kandi X-RAY | ponder Summary
Ponder is a C++ multi-purpose reflection library. It provides an abstraction for most of the high-level concepts of C++: classes, enumerations, functions, properties. C++1x supplies better support for compile-time reflection. Runtime reflection involves baking compile-time reflection into the executable so this can be used at runtime. Ponder presents a simple API for baking your objects so that they can be used at runtime. The baking can also, optionally, userdata and support for Lua scripting.

How do I handle the post action as layouts dont have a codefile?

Why isn't my image showing up with the url I'm using? The url is valid and I used the same method to insert other images and it worked. First code is the url that isn't showing up and the other one are the images that are showing up.

QUESTION
I've been pondering the best way to achieve this outcome for some time and have had success really tweaking my display templates and JS, but it's not scalable.
I have an observableArray, ContentGrid[], each item in the array has multiple objects including an object Taxonomies{} which contains objects Product & Docs. Both Product and Docs contain an array of items matching their classification, for example Product contains [ProductA] and Docs:[Photos].
I'd like to be able to group results by Product A, Product B, Product C, etc, however, I can't seem to find the right syntax to make this possible.
...ANSWER
Answered 2022-Feb-15 at 16:02You can use a pureComputed
that loops over the ContentGrid
array to create a group per unique product.
The example below shows:
- Create a
Map
to hold the groups. Its keys refer to a product and its values will be parts of your grid (i.e. partialContentGrid
s) - Iterate over the rows of the grid using
for ... of
- Iterate over all products in the row using
for ... of
- Ensure there's an empty array (= content grid) in the
Map
- Ensure this row gets logged in this product's group
To make it easier to render the groups to the UI, I transform the Map
instance in to an array of viewmodels. Each group gets a model with a
title
referring to the productrows
referring to the parts of the grid that matched this product.
As you can see this grouping will duplicate rows that have multiple products. If you want to implement a different grouping strategy, you'll likely want to update the inner loop.

...ANSWER
Answered 2022-Jan-21 at 16:32I don't think there is a safe and supported way to do that (without catalog modifications). Fortunately, there is nothing special about sequences that would make dropping them a problem. So take a short down time and:
remove the default value that uses the identity sequence
record the current value of the sequence
drop the table
create a new sequence with an appropriate
START
valueuse the new sequence to set new default values
If you want an identity column, you should define it on the partitioned table, not on one of the partitions.

QUESTION
I'm having problems designing recurrence triggers with logic apps. As far as I know, the logic apps do not support CRON expressions, and running a daily trigger with conditions does not seem to be enough, so I am totally at an loss.
Edit:
To be more precise about my problem, The logic app is for moving files from one server to other and outside constraints dictate that this move should be completed once every month, and the move should happen on the third business day (monday-friday) of the month.
I'm currently pondering on either saving a global variable to tell me whether the app has succesfully ran this month, and using conditions to check every day whether it should run on the day, or starting the running a script which determines if current date is the third weekday of current month, and using that to determine if the logic app should execute or terminate.
...ANSWER
Answered 2021-Dec-28 at 12:14You can use recurrence trigger
in the logic app to trigger the workflow for every three weeks on Monday .
For more information about recurrence trigger you can refer this documentation.
Updated Answer:
As per the requirement, we have created a logic app with recurrence as a trigger & frequency as day. This workflow will fires every day and will validates whether current date is in between (3,4,5) or not. if the condition is succeeded it will further executes the logic app actions.
Here is the logic app that we have created:

...ANSWER
Answered 2022-Jan-03 at 17:55If you are running into performance issues, one area you may want to investigate is how you are chaining array functions (map
, filter
, flat
, etc). Each call to one of these functions creates an intermediate collection based on the array it receives. (For instance, if we chained 2 map
functions, this is looping through the full array twice). You could increase performance by creating one loop and adding items into a collection. (Here's an article that touches on this being a motivation for transducers.)
I haven't encountered a performance issue with this before, but you may also want to remove spread (...
) when unnecessary.
Here is my take on those adjustments on makeTrackObjects
.
Update
I also noticed that you are using includes while iterating through an array. This is effectively O(n^2)
time complexity because each item will be scanned against the full array. One way to mitigate is to instead use a Set
to check if that content already exists, turning this into O(n)
time complexity.

QUESTION
I am trying to find out if there exists a tool that can show realtime traffic flow for springboot + springcloud microservices for my architecture. While searching for such tool, I pondered upon Zipkin's dependency graph. Is it good enough? Or are there any better alternatives to show realtime flow of traffic?
Furthermore, I am seeking an opensource project more than a proprietary solution but I'd be open for either suggestions.
Our architecture is built upon springboot+springcloud hosted in AWS and OCI and using K8s as well.
Any advice/suggestion would be quite helpful.
Attached is zipkin's dependency which is somewhat similar to what I am trying to find out:
Looking forward to it. Kind regards.
