Use %systemdrive%%homepath%
. %systemdrive%
gives drive character ( Mostly C:
) and %homepath%
gives user home directory ( \Users\<USERNAME>
).
os.homedir()
was added by this PR and is part of the public 4.0.0 release of nodejs.
Example usage:
const os = require('os');
console.log(os.homedir());
Are they the home directories of users in /etc/passwd
? Services like postgres, sendmail, apache, etc., create system users that have home directories just like normal users.
Of course, never fails. Found the solution about a minute after posting the above question... solution for those that may have had the same issue:
ContextWrapper.getFilesDir()
Found here.
I know this is an old thread, but I recently needed this for a large scale project (Python 3.8). It had to work on any mainstream OS, so therefore I went with the solution @Max wrote in the comments.
Code:
import os
print(os.path.expanduser("~"))
Output Windows:
PS C:\Python> & C:/Python38/python.exe c:/Python/test.py
C:\Users\mXXXXX
Output Linux (Ubuntu):
rxxx@xx:/mnt/c/Python$ python3 test.py
/home/rxxx
I also tested it on Python 2.7.17 and that works too.
System.getProperty("user.home");
See the JavaDoc.
Is there something special with that directory or are you really just asking how to copy directories?
Copy recursively via CLI:
cp -R <sourcedir> <destdir>
If you're only seeing the files under the sourcedir
being copied (instead of sourcedir
as well), that's happening because you kept the trailing slash for sourcedir
:
cp -R <sourcedir>/ <destdir>
The above only copies the files and their directories inside of sourcedir
. Typically, you want to include the directory you're copying, so drop the trailing slash:
cp -R <sourcedir> <destdir>
0 in the start here specifies that the base is 8 (not 10), which is pretty easy to see:
>>> int('010101', 0)
4161
If you don't start with a 0, then python assumes the number is base 10.
>>> int('10101', 0)
10101

We had an issue relating to duplicated data in our database, with a date field having multiple values where we were meant to have 1. I thought I'd add the way we resolved the issue for reference.
We have a collection called "data" with a numeric "value" field and a date "date" field. We had a process which we thought was idempotent, but ended up adding 2 x values per day on second run:
{ "_id" : "1", "type":"x", "value":1.23, date : ISODate("2013-05-21T08:00:00Z")}
{ "_id" : "2", "type":"x", "value":1.23, date : ISODate("2013-05-21T17:00:00Z")}
We only need 1 of the 2 records, so had to resort the javascript to clean up the db. Our initial approach was going to be to iterate through the results and remove any field with a time of between 6am and 11am (all duplicates were in the morning), but during implementation, made a change. Here's the script used to fix it:
var data = db.data.find({"type" : "x"})
var found = [];
while (data.hasNext()){
var datum = data.next();
var rdate = datum.date;
// instead of the next set of conditions, we could have just used rdate.getHour() and checked if it was in the morning, but this approach was slightly better...
if (typeof found[rdate.getDate()+"-"+rdate.getMonth() + "-" + rdate.getFullYear()] !== "undefined") {
if (datum.value != found[rdate.getDate()+"-"+rdate.getMonth() + "-" + rdate.getFullYear()]) {
print("DISCREPENCY!!!: " + datum._id + " for date " + datum.date);
}
else {
print("Removing " + datum._id);
db.data.remove({ "_id": datum._id});
}
}
else {
found[rdate.getDate()+"-"+rdate.getMonth() + "-" + rdate.getFullYear()] = datum.value;
}
}
and then ran it with mongo thedatabase fixer_script.js
A lot of answers have been given, based on technical considerations, especially around performance.
According to me, choice between TreeSet
and HashSet
matters.
But I would rather say the choice should be driven by conceptual considerations first.
If, for the objects your need to manipulate, a natural ordering does not make sense, then do not use TreeSet
.
It is a sorted set, since it implements SortedSet
. So it means you need to override function compareTo
, which should be consistent with what returns function equals
. For example if you have a set of objects of a class called Student, then I do not think a TreeSet
would make sense, since there is no natural ordering between students. You can order them by their average grade, okay, but this is not a "natural ordering". Function compareTo
would return 0 not only when two objects represent the same student, but also when two different students have the same grade. For the second case, equals
would return false (unless you decide to make the latter return true when two different students have the same grade, which would make equals
function have a misleading meaning, not to say a wrong meaning.)
Please note this consistency between equals
and compareTo
is optional, but strongly recommended. Otherwise the contract of interface Set
is broken, making your code misleading to other people, thus also possibly leading to unexpected behavior.
This link might be a good source of information regarding this question.
Although this question is 5 years old I have come across a nice solution.
Use the 'DictionaryEntry' object to pair keys and values.
Set the 'DisplayMember' and 'ValueMember' properties to:
Me.myComboBox.DisplayMember = "Key"
Me.myComboBox.ValueMember = "Value"
To add items to the ComboBox:
Me.myComboBox.Items.Add(New DictionaryEntry("Text to be displayed", 1))
To retreive items like this:
MsgBox(Me.myComboBox.SelectedItem.Key & " " & Me.myComboBox.SelectedItem.Value)
Not sure of the exact question but is this what you are looking for?

I have tested a full layout using flexbox it contains header, footer, main body with left, center and right panels and the panels can contain menu items or footer and headers that should scroll. Pretty complex
IE11 and even IE EDGE have some problems displaying the flex content but it can be overcome. I have tested it in most browsers and it seems to work.
Some fixed i have applies are IE11 height bug, Adding height:100vh and min-height:100% to the html/body. this also helps to not have to set height on container in the dom. Also make the body/html a flex container. Otherwise IE11 will compress the view.
html,body {
display: flex;
flex-flow:column nowrap;
height:100vh; /* fix IE11 */
min-height:100%; /* fix IE11 */
}
A fix for IE EDGE that overflows the flex container: overflow:hidden on main flex container. if you remove the overflow, IE EDGE wil push the content out of the viewport instead of containing it inside the flex main container.
main{
flex:1 1 auto;
overflow:hidden; /* IE EDGE overflow fix */
}
You can see my testing and example on my codepen page. I remarked the important css parts with the fixes i have applied and hope someone finds it useful.

This part of the code will take the latex file format of the jupyter notebook and converts it to a html
--no-input
This is like a parameter we are saying during conversion that dont add any inputs : here the input to a cell is the code.. so we hide it
--no-prompt
Here also we are saying, During conversion dont show any prompts form the code like errors or warnings in the final HTML file ) so that that html will have only the Text and the code output in the form of a report !!..
Hope it helps :)
PHP manual has a good read on the question here.
The visibility of a property or method can be defined by prefixing the declaration with the keywords public, protected or private. Class members declared public can be accessed everywhere. Members declared protected can be accessed only within the class itself and by inherited and parent classes. Members declared as private may only be accessed by the class that defines the member.
Assign after the EXEC
token:
DECLARE @returnValue INT
EXEC @returnValue = SP_One
You need to put your main code on the OnStart
method.
This other SO answer of mine might help.
You will need to put some code to enable debugging within visual-studio while maintaining your application valid as a windows-service. This other SO thread cover the issue of debugging a windows-service.
EDIT:
Please see also the documentation available here for the OnStart
method at the MSDN where one can read this:
Do not use the constructor to perform processing that should be in OnStart. Use OnStart to handle all initialization of your service. The constructor is called when the application's executable runs, not when the service runs. The executable runs before OnStart. When you continue, for example, the constructor is not called again because the SCM already holds the object in memory. If OnStop releases resources allocated in the constructor rather than in OnStart, the needed resources would not be created again the second time the service is called.
The latter alternative is used for methods on mocks that return void
.
Please have a look, for example, here: How to make mock to void methods with mockito
ipdb adds IPython functionality to pdb, offering the following HUGE improvements:
Much like pdg, ipdb is still far from perfect and completely rudimentary if compared to GDB, but it is already a huge improvement over pdb.
Usage is analogous to pdb
, just install it with:
python3 -m pip install --user ipdb
and then add to the line you want to step debug from:
__import__('ipdb').set_trace(context=21)
You likely want to add a shortcut for that from your editor, e.g. for Vim snipmate I have:
snippet ipd
__import__('ipdb').set_trace(context=21)
so I can type just ipd<tab>
and it expands to the breakpoint. Then removing it is easy with dd
since everything is contained in a single line.
context=21
increases the number of context lines as explained at: How can I make ipdb show more lines of context while debugging?
Alternatively, you can also debug programs from the start with:
ipdb3 main.py
but you generally don't want to do that because:
Or alternatively, as in raw pdb 3.2+ you can set some breakpoints from the command line:
ipdb3 -c 'b 12' -c 'b myfunc' ~/test/a.py
although -c c
is broken for some reason: https://github.com/gotcha/ipdb/issues/156
python -m module
debugging has been asked at: How to debug a Python module run with python -m from the command line? and since Python 3.7 can be done with:
python -m pdb -m my_module
Serious missing features of both pdb and ipdb compared to GDB:
ipdb specific annoyances:
Tested in Ubuntu 16.04, ipdb==0.11, Python 3.5.2.

Ajax is a way of using Javascript for communicating with serverside without loading the page over again. jQuery uses ajax for many of its functions, but it nothing else than a library that provides easier functionality.
With jQuery you dont have to think about creating xml objects ect ect, everything is done for you, but with straight up javascript ajax you need to program every single step of the ajax call.
Use CSS styles with CSS Classes instead
CSS
.error {
border:2px solid red;
}
Now in Javascript
document.getElementById("fName").className = document.getElementById("fName").className + " error"; // this adds the error class
document.getElementById("fName").className = document.getElementById("fName").className.replace(" error", ""); // this removes the error class
The main reason I mention this is suppose you want to change the color of the errored element's border. If you choose your way you will may need to modify many places in code. If you choose my way you can simply edit the style sheet.
Or for custom options
<%= f.select :desired_attribute, ['option1', 'option2']%>
@Paul Cavacas, I had the same issue and I solved by setting the Input()
decorator above the getter.
@Input('allowDays')
get in(): any {
return this._allowDays;
}
//@Input('allowDays')
// not working
set in(val) {
console.log('allowDays = '+val);
this._allowDays = val;
}

Here's a list of all the ways I could think of to counting unique elements:
M = randi([1 7], [1500 1]);
t = tabulate(M);
counts1 = t(t(:,2)~=0, 2);
counts2_1 = hist( M, numel(unique(M)) );
counts2_2 = histc( M, unique(M) );
counts3 = accumarray(M, ones(size(M)), [], @sum);
%# or simply: accumarray(M, 1);
[MM idx] = unique( sort(M) );
counts4 = diff([0;idx]);
counts5 = arrayfun( @(x)sum(M==x), unique(M) );
counts6 = sum( bsxfun(@eq, M, unique(M)') )';
counts7 = full(sparse(M,1,1));
<?php if ($foo) { ?>
<div class="mydiv">Condition is true</div>
<?php } else { ?>
<div class="myotherdiv">Condition is false</div>
<?php } ?>
In java there is no explicit way doing garbage collection. The JVM itself runs some threads in the background checking for the objects that are not having any references which means all the ways through which we access the object are lost. On the other hand an object is also eligible for garbage collection if it runs out of scope that is the program in which we created the object is terminated or ended. Coming to your question the method finalize is same as the destructor in C++. The finalize method is actually called just before the moment of clearing the object memory by the JVM. It is up to you to define the finalize method or not in your program. However if the garbage collection of the object is done after the program is terminated then the JVM will not invoke the finalize method which you defined in your program. You might ask what is the use of finalize method? For instance let us consider that you created an object which requires some stream to external file and you explicitly defined a finalize method to this object which checks wether the stream opened to the file or not and if not it closes the stream. Suppose, after writing several lines of code you lost the reference to the object. Then it is eligible for garbage collection. When the JVM is about to free the space of your object the JVM just checks have you defined the finalize method or not and invokes the method so there is no risk of the opened stream. finalize method make the program risk free and more robust.
Add nth Days, months and years
$n = 2;
for ($i = 0; $i <= $n; $i++){
$d = strtotime("$i days");
$x = strtotime("$i month");
$y = strtotime("$i year");
echo "Dates : ".$dates = date('d M Y', "+$d days");
echo "<br>";
echo "Months : ".$months = date('M Y', "+$x months");
echo '<br>';
echo "Years : ".$years = date('Y', "+$y years");
echo '<br>';
}
In LINQ you could do something like:
foreach (var data in from DataRow row in dataTable.Rows
from DataColumn col in dataTable.Columns
where
row[col] != null
select row[col])
{
// do something with data
}
spans not have the value in html
one is the id
for span
tag
in javascript use
document.getElementById('one').innerText;
in jQuery use
$('#one').text()
function check() {
var content = document.getElementById("one").innerText;
alert(content);
}
or
function check() {
var content = $('#one').text();
alert(content);
}
break
will exit the loop completely, continue
will just skip the current iteration.
For example:
for (int i = 0; i < 10; i++) {
if (i == 0) {
break;
}
DoSomeThingWith(i);
}
The break will cause the loop to exit on the first iteration - DoSomeThingWith
will never be executed. This here:
for (int i = 0; i < 10; i++) {
if(i == 0) {
continue;
}
DoSomeThingWith(i);
}
Will not execute DoSomeThingWith
for i = 0
, but the loop will continue and DoSomeThingWith
will be executed for i = 1
to i = 9
.
If you use the overflow:hidden
hack on the <body>
element, to get back normal scrolling behavior, you can position a <div>
absolutely inside of the element to get scrolling back with overflow:auto
. I think this is the best option, and it's quite easy to implement using only css!
Or, you can try with jQuery:
$(document).bind(
'touchmove',
function(e) {
e.preventDefault();
}
);
Same in javasrcipt:
document.addEventListener(
'touchmove',
function(e) {
e.preventDefault();
},
false
);
Last option, check ipad safari: disable scrolling, and bounce effect?
GCD
is a low-level C-based API that enables very simple use of a task-based concurrency model. NSOperation
and NSOperationQueue
are Objective-C classes that do a similar thing. NSOperation
was introduced first, but as of 10.5 and iOS 2, NSOperationQueue
and friends are internally implemented using GCD
.
In general, you should use the highest level of abstraction that suits your needs. This means that you should usually use NSOperationQueue
instead of GCD
, unless you need to do something that NSOperationQueue
doesn't support.
Note that NSOperationQueue
isn't a "dumbed-down" version of GCD; in fact, there are many things that you can do very simply with NSOperationQueue
that take a lot of work with pure GCD
. (Examples: bandwidth-constrained queues that only run N operations at a time; establishing dependencies between operations. Both very simple with NSOperation
, very difficult with GCD
.) Apple's done the hard work of leveraging GCD to create a very nice object-friendly API with NSOperation
. Take advantage of their work unless you have a reason not to.
Caveat:
On the other hand, if you really just need to send off a block, and don't need any of the additional functionality that NSOperationQueue
provides, there's nothing wrong with using GCD. Just be sure it's the right tool for the job.
Adding to the first answer, I think .service() is for people who have written their code in more object oriented style(C#/Java) (using this keyword and instantiating object via prototype/Constructor function).
Factory is for developers who write code which is more natural to javascript/functional style of coding.
Take a look at the source code of .service and .factory method inside angular.js - internally they all call provider method:
function provider(name, provider_) {
if (isFunction(provider_)) {
provider_ = providerInjector.instantiate(provider_);
}
if (!provider_.$get) {
throw Error('Provider ' + name + ' must define $get factory method.');
}
return providerCache[name + providerSuffix] = provider_;
}
function factory(name, factoryFn) { \
return provider(name, { $get: factoryFn });
}
function service(name, constructor) {
return factory(name, ['$injector', function($injector) {
return $injector.instantiate(constructor);
}]);
}
I used this method:
$(document).mousemove(function(e) {
window.x = e.pageX;
window.y = e.pageY;
});
function show_popup(str) {
$("#popup_content").html(str);
$("#popup").fadeIn("fast");
$("#popup").css("top", y);
$("#popup").css("left", x);
}
In this way I'll always have the distance from the top saved in y and the distance from the left saved in x.
DateTimeOffset
is a representation of instantaneous time (also known as absolute time). By that, I mean a moment in time that is universal for everyone (not accounting for leap seconds, or the relativistic effects of time dilation). Another way to represent instantaneous time is with a DateTime
where .Kind
is DateTimeKind.Utc
.
This is distinct from calendar time (also known as civil time), which is a position on someone's calendar, and there are many different calendars all over the globe. We call these calendars time zones. Calendar time is represented by a DateTime
where .Kind
is DateTimeKind.Unspecified
, or DateTimeKind.Local
. And .Local
is only meaningful in scenarios where you have an implied understanding of where the computer that is using the result is positioned. (For example, a user's workstation)
So then, why DateTimeOffset
instead of a UTC DateTime
? It's all about perspective. Let's use an analogy - we'll pretend to be photographers.
Imagine you are standing on a calendar timeline, pointing a camera at a person on the instantaneous timeline laid out in front of you. You line up your camera according to the rules of your timezone - which change periodically due to daylight saving time, or due to other changes to the legal definition of your time zone. (You don't have a steady hand, so your camera is shaky.)
The person standing in the photo would see the angle at which your camera came from. If others were taking pictures, they could be from different angles. This is what the Offset
part of the DateTimeOffset
represents.
So if you label your camera "Eastern Time", sometimes you are pointing from -5, and sometimes you are pointing from -4. There are cameras all over the world, all labeled different things, and all pointing at the same instantaneous timeline from different angles. Some of them are right next to (or on top of) each other, so just knowing the offset isn't enough to determine which timezone the time is related to.
And what about UTC? Well, it's the one camera out there that is guaranteed to have a steady hand. It's on a tripod, firmly anchored into the ground. It's not going anywhere. We call its angle of perspective the zero offset.
So - what does this analogy tell us? It provides some intuitive guidelines-
If you are representing time relative to some place in particular, represent it in calendar time with a DateTime
. Just be sure you don't ever confuse one calendar with another. Unspecified
should be your assumption. Local
is only useful coming from DateTime.Now
. For example, I might get DateTime.Now
and save it in a database - but when I retrieve it, I have to assume that it is Unspecified
. I can't rely that my local calendar is the same calendar that it was originally taken from.
If you must always be certain of the moment, make sure you are representing instantaneous time. Use DateTimeOffset
to enforce it, or use UTC DateTime
by convention.
If you need to track a moment of instantaneous time, but you want to also know "What time did the user think it was on their local calendar?" - then you must use a DateTimeOffset
. This is very important for timekeeping systems, for example - both for technical and legal concerns.
If you ever need to modify a previously recorded DateTimeOffset
- you don't have enough information in the offset alone to ensure that the new offset is still relevant for the user. You must also store a timezone identifier (think - I need the name of that camera so I can take a new picture even if the position has changed).
It should also be pointed out that Noda Time has a representation called ZonedDateTime
for this, while the .Net base class library does not have anything similar. You would need to store both a DateTimeOffset
and a TimeZoneInfo.Id
value.
Occasionally, you will want to represent a calendar time that is local to "whomever is looking at it". For example, when defining what today means. Today is always midnight to midnight, but these represent a near-infinite number of overlapping ranges on the instantaneous timeline. (In practice we have a finite number of timezones, but you can express offsets down to the tick) So in these situations, make sure you understand how to either limit the "who's asking?" question down to a single time zone, or deal with translating them back to instantaneous time as appropriate.
Here are a few other little bits about DateTimeOffset
that back up this analogy, and some tips for keeping it straight:
If you compare two DateTimeOffset
values, they are first normalized to zero offset before comparing. In other words, 2012-01-01T00:00:00+00:00
and 2012-01-01T02:00:00+02:00
refer to the same instantaneous moment, and are therefore equivalent.
If you are doing any unit testing and need to be certain of the offset, test both the DateTimeOffset
value, and the .Offset
property separately.
There is a one-way implicit conversion built in to the .Net framework that lets you pass a DateTime
into any DateTimeOffset
parameter or variable. When doing so, the .Kind
matters. If you pass a UTC kind, it will carry in with a zero offset, but if you pass either .Local
or .Unspecified
, it will assume to be local. The framework is basically saying, "Well, you asked me to convert calendar time to instantaneous time, but I have no idea where this came from, so I'm just going to use the local calendar." This is a huge gotcha if you load up an unspecified DateTime
on a computer with a different timezone. (IMHO - that should throw an exception - but it doesn't.)
Shameless Plug:
Many people have shared with me that they find this analogy extremely valuable, so I included it in my Pluralsight course, Date and Time Fundamentals. You'll find a step-by-step walkthrough of the camera analogy in the second module, "Context Matters", in the clip titled "Calendar Time vs. Instantaneous Time".

In order to hide the default radio button, I'd suggest to remove the button instead of making it transparent as all visual feedback is handled by the drawable background :
android:button="@null"
Also it would be better to use styles as there are several radio buttons :
<RadioButton style="@style/RadioButtonStyle" ... />
<style name="RadioButtonStyle" parent="@android:style/Widget.CompoundButton">
<item name="android:background">@drawable/customButtonBackground</item>
<item name="android:button">@null</item>
</style>
You'll need the Seslyn customButtonBackground drawable too.

You can do that with this the following classes. This class is a generic class is the client endpoint. It enables IOC of various encryption algorithms using Ninject.
public class StringEncryptor
{
private static IKernel _kernel;
static StringEncryptor()
{
_kernel = new StandardKernel(new EncryptionModule());
}
public static string EncryptString(string plainText)
{
return _kernel.Get<IStringEncryptor>().EncryptString(plainText);
}
public static string DecryptString(string encryptedText)
{
return _kernel.Get<IStringEncryptor>().DecryptString(encryptedText);
}
}
This next class is the ninject class that allows you to inject the various algorithms:
public class EncryptionModule : StandardModule
{
public override void Load()
{
Bind<IStringEncryptor>().To<TripleDESStringEncryptor>();
}
}
This is the interface that any algorithm needs to implement to encrypt/decrypt strings:
public interface IStringEncryptor
{
string EncryptString(string plainText);
string DecryptString(string encryptedText);
}
This is a implementation using the TripleDES algorithm:
public class TripleDESStringEncryptor : IStringEncryptor
{
private byte[] _key;
private byte[] _iv;
private TripleDESCryptoServiceProvider _provider;
public TripleDESStringEncryptor()
{
_key = System.Text.ASCIIEncoding.ASCII.GetBytes("GSYAHAGCBDUUADIADKOPAAAW");
_iv = System.Text.ASCIIEncoding.ASCII.GetBytes("USAZBGAW");
_provider = new TripleDESCryptoServiceProvider();
}
#region IStringEncryptor Members
public string EncryptString(string plainText)
{
return Transform(plainText, _provider.CreateEncryptor(_key, _iv));
}
public string DecryptString(string encryptedText)
{
return Transform(encryptedText, _provider.CreateDecryptor(_key, _iv));
}
#endregion
private string Transform(string text, ICryptoTransform transform)
{
if (text == null)
{
return null;
}
using (MemoryStream stream = new MemoryStream())
{
using (CryptoStream cryptoStream = new CryptoStream(stream, transform, CryptoStreamMode.Write))
{
byte[] input = Encoding.Default.GetBytes(text);
cryptoStream.Write(input, 0, input.Length);
cryptoStream.FlushFinalBlock();
return Encoding.Default.GetString(stream.ToArray());
}
}
}
}

The apostrophe character can be inserted by calling the CHAR function with the apostrophe's ASCII table lookup value, 39. The string values can then be concatenated together with a concatenate operator.
Insert into Person

'Joe',
concat('O',char(39),'Brien')
Inspired by TheIT, I just got this to work by manipulating the manifest file but in a slightly different fashion. Set the icon in the application setting so that the majority of the activities get the icon. On the activity where you want to show the logo, add the android:logo attribute to the activity declaration. In the following example, only LogoActivity should have the logo, while the others will default to icon.
<application
android:name="com.your.app"
android:icon="@drawable/your_icon"
android:label="@string/app_name">
<activity
android:name="com.your.app.LogoActivity"
android:logo="@drawable/your_logo"
android:label="Logo Activity" >
<activity
android:name="com.your.app.IconActivity1"
android:label="Icon Activity 1" >
<activity
android:name="com.your.app.IconActivity2"
android:label="Icon Activity 2" >
</application>
Hope this helps someone else out!
I was missing several DLLs. Even if I manually copied them to the directory the next time I published they would disappear. Each one was already set to Copy Locally in VS. The fix for me was to set each one to Copy Locally false, save, build then set each one to copy locally true. This time when I published all of the DLLs published correctly. Strange
Quote:
These two properties allow a website or user to require an element’s font size to be clamped within the range supplied with these two properties. If the computed value font-size is outside the bounds created by font-min-size and font-max-size, the use value of font-size is clamped to the values specified in these two properties.
This would actually work as following:
.element {
font-min-size: 10px;
font-max-size: 18px;
font-size: 5vw; // viewport-relative units are responsive.
}
This would literally mean, the font size will be 5% of the viewport's width, but never smaller than 10 pixels, and never larger than 18 pixels.
Unfortunately, this feature isn't implemented anywhere yet, (not even on caniuse.com).
You can also use string.match().
var string1 = "aBc";
var match = string1.match(/AbC/i);
if(match) {
}
This all depends on what sort of access you have to your SAP system. An ABAP program that exports the data and/or an RFC that your macro can call to directly get the data or have SAP create the file is probably best.
However as a general rule people looking for this sort of answer are looking for an immediate solution that does not require their IT department to spend months customizing their SAP system.
In that case you probably want to use SAP GUI Scripting. SAP GUI scripting allows you to automate the Windows SAP GUI in much the same way as you automate Excel. In fact you can call the SAP GUI directly from an Excel macro. Read up more on it here. The SAP GUI has a macro recording tool much like Excel does. It records macros in VBScript which is nearly identical to Excel VBA and can usually be copied and pasted into an Excel macro directly.
Here is a simple example based on a SAP system I have access to.
Public Sub SimpleSAPExport()
Set SapGuiAuto = GetObject("SAPGUI") 'Get the SAP GUI Scripting object
Set SAPApp = SapGuiAuto.GetScriptingEngine 'Get the currently running SAP GUI
Set SAPCon = SAPApp.Children(0) 'Get the first system that is currently connected
Set session = SAPCon.Children(0) 'Get the first session (window) on that connection
'Start the transaction to view a table
session.StartTransaction "SE16"
'Select table T001
session.findById("wnd[0]/usr/ctxtDATABROWSE-TABLENAME").Text = "T001"
session.findById("wnd[0]/tbar[1]/btn[7]").Press
'Set our selection criteria
session.findById("wnd[0]/usr/txtMAX_SEL").text = "2"
session.findById("wnd[0]/tbar[1]/btn[8]").press
'Click the export to file button
session.findById("wnd[0]/tbar[1]/btn[45]").press
'Choose the export format
session.findById("wnd[1]/usr/subSUBSCREEN_STEPLOOP:SAPLSPO5:0150/sub:SAPLSPO5:0150/radSPOPLI-SELFLAG[1,0]").select
session.findById("wnd[1]/tbar[0]/btn[0]").press
'Choose the export filename
session.findById("wnd[1]/usr/ctxtDY_FILENAME").text = "test.txt"
session.findById("wnd[1]/usr/ctxtDY_PATH").text = "C:\Temp\"
'Export the file
session.findById("wnd[1]/tbar[0]/btn[0]").press
End Sub
To help find the names of elements such aswnd[1]/tbar[0]/btn[0]
you can use script recording.
Click the customize local layout button, it probably looks a bit like this:
Then find the Script Recording and Playback menu item.
Within that the More
button allows you to see/change the file that the VB Script is recorded to. The output format is a bit messy, it records things like selecting text, clicking inside a text field, etc.
The provided script should work if copied directly into a VBA macro. It uses late binding, the line Set SapGuiAuto = GetObject("SAPGUI")
defines the SapGuiAuto object.
If however you want to use early binding so that your VBA editor might show the properties and methods of the objects you are using, you need to add a reference to sapfewse.ocx
in the SAP GUI installation folder.
You can do it very easily with a Cloud Management software -like enStratus, RightScale or Scalr (disclaimer: I work there). With the cloned farm you can:
Because most of solutions is bit outdated I could also suggest asciitable which already available in maven (de.vandermeer:asciitable:0.3.2
) and may produce very complicated configurations.
And usage still looks easy:
AsciiTable at = new AsciiTable();
at.addRule();
at.addRow("row 1 col 1", "row 1 col 2");
at.addRule();
at.addRow("row 2 col 1", "row 2 col 2");
at.addRule();
System.out.println(at.render()); // Finally, print the table to standard out.
From looking at man mailx
, the mailx program does not have an option for attaching a file. You could use another program such as mutt.
echo "This is the message body" | mutt -a file.to.attach -s "subject of message" [email protected]
Command line options for mutt can be shown with mutt -h
.
The only thing that worked for me in my maven project that was affected by this is to add a "test-compile" goal to the run configuration of my unit tests. Incredibly clumsy solution, but it works.
Global variables that are defined outside of any method or closure can be scope restricted by using the private keyword.
import UIKit
// MARK: Local Constants
private let changeSegueId = "MasterToChange"
private let bookSegueId = "MasterToBook"
The format is as follows:
MINUTE (0-59), HOUR (0-23), DAY (1-31), MONTH (1-12), DAY OF THE WEEK (0-6)
The letter H, representing the word Hash can be inserted instead of any of the values. It will calculate the parameter based on the hash code of you project name.
This is so that if you are building several projects on your build machine at the same time, let’s say midnight each day, they do not all start their build execution at the same time. Each project starts its execution at a different minute depending on its hash code.
You can also specify the value to be between numbers, i.e. H(0,30) will return the hash code of the project where the possible hashes are 0-30.
Examples:
Start build daily at 08:30 in the morning, Monday - Friday: 30 08 * * 1-5
Weekday daily build twice a day, at lunchtime 12:00 and midnight 00:00, Sunday to Thursday: 00 0,12 * * 0-4
Start build daily in the late afternoon between 4:00 p.m. - 4:59 p.m. or 16:00 -16:59 depending on the projects hash: H 16 * * 1-5
Start build at midnight: @midnight or start build at midnight, every Saturday: 59 23 * * 6
Every first of every month between 2:00 a.m. - 02:30 a.m.: H(0,30) 02 01 * *
In Java 9, you can now use Matcher#results()
to get a Stream<MatchResult>
which you can use to get a list/array of matches.
import java.util.regex.Pattern;
import java.util.regex.MatchResult;
String[] matches = Pattern.compile("your regex here")
.matcher("string to search from here")
.results()
.map(MatchResult::group)
.toArray(String[]::new);
// or .collect(Collectors.toList())

"It has the extremely useful property that if all of the edges in a graph are unweighted (or the same weight) then the first time a node is visited is the shortest path to that node from the source node"
Use DateTime
$datetime = new DateTime('tomorrow');
echo $datetime->format('Y-m-d H:i:s');
Or:
$datetime = new DateTime('2013-01-22');
$datetime->modify('+1 day');
echo $datetime->format('Y-m-d H:i:s');
Or:
$datetime = new DateTime('2013-01-22');
$datetime->add(new DateInterval("P1D"));
echo $datetime->format('Y-m-d H:i:s');
Or in PHP 5.4+:
echo (new DateTime('2013-01-22'))->add(new DateInterval("P1D"))
->format('Y-m-d H:i:s');
The whole thing to em is, that the size is relative to the base. So I would say you could keep the font sizes by altering the base.
Example: If you base is 16px, and p is .75em (which is 12px) you would have to raise the base to about 20px. In this case p would then equal about 15px which is the minimum I personally require for mobile phones.
You could also use viewport percentages if you don't care about old school IE.
height: 100vh;
If you are using Nuxt, you can use their dedicated module for this purpose: https://github.com/nuxt-community/google-fonts-module For me it works much better than the webfonts helper, which often had problems downloading the fonts during build and generated CSS files without Unicode ranges.
Learning to use smart pointers is in my opinion one of the most important steps to become a competent C++ programmer. As you know whenever you new an object at some point you want to delete it.
One issue that arise is that with exceptions it can be very hard to make sure a object is always released just once in all possible execution paths.
This is the reason for RAII: http://en.wikipedia.org/wiki/RAII
Making a helper class with purpose of making sure that an object always deleted once in all execution paths.
Example of a class like this is: std::auto_ptr
But sometimes you like to share objects with other. It should only be deleted when none uses it anymore.
In order to help with that reference counting strategies have been developed but you still need to remember addref and release ref manually. In essence this is the same problem as new/delete.
That's why boost has developed boost::shared_ptr, it's reference counting smart pointer so you can share objects and not leak memory unintentionally.
With the addition of C++ tr1 this is now added to the c++ standard as well but its named std::tr1::shared_ptr<>.
I recommend using the standard shared pointer if possible. ptr_list, ptr_dequeue and so are IIRC specialized containers for pointer types. I ignore them for now.
So we can start from your example:
std::vector<gate*> G;
G.push_back(new ANDgate);
G.push_back(new ORgate);
for(unsigned i=0;i<G.size();++i)
{
G[i]->Run();
}
The problem here is now that whenever G goes out scope we leak the 2 objects added to G. Let's rewrite it to use std::tr1::shared_ptr
// Remember to include <memory> for shared_ptr
// First do an alias for std::tr1::shared_ptr<gate> so we don't have to
// type that in every place. Call it gate_ptr. This is what typedef does.
typedef std::tr1::shared_ptr<gate> gate_ptr;
// gate_ptr is now our "smart" pointer. So let's make a vector out of it.
std::vector<gate_ptr> G;
// these smart_ptrs can't be implicitly created from gate* we have to be explicit about it
// gate_ptr (new ANDgate), it's a good thing:
G.push_back(gate_ptr (new ANDgate));
G.push_back(gate_ptr (new ORgate));
for(unsigned i=0;i<G.size();++i)
{
G[i]->Run();
}
When G goes out of scope the memory is automatically reclaimed.
As an exercise which I plagued newcomers in my team with is asking them to write their own smart pointer class. Then after you are done discard the class immedietly and never use it again. Hopefully you acquired crucial knowledge on how a smart pointer works under the hood. There's no magic really.

If you didn't add pip when creating conda environment
conda create -n env_name pip
and also didn't install pip inside the environment
source activate env_name
conda install pip
then the only pip you got is the system pip, which will install packages globally.
Bus as you can see in this issue, even if you did either of the procedure mentioned above, the behavior of pip inside conda environment is still kind of undefined.
To ensure using the pip installed inside conda environment without having to type the lengthy /home/username/anaconda/envs/env_name/bin/pip
, I wrote a shell function:
# Using pip to install packages inside conda environments.
cpip() {
ERROR_MSG="Not in a conda environment."
ERROR_MSG="$ERROR_MSG\nUse \`source activate ENV\`"
ERROR_MSG="$ERROR_MSG to enter a conda environment."
[ -z "$CONDA_DEFAULT_ENV" ] && echo "$ERROR_MSG" && return 1
ERROR_MSG='Pip not installed in current conda environment.'
ERROR_MSG="$ERROR_MSG\nUse \`conda install pip\`"
ERROR_MSG="$ERROR_MSG to install pip in current conda environment."
[ -e "$CONDA_PREFIX/bin/pip" ] || (echo "$ERROR_MSG" && return 2)
PIP="$CONDA_PREFIX/bin/pip"
"$PIP" "$@"
}
Hope this is helpful to you.
I think the poster meant to say You do not have to allocate everything on the
heap
rather than the the stack
.
Basically objects are allocated on the stack (if the object size allows, of course) because of the cheap cost of stack-allocation, rather than heap-based allocation which involves quite some work by the allocator, and adds verbosity because then you have to manage data allocated on the heap.
You can create a new row with $
in your data frame corresponding to the Means
DF$Mean <- rowMeans(DF[,2:4])
Best, Fastest way is
function arrayLookup(array, prop, val) {
for (var i = 0, len = array.length; i < len; i++) {
if (array[i].hasOwnProperty(prop) && array[i][prop] === val) {
return array[i];
}
}
return null;
}
Database Connection:
try {
$conn = mysqli_connect($servername, $username, $password, $db);
//echo "Connected successfully";
} catch (exception $e) {
echo "Connection failed: " . $e->getMessage();
}
Code to read CSV file and upload to table in database.
$file = fopen($filename, "r");
while (($getData = fgetcsv($file, 10000, ",")) !== FALSE) {
$sql = "INSERT into db_table
values ('','" . $getData[1] . "','" . $getData[2] . "','" . $getData[3] . "','" . $getData[4] . "','" . $getData[5] . "','" . $getData[6] . "')";
$result = mysqli_query($conn, $sql);
if (!isset($result)) {
echo "<script type=\"text/javascript\">
alert(\"Invalid File:Please Upload CSV File.
window.location = \"home.do\"
</script>";
} else {
echo "<script type=\"text/javascript\">
alert(\"CSV File has been successfully Imported.\");
window.location = \"home.do\"
</script>";
}
}
fclose($file);
I do like that:
interface XYZ {
x: number;
y: number;
z: number;
}
const a:XYZ = {x:1, y:2, z:3};
const { x, y, ...last } = a;
const { z, ...firstTwo} = a;
console.log(firstTwo, last);
NOTE: didn't test it
int[] concatArray(int[] a, int[] b) {
int[] c = new int[a.length + b.length];
int i = 0;
for (int x : a) { c[i] = x; i ++; }
for (int x : b) { c[i] = x; i ++; }
return c;
}
In Symfony 4, you can use the ParameterBagInterface
:
use Symfony\Component\DependencyInjection\ParameterBag\ParameterBagInterface;
class MessageGenerator
{
private $params;
public function __construct(ParameterBagInterface $params)
{
$this->params = $params;
}
public function someMethod()
{
$parameterValue = $this->params->get('parameter_name');
// ...
}
}
and in app/config/services.yaml
:
parameters:
locale: 'en'
dir: '%kernel.project_dir%'
It works for me in both controller and form classes. More details can be found in the Symfony blog.
ps x | grep SCREEN
to see what is that screen running in case you used the command
screen -A -m -d php make_something.php
The high scoring answer above nailed it.
First you were mixing base 2 and base 10 in your question, then when you put a number on the right side that is not divisible into the base you get problems. Like 1/3 in decimal because 3 doesnt go into a power of 10 or 1/5 in binary which doesnt go into a power of 2.
Another comment though NEVER use equal with floating point numbers, period. Even if it is an exact representation there are some numbers in some floating point systems that can be accurately represented in more than one way (IEEE is bad about this, it is a horrible floating point spec to start with, so expect headaches). No different here 1/3 is not EQUAL to the number on your calculator 0.3333333, no matter how many 3's there are to the right of the decimal point. It is or can be close enough but is not equal. so you would expect something like 2*1/3 to not equal 2/3 depending on the rounding. Never use equal with floating point.
You can have a look at this page showing Deep Folder Copy, it uses recursive means to iterate throught the files and has some really nice tips, like filtering techniques etc.

You can't get the C++ source from an exe, and you can only get some version of the C# source via reflection.
You could use with open("path") as file:
so that it automatically closes, else if it's open in another process you can maybe try
as in Tims example you should use except IOError to not ignore any other problem with your code :)
try:
with open("path", "r") as file: # or just open
# Code here
except IOError:
# raise error or print
Maybe you can try this: though please note - This pulls the column count, not the row count
using (SqlDataReader reader = command.ExecuteReader())
{
while (reader.Read())
{
int count = reader.VisibleFieldCount;
Console.WriteLine(count);
}
}
or if you develop on localhost (only for apache 2.4+):
<If "%{REMOTE_ADDR} != '127.0.0.1'">
</If>
Even though this solution might seem obvious, I just wanted to post it here so the next guy will google it faster.
If you still want to have the model as a parameter in the method, you can create a DelegatingHandler
to buffer the content.
internal sealed class BufferizingHandler : DelegatingHandler
{
protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
await request.Content.LoadIntoBufferAsync();
var result = await base.SendAsync(request, cancellationToken);
return result;
}
}
And add it to the global message handlers:
configuration.MessageHandlers.Add(new BufferizingHandler());
This solution is based on the answer by Darrel Miller.
This way all the requests will be buffered.
To plot just a selection of your columns you can select the columns of interest by passing a list to the subscript operator:
ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)
What you tried was df['V1','V2']
this will raise a KeyError
as correctly no column exists with that label, although it looks funny at first you have to consider that your are passing a list hence the double square brackets [[]]
.
import matplotlib.pyplot as plt
ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)
ax.set_xlabel("Hour", fontsize=12)
ax.set_ylabel("V", fontsize=12)
plt.show()
Summary:
Consider this script, called funcdemo
:
#!/bin/bash
[ $# = 0 ] && exhort "write nastygram"
exhort(){
echo "Please, please do not forget to $*"
}
[ $# != 0 ] && exhort "write begging letter"
In use:
$ funcdemo
./funcdemo: line 3: exhort: command not found
$ funcdemo 1
Please, please do not forget to write begging letter
$
Note the potential for a missing function to lie undiscovered for a long time (think 'by a customer at the most critical wrong moment'). It only matters whether the function exists when it is executed, the same as it only matters whether any other command exists when you try to execute it. Indeed, until it goes to execute the command, the shell neither knows nor cares whether it is an external command or a function.
This applies if you are using it with an authguard
this.router.events.subscribe(event => {
if(event instanceof NavigationStart){
console.log('this is what your looking for ', event.url);
}
}
);
I know I am late to answer this question but I would like to add something to answer of @Ethan, the highest voted and accepted answer.
We can use yargs
to get the command line parameter and with that we can also add our own alias for some parameters like follow.
var args = require('yargs')
.alias('r', 'release')
.alias('d', 'develop')
.default('release', false)
.argv;
Kindly refer this link for more details. https://github.com/yargs/yargs/blob/HEAD/docs/api.md
Following is use of alias as per given in documentation of yargs
. We can also find more yargs
function there and can make the command line passing experience even better.
.alias(key, alias)
Set key names as equivalent such that updates to a key will propagate to aliases and vice-versa.
Optionally .alias() can take an object that maps keys to aliases. Each key of this object should be the canonical version of the option, and each value should be a string or an array of strings.
The difference is not just for Chrome but for most of the web browsers.
F5
refreshes the web page and often reloads the same page from the cached contents of the web browser. However, reloading from cache every time is not guaranteed and it also depends upon the cache expiry.
Shift + F5
forces the web browser to ignore its cached contents and retrieve a fresh copy of the web page into the browser.
Shift + F5
guarantees loading of latest contents of the web page.
However, depending upon the size of page, it is usually slower than F5
.
You may want to refer to: What requests do browsers' "F5" and "Ctrl + F5" refreshes generate?
To get an image from a URL we can use the following code:
ImageIcon imgThisImg = new ImageIcon(PicURL));
jLabel2.setIcon(imgThisImg);
It totally works for me. The PicUrl is a string variable which strores the url of the picture.
By default Chrome extensions do not run in Incognito mode. You have to explicitly enable the extension to run in Incognito.
I am sorry that your concluding question is not that clear but you are wrong from the very first line. The variable data is an Object not an Array
To access the attributes of an object is pretty easy:
alert(data.second);
But, if this does not completely answer your question, please clarify it and post back.
Thanks !
javac only compiles the code. You need to use java command to run the code. The error is because your classpath doesn't contain the class Subclass iwhen you tried to compile it. you need to add them with the -cp variable in javac command
java -cp classpath-entries mainjava arg1 arg2
should run your code with 2 arguments
You must modify the query like this
CREATE TABLE #TMPGUARDIAN(
LAST_NAME NVARCHAR(30),
FRST_NAME NVARCHAR(30))
INSERT INTO #TMPGUARDIAN(FRST_NAME,LAST_NAME)
SELECT LAST_NAME,FRST_NAME FROM TBL_PEOPLE
-- Make a last session for clearing the all temporary tables. always drop at end. In your case, sometimes, there might be an error happen if the table is not exists, while you trying to delete.
DROP TABLE #TMPGUARDIAN
Avoid using insert into Because If you are using insert into then in future if you want to modify the temp table by adding a new column which can be filled after some process (not along with insert). At that time, you need to rework and design it in the same manner.
Use Table Variable http://odetocode.com/articles/365.aspx
declare @userData TABLE(
LAST_NAME NVARCHAR(30),
FRST_NAME NVARCHAR(30)
)
Advantages No need for Drop statements, since this will be similar to variables. Scope ends immediately after the execution.
You can use the contenteditable attribute on the cells, rows, or table in question.
Updated for IE8 compatibility
<table>
<tr><td><div contenteditable>I'm editable</div></td><td><div contenteditable>I'm also editable</div></td></tr>
<tr><td>I'm not editable</td></tr>
</table>
Just note that if you make the table editable, in Mozilla at least, you can delete rows, etc.
You'd also need to check whether your target audience's browsers supported this attribute.
As far as listening for the changes (so you can send to the server), see contenteditable change events
You need Linq - System.Xml.Linq to be precise.
You can create XML using XElement from scratch - that should pretty much sort you out.
I had a similar situation. Here's what I was able to do to get a date range in a "where" clause (a modification of marc_s's answer):
where cast(replace(foo.TestDate, '-', '') as datetime)
between cast('20110901' as datetime) and
cast('20510531' as datetime)
Hope that helps...
To get the maximum value of a column across a set of rows:
SELECT MAX(column1) FROM table; -- expect one result
To get the maximum value of a set of columns, literals, or variables for each row:
SELECT GREATEST(column1, 1, 0, @val) FROM table; -- expect many results
I use the data.table package. With its :=
operator you can :
None of these operations copy the (potentially large) data.table
at all, not even once.
data.table
uses much less working memory.Related links :
It's worth noting, since it's confusing for people new to XML, that the root (or document node) of an XML document is not the top-level element. It's the parent of the top-level element. This is confusing because it doesn't seem like the top-level element can have a parent. Isn't it the top level?
But look at this, a well-formed XML document:
<?xml-stylesheet href="my_transform.xsl" type="text/xsl"?>
<!-- Comments and processing instructions are XML nodes too, remember. -->
<TopLevelElement/>
The root of this document has three children: a processing instruction, a comment, and an element.
So, for example, if you wanted to write a transform that got rid of that comment, but left in any comments appearing anywhere else in the document, you'd add this to the identity transform:
<xsl:template match="/comment()"/>
Even simpler (and more commonly useful), here's an XPath pattern that matches the document's top-level element irrespective of its name: /*
.
$('[data-item-id="stand-out"]')
It also doesn't hurt to watermark your images with Photoshop or even in Lightroom 3 now. Make sure the watermark is clear and in a conspicuous place on your image. That way if it's downloaded, at least you get the advertising!
I could be wrong, but I'm pretty sure that the "interrupt kernel" button just sends a SIGINT signal to the code that you're currently running (this idea is supported by Fernando's comment here), which is the same thing that hitting CTRL+C would do. Some processes within python handle SIGINTs more abruptly than others.
If you desperately need to stop something that is running in iPython Notebook and you started iPython Notebook from a terminal, you can hit CTRL+C twice in that terminal to interrupt the entire iPython Notebook server. This will stop iPython Notebook alltogether, which means it won't be possible to restart or save your work, so this is obviously not a great solution (you need to hit CTRL+C twice because it's a safety feature so that people don't do it by accident). In case of emergency, however, it generally kills the process more quickly than the "interrupt kernel" button.
DF[:-n]
where n is the last number of rows to drop.
To drop the last row :

Best Regards,
Works for Safari, Firefox, and IE7 (haven't tried IE8). Simple test:
<button onclick='$("body,html").scrollTop(0);'> Top </button>
<button onclick='$("body,html").scrollTop(100);'> Middle </button>
<button onclick='$("body,html").scrollTop(250);'> Bottom </button>
Most examples use either one or both, but in reverse order (i.e., "html,body").
Cheers.

Feel free to create 27 layers of abstraction and event binding bloat for your OCD peace of mind.

The mutating method of StringProtocol replacingOccurrences
can be implemented as follow:
extension RangeReplaceableCollection where Self: StringProtocol {
mutating func replaceOccurrences<Target: StringProtocol, Replacement: StringProtocol>(of target: Target, with replacement: Replacement, options: String.CompareOptions = [], range searchRange: Range<String.Index>? = nil) {
self = .init(replacingOccurrences(of: target, with: replacement, options: options, range: searchRange))
}
}
var name = "This is my string"
name.replaceOccurrences(of: " ", with: "+")
print(name) // "This+is+my+string\n"
if (value){
value = (value.length > 1) ? value[0].toUpperCase() + value.substr(1).toLowerCase() : value.toUpperCase();
}
You might want to use TRUNC function on your column when comparing with string format, so it compares only till seconds, not milliseconds.
SELECT * FROM <table_name> WHERE id = 1
AND TRUNC(usagetime, 'SS') = '2012-09-03 08:03:06';
If you wanted to truncate upto minutes, hours, etc. that is also possible, just use appropriate notation instead of 'SS':
hour ('HH'), minute('MI'), year('YEAR' or 'YYYY'), month('MONTH' or 'MM'), Day ('DD')
Rather simple:
Key = i.ToString("D2");
D
stands for "decimal number", 2
for the number of digits to print.
I found an easy solution
Step1. connect to DB with an admin user using PLSQL or sqldeveloper or any other query interface
Step2. run the script bellow; in the S.SQL_TEXT column, you will see the executed queries
SELECT
S.LAST_ACTIVE_TIME,
S.MODULE,
S.SQL_FULLTEXT,
S.SQL_PROFILE,
S.EXECUTIONS,
S.LAST_LOAD_TIME,
S.PARSING_USER_ID,
S.SERVICE
FROM
SYS.V_$SQL S,
SYS.ALL_USERS U
WHERE
S.PARSING_USER_ID=U.USER_ID
AND UPPER(U.USERNAME) IN ('oracle user name here')
ORDER BY TO_DATE(S.LAST_LOAD_TIME, 'YYYY-MM-DD/HH24:MI:SS') desc;
The only issue with this is that I can't find a way to show the input parameters values(for function calls), but at least we can see what is ran in Oracle and the order of it without using a specific tool.
in osx, i installed with brew, here is the setting that works for me
GOPATH="$HOME/my_go_work_space" //make sure you have this folder created
GOROOT="/usr/local/Cellar/go/1.10/libexec"
I have gone through array of solutions and this is what I found to have worked great for me.
In my case I needed to send a post request with some credentials. Small overhead was to add jquery inside the script. But was worth it.
var printPDF = function () {
//prevent double sending
var sendz = {};
sendz.action = "Print";
sendz.url = "api/Print";
jQuery('<form action="' + sendz.url + '" method="POST">' +
'<input type="hidden" name="action" value="Print" />'+
'<input type="hidden" name="userID" value="'+$scope.user.userID+'" />'+
'<input type="hidden" name="ApiKey" value="' + $scope.user.ApiKey+'" />'+
'</form>').appendTo('body').submit().remove();
}
For multi-line content jade normally uses a "|", however:
Tags that accept only text such as script, style, and textarea do not need the leading | character
This said, i cannot reproduce the problem you are having. When i paste that code in a jade template, it produces the right output and prompts me with an alert on page-load.
There is an issue when you use DateFormatSymbols class for its getMonthName method to get Month by Name it show Month by Number in some Android devices. I have resolved this issue by doing this way:
In String_array.xml
<string-array name="year_month_name">
<item>January</item>
<item>February</item>
<item>March</item>
<item>April</item>
<item>May</item>
<item>June</item>
<item>July</item>
<item>August</item>
<item>September</item>
<item>October</item>
<item>November</item>
<item>December</item>
</string-array>
In Java class just call this array like this way:
public String[] getYearMonthName() {
return getResources().getStringArray(R.array.year_month_names);
//or like
//return cntx.getResources().getStringArray(R.array.month_names);
}
String[] months = getYearMonthName();
if (i < months.length) {
monthShow.setMonthName(months[i] + " " + year);
}
Happy Coding :)
Below Code only works if It contain Unique Value Data
public string getKey(string Value)
{
if (dictionary.ContainsValue(Value))
{
var ListValueData=new List<string>();
var ListKeyData = new List<string>();
var Values = dictionary.Values;
var Keys = dictionary.Keys;
foreach (var item in Values)
{
ListValueData.Add(item);
}
var ValueIndex = ListValueData.IndexOf(Value);
foreach (var item in Keys)
{
ListKeyData.Add(item);
}
return ListKeyData[ValueIndex];
}
return string.Empty;
}
Although there is an accepted answer I don't feel that it is the right one. It is the simplest way to achieve what is needed, but even if already enabled in InnoDB (actually docs tell you that you still should get NULL ...), if you read MySQL docs, even in current version (8.0) using UPDATE_TIME is not the right option, because:
Timestamps are not persisted when the server is restarted or when the table is evicted from the InnoDB data dictionary cache.
If I understand correctly (can't verify it on a server right now), timestamp gets reset after server restart.
As for real (and, well, costly) solutions, you have Bill Karwin's solution with CURRENT_TIMESTAMP and I'd like to propose a different one, that is based on triggers (I'm using that one).
You start by creating a separate table (or maybe you have some other table that can be used for this purpose) which will work like a storage for global variables (here timestamps). You need to store two fields - table name (or whatever value you'd like to keep here as table id) and timestamp. After you have it, you should initialize it with this table id + starting date (NOW() is a good choice :) ).
Now, you move to tables you want to observe and add triggers AFTER INSERT/UPDATE/DELETE with this or similar procedure:
CREATE PROCEDURE `timestamp_update` ()
BEGIN
UPDATE `SCHEMA_NAME`.`TIMESTAMPS_TABLE_NAME`
SET `timestamp_column`=DATE_FORMAT(NOW(), '%Y-%m-%d %T')
WHERE `table_name_column`='TABLE_NAME';
END
this is how I fix this issue
1.open my project structure
2.click module
3.click plus button
4.click import module,and find the module's pom
5.make sure you select the module you want to import,then next next finish:)
all Values is always taken with .val()
.
see the code bellow:
var message = $('#message').val();
The cleanest way to work with it. Assuming your table is a list of integers called "dbo.tvp_Int" (Customize for your own table type)
Create this extension method...
public static void AddWithValue_Tvp_Int(this SqlParameterCollection paramCollection, string parameterName, List<int> data)
{
if(paramCollection != null)
{
var p = paramCollection.Add(parameterName, SqlDbType.Structured);
p.TypeName = "dbo.tvp_Int";
DataTable _dt = new DataTable() {Columns = {"Value"}};
data.ForEach(value => _dt.Rows.Add(value));
p.Value = _dt;
}
}
Now you can add a table valued parameter in one line anywhere simply by doing this:
cmd.Parameters.AddWithValueFor_Tvp_Int("@IDValues", listOfIds);
I faced this problem lately, and tried all suggestions above, and problem was not saved. Finally I changed a NDK, and problem was solved...
Use union
as follows:
val sc = new SparkContext(...)
val r1 = sc.textFile("xxx1")
val r2 = sc.textFile("xxx2")
...
val rdds = Seq(r1, r2, ...)
val bigRdd = sc.union(rdds)
Then the bigRdd
is the RDD with all files.
According to Java Persistence with Hibernate
mapping collections of value types with annotations [...]. At the time of writing it isn't part of the Java Persistence standard
If you were using Hibernate, you could do something like:
@org.hibernate.annotations.CollectionOfElements(
targetElement = java.lang.String.class
)
@JoinTable(
name = "foo",
joinColumns = @JoinColumn(name = "foo_id")
)
@org.hibernate.annotations.IndexColumn(
name = "POSITION", base = 1
)
@Column(name = "baz", nullable = false)
private List<String> arguments = new ArrayList<String>();
Update: Note, this is now available in JPA2.
@Jon: Jon, are you saying using multiple where clauses e.g.
var query = from r in tempData.AsEnumerable()
where r.Field<string>("UserName") != "XXXX"
where r.Field<string>("UserName") != "YYYY"
select r;
is more restictive than using
var query = from r in tempData.AsEnumerable()
where r.Field<string>("UserName") != "XXXX" && r.Field<string>("UserName") != "YYYY"
select r;
I think they are equivalent as far as the result goes.
However, I haven't tested, if using multiple where in the first example cause in 2 subqueries, i.e. .Where(r=>r.UserName!="XXXX").Where(r=>r.UserName!="YYYY)
or the LINQ translator is smart enought to execute .Where(r=>r.UserName!="XXXX" && r.UsernName!="YYYY")
Here is a solution I came up with for myself. This is ready to run as a command prompt project. You need to clean some stuff if not. Hope this helps. It accepts several input formats like: 1.234.567,89 1,234,567.89 etc

{
while(true)
{
// reads input number from keyboard
string input = Console.ReadLine();
double result = 0;
// remove empty spaces
input = input.Replace(" ", "");
// checks if the string is empty
if (string.IsNullOrEmpty(input) == false)
{
// check if input has , and . for thousands separator and decimal place
if (input.Contains(",") && input.Contains("."))
{
// find the decimal separator, might be , or .
int decimalpos = input.LastIndexOf(',') > input.LastIndexOf('.') ? input.LastIndexOf(',') : input.LastIndexOf('.');
// uses | as a temporary decimal separator
input = input.Substring(0, decimalpos) + "|" + input.Substring(decimalpos + 1);
// formats the output removing the , and . and replacing the temporary | with .
input = input.Replace(".", "").Replace(",", "").Replace("|", ".");
}
// replaces , with .
if (input.Contains(","))
{
input = input.Replace(',', '.');
}
// checks if the input number has thousands separator and no decimal places
if(input.Count(item => item == '.') > 1)
{
input = input.Replace(".", "");
}
// tries to convert input to double
if (double.TryParse(input, out result) == true)
{
result = Double.Parse(input, NumberStyles.AllowLeadingSign | NumberStyles.AllowDecimalPoint | NumberStyles.AllowThousands, CultureInfo.InvariantCulture);
}
}
// outputs the result
Console.WriteLine(result.ToString());
Console.WriteLine("----------------");
}
}
}
}
My main advice would be to steer clear of the HAVING
clause (see below):
WITH HighEarners AS
( SELECT EmpId, DeptId
FROM EMPLOYEE
WHERE Salary > 1000 ),
DeptmentHighEarnerTallies AS
( SELECT DeptId, COUNT(*) AS HighEarnerTally
FROM HighEarners
GROUP
BY DeptId )
SELECT DeptName
FROM DEPARTMENT NATURAL JOIN DeptmentHighEarnerTallies
WHERE HighEarnerTally > 2;
The very early SQL implementations lacked derived tables and HAVING
was a workaround for one of its most obvious drawbacks (how to select on the result of a set function from the SELECT
clause). Once derived tables had become a thing, the need for HAVING
went away. Sadly, HAVING
itself didn't go away (and never will) because nothing is ever removed from standard SQL. There is no need to learn HAVING
and I encourage fledgling coders to avoid using this historical hangover.
compile function -
syntax
function compile(tElement, tAttrs, transclude) { ... }
controller
pre - link
The link function is responsible for registering DOM listeners as well as updating the DOM. It is executed after the template has been cloned. This is where most of the directive logic will be put.
You can update the dom in the controller using angular.element but this is not recommended as the element is provided in the link function
Pre-link function is used to implement logic that runs when angular js has already compiled the child elements but before any of the child element's post link have been called
post-link
directive that only has link function, angular treats the function as a post link
post will be executed after compile, controller and pre-link funciton, so that's why this is considered the safest and default place to add your directive logic

Now navigation looks like that:
Settings -> General -> Device Management -> Tap on necessary profile in list -> Trust.
For ExpressJs router:
router.post('/login', async(req, res) => {
return res.send({redirect: '/yoururl'});
})
Client-side:
success: function (response) {
if (response.redirect) {
window.location = response.redirect
}
},
It could be because the function above it is not indented the same way. i.e.
class a:
def blah:
print("Hello world")
def blah1:
print("Hello world")
You could use an XPath, too. A bit old fashioned but still effective:
using System.Xml;
...
XmlDocument xmlDocument;
xmlDocument = new XmlDocument();
xmlDocument.LoadXml(xml);
foreach (XmlElement xmlElement in
xmlDocument.DocumentElement.SelectNodes("word[category='verb']"))
{
Console.Out.WriteLine(xmlElement.OuterXml);
}
Try this it worked for me.

Remove cascading from the child entity Transaction
, it should be just:
@Entity class Transaction {
@ManyToOne // no cascading here!
private Account account;
}
(FetchType.EAGER
can be removed as well as it's the default for @ManyToOne
)
That's all!
Why? By saying "cascade ALL" on the child entity Transaction
you require that every DB operation gets propagated to the parent entity Account
. If you then do persist(transaction)
, persist(account)
will be invoked as well.
But only transient (new) entities may be passed to persist
(Transaction
in this case). The detached (or other non-transient state) ones may not (Account
in this case, as it's already in DB).
Therefore you get the exception "detached entity passed to persist". The Account
entity is meant! Not the Transaction
you call persist
on.
You generally don't want to propagate from child to parent. Unfortunately there are many code examples in books (even in good ones) and through the net, which do exactly that. I don't know, why... Perhaps sometimes simply copied over and over without much thinking...
Guess what happens if you call remove(transaction)
still having "cascade ALL" in that @ManyToOne? The account
(btw, with all other transactions!) will be deleted from the DB as well. But that wasn't your intention, was it?
Just add a question mark ?

We are using HTTPClient 4.3.5 and we tried almost all solutions exist on the stackoverflow but nothing, After thinking and figuring out the problem, we come to the following code which works perfectly, just add it before creating HttpClient instance.
some method to call when making post requests....
SSLContextBuilder builder = new SSLContextBuilder();
builder.loadTrustMaterial(null, new TrustStrategy() {
@Override
public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
return true;
}
});
SSLConnectionSocketFactory sslSF = new SSLConnectionSocketFactory(builder.build(),
SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
HttpClient httpClient = HttpClients.custom().setSSLSocketFactory(sslSF).build();
HttpPost postRequest = new HttpPost(url);
continue your request in the normal form
You need to do a deep copy from user to usercopy, and then after your login you can reassign your userCopy reference to user.
User userCopy = new User();
userCopy.Age = user.Age
userCopy.ID = user.ID
foreach(...)
{
user.Age = 1;
user.ID = -1;
UserDao.Update(user)
user = userCopy;
}
One more case is that You only can collate with instanceof
- it returns true or false. With typeof
you can get type of provided something
I write below code to remove the blank value in the array string.
string[] test={"1","","2","","3"};
test= test.Except(new List<string> { string.Empty }).ToArray();
I would go with
i = np.min(np.where(V >= x))
where V
is vector (1d array), x
is the value and i
is the resulting index.

Sub Results2()
Dim rCell As Range
Dim shSource As Worksheet
Dim shDest As Worksheet
Dim lCnt As Long
Set shSource = ThisWorkbook.Sheets("Sheet1")
Set shDest = ThisWorkbook.Sheets("Sheet2")
For Each rCell In shSource.Range("A1", shSource.Cells(shSource.Rows.Count, 1).End(xlUp)).Cells
lCnt = lCnt + 1
shDest.Range("A4").Offset(0, lCnt * 4).Formula = "=" & rCell.Address(False, False, , True) & "+" & rCell.Offset(0, 1).Address(False, False, , True)
Next rCell
End Sub
This loops through column A of sheet1 and creates a formula in sheet2 for every cell. To find the last cell in Sheet1, I start at the bottom (shSource.Rows.Count) and .End(xlUp) to get the last cell in the column that's not blank.
To create the elements of the formula, I use the Address property of the cell on Sheet. I'm using three of the arguments to Address. The first two are RowAbsolute and ColumnAbsolute, both set to false. I don't care about the third argument, but I set the fourth argument (External) to True so that it includes the sheet name.
I prefer to go from Source to Destination rather than the other way. But that's just a personal preference. If you want to work from the destination,
Sub Results3()
Dim i As Long, lCnt As Long
Dim sh As Worksheet
lCnt = Application.WorksheetFunction.CountA(ThisWorkbook.Sheets("Sheet1").Columns(1))
Set sh = ThisWorkbook.Sheets("Sheet2")
Const sSOURCE As String = "Sheet1!"
For i = 1 To lCnt
sh.Range("A1").Offset(0, 4 * (i - 1)).Formula = "=" & sSOURCE & "A" & i & " + " & sSOURCE & "B" & i
Next i
End Sub
You can do:
<form action="" method="post">
<table>
{% for field in form %}
<tr><td>{{field}}</td></tr>
{% endfor %}
</table>
<input type="submit" value="Submit">
</form>
Then you can add classes/id's to for example the <td>
tag. You can of course use any others tags you want. Check Working with Django forms as an example what is available for each field
in the form ({{field}}
for example is just outputting the input tag, not the label and so on).
As per your question,
List<Double> frameList = new ArrayList<Double>();
First you have to convert List<Double>
to Double[]
by using
Double[] array = frameList.toArray(new Double[frameList.size()]);
Next you can convert Double[]
to double[]
using
double[] doubleArray = ArrayUtils.toPrimitive(array);
You can directly use it in one line:
double[] array = ArrayUtils.toPrimitive(frameList.toArray(new Double[frameList.size()]));
You need to use bitwise operators |
instead of or
and &
instead of and
in pandas, you can't simply use the bool statements from python.
For much complex filtering create a mask
and apply the mask on the dataframe.
Put all your query in the mask and apply it.
Suppose,
mask = (df["col1"]>=df["col2"]) & (stock["col1"]<=df["col2"])
df_new = df[mask]
That's because Chrome added support for source maps.
Go to the developer tools (F12 in the browser), then select the three dots in the upper right corner, and go to Settings.
Then, look for Sources, and disable the options: "Enable javascript source maps" "Enable CSS source maps"
If you do that, that would get rid of the warnings. It has nothing to do with your code. Check the developer tools in other pages and you will see the same warning.
From what I understand, you have your data on a table and you want to create the CSV from that data. However, you have problem creating the CSV.
My thoughts would be to iterate and parse the contents of the table and generate a string from the parsed data. You can check How to convert JSON to CSV format and store in a variable for an example. You are using jQuery in your example so that would not count as an external plugin. Then, you just have to serve the resulting string using window.open
and use application/octetstream
as suggested.

itself and watch out for boolean and scalar types. Don't be too discouraged if it's not intuitive or easy, it's a pain at first.

Found this out by trial and error. If your configuration specifies a ServerName, then your VirtualHost directive will need to do the same. In the following example, awesome.example.com and amazing.example.com would both be forwarded to some local service running on port 4567.
ServerName example.com:80
<VirtualHost example.com:80>
ProxyPreserveHost On
ProxyRequests Off
ServerName awesome.example.com
ServerAlias amazing.example.com
ProxyPass / http://localhost:4567/
ProxyPassReverse / http://localhost:4567/
</VirtualHost>
I know this doesn't exactly answer the question, but I'm putting it here because this is the top search result for Apache port forwarding. So I figure it'll help somebody someday.
I was tying to figure out how to do this but i could not get any answers from google. I know this is an old thread but here was my solution:
Use the following class:
class ThreadWaiter
{
private int _numThreads = 0;
private int _spinTime;
public ThreadWaiter(int SpinTime)
{
this._spinTime = SpinTime;
}
public void AddThreads(int numThreads)
{
_numThreads += numThreads;
}
public void RemoveThread()
{
if (_numThreads > 0)
{
_numThreads--;
}
}
public void Wait()
{
while (_numThreads != 0)
{
System.Threading.Thread.Sleep(_spinTime);
}
}
}
You should add following lines while creating a project. It will always ignore .DS_Store
to be pushed to the repository.
*.DS_Store
this will ignore .DS_Store while code commit.
git rm --cached .DS_Store
this is to remove .DS_Store files from your repository, in case you need it, you can uncomment it.
## ignore .DS_Store file.
# git rm --cached .DS_Store
*.DS_Store
git reset --hard <tag/branch/commit id>
Notes:
git reset
without the --hard
option resets the commit history, but not the files. With the --hard
option the files in working tree are also reset. (credited user)
If you wish to commit that state so that the remote repository also points to the rolled back commit do: git push <reponame> -f

In entity relationship modeling, solid lines represent strong relationships and dashed lines represent weak relationships.
I think is this a very simple way with regards to all solutions above:
const elm = document.getElementById("myElement")
const allMyStyle = [
{ prop: "position", value: "fixed" },
{ prop: "boxSizing", value: "border-box" },
{ prop: "opacity", value: 0.9 },
{ prop: "zIndex", value: 1000 },
];
allMyStyle.forEach(({ prop, value }) => {
elm.style[prop] = value;
});

ls -tQ | tail -n+4 | xargs rm
List filenames by modification time, quoting each filename. Exclude first 3 (3 most recent). Remove remaining.
EDIT after helpful comment from mklement0 (thanks!): corrected -n+3 argument, and note this will not work as expected if filenames contain newlines and/or the directory contains subdirectories.
As Lattyware said, there is a difference between Python2 & Python3 that leads to this error:
With Python2, int(str(5/2))
gives you 2.
With Python3, the same gives you: ValueError: invalid literal for int() with base 10: '2.5'
If you need to convert some string that could contain float instead of int, you should always use the following ugly formula:
int(float(myStr))
As float('3.0')
and float('3')
give you 3.0, but int('3.0')
gives you the error.
<head>
<script type="text/javascript">
function SetMaxLength () {
var input = document.getElementById("myInput");
input.maxLength = 10;
}
</script>
</head>
<body>
<input id="myInput" type="text" size="20" />
</body>
You should use setTimestamp instead, if you hardcode it:
$start_date = new DateTime();
$start_date->setTimestamp(1372622987);
in your case
$start_date = new DateTime();
$start_date->setTimestamp($dbResult->db_timestamp);

You can set the dir variable with any start directory you want or used the current directory (%cd%) variable.

Several answers here suggest using datetime.datetime.strptime
to parse RFC 3339 or ISO 8601 datetimes with timezones, like the one exhibited in the question:
2008-09-03T20:56:35.450686Z
This is a bad idea.
Assuming that you want to support the full RFC 3339 format, including support for UTC offsets other than zero, then the code these answers suggest does not work. Indeed, it cannot work, because parsing RFC 3339 syntax using strptime
is impossible. The format strings used by Python's datetime module are incapable of describing RFC 3339 syntax.
The problem is UTC offsets. The RFC 3339 Internet Date/Time Format requires that every date-time includes a UTC offset, and that those offsets can either be Z
(short for "Zulu time") or in +HH:MM
or -HH:MM
format, like +05:00
or -10:30
.
Consequently, these are all valid RFC 3339 datetimes:
2008-09-03T20:56:35.450686Z
2008-09-03T20:56:35.450686+05:00
2008-09-03T20:56:35.450686-10:30
Alas, the format strings used by strptime
and strftime
have no directive that corresponds to UTC offsets in RFC 3339 format. A complete list of the directives they support can be found at https://docs.python.org/3/library/datetime.html#strftime-and-strptime-behavior, and the only UTC offset directive included in the list is %z
:
%z
UTC offset in the form +HHMM or -HHMM (empty string if the the object is naive).
Example: (empty), +0000, -0400, +1030
This doesn't match the format of an RFC 3339 offset, and indeed if we try to use %z
in the format string and parse an RFC 3339 date, we'll fail:
>>> from datetime import datetime
>>> datetime.strptime("2008-09-03T20:56:35.450686Z", "%Y-%m-%dT%H:%M:%S.%f%z")

ValueError: time data '2008-09-03T20:56:35.450686Z' does not match format '%Y-%m-%dT%H:%M:%S.%f%z'

ValueError: time data '2008-09-03T20:56:35.450686+05:00' does not match format '%Y-%m-%dT%H:%M:%S.%f%z'
(Actually, the above is just what you'll see in Python 3. In Python 2 we'll fail for an even simpler reason, which is that strptime
does not implement the %z
directive at all in Python 2.)
The multiple answers here that recommend strptime
all work around this by including a literal Z
in their format string, which matches the Z
from the question asker's example datetime string (and discards it, producing a datetime
object without a timezone):
>>> datetime.strptime("2008-09-03T20:56:35.450686Z", "%Y-%m-%dT%H:%M:%S.%fZ")
datetime.datetime(2008, 9, 3, 20, 56, 35, 450686)
Since this discards timezone information that was included in the original datetime string, it's questionable whether we should regard even this result as correct. But more importantly, because this approach involves hard-coding a particular UTC offset into the format string, it will choke the moment it tries to parse any RFC 3339 datetime with a different UTC offset:
>>> datetime.strptime("2008-09-03T20:56:35.450686+05:00", "%Y-%m-%dT%H:%M:%S.%fZ")
Traceback (most recent call last):

tt, fraction = _strptime(data_string, format)

ValueError: time data '2008-09-03T20:56:35.450686+05:00' does not match format '%Y-%m-%dT%H:%M:%S.%fZ'
Unless you're certain that you only need to support RFC 3339 datetimes in Zulu time, and not ones with other timezone offsets, don't use strptime
. Use one of the many other approaches described in answers here instead.

There are a number of different ways you could do this. To begin with, matplotlib
will automatically cycle through colors. By default, it cycles through blue, green, red, cyan, magenta, yellow, black:
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 1, 10)
for i in range(1, 6):
plt.plot(x, i * x + i, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()
If you want to control which colors matplotlib cycles through, use ax.set_color_cycle
:
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 1, 10)
fig, ax = plt.subplots()
ax.set_color_cycle(['red', 'black', 'yellow'])
for i in range(1, 6):
plt.plot(x, i * x + i, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()
If you'd like to explicitly specify the colors that will be used, just pass it to the color
kwarg (html colors names are accepted, as are rgb tuples and hex strings):
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 1, 10)
for i, color in enumerate(['red', 'black', 'blue', 'brown', 'green'], start=1):
plt.plot(x, i * x + i, color=color, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()
Finally, if you'd like to automatically select a specified number of colors from an existing colormap:
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 1, 10)
number = 5
cmap = plt.get_cmap('gnuplot')
colors = [cmap(i) for i in np.linspace(0, 1, number)]
for i, color in enumerate(colors, start=1):
plt.plot(x, i * x + i, color=color, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()
The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:
ffmpeg -i input.mov -qscale 0 output.mp4
Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0
):
ffmpeg -i input.mov -q:v 0 output.mp4
If you just want to use MonthName then reference Microsoft.VisualBasic and it's in Microsoft.VisualBasic.DateAndTime
//eg. Get January
String monthName = Microsoft.VisualBasic.DateAndTime.MonthName(1);
I had a similar problem. In my case, I had accidentally included winuser.h
before windows.h
(actually, a buggy IDE extension had added it). Removing the winuser.h
solved the problem.
I did everything above but had to do one more thing in IntelliJ:
Project Structure > Modules
I had to change every module's "language level"
$IP_Array = (Get-Content test2.csv)[0].split(",")
foreach ( $IP in $IP_Array){
$IP
}
Get-content Filename returns an array of strings for each line.
On the first string only, I split it based on ",". Dumping it into $IP_Array.
$IP_Array = (Get-Content test2.csv)[0].split(",")
foreach ( $IP in $IP_Array){
if ($IP -eq "2.2.2.2") {
Write-Host "Found $IP"
}
}
For the replacement string and the replacement pattern as specified by $
.
here a resume:
link to doc : here
"hello _there_".replace(/_(.*?)_/g, "<div>$1</div>")
Note:
If you want to have a $
in the replacement string use $$
. Same as with vscode snippet system.

For single value the datetime.strptime
method is the fastest
import arrow
from datetime import datetime
import pandas as pd
l = ['24052010']
%timeit _ = list(map(lambda x: datetime.strptime(x, '%d%m%Y').date(), l))
6.86 µs ± 56.5 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)
%timeit _ = list(map(lambda x: x.date(), pd.to_datetime(l, format='%d%m%Y')))
305 µs ± 6.32 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
%timeit _ = list(map(lambda x: arrow.get(x, 'DMYYYY').date(), l))
46 µs ± 978 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)
For a list of values the pandas pd.to_datetime
is the fastest
l = ['24052010'] * 1000
%timeit _ = list(map(lambda x: datetime.strptime(x, '%d%m%Y').date(), l))
6.32 ms ± 89.6 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
%timeit _ = list(map(lambda x: x.date(), pd.to_datetime(l, format='%d%m%Y')))
1.76 ms ± 27.3 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
%timeit _ = list(map(lambda x: arrow.get(x, 'DMYYYY').date(), l))
44.5 ms ± 522 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
For ISO8601 datetime format the ciso8601
is a rocket
import ciso8601
l = ['2010-05-24'] * 1000
%timeit _ = list(map(lambda x: ciso8601.parse_datetime(x).date(), l))
241 µs ± 3.24 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
A simple way is to make your own log collector methods or even just an existing log collector app from the market.
For my apps I made a report functionality which sends the logs to my email (or even to another place - once you get the log you can do whether you want with it).
Here is a simple example about how to get the log file from a device:
import time
time.strftime('%H:%M%p %Z on %b %d, %Y')
if you used vue-cli and webpack when you created your project.
you can use just
npm run build command in command line, and it will create dist folder in your project. Just upload content of this folder to your ftp and done.
I had the same problem. I closed terminal and restarted node. This worked for me.
Google has added a new feature since the last answer was posted here.

I like @Alex Howansky have used 'cmp --silent' for this. But I need both positive and negative response so I use:
cmp --silent file1 file2 && echo '### SUCCESS: Files Are Identical! ###' || echo '### WARNING: Files Are Different! ###'
I can then run this in the terminal or with a ssh to check files against a constant file.
If you only want the orientation tag and nothing else and don't like to include another huge javascript library I wrote a little code that extracts the orientation tag as fast as possible (It uses DataView and readAsArrayBuffer

return array(key($array) => array_pop($array));
will return exactly as the example in the question.
You need to start by understanding that the target of a symlink is a pathname. And it can be absolute or relative to the directory which contains the symlink
Assuming you have foo.conf in sites-available
Try
cd sites-enabled
sudo ln -s ../sites-available/foo.conf .
ls -l
Now you will have a symlink in sites-enabled called foo.conf which has a target ../sites-available/foo.conf
Just to be clear, the normal configuration for Apache is that the config files for potential sites live in sites-available and the symlinks for the enabled sites live in sites-enabled, pointing at targets in sites-available. That doesn't quite seem to be the case the way you describe your setup, but that is not your primary problem.
If you want a symlink to ALWAYS point at the same file, regardless of the where the symlink is located, then the target should be the full path.
ln -s /etc/apache2/sites-available/foo.conf mysimlink-whatever.conf
Here is (line 1 of) the output of my ls -l /etc/apache2/sites-enabled:
lrwxrwxrwx 1 root root 26 Jun 24 21:06 000-default -> ../sites-available/default
See how the target of the symlink is relative to the directory that contains the symlink (it starts with ".." meaning go up one directory).
Hardlinks are totally different because the target of a hardlink is not a directory entry but a filing system Inode.
Annotate other components with @Component, for example REST Resource classes.
@Component
public class AdressComp{
.......
...//some code here
}
@Component is a generic stereotype for any Spring managed component.
@Controller, @Service and @Repository are Specializations of @Component for specific use cases.
While the chosen answer is correct and more concise, I'd argue for the structure noted in other answers:
SELECT * FROM your_table
WHERE UNIX_TIMESTAMP(DateVisited) >= UNIX_TIMESTAMP(CAST(NOW() - INTERVAL 1 DAY AS DATE))
AND UNIX_TIMESTAMP(DateVisited) <= UNIX_TIMESTAMP(CAST(NOW() AS DATE));
If you just need a bare date without timestamp you could also write it as the following:
SELECT * FROM your_table
WHERE DateVisited >= CAST(NOW() - INTERVAL 1 DAY AS DATE)
AND DateVisited <= CAST(NOW() AS DATE);
The reason for using CAST
versus SUBDATE
is CAST
is ANSI SQL syntax. SUBDATE
is a MySQL specific implementation of the date arithmetic component of CAST
. Getting into the habit of using ANSI syntax can reduce headaches should you ever have to migrate to a different database. It's also good to be in the habit as a professional practice as you'll almost certainly work with other DBMS' in the future.
None of the major DBMS systems are fully ANSI compliant, but most of them implement the broad set of ANSI syntax whereas nearly none of them outside of MySQL and its descendants (MariaDB, Percona, etc) will implement MySQL-specific syntax.
In case of find
, it's probably easiest to just give the absolute path for it to search in, e.g.:
find /etc
find `pwd`/subdir_of_current_dir/ -type f
Came across this question just now and have something to add
To go to the most recent commit:
git checkout $(git log --branches -1 --pretty=format:"%H")
Explanation:
git log --branches
shows log of commits from all local branches
-1
limit to one commit → most recent commit
--pretty=format:"%H"
format to only show commit hash
git checkout $(...)
use output of subshell as argument for checkout
Note:
This will result in a detached head though (because we checkout directly to the commit). This can be avoided by extracting the branch name using sed
, explained below.
To go to the branch of the most recent commit:
git checkout $(git log --branches -1 --pretty=format:'%D' | sed 's/.*, //g')
Explanation:
git log --branches
shows log of commits from all local branches
-1
limit to one commit → most recent commit
--pretty=format:"%D"
format to only show ref names
| sed 's/.*, //g'
ignore all but the last of multiple refs (*)
git checkout $(...)
use output of subshell as argument for checkout
*) HEAD and remote branches are listed first, local branches are listed last in alphabetically descending order, so the one remaining will be the alphabetically first branch name
Note:
This will always only use the (alphabetically) first branch name if there are multiple for that commit.
Anyway, I think the best solution would just be to display the ref names for the most recent commit to know where to checkout to:
git log --branches -1 --pretty=format:'%D'
E.g. create the alias git top
for that command.
I believe telnet 74.255.12.25 8089
. Why don't u try both
