ng-store | FireBase shopping cart project built for front and admin | Dashboard library

Starting from a minimal Vue2+Vuex typescript app created with @vue/cli. I want to ensure references to this.$store.state within a component are of the correct type declared by the Vuex store and its modules.

How can I achieve this? Without intervention, all references to this.$store resolve to Store.

In this commit I changed the default src/store/index.ts created by @vue/cli to introduce a message property in the store...

I’ve been developing a dash app that uses a long_callback, and for development I’ve been using a diskcache backend for my long_callback_manager, as recommended by the guide I found here: https://dash.plotly.com/long-callbacks

When I tried running my app using gunicorn, it failed to start because of something apparently wrong with diskcache. As such, I decided to switch to a celery/redis backend since that’s recommended for production anyway.

I got a redis server running (responds properly to redis-cli ping with PONG), and then started the app again. This time it started up fine, and all of the normal callbacks work, but the long_callback does not work.

Details:

• The page more or less hangs, with the page title flashing between the normal title and the Updating... title, indicating that the app thinks it’s “waiting” for a response/update from the long_callback.
• The values set by the running argument of the long_callback are set to their starting value, indicating that the app recognizes that the long_callback ought to run.
• By placing a print statement as the first line within the long_callback function and seeing that it does not print, I’ve determined that the function never starts.
• The failure happens both with gunicorn and without gunicorn.

These details all point to the problem being the celery/redis backend. No errors are shown, neither on the client/browser nor on the server’s stdout/sterr.

How do I get a celery/redis backend working?

UPDATE: After realizing that the __name__ variable is being used and that its value changes depending on the file from which it is referenced, I've also tried moving the code which creates celery_app and LONG_CALLBACK_MANAGER into app.py, to no avail. The exact same thing happens.

In an attempt to profile & optimize a caching algorithm, I got stuck at something I don't understand.

Here is the hot-spot of the perf's report (in Ubuntu 18.04 LTS and g++ 7.5):

How does just a "mov" operatiaon between rax and rdx registers cause ~30% of total run-time of program? It's not a register-heavy program (an LRU-cache approximation algorithm that is doing ~50million lookups per second at max and this is around 400MB/s throughput(and certainly not faster than RAM for bigger key-value pairs) which should not be related to register bandwidth at all)

Test system's CPU is FX8150 and has 1 channel memory attached with 9GB/s bandwidth which is way higher than this single-thread cache can achieve for just "int" key + "int" value pairs. So I guess it should be safe to leave RAM out of this problem. Also the mov instruction looks like a part of std::unordered_map's lookup operations. I know this CPU is old but not really ancient-old so perhaps compiler is not using the right instruction here due to some "support for old CPU" issue?

Source code to reproduce the hot-spot:

Is it possible to create a materialized view from a consumer, without really writing the logic for it? As my data in kafka topic can be materialized without any transformations

I'm struggling to configure Spring Cloud Stream correctly for Kafka-Streams to use SSL with a trust-store and key-store.

In my application i have multiple Streams running, the SSL configuration should be the same for all of them.

The application looks like this:

Stream1: Topic1 > Topic2

Stream2: Topic2 > Topic4 Topic3

Stream3: Topic4 > Topic5

I use the latest Spring-Cloud Stream Framework with Kafka-Streams, with Avro Models. I can configure the schema-registry.

I have recently upgraded to the latest version of asp.net boilerplate. I have managed to fix all issues with the upgrade.

The only issue left is that my custom repositories are no longer working.

The error I am getting is "Context does not exist in the current context" I have followed the tutorial for adding custom repositories but I am not sure if I have missed something in the upgrade. The error is in the helpers provided in the custom repositories tutorial.

I am trying to deduplicate the records using input topic as KTable and sinking them to output topic. But the KTable is still sinking the duplicate records to the output topic. Not sure where am I going wrong.

Here is my application.yml

I have searched for similar questions, but they are old.

I am trying to optimize my work by using a stored procedure to retrieve all related tables to one to avoid multiple queries. I want to use this kind of stored procedure which returns multiple tables as JSON and output parameters, but I am new to ASP.NET Core MVC with EF. Could someone guide me in the right direction? How can I read that output parameter and convert them to objects? it's worth mentioning that I want to use tables for dropLists.

The main table has some columns which are mentioning to some tables. I want to have those table values and show them in some dropdowns or checkboxes.
