QUESTION
I have a loop to create a map with Folium, the input is a database "s", but it only reads the first line. Something is stopping the loop.
Maybe it's an Indentation problem.
The code works as follows, first we check if we have a downloaded photo in the directory, if it is correct, we use this photo for the Folium popup and add feature. If we don't have a photo, we scrape it, download the photo to the directory, use it for the popup and add a feature.

yes, the two returns, because your code is :
QUESTION
99% of all answers is about case sensitive value. What I am looking for is a code to delete the row if one of these keywords found in column A so regardless if it is capital letter or small letter
keywords: tfg, tfb, Steam, Roast
...ANSWER
Answered 2020-Sep-21 at 01:05One way. Work from the bottom upwards because if you go top-down, row deletion will corrupt the iteration.
QUESTION
I have read several questions with similar errors, but I can't figure out my problem. I have checked that I am not accessing anything after deleting it, or trying to delete it twice.
The class Node and List are implemented by myself, but I have used them in several exercises before this one, so I don't think the problem is with the class implementaiton. Here is the code and the error given by valgrind. By the way, the program apparently works.
...ANSWER
Answered 2020-Jun-10 at 15:33Your List class lacks a valid copy constructor and assignment operator but you are copying List objects, for instance when you call sumNotReverse.
This will result in a double free or a use after free, which is presumably the problem valgrind is complaining about.
See here for more details What is The Rule of Three?, or consult your favourite C++ book. Any decent C++ book is going to cover this topic.
QUESTION
I have a pod running a Flask app in python, which is listening in port 8083. If I access the app from inside the pod, it works:
...ANSWER
Answered 2020-Apr-16 at 09:17Usually this is the case when the python app does only use the loopback interface to listen for connections. Make sure that the listening interface (host) is not 127.0.0.1 but 0.0.0.0
QUESTION
I'm developing an application that, in summary, uses MQTT to send sensor values to a broker to later visualize that data in a dashboard web application. I have five microcontrollers connected to the broker and I've set up a server certificate for the broker and client certificates for each microcontroller.
The problem is that, in the mosquitto.conf file I require the use of client certificates for the clients that want to connect, so if I want to subscribe to a topic from my web application I need a client certificate. I'm trying to find the right approach for accomplishing this, but it seems that having a certificate and key in a machine you cannot control is a big security risk.
It would be ideal if someone knew a way of tweaking the mosquitto configuration file or establish some kind of exception (maybe similar to ACL's) to only require client certificates for certain clients (in my case, the microcontrollers) and use username@password for the others (web clients). Is it possible to do such a thing?
Any help would be much appreciated
EDIT (regarding @hardillb 's answer)
My mosquitto.conf:
...ANSWER
Answered 2020-Apr-02 at 10:17Mosquitto allows you to have multiple listeners per broker that all share the same topic space.
Listeners can support native MQTT, MQTT over Websockets (including Websockets over TLS) and MQTT over TLS.
It also has the per_listener_settings option which allows you to specify different authentication options for different listeners. This option was added in mosquitto version 1.5.
So in this case, you can create a MQTT over TLS listener and use client certificates to authenticate those users (devices) and a MQTT over Websocket listener that will use username/password authentication.
e.g. something like this (but probably using a authentication plugin rather than acl/password files)
QUESTION
I am making a web with information from a MySQL database and I want pictures to appear after clicking a buttom.
...ANSWER
Answered 2020-Feb-24 at 13:38first a little advice, separate php, javascript and html. Together it is difficult to read and maintain. Otherwise you create a function at each pass of the loop. It doesn't bother me that nothing works like that. Try it like this:
Send the id of your image as a parameter to the function. A single function, which will be after the loop.

Trying to find a few examples on this, but all I seem to find are AngularJs examples.
Is it possible to enable my textbox when the checkbox in the same row is checked, without binding the checkbox to a boolean value, and binding that value to my `textbox', or without the need to write some Javascript?
ANSWER
Answered 2019-Oct-22 at 16:10You can bind the disabled property of the text input to the checkbox state with the help of a template reference variable. In order for the binding to work, the ngModel directive should also be applied to the checkbox.

I am currently working on a MySQL query. When it already delivers the correct needed data, I figured out that it needed to be converted to CodeIgniter syntax for me to be able to use it in a custom model in GroceryCRUD. I tried manually inputting all the select, join and where values to every suited statement

QUESTION
I'm working on a Java project with maven and I'm trying to generate the jar file. I'm using mvn-jar-plugin and mvn-dependency-plugin to try to include all the required libraries. Here's my pom.xml:
...ANSWER
Answered 2019-Jun-24 at 23:02It depends on how GestorProblema1maquina.jar was built. Does GestorProblema1maquina.jar contain the 3rd party jar with dominio/Instancia class, as in, is it a fat jar / uber jar?
If it is built using maven assembly plugin in a way that it includes all of its dependencies, you should not run into this at runtime.
There are 2 choices
- Use mvn install and make GestorProblema1maquina.jar available in the repository.
- [link] https://maven.apache.org/plugins/maven-dependency-plugin/copy-dependencies-mojo.html says that the dependecnies are copied from a repository.
Also it states "The scopes being interpreted are the scopes as Maven sees them, not as specified in the pom" , so your configuration for the plugin may need explicit includes for the 3rd party system scope jar dependency to be included in the eventual jar.
