kandi X-RAY | bree Summary
Bree is the best job scheduler for Node.js and JavaScript with cron, dates, ms, later, and human-friendly support. Works in Node v10+ and browsers (thanks to bthreads polyfill), uses worker threads (Node.js) and web workers (browsers) to spawn sandboxed processes, and supports async/await, retries, throttling, concurrency, and cancelable jobs with graceful shutdown. Simple, fast, and lightweight. Made for Forward Email and Lad. :heart: Love this project? Support @niftylettuce’s FOSS on Patreon or PayPal :unicorn:.

QUESTION
Screenshot of problem hereThis is my first post to stackoverflow so go easy on me if I am not doing something right haha.
I'm working on my project for a course I am doing. It's with Bootstrap 4 and the issue I am having is the navbar when being resized starts to lose it's full width. My guess is the content beneath it was causing this but I am not sure how I go about fixing it.
I really would appreciate any guidance here as it's been driving me mental and I know it's possibly somthing so easy but I can't spot what I am doing wrong.
Thanks in advance look forward to chatting.
Mike
...ANSWER
Answered 2021-Jun-03 at 18:40Probably because your .card-about width is wider than your viewport.
Try using max-width instead so. I changed your height into auto so the content wont overflow when the height become bigger.
QUESTION
Premise: I have a calendar-like system that allows the creation/deletion of 'events' at a scheduled time in the future. The end goal is to perform an action (send message/reminder) prior to & at the start of the event. I've done a bit of searching & have narrowed down to what seems to be my two most viable choices
- Unix Cron Jobs
- Bree
I'm not quite sure which will best suit my end goal though, and additionally, it feels like there must be some additional established ways to do things like this that I just don't have proper knowledge of, or that I'm entirely skipping over.
My questions:
If, theoretically, the system were to be handling an arbitrarily large amount of 'events', all for arbitrary times in the future, which of these options is more practical system-resource-wise? Is my concern in this regard even valid?
Is there any foreseeable problem with filling up a crontab with a large volume of jobs - or, in bree's case, scheduling a large amount of jobs?
Is there a better idea I've just completely missed so far?
This mainly stems from bree's use of node 'worker threads'. I'm very unfamiliar with this concept and concerned that since a 'worker thread' is spawned per every job, I could very quickly tie up all of my available threads and grind... something, to a halt. This, however, sounds somewhat silly & possibly wrong(possibly indicative of my complete lack of knowledge here), & thus, my question.
Thanks, Stark.

Answered 2021-Apr-02 at 18:22For a calendar-like system, it seems you could query your database to find all events occuring in the next hour, then create a setTimeout() for each one of those. Then, an hour later, do the same thing again. Then, upon any server restart, do the same thing again. You don't really need to worry about events that aren't imminent. They can just sit in the database until shortly before their time. You will just need an efficient way to query the database to find events that are imminent and user a timer for them.
WorkerThreads are fairly heavy weight items in nodejs as they create a whole separate heap and a whole new instance of a V8 interpreter. You would definitely not want a separate WorkerThread for each event.
I should add that timers in nodejs are very lightweight items and it is not problem to have lots of them. They are just stored in a sorted linked list and only the insertion of a new timer takes a little bit more time (to do an insertion sort as it is added to the list) as the list gets longer. There is no continuous run-time overhead because there are lots of timers. The event loop, then just checks the first item in the linked list to see if it's time yet for the next timer to fire. If so, it removes it from the head of the list and calls its callback. If not, it goes about the rest of the event loop work items and will check the first item in the list again the next through the event loop.

I have a table called subscribers with a name field that contains data like this:
Tom Jones
Drew Brees
Tom Brady III
I need to delete everything after the first space for each record so that it looks like:
Tom
Drew
Tom
Using this question, I assembled the following query:
select substring_index(name,' ',1) as deleteAllAfterSpace from subscribers
I get the following error:
Current selection does not contain a unique column.
When I run:
SELECT * FROM subscribers WHERE INSTR(name, ' ') > 0
I do get the values I'm looking for as described.
I can assure you, name column is unique? What am I doing wrong?

I am trying to pass some wagtail contexts to the search page of a django project. The post title appears but the image, description and other parameters do not appear in the search template. How do I pass these contexts to the search template?
This is the error I get
...ANSWER
Answered 2021-Feb-08 at 10:26It seems like the news_page variable in your template is a string, rather than a page object, as that's the only use of the {% routablepageurl %} tag in the code examples you have shared. However, you don't show where news_page is defined, so I may be mistaken.
I have now looked at your models file, and where you define news_page. You have defined news_page in the context of NewsIndexPage. This will be used when displaying a NewsIndexPage, using Wagtail's internal views, but this is not used when rendering the search view.
Here's the response context you are setting in your search/views.py:

Hello, my animation is not working properly I tried to use document.getElementsByClassName but it won't work at all there's no error is just that the element is not animating properly, I want to do a quick change of color and also a small lettering animation but it will not implement on click, nothing will happen. Please help also if there's any good book about how this works I would appreciate that too.
...ANSWER
Answered 2020-Sep-27 at 04:14When you use document.getElementsByClassName, you are referencing an array of elements with that class. You need to specify which one you want by referring to the element's index. Instead, use document.getElementsByClassName("contentMario")[0].style.animationPlaystate="running";.

I'm trying to make a responsive menu - I'm happy with the desktop version but I have messed up the mobile version of it.
On screens less than 600px how do I get the search bar to appear in the hamburger (ideally at the top with the search icon next to the textbox) instead of underneath that row?
(I'm also trying to make the menu bar sticky and replace the Home with a logo on under600px only, but one thing at a time ...)
Any help gratefully, gratefully, gratefully received. Many thanks in advance!
...ANSWER
Answered 2020-Sep-10 at 10:51- 1st thing is that you are having 2 media queries with maxwidth 600px. Just set one is enought.
- Then I added in your 600px view in class:
.topnav a:not(:first-child)like.topnav a:not(:first-child), .topnav .search-containerlike this, it will work like this other block over. LIke the search bar will bedisplay noneas well - Then I added
.topnav.responsive .search-containerto existing.topnav.responsive ato display. And added order to set search bar on the top
