d15701 | val | I haven't read all the details of the forum post you're referring to, but i'm sure you need to know a few things about data binding before you can start using it.
*
*The target of a data binding is a dependency
property
*A dependency property has to be declared in a class that is derived from DependencyObject (at least when it is not an attached property, but we don't talk about those here)
*The SetBinding method you're looking for is either a static method in BindingOperations, or a method of FrameworkElement.
So when you're going to set up a binding on some property of your DataRange class, it would have to be derived from DependencyObject, and you would set the binding like this:
DataRange dataRange = ...
Binding binding = ...
BindingOperations.SetBinding(dataRange, DataRange.StartProperty, binding);
If DataRange were derived from FrameworkElement, you could write this:
dataRange.SetBinding(DataRange.StartProperty, binding);
Here DataRange.StartProperty is of type DependencyProperty and represents the Start dependency property of class DataRange.
You should at least read the MSDN articles Data Binding Overview, Dependency Properties Overview and Custom Dependency Properties. | unknown | |
d15702 | val | date in PHP accepts 2 parameters. The first is the format you want the date to be displayed in, and the second is a unix timestamp. What you would be better of using is the DateTime class. Then you can get the timezone like this:
echo (new \DateTime('2019-01-17T10:00:00-05:00'))->format('P'); | unknown | |
d15703 | val | If you already created the mask, you may be able to simplify the rest of it into one command like this...
convert in.png in2.png in3.png null: ^
-matte mask.png -compose dstin -layers composite +append result.png
That would read in the three input images and do the mask composite on each of them all at the same time. Then it appends the three results into a single file for the output.
A: This will do what you ask in Imagemagick using parenthesis processing
Unix syntax:
convert \
\( in.png -matte mask.png -compose DstIn -composite \) \
\( in2.png -matte mask.png -compose DstIn -composite \) \
\( in1.png -matte mask.png -compose DstIn -composite \) \
-append result.png
Windows syntax:
convert ^
( in.png -matte mask.png -compose DstIn -composite ) ^
( in2.png -matte mask.png -compose DstIn -composite ) ^
( in1.png -matte mask.png -compose DstIn -composite ) ^
-append result.png
I note that you have in1.png in the third convert. Did you mean in3.png?
Please always identify your Imagemagick version and platform/OS, since syntax differs.
A: This may be of interest for those wanting to make rounded corners with Imagemagick. Unix syntax.

d15707 | val | you can define a system varible when starting tomcat. and access it from your library.
for example inside your catalina.bat(on windows)/setenv.sh(linux)
windows
set JAVA_OPTS=%JAVA_OPTS% -Dconfig.path=%CATALINA_HOME%/{path to conf file}

d15708 | val | I think what you're actually looking for is:
@Html.ValidationSummary()
A: I would go with @Html.ValidationSummary() if possible
A: Check out Custom ValidationSummary template Asp.net MVC 3. I think it would be best for your situation if you had complete control over how the validation is rendered. You could easily write an extension method for ValidationMessageFor.
A: Actually, at the top should be:
@Html.ValidationSummary(/*...*/)
The field validations should be with their respective fields.
However, if you absolutely insist on putting @Html.ValidationMessageFor(/*...*/) at the top then adjust their layout behavior in your CSS and forget about the <br />'s
A: I'm not sure if there's a built in way, but you could easily make another Extension method:
public static MvcHtmlString ValidationMessageLineFor<TModel, TProperty>(this HtmlHelper<TModel> helper, Expression<Func<TModel, TProperty>> expression) {
return helper.ValidationMessageFor(expression) + "<br />";
}
Something like that? | unknown | |
d15709 | val | You need minor tweaking in your code:
change:
bottom: TabBar(
tabs: _tabs,

body: TabBarView(
children: _tabBarView,

to
bottom: TabBar(
tabs: _tabs.toList(), // Creates a [List] containing the elements of this [Iterable].
),

body: TabBarView(
children: _tabBarView.toList(), // Creates a [List] containing the elements of this [Iterable].

d15710 | val | See this example:
var query = from p in Pets select p;
if (OwnerID != null) query = query.Where(x => x.OwnerID == OwnerID);
if (AnotherID != null) query = query.Where(x => x.AnotherID == AnotherID);
if (TypeID != null) query = query.Where(x => x.TypeID == TypeID);
Hope this help you | unknown | |
d15711 | val | You can't; not with this data structure. You have a few options:
*
*iterate through everything, but abort this iteration at the top if it doesn't match your required state. For example:
for (Card card : deck) {
if (card.getRank() != Rank.ACE) continue;
/* code to deal with aces here */
}
*You use stream API constructs to filter. You did not include your Deck class in your paste, but assuming deck.deck is some sort of java.util.List, you can for example do:
deck.deck.stream().filter(x -> x.getRank() == Rank.ACE).iterator()
which will give you an iterator that iterates through only the aces.
A:
I just want to iterate through all the Spades or all the Kings.
Here we are.
new DeckIterator(deck, card -> Rank.KING.equals(card.getRank()));
new DeckIterator(deck, card -> Suit.SPADES.equals(card.getSuit()));
I fully agree with @rzwitserloot's answer, and will extend his post with my iterator which takes a Predicate to form another iterator that runs over only selected elements.
class DeckIterator implements Iterator<Card> {
private final Iterator<? extends Card> iterator;
public DeckIterator(Deck deck, Predicate<Card> predicate) {
iterator = deck.deck.stream().filter(predicate).iterator();
}
@Override
public boolean hasNext() {
return iterator.hasNext();
}
@Override
public Card next() {
return iterator.next();
}
@Override
public void remove() {
iterator.remove();
}

d15712 | val | I got the same crash log.And my reason is the view controller is released but the UITextField.delegate is not setting nil. So you can set UITextField.delegate = nil in dealloc of the view controller. | unknown | |
d15713 | val | I managed to solve the issue myself. I still cannot fully explain cause and effect here, but this is what I did:
I removed crossorigin="anonymous" from the html's img element. This will at least make sure that the image is always loaded.
The color calculation part I solved by basically rewriting its logic:
var imgSrc = $('#<?= $bigimage['image_id'] ?>').attr('src');
var cacheBurstPrefix = imgSrc.indexOf("?") > -1 ? '&' : '?';
imgSrc += cacheBurstPrefix + 'ts=' + new Date().getTime();
var imagePreloader = new Image();
imagePreloader.crossOrigin = "Anonymous";
imagePreloader.src = imgSrc;
$(imagePreloader).imagesLoaded(function() {
var rgb = getAverageRGB(imagePreloader);
document.body.style.backgroundColor = 'rgb('+rgb.r+','+rgb.g+','+rgb.b+')';
if (rgb!==false) {
$.get(basepath + "image/<?= $bigimage['image_id'] ?>/setcolor/" + rgb.r + "-" + rgb.g + "-" + rgb.b);
}
});
Instead of reusing the img element from the html, I'm creating a new in-memory image element. Using a cache bursting technique I'm making sure it is freshly loaded. Next, I'm using imagesLoaded (a 3rd party plugin) to detect the event of this in-memory image being loaded, which is far more reliable than jQuery's load() event.
I've tested extensively and can confirm that in no case does normal image loading ever break again. It works in every browser and proxy situation. As an added bonus, the color calculation part now seems to work in far more browsers, including several mobile browsers.
Although I am still not confident on the root cause, after much frustration I'm very happy with the new situation. | unknown | |
d15714 | val | Try this,
firstSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
string selectedValue = arg0.getSelectedItem().toString();
if(selectedValue.equalsIgnoreCase(string1)
{
ArrayAdapter<String> firstAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, firstArray);
secondSpinner.setAdapter(firstAdapter);//
}
else if(selectedValue.equalsIgnoreCase(string2)
{
ArrayAdapter<String> firstAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, array2);
secondSpinner.setAdapter(firstAdapter);
}
}
Hope it will help you.
A: If it's a String array you could define it in XML then use getResource().getStringArray() or declare it in Java.
In your listener for the first spinner, you could do the following to set the choices for the second spinner.
secondSpinnerAdapter = new ArrayAdapter<CharSequence>(this, android.R.layout.simple_spinner_item, newArray);
secondSpinner.setAdapter(secondSpinnerAdapter);
Tested and working
A: update the array list of second spinner in 1st spinner setOnItemSelectedListener
spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
string str=spinner1.getSelectedItem().toString();
if(str.equals("spinner item"))//spinner item is selected item of spinner1
{
ArrayAdapter<String>adapter1 = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, array1);
//adapter1.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
spinner2.setAdapter(adapter1);//
}else if{
ArrayAdapter<String>adapter1 = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, array2);

d15716 | val | float((m_df.ix[:,1:1]).values)
For pandas dataframes, type casting works when done on the values, rather than the dataframe. | unknown | |
d15717 | val | You just setState in constructor. If you want to make a call you can put it in componentWillMount() or componentDidMount()
import React, { Component } from 'react';
import './App.css';
//Libraries
import axios from 'axios';
//Components
import SearchBar from './Components/search-bar';
class App extends Component {
constructor(props){
super(props);
this.state = {
city: 'London',
country: 'uk',
temperature: 0,
humidity: 0,
pressure: 0
}
}
citySearch(city){
this.setState({city})
}
componentWillMount(){
//Axios call
let city = this.state.city;
let country = this.state.country;
axios
.get(`http://api.openweathermap.org/data/2.5/weather?APPID=${API_KEY}&q=${city},${country}`)
.then(function(response) {
this.setState({
city: response.data.name,
country: response.data.name,
temperature: response.data.main.temp,
humidity: response.data.main.humidity,
pressure: response.data.main.pressure
});
}.bind(this))
.catch(function(error) {
console.log(error);
});
this.citySearch('London');
}
render() {
return (
<div className="container">
<h1 className="display-1 text-center">Weather App</h1>
<SearchBar onSearchTermChange={citySearch} />
</div>
);
}
}
export default App;
A:
setState(...): Can only update a mounted or mounting component. This
usually means you called setState() on an unmounted component. This is
a no-op. Please check the code for the App component.
This is because of your axios call inside the constructor. Put your axios call in componentDidMount should resolve it
citySearch is not defined
It is because React cannot find citySearch function. You should change
<SearchBar onSearchTermChange={citySearch} />
to
<SearchBar onSearchTermChange={this.citySearch} />
In order to use citySearch this way, you should also bind citySearch in your constructor
In summary:
import React, { Component } from 'react';
import './App.css';
//Libraries
import axios from 'axios';
//Components
import SearchBar from './Components/search-bar';
class App extends Component {
constructor(props){
super(props);
this.state = {
city: 'London',
country: 'uk',
temperature: 0,
humidity: 0,
pressure: 0
}
this.citySearch = this.citySearch.bind(this)
}
componentDidMount() {
//Axios call
let city = this.state.city;
let country = this.state.country;
axios
.get(`http://api.openweathermap.org/data/2.5/weather?APPID=${API_KEY}&q=${city},${country}`)
.then(function(response) {
this.setState({
city: response.data.name,
country: response.data.name,
temperature: response.data.main.temp,
humidity: response.data.main.humidity,
pressure: response.data.main.pressure
});
}.bind(this))
.catch(function(error) {
console.log(error);
});
}
citySearch(city){
this.setState({city})
}
render() {
return (
<div className="container">
<h1 className="display-1 text-center">Weather App</h1>
<SearchBar onSearchTermChange={this.citySearch} />
</div>
);
}
}
export default App;
Don't call setState in your constructor, you can just initialize your state like your did. So the original setState in your constructor should be deleted.
UPDATE
To search again everytime you call citySearch.
import React, { Component } from 'react';
import './App.css';
//Libraries
import axios from 'axios';
//Components
import SearchBar from './Components/search-bar';
class App extends Component {
constructor(props){
super(props);
this.state = {
city: 'London',
country: 'uk',
temperature: 0,
humidity: 0,
pressure: 0
}
this.citySearch = this.citySearch.bind(this)
}
componentDidMount() {
axioSearch();
}
axioSearch(city) {
let city = city || this.state.city;
let country = this.state.country;
axios
.get(`http://api.openweathermap.org/data/2.5/weather?APPID=${API_KEY}&q=${city},${country}`)
.then(function(response) {
this.setState({
city: response.data.name,
country: response.data.name,
temperature: response.data.main.temp,
humidity: response.data.main.humidity,
pressure: response.data.main.pressure
});
}.bind(this))
.catch(function(error) {
console.log(error);
});
}
citySearch(city){
this.axioSearch(city);
}
render() {
return (
<div className="container">
<h1 className="display-1 text-center">Weather App</h1>
<SearchBar onSearchTermChange={this.citySearch} />
</div>
);
}
}
export default App;
A: First, you should not make your axios calls in the constructor. The component is not yet mounted at this point. Do this in a componentDidMount to ensure that the component is already mounted.
Secodly, you did not bind citySearch to the App class. So in the SearchBar component, it does not know that the citySearch Method should be called from the App class. It is advisable to do this binding in the App class constructor for optimization reasons.
Lastly, I will advise you to write React in a more functional way leveraging state management frameworks like Redux or Flux
The code below should work
import React, { Component } from 'react';
import './App.css';
//Libraries
import axios from 'axios';
//Components
import SearchBar from './Components/search-bar';
class App extends Component {
constructor(props){
super(props);
this.state = {
city: 'London',
country: 'uk',
temperature: 0,
humidity: 0,
pressure: 0
}
this.citySearch = this.citySearch.bind(this);
this.citySearch('London');
}
citySearch(city){
this.setState({city})
}
componentDidMount() {
//Axios call
let {city, country} = this.state;
axios
.get(`http://api.openweathermap.org/data/2.5/weather?APPID=${API_KEY}&q=${city},${country}`)
.then(function(response) {
this.setState({
city: response.data.name,
country: response.data.name,
temperature: response.data.main.temp,
humidity: response.data.main.humidity,
pressure: response.data.main.pressure
});
}.bind(this))
.catch(function(error) {
console.log(error);
});
}
render() {
return (
<div className="container">
<h1 className="display-1 text-center">Weather App</h1>
<SearchBar onSearchTermChange={citySearch} />
</div>
);
}
}
export default App;
For the searchBar component, you didn't bind onHandleChange in the SearchBar component. This will throw errors. You should do this in the searchBar constructor
constructor() {
...
this.onHandleChange = this.onHandleChange.bind(this) //Very important you do this
}
A: To pass data from child components to the parent component you have to use a callback method.
Check this out. (About how to pass data from parent to child and child to parent).
I know that I'm not touching your code here (I'm sorry), but if you're interested in a different approach this works.

d15718 | val | Try this
var duplicates = list.GroupBy(a => a).SelectMany(ab => ab.Skip(1).Take(1)).ToList();
A: A simple approach is using Enumerable.GroupBy:
var dups = list.GroupBy(s => s)
.Where(g => g.Count() > 1)
.Select(g => g.Key);
A: List<string> list = new List<string>() { "a", "a", "b", "b", "r", "t" };
var dups = list.GroupBy(x => x)
.Where(x => x.Count() > 1)
.Select(x => x.Key)
.ToList();
A: var list = new List<string> { "a", "a", "b", "b", "r", "t" };
var distinct = new HashSet<string>();
var duplicates = new HashSet<string>();
foreach (var s in list)
if (!distinct.Add(s))
duplicates.Add(s);
// distinct == { "a", "b", "r", "t" }
// duplicates == { "a", "b" }
A: var duplicates = list.GroupBy(s => s).SelectMany(g => g.Skip(1).Take(1)).ToList();
A: var duplicates = list.GroupBy(a => a).SelectMany(ab => ab.Skip(1).Take(1)).ToList();
It will be more efficient then the one using Where(g => g.Count() > 1) and will return only one element from every group. | unknown | |

Hard to say without experimentation how important those differences might be.
I highly recommend logging your program in Process Monitor and seeing what if any errors you get in the log. This is usually how I identify tricky manifest problems. | unknown | |
d15720 | val | if you're using nuxt.js (which I suppose you do since you have the tag on your question), it's pretty easy, just add the following in your nuxt.config.js:
vuetify: {
defaultAssets: false,
treeShake: true,
icons: {
iconfont: 'mdiSvg', // --> this should be enough
// sideNote: you can also define custom values and have access to them
// from your app and get rid of the imports in each component
values: {
plus: mdiPlus, // you have access to this like $vuetify.icons.values.plus from your component
}
}
}
for the values to work you just have to import the appropriate icon in the nuxt.config.js like:
import { mdiPlus } from '@mdi/js'
or if you don't like the custom values you can import the needed icons for each component in the component itself and use them there like:
import { mdiPlus } from 'mdi/js'
...
data() {
return {
plusIcon: mdiPlus
}
}
A: What I ended up doing currently is to have all the svg in @mdi/svg package and use that as an img src. That way, I won't have to deal with dynamically importing it from @mdi/js and hoping for a treeshake. | unknown | |

d15722 | val | Docotic.Pdf library can be used for your task. Please see my answer for similar question.
Disclaimer: I work for the company that develops Docotic.Pdf library.
A: 1) Create your own PDF "parser":
http://www.quick-pdf.com/pdf-specification.htm
Probably could be minimal if you just need text data and not any of the formatting.
2) Find a library in your language of choice that can "natively" read .pdfs (tons of them out there).
3) use a pre-built tool (like pdf2text or pdfgrep): https://unix.stackexchange.com/questions/6704/grep-pdf-files
A: If your requirement is to search a for a word and replace it, you can go for Aspose.pdf.Kit
A: Poppler contains tools to extract text from a pdf document. Use it to search on documents.
A: In Java and C#, you can do that with iText, if the pdf file is not locked.

d15723 | val | GenPass.replace(GenPass[Pos],number) will replace every occurrence of the character at GenPass[Pos] with the value of number. You need to make sure you replace one character at a time.
A: Create a list of all chars and a list with all nums, then just pick one by using list.pop(randint(0, len(list) - 1), you will always pick a different letter / number like this but you will also be limited to 10 digits (0-9) and 20-something letters. | unknown | |
d15724 | val | Solution from @nik will work only for bash. For sh will work:
before_script:

A: We found a solution using indirect expansion (bash feature):
before_script:
- variableName=${GITLAB_USER_ID}_CI_K8S_PROJECT
- export wantedValue=${!variableName}
But we also recognised, that our setup was somehow stupid: It does not make sense to have multiple branches for each user and use prefixed variables, since this leads to problems such as the above and security concerns, since all variables are accessible to all users.
It is way easier if each user forks the root project and simply creates a merge request for new features. This way there is no renaming/prefixing of variables or branches necessary at all.
A: Something like this works (on 15.0.5-ee):
variables:

SELECT [CustomerNo],
(ListOf('SELECT [UpdateDate] FROM StatusTbl WHERE CustomerNo = ' + CStr([CustomerNo]))) AS UpdateDates

d15726 | val | Use the anyString() argument matcher:
when(iplayer.capture(Mockito.anyString())).thenReturn(true); | unknown | |
d15727 | val | Right now, the only way is via a global option, MvcOptions.AllowEmptyInputInBodyModelBinding. It defaults to false, so you just need to do:
services.AddControllers(o =>
{
o.AllowEmptyInputInBodyModelBinding = true;
});
A: There is now an easier way (since 5.0-preview7)
You can now achieve this per action method, by configuring a FromBodyAttribute property named EmptyBodyBehavior
Demonstration:
public IActionResult Post([FromBody(EmptyBodyBehavior = EmptyBodyBehavior.Allow)] MyModel model)
Thanks to LouraQ's comment, which guided me towards the above answer on github
A: I'm not sure about your final intention, but if you don't want to choose the content-type, you can pass an empty json string.
At this time, the user is not empty, but the content of it's field's value is null, and the final result is the same. Maybe you You can try it.

d15728 | val | Using dplyr, we can do this after converting the 'MES_ZOO' column to character class as the zoo class is not supported within the mutate (using dplyr_0.4.1.9000). We group by 'FILIAL_CODE', get the lead of columns MES_ZOO to DEVOLUCIONES using mutate_each, change the column names and left_join with the original dataset.
df$MES_ZOO <- as.character(df$MES_ZOO)
library(dplyr)
df %>%
group_by(FILIAL_CODE) %>%
mutate_each(funs(lead), MES_ZOO:DEVOLUCIONES)%>%
setNames(., c(names(.)[1:2], paste0('NEW_', nm1))) %>%
left_join(df, .)
Or we could use shift from the devel version of 'data.table' i.e. v1.9.5 (Instructions to install the devel version are here. We convert the 'data.frame' to 'data.table' (setDT(df)). Specify the columns to shift in the .SDcols, use shift with option type='lead' grouped by 'FILIAL_CODE'. Create new columns by assigning (:=)
library(data.table)#v1.9.5+

d15729 | val | I really don't know why you said "I can't just change view frames". Of course you can!
The approach I always take to this scenario (where your view's height is variable) is to declare a yOffset property and based on this I place my content at the right y position.
@property (nonatomic, assign) int yOffset;
Then inside the init method I initialize this property to either 0 or some predefined initial margin.
_yOffset = TOP_MARGIN;
Then consider the following scenario: a user profile with n number of skills. This is how you would use the yOffset property.
for (int i=0; i<n; ++i)
{
// place the skillView at the right 'y' position
SkillView *skillView = [[SkillView alloc] initWithFrame:CGRectMake(0,self.yOffset,300,50)];
// configure the skillView here
[self.view addSubview:skillView];
// Don't forget it has to be "+=" because you have to keep track of the height!!!
self.yOffset += skillView.frame.size.height + MARGIN_BETWEEN_SKILLS;
}
And then imagine the user profile has c number of Education entries; same thing:
for (int i=0; i<c; ++i)
{
// place the educationView at the right 'y' position
EducationView *educationView = [[EducationView alloc] initWithFrame:CGRectMake(0,self.yOffset,300,50)];
// configure the educationView here
[self.view educationView];
// Don't forget it has to be "+=" because you have to keep track of the height!!!
self.yOffset += educationView.frame.size.height + MARGIN_BETWEEN_EDUCATIONS;
}
Finally, when all your subviews have been added you have to change the frame of the containing view. (Because when you created it you couldn't know upfront how tall it was going to be)
CGRect viewFrame = self.view.frame;
viewFrame.size.height = self.yOffset + BOTTOM_MARGIN;
self.view.frame = viewFrame;
And that's it.
Hope this helps!
A: As you've stated, manually updating the frames is a lot of work and is the old way of doing things. The new better way as you've also said is to use auto layout. Describing how to use auto layout to position your views would require more specific information on how you want it to look but there are some awesome tutorials out there on the web! Here's one of many:

d15730 | val | Yes. You can do this pretty easily with Twisted. Just have one of the peers act like a server and the other one act like a client. In fact, the twisted tutorial will get you most of the way there.
The only problem you're likely to run into is firewalls. Most people run their home machines behind SNAT routers, which make it tougher to connect directly to them from outside. You can get around it with port forwarding though.
A: Yes, each computer (as long as their on the same network) can establish a server instance with inbound and outbound POST/GET.
A: I think i am way too late in putting my two bits here, i accidentally stumbled upon here as i was also searching on similar lines. I think you can do this fairly easily using just sockets only, however as mentioned above one of the machines would have to act like a server, to whome the other will connect.
I am not familiar with twisted, but i did achieved this using just sockets. But yes even i am curious to know how would you achieve peer2peer chat communication if there are multiple clients connected to a server. Creating a chat room kind of app is easy but i am having hard time in thinking how to handle peer to peer connections. | unknown | |
d15731 | val | Your query is definitively far from being optimized. Try this instead:
seismic2DSurvey.EndsAndBends = winPicsDbContext.Locations

seismic2DSurvey.SurveyLocations = null; | unknown | |
d15732 | val | After reading the Quirksmode article on the subject, I realized that the problem was exactly what was being described there - the function was being referred instead of copied. From what I gathered, it's impossible to have inline JS work like I wanted for multiple instances on a single page.
My solution was to extract the JS from the HTML tags and make it into functions. I used some jQuery to do so (because jQuery!). :p
Here's the HTML:
<input
class="span1 hasDefaultValue"
type="text"
name="abc"
value="25"
placeholder="25">
And the JS:
<script type="text/javascript">
function fieldFocus()
{
if (this.value==this.defaultValue)
{
this.value='';
}
else
{
this.select();
}
}
function fieldBlur()
{
if (!this.value)
{
this.value=this.defaultValue;
}
}
$(document).ready(function() {
$("input.hasDefaultValue").click(fieldFocus);
$("input.hasDefaultValue").blur(fieldBlur);
});
</script>
I'm sure that can be made more streamlined, but I wanted to post the answer ASAP. I might update with a streamlined solution later. | unknown | |
d15733 | val | Ok, I'm finally done with it. I am a fool, really.
In the Manifest.mf, section "Import-Package", don't forgot to add android.content
It now works perfectly ;) | unknown | |
d15734 | val | I ended up using inheritance to fix my issue. Although I have objects of many types, I created a "baseObject" class that contains the fields I needed for this to be successful. I was then able to use the following:
for obj in objectStack{
let obj2 = obj as! baseObject
fieldArrays[objectType]!.append(obj2.name.value)
}
I also used the solution here to use a dictionary to populate the correct array using the "didSet" event on the dictionary. | unknown | |
d15735 | val | @addy.first.street should work, as it is list of Adress classes containing only one member.
For displaying each street for more adresses in list:
@addy.each do |address|
puts address.street
end
or
list_of_streets = @addy.map { |address| address.street }
Edit:
When you have problem identifying what class you have, always check object.class. When you just use object in IRB, then you see output from object.inspect, which doesn't have to show class name or even can spoof some informations. You can also call object.methods, object.public_methods.
And remember that in Ruby some class is also an instance (of Class class). You can call @addr.methods to get instance methods and @addr.class.methods to get class methods.
Edit2:
In Rails #find can take as first parameter symbol, and if you pass :first of :last, then you'll get only one object. Same if you pass one integer (id of retrieved object). In other cases you get list as result, even if it contains only one object. | unknown | |
d15736 | val | found a solution. The tricky bit was to get the bookmarklet to see inside an iframe! see this link: How to pick element inside iframe using document.getElementById
so to manage the zoom in the iframe list this is the working example. In the link above I developed this further to make it a numbered list but the code is below:
javascript:(function(){ var style = document.createElement('style'), styleContent = document.createTextNode('.notifications-list--cMVsqVbKkaXV4SQ {zoom: 0.8!important;}'); style.appendChild(styleContent); var caput = document.getElementById('xm-feed-iframe').contentWindow.document.getElementsByTagName('head'); caput[0].appendChild(style); })();
to create a numbered list:
javascript:(function(){ var style = document.createElement('style'), styleContent = document.createTextNode('ul.notifications-list--cMVsqVbKkaXV4SQ li {zoom: 1.0!important; counter-increment: my-counter !important; } ul.notifications-list--cMVsqVbKkaXV4SQ li::before { content: counter(my-counter) \". \" !important; color: red !important; font-weight: bold !important; margin-left: 10px}'); style.appendChild(styleContent); var caput = document.getElementById('xm-feed-iframe').contentWindow.document.getElementsByTagName('head'); caput[0].appendChild(style); })();
Just for awareness, I've tried to do this using TamperMonkey but struggled and gave up upon finding a bookmarklet option (see this thread: Use Tampermonkey to add or append a number to each line of a list). I will loop back to this thread though and see if I can get it working (with the aid of stackoverflow users!).

d15738 | val | Save yourself the trouble of using a regex where you don't need one and just use:

i := strings.LastIndex(url, "/")
if i != -1 {

A: I am not that much familiar with golang till days. May be you can go with replace instead of split. For example using the following pseudocode.
Make a regex .*/ and then replace it with your string.
reg.ReplaceAllString(url, "")
This will replace anything before the last / and you'll have the repo.git | unknown | |

Typescript does not know that you are trying to create a config object for Axios. You can explicitly type the entire object as AxiosRequestConfig, or you could explicitly type responseType: 'json' to be of type ResponseType.
const config: AxiosRequestConfig = {
headers: {
'X-Requested-With': 'XMLHttpRequest',

d15741 | val | You're going to need to be more specific -- the way the question is now it's basically impossible to determine what you're after.
Do you need to transfer a file from a Windows Mobile handheld to a Windows PC? Over what type of connection (are they on the same 802.11 network) ?
You need more details or no one will be able to even attempt to help you.
A: So, if what I gather is correct, you want to plug a device with your app on it into a PC and then be able to push files to the PC from the device without having to install anything over on the PC. Is that correct? If so, the next question is are you insane?
It's not possible, and for very good reason. You don't see any potential security problems with being able to just plug a device into a PC and push files up to the PC without the user having to explicitly have installed something to receive that data? I could write a simple attack app that would fill up the PC's hard drive in about 5 minutes.
A: A vanilla version of this is to just use the Active Sync synchronization folders. If you on the device save a file to the device synch folder, then Active Sync will move it over to the PC synch folder automatically. | unknown | |
d15742 | val | Here's the code for automatic granting the SYSTEM_ALERT_WINDOW permission to the package. To run this code, your Android application must be system (signed by platform keys).

d15745 | val | Scipy's
curve_fit()
uses iterations to search for optimal parameters. If the number of iterations exceeds the default number of 800, but the optimal parameters are still not found, then this error will be raised.
Optimal parameters not found: Number of calls to function has reached maxfev = 800
You can provide some initial guess parameters for curve_fit(), then try again. Or, you can increase the allowable iterations. Or do both!
Here is an example:
popt, pcov = curve_fit(exponenial_func, x, y, p0=[1,0,1], maxfev=5000)
p0 is the guess
maxfev is the max number of iterations
You can also try setting bounds which will help the function find the solution.
However, you cannot set bounds and a max_nfev at the same time.
popt, pcov = curve_fit(exponenial_func, x, y, p0=[1,0,1], bounds=(1,3))
Source1: https://github.com/scipy/scipy/issues/6340
Source2: My own testing and finding that the about github is not 100% accurate
Also, other recommendations about not using 0 as an 'x' value are great recommendations. Start your 'x' array with 1 to avoid divide by zero errors.
A: Curve_fit() uses iterations to search for optimal parameters. If the number of iterations exceeds the set number of 1000, but the optimal parameters are still not available, then this error will be raised. You can provide some initial guess parameters for curve_fit(), then try again.
A: Your original data is t1 and F1. Therefore curve_fit should be given t1 as its second argument, not t.
popt, pcov = curve_fit(func, t1, F1, maxfev=1000)
Now once you obtain fitted parameters, popt, you can evaluate func at the points in t to obtain a fitted curve:
t = np.linspace(1, 3600 * 24 * 28, 13)
plt.plot(t, func(t, *popt), label="Fitted Curve")
(I removed zero from t (per StuGrey's answer) to avoid the Warning: divide by zero encountered in log.)

d15751 | val | Actually, in OpenCV there is a specific way to do that. You can write an object in an XML file as follow:
CvFileStorage* storage = cvOpenFileStorage("globalHistogram.xml", 0, CV_STORAGE_WRITE);
cvWrite(storage, "histogram", global_histogram);
and read is as such:
CvHistogram* global_histogram;
CvFileStorage* storage = cvOpenFileStorage("globalHistogram.xml", 0, CV_STORAGE_READ);
global_histogram = (CvHistogram *)cvReadByName(storage, 0, "histogram" ,0);
A: The Boost Serialization library is pretty nice. It may do what you want. http://www.boost.org/doc/libs/1_49_0/libs/serialization/doc/index.html
A: 1) Decide on a file format, plan it at the byte level (If an existing format is suitable, prefer it).
2) Write out the data in the file format you decided on.
A: You can add a method to the class called Serialise, something along the lines of the following:
CvHist::Serialise( std::string fName, bool read )
{
if ( read )
{
std::ifstream fStream( fName );
// Read in values from file, eg:
fStream >> this->param1;
fStream >> this->param2;
// ...etc
}
else
{
std::ofstream fStream( fName, ios::trunc ); // (ios::trunc clears file)
// Read out values into file, eg:
fStream << this->param1;
fStream << this->param2;
// ...etc
}
}
Note, the order is important - the order that you read the various parameters from the file must match the order you write parameters to the file. Also remember to #include <fstream>
Now, to create a CvHist object populated with data from a file data.txt you can simply write this:
CvHist object;
object.Serialise( "data.txt", true );

d15752 | val | The issue is that you're using the actions-on-google library for fulfillment, which only creates results that are valid on the Google Assistant.

d15753 | val | I have a quick guess that I'll try to flesh out if I get time today.
I suspect that the Forms App was built expecting to need to find any custom ddm-type modules and display them in the UI for selection. The Structures JSP is probably not updated to automatically expect to need to to find new types. So, I'm going to guess that there's a JSP that you need to modify somewhere in a dynamic-data-mapping-*-web module. Once you find what you need to modify and where it is, you'll be able to do that with a JSP override fragment. see here: https://dev.liferay.com/develop/tutorials/-/knowledge_base/7-0/overriding-a-modules-jsps
Hopefully that at least helps you direct your research into this matter. | unknown | |
d15754 | val | You have 4 arguments in your render of which 2 is context. It needs only one dictionary with context or you can make a context dictionary variable and pass it as argument in render.
Try this:
from django.shortcuts import render, get_object_or_404
from CGI.models import tank_system, ambient
def index(request):
tank = tank_system.objects.all()
room = ambient.objects.all()
return render(request, 'CGI/Pages/DashBoard.html', {'tank': tank,'room': room})
OR
from django.shortcuts import render, get_object_or_404

tank = tank_system.objects.all()
room = ambient.objects.all()
context = {
'tank': tank,
'room': room
}
return render(request, 'CGI/Pages/DashBoard.html',context)
A: You can pass data using two different ways
def index(request):
tank = tank_system.objects.all()
room = ambient.objects.all()
return render(request, 'CGI/Pages/DashBoard.html', {'tank': tank,'room': room})
or
return render(request, 'CGI/Pages/DashBoard.html', locals())
locals() stands for get all local variable/objects and pass to the html as context
A: In your index method, make changes as:

tank = tank_system.objects.all()
room = ambient.objects.all()
return render(request, 'CGI/Pages/DashBoard.html', {'tank': tank, 'room': room}) | unknown | |
d15755 | val | Try s.ToString().Replace(@"\""", "\"").
The @ tells C# to interpret the string literally and not treat \ as an escape character. "\"" as the second argument uses \ as an escape character to escape the double quotes.
You also don't need to call ToString() if s is already of type string.
Last but not least, don't forget that string replacement is not done in place and will create a new string. If you want to preserve the value, you need to assign it to a variable:
var newString = s.ToString().Replace(@"\""", "\"");
// or s = s.Replace(@"\""", "\""); if "s" is already a string.
A: Update
if you have a string containing ", when you view this string in the Visual Studio immediate window it will display it as \". That does not mean that your string contains a backslash! To prove this to yourself, use Console.WriteLine to display the actual value of the string in a console, and you will see that the backslash is not there.
Here's a screenshot showing the backslash in the immediate window when the string contains only a single quote.
Original answer
Three things:
*
*Strings are immutable. Replace doesn't mutate the string - it returns a new string.
*Do you want to replace a quote "\"" or a backslash followed by a quote "\\\"". If you want the latter, it would be better to use a verbatim string literal so that you can write @"\""" instead.
*You don't need to call ToString on a string.
Try this:
s = s.Replace(@"\""", "\"");
See it on ideone.
A: Ironically, you need to escape your quote marks and your backslash like so:
s.ToString().Replace("\\\"", "\"");
Otherwise it will cat your strings together and do the same as this (if you could actually use single quotes like this):
s.ToString().Replace('"', "");
(your second string has four quotes... that's why you're not getting a compile error from having """) | unknown | |

d15757 | val | You should not run animation off of the UI thread ("main" thread) - you should load your content in another thread by using a Loader (or something similar) and play the animation on the UI thread. That's what it's for.

d15758 | val | Because your else case says:
unique [] = []
unique (x:xs) = if (fst x) == (snd x) then unique (xs) else x:[]
It thus says if fst x is not equal to snd x, then we return x : [] (or shorter [x]), and we are done. So it does not perform recursion on the rest of the list.
We can solve this by adding recursion on the rest of the list, like:
unique [] = []
unique (x:xs) = if fst x == snd x then unique xs else x : unique xs
That being said, we can use a filter here, like:
unique :: Eq a => [(a, a)] -> [(a, a)]
unique = filter (\(x, y) -> x /= y)
or even shorter:
unique :: Eq a => [(a, a)] -> [(a, a)]
unique = filter (uncurry (/=))
We thus retain all elements for which the first element x is not equal to the second element y. | unknown | |

d15760 | val | Traffic is only routed within the cluster by default, so if the application on C is not part of the cluster, then ingress and egress won't be possible between the A/B nodes and C. This is all controlled by application's service configuration.
To route ingress and egress traffic from/to outside the cluster, you'll need to configure the service of your application. One of the easier ways to do this is to use the type LoadBalancer service.
You can also use the type NodePort service, which will expose the service on a mapped port in the range of 30000 - 32767 across all nodes.
Lastly, you can assign an External IP to the service to allow outside traffic into the cluster.
Hope this helps! | unknown | |
d15761 | val | In your code: try with n=10000 and you'll see more of a difference (a factor of almost 10 on my machine).
These things related with allocation are most noticeable when the size of your variable is large. In that case it's more difficult for Matlab to dynamically allocate memory for that variable.
To reduce the number of operations: do it vectorized, and reuse intermediate results to avoid powers:
y = (1 + x.*(-3/5 + x.*(3/20 - x/60))) ./ (1 + x.*(2/5 - x/20));
Benchmarking:
With n=100:
Parag's / venergiac's solution:
>> tic
for count = 1:100
y=(1-(3/5)*x+(3/20)*x.^2 -(x.^3/60))./(1+(2/5)*x-(1/20)*x.^2);
end
toc
Elapsed time is 0.010769 seconds.
My solution:
>> tic
for count = 1:100
y = (1 + x.*(-3/5 + x.*(3/20 - x/60))) ./ (1 + x.*(2/5 - x/20));
end
toc
Elapsed time is 0.006186 seconds.
A: You don't need a for loop. Replace the for loop with the following and MATLAB will handle it.
y=(1-(3/5)*x+(3/20)*x.^2 -(x.^3/60))./(1+(2/5)*x-(1/20)*x.^2);
This may give a computational advantage when vectors become larger in size. Smaller size is the reason why you cannot see the effect of pre-allocation. Read this page for additional tips on how to improve the performance.
Edit: I observed that at larger sizes, n>=10^6, I am getting a constant performance improvement when I try the following:
x=0:1/n:1;
instead of using linspace. At n=10^7, I gain 0.05 seconds (0.03 vs 0.08) by NOT using linspace.

d15762 | val | Ransack uses a predicate added on to the end of the field you're searching for to indicate how to search for it. If you have an attribute of :state on your model, you could search for states that match to 'expired' or 'deleted' using form.select :state_match, where the _match says to match records with state of whatever you selected. (Things like _cont (contains) or _start (starts with)).
Ransack makes SQL queries to find records, so if you had an attribute on your model like :deleted_at you could search by presence or lack-of. It won't look at methods, just the information stored in the db.

If that's insufficient for your use case, you'll have to expand your question to include code and output showing what Jobs.last is supposed to return, whatever errors you're getting from the route currently, and what you think the route's output ought to look like if you're expecting a MIME type other than text/plain. | unknown | |
d15764 | val | You need to create the database and the sde login manually using e.g. pgAdmin, and grant the rds_superuser group role to the sde login. Also create a schema named sde in your database, and make the sde login the owner of that schema.
Then you can create a .sde database connection in ArcCatalog using the sde login and, importantly, the *.rds.amazonaws.com hostname. Finally you can run the Enable Enterprise Geodatabase using this connection as your input.
This only works if you connect to the database using the *.rds.amazonaws.com hostname. Apparently, ESRI uses the hostname to determine if the database in question is an RDS server.
Once you've enabled the geodatabase you can connect to it with .sde connections using other dns aliases as well.

d15765 | val | Is it even possible to set a Date object with a different timezone?
No, it's not possible. As its javadoc describes, all the java.util.Date contains is just the epoch time which is always the amount of seconds relative to 1 january 1970 UTC/GMT. The Date doesn't contain other information. To format it using a timezone, use SimpleDateFormat#setTimeZone()
A: getTime is an Unix time in seconds, it doesn't have the timezone, i.e. it's bound to UTC. You need to convert that time to the time zone you want e.b. by using DateFormat.
import java.util.*;
import java.text.*;
public class TzPrb {
public static void main(String[] args) {
Date d = new Date();
System.out.println(d);
DateFormat df = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
df.setTimeZone(TimeZone.getTimeZone("Australia/Sydney"));

df.setTimeZone(TimeZone.getTimeZone("Europe/London"));

d15766 | val | I took a look at the src and I see that the PhoneGap.exec calls in analytics.js does not match the plugin name. You have two ways to fix this.
*
*In plugins.xml make the plugin line:
<plugin name="GoogleAnalyticsTracker" value="com.phonegap.plugins.analytics.GoogleAnalyticsTracker"/>
*Or in analytics.js replace all instances of 'GoogleAnalyticsTracker' with 'Analytics'
This is a bug in the way the code is setup in github. You should message the author to get them to fix it.
A: Rather than using the PhoneGap plugin, I would recommend using the Google Analytics SDK for tracking usage of application developed using PhoneGap or any web based mobile app.

Instead of this:
context.arc(screen.availWidth/2,screen.availHeight/2, hours_radius, 0, RADcurrentTime.hours);

d15773 | val | Python 3 now exposes the methods to directly set the affinity

>>> os.sched_setaffinity(0, x)
>>> os.sched_getaffinity(0)
{0, 1, 2, 3}
A: After some more googling I found the answer here.
It turns out that certain Python modules (numpy, scipy, tables, pandas, skimage...) mess with core affinity on import. As far as I can tell, this problem seems to be specifically caused by them linking against multithreaded OpenBLAS libraries.
A workaround is to reset the task affinity using
os.system("taskset -p 0xff %d" % os.getpid())
With this line pasted in after the module imports, my example now runs on all cores:
My experience so far has been that this doesn't seem to have any negative effect on numpy's performance, although this is probably machine- and task-specific .
Update:
There are also two ways to disable the CPU affinity-resetting behaviour of OpenBLAS itself. At run-time you can use the environment variable OPENBLAS_MAIN_FREE (or GOTOBLAS_MAIN_FREE), for example
OPENBLAS_MAIN_FREE=1 python myscript.py
Or alternatively, if you're compiling OpenBLAS from source you can permanently disable it at build-time by editing the Makefile.rule to contain the line
NO_AFFINITY=1
A: This appears to be a common problem with Python on Ubuntu, and is not specific to joblib:
*
*Both multiprocessing.map and joblib use only 1 cpu after upgrade from Ubuntu 10.10 to 12.04
*Python multiprocessing utilizes only one core
*multiprocessing.Pool processes locked to a single core
I would suggest experimenting with CPU affinity (taskset). | unknown | |

d15776 | val | You have the lot of inefficiences in code that is detracting from an issue at hand.
Ex:
jsonDump = json.dumps(jsonData)
actualJson = json.loads(jsonDump)
What is the point? To equal just as:
actualJson = jsonData
Or even:
actualJson = jsonData.copy()
Next:
finalObject = {}
finalObject['CompanyId'] = actualJson.get("CompanyId")
This can be to:
finalObject = {'CompanyId' : actualJson.get("CompanyId") }
Then:
if (i.get("period").get("instant")):
But i.get if not there, is None, so I think for in case your error, then don't handle as such:
if (i["period"].get("instant")):
And then also:
f"{property}"
Specifically, here:
mList.append({f"{property}": final[f"{property}"]})
But what is property? I think it's just a string:
property
So:
mList.append({property: final[property]})
A: What I see from your data:
We know that a dictionary does not have duplicate keys:
I want to show with an example:
d={}
list_of_dict=[{1:'a',2:'b'},{1:'c'}]
Now, when you apply update:
for x in list_of_dict:
d.update(x)
Now, you will get:
#{1: 'c', 2: 'b'}
You see update() will override the the value of key 1 from 'a' to 'c'.

A: You are using absolute left values for your animation rather than relative values.
Try using this syntax:
jQuery(this).animate({ left : '+=25px' }, 10).animate({ left : '-=25px' }, 10) ;
currently you are bouncing the element around absolute position -25 to 25, and leaving it up against the left border. | unknown | |

d15780 | val | I figured out the issue. You need to add
<ion-overlay></ion-overlay>
to your app.html. I saw that no where in the documentation. | unknown | |
d15781 | val | Set navigationController?.navigationBar.isTranslucent = false.
You can also achieve this by unchecking Translucent from storyboard.
A: Change navigation bar to Opaque instead of Translucent.
Swift
self.navigationController?.navigationBar.isTranslucent = true
Objective-C
[[UINavigationBar appearance] setTranslucent:YES];
Please find in image.
And if you are setting navigations background color then change
navigation background color instead of tint color. | unknown | |
d15782 | val | You can use the aggregate function MAX in having:
select client.name from client inner join stayed
on client.client_id = stayed.client_id inner join
room on stayed.room_id= room.room_id
Group by name
having MAX(room.price) < 5000
A: I recommend not exists for this:
select c.name
from client c
where not exists (select 1
from stayed s join
room r
on s.room_id = r.room_id
where c.client_id = s.client_id and
r.price >= 500
);
This is almost a directly translation of your question. Note: If you attempt inner joins for this, then you will miss clients who have stayed in no rooms at all. According to your question, you would miss these clients in the result set.
A: This is another approach
SELECT c.Name
FROM client
WHERE c.client_id NOT IN (
SELECT s.client_id
FROM stayed s INNER JOIN room r
ON s.room_id = r.room_id
WHERE r.price > 5000) | unknown | |
d15783 | val | If forgot to use the (SELECT ATTRIBUTES_DE_AT FROM DUAL) subquery inside the XMLTYPE...
SELECT DISTINCT P.SKU, SUBSTR(X.ATTRIBUTENAME, 14, 3) ATTRIBUTECODE, X.ATTRIBUTEVALUE
FROM PRODUCT@ISPSTAG2 P,
XMLTABLE('/attrs/attr'
PASSING XMLTYPE(REGEXP_REPLACE(**(SELECT ATTRIBUTES_DE_AT FROM DUAL)**, '<attr name="longDescription">.*?<\/attr>'))

WHERE X.ATTRIBUTENAME LIKE 'Z_CA%'
AND DN(DOMAINID) = 'AT'
AND SKU NOT LIKE 'OFF_%' AND SKU NOT LIKE 'PDT%'
AND (SELECT ATTRIBUTES_DE_AT FROM DUAL) IS NOT NULL;
The thing I don't understand is that when don't use the subquery in the IS NOT NULL filter I have the the ORA-22992 error (using distant LOB), so why I have a different error not using the dual subquery, which is the same distant LOB ?
Anyway for you for your time/help :) | unknown | |
d15784 | val | You can't really do anything -- I guess Isilon's SMB implementation doesn't support certain things (that would've preserved timestamps).
I simply added FlushFileBuffers() before SetFileInformationByHandle() and made sure there are no related race conditions in my code. | unknown | |
d15785 | val | You can send invites between android and iOS. They are linked using the developer console (console.developers.google.com). Both the android app and the iOS app need to be in the same console project. If there is only one of each, then when sending across platforms it's unambiguous which to choose and you can just send an invite. The app invite service will send the proper short links(goo.gl/...) to install/launch the proper app per platform.
If there are multiple instances of a iOS and/or Android apps in the console project, then the client ID must be sent with the invite using Api call setOtherPlatformsTargetApplication(...) so that app invite service knows which of the console apps should be selected.
For same platform, i.e. android to android, the app selected will match the app that sent the invitation, so same platform is not ambiguous. | unknown | |
d15786 | val | Perhaps "export option" instead of "export searchBar".
A: Try this code:
#!/bin/bash -x
func()
{
echo "
Choose
1 - Option 1
2 - Option 2
"
echo -n " Enter selection: "
read select
case $select in
1 )
echo " Option 1 chosen"
OPTION=one
export OPTION
./genScript.sh
;;
2 )
echo " Option 2 chosen"
OPTION=two
export OPTION
./genScript.sh
;;
esac
}
clear
func
#!/bin/bash
func2()
{
if [ ${OPTION} == "one" ] ; then
echo "Option one"
else
echo "Option two"
fi
}
func2
and finally run the configScript.sh with this command: . ./configScript.sh from the shell.
A: I wonder if you actually have a comment line before your shebang line: #! must be the first 2 characters in the file.
I also wonder if you're actually executing these scripts with sh instead of bash. Change
[ "$option" == "one" ]
to
[[ $option == "one" ]]
Instead of exporting, the config script needs to store the value:
declare -p OPTION > ~/.my_config
And then the other script can do
. ~/.my_config
if [[ $OPTION == "one" ]]; ... | unknown | |
d15787 | val | To get two types of access you either need to combine two containers... or reuse a library that combines containers for you.
Boost.MultiIndex was invented for precisely this kind of needs.
The basics page shows an example that has employees accessible by id (unique) and sorted by name (non-unique), which is pretty much what you are going for.
The key extractors are perhaps not obvious. Supposing that your thread ressemble:
class Thread {
public:
std::size_t id() const;
std::size_t priority() const;
...
};
You should be able to write:
#include <boost/multi_index_container.hpp>
#include <boost/multi_index/ordered_index.hpp>
#include <boost/multi_index/const_mem_fun.hpp>
#include <boost/multi_index/member.hpp>
// define a multiply indexed set with indices by id and name
typedef multi_index_container<
Thread,
indexed_by<
ordered_unique<
const_mem_fun<Thread, std::size_t, &Thread::id>
>,
ordered_non_unique<
const_mem_fun<Thread, std::size_t, &Thread::priority>
>
>
> ThreadContainer;
Which defines a container of thread uniquely identified by their id() and sorted according to their priority().
I encourage you to play around with the various indexes. Also, if you provide friend access to your class or specific getters that return mutable references, then using mem_fun instead of const_mem_fun you will be able to update your objects in place (for example, change their priority).
It's a very complete (if daunting) library.
A: Best solution is possibly std::map,, providing you a key / value pair. In your scenario the key has the type of your _id and the value the type Thread (assuming this is the name of your class). By copying all values to a std::vector you can sort by _priority with std::sort and a predicate.
A: An easy solution would be to keep the std::unordered_map to provide the key --> thread lookup, and then use a std::set to implement your priority queue. | unknown | |
d15788 | val | Due to the \, make emits the recipe as a single line. This confuses the shell. Try this instead, using ; in place of the line terminator:
for i in a.h b.h ; \
do \
echo $i ; \
cp $i somedir ; \
done | unknown | |
d15789 | val | ratchet freak is right, it is a shallow copy. You can see the source to the dup function in dmd2/src/druntime/src/rt/lifetime.d. The function is called _adDupT.
It is a pretty short function where the main work is a call to memcpy(). Above the function, you can see a representation of an array: struct { size_t length; void* ptr; }
A jagged array would be an array of arrays, so the memory would look like [length0, ptr0, length1, ptr1, length2, ptr2....]
Since memcpy over those pointers doesn't follow them, that means slice.dup is a shallow copy.
This is generally true with anything that copies slices, it is always shallow copies unless you do something yourself. So struct A {char[] str; } A a, b; a = b; would also shallow copy, so assert(a.str is b.str).
If you want to do a deep copy, the simplest way is to just loop over it:
T[][] newArray;
foreach(item; oldArray)
newArray ~= item.dup;
(you can also preallocat newArray.length = oldArray.length and assign with indexes if you want to speed it up a bit)
A deep copy of a struct could be done with compile time reflection, though I prefer to write a clone method or something in there since it is a bit more clear.
I'm not aware of a phobos function with this premade. | unknown | |
d15790 | val | Your code will have bad performance if there will be many records in master detail table. Because you will have masterRecordCount * DetailRecordCount nested loop. So it will be better if you group and join in one query
var calculatedlist = from I in _entities.Investments
join IL in _entities.Investment_Line on I.ID equals IL.ParentID
group IL by new { I.ID } into g
select new {
InvestmentID = g.Key,
RefNo = g.Max(m => m.I.RefNo),
UserID = g.Max(m => m.I.UserID) ,
InvestedAmount = g.Max(m => m.I.InvestedAmount) ,
TotalAmount = g.Max(m => m.I.InvestedAmount) + g.Max(m => m.I.ProfitAmount),

d15791 | val | At some point someone has changed your code from making a POST request to making a GET.
GET puts all the data into the URL instead of putting it in the request body. URLs have a length limit. Go back to using POST and this problem will go away. Refer to the documentation for your HTTP client library to find out how to do this. | unknown | |
d15792 | val | I think you just want conditional aggregation:
select week, count(*) as total,
sum(case when pp = 'T' then 1 else 0 end) as num_pp,
sum(case when sen = 'T' then 1 else 0 end) as num_sen
from t
group by week;
A: In powerquery, something like this
let Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
#"Added Custom" = Table.AddColumn(Source, "Total", each "1"),
#"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Added Custom", {"week"}, "Attribute", "Value"),
#"Changed Type1" = Table.TransformColumnTypes(#"Unpivoted Other Columns",{{"Value", type text}}),
#"Replaced Value" = Table.ReplaceValue(#"Changed Type1","T","1",Replacer.ReplaceText,{"Value"}),
#"Replaced Value1" = Table.ReplaceValue(#"Replaced Value","F","0",Replacer.ReplaceText,{"Value"}),
#"Changed Type" = Table.TransformColumnTypes(#"Replaced Value1",{{"Value", type number}}),
#"Pivoted Column" = Table.Pivot(#"Changed Type", List.Distinct(#"Changed Type"[Attribute]), "Attribute", "Value", List.Sum)
in #"Pivoted Column" | unknown | |
d15793 | val | I would suggest in stead of adding the array list after you clear you instead do this
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
filteredShoppingList = (ArrayList<ShoppingListModel>)filterResults.values;
if (filterResults.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();

d15794 | val | The body has: min-height: 2000px; that's why there is extra space.. | unknown | |
d15795 | val | I'd like to generate the result like this:
from collections import Counter
age = [1,1,1,1,1,1,1,1,1,1.1,1.1,1.1,1.1,1.1,1.1,1.1,1.2,1.2,1.2]
c = Counter(age)
result = [[k]*v for k,v in c.items()]
print(result)
# Result would be:
# [[1, 1, 1, 1, 1, 1, 1, 1, 1], [1.1, 1.1, 1.1, 1.1, 1.1, 1.1, 1.1], [1.2, 1.2, 1.2]]
Line 3 means:
*
*Group the list according to the content of list,
*the item of Counter result looks like a dict, the key is age, while the value is frequency of each age.
Line 4 means:
*
*Iterate the item of Counter result, get the keys(k) and values(v)
*Create list of same value by [k]*v | unknown | |
d15796 | val | For caching data I would stick it in a file in IsolatedStorage.
It is a little more work, but you can write a simple enough wrapper around it.
It is conceivable that IsolatedStorageSettings.ApplicationSettings will one day be synced between devices using SkyDrive, this is the direction Microsoft are taking with Windows 8. So you should stick to using it for it's purpose which is application based settings. | unknown | |
d15797 | val | Our friend @AngocA seems to check into SO often but hasn't been checking this dangling question even though he did something to close it. Let's at least put his answer in here so folk know it's CLOSED by user. :) Courtesy of tonight's Point Pimp. :-D
"The problem was in another db2cmd session where there was an
infinitive loop. This created a scenario when new db2cmd session

d15798 | val | -2 is getting converted to unsigned integer. This will be equal to UINT_MAX - 1, which is definitely greater than 2. Hence, the condition fails and -1 is printed. | unknown | |
d15799 | val | just make vbo of points
and then
...
glVertexAttribPointer(.., 1, GL_FLOAT, GL_FALSE, 0, (void*)0);
glDrawArrays(GL_POINTS,0,.. );
Use math you have to assign each.
But it's not so easy. I think it can be done with deploy of second pair of shaders /vao. OpenGL multiple draw calls with unique shaders gives blank screen | unknown | |
d15800 | val | I found I can eliminate this problem simply by calling myPropertyGrid.ExpandAll(TRUE) at the end of the code where I initialize the property grid (InitPropertyGrid() for me). This seems to force all the properties to expand. | unknown |
