I know it's an old question but today got the same error and non of the above solutions worked.
Have fixed it however by setting option:
Project -> Architecture -> Build Active Architecture Only
to Yes
and project compiles and builds properly
I wanted to detect for the presence of .NET version 4.5.2 installed on my system, and I found no better solution than ASoft .NET Version Detector.
Snapshot of this tool showing different .NET versions:
The caller-saved / callee-saved terminology is based on a pretty braindead inefficient model of programming where callers actually do save/restore all the call-clobbered registers (instead of keeping long-term-useful values elsewhere), and callees actually do save/restore all the call-preserved registers (instead of just not using some or any of them).
Or you have to understand that "caller-saved" means "saved somehow if you want the value later".
In reality, efficient code lets values get destroyed when they're no longer needed. Compilers typically make functions that save a few call-preserved registers at the start of a function (and restore them at the end). Inside the function, they use those regs for values that need to survive across function calls.
I prefer "call-preserved" vs. "call-clobbered", which are unambiguous and self-describing once you've heard of the basic concept, and don't require any serious mental gymnastics to think about from the caller's perspective or the callee's perspective. (Both terms are from the same perspective).
Plus, these terms differ by more than one letter.
The terms volatile / non-volatile are pretty good, by analogy with storage which loses its value on power-loss or not, (like DRAM vs. Flash). But the C volatile
keyword has a totally different technical meaning, so that's a downside to "(non)-volatile" when describing C calling conventions.
From the callee's perspective, your function can freely overwrite (aka clobber) these registers without saving/restoring.
From a caller's perspective, call foo
destroys (aka clobbers) all the call-clobbered registers, or at least you have to assume it does.
You can write private helper functions that have a custom calling convention, e.g. you know they don't modify a certain register. But if all you know (or want to assume or depend on) is that the target function follows the normal calling convention, then you have to treat a function call as if it does destroy all the call-clobbered registers. That's literally what the name come from: a call clobbers those registers.
Some compilers that do inter-procedural optimization can also create internal-use-only definitions of functions that don't follow the ABI, using a custom calling convention.
From a callee's perspective, these registers can't be modified unless you save the original value somewhere so you can restore it before returning. Or for registers like the stack pointer (which is almost always call-preserved), you can subtract a known offset and add it back again before returning, instead of actually saving the old value anywhere. i.e. you can restore it by dead reckoning, unless you allocate a runtime-variable amount of stack space. Then typically you restore the stack pointer from another register.
A function that can benefit from using a lot of registers can save/restore some call-preserved registers just so it can use them as more temporaries, even if it doesn't make any function calls. Normally you'd only do this after running out of call-clobbered registers to use, because save/restore typically costs a push/pop at the start/end of the function. (Or if your function has multiple exit paths, a pop
in each of them.)
The name "caller-saved" is misleading: you don't have to specially save/restore them. Normally you arrange your code to have values that need to survive a function call in call-preserved registers, or somewhere on the stack, or somewhere else that you can reload from. It's normal to let a call
destroy temporary values.
See for example What registers are preserved through a linux x86-64 function call for the x86-64 System V ABI.
Also, arg-passing registers are always call-clobbered in all function-calling conventions I'm aware of. See Are rdi and rsi caller saved or callee saved registers?
But system-call calling conventions typically make all the registers except the return value call-preserved. (Usually including even condition-codes / flags.) See What are the calling conventions for UNIX & Linux system calls on i386 and x86-64
If you want result to be stored in another dataset:
df.drop_duplicates(keep=False)
or
df.drop_duplicates(keep=False, inplace=False)
If same dataset needs to be updated:
df.drop_duplicates(keep=False, inplace=True)
Above examples will remove all duplicates and keep one, similar to DISTINCT *
in SQL
Perhaps you may want to consider doing a SELECT max(Id) - min(Id) + 1
. This will only work if your Ids are sequential and rows are not deleted. It is however very fast.
In case that you need to add the http redirect in many sites, you could use it as a c# console program:
class Program
{
static int Main(string[] args)
{
if (args.Length < 3)
{
Console.WriteLine("Please enter an argument: for example insert-redirect ./web.config http://stackoverflow.com");
return 1;
}
if (args.Length == 3)
{
if (args[0].ToLower() == "-insert-redirect")
{
var path = args[1];
var value = args[2];
if (InsertRedirect(path, value))
Console.WriteLine("Redirect added.");
return 0;
}
}
Console.WriteLine("Wrong parameters.");
return 1;
}
static bool InsertRedirect(string path, string value)
{
try
{
XmlDocument doc = new XmlDocument();
doc.Load(path);
// This should find the appSettings node (should be only one):
XmlNode nodeAppSettings = doc.SelectSingleNode("//system.webServer");
var existNode = nodeAppSettings.SelectSingleNode("httpRedirect");
if (existNode != null)
return false;
// Create new <add> node
XmlNode nodeNewKey = doc.CreateElement("httpRedirect");
XmlAttribute attributeEnable = doc.CreateAttribute("enabled");
XmlAttribute attributeDestination = doc.CreateAttribute("destination");
//XmlAttribute attributeResponseStatus = doc.CreateAttribute("httpResponseStatus");
// Assign values to both - the key and the value attributes:
attributeEnable.Value = "true";
attributeDestination.Value = value;
//attributeResponseStatus.Value = "Permanent";
// Add both attributes to the newly created node:
nodeNewKey.Attributes.Append(attributeEnable);
nodeNewKey.Attributes.Append(attributeDestination);
//nodeNewKey.Attributes.Append(attributeResponseStatus);
// Add the node under the
nodeAppSettings.AppendChild(nodeNewKey);
doc.Save(path);
return true;
}
catch (Exception e)
{
Console.WriteLine($"Exception adding redirect: {e.Message}");
return false;
}
}
}
Use the Linux split command:
split -l 20 file.txt new
Split the file "file.txt" into files beginning with the name "new" each containing 20 lines of text each.
Type man split
at the Unix prompt for more information. However you will have to first remove the header from file.txt (using the tail
command, for example) and then add it back on to each of the split files.
$(".testClick").click(function () {
var value = $(this).attr("href");
alert(value );
});
When you use $(".className") you are getting the set of all elements that have that class. Then when you call attr it simply returns the value of the first item in the collection.
You can use Reflections framework for this
import static org.reflections.ReflectionUtils.*;
Set<Method> getters = ReflectionUtils.getAllMethods(someClass,
withModifier(Modifier.PUBLIC), withPrefix("get"), withAnnotation(annotation));
The options object can be added to the chart when the new Chart object is created.
var chart1 = new Chart(canvas, {
type: "pie",
data: data,
options: {
legend: {
display: false
},
tooltips: {
enabled: false
}
}
});
You are right that this has long since been implemented in .NET Core.
At the time of writing (September 2019), the project.json
file of NuGet 3.x+ has been superseded by PackageReference
(as explained at https://docs.microsoft.com/en-us/nuget/archive/project-json).
To get access to the *Async
methods of the HttpClient
class, your .csproj
file must be correctly configured.
Open your .csproj
file in a plain text editor, and make sure the first line is
<Project Sdk="Microsoft.NET.Sdk.Web">
(as pointed out at https://docs.microsoft.com/en-us/dotnet/core/tools/project-json-to-csproj#the-csproj-format).
To get access to the *Async
methods of the HttpClient
class, you also need to have the correct package reference in your .csproj
file, like so:
<ItemGroup>
<!-- ... -->
<PackageReference Include="Microsoft.AspNetCore.App" />
<!-- ... -->
</ItemGroup>
(See https://docs.microsoft.com/en-us/nuget/consume-packages/package-references-in-project-files#adding-a-packagereference. Also: We recommend applications targeting ASP.NET Core 2.1 and later use the Microsoft.AspNetCore.App metapackage, https://docs.microsoft.com/en-us/aspnet/core/fundamentals/metapackage)
Methods such as PostAsJsonAsync
, ReadAsAsync
, PutAsJsonAsync
and DeleteAsync
should now work out of the box. (No using directive needed.)
Update: The PackageReference tag is no longer needed in .NET Core 3.0.
try this:
clients.find{|key,value| value["client_id"] == "2178"}.first
The accepted solution wouldn't work for me as I need a child element with display: inline-block
to be both horizontally and vertically centered within a 100% width parent.
I used Flexbox's justify-content
and align-items
properties, which respectively allow you to center elements horizontally and vertically. By setting both to center
on the parent, the child element (or even multiple elements!) will be perfectly in the middle.
This solution does not require fixed width, which would have been unsuitable for me as my button's text will change.
Here is a CodePen demo and a snippet of the relevant code below:
.parent {
display: flex;
justify-content: center;
align-items: center;
}
_x000D_
<div class="parent">
<a class="child" href="#0">Button</a>
</div>

From plt.imshow()
official guide, we know that aspect controls the aspect ratio of the axes. Well in my words, the aspect is exactly the ratio of x unit and y unit. Most of the time we want to keep it as 1 since we do not want to distort out figures unintentionally. However, there is indeed cases that we need to specify aspect a value other than 1. The questioner provided a good example that x and y axis may have different physical units. Let's assume that x is in km and y in m. Hence for a 10x10 data, the extent should be [0,10km,0,10m] = [0, 10000m, 0, 10m]. In such case, if we continue to use the default aspect=1, the quality of the figure is really bad. We can hence specify aspect = 1000 to optimize our figure. The following codes illustrate this method.
%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt
rng=np.random.RandomState(0)
data=rng.randn(10,10)
plt.imshow(data, origin = 'lower', extent = [0, 10000, 0, 10], aspect = 1000)
Nevertheless, I think there is an alternative that can meet the questioner's demand. We can just set the extent as [0,10,0,10] and add additional xy axis labels to denote the units. Codes as follows.
plt.imshow(data, origin = 'lower', extent = [0, 10, 0, 10])
plt.xlabel('km')
plt.ylabel('m')
To make a correct figure, we should always bear in mind that x_max-x_min = x_res * data.shape[1]
and y_max - y_min = y_res * data.shape[0]
, where extent = [x_min, x_max, y_min, y_max]
. By default, aspect = 1
, meaning that the unit pixel is square. This default behavior also works fine for x_res and y_res that have different values. Extending the previous example, let's assume that x_res is 1.5 while y_res is 1. Hence extent should equal to [0,15,0,10]. Using the default aspect, we can have rectangular color pixels, whereas the unit pixel is still square!
plt.imshow(data, origin = 'lower', extent = [0, 15, 0, 10])
# Or we have similar x_max and y_max but different data.shape, leading to different color pixel res.
data=rng.randn(10,5)
plt.imshow(data, origin = 'lower', extent = [0, 5, 0, 5])
The aspect of color pixel is x_res / y_res
. setting its aspect to the aspect of unit pixel (i.e. aspect = x_res / y_res = ((x_max - x_min) / data.shape[1]) / ((y_max - y_min) / data.shape[0])
) would always give square color pixel. We can change aspect = 1.5 so that x-axis unit is 1.5 times y-axis unit, leading to a square color pixel and square whole figure but rectangular pixel unit. Apparently, it is not normally accepted.
data=rng.randn(10,10)
plt.imshow(data, origin = 'lower', extent = [0, 15, 0, 10], aspect = 1.5)
The most undesired case is that set aspect an arbitrary value, like 1.2, which will lead to neither square unit pixels nor square color pixels.
plt.imshow(data, origin = 'lower', extent = [0, 15, 0, 10], aspect = 1.2)
Long story short, it is always enough to set the correct extent and let the matplotlib do the remaining things for us (even though x_res!=y_res)! Change aspect only when it is a must.
You need to change the constructor of the child
class to this:
public child(int i) : base(i)
{
Console.WriteLine("child");
}
The part : base(i)
means that the constructor of the base class with one int
parameter should be used. If this is missing, you are implicitly telling the compiler to use the default constructor without parameters. Because no such constructor exists in the base class it is giving you this error.
If you want to change the referer (url) header that will be sent to the server when a user clicks an anchor or iframe is opened, you can do it without any hacks. Simply do history.replaceState, you will change the url as it will appear in the browser bar and also the referer that will be send to the server.
I had a similar problem quite recently. In my case:
I downloaded an artifact from some less popular Maven repo
This repo dissappeared over this year
Now builds fail, even if I have this artifact and its pom.xml in my local repo
Workaround:
delete _remote.repositories file in your local repo, where this artifact resides. Now the project builds.
#!/bin/bash
for i in $(seq 1 2 10)
do
echo "skip by 2 value $i"
done
How about this...
<style type="text/css">
div.frame { background-color: #000; }
img.pic:hover {
opacity: .6;
filter:alpha(opacity=60);
}
</style>
<div class="frame">
<img class="pic" src="path/to/image" />
</div>
if you want to access table cell
WebElement thirdCell = driver.findElement(By.Xpath("//table/tbody/tr[2]/td[1]"));

If you're using Node.js, you're sure to have EcmaScript 5, and so Date has a toISOString
method. You're asking for a slight modification of ISO8601:
new Date().toISOString()
> '2012-11-04T14:51:06.157Z'
So just cut a few things out, and you're set:
new Date().toISOString().
replace(/T/, ' '). // replace T with a space
replace(/\..+/, '') // delete the dot and everything after
> '2012-11-04 14:55:45'
Or, in one line: new Date().toISOString().replace(/T/, ' ').replace(/\..+/, '')
ISO8601 is necessarily UTC (also indicated by the trailing Z on the first result), so you get UTC by default (always a good thing).
Assign fx:id or declare variable to/of any node: anchorpane, button, etc. Then add event handler to it and within that event handler insert the given code below:
Stage stage = (Stage)((Node)((EventObject) eventVariable).getSource()).getScene().getWindow();
Hope, this works for you!!
All the other codes I've tested didn't work good due to the fact that the user could still place the caret/cursor wherever in the middle of the string (ex.: 12|3.00 - where | is the cursor). My solution always puts the cursor in the end of the string whenever the touch occurs on the EditText.
The ultimate solution is:
// For a EditText like:
<EditText
android:id="@+id/EditTextAmount"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:hint="@string/amount"
android:layout_weight="1"
android:text="@string/zero_value"
android:inputType="text|numberDecimal"
android:maxLength="13"/>
@string/amount="0.00" @string/zero_value="0.00"
// Create a Static boolean flag
private static boolean returnNext;
// Set caret/cursor to the end on focus change
EditTextAmount.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View editText, boolean hasFocus) {
if(hasFocus){
((EditText) editText).setSelection(((EditText) editText).getText().length());
}
}
});
// Create a touch listener and put caret to the end (no matter where the user touched in the middle of the string)
EditTextAmount.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View editText, MotionEvent event) {
((EditText) editText).onTouchEvent(event);
((EditText) editText).setSelection(((EditText) editText).getText().length());
return true;
}
});
// Implement a Currency Mask with addTextChangedListener
EditTextAmount.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
String input = s.toString();
String output = new String();
String buffer = new String();
String decimals = new String();
String numbers = Integer.toString(Integer.parseInt(input.replaceAll("[^0-9]", "")));
if(returnNext){
returnNext = false;
return;
}
returnNext = true;
if (numbers.equals("0")){
output += "0.00";
}
else if (numbers.length() <= 2){
output += "0." + String.format("%02d", Integer.parseInt(numbers));
}
else if(numbers.length() >= 3){
decimals = numbers.substring(numbers.length() - 2);
int commaCounter = 0;
for(int i=numbers.length()-3; i>=0; i--){
if(commaCounter == 3){
buffer += ",";
commaCounter = 0;
}
buffer += numbers.charAt(i);
commaCounter++;
}
output = new StringBuilder(buffer).reverse().toString() + "." + decimals;
}
EditTextAmount.setText(output);
EditTextAmount.setSelection(EditTextAmount.getText().length());
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
/*String input = s.toString();
if(input.equals("0.0")){
EditTextAmount.setText("0.00");
EditTextAmount.setSelection(EditTextAmount.getText().length());
return;
}*/
}
@Override
public void afterTextChanged(Editable s) {
}
});
Hope it helps!
You can have a constructor in the abstract class that accepts the init parameters. The Java spec only specifies that the anonymous class, which is the offspring of the (optionally) abstract class or implementation of an interface, can not have a constructor by her own right.
The following is absolutely legal and possible:
static abstract class Q{
int z;
Q(int z){ this.z=z;}
void h(){
Q me = new Q(1) {
};
}
}
If you have the possibility to write the abstract class yourself, put such a constructor there and use fluent API where there is no better solution. You can this way override the constructor of your original class creating an named sibling class with a constructor with parameters and use that to instantiate your anonymous class.
Using the spread operator:
const result = arr.reduce(
(accumulator, target) => ({ ...accumulator, [target.key]: target.val }),
{});

If you're happy not not supporting IE or pre-Chromium Edge (which might be fine if you are using this for progressive enhancement), you can use :placeholder-shown
as Berend has said. Note that for Chrome and Safari you actually need a non-empty placeholder for this to work, though a space works.

If you just want to tack something on by hand, then the sed
answer will work for you. If instead the text is in file(s) (say file1.txt and file2.txt):
Using Perl:
perl -e 'open(OUT, ">>", "outfile.txt"); print OUT while (<>);' file*.txt
N.B. while the >>
may look like an indication of redirection, it is just the file open mode, in this case "append".
It's simple, use $.getJSON()

The SimpleNamespace
class could be used to create new attributes with setattr
, or subclass SimpleNamespace
and create your own function to add new attribute names (variables).
from types import SimpleNamespace
variables = {"b":"B","c":"C"}
a = SimpleNamespace(**variables)
setattr(a,"g","G")
a.g = "G+"
something = a.a
If you insist on using GL, you could render the text on to textures. Assuming that most of the HUD is relatively static, you shouldn't have to load the textures to texture memory too often.
In simple terms, it tells the compiler not to do any optimisation on a particular variable. Variables which are mapped to device register are modified indirectly by the device. In this case, volatile must be used.
You can easily launch a market link or an install prompt:
Intent promptInstall = new Intent(Intent.ACTION_VIEW)
.setDataAndType(Uri.parse("file:///path/to/your.apk"),
"application/vnd.android.package-archive");
startActivity(promptInstall);
Intent goToMarket = new Intent(Intent.ACTION_VIEW)
.setData(Uri.parse("market://details?id=com.package.name"));
startActivity(goToMarket);
However, you cannot install .apks without user's explicit permission; not unless the device and your program is rooted.

Either use one of the standard date and time format strings which only specifies the date (e.g. "D" or "d"), or a custom date and time format string which only uses the date parts (e.g. "yyyy/MM/dd").
Type-check with the -is operator returns false for any null value. In most cases, if not all, $value -is [System.Object] will be true for any possible non-null value. (In all cases, it will be false for any null-value.)
My value is nothing if not an object.

If you have your navigation <ul>
with class #nav
Then you need to put that <ul>
item within a div container. Make your div container the 100% width. and set the text-align: element to center in the div container. Then in your <ul>
set that class to have 3 particular elements: text-align:center; position: relative; and display: inline-block;
that should center it.
I just added H:i:s to Rocket's answer to get the time along with the date.

I had trouble initially (don't know why) but I finally got the following to work with SSMS for SQL Server 2008.
Insert ALT-13 then ALT-10 where desired in your text in a varchar type column (music symbol and square appear and save when you leave the row). Initially you'll get a warning(!) to the left of the row after leaving it. Just re-excecute your SELECT statement. The symbols and warning will disappear but the CR/LF is saved. You must include ALT-13 if you want the text displayed properly in HTML. To quickly determine if this worked, copy the saved text from SSMS to Notepad.
Alternatively, if you can't get this to work, you can do the same thing starting with an nvarchar column. However the symbols will be saved as text so you must convert the column to varchar when you're done to convert the symbols to CR/LFs.
If you want to copy & paste text from another source (another row or table, HTML, Notepad, etc.) and not have your text truncated at the first CR, I found that the solution (Programmer's Notepad) referred to at the following link works with SSMS for SQL Server 2008 using varchar & nvarchar column types.
The author of the post (dbaspot) mentions something about creating SQL queries - not sure what he means. Just follow the intructions about Programmer's Notepad and you can copy & paste text to and from SSMS and retain the LFs both ways (using Programmer's Notepad, not Notepad). To have the text display properly in HTML you must add CRs to the text copied to SSMS. The best way to do this is by executing an UPDATE statement using the REPLACE function to add CRs as follows:
UPDATE table_name
SET column_name = REPLACE(column_name , CHAR(10), CHAR(13) + CHAR(10)).
Set the position to absolute; to move the caption area in the correct position
CSS
.post-content {
background: none repeat scroll 0 0 #FFFFFF;
opacity: 0.5;
margin: -54px 20px 12px;
position: absolute;
}
You could create a DataView object from your datasource. This would allow you to filter and sort your data without directly modifying the datasource.
Also, remember to call dataGridView1.DataBind();
after you set the data source.
They are bit shift operator which exists in many mainstream programming languages, <<
is the left shift and >>
is the right shift, they can be demonstrated as the following table, assume an integer only take 1 byte in memory.
| operate | bit value | octal value | description |
| ------- | --------- | ----------- | -------------------------------------------------------- |
| | 00000100 | 4 | |
| 4 << 2 | 00010000 | 16 | move all bits to left 2 bits, filled with 0 at the right |
| 16 >> 2 | 00000100 | 4 | move all bits to right 2 bits, filled with 0 at the left |
use
SELECT DISTINCT Date FROM buy ORDER BY Date
so MySQL removes duplicates
BTW: using explicit column names in SELECT
uses less resources in PHP when you're getting a large result from MySQL
I came researching the options that I would have to do this, however, I believe the method I use is the simplest:
SELECT COUNT(*),
DATEADD(dd, DATEDIFF(dd, 0, date_field),0) as dtgroup
FROM TABLE
GROUP BY DATEADD(dd, DATEDIFF(dd, 0, date_field),0)
ORDER BY dtgroup ASC;
Concat
returns a new sequence without modifying the original list. Try myList1.AddRange(myList2)
.
You can't do it because you can't have control on the manner Chrome opens its windows
First, disable the php5
module:
a2dismod php5
then, enable the php7
module:
a2enmod php7.0
Next, reload/restart the Apache service:
service apache2 restart
wrt the comment, you need to specify exact installed php-7.x version.
You can easily do this by:
::variableName.isInitialized
or
this::variableName.isInitialized
But if you are inside a listener or inner class, do this:
this@OuterClassName::variableName.isInitialized
Note: The above statements work fine if you are writing them in the same file(same class or inner class) where the variable is declared but this will not work if you want to check the variable of other class (which could be a superclass or any other class which is instantiated), for ex:
class Test {
lateinit var str:String
}
And to check if str is initialized:
What we are doing here: checking isInitialized
for field str
of Test
class in Test2
class.
And we get an error backing field of var is not accessible at this point.
Check a question already raised about this.
var x : IHash = {};
x['key1'] = 'value1';
x['key2'] = 'value2';
console.log(x['key1']);
// outputs value1
console.log(x['key2']);
// outputs value2
If you would like to then iterate through your dictionary, you can use.
Object.keys(x).forEach((key) => {console.log(x[key])});
Object.keys returns all the properties of an object, so it works nicely for returning all the values from dictionary styled objects.
You also mentioned a hashmap in your question, the above definition is for a dictionary style interface. Therefore the keys will be unique, but the values will not.
You could use it like a hashset by just assigning the same value to the key and its value.
if you wanted the keys to be unique and with potentially different values, then you just have to check if the key exists on the object before adding to it.
var valueToAdd = 'one';
if(!x[valueToAdd])
x[valueToAdd] = valueToAdd;
or you could build your own class to act as a hashset of sorts.
Class HashSet{
private var keys: IHash = {};
private var values: string[] = [];
public Add(key: string){
if(!keys[key]){
values.push(key);
keys[key] = key;
}
}
public GetValues(){
// slicing the array will return it by value so users cannot accidentally
// start playing around with your array
return values.slice();
}
}
I was attempting to find strings with numbers ONLY, no punctuation or anything else. I finally found an answer that would work here.
Using PATINDEX('%[^0-9]%', some_column) = 0 allowed me to filter out everything but actual number strings.
You're not going to be able to modify the caller's shell because it's in a different process context. When child processes inherit your shell's variables, they're inheriting copies themselves.
One thing you can do is to write a script that emits the correct commands for tcsh or sh based how it's invoked. If you're script is "setit" then do:
ln -s setit setit-sh
and
ln -s setit setit-csh
Now either directly or in an alias, you do this from sh
eval `setit-sh`
or this from csh
eval `setit-csh`
setit uses $0 to determine its output style.
This is reminescent of how people use to get the TERM environment variable set.
The advantage here is that setit is just written in whichever shell you like as in:
#!/bin/bash
arg0=$0
arg0=${arg0##*/}
for nv in \
NAME1=VALUE1 \
NAME2=VALUE2
do
if [ x$arg0 = xsetit-sh ]; then
echo 'export '$nv' ;'
elif [ x$arg0 = xsetit-csh ]; then
echo 'setenv '${nv%%=*}' '${nv##*=}' ;'
fi
done
with the symbolic links given above, and the eval of the backquoted expression, this has the desired result.
To simplify invocation for csh, tcsh, or similar shells:
alias dosetit 'eval `setit-csh`'
or for sh, bash, and the like:
alias dosetit='eval `setit-sh`'
One nice thing about this is that you only have to maintain the list in one place.
In theory you could even stick the list in a file and put cat nvpairfilename
between "in" and "do".
This is pretty much how login shell terminal settings used to be done: a script would output statments to be executed in the login shell. An alias would generally be used to make invocation simple, as in "tset vt100". As mentioned in another answer, there is also similar functionality in the INN UseNet news server.
Exporting all collections using mongodump use the following command
mongodump -d database_name -o directory_to_store_dumps
To restore use this command
mongorestore -d database_name directory_backup_where_mongodb_tobe_restored
The easiest way to do this is:
String hexadecimalString = String.format("%x", integerValue);
The important thing about fft is that it can only be applied to data in which the timestamp is uniform (i.e. uniform sampling in time, like what you have shown above).
In case of non-uniform sampling, please use a function for fitting the data. There are several tutorials and functions to choose from:
https://github.com/tiagopereira/python_tips/wiki/Scipy%3A-curve-fitting http://docs.scipy.org/doc/numpy/reference/generated/numpy.polyfit.html
If fitting is not an option, you can directly use some form of interpolation to interpolate data to a uniform sampling:
https://docs.scipy.org/doc/scipy-0.14.0/reference/tutorial/interpolate.html
When you have uniform samples, you will only have to wory about the time delta (t[1] - t[0]
) of your samples. In this case, you can directly use the fft functions
Y = numpy.fft.fft(y)
freq = numpy.fft.fftfreq(len(y), t[1] - t[0])
pylab.figure()
pylab.plot( freq, numpy.abs(Y) )
pylab.figure()
pylab.plot(freq, numpy.angle(Y) )
pylab.show()
This should solve your problem.

The proper answer to your question is to use statistics.mean
. But for fun, here is a version of mean that does not use the len()
function, so it (like statistics.mean
) can be used on generators, which do not support len()
:
from functools import reduce
from operator import truediv
def ave(seq):
return truediv(*reduce(lambda a, b: (a[0] + b[1], b[0]),
enumerate(seq, start=1),
(0, 0)))
import os
path = chap_name
if not os.path.exists(path):
os.makedirs(path)
filename = img_alt + '.jpg'
with open(os.path.join(path, filename), 'wb') as temp_file:
temp_file.write(buff)
Key point is to use os.makedirs
in place of os.mkdir
. It is recursive, i.e. it generates all intermediate directories. See http://docs.python.org/library/os.html
Open the file in binary mode as you are storing binary (jpeg) data.
In response to Edit 2, if img_alt sometimes has '/' in it:
img_alt = os.path.basename(img_alt)
Let's take a simple example. Let's say two tables named test
and customer
are there described as:
create table test(
test_id int(11) not null auto_increment,
primary key(test_id));
create table customer(
customer_id int(11) not null auto_increment,
name varchar(50) not null,
primary key(customer_id));
One more table is there which keeps the track of test
s and customer
:
create table tests_purchased(
customer_id int(11) not null,
test_id int(11) not null,
created_date datetime not null,
primary key(customer_id, test_id));
We can see that in the table tests_purchased
the primary key is a composite key, so we will use the <composite-id ...>...</composite-id>
tag in the hbm.xml
mapping file. So the PurchasedTest.hbm.xml
will look like:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="entities.PurchasedTest" table="tests_purchased">
<composite-id name="purchasedTestId">
<key-property name="testId" column="TEST_ID" />
<key-property name="customerId" column="CUSTOMER_ID" />
</composite-id>
<property name="purchaseDate" type="timestamp">
<column name="created_date" />
</property>
</class>
</hibernate-mapping>
But it doesn't end here. In Hibernate we use session.load (entityClass
, id_type_object
) to find and load the entity using primary key. In case of composite keys, the ID object should be a separate ID class (in above case a PurchasedTestId
class) which just declares the primary key attributes like below:
import java.io.Serializable;
public class PurchasedTestId implements Serializable {
private Long testId;
private Long customerId;
// an easy initializing constructor
public PurchasedTestId(Long testId, Long customerId) {
this.testId = testId;
this.customerId = customerId;
}
public Long getTestId() {
return testId;
}
public void setTestId(Long testId) {
this.testId = testId;
}
public Long getCustomerId() {
return customerId;
}
public void setCustomerId(Long customerId) {
this.customerId = customerId;
}
@Override
public boolean equals(Object arg0) {
if(arg0 == null) return false;
if(!(arg0 instanceof PurchasedTestId)) return false;
PurchasedTestId arg1 = (PurchasedTestId) arg0;
return (this.testId.longValue() == arg1.getTestId().longValue()) &&
(this.customerId.longValue() == arg1.getCustomerId().longValue());
}
@Override
public int hashCode() {
int hsCode;
hsCode = testId.hashCode();
hsCode = 19 * hsCode+ customerId.hashCode();
return hsCode;
}
}
Important point is that we also implement the two functions hashCode()
and equals()
as Hibernate relies on them.
I need to save the phone's timezone in the format [+/-]hh:mm
No, you don't. Offset on its own is not enough, you need to store the whole time zone name/id. For example I live in Oslo where my current offset is +02:00 but in winter (due to dst) it is +01:00. The exact switch between standard and summer time depends on factors you don't want to explore.
So instead of storing + 02:00
(or should it be + 01:00
?) I store "Europe/Oslo"
in my database. Now I can restore full configuration using:
TimeZone tz = TimeZone.getTimeZone("Europe/Oslo")
Want to know what is my time zone offset today?
tz.getOffset(new Date().getTime()) / 1000 / 60 //yields +120 minutes
However the same in December:
Calendar christmas = new GregorianCalendar(2012, DECEMBER, 25);
tz.getOffset(christmas.getTimeInMillis()) / 1000 / 60 //yields +60 minutes
Enough to say: store time zone name or id and every time you want to display a date, check what is the current offset (today) rather than storing fixed value. You can use TimeZone.getAvailableIDs()
to enumerate all supported timezone IDs.
I generally like to merge master
into the development
first so that if there are any conflicts, I can resolve in the development
branch itself and my master
remains clean.
(on branch development)$ git merge master
(resolve any merge conflicts if there are any)
git checkout master
git merge development (there won't be any conflicts now)
There isn't much of a difference in the two approaches, but I have noticed sometimes that I don't want to merge the branch into master
yet, after merging them, or that there is still more work to be done before these can be merged, so I tend to leave master
untouched until final stuff.
EDIT: From comments
If you want to keep track of who did the merge and when, you can use --no-ff
flag while merging to do so. This is generally useful only when merging development
into the master
(last step), because you might need to merge master
into development
(first step) multiple times in your workflow, and creating a commit node for these might not be very useful.
git merge --no-ff development
Set all the column's (which can be sortable by users) SortMode property to Automatic
dataGridView1.DataSource = students.Select(s => new { ID = s.StudentId, RUDE = s.RUDE, Nombre = s.Name, Apellidos = s.LastNameFather + " " + s.LastNameMother, Nacido = s.DateOfBirth })
.OrderBy(s => s.Apellidos)
.ToList();
foreach(DataGridViewColumn column in dataGridView1.Columns)
{
column.SortMode = DataGridViewColumnSortMode.Automatic;
}
Edit: As your datagridview is bound with a linq query, it will not be sorted. So please go through this [404 dead link, see next section]
which explains how to create a sortable binding list and to then feed it as datasource to datagridview.
Link from above is 404-dead. I recovered the code from the Internet Wayback Machine archive of the page.
public Form1()
{
InitializeComponent();
SortableBindingList<person> persons = new SortableBindingList<person>();
persons.Add(new Person(1, "timvw", new DateTime(1980, 04, 30)));
persons.Add(new Person(2, "John Doe", DateTime.Now));
this.dataGridView1.AutoGenerateColumns = false;
this.ColumnId.DataPropertyName = "Id";
this.ColumnName.DataPropertyName = "Name";
this.ColumnBirthday.DataPropertyName = "Birthday";
this.dataGridView1.DataSource = persons;
}
Windows PowerShell provides two mechanisms for reporting errors: one mechanism for terminating errors and another mechanism for non-terminating errors.
Internal CmdLets code can call a ThrowTerminatingError
method when an error occurs that does not or should not allow the cmdlet to continue to process its input objects. The script writter can them use exception to catch these error.
EX :
try
{
Your database code
}
catch
{
Error reporting/logging
}
Internal CmdLets code can call a WriteError
method to report non-terminating errors when the cmdlet can continue processing the input objects. The script writer can then use -ErrorAction option to hide the messages, or use the $ErrorActionPreference
to setup the entire script behaviour.
On which point does HTTPURLConnection try to establish a connection to the given URL?
It's worth clarifying, there's the 'UrlConnection' instance and then there's the underlying Tcp/Ip/SSL socket connection, 2 different concepts. The 'UrlConnection' or 'HttpUrlConnection' instance is synonymous with a single HTTP page request, and is created when you call url.openConnection(). But if you do multiple url.openConnection()'s from the one 'url' instance then if you're lucky, they'll reuse the same Tcp/Ip socket and SSL handshaking stuff...which is good if you're doing lots of page requests to the same server, especially good if you're using SSL where the overhead of establishing the socket is very high.
Well, the main reason would be for separating the interface from the implementation. The header declares "what" a class (or whatever is being implemented) will do, while the cpp file defines "how" it will perform those features.
This reduces dependencies so that code that uses the header doesn't necessarily need to know all the details of the implementation and any other classes/headers needed only for that. This will reduce compilation times and also the amount of recompilation needed when something in the implementation changes.
It's not perfect, and you would usually resort to techniques like the Pimpl Idiom to properly separate interface and implementation, but it's a good start.
You can connect to a AWS ec-2 instance using the following commands.
chmod 400 mykey.pem
ssh -i mykey.pem username@your-ip
by default the machine name usually be like ubuntu since usually ubuntu machine is used as a server so the following command will work in that case.
ssh -i mykey.pem ubuntu@your-ip

Perfectly described here https://www.smashingmagazine.com/2014/05/moving-git-repository-new-server/
First, we have to fetch all of the remote branches and tags from the existing repository to our local index:
git fetch origin
We can check for any missing branches that we need to create a local copy of:
git branch -a
Let’s use the SSH-cloned URL of our new repository to create a new remote in our existing local repository:
git remote add new-origin [email protected]:manakor/manascope.git
Now we are ready to push all local branches and tags to the new remote named new-origin:
git push --all new-origin
git push --tags new-origin
Let’s make new-origin the default remote:
git remote rm origin
Rename new-origin to just origin, so that it becomes the default remote:
git remote rename new-origin origin
the trick is with outline property thanks to enigment's answer with little modification
use this class
.row-border{
outline: thin solid black;
outline-offset: -1px;
}
then in the HTML
<tr>....</tr>
<tr class="row-border">
<td>...</td>
<td>...</td>
</tr>
You could set an interceptor "ClientHttpRequestInterceptor" in your RestTemplate to avoid setting the header every time you send a request.
public class HeaderRequestInterceptor implements ClientHttpRequestInterceptor {
private final String headerName;
private final String headerValue;
public HeaderRequestInterceptor(String headerName, String headerValue) {
this.headerName = headerName;
this.headerValue = headerValue;
}
@Override
public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution) throws IOException {
request.getHeaders().set(headerName, headerValue);
return execution.execute(request, body);
}
}
Then
List<ClientHttpRequestInterceptor> interceptors = new ArrayList<ClientHttpRequestInterceptor>();
interceptors.add(new HeaderRequestInterceptor("Accept", MediaType.APPLICATION_JSON_VALUE));
RestTemplate restTemplate = new RestTemplate();
restTemplate.setInterceptors(interceptors);
The object can be used as a parameter in Exception.with_traceback()
function:
except Exception as e:
tb = sys.exc_info()
print(e.with_traceback(tb[2]))
Somewhat dated question, but maybe still useful: you may take a look at FusionCache ?, which I recently released.
The feature you are looking for is described here, and you can use it like this:
const string CacheKey = "CacheKey";
static string GetCachedData()
{
return fusionCache.GetOrSet(
CacheKey,
_ => SomeHeavyAndExpensiveCalculation(),
TimeSpan.FromMinutes(20)
);
}
You may also find some of the other features interesting like fail-safe, advanced timeouts with background factory completion and support for an optional, distributed 2nd level cache.
If you will give it a chance please let me know what you think.

If you're not in an ipython notebook (like the OP), you can also just declare the size when you declare the figure:
width = 12
height = 12
plt.figure(figsize=(width, height))
//Your Abstract class Animal
function Animal(type) {
this.say = type.say;
}
function catClass() {
this.say = function () {
console.log("I am a cat!")
}
}
function dogClass() {
this.say = function () {
console.log("I am a dog!")
}
}
var cat = new Animal(new catClass());
var dog = new Animal(new dogClass());
cat.say(); //I am a cat!
dog.say(); //I am a dog!
For all struggling around with the #selector in Swift 3 or Swift 4, here a full code example:
// WE NEED A CLASS THAT SHOULD RECEIVE NOTIFICATIONS
class MyReceivingClass {
// ---------------------------------------------
// INIT -> GOOD PLACE FOR REGISTERING
// ---------------------------------------------
init() {
// WE REGISTER FOR SYSTEM NOTIFICATION (APP WILL RESIGN ACTIVE)
// Register without parameter
NotificationCenter.default.addObserver(self, selector: #selector(MyReceivingClass.handleNotification), name: .UIApplicationWillResignActive, object: nil)
// Register WITH parameter
NotificationCenter.default.addObserver(self, selector: #selector(MyReceivingClass.handle(withNotification:)), name: .UIApplicationWillResignActive, object: nil)
}
// ---------------------------------------------
// DE-INIT -> LAST OPTION FOR RE-REGISTERING
// ---------------------------------------------
deinit {
NotificationCenter.default.removeObserver(self)
}
// either "MyReceivingClass" must be a subclass of NSObject OR selector-methods MUST BE signed with '@objc'
// ---------------------------------------------
// HANDLE NOTIFICATION WITHOUT PARAMETER
// ---------------------------------------------
@objc func handleNotification() {
print("RECEIVED ANY NOTIFICATION")
}
// ---------------------------------------------
// HANDLE NOTIFICATION WITH PARAMETER
// ---------------------------------------------
@objc func handle(withNotification notification : NSNotification) {
print("RECEIVED SPECIFIC NOTIFICATION: \(notification)")
}
}
In this example we try to get POSTs from AppDelegate (so in AppDelegate implement this):
// ---------------------------------------------
// WHEN APP IS GOING TO BE INACTIVE
// ---------------------------------------------
func applicationWillResignActive(_ application: UIApplication) {
print("POSTING")
// Define identifiyer
let notificationName = Notification.Name.UIApplicationWillResignActive
// Post notification
NotificationCenter.default.post(name: notificationName, object: nil)
}

You never named your submit button, so as far as the form is concerned it's just an action.
Either:
<input type="submit" name="submit" ... />
)if (!empty($_POST))
instead to detect when data has been posted.Remember that keys in the $_POST
superglobal only appear for named input elements. So, unless the element has the name attribute, it won't come through to $_POST
(or $_GET
/$_REQUEST
)
The transmission delay is the amount of time required for the router to push out the packet.
The propagation delay, is the time it takes a bit to propagate from one router to the next.
the transmission and propagation delay are completely different! if denote the length of the packet by L bits, and denote the transmission rate of the link from first router to second router by R bits/sec. then transmission delay will be L/R. and this is depended to transmission rate of link and the length of packet.
then if denote the distance between two routers d and denote the propagation speed s, the propagation delay will be d/s. it is a function of the Distance between the two routers, but has no dependence to the packet's length or the transmission rate of the link.
Setters and Getters apply to computed properties
; such properties do not have storage in the instance - the value from the getter is meant to be computed from other instance properties. In your case, there is no x
to be assigned.
Explicitly: "How can I do this without explicit backing ivars". You can't - you'll need something to backup the computed property. Try this:
class Point {
private var _x: Int = 0 // _x -> backingX
var x: Int {
set { _x = 2 * newValue }
get { return _x / 2 }
}
}
Specifically, in the Swift REPL:
15> var pt = Point()
pt: Point = {
_x = 0
}
16> pt.x = 10
17> pt
$R3: Point = {
_x = 20
}
18> pt.x
$R4: Int = 10

You can do this using attribute selectors without introducing the ID and classes but it's slower and (imho) harder to read.
-- Note that you can not use an alias over the table where you need delete
DELETE tbl_pagos_activos_usuario
FROM tbl_pagos_activos_usuario, tbl_usuarios b, tbl_facturas c
Where tbl_pagos_activos_usuario.usuario=b.cedula
and tbl_pagos_activos_usuario.cod=c.cod

Use String.Format()
or TextWriter.Format()
(depending on how you actually write to the file) and specify the width of a field.
String.Format("{0,20}{1,15}{2,15}", "Sample Title One", "Element One", "Whatever Else");
You can specify the width of a field within interpolated strings as well:
$"{"Sample Title One",20}{"Element One",15}{"Whatever Else",15}"
And just so you know, you can create a string of repeated characters using the appropriate string contructor.
new String(' ', 20); // string of 20 spaces
static_cast
means that you can't accidentally const_cast
or reinterpret_cast
, which is a good thing.
For Windows 7 and up, scheduled tasks are not run by cmd.exe
, but rather by MMC
(Microsoft Management Console). %SystemRoot%\Tasks
should work on any other Windows version though.
As an addendum, if you want to reapply your changes on top of the remote, you can also try:
git pull --rebase origin master
If you then want to undo some of your changes (but perhaps not all of them) you can use:
git reset SHA_HASH
Then do some adjustment and recommit.
keytool it's a binary file into the JDK folder ... just add your JDK as environment variable by adding the following line
C:\Program Files\Java\jdk1.8.0_65\bin
This is the simpler and flexible way I found (based on @prunge answer)
Optional<User> user = users.stream()
.filter(user -> user.getId() == 1)
.reduce((a, b) -> {
throw new IllegalStateException("Multiple elements: " + a + ", " + b);
})
This way you obtain:
Optional.empty()
if not presentId be inclined to create classes that match the structure and add an instance to a collection then serialise and deserialise the collection to load and save the document.
Using command line, you can do this:
AT \\computername time "NET STOP servicename"
AT \\computername time "NET START servicename"
Do that like this
db.Users.OrderByDescending(u => u.UserId).FirstOrDefault();
If you're using T-SQL
, the only thing wrong with your code is that you used braces {}
instead of parentheses ()
.
PS: Both IDENTITY
and PRIMARY KEY
imply NOT NULL
, so you can omit that if you wish.
In windows server 2012, even after installing asp.net you might run into this issue.
Check for "Http activation" feature. This feature is present under Web services as well.
Make sure you add the above and everything should be awesome for you !!!
Some options:
tr
tr -d '\15\32' < windows.txt > unix.txt
OR
tr -d '\r' < windows.txt > unix.txt
perl
perl -p -e 's/\r$//' < windows.txt > unix.txt
sed
sed 's/^M$//' windows.txt > unix.txt
OR
sed 's/\r$//' windows.txt > unix.txt
To obtain ^M
, you have to type CTRL-V
and then CTRL-M
.
You could try attaching handlers to various events of BitmapImage:
They might tell you a little about what's going on, as far as the image is concerned.
Most likely it means that the open didn't fail.
When Perl opens a file, it checks whether or not the file is a TTY (so that it can answer the -T $fh
filetest operator) by issuing the TCGETS
ioctl against it. If the file is a regular file and not a tty, the ioctl fails and sets errno to ENOTTY
(string value: "Inappropriate ioctl for device"). As ysth says, the most common reason for seeing an unexpected value in $!
is checking it when it's not valid -- that is, anywhere other than immediately after a syscall failed, so testing the result codes of your operations is critically important.
If open
actually did return false for you, and you found ENOTTY
in $!
then I would consider this a small bug (giving a useless value of $!
) but I would also be very curious as to how it happened. Code and/or truss output would be nifty.
While I agree with Tim and Oben Sonne that you should use an XML library, there are ways to still manipulate it as a simple string object.
I likely would not try to use a single file pointer for what you are describing, and instead read the file into memory, edit it, then write it out.:
inFile = open('file.xml', 'r')
data = inFile.readlines()
inFile.close()
# some manipulation on `data`
outFile = open('file.xml', 'w')
outFile.writelines(data)
outFile.close()
If you are working with anaconda-project, you can query the PROJECT_ROOT from the environment variable --> os.getenv('PROJECT_ROOT'). This works only if the script is executed via anaconda-project run .
If you do not want your script run by anaconda-project, you can query the absolute path of the executable binary of the Python interpreter you are using and extract the path string up to the envs directory exclusiv. For example: The python interpreter of my conda env is located at:
/home/user/project_root/envs/default/bin/python
# You can first retrieve the env variable PROJECT_DIR.
# If not set, get the python interpreter location and strip off the string till envs inclusiv...
if os.getenv('PROJECT_DIR'):
PROJECT_DIR = os.getenv('PROJECT_DIR')
else:
PYTHON_PATH = sys.executable
path_rem = os.path.join('envs', 'default', 'bin', 'python')
PROJECT_DIR = py_path.split(path_rem)[0]
This works only with conda-project with fixed project structure of a anaconda-project
There is very nice tool "Eclipse Quicksearch" available. Checkout SpringSource Update Site for Eclipse i.e: http://dist.springsource.com/release/TOOLS/update/e4.6/ (you can try other versions replacing last part of URL with i.e. e4.4 or e4.5)
It works well with Neon Release (4.6.0). It gives you nice incremental text search with source file preview. I had no issues with it so far.
Usage: Alt + s "Quick Search Command" opens "Quick Text Search" dialog. You can select whether search should be case sensitive or not. Really good tool.
Ok found the answer. exchange()
is the best way. Oddly the HttpEntity
class doesn't have a setBody()
method (it has getBody()
), but it is still possible to set the request body, via the constructor.
// Create the request body as a MultiValueMap
MultiValueMap<String, String> body = new LinkedMultiValueMap<String, String>();
body.add("field", "value");
// Note the body object as first parameter!
HttpEntity<?> httpEntity = new HttpEntity<Object>(body, requestHeaders);
ResponseEntity<MyModel> response = restTemplate.exchange("/api/url", HttpMethod.POST, httpEntity, MyModel.class);
static void Main(string[] args)
{
List<string> listStrings = new List<string>(){ "C#", "Asp.Net", "SQL Server", "PHP", "Angular"};
string CommaSeparateString = GenerateCommaSeparateStringFromList(listStrings);
Console.Write(CommaSeparateString);
Console.ReadKey();
}
private static string GenerateCommaSeparateStringFromList(List<string> listStrings)
{
return String.Join(",", listStrings);
}
As a workaround, go to sdk installation directory and perform the following steps:
system-images/android-19/default
system-images/android-19/
The directory structure should look like this:
And it should work!
You can use array_filter
to filter out elements of an array based on a callback function. The callback function takes each element of the array as an argument and you simply return false
if that element should be removed. This also has the benefit of removing duplicate values since it scans the entire array.
You can use it like this:
$myArray = array('apple', 'orange', 'banana', 'plum', 'banana');
$output = array_filter($myArray, function($value) { return $value !== 'banana'; });
// content of $output after previous line:
// $output = array('apple', 'orange', 'plum');
And if you want to re-index the array, you can pass the result to array_values
like this:
$output = array_values($output);
For me, It was a permission issue. I installed SQL server using a local user account and before joining my companies domain. Later on , I tried to restore a database using my domain account which doesn't have the permissions needed to restore SQL server databases. You need to fix the permission for your domain account and give it system admin permission on the SQL server instance you have.
to_date()
returns a date at 00:00:00, so you need to "remove" the minutes from the date you are comparing to:
select *
from table
where trunc(es_date) = TO_DATE('27-APR-12','dd-MON-yy')
You probably want to create an index on trunc(es_date)
if that is something you are doing on a regular basis.
The literal '27-APR-12'
can fail very easily if the default date format is changed to anything different. So make sure you you always use to_date()
with a proper format mask (or an ANSI literal: date '2012-04-27'
)
Although you did right in using to_date()
and not relying on implict data type conversion, your usage of to_date() still has a subtle pitfall because of the format 'dd-MON-yy'
.
With a different language setting this might easily fail e.g. TO_DATE('27-MAY-12','dd-MON-yy')
when NLS_LANG is set to german. Avoid anything in the format that might be different in a different language. Using a four digit year and only numbers e.g. 'dd-mm-yyyy'
or 'yyyy-mm-dd'
I had the same issue get value for my property in my service class. I resolved it by using @ConfigurationProperties instead of @Value.
import org.springframework.boot.context.properties.ConfigurationProperties;
@ConfigurationProperties(prefix = "file")
public class FileProperties {
private String directory;
public String getDirectory() {
return directory;
}
public void setDirectory(String dir) {
this.directory = dir;
}
}
@EnableConfigurationProperties({
FileProperties.class
})
Native Node.js solution is:
const {execSync} = require('child_process');
const result = execSync('node -v'); // this do the trick
Just be aware that some commands returns Buffer
instead of string
. And if you need string
just add encoding
to execSync options:
const result = execSync('git rev-parse HEAD', {encoding: 'utf8'});
... and it is also good to have timeout on sync exec:
const result = execSync('git rev-parse HEAD', {encoding: 'utf8', timeout: 10000});

How about
a["abc"] = [1, 2]

You can create a temporary parent node, and get the innerHTML content of it:
var el = document.createElement("p");
el.appendChild(document.createTextNode("Test"));
var tmp = document.createElement("div");
tmp.appendChild(el);
console.log(tmp.innerHTML); // <p>Test</p>
EDIT: Please see answer below about outerHTML. el.outerHTML should be all that is needed.

Simple but powerful email validation for check email syntax :
var EmailId = document.getElementById('Email').value;
var emailfilter = /^[\w._-]+[+]?[\w._-]+@[\w.-]+\.[a-zA-Z]{2,6}$/;
if((EmailId != "") && (!(emailfilter.test(EmailId ) ) )) {
msg+= "Enter the valid email address!<br />";
}
In my case, this error message was displayed when I tried downloading an app from Google Play Store using a VPN. The download only worked when I disabled the VPN. Using a VPN, downloads were only working for the apps I downloaded previously.
This looks like a censorship from Google, which is really bad for the user experience and I hope they will stop this.
Fortunately I don't use Android on my smartphone, it was on my Linux laptop using Anbox or Android x86 in VirtualBox.
Be aware, that \W
leaves the underscore. A short equivalent for [^a-zA-Z0-9]
would be [\W_]
text.replace(/[\W_]+/g," ");
\W
is the negation of shorthand \w
for [A-Za-z0-9_]
word characters (including the underscore)
Let's say you have a class ClassA
which contains a method methodA
defined as:
def methodA(self, arg1, arg2):
# do something
and ObjectA
is an instance of this class.
Now when ObjectA.methodA(arg1, arg2)
is called, python internally converts it for you as:
ClassA.methodA(ObjectA, arg1, arg2)
The self
variable refers to the object itself.
Try this one
<?php
$text = "Hello <br /> Hello again <br> Hello again again <br/> Goodbye <BR>";
$breaks = array("<br />","<br>","<br/>");
$text = str_ireplace($breaks, "\r\n", $text);
?>
<textarea><?php echo $text; ?></textarea>
I did it like this
if (document.location.hash != '') {
//get the index from URL hash
var tabSelect = document.location.hash.substr(1, document.location.hash.length);
console.log("tabSelect: " + tabSelect);
if (tabSelect == 'discount')
{
var index = $('#myTab a[href="#discount"]').parent().index();
$("#tabs").tabs("option", "active", index);
$($('#myTab a[href="#discount"]')).tab('show');
}
}
When you are not sure of the number of rows, then you can do it this way:
followers_df.index = range(len(followers_df))
For embedding HTML text in your textview you can use Html.fromHTML()

UPDATE My Answer here is now outdated. The Joda-Time project is now in maintenance mode, advising migration to the java.time classes. See the modern solution in the Answer by Ole V.V..
The accepted answer by NidhishKrishnan is correct.
For fun, here is the same kind of code in Joda-Time 2.3.
// © 2013 Basil Bourque. This source code may be used freely forever by anyone taking full responsibility for doing so.
// import org.joda.time.*;
// import org.joda.time.format.*;
java.util.Date date = new Date(); // A Date object coming from other code.
// Pass the java.util.Date object to constructor of Joda-Time DateTime object.
DateTimeZone kolkataTimeZone = DateTimeZone.forID( "Asia/Kolkata" );
DateTime dateTimeInKolkata = new DateTime( date, kolkataTimeZone );
DateTimeFormatter formatter = DateTimeFormat.forPattern( "yyyy-MM-dd");
System.out.println( "dateTimeInKolkata formatted for date: " + formatter.print( dateTimeInKolkata ) );
System.out.println( "dateTimeInKolkata formatted for ISO 8601: " + dateTimeInKolkata );
When run…
dateTimeInKolkata formatted for date: 2013-12-17
dateTimeInKolkata formatted for ISO 8601: 2013-12-17T14:56:46.658+05:30
the simplest idea is to add pkg-config --cflags --libs sdl2 while compiling the code.
g++ file.cpp `pkg-config --cflags --libs sdl2`
l = [1,2,3,4,5]
sum = 0
for x in l:
sum = sum + x
And you can change l for any list you want.
Actually i am getting return value from a another sp into @temp and then it @temp =1 then i want to inc the count of @SelectoneCount by 1 and so on. Please let me know what is the correct syntax.
What's wrong with:
IF @Temp = 1 --Or @Temp = 2 also?
BEGIN
SET @SelectoneCount = @SelectoneCount + 1
END
(Although this does reek of being procedural code - not usually the best way to use SQL)
Try using an infinite generator.
from itertools import repeat
inputs = (get_input("Is this ok? (y/n)") for _ in repeat(None))
response = (i.lower()=="y" for i in inputs if i.lower() in ("y", "n"))
while True:
#snip: print out current state
if next(response):
break
#do more processing with menus and stuff
Your encoded text is [B@6499375d
. That is not Base64, something went wrong while encoding. That decoding code looks good.
Use this code to convert the byte[] to a String before adding it to the URL:
String encodedEmailString = new String(encodedEmail, "UTF-8");
// ...
String confirmLink = "Complete your registration by clicking on following"
+ "\n<a href='" + confirmationURL + encodedEmailString + "'>link</a>";
By "camera position," it sounds like you want to adjust the elevation and the azimuth angle that you use to view the 3D plot. You can set this with ax.view_init
. I've used the below script to first create the plot, then I determined a good elevation, or elev
, from which to view my plot. I then adjusted the azimuth angle, or azim
, to vary the full 360deg around my plot, saving the figure at each instance (and noting which azimuth angle as I saved the plot). For a more complicated camera pan, you can adjust both the elevation and angle to achieve the desired effect.
from mpl_toolkits.mplot3d import Axes3D
ax = Axes3D(fig)
ax.scatter(xx,yy,zz, marker='o', s=20, c="goldenrod", alpha=0.6)
for ii in xrange(0,360,1):
ax.view_init(elev=10., azim=ii)
savefig("movie%d.png" % ii)

Word Boundary: \b*
The word boundary \b matches positions where one side is a word character (usually a letter, digit or underscore—but see below for variations across engines) and the other side is not a word character (for instance, it may be the beginning of the string or a space character).
The regex \bcat\b would, therefore, match cat in a black cat, but it wouldn't match it in catatonic, tomcat or certificate. Removing one of the boundaries, \bcat would match cat in catfish, and cat\b would match cat in tomcat, but not vice-versa. Both, of course, would match cat on its own.
Not-a-word-boundary: \B
\B matches all positions where \b doesn't match. Therefore, it matches:
? When neither side is a word character, for instance at any position in the string $=(@-%++) (including the beginning and end of the string)
? When both sides are a word character, for instance between the H and the i in Hi!
This may not seem very useful, but sometimes \B is just what you want. For instance,
? \Bcat\B will find cat fully surrounded by word characters, as in certificate, but neither on its own nor at the beginning or end of words.
? cat\B will find cat both in certificate and catfish, but neither in tomcat nor on its own.
? \Bcat will find cat both in certificate and tomcat, but neither in catfish nor on its own.
? \Bcat|cat\B will find cat in embedded situation, e.g. in certificate, catfish or tomcat, but not on its own.
From the man
page:
-d delim The first character of delim is used to terminate the input line, rather than newline.
You are using -d,
which will terminate the input line on the comma. It will not read the rest of the line. That's why $y is empty.
You'll be wanting to use glob()
Example:
$files = glob('/path/to/dir/*.xml');
The standard Pinterest button code (which you can generate here), is an <a>
tag wrapping an <img>
of the Pinterest button.
If you don't include the pinit.js
script on your page, this <a>
tag will work "as-is". You could improve the experience by registering your own click handler on these tags that opens a new window with appropriate dimensions, or at least adding target="_blank"
to the tag to make it open clicks in a new window.
The tag syntax would look like:
<a href="http://pinterest.com/pin/create/button/?url={URI-encoded URL of the page to pin}&media={URI-encoded URL of the image to pin}&description={optional URI-encoded description}" class="pin-it-button" count-layout="horizontal">
<img border="0" src="//assets.pinterest.com/images/PinExt.png" title="Pin It" />
</a>
If using the JavaScript versions of sharing buttons are ruining your page load times, you can improve your site by using asynchronous loading methods. For an example of doing this with the Pinterest button, check out my GitHub Pinterest button project with an improved HTML5 syntax.

The docker documentation (and self-explanation) makes a distinction between "virtual machines" vs. "containers". They have the tendency to interpret and use things in a little bit uncommon ways. They can do that because it is up to them, what do they write in their documentation, and because the terminology for virtualization is not yet really exact.
Fact is what the Docker documentation understands on "containers", is paravirtualization (sometimes "OS-Level virtualization") in the reality, contrarily the hardware virtualization, which is docker not.
Docker is a low quality paravirtualisation solution. The container vs. VM distinction is invented by the docker development, to explain the serious disadvantages of their product.
The reason, why it became so popular, is that they "gave the fire to the ordinary people", i.e. it made possible the simple usage of typically server ( = Linux) environments / software products on Win10 workstations. This is also a reason for us to tolerate their little "nuance". But it does not mean that we should also believe it.
The situation is made yet more cloudy by the fact that docker on Windows hosts used an embedded Linux in HyperV, and its containers have run in that. Thus, docker on Windows uses a combined hardware and paravirtualization solution.
In short, Docker containers are low-quality (para)virtual machines with a huge advantage and a lot of disadvantages.
Use dateutil.tz.tzlocal()
to get the timezone in your usage of datetime.datetime.now()
and datetime.datetime.astimezone()
:
from datetime import datetime
from dateutil import tz
unlocalisedDatetime = datetime.now()
localisedDatetime1 = datetime.now(tz = tz.tzlocal())
localisedDatetime2 = datetime(2017, 6, 24, 12, 24, 36, tz.tzlocal())
localisedDatetime3 = unlocalisedDatetime.astimezone(tz = tz.tzlocal())
localisedDatetime4 = unlocalisedDatetime.replace(tzinfo = tz.tzlocal())
Note that datetime.astimezone
will first convert your datetime
object to UTC then into the timezone, which is the same as calling datetime.replace
with the original timezone information being None
.

Since a ThreadLocal
is a reference to data within a given Thread
, you can end up with classloading leaks when using ThreadLocal
s in application servers using thread pools. You need to be very careful about cleaning up any ThreadLocal
s you get()
or set()
by using the ThreadLocal
's remove()
method.
If you do not clean up when you're done, any references it holds to classes loaded as part of a deployed webapp will remain in the permanent heap and will never get garbage collected. Redeploying/undeploying the webapp will not clean up each Thread
's reference to your webapp's class(es) since the Thread
is not something owned by your webapp. Each successive deployment will create a new instance of the class which will never be garbage collected.
You will end up with out of memory exceptions due to java.lang.OutOfMemoryError: PermGen space
and after some googling will probably just increase -XX:MaxPermSize
instead of fixing the bug.
If you do end up experiencing these problems, you can determine which thread and class is retaining these references by using Eclipse's Memory Analyzer and/or by following Frank Kieviet's guide and followup.
Update: Re-discovered Alex Vasseur's blog entry that helped me track down some ThreadLocal
issues I was having.

For Xcode users: If your rename your file in Xcode you see the badge icon change to append. If you do a commit using XCode you will actually create a new file and lose the history.
A workaround is easy but you have to do it before commiting using Xcode:
renamed: Project/OldName.h -> Project/NewName.h renamed: Project/OldName.m -> Project/NewName.m
Then go back to XCode and you will see the badge changed from A to M and it is save to commit furtur changes in using xcode now.

You could use LastIndexOf and Substring combined to get all characters to the left of the last index of the comma within the sting.
string var = var.Substring(0, var.LastIndexOf(','));
you can use decoration like this :
Container(
width: 60,
height: 60,
child: Icon(CustomIcons.option, size: 20,),
decoration: BoxDecoration(
shape: BoxShape.circle,
color: Color(0xFFe0f2f1)),
)
Now you have circle shape and Icon on it.
ZIP is a file format used for storing an arbitrary number of files and folders together with lossless compression. It makes no strict assumptions about the compression methods used, but is most frequently used with DEFLATE.
Gzip is both a compression algorithm based on DEFLATE but less encumbered with potential patents et al, and a file format for storing a single compressed file. It supports compressing an arbitrary number of files and folders when combined with tar. The resulting file has an extension of .tgz
or .tar.gz
and is commonly called a tarball.
zlib is a library of functions encapsulating DEFLATE in its most common LZ77 incarnation.
I would recommend taking advantage of the fact that nodeJS will always be ES5. Remember this isn't the browser folks you can depend on the language's implementation on being stable. That said I would recommend against ever using a for-in loop in nodeJS, unless you really want to do deep recursion up the prototype chain. For simple, traditional looping I would recommend making good use of Object.keys method, in ES5. If you view the following JSPerf test, especially if you use Chrome (since it has the same engine as nodeJS), you will get a rough idea of how much more performant using this method is than using a for-in loop (roughly 10 times faster). Here's a sample of the code:
var keys = Object.keys( obj );
for( var i = 0,length = keys.length; i < length; i++ ) {
obj[ keys[ i ] ];
}
It depends on how you want to use it. Using a Join is one way. Another way of doing it is let the thread notify the caller of the thread by using an event. For instance when you have your graphical user interface (GUI) thread that calls a process which runs for a while and needs to update the GUI when it finishes, you can use the event to do this. This website gives you an idea about how to work with events:
http://msdn.microsoft.com/en-us/library/aa645739%28VS.71%29.aspx
Remember that it will result in cross-threading operations and in case you want to update the GUI from another thread, you will have to use the Invoke
method of the control which you want to update.
axios.get
accepts a request config as the second parameter (not query string params).
You can use the params
config option to set query string params as follows:
axios.get('/api', {
params: {
foo: 'bar'
}
});
For others who land here in the future (including myself), add a -name option to find specific file types, for instance: find /var -name "*.php" -mtime -1 -ls
you can do it in two ways using
Serializable
Parcelable.
This examle will show you how to implement it with serializable
class Customer implements Serializable
{
// properties, getter setters & constructor
}
// This is your custom object
Customer customer = new Customer(name, address, zip);
Intent intent = new Intent();
intent.setClass(SourceActivity.this, TargetActivity.this);
intent.putExtra("customer", customer);
startActivity(intent);
// Now in your TargetActivity
Bundle extras = getIntent().getExtras();
if (extras != null)
{
Customer customer = (Customer)extras.getSerializable("customer");
// do something with the customer
}
Now have a look at this. This link will give you a brief overview of how to implement it with Parcelable.
Look at this.. This discussion will let you know which is much better way to implement it.
Thanks.
It has already been answered, the best way work-around is to convert the Stored Procedure into an SQL Function or a View.
The short answer, just as mentioned above, is that you cannot directly JOIN a Stored Procedure in SQL, not unless you create another stored procedure or function using the stored procedure's output into a temporary table and JOINing the temporary table, as explained above.
I will answer this by converting your Stored Procedure into an SQL function and show you how to use it inside a query of your choice.
CREATE FUNCTION fnMyFunc()
RETURNS TABLE AS
RETURN
(
SELECT tenant.ID AS TenantID,
SUM(ISNULL(trans.Amount,0)) AS TenantBalance
FROM tblTenant tenant
LEFT JOIN tblTransaction trans ON tenant.ID = trans.TenantID
GROUP BY tenant.ID
)
Now to use that function, in your SQL...
SELECT t.TenantName,
t.CarPlateNumber,
t.CarColor,
t.Sex,
t.SSNO,
t.Phone,
t.Memo,
u.UnitNumber,
p.PropertyName
FROM tblTenant t
LEFT JOIN tblRentalUnit u ON t.UnitID = u.ID
LEFT JOIN tblProperty p ON u.PropertyID = p.ID
LEFT JOIN dbo.fnMyFunc() AS a
ON a.TenantID = t.TenantID
ORDER BY p.PropertyName, t.CarPlateNumber
If you wish to pass parameters into your function from within the above SQL, then I recommend you use CROSS APPLY
or CROSS OUTER APPLY
.
Read up on that here.
Cheers
As it has been explained here, beside of multiple extensions that perform ad or script blocking you may aware that this may happen by file names as below:
Particularly in the AdBlock Plus the character string "-300x600" is causing the Failed to Load Resource ERR_BLOCKED_BY_CLIENT problem.
As shown in the picture, some of the images were blocked because of the '-300x600' pattern in their name, that particular text pattern matches an expression list pattern in the AdBlock Plus.
You're close. Just add the row to the tbody
instead of table
:
myTbody.insertRow();
Just get a reference to tBody
(myTbody
) before use. Notice that you don't need to pass the last position in a table; it's automatically positioned at the end when omitting argument.
[edit based on this now being possible in recent versions]
[Updated Answer] You can query the following way to get back the name of class and the student id only if they are already enrolled.
db.student.find({},
{_id:0, name:1, students:{$elemMatch:{$eq:ObjectId("51780f796ec4051a536015cf")}}})
and you will get back what you expected:
{ "name" : "CS 101", "students" : [ ObjectId("51780f796ec4051a536015cf") ] }
{ "name" : "Literature" }
{ "name" : "Physics", "students" : [ ObjectId("51780f796ec4051a536015cf") ] }
[Original Answer] It's not possible to do what you want to do currently. This is unfortunate because you would be able to do this if the student was stored in the array as an object. In fact, I'm a little surprised you are using just ObjectId() as that will always require you to look up the students if you want to display a list of students enrolled in a particular course (look up list of Id's first then look up names in the students collection - two queries instead of one!)
If you were storing (as an example) an Id and name in the course array like this:
{
"_id" : ObjectId("51780fb5c9c41825e3e21fc6"),
"name" : "Physics",
"students" : [
{id: ObjectId("51780f796ec4051a536015cf"), name: "John"},
{id: ObjectId("51780f796ec4051a536015d0"), name: "Sam"}
]
}
Your query then would simply be:
db.course.find( { },
{ students :
{ $elemMatch :
{ id : ObjectId("51780f796ec4051a536015d0"),
name : "Sam"
}
}
}
);
If that student was only enrolled in CS 101 you'd get back:
{ "name" : "Literature" }
{ "name" : "Physics" }
{
"name" : "CS 101",
"students" : [
{
"id" : ObjectId("51780f796ec4051a536015cf"),
"name" : "John"
}
]
}

It's important to make the difference between the App language and the device locale language (The code below is in Swift 3)
Will return the Device language:
let locale = NSLocale.current.languageCode
Will return the App language:
let pre = Locale.preferredLanguages[0]

Warnings are annoying. As mentioned in other answers, you can suppress them using:
import warnings
warnings.simplefilter(action='ignore', category=FutureWarning)
But if you want to handle them one by one and you are managing a bigger codebase, it will be difficult to find the line of code which is causing the warning. Since warnings unlike errors don't come with code traceback. In order to trace warnings like errors, you can write this at the top of the code:
import warnings
warnings.filterwarnings("error")
But if the codebase is bigger and it is importing bunch of other libraries/packages, then all sort of warnings will start to be raised as errors. In order to raise only certain type of warnings (in your case, its FutureWarning) as error, you can write:
import warnings
warnings.simplefilter(action='error', category=FutureWarning)
If the array contains both positive and negative data, I'd go with:
import numpy as np
a = np.random.rand(3,2)
# Normalised [0,1]
b = (a - np.min(a))/np.ptp(a)
# Normalised [0,255] as integer: don't forget the parenthesis before astype(int)
c = (255*(a - np.min(a))/np.ptp(a)).astype(int)
# Normalised [-1,1]
d = 2.*(a - np.min(a))/np.ptp(a)-1
If the array contains nan
, one solution could be to just remove them as:
def nan_ptp(a):
return np.ptp(a[np.isfinite(a)])
b = (a - np.nanmin(a))/nan_ptp(a)
However, depending on the context you might want to treat nan
differently. E.g. interpolate the value, replacing in with e.g. 0, or raise an error.
Finally, worth mentioning even if it's not OP's question, standardization:
e = (a - np.mean(a)) / np.std(a)
First of all, there's no such thing as a JSON object. What you've got in your question is a JavaScript object literal (see here for a great discussion on the difference). Here's how you would go about serializing what you've got to JSON though:
I would use an anonymous type filled with your results
type:
string json = JsonConvert.SerializeObject(new
{
results = new List<Result>()
{
new Result { id = 1, value = "ABC", info = "ABC" },
new Result { id = 2, value = "JKL", info = "JKL" }
}
});
Also, note that the generated JSON has result items with id
s of type Number
instead of strings. I doubt this will be a problem, but it would be easy enough to change the type of id
to string
in the C#.
I'd also tweak your results
type and get rid of the backing fields:
public class Result
{
public int id { get ;set; }
public string value { get; set; }
public string info { get; set; }
}
Furthermore, classes conventionally are PascalCased
and not camelCased
.
Here's the generated JSON from the code above:
{
"results": [
{
"id": 1,
"value": "ABC",
"info": "ABC"
},
{
"id": 2,
"value": "JKL",
"info": "JKL"
}
]
}
top level class: internal

A constexpr symbolic constant must be given a value that is known at compile time. For example:
?constexpr int max = 100;
void use(int n)
{
constexpr int c1 = max+7; // OK: c1 is 107
constexpr int c2 = n+7; // Error: we don’t know the value of c2
// ...
}
To handle cases where the value of a “variable” that is initialized with a value that is not known at compile time but never changes after initialization, C++ offers a second form of constant (a const). For Example:
?constexpr int max = 100;
void use(int n)
{
constexpr int c1 = max+7; // OK: c1 is 107
const int c2 = n+7; // OK, but don’t try to change the value of c2
// ...
c2 = 7; // error: c2 is a const
}
Such “const variables” are very common for two reasons:

ZonedDateTime.now( // Capture current moment as seen in the wall-clock time used by the people of a particular region (a time zone).
ZoneId.of( "America/Montreal" ) // Specify desired/expected time zone. Or pass `ZoneId.systemDefault` for the JVM’s current default time zone.
) // Returns a `ZonedDateTime` object.
.getMinute() // Extract the minute of the hour of the time-of-day from the `ZonedDateTime` object.
42
ZonedDateTime
To capture the current moment as seen in the wall-clock time used by the people of a particular region (a time zone), use ZonedDateTime
.
A time zone is crucial in determining a date. For any given moment, the date varies around the globe by zone. For example, a few minutes after midnight in Paris France is a new day while still “yesterday” in Montréal Québec.
If no time zone is specified, the JVM implicitly applies its current default time zone. That default may change at any moment during runtime(!), so your results may vary. Better to specify your desired/expected time zone explicitly as an argument.
Specify a proper time zone name in the format of continent/region
, such as America/Montreal
, Africa/Casablanca
, or Pacific/Auckland
. Never use the 3-4 letter abbreviation such as EST
or IST
as they are not true time zones, not standardized, and not even unique(!).
ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = ZonedDateTime.now( z ) ;
Call any of the many getters to pull out pieces of the date-time.
int year = zdt.getYear() ;
int monthNumber = zdt.getMonthValue() ;
String monthName = zdt.getMonth().getDisplayName( TextStyle.FULL , Locale.JAPAN ) ; // Locale determines human language and cultural norms used in localizing. Note that `Locale` has *nothing* to do with time zone.
int dayOfMonth = zdt.getDayOfMonth() ;
String dayOfWeek = zdt.getDayOfWeek().getDisplayName( TextStyle.FULL , Locale.CANADA_FRENCH ) ;
int hour = zdt.getHour() ; // Extract the hour from the time-of-day.
int minute = zdt.getMinute() ;
int second = zdt.getSecond() ;
int nano = zdt.getNano() ;
The java.time classes resolve to nanoseconds. Your Question asked for the fraction of a second in milliseconds. Obviously, you can divide by a million to truncate nanoseconds to milliseconds, at the cost of possible data loss. Or use the TimeUnit
enum for such conversion.
long millis = TimeUnit.NANOSECONDS.toMillis( zdt.getNano() ) ;
DateTimeFormatter
To produce a String
to combine pieces of text, use DateTimeFormatter
class. Search Stack Overflow for more info on this.
Instant
Usually best to track moments in UTC. To adjust from a zoned date-time to UTC, extract a Instant
.
Instant instant = zdt.toInstant() ;
And go back again.
ZonedDateTime zdt = instant.atZone( ZoneId.of( "Africa/Tunis" ) ) ;
LocalDateTime
A couple of other Answers use the LocalDateTime
class. That class in not appropriate to the purpose of tracking actual moments, specific moments on the timeline, as it intentionally lacks any concept of time zone or offset-from-UTC.
So what is LocalDateTime
good for? Use LocalDateTime
when you intend to apply a date & time to any locality or all localities, rather than one specific locality.
For example, Christmas this year starts at the LocalDateTime.parse( "2018-12-25T00:00:00" )
. That value has no meaning until you apply a time zone (a ZoneId
) to get a ZonedDateTime
. Christmas happens first in Kiribati, then later in New Zealand and far east Asia. Hours later Christmas starts in India. More hour later in Africa & Europe. And still not Xmas in the Americas until several hours later. Christmas starting in any one place should be represented with ZonedDateTime
. Christmas everywhere is represented with a LocalDateTime
.
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes.
Where to obtain the java.time classes?
sed -i '/pattern/d' file
Use 'd' to delete a line. This works at least with GNU-Sed.
If your Sed doesn't have the option, to change a file in place, maybe you can use an intermediate file, to store the modification:
sed '/pattern/d' file > tmpfile && mv tmpfile file
Writing directly to the source usually doesn't work: sed '/pattern/d' file > file
so make a copy before trying out, if you doubt it.
There is a library called PhoneNumberUtils that can help you to cope with phone number conversions and comparisons. For instance, use ...
EditText text = (EditText) findViewById(R.id.editTextId);
PhoneNumberUtils.formatNumber(text.getText().toString())
... to format your number in a standard format.
PhoneNumberUtils.compare(String a, String b);
... helps with fuzzy comparisons. There are lots more. Check out http://developer.android.com/reference/android/telephony/PhoneNumberUtils.html for more.
p.s. setting the the EditText to phone
is already a good choice; eventually it might be helpful to add digits
e.g. in your layout it looks as ...
<EditText
android:id="@+id/editTextId"
android:inputType="phone"
android:digits="0123456789+"
/>
Asterisk symbol (*) is used to check values in the array, not the array itself.
$validator = Validator::make($request->all(), [
"names" => "required|array|min:3",
"names.*" => "required|string|distinct|min:3",
]);
In the example above:
EDIT: Since Laravel 5.5 you can call validate() method directly on Request object like so:
$data = $request->validate([
"name" => "required|array|min:3",
"name.*" => "required|string|distinct|min:3",
]);
Google only allows images which are coming from trusted source .

Just json.dumps will fix the problem
json.dumps function actually converts all the unicode literals to string literals and it will be easy for us to load the data either in json file or csv file.
sample code:
import json
EmployeeList = [u'1001', u'Karick', u'14-12-2020', u'1$']
result_list = json.dumps(EmployeeList)
print result_list
output: ["1001", "Karick", "14-12-2020", "1$"]
Use std::cout
, since cout
is defined within the std
namespace. Alternatively, add a using std::cout;
directive.
Would something like this do what you need?
class Test(object):
def _decorator(foo):
def magic( self ) :
print "start magic"
foo( self )
print "end magic"
return magic
@_decorator
def bar( self ) :

test = Test()
test.bar()
This avoids the call to self to access the decorator and leaves it hidden in the class namespace as a regular method.
>>> import stackoverflow
>>> test = stackoverflow.Test()
>>> test.bar()
start magic
normal call
end magic

try/catch is scripted syntax. So any time you are using declarative syntax to use something from scripted in general you can do so by enclosing the scripted syntax in the scripts block in a declarative pipeline. So your try/catch should go inside stage >steps >script.
This holds true for any other scripted pipeline syntax you would like to use in a declarative pipeline as well.
I like to iterate backward using a for
loop, but this can get tedious compared to foreach
. One solution I like is to create an enumerator that traverses the list backward. You can implement this as an extension method on ArrayList
or List<T>
. The implementation for ArrayList
is below.
public static IEnumerable GetRemoveSafeEnumerator(this ArrayList list)
{
for (int i = list.Count - 1; i >= 0; i--)
{
// Reset the value of i if it is invalid.
// This occurs when more than one item
// is removed from the list during the enumeration.
if (i >= list.Count)
{
if (list.Count == 0)
yield break;
i = list.Count - 1;
}
yield return list[i];
}
}
The implementation for List<T>
is similar.
public static IEnumerable<T> GetRemoveSafeEnumerator<T>(this List<T> list)
{
for (int i = list.Count - 1; i >= 0; i--)
{
// Reset the value of i if it is invalid.
// This occurs when more than one item
// is removed from the list during the enumeration.
if (i >= list.Count)
{
if (list.Count == 0)
yield break;
i = list.Count - 1;
}
yield return list[i];
}
}
The example below uses the enumerator to remove all even integers from an ArrayList
.
ArrayList list = new ArrayList() {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
foreach (int item in list.GetRemoveSafeEnumerator())
{
if (item % 2 == 0)
list.Remove(item);
}
If you give a Scanner object a String, it will read it in as data. That is, "a.txt" does not open up a file called "a.txt". It literally reads in the characters 'a', '.', 't' and so forth.
This is according to Core Java Volume I, section 3.7.3.
If I find a solution to reading the actual paths, I will return and update this answer. The solution this text offers is to use
Scanner in = new Scanner(Paths.get("myfile.txt"));
But I can't get this to work because Path isn't recognized as a variable by the compiler. Perhaps I'm missing an import statement.

In your link function, do this:
// link function
function (scope, element, attrs) {
var myEl = angular.element(element[0].querySelector('.list-scrollable'));
}
Also, in your link function, don't name your scope
variable using a $
. That is an angular convention that is specific to built in angular services, and is not something that you want to use for your own variables.
The Bootstrap3 .form-control
is cool but for those who love or need the drop-down with button and ul option, here is the updated code. I have edited the code by Steve to fix jumping to the hash link and closing the drop-down after selection.
Thanks to Steve, Ben and Skelly!
$(".dropdown-menu li a").click(function () {
var selText = $(this).text();
$(this).closest('div').find('button[data-toggle="dropdown"]').html(selText + ' <span class="caret"></span>');
$(this).closest('.dropdown').removeClass("open");
return false;
});
