QUESTION
this is a codepen demo at here and you try to click on the canvas and is able to undo and clear the grid. The problem I am trying to solve is I want to place some numbers (in black) in the red square. For example, when you click on the grid, first red dot will appear and inside labelled as 1 and the second will be labelled 2 and so on and if the dots overlap, it will just show the original number(not a new number). I have tried to use the code below:
...ANSWER
Answered 2022-Apr-10 at 04:09This should do it:
- accessing elements by classname needs to be by index e.g
document.getElementsByClassName(.red-dot)[0]will access the first element with the classname red-dot - in the codepen you used style top and left to position the red-dot, so i used it as skip if taken by an element of the same class name
The rest is self explanatory.
QUESTION
If I run git fetch origin and then git checkout on a series of consecutive commits, I get a relatively small repo directory.
But if I run git fetch origin and then git checkout FETCH_HEAD on the same series of commits, the directory is relatively bloated. Specifically, there seem to be a bunch of large packfiles.
The behavior appears the same whether the commits are all in place at the time of the first fetch or if they are committed immediately before each fetch.
The following examples use a public repo, so you can reproduce the behavior.
Why is the directory size of example 2 so much larger?
Example 1 (small):
...ANSWER
Answered 2022-Mar-25 at 19:08Because each fetch produces its own packfile and one packfile is more efficient than multiple packfiles. A lot more efficient. How?
First, the checkouts are a red herring. They don't affect the size of the .git/ directory.
Second, in the first example only the first git fetch origin does anything. The rest will fetch nothing (unless something changed on origin).
Compression works by finding common long sequences within the data and reducing them to very short sequences. If
long block of legal mumbo jumbo appears dozens of times it could be replaced with a few bytes. But the original long string must still be stored. If there's a single packfile it must only be stored once. If there's multiple packfiles it must be stored multiple times. You are, effectively, storing the whole history of changes up to that point in each packfile.
We can see in the example below that the first packfile is 113M, the second is 161M, the third is 177M, and the final fetch is 209M. The size of the final packfile is roughly equal to the size of the single garbage compacted packfile.
Why do multiple fetches result in multiple packfiles?git fetch is very efficient. It will only fetch objects you not already have. Sending individual object files is inefficient. A smart Git server will send them as a single packfile.
When you do a single git fetch on a fresh repository, Git asks the server for every object. The remote sends it a packfile of every object.
When you do git fetch ABC and then git fetch DEFs, Git tells the server "I already have everything up to ABC, give me all the objects up to DEF", so the server makes a new packfile of everything from ABC to DEF and sends it.
Eventually your repository will do an automatic garbage collection and repack these into a single packfile.
We can reduce the examples. I'm going to use Rails to illustrate because it has clearly defined tags to fetch.

currently, I try to build a spring boot application and make releases with Azure Pipelines and maven-release-plugin.
My Azure Pipeline YAML Looks like this:
...ANSWER
Answered 2022-Feb-09 at 08:01Ok, I found a solution for me that involves using the Azure DevOps Git SSH URL and not the HTTPS.
First of all, I created a SSH Key according to this Use SSH key authentication or choose your Git providers tutorial.
Once you have your SSH private and public key, you need to install the SSH Key into your YAML pipeline. See Install SSH Key task.
QUESTION
A few months ago I played around with AWS CDK and so I of course did the cdk bootstrap.
At that time I stopped playing around and thought I'd never use it again. Having a kind of neatly attitude in this kind of things (and missing an undo or delete option being delivered with the cdk itself :/ ) I deleted all cdk objects from my account.
Or at least I thought so, because now (starting to play around again), calling cdk bootstrap does "nothing":
✅ Environment aws://xxxxxxxxx/eu-central-1 bootstrapped (no changes).
But trying to cdk deploy gives me:
fail: No bucket named 'cdk-XXXXXXXXXXX-eu-central-1'. Is account XXXXXXXXXXXX bootstrapped?
Well yes right...I don't have any buckets at all at the moment.
Is there a way to cdk bootstrap --force that I'am missing? Is there a list of all objects I should have deleted? I find a lot suggestions for people having problems with their stacks, but I have no idea how to fix this.
Edit: I just "solved" the problem, by creating a bucket with the given cryptic name...but that doesn't feel right. So I leave this Question open, to see if there is a better way to do it.

Answered 2022-Feb-27 at 10:25Bootstrapping creates a Stack called CDKToolkit, which has the CloudFormation resources CDK needs to deploy. You can safely "uninstall-reinstall" it:

QUESTION
My logic is simple, create a state array and a stateIndex, when the user interacts with the drawing, save the current state as an entry in the array and increment the stateIndex.
When the user presses "undo" (for this sketch press any key), decrement the stateIndex and draw to the page whatever value is in state for that index.
I've implemented it in this sketch https://editor.p5js.org/mr_anonymous/sketches/s0C1M7x1w but as you can see instead of storing the last state of the drawing it seems to only store the blank state.
Anyone know what's going wrong?
Edit: Added source code
...ANSWER
Answered 2022-Feb-23 at 08:52You're using the set() function incorrectly. While get() can be used to get a p5.Image object, there is no overload of set() that takes one (a bit idiosyncratic, I know). Instead you'll want to use the image() function:
QUESTION
I am using Jupyter notebook (from anaconda Jupyter lab) on Windows 10 and tried to undo/redo changes in the selected cell. However, I can only undo/redo changes in the whole notebook.
For example, I edited cell#1 then cell#2. Say I want to undo changes in cell#1, so I go to cell#1 and press control+z, it will however undo the change in cell#2.
My friend using Mac doesn't have this issue. Are there any settings for this? I searched online and didn't find anyone who has the same problem. It is so weird!
...ANSWER
Answered 2021-Oct-14 at 20:04This global undo/redo is a new feature that enables Real Time Collaboration which was added in JupyterLab 3.1. It is indeed sub-optimal for many use cases.
JupyterLab 3.2 allows to disable notebook-wide history tracking (see issue 10791 nad PR 10949), but with a caveat: when moving cells you may loose the undo history, which is why the setting is marked as experimental (it requires more work to be exposed or enabled by a default). To get the selective undo/redo please add:

Answered 2022-Feb-09 at 10:43The pushd command without any arguments lists the contents of the directory stack, which can be made use of, by writing the list with output redirection > to a (temporary) file, which is then read by a for /F loop, and to determine how many popd commands are necessary.

QUESTION
The 'Thanks' pop-over when clicking the thumbs up for the first time appears, but it is still appearing the second time the thumbs up is clicked even after setting its trigger to 'none'
Steps to reproduce:
- Click any thumbs up, 'Thanks' pop-over will appear
- Click anywhere outside such as white area to dismiss the 'Thanks' pop-over
- Click again that thumbs up and the 'Thanks' pop-over is still appearing
In the code, I set my own custom directive to conditionally set the popover-trigger such that when thumbs up is clicked once, it will set the popover-trigger to 'none': Inspected in Element tab that popover-trigger is really set to none.
Code in html:
...ANSWER
Answered 2022-Feb-06 at 11:36You try to change the DOM via injection attrs.$set('popover-trigger', "none") and this is not recognized by the compiled AngularUI template. You could recompile the template but this is not needed. Your approach is to complex for such simple requirement. Simply us the popover-enable option and you will be fine. You don't need to handle this inside a directive. Also $watch is not needed.
