QUESTION
6.2 Methods with a Pointer Receiver
If all the methods of a named type T have a receiver type of T itself (not *T ), it is safe to copy instances of that type; calling any of its methods necessarily makes a copy. For example, time.Duration values are liberally copied, including as arguments to functions. But if any method has a pointer receiver, you should avoid copying instances of T because doing so may violate internal invariants. For example, copying an instance of bytes.Buffer would cause the original and the copy to alias ( §2.3.2 ) the same underlying array of bytes. Subsequent method calls would have unpredictable effects.
(The Go Programming Language Alan A. A. Donovan · Brian W. Kernighan)
I understand the general meaning of the quote, but I am wondering whether it's correct to say that is safe to copy instances of that type.
If a struct has a slice/map field then all copies receive their own copies of the pointers to the backing array/hashmap so it is still possible to mutate those data structures.
Even though all the methods might be defined using value receivers, we can break the internal state of the struct.
I understand why that happens, but doesn't that possibility contradict what is written in that paragraph above?
Copying values might have unwanted consequences regardless of the method receivers and also depends on the field types.
What am I missing here?
...ANSWER
Answered 2022-Feb-03 at 18:27I'm neither Donovan nor Kernighan, so I can't definitively say what they were trying to communicate here, but my understanding is not that "using value receivers makes copying safe", but rather "using value receivers indicates copying is safe". You are correct that any pointer field, or any field which contains a pointer field (including slices and maps), will make copying unsafe; I believe what the authors are trying to get across is that an API which uses a value receiver is indicating to its consumers that no such fields exist.
QUESTION
Something I often see in e-commerce websites is a sidebar with checkboxes for various filtering values. Many of these can be checked, and adding new values further narrows down your search.
I want to implement something similar for metadata pertaining to digital media. I have an array of possible filters, each of which is an object {nameOfProperty: ['Value1', 'Value2']}. The idea is to return results that satisfy ALL of the criteria in an array of attributes {value: 'Value1', trait_type: 'NameOfProperty'}.
See example:

QUESTION
I'm building an NFT marketplace, say a copycat of OpenSea.
I need to make my users able to mint their own tokens. That's ok, that would be an ERC721 contract. But I want to allow my users to mint different collections (as OpenSea does) with different supplies as follows:
(1) Have a single collection
(2) Have multiple collections
(A) Mint 1/1 NFTs
(B) Mint 1/N NFTs (say, for instance, 100 in total of the same NFT)
That makes a set of combinations:
Single collections (1) of 1/1 NFTs (A)
Single collections (1) of 1/N NFTs (B)
Multiple collections (2) of 1/1 NFTs (A)
Multiple collections (2) of 1/N NFTs (B)
Single or multiple collections (1 or 2) of both 1/1 and 1/N NFTS (A and B)
When using ERC721 I would be able to make (A) and (B), yet for every collection I would have to deploy a new contract. I want to avoid this.
Is this covered by ERC1155?
...ANSWER
Answered 2022-Jan-05 at 00:17(A) Mint 1/1 NFTs
(B) Mint 1/N NFTs (say, for instance, 100 in total of the same NFT)
Both options are in accordance with the ERC-1155 standard.
The ERC-1155 defines a collection of tokens, where each token has an ID and an amount (specified as a value in the standard). Which means, you can have for example:
- Token ID 1 that has amount of 1. At any point in time, it's always owned by just one address. (Case A)
- Token ID 2 that has amount of 10. Five of these tokens ID 2 is owned by Alice, and other five tokens ID 2 is owned by Bob. (Case B)

Is there a github action which allows me to copy specific folders (.eg. dist and static) from one branch to another in the same private repo. I appreciate any help. here is what was trying to get it to work using Copycat action.
...ANSWER
Answered 2021-Oct-14 at 23:13If you want to commit to the same repository, you don't have to specify a personal token, just use actions/checkout@v2 (see this)
One solution to copy files between branch is to use git checkout [branch] -- $files, see this post
The following workflow copy files from directory named static on source branch to branch named dest:
QUESTION
The title is self explanatory... I was configuring AwesomeWM and suddenly realised that none of my dropdown menus were working (they were working fine before). Actually, I noticed that they were working, but are completely invisible. This happens in application menus (like the top menu on pcmanfm) and in desktop, when I right click. For example, in Notepadqq, if click on the Search menu on the top, nothing appears, but I can move down the mouse, left click, and the search tool appears; the same occurs in desktop, where I can can right click and nothing will show up, but moving the mouse to where the apps would appear and left clicking, the selected app opens. The menu is there, I can click stuff, but I don't know what I'm clicking. The only one that is normal is Vivaldi's menu. I really don't know what I did to cause that, and would appreciate any help.
I don't think there's something wrong with my rc.lua file, but here is a part of it:
ANSWER
Answered 2021-Oct-14 at 21:38This is probably due to using a compositing manager like compton or picom. You can either try another compositing manager, update your graphics driver.
You can also try to start Awesome with --no-argb. This will disable some features like true transparency in the titlebars, but is closer to what other window manager use, so tends to trigger less bugs in the graphics driver or compositing managers.
QUESTION
I am working on the cs50 web development Network assignment. Essentially it is a barebones twitter copycat. I have an issue where a view from views.py is being called when I do not intend it to be called. I know below I am posting more than is needed of my code below, but I feel I need to since I don't know where the problem area is.
The views.py function follow_count() is being called eventually when I call the index view but cannot determine why. I.e. it is called every time the homepage is loaded. I do not want it to be called until it is specifically called by the clicked event listener in the js file. I cannot figure out what is causing follow_count() to run early, every time I load the index view. As I follow the path of different functions calling each other, it doesn't appear that anything is calling follow_count() yet it runs anyway.
views.py:

Answered 2021-Aug-23 at 20:56You need to put profile_info before the , otherwise that will be the first match, and thus fire the follow_countinstead of thefollow_button`:

I am new to prolog and I'm having trouble with this problem. I am taking a sentence as input and put [Anne,do,you,know] in front of the sentence and replace any occurrence of you to I.
For example copycat([you,love,me], X) will return X = [Anne,do,you,know,i,love,you].
...ANSWER
Answered 2021-Mar-10 at 09:17First of all, you need to break this in two parts, since you want to replace every suitable element of the list by something, but you only want to add [Anne, do,you,know] once.
So you could define your predicate like this:

Answered 2021-Mar-08 at 11:33The callback associated with on_press is executed in a secondary thread so your implementation is updating the GUI from a secondary thread which Qt prohibits, instead you should use the signals as they are thread-safe.
