            The problem

            I'm trying to find a way of using marble testing to test side efects with async pipes. I've created a simple POC in Stackblitz so you may test it for yourselves https://stackblitz.com/edit/angular-ivy-pzbtqx?file=src/app/app.component.spec.ts

            I'm using the result from a service method, which returns an Observable of either an object or null (see component file), and the *ngIf directive with an async pipe to either display or hide some html element depending wether the result from the method was an object or null (see html file).

            Now I would like to create a Unit Test for the aforementioned case using marble testing however when I use the cold observable as the return value from my mocked service. It is allways being interpreted as null (or to be more exact falsy) by the async pipe.

            Mancala program showing correct output but valgrind showing errors
            Asked 2022-Mar-18 at 16:36

            I had an assignment to replicate mancala. The rules of the game are slightly different from original, and are the following:

            The active player removes all stones from a pit on their side of the board and distributes them counter-clockwise around the board.

            Distribution includes the player's goal, but not the opponent's goal.

            If distribution ends in the player's goal, they take another turn.

            If distribution ends on the player's side, in a previously empty pit, the last stone and any stones immediately across the board are moved to active player's goal (and their turn ends).

            If a player's side of the board is empty (not including their goal), any remaining stones are collected by the opponent and the game is over.

            I failed the assignment a while back and I'm still trying to figure out why I'm wrong. The program has correct output but my school requires us to use a programming tool called valgrind and that's where the issue comes from.

            I have a function that could be considered long running (actually, it's multi-step where each step could be waiting for an external event like a response from a HTTP call).

            There's an invoker function to this which should return an observable that returns the updates to the original function. The original function MUST run whether or not the returned observable is subscribed to. Basically, it needs to return a hot observable.

            I do not think you can test this scenario with marbles, at least in a simple way.

            Marbles are a synchronous mechanism, while Promises are always asynchronous.

            Therefore, when your test executes the run method of TestScheduler it does it synchronously. The Promise though will be resolved later by the JS engine, so only later the update$ Subject will emit its values.

            This is the reason why the test says that it gets 0 notifications from update$ rather than the 4 it expects. The notifications from update$ will come after the assertion has been evaluated.

            If you want to test this scenario without marbles, you can do something like this

            The problem is that the scores of the two players are reset to 9 marbles at the top of each run of the inner while loop. So after Mr Bot makes a guess, and the scores are adjusted, the scores are then reset back to 9 each just before the player gets asked to make their guess.

            The outer while loop is broken when the player says they don't wish to play any more, the inner while loop is broken when the game currently in progress finishes.

            Resize ImageViews to fit and use full screen width in Android

            How can I fit these two (or more) marbles (ImageViews) to the full width of the Android screen?

            The full screen should be used all the time, regardless of if there are 1 or 12 marbles.
            Right now only 1½ marble fits, so some resize are needed!

            This is how you fit two (or more) marbles (ImageViews) within the Android display width:

            • Set width = 0dp for every marble (ImageView)
              android:layout_width="0dp"
            • Set imgMarble1's "Start" to "StartOf parent" and "End" to "StartOf imgMarble2"

              app:layout_constraintEnd_toStartOf="@+id/imgMarble2"

            Asked 2021-Dec-21 at 14:07

            I'm pretty deep into a combination of joins and subqueries which have ended up having a query result which looks like this: I'm not dealing with marbles at all, but I guess a way of explaining this would be to imagine a bag with blue and red marbles. Bag 1 contains both blue and red, (hence a result for true and false), Bag 2 also the same. Bag 3 only only contains blue marbles and no red ones, so there is only one entry which is true. And bag 4 contains only red ones so the value is false.

            What I'm trying to do is select all the IDs where they don't have a 'true' value. So in this case below, IDs 1,2 and 3 all have a row which has the value 'true', whereas IDs 4 and 5 only contains false(s) and no trues. So I want the query to return ID 4 and 5. These results are grouped by their IDs so I've been trying different HAVING clauses, trying to count where COUNT of trues = 0 for a specific idea but haven't had any success.

            The function you are looking for is BOOL_OR().

            Here explains as:

            If any value in a set is true, the BOOL_OR function returns true (t). If no value in a set is true, the function returns false (f).

            Install marbles

            Before you tackle the various instructions below decide what type of setup you really want. It is possible to skip the developer setup and get Marbles running with 2-3 brainless clicks. If you want a developer's setup, follow the instructions 0 - 4 below. By the end of it you will be a hyperledger fabric pro, and have the setup to develop an application of your own design. If you want to skip all of that and simply try marbles on a IBP (IBM Blockchain Platform) network then follow the Toolchain setup flow. If you really want to impress your friends, do both. If you already used the Toolchain setup then skip down to the Use Marbles section. If you are choosing the dev setup, then keep reading. The good news is marbles and the blockchain network can be setup for different configurations depending on your preference. The bad news is this makes the instructions complicated. If you are new to Hyperledger Fabric and want the simplest setup then follow the :lollipop: emoji. Whenever there are options and you must choose your own adventure, I'll drop a :lollipop: emoji on the option that is the simplest. This is the option for you.
            Follow these environment setup instructions to install Git, Go and Node.js.
            When you have finished come back to this tutorial. Start the next section "Download Marbles" below.
            We need to download marbles to your local system. Let’s do this with Git by cloning this repository. You will need to do this step even if you plan on hosting marbles in IBM Cloud.
            Open a command prompt/terminal and browse to your desired working directory
            Run the following command: git clone https://github.com/IBM-Blockchain/marbles.git --depth 1 cd marbles
            Great I'll meet you at step 2.
            OK, almost there! Now we need to get our marbles chaincode running. Remember the chaincode is a vital component that ultimately creates our marbles transactions on the ledger. It is GoLang code that needs to be installed on our peer, and then instantiated on a channel. The code is already written for you! We just need to get it running. There are two ways to do this.
            Option 1: Install and instantiate chaincode with your IBM Blockchain Service - instructions
            Option 2: :lollipop: Install and instantiate chaincode with the SDK locally - instructions

            Support

            The admin will interact with Marbles, our Node.js application, in their browser.This client side JS code will open a websocket to the backend Node.js application. The client JS will send messages to the backend when the admin interacts with the site.Reading or writing the ledger is known as a proposal. This proposal is built by Marbles (via the SDK) and then sent to a blockchain peer.The peer will communicate to its Marbles chaincode container. The chaincode will run/simulate the transaction. If there are no issues it will endorse the transaction and send it back to our Marbles application.Marbles (via the SDK) will then send the endorsed proposal to the ordering service. The orderer will package many proposals from the whole network into a block. Then it will broadcast the new block to peers in the network.Finally the peer will validate the block and write it to its ledger.
