Just for others getting this error and looking for info on it, it is also thrown if you happen to pass a binding parameter and then never use it. I couldn't really find that stated clearly anywhere but had to prove it through trial and error.
Often the order of the processing does not matter. GNU Parallel is made for this situation:
grep xyz abc.txt | parallel echo do stuff to {}
If you processing is more like:
grep xyz abc.txt | myprogram_reading_from_stdin
and myprogram
is slow then you can run:
grep xyz abc.txt | parallel --pipe myprogram_reading_from_stdin
The only easy way to do this is to use snprintf
to print to a buffer that's long enough to hold the entire, exact value, then truncate it as a string. Something like:
char buf[2*(DBL_MANT_DIG + DBL_MAX_EXP)];
snprintf(buf, sizeof buf, "%.*f", (int)sizeof buf, x);
char *p = strchr(buf, '.'); // beware locale-specific radix char, though!
p[2+1] = 0;
puts(buf);
From Java 8 onward you can try the following:
import java.time.*;
import java.time.temporal.ChronoUnit;
Instant start_time = Instant.now();
// Your code
Instant stop_time = Instant.now();
System.out.println(Duration.between(start_time, stop_time).toMillis());
//or
System.out.println(ChronoUnit.MILLIS.between(start_time, stop_time));
You should be denoting the call by reference in the function definition, not the actual call. Since PHP started showing the deprecation errors in version 5.3, I would say it would be a good idea to rewrite the code.
There is no reference sign on a function call - only on function definitions. Function definitions alone are enough to correctly pass the argument by reference. As of PHP 5.3.0, you will get a warning saying that "call-time pass-by-reference" is deprecated when you use
&
infoo(&$a);
.
For example, instead of using:
// Wrong way!
myFunc(&$arg); # Deprecated pass-by-reference argument
function myFunc($arg) { }
Use:
// Right way!
myFunc($var); # pass-by-value argument
function myFunc(&$arg) { }
This is a pretty old thread but the problem is still the same -
I tried multiple things, none of them worked -
C:\Windows\system32\cmd.exe
to the Program and added /c
myscript.bat
to the arguments field.This is what worked for me -
Program/Script Field - cmd
Add Arguments - /c myscript.bat
Start In : Path to myscript.bat
This saves you having to duplicate the link in the tr - just fish it out of the first a.
$(".link-first-found").click(function() {
var href;
href = $(this).find("a").attr("href");
if (href !== "") {
return document.location = href;
}
});
One thing to note - as I had exactly this problem today, depending on your HTML jQuery may or may not parse it that well. jQuery wouldn't parse my HTML into a correct DOM - on smaller XML compliant files it worked fine, but the HTML I had (that would render in a page) wouldn't parse when passed back to an Ajax callback.
In the end I simply searched manually in the string for the tag I wanted, not ideal but did work.
With files we know the size in advance, so just read it all at once!
String result;
File file = ...;
long length = file.length();
if (length < 1 || length > Integer.MAX_VALUE) {
result = "";
Log.w(TAG, "File is empty or huge: " + file);
} else {
try (FileReader in = new FileReader(file)) {
char[] content = new char[(int)length];
int numRead = in.read(content);
if (numRead != length) {
Log.e(TAG, "Incomplete read of " + file + ". Read chars " + numRead + " of " + length);
}
result = new String(content, 0, numRead);
}
catch (Exception ex) {
Log.e(TAG, "Failure reading " + this.file, ex);
result = "";
}
}

You can concatenate it:
SELECT CONVERT(VARCHAR(10), GETDATE(), 104) + ' ' + CONVERT(VARCHAR(8), GETDATE(), 108)
I wasn't aware of a problem with setAttribute
in IE ? However you could directly set the expando property on the node itself:
hiddenInput.id = "uniqueIdentifier";
Depending on what you want to do you could do this:
template<typename Base, typename T>
inline bool instanceof(const T*) {
return std::is_base_of<Base, T>::value;
}
Use:
if (instanceof<BaseClass>(ptr)) { ... }
However, this purely operates on the types as known by the compiler.
Edit:
This code should work for polymorphic pointers:
template<typename Base, typename T>
inline bool instanceof(const T *ptr) {
return dynamic_cast<const Base*>(ptr) != nullptr;
}
Example: http://cpp.sh/6qir
info registers
shows all the registers; info registers eax
shows just the register eax
. The command can be abbreviated as i r
The name
property is marked as protected
. This was added in TypeScript 1.3 and is now firmly established.
The makeSound
method is marked as abstract
, as is the class. You cannot directly instantiate an Animal
now, because it is abstract. This is part of TypeScript 1.6, which is now officially live.
abstract class Animal {
constructor(protected name: string) { }
abstract makeSound(input : string) : string;
move(meters) {
alert(this.name + " moved " + meters + "m.");
}
}
class Snake extends Animal {
constructor(name: string) { super(name); }
makeSound(input : string) : string {
return "sssss"+input;
}
move() {
alert("Slithering...");
super.move(5);
}
}
The old way of mimicking an abstract method was to throw an error if anyone used it. You shouldn't need to do this any more once TypeScript 1.6 lands in your project:
class Animal {
constructor(public name) { }
makeSound(input : string) : string {
throw new Error('This method is abstract');
}
move(meters) {
alert(this.name + " moved " + meters + "m.");
}
}
class Snake extends Animal {
constructor(name) { super(name); }
makeSound(input : string) : string {
return "sssss"+input;
}
move() {
alert("Slithering...");
super.move(5);
}
}
I was facing the same problem, but what I did not realise is that I did not have the MySQL Server installed. You must simply install the MySQL Server.
In order to install the MySQL server, you must run the "MySql Installer" and then press the "Add" button and then choose the "MySQL Server" in the tree.
After doing that, run you workbench again and you'll notice that there'll already be a connection configured. Hopefully, you'll be able to create a new connection or as many connections as you want.
Here's the decoder I've been using for years...
static const char table[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
static const int BASE64_INPUT_SIZE = 57;
BOOL isbase64(char c)
{
return c && strchr(table, c) != NULL;
}
inline char value(char c)
{
const char *p = strchr(table, c);
if(p) {
return p-table;
} else {
return 0;
}
}
int UnBase64(unsigned char *dest, const unsigned char *src, int srclen)
{
*dest = 0;
if(*src == 0)
{
return 0;
}
unsigned char *p = dest;
do
{
char a = value(src[0]);
char b = value(src[1]);
char c = value(src[2]);
char d = value(src[3]);
*p++ = (a << 2) | (b >> 4);
*p++ = (b << 4) | (c >> 2);
*p++ = (c << 6) | d;
if(!isbase64(src[1]))
{
p -= 2;
break;
}
else if(!isbase64(src[2]))
{
p -= 2;
break;
}
else if(!isbase64(src[3]))
{
p--;
break;
}
src += 4;
while(*src && (*src == 13 || *src == 10)) src++;
}
while(srclen-= 4);
*p = 0;
return p-dest;
}

If Your issue is when you touch/tap on android and whole div covered by blue transparent color! Then you need to just change the
CURSOR : POINTER; to CURSOR : DEFAULT;
use mediaQuery to hide in mobile phone/Tablet.
This works for me.
int i = 0; // Counter used to determine when you're at the 3rd gun
for (Gun g : gunList) { // For each gun in your list
System.out.println(g); // Print out the gun
if (i == 2) { // If you're at the third gun
ArrayList<Bullet> bullets = g.getBullet(); // Get the list of bullets in the gun
for (Bullet b : bullets) { // Then print every bullet
System.out.println(b);
}
i++; // Don't forget to increment your counter so you know you're at the next gun
}
In my case this occurred on a test instance of Eclipse run from my main Eclipse session during plugin development. An error caused the gui to disappear, but didn't totally kill it. Hitting the stop button in the console took care of it.
Unless you want to loop through the string and do it "manually" you could solve it like this:
yourString.replace("", " ").trim()
This replaces all "empty substrings" with a space, and then trims off the leading / trailing spaces.
An alternative solution using regular expressions:
yourString.replaceAll(".(?=.)", "$0 ")
Basically it says "Replace all characters (except the last one) with with the character itself followed by a space".

String.replaceAll

syntax)(?=.)
syntax)I tried the following ways in first jQuery, then JavaScript:
jQuery:
window.location.href = $(".contact").attr('href');
$('.contactformone').trigger('click');
This is the best way in JavaScript:
document.getElementById("id").click();
For the best way to do that, try it.
First, find the commit id of the commit that deleted your file. It will give you a summary of commits which deleted files.
git log --diff-filter=D --summary
git checkout 84sdhfddbdddf~1
Note: 84sdhfddbddd
is your commit id
Through this you can easily recover all deleted files.
Well ... Sort of. The easiest is to just use the fact that adjacent string literals are concatenated by the compiler:
const char *text =
"This text is pretty long, but will be "
"concatenated into just a single string. "
"The disadvantage is that you have to quote "
"each part, and newlines must be literal as "
"usual.";
The indentation doesn't matter, since it's not inside the quotes.
You can also do this, as long as you take care to escape the embedded newline. Failure to do so, like my first answer did, will not compile:
const char *text2 = "Here, on the other hand, I've gone crazy \ and really let the literal span several lines, \ without bothering with quoting each line's \ content. This works, but you can't indent.";
Again, note those backslashes at the end of each line, they must be immediately before the line ends, they are escaping the newline in the source, so that everything acts as if the newline wasn't there. You don't get newlines in the string at the locations where you had backslashes. With this form, you obviously can't indent the text since the indentation would then become part of the string, garbling it with random spaces.
Probably the easiest way:
<input type='text' id='abc' value="hel'lo">
I'm 9 years late but a more dynamic way would be
function myFunction {
for i in "$*"; do echo "$i"; done;
}
Pfft! Microseconds! Never solve a problem in microseconds that can be solved in nanoseconds.
Note that the accepted answer:
A better solution is to return True immediately when NAN is found:
import numba
import numpy as np
NAN = float("nan")
@numba.njit(nogil=True)
def _any_nans(a):
for x in a:
if np.isnan(x): return True
return False
@numba.jit
def any_nans(a):
if not a.dtype.kind=='f': return False
return _any_nans(a.flat)
array1M = np.random.rand(1000000)
assert any_nans(array1M)==False
%timeit any_nans(array1M) # 573us
array1M[0] = NAN
assert any_nans(array1M)==True
%timeit any_nans(array1M) # 774ns (!nanoseconds)
and works for n-dimensions:
array1M_nd = array1M.reshape((len(array1M)/2, 2))
assert any_nans(array1M_nd)==True
%timeit any_nans(array1M_nd) # 774ns
Compare this to the numpy native solution:
def any_nans(a):
if not a.dtype.kind=='f': return False
return np.isnan(a).any()
array1M = np.random.rand(1000000)
assert any_nans(array1M)==False
%timeit any_nans(array1M) # 456us
array1M[0] = NAN
assert any_nans(array1M)==True
%timeit any_nans(array1M) # 470us
%timeit np.isnan(array1M).any() # 532us
The early-exit method is 3 orders or magnitude speedup (in some cases). Not too shabby for a simple annotation.
Just in case that the remote file needs your credential to get accessed, you can generate a System.Net.WebClient object using cmdlet New-Object to "Copy File Remotely", like so
$Source = "\\192.168.x.x\somefile.txt"
$Dest = "C:\Users\user\somefile.txt"
$Username = "username"
$Password = "password"
$WebClient = New-Object System.Net.WebClient
$WebClient.Credentials = New-Object System.Net.NetworkCredential($Username, $Password)
$WebClient.DownloadFile($Source, $Dest)
Or if you need to upload a file, you can use UploadFile:
$Dest = "\\192.168.x.x\somefile.txt"
$Source = "C:\Users\user\somefile.txt"
$WebClient.UploadFile($Dest, $Source)
Escape the quotes with backslashes:
printf("She said \"time flies like an arrow, but fruit flies like a banana\".");
There are special escape characters that you can use in string literals, and these are denoted with a leading backslash.

If the stop option is greyed out then your service did not indicate that it was accepting SERVICE_ACCEPT_STOP
when it last called SetServiceStatus
. If you're using .NET, then you need to set the CanStop
property in ServiceBase
.
Of course, if you're accepting stop requests, then you'd better make sure that your service can safely handle those requests, especially if your service is still progressing through its startup code.
Navigation Bar:
navigationController?.navigationBar.barTintColor = UIColor.green
Replace greenColor with whatever UIColor you want, you can use an RGB too if you prefer.
Navigation Bar Text:
navigationController?.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.orange]
Replace orangeColor with whatever color you like.
Tab Bar:
tabBarController?.tabBar.barTintColor = UIColor.brown
Tab Bar Text:
tabBarController?.tabBar.tintColor = UIColor.yellow
On the last two, replace brownColor and yellowColor with the color of your choice.
I have mentioned the configuration changes needed for the increase of heap size in Windows or Linux environments.
Linux:
bin/standalone.conf
Check for the following line,
JAVA_OPTS
and change it accordingly to suit your heap size needs
-Xms1303m: initial heap size in megabytes
-Xmx1303m: maximum heap size in megabytes
JAVA_OPTS="-Xms1024M -Xmx2048M -XX:MaxPermSize=2048M -XX:MaxHeapSize=2048M"
Windows:
bin/standalone.conf.bat
JAVA_OPTS="-Xms1024M -Xmx2048M -XX:MaxPermSize=2048M -XX:MaxHeapSize=2048M"
Now restart the server and it will work without prompting any heap size errors.
For more information you can refer this link below.
Open a command prompt as an Administrator.
Enter slmgr /upk
and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.
Enter slmgr /cpky
and wait for this to complete. This will remove the product key from the registry if it's still there.
Enter slmgr /rearm
and wait for this to complete. This is to reset the Windows activation timers so the new users will be prompted to activate Windows when they put in the key.
This should put the system back to a pre-key state.
Hope this helps you out!
It is a short way but not permanent
first create a container
docker run ..... -p 22022:2222 .....
port 22022 on your host machine will map on 2222, we change the ssh port on container later , then on your container executing the following commands
apt update && apt install openssh-server # install ssh server
passwd #change root password
in file /etc/ssh/sshd_config change these : uncomment Port and change it to 2222
Port 2222
uncomment PermitRootLogin to
PermitRootLogin yes
and finally restart ssh server
/etc/init.d/ssh start
you can login to your container now
ssh -p 2022 root@HostIP
Remember : if you restart the container you need to restart ssh server again
I had the same error. I found the solution for problem now. The problem was client program was finishing before server read the streams.
There are in fact 3 questions in your question :
What JB King has described is correct, but it is a particular, simple version, where in fact he mapped front, middle and bacn to an MVC layer. He mapped M to the back, V to the front, and C to the middle.
For many people, it is just fine, since they come from the ugly world where even MVC was not applied, and you could have direct DB calls in a view.
However in real, complex web applications, you indeed have two or three different layers, called front, middle and back. Each of them may have an associated database and a controller.
The front-end will be visible by the end-user. It should not be confused with the front-office, which is the UI for parameters and administration of the front. The front-end will usually be some kind of CMS or e-commerce Platform (Magento, etc.)
The middle-end is not compulsory and is where the business logics is. It will be based on a PIM, a MDM tool, or some kind of custom database where you enrich your produts or your articles (for CMS). It'll also be the place where you code business functions that need to be shared between differents frontends (for instance between the PC frontend and the API-based mobile application). Sometimes, an ESB or tool like ActiveMQ will be your middle-end
The back-end will be a 3rd layer, surrouding your source database or your ERP. It may be jsut the API wrting to and reading from your ERP. It may be your supplier DB, if you are doing e-commerce. In fact, it really depends on web projects, but it is always a central repository. It'll be accessed either through a DB call, through an API, or an Hibernate layer, or a full-featured back-end application
This description means that answering the other 2 questions is not possible in this thread, as bottlenecks really depend on what your 3 ends contain : what JB King wrote remains true for simple MVC architectures
at the time the question was asked (5 years ago), maybe the MVC pattern was not yet so widely adopted. Now, there is absolutely no reason why the MVC pattern would not be followed and a view would be tied to DB calls. If you read the question "Are there cases where they MUST overlap, and frontend/backend cannot be separated?" in a broader sense, with 3 different components, then there times when the 3 layers architecture is useless of course. Think of a simple personal blog, you'll not need to pull external data or poll RabbitMQ queues.

You'll need to open the workbook to refer to it.
Sub Setwbk()
Dim wbk As Workbook
Set wbk = Workbooks.Open("F:\Quarterly Reports\2012 Reports\New Reports\ _
Master Benchmark Data Sheet.xlsx")
End Sub
* Follow Doug's answer if the workbook is already open. For the sake of making this answer as complete as possible, I'm including my comment on his answer:
Why do I have to "set" it?
Set
is how VBA assigns object variables. Since a Range
and a Workbook
/Worksheet
are objects, you must use Set
with these.
I did mine with EF 6.x like this:
using(var db = new ProFormDbContext())
{
var Action = 1;
var xNTID = "A239333";
var userPlan = db.Database.SqlQuery<UserPlan>(
"AD.usp_UserPlanInfo @Action, @NTID", //, @HPID",
new SqlParameter("Action", Action),
new SqlParameter("NTID", xNTID)).ToList();
}
Don't double up on sqlparameter some people get burned doing this to their variable
var Action = new SqlParameter("@Action", 1); // Don't do this, as it is set below already.
To verify this:-
<div class="Caption">
Model saved
</div>
Write this -
//div[contains(@class, 'Caption') and text()='Model saved']
And to verify this:-
<div id="alertLabel" class="gwt-HTML sfnStandardLeftMargin sfnStandardRightMargin sfnStandardTopMargin">
Save to server successful
</div>
Write this -
//div[@id='alertLabel' and text()='Save to server successful']

You can use us jquery function getJson :
$(function(){
$.getJSON('/api/rest/abc', function(data) {
console.log(data);
});
});
You can get good Time Series graphs in Excel, the way you want, but you have to work with a few quirks.
Be sure to select "Scatter Graph" (with a line option). This is needed if you have non-uniform time stamps, and will scale the X-axis accordingly.
In your data, you need to add a column with the mid-point. Here's what I did with your sample data. (This trick ensures that the data gets plotted at the mid-point, like you desire.)
You can format the x-axis options with this menu. (Chart->Design->Layout)
Select "Axes" and go to Primary Horizontal Axis, and then select "More Primary Horizontal Axis Options"
Set up the options you wish. (Fix the starting and ending points.)
And you will get a graph such as the one below.
You can then tweak many of the options, label the axes better etc, but this should get you started.
Hope this helps you move forward.
In fact, this is a retro-gradation of Python3 as compared to Python2. Certainly, Python2 which uses range() and xrange() is more convenient than Python3 which uses list(range()) and range() respectively. The reason is because the original designer of Python3 is not very experienced, they only considered the use of the range function by many beginners to iterate over a large number of elements where it is both memory and CPU inefficient; but they neglected the use of the range function to produce a number list. Now, it is too late for them to change back already.
If I was to be the designer of Python3, I will:
That should be optimal.
Rand does not get you a random number. It gives you the next number in a sequence generated by a pseudorandom number generator. To get a different sequence every time you start your program, you have to seed the algorithm by calling srand.
A (very bad) way to do it is by passing it the current time:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main() {
srand(time(NULL));
int i, j = 0;
for(i = 0; i <= 10; i++) {
j = rand();
printf("j = %d\n", j);
}
return 0;
}
Why this is a bad way? Because a pseudorandom number generator is as good as its seed, and the seed must be unpredictable. That is why you may need a better source of entropy, like reading from /dev/urandom
.
The issue here is that input()
returns a string in Python 3.x, so when you do your comparison, you are comparing a string and an integer, which isn't well defined (what if the string is a word, how does one compare a string and a number?) - in this case Python doesn't guess, it throws an error.
To fix this, simply call int()
to convert your string to an integer:
int(input(...))
As a note, if you want to deal with decimal numbers, you will want to use one of float()
or decimal.Decimal()
(depending on your accuracy and speed needs).
Note that the more pythonic way of looping over a series of numbers (as opposed to a while
loop and counting) is to use range()
. For example:
def main():
print("Let me Retire Financial Calculator")
deposit = float(input("Please input annual deposit in dollars: $"))
rate = int(input ("Please input annual rate in percentage: %")) / 100
time = int(input("How many years until retirement?"))
value = 0
for x in range(1, time+1):
value = (value * rate) + deposit
print("The value of your account after" + str(x) + "years will be $" + str(value))
You can get the Class reference of any class during run time through the Java Reflection Concept.
Check the Below Code. Explanation is given below
Here is one example that uses returned Class to create an instance of AClass:
package com.xyzws;
class AClass {
public AClass() {
System.out.println("AClass's Constructor");
}
static {
System.out.println("static block in AClass");
}
}
public class Program {
public static void main(String[] args) {
try {
System.out.println("The first time calls forName:");
Class c = Class.forName("com.xyzws.AClass");
AClass a = (AClass)c.newInstance();
System.out.println("The second time calls forName:");
Class c1 = Class.forName("com.xyzws.AClass");
} catch (ClassNotFoundException e) {
// ...
} catch (InstantiationException e) {
// ...
} catch (IllegalAccessException e) {
// ...
}
}
}
The printed output is
The first time calls forName:
static block in AClass
AClass's Constructor
The second time calls forName:
The class has already been loaded so there is no second "static block in AClass"
The Explanation is below
Class.ForName is called to get a Class Object
By Using the Class Object we are creating the new instance of the Class.
Any doubts about this let me know
There are two formats of case expression. You can do CASE
with many WHEN
as;
CASE WHEN Col1 = 1 OR Col3 = 1 THEN 1
WHEN Col1 = 2 THEN 2

My project use ButterKnife and Retro lambda, setting JavaVersion.VERSION_1_8 will not work. It always blames at ButterKnife static interface function until I found this Migrate from Retrolambda
TL;DR
Just add JavaVersion.VERSION_1_8 and completely REMOVE retrolambda from your project. It will build successfully.
IMO the initial commit message line is supposed to be to short, to the point instead of paragraph. So using
git commit -m "<short_message>"
will suffice
After that in order to expand upon the initial commit message we can use
git commit --amend
which will open the vim and then we can enter the explanation for the commit message which in my opinion easier than command line.
With SQL server 2008 and more, using this query:
ALTER TABLE [RecipeInventorys] ALTER COLUMN [RecipeName] varchar(550)
ok, you may use substr in correlation to instr to find the starting position of your string
select
dbms_lob.substr(

dbms_lob.instr(product_details,'NEW.PRODUCT_NO') --offset
)
from my_table
where dbms_lob.instr(product_details,'NEW.PRODUCT_NO')>=1;
wrap all words with quotes:
s/\(\w\+\)/"\1"/g

after:

It looks like there is some small chance that Defender Methods (i.e. default methods) might make it into Java 8. However, as far as I understand them, they only allow the author of an interface
to retroactively extend it, not arbitrary users.
Defender Methods + Interface Injection would then be able to fully implement C#-style extension methods, but AFAICS, Interface Injection isn't even on the Java 8 road-map yet.
$("#foo > div")
selects all divs that are immediate descendants of #foo
once you have the set of children you can either use the size function:
$("#foo > div").size()
or you can use
$("#foo > div").length
Both will return you the same result
sample code below
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("your sheet name");
HSSFRow row = sheet.createRow(0);
cell = row.createCell(0);
cell.setCellValue("A BIG NAME WITH AUTO SIZE FEATURE ENABLED");
//this is crucial
sheet.autoSizeColumn(0);
//argument must be cell number
cell = row.createCell(1);
cell.setCellValue("a big name without auto size feature enabled");
Check the output and go nuts :)
check your tab order and make sure the textbox is set to zero
Yes, we can assign variables from child controller to the variables in parent controller. This is one possible way:
Overview: The main aim of the code, below, is to assign child controller's $scope.variable to parent controller's $scope.assign
Explanation: There are two controllers. In the html, notice that the parent controller encloses the child controller. That means the parent controller will be executed before child controller. So, first setValue() will be defined and then the control will go to the child controller. $scope.variable will be assigned as "child". Then this child scope will be passed as an argument to the function of parent controller, where $scope.assign will get the value as "child"

SNS is a distributed publish-subscribe system. Messages are pushed to subscribers as and when they are sent by publishers to SNS.
SQS is distributed queuing system. Messages are not pushed to receivers. Receivers have to poll or pull messages from SQS. Messages can't be received by multiple receivers at the same time. Any one receiver can receive a message, process and delete it. Other receivers do not receive the same message later. Polling inherently introduces some latency in message delivery in SQS unlike SNS where messages are immediately pushed to subscribers. SNS supports several end points such as email, SMS, HTTP end point and SQS. If you want unknown number and type of subscribers to receive messages, you need SNS.
You don't have to couple SNS and SQS always. You can have SNS send messages to email, SMS or HTTP end point apart from SQS. There are advantages to coupling SNS with SQS. You may not want an external service to make connections to your hosts (a firewall may block all incoming connections to your host from outside).
Your end point may just die because of heavy volume of messages. Email and SMS maybe not your choice of processing messages quickly. By coupling SNS with SQS, you can receive messages at your pace. It allows clients to be offline, tolerant to network and host failures. You also achieve guaranteed delivery. If you configure SNS to send messages to an HTTP end point or email or SMS, several failures to send message may result in messages being dropped.
SQS is mainly used to decouple applications or integrate applications. Messages can be stored in SQS for a short duration of time (maximum 14 days). SNS distributes several copies of messages to several subscribers. For example, let’s say you want to replicate data generated by an application to several storage systems. You could use SNS and send this data to multiple subscribers, each replicating the messages it receives to different storage systems (S3, hard disk on your host, database, etc.).

user@localhost $ screen -t remote-command
user@localhost $ ssh user@target # now inside of a screen session
user@remotehost $ cd /some/directory; program-to-execute &
To detach the screen session: ctrl-a d
To list screen sessions:
screen -ls
To reattach a session:
screen -d -r remote-command
Note that screen can also create multiple shells within each session. A similar effect can be achieved with tmux.
user@localhost $ tmux
user@localhost $ ssh user@target # now inside of a tmux session
user@remotehost $ cd /some/directory; program-to-execute &
To detach the tmux session: ctrl-b d
To list screen sessions:
tmux list-sessions
To reattach a session:
tmux attach <session number>
The default tmux control key, 'ctrl-b', is somewhat difficult to use but there are several example tmux configs that ship with tmux that you can try.
NOTE: You must have the Team Agent or Admin role in App Store Connect to perform any of these tasks. If you are not part of a Team in App Store Connect this probably does not affect you.
Sending push notifications to an iOS application requires creating encyption keys. In the past this was a cumbersome process that used SSL keys and certificates. Each SSL certificate was specific to a single iOS application. In 2016 Apple introduced a new authentication key mechanism that is more reliable and easier to use. The new authentication keys are more flexible, simple to maintain and apply to more than on iOS app.
Even though it has been years since authentication keys were introduced not every service supports them. FireBase and Amazon Pinpoint support authentication keys. Amazon SNS, Urban Airship, Twilio, and LeanPlum do not. Many open source software packages do not yet support authentication keys.
To create the required SSL certificate and export it as PEM file containing public and private keys:
If you already have the SSL certificate set up for the app in the Apple Developer Center website you can skip ahead to Convert the certificate to PEM format. Keep in mind that you will run into problems if you do not also have the private key that was generated on the Mac that created the signing request that was uploaded to Apple.
Read on to see how to avoid losing track of that private key.
Xcode does not control certificates or keys for push notifications. To create keys and enable push notifications for an app you must go to the Apple Developer Center website. The Certificates, Identifiers & Profiles section of your account controls App IDs and certificates.
To access certificates and profiles you must either have a paid Apple Developer Program membership or be part of a Team that does.
Apps that use push notifications can not use wildcard App IDs or provisioning profiles. Each app requires you to set up an App ID record in the Apple Developer Center portal to enable push notifications.
Creating SSL certificates for push notifications is a process of several tasks. Each task has several steps. All of these are necessary to export the keys in P12 or PEM format. Review the steps before proceeding.
To create a certificate you will need to make a Certificate Signing Request (CSR) on a Mac and upload it to Apple.
Later if you need to export this certificate as a pkcs12 (aka p12) file you will need to use the keychain from the same Mac. When the signing request is created Keychain Access generates a set of keys in the default keychain. These keys are necessary for working with the certificate Apple will create from the signing request.
It is a good practice to have a separate keychain specifically for credentials used for development. If you do this make sure this keychain is set to be the default before using Certificate Assistant.
When creating the Certificate Signing Request the Certificate Assistant generates two encryption keys in the default keychain. It is important to make the development keychain the default so the keys are in the right keychain.
Creating the signing request generated a pair of keys. Before the signing request is uploaded verify that the development keychain has the keys. Their names will be the same as the Common Name used in the signing request.
Once the Certicate Signing Request is created upload it to the Apple Developer Center. Apple will create the push notification certificate from the signing request.
Your development keychain should now show the push certificate with a private key under My Certificates in Keychain Access:
At this point the development keychain should be backed up. Many teams keep their push certificates on secure USB drives, commit to internal version control or use a backup solution like Time Machine. The development keychain can be shared between different team members because it does not contain any personal code signing credentials.
Keychain files are located in
~/Library/Keychains
.
Some third party push services require certificates in Privacy Enhanced Mail (PEM) format, while others require Public-Key Cryptography Standards #12 (PKCS12 or P12). The certificate downloaded from Apple can be used to export certificates in these formats - but only if you have kept the private key.
Enable NSZombieEnabled to know which object is being released and then accessed.

Lots of interesting answers to this "old" question, even some relatively new answers, but I didn't find any that mention this....
When used properly and with care, consistent use of
alloca()
(perhaps application-wide) to handle small variable-length allocations (or C99 VLAs, where available) can lead to lower overall stack growth than an otherwise equivalent implementation using oversized local arrays of fixed length. Soalloca()
may be good for your stack if you use it carefully.
I found that quote in.... OK, I made that quote up. But really, think about it....
@j_random_hacker is very right in his comments under other answers: Avoiding the use of alloca()
in favor of oversized local arrays does not make your program safer from stack overflows (unless your compiler is old enough to allow inlining of functions that use alloca()
in which case you should upgrade, or unless you use alloca()
inside loops, in which case you should... not use alloca()
inside loops).
I've worked on desktop/server environments and embedded systems. A lot of embedded systems don't use a heap at all (they don't even link in support for it), for reasons that include the perception that dynamically allocated memory is evil due to the risks of memory leaks on an application that never ever reboots for years at a time, or the more reasonable justification that dynamic memory is dangerous because it can't be known for certain that an application will never fragment its heap to the point of false memory exhaustion. So embedded programmers are left with few alternatives.
alloca()
(or VLAs) may be just the right tool for the job.I've seen time & time again where a programmer makes a stack-allocated buffer "big enough to handle any possible case". In a deeply nested call tree, repeated use of that (anti-?)pattern leads to exaggerated stack use. (Imagine a call tree 20 levels deep, where at each level for different reasons, the function blindly over-allocates a buffer of 1024 bytes "just to be safe" when generally it will only use 16 or less of them, and only in very rare cases may use more.) An alternative is to use alloca()
or VLAs and allocate only as much stack space as your function needs, to avoid unnecessarily burdening the stack. Hopefully when one function in the call tree needs a larger-than-normal allocation, others in the call tree are still using their normal small allocations, and the overall application stack usage is significantly less than if every function blindly over-allocated a local buffer.
alloca()
...Based on other answers on this page, it seems that VLAs should be safe (they don't compound stack allocations if called from within a loop), but if you're using alloca()
, be careful not to use it inside a loop, and make sure your function can't be inlined if there's any chance it might be called within another function's loop.
The npm view <pkg> version
prints the last version by release date. That might very well be an hotfix release for a older stable branch at times.
The solution is to list all versions and fetch the last one by version number
$ npm view <pkg> versions --json | jq -r '.[-1]'
Or with awk instead of jq:
$ npm view <pkg> --json | awk '/"$/{print gensub("[ \"]", "", "G")}'
You have two boxes, left and right, for each label/input pair. Both boxes are in one row and have fixed width. Now, you just have to make label text float to the right with text-align: right;
Here's a simple example:
JSP is s presentation framework, and is generally not supposed to contain any program logic in it. As skaffman suggested, use pure servlets, or any MVC web framework in order to achieve what you want.
The ALL_DIRECTORIES
data dictionary view will have information about all the directories that you have access to. That includes the operating system path
SELECT owner, directory_name, directory_path
FROM all_directories
Well you could attach a click or mousemove event to the document body that resets a timer. Have a function that you call at timed intervals that checks if the timer is over a specified time (like 1000 millis) and start your preloading.
This solution sort by Col1 and group by Col2. Then extract value of Col2 and display it in a mbox.
var grouped = from DataRow dr in dt.Rows orderby dr["Col1"] group dr by dr["Col2"];
string x = "";
foreach (var k in grouped) x += (string)(k.ElementAt(0)["Col2"]) + Environment.NewLine;
MessageBox.Show(x);
I found the links and tips under this question to be helpful.
They are access modifiers and help us implement Encapsulation (or information hiding). They tell the compiler which other classes should have access to the field or method being defined.
private
- Only the current class will have access to the field or method.
protected
- Only the current class and subclasses (and sometimes also same-package classes) of this class will have access to the field or method.
public
- Any class can refer to the field or call the method.
This assumes these keywords are used as part of a field or method declaration within a class definition.
One thing you should know is $ prefix refers to an Angular Method, $$ prefixes refers to angular methods that you should avoid using.
below is an example template and its controllers, we'll explore how $broadcast/$on can help us achieve what we want.
<div ng-controller="FirstCtrl">
<input ng-model="name"/>
<button ng-click="register()">Register </button>
</div>
<div ng-controller="SecondCtrl">
Registered Name: <input ng-model="name"/>
</div>
The controllers are
app.controller('FirstCtrl', function($scope){
$scope.register = function(){
}
});
app.controller('SecondCtrl', function($scope){
});
My question to you is how do you pass the name to the second controller when a user clicks register? You may come up with multiple solutions but the one we're going to use is using $broadcast and $on.
$broadcast vs $emit
Which should we use? $broadcast will channel down to all the children dom elements and $emit will channel the opposite direction to all the ancestor dom elements.
The best way to avoid deciding between $emit or $broadcast is to channel from the $rootScope and use $broadcast to all its children. Which makes our case much easier since our dom elements are siblings.
Adding $rootScope and lets $broadcast
app.controller('FirstCtrl', function($rootScope, $scope){
$scope.register = function(){
$rootScope.$broadcast('BOOM!', $scope.name)
}
});
Note we added $rootScope and now we're using $broadcast(broadcastName, arguments). For broadcastName, we want to give it a unique name so we can catch that name in our secondCtrl. I've chosen BOOM! just for fun. The second arguments 'arguments' allows us to pass values to the listeners.
Receiving our broadcast
In our second controller, we need to set up code to listen to our broadcast
app.controller('SecondCtrl', function($scope){
$scope.$on('BOOM!', function(events, args){
console.log(args);
$scope.name = args; //now we've registered!
})
});
It's really that simple. Live Example
Other ways to achieve similar results
Try to avoid using this suite of methods as it is neither efficient nor easy to maintain but it's a simple way to fix issues you might have.
You can usually do the same thing by using a service or by simplifying your controllers. We won't discuss this in detail but I thought I'd just mention it for completeness.
Lastly, keep in mind a really useful broadcast to listen to is '$destroy' again you can see the $ means it's a method or object created by the vendor codes. Anyways $destroy is broadcasted when a controller gets destroyed, you may want to listen to this to know when your controller is removed.
use Illuminate\Support\Facades\Auth;
In class:
protected $user;
This code it`s works for me
In construct:
$this->user = User::find(Auth::user()->id);
In function:
$this->user->id;
$this->user->email;
etc..
Adam Luter gave me the idea for this, but it actually turned out to be really simple:
img {
width: 75px;
height: auto;
}
IE6 now scales the image fine and this seems to be what all the other browsers use by default.
Thanks for both the answers though!
In Java terms, Scala's Seq
would be Java's List
, and Scala's List
would be Java's LinkedList
.
Note that Seq
is a trait
, which is equivalent to Java's interface
, but with the equivalent of up-and-coming defender methods. Scala's List
is an abstract class that is extended by Nil
and ::
, which are the concrete implementations of List
.
So, where Java's List
is an interface
, Scala's List
is an implementation.
Beyond that, Scala's List
is immutable, which is not the case of LinkedList
. In fact, Java has no equivalent to immutable collections (the read only thing only guarantees the new object cannot be changed, but you still can change the old one, and, therefore, the "read only" one).
Scala's List
is highly optimized by compiler and libraries, and it's a fundamental data type in functional programming. However, it has limitations and it's inadequate for parallel programming. These days, Vector
is a better choice than List
, but habit is hard to break.
Seq
is a good generalization for sequences, so if you program to interfaces, you should use that. Note that there are actually three of them: collection.Seq
, collection.mutable.Seq
and collection.immutable.Seq
, and it is the latter one that is the "default" imported into scope.
There's also GenSeq
and ParSeq
. The latter methods run in parallel where possible, while the former is parent to both Seq
and ParSeq
, being a suitable generalization for when parallelism of a code doesn't matter. They are both relatively newly introduced, so people doesn't use them much yet.

One thing you could change in your code very easily is the fontsize
you are using for the titles. However, I am going to assume that you don't just want to do that!
Some alternatives to using fig.subplots_adjust(top=0.85)
:
Usually tight_layout()
does a pretty good job at positioning everything in good locations so that they don't overlap. The reason tight_layout()
doesn't help in this case is because tight_layout()
does not take fig.suptitle() into account. There is an open issue about this on GitHub: https://github.com/matplotlib/matplotlib/issues/829 [closed in 2014 due to requiring a full geometry manager - shifted to https://github.com/matplotlib/matplotlib/issues/1109 ].
If you read the thread, there is a solution to your problem involving GridSpec
. The key is to leave some space at the top of the figure when calling tight_layout
, using the rect
kwarg. For your problem, the code becomes:
Using GridSpec
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.gridspec as gridspec
f = np.random.random(100)
g = np.random.random(100)
fig = plt.figure(1)
gs1 = gridspec.GridSpec(1, 2)
ax_list = [fig.add_subplot(ss) for ss in gs1]
ax_list[0].plot(f)
ax_list[0].set_title('Very Long Title 1', fontsize=20)
ax_list[1].plot(g)
ax_list[1].set_title('Very Long Title 2', fontsize=20)
fig.suptitle('Long Suptitle', fontsize=24)
gs1.tight_layout(fig, rect=[0, 0.03, 1, 0.95])
plt.show()
The result:
Maybe GridSpec
is a bit overkill for you, or your real problem will involve many more subplots on a much larger canvas, or other complications. A simple hack is to just use annotate()
and lock the coordinates to the 'figure fraction'
to imitate a suptitle
. You may need to make some finer adjustments once you take a look at the output, though. Note that this second solution does not use tight_layout()
.
Simpler solution (though may need to be fine-tuned)
fig = plt.figure(2)
ax1 = plt.subplot(121)
ax1.plot(f)
ax1.set_title('Very Long Title 1', fontsize=20)
ax2 = plt.subplot(122)
ax2.plot(g)
ax2.set_title('Very Long Title 2', fontsize=20)
# fig.suptitle('Long Suptitle', fontsize=24)
# Instead, do a hack by annotating the first axes with the desired
# string and set the positioning to 'figure fraction'.
fig.get_axes()[0].annotate('Long Suptitle', (0.5, 0.95),
xycoords='figure fraction', ha='center',
fontsize=24
)
plt.show()
The result:
[Using Python
2.7.3 (64-bit) and matplotlib
1.2.0]
this also works:
$url = "http://www.some-url";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$xmlresponse = curl_exec($ch);
$xml=simplexml_load_string($xmlresponse);
then I just run a forloop to grab the stuff from the nodes.
like this:`
for($i = 0; $i < 20; $i++) {
$title = $xml->channel->item[$i]->title;
$link = $xml->channel->item[$i]->link;
$desc = $xml->channel->item[$i]->description;
$html .="<div><h3>$title</h3>$link<br />$desc</div><hr>";
}
echo $html;
***note that your node names will differ, obviously..and your HTML might be structured differently...also your loop might be set to higher or lower amount of results.
Adding this snippet, simple elegant in Swift works for me in iOS8 :)

func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
cell.preservesSuperviewLayoutMargins = false
cell.layoutMargins = UIEdgeInsetsZero
}

In general I try to have only a single exit point from a function. There are times, however, that doing so actually ends up creating a more complex function body than is necessary, in which case it's better to have multiple exit points. It really has to be a "judgement call" based on the resulting complexity, but the goal should be as few exit points as possible without sacrificing complexity and understandability.
You need to use brackets when using the fileExists
step in an if
condition or assign the returned value to a variable
Using variable:
def exists = fileExists 'file'
if (exists) {
echo 'Yes'
} else {
echo 'No'
}
Using brackets:
if (fileExists('file')) {
echo 'Yes'
} else {
echo 'No'
}
One thing to note:
I have had issues with websockets and corporate firewalls. (Using HTTPS helps but not always.)
See https://github.com/LearnBoost/socket.io/wiki/Socket.IO-and-firewall-software https://github.com/sockjs/sockjs-client/issues/94
I assume there aren't as many issues with Server-Sent Events. But I don't know.
That said, WebSockets are tons of fun. I have a little web game that uses websockets (via Socket.IO) (http://minibman.com)
You can simply use,

console.log('Weekday',weekday);
Question#1 - These are the only way to handle view clicks.
Question#2 -
Option#1/Option#4 - There's not much difference between option#1 and option#4. The only difference I see is in one case activity is implementing the OnClickListener, whereas, in the other case, there'd be an anonymous implementation.
Option#2 - In this method an anonymous class will be generated. This method is a bit cumborsome, as, you'd need to do it multiple times, if you have multiple buttons. For Anonymous classes, you have to be careful for handling memory leaks.
Option#3 - Though, this is a easy way. Usually, Programmers try not to use any method until they write it, and hence this method is not widely used. You'd see mostly people use Option#4. Because it is cleaner in term of code.
If you have multiple versions of a package / module, you need to be using virtualenv (emphasis mine):
virtualenv
is a tool to create isolated Python environments.The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications? If you install everything into
/usr/lib/python2.7/site-packages
(or whatever your platform’s standard location is), it’s easy to end up in a situation where you unintentionally upgrade an application that shouldn’t be upgraded.Or more generally, what if you want to install an application and leave it be? If an application works, any change in its libraries or the versions of those libraries can break the application.
Also, what if you can’t install packages into the global
site-packages
directory? For instance, on a shared host.In all these cases,
virtualenv
can help you. It creates an environment that has its own installation directories, that doesn’t share libraries with other virtualenv environments (and optionally doesn’t access the globally installed libraries either).
That's why people consider insert(0,
to be wrong -- it's an incomplete, stopgap solution to the problem of managing multiple environments.
Another option can be using built in angular formatDate function. I am assuming that you are using reactive forms. Here todoDate
is a date input field in template.
import {formatDate} from '@angular/common';
this.todoForm.controls.todoDate.setValue(formatDate(this.todo.targetDate, 'yyyy-MM-dd', 'en-US'));
The javadocs for Scanner answer your question
A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace.
You might change the default whitespace pattern the Scanner is using by doing something like
Scanner s = new Scanner();
s.useDelimiter("\n");
In ES6:
class MyError extends Error {
constructor(message) {
super(message);
this.name = 'MyError';
}
}
It seems if you have a strongly typed view you need to change the ID of the dropdown so that it is NOT the name of a property on the inherrited class. You then need to put some logic in your edit (POST) method to pull off the selected value from the FORMCollection and put it on to your instance before committing your changes.
This is certainly a little strange, but i tried it and it works.
So if you class has a field called CountryId say, and you're displaying a list of country names, make the dropdown have an id of CountryName rather than CountryId, then in the post, you can do something with Collection["CountryName"].
The modern approach is with the java.time classes. These supplant the troublesome old legacy date-time classes such as Date
, Calendar
, and SimpleDateFormat
.
Parse as a ZonedDateTime
.
String input = "Mon Jun 18 00:00:00 IST 2012";
DateTimeFormatter f = DateTimeFormatter.ofPattern( "E MMM dd HH:mm:ss z uuuu" )
.withLocale( Locale.US );
ZonedDateTime zdt = ZonedDateTime.parse( input , f );
Extract a date-only object, a LocalDate
, without any time-of-day and without any time zone.
LocalDate ld = zdt.toLocalDate();
DateTimeFormatter fLocalDate = DateTimeFormatter.ofPattern( "dd/MM/uuuu" );
String output = ld.format( fLocalDate) ;
Dump to console.
System.out.println( "input: " + input );
System.out.println( "zdt: " + zdt );

Your format is a poor choice for data exchange: hard to read by human, hard to parse by computer, uses non-standard 3-4 letter zone codes, and assumes English.
Instead use the standard ISO 8601 formats whenever possible. The java.time classes use ISO 8601 formats by default when parsing/generating date-time values.
Specify a proper time zone name in the format of continent/region
, such as America/Montreal
, Africa/Casablanca
, or Pacific/Auckland
. Never use the 3-4 letter abbreviation such as EST
or IST
as they are not true time zones, not standardized, and not even unique(!). For example, your use of IST
may be Irish Standard Time, Israel Standard Time (as interpreted by java.time, seen above), or India Standard Time.
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
>>> a = [5, 7, 11, 4, 5]
>>> for n,k in enumerate(a[:-1]):
... print a[n],a[n+1]
...
5 7
7 11
11 4
4 5
You should now use the .on()
function to bind events.

Method 1 : Using jQuery Ajax Get call (partial page update).
Suitable for when you need to retrieve jSon data from database.
Controller's Action Method
[HttpGet]
public ActionResult Foo(string id)
{
var person = Something.GetPersonByID(id);
return Json(person, JsonRequestBehavior.AllowGet);
}
Jquery GET
function getPerson(id) {
$.ajax({
url: '@Url.Action("Foo", "SomeController")',
type: 'GET',
dataType: 'json',
// we set cache: false because GET requests are often cached by browsers
// IE is particularly aggressive in that respect
cache: false,
data: { id: id },
success: function(person) {
$('#FirstName').val(person.FirstName);
$('#LastName').val(person.LastName);
}
});
}
Person class
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
}
Method 2 : Using jQuery Ajax Post call (partial page update).
Suitable for when you need to do partial page post data into database.
Post method is also same like above just replace [HttpPost]
on Action method and type as post
for jquery method.
For more information check Posting JSON Data to MVC Controllers Here
Method 3 : As a Form post scenario (full page update).
Suitable for when you need to save or update data into database.
View
@using (Html.BeginForm("SaveData","ControllerName", FormMethod.Post))
{
@Html.TextBoxFor(model => m.Text)
<input type="submit" value="Save" />
}
Action Method
[HttpPost]
public ActionResult SaveData(FormCollection form)
{
// Get movie to update
return View();
}
Method 4 : As a Form Get scenario (full page update).
Suitable for when you need to Get data from database
Get method also same like above just replace [HttpGet]
on Action method and FormMethod.Get
for View's form method.
I hope this will help to you.
It looks like you are trying to read an object from JSON that actually describes an array. Java objects are mapped to JSON objects with curly braces {}
but your JSON actually starts with square brackets []
designating an array.
What you actually have is a List<product>
To describe generic types, due to Java's type erasure, you must use a TypeReference
. Your deserialization could read: myProduct = objectMapper.readValue(productJson, new TypeReference<List<product>>() {});
A couple of other notes: your classes should always be PascalCased. Your main method can just be public static void main(String[] args) throws Exception
which saves you all the useless catch
blocks.
You could use this one as well with kramdown:
markdown
![drawing](drawing.jpg)
{:.some-css-class style="width: 200px"}
or
markdown
![drawing](drawing.jpg)
{:.some-css-class width="200"}
This way you can directly add arbitrary attributes to the last html element. To add classes there is a shortcut .class.secondclass.
Unless you call some function this is not at all trivial. (And, seriously, there's no real difference in complexity between calling printf and calling a win32 api function.)
Even DOS int 21h is really just a function call, even if its a different API.
If you want to do it without help you need to talk to your video hardware directly, likely writing bitmaps of the letters of "Hello world" into a framebuffer. Even then the video card is doing the work of translating those memory values into DisplayPort/HDMI/DVI/VGA signals.
Note that, really, none of this stuff all the way down to the hardware is any more interesting in ASM than in C. A "hello world" program boils down to a function call. One nice thing about ASM is that you can use any ABI you want fairly easily; you just need to know what that ABI is.
Now I got it working (after removing the header
command). I think the problem was that the encoding of the php file was in ISO-8859-1. I set it to UTF-8 without BOM. I thought I already have done that, but perhaps I made an additional undo.
Furthermore, I used SET NAMES 'utf8'
for the database. Now it is also correct in the database.
Be carefully though. If you return Collections.emptyList()
and then try to do some changes with it like add()
or smth like that, u will have an UnsupportedOperationException()
because Collections.emptyList()
returns an immutable object.
Well, for one thing your epression can be simplified:
$("#pDetails").attr("style")
since there should only be one element for any given ID and the ID selector will be much faster than the attribute id selector you're using.
If you just want to return the display value or something, use css():
$("#pDetails").css("display")
If you want to search for elements that have display none, that's a lot harder to do reliably. This is a rough example that won't be 100%:
$("[style*='display: none']")
but if you just want to find things that are hidden, use this:
$(":hidden")
fstream
s are not slower than C streams, per se, but they use more CPU (especially if buffering is not properly configured). When a CPU saturates, it limits the I/O rate.
At least the MSVC 2015 implementation copies 1 char at a time to the output buffer when a stream buffer is not set (see streambuf::xsputn
). So make sure to set a stream buffer (>0).
I can get a write speed of 1500MB/s (the full speed of my M.2 SSD) with fstream
using this code:
#include <iostream>
#include <fstream>
#include <chrono>
#include <memory>
#include <stdio.h>
#ifdef __linux__
#include <unistd.h>
#endif
using namespace std;
using namespace std::chrono;
const size_t sz = 512 * 1024 * 1024;
const int numiter = 20;
const size_t bufsize = 1024 * 1024;
int main(int argc, char**argv)
{
unique_ptr<char[]> data(new char[sz]);
unique_ptr<char[]> buf(new char[bufsize]);
for (size_t p = 0; p < sz; p += 16) {
memcpy(&data[p], "BINARY.DATA.....", 16);
}
unlink("file.binary");
int64_t total = 0;
if (argc < 2 || strcmp(argv[1], "fopen") != 0) {
cout << "fstream mode\n";
ofstream myfile("file.binary", ios::out | ios::binary);
if (!myfile) {
cerr << "open failed\n"; return 1;
}
myfile.rdbuf()->pubsetbuf(buf.get(), bufsize); // IMPORTANT
for (int i = 0; i < numiter; ++i) {
auto tm1 = high_resolution_clock::now();
myfile.write(data.get(), sz);
if (!myfile)
cerr << "write failed\n";
auto tm = (duration_cast<milliseconds>(high_resolution_clock::now() - tm1).count());
cout << tm << " ms\n";
total += tm;
}
myfile.close();
}
else {
cout << "fopen mode\n";
FILE* pFile = fopen("file.binary", "wb");
if (!pFile) {
cerr << "open failed\n"; return 1;
}
setvbuf(pFile, buf.get(), _IOFBF, bufsize); // NOT important
auto tm1 = high_resolution_clock::now();
for (int i = 0; i < numiter; ++i) {
auto tm1 = high_resolution_clock::now();
if (fwrite(data.get(), sz, 1, pFile) != 1)
cerr << "write failed\n";
auto tm = (duration_cast<milliseconds>(high_resolution_clock::now() - tm1).count());
cout << tm << " ms\n";
total += tm;
}
fclose(pFile);
auto tm2 = high_resolution_clock::now();
}
cout << "Total: " << total << " ms, " << (sz*numiter * 1000 / (1024.0 * 1024 * total)) << " MB/s\n";
}
I tried this code on other platforms (Ubuntu, FreeBSD) and noticed no I/O rate differences, but a CPU usage difference of about 8:1 (fstream
used 8 times more CPU). So one can imagine, had I a faster disk, the fstream
write would slow down sooner than the stdio
version.
If Nothing else works try following
if (environment.production) {
// there is no need of this if block, angular internally creates following code structure when it sees --prod
// but at the time of writting this code, else block was not working in the production mode and NgModule metadata
// not found for AppModule error was coming at run time, added follow code to fix that, it can be removed probably

First give the link of logout.php
page in that logout button.In that page make the code which is given below:
Here is the code:
<?php
session_start();
session_destroy();
?>
When the session has started, the session for the last/current user has been started, so don't need to declare the username. It will be deleted automatically by the session_destroy method.
Disable xdebug only for certain PHP version or sapi. On this case PHP 7.2 fpm
sudo phpdismod -v 7.2 -s fpm xdebug
sudo service php7.2-fpm nginx restart
You can set height and width like this:
myGraphView.setLayoutParams(new LayoutParams(width, height));
If you are using new androidx Material design library com.google.android.material
then you can use colorstatelist to control hint text color in focused, hovered and default state as follows. (inspired by this)
In res/color/text_input_box_stroke.xml
put something like the following:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#fcc" android:state_focused="true"/>
<item android:color="#cfc" android:state_hovered="true"/>
<item android:color="#ccf"/>
</selector>
Then in your styles.xml
you would put:
<style name="MtTILStyle" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense">
<item name="boxStrokeColor">@color/text_input_box_stroke</item>
<item name="hintTextColor">@color/text_input_box_stroke</item>
</style>
Finally indicate your style in the actual TextInputLayout
For some reason you also need to set android:textColorHint
for default text color of hint:
<com.google.android.material.textfield.TextInputLayout
android:id="@+id/my_layout_id"
style="@style/LoginTextInputLayoutStyle"
android:textColorHint="#ccf"
...
It depends on what you are looking for, as they each have their pros and cons.
Spring.NET
is the most mature as it comes out of Spring from the Java world. Spring has a very rich set of framework libraries that extend it to support Web, Windows, etc.Castle Windsor
is one of the most widely used in the .NET platform and has the largest ecosystem, is highly configurable / extensible, has custom lifetime management, AOP support, has inherent NHibernate support and is an all around awesome container. Windsor is part of an entire stack which includes Monorail, Active Record, etc. NHibernate itself builds on top of Windsor.Structure Map
has very rich and fine grained configuration through an internal DSL.Autofac
is an IoC container of the new age with all of it's inherent functional programming support. It also takes a different approach on managing lifetime than the others. Autofac is still very new, but it pushes the bar on what is possible with IoC.Ninject
I have heard is more bare bones with a less is more approach (heard not experienced).Unity
is: it's from and supported by Microsoft (p&p). Unity has very good performance, and great documentation. It is also highly configurable. It doesn't have all the bells and whistles of say Castle / Structure Map.So in summary, it really depends on what is important to you. I would agree with others on going and evaluating and seeing which one fits. The nice thing is you have a nice selection of donuts rather than just having to have a jelly one.
I see permutation has been suggested. In fact it can be made into one line:
>>> A = np.random.randint(5, size=(10,3))
>>> np.random.permutation(A)[:2]
array([[0, 3, 0],
[3, 1, 2]])
There's a third (and potentially much easier) option. If you want to spin up multiple instances of a single program, using a Unix-style command processor like Xargs or GNU Parallel can make that a fairly straightforward process.
There's a win32 Xargs clone called PPX2 that makes this fairly straightforward.
For instance, if you wanted to transcode a directory of video files, you could run the command:
dir /b *.mpg |ppx2 -P 4 -I {} -L 1 ffmpeg.exe -i "{}" -quality:v 1 "{}.mp4"
Picking this apart, dir /b *.mpg
grabs a list of .mpg files in my current directory, the |
operator pipes this list into ppx2, which then builds a series of commands to be executed in parallel; 4 at a time, as specified here by the -P 4
operator. The -L 1
operator tells ppx2 to only send one line of our directory listing to ffmpeg at a time.
After that, you just write your command line (ffmpeg.exe -i "{}" -quality:v 1 "{}.mp4"
), and {}
gets automatically substituted for each line of your directory listing.
It's not universally applicable to every case, but is a whole lot easier than using the batch file workarounds detailed above. Of course, if you're not dealing with a list of files, you could also pipe the contents of a textfile or any other program into the input of pxx2.
Well this is simple answer you want.

Building on @JustinBarber's example and noting @eric.frederich's comment, if you want to format negative values like -$1,000.00
rather than $-1,000.00
and don't want to use locale
:
def as_currency(amount):
if amount >= 0:
return '${:,.2f}'.format(amount)
else:
return '-${:,.2f}'.format(-amount)
position: relative act as a parent element position: absolute act a child of relative position. you can see the below example
.postion-element{
position:relative;
width:200px;
height:200px;
background-color:green;
}
.absolute-element{
position:absolute;
top:10px;
left:10px;
background-color:blue;
}
You could also use a session for passing small bits of info. You will need to have session_start(); at the top of the PHP pages that use the session else the variables will not be accessable
page1.php
<?php
session_start();
$_SESSION['superhero'] = "batman";
?>
<a href="page2.php" title="">Go to the other page</a>
page2.php
<?php
session_start(); // this NEEDS TO BE AT THE TOP of the page before any output etc
echo $_SESSION['superhero'];
?>
Each directive's pre-link
function is called whenever a new related element is instantiated.
As seen previously in the compilation order section, pre-link
functions are called parent-then-child, whereas post-link
functions are called child-then-parent
.
The pre-link
function is rarely used, but can be useful in special scenarios; for example, when a child controller registers itself with the parent controller, but the registration has to be in a parent-then-child
fashion (ngModelController
does things this way).
Gently reminder about using prop()
, example:
if ($("#checkbox1").prop('checked')) {
isDelete = 1;
} else {
isDelete = 0;
}
The function above is used to check if checkbox1 is checked or not, if checked: return 1; if not: return 0. Function prop() used here as a GET function.
if ($("#checkbox1").prop('checked', true)) {
isDelete = 1;
} else {
isDelete = 0;
}
The function above is used to set checkbox1 to be checked and ALWAYS return 1. Now function prop() used as a SET function.
Don't mess up.
P/S: When I'm checking Image src property. If the src is empty, prop return the current URL of the page (wrong), and attr return empty string (right).
Basically you can create a regex to fulfil your needs and then assign that pattern to your input field.
Or for a more direct approach:
<input type="number" require ng-pattern="<your regex here>">

ftplib now supports context managers so I guess it can be made even easier
from ftplib import FTP
from pathlib import Path
file_path = Path('kitten.jpg')
with FTP('server.address.com', 'USER', 'PWD') as ftp, open(file_path, 'rb') as file:
ftp.storbinary(f'STOR {file_path.name}', file)
No need to close the file or the session
One option is http://davidbau.com/seedrandom which is a seedable RC4-based Math.random() drop-in replacement with nice properties.
You try with this string connection
Server=.\SQLExpress;AttachDbFilename=|DataDirectory|Database1.mdf;Database=dbname; Trusted_Connection=Yes;
You can't set a favicon from CSS - if you want to do this explicitly you have to do it in the markup as you described.
Most browsers will, however, look for a favicon.ico
file on the root of the web site - so if you access http://example.com most browsers will look for http://example.com/favicon.ico automatically.
Its blank because you are writing to file
. you should write to output
using php://output
instead and also send header information to indicate that it's csv.
Example
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="sample.csv"');
$data = array(
'aaa,bbb,ccc,dddd',
'123,456,789',
'"aaa","bbb"'
);
$fp = fopen('php://output', 'wb');
foreach ( $data as $line ) {
$val = explode(",", $line);
fputcsv($fp, $val);
}
fclose($fp);
maybe I'd go by this.
SQL = SELECT REPLACE(myColumn, '""', '\'') FROM myTable
I used singlequotes because that's the one that registers string expressions in MySQL, or so I believe.
Hope that helps.
You may achieve this using pandas as well:
import pandas as pd
pd.to_datetime('Mon Feb 15 2010', format='%a %b %d %Y').strftime('%d/%m/%Y')
Output:
'15/02/2010'
You may apply pandas approach for different datatypes as:
import pandas as pd
import numpy as np
def reformat_date(date_string, old_format, new_format):
return pd.to_datetime(date_string, format=old_format, errors='ignore').strftime(new_format)
date_string = 'Mon Feb 15 2010'
date_list = ['Mon Feb 15 2010', 'Wed Feb 17 2010']
date_array = np.array(date_list)
date_series = pd.Series(date_list)
old_format = '%a %b %d %Y'
new_format = '%d/%m/%Y'
print(reformat_date(date_string, old_format, new_format))
print(reformat_date(date_list, old_format, new_format).values)
print(reformat_date(date_array, old_format, new_format).values)
print(date_series.apply(lambda x: reformat_date(x, old_format, new_format)).values)
Output:
15/02/2010
['15/02/2010' '17/02/2010']
['15/02/2010' '17/02/2010']
['15/02/2010' '17/02/2010']
You can get the id of the last transaction by running lastInsertId() method on the connection object($conn).
Like this $lid = $conn->lastInsertId();

Now android studio is provide a plugin Image Asset, which will be generate icon in all required drawbale folder
Image Asset Studio helps you create various types of icons at different densities and shows you exactly where they'll be placed in your project. It includes tools for adjusting your icons and adding backdrops, all while displaying the result in a preview pane, so they appear exactly as you intended. These tools can dramatically streamline the icon design and import process.
You can access Image Asset by click new> click on Image Asset option and it will be show window like this :-
You can do this with the "rebase" command. Let's call the branches "main" and "feature":
git checkout feature
git rebase main
The rebase command will replay all of the commits on "feature" as one commit with a parent equal to "main".
You might want to run git merge main
before git rebase main
if "main" has changed since "feature" was created (or since the most recent merge). That way, you still have your full history in case you had a merge conflict.
After the rebase, you can merge your branch to main, which should result in a fast-forward merge:
git checkout main
git merge feature
See the rebase page of Understanding Git Conceptually for a good overview

Somewhere in your code there is a line #include <string>
. This by itself tells you that the program is written in C++. So using g++
is better than gcc
.
For the missing library: you should look around in the file system if you can find a file called libl.so
. Use the locate
command, try /usr/lib
, /usr/local/lib
, /opt/flex/lib
, or use the brute-force find / | grep /libl
.
Once you have found the file, you have to add the directory to the compiler command line, for example:
g++ -o scan lex.yy.c -L/opt/flex/lib -ll
I don't know it's right or not, but it worked for me

According to John Chambers, the operator =
is only allowed at "the top level," which means it is not allowed in control structures like if
, making the following programming error illegal.
> if(x = 0) 1 else x
Error: syntax error
As he writes, "Disallowing the new assignment form [=] in control expressions avoids programming errors (such as the example above) that are more likely with the equal operator than with other S assignments."
You can manage to do this if it's "isolated from surrounding logical structure, by braces or an extra pair of parentheses," so if ((x = 0)) 1 else x
would work.
Check out Open Terminal Here. It may be the most similar to "Open Command Window Here." I used >cdto
and this is very similar but this seems to be a little better at dealing with Spaces... but not perfect.
What it has that is very nice is the ability to "detect key-down events at the start of the application and used them to modify the behavior of the script" allowing the script to open a new tab in the front most terminal window when invoked by holding down ? key. Neat trick.
Also note PCheese's answer; it is probably more useful for heavy terminal users!
It is possible to print what Python lines are executed (thanks Geo!). This has any number of applications, for example, you could modify it to check when particular functions are called or add something like ## make it only track particular lines.
code.interact takes you into a interactive console
import code; code.interact(local=locals())
If you want to be able to easily access your console history look at: "Can I have a history mechanism like in the shell?" (will have to look down for it).
Auto-complete can be enabled for the interpreter.
If the server resides on a remote machine, make sure the file in in the remote machine and not in your local machine.
If the file is in the same machine where the mysql server is, make sure the mysql user has permissions to read/write the file, or copy teh file into the mysql schema directory:
In my case in ubuntu it was: /var/lib/mysql/db_myschema/myfile.csv
Also, not relative to this problem, but if you have problems with the new lines, use sublimeTEXT to change the line endings to WINDOWS format, save the file and retry.
If you're just looking for an actual regex that allows for various dots, underscores and dashes, it as follows: [a-zA-z0-9.-]+\@[a-zA-z0-9.-]+.[a-zA-Z]+
. That will allow a fairly stupid looking email like tom_anderson.1-neo@my-mail_matrix.com
to be validated.
Here's a tricky way to do this - select the cells that you want to replace and in Excel 2010 select F5 to bring up the "goto" box. Hit the "special" button. Select "blanks" - this should select all the cells that are blank. Enter NULL or whatever you want in the formula box and hit ctrl + enter to apply to all selected cells. Easy!

It works as is. To get the output of map use * or list
The difference between them is that they use different pins. Seriously, that's it. The reason they both exist is that RTS/CTS wasn't supposed to ever be a flow control mechanism, originally; it was for half-duplex modems to coordinate who was sending and who was receiving. RTS and CTS got misused for flow control so often that it became standard.
HashMap
is implemented by Hash Table while TreeMap
is implemented by Red-Black tree
. The main difference between HashMap
and TreeMap
actually reflect the main difference between a Hash
and a Binary Tree
, that is, when iterating, TreeMap guarantee can the key order which is determined by either element's compareTo() method or a comparator set in the TreeMap's constructor.
Take a look at following diagram.

Here's an alternative to the accepted answer that works in the current (2.12) version of the API.
<a href="#" onclick="logoutFromFacebookAndRedirect('/logout')">Logout</a>
<script>
FB.init({
appId: '{your-app-id}',
cookie: true,
xfbml: true,
version: 'v2.12'
});
function logoutFromFacebookAndRedirect(redirectUrl) {
FB.getLoginStatus(function (response) {
if (response.status == 'connected')
FB.logout(function (response) {
window.location.href = redirectUrl;
});
else
window.location.href = redirectUrl;
});
}
</script>
var d = $('.text_div');
d.text(d.text().trim().replace(/contains/i, "hello everyone"));
There is a javascript plugin that adds this feature to bootstrap.
When rowlink.js
is included you can do:
<table data-link="row">
<tr><td><a href="foo.html">Foo</a></td><td>This is Foo</td></tr>
<tr><td><a href="bar.html">Bar</a></td><td>Bar is good</td></tr>
</table>
The table will be converted so that the whole row can be clicked instead of only the first column.
Use the link http://ip-api.com/json. This will provide all the information as JSON. From this JSON content you can get the country easily. This site works using your current IP address. It automatically detects the IP address and sendback details.

N.B. - As this is a third-party API, do not use it as the primary solution. And also I am not sure whether it's free or not.
Quote, which summarizes from this article:
- SET is the ANSI standard for variable assignment, SELECT is not.
- SET can only assign one variable at a time, SELECT can make multiple assignments at once.
- If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one)
- When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from its previous value)
- As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.

Pickle is a module installed for both Python 2 and Python 3 by default. See the standard library for 3.6.4 and 2.7.
Also to prove what I am saying is correct try running this script:
import pickle
print(pickle.__doc__)
This will print out the Pickle documentation showing you all the functions (and a bit more) it provides.
Or you can start the integrated Python 3.6 Module Docs and check there.
As a rule of thumb: if you can import the module without an error being produced then it is installed
The reason for the No matching distribution found for pickle
is because libraries for included packages are not available via pip because you already have them (I found this out yesterday when I tried to install an integrated package).
If it's running without errors but it doesn't work as expected I would think that you made a mistake somewhere (perhaps quickly check the functions you are using in the docs). Python is very informative with it's errors so we generally know if something is wrong.
You can generate a stack trace and use the informations in the StackTraceElements.
For example an utility class can return you the calling class name :
public class KDebug {
public static String getCallerClassName() {
StackTraceElement[] stElements = Thread.currentThread().getStackTrace();
for (int i=1; i<stElements.length; i++) {
StackTraceElement ste = stElements[i];
if (!ste.getClassName().equals(KDebug.class.getName()) && ste.getClassName().indexOf("java.lang.Thread")!=0) {
return ste.getClassName();
}
}
return null;
}
}
If you call KDebug.getCallerClassName()
from bar()
, you'll get "foo"
.
Now supposing you want to know the class of the method calling bar
(which is more interesting and maybe what you really wanted). You could use this method :
public static String getCallerCallerClassName() {
StackTraceElement[] stElements = Thread.currentThread().getStackTrace();
String callerClassName = null;
for (int i=1; i<stElements.length; i++) {
StackTraceElement ste = stElements[i];
if (!ste.getClassName().equals(KDebug.class.getName())&& ste.getClassName().indexOf("java.lang.Thread")!=0) {
if (callerClassName==null) {
callerClassName = ste.getClassName();
} else if (!callerClassName.equals(ste.getClassName())) {
return ste.getClassName();
}
}
}
return null;
}
Is that for debugging ? If not, there may be a better solution to your problem.
Thanks to galloglass' answer. The code works great with Python 2.7. There is only one thing I want to metion. When read the manifest.mbdb file, you should use binary mode. Otherwise, not all content are read.

you can also just add it to the command option eg.
command: bash -c "sleep 5; start.sh"
https://github.com/docker/compose/issues/374#issuecomment-156546513
to wait on a port you can also use something like this
command: bash -c "while ! curl -s rabbitmq:5672 > /dev/null; do echo waiting for xxx; sleep 3; done; start.sh"
to increment the waiting time you can hack a bit more:
command: bash -c "for i in {1..100} ; do if ! curl -s rabbitmq:5672 > /dev/null ; then echo waiting on rabbitmq for $i seconds; sleep $i; fi; done; start.sh"
Using the ArrayObject from Std or building your own
(new \ArrayObject($existingStdClass))
you can use the build in method on the new class:
getArrayCopy()
or pass the new object to
iterator_to_array
This link should get you started. Long story short, a div that has been styled to look like a scrollbar is used to catch click-and-drag events. Wired up to these events are methods that scroll the contents of another div which is set to an arbitrary height and typically has a css rule of overflow:scroll (there are variants on the css rules but you get the idea).
I'm all about the learning experience -- but after you've learned how it works, I recommend using a library (of which there are many) to do it. It's one of those "don't reinvent" things...

Some last version of Ubuntu installs Python 3.4 by default and the CMake version from Ubuntu (2.8) only searches up to Python 3.3.

Remember to clean CMakeCache.txt

I found that there is height of div still showing, when it have text or not. So you can use this for best results.
<div style=" overflow:auto;max-height:300px; max-width:300px;"></div>
For those who want to get height and width of device even when the display is resized (dynamically & in real-time):
In that Component do: import { HostListener } from "@angular/core";
In the component's class body write:
@HostListener('window:resize', ['$event'])
onResize(event?) {
this.screenHeight = window.innerHeight;
this.screenWidth = window.innerWidth;
}
In the component's constructor
call the onResize
method to initialize the variables. Also, don't forget to declare them first.
constructor() {
this.onResize();
}
Complete code:
import { Component, OnInit } from "@angular/core";
import { HostListener } from "@angular/core";
@Component({
selector: "app-login",
templateUrl: './login.component.html',
styleUrls: ['./login.component.css']
})
export class FooComponent implements OnInit {
screenHeight: number;
screenWidth: number;
constructor() {
this.getScreenSize();
}
@HostListener('window:resize', ['$event'])
getScreenSize(event?) {
this.screenHeight = window.innerHeight;
this.screenWidth = window.innerWidth;
console.log(this.screenHeight, this.screenWidth);
}
}
I think your question is if having an update_attribute in a before_save will lead to and endless loop (of update_attribute calls in before_save callbacks, originally triggered by an update_attribute call)
I'm pretty sure it does bypass the before_save callback since it doesn't actually save the record. You can also save a record without triggering validations by using
Model.save false
You could default the parameter to null
or false
.
This way, it would be shorter to test if a value has been passed as parameter.
@mixin clearfix($width: null) {
@if not ($width) {
// if width is not passed, or empty do this
} @else {
display: inline-block;
width: $width;
}
}
the very specific answer to the point is confirm dialogue Js Function:
confirm('Do you really want to do so');
It show dialogue box with ok cancel buttons,to replace these button with yes no is not so simple task,for that you need to write jQuery function.
We started finding some machines with IE 11 not playing video (via flash) after we set the emulation mode of our app (web browser control) to 110001. Adding the meta tag to our htm files worked for us.
This depends on a lot of things, such as what is the size of the file, what is its type (text/binary) etc. Some time ago I benchmarked the following function against versions using streambuf iterators - it was about twice as fast:
unsigned int FileRead( std::istream & is, std::vector <char> & buff ) {
is.read( &buff[0], buff.size() );
return is.gcount();
}
void FileRead( std::ifstream & ifs, string & s ) {
const unsigned int BUFSIZE = 64 * 1024; // reasoable sized buffer
std::vector <char> buffer( BUFSIZE );
while( unsigned int n = FileRead( ifs, buffer ) ) {
s.append( &buffer[0], n );
}
}
I observed that for all the answers provided here, the things are not working if we select some portion of the text in textbox and try to overwrite that part. So I modified the function which is as below:
<HTML>
<HEAD>
<SCRIPT language=Javascript>
<!--
function isNumberKey(evt)
{
var charCode = (evt.which) ? evt.which : event.keyCode;
if (charCode != 46 && charCode > 31 && (charCode < 48 || charCode > 57))
{
return false;
}
if (charCode == 46 && evt.srcElement.value.split('.').length>1 )
{
return false;
}
if(evt.srcElement.selectionStart<evt.srcElement.selectionEnd)
{
return true;
}
if(evt.srcElement.value.split('.').length>1 && evt.srcElement.value.split('.')[1].length==2)
{
return false;
}
return true;
}
//-->
</SCRIPT>
</HEAD>
<BODY>
<INPUT id="txtChar" onkeypress="return isNumberKey(event)"
type="text" name="txtChar">

You can use .closest()
to get up to the current <tr>
parent, like this:
$('input[type=button]' ).click(function() {
var bid = this.id; // button ID
var trid = $(this).closest('tr').attr('id'); // table row ID
});
The solution from PSL will not work in Firefox. FF accepts event only as a formal parameter. So you have to find another way to identify the selected row. My solution is something like this:
...
$('#mySelector')
.on('show.bs.modal', function(e) {
var mid;
if (navigator.userAgent.toLowerCase().indexOf('firefox') > -1)
mid = $(e.relatedTarget).data('id');
else
mid = $(event.target).closest('tr').data('id');
...
jQuery is not the same as an array. If you want to append something at the end of a jQuery object, use:
$('#fruit').append(veggies);
or to append it to the end of a form value like in your example:
$('#fruit').val($('#fruit').val()+veggies);
In your case, fruitvegbasket
is a string that contains the current value of #fruit
, not an array.
jQuery (jquery.com) allows for DOM manipulation, and the specific function you called val()
returns the value
attribute of an input
element as a string. You can't push something onto a string.
The problem is twofold:
.
in the routeBy default, IIS treats all URI's with a dot in them as static resource, tries to return it and skip further processing (by Web API) altogether. This is configured in your Web.config in the section system.webServer.handlers
: the default handler handles path="*."
. You won't find much documentation regarding the strange syntax in this path
attribute (regex would have made more sense), but what this apparently means is "anything that doesn't contain a dot" (and any character from point 2 below). Hence the 'Extensionless' in the name ExtensionlessUrlHandler-Integrated-4.0
.
Multiple solutions are possible, in my opinion in the order of 'correctness':
path="*."
attribute to path="*"
. It will then catch everything. Note that from then on, your web api will no longer interpret incoming calls with dots as static resources! If you are hosting static resources on your web api, this is therefor not advised!<system.webserver>
: <modules runAllManagedModulesForAllRequests="true">
:
in the routeAfter you've changed the above, by default, you'd get the following error:
A potentially dangerous Request.Path value was detected from the client (:).
You can change the predefined disallowed/invalid characters in your Web.config. Under <system.web>
, add the following: <httpRuntime requestPathInvalidCharacters="<,>,%,&,*,\,?" />
. I've removed the :
from the standard list of invalid characters.
Although not an answer to your question, a safer and easier solution would be to change the request so that all this is not required. This can be done in two ways:
?date=2012-12-31T22:00:00.000Z
..000
from every request. You'd still need to allow :
's (cfr point 2).The correct answer is n*(n-1)/2. Each edge has been counted twice, hence the division by 2. A complete graph has the maximum number of edges, which is given by n choose 2 = n*(n-1)/2.
So none of the ones listed here worked for me, but using a few of the answers, I got something working:
public string GetBaseUrl()
{
var request = HttpContext.Current.Request;
var appUrl = HttpRuntime.AppDomainAppVirtualPath;
if (appUrl != "/")
appUrl = "/" + appUrl;
var baseUrl = string.Format("{0}://{1}{2}", request.Url.Scheme, request.Url.Authority, appUrl);
return baseUrl;
}
Update for ASP.NET Core / MVC 6:
ASP.NET Core
makes this process a bit more painful, especially if you are deep in your code. You have 2 options to get at the HttpContext
1) Pass it in from your controller
:
var model = new MyClass(HttpContext);
then in model
:
private HttpContext currentContext;
public MyClass(HttpContext currentContext)
{
this.currentContext = currentContext;
}
2) Perhaps the cleaner way is to inject it into your class, which starts with registering the types in your Startup:
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddMvc();
services.AddTransient<MyClass, MyClass>();
services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();
}
then have it injected for you like this:
private HttpContext currentContext;
public MyClass(IHttpContextAccessor httpContextAccessor)
{
currentContext = httpContextAccessor.HttpContext;
}
in either case, here is the updated for .NET Core
GetBaseUrl()
:
public string GetBaseUrl()
{
var request = currentContext.Request;
var host = request.Host.ToUriComponent();
var pathBase = request.PathBase.ToUriComponent();
return $"{request.Scheme}://{host}{pathBase}";
}
If someone is in search for a quick minimal solution,
import signal
# The code which crashes program on interruption
signal.signal(signal.SIGINT, call_this_function_if_interrupted)
# The code skipped if interrupted
Here's an example of a transaction that will rollback on error and return the error code.

$("#chk0") is refering to an element with the id chk0. You might try adding id's to the elements. Ids are unique even though the names are the same so that in jQuery you can access a single element by it's id.
Declaration: "Somewhere, there exists a foo."
Definition: "...and here it is!"
Use the \b
operator (the backspace escape operator) in the second parameter
String test= "Anna Banana";
System.out.println(test); //returns Anna Banana<br><br>
System.out.println(test.replaceAll(" ","\b")); //returns AnnaBanana removing all the spaces in the string
pill ${this.props.styleName}
will get "pill undefined" when you don't set the props
I prefer
className={ "pill " + ( this.props.styleName || "") }
or
className={ "pill " + ( this.props.styleName ? this.props.styleName : "") }

2) Try this: https://github.com/sanathp/DatabaseManager_For_Android
var time = moment().toDate(); // This will return a copy of the Date that the moment uses
time.setHours(0);
time.setMinutes(0);
time.setSeconds(0);
time.setMilliseconds(0);
It is possible to get an SSRS report to appear on an MVC page without using iFrames or an aspx page.
The bulk of the work is explained here:
The link explains how to create a web service and MVC action method that will allow you to call the reporting service and render result of the web service as an Excel file. With a small change to the code in the example you can render it as HTML.
All you need to do then is use a button to call a javascript function that makes an AJAX call to your MVC action which returns the HTML of the report. When the AJAX call returns with the HTML just replace a div with this HTML.
We use AngularJS so my example below is in that format, but it could be any javascript function
$scope.getReport = function()
{
$http({
method: "POST",
url: "Report/ExportReport",
data:
[
{ Name: 'DateFrom', Value: $scope.dateFrom },
{ Name: 'DateTo', Value: $scope.dateTo },
{ Name: 'LocationsCSV', Value: $scope.locationCSV }
]
})
.success(function (serverData)
{
$("#ReportDiv").html(serverData);
});
};
And the Action Method - mainly taken from the above link...
[System.Web.Mvc.HttpPost]
public FileContentResult ExportReport([FromBody]List<ReportParameterModel> parameters)
{
byte[] output;
string extension, mimeType, encoding;
string reportName = "/Reports/DummyReport";
ReportService.Warning[] warnings;
string[] ids;
ReportExporter.Export(
"ReportExecutionServiceSoap"
new NetworkCredential("username", "password", "domain"),
reportName,
parameters.ToArray(),
ExportFormat.HTML4,
out output,
out extension,
out mimeType,
out encoding,
out warnings,
out ids
);
//-------------------------------------------------------------
// Set HTTP Response Header to show download dialog popup
//-------------------------------------------------------------
Response.AddHeader("content-disposition", string.Format("attachment;filename=GeneratedExcelFile{0:yyyyMMdd}.{1}", DateTime.Today, extension));
return new FileContentResult(output, mimeType);
}
So the result is that you get to pass parameters to an SSRS reporting server which returns a report which you render as HTML. Everything appears on the one page. This is the best solution I could find
My understanding is that "-u" or "--set-upstream" allows you to specify the upstream (remote) repository for the branch you're on, so that next time you run "git push", you don't even have to specify the remote repository.
Push and set upstream (remote) repository as origin:
$ git push -u origin
Next time you push, you don't have to specify the remote repository:
$ git push
If you want to do it without a plugin you could use the following.
Javascript, using jQuery:
$(document).ready( function (){
$("#your_form").submit( function(submitEvent) {
// get the file name, possibly with path (depends on browser)
var filename = $("#file_input").val();
// Use a regular expression to trim everything before final dot
var extension = filename.replace(/^.*\./, '');
// Iff there is no dot anywhere in filename, we would have extension == filename,
// so we account for this possibility now
if (extension == filename) {
extension = '';
} else {
// if there is an extension, we convert to lower case
// (N.B. this conversion will not effect the value of the extension
// on the file upload.)
extension = extension.toLowerCase();
}
switch (extension) {
case 'jpg':
case 'jpeg':
case 'png':
alert("it's got an extension which suggests it's a PNG or JPG image (but N.B. that's only its name, so let's be sure that we, say, check the mime-type server-side!)");
// uncomment the next line to allow the form to submitted in this case:
// break;
default:
// Cancel the form submission
submitEvent.preventDefault();
}
});
});
HTML:
<form id="your_form" method="post" enctype="multipart/form-data">
<input id="file_input" type="file" />
<input type="submit">
</form>
I've done this with a T4 template. It is fairly trivial to drop a .tt file into your project, and set up Visual Studio to run the T4 template as a pre-build step.
The T4 generates a .cs file, which means you can have it just query the database and build an enum in a .cs file from the result. Wired up as a pre-build task, it would re-create your enum on every build, or you can run the T4 manually as needed instead.
I recommend IdentityServer.This is a .NET Foundation project and covers many issues about authentication and authorization.
IdentityServer is a .NET/Katana-based framework and hostable component that allows implementing single sign-on and access control for modern web applications and APIs using protocols like OpenID Connect and OAuth2. It supports a wide range of clients like mobile, web, SPAs and desktop applications and is extensible to allow integration in new and existing architectures.
check out the documentation and the demo.
The Android Documentation says the following about Log Levels:
Verbose should never be compiled into an application except during development. Debug logs are compiled in but stripped at runtime. Error, warning and info logs are always kept.
So you may want to consider stripping the log Verbose logging statements out, possibly using ProGuard as suggested in another answer.
According to the documentation, you can configure logging on a development device using System Properties. The property to set is log.tag.<YourTag>
and it should be set to one of the following values: VERBOSE
, DEBUG
, INFO
, WARN
, ERROR
, ASSERT
, or SUPPRESS
. More information on this is available in the documentation for the isLoggable()
method.
You can set properties temporarily using the setprop
command. For example:
C:\android>adb shell setprop log.tag.MyAppTag WARN
C:\android>adb shell getprop log.tag.MyAppTag
WARN
Alternatively, you can specify them in the file '/data/local.prop' as follows:
log.tag.MyAppTag=WARN
Later versions of Android appear to require that /data/local.prop be read only. This file is read at boot time so you'll need to restart after updating it. If /data/local.prop
is world writable, it will likely be ignored.
Finally, you can set them programmatically using the System.setProperty()
method.
I was just searching for a solution for this :)
it appears that you can't have OkControlID assign to a control if you want to that control fires an event, just removing this property I got everything working again.
my code (working):
<asp:Panel ID="pnlResetPanelsView" CssClass="modalPopup" runat="server" Style="display:none;">
<h2>
Warning</h2>
<p>
Do you really want to reset the panels to the default view?</p>
<div style="text-align: center;">
<asp:Button ID="btnResetPanelsViewOK" Width="60" runat="server" Text="Yes"
CssClass="buttonSuperOfficeLayout" OnClick="btnResetPanelsViewOK_Click" />
<asp:Button ID="btnResetPanelsViewCancel" Width="60" runat="server" Text="No" CssClass="buttonSuperOfficeLayout" />
</div>
</asp:Panel>
<ajax:ModalPopupExtender ID="mpeResetPanelsView" runat="server" TargetControlID="btnResetView"
PopupControlID="pnlResetPanelsView" BackgroundCssClass="modalBackground" DropShadow="true"
CancelControlID="btnResetPanelsViewCancel" />
Simply get last month.
Today is: 2020-09-02
Code:
echo date('Y-m-d', strtotime(date('Y-m-d')." -1 month"));
Result:
2020-08-02
As the error message says, non-default argument til
should not follow default argument hgt
.
Changing order of parameters (function call also be adjusted accordingly) or making hgt
non-default parameter will solve your problem.
def a(len1, hgt=len1, til, col=0):
->
def a(len1, hgt, til, col=0):
UPDATE
Another issue that is hidden by the SyntaxError.
os.system
accepts only one string parameter.
def a(len1, hgt, til, col=0):
system('mode con cols=%s lines=%s' % (len1, hgt))
system('title %s' % til)
system('color %s' % col)
Alternative:
boolean isWhiteSpaces( String s ) {
return s != null && s.matches("\\s+");
}
Instead of using the new pragmas, you can also use __attribute__((optimize("O0")))
for your needs. This has the advantage of just applying to a single function and not all functions defined in the same file.
Usage example:
void __attribute__((optimize("O0"))) foo(unsigned char data) {
// unmodifiable compiler code
}
