20,247,923 | I'm making a program that change the color of the background, for example, when I press white, change background to white, black to black, and so on... and after have pressed a button the others disappear and I have already done that but what I want to do is that each tap on the Textview the buttons appear/disappear. how can I do this?
this is my code
```
LinearLayout myLayout;
LinearLayout myLayout2;
// Declare UI elements
private Button firstButton;
private Button secondButton, thirdButton;
// private ImageView changeBackground;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
myLayout = (LinearLayout) findViewById(R.id.myLayout);
myLayout2 = (LinearLayout) findViewById(R.id.myLayout2);
// Initialize the UI components
firstButton = (Button) findViewById(R.id.button1);
// When we creating a button and if we expect that to use for event handling we have to set the listener
firstButton.setOnClickListener(this);
secondButton = (Button) findViewById(R.id.button2);
secondButton.setOnClickListener(this);
thirdButton = (Button) findViewById(R.id.button3);
thirdButton.setOnClickListener(this);
}
@Override
public void onClick(View v) { // Parameter v stands for the view that was clicked.
switch(v.getId()) {
case R.id.button1:
myLayout.setBackgroundColor(Color.WHITE);
myLayout2.setVisibility(View.INVISIBLE);
break;
case R.id.button2:
myLayout.setBackgroundColor(Color.BLACK);
myLayout2.setVisibility(View.INVISIBLE);
break;
case R.id.button3:
myLayout.setBackgroundColor(Color.RED);
myLayout2.setVisibility(View.INVISIBLE);
break;
}
}

``` | 2013/11/27 | ['https://Stackoverflow.com/questions/20247923', 'https://Stackoverflow.com', 'https://Stackoverflow.com/users/2958480/'] | the problem was that i was calling a function (one click) and then nothing triggered. I change the code and now it's working super! here you can check it out:
<http://bootply.com/97366>
View:
Is the same that in my question, but only changed the modal name to "myModal".
Js File:
```
$('#myModal').on('show', function() {
var id = $(this).data('id'),
username = $(this).data('usern');
$('#myModal .modal-body p').html("Desea eliminar al usuario " + '<b>' + username + '</b>' + ' ?');
})
$('.confirm-delete').on('click', function(e) {
e.preventDefault();
var id = $(this).data('id');
var user = $(this).data('title');
$('#myModal').data('id', id).modal('show');
$('#myModal').data('usern', user).modal('show');
});
$('#btnYes').click(function() {
var id = $('#myModal').data('id');
$.ajax({
url: 'deleteFrontUser',
type: 'POST',
data: 'id='+id,
success: function(html){
$('[data-id='+id+']').parents('tr').remove();
$('#myModal').modal('hide');
}
});
return false;
});
```
What i also did, was to add "data-title" atribute in the html, like this:
```
<td><a href="#" class="confirm-delete btn mini red-stripe" role="button" data-title="{$frontuser->username}" data-id="{$frontuser->id}">Eliminar {$frontuser->id} {$frontuser->username} </a></td>
```
data-title stores the username so jquery can sustract it later. Please notice that i'm using smarty template engine.
Hope this can help newbies like me :) | Try saving the id you pass there (I suppose it's the id of the user in the list) to a global variable which will be always overridden with the last id of the corresponding row where you pressed the delete button.
and then you can just call the modal like this:
```
$('#myModal3').modal('show');
```
After this you can get the id from the global variable and pass it to the ajax post |
1,214,269 | I created a console application using C# that references external DLLs. When I run it on my dev machine, everything works fine. On the production machine, I get a "type initiatization" error. Looking into this, it seems it may because the app can't find the referenced DLLs.
On my dev box, the referenced DLLs are in the GAC, but not on the production one. When removing the DLLs from the GAC on the dev box, the same error occurs (unless I run it from a local Visual Studio build in debug mode).
I'm more familiar with web site setups, and know there that the DLLs can be placed in the bin directory or the GAC so they can be found by the web application. But I'm not sure about how this works for console apps.
I'm reluctant to put the DLL into the GAC on the production box, as it's only needed for this one small application. Are there other ways for me to deploy the console app and have it find its required assemblies?
Here is the exception I'm getting:

162,148 | I recently transferred a virtualbox machine from my laptop to my recently reinstalled desktop. The image works fine on my laptop, but when I try to boot it on my new machine, I get dumped to an "EFI Shell" where it asks me about my hard drives rather than booting the machine. I want it to boot to the actual machine image rather than this shell. How can I fix this? | 2012/07/10 | ['https://askubuntu.com/questions/162148', 'https://askubuntu.com', 'https://askubuntu.com/users/74997/'] | It turns out that as I was messing around with getting the machine to load (due to Virtualization technologies being disabled), I clicked one too many items on the image settings page.
To fix this, go to the "Settings" page for the virtual machine, and click "System". Under the "motherboard" options, be sure that "Enable EFI (special OSes only)" is unchecked. Then click "OK", and try to boot the machine again. The option that was checked is basically how you get into the [EFI Interface](http://www.virtualbox.org/manual/ch03.html#efi). | 1. in Efi shell: `edit startup.nsh`
2. add line `FS0:\EFI\Path\To\Desired.efi`

27,812,897 | I have a Node / Mongoose / MongoDB project which I use Selenium WebDriver for integration tests. Part of my testcase setup is to wipe the database before each test. I accomplish this via command line using the method that's heavily accepted here [Delete everything in a MongoDB database](https://stackoverflow.com/questions/3366397/delete-everything-in-a-mongodb-database)
```
mongo [database] --eval "db.dropDatabase();"
```
The problem is however that after running this command, Mongo no longer enforces any unique fields, such as the following as defined by my Mongoose Schema:
```
new Mongoose.Schema
name :
type : String
required : true
unique : true
```
If I restart `mongod` after the `dropDatabase` then the unique constraints are enforced again.
However since my `mongod` is run by a separate process, restarting it as part of my test case set up would be cumbersome, and I'm hoping unnecessary. Is this a bug or am I missing something? | 2015/01/07 | ['https://Stackoverflow.com/questions/27812897', 'https://Stackoverflow.com', 'https://Stackoverflow.com/users/698289/'] | As you stated, your `mongod` (or multiple ones) is a separate process to your application, and as such your application has no knowledge of what has happened when you dropped the database. While the collections and indeed the database will be created when accessed by default, this is not true of all the indexes you defined.
Index creation actually happens on application start-up, as is noted in this passage from the documentation:
>
> When your application starts up, Mongoose automatically calls ensureIndex for each defined index in your schema. ...
>
>
>
It does not automatically happen each time a model is accessed, mostly because that would be excessive overhead, even if the index is in place and the server does nothing, it's still additional calls that you don't want preceeding every "read", "update", "insert" or "delete".
So in order to have this "automatic" behavior "fire again", what you need to do is "restart" your application and this process will be run again on connection. In the same way, when your "application" cannot connect to the `mongod` process, it re-tries the connection and when reconnected the automatic code is run.
Alternately, you can code a function you could call to do this and expose the method from an API so you could link this function with any other external operation that does something like "drop database":
```js
function reIndexAllModels(callback) {
console.log("Re-Indexing all models");
async.eachLimit(
mongoose.connection.modelNames(),
10,
function(name,callback) {
console.log("Indexing %s", name);
mongoose.model(name).ensureIndexes(callback);
},
function(err) {
if(err) throw err;
console.log("Re-Indexing done");
callback();
}
);
}
```
That will cycle through all registered models and re-create all indexes that are assigned to them. Depending on the size of registered models, you probably don't want to run all of these in parallel connections. So to help a little here, I use `async.eachLimit` in order to keep the concurrent operations to a manageable number. | Thanks to Neil Lunn for pointing out the pitfalls of `dropDatabase` and re-indexing. Ultimately, I went for the following command line solution, and removing the `dropDatabase` command.
```
mongo [database] --eval "db.getCollectionNames().forEach(function(n){db[n].remove()});"

153,204 | I am working with Goole map in a VF page.Consider that Account object has Geolocation field. Based on the user location I have mapped the center point in the map and got the bounds of the map using getBounds() function in javascript.
`GetBounds` returns two Geolocations SouthWest and NorthEast.
How I can query all the accounts within those two geolocations? | 2016/12/20 | ['https://salesforce.stackexchange.com/questions/153204', 'https://salesforce.stackexchange.com', 'https://salesforce.stackexchange.com/users/19084/'] | If you can get a latitude/longitude pair from those Geolocations on the page, you should be able to find records within a radius of those points via the `DISTANCE` and `GEOLOCATION` functions used in a `WHERE` clause. The specifics of these functions are discussed in the [Geolocation based SOQL Queries](https://developer.salesforce.com/docs/atlas.en-us.soql_sosl.meta/soql_sosl/sforce_api_calls_soql_geolocate.htm) documentation.
If the [release notes](https://developer.salesforce.com/releases/release/Summer15/queries) are correct, you can preform queries such as the ones below:
```
Double myLatitude = 10;
Double myLongitude = 10;
List accountList = [SELECT Id, Name, BillingLatitude, BillingLongitude FROM Account WHERE DISTANCE(My_Location_Field__c, GEOLOCATION(:myLatitude, :myLongitude), 'mi') < 10];
Location myLocation = Location.newInstance(10, 10);
Double myDistance = 100;
List accountList = [SELECT Id, Name, BillingLatitude, BillingLongitude FROM Account WHERE DISTANCE(My_Location_Field__c, :myLocation, 'mi') < :myDistance];
```
The key of these queries is in the `WHERE` clause. Querying based on the results of a query filtered by a formula to determine the distance between the specified point, provided by the javascript on your page, and the location of each record should provide the behavior you are looking for.
---
Below is an example of a page/controller which would be setup to perform these queries.
Page Example
============
```
<apex:actionFunction name="GetRecordsAtLocation" action="{!GetRecordsAtLocation}" rerender="ResultsPanel">
<apex:param name="Longitude" assignTo="{!Longitude}" value="" />
<apex:param name="Latitude" assignTo="{!Latitude}" value="" />
</apex:actionFunction>
<!-- ... -->
<script>
var someGeolocation = something.GetBounds();
GetRecordsAtLocation(someGeolocation.Longitude, someGeolocation.Latitude);
</script>
```
As you can see, you'll need a way to pass the values from your page's javascript, over to the controller. This is where using an `actionFunction` comes in handy.
Controller Example
==================
```
public List<Account> accountsAtLocation { get; set; }
public Double Longitude { get; set; }
public Double Latitude { get; set; }
public PageReference GetRecordsAtLocation() {
accountsAtLocation = [SELECT Id, Name, BillingLatitude, BillingLongitude FROM Account WHERE DISTANCE(My_Location_Field__c, GEOLOCATION(:Latitude, :Longitude), 'mi') < 10];
return null;
}
```
You'll need a function setup to perform the query based on values set by the `actionFunction`, and then save those records to a variable which you can access on the page. | Finally Google developer doc helped me. Here is the solution,
```
//Creating the map
var mapOptions = {center: myLatLng ,
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP};
//Link with page component
var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
//Get the bounds of the map this will return LatLngBounds
var bounds = map.getBounds();
ver newGeolocation = new google.maps.LatLng(13, 81);
//Bounds will check whether given geolocation exist within the bounds
if(bounds.contains(newGeolocation) {
//Got the location which exist within the current map bounds
}

In the *Garden of Peace*, Rabbi Shalom Arush says that a man cannot be a giver if he has lust towards his wife. That is, he should nullify all his lust towards his wife and only focus on giving to her.
Is this opinion unique to the Breslov way of thought or are there other opinions that support this idea? | 2015/12/09 | ['https://judaism.stackexchange.com/questions/66117', 'https://judaism.stackexchange.com', 'https://judaism.stackexchange.com/users/3006/'] | This discussion centers around the mishna in avos towards the end of chapter two (either mishna 12 or 17, depending on your print) "all your deeds should be lishem shomayim".
Rambam offers two different approaches between his pirush on the mishna and in his shmona perakim, which is echoed in the two different approaches in the shulchan aruch brought in shalom's answer. See there and the sources in Shalom's sources for a better understanding.
There is also the gemara in Bava Basra 16a which praises Avraham for having never concentrated on Sarah's beauty, brought in Rashi on Lech Licha 12 11. This would give credence to the no personal enjoyment approach.
This is all Midas Chasidus though. A possibly unattainable goal for which the true benefit is gained simply by a different approach to life. There are many examples in the Talmud where a wife's beauty is appreciated for shalom bayis. In fact the seffer chasidim says it is not allowed to marry someone one finds unattractive as he will spend the rest of his life secretly praying for her to die.
So as with all Midas Chasidus, a disclaimer is in order, not to ruin the main mitzvah while chasing chasing the extra credit. Especially when this mitzvah involves another human being who might not appreciate the lisheim shomayim approach, see the parenthetical story.
(Sad story disclaimer: I had a friend in yeshiva who was the type of masmid who actually learned in his sleep. Seriously. Actual gemara came out of his mouth in his sleep. He impressed all of us cynics. Well, a couple of years into his marriage his wife asked him\* what goes through his mind when they were together. He told her all his higher kavanos and all his lisheim shomayim intentions. She divorced him and took the kids.

The Shulchan Aruch in Or HaChaim uses very strong language about "only for her", but in Even HaEzer that does not appear. Most notably, the Aruch HaShulchan modifies the Shulchan Aruch's language from "only for her" to "also about her."
That's an approach that I've heard from many contemporary marital educators: in a healthy relationship, it can't be *entirely* about only one person. |

I don't know if this was an estimate of the right level of annoyance the next morning, or so that the man who did overdue it would pay a social penalty because someone would eventually notice how often he goes. This legislation was never accepted by the masses, and therefore did not become binding. (Shulchan Arukh, OC 88:1)
But the motive behind the attempt tells you something.
Similarly, Nachmanides on "qedoshim tihyu, qi Qadosh Ani -- be holy, for I Am Holy" (Vayiqra 19:2) says that the mitzvah is to avoid being a "naval bireshus haTorah -- a knave with [what would otherwise be] the permission of the Torah". Or, as Nachmanides is explained by Rav Shimon Shkop (introduction, Shaarei Yosher), to avoid those distractions from one's commitment to holiness.
What is knavely behavior? "The person who is driven by appetite (ba’al ta’avah) will find room to indulge in lustful behavior with his wife or his numerous u wives, and to be among those that swill wine and guzzle meat (per Prov 23:20), and will speak freely using all those vulgarities that are not explicitly prohibited by the Torah. ... Therefore this verse comes, after [the Torah] has enumerated those things that are completely prohibited, commanding in a general way to separate ourselves from excessive material indulgence and to restrict ourselves in sexual intercourse, as the Rabbis say, “Sages ought not to be found with their wives like roosters” [Berakhos 22a], but only engage in sexual relations according to that which is needed to fulfill the mitzvot connected therewith."
Those mitzvos being the connecting with another person "and he shall be attached to his wife and become another person" (Bereishis 2:24) and procreation (Bereishis 1:28).
Similar to Rav Shimon Shkop's take on the Ramban, that overdoing it is defined by distractions to holiness, we find Rav Moshe Chaim Luzzatto writing in Mesilas Yesharim (ch. 14) writes (bracketed insertion and emphasis mine):
>
> Separation in relation to pleasures, which we spoke of in the previous chapter [where it is given as one of three types of "separation"], consists in one’s taking from the world only what is essential to him. This type of Separation encompasses anything which provides pleasure to any one of the senses, whether the pleasure be gained through food, **cohabitation**, clothing, strolls, conversation or similar means, exceptions obtaining only at such times when deriving pleasure through these means is a mitzvah.

Just don't know how to begin. Thank you. | 2019/10/13 | ['https://math.stackexchange.com/questions/3392055', 'https://math.stackexchange.com', 'https://math.stackexchange.com/users/680628/'] | Alternatively, you could try to make use of the hyperbolic identity
$$\cosh^2t - \sinh^2t = 1 \implies \cosh^2t = 1 + \sinh^2t$$
and use the inspired substitution
$$y = x\sinh\left(f(x)\right)$$
which simplifies nicely:
$$x(\sinh(f(x)) + xf'(x)\cosh(f(x))) = |x|\cosh(f(x))+x\sinh(f(x)) \implies f'(x) = \frac{1}{|x|}$$
which implies the solution is of the form
$$y = x\sinh(\text{sgn}(x)(\log(|x|)+C)) = \frac{1}{2}(Cx^2 - C^{-1})$$
So it's an upward parabola on both sides. (the $C$'s in the final answer must be positive since they are the end result of an exponentiation). | Square both sides then replace $\sqrt{y^2+x^2}$ by $xy'-y$
This becomes
$$x^2(y')^2+y^2-xy'(1+y)-y=0$$
Now you could you appropriate subsitution |
65,788,251 | I am using reselect lib in my React project. Here is a code:
```
const App = () => {
// const { tickets, isFetching, error } = useSelector(({ tickets }) => tickets) // <- this works good
const { sorterTabs, selected } = useSelector(({ sorter }) => sorter)
const { isFetching } = useSelector(({ tickets }) => tickets)
const dispatch = useDispatch()
const tickets = useSelector(sorterSelector) // <- this doesn't work good
const handleSorterClick = ({ target }) => {
dispatch(getSelectedSorter(target.getAttribute('name')))
}
const renderedTickets = tickets.map((ticket) => { // <- problem: I have undefined here because selector returns undefined
const src = `http://pics.avs.io/99/36/${ticket.carrier}.png`
return (
<Ticket
key={ticket.price + ticket.segments[0].duration}
ticket={ticket}
price={ticket.price}
src={src}
segment={ticket.segments}
/>
)
}).slice(0,5)
useEffect(() => {
dispatch(fetchData())
}, [])
return (
<div className="container">
<Header />
<div className="content">
<Filter />
<div className="content__item">
<div className="content__item__sorting">
<Sorter
sorterTabs={sorterTabs}
selected={selected}
handleSorterClick={handleSorterClick}
/>
</div>
{isFetching
?
<img src={preloader} alt="preloader" />
:
<div className="content__item__tickets">
{renderedTickets}
</div>
}
</div>
</div>
</div>
)
}
```
Code for selector:
```
const allTickets = state => state.tickets.tickets // <- this gets undefined
const selected = state => state.sorter.selected
export const sorterSelector = createSelector(
[allTickets, selected],
(tickets, selec) => {
if (selec === "Самый дешевый") {
tickets.sort((a, b) => {
return a.price - b.price
})
} else {
tickets.sort((a, b) => {
return (a.segments[0].duration + a.segments[1].duration) - (b.segments[0].duration + b.segments[1].duration)
})
}
}
)
```
As I mentioned in the App's code, first commented line (where I destructure the object) works good: I'm fetching tickets from the server, put them in redux state, get them in App's component and render them.
But if I create selector by `createSelector` function from 'reselect' lib and put it in `useSelector` function like I mentioned in the code `const tickets = useSelector(sorterSelector)`, I got mistake: `TypeError: Cannot read property 'map' of undefined`. Tickets are not returned from the state, but state is empty. That means that `fetchData` function didn't work.
What am I doing wrong here? How to use it properly?
UPD: this doesn't work too `const tickets = useSelector((state) => sorterSelector(state))` | 2021/01/19 | ['https://Stackoverflow.com/questions/65788251', 'https://Stackoverflow.com', 'https://Stackoverflow.com/users/13115642/'] | This is a nice example of when to actually use [arrow functions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions) in favor of regular functions! Because regular functions—like in your code—establish their own `this` scope you no longer have access to the `this` scope you are interested in, namely the scope of your surroungding class.
Many D3 methods are called with `this` set to the current DOM element:
>
> with *this* as the current DOM element (*nodes*[*i*])
>
>
>
To be able to use your class instance's methods by referring to them using `this` you can just use an arrow function which does not come with its own scope but captures the scope of its surrounding context, i.e. your class/instance. Your methods should therefore look like this:
```
.attr('x', d => this.x(d.dayNumber))
``` | The `this` has a type of SVGRectElement because it is inside a regular anonymous function. In D3, methods for manipulating nodes replace the `this` context with the own DOM Element that is being manipulated, in your case a `<rect>`. The `<rect>` nodes don't have x or y methods, hence the type error.
Replacing the anonymous functions with arrow functions [preserves the `this` from the outside](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions):
```js
.attr('x', (d: HeatmapData) => {
return this.x(d.dayNumber)
})
.attr('y', (d: HeatmapData) => {
return this.y(d.timeOfDay)
})
```
Now, the `this` inside the function is the same `this` from the outside, which in your case is the class that contain svg, x, xAxis, y and yAxis. |

Thanks. | 2013/10/14 | ['https://Stackoverflow.com/questions/19363489', 'https://Stackoverflow.com', 'https://Stackoverflow.com/users/2767553/'] | Control-X is bound to the function `Control-X-prefix`, which is a keymap (a table associating keystrokes with commands).
So to set `\M-x` to work like `\C-x`, just do the following:
```
(define-key global-map "\M-x" 'Control-X-prefix)
```
All that said, instead of rebinding emacs I would recommend that you look into remapping your keyboard: Many window managers (X11, OS X and many Windows set-ups included) give you ways to customize various modifier keys (e.g., turning Left-Alt into another Control.) Look into them, you may find a set up you like. | Use `C-x C-h` to see the `C-x` bindings. Load [`help-fns+.el`](http://www.emacswiki.org/emacs/download/help-fns%2b.el) and use `C-h M-k` with `ctl-x-map` and `help-map` to see all bindings for `C-x` and `C-h`. |

Find for me the rackunit spans with NO component span.
Thus far I have:
$(".rack .rackspace") to get me all of the rackunit spans, not sure how to either exclude those with a component span or select only those without one... | 2013/01/23 | ['https://Stackoverflow.com/questions/14482707', 'https://Stackoverflow.com', 'https://Stackoverflow.com/users/681009/'] | I guess the following should work:
```
$(".rack .rackspace:not(:has(span[id^=component]))"). ...

2,915,329 | Does anyone know if there is a way to "transform" specific sections of values instead of replacing the whole value or an attribute?
For example, I've got several appSettings entries that specify the URLs for different webservices. These entries are slightly different in the dev environment than the production environment. Some are less trivial than others
```
<!-- DEV ENTRY -->
<appSettings>
<add key="serviceName1_WebsService_Url" value="http://wsServiceName1.dev.example.com/v1.2.3.4/entryPoint.asmx" />
<add key="serviceName2_WebsService_Url" value="http://ma1-lab.lab1.example.com/v1.2.3.4/entryPoint.asmx" />
</appSettings>
<!-- PROD ENTRY -->
<appSettings>
<add key="serviceName1_WebsService_Url" value="http://wsServiceName1.prod.example.com/v1.2.3.4/entryPoint.asmx" />
<add key="serviceName2_WebsService_Url" value="http://ws.ServiceName2.example.com/v1.2.3.4/entryPoint.asmx" />
</appSettings>
```
Notice that on the fist entry, the only difference is **".dev" from ".prod".** On the second entry, the subdomain is different: **"ma1-lab.lab1"** from **"ws.ServiceName2"**
So far, I know I can do something like this in the `Web.Release.Config`:
```
<add xdt:Locator="Match(key)" xdt:Transform="SetAttributes(value)" key="serviceName1_WebsService_Url" value="http://wsServiceName1.prod.example.com/v1.2.3.4/entryPoint.asmx" />
<add xdt:Locator="Match(key)" xdt:Transform="SetAttributes(value)" key="serviceName2_WebsService_Url" value="http://ws.ServiceName2.example.com/v1.2.3.4/entryPoint.asmx" />
```
However, every time the Version for that webservice is updated, I would have to update the `Web.Release.Config` as well, which defeats the purpose of simplfying my `web.config` updates.
I know I could also split that URL into different sections and update them independently, but I rather have it all in one key.
I've looked through the available `web.config` Transforms but nothings seems to be geared towars what I am trying to accomplish.
These are the websites I am using as a reference:

although you may find it easier in the long term to use implicit initialisation of your session and handle events through a delegate, as discussed here:

361,282 | During review of an article I found an erroneous sentence:
>

>
I am an engineer, with not so much knowledge in ecology. Based on my earlier studies I suggested to change *predators* to *consumers*. I checked it with a search on the net. Surprisingly I found too few hits in my search.
*Consumers of a plant* is acceptable? Can you recommend alternatives? | 2016/12/01 | ['https://english.stackexchange.com/questions/361282', 'https://english.stackexchange.com', 'https://english.stackexchange.com/users/162691/'] | According to the wikibook [Predation and Herbivory](https://en.wikibooks.org/wiki/Ecology/Predation_and_Herbivory):
>
> ecologically, predation is defined as any interaction between two organisms that results in a flow of energy between them. This definition is applicable to both plants and animals. There are four commonly recognized types of predation: (1) carnivory, (2) herbivory, (3) parasitism, and (4) mutualism.
>
>
>
So, this reference, in ecological situations, clearly accepts an animal eating a plant as a "predator" of that plant.
---
However, in more general non-technical contexts, dictionary.reference.com defines a [predator](http://www.dictionary.com/browse/predator?s=t) as (depending on which of its sources you use) either:
>
> any organism that exists by preying upon other organisms
>
>
>
or
>
> any carnivorous animal
>
>
>
The second definition would preclude its usage for eating plants. The first hinges upon the definition of "preying". Using dictionary.reference.com again, [prey](http://www.dictionary.com/browse/prey) as a verb is:
>
> to seize and devour prey
>
>
>
where that prey (as a noun) is:
>
> an animal hunted or seized for food
>
>
>
I would therefore suggest that unless you are talking to a technical ecological (or possibly biological?) crowd, **predator** would not be an appropriate term.
---
Possible terms (thanks to Hotlicks for the first one, and typing it into [thesaurus.com](http://www.thesaurus.com/browse/eater?s=t) gave the other two):
>
> **eater**: from the verb to [eat](http://www.dictionary.com/browse/eater?s=t): to take into the mouth and swallow for nourishment
>
>
> **devourer**: from the verb to [devour](http://www.dictionary.com/browse/devourer?s=t): to swallow or eat up hungrily, voraciously, or ravenously
>
>
> **[consumer](http://www.dictionary.com/browse/consumer?s=t)**: an organism, usually an animal, that feeds on plants or other animals.
>
>
> | Most of the online definitions of 'predator' such as [the ODO](https://en.oxforddictionaries.com/definition/predator), [the Cambridge](http://dictionary.cambridge.org/dictionary/english/predator) and [the Macmillan](http://www.macmillandictionary.com/dictionary/british/predator) define 'predator' as an animal which eats other animals so it would seem that to describe a herbivore as a predator of plants is not really valid.
Not only that but there is a difference between predation on animals and the majority of grazing because predation involves killing, or at least seriously and permanently injuring, the target: whereas most grazing involves eating only part of the plant which, in most cases, regenerates. Creatures like us who eat the entire root, or the whole, of some plants like potatoes and carrots are only a subset of herbivores and omnivores. |

The "is" in the translation simply corresponds to the copula です at the end of the original sentence. There is no need to change it to something else like "could be".
The "X" part consists of two nested [embedded questions](https://japanese.stackexchange.com/a/13038/5010):
>
> 【どれだけ【刃文と鉄が美しい**か**】にこだわっている**か**】
>
> 【how much [blacksmiths] are particular about 【whether their [*hamon*](https://en.wikipedia.org/wiki/Hamon_(swordsmithing)) and iron are beautiful】】
>
>

(I believe 波紋 is a misspelling and thus "ripple" is a mistranslation. The correct kanji is [刃文](https://ja.wikipedia.org/wiki/%E5%88%83%E6%96%87). That said, this misspelling is understandable because 刃文 has a wavy appearance.) | I would parse it this way:
>
> The difference between Japanese swords and other swords is this: How much do they care about "how beautiful are the ripples and iron?"?
>
>
>
And since this way there are essentially two implicit questions in this phrase it makes sense that there are two か. |
99,835 | Yesterday I heard of the [Bland-Altman plot](https://en.wikipedia.org/wiki/Bland%E2%80%93Altman_plot) for the first time. I have to compare two methods of measuring blood pressure, and I need to produce a Bland-Altman plot. I am not sure if I get everything about it right, so here's what I think I know:
I have two sets of data. I calculate their mean (x value) and their difference (y value) and plot it around the axis y = mean of difference. Then, I calculate the standard deviation of the difference, and plot it as "limits of agreement". This is what I do not understand - limits of what agreement? What means 95% agreement in layman's terms? Is that supposed to tell me (provided that all points of the scatter graph are between the "limits of agreement") that the methods have 95% match? | 2014/05/23 | ['https://stats.stackexchange.com/questions/99835', 'https://stats.stackexchange.com', 'https://stats.stackexchange.com/users/46069/'] | Have you looked at [the Wikipedia entry](https://en.wikipedia.org/wiki/Bland%E2%80%93Altman_plot) I linked in your question?
You don't plot "the mean of the data", but for each data point measured in two ways, you plot the difference in the two measurements ($y$) against the average of the two measurements ($x$). Using R and some toy data:
```r
> set.seed(1)
> measurements <- matrix(rnorm(20), ncol=2)
> measurements
[,1] [,2]
[1,] -0.6264538 1.51178117

0.2055115 0.2454398 0.8992897
> plot(xx, yy, pch=19, xlab="Average", ylab="Difference")
```
To get the limits of agreement (see under "Application" in the Wikipedia page), you calculate the mean and the standard deviation of the differences, i.e., the $y$ values, and plot horizontal lines at the mean $\pm 1.96$ standard deviations.
```r
> upper <- mean(yy) + 1.96*sd(yy)
> lower <- mean(yy) - 1.96*sd(yy)
> upper
[1] 3.141753
> lower
[1] -2.908468
> abline(h=c(upper,lower), lty=2)
```
(You can't see the upper limit of agreement because the plot only goes up to $y\approx 2.1$.)
As to the interpretation of the plot and the limits of agreement, again look to Wikipedia:
>
> If the differences within mean ± 1.96 SD are not clinically important, the two methods may be used interchangeably.
>
>
> | If you would like to do this in Python you can use this code
```py
import matplotlib.pyplot as plt
import numpy as np
from numpy.random import random
%matplotlib inline
plt.style.use('ggplot')
```
I just added the last line because I like the ggplot style.
```py
def plotblandaltman(x,y,title,sd_limit):
plt.figure(figsize=(20,8))
plt.suptitle(title, fontsize="20")
if len(x) != len(y):
raise ValueError('x does not have the same length as y')
else:
for i in range(len(x)):
a = np.asarray(x)
b = np.asarray(x)+np.asarray(y)
mean_diff = np.mean(b)
std_diff = np.std(b, axis=0)
limit_of_agreement = sd_limit * std_diff
lower = mean_diff - limit_of_agreement
upper = mean_diff + limit_of_agreement
difference = upper - lower
lowerplot = lower - (difference * 0.5)
upperplot = upper + (difference * 0.5)
plt.axhline(y=mean_diff, linestyle = "--", color = "red", label="mean diff")
plt.axhline(y=lower, linestyle = "--", color = "grey", label="-1.96 SD")
plt.axhline(y=upper, linestyle = "--", color = "grey", label="1.96 SD")
plt.text(a.max()*0.85, upper * 1.1, " 1.96 SD", color = "grey", fontsize = "14")
plt.text(a.max()*0.85, lower * 0.9, "-1.96 SD", color = "grey", fontsize = "14")
plt.text(a.max()*0.85, mean_diff * 0.85, "Mean", color = "red", fontsize = "14")
plt.ylim(lowerplot, upperplot)
plt.scatter(x=a,y=b)
```
And finaly I just make some random values and compare them in this function
```py
x = np.random.rand(100)
y = np.random.rand(100)
plotblandaltman(x,y,"Bland-altman plot",1.96)
```

[Your brain hallucinates your conscious reality | Anil Seth](https://youtu.be/lyu7v7nWzfo) |
24,514 | Basically I have created a function which takes two lists of dicts, for example:
```
oldList = [{'a':2}, {'v':2}]
newList = [{'a':4},{'c':4},{'e':5}]
```
My aim is to check for each dictionary key in the oldList and if it has the same dictionary key as in the newList update the dictionary, else append to the oldList.
So in this case the key 'a' from oldList will get updated with the value 4, also since the keys b and e from the newList don't exist in the oldList append the dictionary to the oldList. Therefore you get `[{'a': 4}, {'v': 2}, {'b': 4}, {'e': 5}]`.

Avoid boolean flags. They are delayed gotos and make it harder to follow your code. In this case, I'd suggest using an else: block on the for loop.
```
for old in oldList: #{'a':2}, {'v':2}
if new.keys()[0] == old.keys()[0]: #a == a
isAdd = False
old.update(new) # update dict
if isAdd:
oldList.append(new) #if value not in oldList append to it
return oldList
sortedDict = sortList([{'a':2}, {'v':2}],[{'a':4},{'b':4},{'e':5}])
print sortedDict
```
Why are you calling it sortList? You are merging lists, not sorting anything...
Your whole piece of code would be quicker if implemented using dicts:
```
# convert the lists into dictionaries
old_list = dict(item.items()[0] for item in oldList)
new_list = dict(item.items()[0] for item in newList)
# actually do the work (python already has a function that does it)
old_list.update(new_list)
# covert back to the list format
return [{key:value} for key, value in old_list.items()]
```
All of which raises the question: why aren't these dicts already? What are you trying to do with this list of dicts stuff? | You don't need the `isAdd` flag, instead you can structure your for loops like this:
```
for new, old in newList, oldList:
if new.keys()[0] == old.keys()[0]:
old.update(new)
else:
oldList.append(new)
return oldList
```
As well, you might want to look at [PEP](http://python.net/~goodger/projects/pycon/2007/idiomatic/handout.html) documents for coding style
For reference, here is the rest of your code with those standards in place:
```
def sort_list(old_list, new_list):
for new, old in new_list, old_list:
if new.keys()[0] == old.keys()[0]:
old.update(new)
else:
old_list.append(new)

print sorted_dict
[{'a': 4}, {'v': 2}, {'b': 4}, {'e': 5}]
```
Oh, and I'm assuming you are doing this for practice/homework, but the [dict.update(iterable)](http://docs.python.org/2/library/stdtypes.html#dict.update) method does this exact thing far, far faster than you ever could. |

d2 = {'a': 4, 'c': 4, 'e': 5}
d3 = dict(d1, **d2)
# {'a': 4, 'b': 2, 'c': 4, 'e': 5}
```
If you are going to union/merge dicts a lot, you can create a handy abstraction, more general than `dict(d1, **d2)`:
```
def merge_dicts(d1, d2):
return dict(itertools.chain(d1.items(), d2.items()))
```
To convert list of dictionaries to a dictionary is simple:
```
d2 = dict(list(d.items())[0] for d in new_list)
# {'a': 4, 'c': 4, 'e': 5}
``` | You don't need the `isAdd` flag, instead you can structure your for loops like this:
```
for new, old in newList, oldList:
if new.keys()[0] == old.keys()[0]:
old.update(new)
else:
oldList.append(new)
return oldList
```
As well, you might want to look at [PEP](http://python.net/~goodger/projects/pycon/2007/idiomatic/handout.html) documents for coding style
For reference, here is the rest of your code with those standards in place:
```
def sort_list(old_list, new_list):
for new, old in new_list, old_list:
if new.keys()[0] == old.keys()[0]:
old.update(new)
else:
old_list.append(new)
return old_list
sorted_dict = sort_list([{'a':2}, {'v':2}],[{'a':4},{'b':4},{'e':5}])
print sorted_dict
[{'a': 4}, {'v': 2}, {'b': 4}, {'e': 5}]
```
Oh, and I'm assuming you are doing this for practice/homework, but the [dict.update(iterable)](http://docs.python.org/2/library/stdtypes.html#dict.update) method does this exact thing far, far faster than you ever could. |
24,514 | Basically I have created a function which takes two lists of dicts, for example:
```
oldList = [{'a':2}, {'v':2}]
newList = [{'a':4},{'c':4},{'e':5}]
```
My aim is to check for each dictionary key in the oldList and if it has the same dictionary key as in the newList update the dictionary, else append to the oldList.
So in this case the key 'a' from oldList will get updated with the value 4, also since the keys b and e from the newList don't exist in the oldList append the dictionary to the oldList. Therefore you get `[{'a': 4}, {'v': 2}, {'b': 4}, {'e': 5}]`.
Is there a better way to do this?
```
def sortList(oldList, newList):
for new in newList: #{'a':4},{'c':4},{'e':5}
isAdd = True
for old in oldList: #{'a':2}, {'v':2}
if new.keys()[0] == old.keys()[0]: #a == a
isAdd = False
old.update(new) # update dict
if isAdd:
oldList.append(new) #if value not in oldList append to it
return oldList
sortedDict = sortList([{'a':2}, {'v':2}],[{'a':4},{'b':4},{'e':5}])
print sortedDict
[{'a': 4}, {'v': 2}, {'b': 4}, {'e': 5}]
``` | 2013/03/29 | ['https://codereview.stackexchange.com/questions/24514', 'https://codereview.stackexchange.com', 'https://codereview.stackexchange.com/users/23629/'] | A list of 1-pair dictionaries makes no sense as data structure. You should join them to create a single dictionary. This way all your code reduces to:
```
d1 = {'a': 2, 'b': 2}
d2 = {'a': 4, 'c': 4, 'e': 5}
d3 = dict(d1, **d2)
# {'a': 4, 'b': 2, 'c': 4, 'e': 5}
```
If you are going to union/merge dicts a lot, you can create a handy abstraction, more general than `dict(d1, **d2)`:
```
def merge_dicts(d1, d2):
return dict(itertools.chain(d1.items(), d2.items()))
```
To convert list of dictionaries to a dictionary is simple:
```
d2 = dict(list(d.items())[0] for d in new_list)
# {'a': 4, 'c': 4, 'e': 5}
``` | ```
def sortList(oldList, newList):
```
Python convention is to lowercase\_with\_underscores for pretty much everything besides class names
```
for new in newList: #{'a':4},{'c':4},{'e':5}
isAdd = True
```
Avoid boolean flags. They are delayed gotos and make it harder to follow your code. In this case, I'd suggest using an else: block on the for loop.
```
for old in oldList: #{'a':2}, {'v':2}
if new.keys()[0] == old.keys()[0]: #a == a
isAdd = False
old.update(new) # update dict
if isAdd:
oldList.append(new) #if value not in oldList append to it
return oldList
sortedDict = sortList([{'a':2}, {'v':2}],[{'a':4},{'b':4},{'e':5}])
print sortedDict
```
Why are you calling it sortList? You are merging lists, not sorting anything...
Your whole piece of code would be quicker if implemented using dicts:
```
# convert the lists into dictionaries
old_list = dict(item.items()[0] for item in oldList)
new_list = dict(item.items()[0] for item in newList)
# actually do the work (python already has a function that does it)
old_list.update(new_list)
# covert back to the list format
return [{key:value} for key, value in old_list.items()]
```
All of which raises the question: why aren't these dicts already? What are you trying to do with this list of dicts stuff? |
74,616,016 | How do I add a string/integer into an existing text file at a specific location?
My sample text looks like below:
```txt
No, Color, Height, age
1, blue,70,
2, white,65,
3, brown,49,
4, purple,71,
5, grey,60,
```
My text file has 4 columns, three columns have text, how do I write to any row in the fourth column?
If I want to write 12 to the second row, the updated file (sample.txt) should look like this:
```txt
No, Color, Height, age
1, blue,70,12
2, white,65,
3, brown,49,
4, purple,71,

with open("sample.txt",'r') as file:
data =file.readlines()
data[1]. split(",") [3] = 1
with open ('sample.txt', 'w') as file:
file.writelines(data)
with open ('sample.txt', 'r') as file:
print (file. Read())

But it does not work. Your help is needed. | 2022/11/29 | ['https://Stackoverflow.com/questions/74616016', 'https://Stackoverflow.com', 'https://Stackoverflow.com/users/5255512/'] | Here's the proper `case_when` syntax.
```
df <- data.frame(x = c("A", "B", "C", "D"))
library(dplyr)
df <- df %>%
mutate(y = case_when(x %in% c("A", "D") ~ 1,
x %in% c("B", "C") ~ 0,
TRUE ~ NA_real_))
df
#> x y
#> 1 A 1
#> 2 B 0
#> 3 C 0
#> 4 D 1
``` | You're combining syntaxes in a way that makes sense in speech but not in code.
Generally you can't use `foo == "G" | "H"`. You need to use `foo == "G" | foo == "H"`, or the handy shorthand `foo %in% c("G", "H")`.
Similarly `x %in% df == "A"` doesn't make sense `x %in% df` makes sense. `df == "A"` makes sense. Putting them together `x %in% df == ...` does not make sense to R. (Okay, it does make sense to R, but not the same sense it does to you. R will use its Order of Operations which evaluates `x %in% df` first and gets a `result` from that, and then checks whether that `result == "A"`, which is not what you want.)
Inside a `dplyr` function like `mutate`, you don't need to keep specifying `df`. You pipe in `df` and now you just need to use the column `x`. `x %in% df` looks like you're testing whether the column `x` is in the data frame `df`, which you don't need to do. Instead use `x %in% c("A", "D")`. Aron's answer shows the full correct syntax, I hope this answer helps you understand why. |

64,814,676 | I have a simple HTMLAudioElement element:
```
let player = new Audio()
player.src = 'file://' + _filePath
player.load()
```
This pauses and plays by using the play/pause media keys while the windows isn't focused,
**Q:** how do I make it ignore the play/pause keys?
I'm using electron but not sure if this is a chrome or electron implementation so I'm tagging both. | 2020/11/13 | ['https://Stackoverflow.com/questions/64814676', 'https://Stackoverflow.com', 'https://Stackoverflow.com/users/5905035/'] | Found an answer in this question: [Disable media control keys with javascript](https://stackoverflow.com/questions/59347480/disable-media-control-keys-with-javascript), thanks @PableWeb18
We can just override the media key listeners:
```
navigator.mediaSession.setActionHandler('play', function() { /* Code excerpted. */ });
navigator.mediaSession.setActionHandler('pause', function() { /* Code excerpted. */ });
navigator.mediaSession.setActionHandler('seekbackward', function() { /* Code excerpted. */ });
navigator.mediaSession.setActionHandler('seekforward', function() { /* Code excerpted. */ });
navigator.mediaSession.setActionHandler('previoustrack', function() { /* Code excerpted. */ });
navigator.mediaSession.setActionHandler('nexttrack', function() { /* Code excerpted. */ });
``` | To override a function you can use `prototype`, see the example below:
```js
var audio = new Audio();
Audio.prototype.play = function() {
console.log('Play override')
};
Audio.prototype.stop = function() {
console.log('Stop override')
};
audio.play();
audio.stop();
```
`EDIT:`
So just add the primary function inside a var and after you done, put in together using prototype again:
```js
var audio = new Audio('https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3');
var play = audio.play;
var pause = audio.pause;
Audio.prototype.play = function() {
console.log('Nothing happened')
};
Audio.prototype.pause = function() {
console.log('Nothing happened')
};
audio.play();
audio.pause();
Audio.prototype.play = play;
Audio.prototype.pause = pause;
audio.play();
setTimeout(function() { audio.pause() }, 5000)

Why doesn't it remove the String at `list.get(i)` and `list.get(i-1)`? | 2016/03/14 | ['https://Stackoverflow.com/questions/35996096', 'https://Stackoverflow.com', 'https://Stackoverflow.com/users/5938067/'] | There is no need for sorting.
A better approach would be to use two HashSet One for maintaining repeating and one for non-repeating words. Since HashSet internally uses HashMap, Ideally contains, get, put operation has o(1) complexity. So the overall complexity of this approach would be o(n).
```
public static int countNonRepeats(List<String> words) {
Set<String> nonRepeating = new HashSet<String>();
Set<String> repeating = new HashSet<String>();
for (String i : words) {
if(!repeating.contains(i)) {
if(nonRepeating.contains(i)){
repeating.add(i);
nonRepeating.remove(i);
}else {
nonRepeating.add(i);
}
}
}
System.out.println(nonRepeating.size());
return nonRepeating.size();
}
``` | You can use hashmap to achieve this.With this approach we can count the occurrence of all the words,
If we are interested in only unique words then access the element having count = 1.
**`HashMap<String,Integer>`** - key represents the String from arraylist and Integer represents the count of occurrence.
```
ArrayList<String> list = new ArrayList<String>();
HashMap<String, Integer> hashMap = new HashMap<String, Integer>();
for (int i = 0; i < list.size(); i++) {
String key = list.get(i);
if (hashMap.get(key) != null) {
int value = hashMap.get(key);
value++;
hashMap.put(key, value);
} else {
hashMap.put(key, 1);
}
}
int uniqueCount = 0;
Iterator it = hashMap.entrySet().iterator();
while (it.hasNext()) {
Map.Entry pair = (Map.Entry) it.next();
if ((int) pair.getValue() == 1)
uniqueCount++;
}
System.out.println(uniqueCount);

317,552 | I'm trying to export a layer via QTiles, gotten from the Data Source Manager and connecting to ([USGSHydroCached](https://basemap.nationalmap.gov/arcgis/rest/services/USGSHydroCached/MapServer)).
I have QTiles set to zoom levels `0-20` and `Render tiles outside of layers extent` checked (basemap goes up to `20`). For some reason, the hydro layer only shows up to zoom level `17` (as per Leaflet). At zoom levels `18,19,20` the layer disappears.
QTiles is generating folders and files up to zoom level `20` (assuming this is the extent checkbox).
Is there a way to have it render the tile beyond that zoom level (poor resolution is fine)? | 2019/04/02 | ['https://gis.stackexchange.com/questions/317552', 'https://gis.stackexchange.com', 'https://gis.stackexchange.com/users/139763/'] | The layer info at the link you provide indicates the MapServer should provide tiles up to level 19, not 20 as you'd like. But that shouldn't create problems at level 17!
However, I've played around with zooming in on the layer the QGis map window and it shows up at scales up to 1:6019, but not more detailed than that. So there's something funny with the tiles being returned by the server at levels 17+. QTiles is a red herring here, it's just that's what's asking for the layer at detailed scales.
Since it's actually a simple line layer, it would be much better if you could find a vector (rather than tile/raster) source for it. I tried a trick that often works, to try to connect to it as an ArcGisFeatureServer rather than MapServer, replacing MapServer with FeatureServer in the URI, but that didn't work. Your ideal solution would be to hunt and see a FeatureServer or WFS source for it.
Failing that, you can get a jagged version by exporting it in the region of interest at a scale that works, and then loading that into your map instead. To do that, load it in, zoom into a generous area well beyond your area of interest, right click on the layer in the layer tree and choose Export / Save as...
Then do the following; note VRT is off, click on Map Canvas Extent to set the region that will be exported, and the resolution 2.388657133974685 is chosen since that's the resolution of a Level 16 tile that works. Then use your saved .tif rather than the MapServer version.
[](https://i.stack.imgur.com/swbnR.png)
If you want to get fancy, keep both layers, but make them visible at different scales via layer properties.
And/or vectorize the raster you saved, and then style it to your heart's content (color, line thickness etc) that will then render properly at any scale level (just of course with the level of underlying detail you exported, no more no less). | As @Houska has noted the map service that you are using only provides tiles down to level 17. However, the data supplied in the map service is the [USGS National Hydrography Dataset](https://www.usgs.gov/core-science-systems/ngp/national-hydrography/access-national-hydrography-products) which is freely available to download in vector form, so if you want to generate tiles at any zoom level, this can be done by using a styled version of the vector NHD data. |
28,175 | After some research surrounding this I can't seem to fix this issue. So for a project I made a simple module with some variables that simply has to make an OAuth1 call and return some data.
The provider of the website advised me to use :
<https://github.com/thephpleague/oauth1-client>
So in my module I initialised another composer.json and required the package above. It gets correctly installed to the vendor map in my module. However whenever I call the new OAuth() or new OAuth1() it can't be found.
I've tried adding it while using the packagepath in the top of my module.php as well as my moduleVariable.php but to no avail. I was wondering if I'm doing something wrong? Or forgetting something? What's the best way to add composer libraries to your own custom module?

In addition, you can be more explicit about the values you’re searching for (and avoid any kind of sneaky `search` capabilities/side-effects exposed by using raw query input):
```
{% set location = block.locationVacancies %}
{% set entries = craft
.entries
.section('careers')
.locationVacancies("*#{location}*")
.all() %}

…or even using Twig object syntax…
```
{% set location = block.locationVacancies %}
{% set entries = craft.entries({
section: 'careers',
locationVacancies: "*#{location}*"
}).all() %}

(`locationVacancies: location` will also work, but disables partial matching)

> It should be noted: if you're looking to associate multiple explicit entries, you can also make the field within your (presumed) Matrix Block an `Entries` field, which establishes actual relationships in the database—accessing such a field (`myBlock.myLocationEntriesField.all()`) will return that list of Entries, exactly as set in the admin) If you just need a dynamic search param, what you have is a fine solution!

Say we have two selects.

`<select id="endTime">
<option value="na">Please Select A Time</option>
<option value=1>1:00PM</option>
</select>`
We start by setting the end time hidden
`$('#endTime').css('display', 'none');`
Then we register an event handler. Everytime it is changed, we look at the value to see if it different from our default placeholder.
```
$('#startTime').change(function () {
if($('#startTime').val() !== 'na') {
$('#endTime').css('display', 'initial');
}
});
```
If it is, we set endTime back to its initial display state.
`$('#endTime').css('display', 'initial');` |

The only reason I think that could happen is if `mActivity == null` at `GameHelper.java:752`:
```java
mConnectionResult.startResolutionForResult(mActivity, RC_RESOLVE);
```
`mActivity` gets null on `onStop()`
Is it possible that GameHelper.java has bug and can crash if `onConnectionFailed()` happens after `onStop()` is called?
Thanks.
EDITED:
It happened after update to the latest Play API (rev 15) together with the updated GameHelper.java. | 2014/02/25 | ['https://Stackoverflow.com/questions/22018987', 'https://Stackoverflow.com', 'https://Stackoverflow.com/users/1986565/'] | EDIT:
This now has been fixed in latest GameHelper version:
<https://github.com/playgameservices/android-samples/commit/e7b3758c136b5b434f1dfd9ca8c03f75aad70f09>
OLD ANSWER:
For me it happens on the start of the app, when Google Play Services asks me to sign in and if I click cancel, this same error happens.
So when leaving from your own activity to sign in activity, it dispatches onStop event, and fails to connect because of the user initiated process, which is resolvable, thus the error happens.
So my quick hack was changing:
```
catch (SendIntentException e)
```
to simply
```
catch (Exception e)
```
So it would also catch Null pointer exception
Of course in this case the signup process might not proceed, so I initate relogin on another action and it seems to work for now.
More thorough hack could be trying to resolve the result on activity start, for that we define pending resolution variable:
```
// Are we expecting the result of a resolution flow?
boolean mExpectingResolution = false;
boolean mPendingResolution = false;
```
Then on the error line we check if activity is not null
```
if(mActivity != null)
mConnectionResult.startResolutionForResult(mActivity, RC_RESOLVE);
else
mPendingResolution = true;
```
And on start we check and try to resolve it:
```
if(mPendingResolution && mConnectionResult != null)
try {
mConnectionResult.startResolutionForResult(mActivity, RC_RESOLVE);
} catch (SendIntentException e) {
e.printStackTrace();
}
```
This should help until the official resolution from lib supporters :) | Today is 16th september 2014 and I still facing this problem.
I don't know why anyone else did not answer about to comment GameHelper line.
In onStop method there is a line to set mActivity variable as null.
I commented this line (like below) and my app is working properly.
```
/** Call this method from your Activity's onStop(). */
public void onStop() {
debugLog("onStop");
assertConfigured("onStop");
if (mGoogleApiClient.isConnected()) {
debugLog("Disconnecting client due to onStop");
mGoogleApiClient.disconnect();
} else {
debugLog("Client already disconnected when we got onStop.");
}
mConnecting = false;
mExpectingResolution = false;
// let go of the Activity reference
//mActivity = null; //COMMENT THIS LINE!!!!
//COMMENT ABOVE LINE
}
```

However, I'm still struggling. My laptop is Dell XPS15. Its display is 3840x2160. I have tried different external monitors, but at the moment the one I use is also Dell with resolution 1920x1080.
When I connect external monitor, some of the panels immediately become very small on 3840x2160 screen. When I try to scale up build-in display, chrome scales, my IDE scales, but displays window along with other windows like NVIDIA X Server settings stay very small. I have tried to play with **Scale all window contents to match** in **Display** but to no avail. It's either too big on the external screen or to small on the build-in.
I have also tried xrandr with scale param but it gives me:
```
xrandr --output HDMI-1 --scale 2x2
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 26 (RRSetCrtcTransform)
Value in failed request: 0x40
Serial number of failed request: 38
Current serial number in output stream: 39
```
**Ideally, I want several windows of the same application(let's say Chrome or Intellij Idea to be open on different displays and scale independently on them).**
### EDIT
I am not looking for **Scale for menus and title bar**, I like the way the bars are. I want windows contents scaled independently. **Displays** UI forces me to either scale all windows to match Built-id display or the external display. As a result:
1. *Scale all window contents to match* Build-In Display:
Build-In Display - everything looks perfect;
External Display - everything is huge.
2. *Scale all window contents to match* External Display:
Build-In Display - very small;

* I wrote [this answer](https://askubuntu.com/a/727897/26246) before, that may introduce some debugging tools like `xtrace`
* Avoid running multiple/sequential `xrandr` commands, only after X server reset. Same command may have different result depending on previous commands.

Method 2: `nvidia-settings` View Port In/Out
--------------------------------------------
*Note, doesn't work well. `nvidia-settings` does not change frame-buffer to the required size as in `xrandr` command.* It seems a bug (kind of, `nvidia` has its own FB), need more research.
Tried to replicate `xrandr` setup directly using `nvidia-settings` (I used xrandr from method1, marked down nvidia setting, reset settings, then used nvidia-settings directly):
1. `gksu nvidia-settings` → X Server Display Configuration
2. Select external monitor → advanced...
3. Make *ViewPortIn* & *Panning* double of *ViewPortOut* (which is the same as original resolution)
4. Leave internal monitor unchanged then *Apply*
Example:
* [Internal monitor nvidia settings](https://i.stack.imgur.com/CtJeC.png)

Position: +0+0
ViewPortIn: 1280x800

14,074,731 | Is it valid HTML to use IRIs containing non-ASCII characters as attribute values (e.g. for `href` attributes) instead of URIs? Are there any differences among the HTML flavors (HTML and XHTML, 4 and 5)? At least [RFC 3986](https://www.rfc-editor.org/rfc/rfc3986#page-16) seems to imply that it isn't.
I realize that it would probably be safer (regarding older and IRI-unaware software) to use percent encoding, but I'm looking for a definitive answer with regards to the standard.
So far, I've done some tests with the [W3C validator](http://validator.w3.org/), and unescaped unicode characters in URIs don't trigger any warnings or errors with HTML 4/5 and XHTML 4/5 doctypes (but of course the absence of error messages doesn't imply the absence of errors).
At least chrome also supports raw UTF-8 IRIs, but percent-escapes them before firing an HTTP request. Also, my web server (lighttpd) seems to support UTF-8 characters in their percent-encoded as well as in unencoded form in an HTTP request. | 2012/12/28 | ['https://Stackoverflow.com/questions/14074731', 'https://Stackoverflow.com', 'https://Stackoverflow.com/users/1016939/'] | HTML 4.01 is straightforward enough.

>
> ... the following href value is illegal:

>
> `<A href="http://foo.org/Håkon">...</A>`

HTML5 is different. It says [IRIs are valid providing they comply with some additional conditions.](http://www.w3.org/html/wg/drafts/html/CR/infrastructure.html#valid-url)

XHTML 1.x follows the same rules as HTML 4.01.
XHTML5 is the same as HTML5. | When in doubt, read the official HTML specs for definitive answers.
HTML 4 does not support IRIs at all. They must be encoded as URIs per [RFC 3987 Section 3.1](https://www.rfc-editor.org/rfc/rfc3987#section-3.1), or encode non-ASCII URI data as UTF-8 with percent encoding per [HTML4 Section B.2.1](http://www.w3.org/TR/html4/appendix/notes.html#non-ascii-chars)
HTML 5 supports both URIs and IRIs in all places where URLs are allowed, per [HTML5 Section 2.6](http://www.w3.org/html/wg/drafts/html/CR/infrastructure.html#urls). |
3,428,999 | Prove $\sin(\sqrt x)$ is not periodic.
My wrong assumption was non-periodicity is due to the injectivity of the square root, but, then this would work for any positive real number, but it doesn't, and $\sin(x^2)$ isn't periodic either, so injectivity fails.
I find this example more interesting because it is defined on the interval $[0,+\infty)$ so it can't be periodic on the interval $(-\infty,0).$
On the other hand, $\;\sin\left(\sqrt{x}\right)\;=\sin\left(\sqrt{x+\tau}\right)$ seems hopeless.
How does composition behave in general when talking about periodicity?

$\sin\left(\sqrt{2}x\right),$

The zeroes of this function are $$x=0, x= \pi ^2, x=4\pi ^2, x=9\pi ^2,....$$

For a periodic function we have to have $f(x+P)=f(x)$ for some period $P$ so if you get $ f(x)=0$ , you have to have $$f(x+P)=f(x+2P)=... =0$$

$$g(u+U)=g(u)+kT$$ for some integer constant $k$.
Now if
$$h(u):=g(u)-kT\frac uU,$$
$$h(u+U)=g(u+U)-kT\frac{u+U}U=g(u)+kT-kT\frac{u+U}U=h(u)$$ and $h$ is periodic.
Finally, $g$ must be of the form
$$g(u)=kT\frac uU+h(u)$$ where $h$ is periodic of period $U$.
---
E.g. let $f(x)=\{x\}$, which is periodic with period $1$ and let us choose $h(x)=\sin(x)$ (period $2\pi$). We also choose $k=2$ and get
$$g(x)=\frac x\pi+\sin(x).$$

``` | If you want receive data from the your module field (`textarea` in system config), you could use next solution:

public function getRestrictedZipCodes()
{
// Replace 'test/module/zips' with the original path from the system.xml file
$restrictedCodesString = Mage::getStoreConfig('test/module/zips');
$restrictedCodesString = preg_replace('/\s+/', '', $restrictedCodesString);

```
public function collectRates(Mage_Shipping_Model_Rate_Request $request)
{
$postCode = $request->getDestPostcode();
$restrictedCodes = $this->getRestrictedZipCodes(); //changes
if (!in_array($postCode, $restrictedCodes)) {
return false;
}
// other code.....
```
Test field:
[](https://i.stack.imgur.com/aqBR1.png)
Result:
[](https://i.stack.imgur.com/12vRZ.png)
If you want get your zip codes anywhere you can always use `getRestrictedZipCodes()` method.
You can find path to the field in the *system.xml* file of your module (in the *etc* directory)
If you want to transfer your zip code values elsewhere in the database, you will need to create a separate collection and source model for your zip codes. |

If you want to transfer your zip code values elsewhere in the database, you will need to create a separate collection and source model for your zip codes. | create an extension what will provide a section in system configuration(You can create this by silk module creator). and corresponding messages. and create an Ajax for front-end check. and fetch data from that system->configuration part and do your checking part. enjoy.. :) |

```

14,863,806 | Well I've did do my research and I just can't seem to figure this out. So long story short, I'm using something like this:
btw, "(WebsiteInfo)" is just to sensor out my website/database information.
```
$SQL = new PDO('mysql:dbname=(WebsiteInfo);host=(WebsiteInfo);charset=utf8', '(WebsiteInfo)', '(WebsiteInfo)');
$SQL -> setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$SQL -> setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
```
Now, that's just currently just to start the database connect up. Which btw is mostly just a copy/paste code I found on this website too which is to prevent MySQL injection. Actually from this link [How can I prevent SQL injection in PHP?](https://stackoverflow.com/questions/60174/how-to-prevent-sql-injection-in-php). If there's anything wrong with it, I wouldn't mind advice or tips. As long as if it makes sense because I just started using databases probably not even a week ago so everything is new to me. Now there's this:
```
$Exicu = $SQL -> prepare("SELECT `tags` FROM `users` WHERE `user_id` = :a ") -> execute(array( ':a' => 16));
```
`$Exicu` is just there, because I have been trying to get the results from the query (if I said that right). Also the 16 is the users ID, but this will change often so that's why 16 isn't just tossed in the prepare statement. I've tried a lot of things but none of them worked. It either didn't work or made the PHP crash.
But anyway, things I already tried for `$Exicu` is `$Exicu->rowCount()`, `$Exicu->bindParam`, a while loop with `$row = $Exicu->fetch()`, `$SQL->query($Exicu)->fetchAll();`, a `foreach` loop with `($Exicu->fetch(PDO::FETCH_ASSOC) as $row)`, `$Exicu->get_result()`, `echo PDO::query($Exicu);`, `echo mysql_result($Exicu)`, and just `echo $Exicu`. Yes I know, that looks pretty sloppy.
But none of these seemed to work to just show me the `tags` from the database of the specific user. So that's pretty much what I need help with. There's no problem when I use something like this `echo mysql_result( mysql_query("SELECT (etc,etc)") )` but that doesn't have protection from MySQL injections. | 2013/02/13 | ['https://Stackoverflow.com/questions/14863806', 'https://Stackoverflow.com', 'https://Stackoverflow.com/users/1733856/'] | I do my PDO queries like this:
```
$user_id = 16;
$query = $SQL->prepare('SELECT tags FROM users WHERE user_id = :uid');
$query->bindValue(':uid', $user_id, PDO::PARAM_INT);
$query->execute();
while ($row = $query->fetch(PDO::FETCH_ASSOC))
{
echo $row['tags'];
}
```
This will select data from the database, bind values in it safely and then we echo out the results.
The loop is needed to iterate through every result returned from the query. You can skip the looping part and create a variable like in the `while` statement, and use `$row` as an array with your results. | There is a thing called *user defined function*.
I am wondering why noone on this site ever using them.
For some reason everyone is ready to make a mile long single line of chained methods, instead of clean and concise function call:
```
$user_id = 16;
$tags = getone('SELECT tags FROM users WHERE user_id = ?',array($user_id));
```
there are many ways to create such a function. A quick and dirty one
```
function getone($sql, $data) {
global $SQL;
$stmt = $SQL->prepare($sql);
$stmt->execute($data);
return reset($stmt->fetch());
}
```
but of course it would be better to make set of functions and put them in a class |
50,848 | This is my first question on here so I hope I'm not breaking any rules, but I have a problem:
I have a site that uses an Adobe Site Catalyst for its online analytics. The suite supports tagging through JavaScript and when implemented, it looks something like this that is placed on `http://www.mydomain.com`:
```
<script language="JavaScript" type="text/javascript">
s.channel="/my-tracking-tag/"
</script>`
```
The problem is that Google is reading this JavaScript and interpreting the `s.channel` string as a relative location on my website and is crawling it. I then get a 404 error in Google Webmaster Tools saying that the URL `http://www.mydomain.com/my-tracking-tag/` does not exist, and that it was linked to by the URL that the JavaScript tag code was on.
Is there any to avoid this behavior? I thought about adding URL with a 404 error to my *robots.txt* file but tracking campaigns are constantly updating and it would be burdensome to update the text file with the constantly updating tags. I also though about structuring the string in `s.channel` as something like `'s.channel= "/" + "my-tracking-tag" + "/"` but I'm not sure if that would due the trick, and would also require implementation guidelines to be developed for the future. | 2013/07/16 | ['https://webmasters.stackexchange.com/questions/50848', 'https://webmasters.stackexchange.com', 'https://webmasters.stackexchange.com/users/-1/'] | I've encountered this as well. It's annoying that Google is reporting 404 errors on something you never actually link to, but only based on their heuristic that finds links in JavaScript code.
These reported errors don't seem to indicate actual problems than need to be addressed. [Google's John Mueller posted this on Google+](https://johnmu.com/painful-crawl-errors/):
>
> 1. **404 errors on invalid URLs do not harm your site’s indexing or ranking in any way.** It doesn’t matter if there are 100 or 10 million, they won’t harm your site’s ranking. <http://googlewebmastercentral.blogspot.ch/2011/05/do-404s-hurt-my-site.html>
> 2. In some cases, crawl errors may come from a legitimate structural issue within your website or CMS. How you tell? Double-check the origin of the crawl error. If there's a broken link on your site, in your page's static HTML, then that's always worth fixing. (thanks [Martino Mosna](https://plus.google.com/114158417244913509295/posts))
> 3. What about the funky URLs that are “clearly broken?” When our algorithms like your site, they may try to find more great content on it, for example by trying to discover new URLs in JavaScript. If we try those “URLs” and find a 404, that’s great and expected. We just don’t want to miss anything important (insert overly-attached Googlebot meme here). <http://support.google.com/webmasters/bin/answer.py?answer=1154698>
> 4. You don’t need to fix crawl errors in Webmaster Tools. The “mark as fixed” feature is only to help you, if you want to keep track of your progress there; it does not change anything in our web-search pipeline, so feel free to ignore it if you don’t need it.
> <http://support.google.com/webmasters/bin/answer.py?answer=2467403>
> 5. We list crawl errors in Webmaster Tools by priority, which is based on several factors. If the first page of crawl errors is clearly irrelevant, you probably won’t find important crawl errors on further pages.
> <http://googlewebmastercentral.blogspot.ch/2012/03/crawl-errors-next-generation.html>
> 6. There’s no need to “fix” crawl errors on your website. Finding 404’s is normal and expected of a healthy, well-configured website. If you have an equivalent new URL, then redirecting to it is a good practice. Otherwise, you should not create fake content, you should not redirect to your homepage, you shouldn’t robots.txt disallow those URLs -- all of these things make it harder for us to recognize your site’s structure and process it properly. We call these “soft 404” errors.
> <http://support.google.com/webmasters/bin/answer.py?answer=181708>
> 7. Obviously - if these crawl errors are showing up for URLs that you care about, perhaps URLs in your Sitemap file, then that’s something you should take action on immediately. If Googlebot can’t crawl your important URLs, then they may get dropped from our search results, and users might not be able to access them either.
