The way out is to copy(JSON.stringify(temp1))
, the object will be fully copied to your clipboard as a valid JSON, so you'd be able to format it as you wish, using one of many resources.
If you are using express.json()
and bodyParser together it will give error as express sets its own limit.
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
remove above code and just add below code
app.use(bodyParser.json({ limit: "200mb" }));
app.use(bodyParser.urlencoded({ limit: "200mb", extended: true, parameterLimit: 1000000 }));
Visual Studio Code: Version 1.14.2 (1.14.2)
At default setting, you can see this:
// Columns at which to show vertical rulers
"editor.rulers": [],
This means the empty array won't show the vertical rulers.
At right window "user setting", add the following:
"editor.rulers": [140]
Save the file, and you will see the rulers.
You can use the output value from stat_summary()
ggplot(data=PlantGrowth, aes(x=group, y=weight, fill=group))
+ geom_boxplot()
+ stat_summary(fun.y=mean, colour="darkred", geom="point", hape=18, size=3,show_guide = FALSE)
+ stat_summary(fun.y=mean, colour="red", geom="text", show_guide = FALSE,
vjust=-0.7, aes( label=round(..y.., digits=1)))
Do it this way (make necessary changes in code)..
SqlConnection con = new SqlConnection(GetConnectionString());
con.Open();
SqlCommand cmd = new SqlCommand("CheckUser", con);
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter p1 = new SqlParameter("username", username.Text);
SqlParameter p2 = new SqlParameter("password", password.Text);
cmd.Parameters.Add(p1);
cmd.Parameters.Add(p2);
SqlDataReader rd = cmd.ExecuteReader();
if(rd.HasRows)
{
//do the things
}
else
{
lblinfo.Text = "abc";
}
Are you sure you aren't pushing over SSH? Maybe check the email associated with your SSH key in bitbucket if you have one.
It is worth noting that what you're doing isn't rounding, it's casting. Casting using (int) x
truncates the decimal value of x
. As in your example, if x = 3.9995
, the .9995
gets truncated and x = 3
.
As proposed by many others, one solution is to add 0.5
to x
, and then cast.
I have given simple JavaScript date format examples please check the bellow code
var data = new Date($.now()); // without jquery remove this $.now()
console.log(data)// Thu Jun 23 2016 15:48:24 GMT+0530 (IST)
var d = new Date,
dformat = [d.getFullYear() ,d.getMonth()+1,
d.getDate()
].join('-')+' '+
[d.getHours(),
d.getMinutes(),
d.getSeconds()].join(':');
console.log(dformat) //2016-6-23 15:54:16
Using momentjs
var date = moment().format('YYYY-MM-DD H:mm:ss');
console.log(date) // 2016-06-23 15:59:08
Example please check https://jsfiddle.net/sjy3vjwm/2/
Use empty
- http://php.net/manual/en/function.empty.php.
Example:
$a = '';
if(empty($a)) {
echo 'is empty';
}
From Java 7 onward you can use the try-with-resources statement to avoid leaking resources and make your code easier to read. More on that here.
To write your byteArray
to a file you would do:
try (FileOutputStream fos = new FileOutputStream("fullPathToFile")) {
fos.write(byteArray);
} catch (IOException ioe) {
ioe.printStackTrace();
}
To be clear and answer @Dean's question: EBS-type root storage doesn't seem to be ephemeral. Data is persistent across reboots and actually it doesn't make any sense to use ebs-backed root volume which is 'ephemeral'. This wouldn't be different from image-based root volume.
This meta tag is used by all responsive web pages, that is those that are designed to layout well across device types - phone, tablet, and desktop. The attributes do what they say. However, as MDN's Using the viewport meta tag to control layout on mobile browsers indicates,
On high dpi screens, pages with
initial-scale=1
will effectively be zoomed by browsers.
I've found that the following ensures that the page displays with zero zoom by default.
<meta name="viewport" content="width=device-width, initial-scale=0.86, maximum-scale=3.0, minimum-scale=0.86">
Simple: you can't.
