Re the solution for SqlBulkCopy:
I used the StreamReader to convert and process the text file. The result was a list of my object.
I created a class than takes Datatable
or a List<T>
and a Buffer size (CommitBatchSize
). It will convert the list to a data table using an extension (in the second class).
It works very fast. On my PC, I am able to insert more than 10 million complicated records in less than 10 seconds.
Here is the class:
using System;
using System.Collections;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Data.SqlClient;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace DAL
{
public class BulkUploadToSql<T>
{
public IList<T> InternalStore { get; set; }
public string TableName { get; set; }
public int CommitBatchSize { get; set; }=1000;
public string ConnectionString { get; set; }
public void Commit()
{
if (InternalStore.Count>0)
{
DataTable dt;
int numberOfPages = (InternalStore.Count / CommitBatchSize) + (InternalStore.Count % CommitBatchSize == 0 ? 0 : 1);
for (int pageIndex = 0; pageIndex < numberOfPages; pageIndex++)
{
dt= InternalStore.Skip(pageIndex * CommitBatchSize).Take(CommitBatchSize).ToDataTable();
BulkInsert(dt);
}
}
}
public void BulkInsert(DataTable dt)
{
using (SqlConnection connection = new SqlConnection(ConnectionString))
{
// make sure to enable triggers
// more on triggers in next post
SqlBulkCopy bulkCopy =
new SqlBulkCopy
(
connection,
SqlBulkCopyOptions.TableLock |
SqlBulkCopyOptions.FireTriggers |
SqlBulkCopyOptions.UseInternalTransaction,
null
);
// set the destination table name
bulkCopy.DestinationTableName = TableName;
connection.Open();
// write the data in the "dataTable"
bulkCopy.WriteToServer(dt);
connection.Close();
}
// reset
//this.dataTable.Clear();
}
}
public static class BulkUploadToSqlHelper
{
public static DataTable ToDataTable<T>(this IEnumerable<T> data)
{
PropertyDescriptorCollection properties =
TypeDescriptor.GetProperties(typeof(T));
DataTable table = new DataTable();
foreach (PropertyDescriptor prop in properties)
table.Columns.Add(prop.Name, Nullable.GetUnderlyingType(prop.PropertyType) ?? prop.PropertyType);
foreach (T item in data)
{
DataRow row = table.NewRow();
foreach (PropertyDescriptor prop in properties)
row[prop.Name] = prop.GetValue(item) ?? DBNull.Value;
table.Rows.Add(row);
}
return table;
}
}
}
Here is an example when I want to insert a List of my custom object List<PuckDetection>
(ListDetections
):
var objBulk = new BulkUploadToSql<PuckDetection>()
{
InternalStore = ListDetections,
TableName= "PuckDetections",
CommitBatchSize=1000,
ConnectionString="ENTER YOU CONNECTION STRING"
};
objBulk.Commit();
The BulkInsert
class can be modified to add column mapping if required. Example you have an Identity key as first column.(this assuming that the column names in the datatable are the same as the database)
//ADD COLUMN MAPPING
foreach (DataColumn col in dt.Columns)
{
bulkCopy.ColumnMappings.Add(col.ColumnName, col.ColumnName);
}
You need to change your Ajax call to
$.ajax({
type: "POST",
url: "/people",
data: '[{ "name": "John", "location": "Boston" }, { "name": "Dave", "location": "Lancaster" }]',
contentType: "json",
processData: false,
success:function(data) {
$('#save_message').html(data.message);
}
});
change the dataType
to contentType
and add the processData
option.
To retrieve the JSON payload from your controller, use:
dd(json_decode($request->getContent(), true));
instead of
dd($request->all());

>>> a = 255556
>>> a == 255556
True
>>> a is 255556
False
I think that should answer it ;-)
The reason is that some often-used objects, such as the booleans True and False, all 1-letter strings and short numbers are allocated once by the interpreter, and each variable containing that object refers to it. Other numbers and larger strings are allocated on demand. The 255556 for instance is allocated three times, every time a different object is created. And therefore, according to is
, they are not the same.
First the mysqldump command is executed and the output generated is redirected using the pipe. The pipe is sending the standard output into the gzip command as standard input. Following the filename.gz, is the output redirection operator (>) which is going to continue redirecting the data until the last filename, which is where the data will be saved.
For example, this command will dump the database and run it through gzip and the data will finally land in three.gz
mysqldump -u user -pupasswd my-database | gzip > one.gz > two.gz > three.gz
$> ls -l
-rw-r--r-- 1 uname grp 0 Mar 9 00:37 one.gz
-rw-r--r-- 1 uname grp 1246 Mar 9 00:37 three.gz
-rw-r--r-- 1 uname grp 0 Mar 9 00:37 two.gz
My original answer is an example of redirecting the database dump to many compressed files (without double compressing). (Since I scanned the question and seriously missed - sorry about that)
This is an example of recompressing files:
mysqldump -u user -pupasswd my-database | gzip -c > one.gz; gzip -c one.gz > two.gz; gzip -c two.gz > three.gz
$> ls -l
-rw-r--r-- 1 uname grp 1246 Mar 9 00:44 one.gz
-rw-r--r-- 1 uname grp 1306 Mar 9 00:44 three.gz
-rw-r--r-- 1 uname grp 1276 Mar 9 00:44 two.gz
This is a good resource explaining I/O redirection: http://www.codecoffee.com/tipsforlinux/articles2/042.html
If you'd like, you could use require. This is a way to have a conditional require statement.
let something = null;
let other = null;
if (condition) {
something = require('something');
other = require('something').other;
}
if (something && other) {
something.doStuff();
other.doOtherStuff();
}
Another but much more elegant solution for this is as follows:
/**
* Convert number secs to display time
*
* 65 input becomes 01:05.
*
* @param Number inputSeconds Seconds input.
*/
export const toMMSS = inputSeconds => {
const secs = parseInt( inputSeconds, 10 );
let minutes = Math.floor( secs / 60 );
let seconds = secs - minutes * 60;
if ( 10 > minutes ) {
minutes = '0' + minutes;
}
if ( 10 > seconds ) {
seconds = '0' + seconds;
}
// Return display.
return minutes + ':' + seconds;
};
This cross-browser lib seems safer - just zoom and moz-transform won't cover as many browsers as jquery.transform2d's scale().
http://louisremi.github.io/jquery.transform.js/
For example
$('#div').css({ transform: 'scale(.5)' });
OK - I see people are voting this down without an explanation. The other answer here won't work in old Safari (people running Tiger), and it won't work consistently in some older browsers - that is, it does scale things but it does so in a way that's either very pixellated or shifts the position of the element in a way that doesn't match other browsers.

Or just look at this question, which this one is likely just a dupe of:
In list comprehension the loop variable i becomes global. After the iteration in the for loop it is a reference to the last element in your list.
If you want all matches then assign the list to a variable:
filtered = [ i for i in my_list if i=='two']
If you want only the first match you could use a function generator
try:
m = next( i for i in my_list if i=='two' )
except StopIteration:
m = None
var ids = [];
$('input[id="find-table"]:checked').each(function() {
ids.push(this.value);
});
This one worked for me!
I had the same problem, with which I struggled for few days, reading all the blog posts, watching videos and finally after i changed my uno board, it worked perfectly well. But before I did that, there were a few things I tried, which I think also had an effect.
Hope this answer helps you.
When it says users are connected, what does the query "select * from pg_stat_activity;" say? Are the other users besides yourself now connected? If so, you might have to edit your pg_hba.conf file to reject connections from other users, or shut down whatever app is accessing the pg database to be able to drop it. I have this problem on occasion in production. Set pg_hba.conf to have a two lines like this:
local all all ident
host all all 127.0.0.1/32 reject
and tell pgsql to reload or restart (i.e. either sudo /etc/init.d/postgresql reload or pg_ctl reload) and now the only way to connect to your machine is via local sockets. I'm assuming you're on linux. If not this may need to be tweaked to something other than local / ident on that first line, to something like host ... yourusername.
Now you should be able to do:
psql postgres
drop database mydatabase;
Well, my solution uses residue technique. We can place the values under sorting in the upper 2 bytes and the indices of the elements - in the lower 2 bytes:
int myints[] = {32,71,12,45,26,80,53,33};
for (int i = 0; i < 8; i++)
myints[i] = myints[i]*(1 << 16) + i;
Then sort the array myints
as usual:
std::vector<int> myvector(myints, myints+8);
sort(myvector.begin(), myvector.begin()+8, std::less<int>());
After that you can access the elements' indices via residuum. The following code prints the indices of the values sorted in the ascending order:
for (std::vector<int>::iterator it = myvector.begin(); it != myvector.end(); ++it)
std::cout << ' ' << (*it)%(1 << 16);
Of course, this technique works only for the relatively small values in the original array myints
(i.e. those which can fit into upper 2 bytes of int
). But it has additional benefit of distinguishing identical values of myints
: their indices will be printed in the right order.
Arrays must have zero based integer indexes in JavaScript. So:
var valueToPush = new Array();
valueToPush[0] = productID;
valueToPush[1] = itemColorTitle;
valueToPush[2] = itemColorPath;
cookie_value_add.push(valueToPush);
Or maybe you want to use objects (which are associative arrays):
var valueToPush = { }; // or "var valueToPush = new Object();" which is the same
valueToPush["productID"] = productID;
valueToPush["itemColorTitle"] = itemColorTitle;
valueToPush["itemColorPath"] = itemColorPath;
cookie_value_add.push(valueToPush);
which is equivalent to:
var valueToPush = { };
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;
cookie_value_add.push(valueToPush);
It's a really fundamental and crucial difference between JavaScript arrays and JavaScript objects (which are associative arrays) that every JavaScript developer must understand.
You can create a non-nullable DATETIME column on your table, and create a DEFAULT constraint on it to auto populate when a row is added.
e.g.
CREATE TABLE Example
(
SomeField INTEGER,
DateCreated DATETIME NOT NULL DEFAULT(GETDATE())
)
If you use :active selector in combination with :hover you can achieve this according to w3schools as long as the :active selector is called after the :hover selector.
.info-slide:hover, .info-slide:active{
height:300px;
}
You'd have to test the FIDDLE in a mobile environment. I can't at the moment.

Go to Hbase home directory and run this command,
./bin/hbase org.apache.hadoop.hbase.mapreduce.RowCounter 'namespace:tablename'
This will launch a mapreduce job and the output will show the number of records existing in the hbase table.

It does depend on the HTTP headers sent with the CSS files as both of the previous answers state - as long as you don't append any cachebusting stuff to the href. e.g.
<link href="/stylesheets/mycss.css?some_var_to_bust_cache=24312345" rel="stylesheet" type="text/css" />
Some frameworks (e.g. rails) put these in by default.
However If you get something like firebug or fiddler, you can see exactly what your browser is downloading on each request - which is expecially useful for finding out what your browser is doing, as opposed to just what it should be doing.
All browsers should respect the cache headers in the same way, unless configured to ignore them (but there are bound to be exceptions)
Add a Console.ReadKey

How can i run a jar file in command prompt but with arguments
.
To pass arguments to the jar file at the time of execution
java -jar myjar.jar arg1 arg2
In the main() method of "Main-Class" [mentioned in the manifest.mft file]of your JAR file. you can retrieve them like this:
String arg1 = args[0];
String arg2 = args[1];

Toast.makeText(getApplicationContext(), "received", Toast.LENGTH_SHORT);
makes the toast, but doesnt show it.
You have to do Toast.makeText(getApplicationContext(), "received", Toast.LENGTH_SHORT).show();
If i
is the int
, then
char c = i;
makes it a char
. You might want to add a check that the value is <128
if it comes from an untrusted source. This is best done with isascii

, if available on your system (see @Steve Jessop's comment to this answer).

Per the developers, this error is not an actual failure, but rather "misleading error reports". This bug is fixed in version 40, which is available on the canary and dev channels as of 25 Oct.
You can simply add DISTINCT in front.
SELECT GROUP_CONCAT(DISTINCT categories SEPARATOR ' ')
if you want to sort,
SELECT GROUP_CONCAT(DISTINCT categories ORDER BY categories ASC SEPARATOR ' ')
I think you are looking for UPDATE and not insert?
UPDATE `users`

The example for switch statement shows that you can't stack non-empty case
s, but should use goto
s:
// statements_switch.cs
using System;
class SwitchTest
{
public static void Main()
{
Console.WriteLine("Coffee sizes: 1=Small 2=Medium 3=Large");
Console.Write("Please enter your selection: ");
string s = Console.ReadLine();
int n = int.Parse(s);
int cost = 0;
switch(n)
{
case 1:
cost += 25;
break;
case 2:
cost += 25;
goto case 1;
case 3:
cost += 50;
goto case 1;
default:
Console.WriteLine("Invalid selection. Please select 1, 2, or3.");
break;
}
if (cost != 0)
Console.WriteLine("Please insert {0} cents.", cost);
Console.WriteLine("Thank you for your business.");
}
}
Use checked="checked"
attribute if you want your checkbox to be checked.
I wrote with parameters that are predefined
They are not "predefined" logically, somewhere inside your code. But as arguments of SP they have no default values and are required. To avoid passing those params explicitly you have to define default values in SP definition:
Alter Procedure [Test]
@StartDate AS varchar(6) = NULL,
@EndDate AS varchar(6) = NULL
AS
...
NULLs or empty strings or something more sensible - up to you. It does not matter since you are overwriting values of those arguments in the first lines of SP.
Now you can call it without passing any arguments e.g.
exec dbo.TEST
Installing version 1.1.8 of enum34 worked for me.
I was able to fix this by adding enum34 = "==1.1.8" to pyproject.toml. Apparently enum34 had a feature in v1.1.8 that avoided this error, but this regressed in v1.1.9+. This is just a workaround though. The better solution would be for packages to use environment markers so you don't have to install enum34 at all unless needed.
With android
command something as below,
$ /usr/local/android-studio/sdk/tools/android
We can specify how we have to join the string. Instead of '-', we can use ' '

Since Bootstrap 3 removed the submenu part and we need to adapt ourselves the style, I think it's better to go with SmartMenu Bootstrap: https://vadikom.github.io/smartmenus/src/demo/bootstrap-navbar.html#
That would save us time on mobile responsive and style.
This plugin also very promising.
And if you want to run a second function after the first one finishes, see this stackoverflow answer.
Express makes this kind of stuff really intuitive. The syntax looks like below :
var app = require('express').createServer();
app.get("/string", function(req, res) {
var strings = ["rad", "bla", "ska"]
var n = Math.floor(Math.random() * strings.length)
res.send(strings[n])
})
app.listen(8001)
If you're using jQuery on the client side you can do something like this:
$.get("/string", function(string) {
alert(string)
})

If you are looking for a way to "mount" files, like -v
for docker run
, you can now use the --secret
flag for docker build
echo 'WARMACHINEROX' > mysecret.txt
docker build --secret id=mysecret,src=mysecret.txt .
And inside your Dockerfile you can now access this secret
# syntax = docker/dockerfile:1.0-experimental
FROM alpine
# shows secret from default secret location:
RUN --mount=type=secret,id=mysecret cat /run/secrets/mysecret
# shows secret from custom secret location:
RUN --mount=type=secret,id=mysecret,dst=/foobar cat /foobar
More in-depth information about --secret available on Docker Docs
I determined that this problem was a corrupt connection manager by identifying the specific connection that was failing. I'm working in SQL Server 2016 and I have created the SSISDB catalog and I am deploying my projects there.
Here's the short answer. Delete the connection manager and then re-create it with the same name. Make sure the packages using that connection are still wired up correctly and you should be good to go. If you're not sure how to do that, I've included the detailed procedure below.
To identify the corrupt connection, I did the following. In SSMS, I opened the Integration Services Catalogs folder, then the SSISDB folder, then the folder for my solution, and on down until I found my list of packages for that project.
By right clicking the package that failed, going to reports>standard reports>all executions, selecting the last execution, and viewing the "All Messages" report I was able to isolate which connection was failing. In my case, the connection manager to my destination. I simply deleted the connection manager and then recreated a new connection manager with the same name.
Subsequently, I went into my package, opened the data flow, found that some of my destinations had lit up with the red X. I opened the destination, re-selected the correct connection name, re-selected the target table, and checked the mappings were still correct. I had six destinations and only three had the red X but I clicked all of them and made sure they were still configured correctly.
In my case this was because a file named ociw32.dll had been placed in c:\windows\system32. This is however only allowed to exist in c:\oracle\11.2.0.3\bin.
Deleting the file from system32, which had been placed there by an installation of Crystal Reports, fixed this issue

and lines
to add the separate series.) To use plot
multiple times with par(new=TRUE)
you need to make sure that your first plot has a proper ylim
to accept the all series (and in another situation, you may need to also use the same strategy for xlim):
# first plot
plot(x, y1, ylim=range(c(y1,y2)))
# second plot EDIT: needs to have same ylim
par(new = TRUE)
plot(x, y2, ylim=range(c(y1,y2)), axes = FALSE, xlab = "", ylab = "")
This next code will do the task more compactly, by default you get numbers as points but the second one gives you typical R-type-"points":
matplot(x, cbind(y1,y2))
matplot(x, cbind(y1,y2), pch=1)
I'm not saying that Array
-> |value,index|
and Hash
-> |key,value|
is not insane (see Horace Loeb's comment), but I am saying that there is a sane way to expect this arrangement.
When I am dealing with arrays, I am focused on the elements in the array (not the index because the index is transitory). The method is each with index, i.e. each+index, or |each,index|, or |value,index|
. This is also consistent with the index being viewed as an optional argument, e.g. |value| is equivalent to |value,index=nil| which is consistent with |value,index|.
When I am dealing with hashes, I am often more focused on the keys than the values, and I am usually dealing with keys and values in that order, either key => value
or hash[key] = value
.
If you want duck-typing, then either explicitly use a defined method as Brent Longborough showed, or an implicit method as maxhawkins showed.
Ruby is all about accommodating the language to suit the programmer, not about the programmer accommodating to suit the language. This is why there are so many ways. There are so many ways to think about something. In Ruby, you choose the closest and the rest of the code usually falls out extremely neatly and concisely.
As for the original question, "What is the “right” way to iterate through an array in Ruby?", well, I think the core way (i.e. without powerful syntactic sugar or object oriented power) is to do:
for index in 0 ... array.size
puts "array[#{index}] = #{array[index].inspect}"
end
But Ruby is all about powerful syntactic sugar and object oriented power, but anyway here is the equivalent for hashes, and the keys can be ordered or not:
for key in hash.keys.sort
puts "hash[#{key.inspect}] = #{hash[key].inspect}"
end
So, my answer is, "The “right” way to iterate through an array in Ruby depends on you (i.e. the programmer or the programming team) and the project.". The better Ruby programmer makes the better choice (of which syntactic power and/or which object oriented approach). The better Ruby programmer continues to look for more ways.
Now, I want to ask another question, "What is the “right” way to iterate through a Range in Ruby backwards?"! (This question is how I came to this page.)
It is nice to do (for the forwards):
(1..10).each{|i| puts "i=#{i}" }
but I don't like to do (for the backwards):
(1..10).to_a.reverse.each{|i| puts "i=#{i}" }
Well, I don't actually mind doing that too much, but when I am teaching going backwards, I want to show my students a nice symmetry (i.e. with minimal difference, e.g. only adding a reverse, or a step -1, but without modifying anything else). You can do (for symmetry):
(a=*1..10).each{|i| puts "i=#{i}" }
and
(a=*1..10).reverse.each{|i| puts "i=#{i}" }
which I don't like much, but you can't do
(*1..10).each{|i| puts "i=#{i}" }
(*1..10).reverse.each{|i| puts "i=#{i}" }
#
(1..10).step(1){|i| puts "i=#{i}" }
(1..10).step(-1){|i| puts "i=#{i}" }
#
(1..10).each{|i| puts "i=#{i}" }
(10..1).each{|i| puts "i=#{i}" } # I don't want this though. It's dangerous
You could ultimately do
class Range
def each_reverse(&block)
self.to_a.reverse.each(&block)
end
end
but I want to teach pure Ruby rather than object oriented approaches (just yet). I would like to iterate backwards:
I believe this is impossible without defining a pred
method, which means modifying the Range class to use it. If you can do this please let me know, otherwise confirmation of impossibility would be appreciated though it would be disappointing. Perhaps Ruby 1.9 addresses this.
(Thanks for your time in reading this.)
See this post to find difference between range and xrange:
To quote:
range
returns exactly what you think: a list of consecutive integers, of a defined length beginning with 0.xrange
, however, returns an "xrange object", which acts a great deal like an iterator
Here is how one can do it. I will give an example with joining so that it becomes super clear to someone.
$products = DB::table('products AS pr')
->leftJoin('product_families AS pf', 'pf.id', '=', 'pr.product_family_id')
->select('pr.id as id', 'pf.name as product_family_name', 'pf.id as product_family_id')
->orderBy('pr.id', 'desc')
->get();
Hope this helps.
version 4.7.1 was slightly different : for import:
import org.antlr.v4.runtime.*;
for the main segment - note the CharStreams:
CharStream in = CharStreams.fromString("12*(5-6)");
ExpLexer lexer = new ExpLexer(in);
CommonTokenStream tokens = new CommonTokenStream(lexer);
ExpParser parser = new ExpParser(tokens);
You can pass "<>"
(including the quotes) as the parameter for criteria
. This basically says, as long as its not empty/blank, count it. I believe this is what you want.
=COUNTIF(A1:A10, "<>")
Otherwise you can use CountA
as Scott suggests
If you have a solution which contains for example Web Application and Test Project, you probably want that Test Project uses Web Application's web.config.
One way to solve it is to copy web.config to test project and rename it as app.config.
Another and better solution is to modify build chain and make it to make automatic copy of web.config to test projects output directory. To do that, right click Test Application and select properties. Now you should see project properties. Click "Build Events" and then click "Edit Post-build..." button. Write following line to there:
copy "$(SolutionDir)\WebApplication1\web.config" "$(ProjectDir)$(OutDir)$(TargetFileName).config"
And click OK. (Note you most probably need to change WebApplication1 as you project name which you want to test). If you have wrong path to web.config then copy fails and you will notice it during unsuccessful build.
Edit:
To Copy from the current Project to the Test Project:
copy "$(ProjectDir)bin\WebProject.dll.config" "$(SolutionDir)WebProject.Tests\bin\Debug\App.Config"
If you want to drop rows of data frame on the basis of some complicated condition on the column value then writing that in the way shown above can be complicated. I have the following simpler solution which always works. Let us assume that you want to drop the column with 'header' so get that column in a list first.
text_data = df['name'].tolist()
now apply some function on the every element of the list and put that in a panda series:
text_length = pd.Series([func(t) for t in text_data])
in my case I was just trying to get the number of tokens:
text_length = pd.Series([len(t.split()) for t in text_data])
now add one extra column with the above series in the data frame:
df = df.assign(text_length = text_length .values)
now we can apply condition on the new column such as:
df = df[df.text_length > 10]
def pass_filter(df, label, length, pass_type):
text_data = df[label].tolist()
text_length = pd.Series([len(t.split()) for t in text_data])
df = df.assign(text_length = text_length .values)
if pass_type == 'high':
df = df[df.text_length > length]
if pass_type == 'low':
df = df[df.text_length < length]
df = df.drop(columns=['text_length'])
return df
Following is a simple function to check if a particular node is present or not in the xml file.

doc.getDocumentElement().normalize();
if(doc.getElementsByTagName(paramName).getLength()>0)

Use this to validate google captcha with simple javascript.
This code at the html body:
<div class="g-recaptcha" id="rcaptcha" style="margin-left: 90px;" data-sitekey="my_key"></div>
<span id="captcha" style="margin-left:100px;color:red" />
This code put at head section on call get_action(this) method form button:
function get_action(form)
{
var v = grecaptcha.getResponse();
if(v.length == 0)
{
document.getElementById('captcha').innerHTML="You can't leave Captcha Code empty";
return false;
}
else
{
document.getElementById('captcha').innerHTML="Captcha completed";
return true;
}
}
Use toString() when you want to present information to a user (including a developer looking at a log). Never rely in your code on toString()
giving a specific value. Never test it against a specific string. If your code breaks when someone correctly changes the toString()
return, then it was already broken.
If you need to get the exact name used to declare the enum constant, you should use name() as toString
may have been overridden.
First include the header corresponding to the .cpp... in other words, source1.cpp
should include source1.h
before including anything else. The only exception I can think of is when using MSVC with pre-compiled headers in which case, you are forced to include stdafx.h
before anything else.
Reasoning: Including the source1.h
before any other files ensures that it can stand alone without it's dependencies. If source1.h
takes on a dependency on a later date, the compiler will immediately alert you to add the required forward declarations to source1.h
. This in turn ensures that headers can be included in any order by their dependants.
Example:
source1.h
class Class1 {
Class2 c2; // a dependency which has not been forward declared
};
source1.cpp
#include "source1.h" // now compiler will alert you saying that Class2 is undefined
// so you can forward declare Class2 within source1.h
...
MSVC users: I strongly recommend using pre-compiled headers. So, move all #include
directives for standard headers (and other headers which are never going to change) to stdafx.h
.
Here you go, create a .bat file with the following in it :
@echo off
REM Creating a Newline variable (the two blank lines are required!)
set NLM=^
set NL=^^^%NLM%%NLM%^%NLM%%NLM%
REM Example Usage:
echo There should be a newline%NL%inserted here.
echo.
pause
You should see output like the following:
There should be a newline
inserted here.
Press any key to continue . . .
You only need the code between the REM statements, obviously.
This solution works like a charm (updated in 2017 to honor that log_format needs to be in the http part of the nginx config):
log_format postdata $request_body;
server {
# (...)
location = /post.php {
access_log /var/log/nginx/postdata.log postdata;
fastcgi_pass php_cgi;
}
}
I think the trick is making nginx believe that you will call a cgi script.
If you want the country domain name - for example to extract .com from stackoverflow.com :
(ES6):
const getCountryDomainName = () => {
let hostName = window.location.hostname;
let lastDotIndex = hostName.lastIndexOf('.');
let countryDomainName = hostName.substr(lastDotIndex+1, hostName.length);
return countryDomainName;
}
(ES5):
function getCountryDomainName() {
let hostName = window.location.hostname;
let lastDotIndex = hostName.lastIndexOf('.');
let countryDomainName = hostName.substr(lastDotIndex+1, hostName.length);
return countryDomainName;
}
Then, just use the function to assign the value to a var:
const countryDomainName = getCountryDomainName();
You can use Apache Subversion. It is owner of subversion . You can download from here . After install it, you have to restart pc to use svn from command line.
I would do like this:
String title_part = "title part1.txt";
int i;
for(i=title_part.length()-1 ; i>=0 && title_part.charAt(i)!='.' ; i--);
title_part = title_part.substring(0,i);
Starting to the end till the '.' then call substring.
Edit: Might not be a golf but it's effective :)
If you are working with maven project, then add following dependency to your pom.xml

Since your compiler probably doesn't support all of C++11 yet, which supports similar syntax, you're getting these errors because you have to initialize your class members in constructors:

Live @Sergey's solution but with integer division.
double value = 23.8764367843;
double rounded = (double) Math.round(value * 100) / 100;
System.out.println(value +" rounded is "+ rounded);
prints
23.8764367843 rounded is 23.88
EDIT: As Sergey points out, there should be no difference between multipling double*int and double*double and dividing double/int and double/double. I can't find an example where the result is different. However on x86/x64 and other systems there is a specific machine code instruction for mixed double,int values which I believe the JVM uses.
for (int j = 0; j < 11; j++) {

}
long time = System.nanoTime() - start;
System.out.printf("double,int operations %,d%n", time);
}
for (int j = 0; j < 11; j++) {
long start = System.nanoTime();
for (double i = 1; i < 1e6; i *= 1.0000001) {
double rounded = (double) Math.round(i * 100.0) / 100.0;

So, your input is 'dan|warrior|54' and you want "warrior". You do this like so:
>>> dan = 'dan|warrior|54'
>>> dan.split('|')[1]
"warrior"

findAny
Optional<T> findAny()
Returns an Optional describing some element of the stream, or an empty Optional if the stream is empty. This is a short-circuiting terminal operation. The behavior of this operation is explicitly nondeterministic; it is free to select any element in the stream. This is to allow for maximal performance in parallel operations; the cost is that multiple invocations on the same source may not return the same result. (If a stable result is desired, use findFirst() instead.)
The reason for your fatal error is DOMDocument does not have a __toString() method and thus can not be echo'ed.

More generally, the following syntax will always tell you which files changed between two commits (specified by their SHAs or other names):
git diff --name-only <commit1> <commit2>
I see a lot of complicated answers, while this is super simple in Bootstrap 3:
Step 1: Use the official example code to create your radio button group, and give the container an id:
<div id="myButtons" class="btn-group" data-toggle="buttons">
<label class="btn btn-primary active">
<input type="radio" name="options" id="option1" autocomplete="off" checked> Radio 1 (preselected)
</label>
<label class="btn btn-primary">
<input type="radio" name="options" id="option2" autocomplete="off"> Radio 2
</label>
<label class="btn btn-primary">
<input type="radio" name="options" id="option3" autocomplete="off"> Radio 3
</label>
</div>
Step 2: Use this jQuery handler:
$("#myButtons :input").change(function() {
console.log(this); // points to the clicked input button
});

The modern approach in 2019 is using ES6 module type scripts.
<script type="module" src="..."></script>
By default, modules are loaded asynchronously and defered. i.e. you can place them anywhere and they will load in parallel and execute when the page finishes loading.
The differences between a script and a module are described here:
https://stackoverflow.com/a/53821485/731548
The execution of a module compared to a script is described here:

The d3
print below is the one you are looking for (which is the combination of dumps and loads) :)
Having:
import json
d = """{"Aa": 1, "BB": "blabla", "cc": "False"}"""
d1 = json.loads(d) # Produces a dictionary out of the given string
d2 = json.dumps(d) # Produces a string out of a given dict or string
d3 = json.dumps(json.loads(d)) # 'dumps' gets the dict from 'loads' this time
print "d1: " + str(d1)
print "d2: " + d2
print "d3: " + d3
Prints:
d1: {u'Aa': 1, u'cc': u'False', u'BB': u'blabla'}
d2: "{\"Aa\": 1, \"BB\": \"blabla\", \"cc\": \"False\"}"
d3: {"Aa": 1, "cc": "False", "BB": "blabla"}
As long as the value of width is auto, the element can have horizontal margin, padding and border without becoming wider than its container (unless of course the sum of margin-left + border-left-width + padding-left + padding-right + border-right-width + margin-right is larger than the container). The width of its content box will be whatever is left when the margin, padding and border have been subtracted from the container’s width.
On the other hand, if you specify width:100%, the element’s total width will be 100% of its containing block plus any horizontal margin, padding and border (unless you’ve used box-sizing:border-box, in which case only margins are added to the 100% to change how its total width is calculated). This may be what you want, but most likely it isn’t.

Here is my solution:
$total_items = count($array_of_items);
$question_marks = array_fill(0, $total_items, '?');
$sql = 'SELECT * FROM foo WHERE bar IN (' . implode(',', $question_marks ). ')';
$stmt = $dbh->prepare($sql);
$stmt->execute(array_values($array_of_items));
Note the use of array_values. This can fix key ordering issues.
I was merging arrays of ids and then removing duplicate items. I had something like:
$ids = array(0 => 23, 1 => 47, 3 => 17);
And that was failing.
In short you have to do like this
repositories {
maven { url "http://maven.springframework.org/release" }
maven { url "https://maven.fabric.io/public" }
}
Detail:
You need to specify each maven URL in its own curly braces. Here is what I got working with skeleton dependencies for the web services project I’m going to build up:
apply plugin: 'java'
sourceCompatibility = 1.7
version = '1.0'
repositories {
maven { url "http://maven.springframework.org/release" }
maven { url "http://maven.restlet.org" }
mavenCentral()
}
dependencies {
compile group:'org.restlet.jee', name:'org.restlet', version:'2.1.1'
compile group:'org.restlet.jee', name:'org.restlet.ext.servlet',version.1.1'
compile group:'org.springframework', name:'spring-web', version:'3.2.1.RELEASE'
compile group:'org.slf4j', name:'slf4j-api', version:'1.7.2'
compile group:'ch.qos.logback', name:'logback-core', version:'1.0.9'
testCompile group:'junit', name:'junit', version:'4.11'
}
When you think your git is messed up, you can use this command to do everything up-to-date.
git rm -r --cached .
git add .
git commit -am 'git cache cleared'
git push
Also to revert back last commit use this :
git reset HEAD^ --hard
I think you have pointed out the most obvious difference. Apart from that,
the first doesn't need to lookup dict
which should make it a tiny bit faster
the second looks up dict
in locals()
and then globals()
and the finds the builtin, so you can switch the behaviour by defining a local called dict
for example although I can't think of anywhere this would be a good idea apart from maybe when debugging
Create your partial view something like:
@model YourModelType
<div>
<!-- HTML to render your object -->
</div>
Then in your view use:
@Html.Partial("YourPartialViewName", Model)
If you do not want a strongly typed partial view remove the @model YourModelType
from the top of the partial view and it will default to a dynamic
type.
Update
The default view engine will search for partial views in the same folder as the view calling the partial and then in the ~/Views/Shared folder. If your partial is located in a different folder then you need to use the full path. Note the use of ~/
in the path below.
@Html.Partial("~/Views/Partials/SeachResult.cshtml", Model)
As far as i know it wouldn't be possible to change the spark.executor.memory
at run time. If you are running a stand-alone version, with pyspark and graphframes, you can launch the pyspark REPL
by executing the following command:
pyspark --driver-memory 2g --executor-memory 6g --packages graphframes:graphframes:0.7.0-spark2.4-s_2.11
Be sure to change the SPARK_VERSION
environment variable appropriately regarding the latest released version of Spark

Not a technical answer but you might want to check the search box for the logcat. If there is any character inputted, your logcat will be empty as it will be searching for that certain character or word, and then if its not present, your logcat log will be totally empty.
For Bootstrap 3, there is
placement: 'auto right'
which is easier. By default, it will be right, but if the element is located in the right side of the screen, the popover will be left. So it should be:
$('.infopoint').popover({
trigger:'hover',
animation: false,
placement: 'auto right'
});
Simply, change
<textarea rows="15" cols="50" id="aboutDescription"
style="resize: none;"></textarea>
to
<textarea rows="15" cols="50" id="aboutDescription"
style="resize: none;" data-role="none"></textarea>
ie, add:
data-role="none"
On Windows plattform with server execute command:
netstat -a -b
look for sql server
processes and find port f.e 49198
Or easier. Connect with dbvisualizer, run netstat -a -b
find dbvis.exe process and get port.
You can use ObjectDataProvider
class and it's MethodName
property. It can look like this:
<Window.Resources>
<ObjectDataProvider x:Key="versionManager" ObjectType="{x:Type VersionManager}" MethodName="get_FilterString"></ObjectDataProvider>
</Window.Resources>
Declared object data provider can be used like this:
<TextBox Text="{Binding Source={StaticResource versionManager}}" />
The original poster is quoting a GCC compiler error message, but even by reading this thread, it's not clear that the error message is properly addressed - except by @pmg's answer. (+1, btw)
This is a GCC error message that means the return-value of a function is 'void', but that you are trying to assign it to a non-void variable.
Example:
void myFunction()
{
//...stuff...
}
int main()
{
int myInt = myFunction(); //Compile error!
return 0;
}
You aren't allowed to assign void to integers, or any other type.
In the OP's situation:
int a = srand(time(NULL));
...is not allowed. srand()
, according to the documentation, returns void.
This question is a duplicate of:
I am responding, despite it being duplicates, because this is the top result on Google for this error message. Because this thread is the top result, it's important that this thread gives a succinct, clear, and easily findable result.
sudo service mongod stop
sudo apt-get purge mongodb-org*
sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongodb
this worked for me
The best way to do this without more images :
public static void buttonEffect(View button){
button.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN: {
v.getBackground().setColorFilter(0xe0f47521,PorterDuff.Mode.SRC_ATOP);
v.invalidate();
break;
}
case MotionEvent.ACTION_UP: {
v.getBackground().clearColorFilter();
v.invalidate();
break;
}
}
return false;
}
});
}
Sven Marnach excellent solution is directly translatable into ElementTree which is part of recent Python distributions:
from xml.etree import ElementTree as ET
s = """<table>
<tr><th>Event</th><th>Start Date</th><th>End Date</th></tr>
<tr><td>a</td><td>b</td><td>c</td></tr>
<tr><td>d</td><td>e</td><td>f</td></tr>
<tr><td>g</td><td>h</td><td>i</td></tr>
</table>
"""
table = ET.XML(s)
rows = iter(table)
headers = [col.text for col in next(rows)]
for row in rows:
values = [col.text for col in row]
print(dict(zip(headers, values)))
same output as Sven Marnach's answer...
You can use DateFormat

Just like Perl,
loop1:
for (var i in set1) {
loop2:
for (var j in set2) {
loop3:
for (var k in set3) {
break loop2; // breaks out of loop3 and loop2
}
}
}
as defined in EMCA-262 section 12.12. [MDN Docs]
Unlike C, these labels can only be used for continue
and break
, as Javascript does not have goto
.
If you want to list only methods of a python class
import numpy as np
print(np.random.__all__)
The error message is so vague, for me I had this code:
var streamReader = new StreamReader(response.GetResponseStream());
var xmlSerializer = new XmlSerializer(typeof(aResponse));
theResponse = (bResponse) xmlSerializer.Deserialize(streamReader);
Notice xmlSerializer is instantiated with aResponse but on deserializing I accidentally casted it to bResonse.
From .NET 2.0 you shouldn't need to do this. If you do not explicitly set the Proxy property on a web request it uses the value of the static WebRequest.DefaultWebProxy. If you wanted to change the proxy being used by all subsequent WebRequests, you can set this static DefaultWebProxy property.
The default behaviour of WebRequest.DefaultWebProxy is to use the same underlying settings as used by Internet Explorer.
If you wanted to use different proxy settings to the current user then you would need to code
WebRequest webRequest = WebRequest.Create("http://stackoverflow.com/");
webRequest.Proxy = new WebProxy("http://proxyserver:80/",true);
or
WebRequest.DefaultWebProxy = new WebProxy("http://proxyserver:80/",true);
You should also remember the object model for proxies includes the concept that the proxy can be different depending on the destination hostname. This can make things a bit confusing when debugging and checking the property of webRequest.Proxy. Call
webRequest.Proxy.GetProxy(new Uri("http://google.com.au"))
to see the actual details of the proxy server that would be used.
There seems to be some debate about whether you can set webRequest.Proxy
or WebRequest.DefaultWebProxy = null
to prevent the use of any proxy. This seems to work OK for me but you could set it to new DefaultProxy()
with no parameters to get the required behaviour. Another thing to check is that if a proxy element exists in your applications config file, the .NET Framework will NOT use the proxy settings in Internet Explorer.
The MSDN Magazine article Take the Burden Off Users with Automatic Configuration in .NET gives further details of what is happening under the hood.
Wanted to add numexpr into the mix:
import numpy as np
import numexpr as ne
a = np.array([1, 3, 5, 6, 9, 10, 14, 15, 56])
np.where(ne.evaluate("(6 <= a) & (a <= 10)"))[0]
# array([3, 4, 5], dtype=int64)
Would only make sense for larger arrays with millions... or if you hitting a memory limits.
DataTables have an overloaded Select method that you can you to do this. See here: http://msdn.microsoft.com/en-us/library/way3dy9w.aspx
But the return val of the Select call is not a DataTable but an array of RowData objects. If you want to return a DataTable from your function you will have to build it from scratch based on that data array. Here is a post that addresses and provides a sample for both issues: http://social.msdn.microsoft.com/Forums/en-US/winformsdatacontrols/thread/157a4a0f-1324-4301-9725-3def95de2bf2/
Whatever is assigned to the files
variable is incorrect. Use the following code.
import glob
import os
list_of_files = glob.glob('/path/to/folder/*') # * means all if need specific format then *.csv
latest_file = max(list_of_files, key=os.path.getctime)
print(latest_file)
I know that this is already answered, but for the record and for anyone with the same requeriments as me I decided to post this related answer. The code is flooded with comments to explain the code.
Save the file as getopt.sh
:
#!/bin/bash
function get_variable_name_for_option {
local OPT_DESC=${1}
local OPTION=${2}
local VAR=$(echo ${OPT_DESC} | sed -e "s/.*\[\?-${OPTION} \([A-Z_]\+\).*/\1/g" -e "s/.*\[\?-\(${OPTION}\).*/\1FLAG/g")
if [[ "${VAR}" == "${1}" ]]; then
echo ""
else
echo ${VAR}
fi
}
function parse_options {
local OPT_DESC=${1}
local INPUT=$(get_input_for_getopts "${OPT_DESC}")
shift
while getopts ${INPUT} OPTION ${@};
do
[ ${OPTION} == "?" ] && usage
VARNAME=$(get_variable_name_for_option "${OPT_DESC}" "${OPTION}")
[ "${VARNAME}" != "" ] && eval "${VARNAME}=${OPTARG:-true}" # && printf "\t%s\n" "* Declaring ${VARNAME}=${!VARNAME} -- OPTIONS='$OPTION'"
done
check_for_required "${OPT_DESC}"
}
function check_for_required {
local OPT_DESC=${1}
local REQUIRED=$(get_required "${OPT_DESC}" | sed -e "s/\://g")
while test -n "${REQUIRED}"; do
OPTION=${REQUIRED:0:1}
VARNAME=$(get_variable_name_for_option "${OPT_DESC}" "${OPTION}")
[ -z "${!VARNAME}" ] && printf "ERROR: %s\n" "Option -${OPTION} must been set." && usage
REQUIRED=${REQUIRED:1}
done
}
function get_input_for_getopts {
local OPT_DESC=${1}
echo ${OPT_DESC} | sed -e "s/\([a-zA-Z]\) [A-Z_]\+/\1:/g" -e "s/[][ -]//g"
}
function get_optional {
local OPT_DESC=${1}
echo ${OPT_DESC} | sed -e "s/[^[]*\(\[[^]]*\]\)[^[]*/\1/g" -e "s/\([a-zA-Z]\) [A-Z_]\+/\1:/g" -e "s/[][ -]//g"
}
function get_required {
local OPT_DESC=${1}
echo ${OPT_DESC} | sed -e "s/\([a-zA-Z]\) [A-Z_]\+/\1:/g" -e "s/\[[^[]*\]//g" -e "s/[][ -]//g"
}
function usage {
printf "Usage:\n\t%s\n" "${0} ${OPT_DESC}"
exit 10
}
Then you can use it like this:
#!/bin/bash
#
# [ and ] defines optional arguments
#
# location to getopts.sh file
source ./getopt.sh
USAGE="-u USER -d DATABASE -p PASS -s SID [ -a START_DATE_TIME ]"
parse_options "${USAGE}" ${@}
echo ${USER}
echo ${START_DATE_TIME}
I recently needed to use a generic approach. I came across with this solution:
#!/bin/bash
# Option Description:
# -------------------
#
# Option description is based on getopts bash builtin. The description adds a variable name feature to be used
# on future checks for required or optional values.
# The option description adds "=>VARIABLE_NAME" string. Variable name should be UPPERCASE. Valid characters
# are [A-Z_]*.
#
# A option description example:
# OPT_DESC="a:=>A_VARIABLE|b:=>B_VARIABLE|c=>C_VARIABLE"
#
# -a option will require a value (the colon means that) and should be saved in variable A_VARIABLE.
# "|" is used to separate options description.
# -b option rule applies the same as -a.
# -c option doesn't require a value (the colon absense means that) and its existence should be set in C_VARIABLE
#
# ~$ echo get_options ${OPT_DESC}
# a:b:c
# ~$
#
# Required options
REQUIRED_DESC="a:=>REQ_A_VAR_VALUE|B:=>REQ_B_VAR_VALUE|c=>REQ_C_VAR_FLAG"
# Optional options (duh)

UPDATE
Consider avoiding createObjectURL()
method, while browsers are disabling support for it. Just attach MediaStream
object directly to the srcObject
property of HTMLMediaElement
e.g. <video>
element.
const mediaStream = new MediaStream();
const video = document.getElementById('video-player');
video.srcObject = mediaStream;
However, if you need to work with MediaSource
, Blob
or File
, you have to create a URL with URL.createObjectURL()
and assign it to HTMLMediaElement.src
.
Read more details here: https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/srcObject
Older Answer
I experienced same error, when I passed to createObjectURL
raw data:
window.URL.createObjectURL(data)
It has to be Blob
, File
or MediaSource
object, not data itself. This worked for me:
var binaryData = [];
binaryData.push(data);
window.URL.createObjectURL(new Blob(binaryData, {type: "application/zip"}))
Check also the MDN for more info: https://developer.mozilla.org/en-US/docs/Web/API/URL/createObjectURL
A quick way is to do
canvas.width = canvas.width
Idk how it works but it does!
It's not a better idea to override the core.common file of codeigniter. Because that's the more tested and system files....
I make a solution for this problem. In your ckeditor_helper.php file line- 65
if($k !== end (array_keys($data['config']))) {
$return .= ",";
}
Change this to-->
$segment = array_keys($data['config']);
if($k !== end($segment)) {
$return .= ",";
}
I think this is the best solution and then your problem notice will dissappear.
You could query the sys.tables database view to get out the names of the tables, and then use this query to build yourself another query to do the update on the back of that. For instance:
select 'select * from '+name from sys.tables
will give you a script that will run a select * against all the tables in the system catalog, you could alter the string in the select clause to do your update, as long as you know the column name is the same on all the tables you wish to update, so your script would look something like:
select 'update '+name+' set comments = ''(*)''+comments where comments like ''%comment to be updated%'' ' from sys.tables
You could also then predicate on the tables query to only include tables that have a name in a certain format, or are in a subset you want to create the update script for.
I wanted to answer to the following question which is a little bit different than this:
Best way to print messages on multiple lines
He wanted to show lines from repeated characters too. He wanted this output:
----------------------------------------
# Operator Micro-benchmarks
# Run_mode: short
# Num_repeats: 5
# Num_runs: 1000
----------------------------------------
You can create those lines inside f-strings with a multiplication, like this:
run_mode, num_repeats, num_runs = 'short', 5, 1000
s = f"""
{'-'*40}
# Operator Micro-benchmarks
# Run_mode: {run_mode}
# Num_repeats: {num_repeats}
# Num_runs: {num_runs}
{'-'*40}
"""
print(s)
a much more handy solution for your reference, it works perfect in all of my projects:
change your first line from
.navbar.navbar-fixed-top
to
.navbar.navbar-default.navbar-static-top
The AHK script is a great idea. Just for those interested I needed to change it a little bit to work for me:
SetTitleMatchMode,2 ;;; allows for a partial search
#IfWinActive, .py ;;; scope limiter to only python files
:b*:print ::print(){Left} ;;; I forget what b* does
#IfWinActive ;;; remove the scope limitation
After many struggles and to achive a general, flexible and more readable solution, in my case I ended up saving the ORs results into ENV variables and doing the ANDs of those variables.
# RESULT_ONE = A OR B
RewriteRule ^ - [E=RESULT_ONE:False]
RewriteCond ...A... [OR]
RewriteCond ...B...
RewriteRule ^ - [E=RESULT_ONE:True]
# RESULT_TWO = C OR D
RewriteRule ^ - [E=RESULT_TWO:False]
RewriteCond ...C... [OR]
RewriteCond ...D...
RewriteRule ^ - [E=RESULT_TWO:True]
# if ( RESULT_ONE AND RESULT_TWO ) then ( RewriteRule ...something... )
RewriteCond %{ENV:RESULT_ONE} =True
RewriteCond %{ENV:RESULT_TWO} =True
RewriteRule ...something...
Requirements:
it's quite handy with {data.table} and {stringr}
library(data.table)
library(stringr)
x[, lapply(.SD, function(xx) {str_replace_na(xx, 0)})]
FYI
The other answers are good, but if you want to do as List comprehension style
collection = ['a','b','c']
[item for item in reversed( collection ) ]

This question is very much answered by other people, I just want to make a point whenever deciding on any service to be in AWS is that understanding the use case for each and also see the solution that the service will provide in terms of the Well-Architected Framework, do you need High Availability, Fault Torelant, Cost optimization. This will help to decide on any kind of service to be used.
You need to change your code as below:

<span id="span_Id">Click the button to display the content.</span>
<button onclick="displayDate()">Click Me</button>
<script>
function displayDate() {
var span_Text = document.getElementById("span_Id").innerText;
alert (span_Text);
}
</script>
</body>
</html>
Sure, that is why python implements the following methods where the first parameter is a function:
In my experience, using the 32-bit version is more trouble-free. Unless you are working on applications that make heavy use of memory (mostly scientific computing, that uses more than 2GB memory), you're better off with 32-bit versions because:
You can comment section of a script using a conditional.
For example, the following script:
DEBUG=false
if ${DEBUG}; then
echo 1
echo 2
echo 3
echo 4
echo 5
fi
echo 6
echo 7
would output:
6
7
In order to uncomment the section of the code, you simply need to comment the variable:
#DEBUG=false
(Doing so would print the numbers 1 through 7.)

const [imageFile, setImageFile] = React.useState()
const onDrop = React.useCallback(

const file = acceptedFiles[0]
setImageFile(file)
// convert file to data: url
const reader = new FileReader()
reader.addEventListener('load', () => setImageUrl(String(reader.result)), false)
reader.readAsDataURL(file)
},
[setImageFile, setImageUrl]
)
const { getRootProps, getInputProps, isDragActive } = useDropzone({ onDrop })
return (
<div>
<div {...getRootProps()}>

Here's a recursive (tested lightly with bash and sh) function that traverses all subfolders of a given folder ($1) and using grep
searches for given string ($3) in given files ($2):
$ cat script.sh
#!/bin/sh
cd "$1"
loop () {
for i in *
do
if [ -d "$i" ]
then
# echo entering "$i"
cd "$i"
loop "$1" "$2"
fi
done
if [ -f "$1" ]
then
grep -l "$2" "$PWD/$1"
fi
cd ..
}
loop "$2" "$3"
Running it and an example output:
$ sh script start_folder filename search_string
/home/james/start_folder/dir2/filename
I'm not sure what your problem is (since you haven't told us), but I'm guessing at
a = Console.Read();
This will only read one character from your Console.
You can change your program to this. To make it more robust, accept more than 1 char input, and validate that the input is actually a number:
double a, b;
Console.WriteLine("istenen sayiyi sonuna .00 koyarak yaz");
if (double.TryParse(Console.ReadLine(), out a)) {
b = a * Math.PI;
Console.WriteLine("Sonuç " + b);
} else {
//user gave an illegal input. Handle it here.
}
I followed the steps in killthrush's answer and to my surprise it did not work. Logging in as sa I could see my Windows domain user and had made them a sysadmin, but when I tried logging in with Windows auth I couldn't see my login under logins, couldn't create databases, etc. Then it hit me. That login was probably tied to another domain account with the same name (with some sort of internal/hidden ID that wasn't right). I had left this organization a while back and then came back months later. Instead of re-activating my old account (which they might have deleted) they created a new account with the same domain\username and a new internal ID. Using sa I deleted my old login, re-added it with the same name and added sysadmin. I logged back in with Windows Auth and everything looks as it should. I can now see my logins (and others) and can do whatever I need to do as a sysadmin using my Windows auth login.
Well I can see two solutions here:
1) Follow the Docs-Tkinter install for Python (for Windows):
Tkinter (and, since Python 3.1, ttk) are included with all standard Python distributions. It is important that you use a version of Python supporting Tk 8.5 or greater, and ttk. We recommend installing the "ActivePython" distribution from ActiveState, which includes everything you'll need.
In your web browser, go to Activestate.com, and follow along the links to download the Community Edition of ActivePython for Windows. Make sure you're downloading a 3.1 or newer version, not a 2.x version.
Run the installer, and follow along. You'll end up with a fresh install of ActivePython, located in, e.g. C:\python32
. From a Windows command prompt, or the Start Menu's "Run..." command, you should then be able to run a Python shell via:
% C:\python32\python
This should give you the Python command prompt. From the prompt, enter these two commands:
>>> import tkinter
>>> tkinter._test()
This should pop up a small window; the first line at the top of the window should say "This is Tcl/Tk version 8.5"; make sure it is not 8.4!
2) Uninstall 64-bit Python and install 32 bit Python.
Try using ,
$('#points').val(request.responseText);
If you have red squiggles underneath the project in the Maven plugin, try clicking the "Reimport All Maven Projects" button (looks like a refresh symbol).
Note that if you still want to exclude a set, including things like slashes and special characters you can do the following:
var outString = sourceString.replace(/[`~!@#$%^&*()_|+\-=?;:'",.<>\{\}\[\]\\\/]/gi, '');
take special note that in order to also include the "minus" character, you need to escape it with a backslash like the latter group. if you don't it will also select 0-9 which is probably undesired.
Put $_SESSION['login_time'] = time();
into the previous authentication page.
And the snipped below in every other page where you want to check the session time-out.
if(time() - $_SESSION['login_time'] >= 1800){
session_destroy(); // destroy session.
header("Location: logout.php");
die(); // See https://thedailywtf.com/articles/WellIntentioned-Destruction
//redirect if the page is inactive for 30 minutes
}
else {
$_SESSION['login_time'] = time();
// update 'login_time' to the last time a page containing this code was accessed.
}
Edit : This only works if you already used the tweaks in other posts, or disabled Garbage Collection, and want to manually check the session duration.
Don't forget to add die()
after a redirect, because some scripts/robots might ignore it. Also, directly destroying the session with session_destroy()
instead of relying on a redirect for that might be a better option, again, in case of a malicious client or a robot.
select case when [am or _pm] ='PM' and datepart(HOUR,time_received)<>12
then dateadd(hour,12,time_received)
else time_received
END
from table
works
The root cause for the question asked was the deployment/job/replicasets spec attribute strategy->type
which defines what should happen when the pod will be destroyed (either implicitly or explicitly). In my case, it was Recreate
.
As per @nomad's answer, deleting the deployment/job/replicasets is the simple fix to avoid experimenting with deadly combos before messing up the cluster as a novice user.
Try the following commands to understand the behind the scene actions before jumping into debugging :
kubectl get all -A -o name
kubectl get events -A | grep <pod-name>
If you have a fixed height in your container, you can set line-height to be the same as height, and it will center vertically. Then just add text-align to center horizontally.
Here's an example: http://jsfiddle.net/Cthulhu/QHEnL/1/
EDIT
Your code should look like this:
.img_thumb {
float: left;
height: 120px;
margin-bottom: 5px;
margin-left: 9px;
position: relative;
width: 147px;
background-color: rgba(0, 0, 0, 0.5);
border-radius: 3px;
line-height:120px;
text-align:center;
}
.img_thumb img {
vertical-align: middle;
}
The images will always be centered horizontally and vertically, no matter what their size is. Here's 2 more examples with images with different dimensions:
http://jsfiddle.net/Cthulhu/QHEnL/6/
http://jsfiddle.net/Cthulhu/QHEnL/7/
UPDATE
It's now 2016 (the future!) and looks like a few things are changing (finally!!).
Back in 2014, Microsoft announced that it will stop supporting IE8 in all versions of Windows and will encourage all users to update to IE11 or Edge. Well, this is supposed to happen next Tuesday (12th January).
Why does this matter? With the announced death of IE8, we can finally start using CSS3 magic.
With that being said, here's an updated way of aligning elements, both horizontally and vertically:
.container {
position: relative;
}
.container .element {
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
}
Using this transform: translate();
method, you don't even need to have a fixed height in your container, it's fully dynamic. Your element has fixed height or width? Your container as well? No? It doesn't matter, it will always be centered because all centering properties are fixed on the child, it's independent from the parent. Thank you CSS3.
If you only need to center in one dimension, you can use translateY
or translateX
. Just try it for a while and you'll see how it works. Also, try to change the values of the translate
, you will find it useful for a bunch of different situations.
Here, have a new fiddle: https://jsfiddle.net/Cthulhu/1xjbhsr4/
For more information on transform
, here's a good resource.
Happy coding.
Using Accept header is really easy to get the format json or xml from the REST service.
This is my Controller, take a look produces section.
@RequestMapping(value = "properties", produces = {MediaType.APPLICATION_JSON_VALUE, MediaType.APPLICATION_XML_VALUE}, method = RequestMethod.GET)
public UIProperty getProperties() {
return uiProperty;
}
In order to consume the REST service we can use the code below where header can be MediaType.APPLICATION_JSON_VALUE or MediaType.APPLICATION_XML_VALUE
HttpHeaders headers = new HttpHeaders();
headers.add("Accept", header);
HttpEntity entity = new HttpEntity(headers);
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<String> response = restTemplate.exchange("http://localhost:8080/properties", HttpMethod.GET, entity,String.class);
return response.getBody();
Edit 01:
In order to work with application/xml
, add this dependency
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
</dependency>
Hiding an element and then showing it again within a setTimeout of 0 will force a redraw.
$('#page').hide();
setTimeout(function() {
$('#page').show();
}, 0);
Toggle both modals
$('#modalOne').modal('toggle');
$('#modalTwo').modal('toggle');
If you're using latest spring boot (with jdbc starter and Hikari) you'll run into:

self
is the self-reference in a Class. Your code is not in a class, you only have functions defined. You have to wrap your methods in a class, like below. To use the method main()
, you first have to instantiate an object of your class and call the function on the object.
Further, your function setavalue
should be in __init___
, the method called when instantiating an object. The next step you probably should look at is supplying the name as an argument to init, so you can create arbitrarily named objects of the Name
class ;)
class Name:
def __init__(self):
self.myname = "harry"
def printaname(self):
print "Name", self.myname
def main(self):
self.printaname()
if __name__ == "__main__":
objName = Name()
objName.main()
Have a look at the Classes chapter of the Python tutorial an at Dive into Python for further references.
You can use the following CSS to style the input element.
input[type="date"] {_x000D_
background-color: red;_x000D_

_x000D_
input[type="date"]::-webkit-clear-button {_x000D_

position: relative;_x000D_
}_x000D_
_x000D_
input[type="date"]::-webkit-inner-spin-button {_x000D_
height: 28px;_x000D_
}_x000D_
_x000D_
input[type="date"]::-webkit-calendar-picker-indicator {_x000D_

The accepted answer to how to replace multiple strings together in Oracle suggests using nested REPLACE
statements, and I don't think there is a better way.
If you are going to make heavy use of this, you could consider writing your own function:
CREATE TYPE t_text IS TABLE OF VARCHAR2(256);
CREATE FUNCTION multiple_replace(
in_text IN VARCHAR2, in_old IN t_text, in_new IN t_text
)
RETURN VARCHAR2
AS
v_result VARCHAR2(32767);
BEGIN
IF( in_old.COUNT <> in_new.COUNT ) THEN
RETURN in_text;
END IF;
v_result := in_text;
FOR i IN 1 .. in_old.COUNT LOOP
v_result := REPLACE( v_result, in_old(i), in_new(i) );
END LOOP;
RETURN v_result;
END;
and then use it like this:
SELECT multiple_replace( 'This is #VAL1# with some #VAL2# to #VAL3#',
NEW t_text( '#VAL1#', '#VAL2#', '#VAL3#' ),
NEW t_text( 'text', 'tokens', 'replace' )
)
FROM dual
This is text with some tokens to replace
If all of your tokens have the same format ('#VAL' || i || '#'
), you could omit parameter in_old
and use your loop-counter instead.
Adding Environment Variable simplified with screenshot. Check the below URL and you should be able to do without any trouble.
https://itsforlavanya.blogspot.com/2020/08/environment-variable-simple-7-steps-to.html
Use this it should help.
var currentUrl = "google.com"
var partOfUrl = currentUrl.substring(0, currentUrl.length-2)
webView.setWebViewClient(object: WebViewClient() {
override fun onLoadResource(WebView view, String url) {
//call loadUrl() method here
// also check if url contains partOfUrl, if not load it differently.
if(url.contains(partOfUrl, true)) {
//it should work if you reach inside this if scope.
} else if(!(currentUrl.startWith("w", true))) {
webView.loadurl("www.$currentUrl")
} else if(!(currentUrl.startWith("h", true))) {
webView.loadurl("https://$currentUrl")
} else {
//...
}
}
override fun onReceivedSslError(view: WebView?, handler: SslErrorHandler?, error: SslError?) {
// you can call again loadUrl from here too if there is any error.
}
// You should also override other override method for error such as
// onReceiveError to see how all these methods are called one after another and how
// they behave while debugging with break point.
}
Updated for Apache 2.4, for non-systemd (e.g., CentOS 6.x, Amazon Linux AMI) and for systemd (e.g., CentOS 7.x):
There are two ways of having the apache process reload the configuration, depending on what you want done with its current threads, either advise to exit when idle, or killing them directly.
Note that Apache recommends using apachectl -k
as the command, and for systemd, the command is replaced by httpd -k
apachectl -k graceful
or httpd -k graceful
Apache will advise its threads to exit when idle, and then apache reloads the configuration (it doesn't exit itself), this means statistics are not reset.
apachectl -k restart
or httpd -k restart
This is similar to stop, in that the process kills off its threads, but then the process reloads the configuration file, rather than killing itself.
I'd make a third suggestion, Google Closure Compiler (and also the Closure Linter). You can try it out online here.
The Closure Compiler is a tool for making JavaScript download and run faster. It is a true compiler for JavaScript. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript. It parses your JavaScript, analyzes it, removes dead code and rewrites and minimizes what's left. It also checks syntax, variable references, and types, and warns about common JavaScript pitfalls.
I learned how to do these sort of things reading "PRO HTML and CSS Design Patterns". The display:block
is the default display value for the div
, but I like to make it explicit. The container has to be the right type; position
attribute is fixed
, relative
, or absolute
.
.stretchedToMargin {_x000D_
display: block;_x000D_
position:absolute;_x000D_
height:auto;_x000D_
bottom:0;_x000D_
top:0;_x000D_
left:0;_x000D_
right:0;_x000D_
margin-top:20px;_x000D_
margin-bottom:20px;_x000D_
margin-right:80px;_x000D_
margin-left:80px;_x000D_
background-color: green;_x000D_
}
_x000D_
<div class="stretchedToMargin">_x000D_

Count all the DISTINCT program names by program type and push number
SELECT COUNT(DISTINCT program_name) AS Count,
program_type AS [Type]
FROM cm_production
WHERE push_number=@push_number
GROUP BY program_type
DISTINCT COUNT(*)
will return a row for each unique count. What you want is COUNT(DISTINCT <expression>)
: evaluates expression for each row in a group and returns the number of unique, non-null values.
You have to use:
abs() for int
fabs() for double
fabsf() for float
Above function will also work but you can also try something like this.
if(a<0)
{
a=-a;
}
I'm not sure what you're trying to do here:
npm install
alone in your home directory shouldn't do much -- it's not the root of a node app, so there's nothing to install, since there's no package.json.
There are two possible solutions:
1) cd
to a node app and run npm install
there. OR
2) if you're trying to install something as a command to use in the shell (You don't have a node application), npm install -g packagename
. -g
flag tells it to install in global namespace.
If you want to pass two values, you can use this approach
<asp:LinkButton ID="RemoveFroRole" Text="Remove From Role" runat="server"
CommandName='<%# Eval("UserName") %>' CommandArgument='<%# Eval("RoleName") %>'
OnClick="RemoveFromRole_Click" />
Basically I am treating {CommmandName,CommandArgument} as key value. Set both from database field. You will have to use OnClick event and use OnCommand
event in this case, which I think is more clean code.
div[disabled]
{
pointer-events: none;
opacity: 0.7;
}
The above code makes the contents of the div disabled. You can make div disabled by adding disabled attribute.
<div disabled>
/* Contents */
</div>
The compact answer:
SCSS refers to the main syntax supported by the Sass CSS pre-processor.
.scss
represent the standard syntax supported by Sass. SCSS is a superset of CSS..sass
represent the "older" syntax supported by Sass originating in the Ruby world.As far as how to use unwind segues in StoryBoard...
Step 1)
Go to the code for the view controller that you wish to unwind to and add this:
Objective-C
- (IBAction)unwindToViewControllerNameHere:(UIStoryboardSegue *)segue {
//nothing goes here
}
Be sure to also declare this method in your .h file in Obj-C
Swift
@IBAction func unwindToViewControllerNameHere(segue: UIStoryboardSegue) {
//nothing goes here
}
Step 2)
In storyboard, go to the view that you want to unwind from and simply drag a segue from your button or whatever up to the little orange "EXIT" icon at the top right of your source view.
There should now be an option to connect to "- unwindToViewControllerNameHere"
That's it, your segue will unwind when your button is tapped.
In my humble opinion the most elegant way to encode query params is to create an object with params like
const queryParams = { param1: 'value1', param2: 'value2' }
and then encode it using:
const queryString = new URLSearchParams(queryParams).toString()
as mentioned in this answer: https://stackoverflow.com/a/53171438/7284582
After reading all the answers and comments on this question, I thought to do a small experiment.
I generated 50,000 random booleans and called sum
and count
on them.
Here are my results:
>>> a = [bool(random.getrandbits(1)) for x in range(50000)]
>>> len(a)
50000
>>> a.count(False)
24884
>>> a.count(True)
25116
>>> def count_it(a):
... curr = time.time()
... counting = a.count(True)
... print("Count it = " + str(time.time() - curr))
... return counting
...
>>> def sum_it(a):
... curr = time.time()
... counting = sum(a)
... print("Sum it = " + str(time.time() - curr))
... return counting
...
>>> count_it(a)
Count it = 0.00121307373046875
25015
>>> sum_it(a)
Sum it = 0.004102230072021484
25015
Just to be sure, I repeated it several more times:
>>> count_it(a)
Count it = 0.0013530254364013672
25015
>>> count_it(a)
Count it = 0.0014507770538330078
25015
>>> count_it(a)
Count it = 0.0013344287872314453
25015
>>> sum_it(a)
Sum it = 0.003480195999145508
25015
>>> sum_it(a)
Sum it = 0.0035257339477539062
25015
>>> sum_it(a)
Sum it = 0.003350496292114258
25015
>>> sum_it(a)
Sum it = 0.003744363784790039
25015
And as you can see, count
is 3 times faster than sum
. So I would suggest to use count
as I did in count_it
.

You can try the QueryPerformanceCounter
native method. See http://www.pinvoke.net/default.aspx/kernel32/QueryPerformanceCounter.html for more information. This is what the Stopwatch
class uses.
See How to get timestamp of tick precision in .NET / C#? for more information.
Stopwatch.GetTimestamp()
gives access to this method:
public static long GetTimestamp() {
if(IsHighResolution) {
long timestamp = 0;
SafeNativeMethods.QueryPerformanceCounter(out timestamp);
return timestamp;
}
else {
return DateTime.UtcNow.Ticks;
}

From the OData documentation:
The OData Protocol is an application-level protocol for interacting with data via RESTful web services.
...
The OData Protocol is different from other REST-based web service approaches in that it provides a uniform way to describe both the data and the data model.
The answers presented here are largely technically correct, but even though the response list is long and this will be at the bottom I thought it was worth putting an actually correct response in here too, just in case somebody stumbles upon it and learns something valuable from it. It's not that the rest of the answers are wrong, it's just that they aren't right. And, to stop the hordes of trolls, yes, I know that technically these annotations are effectively the same thing and most interchangeable even unto spring 5. Now, for the right answer:
These three annotations are completely different things and are not interchangeable. You can tell that because there are three of them rather than just one. They are not intended to be interchangeable, they're just implemented that way out of elegance and convenience.
Modern programming is invention, art, technique, and communication, in varying proportions. The communication bit is usually very important because code is usually read much more often than its written. As a programmer you're not only trying to solve the technical problem, you're also trying to communicate your intent to future programmers who read your code. These programmers may not share your native language, nor your social environment, and it is possible that they may be reading your code 50-years in the future (it's not as unlikely as you may think). It's difficult to communicate effectively that far into the future. Therefore, it is vital that we use the clearest, most efficient, correct, and communicative language available to us. That we chose our words carefully to have maximum impact and to be as clear as possible as to our intent.
For example, it is vital that @Repository
is used when we're writing a repository, rather than @Component
. The latter is a very poor choice of annotation for a repository because it does not indicate that we're looking at a repository. We can assume that a repository is also a spring-bean, but not that a component is a repository. With @Repository
we are being clear and specific in our language. We are stating clearly that this is a repository. With @Component
we are leaving it to the reader to decide what type of component they are reading, and they will have to read the whole class (and possibly a tree of subclasses and interfaces) to infer meaning. The class could then possibly be misinterpreted by a reader in the distant future as not being a repository, and we would have been partially responsible for this mistake because we, who knew full well that this is a repository, failed to be specific in our language and communicate effectively our intent.
I won't go into the other examples, but will state as clearly as I can: these annotations are completely different things and should be used appropriately, as per their intent. @Repository
is for storage repositories and no other annotation is correct. @Service
is for services and no other annotation is correct. @Component
is for components that are neither repositories nor services, and to use either of these in its place would also be incorrect. It might compile, it might even run and pass your tests, but it would be wrong and I would think less of you (professionally) if you were to do this.
There are examples of this throughout spring (and programming in general). You must not use @Controller
when writing a REST API, because @RestController
is available. You must not use @RequestMapping
when @GetMapping
is a valid alternative. Etc. Etc. Etc. You must chose the most specific exact and correct language you can to communicate your intent to your readers, otherwise, you are introducing risks into your system, and risk has a cost.
I have found one solution, where admin()/others didn't worked.
const { promisify } = require('util');
const exec = promisify(require('child_process').exec)
async function test() {
var res = await exec('mongo --eval "db.adminCommand( { listDatabases: 1 }
)" --quiet')
return { res }
}
test()
.then(resp => {
console.log('All dbs', JSON.parse(resp.res.stdout).databases)
})
test()
It's obvious why you'd want to disable this: To force IntelliJ to include each and every import individually. It makes it easier for people to figure out exactly where classes you're using come from.
Click on the Settings "wrench" icon on the toolbar, open "Imports" under "Code Style", and check the "Use single class import" selection. You can also completely remove entries under "Packages to use import with *
", or specify a threshold value that only uses the "*
" when the individual classes from a package exceeds that threshold.
Update: in IDEA 13 "Use single class import" does not prevent wildcard imports. The solution is to go to Preferences
(? + , on macOS / Ctrl + Alt + S on Windows and Linux) > Editor > Code Style > Java > Imports tab
set Class count to use import with '*'
and Names count to use static import with '*'
to a higher value. Any value over 99 seems to work fine.
I fixed this bug changing the proxy configuration:

To print stacktrace of Error
in console in more readable way:
console.log(ex, ex.stack.split("\n"));
Example result:
[Error] [ 'Error',
' at repl:1:7',
' at REPLServer.self.eval (repl.js:110:21)',
' at Interface.<anonymous> (repl.js:239:12)',
' at Interface.EventEmitter.emit (events.js:95:17)',
' at Interface._onLine (readline.js:202:10)',
' at Interface._line (readline.js:531:8)',
' at Interface._ttyWrite (readline.js:760:14)',
' at ReadStream.onkeypress (readline.js:99:10)',
' at ReadStream.EventEmitter.emit (events.js:98:17)',
' at emitKey (readline.js:1095:12)' ]
Use Set in Python
>>> a = [2,4]
>>> b = [1,4,3]
>>> set(a) - set(b)
set([2])
Although the each function probably isn't necessary ...
$('select').each(function(){
$(this).find('option:first').prop('selected', 'selected');
});
works for me.
All aforementioned suggestions use %s
placeholder for subject. I'll recommend to use %B
because %s
formatting preserves new lines and multiple lines commit message appears squashed.
git log --pretty=format:"%h%x09%an%x09%ai%x09%B"
Like this: .
The .
means any character except newline (which sometimes is but often isn't included, check your regex flavour).
You can rewrite your expression as ^.{1,35}$
, which should match any line of length 1-35.
Use this code numberOnly will contain your desired output.
String str="sdfvsdf68fsdfsf8999fsdf09";
String numberOnly= str.replaceAll("[^0-9]", "");
I always use this code below for more readable
$('table').append([
'<tr>',
'<td>My Item 1</td>',
'<td>My Item 2</td>',
'<td>My Item 3</td>',
'<td>My Item 4</td>',
'</tr>'
].join(''));
or if it have tbody
$('table').find('tbody').append([
'<tr>',
'<td>My Item 1</td>',
'<td>My Item 2</td>',
'<td>My Item 3</td>',
'<td>My Item 4</td>',
'</tr>'
].join(''));

#polyNedir ul li { position:relative;padding-left:20px }
#polyNedir ul li:after{font-family:fontawesome;content:'\f111';position:absolute;left:0px;top:3px;color:#fff;font-size:10px;}
join(',', array_map(function (array $tag) { return $tag['tag_name']; }, $array))
Follow these steps, respectively for rename column migration file.
1- Is there Doctrine/dbal library in your project. If you don't have run the command first
composer require doctrine/dbal
2- create update migration file for update old migration file. Warning (need to have the same name)
php artisan make:migration update_oldFileName_table
for example my old migration file name: create_users_table update file name should : update_users_table
3- update_oldNameFile_table.php
Schema::table('users', function (Blueprint $table) {
$table->renameColumn('from', 'to');
});
'from' my old column name and 'to' my new column name
4- Finally run the migrate command
php artisan migrate

You can also load the context while defining the servlet itself (WebApplicationContext)
<servlet>
<servlet-name>admin</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/spring/*.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>admin</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
rather than (ApplicationContext)
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext*.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
or can do both together.
Drawback of just using WebApplicationContext is that it will load context only for this particular Spring entry point (DispatcherServlet
) where as with above mentioned methods context will be loaded for multiple entry points (Eg. Webservice Servlet, REST servlet
etc)
Context loaded by ContextLoaderListener
will infact be a parent context to that loaded specifically for DisplacherServlet . So basically you can load all your business service, data access or repository beans in application context and separate out your controller, view resolver beans to WebApplicationContext.
You can examine the url through several Request
fields:
Imagine your application is listening on the following application root:
http://www.example.com/myapplication
And a user requests the following URI:
http://www.example.com/myapplication/foo/page.html?x=y
In this case the values of the above mentioned attributes would be the following:
path /foo/page.html full_path /foo/page.html?x=y script_root /myapplication base_url http://www.example.com/myapplication/foo/page.html url http://www.example.com/myapplication/foo/page.html?x=y url_root http://www.example.com/myapplication/
You can easily extract the host part with the appropriate splits.
The cleanest way in modern Python >=3.6
, is to use an f-string with string formatting:
>>> var = 1.6
>>> f"{var:.15f}"
'1.600000000000000'
There's actually a good reason:
The non-static access does not always work, for reasons of ambiguity.
Suppose we have two classes, A and B, the latter being a subclass of A, with static fields with the same name:
public class A {
public static String VALUE = "Aaa";
}
public class B extends A {
public static String VALUE = "Bbb";
}
Direct access to the static variable:
A.VALUE (="Aaa")
B.VALUE (="Bbb")
Indirect access using an instance (gives a compiler warning that VALUE should be statically accessed):
new B().VALUE (="Bbb")
So far, so good, the compiler can guess which static variable to use, the one on the superclass is somehow farther away, seems somehow logical.
Now to the point where it gets tricky: Interfaces can also have static variables.
public interface C {
public static String VALUE = "Ccc";
}
public interface D {
public static String VALUE = "Ddd";
}
Let's remove the static variable from B, and observe following situations:
B implements C, D
B extends A implements C
B extends A implements C, D
B extends A implements C
where A implements D
B extends A implements C
where C extends D
The statement new B().VALUE
is now ambiguous, as the compiler cannot decide which static variable was meant, and will report it as an error:
error: reference to VALUE is ambiguous
both variable VALUE in C and variable VALUE in D match
And that's exactly the reason why static variables should be accessed in a static way.
To read a README.md file in the terminal I use:
pandoc README.md | lynx -stdin
Pandoc outputs it in HTML format, which Lynx renders in your terminal.
It works great: It fills my terminal, shortcuts are shown below, I can scroll through, and the links work! There is only one font size though, but the colors + indentation + alignment make up for that.
Installation:
sudo apt-get install pandoc lynx
Command + Space
Search for Xcode
Open it and accept license
Then run again from terminal xcode-select --install
