Also, I used array to make it simple.... you can directly take integer input and convert it into string and send it to file. input-convert-Write-Process... its that simple.
There are multiple answers to this question, partly due to ambiguous question - the title is talking about classes loaded by the JVM, whereas the contents of the question says "may or may not be loaded by the JVM".
Assuming that OP needs classes that are loaded by the JVM by a given classloader, and only those classes - my need as well - there is a solution (elaborated here) that goes like this:
import java.net.URL;
import java.util.Enumeration;
import java.util.Iterator;
import java.util.Vector;
public class CPTest {
private static Iterator list(ClassLoader CL)
throws NoSuchFieldException, SecurityException,
IllegalArgumentException, IllegalAccessException {
Class CL_class = CL.getClass();
while (CL_class != java.lang.ClassLoader.class) {
CL_class = CL_class.getSuperclass();
}
java.lang.reflect.Field ClassLoader_classes_field = CL_class
.getDeclaredField("classes");
ClassLoader_classes_field.setAccessible(true);
Vector classes = (Vector) ClassLoader_classes_field.get(CL);
return classes.iterator();
}
public static void main(String args[]) throws Exception {
ClassLoader myCL = Thread.currentThread().getContextClassLoader();
while (myCL != null) {
System.out.println("ClassLoader: " + myCL);
for (Iterator iter = list(myCL); iter.hasNext();) {
System.out.println("\t" + iter.next());
}
myCL = myCL.getParent();
}
}
}
One of the neat things about it is that you can choose an arbitrary classloader you want to check. It is however likely to break should internals of classloader class change, so it is to be used as one-off diagnostic tool.

Below given some information about fav Icon
What Is FavIcon? ? FavIcon is nothing but small image which appears top left along with the application address bar title.Standard size specification for favicon.ico is 16 by 16 pixel. Please see below attached figure.
How It Works ? ? Usually we add our FavIcon.ico image in the route solution folder and automatically application picks it while running. But most of the time we might have to use below both link reference.
<link rel="icon" href="favicon.ico" type="image/ico"/>
<link rel="shortcut icon" href="favicon.ico" type="image/x-icon"/>
Some browser expect one (rel="icon") Some other browser expect other rel="shortcut icon"
? Type=”image/x-icon” OR Type=”image/ico”: once expect exact ico image and one expect any image even formatted from .jpg or .pn ..etc.
? We have to use above two tags to the common pages like – Master page , Main frame which is getting used in all the pages
I Used rowCallBack datatable property it is working fine. PFB :-
"rowCallback": function (row, data, index) {
if ((data[colmindx] == 'colm_value')) {
$(row).addClass('OwnClassName');
}
else if ((data[colmindx] == 'colm_value')) {
$(row).addClass('OwnClassStyle');
}
}
Shouldn't that be
validates_length_of :title, :in => 6..255, :on => :create
so it only works during create?

It sounds very much like you're using an array to store different fields. This is definitely a code smell. I'd avoid using arrays as much as possible as they're generally not suitable (or needed) in high-level code.
Switching to a simple Dictionary may be a workable option in the short term. As would using a big property bag class. There are lots of options. The problem you have now is just a symptom of bad design, you should look at fixing the underlying problem rather than just patching the bad design so it kinda, sorta mostly works, for now.
In some cases, when you check your default encoding (print sys.getdefaultencoding()
), it returns that you are using ASCII. If you change to UTF-8, it doesn't work, depending on the content of your variable.
I found another way:
import sys
reload(sys)
sys.setdefaultencoding('Cp1252')
This problem normally appears while copy pasting the tag lib URL from the internet. Usually the quotes ""
in which the URL http://www.springframework.org/tags is embedded might not be correct. Try removing quotes and type them manually. This resolved the issue for me.
Instead of "w"
use "a"
(append) mode with open
function:
with open("games.txt", "a") as text_file:
the simplest way to convert a string that has a delimiter like a comma is just to use the split method
"1,2,3,4".split(',') # "1", "2", "3", "4"]
you can find more info on how to use the split method in the ruby docs
Divides str into substrings based on a delimiter, returning an array of these substrings.
If pattern is a String, then its contents are used as the delimiter when splitting str. If pattern is a single space, str is split on whitespace, with leading whitespace and runs of contiguous whitespace characters ignored.
If pattern is a Regexp, str is divided where the pattern matches. Whenever the pattern matches a zero-length string, str is split into individual characters. If pattern contains groups, the respective matches will be returned in the array as well.
If pattern is omitted, the value of $; is used. If $; is nil (which is the default), str is split on whitespace as if ` ‘ were specified.
If the limit parameter is omitted, trailing null fields are suppressed. If limit is a positive number, at most that number of fields will be returned (if limit is 1, the entire string is returned as the only entry in an array). If negative, there is no limit to the number of fields returned, and trailing null fields are not suppressed.
The way that I like to do it is like this with a ternary assignment.
var width = isNaN(window.innerWidth) ? window.clientWidth : window.innerWidth;
var height = isNaN(window.innerHeight) ? window.clientHeight : window.innerHeight;
I might point out that, if you run this in the global context that from that point on you could use window.height and window.width.
Works on IE and other browsers as far as I know (I have only tested it on IE11).
Super clean and, if I am not mistaken, efficient.

I think this is along the lines of what you're looking for. It appears that you want to see the orderid, the subtotal for each item in the order and the total amount for the order.
select o1.orderID, o1.subtotal, sum(o2.UnitPrice * o2.Quantity) as order_total from
(
select o.orderID, o.price * o.qty as subtotal
from product p inner join orderitem o on p.ProductID= o.productID
where o.orderID = @OrderId
)as o1
inner join orderitem o2 on o1.OrderID = o2.OrderID
group by o1.orderID, o1.subtotal
If you want to change query params without change the route. see below
example might help you:
current route is : /search
& Target route is(without reload page) : /search?query=love
submit(value: string) {
this.router.navigate( ['.'], { queryParams: { query: value } })
.then(_ => this.search(q));
}
search(keyword:any) {
//do some activity using }
please note : you can use this.router.navigate( ['search']
instead of this.router.navigate( ['.']

I don't know any native cmdlet in powershell but you can use com object instead:
$WshShell = New-Object -comObject WScript.Shell
$Shortcut = $WshShell.CreateShortcut("$Home\Desktop\ColorPix.lnk")
$Shortcut.TargetPath = "C:\Program Files (x86)\ColorPix\ColorPix.exe"
$Shortcut.Save()
you can create a powershell script save as set-shortcut.ps1 in your $pwd
param ( [string]$SourceExe, [string]$DestinationPath )
$WshShell = New-Object -comObject WScript.Shell
$Shortcut = $WshShell.CreateShortcut($DestinationPath)
$Shortcut.TargetPath = $SourceExe
$Shortcut.Save()
and call it like this
Set-ShortCut "C:\Program Files (x86)\ColorPix\ColorPix.exe" "$Home\Desktop\ColorPix.lnk"
If you want to pass arguments to the target exe, it can be done by:
#Set the additional parameters for the shortcut
$Shortcut.Arguments = "/argument=value"
before $Shortcut.Save().
For convenience, here is a modified version of set-shortcut.ps1. It accepts arguments as its second parameter.
param ( [string]$SourceExe, [string]$ArgumentsToSourceExe, [string]$DestinationPath )
$WshShell = New-Object -comObject WScript.Shell
$Shortcut = $WshShell.CreateShortcut($DestinationPath)
$Shortcut.TargetPath = $SourceExe
$Shortcut.Arguments = $ArgumentsToSourceExe
$Shortcut.Save()
I'm in the same spot myself (or was), FWIW I ended up checking out to a samba share on the Linux host and editing that share locally on the Windows machine with notepad++, then I compiled on the Linux box via PuTTY. (We weren't allowed to update the ten y/o versions of the editors on the Linux host and it didn't have Java, so I gave up on X11 forwarding)
Now... I run modern Linux in a VM on my Windows host, add all the tools I want (e.g. CDT) to the VM and then I checkout and build in a chroot jail that closely resembles the RTE.
It's a clunky solution but I thought I'd throw it in to the mix.
Here is a modified version of CsabaS's answer, which accounts for explicit deny access rules. The function goes through all FileSystemAccessRules for a directory, and checks if the current user is in a role which has access to a directory. If no such roles are found or the user is in a role with denied access, the function returns false. To check read rights, pass FileSystemRights.Read to the function; for write rights, pass FileSystemRights.Write. If you want to check an arbitrary user's rights and not the current one's, substitute the currentUser WindowsIdentity for the desired WindowsIdentity. I would also advise against relying on functions like this to determine if the user can safely use the directory. This answer perfectly explains why.
public static bool UserHasDirectoryAccessRights(string path, FileSystemRights accessRights)
{
var isInRoleWithAccess = false;
try
{
var di = new DirectoryInfo(path);
var acl = di.GetAccessControl();
var rules = acl.GetAccessRules(true, true, typeof(NTAccount));
var currentUser = WindowsIdentity.GetCurrent();
var principal = new WindowsPrincipal(currentUser);
foreach (AuthorizationRule rule in rules)
{
var fsAccessRule = rule as FileSystemAccessRule;
if (fsAccessRule == null)
continue;
if ((fsAccessRule.FileSystemRights & accessRights) > 0)
{
var ntAccount = rule.IdentityReference as NTAccount;
if (ntAccount == null)
continue;
if (principal.IsInRole(ntAccount.Value))
{
if (fsAccessRule.AccessControlType == AccessControlType.Deny)
return false;
isInRoleWithAccess = true;
}
}
}
}
catch (UnauthorizedAccessException)
{
return false;
}
return isInRoleWithAccess;
}
I'm in a somewhat similar situation. It's not clear whether you know chunk size in bytes; I usually don't, but the number of records (lines) that is required is known:
def get_line():
with open('4gb_file') as file:
for i in file:
yield i
lines_required = 100
gen = get_line()
chunk = [i for i, j in zip(gen, range(lines_required))]
Update: Thanks nosklo. Here's what I meant. It almost works, except that it loses a line 'between' chunks.
chunk = [next(gen) for i in range(lines_required)]
Does the trick w/o losing any lines, but it doesn't look very nice.
If it is a console application, use Ctrl + F5.
To create a test case template:
"New" -> "JUnit Test Case" -> Select "Class under test" -> Select "Available methods". I think the wizard is quite easy for you.

It is a little tricky. First you can use keytool to put the private key into PKCS12 format, which is more portable/compatible than Java's various keystore formats. Here is an example taking a private key with alias 'mykey' in a Java keystore and copying it into a PKCS12 file named myp12file.p12
.
[note that on most screens this command extends beyond the right side of the box: you need to scroll right to see it all]
keytool -v -importkeystore -srckeystore .keystore -srcalias mykey -destkeystore myp12file.p12 -deststoretype PKCS12
Enter destination keystore password:
Re-enter new password:
Enter source keystore password:
[Storing myp12file.p12]
Now the file myp12file.p12
contains the private key in PKCS12 format which may be used directly by many software packages or further processed using the openssl pkcs12
command. For example,
openssl pkcs12 -in myp12file.p12 -nocerts -nodes
Enter Import Password:
MAC verified OK

Note that this is a private key, and you are responsible for appreciating the security implications of removing it from your Java keystore and moving it around.
Instead of using <source>
tag, use <src>
attribute of <video>
as below and you will see the action.
<video width="320" height="240" src="mov1.mov"></video>
or
you can give multiple tags within the tag, each with a different video source. The browser will automatically go through the list and pick the first one it’s able to play. For example:
<video id="sampleMovie" width="640" height="360" preload controls>
<source src="HTML5Sample_H264.mov" />
<source src="HTML5Sample_Ogg.ogv" />
<source src="HTML5Sample_WebM.webm" />
</video>
If you test that code in Chrome, you’ll get the H.264 video. Run it in Firefox, though, and you’ll see the Ogg video in the same place.
I suggest you check out chunked
and disk.frame
. They both have functions for reading in CSVs chunk-by-chunk.
In particular, disk.frame::csv_to_disk.frame
may be the function you are after?
There's a fantastic ORM included in the QCubed framework; it's based on code generation and scaffolding. Unlike the ActiveRecord that's based on reflection and is generally slow, code generation makes skeleton classes for you based on the database and lets you customize them afterward. It works like a charm.
If you are trying to share a project in SVN with Eclipse for the first time, you might want to avoid certain files to be commited. In order to do so, go to Preferences->Team->Ignored Resources. In this screen you just need to add a pattern to ignore the kind of files you don't want to commit.
You need the Clear() function on the list, like so.
List<object> myList = new List<object>();
myList.Add(new object()); // Add something to the list
myList.Clear() // Our list is now empty
This article helped me alot figuring out why it wasn't working for me either. It give me a lesson to think of the webpage loading and how angular 2 interacts as a timeline and not just the point in time i'm thinking of. I didn't see anyone else mention this point, so I will...
The reason the *ngIf is needed because it will try to check the length of that variable before the rest of the OnInit stuff happens, and throw the "length undefined" error. So thats why you add the ? because it won't exist yet, but it will soon.
1 and 2 are SAML 1.1 because those URIs were part of the OASIS SAML 1.1 standard. Section 8.3 of the linked PDF for the OASIS SAML 2.0 standard explains this:
Where possible an existing URN is used to specify a protocol. In the case of IETF protocols, the URN of the most current RFC that specifies the protocol is used. URI references created specifically for SAML have one of the following stems, according to the specification set version in which they were first introduced:
urn:oasis:names:tc:SAML:1.0: urn:oasis:names:tc:SAML:1.1: urn:oasis:names:tc:SAML:2.0:
The shortest way is by adding the ObsoleteAttribute
as an attribute to the method. Make sure to include an appropriate explanation:
[Obsolete("Method1 is deprecated, please use Method2 instead.")]
public void Method1()
{ … }
You can also cause the compilation to fail, treating the usage of the method as an error instead of warning, if the method is called from somewhere in code like this:
[Obsolete("Method1 is deprecated, please use Method2 instead.", true)]
When you write List<String> list = new LinkedList();
, compiler produces an "unchecked" warning. You may ignore it, but if you used to ignore these warnings you may also miss a warning that notifies you about a real type safety problem.
So, it's better to write a code that doesn't generate extra warnings, and diamond operator allows you to do it in convenient way without unnecessary repetition.
JQuery is looking for a json type result, but because the redirect is processed automatically, it will receive the generated html source of your login.htm
page.
One idea is to let the the browser know that it should redirect by adding a redirect
variable to to the resulting object and checking for it in JQuery:
$(document).ready(function(){
jQuery.ajax({
type: "GET",
url: "populateData.htm",
dataType:"json",
data:"userId=SampleUser",
success:function(response){
if (response.redirect) {
window.location.href = response.redirect;
}
else {
// Process the expected results...
}
},
error: function(xhr, textStatus, errorThrown) {
alert('Error! Status = ' + xhr.status);
}
});
});
You could also add a Header Variable to your response and let your browser decide where to redirect. In Java, instead of redirecting, do response.setHeader("REQUIRES_AUTH", "1")
and in JQuery you do on success(!):
//....
success:function(response){
if (response.getResponseHeader('REQUIRES_AUTH') === '1'){
window.location.href = 'login.htm';
}
else {
// Process the expected results...
}
}
//....
Hope that helps.
My answer is heavily inspired by this thread which shouldn't left any questions in case you still have some problems.
In the context of an enum, using @JsonValue
now (since 2.0) works for serialization and deserialization.
According to the jackson-annotations javadoc for @JsonValue
:
NOTE: when use for Java enums, one additional feature is that value returned by annotated method is also considered to be the value to deserialize from, not just JSON String to serialize as. This is possible since set of Enum values is constant and it is possible to define mapping, but can not be done in general for POJO types; as such, this is not used for POJO deserialization.
So having the Event
enum annotated just as above works (for both serialization and deserialization) with jackson 2.0+.
I was receiving this similar error when compiling my Node.JS Typescript application:
node_modules/@types/node/index.d.ts:83:15 - error TS2451: Cannot redeclare block-scoped variable 'custom'.
The fix was to remove this:
"files": [
"./node_modules/@types/node/index.d.ts"
]
and to replace it with this:
"compilerOptions": {
"types": ["node"]
}
To build on the answer by @RQDQ using generics, you can combine this with Func<TResult>
(or some variation) and delegate responsibility to the caller:
public T GetAnything<T>(Func<T> createInstanceOfT)
{
//do whatever
return createInstanceOfT();
}
Then you can do something like:
Computer comp = GetAnything(() => new Computer());
Radio rad = GetAnything(() => new Radio());
From MSDN: System.Threading.Timer
is a simple, lightweight timer that uses callback methods and is served by thread pool threads. It is not recommended for use with Windows Forms, because its callbacks do not occur on the user interface thread. System.Windows.Forms.Timer
is a better choice for use with Windows Forms. For server-based timer functionality, you might consider using System.Timers.Timer
, which raises events and has additional features.
My personal preference is to delete the branch name after I’m done with a topic branch.
Instead of trying to use the branch name to explain the meaning of the branch, I start the subject line of the commit message in the first commit on that branch with “Branch:” and include further explanations in the body of the message if the subject does not give me enough space.
The branch name in my use is purely a handle for referring to a topic branch while working on it. Once work on the topic branch has concluded, I get rid of the branch name, sometimes tagging the commit for later reference.
That makes the output of git branch
more useful as well: it only lists long-lived branches and active topic branches, not all branches ever.
You can also do this using NotificationCenter in Swift 4
NotificationCenter.default.addObserver(self, selector: #selector(self.handleTextChange(recognizer:)), name: NSNotification.Name.UITextFieldTextDidChange, object: yourTextField)
@objc func handleTextChange(recognizer: NSNotification) {
//max length is 50 charater max
let textField = recognizer.object as! UITextField
if((textField.text?.count)! > 50) {
let newString: String? = (textField.text as NSString?)?.substring(to: 50)
textField.text = newString
}
}
try
$arr = array('var1' => 100, 'var2' => 200);
$json = json_encode( $arr, JSON_NUMERIC_CHECK);
But it just work on PHP 5.3.3. Look at this PHP json_encode change log http://php.net/manual/en/function.json-encode.php#refsect1-function.json-encode-changelog
Note that if you use DictWriter, you will have a new line from the open function and a new line from the writerow function. You can use newline='' within the open function to remove the extra newline.
But I wanted to point out that the opinion expressed in the accepted answer is somewhat outdated. According to more recent discussions (django bugs #7634 and #12785), auto_now and auto_now_add are not going anywhere, and even if you go to the original discussion, you'll find strong arguments against the RY (as in DRY) in custom save methods.
A better solution has been offered (custom field types), but didn't gain enough momentum to make it into django. You can write your own in three lines (it's Jacob Kaplan-Moss' suggestion).
from django.db import models
from django.utils import timezone
class AutoDateTimeField(models.DateTimeField):
def pre_save(self, model_instance, add):
return timezone.now()
#usage
created_at = models.DateField(default=timezone.now)
updated_at = models.AutoDateTimeField(default=timezone.now)
the getText
method returns a String, while the setText
receives a String, so you can write it like label1.setText(nameField.getText());
in your listener.
os.makedirs
is what you need. For chmod
or chown
you'll have to use os.walk
and use it on every file/dir yourself.
If the field contains a leading space, Excel ignores the double quote as a text qualifier. The solution is to eliminate leading spaces between the comma (field separator) and double-quote. For example:
Broken:
Name,Title,Description
"John", "Mr.", "My detailed description"
Working:
Name,Title,Description
"John","Mr.","My detailed description"
Wrap it in a function:
create function now_utc() returns timestamp as $$
select now() at time zone 'utc';
$$ language sql;
create temporary table test(
id int,
ts timestamp without time zone default now_utc()
);
You can use Microsoft's MapPoint Web Services.
I created a blog entry on how to convert an address to a GeoCode (lat/long).
Have you check your php.ini ?
I broken my post method once that I set post_max_size
the same with upload_max_filesize
.
I think that post_max_size
must less than upload_max_filesize
.

Try this -
select * from table where id in (3,4) or [name] in ('andy','paul');
I prefer not to use awk
and such in scripts.. ip
has the option to output in JSON.
If you leave out $interface
then you get all of the ip addresses:
ip -json addr show $interface | \
jq -r '.[] | .addr_info[] | select(.family == "inet") | .local'
like already said, in java-8 we have the concise solution by Collectors:
list.stream().collect(
groupingBy(Item::getKey)
)
and also, you can nest multiple group passing an other groupingBy method as second parameter:
list.stream().collect(
groupingBy(Item::getKey, groupingBy(Item::getOtherKey))
)
In this way, we'll have multi level map, like this: Map<key, Map<key, List<Item>>>
Below are the steps to do revoke your JWT access token:
Please let me know if you need more details, I can share the code (Java + Spring boot) as well.
For your questions:
Q1: It's another JWT with fewer claims put in with long expiry time.
Q2: It won't be in a database. The backend will not store anywhere. They will just decrypt the token with private/public key and validate it with its expiry time also.
Q3: Yes, Correct
If it’s one table only then all you need to do is
One thing you’ll have to consider is other updates such as migrating other objects in the future. Note that your source and destination tables do not have the same name. This means that you’ll also have to make changes if you dependent objects such as views, stored procedures and other.
Whit one or several objects you can go manually w/o any issues. However, when there are more than just a few updates 3rd party comparison tools come in very handy. Right now I’m using ApexSQL Diff for schema migrations but you can’t go wrong with any other tool out there.
I ran into the same issue but the accepted solution did not work for me. Instead the solution was to modify the framework's install name.

Note the first path after Library not loaded. The framework is being loaded from an absolute path. This path comes from the framework's install name (sometimes called rpath), which can be examined using:
otool -D MyFramework.framework/MyFramework
When a framework is embedded into an app this path should be relative and of this form: @rpath/MyFramework.framework/MyFramework. If your framework's install name is an absolute path it may not be loaded at runtime and an error similar to the one above will be produced.
The solution is to modify the install name:
install_name_tool -id "@rpath/MyFramework.framework/MyFramework" MyFramework.framework/MyFramework
With this change I no longer get the error
You can generalize this into a function that lets you choose the output format
private String substractDates(Date date1, Date date2, SimpleDateFormat format) {
long restDatesinMillis = date1.getTime()-date2.getTime();
Date restdate = new Date(restDatesinMillis);
return format.format(restdate);
}
Now is a simple function call like this, difference in hours, minutes and seconds:
SimpleDateFormat formater = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
try {
Date date1 = formater.parse(dateEnd);
Date date2 = formater.parse(dateInit);
String result = substractDates(date1, date2, new SimpleDateFormat("HH:mm:ss"));
txtTime.setText(result);
} catch (ParseException e) {
e.printStackTrace();
}
With my mercurial background I was going to use:
git log --patch -1 $ID > $file
But I am considering using git format-patch -1 $ID
now.
I am surprised that in almost ten years, no one has posted this approach yet:
If using older versions of bash where &>>
isn't available, you also can do:
(cmd 2>&1) >> file.txt
This spawns a subshell, so it's less efficient than the traditional approach of cmd >> file.txt 2>&1
, and it consequently won't work for commands that need to modify the current shell (e.g. cd
, pushd
), but this approach feels more natural and understandable to me:
Also, the parentheses remove any ambiguity of order, especially if you want to pipe stdout and stderr to another command instead.
Edit: To avoid starting a subshell, you instead could use curly braces instead of parentheses to create a group command:
{ cmd 2>&1; } >> file.txt
(Note that a semicolon (or newline) is required to terminate the group command.)

Recently Raymond Chen also ran an interesting series of articles on the yield keyword.
While it's nominally used for easily implementing an iterator pattern, but can be generalized into a state machine. No point in quoting Raymond, the last part also links to other uses (but the example in Entin's blog is esp good, showing how to write async safe code).
You can use this implementation of Binary GCD algorithm
public class BinaryGCD {
public static int gcd(int p, int q) {
if (q == 0) return p;
if (p == 0) return q;
// p and q even
if ((p & 1) == 0 && (q & 1) == 0) return gcd(p >> 1, q >> 1) << 1;
// p is even, q is odd
else if ((p & 1) == 0) return gcd(p >> 1, q);
// p is odd, q is even
else if ((q & 1) == 0) return gcd(p, q >> 1);
// p and q odd, p >= q
else if (p >= q) return gcd((p-q) >> 1, q);
// p and q odd, p < q
else return gcd(p, (q-p) >> 1);
}
public static void main(String[] args) {
int p = Integer.parseInt(args[0]);
int q = Integer.parseInt(args[1]);
System.out.println("gcd(" + p + ", " + q + ") = " + gcd(p, q));
}
}

I also encountered this problem because I install Ruby on Ubuntu via brightbox, and I thought ruby-dev is the trunk of ruby. So I did not install. Install ruby2.3-dev fixes it:
sudo apt-get install ruby2.3-dev
This method should help to programmatically generate values guaranteed to be 100% compatible with .properties
files:
public static String escapePropertyValue(final String value) {
if (value == null) {
return null;
}
try (final StringWriter writer = new StringWriter()) {
final Properties properties = new Properties();
properties.put("escaped", value);
properties.store(writer, null);
writer.flush();
final String stringifiedProperties = writer.toString();
final Pattern pattern = Pattern.compile("(.*?)escaped=(.*?)" + Pattern.quote(System.lineSeparator()) + "*");
final Matcher matcher = pattern.matcher(stringifiedProperties);
if (matcher.find() && matcher.groupCount() <= 2) {
return matcher.group(matcher.groupCount());
}
// This should never happen unless the internal implementation of Properties::store changed
throw new IllegalStateException("Could not escape property value");
} catch (final IOException ex) {
// This should never happen. IOException is only because the interface demands it
throw new IllegalStateException("Could not escape property value", ex);
}
}
You can call it like this:
final String escapedPath = escapePropertyValue("C:\\Users\\X");
writeToFile(escapedPath); // will pass "C\\:\\\\Users\\\\X"
This method a little bit expensive but, writing properties to a file is typically an sporadic operation anyway.
use this expression
var RegExpression = /^[a-zA-Z\s]*$/;
for more refer this http://tools.netshiftmedia.com
The solution is the /Y
switch:
xcopy "C:\Users\ADMIN\Desktop\*.*" "D:\Backup\" /K /D /H /Y
If you need to do a complex regexp replacement including \r\n, you can workaround the limitation by a three-step approach:
\r\n
by a tag, let's say #GO#
? Check 'Extended', replace \r\n
by #GO#
ICON="*"
from an html bookmarks ? Check regexp, replace ICON=.[^"]+.> by >
#GO#
by \r\n
You should use jquery validation because if you use type="number"
then you can also enter "E" character in input type, which is not correct.
Solution:
HTML
<input class="form-control floatNumber" name="energy1_total_power_generated" type="text" required="" >
JQuery
//integer value validation
$('input.floatNumber').on('input', function() {
this.value = this.value.replace(/[^0-9.]/g,'').replace(/(\..*)\./g, '$1');
});
Try this way,hope this will help you to solve your problem.

As ivan.sim writes in his answer
- Ensure that your user account has administrator privilege.
- Disable UAC(User Account Control) as it restricts certain administrative function needed to run a web server.
- Install in C://xampp.
Problem with the correct answer is in the explanation of point 2., and magicandre1981 writes more about it
Moving the slider down doesn't completely disable UAC since Windows 8. This is changed compared to Windows 7, because the new Store apps require an active UAC. With UAC off, they no longer run.
How can we then disable UAC and install XAMPP?
Easy. Go to Registry Editor and navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
Right click EnableLUA and modify the Value data to 0.
Then restart your computer and you're ready to install XAMPP.
By using the hibernate @Transactional
annotation, if you get an object from the database with lazy fetched attributes, you can simply get these by fetching these attributes like this :
@Transactional
public void checkTicketSalePresence(UUID ticketUuid, UUID saleUuid) {
Optional<Ticket> savedTicketOpt = ticketRepository.findById(ticketUuid);
savedTicketOpt.ifPresent(ticket -> {
Optional<Sale> saleOpt = ticket.getSales().stream().filter(sale -> sale.getUuid() == saleUuid).findFirst();
assertThat(saleOpt).isPresent();
});
}
Here, in an Hibernate proxy-managed transaction, the fact of calling ticket.getSales()
do another query to fetch sales because you explicitly asked it.

If you're already in conflicted state, and you want to just accept all of theirs:
git checkout --theirs .
git add .
If you want to do the opposite:
git checkout --ours .
git add .
This is pretty drastic, so make sure you really want to wipe everything out like this before doing it.
It flushes the internal buffer, which is supposed to cause the OS to write out the buffer to the file.[1] Python uses the OS's default buffering unless you configure it do otherwise.
But sometimes the OS still chooses not to cooperate. Especially with wonderful things like write-delays in Windows/NTFS. Basically the internal buffer is flushed, but the OS buffer is still holding on to it. So you have to tell the OS to write it to disk with os.fsync()
in those cases.
TL;DR:
SOLUTION (1)
import numpy as np
main_list = np.setdiff1d(list_2,list_1)
# yields the elements in `list_2` that are NOT in `list_1`
SOLUTION (2) You want a sorted list
def setdiff_sorted(array1,array2,assume_unique=False):
ans = np.setdiff1d(array1,array2,assume_unique).tolist()
if assume_unique:
return sorted(ans)
return ans
main_list = setdiff_sorted(list_2,list_1)
EXPLANATIONS:
(1) You can use NumPy's setdiff1d
(array1
,array2
,assume_unique
=False
).
assume_unique
asks the user IF the arrays ARE ALREADY UNIQUE.
If False
, then the unique elements are determined first.
If True
, the function will assume that the elements are already unique AND function will skip determining the unique elements.
This yields the unique values in array1
that are not in array2
. assume_unique
is False
by default.
If you are concerned with the unique elements (based on the response of Chinny84), then simply use (where assume_unique=False
=> the default value):
import numpy as np
list_1 = ["a", "b", "c", "d", "e"]
list_2 = ["a", "f", "c", "m"]
main_list = np.setdiff1d(list_2,list_1)
# yields the elements in `list_2` that are NOT in `list_1`
(2)
For those who want answers to be sorted, I've made a custom function:
import numpy as np
def setdiff_sorted(array1,array2,assume_unique=False):
ans = np.setdiff1d(array1,array2,assume_unique).tolist()
if assume_unique:
return sorted(ans)
return ans
To get the answer, run:
main_list = setdiff_sorted(list_2,list_1)
SIDE NOTES:
(a) Solution 2 (custom function setdiff_sorted
) returns a list (compared to an array in solution 1).
(b) If you aren't sure if the elements are unique, just use the default setting of NumPy's setdiff1d
in both solutions A and B. What can be an example of a complication? See note (c).
(c) Things will be different if either of the two lists is not unique.
Say list_2
is not unique: list2 = ["a", "f", "c", "m", "m"]
. Keep list1
as is: list_1 = ["a", "b", "c", "d", "e"]
Setting the default value of assume_unique
yields ["f", "m"]
(in both solutions). HOWEVER, if you set assume_unique=True
, both solutions give ["f", "m", "m"]
. Why? This is because the user ASSUMED that the elements are unique). Hence, IT IS BETTER TO KEEP assume_unique
to its default value. Note that both answers are sorted.
My main purpose was to get ICONs for TortoiseCVS. Many of the suggestions did not work for me: uninstall reinstall; regedit by renaming; rebooting multiple times. But what did work was to install TortoiseSVN. This made the icons for TortoiseCVS work. I checked out regedit. The SVN install put numbers in front of the icon names:

By using this website you can get Hash Key by Converting SHA1 key to Hash Key for Facebook.
function someFunction(site) {
if (site.indexOf('/') > 0)

Generally, this error comes because we don’t make default constructor.
But in my case:
The issue was coming only due to I have made used object class inside parent class.
This has wasted my whole day.
You can center a fixed
or absolute
positioned element setting right
and left
to 0
, and then margin-left
& margin-right
to auto
as if you were centering a static
positioned element.
#example {
position: fixed;
/* center the element */
right: 0;
left: 0;
margin-right: auto;
margin-left: auto;
/* give it dimensions */
min-height: 10em;
width: 90%;
}
Suppose logical address space is **32 bit so total possible logical entries will be 2^32 and other hand suppose each page size is 4 byte then size of one page is *2^2*2^10=2^12...* now we know that no. of pages in page table is pages=total possible logical address entries/page size so pages=2^32/2^12 =2^20 Now suppose that each entry in page table takes 4 bytes then total size of page table in *physical memory will be=2^2*2^20=2^22=4mb***
In my experience it's best to put as much code as you can into well-named modules, and only put as much code as you need to into the actual worksheet objects.
Example: Any code that uses worksheet events like Worksheet_SelectionChange or Worksheet_Calculate.
If we are not sure that the list is sorted, we could use the built-in min()
function, to find the element which has the minimum distance from the specified number.
>>> min(myList, key=lambda x:abs(x-myNumber))
4
Note that it also works with dicts with int keys, like {1: "a", 2: "b"}
. This method takes O(n) time.
If the list is already sorted, or you could pay the price of sorting the array once only, use the bisection method illustrated in @Lauritz's answer which only takes O(log n) time (note however checking if a list is already sorted is O(n) and sorting is O(n log n).)
You could try this:
<input type="file" capture="camera" accept="image/*" id="cameraInput" name="cameraInput">
but it has to be iOS 6+ to work. That will give you a nice dialogue for you to choose either to take a picture or to upload one from your album i.e.
An example can be found here: Capturing camera/picture data without PhoneGap
I normally use the killall
command.

I created a batch file with the following code in a windows machine to monitor every second. It works for me.
:loop
cls
"C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi"
timeout /T 1
goto loop
nvidia-smi exe is usually located in "C:\Program Files\NVIDIA Corporation" if you want to run the command only once.
Enable:
adb shell su -c 'svc wifi enable'
Disable:
adb shell su -c 'svc wifi disable'
adb shell am start -a android.intent.action.MAIN -n com.android.settings/.wifi.WifiSettings
adb shell input keyevent 20 & adb shell input keyevent 23
The first line launch "wifi.WifiSettings" activity which open the WiFi Settings page. The second line simulate key presses.
I tested those two lines on a Droid X. But Key Events above probably need to edit in other devices because of different Settings layout.

There is a slight problem with ImageIcon
in that the constructor blocks reading the image. Not really a problem when loading from the application jar, but maybe if you're potentially reading over a network connection. There's plenty of AWT-era examples of using MediaTracker

You only need to clear your list on OnPostExecute()
and not while doing Pull to Refresh
// Setup refresh listener which triggers new data loading
swipeContainer.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
AsyncTask<String,Void,String> task = new get_listings();
task.execute(); // clear listing inside onPostExecute
}
});
I discovered that this happens when you scroll during a pull to refresh, since I was clearing the list before the async task
, resulting to java.lang.IndexOutOfBoundsException: Inconsistency detected.
swipeContainer.setRefreshing(false);
//TODO : This is very crucial , You need to clear before populating new items
listings.clear();
That way you won't end with an inconsistency

In the recent Python version, subprocess
has a big change. It offers a brand-new class Popen
to handle os.popen1|2|3|4
.
The new subprocess.Popen()
import subprocess
subprocess.Popen('ls -la', shell=True)
Its arguments:
subprocess.Popen(args,
bufsize=0,
executable=None,
stdin=None, stdout=None, stderr=None,
preexec_fn=None, close_fds=False,
shell=False,
cwd=None, env=None,
universal_newlines=False,
startupinfo=None,
creationflags=0)
Simply put, the new Popen
includes all the features which were split into 4 separate old popen
.
The old popen
:
Method Arguments
popen stdout
popen2 stdin, stdout
popen3 stdin, stdout, stderr
popen4 stdin, stdout and stderr

For anyone else who comes here looking, I'm afraid I'm with @usama sulaiman here.
Using the enqueue function provides a safe way to load style sheets and scripts according to the script dependencies and is WordPress' recommended method of achieving what the original poster was trying to achieve. Just think of all the plugins trying to load their own copy of jQuery for instance; you better hope they're using enqueue :D.
Also, wherever possible create a plugin; as adding custom code to your functions file can be pita if you don't have a back-up and you upgrade your theme and overwrite your functions file in the process.
Having a plugin handle this and other custom functions also means you can switch them off if you think their code is clashing with some other plugin or functionality.
Something along the following in a plugin file is what you are looking for:
<?php
/*
Plugin Name: Your plugin name
Description: Your description
Version: 1.0
Author: Your name
Author URI:
Plugin URI:
*/
function $yourJS() {
wp_enqueue_script(
'custom_script',
plugins_url( '/js/your-script.js', __FILE__ ),
array( 'jquery' )
);
}
add_action( 'wp_enqueue_scripts', '$yourJS' );
add_action( 'wp_enqueue_scripts', 'prefix_add_my_stylesheet' );
function prefix_add_my_stylesheet() {
wp_register_style( 'prefix-style', plugins_url( '/css/your-stylesheet.css', __FILE__ ) );
wp_enqueue_style( 'prefix-style' );
}
?>
Structure your folders as follows:
Plugin Folder
|_ css folder
|_ js folder
|_ plugin.php ...contains the above code - modified of course ;D
Then zip it up and upload it to your WordPress installation using your add plugins interface, activate it and Bob's your uncle.
This is one way:
.your-selector:empty::after {
content: ".";
visibility: hidden;
}
when I add the padding-left property, the width of the DIV changes to 220px
Yes, that is exactly according to the standards. That's how it's supposed to work.
Let's say I create another DIV named anotherdiv exactly the same as newdiv, and put it inside of newdiv but newdiv has no padding and anotherdiv has padding-left: 20px. I get the same thing, newdiv's width will be 220px;
No, newdiv will remain 200px wide.
If you have tried everything still no luck you can try this :_
1 -> Uninstall NVM
rm -rf ~/.nvm
2 -> Remove npm dependencies by following this
3 -> Install NVM
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
4 -> Set ~/.bash_profile
configuration
Run sudo nano ~/.bash_profile
Copy and paste following this
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
5 -> CONTROL + X
save the changes
6 -> Run . ~/.bash_profile
7 -> Now you should have nvm
installed on your machine, to install node run nvm install v7.8.0
this will be default node version or you can install any version of node
Do C-b
, :show
which will show you all your current settings. /green
, nnn
will find you which properties have been set to green, the default. Do C-b
, :set window-status-bg cyan
and the bottom bar should change colour.
List available colours for tmux
You can tell more easily by the titles and the colours as they're actually set in your live session :show
, than by searching through the man
page, in my opinion. It is a very well-written man
page when you have the time though.
If you don't like one of your changes and you can't remember how it was originally set, you can open do a new tmux session. To change settings for good edit ~/.tmux.conf
with a line like set window-status-bg -g cyan
. Here's mine: https://gist.github.com/9083598
Instead of using regex, it is generally better to parse the string as a datetime.datetime
object:
In [140]: datetime.datetime.strptime("11/12/98","%m/%d/%y")
Out[140]: datetime.datetime(1998, 11, 12, 0, 0)
In [141]: datetime.datetime.strptime("11/12/98","%d/%m/%y")
Out[141]: datetime.datetime(1998, 12, 11, 0, 0)
You could then access the day, month, and year (and hour, minutes, and seconds) as attributes of the datetime.datetime
object:
In [143]: date.year
Out[143]: 1998
In [144]: date.month
Out[144]: 11
In [145]: date.day
Out[145]: 12
To test if a sequence of digits separated by forward-slashes represents a valid date, you could use a try..except
block. Invalid dates will raise a ValueError
:
In [159]: try:
.....: datetime.datetime.strptime("99/99/99","%m/%d/%y")
.....: except ValueError as err:
.....: print(err)
.....:
.....:
time data '99/99/99' does not match format '%m/%d/%y'
If you need to search a longer string for a date, you could use regex to search for digits separated by forward-slashes:
In [146]: import re
In [152]: match = re.search(r'(\d+/\d+/\d+)','The date is 11/12/98')
In [153]: match.group(1)
Out[153]: '11/12/98'
Of course, invalid dates will also match:
In [154]: match = re.search(r'(\d+/\d+/\d+)','The date is 99/99/99')
In [155]: match.group(1)
Out[155]: '99/99/99'
To check that match.group(1)
returns a valid date string, you could then parsing it using datetime.datetime.strptime
as shown above.
I would actually create a template for it and use that template with an EditorFor().
Here is how I did it:
Create My template, which is basically a partial view I created in the EditorTemplates directory, under Shared, under Views name it as (for example): CheckboxTemplate
:
@using System.Globalization
@using System.Web.Mvc.Html
@model bool?
@{
bool? myModel = false;
if (Model.HasValue)
{
myModel = Model.Value;
}
}
<input type="checkbox" checked="@(myModel)" name="@ViewData.TemplateInfo.HtmlFieldPrefix" value="True" style="width:20px;" />
Use it like this (in any view):
@Html.EditorFor(x => x.MyNullableBooleanCheckboxToBe, "CheckboxTemplate")
Thats all.
Templates are so powerful in MVC, use them.. You can create an entire page as a template, which you would use with the @Html.EditorFor()
; provided that you pass its view model in the lambda expression..

SOLVED:
The above did not help. Then I simply installed sklearn from within Jypyter-lab, even though sklearn 0.0 shows in 'pip list':
!pip install sklearn
import sklearn
What I learned later is that pip installs, in my case, packages in a different folder than Jupyter. This can be seen by executing:
import sys
print(sys.path)
Once from within Jupyter_lab notebook, and once from the command line using 'py notebook.py'.
In my case Jupyter list of paths where subfolders of 'anaconda' whereas Python list where subfolders of c:\users[username]...
Others have mentioned Moment. Moment is great but very large for a simple use like this, and unfortunately not modular so you have to import the whole package to use any of it.
I recommend using date-fns (https://date-fns.org/) (https://github.com/date-fns/date-fns). It is light-weight and modular, so you can import only the functions that you need.
Install it: npm install date-fns --save
In your component:
import { format } from "date-fns";
var date = new Date("2016-01-04 10:34:23");
var formattedDate = format(date, "MMMM do, yyyy H:mma");
console.log(formattedDate);
Substitute the format string above "MMMM do, yyyy H:mma"
with whatever format you require.
v1 used Y
for year and D
for day, while v2 uses y
and d
. Format strings above have been updated for v2; the equivalent for v1 would be "MMMM Do, YYYY H:mma"
(source: https://blog.date-fns.org/post/unicode-tokens-in-date-fns-v2-sreatyki91jg/). Thanks @Red
All these answers around here, as well as the answers in this question, suggest that loading absolute URLs, like "/foo/bar.properties" treated the same by class.getResourceAsStream(String)
and class.getClassLoader().getResourceAsStream(String)
. This is NOT the case, at least not in my Tomcat configuration/version (currently 7.0.40).
MyClass.class.getResourceAsStream("/foo/bar.properties"); // works!
MyClass.class.getClassLoader().getResourceAsStream("/foo/bar.properties"); // does NOT work!
Sorry, I have absolutely no satisfying explanation, but I guess that tomcat does dirty tricks and his black magic with the classloaders and cause the difference. I always used class.getResourceAsStream(String)
in the past and haven't had any problems.
PS: I also posted this over here
Although answer has been already provided by @brabster and others.
I think more reusable solution would be:

In your quesion code you are using TimeSpan.FromMinutes
incorrectly. Please see the MSDN Documentation for TimeSpan.FromMinutes, which gives the following method signature:
public static TimeSpan FromMinutes(double value)
hence, the following code won't compile
var intMinutes = TimeSpan.FromMinutes(varTime); // won't compile
Instead, you can use the TimeSpan.TotalMinutes property to perform this arithmetic. For instance:
TimeSpan varTime = (DateTime)varFinish - (DateTime)varValue;
double fractionalMinutes = varTime.TotalMinutes;
int wholeMinutes = (int)fractionalMinutes;
For primitives, if you want to avoid boxing, Guava has helpers for primitive arrays e.g. Ints.indexOf(int[] array, int target)
when using String array, you have to give size of array while initializing
eg
String[] str = new String[10];
you can use index 0-9 to store values
str[0] = "value1"
str[1] = "value2"
str[2] = "value3"
str[3] = "value4"
str[4] = "value5"
str[5] = "value6"
str[6] = "value7"
str[7] = "value8"
str[8] = "value9"
str[9] = "value10"
if you are using ArrayList instread of string array, you can use it without initializing size of array ArrayList str = new ArrayList();
you can add value by using add method of Arraylist
str.add("Value1");
get retrieve a value from arraylist, you can use get method
String s = str.get(0);
find total number of items by size method
int nCount = str.size();

If all you need is mousedown, you may be able to make do with the document.elementFromPoint

int resId = this.getResources().getIdentifier("imageNameHere", "drawable", this.getPackageName());
You should be able to see the schema by running

// Once finished with the bitmap objects, we deallocate them.
originalBMP.Dispose();
bannerBMP.Dispose();
oGraphics.Dispose();
This is a programming style that you'll regret sooner or later. Sooner is knocking on the door, you forgot one. You are not disposing newBitmap. Which keeps a lock on the file until the garbage collector runs. If it doesn't run then the second time you try to save to the same file you'll get the klaboom. GDI+ exceptions are too miserable to give a good diagnostic so serious head-scratching ensues. Beyond the thousands of googlable posts that mention this mistake.
Always favor using the using statement. Which never forgets to dispose an object, even if the code throws an exception.
using (var newBitmap = new Bitmap(thumbBMP)) {
newBitmap.Save("~/image/thumbs/" + "t" + objPropBannerImage.ImageId, ImageFormat.Jpeg);
}
Albeit that it is very unclear why you even create a new bitmap, saving thumbBMP should already be good enough. Anyhoo, give the rest of your disposable objects the same using love.
Suspended. The session is waiting for an event, such as I/O, to complete.
In general, you need to use this feature when you don't want or don't have time to deal with a huge table. If this is your case, it's better to use --where option from mysqldump limiting resultset. For example, mysqldump -uuser -ppass database --where="1 = 1 LIMIT 500000" > resultset.sql
.
There are two important points to consider:
Who creates objects
What kind of objects it manages:
Application module for creating order which contains multiple entries called orderline.
Let's assume we want to create following layer architecture:
Domain objects may be objects stored inside database.
Repository (DAO) helps with retrievar of objects from database.
Service provides API to other modules. Alows for operations on order
module
Entities which will be in the database are Order and OrderLine. Order can have multiple OrderLines.
Now comes important design part. Should modules outside this one create and manage OrderLines on their own? No. Order Line should exist only when you have Order associated with it. It would be best if you could hide internal implementaiton to outside classes.
But how to create Order without knowledge about OrderLines?
Factory
Someone who wants to create new order used OrderFactory (which will hide details about the fact how we create Order).
Thats how it will look inside IDE. Classes outside domain
package will use OrderFactory
instead of constructor inside Order
OrderRepository and OrderService are managed by dependency injection framework. Repository is responsible for managing CRUD operations on database. Service injects Repository and uses it to save/find correct domain classes.

Boolean types are defined in documentation:
http://docs.python.org/library/stdtypes.html#boolean-values
Quoted from doc:
Boolean values are the two constant objects False and True. They are used to represent truth values (although other values can also be considered false or true). In numeric contexts (for example when used as the argument to an arithmetic operator), they behave like the integers 0 and 1, respectively. The built-in function bool() can be used to cast any value to a Boolean, if the value can be interpreted as a truth value (see section Truth Value Testing above).
They are written as False and True, respectively.
So in java code remove braces, change true
to True
and you will be ok :)
In SVG (contrasted with HTML), you will want to use <image>
instead of <img>
for elements.
Try changing your last block with:
var imgs = svg.selectAll("image").data([0]);
imgs.enter()
.append("svg:image")
...
Another option is to use placeholders.
Html:
<body>
<div id="root">
<asp:PlaceHolder ID="iframeDiv" runat="server"/>
</div>
</body>
C#:
iframeDiv.Controls.Add(new LiteralControl("<iframe src=\"" + whatever.com + "\"></iframe><br />"));
bundle is used to share data between activities , and to save state of app in oncreate() method so that app will come to know where it was stopped ... I hope it helps :)
I was searching an answer for this same question and found ENTRYPOINT in Dockerfile solution for me.

Now the scripts are executed when I start the container and I get the bash prompt after the scripts has been executed.
You should use response.content
in this case:
with open('/tmp/metadata.pdf', 'wb') as f:
f.write(response.content)
From the document:
You can also access the response body as bytes, for non-text requests:
>>> r.content b'[{"repository":{"open_issues":0,"url":"https://github.com/...
So that means: response.text
return the output as a string object, use it when you're downloading a text file. Such as HTML file, etc.
And response.content
return the output as bytes object, use it when you're downloading a binary file. Such as PDF file, audio file, image, etc.
You can also use response.raw
instead. However, use it when the file which you're about to download is large. Below is a basic example which you can also find in the document:
import requests
url = 'http://www.hrecos.org//images/Data/forweb/HRTVBSH.Metadata.pdf'
r = requests.get(url, stream=True)
with open('/tmp/metadata.pdf', 'wb') as fd:
for chunk in r.iter_content(chunk_size):
fd.write(chunk)
chunk_size
is the chunk size which you want to use. If you set it as 2000
, then requests will download that file the first 2000
bytes, write them into the file, and do this again, again and again, unless it finished.
So this can save your RAM. But I'd prefer use response.content
instead in this case since your file is small. As you can see use response.raw
is complex.
Relates:
$response
is instance of PSR-7 ResponseInterface
. For more details see https://www.php-fig.org/psr/psr-7/#3-interfaces
getBody()
returns StreamInterface
:
/**
* Gets the body of the message.
*
* @return StreamInterface Returns the body as a stream.
*/
public function getBody();
StreamInterface
implements __toString()
which does
Reads all data from the stream into a string, from the beginning to end.
Therefore, to read body as string, you have to cast it to string:
$stringBody = (string) $response->getBody()
json_decode($response->getBody()
is not the best solution as it magically casts stream into string for you. json_decode()
requires string as 1st argument.$response->getBody()->getContents()
unless you know what you're doing. If you read documentation for getContents()
, it says: Returns the remaining contents in a string
. Therefore, calling getContents()
reads the rest of the stream and calling it again returns nothing because stream is already at the end. You'd have to rewind the stream between those calls.You can't. One workaround might be to generate a derived class at runtime and adding the attribute, although this is probably bit of an overkill.
@ is used as a prefix denoting stored procedure and function parameter names, and also variable names
if you want to use it in all of your classes you can use:
public var yourVariable = "something"
if you want to use just in one class you can use :
var yourVariable = "something"
Use empty
(it checks both nullness and emptiness) and group the nested ternary expression by parentheses (EL is in certain implementations/versions namely somewhat problematic with nested ternary expressions). Thus, so:
styleClass="#{empty obj.validationErrorMap ? ' ' :
(obj.validationErrorMap.contains('key') ? 'highlight_field' : 'highlight_row')}"
If still in vain (I would then check JBoss EL configs), use the "normal" EL approach:
styleClass="#{empty obj.validationErrorMap ? ' ' :
(obj.validationErrorMap['key'] ne null ? 'highlight_field' : 'highlight_row')}"
Update: as per the comments, the Map
turns out to actually be a List
(please work on your naming conventions). To check if a List
contains an item the "normal" EL way, use JSTL fn:contains
(although not explicitly documented, it works for List
as well).
styleClass="#{empty obj.validationErrorMap ? ' ' :
(fn:contains(obj.validationErrorMap, 'key') ? 'highlight_field' : 'highlight_row')}"

For anyone that this might be handy for, here is a jQuery dependent function I had success with for applying a CSS animation via a CSS class, then getting a callback from afterwards. It may not work perfectly since I had it being used in a Backbone.js App, but maybe useful.
var cssAnimate = function(cssClass, callback) {
var self = this;
// Checks if correct animation has ended
var setAnimationListener = function() {
self.one(
"webkitAnimationEnd oanimationend msAnimationEnd animationend",
function(e) {
if(
e.originalEvent.animationName == cssClass &&
e.target === e.currentTarget
) {
callback();
} else {
setAnimationListener();
}
}
);
}
self.addClass(cssClass);
setAnimationListener();
}
I used it kinda like this
cssAnimate.call($("#something"), "fadeIn", function() {
console.log("Animation is complete");
// Remove animation class name?
});
Original idea from http://mikefowler.me/2013/11/18/page-transitions-in-backbone/
And this seems handy: http://api.jqueryui.com/addClass/
Update
After struggling with the above code and other options, I would suggest being very cautious with any listening for CSS animation ends. With multiple animations going on, this can get messy very fast for event listening. I would strongly suggest an animation library like GSAP for every animation, even the small ones.
You can use the lsvirtualenv
, in which you have two options "long" or "brief":
"long" option is the default one, it searches for any hook you may have around this command and executes it, which takes more time.
"brief" just take the virtualenvs names and prints it.
brief usage:
$ lsvirtualenv -b
long usage:
$ lsvirtualenv -l
if you don't have any hooks, or don't even know what i'm talking about, just use "brief".
I use the following:
Function GetProgramOutput([string]$exe, [string]$arguments)
{
$process = New-Object -TypeName System.Diagnostics.Process
$process.StartInfo.FileName = $exe
$process.StartInfo.Arguments = $arguments
$process.StartInfo.UseShellExecute = $false
$process.StartInfo.RedirectStandardOutput = $true
$process.StartInfo.RedirectStandardError = $true
$process.Start()
$output = $process.StandardOutput.ReadToEnd()
$err = $process.StandardError.ReadToEnd()
$process.WaitForExit()
$output
$err
}
$exe = "C:\Program Files\7-Zip\7z.exe"
$arguments = "i"
$runResult = (GetProgramOutput $exe $arguments)
$stdout = $runResult[-2]
$stderr = $runResult[-1]
[System.Console]::WriteLine("Standard out: " + $stdout)
[System.Console]::WriteLine("Standard error: " + $stderr)
I know it sounds weird, but I'm pretty sure this is your problem:
Somewhere in MyGui.java you're using a generic collection without specifying the type. For example if you're using an ArrayList somewhere, you are doing this:
List list = new ArrayList();
When you should be doing this:
List<String> list = new ArrayList<String>();

It seems that the most common method of achieving this is to draw a GPolygon with enough points to simulate a circle. The example you referenced uses this method. This page has a good example - look for the function drawCircle in the source code.
I think your assignment is backwards:
a[i] = b[i];
should be:
b[i] = a[i];
I had the same problem with localhost
in the source URL.
I resolved with 127.0.0.1

To build a result string exactly in the format you show, you can use this:
var sList = "";
$('input[type=checkbox]').each(function () {
sList += "(" + $(this).val() + "-" + (this.checked ? "checked" : "not checked") + ")";
});
console.log (sList);
However, I would agree with @SLaks, I think you should re-consider the structure into which you will store this in your database.
EDIT: Sorry, I mis-read the output format you were looking for. Here is an update:
var sList = "";
$('input[type=checkbox]').each(function () {
var sThisVal = (this.checked ? "1" : "0");
sList += (sList=="" ? sThisVal : "," + sThisVal);
});
console.log (sList);

you can set the dataset to grid as follows:
//assuming your dataset object is ds
datagridview1.datasource= ds;

tablename is the name of the table, which you want to show on the grid.

Here is a walkthrough, Using PostgreSQL in your C# (.NET) application (An introduction):
In this article, I would like to show you the basics of using a PostgreSQL database in your .NET application. The reason why I'm doing this is the lack of PostgreSQL articles on CodeProject despite the fact that it is a very good RDBMS. I have used PostgreSQL back in the days when PHP was my main programming language, and I thought.... well, why not use it in my C# application.
Other than that you will need to give us some specific problems that you are having so that we can help diagnose the problem.
Quick Answer:
foreach (var process in Process.GetProcessesByName("whatever"))
{
process.Kill();
}
(leave off .exe from process name)
Create mysql connection with following parameter. "'raise_on_warnings': False". It will ignore the warning. e.g.
config = {'user': 'user','password': 'passwd','host': 'localhost','database': 'db', 'raise_on_warnings': False,}
cnx = mysql.connector.connect(**config)
You probably want the isinstance
builtin function:
self.data = data if isinstance(data, list) else self.parse(data)
This worked for me. Pseudocode:
// screen width and height
scr = {w:document.documentElement.clientWidth,h:document.documentElement.clientHeight}
canvas.width = scr.w
canvas.height = scr.h
Also, like devyn said, you can replace "document.documentElement.client" with "inner" for both the width and height:
**document.documentElement.client**Width
**inner**Width
**document.documentElement.client**Height
**inner**Height
and it still works.
The error comes when you try to call sum(x)
and x
is a factor.
What that means is that one of your columns, though they look like numbers are actually factors (what you are seeing is the text representation)
simple fix, convert to numeric. However, it needs an intermeidate step of converting to character first. Use the following:
family[, 1] <- as.numeric(as.character( family[, 1] ))
family[, 3] <- as.numeric(as.character( family[, 3] ))
For a detailed explanation of why the intermediate as.character
step is needed, take a look at this question: How to convert a factor to integer\numeric without loss of information?
You can't use string.replace...as one string is assigned you cannot manipulate. For that, we use string builder. Here is my example. In the HTML page I add [Name] which is replaced by Name. Make sure [Name] is unique or you can give any unique name:
string Name = txtname.Text;
string contents = File.ReadAllText(Server.MapPath("~/Admin/invoice.html"));
StringBuilder builder = new StringBuilder(contents);
builder.Replace("[Name]", Name);
StringReader sr = new StringReader(builder.ToString());
View the Inner Exception of the exception to get a more specific error message.
One way to view the Inner Exception would be to catch the exception, and put a breakpoint on it. Then in the Locals window: select the Exception variable > InnerException > Message
And/Or just write to console:
catch (Exception e)
{
Console.WriteLine(e.InnerException.Message);
}
The specific value in your database isn't what you should be focusing on. This is likely the result of an attacker fuzzing your system to see if it is vulnerable to a set of standard attacks, instead of a targeted attack exploiting a known vulnerability.
You should instead focus on ensuring that your application is secure against these types of attacks; OWASP is a good resource for this.
If you're using parameterized queries to access the database, then you're secure against Sql injection, unless you're using dynamic Sql in the backend as well.
If you're not doing this, you're vulnerable and you should resolve this immediately.
Also, you should consider performing some sort of validation of e-mail addresses.
That is not possible du to the Box Model. However you could use a workaround with css3's border-image, or border-color in general css.
However im unsure whether you may have a problem with resetting. Some browsers do set a margin to html as well. See Eric Meyers Reset CSS for more!
html{margin:0;padding:0;}
Increasing Java Heap unfairly eats deficit mobile resurces. Sometimes it is sufficient to just wait for garbage collector and then resume your operations after heap space is reduced. Use this static method then.
Clear:both gives you that space between them.
For example your code:
<div style="float:left">Hello</div>
<div style="float:right">Howdy dere pardner</div>
Will currently display as :
Hello ................... Howdy dere pardner
If you add the following to above snippet,
<div style="clear:both"></div>
In between them it will display as:
Hello ................
Howdy dere pardner
giving you that space between hello and Howdy dere pardner.

I know this is an old question, but since the other answers all
I thought I'd add a "pure" option which only requires datetime operations and works with SQL Server 2005+:
SELECT DATEADD(dd, -DATEDIFF(dd, 0, mydatetime), mydatetime)
This calculates the difference (in whole days) between date zero (1900-01-01) and the given date and then subtracts that number of days from the given date, thereby setting its date component to zero.
You can use one of several available Date formatters. Since this falls within the JavaScript specification, it will be available in both browser and server-side modes.
objDate.toString().split(" ")[1]; // gives short name, unsure about locale
objDate.toLocaleDateString.split(" ")[0]; // gives long name
e.g.
js> objDate = new Date(new Date() - 9876543210)
Mon Feb 04 2013 12:37:09 GMT-0800 (PST)
js> objDate.toString().split(" ")[1]
Feb
js> objDate.toLocaleString().split(" ")[0]
February

Here is a more efficient version which uses on
for all contenteditables. It's based off the top answers here.
$('body').on('focus', '[contenteditable]', function() {
const $this = $(this);
$this.data('before', $this.html());
}).on('blur keyup paste input', '[contenteditable]', function() {
const $this = $(this);
if ($this.data('before') !== $this.html()) {
$this.data('before', $this.html());
$this.trigger('change');
}
});
The project is here: https://github.com/balupton/html5edit
Almost everything in EC2 is multi-tenant. What the network performance indicates is what priority you will have compared with other instances sharing the same infrastructure.
If you need a guaranteed level of bandwidth, then EC2 will likely not work well for you.
Peer dependency warnings, more often than not, can be ignored. The only time you will want to take action is if the peer dependency is missing entirely, or if the version of a peer dependency is higher than the version you have installed.
Let's take this warning as an example:
npm WARN @angular/[email protected] requires a peer of @angular/[email protected] but none is installed. You must install peer dependencies yourself.
With Angular, you would like the versions you are using to be consistent across all packages. If there are any incompatible versions, change the versions in your package.json, and run npm install
so they are all synced up. I tend to keep my versions for Angular at the latest version, but you will need to make sure your versions are consistent for whatever version of Angular you require (which may not be the most recent).
In a situation like this:
npm WARN [email protected] requires a peer of @angular/core@^2.4.0 || ^4.0.0 but none is installed. You must install peer dependencies yourself.
If you are working with a version of Angular that is higher than 4.0.0, then you will likely have no issues. Nothing to do about this one then. If you are using an Angular version under 2.4.0, then you need to bring your version up. Update the package.json, and run npm install
, or run npm install
for the specific version you need. Like this:
npm install @angular/[email protected] --save
You can leave out the --save
if you are running npm 5.0.0 or higher, that version saves the package in the dependencies section of the package.json automatically.
In this situation:
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: [email protected] (node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
You are running Windows, and fsevent requires OSX. This warning can be ignored.
Hope this helps, and have fun learning Angular!
If you have a lot of files to review, you can use this tool: https://www.mannaz.at/codebase/utf-byte-order-mark-bom-remover/

It help me to clean a system, with MVC in CakePhp, as i work in Linux, Windows, with different tools.. in some files my design was break.. so after checkin in Chrome with debug tool find the  error
You need only to write:
GRANT DBA TO NewDBA;
Because this already makes the user a DB Administrator
You should set the src
attribute after the onload
event, f.ex:
el.onload = function() { //...
el.src = script;
You should also append the script to the DOM before attaching the onload
event:
$body.append(el);
el.onload = function() { //...
el.src = script;
Remember that you need to check readystate
for IE support. If you are using jQuery, you can also try the getScript()
method: http://api.jquery.com/jQuery.getScript/
This version will go through all of the stylesheets on a page. For my needs, the styles were usually in the 2nd to last of the 20+ stylesheets, so I check them backwards.
var getStyle = function(className){
var x, sheets,classes;
for( sheets=document.styleSheets.length-1; sheets>=0; sheets-- ){
classes = document.styleSheets[sheets].rules || document.styleSheets[sheets].cssRules;
for(x=0;x<classes.length;x++) {
if(classes[x].selectorText===className) {
return (classes[x].cssText ? classes[x].cssText : classes[x].style.cssText);
}
}
}
return false;
};
Is it possible to have more than one student in a class having same Roll/Id no? In HTMLid
attribute is like so. You may use same class for them. e.g:
<div class="a b c"></div>
<div class="a b c d"></div>
And so on.
Fetch all at once =
List<Integer> list = null;
if(map!= null)
{
list = new ArrayList<Integer>(map.values());
}
For Storing =
if(map!= null)
{
list = map.get(keyString);
if(list == null)
{
list = new ArrayList<Integer>();
}
list.add(value);
map.put(keyString,list);
}
If you can use inline styling, you can set the left and right padding on each td
.. Or you use an extra td
between columns and set a number of non-breaking spaces as @rene kindly suggested.
Both are pretty ugly ;p css ftw
@swpd's answer improved
I use ,
as a leader key and ,a
shortcut does the trick
Add this line if you prefer ,a
shortcut
map <Leader>a :%y+<CR>
I use Ctrl y
shortcut to copy
vmap <C-y> y:call system("xclip -i -selection clipboard", getreg("\""))<CR>:call system("xclip -i", getreg("\""))<CR>
And ,v
to paste
nmap <Leader>v :call setreg("\"",system("xclip -o -selection clipboard"))<CR>p
Before using this you have to install xclip
$ sudo apt-get install xclip
Edit: When you use :%y+
, it can be only pasted to Vim vim Ctrl+Insert
shortcut.
And
map <C-a> :%y+<Esc>
is not conflicting any settings in my Vimrc.
or you can give specific offsets to make button position where you want simply with bootstrap grid system,
<div class="col-md-offset-4 col-md-2 col-md-offset-5">
<input type="submit" class="btn btn-block" value="submit"/>
this way, also let you specify button size if you set btn-block. sure, this will only work md size range, if you want to set other sizes too, use xs,sm,lg.
Use the %
wildcard, which matches any number of characters.
SELECT * FROM Accounts WHERE Username LIKE '%query%'
If anyone else stumbles onto this page from google like I did:
use putty (putty.exe) to sign into your server and install curl using this command :
sudo apt-get install php5-curl
Make sure curl is enabled in the php.ini file. For me it's in /etc/php5/apache2/php.ini, if you can't find it, this line might be in /etc/php5/conf.d/curl.ini. Make sure the line :
extension=curl.so
is not commented out then restart apache, so type this into putty:
sudo /etc/init.d/apache2 restart
Info for install from https://askubuntu.com/questions/9293/how-do-i-install-curl-in-php5, to check if it works this stack overflow might help you: Detect if cURL works?
Can you output that data in the cells as you are creating the table?
so your table would look like this:
<table>
<thead>...</thead>
<tbody>
<tr><td data-row='1' data-column='1'>value</td>
<td data-row='1' data-column='2'>value</td>
<td data-row='1' data-column='3'>value</td></tr>
<tbody>
</table>
then it would be a simple matter
$("td").click(function(event) {
var row = $(this).attr("data-row");
var col = $(this).attr("data-col");
}
The Data Export function in MySQL Workbench allows 2 of the 3 ways. There's a checkbox Skip Table Data (no-data)
on the export page which allows to either dump with or without data. Just dumping the data without meta data is not supported.
Since you're dealing with values that are just supposed to be boolean anyway, just use ==
and convert the logical response to as.integer
:
df <- data.frame(col = c("true", "true", "false"))
df
# col
# 1 true
# 2 true
# 3 false
df$col <- as.integer(df$col == "true")
df
# col
# 1 1
# 2 1
# 3 0
::
Lets you access a constant, module, or class defined inside another class or module. It is used to provide namespaces so that method and class names don't conflict with other classes by different authors.
When you see ActiveRecord::Base
in Rails it means that Rails has something like
module ActiveRecord
class Base
end
end
i.e. a class called Base
inside a module ActiveRecord
which is then referenced as ActiveRecord::Base
(you can find this in the Rails source in activerecord-n.n.n/lib/active_record/base.rb)
A common use of :: is to access constants defined in modules e.g.
module Math
PI = 3.141 # ...
end
puts Math::PI
The ::
operator does not allow you to bypass visibility of methods marked private or protected.
Sander ,I believe you are trying to show the view blocked by the soft keyboard. Try this http://android-developers.blogspot.com/2009/04/updating-applications-for-on-screen.html.

print the full path
echo $dir
To add to Phimueme's answer above, if your string is always two characters, then you can build a 16-bit int out of the two 8-bit characters - and switch on that (to avoid nested switch/case statements).
You are looking for the jQuery extend method. This will allow you to add other members to your already created JS object.
I wouldn't want any public site that I developed to depend on any external site, and thus, I'd host jQuery myself.
Are you willing to have an outage on your site when the other (Google, jquery.com, etc.) goes down? Less dependencies is the key.
My answer is intended for comment though but since i havent got enough reputation, i think it will still be relevant as an answer and help some one.
I find datatable
in library DT
robust to handle rownames
, and columnames
Library DT
datatable(df, rownames = FALSE) # no row names
refer to https://rstudio.github.io/DT/ for usage scenarios
Firstly, on Unix you use mount
, not ls /mnt
: many things are not mounted in /mnt
.
Anyhow, there's the mountvol
DOS command, which continues to work in Powershell, and there's the Powershell-specific Get-PSDrive
.
Chiming in to recommend the use of the xmltodict library. It handled your xml text pretty well and I've used it for ingesting an xml file with almost a million records.
git log --oneline --decorate --all --graph
A visual tree with branch names included.
Use this to add it as an alias
git config --global alias.tree "log --oneline --decorate --all --graph"
You call it with
git tree
Today, in the year 2016, it is save to use document.querySelector
without knowing the ID (especially if you have more than 2 radio buttons):
document.querySelector("input[name=main-categories]:checked").value
I have been using MongoDB .NET driver for a little over a month now. If I were to do it using .NET driver, I would use Update method on the collection object. First, I will construct a query that will get me all the documents I am interested in and do an Update on the fields I want to change. Update in Mongo only affects the first document and to update all documents resulting from the query one needs to use 'Multi' update flag. Sample code follows...
var collection = db.GetCollection("Foo");
var query = Query.GTE("No", 1); // need to construct in such a way that it will give all 20K //docs.
var update = Update.Set("timestamp", datetime.UtcNow);
collection.Update(query, update, UpdateFlags.Multi);
