            ReactJs App's mapped list of buttons from Json file only have the last value of json array
            Asked 2021-Jun-12 at 02:46

            I am making list of button that will lead to different YouTube videos on ReactJs page. The issue is that when I map the links from json file (which contains video links), all the buttons get the last link of the mapped array. I need a way that all the rendered buttons will get their respective links. My code is below, I am using react ModalVideo to show my YouTube video.



            Answered 2021-Jun-12 at 02:46

            Just some quick ideas looking at the minimal snippets available.

            1. let's not to render multiple ModalVideo component like above, move it out from the map.
            2. Use another state to keep track the change of the youtube videos' ID.

            Does it make sense to backpropagate a loss calculated from an earlier layer through the entire network?
            Asked 2021-Jun-09 at 10:56

            Suppose you have a neural network with 2 layers A and B. A gets the network input. A and B are consecutive (A's output is fed into B as input). Both A and B output predictions (prediction1 and prediction2) Picture of the described architecture You calculate a loss (loss1) directly after the first layer (A) with a target (target1). You also calculate a loss after the second layer (loss2) with its own target (target2).

            Does it make sense to use the sum of loss1 and loss2 as the error function and back propagate this loss through the entire network? If so, why is it "allowed" to back propagate loss1 through B even though it has nothing to do with it?

            This question is related to this question https://datascience.stackexchange.com/questions/37022/intuition-importance-of-intermediate-supervision-in-deep-learning but it does not answer my question sufficiently. In my case, A and B are unrelated modules. In the aforementioned question, A and B would be identical. The targets would be the same, too.

            (Additional information) The reason why I'm asking is that I'm trying to understand LCNN (https://github.com/zhou13/lcnn) from this paper. LCNN is made up of an Hourglass backbone, which then gets fed into MultiTask Learner (creates loss1), which in turn gets fed into a LineVectorizer Module (loss2). Both loss1 and loss2 are then summed up here and then back propagated through the entire network here.

            Even though I've visited several deep learning lectures, I didn't know this was "allowed" or makes sense to do. I would have expected to use two loss.backward(), one for each loss. Or is the pytorch computational graph doing something magical here? LCNN converges and outperforms other neural networks which try to solve the same task.

            Yes, It is "allowed" and also makes sense.

            From the question, I believe you have understood most of it so I'm not going to details about why this multi-loss architecture can be useful. I think the main part that has made you confused is why does "loss1" back-propagate through "B"? and the answer is: It doesn't. The fact is that loss1 is calculated using this formula:

            I am implementing a seminar application with twilio programmable video. The scenario can be described as following:

            1 host lectures n participants. The participants can participate only via audio but can see the hosts video. I accomplished that by simply unpublishing and disabling the videostreams of the participants:

            Rather than asking for access to the video and then disabling it afterwards, you should not ask for camera access in the first place.

            You can achieve this by changing the media constraints you send in to the connect method like this:

            Android Studio: Database search functions fine but unable to display all records via button
            Asked 2021-Jun-03 at 13:27

            Much like the title says. I have followed my class tutorials but chunks seem to be missing and it gets a bit confusing flicking between video lectures and pdf's when you're not too well versed in such.

            When the app is executed the user can search for a song by year, or display all records within the database. However, originally all records would display from clicking the search by year button instead of the display all button. The search function works as intended but the display all button I cannot seem to figure out, despite following my lecturer's tutorials.

            The first section of code is "MainActivity.java" and the second is "OpenDatabse.java"

            Asked 2021-May-24 at 06:53

            After going through some lectures on class and objects, what I have understood is that if a function is a part of a class then it can be accessed by object which is known as method and if a function is outside a class, then it can be accessed directly.

            So for example -

            There are 3 types of functions(methods) you can have inside an python class.

            1. Instance Method
            2. Class Method
            3. Static Method

            Here's a thing to see that what you have created the method named introduce inside room that is "Instance Method". Which takes object as self parameter meaning which can be accessed by Instance(object).

            You can also define a Class Method in following way.

            Why is it considered that availability zones do not provide High availability?
            Asked 2021-May-03 at 09:32

            I am new to the world of the cloud and trying to get my head around some confusion I have while watching foundational lectures on A cloud guru.

            I am going through Azure lectures where they explain the basic difference between regions and availability zones.

            Now according to MSDN documentation,

            Availability Zones is a high-availability offering that protects your applications and data from datacenter failures. Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking.

            Also, given that each availability zones have multiple data centers it should be all the more reason and intuitive to think that in contrast to regions, availability zones provide both Fault Tolerance and High Availability, but the lecture on Acloud Guru states otherwise,

            Also, if availability zones have multiple datacenters, does that imply that regions have 1 datacenter?



            Answered 2021-May-03 at 09:32

            So availability zones do offer a level of high availability, but there are a couple of things to be aware of. Firstly a region is a level up from an availability zone in the same sense that a geography is a level up from a region. However, not all regions have availability zones, eg the UK west region does not have availability zones but the UK south region does.

            From link 2 below:

            Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters [...] Availability Zones and their associated datacenters are designed such that if one zone is compromised, the services, capacity, and availability are supported by the other Availability Zones in the region.

            This means firstly, you need to choose a region that has availability zones to make use of them.

            Secondly, not all services or SKUs can make use of availability zones, eg standard app service cannot so if you want a highly available standard app service you’ll need to spread them across regions and use something like traffic manager or front door to load balance in front of them. On the other hand app service environments can be used with availability zones as can other services “out of the box”.

            Thirdly, in terms of high availability you might consider availability groups to not be sufficient on their own for your use case. Eg if you had a major outage or natural disaster in a region it could take out several availability zones so you may want to spread things over multiple regions (or even clouds).

            Also from the second link:

            To achieve comprehensive business continuity on Azure, build your application architecture using the combination of Availability Zones with Azure region pairs. You can synchronously replicate your applications and data using Availability Zones within an Azure region for high-availability and asynchronously replicate across Azure regions for disaster recovery protection.

            I would add to this that you can also achieve high availability (as oppose to just DR) by deploying across regions but it depends on the specific requirements of your system.

            Terminology and Info on geography, regions, availability zones, etc.

            Azure regions that have availability zones and Azure services that support availability zones.

            Running a task in a separate thread which shold be able to stop on request
            Asked 2021-Apr-26 at 13:53

            I am trying to design an infinite (or a user-defined length) loop that would be independent of my GUI process. I know how to start that loop in a separate thread, so the GUI process is not blocked. However, I would like to have a possibility to interrupt the loop at a press of a button. The complete scenario may look like this:

            GUI::startButton->myClass::runLoop... ---> starts a loop in a new thread

            GUI::stopButton->myClass::terminateLoop ---> should be able to interrupt the started loop

            The problem I have is figuring out how to provide the stop functionality. I am sure there is a way to achieve this in C++. I was looking at a number of multithreading related posts and articles, as well as some lectures on how to use async and futures. Most of the examples did not fit my intended use and/or were too complex for my current state of skills.

            As far as i know, there is no standard way to terminate a STL thread. And even if possible, this is not advisable since it can leave your application in an undefined state.

            It would be better to add a check to your MyClass::runLoop method that stops execution in a controlled way as soon as an external condition is fulfilled. This might, for example, be a control variable like this:
