kandi X-RAY | dvm Summary
An on demand Docker virtual machine, thanks to Vagrant and boot2docker. Works great on Macs and other platforms that don't natively support the Docker daemon. Under the covers this is downloading and booting Mitchell Hashimoto's boot2docker Vagrant Box image. The driving need for something like dvm was for running infrastructure testing, like Test Kitchen using the kitchen-docker driver. For the driver to work it needs access to all the dynamically assigned ports, not just the Docker daemon port. That's why dvm uses a private network segment and address (192.168.42.43 by default). Once Docker started supporting the DOCKER_HOST environment variable, the actual IP address was less important and consequently made the docker command on non-Linux distros feel almost native.

QUESTION
I tried to delete an array of array within an array if certain values existed
But I am getting this error
...ANSWER
Answered 2022-Jan-18 at 06:49The code you've provided works, you can test it in your browser's console.
The problem is you're trying to use Array methods on a variable that isn't an Array, so it's not recognizing those functions. if you're returning an answer with Fetch API make sure you add await/async or .then().

QUESTION
What is the best way to parse common data from an object and an array to get a specific value from the current data.
In this case I am looking at current_data[3] and dog_database.vets to see the output of current_data[4].
ANSWER
Answered 2022-Jan-17 at 20:10Not sure there is a "best" way because it very much depends on the shape of your data. But what you have isn't far off.
It seems like a small helper function might make this more extensible. Something like
QUESTION
I have a form having mutiple checkbox and related textarea fields for taking comment. Please check demo here
When user selects checkbox first and then enter value in comment then comment value does not get store. If user enters comment value first and then checks the checkbox then value gets added.
textarea values are optional. If user checks checkbox then comment should get added. if checkbox is checked and then comment is entered then comment should get added. If comment is added first and then checkbox is checked then also comment should get added. If that checkbox is uncheck then that should get remove. The behavior should be same with select/unselect all option.
How should I do this?

...ANSWER
Answered 2021-Dec-10 at 19:11As I had some time I thought I would write up a possible solution for you... Mentioned in comment, I would suggest a form as you have checkbox required if textarea has value. Here is a reactive approach to that.
I have created a formgroup, you don't necessarily need it, you could also just use a formarray, without a parent form.
Anyways, in this case I declare a formgroup with a formarray where we will store our values, then we populate the formarray based on your array. We listen to changes to each textarea, and if it has a value, we set Validators.requiredTrue (requiredTrue is used for checkboxes), otherwise we clear it with clearValidators. Lastly we update the value and validity of the formcontrol with updateValueAndValidity.
We can use a separate formcontrol for the check / uncheck all checkbox, which I have named here as masterSwitch ;)
We listen to the changes of that field and update the values in the form array as well as clear any possible requiredTrue validators if the value is true.
So the explained above translates to the following TS code:

The goal is to have a Spark Streaming application that read data from Kafka and use Delta Lake to create store data. The granularity of the delta table is pretty granular, the first partition is the organization_id (there are more than 5000 organizations) and the second partition is the date.
The application has a expected latency, but it does not last more than one day up. The error is always about memory as I'll show below.
OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000006f8000000, 671088640, 0) failed; error='Cannot allocate memory' (errno=12)
There is no persistence and the memory is already high for the whole application.
What I've triedIncreasing memory and workes were the first things I've tried, but the number of partitions were changed as well, from 4 to 16.

QUESTION
I'm trying to create a horizontal bar chart that visualizes abundance at specified depth intervals at both day and night. Essentially for those who are familiar with diel vertical migration (dvm), I'm trying to visualize that.
Here's a link to an example of what I'm talking about, specifically the bottom part of the figure. And another one.
I've been able to get this so far
but I'd like to make the duplicates go side by side instead with the middle divider indicating the change in day vs. night. So instead of it going 5, 4, 3, 2, 1, 5, 4, 3, 2, 1 on the y-axis it will have one set of 5-1 on the left and another set on the right, with the columns being directly side-by-side. Having one side shaded and another white would be super useful also! I'm also wondering how to add the error bars for the standard deviation too.
Here's the code that I have so far:
...ANSWER
Answered 2021-Jun-06 at 09:45I think this is what you're looking for :-)
The ggplot2 and dplyr libraries would be useful to you! You can use dplyr::filter to extract all the Fish data instead of manually doing so for each variable.
Then, you can use ggplot to make the graph. I plotted Day with correct Average values, and the Night data with negative Average values. Then, flipped the coordinates (so the graph is verticle). Then, relabeled the y-axis since you won't want to show negative values.
