QUESTION
I'm trying to understand how the importlib.reload method actually behaves. I'll give a boiled down example
...ANSWER
Answered 2022-Mar-21 at 06:46This is an import system bug, Python issue 31772. If a source file is updated quickly without changing the file length, the import system won't realize that it's changed.
Your importlib.reload
call is reexecuting stale bytecode instead of rereading the file. That's why var
isn't updated to the new value - the import system is using the old bytecode for the var = 1
version of the file.
QUESTION
Very perplexed with this one. I have three implementations of an algorithm to calculate the factorial of a number. I calculated the average runtimes of each for input size up to 2500 and plotted them. From the visual inspection it seems that they don't exhibit linear time complexity but rather quadratic. To explore this further, I used curve fitting and the results emerging from visual inspection are confirmed.
Why is this happening? Is it maybe related to the way multiplication is handled in Python for small number? (see here Complexity of recursive factorial program)
...ANSWER
Answered 2022-Mar-15 at 15:48As @Konrad has pointed out, it is due to the way multiplication is handled in Python.
For smaller numbers, simple school level multiplication (which runs in O(N^2)
) is used. However, for bigger numbers, it uses the Karatsuba Algorithm, which has a estimated complexity of O(N^1.58)
(N
= length of the number). Since the multiplication isn't achieved in O(1)
, your time complexity isn't linear.
There are "faster" multiplication algorithms (such as Toom-Cook and Schönhage-Strassen) if you want to look into it.
QUESTION
I have a set up where once the artworks are displayed, there's the name and occupation of the participant on the left. I have managed to make it sticky so we can scroll through the images and have their name on the left. now I want that once the images of the first participant are done, that their name also scrolls out (so sticky ends) and that the new participant name can take over with their image. rigth now they overlap. I need to figure out how to make it exit with the last image.
The CSS class sections I am talking about are .name and .occupation / .nameb and .occupationb
Here is my code:
...ANSWER
Answered 2022-Feb-27 at 17:00The easiest way to solve this is to add the content into sections. A sticky
element will not be moved completely out of flow. So it remains an element within it's parent element and as such will leave the viewport if the parent element leaves it aswell.
I added a section just for the h1
up to the enxt h2
element to demonstrate the solution:
QUESTION
Issue description: Brownie tests containing either
...ANSWER
Answered 2022-Feb-19 at 19:52This is fixed in Brownie v1.18.1. However, you will need to install Python 3.9.10 in order to get the latest brownie. For this to work in a virtual environment you can't use venv. Here is a process that works for me:
- install virtualenv on your standard Python version
- download python 3.9.10 and install it without "add to path" into a dedicated directory e.g. $home/pythonversions
- in your project directory create a virtual environment like so
python -m virtualenv -p=""
start your virtual environment e.g. home>..venv\Scripts\activate.ps1
test if your python version is the desired one with python --version
Now install Cython to avoid another error.
Install nodeenv in order to install ganage
Activate with
nodeenv -p
(for this step you will need PowerShell with admin rights)Install ganache with npm
Install eth-brownie with pip check if you got the latest version with
brownie --version
QUESTION
Apparently, discord bots can have mobile status as opposed to the desktop (online) status that one gets by default.
After a bit of digging I found out that such a status is achieved by modifying the IDENTIFY packet
in discord.gateway.DiscordWebSocket.identify
modifying the value of $browser
to Discord Android
or Discord iOS
should theoretically get us the mobile status.
After modifying code snippets I found online which does this, I end up with this :
...ANSWER
Answered 2022-Feb-07 at 23:03The following works by subclassing the relevant class, and duplicating code with the relevant changes. We also have to subclass the Client
class, to overwrite the place where the gateway/websocket class is used. This results in a lot of duplicated code, however it does work, and requires neither dirty monkey-patching nor editing the library source code.
However, it does come with many of the same problems as editing the library source code - mainly that as the library is updated, this code will become out of date (if you're using the archived and obsolete version of the library, you have bigger problems instead).
QUESTION
I have an AVPlayer that is playing a moderately large video (~150mb). When loading the video initially, I find that the player remains idle for upwards of 10-15 seconds in the AVPlayerWaitingWhileEvaluatingBufferingRateReason
state. My question is simple: how can I prevent AVPlayer from "evaluating the buffering rate reason" for this long and instead move to immediately playing the video?
I am using a custom resource loader (although this same behaviour is exhibited without using a custom resource loader). Here is the relevant code for creating the AVPlayer (all standard boilerplate):
...ANSWER
Answered 2022-Feb-07 at 17:31Apple has confirmed that the issue is not the size of the video, but instead a malformed MP4 with too many moof+mdat atoms.
At this point in time, this has been determined to be working as intended. Although, I would like to see some way to avoid this initial buffering in the future, even if the MP4 is malformed.
QUESTION
The following example compiles with both gcc 11 on Linux (GNU STL) and clang 12 on FreeBSD (Clang STL). On Linux, it runs and prints values 1 and 2. On FreeBSD, it prints value 1 and then crashes with a SEGV. I don't quite understand the object lifetimes -- so the whole thing may be UB and the runtime behavior might not be relevant. I do know that the implementation of std::unique_ptr
between those two STLs differs in an important way: Clang STL resets the internal pointer of a std::unique_ptr
to nullptr
at the start of the destructor, while GNU STL leaves the pointer alone.
ANSWER
Answered 2022-Jan-24 at 10:41Yes, the lifetime of the object that m_owner
refers to has already ended and it's destructor call completed when m_owner->cleanup();
is called. The call is therefore UB.
QUESTION
While monkey-patching a module from a Rails engine, we found that if you prepend a module B to another module A, the prepended module B won't be added to the ancestors of classes that have already included module A prior to the prepend
. To illustrate:
ANSWER
Answered 2022-Jan-21 at 07:05https://bugs.ruby-lang.org/issues/9573 shows a similar behavior concerning classes and modules. The bug report was posted on 2014 and was only closed 2020. Based on that report, I've manually confirmed that
- This behavior still appears in ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-linux], but
- This behavior no longer appears in ruby 3.0.0p0 (2020-12-25 revision 95aff21468) [x86_64-linux]
QUESTION
There's a classical problem with setInterval()
in browsers - if some JS code or other browser process takes too long to complete, several callback invocations might get "backed up" and you suddenly end with your callback executed multiple times in quick succession.
Often this is not what is desired when setInterval()
is used. It's a typical use case when you want AT LEAST some interval of time to pass between invocations. The workaround to this is to use setTimeout()
instead and only schedule the next invocation when the previous is completed.
This works well but also is extra code and might be confusing for someone who does not understand the issue.
I know that NodeJS works differently than browsers, but I cannot find any information on this particular aspect. Does NodeJS also exhibit the same behavior, or does it guarantee a minimum time between invocations when using setInterval()
?

QUESTION
i'm working on a full screen menu for a website but I need to disable the user to scroll while the menu is open. I can't find a fitting solution on the internet so it would be great if anyone could help me. I am not sure how to trigger the body to no-scroll if the menu is open. I am not that familiar with js.
Here is my code at the moment:
...ANSWER
Answered 2022-Jan-04 at 11:28I used document.querySelector('body').classList.add('no-scroll')
when menu opened & document.querySelector('body').classList.remove('no-scroll')
when menu closed.
