QUESTION
I am working on project upgrade from Vue 2 to Vue 3. The code base changed according to Vue migration documents: https://v3.vuejs.org/guide/migration/introduction.html#overview. I have mismatch of above mentioned libraries. Does somebody has a running project and would share their working library versions
Current mismatch error is :

Answered 2022-Feb-18 at 14:50My colleague solved it by moving to Vite. My suggestion would be to drop webpack and use Vite instead.

QUESTION
I have the following component which utilizes ResizeObserver
(via https://www.npmjs.com/package/@juggle/resize-observer)
ANSWER
Answered 2021-Sep-17 at 18:46I think the issue is that you need to actually resize the element, not simply fire the resize
event.
That is, you actually have to change the width, height or both.
So try the following.
QUESTION
I have an Angular application using Chart.js
3+ and it needs to run in Firefox 68.
Chart.js
3+ uses ResizeObserver
in its code, which is not supported by that specific Firefox version.
So, when I try to load my chart in Firefox, I get the following error:
ReferenceError: "ResizeObserver is not defined"
In other browsers or newer versions of Firefox it works properly.
After some research, I read that I could install a polyfill for ResizeObserver
and many suggested the following: https://github.com/juggle/resize-observer
So I installed it in my project by typing npm i @juggle/resize-observer
and then added it to the polyfill.ts
file:

Answered 2021-Aug-02 at 23:06Looking at how others fixed it, it seems like you still need to register it to the browser before you do anything with chart.js so it can use it:
QUESTION
In analyzing a program with Vtune, I see that the libc
function sched_yield
is flagged as a significant hotspot.
Now I see that this function is roughly responsible for context switching; I say roughly because it's the first time I encounter this function, so my understanding is that it runs inside the OS scheduler to provide support for changing the active thread(s).
What does having sched_yield
as a major hotspot, mean for my program? Does it mean that I create more threads than I should and the OS is trying to juggle continuous context switching?
What would be a remedy for this situation? Maybe resort to more centralized thread pools to avoid over-spawning threads?
What should I analyze next? Are there "typical" next steps in this situation? Vtune already suggests running an analysis for "threading".
...ANSWER
Answered 2021-Jul-29 at 17:19What does having
sched_yield
as a major hotspot, mean for my program?
On Linux, sched_yield
does not necessarily switch to another thread to execute. The kernel does not deschedule the calling thread if there aren't threads that are ready to run on the same CPU. The last part is important, since the kernel will not reschedule a ready to run thread between CPUs upon this call. This is a design tradeoff, as sched_yield
is supposed to be a low cost hint to the kernel.
Since sched_yield
may just return immediately without doing anything, your code may act as having a busy loop around this call, which will look like a hot spot in your profile. Your code just loops around sched_yield
a lot, without doing much else. Such spinning burns a lot of CPU cycles which could be spent for other threads and applications running on the system.
What would be a remedy for this situation?
This depends a lot of your use case. Using sched_yield
may be acceptable when you are willing to waste some CPU cycles in exchange for better latency. You have to be conscious about this decision, and even then I would recommend benchmarking a different solution, with proper thread blocking. Linux thread scheduler is quite efficient, so blocking and waking threads is not as expensive as on some other systems.
Often sched_yield
is used in custom spin lock algorithms. I would recommend replacing these with pthread components, in particular pthread_cond_t
, which allow to properly block and wake up threads. If you're using C++, there are equivalents in the standard library (e.g. std::condition_variable
). In other cases it may be worth exploring other blocking APIs, such as select
and epoll. The exact solution depends on your use case.

QUESTION
I'm trying to setup a workflow that does the following (must work in CI, ie. nothing exists before it runs):
- create a new DB with random name
- install new instance of my Laravel app to new random database name
- run my tests
- still have the test DB around to investigate issue after tests complete
- not have to juggle .env files or edit them in any way
EDIT: It's been suggested to let Laravel Test handle all this because it will wipe then migrate your DB but if I'm understanding correctly, this assumes that the DB already exists, ie. I have to manually create the DB, set it in .env THEN run my script to install the app and run tests. That is not the desired end goal/workflow.
I've got an Artisan command (gist here, cred to this post for a bunch of the code) that seemingly should do all of the above, except running the tests (can't get that far). You can see in the gist or below the numerous ways I've tried telling the command what database to connect to:

Answered 2020-Sep-30 at 02:49I think you can get the results you want by computing the difference between the timestamp of each entry and the timestamp of id = 12

and name < 'Berry'
for the previous row or rows where the difference is >= 0
and name > 'Berry'
for the next row. For example, for the previous row:
