The mail server on CentOS 6 and other IPv6 capable server platforms may be bound to IPv6 localhost (::1) instead of IPv4 localhost (127.0.0.1).
Typical symptoms:
[root@host /]# telnet 127.0.0.1 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
[root@host /]# telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 host ESMTP Exim 4.72 Wed, 14 Aug 2013 17:02:52 +0100
[root@host /]# netstat -plant | grep 25
tcp 0 0 :::25 :::* LISTEN 1082/exim
If this happens, make sure that you don't have two entries for localhost
in /etc/hosts
with different IP addresses, like this (bad) example:
[root@host /]# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost localhost4.localdomain4 localhost4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
To avoid confusion, make sure you only have one entry for localhost
, preferably an IPv4 address, like this:
[root@host /]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4.localdomain4 localhost4
::1 localhost6 localhost6.localdomain6
There is a nice C# wrapper for the Yahoo.Finance API at http://code.google.com/p/yahoo-finance-managed/ that will get you there. Unfortunately there is no direct way to download the ticker list but the following creates the list by iterating through the alphabetical groups:
AlphabeticIDIndexDownload dl1 = new AlphabeticIDIndexDownload();
dl1.Settings.TopIndex = null;
Response<AlphabeticIDIndexResult> resp1 = dl1.Download();
writeStream.WriteLine("Id|Isin|Name|Exchange|Type|Industry");
foreach (var alphabeticalIndex in resp1.Result.Items)
{
AlphabeticalTopIndex topIndex = (AlphabeticalTopIndex) alphabeticalIndex;
dl1.Settings.TopIndex = topIndex;
Response<AlphabeticIDIndexResult> resp2 = dl1.Download();
foreach (var index in resp2.Result.Items)
{
IDSearchDownload dl2 = new IDSearchDownload();
Response<IDSearchResult> resp3 = dl2.Download(index);
int i = 0;
foreach (var item in resp3.Result.Items)
{
writeStream.WriteLine(item.ID + "|" + item.ISIN + "|" + item.Name + "|" + item.Exchange + "|" + item.Type + "|" + item.Industry);
}
}
}
It gave me a list of about 75,000 securities in about 4 mins.
Following the greenhoorn's answer, you can use "Extensions" like this:
public static class HttpClientExtensions
{
public static HttpClient AddTokenToHeader(this HttpClient cl, string token)
{
//int timeoutSec = 90;
//cl.Timeout = new TimeSpan(0, 0, timeoutSec);
string contentType = "application/json";
cl.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(contentType));
cl.DefaultRequestHeaders.Add("Authorization", String.Format("Bearer {0}", token));
var userAgent = "d-fens HttpClient";
cl.DefaultRequestHeaders.Add("User-Agent", userAgent);
return cl;
}
}
And use:
string _tokenUpdated = "TOKEN";
HttpClient _client;
_client.AddTokenToHeader(_tokenUpdated).GetAsync("/api/values")
Try making your constructor private like this:
private Foo newClass = new Foo();
after struggling with this for a couple of hours, I've found that you can only use one db helper object per db execution. For example,
for(int x = 0; x < someMaxValue; x++)
{
db = new DBAdapter(this);
try
{
db.addRow
(
NamesStringArray[i].toString(),
StartTimeStringArray[i].toString(),
EndTimeStringArray[i].toString()
);
}
catch (Exception e)
{
Log.e("Add Error", e.toString());
e.printStackTrace();
}
db.close();
}
as apposed to:
db = new DBAdapter(this);
for(int x = 0; x < someMaxValue; x++)
{
try
{
// ask the database manager to add a row given the two strings
db.addRow
(
NamesStringArray[i].toString(),
StartTimeStringArray[i].toString(),
EndTimeStringArray[i].toString()
);
}
catch (Exception e)
{
Log.e("Add Error", e.toString());
e.printStackTrace();
}
}
db.close();
creating a new DBAdapter each time the loop iterates was the only way I could get my strings into a database through my helper class.
I'm just now learning C++, but editing some of the code previously posted, I'd probably use something like this. This gives you the flexibility to replace 1 or multiple instances, and also lets you specify the start point.
using namespace std;
// returns number of replacements made in string
long strReplace(string& str, const string& from, const string& to, size_t start = 0, long count = -1) {
if (from.empty()) return 0;
size_t startpos = str.find(from, start);
long replaceCount = 0;
while (startpos != string::npos){
str.replace(startpos, from.length(), to);
startpos += to.length();
replaceCount++;
if (count > 0 && replaceCount >= count) break;
startpos = str.find(from, startpos);
}
return replaceCount;
}

On some investigation, the answer appears to be (a).
When I go to change the settings, the settings file goes into a .vscode directory in my project directory.
It seems that you are mixing different Pythons here (Python 2.x vs. Python 3.x)... This is basically correct:
nb = input('Choose a number: ')
The problem is that it is only supported in Python 3. As @sharpner answered, for older versions of Python (2.x), you have to use the function raw_input
:
nb = raw_input('Choose a number: ')
If you want to convert that to a number, then you should try:
number = int(nb)
... though you need to take into account that this can raise an exception:
try:
number = int(nb)
except ValueError:
print("Invalid number")
And if you want to print the number using formatting, in Python 3 str.format()
is recommended:
print("Number: {0}\n".format(number))
Instead of:
print('Number %s \n' % (nb))
But both options (str.format()
and %
) do work in both Python 2.7 and Python 3.
Try this:
alert("Successful Message");
location.reload();
This works for me in firefox

key, value = max(stats.iteritems(), key=lambda x:x[1])
If you don't care about value (I'd be surprised, but) you can do:
key, _ = max(stats.iteritems(), key=lambda x:x[1])
I like the tuple unpacking better than a [0] subscript at the end of the expression. I never like the readability of lambda expressions very much, but find this one better than the operator.itemgetter(1) IMHO.
Every time the randint() method is called inside the for loop a different seed is set and a sequence is generated according to the time. But as for loop runs fast in your computer in a small time the seed is almost same and a very similar sequence is generated to the past one due to the time. So setting the seed outside the randint() method is enough.
package main
import (
"bytes"
"fmt"
"math/rand"
"time"
)
var r = rand.New(rand.NewSource(time.Now().UTC().UnixNano()))
func main() {
fmt.Println(randomString(10))
}
func randomString(l int) string {
var result bytes.Buffer
var temp string
for i := 0; i < l; {
if string(randInt(65, 90)) != temp {
temp = string(randInt(65, 90))
result.WriteString(temp)
i++
}
}
return result.String()
}
func randInt(min int, max int) int {
return min + r.Intn(max-min)
}
I know this is an ancient thread but I wanted to add a few nuances.
There are Maven artifacts, repository manager artifacts and then there are Maven Artifact
s.
A Maven artifact is just as other commenters/responders say: it is a thing that is spat out by building a Maven project. That could be a .jar
file, or a .war
file, or a .zip
file, or a .dll
, or what have you.
A repository manager artifact is a thing that is, well, managed by a repository manager. A repository manager is basically a highly performant naming service for software executables and libraries. A repository manager doesn't care where its artifacts come from (maybe they came from a Maven build, or a local file, or an Ant build, or a by-hand compilation...).
A Maven Artifact
is a Java class that represents the kind of "name" that gets dereferenced by a repository manager into a repository manager artifact. When used in this sense, an Artifact
is just a glorified name made up of such parts as groupId
, artifactId
, version
, scope
, classifier
and so on.
To put it all together:
Artifact
s by way of its <dependency>
elements.Artifact
s into files by instructing the repository manager to send it some repository manager artifacts that correspond to the internal Artifact
s.Hope that helps.

TL;DR;
git stash-staged
After creating an alias:
git config --global alias.stash-staged '!bash -c "git stash -- \$(git diff --staged --name-only)"'
Here git diff
returns list of --staged
files --name-only
And then we pass this list as pathspec
to git stash
commad.
From man git stash
:
git stash [--] [<pathspec>...]
<pathspec>...
The new stash entry records the modified states only for the files
that match the pathspec. The index entries and working tree
files are then rolled back to the state in HEAD only for these
files, too, leaving files that do not match the pathspec intact.
You could also use a CSS "calc" to get the same effect instead of using the negative margin or transform properties (in case you want to use those properties for anything else).
.hero:after,
.hero:after {
z-index: -1;
position: absolute;
top: 98.1%;
left: calc(50% - 25px);
content: '';
width: 0;
height: 0;
border-top: solid 50px #e15915;
border-left: solid 50px transparent;
border-right: solid 50px transparent;
}
I like PyInstaller - especially the "windowed" variant:
pyinstaller --onefile --windowed myscript.py
It will create one single *.exe file in a distination/folder.
Did you try using t.Text
?
More simple way...:
Dim dt As DataTable = DirectCast(GridView1.DataSource, DataTable)
Dim dv As New DataView(dt)
If GridView1.Attributes("dir") = SortDirection.Ascending Then
dv.Sort = e.SortExpression & " DESC"
GridView1.Attributes("dir") = SortDirection.Descending
Else
GridView1.Attributes("dir") = SortDirection.Ascending
dv.Sort = e.SortExpression & " ASC"
End If
GridView1.DataSource = dv
GridView1.DataBind()

You can use the function last_insert_rowid()
:
The
last_insert_rowid()
function returns theROWID
of the last row insert from the database connection which invoked the function. Thelast_insert_rowid()
SQL function is a wrapper around thesqlite3_last_insert_rowid()
C/C++ interface function.
I often use row_number() as a quick way to discard duplicate records from my select statements. Just add a where clause. Something like...
select a,b,rn
from (select a, b, row_number() over (partition by a,b order by a,b) as rn
from table)
where rn=1;
You need to call it explicitly. In the example above, bradhouse has given you all the steps to write a custom constraint.
Add this code in your caller class.
ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
validator = factory.getValidator();
Set<ConstraintViolation<yourObjectClass>> constraintViolations = validator.validate(yourObject);
in the above case it would be
Set<ConstraintViolation<AccountCreateForm>> constraintViolations = validator.validate(objAccountCreateForm);
The solution can be optimized in following way: Firstly, use a private inner class as the scope for the fields is to be the enclosing class TestPeople so as the implementation of class People won't get exposed to outer world. This can be understood in terms of creating an APIthat expects a sorted list of people Secondly, using the Lamba expression(java 8) which reduces the code, hence development effort
Hence code would be as below:
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
public class TestPeople {
public static void main(String[] args) {
ArrayList<People> peps = new ArrayList<>();// Be specific, to avoid
// classCast Exception
TestPeople test = new TestPeople();
peps.add(test.new People(123, "M", 14.25));
peps.add(test.new People(234, "M", 6.21));
peps.add(test.new People(362, "F", 9.23));
peps.add(test.new People(111, "M", 65.99));
peps.add(test.new People(535, "F", 9.23));
/*
* Collections.sort(peps);
*
* for (int i = 0; i < peps.size(); i++){
* System.out.println(peps.get(i)); }
*/
// The above code can be replaced by followin:
peps.sort((People p1, People p2) -> p1.getid() - p2.getid());
peps.forEach((p) -> System.out.println(" " + p.toString()));
}
private class People {
private int id;
@Override
public String toString() {
return "People [id=" + id + ", info=" + info + ", price=" + price + "]";
}
private String info;
private double price;
public People(int newid, String newinfo, double newprice) {
setid(newid);
setinfo(newinfo);
setprice(newprice);
}
public int getid() {
return id;
}
public void setid(int id) {
this.id = id;
}
public String getinfo() {
return info;
}
public void setinfo(String info) {
this.info = info;
}
public double getprice() {
return price;
}
public void setprice(double price) {
this.price = price;
}
}
}
I think that moving last operator to the beginning of the next line is a good practice. That way you know right away the purpose of the second line, even it doesn't start with an operator. I also recommend 2 indentation spaces (2 tabs) for a previously broken tab, to differ it from the normal indentation. That is immediately visible as continuing previous line. Therefore I suggest this:
private static final Map<Class<? extends Persistent>, PersistentHelper> class2helper
= new HashMap<Class<? extends Persistent>, PersistentHelper>();
The methods you're calling on the Boolean
class don't check whether the string contains a valid boolean value, but they return the boolean value that represents the contents of the string: put "true" in string, they return true
, put "false" in string, they return false
.
You can surely use these methods, however, to check for valid boolean values, as I'd expect them to throw an exception if the string contains "hello" or something not boolean.
Wrap that in a Method ContainsBoolString
and you're go.
EDIT
By the way, in C# there are methods like bool Int32.TryParse(string x, out int i)
that perform the check whether the content can be parsed and then return the parsed result.
int i;
if (Int32.TryParse("Hello", out i))
// Hello is an int and its value is in i
else
// Hello is not an int
Benchmarks indicate they are way faster than the following:
int i;
try
{
i = Int32.Parse("Hello");
// Hello is an int and its value is in i
}
catch
{
// Hello is not an int
}
Maybe there are similar methods in Java? It's been a while since I've used Java...
You need to catch the return value.
The DateTime.AddDays method returns an object who's value is the sum of the date and time of the instance and the added value.
endDate = endDate.AddDays(addedDays);
Firstly, I am not an authority on WebClient vs. HttpClient, specifically. Secondly, from your comments above, it seems to suggest that WebClient is Sync ONLY whereas HttpClient is both.
I did a quick performance test to find how WebClient (Sync calls), HttpClient (Sync and Async) perform. and here are the results.
I see that as a huge difference when thinking for future, i.e. long running processes, responsive GUI, etc. (add to the benefit you suggest by framework 4.5 - which in my actual experience is hugely faster on IIS)
I managed to download the file generated by the rest API URL much easier with this kind of code which worked just fine on my local:

super(props);
this.handleSubmit = this.handleSubmit.bind(this);
}
handleSubmit(event) {
event.preventDefault();
const form = event.target;
let queryParam = buildQueryParams(form.elements);
let url = 'http://localhost:8080/...whatever?' + queryParam;
fetch(url, {
method: 'GET',
headers: {
// whatever
},
})
.then(function (response) {
return response.blob();
}
)
.then(function(blob) {
saveAs(blob, "yourFilename.xlsx");
})
.catch(error => {
//whatever
})
}
render() {
return (

}
}
function buildQueryParams(formElements) {
let queryParam = "";
//do code here
return queryParam;
}
export default MyForm;
Don't know why @Janos deleted his answer, but it's correct: your data frame Train
doesn't have a column named pre
. When you pass a formula and a data frame to a model-fitting function, the names in the formula have to refer to columns in the data frame. Your Train
has columns called residual.sugar
, total.sulfur
, alcohol
and quality
. You need to change either your formula or your data frame so they're consistent with each other.
And just to clarify: Pre
is an object containing a formula. That formula contains a reference to the variable pre
. It's the latter that has to be consistent with the data frame.
The simplest defenition is ; padding is a space given inside the border of the container element and margin is given outside. For a element which is not a container, padding may not make much sense, but margin defenitly will help to arrange it.
Try these ...
Option1
window.location=document.referrer;
Option2
window.location.reload(history.back());
In newer versions(>=1.8.0) of docker, you can do this
docker build -f Dockerfile.db .
docker build -f Dockerfile.web .
A big save.
EDIT: update versions per raksja's comment
EDIT: comment from @vsevolod: it's possible to get syntax highlighting in VS code by giving files .Dockerfile extension(instead of name) e.g. Prod.Dockerfile, Test.Dockerfile etc.
I had the same problem, it was solved after re-installing my Theme
I know there are multiple ways to achieve this as per solutions shared above. I haven't tried all of them but some third party services lack clarity around what are all tasks being run in the background. I have achieved this through a powershell script similar to the one mentioned as windows batch file. I have scheduled it using Windows Tasks Scheduler to run every minute. This has been quite efficient and transparent so far. The advantage I have here is that I am checking the process explicitly before starting it again. This wouldn't cause much overhead to the CPU on the server. Also you don't have to explicitly place the file into the startup folders.

There are multiple ways to do this and from your question it's nor clear what you need.
1. If you need environment variable to be defined PER TASK ONLY, you do this:
- hosts: dev tasks: - name: Echo my_env_var shell: "echo $MY_ENV_VARIABLE" environment: MY_ENV_VARIABLE: whatever_value - name: Echo my_env_var again shell: "echo $MY_ENV_VARIABLE"
Note that MY_ENV_VARIABLE
is available ONLY for the first task, environment
does not set it permanently on your system.
TASK: [Echo my_env_var] *******************************************************
changed: [192.168.111.222] => {"changed": true, "cmd": "echo $MY_ENV_VARIABLE", ... "stdout": "whatever_value"}
TASK: [Echo my_env_var again] *************************************************
changed: [192.168.111.222] => {"changed": true, "cmd": "echo $MY_ENV_VARIABLE", ... "stdout": ""}
Hopefully soon using environment
will also be possible on play level, not only task level as above.
There's currently a pull request open for this feature on Ansible's GitHub: https://github.com/ansible/ansible/pull/8651
UPDATE: It's now merged as of Jan 2, 2015.
2. If you want permanent environment variable + system wide / only for certain user
You should look into how you do it in your Linux distribution / shell, there are multiple places for that. For example in Ubuntu you define that in files like for example:
~/.profile
/etc/environment
/etc/profile.d
directoryYou will find Ubuntu docs about it here: https://help.ubuntu.com/community/EnvironmentVariables
After all for setting environment variable in ex. Ubuntu you can just use lineinfile
module from Ansible and add desired line to certain file. Consult your OS docs to know where to add it to make it permanent.
To add on, I have used function objects to fit an existing legacy method to the command pattern; (only place where the beauty of OO paradigm true OCP I felt ); Also adding here the related function adapter pattern.
Suppose your method has the signature:
int CTask::ThreeParameterTask(int par1, int par2, int par3)
We will see how we can fit it for the Command pattern - for this, first, you have to write a member function adapter so that it can be called as a function object.
Note - this is ugly, and may be you can use the Boost bind helpers etc., but if you can't or don't want to, this is one way.
// a template class for converting a member function of the type int function(int,int,int)
//to be called as a function object
template<typename _Ret,typename _Class,typename _arg1,typename _arg2,typename _arg3>
class mem_fun3_t
{
public:
explicit mem_fun3_t(_Ret (_Class::*_Pm)(_arg1,_arg2,_arg3))
:m_Ptr(_Pm) //okay here we store the member function pointer for later use
{}
//this operator call comes from the bind method
_Ret operator()(_Class *_P, _arg1 arg1, _arg2 arg2, _arg3 arg3) const
{
return ((_P->*m_Ptr)(arg1,arg2,arg3));
}
private:
_Ret (_Class::*m_Ptr)(_arg1,_arg2,_arg3);// method pointer signature
};
Also, we need a helper method mem_fun3
for the above class to aid in calling.
template<typename _Ret,typename _Class,typename _arg1,typename _arg2,typename _arg3>
mem_fun3_t<_Ret,_Class,_arg1,_arg2,_arg3> mem_fun3 ( _Ret (_Class::*_Pm) (_arg1,_arg2,_arg3) )
{
return (mem_fun3_t<_Ret,_Class,_arg1,_arg2,_arg3>(_Pm));
}
Now, in order to bind the parameters, we have to write a binder function. So, here it goes:
template<typename _Func,typename _Ptr,typename _arg1,typename _arg2,typename _arg3>
class binder3
{
public:
//This is the constructor that does the binding part
binder3(_Func fn,_Ptr ptr,_arg1 i,_arg2 j,_arg3 k)
:m_ptr(ptr),m_fn(fn),m1(i),m2(j),m3(k){}
//and this is the function object
void operator()() const
{
m_fn(m_ptr,m1,m2,m3);//that calls the operator
}
private:
_Ptr m_ptr;
_Func m_fn;
_arg1 m1; _arg2 m2; _arg3 m3;
};
And, a helper function to use the binder3 class - bind3
:
//a helper function to call binder3
template <typename _Func, typename _P1,typename _arg1,typename _arg2,typename _arg3>
binder3<_Func, _P1, _arg1, _arg2, _arg3> bind3(_Func func, _P1 p1,_arg1 i,_arg2 j,_arg3 k)
{
return binder3<_Func, _P1, _arg1, _arg2, _arg3> (func, p1,i,j,k);
}
Now, we have to use this with the Command class; use the following typedef:
typedef binder3<mem_fun3_t<int,T,int,int,int> ,T* ,int,int,int> F3;
//and change the signature of the ctor
//just to illustrate the usage with a method signature taking more than one parameter
explicit Command(T* pObj,F3* p_method,long timeout,const char* key,
long priority = PRIO_NORMAL ):
m_objptr(pObj),m_timeout(timeout),m_key(key),m_value(priority),method1(0),method0(0),
method(0)
{
method3 = p_method;
}
Here is how you call it:
F3 f3 = PluginThreadPool::bind3( PluginThreadPool::mem_fun3(
&CTask::ThreeParameterTask), task1,2122,23 );
Note: f3();
will call the method task1->ThreeParameterTask(21,22,23);

For checking type conversions in version 3, you can go to their github and check into the different liquibase types and check the method toDatabaseDataType. For example, for Boolean, you can check here:
For version 2.0.x, the conversion seems to be into database specific classes. For example, for Mysql:
Just passing by callbacks is not enough. You have to use settimer for example, to make function async.
Examples: Not async functions:
function a() {
var a = 0;
for(i=0; i<10000000; i++) {
a++;
};
b();
};
function b() {
var a = 0;
for(i=0; i<10000000; i++) {
a++;
};
c();
};
function c() {
for(i=0; i<10000000; i++) {
};
console.log("async finished!");
};
a();
console.log("This should be good");
If you will run above example, This should be good, will have to wait untill those functions will finish to work.
Pseudo multithread (async) functions:
function a() {
setTimeout ( function() {
var a = 0;
for(i=0; i<10000000; i++) {
a++;
};
b();
}, 0);
};
function b() {
setTimeout ( function() {
var a = 0;
for(i=0; i<10000000; i++) {
a++;
};
c();
}, 0);
};
function c() {
setTimeout ( function() {
for(i=0; i<10000000; i++) {
};
console.log("async finished!");
}, 0);
};
a();
console.log("This should be good");
This one will be trully async. This should be good will be writen before async finished.
To get the last element, simply use the size of the list as the second parameter. So for example, if you have 35 files, and you want the last five, you would do:
dataList.subList(30, 35);
A guaranteed safe way to do this is:
dataList.subList(Math.max(0, first), Math.min(dataList.size(), last) );
import datetime
a = datetime.datetime.today().year
or even (as Lennart suggested)
a = datetime.datetime.now().year
or even
a = datetime.date.today().year

As you might have already about knew the error. This is due to trying to access the empty array or trying to access the value of empty key of array. In my project, I am dealing with this error with counting the array and displaying result.
You can do it like this:
if(count($votes) == '0'){
echo 'Sorry, no votes are available at the moment.';
}
else{
//do the stuff with votes
}
count($votes)
counts the $votes
array. If it is equal to zero (0)
, you can display your custom message or redirect to certain page else you can do stuff with $votes
. In this way you can remove the Notice: Undefined offset: 0
in notice in PHP.
You should install IIS sub components from
Control Panel
-> Programs and Features
-> Turn Windows features on or off
Internet Information Services
has subsection World Wide Web Services
/ Application Development Features
There you must check ASP.NET
(.NET Extensibility
, ISAPI Extensions
, ISAPI Filters
will be selected automatically). Double check that specific versions are checked. Under Windows Server 2012 R2, these options are split into 4 & 4.5.
Run from cmd
:
%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ir
Finally check in IIS manager, that your application uses application pool with .NET framework version v4.0.

The Instagram API is meant for not only you, but for any Instagram user to potentially authenticate with your app. I followed the instructions on the Instagram Dev website. Using the first (Explicit) method, I was able to do this quite easily on the server.
Step 1) Add a link or button to your webpage which a user could click to initiate the authentication process:
<a href="https://api.instagram.com/oauth/authorize/?client_id=YOUR_CLIENT_ID&redirect_uri=YOUR_REDIRECT_URI&response_type=code">Get Started</a>
YOUR_CLIENT_ID
and YOUR_REDIRECT_URI
will be given to you after you successfully register your app in the Instagram backend, along with YOUR_CLIENT_SECRET
used below.
Step 2) At the URI that you defined for your app, which is the same as YOUR_REDIRECT_URI
, you need to accept the response from the Instagram server. The Instagram server will feed you back a code
variable in the request. Then you need to use this code
and other information about your app to make another request directly from your server to obtain the access_token
. I did this in python using Django framework, as follows:
direct django to the response
function in urls.py
:
from django.conf.urls import url
from . import views
app_name = 'main'
urlpatterns = [
url(r'^$', views.index, name='index'),
url(r'^response/', views.response, name='response'),
]
Here is the response
function, handling the request, views.py
:
from django.shortcuts import render
import urllib
import urllib2
import json
def response(request):
if 'code' in request.GET:
url = 'https://api.instagram.com/oauth/access_token'
values = {
'client_id':'YOUR_CLIENT_ID',
'client_secret':'YOUR_CLIENT_SECRET',
'redirect_uri':'YOUR_REDIRECT_URI',
'code':request.GET.get('code'),
'grant_type':'authorization_code'
}
data = urllib.urlencode(values)
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
response_string = response.read()
insta_data = json.loads(response_string)
if 'access_token' in insta_data and 'user' in insta_data:
#authentication success
return render(request, 'main/response.html')
else:
#authentication failure after step 2
return render(request, 'main/auth_error.html')
elif 'error' in req.GET:
#authentication failure after step 1
return render(request, 'main/auth_error.html')
This is just one way, but the process should be almost identical in PHP or any other server-side language.
You could instantiate "AnnotationConfigApplicationContext" by passing all your service classes as parameters.
@Component
public class MyServiceFactory {
private ApplicationContext applicationContext;
public MyServiceFactory() {
applicationContext = new AnnotationConfigApplicationContext(
MyServiceOne.class,
MyServiceTwo.class,
MyServiceThree.class,
MyServiceDefault.class,
LocationService.class
);
/* I have added LocationService.class because this component is also autowired */
}
public MyService getMyService(String service) {
if ("one".equalsIgnoreCase(service)) {
return applicationContext.getBean(MyServiceOne.class);
}
if ("two".equalsIgnoreCase(service)) {
return applicationContext.getBean(MyServiceTwo.class);
}
if ("three".equalsIgnoreCase(service)) {
return applicationContext.getBean(MyServiceThree.class);
}
return applicationContext.getBean(MyServiceDefault.class);
}
}

I'd stay with two different interfaces.
You said that 'I want to group my service executors under a common interface... It also seems overkill creating two separate interfaces for the two different service calls... A class will only implement one of these interfaces'
It's not clear what is the reason to have a single interface then. If you want to use it as a marker, you can just exploit annotations instead.
Another point is that there is a possible case that your requirements change and method(s) with another signature appears at the interface. Of course it's possible to use Adapter pattern then but it would be rather strange to see that particular class implements interface with, say, three methods where two of them trow UnsupportedOperationException. It's possible that the forth method appears etc.
\p{L}
matches a single code point in the category "letter".
\p{N}
matches any kind of numeric character in any script.

You can use WebView and create a app that put your site inside. https://developers.google.com/chrome/mobile/docs/webview/gettingstarted
The noob way to do this:

if (rs("field1")) {
do_the_stuff_a();
}
if (rs("field2")) {
do_the_stuff_b();

HTTP Basic Access Authentication
Basic Authentication uses base64 encoding(not encryption) for generating our cryptographic string which contains the information of username and password. HTTP Basic doesn’t need to be implemented over SSL, but if you don’t, it isn’t secure at all. So I’m not even going to entertain the idea of using it without.
Pros:
Cons:
In Summary – if you have control of the clients, or can ensure they use SSL, HTTP Basic is a good choice. The slowness of the SSL can be cancelled out by the speed of only making one request
Syntax of basic Authentication
Value = username:password
Encoded Value = base64(Value)
Authorization Value = Basic <Encoded Value>
//at last Authorization key/value map added to http header as follows
Authorization: <Authorization Value>
HTTP Digest Access Authentication
Digest Access Authentication uses the hashing(i.e digest means cut into small pieces) methodologies to generate the cryptographic result. HTTP Digest access authentication is a more complex form of authentication that works as follows:
Pros:
Cons:
In Summary, HTTP Digest is inherently vulnerable to at least two attacks, whereas a server using strong encryption for passwords with HTTP Basic over SSL is less likely to share these vulnerabilities.
If you don’t have control over your clients however they could attempt to perform Basic authentication without SSL, which is much less secure than Digest.
RFC 2069 Digest Access Authentication Syntax
Hash1=MD5(username:realm:password)
Hash2=MD5(method:digestURI)
response=MD5(Hash1:nonce:Hash2)
RFC 2617 Digest Access Authentication Syntax
Hash1=MD5(username:realm:password)
Hash2=MD5(method:digestURI)
response=MD5(Hash1:nonce:nonceCount:cnonce:qop:Hash2)
//some additional parameters added

The best way with the HTML you have would probably be to use the next
function, like so:
var div = $(this).next('.class2');
Since the click handler is happening to the <a>
, you could also traverse up to the parent DIV, then search down for the second DIV. You would do this with a combination of parent
and children
. This approach would be best if the HTML you put up is not exactly like that and the second DIV could be in another location relative to the link:
var div = $(this).parent().children('.class2');
If you wanted the "search" to not be limited to immediate children, you would use find
instead of children
in the example above.
Also, it is always best to prepend your class selectors with the tag name if at all possible. ie, if only <div>
tags are going to have those classes, make the selector be div.class1
, div.class2
.
In the context of db: Stored procedure is precompiled execution plan where as functions are not.

August 2018 I didn't find a working example on the iframe implementation. Other questions were related to Chrome only, which gave it away a little.
You'll have to mute sound mute=1

You can login to mysql and type

You will have all the output and you should have a better idea of what the error is.
I simply use this jQuery trick:
$("a:focus").attr('data-id');
It gets the focused a
element and gets the data-id
attribute from it.
Date argDate = new Date(); //set your date.
String argTime = "09:00"; //9 AM - 24 hour format :- Set your time.
SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy");
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MMM-yyyy HH:mm");
String dateTime = sdf.format(argDate) + " " + argTime;
Date requiredDate = dateFormat.parse(dateTime);
Your first usage of Map
is inside a function in the combat
class. That happens before Map
is defined, hence the error.
A forward declaration only says that a particular class will be defined later, so it's ok to reference it or have pointers to objects, etc. However a forward declaration does not say what members a class has, so as far as the compiler is concerned you can't use any of them until Map
is fully declared.
The solution is to follow the C++ pattern of the class declaration in a .h
file and the function bodies in a .cpp
. That way all the declarations appear before the first definitions, and the compiler knows what it's working with.
git log --grep=<pattern>
Limit the commits output to ones with log message that matches the
specified pattern (regular expression).
I would use the operator[].
map <char, int> m1;
m1['G'] ++; // If the element 'G' does not exist then it is created and
// initialized to zero. A reference to the internal value
// is returned. so that the ++ operator can be applied.
// If 'G' did not exist it now exist and is 1.
// If 'G' had a value of 'n' it now has a value of 'n+1'
So using this technique it becomes really easy to read all the character from a stream and count them:
map <char, int> m1;
std::ifstream file("Plop");
std::istreambuf_iterator<char> end;
for(std::istreambuf_iterator<char> loop(file); loop != end; ++loop)
{
++m1[*loop]; // prefer prefix increment out of habbit
}
The Request.Files collection contains any files uploaded with your form, regardless of whether they came from a FileUpload control or a manually written <input type="file">
.
So you can just write a plain old file input tag in the middle of your WebForm, and then read the file uploaded from the Request.Files collection.
You'll probably find you're setting the date to Feb 31, 2009 (if today is Jan 31) and Javascript automagically rolls that into the early part of March.
Check the day of the month, I'd expect it to be 1, 2 or 3. If it's not the same as before you added a month, roll back by one day until the month changes again.
That way, the day "last day of Jan" becomes "last day of Feb".
EDIT:
Ronald, based on your comments to other answers, you might want to steer clear of edge-case behavior such as "what happens when I try to make Feb 30" or "what happens when I try to make 2009/13/07 (yyyy/mm/dd)" (that last one might still be a problem even for my solution, so you should test it).
Instead, I would explicitly code for the possibilities. Since you don't care about the day of the month (you just want the year and month to be correct for next month), something like this should suffice:
var now = new Date();
if (now.getMonth() == 11) {
var current = new Date(now.getFullYear() + 1, 0, 1);
} else {
var current = new Date(now.getFullYear(), now.getMonth() + 1, 1);
}
That gives you Jan 1 the following year for any day in December and the first day of the following month for any other day. More code, I know, but I've long since grown tired of coding tricks for efficiency, preferring readability unless there's a clear requirement to do otherwise.

In cases where the private method is not void and the return value is used as a parameter to an external dependency's method, you can mock the dependency and use an ArgumentCaptor
to capture the return value.
For example:
ArgumentCaptor<ByteArrayOutputStream> csvOutputCaptor = ArgumentCaptor.forClass(ByteArrayOutputStream.class);
//Do your thing..
verify(this.awsService).uploadFile(csvOutputCaptor.capture());
....
assertEquals(csvOutputCaptor.getValue().toString(), "blabla");
I case you are running SpringBoot:
I just had the same problem, that I could not Autowire one of my services from the static main method.
See below an approach in case you are relying on SpringApplication.run:
@SpringBootApplication
public class PricingOnlineApplication {
@Autowired
OrchestratorService orchestratorService;
public static void main(String[] args) {
ConfigurableApplicationContext context = SpringApplication.run(PricingOnlineApplication.class, args);
PricingOnlineApplication application = context.getBean(PricingOnlineApplication.class);
application.start();
}
private void start() {
orchestratorService.performPricingRequest(null);
}
}
I noticed that SpringApplication.run returns a context which can be used similar to the above described approaches. From there, it is exactly the same as above ;-)
if using xampp, you will notice the php.ini file has twice mentioned short_open_tag . Enable the second one to short_open_tag = On . The first one is commented out and you might be tempted to uncomment and edit it but it is over-ridden by a second short_open_tag
For example, your remote host is example.com and remote login name is user1:
scp [email protected]:/path/to/file /path/to/store/file
I tend to use the following pattern to check for the document to complete loading. The function returns a Promise (if you need to support IE, include the polyfill) that resolves once the document completes loading. It uses setInterval
underneath because a similar implementation with setTimeout
could result in a very deep stack.
function getDocReadyPromise()
{
function promiseDocReady(resolve)
{
function checkDocReady()
{
if (document.readyState === "complete")
{
clearInterval(intervalDocReady);
resolve();
}
}
var intervalDocReady = setInterval(checkDocReady, 10);
}
return new Promise(promiseDocReady);
}
Of course, if you don't have to support IE:
const getDocReadyPromise = () =>
{
const promiseDocReady = (resolve) =>
{
const checkDocReady = () =>
((document.readyState === "complete") && (clearInterval(intervalDocReady) || resolve()));
let intervalDocReady = setInterval(checkDocReady, 10);
}
return new Promise(promiseDocReady);
}
With that function, you can do the following:
getDocReadyPromise().then(whatIveBeenWaitingToDo);
You can use Load function

Most simple way is to use boost::lexical_cast:
double value;
try
{
value = boost::lexical_cast<double>(my_string);
}
catch (boost::bad_lexical_cast const&)
{
value = 0;
}
span {display:block;}
also adds a line-break.
To avoid that, use span {display:inline-block;}
and then you can add width and height to the inline element, and you can align it within the block as well:
span {
display:inline-block;
width: 5em;
font-weight: normal;
text-align: center
}

Languages that use binary floating point representations (Python is one) cannot represent all fractional values exactly. If the result of your calculation is 250.99999999999 (and it might be), then taking the integer part will result in 250.

Instead of using the command line to do
copy /b 1.mp3+2.mp3 3.mp3
you could instead use "The Rename" to rename all the MP3 fragments into a series of names that are in order based on some kind of counter. Then you could just use the same command line format but change it a little to:
copy /b *.mp3 output_name.mp3
That is assuming you ripped all of these fragment MP3's at the same time and they have the same audio settings. Worked great for me when I was converting an Audio book I had in .aa to a single .mp3. I had to burn all the .aa files to 9 CD's then rip all 9 CD's and then I was left with about 90 mp3's. Really a pain in the a55.
Following on from LES2's answer, you can eliminate some repetition in the efficient version, by calling the overloaded function:
public static <T> T coalesce(T a, T b) {
return a != null ? a : b;
}
public static <T> T coalesce(T a, T b, T c) {
return a != null ? a : coalesce(b,c);
}
public static <T> T coalesce(T a, T b, T c, T d) {
return a != null ? a : coalesce(b,c,d);
}
public static <T> T coalesce(T a, T b, T c, T d, T e) {
return a != null ? a : coalesce(b,c,d,e);
}

When you look up your php-fpm.conf
example location:
cat /usr/src/php/sapi/fpm/php-fpm.conf
you will see, that you need to configure the PHP FastCGI Process Manager to actually use Unix sockets. Per default, the listen
directive` is set up to listen on a TCP socket on one port. If there's no Unix socket defined, you won't find a Unix socket file.
; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific IPv4 address on
; a specific port;
; '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
; a specific port;
; 'port' - to listen on a TCP socket to all IPv4 addresses on a

I find this quite tricky, but there is some information on it here at the MatPlotLib FAQ. It is rather cumbersome, and requires finding out about what space individual elements (ticklabels) take up...
Update:
The page states that the tight_layout()
function is the easiest way to go, which attempts to automatically correct spacing.
Otherwise, it shows ways to acquire the sizes of various elements (eg. labels) so you can then correct the spacings/positions of your axes elements. Here is an example from the above FAQ page, which determines the width of a very wide y-axis label, and adjusts the axis width accordingly:
import matplotlib.pyplot as plt
import matplotlib.transforms as mtransforms
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(range(10))
ax.set_yticks((2,5,7))
labels = ax.set_yticklabels(('really, really, really', 'long', 'labels'))
def on_draw(event):
bboxes = []
for label in labels:
bbox = label.get_window_extent()
# the figure transform goes from relative coords->pixels and we
# want the inverse of that
bboxi = bbox.inverse_transformed(fig.transFigure)
bboxes.append(bboxi)
# this is the bbox that bounds all the bboxes, again in relative
# figure coords
bbox = mtransforms.Bbox.union(bboxes)
if fig.subplotpars.left < bbox.width:
# we need to move it over
fig.subplots_adjust(left=1.1*bbox.width) # pad a little
fig.canvas.draw()
return False
fig.canvas.mpl_connect('draw_event', on_draw)
plt.show()
if you make constructor asynchronous, after creating an object, you may fall into problems like null values instead of instance objects. For instance;
MyClass instance = new MyClass();
instance.Foo(); // null exception here
That's why they don't allow this i guess.
Git has two types of branches: local
and remote
. To use git pull
and git push
as you'd like, you have to tell your local branch (my_test
) which remote branch it's tracking. In typical Git fashion this can be done in both the config file and with commands.
Commands
Make sure you're on your master
branch with
1)git checkout master
then create the new branch with
2)git branch --track my_test origin/my_test
and check it out with
3)git checkout my_test
.
You can then push
and pull
without specifying which local and remote.
However if you've already created the branch then you can use the -u
switch to tell git's push
and pull
you'd like to use the specified local and remote branches from now on, like so:
git pull -u my_test origin/my_test
git push -u my_test origin/my_test
Config
The commands to setup remote branch tracking are fairly straight forward but I'm listing the config way as well as I find it easier if I'm setting up a bunch of tracking branches. Using your favourite editor open up your project's .git/config
and add the following to the bottom.
[remote "origin"]
url = [email protected]:username/repo.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "my_test"]
remote = origin
merge = refs/heads/my_test
This specifies a remote called origin
, in this case a GitHub style one, and then tells the branch my_test
to use it as it's remote.
You can find something very similar to this in the config after running the commands above.
Some useful resources:
You could also use the IIS Manager to edit those settings.
Care of this Learn IIS article:
Using the Feature Delegation from the root of IIS:
You can then control each of machine-level read/write permissions, which will otherwise give you the overrideMode="Deny" errors.
Building on the other answers, I wanted to share an example of using the while loop construct to achieve a do-while behaviour. By using a simple boolean variable in the while condition (initialized to TRUE), and then checking our actual condition later in the if statement. One could also use a break keyword instead of the continue <- FALSE inside the if statement (probably more efficient).
df <- data.frame(X=c(), R=c())
x <- x0
continue <- TRUE
while(continue)
{
xi <- (11 * x) %% 16
df <- rbind(df, data.frame(X=x, R=xi))
x <- xi
if(xi == x0)
{
continue <- FALSE
}
}
Look at Compare-Object
Compare-Object $a1 $b1 | ForEach-Object { $_.InputObject }
Or if you would like to know where the object belongs to, then look at SideIndicator:
$a1=@(1,2,3,4,5,8)
$b1=@(1,2,3,4,5,6)
Compare-Object $a1 $b1
You can do this with this code also.

After some years with node, I can say that there are no conventions for the directory/file structure. However most (professional) express applications use a setup like:
/
/bin - scripts, helpers, binaries
/lib - your application
/config - your configuration
/public - your public files
/test - your tests
An example which uses this setup is nodejs-starter.
I personally changed this setup to:
/
/etc - contains configuration
/app - front-end javascript files
/config - loads config
/models - loads models
/bin - helper scripts
/lib - back-end express files
/config - loads config to app.settings
/models - loads mongoose models
/routes - sets up app.get('..')...
/srv - contains public files
/usr - contains templates
/test - contains test files
In my opinion, the latter matches better with the Unix-style directory structure (whereas the former mixes this up a bit).
I also like this pattern to separate files:
lib/index.js
var http = require('http');
var express = require('express');
var app = express();
app.server = http.createServer(app);
require('./config')(app);
require('./models')(app);
require('./routes')(app);
app.server.listen(app.settings.port);
module.exports = app;
lib/static/index.js
var express = require('express');
module.exports = function(app) {
app.use(express.static(app.settings.static.path));
};
This allows decoupling neatly all source code without having to bother dependencies. A really good solution for fighting nasty Javascript. A real-world example is nearby which uses this setup.
Update (filenames):
Regarding filenames most common are short, lowercase filenames. If your file can only be described with two words most JavaScript projects use an underscore as the delimiter.
Update (variables):
Regarding variables, the same "rules" apply as for filenames. Prototypes or classes, however, should use camelCase.
Update (styleguides):
This example from Java Doc helped me understand the concepts clearly:
class Driver { // ...
void main() throws InterruptedException {
CountDownLatch startSignal = new CountDownLatch(1);
CountDownLatch doneSignal = new CountDownLatch(N);
for (int i = 0; i < N; ++i) // create and start threads
new Thread(new Worker(startSignal, doneSignal)).start();
doSomethingElse(); // don't let run yet
startSignal.countDown(); // let all threads proceed
doSomethingElse();
doneSignal.await(); // wait for all to finish
}
}
class Worker implements Runnable {
private final CountDownLatch startSignal;
private final CountDownLatch doneSignal;
Worker(CountDownLatch startSignal, CountDownLatch doneSignal) {
this.startSignal = startSignal;
this.doneSignal = doneSignal;
}
public void run() {
try {
startSignal.await();
doWork();
doneSignal.countDown();
} catch (InterruptedException ex) {} // return;
}
void doWork() { ... }
}
Visual interpretation:
Evidently, CountDownLatch
allows one thread (here Driver
) to wait until a bunch of running threads (here Worker
) are done with their execution.
Nothing. The sole difference between the types is their size (and, hence, the range of values they can represent).
@Matthew's solution is the simplest and will perform well enough in most cases.
If you need high performance, AtomicInteger is a better solution ala @BalusC.
However, a faster solution (provided thread safety is not an issue) is to use TObjectIntHashMap which provides a increment(key) method and uses primitives and less objects than creating AtomicIntegers. e.g.
TObjectIntHashMap<String> map = new TObjectIntHashMap<String>()
map.increment("aaa");
cv2.circle
and cv2.lines

Format won't be completely the same, but it does write the data to a text file, and R will be able to reread it using dget
when you want to retrieve it again as a list.

Don't use enums. Reason #78 to not use enums. :) Use integers, which can easily be remoted through Bundle and Parcelable.
There is another explanation from the real world:
A book belongs to an owner, and an owner can own multiple books. But, the book can exist also without the owner, and ownership of it can change from one owner to another. The relationship between a book and an owner is a non-identifying relationship.
A book, however, is written by an author, and the author could have written multiple books. But, the book needs to be written by an author - it cannot exist without an author. Therefore, the relationship between the book and the author is an identifying relationship.
Use df.schema.names
:

df = spark.createDataFrame([("foo", 1), ("bar", 2)])
df.show()

# +---+---+
# |foo| 1|
# |bar| 2|
# +---+---+
df.schema.names
# ['_1', '_2']
for i in df.schema.names:
# df_new = df.withColumn(i, [do-something])
print i
# _1
# _2

This is not shorter, but it deals with detached branches as well:
git branch | awk -v FS=' ' '/\*/{print $NF}' | sed 's|[()]||g'
The reason why it is throwing the error is the object is disposed and after that we are trying to access the table values through the object, but object is disposed.Better to convert that into ToList() so that we can have values
Maybe it isn't actually getting the data until you use it (it is lazy loading), so dataContext doesn't exist when you are trying to do the work. I bet if you did the ToList() in scope it would be ok.
try
{
IQueryable<User> users;
var ret = null;
using (var dataContext = new dataContext())
{
users = dataContext.Users.Where(x => x.AccountID == accountId && x.IsAdmin == false);
if(users.Any())
{
ret = users.Select(x => x.ToInfo()).ToList();
}
}
Return ret;

As I posted on http://thinkinginsoftware.blogspot.com/2017/12/correctly-generate-csv-that-excel-can.html:
Tell the software developer in charge of generating the CSV to correct it. As a quick workaround you can use gsed to insert the UTF-8 BOM at the beginning of the string:
gsed -i '1s/^\(\xef\xbb\xbf\)\?/\xef\xbb\xbf/' file.csv
This command inserts the UTF-4 BOM if not present. Therefore it is an idempotent command. Now you should be able to double click the file and open it in Excel.

HTML: text/html
, full-stop.
XHTML: application/xhtml+xml
, or only if following HTML compatbility guidelines, text/html
. See the W3 Media Types Note.
XML: text/xml
, application/xml
(RFC 2376).
There are also many other media types based around XML, for example application/rss+xml
or image/svg+xml
. It's a safe bet that any unrecognised but registered ending in +xml
is XML-based. See the IANA list for registered media types ending in +xml
.
(For unregistered x-
types, all bets are off, but you'd hope +xml
would be respected.)

These work great for reading left / right "n" characters from a string, but, at least with BBC BASIC, the LEFT$()
and RIGHT$()
functions allowed you to change the left / right "n" characters too...
E.g.:
10 a$="00000"
20 RIGHT$(a$,3)="ABC"
30 PRINT a$
Would produce:
00ABC
Edit : Since writing this, I've come up with my own solution...
def left(s, amount = 1, substring = ""):
if (substring == ""):
return s[:amount]
else:
if (len(substring) > amount):
substring = substring[:amount]
return substring + s[:-amount]
def right(s, amount = 1, substring = ""):
if (substring == ""):
return s[-amount:]
else:
if (len(substring) > amount):
substring = substring[:amount]
return s[:-amount] + substring
To return n characters you'd call
substring = left(string,<n>)
Where defaults to 1 if not supplied. The same is true for right()
To change the left or right n characters of a string you'd call
newstring = left(string,<n>,substring)
This would take the first n characters of substring and overwrite the first n characters of string, returning the result in newstring. The same works for right().
For a pure cmd.exe script, you can use this piece of code that returns the current time in hundreths of seconds.
:gettime
set hh=%time:~0,2%
set mm=%time:~3,2%
set ss=%time:~6,2%
set cc=%time:~-2%
set /A %1=hh*360000+mm*6000+ss*100+cc
goto :eof
You may then use it in a wait loop like this.
:wait
call :gettime wait0
:w2
call :gettime wait1
set /A waitt = wait1-wait0
if !waitt! lss %1 goto :w2
goto :eof
And putting all pieces together:
@echo off
setlocal enableextensions enabledelayedexpansion
call :gettime t1
echo %t1%
call :wait %1
call :gettime t2
echo %t2%
set /A tt = (t2-t1)/100
echo %tt%
goto :eof
:wait
call :gettime wait0
:w2
call :gettime wait1
set /A waitt = wait1-wait0
if !waitt! lss %1 goto :w2
goto :eof
:gettime
set hh=%time:~0,2%
set mm=%time:~3,2%
set ss=%time:~6,2%
set cc=%time:~-2%
set /A %1=hh*360000+mm*6000+ss*100+cc
goto :eof

As you said, in MySQL USAGE
is synonymous with "no privileges". From the MySQL Reference Manual:
The USAGE privilege specifier stands for "no privileges." It is used at the global level with GRANT to modify account attributes such as resource limits or SSL characteristics without affecting existing account privileges.
USAGE
is a way to tell MySQL that an account exists without conferring any real privileges to that account. They merely have permission to use the MySQL server, hence USAGE
. It corresponds to a row in the `mysql`.`user`
table with no privileges set.
The IDENTIFIED BY
clause indicates that a password is set for that user. How do we know a user is who they say they are? They identify themselves by sending the correct password for their account.
A user's password is one of those global level account attributes that isn't tied to a specific database or table. It also lives in the `mysql`.`user`
table. If the user does not have any other privileges ON *.*
, they are granted USAGE ON *.*
and their password hash is displayed there. This is often a side effect of a CREATE USER
statement. When a user is created in that way, they initially have no privileges so they are merely granted USAGE
.
I like the example given by Active State using python. Here is the full link. I added the simple log in part from the link but you can get the gist of what you could do.
import telnetlib
prdLogBox='142.178.1.3'
uid = 'uid'
pwd = 'yourpassword'
tn = telnetlib.Telnet(prdLogBox)
tn.read_until("login: ")
tn.write(uid + "\n")
tn.read_until("Password:")
tn.write(pwd + "\n")
tn.write("exit\n")
tn.close()
I faced the same issue. Just download and install the SQL Server suite from the following link :http://www.microsoft.com/en-US/download/details.aspx?id=42299

Most vanilla JS Ready functions do NOT consider the scenario where the DOMContentLoaded
handler is set after the document is already loaded - Which means the function will never run. This can happen if you look for DOMContentLoaded
within an async
external script (<script async src="file.js"></script>
).
The code below checks for DOMContentLoaded
only if the document's readyState
isn't already interactive
or complete
.
var DOMReady = function(callback) {
document.readyState === "interactive" || document.readyState === "complete" ? callback() : document.addEventListener("DOMContentLoaded", callback());
};
DOMReady(function() {
//DOM ready!
});
If you want to support IE aswell:
var DOMReady = function(callback) {
if (document.readyState === "interactive" || document.readyState === "complete") {
callback();
} else if (document.addEventListener) {
document.addEventListener('DOMContentLoaded', callback());
} else if (document.attachEvent) {
document.attachEvent('onreadystatechange', function() {
if (document.readyState != 'loading') {
callback();
}
});
}
};
DOMReady(function() {
// DOM ready!
});

)
);

For Rails 4.2.1, there's this doc section:
== Transactional Migrations
If the database adapter supports DDL transactions, all migrations will automatically be wrapped in a transaction. There are queries that you can't execute inside a transaction though, and for these situations you can turn the automatic transactions off.
class ChangeEnum < ActiveRecord::Migration
disable_ddl_transaction!
def up
execute "ALTER TYPE model_size ADD VALUE 'new_value'"
end
end
You can access single characters with str.charAt(index)
or str[index]
. But the latter way is not part of ECMAScript so you better go with the former one.
Simply add git rm -r --cached <folder_name/file_name>
Sometimes, you update the .gitignore file after the commit command of files. So, the files get cached in the memory. To remove the cached files, use the above command.
This is a variant of an existing solution already provided above:
import tkinter as tk
root = tk.Tk()
root.resizable(0, 0)
root.mainloop()
The advantage is that you type less.
I use mobile-browser-emulator chrome plug-in which is has iphone device types. It actually uses user-agent and size of device on which based responsive pages are rendered
for jQuery 1.6 or higher:
if ($('input.checkbox_check').prop('checked')) {
//blah blah
}
the cross-browser-compatible way to determine if a checkbox is checked is to use the property https://api.jquery.com/prop/
Boolean types are defined in documentation:
http://docs.python.org/library/stdtypes.html#boolean-values
Quoted from doc:
Boolean values are the two constant objects False and True. They are used to represent truth values (although other values can also be considered false or true). In numeric contexts (for example when used as the argument to an arithmetic operator), they behave like the integers 0 and 1, respectively. The built-in function bool() can be used to cast any value to a Boolean, if the value can be interpreted as a truth value (see section Truth Value Testing above).
They are written as False and True, respectively.
So in java code remove braces, change true
to True
and you will be ok :)
You have to go through the collection from the last item to the first. this code is in vb

Logically, Cody's answer should work. However I don't think the command prompt handles a code block logically. For the life of me I can't get that to work properly with any more than a single command within the block. In my case, extensive testing revealed that all of the commands within the block are being cached, and executed simultaneously at the end of the block. This of course doesn't yield the expected results. Here is an oversimplified example:
if %ERRORLEVEL%==0 (
set var1=blue
set var2=cheese
set var3=%var1%_%var2%
)
This should provide var3 with the following value:
blue_cheese
but instead yields:
_
because all 3 commands are cached and executed simultaneously upon exiting the code block.
I was able to overcome this problem by re-writing the if block to only execute one command - goto - and adding a few labels. Its clunky, and I don't much like it, but at least it works.
if %ERRORLEVEL%==0 goto :error0
goto :endif
:error0
set var1=blue
set var2=cheese
set var3=%var1%_%var2%
:endif
For complete cross browser, use:

Keep in mind that if you want to keep the white spaces within a string, you may remove them unintentionally using some approaches. If you have this list
['hello world', ' ', '', 'hello'] what you may want ['hello world','hello']
first trim the list to convert any type of white space to empty string:
space_to_empty = [x.strip() for x in _text_list]
then remove empty string from them list
space_clean_list = [x for x in space_to_empty if x]

@ContextConfiguration(classes = {MyClass.class, AutowireA.class, AutowireB.class})
public class MyClassTest {
...
}
The following code works fine:
@using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
and generates as expected:
<form action="/Upload/Upload" enctype="multipart/form-data" method="post">
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
</form>
On the other hand if you are writing this code inside the context of other server side construct such as an if
or foreach
you should remove the @
before the using
. For example:
@if (SomeCondition)
{
using (Html.BeginForm("Upload", "Upload", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true)
<fieldset>
Select a file <input type="file" name="file" />
<input type="submit" value="Upload" />
</fieldset>
}
}
As far as your server side code is concerned, here's how to proceed:
[HttpPost]
public ActionResult Upload(HttpPostedFileBase file)
{
if (file != null && file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
file.SaveAs(path);
}
return RedirectToAction("Upload");
}
For someone who has the problem with populate
and also wants to do this:
clients
, users
, rooms
, messasges
.refPath
or dynamic referencepopulate
with path
and model
optionsfindOneAndReplace
/replaceOne
with $exists
CONTEXT
Goal
clients
, users
& bot
.clients
or users
with its Mongoose Models. _sender type client models is clients
, for user is users
. Message schema:
const messageSchema = new Schema({
room: {
type: Schema.Types.ObjectId,
ref: 'rooms',
required: [true, `Room's id`]
},
sender: {
_id: { type: Schema.Types.Mixed },
type: {
type: String,
enum: ['clients', 'users', 'bot'],
required: [true, 'Only 3 options: clients, users or bot.']
}
},
timetoken: {
type: String,
required: [true, 'It has to be a Nanosecond-precision UTC string']
},
data: {
lang: String,
// Format samples on https://docs.chatfuel.com/api/json-api/json-api
type: {
text: String,
quickReplies: [
{
text: String,
// Blocks' ids.
goToBlocks: [String]
}
]
}
}
mongoose.model('messages', messageSchema);
SOLUTION
My server side API request
My code
Utility function (on chatUtils.js
file) to get the type of message that you want to save:
/**
* We filter what type of message is.
*
* @param {Object} message
* @returns {string} The type of message.
*/
const getMessageType = message => {
const { type } = message.data;
const text = 'text',
quickReplies = 'quickReplies';
if (type.hasOwnProperty(text)) return text;
else if (type.hasOwnProperty(quickReplies)) return quickReplies;
};
/**
* Get the Mongoose's Model of the message's sender. We use
* the sender type to find the Model.
*
* @param {Object} message - The message contains the sender type.
*/
const getSenderModel = message => {
switch (message.sender.type) {
case 'clients':
return 'clients';
case 'users':
return 'users';
default:
return null;
}
};
module.exports = {
getMessageType,
getSenderModel
};
My server side (using Nodejs) to get the request of saving the message:
app.post('/api/rooms/:roomId/messages/new', async (req, res) => {
const { roomId } = req.params;
const { sender, timetoken, data } = req.body;
const { uuid, state } = sender;
const { type } = state;
const { lang } = data;
// For more info about message structure, look up Message Schema.
let message = {
room: new ObjectId(roomId),
sender: {
_id: type === 'bot' ? null : new ObjectId(uuid),
type
},
timetoken,
data: {
lang,
type: {}
}
};
// ==========================================
// CONVERT THE MESSAGE
// ==========================================
// Convert the request to be able to save on the database.
switch (getMessageType(req.body)) {
case 'text':
message.data.type.text = data.type.text;
break;
case 'quickReplies':
// Save every quick reply from quickReplies[].
message.data.type.quickReplies = _.map(
data.type.quickReplies,
quickReply => {
const { text, goToBlocks } = quickReply;
return {
text,
goToBlocks
};
}
);
break;
default:
break;
}
// ==========================================
// SAVE THE MESSAGE
// ==========================================
/**
* We save the message on 2 ways:
* - we replace the message type `quickReplies` (if it already exists on database) with the new one.
* - else, we save the new message.
*/
try {
const options = {
// If the quickRepy message is found, we replace the whole document.
overwrite: true,
// If the quickRepy message isn't found, we create it.
upsert: true,
// Update validators validate the update operation against the model's schema.
runValidators: true,
// Return the document already updated.
new: true
};
Message.findOneAndUpdate(
{ room: roomId, 'data.type.quickReplies': { $exists: true } },
message,
options,
async (err, newMessage) => {
if (err) {
throw Error(err);
}
// Populate the new message already saved on the database.
Message.populate(
newMessage,
{
path: 'sender._id',
model: getSenderModel(newMessage)
},
(err, populatedMessage) => {
if (err) {
throw Error(err);
}
res.send(populatedMessage);
}
);
}
);
} catch (err) {
logger.error(
`#API Error on saving a new message on the database of roomId=${roomId}. ${err}`,
{ message: req.body }
);
// Bad Request
res.status(400).send(false);
}
});
TIPs:
For the database:
refPath
, we use the util getSenderModel
that is used on populate()
. This is because of the bot. The sender.type
can be: users
with his database, clients
with his database and bot
without a database. The refPath
needs true Model reference, if not, Mongooose throw an error.sender._id
can be type ObjectId
for users and clients, or null
for the bot.For API request logic:
quickReply
message (Message DB has to have only one quickReply, but as many simple text messages as you want). We use the findOneAndUpdate
instead of replaceOne
or findOneAndReplace
.findOneAndUpdate
) and the populate
operation with the callback
of each one. This is important if you don't know if use async/await
, then()
, exec()
or callback(err, document)
. For more info look the Populate Doc.overwrite
option and without $set
query operator.upsert
option.findOneAndUpdate
and for the populate()
.populate
, we create a custom dynamic Model reference with the getSenderModel
. We can use the Mongoose dynamic reference because the sender.type
for bot
hasn't any Mongoose Model. We use a Populating Across Database with model
and path
optins.I've spend a lot of hours solving little problems here and there and I hope this will help someone!
HTTPS (HTTP over SSL) sends all HTTP content over a SSL tunel, so HTTP content and headers are encrypted as well.
I would probably build the link manually, like this:
<a href="<%=Url.Action("Subcategory", "Category", new { categoryID = parent.ID }) %>#section12">link text</a>
If you enable editing, then the edited image (as opposed to the original) will be oriented as expected:
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.allowsEditing = YES;
// set delegate and present controller
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *photo = [info valueForKey:UIImagePickerControllerEditedImage];
// do whatever
}
Enabling editing allows the user to resize and move the image before tapping "Use Photo"
It is much easier and reliable to convert html to pdf server side. We are using Google Puppeteer. It is well maintained with wrappers for any server side language of your choosing. Puppeteer uses headless Chrome to generate screenshots and/or PDF files. It will save you a LOT of headache especially if you need to generate complex PDF files with tables, images, graphs, multiple pages and so

meVeekay's answer was good and am just making it more improvised by doing 2 things.
Check whether browser supports HTML5 FileReader() or not.
Allow only image file to be upload by checking its extension.
HTML :
<div id="wrapper">
<input id="fileUpload" type="file" />
<br />
<div id="image-holder"></div>
</div>
jQuery :
$("#fileUpload").on('change', function () {
var imgPath = $(this)[0].value;
var extn = imgPath.substring(imgPath.lastIndexOf('.') + 1).toLowerCase();
if (extn == "gif" || extn == "png" || extn == "jpg" || extn == "jpeg") {
if (typeof (FileReader) != "undefined") {
var image_holder = $("#image-holder");
image_holder.empty();
var reader = new FileReader();
reader.onload = function (e) {
$("<img />", {
"src": e.target.result,
"class": "thumb-image"
}).appendTo(image_holder);
}
image_holder.show();
reader.readAsDataURL($(this)[0].files[0]);
} else {
alert("This browser does not support FileReader.");
}
} else {
alert("Pls select only images");
}
});

Increasing number of max-connections will not solve the problem.
We were experiencing the same situation on our servers. This is what happens
User open a page/view, that connect to the database, query the database, still query(queries) were not finished and user leave the page or move to some other page. So the connection that was open, will remains open, and keep increasing number of connections, if there are more users connecting with the db and doing something similar.

Which one of their Grids are you using? XtraGrid or AspXGrid? Here is a piece taken from one of my app using XtraGrid.
private void grdContactsView_RowClick(object sender, DevExpress.XtraGrid.Views.Grid.RowClickEventArgs e)
{
_selectedContact = GetSelectedRow((DevExpress.XtraGrid.Views.Grid.GridView)sender);
}
private Contact GetSelectedRow(DevExpress.XtraGrid.Views.Grid.GridView view)
{
return (Contact)view.GetRow(view.FocusedRowHandle);
}
My Grid have a list of Contact objects bound to it. Every time a row is clicked I load the selected row into _selectedContact. Hope this helps. You will find lots of information on using their controls buy visiting their support and documentation sites.

Precision is the total number of significant digits
Using CASCADE means actually telling Django to delete the referenced record. In the poll app example below: When a 'Question' gets deleted it will also delete the Choices this Question has.
e.g Question: How did you hear about us? (Choices: 1. Friends 2. TV Ad 3. Search Engine 4. Email Promotion)
When you delete this question, it will also delete all these four choices from the table. Note that which direction it flows. You don't have to put on_delete=models.CASCADE in Question Model put it in the Choice.
from django.db import models
class Question(models.Model):
question_text = models.CharField(max_length=200)
pub_date = models.dateTimeField('date_published')
class Choice(models.Model):
question = models.ForeignKey(Question, on_delete=models.CASCADE)
choice_text = models.CharField(max_legth=200)
votes = models.IntegerField(default=0)
If you don't use the STL, then the code looks a lot bit like C.
#include <cstdlib>
#include <new>
template< class T >
void append_to_array( T *&arr, size_t &n, T const &obj ) {
T *tmp = static_cast<T*>( std::realloc( arr, sizeof(T) * (n+1) ) );
if ( tmp == NULL ) throw std::bad_alloc( __FUNCTION__ );
// assign things now that there is no exception
arr = tmp;
new( &arr[ n ] ) T( obj ); // placement new
++ n;
}
T
can be any POD type, including pointers.
Note that arr
must be allocated by malloc
, not new[]
.

On ubuntu you can add this PPA Repository and use it to install python 3.7: https://launchpad.net/~jonathonf/+archive/ubuntu/python-3.7
Or a different PPA that provides several Python versions is Deadsnakes: https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa
See also here: https://askubuntu.com/questions/865554/how-do-i-install-python-3-6-using-apt-get (I know it says 3.6 in the url, but the deadsnakes ppa also contains 3.7 so you can use it for 3.7 just the same)
If you want "official" you'd have to install it from the sources from the site, get the code (which you already downloaded) and do this:
tar -xf Python-3.7.0.tar.xz
cd Python-3.7.0
./configure
make
sudo make install <-- sudo is required.
This might take a while
Python lists have the index()
method, which you can use to find the position of the first occurrence of an item in a list. Note that list.index()
raises ValueError
when the item is not present in the list, so you may need to wrap it in try
/except
:
try:
idx = lst.index(value)
except ValueError:
idx = None
To find the position of the last occurrence of an item in a list efficiently (i.e. without creating a reversed intermediate list) you can use this function:
def rindex(lst, value):
for i, v in enumerate(reversed(lst)):
if v == value:
return len(lst) - i - 1 # return the index in the original list
return None
print(rindex([1, 2, 3], 3)) # 2
print(rindex([3, 2, 1, 3], 3)) # 3
print(rindex([3, 2, 1, 3], 4)) # None
If the above issue occurs in Windows 7 or 10 based OS, the problem occurs because Tomcat is running as Windows Service. To stop Tomcat running as Windows Services, Open Windows Control Panel. Find the service "Apache Tomcat" and Stop it. The Another way is to kill the process running on port 8080 using cmd.
Open cmd running it as administrator.

Everything is mirrored on omapzoom.org. Some of the code is also mirrored on github.
Contacts is here for example.
Since December 2019, you can use the new official public code search tool for AOSP: cs.android.com. There's also the Android official source browser (based on Gitiles) has a web view of many of the different parts that make up android. Some of the projects (such as Kernel) have been removed and it now only points you to clonable git repositories.
To get all the code locally, you can use the repo helper program, or you can just clone individual repositories.
And others:
Just for the record, I got borders in the table and to get rid of it I needed to set following properties in the GridView:
GridLines="None"
CellSpacing="-1"
if ( ! $("input").is(':checked') )
Doesn't work?
You might also try iterating over the elements like so:
var iz_checked = true;
$('input').each(function(){
iz_checked = iz_checked && $(this).is(':checked');
});
if ( ! iz_checked )
The DOMContentLoaded
event will fire as soon as the DOM hierarchy has been fully constructed, the load
event will do it when all the images and sub-frames have finished loading.
DOMContentLoaded
will work on most modern browsers, but not on IE including IE9 and above. There are some workarounds to mimic this event on older versions of IE, like the used on the jQuery library, they attach the IE specific onreadystatechange
event.
0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.
There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.
I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException
and Application.ThreadException
, as appropriate.
You have not defined the variable input_line
.
Add this:
string input_line;
And add this include.
#include <string>
Here is the full example. I also removed the semi-colon after the while loop, and you should have getline
inside the while to properly detect the end of the stream.
#include <iostream>
#include <string>
int main() {
for (std::string line; std::getline(std::cin, line);) {
std::cout << line << std::endl;
}
return 0;
}
Environment variables must be strings, so use
os.environ["DEBUSSY"] = "1"
to set the variable DEBUSSY
to the string 1
.
To access this variable later, simply use:
print(os.environ["DEBUSSY"])
Child processes automatically inherit the environment variables of the parent process -- no special action on your part is required.
PYTHONPATH
is an environment variable those content is added to the sys.path
where Python looks for modules. You can set it to whatever you like.
However, do not mess with PYTHONPATH
. More often than not, you are doing it wrong and it will only bring you trouble in the long run. For example, virtual environments could do strange things…
I would suggest you learned how to package a Python module properly, maybe using this easy setup. If you are especially lazy, you could use cookiecutter to do all the hard work for you.

What are you trying to do?
The InterruptedException
is thrown when a thread is waiting or sleeping and another thread interrupts it using the interrupt
method in class Thread
. So if you catch this exception, it means that the thread has been interrupted. Usually there is no point in calling Thread.currentThread().interrupt();
again, unless you want to check the "interrupted" status of the thread from somewhere else.
Regarding your other option of throwing a RuntimeException
, it does not seem a very wise thing to do (who will catch this? how will it be handled?) but it is difficult to tell more without additional information.
Options to remove duplicates may include the following generic data structures:
Here is a summary on quickly getting either one in Python.
Given
from collections import OrderedDict
seq = [u"nowplaying", u"PBS", u"PBS", u"nowplaying", u"job", u"debate", u"thenandnow"]
Code
Option 1 - A set (unordered):
list(set(seq))
# ['thenandnow', 'PBS', 'debate', 'job', 'nowplaying']
Option 2 - Python doesn't have ordered sets, but here are some ways to mimic one (insertion ordered):
list(OrderedDict.fromkeys(seq))
# ['nowplaying', 'PBS', 'job', 'debate', 'thenandnow']
list(dict.fromkeys(seq)) # py36
# ['nowplaying', 'PBS', 'job', 'debate', 'thenandnow']
The last option is recommended if using Python 3.6+. See more details in this post.
Note: listed elements must be hashable. See details on the latter example in this blog post. Furthermore, see R. Hettinger's post on the same technique; the order preserving dict is extended from one of his early implementations. See also more on total ordering.

Import gives you access to other modules in your program. You can't decide to import a text file. If you want to read from a file that's in the same directory, you can look at this. Here's another StackOverflow post about it.
i guess you mean System Programs and Application programs
System Programs makes the hardware run , Applications are for specific tasks
an Example for System Programs are Device Drivers
as for the Applications you can say web browsers , word porcessros etc
I created a class structure for collections in general that would meet this requirement. and it looks like this:
class Collection {
constructor() {
this.collection = [];
this.index = 0;
}
log() {
return console.log(this.collection);
}
push(value) {
return this.collection.push(value);
}
pushAll(...values) {
return this.collection.push(...values);
}
pop() {
return this.collection.pop();
}
shift() {
return this.collection.shift();
}
unshift(value) {
return this.collection.unshift(value);
}
unshiftAll(...values) {
return this.collection.unshift(...values);
}
remove(index) {
return this.collection.splice(index, 1);
}
add(index, value) {
return this.collection.splice(index, 0, value);
}
replace(index, value) {
return this.collection.splice(index, 1, value);
}
clear() {
this.collection.length = 0;
}
isEmpty() {
return this.collection.length === 0;
}
viewFirst() {
return this.collection[0];
}
viewLast() {
return this.collection[this.collection.length - 1];
}
current(){
if((this.index <= this.collection.length - 1) && (this.index >= 0)){
return this.collection[this.index];
}
else{
return `Object index exceeds collection range.`;
}
}
next() {
this.index++;
this.index > this.collection.length - 1 ? this.index = 0 : this.index;
return this.collection[this.index];
}
previous(){
this.index--;
this.index < 0 ? (this.index = this.collection.length-1) : this.index;
return this.collection[this.index];
}
}
...and essentially what you would do is have a collection of arrays of whatever length for your pages pushed into the class object, and then use the next() and previous() functions to display whatever 'page' (index) you wanted to display. Would essentially look like this:
let books = new Collection();
let firstPage - [['dummyData'], ['dummyData'], ['dummyData'], ['dummyData'], ['dummyData'],];
let secondPage - [['dumberData'], ['dumberData'], ['dumberData'], ['dumberData'], ['dumberData'],];
books.pushAll(firstPage, secondPage); // loads each array individually
books.current() // display firstPage
books.next() // display secondPage
Boost provides a string algorithm for this:
#include <boost/algorithm/string.hpp>
std::string str = "HELLO, WORLD!";
boost::algorithm::to_lower(str); // modifies str

const std::string str = "HELLO, WORLD!";
const std::string lower_str = boost::algorithm::to_lower_copy(str);
Why don't you just save/serve the CSS file as UTF-8?
nav a:hover:after {
content: "?";
}
If that's not good enough, and you want to keep it all-ASCII:
nav a:hover:after {
content: "\2193";
}
The general format for a Unicode character inside a string is \000000
to \FFFFFF
– a backslash followed by six hexadecimal digits. You can leave out leading 0
digits when the Unicode character is the last character in the string or when you add a space after the Unicode character. See the spec below for full details.
Relevant part of the CSS2 spec:
Third, backslash escapes allow authors to refer to characters they cannot easily put in a document. In this case, the backslash is followed by at most six hexadecimal digits (0..9A..F), which stand for the ISO 10646 ([ISO10646]) character with that number, which must not be zero. (It is undefined in CSS 2.1 what happens if a style sheet does contain a character with Unicode codepoint zero.) If a character in the range [0-9a-fA-F] follows the hexadecimal number, the end of the number needs to be made clear. There are two ways to do that:
- with a space (or other white space character): "\26 B" ("&B"). In this case, user agents should treat a "CR/LF" pair (U+000D/U+000A) as a single white space character.
- by providing exactly 6 hexadecimal digits: "\000026B" ("&B")
In fact, these two methods may be combined. Only one white space character is ignored after a hexadecimal escape. Note that this means that a "real" space after the escape sequence must be doubled.
If the number is outside the range allowed by Unicode (e.g., "\110000" is above the maximum 10FFFF allowed in current Unicode), the UA may replace the escape with the "replacement character" (U+FFFD). If the character is to be displayed, the UA should show a visible symbol, such as a "missing character" glyph (cf. 15.2, point 5).
- Note: Backslash escapes are always considered to be part of an identifier or a string (i.e., "\7B" is not punctuation, even though "{" is, and "\32" is allowed at the start of a class name, even though "2" is not).

}
stage('Build') {
**dir('project-dir') {**

I was having similar issue and adding
sessionFactory.setAnnotatedClasses(User.class);
this line helped but before that I was having
sessionFactory.setPackagesToScan(new String[] { "com.rg.spring.model" });

I don't think there is a way to ignore adding DEFINER
s to the dump. But there are ways to remove them after the dump file is created.
Open the dump file in a text editor and replace all occurrences of DEFINER=root@localhost
with an empty string ""
Edit the dump (or pipe the output) using perl
:
perl -p -i.bak -e "s/DEFINER=\`\w.*\`@\`\d[0-3].*[0-3]\`//g" mydatabase.sql
mysqldump ... | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > triggers_backup.sql
