d501 | train | When you divide $valueAsCents = 54780 / 100 then it becomes a float which is not always accurate in digital form because of the way they are stored. In my tests I got
547.7999999999999545252649113535881042480468750000
When multiplied by 100 this is would be
54779.9999999999927240423858165740966796870000
When PHP casts to int, it always rounds down.
When converting from float to integer, the number will be rounded towards zero.
This is why the int value is 54779
Additionally, the PHP manual for float type also includes a hint that floating point numbers may not do what you expect.
Additionally, rational numbers that are exactly representable as floating point numbers in base 10, like 0.1 or 0.7, do not have an exact representation as floating point numbers in base 2, which is used internally, no matter the size of the mantissa. Hence, they cannot be converted into their internal binary counterparts without a small loss of precision. This can lead to confusing results: for example, floor((0.1+0.7)*10) will usually return 7 instead of the expected 8, since the internal representation will be something like 7.9999999999999991118.... | unknown | |
d502 | train | You need to bind to a list of int instead of a list of Label on your view model. Then, you'll need to use that list of selected ids to fill your list of labels on the Team entity you're persisting:
public class CreateTeamViewModel
{
[Required]
public string TeamName { get; set; }
public string ProjectName { get; set; }
public string ProjectDescription { get; set; }
[Required]
public string RepositoryLink { get; set; }
public List<int> SelectedLabels { get; set; } = new List<int>();
}
Then, you'll need to modify your form to bind your checkboxes to this list:
@foreach (var label in labels)
{
<input asp-for="SelectedLabels" id="Label@(label.Id)" value="@label.Id" type="checkbox" />
<label id="Label@(label.Id)">
<span class="badge badge-@label.ColorPalette">@label.Name</span>
</label>
}
Notice that I removed the hidden inputs. You should never post anything that the user should not be able to modify, as even hidden inputs can be tampered with.
After posting, server-side you'll end up with a list of label ids that were selected by the user. Simply query the associated labels out of your database and then assign that to the team you're creating:
team.Labels = await _context.Set<Label>().Where(x => model.SelectedLabels.Contains(x.Id)).ToListAsync(); | unknown | |
d503 | train | You need to use as below
MenuItem menuTest2 = new MenuItem(); // Main Manu 2
menuTest2.Text = " SMS ";
menuTest2.NavigateUrl = "javascript:void(0)";
//menuTest2.Value = "something";
Menu1.Items.Add(menuTest2);
The problem as I think was that the page get redirected to the same page when clicked. And as I guess the menu is created on page load event.
Using menuTest2.NavigateUrl = "javascript:void(0)"; will stop the menu to postback when it is clicked. | unknown | |
d504 | train | If it is a logical column, no need to == TRUE. Also, when subsetting a single column, directly subset instead of subsetting it from the data.frame which is inefficient
x[(x$a %in% y$b | x$a %in% y$d[y$c]), ]
Or make it a bit more compact
x[(x$a %in% c(y$b, y$d[y$c])),]
A: It might be worth to give subset a try.
subset(x, a %in% b | a %in% y[y$c, 'd']) | unknown | |
d505 | train | How about using YCbCr?
Y is intensity, Cb is the blue component relative to the green component and Cr is the red component relative to the green component.

d510 | train | As you are already iterating from end to start you can just append the characters to the fresh and empty string builder. setChar() is only intended to replace existing characters.

String str = "Shubham";
StringBuilder str2 = new StringBuilder();
for (int i = str.length() - 1; i >= 0; i--) {
str2.append(str.charAt(i));
}
System.out.println(str2.toString());
}
}
gives
$ java StringBuilders.java
mahbuhS
A: You haven't declared a value to the str2 string.
The for loop is trying to find a character at index j=0 in str2 to set value i of str2, which it cannot find.
Hence the error.
For this to work, you need declare a value of str2 to a length >= str1. i.e., if str1 = "0123456", str2 should be at least 0123456 or more.
Instead of using StringBuilder to set the char, you can use String to just append to it.
String str1 = new String("Shubham");
String str2 = new String();
int iter = str1.length() -1;
for(int i=iter; i>=0; i--) {
str2 += str1.charAt(i);
}

d511 | train | Refer this great write up: http://blog.webbb.be/command-not-found-node-npm/
This can happen when npm is installing to a location that is not the standard and is not in your path.
To check where npm is installing, run: npm root -g
It SHOULD say /usr/local/lib/node_modules, If it doesn't then follow this:
Set it to the correct PATH:
*
*run: npm config set prefix /usr/local
*Then reinstall your npm package(s) with -g:
npm install -g cordova etc
If this doesn't work then try adding the global path of cordova(where it got installed) to your $PATH variable. | unknown | |
d512 | train | This is not REST.
REST is about using HTTP, not XML!
A typical HTTP REQUEST to create an item would be like this
PUT http://mysite/items/ HTTP/1.1
Host: xxxxx
<myitem>
<text> asdasdas </text>
</myitem>
And you can use whatever you want in the body of the request. XML, JSON, PHP SERIALIZE or your own data format.
A: If you truly want to be RESTful about this, you'd definitely want to use a POST request to create records. That's if you care to be strict about the standard, but it would also help you because I'm reading that your array's length could vary tremendously - sometimes 1 ID, perhaps 30 other times, etc. URI query strings do (or used to?) have a maximum character limit that you could conceivably bump up against.
If you roll with a POST request, you could easily passing in a comma-delimited list (think about how a field name with multiple checkboxes is passed) or, my favorite mechanism, a JSON-encoded array (represented as a string that can easily be JSON-decoded on the other side.
A: This actually applies to any web page, not just CakePHP.
Any web page which wants to send a large number of fields has to include them all in their POST request.
If you had a web page form with 50 inputs and a submit at the bottom, the page would by default serialise the data and send it in the form request.
If you don't want all the data sent in seperate bars, then using a seperator would work fine too and would mean they all went in 1 parameter.
Somthing like:
http://mysite/items/create?mydata=23-45-65-32-43-54-23-23-656-77
A: another option:
$safedata = base64_encode(serialize($arrayofdata));
and pass it to URL as safe string.
then uncompress it:
$data = unserialize(base64_decode($safedata); | unknown | |
d513 | train | If you know that the list is the value associated to the 'result' key, simply call dct['result'].
>>> dct = {'result': ['activeaddresses', 'exchangevolume(usd)', 'marketcap(usd)', 'mediantxvalue(usd)', 'price(usd)', 'txcount', 'txvolume(usd)']}
>>> dct
{'result': ['activeaddresses', 'exchangevolume(usd)', 'marketcap(usd)', 'mediantxvalue(usd)', 'price(usd)', 'txcount', 'txvolume(usd)']}
>>> dct['result']
['activeaddresses', 'exchangevolume(usd)', 'marketcap(usd)', 'mediantxvalue(usd)', 'price(usd)', 'txcount', 'txvolume(usd)']
Converting the values to a list is unneeded, inefficient and might return the wrong value if your dict has more than 1 (key, value) pair.
A: Your dictionary have only one value and that itself is a list of elements. So just call the result key and you will get the list value.
If you want the list from your code add the index [0] like,
dList = list(dct.values())[0]
Hope this helps! Cheers! | unknown | |

d523 | train | The Entity Framework uses only the information in the attribute to convert the method call to SQL. The implementation is not used in this case.
A: The EdmFunction attribute calls the specified method in SQL. The implementation you have in C# will be ignored. So in your case STR method is called at SQL end.
You can have your method as:
[EdmFunction("SqlServer", "STR")]
public static string ConvertToString(double? number)
{
throw new NotSupportedException("Direct calls not supported");
}
and still it would work.
See: EDM and Store functions exposed in LINQ
How it works
When a method with the EdmFunction attribute is detected within a LINQ
query expression, its treatment is identical to that of a function
within an Entity-SQL query. Overload resolution is performed with
respect to the EDM types (not CLR types) of the function arguments.
Ambiguous overloads, missing functions or lack of overloads result in
an exception. In addition, the return type of the method must be
validated. If the CLR return type does not have an implicit cast to
the appropriate EDM type, the translation will fail.
As a side note, you can also use SqlFunctions.StringConvert like:
var student = (from s in Students
where SqlFunctions.StringConvert((double) s.LanguageId)).Trim() == "2"
select s).FirstOrDefault(); | unknown | |
d524 | train | There are several things here:
*
*You need to define area as being a square length with type area = radius * radius. Otherwise the compiler has no way to match your input and output units.
*Pi, when used like this, is dimensionless, which is represented in F# as <1> or just no unit suffix.
[<Measure>] type radius
[<Measure>] type area = radius * radius
let convertRadiusToArea (r:float<radius>) : float<area> =
let pi = System.Math.PI
r * r * pi
A: A better example of using F#'s unit of measure would be this:
[<Measure>] type cm
let convertRadiusToArea(r:float<cm>) : float<cm^2> =
r * r * System.Math.PI
The idea being that you get benefits of the units of measurement in your calculations and derivations. You're not getting that by creating a unit of measure called 'radius'. Is it in meters? Feet? Centimetres? And that is why you would introduce them into an F# function, to be non-ambiguous about the unit of measurement for the inputs and outputs.
Units of measure in F# should IMO be modelled the way we use units of measurement in any other calculations or real world example like speed, temperature, force etc. | unknown | |

d527 | train | This is not possible in Dart as it stands today.
Parameterized types (things like List<int>) can take literal types (e.g., List<Chicken>) or type parameters (e.g., List<T> where T is declared as a type parameter in a generic, as it in Cage) as arguments. They cannot take arbitrary expressions, even if those are of type Type.
A variable such as t might hold a Type (as in your example) but in general it is really hard to be sure of that. It could just as easily hold a non-type value such as the number 3, because Dart's type system does not guarantee that something with static type Type really is a Type.
If we let these through, the system would be thoroughly corrupted. We could add runtime checks for that, but that would hit performance.
A: This is not (yet) supported.
There was some explanation somewhere, I'll have to look it up.... | unknown | |
d528 | train | As you mentioned you will have an error raised if you have a major dtypes error (for example using int64 when the column is float64). However, you won't have an error if for example you use int8 instead of int16 and the range of your values does not match the range of int8 (i.e -128 to 127)
Here is a quick example:
from io import StringIO
import pandas as pd
s = """col1|col2
150|1.5
10|2.5
3|2.5
4|1.2
8|7.5
"""
pd.read_csv(StringIO(s),sep='|', dtype={"col1": "int8"})
And the output is:
col1 col2
0 -106 1.5
1 10 2.5
2 3 2.5
3 4 1.2
4 8 7.5
So as you can see, the first value in the column col1 has been converted from 150 to -106 without any error / warning from pandas.
The same is applied to float types, I just used int for convenience.
EDIT I add an example with floats since this is what you were asking:
from io import StringIO
import pandas as pd
s = """col1|col2
150|32890
10|2.5
3|2.5
4|1.2
8|7.5
"""
If you read it without specifying the dtype:
pd.read_csv(StringIO(s),sep='|'))
col1 col2
0 150 32890.0
1 10 2.5
2 3 2.5
3 4 1.2
4 8 7.5
If you read it with specifying the "wrong" dtype for the columns:
pd.read_csv(StringIO(s),sep='|', dtype={"col1": "int8", "col2": "float16"})
col1 col2
0 -106 32896.000000
1 10 2.500000
2 3 2.500000
3 4 1.200195
4 8 7.500000
If you have a large CSV file and you want to optimize the dtypes, you can load the CSV file column by column (this should not take too much memory) with no dtype then infer the optimal dtype thanks to the values inside the column and load the full CSV with the optimized dtypes. | unknown | |
d529 | train | $foo is a local (uninitialized) variable inside a function. It is different from the global variable $foo ($GLOBALS['foo']).

Use:
s_name=(String)request.getParameter("s_name");

To get the values before setting them in the session
A: Maybe that is the problem?
String s_name=null, s_password=null, s_location=null;
And then you set session to this null values.
A: You have to first request that parameter before setSession statement;
so in ShopRegister3.jsp, after s_name initialization to `null´.
Request that parameter like:
s_name = request.getParameter("s_name");
Now you can setSession for this variable; it will not return null for s_name variable now. | unknown | |

You will have to write a database function (PL/SQL) that loops through the string and replaces part by part. You will certainly know how to interpret PPP :-)

d534 | train | if((boolean1 && !boolean2) || (boolean2 && !boolean1))
{
//do it
}
IMHO this code could be simplified:
if(boolean1 != boolean2)
{
//do it
}
A: With code clarity in mind, my opinion is that using XOR in boolean checks is not typical usage for the XOR bitwise operator. From my experience, bitwise XOR in Java is typically used to implement a mask flag toggle behavior:
flags = flags ^ MASK;
This article by Vipan Singla explains the usage case more in detail.
If you need to use bitwise XOR as in your example, comment why you use it, since it's likely to require even a bitwise literate audience to stop in their tracks to understand why you are using it.
A: You can simply use != instead.
A: I think you've answered your own question - if you get strange looks from people, it's probably safer to go with the more explicit option.
If you need to comment it, then you're probably better off replacing it with the more verbose version and not making people ask the question in the first place.
A: I find that I have similar conversations a lot. On the one hand, you have a compact, efficient method of achieving your goal. On the other hand, you have something that the rest of your team might not understand, making it hard to maintain in the future.
My general rule is to ask if the technique being used is something that it is reasonable to expect programmers in general to know. In this case, I think that it is reasonable to expect programmers to know how to use boolean operators, so using xor in an if statement is okay.
As an example of something that wouldn't be okay, take the trick of using xor to swap two variables without using a temporary variable. That is a trick that I wouldn't expect everybody to be familiar with, so it wouldn't pass code review.
A: I think it'd be okay if you commented it, e.g. // ^ == XOR.
A: You could always just wrap it in a function to give it a verbose name:
public static boolean XOR(boolean A, boolean B) {
return A ^ B;
}
But, it seems to me that it wouldn't be hard for anyone who didn't know what the ^ operator is for to Google it really quick. It's not going to be hard to remember after the first time. Since you asked for other uses, its common to use the XOR for bit masking.
You can also use XOR to swap the values in two variables without using a third temporary variable.
// Swap the values in A and B
A ^= B;
B ^= A;
A ^= B;
Here's a Stackoverflow question related to XOR swapping.
A: I personally prefer the "boolean1 ^ boolean2" expression due to its succinctness.
If I was in your situation (working in a team), I would strike a compromise by encapsulating the "boolean1 ^ boolean2" logic in a function with a descriptive name such as "isDifferent(boolean1, boolean2)".
For example, instead of using "boolean1 ^ boolean2", you would call "isDifferent(boolean1, boolean2)" like so:
if (isDifferent(boolean1, boolean2))
{
//do it
}
Your "isDifferent(boolean1, boolean2)" function would look like:
private boolean isDifferent(boolean1, boolean2)
{
return boolean1 ^ boolean2;
}
Of course, this solution entails the use of an ostensibly extraneous function call, which in itself is subject to Best Practices scrutiny, but it avoids the verbose (and ugly) expression "(boolean1 && !boolean2) || (boolean2 && !boolean1)"!
A: != is OK to compare two variables. It doesn't work, though, with multiple comparisons.
A: str.contains("!=") ^ str.startsWith("not(")
looks better for me than
str.contains("!=") != str.startsWith("not(")
A: If the usage pattern justifies it, why not? While your team doesn't recognize the operator right away, with time they could. Humans learn new words all the time. Why not in programming?
The only caution I might state is that "^" doesn't have the short circuit semantics of your second boolean check. If you really need the short circuit semantics, then a static util method works too.
public static boolean xor(boolean a, boolean b) {
return (a && !b) || (b && !a);
}
A: As a bitwise operator, xor is much faster than any other means to replace it. So for performance critical and scalable calculations, xor is imperative.
My subjective personal opinion: It is absolutely forbidden, for any purpose, to use equality (== or !=) for booleans. Using it shows lack of basic programming ethics and fundamentals. Anyone who gives you confused looks over ^ should be sent back to the basics of boolean algebra (I was tempted to write "to the rivers of belief" here :) ). | unknown | |

d537 | train | Why not bundle a prebuilt Realm file as part of your application instead? To do this you'll need to:
*
*Create the prebuilt Realm file, either using Realm Browser or a simple Mac app of your own creation.
*Add the prebuilt Realm file to your app target in your Xcode project, ensuring that it appears in the Copy Bundle Resources build phase.
*Add code similar to that found in the above link to your app to have it open the prebuilt Realm file as read-only. Alternatively, you could copy the file out of your app bundle into the user's documents or cache directory and open it read-write. | unknown | |
d538 | train | Yes its quite obvious that you are using old style of joining, still if you need to avoid NULL value to show on data then you can use IFNULL() function for avoiding NULL.
Example :-
select ifnull(members.username,'this is null part') as username from table_name;
This query will print the null part ,if the username is null either it will print the username only.
You can apply to your all column when you are fetching the column data in your query.
Hope it will help you. | unknown | |
d539 | train | Hibernate ORM 5.3 implements the JPA 2.2 standard.
Supported types from the Java 8 Date and Time API
The JPA 2.2 specification says that the following Java 8 types are supported:
*
*java.time.LocalDate
*java.time.LocalTime
*java.time.LocalDateTime
*java.time.OffsetTime
*java.time.OffsetDateTime
Hibernate ORM supports all these types, and even more:
*
*java.time.ZonedDateTime
*java.time.Duration
Entity mapping
Assuming you have the following entity:
@Entity(name = "DateTimeEntity")
public static class DateTimeEntity {
@Id
private Integer id;
@Column(name = "duration_value")
private Duration duration = Duration.of( 20, ChronoUnit.DAYS );
@Column(name = "instant_value")
private Instant instant = Instant.now();
@Column(name = "local_date")
private LocalDate localDate = LocalDate.now();
@Column(name = "local_date_time")
private LocalDateTime localDateTime = LocalDateTime.now();
@Column(name = "local_time")
private LocalTime localTime = LocalTime.now();
@Column(name = "offset_date_time")
private OffsetDateTime offsetDateTime = OffsetDateTime.now();
@Column(name = "offset_time")
private OffsetTime offsetTime = OffsetTime.now();
@Column(name = "zoned_date_time")
private ZonedDateTime zonedDateTime = ZonedDateTime.now();
//Getters and setters omitted for brevity
}
The DateTimeEntity will have an associated database table that looks as follows:
CREATE TABLE DateTimeEntity (
id INTEGER NOT NULL,
duration_value BIGINT,
instant_value TIMESTAMP,
local_date DATE,
local_date_time TIMESTAMP,
local_time TIME,
offset_date_time TIMESTAMP,
offset_time TIME,
zoned_date_time TIMESTAMP,
PRIMARY KEY (id)
)
Source: Mapping Java 8 Date/Time entity attributes with Hibernate
A: Since version 2.2, JPA offers support for mapping Java 8 Date/Time API, like LocalDateTime, LocalTime, LocalDateTimeTime, OffsetDateTime or OffsetTime.
Also, even with JPA 2.1, Hibernate 5.2 supports all Java 8 Date/Time API by default.
In Hibernate 5.1 and 5.0, you have to add the hibernate-java8 Maven dependency.
So, let's assume we have the following Notification entity:
@Entity(name = "Notification")
@Table(name = "notification")
public class Notification {
@Id
private Long id;
@Column(name = "created_on")
private OffsetDateTime createdOn;
@Column(name = "notify_on")
private OffsetTime clockAlarm;
//Getters and setters omitted for brevity
}
Notice that the createdOn attribute is a OffsetDateTime Java object and the clockAlarm is of the OffsetTime type.
When persisting the Notification:
ZoneOffset zoneOffset = ZoneOffset.systemDefault().getRules()
.getOffset(LocalDateTime.now());
Notification notification = new Notification()
.setId(1L)
.setCreatedOn(
LocalDateTime.of(
2020, 5, 1,
12, 30, 0
).atOffset(zoneOffset)
).setClockAlarm(
OffsetTime.of(7, 30, 0, 0, zoneOffset)
);
entityManager.persist(notification);
Hibernate generates the proper SQL INSERT statement:
INSERT INTO notification (
notify_on,
created_on,
id
)
VALUES (
'07:30:00',
'2020-05-01 12:30:00.0',
1
)
When fetching the Notification entity, we can see that the OffsetDateTime and OffsetTime
are properly fetched from the database:
Notification notification = entityManager.find(
Notification.class, 1L
);
assertEquals(
LocalDateTime.of(
2020, 5, 1,
12, 30, 0
).atOffset(zoneOffset),
notification.getCreatedOn()
);
assertEquals(
OffsetTime.of(7, 30, 0, 0, zoneOffset),
notification.getClockAlarm()
); | unknown | |

d542 | train | <br> is outdated. Use the self-closing <br /> instead. The names should be wrapped in something (p, span, h3, something). There are 2 styles (one inline (inside the document) and one attached to #header) that are adding around 500px of space there. That's why there is a large gap.
Consider making it easier on yourself.. use 1 class to define each TYPE of object.
#people {
styles for container div
}
.box {
styles for the individual boxes
}
.photo {
styles for <img>
}
.title {
styles for names of people

price = $('.price', this).val(), // get the new price
total = price*quantity;
$('.total', this).val(total); //set the row total

return tot.val(); // get each row total into an array

d549 | train | To elaborate: destroying a QList will destroy the elements of the list. If the elements are pointers, the pointers themselves are destroyed, not the pointees. You can use qDeleteAll to delete the pointees.
(That will use operator delete, which is the right choice if and only if you're using operator new; malloc will always require free and operator new[] will always require operator delete[]).
That having been said, returning a QList by value won't destroy it, as its refcount won't drop to 0. Getting a crash there means it's very likely that you have some memory corruption. Use valgrind or similar tools to debug that. | unknown | |

d551 | train | I have built several mini-SPA apps using both Knockout.js and Ember.js. There are a lot of good reasons for serving a mini-Single-Page-Application rather than converting your entire app, mainly that client-side code doesn't do everything better.
In my experience, both Angular and Ember.js are very useable without making your whole app client-side. Ember gives you some very useful tools for making "widgets".
For example, if I want my Ember application to render on a part of my server-side page, I can do this:
var App = Ember.Application.create({
// Set the rootElement property to the div that I want my ember app to render inside
rootElement: "#your-root-element",
Resolver: Ember.DefaultResolver.extend({
resolveTemplate: function(parsedName) {
// Override this method to make this app look for its templates in a subdirectory
}
}),
});
// Don't render the app on any page by default
App.deferReadiness();
// Instead, check to see if the #rootElement is present on the page before rendering.
$(document).ready(function() {
if ( $(App.get('rootElement')).length > 0 ) {
App.advanceReadiness();
}
});
I'm sure you can do similarly with Angular.js. I prefer Ember for the following reasons:
*
*A genuine class/mixin system. This is really helpful when you want to share code: it should be very familiar to anyone who is used to working on the server side.
*Very flexible templating.
*Clear separation of concerns, allowing many different views and such to be handled elegantly. | unknown | |
d552 | train | The Jquery plugin hide the original select <select id="combobox"> and apply other HTML tags. So, write CSS for the hidden ones won't change a thing.

d553 | train | You will need a xul browser object to load the content into.
Load the "view-source:" version of your page into a the browser object, in the same way as the "View Page Source" menu does. See function viewSource() in chrome://global/content/viewSource.js. That function can load from cache, or not.
Once the content is loaded, the original source is given by:
var source = browser.contentDocument.getElementById('viewsource').textContent;
Serialize a DOM Document
This method will not get the original source, but may be useful to some readers.
You can serialize the document object to a string. See Serializing DOM trees to strings in the MDC. You may need to use the alternate method of instantiation in your extension.
That article talks about XML documents, but it also works on any HTML DOMDocument.
var serializer = new XMLSerializer();
var source = serializer.serializeToString(document);
This even works in a web page or the firebug console.
A: really looks like there is no way to get "all the sourcecode". You may use
document.documentElement.innerHTML
to get the innerHTML of the top element (usually html). If you have a php error message like
<h3>fatal error</h3>
segfault
<html>
<head>
<title>bla</title>
<script type="text/javascript">
alert(document.documentElement.innerHTML);
</script>
</head>
<body>
</body>
</html>
the innerHTML would be
<head>
<title>bla</title></head><body><h3>fatal error</h3>
segfault
<script type="text/javascript">
alert(document.documentElement.innerHTML);
</script></body>
but the error message would still retain
edit: documentElement is described here:
https://developer.mozilla.org/en/DOM/document.documentElement
A: You can get URL with var URL = document.location.href and navigate to "view-source:"+URL.
Now you can fetch the whole source code (viewsource is the id of the body):
var code = document.getElementById('viewsource').innerHTML;
Problem is that the source code is formatted. So you have to run strip_tags() and htmlspecialchars_decode() to fix it.
For example, line 1 should be the doctype and line 2 should look like:
<<span class="start-tag">HTML</span>>
So after strip_tags() it becomes:
<HTML>
And after htmlspecialchars_decode() we finally get expected result:
<HTML>
The code doesn't pass to DOM parser so you can view invalid HTML too.
A: Maybe you can get it via DOM, using
var source =document.getElementsByTagName("html");
and fetch the source using DOMParser
https://developer.mozilla.org/En/DOMParser

d555 | train | that is that when an image is not found on the server, the instance of a controller is created
Not really. What I believe is happening is that, since you're using a relative path for the image (and calling it directly inside a controller, which is wrong because you're ouputting something before headers), your browser attach the image directly to the CI url, thus making this request to the server:
index.php/doesntexist.png
Which is (correctly) interpreted by CI as a request to a controller, which doesn't exists, and therefore it issues the error class.
You could do, in your actual code (I'd put the images in a view, though):
echo '<img src="/doesntexist.png" />'
using an absoluth path, or using the base_url() method from the url helper:
echo '<img src="'.base_url().'doesntexist.png" />
This should tell the server to fetch the right request (/test/doesntexist.png) and won't trigger that error. | unknown | |

The bootstrap had an error which caused the app to send the request to itself.

d561 | train | You can use xargs with -P option to run any command in parallel:
seq 1 200 | xargs -n1 -P10 curl "http://localhost:5000/example"
This will run curl command 200 times with max 10 jobs in parallel.
A: Using xargs -P option, you can run any command in parallel:
xargs -I % -P 8 curl -X POST --header "http://localhost:5000/example" \
< <(printf '%s\n' {1..400})
This will run give curl command 400 times with max 8 jobs in parallel.
A: Adding to @saeed's answer, I created a generic function that utilises function arguments to fire commands for a total of N times in M jobs at a parallel
function conc(){
cmd=("${@:3}")
seq 1 "$1" | xargs -n1 -P"$2" "${cmd[@]}"
}
$ conc N M cmd
$ conc 10 2 curl --location --request GET 'http://google.com/'
This will fire 10 curl commands at a max parallelism of two each.
Adding this function to the bash_profile.rc makes it easier. Gist
A: Add “wait” at the end, and background them.
for ((request=1;request<=20;request++))
do
for ((x=1;x<=20;x++))
do
time curl -X POST --header "http://localhost:5000/example" &
done
done
wait
They will all output to the same stdout, but you can redirect the result of the time (and stdout and stderr) to a named file:
time curl -X POST --header "http://localhost:5000/example" > output.${x}.${request}.out 2>1 &
A: Wanted to share my example how I utilised parallel xargs with curl.
The pros from using xargs that u can specify how many threads will be used to parallelise curl rather than using curl with "&" that will schedule all let's say 10000 curls simultaneously.
Hope it will be helpful to smdy:
#!/bin/sh
url=/any-url
currentDate=$(date +%Y-%m-%d)
payload='{"field1":"value1", "field2":{},"timestamp":"'$currentDate'"}'
threadCount=10
cat $1 | \
xargs -P $threadCount -I {} curl -sw 'url= %{url_effective}, http_status_code = %{http_code},time_total = %{time_total} seconds \n' -H "Content-Type: application/json" -H "Accept: application/json" -X POST $url --max-time 60 -d $payload
.csv file has 1 value per row that will be inserted in json payload
A: Update 2020:
Curl can now fetch several websites in parallel:
curl --parallel --parallel-immediate --parallel-max 3 --config websites.txt
websites.txt file:
url = "website1.com"
url = "website2.com"
url = "website3.com"
A: This is an addition to @saeed's answer.
I faced an issue where it made unnecessary requests to the following hosts
0.0.0.1, 0.0.0.2 .... 0.0.0.N
The reason was the command xargs was passing arguments to the curl command. In order to prevent the passing of arguments, we can specify which character to replace the argument by using the -I flag.
So we will use it as,
... xargs -I '$' command ...
Now, xargs will replace the argument wherever the $ literal is found. And if it is not found the argument is not passed. So using this the final command will be.
seq 1 200 | xargs -I $ -n1 -P10 curl "http://localhost:5000/example"
Note: If you are using $ in your command try to replace it with some other character that is not being used.
A: Based on the solution provided by @isopropylcyanide and the comment by @Dario Seidl, I find this to be the best response as it handles both curl and httpie.
# conc N M cmd - fire (N) commands at a max parallelism of (M) each
function conc(){
cmd=("${@:3}")
seq 1 "$1" | xargs -I'$XARGI' -P"$2" "${cmd[@]}"
}
For example:
conc 10 3 curl -L -X POST https://httpbin.org/post -H 'Authorization: Basic dXNlcjpwYXNz' -H 'Content-Type: application/json' -d '{"url":"http://google.com/","foo":"bar"}'

d562 | train | I found the answer to my question and record it here for others:
*
*It has been asked before and a first answer can be found here.
*The following information can be found on this MSDN page:
Your application obtains credentials by calling the AcquireCredentialsHandle function, which returns a handle to the requested credentials. Because credentials handles are used to store configuration information, the same handle cannot be used for both client-side and server-side operations. This means that applications that support both client and server connections must obtain a minimum of two credentials handles.
Therefore it can be assumed safe to re-use the same credential handle for multiple connections. And I verified that it indeed makes Schannel re-use the SSL/TLS session. This has been tested on Windows 7 Professional SP1. | unknown | |

d566 | train | This wlil achieve what you want:
contentHeight: contentItem.children[0].childrenRect.height
From Qt docs
Items declared as children of a Flickable are automatically parented to the Flickable's contentItem. This should be taken into account when operating on the children of the Flickable; it is usually the children of contentItem that are relevant.
But I must say it is bad practice for a component to make assumptions about things outside its own QML file, as it makes the component difficult to reuse. Specifically in this case the Flickable is making the assumption that its first child is of a Component type that makes use of the childrenRect property. Your MyFlow component does, but many other components do not, for example an Image. | unknown | |

A: Just as harper89 described, in Mathematica:
FromDigits[ToExpression /@ StringSplit[time, ":"], 60]
A: Try the following:
AbsoluteTime[{"000:03:07.447",
{"Hour", ":", "Minute", ":", "Second", ".", "Millisecond"}}]
(* ==> 187.447 *)
The key was giving an explicit date format (see the docs of DateList[])
This solution works in Mathematica 8. It appears that in version 7 (and possibly also in version 6) one needs to correct the result, like this:
AbsoluteTime[{"000:03:07.447",
{"Hour", ":", "Minute", ":", "Second", ".", "Millisecond"}}] -
AbsoluteTime[{"0", {"Hour"}}] | unknown | |

d573 | train | Why don't you use an npm package for screen recording?
Also your while loop doesn't represent seconds but discrete steps. If you want a time based recording you need some implementation which respects time based steps with step delta to allow adjustment for different rendering speeds. (This is similar to game loops, the only difference is that your action is screen captures and not moving game characters.)
A good screen recording package should do that, as well as providing an API for export. Save your time and effort and use a package for that.

If you want to do something after members, just do it in callback function.

client.smembers("offer", function (err, replies) {
if(!err){
callback(replies);

If you want to do something after a loop,you can try _.after of underscore.js,for example:
var times=10;
var arrayOfReplies=[]; //store all replies
var callback=function(){
//do something with arrayOfReplies
}
var afterAll = _.after(times,callback); //afterAll's callback is a function which will be run after be called 10 times

Every platform has its own design patterns and there is a reason for that.

d582 | train | In MySQL, the DATE type maps to the Java class java.sql.Timestamp. So you should be working with this type to build your query, and not java.util.Date. Here is code which generates the two timestamps you will need:
SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
java.util.Date startDate = formatter.parse(startDate);
java.util.Date endDate = formatter.parse(endDate);
java.sql.Timestamp start = new Timestamp(startDate.getTime());
java.sql.Timestamp end = new Timestamp(endDate.getTime());
Then use your first BETWEEN query to get your result:
PreparedStatement ps = con.prepareStatement("SELECT * FROM project.order
WHERE PO_Date BETWEEN ? AND ?");
ps.setTimestamp(1, start);
ps.setTimestamp(2, end)
Note here that I am using a parametrized PreparedStatement, which avoids (or at least greatly lessens) the possibility of SQL injection.
A: Try this
SELECT * FROM project.order po
WHERE po.PO_Date IS NOT NULL
AND TO_DATE(PO_Date, 'DD/MM/RRRR') >=
TO_DATE('17/02/2015', 'DD/MM/RRRR')

d583 | train | ExecuteReader doesn't actually perform the query. The first call to .Read() will throw the error.
If you want to only catch the SqlException you can do the following:

Console.WriteLine("SQL error.")
Catch ex As Exception
Console.WriteLine("Exception")
Finally
Console.WriteLine("Finally")

exec sp_executesql N'select 1 where N''a'' = @p1',N'@p1 nvarchar(3)',@p1=N'a'
exec sp_executesql N'select 1 where N''1'' = @p1',N'@p1 nvarchar(3)',@p1=N'a'
I totally disagree with Rene Reader.
On my system it executes on ExecuteReader.
ExecuteReader would be a real bad name if it did not actually execute.
Did you consider that it is not catching and exception because it is not throwing an exception.
I know you see an error in SQL Profiler but if I introduce a syntax error it is caught.
This is C# but is is not throwing an exception for me.
And if I change it to:
"select 1 where N'a' = @p1";
Then it returns a row.
If I introduce a syntax error:
"select 1 whereX 1 = @p1";
Then it does throw an exception and it throws it on the ExecuteReader line.
If you want 1 to be a literal you should use:
"select 1 where '1' = @p1";
SQLcmd.CommandType = CommandType.Text;
SQLcmd.CommandText = "select 1 where N'1' = @p1";
SqlParameter TestSqlParameter = new SqlParameter();
TestSqlParameter.ParameterName = "@p1";
TestSqlParameter.SqlDbType = SqlDbType.NChar;
TestSqlParameter.Value = "a";
SQLcmd.Parameters.Add(TestSqlParameter);
try
{
rdr = SQLcmd.ExecuteReader();
Int32 waste;
if (rdr.HasRows)

{
waste = rdr.GetInt32(0);

catch (Exception Ex)

A: I solved this problem if the sql string passed used EXEC sp_executesql by ensuring I read every result and result set... like so:
....
using (var conn = new SqlConnection(_connectionString))
{
try
{
conn.Open();
using (var cmd = new SqlCommand(sql, conn))
{
cmd.CommandTimeout = 0;
using (var rdr = cmd.ExecuteReader())
{
// TODO: Do stuff with the rdr here.
FlushReader(rdr);
}
}
}
catch (Exception ex)
{
_logger.Fatal("Exception: {0}\r\nSQL:\r\n{1}", ex.Message, sql);
throw;
}
finally
{
conn.Close();
}
}
...
/// <summary>
/// Continue trying to read in case the server threw an exception.
/// </summary>
private static void FlushReader(IDataReader rdr)
{
while (rdr.Read())
{
}
while (rdr.NextResult())
{
while (rdr.Read())
{
}
}
}
Without calling the FlushReader method the application continues without throwing an exception of any kind. Even if I use a SQL THROW statement. Running the same sql in SQL management studio will show the error.

d584 | train | MPI covers most of your needs via the MPI Profiling Interface (aka PMPI).
Simply redifines the MPI_* subroutines you need, and have them call the original PMPI_* corresponding subroutine.
In you case:
int MPI_Send(const void *buf, int count, MPI_Datatype datatype, int dest, int tag, MPI_Comm comm)
{
printf(" Calling MPI_Send ************** \n");
PMPI_Send(buf, count, datatype, dest, tag, comm);
}
Since you want to print the line and file of the caller, you might have to use macros and rebuild your app:
#define MPI_Send(buf,count,MPI_Datatype, dest, tag, comm) \
myMPI_Send(buf, count, MPI_Datatype, dest, tag, comm, __func__, __FILE__, __LINE__)
int myMPI_Send(const void *buf, int count, MPI_Datatype datatype, int dest, int tag, MPI_Comm comm, char *func, char *file, int line)

d592 | train | You have two syntax errors in your code:
*
*create function does not support if exists
*character is a reserved SQL keyword.
The below appears to work for me. I'd suggest using an SQL 'ide' such as MySQL workbench. It will show you syntax errors straight away.
DROP function IF EXISTS LeaveNumber;

create function LeaveNumber(str varchar(50)) returns varchar(50)

ulFlags
Type: UINT
Flags that specify the options for the dialog box. This member can be 0 or a combination of the following values. Version numbers refer to the minimum version of Shell32.dll required for SHBrowseForFolder to recognize flags added in later releases. See Shell and Common Controls Versions for more information.
BIF_RETURNONLYFSDIRS (0x00000001)
0x00000001. Only return file system directories. If the user selects folders that are not part of the file system, the OK button is grayed.
Note The OK button remains enabled for "\\server" items, as well as "\\server\share" and directory items. However, if the user selects a "\\server" item, passing the PIDL returned by SHBrowseForFolder to SHGetPathFromIDList fails.
BIF_DONTGOBELOWDOMAIN (0x00000002)
0x00000002. Do not include network folders below the domain level in the dialog box's tree view control.
BIF_STATUSTEXT (0x00000004)
0x00000004. Include a status area in the dialog box. The callback function can set the status text by sending messages to the dialog box. This flag is not supported when BIF_NEWDIALOGSTYLE is specified.
BIF_RETURNFSANCESTORS (0x00000008)
0x00000008. Only return file system ancestors. An ancestor is a subfolder that is beneath the root folder in the namespace hierarchy. If the user selects an ancestor of the root folder that is not part of the file system, the OK button is grayed.
BIF_EDITBOX (0x00000010)
0x00000010. Version 4.71. Include an edit control in the browse dialog box that allows the user to type the name of an item.
BIF_VALIDATE (0x00000020)
0x00000020. Version 4.71. If the user types an invalid name into the edit box, the browse dialog box calls the application's BrowseCallbackProc with the BFFM_VALIDATEFAILED message. This flag is ignored if BIF_EDITBOX is not specified.
BIF_NEWDIALOGSTYLE (0x00000040)
0x00000040. Version 5.0. Use the new user interface. Setting this flag provides the user with a larger dialog box that can be resized. The dialog box has several new capabilities, including: drag-and-drop capability within the dialog box, reordering, shortcut menus, new folders, delete, and other shortcut menu commands.
Note If COM is initialized through CoInitializeEx with the COINIT_MULTITHREADED flag set, SHBrowseForFolder fails if BIF_NEWDIALOGSTYLE is passed.
BIF_BROWSEINCLUDEURLS (0x00000080)
0x00000080. Version 5.0. The browse dialog box can display URLs. The BIF_USENEWUI and BIF_BROWSEINCLUDEFILES flags must also be set. If any of these three flags are not set, the browser dialog box rejects URLs. Even when these flags are set, the browse dialog box displays URLs only if the folder that contains the selected item supports URLs. When the folder's IShellFolder::GetAttributesOf method is called to request the selected item's attributes, the folder must set the SFGAO_FOLDER attribute flag. Otherwise, the browse dialog box will not display the URL.
BIF_USENEWUI
Version 5.0. Use the new user interface, including an edit box. This flag is equivalent to BIF_EDITBOX | BIF_NEWDIALOGSTYLE.
Note If COM is initialized through CoInitializeEx with the COINIT_MULTITHREADED flag set, SHBrowseForFolder fails if BIF_USENEWUI is passed.
BIF_UAHINT (0x00000100)
0x00000100. Version 6.0. When combined with BIF_NEWDIALOGSTYLE, adds a usage hint to the dialog box, in place of the edit box. BIF_EDITBOX overrides this flag.
BIF_NONEWFOLDERBUTTON (0x00000200)
0x00000200. Version 6.0. Do not include the New Folder button in the browse dialog box.
BIF_NOTRANSLATETARGETS (0x00000400)
0x00000400. Version 6.0. When the selected item is a shortcut, return the PIDL of the shortcut itself rather than its target.
BIF_BROWSEFORCOMPUTER (0x00001000)
0x00001000. Only return computers. If the user selects anything other than a computer, the OK button is grayed.
BIF_BROWSEFORPRINTER (0x00002000)
0x00002000. Only allow the selection of printers. If the user selects anything other than a printer, the OK button is grayed.
In Windows XP and later systems, the best practice is to use a Windows XP-style dialog, setting the root of the dialog to the Printers and Faxes folder (CSIDL_PRINTERS).
BIF_BROWSEINCLUDEFILES (0x00004000)
0x00004000. Version 4.71. The browse dialog box displays files as well as folders.
BIF_SHAREABLE (0x00008000)
0x00008000. Version 5.0. The browse dialog box can display sharable resources on remote systems. This is intended for applications that want to expose remote shares on a local system. The BIF_NEWDIALOGSTYLE flag must also be set.
BIF_BROWSEFILEJUNCTIONS (0x00010000)
0x00010000. Windows 7 and later. Allow folder junctions such as a library or a compressed file with a .zip file name extension to be browsed. | unknown | |
d598 | train | I think that the reason of your issue is this line sheet2.getRange(row, 1, 1, 9).copyTo(sheet2.getRange(row, 1, 48, 9), SpreadsheetApp.CopyPasteType.PASTE_VALUES). In this line, the value is copied to 48 rows. But at the next loop, the value is copied to the row of (48 + 1).
In order to remove this issue, how about the following modification?
Pattern 1:
In this modification pattern, the for loop is modified by adjusting the row number.
From:
for (var CR = 1 ; CR < sheet2LastRow; CR++) {
Logger.log(CR); // 1 > 46
sheet2.getRange((CR + 1), 1, 1, 59).moveTo(sheet2.getRange((CR * 49), 1));
// transpose data from rows to columns for Data Studio
sheet2.getRange(1, 12, 1, 48).copyTo(sheet2.getRange((CR * 49), 10), SpreadsheetApp.CopyPasteType.PASTE_VALUES, true); // Dimension
sheet2.getRange((CR * 49), 12, 1, 48).copyTo(sheet2.getRange((CR * 49), 11), SpreadsheetApp.CopyPasteType.PASTE_VALUES, true); // Opportunity
sheet2.getRange((CR * 49), 1, 1, 9).copyTo(sheet2.getRange((CR * 49), 1, 48, 9), SpreadsheetApp.CopyPasteType.PASTE_VALUES); // Respondent Info
}
To:
for (var CR = 1 ; CR < sheet2LastRow; CR++) {
var row = (CR * 49) - (CR - 1);
sheet2.getRange((CR + 1), 1, 1, 59).moveTo(sheet2.getRange(row, 1));
sheet2.getRange(1, 12, 1, 48).copyTo(sheet2.getRange(row, 10), SpreadsheetApp.CopyPasteType.PASTE_VALUES, true);
sheet2.getRange(row, 12, 1, 48).copyTo(sheet2.getRange(row, 11), SpreadsheetApp.CopyPasteType.PASTE_VALUES, true);
sheet2.getRange(row, 1, 1, 9).copyTo(sheet2.getRange(row, 1, 48, 9), SpreadsheetApp.CopyPasteType.PASTE_VALUES);
}
Pattern 2:
In this modification pattern, the for loop is not modified. After all values were copied, the empty rows are deleted.
From:
sheet2.deleteRows(2, 47);
var sheet2NewLastRow = sheet2.getLastRow();
To:
sheet2.deleteRows(2, 47);
var values = sheet2.getRange("A2:DL").getValues();
for (var i = values.length - 1; i >= 0; i--) {
if (values[i].every(e => !e.toString())) sheet2.deleteRow(i + 2);
}
var sheet2NewLastRow = sheet2.getLastRow(); | unknown | |
d599 | train | This should work for you:
notes_service.js
app.factory ('NoteService', function($http) {
return {
getAll: function() {
return $http.get('/notes.json').then(function(response) {
return response.data;
});
}
}
});
navCtrl.js
NotesService.getAll().then(function(res){
$scope.cleanArrayOfNotes = res.data;
});
Or, if you want to return the result rather than the promise, you can:
notes_service.js
app.factory ('NoteService', function($http) {
var notes = [];
var promise = $http.get('/notes.json').then(function(response) {
angular.copy(response.data, notes);
return notes;
});
return {
getAll: function() {
return notes;
},
promise: promise
}
});
navCtrl.js
// get array of notes
scope.cleanArrayOfNotes = NotesService.getAll();
// or use promise
NoteService.promise.then(function(response) {
scope.cleanArrayOfNotes = response.data;
}); | unknown | |
