QUESTION
I've come across an issue of trying to fade the edges of the background image of a div so that it looks like it's blending with the background image of the full site (so the background image applied to the body).
...ANSWER
Answered 2021-Jun-16 at 02:49You can use the background as gradient where the edges are rgba(0,0,0,0). This way it will smoothly blend with background. But this will not work for images. For images You will have to a div of background color and rgba(0,0,0,0) in gradient with color facing outward.
QUESTION
I am having trouble tracking down documentation on this, so hoping someone knows as I am not able to get application insights to capture telemetry on starttrackevent and stopstrackevent across pages. This is an asp.net mvc application, so SPA is not in play here.
I am worried I may be doing something incorrectly, however the likely case is it doesn't support it.
Flow:
- user hits site for the first time
- user does action that triggers startTrackEvent("eventName");
- user navigates to a new page
- user does action that triggers stopTrackEvent("eventName");
-- from the appInsights readme https://github.com/microsoft/ApplicationInsights-JS/blob/master/README.md
appInsights.startTrackEvent("event");
appInsights.stopTrackEvent("event", null, {customProp1: "some value"});
ANSWER
Answered 2021-Jun-15 at 22:35Not per documentation, but via testing, can confirm that when a new page loads, appInsights will not persist start/stoptrackevent.

QUESTION
How can I stretch my subview across 100% width of its parent, minus 20px margin on each side? In other words, I need it to fill the width of the parent, with 20px open on each side.
I know in React-Native I can use width: '80%' to make my subview's width relative to that of its parent, but then it's not always precisely 20px on the sides. I also know that I can use alignSelf: 'stretch', however that is not working for me - it has unexpected / unreliable results. I don't want to use Dimensions, as the parent will not always be the device's screen, so Dimensions.get('window').width is inadequate for this problem.
What other options do I have?
...ANSWER
Answered 2021-Jun-15 at 16:01Use nested View. You can try here: https://snack.expo.io/@vasylnahuliak/stackoverflow-67989491

QUESTION
I have an Aurora Serverless instance which has data loaded across 3 tables (mixture of standard and jsonb data types). We currently use traditional views where some of the deeply nested elements are surfaced along with other columns for aggregations and such.
We have two materialized views that we'd like to send to Redshift. Both the Aurora Postgres and Redshift are in Glue Catalog and while I can see Postgres views as a selectable table, the crawler does not pick up the materialized views.
Currently exploring two options to get the data to redshift.
- Output to parquet and use copy to load
- Point the Materialized view to jdbc sink specifying redshift.
Wanted recommendations on what might be most efficient approach if anyone has done a similar use case.
Questions:
- In option 1, would I be able to handle incremental loads?
- Is bookmarking supported for JDBC (Aurora Postgres) to JDBC (Redshift) transactions even if through Glue?
- Is there a better way (other than the options I am considering) to move the data from Aurora Postgres Serverless (10.14) to Redshift.
Thanks in advance for any guidance provided.
...ANSWER
Answered 2021-Jun-15 at 13:51Went with option 2. The Redshift Copy/Load process writes csv with manifest to S3 in any case so duplicating that is pointless.
Regarding the Questions:
N/A
Job Bookmarking does work. There is some gotchas though - ensure Connections both to RDS and Redshift are present in Glue Pyspark job, IAM self ref rules are in place and to identify a row that is unique [I chose the primary key of underlying table as an additional column in my materialized view] to use as the bookmark.
Using the primary key of core table may buy efficiencies in pruning materialized views during maintenance cycles. Just retrieve latest bookmark from cli using
aws glue get-job-bookmark --job-name yourjobnameand then just that in the where clause of the mv aswhere id >= idinbookmarkconn = glueContext.extract_jdbc_conf("yourGlueCatalogdBConnection")connection_options_source = { "url": conn['url'] + "/yourdB", "dbtable": "table in dB", "user": conn['user'], "password": conn['password'], "jobBookmarkKeys":["unique identifier from source table"], "jobBookmarkKeysSortOrder":"asc"}
datasource0 = glueContext.create_dynamic_frame.from_options(connection_type="postgresql", connection_options=connection_options_source, transformation_ctx="datasource0")
That's all, folks
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
This morning I created an MSTest project in C#, and for one of the JSON resources, Visual Studio is showing this warning:
...ANSWER
Answered 2021-Feb-02 at 17:38Apparently all you have to do is to close out the file. It seems to only show when the file is opened.
Perhaps a later version of Visual Studio can make this warning behave more consistently with a standard warning in VS. Really it behaves very much like a refactoring / code cleanup suggestion (which commonly has a grey, squiggly line), rather than an actual warning. It's like it's just been mislabeled in development or whatever. However the good thing is that as long as the file is closed, it doesn't pollute the build or the errors window with warning messages.
QUESTION
So I am relatively new to programming, and I have been working on this task app, where I want to save the data such as task name and more, given by the user. I am trying to accomplish this using Room. Now, initially, when I tried to do it, the app would crash since I was doing everything on the main thread probably. So, after a little research, I came to AsyncTask, but that is outdated. Now finally I have come across the Executer. I created a class for it, but I am a little unsure as to how I can implement it in my app. This is what I did :
