QUESTION
I am trying to mirror the google image search. so far I know that q is the name for the actual google search (or query). On the address it will look: www.google.com/search?q=parrot but on the google image search also appears /search?q=parrot&tbm=ish
I looked and found out that tbm stands for "to be match" and is a filter and I guess is the filter to match the images... but I don't have a clue how to put inside my html code.
So far I have done this:

I’m using R to prepare data to input into a model (written in Fortran, compiled into an .exe).
The model requires a text file as input which I'm generating using R. In the end it’s mostly just a list of variables (like ‘VARIABLE_X = 0.6’). The value of these variables is based on some processing I'm doing in R. An example on how the generated text file partly looks like;

I'm working on a theme for a little app where I need to place some toggle buttons. Like showed in many place this site, I've done it using a checkbox and changing the apparance by a custom onpaint event ,(basically a draw it like a button). Then I realize that checkbox not grouping like radio buttons, so I've done the same with a radio buttons, but even if I place 2 of them in a groupbox, I still can "checked" them both; which is the best way to do that? here sample code that I used to make some test:
...ANSWER
Answered 2021-Jun-13 at 13:04Yes you can imitate the behavior of a group of RadioButton controls in a container. Just find the controls of the same type in the Parent.Controls
collection and uncheck them when the current instance is checked.

Add this method to MyToggleButton
class.
QUESTION
I wonder if there is more or less standard way of creating a coroutine context/scope such that:
- It is a child of a current coroutine for structured concurrency,
- It can be stored in some property, etc. and later be used for running asynchronous tasks with e.g.
launch()
.
coroutineScope() does exactly what I need, it creates a child scope, but it does not simply return it to the caller - we need to pass a lambda and coroutine lifetime is limited to the execution of this lambda. On the other hand, CoroutineScope() factory creates a long-running scope that I can store for a later use, but it is unrelated to the current coroutine.
I was able to create such a scope manually with:
...ANSWER
Answered 2021-Jun-08 at 16:56I found a really great answer and explanation to my question. Roman Elizarov discussed exactly my problem in one of his articles: https://elizarov.medium.com/coroutine-context-and-scope-c8b255d59055
He explained that while it is technically possible to "capture" a current context of a suspending function and use it to launch background coroutines, it is highly discouraged to do this:
Do not do this! It makes the scope in which the coroutine is launched opaque and implicit, capturing some outer
Job
to launch a new coroutine without explicitly announcing it in the function signature. A coroutine is a piece of work that is concurrent with the rest of your code and its launch has to be explicit.If you need to launch a coroutine that keeps running after your function returns, then make your function an extension of
CoroutineScope
or passscope: CoroutineScope
as parameter to make your intent clear in your function signature. Do not make these functions suspending.
I knew I could just pass a CoroutineScope
/CoroutineContext
to a function, but I thought suspending function would be a shorter and more elegant approach. However, above explanation makes hell a lot of sense. If our function needs to acquire a coroutine scope/context of the caller, make it explicit about this - it can't be simpler.
This is also related to the concept of "hot"/"cold" execution. One great thing about suspending functions is that they allow us to easily create "cold" implementations of long-running tasks. While I believe it is not explicitly specified in the coroutines docs that suspend functions should be "cold", it is generally a good idea to meet this requirement as callers of our suspending function could assume it is "cold". Capturing the coroutine context makes our function "hot", so the caller should be notified about this.
QUESTION
I am trying to extract the year, make, model, colour and plate number from carjam.co.nz. An example of a URL I am scraping from is https://www.carjam.co.nz/car/?plate=JKY242.
If the plate has been recently requested, then the response will be a HTML document with the vehicle details.
Result where the plate details have been recently requested.
If the plate details haven't been recently requested (as is the case with most plates) the response is a HTML document with "Trying to get some vehicle data". I'm guessing that this page displays while the information is fetched from the database, then the page is reloaded to show the vehicle details. This appears to be rendered server-side, I can't see any AJAX requests.
The URL is the same for each result.
Result where the vehicle hasn't been recently requested.
How do I 'wait' for the correct information?

You can reproduce this flow, so that you have exactly the same behaviour as the frontend code.

QUESTION
I am trying to run a distributed computation using Dask on a AWS Fargate cluster (using dask.cloudprovider
API) and I am running into the exact same issue as this question. Based on the partial answers to the linked question, and on things like this, I heavily suspect it is due to the pandas version in my worker being outdated; and indeed the
official Dask Dockerfile specifies a old-ish version of pandas.
By contrast, when I run my computation locally (using a distributed.LocalCluster
) with a pandas version at 1.2.2
it works fine. Btw, it is a call to the categorize
method on a Dask DataFrame that triggers the error in the Fargate cluster case.
What I would like to do as a workaround is simply to specify myself the version of pandas in the image deployed to the workers, either building a custom image myself + putting it on an image repo + have the worker use it, or through some other method. Is there a way to achieve this?
...ANSWER
Answered 2021-Jun-07 at 23:35One option that might work is to pass environment variables, such as EXTRA_CONDA_PACKAGES
and EXTRA_PIP_PACKAGES
, to indicate the package versions you would like to install, which it looks like should be supported by dask.cloudprovider
as seen here, and also noted in the dask-docker
repo you linked. They would be passed as a dict via a parameter environment
.
Another option would be to build and push your own image as you mentioned, which also appears to be supported by dask.cloudprovider
as indicated here. The image tag would be passed to the cluster constructor via the image
parameter.
The options linked are for ECSCluster
, which FargateCluster
inherits from, as seen here.

Answered 2021-Jun-07 at 14:53so the answer has nothing to do with overlay. Actually, all the new pages will place on top of each other if you set various pages to open like a swipe up modal like that, and the page that you have not set to up like this but instead place like a full page, this full page will be placed in the very bottom. With this, if you set a black view wrapping your routes, will give a black background effect as desired.
QUESTION
How can I efficiently calculate distances between (almost) consecutive rows of a large-ish (~4m rows) of a data.table? I've outlined my current approach, but it is very slow. My actual data has up to a few hundred columns. I need to calculate lags and leads for future use, so I create these and use them to calculate distances.
...ANSWER
Answered 2021-Jun-03 at 23:07You aren't using the vectorisation efficiencies in the proxy::dist
function - rather than call it once for each row you can get all the distances you need from a single call.
Try this replacement function and compare the speed:

does not make any distinction between different rules; it just falls back to the next possible accepting pattern (which might not even be shorter, if there's a lower-precedence rule which matches the same token.) That might be a shorter match of the same pattern. (Normally, Flex chooses the longest match out of the possible matches of the regular expression. With REJECT
, the shorter matches are also considered.)
So you can avoid the false match of A::B
for input A::BB
