Below is what I get when trying to install angular globally. Not sure why it is trying to install from git...

C:\D\Ts.NetAngular> npm install -g angular/cli info: please complete authentication in your browser...-session 3cdebc65d33fb371 npm ERR! Error while executing: npm ERR! C:\Program Files\Git\cmd\git.EXE ls-remote -h -t ssh://git@github.com/angular/cli.git npm ERR! npm ERR!

C:\Users...\AppData\Roaming\npm-cache_logs\2020-12-08T23_50_51_414Z-debug.log

And when I open the gitlog file, I see the below...

We have a .NET ASP Web form application. Currently we use TeamCity for the CI part. Deployment part is manual. We take the build artifact generated by TeamCity and deploy the artifact manually.

Now we will be using Azure DevOps for complete CICD process. During the POC we have been able to successfully build and deploy the application in IIS. I am new to the azure pipeline and doing POCs to learn it.

In TeamCity, against each build the generated build artifacts are available. So we can easily refer to any specific build and get the build artifact for that specific build. This is useful in case of rollback. We take the last successfully build artifacts and deploy the same in case of any error.

But in Azure is there any build artifacts repository where we can get the all the build artifacts for all the builds of that pipeline ? There is a section "Artifacts" but as per my knowledge this is for publishing as packages across feeds.

Now I have come across JFrog artifact repository https://jfrog.com/artifactory/. But no nothing about this. Need to go through.

Anyone can please let me know , in azure pipelines , where I can get all the build artifacts against all the builds in a pipeline. Is it available against each run in the pipeline or I need to configure it somehow ?

In any release failure , I need to rollback to the last successful deployed artifact version.

Thanks in advance for any guidance on this.

When I run rasa init --no-prompt I am getting the above error. I am not able to debug the cause for this error, Above are the commands I have used to install Rasa.

pip3 install rasa

pip3 install --upgrade tensorflow rasa

pip3 install --upgrade tensorflow-addons rasa

pip install --upgrade pip

pip3 install --upgrade tensorflow-addons rasa --use-feature=2020-resolver

Above are my details of the versions used

Rasa version: 1.10.10

Python version: 3.6.9

Operating system Ubuntu 18.04.4 64 bit

tensorflow 2.3.0

tensorflow-addons<0.8.0,>=0.7.1

I am getting the above error, my virtual env is activated.

I'm working on an Ionic application.
On the one hand I have an auth basic form in which people fill in their username and password. On the other hand I'd like to implement authentification with JSON Web Tokens and Node JS.
The workflow would be this one : as soon as a user fills in his credentials, they will be sent with a POST request. If these credentials are correct, the user can access to the application and gets an access token as a response.

The thing is that I'm a little bit lost with all that concepts. I built a form and sent informations with a POST request. I managed to create some APIs with Node JS and that's ok. I see how to build a authentified webservice too (e.g : https://github.com/jkasun/stack-abuse-express-jwt/blob/master/auth.js).
But I concretely don't understand the links between the html form and the authorisation check part..
To be clearer, how is it possible to make the html part and the Node JS scripts communicate together ?

Before posting that question I made many researches and found many stuff on building an authentified API. But there was very few advice on how to make it communicate with the client part (I mean the form), which is what I have to do.
If anyone has any ressources (document, Github examples..) on that, I'll greatly appreciate. But I would be very happy too if someone try to make me understand these concepts. I guess I have to improve my knowledge on all that so that I could test some POCs.

Many thanks in advance !

Context : I'm trying to run through a Docker container a Plotly-Dash/Flask based web application that connects to a Redis server that runs inside a second container. I'm trying to achieve something close to this example, only with my application.

So I have in my project folder :

1. The main application videoblender.py inside a package named apps
2. A dockerfile named Dockerfile
3. A docker-compose file named docker-compose

Problem : When I run my program through the command docker-compose up --build, the building succeed then I get an error saying the following [Errno -3] Temporary failure in name resolution.

What I've tried : I've tried to run the example from the link above which a simplified example of what I'm trying to achieve, and it worked. So the problem seem to be somewhere in my specific implementation of it.

My code works fine outside of containers, with a local redis server running at localhost:6379. When I run it locally, I assign to the host parameter of the Redis object constructor the value 0.0.0.0, or localhost, it doesn't matter which one.

Additional informations and files :

docker-compose.yml :

Using Spring Boot Web & Data JPA (2.3.1) with QueryDSL with PostgreSQL 11, we are trying to implement a custom search for a UI table on an entity with two @ManyToOne child entities. The idea is to be able to provide a single search input field and search for that string (like or contains ignore case) across multiple String fields across the entities' fields and also provide paging. During UI POCs, we were originally pulling the entire list and having the web UI provide this exact search functionality but that will not be sustainable in the future.

My original thought was something to this effect:

I have two tables both billing data from GCP in two different regions. I want to insert one table into the other. Both tables are partitioned by day, and the larger one is being written to by GCP for billing exports, which is why I want to insert the data into the larger table.

I am attempting the following:

1. Export the smaller table to Google Cloud Storage (GCS) so it can be imported into the other region.
2. Import the table from GCS into Big Query.
3. Use Big Query SQL to run INSERT INTO dataset.big_billing_table SELECT * FROM dataset.small_billing_table

However, I am getting a lot of issues as it won't just let me insert (as there are repeated fields in the schema etc). An example of the dataset can be found here https://bigquery.cloud.google.com/table/data-analytics-pocs:public.gcp_billing_export_v1_EXAMPL_E0XD3A_DB33F1

Thanks :)

## Update ##

So the issue was exporting and importing the data with the Avro format and using the auto-detect schema when importing the table back in (Timestamps were getting confused with integer types).

Export the small table in JSON format to GCS, use GCS to do the regional transfer of the files and then import the JSON file into a Bigquery table and DONT use schema auto detect (e.g specify the schema manually). Then you can use INSERT INTO no problems etc.

I have Spark set up in standalone mode on a single node with 2 cores and 16GB of RAM to make some rough POCs.
I want to load data from a SQL source using val df = spark.read.format('jdbc')...option('numPartitions',n).load(). When I tried to measure the time taken to read a table for different numPartitions values by calling a df.rdd.count, I saw the the time was the same regardless of the value I gave. I also noticed one the context web UI that the number of Active executors was 1, even though I gave SPARK_WORKER_INSTANCES=2 and SPARK_WORKER_CORES=1in my spark_env.sh file.

I have 2 questions:
Do the numPartitions actually created depend on the number of executors?
How do I start spark-shell with multiple executors in my current setup?

Thanks!

I am totally new to C#, I want to read a CSV file line by line and write to another CSV file while writing I need to skip the first 4 lines, Can anyone help me with this?

Thanks in advance.

Below is the code I tried.
