You should inspect full trace very carefully,
I've a server socket application and fixed a java.net.SocketException: Connection reset
case.
In my case it happens while reading from a clientSocket Socket
object which is closed its connection because of some reason. (Network lost,firewall or application crash or intended close)
Actually I was re-establishing connection when I got an error while reading from this Socket object.
Socket clientSocket = ServerSocket.accept();
is = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
int readed = is.read(); // WHERE ERROR STARTS !!!
The interesting thing is for my JAVA Socket
if a client connects to my ServerSocket
and close its connection without sending anything is.read()
is being called repeatedly.It seems because of being in an infinite while loop for reading from this socket you try to read from a closed connection.
If you use something like below for read operation;
while(true)
{
Receive();
}
Then you get a stackTrace something like below on and on
java.net.SocketException: Socket is closed
at java.net.ServerSocket.accept(ServerSocket.java:494)
What I did is just closing ServerSocket and renewing my connection and waiting for further incoming client connections
String Receive() throws Exception
{
try {
int readed = is.read();
....
}catch(Exception e)
{
tryReConnect();
logit(); //etc
}
//...
}
This reestablises my connection for unknown client socket losts
private void tryReConnect()
{
try
{
ServerSocket.close();
//empty my old lost connection and let it get by garbage col. immediately
clientSocket=null;
System.gc();
//Wait a new client Socket connection and address this to my local variable
clientSocket= ServerSocket.accept(); // Waiting for another Connection
System.out.println("Connection established...");
}catch (Exception e) {
String message="ReConnect not successful "+e.getMessage();
logit();//etc...
}
}
I couldn't find another way because as you see from below image you can't understand whether connection is lost or not without a try and catch
,because everything seems right . I got this snapshot while I was getting Connection reset
continuously.
>>> lis=[[180.0], [173.8], [164.2], [156.5], [147.2], [138.2]]
>>> [x[0] for x in lis]
[180.0, 173.8, 164.2, 156.5, 147.2, 138.2]
use this:
bytesRead = responseStream.ReadAsync(buffer, 0, Length).Result;
You might want to use the Event Log ! Here's how to access it from C# http://support.microsoft.com/kb/307024/en
But whatever is the method that you will use, I'd recommend to output to a file every time something is appended to the log rather than when your process exits, so you won't lose data in the case of crash or if your process is killed.
Given
volumes:
- /dir/on/host:/var/www/html
if /dir/on/host
doesn't exist, it is created on the host and the empty content is mounted in the container at /var/www/html
. Whatever content you had before in /var/www/html
inside the container is inaccessible, until you unmount the volume; the new mount is hiding the old content.
My answer is a slight variation for those who just want today's date in the local timezone in the YYYY-MM-DD format.
Let me be clear:
My Goal: get today's date in the user's timezone but formatted as ISO8601 (YYYY-MM-DD)
Here is the code:
new Date().toLocaleDateString("sv") // "2020-02-23" //
This works because the Sweden locale uses the ISO 8601 format.
For naming template parameters, typename
and class
are equivalent. §14.1.2:
There is no semantic difference between class and typename in a template-parameter.
typename
however is possible in another context when using templates - to hint at the compiler that you are referring to a dependent type. §14.6.2:
A name used in a template declaration or definition and that is dependent on a template-parameter is assumed not to name a type unless the applicable name lookup finds a type name or the name is qualified by the keyword typename.
Example:
typename some_template<T>::some_type
Without typename
the compiler can't tell in general whether you are referring to a type or not.
When MS-DOS and Windows 3.1 operated in 16-bit mode, an Intel 8086 word was 16 bits, a Microsoft WORD was 16 bits, a Microsoft DWORD was 32 bits, and a typical compiler's unsigned int was 16 bits.
When Windows NT operated in 32-bit mode, an Intel 80386 word was 32 bits, a Microsoft WORD was 16 bits, a Microsoft DWORD was 32 bits, and a typical compiler's unsigned int was 32 bits. The names WORD and DWORD were no longer self-descriptive but they preserved the functionality of Microsoft programs.
When Windows operates in 64-bit mode, an Intel word is 64 bits, a Microsoft WORD is 16 bits, a Microsoft DWORD is 32 bits, and a typical compiler's unsigned int is 32 bits. The names WORD and DWORD are no longer self-descriptive, AND an unsigned int no longer conforms to the principle of least surprises, but they preserve the functionality of lots of programs.
I don't think WORD or DWORD will ever change.
She had a space in one of the folder names in her path, and no quotes around it.
If you want to modify the original array instead of returning a new array, use .push()
...
array1.push.apply(array1, array2);
array1.push.apply(array1, array3);
I used .apply
to push the individual members of arrays 2
and 3
at once.
or...
array1.push.apply(array1, array2.concat(array3));
To deal with large arrays, you can do this in batches.
for (var n = 0, to_add = array2.concat(array3); n < to_add.length; n+=300) {
array1.push.apply(array1, to_add.slice(n, n+300));
}
If you do this a lot, create a method or function to handle it.
var push_apply = Function.apply.bind([].push);
var slice_call = Function.call.bind([].slice);
Object.defineProperty(Array.prototype, "pushArrayMembers", {
value: function() {
for (var i = 0; i < arguments.length; i++) {
var to_add = arguments[i];
for (var n = 0; n < to_add.length; n+=300) {
push_apply(this, slice_call(to_add, n, n+300));
}
}
}
});
and use it like this:
array1.pushArrayMembers(array2, array3);
var push_apply = Function.apply.bind([].push);_x000D_
var slice_call = Function.call.bind([].slice);_x000D_
_x000D_
Object.defineProperty(Array.prototype, "pushArrayMembers", {_x000D_
value: function() {_x000D_
for (var i = 0; i < arguments.length; i++) {_x000D_
var to_add = arguments[i];_x000D_
for (var n = 0; n < to_add.length; n+=300) {_x000D_
push_apply(this, slice_call(to_add, n, n+300));_x000D_
}_x000D_
}_x000D_
}_x000D_
});_x000D_
_x000D_
var array1 = ['a','b','c'];_x000D_
var array2 = ['d','e','f'];_x000D_
var array3 = ['g','h','i'];_x000D_
_x000D_
array1.pushArrayMembers(array2, array3);_x000D_
_x000D_
document.body.textContent = JSON.stringify(array1, null, 4);

zsh has a builtin command emulate
which can emulate different shells by setting the appropriate options, although csh will never be fully emulated.
emulate bash
perform commands
emulate -R zsh
The -R flag restores all the options to their default values for that shell.
See: zsh manual
Here is the syntax to create a trigger:
CREATE TRIGGER trigger_name
ON { table | view }
[ WITH ENCRYPTION ]
{
{ { FOR | AFTER | INSTEAD OF } { [ INSERT ] [ , ] [ UPDATE ] [ , ] [ DELETE ] }
[ WITH APPEND ]
[ NOT FOR REPLICATION ]
AS
[ { IF UPDATE ( column )
[ { AND | OR } UPDATE ( column ) ]
[ ...n ]
| IF ( COLUMNS_UPDATED ( ) { bitwise_operator } updated_bitmask )
{ comparison_operator } column_bitmask [ ...n ]
} ]
sql_statement [ ...n ]
}
}
If you want to use On Update you only can do it with the IF UPDATE ( column )
section. That's not possible to do what you are asking.
Can't you do this with just one heap? Update: no. See the comment.
Invariant: After reading 2*n
inputs, the min-heap holds the n
largest of them.
Loop: Read 2 inputs. Add them both to the heap, and remove the heap's min. This reestablishes the invariant.
So when 2n
inputs have been read, the heap's min is the nth largest. There'll need to be a little extra complication to average the two elements around the median position and to handle queries after an odd number of inputs.
You can use df.plot.scatter, and pass an array to c= argument defining the color of each point:
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
df = pd.DataFrame(np.random.normal(10,1,30).reshape(10,3), index = pd.date_range('2010-01-01', freq = 'M', periods = 10), columns = ('one', 'two', 'three'))
df['key1'] = (4,4,4,6,6,6,8,8,8,8)
colors = np.where(df["key1"]==4,'r','-')
colors[df["key1"]==6] = 'g'
colors[df["key1"]==8] = 'b'
print(colors)
df.plot.scatter(x="one",y="two",c=colors)
plt.show()
Try This:

class Thing {
public int value;
public Thing (int x) {
value = x;
}
equals (Thing x) {
if (x.value == value) return true;
return false;
}
}
You must write:
class Thing {
public int value;
public Thing (int x) {
value = x;
}
public boolean equals (Object o) {
Thing x = (Thing) o;
if (x.value == value) return true;
return false;
}
}
Now it works ;)
You can get value of id,name or value in this way. class name my_class
var id_value = $('.my_class').$(this).attr('id'); //get id value
var name_value = $('.my_class').$(this).attr('name'); //get name value
var value = $('.my_class').$(this).attr('value'); //get value any input or tag
If your plan is to do this as part of a query, please don't do that (a). Seriously, it's a performance killer. There may be situations where you don't care about performance (such as one-off migration jobs to split the fields allowing better performance in future) but, if you're doing this regularly for anything other than a mickey-mouse database, you're wasting resources.
If you ever find yourself having to process only part of a column in some way, your DB design is flawed. It may well work okay on a home address book or recipe application or any of myriad other small databases but it will not be scalable to "real" systems.
Store the components of the name in separate columns. It's almost invariably a lot faster to join columns together with a simple concatenation (when you need the full name) than it is to split them apart with a character search.
If, for some reason you cannot split the field, at least put in the extra columns and use an insert/update trigger to populate them. While not 3NF, this will guarantee that the data is still consistent and will massively speed up your queries. You could also ensure that the extra columns are lower-cased (and indexed if you're searching on them) at the same time so as to not have to fiddle around with case issues.
And, if you cannot even add the columns and triggers, be aware (and make your client aware, if it's for a client) that it is not scalable.
(a) Of course, if your intent is to use this query to fix the schema so that the names are placed into separate columns in the table rather than the query, I'd consider that to be a valid use. But I reiterate, doing it in the query is not really a good idea.
Note
Mutation events have been deprecated since this post was written, and may not be supported by all browsers. Instead, use a mutation observer.
Yes you can. DOM L2 Events module defines mutation events; one of them - DOMAttrModified is the one you need. Granted, these are not widely implemented, but are supported in at least Gecko and Opera browsers.
Try something along these lines:
document.documentElement.addEventListener('DOMAttrModified', function(e){
if (e.attrName === 'style') {
console.log('prevValue: ' + e.prevValue, 'newValue: ' + e.newValue);
}
}, false);
document.documentElement.style.display = 'block';
You can also try utilizing IE's "propertychange" event as a replacement to DOMAttrModified
. It should allow to detect style
changes reliably.
It looks like API level 11 has support for what you need. See WebViewClient.shouldInterceptRequest()
.
Here is an example implementation, which would make this process seamless (Borrowed from AngularJs)
var CookieReader = (function(){
var lastCookies = {};
var lastCookieString = '';
function safeGetCookie() {
try {
return document.cookie || '';
} catch (e) {
return '';
}
}
function safeDecodeURIComponent(str) {
try {
return decodeURIComponent(str);
} catch (e) {
return str;
}
}
function isUndefined(value) {
return typeof value === 'undefined';
}
return function () {
var cookieArray, cookie, i, index, name;
var currentCookieString = safeGetCookie();
if (currentCookieString !== lastCookieString) {
lastCookieString = currentCookieString;
cookieArray = lastCookieString.split('; ');
lastCookies = {};
for (i = 0; i < cookieArray.length; i++) {
cookie = cookieArray[i];
index = cookie.indexOf('=');
if (index > 0) { //ignore nameless cookies
name = safeDecodeURIComponent(cookie.substring(0, index));
if (isUndefined(lastCookies[name])) {
lastCookies[name] = safeDecodeURIComponent(cookie.substring(index + 1));
}
}
}
}
return lastCookies;
};
})();
I got this error recently by introducing an old plugin to wordpress. It loaded an older version of jquery, which happened to be placed before the jquery mouse file. There was no jquery widget file loaded with the second version, which caused the error.
No error for using the extra jquery library -- that's a problem especially if a silent fail might have happened, causing a not so silent fail later on.
A potential way around it for wordpress might be to be explicit about the dependencies that way the jquery mouse would follow the widget which would follow the correct core leaving the other jquery to be loaded afterwards. Still might cause a production error later if you don't catch that and change the default function for jquery for the second version in all the files associated with it.

According to my experience, in console apps the easiest way to read the last key pressed is as follows (Example with arrow keys):
ConsoleKey readKey = Console.ReadKey ().Key;
if (readKey == ConsoleKey.LeftArrow) {
<Method1> (); //Do something
} else if (readKey == ConsoleKey.RightArrow) {
<Method2> (); //Do something
}
I use to avoid loops, instead I write the code above within a method, and I call it at the end of both "Method1" and "Method2", so, after executing "Method1" or "Method2", Console.ReadKey().Key is ready to read the keys again.
Angular no longer supports --env instead you have to use

The Simulator does not run ARM code, ONLY x86 code. Unless you have the raw source code from Apple, you won't see the App Store on the Simulator.
The app you write you will be able to test in the Simulator by running it directly from Xcode even if you don't have a developer account. To test your app on an actual device, you will need to be apart of the Apple Developer program.
Well...there are several ways to interpret this question.
The first way and the way I think you mean is to simply alter the display size so all images display the same size. For this, I would actually use CSS and not JavaScript. Simply create a class that has the appropriate width and height values set, and make all <img>
tags use this class.
A second way is that you want to preserve the aspect ration of all the images, but scale the display size to a sane value. There is a way to access this in JavaScript, but I'll need a bit to write up a quick code sample.
The third way, and I hope you don't mean this way, is to alter the actual size of the image. This is something you'd have to do on the server side, as not only is JavaScript unable to create images, but it wouldn't make any sense, as the full sized image has already been sent.
From my experience in React Native, you can also restart your CLI and this error goes away.
If your exe takes arguments,
start MyApp.exe -arg1 -arg2
I also faced the same issue with Eclipse when I ran the clean build with Maven, but there is a simple solution for this issue. We just need to run Maven update and then build or direct run the application. I hope it will solve the problem.
Try the following (calling clearAllEditTextFocuses();
)
private final boolean clearAllEditTextFocuses() {
View v = getCurrentFocus();
if(v instanceof EditText) {
final FocusedEditTextItems list = new FocusedEditTextItems();
list.addAndClearFocus((EditText) v);
//Focus von allen EditTexten entfernen
boolean repeat = true;
do {
v = getCurrentFocus();
if(v instanceof EditText) {
if(list.containsView(v))
repeat = false;
else list.addAndClearFocus((EditText) v);
} else repeat = false;
} while(repeat);
final boolean result = !(v instanceof EditText);
//Focus wieder setzen
list.reset();
return result;
} else return false;
}
private final static class FocusedEditTextItem {
private final boolean focusable;
private final boolean focusableInTouchMode;
@NonNull
private final EditText editText;
private FocusedEditTextItem(final @NonNull EditText v) {
editText = v;
focusable = v.isFocusable();
focusableInTouchMode = v.isFocusableInTouchMode();
}
private final void clearFocus() {
if(focusable)
editText.setFocusable(false);
if(focusableInTouchMode)
editText.setFocusableInTouchMode(false);
editText.clearFocus();
}
private final void reset() {
if(focusable)
editText.setFocusable(true);
if(focusableInTouchMode)
editText.setFocusableInTouchMode(true);
}
}
private final static class FocusedEditTextItems extends ArrayList<FocusedEditTextItem> {
private final void addAndClearFocus(final @NonNull EditText v) {
final FocusedEditTextItem item = new FocusedEditTextItem(v);
add(item);
item.clearFocus();
}
private final boolean containsView(final @NonNull View v) {
boolean result = false;
for(FocusedEditTextItem item: this) {
if(item.editText == v) {
result = true;
break;
}
}
return result;
}
private final void reset() {
for(FocusedEditTextItem item: this)
item.reset();
}
}
I had this question, but with a twist - I was trying to log different content to different files. I had information for a LowLevel debug log, and a HighLevel user log. I wanted the LowLevel to go to only one file, and the HighLevel to go to both a file, and a syslogd.
My solution was to configure the 3 appenders, and then setup the logging like this:
log4j.threshold=ALL
log4j.rootLogger=,LowLogger
log4j.logger.HighLevel=ALL,Syslog,HighLogger
log4j.additivity.HighLevel=false
The part that was difficult for me to figure out was that the 'log4j.logger' could have multiple appenders listed. I was trying to do it one line at a time.
Hope this helps someone at some point!
I guess you are using Rails 4. If so, the needed parameters must be marked as required.
You might want to do it like this:
class UsersController < ApplicationController
def create
@user = User.new(user_params)
# ...
end
private
def user_params
params.require(:user).permit(:username, :email, :password, :salt, :encrypted_password)
end
end
There may be two causes:
It is case-sensitive: DataFrame .... Dataframe, dataframe will not work.
You have not install pandas (pip install pandas
) in the python path.
It allows servlets to have multiple servlet mappings:
<servlet>
<servlet-name>Servlet1</servlet-name>
<servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/bill</url-pattern>
</servlet-mapping>
It allows filters to be mapped on the particular servlet:
<filter-mapping>
<filter-name>Filter1</filter-name>
<servlet-name>Servlet1</servlet-name>
</filter-mapping>
Your proposal would support neither of them. Note that the web.xml
is read and parsed only once during application's startup, not on every HTTP request as you seem to think.
Since Servlet 3.0, there's the @WebServlet
annotation which minimizes this boilerplate:
@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {
Generate a number in the range from 100000

If that were a C program, I would say neither. The compiler will output exactly the same code. Since it's not, I say measure it. Really though, it's not about which loop construct is faster, since that's a miniscule amount of time savings. It's about which loop construct is easier to maintain. In the case you showed, a for loop is more appropriate because it's what other programmers (including future you, hopefully) will expect to see there.
ListBuffer
is a mutable list which has constant-time append, and constant-time conversion into a List
.
List
is immutable and has constant-time prepend and linear-time append.
How you construct your list depends on the algorithm you'll use the list for and the order in which you get the elements to create it.
For instance, if you get the elements in the opposite order of when they are going to be used, then you can just use a List
and do prepends. Whether you'll do so with a tail-recursive function, foldLeft
, or something else is not really relevant.
If you get the elements in the same order you use them, then a ListBuffer
is most likely a preferable choice, if performance is critical.
But, if you are not on a critical path and the input is low enough, you can always reverse
the list later, or just foldRight
, or reverse
the input, which is linear-time.
What you DON'T do is use a List
and append to it. This will give you much worse performance than just prepending and reversing at the end.
Try this:
<?php
$str = "This is some <b>bold</b> text.";
echo htmlspecialchars($str);
?>
Assuming your ints are 0, 375, 668,5 and 6:
{
"Id": "610",
"Name": "15",
"Description": "1.99",
"ItemModList": [
0,
375,
668,
5,
6
]
}
I suggest that you change "Id": "610" to "Id": 610 since it is a integer/long and not a string. You can read more about the JSON format and examples here http://json.org/
Windows has two different settings in which priority is established. There is the metric value which you have already set in the adapter settings, and then there is the connection priority in the network connections settings.
To change the priority of the connections:
Making it open from rtl isn't good for user experience, to make it responsive to the user locale I just added the following line to my DrawerLayout parameters:
android:layoutDirection="locale"
Added it to my AppBarLayout to make the hamburger layout match the drawer opening direction too.
You're looking for http_build_query()
.
Yes, this is possible. According to the SQLite FAQ:
A column declared
INTEGER PRIMARY KEY
will autoincrement.
Follow this steps:
-Build
-Generate Signed Apk
-Create new
Then fill up "New Key Store" form. If you wand to change .jnk file destination then chick on destination and give a name to get Ok button. After finishing it you will get "Key store password", "Key alias", "Key password" Press next and change your the destination folder. Then press finish, thats all. :)
We can access super class elements by using super keyword
Consider we have two classes, Parent class and Child class, with different implementations of method foo. Now in child class if we want to call the method foo of parent class, we can do so by super.foo(); we can also access parent elements by super keyword.
class parent {
String str="I am parent";
//method of parent Class
public void foo() {
System.out.println("Hello World " + str);
}
}
class child extends parent {
String str="I am child";
// different foo implementation in child Class
public void foo() {
System.out.println("Hello World "+str);
}
// calling the foo method of parent class
public void parentClassFoo(){
super.foo();
}
// changing the value of str in parent class and calling the foo method of parent class
public void parentClassFooStr(){
super.str="parent string changed";
super.foo();
}
}
public class Main{
public static void main(String args[]) {
child obj = new child();
obj.foo();
obj.parentClassFoo();
obj.parentClassFooStr();
}
}
Get highlighted text this way:
window.getSelection().toString()
and of course a special treatment for ie:
document.selection.createRange().htmlText
Map :
- It processes one row at a time , very similar to map() method of MapReduce.
- You return from the transformation after every row.
MapPartitions
- It processes the complete partition in one go.
- You can return from the function only once after processing the whole partition.
- All intermediate results needs to be held in memory till you process the whole partition.
- Provides you like setup() map() and cleanup() function of MapReduce

The Google Style Guide for HTML recommends omitting all optional tags.
That includes <html>
, <head>
, <body>
, <p>
and <li>
.
https://google.github.io/styleguide/htmlcssguide.html#Optional_Tags
For file size optimization and scannability purposes, consider omitting optional tags. The HTML5 specification defines what tags can be omitted.
(This approach may require a grace period to be established as a wider guideline as it’s significantly different from what web developers are typically taught. For consistency and simplicity reasons it’s best served omitting all optional tags, not just a selection.)
<!-- Not recommended --> <!DOCTYPE html> <html> <head> <title>Spending money, spending bytes</title> </head> <body> <p>Sic.</p> </body> </html> <!-- Recommended --> <!DOCTYPE html> <title>Saving money, saving bytes</title> <p>Qed.
The solution you want is the one proposed here:
https://stackoverflow.com/a/542802/50776
Basically, you do this:
cast(floor(cast(@dateVariable as float)) as datetime)
There is a function definition in the link which will allow you to consolidate the functionality and call it anywhere (instead of having to remember it) if you wish.
The proper way to install an MSI silently is via the msiexec.exe command line
as follows:
msiexec.exe /i c:\setup.msi /QN /L*V "C:\Temp\msilog.log"
Quick explanation:
/L*V "C:\Temp\msilog.log"= verbose logging
/QN = run completely silently
/i = run install sequence
There is a much more comprehensive answer here: Batch script to install MSI. This answer provides details on the msiexec.exe command line options and a description of how to find the "public properties" that you can set on the command line at install time. These properties are generally different for each MSI.
All of the answers so far, is missing one VERY important step, otherwise you will get "connection refused" when trying to connect.
Step 1: First enable Developer Options menu on your device, by navigating to the About menu on your device, then tapping the Build menu 5 times.
Step 2: Then go to the now visible Developer Options menu and enable USB debugging. Yes its a bit odd that you need this for Wifi debuging, but trust me, this is required.
Step 3:
adb connect [your devices ip address]
It should say that you're now connected
Another way is to tell the marshaller to always use a certain prefix
marshaller.setProperty("com.sun.xml.bind.namespacePrefixMapper", new NamespacePrefixMapper() {
@Override
public String getPreferredPrefix(String arg0, String arg1, boolean arg2) {
return "ns1";
}
});'
Here is another, very manual solution. You can define the size of the axis and paddings are considered accordingly (including legend and tickmarks). Hope it is of use to somebody.
Example (axes size are the same!):

,(1,0.5,0.5) #pink
,(0.5,0.5,0.5) #gray
,(0.5,0,0) #brown
,(1,0.5,0) #orange

The way I use is just a
Dictionary<string, List<string>>
This way you have a single key holding a list of strings.
Example:
List<string> value = new List<string>();
if (dictionary.Contains(key)) {
value = dictionary[key];
}
value.Add(newValue);
It can also be written this way
this.props.history.push(`${window.location.pathname}&page=${pageNumber}`)
Don't use while True and break statements. It's bad programming.
Imagine you come to debug someone else's code and you see a while True on line 1 and then have to trawl your way through another 200 lines of code with 15 break statements in it, having to read umpteen lines of code for each one to work out what actually causes it to get to the break. You'd want to kill them...a lot.
The condition that causes a while loop to stop iterating should always be clear from the while loop line of code itself without having to look elsewhere.
Phil has the "correct" solution, as it has a clear end condition right there in the while loop statement itself.
You can use the IGNORE
keyword too, example:
update IGNORE table set primary_field = 'value'...............
Setup a DocumentListener on nameField. When nameField is updated, update your label.

Install Inkscape and call it as command line:
${INKSCAPE_PATH} -z -f ${source_svg} -w ${width} -j -e ${dest_png}
You can also snap specific rectangular area only using parameter -j
, e.g. co-ordinate "0:125:451:217"
${INKSCAPE_PATH} -z -f ${source_svg} -w ${width} -j -a ${coordinates} -e ${dest_png}
If you want to show only one object in the SVG file, you can specify the parameter -i
with the object id that you have setup in the SVG. It hides everything else.
${INKSCAPE_PATH} -z -f ${source_svg} -w ${width} -i ${object} -j -a ${coordinates} -e ${dest_png}
public File getFilesDir ()
Returns the absolute path to the directory on the filesystem where files created with openFileOutput(String, int)
are stored.
public static File getExternalStorageDirectory ()
Return the primary external storage directory. This directory may not currently be accessible if it has been mounted by the user on their computer, has been removed from the device, or some other problem has happened. You can determine its current state with getExternalStorageState()
.
Note: don't be confused by the word "external" here. This directory can better be thought as media/shared storage. It is a filesystem that can hold a relatively large amount of data and that is shared across all applications (does not enforce permissions). Traditionally this is an SD card, but it may also be implemented as built-in storage in a device that is distinct from the protected internal storage and can be mounted as a filesystem on a computer.
On devices with multiple users (as described by UserManager), each user has their own isolated external storage. Applications only have access to the external storage for the user they're running as.
If you want to get your application path use getFilesDir()
which will give you path /data/data/your package/files
You can get the path using the Environment
var of your data/package
using the
getExternalFilesDir(Environment.getDataDirectory().getAbsolutePath()).getAbsolutePath();
which will return the path from the root directory of your external storage as
/storage/sdcard/Android/data/your pacakge/files/data
To access the external resources you have to provide the permission of WRITE_EXTERNAL_STORAGE
and READ_EXTERNAL_STORAGE
in your manifest.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

After the Version 2.3.0 the "spring-boot-strarter-test" (that included the NotNull/NotBlank/etc) is now "sprnig boot-strarter-validation"
Just change it from ....-test to ...-validation and it should work.
If not downgrading the version that you are using to 2.1.3 also will solve it.
You need to remove the /var/lib/mysql folder. Also, purge when you remove the packages (I'm told this helps).
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo rm -rf /var/lib/mysql
I was encountering similar issues. The second line got rid of my issues and allowed me to set up MySql from scratch. Hopefully it helps you too!
To fix the ugly look of a divider being too short when the content of one column is taller, add borders to all columns. Give every other column a negative margin to compensate for position differences.
For example, my three column classes:
.border-right {
border-right: 1px solid #ddd;
}
.borders {
border-left: 1px solid #ddd;
border-right: 1px solid #ddd;
margin: -1px;
}
.border-left {
border-left: 1px solid #ddd;
}
And the HTML:
<div class="col-sm-4 border-right">First</div>
<div class="col-sm-4 borders">Second</div>
<div class="col-sm-4 border-left">Third</div>
Make sure you use #ddd if you want the same color as Bootstrap's horizontal dividers.
You can also use the sqldf package in R.
Z <- sqldf('SELECT DISTINCT tablename.columnname FROM tablename ')
You will have to add it through code. Try this:
// 1.create UIView programmetically
var myView = UIView(frame: CGRectMake(100, 100, 100, 100))
// 2.add myView to UIView hierarchy
self.view.addSubview(myView)
// 3. add action to myView
let gesture = UITapGestureRecognizer(target: self, action: "someAction:")
// or for swift 2 +
let gestureSwift2AndHigher = UITapGestureRecognizer(target: self, action: #selector (self.someAction (_:)))
self.myView.addGestureRecognizer(gesture)
func someAction(sender:UITapGestureRecognizer){
// do other task
}
// or for Swift 3
func someAction(_ sender:UITapGestureRecognizer){
// do other task
}
// or for Swift 4
@objc func someAction(_ sender:UITapGestureRecognizer){
// do other task
}
// update for Swift UI
Text("Tap me!")
.tapAction {
print("Tapped!")
}
String.IsNullOrEmpty(string value)
returns true
if the string is null or empty.
For reference an empty string is represented by "" (two double quote characters)
String.IsNullOrWhitespace(string value)
returns true
if the string is null, empty, or contains only whitespace characters such as a space or tab.
To see what characters count as whitespace consult this link: http://msdn.microsoft.com/en-us/library/t809ektx.aspx
Kinda old subject but I had same question a few days ago and I came up with another idea (maybe someone will still find it usefull)
For example you can make a config.bat with different subjects (family, size, color, animals) and apply them individually in any order anywhere you want in your batch scripts:
@echo off
rem Empty the variable to be ready for label config_all
set config_all_selected=
rem Go to the label with the parameter you selected
goto :config_%1
REM This next line is just to go to end of file
REM in case that the parameter %1 is not set
goto :end
REM next label is to jump here and get all variables to be set
:config_all
set config_all_selected=1
:config_family
set mother=Mary
set father=John
set sister=Anna
rem This next line is to skip going to end if config_all label was selected as parameter
if not "%config_all_selected%"=="1" goto :end
:config_test
set "test_parameter_all=2nd set: The 'all' parameter WAS used before this echo"
if not "%config_all_selected%"=="1" goto :end
:config_size
set width=20
set height=40
if not "%config_all_selected%"=="1" goto :end
:config_color
set first_color=blue
set second_color=green
if not "%config_all_selected%"=="1" goto :end
:config_animals
set dog=Max
set cat=Miau
if not "%config_all_selected%"=="1" goto :end
:end
After that, you can use it anywhere by calling fully with 'call config.bat all' or calling only parts of it (see example bellow) The idea in here is that sometimes is more handy when you have the option not to call everything at once. Some variables maybe you don't want to be called yet so you can call them later.
Example test.bat
@echo off

Good day.
Escaping quotes in MSSQL is done by a double quote, so a ''
or a ""
will produce one escaped '
and "
, respectively.
hasOwnProperty
expects the property name as a string, so it would be shape1.hasOwnProperty("name")
Use count(*)
declare
cnt integer;
begin
SELECT count(*) INTO cnt
FROM people
WHERE person_id = my_person_id;
IF cnt > 0 THEN
-- Do something
END IF;
Edit (for the downvoter who didn't read the statement and others who might be doing something similar)
The solution is only effective because there is a where clause on a column (and the name of the column suggests that its the primary key - so the where clause is highly effective)
Because of that where
clause there is no need to use a LIMIT or something else to test the presence of a row that is identified by its primary key. It is an effective way to test this.
The values can be retrieved during the parsing:
var yahoo = [], j = `[{"name":"Lenovo Thinkpad 41A4298","website":"google"},_x000D_
{"name":"Lenovo Thinkpad 41A2222","website":"google"},_x000D_
{"name":"Lenovo Thinkpad 41Awww33","website":"yahoo"},_x000D_
{"name":"Lenovo Thinkpad 41A424448","website":"google"},_x000D_
{"name":"Lenovo Thinkpad 41A429rr8","website":"ebay"},_x000D_
{"name":"Lenovo Thinkpad 41A429ff8","website":"ebay"},_x000D_
{"name":"Lenovo Thinkpad 41A429ss8","website":"rediff"},_x000D_
{"name":"Lenovo Thinkpad 41A429sg8","website":"yahoo"}]`_x000D_
_x000D_
var data = JSON.parse(j, function(key, value) { _x000D_
if ( value.website === "yahoo" ) yahoo.push(value); _x000D_
return value; })_x000D_
_x000D_
console.log( yahoo )

try using

that worked for me.
No need for moment.js to parse the input since its format is the standard one :
var date = new Date('2014-02-27T10:00:00');
var formatted = moment(date).format('D MMMM YYYY');
I use when I do a big commit, above all when I remove more files from the repository.. after, the commits are faster
Here is a simpler way to migrate:
Start off with a sample Android Studio project. Open android studio and create a new project (or) just download a ‘sample’ studio project here: https://github.com/AppLozic/eclipse-to-android-studio-migration. Now, open the downloaded project in Android Studio by following the below instructions.
Import eclipse project modules into Android Studio. Select File -> New -> Import Module Image title
Next, select the path of the eclipse project and import the modules. In case, if you see the message “Failed to sync Gradle project,” then click on “Install Build Tools and sync project…”
Now, remove the sample project modules by following the below simple steps:
Open settings.gradle and remove “include ‘:app’” Right click on “app” module and “Delete” it. Now, what we have is the Eclipse project open in Android studio with the Gradle build.
Here are few other links which might help you:
http://developer.android.com/sdk/installing/migrate.html Source: http://www.applozic.com/blog/migrating-project-from-eclipse-to-studio/
You cannot use AppSettings static object for this. Try this
string appPath = System.IO.Path.GetDirectoryName(Reflection.Assembly.GetExecutingAssembly().Location);
string configFile = System.IO.Path.Combine(appPath, "App.config");
ExeConfigurationFileMap configFileMap = new ExeConfigurationFileMap();
configFileMap.ExeConfigFilename = configFile;
System.Configuration.Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configFileMap, ConfigurationUserLevel.None);
config.AppSettings.Settings["YourThing"].Value = "New Value";
config.Save();
Bootstrap 4
Create a responsive navbar sidebar "drawer" in Bootstrap 4?
Bootstrap horizontal menu collapse to sidemenu
Bootstrap 3
I think what you're looking for is generally known as an "off-canvas" layout. Here is the standard off-canvas example from the official Bootstrap docs: http://getbootstrap.com/examples/offcanvas/
The "official" example uses a right-side sidebar the toggle off and on separately from the top navbar menu. I also found these off-canvas variations that slide in from the left and may be closer to what you're looking for..

I am loading html pages from Documents and if they have the same name of css file UIWebView
it seem it does not throw the previous css rules. Maybe because they have the same URL or something.
I tried this:
NSURLCache *sharedCache = [[NSURLCache alloc] initWithMemoryCapacity:0 diskCapacity:0 diskPath:nil];
[NSURLCache setSharedURLCache:sharedCache];
[sharedCache release];
I tried this :
[[NSURLCache sharedURLCache] removeAllCachedResponses];
I am loading the initial page with:
NSURLRequest *appReq = [NSURLRequest requestWithURL:appURL cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:20.0];
It refuses to throw its cached data! Frustrating!
I am doing this inside a PhoneGap (Cordova) application. I have not tried it in isolated UIWebView.
Update1: I have found this.
Changing the html files, though seems very messy.
As String class methods (unix only):
class String

def red; "\e[31m#{self}\e[0m" end
def green; "\e[32m#{self}\e[0m" end
def brown; "\e[33m#{self}\e[0m" end
def blue; "\e[34m#{self}\e[0m" end
def magenta; "\e[35m#{self}\e[0m" end
def cyan; "\e[36m#{self}\e[0m" end

def underline; "\e[4m#{self}\e[24m" end
def blink; "\e[5m#{self}\e[25m" end
def reverse_color; "\e[7m#{self}\e[27m" end
end
and usage:
puts "I'm back green".bg_green
puts "I'm red and back cyan".red.bg_cyan
puts "I'm bold and green and backround red".bold.green.bg_red
on my console:
def no_colors
self.gsub /\e\[\d+m/, ""
end
removes formatting characters
puts "\e[31m" # set format (red foreground)
puts "\e[0m" # clear format
puts "green-#{"red".red}-green".green # will be green-red-normal, because of \e[0
Sometimes it is not eligible to set height to pixel values.
However, it is possible to show vertical scrollbar through setting height of div to 100%
and overflow
to auto
.
Let me show an example:
<div id="content" style="height: 100%; overflow: auto">
<p>some text</p>
<ul>
<li>text</li>
.....
<li>text</li>
</div>
// dict is Dictionary<string, Foo>
Foo[] foos = new Foo[dict.Count];
dict.Values.CopyTo(foos, 0);
// or in C# 3.0:
var foos = dict.Values.ToArray();

Test the return value of grep:
./somecommand | grep 'string' &> /dev/null
if [ $? == 0 ]; then
echo "matched"
fi
which is done idiomatically like so:
if ./somecommand | grep -q 'string'; then
echo "matched"
fi
and also:
./somecommand | grep -q 'string' && echo 'matched'
The danger in using a backslash to end a line is that if whitespace is added after the backslash (which, of course, is very hard to see), the backslash is no longer doing what you thought it was.
See Python Idioms and Anti-Idioms (for Python 2 or Python 3) for more.
I had to edit ~/.subversion/servers
. I set store-plaintext-passwords = yes
(was no previously). That did the trick. It might be considered insecure though.
Probably the exact details of em.flush()
are implementation-dependent.
In general anyway, JPA providers like Hibernate can cache the SQL instructions they are supposed to send to the database, often until you actually commit the transaction.
For example, you call em.persist()
, Hibernate remembers it has to make a database INSERT, but does not actually execute the instruction until you commit the transaction. Afaik, this is mainly done for performance reasons.
In some cases anyway you want the SQL instructions to be executed immediately; generally when you need the result of some side effects, like an autogenerated key, or a database trigger.
What em.flush()
does is to empty the internal SQL instructions cache, and execute it immediately to the database.
Bottom line: no harm is done, only you could have a (minor) performance hit since you are overriding the JPA provider decisions as regards the best timing to send SQL instructions to the database.
From C# 6:
var dateTimeUtcAsString = $"{DateTime.UtcNow:o}";
The result will be: "2019-01-15T11:46:33.2752667Z"
Migrating from Glyphicons to Font Awesome is quite easy.
Include a reference to Font Awesome (either locally, or use the CDN).
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet">
Then run a search and replace where you search for glyphicon glyphicon-
and replace it with fa fa-
, and also change the enclosing element from <span
to <i
. Most of the CSS class names are the same. Some have changed though, so you have to manually fix those.
I added this to my .bashrc
function npmv {
case $# in # number of arguments passed
0) v="$(npm -v)" ; #store output from npm -v in variable
echo "NPM version is: $v"; #can't use single quotes
#${v} would also work
;;
1) s="$(npm list --depth=0 $1 | grep $1 | cut -d @ -f 2)";
echo "$s";
;;
2) case "$2" in # second argument
g) #global|#Syntax to compare bash string to literal
s="$(npm list --depth=0 -g $1 | grep $1 | cut -d @ -f 2)";
echo "$s";
;;
l) #latest
npm view $1 version; #npm info $1 version does same thing
;;
*) echo 'Invalid arguments';
;;
esac;
;;
*) echo 'Invalid arguments';
;;
esac;
}
export -f npmv
Now all I have to do is type:
NPM version is: 4.2.0
0.8.08
0.8.09
0.8.10
Note -d on cut command means delimit by, followed by @, then f means field the 2 means second field since there will be one either side of the @ symbol.
using, for example, "%-d" is not portable even between different versions of the same OS. A better solution would be to extract the date components individually, and choose between date specific formatting operators and date attribute access for each component.
e = datetime.date(2014, 1, 6)
"{date:%A} {date.day} {date:%B}{date.year}".format(date=e)
For me, it worked to remove the files that are throwing errors from the folder .git/refs/remotes/origin/
.
in your dispatcher servlet context xml, you have to add a propertie
"<property name="contentType" value="text/html;charset=UTF-8" />"
on your viewResolver bean.
we are using freemarker for views.
it looks something like this:
<bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
...
<property name="contentType" value="text/html;charset=UTF-8" />

I'm going to be brave and throw my hat into the ring on this one (ancient as it is), see how many downvotes I can collect.
Here is my attempt, which does seem to work everywhere I have tested it (Chrome20, IE8 and FF14):
(function() {
if (top == self) {
return;
}
setInterval(function() {
top.location.replace(document.location);
setTimeout(function() {
var xhr = new XMLHttpRequest();
xhr.open(
'get',
'http://mysite.tld/page-that-takes-a-while-to-load',
false
);
xhr.send(null);
}, 0);
}, 1);
}());
I placed this code in the <head>
and called it from the end of the <body>
to ensure my page is rendered before it starts arguing with the malicious code, don't know if this is the best approach, YMMV.
How does it work?
...I hear you ask - well the honest answer is, I don't really know. It took a lot of fudging about to make it work everywhere I was testing, and the exact effect that it has varies slightly depending on where you run it.
Here is the thinking behind it:
For my http://mysite.tld/page-that-takes-a-while-to-load
(the target of the XHR) I used a PHP script that looks like this:
<?php sleep(5);
What happens?
Can't you avoid the wait time in Chrome and Firefox?
Apparently not. At first I pointed the XHR to a URL that would return a 404 - this didn't work in Firefox. Then I tried the sleep(5);
approach that I eventually landed on for this answer, then I started playing around with the sleep length in various ways. I could find no real pattern to the behaviour, but I did find that if it is too short, specifically Firefox will not play ball (Chrome and IE seem to be fairly well behaved). I don't know what the definition of "too short" is in real terms, but 5 seconds seems to work every time.
If any passing Javascript ninjas want to explain a little better what's going on, why this is (probably) wrong, unreliable, the worst code they've ever seen etc I'll happily listen.
Based on the accepted response by tiago, here is a small generic function that exports a numpy array to an image having the same resolution as the array:
import matplotlib.pyplot as plt
import numpy as np
def export_figure_matplotlib(arr, f_name, dpi=200, resize_fact=1, plt_show=False):
"""
Export array as figure in original resolution
:param arr: array of image to save in original resolution
:param f_name: name of file where to save figure
:param resize_fact: resize facter wrt shape of arr, in (0, np.infty)
:param dpi: dpi of your screen
:param plt_show: show plot or not
"""
fig = plt.figure(frameon=False)
fig.set_size_inches(arr.shape[1]/dpi, arr.shape[0]/dpi)
ax = plt.Axes(fig, [0., 0., 1., 1.])
ax.set_axis_off()
fig.add_axes(ax)
ax.imshow(arr)
plt.savefig(f_name, dpi=(dpi * resize_fact))
if plt_show:
plt.show()
else:
plt.close()
As said in the previous reply by tiago, the screen DPI needs to be found first, which can be done here for instance: http://dpi.lv
I've added an additional argument resize_fact
in the function which which you can export the image to 50% (0.5) of the original resolution, for instance.
If you are using Typescript 3.7 or newer you can now also do:
const data = change?.after?.data();
if(!data) {
console.error('No data here!');
return null
}
const maxLen = 100;
const msgLen = data.messages.length;
const charLen = JSON.stringify(data).length;
const batch = db.batch();
if (charLen >= 10000 || msgLen >= maxLen) {
// Always delete at least 1 message
const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
data.messages.splice(0, deleteCount);
const ref = db.collection("chats").doc(change.after.id);
batch.set(ref, data, { merge: true });
return batch.commit();
} else {
return null;
}
Typescript is saying that change
or data
is possibly undefined
(depending on what onUpdate
returns).
So you should wrap it in a null/undefined check:
if(change && change.after && change.after.data){
const data = change.after.data();
const maxLen = 100;
const msgLen = data.messages.length;
const charLen = JSON.stringify(data).length;
const batch = db.batch();
if (charLen >= 10000 || msgLen >= maxLen) {
// Always delete at least 1 message
const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
data.messages.splice(0, deleteCount);
const ref = db.collection("chats").doc(change.after.id);
batch.set(ref, data, { merge: true });
return batch.commit();
} else {
return null;
}
}
If you are 100% sure that your object
is always defined then you can put this:
const data = change.after!.data();
size_t lf = strlen(first);
size_t ls = strlen(second);
char *both = (char*) malloc((lf + ls + 2) * sizeof(char));
strcpy(both, first);
both[lf] = ' ';
strcpy(&both[lf+1], second);
It's not a file association problem since you can launch the application correctly through command line.
The problem is when you double click on an associated file the application starts and runs with the file's path as base execution path. Any relative path will be computed from the file path and everything you try to load will probably be missing.
Nothing happens, even if you surround all of your entry point code with try/catch(Exception) because java s throwing Throwables and not Exceptions: to fix this in your java entry point surround the content of the main method with a try/catch(Throwable) (base class for Exception and Error) and debug.

I know that this question is accepted and has a bit of age but this might be helpful for some people who still find it relevant. Although the outcome is not a full RESTful API the API Builder mini lib for PHP allows you to easily transform MySQL databases into web accessible JSON APIs.

You need to go into the developer console and set
http://localhost:8080/WEBAPP/youtube-callback.html
as your callback URL.
This video is slightly outdated, as it shows the older Developer Console instead of the new one, however, the concepts should still apply. You need to find your project in the developer console and register a callback URL.
next() and nextLine() methods are associated with Scanner and is used for getting String inputs. Their differences are...
next() can read the input only till the space. It can't read two words separated by space. Also, next() places the cursor in the same line after reading the input.
nextLine() reads input including space between the words (that is, it reads till the end of line \n). Once the input is read, nextLine() positions the cursor in the next line.
Read article :Difference between next() and nextLine()
Replace your while loop with :
while(r.hasNext()) {
scan = r.next();
System.out.println(scan);
if(scan.length()==0) {continue;}
//treatment
}
Using hasNext()
and next()
methods will resolve the issue.
Presumably, you want to convert values before the decimal place to an integer. If so, use case
and check for the right format:
SELECT (case when varcharcol not like '%.%' then cast(varcharcol as int)
else cast(left(varcharcol, chardindex('.', varcharcol) - 1) as int)
end) IntVal
FROM MyTable;
As of Ruby 2.6.0, the numeric cast-methods have an optional exception
-argument [1]. This enables us to use the built-in methods without using exceptions as control flow:
Float('x') # => ArgumentError (invalid value for Float(): "x")
Float('x', exception: false) # => nil
Therefore, you don't have to define your own method, but can directly check variables like e.g.
if Float(my_var, exception: false)
# do something if my_var is a float
end
On older notebooks with integrated video Swing app starts and works much faster than JavaFX app. As for development, I'd recommend switch to Scala - comparable Scala Swing app contains 2..3 times less code than Java. As for Swing vs SWT: Netbeans GUI considerably faster than Eclipse...
You could return Enumerable.Empty<T>()

if you are trying to use jquery in your electron app before adding jquery you should add it to your modules:

Have a look at Knockout-Validation which cleanly setups and uses what's described in the knockout documentation. Under: Live Example 1: Forcing input to be numeric
You can see it live in Fiddle
UPDATE: the fiddle has been updated to use the latest KO 2.0.3 and ko.validation 1.0.2 using the cloudfare CDN urls
To setup ko.validation:
ko.validation.rules.pattern.message = 'Invalid.';
ko.validation.configure({
registerExtenders: true,
messagesOnModified: true,
insertMessages: true,
parseInputAttributes: true,
messageTemplate: null
});
To setup validation rules, use extenders. For instance:
var viewModel = {
firstName: ko.observable().extend({ minLength: 2, maxLength: 10 }),
lastName: ko.observable().extend({ required: true }),
emailAddress: ko.observable().extend({ // custom message
required: { message: 'Please supply your email address.' }
})
};
There is a really cool solution from Danny Markov for that. It uses navigator.getUserMedia method and should work in modern browsers. I have tested it successfully with Firefox and Chrome. IE didn't work:

I found it is better to use the command Serial.readString()
to replace the Serial.read()
to obtain the continuous I/O for Arduino.
myInt.ToString("D4");
Here is a solution I wrote using the builder tactic:
#include <string>
#include <sstream>
using std::string;
using std::stringstream;
string stringReplace (const string& source,
const string& toReplace,
const string& replaceWith)
{
size_t pos = 0;
size_t cursor = 0;
int repLen = toReplace.length();
stringstream builder;
do
{
pos = source.find(toReplace, cursor);
if (string::npos != pos)
{
//copy up to the match, then append the replacement
builder << source.substr(cursor, pos - cursor);
builder << replaceWith;
// skip past the match
cursor = pos + repLen;
}
}
while (string::npos != pos);
//copy the remainder
builder << source.substr(cursor);
return (builder.str());
}
Tests:
void addTestResult (const string&& testId, bool pass)
{
...
}
void testStringReplace()
{
string source = "123456789012345678901234567890";

bool pass = (0 == result.compare(expected));
addTestResult("567", pass);
source = "123456789012345678901234567890";
toReplace = "123";
replaceWith = "-";
result = stringReplace(source, toReplace, replaceWith);
expected = "-4567890-4567890-4567890";

For me it caused by installing react-native-vector-icons and linking by running the react-native link react-native-vector-icons
command.
I just unlinked the react-native-vector-icons by following commands
react-native unlink react-native-vector-icons
cd ios
pod install
cd ..
react-native run-ios
As I already installed an other icon library.
I was trying to install pyautogui and followed instructions from the first answer but was unsuccessful. The difference for me was running pip install pillow
and then running pip install pyautogui
I don't know what this means, but I hope this helps some people out.
Add below event to DateTimePicker
Private Sub DateTimePicker1_KeyPress(sender As Object, e As KeyPressEventArgs) Handles DateTimePicker1.KeyPress
e.Handled = True
End Sub
Even faster than a bad query:
SELECT count((1)) as `ct` FROM INFORMATION_SCHEMA.TABLES where table_schema ='yourdatabasename' and table_name='yourtablename';
This way you can just retrieve one field and one value. .016 seconds for my slower system.
I had a same problem and i could fixed it! you should add C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib\x64 for 64 bit system / C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib for 32 bit system in property manager-> Linker-> General->Additional library Directories
maybe it can solve the problem of somebody in the future!
imageView.setLayoutParams
(new ViewGroup.MarginLayoutParams
(width, ViewGroup.LayoutParams.MATCH_PARENT));
The Type of layout params depends on the parent view group. If you put the wrong one it will cause exception.
If you are in a directory where only root have access to write in system. Then you can directly use wget www.example.com/wget-test
using a standard user account. So it will hit the url but because of having no write permission file won't be saved..
This method is working fine for me as i am using this method for a cronjob.
Thanks.

Undefined reference to vtable may occur due to the following situation also. Just try this:
Class A Contains:
virtual void functionA(parameters)=0;
virtual void functionB(parameters);
Class B Contains:
Class C Contains: Now you're writing a Class C in which you are going to derive it from Class A.
Now if you try to compile you will get Undefined reference to vtable for Class C as error.
Reason:
functionA
is defined as pure virtual and its definition is provided in Class B.
functionB
is defined as virtual (NOT PURE VIRTUAL) so it tries to find its definition in Class A itself but you provided its definition in Class B.
Solution:
virtual void functionB(parameters) =0;
(This works it is Tested)On MAC AMPPS, I updated the php-5.5.ini with the following and now it works.
allow_url_include = On
extension=openssl.so
There's a pretty nice interface for this in processing, which is kind of a pidgin java designed for graphics. It gets used in some image recognition work, such as that link.
Depending on what you need out of it, you might be able to load the video library that's used there in java, or if you're just playing around with it you might be able to get by using processing itself.
Still at 2014 seamless iframe is not fully supported by all of the major browsers, so you should look for an alternative solution.
By January 2014 seamless iframe is still not supported for Firefox neither IE 11, and it's supported by Chrome, Safari and Opera (the webkit version)
If you wanna check this and more supported options in detail, the HTML5 test site would be a good option:
http://html5test.com/results/desktop.html
You can check different platforms, at the score section you can click every browser and see what's supported and what's not.
If you want this to work with string enums, you need to use Object.values(ENUM).includes(ENUM.value)
because string enums are not reverse mapped, according to https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-4.html:
Enum Vehicle {
Car = 'car',
Bike = 'bike',
Truck = 'truck'
}
becomes:
{
Car: 'car',
Bike: 'bike',
Truck: 'truck'
}
So you just need to do:
if (Object.values(Vehicle).includes('car')) {
// Do stuff here
}
If you get an error for: Property 'values' does not exist on type 'ObjectConstructor'
, then you are not targeting ES2017. You can either use this tsconfig.json config:
"compilerOptions": {
"lib": ["es2017"]
}
Or you can just do an any cast:
if ((<any>Object).values(Vehicle).includes('car')) {
// Do stuff here
}
In your app.config
, change your appsetting to:
<applicationSettings>
<WpfApplication1.Properties.Settings>
<setting name="appsetting" serializeAs="String">
<value>c:\testdata.xml</value>
</setting>
</WpfApplication1.Properties.Settings>
</applicationSettings>
Then, in the code-behind:
string xmlDataDirectory = WpfApplication1.Properties.Settings.Default.appsetting.ToString()
$(window).load is an event that fires when the DOM and all the content (everything) on the page is fully loaded like CSS, images and frames. One best example is if we want to get the actual image size or to get the details of anything we use it.
$(document).ready() indicates that code in it need to be executed once the DOM got loaded and ready to be manipulated by script. It won't wait for the images to load for executing the jQuery script.
<script type = "text/javascript">
//$(window).load was deprecated in 1.8, and removed in jquery 3.0
// $(window).load(function() {
// alert("$(window).load fired");
// });
$(document).ready(function() {
alert("$(document).ready fired");
});
</script>
$(window).load fired after the $(document).ready().
$(window).load was deprecated in 1.8, and removed in jquery 3.0
The most compact version:
<input type="submit" onclick="return confirm('Are you sure?')" />
The key thing to note is the return
-
Because there are many ways to skin a cat, here is another alternate method:
HTML:
<input type="submit" onclick="clicked(event)" />
Javascript:
<script>
function clicked(e)
{
if(!confirm('Are you sure?')) {
e.preventDefault();
}
}
</script>
Assuming one has installed a JDK in /opt/java/jdk1.8.0_144
then:
Install the alternative for javac
$ sudo update-alternatives --install /usr/bin/javac javac /opt/java/jdk1.8.0_144/bin/javac 1
Check / update the alternatives config:
$ sudo update-alternatives --config javac
If there is only a single alternative for javac
you will get a message saying so, otherwise select the option for the new JDK.
To check everything is setup correctly then:
$ which javac
/usr/bin/javac
$ ls -l /usr/bin/javac
lrwxrwxrwx 1 root root 23 Sep 4 17:10 /usr/bin/javac -> /etc/alternatives/javac
$ ls -l /etc/alternatives/javac
lrwxrwxrwx 1 root root 32 Sep 4 17:10 /etc/alternatives/javac -> /opt/java/jdk1.8.0_144/bin/javac
And finally
$ javac -version
javac 1.8.0_144
Repeat for java, keytool, jar, etc as needed.
Doing the expicit casting to the "int" solves the problem in my case. I had the same issue. So:
int count = (int)[myColors count];
Im using a custom image instead of the default title text to the right of my apps logo. This is set up programatically like
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setDisplayUseLogoEnabled(true);
actionBar.setCustomView(R.layout.include_ab_txt_logo);
actionBar.setDisplayShowCustomEnabled(true);
The issues with the above answers for me are @Cliffus's suggestion does not work for me due to the issues others have outlined in the comments and while @dushyanth programatic padding setting may have worked in the past I would think that the fact that the spacing is now set using android:layout_marginEnd="8dip"
since API 17 manually setting the padding should have no effect. See the link he posted to git to verify its current state.
A simple solution for me is to set a negative margin on my custom view in the actionBar, like so android:layout_marginLeft="-14dp"
. A quick test shows it works for me on 2.3.3 and 4.3 using ActionBarCompat
Hope this helps someone!
If you're using the command console to compile the servlet, then you should include Tomcat's /lib/servlet-api.jar
in the compile classpath.
javac -cp .:/path/to/tomcat/lib/servlet-api.jar com/example/MyServlet.java
(use ;
instead of :
as path separator in Windows)
If you're using an IDE, then you should integrate Tomcat in the IDE and reference it as target runtime in the project. If you're using Eclipse as IDE, see also this for more detail: How do I import the javax.servlet API in my Eclipse project?
\d
is a digit (a character in the range 0-9), and +
means 1 or more times. So, \d+
is 1 or more digits.
This is about as simple as regular expressions get. You should try reading up on regular expressions a little bit more. Google has a lot of results for regular expression tutorial, for instance. Or you could try using a tool like the free Regex Coach that will let you enter a regular expression and sample text, then indicate what (if anything) matches the regex.
Use the id
of the element to do the same.
document.getElementById(id).style.visibility = 'hidden';
Your JavaScript would have to be defined within a PHP-parsed file.
For example, in index.php you could place
<?php
$time = time();
?>
<script>
document.write(<?php echo $time; ?>);
</script>
yes, using and
, like:
@media screen and (max-width: 800px),
screen and (max-height: 600px) {
...
}
center-block
is bad idea as it covers a portion on your screen and you cannot click on your fields or buttons.
col-md-offset-?
is better option.
Use col-md-offset-3
is better option if class is col-sm-6
. Just change the number to center your block.
I use the len
function. It's much faster than empty
. len(df.index)
is even faster.
import pandas as pd
import numpy as np
df = pd.DataFrame(np.random.randn(10000, 4), columns=list('ABCD'))
def empty(df):
return df.empty
def lenz(df):
return len(df) == 0
def lenzi(df):
return len(df.index) == 0
'''
%timeit empty(df)
%timeit lenz(df)
%timeit lenzi(df)
10000 loops, best of 3: 13.9 µs per loop
100000 loops, best of 3: 2.34 µs per loop
1000000 loops, best of 3: 695 ns per loop
len on index seems to be faster
'''
It's not so much the prime numbers themselves that are important, but the algorithms that work with primes. In particular, finding the factors of a number (any number).
As you know, any number has at least two factors. Prime numbers have the unique property in that they have exactly two factors: 1 and themselves.
The reason factoring is so important is mathematicians and computer scientists don't know how to factor a number without simply trying every possible combination. That is, first try dividing by 2, then by 3, then by 4, and so forth. If you try to factor a prime number--especially a very large one--you'll have to try (essentially) every possible number between 2 and that large prime number. Even on the fastest computers, it will take years (even centuries) to factor the kinds of prime numbers used in cryptography.
It is the fact that we don't know how to efficiently factor a large number that gives cryptographic algorithms their strength. If, one day, someone figures out how to do it, all the cryptographic algorithms we currently use will become obsolete. This remains an open area of research.
There is a useful tool written using perl called Maatkit. It has several database comparison and syncing tools among other things.
By the way it is written, clean rule is invoked only if it is explicitly called:
make clean
I think it is better, than make clean every time. If you want to do this by your way, try this:
CXX = g++ -O2 -Wall all: clean code1 code2 code1: code1.cc utilities.cc $(CXX) $^ -o $@ code2: code2.cc utilities.cc $(CXX) $^ -o $@ clean: rm ... echo Clean done
You can use:
$redirectURL = curl_getinfo($ch,CURLINFO_REDIRECT_URL);
We can calculate using mid point of line formula,
centre (x,y) = new Point((boundRect.tl().x+boundRect.br().x)/2,(boundRect.tl().y+boundRect.br().y)/2)
You can also do like this,
<form method='POST'>
{{form1.as_p}}
<button type="submit" name="btnform1">Save Changes</button>
</form>
<form method='POST'>
{{form2.as_p}}
<button type="submit" name="btnform2">Save Changes</button>
</form>
CODE
if request.method=='POST' and 'btnform1' in request.POST:
do something...
if request.method=='POST' and 'btnform2' in request.POST:
do something...

I hope it will be helpfully for other programmers.
MichaelMocko Answered is great,
but I want to add a few things which I had to figure out
(string first, string middle, string last) LookupName(long id)
above Line will give you compile-time error if you are using .net framework < 4.7
So if you have a project that is using .net framework < 4.7 and still you want to use ValueTuple than workAround would be installing this NuGet package
Update:
Example of returning Named tuple from a method and using it
public static (string extension, string fileName) GetFile()
{
return ("png", "test");
}
Using it
var (extension, fileName) = GetFile();
Console.WriteLine(extension);
Console.WriteLine(fileName);
Timezone/daylight savings aware date increment for JavaScript dates:
function nextDay(date) {
const sign = v => (v < 0 ? -1 : +1);
const result = new Date(date.getTime());
result.setDate(result.getDate() + 1);
const offset = result.getTimezoneOffset();
return new Date(result.getTime() + sign(offset) * offset * 60 * 1000);
}
I was too facing similar issue and here I found another solution for it.
I have just started Eclipse Luna and not developed/deployed any project yet. I tried adding Tomcat v7.0 Server
and got same error.
In order to resolve the issue I went to Server Perspective
(it's actually server tab next to the console tab located below Project
code). Double click on Server which is added to Eclipse. It will open up Overview page. Look for Server Location and select Use workspace metadata(does not modify Tomcat location). Now restart the Server and error will go away.
Server > (double click) Tomcat v7.0 Server at localhost > (Overview page) Server Location > Select -- Use workspace metadata(does not modify Tomcat location).

One can think of Grep as a restricted Sed, or of Sed as a generalized Grep. In this case, Sed is one good, lightweight tool that does what you want -- though, of course, there exist several other reasonable ways to do it, too.
In your home folder /.android/avd//config.ini add the line hw.keyboard=yes

I'm coming from a SQL Server background also and spent the past 2 weeks figuring out how to run scripts like this in IBM Data Studio. Hope it helps.
CREATE VARIABLE v_lookupid INTEGER DEFAULT (4815162342); --where 4815162342 is your variable data
SELECT * FROM DB1.PERSON WHERE PERSON_ID = v_lookupid;
SELECT * FROM DB1.PERSON_DATA WHERE PERSON_ID = v_lookupid;
SELECT * FROM DB1.PERSON_HIST WHERE PERSON_ID = v_lookupid;
DROP VARIABLE v_lookupid;
From the Android documentation:
The
CookieSyncManager
is used to synchronize the browser cookie store between RAM and permanent storage. To get the best performance, browser cookies are saved in RAM. A separate thread saves the cookies between, driven by a timer.To use the
CookieSyncManager
, the host application has to call the following when the application starts:CookieSyncManager.createInstance(context)
To set up for sync, the host application has to call
CookieSyncManager.getInstance().startSync()
in Activity.onResume(), and call
CookieSyncManager.getInstance().stopSync()
in Activity.onPause().
To get instant sync instead of waiting for the timer to trigger, the host can call
CookieSyncManager.getInstance().sync()
The sync interval is 5 minutes, so you will want to force syncs manually anyway, for instance in onPageFinished(WebView, String). Note that even sync() happens asynchronously, so don't do it just as your activity is shutting down.
Finally something like this should work:
// use cookies to remember a logged in status
CookieSyncManager.createInstance(this);
CookieSyncManager.getInstance().startSync();
WebView webview = new WebView(this);
webview.getSettings().setJavaScriptEnabled(true);
setContentView(webview);
webview.loadUrl([MY URL]);
For the record, on Debian 9 Stretch (systemd
), I had to install the package systemd-coredump
. Afterwards, core dumps were generated in the folder /var/lib/systemd/coredump
.
Furthermore, these coredumps are compressed in the lz4
format. To decompress, you can use the package liblz4-tool
like this: lz4 -d FILE
.
To be able to debug the decompressed coredump using gdb
, I also had to rename the utterly long filename into something shorter...
There's a good answer here:
function toTitleCase(str) {
return str.replace(/\w\S*/g, function(txt){
return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase();
});
}
or in ES6:
var text = "foo bar loo zoo moo";
text = text.toLowerCase()
.split(' ')
.map((s) => s.charAt(0).toUpperCase() + s.substring(1))
.join(' ');
Simple solution:
static void Main()
{
List<string> myList = new List<string> { "Jason", "Bob", "Frank", "Bob" };
myList.RemoveAll(x => x == "Bob");
foreach (string s in myList)
{
//
}
}
Use
System.getProperty("java.class.path")
see http://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html
You can also split it into it's elements easily
String classpath = System.getProperty("java.class.path");
String[] classpathEntries = classpath.split(File.pathSeparator);
This class was deprecated in API level 26. ProgressDialog is a modal dialog, which prevents the user from interacting with the app. Instead of using this class, you should use a progress indicator like ProgressBar, which can be embedded in your app's UI. Alternatively, you can use a notification to inform the user of the task's progress. link
It's deprecated at Android O
because of Google
new UI standard
The Microsoft AJAX library will accomplish this. You could also create your own solution that involves using AJAX to call your own aspx (as basically) script files to run .NET functions.
This is the library called AjaxPro which was written an MVP named Michael Schwarz. This was library was not written by Microsoft.
I have used AjaxPro extensively, and it is a very nice library, that I would recommend for simple callbacks to the server. It does function well with the Microsoft version of Ajax with no issues. However, I would note, with how easy Microsoft has made Ajax, I would only use it if really necessary. It takes a lot of JavaScript to do some really complicated functionality that you get from Microsoft by just dropping it into an update panel.
simply use the form_validation class of codeigniter:
strip_image_tags($str).
$this->load->library('form_validation');
$this->form_validation->set_rules('nombre_campo', 'label', 'strip_image_tags');
background-color: rgba(255, 0, 0, 0.5); as mentioned above is the best answer simply put. To say use CSS 3, even in 2013, is not simple because the level of support from various browsers changes with every iteration.
While background-color
is supported by all major browsers (not new to CSS 3) [1] the alpha transparency can be tricky, especially with Internet Explorer prior to version 9 and with border color on Safari prior to version 5.1. [2]
Using something like Compass or SASS can really help production and cross platform compatibility.

Is "Id" indexed? If not, that's an important thing to do (I suspect it is already indexed).
Also, do you need to return ALL columns? You may be able to get a substantial improvement in speed if you only actually need a smaller subset of columns which can be FULLY catered for by the index on the ID column - e.g. if you have a NONCLUSTERED index on the Id column, with no other fields included in the index, then it would have to do a lookup on the clustered index to actually get the rest of the columns to return and that could be making up a lot of the cost of the query. If it's a CLUSTERED index, or a NONCLUSTERED index that includes all the other fields you want to return in the query, then you should be fine.
If you are looking for PERFORMANCE, give where condition inside the db link query. Otherwise it fetch all data from the foreign table and apply the where condition.
INSERT INTO tblA (id,time)
SELECT id, time FROM dblink('dbname=dbname port=5432 host=10.10.90.190 user=postgresuser password=pass123',
'select id, time from tblB where time>'''||1000||'''')
AS t1(id integer, time integer)
to also check blank string, I suggest following
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<c:if test="${empty fn:trim(var1)}">
</c:if>
It also handles nulls
What about the following snippet?
require 'json'
value = '{"val":"test","val1":"test1","val2":"test2"}'
puts JSON.parse(value) # => {"val"=>"test","val1"=>"test1","val2"=>"test2"}
inspect.getargspec() to meet your needs
from inspect import getargspec
def func(a, b):
pass
print len(getargspec(func).args)
did you try 'git add .' . will it all the changes? (you can remove unnecessary added files by git reset HEAD )
This could be because you are missing an import.
Example:
ERROR in src/app/products/product-list.component.ts:15:15 - error TS2304: Cannot find name 'IProduct'.
Make sure you are adding the import at the top of the file:
import { IProduct } from './product';
...
export class ProductListComponent {
pageTitle: string = 'product list!';
imageWidth: number = 50;
imageMargin: number = 2;
showImage: boolean = false;
listFilter: string = 'cart';
products: IProduct[] = ... //cannot find name error
Do this for your database. I have the same issue - it works fine in one database but when I copy this database to another using SSIS Import (not the usual restore), this issue happens to most of my stored procedures. So after googling some more, I found the blog of Pinal Dave (which btw, I encountered most of his post and did help me a lot so thanks Pinal Dave).
I execute the below query on my database and it corrected my issue:
EXEC sp_MSforeachtable @command1="print '?' DBCC DBREINDEX ('?', ' ', 80)"
GO
EXEC sp_updatestats
GO
Hope this helps. Just passing the help from others that helped me.
Use:
npm run test -- test-name
This will only work if your test specification name is unique.
The code above would reference a file with this name: test-name.component.spec.ts

If you wish to use jQuery CDN other than Google hosted jQuery library, you might consider using this and ensures uses the latest version of jQuery:
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
We were trying to avoid using the IE specific
$window[0].document.body.clientHeight
And found that the following jQuery will not consistently yield the same value but eventually does at some point in our page load scenario which worked for us and maintained cross-browser support:
$(document).height()
To jump between words and start/end of lines in iTerm2 pick one of the two solutions below.
If you don't want to use the "Natural Text Editing" preset mentioned above, you can map the keys you need manually:
[+]
iconMove cursor one word left
0x1b 0x62
Move cursor one word right
0x1b 0x66
Move cursor to beginning of line
0x01
Move cursor to end of line
0x05
Delete word
0x1b 0x08
Delete line
0x15
Undo
0x1f
Don't forget to remove the previous bindings:
it works for me !!
in mysql table
DATETIME
in entity:
private Date startDate;
in process:
objectEntity.setStartDate(new Date());
in preparedStatement:
pstm.setDate(9, new java.sql.Date(objEntity.getStartDate().getTime()));
In CakePHP 1.3, use 'default'=>value
to select the default value in a select input:
$this->Form->input('Leaf.id', array('type'=>'select', 'label'=>'Leaf', 'options'=>$leafs, 'default'=>'3'));
You have an error in your syntax here:
this._possessions = new Thing[100]();
This doesn't create an "array of things". To create an array of things, you can simply use the array literal expression:
this._possessions = [];
Of the array constructor if you want to set the length:
this._possessions = new Array(100);
I have created a brief working example you can try in the playground.
module Entities {
class Thing {
}
export class Person {
private _name: string;
private _possessions: Thing[];
private _mostPrecious: Thing;
constructor (name: string) {
this._name = name;
this._possessions = [];
this._possessions.push(new Thing())
this._possessions[100] = new Thing();
}
}
}
i think token must include all the needed information encoded inside it, which makes authentication by validating the token and decoding the info https://www.oauth.com/oauth2-servers/access-tokens/self-encoded-access-tokens/
In this case, you can used:
Page Object:
waitForURLContain(urlExpected: string, timeout: number) {
try {
const condition = browser.ExpectedConditions;
browser.wait(condition.urlContains(urlExpected), timeout);
} catch (e) {
console.error('URL not contain text.', e);
};
}
Page Test:
page.waitForURLContain('abc#/efg', 30000);
Global variables are not extern
nor static
by default on C and C++.
When you declare a variable as static
, you are restricting it to the current source file. If you declare it as extern
, you are saying that the variable exists, but are defined somewhere else, and if you don't have it defined elsewhere (without the extern
keyword) you will get a link error (symbol not found).
Your code will break when you have more source files including that header, on link time you will have multiple references to varGlobal
. If you declare it as static
, then it will work with multiple sources (I mean, it will compile and link), but each source will have its own varGlobal
.
What you can do in C++, that you can't in C, is to declare the variable as const
on the header, like this:
const int varGlobal = 7;
And include in multiple sources, without breaking things at link time. The idea is to replace the old C style #define
for constants.
If you need a global variable visible on multiple sources and not const
, declare it as extern
on the header, and then define it, this time without the extern keyword, on a source file:
Header included by multiple files:
extern int varGlobal;
In one of your source files:
int varGlobal = 7;
ProxyPass /node http://localhost:8000/
It formats the string as two uppercase hexadecimal characters.
In more depth, the argument "X2"
is a "format string" that tells the ToString()
method how it should format the string. In this case, "X2" indicates the string should be formatted in Hexadecimal.
byte.ToString()
without any arguments returns the number in its natural decimal representation, with no padding.
Microsoft documents the standard numeric format strings which generally work with all primitive numeric types' ToString()
methods. This same pattern is used for other types as well: for example, standard date/time format strings can be used with DateTime.ToString()
.
import numpy as np
a = [2,2,2]
b = [1,1,1]
np.subtract(a,b)
Yes you can access them. You should declare them in 'public space' (outside any functions) as:
var globalvar1 = 'value';
You can access them later on, also in other files.
Try this, it worked for me in a similar case:-
$http.get("your api url", {
headers: {
'If-Modified-Since': '0',
"Pragma": "no-cache",
"Expires": -1,
"Cache-Control": "no-cache, no-store, must-revalidate"
}
})
POSIX sh doesn't understand ==
for string equality, as that is a bash-ism. Use =
instead.
The other people saying that brackets aren't supported by sh are wrong, btw.
