QUESTION
On a HTML page i have an input with a value attribute which is changed by some library i use. After the user changes the value of the input the value property is changed.
After some action i want to remove the user provided value property and let the input show the value provided by the attribute again, and from that point on, do that automatically (like it did before the user ever entered a value).
I looked at some other questions like What is the difference between properties and attributes in HTML? . They all give a descent explanation ofthe difference between property and attribute however nothing to remove the user filled property.

QUESTION
I have a framework which parses XML for its configuration. I have removed old 1.0 support and am now trying to parse "validators" config. The content of the validators.xsd
is the same (apart from the keyword validators) as in other parts of the framework, which doesn't have any problems. I am only ever told the content model is not determinist hence am finding it hard to problem-solve. If you could point me in the right direction to getting better errors or "sanity-checks" that would be brilliant.
Here is the XSD configuration along with the matching xml notation being used. I'm not sure what to put here but I am going to give everything cited for clarity.
validators.xsd
...ANSWER
Answered 2022-Mar-21 at 15:00So the problem was with the /parts/validator.xsd
config containing a duplicate element which was causing the "non-determinist" error. For reference, it is my understanding that this message means you are seeing a duplicate entry or rather an entry that isn't clear on how to proceed to the next element. Hence, not determinist.

I am working on this challenge:
A bot can do either of the 2 instructions:
- [F]orward: move ahead by +1 and double its speed
- [B]ack: Stop, change direction and reset its speed.
The initial speed is 1.
Given a distance, return a sequence that will satisfy it. The sequence can only have a maximum of 3 'B's. If a solution is not possible with 3 'B's then return empty string.
For example,

Answered 2022-Mar-21 at 10:04The problem with your code was the second turn. Notice that when curr < dist
you change direction but not resetting the speed and adding 'B' to the sequence. Changing

QUESTION
I have implemented a Convolutional Neural Network in C and have been studying what parts of it have the longest latency.
Based on my research, the massive amounts of matricial multiplication required by CNNs makes running them on CPUs and even GPUs very inefficient. However, when I actually profiled my code (on an unoptimized build) I found out that something other than the multiplication itself was the bottleneck of the implementation.
After turning on optimization (-O3 -march=native -ffast-math
, gcc cross compiler), the Gprof result was the following:
Clearly, the convolution2D
function takes the largest amount of time to run, followed by the batch normalization and depthwise convolution functions.
The convolution function in question looks like this:
...ANSWER
Answered 2022-Mar-10 at 13:57Looking at the result of Cachegrind, it doesn't look like the memory is your bottleneck. The NN has to be stored in memory anyway, but if it's too large that your program's having a lot of L1 cache misses, then it's worth thinking to try to minimize L1 misses, but 1.7% of L1 (data) miss rate is not a problem.
So you're trying to make this run fast anyway. Looking at your code, what's happening at the most inner loop is very simple (load-> multiply -> add -> store), and it doesn't have any side effect other than the final store. This kind of code is easily parallelizable, for example, by multithreading or vectorizing. I think you'll know how to make this run in multiple threads seeing that you can write code with some complexity, and you asked in comments how to manually vectorize the code.
I will explain that part, but one thing to bear in mind is that once you choose to manually vectorize the code, it will often be tied to certain CPU architectures. Let's not consider non-AMD64 compatible CPUs like ARM. Still, you have the option of MMX, SSE, AVX, and AVX512 to choose as an extension for vectorized computation, and each extension has multiple versions. If you want maximum portability, SSE2 is a reasonable choice. SSE2 appeared with Pentium 4, and it supports 128-bit vectors. For this post I'll use AVX2, which supports 128-bit and 256-bit vectors. It runs fine on your CPU, and has reasonable portability these days, supported from Haswell (2013) and Excavator (2015).
The pattern you're using in the inner loop is called FMA (fused multiply and add). AVX2 has an instruction for this. Have a look at this function and the compiled output.
QUESTION
Cypress Version: 9.5.0
Chrome Version: 98
Ive been trying to use cy.selectFile()
to upload a file in Cypress test. The following code looks as such:
ANSWER
Answered 2022-Feb-22 at 03:39Since you are selecting the input with force: true
(meaning that the actual input element is hidden from view), one possibility is that perhaps the input that is being referred doesn't have the requirements in place for the selectFile
to succeed. Perhaps in Firefox the input type is inferred from context while in Chrome it would need to be explicitly set.
Have you checked that the element #new-project-photo
passed to selectFile
satisfies this requirement specifically (from the Cypress docs linked above)?
a single input element with type="file", or a label element attached to one
If you could post the element and its context that could help further recreate this scenario and allow testing. Right now from the information available it's not possible to recreate this problem reliably.
QUESTION
I made the following 25 network graphs (all of these graphs are copies for simplicity - in reality, they will all be different):
...ANSWER
Answered 2022-Mar-03 at 21:12While my solution isn't exactly what you describe under Option 2
, it is close. We use combineWidgets()
to create a grid with a single column and a row height where one graph covers most of the screen height. We squeeze in a link between each widget instance that scrolls the browser window down to show the following graph when clicked.
Let me know if this is working for you. It should be possible to automatically adjust the row size according to the browser window size. Currently, this depends on the browser window height being around 1000px.
I modified your code for the graph creation slightly and wrapped it in a function. This allows us to create 25 different-looking graphs easily. This way testing the resulting HTML file is more fun! What follows the function definition is the code to create a list
of HTML objects that we then feed into combineWidgets()
.

I bumped into this while writing a program trying to print the constituent byte values of UTF-8 characters.
This is the program that I wrote to test the various ~0
operations:
ANSWER
Answered 2022-Feb-25 at 18:12When passing a type smaller than int
to a variadic function like printf
, it get promoted to type int
.
In the first case, you're passing char
with value -1 whose representation (assuming 2's complement) is 0xff. This is promoted to an int
with value -1 and representation 0xffffffff, so this is what is printed.
In the second case, you're passing an unsigned char
with value 255 whose representation is 0xff. This is promoted to an int
with value 255 and representation 0x000000ff, so this is what is printed (without the leading zeros).
QUESTION
I am using Ant-transfer for my app. I have two components one is the parent and another is child component. In the child component, I am using the Ant-transfer, Without fetching any data when I play with local state, I can able to transfer the data from one table to another table. And it works as expected.
My case scenario isI have one fixed data. Which contains arrays of objects. From that fixed data, I transfer item from the group table to the target table By using Ant-transfer. After pressing the transfer button(">") which is then called on handleChange
function. After triggering the handleChange
function, it updates the targetKey
local state and does post request.
When an item or items are selected and a post request is made, I retrieve the selected items from the parent component. I filtered the fixed data from the selected items and passed the string id of the items array to the local state. However, when I refresh the page, the fixed data returns to its original state. All items are in the group table, and it does not show select items which should be on the right side of the table. It appears that my filtered function does not work.
Goal:My goal is for selected items to be on the right side and unselected items to be on the left side; if I refresh the page, it should not change.
Reproduce the ant transferI reproduced Ant-transfer-demo.
This is my all code ...ANSWER
Answered 2022-Feb-03 at 07:26If you need to persist any of the state to localStorage to allow reloading the app then it appears you should persist the targetKeys
state.

QUESTION
In local repo:
git checkout -b feature/db/projectImport dev
- make changes
git add .
andgit commit
git push origin feature/db/projectImport
(staying in that branch)
Now in GitHub:
5. Click the Compare & pull request button and finally merge with the default merge button, which claim to use --no-ff
What I want to achieve
- I don't want the commits messages from the feature branch to appear in the commit messages in the dev branch.
- When I merge the
feature
branch intodev
, the feature branch will retain all its commits but thedev
branch will only have the merge commit. Is this possible???
Feature branch commits:
Dev branch commits:
Note:
- I am newbie in
git
. So, my thinking can be wrong. If this is the case, please point out my mistake and tell what is correct. - Any suggestion gratefully received. Thanks in advance.
ANSWER
Answered 2022-Jan-28 at 16:50As others have pointed out in the comments, what you are looking for is the squash option when you merge the PR in.
When you squash-merge, that changes what appears on the destination branch, but it does not change what is on the source branch. So on dev, you'll see one commit. But on the feature branch, as long as you don't delete it, you'll continue to see all your original feature commits. And the PR will continue to hold a pointer to that branch.
Now, that's a bit of a funny workflow to me: when I merge a PR in, I systematically delete the feature branch. But your workflow should work fine too.
How to do it On GitHubOnce you have your PR ready to merge, make sure you merge it in using GitHub's "squash and merge" method:
On the Git CLIIf you're doing the merge on your own computer, the same operation can be accomplished like this:
