I'm using Minio Server to handle files in my nodejs API, basically to emulate s3 locally. I generated Presigned Url to upload images directly.
Presign Url Generation works fine but when I upload my file from Postman the file it gives me this error:

QUESTION
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.

Solution:QUESTION
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.
Why would valgrind give me this error

QUESTION
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 have tried the following approach but, cannot get it to work:
...ANSWER
Answered 2022-Mar-18 at 11:08I 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

On Upgrading, to angular 13, My build step on pipeline is failing. My initial version was 11, on upgrading to 12 the build worked fine but on upgrading from 12 to 13, it started giving me this error on pipeline. The build is running fine on local but failing on pipeline.
I have also added the package.json file code and dependencies and also added the image that displays error.
...ANSWER
Answered 2022-Mar-03 at 14:48I was facing the same issue which is why I stumbled across this post.
My issue was I was using the wrong node version. I faced a similar issue after upgrading to Angular 13 but I was using node version v14.2.0.
I changed the node version to v14.15.0 and it worked.
nvm use v14.15.0

QUESTION
Everything is correct in my code, but after running when the 2nd loop is executed 2 or times the value picked by system is something else and the value (added/subtracted) afterwards is something else..even in both case the variable used is same....
...ANSWER
Answered 2022-Feb-20 at 11:47The 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.
Move the lines that reset P_1 and P_2 so that they are only inside the outer while loop. In other words, replace
QUESTION
Apologies for lack of a reproducible example as I'm not too sure how to code this.
Let's say I have four groups: red, yellow, green, and blue.
I have fifteen marbles to distribute to each group, with a constraint that each group must have at least two marbles. How can I get all possible combinations that can be allotted to each group? My desired end result is a data frame along the following lines, where the number represents the number of marbles allocated to that group:

QUESTION
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!
In conclusion I would like to be able to add as many ImageViews as needed and they should automagically be resized to fit within but also use the whole Android display width...
My XML-code:
...ANSWER
Answered 2022-Jan-28 at 08:39Thanks @FilipeOliveira for your help:
From his comments above...
This is how you fit two (or more) marbles (ImageViews) within the Android display width:
- Set
width = 0dpfor every marble (ImageView)
android:layout_width="0dp" - Set imgMarble1's "Start" to "StartOf parent" and "End" to "StartOf imgMarble2"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toStartOf="@+id/imgMarble2" - Set imgMarble2's "Start" to "EndOf imgMarble1" and "End" to "EndOf Parent"
app:layout_constraintStart_toEndOf="@+id/imgMarble1"
app:layout_constraintEnd_toEndOf="parent"
"This will create a chain and the width will be auto resize based on screen width."

QUESTION
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.
Input: this table (which is a result of a bigger query)

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
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
