QUESTION
I am building an app following the Rest Countries API challenge from frontendmentor (https://www.frontendmentor.io/challenges/rest-countries-api-with-color-theme-switcher-5cacc469fec04111f7b848ca). I have run into a problem. When clicking on the router link in countryDetail.js, the url changes but the component doesn't get re-rendered unless the page is refreshed.
CountryDetails.js
...ANSWER
Answered 2021-Jun-15 at 17:07The issue seems to be that you are already on the "/country/:name" path and are clicking to visit another country. The router correctly updates the URL in the address bar, but because CountryDetail is already mounted it neglects to recompute the item and allCountries state. This is because the useEffect hook only runs once when the component mounts.
The name param (match.params.name) is actually a dependency for the GET requests, it should be added to the useEffect hook's dependency array.

I run a loop and append data into a list. I failed to convert the list to a data frame in the loop and only able to fix that in a later step and turn every 3 columns into a new row. I was wondering if I can transform a list into a data frame during the loop session.

QUESTION
I have a custom animation that the regular Vue transition doesn't quite cover. I have it implemented elsewhere with a conditional v-bind:class, but that doesn't work well for conditional v-if blocks or v-for groups.
I need to add a class ('open') one frame after the element is entered as with v-enter-to, but I need it to never be removed from the element.
I then need it removed removed when leaving to trigger the closing animation.
Am I using Vue Transition wrong and this is perfectly possible within transition, or is there a way to add/remove the class around the enter/leave functionality?
...ANSWER
Answered 2021-Jun-09 at 14:25I could only think of a work-around. You could try to add the class in the created() or mounted() hook. Before you push another path to the router, you could remove it and add a fake timeout for the $router.push(path).
This is not clean but i am not sure if i fully understand what are you trying to do.
QUESTION
I have run a topology, and I used the Meter type in metric Reporting API v2. In the execute method I mark this metric. So it will mark an event whenever the execute method is called. But when I compare this value with the __execute-count, I see huge differences. Does anyone know why this happens?
These are the values from my log which are gathered at the same time:
9:v7 __execute-count {v0:v7=44500}
9:v7 tuple_inRate.count 664129
Update: When I use the mark method on the Meter metric, I will get different results in comparison with the Counter metric. But still, I do not understand why the values from the counter metric (tuple counter) are not the same as the __execute-count.
...ANSWER
Answered 2021-Jun-11 at 06:51As given in this answer, Storms Internal Metrics are just estimated by a percentage of the real data flow. Initially, it uses 5% of incoming tuples to make those estimations. This may lead to inaccuracies for extreme high or low throughputs.
EDIT: The documentation describes the following:
In general all of these tuple count metrics are randomly sub-sampled unless otherwise stated. This means that the counts you see both on the UI and from the built in metrics are not necessarily exact. In fact by default we sample only 5% of the events and estimate the total number of events from that. The sampling percentage is configurable per topology through the topology.stats.sample.rate config. Setting it to 1.0 will make the counts exact, but be aware that the more events we sample the slower your topology will run (as the metrics are counted in the same code path as tuples are processed). This is why we have a 5% sample rate as the default.
EDIT 2 In this post, there is more information about the estimation:
The way it works is that if you choose a sampling rate of 0.05, it will pick a random element of the next 20 events in which to increase the count by 20. So if you have 20 tasks for that bolt, your stats could be off by +-380.
By the way, execute_count is just an increasing number, while your tuple_inRate.count is a rate, isn`t it?
QUESTION
So I was really ripping my hair out why two different sessions of R with the same data were producing wildly different times to complete the same task.
After a lot of restarting R, cleaning out all my variables, and really running a clean R, I found the issue: the new data structure provided by vroom and readr is, for some reason, super sluggish on my script. Of course the easiest thing to solve this is to convert your data into a tibble as soon as you load it in. Or is there some other explanation, like poor coding praxis in my functions that can explain the sluggish behavior? Or, is this a bug with recent updates of these packages? If so and if someone is more experienced with reporting bugs to tidyverse, then here is a repex showing the behavior cause I feel that this is out of my ballpark.
ANSWER
Answered 2021-Jun-15 at 14:37This is the issue I had in mind. These problems have been known to happen with vroom, rather than with the spec_tbl_df class, which does not really do much.
vroom does all sorts of things to try and speed reading up; AFAIK mostly by lazy reading. That's how you get all those different components when comparing the two datasets.
With vroom:
QUESTION
I am modeling a Time-constrained CVRP. The problem is to minimize the total travel time (not including the package dropping time) subject to vehicle (delivery) capacity and total time spent (per vehicle) constraints. The package dropping time refers to an additional time to be spent at each node, and the total time spent equals to the travel time plus this additional time. I have the below model that works for a single vehicle-type case. I would like to introduce two-vehicle type concept in there, meaning that I have a set of V1 type vehicles and another set of V2 type vehicles. The only difference of the vehicle-types is the per time cost of travel. Let x denote the per time unit cost of travel by V1, and y denote the per time unit travel cost of V2. How can I design the model so that it incorporates this additional aspect?
ANSWER
Answered 2021-Jun-13 at 13:34Simply register two transits callbacks (i.e. one per vehicle type)
Then use the overload of AddDimension() to pass an array of registered transit callback index.

ANSWER
Answered 2021-Jan-29 at 04:04In my opinion, the CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE setting seems to be wrong.
you can check docker-compose.yaml or core.yaml
- I will explain fabric-samples/test-network as targeting according to your current situation.
- You can check in
CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODEin docker-compose.yaml - Perhaps in your case(fabric-samples/test-network), the value of
${COMPOSE_PROJECT_NAME}was not set properly, so it was set to_test. - Make sure the value is set correctly and change it to your network name.
QUESTION
SpringBoot v2.5.1
There is an endpoint requesting a long running process result and it is created somehow
(for simplicity it is Mono.fromCallable( ... long running ... ).
Client make a request and triggers the publisher to do the work, but after several seconds client aborts the request (i.e. connection is lost). And the process still continues to utilize resources for computation of a result to throw away.
What is a mechanism of notifying Project Reactor's event loop about unnecessary work in progress that should be cancelled?
...ANSWER
Answered 2021-Jun-15 at 09:06fromCallable doesn't shield you from blocking computation inside the Callable, which your example demonstrates.
The primary mean of cancellation in Reactive Streams is the cancel() signal propagated from downstream via the Subscription.
Even with that, the fundamental requirement of avoiding blocking code inside reactive code still holds, because if the operators are simple enough (ie. synchronous), a blocking step could even prevent the propagation of the cancel() signal...
A way to adapt non-reactive code while still getting notified about cancellation is Mono.create: it exposes a MonoSink (via a Consumer) which can be used to push elements to downstream, and at the same time it has a onCancel handler.
You would need to rewrite your code to eg. check an AtomicBoolean on each iteration of the loop, and have that AtomicBoolean flipped in the sink's onCancel handler:
