QUESTION
I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.
I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.
Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.

I'm struggling to use the Micronaut HTTPClient for multiple calls to a third-party REST service without receiving a io.micronaut.http.client.exceptions.ReadTimeoutException
To remove the third-party dependency, the problem can be reproduced using a simple Micronaut app calling it's own service.
Example Controller:
...ANSWER
Answered 2021-Jun-15 at 09:51If this isn't going to throw an exception then I don't know what is going to.
This is caused by using blocking
code within Netty's event loop
.
The code over here is making a blocking request 20 times in a row which cause the machine to break. I don't know what data is coming from the client but I would never recommend to do it in this manner.
QUESTION
This question is related to Azure MSIX Build and Package task only has Release and Debug configurations
We have a WinForms project that has an MSIX installer. Manually, we can successfully create
- An MSIXBUNDLE and deploy it to Kudu
- An MSIX and deploy it to an Azure VM through a VHDX. We have manually convert the MSIX to a VHDX first
We are now trying to automate the build and release process to create the VHDX. However, we are getting a blank screen when the VHDX is mounted using a process that we have already validated. The only thing different is the build method (i.e., MSBuild versus VS Publish).
How do we create a working VHDX in Azure CI Build Pipeline?
Below is the YAML.
...ANSWER
Answered 2021-Jun-15 at 14:26Actually, there is nothing wrong with the YAML. The problem was a delay in the virtual machine loading the VHDX. In other words, wait about 5 minutes once the VHDX is mounted before trying to run the application. I am leaving this here in case anyone else runs into this issue

QUESTION
I am trying to run a simple parallel program on a SLURM cluster (4x raspberry Pi 3) but I have no success. I have been reading about it, but I just cannot get it to work. The problem is as follows:
I have a Python program named remove_duplicates_in_scraped_data.py. This program is executed on a single node (node=1xraspberry pi) and inside the program there is a multiprocessing loop section that looks something like:
...ANSWER
Answered 2021-Jun-15 at 06:17Pythons multiprocessing package is limited to shared memory parallelization. It spawns new processes that all have access to the main memory of a single machine.
You cannot simply scale out such a software onto multiple nodes. As the different machines do not have a shared memory that they can access.
To run your program on multiple nodes at once, you should have a look into MPI (Message Passing Interface). There is also a python package for that.
Depending on your task, it may also be suitable to run the program 4 times (so one job per node) and have it work on a subset of the data. It is often the simpler approach, but not always possible.
QUESTION
I'm running the below sqlpackage
command against my sqlserver
:
ANSWER
Answered 2021-Jun-15 at 12:05I would recommend using /action:Script
(see here) to see which actions it will perform, most likely this will give you some clue as to which flags should be set/cleared.
-- Edit
According to this old answer you can disable deploying the database properties when designing the .dacpac.
If you want to override this behaviour when publishing the .dacpac, you should probably use the ScriptDatabaseOptions
property - see the whole list of switches here.
QUESTION
I have users in a Cognito user pool, some of whom are in an Administrators
group. These administrators need to be allowed to read/write to a specific S3 bucket, and other users must not.
To achieve this, I assigned a role to the Administrators
group which looked like this:
ANSWER
Answered 2021-Jun-15 at 12:03The solution lies in the federated identity pool's settings.
By default the identity pool will provide the IAM role that it's configured with. In other words, one of either the "unauthenticated role" or the "authenticated role" that it's set up with.
But it can be told instead to provide a role specified by the authentication provider. That's what will solve the problem here.
- In the AWS console, in Cognito, open the relevant identity pool.
- Click "Edit identity pool" (top right)
- Expand "Authentication Providers"
- Under Authenticated Role Selection, choose "Choose role from token".
That will allow Cognito to specify its own roles, and you will find that the users get the privileges of their group.

ANSWER
Answered 2021-Jun-15 at 09:18I would start with running sp_who2
on the database server to see if sqlpackage
has made a connection to it, and if it's blocking on the server somewhere.
If so, you can further investigate with the SQL Server Profiler (can be found in the Tools menu of SQL Server Management Studio)

You've passed the result of the called function to the QueuePool
object as the first argument instead of the function itself. Remove the parenthesis to solve the issue:
