I would use list comprehension :
somelists = [
[1, 2, 3],
['a', 'b'],
[4, 5]
]
cart_prod = [(a,b,c) for a in somelists[0] for b in somelists[1] for c in somelists[2]]
Just check the string against this regex:
if(mystring.match(/^\s+$/) === null) {
alert("String is good");
} else {
alert("String contains only whitespace");
}
I had this problem, it is for foreign-key
Click on the Relation View
(like the image below) then find name of the field you are going to remove it, and under the Foreign key constraint (INNODB)
column, just put the select to nothing! Means no foreign-key
Hope that works!
For Android, and using Apache's Commons IO Library for IOUtils
:
// connection is a HttpURLConnection
InputStream inputStream = connection.getInputStream()
ByteArrayOutputStream baos = new ByteArrayOutputStream();
IOUtils.copy(inputStream, baos);
JSONObject jsonObject = new JSONObject(baos.toString()); // JSONObject is part of Android library
I also use Stefan Petre’s http://www.eyecon.ro/bootstrap-datepicker and it does not work with Bootstrap 3 without modification. Note that http://eternicode.github.io/bootstrap-datepicker/ is a fork of Stefan Petre's code.
You have to change your markup (the sample markup will not work) to use the new CSS and form grid layout in Bootstrap 3. Also, you have to modify some CSS and JavaScript in the actual bootstrap-datepicker implementation.
Here is my solution:
<div class="form-group row">
<div class="col-xs-8">
<label class="control-label">My Label</label>
<div class="input-group date" id="dp3" data-date="12-02-2012" data-date-format="mm-dd-yyyy">
<input class="form-control" type="text" readonly="" value="12-02-2012">
<span class="input-group-addon"><i class="glyphicon glyphicon-calendar"></i></span>
</div>
</div>
</div>
CSS changes in datepicker.css on lines 176-177:
.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {
Javascript change in datepicker-bootstrap.js on line 34:
this.component = this.element.is('.date') ? this.element.find('.input-group-addon') : false;
UPDATE
Using the newer code from http://eternicode.github.io/bootstrap-datepicker/ the changes are as follows:
CSS changes in datepicker.css on lines 446-447:
.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {
Javascript change in datepicker-bootstrap.js on line 46:
this.component = this.element.is('.date') ? this.element.find('.input-group-addon, .btn') : false;
Finally, the JavaScript to enable the datepicker (with some options):
$(".input-group.date").datepicker({ autoclose: true, todayHighlight: true });
Tested with Bootstrap 3.0 and JQuery 1.9.1. Note that this fork is better to use than the other as it is more feature rich, has localization support and auto-positions the datepicker based on the control position and window size, avoiding the picker going off the screen which was a problem with the older version.
Whenever changes are made in dockerfile or compose or requirements , re-Run it using docker-compose up --build
. So that images get rebuild and refreshed
console.log(document.getElementById('xx') ) evaluates to null.
document.getElementById('xx') !=null evaluates to false
You should use document.getElementById('xx') !== null
as it is a stronger equality check.
Following on @Kire Haglin's answer, a further example of generics methods can be seen in the documentation for JAXB unmarshalling:
public <T> T unmarshal( Class<T> docClass, InputStream inputStream )
throws JAXBException {
String packageName = docClass.getPackage().getName();
JAXBContext jc = JAXBContext.newInstance( packageName );
Unmarshaller u = jc.createUnmarshaller();
JAXBElement<T> doc = (JAXBElement<T>)u.unmarshal( inputStream );
return doc.getValue();
}
This allows unmarshal
to return a document of an arbitrary JAXB content tree type.
instead of receiving the json string a model binding is better. For example:
[HttpPost]
public ActionResult AddUser(UserAddModel model)
{
if (ModelState.IsValid) {
return Json(new { Response = "Success" });
}
return Json(new { Response = "Error" });
}
<script>
function submitForm() {
$.ajax({
type: 'POST',
url: "@Url.Action("AddUser")",
contentType: "application/json; charset=utf-8",
dataType: 'json',
data: $("form[name=UserAddForm]").serialize(),
success: function (data) {
console.log(data);
}
});
}
</script>
You can set the fontsize directly in the call to set_xticklabels
and set_yticklabels
(as noted in previous answers). This will only affect one Axes
at a time.
ax.set_xticklabels(x_ticks, rotation=0, fontsize=8)
ax.set_yticklabels(y_ticks, rotation=0, fontsize=8)
You can also set the ticklabel
font size globally (i.e. for all figures/subplots in a script) using rcParams
:
import matplotlib.pyplot as plt
plt.rc('xtick',labelsize=8)
plt.rc('ytick',labelsize=8)
Or, equivalently:
plt.rcParams['xtick.labelsize']=8
plt.rcParams['ytick.labelsize']=8
Finally, if this is a setting that you would like to be set for all your matplotlib plots, you could also set these two rcParams
in your matplotlibrc
file:
xtick.labelsize : 8 # fontsize of the x tick labels
ytick.labelsize : 8 # fontsize of the y tick labels
The most important difference to be aware of is that with a stream opened in text mode you get newline translation on non-*nix systems (it's also used for network communications, but this isn't supported by the standard library). In *nix newline is just ASCII linefeed, \n
, both for internal and external representation of text. In Windows the external representation often uses a carriage return + linefeed pair, "CRLF" (ASCII codes 13 and 10), which is converted to a single \n
on input, and conversely on output.
From the C99 standard (the N869 draft document), §7.19.2/2,
A text stream is an ordered sequence of characters composed into lines, each line consisting of zero or more characters plus a terminating new-line character. Whether the last line requires a terminating new-line character is implementation-defined. Characters may have to be added, altered, or deleted on input and output to conform to differing conventions for representing text in the host environment. Thus, there need not be a one- to-one correspondence between the characters in a stream and those in the external representation. Data read in from a text stream will necessarily compare equal to the data that were earlier written out to that stream only if: the data consist only of printing characters and the control characters horizontal tab and new-line; no new-line character is immediately preceded by space characters; and the last character is a new-line character. Whether space characters that are written out immediately before a new-line character appear when read in is implementation-defined.
And in §7.19.3/2
Binary files are not truncated, except as defined in 7.19.5.3. Whether a write on a text stream causes the associated file to be truncated beyond that point is implementation- defined.
About use of fseek
, in §7.19.9.2/4:
For a text stream, either
offset
shall be zero, oroffset
shall be a value returned by an earlier successful call to theftell
function on a stream associated with the same file andwhence
shall beSEEK_SET
.
About use of ftell
, in §17.19.9.4:
The
ftell
function obtains the current value of the file position indicator for the stream pointed to bystream
. For a binary stream, the value is the number of characters from the beginning of the file. For a text stream, its file position indicator contains unspecified information, usable by thefseek
function for returning the file position indicator for the stream to its position at the time of theftell
call; the difference between two such return values is not necessarily a meaningful measure of the number of characters written or read.
I think that’s the most important, but there are some more details.
So I was curious about the performance of some of the methods mentioned in the answers for large number of integers.
Just creating an array of 1 million random integers between 0 and 100. Than, I imploded them to get the string.
$integers = array();
for ($i = 0; $i < 1000000; $i++) {
$integers[] = rand(0, 100);
}
$long_string = implode(',', $integers);
This is the one liner from Mark's answer:
$integerIDs = array_map('intval', explode(',', $long_string));
This is the JSON approach:
$integerIDs = json_decode('[' . $long_string . ']', true);
I came up with this one as modification of Mark's answer. This is still using explode()
function, but instead of calling array_map()
I'm using regular foreach
loop to do the work to avoid the overhead array_map()
might have. I am also parsing with (int)
vs intval()
, but I tried both, and there is not much difference in terms of performance.
$result_array = array();
$strings_array = explode(',', $long_string);
foreach ($strings_array as $each_number) {
$result_array[] = (int) $each_number;
}
Results:
Method 1 Method 2 Method 3
0.4804770947 0.3608930111 0.3387751579
0.4748001099 0.363986969 0.3762528896
0.4625790119 0.3645150661 0.3335959911
0.5065748692 0.3570590019 0.3365750313
0.4803431034 0.4135499001 0.3330330849
0.4510772228 0.4421861172 0.341176033

0.4863037268 0.3742785454 0.3488383293
The bottom line is the average. It looks like the first method was a little slower for 1 million integers, but I didn't notice 3x performance gain of Method 2 as stated in the answer. It turned out foreach
loop was the quickest one in my case. I've done the benchmarking with Xdebug.
Edit: It's been a while since the answer was originally posted. To clarify, the benchmark was done in php 5.6.
As far as i understand fr is the object of your FileReadExample class. So it is obvious it will not have any method like fr.readLine() if you dont create one yourself.
secondly, i think a correct constructor of the BufferedReader class will help you do your task.
String str;
BufferedReader buffread = new BufferedReader(new FileReader(new File("file.dat")));
str = buffread.readLine();
.
.
buffread.close();
this should help you.
You could also put non-breaking spaces (&nbsp;) in lieu of the spaces so that they're forced to stay together.
How do I wrap this line of text
- asked by Peter 2 days ago
FWIW with Ansible 2.2 one can use include_role:
playbook test.yml
:
- name: test
hosts:
- 127.0.0.1
connection: local
tasks:
- include_role:
name: test
tasks_from: other
then in roles/test/tasks/other.yml
:
- name: say something else
shell: echo "I'm the other guy"
And invoke the playbook with: ansible-playbook test.yml
to get:
TASK [test : say something else] *************
changed: [127.0.0.1]
I searched for the solution how I can insert a new row and How to set the individual values of the cells inside it like Excel. I solved with following code:
dataGridView1.ReadOnly = false; //Before modifying, it is required.
dataGridView1.Rows.Add(); //Inserting first row if yet there is no row, first row number is '0'
dataGridView1.Rows[0].Cells[0].Value = "Razib, this is 0,0!"; //Setting the leftmost and topmost cell's value (Not the column header row!)
dataGridView1[1, 0].Value = "This is 0,1!"; //Setting the Second cell of the first row!
Note:
Hope this might help you.
The default data directory for MongoDB is /data/db
.
This can be overridden by a dbpath
option specified on the command line or in a configuration file.
If you install MongoDB via a package manager such as Homebrew or MacPorts these installs typically create a default data directory other than /data/db and set the dbpath in a configuration file.
If a dbpath was provided to mongod
on startup you can check the value in the mongo
shell:
db.serverCmdLineOpts()
You would see a value like:
"parsed" : {
"dbpath" : "/usr/local/data"
},
you can use serialize method of jquery to get form values. Try like this
<form action="target.php" method="post" >
<input type="text" name="lname" />
<input type="text" name="fname" />
<input type="buttom" name ="send" onclick="return f(this.form) " >
</form>
function f( form ){
var formData = $(form).serialize();
att=form.attr("action") ;
$.post(att, formData).done(function(data){
alert(data);
});
return true;
}
These two commands should do it:
:set autoindent
:set cindent
For bonus points put them in a file named .vimrc located in your home directory on linux
declare @tab table(FirstName varchar(100))
insert into @tab values('John'),('Sarah'),('George')
SELECT *
FROM @tab
WHERE 'John' in (FirstName)
The problem will be that you cannot represent 0.575 exactly as a binary floating point number (eg a double). Though I don't know exactly it seems that the representation closest is probably just a bit lower and so when rounding it uses the true representation and rounds down.
If you want to avoid this problem then use a more appropriate data type. decimal
will do what you want:
Math.Round(0.575M, 2, MidpointRounding.AwayFromZero)
Result: 0.58
The reason that 0.75 does the right thing is that it is easy to represent in binary floating point since it is simple 1/2 + 1/4 (ie 2^-1 +2^-2). In general any finite sum of powers of two can be represented in binary floating point. Exceptions are when your powers of 2 span too great a range (eg 2^100+2 is not exactly representable).
Edit to add:
Formatting doubles for output in C# might be of interest in terms of understanding why its so hard to understand that 0.575 is not really 0.575. The DoubleConverter in the accepted answer will show that 0.575 as an Exact String is 0.5749999999999999555910790149937383830547332763671875
You can see from this why rounding give 0.57.

After 2.10, to solve the scope problem, you can do something like this:
{% set count = namespace(value=0) %}
{% for i in p %}
{{ count.value }}
{% set count.value = count.value + 1 %}
{% endfor %}
Well first you try to assign strings not chars, even if they are just one character. use ',' instead of ",". Next thing is, enums only take integral types without char
you could use the unicode value, but i would strongly advice you not to do so.
If you are certain that these values stay the same, in differnt cultures and languages, i would use a static class with const strings.
With angular cli
npm install angular-material-icons --save
or
npm install material-design-icons-iconfont --save
material-design-icons-iconfont is the latest updated version of the icons. angular-material-icons is not updated for a long time
Wait wait wait install to be done and then add it to angular.json -> projects -> architect -> styles
"styles": [
"node_modules/material-design-icons/iconfont/material-icons.css",
"src/styles.scss"
],
or if you installed material-desing-icons-iconfont then
"styles": [
"node_modules/material-design-icons-iconfont/dist/material-design-icons.css",

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminateTintMode="src_atop"
android:indeterminateTint="@color/your_customized_color"
android:layout_gravity="center" />
The effect looks like this:
public void paintComponent (Graphics g)
{
((Graphics2D) g).setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER,0.0f)); // draw transparent background
super.paintComponent(g);
((Graphics2D) g).setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER,1.0f)); // turn on opacity
g.setColor(Color.RED);
g.fillRect(20, 20, 500, 300);
}
I have tried to do it this way, but it is very flickery
You could use a projection with a statement lambda, but the original foreach
loop is more readable and is editing the list in place rather than creating a new list.
var result = list.Select(i =>
{
if (i.Name == "height") i.Value = 30;
return i;
}).ToList();
Extension Method
public static IEnumerable<MyClass> SetHeights(
this IEnumerable<MyClass> source, int value)
{
foreach (var item in source)
{
if (item.Name == "height")
{
item.Value = value;
}
yield return item;
}
}
var result = list.SetHeights(30).ToList();
Try this.
public class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API configuration and services
var json = config.Formatters.JsonFormatter;
json.SupportedMediaTypes.Add(new System.Net.Http.Headers.MediaTypeHeaderValue("application/json"));
config.Formatters.Remove(config.Formatters.XmlFormatter);
// Web API routes
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional , Action =RouteParameter.Optional }
);
}
}
Simple solution without autofocus:
<input ref={ref => ref && ref.focus()}
onFocus={(e)=>e.currentTarget.setSelectionRange(e.currentTarget.value.length, e.currentTarget.value.length)}
/>
ref
triggers focus, and that triggers onFocus
to calculate the end and set the cursor accordingly.
I was very impressed by compact JSON formatter by Vince Panuccio.
Here is an improved version I now use:
public static string FormatJson(string json, string indent = " ")
{
var indentation = 0;
var quoteCount = 0;
var escapeCount = 0;
var result =
from ch in json ?? string.Empty
let escaped = (ch == '\\' ? escapeCount++ : escapeCount > 0 ? escapeCount-- : escapeCount) > 0
let quotes = ch == '"' && !escaped ? quoteCount++ : quoteCount
let unquoted = quotes % 2 == 0
let colon = ch == ':' && unquoted ? ": " : null
let nospace = char.IsWhiteSpace(ch) && unquoted ? string.Empty : null
let lineBreak = ch == ',' && unquoted ? ch + Environment.NewLine + string.Concat(Enumerable.Repeat(indent, indentation)) : null
let openChar = (ch == '{' || ch == '[') && unquoted ? ch + Environment.NewLine + string.Concat(Enumerable.Repeat(indent, ++indentation)) : ch.ToString()
let closeChar = (ch == '}' || ch == ']') && unquoted ? Environment.NewLine + string.Concat(Enumerable.Repeat(indent, --indentation)) + ch : ch.ToString()
select colon ?? nospace ?? lineBreak ?? (
openChar.Length > 1 ? openChar : closeChar
);
return string.Concat(result);
}
It fixes the following issues:

Both John Conde's and ryeballar's answers are correct and will work.
If you want to get too geeky:
John's has the downside that it has to make two decisions per $digest loop (it has to decide whether to add/remove center
and it has to decide whether to add/remove left
), when clearly only one is needed.
Ryeballar's relies on the ternary operator which is probably going to be removed at some point (because the view should not contain any logic). (We can't be sure it will indeed be removed and it probably won't be any time soon, but if there is a more "safe" solution, why not ?)
So, you can do the following as an alternative:
ng-class="{true:'center',false:'left'}[page.isSelected(1)]"
If you instead had a data.frame (df) that had multiple columns and you want to vectorize you can do
as.matrix(df, ncol=1)
Create a temporary element, then clone()
and append()
:
$('<div>').append($('#xxx').clone()).html();
The JDK 8 HotSpot JVM is now using native memory for the representation of class metadata and is called Metaspace.
The permanent generation has been removed. The PermSize
and MaxPermSize
are ignored and a warning is issued if they are present on the command line.
If I remember correctly, you'll need to set the netbeans_jdkhome
property in your netbeans config file. Should be in your etc/netbeans.conf
file.
Keep both lists x and y in sorted order.
If x = y, do your action, if x < y, advance x, if y < x, advance y until either list is empty.
The run time of this intersection is proportional to min (size (x), size (y))
Don't run a .Contains () loop, this is proportional to x * y which is much worse.
The advantage of Java 1.8 forEach method over 1.7 Enhanced for loop is that while writing code you can focus on business logic only.
forEach method takes java.util.function.Consumer object as an argument, so It helps in having our business logic at a separate location that you can reuse it anytime.
Have look at below snippet,
Here I have created new Class that will override accept class method from Consumer Class, where you can add additional functionility, More than Iteration..!!!!!!
class MyConsumer implements Consumer<Integer>{
@Override
public void accept(Integer o) {
System.out.println("Here you can also add your business logic that will work with Iteration and you can reuse it."+o);
}
}
public class ForEachConsumer {
public static void main(String[] args) {
// Creating simple ArrayList.
ArrayList<Integer> aList = new ArrayList<>();
for(int i=1;i<=10;i++) aList.add(i);
//Calling forEach with customized Iterator.
MyConsumer consumer = new MyConsumer();
aList.forEach(consumer);
// Using Lambda Expression for Consumer. (Functional Interface)
Consumer<Integer> lambda = (Integer o) ->{
System.out.println("Using Lambda Expression to iterate and do something else(BI).. "+o);
};
aList.forEach(lambda);
// Using Anonymous Inner Class.
aList.forEach(new Consumer<Integer>(){
@Override
public void accept(Integer o) {
System.out.println("Calling with Anonymous Inner Class "+o);

If I understand your questions correctly, all you need to do is add the .Where(m => m.r.u.UserId == 1):
var UserInRole = db.UserProfiles.
Join(db.UsersInRoles, u => u.UserId, uir => uir.UserId,
(u, uir) => new { u, uir }).
Join(db.Roles, r => r.uir.RoleId, ro => ro.RoleId, (r, ro) => new { r, ro })
.Where(m => m.r.u.UserId == 1)
.Select (m => new AddUserToRole
{
UserName = m.r.u.UserName,
RoleName = m.ro.RoleName
});
Hope that helps.
Okay, how about a CSS answer! We use display: table
. Then each of the divs are rows, and finally we apply height of 100% to middle 'row' and voilà.
body { display: table; }
div { display: table-row; }
#content {
width:450px;
margin:0 auto;
text-align: center;
background-color: blue;
color: white;
height: 100%;
}
@unutbu's answer is quite close to the right answer.
By default, plt.imshow() will try to scale your (MxN) array data to 0.0~1.0. And then map to 0~255. For most natural taken images, this is fine, you won't see a different. But if you have narrow range of pixel value image, say the min pixel is 156 and the max pixel is 234. The gray image will looks totally wrong. The right way to show an image in gray is
from matplotlib.colors import NoNorm
...
plt.imshow(img,cmap='gray',norm=NoNorm())
...
Let's see an example:
this is the origianl image: original
this is using defaul norm setting,which is None: wrong pic
this is using NoNorm setting,which is NoNorm(): right pic
Same origin policy has nothing to do with sending request to another url (different protocol or domain or port).
It is all about restricting access to (reading) response data from another url. So JavaScript code within a page can post to arbitrary domain or submit forms within that page to anywhere (unless the form is in an iframe with different url).
But what makes these POST requests inefficient is that these requests lack antiforgery tokens, so are ignored by the other url. Moreover, if the JavaScript tries to get that security tokens, by sending AJAX request to the victim url, it is prevented to access that data by Same Origin Policy.
A good example: here
And a good documentation from Mozilla: here
Andrew had a great response but I wanted to tweek it a little. The way this is different is that I like my ModelViews to not have overhead data in them. Just the data for the object. It seem that ViewData fits the bill for over head data, but of course I'm new at this. I suggest doing something like this.
Controller
virtual public ActionResult DisplaySomeWidget(int id)
{
SomeModelView returnData = someDataMapper.getbyid(1);
var serializer = new JavaScriptSerializer();
ViewData["JSON"] = serializer.Serialize(returnData);
return View(myview, returnData);
}
View
//create base js object;
var myWidget= new Widget(); //Widget is a class with a public member variable called data.
myWidget.data= <%= ViewData["JSON"] %>;
What This does for you is it gives you the same data in your JSON as in your ModelView so you can potentially return the JSON back to your controller and it would have all the parts. This is similar to just requesting it via a JSONRequest however it requires one less call so it saves you that overhead. BTW this is funky for Dates but that seems like another thread.
What worked for me (I looked all over the place and ended up using someone's jsfiddler / very slightly modifying it - worked nicely) was to set that variable to an object with a getter and setter, and the setter triggers the function that is waiting for variable change.
var myVariableImWaitingOn = function (methodNameToTriggerWhenChanged){
triggerVar = this;
triggerVar.val = '';
triggerVar.onChange = methodNameToTriggerWhenChanged;
this.SetValue(value){
if (value != 'undefined' && value != ''){
triggerVar.val = value; //modify this according to what you're passing in -
//like a loop if an array that's only available for a short time, etc
triggerVar.onChange(); //could also pass the val to the waiting function here
//or the waiting function can just call myVariableImWaitingOn.GetValue()
}
};
this.GetValue(){
return triggerVar.val();
};
};
You need to use a while loop. If you make a while loop, and there's no instruction after the loop, it'll become an infinite loop,and won't stop until you manually stop it.
Open application if it is exist, or open Play Store application for install it:
private void open() {
openApplication(getActivity(), "com.app.package.here");
}
public void openApplication(Context context, String packageN) {
Intent i = context.getPackageManager().getLaunchIntentForPackage(packageN);
if (i != null) {
i.addCategory(Intent.CATEGORY_LAUNCHER);
context.startActivity(i);
} else {
try {
context.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + packageN)));
}
catch (android.content.ActivityNotFoundException anfe) {
context.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=" + packageN)));

The difference between:
parser.add_argument("--debug", help="Debug", nargs='?', type=int, const=1, default=7)
and
parser.add_argument("--debug", help="Debug", nargs='?', type=int, const=1)
is thus:
myscript.py
=> debug is 7 (from default) in the first case and "None" in the second
myscript.py --debug
=> debug is 1 in each case
myscript.py --debug 2
=> debug is 2 in each case
A float isn't have 0
or 0.00
: those are different string representations of the internal (IEEE754) binary format but the float is the same.
If you want to express your float as "0.00", you need to format it in a string, using number_format :
$numberAsString = number_format($numberAsFloat, 2);
I know this is an old question, but here is my contribution. Instead of all these tricks, you can just simply wrap a function inside another function. Like I have done here:
<div data-bind="click: function(){ f('hello parameter'); }">Click me once</div>
<div data-bind="click: function(){ f('no no parameter'); }">Click me twice</div>
var VM = function(){
this.f = function(param){
console.log(param);
}
}
ko.applyBindings(new VM());
And here is the fiddle
Maybe I am missing something here, but did you allocate any memory for that PString before you accessed it?
PString * initializeString() {
PString *str;
str = (PString *) malloc(sizeof(PString));
str->length = &length;
return str;
}

I had a similar problem what worked for me was to set JAVA_HOME. I tired it first in R:
Sys.setenv(JAVA_HOME = "C:/Program Files/Java/jdk1.8.0_101/")
And when it actually worked I set it in
System Properties -> Advanced -> Environment Variables
by adding a new System variable. I then restarted R/RStudio and everything worked.
If you are using Angular (2+), (or any other framework), you could add some logic. The logic would be: only display an empty option if the user did not select any other yet. So after the user selected an option, the empty option disappears.
For Angular (9) this would look something like this:
<select>
<option *ngIf="(hasOptionSelected$ | async) === false"></option>
<option *ngFor="let option of (options$ | async)[value]="option.id">{{ option.title }}</option>
</select>
It should look like this:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument('--headless')
options.add_argument('--disable-gpu') # Last I checked this was necessary.
driver = webdriver.Chrome(CHROMEDRIVER_PATH, chrome_options=options)
This works for me using Python 3.6, I'm sure it'll work for 2.7 too.
Update 2018-10-26: These days you can just do this:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.headless = True
driver = webdriver.Chrome(CHROMEDRIVER_PATH, chrome_options=options)
I spent most of a day trying all the solutions here, but nothing seemed to work. The only thing that worked for me was to completely uninstall IntelliJ and install it again. However, for me, when I deleted IntelliJ from the Application folder, the problem returned as soon as I re-installed it. What I finally had to do was to use App Cleaner to completely remove IntelliJ and all the config and settings files. After I did that and then reinstalled IntelliJ, the problem finally went away. See How to uninstall IntelliJ on a Mac
You can't include server side PHP in your client side javascript, you will have to port it over to javascript. If you wish, you can use php.js, which ports all PHP functions over to javascript. You can also create a new php file that returns the results of calling your PHP function, and then call that file using AJAX to get the results.

I upgraded VS2017 from version 15.2 to 15.8. With version 15.8 here's what happened:
Project -> Properties -> General -> Windows SDK Version -> select 10.0.15063.0 no longer worked for me! I had to change it to 10.0.17134.0 and then everything built again. After the upgrade and without making this change, I was getting the same header file errors.
I would have submitted this as a comment on one of the other answers but I don't have enough reputation yet.
If you want it to be used on many platforms, you could as commented use defines like:

After reading many of the answers, I feel the need to add something:
Strict aliasing (which I'll describe in a bit) is important because:
Memory access can be expensive (performance wise), which is why data is manipulated in CPU registers before being written back to the physical memory.
If data in two different CPU registers will be written to the same memory space, we can't predict which data will "survive" when we code in C.
In assembly, where we code the loading and unloading of CPU registers manually, we will know which data remains intact. But C (thankfully) abstracts this detail away.
Since two pointers can point to the same location in the memory, this could result in complex code that handles possible collisions.
This extra code is slow and hurts performance since it performs extra memory read / write operations which are both slower and (possibly) unnecessary.
The Strict aliasing rule allows us to avoid redundant machine code in cases in which it should be safe to assume that two pointers don't point to the same memory block (see also the restrict
keyword).
The Strict aliasing states it's safe to assume that pointers to different types point to different locations in the memory.
If a compiler notices that two pointers point to different types (for example, an int *
and a float *
), it will assume the memory address is different and it will not protect against memory address collisions, resulting in faster machine code.
For example:
Lets assume the following function:
void merge_two_ints(int *a, int *b) {
*b += *a;
*a += *b;
}
In order to handle the case in which a == b
(both pointers point to the same memory), we need to order and test the way we load data from the memory to the CPU registers, so the code might end up like this:
load a
and b
from memory.
add a
to b
.
save b
and reload a
.
(save from CPU register to the memory and load from the memory to the CPU register).
add b
to a
.
save a
(from the CPU register) to the memory.
Step 3 is very slow because it needs to access the physical memory. However, it's required to protect against instances where a
and b
point to the same memory address.
Strict aliasing would allow us to prevent this by telling the compiler that these memory addresses are distinctly different (which, in this case, will allow even further optimization which can't be performed if the pointers share a memory address).
This can be told to the compiler in two ways, by using different types to point to. i.e.:
void merge_two_numbers(int *a, long *b) {...}
Using the restrict
keyword. i.e.:
void merge_two_ints(int * restrict a, int * restrict b) {...}
Now, by satisfying the Strict Aliasing rule, step 3 can be avoided and the code will run significantly faster.
In fact, by adding the restrict
keyword, the whole function could be optimized to:
load a
and b
from memory.
add a
to b
.
save result both to a
and to b
.
This optimization couldn't have been done before, because of the possible collision (where a
and b
would be tripled instead of doubled).

For cookies that I am explicitly setting, I switched to use SimpleCookie provided by Apache Shiro. It does not inherit from javax.servlet.http.Cookie so it takes a bit more juggling to get everything to work correctly however it does provide a property set HttpOnly and it works with Servlet 2.5.
For setting a cookie on a response, rather than doing response.addCookie(cookie)
you need to do cookie.saveTo(request, response)
.
I am new to ruby and had to just deal with understanding the following weirdness. Might help out someone else in the future. In the end it is as was mentioned above, where 2 functions (def myvar, def myvar=) both get implicitly for accessing @myvar, but these methods can be overridden by local declarations.
class Foo
attr_accessor 'myvar'
def initialize
@myvar = "A"
myvar = "B"
puts @myvar # A
puts myvar # B - myvar declared above overrides myvar method
end
def test
puts @myvar # A
puts myvar # A - coming from myvar accessor
myvar = "C" # local myvar overrides accessor
puts @myvar # A
puts myvar # C
send "myvar=", "E" # not running "myvar =", but instead calls setter for @myvar
puts @myvar # E
puts myvar # C
end
end
On the flip side, I was having an issue with PHPUNIT asserting urls was contained in or equal to a url that was json_encoded -
my expected:
http://localhost/api/v1/admin/logs/testLog.log
would be encoded to:
http:\/\/localhost\/api\/v1\/admin\/logs\/testLog.log
If you need to do a comparison, transforming the url using:
addcslashes($url, '/')
allowed for the proper output during my comparisons.
I think the DocumentCompleted event of the WebBrowser control should get you where you need to go.
Here's a snippet of hql that we use. (Names have been changed to protect identities)
String queryString = "select distinct f from Foo f inner join foo.bars as b" +
" where f.creationDate >= ? and f.creationDate < ? and b.bar = ?";
return getHibernateTemplate().find(queryString, new Object[] {startDate, endDate, bar});
use jQuery.live() instead . Documentation here
e.g
$("mylink").live("click", function(event) { alert("new link clicked!");});
Starting Mongo 4.2
, db.collection.update()
can accept an aggregation pipeline, which allows using aggregation operators such as $addFields
, which outputs all existing fields from the input documents and newly added fields:
var new_info = { param2: "val2_new", param3: "val3_new" }
// { some_key: { param1: "val1", param2: "val2", param3: "val3" } }
// { some_key: { param1: "val1", param2: "val2" } }
db.collection.update({}, [{ $addFields: { some_key: new_info } }], { multi: true })
// { some_key: { param1: "val1", param2: "val2_new", param3: "val3_new" } }
// { some_key: { param1: "val1", param2: "val2_new", param3: "val3_new" } }
The first part {}
is the match query, filtering which documents to update (in this case all documents).
The second part [{ $addFields: { some_key: new_info } }]
is the update aggregation pipeline:
$addFields
.$addFields
performs exactly what you need: updating the object so that the new object will overlay / merge with the existing one:{ param2: "val2_new", param3: "val3_new" }
will be merged into the existing some_key
by keeping param1
untouched and either add or replace both param2
and param3
.Don't forget { multi: true }
, otherwise only the first matching document will be updated.
When Visual Studio prompted me for Visual Studio Team Services credentials there are two options:
In my situation I was using a work email address, however, I had to select "Personal" in order to get connected. Selecting "Work or School" gave me the "tf30063 you are not authorized to access..." error.
For some reason my email address appears to be registered as "personal" even though everything is setup in Office 365 / Azure as a company. I believe the Microsoft account was created prior to our Silver Partnership status with Microsoft.
This worked for me... try it
let image : UIImage = UIImage(named: "LogoName")
let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 25, height: 25))
imageView.contentMode = .scaleAspectFit
imageView.image = image
navigationItem.titleView = imageView
I am reading a text file and want to use regex below to pull out numbers with exactly 5 digit, ignoring alphabets.
Try this...
var str = 'f 34 545 323 12345 54321 123456',
matches = str.match(/\b\d{5}\b/g);
console.log(matches); // ["12345", "54321"]
The word boundary \b
is your friend here.
My regex will get a number like this 12345
, but not like a12345
. The other answers provide great regexes if you require the latter.
well for what its worth now... JsonProperty is ALSO used to specify getter and setter methods for the variable apart from usual serialization and deserialization. For example suppose you have a payload like this:
{
"check": true
}
and a Deserializer class:
public class Check {
@JsonProperty("check") // It is needed else Jackson will look got getCheck method and will fail
private Boolean check;
public Boolean isCheck() {
return check;
}
}
Then in this case JsonProperty annotation is neeeded. However if you also have a method in the class
public class Check {
//@JsonProperty("check") Not needed anymore
private Boolean check;
public Boolean getCheck() {
return check;
}
}
Have a look at this documentation too: http://fasterxml.github.io/jackson-annotations/javadoc/2.3.0/com/fasterxml/jackson/annotation/JsonProperty.html
Well I was searching for an easy way. And find out on medium.
First to copy the json text and validate it on jsonlint or something similar. Then to copy from jsonlint, already the json is formatted. And paste the code on Xcode with preserving the format, shortcut shift + option + command + v
Best strategy is to design your site to build a unique URL to your JS files, that gets reset every time there is a change. That way it caches when there has been no change, but imediately reloads when any change occurs.
You'd need to adjust for your specific environment tools, but if you are using PHP/Apache, here's a great solution for both you, and the end-users.

we starting from conversion [ JSONArray -> List < JSONObject > ]
public static List<JSONObject> getJSONObjectListFromJSONArray(JSONArray array)
throws JSONException {
ArrayList<JSONObject> jsonObjects = new ArrayList<>();
for (int i = 0;
i < (array != null ? array.length() : 0);
jsonObjects.add(array.getJSONObject(i++))
);
return jsonObjects;
}
next create generic version replacing array.getJSONObject(i++) with POJO
example :
public <T> static List<T> getJSONObjectListFromJSONArray(Class<T> forClass, JSONArray array)
throws JSONException {
ArrayList<Tt> tObjects = new ArrayList<>();
for (int i = 0;
i < (array != null ? array.length() : 0);
tObjects.add( (T) createT(forClass, array.getJSONObject(i++)))
);
return tObjects;
}
private static T createT(Class<T> forCLass, JSONObject jObject) {
// instantiate via reflection / use constructor or whatsoever
T tObject = forClass.newInstance();
// if not using constuctor args fill up
//
// return new pojo filled object
return tObject;
}
au, nz, ie, etc. are the country codes for the countries whose national days are being displayed (Australia, New Zealand, Ireland, ...). As seen in the code, these values are combined with '_day' and passed back to be applied to that day as a CSS style. The corresponding styles are of the form show below, which moves the text for that day out of the way and replaces it with an image of the country's flag.
.au_day {
text-indent: -9999px;
background: #eee url(au.gif) no-repeat center;
}
The 'false' value that is passed back with the new style indicates that these days may not be selected.
No. It is not possible via CSS. It takes the "Cascade" to heart ;-).
However, if you are able to add JavaScript to your page, a little bit of jQuery could get you to your end goal.
You can use jQuery's find
to perform a "look-ahead" on your target element/class/id, then backtrack to select your target.
Then you use jQuery to re-write the DOM (CSS) for your element.
Based on this answer by Mike Brant, the following jQuery snippet could help.
$('p + ul').prev('p')
This first selects all <ul>
s that immediately follow a <p>
.
Then it "backtracks" to select all the previous <p>
s from that set of <ul>
s.
Effectively, "previous sibling" has been selected via jQuery.
Now, use the .css
function to pass in your CSS new values for that element.
In my case I was looking to find a way to select a DIV with the id #full-width
, but ONLY if it had a (indirect) descendant DIV with the class of .companies
.
I had control of all the HTML under .companies
, but could not alter any of the HTML above it.
And the cascade goes only 1 direction: down.
Thus I could select ALL #full-width
s.
Or I could select .companies
that only followed a #full-width
.
But I could not select only #full-width
s that proceeded .companies
.
And, again, I was unable to add .companies
any higher up in the HTML. That part of the HTML was written externally, and wrapped our code.
But with jQuery, I can select the required #full-width
s, then assign the appropriate style:
$("#full-width").find(".companies").parents("#full-width").css( "width", "300px" );
This finds all #full-width .companies
, and selects just those .companies
, similar to how selectors are used to target specific elements in standard in CSS.
Then it uses .parents
to "backtrack" and select ALL parents of .companies
,
but filters those results to keep only #fill-width
elements, so that in the end,
it only selects a #full-width
element if it has a .companies
class descendant.
Finally, it assigns a new CSS (width
) value to the resulting element.
$(".parent").find(".change-parent").parents(".parent").css( "background-color", "darkred");

jQuery Reference Docs:
$() or jQuery(): DOM element.
.find: Get the descendants of each element in the current set of matched elements, filtered by a selector, jQuery object, or element.
.parents: Get the immediately preceding sibling of each element in the set of matched elements. If a selector is provided, it retrieves the previous sibling only if it matches that selector (filters the results to only include the listed elements/selectors).
.css: Set one or more CSS properties for the set of matched elements.
Try this. While this still uses eval, it only uses it to summon the function from the current context. Then, you have the real function to use as you wish.
The main benefit for me from this is that you will get any eval-related errors at the point of summoning the function. Then you will get only the function-related errors when you call.
def say_hello(name):
print 'Hello {}!'.format(name)
# get the function by name
method_name = 'say_hello'
method = eval(method_name)
# call it like a regular function later
args = ['friend']
kwargs = {}
method(*args, **kwargs)

Think of it like this: the List
interface has methods like add(int index, E element)
, set(int index, E element)
. The contract is that once you added an element at position X you will find it there unless you add or remove elements before it.
If any list implementation would store elements in some order other than based on the index, the above list methods would make no sense.

Paging Logic
public Pagination GetCategoryPaging(int currentPage, int recordCount, string query)
{
string pageClass = string.Empty; int pageSize = 10, innerCount = 5;
Pagination pagination = new Pagination();
pagination.Pages = new List<PageEntity>();
pagination.Next = currentPage + 1;
pagination.Previous = ((currentPage - 1) > 0) ? (currentPage - 1) : 1;

Using Controller
public ActionResult GetPages()

if (!string.IsNullOrEmpty(Request.QueryString["page"]))
{

}
if (!string.IsNullOrEmpty(Request.QueryString["q"]))
{

}
/* to be Fetched from database using count */
int recordCount = 100;
Place place = new Place();
Pagination pagination = place.GetCategoryPaging(currentPage, recordCount, search);
return PartialView("Controls/_Pagination", pagination);
}
Similar to this question.
In essence it means that the method Bar
will not modify non mutable member variables of Foo
.
I'm a bit late it seems to be, but...
a='hello'
print list(a)
# ['h','e','l','l', 'o']
This is really a square peg, round hole question.
If relational databases and SQL are the only hammer you have or are willing to use, then the answers that have been posted thus far are adequate. However, why not use a tool designed to handle hierarchical data? Graph database are ideal for complex hierarchical data.
The inefficiencies of the relational model along with the complexities of any code/query solution to map a graph/hierarchical model onto a relational model is just not worth the effort when compared to the ease with which a graph database solution can solve the same problem.
Consider a Bill of Materials as a common hierarchical data structure.
class Component extends Vertex {
long assetId;
long partNumber;
long material;
long amount;
};
class PartOf extends Edge {
};
class AdjacentTo extends Edge {
};
Shortest path between two sub-assemblies: Simple graph traversal algorithm. Acceptable paths can be qualified based on criteria.
Similarity: What is the degree of similarity between two assemblies? Perform a traversal on both sub-trees computing the intersection and union of the two sub-trees. The percent similar is the intersection divided by the union.
Transitive Closure: Walk the sub-tree and sum up the field(s) of interest, e.g. "How much aluminum is in a sub-assembly?"
Yes, you can solve the problem with SQL and a relational database. However, there are much better approaches if you are willing to use the right tool for the job.
If you want all the li tags in an array even when they are in different ul tags then you can simply do
var lis = document.getElementByTagName('li');
and if you want to get particular div tag li's then:
var lis = document.getElementById('divID').getElementByTagName('li');
else if you want to search a ul first and then its li tags then you can do:
var uls = document.getElementsByTagName('ul');
for(var i=0;i<uls.length;i++){
var lis=uls[i].getElementsByTagName('li');
for(var j=0;j<lis.length;j++){
console.log(lis[j].innerHTML);
}
}
From search engines, I ended up on this topic for non-json posting data with fetch, so thought I would add this.
For non-json you don't have to use form data. You can simply set the Content-Type
header to application/x-www-form-urlencoded
and use a string:
fetch('url here', {
method: 'POST',
headers: {'Content-Type':'application/x-www-form-urlencoded'}, // this line is important, if this content-type is not set it wont work
body: 'foo=bar&blah=1'
});
An alternative way to build that body
string, rather then typing it out as I did above, is to use libraries. For instance the stringify
function from query-string
or qs
packages. So using this it would look like:
import queryString from 'query-string'; // import the queryString class
fetch('url here', {
method: 'POST',
headers: {'Content-Type':'application/x-www-form-urlencoded'}, // this line is important, if this content-type is not set it wont work
body: queryString.stringify({for:'bar', blah:1}) //use the stringify object of the queryString class
});
Like you said since the xpath for the next button is the same on every page it won't work. It's working as coded in that it does wait for the element to be displayed but since it's already displayed then the implicit wait doesn't apply because it doesn't need to wait at all. Why don't you use the fact that the url changes since from your code it appears to change when the next button is clicked. I do C# but I guess in Java it would be something like:
WebDriver driver = new FirefoxDriver();
String startURL = //a starting url;
String currentURL = null;
WebDriverWait wait = new WebDriverWait(driver, 10);
foo(driver,startURL);
/* go to next page */
if(driver.findElement(By.xpath("//*[@id='someID']")).isDisplayed()){
String previousURL = driver.getCurrentUrl();
driver.findElement(By.xpath("//*[@id='someID']")).click();
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
ExpectedCondition e = new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver d) {
return (d.getCurrentUrl() != previousURL);
}
};
wait.until(e);
currentURL = driver.getCurrentUrl();
System.out.println(currentURL);
}
You can convert using different methods
List<Element> list = Arrays.asList(array);
List<Element> list = new ArrayList();
Collections.addAll(list, array);
Arraylist list = new Arraylist();
list.addAll(Arrays.asList(array));
For more detail you can refer to http://javarevisited.blogspot.in/2011/06/converting-array-to-arraylist-in-java.html
I'm so late to answer this problem, so I figure it out. Just use,
android:gravity="center_horizontal"
That's because the browser doesn't transmit that part to the server, sorry.
Round towards negative infinity - Math.floor()
+3.5 => +3.0
-3.5 => -4.0
Round towards zero can be done using Math.trunc()
. Older browsers do not support this function. If you need to support these, you can use Math.ceil()
for negative numbers and Math.floor()
for positive numbers.
+3.5 => +3.0 using Math.floor()
-3.5 => -3.0 using Math.ceil()
You can run the web server on any port. 80 is just convention as are 8080 (web server on unprivileged port) and 443 (web server + ssl). However if you're looking to see some web site by pointing your browser to a different port you're probably out of luck. Unless the web server is being run on that port explicitly you'll just get an error message.
If you want to disable editing the entire grid, you can set IsReadOnly to true on the grid. If you want to disable user to add new rows, you set the property CanUserAddRows="False"
<DataGrid IsReadOnly="True" CanUserAddRows="False" />
Further more you can set IsReadOnly on individual columns to disable editing.
this is how I do it
function run_ajax(obj) {
$.ajax({
type:"POST",
url: prefix,
data: obj.pdata,
dataType: 'json',
error: function(data) {
//do error stuff
},
success: function(data) {
if(obj.func){
obj.func(data);
}
}
});
}
alert_func(data){
//do what you want with data
}
var obj= {};
obj.pdata = {sumbit:"somevalue"}; // post variable data
obj.func = alert_func;
run_ajax(obj);
if you have a data frame and want to remove all duplicates -- with reference to duplicates in a specific column (called 'colName'):
count before dedupe:
df.count()
do the de-dupe (convert the column you are de-duping to string type):
from pyspark.sql.functions import col
df = df.withColumn('colName',col('colName').cast('string'))
df.drop_duplicates(subset=['colName']).count()
can use a sorted groupby to check to see that duplicates have been removed:
df.groupBy('colName').count().toPandas().set_index("count").sort_index(ascending=False)
sudo apt-get install php-mbstring
# if your are using php 7.1
sudo apt-get install php7.1-mbstring
# if your are using php 7.2
sudo apt-get install php7.2-mbstring
I got it to work by doing this, assuming you are using PDO.
//Place query here, let's say you want all the users that have blue as their favorite color
$sql = "SELECT name FROM user WHERE favorite_color = :color";
//set parameters
//you may set as many parameters as you have on your query
$params['color'] = blue;
//create the prepared statement, by getting the doctrine connection
$stmt = $this->entityManager->getConnection()->prepare($sql);
$stmt->execute($params);
//I used FETCH_COLUMN because I only needed one Column.
return $stmt->fetchAll(PDO::FETCH_COLUMN);
You can change the FETCH_TYPE to suit your needs.
In case of your jdk version less than 1.5, following option can be used.
int iTest = 2;
StringBuffer sTest = new StringBuffer("000000"); //if the string size is 6
sTest.append(String.valueOf(iTest));
System.out.println(sTest.substring(sTest.length()-6, sTest.length()));
Correct way to check for null or empty or string containing only spaces is like this:
if(str != null && !str.trim().isEmpty()) { /* do your stuffs here */ }
No, I don't know one.
If you want to retain the original directory for some reason (ACLs, &c.), and instead really want to empty it, then you can do the following:
del /q destination\*
for /d %x in (destination\*) do @rd /s /q "%x"
This first removes all files from the directory, and then recursively removes all nested directories, but overall keeping the top-level directory as it is (except for its contents).
Note that within a batch file you need to double the %
within the for
loop:
del /q destination\*
for /d %%x in (destination\*) do @rd /s /q "%%x"
Edit 2018-05-28 I have changed the example to use Java 8's Time API:
LocalDate d1 = LocalDate.parse("2018-05-26", DateTimeFormatter.ISO_LOCAL_DATE);
LocalDate d2 = LocalDate.parse("2018-05-28", DateTimeFormatter.ISO_LOCAL_DATE);
Duration diff = Duration.between(d1.atStartOfDay(), d2.atStartOfDay());
long diffDays = diff.toDays();
Always, always, always put disposable objects inside of using statements. I can't see how you've instantiated your DataReader but you should do it like this:
using (Connection c = ...)
{
using (DataReader dr = ...)
{
//Work with dr in here.
}
}
//Now the connection and reader have been closed and disposed.
Now, to answer your question, the reader is using the same connection as the command you're trying to ExecuteNonQuery
on. You need to use a separate connection since the DataReader keeps the connection open and reads data as you need it.
Here is another, in my opinion even simpler solution using a flex wrapper:
HTML:
<div class="wrapper">
<p>Text</p>
<div class="line"></div>
</div>
CSS:
.wrapper {
display: flex;
align-items: center;
}
.line {
border-top: 1px solid grey;
flex-grow: 1;
margin: 0 10px;
}
To do this for any object in JavaScript will not be simple or straightforward. You will run into the problem of erroneously picking up attributes from the object's prototype that should be left in the prototype and not copied to the new instance. If, for instance, you are adding a clone
method to Object.prototype
, as some answers depict, you will need to explicitly skip that attribute. But what if there are other additional methods added to Object.prototype
, or other intermediate prototypes, that you don't know about? In that case, you will copy attributes you shouldn't, so you need to detect unforeseen, non-local attributes with the hasOwnProperty
method.
In addition to non-enumerable attributes, you'll encounter a tougher problem when you try to copy objects that have hidden properties. For example, prototype
is a hidden property of a function. Also, an object's prototype is referenced with the attribute __proto__
, which is also hidden, and will not be copied by a for/in loop iterating over the source object's attributes. I think __proto__
might be specific to Firefox's JavaScript interpreter and it may be something different in other browsers, but you get the picture. Not everything is enumerable. You can copy a hidden attribute if you know its name, but I don't know of any way to discover it automatically.
Yet another snag in the quest for an elegant solution is the problem of setting up the prototype inheritance correctly. If your source object's prototype is Object
, then simply creating a new general object with {}
will work, but if the source's prototype is some descendant of Object
, then you are going to be missing the additional members from that prototype which you skipped using the hasOwnProperty
filter, or which were in the prototype, but weren't enumerable in the first place. One solution might be to call the source object's constructor
property to get the initial copy object and then copy over the attributes, but then you still will not get non-enumerable attributes. For example, a Date
object stores its data as a hidden member:
function clone(obj) {
if (null == obj || "object" != typeof obj) return obj;
var copy = obj.constructor();
for (var attr in obj) {
if (obj.hasOwnProperty(attr)) copy[attr] = obj[attr];
}
return copy;
}
var d1 = new Date();
/* Executes function after 5 seconds. */
setTimeout(function(){
var d2 = clone(d1);
alert("d1 = " + d1.toString() + "\nd2 = " + d2.toString());
}, 5000);
The date string for d1
will be 5 seconds behind that of d2
. A way to make one Date
the same as another is by calling the setTime
method, but that is specific to the Date
class. I don't think there is a bullet-proof general solution to this problem, though I would be happy to be wrong!
When I had to implement general deep copying I ended up compromising by assuming that I would only need to copy a plain Object
, Array
, Date
, String
, Number
, or Boolean
. The last 3 types are immutable, so I could perform a shallow copy and not worry about it changing. I further assumed that any elements contained in Object
or Array
would also be one of the 6 simple types in that list. This can be accomplished with code like the following:
function clone(obj) {
var copy;
// Handle the 3 simple types, and null or undefined
if (null == obj || "object" != typeof obj) return obj;
// Handle Date
if (obj instanceof Date) {
copy = new Date();
copy.setTime(obj.getTime());
return copy;
}
// Handle Array
if (obj instanceof Array) {
copy = [];
for (var i = 0, len = obj.length; i < len; i++) {
copy[i] = clone(obj[i]);
}
return copy;
}
// Handle Object
if (obj instanceof Object) {
copy = {};
for (var attr in obj) {
if (obj.hasOwnProperty(attr)) copy[attr] = clone(obj[attr]);
}
return copy;
}
throw new Error("Unable to copy obj! Its type isn't supported.");
}
The above function will work adequately for the 6 simple types I mentioned, as long as the data in the objects and arrays form a tree structure. That is, there isn't more than one reference to the same data in the object. For example:
// This would be cloneable:
var tree = {
"left" : { "left" : null, "right" : null, "data" : 3 },
"right" : null,
"data" : 8
};
// This would kind-of work, but you would get 2 copies of the
// inner node instead of 2 references to the same copy
var directedAcylicGraph = {
"left" : { "left" : null, "right" : null, "data" : 3 },
"data" : 8
};
directedAcyclicGraph["right"] = directedAcyclicGraph["left"];
// Cloning this would cause a stack overflow due to infinite recursion:
var cyclicGraph = {
"left" : { "left" : null, "right" : null, "data" : 3 },
"data" : 8
};
cyclicGraph["right"] = cyclicGraph;
It will not be able to handle any JavaScript object, but it may be sufficient for many purposes as long as you don't assume that it will just work for anything you throw at it.
You can use apache commons IO..
FileInputStream fisTargetFile = new FileInputStream(new File("test.txt"));
String targetFileStr = IOUtils.toString(fisTargetFile, "UTF-8");

The error tells you EXACTLY what the problem is (and running in the debugger or reading the stack trace will tell you exactly where the problem is):
C# Collection was modified; enumeration operation may not execute.
Your problem is the loop
foreach (KeyValuePair<int, int> kvp in rankings) {
//
}
wherein you modify the collection rankings
. In particular, the offensive line is
rankings[kvp.Key] = rankings[kvp.Key] + 4;
Before you enter the loop, add the following line:
var listOfRankingsToModify = new List<int>();
Replace the offending line with
listOfRankingsToModify.Add(kvp.Key);
and after you exit the loop
foreach(var key in listOfRankingsToModify) {
rankings[key] = rankings[key] + 4;
}
That is, record what changes you need to make, and make them without iterating over the collection that you need to modify.

The simple way, to actually merge specific files from two branches, not just replace specific files with ones from another branch.
git diff branch_b > my_patch_file.patch
Creates a patch file of the difference between the current branch and branch_b
git apply -p1 --include=pattern/matching/the/path/to/file/or/folder my_patch_file.patch
You can use *
as a wildcard in the include pattern.
Slashes don't need to be escaped.
Also, you could use --exclude instead and apply it to everything except the files matching the pattern, or reverse the patch with -R
The -p1 option is a holdover from the *Unix patch command and the fact that the patch file's contents prepend each file name with a/
or b/
(or more depending on how the patch file was generated) which you need to strip, so that it can figure out the real file to the path to the file the patch needs to be applied to.
Check out the man page for git-apply for more options.
Obviously you'd want to commit your changes, but who's to say you don't have some other related tweaks you want to do before making your commit.
Get Screen Width and Height in terms of DP with some good decoration:
Step 1: Create interface
public interface ScreenInterface {
float getWidth();
float getHeight();
}
Step 2: Create implementer class
public class Screen implements ScreenInterface {
private Activity activity;
public Screen(Activity activity) {
this.activity = activity;
}
private DisplayMetrics getScreenDimension(Activity activity) {
DisplayMetrics displayMetrics = new DisplayMetrics();
activity.getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
return displayMetrics;
}
private float getScreenDensity(Activity activity) {
return activity.getResources().getDisplayMetrics().density;
}
@Override
public float getWidth() {
DisplayMetrics displayMetrics = getScreenDimension(activity);
return displayMetrics.widthPixels / getScreenDensity(activity);
}
@Override
public float getHeight() {
DisplayMetrics displayMetrics = getScreenDimension(activity);
return displayMetrics.heightPixels / getScreenDensity(activity);
}
}
Step 3: Get width and height in activity:
Screen screen = new Screen(this); // Setting Screen
screen.getWidth();
screen.getHeight();
The best way to do that programmatically is using the next method:
public static DigitsKeyListener getInstance (boolean sign, boolean decimal)
Returns a DigitsKeyListener that accepts the digits 0 through 9, plus the minus sign (only at the beginning) and/or decimal point (only one per field) if specified.
This solve the problem about the many '.' in EditText
editText.setKeyListener(DigitsKeyListener.getInstance(true,true)); // decimals and positive/negative numbers.
editText.setKeyListener(DigitsKeyListener.getInstance(false,true)); // positive decimals numbers.
editText.setKeyListener(DigitsKeyListener.getInstance(false,false)); // positive integer numbers.
editText.setKeyListener(DigitsKeyListener.getInstance(true,false)); // positive/negative integer numbers.
I've found my optimal blocksize to be 8 MB (equal to disk cache?) I needed to wipe (some say: wash) the empty space on a disk before creating a compressed image of it. I used:
cd /media/DiskToWash/
dd if=/dev/zero of=zero bs=8M; rm zero
I experimented with values from 4K to 100M.
After letting dd to run for a while I killed it (Ctlr+C) and read the output:
36+0 records in
36+0 records out
301989888 bytes (302 MB) copied, 15.8341 s, 19.1 MB/s
As dd displays the input/output rate (19.1MB/s in this case) it's easy to see if the value you've picked is performing better than the previous one or worse.
My scores:
bs= I/O rate
---------------
4K 13.5 MB/s
64K 18.3 MB/s
8M 19.1 MB/s <--- winner!
10M 19.0 MB/s
20M 18.6 MB/s
100M 18.6 MB/s
Note: To check what your disk cache/buffer size is, you can use sudo hdparm -i /dev/sda
Because the act of acquiring the position and getting the element from the given position naturally requires some locking (you can't have the list have structural changes between those two operations).
The very idea of a concurrent collection is that each operation on its own is atomic and can be done without explicit locking/synchronization.
Therefore getting the element at position n
from a given List
as an atomic operation doesn't make too much sense in a situation where concurrent access is anticipated.
I think I have come up with a quite shorter solution.. Hope it helps someone.
cbind.na<-function(df1, df2){

#Get absent rownames for both of the dataframe
absent.names.1<-setdiff(x = rownames(df1),y = rownames(df))
absent.names.2<-setdiff(x = rownames(df2),y = rownames(df))
#Fill absents with NAs
df1.fixed<-data.frame(row.names = absent.names.1,matrix(data = NA,nrow = length(absent.names.1),ncol=ncol(df1)))

df2.fixed<-data.frame(row.names = absent.names.2,matrix(data = NA,nrow = length(absent.names.2),ncol=ncol(df2)))
colnames(df2.fixed)<-colnames(df2)

#Finally cbind into new dataframe
df<-cbind(df,df1[rownames(df),],df2[rownames(df),])

The import form and the module declaration need to agree about the shape of the module, about what it exports.
When you write (a suboptimal practice for importing JSON since TypeScript 2.9 when targeting compatible module formatssee note)
declare module "*.json" {
const value: any;
export default value;
}
You are stating that all modules that have a specifier ending in .json
have a single export named default
.
There are several ways you can correctly consume such a module including
import a from "a.json";
a.primaryMain
and
import * as a from "a.json";
a.default.primaryMain
and
import {default as a} from "a.json";
a.primaryMain
and
import a = require("a.json");
a.default.primaryMain
The first form is the best and the syntactic sugar it leverages is the very reason JavaScript has default
exports.
However I mentioned the other forms to give you a hint about what's going wrong. Pay special attention to the last one. require
gives you an object representing the module itself and not its exported bindings.
So why the error? Because you wrote
import a = require("a.json");
a.primaryMain
And yet there is no export named primaryMain
declared by your "*.json"
.
All of this assumes that your module loader is providing the JSON as the default
export as suggested by your original declaration.
Note: Since TypeScript 2.9, you can use the --resolveJsonModule
compiler flag to have TypeScript analyze imported .json
files and provide correct information regarding their shape obviating the need for a wildcard module declaration and validating the presence of the file. This is not supported for certain target module formats.
These are more compact and versatile forms of Hamish's answer. They handle any mixture of upper and lower case letters:
read -r -p "Are you sure? [y/N] " response
case "$response" in
[yY][eE][sS]|[yY])
do_something
;;
*)
do_something_else
;;
esac
Or, for Bash >= version 3.2:
read -r -p "Are you sure? [y/N] " response
if [[ "$response" =~ ^([yY][eE][sS]|[yY])$ ]]
then
do_something
else
do_something_else
fi
Note: If $response
is an empty string, it will give an error. To fix, simply add quotation marks: "$response"
. – Always use double quotes in variables containing strings (e.g.: prefer to use "$@"
instead $@
).
Or, Bash 4.x:
read -r -p "Are you sure? [y/N] " response
response=${response,,} # tolower
if [[ "$response" =~ ^(yes|y)$ ]]
...
Edit:
In response to your edit, here's how you'd create and use a confirm
command based on the first version in my answer (it would work similarly with the other two):
confirm() {
# call with a prompt string or use a default
read -r -p "${1:-Are you sure? [y/N]} " response
case "$response" in
[yY][eE][sS]|[yY])
true
;;
*)
false
;;
esac
}
To use this function:
confirm && hg push ssh://..
or
confirm "Would you really like to do a push?" && hg push ssh://..
Here is how to apply CSS code directly without using <link>
to load an extra stylesheet.
var head = jQuery("#iframe").contents().find("head");
var css = '<style type="text/css">' +
'#banner{display:none}; ' +
'</style>';
jQuery(head).append(css);
This hides the banner in the iframe page. Thank you for your suggestions!
This can be done using the numeric_limits in C++:
http://www.cplusplus.com/reference/limits/numeric_limits/
These are the methods you probably want to look at:
infinity() T Representation of positive infinity, if available.
quiet_NaN() T Representation of quiet (non-signaling) "Not-a-Number", if available.
signaling_NaN() T Representation of signaling "Not-a-Number", if available.
Just add them:
['it'] + ['was'] + ['annoying']

@Test
public void testFoo() {
TestObject testObj = new TestObject(mockFoo);
assertEquals(0, testObj.bar());
assertEquals(1, testObj.bar());
assertEquals(-1, testObj.bar());
assertEquals(-1, testObj.bar());
}
private void setupFoo() {
mockFoo = mock(Foo.class);
when(mockFoo.someMethod())
.thenReturn(0)
.thenReturn(1)
.thenReturn(-1); //any subsequent call will return -1
// Or a bit shorter with varargs:
when(mockFoo.someMethod())
.thenReturn(0, 1, -1); //any subsequent call will return -1
}
}
The only way I think then to get the functionality you want would be to do something like
import junit.framework.Test;
import junit.framework.TestResult;
import junit.framework.TestSuite;
public class AllTests {
public static Test suite() {
TestSuite suite = new TestSuite("TestEverything");
//$JUnit-BEGIN$
suite.addTestSuite(TestOne.class);
suite.addTestSuite(TestTwo.class);
suite.addTestSuite(TestThree.class);
//$JUnit-END$
}
public static void main(String[] args)
{
AllTests test = new AllTests();
Test testCase = test.suite();
TestResult result = new TestResult();
setUp();
testCase.run(result);
tearDown();
}
public void setUp() {}
public void tearDown() {}
}
I use something like this in eclipse, so I'm not sure how portable it is outside of that environment
The CompileSdkVersion
is the version of the SDK platform your app works with for compilation, etc DURING the development process (you should always use the latest) This is shipped with the API version you are using
You will see this in your build.gradle
file:
targetSdkVersion:
contains the info your app ships with AFTER the development process to the app store that allows it to TARGET the SPECIFIED version of the Android platform
. Depending on the functionality of your app, it can target API versions lower than the current.For instance, you can target API 18 even if the current version is 23.
Take a good look at this official Google page.
from s in context.shift
where !context.employeeshift.Any(es=>(es.shiftid==s.shiftid)&&(es.empid==57))

you can't change the DateTime object, it's immutable. However, you can set it to a new value, for example:
var newDate = oldDate.Date + new TimeSpan(11, 30, 55);
Try a system like this instead:
.container {_x000D_
width: 80%;_x000D_
height: 200px;_x000D_
background: aqua;_x000D_
margin: auto;_x000D_
padding: 10px;_x000D_
}_x000D_
_x000D_
.one {_x000D_
width: 15%;_x000D_
height: 200px;_x000D_
background: red;_x000D_
float: left;_x000D_
}_x000D_
_x000D_
.two {_x000D_
margin-left: 15%;_x000D_
height: 200px;_x000D_
background: black;_x000D_
}
_x000D_
<section class="container">_x000D_
<div class="one"></div>_x000D_
<div class="two"></div>_x000D_
</section>
_x000D_
You only need to float one div if you use margin-left on the other equal to the first div's width. This will work no matter what the zoom and will not have sub-pixel problems.
This answer is easy to understand

How does the virtual keyword work?
Assume that Man is a base class, Indian is derived from man.
Class Man
{
public:
virtual void do_work()
{}
}
Class Indian : public Man
{
public:
void do_work()
{}
}
Declaring do_work() as virtual simply means: which do_work() to call will be determined ONLY at run-time.
Suppose I do,
Man *man;
man = new Indian();
man->do_work(); // Indian's do work is only called.
If virtual is not used, the same is statically determined or statically bound by the compiler, depending on what object is calling. So if an object of Man calls do_work(), Man's do_work() is called EVEN THOUGH IT POINTS TO AN INDIAN OBJECT
I believe that the top voted answer is misleading - Any method whether or not virtual can have an overridden implementation in the derived class. With specific reference to C++ the correct difference is run-time (when virtual is used) binding and compile-time (when virtual is not used but a method is overridden and a base pointer is pointed at a derived object) binding of associated functions.
There seems to be another misleading comment that says,
"Justin, 'pure virtual' is just a term (not a keyword, see my answer below) used to mean "this function cannot be implemented by the base class."
THIS IS WRONG! Purely virtual functions can also have a body AND CAN BE IMPLEMENTED! The truth is that an abstract class' pure virtual function can be called statically! Two very good authors are Bjarne Stroustrup and Stan Lippman.... because they wrote the language.
A simple solution would be to configure static http headers needed for all calls in the bean configuration of the RestTemplate:
@Configuration
public class RestTemplateConfig {
@Bean
public RestTemplate getRestTemplate(@Value("${did-service.bearer-token}") String bearerToken) {
RestTemplate restTemplate = new RestTemplate();
restTemplate.getInterceptors().add((request, body, clientHttpRequestExecution) -> {
HttpHeaders headers = request.getHeaders();
if (!headers.containsKey("Authorization")) {
String token = bearerToken.toLowerCase().startsWith("bearer") ? bearerToken : "Bearer " + bearerToken;
request.getHeaders().add("Authorization", token);
}
return clientHttpRequestExecution.execute(request, body);
});
return restTemplate;
}
}
I'm afraid that the first of those command lines unconditionally deleted from the working copy all the files that are in git's staging area. The second one unstaged all the files that were tracked but have now been deleted. Unfortunately this means that you will have lost any uncommitted modifications to those files.
If you want to get your working copy and index back to how they were at the last commit, you can (carefully) use the following command:
git reset --hard
I say "carefully" since git reset --hard
will obliterate uncommitted changes in your working copy and index. However, in this situation it sounds as if you just want to go back to the state at your last commit, and the uncommitted changes have been lost anyway.
Update: it sounds from your comments on Amber's answer that you haven't yet created any commits (since HEAD cannot be resolved), so this won't help, I'm afraid.
As for how those pipes work: git ls-files -z
and git diff --name-only --diff-filter=D -z
both output a list of file names separated with the byte 0
. (This is useful, since, unlike newlines, 0
bytes are guaranteed not to occur in filenames on Unix-like systems.) The program xargs
essentially builds command lines from its standard input, by default by taking lines from standard input and adding them to the end of the command line. The -0
option says to expect standard input to by separated by 0
bytes. xargs
may invoke the command several times to use up all the parameters from standard input, making sure that the command line never becomes too long.
As a simple example, if you have a file called test.txt
, with the following contents:
hello
goodbye
hello again
... then the command xargs echo whatever < test.txt
will invoke the command:
echo whatever hello goodbye hello again
I'm using laravel 7.x and this problem arose.. the following fixed it:
go to kernel.php and add these 2 classes to protected $middleware
\Illuminate\Session\Middleware\StartSession::class, \Illuminate\View\Middleware\ShareErrorsFromSession::class,
When you make the input, set it to be readonly.
<input type="text" name="datepicker" id="datepicker" readonly="readonly" />
This happened to me when I ^C
in the middle of a git push
to GitHub. GitHub did not show that the changes had been made, however.
To fix it, I made a change to my working tree, committed, and then pushed again. It worked perfectly fine.
Pickle serializes a single object at a time, and reads back a single object - the pickled data is recorded in sequence on the file.
If you simply do pickle.load
you should be reading the first object serialized into the file (not the last one as you've written).
After unserializing the first object, the file-pointer is at the beggining
of the next object - if you simply call pickle.load
again, it will read that next object - do that until the end of the file.
objects = []
with (open("myfile", "rb")) as openfile:
while True:
try:
objects.append(pickle.load(openfile))
except EOFError:

In addition to the answer already accepted, for the scenario when you want to define a default property as a function of other properties you can use expression body notation on C#6.0 (and higher) for even more elegant and concise constructs like:
public class Person{
public string FullName => $"{First} {Last}"; // expression body notation
public string First { get; set; } = "First";
public string Last { get; set; } = "Last";
}
You can use the above in the following fashion
var p = new Person();
p.FullName; // First Last
p.First = "Jon";
p.Last = "Snow";
p.FullName; // Jon Snow
In order to be able to use the above "=>" notation, the property must be read only, and you do not use the get accessor keyword.

You could use the Firefox add-on User Agent Overrider. With this add-on you can use whatever user agent you want, for examlpe:
Firefox 28/Android: Mozilla/5.0 (Android; Mobile; rv:28.0) Gecko/24.0 Firefox/28.0
If your website detects mobile devices through the user agent then you can test your layout this way.
Update Nov '17:
Due to the release of Firefox 57 and the introduction of web extension this add-on sadly is no longer available. Alternatively you can edit the Firefox preference general.useragent.override
in your configuration:

Here is a proper explanation of "still reachable":
"Still reachable" are leaks assigned to global and static-local variables. Because valgrind tracks global and static variables it can exclude memory allocations that are assigned "once-and-forget". A global variable assigned an allocation once and never reassigned that allocation is typically not a "leak" in the sense that it does not grow indefinitely. It is still a leak in the strict sense, but can usually be ignored unless you are pedantic.
Local variables that are assigned allocations and not free'd are almost always leaks.
Here is an example
int foo(void)
{
static char *working_buf = NULL;
char *temp_buf;
if (!working_buf) {
working_buf = (char *) malloc(16 * 1024);
}
temp_buf = (char *) malloc(5 * 1024);
....
....
....
}
Valgrind will report working_buf as "still reachable - 16k" and temp_buf as "definitely lost - 5k".
As already pointed out on this answer, KeyValuePair<TKey, TValue>
implements a Deconstruct
method starting on .NET Core 2.0, .NET Standard 2.1 and .NET Framework 5.0 (preview).
With this, it's possible to iterate through a dictionary in a KeyValuePair
agnostic way:
var dictionary = new Dictionary<int, string>();
// ...
foreach (var (key, value) in dictionary)
{
// ...
}
var connect = require('connect');
var serveStatic = require('serve-static');
var app = connect();
app.use(serveStatic('../angularjs'), {default: 'angular.min.js'}); app.listen(3000);

Use the INTERVAL
type to it. E.g:
--yesterday
SELECT NOW() - INTERVAL '1 DAY';
--Unrelated to the question, but PostgreSQL also supports some shortcuts:
SELECT 'yesterday'::TIMESTAMP, 'tomorrow'::TIMESTAMP, 'allballs'::TIME;
Then you can do the following on your query:
SELECT
org_id,
count(accounts) AS COUNT,
((date_at) - INTERVAL '1 DAY') AS dateat
FROM
sourcetable
WHERE
date_at <= now() - INTERVAL '130 DAYS'
GROUP BY
org_id,
dateat;
You can append multiple operands. E.g.: how to get last day of current month?
SELECT date_trunc('MONTH', CURRENT_DATE) + INTERVAL '1 MONTH - 1 DAY';
You can also create an interval using make_interval
function, useful when you need to create it at runtime (not using literals):
SELECT make_interval(days => 10 + 2);
SELECT make_interval(days => 1, hours => 2);
SELECT make_interval(0, 1, 0, 5, 0, 0, 0.0);
Generate random number between 0 to 99:
int x = arc4random()%100;
Generate random number between 500 and 1000:
int x = (arc4random()%501) + 500;
Try using another temporary pair:
pair<string,double> temp;
vector<pair<string,double>> revenue;
// Inside the loop
temp.first = "string";
temp.second = map[i].second;
revenue.push_back(temp);
You can use GROUP_CONCAT to perform that, e.g. something like
SELECT p.id, p.name, GROUP_CONCAT(s.name) AS site_list
FROM sites s
INNER JOIN publications p ON(s.id = p.site_id)
GROUP BY p.id, p.name;
The modern approach is to move away from VBA for important code, and write a .NET managed Add-In using c# or vb.net, there are a lot of resources for this on the www, and you could use the Express version of MS Visual Studio
Personally:
for _ in range(50):
print "Some thing"
if you don't need i
. If you use Python < 3 and you want to repeat the loop a lot of times, use xrange
as there is no need to generate the whole list beforehand.
As has been suggested at least twice, you can use descendingIterator
with a Deque
, in particular with a LinkedList
. If you want to use the for-each loop (i.e., have an Iterable
), you can construct and use a wraper like this:
import java.util.*;
public class Main {
public static class ReverseIterating<T> implements Iterable<T> {
private final LinkedList<T> list;
public ReverseIterating(LinkedList<T> list) {
this.list = list;
}
@Override
public Iterator<T> iterator() {
return list.descendingIterator();
}
}
public static void main(String... args) {
LinkedList<String> list = new LinkedList<String>();
list.add("A");
list.add("B");
list.add("C");
list.add("D");
list.add("E");
for (String s : new ReverseIterating<String>(list)) {
System.out.println(s);
}
}
}
One of the most efficient ways to replace matching strings (without regular expressions) is to use the Aho-Corasick algorithm with a performant Trie (pronounced "try"), fast hashing algorithm, and efficient collections implementation.
A simple solution leverages Apache's StringUtils.replaceEach
as follows:
private String testStringUtils(
final String text, final Map<String, String> definitions ) {
final String[] keys = keys( definitions );
final String[] values = values( definitions );
return StringUtils.replaceEach( text, keys, values );
}
This slows down on large texts.
Bor's implementation of the Aho-Corasick algorithm introduces a bit more complexity that becomes an implementation detail by using a façade with the same method signature:
private String testBorAhoCorasick(
final String text, final Map<String, String> definitions ) {
// Create a buffer sufficiently large that re-allocations are minimized.
final StringBuilder sb = new StringBuilder( text.length() << 1 );
final TrieBuilder builder = Trie.builder();
builder.onlyWholeWords();
builder.removeOverlaps();
final String[] keys = keys( definitions );
for( final String key : keys ) {
builder.addKeyword( key );
}
final Trie trie = builder.build();
final Collection<Emit> emits = trie.parseText( text );
int prevIndex = 0;
for( final Emit emit : emits ) {
final int matchIndex = emit.getStart();
sb.append( text.substring( prevIndex, matchIndex ) );
sb.append( definitions.get( emit.getKeyword() ) );
prevIndex = emit.getEnd() + 1;
}
// Add the remainder of the string (contains no more matches).
sb.append( text.substring( prevIndex ) );
return sb.toString();
}
For the benchmarks, the buffer was created using randomNumeric as follows:
private final static int TEXT_SIZE = 1000;
private final static int MATCHES_DIVISOR = 10;
private final static StringBuilder SOURCE
= new StringBuilder( randomNumeric( TEXT_SIZE ) );
Where MATCHES_DIVISOR
dictates the number of variables to inject:
private void injectVariables( final Map<String, String> definitions ) {
for( int i = (SOURCE.length() / MATCHES_DIVISOR) + 1; i > 0; i-- ) {
final int r = current().nextInt( 1, SOURCE.length() );
SOURCE.insert( r, randomKey( definitions ) );
}
}
The benchmark code itself (JMH seemed overkill):
long duration = System.nanoTime();
final String result = testBorAhoCorasick( text, definitions );
duration = System.nanoTime() - duration;
System.out.println( elapsed( duration ) );
A simple micro-benchmark with 1,000,000 characters and 1,000 randomly-placed strings to replace.
No contest.
Using 10,000 characters and 1,000 matching strings to replace:
The divide closes.
Using 1,000 characters and 10 matching strings to replace:
For short strings, the overhead of setting up Aho-Corasick eclipses the brute-force approach by StringUtils.replaceEach
.
A hybrid approach based on text length is possible, to get the best of both implementations.
Consider comparing other implementations for text longer than 1 MB, including:

I'm using Debian 7 64-bit.
I didn't have a .vimrc file in my home folder. I created one and was able to set user defaults for vim.
However, for Debian 7, another way is to edit /etc/vim/vimrc
Here is a comment block in that file:
" All system-wide defaults are set in $VIMRUNTIME/debian.vim (usually just
" /usr/share/vim/vimcurrent/debian.vim) and sourced by the call to :runtime
" you can find below. If you wish to change any of those settings, you should
" do it in this file (/etc/vim/vimrc), since debian.vim will be overwritten
" everytime an upgrade of the vim packages is performed. It is recommended to
" make changes after sourcing debian.vim since it alters the value of the
" 'compatible' option.
I prefer
if(ddl.Items.FindByValue(string) != null)
{
ddl.Items.FindByValue(string).Selected = true;
}
Replace ddl with the dropdownlist ID and string with your string variable name or value.
I believe my input is controlled since it has a value.
For an input to be controlled, its value must correspond to that of a state variable.
That condition is not initially met in your example because this.state.name
is not initially set. Therefore, the input is initially uncontrolled. Once the onChange
handler is triggered for the first time, this.state.name
gets set. At that point, the above condition is satisfied and the input is considered to be controlled. This transition from uncontrolled to controlled produces the error seen above.
By initializing this.state.name
in the constructor:
e.g.
this.state = { name: '' };
the input will be controlled from the start, fixing the issue. See React Controlled Components for more examples.
Unrelated to this error, you should only have one default export. Your code above has two.
Circular dependency is also one of the reasons for this. [in general]
I was getting this error after adding the include files and linking the library. It was because the lib was built with non-unicode and my application was unicode. Matching them fixed it.
Unfortunately my proximity sensor doesn't work, too (always returns 0.0 cm). I found the way, but not easy one: you need to root your phone, install XPOSED framework and Sensor Disabler (https://play.google.com/store/apps/details?id=com.mrchandler.disableprox). You can mock proximity sensor return value in the app. (e.g. always return 2.0 cm). Then your display will be always on during the call.
Using the java.time

An alternative is to use StreamReader.
public void FunctionName(HttpPostedFileBase file)
{
string result = new StreamReader(file.InputStream).ReadToEnd();
}
Use following code,I have tested it and its working
var prev_val;
$('.dropdown').focus(function() {
prev_val = $(this).val();
}).change(function(){
$(this).unbind('focus');
var conf = confirm('Are you sure want to change status ?');
if(conf == true){
//your code
}
else{
$(this).val(prev_val);
$(this).bind('focus');
return false;
}
});
Not very elegant solution, but "works":
a
{
color: #fff;
}
a:hover
{
text-shadow: -1px 0 #fff, 0 1px #fff, 1px 0 #fff, 0 -1px #fff;
}
If you want another way:
"ayy
:
This will store the line in buffer a
.
"ap

There are many variations on this.
"a5yy

In our case, we receive an XML as a String
and need to get rid of the values that have some "special" characters, like &<>
etc. Basically someone can provide an XML to us in this form:
<notes>
<note>
<to>jenice & carl </to>
<from>your neighbor <; </from>
</note>
</notes>
So I need to find in that String
the values jenice & carl
and your neighbor <;
and properly escape &
and <
(otherwise this is an invalid xml if you later pass it to an engine that shall rename unnamed).
Doing this with regex is a rather dumb idea to begin with, but it's cheap and easy. So the brave ones that would like to do the same thing I did, here you go:
String xml = ...
Pattern p = Pattern.compile("<(.+)>(?!\\R<)(.+)</(\\1)>");
Matcher m = p.matcher(xml);
String result = m.replaceAll(mr -> {
if (mr.group(2).contains("&")) {
return "<" + m.group(1) + ">" + m.group(2) + "+ some change" + "</" + m.group(3) + ">";
}
return "<" + m.group(1) + ">" + mr.group(2) + "</" + m.group(3) + ">";
});
Not executing a corresponding SELECT query before running the DELETE query (particularly on production databases)!

You can save it as .txt and change it manually using a mouse click and your keyboard. OR, when saving the file:
All types(*.*)
in the Save as type
field.File name
fieldFrom the documentation:
__file__
is the pathname of the file from which the module was loaded, if it was loaded from a file. The__file__
attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.
From the mailing list thread linked by @kindall in a comment to the question:
I haven't tried to repro this particular example, but the reason is that we don't want to have to call getpwd() on every import nor do we want to have some kind of in-process variable to cache the current directory. (getpwd() is relatively slow and can sometimes fail outright, and trying to cache it has a certain risk of being wrong.)
What we do instead, is code in site.py that walks over the elements of sys.path and turns them into absolute paths. However this code runs before '' is inserted in the front of sys.path, so that the initial value of sys.path is ''.
For the rest of this, consider sys.path
not to include ''
.
So, if you are outside the part of sys.path
that contains the module, you'll get an absolute path. If you are inside the part of sys.path
that contains the module, you'll get a relative path.
If you load a module in the current directory, and the current directory isn't in sys.path
, you'll get an absolute path.
If you load a module in the current directory, and the current directory is in sys.path
, you'll get a relative path.
If you're looking to paginate results, use the integrated paginator, it works great!
$games = Game::paginate(30);

I don't know if this is the correct way however I did this:
<div class="control-group">
<label class="control-label" for="id1">Label:</label>
<div class="controls">
<textarea id="id1" class="textareawidth" rows="10" name="anyname">value</textarea>
</div>
</div>
and put this in my bootstrapcustom.css file:
@media (min-width: 768px) {
.textareawidth {
width:500px;
}
}
@media (max-width: 767px) {
.textareawidth {
}
}
This way it resizes based on the viewport. Seems to line everything up nicely on a big browser and on a small mobile device.
This is happening be cause you have 2 classes with same name. For, example, I have 2 SOAP web-services named settings and settings2 both have the same class GetEmployee and this is ambiguous proving the error.
I had something similar, and here's (an edited) version of what I ended up using successfully:
ISNULL(CONVERT(VARCHAR(50),[column name goes here],[date style goes here] ),'')
Here's why this works: If you select a date which is NULL, it will show return NULL, though it is really stored as 01/01/1900. This is why an ISNULL on the date field, while you're working with any date data type will not treat this as a NULL, as it is technically not being stored as a NULL.
However, once you convert it to a new datatype, it will convert it as a NULL, and at that point, you're ISNULL will work as you expect it to work.
I hope this works out for you as well!
~Eli
Update, nearly one year later:
I had a similar situation, where I needed the output to be of the date data-type, and my aforementioned solution didn't work (it only works if you need it displayed as a date, not be of the date data type.
If you need it to be of the date data-type, there is a way around it, and this is to nest a REPLACE
within an ISNULL
, the following worked for me:
Select
ISNULL(
REPLACE(
[DATE COLUMN NAME],
'1900-01-01',
''
),
'') AS [MeaningfulAlias]
Very old question, but for the newcomers: maybe the PowerShell version (similar but not equivalent) that the question is looking for, is to use -and

(build_command) -and (run_tests_command)
It's difficult to get the last field using cut, but here are some solutions in awk and perl
echo 1:2:3:4:5 | awk -F: '{print $NF}'
echo 1:2:3:4:5 | perl -F: -wane 'print $F[-1]'
All of the other answers are correct. However, if the thing you want to alloc using alloca()
is reasonably small, I think that it's a good technique that's faster and more convenient than using malloc()
or otherwise.
In other words, alloca( 0x00ffffff )
is dangerous and likely to cause overflow, exactly as much as char hugeArray[ 0x00ffffff ];
is. Be cautious and reasonable and you'll be fine.
Here's another fix that works for me:
(event.target as HTMLInputElement).value
That should get rid of the error by letting TS know that event.target
is an HTMLInputElement
, which inherently has a value
. Before specifying, TS likely only knew that event
alone was an HTMLInputElement
, thus according to TS the keyed-in target
was some randomly mapped value that could be anything.
TestClass.instance_methods
or without all the inherited methods
TestClass.instance_methods - Object.methods
(Was 'TestClass.methods - Object.methods')
I found a faster way of embedding:
It is true that if you present a view controller modally on the iPhone, it will always be presented full screen no matter how you present it on the top view controller of a navigation controller or any other way around. But you can always show the navigation bar with the following workaround way:
Rather than presenting that view controller modally present a navigation controller modally with its root view controller set as the view controller you want:
MyViewController *myViewController = [[MyViewController alloc] initWithNibName:nil bundle:nil];
UINavigationController *navigationController =
[[UINavigationController alloc] initWithRootViewController:myViewController];
//now present this navigation controller modally
[self presentViewController:navigationController
animated:YES
completion:^{
}];
You should see a navigation bar when your view is presented modally.
You should add the g
modifier so that sed performs a global substitution of the contents of the pattern buffer:
echo dog dog dos | sed -e 's:dog:log:g'
For a fantastic documentation on sed, check http://www.grymoire.com/Unix/Sed.html. This global flag is explained here: http://www.grymoire.com/Unix/Sed.html#uh-6
The official documentation for GNU sed
is available at http://www.gnu.org/software/sed/manual/
Thanks to everyone for responding so fast. Joel, I used your option 2 and added a registry key to the "Run" folder of the current user. Here's the code I used for anyone else who's interested.
using Microsoft.Win32;
private void SetStartup()
{
RegistryKey rk = Registry.CurrentUser.OpenSubKey
("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true);
if (chkStartUp.Checked)
rk.SetValue(AppName, Application.ExecutablePath);
else
rk.DeleteValue(AppName,false);
}
players
is a list which needs to be indexed by integers. You seem to be using it like a dictionary. Maybe you could use unpacking -- Something like:
name, score = player
(if the player
list is always a constant length).
There's not much more advice we can give you without knowing what query
is and how it works.
It's worth pointing out that the entire code you posted doesn't make a whole lot of sense. There's an IndentationError
on the second line. Also, your function is looping over some iterable, but unconditionally returning during the first iteration which isn't usually what you actually want to do.
or you can use package doBy
library(doBy)
dd <- orderBy(~-z+b, data=dd)
This might work for you:
sed 's|$ROOT|'"${HOME}"'|g' abc.sh > abc.sh.1
This code will work for Swift 4.2.
let controller:SecondViewController =
self.storyboard!.instantiateViewController(withIdentifier: "secondViewController") as!
SecondViewController
controller.view.frame = self.view.bounds;
self.view.addSubview(controller.view)
self.addChild(controller)
controller.didMove(toParent: self)
You can try this:
SELECT DATE(DATE_ADD(m_inv_reqdate, INTERVAL + 1 DAY)) FROM tr08_investment
If You try to connect by pysftp to "normal" FTP You have to set hostkey to None.
import pysftp
cnopts = pysftp.CnOpts()
cnopts.hostkeys = None
with pysftp.Connection(host='****',username='****',password='***',port=22,cnopts=cnopts) as sftp:
print('DO SOMETHING')
