Kakfa version check can be done with confluent
utility which comes by default with Confluent platform(confluent
utility can be added to cluster separately as well - credits cricket_007).
${confluent.home}/bin/confluent version kafka
Checking the version of other Confluent platform components like ksql schema-registry and connect
[confluent-4.1.0]$ ./bin/confluent version kafka
1.1.0-cp1
[confluent-4.1.0]$ ./bin/confluent version connect
4.1.0
[confluent-4.1.0]$ ./bin/confluent version schema-registry

This is a follow up to my previous answer and contains C++11 related material..
Pre-requisites : An elementary knowledge of Relations (Mathematics).
Yes! This is very true.
Sequence Points have been replaced by Sequenced Before and Sequenced After (and Unsequenced and Indeterminately Sequenced) relations in C++11.
Sequenced Before(§1.9/13) is a relation which is:
between evaluations executed by a single thread and induces a strict partial order1
Formally it means given any two evaluations(See below) A
and B
, if A
is sequenced before B
, then the execution of A
shall precede the execution of B
. If A
is not sequenced before B
and B
is not sequenced before A
, then A
and B
are unsequenced 2.
Evaluations A
and B
are indeterminately sequenced when either A
is sequenced before B
or B
is sequenced before A
, but it is unspecified which3.
[NOTES]
1 : A strict partial order is a binary relation "<"
over a set P
which is asymmetric
, and transitive
, i.e., for all a
, b
, and c
in P
, we have that:
........(i). if a < b then ¬ (b < a) (asymmetry
);
........(ii). if a < b and b < c then a < c (transitivity
).
2 : The execution of unsequenced evaluations can overlap.
3 : Indeterminately sequenced evaluations cannot overlap, but either could be executed first.
In C++11, evaluation of an expression (or a sub-expression) in general includes:
value computations (including determining the identity of an object for glvalue evaluation and fetching a value previously assigned to an object for prvalue evaluation) and
initiation of side effects.
Now (§1.9/14) says:
Every value computation and side effect associated with a full-expression is sequenced before every value computation and side effect associated with the next full-expression to be evaluated.
Trivial example:
int x;
x = 10;
++x;
Value computation and side effect associated with ++x
is sequenced after the value computation and side effect of x = 10;
Yes! Right.
In (§1.9/15) it has been mentioned that
Except where noted, evaluations of operands of individual operators and of subexpressions of individual expressions are unsequenced4.
For example :
int main()
{
int num = 19 ;
num = (num << 3) + (num >> 3);
}
+
operator are unsequenced relative to each other.<<
and >>
operators are unsequenced relative to each other.4: In an expression that is evaluated more than once during the execution of a program, unsequenced and indeterminately sequenced evaluations of its subexpressions need not be performed consistently in different evaluations.
(§1.9/15) The value computations of the operands of an operator are sequenced before the value computation of the result of the operator.
That means in x + y
the value computation of x
and y
are sequenced before the value computation of (x + y)
.
More importantly
(§1.9/15) If a side effect on a scalar object is unsequenced relative to either
(a) another side effect on the same scalar object
or
(b) a value computation using the value of the same scalar object.
the behaviour is undefined.
Examples:
int i = 5, v[10] = { };
void f(int, int);
i = i++ * ++i; // Undefined Behaviour
i = ++i + i++; // Undefined Behaviour
i = ++i + ++i; // Undefined Behaviour
i = v[i++]; // Undefined Behaviour
i = v[++i]: // Well-defined Behavior
i = i++ + 1; // Undefined Behaviour
i = ++i + 1; // Well-defined Behaviour
++++i; // Well-defined Behaviour
f(i = -1, i = -1); // Undefined Behaviour (see below)
When calling a function (whether or not the function is inline), every value computation and side effect associated with any argument expression, or with the postfix expression designating the called function, is sequenced before execution of every expression or statement in the body of the called function. [Note: Value computations and side effects associated with different argument expressions are unsequenced. — end note]
Expressions (5)
, (7)
and (8)
do not invoke undefined behaviour. Check out the following answers for a more detailed explanation.

Without For loop:
Dim newColumn As New Data.DataColumn("Foo", GetType(System.String))
newColumn.DefaultValue = "Your DropDownList value"
table.Columns.Add(newColumn)
C#:
System.Data.DataColumn newColumn = new System.Data.DataColumn("Foo", typeof(System.String));
newColumn.DefaultValue = "Your DropDownList value";
table.Columns.Add(newColumn);
In C language, objects with static storage duration have to be initialized with constant expressions, or with aggregate initializers containing constant expressions.
A "large" object is never a constant expression in C, even if the object is declared as const
.
Moreover, in C language, the term "constant" refers to literal constants (like 1
, 'a'
, 0xFF
and so on), enum members, and results of such operators as sizeof
. Const-qualified objects (of any type) are not constants in C language terminology. They cannot be used in initializers of objects with static storage duration, regardless of their type.
For example, this is NOT a constant
const int N = 5; /* `N` is not a constant in C */
The above N
would be a constant in C++, but it is not a constant in C. So, if you try doing
static int j = N; /* ERROR */
you will get the same error: an attempt to initialize a static object with a non-constant.
This is the reason why, in C language, we predominantly use #define
to declare named constants, and also resort to #define
to create named aggregate initializers.
Only such dialog is FileDialog. Its part of WinForms, but its actually only wrapper around WinAPI standard OS file dialog. And I don't think it is ugly, its actually part of OS, so it looks like OS it is run on.
Other way, there is nothing to help you with. You either need to look for 3rd party implementation, either free (and I don't think there are any good) or paid.
l = [1, 2, 3, 4, 5]
del l[0:3] # Here 3 specifies the number of items to be deleted.
This is the code if you want to delete a number of items from the list. You might as well skip the zero before the colon. It does not have that importance. This might do as well.
l = [1, 2, 3, 4, 5]
del l[:3] # Here 3 specifies the number of items to be deleted.
Using dep.exe you can list out all the nested dependencies of an entire folder. Combined with unix tools like grep or awk, it can help you to solve your problem
$ dep | awk '{ print $1 " " $2; print $4 " " $5 }' | awk '{ if (length(versions[$1]) == 0) versions[$1] = $2; if (versions[$1] != $2) errors[$1] = $1; } END{ for(e in errors) print e } '
System.Web.Http
This obscure command line runs dep.exe then pipes the output twice to awk to
$ dep myproject/bin | grep -i System\.Web\.Http
MyProject-1.0.0.0 >> System.Web.Http.Web-5.2.3.0 2 ( FooLib-1.0.0.0 )
MyProject-1.0.0.0 >> System.Web.Http.Web-4.0.0.0 2 ( BarLib-1.0.0.0 )
FooLib-1.0.0.0 > System.Web.Http.Web-5.2.3.0 1
BarLib-1.0.0.0 > System.Web.Http.Web-4.0.0.0 1
In this example, the tool would show you that System.Web.Http 5.2.3 comes from your dependency to FooLib whereas the version 4.0.0 comes from BarLib.
Then you have the choice between
If you don't have a unix type shell you'll need to download one before being able to run awk
and grep
. Try one of the following
Compilr seems to be going in that direction: http://compilr.com/teachers
Other type of format :
$headers[] = 'Accept: application/json';
$headers[] = 'Content-Type: application/json';
$headers[] = 'Content-length: 0';
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, $headers);
This is the normal behavior and the reason is that your sqlCommandHandlerService.persist
method needs a TX when being executed (because it is marked with @Transactional
annotation). But when it is called inside processNextRegistrationMessage
, because there is a TX available, the container doesn't create a new one and uses existing TX. So if any exception occurs in sqlCommandHandlerService.persist
method, it causes TX to be set to rollBackOnly
(even if you catch the exception in the caller and ignore it).
To overcome this you can use propagation levels for transactions. Have a look at this to find out which propagation best suits your requirements.
Well after a colleague came to me with a couple of questions about a similar situation, I feel this needs a bit of clarification.
Although propagations solve such issues, you should be VERY careful about using them and do not use them unless you ABSOLUTELY understand what they mean and how they work. You may end up persisting some data and rolling back some others where you don't expect them to work that way and things can go horribly wrong.
---- Remove Constraint ----
EXEC sp_MSForEachTable "ALTER TABLE ? NOCHECK CONSTRAINT all"
---- Delete Data ----
EXEC sp_MSForEachTable "DELETE FROM ?"
---- Add Constraint ----
EXEC sp_MSForEachTable "ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all"
---- Reset Identity value ----
EXEC sp_MSForEachTable "DBCC CHECKIDENT ( '?', RESEED, 0)"
Since C++ 17 (VS2015) you can use the standard for read-write locks:
#include <shared_mutex>
typedef std::shared_mutex Lock;
typedef std::unique_lock< Lock > WriteLock;
typedef std::shared_lock< Lock > ReadLock;
Lock myLock;
void ReadFunction()
{
ReadLock r_lock(myLock);
//Do reader stuff
}
void WriteFunction()
{
WriteLock w_lock(myLock);
//Do writer stuff
}
For older version, you can use boost with the same syntax:
#include <boost/thread/locks.hpp>
#include <boost/thread/shared_mutex.hpp>
typedef boost::shared_mutex Lock;
typedef boost::unique_lock< Lock > WriteLock;
typedef boost::shared_lock< Lock > ReadLock;
#many .more.selectors h4 + p { ... }
This is called the adjacent sibling selector.
This is Similar to what Meritt has posted earlier. just posting the complete code
string sJSON;
Dictionary<string, string> aa1 = new Dictionary<string, string>();
aa1.Add("one", "1"); aa1.Add("two", "2"); aa1.Add("three", "3");
Console.Write("JSON form of Person object: ");
sJSON = WriteFromObject(aa1);
Console.WriteLine(sJSON);
Dictionary<string, string> aaret = new Dictionary<string, string>();
aaret = ReadToObject<Dictionary<string, string>>(sJSON);
public static string WriteFromObject(object obj)
{
byte[] json;
//Create a stream to serialize the object to.
using (MemoryStream ms = new MemoryStream())
{
// Serializer the object to the stream.
DataContractJsonSerializer ser = new DataContractJsonSerializer(obj.GetType());
ser.WriteObject(ms, obj);
json = ms.ToArray();
ms.Close();
}
return Encoding.UTF8.GetString(json, 0, json.Length);
}
// Deserialize a JSON stream to object.
public static T ReadToObject<T>(string json) where T : class, new()
{
T deserializedObject = new T();
using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(json)))
{
DataContractJsonSerializer ser = new DataContractJsonSerializer(deserializedObject.GetType());
deserializedObject = ser.ReadObject(ms) as T;
ms.Close();
}
return deserializedObject;
}
I've created a custom PagerAdapters library to change items in PagerAdapters dynamically.
You can change items dynamically like following by using this library.
@Override
protected void onCreate(Bundle savedInstanceState) {
/** ... **/
adapter = new MyStatePagerAdapter(getSupportFragmentManager()
, new String[]{"1", "2", "3"});
((ViewPager)findViewById(R.id.view_pager)).setAdapter(adapter);
adapter.add("4");
adapter.remove(0);
}
class MyPagerAdapter extends ArrayViewPagerAdapter<String> {
public MyPagerAdapter(String[] data) {
super(data);
}
@Override
public View getView(LayoutInflater inflater, ViewGroup container, String item, int position) {
View v = inflater.inflate(R.layout.item_page, container, false);
((TextView) v.findViewById(R.id.item_txt)).setText(item);
return v;
}
}
Thils library also support pages created by Fragments.
This works for me:
<?if(isset($_POST['oldPost'])):?>
<form method="post" id="resetPost"></form>
<script>$("#resetPost").submit()</script>
<?endif?>
I was having similar issue because of a different reason:

I did something similar to this for http://bookmarkchamp.com - there I wanted to detect when a user copied something into an HTML field. The implementation I came up with was to check the field constantly to see if at any time there was suddenly a whole lot of text in there.
In other words: if once milisecond ago there was no text, and now there are more than 5 chars... then the user probably pasted something in the field.
If you want to see this working in Bookmarkchamp (you need to be registered), paste a URL into the URL field (or drag and drop a URL in there).
And if you just want to create the constraint on its own, you can use ALTER TABLE
alter table MyTable
add constraint MyTable_MyColumn_FK FOREIGN KEY ( MyColumn ) references MyOtherTable(PKColumn)
I wouldn't recommend the syntax mentioned by Sara Chipps for inline creation, just because I would rather name my own constraints.
Note: z-index only works on positioned elements (position:absolute
, position:relative
, or position:fixed
). Use one of those.
length = 4
string = "abcdefgh"
str_dict = [ o for o in string ]
parts = [ ''.join( str_dict[ (j * length) : ( ( j + 1 ) * length ) ] ) for j in xrange(len(string)/length )]
Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.
Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe
, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.
A property is in the DOM; an attribute is in the HTML that is parsed into the DOM.
If you change an attribute, the change will be reflected in the DOM (sometimes with a different name).
Example: Changing the class
attribute of a tag will change the className
property of that tag in the DOM.
If you have no attribute on a tag, you still have the corresponding DOM property with an empty or a default value.
Example: While your tag has no class
attribute, the DOM property className
does exist with a empty string value.
edit
If you change the one, the other will be changed by a controller, and vice versa. This controller is not in jQuery, but in the browser's native code.
Following @acdcjunior answer, this is how I implemented it
service:
get(url, params): Promise<Object> {
return this.sendRequest(this.baseUrl + url, 'get', null, params)
.map((res) => {
return res as Object
}).catch((e) => {
return Observable.of(e);
})
.toPromise();
}
caller:
this.dataService.get(baseUrl, params)
.then((object) => {
if(object['name'] === 'HttpErrorResponse') {
this.error = true;
//or any handle
} else {
this.myObj = object as MyClass
}
});
java_home environment variable should point to the location of the proper version of java installation directory, so that tomcat starts with the right version. for example it you built the project with java 1.7 , then make sure that JAVA_HOME environment variable points to the jdk 1.7 installation directory in your machine.
I had same problem , when i deploy the war in tomcat and run, the link throws the error. But pointing the variable - JAVA_HOME to jdk 1.7 resolved the issue, as my war file was built in java 1.7 environment.
Was this "cheating"? I just made my Configuration in the Startup class static, and then I can access it from anywhere else:

.SetBasePath(env.ContentRootPath)
.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
.AddEnvironmentVariables();
Configuration = builder.Build();
}
public static IConfiguration Configuration { get; set; }

This is the best solution I have found till now. Updates the ngModel
on blur
and debounce
import { Directive, Input, Output, EventEmitter,ElementRef } from '@angular/core';
import { NgControl, NgModel } from '@angular/forms';
import 'rxjs/add/operator/debounceTime';
import 'rxjs/add/operator/distinctUntilChanged';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/fromEvent';
import 'rxjs/add/operator/map';
@Directive({
selector: '[ngModel][debounce]',
})
export class DebounceDirective {
@Output()
public onDebounce = new EventEmitter<any>();
@Input('debounce')
public debounceTime: number = 500;
private isFirstChange: boolean = true;
constructor(private elementRef: ElementRef, private model: NgModel) {
}
ngOnInit() {
const eventStream = Observable.fromEvent(this.elementRef.nativeElement, 'keyup')
.map(() => {
return this.model.value;
})
.debounceTime(this.debounceTime);
this.model.viewToModelUpdate = () => {};
eventStream.subscribe(input => {
this.model.viewModel = input;
this.model.update.emit(input);
});
}
}
as borrowed from https://stackoverflow.com/a/47823960/3955513
Then in HTML:
<input [(ngModel)]="hero.name"
[debounce]="3000"
(blur)="hero.name = $event.target.value"
(ngModelChange)="onChange()"
placeholder="name">
On blur
the model is explicitly updated using plain javascript.

Therefore, the following works for me
$qb->select('c')
->innerJoin('c.phones', 'p', 'WITH', 'p.phone = :phone')
->where('c.username = :username');
or
$qb->select('c')
->innerJoin('c.phones', 'p', Join::WITH, $qb->expr()->eq('p.phone', ':phone'))
->where('c.username = :username');
You should be able to use forward slashes in Java to refer to file locations.
The BufferedReader class is used for wrapping other file readers whos read method may not be very efficient. A more detailed description can be found in the Java APIs.
Toolkit's use of BufferedReader is probably what you need.
Just change the indexes. i and j....in the loop, plus if you're dealing with Strings you have to use concat and initialize the variable to an empty Strong otherwise you'll get an exception.
String string="";
for (int i = 0; i<array.length; i++){
for (int j = 0; j<array[i].length; j++){
string = string.concat(array[j][i]);
}
}
System.out.println(string)
In order to determine the aspect ratio, you need to have a ratio to aim for.
function getHeight(length, ratio) {
var height = ((length)/(Math.sqrt((Math.pow(ratio, 2)+1))));
return Math.round(height);
}
function getWidth(length, ratio) {
var width = ((length)/(Math.sqrt((1)/(Math.pow(ratio, 2)+1))));
return Math.round(width);
}
In this example I use 16:10
since this the typical monitor aspect ratio.
var ratio = (16/10);
var height = getHeight(300,ratio);
var width = getWidth(height,ratio);
console.log(height);
console.log(width);
Results from above would be 147
and 300
When you have opened a folder in a workspace you can do Ctrl+P (Cmd+P on Mac) and start typing the filename, or extension to filter the list of filenames
if you have:
You can type css
and press enter and it will open the page.css
. If you type .ts
the list is filtered and contains two items.
String are immutable, that's why questionText.replace(/[0-9]/g, '');
on it's own does work, but it doesn't change the questionText-string. You'll have to assign the result of the replacement to another String-variable or to questionText itself again.
var cleanedQuestionText = questionText.replace(/[0-9]/g, '');
or in 1 go (using \d+
, see Kobi's answer):
questionText = ("1 ding ?").replace(/\d+/g,'');
and if you want to trim the leading (and trailing) space(s) while you're at it:
questionText = ("1 ding ?").replace(/\d+|^\s+|\s+$/g,'');

I use varargs frequently for outputting to the logs for purposes of debugging.
Pretty much every class in my app has a method debugPrint():
private void debugPrint(Object... msg) {
for (Object item : msg) System.out.print(item);
System.out.println();
}
Then, within methods of the class, I have calls like the following:
debugPrint("for assignment ", hwId, ", student ", studentId, ", question ",
serialNo, ", the grade is ", grade);
When I'm satisfied that my code is working, I comment out the code in the debugPrint() method so that the logs will not contain too much extraneous and unwanted information, but I can leave the individual calls to debugPrint() uncommented. Later, if I find a bug, I just uncomment the debugPrint() code, and all my calls to debugPrint() are reactivated.
Of course, I could just as easily eschew varargs and do the following instead:
private void debugPrint(String msg) {
System.out.println(msg);
}
debugPrint("for assignment " + hwId + ", student " + studentId + ", question "
+ serialNo + ", the grade is " + grade);
However, in this case, when I comment out the debugPrint() code, the server still has to go through the trouble of concatenating all the variables in every call to debugPrint(), even though nothing is done with the resulting string. If I use varargs, however, the server only has to put them in an array before it realizes that it doesn't need them. Lots of time is saved.
You can use the &
operator. Here is the source code:
#include<stdio.h>
#include<stdlib.h>
int main(){
int a[10];
int *p;
printf("%p\n", (void *)a);
printf("%p\n", (void *)(&a+1));
printf("---- diff----\n");
printf("%zu\n", sizeof(a[0]));
printf("The size of array a is %zu\n", ((char *)(&a+1)-(char *)a)/(sizeof(a[0])));
return 0;
};
Here is the sample output
1549216672
1549216712
---- diff----
4
The size of array a is 10
ALTER TABLE DROP FOREIGN KEY fk_name;
ALTER TABLE ADD FOREIGN KEY fk_name(fk_cols)
REFERENCES tbl_name(pk_names) ON DELETE RESTRICT;
Maybe you should try ON DELETE CASCADE
The libraries mentioned in other answers would be fine solutions, but if you already happen to be digging through real-world html in your project, the Jsoup

I had it on the Makefile
MAPS+=reverse/db.901:550:2001.ip6.arpa
lastserial: ${MAPS}
./updateser ${MAPS}
It's because of the :
in the file name.
I solved this with
-------- notice / / v v MAPS+=reverse/db.901\:550\:2001.ip6.arpa lastserial: ${MAPS} ./updateser ${MAPS}
I would use expr match
instead of =~
:
expr match "$date" "[0-9]\{8\}" >/dev/null && echo yes
This is better than the currently accepted answer of using =~
because =~
will also match empty strings, which IMHO it shouldn't. Suppose badvar
is not defined, then [[ "1234" =~ "$badvar" ]]; echo $?
gives (incorrectly) 0
, while expr match "1234" "$badvar" >/dev/null ; echo $?
gives correct result 1
.
We have to use >/dev/null
to hide expr match
's output value, which is the number of characters matched or 0 if no match found. Note its output value is different from its exit status. The exit status is 0 if there's a match found, or 1 otherwise.
Generally, the syntax for expr
is:
expr match "$string" "$lead"
Or:
expr "$string" : "$lead"
where $lead
is a regular expression. Its exit status
will be true (0) if lead
matches the leading slice of string
(Is there a name for this?). For example expr match "abcdefghi" "abc"
exits true
, but expr match "abcdefghi" "bcd"
exits false
. (Credit to @Carlo Wood for pointing out this.
Simply convert int
to NSString
use :
int x=10;
NSString *strX=[NSString stringWithFormat:@"%d",x];
Try keydown
instead of keypress
.
The keyboard events occur in this order: keydown
, keyup
, keypress
The problem with backspace probably is, that the browser will navigate back on keyup
and thus your page will not see the keypress
event.
If you want to effect on the menu options for changing the locale immediately.You have to do like this.
//onCreate method calls only once when menu is called first time.
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
//1.Here you can add your locale settings .
//2.Your menu declaration.
}
//This method is called when your menu is opend to again....
@Override
public boolean onMenuOpened(int featureId, Menu menu) {
menu.clear();
onCreateOptionsMenu(menu);
return super.onMenuOpened(featureId, menu);

I'm obviosly not a very good R coder, but if you wanted to do this with ggplot2:
data<- rbind(c(480, 780, 431, 295, 670, 360, 190),
c(720, 350, 377, 255, 340, 615, 345),
c(460, 480, 179, 560, 60, 735, 1260),
c(220, 240, 876, 789, 820, 100, 75))
a <- cbind(data[, 1], 1, c(1:4))
b <- cbind(data[, 2], 2, c(1:4))
c <- cbind(data[, 3], 3, c(1:4))
d <- cbind(data[, 4], 4, c(1:4))
e <- cbind(data[, 5], 5, c(1:4))
f <- cbind(data[, 6], 6, c(1:4))
g <- cbind(data[, 7], 7, c(1:4))
data <- as.data.frame(rbind(a, b, c, d, e, f, g))
colnames(data) <-c("Time", "Type", "Group")
data$Type <- factor(data$Type, labels = c("A", "B", "C", "D", "E", "F", "G"))
library(ggplot2)
ggplot(data = data, aes(x = Type, y = Time, fill = Group)) +
geom_bar(stat = "identity") +
opts(legend.position = "none")
I often use a quick-n-dirty trick to read a fixed number of arguments from the command-line:
[filename] = sys.argv[1:]
in_file = open(filename) # Don't need the "r"
This will assign the one argument to filename
and raise an exception if there isn't exactly one argument.
I think, it is redundant. rs.getObject("ID_PARENT")
should return an Integer
object or null
, if the column value actually was NULL
. So it should even be possible to do something like:
if (rs.next()) {
Integer idParent = (Integer) rs.getObject("ID_PARENT");
if (idParent != null) {
iVal = idParent; // works for Java 1.5+
} else {
// handle this case
}
}
The following function works for textfiles and binary files (returns only position in byte-count though), it does have the benefit to find strings even if they would overlap a line or buffer and would not be found when searching line- or buffer-wise.
def fnd(fname, s, start=0):
with open(fname, 'rb') as f:
fsize = os.path.getsize(fname)
bsize = 4096
buffer = None
if start > 0:
f.seek(start)
overlap = len(s) - 1
while True:
if (f.tell() >= overlap and f.tell() < fsize):
f.seek(f.tell() - overlap)
buffer = f.read(bsize)
if buffer:
pos = buffer.find(s)
if pos >= 0:
return f.tell() - (len(buffer) - pos)
else:
return -1
The idea behind this is:
I used something like this to find signatures of files inside larger ISO9660 files, which was quite fast and did not use much memory, you can also use a larger buffer to speed things up.
System.out
is a PrintStream
, and in itself does not provide any way to modify what gets output. Depending on what is backing that object, you may or may not be able to modify it. For example, if you are redirecting System.out
to a log file, you may be able to modify that file after the fact. If it's going straight to a console, the text will disappear once it reaches the top of the console's buffer, but there's no way to mess with it programmatically.
I'm not sure exactly what you're hoping to accomplish, but you may want to consider creating a proxy PrintStream
to filter messages as they get output, instead of trying to remove them after the fact.
If you can't access the file and your os is any linux distro or mac os x then either of these commands should work:
sudo nano .bashrc
chmod 777 .bashrc
it is worthless

I had a case when I needed to insert children into the modal conditionally. Something like this, bellow.
const [view, setView] = useState(VIEWS.SomeView)
return (
<Modal onClose={onClose}>
{VIEWS.Result === view ? (
<Result onDeny={() => setView(VIEWS.Details)} />
) : VIEWS.Details === view ? (
<Details onDeny={() => setView(VIEWS.Result) /> />
) : null}
</Modal>
)
So !parent.contains(event.target)
doesn't work here, because once you detach children, parent (modal) doesn't contain event.target
anymore.
The solution I had (which works so far and have no any issue) is to write something like this:
const listener = (event: MouseEvent) => {
if (parentNodeRef && !event.path.includes(parentNodeRef)) callback()
}
If parent contained element from already detached tree, it wouldn't fire callback.
EDIT:
event.path
is new and doesn't exit in all browsers yet. Use compoesedPath
instead.
I just written last line as Pause it worked fine with both .bat and .cmd. It will display message also as 'Press any key to continue'.

I think that I also faced this problem, and the best solution I found was to look at my console and figure out the error that was being thrown. So, I read it carefully and found that the problem was that I didn't specify my repo, description, and valid name in my package.json
. I added those pieces of information and everything was okay.
For me the problem was caused by a gradle.properties file in the list of Gradle scripts. It showed as gradle.properties (global) and refered to a file in C:\users\.gradle\gradle.properties. I right-clicked on it and selected delete from the menu to delete it. It deleted the file from the hard disk and my project now builds and runs. I guess that the global file was overwriting something that was used to locate the package android.support
From documentation: https://docs.djangoproject.com/en/1.10/ref/settings/
if DEBUG is False, you also need to properly set the ALLOWED_HOSTS setting. Failing to do so will result in all requests being returned as “Bad Request (400)”.
And from here: https://docs.djangoproject.com/en/1.10/ref/settings/#std:setting-ALLOWED_HOSTS
I am using something like this:
ALLOWED_HOSTS = ['localhost', '127.0.0.1', 'www.mysite.com']
In my case, my array was multidimensional, potentially with arrays as values. So I created this recursive function to blow apart the array completely:
function array2csv($array, &$title, &$data) {
foreach($array as $key => $value) {
if(is_array($value)) {
$title .= $key . ",";
$data .= "" . ",";
array2csv($value, $title, $data);
} else {
$title .= $key . ",";
$data .= '"' . $value . '",';
}
}
}
Since the various levels of my array didn't lend themselves well to a the flat CSV format, I created a blank column with the sub-array's key to serve as a descriptive "intro" to the next level of data. Sample output:
agentid fname lname empid totals sales leads dish dishnet top200_plus top120 latino base_packages
G-adriana ADRIANA EUGENIA PALOMO PAIZ 886 0 19 0 0 0 0 0
You could easily remove that "intro" (descriptive) column, but in my case I had repeating column headers, i.e. inbound_leads, in each sub-array, so that gave me a break/title preceding the next section. Remove:
$title .= $key . ",";
$data .= "" . ",";
after the is_array() to compact the code further and remove the extra column.
Since I wanted both a title row and data row, I pass two variables into the function and upon completion of the call to the function, terminate both with PHP_EOL:
$title .= PHP_EOL;
$data .= PHP_EOL;
Yes, I know I leave an extra comma, but for the sake of brevity, I didn't handle it here.
Wrapping the existing formula in IFERROR will not achieve:
the average of cells that contain non-zero, non-blank values.
I suggest trying:
=if(ArrayFormula(isnumber(K23:M23)),AVERAGEIF(K23:M23,"<>0"),"")
Sub test()
MsgBox Worksheets("sheet_name").Range("A65536").End(xlUp).Row
End Sub
This is looking for a value in column A
because of "A65536"
.
if exist yourfilename (
echo Yes
) else (
echo No
)
Replace yourfilename with the name of your file.
if exist yourfoldername\ (
echo Yes
) else (
echo No
)
Replace yourfoldername with the name of your folder.
A trailing backslash (\
) seems to be enough to distinguish between directories and ordinary files.
If you're willing to run X applications as well - use xpra together with "screen".
if (array_diff($a,$b) == array_diff($b,$a)) {
// Equals
}
if (array_diff($a,$b) != array_diff($b,$a)) {
// Not Equals
}
From my pov it's better to use array_diff than array_intersect because with checks of this nature the differences returned commonly are less than the similarities, this way the bool conversion is less memory hungry.
Edit Note that this solution is for plain arrays and complements the == and === one posted above that is only valid for dictionaries.
Another convenient way to copy the values from src ArrayList to dest Arraylist is as follows:
ArrayList<String> src = new ArrayList<String>();
src.add("test string1");
src.add("test string2");
ArrayList<String> dest= new ArrayList<String>();
dest.addAll(src);
This is actual copying of values and not just copying of reference.
You need to split the line first.
import csv
with open('log.txt', 'r') as in_file:
stripped = (line.strip() for line in in_file)
lines = (line.split(",") for line in stripped if line)
with open('log.csv', 'w') as out_file:
writer = csv.writer(out_file)
writer.writerow(('title', 'intro'))
writer.writerows(lines)
Simpler than I thought. Ctrl + A Followed by Ctrl + H Then Select Regular Expression .*
. Replace \n\n
with \n
. Voila!
A combination of @Jack's answer and @ranierbit's answer should do the trick.
Set the ng build flag for --output-hashing so:
ng build --output-hashing=all
Then add this class either in a service or in your app.module
@Injectable()
export class NoCacheHeadersInterceptor implements HttpInterceptor {
intercept(req: HttpRequest<any>, next: HttpHandler) {
const authReq = req.clone({
setHeaders: {
'Cache-Control': 'no-cache',
Pragma: 'no-cache'
}
});
return next.handle(authReq);
}
}
Then add this to your providers in your app.module
:
providers: [
... // other providers
{
provide: HTTP_INTERCEPTORS,
useClass: NoCacheHeadersInterceptor,
multi: true
},
... // other providers
]
This should prevent caching issues on live sites for client machines

The min-width
property does not work correctly in Internet Explorer, which is most likely the cause of your problems.
Read info and a brilliant script that fixes many IE CSS problems.
The simplest way is
local$ scp remote:{A/1,A/2,B/3,C/4}.txt ./
So {.. } list can include directories (A,B and C here are directories; "1.txt" and "2.txt" are file names in those directories).
Although it would copy all these four files into one local directory - not sure if that's what you wanted.
In the above case you will end up remote files A/1.txt, A/2.txt, B/3.txt and C/4.txt copied over to a single local directory, with file names ./1.txt, ./2.txt, ./3.txt and ./4.txt

Be sure to import the following lib into your model:
using System.ComponentModel.DataAnnotations;

Why do you set a status code in your request? and multiple declaration "Accept" with Accept:application/json,application/json,application/jsonrequest. just a statement is enough.
You can run a command in a running container using docker exec [OPTIONS] CONTAINER COMMAND [ARG...]

From there you can run your script.
Just finished up a js library for formatting numbers Numeral.js. It handles decimals, dollars, percentages and even time formatting.
Here's yet another answer offering commentary on how Muis, Abdullah Al-Ageel and Flip's answer are all mathematically the same thing except written differently.
Sure, we have José Manuel Ramos's analysis explaining how rounding errors affect each slightly differently, but that's implementation dependent and would change based on how each answer were applied to code.
It's in Muis's N
, Flip's k
, and Abdullah Al-Ageel's n
. Abdullah Al-Ageel doesn't quite explain what n
should be, but N
and k
differ in that N
is "the number of samples where you want to average over" while k
is the count of values sampled. (Although I have doubts to whether calling N
the number of samples is accurate.)
And here we come to the answer below. It's essentially the same old exponential weighted moving average as the others, so if you were looking for an alternative, stop right here.
Initially:
average = 0
counter = 0
For each value:
counter += 1
average = average + (value - average) / min(counter, FACTOR)
The difference is the min(counter, FACTOR)
part. This is the same as saying min(Flip's k, Muis's N)
.
FACTOR
is a constant that affects how quickly the average "catches up" to the latest trend. Smaller the number the faster. (At 1
it's no longer an average and just becomes the latest value.)
This answer requires the running counter counter
. If problematic, the min(counter, FACTOR)
can be replaced with just FACTOR
, turning it into Muis's answer. The problem with doing this is the moving average is affected by whatever average
is initiallized to. If it was initialized to 0
, that zero can take a long time to work its way out of the average.

In addition to the good advice already given, I would add this:
It is probably best to avoid using require()
unless you actually will be using the value it returns e.g in some error checking loop such as given by thierry.
In most other cases it is better to use library()
, because this will give an error message at package loading time if the package is not available. require()
will just fail without an error if the package is not there. This is the best time to find out if the package needs to be installed (or perhaps doesn't even exist because it it spelled wrong). Getting error feedback early and at the relevant time will avoid possible headaches with tracking down why later code fails when it attempts to use library routines
Oftentimes hooking refers to Win32 message hooking or the Linux/OSX equivalents, but more generically hooking is simply notifying another object/window/program/etc that you want to be notified when a specified action happens. For instance: Having all windows on the system notify you as they are about to close.
As a general rule, hooking is somewhat hazardous since doing it without understanding how it affects the system can lead to instability or at the very leas unexpected behaviour. It can also be VERY useful in certain circumstances, thought. For instance: FRAPS uses it to determine which windows it should show it's FPS counter on.
In postgres 12 I needed to use this command:
UPDATE DATABASECHANGELOGLOCK SET LOCKED=false, LOCKGRANTED=null, LOCKEDBY=null where ID=1;
Hovering over the icon "read only" in mysql workbench shows a tooltip that explains why it cannot be edited. In my case it said, only tables with primary keys or unique non-nullable columns can be edited.
You may use this package renderer, I have written to solve this kind of problem, it's a wrapper to serve JSON, JSONP, XML, HTML etc.
Slight modification to this @CodeMaker 's answer, for anyone like me who is trying to modify a MongoDB service to use authentication.
When I looked at the "Path to executable" in "Services" the executed line already contained speech marks. So I had to make minor modification to his example.
To be specific.
For me the path was (note the speech marks)
"C:\Program Files\MongoDB\Server\4.2\bin\mongod.exe" --config "C:\Program Files\MongoDB\Server\4.2\bin\mongod.cfg" --service
In a command line type
sc config MongoDB binPath= "<Modified string with \" to replace ">"
In my case this was
sc config MongoDB binPath= "\"C:\Program Files\MongoDB\Server\4.2\bin\mongod.exe\" --config \"C:\Program Files\MongoDB\Server\4.2\bin\mongod.cfg\" --service -- auth"

Just install cache eraser plugin, it is compatible with nb6.9, 7.0,7.1,7.2 and 7.3: To configure the plugin you have to provide the cache dir which is in netbean's about screen. Then with Tools->erase cache, you clear the netbeans cache. That is all, good luck.

Basically run it with:
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=1044
The application, at launch, will wait until you connect from another source.
Some programs can't process output stream very well, using pipe to Out-Null
may not block it.
And Start-Process
needs the -ArgumentList
switch to pass arguments, not so convenient.
There is also another approach.

I wrote a full replacement for sys.stderr
and just duplicated the code renaming stderr
to stdout
to make it also available to replace sys.stdout
.
To do this I create the same object type as the current stderr
and stdout
, and forward all methods to the original system stderr
and stdout
:

To use this you can just call StdErrReplament::lock(logger)
and StdOutReplament::lock(logger)
passing the logger you want to use to send the output text. For example:
import os
import sys
import logging
current_folder = os.path.dirname( os.path.realpath( __file__ ) )
log_file_path = os.path.join( current_folder, "my_log_file.txt" )
file_handler = logging.FileHandler( log_file_path, 'a' )
file_handler.formatter = logging.Formatter( "%(asctime)s %(name)s %(levelname)s - %(message)s", "%Y-%m-%d %H:%M:%S" )
log = logging.getLogger( __name__ )
log.setLevel( "DEBUG" )
log.addHandler( file_handler )
log.file_handler = file_handler
log.clean_formatter = logging.Formatter( "", "" )
StdOutReplament.lock( log )
StdErrReplament.lock( log )
log.debug( "I am doing usual logging debug..." )
sys.stderr.write( "Tests 1...\n" )
sys.stdout.write( "Tests 2...\n" )
Running this code, you will see on the screen:
And on the file contents:

While it would still saving this to the file my_log_file.txt
:
When disabling this with StdErrReplament:unlock()
, it will only restore the standard behavior of the stderr
stream, as the attached logger cannot be never detached because someone else can have a reference to its older version. This is why it is a global singleton which can never dies. Therefore, in case of reloading this module with imp
or something else, it will never recapture the current sys.stderr
as it was already injected on it and have it saved internally.
@Synxmax's answer is correct when using a Service
and the MediaPlayer
class, however you also need to declare the Service
in the Manifest for this to work, like so:
<service
android:enabled="true"
android:name="com.package.name.BackgroundSoundService" />

Version 7 of Angular has been released Official Angular blog link. Visit official angular update guide https://update.angular.io for detailed information. These steps will work for basic angular 6 apps using Angular Material.
ng update @angular/cli
ng update @angular/core
ng update @angular/material
Version 6 of Angular has been released Official Angular blog link. I have mentioned general upgrade steps below, but before and after the update you need to make changes in your code to make it workable in v6, for that detailed information visit official website https://update.angular.io .
Upgrade Steps (largely taken from the official Angular Update Guide for a basic Angular app using Angular Material):
Make sure NodeJS version is 8.9+ if not update it.
Update Angular cli globally and locally, and migrate the old configuration .angular-cli.json to the new angular.json format by running the following:
npm install -g @angular/cli
npm install @angular/cli
ng update @angular/cli
Update all of your Angular framework packages to v6,and the correct version of RxJS and TypeScript by running the following:
ng update @angular/core
Update Angular Material to the latest version by running the following:
ng update @angular/material
RxJS v6 has major changes from v5, v6 brings backwards compatibility package rxjs-compat that will keep your applications working, but you should refactor TypeScript code so that it doesn't depend on rxjs-compat. To refactor TypeScript code run following:
npm install -g rxjs-tslint
rxjs-5-to-6-migrate -p src/tsconfig.app.json
Note: Once all of your dependencies have updated to RxJS 6, remove rxjs- compat as it increases bundle size. please see this RxJS Upgrade Guide for more info.
npm uninstall rxjs-compat
Done run ng serve
to check it.
If you get errors in build refer https://update.angular.io for detailed info.
Upgrade rxjs to 6.0.0-beta.0, please see this RxJS Upgrade Guide for more info. RxJS v6 has breaking change hence first make your code compatible to latest RxJS version.
Update NodeJS version to 8.9+ (this is required by angular cli 6 version)
Update Angular cli global package to next version.
npm uninstall -g @angular/cli
npm cache verify
if npm version is < 5 then use npm cache clean
npm install -g @angular/cli@next
Change angular packages versions in package.json file to ^6.0.0-rc.5

The Angular CLI configuration format has been changed from angular cli 6.0.0-rc.2 version, and your existing configuration can be updated automatically by running the following command. It will remove old config file .angular-cli.json and will write new angular.json file.
ng update @angular/cli --migrate-only --from=1.7.4
Note :- If you get following error "The Angular Compiler requires TypeScript >=2.7.2 and <2.8.0 but 2.8.3 was found instead". run following command :
npm install [email protected]
Use &
SCSS
.container {
background:red;
color:white;
&.hello {
padding-left:50px;
}
}

The user-agent
should be specified as a field in the header.
Here is a list of HTTP header fields, and you'd probably be interested in request-specific fields, which includes User-Agent
.
The simplest way to do what you want is to create a dictionary and specify your headers directly, like so:
import requests
url = 'SOME URL'
headers = {
'User-Agent': 'My User Agent 1.0',
'From': '[email protected]' # This is another valid field
}
response = requests.get(url, headers=headers)
Older versions of requests
clobbered default headers, so you'd want to do the following to preserve default headers and then add your own to them.
import requests
url = 'SOME URL'
# Get a copy of the default headers that requests would use
headers = requests.utils.default_headers()
# Update the headers with your custom ones
# You don't have to worry about case-sensitivity with
# the dictionary keys, because default_headers uses a custom
# CaseInsensitiveDict implementation within requests' source code.
headers.update(
{
'User-Agent': 'My User Agent 1.0',
}
)
response = requests.get(url, headers=headers)
Use git rebase --abort
. From the official Linux kernel documentation for git rebase
:
git rebase --continue | --skip | --abort | --edit-todo
Just answering the second part of your question about getting the name of the sheet where a table is:
Dim name as String
name = Range("Table1").Worksheet.Name
Edit:
To make things more clear: someone suggested that to use Range on a Sheet object. In this case, you need not; the Range where the table lives can be obtained using the table's name; this name is available throughout the book. So, calling Range alone works well.
Strings are passed as reference types in .NET.
Reference types place a pointer on the stack, to the actual instance that resides on the managed heap. This is different to Value types, who hold their entire instance on the stack.
When a value type is passed as a parameter, the runtime creates a copy of the value on the stack and passes that value into a method. This is why integers must be passed with a 'ref' keyword to return an updated value.
When a reference type is passed, the runtime creates a copy of the pointer on the stack. That copied pointer still points to the original instance of the reference type.
The string type has an overloaded = operator which creates a copy of itself, instead of a copy of the pointer - making it behave more like a value type. However, if only the pointer was copied, a second string operation could accidently overwrite the value of a private member of another class causing some pretty nasty results.
As other posts have mentioned, the StringBuilder class allows for the creation of strings without the GC overhead.
I thought I had misunderstood but I was right. In this scenario, it will be ActiveWorkbook.Path
But the main issue was not here. The problem was with these 2 lines of code
strFile = Dir(strPath & "*.csv")
Which should have written as
strFile = Dir(strPath & "\*.csv")
and
With .QueryTables.Add(Connection:="TEXT;" & strPath & strFile, _
Which should have written as
With .QueryTables.Add(Connection:="TEXT;" & strPath & "\" & strFile, _
You need to use the fitBounds()
method.
var markers = [];//some array
var bounds = new google.maps.LatLngBounds();
for (var i = 0; i < markers.length; i++) {
bounds.extend(markers[i]);
}
map.fitBounds(bounds);
Documentation from developers.google.com/maps/documentation/javascript:
fitBounds(bounds[, padding])
Parameters:
`bounds`: [`LatLngBounds`][1]|[`LatLngBoundsLiteral`][1] `padding` (optional): number|[`Padding`][1]
Return Value: None
Sets the viewport to contain the given bounds.
Note: When the map is set todisplay: none
, thefitBounds
function reads the map's size as0x0
, and therefore does not do anything. To change the viewport while the map is hidden, set the map tovisibility: hidden
, thereby ensuring the map div has an actual size.
Use the .readline()
method (Python 2 docs, Python 3 docs):
with open('myfile.txt') as f:
first_line = f.readline()
Some notes:
f.readline()
will contain a trailing newline. You may wish to use f.readline().strip()
instead to remove the newline.with
statement automatically closes the file again when the block ends.with
statement only works in Python 2.5 and up, and in Python 2.5 you need to use from __future__ import with_statement
It worked for me after adding the following dependency in pom,
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.3.0.Final</version>
</dependency>
If you use the relative version on http://www.foo.com/abc your browser will look at http://www.foo.com/abc/kitten.png for the image and would get 404 - Not found.
In Oracle, you could do this:
create table D (
ID numeric(1),
CODE varchar(2),
constraint PK_D primary key (ID, CODE)
);
I would simply look for a $_GET
variable and redirect the user if it's not correct.
<?php
$pass = $_GET['pass'];
if($pass != 'my-secret-password') {
header('Location: http://www.staggeringbeauty.com/');
}
?>
Now, if this page is located at say: http://example.com/secrets/files.php
You can now access it with: http://example.com/secrets/files.php?pass=my-secret-password
Keep in mind that this isn't the most efficient or secure way, but nonetheless it is a easy and fast way. (Also, I know my answer is outdated but someone else looking at this question may find it valuable)
You need to add overflow:auto
to your parent div for it to encompass the inner floated div:
<div style="margin:0 auto;width: 960px; min-height: 100px; background-color:orange;overflow:auto">
<div style="width:500px; height:200px; background-color:black; float:right">
</div>
</div>
Evaluating "1,2,3" results in (1, 2, 3)
, a tuple
. As you've discovered, tuples are immutable. Convert to a list before processing.
var logged_in = false;
logged_in = !logged_in;
A little example:
var logged_in = false;_x000D_
_x000D_
_x000D_
$("#enable").click(function() {_x000D_
logged_in = !logged_in;_x000D_
checkLogin();_x000D_
});_x000D_
_x000D_
function checkLogin(){_x000D_
if (logged_in)_x000D_
$("#id_test").removeClass("test").addClass("test_hidde");_x000D_
else_x000D_
$("#id_test").removeClass("test_hidde").addClass("test");_x000D_

It doesn't appear that iframes display and scroll properly. You can use an object tag to replace an iframe and the contents will be scrollable with 2 fingers. Here's a simple example:
<html>
<head>
<meta name="viewport" content="minimum-scale=1.0; maximum-scale=1.0; user-scalable=false; initial-scale=1.0;"/>
</head>
<body>
<div>HEADER - use 2 fingers to scroll contents:</div>
<div id="scrollee" style="height:75%;" >
<object id="object" height="90%" width="100%" type="text/html" data="http://en.wikipedia.org/"></object>
</div>
<div>FOOTER</div>
</body>
</html>
Simple solution:
<iframe onload="this.style.height=this.contentWindow.document.body.scrollHeight + 'px';" ...></iframe>
This works when the iframe and parent window are in the same domain. It does not work when the two are in different domains.
java.time.Period
Use the java.time.Period
class to count days.
Since Java 8 calculating the difference is more intuitive using LocalDate
, LocalDateTime
to represent the two dates
LocalDate now = LocalDate.now();
LocalDate inputDate = LocalDate.of(2018, 11, 28);
Period period = Period.between( inputDate, now);
int diff = period.getDays();
System.out.println("diff = " + diff);
Assuming you want the format "(123) 456-7890
":
function formatPhoneNumber(phoneNumberString) {
var cleaned = ('' + phoneNumberString).replace(/\D/g, '')
var match = cleaned.match(/^(\d{3})(\d{3})(\d{4})$/)
if (match) {
return '(' + match[1] + ') ' + match[2] + '-' + match[3]
}
return null
}
Here's a version that allows the optional +1
international code:
function formatPhoneNumber(phoneNumberString) {
var cleaned = ('' + phoneNumberString).replace(/\D/g, '')
var match = cleaned.match(/^(1|)?(\d{3})(\d{3})(\d{4})$/)
if (match) {
var intlCode = (match[1] ? '+1 ' : '')
return [intlCode, '(', match[2], ') ', match[3], '-', match[4]].join('')
}
return null
}
formatPhoneNumber('+12345678900') // => "+1 (234) 567-8900"
formatPhoneNumber('2345678900') // => "(234) 567-8900"
Try this:
<uses-permission android:name="android.permission.INTERNET"/>
And your activity names
must be like this with capital letters
:
<activity android:name=".Addfriend"/>
<activity android:name=".UpdateDetails"/>
<activity android:name=".Details"/>
<activity android:name=".Updateimage"/>
Maybe the "Output type" in properties->Application of the project must be a "Class Library" instead of console or windows application.
A Quote from : iPhone Developer Program (~8MB PDF)
A provisioning profile is a collection of digital entities that uniquely ties developers and devices to an authorized iPhone Development Team and enables a device to be used for testing. A Development Provisioning Profile must be installed on each device on which you wish to run your application code. Each Development Provisioning Profile will contain a set of iPhone Development Certificates, Unique Device Identifiers and an App ID. Devices specified within the provisioning profile can be used for testing only by those individuals whose iPhone Development Certificates are included in the profile. A single device can contain multiple provisioning profiles.
How about:
import re
s = "alpha.Customer[cus_Y4o9qMEZAugtnW] ..."
m = re.search(r"\[([A-Za-z0-9_]+)\]", s)
print m.group(1)
For me this prints:
cus_Y4o9qMEZAugtnW
Note that the call to re.search(...)
finds the first match to the regular expression, so it doesn't find the [card]
unless you repeat the search a second time.
Edit: The regular expression here is a python raw string literal, which basically means the backslashes are not treated as special characters and are passed through to the re.search()
method unchanged. The parts of the regular expression are:
\[
matches a literal [
character(
begins a new group[A-Za-z0-9_]
is a character set matching any letter (capital or lower case), digit or underscore+
matches the preceding element (the character set) one or more times.)
ends the group\]
matches a literal ]
characterEdit: As D K has pointed out, the regular expression could be simplified to:
m = re.search(r"\[(\w+)\]", s)
since the \w
is a special sequence which means the same thing as [a-zA-Z0-9_]
depending on the re.LOCALE
and re.UNICODE
settings.
The following simple way to create radio button in your iOS app follow two steps.
Step1- Put this code in your in viewDidLoad or any other desired method
[_mrRadio setSelected:YES];
[_mrRadio setTag:1];
[_msRadio setTag:1];
[_mrRadio setBackgroundImage:[UIImage imageNamed:@"radiodselect_white.png"] forState:UIControlStateNormal];
[_mrRadio setBackgroundImage:[UIImage imageNamed:@"radioselect_white.png"] forState:UIControlStateSelected];
[_mrRadio addTarget:self action:@selector(radioButtonSelected:) forControlEvents:UIControlEventTouchUpInside];
[_msRadio setBackgroundImage:[UIImage imageNamed:@"radiodselect_white.png"] forState:UIControlStateNormal];
[_msRadio setBackgroundImage:[UIImage imageNamed:@"radioselect_white.png"] forState:UIControlStateSelected];
[_msRadio addTarget:self action:@selector(radioButtonSelected:) forControlEvents:UIControlEventTouchUpInside];
Step2- Put following IBAction method in your class
-(void)radioButtonSelected:(id)sender
{
switch ([sender tag ]) {
case 1:
if ([_mrRadio isSelected]==YES) {
// [_mrRadio setSelected:NO];
// [_msRadio setSelected:YES];
genderType = @"1";
}
else
{
[_mrRadio setSelected:YES];
[_msRadio setSelected:NO];
genderType = @"1";
}
break;
case 2:
if ([_msRadio isSelected]==YES) {
// [_msRadio setSelected:NO];
// [_mrRadio setSelected:YES];
genderType = @"2";
}
else
{
[_msRadio setSelected:YES];
[_mrRadio setSelected:NO];
genderType = @"2";
}
break;
default:
break;
}
}
What @Darin said is what I would recommend as well. However I would add to it (and in response to one of the comments) that you can in fact also use this method for primitive types like bit, bool, even structures like Guid by simply making them nullable. Once you do this, the Required
attribute functions as expected.
public UpdateViewView
{
[Required]
public Guid? Id { get; set; }
[Required]
public string Name { get; set; }
[Required]
public int? Age { get; set; }
[Required]
public bool? IsApproved { get; set; }
//... some other properties
}

If all you want to do is read the same information more than once, and the input data is small enough to fit into memory, you can copy the data from your InputStream
to a ByteArrayOutputStream.
Then you can obtain the associated array of bytes and open as many "cloned" ByteArrayInputStreams as you like.
ByteArrayOutputStream baos = new ByteArrayOutputStream();
// Code simulating the copy
// You could alternatively use NIO
// And please, unlike me, do something about the Exceptions :D
byte[] buffer = new byte[1024];
int len;
while ((len = input.read(buffer)) > -1 ) {
baos.write(buffer, 0, len);
}
baos.flush();
// Open new InputStreams using recorded bytes
// Can be repeated as many times as you wish
InputStream is1 = new ByteArrayInputStream(baos.toByteArray());
InputStream is2 = new ByteArrayInputStream(baos.toByteArray());
But if you really need to keep the original stream open to receive new data, then you will need to track the external call to close()
. You will need to prevent close()
from being called somehow.
Since Java 9 the the middle bits can be replaced with InputStream.transferTo
:
ByteArrayOutputStream baos = new ByteArrayOutputStream();
input.transferTo(baos);
InputStream firstClone = new ByteArrayInputStream(baos.toByteArray());
InputStream secondClone = new ByteArrayInputStream(baos.toByteArray());
Although the answer set is complete, I need to add another missing one.
for i in *_h.png;
do name=`echo "$i" | cut -d'_' -f1`
echo "Executing of name $name"
mv "$i" "${name}_half.png"
done
I think is more robust to use regular expressions:
import re
for i, line in enumerate(content):
print line if not (re.match('\r?\n', line)) else pass
This would match in Windows/unix. In addition if you are not sure about lines containing only space char you could use '\s*\r?\n'
as expression
As the plural in getElementsByName()
implies, does it always return list of elements that have this name. So when you have an input element with that name:
<input type="text" name="Tue">
And it is the first one with that name, you have to use document.getElementsByName('Tue')[0]
to get the first element of the list of elements with this name.
Beside that are properties case sensitive and the correct spelling of the value property is .value
.
Laravel has introduced Named Routes in Laravel 4.2.
WHAT IS NAMED ROUTES?
Named Routes allows you to give names to your router path. Hence using the name we can call the routes in required file.
HOW TO CREATE NAMED ROUTES?
Named Routes created in two different way : as and name()
METHOD 1:
Route::get('about',array('as'=>'about-as',function()
{
return view('about');
}
));
METHOD 2:
Route::get('about',function()
{
return view('about');
})->name('about-as');
How we use in views?
<a href="{{ URL::route("about-as") }}">about-as</a>
Hence laravel 'middleware'=>'auth' has already predefined for redirect as login page if user has not yet logged in.Hence we should use as keyword
Route::get('login',array('as'=>'login',function(){
return view('login');
}));
I'm not aware of any particular convention for javascript files as they aren't really unique on the web versus css files or html files or any other type of file like that. There are some "safe" things you can do that make it less likely you will accidentally run into a cross platform issue:
various-scripts.js
, a hyphen is a safe and useful and commonly used separator.A possible solution might be to use the JSON dumps() method, so you can convert the dictionary to a string ---
import json
a={"a":10, "b":20}
b={"b":20, "a":10}
c = [json.dumps(a), json.dumps(b)]
set(c)
json.dumps(a) in c
Output -
set(['{"a": 10, "b": 20}'])
True
Its kind of relative path Instead of the below code
import { Something } from "../../../../../lib/src/[browser/server/universal]/...";
We can avoid the "../../../../../" its looking odd and not readable too.
So Typescript config file have answer for the same. Just specify the baseUrl, config will take care of your relative path.
way to config: tsconfig.json file add the below properties.
"baseUrl": "src",
"paths": {
"@app/*": [ "app/*" ],
"@env/*": [ "environments/*" ]
}
So Finally it will look like below
import { Something } from "@app/src/[browser/server/universal]/...";
Its looks simple,awesome and more readable..
System.Convert.ChangeType(jtoken.ToString(), targetType);
or
JsonConvert.DeserializeObject(jtoken.ToString(), targetType);
--EDIT--
Uzair, Here is a complete example just to show you they work
string json = @"{
""id"" : 77239923,
""username"" : ""UzEE"",
""email"" : ""[email protected]"",
""name"" : ""Uzair Sajid"",
""twitter_screen_name"" : ""UzEE"",
""join_date"" : ""2012-08-13T05:30:23Z05+00"",
""timezone"" : 5.5,
""access_token"" : {
""token"" : ""nkjanIUI8983nkSj)*#)(kjb@K"",
""scope"" : [ ""read"", ""write"", ""bake pies"" ],
""expires"" : 57723
},
""friends"" : [{
""id"" : 2347484,
""name"" : ""Bruce Wayne""
},
{
""id"" : 996236,
""name"" : ""Clark Kent""
}]
}";
var obj = (JObject)JsonConvert.DeserializeObject(json);
Type type = typeof(int);
var i1 = System.Convert.ChangeType(obj["id"].ToString(), type);
var i2 = JsonConvert.DeserializeObject(obj["id"].ToString(), type);
This will work:
$stringToSplit = 'This is my String!' ."\n\r". 'Second Line';
$split = explode (
' ', implode (
' ', explode (
"\n\r", $stringToSplit
)
)
);
As you can see, it first glues the by \n\r exploded parts together with a space, to then cut it apart again, this time taking the spaces with him.
It's rather difficult to give a practical answer because the difference is about the language definition itself. It's possible to build an interpreter for every compiled language, but it's not possible to build an compiler for every interpreted language. It's very much about the formal definition of a language. So that theoretical informatics stuff noboby likes at university.
The reason why this happened to me was that a remote server was allowing only certain IP addressed but not its own, and I was trying to render the images from the server's URLs... so everything would simply halt, displaying the timeout error that you had...
Make sure that either the server is allowing its own IP, or that you are rendering things from some remote URL that actually exists.
The Request Payload - or to be more precise: payload body of a HTTP Request
- is the data normally send by a POST or PUT Request.
It's the part after the headers and the CRLF
of a HTTP Request.
A request with Content-Type: application/json
may look like this:
POST /some-path HTTP/1.1
Content-Type: application/json
{ "foo" : "bar", "name" : "John" }
If you submit this per AJAX the browser simply shows you what it is submitting as payload body. That’s all it can do because it has no idea where the data is coming from.
If you submit a HTML-Form with method="POST"
and Content-Type: application/x-www-form-urlencoded
or Content-Type: multipart/form-data
your request may look like this:
POST /some-path HTTP/1.1
Content-Type: application/x-www-form-urlencoded
foo=bar&name=John
In this case the form-data is the request payload. Here the Browser knows more: it knows that bar is the value of the input-field foo of the submitted form. And that’s what it is showing to you.
So, they differ in the Content-Type
but not in the way data is submitted. In both cases the data is in the message-body. And Chrome distinguishes how the data is presented to you in the Developer Tools.
As an addition to npm version
you can use the --no-git-tag-version
flag if you want a version bump but no tag or a new commit:
npm --no-git-tag-version version patch
Just an additional hint for avoiding too much JavaScript here: if you add a label and style it like the "browse button" you want to have, you could place it over the real browse button provided by the browser or hide the button somehow differently. By clicking the label the browser behavior is to open the dialog to browse for the file (don't forget to add the "for" attribute on the label with value of the id of the file input field to make this happen). That way you can customize the button in almost any way you want.
In some cases, it might be necessary to add a second input field or text element to display the value of the file input and hide the input completely as described in other answers. Still the label would avoid to simulate the click on the text input button by JavaScript.
BTW a similar hack can be used for customizing checkboxes or radiobuttons. by adding a label for them, clicking the label causes to select the checkbox/radiobutton. The native checkbox/radiobutton then can be hidden somewere and be replaced by a custom element.
When you say:
c is not None
You are actually checking if c and None reference the same object. That is what the "is" operator does. In python None is a special null value conventionally meaning you don't have a value available. Sorta like null in c or java. Since python internally only assigns one None value using the "is" operator to check if something is None (think null) works, and it has become the popular style. However this does not have to do with the truth value of the set c, it is checking that c actually is a set rather than a null value.
If you want to check if a set is empty in a conditional statement, it is cast as a boolean in context so you can just say:
c = set()
if c:
print "it has stuff in it"
else:
print "it is empty"
But if you want it converted to a boolean to be stored away you can simply say:
c = set()
c_has_stuff_in_it = bool(c)
What you've written actually almost works (it would work if all the variables were numbers), but it's not an idiomatic way at all.
(…)
parentheses indicate a subshell. What's inside them isn't an expression like in many other languages. It's a list of commands (just like outside parentheses). These commands are executed in a separate subprocess, so any redirection, assignment, etc. performed inside the parentheses has no effect outside the parentheses.
$(…)
is a command substitution: there is a command inside the parentheses, and the output from the command is used as part of the command line (after extra expansions unless the substitution is between double quotes, but that's another story).{ … }
braces are like parentheses in that they group commands, but they only influence parsing, not grouping. The program x=2; { x=4; }; echo $x
prints 4, whereas x=2; (x=4); echo $x
prints 2. (Also braces require spaces around them and a semicolon before closing, whereas parentheses don't. That's just a syntax quirk.)
${VAR}
is a parameter expansion, expanding to the value of a variable, with possible extra transformations.((…))
double parentheses surround an arithmetic instruction, that is, a computation on integers, with a syntax resembling other programming languages. This syntax is mostly used for assignments and in conditionals.
$((…))
, which expand to the integer value of the expression.[[ … ]]
double brackets surround conditional expressions. Conditional expressions are mostly built on operators such as -n $variable
to test if a variable is empty and -e $file
to test if a file exists. There are also string equality operators: "$string1" == "$string2"
(beware that the right-hand side is a pattern, e.g. [[ $foo == a* ]]
tests if $foo
starts with a
while [[ $foo == "a*" ]]
tests if $foo
is exactly a*
), and the familiar !
, &&
and ||
operators for negation, conjunction and disjunction as well as parentheses for grouping. Note that you need a space around each operator (e.g. [[ "$x" == "$y" ]]
, not [[ "$x"=="$y" ]]
;
both inside and outside the brackets (e.g. [[ -n $foo ]]
, not [[-n $foo]]
[ … ]
single brackets are an alternate form of conditional expressions with more quirks (but older and more portable). Don't write any for now; start worrying about them when you find scripts that contain them.This is the idiomatic way to write your test in bash:
if [[ $varA == 1 && ($varB == "t1" || $varC == "t2") ]]; then
If you need portability to other shells, this would be the way (note the additional quoting and the separate sets of brackets around each individual test, and the use of the traditional =
operator rather than the ksh/bash/zsh ==
variant):
if [ "$varA" = 1 ] && { [ "$varB" = "t1" ] || [ "$varC" = "t2" ]; }; then
Or you can style it with pixels.
.big-checkbox {width: 30px; height: 30px;}

Without any example data, it really is difficult to know exactly what you are wanting. For instance, I can't at all divine what your object set
(or is it sets
) looks like.
That said, does the following help at all?
set1 <- data.frame(x = 4:6, y = 6:4, z = c(1, 3, 5))
plot(1:10, type="n")
XX <- "set1"
with(eval(as.symbol(XX)), symbols(x, y, circles = z, add=TRUE))
EDIT:
Now that I see your real task, here is a one-liner that'll do everything you want without requiring any for()
loops:
with(dat, symbols(sq, cu, circles = num,
bg = c("red", "blue")[(num>5) + 1]))
The one bit of code that may feel odd is the bit specifying the background color. Try out these two lines to see how it works:
c(TRUE, FALSE) + 1
# [1] 2 1
c("red", "blue")[c(F, F, T, T) + 1]
# [1] "red" "red" "blue" "blue"
WHERE column_name LIKE '%save 50[%] off!%'
Just my 2 cents as stated in the answer above : The copy() method shouldn't be used as-is for copying files without a slight adjustment:
function copy(callback) {
var readStream = fs.createReadStream(oldPath);
var writeStream = fs.createWriteStream(newPath);
readStream.on('error', callback);
writeStream.on('error', callback);
// Do not callback() upon "close" event on the readStream
// readStream.on('close', function () {
// Do instead upon "close" on the writeStream
writeStream.on('close', function () {
callback();
});
readStream.pipe(writeStream);
}
The copy function wrapped in a Promise:
function copy(oldPath, newPath) {
return new Promise((resolve, reject) => {
const readStream = fs.createReadStream(oldPath);
const writeStream = fs.createWriteStream(newPath);
readStream.on('error', err => reject(err));
writeStream.on('error', err => reject(err));
writeStream.on('close', function() {
resolve();
});
readStream.pipe(writeStream);
})
However, keep in mind that the filesystem might crash if the target folder doesn't exist.
With the new Angular router, you can add a [routerLinkActive]="['your-class-name']"
attribute to all your links:
<a [routerLink]="['/home']" [routerLinkActive]="['is-active']">Home</a>
Or the simplified non-array format if only one class is needed:
<a [routerLink]="['/home']" [routerLinkActive]="'is-active'">Home</a>
Or an even simpler format if only one class is needed:
<a [routerLink]="['/home']" routerLinkActive="is-active">Home</a>
See the poorly documented routerLinkActive
directive for more info. (I mostly figured this out via trial-and-error.)
UPDATE: Better documentation for the routerLinkActive
directive can now be found here. (Thanks to @Victor Hugo Arango A. in the comments below.)
This does almost everything you want:
f = open('data.txt', 'rb')
while True:
char = f.read(1)
if not char: break
print "{:02x}".format(ord(char)),
With data.txt created like this:
f = open('data.txt', 'wb')
f.write("ab\r\ncd")
f.close()
I get the following output:
61 62 0d 0a 63 64
tl;dr -- 1. You are using poor variable names. 2. You are slicing your hex strings incorrectly. 3. Your code is never going to replace any newlines. You may just want to forget about that feature. You do not quite yet understand the difference between a character, its integer code, and the hex string that represents the integer. They are all different: two are strings and one is an integer, and none of them are equal to each other. 4. For some files, you shouldn't remove newlines.
===
1. Your variable names are horrendous.
That's fine if you never want to ask anybody questions. But since every one needs to ask questions, you need to use descriptive variable names that anyone can understand. Your variable names are only slightly better than these:
fname = 'data.txt'
f = open(fname, 'rb')
xxxyxx = f.read()
xxyxxx = len(xxxyxx)
print "Length of file is", xxyxxx, "bytes. "
yxxxxx = 0
while yxxxxx < xxyxxx:
xyxxxx = hex(ord(xxxyxx[yxxxxx]))
xyxxxx = xyxxxx[-2:]
yxxxxx = yxxxxx + 1
xxxxxy = chr(13) + chr(10)
xxxxyx = str(xxxxxy)
xyxxxxx = str(xyxxxx)
xyxxxxx.replace(xxxxyx, ' ')
print xyxxxxx
That program runs fine, but it is impossible to understand.
2. The hex() function produces strings of different lengths.
For instance,
print hex(61)
print hex(15)
--output:--
0x3d
0xf
And taking the slice [-2:] for each of those strings gives you:
3d
xf
See how you got the 'x' in the second one? The slice:
[-2:]
says to go to the end of the string and back up two characters, then grab the rest of the string. Instead of doing that, take the slice starting 3 characters in from the beginning:
[2:]
3. Your code will never replace any newlines.
Suppose your file has these two consecutive characters:
"\r\n"
Now you read in the first character, "\r", and convert it to an integer, ord("\r"), giving you the integer 13. Now you convert that to a string, hex(13), which gives you the string "0xd"
, and you slice off the first two characters giving you:
"d"
Next, this line in your code:
bndtx.replace(entx, ' ')
tries to find every occurrence of the string "\r\n"
in the string "d"
and replace it. There is never going to be any replacement because the replacement string is two characters long and the string "d"
is one character long.
The replacement won't work for "\r\n"
and "0d"
either. But at least now there is a possibility it could work because both strings have two characters. Let's reduce both strings to a common denominator: ascii codes. The ascii code for "\r" is 13, and the ascii code for "\n" is 10. Now what about the string "0d"
? The ascii code for the character "0"
is 48, and the ascii code for the character "d" is 100. Those strings do not have a single character in common. Even this doesn't work:
x = '0d' + '0a'
x.replace("\r\n", " ")
print x
--output:--
'0d0a'
Nor will this:
x = 'd' + 'a'
x.replace("\r\n", " ")
print x
--output:--
da
The bottom line is: converting a character to an integer then to a hex string does not end up giving you the original character--they are just different strings. So if you do this:
char = "a"
code = ord(char)
hex_str = hex(code)
print char.replace(hex_str, " ")
...you can't expect "a" to be replaced by a space. If you examine the output here:
char = "a"
print repr(char)
code = ord(char)
print repr(code)
hex_str = hex(code)
print repr(hex_str)
print repr(
char.replace(hex_str, " ")
)
--output:--
'a'
97
'0x61'
'a'
You can see that 'a' is a string with one character in it, and '0x61'
is a string with 4 characters in it: '0'
, 'x'
, '6'
, and '1'
, and you can never find a four character string inside a one character string.
4) Removing newlines can corrupt the data.
For some files, you do not want to replace newlines. For instance, if you were reading in a .jpg file, which is a file that contains a bunch of integers representing colors in an image, and some colors in the image happened to be represented by the number 13 followed by the number 10, your code would eliminate those colors from the output.
However, if you are writing a program to read only text files, then replacing newlines is fine. But then, different operating systems use different newlines. You are trying to replace Windows newlines(\r\n), which means your program won't work on files created by a Mac or Linux computer, which use \n for newlines. There are easy ways to solve that, but maybe you don't want to worry about that just yet.
I hope all that's not too confusing.
>>>var=7
>>>array = [1,2,3,4,5,6]
>>>array.insert(0,var)
>>>array
[7, 1, 2, 3, 4, 5, 6]
How it works:
array.insert(index, value)
Insert an item at a given position. The first argument is the index of the element before which to insert, so array.insert(0, x)
inserts at the front of the list, and array.insert(len(array), x)
is equivalent to array.append(x)
.Negative values are treated as being relative to the end of the array.
One of Androids powerful feature is the AsyncTask class.
To work with it, you have to first extend it and override doInBackground
(...).
doInBackground
automatically executes on a worker thread, and you can add some
listeners on the UI Thread to get notified about status update, those functions are
called: onPreExecute()
, onPostExecute()
and onProgressUpdate()
You can find a example here.
Refer to below post for other alternatives:
Swift answer:
myButton.addTarget(self, action: "click:", for: .touchUpInside)
func click(sender: UIButton) {
print("click")
}
Documentation: https://developer.apple.com/documentation/uikit/uicontrol/1618259-addtarget
You could use :focus
which will remain the style as long as the user doesn't click elsewhere.
button:active {
border: 2px solid green;
}
button:focus {
border: 2px solid red;
}
If your find
handles this syntax, you can use it:
find -maxdepth 1 -name "file.txt" -size -90k
This will output file.txt
to stdout if and only if the size of file.txt
is less than 90k. To execute a script script
if file.txt
has a size less than 90k:
find -maxdepth 1 -name "file.txt" -size -90k -exec script \;

This program counts the number of all substrings even if they are overlapped without the use of regex. But this is a naive implementation and for better results in worst case it is advised to go through either Suffix Tree, KMP and other string matching data structures and algorithms.
Or, similar to erikkallen's idea, make the background of the A tag black, and make the image semitransparent on mouseover. That way you won't have to create additional divs.
Source for the CSS-based solution:

It can be done recursively via the function:
CREATE FUNCTION dbo.RemSpaceFromStr(@str VARCHAR(MAX)) RETURNS VARCHAR(MAX) AS
BEGIN
RETURN (CASE WHEN CHARINDEX(' ', @str) > 0 THEN
dbo.RemSpaceFromStr(REPLACE(@str, ' ', ' ')) ELSE @str END);
END
then, for example:
SELECT dbo.RemSpaceFromStr('some string with many spaces') AS NewStr
returns:
NewStr
some string with many spaces
Or the solution based on method described by @agdk26 or @Neil Knight (but safer)
both examples return output above:
SELECT REPLACE(REPLACE(REPLACE('some string with many spaces'
, ' ', ' ' + CHAR(7)), CHAR(7) + ' ', ''), ' ' + CHAR(7), ' ') AS NewStr
--but it remove CHAR(7) (Bell) from string if exists...
or
SELECT REPLACE(REPLACE(REPLACE('some string with many spaces'
, ' ', ' ' + CHAR(7) + CHAR(7)), CHAR(7) + CHAR(7) + ' ', ''), ' ' + CHAR(7) + CHAR(7), ' ') AS NewStr
--but it remove CHAR(7) + CHAR(7) from string
Caution:
Char/string used to replace spaces shouldn't exist on begin or end of string and stand alone.
Here is very good answer of your question
see the example mentioned on above MSDN page :-
This should do
import pylab as plot
params = {'legend.fontsize': 20,
'legend.handlelength': 2}
plot.rcParams.update(params)
Then do the plot afterwards.
There are a ton of other rcParams, they can also be set in the matplotlibrc file.
Also presumably you can change it passing a matplotlib.font_manager.FontProperties
instance but this I don't know how to do. --> see Yann's answer.

How to debug SQL queries when you stuck
Print you query and run it directly in mysql or phpMyAdmin
$date = "2012-08-06";
$query= "INSERT INTO data_table (title, date_of_event)
VALUES('". $_POST['post_title'] ."',
'". $date ."')";
echo $query;
mysql_query($query) or die(mysql_error());
that way you can make sure that the problem is not in your PHP-script, but in your SQL-query

This will return the split DataFrames if the condition is met, otherwise return the original and None
(which you would then need to handle separately). Note that this assumes the splitting only has to happen one time per df
and that the second part of the split (if it is longer than 10 rows (meaning that the original was longer than 20 rows)) is OK.
df_new1, df_new2 = df[:10, :], df[10:, :] if len(df) > 10 else df, None
Note you can also use df.head(10)
and df.tail(len(df) - 10)
to get the front and back according to your needs. You can also use various indexing approaches: you can just provide the first dimensions index if you want, such as df[:10]
instead of df[:10, :]
(though I like to code explicitly about the dimensions you are taking). You can can also use df.iloc
and df.ix
to index in similar ways.
Be careful about using df.loc
however, since it is label-based and the input will never be interpreted as an integer position. .loc
would only work "accidentally" in the case when you happen to have index labels that are integers starting at 0 with no gaps.
But you should also consider the various options that pandas provides for dumping the contents of the DataFrame into HTML and possibly also LaTeX to make better designed tables for the presentation (instead of just copying and pasting). Simply Googling how to convert the DataFrame to these formats turns up lots of tutorials and advice for exactly this application.
You can use Bundle to do the same in Android
Create the intent:
Intent i = new Intent(this, ActivityTwo.class);
AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autocomplete);
String getrec=textView.getText().toString();
//Create the bundle
Bundle bundle = new Bundle();
//Add your data to bundle
bundle.putString(“stuff”, getrec);
//Add the bundle to the intent
i.putExtras(bundle);
//Fire that second activity
startActivity(i);
Now in your second activity retrieve your data from the bundle:
//Get the bundle
Bundle bundle = getIntent().getExtras();
//Extract the data…
String stuff = bundle.getString(“stuff”);
If you have simple flavors (free/pro, demo/full etc.) then add to build.gradle file:
android {
...
flavorDimensions "version"
productFlavors {
free{
dimension "version"
...
}
pro{
dimension "version"
...
}
}
By dimensions you can create "flavors in flavors". Read more.
You can do the following (which I find trivial, but its actually correct). For anyone trying to find how to initialize a two-dimensional array in TypeScript (like myself).
Let's assume that you want to initialize a two-dimensional array, of any type. You can do the following
const myArray: any[][] = [];
And later, when you want to populate it, you can do the following:
myArray.push([<your value goes here>]);
A short example of the above can be the following:
const myArray: string[][] = [];
myArray.push(["value1", "value2"]);
The simplest in my opinion is just this:
it = iter([1,2,3,4,5,6])
for x, y in zip(it, it):
print x, y
Out: 1 2
3 4
5 6
No extra imports or anything. And very elegant, in my opinion.
Each elapsed event will fire in the same thread unless a previous Elapsed is still running.
So it handles the collision for you
try putting this in a console
static void Main(string[] args)
{
Debug.WriteLine(Thread.CurrentThread.ManagedThreadId);
var timer = new Timer(1000);
timer.Elapsed += timer_Elapsed;
timer.Start();
Console.ReadLine();
}
static void timer_Elapsed(object sender, ElapsedEventArgs e)
{
Thread.Sleep(2000);
Debug.WriteLine(Thread.CurrentThread.ManagedThreadId);
}
you will get something like this
10
6
12
6
12
where 10 is the calling thread and 6 and 12 are firing from the bg elapsed event. If you remove the Thread.Sleep(2000); you will get something like this
10
6
6
6
6
Since there are no collisions.
But this still leaves u with a problem. if u are firing the event every 5 seconds and it takes 10 seconds to edit u need some locking to skip some edits.
The C++ 11 way is to use std::stod and std::to_string. Both work in Visual Studio 11.
This is similar to aSeptik's answer, but what about this approach? Wrap the CSS code which you want to disable using JavaScript in <noscript>
tags. That way if javaScript is off, the CSS :hover
will be used, otherwise the JavaScript effect will be used.
Example:
<noscript>
<style type="text/css">
ul#mainFilter a:hover {
/* some CSS attributes here */
}
</style>
</noscript>
<script type="text/javascript">
$("ul#mainFilter a").hover(
function(o){ /* ...do your stuff... */ },
function(o){ /* ...do your stuff... */ });
</script>

No, because there's no precompiler. However, in your case you could achieve the same thing as follows:
class MyClass
{
private static final int PROTEINS = 0;
...
MyArray[] foo = new MyArray[PROTEINS];
}
The compiler will notice that PROTEINS
can never, ever change and so will inline it, which is more or less what you want.
Note that the access modifier on the constant is unimportant here, so it could be public
or protected
instead of private, if you wanted to reuse the same constant across multiple classes.
You can try using groovy. It runs on the JVM and it comes with great support for running external processes and extracting the output:
http://groovy.codehaus.org/Executing+External+Processes+From+Groovy
You can see in this code taken from the same link how groovy makes it easy to get the status of the process:
println "return code: ${ proc.exitValue()}"
println "stderr: ${proc.err.text}"
println "stdout: ${proc.in.text}" // *out* from the external program is *in* for groovy
If you need to do a file upload, you'll need to use MediaType.MULTIPART_FORM_DATA_TYPE. Looks like MultivaluedMap cannot be used with that so here's a solution with FormDataMultiPart.
InputStream stream = getClass().getClassLoader().getResourceAsStream(fileNameToUpload);
FormDataMultiPart part = new FormDataMultiPart();
part.field("String_key", "String_value");
part.field("fileToUpload", stream, MediaType.TEXT_PLAIN_TYPE);
String response = WebResource.type(MediaType.MULTIPART_FORM_DATA_TYPE).post(String.class, part);
I did it using: if(x.getClass() == MyClass.class){...}
guppy3 is quite simple to use. At some point in your code, you have to write the following:

You can also find out from where objects are referenced and get statistics about that, but somehow the docs on that are a bit sparse.
There is a graphical browser as well, written in Tk.
For Python 2.x, use Heapy.
As simple as that.
var str = '{"id":1,"name":"Test1"},{"id":2,"name":"Test2"}';
dataObj = JSON.parse(str);
I couldn't get the other answers to work within the evaluate console in Intellij so...
groovy.json.JsonOutput.toJson(myObject)
This works quite well, but unfortunately
groovy.json.JsonOutput.prettyString(myObject)
didn't work for me.
To get it pretty printed I had to do this...
groovy.json.JsonOutput.prettyPrint(groovy.json.JsonOutput.toJson(myObject))
Note that Mongo essentially stores JSON. If your app is dealing with a lot of JS Objects (with nesting) and you want to persist these objects then there is a very strong argument for using Mongo. It makes your DAL and MVC layers ultra thin, because they are not un-packaging all the JS object properties and trying to force-fit them into a structure (schema) that they don't naturally fit into.
We have a system that has several complex JS Objects at its heart, and we love Mongo because we can persist everything really, really easily. Our objects are also rather amorphous and unstructured, and Mongo soaks up that complication without blinking. We have a custom reporting layer that deciphers the amorphous data for human consumption, and that wasn't that difficult to develop.
This method will preserve the original array, and check for bounding errors.
const move = (from, to, arr) => {
to = Math.max(to,0)
from > to
? [].concat(
arr.slice(0,to),
arr[from],
arr.filter((x,i) => i != from).slice(to))
: to > from
? [].concat(
arr.slice(0, from),
arr.slice(from + 1, to + 1),
arr[from],
arr.slice(to + 1))
: arr}
You can run composer show -i
(short for --installed
).
In the latest version just use composer show
.
The -i
options has been deprecated.
You can also use the global
instalation of composer: composer global show
As a side note processes that uses virtual accounts (NT Service\MyService and IIS AppPool\MyAppPool) are still running under the "NETWORK SERVICE" account as this post suggests http://www.adopenstatic.com/cs/blogs/ken/archive/2008/01/29/15759.aspx. The only difference is that these processes are members of the "NT Service\MyService" or "IIS AppPool\MyAppPool" groups (as these are actually groups and not users). This is also the reason why the processes authenticate at the network as the machine the same way NETWORK SERVICE account does.
The way to secure access is not to depend upon this accounts not having NETWORK SERVICE privileges but to grant more permissions specifically to "NT Service\MyService" or "IIS AppPool\MyAppPool" and to remove permissions for "Users" if necessary.
If anyone has more accurate or contradictional information please post.
