kandi X-RAY | tib Summary
tib aims to provide a uniform interface for testing with both jsdom, Puppeteer and Selenium while using either local browsers or a 3rd party provider. This way you can write a single e2e test and simply switch the browser environment by changing the BrowserString. The term helper classes stems from that this package wont enforce test functionality on you (which would require another learning curve). tib allows you to use the test suite you are already familair with. Use tib to retrieve and assert whether the html you expect to be loaded is really loaded, both on page load as after interacting with it through javascript.

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 have many text documents (items
) that consist of a unique item number (item_nr
) and a text (text
)
The items might be linked to none, one or multiple other items over their item_nr
in the text
I have a few starting items (start_items
) for which I would like to identify trees (lineages) of all linked items until their ends (an item that does not link another one).
Example data
...ANSWER
Answered 2021-May-05 at 13:38This was a fun problem to investigate :-)
Your issue is a classic problem of recursion, which is a kinda hard concept the first time you see it.
As you don't know how many recursions there will be, a long
format is better.
Here, the recursive function will call itself as long as there are links to parse. The escape condition is based on the number of remaining links. However, I added a max_r
value to avoid being stuck in an infinite loop, in the case you have an item linking to itself (directly or not).
The initiation loop (if(r==0)
) is only here to prepare the long format, where a single item can be on multiple rows: there is a source item, a current item and a current recursion number. This should be externalized to simplify the function (then you start at r=1
) if you don't care to change your dataset format.

QUESTION
I've noticed this about 4 days ago and dont know what to do right now. The problem is as follows:
I have a 6 node 3 monitor ceph cluster with 84 osds, 72x7200rpm spin disks and 12xnvme ssds for journaling. Every value for scrub configurations are the default values. Every pg in the cluster is active+clean, every cluster stat is green. Yet PGs not deep scrubbed in time keeps increasing and it is at 96 right now. Output from ceph -s:
...ANSWER
Answered 2021-Feb-09 at 07:14Usually the cluster deep-scrubs itself during low I/O intervals on the cluster. The default is every PG has to be deep-scrubbed once a week. If OSDs go down they can't be deep-scrubbed, of course, this could cause some delay. You could run something like this to see which PGs are behind and if they're all on the same OSD(s):
QUESTION
So this is great example of how selectizeGroupUI and Server works. All of the filters are interactive and choices are update based on other filters selections. But I would like to access for example value
like: input$var_two
and etc. to use in other expressions.
I was trying accesing input$my-filters
using backticksand etc. but everything returns NULL
ANSWER
Answered 2021-Feb-07 at 21:40You can acccess the input value in the server by using both inputIds in brakets (you need to combine both ids with an -): input[["my-filters-var_two"]]
For example I expanded your code to show the selected value for input$var_two
as a text underneath the table.

QUESTION
I want to know How much volume is available to each of EC2
instances in an EKS
cluster?
According to this page, There are two types of AMI
s:
EBS-backed AMI
s with16 TiB
available volume.instance store-backed AMI
s with10 GiB
available volume.
Which one of them does the workers' AMI belong?
I create my EKS cluster using this terraform module:
...ANSWER
Answered 2021-Feb-01 at 21:09You’re using instances of type T2.small. This instance type is EBS-backed only and doesn’t have an instance store option.
According to the documentation that you mentioned, the size limit for an EBS-backed instance’s root device is 16 TiB. The actual size however depends on the volume sizes that you configure for the instances (I’m not sure but I think it defaults to 20 GiB). You can also add multiple EBS volumes to exceed the 16 TiB limit if needed.
QUESTION
Is it possible to create an EC2 instance while reusing already existing VPC?
Running the following code yields Error launching source instance: VPCIdNotSpecified: No default VPC for this user. GroupName is only supported for EC2-Classic and default VPC.
(status code: 400
):
ANSWER
Answered 2021-Jan-23 at 15:40Yes, you can add a new EC2 instance to an existing VPC.
You should provide the subnet_id
to aws_instance. You would typically pass that into Terraform as a parameter, rather than hard-coding its value into your template.
Note: the subnet ID implicitly indicates the actual VPC (because a subnet only exists in one VPC).
