The clean way to use mbstowcs
is to call it twice to find the length of the result:
const char * cs = <your input char*>
size_t wn = mbsrtowcs(NULL, &cs, 0, NULL);
// error if wn == size_t(-1)
wchar_t * buf = new wchar_t[wn + 1](); // value-initialize to 0 (see below)
wn = mbsrtowcs(buf, &cs, wn + 1, NULL);
// error if wn == size_t(-1)
assert(cs == NULL); // successful conversion
// result now in buf, return e.g. as std::wstring
delete[] buf;
Don't forget to call setlocale(LC_CTYPE, "");
at the beginning of your program!
The advantage over the Windows MultiByteToWideChar
is that this is entirely standard C, although on Windows you might prefer the Windows API function anyway.
I usually wrap this method, along with the opposite one, in two conversion functions string
->wstring
and wstring
->string
. If you also add trivial overloads string
->string
and wstring
->wstring
, you can easily write code that compiles with the Winapi TCHAR
typedef in any setting.
[Edit:] I added zero-initialization to buf
, in case you plan to use the C array directly. I would usually return the result as std::wstring(buf, wn)
, though, but do beware if you plan on using C-style null-terminated arrays.[/]
In a multithreaded environment you should pass a thread-local conversion state to the function as its final (currently invisible) parameter.
Here is a small rant of mine on this topic.
Simply pass the BSTR directly to the wstring constructor, it is compatible with a wchar_t*:
BSTR btest = SysAllocString(L"Test");
assert(btest != NULL);
std::wstring wtest(btest);
assert(0 == wcscmp(wtest.c_str(), btest));
Converting BSTR to std::string requires a conversion to char* first. That's lossy since BSTR stores a utf-16 encoded Unicode string. Unless you want to encode in utf-8. You'll find helper methods to do this, as well as manipulate the resulting string, in the ICU library.
I had a similarly strange problem with a file from the program e-prime (edat -> SPSS conversion), but then I discovered that there are many additional encodings you can use. this did the trick for me:
tbl <- read.delim("dir/file.txt", fileEncoding="UCS-2LE")
There's probably a more direct way using regular expressions. With luck, somebody else will provide it. But here's what I'd do without needing to go to the manuals.
Create a PLSQL function to receive your input string and return a varchar2.
In the PLSQL function, do an asciistr() of your input. The PLSQL is because that may return a string longer than 4000 and you have 32K available for varchar2 in PLSQL.
That function converts the non-ASCII characters to \xxxx notation. So you can use regular expressions to find and remove those. Then return the result.
None of these answers solved the problem for me. The root cause being:
You cannot store 4-byte characters in MySQL with the utf-8 character set.
MySQL has a 3 byte limit on utf-8 characters (yes, it's wack, nicely summed up by a Django developer here)
To solve this you need to:
settings.py
DATABASES = {
'default': {
'ENGINE':'django.db.backends.mysql',
...
'OPTIONS': {'charset': 'utf8mb4'},
}
}
Note: When recreating your database you may run into the 'Specified key was too long' issue.
The most likely cause is a CharField
which has a max_length of 255 and some kind of index on it (e.g. unique). Because utf8mb4 uses 33% more space than utf-8 you'll need to make these fields 33% smaller.
In this case, change the max_length from 255 to 191.
Alternatively you can edit your MySQL configuration to remove this restriction but not without some django hackery
UPDATE: I just ran into this issue again and ended up switching to PostgreSQL because I was unable to reduce my VARCHAR
to 191 characters.
Check the LOB segment name from dba_lobs using the table name.
select TABLE_NAME,OWNER,COLUMN_NAME,SEGMENT_NAME from dba_lobs where TABLE_NAME='<<TABLE NAME>>';
Now use the segment name to find the bytes used in dba_segments.
select s.segment_name, s.partition_name, bytes/1048576 "Size (MB)"
from dba_segments s, dba_lobs l
where s.segment_name = l.segment_name
and s.owner = '<< OWNER >> ' order by s.segment_name, s.partition_name;
Have you tried adding a magic comment in the script where you use non-ASCII chars? It should go on top of the script.
#!/bin/env ruby
# encoding: utf-8
It worked for me like a charm.
You use the lpMultiByteStr [out] parameter by creating a new char array. You then pass this char array in to get it filled. You only need to initialize the length of the string + 1 so that you can have a null terminated string after the conversion.
Here are a couple of useful helper functions for you, they show the usage of all parameters.
#include <string>
std::string wstrtostr(const std::wstring &wstr)
{
// Convert a Unicode string to an ASCII string
std::string strTo;
char *szTo = new char[wstr.length() + 1];
szTo[wstr.size()] = '\0';
WideCharToMultiByte(CP_ACP, 0, wstr.c_str(), -1, szTo, (int)wstr.length(), NULL, NULL);
strTo = szTo;
delete[] szTo;
return strTo;
}
std::wstring strtowstr(const std::string &str)
{
// Convert an ASCII string to a Unicode String
std::wstring wstrTo;
wchar_t *wszTo = new wchar_t[str.length() + 1];
wszTo[str.size()] = L'\0';
MultiByteToWideChar(CP_ACP, 0, str.c_str(), -1, wszTo, (int)str.length());
wstrTo = wszTo;
delete[] wszTo;
return wstrTo;
}

Anytime in documentation when you see that it has a parameter which is a pointer to a type, and they tell you it is an out variable, you will want to create that type, and then pass in a pointer to it. The function will use that pointer to fill your variable.
So you can understand this better:
//pX is an out parameter, it fills your variable with 10.
void fillXWith10(int *pX)
{
*pX = 10;
}
int main(int argc, char ** argv)
{
int X;
fillXWith10(&X);
return 0;
}
My two cents
Indexes can fail when not using the correct datatypes:
In SQL Server: When you have an index over a VARCHAR column and present it a Unicode String, SQL Server does not make use of the index. The same thing happens when you present a BigInt to a indexed-column containing SmallInt. Even if the BigInt is small enough to be a SmallInt, SQL Server is not able to use the index. The other way around you do not have this problem (when providing SmallInt or Ansi-Code to an indexed BigInt ot NVARCHAR column).
Datatypes can vary between different DBMS's (DataBase Management System):
Know that every database has slightly different datatypes and VARCHAR does not means the same everywhere. While SQL Server has VARCHAR and NVARCHAR, an Apache/Derby database has only VARCHAR and there VARCHAR is in Unicode.
I have my web applications (PRODUCTION, STAGING, TEST) hosted on IIS web server. So it was not possible to rely on ASPNETCORE_ENVIRONMENT operative's system enviroment variable, because setting it to a specific value (for example STAGING) has effect on others applications.
As work-around, I defined a custom file (envsettings.json) within my visualstudio solution:
with following content:
{
// Possible string values reported below. When empty it use ENV variable value or Visual Studio setting.
// - Production
// - Staging
// - Test
// - Development
"ASPNETCORE_ENVIRONMENT": ""
}
Then, based on my application type (Production, Staging or Test) I set this file accordly: supposing I am deploying TEST application, i will have:
"ASPNETCORE_ENVIRONMENT": "Test"
After that, in Program.cs file just retrieve this value and then set the webHostBuilder's enviroment:
public class Program
{
public static void Main(string[] args)
{
var currentDirectoryPath = Directory.GetCurrentDirectory();
var envSettingsPath = Path.Combine(currentDirectoryPath, "envsettings.json");
var envSettings = JObject.Parse(File.ReadAllText(envSettingsPath));
var enviromentValue = envSettings["ASPNETCORE_ENVIRONMENT"].ToString();
var webHostBuilder = new WebHostBuilder()
.UseKestrel()
.CaptureStartupErrors(true)
.UseSetting("detailedErrors", "true")
.UseContentRoot(currentDirectoryPath)
.UseIISIntegration()
.UseStartup<Startup>();
// If none is set it use Operative System hosting enviroment
if (!string.IsNullOrWhiteSpace(enviromentValue))
{
webHostBuilder.UseEnvironment(enviromentValue);
}
var host = webHostBuilder.Build();
host.Run();
}
}
Remember to include the envsettings.json in the publishOptions (project.json):
"publishOptions":
{
"include":
[
"wwwroot",
"Views",
"Areas/**/Views",
"envsettings.json",
"appsettings.json",
"appsettings*.json",
"web.config"
]
},
This solution make me free to have ASP.NET CORE application hosted on same IIS, independently from envoroment variable value.
if( char.toUpperCase() != char.toLowerCase() )
Will return true only in case of letter
As point out in below comment, if your character is non English, High Ascii or double byte range then you need to add check for code point.
if( char.toUpperCase() != char.toLowerCase() || char.codePointAt(0) > 127 )

In Visual Studio, you can't just open a .cpp
file and expect it to run. You must create a project first, or open the .cpp in some existing project.
In your case, there is no project, so there is no project to build.
Go to File --> New --> Project --> Visual C++ --> Win32 Console Application
. You can uncheck "create a directory for solution". On the next page, be sure to check "Empty project".
Then, You can add .cpp
files you created outside the Visual Studio by right clicking in the Solution explorer
on folder icon "Source" and Add->Existing Item.
Obviously You can create new .cpp this way too (Add --> New). The .cpp file will be created in your project directory.
Then you can press ctrl+F5 to compile without debugging and can see output on console window.

As you have already stated in your question you have more than one option. A very basic approach would be using the tag referencing your PHP file in the method attribute. However as esoteric as it may sound AJAX is a more complete approach. Considering that an AJAX call (in combination with jQuery) can be as simple as:
$.post("yourfile.php", {data : "This can be as long as you want"});
And you get a more flexible solution, for example triggering a function after the server request is completed. Hope this helps.

The answer your question: the correct way to refer to a different sheet is by appropriately qualifying each Range
you use.
Please read this explanation and its conclusion, which I guess will give essential information.
The error you are getting is likely due to the sought-for value Sheet2!D2
not being found in the searched range Sheet1!A1:A65536
. This may stem from two cases:
The value is actually not present (pointed out by chris nielsen).
You are searching the wrong Range. If the ActiveSheet
is Sheet1
, then using Range("D2")
without qualifying it will be searching for Sheet1!D2
, and it will throw the same error even if the sought-for value is present in the correct Range.
Code accounting for this (and items below) follows:
Sub srch()
Dim ws1 As Worksheet, ws2 As Worksheet
Dim srchres As Variant
Set ws1 = Worksheets("Sheet1")
Set ws2 = Worksheets("Sheet2")
On Error Resume Next
srchres = Application.WorksheetFunction.VLookup(ws2.Range("D2"), ws1.Range("A1:C65536"), 1, False)
On Error GoTo 0
If (IsEmpty(srchres)) Then
ws2.Range("E2").Formula = CVErr(xlErrNA) ' Use whatever you want
Else
ws2.Range("E2").Value = srchres
End If
End Sub
I will point out a few additional notable points:
Catching the error as done by chris nielsen is a good practice, probably mandatory if using Application.WorksheetFunction.VLookup
(although it will not suitably handle case 2 above).
This catching is actually performed by the function VLOOKUP
as entered in a cell (and, if the sought-for value is not found, the result of the error is presented as #N/A
in the result). That is why the first soluton by L42 does not need any extra error handling (it is taken care by =VLOOKUP...
).
Using =VLOOKUP...
is fundamentally different from Application.WorksheetFunction.VLookup
: the first leaves a formula, whose result may change if the cells referenced change; the second writes a fixed value.
Both solutions by L42 qualify Ranges suitably.
You are searching the first column of the range, and returning the value in that same column. Other functions are available for that (although yours works fine).
I took @Dmitriusan's answer and made it into an alias:
alias docker-run-prev-container='prev_container_id="$(docker ps -aq | head -n1)" && docker commit "$prev_container_id" "prev_container/$prev_container_id" && docker run -it --entrypoint=bash "prev_container/$prev_container_id"'
Add this into your ~/.bashrc
aliases file, and you'll have a nifty new docker-run-prev-container
alias which'll drop you into a shell in the previous container.

After deleting I'm also using VACUUM
command. So for full TRUNCATE
equivalent I use this code:
DELETE FROM <table>;
UPDATE SQLITE_SEQUENCE SET seq = 0 WHERE name = '<table>';
VACUUM;
Deleting isn't working for me for reset Auto Increment
DELETE FROM "sqlite_sequence" WHERE "name"='<table>';
To read more about VACUUM you can go here: https://blogs.gnome.org/jnelson/2015/01/06/sqlite-vacuum-and-auto_vacuum/
Here is a simple example to bring an overlay effect with a loading icon over another div.
<style>
#overlay {
position: absolute;
width: 100%;
height: 100%;
background: black url('icons/loading.gif') center center no-repeat; /* Make sure the path and a fine named 'loading.gif' is there */
background-size: 50px;
z-index: 1;
opacity: .6;
}
.wraper{
position: relative;
width:400px; /* Just for testing, remove width and height if you have content inside this div */
height:500px; /* Remove this if you have content inside */
}
</style>
<h2>The overlay tester</h2>
<div class="wraper">
<div id="overlay"></div>
<h3>Apply the overlay over this div</h3>
</div>

n % x == 0
Means that n can be divided by x. So... for instance, in your case:
boolean isDivisibleBy20 = number % 20 == 0;
Also, if you want to check whether a number is even or odd (whether it is divisible by 2 or not), you can use a bitwise operator:
boolean even = (number & 1) == 0;
boolean odd = (number & 1) != 0;
I changed this:
var htmlText = '<embed width=100% height=100%'
+ ' type="application/pdf"'
+ ' src="data:application/pdf,'
+ escape(pdfText)
+ '"></embed>';
to
var htmlText = '<embed width=100% height=100%'
+ ' type="application/pdf"'
+ ' src="data:application/pdf;base64,'
+ escape(pdfText)
+ '"></embed>';
and it worked for me.
You can also install Fiddler (http://www.fiddler2.com/fiddler2/) which is very easy to install (easier than Apache for example).
After launching it, it will register itself as system proxy. Then open the "Rules" menu, and choose "Customize Rules..." to open a JScript file which allow you to customize requests.
To add a custom header, just add a line in the OnBeforeRequest
function:
oSession.oRequest.headers.Add("MyHeader", "MyValue");
if (true)
{
return View();
}
else
{
return View("another view name");
}
I would try triming the number to see what you get:
select len(rtrim(ltrim(userid))) from audit
if that return the correct value then just do:
select convert(int, rtrim(ltrim(userid))) from audit
if that doesn't return the correct value then I would do a replace to remove the empty space:
select convert(int, replace(userid, char(0), '')) from audit
This task can be accomplished using one of the android's main building block named as Intents and One of the methods public void startActivity (Intent intent)
which belongs to your Activity class.
An intent is an abstract description of an operation to be performed. It can be used with startActivity to launch an Activity, broadcastIntent to send it to any interested BroadcastReceiver components, and startService(Intent) or bindService(Intent, ServiceConnection, int) to communicate with a background Service.
An Intent provides a facility for performing late runtime binding between the code in different applications. Its most significant use is in the launching of activities, where it can be thought of as the glue between activities. It is basically a passive data structure holding an abstract description of an action to be performed.
Refer the official docs -- http://developer.android.com/reference/android/content/Intent.html
public void startActivity (Intent intent)
-- Used to launch a new activity.
So suppose you have two Activity class --
PresentActivity -- This is your current activity from which you want to go the second activity.
NextActivity -- This is your next Activity on which you want to move.
So the Intent would be like this
Intent(PresentActivity.this, NextActivity.class)
Finally this will be the complete code
public class PresentActivity extends Activity {
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.content_layout_id);
final Button button = (Button) findViewById(R.id.button_id);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
Intent activityChangeIntent = new Intent(PresentActivity.this, NextActivity.class);
// currentContext.startActivity(activityChangeIntent);
PresentActivity.this.startActivity(activityChangeIntent);
}
});
}
}
I think you lack to pass Connection
object to your command
object. and it is much better if you will use command
and parameters
for that.
using (SqlConnection connection = new SqlConnection("ConnectionStringHere"))
{
using (SqlCommand command = new SqlCommand())
{
command.Connection = connection; // <== lacking
command.CommandType = CommandType.Text;
command.CommandText = "INSERT into tbl_staff (staffName, userID, idDepartment) VALUES (@staffName, @userID, @idDepart)";
command.Parameters.AddWithValue("@staffName", name);
command.Parameters.AddWithValue("@userID", userId);
command.Parameters.AddWithValue("@idDepart", idDepart);
try
{
connection.Open();
int recordsAffected = command.ExecuteNonQuery();
}
catch(SqlException)
{
// error here
}
finally
{
connection.Close();
}
}
}
Basically it contains all the attributes which describe the object in question. It can be used to alter or read the attributes.
Quoting from the documentation for __dict__
A dictionary or other mapping object used to store an object's (writable) attributes.
Remember, everything is an object in Python. When I say everything, I mean everything like functions, classes, objects etc (Ya you read it right, classes. Classes are also objects). For example:
def func():
pass
func.temp = 1
print(func.__dict__)
class TempClass:
a = 1
def temp_function(self):
pass
print(TempClass.__dict__)
will output
{'temp': 1}
{'__module__': '__main__',
'a': 1,
'temp_function': <function TempClass.temp_function at 0x10a3a2950>,
'__dict__': <attribute '__dict__' of 'TempClass' objects>,
'__weakref__': <attribute '__weakref__' of 'TempClass' objects>,
'__doc__': None}

If your data resides on HDFS, perhaps the fastest approach is to use hadoop streaming. Apache Pig's COUNT UDF, operates on a bag, and therefore uses a single reducer to compute the number of rows. Instead you can manually set the number of reducers in a simple hadoop streaming script as follows:
$HADOOP_HOME/bin/hadoop jar $HADOOP_HOME/hadoop-streaming.jar -Dmapred.reduce.tasks=100 -input <input_path> -output <output_path> -mapper /bin/cat -reducer "wc -l"
Note that I manually set the number of reducers to 100, but you can tune this parameter. Once the map-reduce job is done, the result from each reducer is stored in a separate file. The final count of rows is the sum of numbers returned by all reducers. you can get the final count of rows as follows:
$HADOOP_HOME/bin/hadoop fs -cat <output_path>/* | paste -sd+ | bc
There's more to it than this, but you're probably looking for this list:

@Robino was suggesting to add some tests which make sense, so here is a simple benchmark between 3 possible ways (maybe the most used ones) to convert an iterator to a list:
list(my_iterator)
[*my_iterator]
[e for e in my_iterator]
I have been using simple_bechmark library
from simple_benchmark import BenchmarkBuilder
from heapq import nsmallest
b = BenchmarkBuilder()
@b.add_function()
def convert_by_type_constructor(size):
list(iter(range(size)))
@b.add_function()
def convert_by_list_comprehension(size):
[e for e in iter(range(size))]
@b.add_function()
def convert_by_unpacking(size):
[*iter(range(size))]
@b.add_arguments('Convert an iterator to a list')
def argument_provider():
for exp in range(2, 22):
size = 2**exp
yield size, size
r = b.run()
r.plot()
As you can see there is very hard to make a difference between conversion by the constructor and conversion by unpacking, conversion by list comprehension is the “slowest” approach.
I have been testing also across different Python versions (3.6, 3.7, 3.8, 3.9) by using the following simple script:
import argparse
import timeit
parser = argparse.ArgumentParser(
description='Test convert iterator to list')
parser.add_argument(
'--size', help='The number of elements from iterator')
args = parser.parse_args()
size = int(args.size)
repeat_number = 10000
# do not wait too much if the size is too big
if size > 10000:
repeat_number = 100
def test_convert_by_type_constructor():
list(iter(range(size)))
def test_convert_by_list_comprehension():
[e for e in iter(range(size))]
def test_convert_by_unpacking():
[*iter(range(size))]
def get_avg_time_in_ms(func):
avg_time = timeit.timeit(func, number=repeat_number) * 1000 / repeat_number
return round(avg_time, 6)
funcs = [test_convert_by_type_constructor,
test_convert_by_unpacking, test_convert_by_list_comprehension]
print(*map(get_avg_time_in_ms, funcs))
The script will be executed via a subprocess from a Jupyter Notebook (or a script), the size parameter will be passed through command-line arguments and the script results will be taken from standard output.
from subprocess import PIPE, run
import pandas
simple_data = {'constructor': [], 'unpacking': [], 'comprehension': [],
'size': [], 'python version': []}
size_test = 100, 1000, 10_000, 100_000, 1_000_000
for version in ['3.6', '3.7', '3.8', '3.9']:
print('test for python', version)
for size in size_test:
command = [f'python{version}', 'perf_test_convert_iterator.py', f'--size={size}']
result = run(command, stdout=PIPE, stderr=PIPE, universal_newlines=True)
constructor, unpacking, comprehension = result.stdout.split()
simple_data['constructor'].append(float(constructor))
simple_data['unpacking'].append(float(unpacking))
simple_data['comprehension'].append(float(comprehension))
simple_data['python version'].append(version)
simple_data['size'].append(size)
df_ = pandas.DataFrame(simple_data)
df_
You can get my full notebook from here.
In most of the cases, in my tests, unpacking shows to be faster, but the difference is so small that the results may change from a run to the other. Again, the comprehension approach is the slowest, in fact, the other 2 methods are up to ~ 60% faster.
Yes, this is an old question. But it's misleading, as this was the first result in my search, and both the answers aren't correct anymore.
You can change your Github account name at any time.
To do this, click your profile picture > Settings

.
Links to your repositories will redirect to the new URLs, but they should be updated on other sites because someone who chooses your abandoned username can override the links. Links to your profile page will be 404'd.
For more information, see the official help page.
And furthermore, if you want to change your username to something else, but that specific username is being taken up by someone else who has been completely inactive for the entire time their account has existed, you can report their account for name squatting.
You can do this now and it doesn't require a bunch of reflection code.
import com.google.common.reflect.TypeToken;
public class Q26289147
{
public static void main(final String[] args) throws IllegalAccessException, InstantiationException
{
final StrawManParameterizedClass<String> smpc = new StrawManParameterizedClass<String>() {};
final String string = (String) smpc.type.getRawType().newInstance();
System.out.format("string = \"%s\"",string);
}
static abstract class StrawManParameterizedClass<T>
{
final TypeToken<T> type = new TypeToken<T>(getClass()) {};
}
}
Of course if you need to call the constructor that will require some reflection, but that is very well documented, this trick isn't!
Here is the JavaDoc for TypeToken.
(1) Use str.isalpha() when you print the string.
(2) Please check below program for your reference:-
str = "this"; # No space & digit in this string
print str.isalpha() # it gives return True
str = "this is 2";
print str.isalpha() # it gives return False
Note:- I checked above example in Ubuntu.
You can use serialize and base64_encode from the client side. After that, then use unserialize and base64_decode on the server side.
Like:
On the client side, use:
$postvalue = array("a", "b", "c");
$postvalue = base64_encode(serialize($array));
// Your form hidden input
<input type="hidden" name="result" value="<?php echo $postvalue; ?>">
On the server side, use:
$postvalue = unserialize(base64_decode($_POST['result']));
print_r($postvalue) // Your desired array data will be printed here

This website has some nice examples for using spring's RestTemplate. Here is a code example of how it can work to get a simple object:
private static void getEmployees()
{
final String uri = "http://localhost:8080/springrestexample/employees.xml";
RestTemplate restTemplate = new RestTemplate();
String result = restTemplate.getForObject(uri, String.class);
System.out.println(result);
}
I've found the same thing, but only on emulators that have the Use Host GPU setting ticked. Try turning that off, you'll no longer see those warnings (and the emulator will run horribly, horribly slowly..)
In my experience those warnings are harmless. Notice that the "error" is EGL_SUCCESS, which would seem to indicate no error at all!

According to their docs, the following browsers support drag & drop:
Simplest way to accomplish this task
If you want the query to be case-sensitive
db.getCollection("users").find({'username':/Son/})
If you want the query to be case-insensitive
db.getCollection("users").find({'username':/Son/i})
Here is an optimized version of npinti's answer:
import javax.swing.text.AttributeSet;
import javax.swing.text.BadLocationException;
import javax.swing.text.JTextComponent;
import javax.swing.text.PlainDocument;
import java.awt.*;
public class TextComponentLimit extends PlainDocument
{
private int charactersLimit;
private TextComponentLimit(int charactersLimit)
{
this.charactersLimit = charactersLimit;
}
@Override
public void insertString(int offset, String input, AttributeSet attributeSet) throws BadLocationException
{
if (isAllowed(input))
{
super.insertString(offset, input, attributeSet);
} else
{
Toolkit.getDefaultToolkit().beep();
}
}
private boolean isAllowed(String string)
{
return (getLength() + string.length()) <= charactersLimit;
}
public static void addTo(JTextComponent textComponent, int charactersLimit)
{
TextComponentLimit textFieldLimit = new TextComponentLimit(charactersLimit);
textComponent.setDocument(textFieldLimit);
}
}
To add a limit to your JTextComponent
, simply write the following line of code:
JTextFieldLimit.addTo(myTextField, myMaximumLength);
You can use this rewriteBatchedStatements
parameter to make the batch insert even faster.
you can read here about the param: MySQL and JDBC with rewriteBatchedStatements=true
Via powershell (file.ps1) I use the following
$username = [System.Security.Principal.WindowsIdentity]::GetCurrent().Name
It returns the name of the user in the "Domain\Username" format. If you just want the username just write
$username = [System.Security.Principal.WindowsIdentity]::GetCurrent().Name.Split("\")[1]
The advantage is that It works with windows 10 windows 8 server 2016. As far as I remember with also other OS like Win7 etc. (not older) . And yeah via batch you can simply use
$username = &whoami
You will need to use openssl.
openssl pkcs12 -export -out domain.name.pfx -inkey domain.name.key -in domain.name.crt
The key file is just a text file with your private key in it.
If you have a root CA and intermediate certs, then include them as well using multiple -in
params
openssl pkcs12 -export -out domain.name.pfx -inkey domain.name.key -in domain.name.crt -in intermediate.crt -in rootca.crt
You can install openssl from here: openssl
Aggregation implies a relationship where the child can exist independently of the parent. Example: Class (parent) and Student (child). Delete the Class and the Students still exist.
Composition implies a relationship where the child cannot exist independent of the parent. Example: House (parent) and Room (child). Rooms don't exist separate to a House.
The above two are forms of containment (hence the parent-child relationships).
Dependency is a weaker form of relationship and in code terms indicates that a class uses another by parameter or return type.
Dependency is a form of association.

var appName = System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe";
using (var Key = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true))
Key.SetValue(appName, 99999, RegistryValueKind.DWord);
According to what I read here (Controlling WebBrowser Control Compatibility:
What Happens if I Set the FEATURE_BROWSER_EMULATION Document Mode Value Higher than the IE Version on the Client?
Obviously, the browser control can only support a document mode that is less than or equal to the IE version installed on the client. Using the FEATURE_BROWSER_EMULATION key works best for enterprise line of business apps where there is a deployed and support version of the browser. In the case you set the value to a browser mode that is a higher version than the browser version installed on the client, the browser control will choose the highest document mode available.
The simplest thing is to put a very high decimal number ...

This is from an interview with Gosling and others, about simplicity:
Gosling: For me as a language designer, which I don't really count myself as these days, what "simple" really ended up meaning was could I expect J. Random Developer to hold the spec in his head. That definition says that, for instance, Java isn't -- and in fact a lot of these languages end up with a lot of corner cases, things that nobody really understands. Quiz any C developer about unsigned, and pretty soon you discover that almost no C developers actually understand what goes on with unsigned, what unsigned arithmetic is. Things like that made C complex. The language part of Java is, I think, pretty simple. The libraries you have to look up.
Here is how I show hover text using JavaScript tooltip:
<script language="JavaScript" type="text/javascript" src="javascript/wz_tooltip.js"></script>
<div class="curhand" onmouseover="this.T_WIDTH=125; return escape('Welcome')">Are you New Here?</div>
Using ? is much cleaner.
var ? function_if_exists() : function_if_doesnt_exist();
Arrays in PHP can have Key Value structure.
When using GetAsync with the HttpClient you can add the authorization headers like so:
httpClient.DefaultRequestHeaders.Authorization
= new AuthenticationHeaderValue("Bearer", "Your Oauth token");
This does add the authorization header for the lifetime of the HttpClient so is useful if you are hitting one site where the authorization header doesn't change.
Here is an detailed SO answer
Before initializing map check for is the map is already initiated or not
var container = L.DomUtil.get('map');
if(container != null){
container._leaflet_id = null;
}
It works for me
I agree that the best way is to use the one given by: David Chase, Cu Ly, and others that the simplest way to do this is to use the container: $(this)
property as follows:
$(selectorString).each(function () {
var $this = $(this);
$this.popover({
html: true,
placement: "top",
container: $this,
trigger: "hover",
title: "Popover",
content: "Hey, you hovered on element"
});
});
I want to point out here that the popover in this case will inherit all properties of the current element. So, for example, if you do this for a .btn
element(bootstrap), you won't be able to select text inside the popover. Just wanted to record that since I spent quite some time banging my head on this.
In Anon's answer:
"If you need something from super's __init__
to be done in addition to what is being done in the current class's __init__
, you must call it yourself, since that will not happen automatically"
It's incredible: he is wording exactly the contrary of the principle of inheritance.
It is not that "something from super's __init__
(...) will not happen automatically" , it is that it WOULD happen automatically, but it doesn't happen because the base-class' __init__
is overriden by the definition of the derived-clas __init__
So then, WHY defining a derived_class' __init__
, since it overrides what is aimed at when someone resorts to inheritance ??
It's because one needs to define something that is NOT done in the base-class' __init__
, and the only possibility to obtain that is to put its execution in a derived-class' __init__
function.
In other words, one needs something in base-class' __init__
in addition to what would be automatically done in the base-classe' __init__
if this latter wasn't overriden.
NOT the contrary.
Then, the problem is that the desired instructions present in the base-class' __init__
are no more activated at the moment of instantiation. In order to offset this inactivation, something special is required: calling explicitly the base-class' __init__
, in order to KEEP , NOT TO ADD, the initialization performed by the base-class' __init__
.
That's exactly what is said in the official doc:
An overriding method in a derived class may in fact want to extend rather than simply replace the base class method of the same name. There is a simple way to call the base class method directly: just call BaseClassName.methodname(self, arguments).
http://docs.python.org/tutorial/classes.html#inheritance
That's all the story:
when the aim is to KEEP the initialization performed by the base-class, that is pure inheritance, nothing special is needed, one must just avoid to define an __init__
function in the derived class
when the aim is to REPLACE the initialization performed by the base-class, __init__
must be defined in the derived-class
when the aim is to ADD processes to the initialization performed by the base-class, a derived-class' __init__
must be defined , comprising an explicit call to the base-class __init__
What I feel astonishing in the post of Anon is not only that he expresses the contrary of the inheritance theory, but that there have been 5 guys passing by that upvoted without turning a hair, and moreover there have been nobody to react in 2 years in a thread whose interesting subject must be read relatively often.
There's an alternative, explained in String manifesto
extension String : BidirectionalCollection {
subscript(i: Index) -> Character { return characters[i] }
}
Somehow all these solutions didn't work for me. There is clearly an IE bug in flex-direction:column
.
I only got it working after removing flex-direction
:
flex-wrap: wrap;
align-items: center;
align-content: center;
Setting src attribute didn't work for me. The iframe didn't display the url.
What worked for me was:
window.open(url, "nameof_iframe");
Hope it helps someone.
When you use routerLink like this, then you need to pass the value of the route it should go to. But when you use routerLink with the property binding syntax, like this: [routerLink]
, then it should be assigned a name of the property the value of which will be the route it should navigate the user to.
So to fix your issue, replace this routerLink="['/about']"
with routerLink="/about"
in your HTML.
There were other places where you used property binding syntax when it wasn't really required. I've fixed it and you can simply use the template syntax below:
<nav class="main-nav>
<ul
class="main-nav__list"
ng-sticky
addClass="main-sticky-link"
[ngClass]="ref.click ? 'Navbar__ToggleShow' : ''">
<li class="main-nav__item" routerLinkActive="active">
<a class="main-nav__link" routerLink="/">Home</a>
</li>
<li class="main-nav__item" routerLinkActive="active">
<a class="main-nav__link" routerLink="/about">About us</a>
</li>
</ul>
</nav>
It also needs to know where exactly should it load the template for the Component corresponding to the route it has reached. So for that, don't forget to add a <router-outlet></router-outlet>
, either in your template provided above or in a parent component.
There's another issue with your AppRoutingModule
. You need to export the RouterModule
from there so that it is available to your AppModule
when it imports it. To fix that, export it from your AppRoutingModule
by adding it to the exports
array.
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { MainLayoutComponent } from './layout/main-layout/main-layout.component';
import { AboutComponent } from './components/about/about.component';
import { WhatwedoComponent } from './components/whatwedo/whatwedo.component';
import { FooterComponent } from './components/footer/footer.component';
import { ProjectsComponent } from './components/projects/projects.component';
const routes: Routes = [
{ path: 'about', component: AboutComponent },
{ path: 'what', component: WhatwedoComponent },
{ path: 'contacts', component: FooterComponent },
{ path: 'projects', component: ProjectsComponent},
];
@NgModule({
imports: [
CommonModule,
RouterModule.forRoot(routes),
],
exports: [RouterModule],
declarations: []
})
export class AppRoutingModule { }
When the user wishes to exit all open activities, they should press a button which loads the first Activity that runs when your application starts, clear all the other activities, then have the last remaining activity finish. Have the following code run when the user presses the exit button. In my case, LoginActivity
is the first activity in my program to run.
Intent intent = new Intent(getApplicationContext(), LoginActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("EXIT", true);
startActivity(intent);
The above code clears all the activities except for LoginActivity
. Then put the following code inside the LoginActivity
's onCreate(...)
, to listen for when LoginActivity
is recreated and the 'EXIT' signal was passed:
if (getIntent().getBooleanExtra("EXIT", false)) {
finish();
}
Why is making an exit button in Android so hard?
Android tries hard to discourage you from having an "exit" button in your application, because they want the user to never care about whether or not the programs they use are running in the background or not.
The Android OS developers want your program to be able to survive an unexpected shutdown and power off of the phone, and when the user restarts the program, they pick up right where they left off. So the user can receive a phone call while they use your application, and open maps which requires your application to be freed for more resources.
When the user resumes your application, they pick up right where they left off with no interruption. This exit button is usurping power from the activity manager, potentially causing problems with the automatically managed android program life cycle.
I had this issue and I thought I was crazy. I have been using SSH for 20 years. and git over SSH since 2012... but why couldn't I fetch my bitbucket repository on my home computer?
well, I have two bitbucket accounts and had 4 SSH keys loaded inside my agent. even if my .ssh/config was configured to use the right key. when ssh was initializing the connection, it was using them in order loaded into the agent. so I was getting logged into my personal bitbucket account.
then getting a Forbidden error trying to fetch the repo. makes sense.
I unloaded the key from the agent
ssh-add -d ~/.ssh/personal_rsa
then I could fetch the repos.
... Later I found out I can force it to use the specified identity only
Host bitbucket.org-user2
HostName bitbucket.org
User git
IdentityFile ~/.ssh/user2
IdentitiesOnly yes
I didn't know about that last option IdentitiesOnly
from the bitbucket documentation itself
https://blog.developer.atlassian.com/different-ssh-keys-multiple-bitbucket-accounts/
Unfortunately, that's not supported in the Django template language. There are a couple of suggestions, but they seem a little complex. I would just put a variable in the context:
...
render_to_response('foo.html', {..., 'range': range(10), ...}, ...)
...
and in the template:
{% for i in range %}
...
{% endfor %}
A Type agnostic solution:
for _, key := range reflect.ValueOf(yourMap).MapKeys() {
value := s.MapIndex(key).Interface()
fmt.Println("Key:", key, "Value:", value)
}
Create hash as:
h = Hash.new
=> {}
Now insert into hash as:
h = Hash["one" => 1]
Using pretty much the same approach as used by Burnash, for the final result you can use ...
=regexextract(A1,"[0-9]+")+A2
where A1 houses the string with text and number and A2 houses the date of interest
Use the constructor that takes a File
and a boolean
FileOutputStream(File file, boolean append)
and set the boolean to true
. That way, the data you write will be appended to the end of the file, rather than overwriting what was already there.
Good answers here, but if you want the label respects the user's preferred size category, use preferredFont
.
UIFont.systemFont(ofSize: UIFont.preferredFont(forTextStyle: .body).pointSize, weight: .bold)
select T.object_id, T.name, I.indid, I.rows
from Sys.tables T
left join Sys.sysindexes I
on (I.id = T.object_id and (indid =1 or indid =0 ))
where T.type='U'
Here indid=1
means a CLUSTERED index and indid=0
is a HEAP
Just use SUBSTR function. It takes 3 parameters: String column name, starting index and length of substring:
select SUBSTR(OrderNo, 1, 2) FROM shipment;
Audio
objectsYou don't need to bother with <audio>
elements. HTML 5 lets you access Audio
objects directly:
var snd = new Audio("file.wav"); // buffers automatically when created
snd.play();
There's no support for mixing in current version of the spec.
To play same sound multiple times, create multiple instances of the Audio
object. You could also set snd.currentTime=0
on the object after it finishes playing.
Since the JS constructor doesn't support fallback <source>
elements, you should use
(new Audio()).canPlayType("audio/ogg; codecs=vorbis")
to test whether the browser supports Ogg Vorbis.
If you're writing a game or a music app (more than just a player), you'll want to use more advanced Web Audio API, which is now supported by most browsers.
SQL does not do that. The order of the tuples in the table are not ordered by insertion date. A lot of people include a column that stores that date of insertion in order to get around this issue.
One way of doing it would be also with ACE OLEDB Provider (see also connection strings for Excel). Of course you'd have to have the provider installed and registered. You should have it, if you have Excel installed, but this is something you have to consider when deploying the app.
This is the example of calling the helper method from ExportHelper
: ExportHelper.CreateXlsFromDataTable(myDataTable, @"C:\tmp\export.xls");
The helper for exporting to Excel file using ACE OLEDB:

Just to expand a little on Dirk's example:
It helps to think of a data frame as a list with equal length vectors. That's probably why names
works with a data frame but not a matrix.
The other useful function is dimnames
which returns the names for every dimension. You will notice that the rownames
function actually just returns the first element from dimnames
.
Regarding rownames
and row.names
: I can't tell the difference, although rownames
uses dimnames
while row.names
was written outside of R. They both also seem to work with higher dimensional arrays:
>a <- array(1:5, 1:4)
> a[1,,,]
> rownames(a) <- "a"
> row.names(a)
[1] "a"
> a
, , 1, 1
[,1] [,2]
a 1 2
> dimnames(a)
[[1]]
[1] "a"
[[2]]
NULL
[[3]]
NULL
[[4]]
NULL
Convert both completed
and total
to double
or at least cast them to double
when doing the devision. I.e. cast the varaibles to double not just the result.
Fair warning, there is a floating point precision problem when working with float
and double
.
One of the best posts I've ever come across regarding Security as it relates to REST is over at 1 RainDrop. The MySpace API's use OAuth also for security and you have full access to their custom channels in the RestChess code, which I did a lot of exploration with. This was demo'd at Mix and you can find the posting here.
You can use the system views contained in information_schema
to search in tables, views and (unencrypted) stored procedures with one script. I developed such a script some time ago because I needed to search for field names everywhere in the database.
The script below first lists the tables/views containing the column name you're searching for, and then the stored procedures source code where the column is found. It displays the result in one table distinguishing "BASE TABLE", "VIEW" and "PROCEDURE", and (optionally) the source code in a second table:
DECLARE @SearchFor nvarchar(max)='%CustomerID%' -- search for this string
DECLARE @SearchSP bit = 1 -- 1=search in SPs as well
DECLARE @DisplaySPSource bit = 1 -- 1=display SP source code
-- tables
if (@SearchSP=1) begin
(
select '['+c.table_Schema+'].['+c.table_Name+'].['+c.column_name+']' [schema_object],
t.table_type
from information_schema.columns c
left join information_schema.Tables t on c.table_name=t.table_name
where column_name like @SearchFor
union
select '['+routine_Schema+'].['+routine_Name+']' [schema_object],
'PROCEDURE' as table_type from information_schema.routines
where routine_definition like @SearchFor
and routine_type='procedure'
)
order by table_type, schema_object
end else begin
select '['+c.table_Schema+'].['+c.table_Name+'].['+c.column_name+']' [schema_object],
t.table_type
from information_schema.columns c
left join information_schema.Tables t on c.table_name=t.table_name
where column_name like @SearchFor
order by c.table_Name, c.column_name
end
-- stored procedure (source listing)
if (@SearchSP=1) begin
if (@DisplaySPSource=1) begin
select '['+routine_Schema+'].['+routine_Name+']' [schema.sp], routine_definition
from information_schema.routines
where routine_definition like @SearchFor
and routine_type='procedure'
order by routine_name
end
end
If you run the query, use the "result as text" option - then you can use "find" to locate the search text in the result set (useful for long source code).
Note that you can set @DisplaySPSource
to 0
if you just want to display the SP names, and if you're just looking for tables/views, but not for SPs, you can set @SearchSP
to 0
.
Example result (find CustomerID
in the Northwind database, results displayed via LinqPad):
Note that I've verfied this script with a test view dbo.TestOrders
and it found the CustomerID
in this view even though c.*
was used in the SELECT
statement (referenced table Customers
contains the CustomerID
and hence the view is showing this column).
Note for LinqPad users: In C#, you can use dc.ExecuteQueryDynamic(sqlQueryStr, new object[] {... parameters ...} ).Dump();
and have the parameters as @p0
... @pn
inside the query string. Then you can write a static extension class and save it under My Extensions to be used in your LinqPad queries. The data context can be passed from the query window as DataContextBase dc
via parameter, i.e. public static void SearchDialog(this DataContextBase dc, string searchString = "%")
inside a public static extension class (in LinqPad 6, it is DataContext
). Then you can rewrite the SQL query above as a string with parameters and invoke it from the C# context.

The comparison with an epsilon value is what most people do (even in game programming).
You should change your implementation a little though:

Edit: Christer has added a stack of great info on this topic on a recent blog post. Enjoy.
As this very useful tutorial says:
var age = 0;
// bad
var hasAge = new Boolean(age);
// good
var hasAge = Boolean(age);
// good
var hasAge = !!age;
This site has two pretty simple solutions - just check the code, I provided the descriptions in case you wanted them - saves you some clicks.
http://www.richardlord.net/blog/dates-in-php-and-mysql
1.One common solution is to store the dates in DATETIME fields and use PHPs date() and strtotime() functions to convert between PHP timestamps and MySQL DATETIMEs. The methods would be used as follows -
$mysqldate = date( 'Y-m-d H:i:s', $phpdate );
$phpdate = strtotime( $mysqldate );
2.Our second option is to let MySQL do the work. MySQL has functions we can use to convert the data at the point where we access the database. UNIX_TIMESTAMP will convert from DATETIME to PHP timestamp and FROM_UNIXTIME will convert from PHP timestamp to DATETIME. The methods are used within the SQL query. So we insert and update dates using queries like this -
$query = "UPDATE table SET
datetimefield = FROM_UNIXTIME($phpdate)
WHERE...";
$query = "SELECT UNIX_TIMESTAMP(datetimefield)
FROM table WHERE...";
In the constructor of Startup class, you can access appsettings.json and many other settings using the injected IConfiguration object:
Startup.cs Constructor
public Startup(IConfiguration configuration)
{
Configuration = configuration;
//here you go
var myvalue = Configuration["Grandfather:Father:Child"];
}
public IConfiguration Configuration { get; }
Contents of appsettings.json
{
"Grandfather": {
"Father": {
"Child": "myvalue"
}
}
You can use python-textops3 :
from textops import *
print('\n'.join(cat(f) | grep(search_term)))
with python-textops3 you can use unix-like commands with pipes
Note: please update the date format accordingly.
__formatDate: function(myDate){
var ts = moment.utc(myDate);
return ts.local().format('D-MMM-Y');
}
__formatTime: function(myDate){
var ts = moment.utc(myDate);
return ts.local().format('HH:mm');
},
You can use plt.subplots_adjust
to change the spacing between the subplots (source)
call signature:
subplots_adjust(left=None, bottom=None, right=None, top=None, wspace=None, hspace=None)
The parameter meanings (and suggested defaults) are:
left = 0.125 # the left side of the subplots of the figure
right = 0.9 # the right side of the subplots of the figure
bottom = 0.1 # the bottom of the subplots of the figure
top = 0.9 # the top of the subplots of the figure
wspace = 0.2 # the amount of width reserved for blank space between subplots
hspace = 0.2 # the amount of height reserved for white space between subplots
The actual defaults are controlled by the rc file
Change Manually :
string s = date.Substring(3, 2) +"/" + date.Substring(0, 2) + "/" + date.Substring(6, 4);
From 11/22/2015 it will be converted in 22/11/2015
Looks like you might want the ISO format so that you can retain the timezone.
var dateTime = new Date(1370001284000);
dateTime.toISOString(); // Returns "2013-05-31T11:54:44.000Z"
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString
If the class that is implementing the interface
is an abstract
class, @Override
is useful to ensure that the implementation is for an interface
method; without the @Override
an abstract
class would just compile fine even if the implementation method signature does not match the method declared in the interface
; the mismatched interface
method would remain as unimplemented.
The Java doc cited by @Zhao
The method does override or implement a method declared in a supertype
is clearly referring to an abstract
super class; an interface
can not be called the supertype.
So, @Override
is redundant and not sensible for interface
method implementations in concrete classes.
<>
is equal to !=
i.e, both are used to represent the NOT EQUAL operation. For instance, email <> ''
and email != ''
are same.
To the OP... I also got a type mismatch error the first time I tried running your subroutine. In my case it was cause by non-date-like data in the first cell (i.e. a header). When I changed the contents of the header cell to date-style txt for testing, it ran just fine...
Hope this helps as well.
The trick that worked for me was to remove Integrated Security
from my connection string and add a regular User ID=userName; Password=password
your connection string in the App.config
of your libruary might not be using integrated security but the one created in Web.config
is!
First, remove all explicit setting of modal presentation style in code and do the following:
modalPresentation
style to Over Current context
Provide Context
and Define Context
.
They seem to be working even unchecked.Using Kotlin Language,
EXAMPLE CODE
login_ID.setOnClickListener {
if(email_address_Id.text.isEmpty()){
email_address_Id.error = "Please Enter Email Address"
}
if(Password_ID.text.isEmpty()){
Password_ID.error = "Please Enter Password"
}
}
If you are still getting that error after installing the 64 bit JRE, it means that the JVM running Gurobi package is still using the 32 bit JRE.
Check that you have updated the PATH and JAVA_HOME globally and in the command shell that you are using. (Maybe you just need to exit and restart it.)
Check that your command shell runs the right version of Java by running "java -version" and checking that it says it is a 64bit JRE.
If you are launching the example via a wrapper script / batch file, make sure that the script is using the right JRE. Modify as required ...
You must change the location of MySQL's temporary folder which is '/tmp' in most cases to a location with a bigger disk space. Change it in MySQL's config file.
Basically your server is running out of disk space where /tmp is located.
New, improved answer to an old, frequently asked question...
Double quote ("
) may appear without escaping:
In XML textual content:
<NoEscapeNeeded>He said, "Don't quote me."</NoEscapeNeeded>
In XML attributes delimited by single quotes ('
):
<NoEscapeNeeded name='Pete "Maverick" Mitchell'/>
Note: switching to single quotes ('
) also requires no escaping:
<NoEscapeNeeded name="Pete 'Maverick' Mitchell"/>
Double quote ("
) must be escaped:
In XML attributes delimited by double quotes:
<EscapeNeeded name="Pete "Maverick" Mitchell"/>
Double quote ("
) must be escaped as "
in XML only in very limited contexts.
I've combined some of the advice on this page into something that works for me on iOS 5.
First, you have to add the custom font to your project. Then, you need to follow the advice of @iPhoneDev and add the font to your info.plist file.
After you do that, this works:
UIFont *yourCustomFont = [UIFont fontWithName:@"YOUR-CUSTOM-FONT-POSTSCRIPT-NAME" size:14.0];
[yourUILabel setFont:yourCustomFont];
However, you need to know the Postscript name of your font. Just follow @Daniel Wood's advice and press command-i while you're in FontBook.
Then, enjoy your custom font.
What about one of these?

Class.methods.sort
If you build these pruned images yourself (from some other, older base images) please be careful with the accepted solutions above based on docker image prune
, as the command is blunt and will try to remove also all dependencies required by your latest images (the command should be probably renamed to docker image*s* prune
).
The solution I came up for my docker image build pipelines (where there are daily builds and tags=dates are in the YYYYMMDD
format) is this:
# carefully narrow down the image to be deleted (to avoid removing useful static stuff like base images)
my_deleted_image=mirekphd/ml-cpu-py37-vsc-cust
# define the monitored image (tested for obsolescence), which will be usually the same as deleted one, unless deleting some very infrequently built image which requires a separate "clock"
monitored_image=mirekphd/ml-cache
# calculate the oldest acceptable tag (date)
date_week_ago=$(date -d "last week" '+%Y%m%d')
# get the IDs of obsolete tags of our deleted image
# note we use monitored_image to test for obsolescence
my_deleted_image_obsolete_tag_ids=$(docker images --filter="before=$monitored_image:$date_week_ago" | grep $my_deleted_image | awk '{print $3}')
# remove the obsolete tags of the deleted image
# (note it typically has to be forced using -f switch)
docker rmi -f $my_deleted_image_obsolete_tag_ids
import matplotlib.pyplot as plt
import numpy as np
import scipy.stats as stats
import math
mu = 0
variance = 1
sigma = math.sqrt(variance)
x = np.linspace(mu - 3*sigma, mu + 3*sigma, 100)
plt.plot(x, stats.norm.pdf(x, mu, sigma))
plt.show()
This should work:
$("#table-filters>ul>li.active").removeClass("active");
//Find all `li`s with class `active`, children of `ul`s, children of `table-filters`
This completely removes the modal from the DOM , is working for the "appended" modals as well .
$(document).on('hidden.bs.modal','#pickoptionmodal',function(e){
e.preventDefault();
$("#pickoptionmodal").remove();
});
I would say you have an indentation problem, at least as you wrote it here:
while not os.path.exists(file + "_" + str(i) + extension):
i+=1
print "Already 2x exists..."
print "Renaming"
shutil.copy(path, file + "_" + str(i) + extension)
should be:
while os.path.exists(file + "_" + str(i) + extension):
i+=1
print "Already 2x exists..."
print "Renaming"
shutil.copy(path, file + "_" + str(i) + extension)

The bit I had trouble with was setting up the formatter properly:
class ColouredFormatter(logging.Formatter):
def __init__(self, msg):
logging.Formatter.__init__(self, msg)
self._init_colour = _get_colour()
def close(self):
# restore the colour information to what it was
_set_colour(self._init_colour)
def format(self, record):
# Add your own colourer based on the other examples
_set_colour( LOG_LEVEL_COLOUR[record.levelno] )
return logging.Formatter.format(self, record)
def init():
# Set up the formatter. Needs to be first thing done.
rootLogger = logging.getLogger()
hdlr = logging.StreamHandler()
fmt = ColouredFormatter('%(message)s')
hdlr.setFormatter(fmt)
rootLogger.addHandler(hdlr)
And then to use:
import coloured_log
import logging
coloured_log.init()
logging.info("info")
logging.debug("debug")
coloured_log.close() # restore colours
you can update the setting under init.ora in oraclexe\app\oracle\product\11.2.0\server\config\scripts
just add .col-xs-12 to your responsive image. It's should work.
Here's a really nice and simple way of doing it with really easy to follow instructions using a custom MultiButtonAttribute:
To summarise, make your submit buttons like this:
<input type="submit" value="Cancel" name="action" />
<input type="submit" value="Create" name="action" />
Your actions like this:
[HttpPost]
[MultiButton(MatchFormKey="action", MatchFormValue="Cancel")]
public ActionResult Cancel()
{
return Content("Cancel clicked");
}
[HttpPost]
[MultiButton(MatchFormKey = "action", MatchFormValue = "Create")]
public ActionResult Create(Person person)
{
return Content("Create clicked");
}
And create this class:
[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public class MultiButtonAttribute : ActionNameSelectorAttribute
{
public string MatchFormKey { get; set; }
public string MatchFormValue { get; set; }
public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
{
return controllerContext.HttpContext.Request[MatchFormKey] != null &&
controllerContext.HttpContext.Request[MatchFormKey] == MatchFormValue;
}
}
Its Ctrl + Shift + r
For me, there was only one option to discard all.
<asp:RadioButtonList ID="rblRequestType">
<asp:ListItem Selected="True" Value="value1">Value1</asp:ListItem>
<asp:ListItem Value="Value2">Value2</asp:ListItem>
</asp:RadioButtonList>
You can set checked like this.
var radio0 = $("#rblRequestType_0");
var radio1 = $("#rblRequestType_1");
radio0.checked = true;
radio1.checked = true;
The answer by @Mobilpadde is nice. But this is my solution with regex using preg_replace which might be faster according to my tests.
echo preg_replace('/<br\s?\/?>/i', "\r\n", "testing<br/><br /><BR><br>");
function function_one() {
preg_replace('/<br\s?\/?>/i', "\r\n", "testing<br/><br /><BR><br>");
}
function function_two() {
str_ireplace(['<br />','<br>','<br/>'], "\r\n", "testing<br/><br /><BR><br>");
}
function benchmark() {
$count = 10000000;
$before = microtime(true);
for ($i=0 ; $i<$count; $i++) {
function_one();
}
$after = microtime(true);
echo ($after-$before)/$i . " sec/function one\n";
$before = microtime(true);
for ($i=0 ; $i<$count; $i++) {
function_two();
}
$after = microtime(true);
echo ($after-$before)/$i . " sec/function two\n";
}
benchmark();
Results:
1.1471637010574E-6 sec/function one (preg_replace)
1.6027762889862E-6 sec/function two (str_ireplace)
I figured this wouldn't be UTF, but I just found a pretty simple solution that seems to work...
Get-Content path/to/file.ext | out-file -encoding ASCII targetFile.ext
For me this results in a utf-8 without bom file regardless of the source format.
For PowerShell 3.0
$PSCommandPath
Contains the full path and file name of the script that is being run.
This variable is valid in all scripts.
The function is then:
function Get-ScriptDirectory {
Split-Path -Parent $PSCommandPath
}
Try
set expandtab
for soft tabs.
To fix pre-existing tabs:
:%s/\t/ /g
I used two spaces since you already set your tabstop to 2 spaces.
Define a class like this :
public class myclass {
string id ;
string title ;
string content;
}
public class program {
public void Main () {
List<myclass> objlist = new List<myclass> () ;
foreach (var value in objlist) {
TextBox1.Text = value.id ;
TextBox2.Text= value.title;
TextBox3.Text= value.content ;
}
}
}
I tried to draw a sketch and you can improve it in many ways. Instead of defining class "myclass", you can define struct.
There doesn't seem to be a standardized default value. I have the feeling the default is 0
, and the timeout event left totally dependent on browser and network settings.
For IE, there is a timeout property for XMLHTTPRequests here. It defaults to null, and it says the network stack is likely to be the first to time out (which will not generate an ontimeout event by the way).
You may have outlets to UI Element but not IBOutlet property in .h File
For all UI element in Connection Attribute check outlets and it corresponding property in .h header file.
May be missing one or more property entry in .h file.
As you specify in your attrs.xml
your adSize attribute belongs to the namespace com.google.ads.AdView
. Try to change:
android:adUnitId="a14bd6d2c63e055" android:adSize="BANNER"
to
ads:adUnitId="a14bd6d2c63e055" ads:adSize="BANNER"
and it should work.
This is essentially the same thing. Use whatever you find more convenient.
After deserializing the JSON, you have a python object. Use the regular object methods.
In this case you have a list made of dictionaries:
json_object[0].items()
json_object[0]["title"]
etc.
Is your function, which sets the hidden form value, being called? It is not in this example. You should have no problem modifying a hidden value before posting the form back to the server.
There is a whole page in the MATLAB documentation dedicated to this topic: Array vs. Matrix Operations. The gist of it is below:
MATLAB® has two different types of arithmetic operations: array operations and matrix operations. You can use these arithmetic operations to perform numeric computations, for example, adding two numbers, raising the elements of an array to a given power, or multiplying two matrices.
Matrix operations follow the rules of linear algebra. By contrast, array operations execute element by element operations and support multidimensional arrays. The period character (
.
) distinguishes the array operations from the matrix operations. However, since the matrix and array operations are the same for addition and subtraction, the character pairs.+
and.-
are unnecessary.

We dont need redux-persist we can simply use redux for persistance.
react-redux + AsyncStorage = redux-persist
so inside createsotre file simply add these lines
store.subscribe(async()=> await AsyncStorage.setItem("store", JSON.stringify(store.getState())))
this will update the AsyncStorage whenever there are some changes in the redux store.
Then load the json converted store. when ever the app loads. and set the store again.
Because redux-persist creates issues when using wix react-native-navigation. If that's the case then I prefer to use simple redux with above subscriber function
Use preg_replace()
and instead of [ \t\n\r]
use \s
:
$output = preg_replace('!\s+!', ' ', $input);
From Regular Expression Basic Syntax Reference:
\d, \w and \s
Shorthand character classes matching digits, word characters (letters, digits, and underscores), and whitespace (spaces, tabs, and line breaks). Can be used inside and outside character classes.
As Nayan said the Path has to updated properly in my case the apache-maven was installed in C:\apache-maven and settings.xml was found inside C:\apache-maven\conf\settings.xml
if this doesn't work go to your local repos
in my case C:\Users\<<"name">>.m2\
and search for .lastUpdated and delete them
then build the maven
An alternative to 'LOAD DATA' is available in which the data will not be moved from your existing source location to hive data warehouse location.
You can use ALTER TABLE command with 'LOCATION' option. Here is below required command
ALTER TABLE table_name ADD PARTITION (date_col='2017-02-07') LOCATION 'hdfs/path/to/location/'
The only condition here is, the location should be a directory instead of file.
Hope this will solve the problem.
You can use the some method:
console.log(channelArray.some(x => x === "three")); // true
You can use the find method:
console.log(channelArray.find(x => x === "three")); // three
Or you can use the indexOf method:
console.log(channelArray.indexOf("three")); // 2
Yes you can pass the model that you have shown using
return RedirectToAction("GetStudent", "Student", student1 );
assuming student1
is an instance of Student
which will generate the following url (assuming your using the default routes and the value of student1
are ID=4
and Name="Amit"
)
.../Student/GetStudent/4?Name=Amit
Internally the RedirectToAction()
method builds a RouteValueDictionary
by using the .ToString()
value of each property in the model. However, binding will only work if all the properties in the model are simple properties and it fails if any properties are complex objects or collections because the method does not use recursion. If for example, Student
contained a property List<string> Subjects
, then that property would result in a query string value of
....&Subjects=System.Collections.Generic.List'1[System.String]
and binding would fail and that property would be null
When rebase or push to head/master this error may occurred
remote: GitLab: You are not allowed to access some of the refs!
To git@giturl:main/xyz.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@giturl:main/xyz.git'
To resolve this issue in git dashboard should remove master branch from "Protected branches"
then you can run this command
git push -f origin master
or
git rebase --onto temp $1 master
localhost: You can use: domain: ".app.localhost"
and it will work. The 'domain' parameter needs 1 or more dots in the domain name for setting cookies. Then you can have sessions working across localhost subdomains such as: api.app.localhost:3000
.
After looking at the code you're having typos, here is the updated code
var clicks = 0; // should be var not int
function clickME() {
clicks += 1;
document.getElementById("clicks").innerHTML = clicks; //getElementById() not getElementByID() Which you corrected in edit
}
Note: Don't use in-built handlers, as .click()
is javascript function try giving different name like clickME()
Move all of your state and your handleClick
function from Header
to your MainWrapper
component.
Then pass values as props to all components that need to share this functionality.
class MainWrapper extends React.Component {
constructor() {
super();
this.state = {
sidbarPushCollapsed: false,
profileCollapsed: false
};
this.handleClick = this.handleClick.bind(this);
}
handleClick() {
this.setState({
sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
profileCollapsed: !this.state.profileCollapsed
});
}
render() {
return (
//...
<Header
handleClick={this.handleClick}
sidbarPushCollapsed={this.state.sidbarPushCollapsed}
profileCollapsed={this.state.profileCollapsed} />
);
Then in your Header's render() method, you'd use this.props
:
<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>
Instead of JSONObject , you can use ObjectMapper to convert java object to json string
ObjectMapper mapper = new ObjectMapper();
String requestBean = mapper.writeValueAsString(yourObject);
table {

}
calling getImageData every time will slow the process ... to speed up things i recommend store image data and then you can get pix value easily and quickly, so do something like this for better performance
// keep it global
let imgData = false; // initially no image data we have
// create some function block
if(imgData === false){
// fetch once canvas data
var ctx = canvas.getContext("2d");
imgData = ctx.getImageData(0, 0, canvas.width, canvas.height);
}
// Prepare your X Y coordinates which you will be fetching from your mouse loc
let x = 100; //
let y = 100;
// locate index of current pixel
let index = (y * imgData.width + x) * 4;
let red = imgData.data[index];
let green = imgData.data[index+1];
let blue = imgData.data[index+2];
let alpha = imgData.data[index+3];
// Output
console.log('pix x ' + x +' y '+y+ ' index '+index +' COLOR '+red+','+green+','+blue+','+alpha);

Use a regular expression to accomplish this.

String formatting, using the new-style .format()
method (with the defaults .format() provides):
'{}{}'.format(s, i)
Or the older, but "still sticking around", %
-formatting:
'%s%d' %(s, i)
In both examples above there's no space between the two items concatenated. If space is needed, it can simply be added in the format strings.
These provide a lot of control and flexibility about how to concatenate items, the space between them etc. For details about format specifications see this.
Single quotes are characters (char
), double quotes are null-terminated strings (char *
).
char c = 'x';
char *s = "Hello World";
Your submit button doesn't have a name. Add name="submit" to your submit button.
If you view source on the form in the browser, you'll see how it submits to self - the form's action attribute will contain the name of the current script - therefore when the form submits, it submits to itself. Edit for vanity sake!
I also had a same requirement to delete an element from array which is in state.
const array= [...this.state.selectedOption]
const found= array.findIndex(x=>x.index===k)
if(found !== -1){
this.setState({
selectedOption:array.filter(x => x.index !== k)
})
}
First I copied the elements into an array. Then checked whether the element exist in the array or not. Then only I have deleted the element from the state using the filter option.
Apply style="text-align: right"
to the input tag. This will allow entry to be right-justified, and (at least in Firefox 3, IE 7 and Safari) will even appear to flow from the right.
8.833333333339
(or 8.833333333333334
, the result of 106.00/12
) properly rounded to two decimal places is 8.83
. Mathematically it sounds like what you want is a ceiling function. The one in Python's math
module is named ceil
:
import math
v = 8.8333333333333339
print(math.ceil(v*100)/100) # -> 8.84
Respectively, the floor and ceiling functions generally map a real number to the largest previous or smallest following integer which has zero decimal places — so to use them for 2 decimal places the number is first multiplied by 102 (or 100) to shift the decimal point and is then divided by it afterwards to compensate.
If you don't want to use the math
module for some reason, you can use this (minimally tested) implementation I just wrote:
def ceiling(x):
n = int(x)
return n if n-1 < x <= n else n+1
From the sample output it appears that they rounded up the monthly payment, which is what many call the effect of the ceiling function. This means that each month a little more than 1/12 of the total amount is being paid. That made the final payment a little smaller than usual — leaving a remaining unpaid balance of only 8.76
.
It would have been equally valid to use normal rounding producing a monthly payment of 8.83
and a slightly higher final payment of 8.87
. However, in the real world people generally don't like to have their payments go up, so rounding up each payment is the common practice — it also returns the money to the lender more quickly.
All answers are awesome and explained everything very well
but I just want to point out different way for passing args to main method
in visual studio
like this image
and happy knowing secrets
This worked for me.
sudo adduser <username> www-data
sudo chown -R www-data:www-data /var/www
sudo chmod -R g+rwX /var/www
Then logout or reboot.
If SELinux
complains, try the following
sudo semanage fcontext -a -t httpd_sys_rw_content_t '/var/www(/.*)?'
sudo restorecon -Rv '/var/www(/.*)?'
For this html:
<div class="outer">
<div class="inner"></div>
</div>
This selector should work:
$('.outer > .inner')
You can write in this way

column_name decimal(18, 2) NOT NULL CONSTRAINT Constant_name DEFAULT 0
GO
ALTER TABLE Table_name SET (LOCK_ESCALATION = TABLE)
GO
COMMIT
The XmlTextWriter is usually used for generating (not updating) XML content. When you load the xml file into an XmlDocument, you don't need a separate writer.
Just update the node you have selected and .Save() that XmlDocument.
More universal can be: for each v Selection : v.value = "'" & v.value : next and selecting range of cells before execution
Because $xml->xpath
always return an array, and strlen
expects a string.

Use application/javascript
as content type instead of text/javascript
text/javascript
is mentioned obsolete. See reference docs.
http://www.iana.org/assignments/media-types/application
Also see this question on SO.
UPDATE:
I have tried executing the code you have given and the below didn't work.
res.setHeader('content-type', 'text/javascript');
res.send(JS_Script);
This is what worked for me.
res.setHeader('content-type', 'text/javascript');
res.end(JS_Script);
As robertklep has suggested, please refer to the node http docs, there is no response.send()
there.
You can set timeout like this,
con.setConnectTimeout(connectTimeout);
con.setReadTimeout(socketTimeout);
To calculate MD5 hash of CLOB content field with my desired encoding without implicitly recoding content to AL32UTF8, I've used this code:
create or replace function clob2blob(AClob CLOB) return BLOB is
Result BLOB;
o1 integer;
o2 integer;
c integer;
w integer;
begin
o1 := 1;
o2 := 1;
c := 0;
w := 0;
DBMS_LOB.CreateTemporary(Result, true);
DBMS_LOB.ConvertToBlob(Result, AClob, length(AClob), o1, o2, 0, c, w);
return(Result);
end clob2blob;
/
update my_table t set t.hash = (rawtohex(DBMS_CRYPTO.Hash(clob2blob(t.content),2)));
"project property - CUDA Runtime API - GPU - NVCC Compilation Type"
Set the 64 bit compile option -m64 -cubin
The hint is at compile log. Like this:
nvcc.exe ~~~~~~ -machine 32 -ccbin ~~~~~
That "-machine 32"
is problem.
First set 64bit compile option, next re setting hybrid compile option. Then u can see the succeed.
If there are multiple certificates in a pfx file (key + corresponding certificate and a CA certificate) then this command worked well for me:
certutil -importpfx c:\somepfx.pfx this works but still a password is needed to be typed in manually for private key. Including -p and "password" cause error too many arguments for certutil on XP
You can use the os/signal package to handle incoming signals. Ctrl+C is SIGINT, so you can use this to trap os.Interrupt
.
c := make(chan os.Signal, 1)
signal.Notify(c, os.Interrupt)
go func(){
for sig := range c {
// sig is a ^C, handle it
}
}()
The manner in which you cause your program to terminate and print information is entirely up to you.
You can do it programatically: Or without action bar
//It's enough to remove the line
requestWindowFeature(Window.FEATURE_NO_TITLE);
//But if you want to display full screen (without action bar) write too
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.your_activity);
you can use the Utility mettod. Arrays.deeptoString();
public static void main(String[] args) {
int twoD[][] = new int[4][];
twoD[0] = new int[1];
twoD[1] = new int[2];
twoD[2] = new int[3];
twoD[3] = new int[4];
System.out.println(Arrays.deepToString(twoD));
}
C++ supplies a string
class that can be used like this:
#include <string>
#include <iostream>
int main() {
std::string Something = "Some text";
std::cout << Something << std::endl;
}
Quick guide to setup a cron job
Create a new text file, example: mycronjobs.txt
For each daily job (00:00, 03:45), save the schedule lines in mycronjobs.txt
00 00 * * * ruby path/to/your/script.rb
45 03 * * * path/to/your/script2.sh
Send the jobs to cron (everytime you run this, cron deletes what has been stored and updates with the new information in mycronjobs.txt)
crontab mycronjobs.txt
Extra Useful Information
See current cron jobs
crontab -l
Remove all cron jobs
crontab -r
Download javax.mail.jar
and add it to your project using the following steps:
Given the rules you specified:
upto length 13 and including character + infront.
(and also incorporating the min length of 10 in your code)
You're going to want a regex that looks like this:
^\+[0-9]{10,13}$
With the min and max lengths encoded in the regex, you can drop those conditions from your if()
block.
Off topic: I'd suggest that a range of 10 - 13 is too limiting for an international phone number field; you're almost certain to find valid numbers that are both longer and shorter than this. I'd suggest a range of 8 - 20 to be safe.
[EDIT] OP states the above regex doesn't work due to the escape sequence. Not sure why, but an alternative would be:
^[+][0-9]{10,13}$
[EDIT 2]
OP now adds that the +
sign should be optional. In this case, the regex needs a question mark after the +
, so the example above would now look like this:
^[+]?[0-9]{10,13}$
Actually one detail is missing from the answer that is selected as accepted (from Phil Ross)....
it DOES work in Chrome, and the solution is really silly!!
Both the parent and the element onto which you want to control page-breaking must be declared as:
position: relative
check out this fiddle: http://jsfiddle.net/petersphilo/QCvA5/5/show/
This is true for:
page-break-before
page-break-after
page-break-inside
However, controlling page-break-inside in Safari does not work (in 5.1.7, at least)
i hope this helps!!!
PS: The question below brought up that fact that recent versions of Chrome no longer respect this, even with the position: relative; trick. However, they do seem to respect:
-webkit-region-break-inside: avoid;
see this fiddle: http://jsfiddle.net/petersphilo/QCvA5/23/show
so i guess we have to add that now...
Hope this helps!
It is working for me,try this one:
public void clearFragmentBackStack() {
FragmentManager fm = getSupportFragmentManager();
for (int i = 0; i < fm.getBackStackEntryCount() - 1; i++) {
fm.popBackStack();
}
}
@T0xicCode's answer is correct, but I thought I would expand on the details since it actually took me about 20 hours to finally get a working solution implemented.
If you're looking to run Nginx in its own container and use it as a reverse proxy to load balance multiple applications on the same server instance then the steps you need to follow are as such:
Link Your Containers
When you docker run
your containers, typically by inputting a shell script into User Data
, you can declare links to any other running containers. This means that you need to start your containers up in order and only the latter containers can link to the former ones. Like so:
#!/bin/bash
sudo docker run -p 3000:3000 --name API mydockerhub/api
sudo docker run -p 3001:3001 --link API:API --name App mydockerhub/app
sudo docker run -p 80:80 -p 443:443 --link API:API --link App:App --name Nginx mydockerhub/nginx
So in this example, the API
container isn't linked to any others, but the
App
container is linked to API
and Nginx
is linked to both API
and App
.
The result of this is changes to the env
vars and the /etc/hosts
files that reside within the API
and App
containers. The results look like so:
/etc/hosts
Running cat /etc/hosts
within your Nginx
container will produce the following:
172.17.0.5 0fd9a40ab5ec
127.0.0.1 localhost
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.17.0.3 App
172.17.0.2 API
ENV Vars
Running env
within your Nginx
container will produce the following:
API_PORT=tcp://172.17.0.2:3000
API_PORT_3000_TCP_PROTO=tcp
API_PORT_3000_TCP_PORT=3000
API_PORT_3000_TCP_ADDR=172.17.0.2
APP_PORT=tcp://172.17.0.3:3001
APP_PORT_3001_TCP_PROTO=tcp
APP_PORT_3001_TCP_PORT=3001
APP_PORT_3001_TCP_ADDR=172.17.0.3
I've truncated many of the actual vars, but the above are the key values you need to proxy traffic to your containers.
To obtain a shell to run the above commands within a running container, use the following:
sudo docker exec -i -t Nginx bash
You can see that you now have both /etc/hosts
file entries and env
vars that contain the local IP address for any of the containers that were linked. So far as I can tell, this is all that happens when you run containers with link options declared. But you can now use this information to configure nginx
within your Nginx
container.
Configuring Nginx
This is where it gets a little tricky, and there's a couple of options. You can choose to configure your sites to point to an entry in the /etc/hosts
file that docker
created, or you can utilize the ENV
vars and run a string replacement (I used sed
) on your nginx.conf
and any other conf files that may be in your /etc/nginx/sites-enabled
folder to insert the IP values.
OPTION A: Configure Nginx Using ENV Vars
This is the option that I went with because I couldn't get the
/etc/hosts
file option to work. I'll be trying Option B soon enough and update this post with any findings.
The key difference between this option and using the /etc/hosts
file option is how you write your Dockerfile
to use a shell script as the CMD
argument, which in turn handles the string replacement to copy the IP values from ENV
to your conf file(s).
Here's the set of configuration files I ended up with:

sed -i 's/APP_IP/'"$APP_PORT_3001_TCP_ADDR"'/g' /etc/nginx/sites-enabled/app.myapp.com
service nginx start
I'll leave it up to you to do your homework about most of the contents of nginx.conf
and api.myapp.conf
.
The magic happens in Nginx-Startup.sh
where we use sed
to do string replacement on the APP_IP
placeholder that we've written into the upstream
block of our api.myapp.conf
and app.myapp.conf
files.
This ask.ubuntu.com question explains it very nicely: Find and replace text within a file using commands
GOTCHA On OSX,
sed
handles options differently, the-i
flag specifically. On Ubuntu, the-i
flag will handle the replacement 'in place'; it will open the file, change the text, and then 'save over' the same file. On OSX, the-i
flag requires the file extension you'd like the resulting file to have. If you're working with a file that has no extension you must input '' as the value for the-i
flag.GOTCHA To use ENV vars within the regex that
sed
uses to find the string you want to replace you need to wrap the var within double-quotes. So the correct, albeit wonky-looking, syntax is as above.
So docker has launched our container and triggered the Nginx-Startup.sh
script to run, which has used sed
to change the value APP_IP
to the corresponding ENV
variable we provided in the sed
command. We now have conf files within our /etc/nginx/sites-enabled
directory that have the IP addresses from the ENV
vars that docker set when starting up the container. Within your api.myapp.conf
file you'll see the upstream
block has changed to this:
upstream api_upstream{
server 172.0.0.2:3000;
}
The IP address you see may be different, but I've noticed that it's usually 172.0.0.x
.
You should now have everything routing appropriately.
GOTCHA You cannot restart/rerun any containers once you've run the initial instance launch. Docker provides each container with a new IP upon launch and does not seem to re-use any that its used before. So
api.myapp.com
will get 172.0.0.2 the first time, but then get 172.0.0.4 the next time. ButNginx
will have already set the first IP into its conf files, or in its/etc/hosts
file, so it won't be able to determine the new IP forapi.myapp.com
. The solution to this is likely to useCoreOS
and itsetcd
service which, in my limited understanding, acts like a sharedENV
for all machines registered into the sameCoreOS
cluster. This is the next toy I'm going to play with setting up.
OPTION B: Use /etc/hosts
File Entries
This should be the quicker, easier way of doing this, but I couldn't get it to work. Ostensibly you just input the value of the /etc/hosts
entry into your api.myapp.conf
and app.myapp.conf
files, but I couldn't get this method to work.
UPDATE: See @Wes Tod's answer for instructions on how to make this method work.
Here's the attempt that I made in api.myapp.conf
:
upstream api_upstream{
server API:3000;
}
Considering that there's an entry in my /etc/hosts
file like so: 172.0.0.2 API
I figured it would just pull in the value, but it doesn't seem to be.
I also had a couple of ancillary issues with my Elastic Load Balancer
sourcing from all AZ's so that may have been the issue when I tried this route. Instead I had to learn how to handle replacing strings in Linux, so that was fun. I'll give this a try in a while and see how it goes.
To remove the decimals from your double, take a look at this output
Obj C
double hellodouble = 10.025;
NSLog(@"Your value with 2 decimals: %.2f", hellodouble);
NSLog(@"Your value with no decimals: %.0f", hellodouble);
The output will be:
10.02
10
Swift 2.1 and Xcode 7.2.1
let hellodouble:Double = 3.14159265358979
print(String(format:"Your value with 2 decimals: %.2f", hellodouble))
print(String(format:"Your value with no decimals: %.0f", hellodouble))
The output will be:
3.14

I figured it out through trial and error... the real chink in the armor was a little known setting in IIS in the Configuration Editor
for the website in
Section: system.webServer/security/authentication/windowsAuthentication
From: ApplicationHost.config <locationpath='ServerName/SiteName' />
called useAppPoolCredentials
(which is set to False
by default. Set this to True
and life becomes great again!!! Hope this saves pain for the next guy....
Building and simplifying @kindall's answer, here's what I typically use:
v_print = None
def main()
parser = argparse.ArgumentParser()
parser.add_argument('-v', '--verbosity', action="count",
help="increase output verbosity (e.g., -vv is more than -v)")
args = parser.parse_args()
if args.verbosity:
def _v_print(*verb_args):
if verb_args[0] > (3 - args.verbosity):
print verb_args[1]
else:
_v_print = lambda *a: None # do-nothing function
global v_print
v_print = _v_print
if __name__ == '__main__':
main()
This then provides the following usage throughout your script:
v_print(1, "INFO message")
v_print(2, "WARN message")
v_print(3, "ERROR message")
And your script can be called like this:
% python verbose-tester.py -v
ERROR message
% python verbose=tester.py -vv
WARN message
ERROR message
% python verbose-tester.py -vvv
INFO message
WARN message
ERROR message
A couple notes:
3
that sets the upper bound for your logging, but I accept that as a compromise for simplicity.v_print
to work throughout your program, you have to do the junk with the global. It's no fun, but I challenge somebody to find a better way.I would suggest using the replace-last npm package.
var str = 'one two, one three, one four, one';_x000D_
var result = replaceLast(str, 'one', 'finish');_x000D_
console.log(result);
_x000D_
<script src="https://unpkg.com/replace-last@latest/replaceLast.js"></script>
_x000D_
This works for string and regex replacements.
You can do this without additional tools in VBScript:
Do Until WScript.StdIn.AtEndOfStream
WScript.StdOut.WriteLine WScript.StdIn.ReadLine
Loop
Put the above lines in a file unix2dos.vbs
and run it like this:
cscript //NoLogo unix2dos.vbs <C:\path\to\input.txt >C:\path\to\output.txt
or like this:
type C:\path\to\input.txt | cscript //NoLogo unix2dos.vbs >C:\path\to\output.txt
You can also do it in PowerShell:
(Get-Content "C:\path\to\input.txt") -replace "`n", "`r`n" |
Set-Content "C:\path\to\output.txt"
which could be further simplified to this:
(Get-Content "C:\path\to\input.txt") | Set-Content "C:\path\to\output.txt"
The above statement works without an explicit replacement, because Get-Content
implicitly splits input files at any kind of linebreak (CR, LF, and CR-LF), and Set-Content
joins the input array with Windows linebreaks (CR-LF) before writing it to a file.
It can also be used as below:
from datetime import datetime
start_date = datetime(2016,3,1)
end_date = datetime(2016,3,10)
Converter:
public class NullableToVisibilityConverter: IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
return value == null ? Visibility.Collapsed : Visibility.Visible;
}
}
Binding:
Visibility="{Binding PropertyToBind, Converter={StaticResource nullableToVisibilityConverter}}"
For react-router
v3.x
I had the same issue where I needed a confirmation message for any unsaved change on the page. In my case, I was using React Router v3, so I could not use <Prompt />
, which was introduced from React Router v4.
I handled 'back button click' and 'accidental link click' with the combination of setRouteLeaveHook
and history.pushState()
, and handled 'reload button' with onbeforeunload
event handler.
setRouteLeaveHook (doc) & history.pushState (doc)
Using only setRouteLeaveHook was not enough. For some reason, the URL was changed although the page remained the same when 'back button' was clicked.
// setRouteLeaveHook returns the unregister method
this.unregisterRouteHook = this.props.router.setRouteLeaveHook(
this.props.route,
this.routerWillLeave
);
...
routerWillLeave = nextLocation => {
// Using native 'confirm' method to show confirmation message
const result = confirm('Unsaved work will be lost');
if (result) {
// navigation confirmed
return true;
} else {
// navigation canceled, pushing the previous path
window.history.pushState(null, null, this.props.route.path);
return false;
}
};
onbeforeunload (doc)
It is used to handle 'accidental reload' button
window.onbeforeunload = this.handleOnBeforeUnload;
...
handleOnBeforeUnload = e => {
const message = 'Are you sure?';
e.returnValue = message;
return message;
}
Below is the full component that I have written
this.props.router
. this.props.route
is passed down from the calling componentnote that currentState
is passed as prop to have initial state and to check any change
import React from 'react';
import PropTypes from 'prop-types';
import _ from 'lodash';
import { withRouter } from 'react-router';
import Component from '../Component';

constructor(props) {
super(props);
this.state = {
// initialize the initial state to check any change
initialState: _.cloneDeep(props.currentState),
hookMounted: false
};
}
componentDidUpdate() {
// I used the library called 'lodash'
// but you can use your own way to check any unsaved changed
const unsaved = !_.isEqual(
this.state.initialState,
this.props.currentState
);
if (!unsaved && this.state.hookMounted) {
// unregister hooks
this.setState({ hookMounted: false });
this.unregisterRouteHook();
window.onbeforeunload = null;
} else if (unsaved && !this.state.hookMounted) {
// register hooks
this.setState({ hookMounted: true });
this.unregisterRouteHook = this.props.router.setRouteLeaveHook(
this.props.route,
this.routerWillLeave
);
window.onbeforeunload = this.handleOnBeforeUnload;
}
}
componentWillUnmount() {
// unregister onbeforeunload event handler
window.onbeforeunload = null;
}
handleOnBeforeUnload = e => {
const message = 'Are you sure?';
e.returnValue = message;
return message;
};
routerWillLeave = nextLocation => {
const result = confirm('Unsaved work will be lost');
if (result) {
return true;
} else {

As of HttpComponents 4.2+
there is a new class URIBuilder, which provides convenient way for generating URIs.
You can use either create URI directly from String URL:
List<NameValuePair> listOfParameters = ...;
URI uri = new URIBuilder("http://example.com:8080/path/to/resource?mandatoryParam=someValue")
.addParameter("firstParam", firstVal)
.addParameter("secondParam", secondVal)
.addParameters(listOfParameters)
.build();
Otherwise, you can specify all parameters explicitly:
URI uri = new URIBuilder()
.setScheme("http")
.setHost("example.com")
.setPort(8080)
.setPath("/path/to/resource")
.addParameter("mandatoryParam", "someValue")
.addParameter("firstParam", firstVal)
.addParameter("secondParam", secondVal)
.addParameters(listOfParameters)
.build();
Once you have created URI
object, then you just simply need to create HttpGet
object and perform it:
//create GET request
HttpGet httpGet = new HttpGet(uri);
//perform request
httpClient.execute(httpGet ...//additional parameters, handle response etc.
Did you try putting all your jars directly in the WEB-INF/lib
dir instead of sub-dirs of that?
No WEB-INF/lib/spring/org.springframework.aop-3.0.0.RELEASE.jar
, just WEB-INF/lib/org.springframework.aop-3.0.0.RELEASE.jar
Same with the rest of the jars.
If you want this in config, you can set npm config like so:
npm config set prefix "$(pwd)/vendor/node_modules"
or
npm config set prefix "$HOME/vendor/node_modules"
Check your config with
npm config ls -l
Or as @pje says and use the --prefix
flag
I encountered the same problem whilst trying to get Shinken 2.0.3 to fire up on Ubuntu. Eventually I did a full uninstall then reinstalled Shinken with pip -v
. As it cleaned up, it mentioned:
Warning: missing python-pycurl lib, you MUST install it before launch the shinken daemons
Installed that with apt-get
, and all the brokers fired up as expected :-)
In support of the accepted answer I would like to add that the function below seems to change the values in the original array to be sorted so that not only will it sort lower case but upper case values will also be changed to lower case. This is a problem for me because even though I wish to see Mary next to mary, I do not wish that the case of the first value Mary be changed to lower case.
myArray.sort(
function(a, b) {
if (a.toLowerCase() < b.toLowerCase()) return -1;
if (a.toLowerCase() > b.toLowerCase()) return 1;
return 0;
}
);
In my experiments, the following function from the accepted answer sorts correctly but does not change the values.
["Foo", "bar"].sort(function (a, b) {
return a.toLowerCase().localeCompare(b.toLowerCase());
});
I tried this code and it works well!
final ZonedDateTime now = ZonedDateTime.now(ZoneOffset.UTC);
final ZonedDateTime startofDay =
now.toLocalDate().atStartOfDay(ZoneOffset.UTC);
final ZonedDateTime endOfDay =
now.toLocalDate().atTime(LocalTime.MAX).atZone(ZoneOffset.UTC);
<manifest xmlns:tools="http://schemas.android.com/tools" ... >
<uses-sdk tools:overrideLibrary="nl.innovalor.ocr, nl.innovalor.corelib" />
I was facing the issue of conflict between different min sdk versions. So this solution worked for me.
If, like me, you're running gVim on Windows then your .vimrc file may be sourcing another 'example' Vimscript file that automatically sets textwidth
(in my case to 78
) for text files.
My answer to a similar question as this one – How to stop gVim wrapping text at column 80 – on the Vi and Vim Stack Exchange site:
In my case, Vitor's comment suggested I run the following:
:verbose set tw?
Doing so gave me the following output:
textwidth=78 Last set from C:\Program Files (x86)\Vim\vim74\vimrc_example.vim
In vimrc_example.vim, I found the relevant lines:
" Only do this part when compiled with support for autocommands. if has("autocmd") ... " For all text files set 'textwidth' to 78 characters. autocmd FileType text setlocal textwidth=78 ...
And I found that my .vimrc is sourcing that file:
source $VIMRUNTIME/vimrc_example.vim
In my case, I don't want
textwidth
to be set for any files, so I just commented out the relevant line in vimrc_example.vim.
For C++ users, to increase the Build console output size see here
ie Windows > Preference > C/C++ > Build > Console
//refresh all iframes on page
var f_list = document.getElementsByTagName('iframe');
for (var i = 0, f; f = f_list[i]; i++) {
f.src = f.src;
}
If doing quoted answers, you can do
$commaList = '"'.implode( '" , " ', $fruit). '"';
the above assumes that fruit is non-null. If you don't want to make that assumption you can use an if-then-else statement or ternary (?:) operator.
if (parent.getContext() instanceof yourActivity) {
//execute code
}
this condition will enable you to execute something if the Activity which has the GroupView
that requesting views from the getView()
method of your adapter
is yourActivity
NOTE : parent
is that GroupView
var iframes = document.getElementsByTagName("iframe");
for(var i = 0, len = iframes.length; i<len; i++){
window.frames[i].onload = function(_i){
return function(){
iframes[_i].style.height = window.frames[_i].document.body.scrollHeight + "px";
}
}(i);
}
This can be done fairly easily with SyntaxHighlighter. I have step-by-step instructions for setting up SyntaxHighlighter in Blogger on my blog. SyntaxHighlighter is very easy to use. It lets you post snippets in raw form and then wrap them in pre
blocks like:
<pre name="code" class="brush: erlang"><![CDATA[
-module(trim).
-export([string_strip_right/1, reverse_tl_reverse/1, bench/0]).
bench() -> [nbench(N) || N <- [1,1000,1000000]].
nbench(N) -> {N, bench(["a" || _ <- lists:seq(1,N)])}.
bench(String) ->
{{string_strip_right,
lists:sum([
element(1, timer:tc(trim, string_strip_right, [String]))
|| _ <- lists:seq(1,1000)])},
{reverse_tl_reverse,
lists:sum([
element(1, timer:tc(trim, reverse_tl_reverse, [String]))
|| _ <- lists:seq(1,1000)])}}.
string_strip_right(String) -> string:strip(String, right, $\n).
reverse_tl_reverse(String) ->
lists:reverse(tl(lists:reverse(String))).
]]></pre>
Just change the brush name to "python" or "java" or "javascript" and paste in the code of your choice. The CDATA tagging let's you put pretty much any code in there without worrying about entity escaping or other typical annoyances of code blogging.
Yes, I got the answer.. just simply edit the manifest
file as:
<activity android:name=".MainActivity"
android:label="@string/app_name"
android:windowSoftInputMode="stateAlwaysVisible" />
and set EditText.requestFocus()
in onCreate()
..
Thanks..

Based on the @Jodiug comment if you have a 1.15
version you can use the command:
kubectl rollout restart deployment/demo
Read more on the issue:

Well there is an interesting discussion about this subject on the kubernetes GitHub project. See the issue: https://github.com/kubernetes/kubernetes/issues/33664
From the solutions described there, I would suggest one of two.
1.Prepare deployment
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: demo
spec:
replicas: 1
template:
metadata:
labels:
app: demo
spec:
containers:
- name: demo
image: registry.example.com/apps/demo:master
imagePullPolicy: Always
env:
- name: FOR_GODS_SAKE_PLEASE_REDEPLOY
value: 'THIS_STRING_IS_REPLACED_DURING_BUILD'
2.Deploy
sed -ie "s/THIS_STRING_IS_REPLACED_DURING_BUILD/$(date)/g" deployment.yml
kubectl apply -f deployment.yml
kubectl patch deployment web -p \
"{\"spec\":{\"template\":{\"metadata\":{\"labels\":{\"date\":\"`date +'%s'`\"}}}}}"
Of course the imagePullPolicy: Always
is required on both cases.
