How to cancel an announced Android System update

You can not cancel the update itself because it has already been applied.

Modern Android devices have the system partition twice (called A/B partition). One that is currently active and one that can be used for installing updates “seamless” (so called by Google). Which partition is currently active on next boot can be changed.

The screen you show means that an update has been downloaded and installed on the non-active partition. The only step left is rebooting into the updated partition.

I am not sure if you do the reboot but not switch to the updated partition. No matter even if you would manage to do so I assume that the system would start to download and re-apply the update again on the other partition and then ask for rebooting into it to finish the update.

javascript – Name for an async job queue where enqueued jobs cancel pending jobs

Can you help me figure out the name of this object/operation?

I’m writing a form which automatically kicks off a sluggish async job to render a live preview of the results every time the form changes. These automatic jobs should execute sequentially. If the user changes the form before the job is done, the new job should be queued while the running job completes. But if there are other queued up jobs, the other pending jobs should not run. I think I know how I want it to work, and I think I even have a good enough implementation:

class WhatIsThis {
  constructor () {
    this.pending = { 
      promise: Promise.resolve(), 
      tryCancel: false

  queue(asyncAction) {
    this.pending.tryCancel = true;
    const pending = this.pending = {
      tryCancel: false, 
      promise: (() => {
        const doAction = () => pending.tryCancel
          ? { canceled: true }
          : asyncAction();
        return this.pending.promise.then(doAction, doAction);
    return pending.promise;

But, I just don’t know what to call it. It’s not a new concept, it’s not quite a debouncer, and it’s not quite a job/task queue. What is this thing?

air travel – Cancel other person plane ticket that I bought

Any ticket bought can be cancelled by the purchaser. Not all tickets are refundable though, so you may not get your money back. Many but not airlines allow name changes on a ticket, so you could call and see if you can have it changed to someone else. There is a fee associated with this, expect $100-200 USD for standard carriers.

The Airline is going to be your easiest point of contact. No need to give them any reasons. Call and ask to cancel the ticket in question. If it is refundable, they will let you know and ask for information to process the refund. Even if it is refundable, you may not get all money back but it will not be usable by anyone.

It is possible to have a travel agent do that for you. Mostly, if you purchased the ticket through them. Again, they do not need reasons, just to know that you are cancelling that ticket.

You did not specify the itinerary but in some cases the ticket cannot be used without the presence of the purchaser who must show the card used to buy the ticket at check in. Personally, it never occured to be but it is apparently a common practice of some Asian and Middle-Eastern airlines.

gui design – Edit and save or cancel button within a popup

I am not a UX designer but I have a task regarding fixing the UI and would love to hear experts opinion about this issue:
So Here, as you can see :
enter image description here

So the Fix buttons are just like fix/unfix “aka a boolean” just toggle button between fix/unfix! my problem is with the Modify and fix button ..
What I want is when the user clicks on it he can modify Job end/start dates, after that, he can click cancel or fix job time which toggles to unfix
any idea how to achieve that in a good UI/Ux? like how the button changes between the 3 states and to add the cancel button?
