## sharepoint online – Javascript REST results processing

I’m using JavaScript to pull data from a SharePoint 2013 list. The REST request works fine and I can see the data in the debug windows of Chrome. I am struggling to determine how to access specific pieces of the data.

When I open the Chrome tools I can see the object and it looks like this {d:{…}}. I can expand it and look at the data.

What I have not been able to do is access specific elements say for example the Title column information for element 0. I’ve tried data.results(0).Title and other ways but nothing.

I can write the code to grab what I need just need to understand how to access the data in the code first.

Thanks for the help.

The REST call I’m using is as follows:

``````    var srcListName="MyList";
var oDataUrl="https://somesharepoint.com/_api/web/lista/getbytitle('"+srcListName+"')/items?\$;
\$.ajax({
url:oDataUrl,
type:"GET",
dataType: "json",
success:mySuccHandler,
error: myErrHandleer});

function mySuccHandler(data){
console.log(data);
}
function myErrorHandler(data,errMessage){

}

## 7 – Remove duplicated results – Apache Solr

English is not my native language so please be patient.

Good afternoon, my Drupal 7 site is currently holding several articles, help topics, and document guides that are versioned, i.e search the “chocolate” word :

Product Cake:

• title: Old aunt’s Chocolate Cake. Version: 1.0
• title: Old aunt’s Chocolate Cake. Version: 1.2
• title: Colombian Cake, Coffee, and Chocolate. Version: 1.0

Product Candy:

• title: Chocolate candy for fitness. version: 1.0
• title: Gretel’s Chocolate recipe. version: 2.2
• title: Gretel’s Chocolate recipe. version: 3.0
• title: Gretel’s Chocolate recipe. version: 1.0

Product Beverage:

• title: Milk & Chocolate. version: 1.0
• title: Milkshake for the boys in the yard: Vanilla, Chocolate, and More. version: 1.0
• title: Milkshake for the boys in the yard: Vanilla, Chocolate, and More. version: 2.1
• title: Hot Chocolate for Cold Winters. version: 1.0

Currently, the site is using Apache Solr Search and related modules. I haven’t been able to set a hook that would allow removing the duplicate results for versions with the same title but different versions, ideally I would like to have results for the latest version only.

The Apache Solr Sort module supposedly would do the trick, sadly I’m still getting the same results sorted by most recent creation, but due to those articles having (almost) the same score none of the duplicated versions are removed.

To handle the sort by most recent creation date I have modified the score using the creation date.

Also, is possible to achieve the sort using the Apache Solr search module.

But to remove duplicate results, still haven’t found a solution. The documentation says that my necessity would be solved implementing Grouping, but no result comes from Apache Solr using the following hook_apachesolr_query_prepare which is based in the Sort module, Is this the correct way to implement Grouping? Is there another option to remove the duplicate versions?

``````/**
* Implements hook_apachesolr_query_prepare().
*/
function custom_search_apachesolr_query_prepare(\$query) {

\$env_id = \$query->solr('getId');
\$process_callback = apachesolr_environment_variable_get(\$env_id, 'process_response_callback', 'apachesolr_search_process_response');
\$group_field = apachesolr_environment_variable_get(\$env_id, 'group_field', 'title');
\$group_limit = apachesolr_environment_variable_get(\$env_id, 'group_limit', '10');

if (\$process_callback == "apachesolr_sort_process_response") {
array(
'group' => 'true',
'group.field' => \$group_field,
'group.limit' => \$group_limit,
'group.ngroups' => 'true',
'group.sort' => 'ds_created desc',
'group.facet' => 'true',
)
);
// start params are different. You should move similar to the group.limit amount
if (isset(\$query->page)) {
\$query->removeParam('start');
}
if (isset(\$query->page)) {
}
}
}

## SharePoint search API not bringing results from Subsites

I am trying to use Search Api in SharePoint online to search against a RefinableString that is mapped to to a column

``````https://tenant.sharepoint.com/sites/SiteName/_api/search/query?querytext='RefinableString00:SomeQueryText'&rowlimit=500&selectproperties='Title,RefinableString00'
``````

When I query this, it brings the documents from the root site collection only. When I include the `path:"http://pathToSubsite"` in querytext, it brings the document from that subsite only. So if want to bring results from all the subsites, do I need to include all of them in the path?

Not sure what I am missing in the query. Also I noticed that it the result is containing only one result even when we have more than 1 matching results in the site.

## DOCKER: every command results in a fatal error: runtime: out of memory

To add context, I have a small server with 1GB memory on which I am trying to deploy a lot of shiny apps by dockerizing ShinyProxy using docker-compose.

I am adding app after app on ShinyProxy and testing it step by step. It used to work for the 4-5 first apps but now when I build my container using docker-compose up –build -d, I ended up with the following error from which I cannot get out…

The problem is that every time I connect through ssh to my server, every docker command results in this error. I am literally stuck with it and don’t know how to get out.

I hope some docker pros can help me with this issue.

Thanks & Regards,

## equation solving – LinearSolve and LeastSquares giving different results on system with a solution

So I’m working on a program for my PhD which is supposed to do the following: Take a function f, build a matrix A with `Table(Coefficient(f(n*x + k + i - 1), x^j), {i, n}, {j, Deg})` (Deg is the degree of f, n is arbitrary positive integer), then take a function g of the same degree as f and construct a vector B with `Table(Coefficient(g(x + m), x^j), {j, Deg})`, then solve A.x = B for x in terms of k,m and then find at least one integer value of k,m so that each entry of x is nonnegative. If n = Deg then it’s a square matrix and it’s possible to show that A will always be invertible, and max rank if it’s nonsquare.

But for some reason (for a specific case of f = x^3, g = (2x+1)^3) when A is 3×2, using `LeastSquares(Transpose(A),B)` gives me the correct solution whereas `LinearSolve(Transpose(A),B)` tells me there is no solution, and when A is 3×4 (now for the case f = x^3, g = (4x+1)^3), the exact opposite happens. (Due to the nature of the problem, given any n I can choose f,g so that I know there is a solution for that n, and I know what one of the solutions is.) I’m really confused because I looked at the documentation which explicitly says that if there is a solution, I should get the same result from both. And I wouldn’t even be that bothered if one of them gave more or less correct solutions, since I only need one value of (k,m) for what I’m doing, but if I’m getting incorrect results in different cases then it’s a bit of a problem.

## plotting – Understanding how to forward results, computations & functions to inbuilt functions

I may be missing something obvious about the Mathematica language, but I am having trouble understanding something; so much so that I am not sure if the title of the question is appropriate (not specific enough?). I found these related questions but that does not seem to be the problem here.

My question is suppose I write a function:

``````Op(sys_, ip_) := OutputResponse(TransferFunctionModel(sys, s), ip, t);
``````

I can make it do useful computation as follows:

``````Op((s + 1)/(s^2 + 2 s + 1), Sin(t)) // InputForm
``````

returning:

``````{-(-1 + E^t*Cos(t) - E^t*Sin(t)) / (2*E^t)}
``````

What I want to do next is:

``````Plot(Op((s + 1)/(s^2 + 2 s + 1), Sin(t)), {t, 0, 10})
``````

but for some reason, this fails and I don’t understand why. I discovered that if I store the stuff returned by the call to `Op` in an intermediate value, then the plotting command works.

``````fluff = Op((s + 1)/(s^2 + 2 s + 1), Sin(t));
Plot(fluff, {t, 0, 10})
``````

I don’t understand why this works and the other doesn’t. How would I go about fixing the first case without using an intermediate value?

PHP runs same user as terminal user:
`echo shell_exec("id");` returns:

``````uid=1000(alien) gid=998(wheel) groups=998(wheel),108(vboxusers),150(wireshark)

Running `id` in terminal returns:

## probability or statistics – Intepreting the results of DistributionFitTest, and other alternatives in Mathematica 12.1

I have been playing with `DistributionFitTest` as a means of testing how normal some data sets I have. I’ve been working with some simulated data sets so I can try and understand what’s going on. From the documentation it seems `DistributionFitTest` returns a $$p$$-value by default, which according to the documentation

A small $$p$$-value suggests that it is unlikely that the data came from dist.

Firstly, how is “small” defined?

From my limited understanding of $$p$$-values, it seems that if the resultant $$p$$-value is $$< 0.05$$ then one can say it is unlikely that the data belongs to the proposed distribution. Again, from my understanding this $$0.05$$ threshold should be considered as a hard line, so $$p = 0.04999$$ should be rejected while $$p = 0.05000$$ is accepted.

As for my “simulations” I did a simple test to find out how $$p$$-values are distributed for multiple data sets which are generated from the dame distribution. I use the `"KolmogorovSmirnov"` option as the K-S test seems to be the standard approach used.

``````ManypValue =
Table[
NormalData = RandomVariate[NormalDistribution[0, 1], 1000];
pValue = DistributionFitTest[NormalData, NormalDistribution[[Mu], [Sigma]], "KolmogorovSmirnov"],
{i, 1, 512}
];

Histogram[ManypValue, "FreedmanDiaconis", "PDF",Frame->True, FrameLabel->{"p-Value","PDF"}]
``````

The result is a uniform or box distribution which goes between $$0$$ and $$1$$, so I understand this to mean that there is a $$5%$$ chance of a dataset which is normal being identified as non-normal — on the basis of this $$p>0.05$$ threshold:

Finally, are there any other methods in Mathematica as a means of testing whether data belongs to a distribution?
