i agree with you about alternative solutions which you mentioned above
1. Use POST instead of GET;
2. Transform the List into a JSON string and pass it to the service.
and its true that you can't add List
to MultiValuedMap
because of its impl class MultivaluedMapImpl
have capability to accept String Key and String Value. which is shown in following figure
still you want to do that things than try following code.
Controller Class
package net.yogesh.test;
import java.util.List;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import com.google.gson.Gson;
@Path("test")
public class TestController {
@Path("testMethod")
@GET
@Produces("application/text")
public String save(
@QueryParam("list") List<String> list) {
return new Gson().toJson(list) ;
}
}
Client Class
package net.yogesh.test;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import javax.ws.rs.core.MultivaluedMap;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
import com.sun.jersey.api.client.config.ClientConfig;
import com.sun.jersey.api.client.config.DefaultClientConfig;
import com.sun.jersey.core.util.MultivaluedMapImpl;
public class Client {
public static void main(String[] args) {
String op = doGet("http://localhost:8080/JerseyTest/rest/test/testMethod");
System.out.println(op);
}
private static String doGet(String url){
List<String> list = new ArrayList<String>();
list = Arrays.asList(new String[]{"string1,string2,string3"});
MultivaluedMap<String, String> params = new MultivaluedMapImpl();
String lst = (list.toString()).substring(1, list.toString().length()-1);
params.add("list", lst);
ClientConfig config = new DefaultClientConfig();
com.sun.jersey.api.client.Client client = com.sun.jersey.api.client.Client.create(config);
WebResource resource = client.resource(url);
ClientResponse response = resource.queryParams(params).type("application/x-www-form-urlencoded").get(ClientResponse.class);
String en = response.getEntity(String.class);
return en;
}
}
hope this'll help you.
You can use Pillow (Website, Documentation, GitHub, PyPI). Pillow has the same interface as PIL, but works with Python 3.
$ pip install Pillow
If you don't have administrator rights (sudo on Debian), you can use
$ pip install --user Pillow
Other notes regarding the installation are here.
from PIL import Image
with Image.open(filepath) as img:
width, height = img.size
This needed 3.21 seconds for 30336 images (JPGs from 31x21 to 424x428, training data from National Data Science Bowl on Kaggle)
This is probably the most important reason to use Pillow instead of something self-written. And you should use Pillow instead of PIL (python-imaging), because it works with Python 3.
I keep scipy.ndimage.imread
as the information is still out there, but keep in mind:
imread is deprecated! imread is deprecated in SciPy 1.0.0, and [was] removed in 1.2.0.
import scipy.ndimage
height, width, channels = scipy.ndimage.imread(filepath).shape
import pygame
img = pygame.image.load(filepath)
width = img.get_width()
height = img.get_height()
APScheduler might be what you are after.
from datetime import date
from apscheduler.scheduler import Scheduler
# Start the scheduler
sched = Scheduler()
sched.start()
# Define the function that is to be executed
def my_job(text):
print text
# The job will be executed on November 6th, 2009
exec_date = date(2009, 11, 6)
# Store the job in a variable in case we want to cancel it
job = sched.add_date_job(my_job, exec_date, ['text'])
# The job will be executed on November 6th, 2009 at 16:30:05
job = sched.add_date_job(my_job, datetime(2009, 11, 6, 16, 30, 5), ['text'])
https://apscheduler.readthedocs.io/en/latest/
You can just get it to schedule another run by building that into the function you are scheduling.
Best option would be
Add a compare validator to the web form. Set its controlToValidate. Set its Type property to Date. Set its operator property to DataTypeCheck eg:
<asp:CompareValidator
id="dateValidator" runat="server"
Type="Date"
Operator="DataTypeCheck"
ControlToValidate="txtDatecompleted"
ErrorMessage="Please enter a valid date.">
</asp:CompareValidator>
I'm interpreting your question to be about getting row numbers.
as.numeric(rownames(df))
if you haven't set the rownames. Otherwise use a sequence of 1:nrow(df)
. which()
function converts a TRUE/FALSE row index into row numbers. Maybe you'll find this on Google while trying to write a regex that is able to match segments of a line (as opposed to entire lines) which do not contain a substring. Tooke me a while to figure out, so I'll share:
Given a string:
<span class="good">bar</span><span class="bad">foo</span><span class="ugly">baz</span>
I want to match <span>
tags which do not contain the substring "bad".
/<span(?:(?!bad).)*?>
will match <span class=\"good\">
and <span class=\"ugly\">
.
Notice that there are two sets (layers) of parentheses:
Demo in Ruby:
s = '<span class="good">bar</span><span class="bad">foo</span><span class="ugly">baz</span>'
s.scan(/<span(?:(?!bad).)*?>/)
# => ["<span class=\"good\">", "<span class=\"ugly\">"]
It seems nobody found a solution for this. I don't have one based on only css neither but by using this JavaScript trick I usually can handle disabled input fields.
Remember that disabled fields always follow the style that they got before becoming disabled. So the trick would be 1- Enabling them 2-Change the class 3- Disable them again. Since this happens very fast user cannot understand what happened.
A simple JavaScript code would be something like:
function changeDisabledClass (id, disabledClass){
var myInput=document.getElementById(id);
myInput.disabled=false; //First make sure it is not disabled
myInput.className=disabledClass; //change the class
myInput.disabled=true; //Re-disable it
}
Take a look at this question and this question for some good answers on C++ object instantiation.
This basic idea is that objects instantiated on the heap (using new) need to be cleaned up manually, those instantiated on the stack (without new) are automatically cleaned up when they go out of scope.
void SomeFunc()
{
Point p1 = Point(0,0);
} // p1 is automatically freed
void SomeFunc2()
{
Point *p1 = new Point(0,0);
delete p1; // p1 is leaked unless it gets deleted
}
You can use the System.Diagnostics.Process.Start method to start a process. You can even pass a URL as a string and it'll kick off the default browser.
It tells taskkill
that the next parameter something.exe
is an image name, a.k.a executable name
C:\>taskkill /?
TASKKILL [/S system [/U username [/P [password]]]]

Allows "*" to be used. ex. imagename eq acme*
/PID processid Specifies the PID of the process to be terminated.
Use TaskList to get the PID.
/IM imagename Specifies the image name of the process
to be terminated. Wildcard '*' can be used
to specify all tasks or image names.
/T Terminates the specified process and any
child processes which were started by it.
/F Specifies to forcefully terminate the process(es).
/? Displays this help message.
As it's not specified if you mean the system's current date or the date held in a variable, I'll answer for latter with an example.
<?php
$dateAsString = "Wed, 11 Apr 2018 19:00:00 -0500";
// This converts it to a unix timestamp so that the date() function can work with it.
$dateAsUnixTimestamp = strtotime($dateAsString);
// Output it month is various formats according to http://php.net/date
echo date('M',$dateAsUnixTimestamp);
// Will output Apr
echo date('n',$dateAsUnixTimestamp);
// Will output 4
echo date('m',$dateAsUnixTimestamp);
// Will output 04
?>
You can find all of those operators in the Python language reference, though you'll have to scroll around a bit to find them all. As other answers have said:
**
operator does exponentiation. a ** b
is a
raised to the b
power. The same **
symbol is also used in function argument and calling notations, with a different meaning (passing and receiving arbitrary keyword arguments).^
operator does a binary xor. a ^ b
will return a value with only the bits set in a
or in b
but not both. This one is simple!%
operator is mostly to find the modulus of two integers. a % b
returns the remainder after dividing a
by b
. Unlike the modulus operators in some other programming languages (such as C), in Python a modulus it will have the same sign as b
, rather than the same sign as a
. The same operator is also used for the "old" style of string formatting, so a % b
can return a string if a
is a format string and b
is a value (or tuple of values) which can be inserted into a
.//
operator does Python's version of integer division. Python's integer division is not exactly the same as the integer division offered by some other languages (like C), since it rounds towards negative infinity, rather than towards zero. Together with the modulus operator, you can say that a == (a // b)*b + (a % b)
. In Python 2, floor division is the default behavior when you divide two integers (using the normal division operator /
). Since this can be unexpected (especially when you're not picky about what types of numbers you get as arguments to a function), Python 3 has changed to make "true" (floating point) division the norm for division that would be rounded off otherwise, and it will do "floor" division only when explicitly requested. (You can also get the new behavior in Python 2 by putting from __future__ import division
at the top of your files. I strongly recommend it!)There are a couple of things to be aware of:
src/main/resources/public
will be served from the root of your application.
For example src/main/resources/public/hello.jpg
would be served from http://localhost:8080/hello.jpg
This is why your current matcher configuration hasn't permitted access to the static resources. For /resources/**
to work, you would have to place the resources in src/main/resources/public/resources
and access them at http://localhost:8080/resources/your-resource
.
As you're using Spring Boot, you may want to consider using its defaults rather than adding extra configuration. Spring Boot will, by default, permit access to /css/**
, /js/**
, /images/**
, and /**/favicon.ico
. You could, for example, have a file named src/main/resources/public/images/hello.jpg
and, without adding any extra configuration, it would be accessible at http://localhost:8080/images/hello.jpg
without having to log in. You can see this in action in the web method security smoke test where access is permitted to the Bootstrap CSS file without any special configuration.
Try to use:
require('events').EventEmitter.defaultMaxListeners = Infinity;
Use the .Clear
method.
Sheets("Test").Range("A1:C3").Clear
Key insights for me were: - ensure that label content comes after the input-radio field - I tweaked my css to make everything a little closer
.radio-inline+.radio-inline {
margin-left: 5px;
}
This is because, even though Var1
exists, you're also using an assignment statement on the name Var1
inside of the function (Var1 -= 1
at the bottom line). Naturally, this creates a variable inside the function's scope called Var1
(truthfully, a -=
or +=
will only update (reassign) an existing variable, but for reasons unknown (likely consistency in this context), Python treats it as an assignment). The Python interpreter sees this at module load time and decides (correctly so) that the global scope's Var1
should not be used inside the local scope, which leads to a problem when you try to reference the variable before it is locally assigned.
Using global variables, outside of necessity, is usually frowned upon by Python developers, because it leads to confusing and problematic code. However, if you'd like to use them to accomplish what your code is implying, you can simply add:
global Var1, Var2
inside the top of your function. This will tell Python that you don't intend to define a Var1
or Var2
variable inside the function's local scope. The Python interpreter sees this at module load time and decides (correctly so) to look up any references to the aforementioned variables in the global scope.
nonlocal
statement - check that out as well.In our case git
had to be installed on the Jenkins server.
Just in case you want to find PID of the instance and kill the process, assuming that the node is listening to port 9300 (the default port) you can run the following command :
kill -9 $(netstat -nlpt | grep 9200 | cut -d ' ' -f 58 | cut -d '/' -f 1)
You may have to play with the numbers in the above-mentioned code such as 58 and 1
You can do in a very simple way. The idea is to place a Label in the same place as your textbox. Your Label will be visible if textbox has no text and hasn't the focus.
<Label Name="PalceHolder" HorizontalAlignment="Left" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Height="40" VerticalAlignment="Top" Width="239" FontStyle="Italic" Foreground="BurlyWood">PlaceHolder Text Here
<Label.Style>
<Style TargetType="{x:Type Label}">
<Setter Property="Visibility" Value="Hidden"/>
<Style.Triggers>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding ="{Binding ElementName=PalceHolder, Path=Text.Length}" Value="0"/>
<Condition Binding ="{Binding ElementName=PalceHolder, Path=IsFocused}" Value="False"/>
</MultiDataTrigger.Conditions>
<Setter Property="Visibility" Value="Visible"/>
</MultiDataTrigger>
</Style.Triggers>
</Style>
</Label.Style>
</Label>
<TextBox Background="Transparent" Name="TextBox1" HorizontalAlignment="Left" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Height="40"TextWrapping="Wrap" Text="{Binding InputText,Mode=TwoWay}" VerticalAlignment="Top" Width="239" />
Bonus:If you want to have default value for your textBox, be sure after to set it when submitting data (for example:"InputText"="PlaceHolder Text Here" if empty).
Just run below command with admin access
npm install --global --production windows-build-tools
In case you're already using the transform property for positioning your element (as I currently am), you can also animate the top margin:
.ball {
animation: bounce 1s infinite alternate;
-webkit-animation: bounce 1s infinite alternate;
}
@keyframes bounce {
from {
margin-top: 0;
}
to {
margin-top: -15px;
}
}
Neither of these options is correct. You're trying to implement a synchronous interface asynchronously. Don't do that. The problem is that when DoOperation()
returns, the operation won't be complete yet. Worse, if an exception happens during the operation (which is very common with IO operations), the user won't have a chance to deal with that exception.
What you need to do is to modify the interface, so that it is asynchronous:
interface IIO
{
Task DoOperationAsync(); // note: no async here
}
class IOImplementation : IIO
{
public async Task DoOperationAsync()
{
// perform the operation here
}
}
This way, the user will see that the operation is async
and they will be able to await
it. This also pretty much forces the users of your code to switch to async
, but that's unavoidable.
Also, I assume using StartNew()
in your implementation is just an example, you shouldn't need that to implement asynchronous IO. (And new Task()
is even worse, that won't even work, because you don't Start()
the Task
.)
You need to use method Array.filter
:
this.persons = this.personService.getPersons().filter(x => x.id == this.personId)[0];
or Array.find
this.persons = this.personService.getPersons().find(x => x.id == this.personId);

Please see this, more current solution before using a custom parsing function like below, or a 3rd party library.
The a code below works and is still useful in situations where URLSearchParams
is not available, but it was written in a time when there was no native solution available in JavaScript. In modern browsers or Node.js, prefer to use the built-in functionality.
function parseURLParams(url) {
var queryStart = url.indexOf("?") + 1,
queryEnd = url.indexOf("#") + 1 || url.length + 1,
query = url.slice(queryStart, queryEnd - 1),
pairs = query.replace(/\+/g, " ").split("&"),
parms = {}, i, n, v, nv;
if (query === url || query === "") return;
for (i = 0; i < pairs.length; i++) {
nv = pairs[i].split("=", 2);
n = decodeURIComponent(nv[0]);
v = decodeURIComponent(nv[1]);
if (!parms.hasOwnProperty(n)) parms[n] = [];
parms[n].push(nv.length === 2 ? v : null);
}
return parms;
}
Use as follows:
var urlString = "http://www.example.com/bar?a=a+a&b%20b=b&c=1&c=2&d#hash";
urlParams = parseURLParams(urlString);
which returns a an object like this:
{
"a" : ["a a"], /* param values are always returned as arrays */
"b b": ["b"], /* param names can have special chars as well */
"c" : ["1", "2"] /* an URL param can occur multiple times! */
"d" : [null] /* parameters without values are set to null */
}
So
parseURLParams("www.mints.com?name=something")
gives
{name: ["something"]}
EDIT: The original version of this answer used a regex-based approach to URL-parsing. It used a shorter function, but the approach was flawed and I replaced it with a proper parser.
Another very simple way to parse ISO8601 timestamps is to use org.apache.commons.lang.time.DateUtils
:
import static org.junit.Assert.assertEquals;
import java.text.ParseException;
import java.util.Date;
import org.apache.commons.lang.time.DateUtils;
import org.junit.Test;
public class ISO8601TimestampFormatTest {
@Test
public void parse() throws ParseException {
Date date = DateUtils.parseDate("2010-01-01T12:00:00+01:00", new String[]{ "yyyy-MM-dd'T'HH:mm:ssZZ" });
assertEquals("Fri Jan 01 12:00:00 CET 2010", date.toString());
}
}
I've created my own formatting utility. Which is extremely fast at processing the formatting along with giving you many features :)
It supports:
The code can be found here. You call it like this:
public static void main(String[])
{
int settings = ValueFormat.COMMAS | ValueFormat.PRECISION(2) | ValueFormat.MILLIONS;
String formatted = ValueFormat.format(1234567, settings);
}
I should also point out this doesn't handle decimal support, but is very useful for integer values. The above example would show "1.23M" as the output. I could probably add decimal support maybe, but didn't see too much use for it since then I might as well merge this into a BigInteger type of class that handles compressed char[] arrays for math computations.
function setValToAssessment(id)
{
$.getJSON("<?= URL.$param->module."/".$param->controller?>/setvalue",{id: id}, function(response)
{
var form = $('<form></form>').attr("id",'hiddenForm' ).attr("name", 'hiddenForm');
$.each(response,function(key,value){
$("<input type='text' value='"+value+"' >")
.attr("id", key)
.attr("name", key)
.appendTo("form");
});
$('#hiddenForm').appendTo('body').submit();
// window.location.href = "<?=URL.$param->module?>/assessment";
});
}
My solution to this problem is:
document.onkeypress = function (event) {
event = (event || window.event);
if (event.keyCode == 123) {
return false;
}
}
With the magic number 123
which is the key F12.

I still think that Harry's answer is the simplest and completed but if you need something even simpler, then use:
struct AppError {
let message: String
init(message: String) {
self.message = message
}
}
extension AppError: LocalizedError {
var errorDescription: String? { return message }
// var failureReason: String? { get }
// var recoverySuggestion: String? { get }
// var helpAnchor: String? { get }
}
And use or test it like this:
printError(error: AppError(message: "My App Error!!!"))
func print(error: Error) {
print("We have an ERROR: ", error.localizedDescription)
}
You can use expand.grid( ) function.
x <-c(1,2,3)
y <-c(100,200,300)
expand.grid(cond=x,rating=y)
I was experiencing a kind of similar issue:
System setup and Problem: (On a virtualbox I'm web hosting using ubuntu and nginx - PHP webpage refreshes did not reflect changes to external css file). I'm developing website on windows machine and transferring files to nginx via shared folder. It seems nginx does not pick up changes to css file (refreshing in any fashion does not help. Changing css file name is only thing that worked)
Solution: On VM find shared file (css file in my case). Open with nano and compare to file in windows share (they appear identical). On VM save shared file with nano. All changes are now reflected in browser. Not sure why this works but it did in my case.
UPDATE: After rebooting the VM server the problem returned. Following the instructions under Solution made the css responsive to updates again
There are two things here, and the highest voted answer is technically correct as per the OPs question.
Briefly summarized as:
$("some sort of selector").prop("disabled", true | false);
However should you be using jQuery UI (I know the OP wasn't but some people arriving here might be) then while this will disable the buttons click event it wont make the button appear disabled as per the UI styling.
If you are using a jQuery UI styled button then it should be enabled / disabled via:
$("some sort of selector").button("enable" | "disable");
<object Margin="left,top,right,bottom"/>

Truly, the question stated above is an programming issue. How would you like to program your code? Where do you need the 'STR' to be accessed? There is no use of declaring a variable which is used locally as a global variable. Basics of programming I believe.
Here's an idea using Object.defineProperty
which directly modifies the way a property is accessed.
Code:
function bind(base, el, varname) {
Object.defineProperty(base, varname, {
get: () => {
return el.value;
},
set: (value) => {
el.value = value;
}
})
}
Usage:
var p = new some_class();
bind(p,document.getElementById("someID"),'variable');
p.variable="yes"

OR conditions can be generated like this:
$collection->addFieldToFilter(
array('field_1', 'field_2', 'field_3'), // columns
array( // conditions
array( // conditions for field_1
array('in' => array('text_1', 'text_2', 'text_3')),
array('like' => '%text')
),
array('eq' => 'exact'), // condition for field 2
array('in' => array('val_1', 'val_2')) // condition for field 3
)
);
This will generate an SQL WHERE condition something like:
... WHERE (
(field_1 IN ('text_1', 'text_2', 'text_3') OR field_1 LIKE '%text')
OR (field_2 = 'exact')
OR (field_3 IN ('val_1', 'val_2'))
)
Each nested array(<condition>) generates another set of parentheses for an OR condition.
I have the same problem today, stuck on the kb2999226 for over an hour. First, i thought it is because i am using a VM on my local machine. But decided to cancel the installation, then install kb2999226 first, then install the vs2015 community again, it works out much better, the installation move forward and progressing. thx.
The other answers have covered the direct question well, but you may also be interested in using set -e
. With that, any command that fails (outside of specific contexts like if
tests) will cause the script to abort. For certain scripts, it's very useful.
Using the java.time
framework built into Java 8 and later.
import java.time.LocalDate;
import java.time.ZoneId;
int year = 2011;
int month = 10;
int day = 1;
int date = LocalDate.of(year, month, day);
date.atStartOfDay(ZoneId.of("UTC")).toEpochSecond; # Long = 1317427200
You can iterate through the array or you can convert it to a String
and use indexOf
.
if (new String(charArray).indexOf('q') < 0) {
break;
}
Creating a new String
is a bit wasteful, but it's probably the tersest code. You can also write a method to imitate the effect without incurring the overhead.

You don't need to install Entity Framework in your Console application, you just need to add a reference to the assembly EntityFramework.SqlServer.dll. You can copy this assembly from the Class Library project that uses Entity Framework to a LIB folder and add a reference to it.
In summary:
I hope it helps.
I authored the G2 project, a friendly environment for the command line git lover.
Please get the project from github - G2 https://github.com/orefalo/g2
It has a bunch of handy commands, one of them being exactly what your are looking for: freeze
freeze - Freeze all files in the repository (additions, deletions, modifications) to the staging area, thus staging that content for inclusion in the next commit. Also accept a specific path as parameter
Add a key, value pair to dictionary
aDict = {}
aDict[key] = value
What do you mean by dynamic addition.
You are binding the click
event to anchors with an href attribute with value sign_new
.
Either bind anchors with class sign_new
or bind anchors with href value #sign_up
. I would prefer the former.
There are many ways to achieve this but the easiest way in Python 3.6+, in my opinion, is this:
print(f"{1:03}")
Perhaps you can use JavaScript to solve your cross-browser problem. It uses a different escape mechanism, one with which you're obviously already familiar:
(reference-to-the-tag).title = "Some \"text\"";
It doesn't strictly separate the functions of HTML, JavaScript, and CSS the way folks want you to nowadays, but whom do you need to make happy? Your users or techies you don't know?
C# represents a character in UTF-16 coding rather than ASCII. Therefore converting a integer to character do not make any difference for A-Z and a-z. But I was working with ASCII Codes besides alphabets and number which did not work for me as system uses UTF-16 code. Therefore I browsed UTF-16 code for all UTF-16 character. Here is the module :
void utfchars()
{
int i, a, b, x;
ConsoleKeyInfo z;
do
{
a = 0; b = 0; Console.Clear();
for (i = 1; i <= 10000; i++)
{
if (b == 20)
{
b = 0;
a = a + 1;
}
Console.SetCursorPosition((a * 15) + 1, b + 1);
Console.Write("{0} == {1}", i, (char)i);
b = b+1;
if (i % 100 == 0)
{
Console.Write("\n\t\t\tPress any key to continue {0}", b);
a = 0; b = 0;
Console.ReadKey(true); Console.Clear();
}
}
Console.Write("\n\n\n\n\n\n\n\t\t\tPress any key to Repeat and E to exit");
z = Console.ReadKey();
if (z.KeyChar == 'e' || z.KeyChar == 'E') Environment.Exit(0);
} while (1 == 1);
}
Since android doesnt support <ol>, <ul> or <li>
html elements, I had to do it like this
<string name="names"><![CDATA[<p><h2>List of Names:</h2></p><p>•name1<br />•name2<br /></p>]]></string>
if you want to maintain custom space then use </pre> tag
Simply define a function and set the value of your Combobox to empty/null or whatever you want. Try the following.
def Reset():
cmb.set("")
here, cmb
is a variable in which you have assigned the Combobox. Now call that function in a button such as,
btn2 = ttk.Button(root, text="Reset",command=Reset)
yes,the sorting proceed differently. in first scenario, orders based on column1 and in addition to that process further by sorting colmun2 based on column1 .. in second scenario ,it orders completely based on column 1 only... please proceed with a simple example...u will get quickly..
First of all, don't use char*
or char[N]
. Use std::string
, then everything else becomes so easy!
Examples,
std::string s = "Hello";
std::string greet = s + " World"; //concatenation easy!
Easy, isn't it?
Now if you need char const *
for some reason, such as when you want to pass to some function, then you can do this:
some_c_api(s.c_str(), s.size());
assuming this function is declared as:
some_c_api(char const *input, size_t length);
Explore std::string
yourself starting from here:
Hope that helps.
It's a matter of operator precedence.
||
has a higher precedence than or
.
So, in between the two you have other operators including ternary (? :
) and assignment (=
) so which one you choose can affect the outcome of statements.
Here's a ruby operator precedence table.
See this question for another example using and
/&&
.
Also, be aware of some nasty things that could happen:
a = false || true #=> true
a #=> true
a = false or true #=> true
a #=> false
Both of the previous two statements evaluate to true
, but the second sets a
to false
since =
precedence is lower than ||
but higher than or
.
A compiler independent way, but not processor independent way to get these:
int inf = 0x7F800000;
return *(float*)&inf;
int nan = 0x7F800001;
return *(float*)&nan;
This should work on any processor which uses the IEEE 754 floating point format (which x86 does).
UPDATE: Tested and updated.
Yes, basically what you done is right, except you forget that JavaScript is sync in many cases, so you running the code before your DOM gets loaded, there are few ways to solve this:
1) Check to see if DOM fully loaded, then do whatever you want, you can listen to DOMContentLoaded for example:
<script>
document.addEventListener("DOMContentLoaded", function(event) {
console.log("DOM fully loaded and parsed");
});
</script>
2) Very common way is adding the script tag to the bottom of your document
(after body tag):
<html>
<head>
</head>
<body>
</body>
<script src="/bundle.js"></script>
</html>
3) Using window.onload
, which gets fired when the entire page loaded(img, etc)
window.addEventListener("load", function() {
console.log("Everything is loaded");
});
4) Using document.onload
, which gets fired when the DOM is ready:
document.addEventListener("load", function() {
console.log("DOM is ready");
});
There are even more options to check if DOM is ready, but the short answer is DO NOT run any script before you make sure your DOM is ready in every cases...
JavaScript is working along with DOM elements and if they are not available, will return null, could break the whole application... so always make sure you are fully ready to run your JavaScript before you do...
The CAST() function does not support the "official" data type "INT" in MySQL, it's not in the list of supported types. With MySQL, "SIGNED" (or "UNSIGNED") could be used instead:
CAST(columnName AS SIGNED)
However, this seems to be MySQL-specific (not standardized), so it may not work with other databases. At least this document (Second Informal Review Draft) ISO/IEC 9075:1992, Database does not list "SIGNED"/"UNSIGNED" in section 4.4 Numbers
.
But DECIMAL is both standardized and supported by MySQL, so the following should work for MySQL (tested) and other databases:
CAST(columnName AS DECIMAL(0))
According to the MySQL docs:
If the scale is 0, DECIMAL values contain no decimal point or fractional part.
Try
string fileName = "test.txt";
FileInfo f = new FileInfo(fileName);
string fullname = f.FullName;
See the official documentation reference: https://docs.docker.com/engine/reference/builder/#expose
The EXPOSE
allow you to define private (container) and public (host) ports to expose at image build time for when the container is running if you run the container with -P
.
$ docker help run
...
-P, --publish-all Publish all exposed ports to random ports
...
The public port and protocol are optional, if not a public port is specified, a random port will be selected on host by docker to expose the specified container port on Dockerfile.
A good pratice is do not specify public port, because it limits only one container per host ( a second container will throw a port already in use ).
You can use -p
in docker run
to control what public port the exposed container ports will be connectable.
Anyway, If you do not use EXPOSE
(with -P
on docker run) nor -p
, no ports will be exposed.
If you always use -p
at docker run
you do not need EXPOSE
but if you use EXPOSE
your docker run
command may be more simple, EXPOSE
can be useful if you don't care what port will be expose on host, or if you are sure of only one container will be loaded.

From High Performance Android Apps book (page 157):
I'd implement this:
public static bool Retry(int maxRetries, Func<bool, bool> method)
{
while (maxRetries > 0)
{
if (method(maxRetries == 1))
{
return true;
}
maxRetries--;
}
return false;
}
I wouldn't use exceptions the way they're used in the other examples. It seems to me that if we're expecting the possibility that a method won't succeed, its failure isn't an exception. So the method I'm calling should return true if it succeeded, and false if it failed.
Why is it a Func<bool, bool>
and not just a Func<bool>
? So that if I want a method to be able to throw an exception on failure, I have a way of informing it that this is the last try.
So I might use it with code like:
Retry(5, delegate(bool lastIteration)
{
// do stuff
if (!succeeded && lastIteration)
{
throw new InvalidOperationException(...)
}
return succeeded;
});
or
if (!Retry(5, delegate(bool lastIteration)
{
// do stuff
return succeeded;
}))
{
Console.WriteLine("Well, that didn't work.");
}
If passing a parameter that the method doesn't use proves to be awkward, it's trivial to implement an overload of Retry
that just takes a Func<bool>
as well.
You want "rbind".
b$b <- NA
new <- rbind(a, b)
rbind requires the data frames to have the same columns.
The first line adds column b to data frame b.
Results
> a <- data.frame(a=c(0,1,2), b=c(3,4,5), c=c(6,7,8))
> a
a b c
1 0 3 6
2 1 4 7
3 2 5 8
> b <- data.frame(a=c(9,10,11), c=c(12,13,14))

You must just put the values into parentheses:
'%s in %s' % (unicode(self.author), unicode(self.publication))
Here, for the first %s
the unicode(self.author)
will be placed. And for the second %s
, the unicode(self.publication)
will be used.
Note: You should favor
string formatting
over the%
Notation. More info here
According to solution showed by @sid-sha you have to put everything in the viewDidAppear:
method, otherwise you will not get the didRotateFromInterfaceOrientation:
fired, so something like:
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
UIInterfaceOrientation interfaceOrientation = [[UIApplication sharedApplication] statusBarOrientation];
if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||
interfaceOrientation == UIInterfaceOrientationLandscapeRight) {
NSNumber *value = [NSNumber numberWithInt:interfaceOrientation];
[[UIDevice currentDevice] setValue:value forKey:@"orientation"];
}
}
An update if one is using Express 4.2 then the timeout middleware has been removed so need to manually add it with
npm install connect-timeout
and in the code it has to be (Edited as per comment, how to include it in the code)
var timeout = require('connect-timeout');
app.use(timeout('100s'));
For structuring an app, this is one of the best guides that I've found:
Note that the structure recommended by Google is different than what you'll find in a lot of seed projects, but for large apps it's a lot saner.
Google also has a style guide that makes sense to use only if you also use Closure.
...this answer is incomplete, but I hope that the limited information above will be helpful to someone.
try this it worked in my case
backgroundImage: `url("${Background}")`
DELETE FROM deadline where ID IN (
SELECT d.ID FROM `deadline` d LEFT JOIN `job` ON deadline.job_id = job.job_id WHERE `status` = 'szamlazva' OR `status` = 'szamlazhato' OR `status` = 'fizetve' OR `status` = 'szallitva' OR `status` = 'storno');
I am not sure if that kind of sub query works in MySQL, but try it. I am assuming you have an ID column in your deadline table.
Best solution:
function startsWith(str, word) {
return str.lastIndexOf(word, 0) === 0;
}
And here is endsWith if you need that too:
function endsWith(str, word) {
return str.indexOf(word, str.length - word.length) !== -1;
}
For those that prefer to prototype it into String:
String.prototype.startsWith || (String.prototype.startsWith = function(word) {
return this.lastIndexOf(word, 0) === 0;
});
String.prototype.endsWith || (String.prototype.endsWith = function(word) {
return this.indexOf(word, this.length - word.length) !== -1;
});
Usage:
"abc".startsWith("ab")
true
"c".ensdWith("c")
true
With method:
startsWith("aaa", "a")
true
startsWith("aaa", "ab")
false
startsWith("abc", "abc")
true
startsWith("abc", "c")
false
startsWith("abc", "a")
true
startsWith("abc", "ba")
false
startsWith("abc", "ab")
true
Children inherit opacity. It'd be weird and inconvenient if they didn't.
You can use a translucent PNG file for your background image, or use an RGBa (a for alpha) color for your background color.
Example, 50% faded black background:
<div style="background-color:rgba(0, 0, 0, 0.5);">_x000D_
<div>_x000D_
Text added._x000D_
</div>_x000D_
</div>
_x000D_
To start server locally paste the below code in package.json and run npm start in command line.
"scripts": {
"start": "http-server -c-1 -p 8081"
},
Now this may include more than you need (and may not even work for command line applications in a non-graphical environment, I don't know), but there is nw.js. It's Blink (i.e. Chromium/Webkit) + io.js (i.e. Node.js).
You can use node-webkit-builder to build native executable binaries for Linux, OS X and Windows.
If you want a GUI, that's a huge plus. You can build one with web technologies.
If you don't, specify "node-main"
in the package.json
(and probably "window": {"show": false}
although maybe it works to just have a node-main
and not a main
)
I haven't tried to use it in exactly this way, just throwing it out there as a possibility. I can say it's certainly not an ideal solution for non-graphical Node.js applications.
Alternative way to check would be:
if (!$('#myModal').is(':visible')) {
// if modal is not shown/visible then do something
}
We can easily find xor of two variables by the using:
def xor(a,b):
return a !=b
Example:
xor(True,False) >>> True
In my experience, to use wmic
in a script, you need to get the nested quoting right:
wmic product where "name = 'Windows Azure Authoring Tools - v2.3'" call uninstall /nointeractive
quoting both the query and the name. But wmic will only uninstall things installed via windows installer.
In your controller, render the new
action from your create action if validation fails, with an instance variable, @car
populated from the user input (i.e., the params
hash). Then, in your view, add a logic check (either an if block around the form
or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params
values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car
is set.
From the documentation page
To set the page type pass the value in constructor
jsPDF(orientation, unit, format)
Creates new jsPDF document objectinstance Parameters:
orientation One of "portrait" or "landscape" (or shortcuts "p" (Default), "l")
unit Measurement unit to be used when coordinates are specified. One of "pt" (points), "mm" (Default), "cm", "in"
format One of 'a3', 'a4' (Default),'a5' ,'letter' ,'legal'
To set font size
setFontSize(size)
Sets font size for upcoming text elements.
Parameters:
{Number} size Font size in points.
As of npm@5
, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid. If you want to make sure everything is consistent, use npm cache verify
instead. On the other hand, if you're debugging an issue with the installer, you can use npm install --cache /tmp/empty-cache
to use a temporary cache instead of nuking the actual one.
If you're sure you want to delete the entire cache, rerun:
npm cache clean --force

This answer is different from the prior answers because it avoids the needless and asymmetric use of the --push
option in the set-url
command of git remote. In this way, both URLs are symmetric in their configuration. For skeptics, the git config as shown by cat ./.git/config
looks different with versus without this option.
git clone [email protected]:myuser/myrepo.git
git remote set-url --add origin [email protected]:myuser/myrepo.git
push
:$ git remote -v
origin [email protected]:myuser/myrepo.git (fetch)
origin [email protected]:myuser/myrepo.git (push)
origin [email protected]:myuser/myrepo.git (push)
$ git config --local --get-regexp ^remote\..+\.url$
remote.origin.url [email protected]:myuser/myrepo.git
remote.origin.url [email protected]:myuser/myrepo.git
git push
To delete an added URL:
git remote set-url --delete origin [email protected]:myuser/myrepo.git
I have found that Furius ISO mount works best for me. I am using a Debian based distro Knoppix. I use this to Open system.img
files all the time.
Furius ISO mount: https://packages.debian.org/sid/otherosfs/furiusisomount
"When I want to mount userdata.img by mount -o loop userdata.img /mnt/userdata (the same as system.img), it tells me mount: you must specify the filesystem type so I try the mount -t ext2 -o loop userdata.img /mnt/userdata, it said mount: wrong fs type, bad option, bad superblock on...
So, how to get the file from the inside of userdata.img?"
To load .img
files you have to select loop and load the .img
Select loop
Next you select mount Select mount
Furius ISO mount handles all the other options loading the .img
file to your /home/dir.

Visifire supports wide range of 2D and 3D charts with zooming and panning functionality.

The more recent tidyverse
way is to use the mutate_at
function:
library(tidyverse)
library(magrittr)
set.seed(88)
data <- data.frame(matrix(sample(1:40), 4, 10, dimnames = list(1:4, LETTERS[1:10])))
cols <- c("A", "C", "D", "H")
data %<>% mutate_at(cols, funs(factor(.)))
str(data)
$ A: Factor w/ 4 levels "5","17","18",..: 2 1 4 3
$ B: int 36 35 2 26
$ C: Factor w/ 4 levels "22","31","32",..: 1 2 4 3
$ D: Factor w/ 4 levels "1","9","16","39": 3 4 1 2
$ E: int 3 14 30 38
$ F: int 27 15 28 37
$ G: int 19 11 6 21
$ H: Factor w/ 4 levels "7","12","20",..: 1 3 4 2
$ I: int 23 24 13 8
$ J: int 10 25 4 33
You can use this and it should be working --> You must use toList
before making the new list using select:
db.Products
.where(x=>x.CategoryID == categoryID).ToList()
.select(x=>new Product { Name = p.Name}).ToList();
You need not specify receiver. You can use adb instead.
adb shell am broadcast -a com.whereismywifeserver.intent.TEST
--es sms_body "test from adb"
For more arguments such as integer extras, see the documentation.
Compatible with: Xcode 6.0.1+
You can create an empty array by specifying the Element type of your array in the declaration.
For example:
// Shortened forms are preferred
var emptyDoubles: [Double] = []
// The full type name is also allowed
var emptyFloats: Array<Float> = Array()
Example from the apple developer page (Array):
Hope this helps anyone stumbling onto this page.
You can use the following commands to delete.
Use the "match all docs" query in a delete by query command:
'<delete><query>*:*</query></delete>
You must also commit after running the delete so, to empty the index, run the following two commands:
curl http://localhost:8983/solr/update --data '<delete><query>*:*</query></delete>' -H 'Content-type:text/xml; charset=utf-8'
curl http://localhost:8983/solr/update --data '<commit/>' -H 'Content-type:text/xml; charset=utf-8'
Another strategy would be to add two bookmarks in your browser:
http://localhost:8983/solr/update?stream.body=<delete><query>*:*</query></delete>
http://localhost:8983/solr/update?stream.body=<commit/>

Using http.createServer
is very low-level and really not useful for creating web applications as-is.
A good framework to use on top of it is Express, and I would seriously suggest using it. You can install it using npm install express
.
When you have, you can create a basic application to handle your form:
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
//Note that in version 4 of express, express.bodyParser() was
//deprecated in favor of a separate 'body-parser' module.
app.use(bodyParser.urlencoded({ extended: true }));
//app.use(express.bodyParser());
app.post('/myaction', function(req, res) {
res.send('You sent the name "' + req.body.name + '".');
});
app.listen(8080, function() {
console.log('Server running at http://127.0.0.1:8080/');
});
You can make your form point to it using:
<form action="http://127.0.0.1:8080/myaction" method="post">
The reason you can't run Node on port 80 is because there's already a process running on that port (which is serving your index.html
). You could use Express to also serve static content, like index.html
, using the express.static
middleware.
simply do the select
:
Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date) AND
((@day = 'Monday' AND (Monday = 1))
OR (@day = 'Tuesday' AND (Tuesday = 1))
OR (Wednesday = 1))
If you want to merge the filters (eg. CSV and Excel files), use this formula:
OpenFileDialog of = new OpenFileDialog();
of.Filter = "CSV files (*.csv)|*.csv|Excel Files|*.xls;*.xlsx";
Or if you want to see XML or PDF files in one time use this:
of.Filter = @" XML or PDF |*.xml;*.pdf";
The guy that did AForge did a fairly good job but it's not commercial quality. It's great to learn from but you can tell he was learning too so he has some pretty serious mistakes like assuming the size of an image instead of using the correct bits per pixel.
I'm not knocking the guy, I respect the heck out of him for learning all that and show us how to do it. I think he's a Ph.D now or at least he's about to be so he's really smart it's just not a commercially usable library.
The Math.Net library has its own weirdness when working with Fourier transforms and complex images/numbers. Like, if I'm not mistaken, it outputs the Fourier transform in human viewable format which is nice for humans if you want to look at a picture of the transform but it's not so good when you are expecting the data to be in a certain format (the normal format). I could be mistaken about that but I just remember there was some weirdness so I actually went to the original code they used for the Fourier stuff and it worked much better. (ExocortexDSP v1.2 http://www.exocortex.org/dsp/)
Math.net also had some other funkyness I didn't like when dealing with the data from the FFT, I can't remember what it was I just know it was much easier to get what I wanted out of the ExoCortex DSP library. I'm not a mathematician or engineer though; to those guys it might make perfect sense.
So! I use the FFT code yanked from ExoCortex, which Math.Net is based on, without anything else and it works great.
And finally, I know it's not C#, but I've started looking at using FFTW (http://www.fftw.org/). And this guy already made a C# wrapper so I was going to check it out but haven't actually used it yet. (http://www.sdss.jhu.edu/~tamas/bytes/fftwcsharp.html)
OH! I don't know if you are doing this for school or work but either way there is a GREAT free lecture series given by a Stanford professor on iTunes University.
https://podcasts.apple.com/us/podcast/the-fourier-transforms-and-its-applications/id384232849
just to add to the answers here, I was using the height as a function with two options either specify the height if it is less than the window height, or set it back to auto
var windowHeight = $(window).height();
$('div#someDiv').height(function(){
if ($(this).height() < windowHeight)
return windowHeight;
return 'auto';
});
I needed to center the content vertically if it was smaller than the window height or else let it scroll naturally so this is what I came up with
A const is a compile-time constant whereas readonly allows a value to be calculated at run-time and set in the constructor or field initializer. So, a 'const' is always constant but 'readonly' is read-only once it is assigned.
Eric Lippert of the C# team has more information on different types of immutability.
From MSDN:
"The CompareTo method was designed primarily for use in sorting or alphabetizing operations. It should not be used when the primary purpose of the method call is to determine whether two strings are equivalent. To determine whether two strings are equivalent, call the Equals method."
They suggest using .Equals
instead of .CompareTo
when looking solely for equality. I am not sure if there is a difference between .Equals
and ==
for the string
class. I will sometimes use .Equals
or Object.ReferenceEquals
instead of ==
for my own classes in case someone comes along at a later time and redefines the ==
operator for that class.
I was asked to build a java system that will have the ability to load new code while running
You might want to base your system on OSGi (or at least take a lot at it), which was made for exactly this situation.
Messing with classloaders is really tricky business, mostly because of how class visibility works, and you do not want to run into hard-to-debug problems later on. For example, Class.forName(), which is widely used in many libraries does not work too well on a fragmented classloader space.
Here is an even simpler solution using base graphics and alpha-blending (which does not work on all graphics devices):
set.seed(42)
p1 <- hist(rnorm(500,4)) # centered at 4
p2 <- hist(rnorm(500,6)) # centered at 6
plot( p1, col=rgb(0,0,1,1/4), xlim=c(0,10)) # first histogram
plot( p2, col=rgb(1,0,0,1/4), xlim=c(0,10), add=T) # second
The key is that the colours are semi-transparent.
Edit, more than two years later: As this just got an upvote, I figure I may as well add a visual of what the code produces as alpha-blending is so darn useful:
Abstraction
We use many abstractions in our day-to-day lives.Consider a car.Most of us have an abstract view of how a car works.We know how to interact with it to get it to do what we want it to do: we put in gas, turn a key, press some pedals, and so on. But we don't necessarily understand what is going on inside the car to make it move and we don't need to. Millions of us use cars everyday without understanding the details of how they work.Abstraction helps us get to school or work!
A program can be designed as a set of interacting abstractions. In Java, these abstractions are captured in classes. The creator of a class obviusly has to know its interface, just as the driver of a car can use the vehicle without knowing how the engine works.
Encapsulation
Consider a Banking system.Banking system have properties like account no,account type,balance ..etc. If someone is trying to change the balance of the account,attempt can be successful if there is no encapsulation. Therefore encapsulation allows class to have complete control over their properties.
From Java How to Program about abstract classes:
Because they’re used only as superclasses in inheritance hierarchies, we refer to them as abstract superclasses. These classes cannot be used to instantiate objects, because abstract classes are incomplete. Subclasses must declare the “missing pieces” to become “concrete” classes, from which you can instantiate objects. Otherwise, these subclasses, too, will be abstract.
To answer your question "What is the reason to use interfaces?":
An abstract class’s purpose is to provide an appropriate superclass from which other classes can inherit and thus share a common design.
As opposed to an interface:
An interface describes a set of methods that can be called on an object, but does not provide concrete implementations for all the methods... Once a class implements an interface, all objects of that class have an is-a relationship with the interface type, and all objects of the class are guaranteed to provide the functionality described by the interface. This is true of all subclasses of that class as well.
So, to answer your question "I was wondering when I should use interfaces", I think you should use interfaces when you want a full implementation and use abstract classes when you want partial pieces for your design (for reusability)
Better than all above is ever to use Standard C specification for struct initialization:
struct StructType structVar = {0};
Here are all bits zero (ever).
The lazy-init="default"
setting on a bean only refers to what is set by the default-lazy-init
attribute of the enclosing beans element. The implicit default value of default-lazy-init
is false
.
If there is no lazy-init
attribute specified on a bean, it's always eagerly instantiated.
Good to also check the other combinators in the family and to get back to what is this specific one.
ul li
ul > li
ul + ul
ul ~ ul
Example checklist:
ul li
- Looking inside - Selects all the li
elements placed (anywhere) inside the ul
; Descendant selectorul > li
- Looking inside - Selects only the direct li
elements of ul
; i.e. it will only select direct children li
of ul
; Child Selector or Child combinator selectorul + ul
- Looking outside - Selects the ul
immediately following the ul
; It is not looking inside, but looking outside for the immediately following element; Adjacent Sibling Selectorul ~ ul
- Looking outside - Selects all the ul
which follows the ul
doesn't matter where it is, but both ul
should be having the same parent; General Sibling SelectorThe one we are looking at here is General Sibling Selector
Numbers have higher precedence than strings so of course the +
operators want to convert your strings into numbers before adding.
You could do:
print 'There are ' + CONVERT(varchar(10),@Number) +
' alias combinations did not match a record'
or use the (rather limited) formatting facilities of RAISERROR
:
RAISERROR('There are %i alias combinations did not match a record',10,1,@Number)
WITH NOWAIT
The curly braces ({}) are used to import named bindings and the concept behind it is destructuring assignment
A simple demonstration of how import statement works with an example can be found in my own answer to a similar question at When do we use '{ }' in javascript imports?.
try this
df.rename(columns={ df.columns[1]: "your value" }, inplace = True)
Have a look at the below code snippet.
@RequestMapping(value="/Add/{type}")
public ModelAndView addForm(@PathVariable String type ){
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName("addContent");
modelAndView.addObject("typelist",contentPropertyDAO.getType() );
modelAndView.addObject("property",contentPropertyDAO.get(type,0) );
return modelAndView;
}
Hope it helps in constructing your code.
Windows 8 64bit runs both 32bit and 64bit applications. You want chromedriver 32bit for the 32bit version of chrome you're using.
The current release of chromedriver (v2.16) has been mentioned as running much smoother since it's older versions (there were a lot of issues before). This post mentions this and some of the slight differences between chromedriver and running the normal firefox driver:
http://seleniumsimplified.com/2015/07/recent-course-source-code-changes-for-webdriver-2-46-0/
What you mentioned about "doesn't call main method" is an odd remark. You may want to elaborate.
Use the xattr
command. You can inspect the extended attributes:
$ xattr s.7z
com.apple.metadata:kMDItemWhereFroms
com.apple.quarantine
and use the -d
option to delete one extended attribute:
$ xattr -d com.apple.quarantine s.7z
$ xattr s.7z
com.apple.metadata:kMDItemWhereFroms
you can also use the -c
option to remove all extended attributes:
$ xattr -c s.7z
$ xattr s.7z
xattr -h
will show you the command line options, and xattr has a man page.
The other thing this does is push the function invocation to the bottom of the stack, preventing a stack overflow if you are recursively calling a function. This has the effect of a while
loop but lets the JavaScript engine fire other asynchronous timers.
I have been using this solution since iOS 5 or so without any problems. I made a utility function that I call in my view controllers. You need to do it either in viewDidLoad or any point after that.
void updateBackButtonTextForViewController(UIViewController *viewController, NSString *text)
{
if(! viewController.navigationItem.backBarButtonItem)
{
viewController.navigationItem.backBarButtonItem =
[[UIBarButtonItem alloc] initWithTitle:text
style:UIBarButtonItemStylePlain
target:nil action:nil];
}
else
{
viewController.navigationItem.backBarButtonItem.title = text;
}
}
In some cases the navigation item may already exist, in other cases it needs to be created. This accounts for both of those cases without messing with the navigation item title. It allows you to remove the title by simply passing in @""
.
If you're willing to give up a hint of abstraction, then you could use a custom wrapper class which simply passes everything through to the PDO. Say, something like this: (Warning, code untested)
class SQLitePDOWrapper
{
private $pdo;
public function __construct( $dns, $uname = null, $pwd = null, $opts = null )
{
$this->pdo = new PDO( $dns, $unam, $pwd, $opts );
}
public function __call( $nm, $args )
{
$ret = call_user_func_array( array( $this->pdo, $nm ), $args );
if( $ret instanceof PDOStatement )
{
return new StatementWrapper( $this, $ret, $args[ 0 ] );
// I'm pretty sure args[ 0 ] will always be your query,
// even when binding
}
return $ret;
}
}
class StatementWrapper
{
private $pdo; private $stat; private $query;
public function __construct( PDO $pdo, PDOStatement $stat, $query )
{
$this->pdo = $pdo;
$this->stat = $stat;
this->query = $query;
}
public function rowCount()
{
if( strtolower( substr( $this->query, 0, 6 ) ) == 'select' )
{
// replace the select columns with a simple 'count(*)
$res = $this->pdo->query(
'SELECT COUNT(*)' .
substr( $this->query,
strpos( strtolower( $this->query ), 'from' ) )
)->fetch( PDO::FETCH_NUM );
return $res[ 0 ];
}
return $this->stat->rowCount();
}
public function __call( $nm, $args )
{
return call_user_func_array( array( $this->stat, $nm ), $args );
}
}
for me a pretty simple and fool proof way would be to simply make a method caller method like so:
public static object methodCaller(String methodName)
{
if(methodName.equals("getName"))
return className.getName();
}
then when you need to call the method simply put something like this
//calling a toString method is unnessary here, but i use it to have my programs to both rigid and self-explanitory
System.out.println(methodCaller(methodName).toString());
A bit late to the party but still - I prefer using numpy where:
import numpy as np
df['First Season'] = np.where(df['First Season'] > 1990, 1, df['First Season'])
I have the same problem and tried all the solutions posted here like :
sudo apt-get autoremove mysql-server
but unfortunately it doesn't work for me on ubuntu 16.04. To uninstall the right package you need to :
sudo apt-get remove mysql-
when you tried to autocomplete using tab
the command it will list the following package :
mysql-client mysql-client-core-5.7 mysql-server mysql-server-core-5.7 mysql-workbench mythes-en-us
mysql-client-5.7 mysql-common mysql-server-5.7 mysql-utilities mysql-workbench-data
obviously choose the mysql-server-core-5.7
so it would be :
sudo apt-get remove mysql-server-core-5.7
and now you can uninstall all mysql and reinstall again using these command from johnny's answer :
sudo apt-get remove --purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get install mysql-server mysql-client
Now I solved it and the Error is GONE.
Right now there is no view:clear command. For laravel 4 this can probably help you: https://gist.github.com/cjonstrup/8228165
Disabling caching can be done by skipping blade. View caching is done because blade compiling each time is a waste of time.
Like you I also faced many problems implementing OCR in Android, but after much Googling I found the solution, and it surely is the best example of OCR.
Let me explain using step-by-step guidance.
First, download the source code from https://github.com/rmtheis/tess-two.
Import all three projects. After importing you will get an error.
To solve the error you have to create a res
folder in the tess-two project
First, just create res folder in tess-two by tess-two->RightClick->new Folder->Name it "res"
After doing this in all three project the error should be gone.
Now download the source code from https://github.com/rmtheis/android-ocr, here you will get best example.
Now you just need to import it into your workspace, but first you have to download android-ndk from this site:
http://developer.android.com/tools/sdk/ndk/index.html i have windows 7 - 32 bit PC so I have download http://dl.google.com/android/ndk/android-ndk-r9-windows-x86.zip this file
Now extract it suppose I have extract it into E:\Software\android-ndk-r9 so I will set this path on Environment Variable
Right Click on MyComputer->Property->Advance-System-Settings->Advance->Environment Variable-> find PATH on second below Box and set like path like below picture
done it
Now open cmd and go to on D:\Android Workspace\tess-two like below
If you have successfully set up environment variable of NDK then just type ndk-build just like above picture than enter you will not get any kind of error and all file will be compiled successfully:
Now download other source code also from https://github.com/rmtheis/tess-two , and extract and import it and give it name OCRTest, like in my PC which is in D:\Android Workspace\OCRTest
Import test-two in this and run OCRTest and run it; you will get the best example of OCR.
function scrollToBottom() {
$("#mContainer").animate({ scrollTop: $("#mContainer")[0].scrollHeight }, 1000);
}
This is the solution work from me and you find, I'm sure
In the bash shell, surround arithmetic expressions with $(( ... ))
$ echo $(( 7 / 3 ))

Although I think you are limited to integers.
While the question has been answered in general, I've found myself that there's a case when even existing known_hosts entry doesn't help. This happens when an SSH server sends ECDSA fingerprint and as a result, you'll have an entry like this:
|1|+HASH=|HASH= ecdsa-sha2-nistp256 FINGERPRINT=
The problem is that JSch prefers SHA_RSA and while connecting it will try to compare SHA-RSA fingerprint, which will result with error about "unknown host".
To fix this simply run:
$ ssh-keyscan -H -t rsa example.org >> known_hosts
or complain to Jcraft about prefering SHA_RSA instead of using the local HostKeyAlgorithms setting, although they don't seem to be too eager to fix their bugs.
One is a column (aka Series), while the other is a DataFrame:
In [1]: df = pd.DataFrame([[1,2], [3,4]], columns=['a', 'b'])
In [2]: df
Out[2]:
a b
0 1 2
1 3 4
The column 'b' (aka Series):
In [3]: df['b']
Out[3]:
0 2
1 4
Name: b, dtype: int64
The subdataframe with columns (position) in [1]:
In [4]: df[[1]]
Out[4]:
b
0 2
1 4
Note: it's preferable (and less ambiguous) to specify whether you're talking about the column name e.g. ['b'] or the integer location, since sometimes you can have columns named as integers:
In [5]: df.iloc[:, [1]]
Out[5]:
b
0 2
1 4
In [6]: df.loc[:, ['b']]
Out[6]:
b
0 2
1 4
In [7]: df.loc[:, 'b']
Out[7]:
0 2
1 4
Name: b, dtype: int64
There is one more option to rename field:
Useful if you deal with third party classes, which you are not able to annotate, or you just do not want to pollute the class with Jackson specific annotations.
The Jackson documentation for Mixins is outdated, so this example can provide more clarity. In essence: you create mixin class which does the serialization in the way you want. Then register it to the ObjectMapper:
objectMapper.addMixIn(ThirdParty.class, MyMixIn.class);
This error could also happen if the generated build file path exceeds the windows max path length of 255 characters. Make sure your project path is not too long, use short names as well.
I also had this issue while developping on HTML5 in local. I had issues with images and getImageData function. Finally, I discovered one can launch chrome with the --allow-file-access-from-file command switch, that get rid of this protection security. The only thing is that it makes your browser less safe, and you can't have one chrome instance with the flag on and another without the flag.

You can download the 10.7 Lion JDK from http://connect.apple.com.
Sign in and click the java
section on the right.
The jdk is installed into a different location then previous. This will result in IDEs (such as Eclipse) being unable to locate source code and javadocs.
At the time of writing the JDK ended up here:
/Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home
Open up eclipse preferences and go to Java --> Installed JREs page
Rather than use the "JVM Contents (MacOS X Default) we will need to use the JDK location
At the time of writing Search is not aware of the new JDK location; we we will need to click on the Add button
From the Add JRE wizard choose "MacOS X VM" for the JRE Type
For the JRE Definition Page we need to fill in the following:
The other fields will now auto fill, with the default JRE name being "Home". You can quickly correct this to something more meaningful:
Finish the wizard and return to the Installed JREs page
Choose "System JDK" from the list
You can now develop normally with:

field of the Request is public. You may do this :

I was facing a similar difficulty and none of the solutions presented here were optimal for what I was working on. What I had was a series of functions to display content in a modal and I was trying to refactor it under a single object definition making the functions, methods of the class. The problem came in when I found one of the methods created some nav-buttons inside the modal themselves which used an onClick to one of the functions -- now an object of the class. I have considered (and am still considering) other methods to handle these nav buttons, but I was able to find the variable name for the class itself by sweeping the variables defined in the parent window. What I did was search for anything matching the 'instanceof' my class, and in case there might be more than one, I compared a specific property that was likely to be unique to each instance:
var myClass = function(varName)
{
this.instanceName = ((varName != null) && (typeof(varName) == 'string') && (varName != '')) ? varName : null;
/**
* caching autosweep of window to try to find this instance's variable name
**/
this.getInstanceName = function() {
if(this.instanceName == null)
{
for(z in window) {
if((window[z] instanceof myClass) && (window[z].uniqueProperty === this.uniqueProperty)) {
this.instanceName = z;
break;
}
}
}
return this.instanceName;
}
}
My vote! jquery.sortElements.js and simple jquery
Very simple, very easy, thanks nandhp...
$('th').live('click', function(){
var th = $(this), thIndex = th.index(), var table = $(this).parent().parent();
switch($(this).attr('inverse')){
case 'false': inverse = true; break;
case 'true:': inverse = false; break;
default: inverse = false; break;
}
th.attr('inverse',inverse)
table.find('td').filter(function(){
return $(this).index() === thIndex;
}).sortElements(function(a, b){
return $.text([a]) > $.text([b]) ?
inverse ? -1 : 1
: inverse ? 1 : -1;
}, function(){
// parentNode is the element we want to move
return this.parentNode;
});
inverse = !inverse;
});

But can I abort a Task (in .Net 4.0) in the same way not by cancellation mechanism. I want to kill the Task immediately.
Other answerers have told you not to do it. But yes, you can do it. You can supply Thread.Abort()
as the delegate to be called by the Task's cancellation mechanism. Here is how you could configure this:
class HardAborter
{
public bool WasAborted { get; private set; }
private CancellationTokenSource Canceller { get; set; }
private Task<object> Worker { get; set; }
public void Start(Func<object> DoFunc)
{
WasAborted = false;
// start a task with a means to do a hard abort (unsafe!)
Canceller = new CancellationTokenSource();
Worker = Task.Factory.StartNew(() =>
{
try
{
// specify this thread's Abort() as the cancel delegate
using (Canceller.Token.Register(Thread.CurrentThread.Abort))
{
return DoFunc();
}
}
catch (ThreadAbortException)
{
WasAborted = true;
return false;
}
}, Canceller.Token);
}
public void Abort()
{
Canceller.Cancel();
}
}
disclaimer: don't do this.
Here is an example of what not to do:
var doNotDoThis = new HardAborter();
// start a thread writing to the console
doNotDoThis.Start(() =>
{
while (true)
{
Thread.Sleep(100);
Console.Write(".");
}
return null;
});
// wait a second to see some output and show the WasAborted value as false
Thread.Sleep(1000);
Console.WriteLine("WasAborted: " + doNotDoThis.WasAborted);
// wait another second, abort, and print the time
Thread.Sleep(1000);
doNotDoThis.Abort();
Console.WriteLine("Abort triggered at " + DateTime.Now);
// wait until the abort finishes and print the time
while (!doNotDoThis.WasAborted) { Thread.CurrentThread.Join(0); }
Console.WriteLine("WasAborted: " + doNotDoThis.WasAborted + " at " + DateTime.Now);
Console.ReadKey();
You can also restore your downloaded Atlas Backup .wt
WiredTiger files (which unzips or untar as a restore
folder) to your local MongoDB.
First, make a backup of your /data/db
path. Call it /data_20200407/db
. Second, copy paste all the .wt
files from your Atlas Backup restore folder into your local /data/db
path. Restart your Ubuntu or MongoDB server. Start your Mongo shell and you should have those restored files there.
First, and most important - all Spring beans are managed - they "live" inside a container, called "application context".
Second, each application has an entry point to that context. Web applications have a Servlet, JSF uses a el-resolver, etc. Also, there is a place where the application context is bootstrapped and all beans - autowired. In web applications this can be a startup listener.
Autowiring happens by placing an instance of one bean into the desired field in an instance of another bean. Both classes should be beans, i.e. they should be defined to live in the application context.
What is "living" in the application context? This means that the context instantiates the objects, not you. I.e. - you never make new UserServiceImpl()
- the container finds each injection point and sets an instance there.
In your controllers, you just have the following:
@Controller // Defines that this class is a spring bean
@RequestMapping("/users")
public class SomeController {
// Tells the application context to inject an instance of UserService here
@Autowired
private UserService userService;
@RequestMapping("/login")
public void login(@RequestParam("username") String username,
@RequestParam("password") String password) {
// The UserServiceImpl is already injected and you can use it
userService.login(username, password);
}
}
A few notes:
applicationContext.xml
you should enable the <context:component-scan>
so that classes are scanned for the @Controller
, @Service
, etc. annotations.UserServiceImpl
should also be defined as bean - either using <bean id=".." class="..">
or using the @Service
annotation. Since it will be the only implementor of UserService
, it will be injected.@Autowired
annotation, Spring can use XML-configurable autowiring. In that case all fields that have a name or type that matches with an existing bean automatically get a bean injected. In fact, that was the initial idea of autowiring - to have fields injected with dependencies without any configuration. Other annotations like @Inject
, @Resource
can also be used.Is Powershell an option?

I try to avoid the URL
class and instead rely on URI
. Thus for things that need URL
where I would like to do Spring Resource like lookup with out Spring I do the following:
public static URL toURL(URI u, ClassLoader loader) throws MalformedURLException {
if ("classpath".equals(u.getScheme())) {
String path = u.getPath();
if (path.startsWith("/")){
path = path.substring("/".length());
}
return loader.getResource(path);
}
else if (u.getScheme() == null && u.getPath() != null) {
//Assume that its a file.
return new File(u.getPath()).toURI().toURL();
}
else {
return u.toURL();
}
}
To create a URI you can use URI.create(..)
. This way is also better because you control the ClassLoader
that will do the resource lookup.
I noticed some other answers trying to parse the URL as a String to detect the scheme. I think its better to pass around URI and use it to parse instead.

Further reading for any of the topics here: The Definitive Guide to Linux System Calls
I verified these using GNU Assembler (gas) on Linux.
x86-32 aka i386 Linux System Call convention:
In x86-32 parameters for Linux system call are passed using registers. %eax
for syscall_number. %ebx, %ecx, %edx, %esi, %edi, %ebp are used for passing 6 parameters to system calls.
The return value is in %eax
. All other registers (including EFLAGS) are preserved across the int $0x80
.
I took following snippet from the Linux Assembly Tutorial but I'm doubtful about this. If any one can show an example, it would be great.
If there are more than six arguments,
%ebx
must contain the memory location where the list of arguments is stored - but don't worry about this because it's unlikely that you'll use a syscall with more than six arguments.
For an example and a little more reading, refer to http://www.int80h.org/bsdasm/#alternate-calling-convention. Another example of a Hello World for i386 Linux using int 0x80
: Hello, world in assembly language with Linux system calls?
There is a faster way to make 32-bit system calls: using sysenter
. The kernel maps a page of memory into every process (the vDSO), with the user-space side of the sysenter
dance, which has to cooperate with the kernel for it to be able to find the return address. Arg to register mapping is the same as for int $0x80
. You should normally call into the vDSO instead of using sysenter
directly. (See The Definitive Guide to Linux System Calls for info on linking and calling into the vDSO, and for more info on sysenter
, and everything else to do with system calls.)
x86-32 [Free|Open|Net|DragonFly]BSD UNIX System Call convention:
Parameters are passed on the stack. Push the parameters (last parameter pushed first) on to the stack. Then push an additional 32-bit of dummy data (Its not actually dummy data. refer to following link for more info) and then give a system call instruction int $0x80
http://www.int80h.org/bsdasm/#default-calling-convention
(Note: x86-64 Mac OS X is similar but different from Linux. TODO: check what *BSD does)
Refer to section: "A.2 AMD64 Linux Kernel Conventions" of System V Application Binary Interface AMD64 Architecture Processor Supplement. The latest versions of the i386 and x86-64 System V psABIs can be found linked from this page in the ABI maintainer's repo. (See also the x86 tag wiki for up-to-date ABI links and lots of other good stuff about x86 asm.)
Here is the snippet from this section:
- User-level applications use as integer registers for passing the sequence %rdi, %rsi, %rdx, %rcx, %r8 and %r9. The kernel interface uses %rdi, %rsi, %rdx, %r10, %r8 and %r9.
- A system-call is done via the
syscall
instruction. This clobbers %rcx and %r11 as well as the %rax return value, but other registers are preserved.- The number of the syscall has to be passed in register %rax.
- System-calls are limited to six arguments, no argument is passed directly on the stack.
- Returning from the syscall, register %rax contains the result of the system-call. A value in the range between -4095 and -1 indicates an error, it is
-errno
.- Only values of class INTEGER or class MEMORY are passed to the kernel.
Remember this is from the Linux-specific appendix to the ABI, and even for Linux it's informative not normative. (But it is in fact accurate.)
This 32-bit int $0x80
ABI is usable in 64-bit code (but highly not recommended). What happens if you use the 32-bit int 0x80 Linux ABI in 64-bit code? It still truncates its inputs to 32-bit, so it's unsuitable for pointers, and it zeros r8-r11.
x86-32 Function Calling convention:
In x86-32 parameters were passed on stack. Last parameter was pushed first on to the stack until all parameters are done and then call
instruction was executed. This is used for calling C library (libc) functions on Linux from assembly.
Modern versions of the i386 System V ABI (used on Linux) require 16-byte alignment of %esp
before a call
, like the x86-64 System V ABI has always required. Callees are allowed to assume that and use SSE 16-byte loads/stores that fault on unaligned. But historically, Linux only required 4-byte stack alignment, so it took extra work to reserve naturally-aligned space even for an 8-byte double
or something.
Some other modern 32-bit systems still don't require more than 4 byte stack alignment.
x86-64 System V passes args in registers, which is more efficient than i386 System V's stack args convention. It avoids the latency and extra instructions of storing args to memory (cache) and then loading them back again in the callee. This works well because there are more registers available, and is better for modern high-performance CPUs where latency and out-of-order execution matter. (The i386 ABI is very old).
In this new mechanism: First the parameters are divided into classes. The class of each parameter determines the manner in which it is passed to the called function.
For complete information refer to : "3.2 Function Calling Sequence" of System V Application Binary Interface AMD64 Architecture Processor Supplement which reads, in part:
Once arguments are classified, the registers get assigned (in left-to-right order) for passing as follows:
- If the class is MEMORY, pass the argument on the stack.
- If the class is INTEGER, the next available register of the sequence %rdi, %rsi, %rdx, %rcx, %r8 and %r9 is used
So %rdi, %rsi, %rdx, %rcx, %r8 and %r9
are the registers in order used to pass integer/pointer (i.e. INTEGER class) parameters to any libc function from assembly. %rdi is used for the first INTEGER parameter. %rsi for 2nd, %rdx for 3rd and so on. Then call
instruction should be given. The stack (%rsp
) must be 16B-aligned when call
executes.
If there are more than 6 INTEGER parameters, the 7th INTEGER parameter and later are passed on the stack. (Caller pops, same as x86-32.)
The first 8 floating point args are passed in %xmm0-7, later on the stack. There are no call-preserved vector registers. (A function with a mix of FP and integer arguments can have more than 8 total register arguments.)
Variadic functions (like printf
) always need %al
= the number of FP register args.
There are rules for when to pack structs into registers (rdx:rax
on return) vs. in memory. See the ABI for details, and check compiler output to make sure your code agrees with compilers about how something should be passed/returned.
Note that the Windows x64 function calling convention has multiple significant differences from x86-64 System V, like shadow space that must be reserved by the caller (instead of a red-zone), and call-preserved xmm6-xmm15. And very different rules for which arg goes in which register.
The black hole register _
is the /dev/null
of registers.
I use it in my vimrc to allow deleting single characters without updating the default register:
noremap x "_x
and to paste in visual mode without updating the default register:
vnoremap p "_dP
System.Environment.TickCount and the System.Diagnostics.Stopwatch class are two that work well for finer resolution and straightforward usage.

Unfortunately, adding the javaee-(web)-api as a dependency doesn't give you the Javadoc or the Source to the Servlet Api to browse them from within the IDE. This is also the case for all other dependencies (JPA, EJB, ...) If you need the Servlet API sources/javadoc, you can add the following to your pom.xml (works at least for JBoss&Glassfish):
Repository:
<repository>
<id>jboss-public-repository-group</id>
<name>JBoss Public Repository Group</name>
<url>https://repository.jboss.org/nexus/content/groups/public/</url>
</repository>
Dependency:

<artifactId>jboss-servlet-api_3.0_spec</artifactId>
<version>1.0.0.Beta2</version>
<scope>provided</scope>
</dependency>
I completely removed the javaee-api from my dependencies and replaced it with the discrete parts (javax.ejb, javax.faces, ...) to get the sources and Javadocs for all parts of Java EE 6.
EDIT:
Here is the equivalent Glassfish dependency (although both dependencies should work, no matter what appserver you use).

<groupId>org.glassfish</groupId>
<artifactId>javax.servlet</artifactId>

This should work:

if [[ -d $a ]]; then
echo "$a is a Dir"
elif [[ -f $a ]]; then

else
echo "Invalid path"

As @substack corrected me in #node, the new streams API in Node v10 makes this easier:
const Readable = require('stream').Readable;
const s = new Readable();
s._read = () => {}; // redundant? see update below
s.push('your text here');
s.push(null);
… after which you can freely pipe it or otherwise pass it to your intended consumer.
It's not as clean as the resumer one-liner, but it does avoid the extra dependency.
(Update: in v0.10.26 through v9.2.1 so far, a call to push
directly from the REPL prompt will crash with a not implemented
exception if you didn't set _read
. It won't crash inside a function or a script. If inconsistency makes you nervous, include the noop
.)
const myMap = new Map(
Object
.keys(myObj)
.map(
key => [key, myObj[key]]
)
)
git checkout {branch-name} -- {file-name}
This will use the file from the branch of choice.
I like this because posh-git
autocomplete works great with this. It also removes any ambiguity as to which branch is remote and which is local.
And --theirs
didn't work for me anyways.
You can treat a submodule exactly like an ordinary repository. To propagate your changes upstream just commit and push as you would normally within that directory.
RESTful API (Route):
rtr.route('/testing')
.get((req, res)=>{
res.render('test')
})
.post((req, res, next)=>{
res.render('test')
})
AJAX Code:
$(function(){
$('#anyid').on('click', function(e){
e.preventDefault()
$.ajax({
url: '/testing',
method: 'GET',
contentType: 'application/json',
success: function(res){
console.log('GET Request')
}
})
})
$('#anyid').on('submit', function(e){
e.preventDefault()
$.ajax({

contentType: 'application/json',
data: JSON.stringify({
info: "put data here to pass in JSON format."
}),
success: function(res){
console.log('POST Request')
}
})
})
})
You can use the :not
filter selector:
$('foo:not(".someClass")')
Or not()
method:
$('foo').not(".someClass")
More Info:
You can use map
:
List<String> names =
personList.stream()
.map(Person::getName)
.collect(Collectors.toList());
EDIT :
In order to combine the Lists of friend names, you need to use flatMap
:
List<String> friendNames =
personList.stream()
.flatMap(e->e.getFriends().stream())
.collect(Collectors.toList());
I always recommend using Apache commons since it will most likely be better than one you can write on your own. Plus you can then do 'real' work rather then reinventing.
The class you are interested in is the Null Comparator. It allows you to make nulls high or low. You also give it your own comparator to use when the two values are not null.
In your case you can have a static member variable that does the comparison and then your compareTo
method just references that.
Somthing like
class Metadata implements Comparable<Metadata> {
private String name;
private String value;
static NullComparator nullAndCaseInsensitveComparator = new NullComparator(
new Comparator<String>() {
@Override
public int compare(String o1, String o2) {
// inputs can't be null
return o1.compareToIgnoreCase(o2);
}
});
@Override
public int compareTo(Metadata other) {
if (other == null) {
return 1;
}
int res = nullAndCaseInsensitveComparator.compare(name, other.name);
if (res != 0)
return res;
return nullAndCaseInsensitveComparator.compare(value, other.value);
}
}
Even if you decide to roll your own, keep this class in mind since it is very useful when ordering lists thatcontain null elements.
The part about not being able to use the Back button is a common misinterpretation. window.location.replace(URL) throws out the top ONE entry from the page history list, by overwriting it with the new entry, so the user can't easily go Back to that ONE particular webpage. The function does NOT wipe out the entire page history list, nor does it make the Back button completely non-functional.
(NO function nor combination of parameters that I know of can change or overwrite history list entries that you don't own absolutely for certain - browsers generally impelement this security limitation by simply not even defining any operation that might at all affect any entry other than the top one in the page history list. I shudder to think what sorts of dastardly things malware might do if such a function existed.)
If you really want to make the Back button non-functional (probably not "user friendly": think again if that's really what you want to do), "open" a brand new window. (You can "open" a popup that doesn't even have a "Back" button too ...but popups aren't very popular these days:-) If you want to keep your page showing no matter what the user does (again the "user friendliness" is questionable), set up a window.onunload handler that just reloads your page all over again clear from the very beginning every time.
If your /tmp
mount on a linux filesystem is mounted as overflow (often sized at 1MB), this is likely due to you not specifying /tmp
as its own partition and your root filesystem filled up and /tmp
was remounted as a fallback.
To fix this after you’ve cleared space, just unmount the fallback and it should remount at its original point:
sudo umount overflow
For Windows 10, 5.29.18 :
Using command promt I just got in the emulator directory:
cd C:\Android\sdk\emulator
and then typed the command:
emulator -avd Nexus_S_API_27
Nexus_S_API_27
is the name of my custom emulator.
Othewize it will abuse :
PANIC: Missing emulator engine program for 'x86' CPU.
I am having this issue as well. Here is the code that is getting inserted for the close button:
When I turn off the style="display:none:" on the button, then the close button appears. So for some reason that display:none; is getting set, and I don't see how to control that. So another way to address this might be to simply override the display:none. Don't see how to do that though.
I note that the answer posted by KyleMit does work, but makes a different looking X button.
I also note that this issue does not affect all dialogs on my pages, but just some of them. Some dialogs work as expected; other have no title (ie, the span containing the title is empty) while the close button is present.
I am thinking something is seriously wrong and it might not the time for 1.10.x.
But after further work, I discovered that in some cases the titles were not getting set properly, and after fixing that, the X close button reappeared as it should be.
I used to set the titles like this:
('#ui-dialog-title-ac-popup').text('Add Admin Comments for #' + $ac_userid);
That id does not exist in my code, but is created apparently by jquery from ac-popup and ui-dialog-title. Kind of a kludge. But as I said that no longer works, and I have to use the following instead:
$('.ui-dialog-title').text('Add Admin Comments for #' + $ac_userid);
After doing that, the missing button issue seems to be better, although I am not sure if they are definitely related.
Use the BigInteger
class that is a part of the Java library.
http://java.sun.com/j2se/1.5.0/docs/api/java/math/BigInteger.html
The List<>
class does guarantee ordering - things will be retained in the list in the order you add them, including duplicates, unless you explicitly sort the list.
According to MSDN:
...List "Represents a strongly typed list of objects that can be accessed by index."
The index values must remain reliable for this to be accurate. Therefore the order is guaranteed.
You might be getting odd results from your code if you're moving the item later in the list, as your Remove()
will move all of the other items down one place before the call to Insert()
.
Can you boil your code down to something small enough to post?
Use --build-arg

If you are passing two argument then add --build-arg

--build-arg number_of_replicas=2 \
--no-cache .
.model small

For bootstrap datepicker you can use:
$("#inputWithDatePicer").data('datepicker').getFormattedDate('yyyy-mm-dd');
Although they both are very much alike there is a minor difference :
var array = ["a", "b", "c"];
array["abc"] = 123;
console.log("Standard for loop:");
for (var index = 0; index < array.length; index++)
{
console.log(" array[" + index + "] = " + array[index]); //Standard for loop
}
in this case the output is :
STANDARD FOR LOOP:
ARRAY[0] = A
ARRAY[1] = B
ARRAY[2] = C
console.log("For-in loop:");
for (var key in array)
{
console.log(" array[" + key + "] = " + array[key]); //For-in loop output
}
while in this case the output is:
FOR-IN LOOP:
ARRAY[1] = B
ARRAY[2] = C
ARRAY[10] = D
ARRAY[ABC] = 123
private boolean hasContent(EditText et) {
return (et.getText().toString().trim().length() > 0);
}
Either one should work OK. In fact, System.Threading.Timer uses System.Timers.Timer internally.
Having said that, it's easy to misuse System.Timers.Timer. If you don't store the Timer object in a variable somewhere, then it is liable to be garbage collected. If that happens, your timer will no longer fire. Call the Dispose method to stop the timer, or use the System.Threading.Timer class, which is a slightly nicer wrapper.
What problems have you seen so far?
Probably the shortest version:
[System.Collections.ArrayList]$someArray
It is also faster because it does not call relatively expensive New-Object
.
I believe you can only add variables to the Watch window while the debugger is stopped on a breakpoint. If you set a breakpoint on a step, you should be able to enter variables into the Watch window when the breakpoint is hit. You can select the first empty row in the Watch window and enter the variable name (you may or may not get some Intellisense there, I can't remember how well that works.)
You can use Git GUI on Windows, see instructions:
Best option is create new table with same properties
CREATE TABLE <NEW.NAME.TABLE> LIKE <TABLE.CRASHED>;
INSERT INTO <NEW.NAME.TABLE> SELECT * FROM <TABLE.CRASHED>;
Rename NEW.NAME.TABLE and TABLE.CRASH
RENAME TABLE <TABLE.CRASHED> TO <TABLE.CRASHED.BACKUP>;
RENAME TABLE <NEW.NAME.TABLE> TO <TABLE.CRASHED>;
After work well, delete
DROP TABLE <TABLE.CRASHED.BACKUP>;
To execute a file in the current directory, the syntax to use is: ./foo

to specify your own output filename. An example of this would be: cc helloworld.c -o helloworld.exe
.
You can just create your own .white
class and add it to the glyphicon element.
.white, .white a {
color: #fff;
}
<i class="glyphicon glyphicon-home white"></i>
To get the index
values as a list
/list
of tuple
s for Index
/MultiIndex
do:
df.index.values.tolist() # an ndarray method, you probably shouldn't depend on this
or
list(df.index.values) # this will always work in pandas
Try using the following on the JavaScript side:
window.location.href = '@Url.Action("Index", "Controller")';
If you want to pass parameters to the @Url.Action
, you can do this:
var reportDate = $("#inputDateId").val();//parameter
var url = '@Url.Action("Index", "Controller", new {dateRequested = "findme"})';
window.location.href = url.replace('findme', reportDate);
Further to @montrealmike 's answer, can I just add my adaptation?
I did this:
.container {
overflow: hidden;
....
}
#sidebar {
margin-bottom: -101%;
padding-bottom: 101%;
....
}
I did the "101%" thing to cater for the (ultra rare) possibility that somebody may be viewing the site on a huge screen with a height more than 5000px!
Great answer though, montrealmike. It worked perfectly for me.
Check MediaQuery
class
For example, to learn the size of the current media (e.g., the window containing your app), you can read the
MediaQueryData.size
property from theMediaQueryData
returned byMediaQuery.of
:MediaQuery.of(context).size
.
So you can do the following:
new Container(
height: MediaQuery.of(context).size.height/2,
.. )
XAML
<Popup Name="myPopup">
<TextBlock Name="myPopupText"
Background="LightBlue"
Foreground="Blue">
Popup Text
</TextBlock>
</Popup>
c#
Popup codePopup = new Popup();
TextBlock popupText = new TextBlock();
popupText.Text = "Popup Text";
popupText.Background = Brushes.LightBlue;
popupText.Foreground = Brushes.Blue;
codePopup.Child = popupText;
you can find more details about the Popup Control from MSDN documentation.
You are running your HTML from a different host than the host you are requesting. Because of this, you are getting blocked by the same origin policy.
One way around this is to use JSONP. This allows cross-site requests.
In JSON, you are returned:
{a: 5, b: 6}
In JSONP, the JSON is wrapped in a function call, so it becomes a script, and not an object.
callback({a: 5, b: 6})
You need to edit your REST service to accept a parameter called callback
, and then to use the value of that parameter as the function name. You should also change the content-type
to application/javascript
.
For example: http://localhost:8080/restws/json/product/get?callback=process
should output:
process({a: 5, b: 6})
In your JavaScript, you will need to tell jQuery to use JSONP. To do this, you need to append ?callback=?
to the URL.
$.getJSON("http://localhost:8080/restws/json/product/get?callback=?",
function(data) {
alert(data);
});
If you use $.ajax
, it will auto append the ?callback=?
if you tell it to use jsonp
.
$.ajax({
type: "GET",
dataType: "jsonp",
url: "http://localhost:8080/restws/json/product/get",
success: function(data){
alert(data);
}
});
Might want to try putting the PHP function on another PHP page, and use an AJAX call to set the variable.
This is how I handle this, without using exceptions.
import sys
if sys.version_info.major > 2: # Python 3 or later
from urllib.parse import quote
else: # Python 2
from urllib import quote
Try something like:
WHERE (column LIKE '%this%' OR column LIKE '%that%') AND something = else
What language?? There are different tools for almost every imaginable programming language, since they all have different syntactic rules and conventions.
Good ol' indent
is a nice, customizable, command-line utility to format C and C++ programs.
Well, its not compulsory to restart the emulator you can also reset adb from eclipse itself.
1.) Go to DDMS and there is a reset adb option, please see the image below.
2.) You can restart adb manually from command prompt
run->cmd->your_android_sdk_path->platform-tools>
Then write the below commands.
adb kill-server - To kill the server forcefully
adb start-server - To start the server
UPDATED:
F:\android-sdk-windows latest\platform-tools>adb kill-server
F:\android-sdk-windows latest\platform-tools>adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
DateTime is immutable. That means you cannot change it's state and have to assign the result of an operation to a variable.
endDate = endDate.AddDays(addedDays);
finishAffinity()
added in API 16. Use ActivityCompat.finishAffinity()
in previous versions. When you will launch any activity using intent and finish the current activity. Now use ActivityCompat.finishAffinity()
instead finish()
. it will finish all stacked activity below current activity. It works fine for me.
Simply add the class img-responsive
to your img
tag, it is applicable in bootstrap 3 onward!
I spent a lot of time researching this and learning how it all works, after really messing up the event triggers. Since there was so much scattered info I decided to share what I have found to work all in one place, step by step as follows:
1) Open VBA Editor, under VBA Project (YourWorkBookName.xlsm) open Microsoft Excel Object and select the Sheet to which the change event will pertain.
2) The default code view is "General." From the drop-down list at the top middle, select "Worksheet."
3) Private Sub Worksheet_SelectionChange is already there as it should be, leave it alone. Copy/Paste Mike Rosenblum's code from above and change the .Range reference to the cell for which you are watching for a change (B3, in my case). Do not place your Macro yet, however (I removed the word "Macro" after "Then"):
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Me.Range("H5")) Is Nothing Then
End Sub
or from the drop-down list at the top left, select "Change" and in the space between Private Sub and End Sub, paste If Not Intersect(Target, Me.Range("H5")) Is Nothing Then
4) On the line after "Then" turn off events so that when you call your macro, it does not trigger events and try to run this Worksheet_Change again in a never ending cycle that crashes Excel and/or otherwise messes everything up:
Application.EnableEvents = False
5) Call your macro
Call YourMacroName
6) Turn events back on so the next change (and any/all other events) trigger:
Application.EnableEvents = True
7) End the If block and the Sub:
End If
End Sub
The entire code:
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Me.Range("B3")) Is Nothing Then
Application.EnableEvents = False
Call UpdateAndViewOnly
Application.EnableEvents = True
End If
End Sub
This takes turning events on/off out of the Modules which creates problems and simply lets the change trigger, turns off events, runs your macro and turns events back on.
This should solve your problem, you should try to run the following below:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
