The author of the library should fix it, but meanwhile you can:
1. Delete the existing `node_modules` folder
2. `npm install miller-rabin@1.1.1 --save-peer`
3. `npm install browserify` | Try zipping your existing node\_modules and package.json, then delete them.
You may need to 1st generate a new package.json using:

npm init

```
npm install browserify -g

[Error listing](https://github.com/substack/node-browserify/issues/1049)
To summarise the solution posted in the issue, you need to install miller-rabin@1.1.1 as a peer-dependency in your own project (npm install miller-rabin@1.1.1 --save-peer) that makes sure the bn.js@0.15 is used rather than the more recent version.

[Error listing](https://github.com/substack/node-browserify/issues/1049)
To summarise the solution posted in the issue, you need to install miller-rabin@1.1.1 as a peer-dependency in your own project (npm install miller-rabin@1.1.1 --save-peer) that makes sure the bn.js@0.15 is used rather than the more recent version.

The author of the library should fix it, but meanwhile you can:

To summarise the solution posted in the issue, you need to install miller-rabin@1.1.1 as a peer-dependency in your own project (npm install miller-rabin@1.1.1 --save-peer) that makes sure the bn.js@0.15 is used rather than the more recent version.

] | Recently found this issue on browserify's github.
<https://github.com/substack/node-browserify/issues/1049>
There is a workaround described. | Try zipping your existing node\_modules and package.json, then delete them.
You may need to 1st generate a new package.json using:
```
npm init
```
Then install browserify locally:
`npm install browserify`
Also, you'll have to install browserify globally:
```
npm install browserify -g
```
To zip on CMD or terminal refer to the following article:
[How to zip a file using cmd line?](https://stackoverflow.com/questions/18180060/how-to-zip-a-file-using-cmd-line) |
25,648,704 | I am getting trouble trying to delete a pointer that is owned by a vector. In my application I have a QListView, and I store new items based on a vector of pointers. This is the declaration:
```
private:
vector<QStandardItem *> item;
QStandardItemModel* model = new QStandardItemModel();
```
I simplified it, but it is an attribute of a class. To add new items I use this code:
```
this->item.push_back(new QStandardItem());
for (unsigned long i = 0; i != this->item.size(); ++i) {
this->item[i]->setCheckable( true );
this->item[i]->setCheckState( Qt::Checked );
this->item[i]->setText( "Current " + QString::number(i) );
this->model->setItem( i, this->item[i] );
ui->listView->setModel( model );
}
```
This works just fine. Now I am trying to add a delete button which deletes the current index on the QListView. This is the code I made so far:
```
QModelIndex index = ui->listView->currentIndex();
int deleteIndex = index.row();
this->model->removeRow(deleteIndex);
delete this->item[deleteIndex];
this->item.erase(this->item.begin() + deleteIndex);
```
For what I searched on StackOverflow, the line
```
delete this->item[deleteIndex];
```
should work, but I am getting an application crash every time I press the delete button. Without that line the button works fine, the problem is that I am not deallocating the memory used by that item.
EDIT: I already made a question related to the same problem.
[[Error using Qt and unique pointers](https://stackoverflow.com/questions/25631923/error-using-qt-and-unique-pointers][1])
Now I am wondering if I am trying to delete the pointer two times, and thats why I am getting the error. The problem is that my knowledge about c++ and qt is not very high. | 2014/09/03 | [

] | You're actually deleting a second time the `QStandardItem` that was at this index. Indeed, as you can see in the following extract from the Qt doc of the [`QStandardItemModel`'s function `setItem`](http://qt-project.org/doc/qt-5/qstandarditemmodel.html#setItem)
>
> Sets the item for the given row and column to item. **The model takes ownership of the item**. If necessary, the row count and column count are increased to fit the item. **The previous item at the given location (if there was one) is deleted.**
>
>
>
the `QStandardItemModel` manages any `QStandardItem` you would pass it, and thus you should never try to delete these.
As a rule of thumb, when you're unsure, check the Qt documentation for any function where you pass a `QObject`. If it says it take ownership, then never delete it. | As far as I know, Qt is managing the lifetime of the objects through a parent-child relationship and automatically deletes children. This was at least the case Qt while I was using it. Considering that, I think there is no need for manual memory management here because the item will be deleted by Qt. |

] | I wrote a [blog post](http://www.joshclarkson.net/blog/file-uploads-in-a-hidden-iframe-using-jquery/) about doing this with jQuery to upload a file using a hidden iframe. Here's the code:
Here is the HTML for the form:
```
<div id="uploadform">
<form id="theuploadform">
<input type="hidden" id="max" name="MAX_FILE_SIZE" value="5000000" >
<input id="userfile" name="userfile" size="50" type="file">
<input id="formsubmit" type="submit" value="Send File" >
</form>
```
The DIV in which to allow jQuery to create the iframe you can hide it with a little CSS:
```
<div id="iframe" style="width:0px height:0px visibility:none">
</div>
```
The DIV in which to show the results of the callback:
```
<div id="textarea">
</div>
```
The jQuery code:
```
<script type="text/javascript" src="js/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#formsubmit").click(function() {
var userFile = $('form#userfile').val();
var max = $('form#max').val();
var iframe = $( '<iframe name="postframe" id="postframe" class="hidden" src="about:none" />' );
$('div#iframe').append( iframe );
$('#theuploadform').attr( "action", "uploader.php" )
$('#theuploadform').attr( "method", "post" )
$('#theuploadform').attr( "userfile", userFile )
$('#theuploadform').attr( "MAX_FILE_SIZE", max )
$('#theuploadform').attr( "enctype", "multipart/form-data" )
$('#theuploadform').attr( "encoding", "multipart/form-data" )
$('#theuploadform').attr( "target", "postframe" )
$('#theuploadform').submit();
//need to get contents of the iframe
$("#postframe").load(
function(){
iframeContents = $("iframe")[0].contentDocument.body.innerHTML;
$("div#textarea").html(iframeContents);
}
);
return false;
});
});
</script>
```
I used a php app like this uploader.php to do something with the file:
```
<?php
$uploaddir = 'uploads/';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
$maxfilesize = $_POST[MAX_FILE_SIZE];
if ($maxfilesize > 5000000) {
//Halt!
echo "Upload error: File may be to large.<br/>";
exit();
}else{
// Let it go
}
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
print('File is valid, and was successfully uploaded. ');
} else {
echo "Upload error: File may be to large.<br/>";
}
chmod($uploadfile, 0744);
?>
```
There's more there than you need, but it illustrates the concept in jQuery. | I don't have the code handy but my team accomplished this purely in Javascript. As I recall it went something like this:
```
function postToPage() {
var iframe = document.getElementById('myIFrame');

] | [Google don't like copying or saving](https://developers.google.com/maps/terms) of their map/earth products. So I doubt it is possible within their API.
However it is possible to get a georeferenced gtiff of google maps imagery for a limited area through Qgis:
1. Use google street within the Openlayers plugin
2. Zoom to the area you want
3. Go to project -> Save as image and choose tif
4. Open the image, provide the correct projection info (EPSG: 3857)
5. Right click the image in the layers panel -> save as Gtiff
This is limited to the area within the map canvas, but if imagery for a larger area is needed, it can be repeated several times and the images tiled. But depending on your intended use this may be contravening the google terms of service. | [Downloading images from Google Maps is against the Terms of Service.](https://gis.stackexchange.com/questions/69962/download-google-map-tiles-images)
You can, however, embed maps using Google Maps APIs. See: [Google Static Maps Developer Guide](https://developers.google.com/maps/documentation/static-maps/intro) |

27,416,200 | I am posting because I have encountered a problem with one script that I am trying to develop .
What I am trying to create is a gallery that receives it's images from Instagram. In order to accomplish this two tasks I've found two plugins that fits my needs , but I am unable to fusion them both.
I'm relatively new to Jquery , and I do not understand why the script that I'm trying to run only affects one part of the code.
This example gallery has two fundamental parts :
1)Pre-loaded by the developer :
```
<div class="content-primary">
<ul class="iGallery" id="iGallery">
<li>
<a href="http://scontent-b.cdninstagram.com/hphotos-xfa1/t51.2885-15/10817900_1528499780732950_533530016_n.jpg">
<img src="http://scontent-b.cdninstagram.com/hphotos-xfa1/t51.2885-15/10817900_1528499780732950_533530016_s.jpg">
<li><a class="ui-link" href="http://scontent-b.cdninstagram.com/hphotos-xfa1/t51.2885-15/10831784_752863841449953_2058216615_n.jpg"><img src="http://scontent-b.cdninstagram.com/hphotos-xfa1/t51.2885-15/10831784_752863841449953_2058216615_s.jpg"></a></li></ul>
</a>
</li>
</ul>
```
And , the ones that are added dynamically thanks to the instagram api :
```
<script type="text/javascript">
(function() {
var s = document.createElement('script'), t = document.getElementsByTagName('script')[0];
s.type = 'text/javascript';
s.async = true;
s.src = 'http://api.flattr.com/js/0.6/load.js?mode=auto';
t.parentNode.insertBefore(s, t);
})();
/* ]]> */
function createPhotoElement(photo) {
var innerHtml;
innerHtml= $('<img>')
.attr('src', photo.images.thumbnail.url);
innerHtml = $('<a>')
.attr('href', photo.images.standard_resolution.url)
.append(innerHtml)
.append(innerHtml)
.addClass( "ui-link" );
return $('<li>')
.append(innerHtml);
}
function didLoadInstagram(event, response) {
var that = this;
$.each(response.data, function(i, photo) {
$(that).append(createPhotoElement(photo));
});
}
$(document).ready(function() {
var clientId = 'baee48560b984845974f6b85a07bf7d9';
$('.iGallery').on('didLoadInstagram', didLoadInstagram);
$('.iGallery').instagram({
hash: 'usa123',
count: 1,
clientId: clientId
});
});
</script>
```
Well , the main problem is that the part that handles the gallery seems to read only the part added manually , but not the ones that comes thanks to the instagram api .
I'm pretty sure that my problem is related to the time that the script is loaded , since the script changes some atributes of the images like `href to data-href` , but I've tried to pre-load that information , and I received the same results.
In order to give a visual idea of my problem , I have the script in codepen :
<http://codepen.io/anon/pen/XJdbZR>
And , this is the idea I have that tells me that only the per-loaded information is being modified by the script
I appreciate any kind of help or hint. Thanks | 2014/12/11 | [

] | There are many different [CoNLL](http://ifarm.nl/signll/conll/) formats since CoNLL is a different shared task each year. The format for CoNLL 2009 is described [here](http://ufal.mff.cuni.cz/conll2009-st/task-description.html). Each line represents a single word with a series of tab-separated fields. `_`s indicate empty values. [Mate-Parser's manual](https://mate-tools.googlecode.com/files/shortmanual.pdf) says that it uses the first 12 columns of CoNLL 2009:
```
ID FORM LEMMA PLEMMA POS PPOS FEAT PFEAT HEAD PHEAD DEPREL PDEPREL
```
The definition of some of these columns come from earlier shared tasks (the [CoNLL-X format](https://web.archive.org/web/20160814191537/http://ilk.uvt.nl/conll/#dataformat) used in 2006 and 2007):
* `ID` (index in sentence, starting at 1)
* `FORM` (word form itself)
* `LEMMA` (word's lemma or stem)
* `POS` (part of speech)
* `FEAT` (list of morphological features separated by |)
* `HEAD` (index of syntactic parent, 0 for `ROOT`)
* `DEPREL` (syntactic relationship between `HEAD` and this word)
There are variants of those columns (e.g., `PPOS` but not `POS`) that start with `P` indicate that the value was automatically predicted rather a gold standard value.
**Update:** There is now a [CoNLL-U](http://universaldependencies.github.io/docs/format.html) data format as well which extends the CoNLL-X format. | As update to @dmcc's answer:
* CoNLL is the conventional name for TSV formats in NLP (TSV - tab-separated values, i.e., CSV with `<TAB>` as separator)
* It originates from a series of shared tasks organized at the Conferences of Natural Language Learning (hence the name)
* Not all of these tasks use "CoNLL" formats, some tasks had JSON or XML formats
* There are "CoNLL" formats that developed independently from CoNLL, most notably CoNLL-U
* CoNLL formats differ in the choice and order of columns
In CoNLL formats,
* every word (token) is represented in one line.
* every sentence is separated from the next by an empty line
* every column represents one annotation
* every word in a sentence has the same number of columns (in some formats: every word in the corpus has the same number of columns)
* an annotation is a string value about a particular word
* annotations that span over multiple words sometimes use special notations, e.g., round brackets (indicating begin and end of a phrase) or the IOBES-annotation (e.g., B-NP: begin of NP, I-NP: in the middle of NP, E-NP: end of NP, S-NP: NP begins and ends at the current word, O: no NP annotation)
* some CoNLL formats have one or multiple columns of numerical identifiers as the first column, the next column after these (or the first if there are no IDs) usually contains the WORD
* the ID of the first word in the sentence is 1. If no ID column is provided, the ID is the number of preceding words within the sentence plus 1.
* in dependency syntax, grammatical relations hold between words, the dependent is marked for the HEAD (= ID of the parent word) and the EDGE/DEP[endency] (= grammatical relation), both in separate columns
* if a word in dependency syntax does not have a parent (i.e., it is the syntactic root), set its HEAD to 0
Be careful when working with tools or libraries that claim to support (some) "CoNLL format". Different CoNLL formats have different order of columns and the developer might not be aware of that. So, it is likely that they don't work as expected if they get data from another (or unspecified) CoNLL format.
For converting between different CoNLL formats, you can consider using CoNLL-RDF (<https://github.com/acoli-repo/conll-rdf>), resp., CoNLL-Transform (<https://github.com/acoli-repo/conll-transform>) (Disclaimer: Developed by my lab.) |
1,294,568 | I have a data set that looks like the table shown on the left. The data has 3 columns, ranked by values in column 3; column 1 is the index of the row in the ranking; column 2 is the 'category' assigned to that row.

] | You *could* edit and change the marker style for just those two points. But that causes some difficulties with the labels in the legend.
A better solution is to arrange your data table as shown below. That causes Excel to plot the data as two separate series, and then you can format the two series separately as you wish.

=IF([some condition],[some value],NA())
This puts #N/A into the cell, and the chart ignores the point. See my recent tutorial [Plot Blank Cells and #N/A in Excel Charts](https://peltiertech.com/plot-blank-cells-na-in-excel-charts/) for more details. | I was able to do this as a single series scatter plot, 1st column vs. 3rd column, where I set the markers of the series to 'None'.
To get the correct markers I used data labels where the label contained the value from the second column. I placed the labels on the 'Center' position. For the second column I replaced the A and B by appropriate shapes from the Wingdings font.
Note: also in the graph then you need to set the font of the labels to Wingdings.
Note 2: If you want to keep the A's and B's also, you could make a 4th column where you create the label based on the A/B column with a simple IF statement (=IF(B1="A","l","n") -- "l" and "n" in wingdings font are circles and squares)
A two-series will also work without the trick with the labels but then you need to rearrange your data such that you have uninterrupted sections of A's and B's. |

You shouldn't assume you received a notification just because a thread exited from a call to Object#wait, for multiple reasons:
* When calling the version of wait that takes a timeout value there's no way to know whether wait ended due to receiving a notification or due to timing out.
* You have to allow for the possibility that a Thread can wake up from waiting without having received a notification (the "spurious wakeup").
* The waiting thread that receives a notification still has to reacquire the lock it gave up when it started waiting, there is no atomic linking of these two events; in the interval between being notified and reacquiring the lock another thread can act and possibly change the state of the system so that the notification is now invalid.
* You can have a case where the notifying thread acts before any thread is waiting so that the notification has no effect. Assuming one thread will enter a wait before the other thread will notify is dangerous, if you're wrong the waiting thread will hang indefinitely.
So a notification by itself is not good enough, you end up guessing about whether a notification happened when the wait/notify API doesn't give you enough information to know what's going on.

Even if other work the notifying thread is doing doesn't require synchronization, updating the condition variable does; there should at least be an update of the shared condition variable in the synchronized block. | The Java API documentation for [Object.notify()](http://download.oracle.com/javase/6/docs/api/java/lang/Object.html#notify%28%29) states that the method "should only be called by a thread that is the owner of this object's monitor". So the use could be legitimate depending upon the surrounding context. |

40,995,032 | I have an idea for a code style for writing specific kinds of numerical algorithms where you write your algorithm purely in data-layout agnostic fashion.
i.e. All of your functions take (one or more) scalar arguments, and return (through a pointer) one or more scalar return values. So, for example, if you have a function that takes a 3d float vector, instead of taking a struct with three members, or float[3] xyz, you take float x, float y, float z.
The idea is that you can change the layout of your input and output data, i.e. you can play with struct of array vs. array of struct data layout, tiled layouts for cache efficiency, SIMD vs. multicore granularity, etc... WITHOUT having to rewrite all of your code for all combinations of data layouts.
The strategy has some obvious downsides:
* You can't use for loops inside your functions to make your code more compact
* Your functions need more parameters in their signatures
...but those are palatable if your arrays are short and it saves you having to rewrite your code a bunch of times to make it fast.
But in particular, I am worried that compilers might not be able to take stuff like x+=a; y+=b; z+=c; w+=d and autovectorize it into a single SIMD vector add, in the case where you want to do SIMD at the bottom of your call stack, as opposed to doing SIMD at the top of a stack of inlined functions.
Are clang and/or gcc able to "re-roll" manually unrolled loops in C and/or C++ code (probably after functions are inlined) and generate vectorized machine code? | 2016/12/06 | [

float out[4])
{
// This is a stand-in for the main function below, but since the arrays are aguments,
// they can't be optimized out of the non-inlined version of this function.
// THIS version DOES compile into (I think) a bunch of non-aligned moves,

&out[0],&out[1],&out[2],&out[3]
);
}
int main(int argc, char **argv)
{
}
```
Consider the generated assembly for add4\_then\_sub4\_arrays:
```
0000000000400600 <add4_then_sub4_arrays>:
400600: 0f 57 c0 xorps %xmm0,%xmm0
400603: 0f 57 c9 xorps %xmm1,%xmm1
400606: 0f 12 06 movlps (%rsi),%xmm0
400609: 0f 12 0f movlps (%rdi),%xmm1
40060c: 0f 16 46 08 movhps 0x8(%rsi),%xmm0

40062b: c3 retq
40062c: 0f 1f 40 00 nopl 0x0(%rax)
```
The arrays aren't aligned, so there are a lot more move ops than ideal, and I'm not sure what that xor is doing in there, but there is indeed one 4-way add and one 4-way subtract as desired.
So the answer is that gcc has at least ~some ability to pack scalar floating point operations back into SIMD operations.

``` | Your concern is correct. No compiler is going to autovectorize those 4 adds. It's simply not worth it, considering the inputs aren't contiguous and aligned. The cost of gathering arguments into a SIMD register are much higher than the saving of a vector addition.
Of course, the reason the compiler can't use an aligned streaming load is because you passed the arguments as scalars. |

Check out
```
RectF r = new RectF(/*your bitmap's corners*/);

Yes. You can filter out resources by project/folder path. Refer this answer <https://stackoverflow.com/a/39568618/1391924> | Open Resource and Open Type both let You use *Working Sets*.

Do not fix this problem by change server's SQL Mode. Fix it by altering the queries which uses partial `GROUP BY` expressions.

Do note that this is not a bug, this is the way it is supposed to work. By disabling this check you risk getting indeterministic answers from your queries. A small example:
```
create table t (x int not null, y int not null, z int not null);
insert into t (x,y,z) values (1,1,2),(1,2,3);
```
What would be the result of:
```
select x,y,max(z) from t group by x
```
? MAX(z) in the group x is 3. What value should y have, 1 or 2? This would be logically valid if y were functionally dependent on x, but in this case, there is neither a constraint that guarantees it nor data that conforms to it. |

Getting the values from the UI makes sense, but then you loop over `bin_add`, which obviously doesn't actually add anything, or you wouldn't need to loop or have a class variable. All of this logic should happen inside of `bin_add`.
`bin_add` should take in two strings, handle all of the logic, and return a single string representing the output. While I'm at it, methods should have PascalCased verb-noun names. This method should be called `AddBinary` and I will refer to it as such for the rest of the review.
As I said earlier, I wouldn't expect a Function that adds binary numbers to take in Boolean values. I would rather it actually take in a byte and overload the method to handle string representation, but I'm lazy and you don't seem to need all that.
Putting it all together, the signature line

function redirectToURL() {

] | First, you are violating the [DRY principle](https://en.wikipedia.org/wiki/Don%27t_repeat_yourself). Instead of having separate variables for each set of products, store each of them in a sort of dictionary structure such as an object.
This would be my **first revision**.
```
var dict = {
a: ["V1-1: 1/4-4 900-4500#", "V1-1 Light-Weight Compact Solution", "V1-2: 1/2-36 150-600#","V1-3: 1/2-2, 150-600#","V1-4: 4-36 900-4500#"],

$(function() {
// attach an 'change' event handler
// THEN trigger the event handler to call the function from the start
$('#cat').change(populateSelect).trigger('change');
});
function populateSelect() {
// this refers to the current element
// get the selected value
var cat = this.value;
// always a good idea to cache your element that you will be re-using (maybe move it outside the function too)
var items = $('#item');
items.html('');
// check if there are products associated with the selected value
if (dict.hasOwnProperty(cat)) {
// show products
dict[cat].forEach(function(product) {
items.append('<option>' + product + '</option>');
});
}
}
```
Now, in terms of your actual problem. We can modify the arrays, so that it also includes a url. You could have arrays of arrays for simplicity e.g.
>
> a: [["V1-1: 1/4-4 900-4500#", "url"], ["V1-1 Light-Weight Compact
> Solution", "url"], ...]
>
>

or arrays of objects for readability e.g.

> Light-Weight Compact Solution", url: "url"}, ...]

So here's my **second revision** using arrays of objects. (I shorten the dictionary just to show illustration).

}
],
c: [{

};
$(function() {
// cache element so that you don't re-search the DOM multiple times
var $items = $('#item');
$('#cat').change(populateSelect).trigger('change');
$('#goto').click(redirectToURL);
// place the functions within the document.ready so that they have access to the cached elements
function populateSelect() {
$items.html('');
if (dict.hasOwnProperty(this.value)) {
dict[this.value].forEach(function(product) {
// you can store the URL in HTML5-data attribute to use it later
$items.append('<option data-url="' + product.url + '">' + product.name +'</option>');
});
}
}
function redirectToURL() {
// get the URL from the selected option's data-url and redirect to it
window.location.href = $items.find(':selected').data('url');
}
});
```
Technically, you are not "submitting" a form but just "redirecting" -- so I would not use a submit button but just an ordinary button.
```
<input type="button" id="goto" value="submit">
```
Below is a [demo](http://codepen.io/anon/pen/KNMWBa) of the final revision. You'll have to fix the dictionary. | I think that I would take this approach. Store an array of objects, each of which contain the product name and the appropriate url for that product. Then (assuming you are using a form) you can change the action of form to the value of the selected option.
Side notes: It's recommended to use the bracket notation (`[]`) instead of `new Array()`. You can read more about this [here](https://stackoverflow.com/a/1800603/6069012) and at other sources. Also, since your `cat` will only ever be one value when you're in the `populatSelect` function, you should use the `if..else if..else if..` structure. In the case of a match, you will leave the `if..else if` expression completely, saving time. Whereas if you kept `if..if..if..`, you would have to evaluate all of them even if you found a match right away.
**EDIT**: You should definitely follow the concepts that some of the other answers are using (namely using a dictionary, which will allow you to retrieve the correct category without all the `if` checks).
```
var cats = {
a: [
{ product: 'V1-1: 1/4-4 900-4500#', url: '<product url>' },
{ product: 'V1-1 Light-Weight Compact Solution', url: '<product url>' },

{ product: 'V1-4: 4-36 900-4500#', url: '<product url>' }
],
b: [

{ product: 'NexTech® E Series Valves', url: '<product url>' },
{ product: 'TrunTech® Valves', url: '<product url>' },
{ product: 'PulseJet Valves', url: '<product url>' }

// same for the rest of your categories
};
populateSelect();
$(function() {
$('#cat').change(function(){
populateSelect();
});
});
function populateSelect(){
var cat = $('#cat').val();
$('#item').html('');
appendProducts(cats[cat]);
}
function appendProducts(arr) {
arr.forEach(function(t) {
$('#item').append('<option value="' + t.url + '">'+ t.product +'</option>');
});
}

Literally, you can think about it as 'one part of seven'. It is not a ratio, i.e. 'one part to seven parts', as that equates to 1/8. | Yes, 「７分の１」 means same as 1:7 mathematically.
1:7 = (1/8):(7/8) = (1/8)/(7/8) = (1/8)x(8/7) = 8/56 = 1/7
However, in Japan, kids are taught that 1:7 is 「[比]{ひ}」 and 1/7 is 「[分数]{ぶんすう}」. I guess that 「比」 is translated as "ratios", and 「分数」 is translated as "fractions" generally. So, Japanese people tend to think that 1/7 is not a ratio, maybe.
In English, both 1:7 and 1/7 can be read "one to seven", right? And both 1:7 and 1/7 are called "ratio" in some cases, maybe? (Sorry, if my knowledge about English is wrong.) But in Japanese, each of them has its own way to be read.

Which word should be used is up to the situation and context.
If your "ratio" means both 1:7 and 1/7, I would answer that there are several ways to write ratio in Japanese, and 「７分の１」 is one of them. So, yes. |
62,216,682 | Suppose we have the following class:
```py
from __future__ import annotations
class BaseSwallow:
# Can't get the ref to `BaseSwallow` at runtime
DerivedSwallow = NewType('DerivedSwallow', BaseSwallow)
def carry_with(self, swallow: DerivedSwallow):
self.carry()
swallow.carry()
def carry(self):
pass
class AfricanSwallow(BaseSwallow): pass
godOfSwallows = BaseSwallow()
africanSwallow = AfricanSwallow()
africanSwallow.carry_with(godOfSwallows) # Should fail at static typing
```
I want to enforce that `carry_with` should only be called with instances of classes **derived from** `BaseSwallow`, so I use `NewType` to do that [like the doc says](https://docs.python.org/3/library/typing.html#distinct).
However, `NewType` needs a reference to the base class object to work, and I don't have access to that at runtime. Before runtime, I have "access" to `BaseSwallow` thanks to the `annotations` module but it will still fail when running.
I'm aware that using an Abstract Base Class for `BaseSwallow` is the best thing to do here in most cases, but I can't do that [for various reasons](https://stackoverflow.com/q/59638421/5989906).
Any idea ? | 2020/06/05 | [

] | I don't think there's a way to express "all subclasses of `T` excluding `T`" using type annotations. If you have a fixed set of subclasses you could use a `Union` type to capture them all, but that's probably not what you want. I think [Sam's answer](https://stackoverflow.com/a/62220325/4909228) is your best bet: just use the `BaseSwallow` base class instead of crafting a complicated type to rule out the base class itself.
Also, I think you misunderstood the usage for `NewType`. `NewType` is used to create an alias of a type that requires explicit conversion. For example:
```py
URL = NewType('URL', str)
def download(url: URL): ...
link_str = "https://..." # inferred type is `str`
link_url = URL(link_str) # inferred type is `URL`
download(link_str) # type error
download(link_url) # correct
```
---
**Edit:** If you don't mind a little bit of overhead, you can achieve this with an additional level of inheritance. Create a subtype of `BaseSwallow` (named `Swallow` for convenience), and have all the derived classes inherit `Swallow` instead of `BaseSwallow`. This way, you can annotate the `carry_with` method using the `Swallow` type:
```py
class BaseSwallow:
def carry_with(self, swallow: 'Swallow'): # string as forward reference
self.carry()
swallow.carry()
def carry(self):
pass
class Swallow(BaseSwallow): pass # dummy class to serve as base
class AfricanSwallow(Swallow): pass
godOfSwallows = BaseSwallow()
africanSwallow = AfricanSwallow()
africanSwallow.carry_with(godOfSwallows) # mypy warns about incompatible types
``` | can you just mark `carry` as an [`abstractmethod`](https://docs.python.org/3/library/abc.html#abc.abstractmethod)? for example, something like:
```
import abc
class BaseSwallow:
def carry_with(self, swallow: BaseSwallow) -> None:
self.carry()
swallow.carry()
@abc.abstractmethod
def carry(self) -> None:
raise NotImplementedError('implementation of carry needed')
```
derived classes could then implement the method, but because the base class didn't attempts to instantiate it would cause type checking to fail saying that `BaseSwallow` is an abstract class due to missing attribute `carry` |

71,500 | The majority of primates have really thick nails, though not as broad or flat as humans'. However, marmosets have 18 claws, and only their big toes have nails. What differences in evolutionary pressures caused this? And how does the structural relationship between marmosets' germinal matrices and their distal phalanxes differ from other primates, so they can grow claws? | 2018/03/18 | [
"https://biology.stackexchange.com/questions/71500",
"https://biology.stackexchange.com",

] | Since marmosets and tamarins are considered the most primitive primates, we can't assume that evolutionary pressure led to the development of claws. Rather, it's accepted that claws disappeared as primates adapted to an arboreal lifestyle. So the question is really "Why did marmosets not completely lose their claws?"
The clues to the answer lie in their unusually large incisors and disgestive system. The marmoset occupies an evolutionary niche where they rely heavily (20-70% of total diet) on exudates (sap, resin, etc.) from trees. Their claws, and incisors allow them to claw/chew holes in the bark to get at the exudates, while a specially adapted large intestine allows them to digest this food. The advantage of exudates is they are not seasonal, offering the marmoset a relatively stable year-round food supply.
Other primates enjoyed the evolutionary benefits of tool use by losing their claws and gaining opposable thumbs (which marmosets don't have). I've come across no papers that describe a different phlange structure for marmosets and other primates, and there doesn't necessarily need to be one.
Most of this information came from the University of Wisconsin's Primate Research Center:
<http://pin.primate.wisc.edu/factsheets/entry/common_marmoset>
Edited to add (since I can't comment): One way to deduce how different features evolved is to look at phylogenetic trees. There are many out there, but I pulled this one from J.R. Roede et al. *Redox Biology* 1 (2013) 387-393.
[](https://i.stack.imgur.com/vEv4A.png)
If you look at this simple tree, you'll see that marmosets diverged from humans on a time frame where it's possible they kept their claws instead of reacquiring this trait (it would be unusual, but not impossible, for this to happen). One thing you can do is dive deeper into the phylogeny, square this up with how primate hands evolved, and see if the split of marmosets from the rest of the primates happened when nails began to evolve. | Ill try and research this later and add references, it's a bit of a draft version while im on laptop in the car, A good place to think but not to write and surf from!
It's probably best viewed as a vestigial trait, made redundant by monkey's prehensile grasp, and related to their strong social and hierarchical behaviour. Indeed the flat nails seem to be a progressive arrival transitioning from lemures/aye-ayes to larger prehensile primates.
Humans have the most vestigial nails, to protect the fingers and for fine fingertip manipulation, and earlier mammals and non-prehensile herbivores find advantage of pointy nails for grasping bark and defense, to decorticate husks rinds, to dig, and other tasks.
We can imagine if nails had become reduced vestigial tools in a different way to what they did, imagine that they had tapered into bulbous tips
We can consider other alternatives that could have evolved, but the flat shape seems most fitting for a finger protection and versatility.
Also consider that large monkeys are belligerent, for example baboons which are very fierce, and monkeys that have sharp teeth which they can use in combat. If they had claws to do demonstrative fighting, it may be less beneficial for the group, and nails would generally discourage the mostly demonstrative social competition which is found in most social and rutting creatures. It demonstrates the contrast of vestigial carnivorous traits of some primates compared to the herbivorous organs of the largest ones.
With regards to the structure, perhaps it's best to check other mammals fingernails to see that it's only a small proportional and dimensional change.
Conical nails require a different shaped matrix which doesn't fit on top of fingertips for grooming and find dexterity, to alight with the bone, the nail matrix surrounds the top of the finger bone, so it's easy to broaden and thin out.
It's matrix cells that generate keratin which is not structurally affixed to the bone, which means it can regenerate efficiently, while it has structural weakness for lifting bodyweight. For carnivores, the stress on the nail is reduced by the cutting edge. The structural difference is not very pronounced. web resources for primate nail anatomy aren't abundant but you can find trees of primate hand anatomy. |

] | 'Distributed Transaction Coordinator' service was not running, So started service and changed service type to automatic too. | Recently this appeared as an issue on my work machine (Win 10, MSSQL 2016 SP2 Express). I do not have linked servers. This appeared from nothing. The MSDTC service is running, MSSQL works fine using the Mgmt Studio. However my .NET 4.7.1 Unit test app refuse to connect with the database with that "MSDTC on server '...' is unavailable" error.
The temporal workaround I found is to add "Enlist=False;" at the end of the connection string to avoid using MSDTC at all for the connection.

I do not have linked servers. This appeared from nothing. The MSDTC service is running, MSSQL works fine using the Mgmt Studio. However my .NET 4.7.1 Unit test app refuse to connect with the database with that "MSDTC on server '...' is unavailable" error.
The temporal workaround I found is to add "Enlist=False;" at the end of the connection string to avoid using MSDTC at all for the connection.

```
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
Log.i(WIDGETTAG, "onUpdate");
final int N = appWidgetIds.length;
// Perform this loop procedure for each App Widget that belongs to this provider
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];
Log.i(WIDGETTAG, "updating widget[id] " + appWidgetId);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
/* View setup */
views.setInt(R.id.widgetTitle, "setBackgroundColor", Color.argb(150, 0, 0, 0));
Intent intent = new Intent(context, ChopInkService.class);
intent.setAction(ChopInkService.UPDATE_IMAGE);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
PendingIntent pendingIntent = PendingIntent.getService(context, 0, intent, 0);
views.setOnClickPendingIntent(R.id.widgetBackground, pendingIntent);
Log.i(WIDGETTAG, "pending intent set");
// Tell the AppWidgetManager to perform an update on the current App Widget
appWidgetManager.updateAppWidget(appWidgetId, views);
}
```
3. What is the job for **Service** and **AppWidgetProvider**?
* Load image from url is the job of **service** or **AppWidgetProvider**?
* View setup should put in **service** or **AppWidgetProvider**?
4. How can I redirect user to play store when user tapped on the widget?

] | **Available Widget views & Layout**
A **widget** is restricted in the View classes it can use. As layouts you can use the **FrameLayout, LinearLayout** and **RelativeLayout** classes. As views you can use AnalogClock, Button, Chromometer, ImageButton, ImageView, ProgressBar and TextView.
As of Android 3.0 more views are available: **GridView, ListView, StackView, ViewFlipper and AdapterViewFlipper.** This adapter Views require that you define a collection view widget which is described later in this tutorial.
The only interaction that is possible on the Views of a Widget is via on OnClickListener. This OnClickListener can be registered on a widget and is triggered by the user.
**AppWidgetProvider**
Your **BroadcastReceiver** typically extends the **AppWidgetProvider** class.
The AppWidgetProvider class implements the **onReceive()** method, extracts the required information and calls the following widget lifecycle methods.
As you can add several instances of a widget to the homescreen you have lifecycle methods which are called only for the first instance added / removed to the homescreen and others which are called for every instance of your widget.
**Lifecycle of Widget**
**onEnabled()** -Called the first time an instance of your widget is added to the homescreen
**onDisabled()** -Called once the last instance of your widget is removed from the homescreen.
**onUpdate()** -Called for every update of the widget. Contains the ids of appWidgetIds for which an update is needed. Note that this may be all of the AppWidget instances for this provider, or just a subset of them, as stated in the methods JavaDoc. For example if more than one widget is added to the homescreen, only the last one changes (until reinstall).
**onDeleted()** -Widget instance is removed from the homescreen
All long running operations in these methods should be performed in a service, as the execution time for a broadcast receiver is limited. Using asynchronous processing in the onReceive() method does not help as the system can kill the broadcast process after his onReceive() method.

2. How to load the image from web and display on the layout in java code? Below is my widget provider code:
```
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
Log.i(WIDGETTAG, "onUpdate");
final int N = appWidgetIds.length;
// Perform this loop procedure for each App Widget that belongs to this provider
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];
Log.i(WIDGETTAG, "updating widget[id] " + appWidgetId);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
/* View setup */
views.setInt(R.id.widgetTitle, "setBackgroundColor", Color.argb(150, 0, 0, 0));
Intent intent = new Intent(context, ChopInkService.class);
intent.setAction(ChopInkService.UPDATE_IMAGE);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
PendingIntent pendingIntent = PendingIntent.getService(context, 0, intent, 0);
views.setOnClickPendingIntent(R.id.widgetBackground, pendingIntent);
Log.i(WIDGETTAG, "pending intent set");
// Tell the AppWidgetManager to perform an update on the current App Widget
appWidgetManager.updateAppWidget(appWidgetId, views);
}
```
3. What is the job for **Service** and **AppWidgetProvider**?
* Load image from url is the job of **service** or **AppWidgetProvider**?
* View setup should put in **service** or **AppWidgetProvider**?
4. How can I redirect user to play store when user tapped on the widget?

] | **Available Widget views & Layout**
A **widget** is restricted in the View classes it can use. As layouts you can use the **FrameLayout, LinearLayout** and **RelativeLayout** classes. As views you can use AnalogClock, Button, Chromometer, ImageButton, ImageView, ProgressBar and TextView.
As of Android 3.0 more views are available: **GridView, ListView, StackView, ViewFlipper and AdapterViewFlipper.** This adapter Views require that you define a collection view widget which is described later in this tutorial.
The only interaction that is possible on the Views of a Widget is via on OnClickListener. This OnClickListener can be registered on a widget and is triggered by the user.
**AppWidgetProvider**
Your **BroadcastReceiver** typically extends the **AppWidgetProvider** class.
The AppWidgetProvider class implements the **onReceive()** method, extracts the required information and calls the following widget lifecycle methods.
As you can add several instances of a widget to the homescreen you have lifecycle methods which are called only for the first instance added / removed to the homescreen and others which are called for every instance of your widget.
**Lifecycle of Widget**
**onEnabled()** -Called the first time an instance of your widget is added to the homescreen
**onDisabled()** -Called once the last instance of your widget is removed from the homescreen.
**onUpdate()** -Called for every update of the widget. Contains the ids of appWidgetIds for which an update is needed. Note that this may be all of the AppWidget instances for this provider, or just a subset of them, as stated in the methods JavaDoc. For example if more than one widget is added to the homescreen, only the last one changes (until reinstall).
**onDeleted()** -Widget instance is removed from the homescreen
All long running operations in these methods should be performed in a service, as the execution time for a broadcast receiver is limited. Using asynchronous processing in the onReceive() method does not help as the system can kill the broadcast process after his onReceive() method.

] | Another way is to use:
```
includeScript("mapManipulator.js"),
``` | Another option not discussed yet is that you just delete the ui.R file entirely, and then code the entire thing as a custom HTML file. Details here <https://shiny.rstudio.com/articles/html-ui.html>
In this article, the default HTML form elements are automatically used as inputs in server.R, but you can also build custom input (or output) elements for shiny with this guide <https://shiny.rstudio.com/articles/building-inputs.html> |
23,599,278 | How can I go out of the currect directory and access the test.php file?
I have tried the following:
```
realpath(__dir__.'../test.php');
realpath(__dir__.'./test.php');
```
But it does not work!
Also could you please let me know what is the difference between ./ and ../ ?
UPDATED:
The following lines give the following results:
```
echo(__dir__.'\tests.php');
echo "<br/>";
echo(__dir__.'..\tests.php');
echo "<br/>";
echo(realpath(__dir__.'..\tests.php'));
echo "<br/>";
echo "hi";
die();
Result:
C:\xampp\htdocs\proj1\includes\tests.php
C:\xampp\htdocs\proj1\includes..\tests.php
hi

] | Another way is to use:
```
includeScript("mapManipulator.js"),
``` | My preferred way is like this:
ui.R:
```
extendShinyjs(script = "app.js", functions = c("alerta")),
```
app.js:
```
shinyjs.alerta = function(text){
alert(text);
}
```
server.R
```
js$alerta("alerta alerta antifascista")
```
You can also include code like this:
ui.R after library imports:
```
jsCode <- "shinyjs.alerta = function(text){alert(text);}"
```
ui.R inside fluidPage:
```
extendShinyjs(text = jsCode, functions = c("alerta")),
```
the call from server.R would be the same |
22,966,279 | Is there a possibility where I can make a button on which when I click, the contents directly get shared on facebook without showing our user the share prompt dialog box?
I referred it online and found that its possible through mobile devices:
<http://www.mindfiresolutions.com/How-to-post-message-on-your-facebook-wall-without-using-Facebook-dialog-Box-1419.php>
The question is can we make some sort of ajax call and get this done on web apps.
We used Following code
```
<?php
require_once('php-sdk/facebook.php');
$config = array(
'appId' => 'My app ID', /*Your APP ID*/
'secret' => 'My Secret ID', /*Your APP Secret Key*/
'allowSignedRequest' => false
);
$facebook = new Facebook($config);
$user_id = $facebook->getUser();
if($user_id) {
try {
$user_profile = $facebook->api('/me','GET');
} catch(FacebookApiException $e) {
$login_url = $facebook->getLoginUrl();
echo 'Please <a href="' . $login_url . '">login.</a>';
error_log($e->getType());
error_log($e->getMessage());
}
} else {
// No user, print a link for the user to login
$login_url = $facebook->getLoginUrl();
echo 'Please <a href="' . $login_url . '">login.</a>';
}
$response = $facebook->api(
"/me/feed",
"POST",
array (
'message' => 'This is a test message',
'link' => 'www.google.com'
/* 'picture' => '{picture}',
'caption' => '{caption}',
'description' => '{description}'*/
)
);
?>
```
But its returns : " Fatal error: Uncaught OAuthException: (#200) The user hasn't authorized the application to perform this action throw in file"
Any help would be highly appreciated.

**Edit:**
To ask for the required permissions:
```

$login_url = $facebook->getLoginUrl($params);
```
You can read more about permissions [here](https://developers.facebook.com/docs/facebook-login/permissions/). | Try this way: <https://developers.facebook.com/docs/reference/php/>
When coding the wep app, you only have to provide the App Id and the App Secret, then you should have to specify the content to be posted.
You should try also the Javascript Facebook SDK, you'll find it here: <https://developers.facebook.com/docs/javascript> or you could go further and try the C# SDK, this one is a little bit more complex, but you will be able to do so much more.
Have fun coding!!! |

```
var myThings = {
thing1: [

['25-04-12', '30'],
['26-04-12', '210']

```
Now since `thing1` and `thing2` are `Arrays` you can just use `Array.prototype.push` to push new `Arrays` into that `Array`.
```
Object.keys( myThings ).forEach(function( thing ) {
myThings[ thing ].push( ['01-01-12', '42'] );
});
```
That code would add `['01-01-12', '42']` to all current `things` in that object.
Disclaimer: The above code contains ES5. You need a browser which supports that or a Shim to emulate | I'd do:
```
//create your array dynamically
var array1 = [['24-04-12', '90'],
['25-04-12', '90'],
['26-04-12', '90'] ];
var myThings = {
thing1: array1
,
thing2: array1
}
```
