d12801 | train | let leftAlignedColor
if(element.isrespond == "left"){
leftAlignedColor = '#000'
}else{
leftAlignedColor = null
}
<Grid.Column floated={ element.isrespond ? "right" : "left"}><p style={{color: `${leftAlignedColor}`}}> {result.message}</p></Grid.Column>
its better to use a <span>,<p> inside a column as a good practice.
Hope this is helpful!
A: You should apply a conditional style. This will enable you even pass a specific class name that styles the component.
let myStyle = element.isrespond ? {float:"right",color:"blue"} : {float:"left",color:"red"};
<Grid.Column style={myStyle}> {result.message}</Grid.Column>
A: <Grid.Column floated={ element.isrespond ? "right" : "left"}><p style={{color: element.isrespond ? "blue" : "green",background:element.isrespond ? "yellow" : "cyan"}}> {result.message}</p></Grid.Column>
I think this will work. change the required colors. I added botj for color and background. In the above one. its "green" for left and "blue" for right | unknown | |
d12802 | train | You are using wrong method name for sending email in your controller:

If any of the resources inside the cloudformation stack has retain policy set they won't be deleted.
During deletion, AWS CloudFormation deletes the stack but does not delete the retained resources.

d12805 | train | What about use delete keyword?
delete personList[personId];
A: Since you're already assigning the keys of your object to the personId you can just do:
const Delete = (id: string): void => {
const filteredPersonList: Record<string,PersonInfo> = {}
for(let key in personList){
if(key !== id){
filteredPersonList[key] = personList[key]
}
}
setPersonList(filteredPersonList)
}
A: Based on the context (i.e. updating React state) and your code sample, what you're actually trying to do is create a modified copy of the record without mutating the original.
const deletePerson = (personId: string): void => {
// first create a shallow copy of the old record.
const newList = {...personList};
// now delete the entry from the new record
delete newList[personId];
setPersonList(newList)
}
A: Eslint complains with @ehutchllew answer:
40:7 error for..in loops iterate over the entire prototype chain, which is virtually never what you want. Use Object.{keys,values,entries}, and iterate over the resulting array no-restricted-syntax
40:7 error The body of a for-in should be wrapped in an if statement to filter unwanted properties from the prototype guard-for-in
So using the suggested Object.{keys,values,entries}, it becomes:
const Delete = (id: string): void => {
const filteredPersonList: Record<string, PersonInfo> = {};
Object.keys(personList).forEach((key) => {
if (key !== id) {
filteredPersonList[key] = personList[key];

d12807 | train | You can get the index of sodf==11 and then get the loc value -1 onwards.
Here's how to do it.
import pandas as pd
sodf = pd.Series([9,10,10,9,10,11])
x = sodf[sodf == 11].index[0]
print (sodf.loc[x-1:])
Output will be:
4 10
5 11
If you just want the value of the previous row, then you can also give
print (sodf.loc[x-1])
The output will be just the value as this is a pd.Series with one column:

A: Try something like this:
i = sodf[(sodf == 9)].index
i = i.union(i-1)
i = i[i>=0]

As for the error relating to asserting the UsernameToken assertion, you may want to try putting the UsernameToken assertion inside of a SupportingToken or binding assertion depending on what you want to do with the token. It looks like you just want a username and password to be passed in the message without any other security such as a cryptographic binding of the token to the message or encryption so a supporting token will likely fit your needs.
I also urge you to consider the following additional precautions when using a UsernameToken:
*
*Cryptographically bind the token to the message using a signature.
*Use a nonce and created timestamp and cache the token on the server to prevent replay
*Consider encrypting the token (before signing if you also sign) using XML enc
*Using TLS either in lieu of or in addition to the above suggestions

d12811 | train | Does pvc or pv create folders under the cloudshare?
No. A Kubernetes PersistentVolume is just some storage somewhere, and a PersistentVolumeClaim is a way of referencing a PV (that may not immediately exist). Kubernetes does absolutely no management of any of the content in a persistent volume; it will not create directories on startup, copy content from the image into a volume, or anything else. | unknown | |

d12813 | train | The fundamental issue is that a mutable field can only be modified if the struct itself is mutable. As you noted, we need to use byref in the declaration of Age. We also need to make sure a is mutable and lastly we need to use the & operator when calling the function inside. The & is the way to call a function with a byref parameter.
type [<Struct>] Age = { mutable n : int }
let printInside a = printfn "Inside = %d" a.n
let inside (a : Age byref) =
a.n <- a.n + 1
a.n
let mutable a = {n = 1}
printInside a //a = 1
inside &a
printInside a //a = 2
A: Now that I get the pattern, here is a simple example (just an int instead of a struct record) of how to mutate values passed into a function:
let mutable a = 1
let mutate (a : byref<_>) = a <- a + 1
mutate &a
a //a = 2 | unknown | |

d12817 | train | oops.. someone beat me to it...
When you read files as Dataurl on the clientside: reader.readAsDataUrl(...)
the file is encoded in to a base64 string.. That's why if you save the data directly, it's not in the correct format.
As the previous answer states, you base64_decode your data into the correct format.
A: First, there isn't anything in $_POST["data"] because the index (data) is named by the key in the JSON key : value pair, not the JavaScript var.
Secondly, you should change this:
$Handle = fopen($FileName, 'w');
fwrite($Handle, $data);
print "Data Written";
fclose($Handle);
to this:
file_put_contents($FileName, base64_decode($data)); | unknown | |
d12818 | train | You should try to look for TemplateEngine - it could allow to decrease code count and make it more clear.
What Javascript Template Engines you recommend?
A: You should run your code through a linting engine like JSLint or JSHint and you should familiarize yourself with good practice.
Here's one way (of more than one possible solution) to optimize your code:
function populate(myresults) {
var table = $(document.createElement('table'));
$(myresults).each(function (i) {
var row = $(document.createElement('tr')),
cell = $(document.createElement('td')).text(myresults[i].name);
row.append(cell);
table.append(row);
});
$('#divId').append(table);
}
A: Maybe, creating a new DOM element more correct ?
Like this:
function populate(myresults)
{
var str= $('<table />)';
for(var i in myresults){
str.append($('<td />').text(myresults[i].name).appendTo($('<tr />')));
}
$('#divId').empty().append(str);
}
A: You could do it this way:
function populate(myResults)
{
var tab = $('<table />');
for(var i in myResults){
if (myResults.hasOwnProperty(i)) {
var tr = $('<tr />');
tr.append($('<td /'>, {text: i.name}));
tab.append(tr);
}
}
$('#divId').append(tab);
}
Using a template engine as suggested by the others would be preferable as it's a better, more maintainable approach. | unknown | |
d12819 | train | malloc reservers a particular amount of memory on the heap and gives back a pointer to this memory block (or NULL, if it was not able to allocate the desired memory block). Note, however, that malloc will not initialise the memory block in any way. It will not fill it with 0 or any other value; it will simply keep it's content as is.
So the question is actually "what is the initial content of the heap when a program starts?". And the answer is: it depends on the operating system, which portion of memory it assigns to a program when executed, and the content of this memory block is very likely to be just "something undefined", not even random. This can be some recurring patterns of values, it can be zeros, it can be everything.
When you look into different portions of a program's heap, you will probably see this "something undefined" content, regardless of whether you have used malloc before or not. You may see recurring patterns as in your case. Note, however, that "looking into" portions of the heap that have not been allocated before is actually undefined behaviour. | unknown | |

d12821 | train | Here's your culprit.

This is exactly the reason why you shouldn't use overflow hidden for clearing floats. Anchor links will cause overflowed elements to scroll in certain situations.

d12822 | train | They are completely different things: one declares a class property, and the other is the name of the class constructor.
There is no such thing as "one or the other" here.
I suggest re-reading all about classes and objects in your PHP book, or the manual.
A: public $var is not a constructor, which __construct() is. I hope you meant something else.
As stated in the manual, there's two kinds of constructors:
class Bar {
public function Bar() {
// "old" style constructor
}
}
class Foo {
function __construct() {
// new style constructor
}
}
A: public $var;
Declares a variable that will be accessible to the outside world.
function __construct () { /* Do stuff */ }
Defines the "magic" constructor method. This method will be invoked when a new instance is created (i.e. when you create a new object). This method is what accepts and handles any arguments that are passed when creating a new object.
The key difference is that one defined a variable (property) and one defines a function (method). | unknown | |
d12823 | train | We can use that.
var myBoolean = { value: false }
//get
myBoolean.value;
//set
myBoolean.value = true;
A: Several problems there:
*
*'false' is not false.
*Variables are passed by value in JavaScript. Always. So there is no connection whatsoever between the boolVar in setToFalse and the isOpen you're passing into it. setToFalse(isOpen) is processed like this:
*
*The value of isOpen is determined
*That value (completely disconnected from isOpen) is passed into setToFalse
*JavaScript has some interesting handling around primitive types: If you try to use them like object types (var a = 42; a.toFixed(2); for instance), the value gets promoted to a temporary object, that object is used, and then the object is discarded. So if obj is false, obj.anything = "whatever" ends up being a no-op, because the object that temporarily exists ends up getting released as soon as the line finishes.
You could do something like what you're doing by promoting isOpen to an object via new Boolean, but beware that it will then act like an object, not a boolean:
function modifyVar(obj, val) {
obj.valueOf = obj.toSource = obj.toString = function(){ return val; };
}
function setToFalse(boolVar) {
modifyVar(boolVar, false);
}
var isOpen = new Boolean(true); // An object
setToFalse(isOpen);
snippet.log('isOpen ' + isOpen);
<!-- Script provides the `snippet` object, see http://meta.stackexchange.com/a/242144/134069 -->
<script src="http://tjcrowder.github.io/simple-snippets-console/snippet.js"></script>
That works because the value in isOpen is a reference to an object. So when that value is passed into setToFalse as boolVar, boolVar's value is a copy of that reference, and so refers to the same object. So that sorts out issue #2 above. Issue #3 is solved by creating an object explicitly, rather than relying on the implicit behavior.
But, remember my warning above about how it will act like an object (because it is one), not like a boolean? Here's an example:
function modifyVar(obj, val) {
obj.valueOf = obj.toSource = obj.toString = function(){ return val; };
}
function setToFalse(boolVar) {
modifyVar(boolVar, false);
}
var isOpen = new Boolean(true); // An object
setToFalse(isOpen);
snippet.log('isOpen ' + isOpen);
if (isOpen) {
snippet.log("isOpen is truthy, what the...?!");
} else {
snippet.log("isOpen is falsey");
}
<!-- Script provides the `snippet` object, see http://meta.stackexchange.com/a/242144/134069 -->
<script src="http://tjcrowder.github.io/simple-snippets-console/snippet.js"></script>
We see:
isOpen false
isOpen is truthy, what the...?!
...because isOpen contains a non-null object reference, and non-null object references are always truthy.
A: You are passing boolean primitive variable isObject. For primitive types it doesn't make sense to try to set toString method, because it's not needed (and used), since in ECMAScript spec there are already defined rules for to String conversion.
If you really want to use modifyVar function like you are trying, you can work with Boolean object instead of primitive:
function modifyVar(obj, val) {
obj.valueOf = obj.toSource = obj.toString = function(){ return val; };
}
function setToFalse(boolVar) {
modifyVar(boolVar, 'false');
}
var isOpen = new Boolean(true);
setToFalse(isOpen);
console.log('isOpen ' + isOpen);
So the answer: use new Boolean(true) or Object(true).
A: I am not sure but you are assigning false in single quote, value withing single/double quotes will be considered as string. Just use modifyVar(boolVar, false); and try. | unknown | |
d12824 | train | I think GCC is correct in accepting the given example. This is because the static data member named constant is an ordinary data member variable(although it is still considered a templated entity).
And since constant is an ordinary data member variable, dcl.constexpr#1.sentence-1 is applicable to it:
The constexpr specifier shall be applied only to the definition of a variable or variable template or the declaration of a function or function template.
(emphasis mine)
Thus, as the construct that you have provided after the class template is nothing but an out-of-class definition for the ordinary static data member constant, the given example is well-formed.
template <typename T>
constexpr Test<T> Test<T>::constant {42}; //this is an out-of-class definition for the ordinary static data member variable `constant`
Note
Note that dcl.constexpr#1.sentence-1 doesn't mention templated entity, but instead only mention "variable" and "variable template" and since constant is a variable(ordinary), the same should be applicable to constant. | unknown | |
d12825 | train | Simply call RavenDB to load the object with the appropriate ID, make the changes to its contents and persist it again.
No need to worry about any UpdateModel calls. It doesn't apply here.
Be aware of one potential issue since you are including the id in the model. If I sent a PUT command to http://server/controller/pages-3 with that body what would happen? You should probably send me a bad request response or something similar depending on how you want your API to work.
A: Is there any reason not to be explicit in your parameters? I would define an UpdateModel and take that as parameter instead of the dynamic. Then it also would be able to model validation.
ASP.NET WebApi includes handling of converting from both JSON and XML as input to your controller methods. I'm guessing your combination of custom mediatypeformatter and use of dynamic would be unneccesary in this case, if there is not something I'm missing. | unknown | |
d12826 | train | If I understand you correctly, you want to have 2 "columns" (variables) that contain obstacles but cannot both contain obstacles in the same "row" (bit)
If this is the case the first observation I would make is that any time there is a blockage in the left column the possible options of the right column on both sides of that blockage are totally independent, in fact if my left column looks something like this:
000110000
Then really I just need to find all combinations of obstacles for R=3 and also for R=4 then the final answer will be the Cartesian product of filling those 2 gaps with the combinations.
So first we can write some code to make all possible permutations of obstacles for a given R which we can do recursively, you indicated you wanted to move away from bitwise so I'll use tuple concatenation as it will likely be a little easier to manipulate for your actual task than bit operations.
def obstacle_combos(R):
"""
yields all sequences of obstacles with size 'size'
obstacle_patterns is a set of tuples representing different obstacles
"""
if R==0:
# cannot fit any blocks of size 0
yield ()
return
if R==1:
# this ensures the loop below can always check combo[-1] without index error
yield (0,)
return
for combo in obstacle_combos(R-1):
yield combo + (0,)
if combo[-1] == 0:
# when the last element is empty we could instead put a block of 1s as well.
yield combo[:-1] + (1,1)
print(*obstacle_combos(5), sep="\n")
The way this works is relatively straight forward, the base case of R=0 and R=1 are the trivial case, otherwise we check for R-1 and that combo with an extra 0 at the end is a valid obstacle combo for R, but also if the last element is 0 we can stick a 11 at the end as well so that becomes a conditional extra case.
The next step would be to identify runs of consecutive 0s, this is also not particularly complicated we just iterate over the sequence and implement some logic when we switch from 0 to 1 or 1 to 0 etc:
def find_gaps(obstacle_sequence):
"yields (slice, size) for each range of concecutive 0s in the sequence"
in_seq = False #whether we are currently in a run of 0s
for i,elem in enumerate(obstacle_sequence):
if not in_seq and elem == 0:
in_seq = True
start_idx = i
elif in_seq and elem == 1:
in_seq = False
yield slice(start_idx, i), i-start_idx
# after the loop if the last elements were 0s then yield the final sequence
if in_seq:
yield slice(start_idx, len(obstacle_sequence)), len(obstacle_sequence)-start_idx
One thing here that is slightly unorthodox is that I am creating slice objects directly, this is what happens internally if you do x[a:b] it is the same as x[slice(a,b)], the goal here being that later we can use the values this function produces to do something like:
Y = [0]*len(X) # some sequence of same size as X
for idx_range, size in find_gaps(X):
Y[idx_range] = generate_seq_of_length(size)
to set ranges of Y (which will end up being our right_obstacles eventually) with minimal effort outside the find_gaps function.
Now the tricky part, we want a function to take a left_obstacles sequence of 1s and 0s, find all the runs of 0s by calling find_gaps and at the same time find all the combinations of obstacles we could put in that section. Then go over all combinations (cartesian product) of the obstacles that can be laid out in each region.
import itertools
def place22blocks(left_obstacles):
# start by making a sequence of the same size as left_obstacles
right_obstacles = [0 for _ in left_obstacles]
# then we will find all the gaps and setup the obstacle_combos for each one
gap_ranges = []
seq_filling_iterators = []
for idx_range, size in find_gaps(left_obstacles):
gap_ranges.append(idx_range)
seq_filling_iterators.append(obstacle_combos(size))
# at this point each element of seq_filling_iterators is an iterator
# that will give the different possibilities of obstacles for each region,
# the final result of possible obstacles is the cartesian product of all of them
for list_of_obstacles_per_gap in itertools.product(*seq_filling_iterators):
# list_of_obstacles_per_gap is now a list of the sequences to fill in each gap, it is the "generate_seq_of_length(size)" in the previous example essentially.
for idx_range, seq in zip(gap_ranges, list_of_obstacles_per_gap):
right_obstacles[idx_range] = seq
# since we are reusing the right_obstacles variable every loop we will need to make a copy for each valid obstacle list, will make it a tuple so it is immutable but you could also do list(right_obstacles) if you wanted.
yield tuple(right_obstacles)
print(*place22blocks((0,0,0,1,1,0,0,0)),sep="\n")
This function I will admit is very complicated to fully wrap your head around for how short it is. gap_ranges is the list of ranges where we have space to put obstacles which is parallel to list_of_obstacles_per_gap that is the list of sequences, each element matching with the indices stored in gap_ranges which is why we zip them together. The way list_of_obstacles_per_gap is generated is a little harder to grasp though, the first thing is that product is like a nested loop:
# example loop:
for x in range(5):
for y in ["a","b","c"]:
for z in range(10):
things = (x,y,z)
# that would be equivalent to
for things in itertools.product(range(5), ["a","b","c"], range(10)):
pass
so an example that might help would be to think about how the code would work if there were exactly 2 gaps to put obstacles:
for obs_seq1 in obstacle_combos(3):
for obs_seq2 in obstacle_combos(4):
right_obstacles[0:3] = obs_seq1
right_obstacles[5:9] = obs_seq2
print(right_obstacles)
so in the function above the outer loop is collapsing an arbitrary number of nested loops and the inner loop is performing all those sequence assignments.
No idea if any of this will actually help you, I'm still not sure exactly what you are trying to accomplish but I had fun working through this, happy coding :)
Also note if you wanted to implement this more efficient algorithm with bitwise operations that would be very doable as well:
import itertools
def obstacle_combos(R):
"""
yields all sequences of obstacles with size 'size'
obstacle_patterns is a set of tuples representing different obstacles
"""
if R<=1:
# cannot fit any blocks of size 0
yield 0
return
for c in obstacle_combos(R-1):
# shift the original combo so that we are inserting at the least significant bits,
# is a little simpler than tracking how much to shift the 3 by.
combo = c<<1
yield combo
if combo&3 == 0:
# when the last element is empty we could instead put a block of 1s as well.
yield combo | 3
#print(*obstacle_combos(5), sep="\n")
def find_gaps(obstacle_sequence, R):
"yields (slice, size) for each range of consecutive 0s in the sequence, where slice is the bit position of the least significant bit that is 0"
in_seq = False #whether we are currently in a run of 0s
for i in range(R):
elem = obstacle_sequence & (1<<i)
if not in_seq and elem == 0:
in_seq = True
start_idx = i
elif in_seq and elem > 0:
in_seq = False
yield start_idx, i-start_idx
# after the loop if the last elements were 0s then yield the final sequence

d12827 | train | Let say in your show,have a 'Next' button to trigger the next partial.
In the 'Next' button, I can pass a param[:page1] and all the necessary param when click.
In the 'Show', if there is param[:page1] ,then display _partial1.html.erb
its goes all the same.
A: So if I were you, I would put render all three partials in your show view, and use Javascript, and CSS to manage when each one was shown. If you drop each of those partials in a div, its easy to use JQuery's hide and show methods, linked to the click event of the "Go To Next Step" button. To do it this way you wouldn't have to touch your Controller at all. | unknown | |
d12828 | train | Thanks to Joshua K. Object.keys(o) worked perfectly. | unknown | |
d12829 | train | To get exactly 0 or 1 answers:
dig +short gmail.com mx | sort -n | nawk '{print $2; exit}' | dig +short -f -
You'll need a non-ancient dig that supports +short.
As noted there may be more than one "primary" MX as the preferences need not be unique. If you want all the IP addresses of all of the lowest preference records then:
dig +short oracle.com mx | sort -n |
nawk -v pref=65536 '($1<=pref) {pref=$1; print $2}' |
dig +short -f - | uniq
This does not handle the case where there is no MX record and the A record accepts email, an uncommon but perfectly valid configuration.
Sadly all the dig versions I've tested return 0 whether the domain exists or not (NXDOMAIN), and whether any MX records exist or not. You can catch a DNS time-out (rc=9) though. The related host command does return a non-zero rc with NXDOMAIN, but its behaviour is a little inconsistent, it's messy to script and the output harder to parse.
A poor man's error-checking version (inspired by tripleee's comment) that might be slightly more robust depending on your host command is:
DOMAIN=gmail.com
if ! host -t any $DOMAIN >/dev/null 2>&1 ; then
echo "no such domain"
elif ! host -t mx $DOMAIN >/dev/null 2>&1; then
echo "no MX records"
else
dig +short $DOMAIN mx | sort -n | nawk '{print $2; exit}' | dig +short -f -
fi
(Perversely, you may require an older version of host (bind-8.x) for the -t mx test to work, newer versions just return 0 instead.)
This is just about the point people start backing away nervously asking why you're not using perl/python/$MFTL.
If you really need to write a robust version in bash, check out the djbdns CLI tools and debugging tools which are rather easier to parse (though sadly don't set user exit codes either). | unknown | |
d12830 | train | You can use ng-grid's layout plugin (ng-grid-layout.js). It should come with ngGrid located at:
ng-grid/plugins/ng-grid-layout.js
(UPDATED: now at https://github.com/angular-ui/ng-grid/blob/2.x/plugins/ng-grid-layout.js)
You will have to include an additional script tag pointing to this js file in your main index.html file. And the order of including this versus ng-grid.js is important.
You would have to set a watch on displayEditForm and then call the plugin's updateGridLayout() function.
So it would be something like:
var gridLayoutPlugin = new ngGridLayoutPlugin();
// include this plugin with your grid options
$scope.gridOptions = {
// your options and:
plugins: [gridLayoutPlugin]
};
// make sure grid redraws itself whenever
// the variable that ng-class uses has changed:
$scope.$watch('displayEditForm', function() {
gridLayoutPlugin.updateGridLayout();
});
From my understanding, watches generally belong in the link function rather than the controller but it will work in either spot. You could also go a bit further and say:
$scope.$watch('displayEditForm', function(newVal, oldVal) {
if (newVal !== undefined && newVal !== oldVal) {
gridLayoutPlugin.updateGridLayout();
}
});
To make sure this only fires when the data switches from true/false. This would matter if your data is initially undefined and you waste time calling grid redraw before you give it an initial value. | unknown | |
d12831 | train | I don't think you need require for this.
Why not use the prop you pass and bake that into a string literal that you insert into the component (without require and outside of the return)?
const mobilePath = `./../images/BG/${props.bgmobile}_Mobile.jpg`;
const desktopPath = `./../images/BG/${props.bgdesktop}_Desktop.jpg`;
return(
<Heroes mobile={mobilePath} desktop={desktopPath} />
)
EDIT: the substring part could be added in either <Heroes> before passing the prop. Or by filtering the prop in <Hero> and passing that variable instead of the prop | unknown | |
d12832 | train | I think you must use the javascript closures in order to achive it.
Try it:
var count = element(by.css('li')).count().then(function(c){
return function(){
return c
}
});
var value = count();
Your value should be in the "value" variable.
PS: I don't have a protractor environment to test this code now
A: Here's how I solved it.
function getRow(index) {
var count = $$('li').count();
var test = function(index, count) {
// Ensure a parameter has been passed.
if (index == undefined) {
throw Error("A parameter must be supplied for function getRow. Valid values are 0 through " + count-1);
}
// Ensure the parameter is within bounds
if (index < 0 || index >= count) {
throw Error("The parameter, " + index + ", is not within the bounds of 0 through " + count-1);
}
});
count.then(function(count) {
test(index, count);
}
return $$('li').get(index);
}
I'm not sure why this works and my previous attempt didn't. Well, other than I abstracted the function and allowed myself to pass in the index in a clean manner. | unknown | |
d12833 | train | There are two possible causes of seeing exactly 1e-7 on subtracting 2.0000001-2.0.
One is that many systems round to a reasonable number of digits on output. The exact conversion to decimal of IEEE 64-bit binary 2.0000001-2.0 is 9.9999999836342112757847644388675689697265625E-8. Some systems round to a limited number of significant digits, and might print that as 1e-7. On the other hand, Java, for example, delivers by default enough digits to distinguish the original value from any other double, and prints 9.999999983634211E-8
The other possible cause is if the arithmetic is being done in decimal, in which case the real numbers 2.0000001, 2, and their difference are all exactly representable because they are all decimal fractions. You would need to calculate something like 1/3 to see rounding error. | unknown | |
d12834 | train | How to Create and Use a CollectionView
The following example shows you how to create a collection view and bind it to a ListBox In the same way you can use it with datagrid
<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ListBox ItemsSource={Binding Customers} />
</Window>
public class CustomerView
{
public CustomerView()
{
DataContext = new CustomerViewModel();

public class CustomerViewModel
{
private ICollectionView _customerView;
public ICollectionView Customers
{
get { return _customerView; }
}
public CustomerViewModel()
{
IList<Customer> customers = GetCustomers();
_customerView = CollectionViewSource.GetDefaultView(customers);
}
}
Filtering
To filter a collection view you can define a callback method that determines if the item should be part of the view or not. That method should have the following signature: bool Filter(object item). Now set the delegate of that method to the Filter property of the CollectionView and you're done.
ICollectionView _customerView = CollectionViewSource.GetDefaultView(customers);
_customerView.Filter = CustomerFilter
private bool CustomerFilter(object item)
{
Customer customer = item as Customer;
return customer.Name.Contains( _filterString );
}
Refresh the filter
If you change the filter criteria and you want to refresh the view, you have to call Refresh() on the collection view
public string FilterString
{
get { return _filterString; }
set
{
_filterString = value;
NotifyPropertyChanged("FilterString");
_customerView.Refresh();
}

Whilst it's not in the question your login.ctp template looks something like this:
<?php

That's not how helpers are expected to be used in CakePHP 2.x:
you can use [the helper] in your views by accessing an object named after the
helper:
<!-- make a link using the new helper -->
<?php echo $this->Link->makeEdit('Change this Recipe', '/recipes/edit/5'); ?>

echo $this->Session->flash(); # right
Note also that Session needs to be in the controller $helpers array.
In 1.2 and earlier versions of CakePHP helpers were expected to be variables, this changed but was still supported in 1.3. If your 1.3 CakePHP application has been using helpers in this way, it has been relying on backwards-compatibility with earlier versions. In 2.0 helpers are not variables, and only possible to access as a view class property. Be sure to read the migration guides - for more information on what has changed. | unknown | |

With PHP at view

<?php foreach ( $itemset1 as $item ) { ?>
<li><?php echo $item ?></li>

<header>
<h3>Mylist</h3>
</header>
<ul>
<li ng-repeat="item in itemset1">{{ item }}</li>

d12850 | train | There are both "account" and "Account" types in state package, which seems weird.
There is a meaningful difference between these two names in the language specification.
From the Go Language Specification:
An identifier may be exported to permit access to it from another
package. An identifier is exported if both:
*
*the first character of the identifier's name is a Unicode upper case
letter (Unicode class "Lu"); and
*the identifier is declared in the
package block or it is a field name or method name.
All other identifiers are not exported.
So, taking a closer look at the go-ethereum codebase, here are my observations:
*
*type account in managed_state.go is an internal implementation detail, providing a type for the accounts field in the exported ManageState struct
*type Account in state_object.go is an exported identifier
I think the implementation choice make more sense when you look at the generated documentation.
In particular, the Account type is front and center, detailing a data structure that's of interest to consumers of the package.
When you look at the documentation for the ManageState struct, the unexported fields are purposely not documented. This is because they're internal details that don't impact the exported interface and could easily be changed without impacting users of the package.
In regards to naming recommendations, see the Names section in Effective Go. | unknown | |
d12851 | train | Please use a more recent D compiler. You can download the latest version of the reference D compiler from http://dlang.org/download.html, or you can compile and run a D program online on http://dpaste.dzfl.pl/.
A: It works perfectly fine with a recent compiler. If you're using ideone.com to test this, then that's bound to be your problem. 2.042 is years old now, and it's highly likely that the functionality that you're trying to use was added since then. Looking at the documentation that came with the zip file for 2.042, the documentation for std.format has changed dramatically since then. So, I'd say that the problem is that you're using what is effectively an ancient compiler version. ideone.com hasn't updated their D compiler in years, making them a horrible site to test D code on, especially if it's functionality in the standard library that you're testing out rather than the language itself.
If you want to try compiling D code online, I'd suggest that you try out dpaste. It actually has an up-to-date D compiler, because it's designed specifically for compiling D code examples online. | unknown | |

d12863 | train | I think you are confusing “value type” with “immutable type”. You actually want your ResourceVector to be an immutable type.
An immutable type is one that has no way to change its contents. Once constructed, an instance retains its value until it is garbage-collected. All operations such as addition return a new instance containing the result instead of modifying an existing instance.
string is the most well-known immutable class. All operations like Substring and Replace return a new string and don’t modify the existing strings.
Once your type is properly immutable, semantically it doesn’t matter so much anymore whether it is a value type or a reference type — but it matters to the performance. If you pass values around a lot, you should probably make it a reference type in order to avoid a lot of unnecessary copying. | unknown | |
d12864 | train | [expr.post.incr]/1 ... The value computation of the ++ expression is sequenced before the modification of the operand object. With respect to an indeterminately-sequenced function call, the operation of postfix
++ is a single evaluation. [ Note: Therefore, a function call shall not intervene between the lvalue-to-rvalue conversion and the side effect associated with any single postfix ++ operator. —end note ]...
My reading of this is that the side effects of a++ and b++ must complete before the body of f is executed, and therefore within f it must be that a==1 and b==1. Your examples #2 and #3 are not possible with a conforming implementation.
A call to g is indeterminately sequenced with a call to f, and thus can observe either pre-increment or post-increment values.
A: f(a++, b++) + g();

These are only 2 possibilities not 3.
Either f() will call first and modifies variables a and b

d12866 | train | You should use a form. But how to make it pretty?
With JavaScript you can have a kind of front-end for the form. Hide the form elements and have some JS that changes the form field values on interaction.
Search for pretty forms jquery in Google.
A: From what I understand is that you don't want to manually get the value of each element that has the class 'on'. You could use jQuery's each function looping through all the elements you need. Something like:
var query = "";
$(".on").each(function(i){
if(i === 0) {
query+="?"+$(this).attr('id')+"="+$(this).text();
} else {
query+="&"+$(this).attr('id')+"="+$(this).text();
}
});
(see: http://jsfiddle.net/MkbrV/)
Is this something you are looking for?
A: You could use jQuery's serialize() method:
$('form .on').serialize();

d12867 | train | There is no such event in WinAPI, but you may track it yourself. wParam of all button down/up messages contains information of the state of all buttons at the time of event:
MK_LBUTTON 0x0001 The left mouse button is down.
MK_MBUTTON 0x0010 The middle mouse button is down.
MK_RBUTTON 0x0002 The right mouse button is down.
Thus, you need to keep the track of changes and define a threshold that will filter out all events that you like to consider as a "simultaneous click/release"

A: The class Message has a field "target" which is used to store the handler that you used to send message. When you call a Handler's sendMessage(msg) method, the reference of the handler will be stored in the message. When the Looper dispatch your message it'll call msg.target.dispatchMessage(msg), which means that your msg will be dispatched to the same handler that you used to send it. The method dispatchMessage(msg) will call handleMessage(msg) eventually.

d12873 | train | Usually, PTZ functions are software implemented on the server running in the cam.
Some older cameras used to ship with an activeX control.
These functions can be accessed by getting or posting to a url relative to the camera.
For Your camera, you should be able to post the controls on the following url:
http://<ip>/pantiltcontrol.cgi
Available controls:
POST parameters
PanSingleMoveDegree (default 5)
TiltSingleMoveDegree (default 5)
PanTiltSingleMove
Values for PanTiltSingleMove (based on the web UI controls):
Top 1
Top right 2
Right 5
Bottom right 8
Bottom 7
Bottom left 6
Left 3
Top left 0
Home (reset) 4
So a typical post example using curl to change the pan-tilt, should be similar to this:
curl --user <username>:<password> --user-agent "user" --data "PanSingleMoveDegree=5&TiltSingleMoveDegree=5&PanTiltSingleMove=5" http://<ip>/pantiltcontrol.cgi
For a quick test using your web browser, You should Be able to do the same thing using a get request for the following structured url:
http://<username>:<password>@<ip>/pantiltcontrol.cgi?PanSingleMoveDegree=5&TiltSingleMoveDegree=5&PanTiltSingleMove=5

d12874 | train | You might not have to compile to .class to achieve your goal, you can compile the xsl once per run and re-use the compiled instance for all transformations.
To do so you create a Templates object, like:

xslTemplate = factory.newTemplates(new StreamSource( ... ));
and use the template to get a transformer to do the work:
Transformer transformer = xslTemplate.newTransformer();
Depending on the XSL library you use your mileage may vary.
A: You'll need a Template and a stylesheet cache:

I also added two items into the scripts property array:
"../node_modules/jquery/dist/jquery.min.js",
"../node_modules/jstree/dist/jstree.min.js"
I then updated src/app/app.component.html to
<div id="foo">
<ul>
<li>Root node 1
<ul>
<li>Child node 1</li>
<li><a href="#">Child node 2</a></li>
</ul>
</li>

I also update src/app/app.component.ts to

declare var $: any;
@Component({
selector: 'app-root',

d12876 | train | Assuming you meant the Spirit version ("as a one liner"), below is an adapted version that adds the check for number of elements.
Should you want more control (and on the fly input checking, instead of 'in hindsight') then I recommend you look at another answer I wrote that shows three approaches to do this:
*
*Boost::Spirit::QI parser: index of parsed element
.
#include <boost/spirit/include/qi.hpp>
#include <boost/spirit/include/support_istream_iterator.hpp>
#include <boost/spirit/include/karma.hpp>
namespace spirit = boost::spirit;
namespace qi = boost::spirit::qi;
namespace karma = boost::spirit::karma;
int main()
{
std::cin.unsetf(std::ios::skipws);
spirit::istream_iterator b(std::cin), e;
std::vector<std::vector<int> > vectors;
if (qi::phrase_parse(b, e, +qi::int_ % qi::eol >> qi::eoi, qi::blank, vectors))
{
std::cerr << "Parse failed at '" << std::string(b,e) << "'\n";
return 255;
}
// check all rows have equal amount of elements:
const auto number_of_elements = vectors.front().size();
for (auto& v : vectors)
if (v.size() != number_of_elements)
std::cerr << "Unexpected number of elements: " << v.size() << " (expected: " << number_of_elements << ")\n";
// print the data for verification
std::cout
<< karma::format(karma::right_align(8)[karma::auto_] % ',' % '\n', vectors)
<< std::endl;
return 0;
}
The karma bits are not necessary (they're just there to output the whole thing for demonstration).
UPDATE
To build in more active error checking, you could do:
int num_elements = 0;
bool ok = qi::phrase_parse(b, e,
(+qi::int_) [ phx::ref(num_elements) = phx::size(qi::_1) ]
>> *(qi::eol >> qi::repeat(phx::ref(num_elements)) [ qi::int_ ])
>> *qi::eol,
qi::blank, vectors);
Which uses qi::repeat to expect the num_elements number of elements on subsequent lines. You can just store that into a 1-dimensional array:
#include <boost/spirit/include/qi.hpp>
#include <boost/spirit/include/phoenix.hpp>
#include <boost/spirit/include/support_istream_iterator.hpp>
#include <boost/spirit/include/karma.hpp>

namespace phx = boost::phoenix;
namespace karma = boost::spirit::karma;

{
std::cin.unsetf(std::ios::skipws);
boost::spirit::istream_iterator b(std::cin), e;
//std::vector<std::vector<int> > vectors;
std::vector<int> vectors;
int num_elements = 0;
bool ok = qi::phrase_parse(b, e,
(+qi::int_) [ phx::ref(num_elements) = phx::size(qi::_1) ]
>> *(qi::eol >> qi::repeat(phx::ref(num_elements)) [ qi::int_ ])
>> *qi::eol,
qi::blank, vectors);
std::cout << "Detected num_elements: " << num_elements << "\n";
if (!ok)
{
std::cerr << "Parse failed at '" << std::string(b,e) << "'\n";
return 255;
}
if (b!=e)
std::cout << "Trailing unparsed: '" << std::string(b,e) << "'\n";
// print the data for verification
std::cout
<< karma::format_delimited(karma::columns(num_elements)[+karma::int_], ' ', vectors)
<< std::endl;
return 0;

d12879 | train | Just use the JsonConvert.DeserializeType overload that accepts a type parameter instead of the generic one:
public object GetData(Type t,Uri uri, HttpStatusCode expectedStatusCode)
{
....
return JsonConvert.DeserializeObject(responseString,t);
}
This is a case of the XY problem. You want to deserialize arbitrary types (problem X) and think that somehow, you need pass a generic type at runtime (problem Y), so when you get stuck ,you ask about Y. | unknown | |
d12880 | train | I recommend keeping sequence mode off, like you did for the two pages, and lay out the entire sequence (in pairs) that way. You should then create your own next/previous buttons and use viewer.viewport.fitBounds to animate the viewer to each pair as needed.
Here's an example of a system that does something like that (plus a lot more):
https://iangilman.com/osd/test/demo/m2/
Press the "book" button at the top to see the "two-page" mode. The code for this is here:
https://github.com/openseadragon/openseadragon/tree/master/test/demo/m2
Of course you don't need all of that code, but hopefully it can be a helpful reference. | unknown | |
d12881 | train | At least these problems:
Code is assigning = when it should compare ==.
// if (randOne = 1)
if (randOne == 1)
The last if () { ... } else { ... } will cause one of the 2 blocks to execute. OP wants an if () { ... } else if () { ... } else { ... } tree.
// Problem code
if (randOne = 3) {
randOne = *(symbols+2);
} else {
randOne = *(symbols+3);
}
Suggest
if (randOne == 1) {
randOne = *symbols;
} else if (randOne == 2) {
randOne = *(symbols+1);
} else if (randOne == 3) {
randOne = *(symbols+2);
} else {
randOne = *(symbols+3);
}
Also research switch.
switch (randOne) {
case 1:
randOne = *symbols;
break;
case 2:
randOne = *(symbols+1);
break;
case 3:
randOne = *(symbols+2);
break;
default:
randOne = *(symbols+3);
break;
}
Or consider a coded solution:
randOne = *(symbols+(randOne-1));
But code needs to return a pointer to a string not an int and has no need to pass in randOne as a parameter.
const char * slotOne(const char *symbols[]) {
int randOne = rand() % 4;
return symbols[randOne];
}
Calling code also needs to adjust to receive a const char *, not an int.
// int one;
// one = slotOne(x);
const char *one = slotOne(symbols); | unknown | |
d12882 | train | You didn't specify the version of actionscript in use, so I'll assume you're using as3.
You could
*
*use cue points embedded in the flv (added when creating the flv)
*if you're using the FLVPlayer component, use cue points created with actionscript
*use a regular Timer
If you don't have access to the creating-the-flv-part, the simplest (and the most inaccurate, but I would assume that displaying a button doesn't need to be millisecond-level-accurate) solution would be number three. If the user has no control over the playback (i.e. pause, rewind) and the video isn't being streamed over network, just start/stop a timer with the playback. If the user can pause and rewind the video, you'll have to also stop and adjust the timer every time the user does so. If the video is being streamed over network, you'll have to take any buffering pauses into account, too.
A: You can add cuepoint and listen for them with:
_Player.AddEventListener(MetadataEvent.CUE_POINT, PlayerCuePoint);
function PlayerCuePoint(e:MetadataEvent):void
{
_Button.visible = true;
}
Or you could check the progress like this:
const BUTTON_TIME:Number = 10; //Time in seconds
_Player.AddEventListener(VideoEvent.PLAYHEAD_UPDATE, PlayerPlayheadUpdate);
function PlayerPlayheadUpdate(e:VideoEvent):void
{
if(_Player.playheadTime >= BUTTON_TIME)
_Button.visible = true;

d12883 | train | fundamentally, you're setting yourself up for some race conditions (what if the folder already existed, &c). A better way to do this is creating a fresh folder before you run this script, then run it inside there. So:
dir="$(mktemp aws-sync-XXXXX)"
pushd "$dir"
# do stuff
popd
rm -rf "$dir"
That will ensure you delete everything your temporary command created, and nothing more. | unknown | |

d12887 | train | Define a function that first check if the column exists in the dataframe. If the column does not exist, simply add it. In the case it already exists then use coalesce as before.

d12889 | train | The name of a property's backing field is a compiler implementation detail and can always change in the future, even if you figure out the pattern.
I think you've already hit on the answer to your question: ignore all properties.
Remember that a property is just one or two functions in disguise. A property will only have a compiler generated backing field when specifically requested by the source code. For example, in C#:
public string Foo { get; set; }
But the creator of a class need not use compiler generated properties like this. For example, a property might get a constant value, multiple properties might get/set different portions of a bit field, and so on. In these cases, you wouldn't expect to see a single backing field for each property. It's fine to ignore these properties. Your code won't miss any actual data.
A: You can ignore all properties completely. If a property doesn't have a backing field, then it simply doesn't consume any memory.
Also, unless you're willing to (try to) parse CIL, you won't be able to get such mapping. Consider this code:
private DateTime today;
public DateTime CurrentDay
{
get { return today; }
}
How do you expect to figure out that there is some relation between the today field and the CurrentDay property?
EDIT: Regarding your more recent questions:
If you have property that contains code like return 2.6;, then the value is not held anywhere, that constant is embedded directly in the code.
Regarding string: string is handled by CLR in a special way. If you try to decompile its indexer, you'll notice that it's implemented by the CLR. For these few special types (string, array, int, …), you can't find their size by looking at their fields. For all other types, you can.
A: To answer your other question:Under what circumstances do properties not have backing fields?
public DateTime CurrentDay
{
get { return DateTime.Now; }
}
or property may use any other number of backing fields/classes
public string FullName
{
get {return firstName + " " + lastName;}

d12891 | train | After a quick look, Keith-wood countdown works as follows (example code they provide that works with your code):
newYear = new Date();
var newYear = new Date(newYear.getFullYear() + 1, 1 - 1, 1);
$('#defaultCountdown').countdown({until: newYear});
If I understand your question right, then you simply need to change the code at line 2:
newYear = new Date(newYear.getFullYear() + 1, 1 - 1, 1);
Since this sets the newYear variable to the date you want to count down to. So to set the date as per your question you simply need to properly set the JS constructor for the new Date on that line:
new Date(year, month, day, hours, minutes, seconds, milliseconds)
Hence if you are counting down to a launch at 10AM on the 15th December 2014 then you will just set it to:
new Date(2014, 12, 15, 10, 0, 0, 0)
If you want to know more about the basic set-up, not just changing the dates you can find that here on keith-wood's website.
Hope that helps! | unknown | |

You do not put any port numbers or path parts in it. This will obviously only work if you edit the hosts file on all the computers
you are indending to access the site from and not necessarily on the host running the application itself.

d12896 | train | An array is a contiguous bit of memory, calling a function like this:
foo( ref bAarr[0], bArr.Length );
It passes two things:
*
*The address of the 1st element of the array, and
*The number of elements in the array
Your 3rd-party library is almost certainly a C/C++ DLL exposing a function signature along the lines of
int foo( unsigned char *p, int len );
An array reference like arr[n] is [roughly] the equivalent of the following pseudocode:
*
*let p be the address of arr
*let offset be n multiplied by the size in octets of the array's underlying type
*let pElement be p + offset, the address of element n of array arr.
pElement, when dereferenced, gives you the value of arr[n].
A: @Nicholas explained how it happens but if you want to do the same thing in the c# check the bellow code:
I don't recommend using it, just for satisfying curiosity:
void Main()
{
byte[] bArr = new byte[100];
// fill the entire array without passing it to method
FillEntireArray(ref bArr[0], bArr.Length);
// read the entire array without passing it to method
ReadEntireArray(ref bArr[0], bArr.Length);
}
public unsafe void FillEntireArray(ref byte pByte, int length)
{
fixed (byte* ptr = &pByte)
{
byte* p = ptr;
for (int i = 0; i < length; i++)
{
// set a new value to pointer
*p = ((byte)(i));
// move pointer to next item
p++;
}
}
}
public unsafe void ReadEntireArray(ref byte pByte, int length)
{
fixed (byte* ptr = &pByte)
{
byte* p = ptr;
for (int i = 0; i < length; i++)
{
// Print the value of *p:
Console.WriteLine($"Value at address 0x{(int)p:X} is {p->ToString()}");
// move pointer to next item
p++;
}
}
}
A: shorter form:
public unsafe void FillArray(ref byte arr, int length)
{
fixed (byte* ptr = &arr)
{
for (byte i = 0; i<length; i++)
{
*(ptr + i) = i;
}

d12900 | train | Some sample data would be helpful to help design the queries.
In principal you would need to join the tables together to get the desired result.
You would join the productID on tblOrders to the ProductID on tblProducts. This will net you the name of the product etc.
This would be an INNER join, as every order has a product.
You would then join to tblSpareParts, also using the productID so that you could return the status of the spare parts for that product. This might be a LEFT JOIN instead of an INNER, but it depends on if you maintain a value of 0 for spare parts (e.g. Every product has a corresponding spare parts record), or if you only maintain a spare parts record for items which have spare parts. | unknown |
