kandi X-RAY | Hanno Summary
Hanno is an asynchronous event loop system for writing real-time applications in PHP. Unlike some similar systems, it is based around generators, avoiding the need for callbacks and greatly simplifying both reading and writing code. As it uses generators, it requires at least PHP 5.5. The name comes from the Japanese verb for to react, 反応する (Han’nō suru), a reference to the use of reactors and a nod to [ReactPHP] Because the Japanese word the name came from is pronounced Han’nō, you actually ought to pronounce "Hanno" with two separate n sounds like "Han’no", but in practise everyone (including myself) is just going to say "Hanno" (/ˈhæ.noʊ/).

QUESTION
I would like to check if the text of a variable contains some geographical reference. I have created a dictionary with all the municipalities I'm interested in. My goal would be to have a dummy variable capturing whether the text of the variable includes any word included in the dictionary. Can you help me with that? I know it isprobably very easy but I'm struggling to do it.
This is my MWE
...ANSWER
Answered 2021-Jun-14 at 08:34You don't need to create your dictionary from the corpus - instead, create a single dictionary entry for your locality list, and look that up to generate a count of each locality. You can then count them by compiling the dfm, and then converting the feature of that dictionary key into a logical to get the vector you want.

I'm working with the movie DB API (https://developers.themoviedb.org/3/genres/get-movie-list this one) and I print with VUE the results of my call in my page. The API provides me all data I need to have to achieve my goal, that is this
As you can see, under the show name there are the genres associated with that name. Let's take for example the object I obtain when the API gives me A-Team

QUESTION
I am making an application with Laravel 8 and Livewire.
In my reportResidui.blade.php view I have integrated a livewire component called report-residui-header-filter and which I use to filter (this component works fine).
The problem occurs when I perform the query, I need to filter from a table going to group the data for the field anagrafica_soggetto.codiceFiscale with a where clause where('importoResiduo', '>', '0').
But when I run the query I get the following error and I don't understand what it comes from, since removing the groupBy clause works.
Anyone have any suggestions or advice?
Error:
...ANSWER
Answered 2021-Apr-20 at 09:56you are trying to group by anagrafica_soggetto.codiceFiscale but you have many joins in your query so you have to explicitly tell MySQL how to group the other selected items in your select list.
The solution is to group by at least 1 field from every table you are joining.

I made 3 different packages with classes in them. One package is for simple fractions and another is for arrays of fractions. The smaller one is for implementing math functions mcm and MCD.

QUESTION
I'm trying to develop an image classifier with Keras, I followed the tutorial on the page: https://www.tensorflow.org/tutorials/images/classification?hl=en
Still using the flower dataset that the tutorial provides, I tried to test the model by making a prediction with a photo of a goat. The result was that the prediction saw that the goat photo belongs to the class of daisies at 70%. I think this is impossible considering also that there are no daisies in the photo of the goat.
This is the code I used :
...ANSWER
Answered 2020-Nov-20 at 18:46Since your model has been trained on a closed set of images, it will take any image of another kind to fit the schemes it learned and often it will succeed. In the end the output probability is nothing else that the probability given certain shapes combinations and colors in an image, not the abstract concept that you expect as an output (for understanding more what a neural network actually sees, you can read this article among others: https://www.kdnuggets.com/2016/06/peeking-inside-convolutional-neural-networks.html)
The solution to your problem is therefore to teach your neural network another class, a suplemental one, consisting of various generic images which are not your target. You can get the images to feed into such a class from ImageNet (http://image-net.org/), for instance. In this way you will have an adversarial output that will fire up when the images you are providing are not among the targets you expect.
Techinically speaking, in relation to the code you have provided, you just have to create a further directory in your training and validation directories, a directory containing mixed images for your extra class "other".

can anyone help me figure out what's wrong with the code? links not working, if you click on it nothing happens. I thought I left some tags open but I checked with https://validator.w3.org and there are no such errors! What could be the problem?
I have seen the other questions and answers related to this topic but they did not help me.

ANSWER
Answered 2020-Aug-26 at 07:24It's because of the z-index in your css. Links with negative z-index are unclickable, its better to remove the z-index: -1 from your *-selector.
Or you can add an additional selector for the -Tags to your style:
QUESTION
I need a method to order a Map of generic object by a generic attribute of the object. I tried the code below, similar to other example I found on StackOverFlow, but I didn't find any example with a generic attribute. I'm not expert of lamda, so for me it is hard to understand clearly some logics.
I get error on compareTo; Ntebeans says me:
"cannot find symbol symbol: method compareTo(CAP#1) location: class Object where CAP#1 is a fresh type-variable: CAP#1 extends Object from capture of ?"
Example:
- I have a object 'car' with attribute 'name'
- I have an Hashmap, containing items: key 1, object with name=Ford --- key 2, object with name=Audi --- key 3, object with name=Fiat
- The first element of the map has key 1, the second has key 2, the third has key 3
- I would like to have in output an Arraylist where: - The first element is object 'Audi', the second is object 'Fiat', the third is object 'Ford', so to have the 3 names sorted.
In order to invoke this method I would use for example:

ANSWER
Answered 2020-Jul-03 at 17:40When you make requests like these you should make a condition to test the results so you can see what is going on. I can't be positive that my way of testing the error code is exactly how you should do it, but it is definitely in the ballpark.

Install Hanno
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
